I created a WSGI middleware that stores the raw body from the environ['wsgi.input']
stream. I saved the value in the WSGI environ so I could access it from request.environ['body_copy']
within my app.
This isn't necessary in Werkzeug or Flask, as request.get_data()
will get the raw data regardless of content type, but with better handling of HTTP and WSGI behavior.
This reads the entire body into memory, which will be an issue if for example a large file is posted. This won't read anything if the Content-Length
header is missing, so it won't handle streaming requests.
from io import BytesIO
class WSGICopyBody(object):
def __init__(self, application):
self.application = application
def __call__(self, environ, start_response):
length = int(environ.get('CONTENT_LENGTH') or 0)
body = environ['wsgi.input'].read(length)
environ['body_copy'] = body
# replace the stream since it was exhausted by read()
environ['wsgi.input'] = BytesIO(body)
return self.application(environ, start_response)
app.wsgi_app = WSGICopyBody(app.wsgi_app)
request.environ['body_copy']
go to project path set FLASK_APP=ABC.py SET FLASK_ENV=development
flask run -h [yourIP] -p 8080 you will following o/p on CMD:- * Serving Flask app "expirement.py" (lazy loading) * Environment: development * Debug mode: on * Restarting with stat * Debugger is active! * Debugger PIN: 199-519-700 * Running on http://[yourIP]:8080/ (Press CTRL+C to quit)
If you use Nginx behind other balancer, for instance AWS Application Balancer, HTTP_X_FORWARDED_FOR returns list of addresses. It can be fixed like that:
if 'X-Forwarded-For' in request.headers:
proxy_data = request.headers['X-Forwarded-For']
ip_list = proxy_data.split(',')
user_ip = ip_list[0] # first address in list is User IP
else:
user_ip = request.remote_addr # For local development
Here's an example of parsing posted JSON data and echoing it back.
from flask import Flask, request, jsonify
app = Flask(__name__)
@app.route('/foo', methods=['POST'])
def foo():
data = request.json
return jsonify(data)
To post JSON with curl:
curl -i -H "Content-Type: application/json" -X POST -d '{"userId":"1", "username": "fizz bizz"}' http://localhost:5000/foo
Or to use Postman:
Normally, you'd get an RST if you do a close which doesn't linger (i.e. in which data can be discarded by the stack if it hasn't been sent and ACK'd) and a normal FIN if you allow the close to linger (i.e. the close waits for the data in transit to be ACK'd).
Perhaps all you need to do is set your socket to linger so that you remove the race condition between a non lingering close done on the socket and the ACKs arriving?
According to the documentation, timestamp
is a synonym for rowversion
- it's automatically generated and guaranteed1 to be unique. datetime
isn't - it's just a data type which handles dates and times, and can be client-specified on insert etc.
1 Assuming you use it properly, of course. See comments.
try this
df.rename(columns={ df.columns[1]: "your value" }, inplace = True)
You need to install the Visual C++ libraries: http://www.microsoft.com/en-us/download/details.aspx?id=30679
As mentioned by Stuart McLaughlin, make sure you get the x86 version even if you use a 64-bits OS because PHP needs some 32-bit libraries.
wait.until(ExpectedConditions)
won't return null, it will either meet the condition or throw TimeoutException
.
You can check if the element is displayed and enabled
WebElement element = driver.findElement(By.xpath);
if (element.isDisplayed() && element.isEnabled()) {
element.click();
}
Additional to tomaskazemekas's answer: you should install spyder in that virtual environment by:
conda install -n myenv spyder
(on Windows, for Linux or MacOS, you can search for similar commands)
if you want to get the index values, you can simply do:
dataframe.index
this will output a pandas.core.index
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysql.sock' (2)
I get the error above when I try to log into MYSQL after installing it using brew, I am running MacOs, Oh yea I also noticed mysql is running I have restarted numerous times with no luck resolving the issue along with removing mysql and numerous reinstalls!
So simple I could slap myself, no but really, I solved this by CD into the temp folder that contains mysqlx.sock and mysql.sock.lock files, I deleted the single sock.lock file only and this solved my issue after doing so and I can log into mysql using the mysql -uroot command. Here are the commands I used. (this issue had me hung up for a while)
~ cd /tmp
/tmp ls
(this will list all the sock files in the temp folder, output shown below)
com.apple.launchd.8AgGW2s9Bb mysql.sock.lock
com.apple.launchd.batxrSISAJ mysqlx.sock
com.apple.launchd.cRCaxtT41m mysqlx.sock.lock
com.google.Keystone powerlog
then run
rm -R mysql.sock.lock
(use command above to remove the sock.lock file from the /tmp directory this resolved my issue)
hope this helped :)
FWIW,
Poor mans security folder (to protect a public shared folder from little prying eyes ;) )
mkdir -p {0..9}/{0..9}/{0..9}/{0..9}
Now you can put your files in a pin numbered folder. Not exactly waterproof, but it's a barrier for the youngest.
Since the frameborder
attribute is only necessary for IE, there is another way to get around the validator. This is a lightweight way that doesn't require Javascript or any DOM manipulation.
<!--[if IE]>
<iframe src="source" frameborder="0">?</iframe>
<![endif]-->
<!--[if !IE]>-->
<iframe src="source" style="border:none">?</iframe>
<!-- <![endif]-->
From this document, this DTU percent is determined by this query:
SELECT end_time,
(SELECT Max(v)
FROM (VALUES (avg_cpu_percent), (avg_data_io_percent),
(avg_log_write_percent)) AS
value(v)) AS [avg_DTU_percent]
FROM sys.dm_db_resource_stats;
looks like the max of avg_cpu_percent
, avg_data_io_percent
and avg_log_write_percent
Reference:
Having run both queries on a SQL Server 2012 instance, I can confirm the first query was fastest in my case.
The query with the LIKE
keyword showed a clustered index scan.
The CONTAINS
also had a clustered index scan with additional operators for the full text match and a merge join.
i have alreay 2 situations where directives and services/factories didnt play well.
the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).
in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.
i even tried to make a directive with a controller and an isolated-scope
only when i moved everything to a controller and it worked like magic.

you can not stop user from seeing our code but you can avoid it by disabling some keys
simply you can do <body oncontextmenu="return false" onkeydown="return false;" onmousedown="return false;"><!--Your body context--> </body>
After doing this following keys get disabled automatically

I often have a need to combine date values from one place with time values for another. I wrote a helper function to accomplish this.
let startDateTimeComponents = NSDateComponents()
startDateTimeComponents.year = NSCalendar.currentCalendar().components(NSCalendarUnit.Year, fromDate: date).year
startDateTimeComponents.month = NSCalendar.currentCalendar().components(NSCalendarUnit.Month, fromDate: date).month
startDateTimeComponents.day = NSCalendar.currentCalendar().components(NSCalendarUnit.Day, fromDate: date).day
startDateTimeComponents.hour = NSCalendar.currentCalendar().components(NSCalendarUnit.Hour, fromDate: time).hour
startDateTimeComponents.minute = NSCalendar.currentCalendar().components(NSCalendarUnit.Minute, fromDate: time).minute
let startDateCalendar = NSCalendar(identifier: NSCalendarIdentifierGregorian)
combinedDateTime = startDateCalendar!.dateFromComponents(startDateTimeComponents)!
On Mac OS X Lion, to set visualgc to run, I used:
export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
They are equivalent. See this code:
mySlice1 := make([]int, 0)
mySlice2 := []int{}
fmt.Println("mySlice1", cap(mySlice1))
fmt.Println("mySlice2", cap(mySlice2))
Output:
mySlice1 0
mySlice2 0
Both slices have 0
capacity which implies both slices have 0
length (cannot be greater than the capacity) which implies both slices have no elements. This means the 2 slices are identical in every aspect.
See similar questions:
What is the point of having nil slice and empty slice in golang?

Only redirection won't work, since there's nothing to connect the now-open file descriptors. So no, there is no way like this.

If you have to generate global variables in production code (which should be avoided) always declare them explicitly:
window.globalVar = "This is global!";
While it is possible to define a global variable by just omitting var
(assuming there is no local variable of the same name), doing so generates an implicit global, which is a bad thing to do and would generate an error in strict mode.
To escape a character in sql you can use !
:
EXAMPLE - USING ESCAPE CHARACTERS
It is important to understand how to "Escape Characters" when pattern matching. These examples deal specifically with escaping characters in Oracle.
Let's say you wanted to search for a % or a _ character in the SQL LIKE condition. You can do this using an Escape character.
Please note that you can only define an escape character as a single character (length of 1).
For example:
SELECT *
FROM suppliers
WHERE supplier_name LIKE '!%' escape '!';
This SQL LIKE condition example identifies the ! character as an escape character. This statement will return all suppliers whose name is %.
Here is another more complicated example using escape characters in the SQL LIKE condition.
SELECT *
FROM suppliers
WHERE supplier_name LIKE 'H%!%' escape '!';
This SQL LIKE condition example returns all suppliers whose name starts with H and ends in %. For example, it would return a value such as 'Hello%'.
You can also use the escape character with the _ character in the SQL LIKE condition.
For example:
SELECT *
FROM suppliers
WHERE supplier_name LIKE 'H%!_' escape '!';
This SQL LIKE condition example returns all suppliers whose name starts with H and ends in _ . For example, it would return a value such as 'Hello_'.

This issue should be fixed in the newest version of Homebrew. Try reinstalling it, which is described on the Homebrew home page.
I found that in my code when I used a ration or percentage for line-height line-height;1.5;
My page would scale in such a way that lower case font and upper case font would take up different page heights (I.E. All caps took more room than all lower). Normally I think this looks better, but I had to go to a fixed height line-height:24px;
so that I could predict exactly how many pixels each page would take with a given number of lines.
It depends on how you validate your XML. If you use XML Schema validation, the correct way of representing null
values is with the xsi:nil
attribute.

You could also insert the results (or top 10 results) into a temp table and get the columns from the temp table (as long as the column names are all different).
SELECT TOP 10 *
INTO #TempTable
FROM <DataSource>
Then use:
EXEC tempdb.dbo.sp_help N'#TempTable';
or
SELECT *
FROM tempdb.sys.columns
WHERE [object_id] = OBJECT_ID(N'tempdb..#TempTable');

A regular expression for words would give you the most control. You would want to carefully consider how to deal with words with dashes or apostrophes, like "I'm".
We're using SmartAssembly on our windows client. Works just fine.
Does add some extra problems too. Printing out your class names in log files/exceptions have to be de-obfuscated. And of course can't create a class from its name. So it's a good idea to take a look at your client and see which problems you can get by obfuscating.
Create a custom class, e.g. .custom-btn
. Note that to override jQM styles without using !important
, CSS hierarchy should be respected. .ui-btn.custom-class
or .ui-input-btn.custom-class
.
.ui-input-btn.custom-btn {
border:1px solid red;
text-decoration:none;
font-family:helvetica;
color:red;
background:url(img.png) repeat-x;
}
Add a data-wrapper-class
to input
. The custom class will be added to input
wrapping div.
<input type="button" data-wrapper-class="custom-btn">
Input
button is wrapped by a DIV with class ui-btn
. You need to select that div and the input[type="submit"]
. Using !important
is essential to override Jquery Mobile styles.
div.ui-btn, input[type="submit"] {
border:1px solid red !important;
text-decoration:none !important;
font-family:helvetica !important;
color:red !important;
background:url(../images/btn_hover.png) repeat-x !important;
}
On document load set the
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;
Here's how you convert numbers to strings, and join strings to other things (it's weird):
>> ['the number is ' num2str(15) '.']
ans =
the number is 15.
try this
SELECT group_name, employees, surveys, COUNT( surveys ) AS test1,
concat(round(( surveys/employees * 100 ),2),'%') AS percentage
FROM a_test
GROUP BY employees
I had an issue with Swedish/Norwegian letters showing up as question marks, despite having specified:
contentType: "application/json; charset=utf-8",
This was solved by adding encodeURIComponent
to the string.
url: "/set_comment.do?text=" + encodeURIComponent(comment),
So none of the above stuff worked for me. Except this: edit httpd.conf,
find the line
Listen 80
and change to
listen 0.0.0.0:80
if you are running windows 8, its got something to do with using ipv6 instead of ipv4
If you need to wrap a private method inside a transaction and don't want to use aspectj, you can use TransactionTemplate.
@Service
public class MyService {
@Autowired
private TransactionTemplate transactionTemplate;
private void process(){
transactionTemplate.execute(new TransactionCallbackWithoutResult() {
@Override
protected void doInTransactionWithoutResult(TransactionStatus status) {
processInTransaction();
}
});
}
private void processInTransaction(){
//...
}
}
The running the impdp command to produce an sqlfile, you will need to run it as a user which has the DATAPUMP_IMP_FULL_DATABASE role.
Or... run it as a low privileged user and use the MASTER_ONLY=YES option, then inspect the master table. e.g.
select value_t
from SYS_IMPORT_TABLE_01
where name = 'CLIENT_COMMAND'
and process_order = -59;
col object_name for a30
col processing_status head STATUS for a6
col processing_state head STATE for a5
select distinct
object_schema,
object_name,
object_type,
object_tablespace,
process_order,
duplicate,
processing_status,
processing_state
from sys_import_table_01
where process_order > 0
and object_name is not null
order by object_schema, object_name

As a rule, if your "underline" is not the same color as your text [and the 'color:' is not overridden inline] it is not coming from "text-decoration:" It has to be "border-bottom:"
Don't forget to take the border off your pseudo classes too!
a, a:link, a:visited, a:active, a:hover {border:0!important;}
This snippet assumes its on an anchor, change to it's wrapper accordingly... and use specificity instead of "!important" after you track down the root cause.
Your JavaScript is fine, unless you have other scripts running on this page which may corrupt everything. You may check this using Firebug.
I've now tested a bit and it really seems that ASP.net ignores disabled controls. Basically the postback is issued, but probably the framework ignores such events since it "assumes" that a disabled button cannot raise any postback and so it ignores possibly attached handlers. Now this is just my personal reasoning, one could use Reflector to check this in more depth.
As a solution you could really try to do the disabling at a later point, basically you delay the control.disabled = "disabled"
call using a JavaTimer or some other functionality. In this way 1st the postback to the server is issued before the control is being disabled by the JavaScript function. Didn't test this but it could work

I'm having exactly the same problem. The only workaround I've found, is to replace the fragments by a new instance, each time the tabs are changed.
ft.replace(R.id.fragment_container, Fragment.instantiate(PlayerMainActivity.this, fragment.getClass().getName()));
Not a real solution, but i haven't found a way to reuse the previous fragment instance...
The default parser can parse your input. So you don't need a custom formatter and
String dateTime = "2012-02-22T02:06:58.147Z";
ZonedDateTime d = ZonedDateTime.parse(dateTime);
works as expected.
and(re.search("bla_bla_pattern", str_item, re.IGNORECASE) == None)
is working.
You can use NullableValueTypes (like int?) for this. The code would be like this:
private void Example(int? arg1, int? arg2)
{
if(!arg1.HasValue)
{
//do something
}
if(!arg2.HasValue)
{
//do something else
}
}
map() and flatMap()
map()
Just takes a Function a lambda param where T is element and R the return element built using T. At the end we'll have a Stream with objects of Type R. A simple example can be:
Stream
.of(1,2,3,4,5)
.map(myInt -> "preFix_"+myInt)
.forEach(System.out::println);
It simply takes elements 1 to 5 of Type Integer
, uses each element to build a new element from type String
with value "prefix_"+integer_value
and prints it out.
flatMap()
It is useful to know that flatMap() takes a function F<T, R>
where
T is a type from which a Stream can be built from/with. It can be a List (T.stream()), an array (Arrays.stream(someArray)), etc.. anything that from which a Stream can be with/or form. in the example below each dev has many languages, so dev. Languages is a List and will use a lambda parameter.
R is the resulting Stream that will be built using T. Knowing that we have many instances of T, we will naturally have many Streams from R. All these Streams from Type R will now be combined into one single 'flat' Stream from Type R.
Example
The examples of Bachiri Taoufiq see its answer here are simple and easy to understanding. Just for clarity, let just say we have a team of developers:
dev_team = {dev_1,dev_2,dev_3}
, with each developer knowing many languages:
dev_1 = {lang_a,lang_b,lang_c},
dev_2 = {lang_d},
dev_2 = {lang_e,lang_f}
Applying Stream.map() on dev_team to get the languages of each dev:
dev_team.map(dev -> dev.getLanguages())
will give you this structure:
{
{lang_a,lang_b,lang_c},
{lang_d},
{lang_e,lang_f}
}
which is basically a List<List<Languages>> /Object[Languages[]]
. Not so very pretty, nor Java8-like!!
with Stream.flatMap()
you can 'flatten' things out as it takes the above structure
and turns it into {lang_a, lang_b, lang_c, lang_d, lang_e, lang_f}
, which can basically used as List<Languages>/Language[]/etc
...
so in the end, your code would make more sense like this:
dev_team
.stream() /* {dev_1,dev_2,dev_3} */
.map(dev -> dev.getLanguages()) /* {{lang_a,...,lang_c},{lang_d}{lang_e,lang_f}}} */
.flatMap(languages -> languages.stream()) /* {lang_a,...,lang_d, lang_e, lang_f} */
.doWhateverWithYourNewStreamHere();
or simply:
dev_team
.stream() /* {dev_1,dev_2,dev_3} */
.flatMap(dev -> dev.getLanguages().stream()) /* {lang_a,...,lang_d, lang_e, lang_f} */
.doWhateverWithYourNewStreamHere();
When to use map() and use flatMap():
Use map()
when each element of type T from your stream is supposed to be mapped/transformed to a single element of type R. The result is a mapping of type (1 start element -> 1 end element) and new stream of elements of type R is returned.
Use flatMap()
when each element of type T from your stream is supposed to mapped/transformed to a Collections of elements of type R. The result is a mapping of type (1 start element -> n end elements). These Collections are then merged (or flattened) to a new stream of elements of type R. This is useful for example to represent nested loops.
Pre Java 8:
List<Foo> myFoos = new ArrayList<Foo>();
for(Foo foo: myFoos){
for(Bar bar: foo.getMyBars()){
System.out.println(bar.getMyName());
}
}
Post Java 8
myFoos
.stream()
.flatMap(foo -> foo.getMyBars().stream())
.forEach(bar -> System.out.println(bar.getMyName()));
yes, it accepts the tuple of four arguments, if you have Number of training Images(or whatever)=6000, image size=28x28 and a grayscale image you'll have parameters as (6000,28,28,1)
the last argument is 1 for greyscale and 3 for color images.
Using subList(30, 38);
will fail because max index 38 is not available in list, so its not possible.
Only way may be before asking for the sublist, you explicitly determine the max index using list size() method.
for example, check size, which returns 35, so call sublist(30, size());
OR
COPIED FROM pb2q comment
dataList = dataList.subList(30, 38 > dataList.size() ? dataList.size() : 38);
you just need to reset dependencies in app.gradle file like old one as

Another weird subtle difference on GitHub is that changes to forks are not counted in your activity log until your changes are pulled into the original repo. What's more, to change a fork into a proper clone, you have to contact Github support, apparently.
From Why are my contributions not showing up:
Commit was made in a fork
Commits made in a fork will not count toward your contributions. To make them count, you must do one of the following:
Open a pull request to have your changes merged into the parent repository. To detach the fork and turn it into a standalone repository on GitHub, contact GitHub Support. If the fork has forks of its own, let support know if the forks should move with your repository into a new network or remain in the current network. For more information, see "About forks."
Use the str
accessor with square brackets:
df['col'] = df['col'].str[:9]
Or str.slice:
df['col'] = df['col'].str.slice(0, 9)
Since it is not possible to make an async constructor, I use a static async method that returns a class instance created by a private constructor. This is not elegant but it works ok.
public class ViewModel
{
public ObservableCollection<TData> Data { get; set; }
//static async method that behave like a constructor
async public static Task<ViewModel> BuildViewModelAsync()
{
ObservableCollection<TData> tmpData = await GetDataTask();
return new ViewModel(tmpData);
}
// private constructor called by the async method
private ViewModel(ObservableCollection<TData> Data)
{
this.Data = Data;
}
}
Recently I was also having this issue, then I contacted Google Support and they gave me this link to provide required info, I posted and within 24 hours my problem was fixed.

Use router-hook.
You can use the useRouter hook
in any component in your application.
https://nextjs.org/docs/api-reference/next/router#userouter
import Link from "next/link";
<Link href={{ pathname: '/search', query: { keyword: 'this way' } }}><a>path</a></Link>
Or
import Router from 'next/router'
Router.push({
pathname: '/search',
query: { keyword: 'this way' },
})
import { useRouter } from 'next/router'
export default () => {
const router = useRouter()
console.log(router.query);
...
}
Just add position:absolute; top:0; right:0;
to the CSS for your button.

Although this shouldn't be a bottle neck as branching issues on modern processors isn't normally a problem, but in the case of integers you could go for a branch-less solution as outlined here: http://graphics.stanford.edu/~seander/bithacks.html#IntegerAbs.
(x + (x >> 31)) ^ (x >> 31);
This does fail in the obvious case of Integer.MIN_VALUE however, so this is a use at your own risk solution.
Changed the set to remove % as that will write to text file as Echo on or off

Legible way using spread operator:
const reverseString = str => [...str].reverse().join('');
console.log(reverseString('ABC'));

Two ways:
Use indexes:
double sum = 0;
for(int i = 0; i < m.size(); i++)
sum += m.get(i);
return sum;
Use the "for each" style:
double sum = 0;
for(Double d : m)
sum += d;
return sum;
I tried all the things specified here and found yet another answer. I had to compile my application with 32-bit DLLs. I had built the libraries both in 32-bit and 64-bit but had my PATH
set to 64-bit libraries. After I recompiled my application (with a number of changes in my code as well) I got this dreaded error and struggled for two days. Finally, after trying a number of other things, I changed my PATH
to have the 32-bit DLLs before the 64-bit DLLs (they have the same names). And it worked. I am just adding it here for completeness.
I thought I'd extend the scope of this question a bit, with some useful tidbits on the matter.
In order to get the canvas as an image, you should do the following:
var canvas = document.getElementById("mycanvas");
var image = canvas.toDataURL("image/png");
You can use this to write the image to the page:
document.write('<img src="'+image+'"/>');
Where "image/png" is a mime type (png is the only one that must be supported). If you would like an array of the supported types you can do something along the lines of this:
var imageMimes = ['image/png', 'image/bmp', 'image/gif', 'image/jpeg', 'image/tiff']; //Extend as necessary
var acceptedMimes = new Array();
for(i = 0; i < imageMimes.length; i++) {
if(canvas.toDataURL(imageMimes[i]).search(imageMimes[i])>=0) {
acceptedMimes[acceptedMimes.length] = imageMimes[i];
}
}
You only need to run this once per page - it should never change through a page's lifecycle.
If you wish to make the user download the file as it is saved you can do the following:
var canvas = document.getElementById("mycanvas");
var image = canvas.toDataURL("image/png").replace("image/png", "image/octet-stream"); //Convert image to 'octet-stream' (Just a download, really)
window.location.href = image;
If you're using that with different mime types, be sure to change both instances of image/png, but not the image/octet-stream. It is also worth mentioning that if you use any cross-domain resources in rendering your canvas, you will encounter a security error when you try to use the toDataUrl method.
From all the answers above, Björn's answer seems to be the most elegant and short. I personally used this approach many times. MAX or MIN function will do the job equally well. Complete PL/SQL follows, just the where clause should be specified.
declare v_column my_table.column%TYPE;
begin
select MIN(column) into v_column from my_table where ...;
DBMS_OUTPUT.PUT_LINE('v_column=' || v_column);
end;
In my case I have declared a Bool
like this:
var isActivityOpen: Bool
i.e. I declared it without unwrapping so, This is how I solved the (no initializer) error :
var isActivityOpen: Bool!
You probably want to assign the lastname
you are reading out here
lastname = sheet.cell(row=r, column=3).value
to something; currently the program just forgets it
you could do that two lines after, like so
unpaidMembers[name] = lastname, email
your program will still crash at the same place, because .items()
still won't give you 3-tuples but rather something that has this structure: (name, (lastname, email))
good news is, python can handle this
for name, (lastname, email) in unpaidMembers.items():
etc.
Well, first you should parse the JSON string, so that you can easily access it's members:
var arr = $.parseJSON(str);
Use the map
method to extract the values:
arr = $.map(arr, function(o){ return o.y; });
Then you can use the array in the max
method:
var highest = Math.max.apply(this,arr);
Or as a one-liner:
var highest = Math.max.apply(this,$.map($.parseJSON(str), function(o){ return o.y; }));
I usually start with something like:
set lines 256
set trimout on
set tab off
Have a look at help set
if you have the help information installed. And then select name,address
rather than select *
if you really only want those two columns.
Be aware that this property isn't as useful as many people think it is. Just because your app is running on a Windows machine, for example, doesn't mean the file it's reading will be using Windows-style line separators. Many web pages contain a mixture of "\n" and "\r\n", having been cobbled together from disparate sources. When you're reading text as a series of logical lines, you should always look for all three of the major line-separator styles: Windows ("\r\n"), Unix/Linux/OSX ("\n") and pre-OSX Mac ("\r").
When you're writing text, you should be more concerned with how the file will be used than what platform you're running on. For example, if you expect people to read the file in Windows Notepad, you should use "\r\n" because it only recognizes the one kind of separator.
It all depends. Theoretically using a single column with 4 byte data type. You could store 300 000 rows. But there is probably alot of overhead in the database even before you do anything. I read some where that you could have 1.000.000 rows but again, it all depends..
You can also link databases together. Limiting yourself to only disk space.
If you want a vertical divider between 2 columns, all you need is add
class="col-6 border-left"
to one of your column div-s
BUT
In the world of responsive design, you may need to make it disappear sometimes.
The solution is disappearing <hr>
+ disappearing <div>
+ margin-left: -1px;
<div class="container">
<div class="row">
<div class="col-md-7">
1 of 2
</div>
<div class="border-left d-sm-none d-md-block" style="width: 0px;"></div>
<div class="col-md-5" style="margin-left: -1px;">

In Python whitespace is significant. The function ends when the indentation becomes smaller (less).
def f():
pass # first line
pass # second line
pass # <-- less indentation, not part of function f.
Note that one-line functions can be written without indentation, on one line:
def f(): pass
And, then there is the use of semi-colons, but this is not recommended:
def f(): pass; pass
The three forms above show how the end of a function is defined syntactically. As for the semantics, in Python there are three ways to exit a function:
Using the return
statement. This works the same as in any other imperative programming language you may know.
Using the yield
statement. This means that the function is a generator. Explaining its semantics is beyond the scope of this answer. Have a look at Can somebody explain me the python yield statement?
By simply executing the last statement. If there are no more statements and the last statement is not a return
statement, then the function exists as if the last statement were return None
. That is to say, without an explicit return
statement a function returns None
. This function returns None
:
def f():
pass
And so does this one:
def f():

From the docs of the flush
method:
Flushes the output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.
The buffering is mainly done to improve the I/O performance. More on this can be read from this article: Tuning Java I/O Performance.
Personally I think that passing the column as a string is pretty ugly. I like to do something like:
get.max <- function(column,data=NULL){
column<-eval(substitute(column),data, parent.frame())
max(column)
}
which will yield:
> get.max(mpg,mtcars)
[1] 33.9
> get.max(c(1,2,3,4,5))
[1] 5
Notice how the specification of a data.frame is optional. you can even work with functions of your columns:
> get.max(1/mpg,mtcars)
[1] 0.09615385

If you're just starting out learning javascript & don't want to spend time creating an entire webpage just for embedding test scripts, just open Dev Tools in a new tab in Chrome Browser, and click on Console
.
Then type out some test scripts: eg.
console.log('Aha!')
Then press Enter after every line (to submit for execution by Chrome)
or load your own "external script file":
document.createElement('script').src = 'http://example.com/file.js';
Then call your functions:
console.log(file.function('?????'))

If you have named tuples you can do this:
results = [t.age for t in mylist if t.person_id == 10]
Otherwise use indexes:
results = [t[1] for t in mylist if t[0] == 10]
Or use tuple unpacking as per Nate's answer. Note that you don't have to give a meaningful name to every item you unpack. You can do (person_id, age, _, _, _, _)
to unpack a six item tuple.

I know this thread is old, but still answering it so that no-one else should spend sleepless nights.
I was refactoring an old project, whose layout files all contained hardcoded
attributes such as android:maxLength = 500
. So I decided to register it in my
res/dimen
file as <dimen name="max_length">500</dimen>
.
Finished refactoring almost 30 layout files with my res-value. Guess what? the next time I ran my project it started throwing the same InflateException
.
As a solution, needed to redo my all changes and keep all-those values as same as before.
TLDR;
step 1: All running good.
step 2: To boost my maintenance I replaced android:maxLength = 500
with <dimen name="max_length">500</dimen>
and android:maxLength = @dimen/max_length
, that's where it all went wrong(crashing with InflateException
).
step 3: All running bad
step 4: Re-do all my work by again replacing android:maxLength = @dimen/max_length
with android:maxLength = 500
.Everything got fixed.
step 5: All running good.
Just go to Package Manage Console, type the following:
Enable-Migrations
*If the error like this appears "Unable to update database to match the current model because there are pending changes and automatic migration is disabled. Either write the pending model changes to a code-based migration or enable automatic migration."
Do this >>> Add-Migration
*Visual studio will ask for a name, kindly input the name you want.

If you really want to get the type by name you may use the following:
System.AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes()).First(x => x.Name == "theassembly");
Note that you can improve the performance of this drastically the more information you have about the type you're trying to load.

You can also create a function in PHP to convert an object array:
function object_to_array($object) {
return (array) $object;
}
In Bootstrap 3 they do not have separate classes for different styles of labels.
http://getbootstrap.com/components/
However, you can customize bootstrap classes that way. In your css file
.lb-sm {
font-size: 12px;
}
.lb-md {
font-size: 16px;
}
.lb-lg {
font-size: 20px;
}
Alternatively, you can use header tags to change the sizes. For example, here is a medium sized label and a small-sized label
<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<h3>Example heading <span class="label label-default">New</span></h3>_x000D_
<h6>Example heading <span class="label label-default">New</span></h6>
_x000D_
They might add size classes for labels in future Bootstrap versions.

If you have luasocket installed:

You can create a function with the pattern ShouldSerialize{PropertyName}
which tells the XmlSerializer if it should serialize the member or not.
For example, if your class property is called MyNullableInt
you could have
public bool ShouldSerializeMyNullableInt()
{
return MyNullableInt.HasValue;
}
Here is a full sample
public class Person
{
public string Name {get;set;}
public int? Age {get;set;}
public bool ShouldSerializeAge()
{
return Age.HasValue;
}
}
Serialized with the following code
Person thePerson = new Person(){Name="Chris"};
XmlSerializer xs = new XmlSerializer(typeof(Person));
StringWriter sw = new StringWriter();
xs.Serialize(sw, thePerson);
Results in the followng XML - Notice there is no Age
<Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Name>Chris</Name>
</Person>

Uploading files is actually possible with AJAX these days. Yes, AJAX, not some crappy AJAX wannabes like swf or java.
This example might help you out: https://webblocks.nl/tests/ajax/file-drag-drop.html
(It also includes the drag/drop interface but that's easily ignored.)
Basically what it comes down to is this:
<input id="files" type="file" />
<script>
document.getElementById('files').addEventListener('change', function(e) {
var file = this.files[0];
var xhr = new XMLHttpRequest();
(xhr.upload || xhr).addEventListener('progress', function(e) {
var done = e.position || e.loaded
var total = e.totalSize || e.total;
console.log('xhr progress: ' + Math.round(done/total*100) + '%');
});
xhr.addEventListener('load', function(e) {
console.log('xhr upload complete', e, this.responseText);
});
xhr.open('post', '/URL-HERE', true);
xhr.send(file);
});
</script>
(demo: http://jsfiddle.net/rudiedirkx/jzxmro8r/)
So basically what it comes down to is this =)
xhr.send(file);
Where file
is typeof Blob

Another (better IMO) way is to use FormData
. This allows you to 1) name a file, like in a form and 2) send other stuff (files too), like in a form.
var fd = new FormData;
fd.append('photo1', file);
fd.append('photo2', file2);
fd.append('other_data', 'foo bar');
xhr.send(fd);
FormData
makes the server code cleaner and more backward compatible (since the request now has the exact same format as normal forms).
All of it is not experimental, but very modern. Chrome 8+ and Firefox 4+ know what to do, but I don't know about any others.
This is how I handled the request (1 image per request) in PHP:
if ( isset($_FILES['file']) ) {
$filename = basename($_FILES['file']['name']);
$error = true;
// Only upload if on my home win dev machine
if ( isset($_SERVER['WINDIR']) ) {
$path = 'uploads/'.$filename;
$error = !move_uploaded_file($_FILES['file']['tmp_name'], $path);
}
$rsp = array(
'error' => $error, // Used in JS
'filename' => $filename,
'filepath' => '/tests/uploads/' . $filename, // Web accessible
);
echo json_encode($rsp);
exit;
}
You can use script like this for mac:
for f in $(curl -s -l -u user:pass ftp://your_ftp_server_ip/folder/)
do curl -O -u user:pass ftp://your_ftp_server_ip/folder/$f
done

I faced this error on outdated version of Visual Studio 2010. Due to project configuration I was not able to update this version to newer. Therefore, update of NuGet advised above did not fix things for me.
Root reason for the error in this and similar situations is in dependencies of the package you try to install, which are not compatible with .NET version available in your project.
Universal solution is not obligatory update of Visual Studio or .NET but in installation of older NuGet versions of the same package compatible with your system.
It is not possible to tell for sure, which of earlier versions will work. In my case, this command installed the package without any NuGet updates.
Install-Package X -Version [compatible version number]
To set precision for double values DecimalFormat
is good technique. To use this class import java.text.DecimalFormat
and create object of it for example
double no=12.786;
DecimalFormat dec = new DecimalFormat("#0.00");
System.out.println(dec.format(no));
So it will print two digits after decimal point here it will print 12.79
The sessions parameter is derived from the processes parameter and changes accordingly when you change the number of max processes. See the Oracle docs for further info.

JSON is perfectly capable of expressing lists of integers, and the JSON you have posted is valid. You can simply separate the integers by commas:

"Description": "1.99",
"ItemModList": [42, 47, 139]
}
You have included a dependency on the SLF4J API, which is what you use in your application for logging, but you must also include an implementation that does the real logging work.
For example to log through Log4J you would add this dependency:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.5.2</version>
</dependency>
The recommended implementation would be logback-classic, which is the successor of Log4j, made by the same guys that made SLF4J and Log4J:
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>0.9.24</version>
</dependency>
Note: The versions may be incorrect.
TJ's answer is excellent but I ran into one scenario where my HTML was already rendered and the document.write script would overwrite all of the page contents with just the date year.

</span>
Company Name

I was not able to get the createReadStream/createWriteStream
method working for some reason, but using the fs-extra npm module it worked right away. I am not sure of the performance difference though.
npm install --save fs-extra
var fs = require('fs-extra');
fs.copySync(path.resolve(__dirname, './init/xxx.json'), 'xxx.json');
You were close:
if (typeof a_string === 'string') {
// this is a string
}
On a related note: the above check won't work if a string is created with new String('hello')
as the type will be Object
instead. There are complicated solutions to work around this, but it's better to just avoid creating strings that way, ever.
The following link explains filters in Angular extremely well. It shows how it is possible to define custom sort logic within an ng-repeat. http://toddmotto.com/everything-about-custom-filters-in-angular-js
For sorting object with properties, this is the code I have used: (Note that this sort is the standard JavaScript sort method and not specific to angular) Column Name is the name of the property on which sorting is to be performed.
self.myArray.sort(function(itemA, itemB) {
if (self.sortOrder === "ASC") {
return itemA[columnName] > itemB[columnName];
} else {
return itemA[columnName] < itemB[columnName];
}
});
Just use Spring type ClassPathResource.
File file = new ClassPathResource("countries.xml").getFile();
As long as this file is somewhere on classpath Spring will find it. This can be src/main/resources
during development and testing. In production, it can be current running directory.
EDIT: This approach doesn't work if file is in fat JAR. In such case you need to use:
InputStream is = new ClassPathResource("countries.xml").getInputStream();
// using recursive approach and in one line
const fib = x => (x <= 1)? x : fib (x - 1) + fib(x -2);
fib(15); // 610
// display the 15 first
Array.from({ length: 15 }, (v, i) => fib(i));
// [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377]
// using memoization approach
function fibonacci(num, memo) {
memo = memo || {};
if (memo[num]) return memo[num];
if (num === 0) return 0;
if (num === 1) return 1;
return memo[num] = fibonacci(num - 1, memo) + fibonacci(num - 2, memo);
}
fibonacci(15); // 610
// display the 15 first
Array.from({ length: 15 }, (v, i) => fibonacci(i));
// [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377]
Check out the Node js modules wiki page. They have listed all the templating engines supporting node.js.
You can use the following code :
<!DOCTYPE html>
<html>
<body onLoad="triggerJS();">
<script>
function triggerJS(){
location.replace("http://www.google.com");
/*
location.assign("New_WebSite_Url");
//Use assign() instead of replace if you want to have the first page in the history (i.e if you want the user to be able to navigate back when New_WebSite_Url is loaded)
*/
}
</script>
</body>
</html>

To get this to work for me I had to drill down in the Python directory using the Python command prompt (on WIN10 from VS CODE). In my case it was in my "AppData\Local\Programs\Python\python35-32" directory. From there now I ran the command...
python -m pip install --upgrade pip
This worked and I'm good to go.
I am not an expert in the JS compiling business, but it makes sense to say, that v8 makes use from the const flag
Normally a after declaring and changing a bunch of variables, the memory gets fragmented, and v8 is stopping to execute, makes a pause some time of a few seconds, to make gc, or garbage collection.
if a variable is declared with const v8 can be confident to put it in a tight fixed size container between other const variables, since it will never change. It can also save the proper operations for that datatypes since the type will not change.
SELECT count(*) -- or count(myCol)
FROM <table name> -- replace <table name> with your table
WHERE myCol = true;
Here's a way with Windowing Function:
SELECT DISTINCT *, count(*) over(partition by myCol)
FROM <table name>;
-- Outputs:
-- --------------
-- myCol | count
-- ------+-------
-- f | 2
-- t | 3
-- | 1
You can register a class for your UITableViewCell
like this:
With Swift 3+:
self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
With Swift 2.2:
self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")
Make sure same identifier "cell
" is also copied at your storyboard's UITableViewCell
.
"self
" is for getting the class use the class name followed by .self
.
You could use a character class ([./-]
) so that the seperators can be any of the defined characters
var dateReg = /^\d{2}[./-]\d{2}[./-]\d{4}$/
Or better still, match the character class for the first seperator, then capture that as a group ([./-])
and use a reference to the captured group \1
to match the second seperator, which will ensure that both seperators are the same:
var dateReg = /^\d{2}([./-])\d{2}\1\d{4}$/
"22-03-1981".match(dateReg) // matches
"22.03-1981".match(dateReg) // does not match
"22.03.1981".match(dateReg) // matches
String UrlPath="android.resource://"+getPackageName()+"/"+R.raw.ur file name;
videocontainer.setVideoURI(Uri.parse(UrlPath));
videocontainer.start();
where videocontainer of type videoview.
The easiest method to install Android Studio (or any other developer tool) on Ubuntu is to use the snap package from Ubuntu Software store. No need to download Android Studio as zip, try to manually install it, add PPAs or fiddle with Java installation. The snap package bundles the latest Android Studio along with OpenJDK and all the necessary dependencies.
Search "android studio" in Ubuntu Software, select the first entry that shows up and install it:
Or if you prefer the command line way, run this in Terminal:
sudo snap install --classic android-studio
Open the newly installed Android Studio from dashboard:
Don't need to import anything if this is the first time you're installing it:
The Setup Wizard'll guide you through installation:
Select Standard install to get the latest SDK and Custom in-case you wanna change the SDK version or its install location. From here on, it's pretty straightforward, just click next-next and you'll have the SDK downloaded and installed.
This step might be useful if you want Android SDK's developer tool commands like adb, fastboot, aapt, etc available in Terminal. Might be needed by 3rd party dev platforms like React Native, Ionic, Cordova, etc and other tools too. For setting PATHs, edit your ~/.profile
file:
gedit ~/.profile
and then add the following lines to it:
# Android SDK Tools PATH
export ANDROID_HOME=${HOME}/Android/Sdk
export PATH="${ANDROID_HOME}/tools:${PATH}"
export PATH="${ANDROID_HOME}/emulator:${PATH}"
export PATH="${ANDROID_HOME}/platform-tools:${PATH}"
If you changed SDK location at the end of Step 2, don't forget to change the line export ANDROID_HOME=${HOME}/Android/Sdk
accordingly. Do a restart (or just logout and then log back in) for the PATHs to take effect.
Tested on Ubuntu 16.04LTS and above. Would work on 14.04LTS too if you install support for snap packages first.
Note: This question is similar to the AskUbuntu question "How to install Android Studio on Ubuntu?" and my answer equally applies. I'm reproducing my answer here to ensure a full complete answer exists rather than just a link.
I solved this problem using the following section of code before the second query:
...first query
while (_dbContext.Connection.State != System.Data.ConnectionState.Closed)
{
System.Threading.Thread.Sleep(500);
}
...second query
you can change the time of sleep in miliseconds
P.D. Useful when using threads
If you want to use only one SQL query to delete all tables you can use this:
EXEC sp_MSforeachtable @command1 = "DROP TABLE ?"
This is a hidden Stored Procedure in sql server, and will be executed for each table in the database you're connected.
Note: You may need to execute the query a few times to delete all tables due to dependencies.
Note2: To avoid the first note, before running the query, first check if there foreign keys relations to any table. If there are then just disable foreign key constraint by running the query bellow:
EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"
Under the help menu, there should be a menu item labeled "About Eclipse" I can't say with absolute precision because I'm using STS which is the same thing but my label is different.
In the dialog box that opens after you click the relevant about menu item there should be an installation details button in the lower left hand corner.
The version of Java that you're running Eclipse against ought to be in "System properties:" under the "Configuration" tab.
As of iOS 9.0 there's no way to get the orientation reliably. This is the code I used for an app I design for only portrait mode, so if the app is opened in landscape mode it will still be accurate:
screenHeight = [[UIScreen mainScreen] bounds].size.height;
screenWidth = [[UIScreen mainScreen] bounds].size.width;
if (screenWidth > screenHeight) {
float tempHeight = screenWidth;
screenWidth = screenHeight;
screenHeight = tempHeight;
}
This works for me :D
@Override
public void onResume() {
super.onResume();

public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK){
// handle back button's click listener
return true;

return false;
}
});}
I generally like to merge master
into the development
first so that if there are any conflicts, I can resolve in the development
branch itself and my master
remains clean.
(on branch development)$ git merge master
(resolve any merge conflicts if there are any)
git checkout master
git merge development (there won't be any conflicts now)
There isn't much of a difference in the two approaches, but I have noticed sometimes that I don't want to merge the branch into master
yet, after merging them, or that there is still more work to be done before these can be merged, so I tend to leave master
untouched until final stuff.
EDIT: From comments
If you want to keep track of who did the merge and when, you can use --no-ff
flag while merging to do so. This is generally useful only when merging development
into the master
(last step), because you might need to merge master
into development
(first step) multiple times in your workflow, and creating a commit node for these might not be very useful.
git merge --no-ff development
Just to share this from solutions on GitHub, this was the popular answer:
https://github.com/twbs/bootstrap/issues/9013#issuecomment-39698247
$(document).on('click','.navbar-collapse.in',function(e) {
if( $(e.target).is('a') ) {
$(this).collapse('hide');
}
});
This is wired to the document, so you don't have to do it on ready() (you can dynamically append links to your menu and it will still work), and it only gets called if the menu is already expanded. Some people have reported weird flashing where the menu opens and then immediately closes with other code that did not verify that the menu had the "in" class.
[UPDATE 2014-11-04] apparently when using sub-menus, the above can cause problems, so the above got modified to:
$(document).on('click','.navbar-collapse.in',function(e) {
if( $(e.target).is('a:not(".dropdown-toggle")') ) {
$(this).collapse('hide');
}
});
You can do it using jQuery. Example:
<script src="https://code.jquery.com/jquery-1.11.2.min.js"></script>
<script>
$.ajax({
url : "next.php",
type: "POST",
data : "name=Denniss",
success: function(data)
{
//data - response from server
$('#response_div').html(data);
}
});
</script>
I no longer work on Android project for a while. Although the below provides some clue to how an android studio project can be configured, but I can't guarantee it works flawlessly.
In principle, IntelliJ respects the build file and will try to use it to configure the IDE project. It's not true in the other way round, IDE changes normally will not affect the build file.
Since most Android projects are built by Gradle, it's always a good idea to understand this tool.
I'd suggest referring to @skyfishjy's answer, as it seems to be more updated than this one.
The below is not updated
Although android studio is based on IntelliJ IDEA, at the same time it relies on gradle to build your apk. As of 0.2.3, these two doesn't play nicely in term of configuring from GUI. As a result, in addition to use the GUI to setup dependencies, it will also require you to edit the build.gradle file manually.
Assuming you have a Test Project > Test structure. The build.gradle file you're looking for is located at TestProject/Test/build.gradle
Look for the dependencies section, and make sure you have
compile 'com.android.support:support-v4:13.0.+'
Below is an example.
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.5.+'
}
}
apply plugin: 'android'
repositories {
mavenCentral()
}
dependencies {
compile 'com.android.support:support-v4:13.0.+'
}
android {
compileSdkVersion 18
buildToolsVersion "18.0.1"
defaultConfig {
minSdkVersion 7
targetSdkVersion 16
}
}
You can also add 3rd party libraries from the maven repository
compile group: 'com.google.code.gson', name: 'gson', version: '2.2.4'
The above snippet will add gson 2.2.4 for you.
In my experiment, it seems that adding the gradle will also setup correct IntelliJ dependencies for you.
I think the problem is that the week
calculation somehow uses the first day of the year. I don't understand the internal mechanics, but you can see what I mean with this example:
library(data.table)
dd <- seq(as.IDate("2013-12-20"), as.IDate("2014-01-20"), 1)
# dd <- seq(as.IDate("2013-12-01"), as.IDate("2014-03-31"), 1)
dt <- data.table(i = 1:length(dd),
day = dd,
weekday = weekdays(dd),
day_rounded = round(dd, "weeks"))
## Now let's add the weekdays for the "rounded" date
dt[ , weekday_rounded := weekdays(day_rounded)]
## This seems to make internal sense with the "week" calculation
dt[ , weeknumber := week(day)]
dt
i day weekday day_rounded weekday_rounded weeknumber

i day weekday day_rounded weekday_rounded weeknumber
My workaround is this function: https://github.com/geneorama/geneorama/blob/master/R/round_weeks.R
round_weeks <- function(x){
require(data.table)
dt <- data.table(i = 1:length(x),
day = x,
weekday = weekdays(x))
offset <- data.table(weekday = c('Sunday', 'Monday', 'Tuesday', 'Wednesday',
'Thursday', 'Friday', 'Saturday'),
offset = -(0:6))
dt <- merge(dt, offset, by="weekday")
dt[ , day_adj := day + offset]
setkey(dt, i)
return(dt[ , day_adj])
}
Of course, you can easily change the offset to make Monday first or whatever. The best way to do this would be to add an offset to the offset... but I haven't done that yet.
I provided a link to my simple geneorama package, but please don't rely on it too much because it's likely to change and not very documented.
I Just came across to a similar to this question solution with included some performance statistics.
It seems that example below is faster:
document.getElementById('container').insertAdjacentHTML('beforeend', '<div id="idChild"> content html </div>');

InnerHTML vs jQuery 1 vs appendChild vs innerAdjecentHTML.
Reference: 1) Performance stats 2) API - insertAdjacentHTML

Simple is cheap in web development. I recommend using empty string when removing a particular style
$(element).style.attr = ' ';
I used to be irked by this problem; and I used to have a macro-cum-wrapper-function solution just like in Talonmies and Jared's answers, but, honestly? It makes using the CUDA Runtime API even more ugly and C-like.
So I've approached this in a different and more fundamental way. For a sample of the result, here's part of the CUDA vectorAdd
sample - with complete error checking of every runtime API call:
// (... prepare host-side buffers here ...)
auto current_device = cuda::device::current::get();
auto d_A = cuda::memory::device::make_unique<float[]>(current_device, numElements);
auto d_B = cuda::memory::device::make_unique<float[]>(current_device, numElements);
auto d_C = cuda::memory::device::make_unique<float[]>(current_device, numElements);
cuda::memory::copy(d_A.get(), h_A.get(), size);
cuda::memory::copy(d_B.get(), h_B.get(), size);
// (... prepare a launch configuration here... )
cuda::launch(vectorAdd, launch_config,
d_A.get(), d_B.get(), d_C.get(), numElements
);
cuda::memory::copy(h_C.get(), d_C.get(), size);
// (... verify results here...)
Again - all potential errors are checked , and an exception if an error occurred (caveat: If the kernel caused some error after launch, it will be caught after the attempt to copy the result, not before; to ensure the kernel was successful you would need to check for error between the launch and the copy with a cuda::outstanding_error::ensure_none()
command).
The code above uses my
Thin Modern-C++ wrappers for the CUDA Runtime API library (Github)
Note that the exceptions carry both a string explanation and the CUDA runtime API status code after the failing call.
A few links to how CUDA errors are automagically checked with these wrappers:
1.
long date = curDateFld.getDate();
//convert long to string
String str = String.valueOf(date);
//convert string to long
date = Long.valueOf(str);
2.
//convert long to string just concat long with empty string
String str = ""+date;
//convert string to long
date = Long.valueOf(str);
I know it's not exactly what you are looking for, but maybe it'll help you.
You can try use a jQuery selector :contains()
, add a class and then do a normal style for a class.
Just to sum up, I also faced exactly same problem. After reading a lot of stackoverflow posts and online blogs, the final solution which worked for me is this:
1) PostgreSQL(development or any stable version) should be installed before installing psycopg2.
2) The pg_config file (this file normally resides in the bin folder of the PostgreSQL installation folder) PATH had to be explicitly setup before installing psycopg2. In my case, the installation PATH for PostgreSQL is:
/opt/local/lib/postgresql91/
so in order to explicitly set the PATH of pg_config file, I entered following command in my terminal:
PATH=$PATH:/opt/local/lib/postgresql91/bin/
This command ensures that when you try to pip install psycopg2, it would find the PATH to pg_config automatically this time.
I have also posted a full error with trace and its solution on my blog which you may want to refer. Its for Mac OS X but the pg_config PATH problem is generic and applicable to Linux also.

I faced similar issue while doing svn update.
The approach which worked for me is to rename C:\Users\user\AppData\Roaming\TortoiseSVN folder to TortoiseSVN_bkp folder and then tried svn update again. This time I was able to connect to repository and it got updated.
Are you using standards mode? This solution depends on it I think.
If you're trying to make 2 columns you could do something like this:
<div id="outer">
<div id="left">
sidebar
</div>
<div id="main">
lorem ispsum etc...
</div>
</div>
Then use CSS to style it:
div#outer
{
width:100%;
height: 500px;
}
div#left
{
width: 100px;
height: 100%;
float:left;
background: green;
}
div#main
{
width: auto;
margin-left: 100px; /* same as div#left width */
height: 100%;
background:red;
}
If you don't want 2 columns you can probably remove <div id="left">
If you have to use the older client, here is my experience.
We are running a 32bit server so the development machines run the 32bit client. We run the 11.1 install, 11.2 gets the error. Once you have installed the 11.2 version you have to manually delete the files Oracle.Web.dll
and System.Data.OracleClient.dll
from the %windir%\Microsoft.NET\Framework\v2.0.50727
, reinstall 11.1, then register the dlls with gacutil.exe
.
This fixed the issue with my systems.
What you could do is, a validation of the values, for example:
if the value of the input of fullanme is greater than some value length and if the value of the input of address is greater than some value length then redirect to a new page, otherwise shows an error for the input.
// We access to the inputs by their id's
let fullname = document.getElementById("fullname");
let address = document.getElementById("address");
// Error messages
let errorElement = document.getElementById("name_error");
let errorElementAddress = document.getElementById("address_error");
// Form
let contactForm = document.getElementById("form");
// Event listener
contactForm.addEventListener("submit", function (e) {
let messageName = [];
let messageAddress = [];
if (fullname.value === "" || fullname.value === null) {
messageName.push("* This field is required");
}
if (address.value === "" || address.value === null) {
messageAddress.push("* This field is required");
}
// Statement to shows the errors
if (messageName.length || messageAddress.length > 0) {
e.preventDefault();
errorElement.innerText = messageName;
errorElementAddress.innerText = messageAddress;
}
// if the values length is filled and it's greater than 2 then redirect to this page
if (
(fullname.value.length > 2,
address.value.length > 2)
) {
e.preventDefault();
window.location.assign("https://www.google.com");
}
});

using as will return null if not a valid cast which allows you to do other things besides wrapping the cast in a try/catch. I hate classic cast. I always use as cast if i'm not sure. Plus, exceptions are expensive. Null checks are not.
In my case the error was very misleading. The problem was that PHPMyAdmin uses "ALTER TABLE" when you click on the "make unique" button instead of "ALTER IGNORE TABLE", so I had to do it manually, like in:
ALTER TABLE mytbl ADD UNIQUE (columnName);
As others pointed out, this message is coming from your shell prompt. The problem is that in a freshly created repository HEAD
(.git/HEAD
) points to a ref that doesn't exist yet.
% git init test
Initialized empty shared Git repository in /Users/jhelwig/tmp/test/.git/
% cd test
% cat .git/HEAD
ref: refs/heads/master
% ls -l .git/refs/heads
total 0
% git rev-parse HEAD
HEAD
fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions
It looks like rev-parse
is being used without sufficient error checking before-hand. After the first commit has been created .git/refs/heads
looks a bit different and git rev-parse HEAD
will no longer fail.
% ls -l .git/refs/heads

In the function that updates the Git information for the rest of my shell prompt (heavily modified version of wunjo prompt theme for ZSH), I have the following to get around this:
zgit_info_update() {
zgit_info=()
local gitdir=$(git rev-parse --git-dir 2>/dev/null)
if [ $? -ne 0 ] || [ -z "$gitdir" ]; then
return
fi
# More code ...
}
s.erase(std::remove(s.begin(), s.end(), '\n'), s.end());
if ( $('#myfav').children().length > 0 ) {
// do something
}
This should work. The children()
function returns a JQuery object that contains the children. So you just need to check the size and see if it has at least one child.
I've tried all the possibilities. Nothing worked for me except the following. var element = document.querySelectorAll("input[id=btn1]"); element[0].setAttribute("disabled",true);
You can also use ngIf
if the situation permits:
<div ng-repeat="p in [
{ name: 'Justin' },
{ name: 'Jimi' },
{ name: 'Bob' }
]" ng-if="['Jimi', 'Bob'].indexOf(e.name) > -1">
{{ p.name }} is cool
</div>
You could use jsonic for to serialize pretty much anything to JSON:
https://github.com/OrrBin/Jsonic
Example:
class TestClass:
def __init__(self):
self.x = 1
self.y = 2
instance = TestClass()
s = serialize(instance): # instance s set to: {"x":1, "y":2}
d = deserialize(s) # d is a new class instance of TestClass
pythonic has some nice features like declaring class attributes transient and type safe deserialization.
(A few years late with the answer, but i think it might help others)
Any checkout of a commit that is not the name of one of your branches will get you a detached HEAD. A SHA1 which represents the tip of a branch still gives a detached HEAD. Only a checkout of a local branch name avoids that mode.
See committing with a detached HEAD
When HEAD is detached, commits work like normal, except no named branch gets updated. (You can think of this as an anonymous branch.)
For example, if you checkout a "remote branch" without tracking it first, you can end up with a detached HEAD.
See git: switch branch without detaching head
Meaning: git checkout origin/main
(or origin/master
in the old days) would result in:
Note: switching to 'origin/main'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:
git switch -
Turn off this advice by setting config variable advice.detachedHead to false
HEAD is now at a1b2c3d My commit message
That is why you should not use git checkout
anymore, but the new git switch
command.
With git switch
, the same attempt to "checkout" (switch to) a remote branch would fail immediately:
git switch origin/main
fatal: a branch is expected, got remote branch 'origin/main'
To add more on git switch
:
With Git 2.23 (August 2019), you don't have to use the confusing git checkout
command anymore.
git switch
can also checkout a branch, and get a detach HEAD, except:
--detach
optionTo check out commit
HEAD~3
for temporary inspection or experiment without creating a new branch:git switch --detach HEAD~3 HEAD is now at 9fc9555312 Merge branch 'cc/shared-index-permbits'
See:
C:\Users\vonc\arepo>git checkout origin/master
Note: switching to 'origin/master'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
Vs. using the new git switch
command:
C:\Users\vonc\arepo>git switch origin/master
fatal: a branch is expected, got remote branch 'origin/master'
If you wanted to create a new local branch tracking a remote branch:
git switch <branch>
If
<branch>
is not found but there does exist a tracking branch in exactly one remote (call it<remote>
) with a matching name, treat as equivalent togit switch -c <branch> --track <remote>/<branch>
No more mistake!
No more unwanted detached HEAD!
I found out a crazy solution for dealing with this issue of checkbox not checked or checked here is my algorithm... create a global variable lets say var check_holder
check_holder has 3 states
If the checkbox is clicked,
$(document).on("click","#check",function(){
if(typeof(check_holder)=="undefined"){
//this means that it is the first time and the check is going to be checked
//do something
check_holder=1; //indicates that the is checked,it is in checked state
}
else if(check_holder==1){
//do something when the check is going to be unchecked
check_holder=0; //it means that it is not checked,it is in unchecked state
}
else if(check_holder==0){
//do something when the check is going to be checked
check_holder=1;//indicates that it is in a checked state
}
});
The code above can be used in many situation to find out if a checkbox has been checked or not checked. The concept behind it is to save the checkbox states in a variable, ie when it is on,off. i Hope the logic can be used to solve your problem.
The $@
variable expands to all command-line parameters separated by spaces. Here is an example.
abc "$@"
When using $@
, you should (almost) always put it in double-quotes to avoid misparsing of arguments containing spaces or wildcards (see below). This works for multiple arguments. It is also portable to all POSIX-compliant shells.
It is also worth nothing that $0
(generally the script's name or path) is not in $@
.
The Bash Reference Manual Special Parameters Section says that $@
expands to the positional parameters starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is "$@"
is equivalent to "$1" "$2" "$3"...
.
If you want to pass all but the first arguments, you can first use shift
to "consume" the first argument and then pass "$@"
to pass the remaining arguments to another command. In bash (and zsh and ksh, but not in plain POSIX shells like dash), you can do this without messing with the argument list using a variant of array slicing: "${@:3}"
will get you the arguments starting with "$3"
. "${@:3:4}"
will get you up to four arguments starting at "$3"
(i.e. "$3" "$4" "$5" "$6"
), if that many arguments were passed.
"$*"
gives all of the arguments stuck together into a single string (separated by spaces, or whatever the first character of $IFS
is). This looses the distinction between spaces within arguments and the spaces between arguments, so is generally a bad idea. Although it might be ok for printing the arguments, e.g. echo "$*"
, provided you don't care about preserving the space within/between distinction.
Assigning the arguments to a regular variable (as in args="$@"
) mashes all the arguments together just like "$*"
does. If you want to store the arguments in a variable, use an array with args=("$@")
(the parentheses make it an array), and then reference them as e.g. "${args[0]}"
etc (note that bash array indexes start at 0, so $1
will be in args[0]
, etc).
Leaving off the double-quotes, with either $@
or $*
, will try to split each argument up into separate words (based on whitespace or whatever's in $IFS
), and also try to expand anything that looks like a filename wildcard into a list of matching filenames. This can have really weird effects, and should almost always be avoided.
Try declaring the unit of width:
e1.style.width = "400px"; // width in PIXELS
Enums are put into the typescript language to define a set of named constants. Using enums can make our life easier. The reason for this is that these constants are often easier to read than the value which the enum represents.
enum Direction {
Up = 1,
Down,
Left,
Right,
}
This example from the typescript docs explains very nicely how enums work. Notice that our first enum value (Up) is initialized with 1. All the following members of the number enum are then auto incremented from this value (i.e. Down = 2, Left = 3, Right = 4). If we didn't initialize the first value with 1 the enum would start at 0 and then auto increment (i.e. Down = 1, Left = 2, Right = 3).
We can access the values of the enum in the following manner:
Direction.Up; // first the enum name, then the dot operator followed by the enum value
Direction.Down;
Notice that this way we are much more descriptive in the way we write our code. Enums basically prevent us from using magic numbers (numbers which represent some entity because the programmer has given a meaning to them in a certain context). Magic numbers are bad because of the following reasons:
Found under "app/code/core/Mage/Page/Block/Html/Header.php":
public function getWelcome()
{
if (empty($this->_data['welcome'])) {
if (Mage::app()->isInstalled() && Mage::getSingleton('customer/session')->isLoggedIn()) {
$this->_data['welcome'] = $this->__('Welcome, %s!', Mage::getSingleton('customer/session')->getCustomer()->getName());
} else {
$this->_data['welcome'] = Mage::getStoreConfig('design/header/welcome');
}
}
return $this->_data['welcome'];
}
So it looks like Mage::getSingleton('customer/session')->getCustomer()
will get your current logged in customer ;)
To get the currently logged in admin:
Mage::getSingleton('admin/session')->getUser();
eFox's answer worked for a single project, but not when I was referencing a module from another one (the pom.xml were still stored in my .m2
with the property instead of the version).
However, it works if you combine it with the flatten-maven-plugin
, since it generates the poms with the correct version, not the property.
The only option I changed in the plug-in definition is the outputDirectory
, it's empty by default, but I prefer to have it in target
, which is set in my .gitignore
configuration:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>flatten-maven-plugin</artifactId>
<version>1.0.1</version>
<configuration>
<updatePomFile>true</updatePomFile>
<outputDirectory>target</outputDirectory>
</configuration>
<executions>
<execution>
<id>flatten</id>
<phase>process-resources</phase>
<goals>
<goal>flatten</goal>
</goals>
</execution>
</executions>
</plugin>
The plug-in configuration goes in the parent pom.xml
(num1>=num2)*num1+(num2>num1)*num2
will return the maximum of two values.

now this will look for index.html file if not found it will look for index.php.
You can create file .gitignore and then Idea will suggest you install plugin
Use assets like a filesystem to dump any kind of files. And use res to store what it is made for, layouts, images, values.
Try this one, I test it, working fine
Date date = null;
String str = "2012/07/25 12:00:00";
DateFormat formatter = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
date = formatter.parse(str);
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
calendar.add(Calendar.HOUR, 2);
System.out.println(calendar.getTime()); // Output : Wed Jul 25 14:00:00 IST 2012
If you want to convert in your input type than add this code also
formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
str=formatter.format(calendar.getTime());
System.out.println(str); // Output : 2012-07-25 14:00:00
On Linux/Unix servers, you can execute a job in the background by using proc_open:
$descriptorspec = array(
array('pipe', 'r'), // stdin
array('file', 'myfile.txt', 'a'), // stdout
array('pipe', 'w'), // stderr
);
$proc = proc_open('php email_script.php &', $descriptorspec, $pipes);
The &
being the important bit here. The script will continue even if the original script has ended.
The root.after(ms, func) is the method you need to use. Just call it once before the mainloop starts and reschedule it inside the bound function every time it is called. Here is an example:
from tkinter import *
import time
def update_clock():
timer_label.config(text=time.strftime('%H:%M:%S',time.localtime()),
font='Times 25') # change the text of the time_label according to the current time
root.after(100, update_clock) # reschedule update_clock function to update time_label every 100 ms
root = Tk() # create the root window
timer_label = Label(root, justify='center') # create the label for timer
timer_label.pack() # show the timer_label using pack geometry manager
root.after(0, update_clock) # schedule update_clock function first call
root.mainloop() # start the root window mainloop
<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>
Easy as that.
Or without JS
<a href="http://yahoo.com" target="_blank">test</a>
You could stil use @TEMP
if you quote the identifier "@TEMP"
:
declare @TEMP table (ID int, Name varchar(max));
insert into @temp SELECT 1 AS ID, 'a' Name;

You might look at "Efficiently Enumerating the Subsets of a Set", which describes an algorithm to do part of what you want - quickly generate all subsets of N characters from length x to y. It contains an implementation in C.
For each subset, you'd still have to generate all the permutations. For instance if you wanted 3 characters from "abcde", this algorithm would give you "abc","abd", "abe"... but you'd have to permute each one to get "acb", "bac", "bca", etc.
From the keytool man - it imports certificate chain, if input is given in PKCS#7 format, otherwise only the single certificate is imported. You should be able to convert certificates to PKCS#7 format with openssl, via openssl crl2pkcs7 command.

Change the rule on your <a>
element from:
.navigation ul a {

to
.navigation ul a {
color: #000;
display: block;
padding: 0 65px 0 0;
text-decoration: none;
width:100%;
text-align:center;
}?
Just add two new rules (width:100%;
and text-align:center;
). You need to make the anchor expand to take up the full width of the list item and then text-align center it.

I've tried the other answers listed above, but they are very far from decent solutions when dealing with large files -- especially once a single line's size occupies more than ~1/4 of available RAM.
Both bash and awk slurp the entire line, even though for this problem it's not needed. Bash will error out once a line is too long, even if you have enough memory.
I've implemented an extremely simple, fairly unoptimized python script that when tested with large files (~4 GB per line) doesn't slurp, and is by far a better solution than those given.
If this is time critical code for production, you can rewrite the ideas in C or perform better optimizations on the read call (instead of only reading a single byte at a time), after testing that this is indeed a bottleneck.
Code assumes newline is a linefeed character, which is a good assumption for Unix, but YMMV on Mac OS/Windows. Be sure the file ends with a linefeed to ensure the last line character count isn't overlooked.
from sys import stdin, exit
counter = 0
while True:
byte = stdin.buffer.read(1)
counter += 1
if not byte:
exit()
if byte == b'\x0a':
print(counter-1)
counter = 0

Use the below code for a setup session cookie, it will work until browser close. (make sure not close tab)
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = "expires="+ d.toUTCString();
document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}
function getCookie(cname) {
var name = cname + "=";
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for(var i = 0; i <ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return false;
}
if(getCookie("KoiMilGaya")) {
//alert('found');
// Cookie found. Display any text like repeat user. // reload, other page visit, close tab and open again..
} else {
//alert('nothing');
// Display popup or anthing here. it shows on first visit only.
// this will load again when user closer browser and open again.
setCookie('KoiMilGaya','1');
}
My solution was to make all the parents 100% and set a specific percentage for each row:
html, body,div[class^="container"] ,.column {
height: 100%;
}
.row0 {height: 10%;}
.row1 {height: 40%;}
.row2 {height: 50%;}
Now with Android Studio and Gradle, you can have multiple resource folders in your project. Allowing to organize not only your layout files but any kind of resources.
It's not exactly a sub-folder, but may separte parts of your application.
The configuration is like this:
sourceSets {
main {
res.srcDirs = ['src/main/res', 'src/main/res2']
}
}
Check the documentation.
Mostly it depends on the platform you are using .It depends from compiler to compiler.Nowadays in most of compilers int is of 4 bytes.
If you want to check what your compiler is using you can use sizeof(int)
.
main()
{
printf("%d",sizeof(int));
printf("%d",sizeof(short));
printf("%d",sizeof(long));
}
The only thing c compiler promise is that size of short must be equal or less than int and size of long must be equal or more than int.So if size of int is 4 ,then size of short may be 2 or 4 but not larger than that.Same is true for long and int. It also says that size of short and long can not be same.
The schema for passing the value in as a string. The regex will validate a string of at least one digit, possibly followed by a period and exactly two digits:
{
"type": "string",
"pattern": "^[0-9]+(\\.[0-9]{2})?$"
}
The schema below is equivalent, except that it also allows empty strings:
{
"type": "string",
"pattern": "^$|^[0-9]+(\\.[0-9]{2})?$"
}
double minutes = varTime.TotalMinutes;
int minutesRounded = (int)Math.Round(varTime.TotalMinutes);
TimeSpan.TotalMinutes: The total number of minutes represented by this instance.
Here's an example
// in the service
getVehicles(){
return Observable.interval(2200).map(i=> [{name: 'car 1'},{name: 'car 2'}])
}
// in the controller
vehicles: Observable<Array<any>>
ngOnInit() {
this.vehicles = this._vehicleService.getVehicles();
}
// in template
<div *ngFor='let vehicle of vehicles | async'>
{{vehicle.name}}
</div>
This link tells you how.
The magic is the getResourceAsStream() method :
InputStream is =
this.getClass().getClassLoader().getResourceAsStream("yourpackage/mypackage/myfile.xml")
The obvious choices for displaying the time are the AnalogClock
View and the DigitalClock
View.
For example, the following layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<AnalogClock
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<DigitalClock
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textSize="20sp"/>
</LinearLayout>
Looks like this:
The solution I found is very simple. Use Window's WMIC & Java's Runtime to locate & kill the process.
Part 1: You need to put some sort of identifier into your app's startup command line. E.g. something like:
String id = "com.domain.app";
Part 2: When you run your app, make sure to include the string. Let's say you start it from within Java, do the following:
Runtime.getRuntime().exec(
"C:\...\javaw.exe -cp ... -Dwhatever=" + id + " com.domain.app.Main"
);
Part 3: To kill the process, use Window's WMIC. Just make sure you app was started containing your id from above:
Runtime.getRuntime().exec(
"wmic process Where \"CommandLine Like '%" + id + "%'\" Call Terminate"
);
Move import sys
outside of the try
-except
block:
import sys
try:
# ...
except ImportError:
# ...
If any of the imports before the import sys
line fails, the rest of the block is not executed, and sys
is never imported. Instead, execution jumps to the exception handling block, where you then try to access a non-existing name.
sys
is a built-in module anyway, it is always present as it holds the data structures to track imports; if importing sys
fails, you have bigger problems on your hand (as that would indicate that all module importing is broken).
A secondary option would be to match and return non-digits with some expression similar to,
/\D+/g
which would likely work for that specific string in the question (1 ding ?
).
function non_digit_string(str) {_x000D_
const regex = /\D+/g;_x000D_
let m;_x000D_
_x000D_
non_digit_arr = [];_x000D_
while ((m = regex.exec(str)) !== null) {_x000D_
// This is necessary to avoid infinite loops with zero-width matches_x000D_
if (m.index === regex.lastIndex) {_x000D_
regex.lastIndex++;_x000D_
}_x000D_
_x000D_
_x000D_
m.forEach((match, groupIndex) => {_x000D_
if (match.trim() != '') {_x000D_
non_digit_arr.push(match.trim());_x000D_
}_x000D_
});_x000D_
}_x000D_
return non_digit_arr;_x000D_
}_x000D_
_x000D_
const str = `1 ding ? 124_x000D_
12 ding ?_x000D_
123 ding ? 123`;_x000D_
console.log(non_digit_string(str));
_x000D_
If you wish to simplify/modify/explore the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.
