pde is extesion for:
Processing: Java derived language
Wiring: C/C++ derived language (Wiring is derived from Processing)
Early versions of Arduino: C/C++ derived (Arduino IDE is derived from Wiring)
For Arduino for example the IDE preprocessor is adding some #defines and some C/C++ files before giving all to gcc.
A difference not yet mentioned: size limit
void *malloc(size_t size)
can only allocate up to SIZE_MAX
.
void *calloc(size_t nmemb, size_t size);
can allocate up about SIZE_MAX*SIZE_MAX
.
This ability is not often used in many platforms with linear addressing. Such systems limit calloc()
with nmemb * size <= SIZE_MAX
.
Consider a type of 512 bytes called disk_sector
and code wants to use lots of sectors. Here, code can only use up to SIZE_MAX/sizeof disk_sector
sectors.
size_t count = SIZE_MAX/sizeof disk_sector;
disk_sector *p = malloc(count * sizeof *p);
Consider the following which allows an even larger allocation.
size_t count = something_in_the_range(SIZE_MAX/sizeof disk_sector + 1, SIZE_MAX)
disk_sector *p = calloc(count, sizeof *p);
Now if such a system can supply such a large allocation is another matter. Most today will not. Yet it has occurred for many years when SIZE_MAX
was 65535. Given Moore's law, suspect this will be occurring about 2030 with certain memory models with SIZE_MAX == 4294967295
and memory pools in the 100 of GBytes.
If you have access to manipulate the code of the site you are loading, the following should provide a comprehensive method to updating the height of the iframe
container anytime the height of the framed content changes.
Add the following code to the pages you are loading (perhaps in a header). This code sends a message containing the height of the HTML container any time the DOM is updated (if you're lazy loading) or the window is resized (when the user modifies the browser).
window.addEventListener("load", function(){
if(window.self === window.top) return; // if w.self === w.top, we are not in an iframe
send_height_to_parent_function = function(){
var height = document.getElementsByTagName("html")[0].clientHeight;
//console.log("Sending height as " + height + "px");
parent.postMessage({"height" : height }, "*");
}
// send message to parent about height updates
send_height_to_parent_function(); //whenever the page is loaded
window.addEventListener("resize", send_height_to_parent_function); // whenever the page is resized
var observer = new MutationObserver(send_height_to_parent_function); // whenever DOM changes PT1
var config = { attributes: true, childList: true, characterData: true, subtree:true}; // PT2
observer.observe(window.document, config); // PT3
});
Add the following code to the page that the iframe is stored on. This will update the height of the iframe, given that the message came from the page that that iframe loads.
<script>
window.addEventListener("message", function(e){
var this_frame = document.getElementById("healthy_behavior_iframe");
if (this_frame.contentWindow === e.source) {
this_frame.height = e.data.height + "px";
this_frame.style.height = e.data.height + "px";
}
})
</script>
Here's a slightly updated version of Chris Herring's solution, taking into account that you can use innerHTML
as well instead of a creating a new text node:
function insertCss( code ) {
var style = document.createElement('style');
style.type = 'text/css';
if (style.styleSheet) {
// IE
style.styleSheet.cssText = code;
} else {
// Other browsers
style.innerHTML = code;
}
document.getElementsByTagName("head")[0].appendChild( style );
}
CSS
.vr {
border-right: 1px solid #ccc !important;
}
HTML
<div class="row">
<div class="col-md-6 vr">
<p>Column 1</p>
</div>
<div class="col-md-6">
<p>Column 2</p>
</div>
</div
Now, we can use class vr
wherever we need to have a vertical-divider kind of appearance.
Hope it helps!
I added "Microsoft ASP.NET Razor" using Manage NuGet Packages.
With Add References, for some reason, I only had System.Web.Helpers 1.0.0 and 2.0.0... but not 3.0.0.
Another option, that worked form me was to delete the references to System.Web.Mvc and System.Web.Http... then re-add them browing to the package locations in the csproj file (you can most easily edit the project with a text editor):
<Reference Include="System.Web.Http">
<HintPath>..\packages\Microsoft.AspNet.WebApi.Core.5.2.3\lib\net45\System.Web.Http.dll</HintPath>
<Reference Include="System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
<HintPath>..\packages\Microsoft.AspNet.Mvc.5.2.3\lib\net45\System.Web.Mvc.dll</HintPath>
I use this:
public String SEG2HOR( long lnValue) { //OK
String lcStr = "00:00:00";
String lcSign = (lnValue>=0 ? " " : "-");
lnValue = lnValue * (lnValue>=0 ? 1 : -1);
if (lnValue>0) {
long lnHor = (lnValue/3600);
long lnHor1 = (lnValue % 3600);
long lnMin = (lnHor1/60);
long lnSec = (lnHor1 % 60);
lcStr = lcSign + ( lnHor < 10 ? "0": "") + String.valueOf(lnHor) +":"+
( lnMin < 10 ? "0": "") + String.valueOf(lnMin) +":"+
( lnSec < 10 ? "0": "") + String.valueOf(lnSec) ;
}
return lcStr;
}
script is loading before body, keep script after content
Calendar start = Calendar.getInstance();
Calendar end = Calendar.getInstance();
start.set(2010, 7, 23);
end.set(2010, 8, 26);
Date startDate = start.getTime();
Date endDate = end.getTime();
long startTime = startDate.getTime();
long endTime = endDate.getTime();
long diffTime = endTime - startTime;
long diffDays = diffTime / (1000 * 60 * 60 * 24);
DateFormat dateFormat = DateFormat.getDateInstance();
System.out.println("The difference between "+
dateFormat.format(startDate)+" and "+
dateFormat.format(endDate)+" is "+
diffDays+" days.");
This will not work when crossing daylight savings time (or leap seconds) as orange80 pointed out and might as well not give the expected results when using different times of day. Using JodaTime might be easier for correct results, as the only correct way with plain Java before 8 I know is to use Calendar's add and before/after methods to check and adjust the calculation:
start.add(Calendar.DAY_OF_MONTH, (int)diffDays);
while (start.before(end)) {
start.add(Calendar.DAY_OF_MONTH, 1);
diffDays++;
}
while (start.after(end)) {
start.add(Calendar.DAY_OF_MONTH, -1);
diffDays--;
}
One thing that might help others is that you can place: =CDate(Now).ToString("dd/MM/yyyy")
in the Format String Property of SSRS which can be obtained by right clicking the column. That is the cleanest way to do it. Then your expression won't be too large and difficult to visually "parse" :)
I could solve this issue with setting environment variables.
export AWS_ACCESS_KEY=
export AWS_SECRET_ACCESS_KEY=
In IntelliJ + py.test, I set environment variables with [Run] > [Edit Configurations] > [Configuration] > [Environment] > [Environment variables]
Found a similar way to fix this issue (at least it did for me).
First check where the CLI php.ini
is located:
php -i | grep "php.ini"
In my case I ended up with : Configuration File (php.ini) Path => /etc
Then cd ..
all the way back and cd
into /etc
, do ls
in my case php.ini didn't show up, only a php.ini.default
Now, copy the php.ini.default file named as php.ini:
sudo cp php.ini.default php.ini
In order to edit, change the permissions of the file:
sudo chmod ug+w php.ini
sudo chgrp staff php.ini
Open directory and edit the php.ini file:
open .
Tip: If you are not able to edit the php.ini due to some permissions issue then copy 'php.ini.default' and paste it on your desktop and rename it to 'php.ini' then open it and edit it following step 7. Then move (copy+paste) it in /etc folder. Issue will be resolved.
Search for [Date] and make sure the following line is in the correct format:
date.timezone = "Europe/Amsterdam"

Use the traceback module:
import sys
import traceback
try:
assert True
assert 7 == 7
assert 1 == 2
# many more statements like this
except AssertionError:
_, _, tb = sys.exc_info()
traceback.print_tb(tb) # Fixed format
tb_info = traceback.extract_tb(tb)
filename, line, func, text = tb_info[-1]
print('An error occurred on line {} in statement {}'.format(line, text))
exit(1)
if you have Perl on your Solaris, then use it. Otherwise, ls with awk is your next best bet, since you don't have stat or your find is not GNU find.
git rm --cached file
should do what you want.
You can read more details at git help rm
NOTE: I include this answer for completeness since the OP didn't mention what the data source is and we shouldn't make any assumptions.
This query gives the correct answer, but could be slower since it might have to sort all the items in People
, depending on what data structure People
is:
var oldest = People.OrderBy(p => p.DateOfBirth ?? DateTime.MaxValue).First();
UPDATE: Actually I shouldn't call this solution "naive", but the user does need to know what he is querying against. This solution's "slowness" depends on the underlying data. If this is a array or List<T>
, then LINQ to Objects has no choice but to sort the entire collection first before selecting the first item. In this case it will be slower than the other solution suggested. However, if this is a LINQ to SQL table and DateOfBirth
is an indexed column, then SQL Server will use the index instead of sorting all the rows. Other custom IEnumerable<T>
implementations could also make use of indexes (see i4o: Indexed LINQ, or the object database db4o) and make this solution faster than Aggregate()
or MaxBy()
/MinBy()
which need to iterate the whole collection once. In fact, LINQ to Objects could have (in theory) made special cases in OrderBy()
for sorted collections like SortedList<T>
, but it doesn't, as far as I know.
You can add an event listener with 'ended' as first param
Like this :
<video src="video.ogv" id="myVideo">
video not supported
</video>
<script type='text/javascript'>
document.getElementById('myVideo').addEventListener('ended',myHandler,false);
function myHandler(e) {
// What you want to do after the event
}
</script>
The uuid module provides immutable UUID objects (the UUID class) and the functions uuid1(), uuid3(), uuid4(), uuid5() for generating version 1, 3, 4, and 5 UUIDs as specified in RFC 4122.
If all you want is a unique ID, you should probably call uuid1() or uuid4(). Note that uuid1() may compromise privacy since it creates a UUID containing the computer’s network address. uuid4() creates a random UUID.
Docs:
Example (for both Python 2 and 3):
>>> import uuid
>>> uuid.uuid4()
UUID('bd65600d-8669-4903-8a14-af88203add38')
>>> str(uuid.uuid4())
'f50ec0b7-f960-400d-91f0-c42a6d44e3d0'
>>> uuid.uuid4().hex
'9fe2c4e93f654fdbb24c02b15259716c'
Suppose you have a project called "TestProject" on Eclipse and your workspace folder is located at E:/eclipse/workspace. When you build an Eclipse project, your classpath is then e:/eclipse/workspace/TestProject
. When you try to read "staedteliste.txt", you're trying to access the file at e:/eclipse/workspace/TestProject/staedteliste.txt
.
If you want to have a separate folder for your project, then create the Files folder under TestProject and then access the file with (the relative path) /Files/staedteliste.txt
. If you put the file under the src folder, then you have to access it using /src/staedteliste.txt
. A Files folder inside the src folder would be /src/Files/staedteliste.txt
Instead of using the the relative path you can use the absolute one by adding e:/eclipse/workspace/
at the beginning, but using the relative path is better because you can move the project without worrying about refactoring as long as the project folder structure is the same.
This code below is to create map to manager players point. The goal is to concatenate the word "player" with a sequential number.
players_numbers = int(input('How many girls will play? ')) #First - input receive a input about how many people will play
players = {}
counter = 1
for _ in range(players_numbers): #sum one, for the loop reach the correct number
player_dict = {f'player{counter}': 0} #concatenate the word player with the player number. the initial point is 0.
players.update(player_dict) #update the dictionary with every player
counter = counter + 1
print(players)
Output >>> {'player1': 0, 'player2': 0, 'player3': 0}...
The below code will call a function while the script is done loading
<html>

<script>
call();
function call(){ alert("Hello Word");}

actually a much easier way to get a readable array of what you (probably) want to see, is instead of using
dd($users);
or
dd(User::all());
use this
dd($users->toArray());
or
dd(User::all()->toArray());
which is a lot nicer to debug with.
EDIT - additional, this also works nicely in your views / templates so if you pass the get all users to your template, you can then dump it into your blade template
{{ dd($users->toArray()) }}
Here is the solution provided by MySQL: http://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html
Since an array has a fixed size that is allocated when created, your only option is to create a new array without the element you want to remove.
If the element you want to remove is the last array item, this becomes easy to implement using Arrays.copy
:
int a[] = { 1, 2, 3};
a = Arrays.copyOf(a, 2);
After running the above code, a will now point to a new array containing only 1, 2.
Otherwise if the element you want to delete is not the last one, you need to create a new array at size-1 and copy all the items to it except the one you want to delete.
The approach above is not efficient. If you need to manage a mutable list of items in memory, better use a List. Specifically LinkedList
will remove an item from the list in O(1)
(fastest theoretically possible).
Cmdlets in powershell accept a bunch of arguments. When these arguments are defined you can define a position for each of them.
This allows you to call a cmdlet without specifying the parameter name. So for the following cmdlet the path attribute is define with a position of 0 allowing you to skip typing -Path when invoking it and as such both the following will work.
Get-Item -Path C:\temp\thing.txt
Get-Item C:\temp\thing.txt
However if you specify more arguments than there are positional parameters defined then you will get the error.
Get-Item C:\temp\thing.txt "*"
As this cmdlet does not know how to accept the second positional parameter you get the error. You can fix this by telling it what the parameter is meant to be.
Get-Item C:\temp\thing.txt -Filter "*"
I assume you are getting the error on the following line of code as it seems to be the only place you are not specifying the parameter names correctly, and maybe it is treating the = as a parameter and $username as another parameter.
Set-ADUser $user -userPrincipalName = $newname
Try specifying the parameter name for $user and removing the =
Definitely late to the party; anyway, for those interested, picking up on Lan's mention of HTML5 canvas, you can use gRaphaël Charting which has a MIT License (instead of HighCharts dual license). It's not Bootstrap-specific either, so it's more of a general suggestion.
I have to admit that HighCharts demos seem very pretty, and I have to warn that gRaphaël is quite hard to understand before becoming proficient with it. Anyway you can easily add nice features to your gRaphaël charts (say, tooltips or zooming effects), so it may be worth the effort.
No way to do this that I know of, although I'm very curious to read if anyone has a good answer. I have been thinking about adding something like this to one of the apps my company builds, but have found no good way to do it.
The one thing I can think of (although not directly on point) is that I believe you can limit the total memory usage for a COM+ application in Windows. It would require the app to be written to run in COM+, of course, but it's the closest way I know of.
The working set stuff is good (Job Objects also control working sets), but that's not total memory usage, only real memory usage (paged in) at any one time. It may work for what you want, but afaik it doesn't limit total allocated memory.
For those of you, who doesn't like this monstrous new AClass[] { ... }
syntax, here's some sugar:
public AClass[] c(AClass... arr) { return arr; }
Use this little function as you like:
AClass[] array;
...
array = c(object1, object2);
I am using the following to conditionally set the class attr when ng-class can't be used (for example when styling SVG):
ng-attr-class="{{someBoolean && 'class-when-true' || 'class-when-false' }}"
The same approach should work for other attribute types.
(I think you need to be on latest unstable Angular to use ng-attr-, I'm currently on 1.1.4)
I have published an article on working with AngularJS+SVG that talks about this and related issues. http://www.codeproject.com/Articles/709340/Implementing-a-Flowchart-with-SVG-and-AngularJS
Use the collapse
argument to paste
:
paste(a,collapse=" ")
[1] "aa bb cc"
Double backslash also works ! Then you declare there really should be a / instead of some function or something.

I think I have a more elegant way with event delegation and event capturing on window
's error
even when the backup image fail to load.
img {_x000D_
width: 100px;_x000D_
height: 100px;_x000D_
}
_x000D_
<script>_x000D_
window.addEventListener('error', windowErrorCb, {_x000D_
capture: true_x000D_
}, true)_x000D_
_x000D_
function windowErrorCb(event) {_x000D_
let target = event.target_x000D_
let isImg = target.tagName.toLowerCase() === 'img'_x000D_
if (isImg) {_x000D_
imgErrorCb()_x000D_
return_x000D_
}_x000D_
_x000D_
function imgErrorCb() {_x000D_
let isImgErrorHandled = target.hasAttribute('data-src-error')_x000D_
if (!isImgErrorHandled) {_x000D_
target.setAttribute('data-src-error', 'handled')_x000D_
target.src = 'backup.png'_x000D_
} else {_x000D_
//anything you want to do_x000D_
console.log(target.alt, 'both origin and backup image fail to load!');_x000D_
}_x000D_
}_x000D_
}_x000D_
</script>_x000D_
<img id="img" src="error1.png" alt="error1">_x000D_

<img id="img" src="https://i.stack.imgur.com/ZXCE2.jpg" alt="avatar">
_x000D_
The point is :
Put the code in the head
and executed as the first inline script. So, it will listen the errors happen after the script.
Use event capturing to catch the errors, especially for those events which don't bubble.
Use event delegation which avoids binding events on each image.
Give the error img
element an attribute after giving them a backup.png
to avoid disappearance of the backup.png
and subsequent infinite loop like below:
img error->backup.png->error->backup.png->error->,,,,,
Mathcha is a sophisticated mathematics editor, but it can be used to render individual equations and save them as pure html, which you can then add to your documents as inline html OR you can save as SVG and insert as an image. https://www.mathcha.io/
in fact there is a subtelty with the c()
function. If you do:
x <- list()
x <- c(x,2)
x = c(x,"foo")
you will obtain as expected:
[[1]]
[1]
[[2]]
[1] "foo"
but if you add a matrix with x <- c(x, matrix(5,2,2)
, your list will have another 4 elements of value 5
!
You would better do:
x <- c(x, list(matrix(5,2,2))
It works for any other object and you will obtain as expected:
[[1]]
[1]
[[2]]
[1] "foo"
[[3]]
[,1] [,2]
[1,] 5 5
[2,] 5 5
Finally, your function becomes:
push <- function(l, ...) c(l, list(...))
and it works for any type of object. You can be smarter and do:
push_back <- function(l, ...) c(l, list(...))
push_front <- function(l, ...) c(list(...), l)
You can get the projection from the MapView object which is passed into the draw() method: mapv.getProjection().toPixels(gP1, p1);

For my case, it was /Users/.../Library/Python/2.7/bin

file):
export PATH=$PATH:/Users/.../Library/Python/2.7/bin
var_dump($obj);
If you want more info you can use a ReflectionClass:
Almost there. In your predicate, you want a relative path, so change
./book[/author/name = 'John']
to either
./book[author/name = 'John']
or
./book[./author/name = 'John']
and you will match your element. Your current predicate goes back to the root of the document to look for an author
.
I do not want to craft special error handlers for every loop structure in my code so I have a way of finding problem loops using my standard error handler so that I can then write a special error handler for them.
If an error occurs in a loop, I normally want to know about what caused the error rather than just skip over it. To find out about these errors, I write error messages to a log file as many people do. However writing to a log file is dangerous if an error occurs in a loop as the error can be triggered for every time the loop iterates and in my case 80 000 iterations is not uncommon. I have therefore put some code into my error logging function that detects identical errors and skips writing them to the error log.
My standard error handler that is used on every procedure looks like this. It records the error type, procedure the error occurred in and any parameters the procedure received (FileType in this case).
procerr:
Call NewErrorLog(Err.number, Err.Description, "GetOutputFileType", FileType)
Resume exitproc
My error logging function which writes to a table (I am in ms-access) is as follows. It uses static variables to retain the previous values of error data and compare them to current versions. The first error is logged, then the second identical error pushes the application into debug mode if I am the user or if in other user mode, quits the application.
Public Function NewErrorLog(ErrCode As Variant, ErrDesc As Variant, Optional Source As Variant = "", Optional ErrData As Variant = Null) As Boolean
On Error GoTo errLogError
'Records errors from application code
Dim dbs As Database
Dim rst As Recordset
Dim ErrorLogID As Long
Dim StackInfo As String
Dim MustQuit As Boolean
Dim i As Long
Static ErrCodeOld As Long
Static SourceOld As String
Static ErrDataOld As String
'Detects errors that occur in loops and records only the first two.
If Nz(ErrCode, 0) = ErrCodeOld And Nz(Source, "") = SourceOld And Nz(ErrData, "") = ErrDataOld Then
NewErrorLog = True
MsgBox "Error has occured in a loop: " & Nz(ErrCode, 0) & Space(1) & Nz(ErrDesc, "") & ": " & Nz(Source, "") & "[" & Nz(ErrData, "") & "]", vbExclamation, Appname
If Not gDeveloping Then 'Allow debugging
Stop
Exit Function
Else
ErrDesc = "[loop]" & Nz(ErrDesc, "") 'Flag this error as coming from a loop
MsgBox "Error has been logged, now Quiting", vbInformation, Appname
MustQuit = True 'will Quit after error has been logged
End If
Else
'Save current values to static variables
ErrCodeOld = Nz(ErrCode, 0)
SourceOld = Nz(Source, "")
ErrDataOld = Nz(ErrData, "")
End If
'From FMS tools pushstack/popstack - tells me the names of the calling procedures
For i = 1 To UBound(mCallStack)
If Len(mCallStack(i)) > 0 Then StackInfo = StackInfo & "\" & mCallStack(i)
Next
'Open error table
Set dbs = CurrentDb()
Set rst = dbs.OpenRecordset("tbl_ErrLog", dbOpenTable)
'Write the error to the error table
With rst
.AddNew
!ErrSource = Source
!ErrTime = Now()
!ErrCode = ErrCode
!ErrDesc = ErrDesc
!ErrData = ErrData
!StackTrace = StackInfo
.Update
.BookMark = .LastModified
ErrorLogID = !ErrLogID
End With
rst.Close: Set rst = Nothing
dbs.Close: Set dbs = Nothing
DoCmd.Hourglass False
DoCmd.Echo True
DoEvents
If MustQuit = True Then DoCmd.Quit
exitLogError:
Exit Function
errLogError:
MsgBox "An error occured whilst logging the details of another error " & vbNewLine & _
"Send details to Developer: " & Err.number & ", " & Err.Description, vbCritical, "Please e-mail this message to developer"
Resume exitLogError
End Function
Note that an error logger has to be the most bullet proofed function in your application as the application cannot gracefully handle errors in the error logger. For this reason, I use NZ() to make sure that nulls cannot sneak in. Note that I also add [loop] to the second identical error so that I know to look in the loops in the error procedure first.
Try adjusting the code at "SqlDbType" to match your DB type if necessary and use this code:
comm.Parameters.Add("@person",SqlDbType.VarChar).Value=MyName;
or:
comm.Parameters.AddWithValue("@person", Myname);
That should work but remember with Command.Parameters.Add(), you can define the specific SqlDbType and with Command.Parameters.AddWithValue(), it will try get the SqlDbType based on parameter value implicitly which can break sometimes if it can not implicitly convert the datatype.
Hope this helps.

I created my variant of class for your needs. I believe it is a bit more configurable than already provided variants.
You can use it with all default settings just create an instance of a class and call StringifyDataTable
method, or you can set additional options if needed.
public class DataTableStringifier

public bool IsOuterBordersPresent { get; set; } //Whether outer borders of table needed
public bool IsHeaderHorizontalSeparatorPresent { get; set; } // Whether horizontal line separator between table title and data is needed. Useful to set 'false' if you expect only 1 or 2 rows of data - no need for additional lines then
public char ValueSeparator { get; set; } //Vertical line character
public char HorizontalLinePadChar { get; set; } // Horizontal line character
public char HorizontalLineSeparator { get; set; } // Horizontal border (between header and data) column separator (crossing of horizontal and vertical borders)
public int ValueMargin { get; set; } // Horizontal margin from table borders (inner and outer) to cell values

A programming language that is 'type-safe' means following things:
Try writing the properties as a comma separated list, then split the value after the properties file is loaded. For example
a=one,two,three
b=nine,ten,fourteen
You can also use org.apache.commons.configuration and change the value delimiter using the AbstractConfiguration.setListDelimiter(char) method if you're using comma in your values.
In my case I was stupid enough to create the patch file incorrectly in the first place, actually diff-ing the wrong way. I ended up with the exact same error messages.
If you're on master and do git diff branch-name > branch-name.patch
, this tries to remove all additions you want to happen and vice versa (which was impossible for git to accomplish since, obviously, never done additions cannot be removed).
So make sure you checkout to your branch and execute git diff master > branch-name.patch
AngularJS - Input number with 2 decimal places it could help... Filtering:
- Set the regular expression to validate the input using ng-pattern. Here I want to accept only numbers with a maximum of 2 decimal places and with a dot separator.
<input type="number" name="myDecimal" placeholder="Decimal" ng-model="myDecimal | number : 2" ng-pattern="/^[0-9]+(\.[0-9]{1,2})?$/" step="0.01" />
Reading forward this was pointed on the next answer ng-model="myDecimal | number : 2".
File capabilities are not ideal, because they can break after a package update.
The ideal solution, IMHO, should be an ability to create a shell with inheritable CAP_NET_BIND_SERVICE
set.
Here's a somewhat convoluted way to do this:
sg $DAEMONUSER "capsh --keep=1 --uid=`id -u $DAEMONUSER` \
--caps='cap_net_bind_service+pei' -- \
YOUR_COMMAND_GOES_HERE"
capsh
utility can be found in libcap2-bin package in Debian/Ubuntu distributions. Here's what goes on:
sg
changes effective group ID to that of the daemon user. This is necessary because capsh
leaves GID unchanged and we definitely do not want it.$DAEMONUSER
--keep=1
), except inheritable cap_net_bind_service
The result is a process with specified user and group, and cap_net_bind_service
privileges.
As an example, a line from ejabberd
startup script:
sg $EJABBERDUSER "capsh --keep=1 --uid=`id -u $EJABBERDUSER` --caps='cap_net_bind_service+pei' -- $EJABBERD --noshell -detached"
You're not saying how exactly putdata()
is not behaving. I'm assuming you're doing
>>> pic.putdata(a)
Traceback (most recent call last):
File "...blablabla.../PIL/Image.py", line 1185, in putdata
self.im.putdata(data, scale, offset)
SystemError: new style getargs format but argument is not a tuple
This is because putdata
expects a sequence of tuples and you're giving it a numpy array. This
>>> data = list(tuple(pixel) for pixel in pix)
>>> pic.putdata(data)
will work but it is very slow.
As of PIL 1.1.6, the "proper" way to convert between images and numpy arrays is simply
>>> pix = numpy.array(pic)
although the resulting array is in a different format than yours (3-d array or rows/columns/rgb in this case).
Then, after you make your changes to the array, you should be able to do either pic.putdata(pix)
or create a new image with Image.fromarray(pix)
.
I got the solution for onunload
in all browsers except Opera by changing the Ajax asynchronous request into synchronous request.
xmlhttp.open("POST","LogoutAction",false);
It works well for all browsers except Opera.
Using Helper class you can access SQLite Database and can perform the various operations on it by overriding the onCreate() and onUpgrade() methods.

I try this clipboard 0.0.4 and it works well.

yes stale element error is thrown when (taking your scenario) you have defined locator strategy to click on 'Add Item' first and then when you close the pop up the page gets refreshed hence the reference defined for 'Add Item' is lost in the memory so to overcome this you have to redefine the locator strategy for 'Add Item' again
understand it with a dummy code
// clicking on view details
driver.findElement(By.id("")).click();
// closing the pop up
driver.findElement(By.id("")).click();
// and when you try to click on Add Item
driver.findElement(By.id("")).click();
// you get stale element exception as reference to add item is lost
// so to overcome this you have to re identify the locator strategy for add item
// Please note : this is one of the way to overcome stale element exception
// Step 1 please add a universal wait in your script like below
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS); // just after you have initiated browser
I spent a long time looking for solutions, and found this answer.
It looks like, in order to get what you (and I) want, you need the combination of plt.ion()
, plt.show()
(not with block=False
) and, most importantly, plt.pause(.001)
(or whatever time you want). The pause is needed because the GUI events happen while the main code is sleeping, including drawing. It's possible that this is implemented by picking up time from a sleeping thread, so maybe IDEs mess with that—I don't know.
Here's an implementation that works for me on python 3.5:
import numpy as np
from matplotlib import pyplot as plt
def main():
plt.axis([-50,50,0,10000])
plt.ion()
plt.show()
x = np.arange(-50, 51)
for pow in range(1,5): # plot x^1, x^2, ..., x^4
y = [Xi**pow for Xi in x]
plt.plot(x, y)
plt.draw()
plt.pause(0.001)
input("Press [enter] to continue.")
if __name__ == '__main__':
main()
The better way of doing this without jQuery:
const images = document.getElementsByTagName('img');
for (let i = 0; i < images.length; i++) {
images[i].addEventListener('contextmenu', event => event.preventDefault());
}
This is a working solution of AES encryption
- implemented using openssl
. It uses the Cipher Block Chaining Mode (CBC-Mode). Thus, alongside data
and key
, you can specify iv

Sample usage:
<?php
$data = json_encode(['first_name'=>'Dunsin','last_name'=>'Olubobokun','country'=>'Nigeria']);
$inputKey = "W92ZB837943A711B98D35E799DFE3Z18";

$enc = $aes->encrypt();
$aes->setData($enc);
$dec=$aes->decrypt();
echo "After encryption: ".$enc."<br/>";
echo "After decryption: ".$dec."<br/>";
You can set the format you want:
dataGridViewCellStyle.Format = "dd/MM/yyyy";
this.date.DefaultCellStyle = dataGridViewCellStyle;
// date being a System.Windows.Forms.DataGridViewTextBoxColumn
Basically the Kernel is the interface between hardware (devices which are available in Computer) and Application software is like MS Office, Visual Studio, etc.
If I answer "what is an OS?" then the answer could be the same. Hence the kernel is the part & core of the OS.
The very sensitive tasks of an OS like memory management, I/O management, process management are taken care of by the kernel only.
So the ultimate difference is:
So to have a specific column come first, then the rest alphabetically, I'd propose this solution:
test[, c("myFirstColumn", sort(setdiff(names(test), "myFirstColumn")))]
if using logging.config.fileConfig with a configuration file use something like:
[formatter_simpleFormatter]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
datefmt=%Y-%m-%d %H:%M:%S
We don't have this problem if we are testing our client request with localhost
destination address (host
or hostname
on node.js) and our server common name is CN = localhost
in the server cert. But even if we change localhost
for 127.0.0.1
or any other IP we'll get error Hostname/IP doesn't match certificate's altnames
on node.js or SSL handshake failed
on QT.
I had the same issue about my server certificate on my client request. To solve it on my client node.js app I needed to put a subjectAltName
on my server_extension
with the following value:
[ server_extension ]
.
.
.
subjectAltName = @alt_names_server
[alt_names_server]
IP.1 = x.x.x.x
and then I use -extension
when I create and sign the certificate.
example:
In my case, I first export the issuer's config file because this file contents the server_extension
:
export OPENSSL_CONF=intermed-ca.cnf
so I create and sign my server cert:
openssl ca \
-in server.req.pem \
-out server.cert.pem \
-extensions server_extension \
-startdate `date +%y%m%d000000Z -u -d -2day` \
-enddate `date +%y%m%d000000Z -u -d +2years+1day`
It works fine on clients based on node.js with https requests but it doesn't work with clients based on QT QSsl when we define
sslConfiguration.setPeerVerifyMode(QSslSocket::VerifyPeer)
, unless we useQSslSocket::VerifyNone
it won't work. If we useVerifyNone
it will make our app to don't check the peer certificate so it'll accept any cert. So, to solve it I need to change my server common name on its cert and replace its value for the IP Address where my server is running.
for example:
CN = 127.0.0.1
As a small enhancement to the accepted answer that was subsequently refined by ahoffner - it is possible to use a date format rather than timestamp. The advantages are:
to do this, change the DB repeat_start
to be stored as type 'date' and repeat_interval
now hold days rather than seconds. i.e. 7 for a repeat of 7 days.
change the sql line:
WHERE (( 1370563200 - repeat_start) % repeat_interval = 0 )
to:
WHERE ( DATEDIFF( '2013-6-7', repeat_start ) % repeat_interval = 0)
everything else remains the same. Simples!
100% working solution
1) rm -rf /usr/local/lib/node_modules
2)brew uninstall node
3)echo prefix=~/.npm-packages >> ~/.npmrc
4)brew install node
5) npm install -g @angular/cli
Finally and most importantly
6) export PATH="$HOME/.npm-packages/bin:$PATH"
Also if any editor still shown err than write
7) point over there .

It's already late but if you just want to navigate through the file without editing it, cat

% cat filename | less
or alternatively simple:

The problem you describe can be solved by defining the template in the header, or via the approach you describe above.
I recommend reading the following points from the C++ FAQ Lite:
They go into a lot of detail about these (and other) template issues.
While you do the following, technically speaking:
<button ng-click="doSomething($event)"></button>
// In controller:
$scope.doSomething = function($event) {
//reference to the button that triggered the function:
$event.target
};
This is probably something you don't want to do as AngularJS philosophy is to focus on model manipulation and let AngularJS do the rendering (based on hints from the declarative UI). Manipulating DOM elements and attributes from a controller is a big no-no in AngularJS world.

You can design a lowpass Butterworth filter in runtime, using butter()
function, and then apply that to the signal.
fc = 300; % Cut off frequency
fs = 1000; % Sampling rate
[b,a] = butter(6,fc/(fs/2)); % Butterworth filter of order 6
x = filter(b,a,signal); % Will be the filtered signal
Highpass and bandpass filters are also possible with this method. See https://www.mathworks.com/help/signal/ref/butter.html
This sometimes happen in RStudio. In order to solve it you can attempt to plot to an external window (Windows-only):

DataContractJsonSerializer serializer =
new DataContractJsonSerializer(typeof(YourObjectType));
YourObjectType yourObject = (YourObjectType)serializer.ReadObject(jsonStream);
You could also use the JavaScriptSerializer
, but DataContractJsonSerializer
is supposedly better able to handle complex types.
Oddly enough JavaScriptSerializer was once deprecated (in 3.5) and then resurrected because of ASP.NET MVC (in 3.5 SP1). That would definitely be enough to shake my confidence and lead me to use DataContractJsonSerializer
since it is hard baked for WCF.
I read the answers. Then I noticed for me that the check box was already unchecked, but it still always reloaded the files. This is the Settings->Preferences->MISC->"Remember current session for next launch" check box on version 6.3.2. The following got rid of the problem:
1. Check the check box.
2. Exit the program.
3. Start the program again.
4. Uncheck the checkbox.
This is expected.
Refer to Javadocs for split
.
Splits this string around matches of the given regular expression.
This method works as if by invoking the two-argument split(java.lang.String,int) method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
The methods
in the Path class are syntactic, meaning that they operate on the Path instance. But eventually you must access the file
system to verify that a particular Path exists
File file = new File("FileName");
if(file.exists()){
System.out.println("file is already there");
}else{
System.out.println("Not find file ");
}
margin:auto;
text-align, if this won't work - try adding display:block;
and set there width:200px;
(in case your TD is too small).
bit
. It stores 1 or 0 (or NULL
).Alternatively, you could use the strings 'true'
and 'false'
in place of 1 or 0, like so-
declare @b1 bit = 'false'
print @b1 --prints 0
declare @b2 bit = 'true'
print @b2 --prints 1
Also, any non 0 value (either positive or negative) evaluates to (or converts to in some cases) a 1.
declare @i int = -42
print cast(@i as bit) --will print 1, because @i is not 0
Note that SQL Server uses three valued logic (true
, false
, and NULL
), since NULL
is a possible value of the bit
data type. Here are the relevant truth tables -
More information on three valued logic-

A better solution is to use the array_filter
function:
$display_related_tags =
array_filter($display_related_tags, function($e) use($found_tag){
return $e != $found_tag['name'];
});
As the php documentation reads:
As foreach relies on the internal array pointer in PHP 5, changing it within the loop may lead to unexpected behavior.
In PHP 7, foreach does not use the internal array pointer.
I tried to resolve with the suggested answer and still ran into some issues...
This was a solution to my problem:
ARG APP_EXE="AppName.exe"
ENV _EXE=${APP_EXE}
# Build a shell script because the ENTRYPOINT command doesn't like using ENV
RUN echo "#!/bin/bash \n mono ${_EXE}" > ./entrypoint.sh
RUN chmod +x ./entrypoint.sh
# Run the generated shell script.
ENTRYPOINT ["./entrypoint.sh"]
Specifically targeting your problem:
RUN echo "#!/bin/bash \n ./greeting --message ${ADDRESSEE}" > ./entrypoint.sh
RUN chmod +x ./entrypoint.sh
ENTRYPOINT ["./entrypoint.sh"]
If you want to use history while passing a function as a value to a Component's prop, with react-router 4 you can simply destructure the history
prop in the render attribute of the <Route/>
Component and then use history.push()
<Route path='/create' render={({history}) => (
<YourComponent
YourProp={() => {
this.YourClassMethod()
history.push('/')
}}>
</YourComponent>
)} />
Note: For this to work you should wrap React Router's BrowserRouter Component around your root component (eg. which might be in index.js)
Variant of the code of Vicent with one less memory allocation:
public static byte[] GetBytes<T>(T str)
{
int size = Marshal.SizeOf(str);
byte[] arr = new byte[size];
GCHandle h = default(GCHandle);
try
{
h = GCHandle.Alloc(arr, GCHandleType.Pinned);
Marshal.StructureToPtr<T>(str, h.AddrOfPinnedObject(), false);
}
finally
{
if (h.IsAllocated)
{
h.Free();
}
}
return arr;
}
public static T FromBytes<T>(byte[] arr) where T : struct
{
T str = default(T);
GCHandle h = default(GCHandle);
try
{
h = GCHandle.Alloc(arr, GCHandleType.Pinned);
str = Marshal.PtrToStructure<T>(h.AddrOfPinnedObject());
}
finally
{
if (h.IsAllocated)
{
h.Free();
}
}
return str;
}
I use GCHandle
to "pin" the memory and then I use directly its address with h.AddrOfPinnedObject()
.
For IPv4 addresses, you can use VARCHAR to store them as strings, but also look into storing them as long integesrs INT(11) UNSIGNED
. You can use MySQL's INET_ATON()
function to convert them to integer representation. The benefit of this is it allows you to do easy comparisons on them, like BETWEEN
queries
I have found the easiest/quickest way to bypass this is to exit the app within the simulator (2 x Cmd + Shift + H
) and re-launch.
Maybe you can use a work around and try something like:
import datetime
#import mysql
import MySQLdb
conn = MySQLdb.connect(host = '127.0.0.1',user = 'someUser', passwd = 'foobar',db = 'foobardb')
cursor = conn.cursor()
SELECT <rows> FROM TABLE_NAME WHERE ROWID=(SELECT MIN(ROWID) FROM TABLE_NAME)
UNION
SELECT <rows> FROM TABLE_NAME WHERE ROWID=(SELECT MAX(ROWID) FROM TABLE_NAME)
or
SELECT * FROM TABLE_NAME WHERE ROWID=(SELECT MIN(ROWID) FROM TABLE_NAME)
OR ROWID=(SELECT MAX(ROWID) FROM TABLE_NAME)
With version 1.7 of the official 10gen driver, this is the current (non-obsolete) API:
const string uri = "mongodb://localhost/mydb";
var client = new MongoClient(uri);
var db = client.GetServer().GetDatabase(new MongoUrl(uri).DatabaseName);
var collection = db.GetCollection("mycollection");

on shell works , sending to sdtout not , so that is one workaround, to write to stdout .
I made other approach, which is not run if sys.stdout.encoding is not define, or in others words , need export PYTHONIOENCODING=UTF-8 first to write to stdout.
import sys
if (sys.stdout.encoding is None):
print >> sys.stderr, "please set python env PYTHONIOENCODING=UTF-8, example: export PYTHONIOENCODING=UTF-8, when write to stdout."
exit(1)
so, using same example:

Give a class .border-lb
and give this CSS
.border-lb {border: 1px solid #ccc; border-width: 0 0 1px 1px;}
And the HTML
<table width="770">
<tr>
<td class="border-lb">picture (border only to the left and bottom ) </td>
<td>text</td>
</tr>
<tr>
<td>text</td>
<td class="border-lb">picture (border only to the left and bottom) </td>
</tr>
</table>
I disagree!
Why would you ignore the built-in functionality of a for loop to make your own? You do not need to reinvent the wheel.
I think it makes more sense to have your checks at the top of your for loop like so
for(int i = 0; i < myCollection.Length && myCollection[i].SomeValue != "Break Condition"; i++)
{
//loop body
}
or if you need to process the row first
for(int i = 0; i < myCollection.Length && (i == 0 ? true : myCollection[i-1].SomeValue != "Break Condition"); i++)
{
//loop body
}
This way you can write a function to perform everything and make much cleaner code.
for(int i = 0; i < myCollection.Length && (i == 0 ? true : myCollection[i-1].SomeValue != "Break Condition"); i++)
{
DoAllThatCrazyStuff(myCollection[i]);
}
Or if your condition is complicated you can move that code out too!
for(int i = 0; i < myCollection.Length && BreakFunctionCheck(i, myCollection); i++)
{
DoAllThatCrazyStuff(myCollection[i]);
}
"Professional Code" that is riddled with breaks doesn't really sound like professional code to me. It sounds like lazy coding ;)
Great solution is google-webfonts-helper .
It allows you to select more than one font variant, which saves a lot of time.
You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:
import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values
... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.
I am new to retrofit and I am enjoying it. So here is a simple way to understand it for those that might want to query with more than one query: The ? and & are automatically added for you.
Interface:
public interface IService {
String BASE_URL = "https://api.test.com/";
String API_KEY = "SFSDF24242353434";
@GET("Search") //i.e https://api.test.com/Search?
Call<Products> getProducts(@Query("one") String one, @Query("two") String two,
@Query("key") String key)
}
It will be called this way. Considering you did the rest of the code already.
Call<Results> call = service.productList("Whatever", "here", IService.API_KEY);
For example, when a query is returned, it will look like this.
//-> https://api.test.com/Search?one=Whatever&two=here&key=SFSDF24242353434

It's all about the linkage.
The previous answers provided good explainations about extern
.
But I want to add an important point.
You ask about extern
in C++ not in C and I don't know why there is no answer mentioning about the case when extern
comes with const
in C++.
In C++, a const
variable has internal linkage by default (not like C).
So this scenario will lead to linking error:
Source 1 :
const int global = 255; //wrong way to make a definition of global const variable in C++
Source 2 :
extern const int global; //declaration
It need to be like this:
Source 1 :
extern const int global = 255; //a definition of global const variable in C++
Source 2 :
extern const int global; //declaration
You should be using Maven, as the structure is standardized. To do that (Once you have created your Maven project in Netbeans, just
As long as the project has no errors, I usually get none transferring to eclipse. This works for Maven web projects and regular projects.
Caesar's solution is the best in my opinion, but if you still insist to use the strcpy
function, then after you have your strings ready:
string a = "text";
string b = "image";
You can try either:
strcpy(a.data(), b.data());
or
strcpy(a.c_str(), b.c_str());
Just call either the data()
or c_str()
member functions of the std::string
class, to get the char*
pointer of the string object.
The strcpy()
function doesn't have overload to accept two std::string
objects as parameters.
It has only one overload to accept two char*
pointers as parameters.
Both data
and c_str
return what does strcpy()
want exactly.
There are two ways in which this can be accomplished using vanilla javascript. The first is className
and the second is classList
. className
works in all browsers but can be unwieldy to work with when modifying an element's class attribute. classList
is an easier way to modify an element's class(es).
To outright set an element's class attribute, className
is the way to go, otherwise to modify an element's class(es), it's easier to use classList
.
Initial Html
<div id="ID"></div>
Setting the class attribute
var div = document.getElementById('ID');
div.className = "foo bar car";
Result:
<div id="ID" class="foo bar car"></div>
Adding a class
div.classList.add("car");// Class already exists, nothing happens
div.classList.add("tar");
Note: There's no need to test if a class exists before adding it. If a class needs to be added, just add it. If it already exists, a duplicate won't be added.
Result:
<div id="ID" class="foo bar car tar"></div>
Removing a class
div.classList.remove("car");
div.classList.remove("tar");
div.classList.remove("car");// No class of this name exists, nothing happens
Note: Just like add
, if a class needs to be removed, remove it. If it's there, it'll be removed, otherwise nothing will happen.
Result:
<div id="ID" class="foo bar"></div>
Checking if a class attribute contains a specific class
if (div.classList.contains("foo")) {
// Do stuff
}
Toggling a class
var classWasAdded = div.classList.toggle("bar"); // "bar" gets removed
// classWasAdded is false since "bar" was removed
classWasAdded = div.classList.toggle("bar"); // "bar" gets added
// classWasAdded is true since "bar" was added
.toggle
has a second boolean parameter that, in my opinion, is redundant and isn't worth going over.
For more information on classList
, check out MDN. It also covers browser compatibility if that's a concern, which can be addressed by using Modernizr for detection and a polyfill if needed.

GetUserId()
is an extension method on IIdentity
and it is in Microsoft.AspNet.Identity.IdentityExtensions
. Make sure you have added the namespace with using Microsoft.AspNet.Identity;
.
Instance method are methods which require an object of its class to be created before it can be called. Static methods are the methods in Java that can be called without creating an object of class.
Static method is declared with static keyword. Instance method is not with static keyword.
Static method means which will exist as a single copy for a class. But instance methods exist as multiple copies depending on the number of instances created for that class.
Static methods can be invoked by using class reference. Instance or non static methods are invoked by using object reference.
Static methods can’t access instance methods and instance variables directly. Instance method can access static variables and static methods directly.

My Python Solution:
def permutes(input,offset):
if( len(input) == offset ):
return [''.join(input)]
result=[]
for i in range( offset, len(input) ):
input[offset], input[i] = input[i], input[offset]
result = result + permutes(input,offset+1)
input[offset], input[i] = input[i], input[offset]
return result
# input is a "string"
# return value is a list of strings
def permutations(input):
return permutes( list(input), 0 )
# Main Program
print( permutations("wxyz") )

Since API Level 21 (Lollipop) Android provides a PdfRenderer class:
// create a new renderer
PdfRenderer renderer = new PdfRenderer(getSeekableFileDescriptor());
// let us just render all pages
final int pageCount = renderer.getPageCount();
for (int i = 0; i < pageCount; i++) {
Page page = renderer.openPage(i);
// say we render for showing on the screen
page.render(mBitmap, null, null, Page.RENDER_MODE_FOR_DISPLAY);
// do stuff with the bitmap
// close the page
page.close();
}
// close the renderer
renderer.close();
For more information see the sample app.
For older APIs I recommend Android PdfViewer library, it is very fast and easy to use, licensed under Apache License 2.0:
pdfView.fromAsset(String)
.pages(0, 2, 1, 3, 3, 3) // all pages are displayed by default
.enableSwipe(true)
.swipeHorizontal(false)
.enableDoubletap(true)
.defaultPage(0)
.onDraw(onDrawListener)
.onLoad(onLoadCompleteListener)
.onPageChange(onPageChangeListener)
.onPageScroll(onPageScrollListener)
.onError(onErrorListener)
.enableAnnotationRendering(false)
.password(null)
.scrollHandle(null)
.load();
Isn't easier than doing like :
1- Install jquery in your project:
yarn add jquery
2- Import jquery and start playing with DOM:

To connect to mongodb
with mongoose
, you can use :
mongoose.connect('mongodb://localhost/users_test');
or
mongoose.connect('localhost/users_test');
or
mongoose.connect('localhost','users_test');
But not mongoose.connect('mongodb:localhost/users_test');
, it doesnt match the right hostname (mongodb
instead of localhost
)
HTTP interceptors are now available via the new HttpClient
from @angular/common/http
, as of Angular 4.3.x versions and beyond.
It's pretty simple to add a header for every request now:
import {
HttpEvent,
HttpInterceptor,
HttpHandler,
HttpRequest,
} from '@angular/common/http';
import { Observable } from 'rxjs';
export class AddHeaderInterceptor implements HttpInterceptor {
intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
// Clone the request to add the new header
const clonedRequest = req.clone({ headers: req.headers.append('Authorization', 'Bearer 123') });
// Pass the cloned request instead of the original request to the next handle
return next.handle(clonedRequest);
}
}
There's a principle of immutability, that's the reason the request needs to be cloned before setting something new on it.
As editing headers is a very common task, there's actually a shortcut for it (while cloning the request):
const clonedRequest = req.clone({ setHeaders: { Authorization: 'Bearer 123' } });
After creating the interceptor, you should register it using the HTTP_INTERCEPTORS
provide.
import { HTTP_INTERCEPTORS } from '@angular/common/http';
@NgModule({
providers: [{
provide: HTTP_INTERCEPTORS,
useClass: AddHeaderInterceptor,
multi: true,
}],
})
export class AppModule {}
var x = parseInt(455/10);
The parseInt() function parses a string and returns an integer.
The radix parameter is used to specify which numeral system to be used, for example, a radix of 16 (hexadecimal) indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.
If the radix parameter is omitted, JavaScript assumes the following:
If the string begins with "0x", the radix is 16 (hexadecimal) If the string begins with "0", the radix is 8 (octal). This feature is deprecated If the string begins with any other value, the radix is 10 (decimal)
The simplest solution for this problem:
First make sure your sdk path is currect. Then Please close current project and in android startup menu click on import project and choose your project from explorer. This will always solve my problem
It looks like most of post here described what you need here. However - something you might need more complex behavior - depending on what you're parsing. In your case it might be so that you won't need more complex parsing - but it depends what information you're extracting.
You can use regex groups as field name in class, after which could be written for example like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text.RegularExpressions;
public class Info
{
public String Identifier;
public char nextChar;
};
class testRegex {
const string input = "Lorem ipsum dolor sit %download%#456 amet, consectetur adipiscing %download%#3434 elit. " +
"Duis non nunc nec mauris feugiat porttitor. Sed tincidunt blandit dui a viverra%download%#298. Aenean dapibus nisl %download%#893434 id nibh auctor vel tempor velit blandit.";
static void Main(string[] args)
{
Regex regex = new Regex(@"%download%#(?<Identifier>[0-9]*)(?<nextChar>.)(?<thisCharIsNotNeeded>.)");
List<Info> infos = new List<Info>();
foreach (Match match in regex.Matches(input))
{
Info info = new Info();
for( int i = 1; i < regex.GetGroupNames().Length; i++ )
{
String groupName = regex.GetGroupNames()[i];
FieldInfo fi = info.GetType().GetField(regex.GetGroupNames()[i]);
if( fi != null ) // Field is non-public or does not exists.
fi.SetValue( info, Convert.ChangeType( match.Groups[groupName].Value, fi.FieldType));
}
infos.Add(info);
}
foreach ( var info in infos )
{
Console.WriteLine(info.Identifier + " followed by '" + info.nextChar.ToString() + "'");
}
}
};
This mechanism uses C# reflection to set value to class. group name is matched against field name in class instance. Please note that Convert.ChangeType won't accept any kind of garbage.
If you want to add tracking of line / column - you can add extra Regex split for lines, but in order to keep for loop intact - all match patterns must have named groups. (Otherwise column index will be calculated incorrectly)
This will results in following output:
456 followed by ' '
3434 followed by ' '
298 followed by '.'
893434 followed by ' '
Use this code syntax.
$("<div></div>").html("YOUR MESSAGE").dialog();
this works but it append a node to the DOM. You can use a class and then or first remove all elements with that class. ex:
function simple_alert(msg)
{
$('div.simple_alert').remove();
$('<div></div>').html(is_valid.msg).dialog({dialogClass:'simple_alert'});
}
I've tried lots of different answers in different forums. I guess it depends on the machine your developing. But I haved used the statement
ax.lines = []
and works perfectly. I don't use cla()
cause it deletes all the definitions I've made to the plot
Ex.
pylab.setp(_self.ax.get_yticklabels(), fontsize=8)
but I've tried deleting the lines many times. Also using the weakref library to check the reference to that line while I was deleting but nothing worked for me.
Hope this works for someone else =D
Use the default method in the interface and get the EntityManager to get the opportunity to set the ResultTransformer, then you can return the pure POJO, like this:
final String sql = "SELECT g.*, gm.* FROM group g LEFT JOIN group_members gm ON g.group_id = gm.group_id and gm.user_id = ? WHERE g.group_id = ?";
default GroupDetails getGroupDetails(Integer userId, Integer groupId) {
return BaseRepository.getInstance().uniqueResult(sql, GroupDetails.class, userId, groupId);
}
And the BaseRepository.java is like this:
@PersistenceContext
public EntityManager em;
public <T> T uniqueResult(String sql, Class<T> dto, Object... params) {
Session session = em.unwrap(Session.class);
NativeQuery q = session.createSQLQuery(sql);
if(params!=null){
for(int i=0,len=params.length;i<len;i++){
Object param=params[i];
q.setParameter(i+1, param);
}
}
q.setResultTransformer(Transformers.aliasToBean(dto));
return (T) q.uniqueResult();
}
This solution does not impact any other methods in repository interface file.
None of these suggestions were working for me. I finally found something else I could do - dbms_output.put_line
. For example:
SET SERVEROUTPUT ON
begin
for i in (select dbms_metadata.get_ddl('INDEX', index_name, owner) as ddl from all_indexes where owner = 'MYUSER') loop
dbms_output.put_line(i.ddl);
end loop;
end;
/
Boom. It printed out everything I wanted - no truncating or anything like that. And that works straight in sqlplus
- no need to put it in a separate file or anything.
Simple: e.g. if div id 'mydiv'
jQuery.fancybox.open({href: "#mydiv"});
This also makes JS code functional which is inside div.
self.tableView.tableHeaderView = segmentedControl;
If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.

From what I understand, since Laravel 5 it's advised/good practice to use the global functions like:
response()->json($v);
view('path.to.blade');
redirect();
route();
cookie();
And, if anything, when using the functions instead of the static notation my IDE doesn't light up like a Christmas tree.
I resolve the problem. It's very simple . if do you checking care the problem may be because the auxiliar variable has whitespace. Why ? I don't know but yus must use the trim() method and will resolve the problem
You can use following formulas.
For Excel 2007 or later:
=IFERROR(VLOOKUP(D3,List!A:C,3,FALSE),"No Match")
For Excel 2003:
=IF(ISERROR(MATCH(D3,List!A:A, 0)), "No Match", VLOOKUP(D3,List!A:C,3,FALSE))
Note, that
List!A:C
in VLOOKUP
and returns value from column ? 3
VLOOKUP
equals to FALSE
, in that case VLOOKUP
will only find an exact match, and the values in the first column of List!A:C
do not need to be sorted (opposite to case when you're using TRUE
).As it was revealed to me in an answer to my related question, I feel you should use boost::conversion::try_lexical_convert

I made a node module to automate this task: mddir
node mddir "../relative/path/"
To install: npm install mddir -g
To generate markdown for current directory: mddir
To generate for any absolute path: mddir /absolute/path
To generate for a relative path: mddir ~/Documents/whatever.
The md file gets generated in your working directory.
Currently ignores node_modules, and .git folders.
If you receive the error 'node\r: No such file or directory', the issue is that your operating system uses different line endings and mddir can't parse them without you explicitly setting the line ending style to Unix. This usually affects Windows, but also some versions of Linux. Setting line endings to Unix style has to be performed within the mddir npm global bin folder.
Get npm bin folder path with:
npm config get prefix
Cd into that folder
brew install dos2unix
dos2unix lib/node_modules/mddir/src/mddir.js
This converts line endings to Unix instead of Dos
Then run as normal with: node mddir "../relative/path/".

To have the number of whole days between two dates (DateTime
objects):
((end_at - start_at).to_f / 1.day).floor
You can modify a sheet via code by taking these actions
In code this would be:
Sub UnProtect_Modify_Protect()
ThisWorkbook.Worksheets("Sheet1").Unprotect Password:="Password"
'Unprotect
ThisWorkbook.ActiveSheet.Range("A1").FormulaR1C1 = "Changed"
'Modify
ThisWorkbook.Worksheets("Sheet1").Protect Password:="Password"
'Protect
End Sub
The weakness of this method is that if the code is interrupted and error handling does not capture it, the worksheet could be left in an unprotected state.
The code could be improved by taking these actions
The code to do this would be:
Sub Re-Protect_Modify()
ThisWorkbook.Worksheets("Sheet1").Protect Password:="Password", _
UserInterfaceOnly:=True
'Protect, even if already protected
ThisWorkbook.ActiveSheet.Range("A1").FormulaR1C1 = "Changed"
'Modify
End Sub
This code renews the protection on the worksheet, but with the ‘UserInterfaceOnly’ set to true. This allows VBA code to modify the worksheet, while keeping the worksheet protected from user input via the UI, even if execution is interrupted.
This setting is lost when the workbook is closed and re-opened. The worksheet protection is still maintained.
So the 'Re-protection' code needs to be included at the start of any procedure that attempts to modify the worksheet or can just be run once when the workbook is opened.

=CONCATENATE(E2,"-",F2)But the & operator always concatenates strings. + often will work, but if there is a number in one of the cells, it won't work as expected.
Normally, IIS would use the process identity (the user account it is running the worker process as) to access protected resources like file system or network.
With passthrough authentication, IIS will attempt to use the actual identity of the user when accessing protected resources.
If the user is not authenticated, IIS will use the application pool identity instead. If pool identity is set to NetworkService or LocalSystem, the actual Windows account used is the computer account.
The IIS warning you see is not an error, it's just a warning. The actual check will be performed at execution time, and if it fails, it'll show up in the log.
You can also have several workspaces - so you can connect to one and have set "A" of projects - and then connect to a different set when ever you like.
In Ansible 2.x, you can use the block
for group of tasks:
- block:
- name: checkout repo
git:
repo: https://github.com/some/repo.git
version: master
dest: "{{ dst }}"
- name: change perms
file:
dest: "{{ dst }}"
state: directory
mode: 0755
owner: some_user
become: yes
become_user: some user
To avoid strange side-effects with closures in java variables referenced by an anonymous delegate must be marked as final, so to refer to lastPrice
and price within the timer task they need to be marked as final.
This obviously won't work for you because you wish to change them, in this case you should look at encapsulating them within a class.
public class Foo {
private PriceObject priceObject;
private double lastPrice;
private double price;
public Foo(PriceObject priceObject) {
this.priceObject = priceObject;
}
public void tick() {
price = priceObject.getNextPrice(lastPrice);
lastPrice = price;
}
}
now just create a new Foo as final and call .tick from the timer.
public static void main(String args[]){
int period = 2000;
int delay = 2000;
Price priceObject = new Price();
final Foo foo = new Foo(priceObject);
Timer timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
foo.tick();
}
}, delay, period);
}
How did you try it? Maybe you are working with \
and omit proper escaping.
Instead of
open('\\HOST\share\path\to\file')
use either Johnsyweb's solution with the /
s, or try one of
open(r'\\HOST\share\path\to\file')
or
open('\\\\HOST\\share\\path\\to\\file')
.
Just for the shake of completing the answer given by eipi10.
I was facing the same problem, without using scale_y_continuous
nor coord_cartesian
.
The conflict was coming from the x axis, where I defined limits = c(1, 30)
. It seems such limits do not provide enough space if you want to "dodge" your bars, so R still throws the error
Removed 8 rows containing missing values (geom_bar)
Adjusting the limits of the x axis to limits = c(0, 31)
solved the problem.
In conclusion, even if you are not putting limits to your y axis, check out your x axis' behavior to ensure you have enough space
I dont know why but it worked for me. If you have comments like
//Comment
Then it gives this error. To fix this do
/*Comment*/
Doesn't make sense but it worked for me.
This can be used in to solve this problem
<div id='scrol'></div>
in javascript use this
jQuery("div#scrol").scrollTop(jQuery("div#scrol")[0].scrollHeight);
If you're using SASS you could also use this mixin:
@mixin headings {
h1, h2, h3,
h4, h5, h6 {
@content;
}
}
Use it like so:
@include headings {
font: 32px/42px trajan-pro-1, trajan-pro-2;
}
Edit: My personal favourite way of doing this by optionally extending a placeholder selector on each of the heading elements.
h1, h2, h3,
h4, h5, h6 {
@extend %headings !optional;
}
Then I can target all headings like I would target any single class, for example:
.element > %headings {
color: red;
}
You can do it like that but storing a DataSet object in Session is not very efficient. If you have a web app with lots of users it will clog your server memory really fast.
If you really must do it like that I suggest removing it from the session as soon as you don't need the DataSet.
all multy key's probably fail, cause the put([key1, key2], val) and the get([null, key2]) end up using the equals of [key1, key2] and [null, key2]. If the backing map doesnt contains hash buckets per key then lookups are real slow to.
i think the way to go is using a index decorator (see the key1, key2 examples above) and if the extra index key's are properties of the stored value you can use the property name's and reflection to build the secondairy maps when you put(key, val) and add an extra method get(propertyname, propertyvalue) to use that index.
the return type of the get(propertyname, propertyvalue) could be a Collection so even none unique key's are indexed....

Also, you can use the following techniques to provision your service globally, before actual controllers are executed: https://stackoverflow.com/a/27050497/1056679. Just resolve your data globally and then pass it to your service in run

Comment if you want me to elaborate. I think the code is more or less self-explanatory, but then again I made it so I might be wrong :)
You can see it in action here.
The problem is that what you are trying to do shouldn't be done. You shouldn't be inflating fragments inside other fragments. From Android's documentation:
Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>. Nested fragments are only supported when added to a fragment dynamically.
While you may be able to accomplish the task with the hacks presented here, I highly suggest you don't do it. Its impossible to be sure that these hacks will handle what each new Android OS does when you try to inflate a layout for a fragment containing another fragment.
The only Android-supported way to add a fragment to another fragment is via a transaction from the child fragment manager.
Simply change your XML layout into an empty container (add an ID if needed):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mapFragmentContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</LinearLayout>
Then in the Fragment onViewCreated(View view, @Nullable Bundle savedInstanceState)
method:
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
FragmentManager fm = getChildFragmentManager();
SupportMapFragment mapFragment = (SupportMapFragment) fm.findFragmentByTag("mapFragment");
if (mapFragment == null) {
mapFragment = new SupportMapFragment();
FragmentTransaction ft = fm.beginTransaction();
ft.add(R.id.mapFragmentContainer, mapFragment, "mapFragment");
ft.commit();
fm.executePendingTransactions();
}
mapFragment.getMapAsync(callback);
}
I want to work with exec_query
of the ActiveRecord
class, because it returns the mapping of the query transforming into object, so it gets very practical and productive to iterate with the objects when the subject is Raw SQL.
Example:
values = ActiveRecord::Base.connection.exec_query("select * from clients")
p values
and return this complete query:
[{"id": 1, "name": "user 1"}, {"id": 2, "name": "user 2"}, {"id": 3, "name": "user 3"}]
To get only list of values
p values.rows
[[1, "user 1"], [2, "user 2"], [3, "user 3"]]
To get only fields columns
p values.columns
["id", "name"]
If you want to use some variable, you may use this way:
String value= "your value";
driver.execute_script("document.getElementById('q').value=' "+value+" ' ");
A clearer solution, works in ASP.Net Core 2.1 / 3.1
Filter class
using Microsoft.AspNetCore.Authorization;
// For ASP.NET 2.1
using Microsoft.AspNetCore.Http.Internal;
// For ASP.NET 3.1
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc.Filters;
public class ReadableBodyStreamAttribute : AuthorizeAttribute, IAuthorizationFilter
{
public void OnAuthorization(AuthorizationFilterContext context)
{
// For ASP.NET 2.1
// context.HttpContext.Request.EnableRewind();
// For ASP.NET 3.1
// context.HttpContext.Request.EnableBuffering();
}
}
In an Controller
[HttpPost]
[ReadableBodyStream]
public string SomePostMethod()
{
//Note: if you're late and body has already been read, you may need this next line
//Note2: if "Note" is true and Body was read using StreamReader too, then it may be necessary to set "leaveOpen: true" for that stream.
HttpContext.Request.Body.Seek(0, SeekOrigin.Begin);
using (StreamReader stream = new StreamReader(HttpContext.Request.Body))
{
string body = stream.ReadToEnd();
// body = "param=somevalue¶m2=someothervalue"
}
}
You can check it by compiling,and running this small C++ program.
#include <iostream>
#include <conio.h>
#include <cstdlib>
int show;
int main()
{
while(true)
{
int show = getch();
std::cout << show;
}
getch(); // Just to keep the console open after program execution
}
A cleaner alternative of putting your config file into a subfolder of src/main/resources would be to enhance your classpath locations. This is extremely easy to do with Maven.
For instance, place your property file in a new folder src/main/config, and add the following to your pom:
<build>
<resources>
<resource>
<directory>src/main/config</directory>
</resource>
</resources>
</build>
From now, every files files under src/main/config is considered as part of your classpath (note that you can exclude some of them from the final jar if needed: just add in the build section:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<excludes>
<exclude>my-config.properties</exclude>
</excludes>
</configuration>
</plugin>
</plugins>
so that my-config.properties can be found in your classpath when you run your app from your IDE, but will remain external from your jar in your final distribution).
Even though this is an old question, I'd like to give a solution:
string[] things= new string[] { "105", "101", "102", "103", "90" };
foreach (var thing in things.OrderBy(x => Int32.Parse(x) )
{
Console.WriteLine(thing);
}
Woha quite simple right? :D
The accepted answer is great for single renames, but here is a way to rename multiple images that have the same repository all at once (and remove the old images).
If you have old images of the form:
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
old_name/image_name_1 latest abcdefghijk1 5 minutes ago 1.00GB
old_name/image_name_2 latest abcdefghijk2 5 minutes ago 1.00GB
And you want:
new_name/image_name_1
new_name/image_name_2
Then you can use this (subbing in OLD_REPONAME
, NEW_REPONAME
, and TAG
as appropriate):
OLD_REPONAME='old_name'
NEW_REPONAME='new_name'
TAG='latest'
# extract image name, e.g. "old_name/image_name_1"
for image in $(docker images | awk '{ if( FNR>1 ) { print $1 } }' | grep $OLD_REPONAME)
do \
OLD_NAME="${image}:${TAG}" && \
NEW_NAME="${NEW_REPONAME}${image:${#OLD_REPONAME}:${#image}}:${TAG}" && \
docker image tag $OLD_NAME $NEW_NAME && \
docker rmi $image:${TAG} # omit this line if you want to keep the old image
done
Based on the answer from #squiguy, to get a true timestamp I would type cast it from float.
>>> import time
>>> ts = int(time.time())
>>> print(ts)

At least that's the concept.
I slightly updated the function provided by the "community wiki" (the best answer), just to round to the nearest 5 (or anything you like), with this exception : the rounded number will NEVER be superior to the original number.
This is useful in cases when it is needed to say that "a company is alive for 47 years" : I want the web page to display "is alive for more than 45 years", while avoiding lying in stating "is alive for more than 50 years".
So when you feed this function with 47, it will not return 50, but will return 45 instead.
'Rounds a number to the nearest unit, never exceeding the actual value
function RoundToNearestOrBelow(num, r)
'@param num Long/Integer/Double The number to be rounded
'@param r Long The rounding value
'@return OUT Long The rounded value
'Example usage :
' Round 47 to the nearest 5 : it will return 45
' Response.Write RoundToNearestBelow(47, 5)
Dim OUT : OUT = num
Dim rounded : rounded = Round((((num)) / r), 0) * r
if (rounded =< num) then
OUT = rounded
else
OUT = rounded - r
end if
'Return
RoundToNearestOrBelow = OUT
end function 'RoundToNearestOrBelow

You can simply use one of the system dependent end-of-file indicators ( d for Unix/Linux/Ubuntu, z for windows) to make the while statement false. This should get you out of the loop nicely. :)

This is the 2nd of two answers.
If you want to just strip all namespaces arbitrarily from a document during serialization, you can do this by implementing your own XmlWriter.
The easiest way is to derive from XmlTextWriter and override the StartElement method that emits namespaces. The StartElement method is invoked by the XmlSerializer when emitting any elements, including the root. By overriding the namespace for each element, and replacing it with the empty string, you've stripped the namespaces from the output.
public class NoNamespaceXmlWriter : XmlTextWriter
{
//Provide as many contructors as you need
public NoNamespaceXmlWriter(System.IO.TextWriter output)
: base(output) { Formatting= System.Xml.Formatting.Indented;}
public override void WriteStartDocument () { }
public override void WriteStartElement(string prefix, string localName, string ns)
{
base.WriteStartElement("", localName, "");
}
}
Suppose this is the type:
// explicitly specify a namespace for this type,
// to be used during XML serialization.
[XmlRoot(Namespace="urn:Abracadabra")]
public class MyTypeWithNamespaces
{
// private fields backing the properties
private int _Epoch;
private string _Label;
// explicitly define a distinct namespace for this element
[XmlElement(Namespace="urn:Whoohoo")]
public string Label
{
set { _Label= value; }
get { return _Label; }
}
// this property will be implicitly serialized to XML using the
// member name for the element name, and inheriting the namespace from
// the type.
public int Epoch
{
set { _Epoch= value; }
get { return _Epoch; }
}
}
Here's how you would use such a thing during serialization:
var o2= new MyTypeWithNamespaces { ..intializers.. };
var builder = new System.Text.StringBuilder();
using ( XmlWriter writer = new NoNamespaceXmlWriter(new System.IO.StringWriter(builder)))
{
s2.Serialize(writer, o2, ns2);
}
Console.WriteLine("{0}",builder.ToString());
The XmlTextWriter is sort of broken, though. According to the reference doc, when it writes it does not check for the following:
Invalid characters in attribute and element names.
Unicode characters that do not fit the specified encoding. If the Unicode characters do not fit the specified encoding, the XmlTextWriter does not escape the Unicode characters into character entities.
Duplicate attributes.
Characters in the DOCTYPE public identifier or system identifier.
These problems with XmlTextWriter have been around since v1.1 of the .NET Framework, and they will remain, for backward compatibility. If you have no concerns about those problems, then by all means use the XmlTextWriter. But most people would like a bit more reliability.
To get that, while still suppressing namespaces during serialization, instead of deriving from XmlTextWriter, define a concrete implementation of the abstract XmlWriter and its 24 methods.
An example is here:
public class XmlWriterWrapper : XmlWriter
{
protected XmlWriter writer;
public XmlWriterWrapper(XmlWriter baseWriter)
{
this.Writer = baseWriter;
}
public override void Close()
{
this.writer.Close();
}
protected override void Dispose(bool disposing)
{
((IDisposable) this.writer).Dispose();
}
public override void Flush()
{
this.writer.Flush();
}
public override string LookupPrefix(string ns)
{
return this.writer.LookupPrefix(ns);
}
public override void WriteBase64(byte[] buffer, int index, int count)
{
this.writer.WriteBase64(buffer, index, count);
}
public override void WriteCData(string text)
{
this.writer.WriteCData(text);
}
public override void WriteCharEntity(char ch)
{
this.writer.WriteCharEntity(ch);
}
public override void WriteChars(char[] buffer, int index, int count)
{
this.writer.WriteChars(buffer, index, count);
}
public override void WriteComment(string text)
{
this.writer.WriteComment(text);
}
public override void WriteDocType(string name, string pubid, string sysid, string subset)
{
this.writer.WriteDocType(name, pubid, sysid, subset);
}
public override void WriteEndAttribute()
{
this.writer.WriteEndAttribute();
}
public override void WriteEndDocument()
{
this.writer.WriteEndDocument();
}
public override void WriteEndElement()
{
this.writer.WriteEndElement();
}
public override void WriteEntityRef(string name)
{
this.writer.WriteEntityRef(name);
}
public override void WriteFullEndElement()
{
this.writer.WriteFullEndElement();
}
public override void WriteProcessingInstruction(string name, string text)
{
this.writer.WriteProcessingInstruction(name, text);
}
public override void WriteRaw(string data)
{
this.writer.WriteRaw(data);
}
public override void WriteRaw(char[] buffer, int index, int count)
{
this.writer.WriteRaw(buffer, index, count);
}
public override void WriteStartAttribute(string prefix, string localName, string ns)
{
this.writer.WriteStartAttribute(prefix, localName, ns);
}
public override void WriteStartDocument()
{
this.writer.WriteStartDocument();
}
public override void WriteStartDocument(bool standalone)
{
this.writer.WriteStartDocument(standalone);
}
public override void WriteStartElement(string prefix, string localName, string ns)
{
this.writer.WriteStartElement(prefix, localName, ns);
}
public override void WriteString(string text)
{
this.writer.WriteString(text);
}
public override void WriteSurrogateCharEntity(char lowChar, char highChar)
{
this.writer.WriteSurrogateCharEntity(lowChar, highChar);
}
public override void WriteValue(bool value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(DateTime value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(decimal value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(double value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(int value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(long value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(object value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(float value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(string value)
{
this.writer.WriteValue(value);
}
public override void WriteWhitespace(string ws)
{
this.writer.WriteWhitespace(ws);
}
public override XmlWriterSettings Settings
{
get
{
return this.writer.Settings;
}
}
protected XmlWriter Writer
{
get
{
return this.writer;
}
set
{
this.writer = value;
}
}
public override System.Xml.WriteState WriteState
{
get
{
return this.writer.WriteState;
}
}
public override string XmlLang
{
get
{
return this.writer.XmlLang;
}
}
public override System.Xml.XmlSpace XmlSpace
{
get
{
return this.writer.XmlSpace;
}
}
}
Then, provide a derived class that overrides the StartElement method, as before:
public class NamespaceSupressingXmlWriter : XmlWriterWrapper
{
//Provide as many contructors as you need
public NamespaceSupressingXmlWriter(System.IO.TextWriter output)
: base(XmlWriter.Create(output)) { }
public NamespaceSupressingXmlWriter(XmlWriter output)
: base(XmlWriter.Create(output)) { }
public override void WriteStartElement(string prefix, string localName, string ns)
{
base.WriteStartElement("", localName, "");
}
}
And then use this writer like so:
var o2= new MyTypeWithNamespaces { ..intializers.. };
var builder = new System.Text.StringBuilder();
var settings = new XmlWriterSettings { OmitXmlDeclaration = true, Indent= true };
using ( XmlWriter innerWriter = XmlWriter.Create(builder, settings))
using ( XmlWriter writer = new NamespaceSupressingXmlWriter(innerWriter))
{
s2.Serialize(writer, o2, ns2);
}
Console.WriteLine("{0}",builder.ToString());

Use sed's substitution: sed 's/"//g'
s/X/Y/
replaces X with Y.
g
means all occurrences should be replaced, not just the first one.
There are two obvious points, as well as the points in the other answer:
They are exactly equivalent when using sub queries:
SELECT * FROM table
WHERE column IN(subquery);
SELECT * FROM table
WHERE column = ANY(subquery);
On the other hand:
Only the IN
operator allows a simple list:
SELECT * FROM table
WHERE column IN(… , … , …);
Presuming they are exactly the same has caught me out several times when forgetting that ANY
doesn’t work with lists.

If you have a custom struct or class and want to sort them arbitrarily, you should call sort() using a trailing closure that sorts on a field you specify. Here's an example using an array of custom structs that sorts on a particular property:
struct User {
var firstName: String
}
var users = [
User(firstName: "Jemima"),
User(firstName: "Peter"),
User(firstName: "David"),
User(firstName: "Kelly"),
User(firstName: "Isabella")
]
users.sort {
$0.firstName < $1.firstName
}
If you want to return a sorted array rather than sort it in place, use sorted() like this:
let sortedUsers = users.sorted {
$0.firstName < $1.firstName
}
This error can be because of no SSH key on the your local machine. Check the SSH key locally:
$ cat ~/.ssh/id_rsa.pub
If above command do not give any output use below command to create ssh key(Linux/Mac):
$ ssh-keygen
Now again run cat ~/.ssh/id_rsa.pub This is your SSH key. Copy and add this key to your SSH keys in on git. In gitlab/bitbucket go to
profile settings -> SSH Keys -> add Key
and add the key
When i use these solution this error coming:

%timeit df[(df['Gender']=='Male') & (df['Year']==2014)]
Results for 100,000 rows:
6.67 ms ± 557 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
5.54 ms ± 536 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
Results for 10,000,000 rows:
326 ms ± 6.52 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
472 ms ± 25.1 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
So results depend on the size and the data. On my laptop, query()
gets faster after 500k rows. Further, the string search in Year=="2014"
has an unnecessary overhead (Year==2014
is faster).
svn export
simply extracts all the files from a revision and does not allow revision control on it. It also does not litter each directory with .svn directories.
svn checkout
allows you to use version control in the directory made, e.g. your standard commands such as svn update
and svn commit
.

use IDLE Editor {You may already have it} it has interactive shell for python and it will show you execution and result.
You can do it using a table, but it is not pure CSS.
<style>
ul{
text-indent: 40px;
}
li{
list-style-type: none;
padding: 0;
}
span{

position: relative;
left: -40px;
}
</style>
<ul>
<span></span><li>The lazy dog.</li>
<span>AND</span><li>The lazy cat.</li>
<span>OR</span><li>The active goldfish.</li>
</ul>
Note that it doesn't display exactly like you want, because it switches line on each option. However, I hope that this helps you come closer to the answer.
System.String is a reference type and already "nullable".
Nullable<T> and the ? suffix are for value types such as Int32, Double, DateTime, etc.
Try, Its working for me.
[[self.textField valueForKey:@"textInputTraits"] setValue:[UIColor redColor] strong textforKey:@"insertionPointColor"];
Upon investigation, it's also worth noting that when you want to start using docker in a new terminal window, the correct command is:
$(boot2docker shellinit)
I had tested these commands:
>> docker info
Get http:///var/run/docker.sock/v1.15/info: dial unix /var/run/docker.sock: no such file or directory
>> boot2docker shellinit
Writing /Users/ddavison/.boot2docker/certs/boot2docker-vm/ca.pem

>> docker info

Notice that docker info returned that same error. however.. when using $(boot2docker shellinit)

Here are some instructions on how to initiate a GitHub repository and then push code you've already created to it. The first set of instructions are directly from GitHub.
Source: https://help.github.com/articles/create-a-repo/
In the upper-right corner of any page, click, and then click New repository.
Create a short, memorable name for your repository. For example, "hello-world".
Optionally, add a description of your repository. For example, "My first repository on GitHub."
Choose between creating a public or private repository.
Initialize this repository with a README.
Create repository.
Congratulations! You've successfully created your first repository, and initialized it with a README file.
Now after these steps you will want to push the code on your local computer up to the repository you just created and you do this following these steps:
git init
(in the root folder where your code is located)
git add -A
(this will add all the files and folders in your directory to be committed)
git commit -am "First Project commit"
git remote add origin [email protected]:YourGithubName/your-repo-name.git
(you'll find this address on the GitHub repository you just created under "ssh clone URL" on the main page)
git push -u origin master
That's it. Your code will now be pushed up to GitHub. Now every time you want to keep pushing code that has changed just do.
git commit -m "New changes"
git push origin master
(if master is the branch you are working on)
One can also nullify parent's line height:
#wrapper {
line-height: 0;
}

I found this to be working from jquery site
$.getJSON( "/Admin/GetFolderList/", function( data ) {
var options = $("#dropdownID");
$.each( data, function(key, val) {
options.append(new Option(key, val));
});
});
Your problem comes from the 32/64 bit version of your JDK/JRE... Your shared lib is searched for a 32 bit version.
Your default JDK is a 32 bit version. Try to install a 64 bit one by default and relaunch your `.sh file.
Const-correct C/C++ pointer solution. Minimal operations in loop.
int IsPalindrome (const char *str)
{
const unsigned len = strlen(str);
const char *end = &str[len-1];
while (str < end)
if (*str++ != *end--)
return 0;
return 1;
}
First, you are strongly discouraged to do almost any cast, so you should limit it as much as possible! You lose the benefits of Java's compile-time strongly-typed features.
In any case, Class.cast()
should be used mainly when you retrieve the Class
token via reflection. It's more idiomatic to write
MyObject myObject = (MyObject) object
rather than
MyObject myObject = MyObject.class.cast(object)
EDIT: Errors at compile time
Over all, Java performs cast checks at run time only. However, the compiler can issue an error if it can prove that such casts can never succeed (e.g. cast a class to another class that's not a supertype and cast a final class type to class/interface that's not in its type hierarchy). Here since Foo
and Bar
are classes that aren't in each other hierarchy, the cast can never succeed.
An alternative implementation of what @user252400 proposes is to use bwrap
, a small setuid sandbox that can be found in all major distributions - often installed by default. bwrap
allows you to bind mount directories without sudo
and automatically unbinds them when git or your shell exits.
Assuming your development process isn't too crazy (see bellow), start bash in a private namespace and bind the external directory under the git directory:
bwrap --ro-bind / / \
--bind {EXTERNAL-DIR} {MOUNTPOINT-IN-GIT-DIR} \
--dev /dev \
bash
Then do everything you'd do normally like git add
, git commit
, and so on. When you're done, just exit bash. Clean and simple.
Caveats: To prevent sandbox escapes, bwrap
is not allowed to execute other setuid binaries. See man bwrap
for more details.
These messages are rather misleading and understandably a source of confusion. Older Ubuntu versions used Libav which is a fork of the FFmpeg project. FFmpeg returned in Ubuntu 15.04 "Vivid Vervet".
The fork was basically a non-amicable result of conflicting personalities and development styles within the FFmpeg community. It is worth noting that the maintainer for Debian/Ubuntu switched from FFmpeg to Libav on his own accord due to being involved with the Libav fork.
ffmpeg
vs the fake oneFor a while both Libav and FFmpeg separately developed their own version of ffmpeg
.
Libav then renamed their bizarro ffmpeg
to avconv
to distance themselves from the FFmpeg project. During the transition period the "not developed anymore" message was displayed to tell users to start using avconv
instead of their counterfeit version of ffmpeg
. This confused users into thinking that FFmpeg (the project) is dead, which is not true. A bad choice of words, but I can't imagine Libav not expecting such a response by general users.
This message was removed upstream when the fake "ffmpeg
" was finally removed from the Libav source, but, depending on your version, it can still show up in Ubuntu because the Libav source Ubuntu uses is from the ffmpeg-to-avconv transition period.
In June 2012, the message was re-worded for the package libav - 4:0.8.3-0ubuntu0.12.04.1
. Unfortunately the new "deprecated" message has caused additional user confusion.
Starting with Ubuntu 15.04 "Vivid Vervet", FFmpeg's ffmpeg
is back in the repositories again.
To further complicate matters, Libav chose a name that was historically used by FFmpeg to refer to its libraries (libavcodec, libavformat, etc). For example the libav-user mailing list, for questions and discussions about using the FFmpeg libraries, is unrelated to the Libav project.
If you are using avconv
then you are using Libav. If you are using ffmpeg
you could be using FFmpeg or Libav. Refer to the first line in the console output to tell the difference: the copyright notice will either mention FFmpeg or Libav.
Secondly, the version numbering schemes differ. Each of the FFmpeg or Libav libraries contains a version.h
header which shows a version number. FFmpeg will end in three digits, such as 57.67.100, and Libav will end in one digit such as 57.67.0. You can also view the library version numbers by running ffmpeg
or avconv
and viewing the console output.
ffmpeg
The real ffmpeg
is in the repository, so you can install it with:
apt-get install ffmpeg
Your options are:
ffmpeg
,ffmpeg
,These methods are non-intrusive, reversible, and will not interfere with the system or any repository packages.
Another possible option is to upgrade to Ubuntu 15.04 "Vivid Vervet" or newer and just use ffmpeg
from the repository.
For an interesting blog article on the situation, as well as a discussion about the main technical differences between the projects, see The FFmpeg/Libav situation.
Same Object Not Found problem here - both in Xampp as well as in Wamp. It turns out the root name of "phpmyadmin" was "PhpMyAdmin". I got rid of all the capitals, renaming the folder to "phpmyadmin", and after a couple of reloads phpmyadmin was working.
you can extend LinkedHashSet
adding your desired getIndex()
method. It's 15 minutes to implement and test it. Just go through the set using iterator and counter, check the object for equality. If found, return the counter.
