Try using dos2unix to strip off the ^M.
In my case, I needed to add the JMETER_HOME environment variable to be available via my Ant build scripts across all projects on my Jenkins server (Linux), in a way that would not interfere with my local build environment (Windows and Mac) in the build.xml script. Setting the environment variable via Manage Jenkins - Configure System - Global properties was the easiest and least intrusive way to accomplish this. No plug-ins are necessary.
The environment variable is then available in Ant via:
<property environment="env" />
<property name="jmeter.home" value="${env.JMETER_HOME}" />
This can be verified to works by adding:
<echo message="JMeter Home: ${jmeter.home}"/>
Which produces:
JMeter Home: ~/.jmeter
You should use textView.setGravity(Gravity.CENTER_HORIZONTAL);.
Remember that using
LinearLayout.LayoutParams layoutParams =new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
layoutParams2.gravity = Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL;
won't work. This will set the gravity for the widget and not for it's text.
There is a solution actually, by applying the "anonymous class" trick and the ideas from the Super Type Tokens:
public final class Voodoo {
public static void chill(final List<?> aListWithSomeType) {
// Here I'd like to get the Class-Object 'SpiderMan'
System.out.println(aListWithSomeType.getClass().getGenericSuperclass());
System.out.println(((ParameterizedType) aListWithSomeType
.getClass()
.getGenericSuperclass()).getActualTypeArguments()[0]);
}
public static void main(String... args) {
chill(new ArrayList<SpiderMan>() {});
}
}
class SpiderMan {
}
The trick lies in the creation of an anonymous class, new ArrayList<SpiderMan>() {}, in the place of the original (simple) new ArrayList<SpiderMan>(). The use of an anoymous class (if possible) ensures that the compiler retains information about the type argument SpiderMan given to the type parameter List<?>. Voilà !
You could simply use:
select {
border: none;
outline: none;
scroll-behavior: smooth;
}
As the drop down list border is non editable you can not do anything with that but surely this will fix your initial outlook.
Just go to Control Panel > Programs and Features, and they all appear listed there.
I'm no expert and this answer is pretty simple compared to what people are answering (checking registry), so I'm not sure if it's the correct answer but it did the trick for me.
In my case i had to load images on radio button click,
I just uses the regular onclick event and it worked for me.
<input type="radio" name="colors" value="{{color.id}}" id="{{color.id}}-option" class="color_radion" onclick="return get_images(this, {{color.id}})">
<script>
function get_images(obj, color){
console.log($("input[type='radio'][name='colors']:checked").val());
}
</script>

Recall that in Dijkstra's algorithm, once a vertex is marked as "closed" (and out of the open set) -it assumes that any node originating from it will lead to greater distance so, the algorithm found the shortest path to it, and will never have to develop this node again, but this doesn't hold true in case of negative weights.

Comment as an answer:

This works because any variable in JS can be evaluated as a boolean, so this will generally catch things that are empty, null, or undefined.

Here is an adaptation for Luda's answer for Swift:
In the declaration of your UIViewController subclass put
let numberToolbar: UIToolbar = UIToolbar()
in ViewDidLoad put:
numberToolbar.barStyle = UIBarStyle.BlackTranslucent
numberToolbar.items=[
UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.Bordered, target: self, action: "hoopla"),
UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: self, action: nil),
UIBarButtonItem(title: "Apply", style: UIBarButtonItemStyle.Bordered, target: self, action: "boopla")
]
numberToolbar.sizeToFit()
textField.inputAccessoryView = numberToolbar //do it for every relevant textfield if there are more than one
and the add the functions hoopla and hoopla (feel free to choose other names, just change the selector names in ViewDidLoad accordingly
func boopla () {
textField.resignFirstResponder()
}
func hoopla () {
textField.text=""
textField.resignFirstResponder()
}
$('.checkbox').attr('checked',true);
will not work with from jQuery 1.6.
Instead use
$('.checkbox').prop('checked',true);
$('.checkbox').prop('checked',false);
Full explanation / examples and demo can be found in the jQuery API Documentation https://api.jquery.com/attr/
{{ path(app.request.attributes.get('_route'),
app.request.attributes.get('_route_params')) }}
If you want to read it into a view variable:
{% set currentPath = path(app.request.attributes.get('_route'),
app.request.attributes.get('_route_params')) %}
The app global view variable contains all sorts of useful shortcuts, such as app.session and app.security.token.user, that reference the services you might use in a controller.

The JDK provides
Collections.unmodifiableXXXmethods, but in our opinion, these can be unwieldy and verbose; unpleasant to use everywhere you want to make defensive copies unsafe: the returned collections are only truly immutable if nobody holds a reference to the original collection inefficient: the data structures still have all the overhead of mutable collections, including concurrent modification checks, extra space in hash tables, etc.

git commit --no-verify
-n
--no-verify
This option bypasses the pre-commit and commit-msg hooks. See also githooks(5).
As commented by Blaise, -n can have a different role for certain commands.
For instance, git push -n is actually a dry-run push.
Only git push --no-verify would skip the hook.
Note: Git 2.14.x/2.15 improves the --no-verify behavior:
See commit 680ee55 (14 Aug 2017) by Kevin Willford (``).
(Merged by Junio C Hamano -- gitster -- in commit c3e034f, 23 Aug 2017)
commit: skip discarding the index if there is nopre-commithook"
git commit" used to discard the index and re-read from the filesystem just in case thepre-commithook has updated it in the middle; this has been optimized out when we know we do not run thepre-commithook.
Davi Lima points out in the comments the git cherry-pick does not support --no-verify.
So if a cherry-pick triggers a pre-commit hook, you might, as in this blog post, have to comment/disable somehow that hook in order for your git cherry-pick to proceed.
The same process would be necessary in case of a git rebase --continue, after a merge conflict resolution.
Add your test.js file after the jQuery libraries. This way your test.js file can use the libraries.
@parag's code works great. But while loading some large images you may fail. You should use;
imageView.setImageBitmap(getScaledBitmap(picturePath, 800, 800));
instead of;
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
Here are my methods that you can use.
private Bitmap getScaledBitmap(String picturePath, int width, int height) {
BitmapFactory.Options sizeOptions = new BitmapFactory.Options();
sizeOptions.inJustDecodeBounds = true;
BitmapFactory.decodeFile(picturePath, sizeOptions);
int inSampleSize = calculateInSampleSize(sizeOptions, width, height);
sizeOptions.inJustDecodeBounds = false;
sizeOptions.inSampleSize = inSampleSize;
return BitmapFactory.decodeFile(picturePath, sizeOptions);
}
private int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
// Calculate ratios of height and width to requested height and
// width
final int heightRatio = Math.round((float) height / (float) reqHeight);
final int widthRatio = Math.round((float) width / (float) reqWidth);
// Choose the smallest ratio as inSampleSize value, this will
// guarantee
// a final image with both dimensions larger than or equal to the
// requested height and width.
inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
}
return inSampleSize;

Here is my subroutine approach to this problem. it transforms an integer in the range 0 : 9999 as a character. For example, the INTEGER 123 is transformed into the character 0123. hope it helps.
P.S. - sorry for the comments; they make sense in Romanian :P

implicit none
integer :: i
integer :: integer_zeci,rest_zeci,integer_sute,rest_sute,integer_mii,rest_mii
character(1) :: filename1,filename2,filename3,filename4
character(4) :: filename_tot
! Subrutina ce transforma un INTEGER de la 0 la 9999 in o serie de CARACTERE cu acelasi numar
! pentru a fi folosite in numerotarea si denumirea fisierelor de rezultate.
if(i<=9) then
filename1=char(48+0)
filename2=char(48+0)
filename3=char(48+0)
filename4=char(48+i)
elseif(i>=10.and.i<=99) then

Interface is the class that contains an abstract method that cannot create any object.Since Interface cannot create the object and its not a pure class, Its no worth implementing it.
When you read() the file, you may get a newline character '\n' in your string. Try either
if UserInput.strip() == 'List contents': or
if 'List contents' in UserInput: Also note that your second file open could also use with:
with open('/Users/.../USER_INPUT.txt', 'w+') as UserInputFile: if UserInput.strip() == 'List contents': # or if s in f: UserInputFile.write("ls") else: print "Didn't work" You can achieve this without an ID using the a[name]:not([href]) css selector. This simply looks for links with a name and no href e.g. <a name="anc1"></a>
An example rule might be:
a[name]:not([href]){
display: block;
position: relative;
top: -100px;
visibility: hidden;
}
declareThere is no need on using prefixes like on other answers, neither arrays. Use just declare, double quotes, and parameter expansion.
I often use the following trick to parse argument lists contanining one to n arguments formatted as key=value otherkey=othervalue etc=etc, Like:
# brace expansion just to exemplify
for variable in {one=foo,two=bar,ninja=tip}
do
declare "${variable%=*}=${variable#*=}"
done
echo $one $two $ninja
# foo bar tip
But expanding the argv list like
for v in "$@"; do declare "${v%=*}=${v#*=}"; done
# parse argv's leading key=value parameters
for v in "$@"; do
case "$v" in ?*=?*) declare "${v%=*}=${v#*=}";; *) break;; esac
done
# consume argv's leading key=value parameters
while (( $# )); do
case "$v" in ?*=?*) declare "${v%=*}=${v#*=}";; *) break;; esac
shift
done
This is the more powerful grouping / rollup syntax you'll want to use in SQL Server 2008+. Always useful to specify the version you're using so we don't have to guess.
SELECT
[Type] = COALESCE([Type], 'Total'),
[Total Sales] = SUM([Total Sales])
FROM dbo.Before
GROUP BY GROUPING SETS(([Type]),());
Craig Freedman wrote a great blog post introducing GROUPING SETS.
Please take a look at this example here. It is a simple example of a count up! Which I think you could easily modify to create a count down.

function AlbumCtrl($scope,$timeout) {
$scope.counter = 0;
$scope.onTimeout = function(){
$scope.counter++;
mytimeout = $timeout($scope.onTimeout,1000);
}
var mytimeout = $timeout($scope.onTimeout,1000);
$scope.stop = function(){
$timeout.cancel(mytimeout);
}

You can create a custom encoder that returns a list when it encounters a set. Here's an example:
>>> import json
>>> class SetEncoder(json.JSONEncoder):
... def default(self, obj):
... if isinstance(obj, set):
... return list(obj)
... return json.JSONEncoder.default(self, obj)
...
>>> json.dumps(set([1,2,3,4,5]), cls=SetEncoder)
'[1, 2, 3, 4, 5]'
You can detect other types this way too. If you need to retain that the list was actually a set, you could use a custom encoding. Something like return {'type':'set', 'list':list(obj)} might work.
To illustrated nested types, consider serializing this:
>>> class Something(object):
... pass
>>> json.dumps(set([1,2,3,4,5,Something()]), cls=SetEncoder)
This raises the following error:
TypeError: <__main__.Something object at 0x1691c50> is not JSON serializable
This indicates that the encoder will take the list result returned and recursively call the serializer on its children. To add a custom serializer for multiple types, you can do this:
>>> class SetEncoder(json.JSONEncoder):
... def default(self, obj):
... if isinstance(obj, set):
... return list(obj)
... if isinstance(obj, Something):
... return 'CustomSomethingRepresentation'
... return json.JSONEncoder.default(self, obj)
...
>>> json.dumps(set([1,2,3,4,5,Something()]), cls=SetEncoder)
'[1, 2, 3, 4, 5, "CustomSomethingRepresentation"]'
You need to modify your function as:
function toggleTable()
{
if (document.getElementById("loginTable").style.display == "table" ) {
document.getElementById("loginTable").style.display="none";
} else {
document.getElementById("loginTable").style.display="table";
}
currently it is checking based on the boolean parameter, you don't have to pass the parameter with your function.
You need to modify your anchor tag as:
<a id="loginLink" onclick="toggleTable();" href="#">Login</a>
Have you tried:
(column LIKE '%this%' and something=else) or (column LIKE '%that%' and something=else)
As many people have mentioned before, XML Schema utilize an XML-based syntax and DTDs have a unique syntax. DTD doesn't support datatypes, which does matter.
Lets see a very simple example in which university has multiple students and each student has two elements "name" and "year". Please note that I have uses "// --> " in my code just for comments.
Now I will write this example both in DTD and in XSD.
DTD
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE university[ // --> university as root element
<!ELEMENT university (student*)> // --> university has * = Multiple students
<!ELEMENT student (name,year)> // --> Student has elements name and year
<!ELEMENT name (#PCDATA)> // --> name as Parsed character data
<!ELEMENT year (#PCDATA)> // --> year as Parsed character data
]>
<university>
<student>
<name>
John Niel //---> I can also use an Integer,not good
</name>
<year>
2000 //---> I can also use a string,not good
</year>
</student>
</university>

Calling addView is the correct answer, but you need to do a little more than that to get it to work.
If you create a View via a constructor (e.g., Button myButton = new Button();), you'll need to call setLayoutParams on the newly constructed view, passing in an instance of the parent view's LayoutParams inner class, before you add your newly constructed child to the parent view.
For example, you might have the following code in your onCreate() function assuming your LinearLayout has id R.id.main:
LinearLayout myLayout = findViewById(R.id.main);
Button myButton = new Button(this);
myButton.setLayoutParams(new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT));
myLayout.addView(myButton);
Making sure to set the LayoutParams is important. Every view needs at least a layout_width and a layout_height parameter. Also getting the right inner class is important. I struggled with getting Views added to a TableRow to display properly until I figured out that I wasn't passing an instance of TableRow.LayoutParams to the child view's setLayoutParams.
try
<button onclick="window.location.href='b.php'">Click me</button>
Anuglar import paths are case sensitive.Check if your service paths are correct everywhere you use service and also check the letter cases to be correct and identical everywhere.
private boolean checkDateLimit() {
long CurrentDateInMilisecond = System.currentTimeMillis(); // Date 1
long Date1InMilisecond = Date1.getTimeInMillis(); //Date2
if (CurrentDateInMilisecond <= Date1InMilisecond) {
return true;
} else {
return false;
}
}
// Convert both date into milisecond value .
What sort of button, neither a Forms Control nor an ActiveX control should affect the used range.
It is a known problem that excel does not keep track of the used range very well. Any reference to the used range via VBA will reset the value to the current used range. So try running this sub procedure:
Sub ResetUsedRng()
Application.ActiveSheet.UsedRange
End Sub
Failing that you may well have some formatting hanging round. Try clearing/deleting all the cells after your last row.
Regarding the above also see:
Another method to find the last used cell:
Dim rLastCell As Range
Set rLastCell = ActiveSheet.Cells.Find(What:="*", After:=.Cells(1, 1), LookIn:=xlFormulas, LookAt:= _
xlPart, SearchOrder:=xlByRows, SearchDirection:=xlPrevious, MatchCase:=False)
Change the search direction to find the first used cell.
Use ?? instead or {{ $usersType ?? '' }}
For input number in range 0..100
int n1 = 75; // input value
String res; int n=0;
int[] a ={0,20,35,55,70,85,101};
for(; n1>=a[n]; n++);
switch(6-n+1) {
case 1: res="A"; break;
case 2: res="B"; break;
case 3: res="C"; break;
case 4: res="D"; break;
case 5: res="E"; break;
default:res="F";
}
System.out.println(res);

See part 6. HTTP Authentication
HTTP Authentication
HTTP Authentication is the ability to tell the server your username and password so that it can verify that you're allowed to do the request you're doing. The Basic authentication used in HTTP (which is the type curl uses by default) is plain text based, which means it sends username and password only slightly obfuscated, but still fully readable by anyone that sniffs on the network between you and the remote server.
To tell curl to use a user and password for authentication:
curl --user name:password http://www.example.comThe site might require a different authentication method (check the headers returned by the server), and then --ntlm, --digest, --negotiate or even --anyauth might be options that suit you.
Sometimes your HTTP access is only available through the use of a HTTP proxy. This seems to be especially common at various companies. A HTTP proxy may require its own user and password to allow the client to get through to the Internet. To specify those with curl, run something like:
curl --proxy-user proxyuser:proxypassword curl.haxx.seIf your proxy requires the authentication to be done using the NTLM method, use --proxy-ntlm, if it requires Digest use --proxy-digest.
If you use any one these user+password options but leave out the password part, curl will prompt for the password interactively.
Do note that when a program is run, its parameters might be possible to see when listing the running processes of the system. Thus, other users may be able to watch your passwords if you pass them as plain command line options. There are ways to circumvent this.
It is worth noting that while this is how HTTP Authentication works, very many web sites will not use this concept when they provide logins etc. See the Web Login chapter further below for more details on that.
I would suggest you using my method to get a resource ID. It's Much more efficient, than using getIdentidier() method, which is slow.
Here's the code:
/**
* @author Lonkly
* @param variableName - name of drawable, e.g R.drawable.<b>image</b>
* @param ? - class of resource, e.g R.drawable.class or R.raw.class
* @return integer id of resource
*/
public static int getResId(String variableName, Class<?> ?) {
Field field = null;
int resId = 0;
try {
field = ?.getField(variableName);
try {
resId = field.getInt(null);
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
return resId;
}
If the "archive" table is meant to be an exact copy of you main table then I would just suggest that you remove the fact that the id is an identiy column. That way it will let you insert them.
Alternatively you can allow and the disallow identity inserts for the table with the following statement
SET IDENTITY_INSERT tbl_A_archive ON
--Your inserts here
SET IDENTITY_INSERT tbl_A_archive OFF
Finally, if you need the identity column to work as is then you can always just run the stored proc.
sp_columns tbl_A_archive
This will return you all of the columns from the table which you can then cut and paste into your query. (This is almost ALWAYS better than using a *)

You might want to replace <br/> and </p> tags with newlines before stripping the HTML to prevent it becoming an illegible mess as Tim suggests.
The only way I can think of removing HTML tags but leaving non-HTML between angle brackets would be check against a list of HTML tags. Something along these lines...
replaceAll("\\<[\s]*tag[^>]*>","")
Then HTML-decode special characters such as &. The result should not be considered to be sanitized.
Please do notice that all platform requirements are taken from the name of the *.whl file!
So be very careful with renaming of *.whl package. I occasionally renamed my newly compiled tensorflow package from
tensorflow-1.11.0-cp36-cp36m-linux_x86_64.whl
to
tensorflow-1.11.0-cp36-cp36m-linux_x86_64_gpu.whl
just to remind myself about gpu support and struggled with
tensorflow-1.11.0-cp36-cp36m-linux_x86_64_gpu.whl is not a supported wheel on this platform.

# Adding empty header as parameters are being sent in payload
headers = {}
r = requests.post(url, data=json.dumps(payload), headers=headers)
print(r.content)
You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start(). The headers will be sent automatically when any HTML is output.
Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.
Move the session_start() to the top of your document :
<?php session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php'; // more PHP code here. you can use node-stack-trace module which is a power full module to track call stacks.
not mysqldump, but mysql cli...
mysql -e "select * from myTable" -u myuser -pxxxxxxxxx mydatabase
you can redirect it out to a file if you want :
mysql -e "select * from myTable" -u myuser -pxxxxxxxx mydatabase > mydumpfile.txt
Update: Original post asked if he could dump from the database by query. What he asked and what he meant were different. He really wanted to just mysqldump all tables.
mysqldump --tables myTable --where="id < 1000"
I was having serious problems with
.data('property', value);
It was not setting the data-property attribute.
Started using jQuery's .attr():
Get the value of an attribute for the first element in the set of matched elements or set one or more attributes for every matched element.
.attr('property', value)
to set the value and
.attr('property')
to retrieve the value.
Now it just works!
The answer to my comment above on the Original Question makes me think this is all he wants:
loopnum = 0
word = 'afrykanerskojezyczny'
wordlist = ['afrykanerskojezycznym','afrykanerskojezyczni','nieafrykanerskojezyczni']
for i in wordlist:
wordlist[loopnum] = word
loopnum += 1
This will do the following:
For every value in wordlist, set that value of the wordlist to the origional code.
All you have to do is put this piece of code where you need to change wordlist, making sure you store the words you need to change in wordlist, and that the original word is correct.
Hope this helps!
Konrad Rudolph has the right answer.
If it really bugs you, monkey patch the String class or add it to a class/module of your choice. It's really not a good practice to monkey patch core objects unless you have a really compelling reason though.
class String
def self.nilorempty?(string)
string.nil? || string.empty?
end
end
Then you can do String.nilorempty? mystring

<input type="button" id="uploadProductImages" value="Upload">
Jquery:
$('#callUploadImages').click(function(){
$('#uploadImages').click();
});
$('#uploadImages').change(function(){
var uploadImages = $(this);
$('#uploadImagesInfo').val(uploadImages[0].files.length+" file(s).");

For those of us who have a github.com account, but only get a nasty error message when we type "git" into the command-line, here's how to do it all in your browser :)
Dictionary class is not optimized for this case, but if you really wanted to do it (in C# 2.0), you can do:
public List<TKey> GetKeysFromValue<TKey, TVal>(Dictionary<TKey, TVal> dict, TVal val)
{
List<TKey> ks = new List<TKey>();
foreach(TKey k in dict.Keys)
{
if (dict[k] == val) { ks.Add(k); }
}
return ks;
}
I prefer the LINQ solution for elegance, but this is the 2.0 way.
export PATH=/usr/pgsql-9.2/bin:$PATH
The program executable psql is in the directory /usr/pgsql-9.2/bin, and that directory is not included in the path by default, so we have to tell our shell (terminal) program where to find psql. When most packages are installed, they are added to an existing path, such as /usr/local/bin, but not this program.
So we have to add the program's path to the shell PATH variable if we do not want to have to type the complete path to the program every time we execute it.
This line should typically be added to theshell startup script, which for the bash shell will be in the file ~/.bashrc.
You should always avoid using List<T> as a parameter. Not only because this pattern reduces the opportunities of the caller to store the data in a different kind of collection, but also the caller has to convert the data into a List first.
Converting an IEnumerable into a List costs O(n) complexity which is absolutely unneccessary. And it also creates a new object.
TL;DR you should always use a proper interface like IEnumerable or IQueryable based on what do you want to do with your collection. ;)
In your case:
public void foo(IEnumerable<DateTime> dateTimes)
{
}
this.props.history.push(`/customers/${customer.id}`, null);
If your real and imaginary parts are the slices along the last dimension and your array is contiguous along the last dimension, you can just do
A.view(dtype=np.complex128)
If you are using single precision floats, this would be
A.view(dtype=np.complex64)
Here is a fuller example
import numpy as np
from numpy.random import rand
# Randomly choose real and imaginary parts.
# Treat last axis as the real and imaginary parts.
A = rand(100, 2)
# Cast the array as a complex array
# Note that this will now be a 100x1 array
A_comp = A.view(dtype=np.complex128)
# To get the original array A back from the complex version
A = A.view(dtype=np.float64)
If you want to get rid of the extra dimension that stays around from the casting, you could do something like
A_comp = A.view(dtype=np.complex128)[...,0]
This works because, in memory, a complex number is really just two floating point numbers. The first represents the real part, and the second represents the imaginary part. The view method of the array changes the dtype of the array to reflect that you want to treat two adjacent floating point values as a single complex number and updates the dimension accordingly.
This method does not copy any values in the array or perform any new computations, all it does is create a new array object that views the same block of memory differently. That makes it so that this operation can be performed much faster than anything that involves copying values. It also means that any changes made in the complex-valued array will be reflected in the array with the real and imaginary parts.
It may also be a little trickier to recover the original array if you remove the extra axis that is there immediately after the type cast.
Things like A_comp[...,np.newaxis].view(np.float64) do not currently work because, as of this writing, NumPy doesn't detect that the array is still C-contiguous when the new axis is added.
See this issue.
A_comp.view(np.float64).reshape(A.shape) seems to work in most cases though.
If the project has compilation issue then tests might not run. So firstly build project as Build -> Build Project. After successful compilation re-run the test.
If nothing works out then just close the project window and delete project and re-import as Gradle/Maven project which will set everything for you by overriding the existing IntelliJ created files.This will remove invalid cache created.
You can also just invalidate the cache.
File -> Invalidate Caches/Restart

I wanted to expand upon Daniel Brockman's excellent comment.
Defining git config --global alias.exec '!exec ' allows you to do things like git exec make because, as man git-config states:
If the alias expansion is prefixed with an exclamation point, it will be treated as a shell command. [...] Note that shell commands will be executed from the top-level directory of a repository, which may not necessarily be the current directory.
It's also handy to know that $GIT_PREFIX will be the path to the current directory relative to the top-level directory of a repository. But, knowing it is only half the battle™. Shell variable expansion makes it rather hard to use. So I suggest using bash -c like so:
git exec bash -c 'ls -l $GIT_PREFIX'
other commands include:
git exec pwd
git exec make

If you really want it to show in UTF-8 instead of US ASCII then you need to do it in two steps.
First:
iconv -f us-ascii -t utf-16 yourfile > youfileinutf16.*
Second:
iconv -f utf-16le -t utf-8 yourfileinutf16 > yourfileinutf8.*
Then if you do a file -i, you'll see the new character set is UTF-8.

With gawk, you can use the match function to capture parenthesized groups.
gawk 'match($0, pattern, ary) {print ary[1]}'
example:
echo "abcdef" | gawk 'match($0, /b(.*)e/, a) {print a[1]}'
outputs cd.
Note the specific use of gawk which implements the feature in question.
For a portable alternative you can achieve similar results with match() and substr.
example:
echo "abcdef" | awk 'match($0, /b[^e]*/) {print substr($0, RSTART+1, RLENGTH-1)}'
outputs cd.

decode poly function is to decode the points(lat and long) provided by Directions API in encoded form
None of the solutions worked for me. I noticed that the problem was only occuring in one xaml file, and not in other xaml or c# files.
I had an extension called QuickConverter that allows to create custom bindings with in-line converters. This was messing up with Intellisense and this was not detected as an error while building or running the app.
My advice is:
Instead of configuring Tomcat to redirect requests, use Apache as a frontend with the Apache Tomcat connector so that Apache is only serving static content, while asking tomcat for dynamic content.
Using the JKmount directive (or others) you could specify exactly which requests are sent to Tomcat.
Requests for static content, such as images, would be served directly by Apache, using a standard virtual host configuration, while other requests, defined in the JKMount directive will be sent to Tomcat workers.
I think this implementation would give you the most flexibility and control on the overall application.
This worked for me.
def parse_data():
if request.method == "POST":
data = request.get_json()
print(data['answers'])
return render_template('output.html', data=data)
$.ajax({
type: 'POST',
url: "/parse_data",
data: JSON.stringify({values}),
contentType: "application/json;charset=utf-8",
dataType: "json",
success: function(data){
// do something with the received data
}
});
There are a number of different ways to do this. You might want to check out XStream or JAXB. There are tutorials and the examples.
If you are not satisfied with lists (because they can contain anything and take up too much memory) you can use efficient array of integers:
import array
array.array('i')
See here
If you need to initialize it,
a = array.array('i',(0 for i in range(0,10)))
simply add the following attribute
// for disabled i.e. cannot highlight value or change
disabled="disabled"
// for readonly i.e. can highlight value but not change
readonly="readonly"
jQuery to make the change to the element (substitute disabled for readonly in the following for setting readonly attribute).
$('#fieldName').attr("disabled","disabled")
or
$('#fieldName').attr("disabled", true)
NOTE: As of jQuery 1.6, it is recommended to use .prop() instead of .attr(). The above code will work exactly the same except substitute .attr() for .prop().
Using Google Collections, assuming K is your key type:
Maps.filterKeys(treeMap, new Predicate<K>() {
@Override
public boolean apply(K key) {
return false; //return true here if you need the entry to be in your new map
}});
You can use filterEntries instead if you need the value as well.
You can check like this
public void checktype() {
ConnectivityManager cm = (ConnectivityManager) this.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if (activeNetwork != null) { // connected to the internet
if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {
// connected to wifi
Toast.makeText(this, activeNetwork.getTypeName(), Toast.LENGTH_SHORT).show();
} else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {
// connected to the mobile provider's data plan
Toast.makeText(this, activeNetwork.getTypeName(), Toast.LENGTH_SHORT).show();
}
}
}
A shorter version of converting List to Array of specific type (for example Long):
Long[] myArray = myList.toArray(Long[]::new);
I use PowerShell to re-launch the script elevated if it's not. Put these lines at the very top of your script.
net file 1>nul 2>nul && goto :run || powershell -ex unrestricted -Command "Start-Process -Verb RunAs -FilePath '%comspec%' -ArgumentList '/c %~fnx0 %*'"
goto :eof
:run
:: TODO: Put code here that needs elevation
I copied the 'net name' method from @Matt's answer. His answer is much better documented and has error messages and the like. This one has the advantage that PowerShell is already installed and available on Windows 7 and up. No temporary VBScript (*.vbs) files, and you don't have to download tools.
This method should work without any configuration or setup, as long as your PowerShell execution permissions aren't locked down.
You forgot to print the result. What you get is the P in RE(P)L and not the actual printed result.
In Py2.x you should so something like
>>> print "\n".join(['I', 'would', 'expect', 'multiple', 'lines'])
I
would
expect
multiple
lines
and in Py3.X, print is a function, so you should do
print("\n".join(['I', 'would', 'expect', 'multiple', 'lines']))
Now that was the short answer. Your Python Interpreter, which is actually a REPL, always displays the representation of the string rather than the actual displayed output. Representation is what you would get with the repr statement
>>> print repr("\n".join(['I', 'would', 'expect', 'multiple', 'lines']))
'I\nwould\nexpect\nmultiple\nlines'
I had the exact same question as you had and I think I should share how I started to understand it by a few really simple examples (note that it only covers the common use cases).
There are two common use cases in Scala using implicit.
Examples are as follows
Using it on a variable. As you can see, if the implicit keyword is used in the last parameter list, then the closest variable will be used.
// Here I define a class and initiated an instance of this class
case class Person(val name: String)
val charles: Person = Person("Charles")
// Here I define a function
def greeting(words: String)(implicit person: Person) = person match {
case Person(name: String) if name != "" => s"$name, $words"
case _ => "$words"
}
greeting("Good morning") // Charles, Good moring
val charles: Person = Person("")
greeting("Good morning") // Good moring
Using it on a function. As you can see, if the implicit is used on the function, then the closest type conversion method will be used.
val num = 10 // num: Int (of course)
// Here I define a implicit function
implicit def intToString(num: Int) = s"$num -- I am a String now!"
val num = 10 // num: Int (of course). Nothing happens yet.. Compiler believes you want 10 to be an Int
// Util...
val num: String = 10 // Compiler trust you first, and it thinks you have `implicitly` told it that you had a way to covert the type from Int to String, which the function `intToString` can do!
// So num is now actually "10 -- I am a String now!"
// console will print this -> val num: String = 10 -- I am a String now!
Hope this can help.
My Answer: All of the following should be overridden (i.e. describe them all within columndefinition, if appropriate):
lengthprecisionscalenullableuniquei.e. the column DDL will consist of: name + columndefinition and nothing else.
Rationale follows.
Annotation containing the word "Column" or "Table" is purely physical - properties only used to control DDL/DML against database.
Other annotation purely logical - properties used in-memory in java to control JPA processing.
That's why sometimes it appears the optionality/nullability is set twice - once via @Basic(...,optional=true) and once via @Column(...,nullable=true). Former says attribute/association can be null in the JPA object model (in-memory), at flush time; latter says DB column can be null. Usually you'd want them set the same - but not always, depending on how the DB tables are setup and reused.
In your example, length and nullable properties are overridden and redundant.
So, when specifying columnDefinition, what other properties of @Column are made redundant?
In JPA Spec & javadoc:
columnDefinition definition:
The SQL fragment that is used when generating the DDL for the column.
columnDefinition default:
Generated SQL to create a column of the inferred type.
The following examples are provided:
@Column(name="DESC", columnDefinition="CLOB NOT NULL", table="EMP_DETAIL")
@Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL")
And, err..., that's it really. :-$ ?!
Does columnDefinition override other properties provided in the same annotation?
The javadoc and JPA spec don't explicity address this - spec's not giving great protection. To be 100% sure, test with your chosen implementation.
The following can be safely implied from examples provided in the JPA spec
name & table can be used in conjunction with columnDefinition, neither are overriddennullable is overridden/made redundant by columnDefinitionThe following can be fairly safely implied from the "logic of the situation" (did I just say that?? :-P ):
length, precision, scale are overridden/made redundant by the columnDefinition - they are integral to the typeinsertable and updateable are provided separately and never included in columnDefinition, because they control SQL generation in-memory, before it is emmitted to the database.That leaves just the "unique" property. It's similar to nullable - extends/qualifies the type definition, so should be treated integral to type definition. i.e. should be overridden.
Test My Answer For columns "A" & "B", respectively:
@Column(name="...", table="...", insertable=true, updateable=false,
columndefinition="NUMBER(5,2) NOT NULL UNIQUE"
@Column(name="...", table="...", insertable=false, updateable=true,
columndefinition="NVARCHAR2(100) NULL"
I found an excellent solution to this problem on Mats Karlsson's blog. The solution is to write a subclass of ActionResult that serializes data via JSON.NET, configuring the latter to follow the camelCase convention:
public class JsonCamelCaseResult : ActionResult
{
public JsonCamelCaseResult(object data, JsonRequestBehavior jsonRequestBehavior)
{
Data = data;
JsonRequestBehavior = jsonRequestBehavior;
}
public Encoding ContentEncoding { get; set; }
public string ContentType { get; set; }
public object Data { get; set; }
public JsonRequestBehavior JsonRequestBehavior { get; set; }
public override void ExecuteResult(ControllerContext context)
{
if (context == null)
{
throw new ArgumentNullException("context");
}

Here's an extended version of Andy E's linked "Handle array-style query strings"-version. Fixed a bug (?key=1&key[]=2&key[]=3; 1 is lost and replaced with [2,3]), made a few minor performance improvements (re-decoding of values, recalculating "[" position, etc.) and added a number of improvements (functionalized, support for ?key=1&key=2, support for ; delimiters). I left the variables annoyingly short, but added comments galore to make them readable (oh, and I reused v within the local functions, sorry if that is confusing ;).
It will handle the following querystring...
?test=Hello&person=neek&person[]=jeff&person[]=jim&person[extra]=john&test3&nocache=1398914891264
...making it into an object that looks like...
{
"test": "Hello",
"person": {
"0": "neek",
"1": "jeff",
"2": "jim",
"length": 3,
"extra": "john"
},
"test3": "",
"nocache": "1398914891264"
}
As you can see above, this version handles some measure of "malformed" arrays, i.e. - person=neek&person[]=jeff&person[]=jim or person=neek&person=jeff&person=jim as the key is identifiable and valid (at least in dotNet's NameValueCollection.Add):
If the specified key already exists in the target NameValueCollection instance, the specified value is added to the existing comma-separated list of values in the form "value1,value2,value3".
It seems the jury is somewhat out on repeated keys as there is no spec. In this case, multiple keys are stored as an (fake)array. But do note that I do not process values based on commas into arrays.
The code:
getQueryStringKey = function(key) {
return getQueryStringAsObject()[key];
};
getQueryStringAsObject = function() {
var b, cv, e, k, ma, sk, v, r = {},
d = function (v) { return decodeURIComponent(v).replace(/\+/g, " "); }, //# d(ecode) the v(alue)
q = window.location.search.substring(1), //# suggested: q = decodeURIComponent(window.location.search.substring(1)),
s = /([^&;=]+)=?([^&;]*)/g //# original regex that does not allow for ; as a delimiter: /([^&=]+)=?([^&]*)/g
;
//# ma(make array) out of the v(alue)
ma = function(v) {
//# If the passed v(alue) hasn't been setup as an object
if (typeof v != "object") {
//# Grab the cv(current value) then setup the v(alue) as an object
cv = v;
v = {};
v.length = 0;
//# If there was a cv(current value), .push it into the new v(alue)'s array
//# NOTE: This may or may not be 100% logical to do... but it's better than loosing the original value
if (cv) { Array.prototype.push.call(v, cv); }
}
return v;
};
//# While we still have key-value e(ntries) from the q(uerystring) via the s(earch regex)...
while (e = s.exec(q)) { //# while((e = s.exec(q)) !== null) {
//# Collect the open b(racket) location (if any) then set the d(ecoded) v(alue) from the above split key-value e(ntry)
b = e[1].indexOf("[");
v = d(e[2]);
//# As long as this is NOT a hash[]-style key-value e(ntry)
if (b < 0) { //# b == "-1"
//# d(ecode) the simple k(ey)
k = d(e[1]);
//# If the k(ey) already exists
if (r[k]) {
//# ma(make array) out of the k(ey) then .push the v(alue) into the k(ey)'s array in the r(eturn value)
r[k] = ma(r[k]);
Array.prototype.push.call(r[k], v);
}
//# Else this is a new k(ey), so just add the k(ey)/v(alue) into the r(eturn value)
else {
r[k] = v;
}
}
//# Else we've got ourselves a hash[]-style key-value e(ntry)
else {
//# Collect the d(ecoded) k(ey) and the d(ecoded) sk(sub-key) based on the b(racket) locations
k = d(e[1].slice(0, b));
sk = d(e[1].slice(b + 1, e[1].indexOf("]", b)));
//# ma(make array) out of the k(ey)
r[k] = ma(r[k]);
//# If we have a sk(sub-key), plug the v(alue) into it
if (sk) { r[k][sk] = v; }
//# Else .push the v(alue) into the k(ey)'s array
else { Array.prototype.push.call(r[k], v); }
}
}
//# Return the r(eturn value)
return r;
};
First off: The variables a and b in the loops refer to numpy.ndarray objects.
In the first loop, a = a + 1 is evaluated as follows: the __add__(self, other) function of numpy.ndarray is called. This creates a new object and hence, A is not modified. Afterwards, the variable a is set to refer to the result.
In the second loop, no new object is created. The statement b += 1 calls the __iadd__(self, other) function of numpy.ndarray which modifies the ndarray object in place to which b is referring to. Hence, B is modified.
Gson gson = new Gson();
JsonParser parser = new JsonParser();
JsonObject object = (JsonObject) parser.parse(response);// response will be the json String
YourPojo emp = gson.fromJson(object, YourPojo.class);
in your action performed method, call:
label1.setText(nameField.getText());
This way, when the button is clicked, label will be updated to the nameField text.
Steps I followed for an overall dark theme including file browser:
Preferences->Theme...Adaptive.sublime-themeI'm taking a course in Android/iPhone development and we spent 8 weeks with Titanium (not full time) (Version was Titanium 1.4.2 and time was around November 2010). Here is my experience.
Even though the API guides claim that the functionality is available for both the Android and iPhone, this is not the case. Much of the stuff simply don't work on one of the platforms. Some things works differently.
A lot of the people in the class has done iPhone applications, and they can not make them work on Android without major rewrites. I developed a simple childrens app called Animap (see android market / Appstore in Sweden) and started developing under Windows. Once the Android target was working I opened the project on OS X. It does not show any build stuff for iPhone, just for Android. You need to start a dual target project under OS X. (Ok, I copied the relevant files to a new project). Next problem - the animations does not work on iPhone (they work on Android). The scrolling events does not work the same on the iPhone. (i.e on Android you get the untouch event when user stops scrolling and releases their finger from the screen, this does not happen on the iPhone).
Since this is not mentioned somewhere you basicly need to do trial and error programming on first one platform, then on the other platform. By trial and error I mean it will take about two days to get such a simple App as Animap working on the other platform. You will also need to have if (android) then... or if(iphone)... all over your code...
You must follow the instructions to the letter. Do not try to use java 64 bit. It will not compile the KitchenSink 1.4.0 demo application. (1.3 works OK!) You must put files directly on the C drive as long pathnames will make the external program not receiving all command line parameters if they get to long. (Fine for small programs though) 1/3 of the times, the toolchain simply stops and you must press 'launch' again. Then it will probably work... very unreliable. The simulator will not be found on startup and then you must simply kill of adb.exe with Ctrl+Alt+Delete and retry.
On a wifi-network you sometimes looses the live connection and Titanium crashes on you (the compile/deploy interface) If you do not have a working internet connection it will not start as it can not log you in to their servers.
CSS, HTML and jQuery is a breeze compared to this. Titanium resembles any other old GUI API, and you need to set some properties for every single button/field/etc. Getting a field wrong is just to easy, remembering all the properties that needs to be set? Did you spell it with capital letters at the right place? (as this is not caught by the compiler, but will be seen as a runtime error if you are lucky to test that part)
In Titanium things simply break when you add another view on top of a control or click somewhere else in the GUI.
Several API pages carry the Android symbol, but will only return a null when you try to create the control. They are not simply available on the Android platform despite the symbols. Sometimes Android is mention to not support a particular method, but then the whole API is missing.
The demo application. Did I mention it does not compile if you put it in your Eclipse project folder because the path gets too long? Must be put on your C drive in the root folder. I currently use a symbolik link (mklink /J ...)
You must propably use things as label.setText('Hello World') to change a label reliable but this is not documented at all.
Titanium.API.info('Printouts are the only way to debug');
The APIs are not available in any good format so you can not get ordinary code-completion with help etc. in Eclipse. Aptana please help out!
It seems that the compiler/tools are not multithreaded so a fast computer with a fast harddrive is a must, as you must do a lot of trial & error. Did I mention the poor documentation? You must try out everything there as you can't trust it!
From previous projects I have promised myself never ever to use closed source again as you can't simply fix things just by throwing hours and manpower at it. Important when you are late in the project and need to deliver for a hard deadline. This is open source and I have been able to see why the tool chain breaks and actually fix it as well.
Bugdatabase
It's also open. You can simply see that your not alone and do a workaround instead of another 4 hours spent on trial&error.
Community
Much of the problems I have had with Titanium comes from my background on realtime systems like OSE who support hundreds of threads, events and message passing. This is supposed to work in Titanium 1.4 but it simply doesn't do it reliably.
Javascript (which is new to me) dies silently on runtime errors. This also means that small and common bugs, like misspelling a variable name or reading in a null-pointer does not crash when it should so you can debug it. Instead parts of your program just stop working, for instance an eventhandler, because you misplaced/misstyped a character.
Then we have more simple bugs in Titanium, like some parameters not working in the functions (which is quite common on the Android platform at least).
Trial and Error debug cycle speed Having run Titnium Developer on several computers, I noticed that the bottleneck is the harddrive. An SSD drive on a laptop makes the build cycle about 3-5 times faster than on a 4200 rpm drive. On a desktop, having dual drives in RAID 1 (striping mode) makes the build about 25 percent faster than on a single drive with a somewhat faster CPU and it also beats the SSD drive laptop.
This shines through very much when you start using it. If you look at the open bugtracker you see that the number of bugs keeps increasing faster than the number of fixed bugs. This is usually a sign that the developers keep adding more functionality, rather than concentrating on getting the number of bugs down.
As a consultant trying to deliver rather simple apps to multiplatforms for a customer - I'm not sure this is actually faster than doing native app development on two platforms. This is due to the fact that when you are up to speed you are fast with Titanium, but then suddenly you look down and find yourself in a hole so deep you don't know how many hours must be spent for a workaround. You can simply NOT promise a certain functionality for a certain deadline/time/cost.
About myself: Been using Python for two years with wxPython. (that GUI is inconsitent, but never breaks like this. It might be me that have not understood the threading model used by Javascript and Titanium, but I am not alone according to their open discussion forums, GUI objects are suddenly using the wrong context/not updating..???) before that I have a background in C and ASM programming for mobile devices.
[edit - added part with bugs and not being thread safe] [Edit - now having worked with it for a month+, mostly on PC but some on OS X as well. Added iPhone and Android dual targetting. Added Trial and Error debug cycle speed.]
App-Prefs:root=Privacy&path=LOCATION worked for me for getting to general location settings. Note: only works on a device.
Stopping (Killing) a thread mid-way is not recommended. The API is actually deprecated.
However,you can get more details including workarounds here: How do you kill a thread in Java?
Simply restarting Visual Studio worked for me.
You're passing link=$a and link=$b in the hrefs for A and B, respectively. They are treated as strings, not variables. The following should fix that for you:
echo '<a href="pass.php?link=' . $a . '">Link 1</a>';
// and
echo '<a href="pass.php?link=' . $b . '">Link 2</a>';
The value of $a also isn't included on pass.php. I would suggest making a common variable file and include it on all necessary pages.
Here too I can reproduce this problem with scrapy and psycopg2 (both require C++ compiling), even though I have Microsoft Visual C++ Compiler for Python 2.7 installed.
It has to be noted that I use virtualenv. From your post I'm not sure whether you do the same.
Anyway I tried to skip the activation of the virtual environment. Then both scrapy and psycopg2 installed fine.
My hypothesis: there is a conflict between this 2014 C++ compiler for Python and virtualenv. I do not know why nor how to solve it (and I'd be glad if someone can suggest a workaround).
Try this:
public class Team
{
public int TeamId { get; set;}
public string Name { get; set; }
public virtual ICollection<Match> HomeMatches { get; set; }
public virtual ICollection<Match> AwayMatches { get; set; }
}
public class Match
{
public int MatchId { get; set; }
public int HomeTeamId { get; set; }
public int GuestTeamId { get; set; }
public float HomePoints { get; set; }
public float GuestPoints { get; set; }
public DateTime Date { get; set; }
public virtual Team HomeTeam { get; set; }
public virtual Team GuestTeam { get; set; }
}
public class Context : DbContext
{
...
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<Match>()
.HasRequired(m => m.HomeTeam)
.WithMany(t => t.HomeMatches)
.HasForeignKey(m => m.HomeTeamId)
.WillCascadeOnDelete(false);
modelBuilder.Entity<Match>()
.HasRequired(m => m.GuestTeam)
.WithMany(t => t.AwayMatches)
.HasForeignKey(m => m.GuestTeamId)
.WillCascadeOnDelete(false);
}
}
Primary keys are mapped by default convention. Team must have two collection of matches. You can't have single collection referenced by two FKs. Match is mapped without cascading delete because it doesn't work in these self referencing many-to-many.
This downloaded the entire website for me:
wget --no-clobber --convert-links --random-wait -r -p -E -e robots=off -U mozilla http://site/path/
It is better to demonstrate this way
if [[ $# -eq 0 ]] ; then
echo 'some message'
exit 1
fi
You normally need to exit if you have too few arguments.
You can try this
$('.myDiv').bind('DOMNodeInserted DOMNodeRemoved', function() {
});
but this might not work in internet explorer, haven't tested it
I use node-fetch because it uses the familiar (if you are a web developer) fetch() API. fetch() is the new way to make arbitrary HTTP requests from the browser.
Yes I know this is a node js question, but don't we want to reduce the number of API's developers have to memorize and understand, and improve re-useability of our javascript code? Fetch is a standard so how about we converge on that?
The other nice thing about fetch() is that it returns a javascript Promise, so you can write async code like this:
let fetch = require('node-fetch');
fetch('http://localhost', {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body: '{}'
}).then(response => {
return response.json();
}).catch(err => {console.log(err);});
Fetch supersedes XMLHTTPRequest. Here's some more info.
I would like to give you also the idea to disable an <option> with a given defined value (not innerhtml). I recommend to it with jQuery to get the simplest way. See my sample below.
HTML
Status:
<div id="option">
<select class="status">
<option value="hand" selected>Hand</option>
<option value="simple">Typed</option>
<option value="printed">Printed</option>
</select>
</div>
Javascript
The idea here is how to disable Printed option when current Status is Hand
var status = $('#option').find('.status');//to get current the selected value
var op = status.find('option');//to get the elements for disable attribute
(status.val() == 'hand')? op[2].disabled = true: op[2].disabled = false;
You may see how it works here:
Use stringr::str_split_fixed
library(stringr)
str_split_fixed(before$type, "_and_", 2)
Just keep
Intent intent = new Intent(ProfileActivity.this,
LoginActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
See https://polarssl.org/kb/cryptography/asn1-key-structures-in-der-and-pem (search the page for "BEGIN RSA PRIVATE KEY") (archive link for posterity, just in case).
BEGIN RSA PRIVATE KEY is PKCS#1 and is just an RSA key. It is essentially just the key object from PKCS#8, but without the version or algorithm identifier in front. BEGIN PRIVATE KEY is PKCS#8 and indicates that the key type is included in the key data itself. From the link:
The unencrypted PKCS#8 encoded data starts and ends with the tags:
-----BEGIN PRIVATE KEY----- BASE64 ENCODED DATA -----END PRIVATE KEY-----Within the base64 encoded data the following DER structure is present:
PrivateKeyInfo ::= SEQUENCE { version Version, algorithm AlgorithmIdentifier, PrivateKey BIT STRING } AlgorithmIdentifier ::= SEQUENCE { algorithm OBJECT IDENTIFIER, parameters ANY DEFINED BY algorithm OPTIONAL }So for an RSA private key, the OID is 1.2.840.113549.1.1.1 and there is a RSAPrivateKey as the PrivateKey key data bitstring.
As opposed to BEGIN RSA PRIVATE KEY, which always specifies an RSA key and therefore doesn't include a key type OID. BEGIN RSA PRIVATE KEY is PKCS#1:
RSA Private Key file (PKCS#1)
The RSA private key PEM file is specific for RSA keys.
It starts and ends with the tags:
-----BEGIN RSA PRIVATE KEY----- BASE64 ENCODED DATA -----END RSA PRIVATE KEY-----Within the base64 encoded data the following DER structure is present:
RSAPrivateKey ::= SEQUENCE { version Version, modulus INTEGER, -- n publicExponent INTEGER, -- e privateExponent INTEGER, -- d prime1 INTEGER, -- p prime2 INTEGER, -- q exponent1 INTEGER, -- d mod (p-1) exponent2 INTEGER, -- d mod (q-1) coefficient INTEGER, -- (inverse of q) mod p otherPrimeInfos OtherPrimeInfos OPTIONAL }
I am also working with Laravel and I like the implementation there. I tried to mimic it and combining it with the solution proposed by T. Stone (look above):
PRODUCTION_SERVERS = ['*.webfaction.com','*.whatever.com',]
def check_env():
for item in PRODUCTION_SERVERS:
match = re.match(r"(^." + item + "$)", socket.gethostname())
if match:
return True
if check_env():
PRODUCTION = True
else:
PRODUCTION = False
DEBUG = not PRODUCTION
Maybe something like this would help you.
Use substring method like this::
str.substring(str.length()-2);
See what I've done here: http://jsfiddle.net/dyarbrough93/c8wEC/
First off, you never set the dimensions of the overlay, meaning it wasn't showing up in the first place. Secondly, I recommend just changing the z-index of the overlay when you hover over the image. Change the opacity / color of the overlay to suit your needs.
.image { position: relative; width: 200px; height: 200px;}
.image img { max-width: 100%; max-height: 100%; }
.overlay { position: absolute; top: 0; left: 0; background-color: gray; z-index: -10; width: 200px; height: 200px; opacity: 0.5}
.image:hover .overlay { z-index: 10}
Either something like this:
"abc" + str(9)
or
"abs{0}".format(9)
or
"abs%d" % (9,)
While working with Maven got same issue then I put XML file into src/main/java path and it worked.
ApplicationContext context=new ClassPathXmlApplicationContext("spring.xml");
Models must be named and called with the first letter of the model name capitalized and the rest in lowercase.
For example: $this->load->model('Logon_model');
and:
class Logon_model extends CI_Model {
...
But you are correct about the file name.
The MyKey class (@Embeddable) should not have any relationships like @ManyToOne
Add XAttribute in the constructor of the XElement, like
new XElement("Conn", new XAttribute("Server", comboBox1.Text));
You can also add multiple attributes or elements via the constructor
new XElement("Conn", new XAttribute("Server", comboBox1.Text), new XAttribute("Database", combobox2.Text));
or you can use the Add-Method of the XElement to add attributes
XElement element = new XElement("Conn");
XAttribute attribute = new XAttribute("Server", comboBox1.Text);
element.Add(attribute);
For JavaScript use:
document.getElementsByClassName('select-holder')[0].placeholder = "This is my new text";
For jQuery use:
$('.select-holder')[0].placeholder = "This is my new text";
there seems to be about a million reasons this bug happens, but for me (running on ubuntu), it was openvpn running in the background that caused it.
I killed the openvpn service and no more issues.

You will have to submit this data to the server somehow. I'm assuming that you don't want to do a full page reload every time a user clicks a link, so you'll have to user XHR (AJAX). If you are not using jQuery (or some other JS library) you can read this tutorial on how to do the XHR request "by hand".

There is an itertools recipes that does this for general iterables. For convenience, you can > pip install more_itertools and import this third-party library that implements such recipes for you:
Code
import more_itertools as mit
mit.nth([1, 2, 3], 0)
# 1
mit.nth([], 0, 5)
# 5
Detail
Here is the implementation of the nth recipe:
def nth(iterable, n, default=None):
"Returns the nth item or a default value"
return next(itertools.islice(iterable, n, None), default)
Like dict.get(), this tool returns a default for missing indices. It applies to general iterables:
mit.nth((0, 1, 2), 1) # tuple
# 1
mit.nth(range(3), 1) # range generator (py3)
# 1
mit.nth(iter([0, 1, 2]), 1) # list iterator

A simple way to have the absolute path of the initially executed script, in that script and any other script included with include, require, require_once is by using a constant and storing there the current script path at beginning of the main script:
define( 'SCRIPT_ROOT', __FILE__ );
The solution above is suitable when there is a single "main" script that includes every other needed script, as in most web applications.
If that's not the case and there may be several "intital scripts" then to avoid redefinitions and to have the correct path stored inside the constant each script may begin with:
if( ! defined( 'SCRIPT_ROOT' ) ) {
define( 'SCRIPT_ROOT`, __FILE__ );
}
A note about the (currently) accepted answer:
the answer states that the initially executed script path is the first element of the array returned by get_included_files().
This is a clever and simple solution and -at the time of writing- (we're almost at PHP 7.4.0) it does work.
However by looking at the documentation there is no mention that the initially executed script is the first item of the array returned by get_included_files().
We only read
The script originally called is considered an "included file," so it will be listed together with the files referenced by include and family.
At the time of writing the "script originally called" is the first one in the array but -technically- there is no guarantee that this won't change in the future.
A note about realpath(), __FILE__, and __DIR__:
Others have suggested in their answers the use of __FILE__, __DIR__, dirname(__FILE__), realpath(__DIR__)...
dirname(__FILE__) is equal to __DIR__ (introduced in PHP 5.3.0), so just use __DIR__.
Both __FILE__ and __DIR__ are always absolute paths so realpath() is unnecessary.
The error message is giving you most of what you need. This isn't just about the TrustedHosts list; it's saying that in order to use an IP address with the default authentication scheme, you have to ALSO be using HTTPS (which isn't configured by default) and provide explicit credentials. I can tell you're at least not using SSL, because you didn't use the -UseSSL switch.
Note that SSL/HTTPS is not configured by default - that's an extra step you'll have to take. You can't just add -UseSSL.
The default authentication mechanism is Kerberos, and it wants to see real host names as they appear in AD. Not IP addresses, not DNS CNAME nicknames. Some folks will enable Basic authentication, which is less picky - but you should also set up HTTPS since you'd otherwise pass credentials in cleartext. Enable-PSRemoting only sets up HTTP.
Adding names to your hosts file won't work. This isn't an issue of name resolution; it's about how the mutual authentication between computers is carried out.
Additionally, if the two computers involved in this connection aren't in the same AD domain, the default authentication mechanism won't work. Read "help about_remote_troubleshooting" for information on configuring non-domain and cross-domain authentication.
From the docs at http://technet.microsoft.com/en-us/library/dd347642.aspx
HOW TO USE AN IP ADDRESS IN A REMOTE COMMAND
-----------------------------------------------------
ERROR: The WinRM client cannot process the request. If the
authentication scheme is different from Kerberos, or if the client
computer is not joined to a domain, then HTTPS transport must be used
or the destination machine must be added to the TrustedHosts
configuration setting.
The ComputerName parameters of the New-PSSession, Enter-PSSession and
Invoke-Command cmdlets accept an IP address as a valid value. However,
because Kerberos authentication does not support IP addresses, NTLM
authentication is used by default whenever you specify an IP address.
When using NTLM authentication, the following procedure is required
for remoting.
1. Configure the computer for HTTPS transport or add the IP addresses
of the remote computers to the TrustedHosts list on the local
computer.
For instructions, see "How to Add a Computer to the TrustedHosts
List" below.
2. Use the Credential parameter in all remote commands.
This is required even when you are submitting the credentials
of the current user.
If you don't mind using numpy, you can use numpy.random.choice.
For example:
import numpy
items = [["item1", 0.2], ["item2", 0.3], ["item3", 0.45], ["item4", 0.05]
elems = [i[0] for i in items]
probs = [i[1] for i in items]
trials = 1000
results = [0] * len(items)
for i in range(trials):
res = numpy.random.choice(items, p=probs) #This is where the item is selected!
results[items.index(res)] += 1
results = [r / float(trials) for r in results]
print "item\texpected\tactual"
for i in range(len(probs)):
print "%s\t%0.4f\t%0.4f" % (items[i], probs[i], results[i])
If you know how many selections you need to make in advance, you can do it without a loop like this:
numpy.random.choice(items, trials, p=probs)
In Windows, with GetFileInformationByHandleEx, passing FileNameInfo, you can retrieve the file name.
if you want smooth scrolling add behavior configuration.
document.getElementById('id').scrollIntoView({
behavior: 'smooth'
});
Put the following code before int main():
using namespace std;
And you will be able to use cout.
For example:
#include<iostream>
using namespace std;
int main(){
char t = 'f';
char *t1;
char **t2;
cout<<t;
return 0;
}
Now take a moment and read up on what cout is and what is going on here: http://www.cplusplus.com/reference/iostream/cout/
Further, while its quick to do and it works, this is not exactly a good advice to simply add using namespace std; at the top of your code. For detailed correct approach, please read the answers to this related SO question.
I also experienced the same error, "NPM package not installed correctly", while creating a Node.js project in Visual Studio 2015.
I resolved my issue by performing two steps:
Delete all files present in this location:
C:\Users\<Your User Name>\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache
Restart Visual Studio.
Open Visual Studio and go to menu Tools ? NuGet Package Manager ? Package Manager Settings ?
On the left side: You will see a drop down list: select Node.js, Tools ? Npm ? ClearCache ? *OK
Then again try to create the project. It resolved my issue.
I apologize if this answer seems like duplication of previous answers. I just wanted to show an updated (tested through POSH 5.0) way of solving this. The previous answers were pre-3.0 and not as efficient as modern solutions.
The documentation isn't clear on this, but Get-ChildItem -Recurse -Exclude only matches exclusion on the leaf (Split-Path $_.FullName -Leaf), not the parent path (Split-Path $_.FullName -Parent). Matching the exclusion will just remove the item with the matching leaf; Get-ChildItem will still recurse into that leaf.
Get-ChildItem -Path $folder -Recurse |
? { $_.PsIsContainer -and $_.FullName -inotmatch 'archive' }
Note: Same answer as @CB.
Get-ChildItem -Path $folder -Directory -Recurse |
? { $_.FullName -inotmatch 'archive' }
Note: Updated answer from @CB.
This specifically targets directories while excluding leafs with the Exclude parameter, and parents with the ilike (case-insensitive like) comparison:
#Requires -Version 3.0
[string[]]$Paths = @('C:\Temp', 'D:\Temp')
[string[]]$Excludes = @('*archive*', '*Archive*', '*ARCHIVE*', '*archival*')
$files = Get-ChildItem $Paths -Directory -Recurse -Exclude $Excludes | %{
$allowed = $true
foreach ($exclude in $Excludes) {
if ((Split-Path $_.FullName -Parent) -ilike $exclude) {
$allowed = $false
break
}
}
if ($allowed) {
$_
}
}
Note: If you want your $Excludes to be case-sensitive, there are two steps:
Exclude parameter from Get-ChildItem.if condition to:
if ($_.FullName -clike $exclude) {Note: This code has redundancy that I would never implement in production. You should simplify this quite a bit to fit your exact needs. It serves well as a verbose example.
I made a PHP script to make it easier. Create an app. In the Graph API Explorer select your App and get a user token with manage_pages and publish_pages permission. Find your page's ID at the bottom of its About page. Fill in the config vars and run the script.
<?php
$args=[
'usertoken'=>'',
'appid'=>'',
'appsecret'=>'',
'pageid'=>''
];
echo generate_token($args);
function generate_token($args){
$r=json_decode(file_get_contents("https://graph.facebook.com/v2.8/oauth/access_token?grant_type=fb_exchange_token&client_id={$args['appid']}&client_secret={$args['appsecret']}&fb_exchange_token={$args['usertoken']}")); // get long-lived token
$longtoken=$r->access_token;
$r=json_decode(file_get_contents("https://graph.facebook.com/v2.8/me?access_token={$longtoken}")); // get user id
$userid=$r->id;
$r=json_decode(file_get_contents("https://graph.facebook.com/v2.8/{$userid}/accounts?access_token={$longtoken}")); // get permanent token
foreach($r->data as $d) if($d->id==$args['pageid']) return $d->access_token;
}
Answer to an old question as no answer here seem to address the 'warning' problem (explanation follows)
Basically, in this case of checking if a key exists in an array, isset
and array_key_exists
So how do we check if a key exists which value may be null in a variable
without getting a warning, without missing the existing key when its value is null (what were the PHP devs thinking would also be an interesting question, but certainly not relevant on SO). And of course we don't want to use @
isset($var[$key]); // silent but misses null values
array_key_exists($key, $var); // works but warning if $var not defined/array
It seems is_array should be involved in the equation, but it gives a warning if $var is not defined, so that could be a solution:
if (isset($var[$key]) ||
isset($var) && is_array($var) && array_key_exists($key, $var)) ...
which is likely to be faster if the tests are mainly on non-null values. Otherwise for an array with mostly null values
if (isset($var) && is_array($var) && array_key_exists($key, $var)) ...
will do the work.
You can use a constant (i.e. a static, final variable) as the parameter for an annotation. As a quick example, I use something like this fairly often:
import org.junit.Test;
import static org.junit.Assert.*;
public class MyTestClass
{
private static final int TEST_TIMEOUT = 60000; // one minute per test
@Test(timeout=TEST_TIMEOUT)
public void testJDK()
{
assertTrue("Something is very wrong", Boolean.TRUE);
}
}
Note that it's possible to pass the TEST_TIMEOUT constant straight into the annotation.
Offhand, I don't recall ever having tried this with an array, so you may be running into some issues with slight differences in how arrays are represented as annotation parameters compared to Java variables? But as for the other part of your question, you could definitely use a constant String without any problems.
EDIT: I've just tried this with a String array, and didn't run into the problem you mentioned - however the compiler did tell me that the "attribute value must be constant" despite the array being defined as public static final String[]. Perhaps it doesn't like the fact that arrays are mutable? Hmm...
This error is caused by a line of code in /usr/share/phpmyadmin/libraries/sql.lib.php.
It seems when I installed phpMyAdmin using apt, the version in the repository (phpMyAdmin v4.6.6) is not fully compatible with PHP 7.2. There is a newer version available on the official website (v4.8 as of writing), which fixes these compatibility issues with PHP 7.2.
You can download the latest version and install it manually or wait for the repositories to update with the newer version.
Alternatively, you can make a small change to sql.lib.php to fix the error.
Firstly, backup sql.lib.php before editing.
1-interminal:
sudo cp /usr/share/phpmyadmin/libraries/sql.lib.php /usr/share/phpmyadmin/libraries/sql.lib.php.bak
2-Edit sql.lib.php. Using vi:
sudo vi /usr/share/phpmyadmin/libraries/sql.lib.php
OR Using nano:
sudo nano /usr/share/phpmyadmin/libraries/sql.lib.php
Press CTRL + W (for nano) or ? (for vi/vim) and search for (count($analyzed_sql_results['select_expr'] == 1)
Replace it with ((count($analyzed_sql_results['select_expr']) == 1)
Save file and exit. (Press CTRL + X, press Y and then press ENTER for nano users / (for vi/vim) hit ESC then type :wq and press ENTER)
To get the output of ls, use stdout=subprocess.PIPE.
>>> proc = subprocess.Popen('ls', stdout=subprocess.PIPE)
>>> output = proc.stdout.read()
>>> print output
bar
baz
foo
The command cdrecord --help outputs to stderr, so you need to pipe that indstead. You should also break up the command into a list of tokens as I've done below, or the alternative is to pass the shell=True argument but this fires up a fully-blown shell which can be dangerous if you don't control the contents of the command string.
>>> proc = subprocess.Popen(['cdrecord', '--help'], stderr=subprocess.PIPE)
>>> output = proc.stderr.read()
>>> print output
Usage: wodim [options] track1...trackn
Options:
-version print version information and exit
dev=target SCSI target to use as CD/DVD-Recorder
gracetime=# set the grace time before starting to write to #.
...
If you have a command that outputs to both stdout and stderr and you want to merge them, you can do that by piping stderr to stdout and then catching stdout.
subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
As mentioned by Chris Morgan, you should be using proc.communicate() instead of proc.read().
>>> proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> out, err = proc.communicate()
>>> print 'stdout:', out
stdout:
>>> print 'stderr:', err
stderr:Usage: wodim [options] track1...trackn
Options:
-version print version information and exit
dev=target SCSI target to use as CD/DVD-Recorder
gracetime=# set the grace time before starting to write to #.

I'm maybe a little bit late but I'm currently trying to develop a program which can brute force a password protected zip archive. First I tried all commands I found in the internet to extract it through cmd... But it never worked....Every time I tried it, the cmd output said, that the key was wrong but it was right. I think they just disenabled this function in a current version.
What I've done to Solve the problem was to download an older 7zip version(4.?) and to use this for extracting through cmd.
This is the command: "C:/Program Files (86)/old7-zip/7z.exe" x -pKey "C:/YOURE_ZIP_PATH"
The first value("C:/Program Files (86)/old7-zip/7z.exe") has to be the path where you have installed the old 7zip to. The x is for extract and the -p For you're password. Make sure you put your password without any spaces behind the -p! The last value is your zip archive to extract. The destination where the zip is extracted to will be the current path of cmd. You can change it with: cd YOURE_PATH
Now I let execute this command through java with my password trys. Then I check the error output stream of cmd and if it is null-> then the password is right!
import re

I'm fairly sure the primary monitor is the default. If the app was coded decently, when it's closed, it'll remember where it was last at and will reopen there, but -- as you've noticed -- it isn't a default behavior.
EDIT: The way I usually do it is to have the location stored in the app's settings. On load, if there is no value for them, it defaults to the center of the screen. On closing of the form, it records its position. That way, whenever it opens, it's where it was last. I don't know of a simple way to tell it to launch onto the second monitor the first time automatically, however.

Trey Hunner has a nice blog post outlining several options for merging multiple dictionaries, including (for python3.3+) ChainMap and dictionary unpacking.
just open the hive terminal from the hive folder,after editing (bashrc) and (hive-site.xml) files. Steps-- open hive folder where it is installed. now open terminal from folder.
Another alternative would be to show a Toast/Snackbar on the first back press asking to press back again to Exit, which is a lot less intrusive than showing an AlertDialog to confirm if user wants to exit the app.
You can use the DoubleBackPress Android Library to achieve this with a few lines of code. Example GIF showing similar behaviour.
To begin with, add the dependency to your application :
dependencies {
implementation 'com.github.kaushikthedeveloper:double-back-press:0.0.1'
}
Next, in your Activity, implement the required behaviour.
// set the Toast to be shown on FirstBackPress (ToastDisplay - builtin template)
// can be replaced by custom action (new FirstBackPressAction{...})
FirstBackPressAction firstBackPressAction = new ToastDisplay().standard(this);
// set the Action on DoubleBackPress
DoubleBackPressAction doubleBackPressAction = new DoubleBackPressAction() {
@Override
public void actionCall() {
// TODO : Exit the application
finish();
System.exit(0);
}
};
// setup DoubleBackPress behaviour : close the current Activity
DoubleBackPress doubleBackPress = new DoubleBackPress()
.withDoublePressDuration(3000) // msec - wait for second back press
.withFirstBackPressAction(firstBackPressAction)
.withDoubleBackPressAction(doubleBackPressAction);
Finally, set this as the behaviour on back press.
@Override
public void onBackPressed() {
doubleBackPress.onBackPressed();
}
yum install java-1.8.0
and then:
alternatives --config java
and check:
java -version
You should use Task.Delay instead of Sleep for async programming and then use Task.WhenAll to combine the task results. The tasks would run in parallel.
public class Program
{
static void Main(string[] args)
{
Go();
}
public static void Go()
{
GoAsync();
Console.ReadLine();
}
public static async void GoAsync()
{
Console.WriteLine("Starting");
var task1 = Sleep(5000);
var task2 = Sleep(3000);
int[] result = await Task.WhenAll(task1, task2);
Console.WriteLine("Slept for a total of " + result.Sum() + " ms");
}
private async static Task<int> Sleep(int ms)
{
Console.WriteLine("Sleeping for {0} at {1}", ms, Environment.TickCount);
await Task.Delay(ms);
Console.WriteLine("Sleeping for {0} finished at {1}", ms, Environment.TickCount);
return ms;
}
}
Additionally, if it's a folder to be removed and it's subsequent child folders or files, use:
git rm -r foldername
Try calling the .load() method before the .play() method on the audio or video tag... which will be HTMLAudioElement or HTMLVideoElement respectively. That was the only way it would work on the iPad for me!
You want getActivity() inside your class. It's better to use
yourclassname.this.getActivity()
Try this. It's helpful for you.
You can directly go to Web IDE and upload your folder there.
Steps:
In some cases you may not be able to directly upload entire folder containing folders, In such cases, you will have to create directory structure yourself.
I'm going to show you how you can easily define iterators for your custom containers, but just in case I have created a c++11 library that allows you to easily create custom iterators with custom behavior for any type of container, contiguous or non-contiguous.
You can find it on Github
Here are the simple steps to creating and using custom iterators:
typedef blRawIterator< Type > iterator;typedef blRawIterator< const Type > const_iterator;iterator begin(){return iterator(&m_data[0]);};const_iterator cbegin()const{return const_iterator(&m_data[0]);};Finally, onto defining our custom iterator classes:
NOTE: When defining custom iterators, we derive from the standard iterator categories to let STL algorithms know the type of iterator we've made.
In this example, I define a random access iterator and a reverse random access iterator:
//-------------------------------------------------------------------
// Raw iterator with random access
//-------------------------------------------------------------------
template<typename blDataType>
class blRawIterator
{
public:
using iterator_category = std::random_access_iterator_tag;
using value_type = blDataType;
using difference_type = std::ptrdiff_t;
using pointer = blDataType*;
using reference = blDataType&;
public:
blRawIterator(blDataType* ptr = nullptr){m_ptr = ptr;}
blRawIterator(const blRawIterator<blDataType>& rawIterator) = default;
~blRawIterator(){}
blRawIterator<blDataType>& operator=(const blRawIterator<blDataType>& rawIterator) = default;
blRawIterator<blDataType>& operator=(blDataType* ptr){m_ptr = ptr;return (*this);}
operator bool()const
{
if(m_ptr)
return true;
else
return false;
}
bool operator==(const blRawIterator<blDataType>& rawIterator)const{return (m_ptr == rawIterator.getConstPtr());}
bool operator!=(const blRawIterator<blDataType>& rawIterator)const{return (m_ptr != rawIterator.getConstPtr());}
blRawIterator<blDataType>& operator+=(const difference_type& movement){m_ptr += movement;return (*this);}
blRawIterator<blDataType>& operator-=(const difference_type& movement){m_ptr -= movement;return (*this);}
blRawIterator<blDataType>& operator++(){++m_ptr;return (*this);}
blRawIterator<blDataType>& operator--(){--m_ptr;return (*this);}
blRawIterator<blDataType> operator++(int){auto temp(*this);++m_ptr;return temp;}
blRawIterator<blDataType> operator--(int){auto temp(*this);--m_ptr;return temp;}
blRawIterator<blDataType> operator+(const difference_type& movement){auto oldPtr = m_ptr;m_ptr+=movement;auto temp(*this);m_ptr = oldPtr;return temp;}
blRawIterator<blDataType> operator-(const difference_type& movement){auto oldPtr = m_ptr;m_ptr-=movement;auto temp(*this);m_ptr = oldPtr;return temp;}
difference_type operator-(const blRawIterator<blDataType>& rawIterator){return std::distance(rawIterator.getPtr(),this->getPtr());}
blDataType& operator*(){return *m_ptr;}
const blDataType& operator*()const{return *m_ptr;}
blDataType* operator->(){return m_ptr;}
blDataType* getPtr()const{return m_ptr;}
const blDataType* getConstPtr()const{return m_ptr;}

blRawIterator<blDataType> base(){blRawIterator<blDataType> forwardIterator(this->m_ptr); ++forwardIterator; return forwardIterator;}

On Ubuntu you should be able to install the necessary PDO parts from apt using sudo apt-get install php5-mysql
There is no limitation between using PDO and mysql_ simultaneously. You will however need to create two connections to your DB, one with mysql_ and one using PDO.
You can append and set the Value attribute with text:
$("#id").append($('<option></option>').attr("value", '').text(''));
$("#id").append($('<option></option>').attr("value", '4').text('Financial Institutions'));
use the itoa() function included in stdlib.h
char buffer[7]; //the ASCII of the integer will be stored in this char array
itoa(-31596,buffer,10); //(integer, yourBuffer, base)
Workaround (not a clean, nice (or even working! see comments) solution):
Disable his credentials one time.
You can move your HTTP authentication logic to PHP by sending the appropriate headers (if not logged in):
Header('WWW-Authenticate: Basic realm="protected area"');
Header('HTTP/1.0 401 Unauthorized');
And parsing the input with:
$_SERVER['PHP_AUTH_USER'] // httpauth-user
$_SERVER['PHP_AUTH_PW'] // httpauth-password
So disabling his credentials one time should be trivial.
The precise wording of the question makes me think it's impossible.
return to me means you have a function, which you have passed a string as a parameter.
You cannot change this parameter. Assigning to it will only change the value of the parameter within the function, not the passed in string. E.g.
>>> def removeAndReturnLastCharacter(a):
c = a[-1]
a = a[:-1]
return c
>>> b = "Hello, Gaukler!"
>>> removeAndReturnLastCharacter(b)
!
>>> b # b has not been changed
Hello, Gaukler!
… how can I delete an item from a dictionary to return a copy (i.e., not modifying the original)?
A dict is the wrong data structure to use for this.
Sure, copying the dict and popping from the copy works, and so does building a new dict with a comprehension, but all that copying takes time—you've replaced a constant-time operation with a linear-time one. And all those copies alive at once take space—linear space per copy.
Other data structures, like hash array mapped tries, are designed for exactly this kind of use case: adding or removing an element returns a copy in logarithmic time, sharing most of its storage with the original.1
Of course there are some downsides. Performance is logarithmic rather than constant (although with a large base, usually 32-128). And, while you can make the non-mutating API identical to dict, the "mutating" API is obviously different. And, most of all, there's no HAMT batteries included with Python.2
The pyrsistent library is a pretty solid implementation of HAMT-based dict-replacements (and various other types) for Python. It even has a nifty evolver API for porting existing mutating code to persistent code as smoothly as possible. But if you want to be explicit about returning copies rather than mutating, you just use it like this:
>>> from pyrsistent import m
>>> d1 = m(a=1, b=2)
>>> d2 = d1.set('c', 3)
>>> d3 = d1.remove('a')
>>> d1
pmap({'a': 1, 'b': 2})
>>> d2
pmap({'c': 3, 'a': 1, 'b': 2})
>>> d3
pmap({'b': 2})
That d3 = d1.remove('a') is exactly what the question is asking for.
If you've got mutable data structures like dict and list embedded in the pmap, you'll still have aliasing issues—you can only fix that by going immutable all the way down, embedding pmaps and pvectors.
1. HAMTs have also become popular in languages like Scala, Clojure, Haskell because they play very nicely with lock-free programming and software transactional memory, but neither of those is very relevant in Python.
2. In fact, there is an HAMT in the stdlib, used in the implementation of contextvars. The earlier withdrawn PEP explains why. But this is a hidden implementation detail of the library, not a public collection type.
For incorporate volley in android studio,
the switch to android view and open the build:gradle(Module:app) file and append the following line in the dependency area:
compile 'com.mcxiaoke.volley:library-aar:1.0.0'
Now synchronise your project and also build your project.
Many of the Python 2 implementations here will fail if there is no controlling terminal when you call this script. You can check sys.stdout.isatty() to determine if this is in fact a terminal, but that will exclude a bunch of cases, so I believe the most pythonic way to figure out the terminal size is to use the builtin curses package.
import curses
w = curses.initscr()
height, width = w.getmaxyx()
ActiveSheet.Range("A10000").End(xlup).offset(1,0).Select
public interface IContainsMyModel
{
ViewModel Model { get; }
}
public class ViewModel : IContainsMyModel
{
public string MyProperty { set; get; }
public ViewModel Model { get { return this; } }
}
public class Composition : IContainsMyModel
{
public ViewModel ViewModel { get; set; }
}
Use IContainsMyModel in your layout.
Solved. Interfaces rule.
If you are looking for delete cache of your own application then simply delete your cache directory and its all done !
public static void deleteCache(Context context) {
try {
File dir = context.getCacheDir();
deleteDir(dir);
} catch (Exception e) { e.printStackTrace();}
}
public static boolean deleteDir(File dir) {
if (dir != null && dir.isDirectory()) {
String[] children = dir.list();
for (int i = 0; i < children.length; i++) {
boolean success = deleteDir(new File(dir, children[i]));
if (!success) {
return false;
}
}
return dir.delete();
} else if(dir!= null && dir.isFile()) {
return dir.delete();
} else {
return false;
}
}
The inner finally is executed prior to throwing the exception to the outer block.
public class TryCatchFinally {
public static void main(String[] args) throws Exception {
try{
System.out.println('A');
try{
System.out.println('B');
throw new Exception("threw exception in B");
}
finally
{
System.out.println('X');
}
//any code here in the first try block
//is unreachable if an exception occurs in the second try block
}
catch(Exception e)
{
System.out.println('Y');
}
finally
{
System.out.println('Z');
}
}
}
Results in
A
B
X
Y

use 'any'
dict = {}
if any(dict) :

# dictionary is empty
You can extend the timeout: inherit the original WebClient class and override the webrequest getter to set your own timeout, like in the following example.
MyWebClient was a private class in my case:
private class MyWebClient : WebClient
{
protected override WebRequest GetWebRequest(Uri uri)
{
WebRequest w = base.GetWebRequest(uri);
w.Timeout = 20 * 60 * 1000;
return w;
}
}
I think you want to turn any given URL string into a HASH?
You can try http://www.ruby-doc.org/stdlib/libdoc/cgi/rdoc/classes/CGI.html#M000075
require 'cgi'
CGI::parse('param1=value1¶m2=value2¶m3=value3')
returns
{"param1"=>["value1"], "param2"=>["value2"], "param3"=>["value3"]}
This way work for me in Swift 2 iOS 8.x:
PS (this method dont require to override orientation functions like shouldautorotate on every viewController, just one method on AppDelegate)
Check the "requires full screen" in you project general info.
So, on AppDelegate.swift make a variable:
var enableAllOrientation = false
So, put also this func:
func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
if (enableAllOrientation == true){
return UIInterfaceOrientationMask.All
}
return UIInterfaceOrientationMask.Portrait
}
So, in every class in your project you can set this var in viewWillAppear:
override func viewWillAppear(animated: Bool)
{
super.viewWillAppear(animated)
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.enableAllOrientation = true
}
If you need to make a choices based on the device type you can do this:
override func viewWillAppear(animated: Bool)
{
super.viewWillAppear(animated)
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
switch UIDevice.currentDevice().userInterfaceIdiom {
case .Phone:
// It's an iPhone
print(" - Only portrait mode to iPhone")
appDelegate.enableAllOrientation = false
case .Pad:
// It's an iPad
print(" - All orientation mode enabled on iPad")
appDelegate.enableAllOrientation = true
case .Unspecified:
// Uh, oh! What could it be?
appDelegate.enableAllOrientation = false
}
}

So, as was mentioned in a couple comments containing the data in an array is simpler but the solution does not scale well in terms of efficiency as the data set size increases. You really should only use an iterator when you want to access a random object in the array, otherwise, generators are the way to go. Below I have prototyped a reader function which reads each json object individually and returns a generator.
The basic idea is to signal the reader to split on the carriage character "\n" (or "\r\n" for Windows). Python can do this with the file.readline() function.
import json
def json_reader(filename):
with open(filename) as f:
for line in f:
yield json.loads(line)
However, this method only really works when the file is written as you have it -- with each object separated by a newline character. Below I wrote an example of a writer that separates an array of json objects and saves each one on a new line.
def json_writer(file, json_objects):
with open(file, "w") as f:
for jsonobj in json_objects:
jsonstr = json.dumps(jsonobj)
f.write(jsonstr + "\n")
You could also do the same operation with file.writelines() and a list comprehension:
...
json_strs = [json.dumps(j) + "\n" for j in json_objects]
f.writelines(json_strs)
...
And if you wanted to append the data instead of writing a new file just change open(file, "w") to open(file, "a").
In the end I find this helps a great deal not only with readability when I try and open json files in a text editor but also in terms of using memory more efficiently.
On that note if you change your mind at some point and you want a list out of the reader, Python allows you to put a generator function inside of a list and populate the list automatically. In other words, just write
lst = list(json_reader(file))
I had similar problem. In git site after user clicking on clone or download button, while copying the cloned url there are 2 options to select ssh and https. I selected https url to clone and it worked.
Underscores look ugly in package names. For what is worth, in case of names compound of three or more words I use initials (for example: com.company.app.ingresoegresofijo (ingreso/egreso fijo) -> com.company.app.iefijo) and then document the package purpose in package-info.java.
All cookies are client and server
There is no difference. A regular cookie can be set server side or client side. The 'classic' cookie will be sent back with each request. A cookie that is set by the server, will be sent to the client in a response. The server only sends the cookie when it is explicitly set or changed, while the client sends the cookie on each request.
But essentially it's the same cookie.
But, behavior can change
A cookie is basically a name=value pair, but after the value can be a bunch of semi-colon separated attributes that affect the behavior of the cookie if it is so implemented by the client (or server).
Those attributes can be about lifetime, context and various security settings.
HTTP-only (is not server-only)
One of those attributes can be set by a server to indicate that it's an HTTP-only cookie. This means that the cookie is still sent back and forth, but it won't be available in JavaScript. Do note, though, that the cookie is still there! It's only a built in protection in the browser, but if somebody would use a ridiculously old browser like IE5, or some custom client, they can actually read the cookie!
So it seems like there are 'server cookies', but there are actually not. Those cookies are still sent to the client. On the client there is no way to prevent a cookie from being sent to the server.
Alternatives to achieve 'only-ness'
If you want to store a value only on the server, or only on the client, then you'd need some other kind of storage, like a file or database on the server, or Local Storage on the client.
It's all about the selector. You can change your code to be something like this:
<div class="formbuilder">
<div class="active">Heading</div>
<div>1</div>
<div>2</div>
<div>3</div>
<div>4</div>
</div>
Then use this javascript:
$(document).ready(function () {
$('.formbuilder div').on('click', function () {
$('.formbuilder div').removeClass('active');
$(this).addClass('active');
});
});
The example in a working jsfiddle
See this api about the selector I used: http://api.jquery.com/descendant-selector/
There is no defined maximum size for HTTP POST requests. If you notice such a limit then it's an arbitrary limitation of your HTTP Server/Client.
You might get a better answer if you tell how big the XML is.
I made a bug to Google about the fact that there's no reliable way to select the page on a BottomNavigationView: https://code.google.com/p/android/issues/detail?id=233697
NavigationView apparently had a similar issue, which they fixed by adding a new setCheckedItem() method.
This can be solved in O(n^2) using dynamic programming.
Process the input elements in order and maintain a list of tuples for each element. Each tuple (A,B), for the element i will denotes, A = length of longest increasing sub-sequence ending at i and B = index of predecessor of list[i] in the longest increasing sub-sequence ending at list[i].
Start from element 1, the list of tuple for element 1 will be [(1,0)] for element i, scan the list 0..i and find element list[k] such that list[k] < list[i], the value of A for element i, Ai will be Ak + 1 and Bi will be k. If there are multiple such elements, add them to the list of tuples for element i.
In the end, find all the elements with max value of A (length of LIS ending at element) and backtrack using the tuples to get the list.
I have shared the code for same at http://www.edufyme.com/code/?id=66f041e16a60928b05a7e228a89c3799
Yo,
This is how you do it if you want just one type of holder stick when it starts getting out of the screen (we are not caring about any sections). There is only one way without breaking the internal RecyclerView logic of recycling items and that is to inflate additional view on top of the recyclerView's header item and pass data into it. I'll let the code speak.
import android.graphics.Canvas
import android.graphics.Rect
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.annotation.LayoutRes
import androidx.recyclerview.widget.RecyclerView
class StickyHeaderItemDecoration(@LayoutRes private val headerId: Int, private val HEADER_TYPE: Int) : RecyclerView.ItemDecoration() {
private lateinit var stickyHeaderView: View
private lateinit var headerView: View
private var sticked = false
// executes on each bind and sets the stickyHeaderView
override fun getItemOffsets(outRect: Rect, view: View, parent: RecyclerView, state: RecyclerView.State) {
super.getItemOffsets(outRect, view, parent, state)
val position = parent.getChildAdapterPosition(view)
val adapter = parent.adapter ?: return
val viewType = adapter.getItemViewType(position)
if (viewType == HEADER_TYPE) {
headerView = view
}
}
override fun onDrawOver(c: Canvas, parent: RecyclerView, state: RecyclerView.State) {
super.onDrawOver(c, parent, state)
if (::headerView.isInitialized) {
if (headerView.y <= 0 && !sticked) {
stickyHeaderView = createHeaderView(parent)
fixLayoutSize(parent, stickyHeaderView)
sticked = true
}
if (headerView.y > 0 && sticked) {
sticked = false
}
if (sticked) {
drawStickedHeader(c)
}
}
}
private fun createHeaderView(parent: RecyclerView) = LayoutInflater.from(parent.context).inflate(headerId, parent, false)
private fun drawStickedHeader(c: Canvas) {
c.save()
c.translate(0f, Math.max(0f, stickyHeaderView.top.toFloat() - stickyHeaderView.height.toFloat()))
headerView.draw(c)
c.restore()
}
private fun fixLayoutSize(parent: ViewGroup, view: View) {
// Specs for parent (RecyclerView)
val widthSpec = View.MeasureSpec.makeMeasureSpec(parent.width, View.MeasureSpec.EXACTLY)
val heightSpec = View.MeasureSpec.makeMeasureSpec(parent.height, View.MeasureSpec.UNSPECIFIED)
// Specs for children (headers)
val childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec, parent.paddingLeft + parent.paddingRight, view.getLayoutParams().width)
val childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec, parent.paddingTop + parent.paddingBottom, view.getLayoutParams().height)
view.measure(childWidthSpec, childHeightSpec)
view.layout(0, 0, view.measuredWidth, view.measuredHeight)
}
}
And then you just do this in your adapter:
override fun onAttachedToRecyclerView(recyclerView: RecyclerView) {
super.onAttachedToRecyclerView(recyclerView)
recyclerView.addItemDecoration(StickyHeaderItemDecoration(R.layout.item_time_filter, YOUR_STICKY_VIEW_HOLDER_TYPE))
}
Where YOUR_STICKY_VIEW_HOLDER_TYPE is viewType of your what is supposed to be sticky holder.
When I got this error, it turned out I had a call to the map function inside my "async" function, so this error message was actually referring to the map function not being marked as "async". I got around this issue by taking the "await" call out of the map function and coming up with some other way of getting the expected behavior.
var myfunction = async function(x,y) {
....
someArray.map(someVariable => { // <- This was the function giving the error
return await someFunction(someVariable);
});
}
og_date = "2012-10-01";
console.log(og_date); // => "2012-10-01"
console.log(og_date.split('-')); // => [ '2012', '10', '01' ]
og_date.value would only work if the date were stored as a property on the og_date object.
Such as: var og_date = {}; og_date.value="2012-10-01";
In that case, your original console.log would work.

Assuming there are two dictionaries with exact same keys, below is the most succinct way of doing it (python3 should be used for both the solution).
d1 = {'a': 1, 'b': 2, 'c':3}
d2 = {'a': 5, 'b': 6, 'c':7}
# get keys from one of the dictionary
ks = [k for k in d1.keys()]
print(ks)
['a', 'b', 'c']
# call values from each dictionary on available keys
d_merged = {k: (d1[k], d2[k]) for k in ks}
print(d_merged)
{'a': (1, 5), 'b': (2, 6), 'c': (3, 7)}
# to merge values as list
d_merged = {k: [d1[k], d2[k]] for k in ks}
print(d_merged)
{'a': [1, 5], 'b': [2, 6], 'c': [3, 7]}
If there are two dictionaries with some common keys, but a few different keys, a list of all the keys should be prepared.
d1 = {'a': 1, 'b': 2, 'c':3, 'd': 9}
d2 = {'a': 5, 'b': 6, 'c':7, 'e': 4}
# get keys from one of the dictionary
d1_ks = [k for k in d1.keys()]
d2_ks = [k for k in d2.keys()]
all_ks = set(d1_ks + d2_ks)
print(all_ks)
['a', 'b', 'c', 'd', 'e']
# call values from each dictionary on available keys
d_merged = {k: [d1.get(k), d2.get(k)] for k in all_ks}
print(d_merged)
{'d': [9, None], 'a': [1, 5], 'b': [2, 6], 'c': [3, 7], 'e': [None, 4]}
I spent a few hours trying to fix the issue and I finally got it - the SQL Server Browser was "Stopped". The fix is to change it to "Automatic" mode:
If it is disabled, go to Control Panel->Administrative Tools->Services, and look for the SQL Server Agent. Right-click, and select "Properties." From the "Startup Type" dropdown, change from "Disabled" to "Automatic".

You can create a function:
CREATE FUNCTION dbo.[Check_existance_of_carriage_return_line_feed]
(
@String VARCHAR(MAX)
)
RETURNS VARCHAR(MAX)
BEGIN
DECLARE @RETURN_BOOLEAN INT
;WITH N1 (n) AS (SELECT 1 UNION ALL SELECT 1),
N2 (n) AS (SELECT 1 FROM N1 AS X, N1 AS Y),
N3 (n) AS (SELECT 1 FROM N2 AS X, N2 AS Y),
N4 (n) AS (SELECT ROW_NUMBER() OVER(ORDER BY X.n)
FROM N3 AS X, N3 AS Y)
SELECT @RETURN_BOOLEAN =COUNT(*)
FROM N4 Nums
WHERE Nums.n<=LEN(@String) AND ASCII(SUBSTRING(@String,Nums.n,1))
IN (13,10)
RETURN (CASE WHEN @RETURN_BOOLEAN >0 THEN 'TRUE' ELSE 'FALSE' END)
END
GO
Then you can simple run a query like this:
SELECT column_name, dbo.[Check_existance_of_carriage_return_line_feed] (column_name)
AS [Boolean]
FROM [table_name]
