A: You can avoid the "Failed to get D-Bus connection: Operation not permitted" / aka installing systemd inside a docker by using the https://github.com/gdraheim/docker-systemctl-replacement ... after that the docker-exec stuff should be all fine to do things inside a container.
A: If you really do need an ssh or sftp container, then you can use my Docker Image as a source image for your own or run it directly:
If using the official CentOS-7 Image and you require systemd, there are instructions on how to enable it under the section "Systemd integration".
However, based on the following:
I need to ssh in to the docker container(CentOS 7) from my host.
You can use docker exec to run commands in a running, (backgrounded), container so, for images that have bash available, you can access an interactive tty and run bash as follows from your host - where container can be either the name or id:
docker exec --tty --interactive <container> bash
OR
docker exec -ti <container> bash
Finally, it's unlikely to be necessary to install the firewall package in your image as the operator will decide what ports to publish from those which are exposed and you can make use of Docker Networking to only expose the necessary public facing services.
A: If you are using the Docker CLI, then you can get into the Docker container using the following command
docker exec -it containerId bash
I am not sure how to ssh into the docker container, but if you want to do basic operation inside the Docker container, you can make use of the above docker command. | unknown | |
d18506 | test | You don't give much detail as to why.
This happens in the Dispose override method of the form (in form.designer.cs). It looks like this:
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
A: Both the Panel and the Form class have a Controls collection property, which has a Clear() method...
MyPanel.Controls.Clear();
or
MyForm.Controls.Clear();
But Clear() doesn't call dispose() (All it does is remove he control from the collection), so what you need to do is
List<Control> ctrls = new List<Control>(MyPanel.Controls);
MyPanel.Controls.Clear();
foreach(Control c in ctrls )
c.Dispose();
You need to create a separate list of the references because Dispose also will remove the control from the collection, changing the index and messing up the foreach...
A: I don't believe there is a way to do this all at once. You can just iterate through the child controls and call each of their dispose methods one at a time:
foreach(var control in this.Controls)
{
control.Dispose();
}
A: You didn't share if this were ASP.Net or Winforms. If the latter, you can do well enough by first calling SuspendLayout() on the panel. Then, when finished, call ResumeLayout(). | unknown | |

d18508 | test | Yes, it's bad practice to put any personal information in the URL. A URL can be cached and viewed in so many ways. Even if you use SSL, URLs are still saved in your browser's history, so it just makes me cringe to pass non-public data in the URL. Usually it's not any more work to pass information in the body of a POST request, so that's what I would do.
A: Not if you do it over https, as the URL path and querystring will be encrypted along with the body.
It's not a problem for the URL to be stored in the browser history, as that is private to the user. | unknown | |
d18509 | test | It turns out this is an IE bug (no real surprise there) - when the browser spawns a new tab in a new worker process the new process doesn't have access to the session cookie. A few other people have found this and stopping the spawning of new processes, though not a great solution, seems to fix the issue. Note that this issue also occurs on the Yahoo website, and all other sites that use session cookies. Really not sure which combination of events and situations trigger this (on our system is only hits non-admin users - we've looked through our GPO rules but haven't found anything obvious), but I reckon MS really need to fix it because if it starts to trigger more often it could completely cripple IE.
Here's the link to temporarily bypass the issue, if you get hit by it, yourself.

d18513 | test | You've got 2 choices:
*
*Put the library jar on the
classpath.
*Assemble\Build the library jar with
the regular jar.
For option 1, you most likely need the jar located "near" the main jar on the file system; though, this is not necessarily a requirement. When you run the jar you then include the library jar on the classpath.
For option 2, you use some type of tool like maven's assembly plugin or the fatjar plugin in Eclipse (sorry, I don't know what the analog is in NB).
I hope this helps. | unknown | |
d18514 | test | You are simply: writing as string, but reading back expecting a binary serialized object!
You know, that is like: you put an egg in a box, and then you expect you can open that box and pour milk from it into a glass! That wont work.
Here:
bw.write(m.toString());
You write the map into that file as raw string. This means that your file now contains human readable strings!
But then you do:
Map<String, String> myMap=(LinkedHashMap<String, String>) is.readObject();
Which expects that the file contains serialized objects.
Long story short, these are your options:
*
*keep writing these strings, but then you need to implement your own parser that reads such text files, and turns them back into objects within maps
*instead of writing raw text strings, use a library such as gson or jackson and serialize your map as JSON string (which requires that all keys/values can be serialized as JSON)
*instead of writing raw text or JSON, use the default Java serialization mechanism and serialize to binary content which requires that all keys/values implement the Serializable interface. See here for a nice tutorial how to do that in detail.
My recommendation: go for option 2, or 3. 2 adds a dependency to a 3rd party library, but I think it is the more "common" practice these days.
A: You need to serialize/deserialize the object, not just reading/writing its toString representation to file.

d18515 | test | Let's think of your problem this way: You have a set of balls in 64-dimension space each with radius d, representing the space around each of your input vectors. (Note, I'm assuming that by "distance" you mean Euclidean distance).
Now, you want to find the smallest subset of balls that will cover each of your original points, meaning that you need each point to be inside at least one ball in the subset, with the additional restriction that the balls in the cover must have centers also distance d apart.
Without this additional restriction, you have an instance of a hard but well-studied one called Geometric set cover, which in turn is a special case of the more famous Set cover problem. It seems intuitively that the additional restriction makes the problem harder, but I don't have a proof for that.
The bad news is, the (geometric) set cover problem is NP-hard, meaning that you won't be able to quickly find the exact minimum if there may be many points in the original set.
The good news is, there are good algorithms that find approximate solutions, which will give you a set which isn't necessarily as small as possible, but which is close to the smallest possible.
Here is Python code for a simple greedy algorithm which will not always find a minimum-size cover, but will always return a valid one:
def greedy(V, d):
cover = set()
uncovered = set(V)
# invariant: all(distance(x,y) > d for x in cover for y in uncovered)
while uncovered:
x = uncovered.pop()
cover.add(x)
uncovered = {y for y in uncovered if distance(x,y) > d}
Note, you could make this greedy solution a little better by replacing the uncovered.pop() call with a smarter choice, for example choosing a vector which would "cover" the most number of remaining points.
A: First, we can derive an undirected graph where vertices are the vectors of v and edges are the pairs of points that are no farther apart than r. This doesn't require the distances to be a proper metric: it doesn't have to satisfy the triangle inequality, only that it is symmetrical (dist(a,b) == dist(b,a)) and that it is 0 iff two points are equal.
After that step, we can forget about the distances altogether and focus entirely on partitioning the graph. As others have noted, that partition is a Vertex Cover problem. However, it has a twist: we require all the vertices in the cover to be disjoint (i.e.: no vectors in v1 can be within distance r of each other).
To obtain the graph, we can use the efficient KDTree to compute just once the nearest-neighbor structure. In particular, we'll use kd.sparse_distance_matrix(kd, r) to obtain all pairs of points separated by r or less:
from scipy.spatial import KDTree
def get_graph(v, r):
kd = KDTree(v)
sm = kd.sparse_distance_matrix(kd, r)
graph = {i: {i} for i, _ in sm.keys()}
for i, j in sm.keys():
graph[i] |= {j}
return graph
(note: .sparse_distance_matrix() has a parameter p if we want other distances than Euclidean).
The partitioning of the graph can be done in various ways. @DanR shows a greedy approach that is very fast, but often suboptimal in the size of v1 that it finds.
The following shows instead a brute-force approach that is guaranteed to find a minimal solution if there is one. It is adequate for relatively small number of vectors and can provide a ground-truth for the optimal solution, when researching other heuristics.
To speed up the combinatorial search, we first observe that often some points are not within distance r of any other (i.e. the graph found above doesn't represent all the points of v). We can leave those other points aside, since they will necessarily be part of v1 but don't interfere with the rest of the search (below, we call them "singletons"). Second, we cut unpromising "leads" (prefixes in the combinatorial expansion) if they are not fully disjoint. This speeds up considerably the full search, by cutting down entire swathes of search space. If no prefix is cut, the full search is time-exponential.
What is the speed of this? It depends on the distribution of the v vectors and (strongly) on the distance r. In fact, it depends on the number of clusters found. To give an idea, with v 20 vectors picked in uniform in 2D, I observe roughly 30ms. For 40 vectors, typically around 100ms, but it can jump to over 2 seconds for certain values of r.
We implement a variation of combinations that has a check function to cut down unpromising prefixes:
from itertools import combinations
def _okall(tup, *args, **kwargs):
return True
def combinations_all(iterable, n0=1, n1=None, check=None, *args, **kwargs):
pool = tuple(iterable)
n = len(pool)
if n0 > n:
return
n1 = n if n1 is None else n1
check = _okall if check is None else check
if n0 < 1:
yield ()
n0 = 1
seed = list(combinations(range(n), n0-1))
for r in range(n0, n1+1):
prev_seed = seed
seed = []
for prefix in prev_seed:
for j in range(max(prefix, default=-1)+1, n):
indices = prefix + (j,)
tup = tuple(pool[i] for i in indices)
if check(tup, *args, **kwargs):
seed.append(indices)
yield tup
Example:
# list all combinations of [0,1,2,3] (of all sizes), excluding those starting
# by (0,1)
>>> list(combinations_all(range(4), check=lambda tup: tup[:2] != (0,1)))
[(0,),
(1,),
(2,),
(3,),
(0, 2),
(0, 3),
(1, 2),
(1, 3),
(2, 3),
(0, 2, 3),
(1, 2, 3)]
Now, we use that to find the minimal disjoint cover and return the indices of v1:
def check(tup, graph):
# refuses tup if any one is within reach of another
# optimization: tup[:-1] has already passed this test, so just check the last one
if len(tup) < 2:
return True
reach_of_last = graph[tup[-1]]
prefix = set(tup[:-1])
return prefix.isdisjoint(reach_of_last)
def brute_vq(v, r):
n = v.shape[0]
graph = get_graph(v, r)
to_part = set(graph)
singletons = set(range(n)).difference(to_part)
if not to_part:
return sorted(singletons)
for tup in combinations_all(to_part, check=check, graph=graph):
# here tup are indices that are far apart enough (guaranteed disjoint in reach)
# check if they fully cover to_part
cover = {j for i in tup for j in graph[i]}
if cover == to_part:
v1_idx = sorted(singletons.union(tup))
return v1_idx
Examples:
v = np.random.uniform(size=(20, 2))
r_s = [[0.2, 0.3], [0.4, 0.5]]
fig, axes = plt.subplots(nrows=len(r_s), ncols=len(r_s[0]),
figsize=(12,12), sharex=True, sharey=True)
for r, ax in zip(np.ravel(r_s), np.ravel(axes)):
idx = brute_vq(v, r)
ax.set_aspect('equal')
ax.scatter(v[:, 0], v[:, 1])
for i, p in enumerate(v):
ax.text(*p, str(i))
for i in idx:
circ = plt.Circle(v[i], radius=r, color='g', fill=False)
ax.add_patch(circ)
plt.show();

A: When the site is encrypted squid can validate only the Domain but not the entire URL path or keywords in the URL.

d18520 | test | I would put all of your functions and variables into a single object for your library.
var MyLibrary = {
myFunc: function() {
//do stuff
},
myVar: "Foo"
}
There are a few different ways of defining 'classes' in JavaScript. Here is a nice page with 3 of them.
A: You should take one variable name in the global namespace that there are low odds of being used, and put everything else underneath it (in its own namespace).
For example, if I wanted to call my library AzureLib:
AzureLib = {
SortSomething: function(arr) {
// do some sorting
},
DoSomethingCool: function(item) {
// do something cool
}
};
// usage (in another JavaScript file or in an HTML <script> tag):
AzureLib.SortSomething(myArray);
A: You could put all of your library's functions inside of a single object. That way, as long as that object's name doesn't conflict, you will be good. Something like:
var yourLib = {};
yourLib.usefulFunction1 = function(){
..
};
yourLib.usefulFunction2 = function(){
..
};
A: Yes, you can create an object as a namespace. There are several ways to do this, syntax-wise, but the end result is approximately the same. Your object name should be the thing that no one else will have used.
var MyLibrary = {
myFunc: function() { /* stuff */ }
};
Just remember, it's object literal syntax, so you use label : value to put things inside it, and not var label = value;.
If you need to declare things first, use a wrapping function to enclose the environment and protect you from the global scope:
var MyLibrary = (function() {
var foo = 'bar';
return {
myFunc: function() { /* stuff */ }
};
})(); // execute this function right away to return your library object | unknown | |

df = pd.read_csv(Location2, sep=';')
Sample:
import pandas as pd
from pandas.compat import StringIO

#after testing replace 'StringIO(temp)' to 'filename.csv'
df = pd.read_csv(StringIO(temp), sep=";")

d18523 | test | The API call windows.remove() is specifically for closing a window. You will need the windowId, which is available as the id property within the windows.Window Object which is passed to the callback/resolve function for windows.create().
You do not need to call windows.remove() from the same script which opened the window. Any script with access to that API can close the window.
A: You can remove a window created by an extension in Firefox from a "dismiss" button this way:
GetEl('dismiss').addEventListener('click',function(e)
{
browser.windows.getCurrent().then(F2);
});
function F2(info)
{
return browser.windows.remove(info.id);
} // F2
(GetEl returns the element node for a given id string.) | unknown | |
d18524 | test | The problem is that rendering (transformation to an OutgoingContent) of a request body happens during the execution of the HttpRequestPipeline, which takes place only once after making an initial request. The HTTP request retrying happens after in the HttpSendPipeline.
Since you pass a String as a request body it needs to be transformed before the actual sending. To solve this problem, you can manually wrap your String into the TextContent instance and pass it to the setBody method:
retry {
retryOnServerErrors(maxRetries = Int.MAX_VALUE)
exponentialDelay(maxDelayMs = 128.seconds.inWholeMilliseconds)
modifyRequest {
it.setBody(TextContent("With Different body ...", ContentType.Text.Plain))
}
} | unknown | |
d18525 | test | lFirst does not have any aggregate function (MAX, MIN, SUM, COUNT...) so there is no need to have a GROUP BY clause. Do not confuse between DISTINCT row operator and GROUP BY clause.
Second, "BY EMP_PERSONAL.NEW_EMPNO DESC" Does not mean anything ! Is it a compement to GROUP BY or a part of ORDER BY ?
To solve the first part, rewrite your query as :
SELECT FIRST_NAME, MIDDLE_NAME,LAST_NAME , EMP_MOBILE_NO,NEW_EMPNO , SECTION_NAME, EMP_TYPE, JOINING_DATE
FROM EMP_OFFICIAL,EMP_PERSONAL
WHERE EMP_PERSONAL.STATUS='Active'
AND EMP_OFFICIAL.WORK_ENT='Worker'
AND EMP_OFFICIAL.EMPNO=EMP_PERSONAL.EMPNO
Also a JOIN must be write with the JOIN operator not as a cartesian product followed by a restriction. So rewrite your query as :
SELECT FIRST_NAME, MIDDLE_NAME,LAST_NAME , EMP_MOBILE_NO,NEW_EMPNO , SECTION_NAME, EMP_TYPE, JOINING_DATE
FROM EMP_OFFICIAL
JOIN EMP_PERSONAL
ON EMP_OFFICIAL.EMPNO=EMP_PERSONAL.EMPNO
WHERE EMP_PERSONAL.STATUS='Active'
AND EMP_OFFICIAL.WORK_ENT='Worker'
This will be most optimized by the optimizer because it not spread time and operations to do the translation between false JOIN and real joins... | unknown | |
d18526 | test | You need to actually create the table first, then run your code to populate the table. I would take a look at the data set you're working with to get an idea of the field names and data types and then run something like this:
CREATE TABLE devices(
id serial PRIMARY KEY,
name TEXT NOT NULL,
otherfield TEXT NOT NULL
);
I'm not sure if you're trying to build a full automated cycle of creating a table and populating it, but you could just hop on over to postgres and run the create table code in the terminal or whatever database management tool you're using. After the table is created, you should be table to run the below code to verify it's been created correctly:
SELECT * FROM devices
It should come back with an empty table with all the columns you specified. If all that is good to go, run your code that populates the table. Should work fine. | unknown | |
d18527 | test | This seems to be a case when we need to apply a logic on column values before a record is inserted. I would suggest creating a BEFORE INSERT trigger on this table, which will be automatically executed by MySql before each record is inserted.
We can write the logic to determine the value of last column depending upon values supplied for the other columns. Have a look at this link for trigger example.
If the requirement here is to do a one time bulk insert then, we can drop this trigger once insertion is complete.
A: I would advise you to do it either with BEFORE INSERT trigger as Darshan Mehta recommends, or do your logic in the programming side, or with a stored procedure.
Still it is doable at query time, so to answer your question specifically, try something like this:
INSERT INTO medicos (num_colegiado, apellidos, especialidad, fecha_nac, universidad, sueldo, tipo_medico) SELECT 'A021', 'Apellidos :D', 'Loquesealogia', '1970-03-14', 'Valencia', '3500', IF('Loquesealogia' like '%a','Excellent',IF(DATE_ADD('1970-03-14', interval 40 YEAR)>NOW(),'Expert','indiferente')) | unknown | |

To keep from having a whole lot of maintenance, instead of listing each user individually, what we did was just pared down the list from "Valid Users" to the "Moderators" and "Contributors". We know that we can control those groups without affecting service permissions:

d18529 | test | One way to make code available across different script scopes is to use a WinJS namespace.
For example, in page1.js, you would have:
(function(){
function setText(){
var mytext = "";
WinJS.Namespace.define("page1", {
text: mytext
});
}
})();
in page2.js, you'd put the text in that namespace:
(function(){
page1.text = "page 2 text!";
})();
Back in page 1, you can retrieve that value later on:
(function(){
function setText(){
var mytext = "";
WinJS.Namespace.define("page1", {
text: mytext
});
}
function getText() {
document.querySelector("#myTextField").value = page1.text;
}

I'd suggest being a bit more formal about what you put in namespaces, but that's one way to do it. | unknown | |

d18531 | test | As Evert said, the commit() was missing. An alternative to always specifying it in your code is using the autocommit feature.
http://initd.org/psycopg/docs/connection.html#connection.autocommit
For example like this:
with psycopg2.connect("...") as dbconn:
dbconn.autocommit=True
A: You forgot to do connection.commit(). Any alteration in the database has to be followed by a commit on the connection. For example, the sqlite3 documentation states it clearly in the first example:
# Save (commit) the changes.
conn.commit()
And the first example in the psycopg2 documentation does the same:
# Make the changes to the database persistent
>>> conn.commit() | unknown | |
d18532 | test | You can pass the setOpen function as a prop to the SidebarButton component and then simply call the setOpen function to change the value.
<SidebarButton setOpen={setOpen} />
If you would like to also call it from the menu component then you may need to move the declaration of open to a higher component that is common between Sidebar and Menu since props can only be passed downwards. | unknown | |
d18533 | test | Make sure that MySQL.Data.dll actually got copied to the output folder. And that you are using right platform (x32 vs x64 bit) and right version of .NET (2,3,3.5 vs 4). If everyhing seems fine, enable Fusion Logging and take a look at this article:
For FileNotFoundException: At the bottom of the log will be the paths
that Fusion tried probing for this assembly. If this was a load by
path (as in Assembly.LoadFrom()), there will be just one path, and
your assembly will need to be there to be found. Otherwise, your
assembly will need to be on one of the probing paths listed or in the
GAC if it's to be found.
You may also get this exception if an unmanaged dependency or internal
module of the assembly failed to load. Try running depends.exe on the
file to verify that unmanaged dependencies can be loaded. Note that if
you re using ASP.NET, the PATH environment variable it's using may
differ from the one the command line uses. If all of them could be
loaded, try ildasm.exe on the file, double-click on "MANIFEST" and
look for ".file" entries. Each of those files will need to be in the
same directory as the manifest-containing file. | unknown | |
d18534 | test | Note that Ajax request are usually sent through the client's browser, while usually a server would call file_get_contents() or a similar tool, to fetch your page.
So in the case of a server, you can check the REMOTE_ADDR HTTP header (which contains the caller's IP) against a blacklist.
In the case of an Ajax request, probably from a user agent you can't really say from which website the originated from.
Though I am not sure, but the HTTP_REFERER header might contain exactly that, but again I have not checked it.
UPDATE (Ajax Requests):
After looking up a little bit, I turn out that browsers don't send referrer data with XHR requests, so you can only blacklist the IPs of the servers you don't want to be accessed from.
A: If the server request it directly then you can use $_SERVER 'REMOTE_ADDR' and 'REMOTE_HOST'.
If they use javascript then you will only get the clients ip. You can use strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') to disallow jquery requests.
A: Isn't what you're looking for a $_SERVER['REMOTE_ADDR']? AJAX calls probably won't have a Referer header and that's why you are getting that error.
A: The HTTP Referrer gets sent by a browser, probably not by file_get_contents()!
You can use $_SERVER['REMOTE_ADDR']. This will give you the raw IP address from the TCP stack.
In the case of a server-side API call, you get the server's IP (assuming the client does not use any proxies).
However if the client is an AJAX request, you'll get the IP address of the user viewing that page.
A: HTTP_REFERER is not going to be reliable. You might try $_SERVER['REMOTE_ADDR'] to inspect IP address of remote client.
I would however think that you would have a better time whitelisting approved clients rather then blacklisting, as an attacker could easily proxy a request to get around an IP/host-based blacklist.
There are a number of approaches for whiltelisting:
*
*whitelist known IP's
*HTTP Authentication
*Your own custom API keys
*Third party authentication (i.e. OAuth)
and so forth. | unknown | |
d18535 | test | If I see... you can use ScrollTo method.
yourLongListMultiSelector.ScrollTo(yourNewInsertedItem);
A: To get you going, I tried something but could not get it a 100%
Here is a working basic page template which in fact does what you require with messages
<phone:PhoneApplicationPage >
<ScrollViewer x:Name="Scroll" VerticalAlignment="Bottom" Height="500" ScrollViewer.VerticalScrollBarVisibility="Disabled">
<StackPanel VerticalAlignment="Bottom" >
<toolkit:LongListMultiSelector x:Name="DataList" ItemsSource="{Binding}" ScrollViewer.VerticalScrollBarVisibility="Disabled" VerticalAlignment="Bottom"
VirtualizingStackPanel.VirtualizationMode="Recycling"></toolkit:LongListMultiSelector>
</StackPanel>
</ScrollViewer>
</phone:PhoneApplicationPage>
This keeps new messages down, pulling the list up. The scrolling is now disabled. You can easily enclose ScrollViewer in grid and add the button above (like in your picture)
Now the code that would go into the button click
Scroll.VerticalScrollBarVisibility = ScrollBarVisibility.Hidden;
Scroll.ScrollToVerticalOffset(DataList.ActualHeight);
Unfortunately this scrolls the list up BUT if you trigger the second line of code again for example via button click, ScrollToVerticalOffset works. So for some reason ScrollToVerticalOffset is not working right away-after changing VerticalScrollBarVisibility. If you can get this last part figured out, I believe your question would be solved
A: The thing that prevents your desired effect is the ListHeader control is at top when you insert item at top. You can do some tricky code to bypass it:
var temp = MyLongListMultiSelector.ListHeader; //also works with ListHeaderTemplate
MyLongListMultiSelector.ListHeader = null;
MyObservableCollection.Insert(0, item);
MyLongListMultiSelector.ListHeader = temp;
Or you can make a fake header item and handle the add top event like:
MyLongListMultiSelector.Remove(fakeHeaderItem);
MyObservableCollection.Insert(0, item);
MyObservableCollection.Insert(0, fakeHeaderItem);
A: you can easily achieve this via adding new items to top of the observable collection
obsData.Insert(0,newItem)

public_dependency appears to include object IDs for objects you don't have permissions on. The objecct IDs on their own don't tell you much, so it isn't revealing anything about objects you can't see (other than that there are some objects you can't see).
So it isn't odd that there is an apparent discrepancy between what the two views reference. Querying all_dependencies might give you a more comsistent picture. | unknown | |

d18539 | test | If you do this:
Object **c = new Object*[n];
for (size_t i=0; i!=n; ++i) {
c[i] = new Object[m];
}
then it will typically take more memory than doing this:
Object *c = new Object[n*m];
for just the reasons you stated.
Every memory allocation has a certain amount of overhead. In addition to needing to keep the number of elements, there is overhead for the memory allocator itself. It also takes more memory for all the extra pointers for each row.
Note that it is possible to have a situation where breaking it up would use less memory. If your heap was fragmented, then finding one large chunk of memory may require allocating more memory from the operating system, whereas if your array was broken into smaller pieces, those pieces may be able to fit in the holes of your fragmented heap. | unknown | |

d18545 | test | This took me quite a long time to answer since I had to create my own format currency function.
A live demo can be found here: http://jsfiddle.net/dm6LL/
The basic updating each second is very easy and will be done through JavaScript's setInterval command.
setInterval(function(){
current += .158;
update();
},1000);
The update() function you see in the above code is just a simple updater referencing an object with the amount id to put the formatted current amount into a div on the page.
function update() {
amount.innerText = formatMoney(current);
}
Amount and current that you see in the update() function are predefined:
var amount = document.getElementById('amount');
var current = 138276343;
Then all that's left is my formatMoney() function which takes a number and converts it into a currency string.
function formatMoney(amount) {
var dollars = Math.floor(amount).toString().split('');
var cents = (Math.round((amount%1)*100)/100).toString().split('.')[1];
if(typeof cents == 'undefined'){
cents = '00';
}else if(cents.length == 1){
cents = cents + '0';
}
var str = '';
for(i=dollars.length-1; i>=0; i--){
str += dollars.splice(0,1);
if(i%3 == 0 && i != 0) str += ',';

A: $myarray = array_filter($myarray, 'strlen'); //removes null values but leaves "0"
$myarray = array_filter($myarray); //removes all null values
A: foreach($arr as $key => $val){
if (empty($val)) unset($arr[$key];
}
A: Just one line :
Update (thanks to @suther):
$array_without_empty_values = array_filter($array);
A: You can just do
array_filter($array)
array_filter: "If no callback is supplied, all entries of input equal to FALSE will be removed." This means that elements with values NULL, 0, '0', '', FALSE, array() will be removed too.
The other option is doing
array_diff($array, array(''))
which will remove elements with values NULL, '' and FALSE.
Hope this helps :)
UPDATE
Here is an example.
$a = array(0, '0', NULL, FALSE, '', array());
var_dump(array_filter($a));
// array()
var_dump(array_diff($a, array(0))) // 0 / '0'
// array(NULL, FALSE, '', array());
var_dump(array_diff($a, array(NULL))) // NULL / FALSE / ''
// array(0, '0', array())
To sum up:
*
*0 or '0' will remove 0 and '0'
*NULL, FALSE or '' will remove NULL, FALSE and ''
A: foreach($linksArray as $key => $link)
{
if($link === '')
{
unset($linksArray[$key]);
}
}
print_r($linksArray);
A: In short:
This is my suggested code:
$myarray = array_values(array_filter(array_map('trim', $myarray), 'strlen'));
Explanation:
I thinks use array_filter is good, but not enough, because values be like space and \n,... keep in the array and this is usually bad.
So I suggest you use mixture array_filter and array_map.
array_map is for trimming, array_filter is for remove empty values, strlen is for keep 0 value, and array_values is for re indexing if you needed.
Samples:
$myarray = array("\r", "\n", "\r\n", "", " ", "0", "a");
// "\r", "\n", "\r\n", " ", "a"
$new1 = array_filter($myarray);
// "a"
$new2 = array_filter(array_map('trim', $myarray));
// "0", "a"
$new3 = array_filter(array_map('trim', $myarray), 'strlen');
// "0", "a" (reindex)
$new4 = array_values(array_filter(array_map('trim', $myarray), 'strlen'));
var_dump($new1, $new2, $new3, $new4);
Results:
array(5) {
[0]=>
" string(1) "
[1]=>
string(1) "
"
[2]=>
string(2) "
"
[4]=>
string(1) " "
[6]=>
string(1) "a"
}
array(1) {
[6]=>
string(1) "a"
}
array(2) {
[5]=>
string(1) "0"
[6]=>
string(1) "a"
}
array(2) {
[0]=>
string(1) "0"
[1]=>
string(1) "a"
}

A: Another one liner to remove empty ("" empty string) elements from your array.
$array = array_filter($array, function($a) {return $a !== "";});
Note: This code deliberately keeps null, 0 and false elements.
Or maybe you want to trim your array elements first:
$array = array_filter($array, function($a) {
return trim($a) !== "";
});
Note: This code also removes null and false elements.
A: use array_filter function to remove empty values:
$linksArray = array_filter($linksArray);
print_r($linksArray);
A: Remove empty array elements
function removeEmptyElements(&$element)
{
if (is_array($element)) {
if ($key = key($element)) {
$element[$key] = array_filter($element);
}
if (count($element) != count($element, COUNT_RECURSIVE)) {
$element = array_filter(current($element), __FUNCTION__);
}
return $element;
} else {
return empty($element) ? false : $element;
}
}
$data = array(
'horarios' => array(),
'grupos' => array(
'1A' => array(
'Juan' => array(
'calificaciones' => array(
'Matematicas' => 8,
'Español' => 5,
'Ingles' => 9,
),
'asistencias' => array(
'enero' => 20,
'febrero' => 10,
'marzo' => '',
)
),
'Damian' => array(
'calificaciones' => array(
'Matematicas' => 10,
'Español' => '',
'Ingles' => 9,
),
'asistencias' => array(
'enero' => 20,
'febrero' => '',
'marzo' => 5,
)
),
),
'1B' => array(
'Mariana' => array(
'calificaciones' => array(
'Matematicas' => null,
'Español' => 7,
'Ingles' => 9,
),
'asistencias' => array(
'enero' => null,
'febrero' => 5,
'marzo' => 5,
)
),
),
)
);
$data = array_filter($data, 'removeEmptyElements');
var_dump($data);
¡it works!
A: As per your method, you can just catch those elements in an another array and use that one like follows,
foreach($linksArray as $link){
if(!empty($link)){
$new_arr[] = $link
}
}
print_r($new_arr);
A: I think array_walk is much more suitable here
$linksArray = array('name', ' ', ' 342', '0', 0.0, null, '', false);
array_walk($linksArray, function(&$v, $k) use (&$linksArray){
$v = trim($v);
if ($v == '')
unset($linksArray[$k]);
});
print_r($linksArray);
Output:
Array
(
[0] => name
[2] => 342
[3] => 0
[4] => 0
)
*
*We made sure that empty values are removed even if the user adds more than one space
*We also trimmed empty spaces from the valid values
*Finally, only (null), (Boolean False) and ('') will be considered empty strings
As for False it's ok to remove it, because AFAIK the user can't submit boolean values.
A: As you're dealing with an array of strings, you can simply use array_filter(), which conveniently handles all this for you:
print_r(array_filter($linksArray));
Keep in mind that if no callback is supplied, all entries of array equal to FALSE (see converting to boolean) will be removed. So if you need to preserve elements that are i.e. exact string '0', you will need a custom callback:
// PHP 7.4 and later
print_r(array_filter($linksArray, fn($value) => !is_null($value) && $value !== ''));
// PHP 5.3 and later
print_r(array_filter($linksArray, function($value) { return !is_null($value) && $value !== ''; }));
// PHP < 5.3
print_r(array_filter($linksArray, create_function('$value', 'return $value !== "";')));
Note: If you need to reindex the array after removing the empty elements, use: $linksArray = array_values(array_filter($linksArray));
A: You can use array_filter to remove empty elements:
$emptyRemoved = array_filter($linksArray);
If you have (int) 0 in your array, you may use the following:
$emptyRemoved = remove_empty($linksArray);
function remove_empty($array) {
return array_filter($array, '_remove_empty_internal');
}
function _remove_empty_internal($value) {
return !empty($value) || $value === 0;
}
EDIT: Maybe your elements are not empty per se but contain one or more spaces... You can use the following before using array_filter
$trimmedArray = array_map('trim', $linksArray);
A: The most popular answer on this topic is absolutely INCORRECT.
Consider the following PHP script:
<?php
$arr = array('1', '', '2', '3', '0');
// Incorrect:
print_r(array_filter($arr));
// Correct:
print_r(array_filter($arr, 'strlen'));
Why is this? Because a string containing a single '0' character also evaluates to boolean false, so even though it's not an empty string, it will still get filtered. That would be a bug.
Passing the built-in strlen function as the filtering function will work, because it returns a non-zero integer for a non-empty string, and a zero integer for an empty string. Non-zero integers always evaluate to true when converted to boolean, while zero integers always evaluate to false when converted to boolean.
So, the absolute, definitive, correct answer is:
$arr = array_filter($arr, 'strlen');
A: If you are working with a numerical array and need to re-index the array after removing empty elements, use the array_values function:
array_values(array_filter($array));
Also see: PHP reindex array?
A: The most voted answer is wrong or at least not completely true as the OP is talking about blank strings only. Here's a thorough explanation:
What does empty mean?
First of all, we must agree on what empty means. Do you mean to filter out:
*
*the empty strings only ("")?
*the strictly false values? ($element === false)
*the falsey values? (i.e. 0, 0.0, "", "0", NULL, array()...)
*the equivalent of PHP's empty() function?
How do you filter out the values
To filter out empty strings only:
$filtered = array_diff($originalArray, array(""));
To only filter out strictly false values, you must use a callback function:
$filtered = array_diff($originalArray, 'myCallback');
function myCallback($var) {
return $var === false;
}
The callback is also useful for any combination in which you want to filter out the "falsey" values, except some. (For example, filter every null and false, etc, leaving only 0):
$filtered = array_filter($originalArray, 'myCallback');
function myCallback($var) {
return ($var === 0 || $var === '0');
}
Third and fourth case are (for our purposes at last) equivalent, and for that all you have to use is the default:
$filtered = array_filter($originalArray);
A: $a = array(1, '', '', '', 2, '', 3, 4);
$b = array_values(array_filter($a));
print_r($b)
A: For multidimensional array
$data = array_map('array_filter', $data);
$data = array_filter($data);
A: $linksArray = array_filter($linksArray);
"If no callback is supplied, all entries of input equal to FALSE will be removed." -- http://php.net/manual/en/function.array-filter.php
A: I had to do this in order to keep an array value of (string) 0
$url = array_filter($data, function ($value) {
return (!empty($value) || $value === 0 || $value==='0');
});
A: With these types of things, it's much better to be explicit about what you want and do not want.
It will help the next guy to not get caught by surprise at the behaviour of array_filter() without a callback. For example, I ended up on this question because I forgot if array_filter() removes NULL or not. I wasted time when I could have just used the solution below and had my answer.
Also, the logic is language angnostic in the sense that the code can be copied into another language without having to under stand the behaviour of a php function like array_filter when no callback is passed.
In my solution, it is clear at glance as to what is happening. Remove a conditional to keep something or add a new condition to filter additional values.
Disregard the actual use of array_filter() since I am just passing it a custom callback - you could go ahead and extract that out to its own function if you wanted. I am just using it as sugar for a foreach loop.
<?php
$xs = [0, 1, 2, 3, "0", "", false, null];
$xs = array_filter($xs, function($x) {
if ($x === null) { return false; }
if ($x === false) { return false; }
if ($x === "") { return false; }
if ($x === "0") { return false; }
return true;
});
$xs = array_values($xs); // reindex array
echo "<pre>";
var_export($xs);
Another benefit of this approach is that you can break apart the filtering predicates into an abstract function that filters a single value per array and build up to a composable solution.
See this example and the inline comments for the output.
<?php
/**
* @param string $valueToFilter
*
* @return \Closure A function that expects a 1d array and returns an array
* filtered of values matching $valueToFilter.
*/
function filterValue($valueToFilter)
{
return function($xs) use ($valueToFilter) {
return array_filter($xs, function($x) use ($valueToFilter) {
return $x !== $valueToFilter;
});
};
}
// partially applied functions that each expect a 1d array of values
$filterNull = filterValue(null);
$filterFalse = filterValue(false);
$filterZeroString = filterValue("0");
$filterEmptyString = filterValue("");
$xs = [0, 1, 2, 3, null, false, "0", ""];
$xs = $filterNull($xs); //=> [0, 1, 2, 3, false, "0", ""]
$xs = $filterFalse($xs); //=> [0, 1, 2, 3, "0", ""]
$xs = $filterZeroString($xs); //=> [0, 1, 2, 3, ""]
$xs = $filterEmptyString($xs); //=> [0, 1, 2, 3]
echo "<pre>";
var_export($xs); //=> [0, 1, 2, 3]
Now you can dynamically create a function called filterer() using pipe() that will apply these partially applied functions for you.
<?php
/**
* Supply between 1..n functions each with an arity of 1 (that is, accepts
* one and only one argument). Versions prior to php 5.6 do not have the
* variadic operator `...` and as such require the use of `func_get_args()` to
* obtain the comma-delimited list of expressions provided via the argument
* list on function call.
*
* Example - Call the function `pipe()` like:
*
* pipe ($addOne, $multiplyByTwo);
*
* @return closure
*/
function pipe()
{
$functions = func_get_args(); // an array of callable functions [$addOne, $multiplyByTwo]
return function ($initialAccumulator) use ($functions) { // return a function with an arity of 1
return array_reduce( // chain the supplied `$arg` value through each function in the list of functions
$functions, // an array of functions to reduce over the supplied `$arg` value
function ($accumulator, $currFn) { // the reducer (a reducing function)
return $currFn($accumulator);
},
$initialAccumulator
);
};
}
/**
* @param string $valueToFilter
*
* @return \Closure A function that expects a 1d array and returns an array
* filtered of values matching $valueToFilter.
*/
function filterValue($valueToFilter)
{
return function($xs) use ($valueToFilter) {
return array_filter($xs, function($x) use ($valueToFilter) {
return $x !== $valueToFilter;
});
};
}
$filterer = pipe(
filterValue(null),
filterValue(false),
filterValue("0"),
filterValue("")
);
$xs = [0, 1, 2, 3, null, false, "0", ""];
$xs = $filterer($xs);
echo "<pre>";
var_export($xs); //=> [0, 1, 2, 3]

d18551 | test | The reason you are getting an exception is that under the hood the SocketAsyncEventArgs only uses the buffers present in the list at the time of setting the BufferList property.
Basically you are trying to send en empty buffer with the code :
e.BufferList = new List<ArraySegment<byte>>();
e.BufferList.Add(new ArraySegment<byte>(lTxBytes));
e.BufferList.Add(new ArraySegment<byte>(Encoding.ASCII.GetBytes(lTx.Identity)));
e.BufferList.Add(new ArraySegment<byte>(Encoding.ASCII.GetBytes(lResponse)));
Instead try to do :
var list = new List<ArraySegment<byte>>();
list.Add(new ArraySegment<byte>(lTxBytes));
list.Add(new ArraySegment<byte>(Encoding.ASCII.GetBytes(lTx.Identity)));
list.Add(new ArraySegment<byte>(Encoding.ASCII.GetBytes(lResponse)));
e.BufferList = list;
This behavior is not well documented at all and can only be understood by looking at the BufferList setter code in detail. Behind the scenes the SocketAsyncEventArgs has a WSABuffer array field(for interop with native code) where it copies and pins the byte arrays references when you set the BufferList. Since it is this WSABuffer[] that is sent to native code, that explains why your code throws an exception. | unknown | |

d18557 | test | You are not really providing too much details of the issue. I can give some generic guidelines:
*
*Ensure that there is network connectivity. If you are testing Postman and Mule from the same computer it is probably not an issue.
*Ensure host, port and certificates (if using TLS) are the same. Pointing an HTTPS request to port 80 could cause a timeout sometimes.
*Enable HTTP Wire logging in Mule and compare with Postman code as HTTP to identify any significant difference between the requests. For example: headers, URI, body should be the same, except probably for a few headers. Depends on the API. This is usually the main cause for differences between Postman and Mule, when the request are different. | unknown | |
d18558 | test | It seems like you want a tree whose branching factor is determined on the type level, and can be any natural number. This is fairly straightforward with GADTs:
data Nat = Z | S Nat
data Vec (n :: Nat) a where
Nil :: Vec 'Z a
(:>) :: a -> Vec n a -> Vec ('S n) a
infixr 5 :>
data Tree k a = Leaf | Node a (Vec k (Tree k a))
Vec is the standard way to encode a homogenous length-indexed vector with GADTs (found e.g. here). A node in a tree is then an element of type a and a vector of length k, where each element of the vector is a subtree.
Binary trees are simply
type BinaryTree = Tree ('S ('S 'Z))
and constructing is simply
tree = Node 1 (Node 2 (Leaf :> Leaf :> Nil) :> Leaf :> Nil)
the inferred type will be Num a => Tree ('S ('S 'Z)) a.
But if you really need 10 nodes, writing out ten 'S is still too tedious, so you may want to use type literals:
import qualified GHC.TypeLits as TL
...
type family N (n :: TL.Nat) :: Nat where
N 0 = 'Z
N n = 'S (N (n TL.- 1))
type Tree10 = Tree (N 10)

OK, I think I see what's up now. You are trying to print populations for the various years. Each column is essentially 6 characters wide ("\*\*" set in a setw(3), plus a " "). Trouble is, you only print that column if it's going to get the "**"; otherwise you print nothing. So all the columns with "\*\*" are jammed to the left.
Solution is to always print the column, for each row, whether it gets a "**" or not:
for (int year_counter = 0; year_counter <= count - 1; year_counter++)
if (num <= population[year_counter])
cout << setw(3) << "**" << " ";

A: It sounds like your CheckBox is stretching to the whole width of the grid cell (with all of that width clickable), and you don't want it to stretch.
Set the CheckBox's HorizontalAlignment property to Left (or Center, or Right). Then it will be exactly the width it needs to be for the checkbox, rather than stretching to the entire width provided by its parent. | unknown | |
d18569 | test | As a means of testing if supplied values are within permitted bounds you could try:
$valid_username=in_array( strlen( $username ), range(2,16) );
$valid_password=$password===$repeatPassword && in_array( strlen( $password ), range(8,32) );
if( $valid_username && $valid_password ){/* all good */}
example:
if( $submit ) {
if( $username && $password && $repeatPassword && $email ) {
// hash the Passwords
$password = md5( trim( $password ) );
$repeatPassword = md5( trim( $repeatPassword ) );

/* add to db? */
}
} else echo "<h3 class='text-center'> <span class='alert alert-warning'> Please fill out <b>All</b> fields!</h3> </span>";
}
A: You probably don't need to check the length of both $password and $repeatPassword since you will also be checking to see if they match each other.
if (strlen($password < 8) {
// error
} elseif ($password != $repeatPassword) {
// error
} else {
// ALL IS GOOD !
}
A: I had actually solved my problem, I decided to take out the or to the password and it had solved the problem and everything is up and running.
A: Try this:
if (strlen($password) >= 8 && strlen($password) <= 32) {
if (strlen($repeatpassword) >= 8 && strlen($repeatpassword) <= 32) {
// code here
}
}
I think it's a bit odd to check both passwords, however.
So, my solution would be:
if (strlen($password) >= 8 && strlen($password) <= 32) {
// code here

d18571 | test | In the answer, my extendable component is an h1 as opposed to a p. As it made things easier to debug.
I figured out that the flow works as stated by jelhan in the comments.
*
*There is a createElement (I'm a 100% positive as I saw in the debugger that my h1 custom tag was breaking on __openElement).
*It then parses all the attributes one by one with setAttribute (100% positive, because debugger). Ultimately, the "is" attribute is set by setAttribute. I know that when setAttribute is used, then the web component will not be instantiated.
*It ends with an insertBefore call, at either a flushElement or somewhere else (I saw this in my debugger, didn't bother to pinpoint it).
There is a Stackoverflow question on how a web component should be added in vanillaJS.
With that knowledge, I created a JS fiddle, in which you see the workflow of how Glimmer does it now (workflow-wise), and how Glimmer could be doing it.
I also created a hacky workaround for statically defined elements in a .hbs file (warning: I don't create libraries, I merely poke around in them)
You need to replace __setAttribute with something like this:
__setAttribute(name, value, namespace) {
if(name === "is"){ //hack, hack, hackerdeehack
//I need the actual document, this.dom doesn't cut it. I suppose it's kind of like a shadow DOM, similar to what ReactJS does.
let webComponent = window.document.createElement(this.constructing.tagName, { is: value });
//copy attributes that are already parsed
[...this.constructing.attributes].forEach( attr => { this.dom.setAttribute(webComponent, attr.nodeName, attr.nodeValue, namespace) });
this.constructing = webComponent;
}
this.dom.setAttribute(this.constructing, name, value, namespace);
}
Ultimately, it's up to the EmberJS/Glimmer maintainers to propose a certain way forward. This particular hack was made, because I did not want to mess around with the VM and I also did not want to mess around with the parsing behavior of Glimmer. But I did want to see if I was right in my thinking, and I am (2 days ago, I didn't know that Glimmer existed, so I needed to be a bit thorough).
Some extra info for the curious people
Terminology that I saw:
*
*opcodes: VM thingy, I kind of forgot what it meant in a VM context, but I've seen it in my compiler construction and computer architecture courses. I always translate it as: the table of numbers to which CPUs understand what instruction they should execute.
*System calls: DOM function calls are system calls, as they are what the rendering engine is about.
A couple of handy breakpoints (+ console.log()s) in order to verify the workflow that I outlined:
//element-builder.js
__openElement(tag) {
console.log('NewElementBuilder - __openElement', tag, [this.element], this.element.attributes, 'modules');
debugger;
return this.dom.createElement(tag, this.element);
}
__setAttribute(name, value, namespace) {
debugger;
this.dom.setAttribute(this.constructing, name, value, namespace); //this is how the "is" attribute is set
}
//note: it could also be that __flushElement is called... I didn't check this thoroughly
__appendText(text) {
let { dom, element, nextSibling } = this;
debugger;
console.log('__appendText', dom, element, nextSibling, text);
let node = dom.createTextNode(text);
dom.insertBefore(element, node, nextSibling);
return node;
}
// just to be sure
__flushElement(parent, constructing) {
debugger;
this.dom.insertBefore(parent, constructing, this.nextSibling);

d18572 | test | You have to configure the jobLauncher that you're using to launch jobs to use your TaskExecutor (or a separate pool). The simplest way is to override the bean:
@Bean
JobLauncher jobLauncher(JobRepository jobRepository) {
new SimpleJobLauncher(
taskExecutor: taskExecutor(),
jobRepository: jobRepository)
}
Don't be confused by the warning that will be logged saying that a synchronous task executor will be used. This is due to an extra instance that is created owing to the very awkward way Spring Batch uses to configure the beans it provides in SimpleBatchConfiguration (long story short, if you want to get rid of the warning you'll need to provide a BatchConfigurer bean and specify how 4 other beans are to be created, even if you want to change just one).
Note that it being the same job is irrelevant here. The problem is that by default the job launcher will launch the job on the same thread. | unknown | |
d18573 | test | I assume you have a table view with cells that can be swiped left, and that swiping shows a delete button entitled DELETE.
Then you could do the following:
let firstCell = XCUIApplication().cells.element(boundBy: 0)
firstCell().swipeLeft()
let deleteButton = firstCell.buttons[„DELETE“]
deleteButton.tap()
EDIT:
Thanks for your edit! Your delete button does not have any title text. Thus, you cannot access the button with firstCell.buttons[„DELETE“].
From your screen shot it looks as if the delete button was the only button in the cell. If so, you could try firstCell.buttons.firstMatch.
If you have more buttons, you could access the delete button using firstCell.buttons.element(boundBy: 0) where „0“ had to be replaced by the correct index. | unknown | |

d18575 | test | The problem is that android-support-annotations.jar used to be a separate library containing the android annotations, but for some reason these annotations are already included in recent versions of the android-support-v4.jar file.
Deleting the annotations jar solved the issue.
A: Solved this exact issue in a Cordova project that used the facebook plugin. I was able to successfully build by commenting out this line from platforms\android\project.properties, as shown:
# cordova.system.library.1=com.android.support:support-v4:+
And by commenting out this line from platforms\android\build.gradle, as shown:
// compile "com.android.support:support-v4:+"
Then doing the build. The problem started when I installed (katzer/cordova-plugin-local-notifications) which added these lines, but it created a conflict since the library it was adding to the build was already part of the facebook plugin build.
A: Build->clean Project ,and it worked
A: As other users said, the first elements to troubleshoot are dependencies. Although, sometimes you can struggle for hours and you don't find any problem so you can focus on the build process instead.
Changing the way in which the .dex files are produced sometimes solves the problem. You can go through these steps:
*
*Open your Build.gradle (app) file
*Search for the task dexOptions
*Change it to:
dexOptions {
incremental false
}
If you don't find the task in your file then you can add it.
A: I deleted the android-support-v4.jar and it worked.
A: For me the reason was the new data-binding lib
com.android.databinding:dataBinder:1.0-rc2
it somehow used a conflicting version of the annotations lib, which I could not force with
configurations.all {
resolutionStrategy {
force group: 'com.android.support', name: 'support-v4', version: '23.1.0'
force group: 'com.android.support', name: 'appcompat-v7', version: '23.1.0'
force group: 'com.android.support', name: 'support-annotations', version: '23.1.0'
}
}
but the new rc3 and rc4 versions seem to have fixed it, so just use those versions
A: I had the same problem , but i deleted build files from the build folder
projectname/app/build
and it removed all the related error. "can't clean the project" and also "dex errow with $anim"
A: If this is cordova / ionic project this worked for me
add these line to build.gradle under platforms/android after line number 22 i.e after apply plugin: 'android'
configurations {
all*.exclude group: 'com.android.support', module: 'support-v4'
}
A: I managed to fix this issue. The reason was that I included the android support library 19.0.0 as a dependency, but 19.1.0 is required. See here for more information
So it has to be
dependencies {
compile 'com.android.support:support-v4:19.1.0'
compile 'com.crashlytics.android:crashlytics:1.+'
compile 'com.android.support:support-annotations:20.0.0'
}
A: If you import AppCompat as a library project and you also have android-support-annotations.jar in libs elsewhere, make sure to import everywhere AppCompat library only (it already includes this annotations lib). Then delete all android-support-annotations.jar to avoid merging multiple versions of this library.
A: Updating Android SDK Tools fixed it for me, now it just sees the copy in android-support-v4.jar.
I had the same problem when using ant, and the annotations library was being included automatically by an outdated sdk.dir/tools/ant/build.xml.
A: Clean project works as a temporary fix, but the issue will reappear on next compilation error.
To fix more reliably, I had to update the dependency to android support-v4 to com.android.support:support-v4:22.2.0.
A: Put in your build.gradle the dependency of support-annotations according with your compileSdkVersion. For instance: A project with the compileSdkVersion 25 you can put the following dependence:
compile 'com.android.support:support-annotations:25.0.1'
This will solve your problem.
A: In my case I had a file called cache.xml under /build/intermediates/dex-cache/cache.xml in the root project folder. I deleted this file, rebuild the project and it worked for me.
A: I deleted the android-support-v4.jar and it worked.
Explain - android-support-v4.jar is conflicting with my other .jar files of project\libs files ** specially when you are running with java 8 on AS.
A: Put android-support-v4.jar in your libs folder in eclipse. Clean and build the project. It will resolve the issue.
A: Another reason that messages such as these can come up in Android Studio when building and launching can be the cause of application tags in your libraries.
If you have several Android Library projects that you imported as modules. Go into those projects and remove the <application> ... </application> tags and everything between them. These can cause issues in the build process along with the support library issues already mentioned.
A: From /platforms/android/libs/
delete android-support-v4.jar.
It works for me. | unknown | |
d18576 | test | brian d foy answer is essentially correct. You can pretty much translate this code into Perl6
my $frame = Buf.new;
$frame.append(0xA2);
$frame.append(0x01);
say $frame; # OUTPUT: «Buf:0x<a2 01>»
However, the declaration is not the same:
bu = bytearray( 'þor', encoding='utf8',errors='replace')
in Python would be equivalent to this in Perl 6
my $bú = Buf.new('þor'.encode('utf-8'));
say $bú; # OUTPUT: «Buf:0x<c3 be 6f 72>»
And to use something equivalent to the error transformation, the approach is different due to the way Perl 6 approaches Unicode normalization; you would probably have to use UTF8 Clean 8 encoding.
For most uses, however, I guess Buf, as indicated by brian d foy, is correct.
A: I think you're looking for Buf - a mutable sequence of (usually unsigned) integers. Opening a file with :bin returns a Buf. | unknown | |

d18579 | test | No, you cannot do that without a loop or equivalent construct. (full stop) You can hide the loop inside some functions, such as std::transform(), but not avoid it. Moreover, compilers are well trained to optimize loops (because they are ubiquotous), so there is no good reason to avoid them.
A: Without an explicit loop:
std::transform( std::begin(mykeys), std::end(mykeys),
std::inserter(myMap, myMap.end()),
[] (char c) {return std::make_pair(c, 0);} );
Demo.
A range-based for loop would be far more sexy though, so use that if possible:
for (auto c : mykeys)
myMap.emplace(c, 0);
A: You can not do this without a loop. What you can do is to hide a loop under a standard algorithm because you need to convert an object of type char to an object of type std::map<char, int>::value_type that represents itself std::pair<const char, int>
For example
#include <iostream>
#include <vector>
#include <map>
#include <iterator>
#include <algorithm>
int main()
{
std::vector<char> v { 'a', 'b', 'c' };
std::map<char, int> m;
std::transform( v.begin(), v.end(), std::inserter( m, m.begin() ),
[]( char c ){ return std::pair<const char, int>( c, 0 ); } );
for ( const auto &p : m )
{
std::cout << p.first << '\t' << p.second << std::endl;
}
return 0;
}
The output is
a 0
b 0
c 0
A: Using boost:
template<class Iterators, class Transform>
boost::iterator_range< boost::transform_iterator<
typename std::decay_t<Transform>::type,
Iterator
>> make_transform_range( Iterator begin, Iterator end, Transform&& t ) {
return {
boost::make_transform_iterator( begin, t ),
boost::make_transform_iterator( end, t )
};
}
A helper to map keys to pairs:
template<class T>
struct key_to_element_t {
T val;
template<class K>
std::pair< typename std::decay<K>::type, T > operator()(K&& k) const {
return std::make_pair( std::forward<K>(k), val );
}
};
template<class T>
key_to_element_t< typename std::decay<T>::type > key_to_element( T&& t ) {
return { std::forward<T>(t) };
}
template<class R>
struct range_to_container_t {
R r;
template<class C>
operator C()&& {
using std::begin; using std::end;
return { begin(std::forward<R>(r)), end(std::forward<R>(r)) };
}
};
template<class R>
range_to_container_t<R> range_to_container( R&& r ) { return std::forward<R>(r); }
after all that mess we get:
std::vector<char> mykeys { 'a', 'b', 'c' ];
std::map<char, int> myMap = range_to_container( make_transform_range( begin(mykeys), end(mykeys), key_to_element( 0 ) ) );
which constructs the std::map directly from a transformed sequence of elements in the mykeys vector.
Pretty silly. | unknown | |
d18580 | test | Okay, well first of all, here is a link to a working fiddle: jsfiddle
What you need to do is, to give every element, you want to float a float: left;
I would also give every #frame a position: relative; so that the #title's can position themselves according to their parent element.
As @Antony also pointed out, you made a syntax error with margin-right; 45px;, the first semicolon should be a regular colon!
A: I would first rethink your structure a bit. Here's how I would do it. You can use the link element itself for the thumbnail wrapper - and I would suggest you define the importance of the headings etc with heading tags. Search engines read sites like newspapers. If you don't declare importance, they wont know how to structure your site. I wouldn't use underline tag or italic tag because they are deprecated and I wouldn't use br linebreak because it's unnecessary and it's not really a line break. You can declare that in your .css file.
jsfiddle HERE
The magic is basically the float: left; but this will set you up with a more solid foundation. You see, for example - if you decided that you didn't want italics anymore - you would have to go remove all of those tags from the html. This way you only declare it in one place. Further more, styles that all of the blocks share need not be repeated. All blocks are the same I'm imagining. Mabybe they have different background-images.. but the rest is the same. Think modular.

d18582 | test | In the case of getResultList(), the javadocs state that it returns an java.util.List (see here: http://docs.oracle.com/javaee/5/api/javax/persistence/Query.html#getResultList%28%29 ), that Vector implements.
The result type, aka what's in the list, depends on the criteria projection or, in a JPQL Query, of the from statement.
In your case, because you don't do projection, I think it should return a List<User>.

Now assuming you created a dataset, then you can create an AnnotationSet via curl directly - you will need to use your API key from the console (please don't post your API key publicly here). Below is the command and what you would fill in:
curl -v -X POST -H "Content-Type: application/json" -d '{"datasetId":"YourActualDatasetID", "referenceSetId":"YourActualReferencesetID"}' https://genomics.googleapis.com/v1/annotationsets?fields=asdf&key=YOUR_API_KEY

Thanks,

A: to add to Paul's answer:
annotationSetId must be the id to a real annotation set. We will work on improving the error message.
We would like to require referenceId for all our APIs. We don't for our Variant API because the Reference API didn't exist when we created the Variant API.
To give a user WRITE permission, add the user as a Project Editor. See https://cloud.google.com/iam/docs/quickstart-roles-members#add_a_project_member_and_grant_them_an_iam_role
A: My previous comment didn't get formatted properly, so I'm writing it as an answer instead. For this specific test I would need to enable billing for my account, so my guide is the raw information in the Genomics REST API via the Discovery service:
https://www.googleapis.com/discovery/v1/apis/genomics/v1/rest
Based on the REST API, the scopes for creating a AnnotationSet are the following:
"https://www.googleapis.com/auth/cloud-platform",
"https://www.googleapis.com/auth/genomics"
Since you are getting an authentication error, it would be good to first check on the console (https://console.cloud.google.com) for your project that is tied to your API (server) key that you used, if it is enabled for the Genomics and Cloud APIs?

A: Here is the public references:
https://console.cloud.google.com/storage/browser/genomics-public-data/references/
And here we can get ReferenceIDs:
https://developers.google.com/apis-explorer/#p/genomics/v1/genomics.referencesets.search
A: Glad to hear you got everything to work Amir! It was a fun team effort by the three of us, and I'm always happy to help out as I've used and seen the evolution of the API over the past two years :)
Regarding ReferenceIds I see you already found some of the same links I am posting here. These are basically the id that point to a reference which is a sequence such as a chromosome. A collection of reference IDs belong to a ReferenceSet which represents a reference assembly, and references.bases belong to a ReferenceID. I have not seen in the REST API a way to create load a new reference genome - those are probably populated and made available by Google manually via the backend. Maybe Melissa might have more information regarding that.
Below are a collection of links that may be helpful regarding References - some of which you also discovered - and am listing them as a collection in case others might find them useful in the future:
http://googlegenomics.readthedocs.io/en/latest/use_cases/discover_public_data/reference_genomes.html

https://cloud.google.com/genomics/reference/rest/v1/references
https://cloud.google.com/genomics/reference/rest/v1/references.bases
Each of the above of the REST APIs will have their own specific methods for searching and associating to data.
Hope it helps,

In BS4, when you are searching for attributes with multiple values, you either search for a single value eg:
wear_box = page_content.find_all('p', attrs={'class': 'text-muted'})

}
Thanks to Pete Houston who shares such useful tutorial on basic image processing.
A: It seems you are looking for a waterrippleeffect as this one. Checkout the complete source code. Also check the screenshot how does the effect look like.
A: For others reference, if you want to add the logo of your application (which is in your drawable folder(s)) on top of image use following method:
private Bitmap addWaterMark(Bitmap src) {
int w = src.getWidth();
int h = src.getHeight();
Bitmap result = Bitmap.createBitmap(w, h, src.getConfig());
Canvas canvas = new Canvas(result);
canvas.drawBitmap(src, 0, 0, null);
Bitmap waterMark = BitmapFactory.decodeResource(mContext.getResources(), R.drawable.logo);
canvas.drawBitmap(waterMark, 0, 0, null);
return result;
}
A: If someone is still searching for this, I found a good solution here
It adds a watermark to the bottom right portion and scales it according to the source image which was exactly what I was looking for.
/**
* Embeds an image watermark over a source image to produce
* a watermarked one.
* @param source The source image where watermark should be placed
* @param watermark Watermark image to place
* @param ratio A float value < 1 to give the ratio of watermark's height to image's height,
* try changing this from 0.20 to 0.60 to obtain right results
*/
public static Bitmap addWatermark(Bitmap source, Bitmap watermark, float ratio) {
Canvas canvas;
Paint paint;
Bitmap bmp;
Matrix matrix;
RectF r;
int width, height;
float scale;
width = source.getWidth();
height = source.getHeight();
// Create the new bitmap
bmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
paint = new Paint(Paint.ANTI_ALIAS_FLAG | Paint.DITHER_FLAG | Paint.FILTER_BITMAP_FLAG);
// Copy the original bitmap into the new one
canvas = new Canvas(bmp);
canvas.drawBitmap(source, 0, 0, paint);
// Scale the watermark to be approximately to the ratio given of the source image height
scale = (float) (((float) height * ratio) / (float) watermark.getHeight());
// Create the matrix
matrix = new Matrix();
matrix.postScale(scale, scale);
// Determine the post-scaled size of the watermark
r = new RectF(0, 0, watermark.getWidth(), watermark.getHeight());
matrix.mapRect(r);
// Move the watermark to the bottom right corner
matrix.postTranslate(width - r.width(), height - r.height());
// Draw the watermark
canvas.drawBitmap(watermark, matrix, paint);
return bmp;
}
And it is well commented which is what is a huge plus!
A: In Kotlin:
Note: Its just modified code of above answers
private fun mark(src: Bitmap, watermark: String): Bitmap {
val w = src.width
val h = src.height
val result = Bitmap.createBitmap(w, h, src.config)
val canvas = Canvas(result)
canvas.drawBitmap(src, 0f, 0f, null)
val paint = Paint()
paint.color = Color.RED
paint.textSize = 10f
paint.isAntiAlias = true
paint.isUnderlineText = true
canvas.drawText(watermark, 20f, 25f, paint)
return result
}
val imageBitmap = mark(yourBitmap, "Your Text")
binding.meetProofImageView.setImageBitmap(imageBitmap)
A: You can use androidWM to add a watermark into your image, even with invisible watermarks:
add dependence:
dependencies {
...
implementation 'com.huangyz0918:androidwm:0.2.3'
...
}
and java code:
WatermarkText watermarkText = new WatermarkText(“Hello World”)
.setPositionX(0.5)
.setPositionY(0.5)
.setTextAlpha(100)
.setTextColor(Color.WHITE)
.setTextFont(R.font.champagne)
.setTextShadow(0.1f, 5, 5, Color.BLUE);
WatermarkBuilder.create(this, backgroundBitmap)
.loadWatermarkText(watermarkText)
.getWatermark()
.setToImageView(backgroundView);
You can easily add an image type watermark or a text watermark like this, and the library size is smaller than 30Kb.
A: I tried a few libraries mentioned in other posts, like this, but unfortunately it is missing, and not downloadable now. So I followed AndroidLearner 's answer above, but after tweaking the code a little bit, for those of you who are having trouble rotating the watermark, and what values are valid for the various methods of Paint class, so that the text shows rotated at an angle(like most of the company watermarks do), you can use the below code.
Note that, w and h are the screen width and height respectively, which you can calculate easily, there are tons of ways you can find on stackoverflow only.
public static Bitmap waterMarkBitmap(Bitmap src, String watermark) {
int w = src.getWidth();
int h = src.getHeight();
Bitmap mutableBitmap = Utils.getMutableBitmap(src);
Bitmap result = Bitmap.createBitmap(w, h, mutableBitmap.getConfig());
Canvas canvas = new Canvas(result);
canvas.drawBitmap(src, 0f, 0f, null);
Paint paint = new Paint();
paint.setColor(Color.RED);
paint.setTextSize(92f);
paint.setAntiAlias(true);
paint.setAlpha(70); // accepts value between 0 to 255, 0 means 100% transparent, 255 means 100% opaque.
paint.setUnderlineText(false);
canvas.rotate(45, w / 10f, h / 4f);
canvas.drawText(watermark, w / 10f, h / 4f, paint);
canvas.rotate(-45, w / 10f, h / 4f);
return result;
}
It rotates the text watermark by 45 degrees, and places it at the centre of the bitmap.
Also note that, in case you are not able to get watermark, it might be the case that the bitmap you are using as source is immutable. For this worst case scenario, you can use below method to create a mutable bitmap from an immutable one.
public static Bitmap getMutableBitmap(Bitmap immutableBitmap) {
if (immutableBitmap.isMutable()) {
return immutableBitmap;
}
Bitmap workingBitmap = Bitmap.createBitmap(immutableBitmap);
return workingBitmap.copy(Bitmap.Config.ARGB_8888, true);
}
I found above method inside here. I have tested using both the methods in my application, and it works perfectly after I added above tweaks. Try it and let me know if it works or not.
A: use framelayout. put two imageviews inside the framelayout and specify the position of the watermark imageview. | unknown | |
d18593 | test | options.AcceptAnonymousClients() has no effect on the code flow as client_id is a mandatory parameter in this case (it only affects the token, introspection and revocation endpoints).
options.SignInScheme cannot be set to a scheme belonging to OpenIddict. In most cases, it must correspond to a cookie handler (typically the one registered by Identity).
You will also want to remove /signin-google from the endpoints managed by OpenIddict, as it will prevent the Google authentication handler from working properly. | unknown | |
d18594 | test | You could use content negotiation for that, where your AJAX request sets the Accept header to tell your Express server to return JSON instead of HTML:
router.get('/reports', function(req,res) {
...
if (req.accepts('json')) {
return res.send(theData);
} else {
return res.render('reports', ...);
};
});
Alternatively, you can check if the request was made with an AJAX call using req.xhr (although that's not 100% failsafe).
A: No you can't do both, but you could render the page and send the data at the same time:
res.render('reports',{data:json});
and then access those data in the newly rendered page.
alternatively you could send a flag when making the call , and then decide whether you want to render or send based on this flag.
A: Ideally, it needs to be 2 separate route, one spitting json and other rendering a view. Else, you could pass a url param, depending on which you return json or render a view.
router.get('/reports/json', function(req,res){
var data = JSON_OBJECT;
res.send(data);
});
router.get('/reports', function(req,res){
var data = JSON_OBJECT;
res.render('path-to-view-file', data);
});
A: No, you can't. You can only have a single response to a given request. The browser is either expecting an HTML document or it is expecting JSON, it doesn't make sense to give it both at once.
render just renders a view and then calls send.
You could write your view to output an HTML document with a <script> element containing your JSON in the form of a JavaScript literal. | unknown | |

d18597 | test | If Java had destructors, would I need to call the destructor of an iterator if I destroy the linked list?
To delete an iterator because it corresponds to a deleted node (whatever the list is deleted or not, so all its nodes are deleted or not) is for me the worst possible choice, that means the iterator becomes silently unusable, a very practical way to introduce undefined behaviors at the execution.
In case a node knows its iterators a good way is to mark them invalid when the node is deleted, and in that case to try access the corresponding element of the list or go to the previous/next element produces an exception.
For me the list by itself do not need to know the iterators, and an iterator does not need to know the list by itself, so for question 1 no relation at all between GenericLinkedList<T> and GLLIterator<T>.
For the question 2 no aggregation nor composition, because the iterator just references a node, the iterator has a node is false, an iterator is not composed of nodes nor owns them. In the reverse direction even a node knows the iterators pointing to it that node is not composed of iterator nor owns them, but also just reference them.
If a node knows the iterators you have an association from node to iterator with the multiplicity *, else no relation at all.
In iterator you have a simple association to node, the multiplicity can be 0..1 (0 means the iterator was invalidated) or 1 depending on the implementation.
For the question 3 an interface having no implementation it cannot use something else, contrarily to the implementing class(es). | unknown | |
d18598 | test | Things tend to get very tedious when you handle data attributes in individual arrays. Conceptually, it makes more sense in this scenario to treat a Player as a unique Object to hold their name, number and scores.
public class Player {
private String name;
private int number;
private int scores[];
private int currentGame = 0;
public Player(String name, int number, int numGames) {
this.name = name;
this.number = number;
this.scores = new int[numGames];
}
// Getters and Setters
public String getName() { return name; } // Required
public void addScore(int score) {
if (currentGame < scores.length) {
scores[currentGame++] = score;
}
}
public int getAverage() {
int total = 0;
for (int i = 0; i < currentGame; i++) {
total += scores[i];
}
return total / currentGame;
}
@Override
public String toString() {
return String.format("%s (%s) : avg %d", name, number, getAverage());
}
}
You then can instantiate a player with their name, number and how many games they played. You might, however, like to treat the Player class as a single game and have an Object that describes each Game itself; consisting of 10 Players. The Object is lacking getters/setters for the name and number attribute.
Then you can create a single array to hold all data for a game. If you plan on having multiple games, you may want to have an array of scores instead of a single score per Player.
public static final String[] playerName = {"Jim", "Joe", "Ken", "James", "John", "Bud",
"Clark", "Barry", "Jose", "Paul"};
public static final int[] jerseyNumber = {34, 33, 24, 11, 3, 13, 6, 4, 28, 10};
public Player[] createGame(int numGames) {
Player[] players = new Player[10];
for (int i = 0; i < 10; i++) {
players[i] = new Player(playerName[i], jerseyNumber[i], numGames);
}
return players;
}
Then when you will need to get the score somehow.
public void getScore(Player[] players, int numGames) {
Scanner input = new Scanner(System.in);
for (int i = 0; i < numGames; i++) {
System.out.println("Game " + i);
for (Player player : players) {
