Based on @erakitin answer, but also compatible for Android versions < API level 17. Sadly Activity.isDestroyed() is only supported since API level 17, so if you're targeting an older API level just like me, you'll have to check it yourself. Haven't got the View not attached to window manager
exception after that.
Example code
public class MainActivity extends Activity {
private TestAsyncTask mAsyncTask;
private ProgressDialog mProgressDialog;
private boolean mIsDestroyed;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (condition) {
mAsyncTask = new TestAsyncTask();
mAsyncTask.execute();
}
}
@Override
protected void onResume() {
super.onResume();
if (mAsyncTask != null && mAsyncTask.getStatus() != AsyncTask.Status.FINISHED) {
Toast.makeText(this, "Still loading", Toast.LENGTH_LONG).show();
return;
}
}
@Override
protected void onDestroy() {
super.onDestroy();
mIsDestroyed = true;
if (mProgressDialog != null && mProgressDialog.isShowing()) {
mProgressDialog.dismiss();
}
}
public class TestAsyncTask extends AsyncTask<Void, Void, AsyncResult> {
@Override
protected void onPreExecute() {
super.onPreExecute();
mProgressDialog = ProgressDialog.show(MainActivity.this, "Please wait", "doing stuff..");
}
@Override
protected AsyncResult doInBackground(Void... arg0) {
// Do long running background stuff
return null;
}
@Override
protected void onPostExecute(AsyncResult result) {
// Use MainActivity.this.isDestroyed() when targeting API level 17 or higher
if (mIsDestroyed)// Activity not there anymore
return;
mProgressDialog.dismiss();
// Handle rest onPostExecute
}
}
}
This command should work:
sed "s/\s/,/g" < infile.txt > outfile.txt
Note that you have to redirect the output to a new file. The input file is not changed in place.
Javascript will do the trick here.
function load() {
var file = new XMLHttpRequest();
file.open("GET", "http://remote.tld/random.txt", true);
file.onreadystatechange = function() {
if (file.readyState === 4) { // Makes sure the document is ready to parse
if (file.status === 200) { // Makes sure it's found the file
text = file.responseText;
document.getElementById("div1").innerHTML = text;
}
}
}
}
window.onLoad = load();
For easy fix follow these steps:
When I drag files in, the "Add to targets" box seems to be un-ticked by default. If I leave it un-ticked then I have the problem described. Fix it by deleting the files then dragging them back in but making sure to tick "Add to targets".
The other answers will break if output of command contains spaces (which is rather frequent) or glob characters like *
, ?
, [...]
.
To get the output of a command in an array, with one line per element, there are essentially 3 ways:
With Bash=4 use mapfile
—it's the most efficient:
mapfile -t my_array < <( my_command )
Otherwise, a loop reading the output (slower, but safe):
my_array=()
while IFS= read -r line; do
my_array+=( "$line" )
done < <( my_command )
As suggested by Charles Duffy in the comments (thanks!), the following might perform better than the loop method in number 2:
IFS=$'\n' read -r -d '' -a my_array < <( my_command && printf '\0' )
Please make sure you use exactly this form, i.e., make sure you have the following:
IFS=$'\n'
on the same line as the read
statement: this will only set the environment variable IFS
for the read
statement only. So it won't affect the rest of your script at all. The purpose of this variable is to tell read
to break the stream at the EOL character \n
.-r
: this is important. It tells read
to not interpret the backslashes as escape sequences.-d ''
: please note the space between the -d
option and its argument ''
. If you don't leave a space here, the ''
will never be seen, as it will disappear in the quote removal step when Bash parses the statement. This tells read
to stop reading at the nil byte. Some people write it as -d $'\0'
, but it is not really necessary. -d ''
is better.-a my_array
tells read
to populate the array my_array
while reading the stream.printf '\0'
statement after my_command
, so that read
returns 0
; it's actually not a big deal if you don't (you'll just get an return code 1
, which is okay if you don't use set -e
– which you shouldn't anyway), but just bear that in mind. It's cleaner and more semantically correct. Note that this is different from printf ''
, which doesn't output anything. printf '\0'
prints a null byte, needed by read
to happily stop reading there (remember the -d ''
option?).If you can, i.e., if you're sure your code will run on Bash=4, use the first method. And you can see it's shorter too.
If you want to use read
, the loop (method 2) might have an advantage over method 3 if you want to do some processing as the lines are read: you have direct access to it (via the $line
variable in the example I gave), and you also have access to the lines already read (via the array ${my_array[@]}
in the example I gave).
Note that mapfile
provides a way to have a callback eval'd on each line read, and in fact you can even tell it to only call this callback every N lines read; have a look at help mapfile
and the options -C
and -c
therein. (My opinion about this is that it's a little bit clunky, but can be used sometimes if you only have simple things to do — I don't really understand why this was even implemented in the first place!).
Now I'm going to tell you why the following method:
my_array=( $( my_command) )
is broken when there are spaces:
$ # I'm using this command to test:
$ echo "one two"; echo "three four"
one two
three four
$ # Now I'm going to use the broken method:
$ my_array=( $( echo "one two"; echo "three four" ) )
$ declare -p my_array
declare -a my_array='([0]="one" [1]="two" [2]="three" [3]="four")'
$ # As you can see, the fields are not the lines
$
$ # Now look at the correct method:
$ mapfile -t my_array < <(echo "one two"; echo "three four")
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # Good!
Then some people will then recommend using IFS=$'\n'
to fix it:
$ IFS=$'\n'
$ my_array=( $(echo "one two"; echo "three four") )
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # It works!
But now let's use another command, with globs:
$ echo "* one two"; echo "[three four]"
* one two
[three four]
$ IFS=$'\n'
$ my_array=( $(echo "* one two"; echo "[three four]") )
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="t")'
$ # What?
That's because I have a file called t
in the current directory… and this filename is matched by the glob [three four]
… at this point some people would recommend using set -f
to disable globbing: but look at it: you have to change IFS
and use set -f
to be able to fix a broken technique (and you're not even fixing it really)! when doing that we're really fighting against the shell, not working with the shell.
$ mapfile -t my_array < <( echo "* one two"; echo "[three four]")
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="[three four]")'
here we're working with the shell!
You just need to override the method for back button. You can leave the method empty if you want so that nothing will happen when you press back button. Please have a look at the code below:
@Override
public void onBackPressed()
{
// Your Code Here. Leave empty if you want nothing to happen on back press.
}
Options menu in android can be customized to set the background or change the text appearance. The background and text color in the menu couldn’t be changed using themes and styles. The android source code (data\res\layout\icon_menu_item_layout.xml)uses a custom item of class “com.android.internal.view.menu.IconMenuItem”View for the menu layout. We can make changes in the above class to customize the menu. To achieve the same, use LayoutInflater factory class and set the background and text color for the view.
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.my_menu, menu);
getLayoutInflater().setFactory(new Factory() {
@Override
public View onCreateView(String name, Context context, AttributeSet attrs) {
if (name .equalsIgnoreCase(“com.android.internal.view.menu.IconMenuItemView”)) {
try{
LayoutInflater f = getLayoutInflater();
final View view = f.createView(name, null, attrs);
new Handler().post(new Runnable() {
public void run() {
// set the background drawable
view .setBackgroundResource(R.drawable.my_ac_menu_background);
// set the text color
((TextView) view).setTextColor(Color.WHITE);
}
});
return view;
} catch (InflateException e) {
} catch (ClassNotFoundException e) {}
}
return null;
}
});
return super.onCreateOptionsMenu(menu);
}
S.Lott inserted a comment, but it should be an answer: see the same question.
Since it wasn't as obvious as I intended it to be, here follows a verbatim copy of S.Lott's answer in the other question:
I'm a big fan of ARGO UML from Tigris.org. Draws nice pictures using standard UML notation. It does some code generation, but mostly Java classes, which isn't SQL DDL, so that may not be close enough to what you want to do.
You can look at the Data Modelling Tools list and see if anything there is better than Argo UML. Many of the items on this list are free or cheap.
Also, if you're using Eclipse or NetBeans, there are many design plug-ins, some of which may have the features you're looking for.
What worked for me now is:
CSS:
.right {
text-align: right;
margin-right: 1em;
}
.left {
text-align: left;
margin-left: 1em;
}
HTML:
<table width="100%">
<tbody>
<tr>
<td class="left">
<input id="abort" type="submit" name="abort" value="Back">
<input id="save" type="submit" name="save" value="Save">
</td>
<td class="right">
<input id="delegate" type="submit" name="delegate" value="Delegate">
<input id="unassign" type="submit" name="unassign" value="Unassign">
<input id="complete" type="submit" name="complete" value="Complete">
</td>
</tr>
</tbody>
</table>
See the following fiddle:
ETag is used to determine whether a resource should use the copy one. and Expires Header like Cache-Control is told the client that before the cache decades, client should fetch the local resource.
In modern sites, There are often offer a file named hash, like app.98a3cf23.js
, so that it's a good practice to use Expires Header. Besides this, it also reduce the cost of network.
Hope it helps ;)
If you want to find the rows
that have any of the values in a vector, one option is to loop the vector (lapply(v1,..)
), create a logical index of (TRUE/FALSE) with (==
). Use Reduce
and OR (|
) to reduce the list to a single logical matrix by checking the corresponding elements. Sum the rows (rowSums
), double negate (!!
) to get the rows with any matches.
indx1 <- !!rowSums(Reduce(`|`, lapply(v1, `==`, df)), na.rm=TRUE)
Or vectorise and get the row indices with which
with arr.ind=TRUE
indx2 <- unique(which(Vectorize(function(x) x %in% v1)(df),
arr.ind=TRUE)[,1])
I didn't use @kristang's solution as it is giving me errors. Based on a 1000x500
matrix, @konvas's solution is the most efficient (so far). But, this may vary if the number of rows are increased
val <- paste0('M0', 1:1000)
set.seed(24)
df1 <- as.data.frame(matrix(sample(c(val, NA), 1000*500,
replace=TRUE), ncol=500), stringsAsFactors=FALSE)
set.seed(356)
v1 <- sample(val, 200, replace=FALSE)
konvas <- function() {apply(df1, 1, function(r) any(r %in% v1))}
akrun1 <- function() {!!rowSums(Reduce(`|`, lapply(v1, `==`, df1)),
na.rm=TRUE)}
akrun2 <- function() {unique(which(Vectorize(function(x) x %in%
v1)(df1),arr.ind=TRUE)[,1])}
library(microbenchmark)
microbenchmark(konvas(), akrun1(), akrun2(), unit='relative', times=20L)
#Unit: relative

I had a similar issue. I added write permissions to the .bak file itself, and my folder that I was writing the backup to for the NETWORK SERVICE user. To add permissions just right-click what file/directory you want to alter, select the security tab, and add the appropriate users/permissions there.
As others have said, in general you use @synthesize to have the compiler generate the getters and/ or settings for you, and @dynamic if you are going to write them yourself.
There is another subtlety not yet mentioned: @synthesize will let you provide an implementation yourself, of either a getter or a setter. This is useful if you only want to implement the getter for some extra logic, but let the compiler generate the setter (which, for objects, is usually a bit more complex to write yourself).
However, if you do write an implementation for a @synthesize'd accessor it must still be backed by a real field (e.g., if you write -(int) getFoo();
you must have an int foo;
field). If the value is being produce by something else (e.g. calculated from other fields) then you have to use @dynamic.
You could put an application.properties file in your test/resources folder. There you set
spring.profiles.active=test
This is kind of a default test profile while running tests.
I tried several methods which failed, but the below worked for me like a charm:
$('#myModal').appendTo("body").modal('show');
Try dir /b
, for bare format.
dir /?
will show you documentation of what you can do with the dir
command. Here is the output from my Windows 7 machine:
C:\>dir /?
Displays a list of files and subdirectories in a directory.
DIR [drive:][path][filename] [/A[[:]attributes]] [/B] [/C] [/D] [/L] [/N]
[/O[[:]sortorder]] [/P] [/Q] [/R] [/S] [/T[[:]timefield]] [/W] [/X] [/4]
[drive:][path][filename]
Specifies drive, directory, and/or files to list.
/A Displays files with specified attributes.
attributes D Directories R Read-only files
H Hidden files A Files ready for archiving
S System files I Not content indexed files
L Reparse Points - Prefix meaning not
/B Uses bare format (no heading information or summary).
/C Display the thousand separator in file sizes. This is the
default. Use /-C to disable display of separator.
/D Same as wide but files are list sorted by column.
/L Uses lowercase.
/N New long list format where filenames are on the far right.
/O List by files in sorted order.
sortorder N By name (alphabetic) S By size (smallest first)
E By extension (alphabetic) D By date/time (oldest first)
G Group directories first - Prefix to reverse order
/P Pauses after each screenful of information.
/Q Display the owner of the file.
/R Display alternate data streams of the file.
/S Displays files in specified directory and all subdirectories.
/T Controls which time field displayed or used for sorting
timefield C Creation
A Last Access
W Last Written
/W Uses wide list format.
/X This displays the short names generated for non-8dot3 file
names. The format is that of /N with the short name inserted
before the long name. If no short name is present, blanks are
displayed in its place.
/4 Displays four-digit years
Switches may be preset in the DIRCMD environment variable. Override
preset switches by prefixing any switch with - (hyphen)--for example, /-W.
If you're developing something more complicated and want multiple columns to be fixed/stuck to the left, you'll probably need something like this.

I repeatedly had the same challenge sometime ago. This problem occurs mostly when you are trying to pull from the remote repository and you have some files on your local instance conflicting with the remote version, if you are using git from an IDE such as IntelliJ, you will be prompted and allowed to make a choice if you want to retain your own changes or you prefer the changes in the remote version to overwrite yours'. If you don't make any choice then you fall into this conflict. all you need to do is run:
git merge --abort # The unresolved conflict will be cleared off
And you can continue what you were doing before the break.
Both call()
and apply()
are methods which are located on Function.prototype
. Therefore they are available on every function object via the prototype chain. Both call()
and apply()
can execute a function with a specified value of the this
.
The main difference between call()
and apply()
is the way you have to pass in arguments into it. In both call()
and apply()
you pass as a first argument the object you want to be the value as this
. The other arguments differ in the following way:
call()
you have to put in the arguments normally (starting from the second argument)apply()
you have to pass in array of arguments.let obj = {_x000D_
val1: 5,_x000D_
val2: 10_x000D_
}_x000D_
_x000D_
const summation = function (val3, val4) {_x000D_
return this.val1 + this.val2 + val3 + val4;_x000D_
}_x000D_
_x000D_
console.log(summation.apply(obj, [2 ,3]));_x000D_
// first we assign we value of this in the first arg_x000D_
// with apply we have to pass in an array_x000D_
_x000D_
_x000D_
console.log(summation.call(obj, 2, 3));_x000D_
// with call we can pass in each arg individually
_x000D_
The this
value can be tricky sometimes in javascript. The value of this
determined when a function is executed not when a function is defined. If our function is dependend on a right this
binding we can use call()
and apply()
to enforce this behaviour. For example:
var name = 'unwantedGlobalName';_x000D_
_x000D_
const obj = {_x000D_
name: 'Willem',_x000D_
sayName () { console.log(this.name);}_x000D_
}_x000D_
_x000D_
_x000D_
let copiedMethod = obj.sayName;_x000D_
// we store the function in the copiedmethod variable_x000D_
_x000D_
_x000D_
_x000D_
copiedMethod();_x000D_
// this is now window, unwantedGlobalName gets logged_x000D_
_x000D_
copiedMethod.call(obj);_x000D_
// we enforce this to be obj, Willem gets logged
_x000D_
$.fn.scrollEnd = function(callback, timeout) {
$(this).scroll(function(){
var $this = $(this);
if ($this.data('scrollTimeout')) {
clearTimeout($this.data('scrollTimeout'));
}
$this.data('scrollTimeout', setTimeout(callback,timeout));
});
};
$(window).scroll(function(){
$('.main').fadeOut();
});
$(window).scrollEnd(function(){
$('.main').fadeIn();
}, 700);
That should do the Trick!

using System.Configuration;
in code
SqlConnection conn = new SqlConnection(*ConfigurationManager.ConnectionStrings["connstrname"].ConnectionString*);
The command looks quite fine. Could you try to run -v (verbose mode) and then we can figure out what it is wrong on the authentication?
Also as mention in the other answer, maybe could be this issue - that you need to convert the keys (answered already here): How to convert SSH keypairs generated using PuttyGen(Windows) into key-pairs used by ssh-agent and KeyChain(Linux) OR http://winscp.net/eng/docs/ui_puttygen (depending what you need)
If you're having this problem in a stored procedure and you aren't able to use the key in the WHERE clause, you can solve this by declaring a variable that will hold the limit of the rows that should be updated and then use it in the update/delete query.
DELIMITER $
CREATE PROCEDURE myProcedure()
BEGIN
DECLARE the_limit INT;
SELECT COUNT(*) INTO the_limit
FROM my_table
WHERE my_column IS NULL;
UPDATE my_table
SET my_column = true
WHERE my_column IS NULL
LIMIT the_limit;
END$
For React.js, you can do this with more readable code. Hope it helps.

console.log('value of checkbox : ', e.target.checked);
}
render() {
return <input type="checkbox" onChange={this.handleCheckboxChange.bind(this)} />
}
My version of this is an adaptation of Arvo's work, with a little more added on to ensure two other cases.
1) If we have all 0s, we should return the digit 0.
2) If we have a blank, we should still return a blank character.
CASE
WHEN PATINDEX('%[^0]%', str_col + '.') > LEN(str_col) THEN RIGHT(str_col, 1)
ELSE SUBSTRING(str_col, PATINDEX('%[^0]%', str_col + '.'), LEN(str_col))

Unfortunately, the DateTime class doesn't have the convenience methods available in the Time class to do this. You can convert any DateTime object into UTC like this:
d = DateTime.now
d.new_offset(Rational(0, 24))
You can switch back from UTC to localtime using:
d.new_offset(DateTime.now.offset)
where d
is a DateTime object in UTC time. If you'd like these as convenience methods, then you can create them like this:
class DateTime
def localtime
new_offset(DateTime.now.offset)
end
def utc
new_offset(Rational(0, 24))
end
end
You can see this in action in the following irb session:
d = DateTime.now.new_offset(Rational(-4, 24))
=> #<DateTime: 106105391484260677/43200000000,-1/6,2299161>
1.8.7 :185 > d.to_s
=> "2012-08-03T15:42:48-04:00"
1.8.7 :186 > d.localtime.to_s
=> "2012-08-03T12:42:48-07:00"
1.8.7 :187 > d.utc.to_s
=> "2012-08-03T19:42:48+00:00"
As you can see above, the initial DateTime object has a -04:00 offset (Eastern Time). I'm in Pacific Time with a -07:00 offset. Calling localtime
as described previously properly converts the DateTime object into local time. Calling utc
on the object properly converts it to a UTC offset.
This are the steps to run again this migration file "20150927161307_create_users.rb"
Copy and past the class which is in that file to the console.
class CreateUsers < ActiveRecord::Migration
def change
create_table :users do |t|
t.string :name
t.string :email
t.timestamps null: false end
end
end
end
Create an instance of the class CreateUsers
: c1 = CreateUsers.new
change
of that instance: c1.change
Short answer: Use the change
event. Here's a couple of practical examples. Since I misread the question, I'll include jQuery examples along with plain JavaScript. You're not gaining much, if anything, by using jQuery though.
Using querySelector
.
var checkbox = document.querySelector("input[name=checkbox]");
checkbox.addEventListener('change', function() {
if (this.checked) {
console.log("Checkbox is checked..");
} else {
console.log("Checkbox is not checked..");
}
});
_x000D_
<input type="checkbox" name="checkbox" />
_x000D_
$('input[name=checkbox]').change(function() {
if ($(this).is(':checked')) {
console.log("Checkbox is checked..")
} else {
console.log("Checkbox is not checked..")
}
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" name="checkbox" />
_x000D_
Here's an example of a list of checkboxes. To select multiple elements we use querySelectorAll
instead of querySelector
. Then use Array.filter
and Array.map
to extract checked values.
// Select all checkboxes with the name 'settings' using querySelectorAll.
var checkboxes = document.querySelectorAll("input[type=checkbox][name=settings]");
let enabledSettings = []
/*
For IE11 support, replace arrow functions with normal functions and
use a polyfill for Array.forEach:
https://vanillajstoolkit.com/polyfills/arrayforeach/
*/
// Use Array.forEach to add an event listener to each checkbox.
checkboxes.forEach(function(checkbox) {
checkbox.addEventListener('change', function() {
enabledSettings =
Array.from(checkboxes) // Convert checkboxes to an array to use filter and map.
.filter(i => i.checked) // Use Array.filter to remove unchecked checkboxes.
.map(i => i.value) // Use Array.map to extract only the checkbox values from the array of objects.
console.log(enabledSettings)
})
});
_x000D_
<label>
<input type="checkbox" name="settings" value="forcefield">
Enable forcefield

<input type="checkbox" name="settings" value="invisibilitycloak">

<input type="checkbox" name="settings" value="warpspeed">

_x000D_
let checkboxes = $("input[type=checkbox][name=settings]")
let enabledSettings = [];
// Attach a change event handler to the checkboxes.
checkboxes.change(function() {
enabledSettings = checkboxes
.filter(":checked") // Filter out unchecked boxes.
.map(function() { // Extract values using jQuery map.
return this.value;
})
.get() // Get array.
console.log(enabledSettings);
});

Use
// aspect-type.js
class AspectType {
}
export default AspectType;
Then to import it
// some-other-file.js
import AspectType from './aspect-type';

sometimes, you need to limit the string to the last complete word ie: you don't want the last word to be broken instead you stop with the second last word.
eg: we need to limit "This is my String" to 6 chars but instead of 'This i..." we want it to be 'This..." ie we will skip that broken letters in the last word.
phew, am bad at explaining, here is the code.
class Fun {
public function limit_text($text, $len) {
if (strlen($text) < $len) {
return $text;
}
$text_words = explode(' ', $text);
$out = null;
foreach ($text_words as $word) {
if ((strlen($word) > $len) && $out == null) {
return substr($word, 0, $len) . "...";
}
if ((strlen($out) + strlen($word)) > $len) {
return $out . "...";
}
$out.=" " . $word;
}
return $out;
}
}
Use the formatting operator %
:
buf = "A = %d\n , B= %s\n" % (a, b)
print >>f, buf
I think you meant to do url[i] <- paste(...
instead of url[i] = paste(...
. If so replace =
with <-
.
var message =/*[[${message}]]*/ 'defaultanyvalue';
$('input[name=myradiobutton]:radio:checked')
will get you the selected radio button
$('input[name=myradiobutton]:radio:not(:checked)')
will get you the unselected radio buttons
Using this you can do this
$('input[name=myradiobutton]:radio:not(:checked)').val("0");
Update: After reading your Update I think I understand You will want to do something like this
var myRadioValue;
function radioValue(jqRadioButton){
if (jqRadioButton.length) {
myRadioValue = jqRadioButton.val();
}
else {
myRadioValue = 0;
}
}
$(document).ready(function () {
$('input[name=myradiobutton]:radio').click(function () { //Hook the click event for selected elements
radioValue($('input[name=myradiobutton]:radio:checked'));
});
radioValue($('input[name=myradiobutton]:radio:checked')); //check for value on page load
});
Use 'utf8mb4' as encoding to cover all unicode (including emojis)

password: <%= ENV.fetch("MYSQL_PASSWORD") %>
host: <%= ENV.fetch("MYSQL_HOST") %>

axios.put(url,{body},{headers:{}})
example:
const body = {title: "what!"}
const api = {
apikey: "safhjsdflajksdfh",
Authorization: "Basic bwejdkfhasjk"
}
axios.put('https://api.xxx.net/xx', body, {headers: api})
To complete other answers:
Synchronization is only a worry when the code in your method does one of two things:
This means that variables defined WITHIN your method are always threadsafe. Every call to a method has its own version of these variables. If the method is called by another thread, or by the same thread, or even if the method calls itself (recursion), the values of these variables are not shared.
Thread scheduling is not guaranteed to be round-robin. A task may totally hog the CPU at the expense of threads of the same priority. You can use Thread.yield() to have a conscience. You can use (in java) Thread.setPriority(Thread.NORM_PRIORITY-1) to lower a thread's priority
Plus beware of:
I prefer this way, because evryone will understand it clearly at the first glance:
SELECT
12 * (YEAR(to) - YEAR(from)) + (MONTH(to) - MONTH(from)) AS months
FROM
tab;
If the array is:
int arr[] = {1, 2, 3};
int len = (sizeof(arr)/sizeof(arr[0])); // finding length of array
vector < int > v;
std:: v.assign(arr, arr+len); // assigning elements from array to vector
Use HttpWebRequest.BeginGetResponse()
HttpWebRequest webRequest;
void StartWebRequest()
{
webRequest.BeginGetResponse(new AsyncCallback(FinishWebRequest), null);
}
void FinishWebRequest(IAsyncResult result)
{
webRequest.EndGetResponse(result);
}
The callback function is called when the asynchronous operation is complete. You need to at least call EndGetResponse()
from this function.
It's easier to help you if you say what's wrong as well, or what fails when you run it.
But from a quick glance you've confused a few things.
The following doesn't work because of a couple of issues.
if (Directory("C:\\csharp\\error report1.xls") = "")
What you are trying to do is creating a new Directory object that should point to a file and then check if there was any errors.
What you are actually doing is trying to call a function named Directory() and then assign a string to the result. This won't work since 1/ you don't have a function named Directory(string str) and you cannot assign to the result from a function (you can only assign a value to a variable).
What you should do (for this line at least) is the following
FileInfo fi = new FileInfo("C:\\csharp\\error report1.xls");
if(!fi.Exists)
{
// Create the xl file here
}
else
{
// Open file here
}
As to why the Excel code doesn't work, you have to check the documentation for the Excel library which google should be able to provide for you.
Use accept attribute with the MIME_type as values
<input type="file" accept="image/gif, image/jpeg" />
Actually, you need to call SET SERVEROUTPUT ON;
before the BEGIN
call.
Everyone suggested this but offers no advice where to actually place the line:
SET SERVEROUTPUT ON;
BEGIN
FOR rec in (SELECT * FROM EMPLOYEES) LOOP
DBMS_OUTPUT.PUT_LINE(rec.EmployeeName);
ENDLOOP;
END;
Otherwise, you won't see any output.
as Artyom said you need to use ngChange and pass ngModel object as argument to your ngChange function
Example:
<div ng-app="App" >
<div ng-controller="ctrl">
<select ng-model="blisterPackTemplateSelected" ng-change="changedValue(blisterPackTemplateSelected)"
data-ng-options="blisterPackTemplate as blisterPackTemplate.name for blisterPackTemplate in blisterPackTemplates">
<option value="">Select Account</option>
</select>
{{itemList}}
</div>
</div>
js:
function ctrl($scope) {
$scope.itemList = [];
$scope.blisterPackTemplates = [{id:1,name:"a"},{id:2,name:"b"},{id:3,name:"c"}];
$scope.changedValue = function(item) {
$scope.itemList.push(item.name);
}
}

How do I select by partial string from a pandas DataFrame?
This post is meant for readers who want to
isin
)...and would like to know more about what methods should be preferred over others.
(P.S.: I've seen a lot of questions on similar topics, I thought it would be good to leave this here.)
Friendly disclaimer, this is post is long.
# setup
df1 = pd.DataFrame({'col': ['foo', 'foobar', 'bar', 'baz']})
df1
col
0 foo
1 foobar
2 bar
3 baz
str.contains
can be used to perform either substring searches or regex based search. The search defaults to regex-based unless you explicitly disable it.
Here is an example of regex-based search,
# find rows in `df1` which contain "foo" followed by something
df1[df1['col'].str.contains(r'foo(?!$)')]
col
1 foobar
Sometimes regex search is not required, so specify regex=False
to disable it.
#select all rows containing "foo"
df1[df1['col'].str.contains('foo', regex=False)]
# same as df1[df1['col'].str.contains('foo')] but faster.
col
0 foo
1 foobar
Performance wise, regex search is slower than substring search:
df2 = pd.concat([df1] * 1000, ignore_index=True)
%timeit df2[df2['col'].str.contains('foo')]
%timeit df2[df2['col'].str.contains('foo', regex=False)]
6.31 ms ± 126 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
2.8 ms ± 241 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
Avoid using regex-based search if you don't need it.
Addressing ValueError
s
Sometimes, performing a substring search and filtering on the result will result in
ValueError: cannot index with vector containing NA / NaN values
This is usually because of mixed data or NaNs in your object column,
s = pd.Series(['foo', 'foobar', np.nan, 'bar', 'baz', 123])
s.str.contains('foo|bar')
0 True
1 True
2 NaN
3 True
4 False
5 NaN
dtype: object
s[s.str.contains('foo|bar')]
# ---------------------------------------------------------------------------
# ValueError Traceback (most recent call last)
Anything that is not a string cannot have string methods applied on it, so the result is NaN (naturally). In this case, specify na=False
to ignore non-string data,
s.str.contains('foo|bar', na=False)
0 True
1 True
2 False
3 True
4 False
5 False
dtype: bool
How do I apply this to multiple columns at once?
The answer is in the question. Use DataFrame.apply
:
# `axis=1` tells `apply` to apply the lambda function column-wise.
df.apply(lambda col: col.str.contains('foo|bar', na=False), axis=1)
A B
0 True True
1 True False
2 False True
3 True False
4 False False
5 False False
All of the solutions below can be "applied" to multiple columns using the column-wise apply
method (which is OK in my book, as long as you don't have too many columns).
If you have a DataFrame with mixed columns and want to select only the object/string columns, take a look at select_dtypes
.
This is most easily achieved through a regex search using the regex OR pipe.
# Slightly modified example.
df4 = pd.DataFrame({'col': ['foo abc', 'foobar xyz', 'bar32', 'baz 45']})
df4
col
0 foo abc
1 foobar xyz
2 bar32
3 baz 45
df4[df4['col'].str.contains(r'foo|baz')]
col
0 foo abc
1 foobar xyz
3 baz 45
You can also create a list of terms, then join them:
terms = ['foo', 'baz']
df4[df4['col'].str.contains('|'.join(terms))]
col
0 foo abc
1 foobar xyz
3 baz 45
Sometimes, it is wise to escape your terms in case they have characters that can be interpreted as regex metacharacters. If your terms contain any of the following characters...
. ^ $ * + ? { } [ ] \ | ( )
Then, you'll need to use re.escape
to escape them:
import re
df4[df4['col'].str.contains('|'.join(map(re.escape, terms)))]
col
0 foo abc
1 foobar xyz
3 baz 45
re.escape
has the effect of escaping the special characters so they're treated literally.
re.escape(r'.foo^')
# '\\.foo\\^'
By default, the substring search searches for the specified substring/pattern regardless of whether it is full word or not. To only match full words, we will need to make use of regular expressions here—in particular, our pattern will need to specify word boundaries (\b
).
For example,
df3 = pd.DataFrame({'col': ['the sky is blue', 'bluejay by the window']})
df3
col
0 the sky is blue
1 bluejay by the window
Now consider,
df3[df3['col'].str.contains('blue')]
col
0 the sky is blue
1 bluejay by the window
v/s
df3[df3['col'].str.contains(r'\bblue\b')]
col
0 the sky is blue
Similar to the above, except we add a word boundary (\b
) to the joined pattern.
p = r'\b(?:{})\b'.format('|'.join(map(re.escape, terms)))
df4[df4['col'].str.contains(p)]
col
0 foo abc
3 baz 45
Where p
looks like this,
p
# '\\b(?:foo|baz)\\b'
Because you can! And you should! They are usually a little bit faster than string methods, because string methods are hard to vectorise and usually have loopy implementations.
Instead of,
df1[df1['col'].str.contains('foo', regex=False)]
Use the in
operator inside a list comp,
df1[['foo' in x for x in df1['col']]]
col
0 foo abc
1 foobar
Instead of,
regex_pattern = r'foo(?!$)'
df1[df1['col'].str.contains(regex_pattern)]
Use re.compile
(to cache your regex) + Pattern.search
inside a list comp,
p = re.compile(regex_pattern, flags=re.IGNORECASE)
df1[[bool(p.search(x)) for x in df1['col']]]
col
1 foobar
If "col" has NaNs, then instead of
df1[df1['col'].str.contains(regex_pattern, na=False)]
Use,
def try_search(p, x):
try:
return bool(p.search(x))
except TypeError:
return False
p = re.compile(regex_pattern)
df1[[try_search(p, x) for x in df1['col']]]
col
1 foobar
np.char.find
, np.vectorize
, DataFrame.query
.In addition to str.contains
and list comprehensions, you can also use the following alternatives.
np.char.find
Supports substring searches (read: no regex) only.
df4[np.char.find(df4['col'].values.astype(str), 'foo') > -1]
col
0 foo abc
1 foobar xyz
np.vectorize
This is a wrapper around a loop, but with lesser overhead than most pandas str
methods.
f = np.vectorize(lambda haystack, needle: needle in haystack)
f(df1['col'], 'foo')
# array([ True, True, False, False])
df1[f(df1['col'], 'foo')]
col
0 foo abc
1 foobar
Regex solutions possible:
regex_pattern = r'foo(?!$)'
p = re.compile(regex_pattern)
f = np.vectorize(lambda x: pd.notna(x) and bool(p.search(x)))
df1[f(df1['col'])]
col
1 foobar
DataFrame.query
Supports string methods through the python engine. This offers no visible performance benefits, but is nonetheless useful to know if you need to dynamically generate your queries.
df1.query('col.str.contains("foo")', engine='python')
col
0 foo
1 foobar
More information on query
and eval
family of methods can be found at Dynamic Expression Evaluation in pandas using pd.eval().
str.contains
, for its simplicity and ease handling NaNs and mixed datanp.vectorize
df.query
I'd recommend using a regular expressions instead of string operations for this:
Set fso = CreateObject("Scripting.FileSystemObject")
filename = "C:\VBS\filediprova.txt"
newtext = vbLf & "<tr><td><a href=""..."">Beginning_of_DD_TC5</a></td></tr>"
Set re = New RegExp
re.Pattern = "(\n.*?Test Case \d)"
re.Global = False
re.IgnoreCase = True
text = f.OpenTextFile(filename).ReadAll
f.OpenTextFile(filename, 2).Write re.Replace(text, newText & "$1")
The regular expression will match a line feed (\n
) followed by a line containing the string Test Case
followed by a number (\d
), and the replacement will prepend that with the text you want to insert (variable newtext
). Setting re.Global = False
makes the replacement stop after the first match.
If the line breaks in your text file are encoded as CR-LF
(carriage return + line feed) you'll have to change \n
into \r\n
and vbLf
into vbCrLf
.
If you have to modify several text files, you could do it in a loop like this:
For Each f In fso.GetFolder("C:\VBS").Files
If LCase(fso.GetExtensionName(f.Name)) = "txt" Then
text = f.OpenAsTextStream.ReadAll
f.OpenAsTextStream(2).Write re.Replace(text, newText & "$1")
End If
Next
You're looking for unset()
.
But take into account that you can't explicitly destroy an object.
It will stay there, however if you unset the object and your script pushes PHP to the memory limits the objects not needed will be garbage collected. I would go with unset()
(as opposed to setting it to null) as it seems to have better performance (not tested but documented on one of the comments from the PHP official manual).
That said, do keep in mind that PHP always destroys the objects as soon as the page is served. So this should only be needed on really long loops and/or heavy intensive pages.
While calling/invoking your programme you can use this command : java [-options] className [args...]
in place of [-options] provide more memory e.g -Xmx1024m or more. but this is just a workaround, u have to change ur parsing mechanism.
Check your line endings! If you see an error about the file not being found, followed by this "premature of end headers" error in your Apache log - it may be that you have Windows line endings in your script in instead of Unix style. I ran into that problem / solution.
Why not Process.Start(@"c:\test");
?
Solution:
Step1: Uncomment the php_curl.dll from php.ini
Step2: Copy the following three files from php installed directory.i.e "C:\\php7".
libeay32.dll,
libssh2.dll,
ssleay32.dll
Step3: Paste the files under two place
httpd.conf's ServerRoot directive. i.e "C\Apache24"
apache bin directory. i.e "C\Apache24\bin"
Step4: Restart apache.
That's all. I solve the problem by this way.Hope it might work for you.
The solution is given here. https://abcofcomputing.blogspot.com/2017/06/php7-unable-to-load-phpcurldll.html

Use chown
to change ownership and chmod
to change rights.
use the -R
option to apply the rights for all files inside of a directory too.
Note that both these commands just work for directories too. The -R
option makes them also change the permissions for all files and directories inside of the directory.
For example
sudo chown -R username:group directory
will change ownership (both user and group) of all files and directories inside of directory and directory itself.
sudo chown username:group directory
will only change the permission of the folder directory but will leave the files and folders inside the directory alone.
you need to use sudo to change the ownership from root to yourself.
Edit:
Note that if you use chown user: file
(Note the left-out group), it will use the default group for that user.
Also You can change the group ownership of a file or directory with the command:
chgrp group_name file/directory_name
You must be a member of the group to which you are changing ownership to.
You can find group of file as follows
# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file
# chown sujit:friends file
User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.
What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.
But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.
Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.
Look for the official 2.7 setuptools installer (which contains easy_install). You only need to install from sources for windows 64 bits.
If you are grepping through a git repository, I'd recommend you use git grep
. You don't need to pass in -R
or the path.
git grep pattern
That will show all matches from your current directory down.
The only subquery appears to be this - try adding a ROWNUM
limit to the where to be sure:
(SELECT C.I_WORKDATE
FROM T_COMPENSATION C
WHERE C.I_COMPENSATEDDATE = A.I_REQDATE AND ROWNUM <= 1
AND C.I_EMPID = A.I_EMPID)
You do need to investigate why this isn't unique, however - e.g. the employee might have had more than one C.I_COMPENSATEDDATE
on the matched date.
For performance reasons, you should also see if the lookup subquery can be rearranged into an inner / left join, i.e.
SELECT
...
REPLACE(TO_CHAR(C.I_WORKDATE, 'DD-Mon-YYYY'),
' ',
'') AS WORKDATE,
...
INNER JOIN T_EMPLOYEE_MS E
...
LEFT OUTER JOIN T_COMPENSATION C
ON C.I_COMPENSATEDDATE = A.I_REQDATE
AND C.I_EMPID = A.I_EMPID
...

// This will output the full path where the file will be written to...
System.out.println(logFile.getCanonicalPath());
writer = new BufferedWriter(new FileWriter(logFile));
writer.write("Hello world!");
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
// Close the writer regardless of what happens...
writer.close();
} catch (Exception e) {
}
}
}
}
Also note that your example will overwrite any existing files. If you want to append the text to the file you should do the following instead:
writer = new BufferedWriter(new FileWriter(logFile, true));
I had a problem like this whereby I had specified the width of my Window, but had the height set to Auto
. The child DockPanel
had it's VerticalAlignment
set to Top and the Window had it's VerticalContentAlignment set to Top, yet the Window would still be much taller than the contents.
Using Snoop, I discovered that the ContentPresenter
within the Window (part of the Window, not something I had put there) has it's VerticalAlignment
set to Stretch
and can't be changed without retemplating the entire Window!
After a lot of frustration, I discovered the SizeToContent
property - you can use this to specify whether you want the Window to size vertically, horizontally or both, according to the size of the contents - everything is sizing nicely now, I just can't believe it took me so long to find that property!
We pull in content frequently from our CMS as [innerHTML]="content.title"
. We place the necessary classes in the application's root styles.scss
file rather than in the component's scss file. Our CMS purposely strips out in-line styles so we must have prepared classes that the author can use in their content. Remember using {{content.title}}
in the template will not render html from the content.
why not keep it simple
cd SOME_PATH && run_some_command && cd -
the last 'cd' command will take you back to the last pwd directory. This should work on all *nix systems.
This will clear 25 new lines:
def clear():
print(' \n' * 25)
clear()
I use eclipse with pydev. I like the newline solution better than the for num in range . The for loop throws warnings, while the print newline doesn't. If you want to specify the number of newlines in the clear statement try this variation.
def clear(j):
print(' \n' * j)
clear(25)
Unfortunately, the iOS Simulator app does not support saving videos. The easiest thing to do is use Quicktime Player to make a screen recording. Of course, you'll see the mouse interacting with it which is not what you want, but I don't have a better option for you at this time.
Reason is as @MilicaMedic says. Alternative solution is disable all constraints, do the update and then enable the constraints again like this. Very useful when updating test data in test environments.
exec sp_MSforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"
update patient set id_no='7008255601088' where id_no='8008255601088'
update patient_address set id_no='7008255601088' where id_no='8008255601088'
exec sp_MSforeachtable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"

If you have a table called memos that has two columns id
and text
you should be able to do like this:
INSERT INTO memos(id,text)
SELECT 5, 'text to insert'
WHERE NOT EXISTS(SELECT 1 FROM memos WHERE id = 5 AND text = 'text to insert');
If a record already contains a row where text
is equal to 'text to insert' and id
is equal to 5, then the insert operation will be ignored.
I don't know if this will work for your particular query, but perhaps it give you a hint on how to proceed.
I would advice that you instead design your table so that no duplicates are allowed as explained in @CLs answer
below.
I had the same problem, and all the solutions from SO or Google didn't work for me. Usually, setNeedsDisplay
does work, but when it doesn't...
I've tried calling setNeedsDisplay
of the view just every possible way from every possible threads and stuff - still no success. We know, as Rob said, that
"this needs to be drawn in the next draw cycle."
But for some reason it wouldn't draw this time. And the only solution I've found is calling it manually after some time, to let anything that blocks the draw pass away, like this:
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW,
(int64_t)(0.005 * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void) {
[viewToRefresh setNeedsDisplay];
});
It's a good solution if you don't need the view to redraw really often. Otherwise, if you're doing some moving (action) stuff, there is usually no problems with just calling setNeedsDisplay
.
I hope it will help someone who is lost there, like I was.
I was able to get it to work in IE and FF with jQuery's:
$(window).bind('beforeunload', function(){
});
instead of: unload, onunload, or onbeforeunload
Try this
npm uninstall angular-cli
npm install @angular/cli --save-dev
Today I faced with this problem. I used Android Studio 2.1.3, windows 10. While debugging it works fine, but if I update to release mode it does not work. I cleared all proguard conditions, updated, but this was not solution.
The solution is related with project structure. The google_maps_api.xml file was different between app\src\debug\res and app\src\release\res. I did manual copy paste from debug to release folder.
Now it works.
You can size your label according to text and other related controls using two ways-
For iOS 7.0 and above
CGSize labelTextSize = [labelText boundingRectWithSize:CGSizeMake(labelsWidth, MAXFLOAT)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:@{
NSFontAttributeName : labelFont
}
context:nil].size;
before iOS 7.0 this could be used to calculate label size
CGSize labelTextSize = [label.text sizeWithFont:label.font
constrainedToSize:CGSizeMake(label.frame.size.width, MAXFLOAT)
lineBreakMode:NSLineBreakByWordWrapping];
// reframe other controls based on labelTextHeight
CGFloat labelTextHeight = labelTextSize.height;
If you do not want to calculate the size of the label's text than you can use -sizeToFit on the instance of UILabel as-
[label setNumberOfLines:0]; // for multiline label
[label setText:@"label text to set"];
[label sizeToFit];// call this to fit size of the label according to text
// after this you can get the label frame to reframe other related controls
Turns out it is possible to enter a host name directly into the playbook, so running the playbook with hosts: imac-2.local
will work fine. But it's kind of clunky.
A better solution might be defining the playbook's hosts using a variable, then passing in a specific host address via --extra-vars
:
# file: user.yml (playbook)
---
- hosts: '{{ target }}'
user: ...
Running the playbook:
ansible-playbook user.yml --extra-vars "target=imac-2.local"
If {{ target }}
isn't defined, the playbook does nothing. A group from the hosts file can also be passed through if need be. Overall, this seems like a much safer way to construct a potentially destructive playbook.
Playbook targeting a single host:
$ ansible-playbook user.yml --extra-vars "target=imac-2.local" --list-hosts
playbook: user.yml
play #1 (imac-2.local): host count=1
imac-2.local
Playbook with a group of hosts:
$ ansible-playbook user.yml --extra-vars "target=office" --list-hosts
playbook: user.yml
play #1 (office): host count=3
imac-1.local
imac-2.local
imac-3.local
Forgetting to define hosts is safe!
$ ansible-playbook user.yml --list-hosts
playbook: user.yml
play #1 ({{target}}): host count=0
If you have not pushed the code to your remote branch (GitHub/Bitbucket) you can change the commit message on the command line as below.
git commit --amend -m "Your new message"
If you're working on a specific branch, do this:
git commit --amend -m "BRANCH-NAME: new message"
If you've already pushed the code with a wrong message then you need to be careful when changing the message. i.e after you change the commit message and try pushing it again you end up with having issues. To make it smooth follow the following steps.
Please read the entire answer before doing it
git commit --amend -m "BRANCH-NAME : your new message"
git push -f origin BRANCH-NAME # Not a best practice. Read below why?
Important note: When you use the force push directly you might end up with code issues that other developers are working on the same branch. So to avoid those conflicts you need to pull the code from your branch before making the force push:
git commit --amend -m "BRANCH-NAME : your new message"
git pull origin BRANCH-NAME
git push -f origin BRANCH-NAME
This is the best practice when changing the commit message, if it was already pushed.
Well, it's too late to post an answer, but I feel my explanation will be easy to understand for beginners with Angular. The following is one of the examples that I give during my presentation.
Consider your angular Application as a building. A building can have N
number of apartments in it. An apartment is considered as a module. An Apartment can then have N
number of rooms which correspond to the building blocks of an Angular application named components.
Now each apartment (Module)` will have rooms (Components), lifts (Services) to enable larger movement in and out the apartments, wires (Pipes) to transform around and make it useful in the apartments.
You will also have places like swimming pool, tennis court which are being shared by all building residents. So these can be considered as components inside SharedModule.
Basically, the difference is as follows,
Follow my slides to understand the building blocks of an Angular application
Here is my session on Building Blocks of Angular for beginners
While using a std::map
is fine or using a 256-sized char table would be fine, you could save yourself an enormous amount of space agony by simply using an enum
. If you have C++11 features, you can use enum class
for strong-typing:
// First, we define base-pairs. Because regular enums
// Pollute the global namespace, I'm using "enum class".
enum class BasePair {
A,
T,
C,
G
};
// Let's cut out the nonsense and make this easy:
// A is 0, T is 1, C is 2, G is 3.
// These are indices into our table
// Now, everything can be so much easier
BasePair Complimentary[4] = {
T, // Compliment of A
A, // Compliment of T
G, // Compliment of C
C, // Compliment of G
};
Usage becomes simple:
int main (int argc, char* argv[] ) {
BasePair bp = BasePair::A;
BasePair complimentbp = Complimentary[(int)bp];
}
If this is too much for you, you can define some helpers to get human-readable ASCII characters and also to get the base pair compliment so you're not doing (int)
casts all the time:
BasePair Compliment ( BasePair bp ) {
return Complimentary[(int)bp]; // Move the pain here
}
// Define a conversion table somewhere in your program
char BasePairToChar[4] = { 'A', 'T', 'C', 'G' };
char ToCharacter ( BasePair bp ) {
return BasePairToChar[ (int)bp ];
}
It's clean, it's simple, and its efficient.
Now, suddenly, you don't have a 256 byte table. You're also not storing characters (1 byte each), and thus if you're writing this to a file, you can write 2 bits per Base pair instead of 1 byte (8 bits) per base pair. I had to work with Bioinformatics Files that stored data as 1 character each. The benefit is it was human-readable. The con is that what should have been a 250 MB file ended up taking 1 GB of space. Movement and storage and usage was a nightmare. Of coursse, 250 MB is being generous when accounting for even Worm DNA. No human is going to read through 1 GB worth of base pairs anyhow.
The problem was the box "open new connection" that was checked. So I couldn't use my temporary table.
UPDATE 2016: Somewhere between July 2015 and January 2016 the printing feature request that I wrote about in 2014 was removed. The original answer is below, with the relevant links changed to the latest working versions in the Web Archive:
Printing in Sublime Text is a feature that has been requested for about 4 years (as of 2014), with 1600+ supporting votes and 160+ comments in the discussion below. For something around 6000 feature requests this is in the top 5.
See the original, still open, feature request:
Judging from the feature request (still open with no official answer) it seems unlikely that printing will ever get implemented in version 3 (as others have suggested) or in any version at all.
The discussion below this feature request may give some insight on why printing is not supported and whether or not it has a chance to get supported in the future.
Maybe if more people vote or comment it will change in the future. (See Update 2016 below for an up-to-date list of feature requests)
Some workarounds were suggested, the most popular advices were to use some other editor for printing (eg. Brackets, Atom, gedit, Notepad++) or to use some 3rd party plugins that reportedly don't work well or at all.
In general there is a strong opposition to adding printing as a native feature of Sublime Text which for such a universal functionality among text editors seems surprising, but may nevertheless shed some light on this issue.
Meanwhile, there are many free editors that can print (in fact I cannot think of a single one that couldn't) so it is easy to use some other editor whenever a need for printing arises.
Since the feature request described above was removed (please comment if anyone knows why) here is an up-to-date list of some other places to find more info about printing in Sublime Text:
Since the original feature request #25170 was removed, you should vote and comment in the other feature requests about printing instead.
You can use this:
$("#id").click(function()
{
$(this).data('clicked', true);
});
Now check it via an if statement:
if($("#id").data('clicked'))
{
// code here
}
For more information you can visit the jQuery website on the .data() function.
In my case the issue was caused by the same name of target and folder inside a group.
Just rename conflicted file or folder to resolve the issue.
There's no way to initiate a file transfer back to/from local Windows from a SSH session opened in PuTTY window.
Though PuTTY supports connection-sharing.
While you still need to run a compatible file transfer client (pscp
or psftp
), no new login is required, it automatically (if enabled) makes use of an existing PuTTY session.
To enable the sharing see:
Sharing an SSH connection between PuTTY tools.
Even without connection-sharing, you can still use the psftp
or pscp
from Windows command line.
See How to use PSCP to copy file from Unix machine to Windows machine ...?
Note that the scp
is OpenSSH program. It's primarily *nix program, but you can run it via Windows Subsystem for Linux or get a Windows build from Win32-OpenSSH (it is already built-in in the latest versions of Windows 10).
If you really want to download the files to a local desktop, you have to specify a target path as %USERPROFILE%\Desktop
(what typically resolves to a path like C:\Users\username\Desktop
).
Alternative way is to use WinSCP, a GUI SFTP/SCP client. While you browse the remote site, you can anytime open SSH terminal to the same site using Open in PuTTY command.
See Opening Session in PuTTY.
With an additional setup, you can even make PuTTY automatically navigate to the same directory you are browsing with WinSCP.
See Opening PuTTY in the same directory.
(I'm the author of WinSCP)
This works fine if you want the http protocol also since it could be http or https.
$domainURL = $_SERVER['REQUEST_SCHEME']."://".$_SERVER['SERVER_NAME'];
My Solution in laravel 5.2
{{ Form::open(['route' => ['votes.submit', $video->id], 'method' => 'POST']) }}

You basically can loop over a Range
Get a sheet
myWs = (Worksheet)MyWb.Worksheets[1];
Get the Range you're interested in If you really want to check every cell use Excel's limits
The Excel 2007 "Big Grid" increases the maximum number of rows per worksheet from 65,536 to over 1 million, and the number of columns from 256 (IV) to 16,384 (XFD). from here http://msdn.microsoft.com/en-us/library/aa730921.aspx#Office2007excelPerf_BigGridIncreasedLimitsExcel
and then loop over the range
Range myBigRange = myWs.get_Range("A1", "A256");
string myValue;
foreach(Range myCell in myBigRange )
{
myValue = myCell.Value2.ToString();
}
Why answer a 6 year old question ?
One the most fundamental concepts working with any programming language is how to navigate from one (window, form or page) to another. Also while doing this navigation the developer often wants to pass data from one (window, form or page) and display or use the data passed
While most of the answers here provide good to excellent examples how to accomplish this we thought we would kick it up a notch or two or three
We said three because we will navigate between three (window, form or page) and use the concept of static variables to pass data around the (window, form or page)
We will also include some decision making code while we navigate

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH
. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:
export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH
Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).
var $div = $('#desiredDiv');
$div.contents().remove();
$div.html('<p>This is new HTML.</p>');
That should work just fine.
if we are talking about validations also why we have not checked for null string entries. Any specific reasons?
I think below way help since IsNullOrEmpty is a system defined method and ternary operators have cyclomatic complexity = 1 while if() {} else {} has value 2.
public static string Truncate(string input, int truncLength)
{
return (!String.IsNullOrEmpty(input) && input.Length >= truncLength)
? input.Substring(0, truncLength)
: input;
}
If a
is your array:
In [11]: a[:,:2]
Out[11]:
array([[-0.57098887, -0.4274751 ],
[-0.22279713, -0.51723555],
[ 0.67492385, -0.69294472],
[ 0.41086611, 0.26374238]])
Do you want to know if a type is the same type as int64_t or do you want to know if something is 64 bits? Based on your proposed solution, I think you're asking about the latter. In that case, I would do something like
template<typename T>
bool is_64bits() { return sizeof(T) * CHAR_BIT == 64; } // or >= 64
Running "Valgrind" can:
1) Help Identify Memory Leaks - show you how many memory leaks you have, and point out to the lines in the code where the leaked memory was allocated.
2) Point out wrong attempts to free memory (e.g. improper call of delete
)
Instructions for using "Valgrind"
1) Get valgrind here.
2) Compile your code with -g
flag
3) In your shell run:
valgrind --leak-check=yes myprog arg1 arg2
Where "myprog" is your compiled program and arg1
, arg2
your programme's arguments.
4) The result is a list of calls to malloc
/new
that did not have subsequent calls to free delete.
For example:
==4230== at 0x1B977DD0: malloc (vg_replace_malloc.c:136)
==4230== by 0x804990F: main (example.c:6)
Tells you in which line the malloc
(that was not freed) was called.
As Pointed out by others, make sure that for every new
/malloc
call, you have a subsequent delete
/free
call.
Here is the Hooks solution
import React, {useRef} from 'react';
const MyComponent = () =>{
const myRefname= useRef(null);
const handleClick = () => {
myRefname.current.focus();
}
return (
<div onClick={handleClick}>
<input ref={myRefname}/>
</div>
);
}
You could also use the CountDownLatch
object like explained here.
myArray.sample(x)
can also help you to get x random elements from the array.
A note for people who created the local copy on Windows and want to create a corresponding remote repository on a Unix-line system, where text files get LF endings on further clones by developers on Unix-like systems, but CRLF endings on Windows.
If you created your Windows repository before setting up line-ending translation then you have a problem. Git's default setting is no translation, so your working set uses CRLF but your repository (i.e. the data stored under .git) has saved the files as CRLF too.
When you push to the remote, the saved files are copied as-is, no line ending translation occurs. (Line ending translation occurs when files are commited to a repository, not when repositories are pushed). You end up with CRLF in your Unix-like repository, which is not what you want.
To get LF in the remote repository you have to make sure LF is in the local repository first, by re-normalizing your Windows repository. This will have no visible effect on your Windows working set, which still has CRLF endings, however when you push to remote, the remote will get LF correctly.
I'm not sure if there's an easy way to tell what line endings you have in your Windows repository - I guess you could test it by setting core.autocrlf=false and then cloning (If the repo has LF endings, the clone will have LF too).
int(limit)
returns the value converted into an integer, and doesn't change it in place as you call the function (which is what you are expecting it to).
Do this instead:
limit = int(limit)
Or when definiting limit
:
if 'limit' in user_data :
limit = int(user_data['limit'])
New installers (.msi downloaded from https://nodejs.org) have "Add to PATH" option. By default it is selected. Make sure that you leave it checked.
I use
android:screenOrientation="nosensor"
It is helpful if you do not want to support up side down portrait mode.
-w
is the GCC-wide option to disable warning messages.
C++11 allows you to do:
for (const auto& kv : myMap) {
std::cout << kv.first << " has value " << kv.second << std::endl;
}
C++17 allows you to do:
for (const auto& [key, value] : myMap) {
std::cout << key << " has value " << value << std::endl;
}
using structured binding.
UPDATE:
const auto is safer if you don't want to modify the map.
The 487 Response indicates that the previous request was terminated by user/application action. The most common occurrence is when the CANCEL happens as explained above. But it is also not limited to CANCEL. There are other cases where such responses can be relevant. So it depends on where you are seeing this behavior and whether its a user or application action that caused it.
15.1.2 UAS Behavior==> BYE Handling in RFC 3261
The UAS MUST still respond to any pending requests received for that dialog. It is RECOMMENDED that a 487 (Request Terminated) response be generated to those pending requests.
It's not clear what you're actually trying to achieve, but here are two alternatives:
class E
{
public:
struct X
{
int v;
};
// 1. (a) Instantiate an 'X' within 'E':
X x;
};
int main()
{
// 1. (b) Modify the 'x' within an 'E':
E e;
e.x.v = 9;
// 2. Instantiate an 'X' outside 'E':
E::X x;
x.v = 10;
}
I solved it with my own function. If you want to update specified field in document you need to address it clearly.
Example:
{
_id : ...,
some_key: {
param1 : "val1",
param2 : "val2",
param3 : "val3"
}
}
If you want to update param2 only, it's wrong to do:
db.collection.update( { _id:...} , { $set: { some_key : new_info } } //WRONG
You must use:
db.collection.update( { _id:...} , { $set: { some_key.param2 : new_info } }
So i wrote a function something like that:
function _update($id, $data, $options=array()){
$temp = array();
foreach($data as $key => $value)
{
$temp["some_key.".$key] = $value;
}
$collection->update(
array('_id' => $id),
array('$set' => $temp)
);
}
_update('1', array('param2' => 'some data'));
It prevents the browser from doing MIME-type sniffing. Most browsers are now respecting this header, including Chrome/Chromium, Edge, IE >= 8.0, Firefox >= 50 and Opera >= 13. See :
Sending the new X-Content-Type-Options response header with the value nosniff will prevent Internet Explorer from MIME-sniffing a response away from the declared content-type.
EDIT:
Oh and, that's an HTTP header, not a HTML meta tag option.

git pull
is really equivalent to running git fetch
and then git merge
. The git fetch
updates your so-called "remote-tracking branches" - typically these are ones that look like origin/master
, github/experiment
, etc. that you see with git branch -r
. These are like a cache of the state of branches in the remote repository that are updated when you do git fetch
(or a successful git push
).
So, suppose you've got a remote called origin
that refers to your GitHub repository, you would do:
git fetch origin
... and then do:
git diff master origin/master
... in order to see the difference between your master
, and the one on GitHub. If you're happy with those differences, you can merge them in with git merge origin/master
, assuming master
is your current branch.
Personally, I think that doing git fetch
and git merge
separately is generally a good idea.
As per the MySQL docs: http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_max_user_connections
maximum range: 4,294,967,295 (e.g. 2**32 - 1)
You'd probably run out of memory, file handles, and network sockets, on your server long before you got anywhere close to that limit.
let numericArray: number[] = [2, 3, 4, 1, 5, 8, 11];
let sortFn = (n1 , n2) => number { return n1 - n2; }
const sortedArray: number[] = numericArray.sort(sortFn);
Sort by some field:
let arr:{key:number}[] = [{key : 2}, {key : 3}, {key : 4}, {key : 1}, {key : 5}, {key : 8}, {key : 11}];
let sortFn2 = (obj1 , obj2) => {key:number} { return obj1.key - obj2.key; }
const sortedArray2:{key:number}[] = arr.sort(sortFn2);
To get the index
values as a list
/list
of tuple
s for Index
/MultiIndex
do:
df.index.values.tolist() # an ndarray method, you probably shouldn't depend on this
or
list(df.index.values) # this will always work in pandas
None of the methods listed scale the image to the largest possible size that fits in a box while retaining the desired aspect ratio.
This cannot be done with the IMG tag (at least not without a bit of JavaScript), but it can be done as follows:
<div style="background:center no-repeat url(...);background-size:contain;width:...;height:..."></div>

But till Laravel-4 you can use
{{ HTML::link('/auth/logout', 'Sign Out', array('class' => 'btn btn-default btn-flat')) }}
When comes to Laravel-5
{!! HTML::link('/auth/logout', 'Sign Out', array('class' => 'btn btn-default btn-flat')) !!}
You can also do this with the PHP function

go through the PHP document for the parameters of this function
I've put together a universal, drop-in UIScrollView
, UITableView
and even UICollectionView
subclass that takes care of moving all text fields within it out of the way of the keyboard.
When the keyboard is about to appear, the subclass will find the subview that's about to be edited, and adjust its frame and content offset to make sure that view is visible, with an animation to match the keyboard pop-up. When the keyboard disappears, it restores its prior size.
It should work with basically any setup, either a UITableView
-based interface, or one consisting of views placed manually.
Here' tis: solution for moving text fields out of the way of the keyboard
The changelog is sloppily worded. from __future__ import absolute_import
does not care about whether something is part of the standard library, and import string
will not always give you the standard-library module with absolute imports on.
from __future__ import absolute_import
means that if you import string
, Python will always look for a top-level string
module, rather than current_package.string
. However, it does not affect the logic Python uses to decide what file is the string
module. When you do
python pkg/script.py
pkg/script.py
doesn't look like part of a package to Python. Following the normal procedures, the pkg
directory is added to the path, and all .py
files in the pkg
directory look like top-level modules. import string
finds pkg/string.py
not because it's doing a relative import, but because pkg/string.py
appears to be the top-level module string
. The fact that this isn't the standard-library string
module doesn't come up.
To run the file as part of the pkg
package, you could do
python -m pkg.script
In this case, the pkg
directory will not be added to the path. However, the current directory will be added to the path.
You can also add some boilerplate to pkg/script.py
to make Python treat it as part of the pkg
package even when run as a file:
if __name__ == '__main__' and __package__ is None:
__package__ = 'pkg'
However, this won't affect sys.path
. You'll need some additional handling to remove the pkg
directory from the path, and if pkg
's parent directory isn't on the path, you'll need to stick that on the path too.

That's what worked for me.
Here is a rough explanation of the concepts.
[ACK]
is the acknowledgement that the previously sent data packet was received.
[FIN]
is sent by a host when it wants to terminate the connection; the TCP protocol requires both endpoints to send the termination request (i.e. FIN
).
So, suppose
[FIN,ACK]
indicating that it received the sent packet and wants to close the session.[FIN,ACK]
indicating that it received the termination request (the ACK
part) and that it too will close the connection (the FIN
part).However, if host A wants to close the session after sending the packet, it would only send a [FIN]
packet (nothing to acknowledge) but host B would respond with [FIN,ACK]
(acknowledges the request and responds with FIN
).
Finally, some TCP stacks perform half-duplex termination, meaning that they can send [RST]
instead of the usual [FIN,ACK]
. This happens when the host actively closes the session without processing all the data that was sent to it. Linux is one operating system which does just this.
You can find a more detailed and comprehensive explanation here.
data=np.genfromtxt(csv_file, delimiter=',', dtype='unicode')
It works fine for me.
OAuth 2.0 is a Security protocol. It is NEITHER an Authentication NOR an Authorization protocol.
Authentication by definition the answers two questions.
OAuth 2.0 has the following grant types
All 4 have one thing in common, access_token, an artifact that can be used to access protected resource.
The access_token does not provide the answer to the 2 questions that an "Authentication" protocol must answer.
An example to explain Oauth 2.0 (credits: OAuth 2 in Action, Manning publications)
Let's talk about chocolate. We can make many confections out of chocolate including, fudge, ice cream, and cake. But, none of these can be equated to chocolate because multiple other ingredients such as cream and bread are needed to make the confection, even though chocolate sounds like the main ingredient. Similarly, OAuth 2.0 is the chocolate, and cookies, TLS infrastucture, Identity Providers are other ingredients that are required to provide the "Authentication" functionality.
If you want Authentication, you may go for OpenID Connect, which provides an "id_token", apart from an access_token, that answers the questions that every authentication protocol must answer.
im currently watching a MVA python tutorial on youtube and noticed my intellisence had also disappeared, soon after they expalined why,
something along the lines of this (excuse my lack of proper coding vocabulary i am new to programming but i have found the solution)
Answer: " Visual studio can not always guess what you are trying to input - therefore it does not always realise that it needs to give you a hint, for example if you are trying to use a string within a variable and need intellisense to give you options for that strings content, you must sometime tell visual studio that this variable actually is a string.
example:
name = ' ' # insert this line to tell visual studio that your variable is a string.
name = input('whats your name? \n')
name = name.upper() #then when you type name.u.... it will give you intellisense
use rgba
(rgb with alpha transparency
):
border: 10px solid rgba(0,0,0,0.5); // 0.5 means 50% of opacity
The alpha transparency
variate between 0 (0% opacity = 100% transparent) and 1 (100 opacity = 0% transparent)
This is to show new line and return carriage in html, then you don't need to do it explicitly. You can do it in css by setting the white-space attribute pre-line value.
<span style="white-space: pre-line">@Model.CommentText</span>
What I believe you're looking for is a way to work with arrays as object values:
var o = {} // empty Object
var key = 'Orientation Sensor';
o[key] = []; // empty Array, which you can push() values into
var data = {
sampleTime: '1450632410296',
data: '76.36731:3.4651554:0.5665419'
};
var data2 = {
sampleTime: '1450632410296',
data: '78.15431:0.5247617:-0.20050584'
};
o[key].push(data);
o[key].push(data2);
This is standard JavaScript and not something NodeJS specific. In order to serialize it to a JSON string you can use the native JSON.stringify
:
JSON.stringify(o);
//> '{"Orientation Sensor":[{"sampleTime":"1450632410296","data":"76.36731:3.4651554:0.5665419"},{"sampleTime":"1450632410296","data":"78.15431:0.5247617:-0.20050584"}]}'
You can give https://github.com/ersiner/osx-env-sync a try. It handles both command line and GUI apps from a single source and works withe the latest version of OS X (Yosemite).
You can use path substitutions and other shell tricks since what you write is regular bash script to be sourced by bash in the first place. No restrictions.. (Check osx-env-sync documentation and you'll understand how it achieves this.)
I answered a similar question here where you'll find more.
The .selectedIndex
of the select
object has an index; you can use that to index into the .options
array.
I was able to resolve this problem by cleaning my assets cache:

Modulus division is pretty simple. It uses the remainder instead of the quotient.
1.0833... <-- Quotient
__
12|13
12
1 <-- Remainder
1.00 <-- Remainder can be used to find decimal values
.96
.040
.036
.0040 <-- remainder of 4 starts repeating here, so the quotient is 1.083333...
13/12 = 1R1, ergo 13%12 = 1.
It helps to think of modulus as a "cycle".
In other words, for the expression n % 12
, the result will always be < 12.
That means the sequence for the set 0..100
for n % 12
is:
{0,1,2,3,4,5,6,7,8,9,10,11,0,1,2,3,4,5,6,7,8,9,10,11,0,[...],4}
In that light, the modulus, as well as its uses, becomes much clearer.
What you are looking for is this:
SHOW VARIABLES;
You can modify it further like any query:
SHOW VARIABLES LIKE '%max%';

The method call System.runFinalizersOnExit(true) guarantees that finalizer methods are called before Java shuts down. However, this method is inherently unsafe and has been deprecated. An alternative is to add “shutdown hooks” with the method Runtime.addShutdownHook.

First of all, public static
non-final
fields are evil. Spring does not allow injecting to such fields for a reason.
Your workaround is valid, you don't even need getter/setter, private
field is enough. On the other hand try this:
@Value("${my.name}")
public void setPrivateName(String privateName) {
Sample.name = privateName;
}
(works with @Autowired
/@Resource
). But to give you some constructive advice: Create a second class with private
field and getter instead of public static
field.
I think this may solve your problem:
in config/application.rb:
config.autoload_paths << Rails.root.join('lib')
and keep the right naming convention in lib.
in lib/foo.rb:
class Foo
end
in lib/foo/bar.rb:
class Foo::Bar
end
if you really wanna do some monkey patches in file like lib/extensions.rb, you may manually require it:
in config/initializers/require.rb:
require "#{Rails.root}/lib/extensions"

HTML doesn't have a built-in editable dropdown list or combobox, but I implemented a mostly-CSS solution in an article.
You can see a full demo here but in summary, write HTML like this:
<span class="combobox withtextlist">
<input value="Fruit">
<span tabindex="-1" class="downarrow"></span>
<select size="10" class="sticky">
<option>Apple</option>
<option>Banana</option>
<option>Cherry</option>
<option>Dewberry</option>
</select>
</span>
And use CSS like this to style it (this is designed for both comboboxes, which have a down-arrow ? button, and dropdown menus which open when clicked and may be styled differently):
/* ------------------------------------------ */
/* ----- combobox / dropdown list styling */
/* ------------------------------------------ */
.combobox {
/* Border slightly darker than Chrome's <select>, slightly lighter than FireFox's */
border: 1px solid #999;
padding-right: 1.25em; /* leave room for ? */
}
.dropdown, .combobox {
/* "relative" and "inline-block" (or just "block") are needed
here so that "absolute" works correctly in children */
position: relative;
display: inline-block;
}
.combobox > .downarrow, .dropdown > .downarrow {
/* ? Outside normal flow, relative to container */
display: inline-block;
position: absolute;
top: 0;
bottom: 0;
right: 0;
width: 1.25em;
cursor: default;
nav-index: -1; /* nonfunctional in most browsers */
border-width: 0px; /* disable by default */
border-style: inherit; /* copy parent border */
border-color: inherit; /* copy parent border */
}
/* Add a divider before the ? down arrow in non-dropdown comboboxes */
.combobox:not(.dropdown) > .downarrow {
border-left-width: 1px;
}
/* Auto-down-arrow if one is not provided */
.downarrow:empty::before {
content: '?';
}
.downarrow::before, .downarrow > *:only-child {
text-align: center;
/* vertical centering trick */
position: relative;
top: 50%;
display: block; /* transform requires block/inline-block */
transform: translateY(-50%);

You also need some JavaScript to synchronize the list with the textbox:
function parentComboBox(el) {
for (el = el.parentNode; el != null && Array.prototype.indexOf.call(el.classList, "combobox") <= -1;)
el = el.parentNode;
return el;
}
// Uses jQuery
$(".combobox.withtextlist > select").change(function() {
var textbox = parentComboBox(this).firstElementChild;
textbox.value = this[this.selectedIndex].text;
});
$(".combobox.withtextlist > select").keypress(function(e) {
if (e.keyCode == 13) // Enter pressed
parentComboBox(this).firstElementChild.focus(); // Closes the popup
});
First, put this in your textview:
android:maxLines="10"
Then use \n
in the text of your textview.
maxLines makes the TextView be at most this many lines tall. You may choose another number :)
I face the same problem and solved by adding the JAVA_HOME variable with updated version of java in my Ubuntu Machine(16.04). if you are using "Apache Maven 3.3.9" You need to upgrade your JAVA_HOME with java7 or more
Step to Do this
1-sudo vim /etc/environment
2-JAVA_HOME=JAVA Installation Directory (MyCase-/opt/dev/jdk1.7.0_45/)
3-Run echo $JAVA_HOME will give the JAVA_HOME set value
4-Now mvn -version will give the desired output
Apache Maven 3.3.9
Maven home: /usr/share/maven
Java version: 1.7.0_45, vendor: Oracle Corporation
Java home: /opt/dev/jdk1.7.0_45/jre

sys.floatinfo(max=1.7976931348623157e+308, max_exp=1024, max_10_exp=308, min=2.2
250738585072014e-308, min_exp=-1021, min_10_exp=-307, dig=15, mant_dig=53, epsil
on=2.2204460492503131e-16, radix=2, rounds=1)
Specifically, sys.float_info.max
:
>>> sys.float_info.max
1.7976931348623157e+308
If that's not big enough, there's always positive infinity:
>>> infinity = float("inf")
>>> infinity
inf
>>> infinity / 10000
inf

The infix operator %>%
is not part of base R, but is in fact defined by the package magrittr
(CRAN) and is heavily used by dplyr
(CRAN).
It works like a pipe, hence the reference to Magritte's famous painting The Treachery of Images.
What the function does is to pass the left hand side of the operator to the first argument of the right hand side of the operator. In the following example, the data frame iris
gets passed to head()
:
library(magrittr)
iris %>% head()
Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1 5.1 3.5 1.4 0.2 setosa
2 4.9 3.0 1.4 0.2 setosa
3 4.7 3.2 1.3 0.2 setosa
4 4.6 3.1 1.5 0.2 setosa
5 5.0 3.6 1.4 0.2 setosa
6 5.4 3.9 1.7 0.4 setosa
Thus, iris %>% head()
is equivalent to head(iris)
.
Often, %>%
is called multiple times to "chain" functions together, which accomplishes the same result as nesting. For example in the chain below, iris
is passed to head()
, then the result of that is passed to summary()
.
iris %>% head() %>% summary()
Thus iris %>% head() %>% summary()
is equivalent to summary(head(iris))
. Some people prefer chaining to nesting because the functions applied can be read from left to right rather than from inside out.
The simplest way is to test whether a number is an integer is int(x) == x
. Otherwise, what David Heffernan said.

Creating .exe distributions isn't typical for Java. While such wrappers do exist, the normal mode of operation is to create a .jar file.
To create a .jar file from a Java project in Eclipse, use file->export->java->Jar file. This will create an archive with all your classes.
On the command prompt, use invocation like the following:
java -cp myapp.jar foo.bar.MyMainClass
Yes it is true.
If you create two instance of your class
Test t1 = new Test();
Test t2 = new Test();
Then t1.foo and t2.foo both synchronize on the same static object and hence block each other.
Your example wasn't working because you are trying to add 1 to a string that looks like this: "1.html". That will just get you this "1.html1" which is not what you want. You have to isolate the numeric part of the string and then convert it to an actual number before you can do math on it. After getting it to an actual number, you can then increase its value and then combine it back with the rest of the string.
You can use a custom replace function like this to isolate the various pieces of the original URL and replace the number with an incremented number:
function nextImage() {
return(window.location.href.replace(/(\d+)(\.html)$/, function(str, p1, p2) {
return((Number(p1) + 1) + p2);
}));
}
You can then call it like this:
window.location.href = nextImage();
Demo here: http://jsfiddle.net/jfriend00/3VPEq/
This will work for any URL that ends in some series of digits followed by .html and if you needed a slightly different URL form, you could just tweak the regular expression.
There's no supported way to do this, but won't you have to examine the files related to each installer to figure out how to actually install them after extracting them? Assuming you can spend the time to figure out which command-line applies, here are some candidate parameters that normally allow you to extract an installation.
MSI Based (may not result in a usable image for an InstallScript MSI installation):
setup.exe /a /s /v"/qn TARGETDIR=\"choose-a-location\""
or, to also extract prerequisites (for versions where it works),
setup.exe /a"choose-another-location" /s /v"/qn TARGETDIR=\"choose-a-location\""
InstallScript based:
setup.exe /s /extract_all
Suite based (may not be obvious how to install the resulting files):
setup.exe /silent /stage_only ISRootStagePath="choose-a-location"
you can join both tables even on UPDATE
statements,
UPDATE a
SET a.marks = b.marks
FROM tempDataView a
INNER JOIN tempData b
ON a.Name = b.Name
for faster performance, define an INDEX
on column marks
on both tables.
using SUBQUERY
UPDATE tempDataView
SET marks =
(
SELECT marks
FROM tempData b
WHERE tempDataView.Name = b.Name
)
Quoting from http://dev.mysql.com/doc/refman/5.1/en/create-table.html
{INDEX|KEY}
So KEY
is an INDEX
;)
Still relevant in 2018: don't install packages as admin.
The by far more sensible solution is to use virtualenv to create a virtual environment directory (virtualenv dirname
) and then activate that virtual environment with dirname\Script\Activate
in Windows before running any pip commands. Or use pipenv to manage the installs for you.
That way, everything gets written to dirs that you have full write permission for, without needing UAC, and without global installs for local directories.
I was very reluctant to choose the path I finally decide to take because of many answers. While they add more understanding to what is SQL and its principles, I decided to become an outlaw. I was also hesitant to post my findings as for some it's more important to vent frustration to someone breaking the rules rather than understanding that there are very few universal truthes.
I have tested it extensively and, in my specific case, it was way more efficient than both using array type (generously offered by PostgreSQL) or querying another table.
Here is my answer: I have successfully implemented a list into a single field in PostgreSQL, by making use of the fixed length of each item of the list. Let say each item is a color as an ARGB hex value, it means 8 char. So you can create your array of max 10 items by multiplying by the length of each item:
ALTER product ADD color varchar(80)
In case your list items length differ you can always fill the padding with \0
NB: Obviously this is not necessarily the best approach for hex number since a list of integers would consume less storage but this is just for the purpose of illustrating this idea of array by making use of a fixed length allocated to each item.
The reason why: 1/ Very convenient: retrieve item i at substring i*n, (i +1)*n. 2/ No overhead of cross tables queries. 3/ More efficient and cost-saving on the server side. The list is like a mini blob that the client will have to split.
While I respect people following rules, many explanations are very theoretical and often fail to acknowledge that, in some specific cases, especially when aiming for cost optimal with low-latency solutions, some minor tweaks are more than welcome.
"God forbid that it is violating some holy sacred principle of SQL": Adopting a more open-minded and pragmatic approach before reciting the rules is always the way to go. Else you might end up like a candid fanatic reciting the Three Laws of Robotics before being obliterated by Skynet
I don't pretend that this solution is a breakthrough, nor that it is ideal in term of readability and database flexibility, but it can certainly give you an edge when it comes to latency.
Quote:
Arrays of generic types are not allowed because they're not sound. The problem is due to the interaction of Java arrays, which are not statically sound but are dynamically checked, with generics, which are statically sound and not dynamically checked. Here is how you could exploit the loophole:
class Box<T> { final T x; Box(T x) { this.x = x; } } class Loophole { public static void main(String[] args) { Box<String>[] bsa = new Box<String>[3]; Object[] oa = bsa; oa[0] = new Box<Integer>(3); // error not caught by array store check String s = bsa[0].x; // BOOM! } }
We had proposed to resolve this problem using statically safe arrays (aka Variance) bute that was rejected for Tiger.

I had this problem when I had navigated from root TVC to TVC A then to TVC B. After tapping the "load" button in TVC B I wanted to jump straight back to the root TVC (no need to revisit TVC A so why do it). I had:
//Pop child from the nav controller
[self.navigationController popViewControllerAnimated:YES];
//Pop self to return to root
[self.navigationController popViewControllerAnimated:YES];
...which gave the error "Unbalanced calls to begin/end etc". The following fixed the error, but no animation:
//Pop child from the nav controller
[self.navigationController popViewControllerAnimated:NO];
//Then pop self to return to root
[self.navigationController popViewControllerAnimated:NO];
This was my final solution, no error and still animated:
//Pop child from the nav controller
[self.navigationController popViewControllerAnimated:NO];
//Then pop self to return to root, only works if first pop above is *not* animated
[self.navigationController popViewControllerAnimated:YES];

If you have to ask this question then you're probably unfamiliar with what most web applications/services do. You're probably thinking that all software do this:
user do an action
¦
v
application start processing action
+--> loop ...
+--> busy processing
end loop
+--> send result to user
However, this is not how web applications, or indeed any application with a database as the back-end, work. Web apps do this:
user do an action
¦
v
application start processing action
+--> make database request
+--> do nothing until request completes
request complete
+--> send result to user
In this scenario, the software spend most of its running time using 0% CPU time waiting for the database to return.
Multithreaded network apps handle the above workload like this:
request --> spawn thread
+--> wait for database request
+--> answer request
request --> spawn thread
+--> wait for database request
+--> answer request
request --> spawn thread
+--> wait for database request
+--> answer request
So the thread spend most of their time using 0% CPU waiting for the database to return data. While doing so they have had to allocate the memory required for a thread which includes a completely separate program stack for each thread etc. Also, they would have to start a thread which while is not as expensive as starting a full process is still not exactly cheap.
Since we spend most of our time using 0% CPU, why not run some code when we're not using CPU? That way, each request will still get the same amount of CPU time as multithreaded applications but we don't need to start a thread. So we do this:
request --> make database request
request --> make database request
request --> make database request
database request complete --> send response
database request complete --> send response
database request complete --> send response
In practice both approaches return data with roughly the same latency since it's the database response time that dominates the processing.
The main advantage here is that we don't need to spawn a new thread so we don't need to do lots and lots of malloc which would slow us down.
The seemingly mysterious thing is how both the approaches above manage to run workload in "parallel"? The answer is that the database is threaded. So our single-threaded app is actually leveraging the multi-threaded behaviour of another process: the database.
A singlethreaded app fails big if you need to do lots of CPU calculations before returning the data. Now, I don't mean a for loop processing the database result. That's still mostly O(n). What I mean is things like doing Fourier transform (mp3 encoding for example), ray tracing (3D rendering) etc.
Another pitfall of singlethreaded apps is that it will only utilise a single CPU core. So if you have a quad-core server (not uncommon nowdays) you're not using the other 3 cores.
A multithreaded app fails big if you need to allocate lots of RAM per thread. First, the RAM usage itself means you can't handle as many requests as a singlethreaded app. Worse, malloc is slow. Allocating lots and lots of objects (which is common for modern web frameworks) means we can potentially end up being slower than singlethreaded apps. This is where node.js usually win.
One use-case that end up making multithreaded worse is when you need to run another scripting language in your thread. First you usually need to malloc the entire runtime for that language, then you need to malloc the variables used by your script.
So if you're writing network apps in C or go or java then the overhead of threading will usually not be too bad. If you're writing a C web server to serve PHP or Ruby then it's very easy to write a faster server in javascript or Ruby or Python.
Some web servers use a hybrid approach. Nginx and Apache2 for example implement their network processing code as a thread pool of event loops. Each thread runs an event loop simultaneously processing requests single-threaded but requests are load-balanced among multiple threads.
Some single-threaded architectures also use a hybrid approach. Instead of launching multiple threads from a single process you can launch multiple applications - for example, 4 node.js servers on a quad-core machine. Then you use a load balancer to spread the workload amongst the processes.
In effect the two approaches are technically identical mirror-images of each other.

mysql5.58 unstart server in mac os 10.6.5
I just installed MySQL 5.5.8 (mysql-5.5.8-osx10.6-x86_64.dmg) on Mac os X 10.6.5 and also had the problem that MySQL was not starting.
After reading this post: http://forums.mysql.com/read.php?11,399397,399606#msg-399606 and editing the file as suggested everything started working.
I also did
sudo chown -R root:wheel /Library/StartupItems/MySQLCOM

In pymongo you can update with:
mycollection.update({'_id':mongo_id}, {"$set": post}, upsert=False)
Upsert parameter will insert instead of updating if the post is not found in the database.
Documentation is available at mongodb site.
UPDATE For version > 3 use update_one instead of update:
mycollection.update_one({'_id':mongo_id}, {"$set": post}, upsert=False)
You have a pointer to an object. Therefore, you need to access a field of an object that's pointed to by the pointer. To dereference the pointer you use *
, and to access a field, you use .
, so you can use:
cout << (*kwadrat).val1;
Note that the parentheses are necessary. This operation is common enough that long ago (when C was young) they decided to create a "shorthand" method of doing it:
cout << kwadrat->val1;
These are defined to be identical. As you can see, the ->
basically just combines a *
and a .
into a single operation. If you were dealing directly with an object or a reference to an object, you'd be able to use the .
without dereferencing a pointer first:
Kwadrat kwadrat2(2,3,4);
cout << kwadrat2.val1;
The ::
is the scope resolution operator. It is used when you only need to qualify the name, but you're not dealing with an individual object at all. This would be primarily to access a static data member:
struct something {
static int x; // this only declares `something::x`. Often found in a header
};
int something::x; // this defines `something::x`. Usually in .cpp/.cc/.C file.
In this case, since x
is static
, it's not associated with any particular instance of something
. In fact, it will exist even if no instance of that type of object has been created. In this case, we can access it with the scope resolution operator:
something::x = 10;
std::cout << something::x;
Note, however, that it's also permitted to access a static member as if it was a member of a particular object:
something s;
s.x = 1;
At least if memory serves, early in the history of C++ this wasn't allowed, but the meaning is unambiguous, so they decided to allow it.
Custom SerDe might be a way to do it. Or you could use some kind of mediation process with regex_replace:
create table tableB as
select
columnA
regexp_replace(description, '\\t', '') as description
from tableA
;
the refer link is like this:
exports = module.exports = function(){
//....
}
the properties of exports
or module.exports
,such as functions or variables , will be exposed outside
there is something you must pay more attention : don't override
exports .
why ?
because exports just the reference of module.exports , you can add the properties onto the exports ,but if you override the exports , the reference link will be broken .
good example :
exports.name = 'william';
exports.getName = function(){
console.log(this.name);
}
bad example :
exports = 'william';
exports = function(){
//...
}
If you just want to exposed only one function or variable , like this:
// test.js
var name = 'william';
module.exports = function(){
console.log(name);
}
// index.js
var test = require('./test');
test();
this module only exposed one function and the property of name is private for the outside .

Originally, I tried using EASendMail from the nugent package manager, only to realize that it’s a pay for version with 30-day trial. Don’t waist your time with it unless you plan on buying it. I noticed the program ran much faster using EASendMail, but for me, free trumped fast.
Just my 2 cents worth.
I ran into the same situation where commands such as git diff origin
or git diff origin master
produced the error reported in the question, namely Fatal: ambiguous argument...
To resolve the situation, I ran the command
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/master
to set refs/remotes/origin/HEAD to point to the origin/master branch.
Before running this command, the output of git branch -a
was:
* master
remotes/origin/master
After running the command, the error no longer happened and the output of git branch -a
was:
* master
remotes/origin/HEAD -> origin/master
remotes/origin/master
(Other answers have already identified that the source of the error is HEAD not being set for origin. But I thought it helpful to provide a command which may be used to fix the error in question, although it may be obvious to some users.)
Additional information:
For anybody inclined to experiment and go back and forth between setting and unsetting refs/remotes/origin/HEAD, here are some examples.
To unset:
git remote set-head origin --delete
To set:
(additional ways, besides the way shown at the start of this answer)
git remote set-head origin master
to set origin/head explicitly
OR
git remote set-head origin --auto
to query the remote and automatically set origin/HEAD to the remote's current branch.

You are asking for the condition where all the conditions are true, so len of the frame is the answer, unless I misunderstand what you are asking

This does not want to be a "just-use-a-library" answer but just in case you're using Lodash you can use .clamp
:
_.clamp(yourInput, lowerBound, upperBound);
So that:
_.clamp(22, -10, 10); // => 10
Here is its implementation, taken from Lodash source:
/**
* The base implementation of `_.clamp` which doesn't coerce arguments.
*
* @private
* @param {number} number The number to clamp.
* @param {number} [lower] The lower bound.
* @param {number} upper The upper bound.
* @returns {number} Returns the clamped number.
*/
function baseClamp(number, lower, upper) {
if (number === number) {
if (upper !== undefined) {
number = number <= upper ? number : upper;
}
if (lower !== undefined) {
number = number >= lower ? number : lower;
}
}
return number;
}
Also, it's worth noting that Lodash makes single methods available as standalone modules, so in case you need only this method, you can install it without the rest of the library:
npm i --save lodash.clamp
There are lot of GUI designers even like Eclipse plugins, just few of them could use both, Swing and SWT..
WindowBuilder Pro GUI Designer - eclipse marketplace
WindowBuilder Pro GUI Designer - Google code home page
and
Jigloo SWT/Swing GUI Builder - eclipse market place
Jigloo SWT/Swing GUI Builder - home page
The window builder is quite better tool..
But IMHO, GUIs created by those tools have really ugly and unmanageable code..
The PHP solution, in backend:
$string = `UPPERCASE`
$lowercase = strtolower($string);
echo ucwords($lowercase);
\n --> newline character is not working for inserting a new line.
str="Hello!!";
document.write(str);
document.write("\n");
document.write(str);
But if we use below code then it works fine and it gives new line.
document.write(str);
document.write("<br>");
document.write(str);
Note:: I tried in Visual Studio Code.
Try this:
DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);
int day = datePicker.getDayOfMonth();
int month = datePicker.getMonth() + 1;
int year = datePicker.getYear();
Step 1 Write all file SHA1s to a text file:
git rev-list --objects --all | sort -k 2 > allfileshas.txt
Step 2 Sort the blobs from biggest to smallest and write results to text file:
git gc && git verify-pack -v .git/objects/pack/pack-*.idx | egrep "^\w+ blob\W+[0-9]+ [0-9]+ [0-9]+$" | sort -k 3 -n -r > bigobjects.txt
Step 3a Combine both text files to get file name/sha1/size information:
for SHA in `cut -f 1 -d\ < bigobjects.txt`; do
echo $(grep $SHA bigobjects.txt) $(grep $SHA allfileshas.txt) | awk '{print $1,$3,$7}' >> bigtosmall.txt
done;
Step 3b If you have file names or path names containing spaces try this variation of Step 3a. It uses cut
instead of awk
to get the desired columns incl. spaces from column 7 to end of line:
for SHA in `cut -f 1 -d\ < bigobjects.txt`; do
echo $(grep $SHA bigobjects.txt) $(grep $SHA allfileshas.txt) | cut -d ' ' -f'1,3,7-' >> bigtosmall.txt
done;
Now you can look at the file bigtosmall.txt in order to decide which files you want to remove from your Git history.
Step 4 To perform the removal (note this part is slow since it's going to examine every commit in your history for data about the file you identified):
git filter-branch --tree-filter 'rm -f myLargeFile.log' HEAD

Steps 1-3a were copied from Finding and Purging Big Files From Git History

You can get the random number through urandom
head -200 /dev/urandom | cksum
Output:
3310670062 52870
To retrieve the one part of the above number.
head -200 /dev/urandom | cksum | cut -f1 -d " "
Then the output is
3310670062
To meet your requirement,
head -200 /dev/urandom |cksum | cut -f1 -d " " | awk '{print $1%63000+2001}'
You are also able to set some XSS related HTTP response headers via header(...)
X-XSS-Protection "1; mode=block"
to be sure, the browser XSS protection mode is enabled.
Content-Security-Policy "default-src 'self'; ..."
to enable browser-side content security. See this one for Content Security Policy (CSP) details: http://content-security-policy.com/ Especially setting up CSP to block inline-scripts and external script sources is helpful against XSS.
for a general bunch of useful HTTP response headers concerning the security of you webapp, look at OWASP: https://www.owasp.org/index.php/List_of_useful_HTTP_headers
You need to drag the EditText
from the edge of the layout and not just the other widget. You can also add constraints by just dragging the constraint point that surrounds the widget to the edge of the screen to add constraints as specified.
The modified code will look something similar to this:
app:layout_constraintLeft_toLeftOf="@+id/router_text"
app:layout_constraintTop_toTopOf="@+id/activity_main"
android:layout_marginTop="320dp"
app:layout_constraintBottom_toBottomOf="@+id/activity_main"
android:layout_marginBottom="16dp"
app:layout_constraintVertical_bias="0.29"
Don't forget to call sizeToFit()
after you change image if you then use size of UIImageView to set UIScrollView contentSize and/or compute zoom scale
let image = UIImage(named: "testImage")
imageView.image = image
imageView.sizeToFit()
scrollView.contentSize = imageView.bounds.size
This is not the best practice in .NET framework (4 & +) to check equality
String.Compare(x.Username, (string)drUser["Username"],
StringComparison.OrdinalIgnoreCase) == 0
Use the following instead
String.Equals(x.Username, (string)drUser["Username"],
StringComparison.OrdinalIgnoreCase)
- Use an overload of the String.Equals method to test whether two strings are equal.
- Use the String.Compare and String.CompareTo methods to sort strings, not to check for equality.
Most likely, you need to have the Javascript served over SSL.

Use this syntax for VB.NET 2005/2008 compatibility:
Dim theVar As New List(Of String)(New String() {"one", "two", "three"})
Although the VB.NET 2010 syntax is prettier.
You can use filter() to do that:
var tableRow = $("td").filter(function() {
return $(this).text() == "foo";
}).closest("tr");
There seems to be a really easy solution when dealing with data type issues.
Basically, at the end of Excel connection string, add ;IMEX=1;"
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\YOURSERVER\shared\Client Projects\FOLDER\Data\FILE.xls;Extended Properties="EXCEL 8.0;HDR=YES;IMEX=1";
This will resolve data type issues such as columns where values are mixed with text and numbers.
To get to connection property, right click on Excel connection manager below control flow and hit properties. It'll be to the right under solution explorer. Hope that helps.
Well the answer from @sahhhm didn't work for me, what i needed was to trigger the backKey from a custom button so what I did was I simply called,
backAction.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
MyRides.super.onBackPressed();
}
});
and it work like charm. Hope it will help others too.
SELECT
DATE_FORMAT(demo.dateFrom, '%e.%M.%Y') as dateFrom,
DATE_FORMAT(demo.dateUntil, '%e.%M.%Y') as dateUntil
FROM demo
If you dont want to change every function in your PHP code, to show the expected date format, change it at the source - your database.
It is important to name the rows with the as operator as in the example above (as dateFrom, as dateUntil). The names you write there are the names, the rows will be called in your result.
The output of this example will be
[Day of the month, numeric (0..31)].[Month name (January..December)].[Year, numeric, four digits]
Example: 5.August.2015
Change the dots with the separator of choice and check the DATE_FORMAT(date,format) function for more date formats.
first configure routing
import {RouteConfig, Router, ROUTER_DIRECTIVES} from 'angular2/router';
and
@RouteConfig([
{ path: '/addDisplay', component: AddDisplay, as: 'addDisplay' },
{ path: '/<secondComponent>', component: '<secondComponentName>', as: 'secondComponentAs' },
])
then in your component import and then inject Router
import {Router} from 'angular2/router'
export class AddDisplay {
constructor(private router: Router)
}
the last thing you have to do is to call
this.router.navigateByUrl('<pathDefinedInRouteConfig>');
or
this.router.navigate(['<aliasInRouteConfig>']);
The variable pCv is of type VARCHAR2 so when you concat the insert you aren't putting it inside single quotes:
EXECUTE IMMEDIATE 'INSERT INTO M'||pNum||'GR (CV, SUP, IDM'||pNum||') VALUES('''||pCv||''', '||pSup||', '||pIdM||')';
Additionally the error ORA-06512 raise when you are trying to insert a value too large in a column. Check the definiton of the table M_pNum_GR and the parameters that you are sending. Just for clarify if you try to insert the value 100 on a NUMERIC(2) field the error will raise.
As per the docs select, the following piece of code worked for me.
<div ng-controller="ExampleController">
<form name="myForm">
<label for="mySelect">Make a choice:</label>
<select name="mySelect" id="mySelect"
ng-options="option.name for option in data.availableOptions track by option.id"
ng-model="data.selectedOption"></select>
</form>
<hr>
<tt>option = {{data.selectedOption}}</tt><br/>
</div>
You can use strftime to help you format your date.
E.g.,
import datetime
t = datetime.datetime(2012, 2, 23, 0, 0)
t.strftime('%m/%d/%Y')
will yield:
'02/23/2012'
More information about formatting see here
Assuming that your markup looks like:
<div id="header" style="position: fixed;"></div>
<div id="content" style="position: relative;"></div>
Now both elements are positioned; in which case, the element at the bottom (in source order) will cover element above it (in source order).
Add a z-index
on header; 1
should be sufficient.
This is another possible solution:
et.append("");
Just try this solution if it doesn't work for any reason:
et.setSelection(et.getText().length());
