d8201 | train | To be able to use read in your case, you need something like this using a special file descriptor :
while read crontab_entry; do ...
read -u3 -p 'question' yn
...
done 3<&0 < crontab.out
because STDIN is already fed by the crontab output
A: I used a special file descriptor for the cat command instead and done some modifications to the sed command to work correctly.
function cron_check()
{
crontab -l
result=$?
if [[ $result -eq 0 ]]; then
crontab -l > crontab.out
exec 3< crontab.out
while read -u 3 cron_entry

d8202 | train | Quite simply
1.) Create app on Facebook, get the app_id that you will subsequently use to attach to your app.
2.) Define your applicationId in the AndroidManifest.xml like this:
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
under <application android:label="@string/app_name".... tag
where app_id is a string within your strings.xml.
Example (Facebook Sample application):
<application android:label="@string/app_name"
android:icon="@drawable/icon"
android:theme="@android:style/Theme.NoTitleBar"
>
<activity android:name=".HelloFacebookSampleActivity"
android:label="@string/app_name"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name="com.facebook.LoginActivity"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:label="@string/app_name" />
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
</application>
Note the value added under the <application> tag
and in strings.xml (MAKE SURE TO DO THIS)
<string name="app_id">xxxxxxxxxxxx</string>
3.) Set permissions in manifest
<uses-permission android:name="android.permission.INTERNET"/>
This is an android requirement, so the app can access the internet.
So with permissions the above manifest will look like
<uses-permission android:name="android.permission.INTERNET" />
<application android:label="@string/app_name"
android:icon="@drawable/icon"
android:theme="@android:style/Theme.NoTitleBar"
>
<activity android:name=".HelloFacebookSampleActivity"
android:label="@string/app_name"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name="com.facebook.LoginActivity"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:label="@string/app_name" />
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
</application>

d8204 | train | you can either use map.on('layeradd') and or try the layeradd
event on your layer1 object.
leaflet's documentation link: http://leafletjs.com/reference-1.0.3.html#layerevent
EDIT... add the following code to js-fiddle code.
layer1.on('add',(e)=>{
layer2.addTo(mymap);
});
layer1.addTo(mymap);
if that doesn't remove the addTo line from above and paste the following
setTimeout(()=>{
layer1.addTo(mymap);
},500);
EDIT 2 :
var controlObj = L.control.layers(basemaps,overlays,{collapsed:false}).addTo(mymap);
layer1.on("add",function(){
console.log(controlObj._form[2].click())

this code works... but its not how it should be dont... will have to figureout a better way to do this, but this will work temporarily. | unknown | |
d8205 | train | You have to define the fields before using it.
In your jrxml, you have three field defined students in the subDataSet, id and students. But you haven't defined name and using it in your jrxml and that's why you are getting this exception.
Try defining name, like
<field name="name" class="java.lang.String"/>
A: Try with a subreport. I launched your example in my local database without any problem.
This is my list of student objects:

List<Student> students = new ArrayList<Student>();
Connection con = ....; //Retrieve your connection the way you want
ResultSet rs = con.createStatement().executeQuery("select name, id from students order by id");
while (rs.next()){

d8206 | train | In this case, the underlying data source does not support editing since the properties of anonymous types are read only. Per the C# language spec:
The members of an anonymous type are a sequence of read-only properties inferred from the anonymous object initializer used to create an instance of the type.
Instead, you might want to define a display class with editable properties for the values you want to display and create instances of that class.
A: I had this problem with an unbound DGV. I fixed it by setting the ReadOnly property of each ROW. Both the DGV and the Columns were not ReadOnly, but the Rows were somehow being set R/O perhaps when I set them using a collection.
So:
foreach (var r in Lst)

However, with your operator<<, you will no longer be able to use expressions such as std::cout << true in namespace Foo, because this will trigger an ambiguity between your Foo::operator<<(std::ostream&, bool) and std::ostream's member function std::ostream::operator<<(bool): both accept an lvalue of type std::ostream as its left operand, and both accept a value of type bool as its right operand, neither is better than the other. | unknown | |

Mac chrome - Mime Type:audio/webm;codecs=opus
Mac Safari - Mime Type:audio/mp4

*
*Use something to render the page first. The simplest in C# would be to have a WebBrowser control, and listen for the DocumentCompleted event. Note that there is some nuance to this when it fires for multiple documents on one page
*Figure out what service the page is calling to get the extra data, and see if you can access that directly. It may well be the case that the Canadapost website is accessing an API that you can also call directly. | unknown | |

d8216 | train | Apparently, on my Macbook, I see /etc directory having symlinks with the /private/etc directory which is owned by the wheel group & root is part of that group. So, you would need to use sudo to copy to that directory.
With that said on a Linux machine, you can work around this by adding your group to a new file in the /etc/sudoers.d/<group-name> path.
<grp-name> ALL=(ALL) NOPASSWD:ALL
I've just tried this on my mac, I could copy files onto /private/etc directory without entering the sudo password prompt.
Unfortunately, this comes up with some risks as users of your group get privileged access without entering any password prompt. You might accidentally delete important system files etc.,
A more niche approach could be to allow selectively like <group> ALL = (ALL) NOPASSWD: /usr/local/bin/copy-script. This way, they can't run all scripts/commands with sudo privileges. | unknown | |
d8217 | train | Python classes have three attributes that help here:
*
*class.__subclasses__(); a method that returns all subclasses of the class.
*class.__bases__, a tuple of the direct parent classes of the current class.
*class.__mro__, a tuple with all classes in the current class hierarchy. Find the current class object in that tuple and everything following is a parent class, directly or indirectly.
Using these that gives:
class SuperClass(object):
def print(self):
print('my sub classes are:', ', '.join([
cls.__name__ for cls in type(self).__subclasses__()]))
class Sub1(SuperClass):
def print(self):
print('My direct parents are:', ', '.join([

d8220 | train | Look at GROUP_CONCAT but it may be easier to retrieve the data in multiple rows (you can sort to put repeats adjacent to each other) and process in code.
A: This is similar to Aggregating results from SPARQL query, but the problem is actually a bit more complex, because there are multiple variables that have more than one result. ?name, ?office, and ?birthPlace have the same issue.
You can work around this using group_concat, but you'll need to use distinct as well, to keep from getting, e.g., the same ?year repeated multiple times in your concatenated string. group by reduces the number of rows that you have in a solution, but in each of those rows, you have a set of values for the variables that you didn't group by. E.g., since ?year isn't in the group by, you have a set of values for ?year, and you have to do something with them. You could, e.g., select (sample(?year) as ?aYear) to grab just one from the set, or you could do as we've done here, and select (group_concat(distinct ?year;separator=", ") as ?years) to concatenate the distinct values into a string.
You'll want a query like the following, which produces one row:
SELECT ?x
(group_concat(distinct ?name;separator="; ") as ?names)
?abs
?birthDate
(group_concat(distinct ?birthplace;separator=", ") as ?birthPlaces)
(group_concat(distinct ?year;separator=", ") as ?years)
?party

d8225 | train | Authy developer evangelist here.
With Authy, the secret key is not exposed to you, the developer, for security reasons. It is only shared with the user directly via the application, without them having to do anything, as you described. Authy, in fact, manages the keys between the app and the user more than just on the first occasion, as keys can be rotated regularly without your or the user's intervention.
If a user is finding that they have signed up to your site but your application isn't appearing in their Authy app then a couple of things might have happened.
*
*Their phone may not be on a network at the time they signed up, leading to them not being able to receive the secret key from Authy
This should resolve itself over time as the user will eventually get their phone back on a network. You might consider suggesting they install Authy Desktop to use their desktop computer to authorise.
Alternatively, you could ensure they get a token and finish registering with your site by giving them the option to receive the token over SMS and forcing the token to be sent over SMS, using the force parameter when requesting a token.
*
*They may have signed up to your 2FA using a different phone number than the one they initially signed up to Authy with.
For this, again, you may want to give them the option to receive a token by SMS. Or get the user to check their Authy account settings in the application and perhaps re-enter their phone number.
Overall, you won't get access to the secret or a QR code as that is not how Authy manages the secrets. Instead, either give the option to receive an SMS or get them to install an application on a device that has a connection.

d8228 | train | No temporary copies are created during the construction of matrixU and matrixV. Eigen::JacobiSVD inherits from Eigen::SVDBase, which defines the member functions matrixU() and matrixV() which just return a reference to the protected member variables of Eigen::SVDBase that hold the actual matrices.
However, you are still copying data, but explicitly: you copy the two matrices from the local variable svd into member variables of Foo. If you do not need to modify the U and V matrices in-place, you could store the whole svd in Foo, like so:
class Foo {
public:
JacobiSVD svd;
Foo(const Ref<const MatrixXcd>& mat);
};
Foo::Foo(const Ref<const MatrixXcd>& mat):
svd(mat, Eigen::ComputeFullU | Eigen::ComputeFullV) {
// proceed to do other things

d8230 | train | First, I would suggest creating a function for the purpose of opening each dat-file. Please replace the read.table function by the function you use for opening the dat-files. In this case, the function contains both coordinates and the months to which respect it filters the dataframe as arguments. Arguments could however be extended by year and days for instance. To keep it simple I only included months.
open_dat <- function(X, Y, left, right) {
dat <- read.table(paste("hourly", X, Y, "2005.dat", sep = "_"),
header=TRUE) %>% as.tibble()
dat$X <- X
dat$Y <- Y
dat %>% filter(between(Month, left, right))
}
Then, we can apply the function to the dataframe that contains X and Y for the days that are between May and July (numbers 5 and 7):
full_df <- map2_dfr(df$X, df$Y, open_dat, left = 5, right =7) | unknown | |
d8231 | train | The only way to do that would be to ask the Widget developer to do something like this:
$cat_args_depth = 1;
$cat_args_depth = apply_filters('woocommerce_cat_args_depth', $cat_args_depth );
$cat_args['depth'] = $cat_args_depth;
and then you could just use
add_filter( 'woocommerce_cat_args_depth', function( $cat_args_depth ) {
$cat_args_depth = 2; // your value
return $cat_args_depth ;
}); | unknown | |
d8232 | train | First of all you said Can't drop table. But in post you mentioned ALTER TABLE table ENGINE=INFINIDB.
But DROP != ALTER it is two different things.
So you can do following:
*
*CREATE new table with same structure but engine you need.
*copy(UPDATE) data from old table to the one you just created.
*DROP old table.
*RENAMErename new one to old name
A: It turned out that another process (a website) was using this database and had a couple of queries that got 'stuck' in the SQL server and caused the table to hang due to the database using the wrong engine, which I'm assuming was InnoDB since I didn't specify an engine when I initially used the "CREATE TABLE table1 AS SELECT * FROM table2" command. We finally managed to wipe the database and start over. Thanks for your help. | unknown | |

d8235 | train | If you have an array of image urls, you can use setInterval to periodically update your header/footer images. Something like this:
var imgUrls = [
'assets/img/bg1.jpg',
'assets/img/bg2.jpg',
'assets/img/bg3.jpg',
'assets/img/bg4.jpg',
// ... etc.
];
var currentImageIndex = 0;
// Create a callback that will be invoked every 10 seconds
setInterval(function() {
var imgUrl = imgUrls[currentImageIndex++];
$('header').css('background', 'url(" + imgUrl + ") center center').css('background-size', 'cover');
$('footer').css('background', 'url(" + imgUrl + ") center center').css('background-size', 'cover');
// Make sure the currentImageIndex doesn't get too big
if (currentImageIndex >= imgUrls.length) {
currentImageIndex = 0;
}
}, 10000);
A: Another solution :
$(function() {
let pictures = ["bg3.jpg", "bg2.jpg", "bg1.jpg"];
$.each(pictures, function(i,e) {
setTimeout(function() {
changeHeaderImg(e);
}, i*10000);
});
}
function changeHeaderImg(pictureName: string) {
$('header').css('background', 'url(assets/img/'+pictureName+') center center').css('background-size', 'cover');
$('footer').css('background', 'url(assets/img/'+pictureName+') center center').css('background-size', 'cover');
}
A: This will work for any number of images as long as you keep following your 'assets/img/bg' + num + '.jpg' format. Just set the number of headers you have at the top and you're good to go.
$(function() {
var numHeaders = 4;
var header = 0;
setInterval(function() {
header++;
if (header > numHeaders) {
header = 1;
}
$('header').css('background', 'url(assets/img/bg' + header + '.jpg) center center').css('background-size', 'cover');
$('footer').css('background', 'url(assets/img/bg' + header + '.jpg) center center').css('background-size', 'cover');
}, 10000);

A: You'd have much more than 1296 possibilities with 2 characters if you wanted to use all the unicode characters that are allowed in an XML name!
Unfortunately, XSLT processors are free to decide how that create IDs for the generate-id() function (meaning that depending on the processor you are using you can get more or less then 8 characters).
That being said, if that's really important to you, you should be able to write your own generate-id() based on the number of preceding siblings and ancestor node nodes (count(ancestor::node()|preceding::node()))... You could convert this number into a two character id using lookup tables or any other mechanism and that would probably not be very efficient but that should work... | unknown | |

d8248 | train | Right out of head, a dumb method: a binary search in C:\Windows\System32 for GetProcessDpiAwareness, then studying each occurrence with Dependency Walker for exports.
This produces the result: GetProcessDpiAwareness is exported by SHCore.dll.
One may also search the Windows SDK headers and libs, but in my case I haven't found GetProcessDpiAwareness, to my surprise.
Another idea, run the following from the command line prompt:
for %f in (%windir%\system32\*.dll) do dumpbin.exe /exports %f >>%temp%\__exports
Then search %temp%\__exports for the API.
A: I know it's been asked a while back. (Every time I Google it, this question comes up. So let me share my method.)
If anyone wants to search for functions in DLLs, there's this tool that will do it for you. In case of the GetProcessDpiAwareness on my Windows 10 (64-bit) it is exported from shcore.dll like someone had already mentioned above. Here's the screenshot:
Although I need to preface it by saying that it would be always prudent to refer to the function's documentation on MSDN instead. Currently you can find it at the bottom of each page:
If you play around with the search that I showed above, you will notice that many of the system functions are exported from multiple DLLs (some of which are undocumented.) So if you just blindly go with whatever you find in a search app, you may run a risk of breaking your program in the future if Microsoft changes one of those undocumented functions. So use it only for your own research or curiosity.
A: Usually functions that work with the same resources are in the same dll's. Look at another dpi function like GetDpiForMonitor and you will see it is in Shcore.dll
Edit: After you find the dll this way you can double check using dependency walker to see what functions are exported from that dll. | unknown | |

d8252 | train | Had same issue, I don't want a pipeline launch on pipeline creation (which is the default beahviour).
Best solution I fount is :
*
*Create an EventBridge rule which catch the pipelineExecution on
pipeline creation
*Stop the pipeline execution from the lambda triggered
Rule looks like this :
{
"source": ["aws.codepipeline"],
"detail-type": ["CodePipeline Pipeline Execution State Change"],
"detail": {
"state": ["STARTED"],
"execution-trigger": {
"trigger-type": ["CreatePipeline"]
}
}
}
It works fine
A: Sadly, there seem to be no way of this this. Docs clearly states that a newly created pipeline immediately starts running:
Now that you've created your pipeline, you can view it in the console. The pipeline starts to run after you create it.
The initial run will always happen. Subsequent runs depend on your source action. For example, if you use CodeCommit as your source, you can disable CloudWatch Event that triggers the pipeline.
Thus if you want to use CodePipeline in your project, you have to design it so that it does not causes any issues due to immediate start.
A: You can disable the Event rule from automatically starting your pipeline.
Go to Amazon EventBridge -> Rules and disable the rule that notifies the CodePipeline.
A: Further to Marcin's comment, it would seem there are 2 approaches you can take which would limit the run of the pipeline.
*
*Create a disabled StageTransition or Manual Approval stage directly after the Source stage. This would prevent the pipeline executing any other action aside from getting the source which would have no impact or capability to re-write anything.
*Alternatively if your source stage is from a repository, you can opt to handle the pipeline triggers yourself by disabling the PollForSourceChanges parameter in your cloudformation template.
Pipeline:
Type: AWS::CodePipeline::Pipeline
Properties:
Name: *NAME*
RoleArn: *IAMROLE*
Stages:
- Name: Source
Actions:
- Name: CodeCommitSourceAction
RunOrder: 1
ActionTypeId:
Category: Source
Provider: CodeCommit
Owner: AWS
Version: '1'
OutputArtifacts:
- Name: Source
Configuration:
RepositoryName: *REPOSITORYNAME*
BranchName: *BRANCH*
PollForSourceChanges: "false" #prevents codepipeline polling repository for changes.
A: So the correct answer is...
*
*Commit your code before you deploy for the first time
*Deploy only the pipeline
*Let Code Pipeline do its thing
99% of cases it will finish sooner than your machine. | unknown | |
d8253 | train | Assuming that this uses Meteor-Blaze templates you need to include the conditionals for DOM element attributes inside quotes/double quotes:
<a-gltf-model id='playerone' class="{{#if myplayer playerone}}entitymove{{/if}}" src="#myMixBun"> </a-gltf-model>
Readings:
http://blazejs.org/guide/spacebars.html
A: SOLVED
This is my original, which doesn’t work.
In main.js:
player = "player not active";
Template.hello.helpers(
counter() {......
// if player one
player = "playerone";
// if player two
player = "playertwo";
return { myplayer: player };
}
In main.html:
// This statement works
{{counter.myplayer}}....
<a-gltf-model id='playerone' class="{{#if counter.myplayer playerone}}entitymove{{/if}}" src="#myMixBun"> </a-gltf-model>
<a-gltf-model id='playertwo' class="{{#if counter.myplayer playertwo}}entitymove{{/if}}" src="#myMixBun"> </a-gltf-model>
I think there are 2 problems with this:
1) spacebars doesn’t seem to like the if statement with a comparison?:
{{#if counter.myplayer playertwo}}
It only allows true or false if statements?, such as:
{{#if counter.player1}}
2) My aframe custom component isn’t actually a class, so I can’t put the meteor #if statement inside the entity.
I changed the code to the following and it now works:
Changed main.js to:
playerone ="";
playertwo ="";
// if player one
playerone = "true";
playertwo = "";
// if player two
playerone = "";
playertwo = "true";
return { player1: playerone, player2: playertwo};
}
Changed main.html to:
// These statements work
{{#if counter.player1}}player1 is true{{/if}}
{{#if counter.player2}}player2 is true{{/if}}....
{{#if counter.player1}}
<a-gltf-model id='playerone' entitymove src="#myMixBun" ></a-gltf-model>
<a-gltf-model id='playertwo' src="#myMixBun" ></a-gltf-model>

A: You should be able to override the settings inside machine.config by adding the same node into your application's web.config like so. Microsoft has some information about ASP.NET Configuration File Hierarchy and Inheritance.
NOTE: Erik Philips is right and the max size of maxRequestLength is 2,147,483,647 (Int32.MaxValue). This answer is to illustrate how to override a setting defined in machine.config (or any .config) from within your application's web.config/
<configuration>
...
<system.web>
<httpRuntime maxRequestLength="2147483647"/>
...
...
</system.web>
...
</configuration>
In doing this though, you might also want to increase your timeout or it might, well, time out. | unknown | |
d8260 | train | Even if you can have more then a single http block you should not do it. But having an http block in another http block IS NOT ALLOWED and will raise an error on startup. Just tested this on my instance. So you should check the output of nginx -T and check the configuration.
The NGINX configuration works in an hierarchical order. Means a directive you set in the http context can be overwritten in the server or location context if supported. | unknown | |
d8261 | train | Based on the code you've provided, it looks like listObjects is a function that accepts an object and a callback, and at some point calls that callback, so probably the simplest way to mock it would be like this:
listObjects: (_, c) => c()
The function you're testing only seems to care whether listObjects is passing an error to the callback or not, so this should seemingly be sufficient.
Side note: you have return resolve in two places in your isS3Healthy function, but using return here almost certainly serves no purpose. To resolve a promise, just call resolve(...) without returning it. | unknown | |
d8262 | train | I can suggest you to do the next (I didn't test this so let me know if it does not work).
This plugin allows you to specify custom regexes for validation. All regexes are placed in the so called translation file (jquery.validationEngine-en.js for English). There you can see $.validationEngineLanguage.allRules object. Add to it your custom rule where you need to set your own regex to forbid (gmail, hotmail etc):
"custom_email": {
"regex": /^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@(?!gmail\.com|hotmail\.com)[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/,
"alertText": "* Invalid email address"
},
You can see that I added almost default regexp, which was specified in the "email" rule, but included to it the negative lookahead (?!gmail\.com|hotmail.com) (you can add another domains with |newemail\.com approach).
Then you need to set this custom rule for your input:
<input value="" class="validate[custom[custom_email]]" type="text" name="email" id="email" /> | unknown | |
d8263 | train | As JDro04 pointed out, you can use Thread.Sleep to do delay. But your app will hang if you do it from main thread. So you can do delay in separate thread and invoke MessageBox.Show in the main one, here's the snippet:
private void Button1_Click(object sender, RoutedEventArgs e)
{
Task.Factory
.StartNew(() => Thread.Sleep(4000))
.ContinueWith(
continuationAction: _ => { MessageBox.Show("My message!"); /* put rest of your code here */ },
cancellationToken: CancellationToken.None,
continuationOptions: TaskContinuationOptions.None,
scheduler: TaskScheduler.FromCurrentSynchronizationContext());
} | unknown | |
d8264 | train | Absolutely not, in so many ways that it would be hard to count them all.
First and foremost, the memory layout of arguments is simply not specified by the C language. Full stop. It is not specified. Thus the answer is "no" immediately.
va_list exists because there was a need to be able to navigate a list of varadic arguments because it wasn't specified other than that. va_list is intentionally very limited, so that it works on platforms where the shape of the stack does not match your intuition.
Other reasons it can't always be 4:
*
*What if you pass an object of length 8?
*What if the compiler optimizes a reference to actually point at the object in another frame?
*What if the compiler adds padding, perhaps to align a 64-bit number on a 64-bit boundary?
*What if the stack is built in the opposite direction (such that the difference would be -4 instead of +4)
The list goes on and on. C does not specify the relative addresses between arguments.
A: As the other answers correctly say:
No.
Furthermore, even trying to determine whether the addresses differ by 4 bytes, depending on how you do it, probably has undefined behavior, which means the C standard says nothing about what your program does.
void func(long a, long b)
{
printf("%d\n", (int)&b - (int)&a);
}
&a and &b are expression of type long*. Converting a pointer to int is legal, but the result is implementation-defined, and "If the result cannot be represented in the integer type, the behavior is undefined. The result need not be in the range of values of any integer type."
It's very likely that pointers are 64 bits and int is 32 bits, so the conversions could lose information.
Most likely the conversions will give you values of type int, but they don't necessarily have any meaning, nor does their difference.
Now you can subtract pointer values directly, with a result of the signed integer type ptrdiff_t (which, unlike int, is probably big enough to hold the result).
printf("%td\n", &b - &a);
But "When two pointers are subtracted, both shall point to elements of the same array object, or one past the last element of the array object; the result is the difference of the subscripts of the two array elements." Pointers to distinct object cannot be meaningfully compared or subtracted.
Having said all that, it's likely that the implementation you're using has a memory model that's reasonably straightforward, and that pointer values are in effect represented as indices into a monolithic memory space. Comparing &b vs. &a is not permitted by the C language, but examining the values can provide some insight about what's going on behind the curtain -- which can be especially useful if you're tracking down a bug.
Here's something you can do portably to examine the addresses:
printf("&a = %p\n", (void*)&a);
printf("&b = %p\n", (void*)&b);
The result you're seeing for the subtraction (4) suggests that type long is probably 4 bytes (32 bits) on your system. I'd guess you're on Windows. It also suggests something about the way function parameters are allocated -- something that you as a programmer should almost never have to care about, but is worth understanding anyway.
A:
[...] I was just curious if the addresses of a function's parameters are always in a difference of 4 bytes from one another."
The greatest error in your reasoning is to think that the parameters exist in memory at all.
I am running this program on x86-64:
#include <stdio.h>
#include <stdint.h>
void func(long a, long b)
{
printf("%d\n", (int)((intptr_t)&b - (intptr_t)&a));
}
int main(void)
{
func(1, 2);
}
and compile it with gcc -O3 it prints 8, proving that your guess is absolutely wrong. Except... when I compile it without optimization it prints out -8.
X86-64 SYSV calling convention says that the arguments are passed in registers instead of being passed in memory. a and b do not have an address until you take their address with & - then the compiler is caught with its pants down from cheating the as-if rule and it quickly pulls up its pants and stuffs them into some memory location so that they can have their address taken, but it is in no way consistent in where they're stored. | unknown | |

window.innerHeight
You can know the height of the browser window and style your elements accordingly.
I am assuming that by fold you mean what you see without scrolling.
If you need a more backwards compatible (<I.E9) height and you can use jquery:
$( window ).height();
A: You might try using the css unit of measurement vh. Say you have a div that you only want to take up half the screen (viewport) you would do something like this:
div{
height: 50vh;
}
vh stands for "Viewport Height" and is used like a percentage. So to have the div always take up 100% of the view-able area (viewport), regardless of the screen size or resolution you would do this: div { height: 100vh; }
A: I would use document.documentElement.clientHeight and document.documentElement.clientWidth which are essentially the width and height of the html element:
$('div').css({'height':document.documentElement.clientHeight+'px',
'width':document.documentElement.clientWidth+'px'});

You would have to re-execute this code every time the window is resized to keep the bottom of the box flush with the page fold. | unknown | |
d8268 | train | To add to andyhasit's answer, using a service account is the correct and easiest way to do this.
The problem with using the JSON key file is it becomes hard to deploy code anywhere else, because you don't want the file in version control. An easier solution is to use an environment variable like so:
https://benjames.io/2020/09/13/authorise-your-python-google-drive-api-the-easy-way/
A: You can do this, but need to use a Service Account, which is (or rather can be used as) an account for an application, and doesn't require a browser to open.
The documentation is here: https://developers.google.com/api-client-library/python/auth/service-accounts
And an example (without PyDrive, which is just a wrapper around all this, but makes service account a bit trickier):
from apiclient.discovery import build
from oauth2client.service_account import ServiceAccountCredentials
from httplib2 import Http
scopes = ['https://www.googleapis.com/auth/drive.readonly']
credentials = ServiceAccountCredentials.from_json_keyfile_name('YourDownloadedFile-5ahjaosi2df2d.json', scopes)
http_auth = credentials.authorize(Http())
drive = build('drive', 'v3', http=http_auth)

A: Checkout the Using OAuth 2.0 for Web Server Applications. It seems that's what you're looking for.
Any application that uses OAuth 2.0 to access Google APIs must have
authorization credentials that identify the application to Google's
OAuth 2.0 server. The following steps explain how to create
credentials for your project. Your applications can then use the
credentials to access APIs that you have enabled for that project.
Open the Credentials page in the API Console. Click Create credentials
OAuth client ID. Complete the form. Set the application type to Web application. Applications that use languages and frameworks like PHP,
Java, Python, Ruby, and .NET must specify authorized redirect URIs.
The redirect URIs are the endpoints to which the OAuth 2.0 server can
send responses. For testing, you can specify URIs that refer to the
local machine, such as http://localhost:8080.
We recommend that you design your app's auth endpoints so that your
application does not expose authorization codes to other resources on
the page.

d8269 | train | This bit:
vars.put("old_date_submitted", "submittedDate"); // submittedDate, succeeddedDate and runningDates are regular expr. reference names
vars.put("old_date_succeeded", "succeededDate");
vars.put("old_date_running", "runningDate");
seems odd to me. Given:
submittedDate, succeeddedDate and runningDates are regular expr. reference names
My expectation is that you should be using JMeter Variables instead of hardcoded strings there, so you should change your code to look like:
vars.put("old_date_submitted", vars.get("submittedDate")); // submittedDate, succeeddedDate and runningDates are regular expr. reference names
vars.put("old_date_succeeded", vars.get("succeededDate"));
vars.put("old_date_running", vars.get("runningDate"));
So most likely your code is failing at DatatypeConverter.parseDateTime.
Next time you face any problem with your Beanshell scripts consider the following troubleshooting techniques:
*
*Check jmeter.log file - in case of Beanshell script failure the error will be printed there
*Add debug(); directive to the very beginning of your Beanshell script - it will trigger debugging output to stdout
*Put your Beanshell code in try/catch block like:
try {
//your code here
}
catch (Throwable ex) {
log.error("Something went wrong", ex);
throw ex;
}
This way you get more "human-friendly" stacktrace printed to jmeter.log file.

d8270 | train | This can be done using purrr::pmap, which passes a list of arguments to a function that accepts "dots". Since most functions like mean, sd, etc. work with vectors, you need to pair the call with a domain lifter:
df_1 %>% select(-y) %>% mutate( var = pmap(., lift_vd(mean)) )
# x.1 x.2 x.3 x.4 var
# 1 70.12072 62.99024 54.00672 86.81358 68.48282
# 2 49.40462 47.00752 21.99248 78.87789 49.32063
df_1 %>% select(-y) %>% mutate( var = pmap(., lift_vd(sd)) )
# x.1 x.2 x.3 x.4 var
# 1 70.12072 62.99024 54.00672 86.81358 13.88555
# 2 49.40462 47.00752 21.99248 78.87789 23.27958
The function sum accepts dots directly, so you don't need to lift its domain:
df_1 %>% select(-y) %>% mutate( var = pmap(., sum) )
# x.1 x.2 x.3 x.4 var
# 1 70.12072 62.99024 54.00672 86.81358 273.9313
# 2 49.40462 47.00752 21.99248 78.87789 197.2825
Everything conforms to the standard dplyr data processing, so all three can be combined as separate arguments to mutate:
df_1 %>% select(-y) %>%
mutate( v1 = pmap(., lift_vd(mean)),
v2 = pmap(., lift_vd(sd)),
v3 = pmap(., sum) )
# x.1 x.2 x.3 x.4 v1 v2 v3
# 1 70.12072 62.99024 54.00672 86.81358 68.48282 13.88555 273.9313

A: I think this is tricky because the scoped variants of mutate (mutate_at, mutate_all, mutate_if) are generally aimed at executing a function on a specific column, instead of creating an operation that uses all columns.
The simplest solution I can come up with basically amounts to creating a vector (cols) that is then used to execute the summary operation:
library(dplyr)
library(purrr)
df_1 <- data.frame(
x = replicate(4, runif(30, 20, 100)),
y = sample(1:3, 30, replace = TRUE)

# create vector of columns to operate on
cols <- names(df_1)
cols <- cols[map_lgl(df_1, is.numeric)]
cols <- cols[! cols %in% c("y")]

NOTE: if you are unfamiliar with purrr, you can also use something like lapply, etc.
You can read more about these types of more tricky dplyr operations (!!, !!!, etc.) here:
https://dplyr.tidyverse.org/articles/programming.html
A: This is a tricky problem since dplyr operates column-wise for many operations. I originally used apply from base R to apply over rows, but apply is problematic when handling character and numeric types.
Instead we can use (the aging) plyr and adply to do this simply, since plyr lets us treat a one-row data frame as a vector:
df_1 %>% select(-y) %>% adply(1, function(df) c(v1 = sd(df[1, ])))
Note some functions like var won't work on a one-row data frame so we need to convert to vector using as.numeric. | unknown | |
d8271 | train | Short answer: No, it's not equivalent.
When you use synchronized around that return ao;, the ArrayList is only synchronized during the return instruction. This means that 2 threads cannot get the object at the exact same time, but once they have got it, they can modify it at the same time.
If 2 threads execute this code, the add() is not thread safe:
ArrayList<?> list = getAo(); // cannot be executed concurrently
list.add(something); // CAN be executed concurrently
Side note: don't use Vectors, take a look at this post to know why.
A: They aren't equivalent. What you're looking for is Collections.synchronizedList which can "wrap around" any list, including ArrayList.
A: to do the equivalent of Vector you should protect any access to any element in the collection, the method getAo simply sychronize the access to the array list.
If two threads call getAo and after each thread call "add" method over this arraylist then you could have a multi thread problem (because "add" is not synch").
I recommend you to check the atomic classes like CopyOnWriteArrayList:

d8272 | train | You could replace }{ with a },{, parse it and take Object.assign for getting an object with indices as properties from an array.

.as-console-wrapper { max-height: 100% !important; top: auto; }
A: If they're in an array, it's fairly simple - just use reduce:
const data = [{"device_type":"iphone","filter_data":{"title":{"value":"Lorem Ipsum..","data":{}},"message":{"value":"Lorem Ipsum is simply dummy text of the printing...","data":{}},"dismiss_button":{"value":"Ok","data":{}},"action_url":{"value":"","data":{"type":"custom"}}}},{"device_type":"iphone","filter_data":{"message":{"value":"Push Message goes here.","data":{}}}}];
const res = data.reduce((a, c, i) => (a[i] = c, a), {});
console.log(res);
.as-console-wrapper { max-height: 100% !important; top: auto; }
A: You can use Array.protoype.match to separate each object then Array.protoype.reduce to get expected oject.
let a = '{"device_type":"iphone","filter_data":{"title":{"value":"Lorem Ipsum..","data":{}},"message":{"value":"Lorem Ipsum is simply dummy text of the printing...","data":{}},"dismiss_button":{"value":"Ok","data":{}},"action_url":{"value":"","data":{"type":"custom"}}}}{"device_type":"iphone","filter_data":{"message":{"value":"Push Message goes here.","data":{}}}}';
let objects = a.match(/({"device_type".*?}}}})/g).map(e => JSON.parse(e));
console.log('Array of objects',objects)
const out = {...[objects]};
console.log('\ndesired output',out)
Also, it seems to be useless to convert the array into an object when the keys are just the indexes. | unknown | |

d8275 | train | From the documentation
NSDate objects encapsulate a single point in time, independent of any particular calendrical system or time zone. Date objects are immutable, representing an invariant time interval relative to an absolute reference date (00:00:00 UTC on 1 January 2001).
Since sqlite does not support NSDate directly, the date is persisted as the underlying value. 530963469.705571 represents the number of seconds between 00:00:00 UTC on 1 January 2001 and the time when you created the NSDate
You can use the NSDate initialiser init(timeIntervalSinceReferenceDate:) to create an NSDate from the time interval value. | unknown | |
d8276 | train | Solved it, apparently this code needed to be removed:
OutputStream outputStream = conn.getOutputStream();
outputStream.close();
I guess it was because I gave a GET URL and put that outputStream in my code and that caused the issues.
I still however don't understand why I got the "405: method GET not allowed" whereas I think I should have gotten the opposite: "POST" not allowed...
Anyway that is my solution, thanks a lot for your help guys !
A: HTTP 405 is caused by bad method call (Method not Allowed). That means you called GET method on POST request or vice-versa. You should add handling for you GET method on your Web-Service to get it working.
A: For anyone still reaching here from a search engine, my solution was similar -
I removed the line "conn.setDoOutput(true);" (or set it to false) | unknown | |
d8277 | train | If i am not wrong you just want to read a text from remote file, so here it is.
NSString * result = NULL;
NSError *err = nil;
NSURL * urlToRequest = [NSURL URLWithString:@"YOUR_REMOTE_FILE_URL"];//like "http://www.example.org/abc.txt"
if(urlToRequest)
{
result = [NSString stringWithContentsOfURL: urlToRequest
encoding:NSUTF8StringEncoding error:&err];
}
if(!err){
NSLog(@"Result::%@",result);
}
A: To load the remote txt file, you should take a look at NSURLConnection or AFNetworking (there are other possibilities, these two are probably the most common).
You will then get the content of the file. Depending on what you intend to do with it, you may have to parse it, either with something as simple as -[NSString componentsSeparatedByString:] or with something a bit more powerful like NSScanner.
A: There are three steps involved in loading a file
*
*create the object that specifies the location of the file
*call the appropriate NSString class method to load the file into a
string
*handle the error if the file is not found
In step 1, you need to either create an NSString with the full path to the file in the file system, or you need to create an NSURL with the network location of the file. In the example below, the code creates an NSURL since your file is on the network.
In step 2, use the stringWithContentsOfFile method to load a file from the file system, or the stringWithContentsOfURL method to load a file from the network. In either case, you can specify the file encoding, or ask iOS to auto-detect the file encoding. The code below auto detects while loading from the network.
In step 3, the code below dumps the file to the debug console if successful or dumps the error object to the console on failure.
Missing from this code is multithreading. The code will block until the file is loaded. Running the code on a background thread, and properly notifying the main thread when the download is complete, is left as an exercise for the reader.
NSURL *url = [NSURL URLWithString:@"www.example.com/somefile.txt"];
NSStringEncoding encoding;
NSError *error;
NSString *str = [NSString stringWithContentsOfURL:url usedEncoding:&encoding error:&error];
if ( str )
NSLog( @"%@", str );
else

d8279 | train | There are a couple of guidelines that I follow when writing complex data structures in C++:
*
*Avoid raw pointers; use smart pointers.
*Try to figure out early on if your data structure is cyclic or acyclic. If there are cycles in your data structure you won't be able to used share_ptr everywhere without creating a leak. At some point in your cyclic structure you want to break the cycle with a weak_ptr, so that objects can be released.
*If my object holds onto other objects, and I want it to be a container, I implement the appropriate iterators when I need them, and not one second before. I usually need iterator support when I want to use one of the STL algorithms on my container. I could, of course, implement iterators that don't match the STL (in terms of naming or semantics) for my own use, but then I've added yet another way to do things in my code. I try to avoid that.
*If my class is intended to hold different types, then I use templates to express that. There are ways to do this in C (using memcpy, etc), but while the code you'll end up with will be more understandable to C coders, you will lose most of the benefits of C++ (type safety, assignment operators, etc). | unknown | |
d8280 | train | If you can identify your current page by class or id (ex: body > div#contacts) for contacts.html and this class/id is unique then you have to match it with you navigation, other way is to match window.location.href value (parsed if you want) against your navigation.
changeActiveLink is defined in JS (ex:init.js) file which you include to each page
function changeActiveLink() {
var currentLocation = window.location.href;
currentLocation = currentLocation.replace('//', '/').split('/');
var page = currentLocation[currentLocation.length - 1];
if (page == "") { page = 'index.html'; }
$('#leftNav1 a[href*="'+ page +'"]').addClass('active');
}
This line is called from each file when "init.js" is included.
$('#leftNav1').load('navigation.html', changeActiveLink);
A: Or you can use any HTML or even HTML5 tag to specify li item.
<li class="some">
or
<li title="some">
or
<li attr-specify="some-specific-in-url">
and jQuery with window.location object
$('li[title="' + window.location.path + '"]').addClass("active");
A: You could set up some jquery script to get the url and then find the href of the li that matches that. This will allow you to addClass() to that li of active.
This of course will only work if your href matches the url | unknown | |

d8282 | train | Banshee does not expose rating functions via DBus.
You can quickly view all functions that it exposes, using applications like d-feet[1]. Make sure that an instance of the application you are interested in (like Banshee in this case) is running.
There is a bug report already requesting to add rating functionality[2] to DBus interface. You might want to subscribe to it.
*
*https://fedorahosted.org/d-feet/
*https://bugzilla.gnome.org/show_bug.cgi?id=579754
A: Banshee does support rating via commandline since last year.
banshee --set-rating={1;2;3;4;5}
See the bug report for more options:
Add item rating to DBus interface
A: Sadly the developer have not implemented a GET method, so there is no common way to execute "rate current track 1 star up/down"-command, much less than a specific track.
Does anyone has written a script which provide this feature?
Yet, I haven't found any solution to modify the D-Bus Property via command line.
Finally here is my Workaround for rate the current played Track.
#!/bin/bash
#read current TrackRating
R=$(qdbus org.mpris.MediaPlayer2.banshee /org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Get org.mpris.MediaPlayer2.Player Metadata | grep 'userRating' | tr -d '/xesam:userRating: ')
case $R in
'' ) R=0 ;;
'0.2' ) R=1 ;;
'0.4' ) R=2 ;;
'0.6' ) R=3 ;;
'0.8' ) R=4 ;;
'1' ) R=5 ;;
esac
case $1 in
'inc' ) [ $R -lt 5 ]
banshee --set-rating=$(($R+1)) ;;
'dec' ) [ $R -gt 0 ]
banshee --set-rating=$(($R-1)) ;;
'res' ) banshee --set-rating=3 ;;
'min' ) banshee --set-rating=0 ;;
'max' ) banshee --set-rating=5 ;;
esac
Options:
*
*inc -> increase rating by one if possible
*dec -> decrease rating by one if possible
*res -> reset rating to three stars
*min -> set rating to zero stars
*max -> set rating to five stars
As far Banshee will not provide manipulating data of a specific Track this is my best bet. | unknown | |
d8283 | train | Assuming the select statement is part of a login form, then most likely it's generated something like this:
$user = $_POST['username'];
$pwd = $_POST['password'];
$query = "SELECT .... WHERE user_username='$user' AND user_password=md5('$pwd')";
which means, you could hack in by entering:
noob') or ('a'='a
for the password, giving you
SELECT .... AND user_password=md5('noob') or ('a'='a')
^^^^^^^^^^^^^^^^^-- your contribution
The actual password might not match, but 'a' will always equal itself, so the where clause will succeed and match a record based purely on the username and return the admin user's user_id.
A: As others had mentioned the escaping that you see is not the OS, but some form of encoding done in PHP (likely magic quotes, but could be a straight call to addslashes()).
Basically what you need to do is send in a form of quote that will not be escaped. You should research why one would use mysql_escape_string() rather than addslashes() and/or check this out: http://forums.hackthissite.org/viewtopic.php?f=37&t=4295&p=30747
A: Try ' OR 1; -- as user name. Imagine what the SQL query from such a user name looks like.
A: This has nothing to do with the operating system. The operating system simply runs the PHP package. PHP is what does sanitization, etc.
Have you tried submitting the following string for user_username?:
admin' OR 1=1-- #assuming mysql
Would yield a query:
select user_id from user where user_username = 'admin' OR 1=1 --' AND user_password = md5('noob')
In mysql (assuming the database type), -- is a comment, so everything after 1=1 is ignored. As a result, you've successfully gained access.
If php magic quotes are on, however, this will be slightly more difficult. You will need to submit characters outside of utf-8 or attempt overflows or submitting null bytes.
A: You could also try a bit of googling after entering a string that will error out the admin and use part of message that comes back as the key words.
You could also use the http://gray.cs.uni.edu/moodle/mod/forum/discuss.php?d=106 fourm to ask questions so the whole class can benifit!

if (file_attr & 0x10)
puts("FILE_ATTRIBUTE_DIRECTORY"); | unknown | |
d8286 | train | I finally remembered that the term for this is "chunking", and then I was able to track it down, in the itertools recipes no less. Boiled down, it's this head-spinning little trick with zip (actually zip_longest, but who's counting):
def chunk(source, n):
return zip_longest(*([iter(source)] * n))
First you take n references to the same iterator and bundle them into a list; then you unpack this list (with *) as arguments to zip_longest. When it's used, each tuple returned by zip_longest is filled from n successive calls to the iterator.
>>> for row in chunk(range(10), 3):
... print(row)
(0, 1, 2)
(3, 4, 5)
(6, 7, 8)
(9, None, None)
See the itertools recipes (look for grouper) and this SO answer for variations on the corner cases.
A: My suggestions is that, if you need such a function regularly, why not write it yourself. Here is an example how I would code it:
def slice_into_lists(iterable, groupsize):
rv = []
count = 0
for i in iterable:
rv.append(i)
count += 1
if count % groupsize == 0:
yield rv
rv = []
if rv:
yield rv
Of course instead of returning a list, you could also return something different.
A: The problem got me interested, so I worked on a solution that would not copy anything but only use the original iterator. Posting it here as it relates directly to the question.
class ichunk:
''' An iterable wrapper that raises StopIteration every chunksize+1'th call to __next__ '''
def __init__(self, iterable, chunksize, fill_last_chunk, fill_value):
self.it = iter(iterable)
self.stopinterval = chunksize+1
self.counter = 0
self.has_ended = False
self.fill_last = fill_last_chunk
self.fill_value = fill_value
def __iter__(self):
return self
def __next__(self):
if self.counter > 0 and self.counter % self.stopinterval == 0:
self.counter += 1
raise StopIteration
try:
self.counter += 1
nexti = next(self.it)
return nexti
except StopIteration as e:
self.has_ended = True
if (not self.fill_last) or (self.counter % self.stopinterval == 0):
raise e
else:
return self.fill_value
def ichunker(iterable, chunksize, *, fill_last_chunk=False, fill_value=None):
c = ichunk(iterable, chunksize, fill_last_chunk, fill_value)
while not c.has_ended:
yield c
So rather then using the returned value from ichunker, you iterate over it again like:
with open("filename") as fp:
for chunk in ichunker(fp, 10):
print("------ start of Chunk -------")
for line in chunk:
print("--> "+line.strip())
print("------ End of Chunk -------")
print("End of iteration")
A: Welcome to more_itertools.
Straight from the documentation:
>>> from more_itertools import ichunk
>>> from itertools import count
>>> all_chunks = ichunked(count(), 4)
>>> c_1, c_2, c_3 = next(all_chunks), next(all_chunks), next(all_chunks)
>>> list(c_2) # c_1's elements have been cached; c_3's haven't been
[4, 5, 6, 7]
>>> list(c_1)
[0, 1, 2, 3]
>>> list(c_3)
[8, 9, 10, 11]
You can choose between ichunk, which breaks an iterable into n sub-iterables, or chunk, which returns n sub-lists.
A: Use itertools.islice with enumerate like this
import itertools
some_long_string = "ajbsjabdabdkabda"
for n in itertools.islice(enumerate(some_long_string), 0, None ,10):
print(some_long_string[n[0]:n[0]+10])
# output
ajbsjabdab
dkabda
If you are dealing with file then you can use chunk while file.read() like this
# for file
with open("file1.txt", ) as f:
for n in itertools.islice(enumerate(f.read(10000)), 0, 1000 ,5):
print(n[1]) | unknown | |

d8292 | train | I'm not sure if I understand your question right, but to reduce boilerplate I would map your array to generate input fields:
render:function(){
var inputs = [];
this.props.form.fields.map(function(elem){
inputs.push(<Input data-fieldname={elem.fieldkey} type="text" label="Date Of Event" onChange={this.handleOnChange} value={elem.value} />);
});
return (<div className="row">
{inputs}
</div>)
}
This will always display your data in props. So when handleOnChange gets triggered the component will rerender with the new value. In my opinion this way is better than accessing a DOM node directly.
A: If you want to use dynamic information on the input, you need to pass it through the array, and make a loop.
Here is a little example based on Dustin code:
var fieldArray = [ //replace by this.props.form.fields
{
fieldkey: 'Signs and Symptoms',
value: 'fever, rash',
type: 'text',
label: 'Notes'
},
{
fieldkey: 'NotFeelingWell',
value: 'false',
type: 'checkbox',
label: 'Not Feeling Well'
},
];
var Fields = React.createClass({
handleOnChange:function(e){
var fieldKey = e.target.attributes['data-fieldname'].value;
Actions.updateField({
key: fieldKey,
value: e.target.value
})
},
render() {
var inputs = [];
fieldArray.map(function(field) { //replace by this.props.form.fields
inputs.push(
<Input
data-fieldname={field.fieldkey}

What is immediately popping out to me is this 'hGJfsdnk`1t'. The backward quote can be an escape character '`'. This could very well be throwing an error where error handling redirects back to the login page.
POSTMAN likely has something built in to render out the escape character to 'hGJfsdnk%601t'. Thus, this works in POSTMAN, but not in your code.

Here is shows the successful login.
A:
This is honestly one of weird sites I have seen in a long time. First thing was to know how it works. So I decided to use chrome and see what happens when we login with wrong data
Observations:
*
*Blanks username and passwords fields
*Generates SHA1 hashes of username and password fields and sets then in userNamedenc and respectively
*We can override username and password directly in JavaScript and login to your account just by overriding the details from console.
*There are lot of different request which generates cookies but none of them look any useful
So the approach to solve the issue was to follow below steps
*
*Get the login url login.do
*Fetch the form details from the response for the access code
*Submit the form to loginValidateUser.do
The form sends below parameters
Now one interesting part of the same is below post data
displayCaptcha:true
userEnteredCaptcha:strrty
If we override the displayCaptcha to false then captcha is no more needed. So a wonderful bypass
displayCaptcha: false
Next was to code all of the above in PHP, but the site seemed so weird that many of the attempts failed. So finally I realized that we need to take it a bit closer to the browser login and also I felt delays between calls are needed

}
After running the code it works few times and few times it doesn't. My observations
*
*Only one login is allowed at a time. So not sure if others were using the login when I was testing
*Without delays it would fail most of the time
*There is no obvious reason when it fails to login except the site doing something on server side to block the request

A: @yvesleborg and @tarun-lalwani gave the right hints. You need to take care of the cookies and the redirects. But nevertheless it was not working always for me. I guess the site operator requires some timeout between the two requests.
I rewrote your code a little bit to play around with it.
mycurl.php:
function my_curl_init() {
$url="http://www.mca.gov.in/mcafoportal/loginValidateUser.do";
$user_agent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36";
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
return $ch;
}
/*
* first call in order to get accessCode and sessionCookie
*/
$ch = my_curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, __DIR__ . "/cookie.txt"); // else cookielist is empty
$output = curl_exec($ch);
file_put_contents(__DIR__ . '/loginValidateUser.html', $output);
// save cookie info
$cookielist = curl_getinfo($ch, CURLINFO_COOKIELIST);
//print_r($cookielist);
curl_close($ch);
// parse accessCode from output
$re = '/\<input.*name="accessCode".*value="([-0-9]+)"/';
preg_match_all($re, $output, $matches, PREG_SET_ORDER, 0);
if ($matches) {
$accessCode = $matches[0][1];
// debug
echo "accessCode: $accessCode" . PHP_EOL;
/*
* second call in order to login
*/
$post_fields = array(
'userNamedenc' => 'hGJfsdnk`1t',
'passwordenc' => '675894242fa9c66939d9fcf4d5c39d1830f4ddb9',
'accessCode' => $accessCode
);
$cookiedata = preg_split('/\s+/', $cookielist[0]);
$session_cookie = $cookiedata[5] . '=' . $cookiedata[6];
// debug
echo "sessionCookie: $session_cookie" . PHP_EOL;
file_put_contents(__DIR__ . '/cookie2.txt', $session_cookie);
/*
* !!! pause !!!
*/
sleep(20);
// debug
echo "curl -v -L -X POST -b '$session_cookie;' --data 'userNamedenc=hGJfsdnk`1t&passwordenc=675894242fa9c66939d9fcf4d5c39d1830f4ddb9&accessCode=$accessCode' http://www.mca.gov.in/mcafoportal/loginValidateUser.do > loginValidateUser2.html";
$ch = my_curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
curl_setopt($ch, CURLOPT_COOKIE, $session_cookie);
$output = curl_exec($ch);
file_put_contents(__DIR__ . '/loginValidateUser2.html', $output);
curl_close($ch);
}
The script issues two request to the website. The output of the first one is used to read the accessCode and to store the session cookie. Then after a little break the second one is issued using the accessCode and session information together with the login credentials.
I tested it with PHP5.6 from a terminal (php -f mycurl.php). The script debugs all necessary information, outputs a curl command you could use in a terminal and logs the HTML and cookie information to some files in the same folder like the script.
Running the script too often doesn't work. The login won't work. So take your time and wait some minutes between your tries. Or change your IP ;)
Hope it helps.
A: Replication of the Problem
I did the same thing in Postman as you did your screenshot but was not able to log in:
The only difference I can see is that your request had cookies, which I suspect is why you were able to log in without all the other input fields. And it seems like there are quite a number of input fields:
Using Postman
So, I used postman intercept to capture all the fields used during a login, including the captcha and access code and I was able to login:
Update 1
I've found out that once you've solved a captcha to login, after you've logged out you may login again without displayCaptcha and userEnteredCaptcha in your form data, provided that you use the same cookie as the one you've used to login successfully. You just need to get a valid accessCode from the login page.
A: it doesnt work either in PHP/Python that is (as others have already pointed out) because you were using your browser's existing cookie session,
which had already solved the captcha. clear your browser cookies, get a fresh cookie session, and DO NOT SOLVE THE CAPTCHA, and Postman won't be able to log in either.
Any idea what is missing ? several things, among them, several post login parameters (browserFlag, loginType,__checkbox_dscBasedLoginFlag, and many more),
also your encoding loop here is bugged $str = $str . "$key=$value" . "&"; ,
it pretty much only works as long as both keys and values only contain [a-zA-Z0-9] characters,
and since your userNamedenc contains a grave accent character, your encoding loop is insufficient.
a fixed loop would be
foreach($params as $key=>$value){
$str = $str . urlencode($key)."=".urlencode($value) . "&";
}
$str=substr($str,0,-1);
, but
this is exactly why we have the http_build_query function, that entire loop and the following trim can be replaced with this single line:
$str=http_build_query($params);
, also, seems you're trying to login without a pre-existing cookie session,
that's not going to work. when you do a GET request to the login page, you get a cookie, and a unique captcha,
the captcha answer is tied to your cookie session, and needs to be solved before you attempt to login,
you also provide no code to deal with the captcha. also, when parsing the "userName" input element, it will default to "Enter Username", which is emtied with javascript and replaced with userNamedenc, you must replicate this in PHP,
also, it will have an input element named "dscBasedLoginFlag", which is removed with javascript, you must also do this part in php,
also it has an input element named "Cert", which has a default value, but this value is cleared with javascript, do the same in php,
and an input element named "newUserRegistration", which is removed with javascript, do that,
here's what you should do: make a GET request to the login page, save the cookie session and make sure to provide it for all further requests, and parse out all the login form's elements and add them to your login request (but be careful, there is 2x form inputs, 1 belong to the search bar, only parse the children of the login form, don't mix the 2), and remember to clear/remove the special input tags to emulate the javascript, as described above,
then make a GET request to the captcha url, make sure to provide the session cookie, solve the captcha,
then make the final login request, with the captcha answer, and userNamedenc and passwordenc and all the other elements
parsed out from the login page... that should work. now, solving the captcha programmatically,
the captha doesn't look too hard, cracking it probably can be automated, but until someone actually does that,
you can use Deathbycaptcha to do it for you, however note that it isn't a free service.
here's a fully tested, working example implementation, using my hhb_curl library (from https://github.com/divinity76/hhb_.inc.php/blob/master/hhb_.inc.php ), and the Deathbycaptcha api:

$parsedForms [$key1] [$key2] = $val2 [0];
}
}
}
return $parsedForms;
}
example usage: in terminal, write php foo.php | tee test.html, after a few seconds it will say something like:
the captcha is saved in /home/captcha.png
waiting for you to solve it by doing: echo ANSWER>/home/captcha.txt
then look at the captcha in /home/captcha.png , solve it, and write in another terminal: echo ANSWER>/home/captcha.txt, now the script will log in, and dump the logged in html in test.html, which you can open in your browser, to confirm that it actually logged in, screenshot when i run it: https://image.prntscr.com/image/_AsB_0J6TLOFSZuvQdjyNg.png
also note that i made 2 captcha solver functions, 1 use the deathbycaptcha api, and wont work until you provide a valid and credited deathbycaptcha account on line 5 and 6, which is not free, the other 1, solve_captcha2, asks you to solve the captcha yourself, and tells you where the captcha image is saved (so you can go have a look at it), and what command line argument to write, to provide it with the answer. just replace solve_captcha with solve_captcha2 on line 28, to solve it manually, and vise-versa. the script is fully tested with solve_captcha2, but the deathbycaptcha solver is untested, as my deathbycatpcha account is empty (if you would like to make a donation so i can actually test it, send 7 dollars to paypal account [email protected] with a link to this thread, and i will buy the cheapest deathbycaptcha credit pack and actually test it)

d8296 | train | your question is a little vague as to what the answer could be, did you want a value to return true if this is the case? did you want to gauruntee a way to fill the dictionary in a way where your condition is true?
if you want to check that your condition is true, try:
bool_dict = {}
for key, val in dict.items():
if max(val)-min(val)>x:
bool_list[key]=False
else: bool_dict[key]=True
print(bool_dict)
A: Here's my implementation:
def missions_to_dict(arr, x):
curr_key = 1
last_mission = arr[0]
dict = {"key1": [last_mission]}
# Loop through all missions
for curr_mission in arr[1:]:
# Check to see if current mission is x away from last mission
if abs(curr_mission - last_mission) <= x:
# Add it to same key as last mission
dict[f"key{curr_key}"].append(curr_mission)
# Otherwise, need to create new key
else:
curr_key += 1
dict[f"key{curr_key}"] = [curr_mission]
# Set current mission to last mission
last_mission = curr_mission
return dict | unknown | |
d8297 | train | To get the browser name, you can use browser.getCapabilities():
browser.getCapabilities().then(function(capabilities) {
// Outputs 'chrome' when on Chrome
console.log(capabilities.caps_.browserName);
});
If waiting until a promise is resolved isn't good for your use case, then a hackier way that works on my system is to access the resolved/fulfilled session object directly:
// Outputs 'chrome' when on Chrome
console.log(browser.driver.session_.value_.caps_.caps_.browserName); | unknown | |
d8298 | train | You can add a with_items loop taking a list to every task in the imported file, and call import_tasks with a variable which you pass to the inner with_items loop. This moves the handling of the loops to the imported file, and requires duplication of the loop on all tasks.
Given your example, this would change the files to:
playbook.yml
---
- hosts: 192.168.33.100
gather_facts: no
tasks:
- import_tasks: msg.yml
vars:
messages:
- 1
- 2
msg.yml
---
- name: Message 1
debug:
msg: "Message 1: {{ item }}"
with_items:
- "{{ messages }}"
- name: Message 2
debug:
msg: "Message 2: {{ item }}"
with_items:
- "{{ messages }}"
A: It is not possible. include/import statements operate with task files as a whole.
So with loops you'll have:
Task 1 with Item 1
Task 2 with Item 1
Task 3 with Item 1
Task 1 with Item 2
Task 2 with Item 2
Task 3 with Item 2
Task 1 with Item 3
Task 2 with Item 3
Task 3 with Item 3 | unknown | |
d8299 | train | The error message says you have a byte 0x92 in your file somewhere, which is not valid in utf-8, but in other encodings it may be, for example:
>>> b'\x92'.decode('windows-1252')
'`'
That means that your file encoding is not utf-8, but probably windows-1252, and problematic character is the backtick, not the dot, even if that character is found only in a comment.
So either change your file encoding to utf-8 in your editor, or the encoding line to
# -*- coding: windows-1252 -*-
The error message doesn't mention the file the interpreter choked on, but it may be your "main" file, not socket.py.
Also, don't name your file socket.py, that will shadow the builtin socket module and lead to further errors.
Setting an encoding line only affects that one file, you need to do this for every file, only setting it in your "main" file would not be enough.
A: Your error says 'utf8' codec can't decode byte 0x92". In the Windows codepage 1252, this character maps to U+2019 the right quotation mark ’.
It is likely that the editor you use for your Python script is configured to replace the single quote ('\x27' or ') by the right quotation mark. It may be nicer for text, but is terrible in source code. You must fix it in your editor, or use another editor.
A: Thank you ! Indeed, this character doesn't exist in utf-8.
However, I didn't send the character "`", corresponding to 0x92 with windows-1252 and to nothing in utf-8. Futhermore this error appears when a character "." is in controlAddr and it is the same hexadecimal code for both encoding, i.e, 0x2e.

d8300 | train | After try and fails finally, solved this issue.
Rethink the code for FrameDelimiterDecoder and found the way how to do it with an array of bytes and at the end convert to ByteBuf. I believe it could be done with the buffer directly or to use ByteBuffer from NIO package and then convert.
The simplest for me was:
@Slf4j
public class FrameDelimiterDecoder extends DelimiterBasedFrameDecoder {
public FrameDelimiterDecoder(int maxFrameLength, ByteBuf delimiter) {
super(maxFrameLength, delimiter);
}
@Override
protected Object decode(ChannelHandlerContext ctx, ByteBuf buffer) {
boolean inMessage = false;
int size = buffer.readableBytes();
ByteBuffer byteBuffer = ByteBuffer.allocate(size);
buffer.readBytes(byteBuffer);
byte[] byteArray = new byte[size - 2];
byte[] data = byteBuffer.array();
int index = 0;
for (byte b : data) {
if (b == FrameConstant.START_OF_TEXT) {
if (!inMessage) {
inMessage = true;
} else {
log.warn("Unexpected STX received!");
}
} else if (b == FrameConstant.END_OF_TEXT) {
if (inMessage) {
inMessage = false;
} else {
log.warn("Unexpected ETX received!");
}
} else {
if (inMessage) {
byteArray[index] = b;
index += 1;
}
}
}
return Unpooled.wrappedBuffer(byteArray);
}
@Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) {
if (cause instanceof InterruptedException) {
log.warn("interrupted exception occurred");
Thread.currentThread().interrupt();
} else {
log.error("FrameDelimiterEncoder exception occurred:", cause);
}
}
}
Where FrameConstant look like:
@UtilityClass
public class FrameConstant {
public final int START_OF_TEXT = 0x02;
public final int END_OF_TEXT = 0x03;
public final int MAX_FRAME_LENGTH = 1024 * 1024;
}
Then initialize it:
@Slf4j
@Component
@RequiredArgsConstructor
public class QrReaderChannelInitializer extends ChannelInitializer<SocketChannel> {
private final StringEncoder stringEncoder = new StringEncoder();
private final StringDecoder stringDecoder = new StringDecoder();
private final QrReaderProcessingHandler readerServerHandler;
private final NettyProperties nettyProperties;
@Override
protected void initChannel(SocketChannel socketChannel) {
ChannelPipeline pipeline = socketChannel.pipeline();
// Add the delimiter first
pipeline.addLast(getDelimiterDecoder());
if (nettyProperties.isEnableTimeout()) {
pipeline.addLast(new ReadTimeoutHandler(nettyProperties.getClientTimeout()));
}
pipeline.addLast(stringDecoder);
pipeline.addLast(stringEncoder);
pipeline.addLast(readerServerHandler);
}
private FrameDelimiterDecoder getDelimiterDecoder() {
ByteBuf delimiter = Unpooled.wrappedBuffer(new byte[]{FrameConstant.END_OF_TEXT});
return new FrameDelimiterDecoder(FrameConstant.MAX_FRAME_LENGTH, delimiter);
}
}
And some modification for handler:
@Slf4j
@Component
@RequiredArgsConstructor
@ChannelHandler.Sharable
public class QrReaderProcessingHandler extends ChannelInboundHandlerAdapter {
private final PermissionService permissionService;
private final EntranceService entranceService;
private final Gson gson;
@Override
public void channelRead(ChannelHandlerContext ctx, Object msg) {
String remoteAddress = ctx.channel().remoteAddress().toString();
String stringMsg = (String) msg;
if (log.isDebugEnabled()) {
log.debug("CLIENT_IP: {}", remoteAddress);
log.debug("CLIENT_REQUEST: {}", stringMsg);
}
if (HEARTBEAT.containsName(stringMsg)) {
HeartbeatResponse heartbeatResponse = buildHeartbeatResponse();
sendResponse(ctx, heartbeatResponse);
}
}
private <T> void sendResponse(ChannelHandlerContext ctx, T response) {
ctx.writeAndFlush(formatResponse(response));
}
private <T> String formatResponse(T response) {
String realResponse = String.format("%s%s%s",
(char) FrameConstant.START_OF_TEXT,
gson.toJson(response),
(char) FrameConstant.END_OF_TEXT);
log.debug("response: {}", realResponse);
return realResponse;
}
And finally, it sends correctly formed response back: | unknown |
