You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace); CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession); CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);
(left, upper, right, lower) means two points,
with an 800x600 pixel image, the image's left upper point is (0, 0), the right lower point is (800, 600).
So, for cutting the image half:
from PIL import Image
img = Image.open("ImageName.jpg")
img_left_area = (0, 0, 400, 600)
img_right_area = (400, 0, 800, 600)
img_left = img.crop(img_left_area)
img_right = img.crop(img_right_area)
img_left.show()
img_right.show()
The Python Imaging Library uses a Cartesian pixel coordinate system, with (0,0) in the upper left corner. Note that the coordinates refer to the implied pixel corners; the centre of a pixel addressed as (0, 0) actually lies at (0.5, 0.5).
Coordinates are usually passed to the library as 2-tuples (x, y). Rectangles are represented as 4-tuples, with the upper left corner given first. For example, a rectangle covering all of an 800x600 pixel image is written as (0, 0, 800, 600).
I find it easier to skimage.util.view_as_windows
or `skimage.util.view_as_blocks which also allows you to configure the step
To correct @willsteel solution:
if (landscape){
int start = (tempBitmap.getWidth() - tempBitmap.getHeight()) / 2;
croppedBitmap = Bitmap.createBitmap(tempBitmap, start, 0, tempBitmap.getHeight(), tempBitmap.getHeight(), matrix, true);
} else {
int start = (tempBitmap.getHeight() - tempBitmap.getWidth()) / 2;
croppedBitmap = Bitmap.createBitmap(tempBitmap, 0, start, tempBitmap.getWidth(), tempBitmap.getWidth(), matrix, true);
}
As an alternative solution to the GCD searching, I suggest you to check against a set of standard values. You can find a list on Wikipedia.
first, extract ids from the collection where condition
List<int> indexes_Yes = this.Contenido.Where(x => x.key == 'TEST').Select(x => x.Id).ToList();
second, use "compare" estament to select ids diffent to the selection
List<int> indexes_No = this.Contenido.Where(x => !indexes_Yes.Contains(x.Id)).Select(x => x.Id).ToList();
Obviously you can use x.key != "TEST", but is only a example
Testing for name pointing to None
and name existing are two semantically different operations.
To check if val
is None:
if val is None:
pass # val exists and is None
To check if name exists:
try:
val
except NameError:
pass # val does not exist at all
This article from W3C tells you what they think you should do https://www.w3.org/WAI/GL/wiki/ARIATechnique_usingImgRole_with_aria-label_forCSS-backgroundImage
and has examples here http://mars.dequecloud.com/demo/ImgRole.htm
among which
<a href="http://www.facebook.com">
<span class="fb_logo" role="img" aria-label="Connect via Facebook">
</span>
</a>
Still, if, like in the above example, the element containing the background image is just an empty container, I personally prefer to put the text in there and hide it using CSS; right where you show the image instead:
<a href="http://www.facebook.com"><span class="fb_logo">
Connect via Facebook
</span></a>
.fb_logo {
height: 37px; width: 37px;
background-image: url('../gfx/logo-facebook.svg');
color:transparent; overflow:hidden; /* hide the text */
}
You cannot used the Helper @Html.DropdownListFor
, because the first parameter was not correct, change your helper to:
@Html.DropDownList("accountid", new SelectList(ViewBag.Accounts, "AccountID", "AccountName"))
@Html.DropDownListFor
receive in the first parameters a lambda expression in all overloads and is used to create strongly typed dropdowns.
If your View it's strongly typed to some Model you may change your code using a helper to created a strongly typed dropdownlist, something like
@Html.DropDownListFor(x => x.accountId, new SelectList(ViewBag.Accounts, "AccountID", "AccountName"))
In your case the "Vendor code 17002" is the equivalent of the ORA-12541 error: It's most likely that your listener is down, or has an improper port or service name. From the docs:
ORA-12541: TNS no listener
Cause: Listener for the source repository has not been started.
Action: Start the Listener on the machine where the source repository resides.
just try this one:
1)Share a folder with full permission in your computer
2) in your SQL server : control panel -> administrative tools -> services -> right click on all SQL services
on log on tab should start with your domain administrator
3) in maintenance wizard of sql server place the back up location and folder (\yourcomputername\sharedfoldernam)
I did remote backup on 8 server of sql server 2008 in our company
In Java there isn't Null values for primitive Data types. If you need to check Null use Integer Class instead of primitive type. You don't need to worry about data type difference. Java converts int primitive type data to Integer. When concerning about the memory Integer takes more memory than int. But the difference of memory allocation, nothing to be considered.
In this case you must use Inter instead of int
Try below snippet and see example for more info,
Integer id;
String name;
//Refer this example
Integer val = 0;
`
if (val != null){
System.out.println("value is not null");
}
`
Also you can assign Null as below,
val = null;
Use textcleaner library to remove stopwords from your data.
Follow this link:https://yugantm.github.io/textcleaner/documentation.html#remove_stpwrds
Follow these steps to do so with this library.
pip install textcleaner
After installing:
import textcleaner as tc
data = tc.document(<file_name>)
#you can also pass list of sentences to the document class constructor.
data.remove_stpwrds() #inplace is set to False by default
Use above code to remove the stop-words.
Use the user agent from $_SERVER['HTTP_USER_AGENT']
,
and for simple detection you can use this script:
<?php
//Detect special conditions devices
$iPod = stripos($_SERVER['HTTP_USER_AGENT'],"iPod");
$iPhone = stripos($_SERVER['HTTP_USER_AGENT'],"iPhone");
$iPad = stripos($_SERVER['HTTP_USER_AGENT'],"iPad");
$Android = stripos($_SERVER['HTTP_USER_AGENT'],"Android");
$webOS = stripos($_SERVER['HTTP_USER_AGENT'],"webOS");
//do something with this information
if( $iPod || $iPhone ){
//browser reported as an iPhone/iPod touch -- do something here
}else if($iPad){
//browser reported as an iPad -- do something here
}else if($Android){
//browser reported as an Android device -- do something here
}else if($webOS){
//browser reported as a webOS device -- do something here
}
?>
If you want to know more details of the user device I recommended to use one of the following solutions: http://51degrees.mobi or http://deviceatlas.com
Many languages have variables, which are of a specific type and have a value. Python does not have variables; it has objects, and you use names to refer to these objects.
In other languages, when you say:
a = 1
then a (typically integer) variable changes its contents to the value 1.
In Python,
a = 1
means “use the name a to refer to the object 1”. You can do the following in an interactive Python session:
>>> type(1)
<type 'int'>
The function type
is called with the object 1
; since every object knows its type, it's easy for type
to find out said type and return it.
Likewise, whenever you define a function
def funcname(param1, param2):
the function receives two objects, and names them param1
and param2
, regardless of their types. If you want to make sure the objects received are of a specific type, code your function as if they are of the needed type(s) and catch the exceptions that are thrown if they aren't. The exceptions thrown are typically TypeError
(you used an invalid operation) and AttributeError
(you tried to access an inexistent member (methods are members too) ).
Use "php -l <filename>" (that's an 'L') from the command line to output the syntax error that could be causing PHP to throw the status 500 error. It'll output something like:
PHP Parse error: syntax error, unexpected '}' in <filename> on line 18
The solution worked for me was
ng serve --port 4401
(You can change 4401 to whatever number you want)
Then launch browser -> http://localhost:4401/
Basically, I was having two Applications and with the help of the above approach now I am able to run both of them simultaneously in my development environment.
For me it was missing MySQL PDO, I recompiled my PHP with the --with-pdo-mysql
option, installed it and restarted apache and it was all working
The problem occurred due to the Control validator. Just Add the J Query reference to your web page as follows and then add the Validation Settings in your web.config file to overcome the problem. I too faced the same problem and the below gave the solution to my problem.
Step1:
Step2 :
It will resolve your problem.
You can use find() :
$('#my_id').find('my_class');
Or maybe:
$('#my_id').find('span');
Both methods will word for what you want
var myCheckboxes = new Array();
$("input:checked").each(function() {
data['myCheckboxes[]'].push($(this).val());
});
You are pushing checkboxes to wrong array data['myCheckboxes[]']
instead of myCheckboxes.push
&
) to the beginning of the entry. The abstract version can be:
import numpy as np
myList = [10, 20, 30, 40, 50, 60, 70, 80, 90]
myInt = 10
newList = np.divide(myList, myInt)
I believe the get()
function immediately runs the select query and does not accept ORDER BY
conditions as parameters. I think you'll need to separately declare the conditions, then run the query. Give this a try:
$this->db->from($this->table_name);
$this->db->order_by("name", "asc");
$query = $this->db->get();
return $query->result();
There's also this quick (and somewhat dirty) one-liner:
$linecount=0; $i=0; Get-Content .\BIG_LOG_FILE.txt | %{ Add-Content OUT$i.log "$_"; $linecount++; if ($linecount -eq 3000) {$I++; $linecount=0 } }
You can tweak the number of first lines per batch by changing the hard-coded 3000 value.
I had a such problem too because i was using IMG tag and UL tag.
Try to apply the 'corners' plugin to elements such as $('#mydiv').corner()
, $('#myspan').corner()
, $('#myp').corner()
but NOT for $('#img').corner()
!
This rule is related with adding child DIVs into specified element for emulation round-corner effect. As we know IMG element couldn't have any child elements.
I've solved this by wrapping a needed element within the div and changing IMG to DIV with background: CSS property.
Good luck!
In this code you just need to call this in your button click.
private void list_paired_Devices() {
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
ArrayList<String> devices = new ArrayList<>();
for (BluetoothDevice bt : pairedDevices) {
devices.add(bt.getName() + "\n" + bt.getAddress());
}
ArrayAdapter arrayAdapter = new ArrayAdapter(bluetooth.this, android.R.layout.simple_list_item_1, devices);
emp.setAdapter(arrayAdapter);
}
below works for mysql
update table1 INNER JOIN table2 on table1.col1 = table2.col1
set table1.col1 = table2.col2
You can select the database when connecting with psql. This is handy when using it from a script:
sudo -u postgres psql -c "CREATE SCHEMA test AUTHORIZATION test;" test
Year(Date)
Year()
: Returns the year portion of the date argument.
Date
: Current date only.
Explanation of both of these functions from here.
The 32-bit vs 64-bit difference does become more important when you are interfacing with native libraries. 64-bit Java will not be able to interface with a 32-bit non-Java dll (via JNI)
What about this?
java.sql.Timestamp timestamp = java.sql.Timestamp.valueOf("2007-09-23 10:10:10.0");
When I tried '.* in windows (Notepad ++) it would match everything after first ' until end of last line.
To capture everything until end of that line I typed the following:
'.*?\n
This would only capture everything from ' until end of that line.
You simply need to remove v-bind (:) from selected and required attributes. Like this :-
<template>_x000D_
<select class="form-control" v-model="selected" required @change="changeLocation">_x000D_
<option selected>Choose Province</option>_x000D_
<option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>_x000D_
</select>_x000D_
</template>
_x000D_
You are not binding anything to the vue instance through these attributes thats why it is giving error.
borrowed this shamely from here
Process process = new ProcessBuilder("C:\\PathToExe\\MyExe.exe","param1","param2").start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
System.out.printf("Output of running %s is:", Arrays.toString(args));
while ((line = br.readLine()) != null) {
System.out.println(line);
}

I wrote a function for the FFT in Java: http://www.wikijava.org/wiki/The_Fast_Fourier_Transform_in_Java_%28part_1%29
It's in the Public Domain so you can use those functions everywhere (personal or business projects too). Just cite me in the credits and send me just a link of your work, and you're ok.
It is completely reliable. I've checked its output against the Mathematica's FFT and they were always correct until the 15th decimal digit. I think it's a very good FFT implementation for Java. I wrote it on the J2SE 1.6 version, and tested it on the J2SE 1.5-1.6 version.
If you count the number of instruction (it's a lot much simpler than a perfect computational complexity function estimation) you can clearly see that this version is great even if it's not optimized at all. I'm planning to publish the optimized version if there are enough requests.
Let me know if it was useful, and tell me any comment you like.

This is a listener I wrote to solve the problem: it autodetects if the driver has registered itself and acts accordingly.it
Important: it is meant to be used ONLY when the driver jar is deployed in WEB-INF/lib, not in the Tomcat /lib, as many suggest, so that each application can take care of its own driver and run on a untouched Tomcat. That is the way it should be IMHO.
Just configure the listener in your web.xml before any other and enjoy.
add near the top of web.xml:
<listener>
<listener-class>utils.db.OjdbcDriverRegistrationListener</listener-class>

I have tried a small script in python that goes in a bin folder.... 'gitprompt' file
#!/usr/bin/env python
import subprocess, os
s = os.path.join(os.getcwd(), '.git')
def cut(cmd):

half=0
record = False
for c in cmd:

if half == 1:
record = True
return ret
if (os.path.isdir(s)):
out = subprocess.check_output("git branch",shell=True)
print cut(out)
else:
print "-"
Make it executable and stuff
Then adjust the bash prompt accordingly like :

Guava has a method Ints.asList()
for creating a List<Integer>
backed by an int[]
array. You can use this with Collections.sort to apply the Comparator to the underlying array.
List<Integer> integersList = Ints.asList(arr);
Collections.sort(integersList, Collections.reverseOrder());
Note that the latter is a live list backed by the actual array, so it should be pretty efficient.
If you are using intellij, then try restarting intellij cache
See if it works, it worked for me.

I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).
The only difference would be if you try to reassign it before the end of this very file.
I use ssh to connect to remote server and have python code execute cv2.VideoCapture(0) to capture remote webcam, then encounter this error message:
error: (-215)size.width>0 && size.height>0 in function imshow
Finally, I have to grant access to /dev/video0 (which is my webcam device) with my user account and the error message was gone. Use usermod to add user into group video
usermod -a -G video user
mysqladmin -u root -p password
enter your current

then
enter your new password
Your local branch likely has modifications to it you want to discard. To do this, you'll need to use git reset
to reset the branch head to the last spot that you diverged from the upstream repo's branch. Use git branch -v
to find the sha1 id of the upstream branch, and reset your branch it it using git reset SHA1ID
. Then you should be able to do a git checkout
to discard the changes it left in your directory.
Note: always do this on a backed-up repo. That way you can assure you're self it worked right. Or if it didn't, you have a backup to revert to.
OK, considering that you are using Windows, the most simple way to do that is to use the standard ftp
tool bundled with it. I base the following solution on Windows XP, hoping it'll work as well (or with minor modifications) on other versions.
First of all, you need to create a batch (script) file for the ftp
program, containing instructions for it. Name it as you want, and put into it:
curl -u login:pass ftp.myftpsite.com/iiumlabs* -O
open ftp.myftpsite.com
login
pass
mget *
quit
The first line opens a connection to the ftp server at ftp.myftpsite.com
. The two following lines specify the login, and the password which ftp will ask for (replace login
and pass
with just the login and password, without any keywords). Then, you use mget *
to get all files. Instead of the *
, you can use any wildcard. Finally, you use quit
to close the ftp
program without interactive prompt.
If you needed to enter some directory first, add a cd
command before mget
. It should be pretty straightforward.
Finally, write that file and run ftp
like this:
ftp -i -s:yourscript
where -i
disables interactivity (asking before downloading files), and -s
specifies path to the script you created.
Sadly, file transfer over SSH is not natively supported in Windows. But for that case, you'd probably want to use PuTTy tools anyway. The one of particular interest for this case would be pscp
which is practically the PuTTy counter-part of the openssh scp
command.
The syntax is similar to copy
command, and it supports wildcards:
pscp -batch [email protected]:iiumlabs* .
If you authenticate using a key file, you should pass it using -i path-to-key-file
. If you use password, -pw pass
. It can also reuse sessions saved using PuTTy, using the load -load your-session-name
argument.
str(object)
will do the trick.
If you want to alter the way object is stringified, define __str__(self)
method for object's class. Such method has to return str or unicode object.
Greenkeeper if you're using Github. https://greenkeeper.io/
It's a Github integration and incredibly easy to set things up. When installed, it automatically creates pull requests in repositories you specify (or all if wanted) and keeps your code always up-to-date, without forcing you to do anything manually. PRs should then trigger a build on a CI service and depending on a successful or failed check you can keep figuring out what's triggering the issue or when CI passes simply merge the PR.
At the bottom, you can see that the first build failed at first and after a commit ("upgrade to node v6.9") the tests pass so I could finally merge the PR. Comes with a lot of emoji, too.
Another alternative would be https://dependencyci.com/, however I didn't test it intensively. After a first look Greenkeeper looks better in general IMO and has better integration.
Check out the "encoding/binary" package. Particularly the Read and Write functions:
binary.Write(a, binary.LittleEndian, myInt)
https://dev.mysql.com/doc/refman/8.0/en/lock-tables.html
The correct way to use LOCK TABLES and UNLOCK TABLES with transactional tables, such as InnoDB tables, is to begin a transaction with SET autocommit = 0 (not START TRANSACTION) followed by LOCK TABLES, and to not call UNLOCK TABLES until you commit the transaction explicitly. For example, if you need to write to table t1 and read from table t2, you can do this:
SET autocommit=0;
LOCK TABLES t1 WRITE, t2 READ, ...;... do something with tables t1 and t2 here ...
COMMIT;
UNLOCK TABLES;
Note: with Git 2.14.x/2.15 (Q3 2017), the git rebase
message in case of conflicts will be clearer.

rebase
: make resolve message clearer for inexperienced users
Before:
When you have resolved this problem, run "git rebase --continue".
If you prefer to skip this patch, run "git rebase --skip" instead.
To check out the original branch and stop rebasing, run "git rebase --abort"
After:
Resolve all conflicts manually,
mark them as resolved with git add/rm <conflicted_files>
then run "git rebase --continue".
You can instead skip this commit: run "git rebase --skip".
To abort and get back to the state before "git rebase", run "git rebase --abort".')
The git UI can be improved by addressing the error messages to those they help: inexperienced and casual git users.
To this intent, it is helpful to make sure the terms used in those messages can be understood by this segment of users, and that they guide them to resolve the problem.In particular, failure to apply a patch during a git rebase is a common problem that can be very destabilizing for the inexperienced user.
It is important to lead them toward the resolution of the conflict (which is a 3-steps process, thus complex) and reassure them that they can escape a situation they can't handle with "--abort
".
This commit answer those two points by detailing the resolution process and by avoiding cryptic git linguo.
myfun(*some_tuple)
does exactly what you request. The *
operator simply unpacks the tuple (or any iterable) and passes them as the positional arguments to the function. Read more about unpacking arguments.
dropdownlist.Items.Insert(0, new Listitem("--Select One--", "0");
As per my suggestion if you are doing filter or searching
then you should go with :
$results = User::query();
$results->when($request->that, function ($q) use ($request) {
$q->where('that', $request->that);
});
$results->when($request->this, function ($q) use ($request) {
$q->where('this', $request->that);
});
$results->when($request->this_too, function ($q) use ($request) {
$q->where('this_too', $request->that);
});
$results->get();
I got this error after change a loop in my program, let`s see:
for ...
for ...
x_batch.append(one_hot(int_word, vocab_size))
y_batch.append(one_hot(int_nb, vocab_size, value))
...
...
if ...
x_batch = np.asarray(x_batch)
y_batch = np.asarray(y_batch)
...
In fact, I was reusing the variable and forgot to reset them inside the external loop, like the comment of John Lyon:
for ...
x_batch = []
y_batch = []
for ...
x_batch.append(one_hot(int_word, vocab_size))
y_batch.append(one_hot(int_nb, vocab_size, value))
...
...
if ...
x_batch = np.asarray(x_batch)
y_batch = np.asarray(y_batch)
...
Then, check if you are using np.asarray() or something like that.
Try using the TimeRange object in C# to complete your goal.
TimeRange timeRange = new TimeRange();

bool IsNowInTheRange = timeRange.IsIn(DateTime.Now.TimeOfDay);
Console.Write(IsNowInTheRange);
You most likely have your virtual machine’s networking set to NAT. If you set your networking to Bridged you should be able to access your host machine by its hostname. For example, if your hostname is “jsmith-Precision-7510” and you want to open http://localhost:3000/, you will be able to view that page at http://jsmith-Precision-7510:3000/.
To find your hostname, open a terminal/console and then run the command hostname
. Your hostname will be outputted on the next line.
See the VirtualBox documentation for instructions on how to set your networking setttings to Bridged.
You can specify esversion:6 inside jshint options object. Please see the image. I am using grunt-contrib-jshint plugin.
Try this:

Think of it like an archive. MyDB.Bak contains MyDB.mdf and MyDB.ldf.
Restore with Move to say HerDB basically grabs MyDB.mdf (and ldf) from the back up, and copies them as HerDB.mdf and ldf.
So if you already had a MyDb on the server instance you are restoring to it wouldn't be touched.
JDK's can be downloaded from here as zip file nor .exe http://installbuilder.bitrock.com/java/
For a web application, to get the current web application root directory, generally call by web page for the current incoming request:
HttpContext.Current.Server.MapPath();
System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath;
There is a good solution to this issue:
import com.fasterxml.jackson.databind.ObjectMapper;
ObjectMapper objectMapper = new ObjectMapper();
***DTO premierDriverInfoDTO = objectMapper.convertValue(jsonString, ***DTO.class);
Map<String, String> map = objectMapper.convertValue(jsonString, Map.class);
Why did this issue occur? I guess you didn't specify the specific type when converting a string to the object, which is a class with a generic type, such as, User <T>.
Maybe there is another way to solve it, using Gson instead of ObjectMapper. (or see here Deserializing Generic Types with GSON)
Gson gson = new GsonBuilder().create();
Type type = new TypeToken<BaseResponseDTO<List<PaymentSummaryDTO>>>(){}.getType();
BaseResponseDTO<List<PaymentSummaryDTO>> results = gson.fromJson(jsonString, type);
BigDecimal revenue = results.getResult().get(0).getRevenue();
For Java:
X, exactly n times: X{n}
X, at least n times: X{n,}
X, at least n but not more than m times: X{n,m}
To store the third line into a variable, use below syntax:
variable=`echo "$1" | sed '3q;d' urfile`
To store the changed line into a variable, use below syntax:
variable=echo 'overflow' | sed -e "s/over/"OVER"/g"
output:OVERflow
You've told jQuery to expect a JSONP response, which is why jQuery has added the callback=jQuery16406345664265099913_1319854793396&_=1319854793399
part to the URL (you can see this in your dump of the request).
What you're returning is JSON, not JSONP. Your response looks like
{"red" : "#f00"}
and jQuery is expecting something like this:
jQuery16406345664265099913_1319854793396({"red" : "#f00"})
If you actually need to use JSONP to get around the same origin policy, then the server serving colors.json
needs to be able to actually return a JSONP response.
If the same origin policy isn't an issue for your application, then you just need to fix the dataType
in your jQuery.ajax
call to be json
instead of jsonp
.
This will also change it into an array:
<?php
print_r((array) json_decode($object));
?>
Consider using the MySQL Installer for Windows as it installs and updates the various MySQL products on your system, including MySQL Server, MySQL Workbench, and MySQL Notifier. The Notifier monitors your MySQL instances so you'll know if MySQL is running, and it can also be used to start/stop MySQL.
It looks to me like PATH lists the first-generation dependencies directly from your gemspec, whereas GEM lists second-generation dependencies (i.e. what your dependencies depend on) and those from your Gemfile. PATH::remote is .
because it relied on a local gemspec in the current directory to find out what belongs in PATH::spec, whereas GEM::remote is rubygems.org
, since that's where it had to go to find out what belongs in GEM::spec.
In a Rails plugin, you'll see a PATH section, but not in a Rails app. Since the app doesn't have a gemspec file, there would be nothing to put in PATH.
As for DEPENDENCIES, gembundler.com states:
Runtime dependencies in your gemspec are treated like base dependencies,
and development dependencies are added by default to the group, :development
The Gemfile generated by rails plugin new my_plugin
says something similar:
# Bundler will treat runtime dependencies like base dependencies, and
# development dependencies will be added by default to the :development group.
What this means is that the difference between
s.add_development_dependency "july" # (1)
and
s.add_dependency "july" # (2)
is that (1) will only include "july" in Gemfile.lock (and therefore in the application) in a development environment. So when you run bundle install
, you'll see "july" not only under PATH but also under DEPENDENCIES, but only in development. In production, it won't be there at all. However, when you use (2), you'll see "july" only in PATH, not in DEPENDENCIES, but it will show up when you bundle install
from a production environment (i.e. in some other gem that includes yours as a dependency), not only development.
These are just my observations and I can't fully explain why any of this is the way it is but I welcome further comments.
Consider collections.Counter (available from python 2.7 onwards). https://docs.python.org/2/library/collections.html#collections.Counter
Also you can setup extJs writer
with encode
: true
and it will send data regularly (and, hence, you will be able to retrieve data via $_POST
and $_GET
).
... the values will be sent as part of the request parameters as opposed to a raw post (via docs for encode config of Ext.data.writer.Json)
UPDATE
Also docs say that:
The encode option should only be set to true when a root is defined
So, probably, writer
's root
config is required.
Note: MDN gives a method using a while loop:
var indices = [];
var array = ['a', 'b', 'a', 'c', 'a', 'd'];
var element = 'a';
var idx = array.indexOf(element);
while (idx != -1) {
indices.push(idx);
idx = array.indexOf(element, idx + 1);
}
I wouldn't say it's any better than other answers. Just interesting.
try:
var myjson = '{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}';
var newJ= $.parseJSON(myjson);
alert(newJ.TeamList[0].teamname);
UPDATE
only changes the values you specify:
UPDATE table SET cell='new_value' WHERE whatever='somevalue'
There is a crop()
method:
w, h = yourImage.size
yourImage.crop((0, 30, w, h-30)).save(...)
select * from yourtable
where created < now()
and created > concat(curdate(),' 4:30:00 AM')
$(document).on('change','#multiid',function(){

Of cause it's possible to create dynamic classes using very cool ExpandoObject class. But recently I worked on project and faced that Expando Object is serealized in not the same format on xml as an simple Anonymous class, it was pity =( , that is why I decided to create my own class and share it with you. It's using reflection and dynamic directive , builds Assembly, Class and Instance truly dynamicly. You can add, remove and change properties that is included in your class on fly Here it is :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Reflection.Emit;
using static YourNamespace.DynamicTypeBuilderTest;
namespace YourNamespace
{
/// This class builds Dynamic Anonymous Classes
public class DynamicTypeBuilderTest
{
///
/// Create instance based on any Source class as example based on PersonalData
///
public static object CreateAnonymousDynamicInstance(PersonalData personalData, Type dynamicType, List<ClassDescriptorKeyValue> classDescriptionList)
{
var obj = Activator.CreateInstance(dynamicType);
var propInfos = dynamicType.GetProperties();
classDescriptionList.ForEach(x => SetValueToProperty(obj, propInfos, personalData, x));
return obj;
}
private static void SetValueToProperty(object obj, PropertyInfo[] propInfos, PersonalData aisMessage, ClassDescriptorKeyValue description)
{
propInfos.SingleOrDefault(x => x.Name == description.Name)?.SetValue(obj, description.ValueGetter(aisMessage), null);
}
public static dynamic CreateAnonymousDynamicType(string entityName, List<ClassDescriptorKeyValue> classDescriptionList)
{
AssemblyName asmName = new AssemblyName();
asmName.Name = $"{entityName}Assembly";
AssemblyBuilder assemblyBuilder = AssemblyBuilder.DefineDynamicAssembly(asmName, AssemblyBuilderAccess.RunAndCollect);
ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule($"{asmName.Name}Module");
TypeBuilder typeBuilder = moduleBuilder.DefineType($"{entityName}Dynamic", TypeAttributes.Public);
classDescriptionList.ForEach(x => CreateDynamicProperty(typeBuilder, x));
return typeBuilder.CreateTypeInfo().AsType();
}
private static void CreateDynamicProperty(TypeBuilder typeBuilder, ClassDescriptorKeyValue description)
{
CreateDynamicProperty(typeBuilder, description.Name, description.Type);
}
///
///Creation Dynamic property (from MSDN) with some Magic
///
public static void CreateDynamicProperty(TypeBuilder typeBuilder, string name, Type propType)
{
FieldBuilder fieldBuider = typeBuilder.DefineField($"{name.ToLower()}Field",
propType,
FieldAttributes.Private);
PropertyBuilder propertyBuilder = typeBuilder.DefineProperty(name,
PropertyAttributes.HasDefault,
propType,
null);
MethodAttributes getSetAttr =
MethodAttributes.Public | MethodAttributes.SpecialName |
MethodAttributes.HideBySig;
MethodBuilder methodGetBuilder =
typeBuilder.DefineMethod($"get_{name}",
getSetAttr,
propType,
Type.EmptyTypes);
ILGenerator methodGetIL = methodGetBuilder.GetILGenerator();
methodGetIL.Emit(OpCodes.Ldarg_0);
methodGetIL.Emit(OpCodes.Ldfld, fieldBuider);
methodGetIL.Emit(OpCodes.Ret);
MethodBuilder methodSetBuilder =
typeBuilder.DefineMethod($"set_{name}",
getSetAttr,
null,
new Type[] { propType });
ILGenerator methodSetIL = methodSetBuilder.GetILGenerator();
methodSetIL.Emit(OpCodes.Ldarg_0);
methodSetIL.Emit(OpCodes.Ldarg_1);
methodSetIL.Emit(OpCodes.Stfld, fieldBuider);
methodSetIL.Emit(OpCodes.Ret);
propertyBuilder.SetGetMethod(methodGetBuilder);
propertyBuilder.SetSetMethod(methodSetBuilder);
}
public class ClassDescriptorKeyValue
{
public ClassDescriptorKeyValue(string name, Type type, Func<PersonalData, object> valueGetter)
{
Name = name;
ValueGetter = valueGetter;
Type = type;
}
public string Name;
public Type Type;
public Func<PersonalData, object> ValueGetter;
}
///
///Your Custom class description based on any source class for example
/// PersonalData
public static IEnumerable<ClassDescriptorKeyValue> GetAnonymousClassDescription(bool includeAddress, bool includeFacebook)
{
yield return new ClassDescriptorKeyValue("Id", typeof(string), x => x.Id);
yield return new ClassDescriptorKeyValue("Name", typeof(string), x => x.FirstName);
yield return new ClassDescriptorKeyValue("Surname", typeof(string), x => x.LastName);
yield return new ClassDescriptorKeyValue("Country", typeof(string), x => x.Country);
yield return new ClassDescriptorKeyValue("Age", typeof(int?), x => x.Age);
yield return new ClassDescriptorKeyValue("IsChild", typeof(bool), x => x.Age < 21);
if (includeAddress)
yield return new ClassDescriptorKeyValue("Address", typeof(string), x => x?.Contacts["Address"]);
if (includeFacebook)
yield return new ClassDescriptorKeyValue("Facebook", typeof(string), x => x?.Contacts["Facebook"]);
}
///
///Source Data Class for example
/// of cause you can use any other class
public class PersonalData
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Country { get; set; }
public int Age { get; set; }
public Dictionary<string, string> Contacts { get; set; }
}
}
}
It is also very simple to use DynamicTypeBuilder, you just need put few lines like this:
public class ExampleOfUse
{
private readonly bool includeAddress;
private readonly bool includeFacebook;
private readonly dynamic dynamicType;
private readonly List<ClassDescriptorKeyValue> classDiscriptionList;
public ExampleOfUse(bool includeAddress = false, bool includeFacebook = false)
{
this.includeAddress = includeAddress;
this.includeFacebook = includeFacebook;
this.classDiscriptionList = DynamicTypeBuilderTest.GetAnonymousClassDescription(includeAddress, includeFacebook).ToList();
this.dynamicType = DynamicTypeBuilderTest.CreateAnonymousDynamicType("VeryPrivateData", this.classDiscriptionList);
}
public object Map(PersonalData privateInfo)
{
object dynamicObject = DynamicTypeBuilderTest.CreateAnonymousDynamicInstance(privateInfo, this.dynamicType, classDiscriptionList);
return dynamicObject;
}
}
I hope that this code snippet help somebody =) Enjoy!
You could use something like this:
import re
s = #that big string
# the parenthesis create a group with what was matched
# and '\w' matches only alphanumeric charactes
p = re.compile("name +(\w+) +is valid", re.flags)
# use search(), so the match doesn't have to happen
# at the beginning of "big string"
m = p.search(s)
# search() returns a Match object with information about what was matched
if m:
name = m.group(1)
else:
raise Exception('name not found')
here is another solution:
$cleaner_input = strip_tags($text);

I have this issue too. I am running 1.6 but want to build the code I'm working on with 1.5. I've changed the JAVA_HOME
and PATH
(both user and system) to no avail.
The answer is that the installer for 1.6 dropped java.exe
, javaw.exe
, and javaws.exe
into my Windows\System32
folder (Windows 7).
I solved it by renaming those files to java_wrong.exe
, javaw_wrong.exe
, and javaws_wrong.exe
. Only after doing that does it pick up the correct version of java as defined in JAVA_HOME
and PATH
. I renamed the files thusly because that deleted them in an easily reversible manner.
Hope this helps!
Make sure you have a service started and listening on the port.
netstat -ln | grep 8080
and
sudo netstat -tulpn
Although I've used the accepted answer in the past, it seems with the current Build Tools it is possible to do:
<dimen name="listAvatarWidthPercent">0.19</dimen>
I'm using Build Tools major version 29.
Simple just run the following command to get the output to your terminal:
adb shell logcat
this make me success!
prefix: classpath:/templates/
check your application.yml
My personal preference is to use grep and the while command. This allows one to write powerful yet readable scripts ensuring that you end up doing exactly what you want. Plus by using an echo command you can perform a dry run before carrying out the actual operation. For example:
ls | grep -v "Music" | while read filename
do
echo $filename
done
will print out the files that you will end up copying. If the list is correct the next step is to simply replace the echo command with the copy command as follows:
ls | grep -v "Music" | while read filename
do
cp "$filename" /target_directory
done
Try this
function readRows() {
var sheet = SpreadsheetApp.getActiveSheet();
var rows = sheet.getDataRange();
var numRows = rows.getNumRows();
//var values = rows.getValues();
var Names = sheet.getRange("A2:A7");
var Name = [
Names.getCell(1, 1).getValue(),
Names.getCell(2, 1).getValue(),
.....
Names.getCell(5, 1).getValue()]
You can define arrays simply as follows, instead of allocating and then assigning.
var arr = [1,2,3,5]
Your initial error was because of the following line, and ones like it
var Name[0] = Name_cell.getValue();
Since Name
is already defined and you are assigning the values to its elements, you should skip the var
, so just
Name[0] = Name_cell.getValue();
Pro tip: For most issues that, like this one, don't directly involve Google services, you are better off Googling for the way to do it in javascript in general.
This worked for me: .\mongod --dbpath c:......
You can simply use MaterialAlertDialogBuilder to create custom dialog with rounded corners.
First create a style for the material dialog like this :
<style name="MyRounded.MaterialComponents.MaterialAlertDialog" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay.App.CustomDialog.Rounded
</item>
<item name="colorSurface">@color/YOUR_COLOR</item>
</style>
<style name="ShapeAppearanceOverlay.App.CustomDialog.Rounded" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">10dp</item>
</style>
then create a Alert Dialog object in Java class like this :
AlertDialog alertDialog = new MaterialAlertDialogBuilder(this,R.style.MyRounded_MaterialComponents_MaterialAlertDialog) // for fragment you can use getActivity() instead of this
.setView(R.layout.custom_layout) // custom layout is here
.show();
final EditText editText = alertDialog.findViewById(R.id.custom_layout_text); // access to text view of custom layout
Button btn = alertDialog.findViewById(R.id.custom_layout_btn);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d(TAG, "onClick: " + editText.getText().toString());
}
});
That's all you need to do.
what you could do, is put an if statement around everything inside the loop that you want kept away from the 50. e.g.
for i in range(0, len(list)):
if i != 50:
x= listRow(list, i)
for j in range (#0 to len(list) not including x#)
Often classes are used to enclose methods and following is the extension for answers above with default method in case the method is not found.
class P:
def p1(self):
print('Start')
def p2(self):
print('Help')
def ps(self):
print('Settings')
def d(self):
print('Default function')
myDict = {
"start": p1,
"help": p2,
"settings": ps
}
def call_it(self):
name = 'start'
f = lambda self, x : self.myDict.get(x, lambda x : self.d())(self)
f(self, name)
p = P()
p.call_it()
var fs = require('fs');
function base64Encode(file) {
var body = fs.readFileSync(file);
return body.toString('base64');
}
var base64String = base64Encode('test.jpg');
console.log(base64String);
You can break up long lines with the caret ^
as long as you remember that the caret and the newline following it are completely removed. So, if there should be a space where you're breaking the line, include a space. (More on that below.)
Example:
copy file1.txt file2.txt
would be written as:
copy file1.txt^
file2.txt
Below function to save files, just pass your base64 file, it return filename save it in DB.
import fs from 'fs';
const uuid = require('uuid/v1');
/*Download the base64 image in the server and returns the filename and path of image.*/
function saveImage(baseImage) {
/*path of the folder where your project is saved. (In my case i got it from config file, root path of project).*/
const uploadPath = "/home/documents/project";
//path of folder where you want to save the image.
const localPath = `${uploadPath}/uploads/images/`;
//Find extension of file
const ext = baseImage.substring(baseImage.indexOf("/")+1, baseImage.indexOf(";base64"));
const fileType = baseImage.substring("data:".length,baseImage.indexOf("/"));
//Forming regex to extract base64 data of file.
const regex = new RegExp(`^data:${fileType}\/${ext};base64,`, 'gi');
//Extract base64 data.
const base64Data = baseImage.replace(regex, "");
const filename = `${uuid()}.${ext}`;
//Check that if directory is present or not.
if(!fs.existsSync(`${uploadPath}/uploads/`)) {
fs.mkdirSync(`${uploadPath}/uploads/`);
}
if (!fs.existsSync(localPath)) {
fs.mkdirSync(localPath);
}
fs.writeFileSync(localPath+filename, base64Data, 'base64');
return filename;
}

You can use std::numeric_limits
which is defined in <limits>
to find the minimum or maximum value of types (As long as a specialization exists for the type). You can also use it to retrieve infinity (and put a -
in front for negative infinity).
#include <limits>
//...
std::numeric_limits<float>::max();
std::numeric_limits<float>::min();
std::numeric_limits<float>::infinity();
As noted in the comments, min()
returns the lowest possible positive value. In other words the positive value closest to 0 that can be represented. The lowest possible value is the negative of the maximum possible value.
There is of course the std::max_element
and min_element functions (defined in <algorithm>
) which may be a better choice for finding the largest or smallest value in an array.
In laravel you can use following syntax
@php
$description='<p>Rolling coverage</p><ul><li><a href="http://xys.com">Brexit deal: May admits she would have </a><br></li></ul></p>'
@endphp
{{ strip_tags($description)}}

You can create generic DialogFragment subclasses like YesNoDialog and OkDialog, and pass in title and message if you use dialogs a lot in your app.
public class YesNoDialog extends DialogFragment
{
public static final String ARG_TITLE = "YesNoDialog.Title";
public static final String ARG_MESSAGE = "YesNoDialog.Message";
public YesNoDialog()
{
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
Bundle args = getArguments();
String title = args.getString(ARG_TITLE);
String message = args.getString(ARG_MESSAGE);
return new AlertDialog.Builder(getActivity())
.setTitle(title)
.setMessage(message)
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
getTargetFragment().onActivityResult(getTargetRequestCode(), Activity.RESULT_OK, null);
}

.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
getTargetFragment().onActivityResult(getTargetRequestCode(), Activity.RESULT_CANCELED, null);

})
.create();
}
}
Then call it using the following:
DialogFragment dialog = new YesNoDialog();
Bundle args = new Bundle();
args.putString(YesNoDialog.ARG_TITLE, title);
args.putString(YesNoDialog.ARG_MESSAGE, message);
dialog.setArguments(args);
dialog.setTargetFragment(this, YES_NO_CALL);
dialog.show(getFragmentManager(), "tag");
And handle the result in onActivityResult
.
There are three good answers to this question.
unsrt
bibliography style, if you're happy with its formatting otherwisemakebst
(link) tool to design your own bibliography styleAnd my personal recommendation:
biblatex
package (link). It's the most complete and flexible bibliography tool in the LaTeX world.Using biblatex
, you'd write something like
\documentclass[12pt]{article}
\usepackage[sorting=none]{biblatex}
\bibliography{journals,phd-references} % Where journals.bib and phd-references.bib are BibTeX databases
\begin{document}
\cite{robertson2007}
\cite{earnshaw1842}
\printbibliography
\end{document}
I have solved it outside Angular. I have defined a shared scss that I'm importing to my children.
shared.scss
%cell {
color: #333333;
background: #eee;
font-size: 13px;
font-weight: 600;
}
child.scss
@import 'styles.scss';
.cell {
@extend %cell;
}
My proposed approach is a way how to solve the problem the OP has asked about. As mentioned at multiple occasions, ::ng-deep, :ng-host will get depreciated and disabling encapsulation is just too much of a code leakage, in my view.
You have an error in your OrderQuantity column. It is named "OrderQuantity" in the INSERT statement and "OrderQantity" in the table definition.
Also, I don't think you can use NOW()
as default value in OrderDate. Try to use the following:
OrderDate TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
There is a super() in python also.
Example for how a super class method is called from a sub class method
class Dog(object):
name = ''
moves = []
def __init__(self, name):
self.name = name
def moves_setup(self,x):
self.moves.append('walk')
self.moves.append('run')
self.moves.append(x)
def get_moves(self):
return self.moves
class Superdog(Dog):
#Let's try to append new fly ability to our Superdog
def moves_setup(self):
#Set default moves by calling method of parent class
super().moves_setup("hello world")
self.moves.append('fly')
dog = Superdog('Freddy')
print (dog.name)
dog.moves_setup()
print (dog.get_moves())
This example is similar to the one explained above.However there is one difference that super doesn't have any arguments passed to it.This above code is executable in python 3.4 version.
I was looking for "javascript prevent select change" on Google and this question comes at first result. At the end my solution was:
const $select = document.querySelector("#your_select_id");
let lastSelectedIndex = $select.selectedIndex;
// We save the last selected index on click
$select.addEventListener("click", function () {
lastSelectedIndex = $select.selectedIndex;
});
// And then, in the change, we select it if the user does not confirm
$select.addEventListener("change", function (e) {
if (!confirm("Some question or action")) {
$select.selectedIndex = lastSelectedIndex;
return;
}
// Here do whatever you want; the user has clicked "Yes" on the confirm
// ...
});
I hope it helps to someone who is looking for this and does not have jQuery :)
OP here, I have learned a lot more about node since I first asked this question. Though Dmitry's answer was very helpful, what ultimately did it for me is to install node with the correct permissions.
I highly recommend not installing node using any package managers, but rather to compile it yourself so that it resides in a local directory with normal permissions.
This article provides a very clear step-by-step instruction of how to do so:
When you are working with a Gitlab or Github you can run in trouble in this way. You squash your commits with one of the above method. My preferite one is:
git rebase -i HEAD~4
or
git rebase -i origin/master
select squash or fixup for yours commit. At this point you would check with git status. And the message could be:
On branch ABC-1916-remote
Your branch and 'origin/ABC-1916' have diverged,
and have 1 and 7 different commits each, respectively.
(use "git pull" to merge the remote branch into yours)
And you can be tempted to pull it. DO NOT DO THAT or you will be in the same situation as before.
Instead push to your origin with:
git push origin +ABC-1916-remote:ABC-1916
The + allow to force push only to one branch.
Just for completion the data.table solution:
library(data.table)
mydf <- structure(list(ID = c(110L, 111L, 121L, 131L, 141L),
MONTH.YEAR = c("JAN. 2012", "JAN. 2012",
"FEB. 2012", "FEB. 2012",
"MAR. 2012"),
VALUE = c(1000L, 2000L, 3000L, 4000L, 5000L)),
.Names = c("ID", "MONTH.YEAR", "VALUE"),
class = "data.frame", row.names = c(NA, -5L))
setDT(mydf)
mydf[, .(`Number of rows` = .N), by = MONTH.YEAR]
MONTH.YEAR Number of rows
1: JAN. 2012 2
2: FEB. 2012 2
3: MAR. 2012 1
Each method of mysqli can fail. You should test each return value. If one fails, think about whether it makes sense to continue with an object that is not in the state you expect it to be. (Potentially not in a "safe" state, but I think that's not an issue here.)
Since only the error message for the last operation is stored per connection/statement you might lose information about what caused the error if you continue after something went wrong. You might want to use that information to let the script decide whether to try again (only a temporary issue), change something or to bail out completely (and report a bug). And it makes debugging a lot easier.
$stmt = $mysqli->prepare("INSERT INTO testtable VALUES (?,?,?)");
// prepare() can fail because of syntax errors, missing privileges, ....
if ( false===$stmt ) {
// and since all the following operations need a valid/ready statement object
// it doesn't make sense to go on
// you might want to use a more sophisticated mechanism than die()
// but's it's only an example
die('prepare() failed: ' . htmlspecialchars($mysqli->error));
}
$rc = $stmt->bind_param('iii', $x, $y, $z);
// bind_param() can fail because the number of parameter doesn't match the placeholders in the statement
// or there's a type conflict(?), or ....
if ( false===$rc ) {
// again execute() is useless if you can't bind the parameters. Bail out somehow.
die('bind_param() failed: ' . htmlspecialchars($stmt->error));
}
$rc = $stmt->execute();
// execute() can fail for various reasons. And may it be as stupid as someone tripping over the network cable
// 2006 "server gone away" is always an option
if ( false===$rc ) {
die('execute() failed: ' . htmlspecialchars($stmt->error));
}
$stmt->close();
The mysqli extension is perfectly capable of reporting operations that result in an (mysqli) error code other than 0 via exceptions, see mysqli_driver::$report_mode.
die() is really, really crude and I wouldn't use it even for examples like this one anymore.
So please, only take away the fact that each and every (mysql) operation can fail for a number of reasons; even if the exact same thing went well a thousand times before....
One option is to have the page be blank, containing a small amount of javascript. Use the script to make an AJAX call to get the actual page content, and have the success function write the result over the current document. In the timeout function you can "do something else amazing"
Approximate pseudocode:
$(document).ready(function(){
$.ajax
url of actual page
success:do something amazing
timeout: do something else
});
There are two ways to split strings over multiple lines:
All lines in C can be split into multiple lines using \.
Plain C:
char *my_string = "Line 1 \
Line 2";
Objective-C:
NSString *my_string = @"Line1 \
Line2";
There's a better approach that works just for strings.
Plain C:
char *my_string = "Line 1 "
"Line 2";
Objective-C:
NSString *my_string = @"Line1 "
"Line2"; // the second @ is optional
The second approach is better, because there isn't a lot of whitespace included. For a SQL query however, both are possible.
NOTE: With a #define, you have to add an extra '\' to concatenate the two strings:
Plain C:
#define kMyString "Line 1"\
"Line 2"

For Express 4.0 I found that using application level variables works a little differently & Cory's answer did not work for me.
From the docs: http://expressjs.com/en/api.html#app.locals
I found that you could declare a global variable for the app in
app.locals
e.g
app.locals.baseUrl = "http://www.google.com"
And then in your application you can access these variables & in your express middleware you can access them in the req object as
req.app.locals.baseUrl
e.g.
console.log(req.app.locals.baseUrl)
//prints out http://www.google.com
Yes typically, a session will end after 20 minutes in PHP.
You have to compile with Java 1.7. But if you have *.jsp files, you should also completely remove Java 1.8 from the system. If you use Mac, here is how you can do it.
You can use JsonWriteNullProperties
for older versions of Jackson.
For Jackson 1.9+, use JsonSerialize.include
.
I also had the issue of broken service references when working with project references on both sides (the service project and the project having a reference to the service). If the the .dll of the referenced project for example is called "Contoso.Development.Common", but the projects name is simply shortened to "Common", also project references to this project are named just "Common". The service however expects a reference to "Contoso.Development.Common" for resolving classes (if this option is activated in the service reference options).
So with explorer I opened the folder of the project which is referencing the service and the "Common"-project. There I editet the VS project file (.csproj) with notepad. Search for the name of the refernced project (which is "Common.csproj" in this example) and you will quickly find the configuration entry representing the project reference.
I changed
<ProjectReference Include="..\Common\Common.csproj">
<Project>{C90AAD45-6857-4F83-BD1D-4772ED50D44C}</Project>
<Name>Common</Name>
</ProjectReference>
to
<ProjectReference Include="..\Common\Common.csproj">
<Project>{C90AAD45-6857-4F83-BD1D-4772ED50D44C}</Project>
<Name>Contoso.Development.Common</Name>
</ProjectReference>
The important thing is to change the name of the reference to the name of the dll the referenced project has as output.
Then switch back to VS. There you will be asked to reload the project since it has been modified outside of VS. Click the reload button.
After doing so adding und updating the service reference worked just as expected.
Hope this also helps someone else.

This hasn't solved my problem too, so I changed the parameters slightly.
This code worked for me:
var dataValue = "{ name: 'person', isGoing: 'true', returnAddress: 'returnEmail' }";
$.ajax({
type: "POST",
url: "Default.aspx/OnSubmit",
data: dataValue,
contentType: 'application/json; charset=utf-8',
dataType: 'json',
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
},
success: function (result) {
alert("We returned: " + result.d);
}
});
I found the SimpleLogger from heiswayi on GitHub good.
addressing the functional aspect:
function times(n, f) {
var _f = function (f) {
var i;
for (i = 0; i < n; i++) {
f(i);
}
};
return typeof f === 'function' && _f(f) || _f;
}
times(6)(function (v) {
console.log('in parts: ' + v);
});
times(6, function (v) {
console.log('complete: ' + v);
});
On windows use the name of the table in quotes:
TABLE "user";
or SELECT * FROM "user";
you can try to use cv2 like this
import cv2
image= cv2.imread('image page')
cv2.imshow('image', image)
cv2.waitKey(0)
cv2.destroyAllWindows()
You can use the provider-specific ConnectionStringBuilder class (within the appropriate namespace), or System.Data.Common.DbConnectionStringBuilder
to abstract the connection string object if you need to. You'd need to know the provider-specific keywords used to designate the information you're looking for, but for a SQL Server example you could do either of these two things:
System.Data.SqlClient.SqlConnectionStringBuilder builder = new System.Data.SqlClient.SqlConnectionStringBuilder(connectionString);
string server = builder.DataSource;
string database = builder.InitialCatalog;
or
System.Data.Common.DbConnectionStringBuilder builder = new System.Data.Common.DbConnectionStringBuilder();
builder.ConnectionString = connectionString;
string server = builder["Data Source"] as string;
string database = builder["Initial Catalog"] as string;
In Eclipse Ganymede (3.4.0):
One thing that i didn't see in other answers is To clarify another answers that there is a difference between returning std::unique_ptr that has been created within a function, and one that has been given to that function.
The example could be like this:
class Test
{int i;};
std::unique_ptr<Test> foo1()
{
std::unique_ptr<Test> res(new Test);
return res;
}
std::unique_ptr<Test> foo2(std::unique_ptr<Test>&& t)
{
// return t; // this will produce an error!
return std::move(t);
}
//...
auto test1=foo1();
auto test2=foo2(std::unique_ptr<Test>(new Test));
Installation of Maven doesn't create the settings.xml
file. You have to create it on your own. Just put it in your .m2
directory where you expected it, see http://maven.apache.org/settings.html for reference. The m2eclipse plugin will use the same settings file as the command line.
This function will tell you the x,y position of the element relative to the page. Basically you have to loop up through all the element's parents and add their offsets together.
function getPos(el) {
// yay readability
for (var lx=0, ly=0;
el != null;
lx += el.offsetLeft, ly += el.offsetTop, el = el.offsetParent);
return {x: lx,y: ly};
}
However, if you just wanted the x,y position of the element relative to its container, then all you need is:
var x = el.offsetLeft, y = el.offsetTop;
To put an element directly below this one, you'll also need to know its height. This is stored in the offsetHeight/offsetWidth property.
var yPositionOfNewElement = el.offsetTop + el.offsetHeight + someMargin;
Use Form
, not form
. The capitalization counts.
While I appreciate you believe absolute paths is not an option, it is a better option than relative paths and updating the PHP include path.
Use absolute paths with an constant you can set based on environment.
if (is_production()) {
define('ROOT_PATH', '/some/production/path');
}
else {
define('ROOT_PATH', '/root');
}
include ROOT_PATH . '/connect.php';
As commented, ROOT_PATH
could also be derived from the current path, $_SERVER['DOCUMENT_ROOT']
, etc.
This is possibly unrelated directly to the question; but one mistake I just made myself, and I see in the OP, is the URL specification ssh://user@server:/GitRepos/myproject.git
- namely, you have both a colon :
, and a forward slash /
after it signifying an absolute path.
I then found Git clone, ssh: Could not resolve hostname – git , development – Nicolas Kuttler (as that was the error I was getting, on git
version 1.7.9.5), noting:
The problem with the command I used initially was that I tried to use an scp-like syntax.
... which was also my problem! So basically in git
with ssh
, you either use
ssh://[email protected]/absolute/path/to/repo.git/
- just a forward slash for absolute path on server[email protected]:relative/path/to/repo.git/
- just a colon (it mustn't have the ssh://
for relative path on server (relative to home dir of username
on server machine)Hope this helps someone,
Cheers!

Inside a GitLab CI pipeline the CI_JOB_TOKEN
environment variable works for me:
git clone https://gitlab-ci-token:${CI_JOB_TOKEN}@gitlab.com/...
Source: Gitlab Docs
BTW, setting this variable in .gitlab-ci.yml
helps to debug errors.
variables:
CI_DEBUG_TRACE: "true"
list1 = [[], [], [], [], [], 'text', 'text2', [], 'moreText']
list2 = []
for item in list1:
if item!=[]:
list2.append(item)
print(list2)
output:
['text', 'text2', 'moreText']
It depends on what you need the result for.
If you are sure that there's going to be only 1 row, use implicit cursor:
DECLARE
v_foo foobar.foo%TYPE;
v_bar foobar.bar%TYPE;
BEGIN
SELECT foo,bar FROM foobar INTO v_foo, v_bar;
-- Print the foo and bar values
dbms_output.put_line('foo=' || v_foo || ', bar=' || v_bar);
EXCEPTION
WHEN NO_DATA_FOUND THEN
-- No rows selected, insert your exception handler here
WHEN TOO_MANY_ROWS THEN
-- More than 1 row seleced, insert your exception handler here
END;
If you want to select more than 1 row, you can use either an explicit cursor:
DECLARE
CURSOR cur_foobar IS
SELECT foo, bar FROM foobar;
v_foo foobar.foo%TYPE;
v_bar foobar.bar%TYPE;
BEGIN
-- Open the cursor and loop through the records
OPEN cur_foobar;
LOOP
FETCH cur_foobar INTO v_foo, v_bar;
EXIT WHEN cur_foobar%NOTFOUND;
-- Print the foo and bar values
dbms_output.put_line('foo=' || v_foo || ', bar=' || v_bar);
END LOOP;
CLOSE cur_foobar;
END;
or use another type of cursor:
BEGIN
-- Open the cursor and loop through the records
FOR v_rec IN (SELECT foo, bar FROM foobar) LOOP
-- Print the foo and bar values
dbms_output.put_line('foo=' || v_rec.foo || ', bar=' || v_rec.bar);
END LOOP;
END;
I'm posting a more declarative way of sync Base64 converting. While async fetch().blob()
is very neat and I like this solution a lot, it doesn't work on Internet Explorer 11 (and probably Edge - I haven't tested this one), even with the polyfill - take a look at my comment to Endless' post for more details.
const blobPdfFromBase64String = base64String => {
const byteArray = Uint8Array.from(
atob(base64String)
.split('')
.map(char => char.charCodeAt(0))
);
return new Blob([byteArray], { type: 'application/pdf' });
};
If you want to print it you could do something like:
const isIE11 = !!(window.navigator && window.navigator.msSaveOrOpenBlob); // Or however you want to check it
const printPDF = blob => {
try {
isIE11
? window.navigator.msSaveOrOpenBlob(blob, 'documents.pdf')
: printJS(URL.createObjectURL(blob)); // http://printjs.crabbly.com/
} catch (e) {
throw PDFError;
}
};
If you're able to do some preprocessing of the Base64 string on the server you could expose it under some URL and use the link in printJS
:)
You'll pick up c# fairly quickly (the language syntax is not that complicated). It will take you a long time to really learn the .NET framework, but you'll pick up the heavily used parts of the framework fairly quickly, and you should start seeing patterns in the framework.
My advice to you: don't just learn from a book or website. They will teach you the language and framework, but they will not teach you how to program anything useful.
Writing little code snippets will teach you how to do a very specific tasks, but they do not teach you how to write applications. My suggestion is that you think of an app that might be fun to work on (and doable... e.g. don't think that you're going to write an operating system or crysis or something in a month or two). Personally, when I was learning, wrote my own full featured IRC app, complete with rich text, personal messaging, etc.
Restartable mode (/Z) has to do with a partially-copied file. With this option, should the copy be interrupted while any particular file is partially copied, the next execution of robocopy can pick up where it left off rather than re-copying the entire file.
That option could be useful when copying very large files over a potentially unstable connection.
Backup mode (/B) has to do with how robocopy reads files from the source system. It allows the copying of files on which you might otherwise get an access denied error on either the file itself or while trying to copy the file's attributes/permissions. You do need to be running in an Administrator context or otherwise have backup rights to use this flag.
The calculation is simple
if you want to add 1 hour in the date .
every day have 24 hour , you can add .
select sysdate + 1/24 from dual;
if you want 1 day to add
select sysdate + 24/24 from dual;
or
select sysdate + 1 from dual;
same as for 2, 3 , 4 day
For static date you have the answer below.
You can begin by installing Node.js from terminal or cmd:
apt-get install nodejs-legacy npm
Then install the dependencies:
npm install
Then, start the server:
npm start
Backticks enclose template literals, previously known as template strings. Template literals are string literals that allow embedded expressions and string interpolation features.
Template literals have expressions embedded in placeholders, denoted by the dollar sign and curly brackets around an expression, i.e. ${expression}
. The placeholder / expressions get passed to a function. The default function just concatenates the string.
To escape a backtick, put a backslash before it:
`\`` === '`'; => true
Use backticks to more easily write multi-line string:
console.log(`string text line 1
string text line 2`);
or
console.log(`Fifteen is ${a + b} and
not ${2 * a + b}.`);
vs. vanilla JavaScript:
console.log('string text line 1\n' +
'string text line 2');
or
console.log('Fifteen is ' + (a + b) + ' and\nnot ' + (2 * a + b) + '.');
Escape sequences:
\u
, for example \u00A9
\u{}
, for example \u{2F804}
\x
, for example \xA9
\
and (a) digit(s), for example \251

This answer is a little long-winded, and the documentation will not tell you this (because they assume you are storing your dates as UTC dates in the database), but the answer to this question depends largely on the timezone that your dates are stored in. You also don't use Date('now')
, but use the julianday()
function, to calculate both dates back against a common date, then subtract the difference of those results from each other.
If your dates are stored in UTC:
SELECT julianday('now') - julianday(DateCreated) FROM Payment;
This is what the top-ranked answer has, and is also in the documentation. It is only part of the picture, and a very simplistic answer, if you ask me.
If your dates are stored in local time, using the above code will make your answer WRONG by the number of hours your GMT offset is. If you are in the Eastern U.S. like me, which is GMT -5, your result will have 5 hours added onto it. And if you try making DateCreated
conform to UTC because julianday('now')
goes against a GMT date:
SELECT julianday('now') - julianday(DateCreated, 'utc') FROM Payment;
This has a bug where it will add an hour for a DateCreated
that is during Daylight Savings Time (March-November). Say that "now" is at noon on a non-DST day, and you created something back in June (during DST) at noon, your result will give 1 hour apart, instead of 0 hours, for the hours portion. You'd have to write a function in your application's code that is displaying the result to modify the result and subtract an hour from DST dates. I did that, until I realized there's a better solution to that problem that I was having: SQLite vs. Oracle - Calculating date differences - hours
Instead, as was pointed out to me, for dates stored in local time, make both match to local time:
SELECT julianday('now', 'localtime') - julianday(DateCreated) FROM Payment;
Or append 'Z'
to local time:
julianday(datetime('now', 'localtime')||'Z') - julianday(CREATED_DATE||'Z')
Both of these seem to compensate and do not add the extra hour for DST dates and do straight subtraction - so that item created at noon on a DST day, when checking at noon on a non-DST day, will not get an extra hour when performing the calculation.
And while I recognize most will say don't store dates in local time in your database, and to store them in UTC so you don't run into this, well not every application has a world-wide audience, and not every programmer wants to go through the conversion of EVERY date in their system to UTC and back again every time they do a GET or SET in the database and deal with figuring out if something is local or in UTC.
So normally you would create a backing variable in the class and toggle it on click and tie a class binding to the variable. Something like:
@Component(
selector:'foo',
template:`<a (click)="onClick()"
[class.selected]="wasClicked">Link</a>
`)
export class MyComponent {
wasClicked = false;
onClick() {
this.wasClicked= !this.wasClicked;
}
}
lista = list.sort(lista)
This should be
lista.sort()
The .sort()
method is in-place, and returns None. If you want something not in-place, which returns a value, you could use
sorted_list = sorted(lista)
Aside #1: please don't call your lists list
. That clobbers the builtin list type.
Aside #2: I'm not sure what this line is meant to do:
print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")
is it simply
print "value 1a + value 2 = value 3a value 4"
? In other words, I don't know why you're calling str on things which are already str.
Aside #3: sometimes you use print("something")
(Python 3 syntax) and sometimes you use print "something"
(Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..
The exception TypeError: 'NoneType' object is not subscriptable
happens because the value of lista
is actually None
. You can reproduce TypeError
that you get in your code if you try this at the Python command line:
None[0]
The reason that lista
gets set to None is because the return value of list.sort()
is None
... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).
If you do not want to alter the original version you can use
other_list = sorted(lista)
I always use a timestamp as well to prevent browsers from caching the image. For example, if the user is rotating their avatar, it will often get cached and appear to not change.
var d = new Date();
var t = d.getTime();
$('#avatar').css("background-image", "url(" + iPath + "?" + t + ")");
public Form1()
{
InitializeComponent();
//this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
this.MaximizeBox = false;
this.MinimizeBox = false;
}
To get employee names starting with A or B listed in order...
select employee_name
from employees
where employee_name LIKE 'A%' OR employee_name LIKE 'B%'
order by employee_name
If you are using Microsoft SQL Server you could use
....
where employee_name LIKE '[A-B]%'
order by employee_name
This is not standard SQL though it just gets translated to the following which is.
WHERE employee_name >= 'A'
AND employee_name < 'C'
For all variants you would need to consider whether you want to include accented variants such as Á
and test whether the queries above do what you want with these on your RDBMS and collation options.
Solution for Jupyter notebook PIL image visualization with arbitrary number of images:
def show(*imgs, **kwargs):
'''Show in Jupyter notebook one or sequence of PIL images in a row. figsize - optional parameter, controlling size of the image.
Examples:
show(img)
show(img1,img2,img3)
show(img1,img2,figsize=[8,8])
'''
if 'figsize' not in kwargs:
figsize = [9,9]
else:
figsize = kwargs['figsize']
fig, ax = plt.subplots(1,len(imgs),figsize=figsize)
if len(imgs)==1:
ax=[ax]
for num,img in enumerate(imgs):
ax[num].imshow(img)
ax[num].axis('off')
tight_layout()
You can always do
git clone git://repo.org/fossproject.git && rm -rf fossproject/.git
Use dictionary comprehension way,
x = {k:v for k,v in enumerate(states) if v == True}
Input:
states = [False, False, False, False, True, True, False, True, False, False, False, False, False, False, False, False]
Output:
{4: True, 5: True, 7: True}
From at least, the 2.0
version, Spring-Data-Jpa
modified findOne()
.
Now, findOne()
has neither the same signature nor the same behavior.
Previously, it was defined in the CrudRepository
interface as:
T findOne(ID primaryKey);
Now, the single findOne()
method that you will find in CrudRepository
is the one defined in the QueryByExampleExecutor
interface as:
<S extends T> Optional<S> findOne(Example<S> example);
That is implemented finally by SimpleJpaRepository
, the default implementation of the CrudRepository
interface.
This method is a query by example search and you don't want that as a replacement.
In fact, the method with the same behavior is still there in the new API, but the method name has changed.
It was renamed from findOne()
to findById()
in the CrudRepository
interface :
Optional<T> findById(ID id);
Now it returns an Optional
, which is not so bad to prevent NullPointerException
.
So, the actual method to invoke is now Optional<T> findById(ID id)
.
How to use that?
Learning Optional
usage.
Here's important information about its specification:
A container object which may or may not contain a non-null value. If a value is present, isPresent() will return true and get() will return the value.
Additional methods that depend on the presence or absence of a contained value are provided, such as orElse() (return a default value if value not present) and ifPresent() (execute a block of code if the value is present).
Some hints on how to use Optional
with Optional<T> findById(ID id)
.
Generally, as you look for an entity by id, you want to return it or make a particular processing if that is not retrieved.
Here are three classical usage examples.
You could write :
Foo foo = repository.findById(id)
.orElse(new Foo());
or get a null
default value if it makes sense (same behavior as before the API change) :
Foo foo = repository.findById(id)
.orElse(null);
You could write :
return repository.findById(id)
.orElseThrow(() -> new EntityNotFoundException(id));
You could write :
Optional<Foo> fooOptional = fooRepository.findById(id);
if (fooOptional.isPresent()) {
Foo foo = fooOptional.get();
// processing with foo ...
} else {
// alternative processing....
}
Both .ics and .vcs files are in ASCII. If you use "Save As" option to save a calendar entry (Appt, Meeting Request/Response/Postpone/Cancel and etc) in both .ics and .vcs format and use vimdiff, you can easily see the difference.
Both .vcs (vCal) and .ics (iCal) belongs to the same VCALENDAR camp, but .vcs file shows "VERSION:1.0" whereas .ics file uses "VERSION:2.0".
The spec for vCalendar v1.0 can be found at http://www.imc.org/pdi/pdiproddev.html. The spec for iCalendar (vCalendar v2.0) is in RFC5545. In general, the newer is better, and that is true for Outlook 2007 and onward, but not for Outlook 2003.
For Outlook 2003, the behavior is peculiar. It can save the same calendar entry in both .ics and .vcs format, but it only read & display .vcs file correctly. It can read .ics file but it omits some fields and does not display it in calendar mode. My guess is that back then Microsoft wanted to provide .ics to be compatible with Mac's iCal but not quite committed to v2.0 yet.
So I would say for Outlook 2003, .vcs is the native format.
My suspect is of course actual base64 data, otherwise it looks good to me. See this fiddle where similar scheme is working. You may try specifying char set.
<div>_x000D_
<p>Taken from wikpedia</p>_x000D_
<img src="data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAUA_x000D_
AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO_x000D_
9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot" />_x000D_
</div>
_x000D_
You can try this base64 decoder to see if your base64 data is correct or not.
It seems i came late to the party, but you should better check this out too.
So in system.web
for caching up exceptions within the application such as return HttpNotFound()
<system.web>
<customErrors mode="RemoteOnly">
<error statusCode="404" redirect="/page-not-found" />
<error statusCode="500" redirect="/internal-server-error" />
</customErrors>
</system.web>
and in system.webServer
for catching up errors that were caught by IIS and did not made their way to the asp.net framework
<system.webServer>
<httpErrors errorMode="DetailedLocalOnly">
<remove statusCode="404"/>
<error statusCode="404" path="/page-not-found" responseMode="Redirect"/>
<remove statusCode="500"/>
<error statusCode="500" path="/internal-server-error" responseMode="Redirect"/>
</system.webServer>
In the last one if you worry about the client response then change the responseMode="Redirect"
to responseMode="File"
and serve a static html file, since this one will display a friendly page with an 200 response code.
you should be able to just overwrite it without removing previous data
What fixed this for me was that I had a React component being rendered prior to my core.js shim being loaded.
import ReactComponent from '.'
import 'core-js/es6'
Loading the core-js prior to the ReactComponent fixed my issue
import 'core-js/es6'
import ReactComponent from '.'
If you are looking to avoid the callbacks you can take advantage of the sdk .promise() function like this:
const s3 = new AWS.S3();
const params = {Bucket: 'myBucket', Key: 'myKey.csv'}
const response = await s3.getObject(params).promise() // await the promise
const fileContent = getObjectResult.Body.toString('utf-8'); // can also do 'base64' here if desired
I'm sure the other ways mentioned here have their advantages but this works great for me. Sourced from this thread (see the last response from AWS): https://forums.aws.amazon.com/thread.jspa?threadID=116788
Using alpha 28, I accomplished programmatically subscribing to event emitters by way of the eventEmitter.toRx().subscribe(..)
method. As it is not intuitive, it may perhaps change in a future release.
To access properties and methods of a parent class use the base
keyword. So in your child class LoadData()
method you would do this:
public class Child : Parent
{
public void LoadData()
{
base.MyMethod(); // call method of parent class
base.CurrentRow = 1; // set property of parent class
// other stuff...
}
}
Note that you would also have to change the access modifier of your parent MyMethod()
to at least protected
for the child class to access it.
You don't need jQuery for this. Here's a simple working example:
<!DOCTYPE html>
<html>
<head>
<title>box-shadow-experiment</title>
<style type="text/css">
#box-shadow-div{
position: fixed;
width: 1px;
height: 1px;
border-radius: 100%;
background-color:black;
box-shadow: 0 0 10px 10px black;
top: 49%;
left: 48.85%;
}
</style>
<script type="text/javascript">
window.onload = function(){
var bsDiv = document.getElementById("box-shadow-div");
var x, y;
// On mousemove use event.clientX and event.clientY to set the location of the div to the location of the cursor:
window.addEventListener('mousemove', function(event){
x = event.clientX;
y = event.clientY;
if ( typeof x !== 'undefined' ){
bsDiv.style.left = x + "px";
bsDiv.style.top = y + "px";
}
}, false);
}
</script>
</head>
<body>
<div id="box-shadow-div"></div>
</body>
</html>
I chose position: fixed;
so scrolling wouldn't be an issue.
This is super old, but I figured I'd add my 2c. DATE_FORMAT
does indeed return a string, but I was looking for the CAST
function, in the situation that I already had a datetime string in the database and needed to pattern match against it:
http://dev.mysql.com/doc/refman/5.0/en/cast-functions.html
In this case, you'd use:
CAST(date_value AS char)
This answers a slightly different question, but the question title seems ambiguous enough that this might help someone searching.
Here is a good starting point.
HTML:
<div class="containing-table">
<div class="centre-align">
<div class="content"></div>
</div>
</div>
CSS:
.containing-table {
display: table;
width: 100%;
height: 400px; /* for demo only */
border: 1px dotted blue;
}
.centre-align {
padding: 10px;
border: 1px dashed gray;
display: table-cell;
text-align: center;
vertical-align: middle;
}
.content {
width: 50px;
height: 50px;
background-color: red;
display: inline-block;
vertical-align: top; /* Removes the extra white space below the baseline */
}
See demo at: http://jsfiddle.net/audetwebdesign/jSVyY/
.containing-table
establishes the width and height context for .centre-align
(the table-cell).
You can apply text-align
and vertical-align
to alter .centre-align
as needed.
Note that .content
needs to use display: inline-block
if it is to be centered horizontally using the text-align property.
You need to wait for the emulator to full start - takes a few minutes. Once it is fully started (UI on the emulator will change), it should work.
You will need to restart the app after the emulator is running and choose the running emulator when prompted.
Better you copy and move them to your own resources. Some resources might not be available on previous Android versions. Here is a link with all drawables available on each Android version thanks to @fiXedd
You can use system.globalization to format a number in any required format.
For example:
system.globalization.cultureinfo ci = new system.globalization.cultureinfo("en-ca");
If you have a decimal d = 1.2300000
and you need to trim it to 2 decimal places then it can be printed like this d.Tostring("F2",ci);
where F2 is string formating to 2 decimal places and ci is the locale or cultureinfo.

I also had similar issue. Had correctly installed the application, had appropriately setup the JAVA_HOME, still it was not able to find the JDK and complains about the ver 1.6.0_17.
I no longer have any such version installed on my machine. After much digging I got onto the "HKEY_LOCAL_MACHINE\software\javasoft\Java Development Kit\
" where I found multiple JDK version being mentioned.
I removed all except 1.8.0_25 that I currently have on my machine. Restarted the Android Studio, and it worked without any problem. May be someone visit this page, facing similar issue, might help.
This should work for MVC3 & MVC4
@Html.TextBoxFor(m => m.Age, new { @Value = "12" })
If you want it to be a hidden field
@Html.TextBoxFor(m => m.Age, new { @Value = "12",@type="hidden" })
Open your logCat when trying to install the app. Set it to "No Filters". Search for "InstallAppProgress" package identifier. If the install fails you should see an "Installation error code". In my case it was
D/InstallAppProgress: Installation error code: -7
From here you can use this link to find information about your specific error code.
Try this:
@echo off
set run=
tasklist /fi "imagename eq notepad.exe" | find ":" > nul
if errorlevel 1 set run=yes
if "%run%"=="yes" echo notepad is running
if "%run%"=="" echo notepad is not running
pause
You should be able to do the count on the purch variable:
purch.Count();
e.g.
var purch = from purchase in myBlaContext.purchases
select purchase;
purch.Count();
This is an old thread but for more recent Jenkins versions (in my case Jenkins 2.135) that require a particular java JDK the following should help:
Note: This is for Centos 7 , other distros may have differing directory locations although I believe they are correct for ubuntu also.
Modify /etc/sysconfig/jenkins
and set variable JENKINS_JAVA_CMD="/<your desired jvm>/bin/java"
(root access require)
Example:
JENKINS_JAVA_CMD="/usr/lib/jvm/java-1.8.0-openjdk/bin/java"
Restart Jenkins (if jenkins is run as a service sudo service jenkins stop
then sudo service jenkins start
)
The above fixed my Jenkins install not starting after I upgraded to Java 10 and Jenkins to 2.135
The String pool (aka interning) and Integer pool blur the difference further, and may allow you to use ==
for objects in some cases instead of .equals
This can give you greater performance (?), at the cost of greater complexity.
E.g.:
assert "ab" == "a" + "b";
Integer i = 1;
Integer j = i;
assert i == j;
Complexity tradeoff: the following may surprise you:
assert new String("a") != new String("a");
Integer i = 128;
Integer j = 128;
assert i != j;
I advise you to stay away from such micro-optimization, and always use .equals
for objects, and ==
for primitives:
assert (new String("a")).equals(new String("a"));
Integer i = 128;
Integer j = 128;
assert i.equals(j);
In addition to previous answers there is one important for me note:
shelve
is JetBrains products feature (such as WebStorm
, PhpStorm
, PyCharm
, etc.). It puts shelved files into .idea/shelf
directory.
stash
is one of git
options. It puts stashed files under the .git
directory.
Use in the XML file.
Layout file
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:text="@string/stringtext"/>
or:
Use this inside the Java class
TextView textView =(TextView)findViewById(R.id.texviewid);
textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
worked for me too:
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date parsed = null;
try {
parsed = sdf.parse("02/01/2014");
} catch (ParseException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
java.sql.Date data = new java.sql.Date(parsed.getTime());
contato.setDataNascimento( data);
// Contato DataNascimento era Calendar
//contato.setDataNascimento(Calendar.getInstance());
// grave nessa conexão!!!
ContatoDao dao = new ContatoDao("mysql");
// método elegante
dao.adiciona(contato);
System.out.println("Banco: ["+dao.getNome()+"] Gravado! Data: "+contato.getDataNascimento());
Another helper to delay your code that is 100% Swift in usage and optionally allows for choosing a different thread to run your delayed code from:
public func delay(bySeconds seconds: Double, dispatchLevel: DispatchLevel = .main, closure: @escaping () -> Void) {
let dispatchTime = DispatchTime.now() + seconds
dispatchLevel.dispatchQueue.asyncAfter(deadline: dispatchTime, execute: closure)
}
public enum DispatchLevel {
case main, userInteractive, userInitiated, utility, background
var dispatchQueue: DispatchQueue {
switch self {
case .main: return DispatchQueue.main
case .userInteractive: return DispatchQueue.global(qos: .userInteractive)
case .userInitiated: return DispatchQueue.global(qos: .userInitiated)
case .utility: return DispatchQueue.global(qos: .utility)
case .background: return DispatchQueue.global(qos: .background)
}
}
}
Now you simply delay your code on the Main thread like this:
delay(bySeconds: 1.5) {
// delayed code
}
If you want to delay your code to a different thread:
delay(bySeconds: 1.5, dispatchLevel: .background) {
// delayed code that will run on background thread
}
If you prefer a Framework that also has some more handy features then checkout HandySwift. You can add it to your project via Carthage then use it exactly like in the examples above, e.g.:
import HandySwift
delay(bySeconds: 1.5) {
// delayed code
}
As Jage's answer removes the element completely, including event handlers and data, I'm adding a simple solution that doesn't do that, thanks to the detach
function.
var element = $('#childNode').detach();
$('#parentNode').append(element);
Edit:
Igor Mukhin suggested an even shorter version in the comments below:
$("#childNode").detach().appendTo("#parentNode");
You are missing the ?
in the second URL (Also, it should be URL-encoded to be %3F
).
Also, I believe that the remaining &
need to be URL, not HTML-encoded. Change &second=12&third=5
to %26second=12%26third=5
and everything should just work.
This:
&u=http://www.foobar.com/first=12&sec=25&position=2
should be:
&u=http://www.foobar.com/%3Ffirst=12%26sec=25%26position=2
I just came across the same issue, and solved it, but not before I found this post. And seeing as your question wasn't really answered, here's my solution (which will hopefully work for you, or anyone else searching for the same thing I did;
Instead of;
... AND WPP.COMMENT NOT LIKE '%CORE%' ...
Try;
... AND NOT WPP.COMMENT LIKE '%CORE%' ...
Basically moving the "NOT" the other side of the field I was evaluating worked for me.
As Muhammad said, there are situations in which you only sometimes wish to set a default value. A great example of this is a data structure which is first populated, then queried.
Consider a trie. When adding a word, if a subnode is needed but not present, it must be created to extend the trie. When querying for the presence of a word, a missing subnode indicates that the word is not present and it should not be created.
A defaultdict cannot do this. Instead, a regular dict with the get and setdefault methods must be used.
The easiest way to do this is :
ALTER TABLE db.TABLENAME ADD COLUMN [datatype] NOT NULL DEFAULT 'value'
Ex : Adding a column x (bit datatype) to a table ABC with default value 0
ALTER TABLE db.ABC ADD COLUMN x bit NOT NULL DEFAULT 0
PS : I am not a big fan of using the table designer for this. Its so much easier being conventional / old fashioned sometimes. :). Hope this helps answer
I use following function to convert normal date-time value to mysql datetime format.
private function ampmtosql($ampmdate) {
if($ampmdate == '')
return '';
$ampm = substr(trim(($ampmdate)), -2);
$datetimesql = substr(trim(($ampmdate)), 0, -3);
if ($ampm == 'pm') {
$hours = substr(trim($datetimesql), -5, 2);
if($hours != '12')
$datetimesql = date('Y-m-d H:i',strtotime('+12 hour',strtotime($datetimesql)));
}
elseif ($ampm == 'am') {
$hours = substr(trim($datetimesql), -5, 2);
if($hours == '12')
$datetimesql = date('Y-m-d H:i',strtotime('-12 hour',strtotime($datetimesql)));
}
return $datetimesql;
}
It converts datetime values like,
2015-06-04 09:55 AM -> 2015-06-04 09:55
2015-06-04 03:55 PM -> 2015-06-04 15:55
2015-06-04 12:30 AM -> 2015-06-04 00:55
Hope this will help someone.
Or you can use the fetch API
fetch(URL.createObjectURL(myBlob)).then(res => res.arrayBuffer())
I don't know what the performance difference is, and this will show up on your network tab in DevTools as well.
You are missing #
hash character before id selectors, this should work:
$(document).ready(function() {
$("#div2").hide();
$("#preview").click(function() {
$("#div1").hide();
$("#div2").show();
});
});
Files being different only by a numerical string can be sorted on this number at the condition that it is preceded by a separator.
In this case, the following syntax can be used:
ls -x1 file | sort -t'<char>' -n -k2
Example:
ls -1 TRA*log | sort -t'_' -n -k2
TRACE_1.log
TRACE_2.log
TRACE_3.log
TRACE_4.log
TRACE_5.log
TRACE_6.log
TRACE_7.log
TRACE_8.log
TRACE_9.log
TRACE_10.log
Before answering, let's add some background, explaining what this HEAD
is.
First of all what is HEAD?
HEAD
is simply a reference to the current commit (latest) on the current branch.
There can only be a single HEAD
at any given time (excluding git worktree
).
The content of HEAD
is stored inside .git/HEAD
and it contains the 40 bytes SHA-1 of the current commit.
detached HEAD
If you are not on the latest commit - meaning that HEAD
is pointing to a prior commit in history it's called detached HEAD
.
On the command line, it will look like this - SHA-1 instead of the branch name since the HEAD
is not pointing to the tip of the current branch:
git checkout
git checkout <commit_id>
git checkout -b <new branch> <commit_id>
git checkout HEAD~X // x is the number of commits to go back
This will checkout new branch pointing to the desired commit.
This command will checkout to a given commit.
At this point, you can create a branch and start to work from this point on.
# Checkout a given commit.
# Doing so will result in a `detached HEAD` which mean that the `HEAD`
# is not pointing to the latest so you will need to checkout branch
# in order to be able to update the code.
git checkout <commit-id>
# Create a new branch forked to the given commit
git checkout -b <branch name>
git reflog
You can always use the reflog
as well.
git reflog
will display any change which updated the HEAD
and checking out the desired reflog entry will set the HEAD
back to this commit.
Every time the HEAD is modified there will be a new entry in the reflog
git reflog
git checkout HEAD@{...}
This will get you back to your desired commit
git reset --hard <commit_id>
"Move" your HEAD back to the desired commit.
# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32
# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts if you've modified things which were
# changed since the commit you reset to.
git rebase --no-autostash
as well.git revert <sha-1>
"Undo" the given commit or commit range.
The reset command will "undo" any changes made in the given commit.
A new commit with the undo patch will be committed while the original commit will remain in the history as well.
# Add a new commit with the undo of the original one.
# The <sha-1> can be any commit(s) or commit range
git revert <sha-1>
This schema illustrates which command does what.
As you can see there, reset && checkout
modify the HEAD
.
Java script plays on browser where java code is server side thing so you can't simply do this.
What you can do is submit the calculated variable from javascript to server by form-submission, or using URL parameter or using AJAX calls and then you can make it available on server
HTML
<input type="hidden" id="hiddenField"/>
make sure this fields lays under <form>
Javascript
document.getElementById("hiddenField").value=yourCalculatedVariable;
on server you would get this as a part of request
Java is a byte-compiled language targeting a platform called the Java Virtual Machine which is stack-based and has some very fast implementations on many platforms.
Something like this could work
input(type='file', name='videoFile', value = "Choose a video please")
Add a DoEvents function inside the loop, see below.
You may also want to ensure that the Status bar is visible to the user and reset it when your code completes.
Sub ProgressMeter()
Dim booStatusBarState As Boolean
Dim iMax As Integer
Dim i As Integer
iMax = 10000
Application.ScreenUpdating = False
''//Turn off screen updating
booStatusBarState = Application.DisplayStatusBar
''//Get the statusbar display setting
Application.DisplayStatusBar = True
''//Make sure that the statusbar is visible
For i = 1 To iMax ''// imax is usually 30 or so
fractionDone = CDbl(i) / CDbl(iMax)
Application.StatusBar = Format(fractionDone, "0%") & " done..."
''// or, alternatively:
''// statusRange.value = Format(fractionDone, "0%") & " done..."
''// Some code.......
DoEvents
''//Yield Control
Next i
Application.DisplayStatusBar = booStatusBarState
''//Reset Status bar display setting
Application.StatusBar = False
''//Return control of the Status bar to Excel
Application.ScreenUpdating = True
''//Turn on screen updating
End Sub
Assume n=2. Then we have 2-1 = 1 on the left side and 2*1/2 = 1 on the right side.
Denote f(n) = (n-1)+(n-2)+(n-3)+...+1
Now assume we have tested up to n=k. Then we have to test for n=k+1.
on the left side we have k+(k-1)+(k-2)+...+1, so it's f(k)+k
On the right side we then have (k+1)*k/2 = (k^2+k)/2 = (k^2 +2k - k)/2 = k+(k-1)k/2 = kf(k)
So this have to hold for every k, and this concludes the proof.
If you want to enable general error logs and slow query error log in the table instead of file
To start logging in table instead of file:
set global log_output = “TABLE”;
To enable general and slow query log:
set global general_log = 1;
set global slow_query_log = 1;
To view the logs:
select * from mysql.slow_log;
select * from mysql.general_log;

Do NOT do this:
git branch -t newbranch
git reset --hard HEAD~3
git checkout newbranch
As the next time you run git rebase
(or git pull --rebase
) those 3 commits would be silently discarded from newbranch
! (see explanation below)
Instead do this:
git reset --keep HEAD~3
git checkout -t -b newbranch
git cherry-pick ..HEAD@{2}
--keep
is like --hard
, but safer, as fails rather than throw away uncommitted changes).newbranch
.newbranch
. Since they're no longer referenced by a branch, it does that by using git's reflog: HEAD@{2}
is the commit that HEAD
used to refer to 2 operations ago, i.e. before we 1. checked out newbranch
and 2. used git reset
to discard the 3 commits.Warning: the reflog is enabled by default, but if you've manually disabled it (e.g. by using a "bare" git repository), you won't be able to get the 3 commits back after running git reset --keep HEAD~3
.
An alternative that doesn't rely on the reflog is:
# newbranch will omit the 3 most recent commits.
git checkout -b newbranch HEAD~3
git branch --set-upstream-to=oldbranch
# Cherry-picks the extra commits from oldbranch.
git cherry-pick ..oldbranch
# Discards the 3 most recent commits from oldbranch.
git branch --force oldbranch oldbranch~3
(if you prefer you can write @{-1}
- the previously checked out branch - instead of oldbranch
).
Why would git rebase
discard the 3 commits after the first example? It's because git rebase
with no arguments enables the --fork-point
option by default, which uses the local reflog to try to be robust against the upstream branch being force-pushed.
Suppose you branched off origin/master when it contained commits M1, M2, M3, then made three commits yourself:
M1--M2--M3 <-- origin/master
\
T1--T2--T3 <-- topic
but then someone rewrites history by force-pushing origin/master to remove M2:
M1--M3' <-- origin/master
\
M2--M3--T1--T2--T3 <-- topic
Using your local reflog, git rebase
can see that you forked from an earlier incarnation of the origin/master branch, and hence that the M2 and M3 commits are not really part of your topic branch. Hence it reasonably assumes that since M2 was removed from the upstream branch, you no longer want it in your topic branch either once the topic branch is rebased:
M1--M3' <-- origin/master
\
T1'--T2'--T3' <-- topic (rebased)
This behavior makes sense, and is generally the right thing to do when rebasing.
So the reason that the following commands fail:
git branch -t newbranch
git reset --hard HEAD~3
git checkout newbranch
is because they leave the reflog in the wrong state. Git sees newbranch
as having forked off the upstream branch at a revision that includes the 3 commits, then the reset --hard
rewrites the upstream's history to remove the commits, and so next time you run git rebase
it discards them like any other commit that has been removed from the upstream.
But in this particular case we want those 3 commits to be considered as part of the topic branch. To achieve that, we need to fork off the upstream at the earlier revision that doesn't include the 3 commits. That's what my suggested solutions do, hence they both leave the reflog in the correct state.
For more details, see the definition of --fork-point
in the git rebase and git merge-base docs.
I have problems as well with setting custom http authentication because $resource cache the request.
To make it work you have to overwrite the existing headers by doing this
var transformRequest = function(data, headersGetter){
var headers = headersGetter();
headers['Authorization'] = 'WSSE profile="UsernameToken"';
headers['X-WSSE'] = 'UsernameToken ' + nonce
headers['Content-Type'] = 'application/json';
};
return $resource(
url,
{
},
{
query: {
method: 'POST',
url: apiURL + '/profile',
transformRequest: transformRequest,
params: {userId: '@userId'}
},
}
);
I hope I was able to help someone. It took me 3 days to figure this one out.
See Apple’s Info.plist reference for full details (thanks @gnasher729).
You can add exceptions for specific domains in your Info.plist:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>testdomain.com</key>
<dict>
<key>NSIncludesSubdomains</key>
<true/>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSExceptionRequiresForwardSecrecy</key>
<true/>
<key>NSExceptionMinimumTLSVersion</key>
<string>TLSv1.2</string>
<key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key>
<false/>
<key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
<true/>
<key>NSThirdPartyExceptionMinimumTLSVersion</key>
<string>TLSv1.2</string>
<key>NSRequiresCertificateTransparency</key>
<false/>
</dict>
</dict>
</dict>
All the keys for each excepted domain are optional. The speaker did not elaborate on any of the keys, but I think they’re all reasonably obvious.
(Source: WWDC 2015 session 703, “Privacy and Your App”, 30:18)
You can also ignore all app transport security restrictions with a single key, if your app has a good reason to do so:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
If your app does not have a good reason, you may risk rejection:
Setting NSAllowsArbitraryLoads to true will allow it to work, but Apple was very clear in that they intend to reject apps who use this flag without a specific reason. The main reason to use NSAllowsArbitraryLoads I can think of would be user created content (link sharing, custom web browser, etc). And in this case, Apple still expects you to include exceptions that enforce the ATS for the URLs you are in control of.
If you do need access to specific URLs that are not served over TLS 1.2, you need to write specific exceptions for those domains, not use NSAllowsArbitraryLoads set to yes. You can find more info in the NSURLSesssion WWDC session.
Please be careful in sharing the NSAllowsArbitraryLoads solution. It is not the recommended fix from Apple.
