The problem seems to be that you have misunderstood how async/await work with Entity Framework.
So, let's look at this code:
public IQueryable<URL> GetAllUrls()
{
return context.Urls.AsQueryable();
}
and example of it usage:
repo.GetAllUrls().Where(u => <condition>).Take(10).ToList()
What happens there?
IQueryable
object (not accessing database yet) using repo.GetAllUrls()
IQueryable
object with specified condition using .Where(u => <condition>
IQueryable
object with specified paging limit using .Take(10)
.ToList()
. Our IQueryable
object is compiled to sql (like select top 10 * from Urls where <condition>
). And database can use indexes, sql server send you only 10 objects from your database (not all billion urls stored in database)Okay, let's look at first code:
public async Task<IQueryable<URL>> GetAllUrlsAsync()
{
var urls = await context.Urls.ToListAsync();
return urls.AsQueryable();
}
With the same example of usage we got:
await context.Urls.ToListAsync();
.Why async/await is preferred to use? Let's look at this code:
var stuff1 = repo.GetStuff1ForUser(userId);
var stuff2 = repo.GetStuff2ForUser(userId);
return View(new Model(stuff1, stuff2));
What happens here?
var stuff1 = ...
userId
var stuff2 = ...
userId
So let's look to an async version of it:
var stuff1Task = repo.GetStuff1ForUserAsync(userId);
var stuff2Task = repo.GetStuff2ForUserAsync(userId);
await Task.WhenAll(stuff1Task, stuff2Task);
return View(new Model(stuff1Task.Result, stuff2Task.Result));
What happens here?
So good code here:
using System.Data.Entity;
public IQueryable<URL> GetAllUrls()
{
return context.Urls.AsQueryable();
}
public async Task<List<URL>> GetAllUrlsByUser(int userId) {
return await GetAllUrls().Where(u => u.User.Id == userId).ToListAsync();
}
Note, than you must add using System.Data.Entity
in order to use method ToListAsync()
for IQueryable.
Note, that if you don't need filtering and paging and stuff, you don't need to work with IQueryable
. You can just use await context.Urls.ToListAsync()
and work with materialized List<Url>
.
You cannot use properties that are not mapped to a database column in a Where
expression. You must build the expression based on mapped properties, like:
var date = DateTime.Now.AddYears(-from);
result = result.Where(p => date >= p.DOB);
// you don't need `AsQueryable()` here because result is an `IQueryable` anyway
As a replacement for your not mapped Age
property you can extract this expression into a static method like so:
public class clsProfileDate
{
// ...
public DateTime DOB { get; set; } // property mapped to DB table column
public static Expression<Func<clsProfileDate, bool>> IsOlderThan(int age)
{
var date = DateTime.Now.AddYears(-age);
return p => date >= p.DOB;
}
}
And then use it this way:
result = result.Where(clsProfileDate.IsOlderThan(from));
I had been using the method in Jon Skeet's answer, but another one occurred to me using Concat
. The Concat
method performed slightly better in a limited test, but it's a hassle and I'll probably just stick with Contains
, or maybe I'll write a helper method to do this for me. Either way, here's another option if anyone is interested:
// Given an array of id's
var ids = new Guid[] { ... };
// and a DataContext
var dc = new MyDataContext();
// start the queryable
var query = (
from thing in dc.Things
where thing.Id == ids[ 0 ]
select thing
);
// then, for each other id
for( var i = 1; i < ids.Count(); i++ ) {
// select that thing and concat to queryable
query.Concat(
from thing in dc.Things
where thing.Id == ids[ i ]
select thing
);
}
This was not remotely scientific. I imagine your database structure and the number of IDs involved in the list would have a significant impact.
I set up a test where I did 100 trials each of Concat
and Contains
where each trial involved selecting 25 rows specified by a randomized list of primary keys. I've run this about a dozen times, and most times the Concat
method comes out 5 - 10% faster, although one time the Contains
method won by just a smidgen.
You need a split function:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
Create Function [dbo].[udf_Split]
(
@DelimitedList nvarchar(max)
, @Delimiter nvarchar(2) = ','
)
RETURNS TABLE
AS
RETURN
(
With CorrectedList As
(
Select Case When Left(@DelimitedList, Len(@Delimiter)) <> @Delimiter Then @Delimiter Else '' End
+ @DelimitedList
+ Case When Right(@DelimitedList, Len(@Delimiter)) <> @Delimiter Then @Delimiter Else '' End
As List
, Len(@Delimiter) As DelimiterLen
)
, Numbers As
(
Select TOP( Coalesce(DataLength(@DelimitedList)/2,0) ) Row_Number() Over ( Order By c1.object_id ) As Value
From sys.columns As c1
Cross Join sys.columns As c2
)
Select CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen As Position
, Substring (
CL.List
, CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen
, CharIndex(@Delimiter, CL.list, N.Value + 1)
- ( CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen )
) As Value
From CorrectedList As CL
Cross Join Numbers As N
Where N.Value <= DataLength(CL.List) / 2
And Substring(CL.List, N.Value, CL.DelimiterLen) = @Delimiter
)
With your split function, you would then use Cross Apply to get the data:
Select T.Col1, T.Col2
, Substring( Z.Value, 1, Charindex(' = ', Z.Value) - 1 ) As AttributeName
, Substring( Z.Value, Charindex(' = ', Z.Value) + 1, Len(Z.Value) ) As Value
From Table01 As T
Cross Apply dbo.udf_Split( T.Col3, '|' ) As Z
System.TypeInitializationException
happens when the code that gets executed during the process of loading the type throws an exception.
When .NET loads the type, it must prepare all its static fields before the first time that you use the type. Sometimes, initialization requires running code. It is when that code fails that you get a System.TypeInitializationException
.
In your specific case, the following three static fields run some code:
private static string s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
private static string s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");
private static string s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
Note that s_bstCommonAppData
depends on s_commonAppData
, but it is declared ahead of its dependency. Therefore, the value of s_commonAppData
is null
at the time that the Path.Combine
is called, resulting in ArgumentNullException
. Same goes for the s_bstUserDataDir
and s_bstCommonAppData
: they are declared in reverse order to the desired order of initialization.
Re-order the lines to fix this problem:
private static string s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
private static string s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
private static string s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");
Check this fiddle. You are going to need to take a look at using border-collapse and border-spacing. There are some quirks for IE (as usual). This is based on an answer to this question.
table.test td {
background-color: lime;
margin: 12px 12px 12px 12px;
padding: 12px 12px 12px 12px;
}
table.test {
border-collapse: separate;
border-spacing: 10px;
*border-collapse: expression('separate', cellSpacing='10px');
}
_x000D_
<table class="test">

Have a look at entry points too. You will be able to use multiple CMD https://docs.docker.com/engine/reference/builder/#/entrypoint
You could use ROW_NUMBER()
with a ORDER BY
clause in sub-query and use this column in replacement of TOP N
. This can be explained step-by-step.
See the below table which have two columns NAME
and DT_CREATED
.
If you need to take only the first two dates irrespective of NAME
, you could use the below query. The logic has been written inside query
-- The number of records can be specified in WHERE clause
SELECT RNO,NAME,DT_CREATED
FROM
(
-- Generates numbers in a column in sequence in the order of date
SELECT ROW_NUMBER() OVER (ORDER BY DT_CREATED) AS RNO,
NAME,DT_CREATED
FROM DEMOTOP
)TAB
WHERE RNO<3;
RESULT
In some situations, we need to select TOP N
results respective to each NAME
. In such case we can use PARTITION BY
with an ORDER BY
clause in sub-query. Refer the below query.
-- The number of records can be specified in WHERE clause
SELECT RNO,NAME,DT_CREATED
FROM
(
--Generates numbers in a column in sequence in the order of date for each NAME
SELECT ROW_NUMBER() OVER (PARTITION BY NAME ORDER BY DT_CREATED) AS RNO,
NAME,DT_CREATED
FROM DEMOTOP
)TAB
WHERE RNO<3;
RESULT
The Java 8 streaming api offers an elegant alternative:
public static void main(String[] args) {
double avg = Arrays.stream(new int[]{1,3,2,5,8}).average().getAsDouble();
System.out.println("avg: " + avg);
}
I found this on another forum. Works like a champ.

Well I'm not a pro in C++, but learnt it in school. I am using this algo for past 1 year to store different random values in a 1D array, but this will also work in 2D array after some changes. Any suggestions about the code are welcome.
In JavaScript 1.8.5, Object.getOwnPropertyNames
returns an array of all properties found directly upon a given object.
Object.getOwnPropertyNames ( obj )
and another method Object.keys
, which returns an array containing the names of all of the given object's own enumerable properties.
Object.keys( obj )
I used forEach
to list values and keys in obj, same as for (var key in obj) ..
Object.keys(obj).forEach(function (key) {
console.log( key , obj[key] );
});
This all are new features in ECMAScript , the mothods getOwnPropertyNames
, keys
won't supports old browser's.
To prohibit declarations of variables with the same name.
e.g.
int i = 0, goto;
EDIT: This answer (and most of the others) are obsolete; see Devpool's answer instead.
Originally, there were no config options to make "git diff --ignore-submodules
" and "git status --ignore-submodules
" the global default (but see also Setting git default flags on commands). An alternative is to set a default ignore
config option on each individual submodule you want to ignore (for both git diff
and git status
), either in the .git/config
file (local only) or .gitmodules
(will be versioned by git). For example:
[submodule "foobar"]
url = [email protected]:foo/bar.git
ignore = untracked
ignore = untracked
to ignore just untracked files, ignore = dirty
to also ignore modified files, and ignore = all
to ignore also commits.
There's apparently no way to wildcard it for all submodules.
Since both pip
nor python
commands are not installed along Python in Windows, you will need to use the Windows alternative py
, which is included by default when you installed Python. Then you have the option to specify a general or specific version number after the py
command.
C:\> py -m pip install pandas %= one of Python on the system =%
C:\> py -2 -m pip install pandas %= one of Python 2 on the system =%
C:\> py -2.7 -m pip install pandas %= only for Python 2.7 =%
C:\> py -3 -m pip install pandas %= one of Python 3 on the system =%
C:\> py -3.6 -m pip install pandas %= only for Python 3.6 =%
Alternatively, in order to get pip
to work without py -m
part, you will need to add pip to the PATH environment variable.
C:\> setx PATH "%PATH%;C:\<path\to\python\folder>\Scripts"
Now you can run the following command as expected.
C:\> pip install pandas
connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed
This is caused by your SSL certificate is unable to verify the host server. You can add pypi.python.org to the trusted host or specify an alternative SSL certificate. For more information, please see this post. (Thanks to Anuj Varshney for suggesting this)
C:\> py -m pip install --trusted-host pypi.python.org pip pandas
PermissionError: [WinError 5] Access is denied
This is a caused by when you don't permission to modify the Python site-package folders. You can avoid this with one of the following methods:
Run Windows Command Prompt as administrator (thanks to DataGirl's suggestion) by:
cmd.exe
in the search boxRun pip in user mode by adding --user
option when installing with pip. Which typically install the package to the local %APPDATA% Python folder.
C:\> py -m pip install --user pandas
C:\> py -m venv c:\path\to\new\venv
C:\> <path\to\the\new\venv>\Scripts\activate.bat
A very useful git ignore command comes with the awesome tj/git-extras.
Here are a few usage examples:
git ignore
git ignore "*.log"
git ignore-io -a rails
git-extras provides many more useful commands. Definitely worth trying out.
Or you could use a regular expression:
alert(href.replace(/.*\//, ''));
I will just add a blank ("") to the end of the variable and do the comparison. Something like below should work even when that variable is null. You can also trim the variable just in case of spaces.
If provider & "" <> "" Then
url = url & "&provider=" & provider
End if
SUMMARY: In ASP.NET, every Web page derives from the System.Web.UI.Page class. The Page class aggregates an instance of the HttpSession object for session data. The Page class exposes different events and methods for customization. In particular, the OnInit method is used to set the initialize state of the Page object. If the request does not have the Session cookie, a new Session cookie will be issued to the requester.
EDIT:
Session: A Concept for Beginners
SUMMARY: Session is created when user sends a first request to the server for any page in the web application, the application creates the Session and sends the Session ID back to the user with the response and is stored in the client machine as a small cookie. So ideally the "machine that has disabled the cookies, session information will not be stored".
I wanted to see the hover state on my Bootstrap tooltips. Forcing the the :hover state in Chrome dev Tools did not create the required output, yet triggering the mouseenter event via console did the trick in Chrome. If jQuery exists on the page you can run:
$('.YOUR-TOOL-TIP-CLASS').trigger('mouseenter');
While the other answers got it right when it comes to add comments, in my case only the following worked.

I answered a virtually identical question just the other day: Save CSV files into mysql database
MySQL has a feature LOAD DATA INFILE
, which allows it to import a CSV file directly in a single SQL query, without needing it to be processed in a loop via your PHP program at all.
Simple example:
<?php
$query = <<<eof
LOAD DATA INFILE '$fileName'
INTO TABLE tableName
FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
(field1,field2,field3,etc)
eof;
$db->query($query);
?>
It's as simple as that.
No loops, no fuss. And much much quicker than parsing it in PHP.
MySQL manual page here: http://dev.mysql.com/doc/refman/5.1/en/load-data.html
Hope that helps
EDIT (02 Jan 2012):
I created a small open source Android Library Project that streamlines this process, while also providing a built-in file explorer (in case the user does not have one present). It's extremely simple to use, requiring only a few lines of code.
You can find it at GitHub: aFileChooser.
ORIGINAL
If you want the user to be able to choose any file in the system, you will need to include your own file manager, or advise the user to download one. I believe the best you can do is look for "openable" content in an Intent.createChooser()
like this:
private static final int FILE_SELECT_CODE = 0;
private void showFileChooser() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult(
Intent.createChooser(intent, "Select a File to Upload"),
FILE_SELECT_CODE);
} catch (android.content.ActivityNotFoundException ex) {
// Potentially direct the user to the Market with a Dialog
Toast.makeText(this, "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}
}
You would then listen for the selected file's Uri
in onActivityResult()
like so:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case FILE_SELECT_CODE:
if (resultCode == RESULT_OK) {
// Get the Uri of the selected file
Uri uri = data.getData();
Log.d(TAG, "File Uri: " + uri.toString());
// Get the path
String path = FileUtils.getPath(this, uri);
Log.d(TAG, "File Path: " + path);
// Get the file instance
// File file = new File(path);
// Initiate the upload
}
break;
}
super.onActivityResult(requestCode, resultCode, data);
}
The getPath()
method in my FileUtils.java
is:
public static String getPath(Context context, Uri uri) throws URISyntaxException {
if ("content".equalsIgnoreCase(uri.getScheme())) {
String[] projection = { "_data" };
Cursor cursor = null;
try {
cursor = context.getContentResolver().query(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow("_data");
if (cursor.moveToFirst()) {
return cursor.getString(column_index);
}
} catch (Exception e) {
// Eat it
}
}
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
}
This threw me for a long time too. The first thing I'd verify is that you're not reloading the page by clicking the refresh button, that will always issue a conditional request for resources and will return 304s for many of the page elements. Instead go up to the url bar select the page and hit enter as if you had just typed in the same URL again, that will give you a better indicator of what's being cached properly. This article does a great job explaining the difference between conditional and unconditional requests and how the refresh button affects them: http://blogs.msdn.com/b/ieinternals/archive/2010/07/08/technical-information-about-conditional-http-requests-and-the-refresh-button.aspx
If you can use java streams, you can try the following:
Random randomizeTimestamp = new Random();
Long min = ZonedDateTime.parse("2018-01-01T00:00:00.000Z").toInstant().toEpochMilli();
Long max = ZonedDateTime.parse("2019-01-01T00:00:00.000Z").toInstant().toEpochMilli();
randomizeTimestamp.longs(generatedEventListSize, min, max).forEach(timestamp -> {
System.out.println(timestamp);
});
This will generate numbers in the given range for longs.

Based in the response of basarat, I give here a little more information how to run this in Visual Studio 2013.
[UPDATE]
If you update your Visual Studio to a new version of Typescript as 1.0.x you don't see the last version here. To see the last version:
NOTE: Typescript 1.3 install in directory 1.1, for that it is important to run the command to know the last version that you have installed.
NOTE: It is possible that you have installed a version 1.3 and your code use 1.0.3. To avoid this if you have your Typescript in a separate(s) project(s) unload the project and see if the Typescript tag:
<TypeScriptToolsVersion>1.1</TypeScriptToolsVersion>
is set to 1.1.
[UPDATE 2]
TypeScript version 1.4, 1.5 .. 1.7 install in 1.4, 1.5... 1.7 directories. they are not problem to found version. if you have typescript in separate project and you migrate from a previous typescript your project continue to use the old version. to solve this:
unload the project file and change the typescript version to 1.x at:
<TypeScriptToolsVersion>1.x</TypeScriptToolsVersion>
If you installed the typescript using the visual studio installer file, the path to the new typescript compiler should be automatically updated to point to 1.x directory. If you have problem, review that you environment variable Path include
C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.x\
SUGGESTION TO MICROSOFT :-) Because Typescript run side by side with other version, maybe is good to have in the project properties have a combo box to select the typescript compiler (similar to select the net version)

If a class, or anything derived from it, might hold the last live reference to an object with a finalizer, then either GC.SuppressFinalize(this)
or GC.KeepAlive(this)
should be called on the object after any operation that might be adversely affected by that finalizer, thus ensuring that the finalizer won't run until after that operation is complete.
The cost of GC.KeepAlive()
and GC.SuppressFinalize(this)
are essentially the same in any class that doesn't have a finalizer, and classes that do have finalizers should generally call GC.SuppressFinalize(this)
, so using the latter function as the last step of Dispose()
may not always be necessary, but it won't be wrong.
Easier still you can just do
for i in {00001..99999}; do
echo $i
done
I think you need to use for example:
aws ecs list-container-instances --cluster default --region us-east-1

Add @ResponseBody

This is kind of old, but anyway, I hope you'll appreciate the link that I am about to type as I appreciated it when I came across it earlier this year.
Here it is. I should quote the explanation that is always in my mind when I have to grasp some nasty typedefs:
In variable declarations, the introduced names are instances of the corresponding types. [...] However, when the
typedef
keyword precedes the declaration, the introduced names are aliases of the corresponding types
As many people previously said, there is no need to use typedefs declaring enums in C++. But that's the explanation of the typedef's syntax! I hope it helps (Probably not OP, since it's been almost 10 years, but anyone that is struggling to understand these kind of things).
Adressing the problem in the current correct answer "clicking the field shows the onscreen keyboard instead of the datepicker":
The problem is caused by the Browser behaving according to the type of input when clicking (=text). Therefore it is necessary to stop from focussing on the input element (blur) and then restart focus programmatically on the input element which was defined as type=date by JS in the first step. Keyboard displays in phonenumber-mode.
<input placeholder="Date" type="text" onfocus="this.type='date';
this.setAttribute('onfocus','');this.blur();this.focus();">
Use also this way to represent image in base64 encode format...
find PHP function file_get_content
and next to use function base64_encode
and get result to prepare str as data:" . file_mime_type . " base64_encoded string
. Use it in img src attribute. see following code can I help for you.
// A few settings
$img_file = 'raju.jpg';
// Read image path, convert to base64 encoding
$imgData = base64_encode(file_get_contents($img_file));
// Format the image SRC: data:{mime};base64,{data};
$src = 'data: '.mime_content_type($img_file).';base64,'.$imgData;
// Echo out a sample image
echo '<img src="'.$src.'">';
In Spring 3.0 you can make your bean implement BeanDefinitionRegistryPostProcessor
and add new beans via BeanDefinitionRegistry
.
In previous versions of Spring you can do the same thing in BeanFactoryPostProcessor
(though you need to cast BeanFactory
to BeanDefinitionRegistry
, which may fail).
hmm.. just found the answer. it's easier then i thought. it just needs a bunch more stuff:
@echo off
if not exist log.txt GOTO :write
echo Date/Time last login:
type log.txt
del log.txt
:write
echo %date%, %time%. >> log.txt
@pause
exit
So it first reads the log.txt file and deletes it. After that it just get a new file (log.txt) with the date & time!
I hope this helps other people!
(the only prob is that the first time it does not work, but then just enter in random value at log.txt.) (This problem is solved and edited.)
I know that people have been making an Excel "extension" for this purpose.
You more or less make a button in Excel that says "Export to Program X", and then export and send off the data in a format the program can read.
http://msdn.microsoft.com/en-us/library/ms186213.aspx should be a good place to start.
Good luck

I was facing the same issue with Eclipse JUNO & windows XP. After changing a lot of things in eclipse.ini
still it was not working and then i deleted it, i don't know why its starts working after deleting this init file. You may try for yours
Per the docs, you can catch the appropriate exception type (ClientErrorResponseException
for 4xx errors) and call its getResponse()
method to get the response object, then call getBody()
on that:
use Guzzle\Http\Exception\ClientErrorResponseException;
...
try {
$response = $request->send();
} catch (ClientErrorResponseException $exception) {
$responseBody = $exception->getResponse()->getBody(true);
}
Passing true
to the getBody
function indicates that you want to get the response body as a string. Otherwise you will get it as instance of class Guzzle\Http\EntityBody
.
You could also do the following:
// untested
Calendar cal = GregorianCalendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, 23);// I might have the wrong Calendar constant...
cal.set(Calendar.MONTH, 8);// -1 as month is zero-based
cal.set(Calendar.YEAR, 2009);
Timestamp tstamp = new Timestamp(cal.getTimeInMillis());
To have access to stuff provided by math
module, like pi
. You need to import the module first:
import math
print (math.pi)
If you see this warning:
warning: receiver 'MyCoolClass' is a forward class and corresponding @interface may not exist
you need to #import
the file, but you can do that in your implementation file (.m), and use the @class
declaration in your header file.
@class
does not (usually) remove the need to #import
files, it just moves the requirement down closer to where the information is useful.
For Example
If you say @class MyCoolClass
, the compiler knows that it may see something like:
MyCoolClass *myObject;
It doesn't have to worry about anything other than MyCoolClass
is a valid class, and it should reserve room for a pointer to it (really, just a pointer). Thus, in your header, @class
suffices 90% of the time.
However, if you ever need to create or access myObject
's members, you'll need to let the compiler know what those methods are. At this point (presumably in your implementation file), you'll need to #import "MyCoolClass.h"
, to tell the compiler additional information beyond just "this is a class".
If anyone is using SQL and they have meta tags there and still the error is shown, this happens because of your connection from .net to SQL.
In you appsettings.json update your connection string to have: Persist Security Info=True
. So your connection string should look like this:
"DefaultConnection": "Server=[[server]];Initial Catalog=[[db]];Persist Security Info=True;User ID=[[user]];Password=[[pass]];MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;"
I assume you want to run .ps1 file [here $scriptPath along with multiple arguments stored in $argumentList] from another .ps1 file

A lot of problems can be avoided by only creating a branch
to work on & not working on master
:
git checkout -b mybranch
The following works for remote
commits already pushed & a mixture of remote
pushed commits / local
only commits:
# example merging 4 commits
git checkout mybranch
git rebase -i mybranch~4 mybranch
# at the interactive screen
# choose fixup for commit: 2 / 3 / 4
git push -u origin +mybranch
I also have some pull request notes which may be helpful.
Here is a little code to accomplish it:

layoutParams.setMargins(30, 20, 30, 0);
Button okButton=new Button(this);
okButton.setText("some text");
ll.addView(okButton, layoutParams);
You can create two configs for webpack, one that minifies the code and one that doesn't (just remove the optimize.UglifyJSPlugin line) and then run both configurations at the same time $ webpack && webpack --config webpack.config.min.js

data %>% filter(v1 != "b" & v1 != "d" & v1 != "e")
or
data %>% filter(v1 != "b", v1 != "d", v1 != "e")
Since the &
operator is implied by the comma.
If it's conciseness you're after, you might like:
prop.table(table(tips$smoker))
and then scale by 100 and round if you like. Or more like your exact output:
tbl <- table(tips$smoker)
cbind(tbl,prop.table(tbl))
If you wanted to do this for multiple columns, there are lots of different directions you could go depending on what your tastes tell you is clean looking output, but here's one option:
tblFun <- function(x){
tbl <- table(x)
res <- cbind(tbl,round(prop.table(tbl)*100,2))
colnames(res) <- c('Count','Percentage')
res
}
do.call(rbind,lapply(tips[3:6],tblFun))

If you don't like stack the different tables on top of each other, you can ditch the do.call
and leave them in a list.
On some CPUs, there is a dedicated set of registers for the stack. When a call instruction is executed, one register is loaded with the program counter at the same time as a second register is loaded with the contents of the first, a third register is be loaded with the second, and a fourth with the third, etc. When a return instruction is executed, the program counter is latched with the contents of the first stack register and the same time as that register is latched from the second; that second register is loaded from a third, etc. Note that such hardware stacks tend to be rather small (many the smaller PIC series micros, for example, have a two-level stack).
While a hardware stack does have some advantages (push and pop don't add any time to a call/return, for example) having registers which can be loaded with two sources adds cost. If the stack gets very big, it will be cheaper to replace the push-pull registers with an addressable memory. Even if a small dedicated memory is used for this, it's cheaper to have 32 addressable registers and a 5-bit pointer register with increment/decrement logic, than it is to have 32 registers each with two inputs. If an application might need more stack than would easily fit on the CPU, it's possible to use a stack pointer along with logic to store/fetch stack data from main RAM.
All the answers so far given involve reading the file line by line, taking the line in as a String
, and then processing the String
.
There is no question that this is the easiest approach to understand, and if the file is fairly short (say, tens of thousands of lines), it'll also be acceptable in terms of efficiency. But if the file is long, it's a very inefficient way to do it, for two reasons:
String
, and once in processing it.String
for each line, and then throwing it away when you move to the next line. The garbage collector will eventually have to dispose of all these String
objects that you don't want any more. Someone's got to clean up after you.If you care about speed, you are much better off reading a block of data and then processing it byte by byte rather than line by line. Every time you come to the end of a number, you add it to the List
you're building.
It will come out something like this:
private List<Integer> readIntegers(File file) throws IOException {
List<Integer> result = new ArrayList<>();
RandomAccessFile raf = new RandomAccessFile(file, "r");
byte buf[] = new byte[16 * 1024];
final FileChannel ch = raf.getChannel();
int fileLength = (int) ch.size();
final MappedByteBuffer mb = ch.map(FileChannel.MapMode.READ_ONLY, 0,
fileLength);
int acc = 0;
while (mb.hasRemaining()) {
int len = Math.min(mb.remaining(), buf.length);
mb.get(buf, 0, len);
for (int i = 0; i < len; i++)
if ((buf[i] >= 48) && (buf[i] <= 57))
acc = acc * 10 + buf[i] - 48;
else {
result.add(acc);
acc = 0;
}
}
ch.close();
raf.close();
return result;
}
The code above assumes that this is ASCII (though it could be easily tweaked for other encodings), and that anything that isn't a digit (in particular, a space or a newline) represents a boundary between digits. It also assumes that the file ends with a non-digit (in practice, that the last line ends with a newline), though, again, it could be tweaked to deal with the case where it doesn't.
It's much, much faster than any of the String
-based approaches also given as answers to this question. There is a detailed investigation of a very similar issue in this question. You'll see there that there's the possibility of improving it still further if you want to go down the multi-threaded line.

According to nginx documentation
there is no syntax for NOT matching a regular expression. Instead, match the target regular expression and assign an empty block, then use location / to match anything else
So you could define something like
location ~ (dir1|file2\.php) {

}
location / {
rewrite ^/(.*) http://example.com/$1 permanent;
}

You can find the latest features of the .NET Framework 4.5 beta here
It breaks down the changes to the framework in the following categories:
You sound like you are more interested in the Web section as this shows the changes to ASP.NET 4.5. The rest of the changes can be found under the other headings.
You can also see some of the features that were new when the .NET Framework 4.0 was shipped here.

Git 1.7.0 has “sparse checkouts”. See “core.sparseCheckout” in the git config manpage, “Sparse checkout” in the git read-tree manpage, and “Skip-worktree bit” in the git update-index manpage.
The interface is not as convenient as SVN’s (e.g. there is no way to make a sparse checkout at the time of an initial clone), but the base functionality upon which simpler interfaces could be built is now available.
If you need to be able to switch between more than two versions at a time, you can use the following to change the version of PHP manually.
MAMP automatically rewrites the following line in your /Applications/MAMP/conf/apache/httpd.conf file when it restarts based on the settings in preferences. You can comment out this line and add the second one to the end of your file:
# Comment this out just under all the modules loaded
# LoadModule php5_module /Applications/MAMP/bin/php/php5.x.x/modules/libphp5.so
At the bottom of the httpd.conf file, you'll see where additional configurations are loaded from the extra folder. Add this to the bottom of the httpd.conf file
# PHP Version Change
Include /Applications/MAMP/conf/apache/extra/httpd-php.conf
Then create a new file here: /Applications/MAMP/conf/apache/extra/httpd-php.conf
# Uncomment the version of PHP you want to run with MAMP
# LoadModule php5_module /Applications/MAMP/bin/php/php5.2.17/modules/libphp5.so
# LoadModule php5_module /Applications/MAMP/bin/php/php5.3.27/modules/libphp5.so
# LoadModule php5_module /Applications/MAMP/bin/php/php5.4.19/modules/libphp5.so
LoadModule php5_module /Applications/MAMP/bin/php/php5.5.3/modules/libphp5.so
After you have this setup, just uncomment the version of PHP you want to use and restart the servers!
I created this library JS PHP Import which you can download from github, and use whenever and wherever you want.
The library allows importing php functions and class methods into javascript browser environment thus they can be accessed as javascript functions and methods by using their actual names. The code uses javascript promises so you can chain functions returns.
I hope it may useful to you.
Example:
<script>
$scandir(PATH_TO_FOLDER).then(function(result) {
resultObj.html(result.join('<br>'));
});
$system('ls -l').then(function(result) {
resultObj.append(result);
});
$str_replace(' ').then(function(result) {
resultObj.append(result);
});
// Chaining functions
$testfn(34, 56).exec(function(result) { // first call
return $testfn(34, result); // second call with the result of the first call as a parameter
}).exec(function(result) {
resultObj.append('result: ' + result + '<br><br>');
});
</script>
If you are trying to get all parameters passed to Jenkins job you can use the global variable params in your groovy pipeline to fetch it.
http://jenkins_host:8080/pipeline-syntax/globals
params
Exposes all parameters defined in the build as a read-only map with variously typed values. Example:
if (params.BOOLEAN_PARAM_NAME) {doSomething()} or to supply a nontrivial default value:
if (params.get('BOOLEAN_PARAM_NAME', true)) {doSomething()} Note for multibranch (Jenkinsfile) usage: the properties step allows you to define job properties, but these take effect when the step is run, whereas build parameter definitions are generally consulted before the build begins. As a convenience, any parameters currently defined in the job which have default values will also be listed in this map. That allows you to write, for example:
properties([parameters([string(name: 'BRANCH', defaultValue: 'master')])]) git url: '…', branch: params.BRANCH and be assured that the master branch will be checked out even in the initial build of a branch project, or if the previous build did not specify parameters or used a different parameter name.
Use something like below.
def dumpParameter()
{
params.each {
println it.key + " = " + it.value
}
}
the pom.xml for the project I have doesn't have this "http://repo1.maven.org/myurlhere" anywhere in it
All projects have http://repo1.maven.org/ declared as <repository>
(and <pluginRepository>
) by default. This repository, which is called the central repository, is inherited like others default settings from the "Super POM" (all projects inherit from the Super POM). So a POM is actually a combination of the Super POM, any parent POMs and the current POM. This combination is called the "effective POM" and can be printed using the effective-pom
goal of the Maven Help plugin (useful for debugging).
And indeed, if you run:
mvn help:effective-pom
You'll see at least the following:

</pluginRepository>
</pluginRepositories>
it has the absolute url where the maven repo is for the project but maven is still trying to download from the general maven repo
Maven will try to find dependencies in all repositories declared, including in the central one which is there by default as we saw. But, according to the trace you are showing, you only have one repository defined (the central repository) or maven would print something like this:
Reason: Unable to download the artifact from any repository
url.project:project:pom:x.x
from the specified remote repositories:
central (http://repo1.maven.org/),
another-repository (http://another/repository)
So, basically, maven is unable to find the url.project:project:pom:x.x
because it is not available in central.
But without knowing which project you've checked out (it has maybe specific instructions) or which dependency is missing (it can maybe be found in another repository), it's impossible to help you further.
The plug offered by Vinny is really close, but I found and fixed a couple of small issues.
For table cells with lots of content (like a nested table with lots of rows), calling slideRow('up'), regardless of the slideSpeed value provided, it'd collapse the view of the row as soon as the padding animation was done.

check the command : NA!=NA
: you'll get the result NA
, hence the error message.
You have to use the function is.na
for your if
statement to work (in general, it is always better to use this function to check for NA
values) :
comments = c("no","yes",NA)
for (l in 1:length(comments)) {
if (!is.na(comments[l])) print(comments[l])
}
[1] "no"

pandas DataFrame/Series

:The top answers are optimized methods for single point calculation, but when you want to apply these methods to a pandas series or numpy array, it requires apply
, which is basically for loop in the background and will iterate over every row and apply the method. This is quite inefficient.
To speed up our code, we can make use of vectorization and numpy broadcasting:

The best way I have found is to use the initComplete method as it fires after the data has been retrieved and renders the table. NOTE this only fires once though.
$("#tableOfData").DataTable({
"pageLength": 50,
"ajax":{
url: someurl,
dataType : "json",
type: "post",
"data": {data to be sent}
},
"initComplete":function( settings, json){
console.log(json);
// call your function here
}
});
Coming from someone who has tried a number of "C# IDEs" on the Mac, your best bet is to install a virtual desktop with Windows and Visual Studio. It really is the best development IDE out there for .NET, nothing even comes close.
On a related note: I hate XCode.
Update: Use Xamarin Studio. It's solid.
You could look for the presence of a map key or see if it's in a set.
Depending on what you're actually doing, though, you might be trying to solve the problem wrong :)
As of 2013, if you're using facebook.com/sharer.php (PHP) you can simply make any button/link like:
<a class="btn" target="_blank" href="http://www.facebook.com/sharer.php?s=100&p[title]=<?php echo urlencode(YOUR_TITLE);?>&p[summary]=<?php echo urlencode(YOUR_PAGE_DESCRIPTION) ?>&p[url]=<?php echo urlencode(YOUR_PAGE_URL); ?>&p[images][0]=<?php echo urlencode(YOUR_LINK_THUMBNAIL); ?>">share on facebook</a>
Link query parameters:
p[title] = Define a page title
p[summary] = An URL description, most likely describing the contents of the page
p[url] = The absolute URL for the page you're sharing
p[images][0] = The URL of the thumbnail image to be used as post thumbnail on facebook
It's plain simple: you do not need any js or other settings. Is just an HTML raw link. Style the A tag in any way you want to.
Try IDLE, and use Alt + X to find indentation.
You have to escape the & character. Turn your
&
into
&
and you should be good.
You have to use ':' colon instead of ';' semicolon.
As it stands now you try to execute the jar file which has not the execute bit set, hence the Permission denied.
And the variable must be CLASSPATH not classpath.
If I understand correctly, you need a regex statement that checks for at least 6 characters (letters & numbers)?
/[0-9a-zA-Z]{6,}/
Format formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String s = formatter.format(date);
Edit: This does not work cross domain unless the appropriate CORS header is set.
There are two different things here: the style of the iframe block and the style of the page embedded in the iframe. You can set the style of the iframe block the usual way:
<iframe name="iframe1" id="iframe1" src="empty.htm"
frameborder="0" border="0" cellspacing="0"
style="border-style: none;width: 100%; height: 120px;"></iframe>
The style of the page embedded in the iframe must be either set by including it in the child page:
<link type="text/css" rel="Stylesheet" href="Style/simple.css" />
Or it can be loaded from the parent page with Javascript:
var cssLink = document.createElement("link");
cssLink.href = "style.css";
cssLink.rel = "stylesheet";
cssLink.type = "text/css";
frames['iframe1'].document.head.appendChild(cssLink);
Not very efficient, but if you must use a list, you can deference the iterator
*myList.begin()+N
Actually, there is no need to restore the database in native SQL Server terms, since you "want to fiddle with some data" and "browse through the data of that .bak file"
You can use ApexSQL Restore – a SQL Server tool that attaches both native and natively compressed SQL database backups and transaction log backups as live databases, accessible via SQL Server Management Studio, Visual Studio or any other third-party tool. It allows attaching single or multiple full, differential and transaction log backups
Moreover, I think that you can do the job while the tool is in fully functional trial mode (14 days)
Disclaimer: I work as a Product Support Engineer at ApexSQL
Check your short_open_tag setting (use <?php phpinfo() ?>

There are 3 basic commands to compare files in unix:
cmp
: This command is used to compare two files byte by byte and as any mismatch occurs,it echoes it on the screen.if no mismatch occurs i gives no response.
syntax:$cmp file1 file2.
comm
: This command is used to find out the records available in one but not in another
diff
I encountered the same problem in child components where initially it would have to have the current value of the Subject, then subscribe to the Subject to listen to changes. I just maintain the current value in the Service so it is available for components to access, e.g. :
import {Storage} from './storage';
import {Injectable} from 'angular2/core';
import {Subject} from 'rxjs/Subject';
@Injectable()
export class SessionStorage extends Storage {
isLoggedIn: boolean;
private _isLoggedInSource = new Subject<boolean>();
isLoggedIn = this._isLoggedInSource.asObservable();
constructor() {
super('session');
this.currIsLoggedIn = false;
}
setIsLoggedIn(value: boolean) {
this.setItem('_isLoggedIn', value, () => {
this._isLoggedInSource.next(value);
});
this.isLoggedIn = value;
}
}
A component that needs the current value could just then access it from the service, i.e,:
sessionStorage.isLoggedIn
Not sure if this is the right practice :)
Replace URLs in text with HTML links, ignore the URLs within a href/pre tag. https://github.com/JimLiu/auto-link
If you want to remove only the last newline, pipe through:
sed -z '$ s/\n$//'
sed
won't add a \0
to then end of the stream if the delimiter is set to NUL
via -z
, whereas to create a POSIX text file (defined to end in a \n
), it will always output a final \n
without -z
.
Eg:
$ { echo foo; echo bar; } | sed -z '$ s/\n$//'; echo tender
foo
bartender
And to prove no NUL
added:
$ { echo foo; echo bar; } | sed -z '$ s/\n$//' | xxd
00000000: 666f 6f0a 6261 72 foo.bar
To remove multiple trailing newlines, pipe through:
sed -Ez '$ s/\n+$//'
The issue is with the Version of JSCH jar you are using.
Update it to latest jar.
I was also getting the same error and this solution worked.
You can download latest jar from
To compile you could just initiate a shell call to the csc compiler. You may have a headache trying to keep your paths and switches straight but it certainly can be done.
EDIT: Or better yet, use the CodeDOM as Noldorin suggested...
Just one line of coding is enough.. just try this out. and you can adjust even thicknes of icon-bar with this by adding pixels.
HTML
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#defaultNavbar1" aria-expanded="false"><span class="sr-only">Toggle navigation</span>

BOOM...
Given that all the dataframes have the same columns, you can simply concat

df = pd.concat(list_of_dataframes)
For fun, I wrote a little jQuery add-on method that will check for any one of multiple class names:
$.fn.hasAnyClass = function() {
for (var i = 0; i < arguments.length; i++) {
if (this.hasClass(arguments[i])) {
return true;
}
}
return false;
}
Then, in your example, you could use this:
if ($('html').hasAnyClass('m320', 'm768')) {
// do stuff
}
You can pass as many class names as you want.
Here's an enhanced version that also lets you pass multiple class names separated by a space:
$.fn.hasAnyClass = function() {
for (var i = 0; i < arguments.length; i++) {
var classes = arguments[i].split(" ");
for (var j = 0; j < classes.length; j++) {
if (this.hasClass(classes[j])) {
return true;
}
}
}
return false;
}
if ($('html').hasAnyClass('m320 m768')) {
// do stuff
}

You want to use the array_key_exists function.
It seems you need DataFrame.var
:
Normalized by N-1 by default. This can be changed using the ddof argument
var1 = credit_card.var()
Sample:
#random dataframe
np.random.seed(100)
credit_card = pd.DataFrame(np.random.randint(10, size=(5,5)), columns=list('ABCDE'))
print (credit_card)
A B C D E
0 8 8 3 7 7
1 0 4 2 5 2
2 2 2 1 0 8
3 4 0 9 6 2
4 4 1 5 3 4
var1 = credit_card.var()
print (var1)
A 8.8
B 10.0
C 10.0
D 7.7
E 7.8
dtype: float64
var2 = credit_card.var(axis=1)
print (var2)
0 4.3
1 3.8
2 9.8
3 12.2

dtype: float64
If need numpy solutions with numpy.var
:
print (np.var(credit_card.values, axis=0))
[ 7.04 8. 8. 6.16 6.24]
print (np.var(credit_card.values, axis=1))
[ 3.44 3.04 7.84 9.76 1.84]
Differences are because by default ddof=1
in pandas
, but you can change it to 0
:
var1 = credit_card.var(ddof=0)
print (var1)
A 7.04
B 8.00

I needed to copy all .md files from one directory into another, so here is what I did.
for i in **/*.md;do mkdir -p ../docs/"$i" && rm -r ../docs/"$i" && cp "$i" "../docs/$i" && echo "$i -> ../docs/$i"; done
Which is pretty hard to read, so lets break it down.
first cd into the directory with your files,
for i in **/*.md;
for each file in your pattern
mkdir -p ../docs/"$i"
make that directory in a docs folder outside of folder containing your files. Which creates an extra folder with the same name as that file.
rm -r ../docs/"$i"
remove the extra folder that is created as a result of mkdir -p
cp "$i" "../docs/$i"
Copy the actual file
echo "$i -> ../docs/$i"
Echo what you did
; done
Live happily ever after

Its good one
Still its better preferred to test on real device..
Hope this info helps you..
$("#select-id").chosen().val()
this is one:
ls -l . | egrep -c '^-'

|
: pipe output onto...

I'd like to add to @MBK's answer. Although I found @MBK's answer to be very helpful in solving a similar problem, it'd be better if @MBK included a screenshot of how to filter a particular column.
Use str.join
:
>>> tup = ('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e')
>>> ''.join(tup)
'abcdgxre'
>>>
>>> help(str.join)
Help on method_descriptor:
join(...)
S.join(iterable) -> str
Return a string which is the concatenation of the strings in the
iterable. The separator between elements is S.
>>>
In your example, You don't need to. As a standard programming practice, all variables being referred to inside some code block, say for example try{} catch(){}
, and being referred to outside the block as well, you need to declare the variables outside the try block first e.g.
This is helpful when your equals method call throws some exception e.g. NullPointerException
;
boolean isMatch = false;
try{
isMatch = email1.equals (email2);
}catch(NullPointerException npe){
.....
}
System.out.print("Match=="+isMatch);
if(isMatch){
......
}
Also a solution, which gives only the first appearance, can be achieved by using numpy
:
>>> import numpy as np
>>> a_np = np.array(a)
>>> np.argmax(a_np)

UPDATE
only changes the values you specify:
UPDATE table SET cell='new_value' WHERE whatever='somevalue'
"Update-Package –reinstall Microsoft.AspNet.WebPages"
Reinstall Microsoft.AspNet.WebPages nuget packages using this command in the package manager console. 100% work!!
Using the accepted answer you have to access each record by using Customers[i].customer
, and you need an extra CustomerJson
class, which is a little annoying. If you don't want to do that, you can use the following:
public class CustomerList
{
[JsonConverter(typeof(MyListConverter))]
public List<Customer> customer { get; set; }
}
Note that I'm using a List<>
, not an Array. Now create the following class:
class MyListConverter : JsonConverter
{
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
var token = JToken.Load(reader);
var list = Activator.CreateInstance(objectType) as System.Collections.IList;
var itemType = objectType.GenericTypeArguments[0];
foreach (var child in token.Values())
{
var childToken = child.Children().First();
var newObject = Activator.CreateInstance(itemType);
serializer.Populate(childToken.CreateReader(), newObject);
list.Add(newObject);
}
return list;
}
public override bool CanConvert(Type objectType)
{
return objectType.IsGenericType && (objectType.GetGenericTypeDefinition() == typeof(List<>));
}
public override bool CanWrite => false;
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) => throw new NotImplementedException();
}
Eclipse has built in JUnit functionality. Open your Run Configuration manager to create a test to run. You can also create JUnit Test Cases/Suites from New->Other.
onRestoreInstanceState()
is called only when recreating activity after it was killed by the OS. Such situation happen when:
In contrast: if you are in your activity and you hit Back
button on the device, your activity is finish()ed (i.e. think of it as exiting desktop application) and next time you start your app it is started "fresh", i.e. without saved state because you intentionally exited it when you hit Back
.
Other source of confusion is that when an app loses focus to another app onSaveInstanceState()
is called but when you navigate back to your app onRestoreInstanceState()
may not be called. This is the case described in the original question, i.e. if your activity was NOT killed during the period when other activity was in front onRestoreInstanceState()
will NOT be called because your activity is pretty much "alive".
All in all, as stated in the documentation for onRestoreInstanceState()
:
Most implementations will simply use onCreate(Bundle) to restore their state, but it is sometimes convenient to do it here after all of the initialization has been done or to allow subclasses to decide whether to use your default implementation. The default implementation of this method performs a restore of any view state that had previously been frozen by onSaveInstanceState(Bundle).
As I read it: There is no reason to override onRestoreInstanceState()
unless you are subclassing Activity
and it is expected that someone will subclass your subclass.
Why not:
public class MyClass
{
private Dictionary<string, int> _myCollection = new Dictionary<string, int>() { { "A", 1 }, { "B", 2 }, { "C", 3 } };
public IEnumerable<KeyValuePair<string,int>> MyCollection
{
get { return _myCollection.AsEnumerable<KeyValuePair<string, int>>(); }
}
}
disabling PHP-FPM fixed my issue.
I did the same that user9876226 answered.
The only differemce is, that I don't usually use the onClickListener. Instead I write following in the xml-file: android:onClick="open"
open
is the function, that is bound to the button.
Then just create the function open() in your activity class. When you click on the button, this function will be called :)
Also, I think this way is more confortable than using the listener.
From the point of view of porting a C program, a good way to understand this is to take an example:
#include <sys/stat.h>
#include <stdlib.h>
int main(void)
{
struct stat stbuf;
stat("c:foo.txt", &stbuf);
system("command");
printf("Hello, World\n");
return 0;
}
If we change stat
to _stat
, we can compile this program with Microsoft Visual C. We can also compile this program with MinGW, and with Cygwin.
Under Microsoft Visual C, the program will be linked to a MSVC redistributable run-time library: mxvcrtnn.dll
, where nn
is some version suffix. To ship this program we will have to include that DLL. That DLL provides _stat
, system
and printf
. (We also have the option of statically linking the run-time.)
Under MinGW, the program will be linked to msvcrt.dll
, which is an internal, undocumented, unversioned library that is part of Windows, and off-limits to application use. That library is essentially a fork of the redistributable run-time library from MS Visual C for use by Windows itself.
Under both of these, the program will have similar behaviors:
stat
function will return very limited information—no useful permissions or inode number, for instance.c:file.txt
is resolved according to the current working directory associated with drive c:
. system
uses cmd.exe /c
for running the external command.We can also compile the program under Cygwin. Similarly to the redistributable run-time used by MS Visual C, the Cygwin program will be linked to Cygwin's run-time libraries: cygwin1.dll
(Cygwin proper) and cyggcc_s-1.dll
(GCC run-time support). Since Cygwin is now under the LGPL, we can package with our program, even if it isn't GPL-compatible free software, and ship the program.
Under Cygwin, the library functions will behave differently:
stat
function has rich functionality, returning meaningful values in most of the fields.c:file.txt
is not understood at all as containing a drive letter reference, since c:
isn't followed by a slash. The colon is considered part of the name and somehow mangled into it. There is no concept of a relative path against a volume or drive in Cygwin, no "currently logged drive" concept, and no per-drive current working directory.system
function tries to use the /bin/sh -c
interpreter. Cygwin will resolve the /
path according to the location of your executable, and expect a sh.exe
program to be co-located with your executable.Both Cygwin and MinGW allow you to use Win32 functions. If you want to call MessageBox
or CreateProcess
, you can do that. You can also easily build a program which doesn't require a console window, using gcc -mwindows
, under MinGW and Cygwin.
Cygwin is not strictly POSIX. In addition to providing access to the Windows API, it also provides its own implementations of some Microsoft C functions (stuff found in msvcrt.dll
or the re-distributable msvcrtnn.dll
run-times). An example of this are the spawn*
family of functions like spawnvp
. These are a good idea to use instead of fork
and exec
on Cygwin since they map better to the Windows process creation model which has no concept of fork
.
Thus:
Cygwin programs are no less "native" than MS Visual C programs on grounds of requiring the accompaniment of libraries. Programming language implementations on Windows are expected to provide their own run-time, even C language implementations. There is no "libc" on Windows for public use.
The fact that MinGW requires no third-party DLL is actually a disadvantage; it is depending on an undocumented, Windows-internal fork of the Visual C run-time. MinGW does this because the GPL system library exception applies to msvcrt.dll
, which means that GPL-ed programs can be compiled and redistributed with MinGW.
Due to its much broader and deeper support for POSIX compared to msvcrt.dll
, Cygwin is by far the superior environment for porting POSIX programs. Since it is now under the LGPL, it allows applications with all sorts of licenses, open or closed source, to be redistributed. Cygwin even contains VT100 emulation and termios
, which work with the Microsoft console! A POSIX application that sets up raw mode with tcsetattr
and uses VT100 codes to control the cursor will work right in the cmd.exe
window. As far as the end-user is concerned, it's a native console app making Win32 calls to control the console.
However:
/bin/sh
and other issues. These differences are what render Cygwin programs "non-native". If a program takes a path as an argument, or input from a dialog box, Windows users expect that path to work the same way as it does in other Windows programs. If it doesn't work that way, that's a problem.Plug: Shortly after the LGPL announcement, I started the Cygnal (Cygwin Native Application Library) project to provide a fork of the Cygwin DLL which aims to fix these issues. Programs can be developed under Cygwin, and then deployed with the Cygnal version of cygwin1.dll
without recompiling. As this library improves, it will gradually eliminate the need for MinGW.
When Cygnal solves the path handling problem, it will be possible to develop a single executable which works with Windows paths when shipped as a Windows application with Cygnal, and seamlessly works with Cygwin paths when installed in your /usr/bin
under Cygwin. Under Cygwin, the executable will transparently work with a path like /cygdrive/c/Users/bob
. In the native deployment where it is linking against the Cygnal version of cygwin1.dll
, that path will make no sense, whereas it will understand c:foo.txt
.
We can use the get_locale
function:
if (get_locale() == 'en_GB') {
// drink tea
}
In my case, I accidentally typed an unnecessary dot at the end of the config file which caused this strange problem. Please make sure your config file does not contain any errors!
With version 2.3.4, you need the to add the owl.autoplay.js plugin. Then do the following
var owl = $('.owl-carousel');
owl.owlCarousel({
items:1, //how many items you want to display
loop:true,
margin:10,
autoplay:true,
autoplayTimeout:10000,
autoplayHoverPause:true
});
You need to include a declaration of the printf()
function.
#include <stdio.h>
ORDER BY
is always last...
However, you need to pick the fields you ACTUALLY WANT then select only those and group by them. SELECT *
and GROUP BY Email
will give you RANDOM VALUES for all the fields but Email
. Most RDBMS will not even allow you to do this because of the issues it creates, but MySQL is the exception.
SELECT Email, COUNT(*)
FROM user_log
GROUP BY Email
HAVING COUNT(*) > 1
ORDER BY UpdateDate DESC
Use LINQ Aggregate
method to convert array of integers to a comma separated string
var intArray = new []{1,2,3,4};
string concatedString = intArray.Aggregate((a, b) =>Convert.ToString(a) + "," +Convert.ToString( b));
Response.Write(concatedString);
output will be
1,2,3,4
This is one of the solution you can use if you have not .net 4 installed.
a % b
in c++ default:

in python:
-7 % 3 => 2
7 % -3 => -2
in c++ to python:

A very simple way to do so with IPython that worked for me in Visual Studio Code is to add the following:

}
to the keybindings.json that you can access by typing F1 and 'open keyboard shortcuts'.
Try shFlags -- Advanced command-line flag library for Unix shell scripts.
http://code.google.com/p/shflags/
It is very good and very flexible.
FLAG TYPES: This is a list of the DEFINE_*'s that you can do. All flags take a name, default value, help-string, and optional 'short' name (one-letter name). Some flags have other arguments, which are described with the flag.
DEFINE_string: takes any input, and intreprets it as a string.
DEFINE_boolean: typically does not take any argument: say --myflag to set FLAGS_myflag to true, or --nomyflag to set FLAGS_myflag to false. Alternately, you can say --myflag=true or --myflag=t or --myflag=0 or --myflag=false or --myflag=f or --myflag=1 Passing an option has the same affect as passing the option once.
DEFINE_float: takes an input and intreprets it as a floating point number. As shell does not support floats per-se, the input is merely validated as being a valid floating point value.
DEFINE_integer: takes an input and intreprets it as an integer.
SPECIAL FLAGS: There are a few flags that have special meaning: --help (or -?) prints a list of all the flags in a human-readable fashion --flagfile=foo read flags from foo. (not implemented yet) -- as in getopt(), terminates flag-processing
EXAMPLE USAGE:
-- begin hello.sh --
! /bin/sh
. ./shflags
DEFINE_string name 'world' "somebody's name" n
FLAGS "$@" || exit $?
eval set -- "${FLAGS_ARGV}"
echo "Hello, ${FLAGS_name}."
-- end hello.sh --
$ ./hello.sh -n Kate
Hello, Kate.
Note: I took this text from shflags documentation

NULL
is not a built-in constant in the C or C++ languages. In fact, in C++ it's more or less obsolete, just use a plain literal 0
instead, the compiler will do the right thing depending on the context.
In newer C++ (C++11 and higher), use nullptr
(as pointed out in a comment, thanks).
Otherwise, add
#include <stddef.h>
to get the NULL
definition.
pip
is just a PyPI package like any other; you could use it to upgrade itself the same way you would upgrade any package:
pip install --upgrade pip
On Windows the recommended command is:
python -m pip install --upgrade pip
The new git-switch
command (starting in GIT 2.23) also has a flag --discard-changes
which should help you. git pull
might be necessary afterwards.
Warning: it's still considered to be experimental.
Shouldn't you be providing the credentials for your site, instead of passing the DefaultCredentials?
Something like request.Credentials = new NetworkCredential("UserName", "PassWord");
Also, remove request.UseDefaultCredentials = true; request.PreAuthenticate = true;
This question is very general and there are a couple of assumptions I'll make to simplify it a bit. We'll assume that you want to update your master
branch.
If you haven't made any changes locally, you can use git pull
to bring down any new commits and add them to your master
.
git pull origin master
If you have made changes, and you want to avoid adding a new merge commit, use git pull --rebase
.
git pull --rebase origin master
git pull --rebase
will work even if you haven't made changes and is probably your best call.
I am sorry, but none of these answers provide an optimal solution. If you use a library such as OpenCSV you will have to write a lot of code to handle special cases to extract information from specific columns.
For example, if you have rows with less columns than what you're after, you'll have to write a lot of code to handle it. Using the OpenCSV example:
CSVReader reader = new CSVReader(new FileReader(strFile));
String [] nextLine;
while ((nextLine = reader.readNext()) != null) {
//let's say you are interested in getting columns 20, 30, and 40
String[] outputRow = new String[3];
if(parsedRow.length < 40){
outputRow[2] = null;
} else {
outputRow[2] = parsedRow[40]
}
if(parsedRow.length < 30){
outputRow[1] = null;
} else {
outputRow[1] = parsedRow[30]
}
if(parsedRow.length < 20){
outputRow[0] = null;
} else {
outputRow[0] = parsedRow[20]
}
}
This is a lot of code for a simple requirement. It gets worse if you are trying to get values of columns by name. You should use a more modern parser such as the one provided by uniVocity-parsers.
To reliably and easily get the columns you want, simply write:
CsvParserSettings settings = new CsvParserSettings();
parserSettings.selectIndexes(20, 30, 40);
CsvParser parser = new CsvParser(settings);
List<String[]> allRows = parser.parseAll(new FileReader(yourFile));

Go and install latest JDK
Make sure you have installed 64 bit Eclipse
This code snippet uses the DataContractJsonSerializer from System.Runtime.Serialization.Json in .NET 3.5.

using (var stream = new MemoryStream())
{
using (var writer = JsonReaderWriterFactory.CreateJsonWriter(stream, encoding))
{
serializer.WriteObject(writer, value);
}
return encoding.GetString(stream.ToArray());
}
}
You are trying to call DeckOfCards::shuffle
with a deckOfCards
parameter:
deckOfCards cardDeck; // create DeckOfCards object
cardDeck.shuffle(cardDeck); // shuffle the cards in the deck
But the method takes a vector<Card>&
:
void deckOfCards::shuffle(vector<Card>& deck)
The compiler error messages are quite clear on this. I'll paraphrase the compiler as it talks to you.
Error:
[Error] no matching function for call to 'deckOfCards::shuffle(deckOfCards&)'
Paraphrased:
Hey, pal. You're trying to call a function called
shuffle
which apparently takes a single parameter of type reference-to-deckOfCards
, but there is no such function.
Error:
[Note] candidate is:
In file included from main.cpp
[Note] void deckOfCards::shuffle(std::vector&)
Paraphrased:
I mean, maybe you meant this other function called
shuffle
, but that one takes a reference-tovector<something>
.
Error:
[Note] no known conversion for argument 1 from 'deckOfCards' to 'std::vector&'
Which I'd be happy to call if I knew how to convert from a
deckOfCards
to avector
; but I don't. So I won't.
The HTTP status code you return should depend on the type of error that has occurred. If an ID doesn't exist in the database, return a 404; if a user doesn't have enough privileges to make that Ajax call, return a 403; if the database times out before being able to find the record, return a 500 (server error).
jQuery automatically detects such error codes, and runs the callback function that you define in your Ajax call. Documentation: http://api.jquery.com/jQuery.ajax/
Short example of a $.ajax
error callback:
$.ajax({
type: 'POST',
url: '/some/resource',
success: function(data, textStatus) {
// Handle success
},
error: function(xhr, textStatus, errorThrown) {
// Handle error
}
});
We tried a few applications, both trials of commercial products and freely available ones. Ultimately, it was the trial edition of the Team Test Load Agent software that we tried. It definitely works great and is fairly simple to use. In the long run, it bolstered our argument to move to Team Foundation Server and equip all parts of the department with the appropriate tooling.
The obvious downside, however, is the price.

You could use the object data type:
>>> import numpy
>>> s = numpy.array(['a', 'b', 'dude'], dtype='object')
>>> s[0] += 'bcdef'
>>> s
array([abcdef, b, dude], dtype=object)
If you want to create a .war file you can deploy to a Tomcat instance using the Manager app, create a folder, put all your files in that folder (including an index.html file) move your terminal window into that folder, and execute the following command:
zip -r <AppName>.war *
I've tested it with Tomcat 8 on the Mac, but it should work anywhere
If, for example, x = 5 and is stored as string, you can also just:
x = x + 0
and the new x would be stored as a numeric value.
You can pass $ in function()
jQuery(document).ready(function($){
// jQuery code is in here
});
or you can replace $(document);
with this jQuery(document);
or you can use jQuery.noConflict()
var jq=jQuery.noConflict();
jq(document).ready(function(){
jq('selector').show();
});
The only problem could be if one day
map[key] = value
will transform to -
map[key]++;
and that will cause a KeyNotFoundException.
Take a look in the code below.
First, we create custom layouts. In this case, four types.
even.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#ff500000"
android:layout_height="match_parent">
<TextView
android:id="@+id/text"
android:textColor="@android:color/white"
android:layout_width="match_parent"
android:layout_gravity="center"
android:textSize="24sp"
android:layout_height="wrap_content" />
</LinearLayout>
odd.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#ff001f50"
android:gravity="right"
android:layout_height="match_parent">
<TextView
android:id="@+id/text"
android:textColor="@android:color/white"
android:layout_width="wrap_content"
android:layout_gravity="center"
android:textSize="28sp"
android:layout_height="wrap_content" />
</LinearLayout>
white.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#ffffffff"
android:gravity="right"
android:layout_height="match_parent">
<TextView
android:id="@+id/text"
android:textColor="@android:color/black"
android:layout_width="wrap_content"
android:layout_gravity="center"
android:textSize="28sp"
android:layout_height="wrap_content" />
</LinearLayout>
black.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#ff000000"
android:layout_height="match_parent">
<TextView
android:id="@+id/text"
android:textColor="@android:color/white"
android:layout_width="wrap_content"
android:layout_gravity="center"
android:textSize="33sp"
android:layout_height="wrap_content" />
</LinearLayout>
Then, we create the listview item. In our case, with a string and a type.
public class ListViewItem {
private String text;
private int type;
public ListViewItem(String text, int type) {
this.text = text;
this.type = type;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public int getType() {
return type;
}
public void setType(int type) {
this.type = type;
}
}
After that, we create a view holder. It's strongly recommended because Android OS keeps the layout reference to reuse your item when it disappears and appears back on the screen. If you don't use this approach, every single time that your item appears on the screen Android OS will create a new one and causing your app to leak memory.
public class ViewHolder {
TextView text;
public ViewHolder(TextView text) {
this.text = text;
}
public TextView getText() {
return text;
}
public void setText(TextView text) {
this.text = text;
}
}
Finally, we create our custom adapter overriding getViewTypeCount() and getItemViewType(int position).
public class CustomAdapter extends ArrayAdapter {
public static final int TYPE_ODD = 0;
public static final int TYPE_EVEN = 1;
public static final int TYPE_WHITE = 2;
public static final int TYPE_BLACK = 3;
private ListViewItem[] objects;
@Override
public int getViewTypeCount() {
return 4;
}
@Override
public int getItemViewType(int position) {
return objects[position].getType();
}
public CustomAdapter(Context context, int resource, ListViewItem[] objects) {
super(context, resource, objects);
this.objects = objects;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
ListViewItem listViewItem = objects[position];
int listViewItemType = getItemViewType(position);
if (convertView == null) {
if (listViewItemType == TYPE_EVEN) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.type_even, null);
} else if (listViewItemType == TYPE_ODD) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.type_odd, null);
} else if (listViewItemType == TYPE_WHITE) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.type_white, null);
} else {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.type_black, null);
}
TextView textView = (TextView) convertView.findViewById(R.id.text);
viewHolder = new ViewHolder(textView);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.getText().setText(listViewItem.getText());
return convertView;
}
}
And our activity is something like this:
private ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); // here, you can create a single layout with a listview
listView = (ListView) findViewById(R.id.listview);
final ListViewItem[] items = new ListViewItem[40];
for (int i = 0; i < items.length; i++) {
if (i == 4) {
items[i] = new ListViewItem("White " + i, CustomAdapter.TYPE_WHITE);
} else if (i == 9) {
items[i] = new ListViewItem("Black " + i, CustomAdapter.TYPE_BLACK);
} else if (i % 2 == 0) {
items[i] = new ListViewItem("EVEN " + i, CustomAdapter.TYPE_EVEN);
} else {
items[i] = new ListViewItem("ODD " + i, CustomAdapter.TYPE_ODD);
}
}
CustomAdapter customAdapter = new CustomAdapter(this, R.id.text, items);
listView.setAdapter(customAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView adapterView, View view, int i, long l) {
Toast.makeText(getBaseContext(), items[i].getText(), Toast.LENGTH_SHORT).show();
}
});
}
}
now create a listview inside mainactivity.xml like this
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.shivnandan.gygy.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main" />
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/listView"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_marginTop="100dp" />

You're in luck, I use the exact thing in my CMS
When you want to store the order, just call the JavaScript method saveOrder()
. It will make an AJAX POST
request to saveorder.php, but of course you could always post it as a regular form.
<script type="text/javascript">
function saveOrder() {
var articleorder="";
$("#sortable li").each(function(i) {
if (articleorder=='')
articleorder = $(this).attr('data-article-id');
else
articleorder += "," + $(this).attr('data-article-id');
});
//articleorder now contains a comma separated list of the ID's of the articles in the correct order.
$.post('/saveorder.php', { order: articleorder })
.success(function(data) {
alert('saved');
})
.error(function(data) {
alert('Error: ' + data);
});
}
</script>
<ul id="sortable">
<?php
//my way to get all the articles, but you should of course use your own method.
$articles = Page::Articles();
foreach($articles as $article) {
?>
<li data-article-id='<?=$article->Id()?>'><?=$article->Title()?></li>
<?
}
?>
</ul>
<input type='button' value='Save order' onclick='saveOrder();'/>
In saveorder.php; Keep in mind I removed all verification and checking.
<?php
$orderlist = explode(',', $_POST['order']);
foreach ($orderlist as $k=>$order) {
echo 'Id for position ' . $k . ' = ' . $order . '<br>';
}
?>
The @overload
decorator was added with type hints (PEP 484).
While this doesn't change the behaviour of Python, it does make it easier to understand what is going on, and for mypy to detect errors.
See: Type hints and PEP 484
The following is easy to remember
ls -ltrapR
list directory contents
-l use a long listing format
-t sort by modification time, newest first
-r, --reverse reverse order while sorting
-a, --all do not ignore entries starting with .
-p, --indicator-style=slash append / indicator to directories
-R, --recursive list subdirectories recursively
Yes, the first means "match all strings that start with a letter", the second means "match all strings that contain a non-letter". The caret ("^") is used in two different ways, one to signal the start of the text, one to negate a character match inside square brackets.
Yes. IE7+ supports attribute selectors:
input[type=radio]
input[type^=ra]
input[type*=d]
input[type$=io]
Element input with attribute type which contains a value that is equal to, begins with, contains or ends with a certain value.
Other safe (IE7+) selectors are:
p > span { font-weight: bold; }
span ~ span { color: blue; }
Which for <p><span/><span/></p>
would effectively give you:
<p>
<span style="font-weight: bold;">
<span style="font-weight: bold; color: blue;">
</p>
Further reading: Browser CSS compatibility on quirksmode.com
I'm surprised that everyone else thinks it can't be done. CSS attribute selectors have been here for some time already. I guess it's time we clean up our .css files.
A more readable version of the ternary might look like:
var x = this.dealer;
alert(t < 1 || t > 11
? 'none'
: t < 5
? 'less than five'
: t <= 8
? 'between 5 and 8'
: 'Between 9 and 11');
Just add the percentage value into a variable and use #{$variable}
for example
$twentyFivePercent:25%;
.selector {
height: calc(#{$twentyFivePercent} - 5px);
}
The only time you should worry your users about something that happened in the code is if there is something they can or need to do to avoid the issue. If they can change data on a form, push a button or change a application setting in order to avoid the issue then let them know. But warnings or errors that the user has no ability to avoid just makes them lose confidence in your product.
Exceptions and Logs are for you, the developer, not your end user. Understanding the right thing to do when you catch each exception is far better than just applying some golden rule or rely on an application-wide safety net.
Mindless coding is the ONLY kind of wrong coding. The fact that you feel there is something better that can be done in those situations shows that you are invested in good coding, but avoid trying to stamp some generic rule in these situations and understand the reason for something to throw in the first place and what you can do to recover from it.
Oracle syntax from the 11g Documentation:
CASE { simple_case_expression | searched_case_expression }
[ else_clause ]
END
simple_case_expression
expr { WHEN comparison_expr THEN return_expr }...
searched_case_expression
{ WHEN condition THEN return_expr }...
else_clause
ELSE else_expr
You need to escape it: on many databases this is done by preceding it with backslash, \%
.
So abc
becomes abc\%
.
Your programming language will have a database-specific function to do this for you. For example, PHP has mysql_escape_string() for the MySQL database.
Try -Wno-traditional
.
But better, add declarations for your static functions:
static void foo (void);
// ... somewhere in code
foo ();
static void foo ()
{
// do sth
}
Spring MVC offers a standaloneSetup that supports testing relatively simple controllers, without the need of context.
Build a MockMvc by registering one or more @Controller's instances and configuring Spring MVC infrastructure programmatically. This allows full control over the instantiation and initialization of controllers, and their dependencies, similar to plain unit tests while also making it possible to test one controller at a time.
An example test for your controller can be something as simple as
public class DemoApplicationTests {
private MockMvc mockMvc;
@Before
public void setup() {
this.mockMvc = standaloneSetup(new HelloWorld()).build();
}
@Test
public void testSayHelloWorld() throws Exception {
this.mockMvc.perform(get("/")
.accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
.andExpect(status().isOk())
.andExpect(content().contentType("application/json"));
}
}
I recently posted a free software library for this: "html5csv.js" -- GitHub
It is intended to help streamline the creation of small simulator apps in Javascript that might need to import or export csv files, manipulate, display, edit the data, perform various mathematical procedures like fitting, etc.
After loading "html5csv.js" the problem of scanning a table and creating a CSV is a one-liner:
CSV.begin('#PrintDiv').download('MyData.csv').go();
Here is a JSFiddle demo of your example with this code.
Internally, for Firefox/Chrome this is a data URL oriented solution, similar to that proposed by @italo, @lepe, and @adeneo (on another question). For IE
The CSV.begin()
call sets up the system to read the data into an internal array. That fetch then occurs. Then the .download()
generates a data URL link internally and clicks it with a link-clicker. This pushes a file to the end user.
According to caniuse IE10 doesn't support <a download=...>
. So for IE my library calls navigator.msSaveBlob()
internally, as suggested by @Manu Sharma
To Enter into crontab :
crontab -e
write this into the file:
0 */2 * * * python/php/java yourfilepath
Example :0 */2 * * * python ec2-user/home/demo.py
and make sure you have keep one blank line after the last cron job in your crontab file
An alternative is to use line-height
:
http://jsfiddle.net/DjT37/
.bigbox{
height:40px;
line-height:40px;
padding:0 5px;
}
This tends to be more consistent when you want a specific height as you don't need to calculate padding based on font-size and desired height, etc.
The javadoc of the File
class describes the class as:
An abstract representation of file and directory pathnames.
File
is only a representation of a pathname, with a few methods concerning the filesystem (like exists()
) and directory handling but actual streaming input and output is done elsewhere. Streams can be opened and closed, files cannot.
(My personal opinion is that it's rather unfortunate that Sun then went on to create RandomAccessFile
, causing much confusion with its inconsistent naming.)
Try this:
<div id="wrapper">
<div class="float left">left</div>
<div class="float right">right</div>
</div>
#wrapper {
width:500px;
height:300px;
position:relative;
}
.float {
background-color:black;
height:300px;
margin:0;
padding:0;
color:white;
}
.left {
background-color:blue;
position:fixed;
width:400px;
}
.right {
float:right;
width:100px;
}

You could also be more restrictive in removing disallowed characters. The following regex would remove all characters that are not letters, digits or underscores:
$FileName = preg_replace('/[^\w]/', '', $UserInput);
You might want to do this to ensure maximum compatibility for filenames across different operating systems.
I use FluentIterable.from(myIterable).toList()
a lot.
You don't need pip
for installing Beautiful Soup - you can just download it and run python setup.py install
from the directory that you have unzipped BeautifulSoup in (assuming that you have added Python to your system PATH
- if you haven't and you don't want to you can run C:\Path\To\Python27\python "C:\Path\To\BeautifulSoup\setup.py" install
)
However, you really should install pip
- see How to install pip on Windows for how to do that best (via @MartijnPieters comment)
The data.table
package also has unique
and duplicated
methods of it's own with some additional features.
Both the unique.data.table
and the duplicated.data.table
methods have an additional by
argument which allows you to pass a character
or integer
vector of column names or their locations respectively
library(data.table)
DT <- data.table(id = c(1,1,1,2,2,2),
val = c(10,20,30,10,20,30))
unique(DT, by = "id")
# id val
# 1: 1 10
# 2: 2 10
duplicated(DT, by = "id")
# [1] FALSE TRUE TRUE FALSE TRUE TRUE
Another important feature of these methods is a huge performance gain for larger data sets
library(microbenchmark)
library(data.table)
set.seed(123)
DF <- as.data.frame(matrix(sample(1e8, 1e5, replace = TRUE), ncol = 10))
DT <- copy(DF)
setDT(DT)
microbenchmark(unique(DF), unique(DT))
# Unit: microseconds
# expr min lq mean median uq max neval cld
# unique(DF) 44708.230 48981.8445 53062.536 51573.276 52844.591 107032.18 100 b

I know this has already been answered, but here is an example for the people who are trying to use SQL Server Types in a vb project:
Imports System
Imports System.IO
Imports System.Runtime.InteropServices
Namespace SqlServerTypes
Public Class Utilities
<DllImport("kernel32.dll", CharSet:=CharSet.Auto, SetLastError:=True)>
Public Shared Function LoadLibrary(ByVal libname As String) As IntPtr
End Function
Public Shared Sub LoadNativeAssemblies(ByVal rootApplicationPath As String)
Dim nativeBinaryPath = If(IntPtr.Size > 4, Path.Combine(rootApplicationPath, "SqlServerTypes\x64\"), Path.Combine(rootApplicationPath, "SqlServerTypes\x86\"))
LoadNativeAssembly(nativeBinaryPath, "msvcr120.dll")
LoadNativeAssembly(nativeBinaryPath, "SqlServerSpatial140.dll")
End Sub
Private Shared Sub LoadNativeAssembly(ByVal nativeBinaryPath As String, ByVal assemblyName As String)
Dim path = System.IO.Path.Combine(nativeBinaryPath, assemblyName)
Dim ptr = LoadLibrary(path)
If ptr = IntPtr.Zero Then
Throw New Exception(String.Format("Error loading {0} (ErrorCode: {1})", assemblyName, Marshal.GetLastWin32Error()))
End If
End Sub

The problem is with the way you are printing the Time data
java.util.Date utilDate = new java.util.Date();
java.sql.Timestamp sq = new java.sql.Timestamp(utilDate.getTime());
System.out.println(sa); //this will print the milliseconds as the toString() has been written in that format
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(sdf.format(timestamp)); //this will print without ms
These steps work for me:
You can also get your wanted time using the following JS code:
new Date(`${post.data.created_at} GMT+0200`)
In this example, my received dates were in GMT+0200 timezone. Instead of it can be every single timezone. And the returned data will be the date in your timezone. Hope this will help anyone to save time
Signing is producing a "hash" with your private key that can be verified with your public key. The text is sent in the clear.
Encrypting uses the receiver's public key to encrypt the data; decoding is done with their private key.
So, the use of keys is not reversed (otherwise your private key wouldn't be private anymore!).
Do this way:-
var peoples = [
{ "name": "bob", "dinner": "pizza" },
{ "name": "john", "dinner": "sushi" },
{ "name": "larry", "dinner": "hummus" }
];
$.each(peoples, function(i, val) {
$.each(val, function(key, name) {
if (name === "john")
alert(key + " : " + name);
});
});
name : john

I know this is a little late, but I just figured out how to do this by modifying (read, "hacking") the manifest of the devenv.exe file. I should have come here first because the stated solutions seem a little easier, and probably more supported by Microsoft. :)
Here's how I did it:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false"></requestedExecutionLevel>
You've just saved the copy of the executable that was added to your project. Now you need to back up the original and copy your modified exe to your installation directory.
As I said, this is probably not the right way to do it, but it seems to work. If anyone knows of any negative fallout or requisite wrist-slapping that needs to happen, please chime in!
Quick hack:
def dowhile(func = None, condition = None):
if not func or not condition:
return
else:
func()
while condition():
func()
Use like so:
>>> x = 10
>>> def f():
... global x
... x = x - 1
>>> def c():
global x
return x > 0
>>> dowhile(f, c)
>>> print x
0
According to this :
SmtpClient and its network of types are poorly designed, we strongly recommend you use https://github.com/jstedfast/MailKit and https://github.com/jstedfast/MimeKit instead.
Reference : https://docs.microsoft.com/en-us/dotnet/api/system.net.mail.smtpclient?view=netframework-4.8
It's better to use MailKit
to send emails :
var message = new MimeMessage ();
message.From.Add (new MailboxAddress ("Joey Tribbiani", "[email protected]"));
message.To.Add (new MailboxAddress ("Mrs. Chanandler Bong", "[email protected]"));
message.Subject = "How you doin'?";
message.Body = new TextPart ("plain") {
Text = @"Hey Chandler,
I just wanted to let you know that Monica and I were going to go play some paintball, you in?
-- Joey"
};
using (var client = new SmtpClient ()) {
// For demo-purposes, accept all SSL certificates (in case the server supports STARTTLS)
client.ServerCertificateValidationCallback = (s,c,h,e) => true;
client.Connect ("smtp.friends.com", 587, false);
// Note: only needed if the SMTP server requires authentication
client.Authenticate ("joey", "password");
client.Send (message);
client.Disconnect (true);
}
Works perfectly fine if the first option's value is null. Explanation : The HTML5 will read a null value on button submit. If not null (value attribute), the selected value is assumed not to be null hence the validation would have worked i.e by checking if there's been data in the option tag. Therefore it will not produce the validation method. However, i guess the other side becomes clear, if the value attribute is set to null ie (value = "" ), HTML5 will detect an empty value on the first or rather the default selected option thus giving out the validation message. Thanks for asking. Happy to help. Glad to know if i did.
Use:
find . 2>/dev/null > files_and_folders
This hides not just the Permission denied
errors, of course, but all error messages.
If you really want to keep other possible errors, such as too many hops on a symlink, but not the permission denied ones, then you'd probably have to take a flying guess that you don't have many files called 'permission denied' and try:
find . 2>&1 | grep -v 'Permission denied' > files_and_folders
If you strictly want to filter just standard error, you can use the more elaborate construction:
find . 2>&1 > files_and_folders | grep -v 'Permission denied' >&2
The I/O redirection on the find
command is: 2>&1 > files_and_folders |
.
The pipe redirects standard output to the grep
command and is applied first. The 2>&1
sends standard error to the same place as standard output (the pipe). The > files_and_folders
sends standard output (but not standard error) to a file. The net result is that messages written to standard error are sent down the pipe and the regular output of find
is written to the file. The grep
filters the standard output (you can decide how selective you want it to be, and may have to change the spelling depending on locale and O/S) and the final >&2
means that the surviving error messages (written to standard output) go to standard error once more. The final redirection could be regarded as optional at the terminal, but would be a very good idea to use it in a script so that error messages appear on standard error.
There are endless variations on this theme, depending on what you want to do. This will work on any variant of Unix with any Bourne shell derivative (Bash, Korn, …) and any POSIX-compliant version of find
.
If you wish to adapt to the specific version of find
you have on your system, there may be alternative options available. GNU find
in particular has a myriad options not available in other versions — see the currently accepted answer for one such set of options.
I had the same error on OS X (node v6.2.0 and npm v3.9.3 installed with homebrew) and it was not solved by any of the above. I had to add full paths to the commands being run by concurrently.
In package.json, I changed this:
"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",
to this:
"start": "tsc && concurrently \"/Users/kyen/.node/bin/npm run tsc:w\" \"/Users/kyen/.node/bin/npm run lite\" ",
You will, of course, need to update the correct paths based on where your node global binaries are stored. Note that I didn't need to add the path to the first tsc command. It seems only concurrently needs the full paths specified.
${project.basedir}
is the root directory of your project.
${project.build.directory}
is equivalent to ${project.basedir}/target
as it is defined here: https://github.com/apache/maven/blob/trunk/maven-model-builder/src/main/resources/org/apache/maven/model/pom-4.0.0.xml#L53
here is one that work with both " and ' and you easily add others at the start.
("|')(?:\\\1|[^\1])*?\1
it uses the backreference (\1) match exactley what is in the first group (" or ').
To run batch files using java if that's you're talking about...
String path="cmd /c start d:\\sample\\sample.bat";
Runtime rn=Runtime.getRuntime();
Process pr=rn.exec(path);`
This should do it.
If you associate default functions for (sub)parsers, as is mentioned under add_subparsers
, you can simply add it as the default action:
parser = argparse.ArgumentParser()
parser.set_defaults(func=lambda x: parser.print_usage())
args = parser.parse_args()
args.func(args)
Add the try-except if you raise exceptions due to missing positional arguments.
To just get your IP address:
echo `ifconfig eth0 2>/dev/null|awk '/inet addr:/ {print $2}'|sed 's/addr://'`
This will give you the IP address of eth0.
Edit: Due to name changes of interfaces in recent versions of Ubuntu, this doesn't work anymore. Instead, you could just use this:
hostname --all-ip-addresses
or hostname -I
, which does the same thing (gives you ALL IP addresses of the host).
The only reason to have a return in a void function would be to exit early due to some conditional statement:
void foo(int y)
{
if(y == 0) return;
// do stuff with y
}
As unwind said: when the code ends, it ends. No need for an explicit return at the end.
You should create a startup.bat
if you're using Windows, much more convenient:
C:\mongodb\mongodb-win32-x86_64-eiditon\bin\mongod.exe --dbpath C:\mongodb\data
And just dbclick startup.bat and mongodb will run using C:\mongodb\data
as its data folder.
Two problems:
Your function does not return anything; a function that does not explicitly return anything returns None (which is falsy)
True is always True - you are not checking the result of your function
.
def check(fname, txt):
with open(fname) as dataf:
return any(txt in line for line in dataf)
if check('example.txt', 'blabla'):
print "true"
else:
print "false"
If you are new to Active Directory, I suggest you should understand how Active Directory stores data first.
Active Directory is actually a LDAP server. Objects stored in LDAP server are stored hierarchically. It's very similar to you store your files in your file system. That's why it got the name Directory server and Active Directory
The containers and objects on Active Directory can be specified by a distinguished name
. The distinguished name is like this CN=SomeName,CN=SomeDirectory,DC=yourdomain,DC=com
. Like a traditional relational database, you can run query against a LDAP server. It's called LDAP query.
There are a number of ways to run a LDAP query in .NET. You can use DirectorySearcher from System.DirectoryServices
or SearchRequest from System.DirectoryServices.Protocol
.
For your question, since you are asking to find user principal object specifically, I think the most intuitive way is to use PrincipalSearcher from System.DirectoryServices.AccountManagement
. You can easily find a lot of different examples from google. Here is a sample that is doing exactly what you are asking for.
using (var context = new PrincipalContext(ContextType.Domain, "yourdomain.com"))
{
using (var searcher = new PrincipalSearcher(new UserPrincipal(context)))
{
foreach (var result in searcher.FindAll())
{
DirectoryEntry de = result.GetUnderlyingObject() as DirectoryEntry;
Console.WriteLine("First Name: " + de.Properties["givenName"].Value);
Console.WriteLine("Last Name : " + de.Properties["sn"].Value);
Console.WriteLine("SAM account name : " + de.Properties["samAccountName"].Value);
Console.WriteLine("User principal name: " + de.Properties["userPrincipalName"].Value);
Console.WriteLine();
}
}
}
Console.ReadLine();
Note that on the AD user object, there are a number of attributes. In particular, givenName
will give you the First Name
and sn
will give you the Last Name
. About the user name. I think you meant the user logon name. Note that there are two logon names on AD user object. One is samAccountName
, which is also known as pre-Windows 2000 user logon name. userPrincipalName
is generally used after Windows 2000.
How about using some Sass? Here's what I did to achieve something like this (although note that you have to create a Sass list for each of the data-attributes).
/*
Iterate over list and use "data-social" to put in the appropriate background-image.
*/
$social: "fb", "twitter", "youtube";
@each $i in $social {
[data-social="#{$i}"] {
background: url('#{$image-path}/icons/#{$i}.svg') no-repeat 0 0;
background-size: cover; // Only seems to work if placed below background property
}
}
Essentially, you list all of your data attribute values. Then use Sass @each to iterate through and select all the data-attributes in the HTML. Then, bring in the iterator variable and have it match up to a filename.
Anyway, as I said, you have to list all of the values, then make sure that your filenames incorporate the values in your list.
You can make <button>
tag to do action like this:
<a href="http://www.google.com/">
<button>Visit Google</button>
</a>
or:
<a href="http://www.google.com/">
<input type="button" value="Visit Google" />
</a>
It's simple and no javascript required!
NOTE:
This approach is not valid from HTML structure. But, it works on many modern browser. See following reference :
Hexidecimal to decimal:
$ echo $((0xfee10000))

Decimal to hexadecimal:
$ printf '%x\n' 26
