You have #include "fun.cpp"
in mainfile.cpp
so compiling with:
g++ -o hw1 mainfile.cpp
will work, however if you compile by linking these together like
g++ -g -std=c++11 -Wall -pedantic -c -o fun.o fun.cpp
g++ -g -std=c++11 -Wall -pedantic -c -o mainfile.o mainfile.cpp
As they mention above, adding #include "fun.hpp"
will need to be done or it won't work. However, your case with the funct()
function is slightly different than my problem.
I had this issue when doing a HW assignment and the autograder compiled by the lower bash recipe, yet locally it worked using the upper bash.
The creator of C++ says that isn't broking any encapsulation principle, and I will quote him:
Does "friend" violate encapsulation? No. It does not. "Friend" is an explicit mechanism for granting access, just like membership. You cannot (in a standard conforming program) grant yourself access to a class without modifying its source.
Is more than clear...
Hey! I'm the developer of wxMathPlot! The project is active: I just took a long time to get a new release, because the code needed a partial rewriting to introduce new features. Take a look to the new 0.1.0 release: it is a great improvement from old versions. Anyway, it doesn't provide 3D (even if I always thinking about it...).
Here is a secure version of Alex Martelli's:
import csv
with open('filename', 'wb') as myfile:
wr = csv.writer(myfile, quoting=csv.QUOTE_ALL)
wr.writerow(mylist)
We don't stop or kill a thread rather we do Thread.currentThread().isInterrupted().
public class Task1 implements Runnable {
public void run() {
while (!Thread.currentThread().isInterrupted()) {
................
................
................
................
}
}
}
in main we will do like this:
Thread t1 = new Thread(new Task1());
t1.start();
t1.interrupt();
I know it was not available at the time, but now you could also use Anaconda navigator to install a specific version of packages in the environments tab.
Not sure why you specify that it has to be within Angular. It's easily accomplished through JavaScript. Look at the navigator
object.
Just open up your console and inspect navigator
. It seems what you're specifically looking for is .userAgent
or .appVersion
.
I don't have IE9 installed, but you could try this following code
//Detect if IE 9
if(navigator.appVersion.indexOf("MSIE 9.")!=-1)
This is similar to PierreBdR
, without copying the map.
#include <map>
using namespace std;
bool create_map(map<int,int> &m)
{
m[1] = 2;
m[3] = 4;
m[5] = 6;
return true;
}
static map<int,int> m;
static bool _dummy = create_map (m);
This can be done through the youtube player API:
Working example:
<div id="player"></div>
<script src="http://www.youtube.com/player_api"></script>
<script>
// create youtube player
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {
width: '640',
height: '390',
videoId: '0Bmhjf0rKe8',
events: {
onReady: onPlayerReady,
onStateChange: onPlayerStateChange
}
});
}
// autoplay video
function onPlayerReady(event) {
event.target.playVideo();
}
// when video ends
function onPlayerStateChange(event) {
if(event.data === 0) {
alert('done');
}
}
</script>
prop.table is a nice friendly way of obtaining proportions of tables.
m <- matrix(1:4,2)
m
[,1] [,2]
[1,] 1 3
[2,] 2 4
Leaving margin blank gives you proportions of the whole table
prop.table(m, margin=NULL)
[,1] [,2]
[1,] 0.1 0.3
[2,] 0.2 0.4
Giving it 1 gives you row proportions
prop.table(m, 1)
[,1] [,2]
[1,] 0.2500000 0.7500000
[2,] 0.3333333 0.6666667
And 2 is column proportions
prop.table(m, 2)
[,1] [,2]
[1,] 0.3333333 0.4285714
[2,] 0.6666667 0.5714286
It is true that this calculation does not make sense in a strict mathematical perspective, however if we are checking financial data it is still a useful metric. The formula could be the following:
if(lastyear>0,(thisyear/lastyear-1),((thisyear+abs(lastyear)/abs(lastyear))
let's verify the formula empirically with simple numbers:
thisyear=50 lastyear=25 growth=100%
makes sense
thisyear=25 lastyear=50 growth=-50%
makes sense
thisyear=-25 lastyear=25 growth=-200%
makes sense
thisyear=50 lastyear=-25 growth=300%
makes sense
thisyear=-50 lastyear=-25 growth=-100%
makes sense
thisyear=-25 lastyear=-50 growth=50%
makes sense
again, it might not be mathematically correct, but if you need meaningful numbers (maybe to plug them in graphs or other formulas) it's a good alternative to N/A, especially when using N/A could screw all subsequent calculations.
For a loop where you want to convert an array
of strings
to an array
of bigIntegers
do this:
String[] unsorted = new String[n]; //array of Strings
BigInteger[] series = new BigInteger[n]; //array of BigIntegers
for(int i=0; i<n; i++){
series[i] = new BigInteger(unsorted[i]); //convert String to bigInteger
}
The most upvoted solution generally works but for Spring and/or Spring Boot, the values will not wire to parameters in controller methods annotated with @RequestParam
unless you specifically implemented getParameterValues()
. I combined the solution(s) here and from this blog:
import java.util.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
public class MutableHttpRequest extends HttpServletRequestWrapper {
private final Map<String, String[]> mutableParams = new HashMap<>();
public MutableHttpRequest(final HttpServletRequest request) {
super(request);
}
public MutableHttpRequest addParameter(String name, String value) {
if (value != null)
mutableParams.put(name, new String[] { value });
return this;
}
@Override
public String getParameter(final String name) {
String[] values = getParameterMap().get(name);
return Arrays.stream(values)
.findFirst()
.orElse(super.getParameter(name));
}
@Override
public Map<String, String[]> getParameterMap() {
Map<String, String[]> allParameters = new HashMap<>();
allParameters.putAll(super.getParameterMap());
allParameters.putAll(mutableParams);
return Collections.unmodifiableMap(allParameters);
}
@Override
public Enumeration<String> getParameterNames() {
return Collections.enumeration(getParameterMap().keySet());
}
@Override
public String[] getParameterValues(final String name) {
return getParameterMap().get(name);
}
}
note that this code is not super-optimized but it works.
I got this error writing a Jasmine unit test. I had the line:

This is by far the best post for exporting to excel from SQL:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=49926
To quote from user madhivanan
,
Apart from using DTS and Export wizard, we can also use this query to export data from SQL Server2000 to Excel
Create an Excel file named testing having the headers same as that of table columns and use these queries
1 Export data to existing EXCEL file from SQL Server table
insert into OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:\testing.xls;',
'SELECT * FROM [SheetName$]') select * from SQLServerTable
2 Export data from Excel to new SQL Server table
select *
into SQLServerTable FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:\testing.xls;HDR=YES',
'SELECT * FROM [Sheet1$]')
3 Export data from Excel to existing SQL Server table (edited)
Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:\testing.xls;HDR=YES',
'SELECT * FROM [SheetName$]')
4 If you dont want to create an EXCEL file in advance and want to export data to it, use
EXEC sp_makewebtask
@outputfile = 'd:\testing.xls',
@query = 'Select * from Database_name..SQLServerTable',
@colheaders =1,
@FixedFont=0,@lastupdated=0,@resultstitle='Testing details'
(Now you can find the file with data in tabular format)
5 To export data to new EXCEL file with heading(column names), create the following procedure
create procedure proc_generate_excel_with_columns
(
@db_name varchar(100),
@table_name varchar(100),
@file_name varchar(100)
)
as
--Generate column names as a recordset
declare @columns varchar(8000), @sql varchar(8000), @data_file varchar(100)
select
@columns=coalesce(@columns+',','')+column_name+' as '+column_name
from
information_schema.columns
where
table_name=@table_name
select @columns=''''''+replace(replace(@columns,' as ',''''' as '),',',',''''')
--Create a dummy file to have actual data
select @data_file=substring(@file_name,1,len(@file_name)-charindex('\',reverse(@file_name)))+'\data_file.xls'
--Generate column names in the passed EXCEL file
set @sql='exec master..xp_cmdshell ''bcp " select * from (select '+@columns+') as t" queryout "'+@file_name+'" -c'''
exec(@sql)
--Generate data in the dummy file
set @sql='exec master..xp_cmdshell ''bcp "select * from '+@db_name+'..'+@table_name+'" queryout "'+@data_file+'" -c'''
exec(@sql)
--Copy dummy file to passed EXCEL file
set @sql= 'exec master..xp_cmdshell ''type '+@data_file+' >> "'+@file_name+'"'''
exec(@sql)
--Delete dummy file
set @sql= 'exec master..xp_cmdshell ''del '+@data_file+''''
exec(@sql)
After creating the procedure, execute it by supplying database name, table name and file path:
EXEC proc_generate_excel_with_columns 'your dbname', 'your table name','your file path'
Its a whomping 29 pages but that is because others show various other ways as well as people asking questions just like this one on how to do it.
Follow that thread entirely and look at the various questions people have asked and how they are solved. I picked up quite a bit of knowledge just skimming it and have used portions of it to get expected results.
To update single cells
A member also there Peter Larson posts the following: I think one thing is missing here. It is great to be able to Export and Import to Excel files, but how about updating single cells? Or a range of cells?
This is the principle of how you do manage that
update OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=c:\test.xls;hdr=no',
'SELECT * FROM [Sheet1$b7:b7]') set f1 = -99
You can also add formulas to Excel using this:
update OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=c:\test.xls;hdr=no',
'SELECT * FROM [Sheet1$b7:b7]') set f1 = '=a7+c7'
Exporting with column names using T-SQL
Member Mladen Prajdic also has a blog entry on how to do this here
References: www.sqlteam.com (btw this is an excellent blog / forum for anyone looking to get more out of SQL Server). For error referencing I used this
If you get the following error:
OLE DB provider 'Microsoft.Jet.OLEDB.4.0' cannot be used for distributed queries
Then run this:
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;
GO
Because gpcola's answer didn't work for me, I edited a bit so its works now. I used "margin-top" instead of transform. Also, i use the "show" instead of "shown" event because after it gave me a very bad jump of positioning (visible when you have bootstrap animations on). Be sure to set the display to "block" before positioning, otherwise $dialog.height() will be 0 and the modal will not be centered completely.
(function ($) {
"use strict";
function centerModal() {
$(this).css('display', 'block');
var $dialog = $(this).find(".modal-dialog"),
offset = ($(window).height() - $dialog.height()) / 2,
bottomMargin = parseInt($dialog.css('marginBottom'), 10);
// Make sure you don't hide the top part of the modal w/ a negative margin if it's longer than the screen height, and keep the margin equal to the bottom margin of the modal
if(offset < bottomMargin) offset = bottomMargin;
$dialog.css("margin-top", offset);
}
$(document).on('show.bs.modal', '.modal', centerModal);
$(window).on("resize", function () {
$('.modal:visible').each(centerModal);
});
}(jQuery));
Just to add to the existing great answers here - building on the code in the accepted one, which uses a delegate void MyEventHandler(string foo)
...
Because the compiler knows the delegate type of the SomethingHappened event, this:
myObj.SomethingHappened += HandleSomethingHappened;
Is totally equivalent to:
myObj.SomethingHappened += new MyEventHandler(HandleSomethingHappened);
And handlers can also be unregistered with -=
like this:
// -= removes the handler from the event's list of "listeners":
myObj.SomethingHappened -= HandleSomethingHappened;
For completeness' sake, raising the event can be done like this, only in the class that owns the event:
//Firing the event is done by simply providing the arguments to the event:
var handler = SomethingHappened; // thread-local copy of the event
if (handler != null) // the event is null if there are no listeners!
{
handler("Hi there!");
}
The thread-local copy of the handler is needed to make sure the invocation is thread-safe - otherwise a thread could go and unregister the last handler for the event immediately after we checked if it was null
, and we would have a "fun" NullReferenceException
there.
C# 6 introduced a nice short hand for this pattern. It uses the null propagation operator.
SomethingHappened?.Invoke("Hi there!");
For the vast majority[1] of visitors here, the correct and simplest answer to the question "How do I list all remote branches in Git 1.7+?" is:
git branch -r
For a small minority[1] git branch -r
does not work. If git branch -r
does not work try:
git ls-remote --heads <remote-name>
If git branch -r
does not work, then maybe as Cascabel says "you've modified the default refspec, so that git fetch
and git remote update
don't fetch all the remote
's branches".
[1] As of the writing of this footnote 2018-Feb, I looked at the comments and see that the git branch -r
works for the vast majority (about 90% or 125 out of 140).
If git branch -r
does not work, check git config --get remote.origin.fetch
contains a wildcard (*
) as per this answer
You have two options to abruptly exit out of ForEach-Object
pipeline in PowerShell:
Where-Object
first, then pass objects to Foreach-Object
, orForeach-Object
into a standard Foreach
looping construct.Let's see examples: Following scripts exit out of Foreach-Object loop after 2nd iteration (i.e. pipeline iterates only 2 times)":
Solution-1: use Where-Object
filter BEFORE Foreach-Object
:
[boolean]$exit = $false;
1..10 | Where-Object {$exit -eq $false} | Foreach-Object {
if($_ -eq 2) {$exit = $true} #OR $exit = ($_ -eq 2);
$_;
}
OR
1..10 | Where-Object {$_ -le 2} | Foreach-Object {
$_;
}
Solution-2: Converted Foreach-Object
into standard Foreach
looping construct:
Foreach ($i in 1..10) {
if ($i -eq 3) {break;}
$i;
}
PowerShell should really provide a bit more straightforward way to exit or break out from within the body of a Foreach-Object
pipeline. Note: return
doesn't exit, it only skips specific iteration (similar to continue
in most programming languages), here is an example of return
:
Write-Host "Following will only skip one iteration (actually iterates all 10 times)";
1..10 | Foreach-Object {
if ($_ -eq 3) {return;} #skips only 3rd iteration.
$_;
}

In fact, it is very easy.
composer update
will do all this for you, but it will also update the other packages.
To remove a package without updating the others, specifiy that package in the command, for instance:
composer update monolog/monolog
will remove the monolog/monolog
package.
Nevertheless, there may remain some empty folders or files that cannot be removed automatically, and that have to be removed manually.
David Crawshaw project(sqlitejdbc-v056.jar) seems out of date and last update was Jun 20, 2009, source here
I would recomend Xerials fork of Crawshaw sqlite wrapper. I replaced sqlitejdbc-v056.jar with Xerials sqlite-jdbc-3.7.2.jar file without any problem.
Uses same syntax as in Bernie's answer and is much faster and with latest sqlite library.
What is different from Zentus's SQLite JDBC?
The original Zentus's SQLite JDBC driver http://www.zentus.com/sqlitejdbc/ itself is an excellent utility for using SQLite databases from Java language, and our SQLiteJDBC library also relies on its implementation. However, its pure-java version, which totally translates c/c++ codes of SQLite into Java, is significantly slower compared to its native version, which uses SQLite binaries compiled for each OS (win, mac, linux).
To use the native version of sqlite-jdbc, user had to set a path to the native codes (dll, jnilib, so files, which are JNDI C programs) by using command-line arguments, e.g., -Djava.library.path=(path to the dll, jnilib, etc.), or -Dorg.sqlite.lib.path, etc. This process was error-prone and bothersome to tell every user to set these variables. Our SQLiteJDBC library completely does away these inconveniences.
Another difference is that we are keeping this SQLiteJDBC libray up-to-date to the newest version of SQLite engine, because we are one of the hottest users of this library. For example, SQLite JDBC is a core component of UTGB (University of Tokyo Genome Browser) Toolkit, which is our utility to create personalized genome browsers.
EDIT : As usual when you update something, there will be problems in some obscure place in your code(happened to me). Test test test =)
If you want to feel especially sly, you can write it as this:
(firstWord, rest) = yourLine.split(maxsplit=1)
This is supposed to bring the best from both worlds:
maxsplit
while splitting with any whitespaceI kind of fell in love with this solution and it's general unpacking capability, so I had to share it.
This problem has hounded me for some days now, so on finding the answer that affirmatively works with tvanfosson's answer above, I thought it would be worthwhile to emphasize the core part of the answer, and address some related catch ya's.
The core answer is this, sweet and simple:
filterContext.Result = new HttpUnauthorizedResult();
In my case I inherit from a base controller, so in each controller that inherits from it I override OnAuthorize:
protected override void OnAuthorization(AuthorizationContext filterContext)
{
base.OnAuthorization(filterContext);
YourAuth(filterContext); // do your own authorization logic here
}
The problem was that in 'YourAuth', I tried two things that I thought would not only work, but would also immediately terminate the request. Well, that is not how it works. So first, the two things that DO NOT work, unexpectedly:
filterContext.RequestContext.HttpContext.Response.Redirect("/Login"); // doesn't work!
FormsAuthentication.RedirectToLoginPage(); // doesn't work!
Not only do those not work, they don't end the request either. Which means the following:
if (!success) {
filterContext.Result = new HttpUnauthorizedResult();
}
DoMoreStuffNowThatYouThinkYourAuthorized();
Well, even with the correct answer above, the flow of logic still continues! You will still hit DoMoreStuff... within OnAuthorize. So keep that in mind (DoMore... should be in an else therefore).
But with the correct answer, while OnAuthorize flow of logic continues till the end still, after that you really do get what you expect: a redirect to your login page (if you have one set in Forms auth in your webconfig).
But unexpectedly, 1) Response.Redirect("/Login") does not work: the Action method still gets called, and 2) FormsAuthentication.RedirectToLoginPage(); does the same thing: the Action method still gets called!
Which seems totally wrong to me, particularly with the latter: who would have thought that FormsAuthentication.RedirectToLoginPage does not end the request, or do the equivalant above of what filterContext.Result = new HttpUnauthorizedResult() does?
If your server certificated file is not trusted, (for example, you may generate the keystore by yourself with keytool command in java), you should add the extra option rejectUnauthorized
var socket = io.connect('https://localhost', {rejectUnauthorized: false});
The RegExp constructor creates a regular expression object for matching text with a pattern.
var pattern1 = ':\\(|:=\\(|:-\\(';
var pattern2 = ':\\(|:=\\(|:-\\(|:\\(|:=\\(|:-\\(';
var regex = new RegExp(pattern1 + '|' + pattern2, 'gi');
str.match(regex);
Above code works perfectly for me...
You inherit class attributes, not class constructors .This is how it goes :
If no constructor is added in the super class, if no then the compiler adds a no argument contructor. This default constructor is invoked implicitly whenever a new instance of the sub class is created . Here the sub class may or may not have constructor, all is ok .
if a constructor is provided in the super class, the compiler will see if it is a no arg constructor or a constructor with parameters.
if no args, then the compiler will invoke it for any sub class instanciation . Here also the sub class may or may not have constructor, all is ok .
if 1 or more contructors in the parent class have parameters and no args constructor is absent, then the subclass has to have at least 1 constructor where an implicit call for the parent class construct is made via super (parent_contractor params) .
this way you are sure that the inherited class attributes are always instanciated .
They are names for the same standard from two different industries with different naming methods, the guys who make & sell movies and the guys who transfer the movies over the internet. Since 2003: "MPEG 4 Part 10" = "H.264" = "AVC". Before that the relationship was a little looser in that they are not equal but an "MPEG 4 Part 2" decoder can render a stream that's "H.263". The Next standard is "MPEG H Part 2" = "H.265" = "HEVC"
Some information is stored in the cookie which is related to previous versions of laravel in development. So it's conflicting with csrf generated tokens which are generated by another's versions. Just Clear the cookie and give a try.
I had the experienced the same issue in different context of my project and there are different scenarios like
- object is accessed from various source like (server side and client)
- without any interval accessing the same object from a different place
In the first case
When I issue a server cal, before save the that object their one call from js and trying to save and another place, I got like, js call is going two, three times(I thing that call binding thing cause the issue)
I solved by
e.preventDefault()
The second case,
object.lock()
The problem is that the root's (the main layout you store the other elements) gravity is not set. If you change it to center the other elements' gravity must work just fine.
Here's a demonstration page that uses slowAES.
slowAES was easy to use. Logically designed. Reasonable OO packaging. Supports knobs and levers like IV and Encryption mode. Good compatibility with .NET/C#. The name is tongue-in-cheek; it's called "slow AES" because it's not implemented in C++. But in my tests it was not impractically slow.
It lacks an ECB mode. Also lacks a CTR mode, although you could build one pretty easily given an ECB mode, I guess.
It is solely focused on encryption. A nice complementary class that does RFC2898-compliant password-based key derivation, in Javascript, is available from Anandam. This pair of libraries works well with the analogous .NET classes. Good interop. Though, in contrast to SlowAES, the Javascript PBKDF2 is noticeably slower than the Rfc2898DeriveBytes class when generating keys.
It's not surprising that technically there is good interop, but the key point for me was the model adopted by SlowAES is familiar and easy to use. I found some of the other Javascript libraries for AES to be hard to understand and use. For example, in some of them I couldn't find the place to set the IV, or the mode (CBC, ECB, etc). Things were not where I expected them to be. SlowAES was not like that. The properties were right where I expected them to be. It was easy for me to pick up, having been familiar with the Java and .NET crypto programming models.
Anandam's PBKDF2 was not quite on that level. It supported only a single call to DeriveBytes function, so if you need to derive both a key and an IV from a password, this library won't work, unchanged. Some slight modification, and it is working just fine for that purpose.
EDIT: I put together an example of packaging SlowAES and a modified version of Anandam's PBKDF2 into Windows Script Components. Using this AES with a password-derived key shows good interop with the .NET RijndaelManaged class.
EDIT2: the demo page shows how to use this AES encryption from a web page. Using the same inputs (iv, key, mode, etc) supported in .NET gives you good interop with the .NET Rijndael class. You can do a "view source" to get the javascript for that page.
EDIT3
a late addition: Javascript Cryptography considered harmful. Worth the read.
If it's not a big/long array just mirror it:
for( int i = 0; i < arr.length/2; ++i )
{
temp = arr[i];
arr[i] = arr[arr.length - i - 1];
arr[arr.length - i - 1] = temp;
}
I'm late to the party here, but there's an awesome library I've been using which I haven't seen referenced in the other answers
https://github.com/brminnick/AsyncAwaitBestPractices
If you need to "Fire And Forget" you call the extension method on the task.
Passing the action onException to the call ensures that you get the best of both worlds - no need to await execution and slow your users down, whilst retaining the ability to handle the exception in a graceful manner.
In your example you would use it like this:
public string GetStringData()
{
MyAsyncMethod().SafeFireAndForget(onException: (exception) =>
{
//DO STUFF WITH THE EXCEPTION
});
return "hello world";
}
It also gives awaitable AsyncCommands implementing ICommand out the box which is great for my MVVM Xamarin solution
Array.filter is not implemented in many browsers,It is better to define this function if it does not exist.
The source code for Array.prototype is posted in MDN
if (!Array.prototype.filter)
{
Array.prototype.filter = function(fun /*, thisp */)
{
"use strict";
if (this == null)
throw new TypeError();
var t = Object(this);
var len = t.length >>> 0;
if (typeof fun != "function")
throw new TypeError();
var res = [];
var thisp = arguments[1];
for (var i = 0; i < len; i++)
{
if (i in t)
{
var val = t[i]; // in case fun mutates this
if (fun.call(thisp, val, i, t))
res.push(val);
}
}
return res;
};
}

As mentioned by other answers, as of now android studio does not provide this out of the box. However, there are ways to do this easily.
As mentioned by @Elad Lavi, you should consider cloud hosting of your source code. Checkout github, bitbucket, gitlab, etc. All these provide private repositories, some free, some not.
If all you want is to just zip the sources, you can achieve this using git's git archive
. Here are the steps:
git init # on the root of the project folder
git add . # note: android studio already created .gitignore
git commit -m 'ready to zip sources'
git archive HEAD --format=zip > /tmp/archive.zip
Note: If you intend to send this by email, you have to remove gradlew.bat from zip file.
Both these solutions are possible thanks to VCS like git.
radian can also be converted to degree by using numpy
print(np.rad2deg(1))
57.29577951308232
if needed to roundoff ( I did with 6 digits after decimal below), then
print(np.round(np.rad2deg(1), 6)
57.29578
As I understand, you want the average value for each id at each pass. The solution is
SELECT id, pass, avg(value) FROM data_r1
GROUP BY id, pass;
Convert.ToInt32(myobject);
This will handle the case where myobject is null and return 0, instead of throwing an exception.
I would make a new image of the dog's silhouette (black) and the rest the same as the original image. In the html, add a wrapper div with this silhouette as as background. Now, make the original image semi-transparent. The dog will become darker and the background of the dog will stay the same. You can do :hover tricks by setting the opacity of the original image to 100% on hover. Then the dog pops out when you mouse over him!
style
.wrapper{background-image:url(silhouette.png);}
.original{opacity:0.7:}
.original:hover{opacity:1}
<div class="wrapper">
<div class="img">
<img src="original.png">
</div>
</div>
These two commands should do it:

For bonus points put them in a file named .vimrc located in your home directory on linux
You can inspect elements of a website in your Android device using Chrome browser.
Open your Chrome browser and go to the website you want to inspect.
Go to the address bar and type "view-source:" before the "HTTP" and reload the page.
The whole elements of the page will be shown.
Set the form's .TopMost
property to true.
You probably don't want to leave it this way all the time: set it when your external process starts and put it back when it finishes.
If you go to C:\Windows\system32\Windowspowershell\v1.0
(and C:\Windows\syswow64\Windowspowershell\v1.0
on x64 machines) in Windows Explorer and double-click powershell.exe
you will see that it opens PowerShell with a black background. The PowerShell console shows up as blue when opened from the start menu because the console properties for shortcuts to powershell.exe
can be set independently from the default properties.
To set the default options, font, colors and layout, open a PowerShell console, type Alt-Space, and select the Defaults menu option.
Running start powershell
from cmd.exe should start a new console with your default settings.
Kotlin:
You can also use CountDownTimer:
class Timer {
companion object {
@JvmStatic
fun call(ms: Long, f: () -> Unit) {
object : CountDownTimer(ms,ms){
override fun onFinish() { f() }
override fun onTick(millisUntilFinished: Long) {}
}.start()
}
}
}
And in your code:
Timer.call(5000) { /*Whatever you want to execute after 5000 ms*/ }
Here is an extension/edit of VonCs solution just in case someone doesn´t want to go through the hassle of implementing their own filter to do this. It also shows how to output a JAXB element without the namespace present. This is all accomplished using a SAX Filter.
Filter implementation:
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.XMLFilterImpl;
public class NamespaceFilter extends XMLFilterImpl {
private String usedNamespaceUri;
private boolean addNamespace;
//State variable
private boolean addedNamespace = false;
public NamespaceFilter(String namespaceUri,
boolean addNamespace) {
super();
if (addNamespace)
this.usedNamespaceUri = namespaceUri;
else
this.usedNamespaceUri = "";
this.addNamespace = addNamespace;
}
@Override
public void startDocument() throws SAXException {
super.startDocument();
if (addNamespace) {
startControlledPrefixMapping();
}
}
@Override
public void startElement(String arg0, String arg1, String arg2,
Attributes arg3) throws SAXException {
super.startElement(this.usedNamespaceUri, arg1, arg2, arg3);
}
@Override
public void endElement(String arg0, String arg1, String arg2)
throws SAXException {
super.endElement(this.usedNamespaceUri, arg1, arg2);
}
@Override
public void startPrefixMapping(String prefix, String url)
throws SAXException {
if (addNamespace) {
this.startControlledPrefixMapping();
} else {
//Remove the namespace, i.e. don´t call startPrefixMapping for parent!
}
}
private void startControlledPrefixMapping() throws SAXException {
if (this.addNamespace && !this.addedNamespace) {
//We should add namespace since it is set and has not yet been done.
super.startPrefixMapping("", this.usedNamespaceUri);
//Make sure we dont do it twice
this.addedNamespace = true;
}
}
}
This filter is designed to both be able to add the namespace if it is not present:
new NamespaceFilter("http://www.example.com/namespaceurl", true);
and to remove any present namespace:
new NamespaceFilter(null, false);
The filter can be used during parsing as follows:
//Prepare JAXB objects
JAXBContext jc = JAXBContext.newInstance("jaxb.package");
Unmarshaller u = jc.createUnmarshaller();
//Create an XMLReader to use with our filter
XMLReader reader = XMLReaderFactory.createXMLReader();
//Create the filter (to add namespace) and set the xmlReader as its parent.
NamespaceFilter inFilter = new NamespaceFilter("http://www.example.com/namespaceurl", true);
inFilter.setParent(reader);
//Prepare the input, in this case a java.io.File (output)
InputSource is = new InputSource(new FileInputStream(output));
//Create a SAXSource specifying the filter
SAXSource source = new SAXSource(inFilter, is);
//Do unmarshalling
Object myJaxbObject = u.unmarshal(source);
To use this filter to output XML from a JAXB object, have a look at the code below.
//Prepare JAXB objects
JAXBContext jc = JAXBContext.newInstance("jaxb.package");
Marshaller m = jc.createMarshaller();
//Define an output file
File output = new File("test.xml");
//Create a filter that will remove the xmlns attribute
NamespaceFilter outFilter = new NamespaceFilter(null, false);
//Do some formatting, this is obviously optional and may effect performance
OutputFormat format = new OutputFormat();
format.setIndent(true);
format.setNewlines(true);
//Create a new org.dom4j.io.XMLWriter that will serve as the
//ContentHandler for our filter.
XMLWriter writer = new XMLWriter(new FileOutputStream(output), format);
//Attach the writer to the filter
outFilter.setContentHandler(writer);
//Tell JAXB to marshall to the filter which in turn will call the writer
m.marshal(myJaxbObject, outFilter);
This will hopefully help someone since I spent a day doing this and almost gave up twice ;)

Using final in a method parameter has nothing to do with what happens to the argument on the caller side. It is only meant to mark it as not changing inside that method. As I try to adopt a more functional programming style, I kind of see the value in that.
If you look at the standard libraries the pattern generally is my_function, but every person does seem to have their own way :-/
I had the same problem with mediawiki, this was because the server denied embedding the page into an iframe for security reasons.

Usually the desire is to match the menu width to the width of the dropdown parent. This can be achieved easily like so:

One of my SQL jobs had the same issue. It involved uploadaing data from one server to another. The error occurred because I was using sql Server Agent Service Account. I created a Credential using a UserId (that uses Window authentication) common to all servers. Then created a Proxy using this credential. Used the proxy in sql server job and it is running fine.
overrides:
- files: *-tests.js
rules:
no-param-reassign: 0
You can also set a specific env for a folder, like this :
overrides:
- files: test/*-tests.js
env:
mocha: true
This configuration will fix error message about describe
and it
not defined, only for your test folder:
/myproject/test/init-tests.js
6:1 error 'describe' is not defined no-undef
9:3 error 'it' is not defined no-undef
Windows dll error 126 can have many root causes. The most useful methods I have found to debug this are:
create view sampleView as
select field1, field2, ...
from dbo.MyTableValueFunction
Note that even if your MyTableValueFunction doesn't accept any parameters, you still need to include parentheses after it, i.e.:
... from dbo.MyTableValueFunction()
Without the parentheses, you'll get an "Invalid object name" error.
.outerdiv {
margin-left: auto;
margin-right: auto;
display: table;
}
Doesn't work in internet explorer 7... but who cares ?
You can check the availability of the view in various ways

SELECT 1
FROM sys.objects
WHERE OBJECT_ID = OBJECT_ID('[schemaName].[ViewName]')
AND Type_Desc = 'VIEW'
)

END
use sysobjects
IF NOT EXISTS (
SELECT 1
FROM sysobjects
WHERE NAME = '[schemaName].[ViewName]'
AND xtype = 'V'
)

END
use sys.views
IF EXISTS (
SELECT 1

PRINT 'View Exists'
END
use INFORMATION_SCHEMA.VIEWS
IF EXISTS (
SELECT 1

AND table_schema = 'schemaName'
)
BEGIN
PRINT 'View Exists'
END
use OBJECT_ID
IF EXISTS(
SELECT OBJECT_ID('ViewName', 'V')
)
BEGIN
PRINT 'View Exists'
END
use sys.sql_modules
IF EXISTS (
SELECT 1
FROM sys.sql_modules
WHERE OBJECT_ID = OBJECT_ID('[schemaName].[ViewName]')
)
BEGIN
PRINT 'View Exists'
END
If you don't like libraries, how about this?
Note that you should not use this function on the whole URL, instead you should use this on the components...e.g. just the "a b" component, as you build up the URL - otherwise the computer won't know what characters are supposed to have a special meaning and which ones are supposed to have a literal meaning.
/** Converts a string into something you can safely insert into a URL. */
public static String encodeURIcomponent(String s)
{

for (char ch : s.toCharArray()) {
if (isUnsafe(ch)) {
o.append('%');
o.append(toHex(ch / 16));
o.append(toHex(ch % 16));
}
else o.append(ch);
}
return o.toString();

As explained in Python's super() considered super, one way is to have class eat the arguments it requires, and pass the rest on. Thus, when the call-chain reaches object
, all arguments have been eaten, and object.__init__
will be called without arguments (as it expects). So your code should look like this:
class A(object):
def __init__(self, *args, **kwargs):
print "A"
super(A, self).__init__(*args, **kwargs)
class B(object):
def __init__(self, *args, **kwargs):
print "B"
super(B, self).__init__(*args, **kwargs)
class C(A):
def __init__(self, arg, *args, **kwargs):
print "C","arg=",arg
super(C, self).__init__(*args, **kwargs)
class D(B):
def __init__(self, arg, *args, **kwargs):
print "D", "arg=",arg
super(D, self).__init__(*args, **kwargs)
class E(C,D):
def __init__(self, arg, *args, **kwargs):
print "E", "arg=",arg
super(E, self).__init__(*args, **kwargs)
print "MRO:", [x.__name__ for x in E.__mro__]
E(10, 20, 30)
If you already have a rails project, change the adapter in the config/database.yml
file to mysql
and make sure you specify a valid username and password, and optionally, a socket:
development:
adapter: mysql2
database: db_name_dev
username: koploper
password:
host: localhost
socket: /tmp/mysql.sock
Next, make sure you edit your Gemfile to include the mysql2 or activerecord-jdbcmysql-adapter (if using jruby).
OMG Ponies's answer works perfectly, but just in case you need something more complex, here is an example of a slightly more advanced update query:
UPDATE table1
SET col1 = subquery.col2,
col2 = subquery.col3
FROM (
SELECT t2.foo as col1, t3.bar as col2, t3.foobar as col3
FROM table2 t2 INNER JOIN table3 t3 ON t2.id = t3.t2_id
WHERE t2.created_at > '2016-01-01'
) AS subquery
WHERE table1.id = subquery.col1;
In Ubuntu, from MySQL monitor, you have already used this syntax:
mysql> use <dbname>
-> The USE statement tells MySQL to use dbname
as the default database for subsequent statements
mysql> source <file-path>
for example:
mysql> use phonebook;
mysql> source /tmp/phonebook.sql;
Important: make sure the sql file is in a directory that mysql can access to like /tmp
I faced a similar issue. I was copying the velocity engine mail templates in wrong folder. Since JavaMailSender and VelocityEngine are declared as resources under MailService, its required to add the templates under resource folder declared for the project.
I made the changes and it worked. Put the templates as

You can use 'this' in event handler:
document.getElementById("preview").onmouseover = function() {
alert(this.id);
}
Or pass event object to handler as follows:
document.getElementById("preview").onmouseover = function(evt) {
alert(evt.target.id);
}
It's recommended to use attachEvent(for IE < 9)/addEventListener(IE9 and other browsers) to attach events. Example above is for brevity.
function myHandler(evt) {
alert(evt.target.id);
}
var el = document.getElementById("preview");
if (el.addEventListener){
el.addEventListener('click', myHandler, false);
} else if (el.attachEvent){
el.attachEvent('onclick', myHandler);
}
That is a Python bug between "*" and special characters.

public ICommand ClickCommand
{

{
return _clickCommand ?? (_clickCommand = new CommandHandler(() => MyAction(), ()=> CanExecute));
}
}
public bool CanExecute
{
get
{
// check if executing is allowed, i.e., validate, check if a process is running, etc.
return true/false;
}
}
public void MyAction()
{
}
}
Command Handler:
public class CommandHandler : ICommand
{
private Action _action;
private Func<bool> _canExecute;
/// <summary>
/// Creates instance of the command handler
/// </summary>
/// <param name="action">Action to be executed by the command</param>
/// <param name="canExecute">A bolean property to containing current permissions to execute the command</param>
public CommandHandler(Action action, Func<bool> canExecute)
{
_action = action;
_canExecute = canExecute;
}
/// <summary>
/// Wires CanExecuteChanged event
/// </summary>
public event EventHandler CanExecuteChanged
{
add { CommandManager.RequerySuggested += value; }
remove { CommandManager.RequerySuggested -= value; }
}
/// <summary>
/// Forcess checking if execute is allowed
/// </summary>
/// <param name="parameter"></param>
/// <returns></returns>
public bool CanExecute(object parameter)
{
return _canExecute.Invoke();
}
public void Execute(object parameter)
{
_action();
}
}
I hope this will give you the idea.
That is not possible. A function that has a non-void return type (even if it's Void
) has to return a value. However you could add static methods to Action
that allows you to "create" a Action
:
interface Action<T, U> {
U execute(T t);
public static Action<Void, Void> create(Runnable r) {
return (t) -> {r.run(); return null;};
}
public static <T, U> Action<T, U> create(Action<T, U> action) {
return action;
}
}
That would allow you to write the following:
// create action from Runnable
Action.create(()-> System.out.println("Hello World")).execute(null);
// create normal action
System.out.println(Action.create((Integer i) -> "number: " + i).execute(100));
There is one more solution to achieve this. It was described here. The idea is subclassing UILabel
and overriding action(for:forKey:)
function in the following way:
class LabelWithAnimatedText: UILabel {
override var text: String? {
didSet {
self.layer.setValue(self.text, forKey: "text")
}
}
override func action(for layer: CALayer, forKey event: String) -> CAAction? {
if event == "text" {
if let action = self.action(for: layer, forKey: "backgroundColor") as? CAAnimation {
let transition = CATransition()
transition.type = kCATransitionFade
//CAMediatiming attributes
transition.beginTime = action.beginTime
transition.duration = action.duration
transition.speed = action.speed
transition.timeOffset = action.timeOffset
transition.repeatCount = action.repeatCount
transition.repeatDuration = action.repeatDuration
transition.autoreverses = action.autoreverses
transition.fillMode = action.fillMode
//CAAnimation attributes
transition.timingFunction = action.timingFunction
transition.delegate = action.delegate
return transition
}
}
return super.action(for: layer, forKey: event)
}
}
Usage examples:
// do not forget to set the "Custom Class" IB-property to "LabelWithAnimatedText"
// @IBOutlet weak var myLabel: LabelWithAnimatedText!
// ...
UIView.animate(withDuration: 0.5) {
myLabel.text = "I am animated!"
}
myLabel.text = "I am not animated!"
I know this is an old question, but since php7.0 you can use the null coalescing operator (another resource).
It similar to the ternary operator, but will behave like isset on the lefthand operand instead of just using its boolean value.
$slide = $_GET["id"] ?? 'fallback';
So if $_GET["id"]
is set, it returns the value. If not, it returns the fallback. I found this very helpful for $_POST, $_GET, or any passed parameters, etc
$slide = $_GET["id"] ?? '';
if (trim($slide) == 'link1') ...

to

Boostrap's class .col-xx-push-X
does nothing else but pushes a column to the right with left: XX%;
so all you have to do to push a column right is to add the number of pseudo columns going left.
In this case:
two columns (col-md-5
and col-md-3
) are going left, each with the value of the one that is going right;
one(col-md-4
) is going right by the sum of the first two going left (5+3=8);

In this case my target was to change the Button's text color (Button_C) when I change the color selection from my Preferences (color_prefs).

Your object can also implement the Parcelable interface. Then you can use the Bundle.putParcelable()
method and pass your object between activities within intent.
The Photostream application uses this approach and may be used as a reference.
Matplot colors your plot with different colors , but incase you wanna put specific colors
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(10)
plt.plot(x, x)
plt.plot(x, 2 * x,color='blue')
plt.plot(x, 3 * x,color='red')
plt.plot(x, 4 * x,color='green')
plt.show()
The reason I used a +
instead of a '*' is because a plus is defined as one or more of the preceding element, where an asterisk is zero or more. In this case we want a delimiter that's a little more concrete, so "one or more" spaces.
word[Aa]\s+word[Bb]\s+word[Cc]
will match:
wordA wordB wordC
worda wordb wordc
wordA wordb wordC
The words, in this expression, will have to be specific, and also in order (a, b, then c)

The simplest (not the best or ideal) solution I found was to use react-native-dotenv. You simply add the "react-native-dotenv" preset to your .babelrc
file at the project root like so:
{
"presets": ["react-native", "react-native-dotenv"]
}
Create a .env
file and add properties:
echo "SOMETHING=anything" > .env
Then in your project (JS):
import { SOMETHING } from 'react-native-dotenv'
console.log(SOMETHING) // "anything"
Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin
not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors
at your server side.
You can fetch request using mode: 'cors'
. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.
So in both condition you need to configure cors
in your server or you need to use custom proxy server.

Be aware that there is no single, standard way in which browsers/email clients handle mailto links (e.g. subject and body fields may be discarded without a warning). Also there is a risk that popup and ad blockers, anti-virus software etc. may silently block forced opening of mailto links.
Polymorphism means more than one form, same object performing different operations according to the requirement.
Polymorphism can be achieved by using two ways, those are
Method overloading means writing two or more methods in the same class by using same method name, but the passing parameters is different.
Method overriding means we use the method names in the different classes,that means parent class method is used in the child class.
In Java to achieve polymorphism a super class reference variable can hold the sub class object.
To achieve the polymorphism every developer must use the same method names in the project.
Ok, you've declared junit
dependency for test
classes only (those that are in src/test/java
but you're trying to use it in main
classes (those that are in src/main/java
).
Either do not use it in main classes, or remove <scope>test</scope>
.
In Bash and zsh you can do this with Brace Expansion. This simply expands a list of items in braces. For example:
# echo {vanilla,chocolate,strawberry}-ice-cream
vanilla-ice-cream chocolate-ice-cream strawberry-ice-cream
So you can do your rename as follows:
mv {,new.}original.filename
as this expands to:
mv original.filename new.original.filename
You can clear the input field by using $('#shares').val('');
If you just want to get the path to a certain action, use UrlHelper
:
UrlHelper u = new UrlHelper(this.ControllerContext.RequestContext);
string url = u.Action("About", "Home", null);
if you want to create a hyperlink:
string link = HtmlHelper.GenerateLink(this.ControllerContext.RequestContext, System.Web.Routing.RouteTable.Routes, "My link", "Root", "About", "Home", null, null);
Intellisense will give you the meaning of each of the parameters.
Update from comments: controller already has a UrlHelper
:
string url = this.Url.Action("About", "Home", null);
$client = new \GuzzleHttp\Client();
$request = $client->post('http://demo.website.com/api', [
'body' => json_encode($dataArray)
]);
$response = $request->getBody();
Add
openssl.cafile
in php.ini
file
In your invoke web request just use the parameter -UseBasicParsing
e.g. in your script (line 2) you should use:
$rss = Invoke-WebRequest -UseBasicParsing
According to the documentation, this parameter is necessary on systems where IE isn't installed or configured.
Uses the response object for HTML content without Document Object Model (DOM) parsing. This parameter is required when Internet Explorer is not installed on the computers, such as on a Server Core installation of a Windows Server operating system.
One simple solution if only one button needs to be centered is something like:
<input type='submit' style='display:flex; justify-content:center;' value='Submit'>
You can use a similar style to handle several buttons.
You might need to grep Foobar directory like:
find . -name "file.ext"| grep "FooBar" | xargs -i cp -p "{}" .
You need a regular expression like "\\s+"
, which means: split whenever at least one whitespace is encountered. The full Java code is:
try {
String[] splitArray = input.split("\\s+");
} catch (PatternSyntaxException ex) {
//
}
I solved it by using the developer tools for IE7 (its a toolbar) and adding a negative z-index to the container of the div that will be below that the other div.
this could be a possible code solution:
from skimage import io
import numpy as np
data=np.random.randn(5,2)
io.imshow(data)
Note that adjusting the width of a column in the thead will affect the whole table
<table>
<thead>
<tr width="25">
<th>Name</th>
<th>Email</th>
</tr>
</thead>
<tr>
<td>Joe</td>
<td>[email protected]</td>
</tr>
</table>
In my case, the width on the thead > tr was overriding the width on table > tr > td directly.
char firstLetter = someString.charAt(0);
String oneLetter = String.valueOf(someChar);
You find the documentation by identifying the classes likely to be involved. Here, candidates are java.lang.String
and java.lang.Character
.
You should start by familiarizing yourself with:
java.lang
java.util
It also helps to get introduced to the API more slowly through tutorials.
I am even later to this party, but after spending about 2 hours trying everything imaginable and not having any luck, I finally realized it will work if I upload the pics to GOOGLE PHOTOS instead of GOOGLE DRIVE. Then I can right-click on the pic, copy the address, paste it in, and it works beautifully.

I've tried so many solutions, some of them works on Windows XP and all of them did NOT work on Windows 7. After all I write a simple method to do so.
private void GoFullscreen(bool fullscreen)
{
if (fullscreen)
{
this.WindowState = FormWindowState.Normal;
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.Bounds = Screen.PrimaryScreen.Bounds;
}
else
{
this.WindowState = FormWindowState.Maximized;
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.Sizable;
}
}
the order of code is important and will not work if you change the place of WindwosState and FormBorderStyle.
One of the advantages of this method is leaving the TOPMOST on false that allow other forms to come over the main form.
It absolutely solved my problem.
@EH_warch You need to use the Complete callback to generate your base64:
onAnimationComplete: function(){
console.log(this.toBase64Image())
}
If you see a white image, it means you called the toBase64Image before it finished rendering.
The Android Studio website has recently (I think) provided some advice what kind of messages to expect from different log levels that may be useful along with Kurtis' answer:
I know the question is about setting a input but just in case if you want to set a combobox then (I search net for it and didn't find anything and this place seems a right place to guide others)
If you had a form with ID attribute set (e.g. frm1) and you wanted to set a specific specific combobox, with no ID set but name attribute set (e.g. district); then use
$("#frm1 select[name='district'] option[value='NWFP']").attr('selected', true);
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>_x000D_
<form id="frm1">_x000D_
<select name="district">_x000D_
<option value="" disabled="" selected="" hidden="">Area ...</option>_x000D_
<option value="NWFP">NWFP</option>_x000D_
<option value="FATA">FATA</option>_x000D_
</select>_x000D_
</form>
_x000D_
Change visible="false"
to style="visibility:hidden"
on your tags..
or better use a class to show/hide the labels..
.hidden{
visibility:hidden;
}
then on your labels add class="hidden"
and with your script remove the class
document.getElementById("endTimeLabel").className = 'hidden'; // to hide
and
document.getElementById("endTimeLabel").className = ''; // to show
Call dialog.setCancelable(false);
from your activity/fragment.
I found a work around but with this I'll need to annotate each date's setter throughout the project. Is there a way in which I can specify the format while creating the ObjectMapper?
Here's what I did:
public class CustomJsonDateDeserializer extends JsonDeserializer<Date>
{
@Override
public Date deserialize(JsonParser jsonParser,
DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
String date = jsonParser.getText();
try {
return format.parse(date);
} catch (ParseException e) {
throw new RuntimeException(e);
}
}
}
And annotated each Date field's setter method with this:
@JsonDeserialize(using = CustomJsonDateDeserializer.class)
import sys
sys.argv[1:]
will give you a list of arguments (not including the name of the python file)
If you have problems with numbers (say 1, 2, 10, 12 which will be sorted 1, 10, 12, 2) you can use LINQ:
var arr = arr.OrderBy(x=>x).ToArray();
You can also use a combination of cat
and paste0
cat(paste0("File not supplied.\n", "Usage: ./program F=filename"))
I find this to be more useful when incorporating variables into the printout. For example:
file <- "myfile.txt"
cat(paste0("File not supplied.\n", "Usage: ./program F=", file))
Check this out.
Exponential is worse than polynomial.
O(n^2) falls into the quadratic category, which is a type of polynomial (the special case of the exponent being equal to 2) and better than exponential.
Exponential is much worse than polynomial. Look at how the functions grow
n = 10 | 100 | 1000
n^2 = 100 | 10000 | 1000000
k^n = k^10 | k^100 | k^1000
k^1000 is exceptionally huge unless k is smaller than something like 1.1. Like, something like every particle in the universe would have to do 100 billion billion billion operations per second for trillions of billions of billions of years to get that done.
I didn't calculate it out, but ITS THAT BIG.
Swift 4 Dictionary
extension.
extension Dictionary {
var jsonStringRepresentation: String? {
guard let theJSONData = try? JSONSerialization.data(withJSONObject: self,
options: [.prettyPrinted]) else {
return nil
}
return String(data: theJSONData, encoding: .ascii)
}
}
Try this
{% if var in ['foo', 'bar', 'beer'] %}
...
{% endif %}
In your class you should have:
public void paint(Graphics g){
g.drawLine(x1, y1, x2, y2);
}
Then in code if there is needed you will change x1, y1, x2, y2 and call repaint();
.
This will surely work .

The JPA 2.0 Specification states that:
- The entity class must have a no-arg constructor. It may have other constructors as well. The no-arg constructor must be public or protected.
- The entity class must a be top-level class. An enum or interface must not be designated as an entity.
- The entity class must not be final. No methods or persistent instance variables of the entity class may be final.
- If an entity instance is to be passed by value as a detached object (e.g., through a remote interface), the entity class must implement the Serializable interface.
- Both abstract and concrete classes can be entities. Entities may extend non-entity classes as well as entity classes, and non-entity classes may extend entity classes.
The specification contains no requirements about the implementation of equals and hashCode methods for entities, only for primary key classes and map keys as far as I know.
An example that uses RecursiveDirectoryIterator class, it's a convenient way to iterate recursively over filesystem.
$output = array();
foreach( new RecursiveIteratorIterator(
new RecursiveDirectoryIterator( 'path', FilesystemIterator::SKIP_DOTS | FilesystemIterator::UNIX_PATHS ) ) as $value ) {
if ( $value->isFile() ) {
$output[] = array( $value->getMTime(), $value->getRealPath() );
}
}
usort ( $output, function( $a, $b ) {
return $a[0] > $b[0];
});
As commented, just in case the link I posted there broke, try this:
Add a Name(any valid name) in Excel's Name Manager under Formula tab in the Ribbon.
Then assign a formula using GET.CELL function.
=GET.CELL(63,INDIRECT("rc",FALSE))
63 stands for backcolor.
Let's say we name it Background so in any cell with color type:
=Background
Result:
Notice that Cells A2, A3 and A4 returns 3, 4, and 5 respectively which equates to the cells background color index. HTH.
BTW, here's a link on Excel's Color Index
You can write the query as below:
SELECT * FROM Manager
WHERE managerid LIKE '\_%' escape '\'
AND managername LIKE '%\_%' escape '\';
it will solve your problem.
Assuming, as seems to be the case, ${triningIdArray}
is a server-side placeholder that is replaced with JS array-literal syntax, just lose the quotes. So:
var traingIds = ${triningIdArray};
not
var traingIds = "${triningIdArray}";
An example:
use strict;
for (1 .. 2){
# Both variables are lexically scoped to the block.
our ($o); # Belongs to 'main' package.
my ($m); # Does not belong to a package.
# The variables differ with respect to newness.
$o ++;
$m ++;
print __PACKAGE__, " >> o=$o m=$m\n"; # $m is always 1.
# The package has changed, but we still have direct,
# unqualified access to both variables, because the
# lexical scope has not changed.
package Fubb;
print __PACKAGE__, " >> o=$o m=$m\n";
}
# The our() and my() variables differ with respect to privacy.
# We can still access the variable declared with our(), provided
# that we fully qualify its name, but the variable declared
# with my() is unavailable.
print __PACKAGE__, " >> main::o=$main::o\n"; # 2
print __PACKAGE__, " >> main::m=$main::m\n"; # Undefined.
# Attempts to access the variables directly won't compile.
# print __PACKAGE__, " >> o=$o\n";
# print __PACKAGE__, " >> m=$m\n";
# Variables declared with use vars() are like those declared
# with our(): belong to a package; not private; and not new.
# However, their scoping is package-based rather than lexical.
for (1 .. 9){
use vars qw($uv);
$uv ++;
}
# Even though we are outside the lexical scope where the
# use vars() variable was declared, we have direct access
# because the package has not changed.
print __PACKAGE__, " >> uv=$uv\n";
# And we can access it from another package.
package Bubb;
print __PACKAGE__, " >> main::uv=$main::uv\n";
At my work we have our restful services on a different port number and the data resides in db2 on a pair of AS400s. We typically use the $.getJSON
AJAX method because it easily returns JSONP using the ?callback=?
without having any issues with CORS.
data ='USER=<?echo trim($USER)?>' +
'&QRYTYPE=' + $("input[name=QRYTYPE]:checked").val();
//Call the REST program/method returns: JSONP
$.getJSON( "http://www.stackoverflow.com/rest/resttest?callback=?",data)
.done(function( json ) {
// loading...
if ($.trim(json.ERROR) != '') {
$("#error-msg").text(message).show();
}
else{
$(".error").hide();
$("#jsonp").text(json.whatever);
}
})
.fail(function( jqXHR, textStatus, error ) {
var err = textStatus + ", " + error;
alert('Unable to Connect to Server.\n Try again Later.\n Request Failed: ' + err);
});

The solution was simply to comment the lines "work_mem=256MB" and "maintenance_work_mem=$3GB" in the file postgresql.conf and try to start the postgresql service. (start -> run -> services.msc) and look for the postgresql-[version] service then right click and start.

I had these SQL behavior settings enabled on options query execution: ANSI SET IMPLICIT_TRANSACTIONS checked. On execution of your query e.g create, alter table or stored procedure, you have to COMMIT it.
Just type COMMIT and execute it F5
Using this.props.children
is the idiomatic way to pass instantiated components to a react component
const Label = props => <span>{props.children}</span>
const Tab = props => <div>{props.children}</div>
const Page = () => <Tab><Label>Foo</Label></Tab>
When you pass a component as a parameter directly, you pass it uninstantiated and instantiate it by retrieving it from the props. This is an idiomatic way of passing down component classes which will then be instantiated by the components down the tree (e.g. if a component uses custom styles on a tag, but it wants to let the consumer choose whether that tag is a div
or span
):
const Label = props => <span>{props.children}</span>
const Button = props => {
const Inner = props.inner; // Note: variable name _must_ start with a capital letter
return <button><Inner>Foo</Inner></button>
}
const Page = () => <Button inner={Label}/>
If what you want to do is to pass a children-like parameter as a prop, you can do that:
const Label = props => <span>{props.content}</span>
const Tab = props => <div>{props.content}</div>
const Page = () => <Tab content={<Label content='Foo' />} />
After all, properties in React are just regular JavaScript object properties and can hold any value - be it a string, function or a complex object.
The easiest way I found (just I use eval() to convert string gotten from input to tuple to read again for form instance or other place)
This trick works very well
#model.py
class ClassName(models.Model):
field_name = models.CharField(max_length=100)
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
if self.field_name:
self.field_name= eval(self.field_name)
#form.py
CHOICES = [('pi', 'PI'), ('ci', 'CI')]
class ClassNameForm(forms.ModelForm):
field_name = forms.MultipleChoiceField(choices=CHOICES)
class Meta:
model = ClassName
fields = ['field_name',]
You can stash
(save the changes in temporary box) then, back to master
branch HEAD.
$ git add .
$ git stash
$ git checkout master
Jump Over Commits Back and Forth:
Go to a specific commit-sha
.
$ git checkout <commit-sha>
If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.
# checkout a new branch, add, commit, push
$ git checkout -b <branch-name>
$ git add .
$ git commit -m 'Commit message'
$ git push origin HEAD # push the current branch to remote
$ git checkout master # back to master branch now
If you have changes in the specific commit and don't want to keep the changes, you can do stash
or reset
then checkout to master
(or, any other branch).
# stash
$ git add -A
$ git stash
$ git checkout master
# reset
$ git reset --hard HEAD
$ git checkout master
After checking out a specific commit if you have no uncommitted change(s) then, just back to master
or other
branch.
$ git status # see the changes
$ git checkout master
# or, shortcut
$ git checkout - # back to the previous state
put export { Home };

To limit what you run as sudo, you could run
python non_sudo_stuff.py
sudo -E python -c "import os; os.system('sudo echo 1')"
without needing to store the password. The -E
parameter passes your current user's env to the process. Note that your shell will have sudo priveleges after the second command, so use with caution!
Twitter bootstrap is meant to give a baseline functionality, and provides only basic javascript plugins that do something on screen. Any additional content or functionality, you'll have to do yourself.
<div class="btn-group">
<button class="btn dropdown-toggle" data-toggle="dropdown">Action <span class="caret"></span></button>
<ul class="dropdown-menu">
<li><a href="#" id="action-1">Action</a></li>
<li><a href="#" id="action-2">Another action</a></li>
<li><a href="#" id="action-3">Something else here</a></li>
</ul>
</div><!-- /btn-group -->
and then with jQuery
jQuery("#action-1").click(function(e){
//do something
e.preventDefault();
});
this is my way :
<script type="text/javascript">
$(document).ready(function() {
setInterval(function(){currentTime("#idTimeField")}, 500);
});
function currentTime(field) {
var now = new Date();
now = now.getHours() + ':' + now.getMinutes() + ':' + now.getSeconds();
$(field).val(now);
}
it's not maybe the best but do the work :)
in shell command:

Delete your node_modules folder and run
sudo npm install --unsafe-perm=true
You could skip all this and just put your data in a table. Then refer to the table and header and it will be completely dynamic. I know this is from 3 years ago but someone may still find this useful.
Example code:
Activesheet.Range("TableName[ColumnName]").Copy
You can also use :
activesheet.listobjects("TableName[ColumnName]").Copy
You can even use this reference system in worksheet formulas as well. Its very dynamic.
Hope this helps!
I think a more flexible option would be to wrap the Text()
with Align()
like so:
Align(
alignment: Alignment.center, // Align however you like (i.e .centerRight, centerLeft)
child: Text("My Text"),
),
Using Center()
seems to ignore TextAlign
entirely on the Text widget. It will not align TextAlign.left
or TextAlign.right
if you try, it will remain in the center.
What you want appear to want is the following, but this is NOT RECOMMENDED:
>>> for line in open('dangerous.txt'):
... exec('%s = %s' % tuple(line.split(':', 1)))
...
>>> var_a
'home'
This creates somewhat similar behavior to PHP's register_globals
and hence has the same security issues. Additionally, the use of exec
that I showed allows arbitrary code execution. Only use this if you are absolutely sure that the contents of the text file can be trusted under all circumstances.
You should really consider binding the variables not to the local scope, but to an object, and use a library that parses the file contents such that no code is executed. So: go with any of the other solutions provided here.
(Please note: I added this answer not as a solution, but as an explicit non-solution.)
In VS 2017 it is automatic. So just Add Reference
as usually.
Note that in Reference Properties
absolute path is shown, but in .vbproj/.csproj
relative is used.

Worth noting that the code you see is sent to the database as is, the queries are sent separately to prevent SQL injection. AFAIK The ? marks are placeholders that are replaced by the number params by the database, not by hibernate.
I think you don't need to update only some specific field. Just update whole data.
@Update query
It is a given query basically. No need to make some new query.
@Dao
interface MemoDao {
@Insert
suspend fun insert(memo: Memo)
@Delete
suspend fun delete(memo: Memo)
@Update
suspend fun update(memo: Memo)
}
Memo.class
@Entity
data class Memo (
@PrimaryKey(autoGenerate = true) val id: Int,
@ColumnInfo(name = "title") val title: String?,
@ColumnInfo(name = "content") val content: String?,
@ColumnInfo(name = "photo") val photo: List<ByteArray>?
)
Only thing you need to know is 'id'. For instance, if you want to update only 'title', you can reuse 'content' and 'photo' from already inserted data. In real code, use like this
val memo = Memo(id, title, content, byteArrayList)
memoViewModel.update(memo)
Amidst the information presented by git help fetch
, there is this little item:
-p, --prune
After fetching, remove any remote-tracking branches which no longer exist on the remote.
So, perhaps, git fetch -p
is what you are looking for?
EDIT: Ok, for those still debating this answer 3 years after the fact, here's a little more information on why I presented this answer...
First, the OP says they want to "remove also those local branches that were created from those remote branches [that are not any more on the remote]". This is not unambiguously possible in git
. Here's an example.
Let's say I have a repo on a central server, and it has two branches, called A
and B
. If I clone that repo to my local system, my clone will have local refs (not actual branches yet) called origin/A
and origin/B
. Now let's say I do the following:
git checkout -b A origin/A
git checkout -b Z origin/B
git checkout -b C <some hash>
The pertinent facts here are that I for some reason chose to create a branch on my local repo that has a different name than its origin, and I also have a local branch that does not (yet) exist on the origin repo.
Now let's say I remove both the A
and B
branches on the remote repo and update my local repo (git fetch
of some form), which causes my local refs origin/A
and origin/B
to disappear. Now, my local repo has three branches still, A
, Z
, and C
. None of these have a corresponding branch on the remote repo. Two of them were "created from ... remote branches", but even if I know that there used to be a branch called B
on the origin, I have no way to know that Z
was created from B
, because it was renamed in the process, probably for a good reason. So, really, without some external process recording branch origin metadata, or a human who knows the history, it is impossible to tell which of the three branches, if any, the OP is targeting for removal. Without some external information that git
does not automatically maintain for you, git fetch -p
is about as close as you can get, and any automatic method for literally attempting what the OP asked runs the risk of either deleting too many branches, or missing some that the OP would otherwise want deleted.
There are other scenarios, as well, such as if I create three separate branches off origin/A
to test three different approaches to something, and then origin/A
goes away. Now I have three branches, which obviously can't all match name-wise, but they were created from origin/A
, and so a literal interpretation of the OPs question would require removing all three. However, that may not be desirable, if you could even find a reliable way to match them...
Writing an updated answer since most of the already present answers are obsolete as of now.
Versions earlier than Docker 19.03
used to require nvidia-docker2
and the --runtime=nvidia
flag.
Since Docker 19.03
, you need to install nvidia-container-toolkit
package and then use the --gpus all
flag.
So, here are the basics,
Package Installation
Install the nvidia-container-toolkit
package as per official documentation at Github.
For Redhat based OSes, execute the following set of commands:
$ distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
$ curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.repo | sudo tee /etc/yum.repos.d/nvidia-docker.repo
$ sudo yum install -y nvidia-container-toolkit
$ sudo systemctl restart docker
For Debian based OSes, execute the following set of commands:
# Add the package repositories
$ distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
$ curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
$ curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
$ sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit
$ sudo systemctl restart docker
Running the docker with GPU support
docker run --name my_all_gpu_container --gpus all -t nvidia/cuda
Please note, the flag --gpus all
is used to assign all available gpus to the docker container.
To assign specific gpu to the docker container (in case of multiple GPUs available in your machine)
docker run --name my_first_gpu_container --gpus device=0 nvidia/cuda
Or
docker run --name my_first_gpu_container --gpus '"device=0"' nvidia/cuda
Open Package Manager Console
Reinstall all packages in ALL PROJECTS of the current solution:
Update-Package -Reinstall
Reinstall all packages in SPECIFIC PROJECT of the current solution (Thanks to unarity and ashes999):
Update-Package -ProjectName 'YourProjectNameGoesHere' -Reinstall
Try os.chdir
os.chdir(path)
Change the current working directory to path. Availability: Unix, Windows.
I faced similar issue due to local vs remote referencing
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.3/angular.js"></script>
<script src="lib/js/ui-grid/3.0.7/ui-grid.js"></script>
As ui-grid.js is dependent on angular.js, ui-grid requires angular.js by the time its loaded. But in the above case, ui-grid.js [locally saved reference file] is loaded before angularjs was loaded [from internet],
The problem was solved if I had both angular.js and ui-grid referenced locally and as well declaring angular.js before ui-grid
<script src="lib/js/angularjs/1.4.3/angular.js"></script>
<script src="lib/js/ui-grid/3.0.7/ui-grid.js"></script>
select to_char(to_date('1/21/2000','mm/dd/yyyy'),'dd-mm-yyyy') from dual
tr
can be more concise for removing characters than sed
or awk
, especially when you want to remove different characters from a string.
Removing double quotes:
echo '"Hi"' | tr -d \"
# Produces Hi without quotes
Removing different kinds of brackets:
echo '[{Hi}]' | tr -d {}[]
# Produces Hi without brackets
-d
stands for "delete".
Not so hard:
#include <thread>
void Test::runMultiThread()
{
std::thread t1(&Test::calculate, this, 0, 10);
std::thread t2(&Test::calculate, this, 11, 20);
t1.join();
t2.join();
}
If the result of the computation is still needed, use a future instead:
#include <future>
void Test::runMultiThread()
{
auto f1 = std::async(&Test::calculate, this, 0, 10);
auto f2 = std::async(&Test::calculate, this, 11, 20);
auto res1 = f1.get();
auto res2 = f2.get();
}
This is not an answer to the original question. But, as an original question is not a real-world problem it should not be a problem. I tried to explain to a friend what are promises in JavaScript and the difference between promise and callback.
Code below serves as an explanation:
//very basic callback example using setTimeout
//function a is asynchronous function
//function b used as a callback
function a (callback){
setTimeout (function(){
console.log ('using callback:');
let mockResponseData = '{"data": "something for callback"}';
if (callback){
callback (mockResponseData);
}
}, 2000);
}
function b (dataJson) {
let dataObject = JSON.parse (dataJson);
console.log (dataObject.data);
}
a (b);
//rewriting above code using Promise
//function c is asynchronous function
function c () {
return new Promise(function (resolve, reject) {
setTimeout (function(){
console.log ('using promise:');
let mockResponseData = '{"data": "something for promise"}';
resolve(mockResponseData);
}, 2000);
});
}
c().then (b);
Or you could try:
cloc-git
You can use this shell script to count the number of lines in a remote Git repository with one command:
#!/usr/bin/env bash
git clone --depth 1 "$1" temp-linecount-repo &&
printf "('temp-linecount-repo' will be deleted automatically)\n\n\n" &&
cloc temp-linecount-repo &&
rm -rf temp-linecount-repo
This script requires CLOC (“Count Lines of Code”) to be installed. cloc
can probably be installed with your package manager – for example, brew install cloc
with Homebrew. There is also a docker image published under mribeiro/cloc
.
You can install the script by saving its code to a file cloc-git
, running chmod +x cloc-git
, and then moving the file to a folder in your $PATH
such as /usr/local/bin
.
The script takes one argument, which is any URL that git clone
will accept. Examples are https://github.com/evalEmpire/perl5i.git
(HTTPS) or [email protected]:evalEmpire/perl5i.git
(SSH). You can get this URL from any GitHub project page by clicking “Clone or download”.
Example output:
$ cloc-git https://github.com/evalEmpire/perl5i.git

If you don’t want to bother saving and installing the shell script, you can run the commands manually. An example:
$ git clone --depth 1 https://github.com/evalEmpire/perl5i.git
$ cloc perl5i
$ rm -rf perl5i
If you want the results to match GitHub’s language percentages exactly, you can try installing Linguist instead of CLOC. According to its README, you need to gem install linguist
and then run linguist
. I couldn’t get it to work (issue #2223).
The correct answer using JodaTime is:
public int getAge() {
Years years = Years.yearsBetween(new LocalDate(getBirthDate()), new LocalDate());
return years.getYears();
}
You could even shorten it into one line if you like. I copied the idea from BrianAgnew's answer, but I believe this is more correct as you see from the comments there (and it answers the question exactly).
For auto commit off then use the below command for sure. Set below in my.cnf
file:
[mysqld]
autocommit=0
You need to use the URL for the link, such as this:
NSURL *path = [[NSBundle mainBundle] URLForResource:@"imagename" withExtension:@"jpg"];
It will give you a proper URL ref.
I was facing following error with code (nodejs 0.10.13), provided by ampersand:
origin is not allowed by access-control-allow-origin
Issue was resolved changing
response.writeHead(200, {"Content-Type": "text/plain"});
to
response.writeHead(200, {
'Content-Type': 'text/html',
'Access-Control-Allow-Origin' : '*'});
A cleaner alternative would be to use a Dictionary
to handle parameters. They are key-value pairs after all.
private static readonly HttpClient httpclient;
static MyClassName()
{
// HttpClient is intended to be instantiated once and re-used throughout the life of an application.
// Instantiating an HttpClient class for every request will exhaust the number of sockets available under heavy loads.
// This will result in SocketException errors.
// https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=netframework-4.7.1
httpclient = new HttpClient();
}
var url = "http://myserver/method";
var parameters = new Dictionary<string, string> { { "param1", "1" }, { "param2", "2" } };
var encodedContent = new FormUrlEncodedContent (parameters);
var response = await httpclient.PostAsync (url, encodedContent).ConfigureAwait (false);
if (response.StatusCode == HttpStatusCode.OK) {
// Do something with response. Example get content:
// var responseContent = await response.Content.ReadAsStringAsync ().ConfigureAwait (false);
}
Also dont forget to Dispose()
httpclient, if you dont use the keyword using
As stated in the Remarks section of the HttpClient class in the Microsoft docs, HttpClient should be instantiated once and re-used.
Edit:
You may want to look into response.EnsureSuccessStatusCode();
instead of if (response.StatusCode == HttpStatusCode.OK)
.
You may want to keep your httpclient and dont Dispose()
it. See: Do HttpClient and HttpClientHandler have to be disposed?
Edit:
Do not worry about using .ConfigureAwait(false) in .NET Core. For more details look at https://blog.stephencleary.com/2017/03/aspnetcore-synchronization-context.html

To get the functionality up and running:
adb.exe
(might need to start and stop ADB using adb kill-server
and adb start-server
)about:inspect
in Chrome on desktop, ensuring a Chrome browser is open on your deviceFollowing the above steps I got the RSA key fingerprint prompt to accept then I saw my device in Chrome.
Definitely not as easy as I thought it would have been but at least it now works.
Update 24 February 2016
So I updated to Windows 10 and now have a Samsung Galaxy S5, devices running Chrome v48.0.2564.116 m and v48.0.2564.95 respectively. Followed the steps from the Google docs and...it didn't work again, no RSA key prompt. So I began to follow my steps as above and thought there had to be a faster way as the Android SDK was over 1GB download.
This time I tried:
C:\Program Files (x86)\Minimal ADB and Fastboot\
adb devices
(alternatively I could have run adb start-server
but the prior gives a more informational response)Now, with Chrome open on my phone and chrome://inspect/
open on my desktop I can see the inspect options.
Next problem: I need to repeat the same steps each time I reboot Windows. To solve that issue:
"C:\Program Files (x86)\Minimal ADB and Fastboot\adb" devices
adb.bat
in the Windows Startup folder located at C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp
Note that the file does NOT need to be called adb.bat as long as it is a .bat file. The command you copied into the file has the default install path which you may need to alter for your set up.
Now I have the Chrome Inspect feature working when I need it.

This problem is due to the https protocol, which is why the other solution works (by switching to the non-secure protocol).
For me, the best solution was to compile the latest version of node, which includes npm
apt-get purge nodejs npm
git clone https://github.com/nodejs/node ~/local/node
cd ~/local/node
./configure
make
make install
try this function
function summary($str, $limit=100, $strip = false) {
$str = ($strip == true)?strip_tags($str):$str;
if (strlen ($str) > $limit) {
$str = substr ($str, 0, $limit - 3);
return (substr ($str, 0, strrpos ($str, ' ')).'...');
}
return trim($str);

I found that ctrl + w to the window you want to close, then just do :q. This works for me.
As others pointed out, it is not good practice to initialize data on views. Initializing data on Controllers, however, is recommended. (see http://docs.angularjs.org/guide/controller)
So you can write
<input name="card[description]" ng-model="card.description">
and
$scope.card = { description: 'Visa-4242' };
$http.get('/getCardInfo.php', function(data) {
$scope.card = data;
});
This way the views do not contain data, and the controller initializes the value while the real values are being loaded.
I always use this code... Use this code
String clientScriptName = "ButtonClickScript";
Type clientScriptType = this.GetType ();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager clientScript = Page.ClientScript;
// Check to see if the client script is already registered.
if (!clientScript.IsClientScriptBlockRegistered (clientScriptType, clientScriptName))
{
StringBuilder sb = new StringBuilder ();
sb.Append ("<script type='text/javascript'>");
sb.Append ("window.open(' " + url + "')"); //URL = where you want to redirect.
sb.Append ("</script>");
clientScript.RegisterClientScriptBlock (clientScriptType, clientScriptName, sb.ToString ());
}
For me was php version from mac instead of MAMP, PATH variable on .bash_profile was wrong. I just prepend the MAMP PHP bin folder to the $PATH env variable. For me was:
/Applications/mampstack-7.1.21-0/php/bin
In terminal run vim ~/.bash_profile
to open ~/.bash_profile
Type i to be able to edit the file, add the bin directory as PATH variable on the top to the file:
export PATH="/Applications/mampstack-7.1.21-0/php/bin/:$PATH"
Hit ESC
, Type :wq
, and hit Enter
source ~/.bash_profile
which php
, output should be the path to MAMP PHP install.Turns out the binding of style to a string doesn't work. The solution would be to bind the background of the style.
<div class="circle" [style.background]="color">
If you're using Vim in visual mode, the standard cut and paste keys also apply, at least with Windows.

You must have imported multiple stylesheets. try to remove one and try again
DOMContentLoaded
==window.onDomReady()
Load
==window.onLoad()
A page can't be manipulated safely until the document is "ready." jQuery detects this state of readiness for you. Code included inside
$(document).ready()
will only run once the page Document Object Model (DOM) is ready for JavaScript code to execute. Code included inside$(window).load(function() { ... })
will run once the entire page (images or iframes), not just the DOM, is ready.
You could take a look at the DateTimeFormat property which contains the culture specific formats.
Apparently running sudo chmod -R a+rw
on your home folder causes this to happen as well.
Use assertNotNull(obj)
. assert
means must be
.
In windows Appliation we use like this
DDLChangeImpact.SelectedIndex = DDLChangeImpact.FindStringExact(ds.Tables[0].Rows[0]["tmchgimp"].ToString());

@doug & FS.'s answer are very good solutions. I want to share the solution for iteration on pandas.dataframe.
import pandas as pd
df=pd.DataFrame([[1, 2], [3, 4], [4, 3], [2, 3]])
fig = plt.figure(figsize=(14,8))
for i in df.columns:
ax=plt.subplot(2,1,i+1)
df[[i]].plot(ax=ax)
print(i)
plt.show()
Often times we are interested in calculating the full significant digits, but for the visual aesthetics, we may want to see only few decimal point when we display the dataframe.
In jupyter-notebook, pandas can utilize the html formatting taking advantage of the method called style
.
For the case of just seeing two significant digits of some columns, we can use this code snippet:

The window object in JavaScript on iOS devices has an orientation property that can be used to determine the rotation of the device. The following shows the values window.orientation for iOS devices (e.g. iPhone, iPad, iPod) at different orientations.
This solution also works for android devices as well. I checked in android native browser (Internet browser) and in the Chrome browser, even in the old versions of it.
function readDeviceOrientation() {
if (Math.abs(window.orientation) === 90) {
// Landscape
} else {
// Portrait
}
}
I recommend using the incredible requests
module.
http://docs.python-requests.org/en/v0.10.7/user/quickstart/#custom-headers
url = 'https://api.github.com/some/endpoint'
payload = {'some': 'data'}
headers = {'content-type': 'application/json'}
response = requests.post(url, data=json.dumps(payload), headers=headers)
For ease of re-use throughout your application a static class may help.
public static class StaticRandom
{
private static int seed;
private static ThreadLocal<Random> threadLocal = new ThreadLocal<Random>
(() => new Random(Interlocked.Increment(ref seed)));
static StaticRandom()
{
seed = Environment.TickCount;
}
public static Random Instance { get { return threadLocal.Value; } }
}
You can use then use static random instance with code such as
StaticRandom.Instance.Next(1, 100);
As far as I know, there is no standard way to achieve this with only CSS, although I think there should be. Mozilla browsers used to support fixed headers with a scrolling body, but they've removed it in the last few years.
After researching this a bit, including finding this posting, a friend just developed this solution for me; it uses Javascript but no canned libraries, and the only requirement for the HTML markup is that the table have an id name. Then, at window.onload, to call one Javascript function for each table giving the id, height, and width. If Javascript is disabled at the browser, the whole table is displayed according to its original markup. If Javascript is enabled, the table is fit into the specified height and width, and tbody scrolls, and if thead and tfoot exist, they are fixed at top and bottom.
What does res.render do and what does the html file look like?
res.render()
function compiles your template (please don't use ejs), inserts locals there, and creates html output out of those two things.
Answering Edit 2 part.
// here you set that all templates are located in `/views` directory
app.set('views', __dirname + '/views');
// here you set that you're using `ejs` template engine, and the
// default extension is `ejs`
app.set('view engine', 'ejs');
// here you render `orders` template
response.render("orders", {orders: orders_json});
So, the template path is views/
(first part) + orders
(second part) + .ejs
(third part) === views/orders.ejs
Anyway, express.js documentation is good for what it does. It is API reference, not a "how to use node.js" book.
Another example of Apache Common StringSubstitutor for simple named placeholder.
String template = "Welcome to {theWorld}. My name is {myName}.";
Map<String, String> values = new HashMap<>();
values.put("theWorld", "Stackoverflow");
values.put("myName", "Thanos");
String message = StringSubstitutor.replace(template, values, "{", "}");
System.out.println(message);
// Welcome to Stackoverflow. My name is Thanos.
