It looks like you're having a permissions error, based on this message in your output: error: could not create '/lib/python2.7/site-packages/lxml': Permission denied
.
One thing you can try is doing a user install of the package with pip install lxml --user
. For more information on how that works, check out this StackOverflow answer. (Thanks to Ishaan Taylor for the suggestion)
You can also run pip install
as a superuser with sudo pip install lxml
but it is not generally a good idea because it can cause issues with your system-level packages.
Use Maven and use the maven-compiler-plugin to explicitly call the actual correct version JDK javac.exe command, because Maven could be running any version; this also catches the really stupid long standing bug in javac that does not spot runtime breaking class version jars and missing classes/methods/properties when compiling for earlier java versions! This later part could have easily been fixed in Java 1.5+ by adding versioning attributes to new classes, methods, and properties, or separate compiler versioning data, so is a quite stupid oversight by Sun and Oracle.
Place the var lfckv
inside the function. When that line is executed, the body isn't parsed yet and the element "lifecheck"
doesn't exist. This works perfectly fine:
function exefunction() {_x000D_
var lfckv = document.getElementById("lifecheck").checked;_x000D_
alert(lfckv);_x000D_
}
_x000D_
<label><input id="lifecheck" type="checkbox" >Lives</label>_x000D_
<button onclick="exefunction()">Check value</button>
_x000D_
For those who have the following error:
Error Code: 1290. The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
You can simply run this command to see which folder can load files from:
SHOW VARIABLES LIKE "secure_file_priv";
After that, you have to copy the files in that folder and run the query with LOAD DATA LOCAL INFILE
instead of LOAD DATA INFILE
.
The first answer is too complex, historic, and uninformative for my tastes.
It's actually rather simple. Docker provides for a functionality called multi-stage builds the basic idea here is to,
Let's start with the first. Very often with something like Debian you'll see.
RUN apt-get update \
&& apt-get dist-upgrade \
&& apt-get install <whatever> \
&& apt-get clean
We can explain all of this in terms of the above. The above command is chained together so it represents a single change with no intermediate Images required. If it was written like this,
RUN apt-get update ;
RUN apt-get dist-upgrade;
RUN apt-get install <whatever>;
RUN apt-get clean;
It would result in 3 more temporary intermediate Images. Having it reduced to one image, there is one remaining problem: apt-get clean
doesn't clean up artifacts used in the install. If a Debian maintainer includes in his install a script that modifies the system that modification will also be present in the final solution (see something like pepperflashplugin-nonfree
for an example of that).
By using a multi-stage build you get all the benefits of a single changed action, but it will require you to manually whitelist and copy over files that were introduced in the temporary image using the COPY --from
syntax documented here. Moreover, it's a great solution where there is no alternative (like an apt-get clean
), and you would otherwise have lots of un-needed files in your final image.

Well you could get the ip address using asp.net, then do a reverse DNS lookup on the ip to get the hostname.

First of all, please make sure your Database server is up and running. I was getting the same error, after trying all the answers listed here I found out that my Database server was not running.
You can check the same from MySQL Workbench, or Command line using
mysql -u USERNAME -p
This sounds obvious, but many times we assume that Database server is up and running all the time, especially when we are working on our local machine, when we restart/shutdown the machine, Database server will be shutdown automatically.
When you try to execute a program in unix (one with the executable bit set), the operating system will look at the first few bytes of the file. These form the so-called "magic number", which can be used to decide the format of the program and how to execute it.
#!
corresponds to the magic number 0x2321 (look it up in an ascii table). When the system sees that the magic number, it knows that it is dealing with a text script and reads until the next \n
(there is a limit, but it escapes me atm). Having identified the interpreter (the first argument after the shebang) it will call the interpreter.
Other files also have magic numbers. Try looking at a bitmap (.BMP) file via less
and you will see the first two characters are BM
. This magic number denotes that the file is indeed a bitmap.
Plain typo. hostspath
vs hostpath
;)
@echo off
set `hostspath`=%windir%\System32\drivers\etc\hosts
echo 62.116.159.4 ns1.intranet.de >> `%hostspath%`
echo 217.160.113.37 ns2.intranet.de >> `%hostpath%`
echo 89.146.248.4 ns3.intranet.de >> `%hostpath%`
echo 74.208.254.4 ns4.intranet.de >> `%hostpath%`
exit
Yes, it is because you are using auto layout. Setting the view frame and resizing mask will not work.
You should read Working with Auto Layout Programmatically and Visual Format Language.
You will need to get the current constraints, add the text field, adjust the contraints for the text field, then add the correct constraints on the text field.
Below code works for me
public static void sftpsript(String filepath) {
try {
String user ="demouser"; // username for remote host
String password ="demo123"; // password of the remote host
String host = "demo.net"; // remote host address
JSch jsch = new JSch();
Session session = jsch.getSession(user, host);
session.setPassword(password);
session.connect();
ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
sftpChannel.connect();
sftpChannel.put("I:/demo/myOutFile.txt", "/tmp/QA_Auto/myOutFile.zip");
sftpChannel.disconnect();
session.disconnect();
}catch(Exception ex){
ex.printStackTrace();
}
}
OR using StrictHostKeyChecking as "NO" (security consequences)
public static void sftpsript(String filepath) {
try {
String user ="demouser"; // username for remote host
String password ="demo123"; // password of the remote host
String host = "demo.net"; // remote host address
JSch jsch = new JSch();
Session session = jsch.getSession(user, host, 22);
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);;
session.setPassword(password);
System.out.println("user=="+user+"\n host=="+host);
session.connect();
ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
sftpChannel.connect();
sftpChannel.put("I:/demo/myOutFile.txt", "/tmp/QA_Auto/myOutFile.zip");
sftpChannel.disconnect();
session.disconnect();
}catch(Exception ex){
ex.printStackTrace();
}
}
What you mean to do is:
jQuery(this).prev("li").attr("id", "newID");
That will set the ID to the new ID
You need to use the as.Date formats correctly.
Eg.
x = '2012/07/25'
xd = as.Date(x,'%Y/%m/%d')
xd # Prints "2012-07-25"
R date formats are similary to *nix ones.
Doing a typeof(xd) shows it as a double ie. days since 1970.
You should look into Video For Everyone:
Video for Everybody is very simply a chunk of HTML code that embeds a video into a website using the HTML5 element which offers native playback in Firefox 3.5 and Safari 3 & 4 and an increasing number of other browsers.
The video is played by the browser itself. It loads quickly and doesn’t threaten to crash your browser.
In other browsers that do not support , it falls back to QuickTime.
If QuickTime is not installed, Adobe Flash is used. You can host locally or embed any Flash file, such as a YouTube video.
The only downside, is that you have to have 2/3 versions of the same video stored, but you can serve to every existing device/browser that supports video (i.e.: the iPhone).

Furthermore, if in the same Jenkins project we need to checkout several private GitHub repositories into several separate dirs under a project root. How can we do it please?
The Jenkin's Multiple SCMs Plugin has solved the several repositories problem for me very nicely. I have just got working a project build that checks out four different git repos under a common folder. (I'm a bit reluctant to use git super-projects as suggested previously by Lukasz Rzanek, as git is complex enough without submodules.)
For .ini files there is the ConfigParser module that provides a format compatible with .ini files.
Anyway there's nothing available for parsing complete .properties files, when I have to do that I simply use jython (I'm talking about scripting).
Are you sure the Start
method returns before the child process starts? I was always under the impression that Start
starts the child process synchronously.
If you want to wait until your child process finishes some sort of initialization then you need inter-process communication - see Interprocess communication for Windows in C# (.NET 2.0).
The problem is that if you include fun.cpp in two places in your program, you will end up defining it twice, which isn't valid.
You don't want to include cpp
files. You want to include header files.
The header file should just have the class definition. The corresponding cpp
file, which you will compile separately, will have the function definition.
fun.hpp:
#include <iostream>
class classA {
friend void funct();
public:
classA(int a=1,int b=2):propa(a),propb(b){std::cout<<"constructor\n";}
private:
int propa;
int propb;
void outfun(){
std::cout<<"propa="<<propa<<endl<<"propb="<<propb<< std::endl;
}
};
fun.cpp:
#include "fun.hpp"
using namespace std;
void funct(){
cout<<"enter funct"<<endl;
classA tmp(1,2);
tmp.outfun();
cout<<"exit funct"<<endl;
}
mainfile.cpp:
#include <iostream>
#include "fun.hpp"
using namespace std;
int main(int nargin,char* varargin[]) {
cout<<"call funct"<<endl;
funct();
cout<<"exit main"<<endl;
return 0;
}
Note that it is generally recommended to avoid using namespace std
in header files.
Here's how to force the target inside a click handler:
$('a#link_id').click(function() {
$(this).attr('target', '_blank');
});
Please just write a static method somewhere and write:
if( isSizeBetween(orderBean.getFiles(), 0, 5) ){
// do your stuff
}
You can also do this without using groupby or loc. By simply including the condition in code. Let the name of dataframe be df. Then you can try :
df[df['a']==1]['b'].sum()
or you can also try :
sum(df[df['a']==1]['b'])
Another way could be to use the numpy library of python :
import numpy as np
print(np.where(df['a']==1, df['b'],0).sum())
Take a look at this solution. As I know, Flashphoner allows to play Live audio+video stream in the pure HTML5 page.
They use MPEG1 and G.711 codecs for playback. The hack is rendering decoded video to HTML5 canvas element and playing decoded audio via HTML5 audio context.
Hope you realise, java.util.Enumeration
is different from the Java 1.5 Enum types.
You can simply use YourEnum.valueOf("String")
to get the equivalent enum type.
Thus if your enum is defined as so:
public enum Day {
SUNDAY, MONDAY, TUESDAY, WEDNESDAY,
THURSDAY, FRIDAY, SATURDAY
}
You could do this:
String day = "SUNDAY";
Day dayEnum = Day.valueOf(day);
The accepted answer seems not adequate in several situations.
To check whether the localStorage
or sessionStorage
are supported, I use the following snippet from MDN.
function storageAvailable(type) {
var storage;
try {
storage = window[type];
var x = '__storage_test__';
storage.setItem(x, x);
storage.removeItem(x);
return true;
}
catch(e) {
return e instanceof DOMException && (
// everything except Firefox
e.code === 22 ||
// Firefox
e.code === 1014 ||
// test name field too, because code might not be present
// everything except Firefox
e.name === 'QuotaExceededError' ||
// Firefox
e.name === 'NS_ERROR_DOM_QUOTA_REACHED') &&
// acknowledge QuotaExceededError only if there's something already stored
(storage && storage.length !== 0);
}
}
Use this snippet like this, and fallback to, for example, using cookie:
if (storageAvailable('localStorage')) {
// Yippee! We can use localStorage awesomeness
}
else {
// Too bad, no localStorage for us
document.cookie = key + "=" + encodeURIComponent(value) + expires + "; path=/";
}
I have made the fallbackstorage package which uses this snippet to check for the storage availability and fallback to a manually implemented MemoryStorage.
import {getSafeStorage} from 'fallbackstorage'
getSafeStorage().setItem('test', '1') // always work
You cannot decrypt this password again but there is another method named "pwdcompare". Here is a example how to use it with SQL syntax:
USE TEMPDB
GO
declare @hash varbinary (255)
CREATE TABLE tempdb..h (id_num int, hash varbinary (255))
SET @hash = pwdencrypt('123') -- encryption
INSERT INTO tempdb..h (id_num,hash) VALUES (1,@hash)
SET @hash = pwdencrypt('123')
INSERT INTO tempdb..h (id_num,hash) VALUES (2,@hash)
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 2
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
INSERT INTO tempdb..h (id_num,hash)
VALUES (3,CONVERT(varbinary (255),
0x01002D60BA07FE612C8DE537DF3BFCFA49CD9968324481C1A8A8FE612C8DE537DF3BFCFA49CD9968324481C1A8A8))
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 3
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
DROP TABLE tempdb..h
GO
I may be simplifying the issue, but does td {border-right: 1px solid red;} work for your table setup?
This is entirely implementation specific, but it appears that in the C++ environment you're working in, RAND_MAX
is equal to INT_MAX
.
Because of this, RAND_MAX + 1
exhibits undefined (overflow) behavior, and becomes INT_MIN
. While your initial statement was dividing (random # between 0 and INT_MAX
)/(INT_MAX
) and generating a value 0 <= r < 1
, now it's dividing (random # between 0 and INT_MAX
)/(INT_MIN
), generating a value -1 < r <= 0
In order to generate a random number 1 <= r < 2
, you would want
r = ((double) rand() / (RAND_MAX)) + 1
You can make method which return the datatable of given sql query:
public DataTable GetDataTable()
{
SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["BarManConnectionString"].ConnectionString);
conn.Open();
string query = "SELECT * FROM [EventOne] ";
SqlCommand cmd = new SqlCommand(query, conn);
DataTable t1 = new DataTable();
using (SqlDataAdapter a = new SqlDataAdapter(cmd))
{
a.Fill(t1);
}
return t1;
}
and now can be used like this:
table = GetDataTable();
An other way which makes then your jsfiddle less buggy (needed double click on open).
This doesn't use any delegated event to body level
Set tabindex="-1"
to DIV .popup ( and for style CSS outline:0
)
$(".link").click(function(e){
e.preventDefault();
$(".popup").fadeIn(300,function(){$(this).focus();});
});
$('.close').click(function() {
$(".popup").fadeOut(300);
});
$(".popup").on('blur',function(){
$(this).fadeOut(300);
});
So, I had the same issue and sadly just adding to the rules didn't work. I found out that accept: and extension: are not part of JQuery validate.js by default and it requires an additional-Methods.js plugin to make it work.
So for anyone else who followed this thread and it still didn't work, you can try adding additional-Methods.js to your tag in addition to the answer above and it should work.
(This works at least up to version 1.52.0, 10 Dec 2020)
On macOS Visual Studio Code version 1.36.1 (2019)
To auto-format the selection, use ?K ?F (the trick is that this is to be done in sequence, ?K first, followed by ?F).
To just indent (shift right) without auto-formatting, use ?]
As in Keyboard Shortcuts (?K ?S, or from the menu as shown below)
Use like this:
when(
fooDao.getBar(
Matchers.<Bazoo>any()
)
).thenReturn(myFoo);
Before you need to import Mockito.Matchers
None of the above worked for me. Finally it wasn't anything related to any configuration.
I was getting the 404 error while trying to run a debug session through Visual Studio 2017 using the built in IISExpress 10.0. For me it was working when the release was published to the IIS server but getting a 404 when debugging locally through VS.
The issue turned out to be some old compiled files lying in the project bin directory which appeared to be interfering. Finally did a "Clean solution", closed VS, deleted the bin and obj folder. Restarted VS and rebuild project and the error went away.
Well for me only works adding the text "_helper"
after in the php file like:
And to load automatically the helper in the folder aplication -> file autoload.php add in the array helper's the name without "_helper" like:

And with that I can use all the helper's functions
I installed the LG United Mobile Driver, and I was finally able to get ADB to recognize my device.
I am not exactly sure which part to blame, but here's why MemoryStream
doesn't work for you:
As you write to MemoryStream
, it increments it's Position
property.
The constructor of StreamContent
takes into account the stream's current Position
. So if you write to the stream, then pass it to StreamContent
, the response will start from the nothingness at the end of the stream.
There's two ways to properly fix this:
1) construct content, write to stream
[HttpGet]
public HttpResponseMessage Test()
{
var stream = new MemoryStream();
var response = Request.CreateResponse(HttpStatusCode.OK);
response.Content = new StreamContent(stream);
// ...
// stream.Write(...);
// ...
return response;
}
2) write to stream, reset position, construct content
[HttpGet]
public HttpResponseMessage Test()
{
var stream = new MemoryStream();
// ...
// stream.Write(...);
// ...
stream.Position = 0;
var response = Request.CreateResponse(HttpStatusCode.OK);
response.Content = new StreamContent(stream);
return response;
}
2) looks a little better if you have a fresh Stream, 1) is simpler if your stream does not start at 0
1) Put https://api-server.com/API/index.php/member/signin
in the url input box and choose POST
from the dropdown
2) In Headers tab, enter:
Content-Type: image/jpeg
Content-Transfer-Encoding: binary
3) In Body tab, select the raw
radio button and write:
{"description":"","phone":"","lastname":"","app_version":"2.6.2","firstname":"","password":"my_pass","city":"","apikey":"213","lang":"fr","platform":"1","email":"[email protected]","pseudo":"example"}
select form-data
radio button and write:
key = name Value = userfile Select Text
key = filename Select File
and upload your profil.jpg
For NetBeans 8+ on Windows 10 there's a definitive bug with duplicate classes error which is being solved by cleaning the cache at
C:\Users\<user>\AppData\Local\NetBeans\Cache
.
Step 1 . Go to Androidsdk\platform-tools on PC/Laptop
Step 2 :
Connect your device via USB and run:
adb kill-server
then run
adb tcpip 5555
you will see below message...
daemon not running. starting it now on port 5037 * daemon started successfully * restarting in TCP mode port: 5555
Step3:
Now open new CMD window,
Go to Androidsdk\platform-tools
Now run
adb connect xx.xx.xx.xx:5555
(xx.xx.xx.xx is device IP)
Step4: Disconnect your device from USB and it will work as if connected from your Android studio.
I want to recommend go-spew, which according to their github "Implements a deep pretty printer for Go data structures to aid in debugging"
go get -u github.com/davecgh/go-spew/spew
usage example:
package main
import (
"github.com/davecgh/go-spew/spew"
)
type Project struct {
Id int64 `json:"project_id"`
Title string `json:"title"`
Name string `json:"name"`
Data string `json:"data"`
Commits string `json:"commits"`
}
func main() {
o := Project{Name: "hello", Title: "world"}
spew.Dump(o)
}
output:
(main.Project) {
Id: (int64) 0,
Title: (string) (len=5) "world",
Name: (string) (len=5) "hello",
Data: (string) "",
Commits: (string) ""
}
If you wrap one stream into another, you don't close intermediate streams, and very important: You don't close them before finishing using the outer streams. Because you would close the outer stream too.
If you want to really get only "path" without querystring, you can use url
library to parse and get only path part of url.
var url = require('url');
//auth required or redirect
app.use('/account', function(req, res, next) {
var path = url.parse(req.url).pathname;
if ( !req.session.user ) {
res.redirect('/login?ref='+path);
} else {
next();
}
});
You can access the local webserver which is running in your host machine in two ways.
Approach 1 with public IP
Use host machine public IP address to access webserver in Jenkins docker container.
Approach 2 with the host network
Use "--net host" to add the Jenkins docker container on the host's network stack. Containers which are deployed on host's stack have entire access to the host interface. You can access local webserver in docker container with a private IP address of the host machine.
NETWORK ID NAME DRIVER SCOPE
b3554ea51ca3 bridge bridge local
2f0d6d6fdd88 host host local
b9c2a4bc23b2 none null local
Start a container with the host network
Eg: docker run --net host -it ubuntu
and run ifconfig
to list all available network IP addresses which are reachable from docker container.
Eg: I started a nginx server in my local host machine and I am able to access the nginx website URLs from Ubuntu docker container.
docker run --net host -it ubuntu
$ docker ps

Normally, calling
var b = a.slice();
will copy the array a
into b
. However, we can't do
var a = arguments.slice();
because arguments
isn't a real array, and doesn't have slice
as a method. Array.prototype.slice
is the slice
function for arrays, and call
runs the function with this
set to arguments
.
Your bean or pojo class should implements parcelable interface
.
For example:
public class BeanClass implements Parcelable{
String name;
int age;
String sex;
public BeanClass(String name, int age, String sex) {
this.name = name;
this.age = age;
this.sex = sex;
}
public static final Creator<BeanClass> CREATOR = new Creator<BeanClass>() {
@Override
public BeanClass createFromParcel(Parcel in) {
return new BeanClass(in);
}
@Override
public BeanClass[] newArray(int size) {
return new BeanClass[size];
}
};
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeInt(age);
dest.writeString(sex);
}
}
Consider a scenario that you want to send the arraylist
of beanclass
type from Activity1
to Activity2
.
Use the following code
Activity1:
ArrayList<BeanClass> list=new ArrayList<BeanClass>();
private ArrayList<BeanClass> getList() {
for(int i=0;i<5;i++) {
list.add(new BeanClass("xyz", 25, "M"));
}
return list;

Activity2:

listFromActivity1=this.getIntent().getExtras().getParcelableArrayList("StudentDetails");
if (listFromActivity1 != null) {
Log.d("listis",""+listFromActivity1.toString());
}
I think this basic to understand the concept.
Take a look at the Collections.sort(List<T> list)
.
You can simply remove the first element, sort the list and then add it back again.
You can use the pointer-events
property in your CSS, and set it equal to 'none'
img {
pointer-events: none;
}
Edited
this will block (click) event. So better solution would be
<img draggable="false" (dragstart)="false;" class="unselectable">
.unselectable {
user-drag: none;
user-select: none;
-moz-user-select: none;
-webkit-user-drag: none;
-webkit-user-select: none;
-ms-user-select: none;
}
var el = document.getElementsByClassName('myclass')
el[0].classList.add('newclass');
el[0].classList.remove('newclass');
To find whether the class exists or not, use:
el[0].classList.contains('newclass'); // this will return true or false
Browser support IE8+
I know this thread is ancient, but after assigning the innerHTML, ExecWB worked for me:
.ExecWB 17, 0_x000D_
'Select all contents in browser_x000D_
.ExecWB 12, 2_x000D_
'Copy them
_x000D_
And then just paste the contents into Excel. Since these methods are prone to runtime errors, but work fine after one or two tries in debug mode, you might have to tell Excel to try again if it runs into an error. I solved this by adding this error handler to the sub, and it works fine:
Sub ApplyHTML()_x000D_
On Error GoTo ErrorHandler_x000D_
..._x000D_
Exit Sub_x000D_
_x000D_
ErrorHandler:_x000D_
Resume _x000D_
'I.e. re-run the line of code that caused the error_x000D_
Exit Sub_x000D_
_x000D_
End Sub
_x000D_
npm install ps-grab
node greeting.js --user Abdennour --website http://abdennoor.com
--
var grab=require('ps-grab');
grab('--username') // return 'Abdennour'
grab('--action') // return 'http://abdennoor.com'
Or something like :
node vbox.js -OS redhat -VM template-12332 ;
--
var grab=require('ps-grab');
grab('-OS') // return 'redhat'
grab('-VM') // return 'template-12332'
Increment a counter using admin.firestore.FieldValue.increment:
exports.onInstanceCreate = functions.firestore.document('projects/{projectId}/instances/{instanceId}')
.onCreate((snap, context) =>
db.collection('projects').doc(context.params.projectId).update({
instanceCount: admin.firestore.FieldValue.increment(1),
})
);
exports.onInstanceDelete = functions.firestore.document('projects/{projectId}/instances/{instanceId}')
.onDelete((snap, context) =>
db.collection('projects').doc(context.params.projectId).update({
instanceCount: admin.firestore.FieldValue.increment(-1),
})
);
In this example we increment an instanceCount
field in the project each time a document is added to the instances
sub collection. If the field doesn't exist yet it will be created and incremented to 1.
The incrementation is transactional internally but you should use a distributed counter if you need to increment more frequently than every 1 second.
It's often preferable to implement onCreate
and onDelete
rather than onWrite
as you will call onWrite
for updates which means you are spending more money on unnecessary function invocations (if you update the docs in your collection).
Install file loader first:
$ npm install file-loader --save-dev
And add this rule in webpack.config.js
{
test: /\.(png|jpg|gif)$/,
use: [{
loader: 'file-loader',
options: {}
}]
}
In my case (Oracle), it's WHERE REGEXP_LIKE(column, 'regex.*')
. See here:
SQL Function
Description
REGEXP_LIKE
This function searches a character column for a pattern. Use this function in the WHERE clause of a query to return rows matching the regular expression you specify.
...
REGEXP_REPLACE
This function searches for a pattern in a character column and replaces each occurrence of that pattern with the pattern you specify.
...
REGEXP_INSTR
This function searches a string for a given occurrence of a regular expression pattern. You specify which occurrence you want to find and the start position to search from. This function returns an integer indicating the position in the string where the match is found.
...
REGEXP_SUBSTR
This function returns the actual substring matching the regular expression pattern you specify.
(Of course, REGEXP_LIKE only matches queries containing the search string, so if you want a complete match, you'll have to use '^$'
for a beginning (^
) and end ($
) match, e.g.: '^regex.*$'
.)
A specification (blueprint) about how to make an OS compatible with late UNIX OS (may God bless him!). This is why macOS and GNU/Linux have very similar terminal command lines, GUI's, libraries, etc. Because they both were designed according to POSIX blueprint.
POSIX does not tell engineers and programmers how to code but what to code.
I ran into this error while trying to click some element (or its overlay, I didn't care), and the other answers didn't work for me. I fixed it by using the elementFromPoint
DOM API to find the element that Selenium wanted me to click on instead:
element_i_care_about = something()
loc = element_i_care_about.location
element_to_click = driver.execute_script(
"return document.elementFromPoint(arguments[0], arguments[1]);",
loc['x'],
loc['y'])
element_to_click.click()
I've also had situations where an element was moving, for example because an element above it on the page was doing an animated expand or collapse. In that case, this Expected Condition class helped. You give it the elements that are animated, not the ones you want to click. This version only works for jQuery animations.
class elements_not_to_be_animated(object):
def __init__(self, locator):
self.locator = locator
def __call__(self, driver):
try:
elements = EC._find_elements(driver, self.locator)
# :animated is an artificial jQuery selector for things that are
# currently animated by jQuery.
return driver.execute_script(
'return !jQuery(arguments[0]).filter(":animated").length;',
elements)
except StaleElementReferenceException:
return False
I spent about one day to configure the new gmaps API (Google Maps Android API v2) on the Android emulator. None of the methods of those I found on the Internet was working correctly for me. But still I did it. Here is how:
On the other versions I could not configure because of various errors when I installed the necessary applications.
2) Start the emulator and install the following applications:
You can do this with following commands:
2.1) adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock0 /system
2.2) adb shell chmod 777 /system/app
2.3-2.5) adb push Each_of_the_3_apk_files.apk /system/app/
Links to download APK files. I have copied them from my rooted Android device.
3) Install Google Play Services and Google Maps on the emulator. I have an error 491, if I install them from Google Play store. I uploaded the apps to the emulator and run the installation locally. (You can use adb
to install this). Links to the apps:
4) I successfully run a demo sample on the emulator after these steps. Here is a screenshot:
In this case, you could ( and probably would ) just define a Pizza base class and inherit from them. However, there are two reasons where Interfaces allow you to do things that cannot be achieved in other ways:
A class can implement multiple interfaces. It just defines features that the class must have. Implementing a range of interfaces means that a class can fulfil multiple functions in different places.
An interface can be defined in a hogher scope than the class or the caller. This means that you can separate the functionality, separate the project dependency, and keep the functionality in one project or class, and the implementation of this elsewhere.
One implication of 2 is that you can change the class that is being used, just requiring that it implements the appropriate interface.
I know it was not available at the time, but now you could also use Anaconda navigator to install a specific version of packages in the environments tab.
You can use openopt package and its NLP method. It has many dynamic programming algorithms to solve nonlinear algebraic equations consisting:
goldenSection, scipy_fminbound, scipy_bfgs, scipy_cg, scipy_ncg, amsg2p, scipy_lbfgsb, scipy_tnc, bobyqa, ralg, ipopt, scipy_slsqp, scipy_cobyla, lincher, algencan, which you can choose from.
Some of the latter algorithms can solve constrained nonlinear programming problem.
So, you can introduce your system of equations to openopt.NLP() with a function like this:
lambda x: x[0] + x[1]**2 - 4, np.exp(x[0]) + x[0]*x[1]
What I've found is that on top of setting the cell as selected, you have to let the table view know to select the row at the given index path.
// Swift 3+
override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
if appDelegate.indexPathDelegate.row == indexPath.row {
self.tableView.selectRow(at: indexPath, animated: true, scrollPosition: .none)
cell.setSelected(true, animated: true)
}
}
This is an old post but...
You can reference the working directory (the folder the .html file is located in) with ./
, and the directory above that with ../
Example directory structure:
/html/public/
- index.html
- script2.js
- js/
- script.js
To load script.js from inside index.html:
<script type="text/javascript" src="./js/script.js">
This goes to the current working directory (location of index.html) and then to the js folder, and then finds the script.
You could also specify ../
to go one directory above the working directory, to load things from there. But that is unusual.
Although prop changed the checked status but change also show that in the form.
$('input[name="correctAnswer"]').prop('checked', false).change();
First, it usually does not matter that much in practice. Most hash functions are "good enough".
But if you really care, you should know that it is a research subject by itself. There are thousand of papers about that. You can still get a PhD today by studying & designing hashing algorithms.
Your second hash function might be slightly better, because it probably should separate the string "ab"
from the string "ba"
. On the other hand, it is probably less quick than the first hash function. It may, or may not, be relevant for your application.
I'll guess that hash functions used for genome strings are quite different than those used to hash family names in telephone databases. Perhaps even some string hash functions are better suited for German, than for English or French words.
Many software libraries give you good enough hash functions, e.g. Qt has qhash, and C++11 has std::hash in <functional>
, Glib has several hash functions in C, and POCO has some hash function.
I quite often have hashing functions involving primes (see Bézout's identity) and xor, like e.g.
#define A 54059 /* a prime */
#define B 76963 /* another prime */
#define C 86969 /* yet another prime */
#define FIRSTH 37 /* also prime */
unsigned hash_str(const char* s)
{
unsigned h = FIRSTH;
while (*s) {
h = (h * A) ^ (s[0] * B);
s++;
}
return h; // or return h % C;
}
But I don't claim to be an hash expert. Of course, the values of A
, B
, C
, FIRSTH
should preferably be primes, but you could have chosen other prime numbers.
Look at some MD5 implementation to get a feeling of what hash functions can be.
Most good books on algorithmics have at least a whole chapter dedicated to hashing. Start with wikipages on hash function & hash table.
You can add a little white one with a Base64 Encoded GIF (online generator here):
url("data:image/gif;base64,R0lGODlhCwAKAIABAP////3cnSH5BAEKAAEALAAAAAALAAoAAAIUjH+AC73WHIsw0UCjglraO20PNhYAOw==")
With Chrome, for instance, I use it to style the checkbox control:
INPUT[type=checkbox]:focus
{
outline:1px solid rgba(0,0,0,0.2);
}
INPUT[type=checkbox]
{
background-color: #DDD;
border-radius: 2px;
-webkit-appearance: button;
width: 17px;
height: 17px;
margin-top: 1px;
cursor:pointer;
}
INPUT[type=checkbox]:checked
{
background:#409fd6 url("data:image/gif;base64,R0lGODlhCwAKAIABAP////3cnSH5BAEKAAEALAAAAAALAAoAAAIUjH+AC73WHIsw0UCjglraO20PNhYAOw==") 3px 3px no-repeat;
}
If you just wanted it in an IMG tag, you would do the checkmark/tickmark as:
<img alt="" src="data:image/gif;base64,R0lGODlhCwAKAIABAP////3cnSH5BAEKAAEALAAAAAALAAoAAAIUjH+AC73WHIsw0UCjglraO20PNhYAOw==" width="11" height="10">

I like checking the orientation notification because you can add this feature in any class, no needs to be a view or a view controller. Even in your app delegate.
SWIFT 5:
//ask the system to start notifying when interface change
UIDevice.current.beginGeneratingDeviceOrientationNotifications()
//add the observer
NotificationCenter.default.addObserver(
self,
selector: #selector(orientationChanged(notification:)),
name: UIDevice.orientationDidChangeNotification,
object: nil)
than caching the notification
@objc func orientationChanged(notification : NSNotification) {
//your code there
}
Try JSMin, got C#, Java, C and other ports and readily available too.
To the people who might be searching for this issue still, are looking at this page only.
This will help you remove cached index files, and then only add the ones you need, including changes to your .gitignore
file.
1. git rm -r --cached .
2. git add .
3. git commit -m 'Removing ignored files'
Here is a little bit more info.
- This command will remove all cached files from index.
- This command will add all files except those which are mentioned in
gitignore
.- This command will commit your files again and remove the files you want git to ignore, but keep them in your local directory.
Maximum number of elements of an array
is (2^31)-1
or 2 147 483 647
You have several techniques to do it.
This post - read the part about the revert will explain in details what we want to do and how to do it.
Here is the most simple solution to your problem:
# Checkout the desired branch
git checkout <branch>
# Undo the desired commit
git revert <commit>
# Update the remote with the undo of the code
git push origin <branch>
The revert command will create a new commit with the undo of the original commit.
Note that On Error Resume Next
is not set globally. You can put your unsafe part of code eg into a function, which will interrupted immediately if error occurs, and call this function from sub containing precedent OERN
statement.
ErrCatch()
Sub ErrCatch()
Dim Res, CurrentStep
On Error Resume Next
Res = UnSafeCode(20, CurrentStep)
MsgBox "ErrStep " & CurrentStep & vbCrLf & Err.Description
End Sub
Function UnSafeCode(Arg, ErrStep)
ErrStep = 1
UnSafeCode = 1 / (Arg - 10)
ErrStep = 2
UnSafeCode = 1 / (Arg - 20)
ErrStep = 3
UnSafeCode = 1 / (Arg - 30)
ErrStep = 0
End Function
As the only reliable source for domain suffixes are the domain registrars, you can't find the subdomain without their knowledge. There is a list with all domain suffixes at https://publicsuffix.org. This site also links to a PHP library: https://github.com/jeremykendall/php-domain-parser.
Please find an example below. I also added the sample for en.test.co.uk which is a domain with a multi suffix (co.uk).
<?php
require_once 'vendor/autoload.php';
$pslManager = new Pdp\PublicSuffixListManager();
$parser = new Pdp\Parser($pslManager->getList());
$host = 'http://en.example.com';
$url = $parser->parseUrl($host);
echo $url->host->subdomain;
$host = 'http://en.test.co.uk';
$url = $parser->parseUrl($host);
echo $url->host->subdomain;
I also tried to update a component from a jsf backing bean/class
You need to do the following after manipulating the UI component:
FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds().add(componentToBeRerendered.getClientId())
It is important to use the clientId instead of the (server-side) componentId!!
You can edit Rprofile
in the base
library (in 'C:/Program Files/R.Files/library/base/R'
by default) to include code to be run on startup. Append
######## User code ########
.libPaths('C:/my/dir')
to Rprofile
using any text editor (like Notepad) to cause R to add 'C:/my/dir'
to the list of libraries it knows about.
(Notepad can't save to Program Files, so save your edited Rprofile somewhere else and then copy it in using Windows Explorer.)
No arguments in DIVs favour from me.
I'd say : If the shoe fits, wear it.
It's worth noting that it's difficult if not impossible to find a good DIV+CSS method of rendering contents in two or three columns, that is consistent on all browsers, and still looks just the way I intended.
This tips the balance a bit towards tables in most of my layouts, and altough I feel guilty of using them (dunny why, people just say it's bad so I try to listen to them), in the end , the pragmatic view is it's just easier and faster for me to use TABLEs. I'm not being payed by the hour, so tables are cheaper for me.
You can run 20 processes and use the command:
wait
Your script will wait and continue when all your background jobs are finished.
Since C++ 17 (VS2015) you can use the standard for read-write locks:
#include <shared_mutex>
typedef std::shared_mutex Lock;
typedef std::unique_lock< Lock > WriteLock;
typedef std::shared_lock< Lock > ReadLock;
Lock myLock;
void ReadFunction()
{
ReadLock r_lock(myLock);
//Do reader stuff
}
void WriteFunction()
{
WriteLock w_lock(myLock);
//Do writer stuff
}
For older version, you can use boost with the same syntax:
#include <boost/thread/locks.hpp>
#include <boost/thread/shared_mutex.hpp>
typedef boost::shared_mutex Lock;
typedef boost::unique_lock< Lock > WriteLock;
typedef boost::shared_lock< Lock > ReadLock;
Javascript arrays have a length property. Use it like this:
st.itemb.length
Simply remove the dot for the relative import and do:
from p_02_paying_debt_off_in_a_year import compute_balance_after
AzP already provided most of the information, but some of it is incorrect.
First of all, there is no such option inotify_interval
. The only option that exists is notify_interval
and has nothing to do with inotify
.
So to clarify, notify_interval
controls how frequently the (mini)dlna server announces itself in the network. The default value of 895 means it will announce itself about once every 15 minutes, meaning clients will need at most 15 minutes to find the server. I personally use 1-5 minutes depending on client volatility in the network.
In terms of getting minidlna to find files that have been added, there are two options:
files.db
and consists in restarting minidlna while passing the -R
argument, which forces a full rescan and builds the database from scratch. Since version 1.2.0 there's now also the -r
argument which performs a rebuild action. This preserves any existing database and drops and adds old and new records, respectively.inotify
events by setting inotify=yes
and restarting minidlna. If inotify
is set to =no
, the only option to update the file database is the forced full rescan.Additionally, in order to have inotify
working, the file-system must support inotify
events, which is not the case in most remote file-systems. If you have minidlna running over NFS it will not see any inotify events because these are generated on the server side and not on the client.
Finally, even if inotify
is working and is supported by the file-system, the user under which minidlna is running must be able to read the file, otherwise it will not be able to retrieve necessary metadata. In this case, the logfile (usually /var/log/minidlna.log
) should contain useful information.
@Cebjyre. The IDE whether Enterprise Manager or Management Studio is better than anything I have seen so far for MySQL. I say 'easier to use' because I can do many things in MSSQL where MySQL has no counterparts. In MySQL I have no idea how to tune the queries by simply looking at the query plan or looking at the statistics. The index tuning wizard in MSSQL takes most of the guess work on what indexes are missing or misplaced.
One shortcoming of MySQL is there's no max size for a database. The database would just increase in size till it fills up the disk. Imagine if this disk is sharing databases with other users and suddenly all of their queries are failing because their databases can't grow. I have reported this issue to MySQL long time ago. I don't think it's fixed yet.
Something like this?
And the code I used:
.box{
position: relative;
overflow: hidden;
}
.box:hover .hidden{
left: 0px;
}
.box .hidden {
background: yellow;
height: 300px;
position: absolute;
top: 0;
left: -500px;
width: 500px;
opacity: 1;
-webkit-transition: all 0.7s ease-out;
-moz-transition: all 0.7s ease-out;
-ms-transition: all 0.7s ease-out;
-o-transition: all 0.7s ease-out;
transition: all 0.7s ease-out;
}
I may also add that it's possible to move an elment using transform: translate();
, which in this case could work something like this - DEMO nr2
Sadly the other posters are correct that you're
...actually as corrected by kRON, you are ok with your IE7 and a strict doc, but most of us with IE6 requirements are reduced to JS or class references for this, but it is a CSS2 property, just one without sufficient support from IE^h^h browsers.
Out of completeness, the type selector is - similar to xpath - of the form [attribute=value]
but many interesting variants exist. It will be quite powerful when it's available, good thing to keep in your head for IE8.

this code will work with OI File Manager :
File root = new File(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
Uri uri = Uri.fromFile(root);
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setData(uri);
startActivityForResult(intent, 1);

After Php 7.1, The accepted answer won't work for all types of relationships.
Because depending of type the relationship, Eloquent will return a Collection
, a Model
or Null
. And in Php 7.1 count(null)
will throw an error
.
So, to check if the relation exist you can use:
For relationships single: For example hasOne
and belongsTo
if(!is_null($model->relation)) {
....
}
For relationships multiple: For Example: hasMany
and belongsToMany
if ($model->relation->isNotEmpty()) {
....
}
I wrote a function which solves the problem precisely.
First argument is the string that wanted to be parameterized. You should put your variables in this string like this format "%s1, %s2, ... %s12".
Other arguments are the parameters respectively for that string.
/***
* @example parameterizedString("my name is %s1 and surname is %s2", "John", "Doe");
* @return "my name is John and surname is Doe"
*
* @firstArgument {String} like "my name is %s1 and surname is %s2"
* @otherArguments {String | Number}
* @returns {String}
*/
const parameterizedString = (...args) => {
const str = args[0];
const params = args.filter((arg, index) => index !== 0);
if (!str) return "";
return str.replace(/%s[0-9]+/g, matchedStr => {
const variableIndex = matchedStr.replace("%s", "") - 1;
return params[variableIndex];
});
}
Examples
parameterizedString("my name is %s1 and surname is %s2", "John", "Doe");
// returns "my name is John and surname is Doe"
parameterizedString("this%s1 %s2 %s3", " method", "sooo", "goood");
// returns "this method sooo goood"
If variable position changes in that string, this function supports it too without changing the function parameters.
parameterizedString("i have %s2 %s1 and %s4 %s3.", "books", 5, "pencils", "6");
// returns "i have 5 books and 6 pencils."
If you are talking about a browser based POS app then it basically can't be done out of the box. There are a number of alternatives.
To Download Specific Branch - Go To Downloads from Left panel, Select Branches on Downloads page. It will list all Branches available. Download your desired branch in zip, gz, or bz2 format.
Just use this:
var date_str=('0'+date.getDate()).substr(-2,2)+' '+('0'+date.getMonth()).substr(-2,2)+' '+('0'+date.getFullYear()).substr(-2,2);
In my case,
modal-lg
class was not wide enough.so the solution was
@media (min-width: 1200px) {
.modal-xlg {
width: 90%;
}
}
and use the above class instead of modal-lg
class
Alternatively You can use the brew or curl command for installing things, wherever apt-get is mentioned with a URL...
For example,
curl -O http://www.magentocommerce.com/downloads/assets/1.8.1.0/magento-1.8.1.0.tar.gz
That's what I do in Opencv to detect focus quality in a region:
Mat grad;
int scale = 1;
int delta = 0;
int ddepth = CV_8U;
Mat grad_x, grad_y;
Mat abs_grad_x, abs_grad_y;
/// Gradient X
Sobel(matFromSensor, grad_x, ddepth, 1, 0, 3, scale, delta, BORDER_DEFAULT);
/// Gradient Y
Sobel(matFromSensor, grad_y, ddepth, 0, 1, 3, scale, delta, BORDER_DEFAULT);
convertScaleAbs(grad_x, abs_grad_x);
convertScaleAbs(grad_y, abs_grad_y);
addWeighted(abs_grad_x, 0.5, abs_grad_y, 0.5, 0, grad);
cv::Scalar mu, sigma;
cv::meanStdDev(grad, /* mean */ mu, /*stdev*/ sigma);
focusMeasure = mu.val[0] * mu.val[0];
An alternative solution, which is portable and with higher precision, available since C++11, is to use std::chrono
.
Here is an example:
#include <iostream>
#include <chrono>
typedef std::chrono::high_resolution_clock Clock;
int main()
{
auto t1 = Clock::now();
auto t2 = Clock::now();
std::cout << "Delta t2-t1: "
<< std::chrono::duration_cast<std::chrono::nanoseconds>(t2 - t1).count()
<< " nanoseconds" << std::endl;
}
Running this on ideone.com gave me:
Delta t2-t1: 282 nanoseconds
I had the same problem with "document.cookie" in Windows 8.1, the only way that Chrome deletes the cookie was shutting it from task manager (not a really fancy way), so I decided to manage the cookies from the backend or use something like "js-cookie".
As pointed out in answers above
my_string.strip()
will remove all the leading and trailing whitespace characters such as \n
, \r
, \t
, \f
, space
.
For more flexibility use the following
my_string.lstrip()
my_string.rstrip()
my_string.strip('\n')
or my_string.lstrip('\n\r')
or my_string.rstrip('\n\t')
and so on.More details are available in the docs.
Ruby's .strip
method performs the PHP equivalent to trim()
.
To remove all whitespace:
" leading trailing ".squeeze(' ').strip
=> "leading trailing"
@Tass made me aware that my original answer removes duplicate letters in succession - YUCK! I've since switched to the squish method which is smarter about such occurrences if using the Rails framework.
require 'active_support/all'
" leading trailing ".squish
=> "leading trailing"
" good men ".squish

Use Reader.read(). A return value of -1 means end of stream; else, cast to char.
This code reads character data from a list of file arguments:
public class CharacterHandler {
//Java 7 source level
public static void main(String[] args) throws IOException {
// replace this with a known encoding if possible
Charset encoding = Charset.defaultCharset();
for (String filename : args) {
File file = new File(filename);
handleFile(file, encoding);
}
}
private static void handleFile(File file, Charset encoding)
throws IOException {
try (InputStream in = new FileInputStream(file);
Reader reader = new InputStreamReader(in, encoding);
// buffer for efficiency
Reader buffer = new BufferedReader(reader)) {
handleCharacters(buffer);
}
}
private static void handleCharacters(Reader reader)
throws IOException {
int r;
while ((r = reader.read()) != -1) {
char ch = (char) r;
System.out.println("Do something with " + ch);
}
}
}
The bad thing about the above code is that it uses the system's default character set. Wherever possible, prefer a known encoding (ideally, a Unicode encoding if you have a choice). See the Charset class for more. (If you feel masochistic, you can read this guide to character encoding.)
(One thing you might want to look out for are supplementary Unicode characters - those that require two char values to store. See the Character class for more details; this is an edge case that probably won't apply to homework.)
This work perfectly! ;)
This can be done using Ajax and with what I call: "a form mirror element". Instead to send a form with an element outside, you can create a fake form. The previous form is not needed.
<!-- This will do the trick -->
<div >
<input id="mirror_element" type="text" name="your_input_name">
<input type="button" value="Send Form">
</div>
Code ajax would be like:
<script>
ajax_form_mirror("#mirror_element", "your_file.php", "#your_element_response", "POST");
function ajax_form_mirror(form, file, element, method) {
$(document).ready(function() {
// Ajax
$(form).change(function() { // catch the forms submit event
$.ajax({ // create an AJAX call...
data: $(this).serialize(), // get the form data
type: method, // GET or POST
url: file, // the file to call
success: function (response) { // on success..
$(element).html(response); // update the DIV
}
});
return false; // cancel original event to prevent form submitting
});
});
}
</script>
This is very usefull if you want to send some data inside another form without submit the parent form.
This code probably can be adapted/optimized according to the need. It works perfectly!! ;) Also works if you want a select option box like this:
<div>
<select id="mirror_element" name="your_input_name">
<option id="1" value="1">A</option>
<option id="2" value="2">B</option>
<option id="3" value="3">C</option>
<option id="4" value="4">D</option>
</select>
</div>
I hope it helped someone like it helped me. ;)
I'm using a workaround by returning a function with an object of my global variables:
function globalVariables(){
var variables = {
sheetName: 'Sheet1',
variable1: 1,
variable2: 2
};
return variables;
}
function functionThatUsesVariable (){
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(globalVariables().sheetName);
}
Internet Explorer 8 (and earlier versions) doesn't support rounded corners, however there are few other solutions you may consider:
Use Rounded Corners Images
instead (this generator is a good resource)
Use a jQuery Corner plugin
from here
Use a very good script called CSS3 PIE
from here (Pro's & Con's here)
Checkout CSS Juice
from here
Another good script is IE-CSS3
from here
Even though CSS PIE is the most popular solution, I'm suggesting you to review all other solutions and choose what works best for your needs.
Hope it was useful. Good Luck!
You can use the getName()
method of FragmentManager.BackStackEntry
which was introduced in API level 14. This method will return a tag which was the one you used when you added the Fragment to the backstack with addTobackStack(tag)
.
int index = getActivity().getFragmentManager().getBackStackEntryCount() - 1
FragmentManager.BackStackEntry backEntry = getFragmentManager().getBackStackEntryAt(index);
String tag = backEntry.getName();
Fragment fragment = getFragmentManager().findFragmentByTag(tag);
You need to make sure that you added the fragment to the backstack like this:
fragmentTransaction.addToBackStack(tag);
You will need to melt
your dataframe to get it into the so-called long format:
require(reshape2)
sample.data.M <- melt(sample.data)
Now your field values are represented by their own rows and identified through the variable column. This can now be leveraged within the ggplot aesthetics:
require(ggplot2)
c <- ggplot(sample.data.M, aes(x = Rank, y = value, fill = variable))
c + geom_bar(stat = "identity")
Instead of stacking you may also be interested in showing multiple plots using facets:
c <- ggplot(sample.data.M, aes(x = Rank, y = value))
c + facet_wrap(~ variable) + geom_bar(stat = "identity")
If you have a keyboard layout that requires you to also press the shift key (i.e. cmd + shift + 7 on a German keyboard), the shortcut won't work and open the help menu, instead.
Apple's "Think Different" in its fullest extent ...

Well, the shortest way I know of, is following:
psql -U {user_name} -d {database_name} -f {file_path} -h {host_name}
database_name: Which database should you insert your file data in.
file_path: Absolute path to the file through which you want to perform the importing.
host_name: The name of the host. For development purposes, it is mostly localhost
.
Upon entering this command in console, you will be prompted to enter your password.
The following code is a modified example from React.js website.
Original code is available here: https://reactjs.org/#a-simple-component
class Timer extends React.Component {
constructor(props) {
super(props);
this.state = {
seconds: parseInt(props.startTimeInSeconds, 10) || 0
};
}
tick() {
this.setState(state => ({
seconds: state.seconds + 1
}));
}
componentDidMount() {
this.interval = setInterval(() => this.tick(), 1000);
}
componentWillUnmount() {
clearInterval(this.interval);
}
formatTime(secs) {
let hours = Math.floor(secs / 3600);
let minutes = Math.floor(secs / 60) % 60;
let seconds = secs % 60;
return [hours, minutes, seconds]
.map(v => ('' + v).padStart(2, '0'))
.filter((v,i) => v !== '00' || i > 0)
.join(':');
}
render() {
return (
<div>
Timer: {this.formatTime(this.state.seconds)}
</div>
);
}
}
ReactDOM.render(
<Timer startTimeInSeconds="300" />,

Perhaps not what the OP was after, but for those searching the URL to simply access a readable object on S3 is more like:
https://<region>.amazonaws.com/<bucket-name>/<key>
Where <region>
is something like s3-ap-southeast-2
.
Click on the item in the S3 GUI to get the link for your bucket.
Easiest way would probably be with jQuery, as follows:
$(document).ready(function(){
$("#_1234").attr("checked","checked");
})
This adds a new attribute "checked" (which in HTML does not need a value). Just remember to include the jQuery library:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
How do I create PDF's in FPDF that support Chinese, Japanese, Russian, etc.?
(snapshots of code in use below)
I'd like to provide: a summary of the problem, the solution, a github project with the working code, and an online example with the expected, resultant PDF.
The Problem :
You actually need a font that supports the UTF-8 characters you are using.
I.E., merely using Helvetica and trying to display Japanese will not work. If you use Font Forge, or some other font tool, you can scroll to the Chinese characters of the font, and see that they are blank.
Google has a font (Noto font) that contains all languages, and it is 20mb, which is usually several factors the size of your text. So, you can see why many fonts simply won't cover every single language.
The Solution :
I'm using rounded-mgenplus-20140828.ttf and ZCOOL_QingKe_HuangYou.ttf font packs for Japanese and Chinese, which are open source and can be found in many open source projects. In tFPDF itself, or a new inheriting class of it, like class HTMLtoPDF extends tFPDF {...}
, you'll do this...
$this->AddFont('japanese', '', 'rounded-mgenplus-20140828.ttf', true);
$this->SetFont('japanese', '', 14);
$this->Write(14, '???');
Should be nothing more to it!

Here is how to split one commit in IntelliJ IDEA, PyCharm, PhpStorm etc
In Version Control log window, select the commit you would like to
split, right click and select the Interactively Rebase from Here
mark the one you want to split as edit
, click Start
Rebasing
You should see a yellow tag is placed meaning that the HEAD is set
to that commit. Right click on that commit, select Undo Commit
Now those commits are back to staging area, you can then commit them separately. After all change has been committed, the old commit becomes inactive.
To get the path of all images in android I am using following code
public void allImages()
{
ContentResolver cr = getContentResolver();
Cursor cursor;
Uri allimagessuri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Images.Media._ID + " != 0";
cursor = cr.query(allsongsuri, STAR, selection, null, null);
if (cursor != null) {
if (cursor.moveToFirst()) {
do {
String fullpath = cursor.getString(cursor
.getColumnIndex(MediaStore.Images.Media.DATA));
Log.i("Image path ", fullpath + "");
} while (cursor.moveToNext());
}
cursor.close();
}
}
If you are only looking for images and multiple selection.
Look @ once https://stackoverflow.com/a/15029515/1136023
It's helpful for future.I personally feel great by using MultipleImagePick.
use .any()
if numpy.isnan(myarray).any()
numpy.isfinite maybe better than isnan for checking
if not np.isfinite(prop).all()
You can declare a dictionary inside a dictionary by nesting the {} containers:
d = {'dict1': {'foo': 1, 'bar': 2}, 'dict2': {'baz': 3, 'quux': 4}}
And then you can access the elements using the [] syntax:
print d['dict1'] # {'foo': 1, 'bar': 2}
print d['dict1']['foo'] # 1
print d['dict2']['quux'] # 4
Given the above, if you want to add another dictionary to the dictionary, it can be done like so:
d['dict3'] = {'spam': 5, 'ham': 6}
or if you prefer to add items to the internal dictionary one by one:
d['dict4'] = {}
d['dict4']['king'] = 7
d['dict4']['queen'] = 8
I had to use Debug.print
instead of Print
, which works in the Immediate window.

The simpliest and elegant solution for me:

form.myButton.disabled = true;
form.myButton.value = "Please wait...";
return true;
}
<form method="POST" action="..." onsubmit="return checkForm(this);">

docker stop $(docker ps -a | grep "zalenium")
docker rm $(docker ps -a | grep "zalenium")
This should be enough.
when you are dealing with popups window.opener plays an important role, because we have to deal with fields of parent page as well as child page, when we have to use values on parent page we can use window.opener or we want some data on the child window or popup window at the time of loading then again we can set the values using window.opener
List<String> list = new ArrayList<String>(listOfTopicAuthors);
There's no general way to tell if a file is encoded with a specific encoding. Remember that an encoding is nothing more but an "agreement" how the bits in a file should be mapped to characters.
If you don't know which of your files are actually already encoded in UTF-8 and which ones are encoded in windows-1252, you will have to inspect all files and find out yourself. In the worst case that could mean that you have to open every single one of them with either of the two encodings and see whether they "look" correct -- i.e., all characters are displayed correctly. Of course, you may use tool support in order to do that, for instance, if you know for sure that certain characters are contained in the files that have a different mapping in windows-1252 vs. UTF-8, you could grep for them after running the files through 'iconv' as mentioned by Seva Akekseyev.
Another lucky case for you would be, if you know that the files actually contain only characters that are encoded identically in both UTF-8 and windows-1252. In that case, of course, you're done already.
We use WinSCP. Its free. Its not a lib, but has a well documented and full featured command line interface that you can use with Process.Start.
Update: with v.5.0, WinSCP has a .NET wrapper library to the scripting layer of WinSCP.
You needed to iconv your source.
That said, the TEX-based compiler invoked by latex
doesn't really support variable-length encodings; it needs big libraries that tell it that certain bytes go together. Xelatex is Unicode-aware and works much better.
(Kotlin) In the activity hosting the fragment(s):
override fun onOptionsItemSelected(item: MenuItem): Boolean {
when (item.itemId) {
android.R.id.home -> {
onBackPressed()
return true
}
}
return super.onOptionsItemSelected(item)
}
I have found that when I add fragments to a project, they show the action bar home button by default, to remove/disable it put this in onViewCreated() (use true to enable it if it is not showing):
val actionBar = this.requireActivity().actionBar
actionBar?.setDisplayHomeAsUpEnabled(false)
Yes it is, and you can also use it like this
<button>Click here to<br/> start playing</button>
if you want to make the break yourself.
SELECT *
FROM my_table
WHERE substr(my_field,1,5) = "abcde";
The answer is opinion. I worked in a lot of projects and being testmanager and issuemanager and all different roles and the descriptions in various books differ so here is my variation:
functional-testing: take the business requirements and test all of it good and thorougly from a functional viewpoint.
acceptance-testing: the "paying" customer does the testing he likes to do so that he can accept the product delivered. It depends on the customer but usually the tests are not as thorough as the functional-testing especially if it is an in-house project because the stakeholders review and trust the test results done in earlier test phases.
As I said this is my viewpoint and experience. The functional-testing is systematic and the acceptance-testing is rather the business department testing the thing.

Try the Python scp module for Paramiko. It's very easy to use. See the following example:
import paramiko
from scp import SCPClient
def createSSHClient(server, port, user, password):
client = paramiko.SSHClient()
client.load_system_host_keys()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(server, port, user, password)
return client
ssh = createSSHClient(server, port, user, password)
scp = SCPClient(ssh.get_transport())
Then call scp.get()
or scp.put()
to do SCP operations.
Fixed!
The reason was the dbpath
variable in /etc/mongodb.conf
.
Previously, I was using mongodb 1.8, where the default value for dbpath was /data/db
.
The upstart job mongodb
(which comes with mongodb-10gen package) invokes the mongod
with --config /etc/mongodb.conf
option.
As a solution, I only had to change the owner of the /data/db
directory recursively.
I just had the same problem and ended up doing:
git rebase -i HEAD~N
(N is the number of commits git will show you)
That prompts your text editor and then you can remove the commit you want by deleting the line associated with it.
I did this using a solution similar to @ZuzEL.
Instead of use the default solution (http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=7|FF0000|000000), you can create these images as you wish, using JavaScript, without any server-side code.
Google google.maps.Marker accepts Base64 for its icon property. With this we can create a valid Base64 from a SVG.
You can see the code to produce the same as this image in this Plunker: http://plnkr.co/edit/jep5mVN3DsVRgtlz1GGQ?p=preview

In this demo I create the SVG using D3.js, then transformed SVG to Canvas, so I can resize the image as I want and after that I get Base64 from canvas' toDataURL method.
All this demo was based on my fellow @thiago-mata code. Kudos for him.
A much easier way to do this is using PowerShell, like so:
Get-Website yoursite | % { Join-Path ($_.logFile.Directory -replace '%SystemDrive%', $env:SystemDrive) "W3SVC$($_.id)" }
or simply
Get-Website yoursite | % { $_.logFile.Directory, $_.id }
if you just need the info for yourself and don't mind parsing the result in your brain :).
For bonus points, append | ii
to the first command to open in Explorer, or | gci
to list the contents of the folder.

If your code has add(0)
and remove(0)
, use a LinkedList
and it's prettier addFirst()
and removeFirst()
methods. Otherwise, use ArrayList
.
And of course, Guava's ImmutableList is your best friend.
you'd use another join, something along these lines:
SELECT toD.dom_url AS ToURL,
fromD.dom_url AS FromUrl,
rvw.*
FROM reviews AS rvw
LEFT JOIN domain AS toD
ON toD.Dom_ID = rvw.rev_dom_for
LEFT JOIN domain AS fromD
ON fromD.Dom_ID = rvw.rev_dom_from
EDIT:
All you're doing is joining in the table multiple times. Look at the query in the post: it selects the values from the Reviews tables (aliased as rvw), that table provides you 2 references to the Domain table (a FOR and a FROM).
At this point it's a simple matter to left join the Domain table to the Reviews table. Once (aliased as toD) for the FOR, and a second time (aliased as fromD) for the FROM.
Then in the SELECT list, you will select the DOM_URL fields from both LEFT JOINS of the DOMAIN table, referencing them by the table alias for each joined in reference to the Domains table, and alias them as the ToURL and FromUrl.

Here's my workaround:
I created a library with Angular 6. I added a common component commonlib-header
which is used like this in an external application.
Note the serviceReference
which is the class (injected in the component constructor(public serviceReference: MyService)
that uses the commonlib-header
) that holds the stringFunctionName
method:
<commonlib-header
[logo]="{ src: 'assets/img/logo.svg', alt: 'Logo', href: '#' }"
[buttons]="[{ index: 0, innerHtml: 'Button', class: 'btn btn-primary', onClick: [serviceReference, 'stringFunctionName', ['arg1','arg2','arg3']] }]">
</common-header>
The library component is programmed like this. The dynamic event is added in the onClick(fn: any)
method:
export class HeaderComponent implements OnInit {
_buttons: Array<NavItem> = []
@Input()
set buttons(buttons: Array<any>) {
buttons.forEach(navItem => {
let _navItem = new NavItem(navItem.href, navItem.innerHtml)
_navItem.class = navItem.class
_navItem.onClick = navItem.onClick // this is the array from the component @Input properties above
this._buttons[navItem.index] = _navItem
})
}
constructor() {}
ngOnInit() {}
onClick(fn: any){
let ref = fn[0]
let fnName = fn[1]
let args = fn[2]
ref[fnName].apply(ref, args)
}
The reusable header.component.html
:
<div class="topbar-right">
<button *ngFor="let btn of _buttons"
class="{{ btn.class }}"
(click)="onClick(btn.onClick)"
[innerHTML]="btn.innerHtml | keepHtml"></button>
</div>
VB Version:
Class:
Protected divControl As System.Web.UI.HtmlControls.HtmlGenericControl
OnLoad/Other function:
divControl.Style("height") = "200px"
I've never tried the Add method with the styles. What if the height already exists on the DIV?
Here is a simple way using ExtractToDirectory from System.IO.Compression.ZipFile:
Add-Type -AssemblyName System.IO.Compression.FileSystem
function Unzip
{
param([string]$zipfile, [string]$outpath)
[System.IO.Compression.ZipFile]::ExtractToDirectory($zipfile, $outpath)
}
Unzip "C:\a.zip" "C:\a"
Note that if the target folder doesn't exist, ExtractToDirectory will create it. Other caveats:

You can specify the interpretation order of the axes using the order
parameter:

You've declared the class Thing
as a non-static inner class. That means it must be associated with an instance of the Hello
class.
In your code, you're trying to create an instance of Thing
from a static context. That is what the compiler is complaining about.
There are a few possible solutions. Which solution to use depends on what you want to achieve.
Move Thing
out of the Hello
class.
Change Thing
to be a static
nested class.
static class Thing
Create an instance of Hello
before creating an instance of Thing
.
public static void main(String[] args)
{
Hello h = new Hello();
Thing thing1 = h.new Thing(); // hope this syntax is right, typing on the fly :P
}
The last solution (a non-static nested class) would be mandatory if any instance of Thing
depended on an instance of Hello
to be meaningful. For example, if we had:
public class Hello {
public int enormous;
public Hello(int n) {
enormous = n;
}
public class Thing {
public int size;
public Thing(int m) {
if (m > enormous)
size = enormous;
else
size = m;
}
}
...
}
any raw attempt to create an object of class Thing
, as in:
Thing t = new Thing(31);
would be problematic, since there wouldn't be an obvious enormous
value to test 31 against it. An instance h
of the Hello
outer class is necessary to provide this h.enormous
value:
...
Hello h = new Hello(30);
...
Thing t = h.new Thing(31);
...
Because it doesn't mean a Thing
if it doesn't have a Hello
.

If you need it to work on both Mac and Windows, you can use QueryTables:
With ActiveSheet.QueryTables.Add(Connection:="URL;http://carbon.brighterplanet.com/flights.txt", Destination:=Range("A2"))
.PostText = "origin_airport=MSN&destination_airport=ORD"
.RefreshStyle = xlOverwriteCells
.SaveData = True
.Refresh
End With
Notes:
For more details, you can see my full summary about "using web services from Excel."
Strings are immutable, meaning their contents cannot change. When you call replace(this,that)
you end up with a totally new String. If you want to keep this new copy, you need to assign it to a variable. You can overwrite the old reference (a la sentence = sentence.replace(this,that)
or a new reference as seen below:
public class Test{
public static void main(String[] args) {
String sentence = "Define, Measure, Analyze, Design and Verify";
String replaced = sentence.replace("and", "");
System.out.println(replaced);
}
}
As an aside, note that I've removed the contains()
check, as it is an unnecessary call here. If it didn't contain it, the replace will just fail to make any replacements. You'd only want that contains method if what you're replacing was different than the actual condition you're checking.
Actually you can do this with:
ssl off;
This solved my problem in using nginxvhosts; now I am able to use both SSL and plain HTTP. Works even with combined ports.
This example is for working with .xlsx file types. This example comes from a .jsp page used to create a .xslx spreadsheet.
import org.apache.poi.xssf.usermodel.*; //import needed
XSSFWorkbook wb = new XSSFWorkbook (); // Create workbook
XSSFSheet sheet = wb.createSheet(); // Create spreadsheet in workbook
XSSFRow row = sheet.createRow(rowIndex); // Create the row in the spreadsheet
//1. Create the date cell style
XSSFCreationHelper createHelper = wb.getCreationHelper();
XSSFCellStyle cellStyle = wb.createCellStyle();
cellStyle.setDataFormat(
createHelper.createDataFormat().getFormat("MMMM dd, yyyy"));
//2. Apply the Date cell style to a cell
//This example sets the first cell in the row using the date cell style
cell = row.createCell(0);
cell.setCellValue(new Date());
cell.setCellStyle(cellStyle);
In spite of all the answers you already received, it is worth noting that you do not need to write a plugin to use jQuery in a function. Certainly if it's a simple, one-time function, I believe writing a plugin is overkill. It could be done much more easily by just passing the selector to the function as a parameter. Your code would look something like this:
function myFunction($param) {
$param.hide(); // or whatever you want to do
...
}
myFunction($('#my_div'));
Note that the $
in the variable name $param
is not required. It is just a habit of mine to make it easy to remember that that variable contains a jQuery selector. You could just use param
as well.
The
<body oncontextmenu="return false;">
no longer works. Chrome and Opera as of June 2018 has a submenu on the timeline to allow straight download, so user doesn't need to right click to download that video. Interestingly Firefox and Edge don't have this ...
the syntax is CONSTRAINT constraint_name PRIMARY KEY(col1,col2,col3)
for example ::
CONSTRAINT pk_PersonID PRIMARY KEY (P_Id,LastName)
the above example will work if you are writting it while you are creating the table for example ::
CREATE TABLE person (
P_Id int ,
............,
............,
CONSTRAINT pk_PersonID PRIMARY KEY (P_Id,LastName)
);
to add this constraint to an existing table you need to follow the following syntax
ALTER TABLE table_name ADD CONSTRAINT constraint_name PRIMARY KEY (P_Id,LastName)
If you did all and it didn't work again like mien, do this copy Image.py and ImageTk.py from /usr/lib/python3/dist-packages/PIL on ubuntu and C:/Users/yourComputerName/AppData/Local/Programs/Python/Python36/Lib/PIL on windows to your projects directory and just import them!
this error is also caused by null pointer reference. if you are using a pointer who is not initialized then it causes this error.
to check either a pointer is initialized or not you can try something like
Class *pointer = new Class();
if(pointer!=nullptr){
pointer->myFunction();
}
64 bit version will allow a single process to use more RAM than 32 bit, however you may find that the memory footprint doubles depending on what you are storing in RAM (Integers in particular).
For example if your app requires > 2GB of RAM, so you switch from 32bit to 64bit you may find that your app is now requiring > 4GB of RAM.
Check whether all of your 3rd party modules are available in 64 bit, otherwise it may be easier to stick to 32bit in the meantime
Java Escape Sequences:
\u{0000-FFFF} /* Unicode [Basic Multilingual Plane only, see below] hex value
does not handle unicode values higher than 0xFFFF (65535),
the high surrogate has to be separate: \uD852\uDF62
Four hex characters only (no variable width) */
\b /* \u0008: backspace (BS) */
\t /* \u0009: horizontal tab (HT) */
\n /* \u000a: linefeed (LF) */
\f /* \u000c: form feed (FF) */
\r /* \u000d: carriage return (CR) */

\\ /* \u005c: backslash (\) */
\{0-377} /* \u0000 to \u00ff: from octal value

The Basic Multilingual Plane is the unicode values from 0x0000 - 0xFFFF (0 - 65535). Additional planes can only be specified in Java by multiple characters: the egyptian heiroglyph A054 (laying down dude) is U+1303F
/ 𓀿
and would have to be broken into "\uD80C\uDC3F"
(UTF-16) for Java strings. Some other languages support higher planes with "\U0001303F"

Set implicit wait immediately after creating the web driver instance:
_ = driver.Manage().Timeouts().ImplicitWait;
This will try to wait until the page is fully loaded on every page navigation or page reload.
After page navigation, call JavaScript return document.readyState
until "complete"
is returned. The web driver instance can serve as JavaScript executor. Sample code:
C#
new WebDriverWait(driver, MyDefaultTimeout).Until(
d => ((IJavaScriptExecutor) d).ExecuteScript("return document.readyState").Equals("complete"));
Java
new WebDriverWait(firefoxDriver, pageLoadTimeout).until(
webDriver -> ((JavascriptExecutor) webDriver).executeScript("return document.readyState").equals("complete"));
Check if the URL matches the pattern you expect.
The question is how to create a new virtual environment in VSCode, that is why telling the following Anaconda solution might not the needed answer to the question. It is just relevant for Anaconda users.
Just create a venv using conda, see here. Afterwards open VSCode and left-click on the VSCode interpreter shown in VSCode at the bottom left:
Choose a virtual environment that pops up in a dropdown of the settings window, and you are done. Mind the answer of @RamiMa.
Here is the solution I found on Hibernate 4.1.9. I had to pass a parameter to my query that can have value NULL sometimes. So I passed the using:
setParameter("orderItemId", orderItemId, new LongType())
After that, I use the following where clause in my query:
where ((:orderItemId is null) OR (orderItem.id != :orderItemId))
As you can see, I am using the Query.setParameter(String, Object, Type) method, where I couldn't use the Hibernate.LONG that I found in the documentation (probably that was on older versions). For a full set of options of type parameter, check the list of implementation class of org.hibernate.type.Type interface.
Hope this helps!
You need to set a few extra flags so that curl sends the data as JSON.

Put the FrameLayout in LinearLayout and set orientation to Horizontal.
The answers above don't cover how to cleanly deal with a connection that has timed out. Calling TcpClient.EndConnect, closing a connection that succeeds but after the timeout, and disposing of the TcpClient.
It may be overkill but this works for me.
private class State
{
public TcpClient Client { get; set; }
public bool Success { get; set; }
}
public TcpClient Connect(string hostName, int port, int timeout)
{
var client = new TcpClient();
//when the connection completes before the timeout it will cause a race
//we want EndConnect to always treat the connection as successful if it wins
var state = new State { Client = client, Success = true };
IAsyncResult ar = client.BeginConnect(hostName, port, EndConnect, state);
state.Success = ar.AsyncWaitHandle.WaitOne(timeout, false);
if (!state.Success || !client.Connected)
throw new Exception("Failed to connect.");
return client;
}
void EndConnect(IAsyncResult ar)
{
var state = (State)ar.AsyncState;
TcpClient client = state.Client;
try
{
client.EndConnect(ar);
}
catch { }
if (client.Connected && state.Success)
return;
client.Close();
}
They each addresses different problems and can even be combined together to have something like below

You can get SQL Server Management Studio to do it for you:
This will produce a script to set permissions for all selected objects but suppresses the object scripts themselves.
This is based on the dialog for MS SQL 2008 with all other scripting options unchanged from install defaults.
Function LastRow(rng As Range) As Long
Dim iRowN As Long
Dim iRowI As Long
Dim iColN As Integer
Dim iColI As Integer
iRowN = 0
iColN = rng.Columns.count
For iColI = 1 To iColN
iRowI = rng.Columns(iColI).Offset(65536 - rng.Row, 0).End(xlUp).Row
If iRowI > iRowN Then iRowN = iRowI
Next
LastRow = iRowN
End Function
The following is function would work for async

If your dictionary isn't too big maybe str + eval can do the work:
dict1 = {'one':1, 'two':2, 'three': {'three.1': 3.1, 'three.2': 3.2 }}
str1 = str(dict1)
dict2 = eval(str1)
print dict1==dict2
You can use ast.literal_eval instead of eval for additional security if the source is untrusted.
I don't know much about jQuery, but try this:
row_id = "#5";
row = $("body").find(row_id);
Edit: Of course, if the variable is a number, you have to add "#"
to the front:
row_id = 5
row = $("body").find("#"+row_id);
Just call dict()
on the list of tuples directly
>>> my_list = [('a', 1), ('b', 2)]
>>> dict(my_list)
{'a': 1, 'b': 2}
Use array_shift
function
$myarray = array_shift($myarray);
This will move array elements one level up and you can access any array element without using [0]
key
echo $myarray['email'];
will show [email protected]
The solutions above are right but might crash in FireFox and Safari! and that's what webility.js is trying to solve. Check the toUTC

This is the case from the question because the OP wants to commit to a new branch and also applies if your changes are compatible with the target branch without triggering an overwrite.
As in the accepted answer by John Brodie, you can simply checkout the new branch and commit the work:
git checkout -b branch_name
git add <files>
git commit -m "message"
If you get the error:
error: Your local changes to the following files would be overwritten by checkout:
...
Please commit your changes or stash them before you switch branches
Then you can stash your work, create a new branch, then pop your stash changes, and resolve the conflicts:
git stash
git checkout -b branch_name
git stash pop
It will be as if you had made those changes after creating the new branch. Then you can commit as usual:
git add <files>
git commit -m "message"
See the answer by Carl Norum with cherry-picking, which is the right tool in this case:
git checkout <target name>
git cherry-pick <original branch>
See the answer by joeytwiddle on this potential duplicate. Follow any of the above steps as appropriate, then roll back the original branch:
git branch -f <original branch> <earlier commit id>
If you have pushed your changes to a shared remote like GitHub, you should not attempt this roll-back unless you know what you are doing.
This one works for me
CREATE Function [dbo].[RemoveNumericCharacters](@Temp VarChar(1000))
Returns VarChar(1000)
AS
Begin
Declare @NumRange as varchar(50) = '%[0-9]%'
While PatIndex(@NumRange, @Temp) > 0
Set @Temp = Stuff(@Temp, PatIndex(@NumRange, @Temp), 1, '')
Return @Temp
End
and you can use it like so
SELECT dbo.[RemoveNumericCharacters](Name) FROM TARGET_TABLE
import re
fancy = u'abcde(date=\'2/xc2/xb2\',time=\'/case/test.png\')'
print re.compile( "\((.*)\)" ).search( fancy ).group( 1 )
to set the height of table, you need to first set css property "display: block" then you can add "width/height" properties. I find this Mozilla Article a very good resource to learn how to style tables : Link
I am facing the same problem. I am trying to add a MVC project which was created on Visual Studio 2015 to a solution that I made on Visual Studio 2019.
There are already existing projects on Visual Studio 2019, so adding this existing project which I created on VS 2015 triggers this same error. I've tried all the answers here but it doesn't fixes the problem.
What I did is just put the .nuget folder on the solution folder. Originally the hierarchy of the folder is this:
Solution Folder (VS 2019)
-> MVC 1 Project
-> MVC 2 Project
-> MVC 3 Project (Project that I am adding)
-> .nuget folder (It contains a .nuget folder)
So the issue was fixed when I moved the .nuget folder on the solution folder itself:
Solution Folder (VS 2019)
-> MVC 1 Project
-> MVC 2 Project
-> MVC 3 Project (Project that I am adding)
-> .nuget folder (It contains a .nuget folder)
If it helps, You can also create an alias in your .bashrc
or .bash_profile
.
function dsize()
{
dir=$(pwd)
if [ "$1" != "" ]; then
dir=$1
fi
echo $(du -hs $dir)
}
This prints the size of the current directory or the directory you have passed as an argument.
Assuming ASCII strings:
string1 = 'Hello'
string2 = 'hello'
if string1.lower() == string2.lower():
print("The strings are the same (case insensitive)")
else:
print("The strings are NOT the same (case insensitive)")
I use this:
template <typename T>
bool fromHex(const std::string& hexValue, T& result)
{
std::stringstream ss;
ss << std::hex << hexValue;
ss >> result;
return !ss.fail();
}
You can also use openssl
to accomplish the same thing:
$ openssl pkcs12 -nokeys -info \
-in </path/to/file.pfx> \
-passin pass:<pfx's password>

It depends a bit on what you want:
A) If you want to specify which libraries to link to, you can use find_library to find libs and then use link_directories and target_link_libraries to.
Of course, it is often worth the effort to write a good find_package script, which nicely adds "imported" libraries with add_library( YourLib IMPORTED ) with correct locations, and platform/build specific pre- and suffixes. You can then simply refer to 'YourLib' and use target_link_libraries.
B) If you wish to specify particular linker-flags, e.g. '-mthreads' or '-Wl,--export-all-symbols' with MinGW-GCC, you can use CMAKE_EXE_LINKER_FLAGS. There are also two similar but undocumented flags for modules, shared or static libraries:
CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS
CMAKE_STATIC_LINKER_FLAGS
Get the array of keys, reverse it, then run your loop
var keys = Object.keys( obj ).reverse();
for(var i = 0; i < keys.length; i++){
var key = keys[i];
var value = obj[key];
//do stuff backwards
}
For most controls, you set its height and width to Auto
in the XAML, and it will size to fit its content.
In code, you set the width/height to double.NaN
. For details, see FrameworkElement.Width, particularly the "remarks" section.
They are equivalent. See this code:
mySlice1 := make([]int, 0)
mySlice2 := []int{}
fmt.Println("mySlice1", cap(mySlice1))
fmt.Println("mySlice2", cap(mySlice2))
Output:
mySlice1 0
mySlice2 0
Both slices have 0
capacity which implies both slices have 0
length (cannot be greater than the capacity) which implies both slices have no elements. This means the 2 slices are identical in every aspect.
See similar questions:
What is the point of having nil slice and empty slice in golang?
You can use string formatting:
>>> a=42
>>> b="bar"
>>> "The number is %d and the word is %s" % (a,b)
'The number is 42 and the word is bar'
But this is removed in Python 3, you should use "str.format()":
>>> a=42
>>> b="bar"
>>> "The number is {0} and the word is {1}".format(a,b)
'The number is 42 and the word is bar'

Newer versions of Android Studio include the Device File Explorer which I've found to be a handy GUI method of downloading files from my development Nexus 7.
You Must make sure you have enabled USB Debugging on the device
Interact with the device content in the file explorer window. Right-click on a file or directory to create a new file or directory, save the selected file or directory to your machine, upload, delete, or synchronize. Double-click a file to open it in Android Studio.
Android Studio saves files you open this way in a temporary directory outside of your project. If you make modifications to a file you opened using the Device File Explorer, and would like to save your changes back to the device, you must manually upload the modified version of the file to the device.
I know this one is already too late. But we can fetch root URL by two methods

FIRST, if you want to be able to access man1.py from man1test.py AND manModules.py from man1.py, you need to properly setup your files as packages and modules.
Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module name
A.B
designates a submodule namedB
in a package namedA
....
When importing the package, Python searches through the directories on
sys.path
looking for the package subdirectory.The
__init__.py
files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such asstring
, from unintentionally hiding valid modules that occur later on the module search path.
You need to set it up to something like this:
man
|- __init__.py
|- Mans
|- __init__.py
|- man1.py
|- MansTest
|- __init.__.py
|- SoftLib
|- Soft
|- __init__.py
|- SoftWork
|- __init__.py
|- manModules.py
|- Unittests
|- __init__.py
|- man1test.py
SECOND, for the "ModuleNotFoundError: No module named 'Soft'
" error caused by from ...Mans import man1
in man1test.py, the documented solution to that is to add man1.py to sys.path
since Mans is outside the MansTest package. See The Module Search Path from the Python documentation. But if you don't want to modify sys.path
directly, you can also modify PYTHONPATH
:
sys.path
is initialized from these locations:
- The directory containing the input script (or the current directory when no file is specified).
PYTHONPATH
(a list of directory names, with the same syntax as the shell variablePATH
).- The installation-dependent default.
THIRD, for from ...MansTest.SoftLib import Soft
which you said "was to facilitate the aforementioned import statement in man1.py", that's now how imports work. If you want to import Soft.SoftLib in man1.py, you have to setup man1.py to find Soft.SoftLib and import it there directly.
With that said, here's how I got it to work.
man1.py:
from Soft.SoftWork.manModules import *
# no change to import statement but need to add Soft to PYTHONPATH
def foo():
print("called foo in man1.py")
print("foo call module1 from manModules: " + module1())
man1test.py
# no need for "from ...MansTest.SoftLib import Soft" to facilitate importing..
from ...Mans import man1
man1.foo()
manModules.py
def module1():
return "module1 in manModules"
Terminal output:
$ python3 -m man.MansTest.Unittests.man1test
Traceback (most recent call last):
...
from ...Mans import man1
File "/temp/man/Mans/man1.py", line 2, in <module>
from Soft.SoftWork.manModules import *
ModuleNotFoundError: No module named 'Soft'
$ PYTHONPATH=$PYTHONPATH:/temp/man/MansTest/SoftLib
$ export PYTHONPATH
$ echo $PYTHONPATH
:/temp/man/MansTest/SoftLib
$ python3 -m man.MansTest.Unittests.man1test
called foo in man1.py
foo called module1 from manModules: module1 in manModules
As a suggestion, maybe re-think the purpose of those SoftLib files. Is it some sort of "bridge" between man1.py and man1test.py? The way your files are setup right now, I don't think it's going to work as you expect it to be. Also, it's a bit confusing for the code-under-test (man1.py) to be importing stuff from under the test folder (MansTest).
run this
// you'll see that it prints Object
console.log(typeof document.location);
you want document.location.toString()
or document.location.href
