I agree with @Bloomca. Passing the value needed from the store into the dispatch function as an argument seems simpler than exporting the store. I made an example here:
import React from "react";
import {connect} from "react-redux";
import * as actions from '../actions';
class App extends React.Component {
handleClick(){
const data = this.props.someStateObject.data;
this.props.someDispatchFunction(data);
}
render(){
return (
<div>
<div onClick={ this.handleClick.bind(this)}>Click Me!</div>
</div>
);
}
}
const mapStateToProps = (state) => {
return { someStateObject: state.someStateObject };
};
const mapDispatchToProps = (dispatch) => {
return {
someDispatchFunction:(data) => { dispatch(actions.someDispatchFunction(data))},
};
}
export default connect(mapStateToProps, mapDispatchToProps)(App);
Use Calendar
Calendar.getInstance().get(Calendar.MILLISECOND);
or
Calendar c=Calendar.getInstance();
c.setTime(new Date()); /* whatever*/
//c.setTimeZone(...); if necessary
c.get(Calendar.MILLISECOND);
In practise though I think it will nearly always equal System.currentTimeMillis()%1000; unless someone has leap-milliseconds or some calendar is defined with an epoch not on a second-boundary.
The list()
function [docs] will convert a string into a list of single-character strings.
>>> list('hello')
['h', 'e', 'l', 'l', 'o']
Even without converting them to lists, strings already behave like lists in several ways. For example, you can access individual characters (as single-character strings) using brackets:
>>> s = "hello"
>>> s[1]
'e'
>>> s[4]
'o'
You can also loop over the characters in the string as you can loop over the elements of a list:
>>> for c in 'hello':
... print c + c,
...

Andy's solution does not work for me. Here I found another way:
git checkout `git rev-list -n 1 --before="2009-07-27 13:37" master`
Node.JS is a server-side technology, not a browser technology. Thus, Node-specific calls, like require()
, do not work in the browser.
See browserify or webpack if you wish to serve browser-specific modules from Node.
the solution was simple -
toDoublefunc = UserDefinedFunction(lambda x: float(x),DoubleType())
changedTypedf = joindf.withColumn("label",toDoublefunc(joindf['show']))
exec has memory limitation of buffer size of 512k. In this case it is better to use spawn. With spawn one has access to stdout of executed command at run time
var spawn = require('child_process').spawn;
var prc = spawn('java', ['-jar', '-Xmx512M', '-Dfile.encoding=utf8', 'script/importlistings.jar']);
//noinspection JSUnresolvedFunction
prc.stdout.setEncoding('utf8');
prc.stdout.on('data', function (data) {
var str = data.toString()
var lines = str.split(/(\r?\n)/g);
console.log(lines.join(""));
});
prc.on('close', function (code) {
console.log('process exit code ' + code);
});
To find the point where to add the -lm in Eclipse-IDE is really horrible, so it took me some time.
If someone else also uses Edlipse, here's the way how to add the command:
Project -> Properties -> C/C++ Build -> Settings -> GCC C Linker -> Miscelleaneous -> Linker flags: in this field add the command -lm
decodeURI(window.location.search)
.replace('?', '')
.split('&')
.map(param => param.split('='))
.reduce((values, [ key, value ]) => {
values[ key ] = value
return values
}, {})
EDIT: Per Michael Dillon's answer, SaveAsText does save the commands in a macro without having to go through converting to VBA. I don't know what happened when I tested that, but it didn't produce useful text in the resulting file.
So, I learned something new today!
ORIGINAL POST: To expand the question, I wondered if there was a way to retrieve the contents of a macro from code, and it doesn't appear that there is (at least not in A2003, which is what I'm running).
There are two collections through which you can access stored Macros:
CurrentDB.Containers("Scripts").Documents
CurrentProject.AllMacros
The properties that Intellisense identifies for the two collections are rather different, because the collections are of different types. The first (i.e., traditional, pre-A2000 way) is via a documents collection, and the methods/properties/members of all documents are the same, i.e., not specific to Macros.
Likewise, the All... collections of CurrentProject return collections where the individual items are of type Access Object. The result is that Intellisense gives you methods/properties/members that may not exist for the particular document/object.
So far as I can tell, there is no way to programatically retrieve the contents of a macro.
This would stand to reason, as macros aren't of much use to anyone who would have the capability of writing code to examine them programatically.
But if you just want to evaluate what the macros do, one alternative would be to convert them to VBA, which can be done programmatically thus:
Dim varItem As Variant
Dim strMacroName As String
For Each varItem In CurrentProject.AllMacros
strMacroName = varItem.Name
'Debug.Print strMacroName
DoCmd.SelectObject acMacro, strMacroName, True
DoCmd.RunCommand acCmdConvertMacrosToVisualBasic
Application.SaveAsText acModule, "Converted Macro- " & strMacroName, _
CurrentProject.Path & "\" & "Converted Macro- " & strMacroName & ".txt"
Next varItem
Then you could use the resulting text files for whatever you needed to do.
Note that this has to be run interactively in Access because it uses DoCmd.RunCommand, and you have to click OK for each macro -- tedious for databases with lots of macros, but not too onerous for a normal app, which shouldn't have more than a handful of macros.
The way the operator works is that it gets incremented at the same time, but if it is before a variable, the expression will evaluate with the incremented/decremented variable:
int x = 0; //x is 0
int y = ++x; //x is 1 and y is 1
If it is after the variable the current statement will get executed with the original variable, as if it had not yet been incremented/decremented:
int x = 0; //x is 0
int y = x++; //'y = x' is evaluated with x=0, but x is still incremented. So, x is 1, but y is 0
I agree with dcp in using pre-increment/decrement (++x) unless necessary. Really the only time I use the post-increment/decrement is in while loops or loops of that sort. These loops are the same:
while (x < 5) //evaluates conditional statement
{
//some code
++x; //increments x
}
or
while (x++ < 5) //evaluates conditional statement with x value before increment, and x is incremented
{
//some code
}
You can also do this while indexing arrays and such:
int i = 0;
int[] MyArray = new int[2];
MyArray[i++] = 1234; //sets array at index 0 to '1234' and i is incremented
MyArray[i] = 5678; //sets array at index 1 to '5678'
int temp = MyArray[--i]; //temp is 1234 (becasue of pre-decrement);
Etc, etc...
Just resolved this issue. Its documented here.
I was calling $rootScope.$apply
twice in the same flow. All I did is wrapped the content of the service function with a setTimeout(func, 1)
.
The Win32_Process
class provides access to both 32-bit and 64-bit processes when the script is run from a 64-bit command shell.
If this is not an option for you, you can try using the taskkill
command:
Dim oShell : Set oShell = CreateObject("WScript.Shell")
' Launch notepad '
oShell.Run "notepad"
WScript.Sleep 3000
' Kill notepad '
oShell.Run "taskkill /im notepad.exe", , True
If you are debugging T4 templates, then this happens all the time. My solution (before MS fixes this) would be just to kill this process:
Task Manager --> User --> T4VSHostProcess.exe
This process only comes up when you debug a T4 template, not when you run one.
The benefit of WireShark is that it could possibly show you errors in levels below the HTTP protocol. Fiddler will show you errors in the HTTP protocol.
If you think the problem is somewhere in the HTTP request issued by the browser, or you are just looking for more information in regards to what the server is responding with, or how long it is taking to respond, Fiddler should do.
If you suspect something may be wrong in the TCP/IP protocol used by your browser and the server (or in other layers below that), go with WireShark.

Good luck with your implementation.
There are several ways to create a favicon. The best way for you depends on various factors:
If you want to get the job done well and quickly, you can use a favicon generator. This one creates the pictures and HTML code for all major desktop and mobiles browsers. Full disclosure: I'm the author of this site.
Advantages of such solution: it's quick and all compatibility considerations were already addressed for you.
As you suggest, you can create a favicon.ico
file which contains 16x16 and 32x32 pictures (note that Microsoft recommends 16x16, 32x32 and 48x48).
Then, declare it in your HTML code:
<link rel="shortcut icon" href="/path/to/icons/favicon.ico">
This method will work with all desktop browsers, old and new. But most mobile browsers will ignore the favicon.
About your suggestion of placing the favicon.ico
file in the root and not declaring it: beware, although this technique works on most browsers, it is not 100% reliable. For example Windows Safari cannot find it (granted: this browser is somehow deprecated on Windows, but you get the point). This technique is useful when combined with PNG icons (for modern browsers).
In your question, you do not mention the mobile browsers. Most of them will ignore the favicon.ico
file. Although your site may be dedicated to desktop browsers, chances are that you don't want to ignore mobile browsers altogether.
You can achieve a good compatibility with:
favicon.ico
, see above.Declare them with
<link rel="shortcut icon" href="/path/to/icons/favicon.ico">
<link rel="icon" type="image/png" href="/path/to/icons/favicon-192x192.png" sizes="192x192">
<link rel="apple-touch-icon" sizes="180x180" href="/path/to/icons/apple-touch-icon-180x180.png">
This is not the full story, but it's good enough in most cases.
You can use the Scilca XML Progession package available at GitHub.
XMLIterator xi = new VirtualXML.XMLIterator("<xml />");
XMLReader xr = new XMLReader(xi);
Document d = xr.parseDocument();
As already been said, to exclude from status just use:
git status -uno # must be "-uno" , not "-u no"
If you instead want to permanently ignore currently untracked files you can, from the root of your project, launch:
git status --porcelain | grep '^??' | cut -c4- >> .gitignore
Every subsequent call to git status
will explicitly ignore those files.
UPDATE: the above command has a minor drawback: if you don't have a .gitignore
file yet your gitignore will ignore itself! This happens because the file .gitignore
gets created before the git status --porcelain
is executed. So if you don't have a .gitignore
file yet I recommend using:
echo "$(git status --porcelain | grep '^??' | cut -c4-)" > .gitignore
This creates a subshell which completes before the .gitignore
file is created.
COMMAND EXPLANATION as I'm getting a lot of votes (thank you!) I think I'd better explain the command a bit:
git status --porcelain
is used instead of git status --short
because manual states "Give the output in an easy-to-parse format for scripts. This is similar to the short output, but will remain stable across git versions and regardless of user configuration." So we have both the parseability and stability;grep '^??'
filters only the lines starting with ??
, which, according to the git status manual, correspond to the untracked files;cut -c4-
removes the first 3 characters of every line, which gives us just the relative path to the untracked file;|
symbols are pipes, which pass the output of the previous command to the input of the following command;>>
and >
symbols are redirect operators, which append the output of the previous command to a file or overwrites/creates a new file, respectively.ANOTHER VARIANT for those who prefer using sed
instead of grep
and cut
, here's another way:
git status --porcelain | sed -n -e 's/^?? //p' >> .gitignore
It's easy if you are somewhat constrained.
If you have one thread, you just use uniqueID++; Be sure to store the current uniqueID when you exit.
If you have multiple threads, a common synchronized generateUniqueID method works (Implemented the same as above).
The problem is when you have many CPUs--either in a cluster or some distributed setup like a peer-to-peer game.
In that case, you can generally combine two parts to form a single number. For instance, each process that generates a unique ID can have it's own 2-byte ID number assigned and then combine it with a uniqueID++. Something like:
return (myID << 16) & uniqueID++
It can be tricky distributing the "myID" portion, but there are some ways. You can just grab one out of a centralized database, request a unique ID from a centralized server, ...
If you had a Long instead of an Int, one of the common tricks is to take the device id (UUID) of ETH0, that's guaranteed to be unique to a server--then just add on a serial number.
according to documentation:
10.0.2.2 - Special alias to your host loopback interface (i.e., 127.0.0.1 on your development machine)
check Emulator Networking for more tricks on emulator networking.
You can use DataSourceBuilder
if you are using jdbc
starter. Also, in order to override the default autoconfiguration bean you need to mark your bean as a @Primary
In my case I have properties starting with datasource.postgres
prefix.
E.g
@ConfigurationProperties(prefix = "datasource.postgres")
@Bean
@Primary
public DataSource dataSource() {
return DataSourceBuilder
.create()
.build();
}
If it is not feasible for you, then you can use
@Bean
@Primary
public DataSource dataSource() {
return DataSourceBuilder
.create()
.username("")
.password("")
.url("")
.driverClassName("")
.build();
}

By default, the classes in the csv
module use Windows-style line terminators (\r\n
) rather than Unix-style (\n
). Could this be what’s causing the apparent double line breaks?
If so, you can override it in the DictWriter
constructor:
output = csv.DictWriter(open('file3.csv','w'), delimiter=',', lineterminator='\n', fieldnames=headers)
As android:editable=""
is deprecated,
Setting
android:clickable="false"
android:focusable="false"
android:inputType="none"
android:cursorVisible="false"
will make it "read-only".
However, users will still be able to paste into the field or perform any other long click actions. To disable this, simply override onLongClickListener().
In Kotlin:
myEditText.setOnLongClickListener { true }
suffices.
In the Device File Explorer follow the below path :-

$string = substr($string,0,100);
$string = substr($string,0,strrpos($string," "));

I know that my answer came late but it happens to me today and I solved it with the following approach:
^(([A-Z]+),)+([A-Z]+)$
So the first group (([A-Z]+),)+
will match all the repeated patterns except the final one ([A-Z]+)
that will match the final one. and this will be dynamic no matter how many repeated groups in the string.
import codecs
codecs.getencoder('hex_codec')(b'foo')[0]

The answers given here cover pretty well most scenarios for which core dump is not created. However, in my instance, none of these applied. I'm posting this answer as an addition to the other answers.
If your core file is not being created for whatever reason, I recommend looking at the /var/log/messages. There might be a hint in there to why the core file is not created. In my case there was a line stating the root cause:
Executable '/path/to/executable' doesn't belong to any package
To work around this issue edit /etc/abrt/abrt-action-save-package-data.conf and change ProcessUnpackaged from 'no' to 'yes'.
ProcessUnpackaged = yes
This setting specifies whether to create core for binaries not installed with package manager.
For the case that you wish to revert a recently installed package that made several changes to dependencies (such as tensorflow), you can "roll back" to an earlier installation state via the following method:
conda list --revisions
conda install --revision [revision number]
The first command shows previous installation revisions (with dependencies) and the second reverts to whichever revision number
you specify.
Note that if you wish to (re)install a later revision, you may have to sequentially reinstall all intermediate versions. If you had been at revision 23, reinstalled revision 20 and wish to return, you may have to run each:
conda install --revision 21
conda install --revision 22
conda install --revision 23
Short form:
.zip
is an archive format using, usually, the Deflate compression method. The .gz
gzip format is for single files, also using the Deflate compression method. Often gzip is used in combination with tar to make a compressed archive format, .tar.gz
. The zlib library provides Deflate compression and decompression code for use by zip, gzip, png (which uses the zlib wrapper on deflate data), and many other applications.
Long form:
The ZIP format was developed by Phil Katz as an open format with an open specification, where his implementation, PKZIP, was shareware. It is an archive format that stores files and their directory structure, where each file is individually compressed. The file type is .zip
. The files, as well as the directory structure, can optionally be encrypted.
The ZIP format supports several compression methods:
0 - The file is stored (no compression)
1 - The file is Shrunk
2 - The file is Reduced with compression factor 1
3 - The file is Reduced with compression factor 2
4 - The file is Reduced with compression factor 3
5 - The file is Reduced with compression factor 4
6 - The file is Imploded
7 - Reserved for Tokenizing compression algorithm

Methods 1 to 7 are historical and are not in use. Methods 9 through 98 are relatively recent additions and are in varying, small amounts of use. The only method in truly widespread use in the ZIP format is method 8, Deflate, and to some smaller extent method 0, which is no compression at all. Virtually every .zip
file that you will come across in the wild will use exclusively methods 8 and 0, likely just method 8. (Method 8 also has a means to effectively store the data with no compression and relatively little expansion, and Method 0 cannot be streamed whereas Method 8 can be.)
The ISO/IEC 21320-1:2015 standard for file containers is a restricted zip format, such as used in Java archive files (.jar), Office Open XML files (Microsoft Office .docx, .xlsx, .pptx), Office Document Format files (.odt, .ods, .odp), and EPUB files (.epub). That standard limits the compression methods to 0 and 8, as well as other constraints such as no encryption or signatures.
Around 1990, the Info-ZIP group wrote portable, free, open-source implementations of zip
and unzip
utilities, supporting compression with the Deflate format, and decompression of that and the earlier formats. This greatly expanded the use of the .zip
format.
In the early '90s, the gzip format was developed as a replacement for the Unix compress
utility, derived from the Deflate code in the Info-ZIP utilities. Unix compress
was designed to compress a single file or stream, appending a .Z
to the file name. compress
uses the LZW compression algorithm, which at the time was under patent and its free use was in dispute by the patent holders. Though some specific implementations of Deflate were patented by Phil Katz, the format was not, and so it was possible to write a Deflate implementation that did not infringe on any patents. That implementation has not been so challenged in the last 20+ years. The Unix gzip
utility was intended as a drop-in replacement for compress
, and in fact is able to decompress compress
-compressed data (assuming that you were able to parse that sentence). gzip
appends a .gz
to the file name. gzip
uses the Deflate compressed data format, which compresses quite a bit better than Unix compress
, has very fast decompression, and adds a CRC-32 as an integrity check for the data. The header format also permits the storage of more information than the compress
format allowed, such as the original file name and the file modification time.
Though compress
only compresses a single file, it was common to use the tar
utility to create an archive of files, their attributes, and their directory structure into a single .tar
file, and to then compress it with compress
to make a .tar.Z
file. In fact, the tar
utility had and still has an option to do the compression at the same time, instead of having to pipe the output of tar
to compress
. This all carried forward to the gzip format, and tar
has an option to compress directly to the .tar.gz
format. The tar.gz
format compresses better than the .zip
approach, since the compression of a .tar
can take advantage of redundancy across files, especially many small files. .tar.gz
is the most common archive format in use on Unix due to its very high portability, but there are more effective compression methods in use as well, so you will often see .tar.bz2
and .tar.xz
archives.
Unlike .tar
, .zip
has a central directory at the end, which provides a list of the contents. That and the separate compression provides random access to the individual entries in a .zip
file. A .tar
file would have to be decompressed and scanned from start to end in order to build a directory, which is how a .tar
file is listed.
Shortly after the introduction of gzip, around the mid-1990s, the same patent dispute called into question the free use of the .gif
image format, very widely used on bulletin boards and the World Wide Web (a new thing at the time). So a small group created the PNG losslessly compressed image format, with file type .png
, to replace .gif
. That format also uses the Deflate format for compression, which is applied after filters on the image data expose more of the redundancy. In order to promote widespread usage of the PNG format, two free code libraries were created. libpng and zlib. libpng handled all of the features of the PNG format, and zlib provided the compression and decompression code for use by libpng, as well as for other applications. zlib was adapted from the gzip
code.
All of the mentioned patents have since expired.
The zlib library supports Deflate compression and decompression, and three kinds of wrapping around the deflate streams. Those are: no wrapping at all ("raw" deflate), zlib wrapping, which is used in the PNG format data blocks, and gzip wrapping, to provide gzip routines for the programmer. The main difference between zlib and gzip wrapping is that the zlib wrapping is more compact, six bytes vs. a minimum of 18 bytes for gzip, and the integrity check, Adler-32, runs faster than the CRC-32 that gzip uses. Raw deflate is used by programs that read and write the .zip
format, which is another format that wraps around deflate compressed data.
zlib is now in wide use for data transmission and storage. For example, most HTTP transactions by servers and browsers compress and decompress the data using zlib, specifically HTTP header Content-Encoding: deflate
means deflate compression method wrapped inside the zlib data format.
Different implementations of deflate can result in different compressed output for the same input data, as evidenced by the existence of selectable compression levels that allow trading off compression effectiveness for CPU time. zlib and PKZIP are not the only implementations of deflate compression and decompression. Both the 7-Zip archiving utility and Google's zopfli library have the ability to use much more CPU time than zlib in order to squeeze out the last few bits possible when using the deflate format, reducing compressed sizes by a few percent as compared to zlib's highest compression level. The pigz utility, a parallel implementation of gzip, includes the option to use zlib (compression levels 1-9) or zopfli (compression level 11), and somewhat mitigates the time impact of using zopfli by splitting the compression of large files over multiple processors and cores.
There is a trick for adding margin automatically only for the 2nd+ row in the container.
.container-row-margin .row + .row {
margin-top: 1rem;
}
Adding the .container-row-margin
to the container, results in:
Complete HTML:
<div class="bg-secondary text-white">
div outside of the container.
</div>
<div class="container container-row-margin">
<div class="row">
<div class="col col-4 bg-warning">
Row without top margin
</div>
</div>
<div class="row">
<div class="col col-4 bg-primary text-white">

According to PHPMailer Manual, full answer would be :
$mail->AddEmbeddedImage(filename, cid, name);
//Example
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg ');
Use Case :
$mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
$mail->Body = 'Embedded Image: <img alt="PHPMailer" src="cid:my-attach"> Here is an image!';
If you want to display an image with a remote URL :
$mail->addStringAttachment(file_get_contents("url"), "filename");
Gmap writes inline style position to relative to the div. Overwrite that with :
google.maps.event.addListener(map, 'tilesloaded', function(){
document.getElementById('maps').style.position = 'static';
document.getElementById('maps').style.background = 'none';
});
Hope it helps.
Yep, make Stored proc parameter as VARCHAR(...)
And then pass comma separated values to a stored procedure.
If you are using Sql Server 2008 you can leverage TVP (Table Value Parameters): SQL 2008 TVP and LINQ if structure of QueryTable more complex than array of strings otherwise it would be an overkill because requires table type to be created within SQl Server
You can do as @Hugo of @Laurent said, or you can use git rebase
to delete the commits you want to get rid off, if you know which ones. I tend to use git rebase -i head~N
(where N is a number, allowing you to manipulate the last N commits) for this kind of operations.

Are you ssh'ing to a directory that's inside your work tree? If the root of your ssh mount point doesn't include the .git dir, then zsh won't be able to find git info. Make sure you're mounting something that includes the root of the repo.
As for GIT_DISCOVERY_ACROSS_FILESYSTEM, it doesn't do what you want. Git by default will stop at a filesystem boundary. If you turn that on (and it's just an env var), then git will cross the filesystem boundary and keep looking. However, that's almost never useful, because you'd be implying that you have a .git directory on your local machine that's somehow meant to manage a work tree that's comprised partially of an sshfs mount. That doesn't make much sense.
git fetch && git merge origin/develop
I faced the same issues. To solve this, I used export PYTHONPATH="$PWD"
. However, in this case, you will need to modify imports in your Scripts
dir depending on the below:
Case 1: If you are in the user_management
dir, your scripts
should use this style from Modules import LDAPManager
to import module.
Case 2: If you are out of the user_management
1 level like main
, your scripts
should use this style from user_management.Modules import LDAPManager
to import modules.
For ansible, and using hyphen, this worked for me:

If you want to search for these invisible characters in your editor and make them visible, you can use a Regular Expression searching for non-ascii characters.
Try searching for [^\x00-\x7F]
.

If you want to convert an int which is in the range 0-9 to a char, you may usually write something like this:
int x;
char c = '0' + x;
Now, if you want a character string, just add a terminating '\0' char:
char s[] = {'0' + x, '\0'};
Note that:
Using Quick Watch in Visual Studio you can access the LoaderExceptions from ViewDetails of the thrown exception like this:

Let's assume we have an array of objects and you want to check if value of name is defined like this,
let persons = [ {"name" : "test1"},{"name": "test2"}];
if(persons.some(person => person.name == 'test1')) {
... here your code in case person.name is defined and available
}
It is possible to implement custom bootstrap checkbox for the most popular browsers nowadays.
You can check my Bootstrap-Checkbox project in GitHub, which contains simple .less file. There is a good article in MDN describing some techniques, where the two major are:
Label redirects a click event.
Label can redirect a click event to its target if it has the for
attribute like in <label for="target_id">Text</label> <input id="target_id" type="checkbox" />
, or if it contains input as in Bootstrap case: <label><input type="checkbox" />Text</label>
.
It means that it is possible to place a label in one corner of the browser, click on it, and then the label will redirect click event to the checkbox located in other corner producing check/uncheck action for the checkbox.
We can hide original checkbox visually, but make it is still working and taking click event from the label. In the label itself we can emulate checkbox with a tag or pseudo-element :before :after
.
General non supported tag for old browsers
Some old browsers does not support several CSS features like selecting siblings p+p
or specific search input[type=checkbox]
. According to the MDN article browsers that support these features also support :root
CSS selector, while others not. The :root
selector just selects the root element of a document, which is html
in a HTML page. Thus it is possible to use :root
for a fallback to old browsers and original checkboxes.

While the EGit plugin for Eclipse is a good option, an even better one would be to learn to use git bash -- i.e., git from the command line. It isn't terribly difficult to learn the very basics of git, and it is often very beneficial to understand some basic operations before relying on a GUI to do it for you. But to answer your question:
First things first, download git from http://git-scm.com/. Then go to http://github.com/ and create an account and repository.
On your machine, first you will need to navigate to the project folder using git bash. When you get there you do:
git init
which initiates a new git repository in that directory.
When you've done that, you need to register that new repo with a remote (where you'll upload -- push -- your files to), which in this case will be github. This assumes you have already created a github repository. You'll get the correct URL from your repo in GitHub.
git remote add origin https://github.com/[username]/[reponame].git
You need to add you existing files to your local commit:
git add . # this adds all the files
Then you need to make an initial commit, so you do:
git commit -a -m "Initial commit" # this stages your files locally for commit.
# they haven't actually been pushed yet
Now you've created a commit in your local repo, but not in the remote one. To put it on the remote, you do the second line you posted:
git push -u origin --all
List<KeyValuePair<string, string>> kvpList = new List<KeyValuePair<string, string>>()
{
new KeyValuePair<string, string>("Key1", "Value1"),
new KeyValuePair<string, string>("Key2", "Value2"),
new KeyValuePair<string, string>("Key3", "Value3"),
};
kvpList.Insert(0, new KeyValuePair<string, string>("New Key 1", "New Value 1"));
Using this code:
foreach (KeyValuePair<string, string> kvp in kvpList)
{
Console.WriteLine(string.Format("Key: {0} Value: {1}", kvp.Key, kvp.Value);
}
the expected output should be:
Key: New Key 1 Value: New Value 1
Key: Key 1 Value: Value 1
Key: Key 2 Value: Value 2
Key: Key 3 Value: Value 3
The same will work with a KeyValuePair or whatever other type you want to use..
Edit -
To lookup by the key, you can do the following:
var result = stringList.Where(s => s == "Lookup");
You could do this with a KeyValuePair by doing the following:
var result = kvpList.Where (kvp => kvp.Value == "Lookup");
Last edit -
Made the answer specific to KeyValuePair rather than string.
From another answer:
A little history
Remember, there is nothing inherently special about $
. It is a variable name just like any other. In earlier days, people used to write code using document.getElementById. Because JavaScript is case-sensitive, it was normal to make a mistake while writing document.getElementById
. Should I capital 'b'
of 'by'
? Should I capital 'i'
of Id?
You get the drift. Because functions are first-class citizens in JavaScript, you can always do this:
var $ = document.getElementById; //freedom from document.getElementById!
When Prototype library arrived, they named their function, which gets the DOM elements, as '$'
. Almost all the JavaScript libraries copied this idea. Prototype also introduced a $$
function to select elements using CSS selector.
jQuery also adapted $
function but expanded to make it accept all kinds of 'selectors' to get the elements you want. Now, if you are already using Prototype in your project and wanted to include jQuery, you will be in problem as '$'
could either refer to Prototype's implementation OR jQuery's implementation. That's why jQuery has the option of noConflict so that you can include jQuery in your project which uses Prototype and slowly migrate your code. I think this was a brilliant move on John's part! :)
Nice question, a while ago I've experimented a bit with this, but haven't used it a lot because it's still not bulletproof. I divided the plot area into a 32x32 grid and calculated a 'potential field' for the best position of a label for each line according the following rules:
The code was something like this:
import matplotlib.pyplot as plt
import numpy as np
from scipy import ndimage
def my_legend(axis = None):
if axis == None:
axis = plt.gca()
N = 32
Nlines = len(axis.lines)
print Nlines
xmin, xmax = axis.get_xlim()
ymin, ymax = axis.get_ylim()
# the 'point of presence' matrix
pop = np.zeros((Nlines, N, N), dtype=np.float)
for l in range(Nlines):
# get xy data and scale it to the NxN squares
xy = axis.lines[l].get_xydata()
xy = (xy - [xmin,ymin]) / ([xmax-xmin, ymax-ymin]) * N
xy = xy.astype(np.int32)
# mask stuff outside plot
mask = (xy[:,0] >= 0) & (xy[:,0] < N) & (xy[:,1] >= 0) & (xy[:,1] < N)
xy = xy[mask]
# add to pop
for p in xy:
pop[l][tuple(p)] = 1.0
# find whitespace, nice place for labels
ws = 1.0 - (np.sum(pop, axis=0) > 0) * 1.0
# don't use the borders
ws[:,0] = 0
ws[:,N-1] = 0
ws[0,:] = 0
ws[N-1,:] = 0
# blur the pop's
for l in range(Nlines):
pop[l] = ndimage.gaussian_filter(pop[l], sigma=N/5)
for l in range(Nlines):
# positive weights for current line, negative weight for others....
w = -0.3 * np.ones(Nlines, dtype=np.float)
w[l] = 0.5
# calculate a field
p = ws + np.sum(w[:, np.newaxis, np.newaxis] * pop, axis=0)
plt.figure()
plt.imshow(p, interpolation='nearest')
plt.title(axis.lines[l].get_label())
pos = np.argmax(p) # note, argmax flattens the array first
best_x, best_y = (pos / N, pos % N)
x = xmin + (xmax-xmin) * best_x / N
y = ymin + (ymax-ymin) * best_y / N
axis.text(x, y, axis.lines[l].get_label(),
horizontalalignment='center',
verticalalignment='center')
plt.close('all')
x = np.linspace(0, 1, 101)
y1 = np.sin(x * np.pi / 2)
y2 = np.cos(x * np.pi / 2)
y3 = x * x
plt.plot(x, y1, 'b', label='blue')
plt.plot(x, y2, 'r', label='red')
plt.plot(x, y3, 'g', label='green')
my_legend()
plt.show()
And the resulting plot:
Android Studio debug.keystore file path depend on environment variable ANDROID_SDK_HOME.
If ANDROID_SDK_HOME defined, then file placed in SDK's subfolder named .android .
When not defined, then keystore placed at user home path in same subfolder:
- %HOMEPATH%\.android\ on Windows
- $HOME/.android/ on Linux
Try this. It worked for me:
- (void) viewDidLoad
{
[super viewDidLoad];
// Without ARC
//self.tableView.tableFooterView = [[[UIView alloc] init] autorelease];
// With ARC, tried on Xcode 5
self.tableView.tableFooterView = [UIView new];
}

The code you posted tries to save an array of custom objects to NSUserDefaults
. You can't do that. Implementing the NSCoding
methods doesn't help. You can only store things like NSArray
, NSDictionary
, NSString
, NSData
, NSNumber
, and NSDate
in NSUserDefaults
.
You need to convert the object to NSData
(like you have in some of the code) and store that NSData
in NSUserDefaults
. You can even store an NSArray
of NSData
if you need to.
When you read back the array you need to unarchive the NSData
to get back your BC_Person
objects.
Perhaps you want this:
- (void)savePersonArrayData:(BC_Person *)personObject {
[mutableDataArray addObject:personObject];
NSMutableArray *archiveArray = [NSMutableArray arrayWithCapacity:mutableDataArray.count];
for (BC_Person *personObject in mutableDataArray) {
NSData *personEncodedObject = [NSKeyedArchiver archivedDataWithRootObject:personObject];
[archiveArray addObject:personEncodedObject];
}
NSUserDefaults *userData = [NSUserDefaults standardUserDefaults];
[userData setObject:archiveArray forKey:@"personDataArray"];
}
For large dataframes of numeric data, you may see a significant performance improvement via numpy.lexsort
, which performs an indirect sort using a sequence of keys:
import pandas as pd
import numpy as np
np.random.seed(0)
df1 = pd.DataFrame(np.random.randint(1, 5, (10,2)), columns=['a','b'])
df1 = pd.concat([df1]*100000)
def pdsort(df1):
return df1.sort_values(['a', 'b'], ascending=[True, False])
def lex(df1):
arr = df1.values
return pd.DataFrame(arr[np.lexsort((-arr[:, 1], arr[:, 0]))])
assert (pdsort(df1).values == lex(df1).values).all()
%timeit pdsort(df1) # 193 ms per loop
%timeit lex(df1) # 143 ms per loop
One peculiarity is that the defined sorting order with numpy.lexsort
is reversed: (-'b', 'a')
sorts by series a
first. We negate series b
to reflect we want this series in descending order.
Be aware that np.lexsort
only sorts with numeric values, while pd.DataFrame.sort_values
works with either string or numeric values. Using np.lexsort
with strings will give: TypeError: bad operand type for unary -: 'str'
.
Overview
Some people have multiple Anaconda environments with different versions of python for compatibility reasons. In this case, you should have a script that sets your default environment. With this method, you can preserve the versions of python you use in your environments.
The following assumes environment_name is the name of your environment
Mac / Linux:
Edit your bash profile so that the last line is source activate environment_name
. In Mac OSX this is ~/.bash_profile, in other environments this may be ~/.bashrc
Example:
Here's how i did it on Mac OSX
Open Terminal and type:
nano ~/.bash_profile
Go to end of file and type the following, where "p3.5" is my environment:
source activate p3.5
Exit File. Start a new terminal window.
Type the following to see what environment is active
conda info -e
The result shows that I'm using my p3.5 environment by default.
For Windows:
Create a command file (.cmd) with activate environment_name
and follow these instructions to have it execute whenever you open a command prompt
cmd
. This setting is in Registry:from this answer: https://superuser.com/a/302553/143794
I had the same issue and none of the above solutions worked for me.
Apache uses both ports 80 and 443 (for HTTPS) and both must be ready to be used for Apache to start successfully. Only port 80 might not be enough.
I found in my case that when running VMWare Workstation I had the port 443 used by the VMware sharing.
You have to disable sharing in the VMware main Preferences or change the port in this section.
After that as long as you have no other server hooked to the port 80 (see above solutions) then you should be able to start Apache or NGinx on XAMPP or any other Windows stack application.
I hope this will help other users.

The Cocotron is an open source project which aims to implement a cross-platform Objective-C API similar to that described by Apple Inc.'s Cocoa documentation. This includes the AppKit, Foundation, Objective-C runtime and support APIs such as CoreGraphics and CoreFoundation.
@Html.DropDownListFor(m => m.SelectedValue,Your List,"ID","Values")
Here Value is that object of model where you want to save your Selected Value
@RequestParam annotation used for accessing the query parameter values from the request. Look at the following request URL:
http://localhost:8080/springmvc/hello/101?param1=10¶m2=20
In the above URL request, the values for param1 and param2 can be accessed as below:
public String getDetails(
@RequestParam(value="param1", required=true) String param1,
@RequestParam(value="param2", required=false) String param2){
...
}
The following are the list of parameters supported by the @RequestParam annotation:
@PathVariable
@PathVariable identifies the pattern that is used in the URI for the incoming request. Let’s look at the below request URL:
http://localhost:8080/springmvc/hello/101?param1=10¶m2=20
The above URL request can be written in your Spring MVC as below:
@RequestMapping("/hello/{id}") public String getDetails(@PathVariable(value="id") String id,
@RequestParam(value="param1", required=true) String param1,
@RequestParam(value="param2", required=false) String param2){
.......
}
The @PathVariable annotation has only one attribute value for binding the request URI template. It is allowed to use the multiple @PathVariable annotation in the single method. But, ensure that no more than one method has the same pattern.
Also there is one more interesting annotation: @MatrixVariable
And the Controller method for it
@RequestMapping(value = "/{stocks}", method = RequestMethod.GET)
public String showPortfolioValues(@MatrixVariable Map<String, List<String>> matrixVars, Model model) {
logger.info("Storing {} Values which are: {}", new Object[] { matrixVars.size(), matrixVars });
List<List<String>> outlist = map2List(matrixVars);
model.addAttribute("stocks", outlist);
return "stocks";
}
But you must enable:
<mvc:annotation-driven enableMatrixVariables="true" >
this.HttpContext.Response.StatusCode = 418; // I'm a teapot
How to end the request?
Try other solution, just:
return StatusCode(418);
You could use StatusCode(???)
to return any HTTP status code.
Also, you can use dedicated results:
Success:
return Ok()
? Http status code 200return Created()
? Http status code 201return NoContent();
? Http status code 204Client Error:
return BadRequest();
? Http status code 400return Unauthorized();
? Http status code 401return NotFound();
? Http status code 404

UTF-8 without BOM has no BOM, which doesn't make it any better than UTF-8 with BOM, except when the consumer of the file needs to know (or would benefit from knowing) whether the file is UTF-8-encoded or not.
The BOM is usually useful to determine the endianness of the encoding, which is not required for most use cases.
Also, the BOM can be unnecessary noise/pain for those consumers that don't know or care about it, and can result in user confusion.
--force-reinstall

What i did was i commented out the
props.put("mail.smtp.starttls.enable","true");
Because apparently for G-mail you did not need it. Then if you haven't already done this you need to create an app password in G-mail for your program. I did that and it worked perfectly. Here this link will show you how: https://support.google.com/accounts/answer/185833.
You can completely avoid manually doing the transforms and scaling yourself, as suggested by an0 in this answer here:
- (UIImage *)normalizedImage {
if (self.imageOrientation == UIImageOrientationUp) return self;
UIGraphicsBeginImageContextWithOptions(self.size, NO, self.scale);
[self drawInRect:(CGRect){0, 0, self.size}];
UIImage *normalizedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return normalizedImage;
}
The documentation for the UIImage methods size and drawInRect explicitly states that they take into account orientation.
If you make your parent element be "position: relative", then it will be the "offset parent" for the stuff you're tracking mouse events over. Thus the jQuery "position()" will be relative to that.
I use Xcode 7 and Swift 2. Last, I had made:
class ViewController: UIViewController{ var time: NSTimer //error this here }
Then I fix: class ViewController: UIViewController {
var time: NSTimer!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func viewWillAppear(animated: Bool) {
//self.movetoHome()
time = NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: #selector(ViewController.movetoHome), userInfo: nil, repeats: false)
//performSegueWithIdentifier("MoveToHome", sender: self)
//presentViewController(<#T##viewControllerToPresent: UIViewController##UIViewController#>, animated: <#T##Bool#>, completion: <#T##(() -> Void)?##(() -> Void)?##() -> Void#>)
}
func movetoHome(){
performSegueWithIdentifier("MoveToHome", sender: self)
}
}
To write to a file:
import json
myfile.write(json.dumps(mydict))
To read from a file:
import json
mydict = json.loads(myfile.read())
myfile
is the file object for the file that you stored the dict in.
In some devices void onConfigurationChanged()
may crash. User will use this code to get current screen orientation.
public int getScreenOrientation()
{
Display getOrient = getActivity().getWindowManager().getDefaultDisplay();
int orientation = Configuration.ORIENTATION_UNDEFINED;
if(getOrient.getWidth()==getOrient.getHeight()){
orientation = Configuration.ORIENTATION_SQUARE;
} else{
if(getOrient.getWidth() < getOrient.getHeight()){
orientation = Configuration.ORIENTATION_PORTRAIT;
}else {
orientation = Configuration.ORIENTATION_LANDSCAPE;
}
}
return orientation;
}
And use
if (orientation==1) // 1 for Configuration.ORIENTATION_PORTRAIT
{ // 2 for Configuration.ORIENTATION_LANDSCAPE
//your code // 0 for Configuration.ORIENTATION_SQUARE
}
I just want to build upon Serpens answer and add the line:
logger.setLevel('DEBUG')
This will allow you to chose what level of message gets logged.
For example in Serpens example,
logger.info('Info message')
Will not get recorded as it defaults to only recording Warnings and above.
More about levels used can be read about here
To use unsafe code blocks, the project has to be compiled with the /unsafe switch on.

It is easy for tools and humans to differentiate something. That's it.
In conventional use (by boost, etc), .hpp
is specifically C++ headers. On the other hand, .h
is for non-C++-only headers (mainly C). To precisely detect the language of the content is generally hard since there are many non-trivial cases, so this difference often makes a ready-to-use tool easy to write. For humans, once get the convention, it is also easy to remember and easy to use.
However, I'd point out the convention itself does not always work, as expected.
.hpp
itself is not the only choice. Why not .hh
or .hxx
? (Though anyway, you usually need at least one conventional rule about filenames and paths.)I personally use both .h
and .hpp
in my C++ projects. I don't follow the convention above because:
.h
files on github.com. (There may be something in comments like shebang for these source files to be better metadata, but it is even not conventional like filenames, so also not reliable in general.)I usually use .hpp
on C++ headers and the headers should be used (maintained) in a header-only manner, e.g. as template libraries. For other headers in .h
, either there is a corresponding .cpp
file as implementation, or it is a non-C++ header. The latter is trivial to differentiate through the contents of the header by humans (or by tools with explicit embedded metadata, if needed).
I don't know jQuery, but I do know that if you get the select element, it contains an 'options' object.
var myOpts = document.getElementById('yourselect').options;
alert(myOpts[0].value) //=> Value of the first option

/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/jsp-api-6.0.16.jar
/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/servlet-api-6.0.16.jar
You should not have any server-specific libraries in the /WEB-INF/lib
. Leave them in the appserver's own library. It would only lead to collisions in the classpath. Get rid of all appserver-specific libraries in /WEB-INF/lib
(and also in JRE/lib
and JRE/lib/ext
if you have placed any of them there).
A common cause that the appserver-specific libraries are included in the webapp's library is that starters think that it is the right way to fix compilation errors of among others the javax.servlet
classes not being resolveable. Putting them in webapp's library is the wrong solution. You should reference them in the classpath during compilation, i.e. javac -cp /path/to/server/lib/servlet.jar
and so on, or if you're using an IDE, you should integrate the server in the IDE and associate the web project with the server. The IDE will then automatically take server-specific libraries in the classpath (buildpath) of the webapp project.
I advocate an object oriented approach. This is the template that I start out with:
# Use Tkinter for python 2, tkinter for python 3
import tkinter as tk
class MainApplication(tk.Frame):
def __init__(self, parent, *args, **kwargs):
tk.Frame.__init__(self, parent, *args, **kwargs)
self.parent = parent
<create the rest of your GUI here>
if __name__ == "__main__":
root = tk.Tk()
MainApplication(root).pack(side="top", fill="both", expand=True)
root.mainloop()
The important things to notice are:
I don't use a wildcard import. I import the package as "tk", which requires that I prefix all commands with tk.
. This prevents global namespace pollution, plus it makes the code completely obvious when you are using Tkinter classes, ttk classes, or some of your own.
The main application is a class. This gives you a private namespace for all of your callbacks and private functions, and just generally makes it easier to organize your code. In a procedural style you have to code top-down, defining functions before using them, etc. With this method you don't since you don't actually create the main window until the very last step. I prefer inheriting from tk.Frame
just because I typically start by creating a frame, but it is by no means necessary.
If your app has additional toplevel windows, I recommend making each of those a separate class, inheriting from tk.Toplevel
. This gives you all of the same advantages mentioned above -- the windows are atomic, they have their own namespace, and the code is well organized. Plus, it makes it easy to put each into its own module once the code starts to get large.
Finally, you might want to consider using classes for every major portion of your interface. For example, if you're creating an app with a toolbar, a navigation pane, a statusbar, and a main area, you could make each one of those classes. This makes your main code quite small and easy to understand:
class Navbar(tk.Frame): ...
class Toolbar(tk.Frame): ...
class Statusbar(tk.Frame): ...
class Main(tk.Frame): ...
class MainApplication(tk.Frame):
def __init__(self, parent, *args, **kwargs):
tk.Frame.__init__(self, parent, *args, **kwargs)
self.statusbar = Statusbar(self, ...)
self.toolbar = Toolbar(self, ...)
self.navbar = Navbar(self, ...)
self.main = Main(self, ...)
self.statusbar.pack(side="bottom", fill="x")
self.toolbar.pack(side="top", fill="x")
self.navbar.pack(side="left", fill="y")
self.main.pack(side="right", fill="both", expand=True)
Since all of those instances share a common parent, the parent effectively becomes the "controller" part of a model-view-controller architecture. So, for example, the main window could place something on the statusbar by calling self.parent.statusbar.set("Hello, world")
. This allows you to define a simple interface between the components, helping to keep coupling to a minimun.
My solution:
String.prototype.toCapital = function () {
return this.toLowerCase().split(' ').map(function (i) {
if (i.length > 2) {
return i.charAt(0).toUpperCase() + i.substr(1);
}
return i;
}).join(' ');
};
Example:
'álL riGht'.toCapital();
// Returns 'Áll Right'
If your program has an upper bound to n
(say n <= N
) and needs to repeatedly compute nCr (preferably for >>N
times), using lru_cache can give you a huge performance boost:
from functools import lru_cache
@lru_cache(maxsize=None)
def nCr(n, r):
return 1 if r == 0 or r == n else nCr(n - 1, r - 1) + nCr(n - 1, r)
Constructing the cache (which is done implicitly) takes up to O(N^2)
time. Any subsequent calls to nCr
will return in O(1)
.
The printStackTrace()
helps the programmer understand where the actual problem occurred. The printStackTrace()
method is a member of the class Throwable
in the java.lang
package.
A single-quoted string does not have variables within it interpreted. A double-quoted string does.
Also, a double-quoted string can contain apostrophes without backslashes, while a single-quoted string can contain unescaped quotation marks.
The single-quoted strings are faster at runtime because they do not need to be parsed.
Core Java is Sun Microsystem's, used to refer to Java SE. And there are Java ME and Java EE (J2EE). So this is told in order to differentiate with the Java ME and J2EE. So I feel Core Java is only used to mention J2SE.
Java having 3 category:
J2SE(Java to Standard Edition) - Core Java
J2EE(Java to Enterprises Edition)- Advance Java + Framework
J2ME(Java to Micro Edition)

If you are working in asp.net with razor, and you want to control multiple submit button event.then this answer will guide you. Lets for example we have two button, one button will redirect us to "PageA.cshtml" and other will redirect us to "PageB.cshtml".
@{
if (IsPost)
{
if(Request["btn"].Equals("button_A"))
{
Response.Redirect("PageA.cshtml");
}
if(Request["btn"].Equals("button_B"))
{
Response.Redirect("PageB.cshtml");
}
}
}
<form method="post">
<input type="submit" value="button_A" name="btn"/>;
<input type="submit" value="button_B" name="btn"/>;

In GitHub Desktop you can just right click the commit and revert it, which will create a new commit that undoes the changes.
The accidental commit will still be in your history (which may be an issue if, for instance, you've accidentally commited an API key or password) but the code will be reverted.
This is the simplest and easiest option, the accepted answer is more comprehensive.
You could try JarSpy. There is an IDEA plugin version of it that I use.
Depending on which OS you're using, if you are flexible, then CHOICE
can be used to wait on almost any key EXCEPT
enter
If you are really referring to what Microsoft insists on calling "Command Prompt" which is simply an MS-DOS emulator, then perhaps TIMEOUT
may suit your purpose (timeout /t -1
waits on any key, not just ENTER
) and of course CHOICE
is available again in recent WIN editions.
And a warning on SET /P
- whereas set /p DUMMY=Hit ENTER to continue...
will work,
set "dummy="
set /p DUMMY=Hit ENTER to continue...
if defined dummy (echo not just ENTER was pressed) else (echo just ENTER was pressed)
will detect whether just ENTER or something else, ending in ENTER was keyed in.
I had the same issue inside an alpine docker container, my solution was to add the boost-dev apk library because libboost-dev was not available.
Here's another:
data[data$Code == "A" | data$Code == "B", ]
It's also worth mentioning that the subsetting factor doesn't have to be part of the data frame if it matches the data frame rows in length and order. In this case we made our data frame from this factor anyway. So,
data[Code == "A" | Code == "B", ]
also works, which is one of the really useful things about R.
Using LINQ is relatively much slower than using a predicate supplied to the Lists FindAll
method. Also be careful with LINQ as the enumeration of the list
is not actually executed until you access the result. This can mean that, when you think you have created a filtered list, the content may differ to what you expected when you actually read it.
You should be able to transfer the Application to another Username. You would need all your old user information to transfer it. The application would remove it's self from old account to new account. Also you could put a limit on how many times you where allowed to transfer it. If you transfer it to the application could expire after a year and force to buy update.
Simply use JS toLowerCase()
let v = "Your Name"
let u = v.toLowerCase();

In a nutshell answer.
Incredibly late but inspired by Homan's brilliantly simple answer, allow me to post a more general solution (general in the sense that Homan's solution crashes on arrays of points with less than 3 vertices):
function smooth(ctx, points)
{
if(points == undefined || points.length == 0)
{
return true;
}
if(points.length == 1)
{
ctx.moveTo(points[0].x, points[0].y);
ctx.lineTo(points[0].x, points[0].y);
return true;
}
if(points.length == 2)
{
ctx.moveTo(points[0].x, points[0].y);
ctx.lineTo(points[1].x, points[1].y);
return true;
}
ctx.moveTo(points[0].x, points[0].y);
for (var i = 1; i < points.length - 2; i ++)
{
var xc = (points[i].x + points[i + 1].x) / 2;
var yc = (points[i].y + points[i + 1].y) / 2;
ctx.quadraticCurveTo(points[i].x, points[i].y, xc, yc);
}
ctx.quadraticCurveTo(points[i].x, points[i].y, points[i+1].x, points[i+1].y);
}
First give the link of logout.php
page in that logout button.In that page make the code which is given below:
Here is the code:
<?php
session_start();
session_destroy();
?>
When the session has started, the session for the last/current user has been started, so don't need to declare the username. It will be deleted automatically by the session_destroy method.
Hold down the Alt key and drag the pictures to snap to the upper left corner of the cell.
Format the picture and in the Properties tab select "Move but don't size with cells"
Now you can sort the data table by any column and the pictures will stay with the respective data.

If you define the ListView
in XAML:
<ListView x:Name="listView"/>
Then you can add columns and populate it in C#:
public Window()
{
// Initialize
this.InitializeComponent();
// Add columns
var gridView = new GridView();
this.listView.View = gridView;
gridView.Columns.Add(new GridViewColumn {
Header = "Id", DisplayMemberBinding = new Binding("Id") });
gridView.Columns.Add(new GridViewColumn {
Header = "Name", DisplayMemberBinding = new Binding("Name") });
// Populate list
this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}
See definition of MyItem
below.
However, it's easier to define the columns in XAML (inside the ListView
definition):
<ListView x:Name="listView">
<ListView.View>
<GridView>
<GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
</GridView>
</ListView.View>
</ListView>
And then just populate the list in C#:
public Window()
{
// Initialize
this.InitializeComponent();
// Populate list
this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}
See definition of MyItem
below.
MyItem
DefinitionMyItem
is defined like this:
public class MyItem
{
public int Id { get; set; }
public string Name { get; set; }
}
By default, when you are inside a function, you do not have access to the outer variables.
If you want your function to have access to an outer variable, you have to declare it as global
, inside the function :
function someFuntion(){
global $myArr;
$myVal = //some processing here to determine value of $myVal
$myArr[] = $myVal;
}
For more informations, see Variable scope.
But note that using global variables is not a good practice : with this, your function is not independant anymore.
A better idea would be to make your function return the result :
function someFuntion(){
$myArr = array(); // At first, you have an empty array
$myVal = //some processing here to determine value of $myVal
$myArr[] = $myVal; // Put that $myVal into the array
return $myArr;
}
And call the function like this :
$result = someFunction();
Your function could also take parameters, and even work on a parameter passed by reference :
function someFuntion(array & $myArr){
$myVal = //some processing here to determine value of $myVal
$myArr[] = $myVal; // Put that $myVal into the array
}
Then, call the function like this :
$myArr = array( ... );
someFunction($myArr); // The function will receive $myArr, and modify it
With this :
For more informations about that, you should read the Functions section of the PHP manual, and,, especially, the following sub-sections :
insert into bookmarks (users_id, lessoninfo_id)
select 1, 167
EXCEPT
select user_id, lessoninfo_id
from bookmarks
where user_id=1
and lessoninfo_id=167;
This is the fastest way.
For some other SQL engines, you can use a Dummy table containing 1 record. e.g:
select 1, 167 from ONE_RECORD_DUMMY_TABLE
The tabularx
package gives you

\hline
Input & Output& Action return \\
\hline
\hline
DNF & simulation & jsp\\
\hline
\end{tabularx}

Just discovered that if the source table for a subform is updated using adodb, it takes a while until the requery can find the updated information.
In my case, I was adding some records with 'dbconn.execute "sql" ' and wondered why the requery command in vba doesn't seem to work. When I was debugging, the requery worked. Added a 2-3 second wait in the code before requery just to test made a difference.
But changing to 'currentdb.execute "sql" ' fixed the problem immediately.
As Yaron mentioned, there isn't any difference between where
and filter
.
filter
is an overloaded method that takes a column or string argument. The performance is the same, regardless of the syntax you use.
We can use explain()
to see that all the different filtering syntaxes generate the same Physical Plan. Suppose you have a dataset with person_name
and person_country
columns. All of the following code snippets will return the same Physical Plan below:
df.where("person_country = 'Cuba'").explain()
df.where($"person_country" === "Cuba").explain()
df.where('person_country === "Cuba").explain()
df.filter("person_country = 'Cuba'").explain()
These all return this Physical Plan:
== Physical Plan ==
*(1) Project [person_name#152, person_country#153]
+- *(1) Filter (isnotnull(person_country#153) && (person_country#153 = Cuba))
+- *(1) FileScan csv [person_name#152,person_country#153] Batched: false, Format: CSV, Location: InMemoryFileIndex[file:/Users/matthewpowers/Documents/code/my_apps/mungingdata/spark2/src/test/re..., PartitionFilters: [], PushedFilters: [IsNotNull(person_country), EqualTo(person_country,Cuba)], ReadSchema: struct<person_name:string,person_country:string>
The syntax doesn't change how filters are executed under the hood, but the file format / database that a query is executed on does. Spark will execute the same query differently on Postgres (predicate pushdown filtering is supported), Parquet (column pruning), and CSV files. See here for more details.
This helped me at the end:
Quick guide:
Download Google USB Driver
Connect your device with Android Debugging enabled to your PC
Open Device Manager of Windows from System Properties.
Your device should appear under Other devices
listed as something like
Android ADB Interface
or 'Android Phone' or similar. Right-click that and
click on Update Driver Software...
Select Browse my computer for driver software
Select Let me pick from a list of device drivers on my computer
Double-click Show all devices
Press the Have disk
button
Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf
Select Android ADB Interface
from the list of device types.
Press the Yes
button
Press the Install
button
Press the Close
button
Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.
You can use the extension methods below as well and do like this
int? id = Request["id"].ToInt();
if(id.HasValue)
{
}
// Extension methods
public static int? ToInt(this string input)
{
int val;
if (int.TryParse(input, out val))
return val;
return null;
}
public static DateTime? ToDate(this string input)
{
DateTime val;
if (DateTime.TryParse(input, out val))
return val;
return null;
}
public static decimal? ToDecimal(this string input)
{
decimal val;
if (decimal.TryParse(input, out val))
return val;
return null;
}
All is explained quite nicely on gruntjs.com.
Note that installing grunt-cli does not install the grunt task runner! The job of the grunt CLI is simple: run the version of grunt which has been installed next to a Gruntfile. This allows multiple versions of grunt to be installed on the same machine simultaneously.
So in your project folder, you will need to install (preferably) the latest grunt version:
npm install grunt --save-dev
Option --save-dev
will add grunt
as a dev-dependency to your package.json. This makes it easy to reinstall dependencies.
The command you are seeking is comm
. eg:-
comm -12 1.sorted.txt 2.sorted.txt
Here:

you can use LINQ
string abc = "abc";
char getresult = abc.Where((item, index) => index == 2).Single();
I have solved it like this.
var thename = 'Andrew';
db.collection.find({'name': {'$regex': thename,$options:'i'}});
If you want to query on 'case-insensitive exact matchcing' then you can go like this.
var thename = '^Andrew$';
db.collection.find({'name': {'$regex': thename,$options:'i'}});
Overhead typically reffers to the amount of extra resources (memory, processor, time, etc.) that different programming algorithms take.
For example, the overhead of inserting into a balanced Binary Tree could be much larger than the same insert into a simple Linked List (the insert will take longer, use more processing power to balance the Tree, which results in a longer percieved operation time by the user).
The != operator most certainly does exist! It is an alias for the standard <>
operator.
Perhaps your fields are not actually empty strings, but instead NULL
?
To compare to NULL
you can use IS NULL
or IS NOT NULL
or the null safe equals operator <=>
.
you can use WMI in .net too but you're then dependent on the wmi service running etc. Sometimes it works locally, but then fail when the same code is run on servers. I believe that's a namespace issue, related to the "names" whose values you're reading.
With Lamma it looks like this in Java:
for (Date d: Dates.from(2014, 6, 29).to(2014, 7, 1).build()) {
System.out.println(d);
}
and the output is:
Date(2014,6,29)
Date(2014,6,30)
Date(2014,7,1)
Each directive's controller
function is called whenever a new related element is instantiated.
Officially, the controller
function is where one:
Again, it is important to remember that if the directive involves an isolated scope, any properties within it that inherit from the parent scope are not yet available.
As described in this blog post, here is a method to round the corners of a UIView:
+(void)roundView:(UIView *)view onCorner:(UIRectCorner)rectCorner radius:(float)radius
{
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:view.bounds
byRoundingCorners:rectCorner
cornerRadii:CGSizeMake(radius, radius)];
CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
maskLayer.frame = view.bounds;
maskLayer.path = maskPath.CGPath;
[view.layer setMask:maskLayer];
[maskLayer release];
}
The cool part about it is that you can select which corners you want rounded up.
With a default option having selected attribute
<select>
<option value="" selected>Choose your city</option>
<option value ="sydney">Sydney</option>
<option value ="melbourne">Melbourne</option>
<option value ="cromwell">Cromwell</option>
<option value ="queenstown">Queenstown</option>
</select>
This way works:
class A
{
struct Wrap
{
A& a;
Wrap(A& aa) aa(a) {}
operator int() { return a.value; }
operator std::string() { stringstream ss; ss << a.value; return ss.str(); }
}
Wrap operator*() { return Wrap(*this); }
};
You can also specify context location relatively to current classpath, which may be preferable
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
If for matching identical images - code for L2 distance
// Compare two images by getting the L2 error (square-root of sum of squared error).
double getSimilarity( const Mat A, const Mat B ) {
if ( A.rows > 0 && A.rows == B.rows && A.cols > 0 && A.cols == B.cols ) {
// Calculate the L2 relative error between images.
double errorL2 = norm( A, B, CV_L2 );
// Convert to a reasonable scale, since L2 error is summed across all pixels of the image.
double similarity = errorL2 / (double)( A.rows * A.cols );
return similarity;
}
else {
//Images have a different size
return 100000000.0; // Return a bad value
}
Fast. But not robust to changes in lighting/viewpoint etc. Source
I had the same problem. I was running out of space.
Deleting old device simulators did NOT help.
My space issue was caused by xCode. It kept a copy of every iOS version on my macOS since I had installed xCode.
Delete the iOS version you don't want and free up disk space. I saved 50GB+ of space.
NOTE -> can't you see ~/Library
inside Finder
? It is hidden by default. Use Terminal
and type cd ~/Library/Developer/Xcode/iOS\ DeviceSupport/
or google how to see hidden folders.
NOTE -> if you have multiple users on a single macOS machine, make sure to find the directory ONLY with the user account that originally installed xCode.
In my case, this problem occured because I did npm install
with another system user in my project folder before. Gulp was already installed globally. After deleting folder /node_modules/ in my project, and running npm install
with the current user, it worked.
Variables names are only locally meaningful.
Once you hit
return s1,s2,s3,s4
at the end of the method, Python constructs a tuple with the values of s1, s2, s3 and s4 as its four members at index 0, 1, 2 and 3 - NOT a dictionary of variable names to values, NOT an object with variable names and their values, etc.
If you want the variable names to be meaningful after you hit return
in the method, you must create an object or dictionary.
Conditional comment is a comment starts with <!--[if IE]>
which couldn't be read by any browser except IE.
from 2011 Conditional comment isn't supported starting form IE 10 as announced by Microsoft in that time https://msdn.microsoft.com/en-us/library/hh801214(v=vs.85).aspx
The only option to use the Conditional comments is to request IE to run your site as IE 9 which supports the Conditional comments.
you can write your own css and/or js files for ie only and other browsers won't load or execute it.
this code snippet shows how to make IE 10 or 11 run ie-only.css and ie-only.js which contains custom codes to solve IE compatibility issues.

lots of correct answers, but as I landed here to copy & paste a folder rename with history, I found that this
git mv <old name> <new name>
will move the old folder (itself) to nest within the new folder
while
git mv <old name>/ <new name>
(note the '/') will move the nested content from the old folder to the new folder
both commands didn't copy along the history of nested files. I eventually renamed each nested folder individually ?
git mv <old name>/<nest-folder> <new name>/<nest-folder>
What you see is the interpreter echoing back the return value of next()
in addition to i
being printed each iteration:
>>> a = iter(list(range(10)))
>>> for i in a:
... print(i)
... next(a)
...
0
1
2
3
4
5
6
7
8
9
So 0
is the output of print(i)
, 1
the return value from next()
, echoed by the interactive interpreter, etc. There are just 5 iterations, each iteration resulting in 2 lines being written to the terminal.
If you assign the output of next()
things work as expected:
>>> a = iter(list(range(10)))
>>> for i in a:
... print(i)
... _ = next(a)
...
0
2
4
6
8
or print extra information to differentiate the print()
output from the interactive interpreter echo:
>>> a = iter(list(range(10)))
>>> for i in a:
... print('Printing: {}'.format(i))
... next(a)
...
Printing: 0
1
Printing: 2
3
Printing: 4
5
Printing: 6
7
Printing: 8
9
In other words, next()
is working as expected, but because it returns the next value from the iterator, echoed by the interactive interpreter, you are led to believe that the loop has its own iterator copy somehow.
Although this question is old, it is still asked by many who use MSYS2.
I started to use it this year to replace CygWin, and I'm getting pretty satisfied.
To install make
, open the MSYS2 shell and type the following commands:
# Update the package database and core system packages
pacman -Syu
# Close shell and open again if needed
# Update again
pacman -Su
# Install make
pacman -S make
# Test it (show version)
make -v
based on swift:
let alertCtr = UIAlertController(title:"Title", message:"Message", preferredStyle: .Alert)
let Cancel = AlertAction(title:"remove", style: .Default, handler: {(UIAlertAction) -> Void in })
let Remove = UIAlertAction(title:"remove", style: .Destructive, handler:{(UIAlertAction)-> Void
inself.colorLabel.hidden = true
})
alertCtr.addAction(Cancel)
alertCtr.addAction(Remove)
self.presentViewController(alertCtr, animated:true, completion:nil)}
JFrame and JApplet are top level containers. If you wish to create a desktop application, you will use JFrame and if you plan to host your application in browser you will use JApplet.
JComponent is an abstract class for all Swing components and you can use it as the base class for your new component. JPanel is a simple usable component you can use for almost anything.
Since this is for a fun project, the simplest way for you is to work with JPanel and then host it inside JFrame or JApplet. Netbeans has a visual designer for Swing with simple examples.
This is about nine years late, but randojs.com makes this a simple one-liner:

You just need to add this to the head of your html document, and you can do pretty much whatever you want with randomness easily. Random values from arrays, random jquery elements, random properties from objects, and even preventing repetitions if needed.

Try the sp_foreachdb procedure.
foreach
:
foreach (var money in myMoney) {
Console.WriteLine("Amount is {0} and type is {1}", money.amount, money.type);
}
Alternatively, because it is a List<T>
.. which implements an indexer method []
, you can use a normal for
loop as well.. although its less readble (IMO):
for (var i = 0; i < myMoney.Count; i++) {
Console.WriteLine("Amount is {0} and type is {1}", myMoney[i].amount, myMoney[i].type);
}
First, convert the string into a timestamp:
$timestamp = strtotime($string);
Then do a
date("Y-m-d H:i:s", $timestamp);
break
breaks out of a loop, not an if
statement, as others have pointed out. The motivation for this isn't too hard to see; think about code like
for item in some_iterable:
...
if break_condition():
break
The break
would be pretty useless if it terminated the if
block rather than terminated the loop -- terminating a loop conditionally is the exact thing break
is used for.
In python 3, reload
is no longer a built in function.
If you are using python 3.4+ you should use reload
from the importlib
library instead:
import importlib
importlib.reload(some_module)
If you are using python 3.2 or 3.3 you should:
import imp
imp.reload(module)
instead. See http://docs.python.org/3.0/library/imp.html#imp.reload
If you are using ipython
, definitely consider using the autoreload
extension:
%load_ext autoreload
%autoreload 2
I recently got this error. I had compiled the binary with -O3. Google told me that this means "illegal opcode", which seemed fishy to me. I then turned off all optimizations and reran. Now the error transformed to a segfault. Hence by setting -g and running valgrind I tracked the source down and fixed it. Reenabling all optimizations showed no further appearances of illegal instruction 4.
Apparently, optimizing wrong code can yield weird results.
I wrapped this up into an extension class, which allows you to call:
myDataTable.WriteToCsvFile("C:\\MyDataTable.csv");
on any DataTable.
public static class DataTableExtensions
{
public static void WriteToCsvFile(this DataTable dataTable, string filePath)
{
StringBuilder fileContent = new StringBuilder();
foreach (var col in dataTable.Columns)
{
fileContent.Append(col.ToString() + ",");
}
fileContent.Replace(",", System.Environment.NewLine, fileContent.Length - 1, 1);
foreach (DataRow dr in dataTable.Rows)
{
foreach (var column in dr.ItemArray)
{
fileContent.Append("\"" + column.ToString() + "\",");
}
fileContent.Replace(",", System.Environment.NewLine, fileContent.Length - 1, 1);
}
System.IO.File.WriteAllText(filePath, fileContent.ToString());
}
}
As others have mentioned, using an XML library is the easiest way. If you do want to escape yourself, you could look into StringEscapeUtils
from the Apache Commons Lang library.
If you are trying to use AngularJs 1.6.6 as of 21/10/2017 the following parameter works as .success and has been depleted. The .then() method takes two arguments: a response and an error callback which will be called with a response object.
$scope.login = function () {
$scope.btntext = "Please wait...!";
$http({
method: "POST",
url: '/Home/userlogin', // link UserLogin with HomeController
data: $scope.user
}).then(function (response) {
console.log("Result value is : " + parseInt(response));
data = response.data;
$scope.btntext = 'Login';
if (data == 1) {
window.location.href = '/Home/dashboard';
}
else {
alert(data);
}
}, function (error) {
alert("Failed Login");
});
The above snipit works for a login page.
You did not do anything wrong here, it will any other thing that is overriding the image size.
You can check this working fiddle.
And in this fiddle I have alter the image size using %
, and it is working.
Also try using this code:
<img src="image.jpg" style="width: 50%; height: 50%"/>?
Here is the example fiddle.
Well, this is an open question, and I have two aspects that I want to touch on: when to add assertions and how to write the error messages.
To explain it to a beginner - assertions are statements which can raise errors, but you won't be catching them. And they normally should not be raised, but in real life they sometimes do get raised anyway. And this is a serious situation, which the code cannot recover from, what we call a 'fatal error'.
Next, it's for 'debugging purposes', which, while correct, sounds very dismissive. I like the 'declaring invariants, which should never be violated' formulation better, although it works differently on different beginners... Some 'just get it', and others either don't find any use for it, or replace normal exceptions, or even control flow with it.
In Python, assert
is a statement, not a function! (remember assert(False, 'is true')
will not raise. But, having that out of the way:
When, and how, to write the optional 'error message'?
This acually applies to unit testing frameworks, which often have many dedicated methods to do assertions (assertTrue(condition)
, assertFalse(condition), assertEqual(actual, expected)
etc.). They often also provide a way to comment on the assertion.
In throw-away code you could do without the error messages.
In some cases, there is nothing to add to the assertion:
def dump(something): assert isinstance(something, Dumpable) # ...
But apart from that, a message is useful for communication with other programmers (which are sometimes interactive users of your code, e.g. in Ipython/Jupyter etc.).
Give them information, not just leak internal implementation details.
instead of:
assert meaningless_identifier <= MAGIC_NUMBER_XXX, 'meaningless_identifier is greater than MAGIC_NUMBER_XXX!!!'
write:
assert meaningless_identifier > MAGIC_NUMBER_XXX, 'reactor temperature above critical threshold'
or maybe even:
assert meaningless_identifier > MAGIC_NUMBER_XXX, f'reactor temperature({meaningless_identifier }) above critical threshold ({MAGIC_NUMBER_XXX})'
I know, I know - this is not a case for a static assertion, but I want to point to the informational value of the message.
This may be conroversial, but it hurts me to read things like:
assert a == b, 'a is not equal to b'
these are two contradictory things written next to eachother. So whenever I have an influence on the codebase, I push for specifying what we want, by using extra verbs like 'must' and 'should', and not to say what we don't want.
assert a == b, 'a must be equal to b'
Then, getting AssertionError: a must be equal to b
is also readable, and the statement looks logical in code. Also, you can get something out of it without reading the traceback (which can sometimes not even be available).
First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.
If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
'do something
End If
End If
After struggling for many days finally found a solution that works perfectly.
Mac OS open ~/Library folder (in your home directory) and delete the VirtulBox folder. This will remove all configurations and you can start the virtual box again!
Others look for .virtualbox folder in your home directory. Remove it and open VirtualBox should solve your issue.
Cheers!!
Just add this section to server, just before the location / {
location /your/folder/to/browse/ {
autoindex on;
}
You could define a mapping of air pressure to servo angle, for example:
def calc_angle(pressure, min_p=1000, max_p=1200): return 360 * ((pressure - min_p) / float(max_p - min_p)) angle = calc_angle(pressure)
This will linearly convert pressure
values between min_p
and max_p
to angles between 0 and 360 (you could include min_a
and max_a
to constrain the angle, too).
To pick a data structure, I wouldn't use a list but you could look up values in a dictionary:
d = {1000:0, 1001: 1.8, ...} angle = d[pressure]
but this would be rather time-consuming to type out!
After some testing this WILL remove the background color when deselected or cell is tapped a second time when table view Selection is set to "Multiple Selection". Also works when table view Style is set to "Grouped".
extension ViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if let cell = tableView.cellForRow(at: indexPath) {
cell.contentView.backgroundColor = UIColor.darkGray
}
}
}
Note: In order for this to work as you see below, your cell's Selection property can be set to anything BUT None.
Style: Plain, Selection: Single Selection
Style: Plain, Selection: Multiple Selection
Style: Grouped, Selection: Multiple Selection
For a smoother color transition, try some animation:
extension ViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if let cell = tableView.cellForRow(at: indexPath) {
UIView.animate(withDuration: 0.3, animations: {
cell.contentView.backgroundColor = UIColor.darkGray
})
}
}
}
You may notice the icon and text color also changing when cell is selected. This happens automatically when you set the UIImage and UILabel Highlighted properties
UIImage
UILabel
Just supply a color for the Highlighted property:

Try this (subquery):
SELECT * FROM terms WHERE id IN
(SELECT term_id FROM terms_relation WHERE taxonomy = "categ")
Or you can try this (JOIN):
SELECT t.* FROM terms AS t
INNER JOIN terms_relation AS tr
ON t.id = tr.term_id AND tr.taxonomy = "categ"
If you want to receive all fields from two tables:
SELECT t.id, t.name, t.slug, tr.description, tr.created_at, tr.updated_at
FROM terms AS t
INNER JOIN terms_relation AS tr
ON t.id = tr.term_id AND tr.taxonomy = "categ"

The Request Payload - or to be more precise: payload body of a HTTP Request
- is the data normally send by a POST or PUT Request.
It's the part after the headers and the CRLF
of a HTTP Request.
A request with Content-Type: application/json
may look like this:
POST /some-path HTTP/1.1
Content-Type: application/json
{ "foo" : "bar", "name" : "John" }
If you submit this per AJAX the browser simply shows you what it is submitting as payload body. That’s all it can do because it has no idea where the data is coming from.
If you submit a HTML-Form with method="POST"
and Content-Type: application/x-www-form-urlencoded
or Content-Type: multipart/form-data
your request may look like this:
POST /some-path HTTP/1.1
Content-Type: application/x-www-form-urlencoded
foo=bar&name=John
In this case the form-data is the request payload. Here the Browser knows more: it knows that bar is the value of the input-field foo of the submitted form. And that’s what it is showing to you.
So, they differ in the Content-Type
but not in the way data is submitted. In both cases the data is in the message-body. And Chrome distinguishes how the data is presented to you in the Developer Tools.
Try listening for events in the parent document and passing the event to a handler in the iframe document.
Anyway, I was following my workflow on a recent branch, and when I tried to merge it back to master, it all went to hell. There were tons of conflicts with things that should have not mattered. The conflicts just made no sense to me. It took me a day to sort everything out, and eventually culminated in a forced push to the remote master, since my local master has all conflicts resolved, but the remote one still wasn't happy.
In neither your partner's nor your suggested workflows should you have come across conflicts that didn't make sense. Even if you had, if you are following the suggested workflows then after resolution a 'forced' push should not be required. It suggests that you haven't actually merged the branch to which you were pushing, but have had to push a branch that wasn't a descendent of the remote tip.
I think you need to look carefully at what happened. Could someone else have (deliberately or not) rewound the remote master branch between your creation of the local branch and the point at which you attempted to merge it back into the local branch?
Compared to many other version control systems I've found that using Git involves less fighting the tool and allows you to get to work on the problems that are fundamental to your source streams. Git doesn't perform magic, so conflicting changes cause conflicts, but it should make it easy to do the write thing by its tracking of commit parentage.
Make sure storage folder with write previlege (chmod o+w), work for me like a charm.
If you want to install PHP extensions in ubuntu.
first know which PHP version is active.
php -v
After that install needed plugin using this command.
sudo apt install php7.0-bcmath
you can replace php7.0-bcmath to php-PHPVersion-extensionName
conda
is both a command line tool, and a python package.
Miniconda installer = Python + conda
Anaconda installer = Python + conda
+ meta package anaconda
meta Python pkg anaconda
= about 160 Python pkgs for daily use in data science
Anaconda installer = Miniconda installer + conda install anaconda
conda
is a python manager and an environment manager, which makes it possible to
conda install flake8
conda create -n myenv python=3.6
Miniconda installer = Python + conda
conda
, the package manager and environment manager, is a Python package. So Python is installed. Cause conda distribute Python interpreter with its own libraries/dependencies but not the existing ones on your operating system, other minimal dependencies like openssl
, ncurses
, sqlite
, etc are installed as well.
Basically, Miniconda is just conda
and its minimal dependencies. And the environment where conda
is installed is the "base" environment, which is previously called "root" environment.
Anaconda installer = Python + conda
+ meta package anaconda
meta Python package anaconda
= about 160 Python pkgs for daily use in data science
Meta packages, are packages that do NOT contain actual softwares and simply depend on other packages to be installed.
Download an anaconda
meta package from Anaconda Cloud and extract the content from it. The actual 160+ packages to be installed are listed in info/recipe/meta.yaml
.

The pre-installed packages from meta pkg anaconda
are mainly for web scraping and data science. Like requests
, beautifulsoup
, numpy
, nltk
, etc.
If you have a Miniconda installed, conda install anaconda
will make it same as an Anaconda installation, except that the installation folder names are different.
Miniconda2 v.s. Miniconda. Anaconda2 v.s. Anaconda.
2
means the bundled Python interpreter for conda
in the "base" environment is Python 2, but not Python 3.
An alternative would be to place your regexp in non-capturing parentheses. Then make that expression optional using the ?
qualifier, which will look for 0 (i.e. empty string) or 1 instances of the non-captured group.
For example:
/(?: some regexp )?/
In your case the regular expression would look something like this:
/^(?:[\w\.\-]+@([\w\-]+\.)+[a-zA-Z]+)?$/
No |
"or" operator necessary!
Here is the Mozilla documentation for JavaScript Regular Expression syntax.
Command:
foo >> output.txt 2>&1
appends to the output.txt file, without replacing the content.
You can also use:
sdiff file1 file2
To display differences side by side within your terminal!
In my opinion if you got the resources to use, then go with eclipse. NetBeans which is awesome like eclipse is another best option, these are the only 2 I've ever used (loved, needed, wanted)
Eclipse is hands down the most popular, and for good reason!
Hope this helps.
In terms of the XML format for log4net, you need not worry about ex.ToString() for the logs. Simply pass the exception object itself and log4net does the rest do give you all of the details in its pre-configured XML format. The only thing I run into on occasion is new line formatting, but that's when I'm reading the files raw. Otherwise parsing the XML works great.
You can add a new formula for unique record count
=IF(COUNTIF($A$2:A2,A2)>1,0,1)
Now you can use a pivot table and get a SUM
of unique record count.
This solution works best if you have two or more rows where the same value exist, but you want the pivot table to report an unique count.
Yes you can.
You need to add in the first controller:
YourController controller = loader.getController();
controller.setclient(client);
Then in the second one declare a client, then at the bottom of your controller:
public void setclien(Client c) {
this.client = c;
}
Another way to install python3 is using wget. Below are the steps for installation.
wget http://www.python.org/ftp/python/3.3.5/Python-3.3.5.tar.xz
tar xJf ./Python-3.3.5.tar.xz
cd ./Python-3.3.5
./configure --prefix=/opt/python3.3
make && sudo make install
Also,one can create an alias for the same using
echo 'alias py="/opt/python3.3/bin/python3.3"' >> ~/.bashrc
Now open a new terminal and type py and press Enter.
SimpleDateFormat("MM-dd-yyyy");
instead of
SimpleDateFormat("mm-dd-yyyy");
because MM points Month
, mm points minutes
SimpleDateFormat sm = new SimpleDateFormat("MM-dd-yyyy");
String strDate = sm.format(myDate);
Like that:
SELECT p.*, a.street, a.city FROM persons AS p
JOIN address AS a ON p.id = a.person_id
WHERE a.zip = '97299'
You need to add -L/opt/lib
to tell ld
to look there for shared objects.
removeChild
should be invoked on the parent, i.e.:
parent.removeChild(child);
In your example, you should be doing something like:
if (frameid) {
frameid.parentNode.removeChild(frameid);
}
You can reference Microsoft.VisualBasic.dll
.
Then using the code below.
Microsoft.VisualBasic.Interaction.InputBox("Question?","Title","Default Text");
Alternatively, by adding a using
directive allowing for a shorter syntax in your code (which I'd personally prefer).
using Microsoft.VisualBasic;
...
Interaction.InputBox("Question?","Title","Default Text");
Or you can do what Pranay Rana suggests, that's what I would've done too...
if you want to use MySQLdb first you have to install pymysql on your pc by typing in cmd of windows
pip install pymysql
then in python shell, type
import pymysql
pymysql.install_as_MySQLdb()
import MySQLdb
db = MySQLdb.connect("localhost" , "root" , "password")
this will establish the connection.
malloc will do.
int rows = 20;
int cols = 20;
int *array;
array = malloc(rows * cols * sizeof(int));
Refer the below article for help:-
http://courses.cs.vt.edu/~cs2704/spring00/mcquain/Notes/4up/Managing2DArrays.pdf
You'll want to use the clone()
method in order to get a deep copy of the element:
$(function(){
var $button = $('.button').clone();
$('.package').html($button);
});
Full demo: http://jsfiddle.net/3rXjx/
From the jQuery docs:
The .clone() method performs a deep copy of the set of matched elements, meaning that it copies the matched elements as well as all of their descendant elements and text nodes. When used in conjunction with one of the insertion methods, .clone() is a convenient way to duplicate elements on a page.
The below code worked for me in my chat application to handle multiple mouse click triggering events more than once.
if (!e.originalEvent.detail || e.originalEvent.detail == 1)
{ // Your code logic }
Maybe the following is what you are looking for:
SELECT name, pathfilename
FROM table1
NATURAL JOIN table2
NATURAL JOIN table3
WHERE name = 'John';
i think this is also because of incorrect compilation..
so for linux (ubuntu).....
javac file.java
java file
You can try in this way. I had applied this in my case.
#include<stdio.h>
struct name
{
char first[20];
char last[30];
};
//globally
// struct name sara={"Sara","Black"};
int main()
{
//locally
struct name sara={"Sara","Black"};
printf("%s",sara.first);
printf("%s",sara.last);
}
The almighty switch
works well here:
'one
two
three' > file
$regex = '^t'
switch -regex -file file {
$regex { "line is $_" }
}
Output:
line is two
line is three
The much longer example below combines some of the useful snippets above:
It could still do with a lot of work to make it better (better error-handling, general cleaning up), but it hopefully provides a good start.

Currently, I am using Ubuntu 16.04 LTS. Me too was facing same problem while Fetching the Postgress Database values using Php so i resolved it by using the below commands.
Mine PHP version is 7.0, so i tried the below command.
apt-get install php-pgsql
Remember to restart Apache.
/etc/init.d/apache2 restart
You can simply use the method change
of JQuery to get the value of the current radio checked with the following code:
$(document).on('change', '[type="radio"]', function() {
var currentlyValue = $(this).val(); // Get the radio checked value
alert('Currently value: '+currentlyValue); // Show a alert with the current value
});
You can change the selector '[type="radio"]'
for a class or id that you want.
You can use my solution, this is the most convenient way. It’s also free.
Create state machine in three steps :
1. Create scheme in node editor and load it in your project using library
StateMachine stateMachine = new StateMachine("scheme.xml");
2. Describe your app logic on events?
stateMachine.GetState("State1").OnExit(Action1); stateMachine.GetState("State2").OnEntry(Action2); stateMachine.GetTransition("Transition1").OnInvoke(Action3); stateMachine.OnChangeState(Action4);
3. Run the state machine
stateMachine.Start();
