$url = "https://chart.googleapis....";
$json = file_get_contents($url);
Now you can either echo the $json variable, if you just want to display the output, or you can decode it, and do something with it, like so:
$data = json_decode($json);
var_dump($data);
An easy alternative that works for me is to insert the svg code into a div. This simple example uses javascript to manipulate the div innerHTML.
svg = '<svg height=150>';
svg+= '<rect height=100% fill=green /><circle cx=150 cy=75 r=60 fill=yellow />';
svg+= '<text x=150 y=95 font-size=60 text-anchor=middle fill=red>IIIIIII</text></svg>';
document.all.d1.innerHTML=svg;
_x000D_
<div id='d1' style="float:right;"></div><hr>
_x000D_

My Visual Studio 2015 RTM was also very slow using ReSharper 9.1.2, but it has worked fine since I upgraded to 9.1.3 (see ReSharper 9.1.3 to the Rescue). Perhaps a cue.
One more cue. A ReSharper 9.2 version was made available to:

Awk approach:
awk '/pattern/{print; count++; if (count==10) exit}' file
You can use extension method:
namespace extension
{
public class ext
{
public static List<double> clone(this List<double> t)
{
List<double> kop = new List<double>();
int x;
for (x = 0; x < t.Count; x++)
{
kop.Add(t[x]);
}
return kop;
}
};
}
You can clone all objects by using their value type members for example, consider this class:
public class matrix
{
public List<List<double>> mat;
public int rows,cols;
public matrix clone()
{
// create new object
matrix copy = new matrix();
// firstly I can directly copy rows and cols because they are value types
copy.rows = this.rows;
copy.cols = this.cols;
// but now I can no t directly copy mat because it is not value type so
int x;
// I assume I have clone method for List<double>
for(x=0;x<this.mat.count;x++)
{
copy.mat.Add(this.mat[x].clone());
}
// then mat is cloned
return copy; // and copy of original is returned
}
};
Note: if you do any change on copy (or clone) it will not affect the original object.
Besides the solution of m79lkm above, my 2 cents on this topic is not to directly pipe the result in gzip but first dump it as a .sql file, and then gzip it. (Use && instead of | )
The dump itself will be faster. (for what I tested it was double as fast)
Otherwise you tables will be locked longer and the downtime/slow-responding of your application can bother the users. The mysqldump command is taking a lot of resources from your server.
So I would go for "&& gzip" instead of "| gzip"
Important: check for free disk space first with df -h
since you will need more then piping | gzip.
mysqldump -u user -p[user_password] [database_name] > dumpfilename.sql && gzip dumpfilename.sql
-> which will also result in 1 file called dumpfilename.sql.gz
Furthermore the option --single-transaction
prevents the tables being locked but still result in a solid backup. So you might consider to use that option. See docs here
mysqldump --single-transaction -u user -p[user_password] [database_name] > dumpfilename.sql && gzip dumpfilename.sql
The one major thing I think people are leaving out is that Build and Clean are both tasks that are performed based on Visual Studio's knowledge of your Project/Solution. I see a lot of complaining that Clean doesn't work or leaves leftover files or is not trustworthy, when in fact, the reasons you say it isn't trustworthy actually makes it more trustworthy.
Clean will only remove (clean) files and/or directories that Visual Studio or the compiler themselves have in fact created. If you copy your own files or files/folder structures get created from an outside tool or source, then Visual Studio doesn't "know they exist" and therefore, should not touch them.
Can you imagine if the Clean operation basically performed a "del *.*" ? This could be catastrophic.
Build performs a compile on changed or necessary projects.
Rebuild performs a compile regardless of change or what's necessary.
Clean removes files/folders it has created in the past, but leaves anything that it didn't have anything to do with, initially.
I hope this elaborates a bit and helps.
Change from @Controller to @Service to CompteController and add @Service annotation to CompteDAOHib. Let me know if you still face this issue.
There is always sys.exit()
.
The system library in Python's core library has an exit function which is super handy when prototyping. The code would be along the lines of:
import sys
while True:
selection = raw_input("U: Create User\nQ: Quit")
if selection is "Q" or selection is "q":
print("Quitting")
sys.exit()
if selection is "U" or selection is "u":
print("User")
#do_something()
There can be multiple root causes for this exception. For me, my mockMvc wasn't getting auto-configured. I solved this exception by using @WebMvcTest(MyController.class)
at the class level. This annotation will disable full auto-configuration and instead apply only configuration relevant to MVC tests.
An alternative to this is, If you are looking to load your full application configuration and use MockMVC, you should consider @SpringBootTest
combined with @AutoConfigureMockMvc
rather than @WebMvcTest
Pointers are not always the same size on the same architecture.

There is an excellent answer from Orwellophile, which does include a pure bash option (function rawurlencode), which I've used on my website (shell based CGI script, large number of URLS in response to search requests). The only draw back was high CPU during peak time.
I've found a modified solution, leverage bash "global replace" feature. With this solution processing time for url encode is 4X faster. The solution identify the characters to be escaped, and uses the "global replace" operator (${var//source/replacement}) to process all substitutions. The speed up is clearly from using bash internal loops, over explicit loop.
Performance: On core i3-8100 3.60Ghz. Test case: 1000 URL from stack overflow, similar to this ticket: "https://stackoverflow.com/questions/296536/how-to-urlencode-data-for-curl-command".
url_encode()
{
local key="${1}" varname="${2:-_rval}" prefix="${3:-_ENCKEY_}"
local unsafe=${key//[-_.~a-zA-Z0-9 ]/}
local -i key_len=${#unsafe}
local ch ch1 ch0
while [ "$unsafe" ] ;do
ch=${unsafe:0:1}
ch0="\\$ch"
printf -v ch1 '%%%02x' "'$ch'"
key=${key//$ch0/"$ch1"}
unsafe=${unsafe//"$ch0"}
done
key=${key// /+}
REPLY="$key"
# printf "%s" "$REPLY"
return 0
}
As a minor extra, it uses '+' to encode the space. Slightly more compact URL.
Benchmark:
function t {
local key
for (( i=1 ; i<=$1 ; i++ )) do url_encode "$2" kkk2 ; done
echo "K=$REPLY"
}
t 1000 "https://stackoverflow.com/questions/296536/how-to-urlencode-data-for-curl-command"
Just one more hint. If you need real URL (to support browser accessibility) you can do the following:
template:
<a ng-href="{{link}}" ng-click="$event.preventDefault(); linkClicked(link)">{{link}}</a>
directive:
$scope.linkClicked = function(link){
// your code here
$location.path(link);
};
In this way your code in linkClicked() will have chance to execute before navigating to the link
I was facing the same issue but I switched 26.0.0-beta1 dependencies to 26.1.0 and it's working now.

Why aren't you using a Long Press? Or are you using that already for something else? The advantages of a Long Press over a Double Touch:
No, absolutely not - because if acct
is null, it won't even get to isEmpty
... it will immediately throw a NullPointerException
.
Your test should be:
if (acct != null && !acct.isEmpty())
Note the use of &&
here, rather than your ||
in the previous code; also note how in your previous code, your conditions were wrong anyway - even with &&
you would only have entered the if
body if acct
was an empty string.
Alternatively, using Guava:
if (!Strings.isNullOrEmpty(acct))
I have this error while I tried to use JDK 1.7. When I upgraded my JDK to jdk1.8.0_66 all started to work fine.
So the simplest solution for this problem could be - upgrade your JDK and it could start to work well.
In Android Studio, go to app -> src -> main -> java -> com.example.username.projectname
Right click on com.example.username.projectname -> Activity -> ActivityType
Fill in the details of the New Android Activity and click Finish.
Viola! new activity added to the existing project.
In my case since the default varies from case to case in the form. I add a custom attribute in the select tag.
<select setSeletected="{{data.value}}">
<option value="value1"> value1....
<option value="value2"> value2....
......
in the directives I created a script that checks the value and when angular fills it in sets the option with that value to selected.
.directive('setSelected', function(){
restrict: 'A',
link: (scope, element, attrs){
function setSel=(){
//test if the value is defined if not try again if so run the command
if (typeof attrs.setSelected=='undefined'){
window.setTimeout( function(){setSel()},300)
}else{
element.find('[value="'+attrs.setSelected+'"]').prop('selected',true);
}
}
}
setSel()
})
just translated this from coffescript on the fly at least the jist of it is correct if not the hole thing.
It's not the simplest way but get it done when the value varies

The correct way to use LOCK TABLES and UNLOCK TABLES with transactional tables, such as InnoDB tables, is to begin a transaction with SET autocommit = 0 (not START TRANSACTION) followed by LOCK TABLES, and to not call UNLOCK TABLES until you commit the transaction explicitly. For example, if you need to write to table t1 and read from table t2, you can do this:
SET autocommit=0;
LOCK TABLES t1 WRITE, t2 READ, ...;... do something with tables t1 and t2 here ...
COMMIT;
UNLOCK TABLES;
There's one more theoretical possibility to do it: professional versions of Windows have built-in POSIX support, so bash could have been compiled for Windows natively.
Pity, but I still haven't found a compiled one myself...
To check for the existence of a directory using Dir
, you need to specify vbDirectory
as the second argument, as in something like:
If Dir("C:\2013 Recieved Schedules" & "\" & client, vbDirectory) = "" Then
Note that, with vbDirectory
, Dir
will return a non-empty string if the specified path already exists as a directory or as a file (provided the file doesn't have any of the read-only, hidden, or system attributes). You could use GetAttr
to be certain it's a directory and not a file.
Using Function || stateless component
Parent Component
import React from "react";
import ChildComponent from "./childComponent";
export default function Parent(){
const handleParentFun = (value) =>{
console.log("Call to Parent Component!",value);
}
return (<>
This is Parent Component
<ChildComponent
handleParentFun={(value)=>{
console.log("your value -->",value);
handleParentFun(value);
}}
/>
</>);
}
Child Component
import React from "react";
export default function ChildComponent(props){
return(
<> This is Child Component
<button onClick={props.handleParentFun("YoureValue")}>
Call to Parent Component Function
</button>
</>
);
}
In this context components to me sound like isolated runtime portions of an engine that may execute concurrently with other components. If this is the motivation then you might want to look at the actor model and systems that make use of it.
I thought i'd expand on the above answer by talking about how you'd fit modules together into an application. I'd read about this in the doug crockford book but being new to javascript it was all still a bit mysterious.
I come from a c# background so have added some terminology I find useful from there.
Html
You'll have some kindof top level html file. It helps to think of this as your project file. Every javascript file you add to the project wants to go into this, unfortunately you dont get tool support for this (I'm using IDEA).
You need add files to the project with script tags like this:
<script type="text/javascript" src="app/native/MasterFile.js" /></script>
<script type="text/javascript" src="app/native/SomeComponent.js" /></script>
It appears collapsing the tags causes things to fail - whilst it looks like xml it's really something with crazier rules!
Namespace file
MasterFile.js
myAppNamespace = {};
that's it. This is just for adding a single global variable for the rest of our code to live in. You could also declare nested namespaces here (or in their own files).
Module(s)
SomeComponent.js
myAppNamespace.messageCounter= (function(){
var privateState = 0;
var incrementCount = function () {
privateState += 1;
};
return function (message) {
incrementCount();
//TODO something with the message!
}
})();
What we're doing here is assigning a message counter function to a variable in our application. It's a function which returns a function which we immediately execute.
Concepts
I think it helps to think of the top line in SomeComponent as being the namespace where you are declaring something. The only caveat to this is all your namespaces need to appear in some other file first - they are just objects rooted by our application variable.
I've only taken minor steps with this at the moment (i'm refactoring some normal javascript out of an extjs app so I can test it) but it seems quite nice as you can define little functional units whilst avoiding the quagmire of 'this'.
You can also use this style to define constructors by returning a function which returns an object with a collection of functions and not calling it immediately.
My answer is based on comment uniqid user comment but it uses openssl_random_pseudo_bytes function to generate random string instead of reading from /dev/urandom
function guid()
{
$randomString = openssl_random_pseudo_bytes(16);
$time_low = bin2hex(substr($randomString, 0, 4));
$time_mid = bin2hex(substr($randomString, 4, 2));
$time_hi_and_version = bin2hex(substr($randomString, 6, 2));
$clock_seq_hi_and_reserved = bin2hex(substr($randomString, 8, 2));
$node = bin2hex(substr($randomString, 10, 6));
/**
* Set the four most significant bits (bits 12 through 15) of the

*/
$time_hi_and_version = hexdec($time_hi_and_version);
$time_hi_and_version = $time_hi_and_version >> 4;
$time_hi_and_version = $time_hi_and_version | 0x4000;
/**
* Set the two most significant bits (bits 6 and 7) of the

$clock_seq_hi_and_reserved = hexdec($clock_seq_hi_and_reserved);
$clock_seq_hi_and_reserved = $clock_seq_hi_and_reserved >> 2;
$clock_seq_hi_and_reserved = $clock_seq_hi_and_reserved | 0x8000;
return sprintf('%08s-%04s-%04x-%04x-%012s', $time_low, $time_mid, $time_hi_and_version, $clock_seq_hi_and_reserved, $node);

Using MS SQL Server 2012, you need to perform 3 basic steps:
First, generate .sql
file containing only the structure of the source DB
.sql
file locallySecond, replace the source DB with the destination one in the .sql
file
Finally, populate with data
Data Source=Mehdi\SQLEXPRESS;Initial Catalog=db_test;User ID=sa;Password=sqlrpwrd15
You are done.
I was also looking for a solution to this problem and as easy and comfortable I found, was to convert the shape of a rectangular TextView to cirular. With this method will be perfect:
Create a new XML file in the drawable folder called "circle.xml" (for example) and fill it with the following code:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#9FE554" />
<size
android:height="60dp"
android:width="60dp" />
</shape>
With this file you will create the new form of TextView. In this case, I created a circle of green. If you want to add a border, you would have to add the following code to the previous file:
<stroke
android:width="2dp"
android:color="#FFFFFF" />
Create another XML file ( "rounded_textview.xml") in the drawable folder with the following code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/circle" />
</selector>
This file will serve to change the way the TextView we eligamos.
Finally, in the TextView properties we want to change the way section, we headed to the "background" and select the second XML file created ( "rounded_textview.xml").
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="H"
android:textSize="30sp"
android:background="@drawable/rounded_textview"
android:textColor="@android:color/white"
android:gravity="center"
android:id="@+id/mark" />
With these steps, instead of having a TextView TextView rectagular have a circular. Just change the shape, not the functionality of the TextView. The result would be the following:
Also I have to say that these steps can be applied to any other component having the option to "background" in the properties.
Luck!!
I've found you can use a very non verbose and straightforward approach to checking for the existence various SQL Server objects this way:
IF OBJECTPROPERTY (object_id('schemaname.scalarfuncname'), 'IsScalarFunction') = 1
IF OBJECTPROPERTY (object_id('schemaname.tablefuncname'), 'IsTableFunction') = 1
IF OBJECTPROPERTY (object_id('schemaname.procname'), 'IsProcedure') = 1
This is based on the OBJECTPROPERTY function which is available in SQL 2005+. The MSDN article can be found here.
The OBJECTPROPERTY function uses the following signature:
OBJECTPROPERTY ( id , property )
You pass a literal value into the property parameter, designating the type of object you are looking for. There's a massive list of values you can supply.
It seems to have to do with context wrapping. Most classes derived from Context
are actually a ContextWrapper
, which essentially delegates to another context, possibly with changes by the wrapper.
The context is a general abstraction that supports mocking and proxying. Since many contexts are bound to a limited-lifetime object such as an Activity
, there needs to be a way to get a longer-lived context, for purposes such as registering for future notifications. That is achieved by Context.getApplicationContext()
. A logical implementation is to return the global Application
object, but nothing prevents a context implementation from returning a wrapper or proxy with a suitable lifetime instead.
Activities and services are more specifically associated with an Application
object. The usefulness of this, I believe, is that you can create and register in the manifest a custom class derived from Application
and be certain that Activity.getApplication()
or Service.getApplication()
will return that specific object of that specific type, which you can cast to your derived Application
class and use for whatever custom purpose.
In other words, getApplication()
is guaranteed to return an Application
object, while getApplicationContext()
is free to return a proxy instead.
For the better answer, you can use these lines of code. Here is the example maybe help you :
image = cv2.imread('/home/pictures/1.jpg')
plt.imshow(image)
plt.show()
In imread()
you can pass the directory .so you can also use str()
and +
to combine dynamic directories and fixed directory like this:
path = '/home/pictures/'
for i in range(2) :
image = cv2.imread(str(path)+'1.jpg')
plt.imshow(image)
plt.show()
Both are the same.
false != 'false'
For good measures, put the result of validate into a variable to avoid double validation and use that in the IF statement. Like this:
var result = ValidateForm();
if(result == false) {
...
}
It is a broken/very hard to use replacement for the "center" tag. It comes in handy when you need broken tables and non-working centering for blocks and text.
First of all get a string from an EDITTEXT and then convert this string into integer like
String no=myTxt.getText().toString(); //this will get a string
int no2=Integer.parseInt(no); //this will get a no from the string
Yes, see "Loading Page Fragments" on http://api.jquery.com/load/.
In short, you add the selector after the URL. For example:
$('#result').load('ajax/test.html #container');
It's very simple, Try this code as below:
for(var i = 1; i <= 5; i++) {
for(var j = 1; j<= i; j++) {
document.write("*");
}
document.write("<br/>");
}
I prefer this because it prevents a single item list with an empty item if your source string is empty:
IEnumerable<string> namesList =
!string.isNullOrEmpty(names) ? names.Split(',') : Enumerable.Empty<string>();
What are native methods in Java and where should they be used?
Once you see a small example, it becomes clear:
Main.java:
public class Main {
public native int intMethod(int i);
public static void main(String[] args) {
System.loadLibrary("Main");
System.out.println(new Main().intMethod(2));
}
}
Main.c:
#include <jni.h>
#include "Main.h"
JNIEXPORT jint JNICALL Java_Main_intMethod(
JNIEnv *env, jobject obj, jint i) {
return i * i;
}
Compile and run:
javac Main.java
javah -jni Main
gcc -shared -fpic -o libMain.so -I${JAVA_HOME}/include \
-I${JAVA_HOME}/include/linux Main.c
java -Djava.library.path=. Main

It's syntactically correct and stylistically okay.
Good style requires every case:
statement should end with one of the following:
break;
continue;
return (x);
exit (x);
throw (x);
//fallthrough
Additionally, following case (x):
immediately with
case (y):
default:
is permissible - bundling several cases that have exactly the same effect.
Anything else is suspected to be a mistake, just like if(a=4){...}
Of course you need enclosing loop (while
, for
, do...while
) for continue
to work. It won't loop back to case()
alone. But a construct like:
while(record = getNewRecord())
{
switch(record.type)
{
case RECORD_TYPE_...;
...
break;
default: //unknown type
continue; //skip processing this record altogether.
}
//...more processing...
}
...is okay.
If you want to update it later, once "this" no longer references it, I had some luck with assigning a variable to point to the main form.
static Form f0;
public OrdUpdate()
{
InitializeComponent();
f0=this;
}
// then later you can say
f0.Text="New text";
You can cheat a little with OPENROWSET :
SELECT ...fieldlist...
FROM OPENROWSET('SQLNCLI', 'connection string', 'name of sp')
WHERE ...
This would still run the entire SP every time, of course.

Though this has already been answered, I came from a non-android project and found this, but it could not solve my issue. If someone does see this error, delete the "build" folder manually through your file manager. For me, this repaired the code failing to compile in Kotlin.
To old files I don't know how to do it... I think you will need a script to go thru all files and add the header.
To change the new ones you can do this.
Go to Eclipse menu bar
/**
${user}
*/
And it's done every new File will have your name on it !
For checking spaces just with bash:
[[ "$str" = "${str% *}" ]] && echo "no spaces" || echo "has spaces"
You can't use $(this)
since jQuery doesn't know what it is there. You seem to be overcomplicating things. You can do $('#content h1.aktiv').hide()
. There's no reason to test to see if the class exists.
include Jquery and Jquery UI plugins and try this
$("#LeftSidePane").toggle('slide','left',400);
If I understand your questions correctly, all you need to do is add the .Where(m => m.r.u.UserId == 1):
var UserInRole = db.UserProfiles.
Join(db.UsersInRoles, u => u.UserId, uir => uir.UserId,
(u, uir) => new { u, uir }).
Join(db.Roles, r => r.uir.RoleId, ro => ro.RoleId, (r, ro) => new { r, ro })
.Where(m => m.r.u.UserId == 1)
.Select (m => new AddUserToRole
{
UserName = m.r.u.UserName,
RoleName = m.ro.RoleName
});
Hope that helps.
You can't use {{}}
when using angular directives for binding with ng-model
but for binding non-angular attributes you would have to use {{}}
..
Eg:
ng-show="my-model"

My issue was that viewWillAppear was not called when unwinding from a segue. The answer was to put a call to viewWillAppear(true) in the unwind segue in the View Controller that you segueing back to
@IBAction func unwind(for unwindSegue: UIStoryboardSegue, ViewController subsequentVC: Any) {
viewWillAppear(true)
}

Although almost every possible way has been listed in (at least one of) the existing answers (e.g. Python 3.4 specific stuff was added), I'll try to group everything together.
Note: every piece of Python standard library code that I'm going to post, belongs to version 3.5.3.
Problem statement:
Possible solutions:
[Python 3]: os.path.exists(path) (also check other function family members like os.path.isfile
, os.path.isdir
, os.path.lexists
for slightly different behaviors)
os.path.exists(path)
Return
True
if path refers to an existing path or an open file descriptor. ReturnsFalse
for broken symbolic links. On some platforms, this function may returnFalse
if permission is not granted to execute os.stat() on the requested file, even if the path physically exists.
All good, but if following the import tree:
os.path
- posixpath.py (ntpath.py)
genericpath.py, line ~#20+
def exists(path):
"""Test whether a path exists. Returns False for broken symbolic links"""
try:
st = os.stat(path)
except os.error:
return False
return True
it's just a try / except block around [Python 3]: os.stat(path, *, dir_fd=None, follow_symlinks=True). So, your code is try / except free, but lower in the framestack there's (at least) one such block. This also applies to other funcs (including os.path.isfile
).
1.1. [Python 3]: Path.is_file()
Under the hood, it does exactly the same thing (pathlib.py, line ~#1330):
def is_file(self):
"""
Whether this path is a regular file (also True for symlinks pointing
to regular files).
"""
try:
return S_ISREG(self.stat().st_mode)
except OSError as e:
if e.errno not in (ENOENT, ENOTDIR):
raise
# Path doesn't exist or is a broken symlink
# (see https://bitbucket.org/pitrou/pathlib/issue/12/)
return False
[Python 3]: With Statement Context Managers. Either:
Create one:
class Swallow: # Dummy example
swallowed_exceptions = (FileNotFoundError,)
def __enter__(self):
print("Entering...")
def __exit__(self, exc_type, exc_value, exc_traceback):
print("Exiting:", exc_type, exc_value, exc_traceback)
return exc_type in Swallow.swallowed_exceptions # only swallow FileNotFoundError (not e.g. TypeError - if the user passes a wrong argument like None or float or ...)
And its usage - I'll replicate the os.path.isfile
behavior (note that this is just for demonstrating purposes, do not attempt to write such code for production):
import os
import stat
def isfile_seaman(path): # Dummy func
result = False
with Swallow():
result = stat.S_ISREG(os.stat(path).st_mode)
return result
Use [Python 3]: contextlib.suppress(*exceptions) - which was specifically designed for selectively suppressing exceptions
But, they seem to be wrappers over try / except / else / finally blocks, as [Python 3]: The with statement states:
This allows common try...except...finally usage patterns to be encapsulated for convenient reuse.
Filesystem traversal functions (and search the results for matching item(s))
[Python 3]: os.listdir(path='.') (or [Python 3]: os.scandir(path='.') on Python v3.5+, backport: [PyPI]: scandir)
Under the hood, both use:
via [GitHub]: python/cpython - (master) cpython/Modules/posixmodule.c
Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.
os.listdir
(os.scandir
when available)glob.glob
)
os.listdir
Since these iterate over folders, (in most of the cases) they are inefficient for our problem (there are exceptions, like non wildcarded globbing - as @ShadowRanger pointed out), so I'm not going to insist on them. Not to mention that in some cases, filename processing might be required.
[Python 3]: os.access(path, mode, *, dir_fd=None, effective_ids=False, follow_symlinks=True) whose behavior is close to os.path.exists
(actually it's wider, mainly because of the 2nd argument)
...test if the invoking user has the specified access to path. mode should be F_OK to test the existence of path...
os.access("/tmp", os.F_OK)
Since I also work in C, I use this method as well because under the hood, it calls native APIs (again, via "${PYTHON_SRC_DIR}/Modules/posixmodule.c"), but it also opens a gate for possible user errors, and it's not as Pythonic as other variants. So, as @AaronHall rightly pointed out, don't use it unless you know what you're doing:
Note: calling native APIs is also possible via [Python 3]: ctypes - A foreign function library for Python, but in most cases it's more complicated.
(Win specific): Since vcruntime* (msvcr*) .dll exports a [MS.Docs]: _access, _waccess function family as well, here's an example:
Python 3.5.3 (v3.5.3:1880cb95a742, Jan 16 2017, 16:02:32) [MSC v.1900 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import os, ctypes >>> ctypes.CDLL("msvcrt")._waccess(u"C:\\Windows\\System32\\cmd.exe", os.F_OK) 0 >>> ctypes.CDLL("msvcrt")._waccess(u"C:\\Windows\\System32\\cmd.exe.notexist", os.F_OK) -1
Notes:
os.F_OK
in the call, but that's just for clarity (its value is 0)
The Lnx (Ubtu (16 x64)) counterpart as well:
Python 3.5.2 (default, Nov 17 2016, 17:05:23) [GCC 5.4.0 20160609] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import os, ctypes >>> ctypes.CDLL("/lib/x86_64-linux-gnu/libc.so.6").access(b"/tmp", os.F_OK) 0 >>> ctypes.CDLL("/lib/x86_64-linux-gnu/libc.so.6").access(b"/tmp.notexist", os.F_OK) -1
Notes:
Instead hardcoding libc's path ("/lib/x86_64-linux-gnu/libc.so.6") which may (and most likely, will) vary across systems, None (or the empty string) can be passed to CDLL constructor (ctypes.CDLL(None).access(b"/tmp", os.F_OK)
). According to [man7]: DLOPEN(3):
If filename is NULL, then the returned handle is for the main program. When given to dlsym(), this handle causes a search for a symbol in the main program, followed by all shared objects loaded at program startup, and then all shared objects loaded by dlopen() with the flag RTLD_GLOBAL.
__declspec(dllexport)
(why on Earth the regular person would do that?), the main program is loadable but pretty much unusableInstall some third-party module with filesystem capabilities
Most likely, will rely on one of the ways above (maybe with slight customizations).
One example would be (again, Win specific) [GitHub]: mhammond/pywin32 - Python for Windows (pywin32) Extensions, which is a Python wrapper over WINAPIs.
But, since this is more like a workaround, I'm stopping here.
Another (lame) workaround (gainarie) is (as I like to call it,) the sysadmin approach: use Python as a wrapper to execute shell commands
Win:
(py35x64_test) e:\Work\Dev\StackOverflow\q000082831>"e:\Work\Dev\VEnvs\py35x64_test\Scripts\python.exe" -c "import os; print(os.system('dir /b \"C:\\Windows\\System32\\cmd.exe\" > nul 2>&1'))" 0 (py35x64_test) e:\Work\Dev\StackOverflow\q000082831>"e:\Work\Dev\VEnvs\py35x64_test\Scripts\python.exe" -c "import os; print(os.system('dir /b \"C:\\Windows\\System32\\cmd.exe.notexist\" > nul 2>&1'))" 1
Nix (Lnx (Ubtu)):
[cfati@cfati-ubtu16x64-0:~]> python3 -c "import os; print(os.system('ls \"/tmp\" > /dev/null 2>&1'))" 0 [cfati@cfati-ubtu16x64-0:~]> python3 -c "import os; print(os.system('ls \"/tmp.notexist\" > /dev/null 2>&1'))" 512
Bottom line:
Final note(s):
Uploading Files using Retrofit is Quite Simple You need to build your api interface as
public interface Api {
String BASE_URL = "http://192.168.43.124/ImageUploadApi/";
@Multipart
@POST("yourapipath")
Call<MyResponse> uploadImage(@Part("image\"; filename=\"myfile.jpg\" ") RequestBody file, @Part("desc") RequestBody desc);
}
in the above code image is the key name so if you are using php you will write $_FILES['image']['tmp_name'] to get this. And filename="myfile.jpg" is the name of your file that is being sent with the request.
Now to upload the file you need a method that will give you the absolute path from the Uri.
private String getRealPathFromURI(Uri contentUri) {
String[] proj = {MediaStore.Images.Media.DATA};
CursorLoader loader = new CursorLoader(this, contentUri, proj, null, null, null);
Cursor cursor = loader.loadInBackground();
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String result = cursor.getString(column_index);
cursor.close();
return result;
}
Now you can use the below code to upload your file.
private void uploadFile(Uri fileUri, String desc) {
//creating a file
File file = new File(getRealPathFromURI(fileUri));
//creating request body for file
RequestBody requestFile = RequestBody.create(MediaType.parse(getContentResolver().getType(fileUri)), file);
RequestBody descBody = RequestBody.create(MediaType.parse("text/plain"), desc);
//The gson builder
Gson gson = new GsonBuilder()
.setLenient()
.create();
//creating retrofit object
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Api.BASE_URL)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
//creating our api
Api api = retrofit.create(Api.class);
//creating a call and calling the upload image method
Call<MyResponse> call = api.uploadImage(requestFile, descBody);
//finally performing the call
call.enqueue(new Callback<MyResponse>() {
@Override
public void onResponse(Call<MyResponse> call, Response<MyResponse> response) {
if (!response.body().error) {
Toast.makeText(getApplicationContext(), "File Uploaded Successfully...", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), "Some error occurred...", Toast.LENGTH_LONG).show();
}
}
@Override
public void onFailure(Call<MyResponse> call, Throwable t) {
Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_LONG).show();
}
});
}

You could design your class to be immutable (Effective Java 2nd Ed. has a great section on this, Item 15: Minimize mutability) and make sure upon construction that no nulls are possible (and use the null object pattern if needed). Then you can skip all those checks and safely assume the values are not null.
This solution handles the fact that System.getenv("SECONDARY_STORAGE")
is of no use with Marshmallow.
Tested and working on:
Samsung Galaxy Tab A (Android 6.0.1 - Stock)
/**
* Returns all available external SD-Card roots in the system.
*
* @return paths to all available external SD-Card roots in the system.
*/
public static String[] getStorageDirectories() {
String [] storageDirectories;
String rawSecondaryStoragesStr = System.getenv("SECONDARY_STORAGE");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
List<String> results = new ArrayList<String>();
File[] externalDirs = applicationContext.getExternalFilesDirs(null);
for (File file : externalDirs) {
String path = file.getPath().split("/Android")[0];
if((Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP && Environment.isExternalStorageRemovable(file))
|| rawSecondaryStoragesStr != null && rawSecondaryStoragesStr.contains(path)){
results.add(path);
}
}
storageDirectories = results.toArray(new String[0]);
}else{
final Set<String> rv = new HashSet<String>();
if (!TextUtils.isEmpty(rawSecondaryStoragesStr)) {
final String[] rawSecondaryStorages = rawSecondaryStoragesStr.split(File.pathSeparator);
Collections.addAll(rv, rawSecondaryStorages);
}
storageDirectories = rv.toArray(new String[rv.size()]);
}
return storageDirectories;
}
There is an update to this for Laravel 5.2. Notice this is a slightly different format from what is indicated above.
Begin by installing this package through Composer. Edit your project's composer.json file to require laravelcollective/html.
"require": {
"laravelcollective/html": "5.2.*"
}
Next, update Composer from the Terminal:
composer update
Next, add your new provider to the providers array of config/app.php:
'providers' => [
// ...
Collective\Html\HtmlServiceProvider::class,
// ...
],
Finally, add two class aliases to the aliases array of config/app.php:
'aliases' => [
// ...
'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,
// ...
],
After making this update this code worked for me on a new installation of Laravel 5.2:
{!! Form::open(array('url' => 'foo/bar')) !!}
//
{!! Form::close() !!}
I got this information here: https://laravelcollective.com/docs/5.2/html
Set the default password in the .pgpass file. If the server does not save the password, it is because it is not set in the .pgpass file, or the permissions are open and the file is therefore ignored.
Read more about the password file here.
Also, be sure to check the permissions: on *nix systems the permissions on .pgpass must disallow any access to world or group; achieve this by the command chmod 0600 ~/.pgpass. If the permissions are less strict than this, the file will be ignored.
Have you tried logging-in using PGAdmin? You can save the password there, and modify the pgpass file.
Sometimes you just want a simple one liner:
binary = ''.join(['{0:08b}'.format(ord(x)) for x in input])
Python 3
Seems like you forgot the ["value"] or ->value
:
echo $data[0]->weather->weatherIconUrl[0]->value;
You are trying to access pop as if was a list or a tupple, but pop is not. It's a method.
Getting EXIF data from a JPEG image involves:
Microsoft SQL Server Integration Services (SSIS) is a platform for building high-performance data integration solutions, including extraction, transformation, and load (ETL) packages for data warehousing. SSIS includes graphical tools and wizards for building and debugging packages; tasks for performing workflow functions such as FTP operations, executing SQL statements, and sending e-mail messages; data sources and destinations for extracting and loading data; transformations for cleaning, aggregating, merging, and copying data; a management database, SSISDB, for administering package execution and storage; and application programming interfaces (APIs) for programming the Integration Services object model.
As per Microsoft, the main uses of SSIS Package are:
• Merging Data from Heterogeneous Data Stores Populating Data
• Warehouses and Data Marts Cleaning and Standardizing Data Building
• Business Intelligence into a Data Transformation Process Automating
• Administrative Functions and Data Loading
For developers:
SSIS Package can be integrated with VS development environment for building Business Intelligence solutions. Business Intelligence Development Studio is the Visual Studio environment with enhancements that are specific to business intelligence solutions. It work with 32-bit development environment only.

Creating SSIS ETL Package - Basics :
Sample project of SSIS features in 6 lessons:
You can specify the type of a variable before it to force its type. It's called (dynamic) casting (more information is here):
$string = "1654"
$integer = [int]$string
$string + 1
# Outputs 16541
$integer + 1
# Outputs 1655
As an example, the following snippet adds, to each object in $fileList
, an IntVal
property with the integer value of the Name
property, then sorts $fileList
on this new property (the default is ascending), takes the last (highest IntVal
) object's IntVal
value, increments it and finally creates a folder named after it:
# For testing purposes
#$fileList = @([PSCustomObject]@{ Name = "11" }, [PSCustomObject]@{ Name = "2" }, [PSCustomObject]@{ Name = "1" })
# OR
#$fileList = New-Object -TypeName System.Collections.ArrayList
#$fileList.AddRange(@([PSCustomObject]@{ Name = "11" }, [PSCustomObject]@{ Name = "2" }, [PSCustomObject]@{ Name = "1" })) | Out-Null
$highest = $fileList |
Select-Object *, @{ n = "IntVal"; e = { [int]($_.Name) } } |
Sort-Object IntVal |
Select-Object -Last 1
$newName = $highest.IntVal + 1
New-Item $newName -ItemType Directory
Sort-Object IntVal
is not needed so you can remove it if you prefer.
[int]::MaxValue = 2147483647
so you need to use the [long]
type beyond this value ([long]::MaxValue = 9223372036854775807
).
this.setState({abc: {xyz: 'new value'}});
will NOT work, as state.abc
will be entirely overwritten, not merged.
This works for me:
this.setState((previousState) => {
previousState.abc.xyz = 'blurg';
return previousState;
});
Unless I'm reading the docs wrong, Facebook recommends the above format. https://facebook.github.io/react/docs/component-api.html
Additionally, I guess the most direct way without mutating state is to directly copy by using the ES6 spread/rest operator:
const newState = { ...this.state.abc }; // deconstruct state.abc into a new object-- effectively making a copy
newState.xyz = 'blurg';
this.setState(newState);
As of docker-compose version 3 and later, you can just use the hostname
key:
version: '3'
services:
dns:
hostname: 'your-name'
using (var client = new WebClient())
{
client.DownloadFile("http://example.com/file/song/a.mpeg", "a.mpeg");
}
I had the same issue even when hardware acceleration installed. My solutions was uninstalling and reinstalling it using SDK Manager. Make sure you restart the Android studio after then.
A file object is an instance of Blob but a blob object is not an instance of File
new File([], 'foo.txt').constructor.name === 'File' //true
new File([], 'foo.txt') instanceof File // true
new File([], 'foo.txt') instanceof Blob // true
new Blob([]).constructor.name === 'Blob' //true
new Blob([]) instanceof Blob //true
new Blob([]) instanceof File // false
new File([], 'foo.txt').constructor.name === new Blob([]).constructor.name //false
If you must convert a file object to a blob object, you can create a new Blob object using the array buffer of the file. See the example below.
let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'});
//or let file = document.querySelector('input[type=file]').files[0];
let reader = new FileReader();
reader.onload = function(e) {
let blob = new Blob([new Uint8Array(e.target.result)], {type: file.type });
console.log(blob);
};
reader.readAsArrayBuffer(file);
As pointed by @bgh you can also use the arrayBuffer method of the File object. See the example below.
let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'});
//or let file = document.querySelector('input[type=file]').files[0];
file.arrayBuffer().then((arrayBuffer) => {
let blob = new Blob([new Uint8Array(arrayBuffer)], {type: file.type });
console.log(blob);
});
If your environment supports async/await you can use a one-liner like below
let fileToBlob = async (file) => new Blob([new Uint8Array(await file.arrayBuffer())], {type: file.type });
console.log(await fileToBlob(new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'})));
you can't really know if the user clicked the print
of cancel
button because they both fire the same event onafterprint
or afterprint
which I think is very stupid, why not differentiating between the two events ??
How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:
Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

Ran into this issue. Caused in my case by deleting the .mdf while iispexress was still running and therefor still using the DB. Right click on iisexpress in system tray and click exit THEN delete the MDF to prevent this error from actually occurring.
To fix this error simply within VS right click the App-Data folder add new item > SQL Server Database. Name: [use the database name provided by the update-database error] Click Add.
Pfft! Microseconds! Never solve a problem in microseconds that can be solved in nanoseconds.
Note that the accepted answer:
A better solution is to return True immediately when NAN is found:
import numba
import numpy as np
NAN = float("nan")
@numba.njit(nogil=True)
def _any_nans(a):
for x in a:
if np.isnan(x): return True
return False
@numba.jit
def any_nans(a):
if not a.dtype.kind=='f': return False
return _any_nans(a.flat)
array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M) # 573us
array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M) # 774ns (!nanoseconds)
and works for n-dimensions:
array1M_nd = array1M.reshape((len(array1M)/2, 2))
assert any_nans(array1M_nd)==True
%timeit any_nans(array1M_nd) # 774ns
Compare this to the numpy native solution:
def any_nans(a):
if not a.dtype.kind=='f': return False
return np.isnan(a).any()
array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M) # 456us
array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M) # 470us
%timeit np.isnan(array1M).any() # 532us
The early-exit method is 3 orders or magnitude speedup (in some cases). Not too shabby for a simple annotation.
It works for me, by using double quotes around variables.

First of all, two things that we need to understand,
bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"),
mServiceConn, Context.BIND_AUTO_CREATE);
here mServiceConn
is instance of ServiceConnection
class(inbuilt) it is actually interface
that we need to implement with two (1st for network connected and 2nd network not connected) method to monitor network connection state.
IBinder
Object. So, IBinder
object is our handler which accesses all the methods of Service
by using (.) operator. .
MyService myService;
public ServiceConnection myConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className, IBinder binder) {
Log.d("ServiceConnection","connected");
myService = binder;
}
//binder comes from server to communicate with method's of
public void onServiceDisconnected(ComponentName className) {
Log.d("ServiceConnection","disconnected");
myService = null;
}
}
myservice.serviceMethod();
Here myService
is object and serviceMethod is method in service.
and by this way communication is established between client and server.
Of all of the answers here, I think they either don't work, or they're a bit of a hack (casting back to NSString). It's very likely that the correct answer to this has changed with the different beta releases.
Here is what I use:
let string: String = "hello Swift"
if string.rangeOfString("Swift") != nil
{
println("exists")
}
The "!= nil" became required with Beta 5.
The problem is you are using characters not included in the standard Regex. Use this:
!preg_match("/^[a-z0-9\x{4e00}-\x{9fa5}\:\;\.\,\?\!\@\#\$%\^\*\"\~\'+=\\\ &_\/\.\[\]-\}\{]+$/iu", $str)
As per the comments (and personal experience) you should not modify they Input.php
file — rather, you should create/use your own MY_Input.php
as follows:
<?php
class MY_Input extends CI_Input {
/**
* Clean Keys
*
* This is a helper function. To prevent malicious users
* from trying to exploit keys we make sure that keys are
* only named with alpha-numeric text and a few other items.
*
* Extended to allow:
* - '.' (dot),
* - '[' (open bracket),
* - ']' (close bracket)
*
* @access private
* @param string
* @return string
*/
function _clean_input_keys($str) {
// UPDATE: Now includes comprehensive Regex that can process escaped JSON
if (!preg_match("/^[a-z0-9\:\;\.\,\?\!\@\#\$%\^\*\"\~\'+=\\\ &_\/\.\[\]-\}\{]+$/iu", $str)) {
/**
* Check for Development enviroment - Non-descriptive
* error so show me the string that caused the problem
*/
if (getenv('ENVIRONMENT') && getenv('ENVIRONMENT') == 'DEVELOPMENT') {
var_dump($str);
}
exit('Disallowed Key Characters.');
}
// Clean UTF-8 if supported
if (UTF8_ENABLED === TRUE) {
$str = $this->uni->clean_string($str);
}
return $str;
}
}
// /?/> /* Should never close php file - if you have a space after code, it can mess your life up */
// NOTE: \x{4e00}-\x{9fa5} = allow chinese characters
// NOTE: 'i' — case insensitive
// NOTE: 'u' — UTF-8 mode
if (!preg_match("/^[a-z0-9\x{4e00}-\x{9fa5}\:\;\.\,\?\!\@\#\$%\^\*\"\~\'+=\\\ &_\/\.\[\]-\}\{]+$/iu", $str) { ... }
// NOTE: When Chinese characters are provided in a URL, they are not 'really' there; the browser/OS
// handles the copy/paste -> unicode conversion, eg:
// ??? --> xn--4gqsa60b
// 'punycode' converts these codes according to RFC 3492 and RFC 5891.
// https://github.com/bestiejs/punycode.js --- $ bower install punycode
Here's one way:
if string1.lower() in string2.lower():
...
For this to work, both string1
and string2
objects must be of type string
.
There are multiple ways to write same logic. As it mentioned earlier, you can use object notation or simply expression. However, I think you should not that much logic in HTML. Hard to test and find issue. You can use a getter function to assign the class.
For Instance;
public getCustomCss() {
//Logic here;
if(this.x == this.y){
return 'class1'
}
if(this.x == this.z){
return 'class2'
}
}
<!-- HTML -->
<div [ngClass]="getCustomCss()"> Some prop</div>
//OR
get customCss() {
//Logic here;
if(this.x == this.y){
return 'class1'
}
if(this.x == this.z){
return 'class2'
}
}
<!-- HTML -->
<div [ngClass]="customCss"> Some prop</div>
The only parameter you need right now is ?u=<YOUR_URL>

I had the same issue. I using the standard command for execution. It was calling the X64 ro run against X86 tests. I needed to specify the X86 and not the X64 version of the nunit-runner.
Have a look at the AlertDialog docs. As it states, to add a custom view to your alert dialog you need to find the frameLayout and add your view to that like so:
FrameLayout fl = (FrameLayout) findViewById(android.R.id.custom);
fl.addView(myView, new LayoutParams(MATCH_PARENT, WRAP_CONTENT));
Most likely you are going to want to create a layout xml file for your view, and inflate it:
LayoutInflater inflater = getLayoutInflater();
View twoEdits = inflater.inflate(R.layout.my_layout, f1, false);
With EF or LINQ to SQL:
var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();
With LINQ to Objects I suggest to use morelinq extension MaxBy
(get morelinq from nuget):
var item = items.MaxBy(i => i.Value);
count
is definitely the most concise and efficient way of counting the occurrence of a character in a string but I tried to come up with a solution using lambda
, something like this :
sentence = 'Mary had a little lamb'
sum(map(lambda x : 1 if 'a' in x else 0, sentence))
This will result in :
4
Also, there is one more advantage to this is if the sentence is a list of sub-strings containing same characters as above, then also this gives the correct result because of the use of in
. Have a look :
sentence = ['M', 'ar', 'y', 'had', 'a', 'little', 'l', 'am', 'b']
sum(map(lambda x : 1 if 'a' in x else 0, sentence))
This also results in :
4
But Of-course this will work only when checking occurrence of single character such as 'a'
in this particular case.

EDIT: I wrote a Python script for this.
As your objective is blurring (for privacy protection), you basically need a high recall detector as a first step. Here's how to go about doing this. The included code hints use OpenCV with Python.
Apply Gaussian Blur.
img = cv2.imread('input.jpg',1)
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
img_gray = cv2.GaussianBlur(img_gray, (5,5), 0)
Let the input image be the following.
Threshold the resultant image using strict threshold or OTSU's binarization.
cv2.Sobel(image, -1, 1, 0)
cv2.threshold()
Apply a Morphological Closing operation using suitable structuring element. (I used 16x4 as structuring element)
se = cv2.getStructuringElement(cv2.MORPH_RECT,(16,4))
cv2.morphologyEx(image, cv2.MORPH_CLOSE, se)
Resultant Image after Step 5.
Find external contours of this image.
cv2.findContours(image, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_NONE)
For each contour, find the minAreaRect()
bounding it.
All minAreaRect()
s are shown in orange and the one which satisfies our criteria is in green.
You can apply other filters you deem suitable to increase recall and precision. The detection can also be trained using HOG+SVM to increase precision.
If your color has hex transparency, use the below code.
ImageViewCompat.setImageTintMode(imageView, PorterDuff.Mode.SRC_ATOP);
ImageViewCompat.setImageTintList(imageView, ColorStateList.valueOf(Color.parseColor("#80000000")));
To clear the tint
ImageViewCompat.setImageTintList(imageView, null);
The mobile-first way is to use CSS Columns to create an experience for smaller screens then use Media Queries to increase the number of columns at each of your layout's defined breakpoints.
ul {_x000D_
column-count: 2;_x000D_
column-gap: 2rem;_x000D_
}_x000D_
@media screen and (min-width: 768px)) {_x000D_
ul {_x000D_
column-count: 3;_x000D_
column-gap: 5rem;_x000D_
}_x000D_
}
_x000D_

Stand-alone utility approach
iconv -f ISO-8859-1 -t UTF-8 in.txt > out.txt
-f ENCODING the encoding of the input
-t ENCODING the encoding of the output
You don't have to specify either of these arguments. They will default to your current locale, which is usually UTF-8.
You need to use the fitBounds()
method.
var markers = [];//some array
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < markers.length; i++) {
bounds.extend(markers[i]);
}
map.fitBounds(bounds);
Documentation from developers.google.com/maps/documentation/javascript:
fitBounds(bounds[, padding])
Parameters:
`bounds`: [`LatLngBounds`][1]|[`LatLngBoundsLiteral`][1] `padding` (optional): number|[`Padding`][1]
Return Value: None
Sets the viewport to contain the given bounds.
Note: When the map is set todisplay: none
, thefitBounds
function reads the map's size as0x0
, and therefore does not do anything. To change the viewport while the map is hidden, set the map tovisibility: hidden
, thereby ensuring the map div has an actual size.
This is perfect code but it cannot add a new row:
dataGridView1.Rows[rowIndex].Cells[columnIndex].Value = value;
But this code can insert a new row:
var index = this.dataGridView1.Rows.Add();
this.dataGridView1.Rows[index].Cells[1].Value = "1";
this.dataGridView1.Rows[index].Cells[2].Value = "Baqar";
That depends on what the target server accepts. There is no definitive standard for this. See also a.o. Wikipedia: Query string:
While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field (e.g.
field1=value1&field1=value2&field2=value3
).[4][5]
Generally, when the target server uses a strong typed programming language like Java (Servlet), then you can just send them as multiple parameters with the same name. The API usually offers a dedicated method to obtain multiple parameter values as an array.
foo=value1&foo=value2&foo=value3
String[] foo = request.getParameterValues("foo"); // [value1, value2, value3]
The request.getParameter("foo")
will also work on it, but it'll return only the first value.
String foo = request.getParameter("foo"); // value1
And, when the target server uses a weak typed language like PHP or RoR, then you need to suffix the parameter name with braces []
in order to trigger the language to return an array of values instead of a single value.
foo[]=value1&foo[]=value2&foo[]=value3
$foo = $_GET["foo"]; // [value1, value2, value3]
echo is_array($foo); // true
In case you still use foo=value1&foo=value2&foo=value3
, then it'll return only the first value.
$foo = $_GET["foo"]; // value1
echo is_array($foo); // false
Do note that when you send foo[]=value1&foo[]=value2&foo[]=value3
to a Java Servlet, then you can still obtain them, but you'd need to use the exact parameter name including the braces.
String[] foo = request.getParameterValues("foo[]"); // [value1, value2, value3]
The proper way to run echo "$ENV_VAR"
inside the container so that the variable substitution happens in the container is:
docker exec <container_id> bash -c 'echo "$ENV_VAR"'
<%= link_to "http://www.facebook.com/sharer.php?u=" + article_url(article, :text => article.title), :class => "btn btn-primary" do %> <i class="fa fa-facebook"> Facebook Share </i> <%end%>
I am assuming that current_article_url
is http://0.0.0.0:4567/link_to_title
I did it like this :
// Your JSON
{"event":"forgot password"}
// Your class to map
public class LoggingDto {
@JsonProperty(value = "event")
private FooEnum logType;
}
//Your enum
public enum FooEnum {
DATA_LOG ("Dummy 1"),
DATA2_LOG ("Dummy 2"),
DATA3_LOG ("forgot password"),
DATA4_LOG ("Dummy 4"),
DATA5_LOG ("Dummy 5"),
UNKNOWN ("");
private String fullName;
FooEnum(String fullName) {
this.fullName = fullName;
}
public String getFullName() {
return fullName;
}
@JsonCreator
public static FooEnum getLogTypeFromFullName(String fullName) {
for (FooEnum logType : FooEnum.values()) {
if (logType.fullName.equals(fullName)) {
return logType;
}
}
return UNKNOWN;
}
}
So the value of the property "logType" for class LoggingDto will be DATA3_LOG
The other answers will break if output of command contains spaces (which is rather frequent) or glob characters like *
, ?
, [...]
.
To get the output of a command in an array, with one line per element, there are essentially 3 ways:
With Bash=4 use mapfile
—it's the most efficient:
mapfile -t my_array < <( my_command )
Otherwise, a loop reading the output (slower, but safe):
my_array=()
while IFS= read -r line; do
my_array+=( "$line" )
done < <( my_command )
As suggested by Charles Duffy in the comments (thanks!), the following might perform better than the loop method in number 2:
IFS=$'\n' read -r -d '' -a my_array < <( my_command && printf '\0' )
Please make sure you use exactly this form, i.e., make sure you have the following:
IFS=$'\n'
on the same line as the read
statement: this will only set the environment variable IFS
for the read
statement only. So it won't affect the rest of your script at all. The purpose of this variable is to tell read
to break the stream at the EOL character \n
.-r
: this is important. It tells read
to not interpret the backslashes as escape sequences.-d ''
: please note the space between the -d
option and its argument ''
. If you don't leave a space here, the ''
will never be seen, as it will disappear in the quote removal step when Bash parses the statement. This tells read
to stop reading at the nil byte. Some people write it as -d $'\0'
, but it is not really necessary. -d ''
is better.-a my_array
tells read
to populate the array my_array
while reading the stream.printf '\0'
statement after my_command
, so that read
returns 0
; it's actually not a big deal if you don't (you'll just get an return code 1
, which is okay if you don't use set -e
– which you shouldn't anyway), but just bear that in mind. It's cleaner and more semantically correct. Note that this is different from printf ''
, which doesn't output anything. printf '\0'
prints a null byte, needed by read
to happily stop reading there (remember the -d ''
option?).If you can, i.e., if you're sure your code will run on Bash=4, use the first method. And you can see it's shorter too.
If you want to use read
, the loop (method 2) might have an advantage over method 3 if you want to do some processing as the lines are read: you have direct access to it (via the $line
variable in the example I gave), and you also have access to the lines already read (via the array ${my_array[@]}
in the example I gave).
Note that mapfile
provides a way to have a callback eval'd on each line read, and in fact you can even tell it to only call this callback every N lines read; have a look at help mapfile
and the options -C
and -c
therein. (My opinion about this is that it's a little bit clunky, but can be used sometimes if you only have simple things to do — I don't really understand why this was even implemented in the first place!).
Now I'm going to tell you why the following method:
my_array=( $( my_command) )
is broken when there are spaces:
$ # I'm using this command to test:
$ echo "one two"; echo "three four"
one two
three four
$ # Now I'm going to use the broken method:
$ my_array=( $( echo "one two"; echo "three four" ) )
$ declare -p my_array
declare -a my_array='([0]="one" [1]="two" [2]="three" [3]="four")'
$ # As you can see, the fields are not the lines
$
$ # Now look at the correct method:
$ mapfile -t my_array < <(echo "one two"; echo "three four")
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # Good!
Then some people will then recommend using IFS=$'\n'
to fix it:
$ IFS=$'\n'
$ my_array=( $(echo "one two"; echo "three four") )
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # It works!
But now let's use another command, with globs:
$ echo "* one two"; echo "[three four]"
* one two
[three four]
$ IFS=$'\n'
$ my_array=( $(echo "* one two"; echo "[three four]") )
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="t")'
$ # What?
That's because I have a file called t
in the current directory… and this filename is matched by the glob [three four]
… at this point some people would recommend using set -f
to disable globbing: but look at it: you have to change IFS
and use set -f
to be able to fix a broken technique (and you're not even fixing it really)! when doing that we're really fighting against the shell, not working with the shell.
$ mapfile -t my_array < <( echo "* one two"; echo "[three four]")
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="[three four]")'
here we're working with the shell!
Take a look at this project: http://code.google.com/p/tarlog-plugins/downloads/detail?name=tarlog.eclipse.plugins_1.4.2.jar&can=2&q=
It has some other features, but most importantly, it has Ctrl++ and Ctrl+- to change the font size, it's awesome.
Another solution is to build an associative array with date format and then reformat data.
This method is useful for date formatted in an unussual way.
An example:
mydate='01.02.12 10:20:43':
myformat='dd/mm/yy HH:MM:ss';
dtsplit=mydate.split(/[\/ .:]/);
dfsplit=myformat.split(/[\/ .:]/);
// creates assoc array for date
df = new Array();
for(dc=0;dc<6;dc++) {
df[dfsplit[dc]]=dtsplit[dc];
}
// uses assc array for standard mysql format
dstring[r] = '20'+df['yy']+'-'+df['mm']+'-'+df['dd'];
dstring[r] += ' '+df['HH']+':'+df['MM']+':'+df['ss'];
In Rails 2, I would have written:
validates_uniqueness_of :zipcode, :scope => :recorded_at
In Rails 3:
validates :zipcode, :uniqueness => {:scope => :recorded_at}
For multiple attributes:
validates :zipcode, :uniqueness => {:scope => [:recorded_at, :something_else]}

What is “export default” in JavaScript?
In default export the naming of import is completely independent and we can use any name we like.
I will illustrate this line with a simple example.
Let’s say we have three modules and an index.html file:
export function hello() {
console.log("Modul: Saying hello!");
}
export let variable = 123;
export function hello2() {
console.log("Module2: Saying hello for the second time!");
}
export let variable2 = 456;
modul3.js
export default function hello3() {
console.log("Module3: Saying hello for the third time!");
}
<script type="module">
import * as mod from './modul.js';
import {hello2, variable2} from './modul2.js';
import blabla from './modul3.js'; // ! Here is the important stuff - we name the variable for the module as we like
mod.hello();
console.log("Module: " + mod.variable);
hello2();
console.log("Module2: " + variable2);
blabla();
</script>
The output is:
modul.js:2:10 -> Modul: Saying hello!
index.html:7:9 -> Module: 123
modul2.js:2:10 -> Module2: Saying hello for the second time!
index.html:10:9 -> Module2: 456
modul3.js:2:10 -> Module3: Saying hello for the third time!
So the longer explanation is:
'export default' is used if you want to export a single thing for a module.
So the thing that is important is "import blabla from './modul3.js'" - we could say instead:
"import pamelanderson from './modul3.js" and then pamelanderson();
. This will work just fine when we use 'export default' and basically this is it - it allows us to name it whatever we like when it is default.
P.S.: If you want to test the example - create the files first, and then allow CORS in the browser -> if you are using Firefox type in the URL of the browser: about:config -> Search for "privacy.file_unique_origin" -> change it to "false" -> open index.html -> press F12 to open the console and see the output -> Enjoy and don't forget to return the CORS settings to default.
P.S.2: Sorry for the silly variable naming

401 (Unauthorized) response header -> Request authentication header
Here are several WWW-Authenticate
response headers. (The full list is at IANA: HTTP Authentication Schemes.)
WWW-Authenticate: Basic
-> Authorization: Basic + token - Use for basic authentication WWW-Authenticate: NTLM
-> Authorization: NTLM + token (2 challenges)WWW-Authenticate: Negotiate
-> Authorization: Negotiate + token - used for Kerberos authentication
Negotiate
: This authentication scheme violates both HTTP semantics (being connection-oriented) and syntax (use of syntax incompatible with the WWW-Authenticate and Authorization header field syntax).You can set the Authorization: Basic
header only when you also have the WWW-Authenticate: Basic
header on your 401 challenge.
But since you have WWW-Authenticate: Negotiate
this should be the case for Kerberos based authentication.
You can also get this error if you use special character greek letters like \alpha \beta and so on outside of math mode. After i wrapped them in \(...\) the error was gone.

Yes... The first parameter of the RAISERROR function needs an NVARCHAR variable. So try the following;
-- Replace PRINT function
DECLARE @strMsg NVARCHAR(100)
SELECT @strMsg = 'Here''s your message...'
RAISERROR (@strMsg, 0, 1) WITH NOWAIT
OR
RAISERROR (n'Here''s your message...', 0, 1) WITH NOWAIT
A Jmeter Test Plan must have listener to showcase the result of performance test execution.
Listeners capture the response coming back from Server while Jmeter runs and showcase in the form of – tree, tables, graphs and log files.
It also allows you to save the result in a file for future reference. There are many types of listeners Jmeter provides. Some of them are: Summary Report, Aggregate Report, Aggregate Graph, View Results Tree, View Results in Table etc.
Here is the detailed understanding of each parameter in Summary report.
By referring to the figure:
Label: It is the name/URL for the specific HTTP(s) Request. If you have selected “Include group name in label?” option then the name of the Thread Group is applied as the prefix to each label.
Samples: This indicates the number of virtual users per request.
Average: It is the average time taken by all the samples to execute specific label. In our case, the average time for Label 1 is 942 milliseconds & total average time is 584 milliseconds.
Min: The shortest time taken by a sample for specific label. If we look at Min value for Label 1 then, out of 20 samples shortest response time one of the sample had was 584 milliseconds.
Max: The longest time taken by a sample for specific label. If we look at Max value for Label 1 then, out of 20 samples longest response time one of the sample had was 2867 milliseconds.
Std. Dev.: This shows the set of exceptional cases which were deviating from the average value of sample response time. The lesser this value more consistent the data. Standard deviation should be less than or equal to half of the average time for a label.
Error%: Percentage of Failed requests per Label.
Throughput: Throughput is the number of request that are processed per time unit(seconds, minutes, hours) by the server. This time is calculated from the start of first sample to the end of the last sample. Larger throughput is better.
KB/Sec: This indicates the amount of data downloaded from server during the performance test execution. In short, it is the Throughput measured in Kilobytes per second.

This is now supported (as of 2019). Please see sajad saderi's answer below for instructions.
No, this is not currently supported (in 2015).
Either use readOnly modifier with the constant one needs to declare or one might declare a constant outside the class and use it specifically only in the required class using get operator.
DBCC OPENTRAN helps to identify active transactions that may be preventing log truncation. DBCC OPENTRAN displays information about the oldest active transaction and the oldest distributed and nondistributed replicated transactions, if any, within the transaction log of the specified database. Results are displayed only if there is an active transaction that exists in the log or if the database contains replication information.
An informational message is displayed if there are no active transactions in the log.
For me, it was a missing app domain. Go into the app, and make sure that you have the root of your site set up as an app domain. See screenshot.
I have tried all suggestions and found my own simple solution.
The problem is that codes written in external environment like C
need compiler. Look for its own VS environment, i.e. VS 2008.
Currently my machine runs VS 2012 and faces Unable to find vcvarsall.bat
.
I studied codes that i want to install to find the VS version. It was VS 2008. i have add to system variable VS90COMNTOOLS
as variable name and gave the value of VS120COMNTOOLS
.
You can find my step by step solution below:
Now open a new session and pip install your-package
Here ya go:
viewNoteDateMonth.text = [[displayDate objectAtIndex:2] uppercaseString];
Btw:
"april"
is lowercase
? [NSString lowercaseString]
"APRIL"
is UPPERCASE
? [NSString uppercaseString]
"April May"
is Capitalized/Word Caps
? [NSString capitalizedString]
"April may"
is Sentence caps
? (method missing; see workaround below)
Hence what you want is called "uppercase", not "capitalized". ;)
As for "Sentence Caps" one has to keep in mind that usually "Sentence" means "entire string". If you wish for real sentences use the second method, below, otherwise the first:
@interface NSString ()
- (NSString *)sentenceCapitalizedString; // sentence == entire string
- (NSString *)realSentenceCapitalizedString; // sentence == real sentences
@end
@implementation NSString
- (NSString *)sentenceCapitalizedString {
if (![self length]) {
return [NSString string];
}
NSString *uppercase = [[self substringToIndex:1] uppercaseString];
NSString *lowercase = [[self substringFromIndex:1] lowercaseString];
return [uppercase stringByAppendingString:lowercase];
}
- (NSString *)realSentenceCapitalizedString {
__block NSMutableString *mutableSelf = [NSMutableString stringWithString:self];
[self enumerateSubstringsInRange:NSMakeRange(0, [self length])
options:NSStringEnumerationBySentences
usingBlock:^(NSString *sentence, NSRange sentenceRange, NSRange enclosingRange, BOOL *stop) {
[mutableSelf replaceCharactersInRange:sentenceRange withString:[sentence sentenceCapitalizedString]];
}];
return [NSString stringWithString:mutableSelf]; // or just return mutableSelf.
}
@end
One of the benefits is that Razor views can be rendered inside unit tests, this is something that was not easily possible with the previous ASP.Net renderer.
From ScottGu's announcement this is listed as one of the design goals:
Unit Testable: The new view engine implementation will support the ability to unit test views (without requiring a controller or web-server, and can be hosted in any unit test project – no special app-domain required).
http://momentjs.com/docs/#/displaying/unix-timestamp/
You get the number of unix seconds, not milliseconds!
You you need to multiply it with 1000 or using valueOf()
and don't forget to use a formatter, since you are using a non ISO 8601 format. And if you forget to pass the formatter, the date will be parsed in the UTC timezone or as an invalid date.
moment("10/15/2014 9:00", "MM/DD/YYYY HH:mm").valueOf()
If you're using Spring Boot, the simplest way to disable the Spring Security default headers is to use security.headers.*
properties. In particular, if you want to disable the X-Frame-Options
default header, just add the following to your application.properties
:
security.headers.frame=false
There is also security.headers.cache
, security.headers.content-type
, security.headers.hsts
and security.headers.xss
properties that you can use. For more information, take a look at SecurityProperties
.
I think the main complaints about sqlite scaling is:
You can use this to check the exception and the inner exception for a Win32Exception derived exception.
catch (Exception e) {
var w32ex = e as Win32Exception;
if(w32ex == null) {
w32ex = e.InnerException as Win32Exception;
}
if(w32ex != null) {
int code = w32ex.ErrorCode;
// do stuff
}
// do other stuff
}
Starting with C# 6, when can be used in a catch statement to specify a condition that must be true for the handler for a specific exception to execute.
catch (Win32Exception ex) when (ex.InnerException is Win32Exception) {
var w32ex = (Win32Exception)ex.InnerException;
var code = w32ex.ErrorCode;
}
As in the comments, you really need to see what exception is actually being thrown to understand what you can do, and in which case a specific catch is preferred over just catching Exception. Something like:
catch (BlahBlahException ex) {
// do stuff
}
Also System.Exception has a HRESULT
catch (Exception ex) {
var code = ex.HResult;
}
However, it's only available from .NET 4.5 upwards.
This can help without rounding
declare @test float(25)
declare @test1 decimal(10,5)
select @test = 34.0387597207
select @test
set @test1 = convert (decimal(10,5), @test)
select cast((@test1) as varchar(12))
Select LEFT(cast((@test1) as varchar(12)),LEN(cast((@test1) as varchar(12)))-1)
I was in a process of switching from one version control service to another and needed to clone all repositories including all branches, tags and history.
To achieve above I did next:
git push origin '*:*'
.sh script used to checkout all branches to local repository:
for branch in `git branch -a | grep remotes | grep -v HEAD | grep -v master `; do
git branch --track ${branch#remotes/origin/} $branch
done
Remove all br
tags and use display: table
.
.text span {
background: rgba(165, 220, 79, 0.8);
display: table;
padding: 7px 10px;
color: white;
}
.fullscreen .large { font-size: 80px }
Explanation: The table wraps the width of its content by default without setting a width, but is still a block level element. You can get the same behavior by setting a width to other block-level elements:
<span style="display:block;border:1px solid red;width:100px;">Like a default table.</span>
<code>null</code>
Notice the <code>
element doesn't flow inline with the <span>
like it would normally. Check it out with the computed styles in your dev tools. You'll see pseudo margin to the right of the <span>
. Anyway, this is the same as the table, but the table has the added benefit of always forming to the width of its content.
In my case the bitmap image file already existed in the system drive, so my app threw the error "A Generic error occured in GDI+".
Within a constructor, you can use the this
keyword to invoke another constructor in the same class. Doing so is called an explicit constructor invocation.
Here's another Rectangle class, with a different implementation from the one in the Objects section.
public class Rectangle {
private int x, y;
private int width, height;
public Rectangle() {
this(1, 1);
}
public Rectangle(int width, int height) {
this( 0,0,width, height);
}
public Rectangle(int x, int y, int width, int height) {
this.x = x;
this.y = y;
this.width = width;
this.height = height;
}
}
This class contains a set of constructors. Each constructor initializes some or all of the rectangle's member variables.
According to the packages list in Ubuntu Wily Xenial Bionic there is a package named openjfx. This should be a candidate for what you're looking for:
JavaFX/OpenJFX 8 - Rich client application platform for Java
You can install it via:
sudo apt-get install openjfx
It provides the following JAR files to the OpenJDK installation on Ubuntu systems:
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/jfxswt.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/ant-javafx.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/javafx-mx.jar
If you want to have sources available, for example for debugging, you can additionally install:
sudo apt-get install openjfx-source
While looking at the same problem, I found an example
<style type="text/css">
#topright {
position: absolute;
right: 0;
top: 0;
display: block;
height: 125px;
width: 125px;
background: url(TRbanner.gif) no-repeat;
text-indent: -999em;
text-decoration: none;
}
</style>
<a id="topright" href="#" title="TopRight">Top Right Link Text</a>
The trick here is to create a small, (I used GIMP) a PNG (or GIF) that has a transparent background, (and then just delete the opposite bottom corner.)
try these two line from terminal
sudo killall mysqld
sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start
Assign each div a class
. Then you can perform actions on all of them:
$(".divClass").hide();
So each button can do:
$(".divClass").hide()
$("#specificDiv").show();
You can make this more generic, and use the obvious convention - the button and the div with the same number in the id are related. So:
$(".button").click(function() {
var divId = "#div" + $(this).attr("id").replace("showdiv", "");
$(".divClass").hide();
$(divId).show();
}
It works fine oracle
merge into table1 t1
using (select * from table2) t2
on (t1.empid = t2.empid)
when matched then update set t1.salary = t2.salary
gethostname()
is POSIX way to get local host name. Check out man
.
BSD function getdomainname()
can give you domain name so you can build fully qualified hostname. There is no POSIX way to get a domain I'm afraid.
You can try/catch PDOException
s (your configs could differ but the important part is the try/catch):
try {
$dbh = new PDO(
DB_TYPE . ':host=' . DB_HOST . ';dbname=' . DB_NAME . ';charset=' . DB_CHARSET,
DB_USER,
DB_PASS,
[
PDO::ATTR_PERSISTENT => true,
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES ' . DB_CHARSET . ' COLLATE ' . DB_COLLATE
]
);
} catch ( PDOException $e ) {
echo 'ERROR!';
print_r( $e );
}
The print_r( $e );
line will show you everything you need, for example I had a recent case where the error message was like unknown database 'my_db'
.
"location" directive should be inside a 'server' directive, e.g.
server {
listen 8765;
location / {
resolver 8.8.8.8;
proxy_pass http://$http_host$uri$is_args$args;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
ProgressDialog has become deprecated since API Level 26 https://developer.android.com/reference/android/app/ProgressDialog.html
I include a ProgressBar in my layout
<ProgressBar
android:layout_weight="1"
android:id="@+id/progressBar_cyclic"
android:visibility="gone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minHeight="40dp"
android:minWidth="40dp" />
and change its visibility to .GONE | .VISIBLE depending on the use case.
progressBar_cyclic.visibility = View.VISIBLE
EDIT: Probably not the right way to do it, see comments
You could use sklearn.feature_selection.f_regression.
If you use the gson.JsonObject you can have something like that:
import com.google.gson.JsonObject;
import com.google.gson.JsonParser;
String jsonString = "{'test1':'value1','test2':{'id':0,'name':'testName'}}"
JsonObject jsonObject = (JsonObject) jsonParser.parse(jsonString)
Given a first selector: SelectorA, you can find the next match of SelectorB as below:
Example with mouseover to change border-with:
$("SelectorA").on("mouseover", function() {
var i = $(this).find("SelectorB")[0];
$(i).css({"border" : "1px"});
});
}
General use example to change border-with:
var i = $("SelectorA").find("SelectorB")[0];
$(i).css({"border" : "1px"});
Also, what helped me understand this particular scenario that you described is the Promise API documentation, specifically where it explains how the promised returned by the then
method will be resolved differently depending on what the handler fn returns:
if the handler function:
- returns a value, the promise returned by then gets resolved with the returned value as its value;
- throws an error, the promise returned by then gets rejected with the thrown error as its value;
- returns an already resolved promise, the promise returned by then gets resolved with that promise's value as its value;
- returns an already rejected promise, the promise returned by then gets rejected with that promise's value as its value.
- returns another pending promise object, the resolution/rejection of the promise returned by then will be subsequent to the resolution/rejection of the promise returned by the handler. Also, the value of the promise returned by then will be the same as the value of the promise returned by the handler.
If you open a command prompt and type the following two commands, all framework versions that are installed on the current machine will be listed (each one is stored in a separate directory within this directory).
cd %systemroot%\Microsoft.NET\Framework

Many built-in operations like sum
and prod
are already able to operate across rows or columns, so you may be able to refactor the function you are applying to take advantage of this.
If that's not a viable option, one way to do it is to collect the rows or columns into cells using mat2cell
or num2cell
, then use cellfun
to operate on the resulting cell array.
As an example, let's say you want to sum the columns of a matrix M
. You can do this simply using sum
:
M = magic(10); %# A 10-by-10 matrix
columnSums = sum(M, 1); %# A 1-by-10 vector of sums for each column
And here is how you would do this using the more complicated num2cell
/cellfun
option:
M = magic(10); %# A 10-by-10 matrix
C = num2cell(M, 1); %# Collect the columns into cells
columnSums = cellfun(@sum, C); %# A 1-by-10 vector of sums for each cell
What you're basically doing here is relying on Date#toString()
which already has a fixed pattern. To convert a Java Date
object into another human readable String pattern, you need SimpleDateFormat#format()
.
private String modifyDateLayout(String inputDate) throws ParseException{
Date date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss z").parse(inputDate);
return new SimpleDateFormat("dd.MM.yyyy HH:mm:ss").format(date);
}
By the way, the "unparseable date" exception can here only be thrown by SimpleDateFormat#parse()
. This means that the inputDate
isn't in the expected pattern "yyyy-MM-dd HH:mm:ss z"
. You'll probably need to modify the pattern to match the inputDate
's actual pattern.
Update: Okay, I did a test:
public static void main(String[] args) throws Exception {
String inputDate = "2010-01-04 01:32:27 UTC";
String newDate = new Test().modifyDateLayout(inputDate);
System.out.println(newDate);
}
This correctly prints:
03.01.2010 21:32:27
(I'm on GMT-4)
Update 2: as per your edit, you really got a ParseException
on that. The most suspicious part would then be the timezone of UTC
. Is this actually known at your Java environment? What Java version and what OS version are you using? Check TimeZone.getAvailableIDs()
. There must be a UTC
in between.
The path is in the registry but usually you edit through this interface:
Control Panel
-> System
-> System settings
-> Environment Variables
.PATH
.c:\path;c:\path2
var newTH = document.createElement('th');
newTH.innerHTML = 'Hello, World!';
newTH.onclick = function () {
this.parentElement.removeChild(this);
};
var table = document.getElementById('content');
table.appendChild(newTH);
Working example: http://jsfiddle.net/23tBM/
You can also just hide with this.style.display = 'none'
.
Using dataset with default values is one way, but you must use query for Available values and for Default Values, if values are hard coded in Available values tab, then you must define default values as expressions. Pictures should explain everything
Create Parameter (if not automaticly created)
Define values - wrong way example
Define values - correct way example
Set default values - you must define all default values reflecting available values to make "Select All" by default, if you won't define all only those defined will be selected by default.
The Result
One picture for Data type: Int
There are two solutions posted on that page. The one with lower votes I would recommend if possible.
If you are using HTML5 then it is perfectly valid to put a div
inside of a
. As long as the div doesn't also contain some other specific elements like other link tags.
<a href="Music.html">
<div id="music" class="nav">
Music I Like
</div>
</a>
The solution you are confused about actually makes the link as big as its container div. To make it work in your example you just need to add position: relative
to your div. You also have a small syntax error which is that you have given the span a class instead of an id. You also need to put your span inside the link because that is what the user is clicking on. I don't think you need the z-index
at all from that example.
div { position: relative; }
.hyperspan {
position:absolute;
width:100%;
height:100%;
left:0;
top:0;
}
<div id="music" class="nav">Music I Like
<a href="http://www.google.com">
<span class="hyperspan"></span>
</a>
</div>
When you give absolute
positioning to an element it bases its location and size after the first parent it finds that is relatively positioned. If none, then it uses the document. By adding relative
to the parent div you tell the span to only be as big as that.

you have to place this fomula in cell B1 so it will get the value of your formula
I think this should work:

function getJsonDetails() {
item = {}
item ["token1"] = token1val;
item ["token2"] = token1val;
return item;
}
console.log(JSON.stringify(getJsonDetails()))
this output ll print as (a valid json)

You can create new User library,

and create your library and (add Jars buttons) include your specific Jars.
I hope this can help you.
Your thread's locale is set to one in which the decimal mark is "," instead of ".".
Try using this:
float.Parse("41.00027357629127", CultureInfo.InvariantCulture.NumberFormat);
Note, however, that a float cannot hold that many digits of precision. You would have to use double or Decimal to do so.

If your team uses descriptive commit messages (eg. "Ticket #12345 - Update dependencies") on this project, then generating changelog since the latest tag can de done like this:
git log --no-merges --pretty=format:"%s" 'old-tag^'...new-tag > /path/to/changelog.md
--no-merges
omits the merge commits from the listold-tag^
refers to the previous commit earlier than the tagged one. Useful if you want to see the tagged commit at the bottom of the list by any reason. (Single quotes needed only for iTerm on mac OS).Should be pretty straightforward, its just the reverse of your previous method;
public static int GetEnumFromDescription(string description, Type enumType)
{
foreach (var field in enumType.GetFields())
{
DescriptionAttribute attribute
= Attribute.GetCustomAttribute(field, typeof(DescriptionAttribute))as DescriptionAttribute;
if(attribute == null)
continue;
if(attribute.Description == description)
{
return (int) field.GetValue(null);
}
}
return 0;
}
Usage:
Console.WriteLine((Animal)GetEnumFromDescription("Giant Panda",typeof(Animal)));
If this div is a function I suggest use cursor:pointer in your style like style="cursor:pointer" and can use onclick function.

I have tried every method mentioned above and nothing worked, except installing jupyter in the new environment.
to activate the new environment
conda activate new_env
replace 'new_env' with your environment name.
next install jupyter 'pip install jupyter'
you can also install jupyter by going to anaconda navigator and selecting the right environment, and installing jupyter notebook from Home tab

You are correct, this is indeed a way to initialize member variables. I'm not sure that there's much benefit to this, other than clearly expressing that it's an initialization. Having a "bar=num" inside the code could get moved around, deleted, or misinterpreted much more easily.
Don't forget that in .htaccess files it is a relative URL that is matched.

You have mentioned column name as "NAME" only.
But in STUDENT table ,column name is lets say "NMAE"
The problem obviously was (as you figured it out) that port 36250 wasn't open on the server side at the time you tried to connect (hence connection refused). I can see the server was supposed to open this socket after receiving SEND
command on another connection, but it apparently was "not opening [it] up in sync with the client side".
Well, the main reason would be there was no synchronisation whatsoever. Calling:
cs.send("SEND " + FILE)
cs.close()
would just place the data into a OS buffer; close
would probably flush the data and push into the network, but it would almost certainly return before the data would reach the server. Adding sleep
after close
might mitigate the problem, but this is not synchronisation.
The correct solution would be to make sure the server has opened the connection. This would require server sending you some message back (for example OK
, or better PORT 36250
to indicate where to connect). This would make sure the server is already listening.
The other thing is you must check the return values of send
to make sure how many bytes was taken from your buffer. Or use sendall
.
(Sorry for disturbing with this late answer, but I found this to be a high traffic question and I really didn't like the sleep idea in the comments section.)
Very useful I had a slightly different scenario where I the request xml was itself the body of the POST and not a param. For that the following code can be used - Posting as an answer just in case anyone else having similar issue will benefit.
final HttpHeaders headers = new HttpHeaders();
headers.add("header1", "9998");
headers.add("username", "xxxxx");
headers.add("password", "xxxxx");
headers.add("header2", "yyyyyy");
headers.add("header3", "zzzzz");
headers.setContentType(MediaType.APPLICATION_XML);
headers.setAccept(Arrays.asList(MediaType.APPLICATION_XML));
final HttpEntity<MyXmlbeansRequestDocument> httpEntity = new HttpEntity<MyXmlbeansRequestDocument>(
MyXmlbeansRequestDocument.Factory.parse(request), headers);
final ResponseEntity<MyXmlbeansResponseDocument> responseEntity = restTemplate.exchange(url, HttpMethod.POST, httpEntity,MyXmlbeansResponseDocument.class);
log.info(responseEntity.getBody());
Yes, you can target both x86 and x64 with the same code base in the same project. In general, things will Just Work if you create the right solution configurations in VS.NET (although P/Invoke to entirely unmanaged DLLs will most likely require some conditional code): the items that I found to require special attention are:
The assembly reference issue can't be solved entirely within VS.NET, as it will only allow you to add a reference with a given name to a project once. To work around this, edit your project file manually (in VS, right-click your project file in the Solution Explorer, select Unload Project, then right-click again and select Edit). After adding a reference to, say, the x86 version of an assembly, your project file will contain something like:
<Reference Include="Filename, ..., processorArchitecture=x86">
<HintPath>C:\path\to\x86\DLL</HintPath>
</Reference>
Wrap that Reference tag inside an ItemGroup tag indicating the solution configuration it applies to, e.g:
<ItemGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x86' ">
<Reference ...>....</Reference>
</ItemGroup>
Then, copy and paste the entire ItemGroup tag, and edit it to contain the details of your 64-bit DLL, e.g.:
<ItemGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x64' ">
<Reference Include="Filename, ..., processorArchitecture=AMD64">
<HintPath>C:\path\to\x64\DLL</HintPath>
</Reference>
</ItemGroup>
After reloading your project in VS.NET, the Assembly Reference dialog will be a bit confused by these changes, and you may encounter some warnings about assemblies with the wrong target processor, but all your builds will work just fine.
Solving the MSI issue is up next, and unfortunately this will require a non-VS.NET tool: I prefer Caphyon's Advanced Installer for that purpose, as it pulls off the basic trick involved (create a common MSI, as well as 32-bit and 64-bit specific MSIs, and use an .EXE setup launcher to extract the right version and do the required fixups at runtime) very, very well.
You can probably achieve the same results using other tools or the Windows Installer XML (WiX) toolset, but Advanced Installer makes things so easy (and is quite affordable at that) that I've never really looked at alternatives.
One thing you may still require WiX for though, even when using Advanced Installer, is for your .NET Installer Class custom actions. Although it's trivial to specify certain actions that should only run on certain platforms (using the VersionNT64 and NOT VersionNT64 execution conditions, respectively), the built-in AI custom actions will be executed using the 32-bit Framework, even on 64-bit machines.
This may be fixed in a future release, but for now (or when using a different tool to create your MSIs that has the same issue), you can use WiX 3.0's managed custom action support to create action DLLs with the proper bitness that will be executed using the corresponding Framework.
Edit: as of version 8.1.2, Advanced Installer correctly supports 64-bit custom actions. Since my original answer, its price has increased quite a bit, unfortunately, even though it's still extremely good value when compared to InstallShield and its ilk...
Edit: If your DLLs are registered in the GAC, you can also use the standard reference tags this way (SQLite as an example):
<ItemGroup Condition="'$(Platform)' == 'x86'">
<Reference Include="System.Data.SQLite, Version=1.0.80.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139, processorArchitecture=x86" />
</ItemGroup>
<ItemGroup Condition="'$(Platform)' == 'x64'">
<Reference Include="System.Data.SQLite, Version=1.0.80.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139, processorArchitecture=AMD64" />
</ItemGroup>
The condition is also reduced down to all build types, release or debug, and just specifies the processor architecture.
All credit to Rajeev Kumar's answer, but I received a list of anonymous type that evaluated to string, which was not as easy to iterate over. Updating the code as below helped to return a List that was more easy to manipulate (or, for example, drop straight into a foreach block).
var distinctIds = datatable.AsEnumerable().Select(row => row.Field<string>("id")).Distinct().ToList();
If you will use pre defined delete methods as directly provided by spring JPA then below two queries will be execute by the framework.
First collect data(like id and other column) using by execute select query with delete query where clause.
then after getting resultSet of first query, second delete queries will be execute for all id(one by one)
Note : This is not optimized way for your application because many queries will be execute for single MYSQL delete query.
This is another optimized way for delete query code because only one delete query will execute by using below customized methods.
@NamedNativeQueries({
@NamedNativeQuery(name = "Abc.deleteByCreatedTimeBetween",
query = "DELETE FROM abc WHERE create_time BETWEEN ?1 AND ?2")
,
@NamedNativeQuery(name = "Abc.getByMaxId",
query = "SELECT max(id) from abc")
})
@Entity
public class Abc implements Serializable {
}
@Repository
public interface AbcRepository extends CrudRepository {
int getByMaxId();
@Transactional
@Modifying
void deleteByCreatedTimeBetween(String startDate, String endDate);
}
Try to use union all
as below
SELECT [Type], [Total Sales] From Before
union all
SELECT 'Total', Sum([Total Sales]) From Before
if you have problem with ordering, as i-one suggested try this:
select [Type], [Total Sales]
from (SELECT [Type], [Total Sales], 0 [Key]
From Before
union all
SELECT 'Total', Sum([Total Sales]), 1 From Before) sq
order by [Key], Type
My original answer was written in 2009. While it still works, I'd like to update it for 2017. Browsers can still behave differently. I trust the jQuery team to do a great job at maintaining cross-browser consistency. However, it's not necessary to include the entire library. In the jQuery source, the relevant portion is found on line 37 of dimensions.js. Here it is extracted and modified to work standalone:
function getWidth() {_x000D_
return Math.max(_x000D_
document.body.scrollWidth,_x000D_
document.documentElement.scrollWidth,_x000D_
document.body.offsetWidth,_x000D_
document.documentElement.offsetWidth,_x000D_
document.documentElement.clientWidth_x000D_
);_x000D_
}_x000D_
_x000D_
function getHeight() {_x000D_
return Math.max(_x000D_
document.body.scrollHeight,_x000D_
document.documentElement.scrollHeight,_x000D_
document.body.offsetHeight,_x000D_
document.documentElement.offsetHeight,_x000D_
document.documentElement.clientHeight_x000D_
);_x000D_
}_x000D_
_x000D_
console.log('Width: ' + getWidth() );_x000D_
console.log('Height: ' + getHeight() );
_x000D_
Since all browsers behave differently, you'll need to test for values first, and then use the correct one. Here's a function that does this for you:
function getWidth() {
if (self.innerWidth) {
return self.innerWidth;
}
if (document.documentElement && document.documentElement.clientWidth) {
return document.documentElement.clientWidth;
}
if (document.body) {
return document.body.clientWidth;
}
}
and similarly for height:
function getHeight() {
if (self.innerHeight) {
return self.innerHeight;
}
if (document.documentElement && document.documentElement.clientHeight) {
return document.documentElement.clientHeight;
}
if (document.body) {
return document.body.clientHeight;
}
}
Call both of these in your scripts using getWidth()
or getHeight()
. If none of the browser's native properties are defined, it will return undefined
.
This may not work for all images, but some images contain a root user already, such as in the jupyterhub/singleuser image. With that image it's simply:
USER root
RUN sudo apt-get update
If someone is looking for the simplest way without collections
module. I guess this will be helpful:
>>> s = "asldaksldkalskdla"
>>> {i:s.count(i) for i in set(s)}
{'a': 4, 'd': 3, 'k': 3, 's': 3, 'l': 4}
or
>>> [(i,s.count(i)) for i in set(s)]
[('a', 4), ('k', 3), ('s', 3), ('l', 4), ('d', 3)]
check your project build in jdk 9 or not above that eclipse is having some issues with the modules. Change it to jdk 9 then it will run fine
Here's a batch file, called base64encode.bat, that encodes base64.
@echo off
if not "%1" == "" goto :arg1exists
echo usage: base64encode input-file [output-file]
goto :eof
:arg1exists
set base64out=%2
if "%base64out%" == "" set base64out=con
(
set base64tmp=base64.tmp
certutil -encode "%1" %base64tmp% > nul
findstr /v /c:- %base64tmp%
erase %base64tmp%
) > %base64out%
You need
str.CopyTo(data);
data.Position = 0; // reset to beginning
byte[] buf = new byte[data.Length];
data.Read(buf, 0, buf.Length);
And since your Test()
method is imitating the client it ought to Close()
or Dispose()
the str
Stream. And the memoryStream too, just out of principal.
Here's a nice, tidy solution for you: (also see the live demo ->)
window.onload = function start() {
slide();
}
function slide() {
var currMarg = 0,
contStyle = document.getElementById('container').style;
setInterval(function() {
currMarg = currMarg == 1800 ? 0 : currMarg + 600;
contStyle.marginLeft = '-' + currMarg + 'px';
}, 3000);
}
Since you are trying to learn, allow me to explain how this works.
First we declare two variables: currMarg
and contStyle
. currMarg
is an integer that we will use to track/update what left margin the container should have. We declare it outside the actual update function (in a closure), so that it can be continuously updated/access without losing its value. contStyle
is simply a convenience variable that gives us access to the containers styles without having to locate the element on each interval.
Next, we will use setInterval
to establish a function which should be called every 3 seconds, until we tell it to stop (there's your infinite loop, without freezing the browser). It works exactly like setTimeout
, except it happens infinitely until cancelled, instead of just happening once.
We pass an anonymous function to setInterval
, which will do our work for us. The first line is:
currMarg = currMarg == 1800 ? 0 : currMarg + 600;
This is a ternary operator. It will assign currMarg
the value of 0
if currMarg
is equal to 1800
, otherwise it will increment currMarg
by 600
.
With the second line, we simply assign our chosen value to container
s marginLeft, and we're done!
Note: For the demo, I changed the negative values to positive, so the effect would be visible.
I happened to be in a particular situation where my usecase resembled the one of Mureinik but I ended-up using the solution of Tomasz Nurkiewicz.
Here is how:
class TestedClass extends AARRGGHH {
public LoginContext login(String user, String password) {
LoginContext lc = new LoginContext("login", callbackHandler);
lc.doThis();
lc.doThat();
return lc;
}
}
Now, PowerMockRunner
failed to initialize TestedClass
because it extends AARRGGHH
, which in turn does more contextual initialization... You see where this path was leading me: I would have needed to mock on several layers. Clearly a HUGE smell.
I found a nice hack with minimal refactoring of TestedClass
: I created a small method
LoginContext initLoginContext(String login, CallbackHandler callbackHandler) {
new lc = new LoginContext(login, callbackHandler);
}
The scope of this method is necessarily package
.
Then your test stub will look like:
LoginContext lcMock = mock(LoginContext.class)
TestedClass testClass = spy(new TestedClass(withAllNeededArgs))
doReturn(lcMock)
.when(testClass)
.initLoginContext("login", callbackHandler)
and the trick is done...
Under Linux, What worked for me was John Anderson's (sontek) guide, which you can find at this link. However, I cheated and just used his easy configuration setup from his Git repostiory:
git clone -b vim https://github.com/sontek/dotfiles.git
cd dotfiles
./install.sh vim
His configuration is fairly up to date as of today.
Radio buttons have another attribute - checked or unchecked. You need to set which button was selected by the user, so you have to write PHP code inside the HTML with these values - checked or unchecked. Here's one way to do it:
The PHP code:
<?PHP
$male_status = 'unchecked';
$female_status = 'unchecked';
if (isset($_POST['Submit1'])) {
$selected_radio = $_POST['gender'];
if ($selected_radio == 'male') {
$male_status = 'checked';
}else if ($selected_radio == 'female') {
$female_status = 'checked';
}
}
?>
The HTML FORM code:
<FORM name ="form1" method ="post" action ="radioButton.php">
<Input type = 'Radio' Name ='gender' value= 'male'
<?PHP print $male_status; ?>
>Male
<Input type = 'Radio' Name ='gender' value= 'female'
<?PHP print $female_status; ?>
>Female
<P>
<Input type = "Submit" Name = "Submit1" VALUE = "Select a Radio Button">
</FORM>

Your example is not reproducible since there is no ex1221new
(there is an ex1221
in Sleuth2
, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot
. One advantage is that ggplot
works with data.frame
s directly.
You can set the labels with xlab()
and ylab()
, or make it part of the scale_*.*
call.
library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area() +
xlab("My x label") +
ylab("My y label") +
ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area("Nitrogen") +
scale_x_continuous("My x label") +
scale_y_continuous("My y label") +
ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs
function
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area() +
labs(size= "Nitrogen",
x = "My x label",
y = "My y label",
title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
which gives an identical figure to the one above.
If you have a numpy array, you can do the following:
>>> import numpy as np
>>> a = np.array([133, 53, 234, 241])
>>> a.astype(np.uint8).data.hex()
'8535eaf1'
I know this is a year old, but I just discovered this works perfectly for an EditText.
EditText textin = (EditText) findViewById(R.id.editText1);
textin.setInputType(InputType.TYPE_CLASS_TEXT);
It prevents anything but text and space. I could not tab, "return" ("\n"), or anything.

document.addEventListener('DOMContentLoaded', fn);
} else {
document.attachEvent('onreadystatechange', function() {

Since the OP is just development/testing, less than sleek solutions may be helpful:
setcap can be used on a script's interpreter to grant capabilities to scripts. If setcaps on the global interpreter binary is not acceptable, make a local copy of the binary (any user can) and get root to setcap on this copy. Python2 (at least) works properly with a local copy of the interpreter in your script development tree. No suid is needed so the root user can control to what capabilities users have access.
If you need to track system-wide updates to the interpreter, use a shell script like the following to run your script:
#!/bin/sh
#
# Watch for updates to the Python2 interpreter
PRG=python_net_raw
PRG_ORIG=/usr/bin/python2.7
cmp $PRG_ORIG $PRG || {
echo ""
echo "***** $PRG_ORIG has been updated *****"
echo "Run the following commands to refresh $PRG:"
echo ""
echo " $ cp $PRG_ORIG $PRG"
echo " # setcap cap_net_raw+ep $PRG"
echo ""
exit
}
./$PRG $*

You don't need to install Entity Framework in your Console application, you just need to add a reference to the assembly EntityFramework.SqlServer.dll. You can copy this assembly from the Class Library project that uses Entity Framework to a LIB folder and add a reference to it.
In summary:
I hope it helps.
