Here's an "optimized" version of your regex:
^011(9[976]\d|8[987530]\d|6[987]\d|5[90]\d|42\d|3[875]\d|
2[98654321]\d|9[8543210]|8[6421]|6[6543210]|5[87654321]|
4[987654310]|3[9643210]|2[70]|7|1)\d{0,14}$
You can replace the \d
s with [0-9]
if your regex syntax doesn't support \d
.
Proximity Sensor Dial
*#*#7378423#*#*
1) Service Tests - (If present)
2) Proximity Switch
3) Test on sensor (Next to logo(top) of mobile)
4) Yes if works, then u can keep on and proximity switch forever which gives beep all the time and consumes lot of battery
OR
4) No it doesn't work - Then simply clean the mobile screen or screen guard and clear the blocked screen from sensor. It works charm.
Technically, Its not any software solution, but hardware solution will work.
Merging the answers of @Cristian Radu and @Craig Mellon, and the comment from @joel.d, you should do:
NSURL *urlOption1 = [NSURL URLWithString:[@"telprompt://" stringByAppendingString:phone]];
NSURL *urlOption2 = [NSURL URLWithString:[@"tel://" stringByAppendingString:phone]];
NSURL *targetURL = nil;
if ([UIApplication.sharedApplication canOpenURL:urlOption1]) {
targetURL = urlOption1;
} else if ([UIApplication.sharedApplication canOpenURL:urlOption2]) {
targetURL = urlOption2;
}
if (targetURL) {
if (@available(iOS 10.0, *)) {
[UIApplication.sharedApplication openURL:targetURL options:@{} completionHandler:nil];
} else {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
[UIApplication.sharedApplication openURL:targetURL];
#pragma clang diagnostic pop
}
}
This will first try to use the "telprompt://" URL, and if that fails, it will use the "tel://" URL. If both fails, you're trying to place a phone call on an iPad or iPod Touch.
Swift Version :
let phone = mymobileNO.titleLabel.text
let phoneUrl = URL(string: "telprompt://\(phone)"
let phoneFallbackUrl = URL(string: "tel://\(phone)"
if(phoneUrl != nil && UIApplication.shared.canOpenUrl(phoneUrl!)) {
UIApplication.shared.open(phoneUrl!, options:[String:Any]()) { (success) in
if(!success) {
// Show an error message: Failed opening the url
}
}
} else if(phoneFallbackUrl != nil && UIApplication.shared.canOpenUrl(phoneFallbackUrl!)) {
UIApplication.shared.open(phoneFallbackUrl!, options:[String:Any]()) { (success) in
if(!success) {
// Show an error message: Failed opening the url
}
}
} else {
// Show an error message: Your device can not do phone calls.
}
I came across this trying to add labels o some vertical radio boxes. I had to do this:
<%: Html.RadioButton("RadioGroup1", "Yes") %><label style="display:inline-block;padding-top:2px;">Yes</label><br />
<%: Html.RadioButton("RadioGroup1", "No") %><label style="display:inline-block;padding-top:3px;">No</label><br />
<%: Html.RadioButton("RadioGroup1", "Maybe") %><label style="display:inline-block;padding-top:4px;">Maybe</label><br />
This gets them to display properly, where the label is centered on the radio button, though I had to increment the top padding with each line, as you can see. The code isn't pretty, but the result is.
1) You can create rounded corner button by defining xml drawable and you can increase or decrease radius to increase or decrease roundness of button corner. Set this xml drawable as background of button.
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="4dp"
android:insetTop="6dp"
android:insetRight="4dp"
android:insetBottom="6dp">
<ripple android:color="?attr/colorControlHighlight">
<item>
<shape android:shape="rectangle"
android:tint="#0091ea">
<corners android:radius="10dp" />
<solid android:color="#1a237e" />
<padding android:bottom="6dp" />
</shape>
</item>
</ripple>
</inset>
2) To change default shadow and shadow transition animation between button states, you need to define selector and apply it to button using android:stateListAnimator property. For complete button customization reference : http://www.zoftino.com/android-button
In my case, I needed to allow many inactives and only one combination of two keys active, like this:
UUL_USR_IDF UUL_UND_IDF UUL_ATUAL
137 18 0
137 19 0
137 20 1
137 21 0
This seems to work:
CREATE UNIQUE NONCLUSTERED INDEX UQ_USR_UND_UUL_USR_IDF_UUL_ATUAL
ON USER_UND(UUL_USR_IDF, UUL_ATUAL)
WHERE UUL_ATUAL = 1;
Here are my test cases:
SELECT * FROM USER_UND WHERE UUL_USR_IDF = 137
insert into USER_UND values (137, 22, 1) --I CAN NOT => Cannot insert duplicate key row in object 'dbo.USER_UND' with unique index 'UQ_USR_UND_UUL_USR_IDF_UUL_ATUAL'. The duplicate key value is (137, 1).
insert into USER_UND values (137, 23, 0) --I CAN
insert into USER_UND values (137, 24, 0) --I CAN
DELETE FROM USER_UND WHERE UUL_USR_ID = 137
insert into USER_UND values (137, 22, 1) --I CAN
insert into USER_UND values (137, 27, 1) --I CAN NOT => Cannot insert duplicate key row in object 'dbo.USER_UND' with unique index 'UQ_USR_UND_UUL_USR_IDF_UUL_ATUAL'. The duplicate key value is (137, 1).
insert into USER_UND values (137, 28, 0) --I CAN
insert into USER_UND values (137, 29, 0) --I CAN
Raw CGI is kind of a pain, Django is kind of heavyweight. There are a number of simpler, lighter frameworks about, e.g. CherryPy. It's worth looking around a bit.
Angular runs change detection and when it finds that some values which has been passed to the child component have been changed, Angular throws the following error:
ExpressionChangedAfterItHasBeenCheckedError
click for more
In order to correct this we can use the AfterContentChecked
life cycle hook and
import { ChangeDetectorRef, AfterContentChecked} from '@angular/core';
constructor(
private cdref: ChangeDetectorRef) { }
ngAfterContentChecked() {
this.cdref.detectChanges();
}
Are you passing myClass out of a function, or expecting it to exist outside that function? As some others said, it is all about scope when you aren't allocating on the heap. When you leave the function, it goes away (eventually). One of the classic mistakes made by beginners is the attempt to create a local object of some class in a function and return it without allocating it on the heap. I can remember debugging this kind of thing back in my earlier days doing c++.
Here is the example for having one or more checkboxes value. If you have two or more checkboxes and need values then this would really help.
function myFunction() {_x000D_

var inputfields = document.getElementsByName("myCheck");_x000D_
var ar_inputflds = inputfields.length;_x000D_
_x000D_
for (var i = 0; i < ar_inputflds; i++) {_x000D_
if (inputfields[i].type == 'checkbox' && inputfields[i].checked == true)_x000D_
selchbox.push(inputfields[i].value);_x000D_
}_x000D_
return selchbox;_x000D_
_x000D_
}_x000D_
_x000D_
document.getElementById('btntest').onclick = function() {_x000D_
var selchb = myFunction();_x000D_
console.log(selchb);_x000D_
}
_x000D_
Checkbox:_x000D_
<input type="checkbox" name="myCheck" value="UK">United Kingdom_x000D_
<input type="checkbox" name="myCheck" value="USA">United States_x000D_
<input type="checkbox" name="myCheck" value="IL">Illinois_x000D_
<input type="checkbox" name="myCheck" value="MA">Massachusetts_x000D_
<input type="checkbox" name="myCheck" value="UT">Utah_x000D_
_x000D_
<input type="button" value="Click" id="btntest" />

Create a function calling it as the command you want to invoke. In this case, I need to use the ruok command.
Then, call the function and assign its result into a variable. In this case, I am assigning the result to the variable health.
function ruok {
echo ruok | nc *ip* 2181
}
health=echo ruok *ip*
Another approach when you have many updates would be to use COALESCE:
UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET
[ABC] = COALESCE(@ABC, [ABC]),
[ABCD] = COALESCE(@ABCD, [ABCD])

Run with glOrtho
:
./main 1
Run with glFrustrum
:
./main
Tested on Ubuntu 18.10.
Schema
Ortho: camera is a plane, visible volume a rectangle:
Frustrum: camera is a point,visible volume a slice of a pyramid:
Parameters
We are always looking from +z to -z with +y upwards:
glOrtho(left, right, bottom, top, near, far)
left
: minimum x
we seeright
: maximum x
we seebottom
: minimum y
we seetop
: maximum y
we see-near
: minimum z
we see. Yes, this is -1
times near
. So a negative input means positive z
.-far
: maximum z
we see. Also negative.Schema:
How it works under the hood
In the end, OpenGL always "uses":
glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);
If we use neither glOrtho
nor glFrustrum
, that is what we get.
glOrtho
and glFrustrum
are just linear transformations (AKA matrix multiplication) such that:
glOrtho
: takes a given 3D rectangle into the default cubeglFrustrum
: takes a given pyramid section into the default cubeThis transformation is then applied to all vertexes. This is what I mean in 2D:
The final step after transformation is simple:
x
, y
and z
are in [-1, +1]
z
component and take only x
and y
, which now can be put into a 2D screenWith glOrtho
, z
is ignored, so you might as well always use 0
.
One reason you might want to use z != 0
is to make sprites hide the background with the depth buffer.
Deprecation
glOrtho
is deprecated as of OpenGL 4.5: the compatibility profile 12.1. "FIXED-FUNCTION VERTEX TRANSFORMATIONS" is in red.
So don't use it for production. In any case, understanding it is a good way to get some OpenGL insight.
Modern OpenGL 4 programs calculate the transformation matrix (which is small) on the CPU, and then give the matrix and all points to be transformed to OpenGL, which can do the thousands of matrix multiplications for different points really fast in parallel.
Manually written vertex shaders then do the multiplication explicitly, usually with the convenient vector data types of the OpenGL Shading Language.
Since you write the shader explicitly, this allows you to tweak the algorithm to your needs. Such flexibility is a major feature of more modern GPUs, which unlike the old ones that did a fixed algorithm with some input parameters, can now do arbitrary computations.

Output:
The matrix for glOrtho
is really simple, composed only of scaling and translation:
scalex, 0, 0, translatex,
0, scaley, 0, translatey,
0, 0, scalez, translatez,
0, 0, 0, 1
as mentioned in the OpenGL 2 docs.
The glFrustum
matrix is not too hard to calculate by hand either, but starts getting annoying. Note how frustum cannot be made up with only scaling and translations like glOrtho
, more info at: https://gamedev.stackexchange.com/a/118848/25171
The GLM OpenGL C++ math library is a popular choice for calculating such matrices. http://glm.g-truc.net/0.9.2/api/a00245.html documents both an ortho
and frustum
operations.
Better example is here
try {
myDB = this.openOrCreateDatabase("DatabaseName", MODE_PRIVATE, null);
/* Create a Table in the Database. */
myDB.execSQL("CREATE TABLE IF NOT EXISTS "
+ TableName
+ " (Field1 VARCHAR, Field2 INT(3));");
/* Insert data to a Table*/
myDB.execSQL("INSERT INTO "
+ TableName
+ " (Field1, Field2)"
+ " VALUES ('Saranga', 22);");
/*retrieve data from database */
Cursor c = myDB.rawQuery("SELECT * FROM " + TableName , null);
int Column1 = c.getColumnIndex("Field1");
int Column2 = c.getColumnIndex("Field2");
// Check if our result was valid.
c.moveToFirst();
if (c != null) {
// Loop through all Results
do {
String Name = c.getString(Column1);
int Age = c.getInt(Column2);
Data =Data +Name+"/"+Age+"\n";
}while(c.moveToNext());

Using a request scoped bean outside of an actual web request
You can potentially roll your own Stream
variant by wrapping your lambda to throw an unchecked exception and then later unwrapping that unchecked exception on terminal operations:
@FunctionalInterface
public interface ThrowingPredicate<T, X extends Throwable> {
public boolean test(T t) throws X;
}
@FunctionalInterface
public interface ThrowingFunction<T, R, X extends Throwable> {
public R apply(T t) throws X;
}
@FunctionalInterface
public interface ThrowingSupplier<R, X extends Throwable> {
public R get() throws X;
}
public interface ThrowingStream<T, X extends Throwable> {
public ThrowingStream<T, X> filter(
ThrowingPredicate<? super T, ? extends X> predicate);
public <R> ThrowingStream<T, R> map(
ThrowingFunction<? super T, ? extends R, ? extends X> mapper);
public <A, R> R collect(Collector<? super T, A, R> collector) throws X;
// etc
}
class StreamAdapter<T, X extends Throwable> implements ThrowingStream<T, X> {
private static class AdapterException extends RuntimeException {
public AdapterException(Throwable cause) {
super(cause);
}
}
private final Stream<T> delegate;
private final Class<X> x;
StreamAdapter(Stream<T> delegate, Class<X> x) {
this.delegate = delegate;
this.x = x;
}
private <R> R maskException(ThrowingSupplier<R, X> method) {
try {
return method.get();
} catch (Throwable t) {
if (x.isInstance(t)) {
throw new AdapterException(t);
} else {
throw t;
}
}
}
@Override
public ThrowingStream<T, X> filter(ThrowingPredicate<T, X> predicate) {
return new StreamAdapter<>(
delegate.filter(t -> maskException(() -> predicate.test(t))), x);
}
@Override
public <R> ThrowingStream<R, X> map(ThrowingFunction<T, R, X> mapper) {
return new StreamAdapter<>(
delegate.map(t -> maskException(() -> mapper.apply(t))), x);
}
private <R> R unmaskException(Supplier<R> method) throws X {
try {
return method.get();
} catch (AdapterException e) {
throw x.cast(e.getCause());
}
}
@Override
public <A, R> R collect(Collector<T, A, R> collector) throws X {
return unmaskException(() -> delegate.collect(collector));
}
}
Then you could use this the same exact way as a Stream
:
Stream<Account> s = accounts.values().stream();
ThrowingStream<Account, IOException> ts = new StreamAdapter<>(s, IOException.class);
return ts.filter(Account::isActive).map(Account::getNumber).collect(toSet());
This solution would require quite a bit of boilerplate, so I suggest you take a look at the library I already made which does exactly what I have described here for the entire Stream
class (and more!).
I'm using OS Catalina and used the solution of Babul Prabhakar. But when I closed the terminal, pod still was unable.
So I put the exports:
$ export GEM_HOME=$HOME/Software/ruby
$ export PATH=$PATH:$HOME/Software/ruby/bin
inside this file(put this command below inside the terminal):
nano ~/.bash_profile
Then save the file, close the terminal and open it up again and type:
pod --version
Instead of creating a crontab to run as the root user, create a crontab for the user that you want to run the script. In your case, crontab -u www-data -e
will edit the crontab for the www-data user. Just put your full command in there and remove it from the root user's crontab.

# replace NAs with mean (or whatever function you like)

This will ignore the whitespace as well so, your never got the Blank textNodes..code using core Javascript.
var oDiv = document.getElementById("MyDiv");
var firstText = "";
for (var i = 0; i < oDiv.childNodes.length; i++) {
var curNode = oDiv.childNodes[i];
whitespace = /^\s*$/;
if (curNode.nodeName === "#text" && !(whitespace.test(curNode.nodeValue))) {
firstText = curNode.nodeValue;
break;
}
}

JsFiddle of how you could do it without using inline JS.
How not to do it:
When building an image, you could also tag it this way.
docker build -t ubuntu:14.04 .
Then you build it again with another tag:
docker build -t ubuntu:latest .
If your Dockerfile makes good use of the cache, the same image should come out, and it effectively does the same as retagging the same image. If you do docker images
then you will see that they have the same ID.
There's probably a case where this goes wrong though... But like @david-braun said, you can't create tags with Dockerfiles themselves, just with the docker command.
As of today the download URL for the latest version of the extension is embedded verbatim in the source of the page on Marketplace, e.g. source at URL:
https://marketplace.visualstudio.com/items?itemName=lukasz-wronski.ftp-sync
contains string:
https://lukasz-wronski.gallerycdn.vsassets.io/extensions/lukasz-wronski/ftp-sync/0.3.3/1492669004156/Microsoft.VisualStudio.Services.VSIXPackage
I use following Python regexp to extract dl URL:
urlre = re.search(r'source.+(http.+Microsoft\.VisualStudio\.Services\.VSIXPackage)', content)
if urlre:
return urlre.group(1)
element.defaultValue
will give you the original value.
Please note that this only works on the initial value.
If you are needing this to persist the "old" value every time it changes, an expando property or similar method will meet your needs
there are several ways. You can use this method:
start = @selected_date.beginning_of_day
end = @selected_date.end_of_day
@comments = Comment.where("DATE(created_at) BETWEEN ? AND ?", start, end)
Or this:
@comments = Comment.where(:created_at => @selected_date.beginning_of_day..@selected_date.end_of_day)
you should give permission on your db

What is an Intent?
An Intent is a specific command in Android that allows you to send a command to the Android OS to do something specific. Think of it as an action that needs to take place. There are many actions that can be done such as sending an email, or attaching a photo to an email, or even launching an application. The logical workflow of creating an intent is usually as follows: a. Create the Intent b. Add Intent options -> Ex. what type of intent we are sending to the OS or any attributes associated with that intent, such as a text string or something being passed along with the intent c. RUN the Intent
Real-Life Example: Let's say I wake up in the morning and I "INTEND" to go to the washroom. I will first have to THINK about going to the washroom, but that DOESN'T really gets me to the washroom. I will then have to tell my brain to get out of bed first, then walk to the washroom, and then release, then go and wash my hands, then go and wipe my hands. Once I know where I'm going I SEND the command to begin and my body takes action.
What is Pending Intents?
Continuing from the real-life example, let's say I want to take a shower but I want to shower AFTER I brush my teeth and eat breakfast. So I know I won't be showering until at least 30-40 minutes. I still have in my head that I need to prepare my clothes, and then walk up the stairs back to the bathroom, then undress and then shower. However, this will not happen until 30-40 minutes have passed. I now have a PENDING intent to shower. It is PENDING for 30-40 minutes.
That is pretty much the difference between a Pending Intent and a Regular Intent. Regular Intents can be created without a Pending Intent, however, in order to create a Pending Intent you need to have a Regular Intent setup first.

@for /f "skip=1" %%p in ('wmic cpu get loadpercentage /VALUE') do (
for /F "tokens=2 delims==" %%J in ("%%p") do echo %%J
)
If you're checking for explicit types, why are you declaring those variables as T
's?
T HowToCast<T>(T t)
{
if (typeof(T) == typeof(string))
{
var newT1 = "some text";
var newT2 = t; //this builds but I'm not sure what it does under the hood.
var newT3 = t.ToString(); //for sure the string you want.
}
return t;
}

"Another reason can be if you have a JAR file located somewhere in your project folder and then added it as a Java Path Library. It does not show up under the Package Explorer, so you don't notice it, but it does get counted twice, causing the dreaded Dalvik error." answered Jan 2 '12 at 6:23 Rashmi.B
Meaning:
If you have for instance these two libraries (.jar) in your lib folder:
and then these two folders are also added to your build path:
means that they are counted twice, thus giving you the error!
Solution:
Try the arithmetic-expression version of for
:
max=10
for (( i=2; i <= $max; ++i ))
do
echo "$i"
done
This is available in most versions of bash, and should be Bourne shell (sh) compatible also.
I had that issue and I solved by doing this:
.done(function() {
$(this).find("input").val("");
$("#feedback").trigger("reset");
});
I added this code after my script as I used jQuery. Try same)
<script type="text/JavaScript">
$(document).ready(function() {
$("#feedback").submit(function(event) {
event.preventDefault();
$.ajax({
url: "feedback_lib.php",
type: "post",
data: $("#feedback").serialize()
}).done(function() {
$(this).find("input").val("");
$("#feedback").trigger("reset");
});
});
});
</script>

I have solved this issue,
login to server computer where SQL Server is installed get you csv file on server computer and execute your query it will insert the records.
If you will give datatype compatibility issue change the datatype for that column
If the problem still persists even after putting the after build in the correct project try using "copy" instead of xcopy. This worked for me.

The two calls have different meanings that have nothing to do with performance; the fact that it speeds up the execution time is (or might be) just a side effect. You should understand what each of them does and not blindly include them in every program because they look like an optimization.
ios_base::sync_with_stdio(false);
This disables the synchronization between the C and C++ standard streams. By default, all standard streams are synchronized, which in practice allows you to mix C- and C++-style I/O and get sensible and expected results. If you disable the synchronization, then C++ streams are allowed to have their own independent buffers, which makes mixing C- and C++-style I/O an adventure.
Also keep in mind that synchronized C++ streams are thread-safe (output from different threads may interleave, but you get no data races).
cin.tie(NULL);
This unties cin
from cout
. Tied streams ensure that one stream is flushed automatically before each I/O operation on the other stream.
By default cin
is tied to cout
to ensure a sensible user interaction. For example:
std::cout << "Enter name:";
std::cin >> name;
If cin
and cout
are tied, you can expect the output to be flushed (i.e., visible on the console) before the program prompts input from the user. If you untie the streams, the program might block waiting for the user to enter their name but the "Enter name" message is not yet visible (because cout
is buffered by default, output is flushed/displayed on the console only on demand or when the buffer is full).
So if you untie cin
from cout
, you must make sure to flush cout
manually every time you want to display something before expecting input on cin
.
In conclusion, know what each of them does, understand the consequences, and then decide if you really want or need the possible side effect of speed improvement.
Put my two cents in :
function convertSecondsToMinutesAndSeconds(seconds){
var minutes;
var seconds;
minutes = Math.floor(seconds/60);
seconds = seconds%60;
return [minutes, seconds];
}
So this :
var minutesAndSeconds = convertSecondsToMinutesAndSeconds(101);
Will have the following output :
[1,41];
Then you can print it like so :
console.log('TIME : ' + minutesSeconds[0] + ' minutes, ' + minutesSeconds[1] + ' seconds');
//TIME : 1 minutes, 41 seconds
/^$|\s+/
if this matched, there's whitespace or its empty.
I resolved my problem doing this:
json_encode($array, JSON_UNESCAPED_UNICODE)
to encode the data;The result is a .json file encoded to ANSI as UTF-8.
You can use one of the functions of jFunc - use the function "jFunc_CanvasFilterGrayscale" http://jfunc.com/jFunc-functions.aspx
Here is a new one (Note: in Tech Preview stage): http://www.dot42.com
It is basically a Visual Studio add-in that lets you compile your C# code directly to DEX code. This means there is no run-time requirement such as Mono.

UPDATE: all sources are now on https://github.com/dot42
Yes. Empty or incomplete headers or response body typically caused by broken connections or server side crash can cause 502 errors if accessed via a gateway or proxy.

Open the file bootstrap-datepicker.js
Go to line 1399 and find format: 'mm/dd/yyyy'

Now you can change the date format here.
How are you setting blob to DB? You should do:
//imagine u have a a prepared statement like:
PreparedStatement ps = conn.prepareStatement("INSERT INTO table VALUES (?)");
String blobString= "This is the string u want to convert to Blob";
oracle.sql.BLOB myBlob = oracle.sql.BLOB.createTemporary(conn, false,oracle.sql.BLOB.DURATION_SESSION);
byte[] buff = blobString.getBytes();
myBlob.putBytes(1,buff);
ps.setBlob(1, myBlob);
ps.executeUpdate();
Here is a solution that does not require a separate module. However, it is very crude, and does not implement much error handling. It could also use more tests, but it will get you going. If you are parsing very large files, you may want to seek an alternative. Also, see this solution from Ben Nadel.

If you want only the hour of your datetime, then you can use DATEPART()
- SQL Server:
declare @dt datetime
set @dt = '2012-09-10 08:25:53'
select datepart(hour, @dt) -- returns 8
In SQL Server 2008+ you can CAST()
as time:
declare @dt datetime
set @dt = '2012-09-10 08:25:53'
select CAST(@dt as time) -- returns 08:25:53
Surely using array_map
and if using a container implementing ArrayAccess
to derive objects is just a smarter, semantic way to go about this?
Array map semantics are similar across most languages and implementations that I've seen. It's designed to return a modified array based upon input array element (high level ignoring language compile/runtime type preference); a loop is meant to perform more logic.
For retrieving objects by ID / PK, depending upon if you are using SQL or not (it seems suggested), I'd use a filter to ensure I get an array of valid PK's, then implode with comma and place into an SQL IN()
clause to return the result-set. It makes one call instead of several via SQL, optimising a bit of the call->wait
cycle. Most importantly my code would read well to someone from any language with a degree of competence and we don't run into mutability problems.
<?php
$arr = [0,1,2,3,4];
$arr2 = array_map(function($value) { return is_int($value) ? $value*2 : $value; }, $arr);
var_dump($arr);
var_dump($arr2);
vs
<?php
$arr = [0,1,2,3,4];
foreach($arr as $i => $item) {
$arr[$i] = is_int($item) ? $item * 2 : $item;
}
var_dump($arr);
If you know what you are doing will never have mutability problems (bearing in mind if you intend upon overwriting $arr
you could always $arr = array_map
and be explicit.
$("#elementID").html("another string");
Simple solution
setcookie("NAME", "VALUE", time()+3600, '/', EXAMPLE.COM);
Setcookie's 5th parameter determines the (sub)domains that the cookie is available to. Setting it to (EXAMPLE.COM) makes it available to any subdomain (eg: SUBDOMAIN.EXAMPLE.COM )
I've done this on a regular (local) TextView
, and it should work on the remote variety since the docs list the method as equivalent between the two:
remote_text_view.setText(Html.fromHtml("This is <del>crossed off</del>."));
I'm monitoring the download progress by using
while true;
do
du -sh ~/.cocoapods/;
sleep 3;
done
the progress is very slow... and failed few times.
But somehow after increasing the git buffer limit by using this command line git config --global http.postBuffer 2M
The download speed is improving greatly and after downloading in total 347 Mb on ./cocoapods
folder, the progress seems to stop and network activity is also stopping.
but after waiting few minutes, turn out that cocoapod is verifying and extracting the repo and makes the total size up to 853 Mb.
notes: I'm doing it on 23 Oct 2016.
Assuming you have other data types (and not only string) in your list try this. This removes trailing and leading zeros from strings and leaves other data types untouched. This also handles the special case s = '0'
e.g
a = ['001', '200', 'akdl00', 200, 100, '0']
b = [(lambda x: x.strip('0') if isinstance(x,str) and len(x) != 1 else x)(x) for x in a]
b
>>>['1', '2', 'akdl', 200, 100, '0']
Use a combination of Microsoft specific CSS rules to filter IE11:
<!doctype html>
<html>
<head>
<title>IE10/11 Media Query Test</title>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<style>
@media all and (-ms-high-contrast:none)
{
.foo { color: green } /* IE10 */
*::-ms-backdrop, .foo { color: red } /* IE11 */
}
</style>
</head>
<body>
<div class="foo">Hi There!!!</div>
</body>
</html>
Filters such as this work because of the following:
When a user agent cannot parse the selector (i.e., it is not valid CSS 2.1), it must ignore the selector and the following declaration block (if any) as well.
<!doctype html>_x000D_
<html>_x000D_
<head>_x000D_
<title>IE10/11 Media Query Test</title>_x000D_

If you want to order by count (sound simple but i can`t found an answer on stack of how to do that) you can do:
SELECT town, count(town) as total FROM user
GROUP BY town ORDER BY total DESC
Well, you can use xpath utility. I guess perl's XML::Xpath contains it.
I've been using:
@media only screen and (min-width: 768px) {
/* tablets and desktop */
}
@media only screen and (max-width: 767px) {
/* phones */
}
@media only screen and (max-width: 767px) and (orientation: portrait) {
/* portrait phones */
}
It keeps things relatively simple and allows you to do something a bit different for phones in portrait mode (a lot of the time I find myself having to change various elements for them).
The color for your buttons comes from the btn-x classes (e.g., btn-primary, btn-success), so if you want to manually change the colors by writing your own custom css rules, you'll need to change:
/*This is modifying the btn-primary colors but you could create your own .btn-something class as well*/
.btn-primary {
color: #fff;
background-color: #0495c9;
border-color: #357ebd; /*set the color you want here*/
}
.btn-primary:hover, .btn-primary:focus, .btn-primary:active, .btn-primary.active, .open>.dropdown-toggle.btn-primary {
color: #fff;
background-color: #00b3db;
border-color: #285e8e; /*set the color you want here*/
}

you can do these line on your mysql query browser or something

This is a comment on the top answer, but I felt it was worth its own answer because it helped me answer the problem.
If you want to keep Bootstrap declared after JQuery UI (I did because I wanted to use the Bootstrap tooltip), declaring the following (I declared it after $(document).ready
) will allow the button to appear again (answer from https://stackoverflow.com/a/23428433/4660870)
var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
$.fn.bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality
You need to double escape any RegExp characters (once for the slash in the string and once for the regexp):
"$TESTONE $TESTONE".replace( new RegExp("\\$TESTONE","gm"),"foo")
Otherwise, it looks for the end of the line and 'TESTONE' (which it never finds).
Personally, I'm not a big fan of building regexp's using strings for this reason. The level of escaping that's needed could lead you to drink. I'm sure others feel differently though and like drinking when writing regexes.

#box.hide {_x000D_

I decided to make this toggleable so you can see how it does not affect the flow of the surrounding text (run it and press the button to show/hide the floated absolute box).
foreach over a statement is just a syntax sugar for the regular one-way fetch() loop. If you want to loop over your data more than once, select it as a regular array first
$sql = "SELECT * FROM users";
$stm = $dbh->query($sql);
// here you go:
$users = $stm->fetchAll();
foreach ($users as $row) {
print $row["name"] . "-" . $row["sex"] ."<br/>";
}
echo "<br/>";
foreach ($users as $row) {
print $row["name"] . "-" . $row["sex"] ."<br/>";
}
Also quit that try..catch
thing. Don't use it, but set the proper error reporting for PHP and PDO

:
finalName:
Name of the generated JAR.
Type: java.lang.String

You should also be able to use this option on the command line with:
mvn -Djar.finalName=myCustomName ...
You should get myCustomName.jar, although I haven't tested this.
Basically you will need to read the file line by line.
Then you will need to split each line by the delimiter, say a comma (CSV stands for comma-separated values), with
String[] strArr=line.split(",");
This will turn it into an array of strings which you can then manipulate, for example with
String name=strArr[0];
int yearOfBirth = Integer.valueOf(strArr[1]);
int monthOfBirth = Integer.valueOf(strArr[2]);
int dayOfBirth = Integer.valueOf(strArr[3]);
GregorianCalendar dob=new GregorianCalendar(yearOfBirth, monthOfBirth, dayOfBirth);
Student student=new Student(name, dob); //lets pretend you are creating instances of Student
You will need to do this for every line so wrap this code into a while loop. (If you don't know the delimiter just open the file in a text editor.)
SQL Server Reporting Services (SSRS)
SSRS can remain active even if you uninstall SQL Server.
To stop the service:
Open SQL Server Configuration Manager. Select “SQL Server Services” in the left-hand pane. Double-click “SQL Server Reporting Services”. Hit Stop. Switch to the Service tab and set the Start Mode to “Manual”.
Skype
Irritatingly, Skype can switch to port 80. To disable it, select Tools > Options > Advanced > Connection
then uncheck “Use port 80 and 443 as alternatives for incoming connections”
.
IIS (Microsoft Internet Information Server)
For Windows 7 (or vista) its the most likely culprit. You can stop the service from the command line.
Open command line cmd.exe
and type:
net stop was /y
For older versions of Windows type:
net stop iisadmin /y
Other
If this does not solve the problem further detective work is necessary if IIS, SSRS and Skype are not to blame. Enter the following on the command line:
netstat -ao
The active TCP addresses and ports will be listed. Locate the line with local address “0.0.0.0:80" and note the PID value. Start Task Manager. Navigate to the Processes tab and, if necessary, click View > Select Columns to ensure “PID (Process Identifier)” is checked. You can now locate the PID you noted above. The description and properties should help you determine which application is using the port.

Using the Cors option in the API gateway, I used the following settings shown above
Also, note, that your function must return a HTTP status 200 in response to an OPTIONS request, or else CORS will also fail.
use setAttribute() and removeAttribute()
function disbtn(e) {

}
Following will display 25 records excluding first 50 records works in SQL Server 2012.
SELECT * FROM MyTable ORDER BY ID OFFSET 50 ROWS FETCH NEXT 25 ROWS ONLY;
you can replace ID as your requirement
With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.
In my case it was
username : root
password : mysql
Using : Wamp server 3.1.0
Adding the System.Configuration
as reference to all the projects will solve this.
Go to Project
-> Add Reference
In the box that appears, click the All assemblies
list tab in the left hand list.
In the central list, scroll to System.Configuration
and make sure the box is checked.
Click ok to apply, and you'll now be able to access the ConfigurationManager
class.
Save the commands in a .SQL
file, ex: ClearTables.sql
, say in your C:\temp
folder.
Contents of C:\Temp\ClearTables.sql
Delete from TableA;
Delete from TableB;
Delete from TableC;
Delete from TableD;
Delete from TableE;
Then use sqlcmd
to execute it as follows. Since you said the database is remote, use the following syntax (after updating for your server and database instance name).
sqlcmd -S <ComputerName>\<InstanceName> -i C:\Temp\ClearTables.sql
For example, if your remote computer name is SQLSVRBOSTON1 and Database instance name is MyDB1, then the command would be.
sqlcmd -E -S SQLSVRBOSTON1\MyDB1 -i C:\Temp\ClearTables.sql
Also note that -E
specifies default authentication. If you have a user name and password to connect, use -U
and -P
switches.
You will execute all this by opening a CMD
command window.
Using a Batch File.
If you want to save it in a batch file and double-click to run it, do it as follows.
Create, and save the ClearTables.bat
like so.
echo off
sqlcmd -E -S SQLSVRBOSTON1\MyDB1 -i C:\Temp\ClearTables.sql
set /p delExit=Press the ENTER key to exit...:
Then double-click it to run it. It will execute the commands and wait until you press a key to exit, so you can see the command output.
Check if you imported the header files of classes that are throwing this error.
You can also use:
Collections.sort(list, new Comparator<CustomObject>() {
public int compare(CustomObject obj1, CustomObject obj2) {
return obj1.id - obj2.id;
}
});
System.out.println(list);
I believe this is exactly what you're looking for:

For compressing the file you can use below code
var fs = require("fs");
var zlib = require('zlib');
fs.createReadStream('input.txt').pipe(zlib.createGzip())
.pipe(fs.createWriteStream('input.txt.gz'));
console.log("File Compressed.");
For decompressing the same file you can use below code
var fs = require("fs");
var zlib = require('zlib');
fs.createReadStream('input.txt.gz')
.pipe(zlib.createGunzip())
.pipe(fs.createWriteStream('input.txt'));
console.log("File Decompressed.");
You don't need any date-specific functions for this, it's just string manipulation:
var parts = fecha2.value.split('-');
var newdate = parts[1]+'-'+parts[2]+'-'+(parseInt(parts[0], 10)%100);
You can use int
and set the base to 2
(for binary):
>>> binary = raw_input('enter a number: ')
enter a number: 11001
>>> int(binary, 2)
25
>>>
However, if you cannot use int
like that, then you could always do this:
binary = raw_input('enter a number: ')
decimal = 0
for digit in binary:
decimal = decimal*2 + int(digit)
print decimal
Below is a demonstration:
>>> binary = raw_input('enter a number: ')
enter a number: 11001
>>> decimal = 0
>>> for digit in binary:
... decimal = decimal*2 + int(digit)
...
>>> print decimal
25

searchfile = open("file.txt", "r")
for line in searchfile:
if "searchphrase" in line: print line
searchfile.close()
To print out multiple lines (in a simple way)
f = open("file.txt", "r")
searchlines = f.readlines()
f.close()
for i, line in enumerate(searchlines):
if "searchphrase" in line:
for l in searchlines[i:i+3]: print l,
print
The comma in print l,
prevents extra spaces from appearing in the output; the trailing print statement demarcates results from different lines.
Or better yet (stealing back from Mark Ransom):
with open("file.txt", "r") as f:
searchlines = f.readlines()
for i, line in enumerate(searchlines):
if "searchphrase" in line:
for l in searchlines[i:i+3]: print l,
print
when I create my JLabel and enter the text to it, there is no wordwrap or anything
HTML formatting can be used to cause word wrap in any Swing component that offers styled text. E.G. as demonstrated in this answer.
The easiest thing to do is to create a file.txt
file and pass the link url link so:
https://www.youtube.com/watch?v=5Lj1BF0Kn8c&list=PL9YFoJnn53xyf9GNZrtiraspAIKc80s1i
make sure to include the -a
parameter in terminal:
youtube-dl -a file.txt
You can convert anything to a String as long as you choose what to print. The requirement was quite simple since Objet.toString()
can return a default dumb string: package.classname + @ + object number
.
If your print method should return an XML or JSON serialization, the basic result of toString() wouldn't be acceptable. Even though the method succeed.
Here is a simple example to show that Java can be dumb
public class MockTest{
String field1;
String field2;
public MockTest(String field1,String field2){
this.field1=field1;
this.field2=field2;
}
}
System.out.println(new MockTest("a","b");
will print something package.Mocktest@3254487
! Even though you only have two String members and this could be implemented to print
Mocktest@3254487{"field1":"a","field2":"b"}
(or pretty much how it appears in the debbuger)
THE C WAY
You can use gets
function found in cstdio(stdio.h in c):
#include<cstdio>
int main(){
char name[256];
gets(name); // for input
puts(name);// for printing
}
THE C++ WAY
gets
is removed in c++11.
[Recommended]:You can use getline(cin,name) which is in string.h
or cin.getline(name,256) which is in iostream
itself.
#include<iostream>
#include<string>
using namespace std;
int main(){
char name1[256];
string name2;
cin.getline(name1,256); // for input
getline(cin,name2); // for input
cout<<name1<<"\n"<<name2;// for printing
}
In you keyup/down handler you just need to set the scrollTop
property of the div you want to scroll to make it scroll down (or up).
For example:
JSX:
<div ref="foo">{content}</div>
keyup/down handler:
this.refs.foo.getDOMNode().scrollTop += 10
If you do something similar to above, your div will scroll down 10 pixels (assuming the div is set to overflow auto
or scroll
in css, and your content is overflowing of course).
You will need to expand on this to find the offset of the element inside your scrolling div that you want to scroll the div down to, and then modify the scrollTop
to scroll far enough to show the element based on it's height.
Have a look at MDN's definitions of scrollTop, and offsetTop here:
https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollTop
https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/offsetTop
Each call to nextLine()
moves onto the next line, so when you are actually at the last readable line and the while
check passes inspection, the next call to nextLine()
will return EOF
.
Perhaps you could do one of the following instead:
If fileReader
is of type Scanner
:
while ((line = fileReader.hasNextLine()) != null) {
String line = fileReader.nextLine();
System.out.println(line);
}
If fileReader
is of type BufferedReader
:
String line;
while ((line = fileReader.readLine()) != null) {
System.out.println(line);
}
So you're reading the current line in the while condition and saving the line in a string for later use.
JavaScript is case-sensitive. The b
in getElementbyId
should be capitalized.
var content = document.getElementById("edit").innerHTML;
Take a look at this article which shows the registry keys you need to look for and provides a .NET library that will do this for you.
First, you should to determine if .NET 3.5 is installed by looking at HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.5\Install, which is a DWORD value. If that value is present and set to 1, then that version of the Framework is installed.
Look at HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.5\SP, which is a DWORD value which indicates the Service Pack level (where 0 is no service pack).
To be correct about things, you really need to ensure that .NET Fx 2.0 and .NET Fx 3.0 are installed first and then check to see if .NET 3.5 is installed. If all three are true, then you can check for the service pack level.

From a comment:
I want to sort each set.
That's easy. For any set s
(or anything else iterable), sorted(s)
returns a list of the elements of s
in sorted order:
>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']
Note that sorted
is giving you a list
, not a set
. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2}
and {2, 1}
are the same set.
You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).
The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key
function:
>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']
For more information, see the Sorting HOWTO in the official docs.
* See the comments for exceptions.
I find this method to be most friendly.
var b = BigInteger.valueOf(x).toByteArray();
var l = new BigInteger(b);
Swift version:
override func viewDidLoad() {
super.viewDidLoad()
// Assign your color to this property, for example here we assign the red color.
tableView.separatorColor = UIColor.redColor()
}
My preferred option on 2.0.0 and up is to create a 404 route and also allow a ** route path to resolve to the same component. This allows you to log and display more information about the invalid route rather than a plain redirect which can act to hide the error.
Simple 404 example:
{ path '/', component: HomeComponent },
// All your other routes should come first
{ path: '404', component: NotFoundComponent },
{ path: '**', component: NotFoundComponent }
To display the incorrect route information add in import to router within NotFoundComponent:
import { Router } from '@angular/router';
Add it to the constructior of NotFoundComponent:
constructor(public router: Router) { }
Then you're ready to reference it from your HTML template e.g.
The page <span style="font-style: italic">{{router.url}}</span> was not found.
I tried the below code,
function executeQuery() {
$.ajax({
url: 'url/path/here',
success: function(data) {
// do something with the return value here if you like
}
});
setTimeout(executeQuery, 5000); // you could choose not to continue on failure...
}
$(document).ready(function() {
// run the first time; all subsequent calls will take care of themselves
setTimeout(executeQuery, 5000);
});
This didn't work as expected for the specified interval,the page didn't load completely and the function was been called continuously.
Its better to call setTimeout(executeQuery, 5000);
outside executeQuery()
in a separate function as below,
function executeQuery() {
$.ajax({
url: 'url/path/here',
success: function(data) {
// do something with the return value here if you like
}
});
updateCall();
}
function updateCall(){
setTimeout(function(){executeQuery()}, 5000);
}
$(document).ready(function() {
executeQuery();
});
This worked exactly as intended.
using(var database=new DatabaseEntities()){}
Don't use using statement. Just write like that
DatabaseEntities database=new DatabaseEntities ();{}
It will work.
For documentation on the using
statement see here.
It's subtle.
If the business requirement is "I want to audit the changes to the data - who did what and when?", you can usually use audit tables (as per the trigger example Keethanjan posted). I'm not a huge fan of triggers, but it has the great benefit of being relatively painless to implement - your existing code doesn't need to know about the triggers and audit stuff.
If the business requirement is "show me what the state of the data was on a given date in the past", it means that the aspect of change over time has entered your solution. Whilst you can, just about, reconstruct the state of the database just by looking at audit tables, it's hard and error prone, and for any complicated database logic, it becomes unwieldy. For instance, if the business wants to know "find the addresses of the letters we should have sent to customers who had outstanding, unpaid invoices on the first day of the month", you likely have to trawl half a dozen audit tables.
Instead, you can bake the concept of change over time into your schema design (this is the second option Keethanjan suggests). This is a change to your application, definitely at the business logic and persistence level, so it's not trivial.
For example, if you have a table like this:
CUSTOMER
---------
CUSTOMER_ID PK
CUSTOMER_NAME
CUSTOMER_ADDRESS
and you wanted to keep track over time, you would amend it as follows:
CUSTOMER
------------
CUSTOMER_ID PK
CUSTOMER_VALID_FROM PK
CUSTOMER_VALID_UNTIL PK
CUSTOMER_STATUS
CUSTOMER_USER
CUSTOMER_NAME
CUSTOMER_ADDRESS
Every time you want to change a customer record, instead of updating the record, you set the VALID_UNTIL on the current record to NOW(), and insert a new record with a VALID_FROM (now) and a null VALID_UNTIL. You set the "CUSTOMER_USER" status to the login ID of the current user (if you need to keep that). If the customer needs to be deleted, you use the CUSTOMER_STATUS flag to indicate this - you may never delete records from this table.
That way, you can always find what the status of the customer table was for a given date - what was the address? Have they changed name? By joining to other tables with similar valid_from and valid_until dates, you can reconstruct the entire picture historically. To find the current status, you search for records with a null VALID_UNTIL date.
It's unwieldy (strictly speaking, you don't need the valid_from, but it makes the queries a little easier). It complicates your design and your database access. But it makes reconstructing the world a lot easier.
First, lets extend the string object. Thanks to Ricardo Peres for the prototype, I think using the variable 'string' works better than 'needle' in the context of making it more readable.
String.prototype.beginsWith = function (string) {
return(this.indexOf(string) === 0);
};
Then you use it like this. Caution! Makes the code extremely readable.
var pathname = window.location.pathname;
if (pathname.beginsWith('/sub/1')) {
// Do stuff here
}
Not sure what you have tried so far, but its pretty simple. Just do this: http://plnkr.co/edit/kmEWh7?p=preview
html, body {
height: 100%;
}
footer {
position: absolute;
bottom: 0;
}
In my case, detach
and attach
worked:
getSupportFragmentManager()
.beginTransaction()
.detach(contentFragment)
.attach(contentFragment)
.commit();
cat
can also be used following a |
to write to a file, i.e. pipe feeds cat a stream of data
In all these scenarios outerScopeVar
is modified or assigned a value asynchronously or happening in a later time(waiting or listening for some event to occur),for which the current execution will not wait.So all these cases current execution flow results in outerScopeVar = undefined
Let's discuss each examples(I marked the portion which is called asynchronously or delayed for some events to occur):
1.
Here we register an eventlistner which will be executed upon that particular event.Here loading of image.Then the current execution continuous with next lines img.src = 'lolcat.png';
and alert(outerScopeVar);
meanwhile the event may not occur. i.e, funtion img.onload
wait for the referred image to load, asynchrously. This will happen all the folowing example- the event may differ.
2.
Here the timeout event plays the role, which will invoke the handler after the specified time. Here it is 0
, but still it registers an asynchronous event it will be added to the last position of the Event Queue
for execution, which makes the guaranteed delay.
3.
4.
Node can be consider as a king of asynchronous coding.Here the marked function is registered as a callback handler which will be executed after reading the specified file.
5.
Obvious promise (something will be done in future) is asynchronous. see What are the differences between Deferred, Promise and Future in JavaScript?

You need to clone in ssh not in https.
For that you need to set your ssh keys. I have prepared this little script that automates this:
#!/usr/bin/env bash
email="$1"
hostname="$2"
hostalias="$hostname"
keypath="$HOME/.ssh/${hostname}_rsa"
ssh-keygen -t rsa -C $email -f $keypath
if [ $? -eq 0 ]; then
cat >> ~/.ssh/config <<EOF
Host $hostalias
Hostname $hostname *.$hostname
User git
IdentitiesOnly yes
IdentityFile $keypath
EOF
fi
and run it like
bash script.sh [email protected] github.com
Change your remote url
git remote set-url origin [email protected]:user/foo.git
Add content of ~/.ssh/github.com_rsa.pub
to your ssh keys on github.com
Check connection
ssh -T [email protected]
df.iloc[df['columnX'].argmax()]
argmax()
would provide the index corresponding to the max value for the columnX. iloc
can be used to get the row of the DataFrame df for this index.
Be aware that if you want to have values in the reverse order, you can easily do so:
> example = matrix(c(1,1,1,4,3,3,2,349,393,392,459,49,32,94), ncol = 2)
> example[order(example[,1], decreasing = TRUE),]
[,1] [,2]
[1,] 4 459
[2,] 3 49
[3,] 3 32
[4,] 2 94
[5,] 1 349
[6,] 1 393
[7,] 1 392
Some additional steps may be needed to set both the project and default workspace JRE correctly, as MayoMan mentioned. Here is the complete sequence in Eclipse Luna:
Easy.... not.
For starters:
<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>
Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.
This would be the optimal solution:
<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>
You could use the add
method and pass it a negative number. However, you could also write a simpler method that doesn't use the Calendar
class such as the following
public static void addDays(Date d, int days)
{
d.setTime( d.getTime() + (long)days*1000*60*60*24 );
}
This gets the timestamp value of the date (milliseconds since the epoch) and adds the proper number of milliseconds. You could pass a negative integer for the days parameter to do subtraction. This would be simpler than the "proper" calendar solution:
public static void addDays(Date d, int days)
{
Calendar c = Calendar.getInstance();
c.setTime(d);
c.add(Calendar.DATE, days);
d.setTime( c.getTime().getTime() );
}
Note that both of these solutions change the Date
object passed as a parameter rather than returning a completely new Date
. Either function could be easily changed to do it the other way if desired.
Just like Grimtron suggests - here is a quick example to define it:
@echo off
set newline=^& echo.
echo hello %newline%world
C:\>test.bat
hello
world
Try this:
let copy = (JSON.parse(JSON.stringify(objectToCopy)));
It is a good solution until you are using very large objects or your object has unserializable properties.
In order to preserve type safety you could use a copy function in the class you want to make copies from:
getCopy(): YourClassName{
return (JSON.parse(JSON.stringify(this)));
}
or in a static way:
static createCopy(objectToCopy: YourClassName): YourClassName{
return (JSON.parse(JSON.stringify(objectToCopy)));
}
Future version of node will allow you to fork a process and pass messages to it and Ryan has stated he wants to find some way to also share file handlers, so it won't be a straight forward Web Worker implementation.
At this time there is not an easy solution for this but it's still very early and node is one of the fastest moving open source projects I've ever seen so expect something awesome in the near future.
I did git revert a multiple times ,and it worked for me make sure un-check the files while reverting you need changes. Stash your changes and pull again.

The tutorial @Henrik mentioned is an excellent resource for learning how to create plots with the ggplot2
package.
An example with your data:
# transforming the data from wide to long
library(reshape2)
dfm <- melt(df, id = "TY")
# creating a scatterplot
ggplot(data = dfm, aes(x = TY, y = value, color = variable)) +
geom_point(size=5) +
labs(title = "Temperatures\n", x = "TY [°C]", y = "Txxx", color = "Legend Title\n") +
scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
theme_bw() +
theme(axis.text.x = element_text(size = 14), axis.title.x = element_text(size = 16),
axis.text.y = element_text(size = 14), axis.title.y = element_text(size = 16),
plot.title = element_text(size = 20, face = "bold", color = "darkgreen"))
this results in:
As mentioned by @user2739472 in the comments: If you only want to change the legend text labels and not the colours from ggplot's default palette, you can use scale_color_hue(labels = c("T999", "T888"))
instead of scale_color_manual()
.
Simplest Definition of Looper & Handler:
Looper is a class that turns a thread into a Pipeline Thread and Handler gives you a mechanism to push tasks into it from any other threads.
Details in general wording:
So a PipeLine Thread is a thread which can accept more tasks from other threads through a Handler.
The Looper is named so because it implements the loop – takes the next task, executes it, then takes the next one and so on. The Handler is called a handler because it is used to handle or accept that next task each time from any other thread and pass to Looper (Thread or PipeLine Thread).
Example:
A Looper and Handler or PipeLine Thread's very perfect example is to download more than one images or upload them to a server (Http) one by one in a single thread instead of starting a new Thread for each network call in the background.
Read more here about Looper and Handler and the definition of Pipeline Thread:
If your test and webapp are in the same Maven project, you can use a property in the project POM. Then you can filter certain files which will allow Maven to set the property in those files. There are different ways to filter, but the most common is during the resources phase - http://books.sonatype.com/mvnref-book/reference/resource-filtering-sect-description.html
If the test and webapp are in different Maven projects, you can put the property in settings.xml, which is in your maven repository folder (C:\Documents and Settings\username.m2) on Windows. You will still need to use filtering or some other method to read the property into your test and webapp.
If you're using joda time and want the current time in milliseconds without your local offset you can use this:
long instant = DateTimeZone.UTC.getMillisKeepLocal(DateTimeZone.getDefault(), System.currentTimeMillis());
I prefer to use java.util.Scanner
:
try {
Scanner scanner = new Scanner(context.openFileInput(filename)).useDelimiter("\\Z");
StringBuilder sb = new StringBuilder();
while (scanner.hasNext()) {
sb.append(scanner.next());
}
scanner.close();
String result = sb.toString();
} catch (IOException e) {}
I do this with findup-sync
:
var findup = require('findup-sync');
var packagejson = require(findup('package.json'));
console.log(packagejson.version); // => '0.0.1'
You need to use a criteria, for example:
<?php
namespace Bundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Doctrine\Common\Collections\Criteria;
/**
* Thing controller
*/
class ThingController extends Controller
{
public function thingsAction(Request $request, $id)
{
$ids=explode(',',$id);
$criteria = new Criteria(null, <<DQL ordering expression>>, null, null );
$rep = $this->getDoctrine()->getManager()->getRepository('Bundle:Thing');
$things = $rep->matching($criteria);
return $this->render('Bundle:Thing:things.html.twig', [
'entities' => $things,
]);
}
}
Why not just use the option Find and Replace. (every code editor has it)?
For example Visual Studio Code (under Edit option):
You just type in old name and new name and replace everyhting in the project with one click.
NOTE: This renames only file content, NOT file and folder names. Do not forget renaming folders, eg. templates/my_app_name/
rename it to templates/my_app_new_name/
To dynamically change the color of a text box goto properties, goto font/Color and set the following expression
=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)
Same way for tolerance
=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")
You could use dataframe method notnull or inverse of isnull, or numpy.isnan:
In [332]: df[df.EPS.notnull()]
Out[332]:
STK_ID RPT_Date STK_ID.1 EPS cash
2 600016 20111231 600016 4.3 NaN
4 601939 20111231 601939 2.5 NaN
In [334]: df[~df.EPS.isnull()]
Out[334]:
STK_ID RPT_Date STK_ID.1 EPS cash
2 600016 20111231 600016 4.3 NaN

2 600016 20111231 600016 4.3 NaN
4 601939 20111231 601939 2.5 NaN
I prefer coloring by theme
<style name="CustomTheme" parent="android:Theme.Light">
<item name="android:windowBackground">@color/custom_theme_color</item>
<item name="android:colorBackground">@color/custom_theme_color</item>
</style>
The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date')
declare the date property like so: private _date: string;
. Also, make sure you are instantiating the model with the new
keyword. Lastly, access the property using regular dot notation.
Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :
let passcode = "secret passcode";
class Employee {
private _fullName: string;
get fullName(): string {
return this._fullName;
}
set fullName(newName: string) {
if (passcode && passcode == "secret passcode") {
this._fullName = newName;
}
else {
console.log("Error: Unauthorized update of employee!");
}
}
}
let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
console.log(employee.fullName);
}

For the sake of discussion...
You only need to look at the last digit in any given number to see if it is even or odd. Signed, unsigned, positive, negative - they are all the same with regards to this. So this should work all round: -
void tellMeIfItIsAnOddNumberPlease(int iToTest){
int iLastDigit;
iLastDigit = iToTest - (iToTest / 10 * 10);
if (iLastDigit % 2 == 0){
printf("The number %d is even!\n", iToTest);
} else {
printf("The number %d is odd!\n", iToTest);
}
}
The key here is in the third line of code, the division operator performs an integer division, so that result are missing the fraction part of the result. So for example 222 / 10 will give 22 as a result. Then multiply it again with 10 and you have 220. Subtract that from the original 222 and you end up with 2, which by magic is the same number as the last digit in the original number. ;-) The parenthesis are there to remind us of the order the calculation is done in. First do the division and the multiplication, then subtract the result from the original number. We could leave them out, since the priority is higher for division and multiplication than of subtraction, but this gives us "more readable" code.
We could make it all completely unreadable if we wanted to. It would make no difference whatsoever for a modern compiler: -
printf("%d%s\n",iToTest,0==(iToTest-iToTest/10*10)%2?" is even":" is odd");
But it would make the code way harder to maintain in the future. Just imagine that you would like to change the text for odd numbers to "is not even". Then someone else later on want to find out what changes you made and perform a svn diff or similar...
If you are not worried about portability but more about speed, you could have a look at the least significant bit. If that bit is set to 1 it is an odd number, if it is 0 it's an even number. On a little endian system, like Intel's x86 architecture it would be something like this: -
if (iToTest & 1) {
// Even
} else {
// Odd
}
Running 'py' command will tell you what version you have running. If you currently running 3.x and you need to switch to 2.x, you will need to use switch '-2'
py -2
If you need to switch from python 2.x to python 3.x you will have to use '-3' switch
py -3
If you would like to have Python 3.x as a default version, then you will need to create environment variable 'PY_PYTHON' and set it's value to 3.
It could be something like that:
var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];
var arrays = [], size = 3;
while (a.length > 0)
arrays.push(a.splice(0, size));
console.log(arrays);

You can use any of the below code to get the controller name
@HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString();
If you are using MVC 3 you can use
@ViewContext.Controller.ValueProvider.GetValue("controller").RawValue
The simplest code to align the iframe element:

I highly recommend the book "Pro Git" by Scott Chacon. Take time and really read it, while exploring an actual git repo as you do.
HEAD: the current commit your repo is on. Most of the time HEAD
points to the latest commit in your current branch, but that doesn't have to be the case. HEAD
really just means "what is my repo currently pointing at".
In the event that the commit HEAD
refers to is not the tip of any branch, this is called a "detached head".
master: the name of the default branch that git creates for you when first creating a repo. In most cases, "master" means "the main branch". Most shops have everyone pushing to master, and master is considered the definitive view of the repo. But it's also common for release branches to be made off of master for releasing. Your local repo has its own master branch, that almost always follows the master of a remote repo.
origin: the default name that git gives to your main remote repo. Your box has its own repo, and you most likely push out to some remote repo that you and all your coworkers push to. That remote repo is almost always called origin, but it doesn't have to be.
HEAD
is an official notion in git. HEAD
always has a well-defined meaning. master
and origin
are common names usually used in git, but they don't have to be.
=$W$4<=TODAY()
Returns true for dates up to and including today, false otherwise.
You could roll your own:
function resolve(objectToGetValueFrom, stringOfDotSeparatedParameters) {
var returnObject = objectToGetValueFrom,
parameters = stringOfDotSeparatedParameters.split('.'),
i,
parameter;
for (i = 0; i < parameters.length; i++) {
parameter = parameters[i];
returnObject = returnObject[parameter];
if (returnObject === undefined) {
break;
}
}
return returnObject;
};
And use it like this:
var result = resolve(obj, 'a.b.c.d');
* result is undefined if any one of a, b, c or d is undefined.

If you want to select only certain values from a single table you can try this
select distinct(*) from table_name where table_field in (1,1,2,3,4,5)
eg:
select first_name,phone_number from telephone_list where district id in (1,2,5,7,8,9)
if you want to select from multiple tables then you must go for UNION
.
If you just want to select the values 1, 1, 1, 2, 5, 1, 6 then you must do this
select 1
union select 1
union select 1
union select 2
union select 5
union select 1
union select 6

With selectable date ranges you might want to use something like this. My solution prevents selecting #from_date bigger than #to_date and changes #to_date startDate every time when user selects new date in #from_date box:
JS file:
var startDate = new Date('01/01/2012');
var FromEndDate = new Date();
var ToEndDate = new Date();
ToEndDate.setDate(ToEndDate.getDate()+365);
$('.from_date').datepicker({
weekStart: 1,
startDate: '01/01/2012',
endDate: FromEndDate,
autoclose: true
})
.on('changeDate', function(selected){
startDate = new Date(selected.date.valueOf());
startDate.setDate(startDate.getDate(new Date(selected.date.valueOf())));
$('.to_date').datepicker('setStartDate', startDate);
});
$('.to_date')
.datepicker({
weekStart: 1,
startDate: startDate,
endDate: ToEndDate,

when you want to access images which are in public/images folder and if you want to access it without using laravel functions, use as follows:
<img src={{url('/images/photo.type')}} width="" height="" alt=""/>
This works fine.
Code posted by you is correct and should have worked. But check exactly what you have in the char*
. If the correct value is to big to be represented, functions will return a positive or negative HUGE_VAL
. Check what you have in the char*
against maximum values that float
and double
can represent on your computer.
Check this page for strtod
reference and this page for atof
reference.
I have tried the example you provided in both Windows and Linux and it worked fine.
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("/spring-servlet.xml");
Then you can retrieve the bean:
MyClass myClass = (MyClass) context.getBean("myClass");
Reference: springbyexample.org
You can use the row_number()
function for this.
INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
row_number() over (order by (select NULL))
FROM PM_Ingrediants
WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
)
If you want to start with the maximum already in the table then do:
INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
FROM PM_Ingrediants cross join
(select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
)
Finally, you can just make the sequence
column an auto-incrementing identity column. This saves the need to increment it each time:
create table PM_Ingrediants_Arrangement_Temp ( . . .
sequence int identity(1, 1) -- and might consider making this a primary key too
. . .
)
Yes.
try {

catch (Exception $e) {
// handle or ignore exception here.

however note that php also has error codes separate from exceptions, a legacy holdover from before php had oop primitives. Most library builtins still raise error codes, not exceptions. To ignore an error code call the function prefixed with @:
@myfunction();

I switched to a different USB port and it suddenly got recognized...
Chrome is a Chromium-based browser and Chromium-based browsers only allow maximum 6 open socket connections at a time, when the 7th connection starts up it will just sit idle and wait for one of the 6 which are running to stop and then it will start running. Hence the error code ‘waiting for available sockets’, the 7th one will wait for one of those 6 sockets to become available and then it will start running.
You can either

Angular now has a type of iterate Object for exactly this scenario, called a Set. It fit my needs when I found this question searching. You create the set, "add" to it like you'd "push" to an array, and drop it in an ngFor just like an array. No pipes or anything.
this.myObjList = new Set();
...
this.myObjList.add(obj);
...
<ul>
<li *ngFor="let object of myObjList">
{{object}}
</li>
</ul>
You can get first and last day of previous month (with timestamp) in SQL Server by executing
--select dateadd(dd,-datepart(dd,getdate())+1,dateadd(mm,-1,getdate())) --first day of previous month
--select dateadd(dd,-datepart(dd,getdate()),getdate()) -- last day of previous month**
Assuming someTestObj
is a class
and not a struct
, the object is passed by reference, which means that both obj
and someTestObj
refer to the same object. E.g. changing name
in one will change it in the other. However, unlike if you passed it using the ref
keyword, setting obj = somethingElse
will not change someTestObj
.
An easy way would be to iterate over the items in the array in a loop.
for (var i = 0; i < arrayLength; i++) {
// (string) Compare the given string with myArray[i]
// if it matches store/save i and exit the loop.
}
There would definitely be better ways but for small number of items this should be blazing fast. Btw this is javascript but same method should work in almost every programming language.

This is how it can be fixed easily through Storyboard (iOS 11 and Xcode 9.1):
Select Table View > Size Inspector > Content Insets: Never
Is the

Yes.
or is it supplied by the HTML?
No. HTML has nothing to do with that. Read below.
Is it possible for me to define the

Yes.
If you want to send the following data to the web server:
name = John
age = 12
using application/x-www-form-urlencoded
would be like this:
name=John&age=12
As you can see, the server knows that parameters are separated by an ampersand &
. If &
is required for a parameter value then it must be encoded.
So how does the server know where a parameter value starts and ends when it receives an HTTP request using multipart/form-data
?
Using the boundary, similar to &
.
For example:
--XXX
Content-Disposition: form-data; name="name"
John
--XXX
Content-Disposition: form-data; name="age"
12
--XXX--
In that case, the boundary value is XXX
. You specify it in the Content-Type
header so that the server knows how to split the data it receives.
So you need to:
Use a value that won't appear in the HTTP data sent to the server.
Be consistent and use the same value everywhere in the request message.
If you want to translate your resources, just download MAT (Multilingual App Toolkit) for Visual Studio. https://marketplace.visualstudio.com/items?itemName=MultilingualAppToolkit.MultilingualAppToolkit-18308 This is the way to go to translate your projects in Visual Studio. https://blogs.msdn.microsoft.com/matdev/
From the point of view of making thinks simple, readable, consistent and easy to understand (since performance doesn't matter here):
Using embedded vars in double quotes can lead to complex and confusing situations when you want to embed object properties, multidimentional arrays etc. That is, generally when reading embedded vars, you cannot be instantly 100% sure of the final behavior of what you are reading.
You frequently need add crutches such as {}
and \
, which IMO adds confusion and makes concatenation readability nearly equivalent, if not better.
As soon as you need to wrap a function call around the var, for example htmlspecialchars($var)
, you have to switch to concatenation.
AFAIK, you cannot embed constants.
In some specific cases, "double quotes with vars embedding" can be useful, but generally speaking, I would go for concatenation (using single or double quotes when convenient)
In answer to Shubham Patwa: This way, the page is "jumpy" soon as the class "navbar-fixed-top" applies. That's because the #mainnav is throwen in and out of the document's DOM flow. This can result in an ugly UX if the page has a "critical height", jumping between fixed and un-fixed #mainnav position.
I altered the code this way, which seems to work fine (not pixel-perfect, but fine):
$(document).ready(function() {
var navpos = $('#mainnav').offset();
var navheight = $('#mainnav').outerHeight();
$(window).bind('scroll', function() {
if ($(window).scrollTop() > navpos.top) {
$('#mainnav').addClass('navbar-fixed-top');
$('body').css('marginTop',navheight);
}
else {
$('#mainnav').removeClass('navbar-fixed-top');
$('body').css('marginTop','0');
}
});
1) for example HTML code:
<ul>
<li>
<a href="#">firstlink</a>
<span><a href="#">second link</a>
</li>
</ul>
and css rules:
1) ul li a {color:red;}
2) ul > li > a {color:blue;}
">" - symbol mean that that will be searching only child selector (parentTag > childTag)
so first css rule will apply to all links (first and second) and second rule will apply anly to first link
2) As for efficiency - I think second will be more fast - as in case with JavaScript selectors. This rule read from right to left, this mean that when rule will parse by browser, it get all links on page: - in first case it will find all parent elements for each link on page and filter all links where exist parent tags "ul" and "li" - in second case it will check only parent node of link if it is "li" tag then -> check if parent tag of "li" is "ul"
some thing like this. Hope I describe all properly for you
csvreader.next() Return the next row of the reader’s iterable object as a list, parsed according to the current dialect.
Files.move(file.toPath(), fileNew.toPath());
works, but only when you close (or autoclose) ALL used resources (InputStream
, FileOutputStream
etc.) I think the same situation with file.renameTo
or FileUtils.moveFile
.
All the answers are outdated. It is best to use picasso for such purposes. It has a lot of features including background image processing.
Did I mention it is super easy to use:
Picasso.with(context).load(new File(...)).into(imageView);
After having all the proposed solutions fail my tests one way or the other, (edit: some were updated to pass the tests after I wrote this) I found the mozilla implementation for Array.indexOf and Array.lastIndexOf
I used those to implement my version of String.prototype.regexIndexOf and String.prototype.regexLastIndexOf as follows:
String.prototype.regexIndexOf = function(elt /*, from*/)
{
var arr = this.split('');
var len = arr.length;
var from = Number(arguments[1]) || 0;
from = (from < 0) ? Math.ceil(from) : Math.floor(from);
if (from < 0)
from += len;
for (; from < len; from++) {
if (from in arr && elt.exec(arr[from]) )
return from;
}
return -1;
};
String.prototype.regexLastIndexOf = function(elt /*, from*/)
{
var arr = this.split('');
var len = arr.length;
var from = Number(arguments[1]);
if (isNaN(from)) {
from = len - 1;
} else {
from = (from < 0) ? Math.ceil(from) : Math.floor(from);
if (from < 0)
from += len;
else if (from >= len)
from = len - 1;
}
for (; from > -1; from--) {
if (from in arr && elt.exec(arr[from]) )
return from;
}
return -1;
};
They seem to pass the test functions I provided in the question.
Obviously they only work if the regular expression matches one character but that is enough for my purpose since I will be using it for things like ( [abc] , \s , \W , \D )
I will keep monitoring the question in case someone provides a better/faster/cleaner/more generic implementation that works on any regular expression.
Since Python 3.5, you can also use splat *

You are initializing datatables twice, why?

"fnRowCallback": function( nRow, aData, iDisplayIndex, iDisplayIndexFull ) {
// Bold the grade for all 'A' grade browsers
if ( aData[4] == "A" )
{
$('td:eq(4)', nRow).html( '<b>A</b>' );
}
}
} );
} );
I realize this question was asked a long time ago, but I came here looking for answers and wasn't satisfied with anything I could find. I finally found the answer here:

To get the results from the form, use the FormCollection and then pull each individual value out by it's model name thus:
yourRecord.FieldName = Request.Form["FieldNameInModel"];
As far as I could tell it makes absolutely no difference what argument name you give to the FormCollection - use Request.Form["NameFromModel"] to retrieve it.
No, I did not dig down to see how th4e magic works under the covers. I just know it works...
I hope this helps somebody avoid the hours I spent trying different approaches before I got it working.
Just for the sake of completeness, appending values to a vector in a for loop is not really the philosophy in R. R works better by operating on vectors as a whole, as @BrodieG pointed out. See if your code can't be rewritten as:
ouput <- sapply(values, function(v) return(2*v))
Output will be a vector of return values. You can also use lapply
if values is a list instead of a vector.
you just need to divide the Date Time stamp by 1000 like:
var a = 1437203995000;
a = (a)/1000;
Extends : This is used to get attributes of a parent class into base class and may contain already defined methods that can be overridden in the child class.
Implements : This is used to implement an interface (parent class with functions signatures only but not their definitions) by defining it in the child class.
There is one special condition: "What if I want a new Interface to be the child of an existing interface?". In the above condition, the child interface extends the parent interface.
With a simple JSON object, you don't need jQuery:
for (var i in json) {
for (var j in json[i]) {
console.log(json[i][j]);

The mysql_install_db
script also needs the datadir
parameter:
mysql_install_db --user=root --datadir=$db_datapath
On Maria DB you use the install script mysql_install_db
to install and initialize. In my case I use an environment variable for the data path. Not only does mysqld
need to know where the data is (specified via commandline), but so does the install script.
You could use my tool uhubctl to control USB power per port for compatible USB hubs.
To create an option that needs no value, set the action

The default keybinding to toggle the integrated terminal is "Ctrl+`" according to VS Code keyboard shortcuts documentation page. If you don't like that shortcut you can change it in your keybindings file by adding something similar to:
{ "key": "ctrl+l", "command": "workbench.action.terminal.toggleTerminal" }
There does not seem to be a default keybinding for simply focusing the bottom panel. So, if you do not want to toggle the bottom panel, you will need to add something similar to the following to your keybindings file:
{ "key": "ctrl+t", "command": "workbench.action.focusPanel" }
In similar situations, I've done well by putting something like the following into /etc/rc.local:
cd /path/to/my/script
./my_script.py &
cd -
echo `date +%Y-%b-%d_%H:%M:%S` > /tmp/ran_rc_local # check that rc.local ran

alert ("File name has special characters ~`!#$%^&*+=-[]\\\';,/{}|\":<>? \nThese are not allowed\n");
return false;
