d12301 | train | If you change your setup to
tiles = []
for row in range(0,3):
tiles.append([])
for column in range(0,3):
tiles[-1].append(Tile())
tiles[-1][-1].grid(row, column)
you can access your tiles as tiles[row][column] at the end and get the text to compare against the win conditions. | unknown | |
d12302 | train | You were nearly there: Just use n() instead of sum(Ticket) to count the number of rows:
library(dplyr)
library(lubridate)
data %>%
mutate(Created = dmy(Created)) %>%
group_by(month = floor_date(Created, "month")) %>%
summarize(amount = n())
# A tibble: 2 x 2
month amount
<date> <int>
1 2019-01-01 19
2 2019-02-01 4
However, there is a shortcut which uses count():
data %>%
count(CreatedMonth = dmy(Created) %>% floor_date("month"))
# A tibble: 2 x 2
CreatedMonth n
<date> <int>
1 2019-01-01 19
2 2019-02-01 4
For the sake of completeness, here is also a data.table version:
library(lubridate)
library(data.table)
setDT(data)[, .N, by = .(CreatedMonth = floor_date(dmy(Created), "month"))]
CreatedMonth N

A: Using dplyr we can first convert Created column to actual Date and group them by each month and count number of tickets for each group.
library(dplyr)
df %>%
mutate(Created = as.Date(Created, "%d-%b-%y")) %>%
arrange(Created) %>%
mutate(Yearmon = format(Created, "%B-%Y"),
Yearmon = factor(Yearmon, levels = unique(Yearmon))) %>%
group_by(Yearmon) %>%

d12303 | train | Adding to Jon Skeet's answer, if you want to guarantee that a new thread is created every time, you can write your own TaskScheduler that creates a new thread.
A: Try this:
var taskCompletionSource = new TaskCompletionSource<bool>();
Thread t = new Thread(() =>
{
try
{
Operation();
taskCompletionSource.TrySetResult(true);
}
catch (Exception e)
{
taskCompletionSource.TrySetException(e);
}
});
void Operation()
{
// Some work in thread
}
t.Start();
await taskCompletionSource.Task;
You also can write extension methods for Action, Func and so on.
For example:
public static Task RunInThread(
this Action action,
Action<Thread> initThreadAction = null)
{
TaskCompletionSource<bool> taskCompletionSource = new TaskCompletionSource<bool>();
Thread thread = new Thread(() =>
{
try
{
action();
taskCompletionSource.TrySetResult(true);
}
catch (Exception e)
{
taskCompletionSource.TrySetException(e);
}
});
initThreadAction?.Invoke(thread);
thread.Start();
return taskCompletionSource.Task;
}
or
public static Task<TResult> RunInThread<T1, T2, TResult>(
this Func<T1, T2, TResult> function,
T1 param1,
T2 param2,
Action<Thread> initThreadAction = null)
{
TaskCompletionSource<TResult> taskCompletionSource = new TaskCompletionSource<TResult>();
Thread thread = new Thread(() =>
{
try
{
TResult result = function(param1, param2);
taskCompletionSource.TrySetResult(result);
}
catch (Exception e)
{
taskCompletionSource.TrySetException(e);
}
});
initThreadAction?.Invoke(thread);
thread.Start();
return taskCompletionSource.Task;
}
and use it like that:
var result = await some_function.RunInThread(param1, param2).ConfigureAwait(true);
A: Hello and thank you all for the answers. You all got +1. All suggested solution did not work for my case. The problem is that when you sleep a thread it will be reused at some point of time. The people above suggested:
*
*using LongRunning => This will not work if you have nested/child
tasks
*custom task scheduler => I tried to write my own and also tried this
ThreadPerTaskScheduler which also di not work.
*using pure threads => Still failing...
*you could also check this project at Multithreading.Scheduler github
My solution
I don't like it but it works. Basically I block the thread so it cannot be reused. Bellow are the extension methods and a working example. Again, thank you.

A: If you specify TaskCreationOptions.LongRunning when starting the task, that provides a hint to the scheduler, which the default scheduler takes as an indicator to create a new thread for the task.
It's only a hint - I'm not sure I'd rely on it... but I haven't seen any counterexamples using the default scheduler.
A: Just start threads with new Thread() and then Start() them
static void Main(string[] args)
{
ConcurrentDictionary<int, int> startedThreads = new ConcurrentDictionary<int, int>();
for (int i = 0; i < 10; i++)
{
new Thread(() =>
{
new Thread(() =>
{
startedThreads.AddOrUpdate(Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.ManagedThreadId, (a, b) => b);
}).Start();
for (int j = 0; j < 100; j++)
{
new Thread(() =>
{
while (true)
{
Thread.Sleep(10);
if (startedThreads.ContainsKey(Thread.CurrentThread.ManagedThreadId))
Console.WriteLine("Thread reused");
}
}).Start();
}
}).Start();
}
Console.Read();
}
Tasks are supposed to be managed by the scheduler. The whole idea of Tasks is that the runtime will decide when a new thread is needed. On the other hand if you do need different threads chances are something else in the code is wrong like overdependency on Thread.Sleep() or thread local storage.
As pointed out you can create your own TaskScheduler and use tasks to create threads but then why use Tasks to begin with?
A: Here is a custom TaskScheduler that executes the tasks on a dedicated thread per task:
public class ThreadPerTask_TaskScheduler : TaskScheduler
{
protected override void QueueTask(Task task)
{
var thread = new Thread(() => TryExecuteTask(task));
thread.IsBackground = true;
thread.Start();
}
protected override bool TryExecuteTaskInline(Task task, bool taskWasPreviouslyQueued)
{
return TryExecuteTask(task);
}
protected override IEnumerable<Task> GetScheduledTasks() { yield break; }
}
Usage example:
var parallelOptions = new ParallelOptions()
{
MaxDegreeOfParallelism = 3,
TaskScheduler = new ThreadPerTask_TaskScheduler()
};
Parallel.ForEach(Enumerable.Range(1, 10), parallelOptions, item =>
{
Console.WriteLine($"{DateTime.Now:HH:mm:ss.fff}" +
$" [{Thread.CurrentThread.ManagedThreadId}]" +
$" Processing #{item}" +
(Thread.CurrentThread.IsBackground ? ", Background" : "") +
(Thread.CurrentThread.IsThreadPoolThread ? ", ThreadPool" : ""));
Thread.Sleep(1000); // Simulate CPU-bound work
});
Output:
20:38:56.770 [4] Processing #3, Background
20:38:56.770 [5] Processing #2, Background
20:38:56.770 [1] Processing #1
20:38:57.782 [1] Processing #4
20:38:57.783 [8] Processing #5, Background
20:38:57.783 [7] Processing #6, Background
20:38:58.783 [1] Processing #7
20:38:58.783 [10] Processing #8, Background
20:38:58.787 [9] Processing #9, Background
20:38:59.783 [1] Processing #10
Try it on Fiddle.
This custom TaskScheduler allows the current thread to participate in the computations too. This is demonstrated in the above example by the thread [1] processing the items #1, #4, #7 and #10. If you don't want this to happen, just replace the code inside the TryExecuteTaskInline with return false;.
Another example, featuring the Task.Factory.StartNew method. Starting 100 tasks on 100 different threads:
var oneThreadPerTask = new ThreadPerTask_TaskScheduler();
Task[] tasks = Enumerable.Range(1, 100).Select(_ =>
{
return Task.Factory.StartNew(() =>
{
Thread.Sleep(1000); // Simulate long-running work
}, default, TaskCreationOptions.None, oneThreadPerTask);
}).ToArray();
In this case the current thread is not participating in the work, because all tasks are started behind the scenes by invoking their Start method, and not the

d12306 | train | To clone a repository means that you will download the whole code of the repository to your laptop.
A fork is a copy of a repository. Forking a repository allows you to freely experiment with changes without affecting the original project.
Most commonly, forks are used to either propose changes to someone else's project or to use someone else's project as a starting point for your own idea. More at Fork A Repo.
as @TimBiegeleisen says, you can get the project and stay updated by clone once then git fetch it periodically.
For example, if you want to cloning POX Controller, clone it:
git clone https://github.com/noxrepo/pox
Then to update it, do the following command on your cloned project:
cd pox // go to your clone project
git fetch
Or you can use git pull instead of git fetch if only need to stay update without keeping your change in the cloned project.
But you must remember the difference between git fetch and git pull. @GregHewgill answers explain it in details:
In the simplest terms, git pull does a git fetch followed by a git merge.
You can do a git fetch at any time to update your remote-tracking branches under refs/remotes/<remote>/. This operation never changes any of your own local branches under refs/heads, and is safe to do without changing your working copy. I have even heard of people running git fetch periodically in a cron job in the background (although I wouldn't recommend doing this).
A git pull is what you would do to bring a local branch up-to-date with its remote version, while also updating your other remote-tracking branches.

d12310 | train | Running the command that way works only when connection is done through psql.
A: You can do the following in psql.
SELECT 1 as one, 2 as two \g /tmp/1.csv
then in psql
\! cat /tmp/1.csv
or you can
copy (SELECT 1 as one, 2 as two) to '/tmp/1.csv' with (format csv , delimiter '|');
But You can't STDOUT and filename. Because in manual(https://www.postgresql.org/docs/current/sql-copy.html):
COPY { table_name [ ( column_name [, ...] ) ] | ( query ) }
TO { 'filename' | PROGRAM 'command' | STDOUT }
[ [ WITH ] ( option [, ...] ) ]
the Vertical line | means: you must choose one alternative.(source: https://www.postgresql.org/docs/14/notation.html) | unknown | |
d12311 | train | That looks like protobuf-net; fortunately, the library includes a tool to spit out the .proto schema for what it thinks of your model:
var schema = Serializer.GetProto<TickRecord>();
which comes out as:
message TickRecord {
required bcl.DateTime DT = 1;
required double BidPrice = 2 [default = 0];
required double AskPrice = 3 [default = 0];
required sfixed32 BidSize = 4 [default = 0];
required sfixed32 AskSize = 5 [default = 0];
}
where bcl.DateTime is a protobuf-net complex data type described in "bcl.proto".
Frankly, I suggest changing your date-time to a long using unix time - it'll make things a lot simpler here. That gives you:
message TickRecord {
required sfixed64 DT = 1 [default = 0];
required double BidPrice = 2 [default = 0];
required double AskPrice = 3 [default = 0];
required sfixed32 BidSize = 4 [default = 0];
required sfixed32 AskSize = 5 [default = 0];
}
which you can give to your colleague, and they can run protoc or whatever other platform/library tool they need for protocol buffers in their environment, and they should be set. The serialization format is intentionally cross-platform, so the data should work fine.
Note: *WithLengthPrefix works by wrapping the data in an outer shell. I need to see the exact parameters you are using to advise on how to advise your colleague.
Note: changing the DateTime to long is a breaking change; if you can't do that your colleague will have to look at bcl.proto (just Google it) and translate it into python. | unknown | |

TypeError: %d format: a number is required, not generator
So far, so good: I have the same problem that you've experienced.
The problem is, of course, that what you get when you call a generator function are not values but a generator object...
You have to iterate on the generator objects, using whatever is returned from each iteration, e.g.,
In [13]: print('\n'.join('a:%d, b:%d'%(i,j) for i, j in predict(0,0)))
a:0, b:0
a:1, b:1
a:2, b:4
a:3, b:9
a:4, b:16
a:5, b:25
a:6, b:36
a:7, b:49
a:8, b:64
a:9, b:81
or, if you don't like one-liners,
In [14]: for i, j in predict(0, 0):
...: print('a:%d, b:%d'%(i,j))
...:
a:0, b:0
a:1, b:1
a:2, b:4
a:3, b:9
a:4, b:16
a:5, b:25
a:6, b:36
a:7, b:49
a:8, b:64
a:9, b:81
In other words, you have to explicitly consume what the generator is producing.
A: From the documentation:
Runs inference to determine the class probability predictions.

SOME ARGUMENTS ARE DEPRECATED. They will be removed after 2016-09-15.

d12313 | train | There is one synchronization object in .NET that isn't re-entrant, you are looking for a Semaphore.
Before you commit to this, do get your ducks in a row and ask yourself how it can be possible that BeginProcess() can be called again on the same thread. That is very, very unusual, your code has to be re-entrant for that to happen. This can normally only happen on a thread that has a dispatcher loop, the UI thread of a GUI app is a common example. If this is truly possible and you actually use a Semaphore then you'll get to deal with the consequence as well, your code will deadlock. Since it recursed into BeginProcess and stalls on the semaphore. Thus never completing and never able to call EndProcess(). There's a good reason why Monitor and Mutex are re-entrant :)
A: You can use Semaphore class which came with .NET Framework 2.0.
A good usage of Semaphores is to synchronize limited amount of resources. In your case it seems you have resources like Context which you want to share between consumers.
You can create a semaphore to manage the resources like:
var resourceManager = new Semaphore(0, 10);
And then wait for a resource to be available in the BeginProcess method using:
resourceManager.WaitOne();
And finally free the resource in the EndProcess method using:
resourceManager.Release();
Here's a good blog about using Semaphores in a situation like yours:
https://web.archive.org/web/20121207180440/http://www.dijksterhuis.org/using-semaphores-in-c/
A: There is very simple way to prevent re-entrancy (on one thread):
private bool bRefresh = false;
private void Refresh()
{
if (bRefresh) return;
bRefresh = true;
try
{
// do something here
}
finally
{
bRefresh = false;

d12317 | train | At first I thought that a CASE statement would be appropriate, but then I noticed that your logic always conditionally selects the same two columns a and b. So I think that what you need here is a WHERE clause to handle all the cases.
SELECT a, b
FROM tab
WHERE (x = 'x1' OR
((x = 'x2' OR x = 'x3') AND yy = 123) OR
(x = 'x4' AND yy = 456)) AND
zz = yy
A: You can use dynamic SQL and compose your query from different parts.
For example:
-- common part of query
common_query := 'SELECT a, b FROM tab WHERE zz= yy';
-- set additional condition
IF X=x1 THEN add_where := '';
ELSIF X=x2 OR X=x3 THEN add_where := ' AND yy= 123';
ELSIF X=x4 THEN add_where := ' AND yy= 456';
END IF;
-- compose final query
final_query:= common_query||add_where;
EXECUTE IMMEDIATE final_query;
Of couse when you use dynamic SQL you can use bind variables and you need to remember about return values. | unknown | |

A: You would need some server side processing to be able to do this. This thread has a couple of ways of doing this using PHP, made easier with cPanel to make changes to the mail redirects. If you tell us more about your site and hosting environment, we may be able to give better suggestions.
The server side script would need to then parse your email and perform whatever updates your commands intend. Security is also very important, and it is trivial to forge the 'From' address when sending email. | unknown | |

d12322 | train | You should use regular expression and use function preg_replace() to replace matched string. Here is the full implementation of your special_text() function.
function special_text( $content ) {
$search_for = 'specialtext';
$replace_with = '<span class="special-text"><strong>special</strong>text</span>';
return preg_replace( '/<a.*?>(*SKIP)(*F)|'.$search_for.'/m', $replace_with, $content );
}
In the following regular expression first, using <a.*?> - everything between <a...> is matched and using (*SKIP)(*F)| it is skipped and then from anything else $search_for is matched (in your case it's specialtext).
A: Jezzabeanz quite got it except you can simplify it still with:
return preg_replace("/^def/", $replace_with, $content);
A: If you just want to change the text between the the a tags then a regular expression works wonders.
Here is something I used when I was pulling data from emails sent to me:
(?<=">)(.*?\w)(?=<\/a)
returns "specialtext"
It also returns "specialtext test" if there is whitespace.
Regular expressions are definitely the way to go.
$subject = "abcdef";
$pattern = '/^def/';
preg_match($pattern, $subject, $matches, PREG_OFFSET_CAPTURE, 3);
print_r($matches);
?>

And then do a replace on the returned matches. | unknown | |
d12323 | train | In fact. I have the same behavior. I don't know either it is a bug or a feature. A possible workaround is to use the Folder's toString() function. Something like

Logger.log(folders[i].toString());

int hh_div(int a, int b) {
// TBD: add some checks
return a / b;
}
int hh_add(int a, int b) {
// TBD: add some checks
return a + b;

d12327 | train | Here's what the OpenCL 1.2 spec has to say about setting buffers as kernel arguments:
If the argument is a memory object (buffer, image or image array), the arg_value entry will be a pointer to the appropriate buffer, image or image array object.
So, you need to pass a pointer to the cl_mem objects:
ret=clSetKernelArg(kernel,0,sizeof(cl_mem),(void *) &Abuffer);
A: Why are you using clEnqueueTask? I think you should use clEnqueueNDRangeKernel if you have parallel work to do. Also, just set the global work size; pass NULL for the local work group size. 32x32 is larger than some devices can do. | unknown | |

d12330 | train | I just figured it out.
*
*I renamed the targets to pre-build and post-build without -.
*I went to External Tools Configurations and selected build.xml to the left. On the right, I went to the tab Targets, checked my two targets (in addition to the build target which already had a checkmark) and set the order to be pre-build, build, post-build.
*I went to the project properties and I selected Builders on the left. I created a new builder using the build.xml file and having the three targets from the previous bullet point, in the same order. I placed this builder before the Java builder.
*I removed the post-build target as it puts the version back to 0 and seems to do that earlier than I would like.
I am still not sure that this is the optimal solution. Also, the solution fails when there is no git versioning. I tried using this code for solving the issue but it didn't worked. Nevertheless, it is the best I could do and it helps me getting the info I need in the app.
A: Use Git executable with Argument --version and catch the output in a property for further usage, f.e. :
<project>
<exec executable="git" outputproperty="gitversion">
<arg value="--version"/>
</exec>
<echo>$${gitversion} => ${gitversion}</echo>
</project>
output :
[echo] ${gitversion} => git version 1.8.3.msysgit.0 | unknown | |
d12331 | train | You need to specify an instance of the Food class, so this argument is incorrect:
target:[Food class]
So what you are passing to NSTimer is a Class object, not a Food object.
Instead you probably need an instance variable of the Food instance and specify that:
@interface MyClass ()
{
Food *_food;
}
@implementation MyClass
...
- (void)whatever
{
_food = [Food new]; // This might need to be elsewhere

d12332 | train | First, you can create default DataGenerator to plot original images easily
datagenOrj = keras.preprocessing.image.ImageDataGenerator()
You can flow a small sample like the first five images into your 'datagen'. This generator gets images randomly. To making a proper comparison, small and certain sampling can be good for large dataset.
result_data = datagen.flow(train_data[0:5], train_label[0:5], batch_size=128)
result_data_orj = datagenOrj.flow(train_data[0:5], train_label[0:5], batch_size=128)
When you call the next() function, your data generator loads your first batch. The result should contain both train data and train label. You can access them by index.
def getSamplesFromDataGen(resultData):
x = resultData.next() #fetch the first batch
a = x[0] # train data
b = x[1] # train label
for i in range(0,5):
plt.imshow(a[i])
plt.title(b[i])
plt.show()
Be carefull about plotting. You may need to rescale your data. If your data type is float, you need to scale it between 0 and 1 and if your data type integer, you should scale it between 0 and 255. To do it you can use rescale property.
datagenOrj = keras.preprocessing.image.ImageDataGenerator(rescale=1.0/255.0)
I tried on my own dataset and it is working.

d12335 | train | Clicking on the language button in the lower right corner and selecting typescript react fixed the problem.
A: I faced same problem, even "Typescript React" was selected as the language. I had to click and select the language pack version before getting syntax highlighting working.
A: In my case "JavaScript and TypeScript Nightly" extension was causing the problem.
I had the same problem even when "Typescript React" was selected.
I disabled all the extensions and problem solved.
Then I enabled each extension individually and I've found out "JavaScript and TypeScript Nightly" was causing the problem.
I hope this will help someone.
A: I solved this issue just reloading vscode as required by JavaScript and TypeScript Nightly extension, once it was reload I just double checked that Typescript react was selected and the problem was resolved.
Seems like the real problem was that the library JavaScript and TypeScript Nightly was not fully reloaded. | unknown | |

d12338 | train | Not using an enum, but you can get the same exact thing using a class and a few static members:

public static SATURN = new Planet(5.688e+26, 6.0268e7);
public static URANUS = new Planet(8.686e+25, 2.5559e7);
public static NEPTUNE = new Planet(1.024e+26, 2.4746e7);
private mass: number;
private radius: number;
private constructor(mass: number, radius: number) {

this.radius = radius;

public static G = 6.67300E-11;
public surfaceGravity(): number {
return Planet.G * this.mass / (this.radius * this.radius);
}
public surfaceWeight(otherMass: number) {
return otherMass * this.surfaceGravity();
}
}
console.log(Planet.MERCURY.surfaceGravity());
(code in playground)
In java for each item in the enum a static instance is created, which means that this indeed does the same thing, it's just that java has a nicer syntax for defining enums.
Edit
Here's a version with the equivalent Planet.values() which java will generate:
class Planet {
public static MERCURY = new Planet(3.303e+23, 2.4397e6);
public static VENUS = new Planet(4.869e+24, 6.0518e6);
...
private static VALUES: Planet[] = [];
private mass: number;
private radius: number;
private constructor(mass: number, radius: number) {
this.mass = mass;
this.radius = radius;
Planet.VALUES.push(this);
}
public static values() {
return Planet.VALUES;
}
...
}
2nd edit
Here's a way to implement the valueOf:
public static valueOf(name: string): Planet | null {
const names = Object.keys(this);
for (let i = 0; i < names.length; i++) {
if (this[names[i]] instanceof Planet && name.toLowerCase() === names[i].toLowerCase()) {
return this[names[i]];
}
}
return null;
}
A: Unfortunately it's not possible. You can just assign property names
See this reference for the TypeScript spec https://github.com/microsoft/TypeScript/blob/30cb20434a6b117e007a4959b2a7c16489f86069/doc/spec-ARCHIVED.md#a7-enums
A: You can get the 'same thing' using a const.
Obviously this solution isn't exactly like enumerations, it's just a different use of the keys of a const object instead of an actual enumeration value.
export const OrderStateEnum = {
WAITING_SCORING: { key: 1, value: "WAITING for SCORING" },
WAITING_ACCEPTANCE: { key: 2, value: "Waiting for acceptance" },
ORDER_ACCEPTED: { key: 3, value: "Order accepted" },
} as const
export type OrderStateEnum = keyof typeof OrderStateEnum
export function valueOf(value: string): OrderStateEnum{
for(var key in OrderStateEnum) {
if(value.toLowerCase()=== OrderStateEnum[key].value.toLowerCase()){
return OrderStateEnum[key];
}
}
}
To receive all the values of the false enum:
states = OrderStateEnum;
To receive a certain value of the false enum:
OrderStateEnum.WAITING_SCORING.value;
Below is a usage via *ngFor
<select formControlName="statoOrdine" [(ngModel)]="stato">
<option *ngFor="let item of states | keyvalue" [value]="item.value.key">
{{item.value.value}}</option>
</select> | unknown | |
d12339 | train | The idea of command line arguments is to change the behaviour of your executable file at run time, so you don't need to re-compile your source code if you want slightly different behaviour.

d12341 | train | An easy way is to convert the dates to YYYYMMDD format that can be sorted lexicographically.
Note that MM should be the month represented as a two digit number.
A: You could use the core module Time::Piece to convert the DD-MMM-YY (or any input format) to an ISO 8601 form. This allows simple sorting. This example builds up an array of raw data which includes the ISO value as a sort key; sorts it; and returns the data in sorted order:
#!/usr/bin/env perl
use strict;
use warnings;
use Time::Piece;
my $t;
my @data;
while (<DATA>) {
chomp;
$t = Time::Piece->strptime( $_, "%d %b %y" );
push @data, [ $t->datetime, $_ ]; #...ISO 8601 format...
}
my @sorteddata = sort { $a->[0] cmp $b->[0] } @data;
for my $value (@sorteddata) {
print $value->[1], "\n";
}

A: This can be done using the Time::Piece core module's strptime method to decode the dates and sorting them according to the resulting epoch seconds.
This program demonstrates the idea.
use strict;
use warnings;
use Time::Piece;
my @dates = <DATA>;
chomp @dates;
my @sorted = sort {
Time::Piece->strptime($a, '%d-%b-%y') <=> Time::Piece->strptime($b, '%d-%b-%y')

# map month names to numbers
my %monthnum = (

'MAY' => 5, 'JUN' => 6, 'JUL' => 7, 'AUG' => 8,
'SEP' => 9, 'OCT' => 10, 'NOV' => 11, 'DEC' => 12
);
# sort the array using a helper function
my @sorted_dates = sort { convert_date($a) cmp convert_date($b) } @dates;
print join(", ", @sorted_dates), "\n";
# outputs: 13-JAN-11, 19-FEB-12, 15-APR-12
exit(0);
# THE END
# converts from 19-FEB-12 to 120219, for sorting

}
else
{
die "Unrecognized format: $d1";

d12342 | train | This happens because @position.questions is not an array. It's actually an ActiveRecord::Relation. The problem is that the console actually behaves differently from your server application.
For example, in your console position.questions returns an array. That is because the console is actually evaluating this expression as position.questions.all which is equivalent to position.questions.to_a. In your server application the to_a or all is not called until you actually use the query. This is a good thing because it means you can continue to build up a query and it will only actually get executed when it's called.
For instance:
query = @position.questions
query.first
query.last
Will actually generate two queries that return two records in your server application because the query variable will be assigned an ActiveRecord::Relation instead of an Array. In your console this will generate a single query, but the query will load all of the questions into an Array and assign that to query and then select the first and last elements.
The all, first, last, count and even include? keywords are all triggers that actually execute the query, so in your application when you call @position.questions.include? you are executing a single query on the @position.questions relation. Adding the to_a causes this query to be executed immediately. | unknown | |
d12343 | train | It is much easier to break out the actual value check to a helper function that works on a single element. That way you can easily see where you unpack the Maybe value
isSudokuValues :: (Ix a, Num a) => [Maybe a] -> [Bool]
isSudokuValues =
let
isSudokuValue :: (Ix a, Num a) => Maybe a -> Bool
isSudokuValue Nothing = True
isSudokuValue (Just x) = inRange (1, 9) x
in map isSudokuValue
A: I think you make two errors:
maybe has the following signature:
b -> (a -> b) -> Maybe a -> b
So you should use:
map (maybe True $ inRange (1,9)) list
the fromJust cannot be used, since then maybe would work on a (instead of Maybe a, and furthermore it is one of the tasks of maybe simply to allow safe data processing (such that you don't have to worry about whether the value is Nothing.
Some Haskell users furthermore consider fromJust to be harmfull: there is no guarantee that a value is a Just, so even if you manage to let it work with fromJust, it will error on Nothing, since fromJust cannot handle these. Total programming is one of the things most Haskell programmers aim at.
Demo (with ghci):
Prelude Data.Maybe Data.Ix> (map (maybe True $ inRange (1,9))) [Just 1, Just 15, Just 0, Nothing]
[True,False,False,True]
Prelude Data.Maybe Data.Ix> :t (map (maybe True $ inRange (1,9)))

d12346 | train | As @zx8754 menitioned, you should provide reproducible data.
Without having tested the code (because there's no reproducible data), I would suggest the following, assuming that the data is in the data.frame 'data':
all_products <- unique(data$Product)
colors_use <- rainbow(length(all_products))
plot(y = data[data$Product == all_products[1],"Balance"],
x = data[data$Product == all_products[1],"Origination"],
type = "l",
col = colors_use[1],
ylim = c(min(data$Balance, na.rm = T),max(data$Balance, na.rm = T)),
xlim = c(min(data$Origination, na.rm = T),max(data$Origination, na.rm = T)))
for(i_product in 2:length(all_products)){
lines(y = data[data$Product == all_products[i_product],"Balance"],
x = data[data$Product == all_products[i_product],"Origination"],
col = colors_use[i_product])
}
A: I have not enough reputation to comment, so I write it as an answer. To make @tobiasegli_te's answer shorter, the first plot can be plot(Balance~Origination,data=data,type='n') and then make the subsequent lines done for i_product in 1:length(all_products). That way you need not worry about ylim. Here is an example using the Grunfeld data.
z <- read.csv('http://statmath.wu-wien.ac.at/~zeileis/grunfeld/Grunfeld.csv')
plot(invest~year,data=z,type='n')
for (i in unique(as.numeric(z$firm))) lines(invest~year,data=z,
subset=as.numeric(z$firm)==i, col=i)
Also note that your Origination is not equally spaced. You need to change it to a Date or similar.
A: I guess you want something like the following:
df <- as.data.frame(df[c('Product', 'Balance', 'Origination')])
head(df)
Product Balance Origination

d12349 | train | Answering my own question...
Did you check if you have any thing to open a PDF on your device which has iOS5 on it? Don't forget iBooks is not installed by default and iOS does not think to use Safari as a PDF reader. | unknown | |
d12350 | train | The code you have written seems unrelated to the actual error code. The error code specifically describes this problem:
.../albumart.lua:68: attempt to concatenate global 'album' (a nil value)
This means that you are trying to concatenate the album variable using the concatenate operator .., and it's value happens to be nil.
The code you have written suggests that this should not be the case (even though you may want to try make all the variables in the function local). Please take a look at line 68 in your file to find the problem. | unknown | |
d12351 | train | Using the regex modifier x enables comments in the regex. So the # in your regex is interpreted as a comment character and the rest of the regex is ignored. You'll need to either escape the # or remove the x modifier.
Btw: There's no need to escape the parentheses inside []. | unknown | |
d12352 | train | First of all, make sure your aspects (annotation-based or native syntax) always have a .aj file extension (add them to your project via "New aspect" instead of "New class" menu in whatever IDE you use). I have removed the duplicate class from your repo in my fork and renamed the other one accordingly. I chose the native syntax one, by the way.
What was worse, though, is that you somehow expect unwoven Scala classes in a specific directory, but you did not configure the Scala plugin to actually put them there. I fixed that by adding this snippet:
<configuration>
<outputDir>${project.build.directory}/unwoven-classes</outputDir>
</configuration>
Now the AspectJ Maven plugin finds the Scala classes there and performs binary weaving upon them. This fixes both your Java and Scala test. Both of them failed in Maven before, now at least the Java one works in IntelliJ, but not the Scala one. This is due to the fact that IDEA does not know about this strange Maven setup with the additional (intermediate) directory of yours.
So there is nothing wrong with the aspect as such or AspectJ being unable to work with Scala binaries. The project setup was wrong and in a way it still is with respect to IDE support.
So how can you fix it completely? You have several options:
*
*Put the aspect code into another Maven module and there configure a weave dependency on the Java + Scala module, weaving all classes from there into the aspect module. But then you might still have issues with running the tests. But at least you could configure the IDEA project for post-compile weaving with the right dependency.
*You could also put the Scala code in its own module instead, define it as a dependency for the Java + AspectJ module and apply binary weaving to it that way.
Other variants are possible. I do not want to over-analyse here, I just fixed your Maven setup in a quick and simple approach to get you going:
$ mvn clean verify

P.S.: I have also created a pull request for you to easily integrate my changes into your repo.
P.P.S.: See, an MCVE is more helpful than what you did before: Post a separate question only showing an aspect and then post this question here with only a Maven POM. I needed both plus the other classes in order to reproduce and solve the problem. After you published the GitHub project it was pretty straightforward to find and fix.
A: The problem is likely that aspects are often applied to the semantics of your java code - "find a method with a name like X and do the following around it." But Scala code, when viewed from Java, typically does not follow expected naming conventions. Without more detail on the specific pointcuts being made - and the code on which they're being applied - I couldn't give any more insight. | unknown | |
d12353 | train | Does the view show documents in a response hierarchy? Probably there is an "orphaned" response (Replication conflict or other reason) that is not shown in the view as the parent document is missing, but still is counted in the total- column. Try disable response- hierarchy in the View- Properties and check if there is such a document.
An additional reason for the total not being 0 could also be a document that is protected by a readers- field. Server will add this document to the totals (as View- Index is created by the server) whereas the Designer / User does not see the document.
If you know, what is in the Readers- Field (Role, GroupName, etc.) then make yourself member of that field (by assigning the Role to yourself or add yourself to the group).
If you don't know, what's in there (or something went wrong filling the readers field, e.g. forgot to tick the "multi value"- property), then you need somebody with "Full Access Administration"- right to the server. This Admin- function ovverrides all Reader- fields and makes the document visible to you. | unknown | |
d12354 | train | Parent of the box:
{
overflow-y: auto
}
A: .pull-quote {
background: #fb8063;
width: 300%;
margin: 30px 0 30px -100%;
z-index: 70;
position: relative;
overflow: hidden;
}
this merely clips overflow, and the rest of the content will be invisible
some other things to consider is to resize the whole orange box as well as the tags with it.
other overflow css you can try are: scroll, auto, etc.
quite possibly even set the width of the orange box to be fixed and display it within a div tag that has a background of orange.

*The authentication can be done in each root route component, and then redirect to login page.
*Query parameter also can be used, so the same route can handle multiple ids.
Eg: <Route path={this.props.match.url + '/:id'} exact component={Post} /> and then, in Post component, using const { id } = this.props.match.params to get the id.

d12358 | train | Reset the value of stepper while loading your cell. you can reset the cell property values in cell's prepareForReuse method. add the following method in your ReviewTableViewCell class.
override func prepareForReuse()
{
super.prepareForReuse()
countStepper.value = 0.0
}
A: In tableViewCell VC:
1 - add these field
var cellDelegate: cellProtocol?
var index: IndexPath?
2 - then add this in the delegate:
func onStepperClick(index: Int, sender: UIStepper)
3 - when you have dragged your stepper over as an action use this:
@IBAction func cellStepper(_ sender: UIStepper) {
cellDelegate?.onStepperClick(index: (index?.row)!, sender: sender)
sender.maximumValue = 1 //for incrementing
sender.minimumValue = -1 //for decrementing
//this will make sense later
}
In ViewController
1 - add these to the tableView function that has the cellAtRow variable.
cell.cellDelegate = self
cell.index = indexPath
2 - Use this instead of your stepperButton function
func onStepperClick(index: Int, sender: UIStepper) {
print(index)
if sender.value == 1.0{
//positive side of stepper was pressed
}else if sender.value == -1.0{
//negative side of stepper was pressed
}
sender.value = 0 //resetting to zero so sender.value produce different values on plus and minus

//let layout = cell.goodiesImage
let tag = indexPath.row // +1
cell.tag = tag
photoG.fetchImageWithSize(CGSize(width: 1000, height: 1000), completeBlock: { image, info in

d12361 | train | Your second variant does not work, because you are using the wrong interface (Function expects an input argument) and no syntax to create a function instance, but just an ordinary invocation expression.
You have several choices
*
*Use Supplier. This interface describes a function without parameters and returning a value.
public static <T> T withPaging(Supplier<T> call, int pageSize, int pageNumber) {
try {
PaginationKit.setPaginationInput(pageSize, pageNumber); // Set threadlocal
return call.get();
} finally {
PaginationKit.clearPaginationInput(); // Clear threadlocal
}
}
Instead of insisting on it to return List<T>, we simply allow any return type which raises its versatility. It includes the possibility to return a List of something.
Then, we may use either, a method reference
List<SpecialObject> results=PaginationDecorator.withPaging(
specialService::getSpecialObjs, pageSize, pageNumber);
or a lambda expression:
List<SpecialObject> results=PaginationDecorator.withPaging(
() -> specialService.getSpecialObjs(), pageSize, pageNumber);
*Stay with Function, but allow the caller to pass the required argument
public static <T,R> R withPaging(
Function<T,R> call, T argument, int pageSize, int pageNumber) {
try {
PaginationKit.setPaginationInput(pageSize, pageNumber); // Set threadlocal
return call.apply(argument);
} finally {
PaginationKit.clearPaginationInput(); // Clear threadlocal
}
}
Now, the caller has to provide a function and a value. Since the intended method is an instance method, the receiver instance can be treated like a function argument
Then, the function might be again specified either, as a (now unbound) method reference
List<SpecialObject> results=PaginationDecorator.withPaging(
SpecialService::getSpecialObjs, specialService, pageSize, pageNumber);
or a lambda expression:
List<SpecialObject> results=PaginationDecorator.withPaging(
ss -> ss.getSpecialObjs(), specialService, pageSize, pageNumber);
*There is an alternative to both, resorting to AutoCloseable and try-with-resource, rather than try…finally. Define the helper class as:
interface Paging extends AutoCloseable {
void close();
static Paging withPaging(int pageSize, int pageNumber) {
PaginationKit.setPaginationInput(pageSize, pageNumber);
return ()->PaginationKit.clearPaginationInput();
}
}
and use it like
List<SpecialObject> results;
try(Paging pg=Paging.withPaging(pageSize, pageNumber)) {
results=specialService.getSpecialObjs();
}
The advantage is that this will not break the code flow regarding your intended action, i.e. unlike lambda expressions you may modify all local variables inside the guarded code. Recent IDEs will also warn you if you forget to put the result of withPaging inside a proper try(…) statement. Further, if an exception is thrown and another one occurs inside the cleanup (i.e. clearPaginationInput()), unlike finally, the secondary exception will not mask the primary one but get recorded via addSuppressed instead.
That’s what I would prefer here.
A: Your second approach seems cleaner and easier for this task. As for implementation you can just use Java's Proxy class. It seems easy enough. I don't know any libraries that somehow make it even more easier.
import java.lang.reflect.InvocationHandler;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.lang.reflect.Proxy;
public class PagingDecorator {
public static void setPaginationInput(int pageSize, int pageNumber) {
}
public static void clearPaginationInput() {
}
public static <T> T wrap(final Class<T> interfaceClass, final T object, final int pageSize, final int pageNumber) {
if (object == null) {
throw new IllegalArgumentException("argument shouldn't be null");
}
ClassLoader classLoader = object.getClass().getClassLoader();
return (T) Proxy.newProxyInstance(classLoader, new Class[]{interfaceClass}, new InvocationHandler() {
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
setPaginationInput(pageSize, pageNumber);
try {
return method.invoke(object, args);
} catch (InvocationTargetException e) {
throw e.getTargetException();
} catch (Exception e) {
throw e;
} finally {
clearPaginationInput();
}
}
});
}
public static <T> T wrap(final T object, final int pageSize, final int pageNumber) {
if (object == null) {
throw new IllegalArgumentException("argument shouldn't be null");
}
Class<?>[] iFaces = object.getClass().getInterfaces();
//you can use all interfaces, when creating proxy, but it seems cleaner to only mock the concreate interface that you want..
//unfortunately, you can't just grab T as interface here, becuase of Java's generics' mechanic
if (iFaces.length != 1) {
throw new IllegalArgumentException("Object implements more than 1 interface - use wrap() with explicit interface argument.");
}
Class<T> iFace = (Class<T>) iFaces[0];
return wrap(iFace, object, pageSize, pageNumber);
}
public interface Some {
}
public static void main(String[] args) {
Some s = new Some() {};
Some wrapped1 = wrap(Some.class, s, 20, 20);
Some wrapped2 = wrap(s, 20, 20);
}
}
A: You are using Java 8, right? Maybe you can add a default method without any implementation (sounds a litte weird, I know) like this:
// Your current service interface
interface ServiceInterface <T> {
// Existing method
List<T> getObjects();
// New method with pagination atributes
default List<T> getObjects(int pageSize, int pageNumber) {
throw new UnsupportedOperationException();
}
}
The new services (with pagination suport) must override this method. In my opinion, this way You "keep it simple". | unknown | |
d12362 | train | You could achieve this with what I would call a pythonic one-liner.
We don't need to bother with using a regex, as we can use the built-in .count() method, which will from the documentation:
string.count(s, sub[, start[, end]])
Return the number of (non-overlapping) occurrences of substring sub in string s[start:end]. Defaults for start and end and interpretation of negative values are the same as for slices.
So all we need to do is sum up the occurrences of each keyword in kwlist in the string ltxt. This can be done with a list-comprehension:
output.write(str(sum([ltxt.count(kws) for kws in kwlist])))
Update
As pointed out in @voiDnyx's comment, the above solution writes the sum of all the counts, not for each individual keyword.
If you want the individual keywords outputted, you can just write each one individually from the list:
counts = [ltxt.count(kws) for kws in kwlist]
for cnt in counts:
output.write(str(cnt))
This will work, but if you wanted to get silly and put it all in one-line, you could potentially do:
[output.write(str(ltxt.count(kws))) for kws in kwlist]
Its up to you, hope this helps! :)
If you need to match word boundaries, then yes the only way to do so would be to use the \b in a regex. This doesn't mean that you cant still do it in one line:
[output.write(str(len(re.findall(r'\b'+re.escape(kws)+r'\b'))) for kws in kwlist]
Note how the re.escape is necessary, as the keyword may contain special characters. | unknown | |
d12363 | train | here is my suggestion:
ul {

d12366 | train | Chrome's .apk
Firefox's .apk
Download both .apk files and install to your AVD using adb install apk_name
A: To install something onto a device, you need to already have the device running.
So first, start the device using the emulator command.
Then, in a different terminal/command window, use the adb command to install the package. In my case, I've copied the apk file to the platform-tools folder:
./adb install Firefox_17.0.apk
Like the rest of the emulator, the installation is slow, so be patient.
Of course, this just installs the packages. Getting them to run successfully is another matter entirely. So far, I cannot get the Chrome or Firefox packages to run. Chrome says "Not supported on this version of Android. Version 4.0 is minimal supported version." I am running 4.3 in the emulator. And Firefox starts but then immediately terminates with a "Unfortunately, Firefox has stopped" message.

d12367 | train | What you are doing here is copying the whole screen and draw it at coordinate Rect(442,440,792,520); in your new bitmap... Which is off its canvas.
The coordinate Rect(442,440,792,520) correspond to the part you want to get from the source bitmap. You want to copy it "inside" your new bitmap, so within the rect Rect(0,0,350,80)
You can simply adjust your rect like this :
rect_source := Rect(442,440,792,520);
rect_destination := Rect(0,0,350,80);
The rest of your code seems correct. | unknown | |
d12368 | train | You don't have to use ? as the binding placeholder, you can use :names and an associative array. You can then pass the associative array as the binding list and PDO will now to match the keys of the array with the :binding_names. For example, with an associative array, if the keys match the fields in the database, you can do something like this:
$data = array('one'=>'Cathy', 'two'=>'9 Dark and Twisty Road', 'three'=>'Cardiff');
$fields = array_keys($data);
$field_str = '`'.implode('`,`',$fields).'`';
$bind_vals = ':'.implode(',:',$fields);
$sql = 'INSERT INTO tablename ('.$field_str.') VALUES ('.$bind_vals.')';
$sth = $dbh->prepare($sql);
$sth->execute($data);
That will handle an unknown number of name/value pairs. There is no getting around not knowing what field names to use for the insert. This example would also work with ? as the binding placeholder. So instead of names, you could just repeat the ?:
$bind_vals = str_repeat('?,', count($data));
$sql = 'INSERT INTO tablename ('.$field_str.') VALUES ('.$bind_vals.')';
A: Prepared statements only work with literals, not with identifiers. So you need to construct the SQL statement with the identifiers filled in (and properly escaped).
Properly escaping literals is tricky, though. PDO doesn't provide a method for doing literal-escaping, and MySQL's method of escaping literals (using `) is completely different from every other database and from the ANSI SQL standard. See this question for more detail and for workarounds.
If we simplify the issue of escaping the identifiers, you can use a solution like this:
// assuming mysql semantics
function escape_sql_identifier($ident) {
if (preg_match('/[\x00`\\]/', $ident)) {
throw UnexpectedValueException("SQL identifier cannot have backticks, nulls, or backslashes: {$ident}");
}
return '`'.$ident.'`';
}
// returns a prepared statement and the positional parameter values
function prepareinsert(PDO $pdo, $table, $assoc) {
$params = array_values($assoc);
$literals = array_map('escape_sql_identifier', array_keys($assoc));
$sqltmpl = "INSERT INTO %s (%s) VALUES (%s)";
$sql = sprintf($sqltmpl, escape_sql_identifier($table), implode(',',$literals), implode(',', array_fill(0,count($literals),'?'));
return array($pdo->prepare($sql), $params);
}
function prefixkeys($arr) {
$prefixed = array();
for ($arr as $k=>$v) {
$prefixed[':'.$k] = $v;
}
return $prefixed;
}
// returns a prepared statement with named parameters
// this is less safe because the parameter names (keys) may be vulnerable to sql injection
// In both circumstances make sure you do not trust column names given through user input!
function prepareinsert_named(PDO $pdo, $table, $assoc) {
$params = prefixkeys($assoc);
$literals = array_map('escape_sql_identifier', array_keys($assoc));
$sqltmpl = "INSERT INTO %s (%s) VALUES (%s)";
$sql = sprintf($sqltmpl, escape_sql_identifier($table), implode(',',$literals), implode(', ', array_keys($params)));

myVector = vector<double>(1200, value);
alternative is std::fill, which will avoid memory allocation

IPython.core.display.display_javascript(js, raw=True)
so cells which begin with %%fortran will be syntax-highlighted like FORTRAN. (However, they will still be evaluated as python if you do only this.)
A: For recent IPython version, the selected answer no longer works. The 'config_default' property was renamed options_default (Ipython 6.0.0).
The following works:
import IPython
js = "IPython.CodeCell.options_default.highlight_modes['magic_fortran'] = {'reg':[/^%%fortran/]};"

d12396 | train | This won't work since the Input:checkbox is INSIDE the <label>. Browsers will set focus on the input upon a click on the label.
A: An input element inside an a violates common sense as well as HTML5 CR. Nesting two interactive elements raises the issue which element is activated on mouse click.
Instead of such construct, use valid and sensible HTML markup. Then please formulate the styling question in terms of desired or expected rendering vs. actual rendering, instead of saying that “this” “does not work”. | unknown | |
d12397 | train | One of the solution is to implement an interceptor service where you can format multipart/form-data response.
For example, your inteceptor will be - multipart.interceptor.ts :
@Injectable()
export class MultipartInterceptService implements HttpInterceptor {
private parseResponse(response: HttpResponse<any>): HttpResponse<any> {
const headerValue = response.headers.get('Content-Type');
const body = response.body;
const contentTypeArray = headerValue ? headerValue.split(';') : [];
const contentType = contentTypeArray[0];
switch (contentType) {
case 'multipart/form-data':
if (!body) {
return response.clone({ body: {} });
}
const boundary = body?.split('--')[1].split('\r')[0];
const parsed = this.parseData(body, boundary); // function which parse your data depends on its content (image, svg, pdf, json)
if (parsed === false) {
throw Error('Unable to parse multipart response');
}
return response.clone({ body: parsed });
default:
return response;
}
}
// intercept request and add parse custom response
public intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
return next.handle(customRequest).pipe(
map((response: HttpResponse<any>) => {
if (response instanceof HttpResponse) {
return this.parseResponse(response);
}
})
);
}

d12398 | train | So if I understand correctly, the question is "How do I extract HTML embedded in javascript code".
The quick and dirty solution is to use a regular expression to extract the HTML. This is going to be a little finicky because of quoting but it's not too bad, you need a regular expression which can match a string with escaped quotes, this one will do the trick for doublequotes, it will match anything between doublequotes which is not a double quote, or is a quoted double quote:
"((?:[^"]+|\\")+)"
You can then use that to create a regular expression which will extract the contents of the html string from it's jquery wrapping:
import re
mixed_js_html = r'$(".entry:last").after("<div class=\"entry\"><p>some data</p></div>");')
m = re.search(r'after\("((?:[^"]+|\\")+)"\)', mixed_js_html):
html_code = m.group(1)
html_code = html_code.replace('\\"', '"') # unescape quotes
print(html_code)
# <div class="entry"><p>some data</p></div> | unknown | |
d12399 | train | Container's volumes won't be saved when you commit a container as an image. So you can take advanced of this to exclude a folder (volume) from the snapshot. For example, suppose you want to exclude dir /my-videos from your image when committing. You can run your container mounting /my-videos as a volume:
docker run -i -t -v /my-videos my_container /bin/bash
or you mount a host's folder in container's /my-videos:
docker run -i -t -v /home/user/videos:/my-videos my_container /bin/bash | unknown | |
d12400 | train | nums.size() return a unsigned value,-2 cause overflow.
(int)nums.size()-2 can solve it.
A: The problem is that the size() function returns an unassigned int, and you're comparing it to i, which is a signed int.
Turn this line...
for (int i = 0; i < nums.size() - 2; i++) {
Into this...
for (int i = 0; i < ((int)nums.size()) - 2; i++) {
And here's a link to someone else with a similar problem, if you wanna read more about other solutions...
What is wrong with my For loops? i get warnings: comparison between signed and unsigned integer expressions [-Wsign-compare] | unknown |
