Are there situations in which sys.stdout.write() is preferable to print?
For example I'm working on small function which prints stars in pyramid format upon passing the number as argument, although you can accomplish this using end="" to print in a separate line, I used sys.stdout.write in co-ordination with print to make this work. To elaborate on this stdout.write prints in the same line where as print always prints its contents in a separate line.
import sys
def printstars(count):
if count >= 1:
i = 1
while (i <= count):
x=0
while(x<i):
sys.stdout.write('*')
x = x+1
print('')
i=i+1
printstars(5)
When installing make sure that under Tcl/Tk
you select Will be installed on hard drive
. If it is installing with a cross at the left then Tkinter will not be installed.
The same goes for Python 3:
To create simple hover enlarge plugin, try this. (DEMO)
HTML
<div id="content">
<img src="http://www.freevectorgallery.com/wp-content/uploads/2011/10/Vintage-Microphone- 11395-large.jpg" style="width:50%;" />
</div>
js
$(function () {
$('#content img').hover(function () {
$(this).toggle(function () {
$(this).width('70%');
});
});
});
Your original rewrite should almost work. I'm not sure why it would be redirecting, but I think what you really want is just
rewrite ^ /base.html break;
You should be able to put that in a location or directly in the server.
You can call multiple functions with ';'
ng-click="edit($index); open()"
You can simply traverse through the object and return if a match is found.
Here is the code:
returnKeyforValue : function() {
var JsonObj= { "one":1, "two":2, "three":3, "four":4, "five":5 };
for (key in JsonObj) {
if(JsonObj[key] === "Keyvalue") {
return key;
}
}
}
A null value and an empty string both result in no value being indexed, in which case you can use the exists
filter
curl -XGET 'http://127.0.0.1:9200/test/test/_search?pretty=1' -d '
{
"query" : {
"constant_score" : {
"filter" : {
"exists" : {
"field" : "myfield"
}
}
}
}
}
'
Or in combination with (eg) a full text search on the title
field:
curl -XGET 'http://127.0.0.1:9200/test/test/_search?pretty=1' -d '
{
"query" : {
"filtered" : {
"filter" : {
"exists" : {
"field" : "myfield"
}
},
"query" : {
"match" : {
"title" : "search keywords"
}
}
}
}
}
'
The short version is that you cannot use variable-width patterns in lookbehinds using Python's re
module. There is no way to change this:
>>> import re
>>> re.sub("(?<=foo)bar(?=baz)", "quux", "foobarbaz")
'fooquuxbaz'
>>> re.sub("(?<=fo+)bar(?=baz)", "quux", "foobarbaz")
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
re.sub("(?<=fo+)bar(?=baz)", "quux", string)
File "C:\Development\Python25\lib\re.py", line 150, in sub
return _compile(pattern, 0).sub(repl, string, count)
File "C:\Development\Python25\lib\re.py", line 241, in _compile
raise error, v # invalid expression
error: look-behind requires fixed-width pattern
This means that you'll need to work around it, the simplest solution being very similar to what you're doing now:
>>> re.sub("(fo+)bar(?=baz)", "\\1quux", "foobarbaz")
'fooquuxbaz'
>>>
>>> # If you need to turn this into a callable function:
>>> def replace(start, replace, end, replacement, search):
return re.sub("(" + re.escape(start) + ")" + re.escape(replace) + "(?=" + re.escape + ")", "\\1" + re.escape(replacement), search)
This doesn't have the elegance of the lookbehind solution, but it's still a very clear, straightforward one-liner. And if you look at what an expert has to say on the matter (he's talking about JavaScript, which lacks lookbehinds entirely, but many of the principles are the same), you'll see that his simplest solution looks a lot like this one.
Kotlin style.
startActivity(Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS).apply {
data = Uri.fromParts("package", packageName, null)

Yes you can; it works on Android too:
tel: phone_number
Calls the entered phone number. Valid telephone numbers as defined in the IETF RFC 3966 are accepted. Valid examples include the following:* tel:2125551212 * tel: (212) 555 1212
The Android browser uses the Phone app to handle the “tel” scheme, as defined by RFC 3966.
Clicking a link like:
<a href="tel:2125551212">2125551212</a>
on Android will bring up the Phone app and pre-enter the digits for 2125551212 without autodialing.
Have a look to RFC3966

Note: SYSDATE - returns only date, i.e., "yyyy-mm-dd" is not correct. SYSDATE returns the system date of the database server including hours, minutes, and seconds. For example:
SELECT SYSDATE FROM DUAL; will return output similar to the following: 12/15/2017 12:42:39 PM
To auto indent on Sublime text 3 with a key bind try going to
Preferences > Key Bindings - users
And adding this code between the square brackets
{"keys": ["alt+shift+f"], "command": "reindent", "args": {"single_line": false}}
it sets shift + alt + f to be your full page auto indent.
Source here
Note: if this doesn't work correctly then you should convert your indentation to tabs. Also comments in your code can push your code to the wrong indentation level and may have to be moved manually.
Usage:
select replace_foreign_key('user_rates_posts', 'post_id', 'ON DELETE CASCADE');
Function:
CREATE OR REPLACE FUNCTION
replace_foreign_key(f_table VARCHAR, f_column VARCHAR, new_options VARCHAR)
RETURNS VARCHAR
AS $$
DECLARE constraint_name varchar;
DECLARE reftable varchar;
DECLARE refcolumn varchar;

JOIN information_schema.key_column_usage AS kcu
ON tc.constraint_name = kcu.constraint_name
JOIN information_schema.constraint_column_usage AS ccu
ON ccu.constraint_name = tc.constraint_name
WHERE constraint_type = 'FOREIGN KEY'
AND tc.table_name= f_table AND kcu.column_name= f_column

Be aware: this function won't copy attributes of initial foreign key. It only takes foreign table name / column name, drops current key and replaces with new one.

This way I implement upload file to web API in project.
I share for whom concern.
const formData: FormData = new FormData();
formData.append('Image', image, image.name);
formData.append('ComponentId', componentId);
return this.http.post('/api/dashboard/UploadImage', formData);
Step by step
ASP.NET Web API
[HttpPost]
[Route("api/dashboard/UploadImage")]
public HttpResponseMessage UploadImage()
{
string imageName = null;
var httpRequest = HttpContext.Current.Request;
//Upload Image
var postedFile = httpRequest.Files["Image"];
//Create custom filename
if (postedFile != null)
{
imageName = new String(Path.GetFileNameWithoutExtension(postedFile.FileName).Take(10).ToArray()).Replace(" ", "-");
imageName = imageName + DateTime.Now.ToString("yymmssfff") + Path.GetExtension(postedFile.FileName);
var filePath = HttpContext.Current.Server.MapPath("~/Images/" + imageName);
postedFile.SaveAs(filePath);
}
}
HTML form

Firstobject's free XML editor for Windows is called foxe is a great tool.
Open or paste your XML into it and press F8 to indent (you may need to set the number of indent spaces as it may default to 0).
It looks simple, however it contains a custom written XML parser written in C++ that allows it to work efficiently with very large XML files easily (unlike some expensive "espionage" related tools I've used).
From the product page:
The full Visual C++ source code for this firstobject XML editor (including the CDataEdit gigabyte edit control MFC component) is available as part of the Advanced CMarkup Developer License. It allows developers to implement custom XML handling functions such as validation, transformation, beautify, and reporting for their own purposes.

If you want to print multiple rows, you can iterate through the result by using a cursor. e.g. print all names from sys.database_principals
DECLARE @name nvarchar(128)
DECLARE cur CURSOR FOR
SELECT name FROM sys.database_principals
OPEN cur
FETCH NEXT FROM cur INTO @name;
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT @name
FETCH NEXT FROM cur INTO @name;
END
CLOSE cur;
DEALLOCATE cur;
If anyone stumblng here has problems with internal grid selection happening after OnSelectionChanged - after unsuccessfully trying out all the selection setters for a dozen hours the only thing that worked for me was reloading and repopulating DataGrid along with selected item. Not elegant at all, but at this point I'm not sure if a better solution exists in my situation.
datagrid.ItemsSource = null
datagrid.ItemsSource = items;
datagrid.SelectedItem = selectedItem;
You can delete a file as follow:
File file = new File("your sdcard path is here which you want to delete");
file.delete();
if (file.exists()){
file.getCanonicalFile().delete();
if (file.exists()){
deleteFile(file.getName());
}
}
All the plugins listed above have a serious problem - they are using the virtual folders implemented via WordPress Taxonomy API, while X4 Media Library is using the real physical folders located in your wp-content/uploads
directory on the server.
What happens when you put some images to the folder using any plugin listed above? Because of they are using the virtual folders, the destinition folder is represented as a taxonomy tag in the database, so they just assign the folder's tag to moved files.
There are no real modifications happened on your physical disk, in the wp-content/uploads
directory. You can see that images URL didn't change when you move them to another folder.
Alternatively, with X4 Media Library if you put some files to the folder they will really be moved to that physical folder on your disk, in the wp-content/uploads
directory, and the images URL will be changed automatically.
Moreover, this plugin will make sure that all the links associated with these images in all your Posts, Pages and other custom types will be updated automatically.
I suggest writing a little script and doing multiple searches with Grep. I've never found a way to search for multiple patterns, and believe me, I've looked!
Like so, your shell file, with an embedded string:
#!/bin/bash
grep *A6* "Alex A1 Alex A6 Alex A7 Bob A1 Chris A9 Chris A6";
grep *A7* "Alex A1 Alex A6 Alex A7 Bob A1 Chris A9 Chris A6";
grep *A8* "Alex A1 Alex A6 Alex A7 Bob A1 Chris A9 Chris A6";
Then run by typing myshell.sh.
If you want to be able to pass in the string on the command line, do it like this, with a shell argument--this is bash notation btw:
#!/bin/bash
$stingtomatch = "${1}";
grep *A6* "${stingtomatch}";
grep *A7* "${stingtomatch}";
grep *A8* "${stingtomatch}";
And so forth.
If there are a lot of patterns to match, you can put it in a for loop.
VirtualBox is a virtualizer, not an emulator. (The name kinda gives it away.) I.e. it can only virtualize a CPU that is actually there, not emulate one that isn't. In particular, VirtualBox can only virtualize x86 and AMD64 CPUs. iOS only runs on ARM CPUs.

also if you already have various VENV's created with different versions of Python you switch to the desired Kernel by choosing KERNEL >> CHANGE KERNEL from within the JupyterNotebook menu... JupyterNotebookScreencapture
Also to install ipykernel within an existing CONDA Virtual Environment -
$ /path/to/python -m ipykernel install --help
usage: ipython-kernel-install [-h] [--user] [--name NAME]
[--display-name DISPLAY_NAME]
[--profile PROFILE] [--prefix PREFIX]
[--sys-prefix]
Install the IPython kernel spec.
optional arguments: -h, --help show this help message and exit --user Install for the current user instead of system-wide --name NAME Specify a name for the kernelspec. This is needed to have multiple IPython kernels at the same time. --display-name DISPLAY_NAME Specify the display name for the kernelspec. This is helpful when you have multiple IPython kernels. --profile PROFILE Specify an IPython profile to load. This can be used to create custom versions of the kernel. --prefix PREFIX Specify an install prefix for the kernelspec. This is needed to install into a non-default location, such as a conda/virtual-env. --sys-prefix Install to Python's sys.prefix. Shorthand for --prefix='/Users/bussonniermatthias/anaconda'. For use in conda/virtual-envs.
Here's how I got it working:

run gpedit.msc
(as Admin) and enable the following setting:
gpedit->Local->Computer->Windows Comp->ActiveX Installer->ActiveX installation policy for sites in Trusted Zones

Run gpupdate
Relaunch your Browser
NOTES: Windows 10 EDGE don't have trusted sites, so you have to use IE 11. Lots of folk moaning about that!
Your getElementById
is looking for an element with id "myclass", but in your html the id of the DIV is showhide
. Change to:
<script>
function changeclass() {
var NAME = document.getElementById("showhide")
NAME.className="mynewclass"
}
</script>
Unless you are trying to target a different element with the id "myclass", then you need to make sure such an element exists.
Find all word and space characters up to and including a -
^[\w ]+-
Width auto
The initial width of a block level element like div or p is auto. This makes it expand to occupy all available horizontal space within its containing block. If it has any horizontal padding or border, the widths of those do not add to the total width of the element.
Width 100%
On the other hand, if you specify width:100%, the element’s total width will be 100% of its containing block plus any horizontal margin, padding and border (unless you’ve used box-sizing:border-box, in which case only margins are added to the 100% to change how its total width is calculated). This may be what you want, but most likely it isn’t.
To visualise the difference see this picture:
In docker container phpmyadmin/phpmyadmin no php.ini file. But there are two files : php.ini-debug and php.ini-production
To solve the problem, simply rename one of the files to php.ini and restart docker container.
Now java 9 has factory Methods for Immutable List, Set, Map and Map.Entry .
In Java SE 8 and earlier versions, We can use Collections class utility methods like unmodifiableXXX to create Immutable Collection objects.
However these Collections.unmodifiableXXX methods are very tedious and verbose approach. To overcome those shortcomings, Oracle corp has added couple of utility methods to List, Set and Map interfaces.
Now in java 9 :- List and Set interfaces have “of()” methods to create an empty or no-empty Immutable List or Set objects as shown below:
Empty List Example
List immutableList = List.of();
Non-Empty List Example
List immutableList = List.of("one","two","three");
Your repository is broken. But you can probably fix it AND keep your edits:

rm -r your_repository_*

this(DEFAULT_VALUE); // delegate to other constructor
}
MyClass(int value) {

Simplest way for create SSL certificate
Open Firefox (I suppose it's also possible with Chrome, but it's easier for me with FF)
Visit your development site with a self-signed SSL certificate.
Click on the certificate (next to the site name)
Click on "More information"
Click on "View certificate"
Click on "Details"
Click on "Export..."
Choose "X.509 Certificate whith chain (PEM)", select the folder and name to save it and click "Save"
Go to command line, to the directory where you downloaded the pem file and execute "openssl x509 -inform PEM -outform DM -in .pem -out .crt"
Copy the .crt file to the root of the /sdcard folder inside your Android device Inside your Android device, Settings > Security > Install from storage.
It should detect the certificate and let you add it to the device Browse to your development site.
The first time it should ask you to confirm the security exception. That's all.
The certificate should work with any browser installed on your Android (Browser, Chrome, Opera, Dolphin...)
Remember that if you're serving your static files from a different domain (we all are page speed bitches) you also need to add the certificate for that domain.
String strLong = Long.toString(longNumber);
Simple and works fine :-)
following code is working fine for me:
import smtplib
to = '[email protected]'
gmail_user = '[email protected]'
gmail_pwd = 'yourpassword'
smtpserver = smtplib.SMTP("smtp.gmail.com",587)
smtpserver.ehlo()
smtpserver.starttls()
smtpserver.ehlo() # extra characters to permit edit
smtpserver.login(gmail_user, gmail_pwd)
header = 'To:' + to + '\n' + 'From: ' + gmail_user + '\n' + 'Subject:testing \n'
print header
msg = header + '\n this is test msg from mkyong.com \n\n'
smtpserver.sendmail(gmail_user, to, msg)
print 'done!'
smtpserver.quit()

I also tube that problem. But solve it by an instance of an image every time you change the source (image).
It seems that would be called onload only once. But this way, you can change image whenever you want.
function chageIcon(domImg,srcImage)
{
var img = new Image();
img.onload = function()
{
// Load completed
domImg.src = this.src;
};
img.src = srcImage;
}
Mode use.
chageIcon(document.getElementById("img"),"newIcon.png");
It seems to me the last line of your example code should simply be:
Task<Item> itsMe = o as Task<Item>;
Or am I missing something?
Just insert the argument between a double square bracket:
regressor.predict([[values]])
that worked for me

The one answer is fine but requires a little reading into. Especially with the new terminology "stop".
My Go -- organized by differences to make it useful in addition to the first answer by Daniel above:
1) negative indexes. Substring requires positive indexes and will set a negative index to 0. Slice's negative index means the position from the end of the string.
"1234".substring(-2, -1) == "1234".substring(0,0) == ""
"1234".slice(-2, -1) == "1234".slice(2, 3) == "3"
2) Swapping of indexes. Substring will reorder the indexes to make the first index less than or equal to the second index.
"1234".substring(3,2) == "1234".substring(2,3) == "3"
"1234".slice(3,2) == ""
General comment -- I find it weird that the second index is the position after the last character of the slice or substring. I would expect "1234".slice(2,2) to return "3". This makes Andy's confusion above justified -- I would expect "1234".slice(2, -1) to return "34". Yes, this means I'm new to Javascript. This means also this behavior:
"1234".slice(-2, -2) == "", "1234".slice(-2, -1) == "3", "1234".slice(-2, -0) == "" <-- you have to use length or omit the argument to get the 4.
"1234".slice(3, -2) == "", "1234".slice(3, -1) == "", "1234".slice(3, -0) == "" <-- same issue, but seems weirder.
My 2c.
Use a double-negative:
/[^\S\r\n]/
That is, not-not-whitespace (the capital S complements) or not-carriage-return or not-newline. Distributing the outer not (i.e., the complementing ^
in the character class) with De Morgan's law, this is equivalent to “whitespace but not carriage return or newline.” Including both \r
and \n
in the pattern correctly handles all of Unix (LF), classic Mac OS (CR), and DOS-ish (CR LF) newline conventions.
No need to take my word for it:
#! /usr/bin/env perl
use strict;
use warnings;

Note the exclusion of vertical tab, but this is addressed in v5.18.
Before objecting too harshly, the Perl documentation uses the same technique. A footnote in the “Whitespace” section of perlrecharclass reads
Prior to Perl v5.18,
\s
did not match the vertical tab.[^\S\cK]
(obscurely) matches what\s
traditionally did.
The same section of perlrecharclass also suggests other approaches that won’t offend language teachers’ opposition to double-negatives.
Outside locale and Unicode rules or when the /a
switch is in effect, “\s
matches [\t\n\f\r ]
and, starting in Perl v5.18, the vertical tab, \cK
.” Discard \r
and \n
to leave /[\t\f\cK ]/
for matching whitespace but not newline.
If your text is Unicode, use code similar to the sub below to construct a pattern from the table in the aforementioned documentation section.

The double-negative trick is also handy for matching alphabetic characters too. Remember that \w
matches “word characters,” alphabetic characters and digits and underscore. We ugly-Americans sometimes want to write it as, say,
if (/[A-Za-z]+/) { ... }
but a double-negative character-class can respect the locale:
if (/[^\W\d_]+/) { ... }
Expressing “a word character but not digit or underscore” this way is a bit opaque. A POSIX character-class communicates the intent more directly
if (/[[:alpha:]]+/) { ... }
or with a Unicode property as szbalint suggested
if (/\p{Letter}+/) { ... }
nginx "fails fast" when the client informs it that it's going to send a body larger than the client_max_body_size
by sending a 413 response and closing the connection.
Most clients don't read responses until the entire request body is sent. Because nginx closes the connection, the client sends data to the closed socket, causing a TCP RST.
If your HTTP client supports it, the best way to handle this is to send an Expect: 100-Continue
header. Nginx supports this correctly as of 1.2.7, and will reply with a 413 Request Entity Too Large
response rather than 100 Continue
if Content-Length
exceeds the maximum body size.
Maven or Ant? is a very similar question to this one, which should help you answer your questions.
What is Maven? on the official site.
edit: For a new/greenfield project, I'd recommend using Maven: "convention over configuration" will save you a decent chunk of time in writing and setting up build and deployment scripts. When you use ant, the build script tends to grow over time in length and complexity. For existing projects, it can be hard to shoehorn their configuration/layout into the Maven system.
For future reference Python is strongly typed. Unlike other dynamic languages, it will not automagically cast objects from one type or the other (say from str
to int
) so you must do this yourself. You'll like that in the long-run, trust me!
Finally, I have found a solution. It simply consists of overriding the value for colorControlActivated
, colorControlHighlight
and colorControlNormal
in your app theme definition and not your edittext style. Then, think to use this theme for whatever activity you desire. Below is an example:
<style name="Theme.App.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorControlNormal">#c5c5c5</item>
<item name="colorControlActivated">@color/accent</item>
<item name="colorControlHighlight">@color/accent</item>
</style>
Is this what you are looking for? Flexbox...
.container{_x000D_
display: flex;_x000D_
flex-flow: row wrap;_x000D_
justify-content: center;_x000D_
align-content: center;_x000D_
align-items: center;_x000D_
}_x000D_
.inside{_x000D_
height:100px;_x000D_
width:100px;_x000D_
background:gray;_x000D_
border:1px solid;_x000D_
}
_x000D_
<section class="container">_x000D_
<section class="inside">_x000D_

You have two options:
You can either put an anchor in your document as follows:
<a name="ref"></a>
Or else you give an id to a any HTML element:
<h1 id="ref">Heading</h1>
Then simply append the hash #ref
to the URL of your link to jump to the desired reference. Example:
<a href="document.html#ref">Jump to ref in document.html</a>
The best way is to import the image first and then use it.
import React, { Component } from 'react';
import logo from '../logo.svg';
export default class Header extends Component {
render() {
return (
<div className="row">
<div className="logo">
<img src={logo} width="100" height="50" />
</div>
</div>
);
}
}
cd <ANDROID_SDK_PATH>

sqlite3 <DB_NAME>

You can use the concept of selector. onFocus removes the hint.
android:hint="Email"
So when TextView
has focus, or has user input (i.e. not empty) the hint will not display.
Python prefers English keywords to punctuation. Use not x
, i.e. not os.path.exists(...)
. The same thing goes for &&
and ||
which are and
and or
in Python.
input()
by default takes the input in form of strings.
if (0<= vote <=24):
vote takes a string input (suppose 4
,5
,etc) and becomes uncomparable.
The correct way is: vote = int(input("Enter your message")
will convert the input to integer (4
to 4 or 5
to 5 depending on the input)
after spending a few hours searching for a solution, I decided to create my own. He it is:
function CustomInitSelect2(element, options) {
if (options.url) {
$.ajax({
type: 'GET',
url: options.url,
dataType: 'json'
}).then(function (data) {
element.select2({
data: data
});
if (options.initialValue) {
element.val(options.initialValue).trigger('change');
}
});
}
}
And you can initialize the selects using this function:
$('.select2').each(function (index, element) {
var item = $(element);
if (item.data('url')) {
CustomInitSelect2(item, {
url: item.data('url'),
initialValue: item.data('value')
});
}
else {
item.select2();
}
});
And of course, here is the html:
<select class="form-control select2" id="test1" data-url="mysite/load" data-value="123"></select>
If you hava a fact png (1MB for 400x400 etc.):
__import__("importlib").import_module("PIL.Image").open("out.png").save("out.png")
Use nm -a your.dylib
It will print all the symbols including globals
You can use boost graph library and cyclic dependencies. It has the solution for finding cycles with back_edge
function.
If you're using Webpack:
webpack.config.js:
plugins: [
<... your plugins here>,
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery",
"window.jQuery": "jquery",
"window.Tether": 'tether'
})
]
Use INDIRECT()
=SUM(INDIRECT(<start cell here> & ":" & <end cell here>))
The mail server on CentOS 6 and other IPv6 capable server platforms may be bound to IPv6 localhost (::1) instead of IPv4 localhost (127.0.0.1).
Typical symptoms:
[root@host /]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
[root@host /]# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 host ESMTP Exim 4.72 Wed, 14 Aug 2013 17:02:52 +0100
[root@host /]# netstat -plant | grep 25
tcp 0 0 :::25 :::* LISTEN 1082/exim
If this happens, make sure that you don't have two entries for localhost
in /etc/hosts
with different IP addresses, like this (bad) example:
[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
To avoid confusion, make sure you only have one entry for localhost
, preferably an IPv4 address, like this:
[root@host /]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4.localdomain4 localhost4
::1 localhost6 localhost6.localdomain6
Your curl
command is entirely wrong. You should be using the following
curl -H 'Authorization: token <MYTOKEN>' ...
That aside, that doesn't authorize your computer to clone the repository if in fact it is private. (Taking a look, however, indicates that it is not.) What you would normally do is the following:
git clone https://scuzzlebuzzle:<MYTOKEN>@github.com/scuzzlebuzzle/ol3-1.git --branch=gh-pages gh-pages
That will add your credentials to the remote created when cloning the repository. Unfortunately, however, you have no control over how Travis clones your repository, so you have to edit the remote like so.
# After cloning
cd gh-pages
git remote set-url origin https://scuzzlebuzzle:<MYTOKEN>@github.com/scuzzlebuzzle/ol3-1.git
That will fix your project to use a remote with credentials built in.
Warning: Tokens have read/write access and should be treated like passwords. If you enter your token into the clone URL when cloning or adding a remote,
Git writes it to your .git/config file in plain text, which is a security risk.
I tried to recreate the situation...
WebMethod
called Function1
expecting the following params: Function1(Contact Contact, string description, int amount)
Where Contact
is just a model that has getters and setters for id
and name
like in your case.
You can download the .NET sample WS at:
https://www.dropbox.com/s/6pz1w94a52o5xah/11593623.zip
This is what you need to do at PHP side:
(Tested and working)
<?php
// Create Contact class
class Contact {
public function __construct($id, $name)
{
$this->id = $id;
$this->name = $name;
}
}
// Initialize WS with the WSDL
$client = new SoapClient("http://localhost:10139/Service1.asmx?wsdl");
// Create Contact obj
$contact = new Contact(100, "John");
// Set request params
$params = array(
"Contact" => $contact,
"description" => "Barrel of Oil",
"amount" => 500,
);
// Invoke WS method (Function1) with the request params
$response = $client->__soapCall("Function1", array($params));
// Print WS response
var_dump($response);
?>
print_r($params)
you will see the following output, as your WS would expect:Array ( [Contact] => Contact Object ( [id] => 100 [name] => John ) [description] => Barrel of Oil [amount] => 500 )
(As you can see, Contact
object is not null
nor the other params. That means your request was successfully done from PHP side)
object(stdClass)[3] public 'Function1Result' => string 'Detailed information of your request! id: 100, name: John, description: Barrel of Oil, amount: 500' (length=98)
Happy Coding!
you can just add 1
<li v-for="(catalog, itemObjKey) in catalogs">this index : {{itemObjKey + 1}}</li>
to get the length of an array/objects
{{ catalogs.length }}
A little more generic solution (you can specify the number of parts you want, not just split 'in half'):
EDIT: updated post to handle odd list lengths
EDIT2: update post again based on Brians informative comments
def split_list(alist, wanted_parts=1):
length = len(alist)
return [ alist[i*length // wanted_parts: (i+1)*length // wanted_parts]
for i in range(wanted_parts) ]
A = [0,1,2,3,4,5,6,7,8,9]
print split_list(A, wanted_parts=1)
print split_list(A, wanted_parts=2)
print split_list(A, wanted_parts=8)
In C#, a base class' constructor runs before the derived class' constructor, so any instance fields that a derived class might use in the possibly-overridden virtual member are not initialized yet.
Do note that this is just a warning to make you pay attention and make sure it's all-right. There are actual use-cases for this scenario, you just have to document the behavior of the virtual member that it can not use any instance fields declared in a derived class below where the constructor calling it is.

IPython has profiles for configuration, located at ~/.ipython/profile_*
. The default profile is called profile_default
. Within this folder there are two primary configuration files:
ipython_config.py
ipython_kernel_config.py
Add the inline option for matplotlib to ipython_kernel_config.py
:
c = get_config()
# ... Any other configurables you want to set
c.InteractiveShellApp.matplotlib = "inline"
Usage of %pylab
to get inline plotting is discouraged.
It introduces all sorts of gunk into your namespace that you just don't need.
%matplotlib
on the other hand enables inline plotting without injecting your namespace. You'll need to do explicit calls to get matplotlib and numpy imported.
import matplotlib.pyplot as plt
import numpy as np
The small price of typing out your imports explicitly should be completely overcome by the fact that you now have reproducible code.
Try this:
Sub GetColumns()
Dim lnRow As Long, lnCol As Long
lnRow = 3 'For testing
lnCol = Sheet1.Cells(lnRow, 1).EntireRow.Find(What:="sds", LookIn:=xlValues, LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlNext, MatchCase:=False).Column
End Sub
Probably best not to use colIndex and rowIndex as variable names as they are already mentioned in the Excel Object Library.
SUBSTR(column, LENGTH(column) - 3, 4)
LENGTH
returns length of string and SUBSTR
returns 4 characters from "the position length - 4"
The right way is to execute npm update
. It's a really powerful command, it updates the missing packages and also checks if a newer version of package already installed can be used.
Read Intro to NPM to understand what you can do with npm.
Usage
git clone <repository>
Clone the repository located at the <repository> onto the local machine. The original repository can be located on the local filesystem or on a remote machine accessible via HTTP or SSH.
git clone <repo> <directory>
Clone the repository located at <repository> into the folder called <directory> on the local machine.

Below are the methods which have always worked for me
Set the display of the parent div to display: flex;
and the you can align the child elements inside the div using the justify-content: center;
(to align the items on main axis) and align-items: center;
(to align the items on cross axis).
If you have more than one child element and want to control the way they are arranged (column/rows), then you can also add flex-direction
property.
Working example:
.parent {_x000D_
align-items: center;_x000D_
border: 1px solid black;_x000D_
display: flex;_x000D_
justify-content: center;_x000D_
height: 250px;_x000D_
width: 250px;_x000D_
}_x000D_
_x000D_
.child {_x000D_
border: 1px solid black;_x000D_
height: 50px;_x000D_
width: 50px;_x000D_
}
_x000D_
<div class="parent">_x000D_
<div class="child"></div>_x000D_
</div>
_x000D_
2. (older method) Using position, margin properties and fixed size
Working example:
.parent {_x000D_
border: 1px solid black;_x000D_
height: 250px;_x000D_
position: relative;_x000D_
width: 250px;_x000D_

try with:
tr:last-child td:last-child{
border:none;
/*any other style*/
}
this will only affect the very last td element in the table, assuming is the only one (else, you'll just have to identify your table). Though, is very general, and it will adapt to the last TD if you add more content to your table. So if it is a particular case
td:nth-child(5){
border:none;
}
should be enough.
If you don't want to include the full path, you can do
add_executable(main main.cpp)
target_link_libraries(main bingitup)
bingitup
is the same name you'd give a target if you create the static library in a CMake project:
add_library(bingitup STATIC bingitup.cpp)
CMake automatically adds the lib
to the front and the .a
at the end on Linux, and .lib
at the end on Windows.
If the library is external, you might want to add the path to the library using
link_directories(/path/to/libraries/)
This will also work:
<Hyperlink Command="{Binding RelativeSource={RelativeSource AncestorType=ItemsControl},
Path=DataContext.AllowItemCommand}" />
ListView
will inherit its DataContext
from Window
, so it's available at this point, too.
And since ListView
, just like similar controls (e. g. Gridview
, ListBox
, etc.), is a subclass of ItemsControl
, the Binding
for such controls will work perfectly.
String[] array = new String[items2.size()];
items2.toArray(array);
ls -d "$PWD/"*
This looks only in the current directory. It quotes "$PWD" in case it contains spaces.
If you call your event handler on markup, as you're doing now, you can't (x-browser). But if you bind the click event with jquery, it's possible the following way:
Markup:
<a href="#" id="link1" >click</a>
Javascript:
$(document).ready(function(){
$("#link1").click(clickWithEvent); //Bind the click event to the link
});
function clickWithEvent(evt){
myFunc('p1', 'p2', 'p3');
function myFunc(p1,p2,p3){ //Defined as local function, but has access to evt
alert(evt.type);
}
}
Since the event ob
When you have changes on your working copy, from command line do:
git stash
This will stash your changes and clear your status report
git pull
This will pull changes from upstream branch. Make sure it says fast-forward in the report. If it doesn't, you are probably doing an unintended merge
git stash pop
This will apply stashed changes back to working copy and remove the changes from stash unless you have conflicts. In the case of conflict, they will stay in stash so you can start over if needed.
if you need to see what is in your stash
git stash list
This was the tutorial I was looking for in this thread. It shows the way to open files in Visual Studio Code by writing code .
1.- Open the file
Bash
open ~/.bash_profile
Terminal OS
open ~/.zshrc
2.- Add in your file the :
code () { VSCODE_CWD="$PWD" open -n -b "com.microsoft.VSCode" --args $* ;}
3.- Reinicialize terminal and try in the folder you want to open
code .
4.- Then you can use it as shown in this comment: https://stackoverflow.com/a/41821250/10033560

In my case, I had to pool database for payment confirmation to come in and then update WPF
UI.
Mechanism that spins up all the processes:
public void Execute(object parameter)
{
try
{
var url = string.Format("{0}New?transactionReference={1}", Settings.Default.PaymentUrlWebsite, "transactionRef");
Process.Start(new ProcessStartInfo(url));
ViewModel.UpdateUiWhenDoneWithPayment = new BackgroundWorker {WorkerSupportsCancellation = true};
ViewModel.UpdateUiWhenDoneWithPayment.DoWork += ViewModel.updateUiWhenDoneWithPayment_DoWork;
ViewModel.UpdateUiWhenDoneWithPayment.RunWorkerCompleted += ViewModel.updateUiWhenDoneWithPayment_RunWorkerCompleted;
ViewModel.UpdateUiWhenDoneWithPayment.RunWorkerAsync();
}
catch (Exception e)
{
ViewModel.Log.Error("Failed to navigate to payments", e);
MessageBox.Show("Failed to navigate to payments");
}
}
Mechanism that does checking for completion:
private void updateUiWhenDoneWithPayment_DoWork(object sender, DoWorkEventArgs e)
{
Thread.Sleep(30000);
while (string.IsNullOrEmpty(GetAuthToken()) && !((BackgroundWorker)sender).CancellationPending)
{
Thread.Sleep(5000);
}
//Plug in pooling mechanism
this.AuthCode = GetAuthToken();
}
Mechanism that cancels if window gets closed:
private void PaymentView_OnUnloaded(object sender, RoutedEventArgs e)
{
var context = DataContext as PaymentViewModel;
if (context.UpdateUiWhenDoneWithPayment != null && context.UpdateUiWhenDoneWithPayment.WorkerSupportsCancellation && context.UpdateUiWhenDoneWithPayment.IsBusy)
context.UpdateUiWhenDoneWithPayment.CancelAsync();

what is a base image?
A set of files, plus EXPOSE
'd ports, ENTRYPOINT
and CMD
.
You can add files and build a new image based on that base image, with a new Dockerfile
starting with a FROM
directive: the image mentioned after FROM
is "the base image" for your new image.
does it mean that if I declare
neo4j/neo4j
in aFROM
directive, that when my image is run the neo database will automatically run and be available within the container on port 7474?
Only if you don't overwrite CMD
and ENTRYPOINT
.
But the image in itself is enough: you would use a FROM neo4j/neo4j
if you had to add files related to neo4j
for your particular usage of neo4j
.
You could try doing it through R:
For Stata <= 15 you can use the haven package to read the dataset and then you simply write it to external CSV file:
library(haven)
yourData = read_dta("path/to/file")
write.csv(yourData, file = "yourStataFile.csv")
Alternatively, visit the link pointed by huntaub in a comment below.
For Stata <= 12 datasets foreign package can also be used
library(foreign)
yourData <- read.dta("yourStataFile.dta")
You'll need to order by the same field you're ordering by now, but descending.
As an example, if you have a time stamp when the upload was done called upload_time
, you'd do something like this;
For Pre-Laravel 4
return DB::table('files')->order_by('upload_time', 'desc')->first();
For Laravel 4 and onwards
return DB::table('files')->orderBy('upload_time', 'desc')->first();
For Laravel 5.7 and onwards
return DB::table('files')->latest('upload_time')->first();
This will order the rows in the files table by upload time, descending order, and take the first one. This will be the latest uploaded file.
I have also encountered this same error, despite all the provided solutions for the following reasons:
Swift 2.0: : Using UILabel Extension
Make constant enum values in a empty Swift file.
// AppRef.swift
import UIKit
import Foundation
enum UILabelTextPositions : String {
case VERTICAL_ALIGNMENT_TOP = "VerticalAlignmentTop"
case VERTICAL_ALIGNMENT_MIDDLE = "VerticalAlignmentMiddle"
case VERTICAL_ALIGNMENT_BOTTOM = "VerticalAlignmentBottom"
}
Using UILabel Extension:
Make a empty Swift class and name it. Add the following.
// AppExtensions.swift
import Foundation
import UIKit
extension UILabel{
func makeLabelTextPosition (sampleLabel :UILabel?, positionIdentifier : String) -> UILabel
{
let rect = sampleLabel!.textRectForBounds(bounds, limitedToNumberOfLines: 0)
switch positionIdentifier
{
case "VerticalAlignmentTop":
sampleLabel!.frame = CGRectMake(bounds.origin.x+5, bounds.origin.y, rect.size.width, rect.size.height)
break;
case "VerticalAlignmentMiddle":
sampleLabel!.frame = CGRectMake(bounds.origin.x+5,bounds.origin.y + (bounds.size.height - rect.size.height) / 2,
rect.size.width, rect.size.height);
break;
case "VerticalAlignmentBottom":
sampleLabel!.frame = CGRectMake(bounds.origin.x+5, bounds.origin.y + (bounds.size.height - rect.size.height),rect.size.width, rect.size.height);
break;
default:
sampleLabel!.frame = bounds;
break;
}
return sampleLabel!
}
}
Usage :
myMessageLabel.makeLabelTextPosition(messageLabel, positionIdentifier: UILabelTextPositions.VERTICAL_ALIGNMENT_TOP.rawValue)
The first parameter is not checkbox value but rather view model binding for the checkbox hence:
@Html.CheckBoxFor(m => m.SomeBooleanProperty, new { @checked = "checked" });
The first parameter must identify a boolean property within your model (it's an Expression not an anonymous method returning a value) and second property defines any additional HTML element attributes. I'm not 100% sure that the above attribute will initially check your checkbox, but you can try. But beware. Even though it may work you may have issues later on, when loading a valid model data and that particular property is set to false
.
Although my proper suggestion would be to provide initialized model to your view with that particular boolean property initialized to true
.
As per Asp.net MVC HtmlHelper
extension methods and inner working, checkboxes need to bind to boolean values and not integers what seems that you'd like to do. In that case a hidden field could store the id
.
There are of course other helper methods that you can use to get greater flexibility about checkbox values and behaviour:
@Html.CheckBox("templateId", new { value = item.TemplateID, @checked = true });
Note:
checked
is an HTML element boolean property and not a value attribute which means that you can assign any value to it. The correct HTML syntax doesn't include any assignments, but there's no way of providing an anonymous C# object with undefined property that would render as an HTML element property.
Very simple searching using pkgutil.iter_modules
from pkgutil import iter_modules
a=iter_modules()
while True:
try: x=a.next()
except: break
if 'searchstr' in x[1]: print x[1]
When you want to discard changes in your local branch, you can stash these changes using git stash command.
git stash save "some_name"
Your changes will be saved and you can retrieve those later,if you want or you can delete it. After doing this, your branch will not have any uncommitted code and you can pull the latest code from your main branch using git pull.
Expanding on Danny's Solution, but with all sorts of ways to report ages for younger folk (note, today is datetime.date(2015,7,17)
):
def calculate_age(born):
'''
Converts a date of birth (dob) datetime object to years, always rounding down.
When the age is 80 years or more, just report that the age is 80 years or more.
When the age is less than 12 years, rounds down to the nearest half year.
When the age is less than 2 years, reports age in months, rounded down.
When the age is less than 6 months, reports the age in weeks, rounded down.
When the age is less than 2 weeks, reports the age in days.
'''
today = datetime.date.today()
age_in_years = today.year - born.year - ((today.month, today.day) < (born.month, born.day))
months = (today.month - born.month - (today.day < born.day)) %12
age = today - born
age_in_days = age.days
if age_in_years >= 80:
return 80, 'years or older'
if age_in_years >= 12:
return age_in_years, 'years'
elif age_in_years >= 2:
half = 'and a half ' if months > 6 else ''
return age_in_years, '%syears'%half
elif months >= 6:
return months, 'months'
elif age_in_days >= 14:
return age_in_days/7, 'weeks'
else:
return age_in_days, 'days'
Sample code:
print '%d %s' %calculate_age(datetime.date(1933,6,12)) # >=80 years
print '%d %s' %calculate_age(datetime.date(1963,6,12)) # >=12 years
print '%d %s' %calculate_age(datetime.date(2010,6,19)) # >=2 years
print '%d %s' %calculate_age(datetime.date(2010,11,19)) # >=2 years with half
print '%d %s' %calculate_age(datetime.date(2014,11,19)) # >=6 months
print '%d %s' %calculate_age(datetime.date(2015,6,4)) # >=2 weeks
print '%d %s' %calculate_age(datetime.date(2015,7,11)) # days old

You can use Runtime.getRuntime().addShutdownHook(...)

I agree with the image in absolute div with 100% width and height. Make sure you set 100% width and height for the body in the CSS and set margins and padding to zero. Another issue you will find with this method is that when selecting text, the selection area can sometimes encompass the background image, which has the unfortunate effect of making the full page have the selected state. You can get round this by using the user-select:none
CSS rule, like so:
<html>
<head>
<style type="text/css">
html,body {
height: 100%;
width: 100%
margin: none;
padding: none;
}
#background {
width: 100%;
height: 100%;
position: fixed;
left: 0px;
top: 0px;
z-index: -99999;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-o-user-select: none;
user-select: none;
}
#background img {
width: 100%;
height: 100%;
}
#main{ z-index:10;}
</style>
</head>
<body>
<div id="main">
content here
</div>
<div id="background"><img src="bg.jpg"></div>
</body>
</html>
Again, Internet Explorer is the bad guy here, because it doesn't recognise the user-select option - not even Internet Explorer 10 preview supports it, so you have the option of either using JavaScript to prevent background image selection (for example, http://www.felgall.com/jstip35.htm ) or using CSS 3 background-stretch method.
Also, for SEO I would put the background image at the bottom of the page, but if the background image takes too long to load (that is, with a white background initially), you could move to the top of the page.
You could make a method:
public byte[] toBytes(char[] data) {
byte[] toRet = new byte[data.length];
for(int i = 0; i < toRet.length; i++) {
toRet[i] = (byte) data[i];
}
return toRet;
}
Hope this helps
Suppose for example your date is coming like this & you need to install momentjs for advance date features.
let cmpDate = Thu Aug 27 2020 00:00:00 GMT+0530 (India Standard Time)
let format = "MM/DD/YYYY";
let startDate: any = moment().format(format);
let endDate: any = moment().add(30, "days").format(format);
let compareDate: any = moment(cmpDate).format(format);
var startDate1 = startDate.split("/");
var startDate2 = endDate.split("/");
var compareDate1 = compareDate.split("/");
var fromDate = new Date(startDate1[2], parseInt(startDate1[1]) - 1, startDate1[0]);
var toDate = new Date(startDate2[2], parseInt(startDate2[1]) - 1, startDate2[0]);
var checkDate = new Date(compareDate1[2], parseInt(compareDate1[1]) - 1, compareDate1[0]);
if (checkDate > fromDate && checkDate < toDate) {
... condition works between current date to next 30 days
}
Wow. I'm unsure why this was so hard. I found I was unable to use any of the code samples above because I was using log4j2 over slf4j. This is my solution:
public class SpecialLogServiceTest {
@Mock
private Appender appender;
@Captor
private ArgumentCaptor<LogEvent> captor;
@InjectMocks
private SpecialLogService specialLogService;
private LoggerConfig loggerConfig;
@Before
public void setUp() {
// prepare the appender so Log4j likes it
when(appender.getName()).thenReturn("MockAppender");
when(appender.isStarted()).thenReturn(true);
when(appender.isStopped()).thenReturn(false);
final LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
final Configuration config = ctx.getConfiguration();
loggerConfig = config.getLoggerConfig("org.example.SpecialLogService");
loggerConfig.addAppender(appender, AuditLogCRUDService.LEVEL_AUDIT, null);
}
@After
public void tearDown() {
loggerConfig.removeAppender("MockAppender");
}
@Test
public void writeLog_shouldCreateCorrectLogMessage() throws Exception {
SpecialLog specialLog = new SpecialLogBuilder().build();
String expectedLog = "this is my log message";
specialLogService.writeLog(specialLog);
verify(appender).append(captor.capture());
assertThat(captor.getAllValues().size(), is(1));
assertThat(captor.getAllValues().get(0).getMessage().toString(), is(expectedLog));
}
}
The string is a .NET string so you can use .NET methods. In your case:
$index = "The string".IndexOf(" ")
will return 3, which is the first occurrence of space in the string. For more information see: http://msdn.microsoft.com/en-us/library/system.string.aspx
For your need try something like:
$s.SubString($s.IndexOf("_") + 1, $s.LastIndexOf(".") - $s.IndexOf("_") - 1)
Or you could use regexps:
if ($s -Match '(_)(.*)(\.)[^.]*$') { $matches[2] }
(has to be adjusted depending on exactly what you need).
You can use the gcc compiler in linux to link two c file in one output. Suppose you have two c files one is 'main.c' and another is 'support.c'. So the command to link these two is
gcc main.c support.c -o main.out
By this two files will be linked to a single output main.out To run the output the command will be
./main.out
If you are using function in main.c which is declared in support.c file then you should declare it in main also using extern storage class.
I have learned it is also possible to do this with the exec-maven-plugin if you're doing a "standalone" java app.

You will need to get a DateTime
object from your TimeSpan
and then you can format it easily.
One possible solution is adding the timespan to any date with zero time value.
var timespan = new TimeSpan(3, 0, 0);
var output = new DateTime().Add(timespan).ToString("hh:mm tt");
The output value will be "03:00 AM"
(for english locale).
They're equivalent. The access is the same.
The import is just a convention to save you from having to type the fully-resolved class name each time. You can write all your Java without using import, as long as you're a fast touch typer.
But there's no difference in efficiency or class loading.
POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObject functionalities like
Here is a good start for this
You can also generate POCOs so easily from your existing Entity framework project using Code generators.

Passing parameter suppress=True
to function set_printoptions
works only for numbers that fit in the default 8 character space allotted to it, like this:
import numpy as np
np.set_printoptions(suppress=True) #prevent numpy exponential
#notation on print, default False
# tiny med large
a = np.array([1.01e-5, 22, 1.2345678e7]) #notice how index 2 is 8
#digits wide
print(a) #prints [ 0.0000101 22. 12345678. ]
However if you pass in a number greater than 8 characters wide, exponential notation is imposed again, like this:
np.set_printoptions(suppress=True)
a = np.array([1.01e-5, 22, 1.2345678e10]) #notice how index 2 is 10
#digits wide, too wide!
#exponential notation where we've told it not to!
print(a) #prints [1.01000000e-005 2.20000000e+001 1.23456780e+10]
numpy has a choice between chopping your number in half thus misrepresenting it, or forcing exponential notation, it chooses the latter.
Here comes set_printoptions(formatter=...)
to the rescue to specify options for printing and rounding. Tell set_printoptions
to just print bare a bare float:
np.set_printoptions(suppress=True,
formatter={'float_kind':'{:f}'.format})
a = np.array([1.01e-5, 22, 1.2345678e30]) #notice how index 2 is 30
#digits wide.
#Ok good, no exponential notation in the large numbers:
print(a) #prints [0.000010 22.000000 1234567799999999979944197226496.000000]
We've force-suppressed the exponential notation, but it is not rounded or justified, so specify extra formatting options:
np.set_printoptions(suppress=True,
formatter={'float_kind':'{:0.2f}'.format}) #float, 2 units
#precision right, 0 on left
a = np.array([1.01e-5, 22, 1.2345678e30]) #notice how index 2 is 30
#digits wide
print(a) #prints [0.00 22.00 1234567799999999979944197226496.00]
The drawback for force-suppressing all exponential notion in ndarrays is that if your ndarray gets a huge float value near infinity in it, and you print it, you're going to get blasted in the face with a page full of numbers.

Notice that rounding is consistent at 2 units precision, and exponential notation is suppressed in both the very large e+x
and very small e-x
ranges.
You would need to enclose the pattern in a delimiter - typically a slash (/) is used. Try this:
echo preg_replace("/[^0-9]/","",'604-619-5135');
The same can be applied to a scenario where the data has been normalized, but now you want a table to have values found in a third table. The following will allow you to update a table with information from a third table that is liked by a second table.
UPDATE t1
LEFT JOIN
t2
ON
t2.some_id = t1.some_id
LEFT JOIN
t3
ON
t2.t3_id = t3.id
SET
t1.new_column = t3.column;
This would be useful in a case where you had users and groups, and you wanted a user to be able to add their own variation of the group name, so originally you would want to import the existing group names into the field where the user is going to be able to modify it.
$8.3.5/8 states-
"Functions shall not have a return type of type array or function, although they may have a return type of type pointer or reference to such things. There shall be no arrays of functions, although there can be arrays of pointers to functions."
int (&fn1(int (&arr)[5]))[5]{ // declare fn1 as returning refernce to array
return arr;

Approach 1: By extending WebApplicationException class
Create new exception by extending WebApplicationException
public class RestException extends WebApplicationException {
private static final long serialVersionUID = 1L;
public RestException(String message, Status status) {
super(Response.status(status).entity(message).type(MediaType.TEXT_PLAIN).build());
}
}
Now throw 'RestException' whenever required.
public static Employee getEmployee(int id) {
Employee emp = employees.get(id);
if (emp == null) {
throw new RestException("Employee with id " + id + " not exist", Status.NOT_FOUND);
}
return emp;
}
You can see complete application at this link.
Approach 2: Implement ExceptionMapper
Following mapper handles exception of type 'DataNotFoundException'
@Provider
public class DataNotFoundExceptionMapper implements
ExceptionMapper<DataNotFoundException> {
@Override
public Response toResponse(DataNotFoundException ex) {
ErrorMessage model = new ErrorMessage(ex.getErrorCode(),
ex.getMessage());
return Response.status(Status.NOT_FOUND).entity(model).build();
}
}
You can see complete application at this link.
For users of modern DataTables (1.10 and above), all the answers and examples on this page are for the old api, not the new. I had a very hard time finding a newer example but finally did find this DT forum post (TL;DR for most folks) which led me to this concise example.
The example code worked for me after I finally noticed the $() selector syntax immediately surrounding the html string. You have to add a node not a string.
That example really is worth looking at but, in the spirit of SO, if you just want to see a snippet of code that works:
var table = $('#example').DataTable();
table.rows.add( $(
'<tr>'+
' <td>Tiger Nixon</td>'+
' <td>System Architect</td>'+
' <td>Edinburgh</td>'+
' <td>61</td>'+
' <td>2011/04/25</td>'+
' <td>$3,120</td>'+
'</tr>'
) ).draw();
The careful reader might note that, since we are adding only one row of data, that table.row.add(...) should work as well and did for me.
$sql = "select count(column_name) as count from table";
Are you using sublime text on linux? I got the same problem and it was solved! Here is my c.sublime-build:
{
"shell_cmd" : "gcc $file_name -o $file_base_name && ./$file_base_name",
"selector" : "source.c",
"shell":true,
"working_dir" : "$file_path"
}
Here's the MooTools version of Jason's. Fixes it in Safari too.
window.addEvent('domready',function() {
$('username').focus();
if ((navigator.userAgent.toLowerCase().indexOf(\"chrome\") >= 0)||(navigator.userAgent.toLowerCase().indexOf(\"safari\") >= 0))
{
var _interval = window.setInterval(function ()
{
var autofills = $$('input:-webkit-autofill');
if (autofills.length > 0)
{
window.clearInterval(_interval); // stop polling
autofills.each(function(el)
{
var clone = el.clone(true,true).inject(el,'after');;
el.dispose();
});
}
}, 20);
}
});
Based on the question, I believe some assumptions / requirements for this function include:
"foo:bar[0]"
should return a cookie (literally) named "foo:bar[0]";Under these assumptions, it's clear that encodeURIComponent
/ decodeURIComponent
should not be used; doing so assumes that the code that set the cookie also encoded it using these functions.
The regular expression approach gets problematic if the cookie name can contain special characters. jQuery.cookie works around this issue by encoding the cookie name (actually both name and value) when storing a cookie, and decoding the name when retrieving a cookie. A regular expression solution is below.
Unless you're only reading cookies you control completely, it would also be advisable to read cookies from document.cookie
directly and not cache the results, since there is no way to know if the cache is invalid without reading document.cookie
again.
(While accessing and parsing document.cookies
will be slightly slower than using a cache, it would not be as slow as reading other parts of the DOM, since cookies do not play a role in the DOM / render trees.)
Here goes the Code Golf answer, based on PPK's (loop-based) function:
function readCookie(name) {
name += '=';
for (var ca = document.cookie.split(/;\s*/), i = ca.length - 1; i >= 0; i--)
if (!ca[i].indexOf(name))
return ca[i].replace(name, '');
}
which when minified, comes to 128 characters (not counting the function name):
function readCookie(n){n+='=';for(var a=document.cookie.split(/;\s*/),i=a.length-1;i>=0;i--)if(!a[i].indexOf(n))return a[i].replace(n,'');}
Update: If you really want a regular expression solution:
function readCookie(name) {
return (name = new RegExp('(?:^|;\\s*)' + ('' + name).replace(/[-[\]{}()*+?.,\\^$|#\s]/g, '\\$&') + '=([^;]*)').exec(document.cookie)) && name[1];
}
This escapes any special characters in the cookie name before constructing the RegExp object. Minified, this comes to 134 characters (not counting the function name):
function readCookie(n){return(n=new RegExp('(?:^|;\\s*)'+(''+n).replace(/[-[\]{}()*+?.,\\^$|#\s]/g,'\\$&')+'=([^;]*)').exec(document.cookie))&&n[1];}
As Rudu and cwolves have pointed out in the comments, the regular-expression-escaping regex can be shortened by a few characters. I think it would be good to keep the escaping regex consistent (you may be using it elsewhere), but their suggestions are worth considering.
Both of these functions won't handle null
or undefined
, i.e. if there is a cookie named "null", readCookie(null)
will return its value. If you need to handle this case, adapt the code accordingly.
So that you don't mess up other permissions already on the file, use the flag +
, such as via
sudo chmod -R o+rw /var/www
The answer of your question is that you must set the same value in Primary and secondary key. Thanks
I had some problems with the insertion process just like you, so here is the code how I have solved the problem:
void add_by_position(int data, int pos)
{
link *node = new link;
link *linker = head;
node->data = data;
for (int i = 0; i < pos; i++){
linker = linker->next;
}
node->next = linker;
linker = head;
for (int i = 0; i < pos - 1; i++){
linker = linker->next;
}
linker->next = node;
boundaries++;
}
From the use of 8080 I'm assuming you are using a tomcat servlet container to serve your rest api. If this is the case you can also consider to have your webserver proxy the requests to the servlet container.
With apache you would typically use mod_jk (although there are other alternatives) to serve the api trough the web server behind port 80 instead of 8080 which would solve the cross domain issue.
This is common practice, have the 'static' content in the webserver and dynamic content in the container, but both served from behind the same domain.
The url for the rest api would be http://localhost/restws/json/product/get
Here a description on how to use mod_jk to connect apache to tomcat: http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html
Another way, for variety. Although this is somewhat less flexible than the others. Unfortunately, the graphs appear one above the other, rather than side-by-side, which you did request in your original question. But it is very concise.
df.plot(subplots=True)
If the dataframe has more than the two series, and you only want to plot those two, you'll need to replace df
with df[['korisnika','osiguranika']]
.
You can use .change()
function too
E.g.:
$('form input[type=checkbox]').change(function() { console.log('hello') });
I had the same issue on OS X 10.9.1 with python 2.7.5. No issues with WORKON_HOME
for me, but I did have to manually add source "/usr/local/bin/virtualenvwrapper.sh"
to ~/.bash_profile
(or ~/.bashrc
in unix) after I ran pip install virtualenvwrapper
This is ridiculous but I just have rebooted my machine (mac) and the problem was gone like it has never happened. I hate to sound like a support guy...
Why does it implement its methods? How can it implement its methods when an interface can't contain method body? How can it implement the methods when it extends the other interface and not implement it? What is the purpose of an interface implementing another interface?
Interface does not implement the methods of another interface but just extends them.
One example where the interface extension is needed is: consider that you have a vehicle interface with two methods moveForward
and moveBack
but also you need to incorporate the Aircraft which is a vehicle but with some addition methods like moveUp
, moveDown
so
in the end you have:
public interface IVehicle {
bool moveForward(int x);
bool moveBack(int x);
};
and airplane:
public interface IAirplane extends IVehicle {
bool moveDown(int x);
bool moveUp(int x);
};
I just queried my database with millions of customers in the USA.
The maximum first name length was 46. I go with 50. (Of course, only 500 of those were over 25, and they were all cases where data imports resulted in extra junk winding up in that field.)
Last name was similar to first name.
Email addresses maxed out at 62 characters. Most of the longer ones were actually lists of email addresses separated by semicolons.
Street address maxes out at 95 characters. The long ones were all valid.
Max city length was 35.
This should be a decent statistical spread for people in the US. If you have localization to consider, the numbers could vary significantly.
The best I've seen explaining this with examples, diagrams, and even a 'try it yourself' view is here.
The diagram below I think gives an instant visual understanding of the difference.
One thing to keep in mind is standards compliant browsers (IE quirks is an exception) render only the content portion to the given width, so keep track of this in layout calculations. Also note that border box is seeing somewhat of a comeback with Bootstrap 3 supporting it.
Your adb connection is broken.

If you are using Java 7, Files (in the standard library) is the best approach:
/* You can get Path from file also: file.toPath() */
Files.copy(InputStream in, Path target)
Files.copy(Path source, OutputStream out)
Edit: Of course it's just useful when you create one of InputStream or OutputStream from file. Use file.toPath()
to get path from file.
To write into an existing file (e.g. one created with File.createTempFile()
), you'll need to pass the REPLACE_EXISTING
copy option (otherwise FileAlreadyExistsException
is thrown):
Files.copy(in, target, StandardCopyOption.REPLACE_EXISTING)
You can also .pop
off the last element. Be careful, this will change the value of the array, but that might be OK for you.
var a = [1,2,3];
a.pop(); // 3
a // [1,2]
To remove all OIDs from your database tables, you can use this Linux script:
First, login as PostgreSQL superuser:
sudo su postgres
Now run this script, changing YOUR_DATABASE_NAME with you database name:
for tbl in `psql -qAt -c "select schemaname || '.' || tablename from pg_tables WHERE schemaname <> 'pg_catalog' AND schemaname <> 'information_schema';" YOUR_DATABASE_NAME` ; do psql -c "alter table $tbl SET WITHOUT OIDS" YOUR_DATABASE_NAME ; done
I used this script to remove all my OIDs, since Npgsql 3.0 doesn't work with this, and it isn't important to PostgreSQL anymore.
A different case in which I encountered this was when I was using echo
to pipe the JSON into my python script and carelessly wrapped the JSON string in double quotes:
echo "{"thumbnailWidth": 640}" | myscript.py
Note that the JSON string itself has quotes and I should have done:
echo '{"thumbnailWidth": 640}' | myscript.py
As it was, this is what the python script received: {thumbnailWidth: 640}
; the double quotes were effectively stripped.

If you don't specify a special network bridge, all of them will use the same default one.
You were probably changing the layout margin after it has been drawn. mOldTextView.invalidate() is useless. you needed to call requestLayout() on the parent to relayout the new configuration. When you moved the layout changing code before the drawing took place, everything worked fine.
This is the safest solution:
git stash
Now you can do whatever you want without fear of conflicts.
For instance:
git checkout origin/master
If you want to include the remote changes in the master branch you can do:
git reset --hard origin/master
This will make you branch "master" to point to "origin/master".
create or replace PROCEDURE PROC_USER_EXP

END IF;

The min sdk version is the minimum version of the Android operating system required to run your application.
The target sdk version is the version of Android that your app was created to run on.
The compile sdk version is the the version of Android that the build tools uses to compile and build the application in order to release, run, or debug.
Usually the compile sdk version and the target sdk version are the same.
Just a small update to Zisha's answer.
In my project all the modules were placed in a folder called "modules" and all the components are placed in "components" folder under "src/app"
so to create a component under a specific path, I used the following syntax :
ng g c components_path/component_name --module modules_path/module_name
example :
ng g c components/login --module modules/app
I made some changes in above code to look for a location fix by both GPS and Network for about 5sec and give me the best known location out of it.
public class LocationService implements LocationListener {

} else if (isNewer && !isLessAccurate) {
return true;
} else if (isNewer && !isSignificantlyLessAccurate
&& isFromSameProvider) {
return true;
}
return false;
}
}
In the above class, I am registering a location listener for both GPS and network, so an onLocationChanged
call back can be called by either or both of them multiple times and we just compare the new location fix with the one we already have and keep the best one.
Different people who come to this question mean different things by a popup box. I highly recommend reading the Temporary Views documentation. My answer is largely a summary of this and other related documentation.
Alerts display a title and an optional message. The user must acknowledge it (a one-button alert) or make a simple choice (a two-button alert) before going on. You create an alert with a UIAlertController
.
It is worth quoting the documentation's warning and advice about creating unnecessary alerts.
Notes:
UIAlertView
was deprecated. You should use UIAlertController
to create alerts now.Action Sheets give the user a list of choices. They appear either at the bottom of the screen or in a popover depending on the size and orientation of the device. As with alerts, a UIAlertController
is used to make an action sheet. Before iOS 8, UIActionSheet
was used, but now the documentation says:
Important:
UIActionSheet
is deprecated in iOS 8. (Note thatUIActionSheetDelegate
is also deprecated.) To create and manage action sheets in iOS 8 and later, instead useUIAlertController
with apreferredStyle
ofUIAlertControllerStyleActionSheet
.
A modal view is a self-contained view that has everything it needs to complete a task. It may or may not take up the full screen. To create a modal view, use a UIPresentationController
with one of the Modal Presentation Styles.
See also
A Popover is a view that appears when a user taps on something and disappears when tapping off it. It has an arrow showing the control or location from where the tap was made. The content can be just about anything you can put in a View Controller. You make a popover with a UIPopoverPresentationController
. (Before iOS 8, UIPopoverController
was the recommended method.)
In the past popovers were only available on the iPad, but starting with iOS 8 you can also get them on an iPhone (see here, here, and here).

Notifications are sounds/vibrations, alerts/banners, or badges that notify the user of something even when the app is not running in the foreground.

In Android, a Toast is a short message that displays on the screen for a short amount of time and then disappears automatically without disrupting user interaction with the app.
People coming from an Android background want to know what the iOS version of a Toast is. Some examples of these questions can he found here, here, here, and here. The answer is that there is no equivalent to a Toast in iOS. Various workarounds that have been presented include:
UIView
However, my advice is to stick with the standard UI options that already come with iOS. Don't try to make your app look and behave exactly the same as the Android version. Think about how to repackage it so that it looks and feels like an iOS app.

If you are making jquery ajax request, dont forget to add
contentType:'application/json'
Integer i = 5; //example
Long l = Long.valueOf(i.longValue());
This avoids the performance hit of converting to a String. The longValue()
method in Integer is just a cast of the int value. The Long.valueOf()
method gives the vm a chance to use a cached value.
One possible issue is that your new class has a different Target or different Targets from the other one.
For example, it might have a testing target while the other one doesn't. For this specific case, you have to include all of your classes in the testing target or none of them.
If you would like to work with a textbox, be aware that setting the TextMode property to "Date" will not work on Internet Explorer 11, because it does not currently support the "Date", "DateTime", nor "Time" values.
This example illustrates how to implement it using a textbox, including validation of the dates (since the user could enter just numbers). It will work on Internet Explorer 11 as well other web browsers.

if (True):
print [f for f in [1, 2, 3]]
main()
Python 2.7.6 returns an error:
Traceback (most recent call last):
File "weird.py", line 9, in <module>
main()
File "weird.py", line 5, in main
print f(3)
UnboundLocalError: local variable 'f' referenced before assignment
Python sees the f
is used as a local variable in [f for f in [1, 2, 3]]
, and decides that it is also a local variable in f(3)
. You could add a global f
statement:
def f(x):
return x
def main():
global f
print f(3)
if (True):
print [f for f in [1, 2, 3]]
main()
It does work; however, f becomes 3 at the end... That is, print [f for f in [1, 2, 3]]
now changes the global variable f
to 3
, so it is not a function any more.
Fortunately, it works fine in Python3 after adding the parentheses to print
.
After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.
It's incorrect to use zeros in date or in datetime, just put null instead of zeros.
Try like
<script>
function Data(string)
{
$('.filter').removeClass('active');
$(this).parent('.filter').addClass('active') ;
}
</script>
For the class selector you need to use .
before the classname.And you need to add the class for the parent. Bec you are clicking on anchor tag not the filter
.
You should also use the style 'color' and not 'font-color'
<?php
foreach($months as $key => $month){
if(strpos($filename,$month)!==false){
echo "<style = 'color: #ff0000;'> Movie List for {$key} 2013 </style>";
}
}
?>
In general, the comments on double and single quotes are correct in other suggestions. $Variables only execute in double quotes.
Since the Fetch API is supported by Chrome (and most other browsers), it is now quite easy to make HTTP requests from the devtools console.
To GET a JSON file for instance:
fetch('https://jsonplaceholder.typicode.com/posts/1')_x000D_
.then(res => res.json())_x000D_
.then(console.log)
_x000D_
Or to POST a new resource:
fetch('https://jsonplaceholder.typicode.com/posts', {_x000D_
method: 'POST',_x000D_
body: JSON.stringify({_x000D_
title: 'foo',_x000D_
body: 'bar',_x000D_
userId: 1_x000D_
}),_x000D_
headers: {_x000D_
'Content-type': 'application/json; charset=UTF-8'_x000D_
}_x000D_
})_x000D_
.then(res => res.json())_x000D_
.then(console.log)
_x000D_
Chrome Devtools actually also support new async/await syntax (even though await normally only can be used within an async function):
const response = await fetch('https://jsonplaceholder.typicode.com/posts/1')
console.log(await response.json())
Notice that your requests will be subject to the same-origin policy, just like any other HTTP-request in the browser, so either avoid cross-origin requests, or make sure the server sets CORS-headers that allow your request.
Using a plugin (old answer)
As an addition to previously posted suggestions I've found the Postman plugin for Chrome to work very well. It allow you to set headers and URL parameters, use HTTP authentication, save request you execute frequently and so on.
var arrLength = arr.length;
if(arrLength > maxNumber){
arr.splice( 0, arrLength - maxNumber);
}
This soultion works better in an dynamic environment like p5js. I put this inside the draw call and it clamps the length of the array dynamically.
The problem with:
arr.slice(0,5)
...is that it only takes a fixed number of items off the array per draw frame, which won't be able to keep the array size constant if your user can add multiple items.
The problem with:
if (arr.length > 4) arr.length = 4;
...is that it takes items off the end of the array, so which won't cycle through the array if you are also adding to the end with push().
You can put the condition after the WHEN
clause, like so:
SELECT
CASE
WHEN PAT_ENT.SCR_DT is not null and PAT_ENTRY.ELIGIBILITY is null THEN 'Favor'
WHEN PAT_ENT.SCR_DT is not null and PAT_ENTRY.EL = 'No' THEN 'Error'
WHEN PAT_ENTRY.EL = 'Yes' and ISNULL(DS.DES, 'OFF') = 'OFF' THEN 'Active'
WHEN DS.DES = 'N' THEN 'Early Term'
WHEN DS.DES = 'Y' THEN 'Complete'
END
FROM
....
Of course, the argument could be made that complex rules like this belong in your business logic layer, not in a stored procedure in the database...
There is a confusion that is causing a lot of TortoiseSVN users to use the wrong command line tools when they actually were looking for svn.exe
command line client.
What should I do or can't TortoiseSVN be used from the command line?
If you want to run Subversion commands from the command prompt, you should run the svn.exe
command line client. TortoiseSVN 1.6.x and older versions did not include SVN command-line tools, but modern versions do.
If you want to get SVN command line tools without having to install TortoiseSVN, check the SVN binary distributions page or simply download the latest version from VisualSVN downloads page.
If you have SVN command line tools installed on your system, but still get the error 'svn' is not recognized as an internal or external command
, you should check %PATH%
environment variable. %PATH%
must include the path to SVN tools directory e.g. C:\Program Files (x86)\VisualSVN\bin
.
Apart from svn.exe
, TortoiseSVN comes with TortoiseProc.exe
that can be called from command prompt. In most cases, you do not need to use this tool, because it should be only used for GUI automation. TortoiseProc.exe
is not a replacement for SVN command-line client.
If you want to round to the nearest int:
int rounded = (int)Math.Round(precise, 0);
You can also use:
int rounded = Convert.ToInt32(precise);
Which will use Math.Round(x, 0);
to round and cast for you. It looks neater but is slightly less clear IMO.
If you want to round up:
int roundedUp = (int)Math.Ceiling(precise);
Try this,
var arg = new { i = 123, j = 456 };
var task = new TaskFactory().StartNew(new Func<dynamic, int>((argument) =>
{
dynamic x = argument.i * argument.j;
return x;
}), arg, CancellationToken.None, TaskCreationOptions.AttachedToParent, TaskScheduler.Default);
task.Wait();
var result = task.Result;
[chr(i) for i in range(ord('a'),ord('z')+1)]
If you're putting a <meta> tag in your css files, you're doing something wrong. The <meta> tag belongs in your html files, and tells the browser how the html is encoded, it doesn't say anything about the css, which is a separate file. You could conceivably have completely different encodings for your html and css, although I can't imagine this would be a good idea.
You can also write a shell script file and invoke that file from the java code. as shown below
{
Process proc = Runtime.getRuntime().exec("./your_script.sh");
proc.waitFor();
}
Write the linux commands in the script file, once the execution is over you can read the diff file in Java.
The advantage with this approach is you can change the commands with out changing java code.
Actually, the HTML 4.01 spec says that these attributes do not require values. I haven't personally encountered a situation where providing a value rendered these controls as unselected.
Here are the respective links to the spec document for selected and checked.
Edit: Firebug renders the checkbox as checked regardless of any values I put in quotes for the checked attribute (including just typing "checked" with no values whatsoever), and IE 8's Developer Tools forces checked="checked". I'm not sure if any similar tools exist for other browsers that might alter the rendered state of a checkbox, however.
For ASP.NET MVC if you want to make an exception for leaving the page via submitting a particular form:
Set a form id:
@using (Html.BeginForm("Create", "MgtJob", FormMethod.Post, new { id = "createjob" }))
{
// Your code
}
<script type="text/javascript">
// Without submit form
$(window).bind('beforeunload', function () {
if ($('input').val() !== '') {
return "It looks like you have input you haven't submitted."
}
});
// this will call before submit; and it will unbind beforeunload
$(function () {
$("#createjob").submit(function (event) {
$(window).unbind("beforeunload");
});
});
</script>
If you have a method that you want to throw an error but you want to do some cleanup in your method beforehand you can put the code that will throw the exception inside a try block, then put the cleanup in the catch block, then throw the error.
try {
//Dangerous code: could throw an error
} catch (Exception e) {
//Cleanup: make sure that this methods variables and such are in the desired state
throw e;
}
This way the try/catch block is not actually handling the error but it gives you time to do stuff before the method terminates and still ensures that the error is passed on to the caller.
An example of this would be if a variable changed in the method then that variable was the cause of an error. It may be desirable to revert the variable.
You get the warning because you did not assign a value to one
, which is a pointer. This is undefined behavior.
You should declare it like this:
Vector* one = malloc(sizeof(Vector));
or like this:
Vector one;
in which case you need to replace ->
operator with .
like this:
one.a = 12;
one.b = 13;
one.c = -11;
Finally, in C99 and later you can use designated initializers:
Vector one = {
.a = 12
, .b = 13
, .c = -11
};
With option 2 in @agstudy's answer now deprecated, defining data with a function can be handy.
library(plyr)
ggplot(data=dat) +
geom_line(aes(Value1, Value2, group=ID, colour=ID),
data=function(x){x$ID %in% c("P1", "P3"))
This approach comes in handy if you wish to reuse a dataset in the same plot, e.g. you don't want to specify a new column in the data.frame, or you want to explicitly plot one dataset in a layer above the other.:
library(plyr)
ggplot(data=dat, aes(Value1, Value2, group=ID, colour=ID)) +
geom_line(data=function(x){x[!x$ID %in% c("P1", "P3"), ]}, alpha=0.5) +
geom_line(data=function(x){x[x$ID %in% c("P1", "P3"), ]})
For posterity, fish aliases are just functions:
$ alias foo="echo bar"
$ type foo
foo is a function with definition
function foo
echo bar $argv;
end
To remove it
$ unalias foo
/usr/bin/unalias: line 2: unalias: foo: not found
$ functions -e foo
$ type foo
type: Could not find “foo”
You want
round(new MathContext(0)); // or perhaps another math context with rounding mode HALF_UP

One caveat is to be careful with the credentials, pull them from a key store rather than hard-coded as illustrated here ... but that's a different topic.
Thanks, everyone, for your answers.
Better yet:
for i in xa*; do
sed -i 's/asd/dfg/g' $i
done
because nobody knows how many files are there, and it's easy to break command line limits.
Here's what happens when there are too many files:
# grep -c aaa *
-bash: /bin/grep: Argument list too long
# for i in *; do grep -c aaa $i; done

I'm always adding my own utils function, which looks like this.
function setPseudoElContent(selector, value) {
document.styleSheets[0].addRule(selector, 'content: "' + value + '";');
}
setPseudoElContent('.class::after', 'Hello World!');
or make use of ES6 Features:
const setPseudoElContent = (selector, value) => {
document.styleSheets[0].addRule(selector, `content: "${value}";`);
}
setPseudoElContent('.class::after', 'Hello World!');
In addition to some of the other answers, you could also access the HTML element via:
var htmlEl = document.body.parentNode;
Then you could get the inner HTML content:
var inner = htmlEl.innerHTML;
Doing so this way seems to be marginally faster. If you are just obtaining the HTML element, however, document.body.parentNode
seems to be quite a bit faster.
After you have the HTML element, you can mess with the attributes with the getAttribute
and setAttribute
methods.
For the DOCTYPE, you could use document.doctype
, which was elaborated upon in this question.
To disable inputting password:
sudo visudo
Then add a new line like below and save then:
# The user can run installer as root without inputting password
yourusername ALL=(root) NOPASSWD: /usr/sbin/installer
Then you run installer without password:
sudo installer -pkg ...
Use the format()
method for objects of class "yearmon"
. Here is your example date (properly created!)
date1 <- as.yearmon("Mar 2012", "%b %Y")
Then we can extract the date parts as required:
> format(date1, "%b") ## Month, char, abbreviated
[1] "Mar"
> format(date1, "%Y") ## Year with century
[1] "2012"
> format(date1, "%m") ## numeric month
[1] "03"
These are returned as characters. Where appropriate, wrap in as.numeric()
if you want the year or numeric month as a numeric variable, e.g.
> as.numeric(format(date1, "%m"))
[1] 3
> as.numeric(format(date1, "%Y"))
[1] 2012
See ?yearmon
and ?strftime
for details - the latter explains the placeholder characters you can use.
Here's what worked well for me:
find . -path '*/.svn' -prune -o -type f -exec gawk '/Dansk/{a=1}/Norsk/{b=1}/Svenska/{c=1}END{ if (a && b && c) print FILENAME }' {} \;
./path/to/file1.sh
./another/path/to/file2.txt
./blah/foo.php
If I just wanted to find .sh files with these three, then I could have used:
find . -path '*/.svn' -prune -o -type f -name "*.sh" -exec gawk '/Dansk/{a=1}/Norsk/{b=1}/Svenska/{c=1}END{ if (a && b && c) print FILENAME }' {} \;
./path/to/file1.sh
Ok found the answer. exchange()
is the best way. Oddly the HttpEntity
class doesn't have a setBody()
method (it has getBody()
), but it is still possible to set the request body, via the constructor.
// Create the request body as a MultiValueMap
MultiValueMap<String, String> body = new LinkedMultiValueMap<String, String>();
body.add("field", "value");
// Note the body object as first parameter!
HttpEntity<?> httpEntity = new HttpEntity<Object>(body, requestHeaders);
ResponseEntity<MyModel> response = restTemplate.exchange("/api/url", HttpMethod.POST, httpEntity, MyModel.class);
export
is used to set environment variables. For example:
export EDITOR=pico
Will set your default text editor to be the pico
command.
I know this has been answered, but here's mine just because I think case is an under-appreciated tool. (Maybe because people think it is slow, but it's at least as fast as an if, sometimes faster.)
case "$1" in
0|1) xinput set-prop 12 "Device Enabled" $1 ;;
*) echo "This script requires a 1 or 0 as first parameter." ;;
esac
... since dates naturally have time-zone information, which can span regions with different day light savings adjustments
Previous answers to this question don't account for cases where the two dates in question span a daylight saving time (DST) change. The date on which the DST change happens will have a duration in milliseconds which is != 1000*60*60*24
, so the typical calculation will fail.
You can work around this by first normalizing the two dates to UTC, and then calculating the difference between those two UTC dates.
Now, the solution can be written as,
const _MS_PER_DAY = 1000 * 60 * 60 * 24;
// a and b are javascript Date objects
function dateDiffInDays(a, b) {
// Discard the time and time-zone information.
const utc1 = Date.UTC(a.getFullYear(), a.getMonth(), a.getDate());
const utc2 = Date.UTC(b.getFullYear(), b.getMonth(), b.getDate());
return Math.floor((utc2 - utc1) / _MS_PER_DAY);
}
// test it
const a = new Date("2017-01-01"),
b = new Date("2017-07-25"),
difference = dateDiffInDays(a, b);
This works because UTC time never observes DST. See Does UTC observe daylight saving time?
p.s. After discussing some of the comments on this answer, once you've understood the issues with javascript dates that span a DST boundary, there is likely more than just one way to solve it. What I provided above is a simple (and tested) solution. I'd be interested to know if there is a simple arithmetic/math based solution instead of having to instantiate the two new Date objects. That could potentially be faster.
Great answer by F.Mörk. But if you want to update translation, or add new languages once the application is released, you're stuck, because you always have to recompile it to generate the resources.dll.
Here is a solution to manually compile a resource dll. It uses the resgen.exe and al.exe tools (installed with the sdk).
Say you have a Strings.fr.resx resource file, you can compile a resources dll with the following batch:
resgen.exe /compile Strings.fr.resx,WpfRibbonApplication1.Strings.fr.resources
Al.exe /t:lib /embed:WpfRibbonApplication1.Strings.fr.resources /culture:"fr" /out:"WpfRibbonApplication1.resources.dll"
del WpfRibbonApplication1.Strings.fr.resources
pause
Be sure to keep the original namespace in the file names (here "WpfRibbonApplication1")
Writing JSON Parser Class
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {}
public JSONObject getJSONFromUrl(String url) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}
Parsing JSON Data
Once you created parser class next thing is to know how to use that class. Below i am explaining how to parse the json (taken in this example) using the parser class.
2.1. Store all these node names in variables: In the contacts json we have items like name, email, address, gender and phone numbers. So first thing is to store all these node names in variables. Open your main activity class and declare store all node names in static variables.
// url to make request
private static String url = "http://api.9android.net/contacts";
// JSON Node names
private static final String TAG_CONTACTS = "contacts";
private static final String TAG_ID = "id";
private static final String TAG_NAME = "name";
private static final String TAG_EMAIL = "email";
private static final String TAG_ADDRESS = "address";
private static final String TAG_GENDER = "gender";
private static final String TAG_PHONE = "phone";
private static final String TAG_PHONE_MOBILE = "mobile";
private static final String TAG_PHONE_HOME = "home";
private static final String TAG_PHONE_OFFICE = "office";
// contacts JSONArray
JSONArray contacts = null;
2.2. Use parser class to get JSONObject
and looping through each json item. Below i am creating an instance of JSONParser
class and using for loop i am looping through each json item and finally storing each json data in variable.
// Creating JSON Parser instance
JSONParser jParser = new JSONParser();
// getting JSON string from URL
JSONObject json = jParser.getJSONFromUrl(url);
try {
// Getting Array of Contacts
contacts = json.getJSONArray(TAG_CONTACTS);
// looping through All Contacts
for(int i = 0; i < contacts.length(); i++){
JSONObject c = contacts.getJSONObject(i);
// Storing each json item in variable
String id = c.getString(TAG_ID);
String name = c.getString(TAG_NAME);
String email = c.getString(TAG_EMAIL);
String address = c.getString(TAG_ADDRESS);
String gender = c.getString(TAG_GENDER);
// Phone number is agin JSON Object
JSONObject phone = c.getJSONObject(TAG_PHONE);
String mobile = phone.getString(TAG_PHONE_MOBILE);
String home = phone.getString(TAG_PHONE_HOME);
String office = phone.getString(TAG_PHONE_OFFICE);
}
} catch (JSONException e) {
e.printStackTrace();
}
Top answers are saying mathlog10 faster but I got results that suggest len(str(n)) is faster.
arr = []
for i in range(5000000):
arr.append(random.randint(0,12345678901234567890))
%%timeit
for n in arr:
len(str(n))
//2.72 s ± 304 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
%%timeit
for n in arr:
int(math.log10(n))+1
//3.13 s ± 545 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
Besides, I haven't added logic to the math way to return accurate results and I can only imagine it slows it even more.
I have no idea how the previous answers proved the maths way is faster though.
