If the application is already open (even in background), it will be restored by "start" command. Exit the program if running then /max or /min will work
Yeah I had the same problem and it was driving me crazy because I couldn't find the image.
This may help you out...
You will then see something like this...
.ui-widget-content {
border: 1px solid #aaaaaa;
background: #ffffff url(images/ui-bg_flat_75_ffffff_40x100.png) 50% 50% repeat-x;
color: #222222;
}
And comment out the background and save the CSS document. Or you can set an absolute path to that background property and see if that works for you. (i.e. background: #ffffff url(http://.../image.png
);
Hope this helps
pypsrp - Python PowerShell Remoting Protocol Client library
At a basic level, you can use this library to;
Execute a cmd command
Run another executable
Execute PowerShell scripts
Copy a file from the localhost to the remote Windows host
Fetch a file from the remote Windows host to the localhost
Create a Runspace Pool that contains one or multiple PowerShell pipelines and execute them asynchronously
Support for a reference host base implementation of PSRP for interactive scripts
You just need to iterate the anchors in the two links.
<a href="#hide2" class="hide" id="hide2">+</a>
<a href="#show2" class="show" id="show2">-</a>
See this jsfiddle http://jsfiddle.net/eJX8z/
I also added some margin to the FAQ call to improve the format.
There is a quite interesting way to execute script minimized by making him restart itself minimised. Here is the code to put in the beginning of your script:
if not DEFINED IS_MINIMIZED set IS_MINIMIZED=1 && start "" /min "%~dpnx0" %* && exit
... script logic here ...
exit
When the script is being executed IS_MINIMIZED
is not defined (if not DEFINED IS_MINIMIZED
) so:
set IS_MINIMIZED=1
.Script starts a copy of itself using start command && start "" /min "%~dpnx0" %*
where:
""
- empty title for the window./min
- switch to run minimized."%~dpnx0"
- full path to your script.%*
- passing through all your script's parameters.Then initial script finishes its work: && exit
.
For the started copy of the script variable IS_MINIMIZED
is set by the original script so it just skips the execution of the first line and goes directly to the script logic.
exit
, otherwise the cmd window wouldn't be closed after the script execution.If your script doesn't accept arguments you could use argument as a flag instead of variable:
if "%1" == "" start "" /min "%~dpnx0" MY_FLAG && exit
or shorter
if "%1" == "" start "" /min "%~f0" MY_FLAG && exit
In order to clear all local notifications in iOS 10 apps, you should use the following code:
import UserNotifications
...
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.current()
center.removeAllPendingNotificationRequests() // To remove all pending notifications which are not delivered yet but scheduled.
center.removeAllDeliveredNotifications() // To remove all delivered notifications
} else {
UIApplication.shared.cancelAllLocalNotifications()
}
This code handles the clearing of local notifications for iOS 10.x and all preceding versions of iOS. You will need to import UserNotifications
for the iOS 10.x code.
All of the examples here (with the exception of rockacola's) require that the user physically click on the window to define focus. This isn't ideal, so .hover()
is the better choice:
$(window).hover(function(event) {
if (event.fromElement) {
console.log("inactive");
} else {
console.log("active");
}
});
This'll tell you when the user has their mouse on the screen, though it still won't tell you if it's in the foreground with the user's mouse elsewhere.
You have to use the NotifyIcon control from System.Windows.Forms, or alternatively you can use the Notify Icon API provided by Windows API. WPF Provides no such equivalent, and it has been requested on Microsoft Connect several times.
I have code on GitHub which uses System.Windows.Forms
NotifyIcon Component from within a WPF application, the code can be viewed at https://github.com/wilson0x4d/Mubox/blob/master/Mubox.QuickLaunch/AppWindow.xaml.cs
Here are the summary bits:
Create a WPF Window with ShowInTaskbar=False, and which is loaded in a non-Visible State.
At class-level:
private System.Windows.Forms.NotifyIcon notifyIcon = null;
During OnInitialize():
notifyIcon = new System.Windows.Forms.NotifyIcon();
notifyIcon.Click += new EventHandler(notifyIcon_Click);
notifyIcon.DoubleClick += new EventHandler(notifyIcon_DoubleClick);
notifyIcon.Icon = IconHandles["QuickLaunch"];
During OnLoaded():
notifyIcon.Visible = true;
And for interaction (shown as notifyIcon.Click and DoubleClick above):
void notifyIcon_Click(object sender, EventArgs e)
{
ShowQuickLaunchMenu();
}
From here you can resume the use of WPF Controls and APIs such as context menus, pop-up windows, etc.
It's that simple. You don't exactly need a WPF Window to host to the component, it's just the most convenient way to introduce one into a WPF App (as a Window is generally the default entry point defined via App.xaml), likewise, you don't need a WPF Wrapper or 3rd party control, as the SWF component is guaranteed present in any .NET Framework installation which also has WPF support since it's part of the .NET Framework (which all current and future .NET Framework versions build upon.) To date, there is no indication from Microsoft that SWF support will be dropped from the .NET Framework anytime soon.
Hope that helps.
It's a little cheese that you have to use a pre-3.0 Framework Component to get a tray-icon, but understandably as Microsoft has explained it, there is no concept of a System Tray within the scope of WPF. WPF is a presentation technology, and Notification Icons are an Operating System (not a "Presentation") concept.
notifyIcon1->ContextMenu = gcnew System::Windows::Forms::ContextMenu();
System::Windows::Forms::MenuItem^ nIItem = gcnew System::Windows::Forms::MenuItem("Open");
nIItem->Click += gcnew System::EventHandler(this, &your_class::Open_NotifyIcon);
notifyIcon1->ContextMenu->MenuItems->Add(nIItem);
I seem to have found something that worked for me which no one else mentioned.
# Ignore everything
*
# But not these files...
!.gitignore
!script.pl
!template.latex
# etc...
# And if you want to include a sub-directory and all sub-directory and files under it, but not all sub-directories
!subdir/
!subdir/**/*
Basically, it seems to negate a sub-directory from being ignored, you have to have two entries, one for the sub-directory itself !subdir/
and then another one which expands to all files and folders under it !subdir/**/*
You can use CURL for this purpose see the example code:
$url = "your url";
$content = json_encode("your data to be sent");
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);
$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
if ( $status != 201 ) {
die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " . curl_errno($curl));
}
curl_close($curl);
$response = json_decode($json_response, true);
Explain why the following code displays 2.5
instead of 3
:
$a = 012;
echo $a / 4;
Answer: When a number is preceded by a 0
in PHP, the number is treated as an octal number (base-8). Therefore the octal number 012
is equal to the decimal number 10
.
please follow the steps :
i.e : your current version is : current_version = 7.3 , and you want to change it to : new_version = 7.2
1) sudo a2dismod php(current_version)
2) sudo a2enmod php(new_version)
3) sudo update-alternatives --config php (here you need to select php version number)
4) restart apache through :
sudo /etc/init.d/apache2 restart OR
sudo service apache2 restart
I found this thread among others and I agree it contains the most complete answers so I'm adding mine too:
sed
and ed
are so useful...by hand.
Look at this code from @Johnny:
sed -i -e 's/abc/XYZ/g' /tmp/file.txt
When my restriction is to use it in a shell script, no variable can be used inside in place of "abc" or "XYZ". The BashFAQ seems to agree with what I understand at least. So, I can't use:
x='abc'
y='XYZ'
sed -i -e 's/$x/$y/g' /tmp/file.txt
#or,
sed -i -e "s/$x/$y/g" /tmp/file.txt
but, what can we do? As, @Johnny said use a while read...
but, unfortunately that's not the end of the story. The following worked well with me:
#edit user's virtual domain
result=
#if nullglob is set then, unset it temporarily
is_nullglob=$( shopt -s | egrep -i '*nullglob' )
if [[ is_nullglob ]]; then
shopt -u nullglob
fi
while IFS= read -r line; do
line="${line//'<servername>'/$server}"
line="${line//'<serveralias>'/$alias}"
line="${line//'<user>'/$user}"
line="${line//'<group>'/$group}"
result="$result""$line"'\n'
done < $tmp
echo -e $result > $tmp
#if nullglob was set then, re-enable it
if [[ is_nullglob ]]; then
shopt -s nullglob
fi
#move user's virtual domain to Apache 2 domain directory
......
As one can see if nullglob
is set then, it behaves strangely when there is a string containing a *
as in:
<VirtualHost *:80>
ServerName www.example.com
which becomes
<VirtualHost ServerName www.example.com
there is no ending angle bracket and Apache2 can't even load.
This kind of parsing should be slower than one-hit search and replace but, as you already saw, there are four variables for four different search patterns working out of one parse cycle.
The most suitable solution I can think of with the given assumptions of the problem.
If you using angular-cli Keep the json file inside Assets folder (parallel to app dir) directory
return this.http.get('<json file path inside assets folder>.json'))
.map((response: Response) => {
console.log("mock data" + response.json());
return response.json();
}
)
.catch(this.handleError);
}
Note: here you only need to give path inside assets folder like assets/json/oldjson.json then you need to write path like /json/oldjson.json
If you using webpack then you need to follow above same structure inside public folder its similar like assets folder.
Shift and integer multiply instructions have similar performance on most modern CPUs - integer multiply instructions were relatively slow back in the 1980s but in general this is no longer true. Integer multiply instructions may have higher latency, so there may still be cases where a shift is preferable. Ditto for cases where you can keep more execution units busy (although this can cut both ways).
Integer division is still relatively slow though, so using a shift instead of division by a power of 2 is still a win, and most compilers will implement this as an optimisation. Note however that for this optimisation to be valid the dividend needs to be either unsigned or must be known to be positive. For a negative dividend the shift and divide are not equivalent!
#include <stdio.h>
int main(void)
{
int i;
for (i = 5; i >= -5; --i)
{
printf("%d / 2 = %d, %d >> 1 = %d\n", i, i / 2, i, i >> 1);
}
return 0;
}
Output:
5 / 2 = 2, 5 >> 1 = 2
4 / 2 = 2, 4 >> 1 = 2
3 / 2 = 1, 3 >> 1 = 1
2 / 2 = 1, 2 >> 1 = 1
1 / 2 = 0, 1 >> 1 = 0
0 / 2 = 0, 0 >> 1 = 0
-1 / 2 = 0, -1 >> 1 = -1
-2 / 2 = -1, -2 >> 1 = -1
-3 / 2 = -1, -3 >> 1 = -2
-4 / 2 = -2, -4 >> 1 = -2
-5 / 2 = -2, -5 >> 1 = -3
So if you want to help the compiler then make sure the variable or expression in the dividend is explicitly unsigned.
For me, I was getting this error message when using PUT
or DELETE
to WebAPI. I also tried re-registering .NET Framework as suggested but to no avail.
I was able to fix this by disabling WebDAV for my individual application pool, this stopped the 'bad module' error when using PUT
or DELETE
.
WebDAV Authoring Tools
in the listDisable WebDAV
in the top right.This link is where I found the instructions but it's not very clear.
Please note that inserted, deleted
means the same thing as inserted CROSS JOIN deleted
and gives every combination of every row. I doubt this is what you want.
Something like this may help get you started...
SELECT
CASE WHEN inserted.primaryKey IS NULL THEN 'This is a delete'
WHEN deleted.primaryKey IS NULL THEN 'This is an insert'
ELSE 'This is an update'
END as Action,
*
FROM
inserted
FULL OUTER JOIN
deleted
ON inserted.primaryKey = deleted.primaryKey
Depending on what you want to do, you then reference the table you are interested in with inserted.userID
or deleted.userID
, etc.
Finally, be aware that inserted
and deleted
are tables and can (and do) contain more than one record.
If you insert 10 records at once, the inserted
table will contain ALL 10 records. The same applies to deletes and the deleted
table. And both tables in the case of an update.
EDIT Examplee Trigger after OPs edit.
ALTER TRIGGER [dbo].[UpdateUserCreditsLeft]
ON [dbo].[Order]
AFTER INSERT,UPDATE,DELETE
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from

SET NOCOUNT ON;
UPDATE

SET
CreditsLeft = CASE WHEN inserted.UserID IS NULL THEN <new value for a DELETE>
WHEN deleted.UserID IS NULL THEN <new value for an INSERT>

(
inserted
FULL OUTER JOIN
deleted
ON inserted.UserID = deleted.UserID -- This assumes UserID is the PK on UpdateUserCreditsLeft
)
ON User.UserID = COALESCE(inserted.UserID, deleted.UserID)

If the PrimaryKey of UpdateUserCreditsLeft
is something other than UserID, use that in the FULL OUTER JOIN instead.
You can use a list comprehension:
def search(name, people):
return [element for element in people if element['name'] == name]
You can use robocopy to copy files with an archive flag and reset the attribute. Use /M command line, this is my backup script with few extra tricks.
This script needs NirCmd tool to keep mouse moving so that my machine won't fall into sleep. Script is using a lockfile to tell when backup script is completed and mousemove.bat script is closed. You may leave this part out.
Another is 7-Zip tool for splitting virtualbox files smaller than 4GB files, my destination folder is still FAT32 so this is mandatory. I should use NTFS disk but haven't converted backup disks yet.

The Self-Host now uses Owin. Checkout http://www.asp.net/signalr/overview/signalr-20/getting-started-with-signalr-20/tutorial-signalr-20-self-host to setup the server. It's compatible with the client code above.
The solution you will use really depends on how long you need to wait between each execution of your function.
If you are waiting for longer than 10 minutes, I would suggest using AlarmManager
.
// Some time when you want to run
Date when = new Date(System.currentTimeMillis());
try {
Intent someIntent = new Intent(someContext, MyReceiver.class); // intent to be launched
// Note: this could be getActivity if you want to launch an activity
PendingIntent pendingIntent = PendingIntent.getBroadcast(
context,
0, // id (optional)
someIntent, // intent to launch
PendingIntent.FLAG_CANCEL_CURRENT // PendingIntent flag
);
AlarmManager alarms = (AlarmManager) context.getSystemService(
Context.ALARM_SERVICE
);
alarms.setRepeating(
AlarmManager.RTC_WAKEUP,
when.getTime(),
AlarmManager.INTERVAL_FIFTEEN_MINUTES,
pendingIntent
);
} catch(Exception e) {
e.printStackTrace();
}
Once you have broadcasted the above Intent
, you can receive your Intent
by implementing a BroadcastReceiver
. Note that this will need to be registered either in your application manifest or via the context.registerReceiver(receiver, intentFilter);
method. For more information on BroadcastReceiver
's please refer to the official documentation..
public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent)
{
System.out.println("MyReceiver: here!") // Do your work here
}
}
If you are waiting for shorter than 10 minutes then I would suggest using a Handler
.
final Handler handler = new Handler();
final int delay = 1000; // 1000 milliseconds == 1 second
handler.postDelayed(new Runnable() {
public void run() {
System.out.println("myHandler: here!"); // Do your work here
handler.postDelayed(this, delay);
}
}, delay);
I would like to add that you can have the whole data information in an object with:
const today = moment().toObject();
You should obtain an object with this properties:
today: {
date: 15,
hours: 1,
milliseconds: 927,
minutes: 59,
months: 4,
seconds: 43,
years: 2019
}
It is very useful when you have to calculate dates.
The only solution I've found is to first create the project in Android Studio, then close the project, then import the project. I searched all over and could not find the root cause and all other solutions people posted didn't work.
If I recall correctly Twig doesn't support ||
and &&
operators, but requires or
and and
to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.
{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}
Expressions
Expressions can be used in {% blocks %} and ${ expressions }.
Operator Description
== Does the left expression equal the right expression?
+ Convert both arguments into a number and add them.
- Convert both arguments into a number and substract them.
* Convert both arguments into a number and multiply them.
/ Convert both arguments into a number and divide them.
% Convert both arguments into a number and calculate the rest of the integer division.
~ Convert both arguments into a string and concatenate them.
or True if the left or the right expression is true.
and True if the left and the right expression is true.
not Negate the expression.
For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:
{% if (foo and bar) or (fizz and (foo + bar == 3)) %}
For me perfectly fork this code.
$('#dom_object_id').on('change paste keyup', function(){
console.log($("#dom_object_id").val().length)
});
Key event for .on() function is "paste" to get changes dynamically
SigSegV means a signal for memory access violation, trying to read or write from/to a memory area that your process does not have access to. These are not C or C++ exceptions and you can’t catch signals. It’s possible indeed to write a signal handler that ignores the problem and allows continued execution of your unstable program in undefined state, but it should be obvious that this is a very bad idea.
Most of the time this is because of a bug in the program. The memory address given can help debug what’s the problem (if it’s close to zero then it’s likely a null pointer dereference, if the address is something like 0xadcedfe then it’s intentional safeguard or a debug check, etc.)
One way of “catching” the signal is to run your stuff in a separate child process that can then abruptly terminate without taking your main process down with it. Finding the root cause and fixing it is obviously preferred over workarounds like this.

You can install npx
to use Angular CLI installed in your directory:
npm install -g npx
npx ng serve
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.Main_Activity);
this.setTitle("Title name");
}
To run PM2 with npm start
method and to give it a name
, run this,
pm2 start npm --name "your_app_name" -- start
To run it by passing date-format for logs,
pm2 start npm --name "your_name" --log-date-format 'DD-MM HH:mm:ss.SSS' -- start
A race condition is a situation on concurrent programming where two concurrent threads or processes compete for a resource and the resulting final state depends on who gets the resource first.
Another solution is .die() for events who that attached with .live().
Ex.:
// attach click event for <a> tags
$('a').live('click', function(){});
// deattach click event from <a> tags
$('a').die('click');
You can find a good refference here: Exploring jQuery .live() and .die()
( Sorry for my english :"> )
In addition, you can simply convert byte array
to Bitmap
.
var bmp = new Bitmap(new MemoryStream(imgByte));
You can also get Bitmap
from file Path directly.
Bitmap bmp = new Bitmap(Image.FromFile(filePath));
If you like Vim, it has built-in syntax highlighting for the syslog file, e.g. it will highlight error messages in red.
vi +'syntax on' /var/log/syslog
This can be done with an input element of a type "submit". This will appear as a button to the user and clicking the button will send the form.
<form action="" method="post">

Another source of this problem: I found that in Debian 9, the Python httplib2 is hardcoded to insist on TLS v1.0. So any application that uses httplib2 to connect to a server that insists on better security fails with TLSV1_ALERT_PROTOCOL_VERSION.
I fixed it by changing
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
to
context = ssl.SSLContext()
in /usr/lib/python3/dist-packages/httplib2/__init__.py .
Debian 10 doesn't have this problem.

Python is upset because you are attempting to assign a value to something that can't be assigned a value.
((t[1])/length) * t[1] += string
When you use an assignment operator, you assign the value of what is on the right to the variable or element on the left. In your case, there is no variable or element on the left, but instead an interpreted value: you are trying to assign a value to something that isn't a "container".
Based on what you've written, you're just misunderstanding how this operator works. Just switch your operands, like so.
string += str(((t[1])/length) * t[1])
Note that I've wrapped the assigned value in str
in order to convert it into a str
so that it is compatible with the string
variable it is being assigned to. (Numbers and strings can't be added together.)
Actually, if you want 1-1000 (inclusive), use the range(...)
function with parameters 1 and 1001: range(1, 1001)
, because the range(start, end)
function goes from start to (end-1), inclusive.
on ubuntu you can try gnome-open.
$ gnome-open http://www.google.com
System.Reflection.Assembly.GetExecutingAssembly().GetName().Name
or
typeof(Program).Assembly.GetName().Name;
I use this to check for first launch:
- (NSInteger) checkForFirstLaunch
{
NSInteger result = 0; //no first launch
// Get current version ("Bundle Version") from the default Info.plist file
NSString *currentVersion = (NSString*)[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];
NSArray *prevStartupVersions = [[NSUserDefaults standardUserDefaults] arrayForKey:@"prevStartupVersions"];
if (prevStartupVersions == nil)
{
// Starting up for first time with NO pre-existing installs (e.g., fresh
// install of some version)
[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:currentVersion] forKey:@"prevStartupVersions"];
result = 1; //first launch of the app
} else {
if (![prevStartupVersions containsObject:currentVersion])
{
// Starting up for first time with this version of the app. This
// means a different version of the app was alread installed once
// and started.
NSMutableArray *updatedPrevStartVersions = [NSMutableArray arrayWithArray:prevStartupVersions];
[updatedPrevStartVersions addObject:currentVersion];
[[NSUserDefaults standardUserDefaults] setObject:updatedPrevStartVersions forKey:@"prevStartupVersions"];
result = 2; //first launch of this version of the app
}
}
// Save changes to disk
[[NSUserDefaults standardUserDefaults] synchronize];
return result;
}
(if the user deletes the app and re-installs it, it counts like a first launch)
In the AppDelegate I check for first launch and create a navigation-controller with the login screens (login and register), which I put on top of the current main window:
[self.window makeKeyAndVisible];
if (firstLaunch == 1) {
UINavigationController *_login = [[UINavigationController alloc] initWithRootViewController:loginController];
[self.window.rootViewController presentViewController:_login animated:NO completion:nil];
}
As this is on top of the regular view controller it's independent from the rest of your app and you can just dismiss the view controller, if you don't need it anymore. And you can also present the view this way, if the user presses a button manually.
BTW: I save the login-data from my users like this:
KeychainItemWrapper *keychainItem = [[KeychainItemWrapper alloc] initWithIdentifier:@"com.youridentifier" accessGroup:nil];
[keychainItem setObject:password forKey:(__bridge id)(kSecValueData)];
[keychainItem setObject:email forKey:(__bridge id)(kSecAttrAccount)];
For the logout: I switched away from CoreData (too slow) and use NSArrays and NSDictionaries to manage my data now. Logout just means to empty those arrays and dictionaries. Plus I make sure to set my data in viewWillAppear.
That's it.
For me the error was the files under js folder not included in the project this solve my issue :
1- In the solution explorer toolbar click Show All Files.
2- open js folder and select all files under the folder
3- right click then select include In Project
4- Save and build your application then its working correct and load .css and .js files
It is possible to find where any additional SD cards are mounted by reading /proc/mounts
(standard Linux file) and cross-checking against vold data (/system/etc/vold.conf
). And note, that the location returned by Environment.getExternalStorageDirectory()
may not appear in vold configuration (in some devices it's internal storage that cannot be unmounted), but still has to be included in the list. However we didn't find a good way to describe them to the user.
You should make x
and y
numpy arrays, not lists:
x = np.array([0.46,0.59,0.68,0.99,0.39,0.31,1.09,
0.77,0.72,0.49,0.55,0.62,0.58,0.88,0.78])
y = np.array([0.315,0.383,0.452,0.650,0.279,0.215,0.727,0.512,
0.478,0.335,0.365,0.424,0.390,0.585,0.511])
With this change, it produces the expect plot. If they are lists, m * x
will not produce the result you expect, but an empty list. Note that m
is anumpy.float64
scalar, not a standard Python float
.
I actually consider this a bit dubious behavior of Numpy. In normal Python, multiplying a list with an integer just repeats the list:
In [42]: 2 * [1, 2, 3]
Out[42]: [1, 2, 3, 1, 2, 3]
while multiplying a list with a float gives an error (as I think it should):
In [43]: 1.5 * [1, 2, 3]
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-43-d710bb467cdd> in <module>()
----> 1 1.5 * [1, 2, 3]
TypeError: can't multiply sequence by non-int of type 'float'
The weird thing is that multiplying a Python list with a Numpy scalar apparently works:
In [45]: np.float64(0.5) * [1, 2, 3]
Out[45]: []
In [46]: np.float64(1.5) * [1, 2, 3]
Out[46]: [1, 2, 3]
In [47]: np.float64(2.5) * [1, 2, 3]
Out[47]: [1, 2, 3, 1, 2, 3]
So it seems that the float gets truncated to an int, after which you get the standard Python behavior of repeating the list, which is quite unexpected behavior. The best thing would have been to raise an error (so that you would have spotted the problem yourself instead of having to ask your question on Stackoverflow) or to just show the expected element-wise multiplication (in which your code would have just worked). Interestingly, addition between a list and a Numpy scalar does work:
In [69]: np.float64(0.123) + [1, 2, 3]
Out[69]: array([ 1.123, 2.123, 3.123])
I will correct usage for that method that @BullyWillPlaza suggested. Reason is that when I try to add add textArea to only contextMenu it's not visible, and if i add it to both to contextMenu and some panel it ecounters: Different parent double association if i try to switch to Design editor.
TexetObjcet.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
if (SwingUtilities.isRightMouseButton(e)){
contextmenu.add(TexetObjcet);
contextmenu.show(TexetObjcet, 0, 0);
}
}
});
Make mouse listener like this for text object you need to have popup on. What this will do is when you right click on your text object it will then add that popup and display it. This way you don't encounter that error. Solution that @BullyWillPlaza made is very good, rich and fast to implement in your program so you should try it our see how you like it.
I was getting this error due to the BasicHttpBinding not sending a compatible messageVersion to the service i was calling. My solution was to use a custom binding like below
<bindings>
<customBinding>
<binding name="Soap11UserNameOverTransport" openTimeout="00:01:00" receiveTimeout="00:1:00" >
<security authenticationMode="UserNameOverTransport">
</security>
<textMessageEncoding messageVersion="Soap11WSAddressing10" writeEncoding="utf-8" />
<httpsTransport></httpsTransport>
</binding>
</customBinding>
</bindings>
You can use the not
function rather than the :not
selector:
$(".content a").not(this).hide("slow")
If you have misused <input type="date" />
you can probably use:
$('input[type="date"]').attr('type','text');
after they have loaded to turn them into text inputs. You'll need to attach your custom datepicker first:
$('input[type="date"]').datepicker().attr('type','text');
Or you could give them a class:
$('input[type="date"]').addClass('date').attr('type','text');
You need to start the SQL Server manually. Press
windows + R
type
sqlservermanager12.msc
right click ->Start
This error might also pop-up if you run the rsync process for files that are not recently modified in the source or destination...because it cant set the time for the recently modified files.
I always do this,
f = open('filename.txt', 'a')
f.write("stuff")
f.close()
It's simple, but very useful.
I'm new comer, use python 3.8 and met the same problem. I installed with pip
instead of pip3
because i thought the pip installer is the same for python2 and python3
so this is proper installation
pip3 install flask_sqlalchemy
I didn't find find the correct jsonpath filter syntax to extract a value from a name-value pair in json.
Here's the syntax and an abbreviated sample twitter document below.
This site was useful for testing:
The jsonpath filter expression:
.events[0].attributes[?(@.name=='screen_name')].value
Test document:
{
"title" : "test twitter",
"priority" : 5,
"events" : [ {
"eventId" : "150d3939-1bc4-4bcb-8f88-6153053a2c3e",

"name" : "screen_name",
"value" : "_ziadin"
}, {
"name" : "followers_count",
"value" : "406"

There are lots of good reasons for setting the size of a frame. One is to remember the last size the user set, and restore those settings. I have this code which seems to work for me:
package javatools.swing;
import java.util.prefs.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.JFrame;
public class FramePositionMemory {
public static final String WIDTH_PREF = "-width";
public static final String HEIGHT_PREF = "-height";
public static final String XPOS_PREF = "-xpos";
public static final String YPOS_PREF = "-ypos";
String prefix;
Window frame;
Class<?> cls;
public FramePositionMemory(String prefix, Window frame, Class<?> cls) {
this.prefix = prefix;
this.frame = frame;
this.cls = cls;
}
public void loadPosition() {
Preferences prefs = (Preferences)Preferences.userNodeForPackage(cls);
// Restore the most recent mainframe size and location
int width = prefs.getInt(prefix + WIDTH_PREF, frame.getWidth());
int height = prefs.getInt(prefix + HEIGHT_PREF, frame.getHeight());
System.out.println("WID: " + width + " HEI: " + height);
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
int xpos = (screenSize.width - width) / 2;
int ypos = (screenSize.height - height) / 2;
xpos = prefs.getInt(prefix + XPOS_PREF, xpos);
ypos = prefs.getInt(prefix + YPOS_PREF, ypos);
frame.setPreferredSize(new Dimension(width, height));
frame.setLocation(xpos, ypos);
frame.pack();
}
public void storePosition() {
Preferences prefs = (Preferences)Preferences.userNodeForPackage(cls);
prefs.putInt(prefix + WIDTH_PREF, frame.getWidth());
prefs.putInt(prefix + HEIGHT_PREF, frame.getHeight());
Point loc = frame.getLocation();
prefs.putInt(prefix + XPOS_PREF, (int)loc.getX());
prefs.putInt(prefix + YPOS_PREF, (int)loc.getY());
System.out.println("STORE: " + frame.getWidth() + " " + frame.getHeight() + " " + loc.getX() + " " + loc.getY());
}
}
public class Main {
void main(String[] args) {
JFrame frame = new Frame();
// SET UP YOUR FRAME HERE.
final FramePositionMemory fm = new FramePositionMemory("scannacs2", frame, Main.class);
frame.setSize(400, 400); // default size in the absence of previous setting
fm.loadPosition();
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
Runtime.getRuntime().addShutdownHook(new Thread() {
@Override
public void run() {
fm.storePosition();
}
});
frame.setVisible(true);
}
}
}
If that's what I understood, it's like this:
C:\Users\(username)\AppData\Local\Programs\Python\Python(version)
COPY (not delete) python.exe and rename to py.exe and execute:
py filename.py
static means "associated with the class"; without it, the variable is associated with each instance of the class. If it's static, that means you'll have only one in memory; if not, you'll have one for each instance you create. static means the variable will remain in memory for as long as the class is loaded; without it, the variable can be gc'd when its instance is.
Try using another temporary pair:
pair<string,double> temp;
vector<pair<string,double>> revenue;
// Inside the loop
temp.first = "string";
temp.second = map[i].second;
revenue.push_back(temp);

You can call helper class in any controller
//view
@Html.ActionLink("Export to Excel", "Excel")
//controller Action
public void Excel()
{
var model = db.GetModel()
Export export = new Export();
export.ToExcel(Response, model);
}
//helper class
public class Export
{ public void ToExcel(HttpResponseBase Response, object clientsList)
{
var grid = new System.Web.UI.WebControls.GridView();
grid.DataSource = clientsList;
grid.DataBind();
Response.ClearContent();
Response.AddHeader("content-disposition", "attachment; filename=FileName.xls");
Response.ContentType = "application/excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
grid.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
}
}
Be careful when using the isa
function. This will be true if your object is of the specified type or one of its subclasses. You have to use strcmp
with the class
function to test if the object is specifically that type and not a subclass.
You can use PowerShell
$AttachmentPath = "CV File location"
$QueryFmt= "Query"
Invoke-Sqlcmd -ServerInstance Server -Database DBName -Query $QueryFmt | Export-CSV $AttachmentPath
The only workable solution is to restore the .bak
file. The contents and the structure of those files are not documented and therefore, there's really no way (other than an awful hack) to get this to work - definitely not worth your time and the effort!
The only tool I'm aware of that can make sense of .bak
files without restoring them is Red-Gate SQL Compare Professional (and the accompanying SQL Data Compare) which allow you to compare your database structure against the contents of a .bak
file. Red-Gate tools are absolutely marvelous - highly recommended and well worth every penny they cost!
And I just checked their web site - it does seem that you can indeed restore a single table from out of a .bak
file with SQL Compare Pro ! :-)
Extract characters from a string:
var str = "Hello world!";
var res = str.substring(1,4);
The result of res
will be:
ell
http://www.w3schools.com/jsref/jsref_substring.asp
$('.dep_buttons').mouseover(function(){
$(this).text().substring(0,25);
if($(this).text().length > 30) {
$(this).stop().animate({height:"150px"},150);
}
$(".dep_buttons").mouseout(function(){
$(this).stop().animate({height:"40px"},150);
});
});
Although there are many acceptable answers in response to this question, I don't see any examples of the sub
method using the \Datetime
object: https://www.php.net/manual/en/datetime.sub.php
So, for reference, you can also use a \DateInterval
to modify a \Datetime
object:
$date = new \DateTime('2009-01-01');
$date->sub(new \DateInterval('P1Y'));
echo $date->format('Y-m-d');
Which returns:
2008-01-01
For more information about \DateInterval
, refer to the documentation: https://www.php.net/manual/en/class.dateinterval.php
It's possible by accessing the key as index
for example:
Dictionary<string, int> dictionary = new Dictionary<string, int>();
dictionary["test"] = 1;
dictionary["test"] += 1;
Console.WriteLine (dictionary["test"]); // will print 2
Entering: /usr/bin/gcc worked for me.
Create a batch file with the following lines:
start foo.exe
start bar.exe
start baz.exe
The start command runs your command in a new window, so all 3 commands would run asynchronously.
There are few answers here indicating both strategies for 2 different versions of Jackson library below:
For Jackson 2.6.*
ObjectMapper objMapper = new ObjectMapper(new JsonFactory()); // or YAMLFactory()
objMapper.setNamingStrategy(
PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES);
For Jackson 2.7.*
ObjectMapper objMapper = new ObjectMapper(new JsonFactory()); // or YAMLFactory()
objMapper.setNamingStrategy(
PropertyNamingStrategy.SNAKE_CASE);
@jowie's solution works great. One catch, if a map has only one annotation you'll end up with a fully zoomed out map. I added 0.1 to the rect make size to make sure setVisibleMapRect has something to zoom to.
MKMapRect pointRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0.1, 0.1);
Make sure you are in the correct VirtualEnvironment. I updated PyCharm and for some reason had to point my project at my VE again. Opening the terminal, I was not in my VE when attempting zappa update (and got this error). Restarting PyCharm, all back to normal.

You could do it like this:

$(document).ready(function ()
{
$.ajax(
{
type: 'POST',
url: "/Home/MethodName",
success: function (data) {
//data is the string that the method returns in a json format, but in string
var jsonData = JSON.parse(data); //This converts the string to json
for (var i = 0; i < jsonData.length; i++) //The json object has lenght
{
var object = jsonData[i]; //You are in the current object
$('#olListId').append('<li class="someclass>' + object.Atributte + '</li>'); //now you access the property.
}
/* JSON EXAMPLE
[{ "Atributte": "value" },
{ "Atributte": "value" },
{ "Atributte": "value" }]

The main thing about this is using the property exactly the same as the attribute of the JSON key-value pair.
Simpler way (if your only keyword is "code" ) may be:
string ErrorCode = yourString.Split(new string[]{"code"}, StringSplitOptions.None).Last();
If, for example, x = 5 and is stored as string, you can also just:
x = x + 0
and the new x would be stored as a numeric value.
Use the pathlib
module.
from pathlib import Path
path = Path("/here/your/path/file.txt")
print(path.parent)
Try this:
import os.path
print os.path.abspath(os.path.join(yourpath, os.pardir))
where yourpath
is the path you want the parent for.
To animate the transition between fragments, or to animate the process of showing or hiding a fragment you use the Fragment Manager
to create a Fragment Transaction
.
Within each Fragment Transaction you can specify in and out animations that will be used for show and hide respectively (or both when replace is used).
The following code shows how you would replace a fragment by sliding out one fragment and sliding the other one in it's place.
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);
DetailsFragment newFragment = DetailsFragment.newInstance();
ft.replace(R.id.details_fragment_container, newFragment, "detailFragment");
// Start the animated transition.
ft.commit();
To achieve the same thing with hiding or showing a fragment you'd simply call ft.show
or ft.hide
, passing in the Fragment you wish to show or hide respectively.
For reference, the XML animation definitions would use the objectAnimator
tag. An example of slide_in_left might look something like this:
<?xml version="1.0" encoding="utf-8"?>
<set>
<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
android:propertyName="x"
android:valueType="floatType"
android:valueFrom="-1280"
android:valueTo="0"
android:duration="500"/>
</set>
This is a much simpler example for people only looking for removable usb drives.
using System.IO;
foreach (DriveInfo drive in DriveInfo.GetDrives())
{
if (drive.DriveType == DriveType.Removable)
{
Console.WriteLine(string.Format("({0}) {1}", drive.Name.Replace("\\",""), drive.VolumeLabel));
}
}
I think this is the simplest way for anyone else stumbling on this post given the late response:
>>> string = 'This is a string, with words!'
>>> string.split()
['This', 'is', 'a', 'string,', 'with', 'words!']
I'd like to second Stephen J. Some times X Code does just get confused. I just had an experience where I had played around with the UI a lot, and had added and deleted outlets quite a few times. The outlets just would not wire-up any more. I never did figure out a specific reason (I had tried all the solutions above), and I just had to delete the NIB and recreate it from scratch, and in fact had to use a different name for the NIB before it would work. (XCode 4.6.1) Wasted a couple of hours on that.
Here is a code sample I've used (with a .NET Core view):
@{
Microsoft.Extensions.Primitives.StringValues queryVal;
if (Context.Request.Query.TryGetValue("yourKey", out queryVal) &&
queryVal.FirstOrDefault() == "yourValue")
{
}
}
Why not just use the option Find and Replace. (every code editor has it)?
For example Visual Studio Code (under Edit option):
You just type in old name and new name and replace everyhting in the project with one click.
NOTE: This renames only file content, NOT file and folder names. Do not forget renaming folders, eg. templates/my_app_name/

Use cd

In my understanding runtime is exactly what it means - the time when the program is run. You can say something happens at runtime / run time or at compile time.
I think runtime and runtime library should be (if they aren't) two separate things. "C runtime" doesn't seem right to me. I call it "C runtime library".
Answers to your other questions: I think the term runtime can be extended to include also the environment and the context of the program when it is run, so:
This answer is to some extend just my opinion, not a fact or definition.
Use Arrays.asList()
to wrap the array in a List<String>
, which does have a contains()
method:
Arrays.asList(dan).contains(say.getText())
In case this helps anyone, I was getting this error when attempting to run aspnet_regiis.exe:
Operation failed with 0x8007000B
An attempt was made to load a program with an incorrect format
As it turns out, the server was running 2008 64 bit and I was trying to run the 32 bit version of the utility. Running the version found in \Windows\Microsoft.NET\Framework64\v2.0.50727 fixed the issue.
c:\Windows\Microsoft.NET\Framework64\v2.0.50727>aspnet_regiis.exe -i
openWindow(){
//you may choose to deduct some value from current screen size
let height = window.screen.availHeight-100;
let width = window.screen.availWidth-150;
window.open("http://your_url",`width=${width},height=${height}`);
}
If you're using express version 3.x or greater, you can use the trust proxy setting (http://expressjs.com/api.html#trust.proxy.options.table) and it will walk the chain of addresses in the x-forwarded-for header and put the latest ip in the chain that you've not configured as a trusted proxy into the ip property on the req object.
There is no notion of a function in the JDK as of java 6.
Guava has a Function interface though and the
Collections2.transform(Collection<E>, Function<E,E2>)
method provides the functionality you require.
Example:
// example, converts a collection of integers to their
// hexadecimal string representations
final Collection<Integer> input = Arrays.asList(10, 20, 30, 40, 50);
final Collection<String> output =
Collections2.transform(input, new Function<Integer, String>(){
@Override
public String apply(final Integer input){
return Integer.toHexString(input.intValue());
}
});
System.out.println(output);
Output:
[a, 14, 1e, 28, 32]
These days, with Java 8, there is actually a map function, so I'd probably write the code in a more concise way:
Collection<String> hex = input.stream()
.map(Integer::toHexString)
.collect(Collectors::toList);
You can try the free VS2010 extension: Reference Assistant by Lardite group. It works perfectly for me. This tool helps to find unused references and allows you to choose which references should be removed.
Add div wrapper
<div id=myForm>
<select name=countries>
<option value=af>Afghanistan</option>
<option value=ax>Åland Islands</option>
...
<option value=gs>South Georgia and the South Sandwich Islands</option>
...
</select>
</div>
and then write CSS
#myForm select {
width:200px; }
#myForm select:focus {
width:auto; }
Hope this will help.
I'm aware he's not asking for the inline version. But since this question has almost 100k visits and I fell here looking for that, I'll leave it here for the next fellow coder:
Make sure ESLint is not run with the --no-inline-config
flag (if this doesn't sound familiar, you're likely good to go). Then, write this in your code file (for clarity and convention, it's written on top of the file but it'll work anywhere):
/* eslint-env browser */
This tells ESLint that your working environment is a browser, so now it knows what things are available in a browser and adapts accordingly.
There are plenty of environments, and you can declare more than one at the same time, for example, in-line:
/* eslint-env browser, node */
If you are almost always using particular environments, it's best to set it in your ESLint's config file and forget about it.
From their docs:
An environment defines global variables that are predefined. The available environments are:
browser
- browser global variables.node
- Node.js global variables and Node.js scoping.commonjs
- CommonJS global variables and CommonJS scoping (use this for browser-only code that uses Browserify/WebPack).shared-node-browser
- Globals common to both Node and Browser.[...]
Besides environments, you can make it ignore anything you want. If it warns you about using console.log()
but you don't want to be warned about it, just inline:
/* eslint-disable no-console */
You can see the list of all rules, including recommended rules to have for best coding practices.
no need to that, tomcat naturally extract the war file into a folder of the same name. you simply modify the desired file inside that folder (including .xml configuration files), that's all. technically no need to restart tomcat after applying the modifications

You can try this:

simply prompts before overwriting and we can pipe n to all those questions. So this would in essence just copy non-existing files. :)
Assembly code is discussed here.
"An assembly language is a low-level language for programming computers. It implements a symbolic representation of the numeric machine codes and other constants needed to program a particular CPU architecture."
Machine code is discussed here.
"Machine code or machine language is a system of instructions and data executed directly by a computer's central processing unit."
Basically, assembler code is the language and it is translated to object code (the native code that the CPU runs) by an assembler (analogous to a compiler).
I was also developing a similar application. I was also getting not found error even though the file was there. This solve my problem. I mention my download folder in 'static_folder':
app = Flask(__name__,static_folder='pdf')
My code for the download is as follows:
@app.route('/pdf/<path:filename>', methods=['GET', 'POST'])
def download(filename):
return send_from_directory(directory='pdf', filename=filename)
This is how I am calling my file from html.
<a class="label label-primary" href=/pdf/{{ post.hashVal }}.pdf target="_blank" style="margin-right: 5px;">Download pdf </a>
<a class="label label-primary" href=/pdf/{{ post.hashVal }}.png target="_blank" style="margin-right: 5px;">Download png </a>
Even later response, but I just ran into a similar issue and ended up writing my own Image link HtmlHelper extension.
You can find an implementation of it on my blog in the link above.

I was face-off a similar situation, I need to provide to my WS: Username, Password and WSS Password Type.

Serge is right - my workaround:
function mySleep (sec)
{
SpreadsheetApp.flush();
Utilities.sleep(sec*1000);
SpreadsheetApp.flush();
}
The problem appears to be that you are reinitializing the list to an empty list in each iteration:
while choice != 0:
...
a = []
a.append(s)
Try moving the initialization above the loop so that it is executed only once.
a = []
while choice != 0:
...
a.append(s)
Referring to man page man mkdir
for option -p
-p, --parents
no error if existing, make parent directories as needed
which will create all directories in a given path, if exists throws no error otherwise it creates all directories from left to right in the given path. Try the below command. the directories newdir
and anotherdir
doesn't exists before issuing this command
Correct Usage
mkdir -p /tmp/newdir/anotherdir
After executing the command you can see newdir
and anotherdir
created under /tmp. You can issue this command as many times you want, the command always have exit(0)
. Due to this reason most people use this command in shell scripts before using those actual paths.
The reasons for warning are documented here, and the simple fixes are to turn off the warning or put the following declaration in your code to supply the version UID. The actual value is not relevant, start with 999 if you like, but changing it when you make incompatible changes to the class is.
public class HelloWorldSwing extends JFrame {
JTextArea m_resultArea = new JTextArea(6, 30);

There is a difference between hashCode() and identityHashCode() returns. It is possible that for two unequal (tested with ==) objects o1, o2 hashCode() can be the same. See the example below how this is true.
class SeeDifferences
{
public static void main(String[] args)
{
String s1 = "stackoverflow";
String s2 = new String("stackoverflow");
String s3 = "stackoverflow";
System.out.println(s1.hashCode());
System.out.println(s2.hashCode());
System.out.println(s3.hashCode());
System.out.println(System.identityHashCode(s1));
System.out.println(System.identityHashCode(s2));
System.out.println(System.identityHashCode(s3));
if (s1 == s2)
{
System.out.println("s1 and s2 equal");
}
else
{
System.out.println("s1 and s2 not equal");
}
if (s1 == s3)
{
System.out.println("s1 and s3 equal");
}
else
{
System.out.println("s1 and s3 not equal");
}
}

Using PHP, you can calculate the distance using this simple function :
// to calculate distance between two lat & lon function calculate_distance($lat1, $lon1, $lat2, $lon2, $unit='N') { $theta = $lon1 - $lon2; $dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) + cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta)); $dist = acos($dist); $dist = rad2deg($dist); $miles = $dist * 60 * 1.1515; $unit = strtoupper($unit); if ($unit == "K") { return ($miles * 1.609344); } else if ($unit == "N") { return ($miles * 0.8684); } else { return $miles; } } // function ends here
If you want to do it with multiline/multiple command/s then you can do this:

You can put in this directory your Xampp control panel shortcut
it will work fine (it will automatically start after windows startup) as @wajahat-hashmi answered above:
C:\Users\User-Name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
About aditional windows script or programs that we need to run automatically...
I needed to create some additional scripts to initialize some windows services. If someone has the same need you can put in that same directory, they will all run right after windows startup.
For me, Xampp auto start and other scripts and shortcuts worked fine in windows 8.1, I think it will work fine in any windows version.
I hope it works well for anyone who has the same need.
Also consider using Array()
. From the Ruby Community Style Guide:
Use Array() instead of explicit Array check or [*var], when dealing with a variable you want to treat as an Array, but you're not certain it's an array.
# bad
paths = [paths] unless paths.is_a? Array
paths.each { |path| do_something(path) }
# bad (always creates a new Array instance)
[*paths].each { |path| do_something(path) }
# good (and a bit more readable)
Array(paths).each { |path| do_something(path) }
Another easy way is to set the logger like this- ensure that you do it before you load the cxf web service related classes. You can use it in some static blocks.
YourClientConstructor() {
LogUtils.setLoggerClass(org.apache.cxf.common.logging.Log4jLogger.class);
URL wsdlURL = YOurURL;//
//create the service
YourService = new YourService(wsdlURL, SERVICE_NAME);
port = yourService.getServicePort();
Client client = ClientProxy.getClient(port);
client.getInInterceptors().add(new LoggingInInterceptor());
client.getOutInterceptors().add(new LoggingOutInterceptor());
}
Then the inbound and outbound messages will be printed to Log4j file instead of the console. Make sure your log4j is configured properly

Importing the namespace is somewhat cleaner. Imagine you have two different modules you import, both of them with the same method/class. Some bad stuff might happen. I'd dare say it is usually good practice to use:
import module
over
from module import function/class
If you want to change one specific onclick event with jQuery, you better use the functions .on() and .off() with a namespace (see documentation).

I just built a few TimeSpan Extension methods. Thought I could share:
public static string ToReadableAgeString(this TimeSpan span)
{
return string.Format("{0:0}", span.Days / 365.25);
}
public static string ToReadableString(this TimeSpan span)
{
string formatted = string.Format("{0}{1}{2}{3}",
span.Duration().Days > 0 ? string.Format("{0:0} day{1}, ", span.Days, span.Days == 1 ? string.Empty : "s") : string.Empty,
span.Duration().Hours > 0 ? string.Format("{0:0} hour{1}, ", span.Hours, span.Hours == 1 ? string.Empty : "s") : string.Empty,
span.Duration().Minutes > 0 ? string.Format("{0:0} minute{1}, ", span.Minutes, span.Minutes == 1 ? string.Empty : "s") : string.Empty,
span.Duration().Seconds > 0 ? string.Format("{0:0} second{1}", span.Seconds, span.Seconds == 1 ? string.Empty : "s") : string.Empty);
if (formatted.EndsWith(", ")) formatted = formatted.Substring(0, formatted.Length - 2);
if (string.IsNullOrEmpty(formatted)) formatted = "0 seconds";
return formatted;
}
Then tell read.table not to use row.names
:
systems <- read.table("http://getfile.pl?test.csv",
header=TRUE, sep=",", row.names=NULL)
and now your rows will simply be numbered.
Also look at read.csv
which is a wrapper for read.table
which already sets the sep=','
and header=TRUE
arguments so that your call simplifies to
systems <- read.csv("http://getfile.pl?test.csv", row.names=NULL)
As you know the newer versions of Spring don't use the PropertyPlaceholderConfigurer and now use another nightmarish construct called PropertySourcesPlaceholderConfigurer. If you're trying to get resolved properties from code, and wish the Spring team gave us a way to do this a long time ago, then vote this post up! ... Because this is how you do it the new way:
Subclass PropertySourcesPlaceholderConfigurer:
public class SpringPropertyExposer extends PropertySourcesPlaceholderConfigurer {
private ConfigurableListableBeanFactory factory;
/**
* Save off the bean factory so we can use it later to resolve properties
*/
@Override
protected void processProperties(ConfigurableListableBeanFactory beanFactoryToProcess,
final ConfigurablePropertyResolver propertyResolver) throws BeansException {
super.processProperties(beanFactoryToProcess, propertyResolver);
if (beanFactoryToProcess.hasEmbeddedValueResolver()) {
logger.debug("Value resolver exists.");
factory = beanFactoryToProcess;
}
else {
logger.error("No existing embedded value resolver.");
}
}
public String getProperty(String name) {
Object propertyValue = factory.resolveEmbeddedValue(this.placeholderPrefix + name + this.placeholderSuffix);
return propertyValue.toString();
}
}
To use it, make sure to use your subclass in your @Configuration and save off a reference to it for later use.
@Configuration
@ComponentScan
public class PropertiesConfig {
public static SpringPropertyExposer commonEnvConfig;
@Bean(name="commonConfig")
public static PropertySourcesPlaceholderConfigurer commonConfig() throws IOException {
commonEnvConfig = new SpringPropertyExposer(); //This is a subclass of the return type.
PropertiesFactoryBean commonConfig = new PropertiesFactoryBean();
commonConfig.setLocation(new ClassPathResource("META-INF/spring/config.properties"));
try {
commonConfig.afterPropertiesSet();
}
catch (IOException e) {
e.printStackTrace();
throw e;
}
commonEnvConfig.setProperties(commonConfig.getObject());
return commonEnvConfig;
}
}
Usage:
Object value = PropertiesConfig.commonEnvConfig.getProperty("key.subkey");
My problem was that I had a list of numbers, and I only want to replace a part of that number, soy I do this:
original_list = ['08113', '09106', '19066', '17056', '17063', '17053']
# With this part I achieve my goal
cves_mod = []
for i in range(0,len(res_list)):
cves_mod.append(res_list[i].replace(res_list[i][2:], '999'))
cves_mod
# Result
cves_mod
['08999', '09999', '19999', '17999', '17999', '17999']
If you go into the Main storyboard part, and in the bottom right go to the circle with a square, and use a blank button. Then in the code use @IBAction with it to get it wired in. Then you can make a @IBAction function with it.
This appears to be missing the providerName="System.Data.EntityClient"
bit. Sure you got the whole thing?
git clone --filter
from Git 2.19 + shallow clones
This new option might eventually become the final solution to the binary file problem, if the Git and GitHub devs and make it user friendly enough (which they arguably still haven't achieved for submodules for example).
It allows to actually only fetch files and directories that you want for the server, and was introduced together with a remote protocol extension.
With this, we could first do a shallow clone, and then automate which blobs to fetch with the build system for each type of build.
There is even already a --filter=blob:limit<size>
which allows limiting the maximum blob size to fetch.
I have provided a minimal detailed example of how the feature looks like at: How do I clone a subdirectory only of a Git repository?
Try this:
listItems = $("#productList").find("li").each(function(){
var product = $(this);
// rest of code.
});
In your oncreateView() method you need to write this code and in KEYCODE_BACk condition you can write whatever the functionality you want
View v = inflater.inflate(R.layout.xyz, container, false);
//Back pressed Logic for fragment
v.setFocusableInTouchMode(true);
v.requestFocus();
v.setOnKeyListener(new View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
getActivity().finish();
Intent intent = new Intent(getActivity(), MainActivity.class);
startActivity(intent);
return true;
}
}
return false;
}
});
You will never get your app approved by Apple if it is not developed using Xcode. Never. And if you do hack the SDK to develop on Linux and Apple finds out, don't be surprised when you are served. I am a member of the ADC and the iPhone developer program. Trust, Apple is VERY serious about this.
Don't take the risk, Buy a Macbook or Mac mini (yes a mini can run Xcode - though slowly - boost the RAM if you go with the mini). Also, while I've seen OS X hacked to run on VMware I've never seen anyone running Xcode on VM. So good luck. And I'd check the EULA before you go through the trouble.
PS: After reading the above, yes I agree If you do hack the SDK and develop on Linux at least do the final packaging on a Mac. And submit it via a Mac. Apple doesn't run through the code line by line so i doubt they'd catch that. But man, that's a lot of if's and work. Be fun to do though. :)

Go to your JDK installation. (C:\Program Files\Java\jdk1.8.0_66
for me).
Unzip the src.zip
file (becomes C:\Program Files\Java\jdk1.8.0_66\src\
for me).
In the Eclipse editor window: CTRL + Click
on a java.lang
library class. (something like String
).
Eclipse will complain Source not found
and tell you that you don't have the source.
Click Attach source
-> External Location
-> External Folder
.
Find your source folder (C:\Program Files\Java\jdk1.8.0_66\src\
for me).
Click OK
-> OK
.
Enjoy.
If you check which string would come first in a lexicon, you've done a lexicographical comparison of the strings!
Some links:
Stolen from the latter link:
A string s precedes a string t in lexicographic order if
- s is a prefix of t, or
- if c and d are respectively the first character of s and t in which s and t differ, then c precedes d in character order.
Note: For the characters that are alphabetical letters, the character order coincides with the alphabetical order. Digits precede letters, and uppercase letters precede lowercase ones.
Example:
- house precedes household
- Household precedes house
- composer precedes computer
- H2O precedes HOTEL
So, let's say you have this table:
CREATE TABLE YourTable(Col1 VARCHAR(10))
And you want to change Col1
to VARCHAR(20)
. What you need to do is this:
ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)
That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5)
, then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE
will fail.
I have a feeling that all of these "better ways to copy an array" are not really going to solve your problem.
You say
I tried a for loop like [...] but that doesn't seem to be working correctly?
Looking at that loop, there's no obvious reason for it not to work ... unless:
a
and b
arrays messed up (e.g. a
and b
refer to the same array), ora
array simultaneously.In either case, alternative ways of doing the copying won't solve the underlying problem.
The fix for the first scenario is obvious. For the second scenario you will have to figure out some way of synchronizing the threads. Atomic array classes don't help because they have no atomic copy constructors or clone methods, but synchronizing using a primitive mutex will do the trick.
(There are hints in your question that lead me to think that this is indeed thread related; e.g. your statement that a
is constantly changing.)
@Ali Shakiba your code needs some modification. Error part:
for (int i = 0; i < myArray.length; i++) {
myStatement.setString(i, myArray[i][1]);
myStatement.setString(i, myArray[i][2]);
}
Updated code:
String myArray[][] = {
{"1-1", "1-2"},
{"2-1", "2-2"},
{"3-1", "3-2"}
};
StringBuffer mySql = new StringBuffer("insert into MyTable (col1, col2) values (?, ?)");
for (int i = 0; i < myArray.length - 1; i++) {
mySql.append(", (?, ?)");
}
mysql.append(";"); //also add the terminator at the end of sql statement
myStatement = myConnection.prepareStatement(mySql.toString());
for (int i = 0; i < myArray.length; i++) {
myStatement.setString((2 * i) + 1, myArray[i][1]);
myStatement.setString((2 * i) + 2, myArray[i][2]);
}
myStatement.executeUpdate();
Create directory in the Root
sudo mkdir -p /data/db
Now change the Owner
sudo chown -R $USER /data
You're good to go!
mongod
instead of using sudo mongod

np.asscalar(a)
is deprecated since NumPy v1.16, use a.item()
instead.
For example:
a = np.array([[0.6813]])
print(a.item())
gives:
0.6813
Here is an extension method that will convert an object to a ViewDataDictionary.
public static ViewDataDictionary ToViewDataDictionary(this object values)
{
var dictionary = new ViewDataDictionary();
foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(values))
{
dictionary.Add(property.Name, property.GetValue(values));
}
return dictionary;
}
You can then use it in your view like so:
@Html.Partial("_MyPartial", new
{
Property1 = "Value1",
Property2 = "Value2"
}.ToViewDataDictionary())
Which is much nicer than the new ViewDataDictionary { { "Property1", "Value1" } , { "Property2", "Value2" }}
syntax.
Then in your partial view, you can use ViewBag
to access the properties from a dynamic object rather than indexed properties, e.g.
<p>@ViewBag.Property1</p>
<p>@ViewBag.Property2</p>
It's is mostly with missing andriod SDK. for this issue and "JAVA_HOME" error following solution worked for me... hole day saved after following steps.
To build and run apps, you need to install SDKs for each platform you wish to target. Alternatively, if you are using browser for development you can use browser platform which does not require any platform SDKs.
To check if you satisfy requirements for building the platform:
$ cordova requirements
Requirements check results for android:
Java JDK: installed .
Android SDK: installed
Android target: installed android-19,android-21,android-22,android-23,Google Inc.:Google APIs:19,Google Inc.:Google APIs (x86 System Image):19,Google Inc.:Google APIs:23
Gradle: installed
Requirements check results for ios:
Apple OS X: not installed
Cordova tooling for iOS requires Apple OS X
Error: Some of requirements check failed
When you are working with JSON data in Android, you would use JSONArray
to parse JSON which starts with the array brackets. Arrays in JSON are used to organize a collection of related items (Which could be JSON objects).
For example: [{"name":"item 1"},{"name": "item2} ]
On the other hand, you would use JSONObject
when dealing with JSON that begins with curly braces. A JSON object is typically used to contain key/value pairs related to one item.
For example: {"name": "item1", "description":"a JSON object"}
Of course, JSON arrays and objects may be nested inside one another. One common example of this is an API which returns a JSON object containing some metadata alongside an array of the items matching your query:
{"startIndex": 0, "data": [{"name":"item 1"},{"name": "item2"} ]}
C++03 3.10/1 says: "Every expression is either an lvalue or an rvalue." It's important to remember that lvalueness versus rvalueness is a property of expressions, not of objects.
Lvalues name objects that persist beyond a single expression. For example, obj
, *ptr
, ptr[index]
, and ++x
are all lvalues.
Rvalues are temporaries that evaporate at the end of the full-expression in which they live ("at the semicolon"). For example, 1729
, x + y
, std::string("meow")
, and x++
are all rvalues.
The address-of operator requires that its "operand shall be an lvalue". if we could take the address of one expression, the expression is an lvalue, otherwise it's an rvalue.
&obj; // valid
&12; //invalid

Combining @jamylak and @jpaddison3's answers together, if you need to be robust against numpy arrays as the input and handle them in the same way as lists, you should use
import numpy as np
isinstance(P, (list, tuple, np.ndarray))
This is robust against subclasses of list, tuple and numpy arrays.
And if you want to be robust against all other subclasses of sequence as well (not just list and tuple), use
import collections
import numpy as np
isinstance(P, (collections.Sequence, np.ndarray))
Why should you do things this way with isinstance
and not compare type(P)
with a target value? Here is an example, where we make and study the behaviour of NewList
, a trivial subclass of list.
>>> class NewList(list):
... isThisAList = '???'
...
>>> x = NewList([0,1])
>>> y = list([0,1])
>>> print x
[0, 1]
>>> print y
[0, 1]
>>> x==y
True
>>> type(x)
<class '__main__.NewList'>
>>> type(x) is list
False
>>> type(y) is list
True
>>> type(x).__name__
'NewList'
>>> isinstance(x, list)
True
Despite x
and y
comparing as equal, handling them by type
would result in different behaviour. However, since x
is an instance of a subclass of list
, using isinstance(x,list)
gives the desired behaviour and treats x
and y
in the same manner.
Where is this info kept ("this connection is between computer
A
and serverF
")?
A TCP connection is recognized by source IP and port and destination IP and port. Your OS, all intermediate session-aware devices and the server's OS will recognize the connection by this.
HTTP works with request-response: client connects to server, performs a request and gets a response. Without keep-alive, the connection to an HTTP server is closed after each response. With HTTP keep-alive you keep the underlying TCP connection open until certain criteria are met.
This allows for multiple request-response pairs over a single TCP connection, eliminating some of TCP's relatively slow connection startup.
When The IIS (F) sends keep alive header (or user sends keep-alive) , does it mean that (E,C,B) save a connection
No. Routers don't need to remember sessions. In fact, multiple TCP packets belonging to same TCP session need not all go through same routers - that is for TCP to manage. Routers just choose the best IP path and forward packets. Keep-alive is only for client, server and any other intermediate session-aware devices.
which is only for my session ?
Does it mean that no one else can use that connection
That is the intention of TCP connections: it is an end-to-end connection intended for only those two parties.
If so - does it mean that keep alive-header - reduce the number of overlapped connection users ?
Define "overlapped connections". See HTTP persistent connection for some advantages and disadvantages, such as:
if so , for how long does the connection is saved to me ? (in other words , if I set keep alive- "keep" till when?)
An typical keep-alive response looks like this:
Keep-Alive: timeout=15, max=100
See Hypertext Transfer Protocol (HTTP) Keep-Alive Header for example (a draft for HTTP/2 where the keep-alive header is explained in greater detail than both 2616 and 2086):
A host sets the value of the timeout
parameter to the time that the host will allows an idle connection to remain open before it is closed. A connection is idle if no data is sent or received by a host.
The max
parameter indicates the maximum number of requests that a client will make, or that a server will allow to be made on the persistent connection. Once the specified number of requests and responses have been sent, the host that included the parameter could close the connection.
However, the server is free to close the connection after an arbitrary time or number of requests (just as long as it returns the response to the current request). How this is implemented depends on your HTTP server.
max_allowed_packet
is set in mysql config, not on php side
[mysqld]
max_allowed_packet=16M
You can see it's curent value in mysql like this:
SHOW VARIABLES LIKE 'max_allowed_packet';
You can try to change it like this, but it's unlikely this will work on shared hosting:
SET GLOBAL max_allowed_packet=16777216;
You can read about it here http://dev.mysql.com/doc/refman/5.1/en/packet-too-large.html
EDIT
The [mysqld] is necessary to make the max_allowed_packet
working since at least mysql version 5.5.
Recently setup an instance on AWS EC2 with Drupal and Solr Search Engine, which required 32M max_allowed_packet
. It you set the value under [mysqld_safe]
(which is default settings came with the mysql installation) mode in /etc/my.cnf, it did no work. I did not dig into the problem. But after I change it to [mysqld]
and restarted the mysqld, it worked.
You need to append form
itself to body
too:
$form = $("<form></form>");
$form.append('<input type="button" value="button">');
$('body').append($form);
WINDOWS
(Alt+F12 or View->Tool Windows->Terminal).
Then type "move file_path/google-services.json app/"

scp '/home/developer/Desktop/google-services.json' 'app/'
After "AND" and after "OR" the QUERY has forgotten what it is all about.

As of Node.js v6.0.0 using the constructor method has been deprecated and the following method should instead be used to construct a new buffer from a base64 encoded string:
var b64string = /* whatever */;
var buf = Buffer.from(b64string, 'base64'); // Ta-da
For Node.js v5.11.1 and below
Construct a new Buffer
and pass 'base64'
as the second argument:
var b64string = /* whatever */;
var buf = new Buffer(b64string, 'base64'); // Ta-da
If you want to be clean, you can check whether from
exists :
if (typeof Buffer.from === "function") {
// Node 5.10+
buf = Buffer.from(b64string, 'base64'); // Ta-da
} else {
// older Node versions, now deprecated
buf = new Buffer(b64string, 'base64'); // Ta-da
}
I once worked on a machine where 0 was a valid address and NULL was defined as a special octal value. On that machine (0 != NULL), so code such as
char *p;
...
if (p) { ... }
would not work as you expect. You HAD to write
if (p != NULL) { ... }
Although I believe most compilers define NULL as 0 these days I still remember the lesson from those years ago: NULL is not necessarily 0.
If the src is already set then the event is firing in the cached case before you even get the event handler bound. So, you should trigger the event based off .complete
also.
code sample:
$("img").one("load", function() {
//do stuff
}).each(function() {
if(this.complete || /*for IE 10-*/ $(this).height() > 0)
$(this).load();
});
For me.
Edit .gitattributes file.
add
*.dll binary
Then everything goes well.
If you want to use hex codes, you should add -e
option to enable interpretation of backslash escapes by echo (but the result is the same as with echo
CtrlRCtrlB). And as wallyk said, you probably want to add -n
to prevent the output of a newline:
echo -en '\x12\x02' > /dev/ttyS0
Also make sure that /dev/ttyS0
is the port you want.
To differentiate between scroll up/down in jQuery, you could use:
var mousewheelevt = (/Firefox/i.test(navigator.userAgent)) ? "DOMMouseScroll" : "mousewheel" //FF doesn't recognize mousewheel as of FF3.x
$('#yourDiv').bind(mousewheelevt, function(e){
var evt = window.event || e //equalize event object
evt = evt.originalEvent ? evt.originalEvent : evt; //convert to originalEvent if possible
var delta = evt.detail ? evt.detail*(-40) : evt.wheelDelta //check for detail first, because it is used by Opera and FF
if(delta > 0) {
//scroll up
}
else{
//scroll down
}
});
This method also works in divs that have overflow:hidden
.
I successfully tested it in FireFox, IE and Chrome.
Just write an extension method to help you out:
public static class Extensions
{
public static void ForEachWithNull<T>(this IEnumerable<T> source, Action<T> action)
{
if(source == null)
{
return;
}
foreach(var item in source)
{
action(item);
}
}
}
Had gulp command not found problem in windows 10 and Adding "%AppData%\npm\node_modules" doesn't work for me. Do this steps please:
After doing
npm install -g npm
And
npm install -g gulp
Add
C:\Users\YourUsername\npm
to Path in System Variables.
It Works for me after all solutions failed me.
There is a jQuery solution in this thread. Try something like this:
var decoded = $("<div/>").html('your string').text();
This sets the innerHTML of a new <div>
element (not appended to the page), causing jQuery to decode it into HTML, which is then pulled back out with .text()
.
While respond_to?

I'm learning Algorithm right now, so i wonder how bisect module writes. Here is the code from bisect module about inserting an item into sorted list, which uses dichotomy:
def insort_right(a, x, lo=0, hi=None):
"""Insert item x in list a, and keep it sorted assuming a is sorted.
If x is already in a, insert it to the right of the rightmost x.
Optional args lo (default 0) and hi (default len(a)) bound the

"""
if lo < 0:
raise ValueError('lo must be non-negative')
if hi is None:
hi = len(a)
while lo < hi:
mid = (lo+hi)//2
if x < a[mid]:
hi = mid
else:
lo = mid+1
a.insert(lo, x)

This is such a common problem, especially in GUI applications, that I'm surprised there isn't a BCL class to do this out of the box. Here's how I do it.
public static class ReflectiveEnumerator
{
static ReflectiveEnumerator() { }
public static IEnumerable<T> GetEnumerableOfType<T>(params object[] constructorArgs) where T : class, IComparable<T>
{
List<T> objects = new List<T>();
foreach (Type type in
Assembly.GetAssembly(typeof(T)).GetTypes()
.Where(myType => myType.IsClass && !myType.IsAbstract && myType.IsSubclassOf(typeof(T))))
{
objects.Add((T)Activator.CreateInstance(type, constructorArgs));
}
objects.Sort();
return objects;
}
}
A few notes:
Assembly.GetAssembly(typeof(T))
because your base class might be in a different assembly. type.IsClass
and !type.IsAbstract
because it'll throw an exception if you try to instantiate an interface or abstract class.IComparable
so that they can be sorted.You are using improper syntax. If you read the docs mysqli_query() you will find that it needs two parameter.
mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )
mysql $link
generally means, the resource object of the established mysqli connection to query the database.
So there are two ways of solving this problem
mysqli_query();
$myConnection= mysqli_connect("$db_host","$db_username","$db_pass", "mrmagicadam") or die ("could not connect to mysql");
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysqli_query($myConnection, $sqlCommand) or die(mysqli_error($myConnection));
Or, Using mysql_query()
(This is now obselete)
$myConnection= mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("mrmagicadam") or die ("no database");
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysql_query($sqlCommand) or die(mysql_error());
As pointed out in the comments, be aware of using die to just get the error. It might inadvertently give the viewer some sensitive information .
If you create a web based application, the better solution is to check the directory exists or not then create the file if not exist. If exists, recreate again.
private File createFile(String path, String fileName) throws IOException {
ClassLoader classLoader = getClass().getClassLoader();
File file = new File(classLoader.getResource(".").getFile() + path + fileName);
// Lets create the directory
try {
file.getParentFile().mkdir();
} catch (Exception err){
System.out.println("ERROR (Directory Create)" + err.getMessage());
}
// Lets create the file if we have credential
try {
file.createNewFile();
} catch (Exception err){
System.out.println("ERROR (File Create)" + err.getMessage());
}
return file;
}

$code = $res->getStatusCode();
$result = $res->json();

I had a similar issue while working with Jupyter. I was trying to copy files from one directory to another using copy function of shutil. The problem was that I had forgotten to import the package.(Silly) But instead of python giving import error, it gave this error.
Solved by adding:
from shutil import copy
How about a dict comprehension:
filtered_dict = {k:v for k,v in d.iteritems() if filter_string in k}
One you see it, it should be self-explanatory, as it reads like English pretty well.
This syntax requires Python 2.7 or greater.
In Python 3, there is only dict.items()
, not iteritems()
so you would use:
filtered_dict = {k:v for (k,v) in d.items() if filter_string in k}

Shift + Control + I opens the Developer tool window. From bottom-left second image (that looks like the following) will open/hide the console for you:
autocomplete="off"
works now, so you can just do the following:
<input id="firstName2" name="firstName2" autocomplete="off">
Tested in the current Chrome 70 as well as in all versions starting from Chrome 62.
Demo:
input
has the auto complete workinginput
has the auto complete disabled by adding autocomplete="off"
There several answers here that don't handle simple edge cases like negative step, wrong start, stop etc. Here's the version that handles many of these cases correctly giving same behaviour as native range()
:
def frange(start, stop=None, step=1):
if stop is None:
start, stop = 0, start
steps = int((stop-start)/step)
for i in range(steps):
yield start
start += step
Note that this would error out step=0 just like native range
. One difference is that native range returns object that is indexable and reversible while above doesn't.
You can play with this code and test cases here.
Just searched for the docs, and found this:
Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:
{# returns true #}
{{ 1 in [1, 2, 3] }}
{{ 'cd' in 'abcde' }}
If you have a list of columns you want to concatenate and maybe you'd like to use some separator, here's what you can do
def concat_columns(df, cols_to_concat, new_col_name, sep=" "):
df[new_col_name] = df[cols_to_concat[0]]
for col in cols_to_concat[1:]:
df[new_col_name] = df[new_col_name].astype(str) + sep + df[col].astype(str)
This should be faster than apply
and takes an arbitrary number of columns to concatenate.
As mentioned, DCOMP is part of the VC++ redistributables (implementing the OpenMP runtime) and is the only truly missing component. All the rest are false reports.
Specifically API-MS-WIN-XXXX.DLL are API-sets - essentially, an extra level of call indirection introduced gradually since Windows 7. Dependency Walker development seemingly halted long before that, and it can't handle API sets properly.
So there is nothing to worry about there. You're not missing anything more.
A better alternative to find the truly needed DLL files that are missing (if that is indeed the problem) is to run Process Monitor and step backwards from the failure, searching for sequences of failed probes for a specific DLL file in all the system path.

Word Boundary: \b*
The word boundary \b matches positions where one side is a word character (usually a letter, digit or underscore—but see below for variations across engines) and the other side is not a word character (for instance, it may be the beginning of the string or a space character).
The regex \bcat\b would, therefore, match cat in a black cat, but it wouldn't match it in catatonic, tomcat or certificate. Removing one of the boundaries, \bcat would match cat in catfish, and cat\b would match cat in tomcat, but not vice-versa. Both, of course, would match cat on its own.
Not-a-word-boundary: \B
\B matches all positions where \b doesn't match. Therefore, it matches:
? When neither side is a word character, for instance at any position in the string $=(@-%++) (including the beginning and end of the string)
? When both sides are a word character, for instance between the H and the i in Hi!
This may not seem very useful, but sometimes \B is just what you want. For instance,
? \Bcat\B will find cat fully surrounded by word characters, as in certificate, but neither on its own nor at the beginning or end of words.
? cat\B will find cat both in certificate and catfish, but neither in tomcat nor on its own.
? \Bcat will find cat both in certificate and tomcat, but neither in catfish nor on its own.
? \Bcat|cat\B will find cat in embedded situation, e.g. in certificate, catfish or tomcat, but not on its own.
LINQ is the canonical example (for example, talking to a database), but in truth, any time you care more about expressing what to do, rather than actually doing it. For example, I use this approach in the RPC stack of protobuf-net (to avoid code-generation etc) - so you call a method with:
string result = client.Invoke(svc => svc.SomeMethod(arg1, arg2, ...));
This deconstructs the expression tree to resolve SomeMethod
(and the value of each argument), performs the RPC call, updates any ref
/out
args, and returns the result from the remote call. This is only possible via the expression tree. I cover this more here.
Another example is when you are building the expression trees manually for the purpose of compiling to a lambda, as done by the generic operators code.
Your Approach is fine, but you can add UIActionSheet
with other way with ease.
You can add UIActionSheetDelegate
in UIViewController` like
class ViewController: UIViewController ,UIActionSheetDelegate
Set you method like,
@IBAction func downloadSheet(sender: AnyObject)
{
let actionSheet = UIActionSheet(title: "Choose Option", delegate: self, cancelButtonTitle: "Cancel", destructiveButtonTitle: nil, otherButtonTitles: "Save", "Delete")
actionSheet.showInView(self.view)
}
You can get your button index when it clicked like
func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex buttonIndex: Int)
{
println("\(buttonIndex)")
switch (buttonIndex){
case 0:
println("Cancel")
case 1:
println("Save")
case 2:
println("Delete")
default:
println("Default")
//Some code here..
}
}
Update 1: for iOS8+
//Create the AlertController and add Its action like button in Actionsheet
let actionSheetControllerIOS8: UIAlertController = UIAlertController(title: "Please select", message: "Option to select", preferredStyle: .ActionSheet)
let cancelActionButton = UIAlertAction(title: "Cancel", style: .cancel) { _ in
print("Cancel")
}
actionSheetControllerIOS8.addAction(cancelActionButton)
let saveActionButton = UIAlertAction(title: "Save", style: .default)
{ _ in
print("Save")
}
actionSheetControllerIOS8.addAction(saveActionButton)
let deleteActionButton = UIAlertAction(title: "Delete", style: .default)
{ _ in
print("Delete")
}
actionSheetControllerIOS8.addAction(deleteActionButton)
self.present(actionSheetControllerIOS8, animated: true, completion: nil)
There is no rule. I find CTEs more readable, and use them unless they exhibit some performance problem, in which case I investigate the actual problem rather than guess that the CTE is the problem and try to re-write it using a different approach. There is usually more to the issue than the way I chose to declaratively state my intentions with the query.
There are certainly cases when you can unravel CTEs or remove subqueries and replace them with a #temp table and reduce duration. This can be due to various things, such as stale stats, the inability to even get accurate stats (e.g. joining to a table-valued function), parallelism, or even the inability to generate an optimal plan because of the complexity of the query (in which case breaking it up may give the optimizer a fighting chance). But there are also cases where the I/O involved with creating a #temp table can outweigh the other performance aspects that may make a particular plan shape using a CTE less attractive.
Quite honestly, there are way too many variables to provide a "correct" answer to your question. There is no predictable way to know when a query may tip in favor of one approach or another - just know that, in theory, the same semantics for a CTE or a single subquery should execute the exact same. I think your question would be more valuable if you present some cases where this is not true - it may be that you have discovered a limitation in the optimizer (or discovered a known one), or it may be that your queries are not semantically equivalent or that one contains an element that thwarts optimization.
So I would suggest writing the query in a way that seems most natural to you, and only deviate when you discover an actual performance problem the optimizer is having. Personally I rank them CTE, then subquery, with #temp table being a last resort.
In order to keep both versions, I just changed the value of PATH environment variable by putting the new version's git path "/usr/local/git/bin/" at the beginning, it forces to use the newest version:
$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin/
$ git --version
git version 2.4.9 (Apple Git-60)
original value: /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin/
new value: /usr/local/git/bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin
$ export PATH=/usr/local/git/bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin
$ git --version
git version 2.13.0
Coming out of nowhere to this question, but i think .bind
will do the trick. Find the sample code below.
const handleClick = (data) => {
console.log(data)
}
<button onClick={handleClick.bind(null, { title: 'mytitle', id: '12345' })}>Login</button>
Try this, but I don't think it will work because you're not supposed to be able to change this
Put this line in an htaccess file in the directory you want the setting to be enabled:
php_value allow_url_fopen On
Note that this setting will only apply to PHP file's in the same directory as the htaccess file.
As an alternative to using url_fopen, try using curl.
It is not clear what you mean by auto-generate a guid into an insert statement but at a guess, I think you are trying to do something like the following:
INSERT INTO MY_TAB (ID, NAME) VALUES (SYS_GUID(), 'Adams');
INSERT INTO MY_TAB (ID, NAME) VALUES (SYS_GUID(), 'Baker');
In that case I believe the ID column should be declared as RAW(16);
I am doing this off the top of my head. I don't have an Oracle instance handy to test against, but I think that is what you want.
If if doesn't work then use "!Important"
@media (min-width: 1200px) { .container { width: 970px !important; } }
Check Window > Preferences > Java > Installed JREs. Make sure there's something there; if there isn't, add one.
Did you recently update your JDK?
function getKeys(obj){
var keys = [];
for (key in obj) {
if (obj.hasOwnProperty(key)) { keys[keys.length] = key; }
}
return keys;
}
when you perform a test, you ever have the probabilty to reject the null hypothesis when it is true.
See the nextt R code:
p=function(n){
x=rnorm(n,0,1)
s=shapiro.test(x)
s$p.value
}
rep1=replicate(1000,p(5))
rep2=replicate(1000,p(100))
plot(density(rep1))
lines(density(rep2),col="blue")
abline(v=0.05,lty=3)
The graph shows that whether you have a sample size small or big a 5% of the times you have a chance to reject the null hypothesis when it s true (a Type-I error)
The idea of non-blocking is that the loop iterations are quick. So to iterate for each tick should take short enough a time that the setTimeout will be accurate to within reasonable precision (off by maybe <100 ms or so).
In theory though you're right. If I write an application and block the tick, then setTimeouts will be delayed. So to answer you're question, who can assure setTimeouts execute on time? You, by writing non-blocking code, can control the degree of accuracy up to almost any reasonable degree of accuracy.
As long as javascript is "single-threaded" in terms of code execution (excluding web-workers and the like), that will always happen. The single-threaded nature is a huge simplification in most cases, but requires the non-blocking idiom to be successful.
Try this code out either in your browser or in node, and you'll see that there is no guarantee of accuracy, on the contrary, the setTimeout will be very late:
var start = Date.now();
// expecting something close to 500
setTimeout(function(){ console.log(Date.now() - start); }, 500);
// fiddle with the number of iterations depending on how quick your machine is
for(var i=0; i<5000000; ++i){}
Unless the interpreter optimises the loop away (which it doesn't on chrome), you'll get something in the thousands. Remove the loop and you'll see it's 500 on the nose...

I am not sure is it the right way but this one works for me.
First import the component which contains the method you want to call in your component
import myComponent from './MyComponent'
and then call any method of MyCompenent
myComponent.methods.doSomething()
I had some what similar requirement - to find first day of the month
but based on year end month
selected by user in their profile page.
Problem statement - find all the txns
done by the user in his/her financial year. Financial year
is determined using year end
month value where month
can be any valid month - 1 for Jan
, 2 for Feb
, 3 for Mar
,....12 for Dec
.
For some clients financial year end
s on March
and some observe it on December
.
Scenarios - (Today is `08 Aug, 2018`)
1. If `financial year` ends on `July` then query should return `01 Aug 2018`.
2. If `financial year` ends on `December` then query should return `01 January 2018`.
3. If `financial year` ends on `March` then query should return `01 April 2018`.
4. If `financial year` ends on `September` then query should return `01 October 2017`.
And, finally below is the query. -
select @date := (case when ? >= month(now())
then date_format((subdate(subdate(now(), interval (12 - ? + month(now()) - 1) month), interval day(now()) - 2 day)) ,'%Y-%m-01')
else date_format((subdate(now(), interval month(now()) - ? - 1 month)), '%Y-%m-01') end)
where ?
is year end
month (values from 1 to 12).
Here is a more complete example using a fieldset
for accessibility reasons and specifying the first button as the default. Without a fieldset
, what the radio buttons are for as a whole can not be programmatically determined.
Model
public class MyModel
{
public bool IsMarried { get; set; }
}
View
<fieldset>
<legend>Married</legend>
@Html.RadioButtonFor(e => e.IsMarried, true, new { id = "married-true" })
@Html.Label("married-true", "Yes")
@Html.RadioButtonFor(e => e.IsMarried, false, new { id = "married-false" })
@Html.Label("married-false", "No")
</fieldset>
You can add a @checked
argument to the anonymous object to set the radio button as the default:
new { id = "married-true", @checked = 'checked' }
Note that you can bind to a string by replacing true
and false
with the string values.
If you want to feel especially sly, you can write it as this:
(firstWord, rest) = yourLine.split(maxsplit=1)
This is supposed to bring the best from both worlds:
maxsplit
while splitting with any whitespaceI kind of fell in love with this solution and it's general unpacking capability, so I had to share it.
For usages of Write-Host
, PSScriptAnalyzer
produces the following diagnostic:
Avoid using
Write-Host
because it might not work in all hosts, does not work when there is no host, and (prior to PS 5.0) cannot be suppressed, captured, or redirected. Instead, useWrite-Output
,Write-Verbose
, orWrite-Information
.
See the documentation behind that rule for more information. Excerpts for posterity:
The use of
Write-Host
is greatly discouraged unless in the use of commands with theShow
verb. TheShow
verb explicitly means "show on the screen, with no other possibilities".Commands with the
Show
verb do not have this check applied.
Jeffrey Snover has a blog post Write-Host Considered Harmful in which he claims Write-Host is almost always the wrong thing to do because it interferes with automation and provides more explanation behind the diagnostic, however the above is a good summary.
How about using XQuery with a one liner:
DECLARE @MalformedXML xml, @StrippedText varchar(max)
SET @MalformedXML = @xml.query('for $x in //. return ($x)//text()')
SET @StrippedText = CAST(@MalformedXML as varchar(max))
This loops through all elements and returns the text() only.
To avoid text between elements concatenating without spaces, use:
DECLARE @MalformedXML xml, @StrippedText varchar(max)
SET @MalformedXML = @xml.query('for $x in //. return concat((($x)//text())[1]," ")')
SET @StrippedText = CAST(@MalformedXML as varchar(max))
And to respond to "How do you use this for a column:
SELECT CAST(html_column.query('for $x in //. return concat((($x)//text()) as varchar(max))
FROM table
For the above code, ensure your html_column
is of data type xml
, if not, you need to save a casted version of the html as xml
. I would do this as a separate exercise when you are loading HTML data, as SQL will throw an error if it finds malformed xml, e.g. mismatched start/end tags, invalid characters.
These are excellent for when you want to build seachh phrases, strip HTML, etc.
Just note that this returns type xml, so CAST or COVERT to text where appropriate. The xml version of this data type is useless, as it is not a well formed XML.
You're missing semi-colons after your javascript lines. Also, window.location
should have .href
or .replace
etc to redirect - See this post for more information.
echo '<script type="text/javascript">';
echo 'alert("review your answer");';
echo 'window.location.href = "index.php";';
echo '</script>';
For clarity, try leaving PHP tags for this:
?>
<script type="text/javascript">
alert("review your answer");
window.location.href = "index.php";
</script>
<?php
NOTE: semi colons on seperate lines are optional, but encouraged - however as in the comments below, PHP won't break lines in the first example here but will in the second, so semi-colons are required in the first example.
This hasn't solved my problem too, so I changed the parameters slightly.
This code worked for me:
var dataValue = "{ name: 'person', isGoing: 'true', returnAddress: 'returnEmail' }";
$.ajax({
type: "POST",
url: "Default.aspx/OnSubmit",
data: dataValue,
contentType: 'application/json; charset=utf-8',
dataType: 'json',
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
},
success: function (result) {
alert("We returned: " + result.d);
}
});
A Unix tick is 1 second (if I remember well), and a .NET tick is 100 nanoseconds.
If you've been encountering problems with nanoseconds, you might want to try using AddTick(10000000 * value).
You can't do without transaction logs in SQL Server, under any circumstances. The engine simply won't function.
You CAN set your recovery model to SIMPLE on your dev machines - that will prevent transaction log bloating when tran log backups aren't done.
ALTER DATABASE MyDB SET RECOVERY SIMPLE;
This is the right way to properly Dispose the DataTable
.
private DataTable CreateSchema_Table()
{
DataTable td = null;
try
{
td = new DataTable();
//use table DataTable here
return td.Copy();
}
catch { }
finally
{
if (td != null)
{
td.Constraints.Clear();
td.Clear();
td.Dispose();
td = null;
}
}
}
It seems like the other answers here all misunderstood your question. If I understand correctly, you want to make requests to localhost:6379 (the default for redis) and have them be forwarded, automatically, to the same port on your redis container.
https://unix.stackexchange.com/a/101906/38639 helped me get to the right answer.
First, you'll need to install the nc
command on your image. On CentOS, this package is called nmap-ncat, so in the example below, just replace this with the appropriate package if you are using a different OS as your base image.
Next, you'll need to tell it to run a certain command each time the container boots up. You can do this using CMD.
# Add this to your Dockerfile
RUN yum install -y --setopt=skip_missing_names_on_install=False nmap-ncat
COPY cmd.sh /usr/local/bin/cmd.sh
RUN chmod +x /usr/local/bin/cmd.sh
CMD ["/usr/local/bin/cmd.sh"]
Finally, we'll need to set up port-forwarding in cmd.sh. I found that nc
, even with the -l
and -k
options, will occasionally terminate when a request is completed, so I'm using a while-loop to ensure that it's always running.
# cmd.sh
#! /usr/bin/env bash
while nc -l -p 6379 -k -c "nc redis 6379" || true; do true; done &
tail -f /dev/null # Or any other command that never exits
