d2704 | train | first do you know what was the default layout for both of your panel's ?
and the shortest work solution is to make the root panel use BorderLayout and when adding the counter call on your root panel object
add(BorderLayout.NORTH,theCounterObject);
and for the button's panel call this on the root panel too
add(BorderLayout.CENTER,theButtonsPanel);
this would solve it in shortened version but it's better to learn not a sip or part but all about layout managers as they are very important for swing , here is start A Visual Guide to Layout Managers.
the pack() method is not necessary but it's a great way to fetch the perfect size it was a good idea from the comment but the problem was about your layout witch was FlowLayout and it's the default for panel but you should do it after changing the layout . | unknown | |
d2705 | train | nextTick simply schedules your function to be invoked on the next tick of the event loop. It does not give that function magical non-blocking properties; JavaScript is still single-threaded. If the function blocks (by performing a lot of CPU-bound work), it will still cause I/O events to queue until the function finishes.
If you need to do CPU-intensive work, do it in a worker process.
A: nextTick is a blocking call (in node v0.10.29 at least, where I tested this), it prevents other events from running. use setImmediate()
A: setImmediate will work better as explained in my blog post setTimeout and Friends as it will allow IO tasks to run before again locking up the main execution thread for a full run of compute. But as the other answers posted suggest, the way to think of this is not "nextTick doesn't work", but perhaps "oops I'm trying to do one of the only things you absolutely must not do in a node.js app and I'm getting the result I was warned about". You can't hog the execution thread in node as it is cooperative multitasking. Break computation into small chunks, use external process helpers, split something off into a supporting C++ library, etc.
A: I'll rewrite your code a little bit. Say we need to process 1000000s of items, and there is a (cpu bound, but ok to call sometimes) function computeItem() and io-bound postItem(). We want to process as much items as possible in the background, but still have responsive event loop. For simplicity, no external workers / queues / services used. Possible solution:
var desiredLatency = 10; // ms
function doBackgroundWork() {
var start = new Date();
var end;
var item;
while (item = computeItem()) {
postItem(item);
if (end - start >= desiredLatency) {
setImmediate(doBackgroundWork); // resume at next event loop invocation after processing other handlers
}
}
}

res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World');

*choose an x at random between -100 and 100
*a circle is defined by x^2 + y^2 = r^2, which in your case equals 100^2 = 10000
*From this equation you can get that y^2 = 10000 - x^2 , therefore the points with a chosen x and y = +/-sqrt(10000 - x^2) will lye on the circle.
*choose an y at random between the two coordinates found at point 3
*You're set!
EDIT:
In JS:
var radius = 100;
x = Math.random() * 2 * radius - radius;
ylim = Math.sqrt(radius * radius - x * x);
y = Math.random() * 2 * ylim - ylim;
Another edit: a jsFiddle Example
A: If you want equidistributed coordinates you better go for
var radius = 100
var center_x = 0
var center_y = 0
// ensure that p(r) ~ r instead of p(r) ~ constant
var r = radius*Math.sqrt(Math.random(1))
var angle = Math.sqrt(2*Math.PI)
// compute desired coordinates
var x = center_x + r*Math.cos(angle);
var y = center_y + r*Math.sin(angle);
If you want more points close to the middle then use
var r = radius*Math.random(1)
instead.
A: not sure what you mean for javascript but
x = R*cos(theta) and y = R*sin(theta) are the Cartesian points for a circle. R is the radius of course and theta is the angle which goes from 0 to 2*Pi.
A: I'm posting this as a solution because this question was the only relevant result in google.
My question/problem was how to add cartesian coordinates inside a circle where x and y would not exceed r.
Examples:
*
*plot: (45,75) inside a circle with a radius of 100 (this would normally fall inside the circle, but not the correct position)
*plot: (100,100) inside a circle with a radius of 100 (this would normally fall outside the circle
Solution
// The scale of the graph to determine position of plot
// I.E. If the graph visually uses 300px but the values only goto 100
var scale = 100;
// The actual px radius of the circle / width of the graph
var radiusGraph = 300;
// Plot the values on a cartesian plane / graph image
var xCart = xVal * radiusGraph;
var yCart = yVal * radiusGraph;
// Get the absolute values for comparison
var xCartAbs = Math.abs( xCart );
var yCartAbs = Math.abs( yCart );
// Get the radius of the cartesian plot
var radiusCart = Math.sqrt( xCart * xCart + yCart * yCart );
// Compare to decide which value is closer to the limit
// Once we know, calculate the largest possible radius with the graphs limit.
// r^2 = x^2 + y^2
if ( xCartAbs > yCartAbs ) { // Less than 45°
diff = scale / xCartAbs;
radiusMaximum = Math.sqrt( radiusGraph * radiusGraph + Math.pow( yCartAbs * diff, 2) );
} else if ( yCartAbs > xCartAbs ) { // Greater than 45°
diff = scale / yCartAbs;
radiusMaximum = Math.sqrt( radiusGraph * radiusGraph + Math.pow( xCartAbs * diff, 2) );
} else { // 45°
radiusMaximum = Math.sqrt( 2 * ( radiusGraph * radiusGraph ) );
}
// Get the percent of the maximum radius that the cartesian plot is at
var radiusDiff = radiusCart / radiusMaximum;
var radiusAdjusted = radiusGraph * radiusDiff;
// Calculate the angle of the cartesian plot
var theta = Math.atan2( yCart, xCart );
// Get the new x,y plot inside the circle using the adjust radius from above
var xCoord = radiusAdjusted * Math.cos( theta );
var yCoord = radiusAdjusted * Math.sin( theta );
A: Not sure if this is correct JavaScript code, but something like this:
for (x = -r; x < r; x++) {
for (y = -r; x < r; y++) {
if ((x * x + y * y) < (r * r)) {
// This x/y coordinate is inside the circle.
// Use <= if you want to count points _on_ the circle, too.
}

d2709 | train | I hear and understand your rant, but this is bordering on being a SuperUser-type question and not a programming question (saved only by the fact you said you would like to implement this yourself).
From the description, it sounds like the Finder bailed when it couldn't copy one particular file (my guess is that it was looking for admin and/or root permission for some priviledged folder).
For massive copies like this, you can use the Terminal command line:
e.g.
cp
or
sudo cp
with options like "-R" (which continues copying even if errors are detected -- unless you're using "legacy" mode) or "-n" (don't copy if the file already exists at the destination). You can see all the possible options by typing in "man cp" at the Terminal command line.
If you really wanted to do this programatically, there are options in NSWorkspace (the performFileoperation:source:destination:files:tag: method (documentation linked for you, look at the NSWorkspaceCopyOperation constant). You can also do more low level stuff via "NSFileManager" and it's copyItemAtPath:toPath:error: method, but that's really getting to brute-force approaches there. | unknown | |
d2710 | train | You have a number of misconceptions here.
Firstly, the password is not hashed because you are not calling any method that hashes it. When you create a user, you must always call create_user, not create; it is the former that hashes the password.
user1 = User.objects.create_user(username='username', email='[email protected]', password='password')
Secondly, the reason user1_s is invalid is clearly explained in the error message: when you want to pass data into a serializer and get a User object out, you need to actually pass a dictionary of data in and not a User object.
So, as a test, this would work:
user1_serialize = UserModelSerializer(user1)
data = user1_serialize.data
user1_deserialize = UserModelSerializer(data=data)
user1_deserialize.is_valid() | unknown | |

d2712 | train | The short answer to your first question is YES.
MongoDB uses ObjectID to generate the unique identifier that is assigned to the _id field.
ObjectID is a 96-bit number
Use ObjectID as a unique identifier at mongodb site
Doing math with this, we could have 2^96 or 7.9228163e+28 unique id.
Secondly, the answer to your second question is YES too!
The scenario that comes here is when you had used all 2^96 unique ids that mongo gave you.
If you going to build a super big application that literary exceeds the limit. You could set the _id on your own. Mongo would notice you whether if _id set is duplicated. | unknown | |

d2715 | train | The documentation has a section on null handling. An empty string is treated the same as null, and you cannot compare nulls (of any type) with equality - as the table in the documentation shows, the result of comparing anything with null is unknown - neither true nor false. You have to use is [not] null to compare anything with null.
In this case you could spell it out explicitly, by seeing is one variable is null and the other isn't, and vice versa, and only compare the actual values if that tells you neither are null:
DECLARE
v_notnull varchar2(30):='this string is never null';
v_input varchar2(30):='';
BEGIN
IF (trim(v_input) is null and trim(v_notnull) is not null)
or (trim(v_input) is not null and trim(v_notnull) is null)
or trim(v_input) != trim(v_notnull) THEN
dbms_output.put_line('the strings do NOT match');
ELSE
dbms_output.put_line('the strings DO match');
END IF;
END;
/
the strings do NOT match
PL/SQL procedure successfully completed.
I've added the missing varchar2 sizes; presumably you based this on a procedure that took arguments without running what you were posting stand-alone...
A: '' is NULL in oracle. So, any comparison with null will always result in false.
Demo:
SQL> DECLARE
2 v_notnull varchar2(1000):='this string is never null';
3 v_input varchar2(1000):='';
4 BEGIN
5 IF v_input is null THEN
6 dbms_output.put_line('v_input is null'); -- should print because v_input is actually null
7 END IF;
8
9 IF trim(v_input) = trim(v_notnull) THEN -- always false because of null
10 dbms_output.put_line('the strings do NOT match');
11 ELSE
12 dbms_output.put_line('the strings DO match'); -- so should print this
13 END IF;
14 END;
15 /
v_input is null -- verified
the strings DO match -- verified
PL/SQL procedure successfully completed.
SQL>
A: Often you only care whether the values match, in which case null values make no difference:
declare
v_notnull varchar2(50) := 'this string is never null';
v_input varchar2(50) := '';
begin
if trim(v_input) = trim(v_notnull) then
dbms_output.put_line('the strings DO match');
else
dbms_output.put_line('the strings do NOT match');
end if;
end;
In some cases you can simplify a comparison of nullable values using a coalesce() or nvl() expression:
if nvl(v_yesno,'N') <> 'Y' then ...
You might be able to use a dummy comparison value (although of course there is a risk that it will match an actual value, depending on the situation):
if nvl(somevalue, chr(0)) <> nvl(othervalue, chr(0)) then ...
By the way, you can distinguish between null and '' by copying the value to a char variable, as a '' will trigger its normally unhelpful blank-padding behaviour. I can't really think of a situation where this would be useful, but just for fun:
declare
v1 varchar2(1) := null;
v2 varchar2(1) := '';
c char(1);
begin
c := v1;
if v1 is null and c is not null then
dbms_output.put_line('v1 = ''''');
elsif c is null then
dbms_output.put_line('v1 is null');
end if;
c := v2;
if v2 is null and c is not null then
dbms_output.put_line('v2 = ''''');
elsif c is null then
dbms_output.put_line('v2 is null');
end if;
end;
Output:
v1 is null
v2 = '' | unknown | |
d2716 | train | This isn't a function, But a way to aggregate all scores at once.
Run through the dictionary and sum the values as you go.
final_dict = {}
for team, scores in qualifier_2.items():
final_dict[team] = 0 # initialize score to 0
for player, score in scores.items():
final_dict[team] += score # accumulate score as you loop
print(final_dict)
Outputs:
{'KKR': 117, 'MI': 117}
A: You call your function with the name of the dictionary
total_runs(qualifier_2,KKR)
Then you try to compare that to a string
if x == 'qualifier_2' and ........ :
Identity comparisons: If you really want/need to ensure that it is the specific dictionary, change it to
if x is qualifier_2 and y == 'KKR':
In a function, you want to use the name of the parameters used in the definition. Inside your function (inside the function's scope) the dictionary you passed as the first argument has been assigned to x and the key you passed as the second argument was assigned to y.
c = sum(x[y].values())
def total_runs(x,y):
if x is qualifier_2 and y == 'KKR':
c = sum(x[y].values())
return c
Your dictionary keys are strings so you need to paa a string for that argument
total_runs(qualifier_2,'KKR')
Functions are used to make a process more generic so that process can be reused with different arguments/values passed to it's parameters. While there may be some reasons to check for specific parameter values (maybe for debugging), usually it defeats the purpose of a function.
You could have written it like this:
def total_runs(x,y):
c = sum(x[y].values())
return c
or
def total_runs(x,y):
return sum(x[y].values())
A: You can use dict.values() to get a list of the numbers, then pass it through sum to get the total:
qualifier_2 = {'KKR' : {'Chris Lynn': 4,
'Sunil Narine': 10,
'Gautam Gambhir (c)': 12,
'Robin Uthappa (wk)': 1,
'Ishank Jaggi': 28,

def total_runs(team):
# If team is not found in the data, return 0.
if team not in qualifier_2:
return 0
# Otherwise, find the team and return a sum of their values.
return sum(qualifier_2[team].values())
print total_runs("KKR") # Output: 117
print total_runs("MI") # Output: 117
You can even simplify it as a one liner, though it might be less readable:
def total_runs(team):
return sum((qualifier_2.get(team) or {}).values())
print total_runs("KKR") # Output: 117
print total_runs("MI") # Output: 117
print total_runs("FOOBAR") # Output: 0 | unknown | |

d2719 | train | There are different options to achieve what you need. You need to start with an identity template that would copy the input XML as is to output.
<xsl:template match="@* | node()">

d2724 | train | The answer is inevitably compiler and target specific, but even if 1ULL is wider than a pointer on whatever target architecture, a good compiler should optimize it away. Which 2's complement integer operations can be used without zeroing high bits in the inputs, if only the low part of the result is wanted? explains why a wider computation truncated to pointer width will give identical results as doing computation with pointer width in the first place. This is why compilers can optimize it away even on 32bit machines (or x86-64 with the x32 ABI) when 1ULL leads to promotion of the + operands to a 64bit type. (Or on some 64bit ABI for some architecture where long long is 128b).
1ULL looks optimal for 64bit, and for 32bit with clang. You don't care about 32bit anyway, but gcc wastes an instruction in the return p[u + 1ULL];. All the other cases are compiled to a single load with scaled-index+4+p addressing mode. So other than one compiler's optimization failure, 1ULL looks fine for 32bit as well. (I think it's unlikely that it's a clang bug and that optimization is illegal).
int v1ULL(std::uint32_t u) { return p[u + 1ULL]; }
// ... load u from the stack
// add eax, 1
// mov eax, DWORD PTR p[0+eax*4]
instead of
mov eax, DWORD PTR p[4+eax*4]
Interestingly, gcc 5.3 doesn't make this mistake when targeting the x32 ABI (long mode with 32bit pointers and a register-call ABI similar to SySV AMD64). It uses a 32bit address-size prefix to avoid using the upper 32b of edi.
Annoyingly, it still uses an address-size prefix when it could save a byte of machine code by using a 64bit effective address (when there's no chance of overflow/carry into the upper32 generating an address outside the low 4GiB). Passing the pointer by reference is a good example:
int x2 (char *&c) { return *c; }
// mov eax, DWORD PTR [edi] ; upper32 of rax is zero
// movsx eax, BYTE PTR [eax] ; could be byte [rax], saving one byte of machine code
Err, actually I forget. 32bit addresses might sign-extend to 64b, not zero-extend. If that's the case, it could have used movsx for the first instruction, too, but that would have cost a byte because movsx has a longer opcode than mov.
Anyway, x32 is still an interesting choice for pointer-heavy code that wants more registers and a nicer ABI, without the cache-miss hit of 8B pointers.
The 64bit asm has to zero the upper32 of the register holding the parameter (with mov edi,edi), but that goes away when inlining. Looking at godbolt output for tiny functions is a valid way to test this.
If we want to make doubly sure that the compiler isn't shooting itself in the foot and zeroing the upper32 when it should know it's already zero, we could make test functions with an arg passed by reference.
int v1ULL(const std::uint32_t &u) { return p[u + 1ULL]; }
// mov eax, DWORD PTR [rdi]
// mov eax, DWORD PTR p[4+rax*4] | unknown | |
d2725 | train | The problem you're having with regards to classloaders is to be expected : if the dependencies of your Eclipse plugins/OSGi bundles are A -> B, with the Clojure jar bootstraped from B, then not being able to see resources of A from B is normal.
There can be no cycles among dependencies of Eclipse plugins, so there can be no cycles among classloader hierarchies.
This is the same problem that you would face if you were to write extensions to B from A with regular Eclipse machinery : plugin B would declare an interface, and an extension point. Then plugin A could implement the interface, and declare an extension to the extension point. This last part allows the Eclipse framework to do some tricks with the bundles: it sees that A declares an extension to B, thus instanciates a class from A implementing the interface declared in B (this works since A depends on B), and gives B the implementation instance from A which is also OK since it implements the interface in B !
(Not sure this is clear).
Anyway, back to plugins written in Clojure.
With Clojure, you don't have, out of the box, such separate environments provided by classloaders, because everything gets aggregated in one "Clojure environment" living in the classloader realm of the plugin embedding the clojure jar.
So one possibility would just be, when plugin A starts, to load the relevant namespaces from A. Then they would be loaded at the right time, and available to any other Clojure code.
Another possibility would be to use the Extension Point/Extension machinery. Eclipse provides a way to use "factories" to create instances of extension points. In Counterclockwise, we leverage this feature, and have a generic factory class (written in java, so no AOT) which takes care of loading the right namespace from the right bundle.
Here are more detail concerning how to extend extension points.
An example from Counterclockwise:
There is an existing Extension Point in the Eclipse framework for contributing hyperlink detectors for the Console contents. Counterclockwise extends this extension point to add nrepl hyperlinks.
In the java world, you would have to directly declare, in your extension, some class of yours which implements interface IPatternMatchListenerDelegate.
But with CCW, for probably the same reasons as you, I try to avoid AOT at all costs, so I can't give a java class name in the extension, or I would have either had to write it in java and compile it, or write a gen-class in Clojure and AOT-compile it.
Instead, CCW leverages a hidden gem of plugin.xml's possibilities: in almost every place, when you have to provide a class name, you can instead provide an instance of IExecutableExtensionFactory whose create() method will be called by the Eclipse framework to create an instance of the desired class.
This allowed me to write a generic class for calling into the Clojure world: I just use, in place of the class name I should have written, the class name ccw.util.GenericExecutableExtension
Extract from plugin.xml :
<extension point="org.eclipse.ui.console.consolePatternMatchListeners">
<consolePatternMatchListener
id="ccw.editors.clojure.nREPLHyperlink"
regex="nrepl://[^':',' ']+:\d+">
<class class="ccw.util.GenericExecutableExtension">
<parameter
name="factory"
value="ccw.editors.clojure.nrepl-hyperlink/factory">
</parameter>
</class>
</consolePatternMatchListener>
Note the class attribute, and how I can give parameters to the factory via the parameter element (the factory has to implement interface IExecutableExtension for being able to be initialized with the parameters).
Finally, you can see that in namespace ccw.editors.clojure.nrepl-hyperlink, the function factory is rather simple and just calls the make function:
(defn make []
(let [state (atom nil)]
(reify org.eclipse.ui.console.IPatternMatchListenerDelegate
(connect [this console] (dosync (reset! state console)))
(disconnect [this] (reset! state nil))
(matchFound [this event] (match-found event @state)))))
(defn factory "plugin.xml hook" [ _ ] (make))
Please note that I'm showing this as an example, and the relevant code in Counterclockwise is not ready to be released as an independant library "ready for consumption".
But you should nonetheless be able to roll your own solution (it's quite easy once you get all the pieces in place in your head).
Hope that helps,

A: Another solution occured to me: it is possible, in Eclipse, despite what I said in my previous answer, to create cyclic dependencies between the classloaders!
Eclipse guys needed to introduce this so that certain types of libraries (log4j, etc.) could work in an OSGi environment (which is what Eclipse is based upon).
This requires to leverage the Eclipse-BuddyPolicy mechanism (Third Party libraries and classloading).
It's quite easy: if you want plugin B to see all classes and resources of plugin A, just add this to plugin B's META-INF/MANIFEST.MF file:
Eclipse-BuddyPolicy: dependent
The line above indicates that plugin B's classloader will be able to access what its dependents classloaders have access to.
I created a sample set of plugins named A and B where B has 2 commands (visible in the top menu) : the first applies a text transformation on the "hello" hard coded string by calling clojure code in B. The second dynamically loads an new text transformation from plugin A, so that when you invoke the first command again, you see the result of applying transformations from B and transformations from A.
In your case, it may not even be required to use Eclipse Extension Point / Extension mechanism at all, after all. It will all depend on how you intent plugin B to "discover" plugin A relevant information.

d2727 | train | When you create a transaction through the GetTransaction method, the DataProvider just creates a new connection and gives you the transaction. You would then need to manually use that transaction to perform whatever action you're going to take against the database. There isn't a way to pass that transaction so that it gets used by, for example, CreatePortal, or any other built-in DNN function. That functionality appears to be just for any additional database access you might make.
In terms of how to wrap a call from the DNN core in a transaction, I don't think you can. The cleanest solution I know to recommend (which, unfortunately, still isn't very clean) is to manually call the stored procedure, using a transaction, rather than going through the controller class.
What's your use case, maybe I can recommend a solution that solves the problem some other way...
A: I was able to use Transactions in DNN with the help of this article.
It doesn't apply to your case, but will help others trying to leverage transactions in DNN. | unknown | |
d2728 | train | You can use jQuery's .ready() event on the document:
$(document).ready(function () {

$(window).load(function () {

d2730 | train | This is not a good idea, in general.
Splitting out your CSS and JavaScript files means that they can be cached independently. You will likely be using a common CSS and JavaScript across many pages. If you don't allow those to be cached, and instead store them in each page, then the user is effectively downloading a new copy of those files for every page they visit.
Now, it is a good idea to served minified versions of these files. Also make sure to add gzip or deflate transfer encoding so that they are compressed. Text compresses nicely... usually around a ratio of 1/8.
(I should note that there has been one occasion where I have loaded everything into a single file. I was working on a single-page web application for the Nintendo Wii, which had no caching capability at all. This is about the only instance where putting everything into a single file made sense. Even then, it is only worth the effort if you automate it server-side.)
A: I don't recommend to concat CSS with JS.
Just put your css at the top of the page and js at the bottom.
To minify your CSS and JS you have to use gruntjs
Also I recommend you to read this article: Front-end performance for web designers and front-end developers
A: If your intention is to load the pages faster:
*
*For images: try to use image sprites or images from different domains because browsers love downloading resources from different domains instead of just one domain.
*For scripts as well as css: use online minifiers that can reduce white-spaces and reduce the size (if you are on a web hosting, your host may be already compressing the scripts for you using gzip etc)
*For landing pages like index pages: If you have less styles then try inserting them inside the <style></style> tag, this will make the page load very fast, Facebook mobile does it that way.
A: If it wasn't a good idea, google wasn't be using it!
If you put everything in single file, you'll get less HTTP requests when the browser will check if the newer version of file is available.
You also get read of the problem that some resources are not refreshed, which is the headache for 'normal' developers, but it's a disaster in AJAX applications.
I don't know of any publicly available tool doing it all, surely Google is having its own. Note also that, for example in GWT, many such embedding was done by compiler.
What you can do is to search for:
CSS image embedder - for encoding images into CSS
CSS and JS minifier - for building single CSS/JS and minimizing it
And you need some simple tool that will embed it into HTML. | unknown | |
d2731 | train | The call to request is asynchronous.
Therefore, calling console.log(stations) in the line immediately after your call to request will print the empty list while your request continues to run in the background.
It prints too quickly - before the stations list has been populated.
Whatever you need to do with stations, you either need to do it in a success callback passed to request, or you need to await the request.
As Dai says above, push is actually mutating the stations array.
I am not sure what implementation of request you are using but it may return a value so you may be able to do something like const response = await request(...) (this could work in conjunction with fixing the error Dai pointed out - one way would be to move the declaration of stations inside the else clause, and then return stations at the end of the else clause).
If you can't await it, you will need to pass a callback that performs the pushes to stations defined as is. | unknown | |

d2735 | train | I think when the problem states "this behavior is undefined" it's just saying that they aren't going to test that condition because you can't reasonably be expected to do anything. It's not actually a task for you to complete - it's just telling you not to worry about those scenarios.
A: Why not write an "ImpossibleStateException" and throw this if the said case is true?
It's part of Java's design that you can write own exception classes, so why not write one and throw it when an undefined state is happening.
I'm not sure how the said state is ever produced, I could imagine if you talk about a kind of board game, maybe somebody fiddles around with the ram or the vm and tries to cheat / hack the game.
Also, if somebody would make a deep test of EVERY possible state of the program, like every variable with every possible value the game allows, there would be around 98% cases that made no sense at all.

Signals that a method has been invoked at an illegal or inappropriate time. In other words, the Java environment or Java application is not in an appropriate state for the requested operation.

d2738 | train | The garbage collector will not remove instances1 from an array list. That is not the problem.
The problem is most likely that you are accessing and updating the array list object without proper synchronization. If you do not synchronize properly, one thread won't always see the changes made by another one.
Declaring the reference to the ArrayList object only guarantees that the threads will see the same list object reference. It makes no guarantees about what happens with the operations on the list object.
1 - Assuming that the array list is reachable when the GC runs, then all elements that have been properly added to the list will also be reachable.

d2748 | train | jOOQ 3.15 requires Java 11 (class file version 55) and you are using Java 8 (class file version 52) in your build. You either need to upgrade to Java 11, downgrade to jOOQ 3.14, or purchase a license for jOOQ 3.15 as all of the commercial editions still support Java 8. | unknown | |
d2749 | train | This is what I would do:
<div id="start">0</div>
<div class="post_content"></div>
$(window).data('ajaxready', true).scroll(function(e) {
var postHeight = $('#post_content').height();
if ($(window).data('ajaxready') == false) return;
var start = parseInt($('#start').text());
var limit = 30; // return 30 posts each
if ($(window).scrollTop() >= postHeight - $(window).height() - 400) {
var height = $(window).scrollTop();
$(window).data('ajaxready', false);
if (start > 0) {
var new_start = start + limit;
var dataString = {articles : start, limit : limit};
$.ajax({
cache: false,
url: 'extendost.php',
type: 'POST',
data: dataString,
success: function(data) {
if ($.trim(data).indexOf('NO POST') > -1) {
/* stop infinite scroll when no more data */
$('#start').text(0);
} else {
$('#post_content').append(data);
$('#start').text(new_start);
}
$(window).data('ajaxready', true);
}
});
}
}
});
This way your #start value will change as it scroll and ready for the next scroll value
Then base on the $start (offset) and $limit, make your query like
$query = "SELECT * FROM articles LIMIT {$limit} OFFSET {$start}";
if (!$result = mysqli_query($con, $query) {
echo 'NO POST';
} else {
// fetch and echo your result;

d2751 | train | The simplest way to do it is this:
sympy.pprint(sympy.sqrt(8))
For me (using rxvt-unicode and ipython) it gives
___

A: In an ipython notebook you can enable Sympy's graphical math typesetting with the init_printing function:
import sympy
sympy.init_printing(use_latex='mathjax')
After that, sympy will intercept the output of each cell and format it using math fonts and symbols. Try:
sympy.sqrt(8)

</div></td></tr>'''
html=soup(html)
print(html.text)
A simple way that prints
Organism
ag Addendum (Bacillus circulans)
Then you can
print(html.text.split('(')[1].split(')')[0])
Which prints Bacillus circulans
A: You could do this using bs4 and regular expressions.
BeautifulSoup Part
from bs4 import BeautifulSoup
h = """
<tr><th class="th10" align="left" valign="top" style="border-color:#000;
border-width: 1px 0px 0px 1px; border-style: solid"><nobr>Organism</nobr>

"""
soup = BeautifulSoup(html_doc, 'html.parser')
Your content lies inside a <div> tag.
tag = soup.find('div')
t = tag.text #'ag\xa0\xa0Addendum (Bacillus circulans)\n'
Regular Expression Part
import re
m = re.match(('(.*)\((.*)\).*', t)
ans = m.group(2) #Bacillus circulans
A: The usual preliminaries.
>>> import bs4
>>> soup = bs4.BeautifulSoup('''\
... <tr><th class="th10" align="left" valign="top" style="border-color:#000; border-width: 1px 0px 0px 1px; border-style: solid"><nobr>Organism</nobr></th><td class="td10" style="border-color:#000; border-width: 1px 1px 0px 1px; border-style: solid"><div style="width:555px;overflow-x:auto;overflow-y:hidden"><a href="/kegg-bin/show_organism?tax=1397">ag</a> Addendum (Bacillus circulans)<br></div></td></tr>''', 'lxml')
Then I prettify the soup to see what I'm up against.
>>> for line in soup.prettify().split('\n'):
... print(line)
...
<html>
<body>
<tr>
<th align="left" class="th10" style="border-color:#000; border-width: 1px 0px 0px 1px; border-style: solid" valign="top">
<nobr>
Organism

</th>
<td class="td10" style="border-color:#000; border-width: 1px 1px 0px 1px; border-style: solid">
<div style="width:555px;overflow-x:auto;overflow-y:hidden">

ag
</a>
Addendum (Bacillus circulans)
<br/>
</div>
</td>
</tr>
</body>
</html>
I can see that the string you want is one of three items that constitute the contents of a div element. My first step is to identify that element, and I use its style attribute.
>>> parentDiv = soup.find('div', attrs={"style":"width:555px;overflow-x:auto;overflow-y:hidden"})
I examine the three items in its contents, and I'm reminded that strings don't have a name; it's None.
>>> for item in parentDiv.contents:
... item, item.name
...
(<a href="/kegg-bin/show_organism?tax=1397">ag</a>, 'a')
('\xa0\xa0Addendum (Bacillus circulans)', None)
(<br/>, 'br')
Then to isolate that string I can use:
>>> BC_string = [_ for _ in parentDiv.contents if not _.name]
>>> BC_string
['\xa0\xa0Addendum (Bacillus circulans)']
Edit: Given information from comment, this is how to handle one page. Find the heading for 'Organism' (in a nobr elment), then look for the div that contains the desired text relative to that element. Filter out the string(s) from other elements that are contents of that div, then use a regex to obtain the parenthesised name of the organism. If the regex fails then offer the whole string.
>>> import bs4
>>> import requests
>>> soup_2 = bs4.BeautifulSoup(requests.get('http://www.kegg.jp/entry/ag:CAA27061').content, 'lxml')
>>> organism = soup_2.find_all('nobr', string='Organism')
>>> parentDiv = organism[0].fetchParents()[0].fetchNextSiblings()[0].find_all('div')[0]
>>> desiredContent = [_.strip() for _ in parentDiv.contents if not _.name and _.strip()]
>>> if desiredContent:
... m = bs4.re.match('[^\(]*\(([^\)]+)', desiredContent[0])
... if m:
... name = m.groups()[0]
... else:
... name = "Couldn't match content of " + desiredContent
...
>>> name
'Bacillus circulans' | unknown | |

d2769 | train | Almost 5 years ago I posted this answer. It contains two pieces of code to pull out an asset from a Framework's bundle. The key piece of code is this:
public func returnFile(_ resource:String, _ fileName:String, _ fileType:String) -> String {
let identifier = "com.companyname.appname" // replace with framework bundle identifier
let fileBundle = Bundle.init(identifier: identifier)
let filePath = (fileBundle?.path(forResource: resource, ofType: "bundle"))! + "/" + fileName + "." + fileType
do {
return try String(contentsOfFile: filePath)
}
catch let error as NSError {
return error.description
}
So what if your framework, which needs to know two things (app bundle and light/dark mode) tweaked this code? Move identifier out to be accessible to the app and not local to this function. Then create either a new variable (I think this is the best way) or a new function to work with the correct set of assets based on light or dark mode.
Now your apps can import your framework, and set things up in it's consumers appropriately. (I haven't tried this, but in theory I think it should work.) | unknown | |

And moving from ASMX to ASHX was not a smart move because they are not for replacing each other.
A: Oddly we moved from ASMX to WCF and then back to ASMX. WCF has quite a few downsides, most of all is cross-platform compatibility issues. If everyone consuming your service is on .NET this isn't an issue, but not all other frameworks have supported the full stack, and frequently they just can't do what WCF produces. We also found that dealing with security and testing was a pain in WCF. If your webservice is marked secure, it has to be secure in WCF, even in your testing environment, which means getting actual SSL certs for each developer. A tremendous pain to be sure.
A: ASMX and WCF are technologies to build web services in .NET. WCF was introduced in .NET 3.0. Its goal is to provide a standard abstraction over all communication technologies and is a recommended way of implementing web services in .NET.
What are the differences between WCF and ASMX web services?
ASHX is a way to write HTTPHandlers in .NET. For more information on what are HTTPHandler
http://forums.asp.net/t/1166701.aspx/1
ASMX services are supported in .NET. However migrating to WCF is recommended. Also, you should write all new services in WCF.
A: Yes, asmx is obsolute with WCF service. you can use asmx when you are working with < 4.0 aspx.
ashx will not be exact replace of asmx.
If you have coding format issue / standard / plenty of code then you can go with MVC Web API 2 (4.0 itself). but compare to WCF you must ensure what will be the recipient's response expectation
("WCF is the evolution of the web service(ASMX) and support various protocols like TCP, HTTP, HTTPS, Named Pipes, MSMQ. but Web api only for HTTP(s)"). | unknown | |
d2782 | train | A1: No. You can't build an image off your host.
You can create an new image according to your requirement like which Operating Sytem (Ubuntu, Fedora), Stack(LAMP, LEMP) and many other things.
Or you can pull an image which will be pre-configured with all the packages like Wordpress Stack image, Magento stack image, Bitnami image which you can pull from docker-hub.
A2: As I have mentioned earlier you can build an image of any operating system you want(Ubuntu, Fedora, Debian) but not off the host.
You just need to pull image from docker-hub. e.g docker pull ubuntu will pull mininmal image of Ubuntu-14.04. And if you need specific version of Ubuntu
like Ubuntu-12.04 version e.g docker pull ubuntu:12.04 will pull minimal image of Ubuntu-12.04
A3: Docker-compose is a tool for defining and running multi-container docker applications. docker-compose conatins a compose file
in which you can configure your application services.
And finally Amazon EC2 Container Registry is little bit different thing. The Idea is the same as docker but Amazon is providing
this as a EC2 Container Service with many other functionality which docker doesn't have right now.
Hope it hepls:-) | unknown | |
d2783 | train | Your uploadFile() method will connect() to the server and then sendall() the file content (in 1024 byte chunks).
Your server, on the other hand, will receive the first 1024 bytes (i.e. the first 1024 bytes of file content), and interpret it according to the protocol, looking at the first three bytes of the file content. The client, however, never sends protocol.HEAD_UPLOAD as the server expects.
(BTW, I would really recommend you PEP8 the code, and refrain from * imports. It makes the code much easier to read, and thus to help.) | unknown | |
d2784 | train | If you think about how to explain the process. There are several methods to solve this including:
*
*You would start with each of the Projects and find out if there does not exist anybody who Works on the project where the Employees name starts with S. You can do this using NOT EXISTS.
or
*Again, start with a Project and find, if any, who Works on the project and their corresponding Employees details using LEFT OUTER JOINs (but starting from the Project) and filtering for employee names starting with S in the JOIN condition. Then GROUP BY the primary key for the project and find those projects HAVING a COUNT of zero matched employees.
Since this appears to be a homework question, I'll leave the rest for you to complete. | unknown | |
d2785 | train | Hello and welcome to Stack Overflow!
Since you are declaring class javatesting1 to be in a package test1, Java expects to find that class in a folder named like the package in order to scan it (using the wildcard).
I have tested your code, importing using wildcard *, with a folder structure like this
folder
*
*javatesting2.java
*test1
*
*javatesting1.java
Try editing your folder structure.
Also please try do adhere to coding conventions: class names should be named using CamelCase, e.g. JavaTesting1 | unknown | |
d2786 | train | This is not a issue related to react-native but related to your response.
You're getting something like '<' in response which cannot be converted to JSON. Try with response.text() | unknown | |
d2787 | train | To combine the best of both worlds, you could create an external styles file, as you would for CSS, but with exported style objects. You could then import it into any file that needs it.
As example, main file:
import React, { Component } from 'react';
import { render } from 'react-dom';
import * as Styles from './svgstyles';
class App extends Component {
render() {
return (
<div>
<svg width="100" height="200" viewBox="0 0 100 200">
<rect x="0" y="0" width="10" height="10" style={Styles.style1} />
<rect x="15" y="0" width="10" height="10" style={Styles.style2} />
<rect x="30" y="0" width="10" height="10" style={Styles.style3} />
<rect x="45" y="0" width="10" height="10" style={Styles.style4} />
<rect x="0" y="15" width="10" height="10" style={Styles.style4} />
<rect x="15" y="15" width="10" height="10" style={Styles.style3} />
<rect x="30" y="15" width="10" height="10" style={Styles.style2} />
<rect x="45" y="15" width="10" height="10" style={Styles.style1} />
</svg>
</div>
);
}
}
render(<App />, document.getElementById('root'));
And an external styles file:
export const style1 = {
stroke: 'red',
strokeWidth: "1",
fill: "blue",
}
export const style2 = {
stroke: 'red',
strokeWidth: "1",
fill: "green",
}
export const style3 = {
stroke: 'red',
strokeWidth: "1",
fill: "yellow",
}
export const style4 = {
...style3,
fill: "pink",
}
Live example here
A: If you just want to DRY up the code, you could create one style-object and reuse it:
const Close = ({
fill, width, height, float,
}) => {
const style = { fill: 'none', stroke: `${fill}`, strokeMiterlimit: 10 }
return (
<svg width={ `${width}px` } height={ `${height}px` } viewBox="0 0 14.48 14.48" style={ { float: `${float}`, cursor: 'pointer' } }>
<title>x</title>
<g id="Layer_2" data-name="Layer 2">
<g id="Background">
<line style={ style } x1="14.13" y1="0.35" x2="0.35" y2="14.13" />
<line style={ style } x1="14.13" y1="14.13" x2="0.35" y2="0.35" />
</g>
</g>
</svg>
);
}
This would also result in a small performance improvement since fewer objects would be created in each render cycle.
A: Actually, if I was in your place, Surely I use fonts instead of SVGs, but for your exact question, I prefer to use constant variables inside of my arrow function, just like below:
import React from 'react';
const Close = ({ fill, width, height, float }) => {
const constStyle = { fill: 'none', stroke: `${fill}`, strokeMiterlimit: 10 };
return (
<svg
width={`${width}px`}
height={`${height}px`}
viewBox="0 0 14.48 14.48"
style={{ float: `${float}`, cursor: 'pointer' }}
>
<title>x</title>
<g id="Layer_2" data-name="Layer 2">
<g id="Background">
<line style={constStyle} x1="14.13" y1="0.35" x2="0.35" y2="14.13" />
<line style={constStyle} x1="14.13" y1="14.13" x2="0.35" y2="0.35" />
</g>
</g>
</svg>
);
};
export default Close;
Even, I make the line dimension variables as props, but I don't know what is your case exactly.

d2789 | train | If the previous line is
$('#dform).validate({
then I guess the problems comes from the fact that validate should be passed options
From the doc ( http://docs.jquery.com/Plugins/Validation/validate ), assuming your code is part of the submitHandler, something like :
$(".selector").validate({
submitHandler: function(form) {
var std_address_copy = $('#dform').find('input[name=del_standard_use_b_as_s]').val();
....
}

d2790 | train | There's already a working, packaged mechanism to handle relocations. It's called dlsym(). While it doesn't directly give you a function pointer, all major C++ compilers support reinterpret_casting the result of dlsym to any ordinary function pointer. (Member functions are another issue altogether, but that's not relevant here) | unknown | |
d2791 | train | Ok, I got it.
I inspected the framework data and noticed this md-selected-value prop, contained in MdTable component. After declaring the prop in my component:
props: [
// ...
'mdSelectedValue'
],
I update its value through a second array, delegated to track what elements are being selected for deletion:
data: () => ({
selezionato = []
})
then I listen for any change in selection:
<md-table v-model="cercato" @md-selected="onSelezionato" md-sort="codice" md-sort-order="asc" md-card md-fixed-header :md-selected-value="selezionato">
In my delete function, after every deletion I reset the the new selezionato value, in order to disable the alternate header:
this.selezionato = []
That's it. | unknown | |
d2792 | train | On modern browsers, you can use querySelectorAll and iterate over the NodeList directly, .remove()ing every iframe:
document.querySelectorAll('iframe')
.forEach(iframe => iframe.remove());
Or, for ES5 compatibility:
Array.prototype.forEach.call(
document.querySelectorAll('iframe'),
function(iframe) {
// can't use .remove: https://developer.mozilla.org/en-US/docs/Web/API/ChildNode/remove
iframe.parentElement.removeChild(iframe);
}
);
A: A loop is the right way. Here's a simple version that will work cross-browser:
function myFunction() {
var elements = document.getElementsByTagName("iframe");
while (elements.length) {
elements[0].parentNode.removeChild(elements[0]);
}
}
That continually removes the last entry in the HTMLCollection. The HTMLCollection is live, so removing an element that's in that collection from the DOM also removes it from the collection, so that will reduce the length until eventually length is zero. | unknown | |
d2793 | train | Just create a new file for each record:

out.newLine();
out.close();
counter++;
} catch (IOException e1) {
System.out.println("Could not write in the file");

}
Just create a counter variable or something to differentiate each file. Append the counter to the file name so it will create a new file for each record... | unknown | |
d2794 | train | You need to use strcmp for string comparison.
Replace
if(name == "yes")
With
if(strcmp(name,"yes") == 0)
strcmp returns
*
*
0 if both strings are identical (equal)
*
Negative value if the ASCII value of first unmatched character is less than second.
*
Positive value if the
ASCII value of first unmatched character is greater than second.
A: == isn't defined for string (or any other array) comparisons - you need to use the standard library function strcmp to compare strings:
if ( strcmp( name, "yes" ) == 0 )
or
if ( !strcmp( name, "yes") )
strcmp is a little non-intuitive in that it returns 0 if the string contents are equal, so the sense of the test will feel wrong. It will return a negative value if the first string is lexicographically less than the second, and a positive value if the first string is lexicographically greater than the second.
You'll need to #include <string.h> in order to use strcmp.
For comparing arrays that aren't strings, use memcmp. | unknown | |
d2795 | train | This is the solution:

d2796 | train | Accessors are only called if you refer to a name on the class.
@strength = 0
This doesn't call an accessor. Ever. Even if one is defined.
self.strength = 0
This will call an accessor. Now, attr_accessor defines strength and strength=. If you're planning to write strength= yourself, then you want attr_reader, which does not define strength= for you.
class Weapon
attr_reader :strength
def initialize()
...
self.strength = 0
end
...
def strength=(value)
...
end
end
A: It might be easier to modify the getter:
class Weapon
attr_accessor :grip, :strength
# ...
def strength
if grip == 'straight'
@strength + 5
else
@strength
end
end
end
w = Weapon.new
w.strength = 10
w.strength
#=> 10
Since the getter always re-calculates the value, you can modify both, strength and grip and it will instantly reflect the change:
w.grip = 'straight'
w.strength
#=> 15
w.strength = 12
w.strength
#=> 17
w.grip = 'curved'
w.strength
#=> 12
To avoid confusion, you could call the initial strength base_strength. | unknown | |
d2797 | train | Is this what you want?
voters <- data.frame(party = c("R", "D", "R", "D", "R", "R", "R", "R", "R", "R", "R", "R", "R", "D", "R"),
vote = c("Y", "N", "Y", "N", "Y", "Y", "Y", "Y", "Y", "Y", "Y", "Y", "Y", "N", "Y"))
ggplot(voters, aes(x = party, fill = vote)) + geom_bar()
You can't tell from this plot (because everyone voted based on party lines) but using the same code, if there were both "Yea" and "Nay" votes coming from the same party, you would get a stacked bar plot showing multiple colors. | unknown | |

d2800 | train | Borland Turbo C++ pre-dates most C++ standards and modern C. I would not expect FMOD or any modern library to work with this compiler.
Visual C++ is free to use in the Express form, and is a vastly better compiler.
A: The code you have listed is FMOD 3 code, yet you are using FMOD 4 headers (and probably libs too). This will not work, I can see from your error pic you have other troubles too, perhaps include paths not being set correctly.
We provide a Borland lib that you will need to link with: 'fmodex_bc.lib' but again this is FMOD 4 code, I would highly recommend looking at the 'playstream' example that ships with the SDK, it demonstrates MP3 playback. | unknown |
