You want to loop on the .Rows, and access the column for the row like q("column")
Just:
For Each q In dtDataTable.Rows
strDetail = q("Detail")
Next
Also make sure to check msdn doc for any class you are using + use intellisense
Collating possible solutions from the answers:
For IN: df[df['A'].isin([3, 6])]
For NOT IN:
df[-df["A"].isin([3, 6])]
df[~df["A"].isin([3, 6])]
df[df["A"].isin([3, 6]) == False]
df[np.logical_not(df["A"].isin([3, 6]))]
The right choice really depends on how big the input string is and what the perforce and memory requirement are, but I would use a regular expression like
string result = Regex.Replace(s, @"\r\n?|\n|\t", String.Empty);
Or if we need to apply the same replacement multiple times, it is better to use a compiled version for the Regex like
var regex = new Regex(@"\r\n?|\n|\t", RegexOptions.Compiled);
string result = regex.Replace(s, String.Empty);
NOTE: different scenarios requite different approaches to achieve the best performance and the minimum memory consumption

I also believe this could be done dynamically for any screen if using canvas to copy the current dom and blurring it.
Since I can't comment. There is one more issue with the accepted solution where bank holidays are subtracted even when they are situated in the weekend. Seeing how other input is checked, it is only fitting that this is as well.
The foreach should therefore be:
// subtract the number of bank holidays during the time interval
foreach (DateTime bankHoliday in bankHolidays)
{
DateTime bh = bankHoliday.Date;
// Do not subtract bank holidays when they fall in the weekend to avoid double subtraction
if (bh.DayOfWeek == DayOfWeek.Saturday || bh.DayOfWeek == DayOfWeek.Sunday)
continue;
if (firstDay <= bh && bh <= lastDay)
--businessDays;
}
As Marcelo suggests:
UPDATE mytable
SET new_column = <expr containing old_column>;
If this takes too long and fails due to "snapshot too old" errors (e.g. if the expression queries another highly-active table), and if the new value for the column is always NOT NULL, you could update the table in batches:
UPDATE mytable
SET new_column = <expr containing old_column>
WHERE new_column IS NULL
AND ROWNUM <= 100000;
Just run this statement, COMMIT, then run it again; rinse, repeat until it reports "0 rows updated". It'll take longer but each update is less likely to fail.
EDIT:
A better alternative that should be more efficient is to use the DBMS_PARALLEL_EXECUTE
API.
Sample code (from Oracle docs):
DECLARE
l_sql_stmt VARCHAR2(1000);
l_try NUMBER;
l_status NUMBER;
BEGIN
-- Create the TASK
DBMS_PARALLEL_EXECUTE.CREATE_TASK ('mytask');
-- Chunk the table by ROWID
DBMS_PARALLEL_EXECUTE.CREATE_CHUNKS_BY_ROWID('mytask', 'HR', 'EMPLOYEES', true, 100);
-- Execute the DML in parallel
l_sql_stmt := 'update EMPLOYEES e
SET e.salary = e.salary + 10
WHERE rowid BETWEEN :start_id AND :end_id';
DBMS_PARALLEL_EXECUTE.RUN_TASK('mytask', l_sql_stmt, DBMS_SQL.NATIVE,
parallel_level => 10);
-- If there is an error, RESUME it for at most 2 times.
l_try := 0;
l_status := DBMS_PARALLEL_EXECUTE.TASK_STATUS('mytask');
WHILE(l_try < 2 and l_status != DBMS_PARALLEL_EXECUTE.FINISHED)
LOOP
l_try := l_try + 1;
DBMS_PARALLEL_EXECUTE.RESUME_TASK('mytask');
l_status := DBMS_PARALLEL_EXECUTE.TASK_STATUS('mytask');
END LOOP;
-- Done with processing; drop the task
DBMS_PARALLEL_EXECUTE.DROP_TASK('mytask');
END;

This has worked for me:
System.out.println((char)27 + "[31mThis text would show up red" + (char)27 + "[0m");
You need the ending "[37m" to return the color to white (or whatever you were using). If you don't it may make everything that follows "red".
css3-mediaqueries-js is probably what you are looking for: this script emulates media queries. However (from the script's site) it "doesn't work on @import
ed stylesheets (which you shouldn't use anyway for performance reasons). Also won't listen to the media attribute of the <link>
and <style>
elements".
In the same vein you have the simpler Respond.js, which enables only min-width
and max-width
media queries.
Python 3
import openpyxl as xl
wb = xl.load_workbook("Sample.xlsx", enumerate)
#the 2 lines under do the same.
sheet = wb.get_sheet_by_name('sheet')
sheet = wb.worksheets[0]
row_count = sheet.max_row
column_count = sheet.max_column
#this works fore me.
For me the biggest win on Criteria is the Example API, where you can pass an object and hibernate will build a query based on those object properties.
Besides that, the criteria API has its quirks (I believe the hibernate team is reworking the api), like:
I tend to use HQL when I want queries similar to sql (delete from Users where status='blocked'), and I tend to use criteria when I don't want to use string appending.
Another advantage of HQL is that you can define all your queries before hand, and even externalise them to a file or so.
You can put conditionals inside tags. Try:
ng-class="{true:'active',false:'disable'}[list_status=='show']"
Is it possible to add onclick to a div and have it occur if any area of the div is clicked.
Yes … although it should be done with caution. Make sure there is some mechanism that allows keyboard access. Build on things that work
If yes then why is the onclick method not going through to my div.
You are assigning a string where a function is expected.
divTag.onclick = printWorking;
There are nicer ways to assign event handlers though, although older versions of Internet Explorer are sufficiently different that you should use a library to abstract it. There are plenty of very small event libraries and every major library jQuery) has event handling functionality.
That said, now it is 2019, older versions of Internet Explorer no longer exist in practice so you can go direct to addEventListener
My issue was, i am unable to create a view with my "scott" user in oracle 11g edition. So here is my solution for this
Error in my case
SQL>create view v1 as select * from books where id=10;
insufficient privileges.
Solution
1)open your cmd and change your directory to where you install your oracle database. in my case i was downloaded in E drive so my location is E:\app\B_Amar\product\11.2.0\dbhome_1\BIN> after reaching in the position you have to type sqlplus sys as sysdba
E:\app\B_Amar\product\11.2.0\dbhome_1\BIN>sqlplus sys as sysdba
2) Enter password: here you have to type that password that you give at the time of installation of oracle software.
3) Here in this step if you want create a new user then you can create otherwise give all the privileges to existing user.
for creating new user
SQL> create user abc identified by xyz;
here abc is user and xyz is password.
giving all the privileges to abc user
SQL> grant all privileges to abc;
grant succeeded.
if you are seen this message then all the privileges are giving to the abc user.
4) Now exit from cmd, go to your SQL PLUS and connect to the user i.e enter your username & password.Now you can happily create view.
In My case
in cmd E:\app\B_Amar\product\11.2.0\dbhome_1\BIN>sqlplus sys as sysdba
SQL> grant all privileges to SCOTT;
grant succeeded.
Now I can create views.
Or use good old "find". For example in order to look for old mysql v5.7:
cd /
find . type -d -name "[email protected]"
Set the insetForSectionAt
property of the UICollectionViewFlowLayout
object attached to your UICollectionView
Make sure to add this protocol
UICollectionViewDelegateFlowLayout
Swift
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
return UIEdgeInsets (top: top, left: left, bottom: bottom, right: right)
}
Objective - C
- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section{
return UIEdgeInsetsMake(top, left, bottom, right);
}
A quick tip that tripped me up: if you're invoking the linker as "gcc" or "g++", then using "--start-group" and "--end-group" won't pass those options through to the linker -- nor will it flag an error. It will just fail the link with undefined symbols if you had the library order wrong.
You need to write them as "-Wl,--start-group" etc. to tell GCC to pass the argument through to the linker.
Please note that the proposed code is only valid with Python 2

It does not yet have the mouse wheel bound to the scrollbar but it is possible. Scrolling with the wheel can get a bit bumpy, though.
edit:
to 1)
IMHO scrolling frames is somewhat tricky in Tkinter and does not seem to be done a lot. It seems there is no elegant way to do it.
One problem with your code is that you have to set the canvas size manually - that's what the example code I posted solves.
to 2)
You are talking about the data function? Place works for me, too. (In general I prefer grid).
to 3)
Well, it positions the window on the canvas.
One thing I noticed is that your example handles mouse wheel scrolling by default while the one I posted does not. Will have to look at that some time.
Here is a version based on the accepted answer. It fixes two problems...

For WAMP server, comment given by "Enrique" solved my problem.
wamp is using this php.ini:
c:\wamp\bin\apache\Apache2.4.4\bin\php.ini
But composer is using PHP from CLI, and hence it's reading this file:
c:\wamp\bin\php\php5.4.12\php.ini (so you need to enable openssl there)
For composer you will have to enable extension in
c:\wamp\bin\php\php5.4.12\php.ini
Change:
;extension=php_openssl.dll
to
extension=php_openssl.dll

When resetting root password at step 2), also change the auth plugin to mysql_native_password
:
use mysql;
update user set authentication_string=PASSWORD("") where User='root';
update user set plugin="mysql_native_password" where User='root'; # THIS LINE
flush privileges;
quit;
This allowed me to log in successfully!
sudo /etc/init.d/mysql stop # stop mysql service
sudo mysqld_safe --skip-grant-tables & # start mysql without password
# enter -> go
mysql -uroot # connect to mysql
use mysql; # use mysql table
update user set authentication_string=PASSWORD("") where User='root'; # update password to nothing
update user set plugin="mysql_native_password" where User='root'; # set password resolving to default mechanism for root user
flush privileges;
quit;
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start # reset mysql
# try login to database, just press enter at password prompt because your password is now blank
mysql -u root -p
When you see a socket error, a community came with 2 possible solutions:
sudo mkdir -p /var/run/mysqld; sudo chown mysql /var/run/mysqld
sudo mysqld_safe --skip-grant-tables &

Or
mkdir -p /var/run/mysqld && chown mysql:mysql /var/run/mysqld
(thanks to @Peter Dvukhrechensky)
mysql -uroot # "-hlocalhost" is default

The limit
was the clue for my code, but I had to specify it like this:
use: [
{
loader: 'url-loader',
options: {
limit: 8192,
},
},
],
In my case, I get two objects in and I don't know if it's date or timedate objects. Converting to date won't be good as I'd be dropping information - two timedate objects with the same date should be sorted correctly. I'm OK with the dates being sorted before the datetime with same date.
I think I will use strftime before comparing:
>>> foo=datetime.date(2015,1,10)
>>> bar=datetime.datetime(2015,2,11,15,00)
>>> foo.strftime('%F%H%M%S') > bar.strftime('%F%H%M%S')
False
>>> foo.strftime('%F%H%M%S') < bar.strftime('%F%H%M%S')
True
Not elegant, but should work out. I think it would be better if Python wouldn't raise the error, I see no reasons why a datetime shouldn't be comparable with a date. This behaviour is consistent in python2 and python3.
You need to retrieve and disect the information into what you need.
while($row = mysql_fetch_array($result)) {
echo "img src='",$row['filename'],"' width='175' height='200' />";
}
If you go into any of those locations, then you will find what is defined in those schema. For example, it tells you what is the data type of the ini-method key words value.
A primary key has the semantic of identifying the row of a database. Therefore there can be only one primary key for a given table, while there can be many unique keys.
Also for the same reason a primary key cannot be NULL (at least in Oracle, not sure about other databases)
Since it identifies the row it should never ever change. Changing primary keys are bound to cause serious pain and probably eternal damnation.
Therefor in most cases you want some artificial id for primary key which isn't used for anything but identifying single rows in the table.
Unique keys on the other hand may change as much as you want.
You can use:
[Min(0)]
This will impose a required minimum value of 0 (zero), and no maximum value.
You need DataAnnotationsExtensions to use this.
If the first column is always the same size (including the spaces), then you can just take those characters (via LEFT
) and clean up the spaces (with RTRIM
):
SELECT RTRIM(LEFT(YourColumn, YourColumnSize))
Alternatively, you can extract the second (or third, etc.) column (using SUBSTRING
):
SELECT RTRIM(SUBSTRING(YourColumn, PreviousColumnSizes, YourColumnSize))
One benefit of this approach (especially if YourColumn
is the result of a computation) is that YourColumn
is only specified once.
first convert your array too JSON
while($query->fetch()){
$col[] = json_encode($row,JSON_UNESCAPED_UNICODE);
}
then vonvert back it to array
foreach($col as &$array){
$array = json_decode($array,true);
}
good luck
Warning messages should be written using the Write-Warning
cmdlet, which allows the warning messages to be suppressed with the -WarningAction
parameter or the $WarningPreference
automatic variable. A function needs to use CmdletBinding
to implement this feature.
function WarningTest {
[CmdletBinding()]
param($n)
Write-Warning "This is a warning message for: $n."
"Parameter n = $n"
}
$a = WarningTest 'test one' -WarningAction SilentlyContinue
# To turn off warnings for multiple commads,
# use the WarningPreference variable
$WarningPreference = 'SilentlyContinue'
$b = WarningTest 'test two'
$c = WarningTest 'test three'
# Turn messages back on.
$WarningPreference = 'Continue'
$c = WarningTest 'test four'
To make it shorter at the command prompt, you can use -wa 0
:
PS> WarningTest 'parameter alias test' -wa 0
Write-Error, Write-Verbose and Write-Debug offer similar functionality for their corresponding types of messages.
Use the CAST

MY FAVORITE WAY TO DO IT
1. Open info.plist
2. Click this button to add a new key
3. Scroll down to find Privacy - Photo Library Usage Description
4. Select it, then add your description on the right
You can pass the parameter(s) as a property of the function object, not as a parameter:
var f = this.someFunction; //use 'this' if called from class
f.parameter1 = obj;
f.parameter2 = this;
f.parameter3 = whatever;
setInterval(f, 1000);
Then in your function someFunction
, you will have access to the parameters. This is particularly useful inside classes where the scope goes to the global space automatically and you lose references to the class that called setInterval to begin with. With this approach, "parameter2" in "someFunction", in the example above, will have the right scope.

If the container has already exited (maybe due to some error), you can do
$ docker run --rm -it --entrypoint /bin/ash image_name
or
$ docker run --rm -it --entrypoint /bin/sh image_name
or
$ docker run --rm -it --entrypoint /bin/bash image_name
to create a new container and get a shell into it. Since you specified --rm, the container would be deleted when you exit the shell.
#if !defined(MANUF) || !defined(SERIAL) || !defined(MODEL)
You need to provide a body for the get;
portion as well as the set;
portion of the property.
I suspect you want this to be:
private int _hour; // backing field
private int Hour
{
get { return _hour; }
set
{
//make sure hour is positive
if (value < MIN_HOUR)
{
_hour = 0;
MessageBox.Show("Hour value " + value.ToString() + " cannot be negative. Reset to " + MIN_HOUR.ToString(),
"Invalid Hour", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
else
{
//take the modulus to ensure always less than 24 hours
//works even if the value is already within range, or value equal to 24
_hour = value % MAX_HOUR;
}
}
}
That being said, I'd also consider making this code simpler. It's probably is better to use exceptions rather than a MessageBox inside of your property setter for invalid input, as it won't tie you to a specific UI framework.
If that is inappropriate, I would recommend converting this to a method instead of using a property setter. This is especially true since properties have an implicit expectation of being "lightweight"- and displaying a MessageBox to the user really violates that expectation.
For systemd style init scripts it's really easy. You just add a User= in the [Service] section.

Javascript which runs on the client machine can't access the local disk file system due to security restrictions.
If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

I do this in a more permanent way - instead of installing the APKs each time with adb
, permanently add them to the system image that the emulator uses. You will need Yaffey on Windows, or a similar utility on other systems, to modify YAFFS2 images. Copy GoogleLoginService.apk
, GoogleServicesFramework.apk
, and Phonesky.apk
(or Vending.apk
in older versions of Android) to the /system/app
folder of the system.img
file of the emulator. Afterwards I can start the emulator normally, without messing with adb, and Play Store is always there.
Downloading Google Apps from some Internet site may not be quite legal, but if you have a phone or tablet with a corresponding Android version, just pull them out of your device:
adb -d root
adb -d pull /system/app/GoogleLoginService.apk
adb -d pull /system/app/GoogleServicesFramework.apk
adb -d pull /system/app/Phonesky.apk
You must have root-level access (run adb root) to the device in order to pull these files from it.
Now start yaffey
on Windows or a similar utility on Linux or Mac, and open system.img
for the emulator image you want to modify. I modify most often the one in [...]\android-sdk\system-images\android-17\x86
.
Rename the original system.img
to system-original.img
. Under yaffey, copy the APK files you pulled from your device to /app folder. Save your modified image as system.img
in the original folder. Then start your emulator (in my case it would be Android 4.2 emulator with Intel Atom processor running under Intel HAX, super-fast on Windows machines) and you'll have Play Store there. I did not find it necessary to delete SdkSetup.apk
and SdkSetup.odex
- the Play Store and other services still work fine for me with these files present.
When finished with your testing, to alleviate your conscience guilty of temporarily pirating the Google Apps from your device, you may delete the modified system.img
and restore the original from system-original.img
.
In my very specific case, I just wanted to execute a command in a remote host, inside a specific directory from a Jenkins slave machine:
ssh myuser@mydomain
cd /home/myuser/somedir
./commandThatMustBeRunInside_somedir
exit
But my machine couldn't perform the ssh (it couldn't allocate a pseudo-tty I suppose) and kept me giving the following error:
Pseudo-terminal will not be allocated because stdin is not a terminal
I could get around this issue passing "cd to dir + my command" as a parameter of the ssh command (to not have to allocate a Pseudo-terminal) and by passing the option -T to explicitly tell to the ssh command that I didn't need pseudo-terminal allocation.
ssh -T myuser@mydomain "cd /home/myuser/somedir; ./commandThatMustBeRunInside_somedir"
Varargs can be used when we are unsure about the number of arguments to be passed in a method. It creates an array of parameters of unspecified length in the background and such a parameter can be treated as an array in runtime.
If we have a method which is overloaded to accept different number of parameters, then instead of overloading the method different times, we can simply use varargs concept.
Also when the parameters' type is going to vary then using "Object...test" will simplify the code a lot.
For example:
public int calculate(int...list) {
int sum = 0;
for (int item : list) {
sum += item;
}
return sum;
}
Here indirectly an array of int type (list) is passed as parameter and is treated as an array in the code.
For a better understanding follow this link(it helped me a lot in understanding this concept clearly): http://www.javadb.com/using-varargs-in-java
P.S: Even I was afraid of using varargs when I didn't knw abt it. But now I am used to it. As it is said: "We cling to the known, afraid of the unknown", so just use it as much as you can and you too will start liking it :)
Sure. In this case, you'd just do:
length_key = len(d['key']) # length of the list stored at `'key'` ...
It's hard to say why you actually want this, but, perhaps it would be useful to create another dict that maps the keys to the length of values:
length_dict = {key: len(value) for key, value in d.items()}
length_key = length_dict['key'] # length of the list stored at `'key'` ...
//an easy way:
str := fmt.Sprint(data)
If you use DisplayFor
, then you have to either define the format via the DisplayFormat
attribute or use a custom display template. (A full list of preset DisplayFormatString
's can be found here.)
[DisplayFormat(DataFormatString = "{0:d}")]
public DateTime? AuditDate { get; set; }
Or create the view Views\Shared\DisplayTemplates\DateTime.cshtml
:
@model DateTime?
@if (Model.HasValue)
{
@Model.Value.ToString("MM/dd/yyyy")
}
That will apply to all DateTime
s, though, even ones where you're encoding the time as well. If you want it to apply only to date-only properties, then use Views\Shared\DisplayTemplates\Date.cshtml
and the DataType
attribute on your property:
[DataType(DataType.Date)]
public DateTime? AuditDate { get; set; }
The final option is to not use DisplayFor
and instead render the property directly:
@if (Model.AuditDate.HasValue)
{
@Model.AuditDate.Value.ToString("MM/dd/yyyy")
}
Sorry, but I have to chime in. I have been through several of the suggested solutions, before finding the Prism.Wpf.Interactivity namespace in the Prism project. You can use interaction requests and popup window action to either roll a custom window or for simpler needs there are built in Notification and Confirmation popups. These create true windows and are managed as such. you can pass a context object with any dependencies you need in the dialog. We use this solution at my work since I found it. We have numerous senior devs here and noone has come up with anything better. Our previous solution was the dialog service into an overlay and using a presenter class to make it happen, but you had to have factories for all of the dialog viewmodels, etc.
This isn't trivial but it also isn't super complicated. And it is built in to Prism and is therefore best (or better) practice IMHO.
My 2 cents!
I recommend more understanding way using extension method:
public static class KeyValuePairExtensions
{
public static bool IsNull<T, TU>(this KeyValuePair<T, TU> pair)
{
return pair.Equals(new KeyValuePair<T, TU>());
}
}
And then just use:
var countries = new Dictionary<string, string>
{
{"cz", "prague"},
{"de", "berlin"}
};
var country = countries.FirstOrDefault(x => x.Key == "en");
if(country.IsNull()){
}
you can simply write the following command in the terminal of your linux system and get the java path :- echo $JAVA_HOME
it just means that the array, $_POST in this case, doesn't have an element named what is undefined in your error. PHP issues a NOTICE instead of a WARNING of FATAL ERROR.
You can either log less events via editing php.ini or deal with it by first checking if the items is indeed initialized already by using isset()
I recommend looking at modern databases like NoSQL and also I agree with user1252434's post. For instance I am storing a few < 500kb PNGs as base64 on my Mongo db with binary set to true with no performance hit at all. Mongo can be used to store large files like 10MB videos and that can offer huge time saving advantages in metadata searches for those videos, see storing large objects and files in mongodb.
The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity
changes.
Instead you could try the following approach. Change your markup to the following:
<div ng-controller="myAppController" style="text-align:center">
<p style="font-size:28px;">Enter Quantity:
<input type="text" ng-model="quantity"/>
</p>
<button ng-click="calculateQuantity()">Calculate</button>
<h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>
Next, update your controller:
myAppModule.controller('myAppController', function($scope,calculateService) {
$scope.quantity=1;
$scope.quantityResult = 0;
$scope.calculateQuantity = function() {
$scope.quantityResult = calculateService.calculate($scope.quantity, 10);
};
});
Here's a JSBin example that demonstrates the above approach.
The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity
changes.
This would involve updating the template to add an ng-change
on the input, and an ng-if
on the result:
<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>
and
<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>
In the controller add:
$scope.showQuantityResult = false;
$scope.calculateQuantity = function() {
$scope.quantityResult = calculateService.calculate($scope.quantity, 10);
$scope.showQuantityResult = true;
};
$scope.hideQuantityResult = function() {
$scope.showQuantityResult = false;
};
These updates can be seen in this JSBin demo.
You get this message when you've used async in your template, but are referring to an object that isn't an Observable.
So for examples sake, lets' say I had these properties in my class:
job:Job
job$:Observable<Job>
Then in my template, I refer to it this way:
{{job | async }}
instead of:
{{job$ | async }}
You wouldn't need the job:Job property if you use the async pipe, but it serves to illustrate a cause of the error.
Just got a solution to get height and width of a custom view:
@Override
protected void onSizeChanged(int xNew, int yNew, int xOld, int yOld){
super.onSizeChanged(xNew, yNew, xOld, yOld);
viewWidth = xNew;
viewHeight = yNew;
}
Its working in my case.
As you are reading a book about NLTK it would be interesting you read about MaxEnt Classifier Module http://www.nltk.org/api/nltk.classify.html#module-nltk.classify.maxent
For text mining classification the steps could be: pre-processing (tokenization, steaming, feature selection with Information Gain ...), transformation to numeric (frequency or TF-IDF) (I think that this is the key step to understand when using text as input to a algorithm that only accept numeric) and then classify with MaxEnt, sure this is just an example.
I just want to say, make sure the csrf token is generated, sometimes it's just an empty array, like for example in a repeater form if you don't generated inside the js query.
Here is an example I used to connect node.js to my Postgres database.
The interface in node.js that I used can be found here https://github.com/brianc/node-postgres
var pg = require('pg');
var conString = "postgres://YourUserName:YourPassword@localhost:5432/YourDatabase";
var client = new pg.Client(conString);
client.connect();
//queries are queued and executed one after another once the connection becomes available
var x = 1000;
while (x > 0) {
client.query("INSERT INTO junk(name, a_number) values('Ted',12)");
client.query("INSERT INTO junk(name, a_number) values($1, $2)", ['John', x]);
x = x - 1;
}
var query = client.query("SELECT * FROM junk");
//fired after last row is emitted
query.on('row', function(row) {
console.log(row);
});
query.on('end', function() {
client.end();
});
//queries can be executed either via text/parameter values passed as individual arguments
//or by passing an options object containing text, (optional) parameter values, and (optional) query name
client.query({
name: 'insert beatle',
text: "INSERT INTO beatles(name, height, birthday) values($1, $2, $3)",
values: ['George', 70, new Date(1946, 02, 14)]
});
//subsequent queries with the same name will be executed without re-parsing the query plan by postgres
client.query({
name: 'insert beatle',
values: ['Paul', 63, new Date(1945, 04, 03)]
});
var query = client.query("SELECT * FROM beatles WHERE name = $1", ['john']);
//can stream row results back 1 at a time
query.on('row', function(row) {
console.log(row);
console.log("Beatle name: %s", row.name); //Beatle name: John
console.log("Beatle birth year: %d", row.birthday.getYear()); //dates are returned as javascript dates
console.log("Beatle height: %d' %d\"", Math.floor(row.height / 12), row.height % 12); //integers are returned as javascript ints
});
//fired after last row is emitted
query.on('end', function() {
client.end();
});
UPDATE:- THE query.on
function is now deprecated and hence the above code will not work as intended. As a solution for this look at:- query.on is not a function

Note that if the user may be in multiple zones used in the query, you may probably want to add .distinct()

users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3]).distinct()

*scanf()
family of functions return the number of values converted. So you should check to make sure sscanf()
returns 1 in your case. EOF
is returned for "input failure", which means that ssacnf()
will never return EOF
.
For sscanf()
, the function has to parse the format string, and then decode an integer. atoi()
doesn't have that overhead. Both suffer from the problem that out-of-range values result in undefined behavior.
You should use strtol()
or strtoul()
functions, which provide much better error-detection and checking. They also let you know if the whole string was consumed.
If you want an int
, you can always use strtol()
, and then check the returned value to see if it lies between INT_MIN
and INT_MAX
.
Here is the minimal change to the original proposal to create a valid daemon in Bourne shell (or Bash):
#!/bin/sh
if [ "$1" != "__forked__" ]; then
setsid "$0" __forked__ "$@" &
exit
else
shift
fi
trap 'siguser1=true' SIGUSR1
trap 'echo "Clean up and exit"; kill $sleep_pid; exit' SIGTERM
exec > outfile
exec 2> errfile
exec 0< /dev/null
while true; do
(sleep 30000000 &>/dev/null) &
sleep_pid=$!
wait
kill $sleep_pid &>/dev/null
if [ -n "$siguser1" ]; then
siguser1=''
echo "Wait was interrupted by SIGUSR1, do things here."
fi
done
Explanation:
Guess it does not get any simpler than that.
If you want to make it clear what each of the parameters are, rather than just calling
someFunction(70, 115);
why not do the following
var width = 70, height = 115;
someFunction(width, height);
sure, it's an extra line of code, but it wins on readability.
Please use ListFragment
. Otherwise, it won't work.
EDIT 1:
Then you'll only need setListAdapter()
and getListView()
.
Remember to pipe Observables to async, like *ngFor item of items$ | async
, where you are trying to *ngFor item of items$
where items$
is obviously an Observable because you notated it with the $
similar to items$: Observable<IValuePair>
, and your assignment may be something like this.items$ = this.someDataService.someMethod<IValuePair>()
which returns an Observable of type T.
Adding to this... I believe I have used notation like *ngFor item of (items$ | async)?.someProperty

You can either use javascript url form with
<form action="javascript:handleClick()">
Or use onSubmit event handler
<form onSubmit="return handleClick()">
In the later form, if you return false from the handleClick it will prevent the normal submision procedure. Return true if you want the browser to follow normal submision procedure.
Your onSubmit event handler in the button also fails because of the Javascript:

Make sure you have selected your mysql storage engine as Innodb and not MYISAM as Innodb storage engine supports foreign keys in Mysql.
Steps to create foreign keys in phpmyadmin:
INDEX
for the column you want to use as foreign key.UPDATE CASCADE specifies that the column will be updated when the referenced column is updated,
DELETE CASCADE specified rows will be deleted when the referenced rows are deleted.
Alternatively, you can also trigger sql query for the same
ALTER TABLE table_name
ADD CONSTRAINT fk_foreign_key_name
FOREIGN KEY (foreign_key_name)
REFERENCES target_table(target_key_name);
It is possible to rename a file and keep the history intact, although it causes the file to be renamed throughout the entire history of the repository. This is probably only for the obsessive git-log-lovers, and has some serious implications, including these:
Now, since you're still with me, you're a probably solo developer renaming a completely isolated file. Let's move a file using filter-tree
!
Assume you're going to move a file old
into a folder dir
and give it the name new
This could be done with git mv old dir/new && git add -u dir/new
, but that breaks history.
Instead:
git filter-branch --tree-filter 'if [ -f old ]; then mkdir dir && mv old dir/new; fi' HEAD
will redo every commit in the branch, executing the command in the ticks for each iteration. Plenty of stuff can go wrong when you do this. I normally test to see if the file is present (otherwise it's not there yet to move) and then perform the necessary steps to shoehorn the tree to my liking. Here you might sed through files to alter references to the file and so on. Knock yourself out! :)
When completed, the file is moved and the log is intact. You feel like a ninja pirate.
Also; The mkdir dir is only necessary if you move the file to a new folder, of course. The if will avoid the creation of this folder earlier in history than your file exists.
From DataTables website:
Each cell in DataTables requests data, and when DataTables tries to obtain data for a cell and is unable to do so, it will trigger a warning, telling you that data is not available where it was expected to be. The warning message is:
DataTables warning: table id=
{id}
- Requested unknown parameter '{parameter}
' for row{row-index}
where:
{id}
is replaced with the DOM id of the table that has triggered the error
{parameter}
is the name of the data parameter DataTables is requesting
{row-index}
is the DataTables internal row index for the rwo that has triggered the error.So to break it down, DataTables has requested data for a given row, of the
{parameter}
provided and there is no data there, or it isnull
orundefined
.
See this tech note on DataTables web site for more information.
You can also left pad with zeros. For example if you want number
to have 9 characters length, left padded with zeros use:
print('{:09.3f}'.format(number))
Thus, if number = 4.656
, the output is: 00004.656
For your example the output will look like this:
numbers = [23.2300, 0.1233, 1.0000, 4.2230, 9887.2000]
for x in numbers:
print('{:010.4f}'.format(x))
prints:
00023.2300
00000.1233
00001.0000
00004.2230
09887.2000
One example where this may be useful is when you want to properly list filenames in alphabetical order. I noticed in some linux systems, the number is: 1,10,11,..2,20,21,...
Thus if you want to enforce the necessary numeric order in filenames, you need to left pad with the appropriate number of zeros.
In Xcode 4.5 and above, this can now be done by using 'Auto-layouting / Constraints'.
Major advantages are that:
A few disadvantages:
Coolest thing is we get to focus on declaring an intent such as:
Here is a simple tutorial to get introduced to auto-layouting.
For a more details.
It takes some time at first, but it sure looks like it will be well worth the effort.
Runtime rt = Runtime.getRuntime();
rt.maxMemory()
value is b
ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
am.getMemoryClass()
value is MB
One way to solve this problem is by turning the warnings off.
SET ANSI_WARNINGS OFF;
GO
You can use git-archive, for example:
git archive master | bzip2 > project.tar.bz2
Where master
is the desired branch.
If we do it just like this:
Dim myArr as Variant
myArr = Range("A1:A10")
the new array will be with two dimensions. Which is not always somehow comfortable to work with:
To get away of the two dimensions, when getting a single column to array, we may use the built-in Excel function “Transpose”. With it, the data becomes in one dimension:
If we have the data in a row, a single transpose will not do the job. We need to use the Transpose function twice:
Note: As you see from the screenshots, when generated this way, arrays start with 1, not with 0. Just be a bit careful.
Great question and great idea, but in SQL you'll need to do this:
For data type datetime, something like this-
declare @BeginDate datetime = '1/1/2016',
@EndDate datetime = '12/1/2016'
create table #months (dates datetime)
declare @var datetime = @BeginDate
while @var < dateadd(MONTH, +1, @EndDate)
Begin
insert into #months Values(@var)
set @var = Dateadd(MONTH, +1, @var)
end
If all you really want is numbers, do this-
create table #numbas (digit int)
declare @var int = 1 --your starting digit
while @var <= 12 --your ending digit
begin
insert into #numbas Values(@var)
set @var = @var +1
end
To send the raw file only:
using(WebClient client = new WebClient()) {
client.UploadFile(address, filePath);
}
If you want to emulate a browser form with an <input type="file"/>
, then that is harder. See this answer for a multipart/form-data answer.
StringBuilder
is faster than StringBuffer
because it's not synchronized
.
Here's a simple benchmark test:
public class Main {
public static void main(String[] args) {
int N = 77777777;
long t;
{
StringBuffer sb = new StringBuffer();
t = System.currentTimeMillis();
for (int i = N; i --> 0 ;) {
sb.append("");
}
System.out.println(System.currentTimeMillis() - t);
}
{
StringBuilder sb = new StringBuilder();
t = System.currentTimeMillis();
for (int i = N; i > 0 ; i--) {
sb.append("");
}
System.out.println(System.currentTimeMillis() - t);
}
}
}
A test run gives the numbers of 2241 ms
for StringBuffer
vs 753 ms
for StringBuilder
.
PASS A HASH INTO THE METHOD AND POPULATE IT......
public void buildResponse(String data, Map response);
We can decorate the items using various decorators attached to the recyclerview such as the DividerItemDecoration:
Simply use the following ...taken from the answer by EyesClear
public class DividerItemDecoration extends RecyclerView.ItemDecoration {
private static final int[] ATTRS = new int[]{android.R.attr.listDivider};
private Drawable mDivider;
/**
* Default divider will be used
*/
public DividerItemDecoration(Context context) {
final TypedArray styledAttributes = context.obtainStyledAttributes(ATTRS);
mDivider = styledAttributes.getDrawable(0);
styledAttributes.recycle();
}
/**
* Custom divider will be used
*/
public DividerItemDecoration(Context context, int resId) {
mDivider = ContextCompat.getDrawable(context, resId);
}
@Override
public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) {
int left = parent.getPaddingLeft();
int right = parent.getWidth() - parent.getPaddingRight();
int childCount = parent.getChildCount();
for (int i = 0; i < childCount; i++) {
View child = parent.getChildAt(i);
RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child.getLayoutParams();
int top = child.getBottom() + params.bottomMargin;
int bottom = top + mDivider.getIntrinsicHeight();
mDivider.setBounds(left, top, right, bottom);
mDivider.draw(c);
}
}
} and then use the above as follows
RecyclerView.ItemDecoration itemDecoration = new DividerItemDecoration(this, DividerItemDecoration.VERTICAL_LIST);
recyclerView.addItemDecoration(itemDecoration);
This will display dividers between each item within the list as shown below:
And for those of who are looking for more details can check out this guide Using the RecyclerView _ CodePath Android Cliffnotes
Some answers here suggest the use of margins but the catch is that : If you add both top and bottom margins, they will appear both added between items and they will be too large. If you only add either, there will be no margin either at the top or the bottom of the whole list. If you add half of the distance at the top, half at the bottom, the outer margins will be too small.
Thus, the only aesthetically correct solution is the divider that the system knows where to apply properly: between items but not above or below items.
Please let me know of any doubts in the comments below :)
In Swift:
Add a flag to test if it's a modal by the class type:
// MARK: - UIViewController implementation
extension UIViewController {
var isModal: Bool {
let presentingIsModal = presentingViewController != nil
let presentingIsNavigation = navigationController?.presentingViewController?.presentedViewController == navigationController
let presentingIsTabBar = tabBarController?.presentingViewController is UITabBarController
return presentingIsModal || presentingIsNavigation || presentingIsTabBar
}
}
BigDecimal b = BigDecimal.valueOf(d);
import java.math.*;
public class Test {
public static void main(String[] args)
{
// Creating a Double Object
Double d = new Double("785.254");
/// Assigning the bigdecimal value of ln to b
BigDecimal b = BigDecimal.valueOf(d);
// Displaying BigDecimal value
System.out.println("The Converted BigDecimal value is: " + b);
}
}
First, a short description of $on()
, $broadcast()
and $emit()
:
.$on(name, listener)
- Listens for a specific event by a given name
.$broadcast(name, args)
- Broadcast an event down through the $scope
of all children.$emit(name, args)
- Emit an event up the $scope
hierarchy to all parents, including the $rootScope
Based on the following HTML (see full example here):
<div ng-controller="Controller1">
<button ng-click="broadcast()">Broadcast 1</button>
<button ng-click="emit()">Emit 1</button>
</div>
<div ng-controller="Controller2">
<button ng-click="broadcast()">Broadcast 2</button>
<button ng-click="emit()">Emit 2</button>
<div ng-controller="Controller3">
<button ng-click="broadcast()">Broadcast 3</button>
<button ng-click="emit()">Emit 3</button>
<br>
<button ng-click="broadcastRoot()">Broadcast Root</button>
<button ng-click="emitRoot()">Emit Root</button>
</div>
</div>
The fired events will traverse the $scopes
as follows:
$scope
$scope
then $rootScope
$scope
then Controller 3 $scope
$scope
then $rootScope
$scope
$scope
, Controller 2 $scope
then $rootScope
$rootScope
and $scope
of all the Controllers (1, 2 then 3) $rootScope
JavaScript to trigger events (again, you can see a working example here):
app.controller('Controller1', ['$scope', '$rootScope', function($scope, $rootScope){
$scope.broadcastAndEmit = function(){
// This will be seen by Controller 1 $scope and all children $scopes
$scope.$broadcast('eventX', {data: '$scope.broadcast'});
// Because this event is fired as an emit (goes up) on the $rootScope,
// only the $rootScope will see it
$rootScope.$emit('eventX', {data: '$rootScope.emit'});
};
$scope.emit = function(){
// Controller 1 $scope, and all parent $scopes (including $rootScope)
// will see this event
$scope.$emit('eventX', {data: '$scope.emit'});
};
$scope.$on('eventX', function(ev, args){
console.log('eventX found on Controller1 $scope');
});
$rootScope.$on('eventX', function(ev, args){
console.log('eventX found on $rootScope');
});
}]);
Why dont you just add a new Partial View with i's own specific controller passing the required model to the partial view and finally Render the mentioned partial view on your Layout.cshtml using RenderPartial or RenderAction ?

to other buttons. Now in the form below you can hit Enter in any input fields, and the Render
button will work (despite the fact it is the second button in the form).
Example:
<button id='close_button' class='btn btn-success'
type=button>
<span class='glyphicon glyphicon-edit'> </span> Edit program
</button>
<button id='render_button' class='btn btn-primary'
type=submit> <!-- Here we use SUBMIT, not BUTTON -->
<span class='glyphicon glyphicon-send'> </span> Render
</button>
Tested in FF24 and Chrome 35.
For capital letters:
i=67
letters=({A..Z})
echo "${letters[$i-65]}"
Output:
C
IMO OP does not actually want np.bitwise_and()
(aka &
) but actually wants np.logical_and()
because they are comparing logical values such as True
and False
- see this SO post on logical vs. bitwise to see the difference.
>>> x = array([5, 2, 3, 1, 4, 5])
>>> y = array(['f','o','o','b','a','r'])
>>> output = y[np.logical_and(x > 1, x < 5)] # desired output is ['o','o','a']
>>> output
array(['o', 'o', 'a'],
dtype='|S1')
And equivalent way to do this is with np.all()
by setting the axis
argument appropriately.
>>> output = y[np.all([x > 1, x < 5], axis=0)] # desired output is ['o','o','a']
>>> output
array(['o', 'o', 'a'],
dtype='|S1')
by the numbers:
>>> %timeit (a < b) & (b < c)
The slowest run took 32.97 times longer than the fastest. This could mean that an intermediate result is being cached.
100000 loops, best of 3: 1.15 µs per loop
>>> %timeit np.logical_and(a < b, b < c)
The slowest run took 32.59 times longer than the fastest. This could mean that an intermediate result is being cached.
1000000 loops, best of 3: 1.17 µs per loop
>>> %timeit np.all([a < b, b < c], 0)
The slowest run took 67.47 times longer than the fastest. This could mean that an intermediate result is being cached.
100000 loops, best of 3: 5.06 µs per loop
so using np.all()
is slower, but &
and logical_and
are about the same.
Using the form you already have:
var input = document.querySelector('form[name=myForm] #username');
input.onkeyup = function() {
var patterns = /[^0-9]/g;
var caretPos = this.selectionStart;
this.value = input.value.replace(patterns, '');
this.setSelectionRange(caretPos, caretPos);
}
This will delete all non-digits after the key is released.
If we have this variables:
var counter int = 5
var message string = "Hello"
var factor float32 = 4.2
var enabled bool = false
1: fmt.Printf %T format : to use this feature you should import "fmt"
fmt.Printf("%T \n",factor ) // factor type: float32
2: reflect.TypeOf function : to use this feature you should import "reflect"
fmt.Println(reflect.TypeOf(enabled)) // enabled type: bool
3: reflect.ValueOf(X).Kind() : to use this feature you should import "reflect"
fmt.Println(reflect.ValueOf(counter).Kind()) // counter type: int
Check App is installed or not in Android by using kotlin.
Creating kotlin extension.
fun PackageManager.isAppInstalled(packageName: String): Boolean = try {
getApplicationInfo(packageName, PackageManager.GET_META_DATA)
true
} catch (e: Exception) {
false
}
Now, can check if app is install or not
if (packageManager.isAppInstalled("AppPackageName")) {
// App is installed
}else{
// App is not installed
}
@RequestParam
annotation tells Spring that it should map a request parameter from the GET/POST request to your method argument. For example:
request:
GET: http://someserver.org/path?name=John&surname=Smith
endpoint code:
public User getUser(@RequestParam(value = "name") String name,
@RequestParam(value = "surname") String surname){
...
}
So basically, while @RequestBody
maps entire user request (even for POST) to a String variable, @RequestParam
does so with one (or more - but it is more complicated) request param to your method argument.
I have found the browser referer implementation to be really inconsistent.
For example, an anchor element with the "download" attribute works as expected in Safari and sends the referer, but in Chrome the referer will be empty or "-" in the web server logs.
<a href="http://foo.com/foo" download="bar">click to download</a>
Is broken in Chrome - no referer sent.
For a JQM+PhoneGap app the following worked for me.
The following was the minimum I had to go to get this to work. I was actually experiencing a stall due to the buffering while spawning ajax requests when the user pressed the back button. Pausing the video in Chrome and the Android browser kept it buffering. The non-async ajax request would get stuck waiting for the buffering to finish, which it never would.
Binding this to the beforepagehide event fixed it.
$("#SOME_JQM_PAGE").live("pagebeforehide", function(event)
{
$("video").each(function ()
{
logger.debug("PAUSE VIDEO");
this.pause();
this.src = "";
});
});
This will clear every video tag on the page.
The important part is this.src = "";
Under HTML5 you are be able to do this:
document.getElementById('test').selectedOptions[0].text
MDN's documentation at https://developer.mozilla.org/en-US/docs/Web/API/HTMLSelectElement/selectedOptions indicates full cross-browser support (as of at least December 2017), including Chrome, Firefox, Edge and mobile browsers, but excluding Internet Explorer.
Above solutions seem to assume integers. Here's a minor modification to allow decimals:
num = float("".join(filter(lambda d: str.isdigit(d) or d == '.', inputString)
(Doesn't account for - sign, and assumes any period is properly placed in digit string, not just some english-language period lying around. It's not built to be indestructible, but worked for my data case.)
git branch --merged | grep -E -v "(master|test|dev)" | xargs git branch -d
where grep -E -v
is equivalent of egrep -v
Use -d
to remove already merged branches or
-D
to remove unmerged branches
Use boost::filesystem:
#include <boost/filesystem.hpp>
if ( !boost::filesystem::exists( "myfile.txt" ) )
{
std::cout << "Can't find my file!" << std::endl;
}
Try:
require(Hmisc)
sapply(name, function(x) {
paste(sapply(strsplit(x, ' '), capitalize), collapse=' ')
})
Byte is not a standard data type in C/C++ but it can still be used the way i suppose you want it. Here is how: Recall that a byte is an eight bit memory size which can represent any of the integers between -128 and 127, inclusive. (There are 256 integers in that range; eight bits can represent 256 -- two raised to the power eight -- different values.). Also recall that a char in C/C++ is one byte (eight bits). So, all you need to do to have a byte data type in C/C++ is to put this code at the top of your source file: #define byte char So you can now declare byte abc[3];
std::string
is the C++ equivalent: It's mutable.
Both T1
and T2
can refer to a class containing this variable.
You can then make this variable volatile, and this means that
Changes to that variable are immediately visible in both threads.
See this article for more info.
Volatile variables share the visibility features of synchronized but none of the atomicity features. This means that threads will automatically see the most up-to-date value for volatile variables. They can be used to provide thread safety, but only in a very restricted set of cases: those that do not impose constraints between multiple variables or between a variable's current value and its future values.
And note the pros/cons of using volatile
vs more complex means of sharing state.
It would be more useful to have a full function for real-world usage of truncating a decimal in C#. This could be converted to a Decimal extension method pretty easy if you wanted:
public decimal TruncateDecimal(decimal value, int precision)
{
decimal step = (decimal)Math.Pow(10, precision);
decimal tmp = Math.Truncate(step * value);
return tmp / step;
}
If you need VB.NET try this:
Function TruncateDecimal(value As Decimal, precision As Integer) As Decimal
Dim stepper As Decimal = Math.Pow(10, precision)
Dim tmp As Decimal = Math.Truncate(stepper * value)
Return tmp / stepper
End Function
Then use it like so:
decimal result = TruncateDecimal(0.275, 2);
or
Dim result As Decimal = TruncateDecimal(0.275, 2)

I'm afraid none of these solutions worked for me. Perhaps because I was using belongs_to
in my create_table migration for a polymorphic association.
I'll add my code below and a link to the solution that helped me in case anyone else stumbles upon when searching for 'Index name is too long' in connection with polymorphic associations.
The following code did NOT work for me:
def change
create_table :item_references do |t|
t.text :item_unique_id
t.belongs_to :referenceable, polymorphic: true
t.timestamps
end
add_index :item_references, [:referenceable_id, :referenceable_type], name: 'idx_item_refs'
end
This code DID work for me:
def change
create_table :item_references do |t|
t.text :item_unique_id
t.belongs_to :referenceable, polymorphic: true, index: { name: 'idx_item_refs' }
t.timestamps
end
end
This is the SO Q&A that helped me out: https://stackoverflow.com/a/30366460/3258059
To parse a Date from a String you can choose which format you would like it to have. For example:
public Date StringToDate(String s){
Date result = null;
try{
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
result = dateFormat.parse(s);
}
catch(ParseException e){
e.printStackTrace();
}
return result ;
}
If you would like to use this method now, you will have to use something like this
Date date = StringToDate("2015-12-06 17:03:00");
For more explanation you should check out http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
Debug and Release are just labels for different solution configurations. You can add others if you want. A project I once worked on had one called "Debug Internal" which was used to turn on the in-house editing features of the application. You can see this if you go to Configuration Manager...
(it's on the Build
menu). You can find more information on MSDN Library under Configuration Manager Dialog Box.
Each solution configuration then consists of a bunch of project configurations. Again, these are just labels, this time for a collection of settings for your project. For example, our C++ library projects have project configurations called "Debug", "Debug_Unicode", "Debug_MT", etc.
The available settings depend on what type of project you're building. For a .NET project, it's a fairly small set: #define
s and a few other things. For a C++ project, you get a much bigger variety of things to tweak.
In general, though, you'll use "Debug" when you want your project to be built with the optimiser turned off, and when you want full debugging/symbol information included in your build (in the .PDB file, usually). You'll use "Release" when you want the optimiser turned on, and when you don't want full debugging information included.

var evObj = document.createEvent('Events');
evObj.initEvent(etype, true, false);
el.dispatchEvent(evObj);
}
}

eventFire(document.getElementById('picToClick'), 'click');

You can detect end of the list with help of onScrollListener, working code is presented below:
@Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
if (view.getAdapter() != null && ((firstVisibleItem + visibleItemCount) >= totalItemCount) && totalItemCount != mPrevTotalItemCount) {
Log.v(TAG, "onListEnd, extending list");
mPrevTotalItemCount = totalItemCount;
mAdapter.addMoreData();
}
}
Another way to do that (inside adapter) is as following:
public View getView(int pos, View v, ViewGroup p) {
if(pos==getCount()-1){
addMoreData(); //should be asynctask or thread
}
return view;
}
Be aware that this method will be called many times, so you need to add another condition to block multiple calls of addMoreData()
.
When you add all elements to the list, please call notifyDataSetChanged() inside yours adapter to update the View (it should be run on UI thread - runOnUiThread)
Agree with neubert about the DECLARE statements, this will fix syntax error. But I would suggest you to avoid using openning cursors, they may be slow.
For your task: use INSERT...SELECT statement which will help you to copy data from one table to another using only one query.
Of course that works; when @item1 = N''
, it IS NOT NULL
.
You can define @item1
as NULL
by default at the top of your stored procedure, and then not pass in a parameter.

In Python 3.x the raw_input()
of Python 2.x has been replaced by input()
function. However in both the cases you cannot input multi-line strings, for that purpose you would need to get input from the user line by line and then .join()
them using \n
, or you can also take various lines and concatenate them using +
operator separated by \n
To get multi-line input from the user you can go like:
no_of_lines = 5
lines = ""
for i in xrange(no_of_lines):
lines+=input()+"\n"
print(lines)
Or
lines = []
while True:
line = input()
if line:
lines.append(line)
else:
break
text = '\n'.join(lines)
Hopefully it's helpful for you:
.text-with-dots {_x000D_
display: block;_x000D_
max-width: 98%;_x000D_
white-space: nowrap;_x000D_
overflow: hidden !important;_x000D_
text-overflow: ellipsis;_x000D_
}

A static method relates an action to a type of object, whereas the non static method relates an action to an instance of that type of object. Typically it is a method that does something with relation to the instance.
Ex:
class Car might have a wash method, which would indicate washing a particular car, whereas a static method would apply to the type car.
Mootools solution:
new Date(Date(result.AppendDts)).format('%x')
Requires mootools-more. Tested using mootools-1.2.3.1-more on Firefox 3.6.3 and IE 7.0.5730.13
Just set the property of textbox that is
PasswordChar and set the *
as a property
of textbox. That will work for password.
passwordtextbox.PasswordChar = '*';
where passwordtextbox
is the text box name.
And another expansion:
# create dummy matrix
set.seed(10)
m <- matrix(round(runif(25, 1, 5)), 5)
d <- as.data.frame(m)
If you want to assign new column names you can do following on data.frame
:
# an identical effect can be achieved with colnames()
names(d) <- LETTERS[1:5]
> d
A B C D E
1 3 2 4 3 4
2 2 2 3 1 3
3 3 2 1 2 4
4 4 3 3 3 2
5 1 3 2 4 3
If you, however run previous command on matrix
, you'll mess things up:
names(m) <- LETTERS[1:5]
> m
[,1] [,2] [,3] [,4] [,5]
[1,] 3 2 4 3 4
[2,] 2 2 3 1 3
[3,] 3 2 1 2 4
[4,] 4 3 3 3 2
[5,] 1 3 2 4 3
attr(,"names")
[1] "A" "B" "C" "D" "E" NA NA NA NA NA NA NA NA NA NA NA NA NA NA
[20] NA NA NA NA NA NA
Since matrix can be regarded as two-dimensional vector, you'll assign names only to first five values (you don't want to do that, do you?). In this case, you should stick with colnames()
.
So there...

Via JavaScript Call the dropdowns via JavaScript:
Paste this is code after bootstrap.min.js
$('.dropdown-toggle').dropdown();
Also, make sure you include popper.min.js before bootstrap.min.js
Dropdowns are positioned thanks to Popper.js (except when they are contained in a navbar).
Python added the @overload decorator with PEP-3124 to provide syntactic sugar for overloading via type inspection - instead of just working with overwriting.
Code example on overloading via @overload from PEP-3124
from overloading import overload
from collections import Iterable
def flatten(ob):
"""Flatten an object to its component iterables"""
yield ob
@overload
def flatten(ob: Iterable):
for o in ob:
for ob in flatten(o):
yield ob
@overload
def flatten(ob: basestring):
yield ob
is transformed by the @overload-decorator to:
def flatten(ob):
if isinstance(ob, basestring) or not isinstance(ob, Iterable):
yield ob
else:
for o in ob:
for ob in flatten(o):
yield ob
Here is an immutable (does not modify the inputs) version of @Salakar's answer. Useful if you're doing functional programming type stuff.

Object.assign(output, { [key]: source[key] });
else
output[key] = mergeDeep(target[key], source[key]);

I know its 3 years too late, but maybe it can help someone else because I haven't found anything like that except for the moment-timezone library, which is not exactly the same as what he's asking for here.
I've done something similar for german timezone, this is a little complex because of daylight saving time and leap years where you have 366 days.
it might need a little work with the "isDaylightSavingTimeInGermany" function while different timezones change on different times the daylight saving time.
anyway, check out this page: https://github.com/zerkotin/german-timezone-converter/wiki
the main methods are: convertLocalDateToGermanTimezone convertGermanDateToLocalTimezone
I've put an effort into documenting it, so it won't be so confusing.
I wrote an EnumUtil class which is making a type check by the enum value:
export class EnumUtils {
/**
* Returns the enum keys
* @param enumObj enum object
* @param enumType the enum type
*/
static getEnumKeys(enumObj: any, enumType: EnumType): any[] {
return EnumUtils.getEnumValues(enumObj, enumType).map(value => enumObj[value]);
}
/**
* Returns the enum values
* @param enumObj enum object
* @param enumType the enum type
*/
static getEnumValues(enumObj: any, enumType: EnumType): any[] {
return Object.keys(enumObj).filter(key => typeof enumObj[key] === enumType);
}
}
export enum EnumType {
Number = 'number',
String = 'string'
}
How to use it:
enum NumberValueEnum{
A= 0,
B= 1
}
enum StringValueEnum{
A= 'A',
B= 'B'
}
EnumUtils.getEnumKeys(NumberValueEnum, EnumType.Number);
EnumUtils.getEnumValues(NumberValueEnum, EnumType.Number);
EnumUtils.getEnumKeys(StringValueEnum, EnumType.String);
EnumUtils.getEnumValues(StringValueEnum, EnumType.String);
Result for NumberValueEnum keys: ["A", "B"]
Result for NumberValueEnum values: [0, 1]
Result for StringValueEnumkeys: ["A", "B"]
Result for StringValueEnumvalues: ["A", "B"]
You could also use the great laravel-cors package by barryvdh.
After you have the package installed, the easiest way to get CORS support for all your routes is to add the middleware like this in Http/Kernel.php:
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
\Barryvdh\Cors\HandleCors::class,
];
If you dont want to have CORS support on all your routes you should make a new OPTIONS route for /oauth/token
and add the cors middleware to that route only.
Edit for Laravel 8
Laravel 8 already has CORS Support built in - HandleCors
middleware is defined in your global middleware stack by default and can be configured in your application's config/cors.php
config file.
If you update your Laravel application be sure to change out barryvdh's package with the supplied middleware: \Fruitcake\Cors\HandleCors::class
I had this issue, and solved. This was due to the WHERE clause contains String value instead of integer value.
The approach I would take is: when reading the chapters from the database, instead of a collection of chapters, use a collection of books. This will have your chapters organised into books and you'll be able to use information from both classes to present the information to the user (you can even present it in a hierarchical way easily when using this approach).
It will help you a lot Basic Git Commands
One more approach to reading a file that I happen to like is referred to variously as variable notation or variable syntax and involves simply enclosing a filespec within curly braces preceded by a dollar sign, to wit:
$content = ${C:file.txt}
This notation may be used as either an L-value or an R-value; thus, you could just as easily write to a file with something like this:
${D:\path\to\file.txt} = $content
Another handy use is that you can modify a file in place without a temporary file and without sub-expressions, for example:
${C:file.txt} = ${C:file.txt} | select -skip 1
I became fascinated by this notation initially because it was very difficult to find out anything about it! Even the PowerShell 2.0 specification mentions it only once showing just one line using it--but with no explanation or details of use at all. I have subsequently found this blog entry on PowerShell variables that gives some good insights.
One final note on using this: you must use a drive designation, i.e. ${drive:filespec}
as I have done in all the examples above. Without the drive (e.g. ${file.txt}
) it does not work. No restrictions on the filespec on that drive: it may be absolute or relative.
I think a short example of where you would use .
and not $
would help clarify things.
double x = x * 2
triple x = x * 3
times6 = double . triple
:i times6
times6 :: Num c => c -> c
Note that times6
is a function that is created from function composition.
If you want the previous year and month relative to a specific date and have DateTime available then you can do this:
$d = new DateTime('2013-01-01', new DateTimeZone('UTC'));
$d->modify('first day of previous month');
$year = $d->format('Y'); //2012
$month = $d->format('m'); //12
Apparently anonymous functions cannot be serialized.
Example
$function = function () {
return "ABC";
};
serialize($function); // would throw error
From your code you are using Closure:
$callback = function () // <---------------------- Issue
{
return 'ZendMail_' . microtime(true) . '.tmp';
};
Solution 1 : Replace with a normal function
Example
function emailCallback() {
return 'ZendMail_' . microtime(true) . '.tmp';
}
$callback = "emailCallback" ;
Solution 2 : Indirect method call by array variable
If you look at http://docs.mnkras.com/libraries_23rdparty_2_zend_2_mail_2_transport_2file_8php_source.html
public function __construct($options = null)
63 {
64 if ($options instanceof Zend_Config) {
65 $options = $options->toArray();
66 } elseif (!is_array($options)) {
67 $options = array();
68 }
69
70 // Making sure we have some defaults to work with
71 if (!isset($options['path'])) {
72 $options['path'] = sys_get_temp_dir();
73 }
74 if (!isset($options['callback'])) {
75 $options['callback'] = array($this, 'defaultCallback'); <- here
76 }
77
78 $this->setOptions($options);
79 }
You can use the same approach to send the callback
$callback = array($this,"aMethodInYourClass");
When I stumbled up on this answer I was looking for a way to get an output that is easy to parse. For me the option --with-colons
did the trick:

queries. They serve this exact purpose. Here's an example how they work:
@media (max-width: 800px) {
/* CSS that should be displayed if width is equal to or less than 800px goes here */
}
This would work only on devices whose width is equal to or less than 800px.
Read up more about media queries on the Mozilla Developer Network.
So I had a lot of problems with all of the solutions mentioned so far...
I have a local package that I want to always reference (rather than npm link) because it won't be used outside of this project (for now) and also won't be uploaded to an npm repository for wide use as of yet.
I also need it to work on Windows AND Unix, so sym-links aren't ideal.
Pointing to the tar.gz result of (npm package) works for the dependent npm package folder, however this causes issues with the npm cache if you want to update the package. It doesn't always pull in the new one from the referenced npm package when you update it, even if you blow away node_modules and re-do your npm-install for your main project.
so.. This is what worked well for me!
Main Project's Package.json File Snippet:
"name": "main-project-name",
"version": "0.0.0",
"scripts": {
"ng": "ng",
...
"preinstall": "cd ../some-npm-package-angular && npm install && npm run build"
},
"private": true,
"dependencies": {
...
"@com/some-npm-package-angular": "file:../some-npm-package-angular/dist",
...
}
This achieves 3 things:
I hope this is clear, and helps someone out.
The tar.gz approach also sort of works..
npm install (file path) also sort of works.
This was all based off of a generated client from an openapi spec that we wanted to keep in a separate location (rather than using copy-pasta for individual files)
====== UPDATE: ======
There are additional errors with a regular development flow with the above solution, as npm's versioning scheme with local files is absolutely terrible. If your dependent package changes frequently, this whole scheme breaks because npm will cache your last version of the project and then blow up when the SHA hash doesn't match anymore with what was saved in your package-lock.json file, among other issues.
As a result, I recommend using the *.tgz approach with a version update for each change. This works by doing three things.
First:
For your dependent package, use the npm library "ng-packagr". This is automatically added to auto-generated client packages created by the angular-typescript code generator for OpenAPI 3.0.
As a result the project that I'm referencing has a "scripts" section within package.json that looks like this:
"scripts": {
"build": "ng-packagr -p ng-package.json",
"package": "npm install && npm run build && cd dist && npm pack"
},
And the project referencing this other project adds a pre-install step to make sure the dependent project is up to date and rebuilt before building itself:
"scripts": {
"preinstall": "npm run clean && cd ../some-npm-package-angular && npm run package"
},
Second
Reference the built tgz npm package from your main project!
"dependencies": {
"@com/some-npm-package-angular": "file:../some-npm-package-angular/dist/some-npm-package-angular-<packageVersion>.tgz",
...
}
Third
Update the dependent package's version EVERY TIME you update the dependent package. You'll also have to update the version in the main project.
If you do not do this, NPM will choke and use a cached version and explode when the SHA hash doesn't match. NPM versions file-based packages based on the filename changing. It won't check the package itself for an updated version in package.json, and the NPM team stated that they will not fix this, but people keep raising the issue: https://github.com/microsoft/WSL/issues/348
for now, just update the:
"version": "1.0.0-build5",
In the dependent package's package.json file, then update your reference to it in the main project to reference the new filename, ex:
"dependencies": {
"@com/some-npm-package-angular": "file:../some-npm-package-angular/dist/some-npm-package-angular-1.0.0-build5.tgz",
...
}
You get used to it. Just update the two package.json files - version then the ref to the new filename.
Hope that helps someone...
Hi , You can use this in your .ts file :
first import your service in this .ts file:
import { Your_Service_Name } from './path_To_Your_Service_Name';
Then in the same file you can add providers: [Your_Service_Name]
:
@Component({
selector: 'my-app',
providers: [Your_Service_Name],
template: `
<h1>Hello World</h1> `
})
You can use iCheck. It is customized checkboxes and radio buttons for jQuery & Zepto, and maybe it will help you.
Make sure jQuery v1.7+ is loaded before the icheck.js
Insert before in your HTML (replace your-path and color-scheme):
<link href="your-path/minimal/color-scheme.css" rel="stylesheet">
<script src="your-path/icheck.js"></script>
Example for a Red color scheme:
<link href="your-path/minimal/red.css" rel="stylesheet">
<script src="your-path/icheck.js"></script>
Add some checkboxes and radio buttons to your HTML:
<input type="checkbox">
<input type="checkbox" checked>
<input type="radio" name="iCheck">
<input type="radio" name="iCheck" checked>
Add JavaScript to your HTML to launch iCheck plugin:
<script>
$(document).ready(function(){
$('input').iCheck({
checkboxClass: 'icheckbox_minimal',
radioClass: 'iradio_minimal',
increaseArea: '20%' // Optional
});
});
</script>
For different from black color schemes use this code (example for Red):
<script>
$(document).ready(function(){
$('input').iCheck({
checkboxClass: 'icheckbox_minimal-red',
radioClass: 'iradio_minimal-red',
increaseArea: '20%' // Optional
});
});
</script>
Done
Well, all of these approaches are interesting, however as lazy programmer I use yank all line by using combination of number + y
for example you have source code file with total of 78 lines, you can do as below:
gg
to get cursor at first line y
--> it yanks 78 lines below your cursor and current line Here is a function to do what you want. It should take care of degenerate cases where the string is all whitespace. You must pass in an output buffer and the length of the buffer, which means that you have to pass in a buffer that you allocate.
void str_trim(char *output, const char *text, int32 max_len)
{
int32 i, j, length;
length = strlen(text);
if (max_len < 0) {
max_len = length + 1;
}
for (i=0; i<length; i++) {
if ( (text[i] != ' ') && (text[i] != '\t') && (text[i] != '\n') && (text[i] != '\r')) {
break;
}
}
if (i == length) {
// handle lines that are all whitespace
output[0] = 0;
return;
}
for (j=length-1; j>=0; j--) {
if ( (text[j] != ' ') && (text[j] != '\t') && (text[j] != '\n') && (text[j] != '\r')) {
break;
}
}
length = j + 1 - i;
strncpy(output, text + i, length);
output[length] = 0;
}
The if statements in the loops can probably be replaced with isspace(text[i]) or isspace(text[j]) to make the lines a little easier to read. I think that I had them set this way because there were some characters that I didn't want to test for, but it looks like I'm covering all whitespace now :-)
I also had the error message "TypeError: cannot concatenate 'str' and 'int' objects". It turns out that I only just forgot to add str() around a variable when printing it. Here is my code:
def main():_x000D_
rolling = True; import random_x000D_
while rolling:_x000D_
roll = input("ENTER = roll; Q = quit ")_x000D_
if roll.lower() != 'q':_x000D_
num = (random.randint(1,6))_x000D_
print("----------------------"); print("you rolled " + str(num))_x000D_
else:_x000D_
rolling = False_x000D_
main()
_x000D_
I know, it was a stupid mistake but for beginners who are very new to python such as myself, it happens.
You can do it like this:
In your main view controller:
func showModal() {
let modalViewController = ModalViewController()
modalViewController.modalPresentationStyle = .overCurrentContext
presentViewController(modalViewController, animated: true, completion: nil)
}
In your modal view controller:
class ModalViewController: UIViewController {
override func viewDidLoad() {
view.backgroundColor = UIColor.clearColor()
view.opaque = false
}
}
If you are working with a storyboard:
Just add a Storyboard Segue with Kind
set to Present Modally
to your modal view controller and on this view controller set the following values:
As Crashalot pointed out in his comment: Make sure the segue only uses Default
for both Presentation
and Transition
. Using Current Context
for Presentation
makes the modal turn black instead of remaining transparent.
A single star means that the variable 'a' will be a tuple of extra parameters that were supplied to the function. The double star means the variable 'kw' will be a variable-size dictionary of extra parameters that were supplied with keywords.
Although the actual behavior is spec'd out, it still sometimes can be very non-intuitive. Writing some sample functions and calling them with various parameter styles may help you understand what is allowed and what the results are.
def f0(a)
def f1(*a)
def f2(**a)
def f3(*a, **b)
etc...
It appears that SSRS has an issue(at leastin version 2008) - I'm studying this website that explains it
Where it says if you have two columns(from 2 diff. tables) with the same name, then it'll cause that problem.
From source:
SELECT a.Field1, a.Field2, a.Field3, b.Field1, b.field99 FROM TableA a JOIN TableB b on a.Field1 = b.Field1
SQL handled it just fine, since I had prefixed each with an alias (table) name. But SSRS uses only the column name as the key, not table + column, so it was choking.
The fix was easy, either rename the second column, i.e. b.Field1 AS Field01 or just omit the field all together, which is what I did.
In MySQL if You don't want to change the collation and want to perform case sensitive search then just use binary keyword like this:
SELECT * FROM table_name WHERE binary username=@search_parameter and binary password=@search_parameter
With regards to @CrazyJugglerDrummer second method it would be:
elementsToChange.style.cursor = "http://wiki-devel.sugarlabs.org/images/e/e2/Arrow.cur";
I was curious to see the results of the methods provided in the question as well as the accepted answer, so I put it to the test.
Here's the code:

Console.WriteLine("Worker {0} started on thread {1}, beginning {2} seconds after test start.",
Id, Thread.CurrentThread.ManagedThreadId, (workerStart-testStart).TotalSeconds.ToString("F2"));
await Task.Run(() => Thread.Sleep(SleepTimeout));
var workerEnd = DateTime.Now;
Console.WriteLine("Worker {0} stopped; the worker took {1} seconds, and it finished {2} seconds after the test start.",

Your syntax is pretty screwy.
Change this:
input:not(disabled)not:[type="submit"]:focus{
to:
input:not(:disabled):not([type="submit"]):focus{
Seems that many people don't realize :enabled
and :disabled
are valid CSS selectors...
For ng9 upgraders:

Building on @miklov-kriven's very helpful answer, I hope these two additional points of consideration prove helpful to someone:
(1) I find it a nice idea to include serializer and de-serializer as static inner classes in the same class. NB, using ThreadLocal for thread safety of SimpleDateFormat.
public class DateConverter {
private static final ThreadLocal<SimpleDateFormat> sdf =
ThreadLocal.<SimpleDateFormat>withInitial(
() -> {return new SimpleDateFormat("yyyy-MM-dd HH:mm a z");});
public static class Serialize extends JsonSerializer<Date> {
@Override
public void serialize(Date value, JsonGenerator jgen SerializerProvider provider) throws Exception {
if (value == null) {
jgen.writeNull();
}
else {
jgen.writeString(sdf.get().format(value));
}
}
}
public static class Deserialize extends JsonDeserializer<Date> {
@Overrride
public Date deserialize(JsonParser jp, DeserializationContext ctxt) throws Exception {
String dateAsString = jp.getText();
try {
if (Strings.isNullOrEmpty(dateAsString)) {
return null;
}
else {
return new Date(sdf.get().parse(dateAsString).getTime());
}
}
catch (ParseException pe) {
throw new RuntimeException(pe);
}
}
}
}
(2) As an alternative to using @JsonSerialize and @JsonDeserialize annotations on each individual class member you could also consider overriding Jackson's default serialization by applying the custom serialization at an application level, that is all class members of type Date will be serialized by Jackson using this custom serialization without explicit annotation on each field. If you are using Spring Boot for example one way to do this would as follows:
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Bean
public Module customModule() {
SimpleModule module = new SimpleModule();
module.addSerializer(Date.class, new DateConverter.Serialize());
module.addDeserializer(Date.class, new Dateconverter.Deserialize());
return module;
}
}
No need for external libs to bloat things - especially when working with Android. Here is a native solution that does the trick. This is a pice of code from an app that stores a byte array as an image file.
// Byte array with image data.
final byte[] imageData = params[0];
// Write bytes to tmp file.
final File tmpImageFile = new File(ApplicationContext.getInstance().getCacheDir(), "scan.jpg");
FileOutputStream tmpOutputStream = null;
try {
tmpOutputStream = new FileOutputStream(tmpImageFile);
tmpOutputStream.write(imageData);
Log.d(TAG, "File successfully written to tmp file");
}
catch (FileNotFoundException e) {
Log.e(TAG, "FileNotFoundException: " + e);
return null;
}
catch (IOException e) {
Log.e(TAG, "IOException: " + e);
return null;
}
finally {
if(tmpOutputStream != null)
try {
tmpOutputStream.close();
} catch (IOException e) {
Log.e(TAG, "IOException: " + e);
}
}
option 2 is a bad idea. It will result in something called shadowing; Basically you have two different "MyInt" members, one in the mother, and the other in the daughter. The problem with this, is that methods that are implemented in the mother will reference the mother's "MyInt" while methods implemented in the daughter will reference the daughter's "MyInt". this can cause some serious readability issues, and confusion later down the line.
Personally, I think the best option is 3; because it provides a clear centralized value, and can be referenced internally by children without the hassle of defining their own fields -- which is the problem with option 1.
Geany has an option in its menus that says 'Apply Default Intendation' which replaces tabs by the number of spaces if specified in Geany's settings
The error may be that you need to change the permission of folder and file which you are going to access. If like GoDaddy service you can access the file and change the permission or by ssh use the command like:
sudo chmod 777 file.jpeg
and then you can access if the above mentioned problems are not your case.
Use $elemMatch to find the array of particular object
db.users.findOne({"_id": id},{awards: {$elemMatch: {award:'Turing Award', year:1977}}})
If you're working with "real" data for which the grid intervals and sequence cannot be guaranteed to be increasing or unique (hopefully the (x,y,z)
combinations are unique at least, even if these triples are duplicated), I would recommend the akima
package for interpolating from an irregular grid to a regular one.
Using your definition of data
:
library(akima)
im <- with(data,interp(x,y,z))
with(im,image(x,y,z))
And this should work not only with image
but similar functions as well.
Note that the default grid to which your data is mapped to by akima::interp
is defined by 40 equal intervals spanning the range of x
and y
values:
> formals(akima::interp)[c("xo","yo")]
$xo
seq(min(x), max(x), length = 40)
$yo
seq(min(y), max(y), length = 40)
But of course, this can be overridden by passing arguments xo
and yo
to akima::interp
.
//%%%%%%%%%%%%%%%%%%%%%% HEX to ASCII %%%%%%%%%%%%%%%%%%%%%%
public String convertHexToString(String hex){

if(rmd==1)
hex = "0"+hex;
// split into two characters
for( int i=0; i<hex.length()-1; i+=2 ){
//split the hex into pairs
String pair = hex.substring(i, (i + 2));
//convert hex to decimal
int dec = Integer.parseInt(pair, 16);

Below is a class that can be used in Windows environment, requires ActivePython. You can also inherit for other logging handlers (StreamHandler etc.)
class SyncronizedFileHandler(logging.FileHandler):
MUTEX_NAME = 'logging_mutex'
def __init__(self , *args , **kwargs):
self.mutex = win32event.CreateMutex(None , False , self.MUTEX_NAME)
return super(SyncronizedFileHandler , self ).__init__(*args , **kwargs)
def emit(self, *args , **kwargs):
try:
win32event.WaitForSingleObject(self.mutex , win32event.INFINITE)
ret = super(SyncronizedFileHandler , self ).emit(*args , **kwargs)
finally:
win32event.ReleaseMutex(self.mutex)
return ret
And here is an example that demonstrates usage:
import logging
import random , time , os , sys , datetime
from string import letters
import win32api , win32event
from multiprocessing import Pool
def f(i):
time.sleep(random.randint(0,10) * 0.1)
ch = random.choice(letters)
logging.info( ch * 30)
def init_logging():
'''
initilize the loggers
'''
formatter = logging.Formatter("%(levelname)s - %(process)d - %(asctime)s - %(filename)s - %(lineno)d - %(message)s")
logger = logging.getLogger()
logger.setLevel(logging.INFO)
file_handler = SyncronizedFileHandler(sys.argv[1])
file_handler.setLevel(logging.INFO)
file_handler.setFormatter(formatter)
logger.addHandler(file_handler)
#must be called in the parent and in every worker process
init_logging()
if __name__ == '__main__':
#multiprocessing stuff
pool = Pool(processes=10)
imap_result = pool.imap(f , range(30))
for i , _ in enumerate(imap_result):
pass
Also, name it divrat.m
, not divrat.M
. This shouldn't matter on most OSes, but who knows...
You can also test whether matlab can find a function by using the which
command, i.e.
which divrat
you can use the following code for getting the brand name and brand model of the device.
String brand = Build.BRAND; // for getting BrandName
String model = Build.MODEL; // for getting Model of the device

The string has a substring method that returns the string at the specified position.
String name="123456789";
System.out.println(name.substring(0,1));
Many mobile devices have resolutions so high that it's hard to distinguish between them and much larger screens. There are two ways to deal with this problem:
Use the following HTML code to scale the pixels (grouping smaller pixels into groups the size of the unit pixel - 96dpi, so px
units will have the same physical size on all screens). Note that this will affect the scale of pretty much everything in your website, but this is generally the way to go when making sites mobile-friendly.
<meta name="viewport" content="width=device-width, initial-scale=1">
Alternatively, measuring the screen width in @media
queries using cm
instead of px
units can tell you if you're dealing with a physically small screen regardless of resolution.
If using Visual Studio 2010 you can right-click on the project for the service, and select properties
. Then select the Web
tab. Under the Servers
section you can configure the URL. There is also a button to create the virtual directory.
You can install "Extended Read Permission" plug-in. Then in either "Global Settings" or in individual job configuration, you can give the user "Extended Read" permission.
You should find it in :
C:\Users\User Name\AppData\Local\Android\sdk\platform-tools
Add that to path, or change directory to there. The command sqlite3
is also there.
In the terminal you can type commands like
adb logcat //for logs
adb shell // for android shell
Complementary to this answer from the maximum number of columns (fixed with numpy.set_printoptions(threshold=numpy.nan)
), there is also a limit of characters to be displayed. In some environments like when calling python from bash (rather than the interactive session), this can be fixed by setting the parameter linewidth
as following.
import numpy as np
np.set_printoptions(linewidth=2000) # default = 75
Mat = np.arange(20000,20150).reshape(2,75) # 150 elements (75 columns)
print(Mat)
In this case, your window should limit the number of characters to wrap the line.
For those out there using sublime text and wanting to see results within the output window, you should add the build option "word_wrap": false
to the sublime-build file [source] .
For the follow-up question, you can get a number between 36^5 and 36^6 and convert it in base 36
UPDATED:
using this code
http://javaconfessions.com/2008/09/convert-between-base-10-and-base-62-in_28.html
It's written
BaseConverterUtil.toBase36(60466176+r.nextInt(2116316160))
but in your use case, it can be optimized by using a StringBuilder
and having the number in the reverse order ie 71 should be converted in Z1 instead of 1Z
EDITED:
If this still isn't working try unchecking "Enable Protected Mode" in IE.
Add your site to Local Intranet in
Tools -> Internet Option -> Security Tab
Then uncheck "Enable Protected Mode"
Restart IE
something like this:
public int PowerRating
{
get { return base.PowerRating; } // if power inherits from meter...
}
@DanielChapman gives a good explanation of serialVersionUID, but no solution. the solution is this: run the serialver
program on all your old classes. put these serialVersionUID
values in your current versions of the classes. as long as the current classes are serial compatible with the old versions, you should be fine. (note for future code: you should always have a serialVersionUID
on all Serializable
classes)
if the new versions are not serial compatible, then you need to do some magic with a custom readObject
implementation (you would only need a custom writeObject
if you were trying to write new class data which would be compatible with old code). generally speaking adding or removing class fields does not make a class serial incompatible. changing the type of existing fields usually will.
Of course, even if the new class is serial compatible, you may still want a custom readObject
implementation. you may want this if you want to fill in any new fields which are missing from data saved from old versions of the class (e.g. you have a new List field which you want to initialize to an empty list when loading old class data).
If you want to use jQuery, there is $.merge()
Example:
a = [1, 2];
b = [3, 4, 5];
$.merge(a,b);
Result: a = [1, 2, 3, 4, 5]
Matt's solution didn't work for me on OS X, but Paul's did.
The short version from Paul's link is:
Created /usr/local/bin/ssh_session
with the following text:
#!/bin/bash
export SSH_SESSION=1
if [ -z "$SSH_ORIGINAL_COMMAND" ] ; then
export SSH_LOGIN=1
exec login -fp "$USER"
else
export SSH_LOGIN=
[ -r /etc/profile ] && source /etc/profile
[ -r ~/.profile ] && source ~/.profile
eval exec "$SSH_ORIGINAL_COMMAND"
fi
Execute:
chmod +x /usr/local/bin/ssh_session
Add the following to /etc/sshd_config
:
ForceCommand /usr/local/bin/ssh_session
Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.
Discord supports Markdown and uses highlight.js to highlight code-blocks.
Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.
To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).
```language
message
```
Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).
Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.
It works for some simple drawables. I used it on a simple solid color rect shape with rounded corners and needed to change that color with different layouts.
Try this
android:backgroundTint="#101010"
Yes it is possible without using MySQLi extension.
Simply use CLIENT_MULTI_STATEMENTS
in mysql_connect
's 5th argument.
Refer to the comments below Husni's post for more information.
There is a lot of excellent information here. Unfortunately a lot of this fling-processing code is scattered around on various sites in various states of completion, even though one would think this is essential to many applications.
I've taken the time to create a fling listener that verifies that the appropriate conditions are met. I've added a page fling listener that adds more checks to ensure that flings meet the threshold for page flings. Both of these listeners allow you to easily restrict flings to the horizontal or vertical axis. You can see how it's used in a view for sliding images. I acknowledge that the people here have done most of the research---I've just put it together into a usable library.
These last few days represent my first stab at coding on Android; expect much more to come.
changing the SVG file was not a fair solution for me so instead, I used relative CSS units.
vh
, vw
, %
are very handy. I used a CSS like height: 2.4vh;
to set a dynamic size to my SVG images.
There is and it is not dependent on post build events.
Add the file to your project, then in the file properties select under "Copy to Output Directory" either "Copy Always" or "Copy if Newer".
See MSDN.
Instead of using:
self.present(viewControllerToPresent: UIViewController, animated: Bool, completion: (() -> Void)?)
you can use:
self.navigationController?.pushViewController(viewController: UIViewController, animated: Bool)
