I faced the similar problem in no reason, i think it was caused by IDE(android studio). I have tried all of above solutions but not worked. Finally, in my own situation, i solved this problem by the following actions:
- Close the current project and remove it from the list of projects in android studio ,and reopen it by Open an existing Android Studio project
, then it may be worked. I hope that my experience will be useful for you.
If you are using version 0.14.0 or higher of the gradle plugin, you should replace "runProguard" with "minifyEnabled" in your build.gradle files.
runProguard was renamed to minifyEnabled in version 0.14.0. For more info, See Android Build System
There is no standard way to delay a call to a function other than to use a timer and events.
This sounds like the GUI anti pattern of delaying a call to a method so that you can be sure the form has finished laying out. Not a good idea.
Is it possible that this is an error avoidance technique (advisable or not..)? Since "" is still a string, you would be able to call string functions on it that would result in an exception if it was NULL?
N+1 SELECT problem is really hard to spot, especially in projects with large domain, to the moment when it starts degrading the performance. Even if the problem is fixed i.e. by adding eager loading, a further development may break the solution and/or introduce N+1 SELECT problem again in other places.
I've created open source library jplusone to address those problems in JPA based Spring Boot Java applications. The library provides two major features:

It's Feb 2013, and I can now target XP in VS2012 by setting:
Project Properties -> General -> Platform Toolset to:
Visual Studio 2012 - Windows XP (v110_xp)
You will have to redistribute the msvcp110.dll libraries et al with your application, which are found here: "<Program Files>\Microsoft Visual Studio 11.0\VC\redist\x86\Microsoft.VC110.CRT\"
Update Aug 2015 with Visual Studio 2015
There seems to be quite a selection now. I was able to compile application in VS2015 using Visual Studio 2015 - Windows XP (v140_xp) setting. To make it actually run on Win XP I had to deploy (copy alongside application) msvcr100.dll for Release build and msvcr110.dll and msvcr100d.dll for Debug build (note there is a difference in numbers 100 and 110, also debug lib msvcr100d.dll may not be redistributable)

rm uninstall-node.sh
Or you could check out this website: How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)
if this doesn't work, you need to remove node via control panel or any other method. As long as it gets removed.
If you use nvm
, you can use:
nvm install node
You can already check if it works, then you don't need to take the following steps with: npm -v
and then node -v
if you have nvm
installed:
command -v nvm
sudo npm uninstall npm -g
Or, if that fails, get the npm source code, and do:
sudo make uninstall
If you have nvm
installed, then use: nvm uninstall npm
npm install -g grunt
First you need to create a Service
. In that Service
, create a class extending LocationListener
. For this, use the following code snippet of Service
:
public class LocationService extends Service {
public static final String BROADCAST_ACTION = "Hello World";
private static final int TWO_MINUTES = 1000 * 60 * 2;
public LocationManager locationManager;
public MyLocationListener listener;
public Location previousBestLocation = null;
Intent intent;
int counter = 0;
@Override
public void onCreate() {
super.onCreate();
intent = new Intent(BROADCAST_ACTION);
}
@Override
public void onStart(Intent intent, int startId) {
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
listener = new MyLocationListener();
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 4000, 0, (LocationListener) listener);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 4000, 0, listener);
}
@Override
public IBinder onBind(Intent intent)
{
return null;
}
protected boolean isBetterLocation(Location location, Location currentBestLocation) {
if (currentBestLocation == null) {
// A new location is always better than no location
return true;
}
// Check whether the new location fix is newer or older
long timeDelta = location.getTime() - currentBestLocation.getTime();
boolean isSignificantlyNewer = timeDelta > TWO_MINUTES;
boolean isSignificantlyOlder = timeDelta < -TWO_MINUTES;
boolean isNewer = timeDelta > 0;
// If it's been more than two minutes since the current location, use the new location
// because the user has likely moved
if (isSignificantlyNewer) {
return true;
// If the new location is more than two minutes older, it must be worse
} else if (isSignificantlyOlder) {
return false;
}
// Check whether the new location fix is more or less accurate
int accuracyDelta = (int) (location.getAccuracy() - currentBestLocation.getAccuracy());
boolean isLessAccurate = accuracyDelta > 0;
boolean isMoreAccurate = accuracyDelta < 0;
boolean isSignificantlyLessAccurate = accuracyDelta > 200;
// Check if the old and new location are from the same provider
boolean isFromSameProvider = isSameProvider(location.getProvider(),
currentBestLocation.getProvider());
// Determine location quality using a combination of timeliness and accuracy
if (isMoreAccurate) {
return true;
} else if (isNewer && !isLessAccurate) {
return true;
} else if (isNewer && !isSignificantlyLessAccurate && isFromSameProvider) {
return true;
}
return false;
}
/** Checks whether two providers are the same */
private boolean isSameProvider(String provider1, String provider2) {
if (provider1 == null) {
return provider2 == null;
}
return provider1.equals(provider2);
}
@Override
public void onDestroy() {
// handler.removeCallbacks(sendUpdatesToUI);
super.onDestroy();
Log.v("STOP_SERVICE", "DONE");
locationManager.removeUpdates(listener);
}
public static Thread performOnBackgroundThread(final Runnable runnable) {
final Thread t = new Thread() {
@Override
public void run() {
try {
runnable.run();
} finally {
}
}
};
t.start();
return t;
}
public class MyLocationListener implements LocationListener
{
public void onLocationChanged(final Location loc)
{
Log.i("*****", "Location changed");
if(isBetterLocation(loc, previousBestLocation)) {
loc.getLatitude();
loc.getLongitude();
intent.putExtra("Latitude", loc.getLatitude());
intent.putExtra("Longitude", loc.getLongitude());
intent.putExtra("Provider", loc.getProvider());
sendBroadcast(intent);
}
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
public void onProviderDisabled(String provider)
{
Toast.makeText( getApplicationContext(), "Gps Disabled", Toast.LENGTH_SHORT ).show();
}
public void onProviderEnabled(String provider)
{
Toast.makeText( getApplicationContext(), "Gps Enabled", Toast.LENGTH_SHORT).show();
}
}
Add this Service
any where in your project, the way you want! :)
Another way to push items into array using Mongoose is- $addToSet, if you want only unique items to be pushed into array. $push operator simply adds the object to array whether or not the object is already present, while $addToSet does that only if the object is not present in the array so as not to incorporate duplicacy.
PersonModel.update(
{ _id: person._id },
{ $addToSet: { friends: friend } }
);
This will look for the object you are adding to array. If found, does nothing. If not, adds it to the array.
References:
Don't know if it will help, but you can try simulating a submit button click, instead of directly submitting the form. I have the following code in production, and it works fine:
$('.input').keypress(function(e) {
if(e.which == 13) {
jQuery(this).blur();
jQuery('#submit').focus().click();
}
});
Note: jQuery('#submit').focus() makes the button animate when enter is pressed.
This should work for you
public class MyActivity extends Activity {
protected ProgressDialog mProgressDialog;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
populateTable();
}
private void populateTable() {
mProgressDialog = ProgressDialog.show(this, "Please wait","Long operation starts...", true);
new Thread() {
@Override
public void run() {
doLongOperation();
try {
// code runs in a thread
runOnUiThread(new Runnable() {
@Override
public void run() {
mProgressDialog.dismiss();
}
});
} catch (final Exception ex) {
Log.i("---","Exception in thread");
}
}
}.start();
}
/** fake operation for testing purpose */
protected void doLongOperation() {
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
}
}
}
The java.time API (built into Java 8 and later), makes this a little easier.
If you know the input is in UTC, such as the Z
(for Zulu) on the end, the Instant
class can parse.
java.util.Date date = Date.from( Instant.parse( "2014-12-12T10:39:40Z" ));
If your input may be another offset-from-UTC values rather than UTC indicated by the Z
(Zulu) on the end, use the OffsetDateTime
class to parse.
OffsetDateTime odt = OffsetDateTime.parse( "2010-01-01T12:00:00+01:00" );
Then extract an Instant
, and convert to a java.util.Date
by calling from
.
Instant instant = odt.toInstant(); // Instant is always in UTC.
java.util.Date date = java.util.Date.from( instant );
Try \r\c
instead of \n
.
EDIT: I think @Robert Wilkinson had it right. \r\n
. Memory just isn't what it used to be.
There's a tidier way to include variables inside the escaped calc, as explained in this post: CSS3 calc() function doesn't work with Less #974
@variable: 2em;
body{ width: calc(~"100% - @{variable} * 2");}
By using the curly brackets you don't need to close and reopen the escaping quotes.
$(document).ready(function() {
$.fancybox(
'<p>Yes. It works <p>',
{
'autoDimensions' : false,
'width' : 400,
'height' : 200,
'transitionIn' : 'none',
'transitionOut' : 'none'
}
);
});
This will help..

I had this same issue. It turned out that I was loading the jQuery JavaScript file more than once on the page. This was due to included pages (or JSPs, in my case). Once I removed the duplicate reference to the jQuery js file, this error went away.
The easiest way is to redirect the output of the echo
by >>
:
echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile
You can also do this easily with gitk.
> gitk branch1 branch2
First click on the tip of branch1. Now right-click on the tip of branch2 and select Diff this->selected.
I have the same problem, I overcame it with an ugly -- but useful -- set of GOTOs.
The reason I call the "script runner" before everything is that I want to hide the complexity and ugly approach from any developer that just wants to work with the actual script. At the same time, I can make sure that the script is run in the two (extensible to three and more) databases in the exact same way.
GOTO ScriptRunner
ScriptExecutes:
--------------------ACTUAL SCRIPT--------------------
-------- Will be executed in DB1 and in DB2 ---------
--TODO: Your script right here
------------------ACTUAL SCRIPT ENDS-----------------
GOTO ScriptReturns
ScriptRunner:
USE DB1
GOTO ScriptExecutes
ScriptReturns:
IF (db_name() = 'DB1')
BEGIN
USE DB2
GOTO ScriptExecutes
END
With this approach you get to keep your variables and SQL Server does not freak out if you happen to go over a DECLARE statement twice.

try
{
if (!IsNumeric(data))
error = "Invalid Value - This is not a numeric value";
else
{
int num = int.Parse(data);
while (num > 0)
{
rem = num % 2;
num = num / 2;
result = rem.ToString() + result;
}
}
}
catch (Exception ex)
{
error = ex.Message;
}
return result;
}

I had a similar issue on MonoDroid when building a class library with Drawables and Layouts files that have "android:"
attribute in the xml. I get a similar error as the one in the question.
No resource identifier found for attribute 'textCursorDrawable' in package 'android'
I found from that "android: " attribute is only available in Android API Level 12+ and I was trying to build for an older version. Updating my project to build against Android 4.0 fixed the issue for me. Here is where I found the answer. https://groups.google.com/forum/?fromgroups#!topic/android-developers/ocxKphM5MWM Just make sure that you are building against the right API level if you get a similar issue, and ensure that the missing identifier exists in that API level that you are build against.
You almost got it. It should be this:
<input type="radio" name="group1" id="r1" value="1" />_x000D_
<label for="r1"> button one</label>
_x000D_
The value in for
should be the id of the element you are labeling.
I had the same problem.
Here is a workaround
android:inputType="textNoSuggestions|textVisiblePassword"
android:maxLength="6"
Swift 5:
func imageWithImage(_ image: UIImage?, scaledToSize newSize: CGSize) -> UIImage? {
UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0);
image?.draw(in: CGRect(x: 0.0, y: 0.0, width: newSize.width, height: newSize.height))
let newImage: UIImage? = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return newImage
}
Usage:
let img: UIImage? = imageWithImage(UIImage(named: "DefaultAvatar"), scaledToSize:CGSize(width: 20.0, height: 20.0))
I also got this error recently when using Anaconda on a Mac machine.
Here is what I found:
python3 -m pip install PyMySql,
pymysql module is under /Library/Python/3.7/site-packages
/opt/anaconda3/lib/python3.8/site-packages
Therefore, after copying pymysql module to the designated path, it runs correctly.

I think a better way to solve this would be to use the datetime callable:
from datetime import datetime
date = models.DateField(default=datetime.now)
Note that no parenthesis were used. If you used parenthesis you would invoke the now()
function just once (when the model is created). Instead, you pass the callable as an argument, thus being invoked everytime an instance of the model is created.
Credit to Django Musings. I've used it and works fine.
Is this what you need?
DataTable myDataTable = new DataTable();
List<int> myList = new List<int>();
foreach (DataRow row in myDataTable.Rows)
{
myList.Add((int)row[0]);
}
Do you want to end it with an "and"?
For this situation, I created an npm module.
Try arrford:
const arrford = require('arrford');
arrford(['run', 'climb', 'jump!']);
//=> 'run, climb, and jump!'
arrford(['run', 'climb', 'jump!'], false);
//=> 'run, climb and jump!'
arrford(['run', 'climb!']);
//=> 'run and climb!'
arrford(['run!']);
//=> 'run!'
npm install --save arrford

As TokenMacGuy says, you should use thread.is_alive()
to check if a thread is still running. To remove no longer running threads from your list you can use a list comprehension:
for t in my_threads:
if not t.is_alive():
# get results from thread
t.handled = True
my_threads = [t for t in my_threads if not t.handled]
This avoids the problem of removing items from a list while iterating over it.
It helps not to focus on the strong
or weak
part of the discussion. Instead focus on the cycle part.
A retain cycle is a loop that happens when Object A retains Object B, and Object B retains Object A. In that situation, if either object is released:
Thus, those two objects will just hang around in memory for the life of the program even though they should, if everything were working properly, be deallocated.
So, what we're worried about is retain cycles, and there's nothing about blocks in and of themselves that create these cycles. This isn't a problem, for example:
[myArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop){
[self doSomethingWithObject:obj];
}];
The block retains self
, but self
doesn't retain the block. If one or the other is released, no cycle is created and everything gets deallocated as it should.
Where you get into trouble is something like:
//In the interface:
@property (strong) void(^myBlock)(id obj, NSUInteger idx, BOOL *stop);
//In the implementation:
[self setMyBlock:^(id obj, NSUInteger idx, BOOL *stop) {
[self doSomethingWithObj:obj];
}];
Now, your object (self
) has an explicit strong
reference to the block. And the block has an implicit strong reference to self
. That's a cycle, and now neither object will be deallocated properly.
Because, in a situation like this, self
by definition already has a strong
reference to the block, it's usually easiest to resolve by making an explicitly weak reference to self
for the block to use:
__weak MyObject *weakSelf = self;
[self setMyBlock:^(id obj, NSUInteger idx, BOOL *stop) {
[weakSelf doSomethingWithObj:obj];
}];
But this should not be the default pattern you follow when dealing with blocks that call self
! This should only be used to break what would otherwise be a retain cycle between self and the block. If you were to adopt this pattern everywhere, you'd run the risk of passing a block to something that got executed after self
was deallocated.
//SUSPICIOUS EXAMPLE:
__weak MyObject *weakSelf = self;
[[SomeOtherObject alloc] initWithCompletion:^{
//By the time this gets called, "weakSelf" might be nil because it's not retained!
[weakSelf doSomething];
}];
Alternatively you could update brew
by installing it again. (Think I did this as El Capitan changed something)
Note: this is a heavy handed approach that will remove all applications installed via brew!
Try to install brew a fresh and it will tell how to uninstall.
At original time of writing to uninstall:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Edit: As of 2020 to uninstall:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
10 * * * Sun
Position 1 for minutes, allowed values are 1-60
position 2 for hours, allowed values are 1-24
position 3 for day of month ,allowed values are 1-31
position 4 for month ,allowed values are 1-12
position 5 for day of week ,allowed values are 1-7 or and the day starts at Monday.
By default, read.csv
checks the first few rows of your data to see whether to treat each variable as numeric. If it finds non-numeric values, it assumes the variable is character data, and character variables are converted to factors.
It looks like the PTS and MP variables in your dataset contain non-numerics, which is why you're getting unexpected results. You can force these variables to numeric with
point <- as.numeric(as.character(point))
time <- as.numeric(as.character(time))
But any values that can't be converted will become missing. (The R FAQ gives a slightly different method for factor -> numeric conversion but I can never remember what it is.)
If you pass the -v
flag to the ansible-playbook command, then ansible will show the output on your terminal.
For your use case, you may want to try using the fetch module to copy the public key from the server to your local machine. That way, it will only show a "changed" status when the file changes.
The problem, in my case, was that I was using Amazon's Cloudflare and Cloudfront's Cloudfront in tandem, and Cloudfront did not like the settings that I had provided Cloudflare.
More specifically, in the Crypto settings on Cloudflare, I had set the "Minimum TLS Settings" to 1.2, without enabling the TLS 1.2 communication setting for the distribution in Cloudfront. This was enough to make Cloudfront declare a 502 Bad Gateway error when it tried to connect to the Cloudflare-protected server.
To fix this, I had to disable SSLv3 support in the Origin Settings for that Cloudfront distribution, and enable TLS 1.2 as a supported protocol for that origin server.
To debug this problem, I used command-line versions of curl, to see what Cloudfront was actually returning when you asked for an image from its CDN, and I also used the command-line version of openssl, to determine exactly which protocols Cloudflare was offering (it wasn't offering TLS 1.0).
tl:dr; make sure everything accepts and asks for TLS 1.2, or whatever latest and greatest TLS everyone is using by the time you read this.
The seamless
attribute no longer exists. It was originally pitched to be included in the first HTML5 spec, but subsequently dropped. An unrelated attribute of the same name made a brief cameo in the HTML5.1 draft, but that too was ditched mid-2016:
So I think the gist of it all both from the implementor side and the web-dev side is that
seamless
as-specced doesn’t seem to be what anybody wanted to begin with. Or at least it’s more than anybody actually wanted. And anyway like @annevk says, it’s seems a lot of it’s since been “overcome by events” in light of Shadow DOM.
In other words: purge the seamless
attribute from your memory, and pretend it never existed.
For posterity's sake, here's my original answer from five years ago:
The attribute is in draft mode at the moment. For that reason, none of the current browsers are supporting it yet (as the implementation is subject to change). In the meantime, it's best just to use CSS to strip the borders/scrollbars from the iframe:
iframe[seamless]{
background-color: transparent;
border: 0px none transparent;
padding: 0px;
overflow: hidden;
}
There's more to the seamless attribute than what can be added with CSS: part of the reasoning behind the attribute was to allow nested content to inherit the same styles applied to the iframe (acting as though the embedded document was one big nested inside the element, for example).
Lastly, versions of Internet Explorer (8 and earlier) require additional attributes in order to remove the borders, scrollbars and background colour:
<iframe frameborder="0" allowtransparency="true" scrolling="no" src="..."></iframe>
Naturally, this doesn't validate. So it's up to you how to handle it. My (picky) approach would be to sniff the agent string and add the attributes for IE versions earlier than 9.
Hope that helps. :)
By default WampServer is installed to port 80 which is already used by IIS. To set WampServer to use an open port, left click on the WampServer icon in the system tray and go to Apache > httpd.conf
Open the httpd.conf in Notepad. press ctrl+f and search for "Listen 80", change this line to "Listen 8080" (u can change this port as what you want), and then close and save the httpd.conf file.
Open a web browser and enter "[];, this will open the WampServer configuration page where you can configure Apache, MySQL, and PHP.
and some times this problem may occur because of skype also use 80 as default port hope this will help
So here's the best way to do this FOR ALL BROWSERS:
Forget CSS!
<p>Append Image:</p>
<input type="button" id="clickImage" value="Add Image" />
<input type="file" name="images[]" id="images" multiple />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" charset="utf-8"></script>
<script>
$('#images').hide();
$('#clickImage').click( function() {
$('#images').trigger('click');
});
</script>
You can use Named Sections.
_Layout.cshtml
<head>
<script type="text/javascript" src="@Url.Content("/Scripts/jquery-1.6.2.min.js")"></script>
@RenderSection("JavaScript", required: false)
</head>
_SomeView.cshtml
@section JavaScript
{
<script type="text/javascript" src="@Url.Content("/Scripts/SomeScript.js")"></script>
<script type="text/javascript" src="@Url.Content("/Scripts/AnotherScript.js")"></script>
}
You can use eval(jsonString) if you trust the data in the string, otherwise you'll need to parse it properly - check json.org for some code samples.
You need to remember that IQueryable queries are not actually executed against the data store until you enumerate them.
using (var dataContext = new dataContext())
{
This line of code doesn't actually do anything other than build the SQL statement
users = dataContext.Users.Where(x => x.AccountID == accountId && x.IsAdmin == false);
.Any() is an operation that enumerates the IQueryable, so the SQL is sent to the data source (through dataContext), and then the .Any() operations is executed against it
if(users.Any() == false)
{
return null;
}
}
Your "problem" line is reusing the sql built above, and then doing an additional operation (.Select()), which just adds to the query. If you left it here, no exception, except your problem line
return users.Select(x => x.ToInfo()).ToList(); // this line is the problem
calls .ToList(), which enumerates the IQueryable, which causes the SQL to be sent to the datasource through the dataContext that was used in the original LINQ query. Since this dataContext has been disposed, it is no longer valid, and .ToList() throws an exception.
That is the "why it doesn't work". The fix is to move this line of code inside the scope of your dataContext.
How to use it properly is another question with a few arguably correct answers that depend on your application (Forms vs. ASP.net vs. MVC, etc.). The pattern that this implements is the Unit of Work pattern. There is almost no cost to creating a new context object, so the general rule is to create one, do your work, and then dispose of it. In web apps, some people will create a Context per request.
You can use String.valueOf() for float, double, int, boolean etc.
double d = 0;
float f = 0;
int i = 0;
short i1 = 0;
char c = 0;
boolean bool = false;
char[] chars = {};
Object obj = new Object();
String.valueOf(d);
String.valueOf(i);
String.valueOf(i1);
String.valueOf(f);
String.valueOf(c);
String.valueOf(chars);
String.valueOf(bool);
String.valueOf(obj);
Look to your local svn repo and look into directory .svn . there is file: entries look into them and you'll see lines begins with: svn+ssh://
this is your first configuration maked by svn checkout 'repo_source' or svn co 'repo_source'
if you want to change this, te best way is completly refresh this repository. update/commit what you should for save work. then remove completly directory and last step is create this by svn co/checkout 'URI-for-main-repo' [optionally local directory for store]
you should select connection method to repo file:// svn+ssh:// http:// https:// or other described in documentation.
after that you use svn update/commit as usual.
this topic looks like out of topic. better you go to superuser pages.
To select the first column of a table you can use this syntax
tr td:nth-child(1n + 2){
padding-left: 10px;
}
Here is my solution in Python 3.x to return geo-location info given a dataframe containing IP Address(s); efficient parallelized application of function on vectorized pd.series/dataframe is the way to go.
Will contrast performance of two popular libraries to return location.
TLDR: use geolite2 method.
1. geolite2
package from geolite2
library
Input
# !pip install maxminddb-geolite2
import time
from geolite2 import geolite2
geo = geolite2.reader()
df_1 = train_data.loc[:50,['IP_Address']]
def IP_info_1(ip):
try:
x = geo.get(ip)
except ValueError: #Faulty IP value
return np.nan
try:
return x['country']['names']['en'] if x is not None else np.nan
except KeyError: #Faulty Key value
return np.nan
s_time = time.time()
# map IP --> country
#apply(fn) applies fn. on all pd.series elements
df_1['country'] = df_1.loc[:,'IP_Address'].apply(IP_info_1)
print(df_1.head(), '\n')
print('Time:',str(time.time()-s_time)+'s \n')
print(type(geo.get('48.151.136.76')))
Output
IP_Address country
0 48.151.136.76 United States
1 94.9.145.169 United Kingdom
2 58.94.157.121 Japan
3 193.187.41.186 Austria
4 125.96.20.172 China
Time: 0.09906983375549316s
<class 'dict'>
2. DbIpCity
package from ip2geotools
library
Input
# !pip install ip2geotools
import time
s_time = time.time()
from ip2geotools.databases.noncommercial import DbIpCity
df_2 = train_data.loc[:50,['IP_Address']]
def IP_info_2(ip):
try:
return DbIpCity.get(ip, api_key = 'free').country
except:
return np.nan
df_2['country'] = df_2.loc[:, 'IP_Address'].apply(IP_info_2)
print(df_2.head())
print('Time:',str(time.time()-s_time)+'s')
print(type(DbIpCity.get('48.151.136.76',api_key = 'free')))
Output
IP_Address country
0 48.151.136.76 US
1 94.9.145.169 GB
2 58.94.157.121 JP
3 193.187.41.186 AT
4 125.96.20.172 CN
Time: 80.53318452835083s
<class 'ip2geotools.models.IpLocation'>
A reason why the huge time difference could be due to the Data structure of the output, i.e direct subsetting from dictionaries seems way more efficient than indexing from the specicialized ip2geotools.models.IpLocation object.
Also, the output of the 1st method is dictionary containing geo-location data, subset respecitively to obtain needed info:
x = geolite2.reader().get('48.151.136.76')
print(x)

The canonical way to do this with Rails 3:
Foo.includes(:bar).where("bars.id IS NOT NULL")
ActiveRecord 4.0 and above adds where.not
so you can do this:
Foo.includes(:bar).where.not('bars.id' => nil)
Foo.includes(:bar).where.not(bars: { id: nil })
When working with scopes between tables, I prefer to leverage merge
so that I can use existing scopes more easily.
Foo.includes(:bar).merge(Bar.where.not(id: nil))
Also, since includes
does not always choose a join strategy, you should use references
here as well, otherwise you may end up with invalid SQL.
Foo.includes(:bar)
.references(:bar)
.merge(Bar.where.not(id: nil))
Just want to point out something on @codingbadger answer. When using "ProgressBarRenderer" you should always check for "ProgressBarRenderer.IsSupported" before using the class. For me, this has been a nightmare with Visual Styles errors in Win7 that I couldn't fix. So, a better approach and workaround for the solution would be:
Rectangle clip = new Rectangle(rect.X, rect.Y, (int)Math.Round(((float)Value / Maximum) * rect.Width), rect.Height);
if (ProgressBarRenderer.IsSupported)
ProgressBarRenderer.DrawHorizontalChunks(g, clip);
else
g.FillRectangle(new SolidBrush(this.ForeColor), clip);
Notice that the fill will be a simple rectangle and not chunks. Chunks will be used only if ProgressBarRenderer is supported
$percentage = 50;
$totalWidth = 350;
$new_width = ($percentage / 100) * $totalWidth;
Since you are working with svg elements you could feed your leaflet marker's icon with L.divIcon's html
property instead of using iconUrl from L.icon to link your image.
L.marker(latlng, {
icon: L.divIcon({
className: 'ship-div-icon',
html: '<svg>...</svg>'
})
}).addTo(map);
Then use CSS fill property to color your svg shape. It could be useful to add a class\es to svg's path\s to have precise control
<svg ... >
<g>
<path class="ship-icon" ... />
</g>
...
</svg>
At the end, as I also needed to randomly change the marker color I changed directly the path's fill property at the time of creating the marker
var pathFillColor = '#'+(Math.random()*0xFFFFFF<<0).toString(16);
L.marker(latlng, {
icon: L.divIcon({
className: 'ship-div-icon',
html: '<svg ... ><g><path fill="'+pathFillColor+'" ... /> </g></svg>'
})
}).addTo(map);
Use the .val()
method to get the actual value of the element you need.
Without any configuration, you can simply issue the following command (modifying myusername
and mydomain
with your own information):
cntlm -u myusername -d mydomain -H
or
cntlm -u myusername@mydomain -H
It will ask you the password of myusername
and will give you the following output:
PassLM 1AD35398BE6565DDB5C4EF70C0593492
PassNT 77B9081511704EE852F94227CF48A793
PassNTLMv2 A8FC9092D566461E6BEA971931EF1AEC # Only for user 'myusername', domain 'mydomain'
Then create the file cntlm.ini
(or cntlm.conf
on Linux using default path) with the following content (replacing your myusername
, mydomain
and A8FC9092D566461E6BEA971931EF1AEC
with your information and the result of the previous command):
Username myusername
Domain mydomain
Proxy my_proxy_server.com:80
NoProxy 127.0.0.*, 192.168.*
Listen 127.0.0.1:5865
Gateway yes
SOCKS5Proxy 5866
Auth NTLMv2
PassNTLMv2 A8FC9092D566461E6BEA971931EF1AEC
Then you will have a local open proxy on local port 5865
and another one understanding SOCKS5 protocol at local port 5866
.
Can you try annotating only your concrete implementation with @Component
? Maybe the following answer could help. It is kind of a similar problem. I usually put Spring annotations in the implementation classes.
I've used this:
RewriteEngine On
# Unless directory, remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ http://example.com/folder/$1 [R=301,L]
# Redirect external .php requests to extensionless URL
RewriteCond %{THE_REQUEST} ^(.+)\.php([#?][^\ ]*)?\ HTTP/
RewriteRule ^(.+)\.php$ http://example.com/folder/$1 [R=301,L]
# Resolve .php file for extensionless PHP URLs
RewriteRule ^([^/.]+)$ $1.php [L]

For existing project end existing repository with files:
git init
git remote add origin <.git>
git checkout -b master
git branch --set-upstream-to=origin/master master
git pull --allow-unrelated-histories
If you're using jQuery UI dialog, you could just style the modal to appear with the position fixed in the window so it doesn't pop-up out of view, negating the need to scroll. Otherwise,
var scrollTop = function() {
window.scrollTo(0, 0);
};
should do the trick.
I found this topic while searching for run script for startup and shutdown Windows 10. Those answers above didn't working. For me on windows 10 worked when I put scripts to task scheduler. How to do this: press window key and write Task scheduler, open it, then on the right is Add task... button. Here you can add scripts. PS: I found action for startup and logout user, there is not for shutdown.
You may have no app with that same ID, but someone else may. The IDs must be unique globally, and not only within your own apps.
HashMap
is unordered per the second line of the documentation:
This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time.
Perhaps you can do as aix suggests and use a LinkedHashMap
, or another ordered collection. This link can help you find the most appropriate collection to use.
The default generator for Windows seems to be set to NMAKE. Try to use:
cmake -G "MinGW Makefiles"
Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.
First check the list contains some values:
if (list.isEmpty()) {
listview.setVisibility(View.GONE);
}
If it is then OK, otherwise use:
else {
listview.setVisibility(View.VISIBLE);
}
Just use negative margins, in the second div say:
<div style="margin-top: -25px;">
And make sure to set the z-index property to get the layering you want.
add this to your stylesheet. line-height should match the height of your logo
.navbar-nav li a {
line-height: 50px;
}

I am using Visual Studio 2013 Update 2. In my case, I have a web project and a Web Api project and unit test project and other class libraries in a single solution.
I've spent couple of days to solve the problem. Below is the step-by-step solution that I have found.
Newtonsoft.Json
packs from solution by using below query from Package Manager Console ( to get it View > Other Window > Package Manager Console ).uninstall-package newtonsoft.json -force
Newtonsoft.Json
from Package Manager Consoleinstall-package newtonsoft.json
Newtonsoft.Json
, I have encountered with the following error.The 'Newtonsoft.Json 10.0.3' package requires NuGet client version '2.12' or above, but the current NuGet version i s '2.8.50313.46'
Tools > Extensions and Updates... > In left pane.. select Updates > Visual Studio Gallery.
Update the NuGet Package Manager Extension. Follow the steps that are coming afterwards.
Visual Studio will take a restart after that.
Execute step 6 again.
After Installation packages.config will be added with this below line
<package id="Newtonsoft.Json" version="10.0.3" targetFramework="net451" />
After installation web.config will be added with this below lines
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-10.0.0.0" newVersion="10.0.0.0" />
</dependentAssembly>
It will execute successfully, if there is no other error.

This helped me get to my answer. There are two php.ini
files located, in my case, for wamp. One is under the php folder and the other one is in the C:\wamp\bin\apache\Apachex.x.x\bin
folder. When connecting to SQL through sqlsrv_connect
function, we are referring to the php.ini
file in the apache
folder. Add the following (as per your version) to this file:
extension=c:/wamp/bin/php/php5.4.16/ext/php_sqlsrv_53_ts.dll
You can do this using $lookup
aggregation as well and probably the best way as now populate is becoming extinct from the mongo
Project.aggregate([
{ "$match": { "_id": mongoose.Types.ObjectId(id) } },
{ "$lookup": {
"from": Pages.collection.name,
"let": { "pages": "$pages" },
"pipeline": [
{ "$match": { "$expr": { "$in": [ "$_id", "$$pages" ] } } },
{ "$lookup": {
"from": Component.collection.name,
"let": { "components": "$components" },
"pipeline": [
{ "$match": { "$expr": { "$in": [ "$_id", "$$components" ] } } },
],
"as": "components"
}},
],
"as": "pages"
}}
])
if it helps someone else, I had an activity with 2 layouts that I toggled on and off for visibilty, trying to emulate a kind of page1 > page2 structure. if they were on page 2 and pressed the back button I wanted them to go back to page 1, if they pressed the back button on page 1 it should still work as normal. Its pretty basic but it works
@Override
public void onBackPressed() {
// check if page 2 is open
RelativeLayout page2layout = (RelativeLayout)findViewById(R.id.page2layout);
if(page2layout.getVisibility() == View.VISIBLE){
togglePageLayout(); // my method to toggle the views
return;
}else{
super.onBackPressed(); // allows standard use of backbutton for page 1
}
}
hope it helps someone, cheers

As I can see you wrote <target depends="build-subprojects,build-project" name="build"/>
, then you wrote <target name="build-subprojects"/>
(it does nothing). Could it be a reason?
Does this <echo message="${ant.project.name}: ${ant.file}"/>
print appropriate message? If no then target is not running.

I was looking for a similar query where I needed to use the first day of a month in my query.
The last_day
function didn't work for me but DAYOFMONTH
came in handy.
So if anyone is looking for the same issue, the following code returns the date for first day of the current month.
SELECT DATE_SUB(CURRENT_DATE, INTERVAL DAYOFMONTH(CURRENT_DATE)-1 DAY);
Comparing a date column with the first day of the month :
select * from table_name where date between
DATE_SUB(CURRENT_DATE, INTERVAL DAYOFMONTH(CURRENT_DATE)-1 DAY) and CURRENT_DATE
Here is what I would recommend.
It should conform to C89, and be completely portable. In particular, it works also on pipes and sockets on POSIXy systems.
The idea is that we read the input in large-ish chunks (READALL_CHUNK
), dynamically reallocating the buffer as we need it. We only use realloc()
, fread()
, ferror()
, and free()
:
#include <stdlib.h>
#include <stdio.h>
#include <errno.h>
/* Size of each input chunk to be
read and allocate for. */
#ifndef READALL_CHUNK
#define READALL_CHUNK 262144
#endif
#define READALL_OK 0 /* Success */
#define READALL_INVALID -1 /* Invalid parameters */
#define READALL_ERROR -2 /* Stream error */
#define READALL_TOOMUCH -3 /* Too much input */
#define READALL_NOMEM -4 /* Out of memory */
/* This function returns one of the READALL_ constants above.
If the return value is zero == READALL_OK, then:
(*dataptr) points to a dynamically allocated buffer, with
(*sizeptr) chars read from the file.
The buffer is allocated for one extra char, which is NUL,
and automatically appended after the data.
Initial values of (*dataptr) and (*sizeptr) are ignored.
*/
int readall(FILE *in, char **dataptr, size_t *sizeptr)
{
char *data = NULL, *temp;
size_t size = 0;
size_t used = 0;
size_t n;
/* None of the parameters can be NULL. */
if (in == NULL || dataptr == NULL || sizeptr == NULL)
return READALL_INVALID;
/* A read error already occurred? */
if (ferror(in))
return READALL_ERROR;
while (1) {
if (used + READALL_CHUNK + 1 > size) {
size = used + READALL_CHUNK + 1;
/* Overflow check. Some ANSI C compilers
may optimize this away, though. */
if (size <= used) {
free(data);
return READALL_TOOMUCH;
}
temp = realloc(data, size);
if (temp == NULL) {
free(data);
return READALL_NOMEM;
}
data = temp;
}
n = fread(data + used, 1, READALL_CHUNK, in);
if (n == 0)
break;
used += n;
}
if (ferror(in)) {
free(data);
return READALL_ERROR;
}
temp = realloc(data, used + 1);
if (temp == NULL) {
free(data);
return READALL_NOMEM;
}
data = temp;
data[used] = '\0';
*dataptr = data;
*sizeptr = used;
return READALL_OK;
}
Above, I've used a constant chunk size, READALL_CHUNK
== 262144 (256*1024
). This means that in the worst case, up to 262145 chars are wasted (allocated but not used), but only temporarily. At the end, the function reallocates the buffer to the optimal size. Also, this means that we do four reallocations per megabyte of data read.
The 262144-byte default in the code above is a conservative value; it works well for even old minilaptops and Raspberry Pis and most embedded devices with at least a few megabytes of RAM available for the process. Yet, it is not so small that it slows down the operation (due to many read calls, and many buffer reallocations) on most systems.
For desktop machines at this time (2017), I recommend a much larger READALL_CHUNK
, perhaps #define READALL_CHUNK 2097152
(2 MiB).
Because the definition of READALL_CHUNK
is guarded (i.e., it is defined only if it is at that point in the code still undefined), you can override the default value at compile time, by using (in most C compilers) -DREADALL_CHUNK=2097152
command-line option -- but do check your compiler options for defining a preprocessor macro using command-line options.

Density was the issue here, I needed to have this in the AndroidManifest.xml
<supports-screens
android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="true"
android:anyDensity="true"

The most important is the android:anyDensity =" true ".
Don't forget to add the following in the AndroidManifest.xml

android:configChanges="locale"
This version is needed when you build for Android 4.2 (API level 17) explanation here:
android:configChanges="locale|layoutDirection"

Your web server isn't running! You need to find the XAMPP control panel and start the web server up.
Of course, you might find other problems after that, but this is the first step.
In the other hand, using REST API of other servers are very popular in PHP. Suppose you are looking for a way to redirect some HTTP requests into the other server (for example getting an xml file). Here is a PHP package to help you:
https://github.com/romanpitak/PHP-REST-Client
So, getting the xml file:
$client = new Client('http://example.com');
$request = $client->newRequest('/filename.xml');
$response = $request->getResponse();
echo $response->getParsedResponse();
I would simply change a column name to the dataset with the new name I want with the following code: names(dataset)[index_value] <- "new_col_name"
You can leverage selectNodeContents which is supported by modern browsers.
var el = document.getElementById('idOfYoursContentEditable');
var selection = window.getSelection();
var range = document.createRange();
selection.removeAllRanges();
range.selectNodeContents(el);
range.collapse(false);
selection.addRange(range);
el.focus();
Employee emp1 = new Employee() { ID = 1, Name = "Narendra1", Salary = 11111, Experience = 3, Age = 30 };Employee emp2 = new Employee() { ID = 2, Name = "Narendra2", Salary = 21111, Experience = 10, Age = 38 };
Employee emp3 = new Employee() { ID = 3, Name = "Narendra3", Salary = 31111, Experience = 4, Age = 33 };
Employee emp4 = new Employee() { ID = 3, Name = "Narendra4", Salary = 41111, Experience = 7, Age = 33 };
List<Employee> lstEmployee = new List<Employee>();
lstEmployee.Add(emp1);
lstEmployee.Add(emp2);
lstEmployee.Add(emp3);
lstEmployee.Add(emp4);
var eemmppss=lstEmployee.Select(cc=>new {cc.ID,cc.Age}).Distinct();
Environment returns user data directory. And getFilesDir returns application data directory.
So all of these answers are basically the same one. They only address one idea: it has to be DNS related. Well, that is not the only part of this it turns out. After many changes, I was getting nowhere reading the next "same answer" hoping that it would just go my way.
What did the trick for me was to adjust my versions of Apache. I think what the deal was, is that the one of the configuration files get a path off or that the install due to IIS may have been messed up /
or /
or /etc
. And so forcing a version change readdresses everything from your firewall to bad configurations.
In fact, when I switched back to Apache 2.4.2 it goes back to being a forbidden. And as soon as I go back to Apache 2.4.4 it comes back up. That rules out local network issues. I just wanted to point out that all of the answers here are the same and that I have been able to kill the forbidden by changing the Apache version.
You're close
sudo apt-get install php-xml
Then you need to restart apache so it takes effect
sudo service apache2 restart
It occurs when IIS is not being connected to SQL SERVER. For a solution, see this screenshot:

Replacing for Removing is not quite logical. String.filter allows to iterate a string char by char and keep only true assertion.
Swift 4 & 5
var aString = "Optional(\"5\")"
aString = aString.filter { $0 != "\"" }
> Optional(5)
Or to extend
var aString = "Optional(\"5\")"
let filteredChars = "\"\n\t"
aString = aString.filter { filteredChars.range(of: String($0)) == nil }
> Optional(5)
You need to detect the click from js side, your HTML remaining same. Note: this method is deprecated since v3.5.5 and removed in v4.
$("button").click(function() {
var $btn = $(this);
$btn.button('loading');
// simulating a timeout
setTimeout(function () {
$btn.button('reset');
}, 1000);
});
Also, don't forget to load jQuery and Bootstrap js (based on jQuery) file in your page.
Here are the steps to install JSToolNPP
plugin on your Notepad++.
Download 64bit version from Sourceforge or the 32bit version if you are on a 32-bit OS.
64bit - JSToolNPP.1.21.0.uni.64.zip: Download from SourceForget.net
Notepad++ before installation
Unzip the downloaded JSToolNPP.1.21.0.uni.64
and copy the JSMinNPP.dll
and place it under C:\Program Files\Notepad++\plugins
.
Close Notepad++ and reopen it. If you have downloaded an incompatible dll, then it will complain, else it will open successfully. If it complains about incompatibility, go back to STEP 1 and download the correct bit version as per your OS. Check Plugins in Notepad++.
Paste a sample unformatted but valid JSON data in Notepad++.
Select all text in Notepad++ (CTRL+A)
and format using Plugins -> JSTool -> JSFormat
.
NOTE: On side note, if you do not want to install any plugins like this, I would recommend using the following 2 best online formatters.
Decoding using convenience initialiser - Swift 5
extension UIImage {
convenience init?(base64String: String) {
guard let data = Data(base64Encoded: base64String) else { return nil }
self.init(data: data)
}
}
and what is the correct way to change the background color on any View?
On any View
? What you have is correct, though you should drop the invalidate()
call.
However, some Views
already have backgrounds. A Button
, for example, already has a background: the face of the button itself. This background is a StateListDrawable
, which you can find in android-2.1/data/res/drawable/btn_default.xml
in your Android SDK installation. That, in turn, refers to a bunch of nine-patch bitmap images, available in multiple densities. You would need to clone and modify all of that to accomplish your green goals.
In short, you will be better served finding another UI pattern rather than attempting to change the background of a Button
.
There is nothing wrong with syntax of
$('#part' + number).html(text);
jQuery accepts a String (usually a CSS Selector) or a DOM Node as parameter to create a jQuery Object.
In your case you should pass a String to $()
that is
$(<a string>)
Make sure you have access to the variables number
and text
.
To test do:
function(){
alert(number + ":" + text);//or use console.log(number + ":" + text)
$('#part' + number).html(text);
});
If you see you dont have access, pass them as parameters to the function, you have to include the uual parameters for $.get and pass the custom parameters after them.
in c# 7.0 we can do :
var a = reader["ERateCode"] as string;
var b = reader["ERateLift"] as int?;
var c = reader["Id"] as int?;
so it will keep null value if it is.
While I respect the answer from qkrijger explaining how you can work around this issue I think there is a lot more we can learn about what's going on here ...
To actually answer your question of "why" ... I think it would for helpful for you to understand how the docker stop
command works and that all processes should be shutdown cleanly to prevent problems when you try to restart them (file corruption etc).
Problem: What if docker did start SSH from it's command and started RabbitMQ from your Docker file? "The docker stop command attempts to stop a running container first by sending a SIGTERM signal to the root process (PID 1) in the container." Which process is docker tracking as PID 1 that will get the SIGTERM? Will it be SSH or Rabbit?? "According to the Unix process model, the init process -- PID 1 -- inherits all orphaned child processes and must reap them. Most Docker containers do not have an init process that does this correctly, and as a result their containers become filled with zombie processes over time."
Answer: Docker simply takes that last CMD as the one that will get launched as the root process with PID 1 and get the SIGTERM from docker stop
.
Suggested solution: You should use (or create) a base image specifically made for running more than one service, such as phusion/baseimage
It should be important to note that tini exists exactly for this reason, and as of Docker 1.13 and up, tini is officially part of Docker, which tells us that running more than one process in Docker IS VALID .. so even if someone claims to be more skilled regarding Docker, and insists that you absurd for thinking of doing this, know that you are not. There are perfectly valid situations for doing so.
Good to know:
Coming from Linux background. I would prefer using something similar to grep, therefore I use Select-String. So even if someone is not sure of the complete module name. They can provide the initials and determine whether the module exists or not.
Get-Module -ListAvailable -All | Select-String Module_Name
(can be a part of the module name)
You should also take a look at the at
command in Windows. It will launch a program at a certain time in the background which works in this case.
Another option is to use the nssm
service manager software. This will wrap whatever command you are running as a windows service.
UPDATE:
nssm
isn't very good. You should instead look at WinSW project. https://github.com/kohsuke/winsw
Its very simple.
Example JSON:
{
"value":1
}
int z = jsonObject.getInt("value");
Strangely, the answers above removes the 'duplicates' but what if I want to remove the duplicated value also?? The following should be useful and does not create a new object in memory!
def dictRemoveDuplicates(self):
a=[[1,'somevalue1'],[1,'somevalue2'],[2,'somevalue1'],[3,'somevalue4'],[5,'somevalue5'],[5,'somevalue1'],[5,'somevalue1'],[5,'somevalue8'],[6,'somevalue9'],[6,'somevalue0'],[6,'somevalue1'],[7,'somevalue7']]
print(a)
temp = 0
position = -1
for pageNo, item in a:
position+=1
if pageNo != temp:
temp = pageNo
continue
else:
a[position] = 0
a[position - 1] = 0
a = [x for x in a if x != 0]
print(a)
and the o/p is:
[[1, 'somevalue1'], [1, 'somevalue2'], [2, 'somevalue1'], [3, 'somevalue4'], [5, 'somevalue5'], [5, 'somevalue1'], [5, 'somevalue1'], [5, 'somevalue8'], [6, 'somevalue9'], [6, 'somevalue0'], [6, 'somevalue1'], [7, 'somevalue7']]
[[2, 'somevalue1'], [3, 'somevalue4'], [7, 'somevalue7']]
You have one thing to configure. The example is based on GitHub but this shouldn't change the process:
$ git config --global [email protected]:.insteadOf https://github.com/
$ cat ~/.gitconfig
[url "[email protected]:"]
insteadOf = https://github.com/
$ go get github.com/private/repo
For Go modules to work (with Go 1.11 or newer), you'll also need to set the GOPRIVATE
variable, to avoid using the public servers to fetch the code:
export GOPRIVATE=github.com/private/repo
A little contribution to the two-bit-fool's answer:
As described on the table on droid phones "orientationchange" event gets fired earlier than "resize" event thus blocking the next resize call (because of the if statement). Width property is still not set.
A workaround though maybe not a perfect one could be to not fire the "orientationchange" event. That can be archived by wrapping "orientationchange" event binding in "if" statement:
if (!navigator.userAgent.match(/android/i))
{
window.addEventListener("orientationchange", checkOrientation, false);
}
Hope it helps
(tests were done on Nexus S)
You could use the .attr()
function:
$(this).attr('data-fullText')
or if you lowercase the attribute name:
data-fulltext="This is a span element"
then you could use the .data()
function:
$(this).data('fulltext')
The .data()
function expects and works only with lowercase attribute names.
You could probably use an inheritance structure although the more I played with this the dirtier I felt.

I know that is to late, but I want to share my answer. What I did it's save de script's tags in a HTML file, locking up the scripts on my Index file in a div with an id, something like this.
<div id="ScriptsReload"><script src="js/script.js"></script></div>
and when I wanted to refresh I just used.
$("#ScriptsReload").load("html_with_scripts_tags.html", "", function(
response,
status,
request
) {
});
This question already has a great answer but in the spirit of exploring all possibilities here is another technique to reorder dom elements whilst still allowing them to take up their space, unlike the absolute positioning method.
This method works in all modern browsers and IE9+ (basically any browser that supports display:table) it has a drawback that it can only be used on a max of 3 siblings though.
//the html
<div class='container'>
<div class='div1'>1</div>
<div class='div2'>2</div>
<div class='div3'>3</div>
</div>
//the css
.container {
display:table;
}
.div1 {
display:table-footer-group;
}
.div2 {
display:table-header-group;
}
.div3 {
display:table-row-group;
}
This will reorder the elements from 1,2,3 to 2,3,1. Basically anything with the display set to table-header-group will be positioned at the top and table-footer-group at the bottom. Naturally table-row-group puts an element in the middle.
This method is quick with good support and requires much less css than the flexbox approach so if you are only looking to swap a few items around for a mobile layout for example then dont rule out this technique.
You can check out a live demo on codepen: http://codepen.io/thepixelninja/pen/eZVgLx
string InstallPath = (string)Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\MyApplication\AppPath", "Installed", null);
if (InstallPath != null)
{
// Do stuff
}
That code should get your value. You'll need to be
using Microsoft.Win32;
for that to work though.
For mysql 5.7.21 I use the following and works fine:
CREATE TABLE Posts
(
modified_at
timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
created_at
timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
)
When using kill -3 one should see the thread dump in the standard output. Most of the application servers write the standard output to a separate file. You should find it there when using kill -3. There are multiple ways of getting thread dumps:
kill -3 <PID>
: Gives output to standard output.For hotspot VM's we can also use jstack
command to generate a thread dump. It’s a part of the JDK. Syntax is as follows:
Usage:
jstack [-l] <pid> (to connect to running process)
jstack -F [-m] [-l] <pid>(to connect to a hung process)
- For JRockit JVM we can use JRCMD command which comes with JDK Syntax:
jrcmd <jrockit pid> [<command> [<arguments>]] [-l] [-f file] [-p] -h]
Use a seperate column to indicate the join condition
SELECT t.importid,
case
when t.importid = g.home
then 'home'
else 'away'
end as join_condition,
g.network,
g.date_start
FROM game g
INNER JOIN team t ON (t.importid = g.home OR t.importid = g.away)
ORDER BY date_start DESC
LIMIT 7
The error means that you have data in other tables that references the data you are trying to delete.
You would need to either drop and recreate the constraints or delete the data that the Foreign Key references.
Suppose you have the following tables
dbo.Students
(
StudentId
StudentName
StudentTypeId
)
dbo.StudentTypes
(
StudentTypeId
StudentType
)
Suppose a Foreign Key constraint exists between the StudentTypeId
column in StudentTypes
and the StudentTypeId
column in Students
If you try to delete all the data in StudentTypes
an error will occur as the StudentTypeId
column in Students
reference the data in the StudentTypes
table.
EDIT:
DELETE
and TRUNCATE
essentially do the same thing. The only difference is that TRUNCATE
does not save the changes in to the Log file. Also you can't use a WHERE
clause with TRUNCATE
AS to why you can run this in SSMS but not via your Application. I really can't see this happening. The FK constraint would still throw an error regardless of where the transaction originated from.
This, at least for me, will make Visual Studio Code open a new Bash window as an external terminal.
If you want the integrated environment you need to point to the sh.exe
file inside the bin
folder of your Git installation.
So the configuration should say C:\\<my-git-install>\\bin\\sh.exe
.
Try this
http://robots.thoughtbot.com/designing-for-ios-blending-modes
or
- (void)viewDidLoad
{
[super viewDidLoad];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 30, 300, 50)];
label.numberOfLines = 0;
label.font = [UIFont systemFontOfSize:13];
label.text = @"These checkmarks use the same gray checkmark image with a tintColor applied to the image view";
[self.view addSubview:label];
[self _createImageViewAtY:100 color:[UIColor purpleColor]];
}
- (void)_createImageViewAtY:(int)y color:(UIColor *)color {
UIImage *image = [[UIImage imageNamed:@"gray checkmark.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
CGRect frame = imageView.frame;
frame.origin.x = 100;
frame.origin.y = y;
imageView.frame = frame;
if (color)
imageView.tintColor = color;
[self.view addSubview:imageView];
}
I just want to add that orderby is way more useful.
Why? Because I can do this:
Dim thisAccountBalances = account.DictOfBalances.Values.ToList
thisAccountBalances.ForEach(Sub(x) x.computeBalanceOtherFactors())
thisAccountBalances=thisAccountBalances.OrderBy(Function(x) x.TotalBalance).tolist
listOfBalances.AddRange(thisAccountBalances)
Why complicated comparer? Just sort based on a field. Here I am sorting based on TotalBalance.
Very easy.
I can't do that with sort. I wonder why. Do fine with orderBy.
As for speed it's always O(n).
Comment space too small, so here is some more information for you on the use of static final
. As I said in my comment to the Andrzej's answer, only primitive and String
are compiled directly into the code as literals. To demonstrate this, try the following:
You can see this in action by creating three classes (in separate files):
public class DisplayValue {
private String value;
public DisplayValue(String value) {
this.value = value;
}
public String toString() {
return value;
}
}
public class Constants {
public static final int INT_VALUE = 0;
public static final DisplayValue VALUE = new DisplayValue("A");
}
public class Test {
public static void main(String[] args) {
System.out.println("Int = " + Constants.INT_VALUE);
System.out.println("Value = " + Constants.VALUE);
}
}
Compile these and run Test, which prints:
Int = 0
Value = A
Now, change Constants
to have a different value for each and just compile class Constants
. When you execute Test
again (without recompiling the class file) it still prints the old value for INT_VALUE
but not VALUE
. For example:
public class Constants {
public static final int INT_VALUE = 2;
public static final DisplayValue VALUE = new DisplayValue("X");
}
Run Test without recompiling Test.java
:
Int = 0
Value = X
Note that any other type used with static final
is kept as a reference.
Similar to C/C++ #if
/#endif
, a constant literal or one defined through static final
with primitives, used in a regular Java if
condition and evaluates to false
will cause the compiler to strip the byte code for the statements within the if
block (they will not be generated).
private static final boolean DEBUG = false;
if (DEBUG) {
...code here...
}
The code at "...code here..." would not be compiled into the byte code. But if you changed DEBUG
to true
then it would be.
panel.setStyle("-fx-background-color: #FFFFFF;");
When you do self.button = Button(...).grid(...)
, what gets assigned to self.button
is the result of the grid()
command, not a reference to the Button
object created.
You need to assign your self.button
variable before packing/griding it.
It should look something like this:
self.button = Button(self,text="Click Me",command=self.color_change,bg="blue")
self.button.grid(row = 2, column = 2, sticky = W)
Try using "uname". For example, in Linux: "uname -a".
According to the manual page, uname conforms to SVr4 and POSIX, so it should be available on Mac OS X and Cygwin too, but I can't confirm that.
BTW: $OSTYPE is also set to linux-gnu
here :)
There is no maximum since Ruby 2.4, as Bignum and Fixnum got unified into Integer. see Feature #12005

=> true
> 1.is_a? Bignum
(irb):314: warning: constant ::Bignum is deprecated

There won't be any overflow, what would happen is an out of memory.
Every time you call itr2.next() you are getting a distinct value. Not the same value. You should only call this once in the loop.
Iterator<String> itr2 = keys.iterator();
while(itr2.hasNext()){
String v = itr2.next();
System.out.println("Key: "+v+" ,value: "+m.get(v));
}
The only viable solution in my opinion is to use
ID INT IDENTITY(1,1)
column to get SQL Server to handle the automatic increment of your numeric valueSo try this:
CREATE TABLE dbo.tblUsers
(ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
UserID AS 'UID' + RIGHT('00000000' + CAST(ID AS VARCHAR(8)), 8) PERSISTED,
.... your other columns here....
)
Now, every time you insert a row into tblUsers
without specifying values for ID
or UserID
:
INSERT INTO dbo.tblUsersCol1, Col2, ..., ColN)
VALUES (Val1, Val2, ....., ValN)
then SQL Server will automatically and safely increase your ID
value, and UserID
will contain values like UID00000001
, UID00000002
,...... and so on - automatically, safely, reliably, no duplicates.
Update: the column UserID
is computed - but it still OF COURSE has a data type, as a quick peek into the Object Explorer reveals:
namespace ReverseString
{
class Program
{
static void Main(string[] args)
{
string stat = "This is an example of code" +
"This code has written in C#\n\n";
Console.Write(stat);
char[] myArrayofChar = stat.ToCharArray();
Array.Reverse(myArrayofChar);
foreach (char myNewChar in myArrayofChar)
Console.Write(myNewChar); // You just need to write the function
// Write instead of WriteLine
Console.ReadKey();
}
}
}
This is the output:
#C ni nettirw sah edoc sihTedoc fo elpmaxe na si sihT
Well, you're getting a java.lang.NoClassDefFoundError
. In your pom.xml
, hibernate-core
version is 3.3.2.GA
and declared after hibernate-entitymanager
, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final
from hibernate-entitymanager
.
You're using spring-boot
as parent, so no need to declare version of some dependencies, since they are managed by spring-boot
.
Also, hibernate-commons-annotations
is inherited from hibernate-entitymanager
and hibernate-annotations
is an old version of hibernate-commons-annotations
, you can remove both.
Finally, your pom.xml
can look like this:

Logically speaking,we're actually talking about the same thing. But I think a simple metaphor would be helpful to solve this dilemma.
If the metaphors can be called various connection point we can equate them to plug points on a wall. In this case we can consider parameters and arguments as follows;
Parameters are the sockets of the plug-point which may take various different shapes. But only certain types of plugs fit them.
Arguments will be the actual plugs that would be plugged into the plug points/sockets to activate certain equipments.
The answer is not efficiency. Non-reentrant mutexes lead to better code.
Example: A::foo() acquires the lock. It then calls B::bar(). This worked fine when you wrote it. But sometime later someone changes B::bar() to call A::baz(), which also acquires the lock.
Well, if you don't have recursive mutexes, this deadlocks. If you do have them, it runs, but it may break. A::foo() may have left the object in an inconsistent state before calling bar(), on the assumption that baz() couldn't get run because it also acquires the mutex. But it probably shouldn't run! The person who wrote A::foo() assumed that nobody could call A::baz() at the same time - that's the entire reason that both of those methods acquired the lock.
The right mental model for using mutexes: The mutex protects an invariant. When the mutex is held, the invariant may change, but before releasing the mutex, the invariant is re-established. Reentrant locks are dangerous because the second time you acquire the lock you can't be sure the invariant is true any more.
If you are happy with reentrant locks, it is only because you have not had to debug a problem like this before. Java has non-reentrant locks these days in java.util.concurrent.locks, by the way.
foo.GetColumnValues(dm.mainColumn, typeof(int));

Or using generics:

foo.GetColumnValues<string>(dm.mainColumn);
cp -R t1/ t2
The trailing slash on the source directory changes the semantics slightly, so it copies the contents but not the directory itself. It also avoids the problems with globbing and invisible files that Bertrand's answer has (copying t1/*
misses invisible files, copying `t1/* t1/.*' copies t1/. and t1/.., which you don't want).
Did you try using t.Text
?
The tricky part is a regex that includes a dash as one of the valid characters in a character class. The dash has to come immediately after the start for a (normal) character class and immediately after the caret for a negated character class. If you need a close square bracket too, then you need the close square bracket followed by the dash. Mercifully, you only need dash, hence the notation chosen.

"MyString"
is in both cases a string literal and in both cases the string is unmodifiable.
function("MyString");
passes the address of a string literal to function

(This answer is from years ago, when it was the best answer. There is now a better answer below this. I haven't kept up with node.js, and I cannot delete this answer because it is marked "correct on this question". If you are thinking of down clicking, what do you want me to do?)
The key is to use the data
and end
events of a Readable Stream. Listen to these events:
stream.on('data', (chunk) => { ... });
stream.on('end', () => { ... });
When you receive the data
event, add the new chunk of data to a Buffer created to collect the data.
When you receive the end
event, convert the completed Buffer into a string, if necessary. Then do what you need to do with it.
ALTER TABLE table_name ALTER COLUMN id SET DEFAULT uuid_in((md5((random())::text))::cstring);
After reading @ZuzEL's answer, i used the above code as the default value of the column id and it's working fine.
I found very in-depth videos which cover $watch
, $apply
, $digest
and digest cycles in:
AngularJS - Understanding Watcher, $watch, $watchGroup, $watchCollection, ng-change
AngularJS - Understanding digest cycle (digest phase or digest process or digest loop)
AngularJS Tutorial - Understanding $apply and $digest (in depth)
Following are a couple of slides used in those videos to explain the concepts (just in case, if the above links are removed/not working).
In the above image, "$scope.c" is not being watched as it is not used in any of the data bindings (in markup). The other two ($scope.a
and $scope.b
) will be watched.
From the above image: Based on the respective browser event, AngularJS captures the event, performs digest cycle (goes through all the watches for changes), execute watch functions and update the DOM. If not browser events, the digest cycle can be manually triggered using $apply
or $digest
.
More about $apply
and $digest
:
Classes (or rather their instances) are for representing things. Classes are used to define the operations supported by a particular class of objects (its instances). If your application needs to keep track of people, then Person
is probably a class; the instances of this class represent particular people you are tracking.
Functions are for calculating things. They receive inputs and produce an output and/or have effects.
Classes and functions aren't really alternatives, as they're not for the same things. It doesn't really make sense to consider making a class to "calculate the age of a person given his/her birthday year and the current year". You may or may not have classes to represent any of the concepts of Person
, Age
, Year
, and/or Birthday
. But even if Age
is a class, it shouldn't be thought of as calculating a person's age; rather the calculation of a person's age results in an instance of the Age
class.
If you are modelling people in your application and you have a Person
class, it may make sense to make the age calculation be a method of the Person
class. A method is basically a function which is defined as part of a class; this is how you "define the operations supported by a particular class of objects" as I mentioned earlier.
So you could create a method on your person class for calculating the age of the person (it would probably retrieve the birthday year from the person object and receive the current year as a parameter). But the calculation is still done by a function (just a function that happens to be a method on a class).
Or you could simply create a stand-alone function that receives arguments (either a person object from which to retrieve a birth year, or simply the birth year itself). As you note, this is much simpler if you don't already have a class where this method naturally belongs! You should never create a class simply to hold an operation; if that's all there is to the class then the operation should just be a stand-alone function.
Efficiency aside, I rarely find myself wishing for declarative collection creation outside of unit tests. I do believe that the double brace syntax is very readable.
Another way to achieve the declarative construction of lists specifically is to use Arrays.asList(T ...)
like so:
List<String> aList = Arrays.asList("vanilla", "strawberry", "chocolate");
The limitation of this approach is of course that you cannot control the specific type of list to be generated.
Use the compareTo
method of BigDecimal :
public int compareTo(BigDecimal val) Compares this BigDecimal with the specified BigDecimal.
Returns: -1, 0, or 1 as this BigDecimal is numerically less than, equal to, or greater than val.
I solved the same problem by adding text-indent to the nested list.
<h4>A nested List:</h4>
<ul>
<li>Coffee</li>
<li>Tea
<ul id="list2">
<li>Black tea</li>
<li>Green tea</li>
</ul>
</li>
<li>Milk</li>
</ul>
#list2
{
text-indent:50px;
}
The following shell command should do what you want:
git log --all --not $(git rev-list --no-walk --exclude=refs/heads/mybranch --all)
If you have mybranch
checked out, the above command won't work. That's because the commits on mybranch
are also reachable by HEAD
, so Git doesn't consider the commits to be unique to mybranch
. To get it to work when mybranch
is checked out, you must also add an exclude for HEAD
:
git log --all --not $(git rev-list --no-walk \
--exclude=refs/heads/mybranch \
--exclude=HEAD \
--all)
However, you should not exclude HEAD
unless the mybranch
is checked out, otherwise you risk showing commits that are not exclusive to mybranch
.
Similarly, if you have a remote branch named origin/mybranch
that corresponds to the local mybranch
branch, you'll have to exclude it:
git log --all --not $(git rev-list --no-walk \
--exclude=refs/heads/mybranch \
--exclude=refs/remotes/origin/mybranch \
--all)
And if the remote branch is the default branch for the remote repository (usually only true for origin/master
), you'll have to exclude origin/HEAD
as well:
git log --all --not $(git rev-list --no-walk \
--exclude=refs/heads/mybranch \
--exclude=refs/remotes/origin/mybranch \
--exclude=refs/remotes/origin/HEAD \
--all)
If you have the branch checked out, and there's a remote branch, and the remote branch is the default for the remote repository, then you end up excluding a lot:
git log --all --not $(git rev-list --no-walk \
--exclude=refs/heads/mybranch \
--exclude=HEAD
--exclude=refs/remotes/origin/mybranch \
--exclude=refs/remotes/origin/HEAD \
--all)
The git rev-list
command is a low-level (plumbing) command that walks the given revisions and dumps the SHA1 identifiers encountered. Think of it as equivalent to git log
except it only shows the SHA1—no log message, no author name, no timestamp, none of that "fancy" stuff.
The --no-walk
option, as the name implies, prevents git rev-list
from walking the ancestry chain. So if you type git rev-list --no-walk mybranch
it will only print one SHA1 identifier: the identifier of the tip commit of the mybranch
branch.
The --exclude=refs/heads/mybranch --all
arguments tell git rev-list
to start from each reference except for refs/heads/mybranch
.
So, when you run git rev-list --no-walk --exclude=refs/heads/mybranch --all
, Git prints the SHA1 identifier of the tip commit of each ref except for refs/heads/mybranch
. These commits and their ancestors are the commits you are not interested in—these are the commits you do not want to see.
The other commits are the ones you want to see, so we collect the output of git rev-list --no-walk --exclude=refs/heads/mybranch --all
and tell Git to show everything but those commits and their ancestors.
The --no-walk
argument is necessary for large repositories (and is an optimization for small repositories): Without it, Git would have to print, and the shell would have to collect (and store in memory) many more commit identifiers than necessary. With a large repository, the number of collected commits could easily exceed the shell's command-line argument limit.
I would have expected the following to work:
git log --all --not --exclude=refs/heads/mybranch --all
but it does not. I'm guessing this is a bug in Git, but maybe it's intentional.
You can use the $set syntax if you want to set the value of a document to an arbitrary value. This will either update the value if the attribute already exists on the document or create it if it doesn't. If you need to set a single value in a dictionary like you describe, you can use the dot notation to access child values.
If p is the object retrieved:
existing = p['d']['a']
For pymongo versions < 3.0
db.ProductData.update({
'_id': p['_id']
},{
'$set': {
'd.a': existing + 1
}
}, upsert=False, multi=False)
For pymongo versions >= 3.0
db.ProductData.update_one({
'_id': p['_id']
},{
'$set': {
'd.a': existing + 1
}
}, upsert=False)
However if you just need to increment the value, this approach could introduce issues when multiple requests could be running concurrently. Instead you should use the $inc syntax:
For pymongo versions < 3.0:
db.ProductData.update({
'_id': p['_id']
},{
'$inc': {
'd.a': 1
}
}, upsert=False, multi=False)
For pymongo versions >= 3.0:
db.ProductData.update_one({
'_id': p['_id']
},{
'$inc': {
'd.a': 1
}
}, upsert=False)
This ensures your increments will always happen.
For a single color line use:
list.setDivider(new ColorDrawable(0x99F10529)); //0xAARRGGBB
list.setDividerHeight(1);
It's important that DividerHeight is set after the divider, else you won't get anything.
td.description {vertical-align: top;}
where description
is the class name of the td
with that text in it
td.description {_x000D_
vertical-align: top;_x000D_

_x000D_
<td class="description">Description</td>
_x000D_
OR inline (yuk!)
<td style="vertical-align: top;">Description</td>

In JavaScript 1.8.5, Object.getOwnPropertyNames
returns an array of all properties found directly upon a given object.
Object.getOwnPropertyNames ( obj )
and another method Object.keys
, which returns an array containing the names of all of the given object's own enumerable properties.
Object.keys( obj )
I used forEach
to list values and keys in obj, same as for (var key in obj) ..
Object.keys(obj).forEach(function (key) {
console.log( key , obj[key] );
});
This all are new features in ECMAScript , the mothods getOwnPropertyNames
, keys
won't supports old browser's.

In my fairly complex scenario the accepted answer for how to do this in Chrome doesn't work for me. You may want to try the Firefox debugger instead (part of the Firefox developer tools), which shows all of the 'Sources', including those that are part of an iFrame
Try Collections.shuffle(list).If usage of this method is barred for solving the problem, then one can look at the actual implementation.
A one liner:

Been a while since I was in ASP land, but iirc there's a couple of ways:
try catch finally
can be reasonably simulated in VBS (good article here here) and there's an event called class_terminate
you can watch and catch exceptions globally in. Then there's the possibility of changing your scripting language...
Click Search --> Replace --> Find What: \0 Replace with: "empty" Search mode: Extended --> Replace all
With your example:
<input type="checkbox" id="c2" name="c2" value="DE039230952"/>
Replace $$ with document.querySelectorAll in the examples:
$$('input') //Every input
$$('[id]') //Every element with id
$$('[id="c2"]') //Every element with id="c2"
$$('input,[id]') //Every input + every element with id
$$('input[id]') //Every input including id
$$('input[id="c2"]') //Every input including id="c2"
$$('input#c2') //Every input including id="c2" (same as above)
$$('input#c2[value="DE039230952"]') //Every input including id="c2" and value="DE039230952"
$$('input#c2[value^="DE039"]') //Every input including id="c2" and value has content starting with DE039
$$('input#c2[value$="0952"]') //Every input including id="c2" and value has content ending with 0952
$$('input#c2[value*="39230"]') //Every input including id="c2" and value has content including 39230
Use the examples directly with:
const $$ = document.querySelectorAll.bind(document);
Some additions:
$$(.) //The same as $([class])
$$(div > input) //div is parent tag to input
document.querySelector() //equals to $$()[0] or $()
My problem was coused by not displayed UTF symbol. I copy the link from the browser (in my case it was an nginx track) and got the following in clipboard:

SOLVED - I had this exact problem. The fix, for me, was to up the disk quota for IUSR on the IIS server. In this instance, we have a catalog app with images of items and such. The upload quota for the "Anonymous Web User" was set to 100MB, which is the default for this particular hosting company's IIS servers. I upped it to 400MB and was able to upload images without error.
This might not be your issue, but if it is, it's an easy fix.
This is a shell convention that tells the shell which program can execute the script.
#!/usr/bin/env python

What if one of the values is negative? Wouldn't a better idea be:
double NextDouble(double min, double max)
{
if (min >= max)
throw new ArgumentOutOfRangeException();
return random.NextDouble() * (Math.Abs(max-min)) + min;
}
Indeed, the 9th byte indicates the check state of the button, but the answers above don't take into account the checkbox which enables manual configuration. This check state value is also present in this ninth byte. The real answer should thus be:
Byte value
00001001 = Manual proxy is checked
00000101 = Use automatic configuration script is checked
00000011 = Automatically detect settings is checked
When multiple checkboxes are checked, the value of the 9th byte is the result of the bitwise OR operation on the values for which the checkbox is checked.
Since there were no exact answers to my question, I made some investigation why my code doesn't work when there are other solutions that works, and decided to post what I found to complete the subject.
As it turns out:
"ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user." sshpass manpage
which answers the question, why the pipes don't work in this case. The obvious solution was to create conditions so that ssh
"thought" that it is run in the regular terminal and since it may be accomplished by simple posix
functions, it is beyond what simple bash
offers.
I would point a beginner to the Wiki article on the Main function, then supplement it with this.
Java only starts running a program with the specific public static void main(String[] args)
signature, and one can think of a signature like their own name - it's how Java can tell the difference between someone else's main()
and the one true main()
.
String[] args
is a collection of String
s, separated by a space, which can be typed into the program on the terminal. More times than not, the beginner isn't going to use this variable, but it's always there just in case.
Using LaTeX syntax directly in a Markdown cell works for me. I'm using Jypiter 4.4.0.
I don't have to use %%latex
magic command, I insist, simply a markdown cell:
\begin{align}
\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\
\nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
\nabla \cdot \vec{\mathbf{B}} & = 0
\end{align}
Renders to:
Since you return to the client just String
and its content type == 'text/plain'
, there is no any chance for default converters to determine how to convert String
response to the FFSampleResponseHttp
object.
The simple way to fix it:
expected-response-type
from <int-http:outbound-gateway>
replyChannel1
<json-to-object-transformer>
Otherwise you should write your own HttpMessageConverter
to convert the String to the appropriate object.
To make it work with MappingJackson2HttpMessageConverter
(one of default converters) and your expected-response-type
, you should send your reply with content type = 'application/json'
.
If there is a need, just add <header-enricher>
after your <service-activator>
and before sending a reply to the <int-http:inbound-gateway>
.
So, it's up to you which solution to select, but your current state doesn't work, because of inconsistency with default configuration.
UPDATE
OK. Since you changed your server to return FfSampleResponseHttp
object as HTTP response, not String, just add contentType = 'application/json'
header before sending the response for the HTTP and MappingJackson2HttpMessageConverter
will do the stuff for you - your object will be converted to JSON and with correct contentType
header.
From client side you should come back to the expected-response-type="com.mycompany.MyChannel.model.FFSampleResponseHttp"
and MappingJackson2HttpMessageConverter
should do the stuff for you again.
Of course you should remove <json-to-object-transformer>
from you message flow after <int-http:outbound-gateway>
.
from functools import partial as p

is one way you could do it ... your teacher probably knows a much less complicated way that was probably covered in class
Not sure it works in tsql, but some platforms have to_char()
:
test=#select to_char(131213211653.78, '9,999,999,999,999.99');
to_char
-----------------------
131,213,211,653.78
test=# select to_char(131213211653.78, '9G999G999G999G999D99');
to_char
-----------------------
131,213,211,653.78
test=# select to_char(485, 'RN');
to_char
-----------------
CDLXXXV
As the example suggests, the format's length needs to match that of the number for best results, so you might want to wrap it in a function (e.g. number_format()) if needed.
Converting to money works too, as point out by the other repliers.
test=# select substring(cast(cast(131213211653.78 as money) as varchar) from 2);
substring
--------------------
131,213,211,653.78
$("#myselect option:contains('YourTextHere')").val();
will return the value of the first option containing your text description. Tested this and works.
All strings meant for humans should use u"".
I found that the following mindset helps a lot when dealing with Python strings: All Python manifest strings should use the u""
syntax. The ""
syntax is for byte arrays, only.
Before the bashing begins, let me explain. Most Python programs start out with using ""
for strings. But then they need to support documentation off the Internet, so they start using "".decode
and all of a sudden they are getting exceptions everywhere about decoding this and that - all because of the use of ""
for strings. In this case, Unicode does act like a virus and will wreak havoc.
But, if you follow my rule, you won't have this infection (because you will already be infected).
You can swap out instances of NULL with a different value to sort them first (like 0 or -1) or last (a large number or a letter)...
SELECT field1, IF(field2 IS NULL, 9999, field2) as ordered_field2
FROM tablename
WHERE visible = 1
ORDER BY ordered_field2 ASC, id DESC
Most answers require the use of an asynchroneous timeout, which causes an annoying blink.
But I came up with this one, which works smoothly because it is synchroneous:
var p = el.parentNode,
s = el.nextSibling;
p.removeChild(el);
p.insertBefore(el, s);
Cloning from a local repo will not work with git clone & git fetch: a lot of branches/tags will remain unfetched.

You can't do this. A File
is just an abstract way to refer to a file in the file system. It doesn't contain any of the file contents itself.
If you're trying to create an in-memory file that can be referred to using a File

Please note this doesn't solve the cookie sharing process, as in general this is bad practice.

Visual Studio Code: Version 1.14.2 (1.14.2)
At default setting, you can see this:
// Columns at which to show vertical rulers
"editor.rulers": [],
This means the empty array won't show the vertical rulers.
At right window "user setting", add the following:
"editor.rulers": [140]
Save the file, and you will see the rulers.
Old thread but thought I'd just add that the reason developers use this construct is not to create a dead link, but because javascript URLs for some reason do not pass references to the active html element correctly.
e.g. handler_function(this.id)
works as onClick
but not as a javascript URL.
Thus it's a choice between writing pedantically standards-compliant code that involves you in having to manually adjust the call for each hyperlink, or slightly non-standard code which can be written once and used everywhere.
There's no need to use lambdas and/or give radix
parameter to parseInt
, just use parseFloat
or Number
instead.
Reasons:
It's working:
var src = "1,2,5,4,3";
var ids = src.split(',').map(parseFloat); // [1, 2, 5, 4, 3]
var obj = {1: ..., 3: ..., 4: ..., 7: ...};
var keys= Object.keys(obj); // ["1", "3", "4", "7"]
var ids = keys.map(parseFloat); // [1, 3, 4, 7]
var arr = ["1", 5, "7", 11];
var ints= arr.map(parseFloat); // [1, 5, 7, 11]
ints[1] === "5" // false
ints[1] === 5 // true
ints[2] === "7" // false
ints[2] === 7 // true
It's shorter.
It's a tiny bit quickier and takes advantage of cache, when parseInt
-approach - doesn't:
// execution time measure function
// keep it simple, yeah?
> var f = (function (arr, c, n, m) {
var i,t,m,s=n();
for(i=0;i++<c;)t=arr.map(m);
return n()-s
}).bind(null, "2,4,6,8,0,9,7,5,3,1".split(','), 1000000, Date.now);

Consider the following servlet conf:
<servlet>
<servlet-name>NewServlet</servlet-name>
<servlet-class>NewServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>NewServlet</servlet-name>
<url-pattern>/NewServlet/*</url-pattern>
</servlet-mapping>
Now, when I hit the URL http://localhost:8084/JSPTemp1/NewServlet/jhi
, it will invoke NewServlet
as it is mapped with the pattern described above.
Here:
getRequestURI() = /JSPTemp1/NewServlet/jhi
getPathInfo() = /jhi
We have those ones:
getPathInfo()
returns
a String, decoded by the web container, specifying extra path information that comes after the servlet path but before the query string in the request URL; or null if the URL does not have any extra path information
getRequestURI()
returns
a String containing the part of the URL from the protocol name up to the query string
The hyphen is usually a normal character in regular expressions. Only if it’s in a character class and between two other characters does it take a special meaning.
Thus:
[-]
matches a hyphen.[abc-]
matches a
, b
, c
or a hyphen.[-abc]
matches a
, b
, c
or a hyphen.[ab-d]
matches a
, b
, c
or d
(only here the hyphen denotes a character range).Windows Firewall could cause this exception, try to disable it or add a rule for port or even program (java)
Using the scatter
method of the matplotlib.pyplot
module should work (at least with matplotlib 1.2.1 with Python 2.7.5), as in the example code below. Also, if you are using scatter plots, use scatterpoints=1
rather than numpoints=1
in the legend call to have only one point for each legend entry.
In the code below I've used random values rather than plotting the same range over and over, making all the plots visible (i.e. not overlapping each other).

To plot a scatter in 3D, use the plot
method, as the legend does not support Patch3DCollection
as is returned by the scatter
method of an Axes3D
instance. To specify the markerstyle you can include this as a positional argument in the method call, as seen in the example below. Optionally one can include argument to both the linestyle
and marker
parameters.
import matplotlib.pyplot as plt
from numpy.random import random
from mpl_toolkits.mplot3d import Axes3D
colors=['b', 'c', 'y', 'm', 'r']
ax = plt.subplot(111, projection='3d')
ax.plot(random(10), random(10), random(10), 'x', color=colors[0], label='Low Outlier')
ax.plot(random(10), random(10), random(10), 'o', color=colors[0], label='LoLo')
ax.plot(random(10), random(10), random(10), 'o', color=colors[1], label='Lo')
ax.plot(random(10), random(10), random(10), 'o', color=colors[2], label='Average')
ax.plot(random(10), random(10), random(10), 'o', color=colors[3], label='Hi')
ax.plot(random(10), random(10), random(10), 'o', color=colors[4], label='HiHi')
ax.plot(random(10), random(10), random(10), 'x', color=colors[4], label='High Outlier')
plt.legend(loc='upper left', numpoints=1, ncol=3, fontsize=8, bbox_to_anchor=(0, 0))

in laravel used decimal column type for migration
$table->decimal('latitude', 10, 8);
$table->decimal('longitude', 11, 8);
for more information see available column type
The option that I tend to use, mostly because it's simple and I don't have to think, is using Write-Output as below. Write-Output will put an EOL marker in the string for you and you can simply output the finished string.
Write-Output $stringThatNeedsEOLMarker | Out-File -FilePath PathToFile -Append
Alternatively, you could also just build the entire string using Write-Output and then push the finished string into Out-File.
Could it be as simple as enclosing your asset in " " and whatever needs quotes on the inside with ' '?
<link rel="stylesheet" media="screen" href="@routes.Assets.at("stylesheets/main.css")">
becomes
<link rel="stylesheet" media="screen" href="@routes.Assets.at('stylesheets/main.css')">
That could be causing some problems with parsing
If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.
Once you put your application online, I believe that this problem should be automatically solved. But i think ini_set()
helps you to change the values in php.ini
during run time.
First day of week (Monday):
SELECT TO_DATE(to_char(sysdate,'YYYY')||'0101','YYYYMMDD') + 7 * to_number(to_char(sysdate,'WW')-1)-1 first_day_week FROM dual;
Last day of week (Sunday):
SELECT TO_DATE(to_char(sysdate,'YYYY')||'0101','YYYYMMDD') + 7 * to_number(to_char(sysdate,'WW')-1)+5 last_day_week FROM dual;
Substituting your date or date field in these formulas will work for you!

Date
is Comparable
& Equatable
(as of Swift 3)This answer complements @Ankit Thakur's answer.
Since Swift 3 the Date
struct (based on the underlying NSDate
class) adopts the Comparable
and Equatable
protocols.
Comparable
requires that Date
implement the operators: <
, <=
, >
, >=
.Equatable
requires that Date
implement the ==
operator.Equatable
allows Date
to use the default implementation of the !=
operator (which is the inverse of the Equatable
==
operator implementation).The following sample code exercises these comparison operators and confirms which comparisons are true with print
statements.
import Foundation
func describeComparison(date1: Date, date2: Date) -> String {
var descriptionArray: [String] = []
if date1 < date2 {
descriptionArray.append("date1 < date2")
}
if date1 <= date2 {
descriptionArray.append("date1 <= date2")
}
if date1 > date2 {
descriptionArray.append("date1 > date2")
}
if date1 >= date2 {
descriptionArray.append("date1 >= date2")
}
if date1 == date2 {
descriptionArray.append("date1 == date2")
}
if date1 != date2 {
descriptionArray.append("date1 != date2")
}
return descriptionArray.joined(separator: ", ")
}
let now = Date()
describeComparison(date1: now, date2: now.addingTimeInterval(1))
// date1 < date2, date1 <= date2, date1 != date2
describeComparison(date1: now, date2: now.addingTimeInterval(-1))
// date1 > date2, date1 >= date2, date1 != date2
describeComparison(date1: now, date2: now)
// date1 <= date2, date1 >= date2, date1 == date2
Try this Javascript (jquery) code. Its an ajax request to an external URL. Use the callback function to fire any code:
<script type="text/javascript">
$(function() {
$('form').submit(function(){
$.post('http://example.com/upload', function() {
window.location = 'http://google.com';
});
return false;
});
});
</script>
Running Ubuntu, I had to do:
sudo apt-get install python-mysqldb
About looping through a hash:
$Q = @{"ONE"="1";"TWO"="2";"THREE"="3"}
$Q.GETENUMERATOR() | % { $_.VALUE }
1
3
2
$Q.GETENUMERATOR() | % { $_.key }
ONE
THREE
TWO
Although it is not Jquery , I use jquery myself but for browser detection I have used the script on this page a few times. It detects all major browsers, and then some. The work is pretty much all done for you.
What everyone is forgeting is explaining WHY this happens.
A Char, is basically an integer, but with a pointer in the ASCII table. All characters have a corresponding integer value as you can clearly see when trying to parse it.
Pranay has clearly a different character set, thats why HIS code doesnt work. the only way is
int val = '1' - '0';
because this looks up the integer value in the table of '0'
which is then the 'base value'
subtracting your number in char format from this will give you the original number.
If your JAR was from a Spring-boot
project and created using the command mvn package spring-boot:repackage
, the above "-cp" method won't work. You will get:
Error: Could not find or load main class your.alternative.class.path
even if you can see the class in the JAR by jar tvf yours.jar
.
In this case, run your alternative class by the following command:
java -cp yours.jar -Dloader.main=your.alternative.class.path org.springframework.boot.loader.PropertiesLauncher
As I understood, the Spring-boot's org.springframework.boot.loader.PropertiesLauncher
class serves as a dispatching entrance class, and the -Dloader.main
parameter tells it what to run.
