Even there exist an accepted answer, I'll like to demonstrate the following (with Python 2.7.2 and Numpy 1.6.0 on Vista):
In []: x= rand(1e5)
In []: %timeit isnan(x.min())
10000 loops, best of 3: 200 us per loop
In []: %timeit isnan(x.sum())
10000 loops, best of 3: 169 us per loop
In []: %timeit isnan(dot(x, x))
10000 loops, best of 3: 134 us per loop
In []: x[5e4]= NaN
In []: %timeit isnan(x.min())
100 loops, best of 3: 4.47 ms per loop
In []: %timeit isnan(x.sum())
100 loops, best of 3: 6.44 ms per loop
In []: %timeit isnan(dot(x, x))
10000 loops, best of 3: 138 us per loop
Thus, the really efficient way might be heavily dependent on the operating system. Anyway dot(.)
based seems to be the most stable one.
Bit of a late response but I noticed that this information can be hard to find and haven't found the answer on SO, so here it is.
Try a differnt parameter #view=FitH to force it to fit in the horzontal space and also you need to start the querystring off with a # rather than an & making it:
filename.pdf#view=FitH
What I've noticed it is that this will work if adobe reader is embedded in the browser but chrome will use it's own version of the reader and won't respond in the same way. In my own case, the chrome browser zoomed to fit width by default, so no problem , but Internet Explorer needed the above parameters to ensure the link always opened the pdf page with the correct view setting.
For a full list of available parameters see this doc
EDIT: (lazy mode on)
make sure that the imported R is not from another module. I had moved a class from a module to the main project, and the R was the one from the module.
This may be an option. Hope there is a better way to start from last element than to while loop to the end.
public static void main(String[] args) {
List<String> a = new ArrayList<String>();
a.add("1");a.add("2");a.add("3");a.add("4");a.add("5");
ListIterator<String> aIter=a.listIterator();
while(aIter.hasNext()) aIter.next();
for (;aIter.hasPrevious();)
{
String aVal = aIter.previous();
System.out.println(aVal);
}
}
With /^[a-zA-Z]/
you only check the first character:
^
: Assert position at the beginning of the string[a-zA-Z]
: Match a single character present in the list below:
a-z
: A character in the range between "a" and "z"A-Z
: A character in the range between "A" and "Z"If you want to check if all characters are letters, use this instead:
/^[a-zA-Z]+$/.test(str);
^
: Assert position at the beginning of the string[a-zA-Z]
: Match a single character present in the list below:
+
: Between one and unlimited times, as many as possible, giving back as needed (greedy)a-z
: A character in the range between "a" and "z"A-Z
: A character in the range between "A" and "Z"$
: Assert position at the end of the string (or before the line break at the end of the string, if any)Or, using the case-insensitive flag i
, you could simplify it to
/^[a-z]+$/i.test(str);
Or, since you only want to test
, and not match
, you could check for the opposite, and negate it:
!/[^a-z]/i.test(str);
sentence.sub! 'Robert', 'Joe'
Won't cause an exception if the replaced word isn't in the sentence (the []=
variant will).
The above replaces only the first instance of "Robert".
To replace all instances use gsub
/gsub!
(ie. "global substitution"):
sentence.gsub! 'Robert', 'Joe'
The above will replace all instances of Robert with Joe.
This is the easiest way to add a spinner i guess:-
You can use ng-show with the div tag of any one of these beautiful spinners http://tobiasahlin.com/spinkit/ {{This is not my page}}
and then you can use this kind of logic
//ajax start_x000D_
$scope.finderloader=true;_x000D_
_x000D_
$http({_x000D_
method :"POST",_x000D_
url : "your URL",_x000D_
data: { //your data_x000D_
_x000D_
}_x000D_
}).then(function mySucces(response) {_x000D_
$scope.finderloader=false;_x000D_
$scope.search=false; _x000D_
$scope.myData =response.data.records;_x000D_
});_x000D_
_x000D_
//ajax end _x000D_
_x000D_
<div ng-show="finderloader" class=spinner></div>_x000D_
//add this in your HTML at right place
_x000D_
I also had this error, and you helped me solve it. If formGroup or formGroupName are not written with the good case, then the name of the control is not found. Correct the case of formGroup or formGroupName and it is OK.
For those who intend to use venv
:
If you don't already have pip
for Python 3:
sudo apt install python3-pip
Install venv
package:
sudo apt install python3.7-venv
Create virtual environment (which will be bootstrapped with pip
by default):
python3.7 -m venv /path/to/new/virtual/environment
To activate the virtual environment, source
the appropriate script for the current shell, from the bin
directory of the virtual environment. The appropriate scripts for the different shells are:
bash/zsh – activate
fish – activate.fish
csh/tcsh – activate.csh
For example, if using bash:
source /path/to/new/virtual/environment/bin/activate
Optionally, to update pip
for the virtual environment (while it is activated):
pip install --upgrade pip
When you want to deactivate the virtual environment:
deactivate
If the case is:
n=int(input())
Instead of -> for i in n: -> gives error- 'int' object is not iterable
Use -> for i in range(0,n): -> works fine..!
Delete
operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirementsInsert
for arrays is basically Set
as mentioned in the beginningAt least with gcc 5.4 virtual functions could be template members but has to be templates themselves.
#include <iostream>
#include <string>
class first {
protected:
virtual std::string a1() { return "a1"; }
virtual std::string mixt() { return a1(); }
};
class last {
protected:
virtual std::string a2() { return "a2"; }
};
template<class T> class mix: first , T {
public:
virtual std::string mixt() override;
};
template<class T> std::string mix<T>::mixt() {
return a1()+" before "+T::a2();
}
class mix2: public mix<last> {
virtual std::string a1() override { return "mix"; }
};
int main() {
std::cout << mix2().mixt();
return 0;
}
Outputs
mix before a2
Process finished with exit code 0
For anyone using Koa and koa-passport:
Know that the key for the user set in the serializeUser method (often a unique id for that user) will be stored in:
this.session.passport.user
When you set in done(null, user)
in deserializeUser where 'user' is some user object from your database:
this.req.user
OR
this.passport.user
for some reason this.user
Koa context never gets set when you call done(null, user) in your deserializeUser method.
So you can write your own middleware after the call to app.use(passport.session()) to put it in this.user like so:
app.use(function * setUserInContext (next) {
this.user = this.req.user
yield next
})
If you're unclear on how serializeUser and deserializeUser work, just hit me up on twitter. @yvanscher
Seems like Firebug or whatever Debugger you are using, is not initialized properly. Are you sure Firebug is fully initialized when you try to access the console.log()-method? Check the Console-Tab (if it's set to activated).
Another possibility could be, that you overwrite the console-Object yourself anywhere in the code.
I came to the same problem and tried all methods on internet, and finally worked it out by accident. May you could try this(see in the picture)
You're missing comma (,
) inbetween:
>>> ((1,2) (2,3))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'tuple' object is not callable
Put comma:
>>> ((1,2), (2,3))
((1, 2), (2, 3))
It is better to use urlencode
here. Not much difference for single parameter but IMHO makes the code clearer. (It looks confusing to see a function quote_plus
! especially those coming from other languates)
In [21]: query='lskdfj/sdfkjdf/ksdfj skfj'
In [22]: val=34
In [23]: from urllib.parse import urlencode
In [24]: encoded = urlencode(dict(p=query,val=val))
In [25]: print(f"http://example.com?{encoded}")
http://example.com?p=lskdfj%2Fsdfkjdf%2Fksdfj+skfj&val=34
urlencode: https://docs.python.org/3/library/urllib.parse.html#urllib.parse.urlencode
quote_plus: https://docs.python.org/3/library/urllib.parse.html#urllib.parse.quote_plus
I just started using PowerShell with PowerShell Core 6.0 (beta) and following simply works:
if ($members.NoteProperty) {
# NoteProperty exist
}
or
if (-not $members.NoteProperty) {
# NoteProperty does not exist
}
Those steps should be able to be shortened down to:
hg pull
hg update -r MY_BRANCH -C
The -C
flag tells the update command to discard all local changes before updating.
However, this might still leave untracked files in your repository. It sounds like you want to get rid of those as well, so I would use the purge
extension for that:
hg pull
hg update -r MY_BRANCH -C
hg purge
In any case, there is no single one command you can ask Mercurial to perform that will do everything you want here, except if you change the process to that "full clone" method that you say you can't do.
You can now use Lambda Layers for this matters. Simply add a layer containing the package you need and it will run perfectly.
Follow this post: https://medium.com/@anjanava.biswas/nodejs-runtime-environment-with-aws-lambda-layers-f3914613e20e
Lot of concepts here which will be useful:
List<Object> list = new ArrayList<Object>(Arrays.asList(new String[]{"Java","is","cool"}));
String[] a = new String[list.size()];
list.toArray(a);
Tip to print array of Strings:
System.out.println(Arrays.toString(a));
req.query
is the query string sent to the server, example /page?
test=1, req.param
is the parameters passed to the handler.
app.get('/user/:id', handler);
, going to /user/blah
, req.param.id
would return blah
;
Even though the CSS attribute {position:fixed;}
seems (mostly) working on newer iOS devices, it is possible to have the device quirk and fallback to {position:relative;}
on occasion and without cause or reason. Usually clearing the cache will help, until something happens and the quirk happens again.
Specifically, from Apple itself Preparing Your Web Content for iPad:
Safari on iPad and Safari on iPhone do not have resizable windows. In Safari on iPhone and iPad, the window size is set to the size of the screen (minus Safari user interface controls), and cannot be changed by the user. To move around a webpage, the user changes the zoom level and position of the viewport as they double tap or pinch to zoom in or out, or by touching and dragging to pan the page. As a user changes the zoom level and position of the viewport they are doing so within a viewable content area of fixed size (that is, the window). This means that webpage elements that have their position "fixed" to the viewport can end up outside the viewable content area, offscreen.
What is ironic, Android devices do not seem to have this issue. Also it is entirely possible to use {position:absolute;}
when in reference to the body tag and not have any issues.
I found the root cause of this quirk; that it is the scroll event not playing nice when used in conjunction with the HTML or BODY tag. Sometimes it does not like to fire the event, or you will have to wait until the scroll swing event is finished to receive the event. Specifically, the viewport is re-drawn at the end of this event and fixed elements can be re-positioned somewhere else in the viewport.
So this is what I do: (avoid using the viewport, and stick with the DOM!)
<html>
<style>
.fixed{
position:fixed;
/*you can set your other static attributes here too*/
/*like height and width, margin, etc.*/
}
.scrollableDiv{
position:relative;
overflow-y:scroll;
/*all children will scroll within this like the body normally would.*/
}
.viewportSizedBody{
position:relative;
overflow:hidden;
/*this will prevent the body page itself from scrolling.*/
}
</style>
<body class="viewportSizedBody">
<div id="myFixedContainer" class="fixed">
This part is fixed.
</div>
<div id="myScrollableBody" class="scrollableDiv">
This part is scrollable.
</div>
</body>
<script type="text/javascript" src="{your path to jquery}/jquery-1.7.2.min.js"></script>
<script>
var theViewportHeight=$(window).height();
$('.viewportSizedBody').css('height',theViewportHeight);
$('#myScrollableBody').css('height',theViewportHeight);
</script>
</html>
In essence this will cause the BODY to be the size of the viewport and non-scrollable. The scrollable DIV nested inside will scroll as the BODY normally would (minus the swing effect, so the scrolling does stop on touchend.) The fixed DIV stays fixed without interference.
As a side note, a high z-index
value on the fixed DIV is important to keep the scrollable DIV appear to be behind it. I normally add in window resize and scroll events also for cross-browser and alternate screen resolution compatibility.
If all else fails, the above code will also work with both the fixed and scrollable DIVs set to {position:absolute;}
.
if you embed the pdf in your webpage and reference the object id, you should be able to do it.
eg. in your HTML:
<object ID="examplePDF" type="application/pdf" data="example.pdf" width="500" height="500">
in your javascript:
<script>
var pdf = document.getElementById("examplePDF");
pdf.print();
</script>
I hope that helps.
Write bytes and Create the file if not exists:
f = open('./put/your/path/here.png', 'wb')
f.write(data)
f.close()
wb
means open the file in write binary
mode.
There are 2 errors is this code:
1) You should remove this line, as it will reqrite x to an empty list:
x = []
2) In the first "if" statement, you should indent the "letter += 1" statement, like:
if x[i].isalpha():
letters += 1
AFAIK, this is not possible without root access. It would be a security issue to be able to have an app that cannot be exited with system buttons.
Edit, see here: Hide System Bar in Tablets
So, eventually I did that thing that all developers hate doing. I went and checked the server log files and found a report of a syntax error in line n.
tail -n 20 /var/log/apache2/error.log
It's quite easy, actually. You can use the System.IO.Directory
class in conjunction with System.IO.Path
. Something like (using LINQ makes it even easier):
var allFilenames = Directory.EnumerateFiles(path).Select(p => Path.GetFileName(p));
// Get all filenames that have a .txt extension, excluding the extension
var candidates = allFilenames.Where(fn => Path.GetExtension(fn) == ".txt")
.Select(fn => Path.GetFileNameWithoutExtension(fn));
There are many variations on this technique too, of course. Some of the other answers are simpler if your filter is simpler. This one has the advantage of the delayed enumeration (if that matters) and more flexible filtering at the expense of more code.
It's been a while since I C++'d but these answers are off a bit.
As far as the size goes, 'int' isn't anything. It's a notional value of a standard integer; assumed to be fast for purposes of things like iteration. It doesn't have a preset size.
So, the answers are correct with respect to the differences between int and uint, but are incorrect when they talk about "how large they are" or what their range is. That size is undefined, or more accurately, it will change with the compiler and platform.
It's never polite to discuss the size of your bits in public.
When you compile a program, int does have a size, as you've taken the abstract C/C++ and turned it into concrete machine code.
So, TODAY, practically speaking with most common compilers, they are correct. But do not assume this.
Specifically: if you're writing a 32 bit program, int will be one thing, 64 bit, it can be different, and 16 bit is different. I've gone through all three and briefly looked at 6502 shudder
A brief google search shows this: https://www.tutorialspoint.com/cprogramming/c_data_types.htm This is also good info: https://docs.oracle.com/cd/E19620-01/805-3024/lp64-1/index.html
use int if you really don't care how large your bits are; it can change.
Use size_t and ssize_t if you want to know how large something is.
If you're reading or writing binary data, don't use int. Use a (usually platform/source dependent) specific keyword. WinSDK has plenty of good, maintainable examples of this. Other platforms do too.
I've spent a LOT of time going through code from people that "SMH" at the idea that this is all just academic/pedantic. These ate the people that write unmaintainable code. Sure, it's easy to use type 'int' and use it without all the extra darn typing. It's a lot of work to figure out what they really meant, and a bit mind-numbing.
It's crappy coding when you mix int.
use int and uint when you just want a fast integer and don't care about the range (other than signed/unsigned).
Activator.CreateInstance()
returns an object, which doesn't have an Output method.
It looks like you come from dynamic programming languages? C# is definetly not that, and what you are trying to do will be difficult.
Since you are loading a specific dll from a specific location, maybe you just want to add it as a reference to your console application?
If you absolutely want to load the assembly via Assembly.Load
, you will have to go via reflection to call any members on c
Something like type.GetMethod("Output").Invoke(c, null);
should do it.
When using a <select>
tag that shows all options, here's a work around using <div>
instead:
HTML
<div id='sectionOptionsSelect' size='5' class='block1'
style='visibility: hidden; border: 1px solid gray; padding: 5px; '>
<span class='addPageBreakAbove'>Add Page Break Above</span>
<span class='addPageBreakBelow'>Add Page Break Below</span>
<span class='removeSection'>
<label class='fa fa-window-close'
style='font-size: 25px; color: red; background: white; '></label>
Remove Section</span>
</div>
Supporting JS
$('#sectionOptionsSelect span').hover(function () {
$(this).css('background', '#c0ec67');
}, function () {
$(this).css('background', 'transparent');
});
$('.removeSection').click(function () {
alert('removeSection');
});
CSS
#sectionOptionsSelect span {
display: block;
}
you can just do an svn add path/to/dir/*
you'll get warning about anything already in version control but it will add everything that isn't.
Step 1: Make a new folder and copy over the .apk file that you want to decode.
Now rename the extension of this .apk file to .zip (e.g. rename from filename.apk to filename.zip) and save it. Now you can access the classes.dex files, etc. At this stage you are able to see drawables but not xml and java files, so continue.
Step 2: Now extract this .zip file in the same folder (or NEW FOLDER).
Download https://github.com/pxb1988/dex2jar/releases/tag/2.0 : dex2jar-2.0
Now open command prompt and change directory to that folder (or NEW FOLDER). Then execute :
d2j-dex2jar.bat classes.dex
Download this decompiler http://java-decompiler.github.io/ to decompile classes-dex2jar.jar
Step 3: Now open another new folder
Put in the .apk file which you want to decode
Download the latest version of apktool AND apktool (https://ibotpeaches.github.io/Apktool/install/) install window (both can be downloaded from the same link) and place them in the same folder
Open a command window
Now run command like apktool if framework-res.apk (if you don't have it get it here)and next
apktool d myApp.apk (where myApp.apk denotes the filename that you want to decode)
now you get a file folder in that folder and can easily read the apk's xml files.
Copycontents of both folders to a single folder
Done !
Try adding in webpack, it solved the similar issue in my project. Specially the "presets" part.
module: {
loaders: [
{
test: /\.jsx?/,
include: APP_DIR,
loader: 'babel',
query :{
presets:['react','es2015']
}
},
The first one catches all subclasses of Throwable
(this includes Exception
and Error
), the second one catches all subclasses of Exception
.
Error
is programmatically unrecoverable in any way and is usually not to be caught, except for logging purposes (which passes it through again). Exception
is programmatically recoverable. Its subclass RuntimeException
indicates a programming error and is usually not to be caught as well.
You can use ROW_NUMBER(). You can specify where conditions as well. (e.g. Name LIKE'MyName%
in the following query)
SELECT *
FROM (SELECT ID, Name, Email,
ROW_NUMBER() OVER (PARTITION BY Email ORDER BY ID) AS RowNumber
FROM MyTable
WHERE Name LIKE 'MyName%') AS a
WHERE a.RowNumber = 1
The approach that I used for a modal presented view controller was to check the class of the presented controller. If the presented view controller was ViewController2
then I would execute some code.
UIViewController *vc = [self presentedViewController];
if ([vc isKindOfClass:[ViewController2 class]]) {
NSLog(@"this is VC2");
}
Leaving this here for info,
This error can also be caused if PostgreSQL server is on another machine and is not listening on external interfaces.
To debug this specific problem, you can follow theses steps:
sudo vim /etc/postgresql/9.3/main/postgresql.conf
listen_addresses = '*'
sudo /etc/init.d/postgresql restart
(Note, the commands above are for ubuntu. Other linux distro or OS may have different path to theses files)
Note: using '*'
for listening addresses will listen on all interfaces. If you do '0.0.0.0'
then it'll listen for all ipv4 and if you do '::'
then it'll listen for all ipv6.

If you want to set 777 permission to your created file than you can use the following method:
public void setPermission(File file) throws IOException{
Set<PosixFilePermission> perms = new HashSet<>();
perms.add(PosixFilePermission.OWNER_READ);
perms.add(PosixFilePermission.OWNER_WRITE);
perms.add(PosixFilePermission.OWNER_EXECUTE);
perms.add(PosixFilePermission.OTHERS_READ);
perms.add(PosixFilePermission.OTHERS_WRITE);
perms.add(PosixFilePermission.OTHERS_EXECUTE);
perms.add(PosixFilePermission.GROUP_READ);
perms.add(PosixFilePermission.GROUP_WRITE);
perms.add(PosixFilePermission.GROUP_EXECUTE);
Files.setPosixFilePermissions(file.toPath(), perms);
}
I used almost the same as @kmccoy, but instead of a keySet()
I did this
hashMap.values().toArray(new MyObject[0]);
A simpler way is to transverse the data, and hide the lines with the Visible
property.
// Prevent exception when hiding rows out of view
CurrencyManager currencyManager = (CurrencyManager)BindingContext[dataGridView3.DataSource];
currencyManager.SuspendBinding();
// Show all lines
for (int u = 0; u < dataGridView3.RowCount; u++)
{
dataGridView3.Rows[u].Visible = true;
x++;
}
// Hide the ones that you want with the filter you want.
for (int u = 0; u < dataGridView3.RowCount; u++)
{
if (dataGridView3.Rows[u].Cells[4].Value == "The filter string")
{
dataGridView3.Rows[u].Visible = true;
}
else
{
dataGridView3.Rows[u].Visible = false;
}
}
// Resume data grid view binding
currencyManager.ResumeBinding();
Just an idea... it works for me.
I just had the same issue. Use the flex align to center your elements. You need to use align-items: center
instead of align-content: center
. This will maintain the aspect ratio, while align-content will not keep the aspect ratio.
You don't need to write js to do that, simply use:
<a href="path_to/image.jpg" alt="something">Download image</a>
And the browser itself will automatically download the image.
If for some reason it doesn't work add the download attribute. With this attribute you can set a name for the downloadable file:
<a href="path_to/image.jpg" download="myImage">Download image</a>
arrayData.forEach((key : any, val: any) => {
key['index'] = val + 1;
arrayData2.forEach((keys : any, vals :any) => {
if (key.group_id == keys.id) {
key.group_name = keys.group_name;
}
})
})
This is not a search problem. The employer is wondering if you have a grasp of a checksum. You might need a binary or for loop or whatever if you were looking for multiple unique integers, but the question stipulates "one random empty slot." In this case we can use the stream sum. The condition: "The numbers are randomly added to the array" is meaningless without more detail. The question does not assume the array must start with the integer 1 and so tolerate with the offset start integer.
int[] test = {2,3,4,5,6,7,8,9,10, 12,13,14 };
/*get the missing integer*/
int max = test[test.length - 1];
int min = test[0];
int sum = Arrays.stream(test).sum();
int actual = (((max*(max+1))/2)-min+1);
//Find:
//the missing value
System.out.println(actual - sum);
//the slot
System.out.println(actual - sum - min);

Just updating the answer with simple method for find the date after no of months. As the best answer marked doesn't give the correct solution.
<?php
$date = date('2020-05-31');

$next = date("m",strtotime($date."+1 month"));
if($current==$next-1){
$needed = date('Y-m-d',strtotime($date." +1 month"));

}
echo "Date after 1 month from 2020-05-31 would be : $needed";

In case that you want combine a List of CompletableFutures, you can do this :
List<CompletableFuture<Void>> futures = new ArrayList<>();
// ... Add futures to this ArrayList of CompletableFutures
// CompletableFuture.allOf() method demand a variadic arguments
// You can use this syntax to pass a List instead
CompletableFuture<Void> allFutures = CompletableFuture.allOf(
futures.toArray(new CompletableFuture[futures.size()]));
// Wait for all individual CompletableFuture to complete
// All individual CompletableFutures are executed in parallel
allFutures.get();
For more details on Future & CompletableFuture, useful links:
1. Future: https://www.baeldung.com/java-future
2. CompletableFuture: https://www.baeldung.com/java-completablefuture

I've finally found some solid steps towards a clean solution to this problem.
This custom tool extends WCFProxyGenerator to provide an exception handling proxy. It generates an additional proxy called
ExceptionHandlingProxy<T>
which inheritsExceptionHandlingProxyBase<T>
- the latter of which implements the meat of the proxy's functionality. The result is that you can choose to use the default proxy that inheritsClientBase<T>
orExceptionHandlingProxy<T>
which encapsulates managing the lifetime of the channel factory and channel. ExceptionHandlingProxy respects your selections in the Add Service Reference dialog with respect to asynchronous methods and collection types.
Codeplex has a project called Exception Handling WCF Proxy Generator. It basically installs a new custom tool to Visual Studio 2008, then use this tool to generate the new service proxy (Add service reference). It has some nice functionality to deal with faulted channels, timeouts and safe disposal. There's an excellent video here called ExceptionHandlingProxyWrapper explaining exactly how this works.
You can safely use the Using
statement again, and if the channel is faulted on any request (TimeoutException or CommunicationException), the Wrapper will re-initialize the faulted channel and retry the query. If that fails then it will call the Abort()
command and dispose of the proxy and rethrow the Exception. If the service throws a FaultException
code it will stop executing, and the proxy will be aborted safely throwing the correct exception as expected.
PHP has catchable fatal errors. They are defined as E_RECOVERABLE_ERROR. The PHP manual describes an E_RECOVERABLE_ERROR as:
Catchable fatal error. It indicates that a probably dangerous error occured, but did not leave the Engine in an unstable state. If the error is not caught by a user defined handle (see also set_error_handler()), the application aborts as it was an E_ERROR.
You can "catch" these "fatal" errors by using set_error_handler() and checking for E_RECOVERABLE_ERROR. I find it useful to throw an Exception when this error is caught, then you can use try/catch.
This question and answer provides a useful example: How can I catch a "catchable fatal error" on PHP type hinting?
E_ERROR errors, however, can be handled, but not recovered from as the engine is in an unstable state.
np.where
function works as follows:
df['X'] = np.where(df['Y']>=50, 'yes', 'no')
In your case you would want:
import numpy as np
df['my_channel'] = np.where(df.my_channel > 20000, 0, df.my_channel)
I have solved same issue with following:
export M2_HOME=/usr/share/maven
for those users of windows 10 and WAMP that found this post, i have a solution.Please go visit this link. It worked for me and it was difficult to come to the solution but i hope it might be of help for others in the future.
For this error, I copied the latest libstdc++.so.6.0.17 from other server, and removed the soft link and recreated it.
1. Copy the the libstdc++.so.6.0.15 or latest from other server to the affected system.
In my case SUSE linux 11 SP3 had latest.
2. rm libstdc++.so.6
3. ln -s libstdc++.so.6.0.17 libstdc++.so.6 (under /usr/lib64 directory).

What you want to do is a combination of part of 1 and all of 2.
You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.
But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.
From the javadoc:
Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.
The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.
Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:
import static org.mockito.Mockito.*;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
class ClassWithStatics {
public static String getString() {
return "String";
}
public static int getInt() {
return 1;
}
}
@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
@Test
public void test() {
PowerMockito.mockStatic(ClassWithStatics.class);
when(ClassWithStatics.getString()).thenReturn("Hello!");
System.out.println("String: " + ClassWithStatics.getString());
System.out.println("Int: " + ClassWithStatics.getInt());
}
}
The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.
Let us make it simple if you're using Python 3
mydict = {'a':'apple','b':'boy','c':'cat'}
check = 'c' in mydict
if check:
print('c key is present')
If you need else condition
mydict = {'a':'apple','b':'boy','c':'cat'}
if 'c' in mydict:
print('key present')
else:
print('key not found')
For the dynamic key value, you can also handle through try-exception block
mydict = {'a':'apple','b':'boy','c':'cat'}
try:
print(mydict['c'])
except KeyError:
print('key value not found')mydict = {'a':'apple','b':'boy','c':'cat'}
The reason being you can not access protected member data through the instance of the class.
Reason why it is not allowed is explained in this blog
This answers improves on Rashmi Pandit's answer, which is in a way better than the rest because that it seems to completely resolve the exact problem detailed in the question.
The bad part is that is inefficient and not uses the IgnoreCase option consistently.
Inefficient part is because regex can be expensive to construct and execute, and in that answer it could have been constructed just once (calling Regex.IsMatch
was just constructing the regex again behind the scene). And Match
method could have been called only once and stored in a variable and then link
and name
should call Result
from that variable.
And the IgnoreCase option was only used in the Match
part but not in the Regex.IsMatch
part.
I also moved the Regex definition outside the method in order to construct it just once (I think is the sensible approach if we are storing that the assembly with the RegexOptions.Compiled
option).
private static Regex hrefRegex = new Regex("<td>\\s*<a\\s*href\\s*=\\s*(?:\"(?<link>[^\"]*)\"|(?<link>\\S+))\\s*>(?<name>.*)\\s*</a>\\s*</td>", RegexOptions.IgnoreCase | RegexOptions.Compiled);
public static bool TryGetHrefDetails(string htmlTd, out string link, out string name)
{
var matches = hrefRegex.Match(htmlTd);
if (matches.Success)
{
link = matches.Result("${link}");
name = matches.Result("${name}");
return true;
}
else
{
link = null;
name = null;
return false;
}
}
I solve this issue by running following command
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
hope it helps
Another approach could be to assume that your base image gets behind quite quickly (and that's very likely to happen), and force another image build of your application periodically (e.g. every week) and then re-deploy it if it has changed.
As far as I can tell, popular base images like the official Debian or Java update their tags to cater for security fixes, so tags are not immutable (if you want a stronger guarantee of that you need to use the reference [image:@digest], available in more recent Docker versions). Therefore, if you were to build your image with docker build --pull
, then your application should get the latest and greatest of the base image tag you're referencing.
Since mutable tags can be confusing, it's best to increment the version number of your application every time you do this so that at least on your side things are cleaner.
So I'm not sure that the script suggested in one of the previous answers does the job, since it doesn't rebuild you application's image - it just updates the base image tag and then it restarts the container, but the new container still references the old base image hash.
I wouldn't advocate for running cron-type jobs in containers (or any other processes, unless really necessary) as this goes against the mantra of running only one process per container (there are various arguments about why this is better, so I'm not going to go into it here).

After perusing your previous questions I eventually determined you are probably on SQL Server 2005. For US format you would use style 101

CONVERT(varchar,DeliveryDate,101) as DeliveryDate

where MerchantId =@MerchantID
Primary keys always need to be unique, foreign keys need to allow non-unique values if the table is a one-to-many relationship. It is perfectly fine to use a foreign key as the primary key if the table is connected by a one-to-one relationship, not a one-to-many relationship. If you want the same user record to have the possibility of having more than 1 related profile record, go with a separate primary key, otherwise stick with what you have.

Use row_count - your_desired_offset
So if we had 10 rows and want to offset 3
10 - 3 = 7
Now the query delete from table where this = that order asc limit 7
keeps the last 3, and order desc
to keep the first 3:
$row_count - $offset = $limit
Delete from table where entry = criteria order by ts asc limit $limit
I ended up doing the following and it works.
public static string Serialize(object obj)
{
using (MemoryStream memoryStream = new MemoryStream())
{
DataContractSerializer serializer = new DataContractSerializer(obj.GetType());
serializer.WriteObject(memoryStream, obj);
return Encoding.UTF8.GetString(memoryStream.ToArray());
}
}
public static object Deserialize(string xml, Type toType)
{
using (MemoryStream memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(xml)))
{
XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(memoryStream, Encoding.UTF8, new XmlDictionaryReaderQuotas(), null);
DataContractSerializer serializer = new DataContractSerializer(toType);
return serializer.ReadObject(reader);
}
}
It seems that the major problem was in the Serialize function when calling stream.GetBuffer(). Calling stream.ToArray() appears to work.
From python 3.6 on you can also use Literal String Interpolation, "f-strings". In your particular case the solution would be:
if re.search(rf"\b(?=\w){TEXTO}\b(?!\w)", subject, re.IGNORECASE):
...do something
EDIT:
Since there have been some questions in the comment on how to deal with special characters I'd like to extend my answer:
raw strings ('r'):
One of the main concepts you have to understand when dealing with special characters in regular expressions is to distinguish between string literals and the regular expression itself. It is very well explained here:
In short:
Let's say instead of finding a word boundary \b
after TEXTO
you want to match the string \boundary
. The you have to write:
TEXTO = "Var"
subject = r"Var\boundary"
if re.search(rf"\b(?=\w){TEXTO}\\boundary(?!\w)", subject, re.IGNORECASE):
print("match")
This only works because we are using a raw-string (the regex is preceded by 'r'), otherwise we must write "\\\\boundary" in the regex (four backslashes). Additionally, without '\r', \b' would not converted to a word boundary anymore but to a backspace!
re.escape:
Basically puts a backspace in front of any special character. Hence, if you expect a special character in TEXTO, you need to write:
if re.search(rf"\b(?=\w){re.escape(TEXTO)}\b(?!\w)", subject, re.IGNORECASE):
print("match")
NOTE: For any version >= python 3.7: !
, "
, %
, '
, ,
, /
, :
, ;
, <
, =
, >
, @
, and `
are not escaped. Only special characters with meaning in a regex are still escaped. _
is not escaped since Python 3.3.(s. here)
Curly braces:
If you want to use quantifiers within the regular expression using f-strings, you have to use double curly braces. Let's say you want to match TEXTO followed by exactly 2 digits:
if re.search(rf"\b(?=\w){re.escape(TEXTO)}\d{{2}}\b(?!\w)", subject, re.IGNORECASE):
print("match")
The key advantage is isolation. A crashing process won't bring down other processes, whereas a crashing thread will probably wreak havoc with other threads.
In my case the problem occured from php
file.
It gave unwanted characters.That is why a json parsing
problem occured.
Then I paste my php code
in Notepad++
and select Encode in utf-8 without BOM
from Encoding
tab and running this code-
My problem gone away.
It seems as of now, the only solution is still to install SublimeREPL.
To extend on Raghav's answer, it can be quite annoying to have to go into the Tools->SublimeREPL->Python->Run command every time you want to run a script with input, so I devised a quick key binding that may be handy:
To enable it, go to Preferences->Key Bindings - User, and copy this in there:
[
{"keys":["ctrl+r"] ,
"caption": "SublimeREPL: Python - RUN current file",
"command": "run_existing_window_command",
"args":
{
"id": "repl_python_run",
"file": "config/Python/Main.sublime-menu"
}
},
]
Naturally, you would just have to change the "keys" argument to change the shortcut to whatever you'd like.
As Jeffrey Said, you are not checking the value of check()
. In addition, your check()
function is not returning anything. Note the difference:
def check():
with open('example.txt') as f:
datafile = f.readlines()
found = False # This isn't really necessary
for line in datafile:
if blabla in line:
# found = True # Not necessary
return True
return False # Because you finished the search without finding
Then you can test the output of check()
:
if check():
print('True')
else:
print('False')
Try this:
return Redirect("http://www.website.com");
There are multiple false assumptions you're making here - First, function belong to a class and not to an instance, meaning the actual function involved is the same for any two instances of a class. Second, default parameters are evaluated at compile time and are constant (as in, a constant object reference - if the parameter is a mutable object you can change it). Thus you cannot access self
in a default parameter and will never be able to.

I had a similar error (connecting to MYSQL on aws via MYSql Workbench). I used to connect fine before and all of a sudden it stopped working and just wouldn't work again). My connection was via SSH protected by keyfile.
Turns out I was timing out. So I increased the SQL connection timeout to 30 secs (from default 10) and was good to go again. things to try (if you're in a similar setup)
mysql -u [username] -p [database]
? This will check for user rights issues etc.If the task you want to pass parameters to is of type JavaExec
and you are using Gradle 5, for example the application plugin's run
task, then you can pass your parameters through the --args=...
command line option. For example gradle run --args="foo --bar=true"
.
Otherwise there is no convenient builtin way to do this, but there are 3 workarounds.
If the possible values are few and are known in advance, you can programmatically create a task for each of them:
void createTask(String platform) {
String taskName = "myTask_" + platform;
task (taskName) {
... do what you want
}
}
String[] platforms = ["macosx", "linux32", "linux64"];
for(String platform : platforms) {
createTask(platform);
}
You would then call your tasks the following way:
./gradlew myTask_macosx
A convenient hack is to pass the arguments through standard input, and have your task read from it:
./gradlew myTask <<<"arg1 arg2 arg\ in\ several\ parts"
with code below:
String[] splitIntoTokens(String commandLine) {
String regex = "(([\"']).*?\\2|(?:[^\\\\ ]+\\\\\\s+)+[^\\\\ ]+|\\S+)";
Matcher matcher = Pattern.compile(regex).matcher(commandLine);
ArrayList<String> result = new ArrayList<>();
while (matcher.find()) {
result.add(matcher.group());
}
return result.toArray();
}
task taskName, {
doFirst {
String typed = new Scanner(System.in).nextLine();
String[] parsed = splitIntoTokens(typed);
println ("Arguments received: " + parsed.join(" "))
... do what you want
}
}
You will also need to add the following lines at the top of your build script:
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import java.util.Scanner;
The last option is to pass a -P
parameter to Gradle:
./gradlew myTask -PmyArg=hello
You can then access it as myArg
in your build script:
task myTask {
doFirst {
println myArg
... do what you want
}
}

Change PriorityQueue to MAX PriorityQueue Method 1 : Queue pq = new PriorityQueue<>(Collections.reverseOrder()); Method 2 : Queue pq1 = new PriorityQueue<>((a, b) -> b - a); Let's look at few Examples:
public class Example1 {
public static void main(String[] args) {
List<Integer> ints = Arrays.asList(222, 555, 666, 333, 111, 888, 777, 444);
Queue<Integer> pq = new PriorityQueue<>(Collections.reverseOrder());
pq.addAll(ints);
System.out.println("Priority Queue => " + pq);
System.out.println("Max element in the list => " + pq.peek());
System.out.println("......................");
// another way
Queue<Integer> pq1 = new PriorityQueue<>((a, b) -> b - a);
pq1.addAll(ints);
System.out.println("Priority Queue => " + pq1);
System.out.println("Max element in the list => " + pq1.peek());
/* OUTPUT
Priority Queue => [888, 444, 777, 333, 111, 555, 666, 222]
Max element in the list => 888
......................
Priority Queue => [888, 444, 777, 333, 111, 555, 666, 222]
Max element in the list => 888
*/
}
}
Let's take a famous interview Problem : Kth Largest Element in an Array using PriorityQueue
public class KthLargestElement_1{
public static void main(String[] args) {
List<Integer> ints = Arrays.asList(222, 555, 666, 333, 111, 888, 777, 444);
int k = 3;
Queue<Integer> pq = new PriorityQueue<>(Collections.reverseOrder());
pq.addAll(ints);
System.out.println("Priority Queue => " + pq);
System.out.println("Max element in the list => " + pq.peek());
while (--k > 0) {
pq.poll();
} // while
System.out.println("Third largest => " + pq.peek());
/*
Priority Queue => [888, 444, 777, 333, 111, 555, 666, 222]
Max element in the list => 888
Third largest => 666
*/
}
}
Another way :
public class KthLargestElement_2 {
public static void main(String[] args) {
List<Integer> ints = Arrays.asList(222, 555, 666, 333, 111, 888, 777, 444);
int k = 3;
Queue<Integer> pq1 = new PriorityQueue<>((a, b) -> b - a);
pq1.addAll(ints);
System.out.println("Priority Queue => " + pq1);
System.out.println("Max element in the list => " + pq1.peek());
while (--k > 0) {
pq1.poll();
} // while
System.out.println("Third largest => " + pq1.peek());
/*
Priority Queue => [888, 444, 777, 333, 111, 555, 666, 222]
Max element in the list => 888
Third largest => 666
*/
}
}
As we can see, both are giving the same result.
In Rails 3.2.18, :decimal turns into :integer when using SQLServer, but it works fine in SQLite. Switching to :float solved this issue for us.
The lesson learned is "always use homogeneous development and deployment databases!"
I had this info message "No Spring WebApplicationInitializer types detected on classpath" while deploying a WAR with spring integration beans in WebLogic server. Actually, I could observe that the servlet URL returned 404 Not Found and beside that info message with a negative tone "No Spring ...etc" in Server logs, nothing else was seemingly in error in my spring config; no build or deployment errors, no complaints. Indeed, I suspected that the beans.xml (spring context XML) was actually not picked up at all and that was bound to the very specific organizing of artefacts in Oracle's jDeveloper. The solution is to play carefully with the 'contributors' and 'filters' for the WEB-INF/classes category when you edit your deployment profile under the 'deployment' topic in project properties.
Precisely, I would advise to name your spring context by the jDeveloper default "beans.xml" and place it side by side to the WEB-INF subdirectory itself (under your web Apllication source path, e.g. like <...your project path>/public_html/). Then in the WEB-INF/classes category (when editing the deployment profile) your can check the Project HTML root directory in the 'contributor' list, and then select the beans.xml in filters, and then ensure your web.xml features a context-param value like classpath:beans.xml.
Once that was fixed, I was able to progress and after some more bean config changes and implementations, the message "No Spring WebApplicationInitializer types detected on classpath" came back! Actually, I did not notice when and why exactly it came back. This second time, I added a
public class HttpGatewayInit implements WebApplicationInitializer { ... }
which implements empty inherited methods, and the whole application works fine!
...If you feel that java EE development has been getting a bit too crazy with cascades of XML configuration files (some edited manually, others through wizards) intepreted by cascades of variant initializers, let me insist that I fully share your point.

To append to an array, just use the +=
operator.
$Target += $TargetObject
Also, you need to declare $Target = @()
before your loop because otherwise, it will empty the array every loop.

Issue Description:
One Alternative:
Simulate a class variable behavior using Objective-C features
Declare/Define an static variable within the classA.m so it will be only accessible for the classA methods (and everything you put inside classA.m).
Overwrite the NSObject initialize class method to initialize just once the static variable with an instance of ClassB.
You will be wondering, why should I overwrite the NSObject initialize method. Apple documentation about this method has the answer: "The runtime sends initialize to each class in a program exactly one time just before the class, or any class that inherits from it, is sent its first message from within the program. (Thus the method may never be invoked if the class is not used.)".
Feel free to use the static variable within any ClassA class/instance method.
Code sample:
file: classA.m
static ClassB *classVariableName = nil;
@implementation ClassA
...
+(void) initialize
{
if (! classVariableName)
classVariableName = [[ClassB alloc] init];
}
+(void) classMethodName
{
[classVariableName doSomething];
}
-(void) instanceMethodName
{
[classVariableName doSomething];
}
...
@end

In MSDN, Assembly.GetExecutingAssembly Method, is remark about method "getexecutingassembly", that for performance reasons, you should call this method only when you do not know at design time what assembly is currently executing.
The recommended way to retrieve an Assembly object that represents the current assembly is to use the Type.Assembly
property of a type found in the assembly.
The following example illustrates:
using System;
using System.Reflection;
public class Example
{
public static void Main()
{
Console.WriteLine("The version of the currently executing assembly is: {0}",
typeof(Example).Assembly.GetName().Version);
}
}
/* This example produces output similar to the following:
The version of the currently executing assembly is: 1.1.0.0
Of course this is very similar to the answer with helper class "public static class CoreAssembly", but, if you know at least one type of executing assembly, it isn't mandatory to create a helper class, and it saves your time.
So what does count_votes look like? Is it a script? Anything that you want to get back from an ajax call can be retrieved using a simple echo (of course you could use JSON or xml, but for this simple example you would just need to output something in count_votes.php like:
$id = $_POST['id'];
function getVotes($id){
// call your database here
$query = ("SELECT votes FROM poll WHERE ID = $id");
$result = @mysql_query($query);
$row = mysql_fetch_row($result);
return $row->votes;
}
$votes = getVotes($id);
echo $votes;
This is just pseudocode, but should give you the idea. What ever you echo from count_votes will be what is returned to "data" in your ajax call.
Try this :
pip install webdriver-manager
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())
In the middle of the stack trace, lost in the "reflection" junk, you can find the root cause:
The specified datastore driver ("com.mysql.jdbc.Driver") was not found in the CLASSPATH. Please check your CLASSPATH specification, and the name of the driver.
I am going to add one more answer to the pile. THis problem could happen also because of encoding. You want utf8 encoding to be on safe side. Some editors by default use utf16 which can cause issue. One quick way to test this, is, for example in VS code, simply recreate the same content but use the local editor of vscode to create the file. Hope this helps some.
On Windows they get installed to separate folders, "C:\python26" and "C:\python31", but the executables have the same "python.exe" name.
I created another "C:\python" folder that contains "python.bat" and "python3.bat" that serve as wrappers to "python26" and "python31" respectively, and added "C:\python" to the PATH
environment variable.
This allows me to type python
or python3
in my .bat Python wrappers to start the one I desire.
On Linux, you can use the #!
trick to specify which version you want a script to use.
This code may help you:
double d = double.Parse(input_value);
string output= d.ToString("F2", CultureInfo.InvariantCulture) + "%";
Don't transform to string and compare. This is not good for perfomance.
In the junit, inside Corematchers, there's a matcher for this => hasItems
List<Integer> yourList = Arrays.asList(1,2,3,4)
assertThat(yourList, CoreMatchers.hasItems(1,2,3,4,5));
This is the better way that I know of to check elements in a list.
@Cabbi raised the issue that on some systems, the microseconds format %f
may give "0"
, so it's not portable to simply chop off the last three characters.
The following code carefully formats a timestamp with milliseconds:
from datetime import datetime
(dt, micro) = datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f').split('.')
dt = "%s.%03d" % (dt, int(micro) / 1000)
print dt
Example Output:
2016-02-26 04:37:53.133
To get the exact output that the OP wanted, we have to strip punctuation characters:
from datetime import datetime
(dt, micro) = datetime.utcnow().strftime('%Y%m%d%H%M%S.%f').split('.')
dt = "%s%03d" % (dt, int(micro) / 1000)
print dt
Example Output:
20160226043839901
In postgresql you can use regular expressions in WHERE clause. Check http://www.postgresql.org/docs/8.4/static/functions-matching.html
MySQL has something simmilar: http://dev.mysql.com/doc/refman/5.5/en/regexp.html
There is really quite a number of ways to do this and all of the above are in one way or another valid approaches... Let me add a straightforward proposition. So assuming your current existing json file looks is this....
{
"name":"myname"
}
And you want to bring in this new json content (adding key "id")
{
"id": "134",
"name": "myname"
}
My approach has always been to keep the code extremely readable with easily traceable logic. So first, we read the entire existing json file into memory, assuming you are very well aware of your json's existing key(s).
import json
# first, get the absolute path to json file
PATH_TO_JSON = 'data.json' # assuming same directory (but you can work your magic here with os.)
# read existing json to memory. you do this to preserve whatever existing data.
with open(PATH_TO_JSON,'r') as jsonfile:
json_content = json.load(jsonfile) # this is now in memory! you can use it outside 'open'
Next, we use the 'with open()' syntax again, with the 'w' option. 'w' is a write mode which lets us edit and write new information to the file. Here s the catch that works for us ::: any existing json with the same target write name will be erased automatically.
So what we can do now, is simply write to the same filename with the new data
# add the id key-value pair (rmbr that it already has the "name" key value)
json_content["id"] = "134"
with open(PATH_TO_JSON,'w') as jsonfile:
json.dump(json_content, jsonfile, indent=4) # you decide the indentation level
And there you go! data.json should be good to go for an good old POST request
Error points directly that RestTemplate
bean is not defined in context and it cannot load the beans.
If you are sure that the bean is defined for the RestTemplate then use the following to print the beans that are available in the context loaded by spring boot application
ApplicationContext ctx = SpringApplication.run(Application.class, args);
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
System.out.println(beanName);
}
If this contains the bean by the name/type given, then all good. Or else define a new bean and then use it.
No, the action should be the name of php file. With on click you may only call JavaScript. And please be aware the hiding your code from the user undermines trust. JS runs on the browser so some trust is needed.
The dispatcher-servlet.xml
file contains all of your configuration for Spring MVC
. So in it you will find beans such as ViewHandlerResolvers
, ConverterFactories
, Interceptors
and so forth. All of these beans are part of Spring MVC
which is a framework that structures how you handle web requests, providing useful features such as databinding, view resolution and request mapping.
The application-context.xml
can optionally be included when using Spring MVC
or any other framework for that matter. This gives you a container that may be used to configure other types of spring beans that provide support for things like data persistence. Basically, in this configuration file is where you pull in all of the other goodies Spring offers.
These configuration files are configured in the web.xml file as shown:
Dispatcher Config
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/spring/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Application Config
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/application-context.xml</param-value>
</context-param>
<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
To configure controllers, annotate them with @Controller
then include the following in the dispatcher-context.xml
file:
<mvc:annotation-driven/>
<context:component-scan base-package="package.with.controllers.**" />
If you want to see the live preview, in the right part of the screen you should have a button call Preview that show/hide the live preview.

I use openssl, but if you prefer not to, or are on a system (particularly Windows) that doesn't have it, since java 7 in 2011 keytool
can do the whole job:
keytool -printcert -sslserver host[:port] -rfc >tempfile
keytool -import [-noprompt] -alias nm -keystore file [-storepass pw] [-storetype ty] <tempfile
# or with noprompt and storepass (so nothing on stdin besides the cert) piping works:
keytool -printcert -sslserver host[:port] -rfc | keytool -import -noprompt -alias nm -keystore file -storepass pw [-storetype ty]
Conversely, for java 9 up always, and for earlier versions in many cases, Java can use a PKCS12 file for a keystore instead of the traditional JKS file, and OpenSSL can create a PKCS12 without any assistance from keytool:
openssl s_client -connect host:port </dev/null | openssl pkcs12 -export -nokeys [-name nm] [-passout option] -out p12file
# <NUL on Windows
# default is to prompt for password, but -passout supports several options
# including actual value, envvar, or file; see the openssl(1ssl) man page

switch (name) {
case text1, text4 -> // do something ;
case text2, text3, text 5 -> // do something else ;
default -> // default case ;
}
You can also assign a value through the switch case expression :
String text = switch (name) {
case text1, text4 -> "hello" ;
case text2, text3, text5 -> "world" ;
default -> "goodbye";
};
It allows you to return a value by the switch case expression
String text = switch (name) {
case text1, text4 ->
yield "hello";
case text2, text3, text5 ->
yield "world";
default ->
yield "goodbye";
};

First of all Assert()
method is available for Trace
and Debug
classes.
Debug.Assert()
is executing only in Debug mode.
Trace.Assert()
is executing in Debug and Release mode.
Here is an example:
int i = 1 + 3;
// Debug.Assert method in Debug mode fails, since i == 4
Debug.Assert(i == 3);
Debug.WriteLine(i == 3, "i is equal to 3");
// Trace.Assert method in Release mode is not failing.
Trace.Assert(i == 4);
Trace.WriteLine(i == 4, "i is equla to 4");
Console.WriteLine("Press a key to continue...");
Console.ReadLine();
Run this code in Debug mode and then in Release mode.
You will notice that during Debug mode your code Debug.Assert
statement fails, you get a message box showing the current stack trace of the application. This is not happening in Release mode since Trace.Assert()
condition is true (i == 4)
.
WriteLine()
method simply gives you an option of logging the information to Visual Studio output.

The standard techniques to filter a list apply, although they are not as efficient as the split/join
or translate
methods.
We need a set of whitespaces:
>>> import string
>>> ws = set(string.whitespace)
The filter
builtin:
>>> "".join(filter(lambda c: c not in ws, "strip my spaces"))
'stripmyspaces'
A list comprehension (yes, use the brackets: see benchmark below):
>>> import string
>>> "".join([c for c in "strip my spaces" if c not in ws])
'stripmyspaces'
A fold:
>>> import functools
>>> "".join(functools.reduce(lambda acc, c: acc if c in ws else acc+c, "strip my spaces"))
'stripmyspaces'
Benchmark:
>>> from timeit import timeit
>>> timeit('"".join("strip my spaces".split())')
0.17734256500003198
>>> timeit('"strip my spaces".translate(ws_dict)', 'import string; ws_dict = {ord(ws):None for ws in string.whitespace}')
0.457635745999994
>>> timeit('re.sub(r"\s+", "", "strip my spaces")', 'import re')
1.017787621000025
>>> SETUP = 'import string, operator, functools, itertools; ws = set(string.whitespace)'
>>> timeit('"".join([c for c in "strip my spaces" if c not in ws])', SETUP)
0.6484303600000203
>>> timeit('"".join(c for c in "strip my spaces" if c not in ws)', SETUP)
0.950212219999969
>>> timeit('"".join(filter(lambda c: c not in ws, "strip my spaces"))', SETUP)

The existing answers already cover the "how", but I just wanted to elaborate on the "what" and "why" for others who might be wondering.
What a compiler (gcc) does: The term "compile" is a bit of an overloaded term because it is used at a high-level to mean "convert source code to a program", but more technically means to "convert source code to object code". A compiler like gcc actually performs two related, but arguably distinct functions to turn your source code into a program: compiling (as in the latter definition of turning source to object code) and linking (the process of combining the necessary object code files together into one complete executable).
The original error that you saw is technically a "linking error", and is thrown by "ld", the linker. Unlike (strict) compile-time errors, there is no reference to source code lines, as the linker is already in object space.
By default, when gcc is given source code as input, it attempts to compile each and then link them all together. As noted in the other responses, it's possible to use flags to instruct gcc to just compile first, then use the object files later to link in a separate step. This two-step process may seem unnecessary (and probably is for very small programs) but it is very important when managing a very large program, where compiling the entire project each time you make a small change would waste a considerable amount of time.
If you are using Netty and want to use a map with primitive int type keys, you can use its IntObjectHashMap
Some of the reasons to use primitive type collections:
The question of specialized vs generalized collections can make or break programs with high throughput requirements.

This guy here => http://blog.stevenlevithan.com/archives/date-time-format wrote a format()
function for the Javascript's Date
object, so it can be used with familiar literal formats.
If you need full featured Date formatting in your app's Javascript, use it. Otherwise if what you want to do is a one off, then concatenating getYear(), getMonth(), getDay() is probably easiest.
Everybody commenting seems to be coming at this from the wrong angle, it is fine to store JSON code via PHP in a relational DB and it will in fact be faster to load and display complex data like this, however you will have design considerations such as searching, indexing etc.
The best way of doing this is to use hybrid data, for example if you need to search based upon datetime MySQL (performance tuned) is going to be a lot faster than PHP and for something like searching distance of venues MySQL should also be a lot faster (notice searching not accessing). Data you do not need to search on can then be stored in JSON, BLOB or any other format you really deem necessary.
Data you need to access is very easily stored as JSON for example a basic per-case invoice system. They do not benefit very much at all from RDBMS, and could be stored in JSON just by json_encoding($_POST['entires']) if you have the correct HTML form structure.
I am glad you are happy using MongoDB and I hope that it continues to serve you well, but don't think that MySQL is always going to be off your radar, as your app increases in complexity you may well end up needing an RDBMS for some functionality and features (even if it is just for retiring archived data or business reporting)
To disable the beeps when ssh-ing in a remote machine, simply create the same ~/.inputrc

files on the remote machine to stop ssh itself from beeping.
See the answer from @Nemo for the contents of each file.
The very first actions before tunning queries is to defrag/rebuild the indexes and statistics, otherway you're wasting your time.
You must check the execution plan to see if it's stable (is the same when you change the parameters), if not, you might have to create a cover index (in this case for each table) (knowing th system you can create one that is usefull for other queries too).
as an example : create index idx01_datafeed_trans On datafeed_trans ( feedid, feedDate) INCLUDE( acctNo, tradeDate)
if the plan is stable or you can stabilize it you can execute the sentence with sp_executesql('sql sentence') to save and use a fixed execution plan.
if the plan is unstable you have to use an ad-hoc statement or EXEC('sql sentence') to evaluate and create an execution plan each time. (or a stored procedure "with recompile").
Hope it helps.
You need to change the password directly in the database because at mysql the users and their profiles are saved in the database.
So there are several ways. At phpMyAdmin you simple go to user admin, choose root and change the password.
As you're passing true as the second parameter to json_decode
, in the above example you can retrieve data doing something similar to:
<?php
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json));
var_dump(json_decode($json, true));
?>

Casting is different than converting in Java, to use informal terminology.
Casting an object means that object already is what you're casting it to, and you're just telling the compiler about it. For instance, if I have a Foo
reference that I know is a FooSubclass
instance, then (FooSubclass)Foo
tells the compiler, "don't change the instance, just know that it's actually a FooSubclass
.
On the other hand, an Integer
is not a String
, although (as you point out) there are methods for getting a String
that represents an Integer
. Since no no instance of Integer
can ever be a String
, you can't cast Integer
to String
.

Unless google serves this image with the correct Access-Control-Allow-Origin
header, then you wont be able to use their image in canvas. This is due to not having CORS
approval. You can read more about this here, but it essentially means:
Although you can use images without CORS approval in your canvas, doing so taints the canvas. Once a canvas has been tainted, you can no longer pull data back out of the canvas. For example, you can no longer use the canvas toBlob(), toDataURL(), or getImageData() methods; doing so will throw a security error.
This protects users from having private data exposed by using images to pull information from remote web sites without permission.
I suggest just passing the URL to your server-side language and using curl to download the image. Be careful to sanitise this though!
EDIT:
As this answer is still the accepted answer, you should check out @shadyshrif's answer, which is to use:
var img = new Image();
img.setAttribute('crossOrigin', 'anonymous');

This will only work if you have the correct permissions, but will at least allow you to do what you want.
I've experimented with typing "exit for" a few times and noticed it worked and VB didn't yell at me. It's an option I guess but it just looked bad.
I think the best option is similar to that shared by Tobias. Just put your code in a function and have it return when you want to break out of your loops. Looks cleaner too.
For Each item In itemlist
For Each item1 In itemlist1
If item1 = item Then
Return item1
End If
Next
Next
Just use indexer
var valueAtIndex1 = myValues[1];
I am not sure what you are trying to do. You can implement a do-while loop like this:
while True:
stuff()
if fail_condition:
break
Or:
stuff()
while not fail_condition:
stuff()
What are you doing trying to use a do while loop to print the stuff in the list? Why not just use:
for i in l:
print i
print "done"
Update:
So do you have a list of lines? And you want to keep iterating through it? How about:
for s in l:
while True:
stuff()
# use a "break" instead of s = i.next()
Does that seem like something close to what you would want? With your code example, it would be:
for s in some_list:
while True:
if state is STATE_CODE:
if "//" in s:
tokens.add( TOKEN_COMMENT, s.split( "//" )[1] )
state = STATE_COMMENT
else :
tokens.add( TOKEN_CODE, s )
if state is STATE_COMMENT:
if "//" in s:
tokens.append( TOKEN_COMMENT, s.split( "//" )[1] )
break # get next s
else:
state = STATE_CODE
# re-evaluate same line
# continues automatically
Using iReport designer 5.6.0, if you wish to compile multiple jrxml files without previewing - go to Tools -> Massive Processing Tool. Select Elaboration Type as "Compile Files", select the folder where all your jrxml reports are stored, and compile them in a batch.

Add an onblur event too.
At first I was as reluctant as @fmark to switch from optparse to argparse, because:
Then I saw this doc, argparse outperforms optparse, especially when talking about generating meaningful help message: http://argparse.googlecode.com/svn/trunk/doc/argparse-vs-optparse.html
And then I saw "argparse vs. optparse" by @Nicholas, saying we can have argparse available in python <2.7 (Yep, I didn't know that before.)
Now my two concerns are well addressed. I wrote this hoping it will help others with a similar mindset.
Try this:
import tkinter as tk
from PIL import ImageTk, Image
#This creates the main window of an application
window = tk.Tk()
window.title("Join")
window.geometry("300x300")
window.configure(background='grey')
path = "Aaron.jpg"
#Creates a Tkinter-compatible photo image, which can be used everywhere Tkinter expects an image object.
img = ImageTk.PhotoImage(Image.open(path))
#The Label widget is a standard Tkinter widget used to display a text or image on the screen.
panel = tk.Label(window, image = img)
#The Pack geometry manager packs widgets in rows or columns.
panel.pack(side = "bottom", fill = "both", expand = "yes")
#Start the GUI
window.mainloop()

For relative imports see the documentation. A relative import is when you import from a module relative to that module's location, instead of absolutely from sys.path
.
As for import *
, Python 2 allowed star imports within functions, for instance:
>>> def f():
... from math import *
... print sqrt
A warning is issued for this in Python 2 (at least recent versions). In Python 3 it is no longer allowed and you can only do star imports at the top level of a module (not inside functions or classes).
In a nutshell, this is the code which works for me :)
WebDriver driver;

jse.executeScript("arguments[0].value='"+ value +"';", element);
You need to have a smtp service setup in your local machine in order to send emails. There are many available freely just search on google.
If you own a server or VPS upload the script and it will work fine.
You could also be more restrictive in removing disallowed characters. The following regex would remove all characters that are not letters, digits or underscores:
$FileName = preg_replace('/[^\w]/', '', $UserInput);
You might want to do this to ensure maximum compatibility for filenames across different operating systems.
The output that you get after DF.to_json
is a string
. So, you can simply slice it according to your requirement and remove the commas from it too.
out = df.to_json(orient='records')[1:-1].replace('},{', '} {')
To write the output to a text file, you could do:
with open('file_name.txt', 'w') as f:
f.write(out)
This is a particularly great way to do this (you can get max of an array of objects using one of the object properties): Math.max.apply(Math,array.map(function(o){return o.y;}))
This is the accepted answer for this page: Finding the max value of an attribute in an array of objects
Query in Parado's answer is correct, if you want to use MySql too instead GETDATE() you must use (because you've tagged this question with Sql server and Mysql):

I'm not sure but aren't cookies deleted at browser close? I somehow did a never expiring cookie and chrome recognized expired date as "at browser close" ...
The sp_help built-in procedure is the SQL Server's closest thing to Oracle's DESC function IMHO
sp_help MyTable
Use
sp_help "[SchemaName].[TableName]"
or
sp_help "[InstanceName].[SchemaName].[TableName]"
in case you need to qualify the table name further
We can also use
return $this->db->count_all('table_name');
or
$this->db->from('table_name');
return $this->db->count_all_result();
or
return $this->db->count_all_result('table_name');
or
$query = $this->db->query('select * from tab');
return $query->num_rows();
Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).
You need to do a deep equals.
From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.
Object.extend(Object, {
deepEquals: function(o1, o2) {
var k1 = Object.keys(o1).sort();
var k2 = Object.keys(o2).sort();
if (k1.length != k2.length) return false;
return k1.zip(k2, function(keyPair) {
if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
} else {
return o1[keyPair[0]] == o2[keyPair[1]];
}
}).all();
}
});
Usage:
var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);
if (Object.deepEquals(anObj, anotherObj))

Have you tried something like:
textbox.text = "text" & system.environment.newline & "some more text"
It works like this:
h4 {
display:inline;
}
h4:after {
content:"\a";
white-space: pre;
}
Example: http://jsfiddle.net/Bb2d7/
The trick comes from here: https://stackoverflow.com/a/66000/509752 (to have more explanation)
You can have a look on these built-in classes :
public struct Rational
{
private long numerator;
private long denominator;
public Rational(long num = 0, long denom = 1) // This is allowed!!!
{
numerator = num;
denominator = denom;
}
}
The problem can be solved in O(n^2) by extending the 2-sum problem with minor modifications.A is the vector containing elements and B is the required sum.
int Solution::threeSumClosest(vector &A, int B) {
sort(A.begin(),A.end());
int k=0,i,j,closest,val;int diff=INT_MAX;
while(k<A.size()-2)
{
i=k+1;
j=A.size()-1;
while(i<j)
{
val=A[i]+A[j]+A[k];
if(val==B) return B;
if(abs(B-val)<diff)
{
diff=abs(B-val);
closest=val;
}
if(B>val)
++i;
if(B<val)
--j;
}
++k;
}
return closest;
For mixed position and index, use .ix
. BUT you need to make sure that your index is not of integer, otherwise it will cause confusions.
df.ix[0, 'COL_NAME'] = x
Alternatively, try
df.iloc[0, df.columns.get_loc('COL_NAME')] = x
Example:
import pandas as pd
import numpy as np
# your data
# ========================
np.random.seed(0)
df = pd.DataFrame(np.random.randn(10, 2), columns=['col1', 'col2'], index=np.random.randint(1,100,10)).sort_index()
print(df)

Embrace the future! Just to be complete, you can also do this the Python 3k way by using the print function:
from __future__ import print_function # Py 2.6+; In Py 3k not needed
mylist = ['10', 12, '14'] # Note that 12 is an int
print(*mylist,sep='\n')
Prints:
10
12
14
Eventually, print
as Python statement will go away... Might as well start to get used to it.
var handle = setInterval(changeIframe, 30000);

}
names = {'John', 'Joe', 'Steve'}
for names = 1, 3 do
print (names)
end
Try:

If you are just targeting specific domains you can try and add this in your application's Info.plist:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>example.com</key>
<dict>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<key>NSIncludesSubdomains</key>
<true/>
</dict>
</dict>
</dict>
Why don't you place the account number in a div. Style it as you please and then have a hidden input in the form that also contains the account number. Then when the form gets submitted, the value should come through and not be null.
You can change the style by wrapping the input inside a label and change the input display to none. Then, you can specify the text you want to be displayed inside a span element. Note: here I used bootstrap 4 button style (btn btn-outline-primary). You can use any style you want.
<label class="btn btn-outline-primary">
<span>Select File</span>
<input type="file">
</label>
input {
display: none;
}
The full procedure that worked for me to transfer ALL branches and tags is, combining the answers of @vikas027 and @kumarahul:
~$ git clone <url_of_old_repo>
~$ cd <name_of_old_repo>
~$ git remote add new-origin <url_of_new_repo>
~$ git push new-origin --mirror
~$ git push new-origin refs/remotes/origin/*:refs/heads/*
~$ git push new-origin --delete HEAD
The last step is because a branch named HEAD
appears in the new remote due to the wildcard
break;
.
while(choice!=99)
{
cin>>choice;
if (choice==99)
break;
cin>>gNum;
}
Here's how you would do it in Kotlin
fun <T> myMethod(item: T) where T : ClassA, T : InterfaceB {
//your code here
}
You can use Named Sections.
_Layout.cshtml
<head>
<script type="text/javascript" src="@Url.Content("/Scripts/jquery-1.6.2.min.js")"></script>
@RenderSection("JavaScript", required: false)
</head>
_SomeView.cshtml
@section JavaScript
{
<script type="text/javascript" src="@Url.Content("/Scripts/SomeScript.js")"></script>
<script type="text/javascript" src="@Url.Content("/Scripts/AnotherScript.js")"></script>
}
Let's say your table has two other columns: foo and bar
INSERT INTO Table (foo, bar, Event_ID)
SELECT foo, bar, "155"
FROM Table
WHERE Event_ID = "120"
In order to avoid this kind of ClassCastException, if you have:
class A
class B extends A
You can define a constructor in B that takes an object of A. This way we can do the "cast" e.g.:
public B(A a) {
super(a.arg1, a.arg2); //arg1 and arg2 must be, at least, protected in class A
// If B class has more attributes, then you would initilize them here
}
This limits the number of characters, but also make sure that you can paste in the field until the maximum limit.
- (void)textViewDidChange:(UITextView *)textView
{
NSString* str = [textView text];
str = [str substringToIndex:MIN(1000,[str length])];
[textView setText:str];
if([str length]==1000) {
// show some label that you've reached the limit of 1000 characters
}
}
just change your ImageView height and width to wrap_content and use
exampleImage.setScaleType(ImageView.ScaleType.FIT_XY);
in your code.
The os.makedirs
function does this. Try the following:
import os
import errno
filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
try:
os.makedirs(os.path.dirname(filename))
except OSError as exc: # Guard against race condition
if exc.errno != errno.EEXIST:
raise
with open(filename, "w") as f:
f.write("FOOBAR")
The reason to add the try-except
block is to handle the case when the directory was created between the os.path.exists
and the os.makedirs
calls, so that to protect us from race conditions.
In Python 3.2+, there is a more elegant way that avoids the race condition above:
import os
filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
f.write("FOOBAR")
Steps to generate Create table DDLs for all the tables in the Hive database and export into text file to run later:
step 1)
create a .sh
file with the below content, say hive_table_ddl.sh
#!/bin/bash
rm -f tableNames.txt
rm -f HiveTableDDL.txt
hive -e "use $1; show tables;" > tableNames.txt
wait
cat tableNames.txt |while read LINE
do
hive -e "use $1;show create table $LINE;" >>HiveTableDDL.txt
echo -e "\n" >> HiveTableDDL.txt
done
rm -f tableNames.txt
echo "Table DDL generated"
step 2)
Run the above shell script by passing 'db name' as paramanter
>bash hive_table_dd.sh <<databasename>>
output :
All the create table statements of your DB will be written into the HiveTableDDL.txt
You can perform different approaches to work around this. The best approach is, if your both buttons are suppose to do the same job, you can define a third function to do the job. for example :
private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
myJob()
}
private void ChildNode_Click(object sender, RoutedEventArgs args)
{
myJob()
}
private void myJob()
{
// Your code here
}
but if you are still persisting on doing it in your way, the best action is :
private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
}
private void ChildNode_Click(object sender, RoutedEventArgs args)
{
SubGraphButton_Click.PerformClick();
}
(And if you have no admin access to the server)
ALTER ROLE <your_login_role> SET search_path TO a,b,c;
Two important things to know about:
a, b, c
matters, as it is also the order in which the schemas will be looked up for tables. So if you have the same table name in more than one schema among the defaults, there will be no ambiguity, the server will always use the table from the first schema you specified for your search_path
.An IDE allows one to work faster and more easily... I noticed I spent a lot of time navigating in the code in a simple text editor...
In a good IDE, that time goes down if the IDE supports jumping to functions, to previous editing position,to variables... Also, a good IDE reduces the time to experiment with different language features and projects, as the start-up time can be small.
You can do so by creating an array of dtype=object
. If you try to assign a long string to a normal numpy array, it truncates the string:
>>> a = numpy.array(['apples', 'foobar', 'cowboy'])
>>> a[2] = 'bananas'
>>> a
array(['apples', 'foobar', 'banana'],
dtype='|S6')
But when you use dtype=object
, you get an array of python object references. So you can have all the behaviors of python strings:
>>> a = numpy.array(['apples', 'foobar', 'cowboy'], dtype=object)
>>> a
array([apples, foobar, cowboy], dtype=object)
>>> a[2] = 'bananas'
>>> a
array([apples, foobar, bananas], dtype=object)
Indeed, because it's an array of objects, you can assign any kind of python object to the array:
>>> a[2] = {1:2, 3:4}
>>> a
array([apples, foobar, {1: 2, 3: 4}], dtype=object)
However, this undoes a lot of the benefits of using numpy, which is so fast because it works on large contiguous blocks of raw memory. Working with python objects adds a lot of overhead. A simple example:
>>> a = numpy.array(['abba' for _ in range(10000)])
>>> b = numpy.array(['abba' for _ in range(10000)], dtype=object)
>>> %timeit a.copy()
100000 loops, best of 3: 2.51 us per loop
>>> %timeit b.copy()
10000 loops, best of 3: 48.4 us per loop
I accomplished this today by loading my SQL from a text file into one string. I then used the string Split function to separate the string into individual commands which were then sent to the server individually. Simples :)
Just realised that you need to split on \nGO just in case the letters GO appear in any of your table names etc. Guess I was lucky there!
For me maven was downloading the dependency but was unable to add it to the classpath. I saw my .classpath of the project,it didnt have any maven-related entry. When I added
<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER"/>
the issue got resolved for me.
This is how you do it in your $(document).ready()

Nowadays, code to do this should look something like:
document.getElementById('foo').addEventListener('keydown', function (event) {
if (event.keyCode == 8) {
console.log('BACKSPACE was pressed');
// Call event.preventDefault() to stop the character before the cursor
// from being deleted. Remove this line if you don't want to do that.
event.preventDefault();
}
if (event.keyCode == 46) {
console.log('DELETE was pressed');
// Call event.preventDefault() to stop the character after the cursor
// from being deleted. Remove this line if you don't want to do that.
event.preventDefault();
}
});
although in the future, once they are broadly supported in browsers, you may want to use the .key
or .code
attributes of the KeyboardEvent
instead of the deprecated .keyCode
.
Details worth knowing:
Calling event.preventDefault()
in the handler of a keydown event will prevent the default effects of the keypress. When pressing a character, this stops it from being typed into the active text field. When pressing backspace or delete in a text field, it prevents a character from being deleted. When pressing backspace without an active text field, in a browser like Chrome where backspace takes you back to the previous page, it prevents that behaviour (as long as you catch the event by adding your event listener to document
instead of a text field).
Documentation on how the value of the keyCode
attribute is determined can be found in section B.2.1 How to determine keyCode
for keydown
and keyup
events in the W3's UI Events Specification. In particular, the codes for Backspace and Delete are listed in B.2.3 Fixed virtual key codes.
There is an effort underway to deprecate the .keyCode
attribute in favour of .key
and .code
. The W3 describe the .keyCode
property as "legacy", and MDN as "deprecated".
One benefit of the change to .key
and .code
is having more powerful and programmer-friendly handling of non-ASCII keys - see the specification that lists all the possible key values, which are human-readable strings like "Backspace"
and "Delete"
and include values for everything from modifier keys specific to Japanese keyboards to obscure media keys. Another, which is highly relevant to this question, is distinguishing between the meaning of a modified keypress and the physical key that was pressed.
On small Mac keyboards, there is no Delete key, only a Backspace key. However, pressing Fn+Backspace is equivalent to pressing Delete on a normal keyboard - that is, it deletes the character after the text cursor instead of the one before it. Depending upon your use case, in code you might want to handle a press of Backspace with Fn held down as either Backspace or Delete. That's why the new key model lets you choose.
The .key
attribute gives you the meaning of the keypress, so Fn+Backspace will yield the string "Delete"
. The .code
attribute gives you the physical key, so Fn+Backspace will still yield the string "Backspace"
.
Unfortunately, as of writing this answer, they're only supported in 18% of browsers, so if you need broad compatibility you're stuck with the "legacy" .keyCode
attribute for the time being. But if you're a reader from the future, or if you're targeting a specific platform and know it supports the new interface, then you could write code that looked something like this:
document.getElementById('foo').addEventListener('keydown', function (event) {
if (event.code == 'Delete') {
console.log('The physical key pressed was the DELETE key');
}
if (event.code == 'Backspace') {
console.log('The physical key pressed was the BACKSPACE key');
}
if (event.key == 'Delete') {
console.log('The keypress meant the same as pressing DELETE');
// This can happen for one of two reasons:
// 1. The user pressed the DELETE key
// 2. The user pressed FN+BACKSPACE on a small Mac keyboard where
// FN+BACKSPACE deletes the character in front of the text cursor,
// instead of the one behind it.
}
if (event.key == 'Backspace') {
console.log('The keypress meant the same as pressing BACKSPACE');
}
});
Instead of using ->bindParam()
you can pass the data only at the time of ->execute()
:
$data = [ ':item_name' => $_POST['item_name'], ':item_type' => $_POST['item_type'], ':item_price' => $_POST['item_price'], ':item_description' => $_POST['item_description'], ':image_location' => 'images/'.$_FILES['file']['name'], ':status' => 0, ':id' => 0, ]; $stmt->execute($data);
In this way you would know exactly what values are going to be sent.
Just run this command

Today you can select elements with the same id attribute this way:
document.querySelectorAll('[id=test]');
Or this way with jQuery:
$('[id=test]');
CSS selector #test { ... }
should work also for all elements with id = "test"
. ?ut the only thing: document.querySelectorAll('#test')
(or $('#test')
) - will return only a first element with this id.
Is it good, or not - I can't tell . But sometimes it is difficult to follow unique id standart .
For example you have the comment widget, with HTML-ids, and JS-code, working with these HTML-ids. Sooner or later you'll need to render this widget many times, to comment a different objects into a single page: and here the standart will broken (often there is no time or not allow - to rewrite built-in code).

This looks for sequences of an uppercase letter followed by one or more lowercase letters. Consecutive uppercase letters will not match, as only one is allowed at a time, and it must be followed by a lowercase one.
for me encoding with utf16 worked
file = open('filename.csv', encoding="utf16")
I think you're mixing up two different paradigms here.
As you noted, the highly flexible ExternalProject
module runs its commands at build time, so you can't make direct use of Project A's import file since it's only created once Project A has been installed.
If you want to include
Project A's import file, you'll have to install Project A manually before invoking Project B's CMakeLists.txt - just like any other third-party dependency added this way or via find_file
/ find_library
/ find_package
.
If you want to make use of ExternalProject_Add
, you'll need to add something like the following to your CMakeLists.txt:
ExternalProject_Add(project_a
URL ...project_a.tar.gz
PREFIX ${CMAKE_CURRENT_BINARY_DIR}/project_a
CMAKE_ARGS -DCMAKE_INSTALL_PREFIX:PATH=<INSTALL_DIR>
)
include(${CMAKE_CURRENT_BINARY_DIR}/lib/project_a/project_a-targets.cmake)
ExternalProject_Get_Property(project_a install_dir)
include_directories(${install_dir}/include)
add_dependencies(project_b_exe project_a)
target_link_libraries(project_b_exe ${install_dir}/lib/alib.lib)

I believe they are supposed to located in C:\Windows\System32\Wer.dll and C:\Program Files\Internet Explorer\Ieshims.dll
For me leshims.dll
can be placed at C:\Windows\System32\
. Context: windows 7 64bit.
Simple way to compare time is :
$time = date('H:i:s',strtotime("11 PM"));
if($time < date('H:i:s')){
// your code
}
For me following was working:
var completionHandler:((Float)->Void)!
If you want to check on the object itself without interfering with the prototype, use hasOwnProperty()
:
var getIndexIfObjWithOwnAttr = function(array, attr, value) {
for(var i = 0; i < array.length; i++) {
if(array[i].hasOwnProperty(attr) && array[i][attr] === value) {
return i;
}
}
return -1;
}
to also include prototype attributes, use:
var getIndexIfObjWithAttr = function(array, attr, value) {
for(var i = 0; i < array.length; i++) {
if(array[i][attr] === value) {
return i;
}
}
return -1;
}
function WriteLog
{
Param ([string]$LogString)
$LogFile = "C:\$(gc env:computername).log"
$DateTime = "[{0:MM/dd/yy} {0:HH:mm:ss}]" -f (Get-Date)
$LogMessage = "$Datetime $LogString"
Add-content $LogFile -value $LogMessage
}
WriteLog "This is my log message"
You can use a spinner and set the spinnerMode to dialog, and set the layout_width and layout_height to 0, so that the main view does not show, only the dialog (dropdown view). Call performClick in the button click listener.
mButtonAdd.setOnClickListener(view -> {
spinnerAddToList.performClick();
});
Layout:
<Spinner
android:id="@+id/spinnerAddToList"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginTop="10dp"
android:prompt="@string/select_from_list"
android:theme="@style/ThemeOverlay.AppCompat.Light"
android:spinnerMode="dialog"/>
The advantage of this is you can customize your spinner any way you want.
