If efficiency is an issue and you have to build multiple different n-grams (up to a hundred as you say), but you want to use pure python I would do:
from itertools import chain
def n_grams(seq, n=1):
"""Returns an itirator over the n-grams given a listTokens"""
shiftToken = lambda i: (el for j,el in enumerate(seq) if j>=i)
shiftedTokens = (shiftToken(i) for i in range(n))
tupleNGrams = zip(*shiftedTokens)
return tupleNGrams # if join in generator : (" ".join(i) for i in tupleNGrams)
def range_ngrams(listTokens, ngramRange=(1,2)):
"""Returns an itirator over all n-grams for n in range(ngramRange) given a listTokens."""
return chain(*(n_grams(listTokens, i) for i in range(*ngramRange)))
Usage :
>>> input_list = input_list = 'test the ngrams generator'.split()
>>> list(range_ngrams(input_list, ngramRange=(1,3)))
[('test',), ('the',), ('ngrams',), ('generator',), ('test', 'the'), ('the', 'ngrams'), ('ngrams', 'generator'), ('test', 'the', 'ngrams'), ('the', 'ngrams', 'generator')]
~Same speed as NLTK:
import nltk
%%timeit
input_list = 'test the ngrams interator vs nltk '*10**6
nltk.ngrams(input_list,n=5)
# 7.02 ms ± 79 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
%%timeit
input_list = 'test the ngrams interator vs nltk '*10**6
n_grams(input_list,n=5)
# 7.01 ms ± 103 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
%%timeit
input_list = 'test the ngrams interator vs nltk '*10**6

nltk.ngrams(input_list,n=2)

nltk.ngrams(input_list,n=4)
nltk.ngrams(input_list,n=5)
# 7.32 ms ± 241 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
%%timeit
input_list = 'test the ngrams interator vs nltk '*10**6
range_ngrams(input_list, ngramRange=(1,6))
# 7.13 ms ± 165 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

I followed this simple steps to do this stuff.
DialogFragmentCallbackInterface
with some method like callBackMethod(Object data)
. Which you would calling to pass data.DialogFragmentCallbackInterface
interface in your fragment like MyFragment implements DialogFragmentCallbackInterface
At time of DialogFragment
creation set your invoking fragment MyFragment
as target fragment who created DialogFragment
use myDialogFragment.setTargetFragment(this, 0)
check setTargetFragment (Fragment fragment, int requestCode)
MyDialogFragment dialogFrag = new MyDialogFragment();
dialogFrag.setTargetFragment(this, 1);
Get your target fragment object into your DialogFragment
by calling getTargetFragment()
and cast it to DialogFragmentCallbackInterface
.Now you can use this interface to send data to your fragment.
DialogFragmentCallbackInterface callback =
(DialogFragmentCallbackInterface) getTargetFragment();
callback.callBackMethod(Object data);
That's it all done! just make sure you have implemented this interface in your fragment.
To handle One-To-Many relationships in Django you need to use ForeignKey
.
The documentation on ForeignKey is very comprehensive and should answer all the questions you have:
https://docs.djangoproject.com/en/dev/ref/models/fields/#foreignkey
The current structure in your example allows each Dude to have one number, and each number to belong to multiple Dudes (same with Business).
If you want the reverse relationship, you would need to add two ForeignKey fields to your PhoneNumber model, one to Dude and one to Business. This would allow each number to belong to either one Dude or one Business, and have Dudes and Businesses able to own multiple Numbers. I think this might be what you are after.
class Business(models.Model):
...
class Dude(models.Model):
...
class PhoneNumber(models.Model):
dude = models.ForeignKey(Dude)
business = models.ForeignKey(Business)
or if you just want a line
TextView line = new TextView(this);
line.setBackgroundResource(android.R.color.holo_red_dark);
line.setHeight((int) Utility.convertDpToPixel(1,this));
You can do it as follow:
#include < iostream >
using namespace std;
int main () {
string texts[] = {"Apple", "Banana", "Orange"};
for( unsigned int a = 0; a < sizeof(texts) / 32; a++ ) { // 32 is the size of string data type
cout << "value of a: " << texts[a] << endl;
}
return 0;
}
Actually without PDB files and symbolic information they have it would be impossible to create a successful crash report (memory dump files) and Microsoft would not have the complete picture what caused the problem.
And so having PDB improves crash reporting.
A canvas has 2 sizes, the dimension of the pixels in the canvas (it's backingstore or drawingBuffer) and the display size. The number of pixels is set using the the canvas attributes. In HTML
<canvas width="400" height="300"></canvas>
Or in JavaScript
someCanvasElement.width = 400;
someCanvasElement.height = 300;
Separate from that are the canvas's CSS style width and height
In CSS
canvas { /* or some other selector */
width: 500px;
height: 400px;
}
Or in JavaScript
canvas.style.width = "500px";
canvas.style.height = "400px";
The arguably best way to make a canvas 1x1 pixels is to ALWAYS USE CSS to choose the size then write a tiny bit of JavaScript to make the number of pixels match that size.
function resizeCanvasToDisplaySize(canvas) {
// look up the size the canvas is being displayed
const width = canvas.clientWidth;
const height = canvas.clientHeight;
// If it's resolution does not match change it
if (canvas.width !== width || canvas.height !== height) {
canvas.width = width;
canvas.height = height;
return true;
}
return false;
}
Why is this the best way? Because it works in most cases without having to change any code.

You will get the help page with following line:

Kotlin and Numeric keyboard
If you are using the numeric keyboard you have to dismiss the keyboard, it will be like:
editText.setOnEditorActionListener { v, actionId, event ->
if (action == EditorInfo.IME_ACTION_DONE || action == EditorInfo.IME_ACTION_NEXT || action == EditorInfo.IME_ACTION_UNSPECIFIED) {
//hide the keyboard
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(windowToken, 0)
//Take action
editValue.clearFocus()
return true
} else {
return false
}
}
As an aside to those that stumble along across this, one nice way to run test level on using the HostingEnvironment call, is if accessing say a UNC share: \example\ that is mapped to ~/example/ you could execute this to get around IIS-Express issues:
#if DEBUG
var fs = new FileStream(@"\\example\file",FileMode.Open, FileAccess.Read);
#else
var fs = new FileStream(HostingEnvironment.MapPath("~/example/file"), FileMode.Open, FileAccess.Read);
#endif
I find that helpful in case you have rights to locally test on a file, but need the env mapping once in production.
I'm surprised noone mentioned the git reflog (http://git-scm.com/docs/git-reflog):
# git reflog
<find the place before your staged anything>
# git reset HEAD@{1}
The reflog is a git history that not only tracks the changes to the repo, but also tracks the user actions (Eg. pull, checkout to different branch, etc) and allows to undo those actions. So instead of unstaging the file that was mistakingly staged, where you can revert to the point where you didn't stage the files.
This is similar to git reset HEAD <file>
but in certain cases may be more granular.
Sorry - not really answering your question, but just pointing yet another way to unstage files that I use quite often (I for one like answers by Ryan Stewart and waldyrious very much.) ;) I hope it helps.
The BLOB datatype is best for storing files.
The following will create a variable length set of arguments of the type of string:
print(String arg1, String... arg2)
You can then refer to arg2
as an array of Strings. This is a new feature in Java 5.
Just to offer you a different angle -
I find it's not a good idea to maintain public variables between function calls. Any variables you need to use should be stored in Subs and Functions and passed as parameters. Once the code is done running, you shouldn't expect the VBA Project to maintain the values of any variables.
The reason for this is that there is just a huge slew of things that can inadvertently reset the VBA Project while using the workbook. When this happens, any public variables get reset to 0.
If you need a value to be stored outside of your subs and functions, I highly recommend using a hidden worksheet with named ranges for any information that needs to persist.
public enum EXIT_CODE {
A(104), B(203);
private int numVal;
EXIT_CODE(int numVal) {
this.numVal = numVal;
}
public int getNumVal() {
return numVal;
}
}
First replace "\n"
with its Html
equavalent "<br>"
then call Html.fromHtml()
on the string. Follow below steps:
String text= model.getMessageBody().toString().replace("\n", "<br>")
textView.setText(Html.fromHtml(Html.fromHtml(text).toString()))
This works perfectly.
I would put an absolutely positioned, z-index: 100;
span (or spans) with the background: url("myImageWithRoundedCorners.jpg");
set on it inside the #mainWrapperDivWithBGImage
.
This is due to the interfering messages
that come on to the page. There are multiple frames on the page which communicate with the page using window message event and object. few of them can be third party services like cookieq
for managing cookies, or may be cartwire
an e-com integration service.
You need to handle the onmessage event to check from where the messages are coming, and then parse the JSON accordingly.
I faced a similar problem, where one of the integration was passing a JSON object and other was passing a string starting with u
You can use System.Web.Script.Serialization.JavaScriptSerializer
:
Dictionary<string, object> dictss = new Dictionary<string, object>(){
{"User", "Mr.Joshua"},
{"Pass", "4324"},
};
string jsonString = (new JavaScriptSerializer()).Serialize((object)dictss);
You certainly want to hack the header to have a proper Ajax Request :
headers = {'X_REQUESTED_WITH' :'XMLHttpRequest',
'ACCEPT': 'application/json, text/javascript, */*; q=0.01',}
request = urllib2.Request(path, data, headers)
response = urllib2.urlopen(request).read()
And to json.loads the POST on the server-side.
Edit : By the way, you have to urllib.urlencode(mydata_dict)
before sending them. If you don't, the POST won't be what the server expect
This question is pretty much answered but I would like to complement X-Istence's and Dana the Sane's answer with a small suggestion.
If you need revision control with some degree of granularity, say daily, you could couple the text dump of both the tables and the schema with a tool like rdiff-backup which does incremental backups. The advantage is that instead of storing snapshots of daily backups, you simply store the differences from the previous day.
With this you have both the advantage of revision control and you don't waste too much space.
In any case, using git directly on big flat files which change very frequently is not a good solution. If your database becomes too big, git will start to have some problems managing the files.
$(selectedDOM).find();
function looking for all dom objects inside the selected DOM. i.e.
<div id="mainDiv">
<p>Paragraph 1</p>
<p>Paragraph 2</p>
<div id="innerDiv">
<a href="#">link</a>
<p>Paragraph 3</p>
</div>
</div>
here if you write;
$("#mainDiv").find("p");
you will get tree p elements together. On the other side,
$("#mainDiv").children("p");
Function searching in the just children DOMs of the selected DOM object. So, by this code you will get just paragraph 1 and paragraph 2. It is so beneficial to prevent browser doing unnecessary progress.
You can use below JavaScript.
window.open('','_self').close();
In a HTML you can use below code
<a href="javascript:close_window();">close</a>
I have tried this in Chrome 61 and IE11 it is working fine. But this is not working with Firefox 57. In Firefox we can only close, windows which opened using below command.
window.open()
You can use two elements, one inside the other, and give the outer one overflow: hidden
and a width equal to the inner element together with a bottom padding so that the shadow on all the other sides are "cut off"
#outer {
width: 100px;
overflow: hidden;
padding-bottom: 10px;
}
#outer > div {
width: 100px;
height: 100px;
background: orange;
-moz-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
-webkit-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
}
Alternatively, float the outer element to cause it to shrink to the size of the inner element. See: http://jsfiddle.net/QJPd5/1/
your understanding is right. For detailed info on {} see bash ref - parameter expansion
'for' and 'while' have different syntax and offer different styles of programmer control for an iteration. Most non-asm languages offer a similar syntax.
With while, you would probably write i=0; while [ $i -lt 10 ]; do echo $i; i=$(( i + 1 )); done
in essence manage everything about the iteration yourself

The second case (new Vue (...)

The first will be used in JS to bootstrap Vue, while either can be used to build up components and templates.

The way to enable to switch from you regular to the root user (AKA “super user”) after authentificating with your Google Computer Engine (GCE) User in the local environment (your Linux server in GCE) is pretty straight forward, in fact it just involves just one command to enable it and another every time to use it:
$ sudo passwd
Enter the new UNIX password: <your new root password>
Retype the new UNIX password: <your new root password>
passwd: password updated successfully
After executing the previous command and once logged with your GCE User you will be able to switch to root anytime by just entering the following command:
$ su
Password: <your newly created root password>
root@intance:/#
As we say in economics “caveat emptor” or buyer be aware: Using the root user is far from a best practice in system’s administration. Using it can be the cause a lot of trouble, from wiping everything in your drives and boot disks without a hiccup to many other nasty stuff that would be laborious to backtrack, troubleshoot and rebuilt. On the other hand, I have never met a SysAdmin that doesn’t think he knows better and root more than he should.
REMEMBER: We humans are programmed in such a way that given enough time at one at some point or another are going to press enter without taking into account that we have escalated to root and I can assure you that it will great source of pain, regret and extra work. PLEASE USE ROOT PRIVILEGES SPARSELY AND WITH EXTREME CARE.
Having said all the boring stuff, Have fun, live on the edge, life is short, you only get to live it once, the more you break the more you learn.
Just to add to things from several of the posts above:
read() -- at least on my system -- returns ssize_t. This is like size_t, except is signed. On my system, it's a long, not an int. You might get compiler warnings if you use int, depending on your system, your compiler, and what warnings you have turned on.

The API docs give some good hints:
print() ? nil
print(obj, ...) ? nil
Writes the given object(s) to ios. Returns
nil
.The stream must be opened for writing. Each given object that isn't a string will be converted by calling its
to_s
method. When called without arguments, prints the contents of$_
.If the output field separator (
$,
) is notnil
, it is inserted between objects. If the output record separator ($\
) is notnil
, it is appended to the output....
puts(obj, ...) ? nil
Writes the given object(s) to ios. Writes a newline after any that do not already end with a newline sequence. Returns
nil
.The stream must be opened for writing. If called with an array argument, writes each element on a new line. Each given object that isn't a string or array will be converted by calling its
to_s
method. If called without arguments, outputs a single newline.
Experimenting a little with the points given above, the differences seem to be:
Called with multiple arguments, print
separates them by the 'output field separator' $,
(which defaults to nothing) while puts
separates them by newlines. puts
also puts a newline after the final argument, while print
does not.
2.1.3 :001 > print 'hello', 'world'

puts
automatically unpacks arrays, while print
does not:

print
with no arguments prints $_
(the last thing read by gets
), while puts
prints a newline:

hello world
=> "hello world\n"
2.1.3 :002 > puts
=> nil
2.1.3 :003 > print

print
writes the output record separator $\
after whatever it prints, while puts
ignores this variable:

Solution for EF4.3
Unique UserName
Add data annotation over column as:
[Index(IsUnique = true)]
[MaxLength(255)] // for code-first implementations
public string UserName{get;set;}
Unique ID , I have added decoration [Key] over my column and done. Same solution as described here: https://msdn.microsoft.com/en-gb/data/jj591583.aspx
IE:
[Key]
public int UserId{get;set;}
Alternative answers
using data annotation
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
[Column("UserId")]
using mapping
mb.Entity<User>()
.HasKey(i => i.UserId);
mb.User<User>()
.Property(i => i.UserId)
.HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity)
.HasColumnName("UserId");
The explanation for how it works:
JUnit wraps your test method in a Statement object so statement and Execute()
runs your test. Then instead of calling statement.Execute()
directly to run your test, JUnit passes the Statement to a TestRule with the @Rule
annotation. The TestRule's "apply" function returns a new Statement given the Statement with your test. The new Statement's Execute()
method can call the test Statement's execute method (or not, or call it multiple times), and do whatever it wants before and after
.
Now, JUnit has a new Statement that does more than just run the test, and it can again pass that to any more rules before finally calling Execute.
I would use this syntax to set the index value into an attribute of the HTML element:
You have to use let
to declare the value rather than #
.
<ul>
<li *ngFor="let item of items; let i = index" [attr.data-index]="i">
{{item}}
</li>
</ul>
<ul>
<li *ngFor="#item of items; #i = index" [attr.data-index]="i">
{{item}}
</li>
</ul>
Here is the updated plunkr: http://plnkr.co/edit/LiCeyKGUapS5JKkRWnUJ?p=preview.
You can write your own function that returns an array of bits. Example how to convert number to bits
example of above line: 2 * 4 = 8 and remainder is 1 so 9 = 1 0 0 1
function numToBit(num){
var number = num
var result = []
while(number >= 1 ){
result.unshift(Math.floor(number%2))
number = number/2
}
return result
}
Read remainders from bottom to top. Digit 1 in the middle to top.
You're not going to be able to modify the caller's shell because it's in a different process context. When child processes inherit your shell's variables, they're inheriting copies themselves.
One thing you can do is to write a script that emits the correct commands for tcsh or sh based how it's invoked. If you're script is "setit" then do:
ln -s setit setit-sh
and
ln -s setit setit-csh
Now either directly or in an alias, you do this from sh
eval `setit-sh`
or this from csh
eval `setit-csh`
setit uses $0 to determine its output style.
This is reminescent of how people use to get the TERM environment variable set.
The advantage here is that setit is just written in whichever shell you like as in:
#!/bin/bash
arg0=$0
arg0=${arg0##*/}
for nv in \
NAME1=VALUE1 \
NAME2=VALUE2
do
if [ x$arg0 = xsetit-sh ]; then
echo 'export '$nv' ;'
elif [ x$arg0 = xsetit-csh ]; then
echo 'setenv '${nv%%=*}' '${nv##*=}' ;'
fi
done
with the symbolic links given above, and the eval of the backquoted expression, this has the desired result.
To simplify invocation for csh, tcsh, or similar shells:
alias dosetit 'eval `setit-csh`'
or for sh, bash, and the like:
alias dosetit='eval `setit-sh`'
One nice thing about this is that you only have to maintain the list in one place.
In theory you could even stick the list in a file and put cat nvpairfilename
between "in" and "do".
This is pretty much how login shell terminal settings used to be done: a script would output statments to be executed in the login shell. An alias would generally be used to make invocation simple, as in "tset vt100". As mentioned in another answer, there is also similar functionality in the INN UseNet news server.
Although we have great answers already, looking through a perspective of a beginner I'd like to add the additional information:
What does map(&:name) mean in Ruby?
This means, that you are passing another method as parameter to the map function. (In reality you're passing a symbol that gets converted into a proc. But this isn't that important in this particular case).
What is important is that you have a method
named name
that will be used by the map method as an argument instead of the traditional block
style.
You can implement a static formatting method or an HTML helper, then use this syntaxe :
@using class_of_method_namespace
...
// HTML page here
@className.MethodName()
or in case of HTML Helper
@Html.MehtodName()
I know it's kinda late to answer but let me answer anyway, some of the answers above are quite complicated hence here is a much simpler take.
SELECT a.table_name child_table, a.column_name child_column, a.constraint_name,
b.table_name parent_table, b.column_name parent_column
FROM all_cons_columns a
JOIN all_constraints c ON a.owner = c.owner AND a.constraint_name = c.constraint_name
join all_cons_columns b on c.owner = b.owner and c.r_constraint_name = b.constraint_name
WHERE c.constraint_type = 'R'
AND a.table_name = 'your table name'

package
: take the compiled code and package it in its distributable format, such as a JAR.
install
: install the package into the local repository, for use as a dependency in other projects locally
So the answer to your question is, it depends on whether you want it in installed into your local repo. Install will also run package because it's higher up in the goal phase stack.
This can now be done without expression trees and extension methods in a type safe manner with the new C# feature nameof()
like this:
Attribute.IsDefined(typeof(YourClass).GetProperty(nameof(YourClass.Id)), typeof(IsIdentity));
nameof() was introduced in C# 6
Take note, with full paths the line: [MethodImpl(MethodImplOptions.Synchronized)]
should look like
[System.Runtime.CompilerServices.MethodImpl(System.Runtime.CompilerServices.MethodImplOptions.Synchronized)]

Agree with previous answers.
A little correction: There's a better way to print the decimal digits from left to right, without allocating extra buffer. In addition you may want to display a zero characeter if the score
is 0 (the loop suggested in the previous answers won't print anythng).
This demands an additional pass:
int div;
for (div = 1; div <= score; div *= 10)
;
do
{
div /= 10;
printf("%d\n", score / div);
score %= div;
} while (score);
Following yet again on the use of a custom aggregate function of string concatenation: you need to remember that the select statement will place rows in any order, so you will need to do a sub select in the from statement with an order by clause, and then an outer select with a group by clause to aggregate the strings, thus:
SELECT custom_aggregate(MY.special_strings)
FROM (SELECT special_strings, grouping_column
FROM a_table
ORDER BY ordering_column) MY
GROUP BY MY.grouping_column
There are lots of differences between ISO 8601 and RFC 3339. Here is some examples to give you an idea:
2020-12-09T16:09:53+00:00
is a date time value that is compliant both both standards.
2020-12-09 16:09:53+00:00
uses a space to separate the date and time. This is allowed by RFC 3339 but not allowed by ISO 8601.
2020-12-09T16:09:53-00:00
has a negative sign in the time offset. This is allowed by RFC 3339 but not allowed by ISO 8601.
20201209T160953Z
omits the hyphens. This is allowed by ISO 8601 but not allowed by RFC 3339.
ISO 8601 allows for things like ordinal dates such as 2020-344
which represents the 344th day of year 2020. RFC 3339 doesn't allow for that.
For your questions:
Is one just an extension?
No. As shown above each standard supports syntax variations not supported by the the other standard. So one syntax is not a superset or an extension of the other.
Should I use one over the other?
Of course this depends on your scenario. A safe general strategy is to generate date time strings that are valid by both standards.
Another good general strategy is to use an existing standard library for parsing/formatting date time strings and not write custom implementations unless you are addressing a genuinely custom scenario.
Do I really need to care that bad?
Well, that's up to you. Most regular developers who deal with date time strings should have a high level understanding but don't need to dive into the details.
For me the answer was to cd into the root directory of the app before running heroku create
or git push heroku master
I personnally went for:
set wrap
,set linebreak
set breakindent
set showbreak=?
.Some explanation:
wrap
option visually wraps line instead of having to scroll horizontallylinebreak
is for wrapping long lines at a specific character instead of just anywhere when the line happens to be too long, like in the middle of a word. By default, it breaks on whitespace (word separator), but you can configure it with breakat
. It also does NOT insert EOL
in the file as the OP wanted.breakat
is the character where it will visually break the line. No need to modify it if you want to break at whitespace between two words.breakindent
enables to visually indent the line when it breaks.showbreak
enables to set the character which indicates this break.See :h <keyword>
within vim for more info.
Note that you don't need to modify textwidth
nor wrapmargin
if you go this route.
Try using this query:
SELECT name, COUNT(*) value_count FROM company_master GROUP BY name HAVING value_count > 1;

The following is not exactly the same but similar, I was searching for a snippet to add a call to the interface method, but found this question, so I decided to add this snippet for those who were searching for it like me and found this question:
public class MyClass
{
//... class code goes here
public interface DataLoadFinishedListener {
public void onDataLoadFinishedListener(int data_type);
}
private DataLoadFinishedListener m_lDataLoadFinished;
public void setDataLoadFinishedListener(DataLoadFinishedListener dlf){
this.m_lDataLoadFinished = dlf;
}
private void someOtherMethodOfMyClass()
{
m_lDataLoadFinished.onDataLoadFinishedListener(1);
}
}
Usage is as follows:
myClassObj.setDataLoadFinishedListener(new MyClass.DataLoadFinishedListener() {
@Override
public void onDataLoadFinishedListener(int data_type) {
}
});
It allows for further querying further down the line. If this was beyond a service boundary say, then the user of this IQueryable object would be allowed to do more with it.
For instance if you were using lazy loading with nhibernate this might result in graph being loaded when/if needed.
For anything related to the internet, your app must have the internet permission in ManifestFile. I solved this issue by adding permission in AndroidManifest.xml

git stash apply
Just check out the branch you want your changes on, and then git stash apply
. Then use git diff
to see the result.
After you're all done with your changes—the apply
looks good and you're sure you don't need the stash any more—then use git stash drop
to get rid of it.
I always suggest using git stash apply
rather than git stash pop
. The difference is that apply
leaves the stash around for easy re-try of the apply
, or for looking at, etc. If pop
is able to extract the stash, it will immediately also drop
it, and if you the suddenly realize that you wanted to extract it somewhere else (in a different branch), or with --index
, or some such, that's not so easy. If you apply
, you get to choose when to drop
.
It's all pretty minor one way or the other though, and for a newbie to git, it should be about the same. (And you can skip all the rest of this!)
There are at least three or four different "ways to use git stash", as it were. The above is for "way 1", the "easy way":
You started with a clean branch, were working on some changes, and then realized you were doing them in the wrong branch. You just want to take the changes you have now and "move" them to another branch.
This is the easy case, described above. Run git stash save
(or plain git stash
, same thing). Check out the other branch and use git stash apply
. This gets git to merge in your earlier changes, using git's rather powerful merge mechanism. Inspect the results carefully (with git diff
) to see if you like them, and if you do, use git stash drop
to drop the stash. You're done!
You started some changes and stashed them. Then you switched to another branch and started more changes, forgetting that you had the stashed ones.
Now you want to keep, or even move, these changes, and apply your stash too.
You can in fact git stash save
again, as git stash
makes a "stack" of changes. If you do that you have two stashes, one just called stash
—but you can also write stash@{0}
—and one spelled stash@{1}
. Use git stash list
(at any time) to see them all. The newest is always the lowest-numbered. When you git stash drop
, it drops the newest, and the one that was stash@{1}
moves to the top of the stack. If you had even more, the one that was stash@{2}
becomes stash@{1}
, and so on.
You can apply
and then drop
a specific stash, too: git stash apply stash@{2}
, and so on. Dropping a specific stash, renumbers only the higher-numbered ones. Again, the one without a number is also stash@{0}
.
If you pile up a lot of stashes, it can get fairly messy (was the stash I wanted stash@{7}
or was it stash@{4}
? Wait, I just pushed another, now they're 8 and 5?). I personally prefer to transfer these changes to a new branch, because branches have names, and cleanup-attempt-in-December
means a lot more to me than stash@{12}
. (The git stash
command takes an optional save-message, and those can help, but somehow, all my stashes just wind up named WIP on branch
.)
(Extra-advanced) You've used git stash save -p
, or carefully git add
-ed and/or git rm
-ed specific bits of your code before running git stash save
. You had one version in the stashed index/staging area, and another (different) version in the working tree. You want to preserve all this. So now you use git stash apply --index
, and that sometimes fails with:
Conflicts in index. Try without --index.
You're using git stash save --keep-index
in order to test "what will be committed". This one is beyond the scope of this answer; see this other StackOverflow answer instead.
For complicated cases, I recommend starting in a "clean" working directory first, by committing any changes you have now (on a new branch if you like). That way the "somewhere" that you are applying them, has nothing else in it, and you'll just be trying the stashed changes:
git status # see if there's anything you need to commit
# uh oh, there is - let's put it on a new temp branch
git checkout -b temp # create new temp branch to save stuff
git add ... # add (and/or remove) stuff as needed
git commit # save first set of changes
Now you're on a "clean" starting point. Or maybe it goes more like this:
git status # see if there's anything you need to commit
# status says "nothing to commit"
git checkout -b temp # optional: create new branch for "apply"
git stash apply # apply stashed changes; see below about --index
The main thing to remember is that the "stash" is a commit, it's just a slightly "funny/weird" commit that's not "on a branch". The apply
operation looks at what the commit changed, and tries to repeat it wherever you are now. The stash will still be there (apply
keeps it around), so you can look at it more, or decide this was the wrong place to apply
it and try again differently, or whatever.
Any time you have a stash, you can use git stash show -p
to see a simplified version of what's in the stash. (This simplified version looks only at the "final work tree" changes, not the saved index changes that --index
restores separately.) The command git stash apply
, without --index
, just tries to make those same changes in your work-directory now.
This is true even if you already have some changes. The apply
command is happy to apply a stash to a modified working directory (or at least, to try to apply it). You can, for instance, do this:
git stash apply stash # apply top of stash stack
git stash apply stash@{1} # and mix in next stash stack entry too
You can choose the "apply" order here, picking out particular stashes to apply in a particular sequence. Note, however, that each time you're basically doing a "git merge", and as the merge documentation warns:
Running git merge with non-trivial uncommitted changes is discouraged: while possible, it may leave you in a state that is hard to back out of in the case of a conflict.
If you start with a clean directory and are just doing several git apply
operations, it's easy to back out: use git reset --hard
to get back to the clean state, and change your apply
operations. (That's why I recommend starting in a clean working directory first, for these complicated cases.)
Let's say you're doing Lots Of Advanced Git Stuff, and you've made a stash, and want to git stash apply --index
, but it's no longer possible to apply the saved stash with --index
, because the branch has diverged too much since the time you saved it.
This is what git stash branch
is for.
If you:
stash
, thengit stash apply --index
the attempt to re-create the changes definitely will work. This is what git stash branch newbranch
does. (And it then drops the stash since it was successfully applied.)
--index
(what the heck is it?)What the --index
does is simple to explain, but a bit complicated internally:
git add
(or "stage") them before commit
ing.git stash
, you might have edited both files foo
and zorg
, but only staged one of those.git add
s the add
ed things and does not git add
the non-added things. That is, if you add
ed foo
but not zorg
back before you did the stash
, it might be nice to have that exact same setup. What was staged, should again be staged; what was modified but not staged, should again be modified but not staged.The --index
flag to apply
tries to set things up this way. If your work-tree is clean, this usually just works. If your work-tree already has stuff add
ed, though, you can see how there might be some problems here. If you leave out --index
, the apply
operation does not attempt to preserve the whole staged/unstaged setup. Instead, it just invokes git's merge machinery, using the work-tree commit in the "stash bag". If you don't care about preserving staged/unstaged, leaving out --index
makes it a lot easier for git stash apply
to do its thing.
Cause
A container with the same name is still existing.
Solution
To reuse the same container name, delete the existing container by:
docker rm <container name>
Explanation
Containers can exist in following states, during which the container name can't be used for another container:
created
restarting
running
paused
exited
dead
You can see containers in running
state by using :
docker ps
To show containers in all states and find out if a container name is taken, use:
docker ps -a
Suppose your query is "select id,name from users where rollNo = 1001".
Here query will return a object with id and name column. Your Response class is like bellow:
public class UserObject{
int id;
String name;
String rollNo;
public UserObject(Object[] columns) {
this.id = (columns[0] != null)?((BigDecimal)columns[0]).intValue():0;
this.name = (String) columns[1];
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getRollNo() {
return rollNo;
}
public void setRollNo(String rollNo) {
this.rollNo = rollNo;
}
}
here UserObject
constructor will get a Object Array and set data with object.
public UserObject(Object[] columns) {
this.id = (columns[0] != null)?((BigDecimal)columns[0]).intValue():0;
this.name = (String) columns[1];
}
Your query executing function is like bellow :
public UserObject getUserByRoll(EntityManager entityManager,String rollNo) {
String queryStr = "select id,name from users where rollNo = ?1";
try {
Query query = entityManager.createNativeQuery(queryStr);
query.setParameter(1, rollNo);
return new UserObject((Object[]) query.getSingleResult());
} catch (Exception e) {
e.printStackTrace();
throw e;
}
}
Here you have to import bellow packages:
import javax.persistence.Query;
import javax.persistence.EntityManager;
Now your main class, you have to call this function.
First you have to get EntityManager and call this getUserByRoll(EntityManager entityManager,String rollNo)
function. Calling procedure is given bellow:
@PersistenceContext
private EntityManager entityManager;
UserObject userObject = getUserByRoll(entityManager,"1001");
Now you have data in this userObject.
Here is Imports
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
Note:
query.getSingleResult() return a array. You have to maintain the column position and data type.
select id,name from users where rollNo = ?1
query return a array and it's [0] --> id and [1] -> name
.

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin
not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors
at your server side.
You can fetch request using mode: 'cors'
. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.
So in both condition you need to configure cors
in your server or you need to use custom proxy server.
If you know the total length of the string that you're going to preallocate then the most efficient way to concatenate strings may be using the builtin function copy
. If you don't know the total length before hand, do not use copy
, and read the other answers instead.
In my tests, that approach is ~3x faster than using bytes.Buffer
and much much faster (~12,000x) than using the operator +
. Also, it uses less memory.
I've created a test case to prove this and here are the results:
BenchmarkConcat 1000000 64497 ns/op 502018 B/op 0 allocs/op
BenchmarkBuffer 100000000 15.5 ns/op 2 B/op 0 allocs/op
BenchmarkCopy 500000000 5.39 ns/op 0 B/op 0 allocs/op
Below is code for testing:
package main
import (
"bytes"
"strings"
"testing"
)
func BenchmarkConcat(b *testing.B) {
var str string
for n := 0; n < b.N; n++ {
str += "x"
}
b.StopTimer()
if s := strings.Repeat("x", b.N); str != s {
b.Errorf("unexpected result; got=%s, want=%s", str, s)
}
}
func BenchmarkBuffer(b *testing.B) {
var buffer bytes.Buffer
for n := 0; n < b.N; n++ {
buffer.WriteString("x")
}
b.StopTimer()
if s := strings.Repeat("x", b.N); buffer.String() != s {
b.Errorf("unexpected result; got=%s, want=%s", buffer.String(), s)
}
}
func BenchmarkCopy(b *testing.B) {
bs := make([]byte, b.N)
bl := 0
b.ResetTimer()
for n := 0; n < b.N; n++ {
bl += copy(bs[bl:], "x")
}
b.StopTimer()
if s := strings.Repeat("x", b.N); string(bs) != s {
b.Errorf("unexpected result; got=%s, want=%s", string(bs), s)
}
}
// Go 1.10
func BenchmarkStringBuilder(b *testing.B) {
var strBuilder strings.Builder
b.ResetTimer()
for n := 0; n < b.N; n++ {
strBuilder.WriteString("x")
}
b.StopTimer()
if s := strings.Repeat("x", b.N); strBuilder.String() != s {
b.Errorf("unexpected result; got=%s, want=%s", strBuilder.String(), s)
}
}
In addition to Sabeen's answer:
The first column id is your primary key.
Don't insert ''
into the primary key, but insert null instead.
INSERT INTO users
(`id`,`title`,`firstname`,`lastname`,`company`,`address`,`city`,`county`
,`postcode`,`phone`,`mobile`,`category`,`email`,`password`,`userlevel`)
VALUES
(null,'','John','Doe','company','Streeet','city','county'
,'postcode','phone','','category','[email protected]','','');
If it's an autoincrement key this will fix your problem.
If not make id
an autoincrement key, and always insert null
into it to trigger an autoincrement.
MySQL has a setting to autoincrement keys only on null
insert or on both inserts of 0
and null
. Don't count on this setting, because your code may break if you change server.
If you insert null
your code will always work.
See: http://dev.mysql.com/doc/refman/5.0/en/example-auto-increment.html

Convert Date to String using this function
public String convertDateToString(Date date, String format) {
String dateStr = null;
DateFormat df = new SimpleDateFormat(format);
try {
dateStr = df.format(date);
} catch (Exception ex) {
System.out.println(ex);
}
return dateStr;
}
From Convert Date to String in Java . And convert string to date again
public Date convertStringToDate(String dateStr, String format) {
Date date = null;
DateFormat df = new SimpleDateFormat(format);
try {
date = df.parse(dateStr);
} catch (Exception ex) {
System.out.println(ex);
}
return date;
}
TL;DR ...and late to the party, but that short explanation might help future googlers..
In general that error message means that the replacement doesn't fit into the corresponding column of the dataframe.
A minimal example:
df <- data.frame(a = 1:2); df$a <- 1:3
throws the error
Error in
$<-.data.frame
(*tmp*
, a, value = 1:3) : replacement has 3 rows, data has 2
which is clear, because the vector a
of df
has 2 entries (rows) whilst the vector we try to replace it has 3 entries (rows).
select *
from Table1 as t1
where
exists (
select *
from Table1 as t2
where t2.Phone = t1.Phone and t2.id <> t1.id
)
I always use method 2 as well. The only benefit of using each is if you're just reading (rather than re-assigning) the value of the hash entry, you're not constantly de-referencing the hash.
Easiest method: Alt
+Enter
on
private static final long serialVersionUID = ;
IntelliJ will underline the space after the =
. put your cursor on it and hit alt
+Enter
(Option
+Enter
on Mac). You'll get a popover that says "Randomly Change serialVersionUID Initializer". Just hit enter, and it'll populate that space with a random long.
The bootstrap 3 documentation lists this under helper classes:
Muted
, Primary
, Success
, Info
, Warning
, Danger
.
The bootstrap 4 documentation lists this under utilities -> color, and has more options:
primary
, secondary
, success
, danger
, warning
, info
, light
, dark
, muted
, white
.
To access them one uses the class
text-[class-name]
So, if I want the primary text color for example I would do something like this:
<p class="text-primary">This text is the primary color.</p>
This is not a huge number of choices, but it's some.
In addition to @stenix, this worked perfectly to me
url = window.location.href;
paramName = 'myparam';
paramValue = $(this).val();
var pattern = new RegExp('('+paramName+'=).*?(&|$)')
var newUrl = url.replace(pattern,'$1' + paramValue + '$2');
var n=url.indexOf(paramName);
alert(n)
if(n == -1){
newUrl = newUrl + (newUrl.indexOf('?')>0 ? '&' : '?') + paramName + '=' + paramValue
}
window.location.href = newUrl;
Here no need to save the "url" variable, just replace in current url
If you plan to get first element often - you can extend QuerySet in this direction:
class FirstQuerySet(models.query.QuerySet):
def first(self):
return self[0]
class ManagerWithFirstQuery(models.Manager):
def get_query_set(self):
return FirstQuerySet(self.model)
Define model like this:
class MyModel(models.Model):
objects = ManagerWithFirstQuery()
And use it like this:
first_object = MyModel.objects.filter(x=100).first()
Go to the Team Explorer tab then click Branches. In the branches select your branch from remotes/origin. For example, you want to reset your master branch. Right-click at the master branch in remotes/origin then select Reset then click Delete changes. This will reset your local branch and removes all locally committed changes.
In the recent go versions from 1.14 onwards, we have to do go mod vendor
before building or running, since by default go appends -mod=vendor
to the go commands.
So after doing go mod vendor
, if we try to build, we won't face this issue.
In Swift3:
let fileUrl = Foundation.URL(string: filePath)
It also posible string replacement with stringByReplacingCharactersInRange:withString:
for (int i = 0; i < card.length - 4; i++) {
if (![[card substringWithRange:NSMakeRange(i, 1)] isEqual:@" "]) {
NSRange range = NSMakeRange(i, 1);
card = [card stringByReplacingCharactersInRange:range withString:@"*"];
}
} //out: **** **** **** 1234
Note that you can change the default encoding of the JVM using the confusingly-named property file.encoding
.
If your application is particularly sensitive to encodings (perhaps through usage of APIs implying default encodings), then you should explicitly set this on JVM startup to a consistent (known) value.
Try deleting the .jenkins folder from your system which is located ate the below path. C:\Users\"Your PC Name".jenkins
Now download a fresh and a stable version of .war file from official website of jenkins. For eg. 2.1 and follow the steps to install.
The smallest piece of code would be:
public List<Integer> myWork(int[] array) {
return Arrays.asList(ArrayUtils.toObject(array));
}
where ArrayUtils comes from commons-lang :)
Here, this ones working. :)

forget all the answers, this line of CSS worked for me in 2 seconds :
height:100vh;
1vh
= 1% of browser screen height
For responsive layout scaling, you might want to use :
min-height: 100vh
[update november 2018] As mentionned in the comments, using the min-height might avoid having issues on reponsive designs
[update april 2018] As mentioned in the comments, back in 2011 when the question was asked, not all browsers supported the viewport units.
The other answers were the solutions back then -- vmax
is still not supported in IE, so this might not be the best solution for all yet.
For those looking to use axios-mock-adapter in place of the mockfetch example in the Redux documentation for async testing, I successfully used the following:
describe('SignInUser', () => {
var history = {
push: function(str) {
expect(str).toEqual('/feed');
}
}
it('Dispatches authorization', () => {
let mock = new MockAdapter(axios);
mock.onPost(`${ROOT_URL}/auth/signin`, {
email: '[email protected]',
password: 'test'
}).reply(200, {token: 'testToken' });
const expectedActions = [ { type: types.AUTH_USER } ];
const store = mockStore({ auth: [] });
return store.dispatch(actions.signInUser({
email: '[email protected]',
password: 'test',
}, history)).then(() => {
expect(store.getActions()).toEqual(expectedActions);
});
});
In order to test a successful case for signInUser
in file actions/index.js:
export const signInUser = ({ email, password }, history) => async dispatch => {
const res = await axios.post(`${ROOT_URL}/auth/signin`, { email, password })
.catch(({ response: { data } }) => {
...
});
if (res) {
dispatch({ type: AUTH_USER }); // Test verified this
localStorage.setItem('token', res.data.token); // Test mocked this
history.push('/feed'); // Test mocked this
}
}
Given that this is being done with jest, the localstorage call had to be mocked. This was in file src/setupTests.js:
const localStorageMock = {
removeItem: jest.fn(),
getItem: jest.fn(),
setItem: jest.fn(),
clear: jest.fn()
};
global.localStorage = localStorageMock;
Put this in your CSS:
white-space:nowrap;
Get more information here: http://www.w3.org/wiki/CSS/Properties/white-space
white-space
The white-space
property declares how white space inside the element is handled.
Values
normal
This value directs user agents to collapse sequences of white space, and break lines as necessary to fill line boxes.
pre
This value prevents user agents from collapsing sequences of white space. Lines are only broken at newlines in the source, or at occurrences of "\A" in generated content.
nowrap
This value collapses white space as for 'normal', but suppresses line breaks within text.
pre-wrap
This value prevents user agents from collapsing sequences of white space. Lines are broken at newlines in the source, at occurrences of "\A" in generated content, and as necessary to fill line boxes.
pre-line
This value directs user agents to collapse sequences of white space. Lines are broken at newlines in the source, at occurrences of "\A" in generated content, and as necessary to fill line boxes.
inherit
Takes the same specified value as the property for the element's parent.
An ALTER TABLE
statement adding the PRIMARY KEY
column works correctly in my testing:
ALTER TABLE tbl ADD id INT PRIMARY KEY AUTO_INCREMENT;
On a temporary table created for testing purposes, the above statement created the AUTO_INCREMENT
id
column and inserted auto-increment values for each existing row in the table, starting with 1.
You get this error when the function isn't on the MATLAB path or in pwd.
First, make sure that you are able to find the function using:
>> which divrat
c:\work\divrat\divrat.m
If it returns:
>> which divrat
'divrat' not found.
It is not on the MATLAB path or in PWD.
Second, make sure that the directory that contains divrat
is on the MATLAB path using the PATH
command. It may be that a directory that you thought was on the path isn't actually on the path.
Finally, make sure you aren't using a "private" directory. If divrat
is in a directory named private, it will be accessible by functions in the parent directory, but not from the MATLAB command line:
>> foo
ans =
1
>> divrat(1,1)
??? Undefined function or method 'divrat' for input arguments of type 'double'.
>> which -all divrat
c:\work\divrat\private\divrat.m % Private to divrat
I = imread('peppers.png');
H = fspecial('average', [5 5]);
I = imfilter(I, H);
imshow(I)
Note that filters can be applied to intensity images (2D matrices) using filter2
, while on multi-dimensional images (RGB images or 3D matrices) imfilter
is used.
Also on Intel processors, imfilter
can use the Intel Integrated Performance Primitives (IPP) library to accelerate execution.
Every example here shows a solution using the FileReader. It is convenient if you do not need to care about a file encoding. If you use some other languages than english, encoding is quite important. Imagine you have file with this text
Príliš žlutoucký kun
úpel dábelské ódy
and the file uses windows-1250 format. If you use FileReader you will get this result:
P??li? ?lu?ou?k? k??
?p?l ??belsk? ?dy
So in this case you would need to specify encoding as Cp1250 (Windows Eastern European) but the FileReader doesn't allow you to do so. In this case you should use InputStreamReader on a FileInputStream.
Example:
String encoding = "Cp1250";
File file = new File("foo.txt");
if (file.exists()) {
try (BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file), encoding))) {
String line = null;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
} catch (IOException e) {
e.printStackTrace();
}
}
else {
System.out.println("file doesn't exist");
}
In case you want to read the file character after character do not use BufferedReader.
try (InputStreamReader isr = new InputStreamReader(new FileInputStream(file), encoding)) {
int data = isr.read();
while (data != -1) {
System.out.print((char) data);
data = isr.read();
}
} catch (IOException e) {
e.printStackTrace();
}
Perhaps something akin to:
bool is_empty(std::ifstream& pFile)
{
return pFile.peek() == std::ifstream::traits_type::eof();
}
Short and sweet.
With concerns to your error, the other answers use C-style file access, where you get a FILE*
with specific functions.
Contrarily, you and I are working with C++ streams, and as such cannot use those functions. The above code works in a simple manner: peek()
will peek at the stream and return, without removing, the next character. If it reaches the end of file, it returns eof()
. Ergo, we just peek()
at the stream and see if it's eof()
, since an empty file has nothing to peek at.
Note, this also returns true if the file never opened in the first place, which should work in your case. If you don't want that:
std::ifstream file("filename");
if (!file)
{
// file is not open
}
if (is_empty(file))
{
// file is empty
}
// file is open and not empty
As shown on Removing standard server headers on Windows Azure Web Sites page, you can remove headers with the following:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<clear />
</customHeaders>
</httpProtocol>
<security>
<requestFiltering removeServerHeader="true"/>
</security>
</system.webServer>
<system.web>
<httpRuntime enableVersionHeader="false" />
</system.web>
</configuration>
This removes the Server header, and the X- headers.
This worked locally in my tests in Visual Studio 2015.

I've found the very simple answer: isAdded()
:
Return
true
if the fragment is currently added to its activity.
@Override
protected void onPostExecute(Void result){
if(isAdded()){
getResources().getString(R.string.app_name);
}
}
To avoid onPostExecute
from being called when the Fragment
is not attached to the Activity
is to cancel the AsyncTask
when pausing or stopping the Fragment
. Then isAdded()
would not be necessary anymore. However, it is advisable to keep this check in place.
To check for all int chars, you can simply use a double negative. if (!searchString.matches("[^0-9]+$")) ...
[^0-9]+$ checks to see if there are any characters that are not integer, so the test fails if it's true. Just NOT that and you get true on success.
None of the previous answers quite got to the bottom of my own confusion, so I'd like to add my own.
What I was missing is that lea
operations treat the use of parentheses different than how mov
does.
Think of C. Let's say I have an array of long
that I call array
. Now the expression array[i]
performs a dereference, loading the value from memory at the address array + i * sizeof(long)
[1].
On the other hand, consider the expression &array[i]
. This still contains the sub-expression array[i]
, but no dereferencing is performed! The meaning of array[i]
has changed. It no longer means to perform a deference but instead acts as a kind of a specification, telling &
what memory address we're looking for. If you like, you could alternatively think of the &
as "cancelling out" the dereference.
Because the two use-cases are similar in many ways, they share the syntax array[i]
, but the existence or absence of a &
changes how that syntax is interpreted. Without &
, it's a dereference and actually reads from the array. With &
, it's not. The value array + i * sizeof(long)
is still calculated, but it is not dereferenced.
The situation is very similar with mov
and lea
. With mov
, a dereference occurs that does not happen with lea
. This is despite the use of parentheses that occurs in both. For instance, movq (%r8), %r9
and leaq (%r8), %r9
. With mov
, these parentheses mean "dereference"; with lea
, they don't. This is similar to how array[i]
only means "dereference" when there is no &
.
An example is in order.
Consider the code
movq (%rdi, %rsi, 8), %rbp
This loads the value at the memory location %rdi + %rsi * 8
into the register %rbp
. That is: get the value in the register %rdi
and the value in the register %rsi
. Multiply the latter by 8, and then add it to the former. Find the value at this location and place it into the register %rbp
.
This code corresponds to the C line x = array[i];
, where array
becomes %rdi
and i
becomes %rsi
and x
becomes %rbp
. The 8
is the length of the data type contained in the array.
Now consider similar code that uses lea
:
leaq (%rdi, %rsi, 8), %rbp
Just as the use of movq
corresponded to dereferencing, the use of leaq
here corresponds to not dereferencing. This line of assembly corresponds to the C line x = &array[i];
. Recall that &
changes the meaning of array[i]
from dereferencing to simply specifying a location. Likewise, the use of leaq
changes the meaning of (%rdi, %rsi, 8)
from dereferencing to specifying a location.
The semantics of this line of code are as follows: get the value in the register %rdi
and the value in the register %rsi
. Multiply the latter by 8, and then add it to the former. Place this value into the register %rbp
. No load from memory is involved, just arithmetic operations [2].
Note that the only difference between my descriptions of leaq
and movq
is that movq
does a dereference, and leaq
doesn't. In fact, to write the leaq
description, I basically copy+pasted the description of movq
, and then removed "Find the value at this location".
To summarize: movq
vs. leaq
is tricky because they treat the use of parentheses, as in (%rsi)
and (%rdi, %rsi, 8)
, differently. In movq
(and all other instruction except lea
), these parentheses denote a genuine dereference, whereas in leaq
they do not and are purely convenient syntax.
[1] I've said that when array
is an array of long
, the expression array[i]
loads the value from the address array + i * sizeof(long)
. This is true, but there's a subtlety that should be addressed. If I write the C code
long x = array[5];
this is not the same as typing
long x = *(array + 5 * sizeof(long));
It seems that it should be based on my previous statements, but it's not.
What's going on is that C pointer addition has a trick to it. Say I have a pointer p
pointing to values of type T
. The expression p + i
does not mean "the position at p
plus i
bytes". Instead, the expression p + i
actually means "the position at p
plus i * sizeof(T)
bytes".
The convenience of this is that to get "the next value" we just have to write p + 1
instead of p + 1 * sizeof(T)
.
This means that the C code long x = array[5];
is actually equivalent to
long x = *(array + 5)
because C will automatically multiply the 5
by sizeof(long)
.
So in the context of this StackOverflow question, how is this all relevant? It means that when I say "the address array + i * sizeof(long)
", I do not mean for "array + i * sizeof(long)
" to be interpreted as a C expression. I am doing the multiplication by sizeof(long)
myself in order to make my answer more explicit, but understand that due to that, this expression should not be read as C. Just as normal math that uses C syntax.
[2] Side note: because all lea
does is arithmetic operations, its arguments don't actually have to refer to valid addresses. For this reason, it's often used to perform pure arithmetic on values that may not be intended to be dereferenced. For instance, cc
with -O2
optimization translates
long f(long x) {
return x * 5;
}
into the following (irrelevant lines removed):
f:
leaq (%rdi, %rdi, 4), %rax # set %rax to %rdi + %rdi * 4
ret
You should set z-index
to absolutely positioned div that is greater than to relative div.
Something like that
<div style="position: relative; width:600px; z-index: 10;">
<p>Content of unknown length</p>
<div>Content of unknown height</div>
<div class="btn" style="position: absolute; right: 0; bottom: 0; width: 200px; height: 100px; z-index: 20;"></div>
</div>
z-index
sets layers positioning in depth of page.
Or you may use floating to show all text of unkown length. But in this case you could not absolutely position your div
<div style="position: relative; width:600px;">
<div class="btn" style="float: right; width: 200px; height: 100px;"></div>
<p>Content of unknown length Content of unknown length Content of unknown length Content of unknown length Content of unknown length Content of unknown length Content of unknown length Content of unknown length</p>
<div>Content of unknown height</div>
<div class="btn" style="position: absolute; right: 0; bottom: 0; width: 200px; height: 100px;"></div>
</div>?
And to complement Rich's recursive answer, a non-recursive method.
Public Sub NonRecursiveMethod()
Dim fso, oFolder, oSubfolder, oFile, queue As Collection
Set fso = CreateObject("Scripting.FileSystemObject")
Set queue = New Collection
queue.Add fso.GetFolder("your folder path variable") 'obviously replace
Do While queue.Count > 0
Set oFolder = queue(1)
queue.Remove 1 'dequeue
'...insert any folder processing code here...
For Each oSubfolder In oFolder.SubFolders
queue.Add oSubfolder 'enqueue
Next oSubfolder
For Each oFile In oFolder.Files
'...insert any file processing code here...
Next oFile
Loop
End Sub
You can use a queue for FIFO behaviour (shown above), or you can use a stack for LIFO behaviour which would process in the same order as a recursive approach (replace Set oFolder = queue(1)
with Set oFolder = queue(queue.Count)
and replace queue.Remove(1)
with queue.Remove(queue.Count)
, and probably rename the variable...)

A quick understanding of how pip works pip

this should work, probably.

Really cheap solution:
urllib.urlopen('http://user:[email protected]/api')
(which you may decide is not suitable for a number of reasons, like security of the url)
>>> import urllib, json
>>> result = urllib.urlopen('https://personal-access-token:[email protected]/repos/:owner/:repo')
>>> r = json.load(result.fp)
>>> result.close()
the reason why $(string) is not working is because jquery is not finding html content between $(). Therefore you need to first parse it to html. once you have a variable in which you have parsed the html. you can then use $(string) and use all functions available on the object
According to the documentation, the static method UUID.randomUUID()
generates a type 4 UUID.
This means that six bits are used for some type information and the remaining 122 bits are assigned randomly.
The six non-random bits are distributed with four in the most significant half of the UUID and two in the least significant half. So the most significant half of your UUID contains 60 bits of randomness, which means you on average need to generate 2^30 UUIDs to get a collision (compared to 2^61 for the full UUID).
So I would say that you are rather safe. Note, however that this is absolutely not true for other types of UUIDs, as Carl Seleborg mentions.
Incidentally, you would be slightly better off by using the least significant half of the UUID (or just generating a random long using SecureRandom).
Here is code that will upload multiple images at once, into a specific folder!
The HTML:
<form method="post" enctype="multipart/form-data" id="image_upload_form" action="submit_image.php">
<input type="file" name="images" id="images" multiple accept="image/x-png, image/gif, image/jpeg, image/jpg" />
<button type="submit" id="btn">Upload Files!</button>
</form>
<div id="response"></div>
<ul id="image-list">
</ul>
The PHP:
<?php
$errors = $_FILES["images"]["error"];
foreach ($errors as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$name = $_FILES["images"]["name"][$key];
//$ext = pathinfo($name, PATHINFO_EXTENSION);
$name = explode("_", $name);
$imagename='';
foreach($name as $letter){
$imagename .= $letter;
}
move_uploaded_file( $_FILES["images"]["tmp_name"][$key], "images/uploads/" . $imagename);
}
}
echo "<h2>Successfully Uploaded Images</h2>";
And finally, the JavaSCript/Ajax:
(function () {
var input = document.getElementById("images"),
formdata = false;
function showUploadedItem (source) {
var list = document.getElementById("image-list"),
li = document.createElement("li"),
img = document.createElement("img");
img.src = source;
li.appendChild(img);
list.appendChild(li);
}
if (window.FormData) {
formdata = new FormData();
document.getElementById("btn").style.display = "none";
}
input.addEventListener("change", function (evt) {
document.getElementById("response").innerHTML = "Uploading . . ."
var i = 0, len = this.files.length, img, reader, file;
for ( ; i < len; i++ ) {
file = this.files[i];
if (!!file.type.match(/image.*/)) {
if ( window.FileReader ) {
reader = new FileReader();
reader.onloadend = function (e) {
showUploadedItem(e.target.result, file.fileName);
};
reader.readAsDataURL(file);
}
if (formdata) {
formdata.append("images[]", file);
}
}
}
if (formdata) {
$.ajax({
url: "submit_image.php",
type: "POST",
data: formdata,
processData: false,
contentType: false,
success: function (res) {
document.getElementById("response").innerHTML = res;
}
});
}
}, false);
}());
Hope this helps
Good references to the docs. Here's how you can guarantee the order regardless of the documentation / implementation:
k, v = zip(*d.iteritems())
The "obvious" way (for most people)
theBoolean = !theBoolean;
The "shortest" way (most of the time)
theBoolean ^= true;
The "most visual" way (most uncertainly)
theBoolean = theBoolean ? false : true;
theMethod( theBoolean ^= true );
Since the assignment operator always returns what has been assigned, this will toggle the value via the bitwise operator, and then return the newly assigned value to be used in the method call.
To run tests with node/npm without installing Mocha globally, you can do this:
• Install Mocha locally to your project (npm install mocha --save-dev
)
• Optionally install an assertion library (npm install chai --save-dev
)
• In your package.json
, add a section for scripts
and target the mocha binary
"scripts": {
"test": "node ./node_modules/mocha/bin/mocha"
}
• Put your spec files in a directory named /test
in your root directory
• In your spec files, import the assertion library
var expect = require('chai').expect;
• You don't need to import mocha, run mocha.setup
, or call mocha.run()
• Then run the script from your project root:
npm test
I've written a function that will reload the page without post submission and it will work with hashes, too.
I do this by adding / modifying a GET parameter in the URL called reload
by updating its value with the current timestamp in ms.
var reload = function () {
var regex = new RegExp("([?;&])reload[^&;]*[;&]?");
var query = window.location.href.split('#')[0].replace(regex, "$1").replace(/&$/, '');
window.location.href =
(window.location.href.indexOf('?') < 0 ? "?" : query + (query.slice(-1) != "?" ? "&" : ""))
+ "reload=" + new Date().getTime() + window.location.hash;
};
Keep in mind, if you want to trigger this function in a href attribute, implement it this way: href="javascript:reload();void 0;"
to make it work, successfully.
The downside of my solution is it will change the URL, so this "reload" is not a real reload, instead it's a load with a different query. Still, it could fit your needs like it does for me.

This is explained in the official Bootstrap 3 release docs:
Steps to disable responsive views
To disable responsive features, follow these steps. See it in action in the modified template below.
- Remove (or just don't add) the viewport
<meta>
mentioned in the CSS docs- Remove the max-width on the .container for all grid tiers with max-width: none !important; and set a regular width like width: 970px;. Be sure that this comes after the default Bootstrap CSS. You can optionally avoid the !important with media queries or some selector-fu.
- If using navbars, undo all the navbar collapsing and expanding behavior (this is too much to show here, so peep the example).
- For grid layouts, make use of .col-xs-* classes in addition to or in place of the medium/large ones. Don't worry, the extra-small device grid scales up to all resolutions, so you're set there.
You'll still need Respond.js for IE8 (since our media queries are still there and need to be picked up). This just disables the "mobile site" of Bootstrap.
See also the example on GetBootstrap.com/examples/non-responsive/
The VCS files can have its information coded in Quoted printable which is a nightmare. The above solution recommending "VCS to ICS Calendar Converter" is the way to go.

While doing my own server side JS experimentation I ended up using teajs. It conforms to common.js, is based on V8 AND is the only project that I know of that provides 'mod_teajs' apache server module.
In my opinion Node.js server is not production ready and lacks too many features - Apache is battle tested and the right way to do SSJS.
Your way can't work for two reasons.
You need to use set /p text=
for setting the variable with user input.
The other problem is the pipe.
A pipe starts two asynchronous cmd.exe instances and after finishing the job both instances are closed.
That's the cause why it seems that the variables are not set, but a small example shows that they are set but the result is lost later.
set myVar=origin
echo Hello | (set /p myVar= & set myVar)
set myVar
Outputs
Hello
origin
Alternatives: You can use the FOR loop to get values into variables or also temp files.
for /f "delims=" %%A in ('echo hello') do set "var=%%A"
echo %var%
or
>output.tmp echo Hello
>>output.tmp echo world
<output.tmp (
set /p line1=
set /p line2=
)
echo %line1%
echo %line2%
Alternative with a macro:
You can use a batch macro, this is a bit like the bash equivalent
@echo off
REM *** Get version string
%$set% versionString="ver"
echo The version is %versionString[0]%
REM *** Get all drive letters
`%$set% driveLetters="wmic logicaldisk get name /value | findstr "Name""
call :ShowVariable driveLetters
The definition of the macro can be found at
SO:Assign output of a program to a variable using a MS batch file
The answer shared by Paul is the best one. To expand more,
There can be only one default export per file. Whereas there can be more than one const exports. The default variable can be imported with any name, whereas const variable can be imported with it's particular name.
var message2 = 'I am exported';
export default message2;
export const message = 'I am also exported'
At the imports side we need to import it like this:
import { message } from './test';
or
import message from './test';
With the first import, the const variable is imported whereas, with the second one, the default one will be imported.
you can use nvidia-smi pmon -i 0

including compute mode, sm usage, memory usage, encoder usage, decoder usage.
Use the error
handler like this:
$('#image_id').error(function() {
alert('Image does not exist !!');
});
If the image cannot be loaded (for example, because it is not present at the supplied URL), the alert is displayed:
Update:
I think using:
$.ajax({url:'somefile.dat',type:'HEAD',error:do_something});
would be enough to check for a 404.
More Readings:
Update 2:
Your code should be like this:
$(this).error(function() {
alert('Image does not exist !!');
});
No need for these lines and that won't check if the remote file exists anyway:
var imgcheck = imgsrc.width;
if (imgcheck==0) {
alert("You have a zero size image");
} else {
//execute the rest of code here
}
Here's my salt :
current = datetime.datetime(mydate.year, mydate.month, 1)
next_month = datetime.datetime(mydate.year + int(mydate.month / 12), ((mydate.month % 12) + 1), 1)
Quick and easy :)
If you find yourself unable to catch errors with any of the solutions provided here, it may be that the server isn't handling CORS requests.
In that event, Javascript, much less Angular, can access the error information.
Look for warnings in your console that include CORB
or Cross-Origin Read Blocking
.
Also, the syntax has changed for handling errors (as described in every other answer). You now use pipe-able operators, like so:
this.service.requestsMyInfo(payload).pipe(
catcheError(err => {
// handle the error here.
})
);
Use a Java to C# translator on the Java implementation (java.util.PriorityQueue) in the Java Collections framework, or more intelligently use the algorithm and core code and plug it into a C# class of your own making that adheres to the C# Collections framework API for Queues, or at least Collections.
In Visual Studio, you can't just open a .cpp
file and expect it to run. You must create a project first, or open the .cpp in some existing project.
In your case, there is no project, so there is no project to build.
Go to File --> New --> Project --> Visual C++ --> Win32 Console Application
. You can uncheck "create a directory for solution". On the next page, be sure to check "Empty project".
Then, You can add .cpp
files you created outside the Visual Studio by right clicking in the Solution explorer
on folder icon "Source" and Add->Existing Item.
Obviously You can create new .cpp this way too (Add --> New). The .cpp file will be created in your project directory.
Then you can press ctrl+F5 to compile without debugging and can see output on console window.
You should use as_json
method which converts ActiveRecord objects to Ruby Hashes despite its name
tasks_records = TaskStoreStatus.all
tasks_records = tasks_records.as_json
# You can now add new records and return the result as json by calling `to_json`
tasks_records << TaskStoreStatus.last.as_json
tasks_records << { :task_id => 10, :store_name => "Koramanagala", :store_region => "India" }
tasks_records.to_json
You can also convert any ActiveRecord objects to a Hash with serializable_hash
and you can convert any ActiveRecord results to an Array with to_a
, so for your example :
tasks_records = TaskStoreStatus.all
tasks_records.to_a.map(&:serializable_hash)
And if you want an ugly solution for Rails prior to v2.3
JSON.parse(tasks_records.to_json) # please don't do it
How do I select multiple columns by labels in pandas?
Multiple label-based range slicing is not easily supported with pandas, but position-based slicing is, so let's try that instead:

Note that the +1
is added because when using iloc
the rightmost index is exclusive.
filter
is a nice and simple method for OP's headers, but this might not generalise well to arbitrary column names.
The "location-based" solution with loc
is a little closer to the ideal, but you cannot avoid creating intermediate DataFrames (that are eventually thrown out and garbage collected) to compute the final result range -- something that we would ideally like to avoid.
Lastly, "pick your columns directly" is good advice as long as you have a manageably small number of columns to pick. It will, however not be applicable in some cases where ranges span dozens (or possibly hundreds) of columns.
From command prompt Run as Administrator. Example below is to print a list of Services running on your PC run the command below:
net start > c:\netstart.txt
You should see a copy of the text file you just exported with a listing all the PC services running at the root of your C:\
drive.
@NotNull
is a JSR 303 Bean Validation annotation. It has nothing to do with database constraints itself. As Hibernate is the reference implementation of JSR 303, however, it intelligently picks up on these constraints and translates them into database constraints for you, so you get two for the price of one. @Column(nullable = false)
is the JPA way of declaring a column to be not-null. I.e. the former is intended for validation and the latter for indicating database schema details. You're just getting some extra (and welcome!) help from Hibernate on the validation annotations.
tl;dr
"Foo" and "bar" as metasyntactic variables were popularised by MIT and DEC, the first references are in work on LISP and PDP-1 and Project MAC from 1964 onwards.
Many of these people were in MIT's Tech Model Railroad Club, where we find the first documented use of "foo" in tech circles in 1959 (and a variant in 1958).
Both "foo" and "bar" (and even "baz") were well known in popular culture, especially from Smokey Stover and Pogo comics, which will have been read by many TMRC members.
Also, it seems likely the military FUBAR contributed to their popularity.
The use of lone "foo" as a nonsense word is pretty well documented in popular culture in the early 20th century, as is the military FUBAR. (Some background reading: FOLDOC FOLDOC Jargon File Jargon File Wikipedia RFC3092)
OK, so let's find some references.
STOP PRESS! After posting this answer, I discovered this perfect article about "foo" in the Friday 14th January 1938 edition of The Tech ("MIT's oldest and largest newspaper & the first newspaper published on the web"), Volume LVII. No. 57, Price Three Cents:
On Foo-ism
The Lounger thinks that this business of Foo-ism has been carried too far by its misguided proponents, and does hereby and forthwith take his stand against its abuse. It may be that there's no foo like an old foo, and we're it, but anyway, a foo and his money are some party. (Voice from the bleachers- "Don't be foo-lish!")
As an expletive, of course, "foo!" has a definite and probably irreplaceable position in our language, although we fear that the excessive use to which it is currently subjected may well result in its falling into an early (and, alas, a dark) oblivion. We say alas because proper use of the word may result in such happy incidents as the following.
It was an 8.50 Thermodynamics lecture by Professor Slater in Room 6-120. The professor, having covered the front side of the blackboard, set the handle that operates the lift mechanism, turning meanwhile to the class to continue his discussion. The front board slowly, majestically, lifted itself, revealing the board behind it, and on that board, writ large, the symbols that spelled "FOO"!
The Tech newspaper, a year earlier, the Letter to the Editor, September 1937:
By the time the train has reached the station the neophytes are so filled with the stories of the glory of Phi Omicron Omicron, usually referred to as Foo, that they are easy prey.
...
It is not that I mind having lost my first four sons to the Grand and Universal Brotherhood of Phi Omicron Omicron, but I do wish that my fifth son, my baby, should at least be warned in advance.
Hopefully yours,
Indignant Mother of Five.
And The Tech in December 1938:
General trend of thought might be best interpreted from the remarks made at the end of the ballots. One vote said, '"I don't think what I do is any of Pulver's business," while another merely added a curt "Foo."
The first documented "foo" in tech circles is probably 1959's Dictionary of the TMRC Language:
FOO: the sacred syllable (FOO MANI PADME HUM); to be spoken only when under inspiration to commune with the Deity. Our first obligation is to keep the Foo Counters turning.
These are explained at FOLDOC. The dictionary's compiler Pete Samson said in 2005:
Use of this word at TMRC antedates my coming there. A foo counter could simply have randomly flashing lights, or could be a real counter with an obscure input.
And from 1996's Jargon File 4.0.0:
Earlier versions of this lexicon derived 'baz' as a Stanford corruption of bar. However, Pete Samson (compiler of the TMRC lexicon) reports it was already current when he joined TMRC in 1958. He says "It came from "Pogo". Albert the Alligator, when vexed or outraged, would shout 'Bazz Fazz!' or 'Rowrbazzle!' The club layout was said to model the (mythical) New England counties of Rowrfolk and Bassex (Rowrbazzle mingled with (Norfolk/Suffolk/Middlesex/Essex)."
A year before the TMRC dictionary, 1958's MIT Voo Doo Gazette ("Humor suplement of the MIT Deans' office") (PDF) mentions Foocom, in "The Laws of Murphy and Finagle" by John Banzhaf (an electrical engineering student):
Further research under a joint Foocom and Anarcom grant expanded the law to be all embracing and universally applicable: If anything can go wrong, it will!
Also 1964's MIT Voo Doo (PDF) references the TMRC usage:
Yes! I want to be an instant success and snow customers. Send me a degree in: ...
Foo Counters
Foo Jung
Let's find "foo", "bar" and "foobar" published in code examples.
So, Jargon File 4.4.7 says of "foobar":
Probably originally propagated through DECsystem manuals by Digital Equipment Corporation (DEC) in 1960s and early 1970s; confirmed sightings there go back to 1972.
The first published reference I can find is from February 1964, but written in June 1963, The Programming Language LISP: its Operation and Applications by Information International, Inc., with many authors, but including Timothy P. Hart and Michael Levin:
Thus, since "FOO" is a name for itself, "COMITRIN" will treat both "FOO" and "(FOO)" in exactly the same way.
Also includes other metasyntactic variables such as: FOO CROCK GLITCH / POOT TOOR / ON YOU / SNAP CRACKLE POP / X Y Z
I expect this is much the same as this next reference of "foo" from MIT's Project MAC in January 1964's AIM-064, or LISP Exercises by Timothy P. Hart and Michael Levin:
car[((FOO . CROCK) . GLITCH)]
It shares many other metasyntactic variables like: CHI / BOSTON NEW YORK / SPINACH BUTTER STEAK / FOO CROCK GLITCH / POOT TOOP / TOOT TOOT / ISTHISATRIVIALEXCERCISE / PLOOP FLOT TOP / SNAP CRACKLE POP / ONE TWO THREE / PLANE SUB THRESHER
For both "foo" and "bar" together, the earliest reference I could find is from MIT's Project MAC in June 1966's AIM-098, or PDP-6 LISP by none other than Peter Samson:
EXPLODE, like PRIN1, inserts slashes, so (EXPLODE (QUOTE FOO/ BAR)) PRIN1's as (F O O // / B A R) or PRINC's as (F O O / B A R).
Some more recallations.
@Walter Mitty recalled on this site in 2008:
I second the jargon file regarding Foo Bar. I can trace it back at least to 1963, and PDP-1 serial number 2, which was on the second floor of Building 26 at MIT. Foo and Foo Bar were used there, and after 1964 at the PDP-6 room at project MAC.
John V. Everett recalls in 1996:
When I joined DEC in 1966, foobar was already being commonly used as a throw-away file name. I believe fubar became foobar because the PDP-6 supported six character names, although I always assumed the term migrated to DEC from MIT. There were many MIT types at DEC in those days, some of whom had worked with the 7090/7094 CTSS. Since the 709x was also a 36 bit machine, foobar may have been used as a common file name there.
Foo and bar were also commonly used as file extensions. Since the text editors of the day operated on an input file and produced an output file, it was common to edit from a .foo file to a .bar file, and back again.
It was also common to use foo to fill a buffer when editing with TECO. The text string to exactly fill one disk block was IFOO$HXA127GA$$. Almost all of the PDP-6/10 programmers I worked with used this same command string.
Daniel P. B. Smith in 1998:
Dick Gruen had a device in his dorm room, the usual assemblage of B-battery, resistors, capacitors, and NE-2 neon tubes, which he called a "foo counter." This would have been circa 1964 or so.
Robert Schuldenfrei in 1996:
The use of FOO and BAR as example variable names goes back at least to 1964 and the IBM 7070. This too may be older, but that is where I first saw it. This was in Assembler. What would be the FORTRAN integer equivalent? IFOO and IBAR?
Paul M. Wexelblat in 1992:
The earliest PDP-1 Assembler used two characters for symbols (18 bit machine) programmers always left a few words as patch space to fix problems. (Jump to patch space, do new code, jump back) That space conventionally was named FU: which stood for Fxxx Up, the place where you fixed Fxxx Ups. When spoken, it was known as FU space. Later Assemblers ( e.g. MIDAS allowed three char tags so FU became FOO, and as ALL PDP-1 programmers will tell you that was FOO space.
Bruce B. Reynolds in 1996:
On the IBM side of FOO(FU)BAR is the use of the BAR side as Base Address Register; in the middle 1970's CICS programmers had to worry out the various xxxBARs...I think one of those was FRACTBAR...
Here's a straight IBM "BAR" from 1955.
Other early references:
1973 foo bar International Joint Council on Artificial Intelligence
1975 foo bar International Joint Council on Artificial Intelligence
I haven't been able to find any references to foo bar as "inverted foo signal" as suggested in RFC3092 and elsewhere.
Here are a some of even earlier F00s but I think they're coincidences/false positives:
Go to your project, click on Build phases, Compile sources, Add GameCenterManager.m to the list.
I am trying to obtain a handle on one of the views in the Action Bar
I will assume that you mean something established via android:actionLayout
in your <item>
element of your <menu>
resource.
I have tried calling findViewById(R.id.menu_item)
To retrieve the View
associated with your android:actionLayout
, call findItem()
on the Menu
to retrieve the MenuItem
, then call getActionView()
on the MenuItem
. This can be done any time after you have inflated the menu resource.
Auth::user()->products->sum('price');
The documentation is a little light for some of the Collection
methods but all the query builder aggregates are seemingly available besides avg()
that can be found at http://laravel.com/docs/queries#aggregates.
You can cycle through the first list and, for every item that isn't in the second list but is in the first list, add it to the third list. E.g:
temp3 = []
for i in temp1:
if i not in temp2:
temp3.append(i)
print(temp3)
If the checkbox is checked, then the checkbox's value will be passed. Otherwise, the field is not passed in the HTTP post.
if (isset($_POST['mycheckbox'])) {
echo "checked!";
}
So, there's no way that this works:
window.onload = function(){
<script language="JavaScript" src="http://jact.atdmt.com/jaction/JavaScriptTest"></script>
};
You can't freely drop HTML into the middle of javascript.
If you have jQuery, you can just use:
$.getScript("http://jact.atdmt.com/jaction/JavaScriptTest")
whenever you want. If you want to make sure the document has finished loading, you can do this:
$(document).ready(function() {
$.getScript("http://jact.atdmt.com/jaction/JavaScriptTest");
});
In plain javascript, you can load a script dynamically at any time you want to like this:
var tag = document.createElement("script");
tag.src = "http://jact.atdmt.com/jaction/JavaScriptTest";
document.getElementsByTagName("head")[0].appendChild(tag);
UITableView's selectRowAtIndexPath:animated:scrollPosition: should do the trick.
Just pass UITableViewScrollPositionNone
for scrollPosition and the user won't see any movement.
You should also be able to manually run the action:
[theTableView.delegate tableView:theTableView didSelectRowAtIndexPath:indexPath]
after you selectRowAtIndexPath:animated:scrollPosition:
so the highlight happens as well as any associated logic.
I am the author of a 2048 controller that scores better than any other program mentioned in this thread. An efficient implementation of the controller is available on github. In a separate repo there is also the code used for training the controller's state evaluation function. The training method is described in the paper.
The controller uses expectimax search with a state evaluation function learned from scratch (without human 2048 expertise) by a variant of temporal difference learning (a reinforcement learning technique). The state-value function uses an n-tuple network, which is basically a weighted linear function of patterns observed on the board. It involved more than 1 billion weights, in total.
At 1 moves/s: 609104 (100 games average)
At 10 moves/s: 589355 (300 games average)
At 3-ply (ca. 1500 moves/s): 511759 (1000 games average)
The tile statistics for 10 moves/s are as follows:
2048: 100%
4096: 100%
8192: 100%
16384: 97%
32768: 64%
32768,16384,8192,4096: 10%
(The last line means having the given tiles at the same time on the board).
For 3-ply:
2048: 100%
4096: 100%
8192: 100%
16384: 96%
32768: 54%
32768,16384,8192,4096: 8%
However, I have never observed it obtaining the 65536 tile.

<asp:RadioButtonList runat="server" ID="Intent">
<asp:ListItem Value="Confirm">Yes!</asp:ListItem>
<asp:ListItem Value="Postpone">Not now</asp:ListItem>
<asp:ListItem Value="Decline">Never!</asp:ListItem>
</asp:RadioButtonList>
The handler:
$(document).ready(function () {
$("#<%=Intent.ClientID%>").change(function(){
var rbvalue = $("input[name='<%=Intent.UniqueID%>']:radio:checked").val();
if(rbvalue == "Confirm"){
alert("Woohoo, Thanks!");
} else if (rbvalue == "Postpone"){
alert("Well, I really hope it's soon");
} else if (rbvalue == "Decline"){
alert("Shucks!");
} else {
alert("How'd you get here? Who sent you?");
}
});
});
The important part: $("input[name='<%=Intent.UniqueID%>']:radio:checked").val();
From RFC 1945 (HTTP/1.0) and RFC 2617 (HTTP Authentication referenced by HTTP/1.1)
The realm attribute (case-insensitive) is required for all authentication schemes which issue a challenge. The realm value (case-sensitive), in combination with the canonical root URL of the server being accessed, defines the protection space. These realms allow the protected resources on a server to be partitioned into a set of protection spaces, each with its own authentication scheme and/or authorization database. The realm value is a string, generally assigned by the origin server, which may have additional semantics specific to the authentication scheme.
In short, pages in the same realm should share credentials. If your credentials work for a page with the realm "My Realm", it should be assumed that the same username and password combination should work for another page with the same realm.

So, let's say you have this table:
CREATE TABLE YourTable(Col1 VARCHAR(10))
And you want to change Col1
to VARCHAR(20)
. What you need to do is this:
ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)
That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5)
, then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE
will fail.

You get a unix timestamp in C# by using DateTime.UtcNow
and subtracting the epoch time of 1970-01-01.
e.g.
Int32 unixTimestamp = (Int32)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;
DateTime.UtcNow
can be replaced with any DateTime
object that you would like to get the unix timestamp for.
There is also a field, DateTime.UnixEpoch
, which is very poorly documented by MSFT, but may be a substitute for new DateTime(1970, 1, 1)
This is one of the method to overcome this issue.

With
with() is for eager loading. That basically means, along the main model, Laravel will preload the relationship(s) you specify. This is especially helpful if you have a collection of models and you want to load a relation for all of them. Because with eager loading you run only one additional DB query instead of one for every model in the collection.
Example:
User > hasMany > Post
$users = User::with('posts')->get();
foreach($users as $user){
$users->posts; // posts is already loaded and no additional DB query is run
}
Has
has() is to filter the selecting model based on a relationship. So it acts very similarly to a normal WHERE condition. If you just use has('relation') that means you only want to get the models that have at least one related model in this relation.
Example:
User > hasMany > Post
$users = User::has('posts')->get();
// only users that have at least one post are contained in the collection
WhereHas
whereHas() works basically the same as has() but allows you to specify additional filters for the related model to check.
Example:
User > hasMany > Post
$users = User::whereHas('posts', function($q){
$q->where('created_at', '>=', '2015-01-01 00:00:00');
})->get();
// only users that have posts from 2015 on forward are returned
You can use RegEdit to export the following two keys:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
HKEY_CURRENT_USER\Environment
The first set are system/global environment variables; the second set are user-level variables. Edit as needed and then import the .reg files on the new machine.

display: -webkit-box;
-webkit-box-orient: vertical;

max-height: @line-height * @lines;
}
.example-1 {
.max-lines();
}
.example-2 {
.max-lines(3);
}
.example-3 {
.max-lines(3, 1.5);
}

I had this same issue when trying to handle popping alerts and fading them. I searched around various places and found this to be my solution. Adding and removing the 'in' class fixed my issue.
window.setTimeout(function() { // hide alert message
$("#alert_message").removeClass('in');
}, 5000);
When using .remove() and similarly the .alert('close') solution I seemed to hit an issue with the alert being removed from the document, so if I wanted to use the same alert div again I was unable to. This solution means the alert is reusable without refreshing the page. (I was using aJax to submit a form and present feedback to the user)
$('#Some_Button_Or_Event_Here').click(function () { // Show alert message
$('#alert_message').addClass('in');
});

With python or pandas when you use read_csv
or pd.read_csv
, both of them look into current working directory, by default where the python process have started. So you need to use os
module to chdir()
and take it from there.
import pandas as pd
import os
print(os.getcwd())
os.chdir("D:/01Coding/Python/data_sets/myowndata")
print(os.getcwd())
df = pd.read_csv('data.csv',nrows=10)
print(df.head())
You can set this globally for all read.csv/read.*
commands with
options(stringsAsFactors=F)
Then read the file as follows:
my.tab <- read.table( "filename.csv", as.is=T )
you can get a files modified date using vbscript too
Set objFS=CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
strFile= objArgs(0)
WScript.Echo objFS.GetFile(strFile).DateLastModified
save the above as mygetdate.vbs and on command line
c:\test> cscript //nologo mygetdate.vbs myfile
All this arises because git does not provide an option in clone/pull/push/fetch commands to send the credentials through a pipe. Though it gives credential.helper, it stores on the file system or creates a daemon etc. Often, the credentials of GIT are system level ones and onus to keep them safe is on the application invoking the git commands. Very unsafe indeed.
Here is what I had to work around. 1. Git version (git --version) should be greater than or equal to 1.8.3.
GIT CLONE
For cloning, use "git clone URL" after changing the URL from the format, http://{myuser}@{my_repo_ip_address}/{myrepo_name.git} to http://{myuser}:{mypwd}@{my_repo_ip_address}/{myrepo_name.git}
Then purge the repository of the password as in the next section.
PURGING
Now, this would have gone and
If your application is using Java to issue these commands, use ProcessBuilder instead of Runtime. If you must use Runtime, use getRunTime().exec which takes String array as arguments with /bin/bash and -c as arguments rather then the one which takes a single String as argument.
GIT FETCH/PULL/PUSH
For android source code with repo, I beleive you should use REPO. if you really want to use git, you should know if the project has .git directory with ls -a. Or you have to enter the sub project directory which should include the .git.
One of the reasons why the global variable needs a prefix (called a "sigil") is because in Ruby, unlike in C, you don't have to declare your variables before assigning to them. The sigil is used as a way to be explicit about the scope of the variable.
Without a specific prefix for globals, given a statement pointNew = offset + point
inside your draw
method then offset
refers to a local variable inside the method (and results in a NameError
in this case). The same for @
used to refer to instance variables and @@
for class variables.
In other languages that use explicit declarations such as C
, Java
etc. the placement of the declaration is used to control the scope.
It means that it is a wide character, wchar_t
.
Similar to 1L
being a long value.

I knew that Kaspersky is intercepting the SSL connections to check for malicious content from the sites and I decided to disable it, but I found that KAV is hung and not really responding, so I just closed Kaspersky and tried to connect to github.com again and alas! I was able to connect successfully to GitHub.
So in you case it may be a similar issue.
I had this Error too and was able to solve it after days of debugging and analysis:
For me VirtualBox (for Docker) was the Problem. I had Port Forwarding configured on my VM and the error only occured on the forwarded port.
The following observations may save you days of work I had to invest:
-> figure out if something is messing around with your network (-settings), like VMs, Firewalls etc., this is probably the cause of the problem.
Another option is to apply flex styling at the table row, and add the col-classes
to the table header / table data elements:
<table>
<thead>
<tr class="d-flex">
<th class="col-3">3 columns wide header</th>
<th class="col-sm-5">5 columns wide header</th>
<th class="col-sm-4">4 columns wide header</th>
</tr>
</thead>
<tbody>
<tr class="d-flex">
<td class="col-3">3 columns wide content</th>
<td class="col-sm-5">5 columns wide content</th>
<td class="col-sm-4">4 columns wide content</th>
</tr>
</tbody>
</table>
try this:
SELECT * FROM TableA
JOIN TableB ON TableA.primary_key = TableB.foreign_key
JOIN TableB ON TableB.foreign_key = TableC.foreign_key
In simple words:
var x = (day == "yes") ? "Good Day!" : (day == "no") ? "Good Night!" : "";
Full process (Unix svn package):
Check files are not in SVN:
> svn st -u folder
? folder
Add all (including ignored files):
> svn add folder
A folder
A folder/file1.txt
A folder/folder2
A folder/folder2/file2.txt
A folder/folderToIgnore
A folder/folderToIgnore/fileToIgnore1.txt
A fileToIgnore2.txt
Remove "Add" Flag to All * Ignore * files:
> cd folder
> svn revert --recursive folderToIgnore
Reverted 'folderToIgnore'
Reverted 'folderToIgnore/fileToIgnore1.txt'
> svn revert fileToIgnore2.txt
Reverted 'fileToIgnore2.txt'
Edit svn ignore on folder
svn propedit svn:ignore .
Add two singles lines with just the following:
folderToIgnore
fileToIgnore2.txt
Check which files will be upload and commit:
> cd ..
> svn st -u
A folder
A folder/file1.txt
A folder/folder2
A folder/folder2/file2.txt
> svn ci -m "Commit message here"
Construct a SimpleDateFormat with the mask, and then call: SimpleDateFormat.parse(String s, ParsePosition p)
Using to_char:
select to_char(sysdate, 'YYYY') from dual;
In your example you can use something like:
BETWEEN trunc(sysdate, 'YEAR')
AND add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60;
The comparison values are exactly what you request:
select trunc(sysdate, 'YEAR') begin_year
, add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60 last_second_year
from dual;
BEGIN_YEAR LAST_SECOND_YEAR

Here is a version with configurable parameters that you can set programmatically:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="utf-8" />
<xsl:param name="delim" select="','" />
<xsl:param name="quote" select="'"'" />
<xsl:param name="break" select="'
'" />
<xsl:template match="/">
<xsl:apply-templates select="projects/project" />
</xsl:template>
<xsl:template match="project">
<xsl:apply-templates />
<xsl:if test="following-sibling::*">
<xsl:value-of select="$break" />
</xsl:if>
</xsl:template>
<xsl:template match="*">
<!-- remove normalize-space() if you want keep white-space at it is -->
<xsl:value-of select="concat($quote, normalize-space(), $quote)" />
<xsl:if test="following-sibling::*">
<xsl:value-of select="$delim" />
</xsl:if>
</xsl:template>
<xsl:template match="text()" />
</xsl:stylesheet>
When you use Context.SECURITY_AUTHENTICATION as "simple", you need to supply the userPrincipalName attribute value (user@domain_base).
there is one more difference, but only in internet explorer. It occurs when you mix HTML and SVG. if the parent is the 'other' of those two, then .parentNode gives the parent, while .parentElement gives undefined.
try this:
a = new Array();
a.push(10);
a.push(60);
a.push(20);
a.push(30);
a.push(100);
a.sort(Test)
document.write(a);
function Test(a,b)
{
return a > b ? true : false;
}
javac only compiles the code. You need to use java command to run the code. The error is because your classpath doesn't contain the class Subclass iwhen you tried to compile it. you need to add them with the -cp variable in javac command
java -cp classpath-entries mainjava arg1 arg2
should run your code with 2 arguments
Your code sets the timeout to 1000 seconds. For milliseconds, use CURLOPT_TIMEOUT_MS
.
i think this is shortest code for finding primes with eratosthenes method
def prime(r):
n = range(2,r)
while len(n)>0:
yield n[0]
n = [x for x in n if x not in range(n[0],r,n[0])]
print(list(prime(r)))
