In Mongoose: from the document:
To remove a document from a subdocument array we may pass an object with a matching _id.
contact.phone.pull({ _id: itemId }) // remove
contact.phone.pull(itemId); // this also works

No, you can't edit the connection string in the designer. The connection string is not part of the EDMX file it is just referenced value from the configuration file and probably because of that it is just readonly in the properties window.
Modifying configuration file is common task because you sometimes wants to make change without rebuilding the application. That is the reason why configuration files exist.
In PostMan we have ->Pre-request Script. Paste the Below snippet.
const dateNow = new Date();
postman.setGlobalVariable("todayDate", dateNow.toLocaleDateString());
And now we are ready to use.
{
"firstName": "SANKAR",
"lastName": "B",
"email": "[email protected]",
"creationDate": "{{todayDate}}"
}
If you are using JPA Entity classes then use the below snippet
@JsonFormat(pattern="MM/dd/yyyy")
@Column(name = "creation_date")
private Date creationDate;
I created a kotlin extension based on responses in this topic and using the DateFormatSymbols answers you get a localized response.
fun Date.toCalendar(): Calendar {
val calendar = Calendar.getInstance()
calendar.time = this
return calendar
}
fun Date.getMonthName(): String {
val month = toCalendar()[Calendar.MONTH]
val dfs = DateFormatSymbols()
val months = dfs.months
return months[month]
}
Aforementioned answers are great, just putting few points I see might be helpful:
Func is built-in delegate type
Func delegate type must return a value. Use Action delegate if no return type needed.
Func delegate type can have zero to 16 input parameters.
Func delegate does not allow ref and out parameters.
Func delegate type can be used with an anonymous method or lambda expression.
Func<int, int, int> Sum = (x, y) => x + y;
The simplest solution would be open terminal
$ java -version
it shows the following
java version "1.6.0_65"
$ cd /System/Library/Frameworks/JavaVM.framework/Versions
$ ls -l
Below is the last line of output:
lrwxr-xr-x 1 root wheel 59 Feb 12 14:57 CurrentJDK -> /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents
1.6.0.jdk would be the answer
Addition to @jwize's answer
Because angular.element(document).injector()
was giving error injector is not defined
So, I have created function that you can run after AJAX call or when DOM is changed using jQuery.
function compileAngularElement( elSelector) {
var elSelector = (typeof elSelector == 'string') ? elSelector : null ;
// The new element to be added
if (elSelector != null ) {
var $div = $( elSelector );
// The parent of the new element
var $target = $("[ng-app]");
angular.element($target).injector().invoke(['$compile', function ($compile) {
var $scope = angular.element($target).scope();
$compile($div)($scope);
// Finally, refresh the watch expressions in the new element
$scope.$apply();
}]);
}
}
use it by passing just new element's selector. like this
compileAngularElement( '.user' ) ;
its because you probaly installed wamp server and uninstall it but wampmysql.exe still running and using the default mysql port go to msconfig under services tab uncheck wampmysqld to deactivate it reboot the computer should work
Currently your application support 100 connections in pool. Here is what conn string will look like if you want to increase it to 200:
public static string srConnectionString =
"server=localhost;database=mydb;uid=sa;pwd=mypw;Max Pool Size=200;";
You can investigate how many connections with database your application use, by executing sp_who
procedure in your database. In most cases default connection pool size will be enough.
Generate a github oauth token here and export your github token as an environment variable:
export GITHUB_TOKEN=123
Set git config to use the basic auth url:
git config --global url."https://$GITHUB_TOKEN:[email protected]/".insteadOf "https://github.com/"
Now you can go get

Instead of a RegEx
use Replace
for something that simple:
LastName = LastName.Replace(" ", String.Empty);
change:
$("input:text").change(function() {
var value=$("input:text").val();
alert(value);
});
to
$("input:text").change(function() {
var value=$("input[type=text].selector").val();
alert(value);
});
note: selector:id,class..
If you are using .NET 3.5 or newer you can use LINQ extension methods to achieve a "contains" check with the Any
extension method:
if(CartProducts.Any(prod => prod.ID == p.ID))
This will check for the existence of a product within CartProducts
which has an ID matching the ID of p
. You can put any boolean expression after the =>
to perform the check on.
This also has the benefit of working for LINQ-to-SQL queries as well as in-memory queries, where Contains
doesn't.

This is by far the best post for exporting to excel from SQL:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=49926
To quote from user madhivanan
,
Apart from using DTS and Export wizard, we can also use this query to export data from SQL Server2000 to Excel
Create an Excel file named testing having the headers same as that of table columns and use these queries
1 Export data to existing EXCEL file from SQL Server table
insert into OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:\testing.xls;',
'SELECT * FROM [SheetName$]') select * from SQLServerTable
2 Export data from Excel to new SQL Server table
select *
into SQLServerTable FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:\testing.xls;HDR=YES',
'SELECT * FROM [Sheet1$]')
3 Export data from Excel to existing SQL Server table (edited)
Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:\testing.xls;HDR=YES',
'SELECT * FROM [SheetName$]')
4 If you dont want to create an EXCEL file in advance and want to export data to it, use
EXEC sp_makewebtask
@outputfile = 'd:\testing.xls',
@query = 'Select * from Database_name..SQLServerTable',
@colheaders =1,
@FixedFont=0,@lastupdated=0,@resultstitle='Testing details'
(Now you can find the file with data in tabular format)
5 To export data to new EXCEL file with heading(column names), create the following procedure
create procedure proc_generate_excel_with_columns
(
@db_name varchar(100),
@table_name varchar(100),
@file_name varchar(100)
)
as
--Generate column names as a recordset
declare @columns varchar(8000), @sql varchar(8000), @data_file varchar(100)
select
@columns=coalesce(@columns+',','')+column_name+' as '+column_name
from
information_schema.columns
where
table_name=@table_name
select @columns=''''''+replace(replace(@columns,' as ',''''' as '),',',',''''')
--Create a dummy file to have actual data
select @data_file=substring(@file_name,1,len(@file_name)-charindex('\',reverse(@file_name)))+'\data_file.xls'
--Generate column names in the passed EXCEL file
set @sql='exec master..xp_cmdshell ''bcp " select * from (select '+@columns+') as t" queryout "'+@file_name+'" -c'''
exec(@sql)
--Generate data in the dummy file
set @sql='exec master..xp_cmdshell ''bcp "select * from '+@db_name+'..'+@table_name+'" queryout "'+@data_file+'" -c'''
exec(@sql)
--Copy dummy file to passed EXCEL file
set @sql= 'exec master..xp_cmdshell ''type '+@data_file+' >> "'+@file_name+'"'''
exec(@sql)
--Delete dummy file
set @sql= 'exec master..xp_cmdshell ''del '+@data_file+''''
exec(@sql)
After creating the procedure, execute it by supplying database name, table name and file path:
EXEC proc_generate_excel_with_columns 'your dbname', 'your table name','your file path'
Its a whomping 29 pages but that is because others show various other ways as well as people asking questions just like this one on how to do it.
Follow that thread entirely and look at the various questions people have asked and how they are solved. I picked up quite a bit of knowledge just skimming it and have used portions of it to get expected results.
To update single cells
A member also there Peter Larson posts the following: I think one thing is missing here. It is great to be able to Export and Import to Excel files, but how about updating single cells? Or a range of cells?
This is the principle of how you do manage that
update OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=c:\test.xls;hdr=no',
'SELECT * FROM [Sheet1$b7:b7]') set f1 = -99
You can also add formulas to Excel using this:
update OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=c:\test.xls;hdr=no',
'SELECT * FROM [Sheet1$b7:b7]') set f1 = '=a7+c7'
Exporting with column names using T-SQL
Member Mladen Prajdic also has a blog entry on how to do this here
References: www.sqlteam.com (btw this is an excellent blog / forum for anyone looking to get more out of SQL Server). For error referencing I used this
If you get the following error:
OLE DB provider 'Microsoft.Jet.OLEDB.4.0' cannot be used for distributed queries
Then run this:
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;
GO
The best way to deal with this (if a declaration file is not available on DefinitelyTyped) is to write declarations only for the things you use rather than the entire library. This reduces the work a lot - and additionally the compiler is there to help out by complaining about missing methods.
Put this two lines in style.css
In your specified div
class.
display: block;
margin: auto;
and then try to run it, you will be able to see that .svg aligned in the center.
This is how I've done it using parameterized commands.
MSSQL
INSERT INTO MyTable (Field1, Field2) VALUES (@Value1, @Value2);
SELECT SCOPE_IDENTITY();
MySQL
INSERT INTO MyTable (Field1, Field2) VALUES (?Value1, ?Value2);
SELECT LAST_INSERT_ID();
To simplify Amiram Korach's solution:
dtList.RemoveAll(s => string.IsNullOrWhiteSpace(s))
No need to use Distinct() or ToList()
To access a specific option you need to provide the nth-child() selector:
ptor.findElement(protractor.By.css('select option:nth-child(1)')).click();
You can use Distinct extension method from LINQ
I guess you need something like this:
const MySelect = props => (
<Select
{...props}
value={props.options.filter(option => option.label === 'Some label')}
onChange={value => props.input.onChange(value)}
onBlur={() => props.input.onBlur(props.input.value)}
options={props.options}
placeholder={props.placeholder}
/>
);
Unless I am misunderstanding the question, I would almost always use $this->get_species because the subclass (in this case dog) could overwrite that method since it does extend it. If the class dog doesn't redefine the method then both ways are functionally equivalent but if at some point in the future you decide you want the get_species method in dog should print "dog" then you would have to go back through all the code and change it.
When you use $this it is actually part of the object which you created and so will always be the most up-to-date as well (if the property being used has changed somehow in the lifetime of the object) whereas using the parent class is calling the static class method.
First google search yielded me this answer. So I thought of updating this with newer version of attach, detach.
Create database dbname
On
(
Filename= 'path where you copied files',
Filename ='path where you copied log'
)
For attach;
Further,if your database is cleanly shutdown(there are no active transactions while database was shutdown) and you dont have log file,you can use below method,SQL server will create a new transaction log file..
Create database dbname
On
(
Filename= 'path where you copied files'
)
For attach;
if you don't specify transaction log file,SQL will try to look in the default path and will try to use it irrespective of whether database was cleanly shutdown or not..
Here is what MSDN has to say about this..
If a read-write database has a single log file and you do not specify a new location for the log file, the attach operation looks in the old location for the file. If it is found, the old log file is used, regardless of whether the database was shut down cleanly. However, if the old log file is not found and if the database was shut down cleanly and has no active log chain, the attach operation attempts to build a new log file for the database.
There are some restrictions with this approach and some side affects too..
1.attach-and-detach operations both disable cross-database ownership chaining for the database
2.Database trustworthy is set to off
3.Detaching a read-only database loses information about the differential bases of differential backups.
Most importantly..you can't attach a database with recent versions to an earlier version

In case anyone is trying to apply the above solutions to a .scatter() instead of a .subplot(),
I tried running the following code
y = [2.56422, 3.77284, 3.52623, 3.51468, 3.02199]
z = [0.15, 0.3, 0.45, 0.6, 0.75]
n = [58, 651, 393, 203, 123]
fig, ax = plt.scatter(z, y)
for i, txt in enumerate(n):
ax.annotate(txt, (z[i], y[i]))
But ran into errors stating "cannot unpack non-iterable PathCollection object", with the error specifically pointing at codeline fig, ax = plt.scatter(z, y)
I eventually solved the error using the following code
plt.scatter(z, y)
for i, txt in enumerate(n):
plt.annotate(txt, (z[i], y[i]))
I didn't expect there to be a difference between .scatter() and .subplot() I should have known better.

If your page is deeply pathed or might move around and your JS script is at "~/JS/Registration.js" of your web folder, you can try the following:
<script src='<%=ResolveClientUrl("~/JS/Registration.js") %>'
type="text/javascript"></script>
Perhaps $('#fruit').val();
is not returning an array and you need something like:
$("#fruit").val() || []
curl's --data
will by default send Content-Type: application/x-www-form-urlencoded
in the request header. However, when using Postman's raw
body mode, Postman sends Content-Type: text/plain
in the request header.
So to achieve the same thing as Postman, specify -H "Content-Type: text/plain"
for curl:
curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/
Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network

One could use the Buffer
s that are provided as part of the java.nio
package to perform the conversion.
Here, the source byte[]
array has a of length 8, which is the size that corresponds with a long
value.
First, the byte[]
array is wrapped in a ByteBuffer
, and then the ByteBuffer.getLong
method is called to obtain the long
value:
ByteBuffer bb = ByteBuffer.wrap(new byte[] {0, 0, 0, 0, 0, 0, 0, 4});
long l = bb.getLong();
System.out.println(l);
Result
4
I'd like to thank dfa for pointing out the ByteBuffer.getLong
method in the comments.
Although it may not be applicable in this situation, the beauty of the Buffer
s come with looking at an array with multiple values.
For example, if we had a 8 byte array, and we wanted to view it as two int
values, we could wrap the byte[]
array in an ByteBuffer
, which is viewed as a IntBuffer
and obtain the values by IntBuffer.get
:
ByteBuffer bb = ByteBuffer.wrap(new byte[] {0, 0, 0, 1, 0, 0, 0, 4});
IntBuffer ib = bb.asIntBuffer();
int i0 = ib.get(0);
int i1 = ib.get(1);
System.out.println(i0);
System.out.println(i1);
Result:
1

Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping settings icon then scroll down to developer options and tap it then you will see on the top right a on off switch select on and then tap ok, thats it you all done.
jQuery uses a .call(...)
method to assign the current node to this
inside the function you pass as the parameter.
EDIT:
Don't be afraid to look inside jQuery's code when you have a doubt, it's all in clear and well documented Javascript.
ie: the answer to this question is around line 574,
callback.call( object[ name ], name, object[ name ] ) === false
I have been reading about Android Service very recently and got a chance to deep dive on it. I have encountered a service leak, for my situation it happened because I had an unbound Service which was starting a bound Service, but in this my unbound Service is replaced by an Activity.
So when I was stopping my unbound Service by using stopSelf() the leak occurred, the reason was I was stopping the parent service without unbinding the bound service. Now the bound service is running and it doesn't know to whom does it belong.
The easy and straight forward fix is you should call unbindService(YOUR_SERVICE); in your onDestroy() function of your parent Activity/Service. This way the lifecycle will ensure that your bound services are stopped or cleaned up before your parent Activity/Services go down.
There is one other variation of this problem. Sometimes in your bound service you want certain functions to work only if the service is bound so we end up putting a bound flag in the onServiceConnected like:
public void onServiceConnected(ComponentName name, IBinder service) {
bounded = true;
// code here
}
This works fine till here but the problem comes when we treat onServiceDisconnected function as a callback for unbindService function call, this by documentation is only called when a service is killed or crashed. And you will never get this callback in the same thread. Hence, we end up doing something like:
public void onServiceDisconnected(ComponentName name) {
bounded = false;
}
Which creates major bug in the code because our bound flag never gets reset to false and when this service is connected back again most of the times it is true
. So in order to avoid this scenario you should set the bound
to false the moment you are calling unbindService
.
This is cover in more detail in Erik's blog.
Hope who ever came here got his curiosity satisfied.
Interestingly no one answered this. In TigerVNC, when you are logged into the session. Go to System > Preference > Display
from the top menu bar ( I was using Cent OS as my remote Server). Click on the resolution drop down, there are various settings available including 1080p. Select the one that you like. It will change on the fly.
Make sure you Apply the new setting when a dialog is prompted. Otherwise it will revert back to the previous setting just like in Windows
update 2 ::slotted
::slotted
is now supported by all new browsers and can be used with ViewEncapsulation.ShadowDom
https://developer.mozilla.org/en-US/docs/Web/CSS/::slotted
update 1 ::ng-deep
/deep/
was deprecated and replaced by ::ng-deep
.
::ng-deep
is also already marked deprecated, but there is no replacement available yet.
When ViewEncapsulation.Native
is properly supported by all browsers and supports styling accross shadow DOM boundaries, ::ng-deep
will probably be discontinued.
original
Angular adds all kinds of CSS classes to the HTML it adds to the DOM to emulate shadow DOM CSS encapsulation to prevent styles of bleeding in and out of components. Angular also rewrites the CSS you add to match these added classes. For HTML added using [innerHTML]
these classes are not added and the rewritten CSS doesn't match.
As a workaround try
/* :host /deep/ mySelector { */
:host ::ng-deep mySelector {
background-color: blue;
}
index.html
/* body /deep/ mySelector { */
body ::ng-deep mySelector {
background-color: green;
}
>>>
(and the equivalent/deep/
but /deep/
works better with SASS) and ::shadow
were added in 2.0.0-beta.10. They are similar to the shadow DOM CSS combinators (which are deprecated) and only work with encapsulation: ViewEncapsulation.Emulated
which is the default in Angular2. They probably also work with ViewEncapsulation.None
but are then only ignored because they are not necessary.
These combinators are only an intermediate solution until more advanced features for cross-component styling is supported.
Another approach is to use
@Component({
...
encapsulation: ViewEncapsulation.None,
})
for all components that block your CSS (depends on where you add the CSS and where the HTML is that you want to style - might be all components in your application)
Update
I believe that the correct answer would be to make the two numbers (BigDecimals), have the same scale, then we can decide about their equality. For example, are these two numbers equal?
1.00001 and 1.00002
Well, it depends on the scale. On the scale 5 (5 decimal points), no they are not the same. but on smaller decimal precisions (scale 4 and lower) they are considered equal. So I suggest make the scale of the two numbers equal and then compare them.
I solved my problem with code below.

You may want to look into os dependent line separators, e.g.:

f1.write(content + os.linesep)
It got simplified with newer version of rxjs .
import {map} from 'rxjs/operators';
import {Observable,of, from } from 'rxjs';
Instead of chaining we need to pipe . For example
Old syntax :
source.map().switchMap().subscribe()
New Syntax:
source.pipe(map(), switchMap()).subscribe()
Note: Some operators have a name change due to name collisions with JavaScript reserved words! These include:
do
-> tap
,
catch
-> catchError
switch
-> switchAll
finally
-> finalize
I am writing this answer partly to help myself as I keep checking docs everytime I need to import an operator . Let me know if something can be done better way.
import { Rx } from 'rxjs/Rx'
;This imports the entire library. Then you don't need to worry about loading each operator . But you need to append Rx. I hope tree-shaking will optimize and pick only needed funcionts( need to verify ) As mentioned in comments , tree-shaking can not help. So this is not optimized way.
public cache = new Rx.BehaviorSubject('');
Or you can import individual operators .
This will Optimize your app to use only those files :
import { _______ } from 'rxjs/_________';
This syntax usually used for main Object like Rx
itself or Observable
etc.,
Keywords which can be imported with this syntax
Observable, Observer, BehaviorSubject, Subject, ReplaySubject
import 'rxjs/add/observable/__________';
Update for Angular 5
With Angular 5, which uses rxjs 5.5.2+
import { empty } from 'rxjs/observable/empty';
import { concat} from 'rxjs/observable/concat';
These are usually accompanied with Observable directly. For example
Observable.from()
Observable.of()
Other such keywords which can be imported using this syntax:
concat, defer, empty, forkJoin, from, fromPromise, if, interval, merge, of,
range, throw, timer, using, zip
import 'rxjs/add/operator/_________';
Update for Angular 5
With Angular 5, which uses rxjs 5.5.2+
import { filter } from 'rxjs/operators/filter';
import { map } from 'rxjs/operators/map';
These usually come in the stream after the Observable is created. Like flatMap
in this code snippet:
Observable.of([1,2,3,4])
.flatMap(arr => Observable.from(arr));
Other such keywords using this syntax:
audit, buffer, catch, combineAll, combineLatest, concat, count, debounce, delay,
distinct, do, every, expand, filter, finally, find , first, groupBy,
ignoreElements, isEmpty, last, let, map, max, merge, mergeMap, min, pluck,
publish, race, reduce, repeat, scan, skip, startWith, switch, switchMap, take,
takeUntil, throttle, timeout, toArray, toPromise, withLatestFrom, zip
FlatMap:
flatMap
is alias to mergeMap
so we need to import mergeMap
to use flatMap
.
Note for /add
imports :
We only need to import once in whole project. So its advised to do it at a single place. If they are included in multiple files, and one of them is deleted, the build will fail for wrong reasons.
There are many ways can do that!
jQuery
remove all class
$("element").removeClass();
OR
$("#item").removeAttr('class');
OR
$("#item").attr('class', '');
OR
$('#item')[0].className = '';
remove multi class
$("element").removeClass("class1 ... classn");
OR
$("element").removeClass("class1").removeClass("...").removeClass("classn");
// remove all items all class _x000D_
const items = document.querySelectorAll('item');_x000D_
for (let i = 0; i < items.length; i++) {_x000D_
items[i].className = '';_x000D_
}
_x000D_
// only remove all class of first item_x000D_
const item1 = document.querySelector('item');_x000D_
item1.className = '';
_x000D_
Go to the folder where eclipse is installed

You can convert varchars to floats, and you can do it in the manner you have expressed. Your varchar must not be a numeric value. There must be something else in it. You can use IsNumeric to test it. See this:
declare @thing varchar(100)
select @thing = '122.332'
--This returns 1 since it is numeric.
select isnumeric(@thing)
--This converts just fine.
select convert(float,@thing)
select @thing = '122.332.'
--This returns 0 since it is not numeric.
select isnumeric(@thing)
--This convert throws.
select convert(float,@thing)
The IIS inbound rules as shown in the question DO work. I had to clear the browser cache and add the following line in the top of my <head>
section of the index.html page:
<base href="/myApplication/app/" />
This is because I have more than one application in localhost and so requests to other partials were being taken to localhost/app/view1
instead of localhost/myApplication/app/view1
Hopefully this helps someone!
If there is a possibility that the element does not exist in the XML I would test both that the element is present and that the string-length is greater than zero:
<xsl:choose>
<xsl:when test="categoryName and string-length(categoryName) > 0">
<xsl:value-of select="categoryName " />
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="other" />
</xsl:otherwise>
</xsl:choose>
Correct way described in this answer: https://stackoverflow.com/a/52772444/2519714 Most popular answer at current moment is not totally correct.
This way https://stackoverflow.com/a/24838367/2519714 is not correct in some cases like: sub select has where bindings, then joining table to sub select, then other wheres added to all query. For example query:
select * from (select * from t1 where col1 = ?) join t2 on col1 = col2 and col3 = ? where t2.col4 = ?
To make this query you will write code like:
$subQuery = DB::query()->from('t1')->where('t1.col1', 'val1');
$query = DB::query()->from(DB::raw('('. $subQuery->toSql() . ') AS subquery'))
->mergeBindings($subQuery->getBindings());
$query->join('t2', function(JoinClause $join) {
$join->on('subquery.col1', 't2.col2');
$join->where('t2.col3', 'val3');
})->where('t2.col4', 'val4');
During executing this query, his method $query->getBindings()
will return bindings in incorrect order like ['val3', 'val1', 'val4']
in this case instead correct ['val1', 'val3', 'val4']
for raw sql described above.
One more time correct way to do this:
$subQuery = DB::query()->from('t1')->where('t1.col1', 'val1');
$query = DB::query()->fromSub($subQuery, 'subquery');
$query->join('t2', function(JoinClause $join) {
$join->on('subquery.col1', 't2.col2');
$join->where('t2.col3', 'val3');
})->where('t2.col4', 'val4');
Also bindings will be automatically and correctly merged to new query.

its because gallery correct displaying rotated images but not ImageView look at here:
myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath(),optionss);
ExifInterface exif = new ExifInterface(selectedImagePath);
int rotation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
int rotationInDegrees = exifToDegrees(rotation);
deg = rotationInDegrees;
Matrix matrix = new Matrix();
if (rotation != 0f) {
matrix.preRotate(rotationInDegrees);
myBitmap = Bitmap.createBitmap(myBitmap, 0, 0, myBitmap.getWidth(), myBitmap.getHeight(), matrix, true);
}
and you need this:
private static int exifToDegrees(int exifOrientation) {
if (exifOrientation == ExifInterface.ORIENTATION_ROTATE_90) { return 90; }
else if (exifOrientation == ExifInterface.ORIENTATION_ROTATE_180) { return 180; }
else if (exifOrientation == ExifInterface.ORIENTATION_ROTATE_270) { return 270; }
return 0;
}
It's pretty straightforward with some simple rules:
then
, return it - any promise you don't return will not be waited for outside..all
them - that way it waits for all the promises and no error from any of them are silenced.then
s, you can typically return in the middle - then
chains are usually at most 1 level deep.And some tips:
.map
than with for/push
- if you're mapping values with a function, map
lets you concisely express the notion of applying actions one by one and aggregating the results.Promise.all
than to execute things one after the other - each waiting before the next.Ok, so let's get started:
var items = [1, 2, 3, 4, 5];
var fn = function asyncMultiplyBy2(v){ // sample async action
return new Promise(resolve => setTimeout(() => resolve(v * 2), 100));
};
// map over forEach since it returns
var actions = items.map(fn); // run the function over all items
// we now have a promises array and we want to wait for it
var results = Promise.all(actions); // pass array of promises
results.then(data => // or just .then(console.log)
console.log(data) // [2, 4, 6, 8, 10]
);
// we can nest this of course, as I said, `then` chains:
var res2 = Promise.all([1, 2, 3, 4, 5].map(fn)).then(
data => Promise.all(data.map(fn))
).then(function(data){
// the next `then` is executed after the promise has returned from the previous
// `then` fulfilled, in this case it's an aggregate promise because of
// the `.all`
return Promise.all(data.map(fn));
}).then(function(data){
// just for good measure
return Promise.all(data.map(fn));
});
// now to get the results:
res2.then(function(data){
console.log(data); // [16, 32, 48, 64, 80]
});
I've compared performance (space and time) for a number of ways to store numpy arrays. Few of them support multiple arrays per file, but perhaps it's useful anyway.
Npy and binary files are both really fast and small for dense data. If the data is sparse or very structured, you might want to use npz with compression, which'll save a lot of space but cost some load time.
If portability is an issue, binary is better than npy. If human readability is important, then you'll have to sacrifice a lot of performance, but it can be achieved fairly well using csv (which is also very portable of course).
More details and the code are available at the github repo.

The main differnece is when you say ClassName obj = null; you are just creating an object for that class. It's not an instance of that class.
This statement will just allot memory for the static meber variables, not for the normal member variables.
But when you say ClassName obj = new ClassName(); you are creating an instance of the class. This staement will allot memory all member variables.
For me the issue had to do with the parameters assigned to the package.
In SSMS, Navigate to:
"Integration Services Catalog -> SSISDB -> Project Folder Name -> Projects -> Project Name"
Make sure you right click on your "Project Name" and then validate that 32-bit runtime is set correctly and that the parameters that are used by default are instantiated properly. Check parameter NAMES and initial values. For my package, I was using values that were not correct and so I had to repopulate the parameter defaults prior to executing my package. Check the values you are using against the defaults you have set for your parameters you have set up in your SSIS package. Once these match the issue should be resolved (for some)
Try this expression...
string-join(//element3/(concat(element4/text(), '.', element5/text())), " ")
This should do it:
SELECT *
FROM INFORMATION_SCHEMA.VIEWS
WHERE VIEW_DEFINITION like '%YourTableName%'
If you want to find all commits where commit message contains given word, use
$ git log --grep=word
If you want to find all commits where "word" was added or removed in the file contents (to be more exact: where number of occurences of "word" changed), i.e. search the commit contents, use so called 'pickaxe' search with
$ git log -Sword
In modern git there is also
$ git log -Gword
to look for differences whose added or removed line matches "word" (also commit contents).
Note that -G
by default accepts a regex, while -S
accepts a string, but can be modified to accept regexes using the --pickaxe-regex
.
To illustrate the difference between
-S<regex> --pickaxe-regex
and-G<regex>
, consider a commit with the following diff in the same file:+ return !regexec(regexp, two->ptr, 1, ®match, 0); ... - hit = !regexec(regexp, mf2.ptr, 1, ®match, 0);
While
git log -G"regexec\(regexp"
will show this commit,git log -S"regexec\(regexp" --pickaxe-regex
will not (because the number of occurrences of that string did not change).
With Git 2.25.1 (Feb. 2020), the documentation is clarified around those regexes.
See commit 9299f84 (06 Feb 2020) by Martin Ågren (``).

The lstrip()
method will remove leading whitespaces, newline and tab characters on a string beginning:
>>> ' hello world!'.lstrip()
'hello world!'
Edit
As balpha pointed out in the comments, in order to remove only spaces from the beginning of the string, lstrip(' ')
should be used:
>>> ' hello world with 2 spaces and a tab!'.lstrip(' ')
'\thello world with 2 spaces and a tab!'

I wasn't happy with any of the suggested time pickers, so I created my own with inspiration from Perifer's and the HTML5 spec:
http://github.com/gregersrygg/jquery.timeInput
You can either use the new html5 attributes for time input (step, min, max), or use an options object:
<input type="time" name="myTime" class="time-mm-hh" min="9:00" max="18:00" step="1800" />
<input type="time" name="myTime2" class="time-mm-hh" />
<script type="text/javascript">
$("input[name='myTime']").timeInput(); // use default or html5 attributes
$("input[name='myTime2']").timeInput({min: "6:00", max: "15:00", step: 900}); // 15 min intervals from 6:00 am to 3:00 pm
</script>
Validates input like this:
The HTML5 spec doesn't allow am/pm or localized time syntax, so it only allowes the format hh:mm. Seconds is allowed according to spec, but I have not implemented it yet.
It's very "alpha", so there might be some bugs. Feel free to send me patches/pull requests. Have manually tested in IE 6&8, FF, Chrome and Opera (Latest stable on Linux for the latter ones).
rand() returns the next (pseudo) random number in a series. What's happening is you have the same series each time its run (default '1'). To seed a new series, you have to call srand() before you start calling rand().
If you want something random every time, you might try:
srand (time (0));
Use delegate
and event.target
. delegate
takes advantage of the event bubbling by letting one element listen for, and handle, events on child elements. target
is the jQ-normalized property of the event
object representing the object from which the event originated.
$(document).delegate('*', 'click', function (event) {
// event.target is the element
// $(event.target).text() gets its text
});
Method 1, set it in IB:
Method 2, one line of code:
navigationController?.navigationBar.barTintColor = UIColor.blackColor()
Not an equivalent, but you can use a Scanner and a pattern to parse lines with three non-negative numbers separated by spaces, for example:
71 5796 2489
88 1136 5298
42 420 842
Here's the code using findAll
:
new Scanner(System.in).findAll("(\\d+) (\\d+) (\\d+)")
.forEach(result -> {
int fst = Integer.parseInt(result.group(1));
int snd = Integer.parseInt(result.group(2));
int third = Integer.parseInt(result.group(3));
int sum = fst + snd + third;
System.out.printf("%d + %d + %d = %d", fst, snd, third, sum);
});
Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.
So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.
Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.
Yes, it works when with the command npm install --no-optional
Using environment:
As a general way to handle error in a loop like your sample code, I would rather use:
on error resume next
for each...
'do something that might raise an error, then
if err.number <> 0 then
...
end if
next ....
If you have Pillow
installed with scipy
and it is still giving you error then check your scipy
version because it has been removed from scipy since 1.3.0rc1
.
rather install scipy 1.1.0
by :
pip install scipy==1.1.0
check https://github.com/scipy/scipy/issues/6212
The method imread
in scipy.misc
requires the forked package of PIL
named Pillow
. If you are having problem installing the right version of PIL try using imread
in other packages:
from matplotlib.pyplot import imread
im = imread(image.png)
To read jpg
images without PIL
use:
import cv2 as cv
im = cv.imread(image.jpg)
You can try
from scipy.misc.pilutil import imread
instead of from scipy.misc import imread

I suspect wpis.entry.lastChangeDate
has been somehow transformed into a string in the view, before arriving to the template.
In order to verify this hypothesis, you may just check in the view if it has some property/method that only strings have - like for instance wpis.entry.lastChangeDate.upper
, and then see if the template crashes.
You could also create your own custom filter, and use it for debugging purposes, letting it inspect the object, and writing the results of the inspection on the page, or simply on the console. It would be able to inspect the object, and check if it is really a DateTimeField.
On an unrelated notice, why don't you use models.DateTimeField(
auto_now_add
=True)
to set the datetime on creation?

On modern browsers (FF >= 3.6, Chrome >= 19.0, Opera >= 12.0, and buggy on Safari), you can use the HTML5 File API. When the value of a file input changes, this API will allow you to check whether the file size is within your requirements. Of course, this, as well as MAX_FILE_SIZE
, can be tampered with so always use server side validation.
<form method="post" enctype="multipart/form-data" action="upload.php">
<input type="file" name="file" id="file" />
<input type="submit" name="submit" value="Submit" />
</form>
<script>
document.forms[0].addEventListener('submit', function( evt ) {
var file = document.getElementById('file').files[0];
if(file && file.size < 10485760) { // 10 MB (this size is in bytes)
//Submit form
} else {
//Prevent default and display error
evt.preventDefault();
}
}, false);
</script>
On the server side, it is impossible to stop an upload from happening from PHP because once PHP has been invoked the upload has already completed. If you are trying to save bandwidth, you can deny uploads from the server side with the ini setting upload_max_filesize
. The trouble with this is this applies to all uploads so you'll have to pick something liberal that works for all of your uploads. The use of MAX_FILE_SIZE
has been discussed in other answers. I suggest reading the manual on it. Do know that it, along with anything else client side (including the javascript check), can be tampered with so you should always have server side (PHP) validation.
On the server side you should validate that the file is within the size restrictions (because everything up to this point except for the INI setting could be tampered with). You can use the $_FILES
array to find out the upload size. (Docs on the contents of $_FILES
can be found below the MAX_FILE_SIZE
docs)
upload.php
<?php
if(isset($_FILES['file'])) {
if($_FILES['file']['size'] > 10485760) { //10 MB (size is also in bytes)
// File too big
} else {
// File within size restrictions
}
}
Another fast solution that saves boilerplate code is Lombok EqualsAndHashCode annotation. It is easy, elegant and customizable. And does not depends on the IDE. For example;
import lombok.EqualsAndHashCode;
@EqualsAndHashCode(of={"errorNumber","messageCode"}) // Will only use this fields to generate equals.
public class ErrorMessage{
private long errorNumber;
private int numberOfParameters;
private Level loggingLevel;
private String messageCode;
See the options avaliable to customize which fields to use in the equals. Lombok is avalaible in maven. Just add it with provided scope:
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.14.8</version>
<scope>provided</scope>
</dependency>
The clue is to work with the dict's items (i.e. key-value pair tuples). Then by using the second element of the item as the max
key (as opposed to the dict
key) you can easily extract the highest value and its associated key.
mydict = {'A':4,'B':10,'C':0,'D':87}
>>> max(mydict.items(), key=lambda k: k[1])
('D', 87)
>>> min(mydict.items(), key=lambda k: k[1])
('C', 0)
The value you are setting in the timeout
attribute is the one of the correct ways to set the session timeout value.
The timeout
attribute specifies the number of minutes a session can be idle before it is abandoned. The default value for this attribute is 20.
By assigning a value of 1 to this attribute, you've set the session to be abandoned in 1 minute after its idle.
To test this, create a simple aspx page, and write this code in the Page_Load event,
Response.Write(Session.SessionID);
Open a browser and go to this page. A session id will be printed. Wait for a minute to pass, then hit refresh. The session id will change.
Now, if my guess is correct, you want to make your users log out as soon as the session times out. For doing this, you can rig up a login page which will verify the user credentials, and create a session variable like this -
Session["UserId"] = 1;
Now, you will have to perform a check on every page for this variable like this -
if(Session["UserId"] == null)
Response.Redirect("login.aspx");
This is a bare-bones example of how this will work.
But, for making your production quality secure apps, use Roles & Membership classes provided by ASP.NET. They provide Forms-based authentication which is much more reliabletha the normal Session-based authentication you are trying to use.

One way to accomplish this is...
$('select').select2().select2('val', $('.select2 option:eq(1)').val());
So basically you first initalize the plugin then specify the default value using the 'val' parameter. The actual value is taken from the specified option, in this case #1. So the selected value from this example would be "bar".
<select class=".select2">
<option id="foo">Some Text</option>
<option id="bar">Other Text</option>
</select>

_
has 3 main conventional uses in Python:
To hold the result of the last executed expression(/statement) in an interactive interpreter session (see docs). This precedent was set by the standard CPython interpreter, and other interpreters have followed suit
For translation lookup in i18n (see the gettext documentation for example), as in code like
raise forms.ValidationError(_("Please enter a correct username"))
As a general purpose "throwaway" variable name:
To indicate that part of a function result is being deliberately ignored (Conceptually, it is being discarded.), as in code like:
label, has_label, _ = text.partition(':')
As part of a function definition (using either def
or lambda
), where
the signature is fixed (e.g. by a callback or parent class API), but
this particular function implementation doesn't need all of the
parameters, as in code like:
def callback(_):
return True
[For a long time this answer didn't list this use case, but it came up often enough, as noted here, to be worth listing explicitly.]
This use case can conflict with the translation lookup use case, so it is necessary to avoid using _
as a throwaway variable in any code block that also uses it for i18n translation (many folks prefer a double-underscore, __
, as their throwaway variable for exactly this reason).
Linters often recognize this use case. For example year, month, day = date()
will raise a lint warning if day
is not used later in the code. The fix, if day
is truly not needed, is to write year, month, _ = date()
. Same with lambda functions, lambda arg: 1.0
creates a function requiring one argument but not using it, which will be caught by lint. The fix is to write lambda _: 1.0
. An unused variable is often hiding a bug/typo (e.g. set day
but use dya
in the next line).
The compiler is telling you that there are problems starting at line 122 in the middle of that strange FBI-CIA warning message. That message is not valid C++ code and is NOT commented out so of course it will cause compiler errors. Try removing that entire message.
Also, I agree with In silico: you should always tell us what you tried and exactly what error messages you got.

Just change the Controller/Action names to your desired default. That should be the last route in the Routing Table.
dex2jar helps to decompile your apk but not 100%. You will have some problems with .smali files. Dex2jar cannot convert it to java. I know one application that can decompile your apk source files and no problems with .smali files. Here is a link http://www.hensence.com/en/smali2java/
I solved the similar problem using a simple method recently.
public static void main(String[] args) throws IOException, ParseException {
TimeZone utc = TimeZone.getTimeZone("UTC");
Calendar calendar = Calendar.getInstance(utc);
Date until = calendar.getTime();
calendar.add(Calendar.DAY_OF_MONTH, -7);
Date since = calendar.getTime();
long durationInSeconds = TimeUnit.MILLISECONDS.toSeconds(until.getTime() - since.getTime());
long SECONDS_IN_A_MINUTE = 60;
long MINUTES_IN_AN_HOUR = 60;
long HOURS_IN_A_DAY = 24;
long DAYS_IN_A_MONTH = 30;
long MONTHS_IN_A_YEAR = 12;
long sec = (durationInSeconds >= SECONDS_IN_A_MINUTE) ? durationInSeconds % SECONDS_IN_A_MINUTE : durationInSeconds;
long min = (durationInSeconds /= SECONDS_IN_A_MINUTE) >= MINUTES_IN_AN_HOUR ? durationInSeconds%MINUTES_IN_AN_HOUR : durationInSeconds;
long hrs = (durationInSeconds /= MINUTES_IN_AN_HOUR) >= HOURS_IN_A_DAY ? durationInSeconds % HOURS_IN_A_DAY : durationInSeconds;
long days = (durationInSeconds /= HOURS_IN_A_DAY) >= DAYS_IN_A_MONTH ? durationInSeconds % DAYS_IN_A_MONTH : durationInSeconds;
long months = (durationInSeconds /=DAYS_IN_A_MONTH) >= MONTHS_IN_A_YEAR ? durationInSeconds % MONTHS_IN_A_YEAR : durationInSeconds;
long years = (durationInSeconds /= MONTHS_IN_A_YEAR);
String duration = getDuration(sec,min,hrs,days,months,years);
System.out.println(duration);
}
private static String getDuration(long secs, long mins, long hrs, long days, long months, long years) {
StringBuffer sb = new StringBuffer();
String EMPTY_STRING = "";
sb.append(years > 0 ? years + (years > 1 ? " years " : " year "): EMPTY_STRING);
sb.append(months > 0 ? months + (months > 1 ? " months " : " month "): EMPTY_STRING);
sb.append(days > 0 ? days + (days > 1 ? " days " : " day "): EMPTY_STRING);
sb.append(hrs > 0 ? hrs + (hrs > 1 ? " hours " : " hour "): EMPTY_STRING);
sb.append(mins > 0 ? mins + (mins > 1 ? " mins " : " min "): EMPTY_STRING);
sb.append(secs > 0 ? secs + (secs > 1 ? " secs " : " secs "): EMPTY_STRING);
sb.append("ago");
return sb.toString();
}
And as expected it prints: 7 days ago
.
This returns the last modified date and its age.

Docker images are pretty minimal, But you can install ping
in your official ubuntu docker image via:
apt-get update
apt-get install iputils-ping
Chances are you dont need ping
your image, and just want to use it for testing purposes. Above example will help you out.
But if you need ping to exist on your image, you can create a Dockerfile
or commit
the container you ran the above commands in to a new image.
Commit:
docker commit -m "Installed iputils-ping" --author "Your Name <[email protected]>" ContainerNameOrId yourrepository/imagename:tag
Dockerfile:
FROM ubuntu
RUN apt-get update && apt-get install -y iputils-ping
CMD bash
Please note there are best practices on creating docker images, Like clearing apt cache files after and etc.
The return type must be the same as, or a subtype of, the return type declared in the original overridden method in the superclass.
This one is like the answer above which uses the MySql DATE_FORMAT() function. I also selected just one specific week in Jan.
SELECT

Don't forget to make sure that you have no special characters in your file/folder names. Happened to me with ":" when I was setting folder names using variable(s)
not allowed characters in file/folder names
" * / : < > ? \ |
U may find this code helpful in such a case.
The below code removes all ":" and replaces them with "-"
//actualFileName = "qwerty:asdfg:zxcvb" say...
String[] tempFileNames;
String tempFileName ="";
String delimiter = ":";
tempFileNames = actualFileName.split(delimiter);
tempFileName = tempFileNames[0];
for (int j = 1; j < tempFileNames.length; j++){
tempFileName = tempFileName+" - "+tempFileNames[j];
}
File file = new File(Environment.getExternalStorageDirectory(), "/MyApp/"+ tempFileName+ "/");
if (!file.exists()) {
if (!file.mkdirs()) {
Log.e("TravellerLog :: ", "Problem creating Image folder");
}
}
In my case I used blow code for different environment.

You must add setActionCommand
to the JRadioButton
then just do:
String entree = entreeGroup.getSelection().getActionCommand();
Example:
java = new JRadioButton("Java");
java.setActionCommand("Java");
c = new JRadioButton("C/C++");
c.setActionCommand("c");
System.out.println("Selected Radio Button: " +
buttonGroup.getSelection().getActionCommand());
You can always just use jQuery to add a class, .addClass
or .toggleClass
. Then you can keep all your styles in your CSS and out of your scripts.
First go to the directory where your python script is present by using-
cd path/to/directory
then simply do:

We have similar situation right now and as of this answer, I am using laravel 5.6 release.
I will not use your example in the question but mine, because it's related though.
I have route like this:
Route::name('your.name.here')->get('/your/uri', 'YourController@someMethod');
Then in your controller method, make sure you include
use Illuminate\Http\Request;
and this should be above your controller, most likely a default, if generated using php artisan
, now to get variable from the url it should look like this:
public function someMethod(Request $request)
{
$foo = $request->input("start");
$bar = $request->input("limit");
// some codes here
}
Regardless of the HTTP verb, the input() method may be used to retrieve user input.

Hope this help.
If it's a directory relative to the file that does the requiring (e.g. you want to load all files in the lib directory):
Dir[File.dirname(__FILE__) + '/lib/*.rb'].each {|file| require file }
Edit: Based on comments below, an updated version:
Dir[File.join(__dir__, 'lib', '*.rb')].each { |file| require file }
The primary difference is, @Autowired
is a spring annotation. Whereas @Resource
is specified by the JSR-250, as you pointed out yourself. So the latter is part of Java whereas the former is Spring specific.
Hence, you are right in suggesting that, in a sense. I found folks use @Autowired
with @Qualifier
because it is more powerful. Moving from some framework to some other is considered very unlikely, if not myth, especially in the case of Spring.
just implement CommandLineRunner for spring boot application. You need to implement run method,
public classs SpringBootApplication implements CommandLineRunner{
@Override
public void run(String... arg0) throws Exception {
// write your logic here
}
}
Try this:
public void double randomFill() {
Random rand = new Random();
for (int i = 0; i < this.anArray.length(); i++)
this.anArray[i] = rand.nextInt();
}
You must include jQuery in the project.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
I didn't find any doc about this so I just opened a random code example from tutorialrepublic.com http://www.tutorialrepublic.com/twitter-bootstrap-tutorial/bootstrap-dropdowns.php
Hope this helps someone else.
If you want you can throw a new Exception, with the original one set as an inner exception.
A slight deviation from the original question however may prove useful for future people landing here wanting to DROP
and CREATE
an index, i.e. in a deployment script.
You can bypass the exists check simply by adding the following to your create statement:
CREATE INDEX IX_IndexName
ON dbo.TableName
WITH (DROP_EXISTING = ON);
Read more here: CREATE INDEX (Transact-SQL) - DROP_EXISTING Clause
N.B. As mentioned in the comments, the index must already exist for this clause to work without throwing an error.

Let me refer to GNU Make manual "Setting variables" and "Flavors", and add some comments.
The value you specify is installed verbatim; if it contains references to other variables, these references are expanded whenever this variable is substituted (in the course of expanding some other string). When this happens, it is called recursive expansion.
foo = $(bar)
The catch: foo
will be expanded to the value of $(bar)
each time foo
is evaluated, possibly resulting in different values. Surely you cannot call it "lazy"! This can surprise you if executed on midnight:
# This variable is haunted!
WHEN = $(shell date -I)
something:
touch $(WHEN).flag
# If this is executed on 00:00:00:000, $(WHEN) will have a different value!
something-else-later: something
test -f $(WHEN).flag || echo "Boo!"
VARIABLE := value
VARIABLE ::= value
Variables defined with ‘:=’ or ‘::=’ are simply expanded variables.
Simply expanded variables are defined by lines using ‘:=’ or ‘::=’ [...]. Both forms are equivalent in GNU make; however only the ‘::=’ form is described by the POSIX standard [...] 2012.
The value of a simply expanded variable is scanned once and for all, expanding any references to other variables and functions, when the variable is defined.
Not much to add. It's evaluated immediately, including recursive expansion of, well, recursively expanded variables.
The catch: If VARIABLE
refers to ANOTHER_VARIABLE
:
VARIABLE := $(ANOTHER_VARIABLE)-yohoho
and ANOTHER_VARIABLE
is not defined before this assignment, ANOTHER_VARIABLE
will expand to an empty value.
FOO ?= bar
is equivalent to
ifeq ($(origin FOO), undefined)
FOO = bar
endif
where $(origin FOO)
equals to undefined
only if the variable was not set at all.
The catch: if FOO
was set to an empty string, either in makefiles, shell environment, or command line overrides, it will not be assigned bar
.
VAR += bar
When the variable in question has not been defined before, ‘+=’ acts just like normal ‘=’: it defines a recursively-expanded variable. However, when there is a previous definition, exactly what ‘+=’ does depends on what flavor of variable you defined originally.
So, this will print foo bar
:
VAR = foo
# ... a mile of code
VAR += $(BAR)
BAR = bar
$(info $(VAR))
but this will print foo
:
VAR := foo
# ... a mile of code
VAR += $(BAR)
BAR = bar
$(info $(VAR))
The catch is that +=
behaves differently depending on what type of variable VAR
was assigned before.
The syntax to assign multiline value to a variable is:
define VAR_NAME :=
line
line
endef
or
define VAR_NAME =
line
line
endef
Assignment operator can be omitted, then it creates a recursively-expanded variable.
define VAR_NAME
line
line
endef
The last newline before endef
is removed.
HASH != printf '\043'
is the same as
HASH := $(shell printf '\043')
Don't use it. $(shell)
call is more readable, and the usage of both in a makefiles is highly discouraged. At least, $(shell)
follows Joel's advice and makes wrong code look obviously wrong.

Messages have content. Content can be text, html, a DataHandler or a Multipart, and there can only be one content. Multiparts only have BodyParts but can have more than one. BodyParts, like Messages, can have content which has already been described.
A message with HTML, text and an a attachment can be viewed hierarchically like this:
message
mainMultipart (content for message, subType="mixed")
->htmlAndTextBodyPart (bodyPart1 for mainMultipart)
->htmlAndTextMultipart (content for htmlAndTextBodyPart, subType="alternative")
->textBodyPart (bodyPart2 for the htmlAndTextMultipart)
->text (content for textBodyPart)
->htmlBodyPart (bodyPart1 for htmlAndTextMultipart)
->html (content for htmlBodyPart)
->fileBodyPart1 (bodyPart2 for the mainMultipart)
->FileDataHandler (content for fileBodyPart1 )
And the code to build such a message:
// the parent or main part if you will
Multipart mainMultipart = new MimeMultipart("mixed");
// this will hold text and html and tells the client there are 2 versions of the message (html and text). presumably text
// being the alternative to html
Multipart htmlAndTextMultipart = new MimeMultipart("alternative");
// set text
MimeBodyPart textBodyPart = new MimeBodyPart();
textBodyPart.setText(text);
htmlAndTextMultipart.addBodyPart(textBodyPart);
// set html (set this last per rfc1341 which states last = best)
MimeBodyPart htmlBodyPart = new MimeBodyPart();
htmlBodyPart.setContent(html, "text/html; charset=utf-8");
htmlAndTextMultipart.addBodyPart(htmlBodyPart);
// stuff the multipart into a bodypart and add the bodyPart to the mainMultipart
MimeBodyPart htmlAndTextBodyPart = new MimeBodyPart();
htmlAndTextBodyPart.setContent(htmlAndTextMultipart);
mainMultipart.addBodyPart(htmlAndTextBodyPart);
// attach file body parts directly to the mainMultipart
MimeBodyPart filePart = new MimeBodyPart();
FileDataSource fds = new FileDataSource("/path/to/some/file.txt");
filePart.setDataHandler(new DataHandler(fds));
filePart.setFileName(fds.getName());
mainMultipart.addBodyPart(filePart);
// set message content
message.setContent(mainMultipart);
I was presented with this problem about a year ago when it came to looking up user entered information about a oil rig in a database of miscellaneous information. The goal was to do some sort of fuzzy string search that could identify the database entry with the most common elements.
Part of the research involved implementing the Levenshtein distance algorithm, which determines how many changes must be made to a string or phrase to turn it into another string or phrase.
The implementation I came up with was relatively simple, and involved a weighted comparison of the length of the two phrases, the number of changes between each phrase, and whether each word could be found in the target entry.
The article is on a private site so I'll do my best to append the relevant contents here:
Fuzzy String Matching is the process of performing a human-like estimation of the similarity of two words or phrases. In many cases, it involves identifying words or phrases which are most similar to each other. This article describes an in-house solution to the fuzzy string matching problem and its usefulness in solving a variety of problems which can allow us to automate tasks which previously required tedious user involvement.
Introduction
The need to do fuzzy string matching originally came about while developing the Gulf of Mexico Validator tool. What existed was a database of known gulf of Mexico oil rigs and platforms, and people buying insurance would give us some badly typed out information about their assets and we had to match it to the database of known platforms. When there was very little information given, the best we could do is rely on an underwriter to "recognize" the one they were referring to and call up the proper information. This is where this automated solution comes in handy.
I spent a day researching methods of fuzzy string matching, and eventually stumbled upon the very useful Levenshtein distance algorithm on Wikipedia.
Implementation
After reading about the theory behind it, I implemented and found ways to optimize it. This is how my code looks like in VBA:
'Calculate the Levenshtein Distance between two strings (the number of insertions,
'deletions, and substitutions needed to transform the first string into the second)
Public Function LevenshteinDistance(ByRef S1 As String, ByVal S2 As String) As Long
Dim L1 As Long, L2 As Long, D() As Long 'Length of input strings and distance matrix
Dim i As Long, j As Long, cost As Long 'loop counters and cost of substitution for current letter
Dim cI As Long, cD As Long, cS As Long 'cost of next Insertion, Deletion and Substitution
L1 = Len(S1): L2 = Len(S2)
ReDim D(0 To L1, 0 To L2)
For i = 0 To L1: D(i, 0) = i: Next i
For j = 0 To L2: D(0, j) = j: Next j
For j = 1 To L2
For i = 1 To L1
cost = Abs(StrComp(Mid$(S1, i, 1), Mid$(S2, j, 1), vbTextCompare))
cI = D(i - 1, j) + 1
cD = D(i, j - 1) + 1
cS = D(i - 1, j - 1) + cost
If cI <= cD Then 'Insertion or Substitution
If cI <= cS Then D(i, j) = cI Else D(i, j) = cS
Else 'Deletion or Substitution
If cD <= cS Then D(i, j) = cD Else D(i, j) = cS
End If
Next i
Next j
LevenshteinDistance = D(L1, L2)
End Function
Simple, speedy, and a very useful metric. Using this, I created two separate metrics for evaluating the similarity of two strings. One I call "valuePhrase" and one I call "valueWords". valuePhrase is just the Levenshtein distance between the two phrases, and valueWords splits the string into individual words, based on delimiters such as spaces, dashes, and anything else you'd like, and compares each word to each other word, summing up the shortest Levenshtein distance connecting any two words. Essentially, it measures whether the information in one 'phrase' is really contained in another, just as a word-wise permutation. I spent a few days as a side project coming up with the most efficient way possible of splitting a string based on delimiters.
valueWords, valuePhrase, and Split function:
Public Function valuePhrase#(ByRef S1$, ByRef S2$)
valuePhrase = LevenshteinDistance(S1, S2)
End Function
Public Function valueWords#(ByRef S1$, ByRef S2$)
Dim wordsS1$(), wordsS2$()
wordsS1 = SplitMultiDelims(S1, " _-")
wordsS2 = SplitMultiDelims(S2, " _-")
Dim word1%, word2%, thisD#, wordbest#
Dim wordsTotal#
For word1 = LBound(wordsS1) To UBound(wordsS1)
wordbest = Len(S2)
For word2 = LBound(wordsS2) To UBound(wordsS2)
thisD = LevenshteinDistance(wordsS1(word1), wordsS2(word2))
If thisD < wordbest Then wordbest = thisD
If thisD = 0 Then GoTo foundbest
Next word2
foundbest:
wordsTotal = wordsTotal + wordbest
Next word1
valueWords = wordsTotal
End Function

End Function
Measures of Similarity
Using these two metrics, and a third which simply computes the distance between two strings, I have a series of variables which I can run an optimization algorithm to achieve the greatest number of matches. Fuzzy string matching is, itself, a fuzzy science, and so by creating linearly independent metrics for measuring string similarity, and having a known set of strings we wish to match to each other, we can find the parameters that, for our specific styles of strings, give the best fuzzy match results.
Initially, the goal of the metric was to have a low search value for for an exact match, and increasing search values for increasingly permuted measures. In an impractical case, this was fairly easy to define using a set of well defined permutations, and engineering the final formula such that they had increasing search values results as desired.
In the above screenshot, I tweaked my heuristic to come up with something that I felt scaled nicely to my perceived difference between the search term and result. The heuristic I used for Value Phrase
in the above spreadsheet was =valuePhrase(A2,B2)-0.8*ABS(LEN(B2)-LEN(A2))
. I was effectively reducing the penalty of the Levenstein distance by 80% of the difference in the length of the two "phrases". This way, "phrases" that have the same length suffer the full penalty, but "phrases" which contain 'additional information' (longer) but aside from that still mostly share the same characters suffer a reduced penalty. I used the Value Words
function as is, and then my final SearchVal
heuristic was defined as =MIN(D2,E2)*0.8+MAX(D2,E2)*0.2
- a weighted average. Whichever of the two scores was lower got weighted 80%, and 20% of the higher score. This was just a heuristic that suited my use case to get a good match rate. These weights are something that one could then tweak to get the best match rate with their test data.
As you can see, the last two metrics, which are fuzzy string matching metrics, already have a natural tendency to give low scores to strings that are meant to match (down the diagonal). This is very good.
Application To allow the optimization of fuzzy matching, I weight each metric. As such, every application of fuzzy string match can weight the parameters differently. The formula that defines the final score is a simply combination of the metrics and their weights:
value = Min(phraseWeight*phraseValue, wordsWeight*wordsValue)*minWeight
+ Max(phraseWeight*phraseValue, wordsWeight*wordsValue)*maxWeight
+ lengthWeight*lengthValue
Using an optimization algorithm (neural network is best here because it is a discrete, multi-dimentional problem), the goal is now to maximize the number of matches. I created a function that detects the number of correct matches of each set to each other, as can be seen in this final screenshot. A column or row gets a point if the lowest score is assigned the the string that was meant to be matched, and partial points are given if there is a tie for the lowest score, and the correct match is among the tied matched strings. I then optimized it. You can see that a green cell is the column that best matches the current row, and a blue square around the cell is the row that best matches the current column. The score in the bottom corner is roughly the number of successful matches and this is what we tell our optimization problem to maximize.
The algorithm was a wonderful success, and the solution parameters say a lot about this type of problem. You'll notice the optimized score was 44, and the best possible score is 48. The 5 columns at the end are decoys, and do not have any match at all to the row values. The more decoys there are, the harder it will naturally be to find the best match.
In this particular matching case, the length of the strings are irrelevant, because we are expecting abbreviations that represent longer words, so the optimal weight for length is -0.3, which means we do not penalize strings which vary in length. We reduce the score in anticipation of these abbreviations, giving more room for partial word matches to supersede non-word matches that simply require less substitutions because the string is shorter.
The word weight is 1.0 while the phrase weight is only 0.5, which means that we penalize whole words missing from one string and value more the entire phrase being intact. This is useful because a lot of these strings have one word in common (the peril) where what really matters is whether or not the combination (region and peril) are maintained.
Finally, the min weight is optimized at 10 and the max weight at 1. What this means is that if the best of the two scores (value phrase and value words) isn't very good, the match is greatly penalized, but we don't greatly penalize the worst of the two scores. Essentially, this puts emphasis on requiring either the valueWord or valuePhrase to have a good score, but not both. A sort of "take what we can get" mentality.
It's really fascinating what the optimized value of these 5 weights say about the sort of fuzzy string matching taking place. For completely different practical cases of fuzzy string matching, these parameters are very different. I've used it for 3 separate applications so far.
While unused in the final optimization, a benchmarking sheet was established which matches columns to themselves for all perfect results down the diagonal, and lets the user change parameters to control the rate at which scores diverge from 0, and note innate similarities between search phrases (which could in theory be used to offset false positives in the results)
Further Applications
This solution has potential to be used anywhere where the user wishes to have a computer system identify a string in a set of strings where there is no perfect match. (Like an approximate match vlookup for strings).
So what you should take from this, is that you probably want to use a combination of high level heuristics (finding words from one phrase in the other phrase, length of both phrases, etc) along with the implementation of the Levenshtein distance algorithm. Because deciding which is the "best" match is a heuristic (fuzzy) determination - you'll have to come up with a set of weights for any metrics you come up with to determine similarity.
With the appropriate set of heuristics and weights, you'll have your comparison program quickly making the decisions that you would have made.
The user unicornaddict has a nice algorithm above, but unfortunately it contains a bug for non-loopy lists of odd length >= 3. The problem is that fast
can get "stuck" just before the end of the list, slow
catches up to it, and a loop is (wrongly) detected.
Here's the corrected algorithm.
static boolean hasLoop(Node first) {
if(first == null) // list does not exist..so no loop either.
return false;
Node slow, fast; // create two references.
slow = fast = first; // make both refer to the start of the list.
while(true) {
slow = slow.next; // 1 hop.
if(fast.next == null)
fast = null;
else
fast = fast.next.next; // 2 hops.
if(fast == null) // if fast hits null..no loop.
return false;
if(slow == fast) // if the two ever meet...we must have a loop.
return true;
}
}
Try this it will work fine.

On Linux there is also a very neat tool that can tell right away what each error code means. On Ubuntu: apt-get install errno
.
Then if for example you want to get the description of error type 2, just type errno 2
in the terminal.
With errno -l
you get a list with all errors and their descriptions. Much easier that other methods mentioned by previous posters.
When you normalize a matrix using NORM_L1, you are dividing every pixel value by the sum of absolute values of all the pixels in the image. As a result, all pixel values become much less than 1 and you get a black image. Try NORM_MINMAX instead of NORM_L1.
For that you just need write to some lines
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.setDrawerIndicatorEnabled(true);
toggle.syncState();
toggle.setDrawerIndicatorEnabled(true); if this is false make it true or remove this line

Here's another module for consideration. It seems a viable choice for more demanding applications.
Py-notify is a Python package providing tools for implementing Observer programming pattern. These tools include signals, conditions and variables.
Signals are lists of handlers that are called when signal is emitted. Conditions are basically boolean variables coupled with a signal that is emitted when condition state changes. They can be combined using standard logical operators (not, and, etc.) into compound conditions. Variables, unlike conditions, can hold any Python object, not just booleans, but they cannot be combined.
I had the same issue, I added the component in the index.ts of a=of the folder and did a export. Still the undefined error was popping. But the IDE pop our any red squiggly lines
Then as suggested changed from
import { SearchComponent } from './';
to
import { SearchComponent } from './search/search.component';
In my case, this error occured when creating a new Android Studio (Android studio 3.2.1) Java Project with
classpath 'com.android.tools.build:gradle:2.0.0-beta6'
So I´ve downgraded to
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
}
Not the best solution stay at an older version, but maybe it´s just a temporary bug in the beta as the NDK path in local.properties is still the same, but the IDE doesn´t complain anymore
In EF Core you can enter the command Remove-Migration
in the package manager console after you've added your erroneous migration.
The console suggests you do so if your migration could involve a loss of data:
An operation was scaffolded that may result in the loss of data. Please review the migration for accuracy. To undo this action, use Remove-Migration.
The best way around this would be to create an Excel called 'launcher.xlsm' in the same folder as the file you wish to open. In the 'launcher' file put the following code in the 'Workbook' object, but set the constant TargetWBName
to be the name of the file you wish to open.
Private Const TargetWBName As String = "myworkbook.xlsx"
'// First, a function to tell us if the workbook is already open...
Function WorkbookOpen(WorkBookName As String) As Boolean
' returns TRUE if the workbook is open
WorkbookOpen = False
On Error GoTo WorkBookNotOpen
If Len(Application.Workbooks(WorkBookName).Name) > 0 Then
WorkbookOpen = True
Exit Function
End If
WorkBookNotOpen:
End Function
Private Sub Workbook_Open()
'Check if our target workbook is open
If WorkbookOpen(TargetWBName) = False Then
'set calculation to manual
Application.Calculation = xlCalculationManual
Workbooks.Open ThisWorkbook.Path & "\" & TargetWBName
DoEvents
Me.Close False
End If
End Sub
Set the constant 'TargetWBName' to be the name of the workbook that you wish to open.
This code will simply switch calculation to manual, then open the file. The launcher file will then automatically close itself.
*NOTE: If you do not wish to be prompted to 'Enable Content' every time you open this file (depending on your security settings) you should temporarily remove the 'me.close' to prevent it from closing itself, save the file and set it to be trusted, and then re-enable the 'me.close' call before saving again. Alternatively, you could just set the False to True
after Me.Close
I tried the following and it didn't work on my environment:
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory", getCustomSocketFactory());
But different property worked like a charm:
bindingProvider.getRequestContext().put(JAXWSProperties.SSL_SOCKET_FACTORY, getCustomSocketFactory());
The rest of the code was taken from the first reply.
Does that work in IE6?
No, IE6 does not support attribute selectors at all, cf. CSS Compatibility and Internet Explorer.
You might find How to workaround: IE6 does not support CSS “attribute” selectors worth the read.
EDIT
If you are to ignore IE6, you could do (CSS2.1):
input[type=submit][disabled=disabled],
button[disabled=disabled] {
...
}
CSS3 (IE9+):
input[type=submit]:disabled,
button:disabled {
...
}
You can substitute [disabled=disabled]
(attribute value) with [disabled]
(attribute presence).

You need add parameter errors='coerce'
to function to_numeric
:
ID = pd.to_numeric(ID, errors='coerce')
If ID
is column:
df.ID = pd.to_numeric(df.ID, errors='coerce')
but non numeric are converted to NaN
, so all values are float
.
For int
need convert NaN
to some value e.g. 0
and then cast to int
:
df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)
Sample:
df = pd.DataFrame({'ID':['4806105017087','4806105017087','CN414149']})
print (df)
ID
0 4806105017087
1 4806105017087
2 CN414149
print (pd.to_numeric(df.ID, errors='coerce'))
0 4.806105e+12
1 4.806105e+12
2 NaN
Name: ID, dtype: float64
df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)
print (df)
ID
0 4806105017087
1 4806105017087
2 0
EDIT: If use pandas 0.25+ then is possible use integer_na
:
df.ID = pd.to_numeric(df.ID, errors='coerce').astype('Int64')
print (df)
ID
0 4806105017087
1 4806105017087
2 NaN
When creating a PWA, a service worker used on an non https server also generates this error.
I had this:
class Util {
static boolean isNeverAsync = System.getenv().get("asyncc_exclude_redundancy").equals("yes");
}
you can probably see the problem, the env var might return null instead of string. So just to test my theory, I changed it to:
class Util {
static boolean isNeverAsync = false;
}
and the problem went away. Too bad that Java can't give you the exact stack trace of the error though, kinda weird.
Was having the same error and fixing the credentials in the IIS app pool did not help. I finally resolved the error in IIS by selecting my website under Default Web Site, Advanced Settings->Physical Path Credentials->Specific User, and reentered the credentials for the app pool user, then restarted IIS and the error went away and my website came up successfully.
'a' in x

You can use this way because id can not be sequential in all cases.
SELECT *
FROM `ht_news`
LIMIT 0 , 30
You can use backticks
.
$ echo myfilename-"`date +"%d-%m-%Y"`"
Yields:

there's also an interesting tool called CUFON. There's a demonstration of how to use it in this blog It's really simple and interesting. Also, it doesn't allow people to ctrl+c/ctrl+v the generated content.
Another solution would be to use higher-order functions as follows
opt.<Runnable>map(value -> () -> System.out.println("Found " + value))
.orElse(() -> System.out.println("Not Found"))
.run();
In my case.. following steps resolved:
There was a column value which was set to "Update" - replaced it with Edit (non sql keyword) There was a space in one of the column names (removed the extra space or trim)
Per this PowerShell blog post, you can create an alias to define a ?:
operator:
set-alias ?: Invoke-Ternary -Option AllScope -Description "PSCX filter alias"
filter Invoke-Ternary ([scriptblock]$decider, [scriptblock]$ifTrue, [scriptblock]$ifFalse)
{
if (&$decider) {
&$ifTrue
} else {
&$ifFalse
}
}
Use it like this:
$total = ($quantity * $price ) * (?: {$quantity -le 10} {.9} {.75})
I had the same problem, and "export LC_ALL=c"
didn't work for me.
Try export LC_ALL="en_US.UTF-8"
(it will work).
Download "json simple 1.1 jar" from this https://code.google.com/p/json-simple/downloads/detail?name=json_simple-1.1.jar&can=2&q=
And add the jar file to your lib folder
using JSONValue you can convert LinkedHashMap to json string
I've try install curl-ca-bundle
with brew
, but the package is no available more:
$ brew install curl-ca-bundle
Error: No available formula for curl-ca-bundle
Searching formulae...
Searching taps...
The solution that worked to me on Mac was:
$ cd /usr/local/etc/openssl/certs/
$ sudo curl -O http://curl.haxx.se/ca/cacert.pem
Add this line in your ~/.bash_profile
(or ~/.zshrc
for zsh):
export SSL_CERT_FILE=/usr/local/etc/openssl/certs/cacert.pem
Then update your terminal:
$ source ~/.bash_profile
SELECT date_created
FROM your_table
WHERE DATENAME(dw, date_created) NOT IN ('Saturday', 'Sunday')
Since the value of $var
is the empty string, this:
if [ $var == $var1 ]; then
expands to this:
if [ == abcd ]; then
which is a syntax error.
You need to quote the arguments:
if [ "$var" == "$var1" ]; then
You can also use =
rather than ==
; that's the original syntax, and it's a bit more portable.
If you're using bash, you can use the [[
syntax, which doesn't require the quotes:
if [[ $var = $var1 ]]; then
Even then, it doesn't hurt to quote the variable reference, and adding quotes:
if [[ "$var" = "$var1" ]]; then
might save a future reader a moment trying to remember whether [[
... ]]
requires them.
git config --global mergetool.keepBackup false

As pointed out in other answers, the idea is usually to define an axes for the colorbar to reside in. There are various ways of doing so; one that hasn't been mentionned yet would be to directly specify the colorbar axes at subplot creation with plt.subplots()
. The advantage is that the axes position does not need to be manually set and in all cases with automatic aspect the colorbar will be exactly the same height as the subplots. Even in many cases where images are used the result will be satisfying as shown below.
When using plt.subplots()
, the use of gridspec_kw
argument allows to make the colorbar axes much smaller than the other axes.
fig, (ax, ax2, cax) = plt.subplots(ncols=3,figsize=(5.5,3),
gridspec_kw={"width_ratios":[1,1, 0.05]})
Example:
import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)
fig, (ax, ax2, cax) = plt.subplots(ncols=3,figsize=(5.5,3),
gridspec_kw={"width_ratios":[1,1, 0.05]})
fig.subplots_adjust(wspace=0.3)
im = ax.imshow(np.random.rand(11,8), vmin=0, vmax=1)
im2 = ax2.imshow(np.random.rand(11,8), vmin=0, vmax=1)
ax.set_ylabel("y label")
fig.colorbar(im, cax=cax)
plt.show()
This works well, if the plots' aspect is autoscaled or the images are shrunk due to their aspect in the width direction (as in the above). If, however, the images are wider then high, the result would look as follows, which might be undesired.
A solution to fix the colorbar height to the subplot height would be to use mpl_toolkits.axes_grid1.inset_locator.InsetPosition
to set the colorbar axes relative to the image subplot axes.
import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)
from mpl_toolkits.axes_grid1.inset_locator import InsetPosition
fig, (ax, ax2, cax) = plt.subplots(ncols=3,figsize=(7,3),
gridspec_kw={"width_ratios":[1,1, 0.05]})
fig.subplots_adjust(wspace=0.3)
im = ax.imshow(np.random.rand(11,16), vmin=0, vmax=1)
im2 = ax2.imshow(np.random.rand(11,16), vmin=0, vmax=1)
ax.set_ylabel("y label")
ip = InsetPosition(ax2, [1.05,0,0.05,1])
cax.set_axes_locator(ip)
fig.colorbar(im, cax=cax, ax=[ax,ax2])
plt.show()
Additionally to what NamShubWriter has said, make sure that:
Do not do this:
@Rule
public ExpectedException expectedException;
@Before
public void setup()
{
expectedException = ExpectedException.none();
}
Finally, this blog post clearly illustrates how to assert that a certain exception is thrown.
As Get-Date
returns a DateTime object you are able to compare them directly. An example:
(get-date 2010-01-02) -lt (get-date 2010-01-01)
will return false.
I understand you intention well, I use buffers exclusively too, and occasionally do split if needed.
below is excerpt of my .vimrc
" disable macro, since not used in 90+% use cases
map q <Nop>
" q, close/hide current window, or quit vim if no other window
nnoremap q :if winnr('$') > 1 \|hide\|else\|silent! exec 'q'\|endif<CR>
" qo, close all other window -- 'o' stands for 'only'
nnoremap qo :only<CR>
set hidden
set timeout
set timeoutlen=200 " let vim wait less for your typing!
Which fits my workflow quite well
If
q
was pressed
- hide current window if multiple window open, else try to quit vim.
if
qo
was pressed,
- close all other window, no effect if only one window.
Of course, you can wrap that messy part into a function, eg
func! Hide_cur_window_or_quit_vim()
if winnr('$') > 1
hide
else
silent! exec 'q'
endif
endfunc
nnoremap q :call Hide_cur_window_or_quit_vim()<CR>
Sidenote:
I remap q
, since I do not use macro for editing, instead use :s
, :g
, :v
, and external text processing command if needed, eg, :'{,'}!awk 'some_programm'
, or use :norm! normal-command-here
.
You can set the year range using this option per documentation here http://api.jqueryui.com/datepicker/#option-yearRange
yearRange: '1950:2013', // specifying a hard coded year range
or this way
yearRange: "-100:+0", // last hundred years
From the Docs
Default: "c-10:c+10"
The range of years displayed in the year drop-down: either relative to today's year ("-nn:+nn"), relative to the currently selected year ("c-nn:c+nn"), absolute ("nnnn:nnnn"), or combinations of these formats ("nnnn:-nn"). Note that this option only affects what appears in the drop-down, to restrict which dates may be selected use the minDate and/or maxDate options.
Not with CSS directly, you could set CSS properties via JavaScript based on the internal contents but in the end you would still need to be operating in the definitions of CSS.
This will do what you want. It reads the fourth field into a local variable, and then sets the actual field value to NULL, if the local variable ends up containing an empty string:
LOAD DATA INFILE '/tmp/testdata.txt'
INTO TABLE moo
FIELDS TERMINATED BY ","
LINES TERMINATED BY "\n"
(one, two, three, @vfour, five)
SET four = NULLIF(@vfour,'')
;
If they're all possibly empty, then you'd read them all into variables and have multiple SET statements, like this:
LOAD DATA INFILE '/tmp/testdata.txt'
INTO TABLE moo
FIELDS TERMINATED BY ","
LINES TERMINATED BY "\n"
(@vone, @vtwo, @vthree, @vfour, @vfive)
SET
one = NULLIF(@vone,''),
two = NULLIF(@vtwo,''),
three = NULLIF(@vthree,''),
four = NULLIF(@vfour,'')
;

I am using git for my Ruby on Rails application. First time so...
I created a .bat file for loading my RoR applications with the paths manually typed using this tutorial at "http://www.youtube.com/watch?v=-eFwV8lRu1w" If you are new to Ruby on Rails you might want to check it out as I followed all steps and it works flawlessly after a few trials and errors.
(The .bat file is editable using notepad++ hence no need for the long process whenever you need to edit a path, you can follow these simple process after creating a .bat file following the tutorials on the link above "file is called row.bat".)
insert path below the last path you inputted.
)
During the tutorials I don't remember anything said in regards to using the git command so when starting a new project I had this same problem after installing git. The main issue I had was locating the folder with the bin/git.exe (git.exe did not show up in search using start menu's "search programs and files" ) NOTE I now understood that the location might vary drastically --- see below.
To locate the bin/git.exe i followed this steps
1 left click start menu and locate ->> all programs ->> GitHub inc. 2 right click git shell and select open file location 3 click through folders in the file location for the folder "bin"
(I had 4 folders named 1. IgnoreTemplates_fdbf2020839cde135ff9dbed7d503f8e03fa3ab4 2. lfs-x86_0.5.1 3. PortableGit_c2ba306e536fdf878271f7fe636a147ff37326ad ("bin/exe, found here <<-") 4. PoshGit_869d4c5159797755bc04749db47b166136e59132 )
Copy the full link by clicking on the explorers url (mine was "C:\Users\username\AppData\Local\GitHub\PortableGit_c2ba306e536fdf878271f7fe636a147ff37326ad\bin") open .bat file in notepad++ and paste using instructions on how to add a path to your .bat file from tutorials above. Problem solved!
The simplest way to get the time from datetime without millisecond stack is:
SELECT convert(time(0),getDate())
Use this function begining from SQL SERVER 2016
Select Count(value) From STRING_SPLIT('AAA AAA AAA',' ');
-- Output : 3
When This function used with count function it gives you how many character exists in string
If you can't know the width in advance, then your only possible answer would depend on staging your output in a temporary buffer of some kind. For small reports, just collecting the data and deferring output until the input is bounded would be simplest.
For large reports, an intermediate file may be required if the collected data exceeds reasonable memory bounds.
Once you have the data, then it is simple to post-process it into a report using the idiom printf("%*d", width, value)
for each value.
Alternatively if the output channel permits random access, you could just go ahead and write a draft of the report that assumes a (short) default width, and seek back and edit it any time your width assumption is violated. This also assumes that you can pad the report lines outside that field in some innocuous way, or that you are willing to replace the output so far by a read-modify-write process and abandon the draft file.
But unless you can predict the correct width in advance, it will not be possible to do what you want without some form of two-pass algorithm.
In my case, I was using a View that I´ve converted to partial view and I forgot to remove the template from "@section scripts". Removing the section block, solved my problem. This is because the sections aren´t rendered in partial views.
Exception
is a checked exception class. Therefore, any code that calls a method that declares that it throws Exception
must handle or declare it.
If you create an object, you get a more readable output and also gain an object with properties you can access:
$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NETFramework'
$obj = New-Object -TypeName psobject
Get-Item -Path $path | Select-Object -ExpandProperty Property | Sort | % {
$command = [String]::Format('(Get-ItemProperty -Path "{0}" -Name "{1}")."{1}"', $path, $_)
$value = Invoke-Expression -Command $command
$obj | Add-Member -MemberType NoteProperty -Name $_ -Value $value}
Write-Output $obj | fl
Sample output: InstallRoot : C:\Windows\Microsoft.NET\Framework\
And the object: $obj.InstallRoot = C:\Windows\Microsoft.NET\Framework\
The truth of the matter is this is way more complicated than it needs to be. Here is a much better example, and much simpler:
$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NETFramework'
$objReg = Get-ItemProperty -Path $path | Select -Property *
$objReg is now a custom object where each registry entry is a property name. You can view the formatted list via:
write-output $objReg
InstallRoot : C:\Windows\Microsoft.NET\Framework\
DbgManagedDebugger : "C:\windows\system32\vsjitdebugger.exe"
And you have access to the object itself:
$objReg.InstallRoot
C:\Windows\Microsoft.NET\Framework\
You probably need to add the namespace:
<Window x:Class="UserControlTest.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

JSONArray objects have a function getJSONObject(int index)
, you can loop through all of the JSONObjects by writing a simple for-loop:
JSONArray array;
for(int n = 0; n < array.length(); n++)
{
JSONObject object = array.getJSONObject(n);
// do some stuff....
}
new Date().toString().split(" ")[4];
result 15:08:03
GridView
is used for implementing material grid lists. If you know you have a fixed number of items and it's not very many (16 is fine), you can use GridView.count
. However, you should note that a GridView
is scrollable, and if that isn't what you want, you may be better off with just rows and columns.

If the solutions proposed here aren't working for you, and your image asset is actually a PDF, note that XCode actually treats PDFs differently than image files. In particular, it doesn't seem able to scale to fill properly with a PDF: it ends up tiled instead. This drove me crazy until I figured out that the issue was the PDF format. Convert to JPG and you should be good to go.
cache.db
is being currently used by another process.add:
margin: 0 0 3px 0;
to your #access li
and move
background: #0f84e8; /* Show a solid color for older browsers */
to the #access a
and take out the border-bottom
. Then it will work
Goto the Start Menu Right Click "Computer" Select "Properties" A dialog should pop up with a link on the left called "Advanced system settings". Click it. In the System Properties dialog, click the button called "Environment Variables". In the Environment Variables dialog look for "Path" under the System Variables window. Add ";C:\Python27" to the end of it. The semicolon is the path separator on windows. Click Ok and close the dialogs. Now open up a new command prompt and type "python"
If still the problem persists then type "py" instead of "python" in command prompt. might help!!!!
If you only want to import a certificate in PEM format into a keystore, keytool will do the job:
keytool -import -alias *alias* -keystore cacerts -file *cert.pem*
In Node.js, __dirname
is always the directory in which the currently executing script resides (see this). So if you typed __dirname
into /d1/d2/myscript.js
, the value would be /d1/d2
.
By contrast, .
gives you the directory from which you ran the node
command in your terminal window (i.e. your working directory) when you use libraries like path
and fs
. Technically, it starts out as your working directory but can be changed using process.chdir()
.
The exception is when you use .
with require()
. The path inside require
is always relative to the file containing the call to require
.
Let's say your directory structure is
/dir1
/dir2
pathtest.js
and pathtest.js
contains
var path = require("path");
console.log(". = %s", path.resolve("."));
console.log("__dirname = %s", path.resolve(__dirname));
and you do
cd /dir1/dir2
node pathtest.js
you get
. = /dir1/dir2
__dirname = /dir1/dir2
Your working directory is /dir1/dir2
so that's what .
resolves to. Since pathtest.js
is located in /dir1/dir2
that's what __dirname
resolves to as well.
However, if you run the script from /dir1
cd /dir1
node dir2/pathtest.js
you get
. = /dir1
__dirname = /dir1/dir2
In that case, your working directory was /dir1
so that's what .
resolved to, but __dirname
still resolves to /dir1/dir2
.
.
inside require
...If inside dir2/pathtest.js
you have a require
call into include a file inside dir1
you would always do
require('../thefile')
because the path inside require
is always relative to the file in which you are calling it. It has nothing to do with your working directory.
If you already have python3 installed as well virtualenvwrapper the only thing you would need to do to use python3 with the virtual environment is creating an environment using:
which python3 #Output: /usr/bin/python3
mkvirtualenv --python=/usr/bin/python3 nameOfEnvironment
Or, (at least on OSX using brew):
mkvirtualenv --python=`which python3` nameOfEnvironment
Start using the environment and you'll see that as soon as you type python you'll start using python3
For those of you using AngularUI Router instead of ngRoute can use the following code to track page views.
app.run(function ($rootScope) {
$rootScope.$on('$stateChangeSuccess', function (event, toState, toParams, fromState, fromParams) {
ga('set', 'page', toState.url);
ga('send', 'pageview');
});
});
You can add multiple base packages (see axtavt's answer), but you can also filter what's scanned inside the base package:
<context:component-scan base-package="x.y.z">
<context:include-filter type="regex" expression="(service|controller)\..*"/>
</context:component-scan>
To get all the differences between two tables, you can use like me this SQL request :
SELECT 'TABLE1-ONLY' AS SRC, T1.*
FROM (
SELECT * FROM Table1
EXCEPT
SELECT * FROM Table2
) AS T1
UNION ALL
SELECT 'TABLE2-ONLY' AS SRC, T2.*
FROM (
SELECT * FROM Table2
EXCEPT
SELECT * FROM Table1
) AS T2
;
As stated in other answers before; while this cannot be expressed in source-code it can actually be done on IL Level. @Christopher Currens answer shows how the IL do to that.
With Fodys Add-In ExtraConstraints.Fody there's a very simple way, complete with build-tooling, to achieve this. Just add their nuget packages (Fody
, ExtraConstraints.Fody
) to your project and add the constraints as follows (Excerpt from the Readme of ExtraConstraints):
public void MethodWithEnumConstraint<[EnumConstraint] T>() {...}
public void MethodWithTypeEnumConstraint<[EnumConstraint(typeof(ConsoleColor))] T>() {...}
and Fody will add the necessary IL for the constraint to be present. Also note the additional feature of constraining delegates:
public void MethodWithDelegateConstraint<[DelegateConstraint] T> ()
{...}
public void MethodWithTypeDelegateConstraint<[DelegateConstraint(typeof(Func<int>))] T> ()
{...}
Regarding Enums, you might also want to take note of the highly interesting Enums.NET.
Differences might not be meaningful in a typical use case, but using the standard DOM functionality
$("#el")[0].outerHTML
is about twice as fast as
$("<div />").append($("#el").clone()).html();
so I would go with:
/*
* Return outerHTML for the first element in a jQuery object,
* or an empty string if the jQuery object is empty;
*/
jQuery.fn.outerHTML = function() {
return (this[0]) ? this[0].outerHTML : '';
};
You can do it in componentDidMount()
lifecycle method in following way
componentDidMount(){
const buttonElement = document.querySelector(".rsc-submit-button");
const inputElement = document.querySelector(".rsc-input");
buttonElement.setAttribute('aria-hidden', 'true');
inputElement.setAttribute('aria-label', 'input');
}
This is basically the same answer provided by Evert, but extended to show-off

I was getting undefined after setting a system env var. When I put APP_VERSION in the User env var, then I can display the value from node via process.env.APP_VERSION
volatile
in C actually came into existence for the purpose of not caching the values of the variable automatically. It will tell the compiler not to cache the value of this variable. So it will generate code to take the value of the given volatile
variable from the main memory every time it encounters it. This mechanism is used because at any time the value can be modified by the OS or any interrupt. So using volatile
will help us accessing the value afresh every time.
You can check how this query works following this link.

Try avoiding unnecessary loops and go for this if needed.
string SearchByColumn = "ColumnName=" + value;
DataRow[] hasRows = currentDataTable.Select(SearchByColumn);
if (hasRows.Length == 0)
{
//your logic goes here
}
else
{
//your logic goes here
}
If you want to search by specific ID then there should be a primary key in a table.
Accept:text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8
That should be the problem. JSON is served as application/json
. If you set the Accept header accordingly, you should get the proper response. (There are browser plugins that let you set headers, I like "Poster" for Firefox best)
Note that :
typeof $(this)
is JQuery object.
and
typeof $(this)[0]
is HTMLElement object
then :
if you want to apply .val()
on HTMLElement , you can add this extension .
HTMLElement.prototype.val=function(v){
if(typeof v!=='undefined'){this.value=v;return this;}
else{return this.value}
}
Then :
document.getElementById('myDiv').val() ==== $('#myDiv').val()
And
document.getElementById('myDiv').val('newVal') ==== $('#myDiv').val('newVal')
?????
INVERSE :Conversely? if you want to add value property to jQuery object , follow those steps :
Download the full source code (not minified) i.e: example http://code.jquery.com/jquery-1.11.1.js .
Insert Line after L96 , add this code value:""
to init this new prop
Search on jQuery.fn.init
, it will be almost Line 2747
value
prop : (Before return statment add this.value=jQuery(selector).val()
)
