Can't seem to retrieve stripe charge using python
|
<p>I have the following python code to create a charge in stripe.</p>
<pre><code>a_charge = stripe.Charge.create(
amount=cents,
currency="usd",
source=token,
description="my_description",
application_fee=application_fee,
stripe_account=teacher_stripe_id
)
</code></pre>
<p>This succeeds (I think), because it shows up in my dashboard with a charge_id.
But then, immediately after in the code, the following fails:</p>
<pre><code>stripe.Charge.retrieve(a_charge.id)
</code></pre>
<p>With error:
No such charge: somelongstringhere</p>
<p>However, somelongstringhere is indeed the ID under charge details on my stripe dashboard. So how come Stripe can't retrieve this charge? Is this not the correct id?</p>

How to get general user information with SteamID64?
|
<p>I am having problem with doing simple things using Steams 64 bit id. </p>
<p>How can i use SteamAPI to get the general information? like displaying name, username, location.</p>
<p>I used SteamAuth to make my social authentication on website, which only has the function, that gets the id.</p>
<p>Example:</p>
<pre><code>steamid = GetSteamID64()
username = GetUsername()
displayname = GetDisplay()
...
</code></pre>
<p>Does SteamAPI on have features related to this? is there any library in python that could support such thing?</p>

Is it possible to disable "Double-tap for period" in an Android EditText?
|
<p>It's been messing up my Edit Text filter. When I double-tap space, the previous character is deleted instead. Here is my filter:</p>
<pre><code>@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
if (!isValid(source)) { // This simple calls Matcher.matches
return "";
}
return null;
}
</code></pre>
<p>When I double tap the space key, the filter is called three times with the following sources:</p>
<ol>
<li>Source with a space source (" ")</li>
<li>An empty source ("") (similar to a backspace) --> This one deletes the last character</li>
<li>A ". " source</li>
</ol>
<p>I tried just retaining the last character instead:</p>
<pre><code>if(source.toString().isEmpty()) {
return ((Character) dest.toString().charAt(dest.toString().length()-1)).toString();
}
</code></pre>
<p>It fixed the issue but I can't do backspace anymore because of that workaround. Is there a way to just disable the "double-tap space for period" functionality just for this single EditText? I noticed the address bar in the Google Chrome app seems to disable this functionality and just treats double-tapped space as two spaces.</p>

Poloniex push api
|
<p>I am interested in writing some basic php to interface with the Poloniex push api.</p>
<p>Their website provides the following info:
<a href="https://poloniex.com/support/api/" rel="nofollow">https://poloniex.com/support/api/</a></p>
<p>A php wrapper can be found here:
<a href="http://pastebin.com/iuezwGRZ" rel="nofollow">http://pastebin.com/iuezwGRZ</a></p>
<p>From what i can determine there are three APIs being push, public and trading. The public and trading APIs provide functions that can be passed parameters etc. The push api stumps me totally as i cannot determine how it works.</p>
<p>The first link above states the API pushes live data and different feeds can be subscribed to.</p>
<p>My questions are:
A) How can php receive a live stream of data?
B) How do i subscribe to a feed?</p>
<p>I may have misunderstood the oush api and my apologies in advance if this is the case.</p>
<p>Edit1:
I believe i need a WAMP client to connect to a WAMP router such as Minion.

Get list of tags with Javascript Use API
|
<p>I am using AEM 6.1 and need to populate a list of filters dynamically based on the list of tags that are available. The tags are nested so that there is a region tag, then country tags nested inside of it, and then city tags nested inside their countries. I need to retrieve the region and all of its children, I've attempted to use an ajax call to return them but it only seems to return me the top level node and none of the children. There doesn't seem to be much information regarding the JS Use API's interaction with the Tag Manager. Really thankful for any information or links that can point me in the right direction.</p>

React Native - What does pressRetentionOffset do?
|
<p>This is what the <a href="https://facebook.github.io/react-native/docs/touchablewithoutfeedback.html#pressretentionoffset" rel="nofollow">documentation says</a> : </p>
<blockquote>
<p><strong>pressRetentionOffset</strong> {top: number, left: number, bottom: number,
right: number} </p>
<p>When the scroll view is disabled, this defines how far your touch may
move off of the button, before deactivating the button. Once deactivated,
try moving it back and you'll see that the button is once again reactivated!
Move it back and forth several times while the scroll view is disabled.
Ensure you pass in a constant to reduce memory allocations.</p>
</blockquote>
<p>But I don't really get it. Could you help me ? </p>

How to get the short display name from a language and region code?

<p>When I use <code>displayNameForKey</code>, for some language, the returned string is too long and different from the native language settings in iOS Settings app. For example:</p>
<pre><code>let locale = NSLocale(localeIdentifier: "zh-Hant")

print(locale.displayNameForKey(key, value: "zh-Hans")!, locale.displayNameForKey(key, value: "zh-Hant-HK")!)

How to set a Django filter to select all
|
<p>I have a view in Django that will read a get request and its parameters and make a query based on the parameters. Currently my view looks like this:</p>
<pre><code>def getInventory(request):
c = request.GET.get('category', '')
g = request.GET.get('gender', '')
s = request.GET.get('size', '')
available = Item.objects.filter(gender=g,category=c,size=s)
data = serializers.serialize('json',available)
return HttpResponse(data,'json')
</code></pre>
<p>Sometimes, though, one of the parameters is not specified. I would like this to result in a value representing 'all' rather than an individual value. Is this possible in the way I've done it? I've tried <code>gender=None</code> but that just results in an empty list.</p>

How to add configuration specific cmake generator expressions to add_custom_target
|
<p>I'm trying to persuade cmake to add a custom target which builds a precompiled header on Visual Studio (note: please do not suggest I used a custom build step instead, I specifically need a build <strong>target</strong> which builds a precompiled header). Note that you cannot simply add CMAKE_CXX_FLAGS_${CMAKE_BUILD_TYPE} during the configuration stage as that won't work in generated .vcxproj's where the user can change the build configuration, so I need to somehow tell cmake in its build stage to output the right stuff for each possible configuration i.e. the appropriate configuration's CMAKE_CXX_FLAGS and CMAKE_CXX_FLAGS_$<CMAKE_BUILD_TYPE></p>
<p>I'm very nearly there with this solution, except for one problem I'm asking for help with:</p>
<pre><code># Adds a custom target which generates a precompiled header
function(add_precompiled_header outvar headerpath)
get_filename_component(header "${headerpath}" NAME)
set(pchpath ${CMAKE_CURRENT_BINARY_DIR}/${header}.dir/${CMAKE_CFG_INTDIR}/${header}.pch)
set(flags ${CMAKE_CXX_FLAGS})
separate_arguments(flags)
set(flags ${flags}
$<$<CONFIG:Debug>:${CMAKE_CXX_FLAGS_DEBUG}>
$<$<CONFIG:Release>:${CMAKE_CXX_FLAGS_RELEASE}>
$<$<CONFIG:RelWithDebInfo>:${CMAKE_CXX_FLAGS_RELWITHDEBINFO}>
$<$<CONFIG:MinSizeRel>:${CMAKE_CXX_FLAGS_MINSIZEREL}>
)
if(MSVC)
add_custom_target(${outvar}
COMMAND ${CMAKE_COMMAND} -E make_directory "${CMAKE_CURRENT_BINARY_DIR}/${header}.dir/${CMAKE_CFG_INTDIR}"
COMMAND ${CMAKE_CXX_COMPILER} /c ${flags} /Fp"${pchpath}" /Yc"${header}" /Tp"${CMAKE_CURRENT_SOURCE_DIR}/${headerpath}"
COMMENT "Precompiling header ${headerpath} ..."
SOURCES "${headerpath}"
)
endif()
endfunction()
</code></pre>
<p>This very nearly works where the correct flags for each build configuration have been expanded into their respective command stanzas in the .vcxproj file:</p>
<pre class="lang-xml prettyprint-override"><code><Command Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">setlocal
"G:\Program Files\CMake\bin\cmake.exe" -E make_directory G:/boost.afio/cmake/afio.hpp.dir/$(Configuration)
if %errorlevel% neq 0 goto :cmEnd
"G:\Program Files\Microsoft Visual Studio 14.0\VC\bin\cl.exe" /c /DWIN32 /D_WINDOWS /W3 /GR /EHsc "/MD /O2 /Ob2 /D NDEBUG" /Fp"G:/boost.afio/cmake/afio.hpp.dir/$(Configuration)/afio.hpp.pch" /Yc"afio.hpp" /Tp"G:/boost.afio/include/boost/afio/afio.hpp"
if %errorlevel% neq 0 goto :cmEnd
:cmEnd
endlocal &amp; call :cmErrorLevel %errorlevel% &amp; goto :cmDone
:cmErrorLevel
exit /b %1
:cmDone
if %errorlevel% neq 0 goto :VCEnd
</Command>
</code></pre>
<p>The problem is that the generator <code>$<$<CONFIG:Release>:${CMAKE_CXX_FLAGS_RELEASE}></code> due to containing spaces expands into the quoted string <code>"/MD /O2 /Ob2 /D NDEBUG"</code> and this of course causes the compiler to complain loudly.</p>
<p>What I need therefore is either one of:</p>
<ol>
<li>Some method of telling cmake generator expressions to not expand content containing a space into a quoted string.</li>
</ol>
<p>OR</p>
<ol start="2">
<li>Some other method of expanding CMAKE_CXX_FLAGS_${CMAKE_BUILD_TYPE} into each of the configuration specific sections for an add_custom_target.</li>
</ol>
<p>Many thanks in advance.</p>
<p><strong>Edit:</strong> Based on Tsyvarev's answer below, I came up with this:</p>
<pre><code># Add generator expressions to appendvar expanding at build time any remaining parameters
# if the build configuration is config
function(expand_at_build_if_config config appendvar)
set(ret ${${appendvar}})
set(items ${ARGV})
list(REMOVE_AT items 0 1)
separate_arguments(items)
foreach(item ${items})
list(APPEND ret $<$<CONFIG:${config}>:${item}>)
endforeach()
set(${appendvar} ${ret} PARENT_SCOPE)
endfunction()
</code></pre>
<p>This is working well. Many thanks to Tsyvarev!</p>
<p><strong>Edit 2</strong>: It turns out cmake has undocumented support for precompiled header generation at least for MSVC. Take a look at the <code>add_precompiled_header()</code> function in <a href="https://github.com/ned14/boost-lite/blob/master/cmake/BoostLitePrecompiledHeader.cmake" rel="nofollow">https://github.com/ned14/boost-lite/blob/master/cmake/BoostLitePrecompiledHeader.cmake</a>, all you need to do is supply the <code>/Yc</code> flag to an OBJECT type library and voila, the Visual Studio generator does the right thing, correct .vcxproj XML stanzas and all.</p>

Edge Browser - iframe.document.open not working
|
<p>We have some functionality for exporting data to an excel file.
When the 'export' button is clicked, some client-side javascript is called, firstly checking the client browser version, and based on this, deciding which way to render the excel document.
It is working in Chrome & Firefox & IE11 when tested locally.
However, when I remotely test using a windows 10 machine running Edge browser, the excel is not rendered.</p>
<p>I might add that my local machine is a Win7 machine and Im running VS2012 and IE11. The remote machine is Win10 with Edge, hence the need to test remotely.
I've tried the emulation in IE11 F12 dev tools but cant replicate the Edge error there.</p>
<p>An error of 'undefined or null reference' is thrown for 'open' when using the following code:</p>
<pre><code>excelIFrame.document.open("txt/html", "replace");
excelIFrame.document.write(sHTML);
excelIFrame.document.close();
excelIFrame.focus();
excelIFrame.document.execCommand("SaveAs", true, "Spreadsheet.xls");
</code></pre>
<p>The iframe exists in the html and is not added dynamically.</p>
<pre><code><iframe id="excelIFrame" style="display:none"></iframe>
</code></pre>
<p>I have tried the following possible solutions to get this working, to no avail - </p>
<p><strong>Possible Solution 1:</strong> Same 'undefined or null reference error when assigning the document to a temp var
</p>
<pre><code>var doc = excelIFrame.document;
doc.open("txt/html", "replace");
doc.write(sHTML);
doc.close();
doc.focus();
doc.execCommand("SaveAs", true, "Spreadsheet.xls");
</code></pre>
<p><strong>Possible Solution 2:</strong> Using the contentWindow property of the iFrame. No error thrown, it just opens 'about:blank' containing no content.</p>
<pre><code>excelIFrame.contentWindow.contents = sHTML;
excelIFrame.src = 'javascript:window["contents"]';
</code></pre>
<p>Totally at a loss with this at this stage.
The page is an angularJS web page.
From reading up on it, I'm aware the document.open is problematic in edge when using iframes. But the following link <a href="https://connect.microsoft.com/IE/feedback/details/1822924/in-an-iframe-document-open-fails-whereas-var-doc-document-doc-open-succeeds" rel="nofollow">document.open fails in an iframe</a> I felt would solve the problem.
Any thoughts or suggestions greatly appreciated.</p>

Assembly- Calling function inside another i.e nested functions
|
<p><br>
I try to call windows function inside my custom assembly function<br>
The pseudocode would be something like:<br></p>
<pre><code>MYFUNC
PUSH EBP
PUSH WINDOWSFUNCTIONPARAMETER
CALL [IMPORTEDWINDOWSFUNCTION]
POP EBP
RET
</code></pre>
<p>So I know its safe to leave this like this if I call only one function inside,<br>
because thie stack will be restored anyway.
<br>
The problem is- why can't i add esp, 0x04 after this? - The app crashes<br>
Im not sure if i even need to do this but imo its safer to do it after function<br>
calls, and somehow i cant get this working inside a function<br>
I'm gratefull for any help :)<br></p>

Android Facebook Login is not working

<p>I am developing an Android app that uses Facebook login. This is my first Facebook login integration in Android. I am having a trouble with integrating facebook login to my app because nothing is shown login is success or not in my callback.</p>
<p>I generated Facebook hash key from debug sign key and set the credentials in Facebook developer settings as below.</p>
<p><a href="https://i.stack.imgur.com/MOK8J.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MOK8J.png" alt="enter image description here"></a></p>
<p>In class name I set com.mmfashionnetwork.ptn.www.mmfashion.LoginActivity That is Login Activity where facebook login button and callback functions exist. My default activity is MainActivity. And facebook app is test mode.</p>
<p>This is my login activity and call back functions</p>
<pre><code>public class LoginActivity extends AppCompatActivity {
private EditText tfEmail;
private EditText tfPassword;
private Button btnLogin;
private ProgressDialog loadingDialog;
private TextView tvForgetPassword;
private TextView tvCreateAccount;
private TextView tvTitle;
private Config config;
private LoginButton btnFbLogin;
private CallbackManager callbackManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
//other steps
setUpFbLoginBtn();
}
private void setUpFbLoginBtn()
{
callbackManager = CallbackManager.Factory.create();
LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Toast.makeText(getBaseContext(),"Success",Toast.LENGTH_SHORT).show();
}
@Override
public void onCancel() {
Toast.makeText(getBaseContext(),"Canceled",Toast.LENGTH_SHORT).show();
}
@Override
public void onError(FacebookException error) {
Toast.makeText(getBaseContext(),"Error",Toast.LENGTH_SHORT).show();
}
});
}
}
</code></pre>
<p>I also set required credentials in Android manifest file. The problem is callback functions are not get called. As you can see I am toasting message in callback according to state. If I try to login clicking Facebook login button. I was redirect to Facebook as in screenshot.</p>
<p><a href="https://i.stack.imgur.com/Cp8YD.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Cp8YD.png" alt="enter image description here"></a></p>
<p>When I click ok, no callback function is called. Current screenshot saying already authorized. But when I logged in for the first time, it is not showing any message when I was redirected to my app Login Activity as well. How can I retrieved data after logging in? In developer settings, I must set login activity class or main activity class? I tried setting both alternate. Both gave me the same result.</p>

Java HTTP Request on VPN only website
|
<p>I am trying to build a website parser for one of our internal websites (accessible only from the company network - we get on the network through Cisco AnyConnect VPN). </p>
<p>I can access the site fine in any browser, but not using HTTP requests. Windows network and sharing center shows that I have two active networks:</p>
<ol>
<li>The actual internet connection</li>
<li>The company network (without internet access).</li>
</ol>
<p>Default HTTP client gets time out as I suppose it makes a request using the actual internet connection (and the website is not accessible to public), but using this code:</p>
<pre><code>HttpParams params = httpClient.getParams();
params.setParameter(ConnRoutePNames.LOCAL_ADDRESS, InetAddress.getByName("10.x.x.x"));
</code></pre>
<p>I get the following error: </p>
<blockquote>
<p>I/O exception caught when connectiong to /10.x.x.x -> {s} -> <a href="https://zzz.com:443" rel="nofollow">https://zzz.com:443</a>: Network is unreachable: connect</p>
</blockquote>
<p>Also, might be a stupid test but I have done a HTTP request to a "what is my ip" site and the IP is shown as my Wifi IP not the IP through VPN (which I get when I open browser and browse to a "what is my ip" website). Same thing (wrong IP) when I try this using a gui-less browser (Jaunt or HTMLUnit).</p>
<p>Please advise if any fixes for this.</p>

How to get Match Groups in ruby like Rubular without spliting the string
|
<p>How does Rubular (<a href="http://rubular.com/r/iJ1eJ1zpHs" rel="nofollow">Example</a>) get the match groups?</p>
<pre><code>/regex(?<named> .*)/.match('some long string')
</code></pre>
<p><a href="http://ruby-doc.org/core-2.2.0/String.html#method-i-match" rel="nofollow">match</a> method (in example) only returns the first match.</p>
<p><a href="http://ruby-doc.org/core-2.2.0/String.html#method-i-scan" rel="nofollow">scan</a> method returns an array without named captures. </p>
<p>What is the best way to get an array of named captures (no splitting)?</p>

onClick in Expandable RecyclerView (using bignerdranch library)
|
<p>In the project I'm working, I get a bunch of "Projects"(parent) with "Issues" (child). As I have to show it in a list, I used RecyclerView to do it. To achieve it I used BigNerdRanch library (<a href="https://github.com/bignerdranch/expandable-recycler-view" rel="nofollow">https://github.com/bignerdranch/expandable-recycler-view</a>)</p>
<p>The problem come's that I need to click on Child to take all the information of the issue and send it to another activity.</p>
<p>The library don't have any method to handle the child click, so I tried to implement a work around and worked (I think is ok..), but here I'm blocked. I don't know how to take the clicked child to launch the activity with the necessary info.</p>
<p>Here is the ProjectAdapter:</p>
<pre><code>public class ProjectAdapter extends ExpandableRecyclerAdapter<ProjectViewHolder, IssueViewHolder> {
private LayoutInflater mInflator;
private Context appContext ;
public ProjectAdapter(Context context, @NonNull List<? extends ParentListItem> parentItemList) {
super(parentItemList);
this.mInflator = LayoutInflater.from(context);
this.appContext = context;
}
@Override
public ProjectViewHolder onCreateParentViewHolder(ViewGroup parentViewGroup) {
View projectView = mInflator.inflate(R.layout.jira_project, parentViewGroup, false);
return new ProjectViewHolder(projectView);
}
@Override
public IssueViewHolder onCreateChildViewHolder(ViewGroup childViewGroup) {
View issueView = mInflator.inflate(R.layout.jira_issue, childViewGroup, false);
return new IssueViewHolder(issueView,this.appContext);
}
@Override
public void onBindParentViewHolder(ProjectViewHolder projectViewHolder, int position, ParentListItem parentListItem) {
Project project = (Project) parentListItem;
projectViewHolder.bind(project);
}
@Override
public void onBindChildViewHolder(IssueViewHolder issueViewHolder, int position, Object childListItem) {
Issue issue = (Issue) childListItem;
issueViewHolder.bind(issue);
}
}
</code></pre>
<p>IssueViewHolder (Child):</p>
<pre><code>public class IssueViewHolder extends ChildViewHolder{
private TextView mIssueTextView; // contendra de momento el "summary" del issue
private Context appContext;
public IssueViewHolder(View itemView, final Context appContext) {
super(itemView);
this.appContext = appContext;
this.mIssueTextView = (TextView) itemView.findViewById(R.id.jir_issue_name);
this.mIssueTextView.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
Log.d("JIRA", "CLICk CHILD");
Toast.makeText(appContext, "CHILD #"+getAdapterPosition() +"\n CHILD##"+getPosition(), Toast.LENGTH_LONG).show();
}
});
}
public void bind(Issue issue){
mIssueTextView.setText(issue.getKey());
}
}
</code></pre>
<p>As I said,I'm stucked on How to get the child information.</p>
<p>How can I solve it?</p>

MongoDB References Not Saving (Mongoose)
|
<p>So I have encountered a strange problem that has been driving me crazy. I have a schema for Stores which represent storefronts that carry the products of certain Manufacturers which I also have a schema for. One of the properties of the Store schema is an array of Manufacturer objects referenced by ObjectId.</p>
<p>Basically, what I want to accomplish is that when a new Store document is created, I want to go through all of the existing Manufacturer documents, and add the <code>_id</code> property of each one to the reference array in the Store document.</p>
<p>The strangest thing is, that after I call the <code>.save()</code> method on the newly created Store model after pushing all the <code>_id</code>'s onto the array, the debugging print out shows that the result saved exactly how I want it. However, when I go to make a cURL call to pull the record from my database, the manufacturers array is completely empty and none of the ObjectId's become populated with their reference.</p>
<p>I have no idea where to go from here, can anybody help?</p>
<p>Thanks</p>

Jboss - handshake failure - client connection using TLSv1.1 instead of TLSv1.2

<p>I have a jboss version Version 6.3.0.GA , using java version 1.7.0_71
My collegues on remote server changes allowed TLS protocol from 1.1 to 1.2, and now i have to update my client (deployed in jboss).

<p>Even after below change has been applied</p>
<p>1 - updated the "standalone.xml" with below values</p>
<pre><code><system-properties>

</system-properties>
</code></pre>
<p>2 - added below JAVA Options to server start:</p>
<pre><code>-Djavax.net.debug=all -Ddeployment.security.TLSv1.2=true -Ddeployment.security.TLSv1.2=true -Ddeployment.security.TLSv1=false -Dhttps.protocols=TLSv1.2
</code></pre>
<p>3 - Changed graphically the protocols in java console
<a href="http://i.stack.imgur.com/moJhq.png" rel="nofollow">JDK control panel</a></p>
<p>but nothing handshake still exists.
I suppose that the error is on "Client Hello" that still use TLSv1 instead of 1.2 .
Do youhave any suggestion to force this value?

Angular js application shows blank white page on ios browsers, safari and chrome both. Works fine on windows desktop browsers

<p>I have one redhat cloud application which front-end developed in Angular.js 1.5.5, it works perfectly fine on windows desktop and android device browsers where only on ios mobile browsers chrome or safari it shows blank white page. When I put sample loading text under body tag I was able to see that but nothing rendered except loadig text. To serve static content it has Node-Hapi.js server which has just basic stuff and static folder path.
Below is application url - </p>

Hibernate: Repeated column in mapping for entity

<p>This is the structure that I'm trying to map:</p>
<p><strong>TABLE A</strong></p>

<p><strong>TABLE B</strong></p>
<p>col0 (PK) |colA (PK) | colC (PK) | ColD</p>
<p><strong>TABLE C</strong> </p>
<p>col0 (PK) | colA (PK) | colC (PK) | ColE (PK) | ColF</p>
<p>I have a problem on the third table (Table C). The exception thrown is </p>
<blockquote>
<p>org.hibernate.MappingException: Repeated column in mapping for entity: TableC column: colA (should be mapped with insert="false" update="false")</p>
</blockquote>
<p>Table C:
</p>
<pre><code>@Entity
@Table(name="TableC")
public class TableC implements Serializable{
@EmbeddedId
private TableCId tableCId;
@MapsId("tableBId")

@JoinColumn(name="colC", referencedColumnName="colC"),
@JoinColumn(name="colA", referencedColumnName="colA")

<p>Here I defined the TableCId
</p>
<pre><code> @Embeddable
public static class TableCId implements Serializable{

Escaping exclamation marks required in replace string but not in search string (substring replacement with delayed expansion on)?
|
<p>Supposing one wants to replace certain substrings by exclamation marks using the <a href="http://ss64.com/nt/syntax-replace.html" rel="nofollow noreferrer">substring replacement</a> syntax while <a href="http://ss64.com/nt/delayedexpansion.html" rel="nofollow noreferrer">delayed expansion</a> is enabled, they have to use immediate (normal) expansion, because the parser cannot distinguish between <code>!</code>s for expansion and literal ones.</p>
<p>However, why does one have to escape exclamation marks in the replacement string? And why is it not necessary and even disruptive when exclamation marks in the search string are escaped?</p>
<p>The following script replaces <code>!</code>s in a string by <code>`</code> and in reverse order afterwards, so I expect the result to be equal to the initial string (which must not contain any back-ticks on its own of course):</p>
<pre><code>@echo off
setlocal EnableExtensions DisableDelayedExpansion
rem This is the test string:
set "STRING=string!with!exclamation!marks!"
set "DELOFF=%STRING%"
set "DELOFF=%DELOFF:!=`%"
set "DELOFF=%DELOFF:`=!%"
setlocal EnableDelayedExpansion
set "DELEXP=!STRING!"
set "DELEXP=%DELEXP:!=`%"
set "DELEXP=%DELEXP:`=!%"
echo(original string: !STRING!
echo(normal expansion: !DELOFF!
echo(delayed expansion: !DELEXP!
endlocal
endlocal
exit /B
</code></pre>
<p>This result is definitely not what I want, the last string is different:</p>
<blockquote>
<pre><code>original string: string!with!exclamation!marks!
normal expansion: string!with!exclamation!marks!
delayed expansion: stringexclamation
</code></pre>
</blockquote>
<p>As soon as take the line...:</p>
<pre><code>set "DELEXP=%DELEXP:`=!%"
</code></pre>
<p>....and replace the <code>!</code> by <code>^!</code> there, hence escaping the exclamation mark in the replace string, the result is exactly what I expect:</p>
<blockquote>
<pre><code>original string: string!with!exclamation!marks!
normal expansion: string!with!exclamation!marks!
delayed expansion: string!with!exclamation!marks!
</code></pre>
</blockquote>
<p>When I try other escaping combinations though (escape the exclamation mark in both the replace and the search string, or in the latter only), the result is again the aforementioned unwanted one.</p>
<p>I walked through the post <a href="https://stackoverflow.com/q/4094699">How does the Windows Command Interpreter (CMD.EXE) parse scripts?</a> but I could not find an explanation to that behaviour, because I learned the normal (or immediate, percent) expansion is accomplished long before delayed expansion occurs and any exclamation marks are even recognised. Also caret recognition and escaping seems to happen afterwards. In addition, there are even quotation marks around the strings that usualy hide carets from the parser.</p>

Node-Red: Create server and share input
|
<p>I'm trying to create a new node for Node-Red. Basically it is a udp listening socket that shall be established via a config node and which shall pass all incoming messages to dedicated nodes for processing.
This is the basic what I have:</p>
<pre><code>function udpServer(n) {
RED.nodes.createNode(this, n);
this.addr = n.host;
this.port = n.port;
var node = this;
var socket = dgram.createSocket('udp4');
socket.on('listening', function () {
var address = socket.address();
logInfo('UDP Server listening on ' + address.address + ":" + address.port);
});
socket.on('message', function (message, remote) {
var bb = new ByteBuffer.fromBinary(message,1,0);
var CoEdata = decodeCoE(bb);
if (CoEdata.type == 'digital') { //handle digital output
// pass to digital handling node
}
else if (CoEdata.type == 'analogue'){ //handle analogue output
// pass to analogue handling node
}
});
socket.on("error", function (err) {
logError("Socket error: " + err);
socket.close();
});
socket.bind({
address: node.addr,
port: node.port,
exclusive: true
});
node.on("close", function(done) {
socket.close();
});
}
RED.nodes.registerType("myServernode", udpServer);
</code></pre>
<p>For the processing node:</p>
<pre><code>function ProcessAnalog(n) {
RED.nodes.createNode(this, n);
var node = this;
this.serverConfig = RED.nodes.getNode(this.server);
this.channel = n.channel;
// how do I get the server's message here?
}
RED.nodes.registerType("process-analogue-in", ProcessAnalog);
</code></pre>
<p>I can't figure out how to pass the messages that the socket receives to a variable number of processing nodes, i.e. multiple processing nodes shall share on server instance.</p>
<p>==== EDIT for more clarity =====</p>
<p>I want to develop a new set of nodes:</p>
<p><em>One Server Node:</em></p>
<ul>
<li>Uses a <a href="http://nodered.org/docs/creating-nodes/config-nodes" rel="nofollow">config-node</a> to create an UDP listening socket</li>
<li>Managing the socket connection (close events, error etc) </li>
<li>Receives data packages with one to many channels of different data</li>
</ul>
<p><em>One to many processing nodes</em></p>
<ul>
<li>The processing nodes shall share the same connection that the Server Node has established</li>
<li>The processing nodes shall handle the messages that the server is emitting</li>
<li>Possibly the Node-Red flow would use as many processing Nodes as there are channels in the server's data package</li>
</ul>
<p>To quote the Node-Red documentation on config-nodes:</p>
<blockquote>
<p>A common use of config nodes is to represent a shared connection to a
remote system. In that instance, the config node may also be
responsible for <strong>creating the connection and making it available</strong> to the
nodes that use the config node. In such cases, the config node should
also handle the close event to disconnect when the node is stopped.</p>
</blockquote>
<p>As far as I understood this, I make the connection available via <code>this.serverConfig = RED.nodes.getNode(this.server);</code> but I cannot figure out how to pass data, which is received by this connection, to the node that is using this connection.</p>

Keep-Alive http header with timeout not used by google, stackoverflow, etc?
|
<p>I started reading about Keep-Alive and was thinking about adding it to my webserver but as I traced <a href="http://google.com" rel="nofollow">http://google.com</a> and <a href="http://stackoverflow.com">http://stackoverflow.com</a>, I noticed they are not sending this header at all back to the clients (with a timeout that is).</p>
<p>Why is that? I would think normally you want to kill connections that have been idle for more than 20 seconds or so. I was actually curious what other websites were using. Perhaps they do timeout the idle connection eventually but just don't tell the clients they are going to do that(which seems odd).</p>
<p>I did a "telnet google.com 80" and waited about 2 minutes and it never timed out and then I issued a "GET / HTTP/1.1" and waited some more than typed in a bunch of random garbage over and over(not sure they limit the header size either so you 'could' OOM their servers I think). I finally hit enter twice and got back a 200 OK....none of my headers were well-formed but google didn't seem to care(odd).</p>
<p>thanks,
Dean</p>

VBA: Only save the last (The most recent) email attachment in a local folder

Spark Streaming: how to get processing time and scheduling delay by StreamingListener?
|
<p>The offical documentation says we can get the values of processing time by StreamingListener: The progress of a Spark Streaming program can also be monitored using the StreamingListener interface, which allows you to get receiver status and processing times.
<a href="http://spark.apache.org/docs/latest/streaming-programming-guide.html#monitoring-applications" rel="nofollow">http://spark.apache.org/docs/latest/streaming-programming-guide.html#monitoring-applications</a></p>
<p>I know there is some information about the metrics of Spark, but it does not contains the processing time and scheduling delay.
<a href="http://spark.apache.org/docs/latest/monitoring.html#rest-api" rel="nofollow">http://spark.apache.org/docs/latest/monitoring.html#rest-api</a></p>
<p>I read the source code of StreamingListener． It contains a method like this: </p>
<pre><code>def printStats() {
showMillisDistribution("Total delay: ", _.totalDelay)
showMillisDistribution("Processing time: ", _.processingDelay)
}
</code></pre>
<p>I think it is possible to get these metrics but I did not realize it.
I need these metrics for my research. How can I get them? Thanks very very much．</p>

Angular2 Parent Component Not Triggering Event of Child Component
|
<p>I am attempting to create a component that allows the user to select actions to be performed on "tests" using a table interface. Each row of the table is a separate child component with the parent component comprising of the table headers and the child component rows, which are created using <code>*ngFor</code>.</p>
<p>Everything is mostly going well, except I need the checkbox in the header to check all of the child component checkboxes and the select in the header to select all of the child component to equal the chosen option in the header. The checkboxes look like it works (as demoed in the Plunker), but the event handler in the parent component does not get the updated checked value when the header checkbox is checked, but does when the actual row's checkbox is checked. The demo has the checkboxes printing stuff to the console. I would expect the header checkbox to trigger all of the checkbox's 'checked' event and print multiple statements to the console (two lines per table row).</p>
<p>I started putting the pieces in place to handle the header's select changing, but am a little stuck as to how to make a select's option selected when the options are being populated using <code>*ngFor</code>.</p>
<p>I don't know if it matters, but I am using angular2-beta 15 and am trying to stay on this version if possible.</p>
<p>Plunker and code dump are below.</p>
<pre><code>import {Component, EventEmitter, Output, Input} from 'angular2/core'

<td class="center">

Using trailing closure in for-in loop
|
<p>I'm using <code>map()</code> function of array in for-in loop like this:</p>
<pre><code>let numbers = [2, 4, 6, 8, 10]
for doubled in numbers.map { $0 * 2 } // compile error
{
print(doubled)
}
</code></pre>
<p>which produces compile error:</p>
<blockquote>
<p>Use of unresolved identifier 'doubled'</p>
</blockquote>
<p>However, if I put parenthesis for <code>map()</code> function, it works fine. i.e.</p>
<pre><code>for doubled in numbers.map ({ $0 * 2 })
{
print(doubled)
}
</code></pre>
<p>My question is, why wouldn't compiler differentiate code block of trailing function and loop, assuming this is causing the problem?</p>

Angular 2 - Services consuming others services before call a method
|
<p>I've this scenario.</p>
<p>backend.json</p>
<pre><code>{
"devServer": "http://server1/'",
"proServer" : "http://server2/'",
"use" : "devServer"
}
</code></pre>
<p>global.service.ts</p>
<pre><code>import {Injectable} from '@angular/core';
import {Http, HTTP_PROVIDERS, Response, RequestOptions, URLSearchParams} from '@angular/http';
@Injectable()
export class GlobalService {
constructor(private _http: Http){}
getBackendServer(){
return this.server = this._http.get('./backend.json')
.map((res:Response) => res.json())
}
}
</code></pre>
<p>And I've this other service: search.service.ts</p>
<pre><code>import {Injectable} from '@angular/core';
import {Http, HTTP_PROVIDERS, Response, RequestOptions, URLSearchParams} from '@angular/http';
import {GlobalService} from '../services/global.service';
import 'rxjs/add/operator/map';
@Injectable()
export class SearchService {
server;
constructor( private _http: Http, private gs: GlobalService ) {
this.server = gs.getBackendServer().subscribe(
(data) => {
this.server = data[data.use];
},
(err) => {
console.log(err);
}
);
}
DoGeneralSearch(params:Search){
console.log(this.server);
let options = this.buildOptions(params);
return this._http.get(this.server + 'room/search', options)
.map((res:Response) => res.json())
}
}
</code></pre>
<p>What I want to do: Looks obvious: I want to keep the information regarding the URL of the backend server in a JSON file - And the global service should return the server so this can be used in any method of the search service.</p>
<p>The problem is: the DoGeneralSearch() method executes before the global service is capable to resolve the task to read the JSON file and return the result. So, I've a this.server = Subscriber {isUnsubscribed: false, syncErrorValue: null, syncErrorThrown: false, syncErrorThrowable: false, isStopped: false…} instead the result itself.</p>
<p>I need to find some how to prevent the method DoGeneralSearch be executed just after resolved the this.server variable.</p>
<p>Any suggestions ?</p>

SQL Server Agent Job step is not getting executed
|
<p>I have written sql agent job that has 2 steps. First step is executing another job which deletes text file from some location and second step is copying specific file and pasting it to some location. If I execute these two steps independently they execute properly. However when I run it as a job, only first step gets executed , second does not. Job history is shows as Success. So it seems second step is also getting executed but is is not performing any action. Please suggest. </p>

How to force Android Studio to build with updated NDK library, without having to clean and build entire project?
|
<p>How can I force Android Studio to build my app using the the updated NDK shared library (.so) file, without having to clean the entire project first?</p>
<p>There must be some mechanism by which Android Studio can detect that the shared library has been updated and to use the latest one. If I do a Build->Clean Project and then do a Run->Run 'app' it will use the new version of the library, but it will also have to do a lot of work that is unnecessary, since none of the java source has changed. Even a Run->Clean and Rerun'app' won't use the new library.(!!!)</p>

k-means++ vs random for initial centers
|
<p>I've seen that in many K-means implementations, like <a href="http://www.vlfeat.org/api/kmeans.html" rel="nofollow">VLFeat k-means</a> or <a href="http://docs.opencv.org/3.0-beta/doc/py_tutorials/py_ml/py_kmeans/py_kmeans_opencv/py_kmeans_opencv.html" rel="nofollow">OpenCV k-means</a>, there are essentially 2 methods for choosing starting centroids:</p>

<li>Randomly</li>
<li>Following the <a href="https://en.wikipedia.org/wiki/K-means%2B%2B" rel="nofollow">K-Means++</a> algorithm</li>
</ol>
<p>However, I didn't get in which cases one is better of the other, especially because the starting method is considered important. Can you help me understanding this point?</p>

How to get Drools (Kie Session) running in a Netbeans Web-Project (No Maven)?
|
<p>For several days I'm trying to run Drools in Netbeans but it just doesn't work like I want it to. I even tried to get it working as a maven project but that didn't work as well. I describe what I do to create the project, hopefully someone can give me a hint.</p>
<p><strong>First of i need it to work without maven because I'm restricted to not use it.</strong> But before I put it in the real project I want to test it.</p>
<p>So first I create a new project </p>
<ol>
<li>File>New Project.. Wizard</li>
<li>Chose "Java Web" Categorie and use Projecttype "Webapplication"</li>
<li>Selection a tomcat 8 webserver and Java EE 7 Web</li>
<li>No Frameworks for now (later hibernate)</li>
<li><p>Create lib folder in project and putting following jars in it:</p>
<ul>
<li>drools-compiler-6.4.0.Final.jar</li>
<li>drools-core-6.4.0.Final.jar</li>
<li>drools-decisiontables-6.4.0.Final.jar</li>
<li>drools-jsr94-6.4.0.Final.jar</li>
<li>drools-reteoo-6.4.0.Final.jar</li>
<li>knowledge-api-6.4.0.Final.jar</li>
<li>kie-api-6.4.0.Final.jar</li>
<li>kie-internal-6.4.0.Final.jar</li>
<li>kie-ci-6.4.0.Final.jar</li>
<li>mvel2-2.2.6.Final.jar</li>
<li>antlr-runtime-3.5.Final.jar</li>
</ul></li>
</ol>
<p>With this Setup I create classes (both in package: Drools)
<strong>DroolsMain</strong> (test without webserver and gui for faster debugging)</p>
<pre><code>public class DroolsMain {
private static KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
private static Collection<KnowledgePackage> pkgs;
private static KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
private static StatefulKnowledgeSession ksession;
public static void main(final String[] args) {
init();
initMessageObject();
fireRules();
}
private static void init() {
String myRule = "import Drools.Message rule \"Hello World 2\" when message:Message (type==\"Test\") then System.out.println(\"Test, Drools!\"); end";
Resource myResource = ResourceFactory.newReaderResource((Reader) new StringReader(myRule));
kbuilder.add(myResource, ResourceType.DRL);
if(kbuilder.hasErrors()) {
System.out.println(kbuilder.getErrors().toString());
throw new RuntimeException("unable to compile dlr");
}
pkgs = kbuilder.getKnowledgePackages();
kbase.addKnowledgePackages(pkgs);
ksession = kbase.newStatefulKnowledgeSession();
}
private static void fireRules() {
ksession.fireAllRules();
}
private static void initMessageObject() {
Message msg = new Message();
msg.setType("Test");
ksession.insert(msg);
}
}
</code></pre>
<p>and the above used <strong>Message</strong> class</p>
<pre><code>public class Message {
private String type;
private String message;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
</code></pre>
<p>I now can run that code and have a the message returned.</p>
<p>Now i wanted to try it with Kie...</p>
<p>i just comment the methods in <strong>DroolsMain</strong> main() method.
and put a Kie method in like current Drools documentation p. 172-174 there:</p>
<pre><code>private static void kieTest() {
KieServices kieServices = KieServices.Factory.get();
KieContainer kContainer = kieServices.getKieClasspathContainer();
StatelessKieSession kSession = kContainer.newStatelessKieSession();
Applicant bob = new Applicant("Mr. Bob", 16);
//assertTrue(bob.isValid());
kSession.execute(bob);
//assertFalse(bob.isValid());
}
</code></pre>
<p>I didn't put the Applicant.class in here becaus its just a bean with 3 attributes.
Also I create DRL <strong>applicant.drl</strong> file:</p>
<pre><code>package Drools "Is of valid age"
import Drools.Applicant
when
$a : Applicant(age < 18)
then
$a.setValid(false);
end;
</code></pre>
<p>So this obviously does not work because Kie has maven dependencies so i tried this:
1. Add directories:
- DroolsTest/resources/
- DroolsTest/resources/META-INF
- DroolsTest/resources/META-INF/maven
- DroolsTest/resources/Drools
2. Create DroolsTest/resources/META-INFkmodule.xml</p>
<p>Content:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<kmodule xmlns="http://www.drools.org/xsd/kmodule">
<kbase name="Drools" packages="Drools">
<ksession name="ksession-drools" />
</kbase>
</kmodule>
</code></pre>
<ol start="3">
<li><p>Create DroolsTest/resources/META-INF/maven/pom.properties
Content: (groupId my package name), (artifactId my project name)</p>
<p>groupId=Drools
artifactId=DroolsTest

<li>put drl file here: DroolsTest/resources/Drools/applicant.drl</li>
</ol>
<p>Compiling this throws a RuntimeException:</p>

Android view zip file without extracting
|
<p>I am trying to get the contents of a zip file without extracting it. I am using ZipFile to get the entries. But what I observed is it is giving all the files in zip folder in file format like system/app.apk instead of giving system as a directory(like how file.listFiles() gives). How do i get the files in a directory structure format? </p>
<p><strong>Zip structure:</strong></p>
<pre><code> ZipFolder.zip - system (folder) -> app.apk(file)
- meta (folder) -> manifest(folder) -> new.apk (file)
</code></pre>
<p>Code:</p>
<pre><code> ZipFile zipFile = new ZipFile(mPath);
Enumeration<? extends ZipEntry> entries = zipFile.entries();
while(entries.hasMoreElements()) {
// below code returns system/app.apk and meta/manifest/new.apk
// instead of system,meta folders
ZipEntry entry = entries.nextElement();
String fileName = entry.getName();
boolean isDirectory = entry.isDirectory(); //returns false
}
</code></pre>

how to declare that a given class implements an interface in Facebook Flow?
|
<p>I have the following code using Flow:</p>
<pre><code>// @flow
'use strict';
import assert from 'assert';
declare interface IPoint {
x: number;
y: number;
distanceTo(other: IPoint): number;
}
class Point {
x: number;
y: number;
distanceTo(a: IPoint): number {
return distance(this, a);
}
constructor(x: number, y: number) {
this.x = x;
this.y = y;
}
}
function distance(p1: IPoint, p2: IPoint): number {
function sq(x: number): number {
return x*x;
}
return Math.sqrt( sq(p2.x-p1.x)+sq(p2.y-p1.y) );
}
assert(distance ( new Point(0,0), new Point(3,4))===5);
// distance ( new Point(3,3), 3); // Flow complains, as expected
assert((new Point(0,1)).distanceTo(new Point(3,5))===5);
// (new Point(0,1)).distanceTo(3); // Flow complains as expected
</code></pre>
<p>Running <code>npm run flow</code> yields no complains as expected, whereas the commented-out lines give rise to warnings (again, as expected).</p>
<p>So all's well with the world except that I don't know how to make it explicit at the point where class <code>Point</code> is defined that it is "implementing" interface <code>IPoint</code>. Is there a way to do so or is it not idiomatic?</p>

Why is internet explorer so bad to develop for?
|
<p>Why do almost all developers hate developing for Internet Explorer? Recently a client asked for IE 11 support on a new project, and one of the developers basically refused. My goal is to understand her point of view better. What additional development challenges does supporting IE create? Are there sacrifices to the user experience if we try to support IE 11? Or are there just a million little unpredictable problems that vary from project to project?</p>

Setting "flags" between threads in Java
|
<p>I have a class which connects to a server as below.</p>
<pre><code>@Override
public void run() {
while (running) {
try {
msgHandler.log("Connecting to " + host + ":" + port);
Socket s = new Socket(host, port);
if (s.isConnected() && !s.isClosed()) {
msgHandler.connectionInit(s);
}
BufferedInputStream input = new BufferedInputStream(s.getInputStream());
}
}
</code></pre>
<p>The consumer which is the msgHandler, frequently polls the socket if a connection ever goes down as below.</p>
<pre><code>@Override
public void connectionInit(Socket s) throws IOException {
logger.info("Connected to AWW Service on " + configuration.getAwwHost() + ":" + configuration.getAwwPort());
output = new BufferedOutputStream(s.getOutputStream());
connector.componentReady();
Timer t = new Timer();
t.schedule(new TimerTask() {
@Override
public void run() {
try {
pollServer();
} catch (IOException e) {
// SOCKET GETS BROKEN HERE
}
}
}, 0, 25000);
}
</code></pre>
<p>Question is, how can i communicate from the exception i get when the socket connection gets broken back to the run() thread, so it can try to reinitialize the socket and the input stream?</p>
<p>I dont think a notify() or wait() mechanism is appropriate here as wait() will just put the run() thread to sleep.
I was thinking whats the equivalent of setting a flag when the connection gets broken, and the run() thread constantly checks the flag, and when it is set to true, it reinitialize the socket. But i am sure there would be a more efficient multi threading approach native to java for achieving this.</p>

Aurelia router not working when resetting root
|
<p>I want to use aurelia-auth in my app and also have a login page that is completely separate from the rest of the app. I have been following the tutorial at this link: <a href="https://auth0.com/blog/2015/08/05/creating-your-first-aurelia-app-from-authentication-to-calling-an-api/" rel="nofollow">https://auth0.com/blog/2015/08/05/creating-your-first-aurelia-app-from-authentication-to-calling-an-api/</a></p>

pass a method into another method as a parameter but with parameters

return stuff;

How to use locks without causing deadlock in concurrent.futures.ThreadPoolExecutor?
|
<p>I'm processing Jira changelog history data, and due to the large amount of data, and the fact that most of the processing time is I/O based, I figured that an asynchronous approach might work well. </p>
<p>I have a list of all <code>issue_id</code>'s, which I'm feeding into a function that makes a request through the <code>jira-python</code> api, extracts the information into a <code>dict</code>, and then writes it out through a passed in <code>DictWriter</code>. To make it threadsafe I imported a <code>Lock()</code> from the <code>threading</code> module, which I am also passing in. On testing, it seems to get deadlocked at a certain point and just hangs. I noticed in the documentation where it said that if tasks are reliant on one another then they can hang, and I suppose they are due to the lock I'm implementing. How can I prevent this from happening? </p>
<p>Here is my code for reference:</p>
<p>(At this point in the code there is a list called <code>keys</code> with all the issue_id's)</p>
<pre><code>def write_issue_history(
jira_instance: JIRA,
issue_id: str,
writer: DictWriter,
lock: Lock):
logging.debug('Now processing data for issue {}'.format(issue_id))
changelog = jira_instance.issue(issue_id, expand='changelog').changelog
for history in changelog.histories:
created = history.created
for item in history.items:
to_write = dict(issue_id=issue_id)
to_write['date'] = created
to_write['field'] = item.field
to_write['changed_from'] = item.fromString
to_write['changed_to'] = item.toString
clean_data(to_write)
add_etl_fields(to_write)
print(to_write)
with lock:
print('Lock obtained')
writer.writerow(to_write)
if __name__ == '__main__':
with open('outfile.txt', 'w') as outf:
writer = DictWriter(
f=outf,
fieldnames=fieldnames,
delimiter='|',
extrasaction='ignore'
)
writer_lock = Lock()
with ThreadPoolExecutor(max_workers=5) as exec:
for key in keys[:5]:
exec.submit(
write_issue_history,
j,
key,
writer,
writer_lock
)
</code></pre>
<p>EDIT: It's also very possible I'm being throttled by the Jira API.</p>

How do I close a browser window/tab and return control to another tab using Spring MVC?
|
<p>I am using Spring MVC to call a web service. The intent is to get back a PDF in a separate window/tab in the browser if the call is successful, else if there is an error returned to have the error returned to the original window/tab. In the jsp code for the html view, I am setting document.forms[0].target = '_blank'; in the submitAction function to create the second browser window/tab to contain the PDF returned by the web service. This works fine if the web service runs with no errors. If an error is returned with no PDF, when I return the mav in my controller it creates the action submission page in the second window/tab with the error message showing in that window. That is not what I want. If I get an error returned from the service, how can I return the error message to the original window/tab and close the second window/tab that was created by making the target equal to '_blank' in the submitAction function?</p>

RANK records partitioned by a column in series (Vertica SQL)
|
<p>I'm trying to use the Vertica rank analytic function to create a rank column partitioned by a column, but only include records that are in a series. For example the query below produces the output below the query</p>
<pre><code>select when_created, status
from tablea
when_created Status
1/1/2015 ACTIVE
3/1/2015 ACTIVE
4/1/2015 INACTIVE
4/6/2015 INACTIVE
6/7/2015 ACTIVE
10/9/2015 INACTIVE
</code></pre>
<p>I could modify my query to include a rank column which would produce the following output</p>
<pre><code>select
when_created, status, rank() OVER (PARTITION BY status order by when_created) as rnk
from tablea
when_created Status rnk
1/1/2015 ACTIVE 1
3/1/2015 ACTIVE 2
4/1/2015 INACTIVE 1
4/6/2015 INACTIVE 2
6/7/2015 ACTIVE 3
10/9/2015 INACTIVE 3
</code></pre>
<p>However my goal is start over the rank when a series is broken so the desired output is:</p>
<pre><code>when_created Status rnk
1/1/2015 ACTIVE 1
3/1/2015 ACTIVE 2
4/1/2015 INACTIVE 1
4/6/2015 INACTIVE 2
6/7/2015 ACTIVE 1
10/9/2015 INACTIVE 1
</code></pre>
<p>Is there a way to accomplish this using the RANK function or is there another way to do it in vertica sql?</p>
<p>Thanks,
Ben</p>

Transform Names Matrix into Dataframe rows
|
<p>Lets say I have a matrix <code>mat</code> which has both column names and row names:</p>
<pre><code>mat <- matrix(1:25, ncol = 5)
rownames(mat) <- LETTERS[1:5]
colnames(mat) <- LETTERS[6:10]
</code></pre>
<p>^^ Simple and reproducible example to make the following matrix:</p>
<pre><code> F G H I J
A 1 6 11 16 21
B 2 7 12 17 22
C 3 8 13 18 23
D 4 9 14 19 24
E 5 10 15 20 25
</code></pre>
<p>I need to turn this matrix into a data frame that looks like the following:</p>
<pre><code>ROWNAME COLNAME VALUE
A F 1
B F 2
C F 3
......
</code></pre>
<p>Is there a function built in to do this? How would I tackle such a problem.</p>
<p>Also, this matrix would be one of many matrices so there would need to be a <code>Matrix Name</code> column added so that it could parse over multiple matrices and create a data.frame that is actually 4 columns and as many observations as values in all of the matrices combined. If there is a shortcut for any of these steps it would be greatly appreciated.</p>

Bintray response conflict with error code 409

<p>We've an Android Studio project on which we collaborate together.
A colleague has setup a bintray.com to gather there all required libraries within our android Studio project. We both have our accounts there, we've setup our bintray API key and corresponding github username in the <code>gradle.properties</code> file. For him it works fine and he gets the uploaded libraries like <code>test-1.0.0.pom</code>; but I don't.</p>
<p>Instead I get </p>

<p>I unmarshaled it by using this method</p>
<pre><code>youtubeData := YoutubeData{}
if json.Unmarshal(b, &youtubeData); err != nil {
} else {
}
</code></pre>
<p>In which b is the byte data received from Youtube API. I successfully got all data in the byte object as I printed it out to my console, however, once I unmarshaled it and tried to output it on the template by using {{.}}, I received</p>
<pre><code>{youtube#searchListResponse "5g01s4-wS2b4VpScndqCYc5Y-8k/JwGY0TWwWswjZ9LOvemaF5yxsMo" CBQQAA TH { } []}
</code></pre>
<p>All data are unmarshaled except for the data in json object and array which are <em>pageInfo</em> and <em>items</em>. There are simply blank. I believe I exported them all correctly. Are there some additional steps to get the data into slice or struct nested inside another struct in Go when it comes to json unmarshalling?</p>

How to insert string into input field using C# in WPF Webbrowser
|
<p>I have found lots of info on this issue on Stackoverflow, but looks like I'm still missing something. With the Webbrowser I would like to fill in a string into in input field of a certain webpage. By clicking on a button I wish to put some text in the input field.</p>
<p>Here is my code:</p>
<pre><code>using System.Windows.Forms;
</code></pre>
<p>and the function:</p>
<pre><code> private void button2_Click(object sender, RoutedEventArgs e)
{
HtmlDocument doc = (HtmlDocument)webBrowser1.Document;
doc.GetElementsByTagName("input")["username"].SetAttribute("Value", "someString");
}
</code></pre>
<p>The second button handles then the webBbrowser1.Navigate method. </p>
<p>Then I get this error:</p>
<p><em>{"Unable to cast COM object of type 'mshtml.HTMLDocumentClass' to class type 'System.Windows.Forms.HtmlDocument'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface."}</em></p>
<p>Any ideas? Thanks.</p>

Was setTimer deprecated in Swift 3?
|
<p>I am trying to create a CocoaPod for Swift 3. Because CocoaPods uses <a href="https://github.com/Quick/Nimble" rel="noreferrer">Nimble</a> and <a href="https://github.com/Quick/Quick" rel="noreferrer">Quick</a>, and those libraries haven't been updated yet, I forked the repos and am trying to convert them.</p>
<p>In the Nimble project there is a function called with the signature of:</p>
<pre><code>setTimer(start: DispatchTime, interval: UInt64, leeway: UInt64)
</code></pre>
<p>The compiler says <code>Cannot invoke 'setTimer' with an argument list of type '(start: DispatchTime, interval: UInt64, leeway: UInt64)'</code></p>
<pre><code>private let pollLeeway: UInt64 = NSEC_PER_MSEC
let interval = UInt64(pollInterval * Double(NSEC_PER_SEC))
asyncSource.setTimer(start: DispatchTime.now(), interval: interval, leeway: pollLeeway)
</code></pre>
<p>The auto-complete shows all the setTimer methods are deprecated, but from what I <a href="https://github.com/apple/swift-evolution/blob/master/proposals/0088-libdispatch-for-swift3.md" rel="noreferrer">found</a> they shouldn't be.</p>
<p>Is there a replacement?</p>

Spring Integration: the SecurityContext propagation
|
<p>I have some perplexity about the SecurityContext propagation in Spring Integration.</p>
<p>Here is the point of the documentation:</p>
<p><a href="http://docs.spring.io/spring-integration/reference/htmlsingle/#security-context-propagation" rel="nofollow">http://docs.spring.io/spring-integration/reference/htmlsingle/#security-context-propagation</a></p>
<p>My perplexity are the following:</p>
<blockquote>
<p><strong>(1)</strong> To be sure that our interaction with the application is secure,
according to its security system rules, we should supply some security
context with an authentication (principal) object. The Spring
Security project provides a flexible, canonical mechanism to
authenticate our application clients over HTTP, WebSocket or SOAP
protocols (as can be done for any other integration protocol with a
simple Spring Security extension) and it provides a SecurityContext
for further authorization checks on the application objects, such as
message channels. By default, the SecurityContext is tied with the
current Thread's execution state using the
(ThreadLocalSecurityContextHolderStrategy). It is accessed by an AOP
interceptor on secured methods to check if that principal of the
invocation has sufficent permissions to call that method, for example.
<strong>This works well with the current thread</strong>, <strong>but often</strong>, processing logic
<strong>can be performed</strong> on another thread or even on several threads, or on
<strong>to some external system(s)</strong>.</p>
</blockquote>
<p>This means that the SecurityContext (normally) is accessible only for the current Thread. Right?</p>
<p>So, how to make it accessible for another thread of another application (integrated with Spring Integration) ?</p>
<blockquote>
<p><strong>(2)</strong> Standard thread-bound behavior is easy to configure if our application is built on the Spring Integration components and its
message channels. <strong>In this case, the secured objects may be any
service activator or transformer</strong>, secured with a
<code>MethodSecurityInterceptor</code> in their
(see Section 8.8, “Adding Behavior to Endpoints”) or even
<code>MessageChannel</code> (see Section D.2, “Securing channels” above). When
using DirectChannel communication, the SecurityContext is available
automatically, because the downstream flow runs on the current thread.
But in case of the QueueChannel, ExecutorChannel and
PublishSubscribeChannel with an Executor, messages are transferred
from one thread to another (or several) by the nature of those
channels. In order to support such scenarios, <strong>we can either transfer
an Authentication object within the message headers and extract and
authenticate it on the other side before secured object access</strong>.
<strong>Or, we can propagate the SecurityContext to the thread receiving the
transferred message</strong>.</p>
</blockquote>
<p>This means that we have to extract the Principal manually? If yes, how?</p>
<p>Or it's enough to use the propagation aspect, from 4.2 version?</p>
<blockquote>
<p><strong>(3)</strong> Starting with version 4.2 <strong>SecurityContext propagation</strong> has been
introduced. It is implemented as a
<code>SecurityContextPropagationChannelInterceptor</code>, <strong>which can simply be
added to any <code>MessageChannel</code> or configured as a
<code>@GlobalChannelInterceptor</code></strong>. The logic of this interceptor is based on
the SecurityContext extraction from the current thread from the
<code>preSend()</code> method, and its populating to another thread from the
<code>postReceive()</code> (beforeHandle()) method. Actually, this interceptor
is an extension of the more generic
ThreadStatePropagationChannelInterceptor, which wraps the
message-to-send together with the state-to-propagate in an internal
Message extension - MessageWithThreadState, - on one side and
extracts the original message back and state-to-propagate on another.
The ThreadStatePropagationChannelInterceptor can be extended for any
context propagation use-case and
SecurityContextPropagationChannelInterceptor is a good sample on the
matter.</p>
</blockquote>
<p><em>"Starting with version 4.2 SecurityContext propagation has been introduced."</em> => Ok, very well.</p>
<p>But: <em>"It is implemented as a SecurityContextPropagationChannelInterceptor, which can simply be added to any MessageChannel or configured as a @GlobalChannelInterceptor."</em></p>
<p>What does it mean? I have to implement an interceptor that extends "SecurityContextPropagationChannelInterceptor" ?</p>
<p>What I have to "add" in my <code><int:channel></code> configuration?</p>
<p>And if I use <code><int:channel-interceptor></code> (the same of @GlobalChannelInterceptor), it's different from using <code><int:interceptors></code> ?</p>
<p>Other perplexity:</p>
<p><em>"The logic of this interceptor is based on the SecurityContext extraction from the current thread from the preSend() method, and its populating to another thread from the postReceive()
(beforeHandle()) method."</em></p>
<p>But why there are a <em><code>"obtainPropagatingContext"</code></em> method and a <em><code>"populatePropagatedContext"</code></em> method in the <code>SecurityContextPropagationChannelInterceptor</code> class?
Where is made the propagation? In the preSend() / postReceive() methods, or in those two methods?</p>
<p>Furthermore, I tried to propagate the SecurityContext to an external application, without success...</p>
<p>Any explanations about this argument would be appreciated.</p>

How to print to Jenkins' console report the messages from failed asserts?

<p>My FullStack tests run on Jenkins and output nothing on success, otherwise the test name and the failed line. This tells nothing about what went wrong.</p>
<p>Is there a way to print the assertion error message on the Jenkins console?</p>
<p>I have a <code>TestWatcher</code> that already takes a screenshot. Should it also do a <code>System.out.println(e.getMessage())</code>?</p>
<p>I want it to print something like this:</p>
<pre><code>java.lang.AssertionError: Page is listing a different job
Expected: <true>
but: was <false>

links to other AMP pages in an AMP article
|
<p>I have several non-AMP pages within a topic. My non-AMP pages will have links within the body of the article to other non-AMP pages in the same topic. Should the AMP versions of the pages link to the other AMP pages in the same topic or should all links in the articles point to the non-AMP (canonical) versions of the pages? </p>
<pre><code>Using the following link formats for the example:
Non-AMP version: /muffins/blueberry/
AMP version: /muffins/blueberry/amp/
</code></pre>
<p><strong>/muffins/blueberry/</strong> has a link to <strong>/muffins/strawberry/</strong><br>
Should <strong>/muffins/blueberry/amp/</strong> link to <strong>/muffins/strawberry/amp/</strong> or to <strong>/muffins/strawberry/</strong>?</p>
<p>Or said another way, if a visitor comes to your site on an AMP page, do you continue to offer them links to other AMP versions of your pages or should you switch them over to the full pages as soon as possible?</p>

Creating a template in Tableau to make moving between similar excel files smooth
|
<p>I am very new to Tableau and just finished my first sheet/dashboard combination for a set of data.</p>
<p>I now want to be able to open up various other excel workbooks (similarly named headers/sheets etc) and get the same Tableau dashboard (with calculated fields etc) just with the new data.</p>
<p>I can open each workbook one by one and switch data sources between each, but is there a simpler way? Also this doesnt maintain calculated fields which is a necessity!</p>
<p>Thanks</p>

Spring MVC, HashMap as model - how to get value using javascript variable as key in jsp
|
<p>I have a model like this:</p>
<pre><code> @ModelAttribute("availableFonts")
public Map<String, String> getAllAvaliableFonts() {
...
}
</code></pre>
<p>Model is containing font name as a key and css code as a value. Now in jsp I have a javaScript code which should apply css dynamicly to preview font, which looks more/less like this:</p>
<pre><code>var css = '${availableFonts.get("Arial Black")}';
jQuery('#preview').removeClass().addClass(css);
</code></pre>
<p>And it's working good with hardcoded map.get(). Css value is taken from HashMap which is model in my jsp.</p>
<p>But I need this map key as a javaScript variable like:</p>
<pre><code> var key = 'Arial Black';
var css = '${availableFonts.get("' + key + '")}';
jQuery('#preview' + i).removeClass().addClass(css);
</code></pre>
<p>And it's not working. Is it possible to do it in javaScript ?</p>

are `Matchers.hasItem` and `Matchers.contains` the same?

Should I always nest selectors in other selectors when using sass?
|
<p>My question is about nesting in sass or scss. It is a good thing from the readability perspective that we can nest selectors inside another selectors in sass but is it something that we must do? I am a little bit confused because when I run scss-lint, then I'm getting some errors nesting depth. I red a few articles and now I know that we should go deeper than nesting more than 3 rules one inside another. </p>
<p>So I have two questions:</p>
<ol>
<li><p>Is there anything wrong if I will write my rules in sass just like this (without nesting):</p>
<p>.my-class
...</p></li>
</ol>
<p>Instead of writing like that: </p>
<pre><code>header
nav
.myclass
</code></pre>
<ol start="2">
<li>Can you explain why is it necessary to nest in sass and what are the advantages of nesting? I know that it is good for overriding rules, but if I don't need to nest that deep? I will appreciate any answers or even links to some articles explaining my questions in more detail. </li>
</ol>

C# enable/disable network tracing at runtime?
|
<p>In the examples I can find the tracing is enabled via config file, for example </p>
<pre><code> <?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<system.diagnostics>
<sources>
<source name="System.Net" tracemode="includehex" maxdatasize="1024">
<listeners>
<add name="System.Net"/>
</listeners>
</source>
</sources>
<switches>
<add name="System.Net" value="Verbose"/>
</switches>
<sharedListeners>
<add name="System.Net"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="network.log"
/>
</sharedListeners>
<trace autoflush="true" indentsize="4" />
</system.diagnostics>
</configuration>
</code></pre>
<p>But I don't want config file to be shipped with my dll. Moreover I need to be able to enable/disable tracing and change log name "on the fly" in my code.
What I came up with:</p>
<pre><code>FileStream stream = new FileStream("D:\\network1.log", FileMode.OpenOrCreate);
TextWriterTraceListener listener = new TextWriterTraceListener(stream);
Trace.Listeners.Add(listener);
Trace.AutoFlush = true;
TraceSwitch ts = new TraceSwitch("System.Net", ".Net");
ts.Level = TraceLevel.Verbose;
</code></pre>
<p>and it is not logging anything, and I don't know where to add the switch, and if that is correct at all.
The listener works but it don't fetch any data.</p>
<p>I've been reading msdn and this blog post <a href="http://www.codeguru.com/csharp/.net/article.php/c19405/Tracing-in-NET-and-Implementing-Your-Own-Trace-Listeners.htm" rel="nofollow">http://www.codeguru.com/csharp/.net/article.php/c19405/Tracing-in-NET-and-Implementing-Your-Own-Trace-Listeners.htm</a> and from the way I understand it, once added to the <code>Trace.Listeners</code> a listener should log all thace info in the current exe, but that's obvioustly not the case.</p>
<p>So how to achieve that?</p>
<p>Edit: I've managed to hack around this limitation by dissasembling the TextWriterTraceListener and implementing my own TraceListener with the dissasembled code, adding if staatements in Write and WriteLine methods that check some static fields of another class, and adding my type in the config.</p>

Getting Azure SQL Server data into BigQuery
|
<p>Thank you in advance for your patience. I am writing a lengthy question to attempt to provide as much relevant info as possible.</p>
<p>My data is stored in Azure SQL Server (not by my choice) and I want to work with the data in Google BigQuery. I would like to update the data in BigQuery from SQL Server periodically (say once an hour or once every few hours for example). </p>
<p>I have found many ways to pull data from SQL Server and many ways to load data into BigQuery. What I've landed on as the easiest solution for now is creating a load job in BigQuery that uses the SQL Server URI. The data in SQL Server has auto modified/created tags that will indicate data that has been updated or added since the last load job. </p>
<p>But, I needed an IP address for BigQuery that I could add to my SQL Server whitelist to allow access to the SQL Server data. In Google documentation, the only way I could find to get an IP address was to set up a ComputeEngine VM (which I have done - and I obtained an IP address for the VM). </p>
<p>My question now is: how do I set up (or is it even possible to set up) the ComputeEngine VM to run the BigQuery load job so that the ComputeEngine IP will be used to request SQL Server? Or, in the alternative, how do I find the IP that will be used by BigQuery to make the request to SQL Server?</p>
<p>If you have any ideas - or another setup that I have not considered, please spell it out for me step-by-step. I am rather new to the industry.</p>
<p>Thank you again for your time and consideration.</p>

Can I cancel the loading of a URL in the InAppBrowser Cordova plugin from my Ionic 2 app?
|
<p>In my Ionic app, I need to open the login page of a third-party service in a new browser window. When the login succeeds, the third-party login page will fire a redirect request with a parameter I need to capture. Once I have the parameter, I need to effectively cancel the URL load request.</p>
<p>I have a native iOS implementation of this that opens the third-party login page in a web view and then uses the web view's shouldStartLoadWithRequest:requestNaviationType: method to capture the request and parse the parameters. Based on the parsed result, it either loads the URL or cancels the request.</p>
<p>The Cordova InAppBrowser function will allow me to open a URL in a new window, and it allows me to listen to the loadstart event. But how can I prevent the redirect URL from loading?</p>

JLine 3 - Keep the prompt always at the bottom
|
<p>I want the prompt to display at the bottom of the page every time.</p>
<p>I have a GIF of that: <a href="http://i.stack.imgur.com/ekbAj.gif" rel="nofollow">The prompt not displaying properly</a></p>
<p>The code is that for read line:</p>
<pre><code>@Override

String cmd;
((ElytraServer) ElytraAPI.getServer()).getReader().getTerminal().writer().flush();
cmd = ((ElytraServer) ElytraAPI.getServer()).getReader().readLine("> ");
if (!cmd.isEmpty())
{
String[] aCMD = cmd.split(" ");
String[] arguments = Arrays.copyOfRange(aCMD, 1, aCMD.length);
ElytraAPI.getCommandRegistry().dispatch(ElytraAPI.getConsole(), aCMD[0], arguments);
}
}
}

<p>It's in a Thread.</p>
<p>And there is the another Thread:
With JLine 2, the code keep the prompt at the bottom (But it was buggued !)</p>

Is it possible to keep my Nix packages in sync across machines not running NixOS?
|
<p>I know with NixOS, you can simply copy over the <code>configuration.nix</code> file to sync your OS state including installed packages between machines.</p>
<p>Is it possible then, to do the same using Nix the package manager on a non-NixOS OS to sync only the installed packages?</p>

How to use getDirection() properly with PointerLockControls in Three.js
|
<p>I'm using <code>PointerLockControls</code> in <code>Three.js</code>.</p>
<p>On mouse click, I want to update a sphere position to the position the camera is facing, at the same <code>z-position</code> of a certain object. I've read about <code>getDirection()</code>, but can't seem to implement it the right way. Here's what I tried:</p>
<pre><code>var mouse3D = new THREE.Vector3();
mouse3D.normalize();
controls.getDirection( mouse3D );
sphere.position.x = mouse3D.x;
sphere.position.y = mouse3D.y;
sphere.position.z = object.position.z;
</code></pre>
<p>The <code>z-position</code> is fine, but x and y are so close to 0 that the sphere stays "on the ground" and doesn't go "left or right".</p>
<p>Any help is much appreciated!</p>

Portable Eclipse C\C++ Configuration for C++ compiler (without computer installtion (c drive, PATH etc)) on USB
|
<p>I am trying to program in C++ using Eclipse. However, this requires Eclipse to work on different computers with a MinGW compiler installation everytime. I know that it will work if I install it on a computer and add the location to the PATH variable, but I want to know how to put the compiler onto my USB as well as the Eclipse program and make it work the same way. </p>
<p>It should be installed in such a way that Eclipse can find the compiler on my USB (without the PATH stuff and C drive installation) and compile my program successfully without giving a "Binary not found" error because it could not build my source code. </p>
<p>I've solved this problem with Eclipse Java and am completely able to write and compile Java code. However, I don't know how to do it for a C\C++ Eclipse. Can someone help me with this problem?</p>
<p>Thanks in advance!</p>

Change file (editor) encoding in jgrasp to UTF-8
|
<p>So... I was testing jGrasp and when i openned my testing file I saw something like this:</p>
<p><a href="http://i.imgur.com/QpdEHJb.png?1" rel="nofollow">¿Khà ?</a></p>
<p>instead of this:</p>
<p><a href="http://i.stack.imgur.com/zzrbZ.png" rel="nofollow">¿Khà?</a></p>
<p>but when i compile it, first i got the weird characters (the encoding was wrong). So i changed the encoding on the WorkSpace>Charset (the default, I/O and cygwin) to UTF-8 and got the correct output (like in the second image)... but it still looks the same on jGrasp.</p>
<p>If I change it on jGrasp so it looks "good", on other text editors will look diferent (and also in the compiler).</p>
<h3>EDIT</h3>
<p>I have found a few other encodings that work, but they aren't UTF-8, and also i don 't want to be changing every moment the encoding.</p>

PHP FPM Docker ZF1: The session has already been started. The session id must be set first

PHPMailer being rejected with "Host impersonating" when script run from CLI (cron)
|
<p>I host a site through bluehost.com, which has an email function that I've built around PHPMailer. It has been running fine, but it looks like bluehost have changed some security settings in the last 24 hours. Having debugged through it, I'm at a loss how to resolve this.</p>
<p>It looks like bluehost have configured their end to now validate the host that is connecting to the SMTP server. If I trigger an email while browsing the site, the email still sends fine:</p>
<pre><code>SERVER -> CLIENT: 220-box304.bluehost.com ESMTP Exim 4.86_2 #1 Wed, 20 Jul 2016 10:16:19 -0600 220-We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail.

CLIENT -> SERVER: AUTH LOGIN
...
SERVER -> CLIENT: 235 Authentication succeeded
</code></pre>
<p>Some (most) emails aren't sent interactively though, and are queued in a database, which a php script periodically executes in the background via a cron job, to send those emails out. This used to work fine, but as of yesterday, the script now throws errors:</p>
<pre><code>SERVER -> CLIENT: 220-box304.bluehost.com ESMTP Exim 4.86_2 #1 Wed, 20 Jul 2016 10:30:08 -0600 220-We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail.
CLIENT -> SERVER: EHLO box304.bluehost.com

CLIENT -> SERVER: QUIT
SERVER -> CLIENT: 221 box304.bluehost.com closing connection
SMTP connect() failed.
</code></pre>
<p>I can see that the interactive log identifies the source site www.fydentry.com, but the php script executed via the cli (cron), just sees the box name, and decides that isn't a valid source.</p>
<p>Is there a parameter I can add to the command line, so that the script appears to be running from the site address? Or something I can do within the PHP script to emulate this? Or is this a config issue on the bluehost side, that I should be asking them to rectify? Or have I totally missed something here, and there's something else I should have done?</p>
<p>At the moment I've hacked around the issue by calling a basic wrapper script in the cron job, which in turn executes this:</p>
<pre><code>file_get_contents("http://www.fydentry.com/my-mailer-script.php");
</code></pre>
<p>Which seems to sufficiently fool everything that the script is running from the site. But that doesn't seem like a good long term solution.</p>

Push paragraphs down to not overlap with page header in MigraDoc 1.5b3
|
<p>The code below aims to add an image and date stamp to the page header and then populate the page with some text (for example one header and a couple of paragraphs).</p>
<p>The problem is that the text overlaps the page header, it starts at the same height as the date stamp paragraph in the page header. What am I doing wrong?</p>
<pre><code>Section section = document.AddSection();
section.PageSetup.StartingNumber = 1;
Image image = section.Headers.Primary.AddImage(GetImageFromDB("LogoPageHeader")); // creates base64 encoded image string
image.LockAspectRatio = true;
image.RelativeVertical = RelativeVertical.Line;
image.RelativeHorizontal = RelativeHorizontal.Margin;
image.Top = ShapePosition.Top;
image.Left = ShapePosition.Left;
image.WrapFormat.Style = WrapStyle.TopBottom; // to push date stamp to below the bottom of the image
HeaderFooter header = section.Headers.Primary;
Paragraph paragraph = header.AddParagraph(DateTime.Now.ToString("MM/dd/yyyy"));
paragraph.Format.Alignment = ParagraphAlignment.Right;
Paragraph paragraph = document.LastSection.AddParagraph("Question Summary:", "Heading3");
paragraph = document.LastSection.AddParagraph();
paragraph.Format.Alignment = ParagraphAlignment.Left;
paragraph.AddText("Question: " + q.Text.Trim());
paragraph = document.LastSection.AddParagraph();

paragraph.Format.SpaceAfter = "8pt";
