groupByKey()
is just to group your dataset based on a key. It will result in data shuffling when RDD is not already partitioned. reduceByKey()
is something like grouping + aggregation. We can say reduceBykey() equvelent to dataset.group(...).reduce(...). It will shuffle less data unlike groupByKey()
. aggregateByKey()
is logically same as reduceByKey() but it lets you return result in different type. In another words, it lets you have a input as type x and aggregate result as type y. For example (1,2),(1,4) as input and (1,"six") as output. It also takes zero-value that will be applied at the beginning of each key.Note : One similarity is they all are wide operations.
If you are still trying to put files relative to your executable instead of in the temp directory, you need to copy it yourself. This is how I ended up getting it done.

You add a step in the spec file that does a filesystem copy to the DISTPATH variable.
Hope that helps.
return this.lastIndexOf(str) + str.length == this.length;
does not work in the case where original string length is one less than search string length and the search string is not found:
lastIndexOf returns -1, then you add search string length and you are left with the original string's length.
A possible fix is
return this.length >= str.length && this.lastIndexOf(str) + str.length == this.length
If you want to select only one of two nodes with union operator, you can use this solution:
(//bookstore/book/title | //bookstore/city/zipcode/title)[1]
To run the functions in a DLL, first find out what those functions are using any PE (Portable Executable) analysis program (e.g. Dependency Walker). Then use RUNDLL32.EXE with this syntax:
RUNDLL32.EXE <dllname>,<entrypoint> <optional arguments>
dllname is the path and name of your dll file, entrypoint is the function name, and optional arguments are the function arguments
Well, you can declare variables inside the Constructor.
class Foo {
constructor() {
var name = "foo"
this.method = function() {
return name
}
}
}
var foo = new Foo()
foo.method()
I find that psql.exe is quite picky with the slash direction, at least on windows (which the above looks like).
Here's an example. In a cmd window:
C:\Program Files\PostgreSQL\9.2\bin>psql.exe -U postgres
psql (9.2.4)
Type "help" for help.
postgres=# \i c:\temp\try1.sql
c:: Permission denied
postgres=# \i c:/temp/try1.sql
CREATE TABLE
postgres=#
You can see it fails when I use "normal" windows slashes in a \i
call.
However both slash styles work if you pass them as input params to psql.exe
, for example:
C:\Program Files\PostgreSQL\9.2\bin>psql.exe -U postgres -f c:\TEMP\try1.sql
CREATE TABLE
C:\Program Files\PostgreSQL\9.2\bin>psql.exe -U postgres -f c:/TEMP/try1.sql
CREATE TABLE
C:\Program Files\PostgreSQL\9.2\bin>
Easy way that just worked for me:
Then the project will detect it and add the new libraries from the JDK. At the end of this process it looks like the screenshot I attach.
Please correct me if I'm wrong.`

distanceTo will give you the distance in meters between the two given location ej target.distanceTo(destination).
distanceBetween give you the distance also but it will store the distance in a array of float( results[0]). the doc says If results has length 2 or greater, the initial bearing is stored in results[1]. If results has length 3 or greater, the final bearing is stored in results[2]
hope that this helps
i've used distanceTo to get the distance from point A to B i think that is the way to go.
List<string> nameslist = new List<string> {"one", "two", "three"} ?
Since Ruby 2.5.0, Array ships with the prepend
method (which is just an alias for the unshift
method).
Just wrap the float, boolean, int or similar in an NSNumber.
For structs, I don't know of a handy solution, but you could make a separate ObjC class that owns such a struct.
This is the way I prefer:
class Klass(object):
@staticmethod
def stat_func():
return 42
_ANS = stat_func.__func__()
def method(self):
return self.__class__.stat_func() + self.__class__._ANS
I prefer this solution to Klass.stat_func
, because of the DRY principle.
Reminds me of the reason why there is a new super()
in Python 3 :)
But I agree with the others, usually the best choice is to define a module level function.
For instance with @staticmethod
function, the recursion might not look very good (You would need to break DRY principle by calling Klass.stat_func
inside Klass.stat_func
). That's because you don't have reference to self
inside static method.
With module level function, everything will look OK.
You can use :
abs_num = (num < 0) ? -num : num;
Try the following code with an added request property:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class SocketConnection
{
public static String getURLSource(String url) throws IOException
{
URL urlObject = new URL(url);
URLConnection urlConnection = urlObject.openConnection();
urlConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");
return toString(urlConnection.getInputStream());
}
private static String toString(InputStream inputStream) throws IOException
{
try (BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8")))
{
String inputLine;
StringBuilder stringBuilder = new StringBuilder();
while ((inputLine = bufferedReader.readLine()) != null)
{
stringBuilder.append(inputLine);
}
return stringBuilder.toString();
}
}
}
I can recommend Elasticvue, which is modern, free and open source. It allows accessing your ES instance via browser add-ons quite easily (supports Firefox, Chrome, Edge). But there are also further ways.
Just make sure you set cors values in elasticsearch.yml appropiate.
Finally got this error to go away on a restore. I moved to SQL2012 out of frustration, but I guess this would probably still work on 2008R2. I had to use the logical names:
RESTORE FILELISTONLY
FROM DISK = ‘location of your.bak file’
And from there I ran a restore statement with MOVE
using logical names.
RESTORE DATABASE database1
FROM DISK = '\\database path\database.bak'
WITH
MOVE 'File_Data' TO 'E:\location\database.mdf',
MOVE 'File_DOCS' TO 'E:\location\database_1.ndf',
MOVE 'file' TO 'E:\location\database_2.ndf',
MOVE 'file' TO 'E:\location\database_3.ndf',
MOVE 'file_Log' TO 'E:\location\database.ldf'
When it was done restoring, I almost wept with joy.
Good luck!
The direct answer is that you can't. You must select either an aggregate or something that you are grouping by.
So, you need an alternative approach.
1). Take you current query and join the base data back on it
SELECT
cpe.*
FROM
Filteredfmgcms_claimpaymentestimate cpe
INNER JOIN
(yourQuery) AS lookup
ON lookup.MaxData = cpe.createdOn
AND lookup.fmgcms_cpeclaimid = cpe.fmgcms_cpeclaimid
2). Use a CTE to do it all in one go...
WITH
sequenced_data AS
(
SELECT
*,
ROW_NUMBER() OVER (PARITION BY fmgcms_cpeclaimid ORDER BY CreatedOn DESC) AS sequence_id
FROM
Filteredfmgcms_claimpaymentestimate
WHERE
createdon < 'reportstartdate'
)
SELECT
*
FROM
sequenced_data
WHERE
sequence_id = 1
NOTE: Using ROW_NUMBER()
will ensure just one record per fmgcms_cpeclaimid
. Even if multiple records are tied with the exact same createdon
value. If you can have ties, and want all records with the same createdon
value, use RANK()
instead.
Just wanted to add my two cents to this. I tried doing as @Kieveli suggested for non win32 (repeated below) but it didn't work for me (on CentOS with Eclipse: Luna):
java -cp startup.jar -noSplash -data "D:\Source\MyProject\workspace" -application org.eclipse.jdt.apt.core.aptBuild
On my particular setup on CentOS using Eclipse (Luna) this worked:
$ECLIPSE_HOME/eclipse -nosplash -application org.eclipse.jdt.apt.core.aptBuild startup.jar -data ~/workspace
The output should look something like this:
Building workspace
Building '/RemoteSystemsTempFiles'
Building '/test'
Invoking 'Java Builder' on '/test'.
Cleaning output folder for test
Build done
Building workspace
Building '/RemoteSystemsTempFiles'
Building '/test'
Invoking 'Java Builder' on '/test'.
Preparing to build test
Cleaning output folder for test
Copying resources to the output folder
Analyzing sources
Compiling test/src/com/company/test/tool

Not quite sure why it apparently did it twice, but it seems to work.

We have found Jsmooth to be well-working and easily scriptable with ant under Linux. You may want to use one-jar (also easily scriptable with ant under Linux) to collect a multifile application in a single jar first.
We primarily needed the easy deployment of the EXE combined with the "hey, you need Java version X, go here to download" facilities.
(but what you most likely need is the "Runnable jar" / "Executable jar" facility in standard Java).
The error message,
Cannot access database on the main thread since it may potentially lock the UI for a long periods of time.
Is quite descriptive and accurate. The question is how should you avoid accessing the database on the main thread. That is a huge topic, but to get started, read about AsyncTask (click here)
-----EDIT----------
I see you are having problems when you run a unit test. You have a couple of choices to fix this:
Run the test directly on the development machine rather than on an Android device (or emulator). This works for tests that are database-centric and don't really care whether they are running on a device.
Use the annotation
@RunWith(AndroidJUnit4.class)
to run the test on the android device, but not in an activity with a UI.
More details about this can be found in this tutorial
I also met this problem just now and solved it in this way. So I recorded it here, and I wish it be useful for others.
Scenario:
The error occurred.
Solution:
Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming
Update March 2013
Git 1.8.2 added the possibility to track branches.
"
git submodule
" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).
# add submodule to track master branch
git submodule add -b master [URL to Git repo];
# update your submodule
git submodule update --remote
If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".
Also see Vogella's tutorial on submodules for general information on submodules.
Note:
git submodule add -b . [URL to Git repo];
^^^
A special value of
.
is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.
See commit b928922727d6691a3bdc28160f93f25712c565f6:
submodule add
: If --branch
is given, record it in .gitmodules
This allows you to easily record a
submodule.<name>.branch
option in.gitmodules
when you add a new submodule. With this patch,
$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>
reduces to
$ git submodule add -b <branch> <repository> [<path>]
This means that future calls to
$ git submodule update --remote ...
will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):
A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log
within that submodule.
So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:
gitslave (that you already looked at) seems to be the best fit, including for the commit operation.
It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).
Other alternatives are detailed here.
Thanks for the research FIRESTICK is a solution for non Android based but there's another one Im using if you guys want to try it let me know...
LG, VIZIO, SAMSUNG and PANASONIC TVs are not android based, and you cannot run APKs off of them... You should just buy a fire stick and call it a day. The only TVs that are android-based, and you can install APKs are: SONY, PHILIPS and SHARP, PHILCO and TOSHIBA.
I have a simple solution. Create a new Image asset by right clicking your package name and selecting New->Image asset. Enter name (any name) and path (location of image in your system). Then click Next and Finish. If you enter name of image as 'img', a round image with the name 'img_round' is created automatically in mipmap folder.
Then, do this :
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:src="@mipmap/img_round"/>
Your preview may still show a rectangular image. But if you run the app on your device, it will be round.
A server side solution that works for me is: $message = wordwrap($message, 50, "<br>", true);
where $message
is a string variable containing the word/chars to be broken up. 50 is the max length of any given segment, and "<br>"
is the text you want to be inserted every (50) chars.
There is an odd case I got in VS2017, about the space between ‘Any’ and 'CPU'. this is not about using command prompt.
If you have a build project file, which could call other solution files. You can try to add the space between Any and CPU, like this (the Platform property value):
<MSBuild Projects="@(SolutionToBuild2)" Properties ="Configuration=$(ProjectConfiguration);Platform=Any CPU;Rerun=$(MsBuildReRun);" />
Before I fix this build issue, it is like this (ProjectPlatform is a global variable, was set to 'AnyCPU'):
<MSBuild Projects="@(SolutionToBuild1)" Properties ="Configuration=$(ProjectConfiguration);Platform=$(ProjectPlatform);Rerun=$(MsBuildReRun);" />
Also, we have a lot projects being called using $ (ProjectPlatform), which is 'AnyCPU' and work fine. If we open proj file, we can see lines liket this and it make sense.
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release|AnyCPU'">
So my conclusion is, 'AnyCPU' works for calling project files, but not for calling solution files, for calling solution files, using 'Any CPU' (add the space.)
For now, I am not sure if it is a bug of VS project file or MSBuild. I am using VS2017 with VS2017 build tools installed.
Here is a method you can use:
public static void RemoveAllByValue<K, V>(this Dictionary<K, V> dictionary, V value)
{
foreach (var key in dictionary.Where(
kvp => EqualityComparer<V>.Default.Equals(kvp.Value, value)).
Select(x => x.Key).ToArray())
dictionary.Remove(key);
}
Return values are almost always the right choice when the method doesn't have anything else to return. (In fact, I can't think of any cases where I'd ever want a void method with an out
parameter, if I had the choice. C# 7's Deconstruct
methods for language-supported deconstruction acts as a very, very rare exception to this rule.)
Aside from anything else, it stops the caller from having to declare the variable separately:
int foo;
GetValue(out foo);
vs
int foo = GetValue();
Out values also prevent method chaining like this:
Console.WriteLine(GetValue().ToString("g"));
(Indeed, that's one of the problems with property setters as well, and it's why the builder pattern uses methods which return the builder, e.g. myStringBuilder.Append(xxx).Append(yyy)
.)
Additionally, out parameters are slightly harder to use with reflection and usually make testing harder too. (More effort is usually put into making it easy to mock return values than out parameters). Basically there's nothing I can think of that they make easier...
Return values FTW.
EDIT: In terms of what's going on...
Basically when you pass in an argument for an "out" parameter, you have to pass in a variable. (Array elements are classified as variables too.) The method you call doesn't have a "new" variable on its stack for the parameter - it uses your variable for storage. Any changes in the variable are immediately visible. Here's an example showing the difference:
using System;
class Test
{
static int value;
static void ShowValue(string description)
{
Console.WriteLine(description + value);
}
static void Main()
{
Console.WriteLine("Return value test...");
value = 5;
value = ReturnValue();
ShowValue("Value after ReturnValue(): ");
value = 5;
Console.WriteLine("Out parameter test...");
OutParameter(out value);
ShowValue("Value after OutParameter(): ");
}
static int ReturnValue()
{
ShowValue("ReturnValue (pre): ");
int tmp = 10;
ShowValue("ReturnValue (post): ");
return tmp;
}
static void OutParameter(out int tmp)
{
ShowValue("OutParameter (pre): ");
tmp = 10;
ShowValue("OutParameter (post): ");
}
}
Results:
Return value test...
ReturnValue (pre): 5
ReturnValue (post): 5
Value after ReturnValue(): 10
Out parameter test...
OutParameter (pre): 5
OutParameter (post): 10
Value after OutParameter(): 10
The difference is at the "post" step - i.e. after the local variable or parameter has been changed. In the ReturnValue test, this makes no difference to the static value
variable. In the OutParameter test, the value
variable is changed by the line tmp = 10;
First this script test the strings N having chars from 3 to 5.
For multi language (arabic, Ukrainian) you Must use this
var regex = /^([a-zA-Z0-9_-\u0600-\u065f\u066a-\u06EF\u06fa-\u06ff\ufb8a\u067e\u0686\u06af\u0750-\u077f\ufb50-\ufbc1\ufbd3-\ufd3f\ufd50-\ufd8f\ufd92-\ufdc7\ufe70-\ufefc\uFDF0-\uFDFD]+){3,5}$/; regex.test('?????');
Other wise the below is for English Alphannumeric only
/^([a-zA-Z0-9_-]){3,5}$/
P.S the above dose not accept special characters
one final thing the above dose not take space as test it will fail if there is space if you want space then add after the 0-9\s
\s
And if you want to check lenght of all string add dot .
var regex = /^([a-zA-Z0-9\s@,!=%$#&_-\u0600-\u065f\u066a-\u06EF\u06fa-\u06ff\ufb8a\u067e\u0686\u06af\u0750-\u077f\ufb50-\ufbc1\ufbd3-\ufd3f\ufd50-\ufd8f\ufd92-\ufdc7\ufe70-\ufefc\uFDF0-\uFDFD]).{1,30}$/;
segmentation fault arrives when you access memory which is not declared by the program. You can do this through pointers i.e through memory addresses. Or this may also be due to stackoverflow for eg:
void rec_func() {int q = 5; rec_func();}
int main() {rec_func();}
This call will keep on consuming stack memory until it's completely filled and thus finally stackoverflow happens. Note: it might not be visible in some competitive questions as it leads to timeouterror first but for those in which timeout doesn't happens its a hard time figuring out sigsemv.
It seems that your best bet is to redefine the java user.name
variable either at your command line, or using the eclipse.ini
file in your eclipse install root directory.
This seems to work fine for me:
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256M
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Duser.name=Davide Inglima
-Xms40m

Actually if you don't mind using the bandwidth it is more secure for multiple reasons to disable caching and advised by many security sites.
Chromium shouldn't be arrogant enough to make decisions and enforce settings on users.
You can disable the cache on UNIX with --disk-cache-dir=/dev/null.
As this is unexpected crashes may happen but if they do then that will clearly point to a more severe bug which should be fixed in any case.
If you can organize the values in the array in sorted order, then you can use Arrays.binarySearch()
. Otherwise you'll have to write a loop and to a linear search. If you plan to have a large (more than a few dozen) strings in the array, consider using a Set instead.
You must use Color.FromArgb method to create new color structure
var newColor = Color.FromArgb(0xCC,0xBB,0xAA);
Matt's approach above is fine, but please be aware that you will run into problems if you use it to differentiate between dates of the format y/M/d
and d/M/y
. For instance, a formatter initialised with y/M/d
will accept a date like 01/01/2009
and give you back a date which is clearly not what you wanted. I fixed the issue as follows, but I have limited time and I'm not happy with the solution for 2 main reasons:
getDateFormat()
method becoming a bit of a nightmare if you needed it to handle lots of other date formats.If I had to make something that could handle lots and lots of different date formats and needed to be highly performant, then I think I would use the approach of creating an enum which linked each different date regex to its format. Then use MyEnum.values()
to loop through the enum and test with if(myEnum.getPattern().matches(date))
rather than catching a dateformatexception.
Anway, that being said, the following can handle dates of the formats 'y/M/d' 'y-M-d' 'y M d' 'd/M/y' 'd-M-y' 'd M y'
and all other variations of those which include time formats as well:
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class DateUtil {
private static final String[] timeFormats = {"HH:mm:ss","HH:mm"};
private static final String[] dateSeparators = {"/","-"," "};
private static final String DMY_FORMAT = "dd{sep}MM{sep}yyyy";
private static final String YMD_FORMAT = "yyyy{sep}MM{sep}dd";
private static final String ymd_template = "\\d{4}{sep}\\d{2}{sep}\\d{2}.*";
private static final String dmy_template = "\\d{2}{sep}\\d{2}{sep}\\d{4}.*";
public static Date stringToDate(String input){
Date date = null;
String dateFormat = getDateFormat(input);
if(dateFormat == null){
throw new IllegalArgumentException("Date is not in an accepted format " + input);

When your second thread is non-Daemon, your application's primary main thread cannot quit because its exit criteria is being tied to the exit also of non-Daemon thread(s). Threads cannot be forcibly killed in python, therefore your app will have to really wait for the non-Daemon thread(s) to exit. If this behavior is not what you want, then set your second thread as daemon so that it won't hold back your application from exiting.

Try the sql server management studio (version 2008 or earlier) from Microsoft. Download it from here. Not sure about the license, but it seems to be free if you download the EXPRESS EDITION.
You might also be able to use later editions of SSMS. For 2016, you will need to install an extension.
If you have the option you can copy the sdf file to a different machine which you are allowed to pollute with additional software.
Update: comment from Nick Westgate in nice formatting
The steps are not all that intuitive:
- Open SQL Server Management Studio, or if it's running select File -> Connect Object Explorer...
- In the Connect to Server dialog change Server type to SQL Server Compact Edition
- From the Database file dropdown select < Browse for more...>
- Open your SDF file.
Note: This answer shows how to achieve this using only the datetime
and calendar
standard library (stdlib) modules - which is what was explicitly asked for. The accepted answer shows how to better achieve this with one of the many dedicated non-stdlib libraries. If you can use non-stdlib libraries, by all means do so for these kinds of date/time manipulations!
How about this?
def add_one_month(orig_date):
# advance year and month by one month
new_year = orig_date.year
new_month = orig_date.month + 1
# note: in datetime.date, months go from 1 to 12
if new_month > 12:
new_year += 1
new_month -= 12
new_day = orig_date.day
# while day is out of range for month, reduce by one
while True:
try:
new_date = datetime.date(new_year, new_month, new_day)
except ValueError as e:
new_day -= 1
else:
break
return new_date
EDIT:
Improved version which:
calendar.monthrange
from the calendar
module in the stdlib:import datetime
import calendar
def add_one_month(orig_date):
# advance year and month by one month
new_year = orig_date.year
new_month = orig_date.month + 1
# note: in datetime.date, months go from 1 to 12
if new_month > 12:
new_year += 1
new_month -= 12
last_day_of_month = calendar.monthrange(new_year, new_month)[1]
new_day = min(orig_date.day, last_day_of_month)
return orig_date.replace(year=new_year, month=new_month, day=new_day)
Best option is multiple updates.
Alternatively you can do the following but is NOT recommended:
UPDATE table
SET ID = CASE WHEN ID = 2555 THEN 111111259
WHEN ID = 2724 THEN 111111261
WHEN ID = 2021 THEN 111111263
WHEN ID = 2017 THEN 111111264
END
WHERE ID IN (2555,2724,2021,2017)
Any user whose login shell setting in /etc/passwd
is an interactive shell can login. I don't think there's a totally reliable way to tell if a program is an interactive shell; checking whether it's in /etc/shells
is probably as good as you can get.
Other users can also login, but the program they run should not allow them to get much access to the system. And users that aren't allowed to login at all should have /etc/false
as their shell -- this will just log them out immediately.
I think buffers are e.g. useful when interfacing python to native libraries. (Guido van Rossum explains buffer
in this mailinglist post).
For example, numpy seems to use buffer for efficient data storage:
import numpy
a = numpy.ndarray(1000000)
the a.data
is a:
<read-write buffer for 0x1d7b410, size 8000000, offset 0 at 0x1e353b0>

UPDATED: As of angularjs 1.5, promise methods success and error have been deprecated. (see this answer)
from current docs:
$http.get('/someUrl', config).then(successCallback, errorCallback);
$http.post('/someUrl', data, config).then(successCallback, errorCallback);
you can use the function's other arguments like so:
error(function(data, status, headers, config) {
console.log(data);
console.log(status);
}
see $http docs:
// Simple GET request example :
$http.get('/someUrl').
success(function(data, status, headers, config) {
// this callback will be called asynchronously
// when the response is available
}).
error(function(data, status, headers, config) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});
In addition to the answers already given, if you want to create a new directory, you could use this function:
def mkdir_p(mypath):
'''Creates a directory. equivalent to using mkdir -p on the command line'''
from errno import EEXIST
from os import makedirs,path
try:
makedirs(mypath)
except OSError as exc: # Python >2.5
if exc.errno == EEXIST and path.isdir(mypath):
pass
else: raise
and then:
import matplotlib
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(100))
# Create new directory
output_dir = "some/new/directory"
mkdir_p(output_dir)
fig.savefig('{}/graph.png'.format(output_dir))
you can pass an array of strings to str_replace
, so you can do all in a single statement:
$content = str_replace(["\r\n", "\n", "\r"], "", $content);
You can create a character array that does this via a loop:
>> for i=1:10 Names(i,:)='Sample Text'; end >> Names Names = Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text
However, this would be better implemented using REPMAT:
>> Names = repmat('Sample Text', 10, 1) Names = Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text
If the problem is happening on a specific computer,then please try the following fix provided you have Internet Explorer 11.
Please open regedit.exe as an Administrator. Navigate to the following path/paths:
For 32 bit machine:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
For 64 bit machine:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION &
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
And delete the REG_DWORD
value iexplore.exe
.
Please close and relaunch the website using Internet Explorer 11, it will default to Edge as Document Mode.
These 2 cases will take O(log n) time
case 1: f(int n) {

for (i = n; i>=1 ; i=i/2)
printf("%d", i);

I've tested Otaku's answer and it appears that the Outlook bitness value is set even when Outlook is not installed, even though the article referenced does not clearly indicate that this would be the case.
You can try openSSL to generate certificates. Take a look at this.
You are going to need a .key and .crt file to add HTTPS to node JS express server. Once you generate this, use this code to add HTTPS to server.
var https = require('https');
var fs = require('fs');
var express = require('express');
var options = {
key: fs.readFileSync('/etc/apache2/ssl/server.key'),
cert: fs.readFileSync('/etc/apache2/ssl/server.crt'),
requestCert: false,
rejectUnauthorized: false
};
var app = express();
var server = https.createServer(options, app).listen(3000, function(){
console.log("server started at port 3000");
});
This is working fine in my local machine as well as the server where I have deployed this. The one I have in server was bought from goDaddy but localhost had a self signed certificate.
However, every browser threw an error saying connection is not trusted, do you want to continue. After I click continue, it worked fine.
If anyone has ever bypassed this error with self signed certificate, please enlighten.
After searching stackoverflow and the web a lot, I've got to conclution that the best way of doing it is like this:
- (BOOL)isEndDateIsSmallerThanCurrent:(NSDate *)checkEndDate
{
NSDate* enddate = checkEndDate;
NSDate* currentdate = [NSDate date];
NSTimeInterval distanceBetweenDates = [enddate timeIntervalSinceDate:currentdate];
double secondsInMinute = 60;
NSInteger secondsBetweenDates = distanceBetweenDates / secondsInMinute;
if (secondsBetweenDates == 0)
return YES;
else if (secondsBetweenDates < 0)
return YES;
else
return NO;
}
You can change it to difference between hours also.
Enjoy!
If you want to compare date with format of dd/MM/yyyy only, you need to add below lines between NSDate* currentdate = [NSDate date];
&& NSTimeInterval distance
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd/MM/yyyy"];
[dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]
autorelease]];
NSString *stringDate = [dateFormatter stringFromDate:[NSDate date]];
currentdate = [dateFormatter dateFromString:stringDate];
var arr = [1,2,2,3,4,5,5,5,6,7,7,8,9,10,10];
function squash(arr){
var tmp = [];
for(var i = 0; i < arr.length; i++){
if(tmp.indexOf(arr[i]) == -1){
tmp.push(arr[i]);
}
}
return tmp;
}
console.log(squash(arr));

It seems that there is a direct way:
If you really just want to rename branches remotely (without renaming any local branches at the same time) you can do this with a single command like
git push <remote> <remote>/<old_name>:refs/heads/<new_name> :<old_name>

}
int count = yourText.Length - yourText.TrimStart('$').Length;
Another option is to use uniqueResultOptional() method, which gives you Optional in result:
String hql="from DrawUnusedBalance where unusedBalanceDate= :today";
Query query=em.createQuery(hql);
query.setParameter("today",new LocalDate());
Optional<DrawUnusedBalance> drawUnusedBalance=query.uniqueResultOptional();
<input type="file" id="image_control" (change)="validateFile($event)" accept="image/gif, image/jpeg, image/png" />
validateFile(event: any): void {
const self = this;
if (event.target.files.length === 1) {
event.srcElement.value = null;
}
}
This will work:
var dateToday = new Date();
$(function () {
$("#date").datepicker({
minDate: dateToday
});
});
Use a function in place of MidpointRounding.AwayFromZero
:
myRound(1.11125,4)
Answer:- 1.1114
public static Double myRound(Double Value, int places = 1000)
{
Double myvalue = (Double)Value;
if (places == 1000)
{
if (myvalue - (int)myvalue == 0.5)
{
myvalue = myvalue + 0.1;
return (Double)Math.Round(myvalue);
}
return (Double)Math.Round(myvalue);
places = myvalue.ToString().Substring(myvalue.ToString().IndexOf(".") + 1).Length - 1;
} if ((myvalue * Math.Pow(10, places)) - (int)(myvalue * Math.Pow(10, places)) > 0.49)
{
myvalue = (myvalue * Math.Pow(10, places + 1)) + 1;
myvalue = (myvalue / Math.Pow(10, places + 1));
}
return (Double)Math.Round(myvalue, places);
}

Vendor independent version, solely relies on ADO.NET interfaces; 2 ways:
public DataTable Read1<T>(string query) where T : IDbConnection, new()
{
using (var conn = new T())
{
using (var cmd = conn.CreateCommand())
{
cmd.CommandText = query;
cmd.Connection.ConnectionString = _connectionString;
cmd.Connection.Open();
var table = new DataTable();
table.Load(cmd.ExecuteReader());
return table;
}
}
}
public DataTable Read2<S, T>(string query) where S : IDbConnection, new()
where T : IDbDataAdapter, IDisposable, new()
{
using (var conn = new S())
{
using (var da = new T())
{
using (da.SelectCommand = conn.CreateCommand())
{
da.SelectCommand.CommandText = query;
da.SelectCommand.Connection.ConnectionString = _connectionString;
DataSet ds = new DataSet(); //conn is opened by dataadapter
da.Fill(ds);
return ds.Tables[0];
}
}
}
}
I did some performance testing, and the second approach always outperformed the first.
Stopwatch sw = Stopwatch.StartNew();
DataTable dt = null;
for (int i = 0; i < 100; i++)
{
dt = Read1<MySqlConnection>(query); // ~9800ms
dt = Read2<MySqlConnection, MySqlDataAdapter>(query); // ~2300ms
dt = Read1<SQLiteConnection>(query); // ~4000ms
dt = Read2<SQLiteConnection, SQLiteDataAdapter>(query); // ~2000ms
dt = Read1<SqlCeConnection>(query); // ~5700ms
dt = Read2<SqlCeConnection, SqlCeDataAdapter>(query); // ~5700ms
dt = Read1<SqlConnection>(query); // ~850ms
dt = Read2<SqlConnection, SqlDataAdapter>(query); // ~600ms
dt = Read1<VistaDBConnection>(query); // ~3900ms
dt = Read2<VistaDBConnection, VistaDBDataAdapter>(query); // ~3700ms
}
sw.Stop();
MessageBox.Show(sw.Elapsed.TotalMilliseconds.ToString());
Read1
looks better on eyes, but data adapter performs better (not to confuse that one db outperformed the other, the queries were all different). The difference between the two depended on query though. The reason could be that Load
requires various constraints to be checked row by row from the documentation when adding rows (its a method on DataTable
) while Fill
is on DataAdapters which were designed just for that - fast creation of DataTables.
In VSCode for Mac (0.10.6) I opened "Preferences -> User Settings" and placed the following code in the settings.json file

The root of the problem is that you are unknowingly using the Frame
class from the ttk
package rather than from the tkinter
package. The one from ttk
does not support the background option.
This is the main reason why you shouldn't do global imports -- you can overwrite the definition of classes and commands.
I recommend doing imports like this:
import tkinter as tk
import ttk
Then you prefix the widgets with either tk
or ttk
:
f1 = tk.Frame(..., bg=..., fg=...)
f2 = ttk.Frame(..., style=...)
It then becomes instantly obvious which widget you are using, at the expense of just a tiny bit more typing. If you had done this, this error in your code would never have happened.
Now you can also use Talentsoft.Moq.SetupAsync package https://github.com/TalentSoft/Moq.SetupAsync
Which on the base on the answers found here and ideas proposed to Moq but still not yet implemented here: https://github.com/moq/moq4/issues/384, greatly simplify setup of async methods
Few examples found in previous responses done with SetupAsync extension:
mock.SetupAsync(arg=>arg.DoSomethingAsync());
mock.SetupAsync(arg=>arg.DoSomethingAsync()).Callback(() => { <my code here> });
mock.SetupAsync(arg=>arg.DoSomethingAsync()).Throws(new InvalidOperationException());
Just to help out anyone who has landed on this page after updating VS2015 to update 2 and trying to manage packages on a website, receiving the "NuGet configuration file is invalid" error, this is a known and acknowledged issue:
I got mine working again by installing package manager 3.4.4 (beta) from http://dist.nuget.org/index.html
They do also state update 3 for Visual Studio will also contain a fix
If you can use Python, it is even easier if you have the pyopenssl
module. Here it is:
from OpenSSL import crypto
# May require "" for empty password depending on version
with open("push.p12", "rb") as file:
p12 = crypto.load_pkcs12(file.read(), "my_passphrase")
# PEM formatted private key
print crypto.dump_privatekey(crypto.FILETYPE_PEM, p12.get_privatekey())
# PEM formatted certificate
print crypto.dump_certificate(crypto.FILETYPE_PEM, p12.get_certificate())
Use event.source.window.postMessage
to send back to sender.
From Iframe
window.top.postMessage('I am Iframe', '*')
window.onmessage = (event) => {
if (event.data === 'GOT_YOU_IFRAME') {
console.log('Parent received successfully.')
}
}
Then from parent say back.
window.onmessage = (event) => {
event.source.window.postMessage('GOT_YOU_IFRAME', '*')
}
You can use it with your local variables, like this:
@animal = "Dog"
@action = "licks"
@second_animal = "Bird"
"The #{@animal} #{@action} the #{@second_animal}"
the output would be: "The Dog licks the Bird"
BigDecimal decPrec = (BigDecimal)yo.get("Avg");
decPrec = decPrec.setScale(5, RoundingMode.CEILING);
String value= String.valueOf(decPrec);
This way you can set specific precision of a BigDecimal
.
The value of decPrec was 1.5726903423607562595809913132345426
which is rounded off to 1.57267
.
For renaming the columns here is the simple one which will work for both Default(0,1,2,etc;)
and existing columns but not much useful for a larger data sets(having many columns).
For a larger data set we can slice the columns that we need and apply the below code:
df.columns = ['new_name','new_name1','old_name']
As mantioned by Jon Rimmer, you can use GitExtensions. GitExtensions does work in Visual Studio 2005 and Visual Studio 2008, it also does work in Visual Studio 2010 if you manually copy and config the .Addin file.

All you need to do is this: click on (window) on the dropdown manue on top of your screen. click on (Editor). click on (zoom in) as many times as you need to.
i believe the reason it is not working in your example is that you have imported datetime
like so :
from datetime import datetime
this leads to the error you see

/<ipython-input-30-9a298ea6fce5> in <module>()

if you simply import like so :
import datetime
the code will run as shown in all of the other answers

Above answers are helpful, I'd just like to add an example that I think is demonstrating clearly what happens when we pass parameter without the ref keyword, even when that parameter is a reference type:
MyClass c = new MyClass(); c.MyProperty = "foo";
CNull(c); // only a copy of the reference is sent
Console.WriteLine(c.MyProperty); // still foo, we only made the copy null
CPropertyChange(c);
Console.WriteLine(c.MyProperty); // bar
private void CNull(MyClass c2)
{
c2 = null;
}
private void CPropertyChange(MyClass c2)
{
c2.MyProperty = "bar"; // c2 is a copy, but it refers to the same object that c does (on heap) and modified property would appear on c.MyProperty as well.
}
Since PyYAML's yaml.load()
function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:
import yaml
with open('tree.yaml', 'r') as f:
doc = yaml.load(f)
To access branch1 text
you would use:
txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"
because, in your YAML document, the value of the branch1
key is under the treeroot
key.
You can use MySQL variables to do it. Something like this should work (though, it consists of two queries).
SELECT 0 INTO @x;
SELECT itemID,
COUNT(*) AS ordercount,
(@x:=@x+1) AS rownumber
FROM orders
GROUP BY itemID
ORDER BY ordercount DESC;
I think you want Any
:
if (myList.Any(str => str.Contains("Mdd LH")))
It's well worth becoming familiar with the LINQ standard query operators; I would usually use those rather than implementation-specific methods (such as List<T>.ConvertAll
) unless I was really bothered by the performance of a specific operator. (The implementation-specific methods can sometimes be more efficient by knowing the size of the result etc.)
java: Java application executor which is associated with a console to display output/errors
javaw: (Java windowed) application executor not associated with console. So no display of output/errors. It can be used to silently push the output/errors to text files. It is mostly used to launch GUI-based applications.
javaws: (Java web start) to download and run the distributed web applications. Again, no console is associated.
All are part of JRE and use the same JVM.
This the simplest way to assign an async
arrow function expression to a named variable:
const foo = async () => {
// do something
}
(Note that this is not strictly equivalent to async function foo() { }
. Besides the differences between the function
keyword and an arrow expression, the function in this answer is not "hoisted to the top".)
Yes, #id
selectors combined with a multiple selector (comma) is perfectly valid in both jQuery and CSS.
However, for your example, since <script>
comes before the elements, you need a document.ready
handler, so it waits until the elements are in the DOM to go looking for them, like this:
<script>
$(function() {
$("#segement1,#segement2,#segement3").hide()
});
</script>
<div id="segement1"></div>
<div id="segement2"></div>
<div id="segement3"></div>
To assign the font to the textView:
TextView textView = (TextView) findViewById(R.id.your_textView);
final Typeface font = Typeface.createFromAsset(context.getAssets(), "fonts/your_font_name");
your_font_name includes font extension.
If your builds on TravisCI are failing for this particular reason, you can resolve the issue by updating the Django Extensions in your requirements.txt
pip install --upgrade django-extensions
This will update the extensions to use Django 2+ modules.
Simply put, you need to rewrite all of your database connections and queries.
You are using mysql_*
functions which are now deprecated and will be removed from PHP in the future. So you need to start using MySQLi or PDO instead, just as the error notice warned you.
A basic example of using PDO (without error handling):
<?php
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');
$result = $db->exec("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");
$insertId = $db->lastInsertId();
?>
A basic example of using MySQLi (without error handling):
$db = new mysqli($DBServer, $DBUser, $DBPass, $DBName);
$result = $db->query("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");
Here's a handy little PDO tutorial to get you started. There are plenty of others, and ones about the PDO alternative, MySQLi.
You can also do this with named ranges so you don't have to copy the cells from Sheet1 to Sheet2:
Define a named range, say Sheet1Vals
for the column that has the values on which you want to base your condition. You can define a new named range by using the Insert\Name\Define...
menu item. Type in your name, then use the cell browser in the Refers to
box to select the cells you want in the range. If the range will change over time (add or remove rows) you can use this formula instead of selecting the cells explicitly:
=OFFSET('SheetName'!$COL$ROW,0,0,COUNTA('SheetName'!$COL:$COL))
.
Add a -1
before the last )
if the column has a header row.
Define a named range, say Sheet2Vals
for the column that has the values you want to conditionally format.
Use the Conditional Formatting dialog to create your conditions. Specify Formula Is
in the dropdown, then put this for the formula:
=INDEX(Sheet1Vals, MATCH([FirstCellInRange],Sheet2Vals))=[Condition]
where [FirstCellInRange]
is the address of the cell you want to format and [Condition]
is the value your checking.
For example, if my conditions in Sheet1 have the values of 1
, 2
and 3
and the column I'm formatting is column B
in Sheet2 then my conditional formats would be something like:
=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=1
=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=2
=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=3
You can then use the format painter to copy these formats to the rest of the cells.
I like @sjr's answer however I prefer xargs vs -exec. I find xargs more versatile. For example with -P we can take advantage of multiple CPUs when it makes sense to do so.
find . -name '*.pdf' | xargs -P 5 -I % pdftotext % - | grep --with-filename --label="{}" --color "pattern"
To remove anything that is not a number:
$output = preg_replace('/[^0-9]/', '', $input);
Explanation:
[0-9]
matches any number between 0 and 9 inclusively.^
negates a []
pattern.[^0-9]
matches anything that is not a number, and since we're using preg_replace
, they will be replaced by nothing ''
(second argument of preg_replace
).Old post but I made an good solution what is tested on serval places.
https://github.com/CreativForm/Load-jQuery-if-it-is-not-already-loaded
CODE:
(function(url, position, callback){
// default values
url = url || 'https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js';
position = position || 0;
// Check is jQuery exists
if (!window.jQuery) {
// Initialize <head>
var head = document.getElementsByTagName('head')[0];
// Create <script> element
var script = document.createElement("script");
// Append URL
script.src = url;
// Append type
script.type = 'text/javascript';
// Append script to <head>
head.appendChild(script);
// Move script on proper position
head.insertBefore(script,head.childNodes[position]);
script.onload = function(){
if(typeof callback == 'function') {
callback(jQuery);
}
};
} else {
if(typeof callback == 'function') {
callback(jQuery);
}
}
}('https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js', 5, function($){
console.log($);
}));
At GitHub is better explanation but generaly this function you can add anywhere in your HTML code and you will initialize jquery if is not already loaded.
Add your test.js file after the jQuery libraries. This way your test.js file can use the libraries.
I really like those libraries mentioned here but I had an idea that could be simpler than just padding or doing tons of string manipulations,
You could just manually set your cursor using the maximum string length of your data. Here's some code to get the idea (not tested):
var column1[] = {"test", "longer test", "etc"}
var column2[] = {"data", "more data", "etc"}
var offset = strings.OrderByDescending(s => s.Length).First().Length;
for (var i = 0; i < column.Length; i++) {
Console.Write(column[i]);
Console.CursorLeft = offset + 1;
Console.WriteLine(column2[i]);
}
you could easily extrapolate if you have more rows.
You can't guarantee that you're always going to get String
objects back, or that the object you're working with in the List
implements a way to ignore case.
If you do want to compare String
s in a collection to something independent of case, you'd want to iterate over the collection and compare them without case.
String word = "Some word";
List<String> aList = new ArrayList<>(); // presume that the list is populated
for(String item : aList) {
if(word.equalsIgnoreCase(item)) {
// operation upon successful match
}
}
If you have multiple source files, you probably actually want to use link-time-optimization to output one bitcode file for the entire program. The other answers given will cause you to end up with a bitcode file for every source file.
Instead, you want to compile with link-time-optimization
clang -flto -c program1.c -o program1.o
clang -flto -c program2.c -o program2.o
and for the final linking step, add the argument -Wl,-plugin-opt=also-emit-llvm
clang -flto -Wl,-plugin-opt=also-emit-llvm program1.o program2.o -o program
This gives you both a compiled program and the bitcode corresponding to it (program.bc). You can then modify program.bc in any way you like, and recompile the modified program at any time by doing
clang program.bc -o program
although be aware that you need to include any necessary linker flags (for external libraries, etc) at this step again.
Note that you need to be using the gold linker for this to work. If you want to force clang to use a specific linker, create a symlink to that linker named "ld" in a special directory called "fakebin" somewhere on your computer, and add the option
-B/home/jeremy/fakebin
to any linking steps above.
For the instance of
render :json => @projects, :include => :tasks
You are stating that you want to render @projects
as JSON, and include the association tasks
on the Project model in the exported data.
For the instance of
render :json => @projects, :callback => 'updateRecordDisplay'
You are stating that you want to render @projects
as JSON, and wrap that data in a javascript call that will render somewhat like:
updateRecordDisplay({'projects' => []})
This allows the data to be sent to the parent window and bypass cross-site forgery issues.
If you want one md5sum spanning the whole directory, I would do something like
cat *.py | md5sum
As Jake points out, TARGET_IPHONE_SIMULATOR
is a subset of TARGET_OS_IPHONE
.
Also, TARGET_OS_IPHONE
is a subset of TARGET_OS_MAC
.
So a better approach might be:
#ifdef _WIN64
//define something for Windows (64-bit)
#elif _WIN32
//define something for Windows (32-bit)
#elif __APPLE__
#include "TargetConditionals.h"
#if TARGET_OS_IPHONE && TARGET_IPHONE_SIMULATOR
// define something for simulator
#elif TARGET_OS_IPHONE
// define something for iphone
#else
#define TARGET_OS_OSX 1
// define something for OSX
#endif
#elif __linux
// linux
#elif __unix // all unices not caught above
// Unix
#elif __posix
// POSIX
#endif
If you are willing to use an external library, I can't recommend bstrlib
enough. It takes a little extra setup, but is easier to use in the long run.
For example, split the string below, one first creates a bstring
with the bfromcstr()
call. (A bstring
is a wrapper around a char buffer).
Next, split the string on commas, saving the result in a struct bstrList
, which has fields qty
and an array entry
, which is an array of bstring
s.
bstrlib
has many other functions to operate on bstring
s
Easy as pie...
#include "bstrlib.h"
#include <stdio.h>
int main() {
int i;
char *tmp = "Hello,World,sak";
bstring bstr = bfromcstr(tmp);
struct bstrList *blist = bsplit(bstr, ',');
printf("num %d\n", blist->qty);
for(i=0;i<blist->qty;i++) {
printf("%d: %s\n", i, bstr2cstr(blist->entry[i], '_'));
}
}
First you need to make sure that the project has been built. You can build a project with the hammer icon in the toolbar. You can choose to build either a Debug or Release version. If you cannot build the project then the problem is that you either don't have a compiler installed or that the IDE does not find the compiler.
To see if you have a compiler installed in a Mac you can run the following command from the command line:
g++ --version
If you have it already installed (it gets installed when you install the XCode tools) you can see its location running:
which g++
If you were able to build the project but you still get the "binary not found" message then the issue might be that a default launch configuration is not being created for the project. In that case do this:
Right click project > Run As > Run Configurations... >
Then create a new configuration under the "C/C++ Application" section > Enter the full path to the executable file (the file that was created in the build step and that will exist in either the Debug or Release folder). Your launch configuration should look like this:
(Have been studying these, a lot)
Candidate keys - A minimal column combination required to uniquely identify a table row.
Compound keys - 2 or more columns.

If not Exists (select loginname from master.dbo.syslogins
where name = @loginName and dbname = 'PUBS')
Begin
Select @SqlStatement = 'CREATE LOGIN ' + QUOTENAME(@loginName) + '
FROM WINDOWS WITH DEFAULT_DATABASE=[PUBS], DEFAULT_LANGUAGE=[us_english]')
EXEC sp_executesql @SqlStatement
End
You can also use create_function to create a function as a variable and pass it around. Though, I like the feeling of anonymous functions better. Go zombat.
The recommended way is to use requests
module:
#!/usr/bin/env python
import requests # $ python -m pip install requests
####from pip._vendor import requests # bundled with python
url = 'https://httpbin.org/hidden-basic-auth/user/passwd'
user, password = 'user', 'passwd'
r = requests.get(url, auth=(user, password)) # send auth unconditionally
r.raise_for_status() # raise an exception if the authentication fails
Here's a single source Python 2/3 compatible urllib2
-based variant:
#!/usr/bin/env python
import base64
try:
from urllib.request import Request, urlopen
except ImportError: # Python 2
from urllib2 import Request, urlopen
credentials = '{user}:{password}'.format(**vars()).encode()
urlopen(Request(url, headers={'Authorization': # send auth unconditionally
b'Basic ' + base64.b64encode(credentials)})).close()
Python 3.5+ introduces HTTPPasswordMgrWithPriorAuth()
that allows:
..to eliminate unnecessary 401 response handling, or to unconditionally send credentials on the first request in order to communicate with servers that return a 404 response instead of a 401 if the Authorization header is not sent..
#!/usr/bin/env python3
import urllib.request as urllib2
password_manager = urllib2.HTTPPasswordMgrWithPriorAuth()
password_manager.add_password(None, url, user, password,
is_authenticated=True) # to handle 404 variant
auth_manager = urllib2.HTTPBasicAuthHandler(password_manager)
opener = urllib2.build_opener(auth_manager)
opener.open(url).close()
It is easy to replace HTTPBasicAuthHandler()
with ProxyBasicAuthHandler()
if necessary in this case.
The easiest way to reuse the StringBuffer
is to use the method setLength()
public void setLength(int newLength)
You may have the case like
StringBuffer sb = new StringBuffer("HelloWorld");
// after many iterations and manipulations
sb.setLength(0);
// reuse sb
This is very confusing, and if you are using IDE like pycharm, it's little more confusing. What worked for me: 1. Make pycharm project settings (if you are running python from a VE or from python directory) 2. There is no wrong the way you defined. sometime it works with from folder1.file1 import class
if it does not work, use import folder1.file1 3. Your environment variable should be correctly mentioned in system or provide it in your command line argument.
For those using the Appcompat library: If your Activity subclasses ActionBarActivity, you can call supportInvalidateOptionsMenu()

I just encountered the issue and couldn't figure out what was going wrong even after reading all the above and everything out there. What I did was
Each logging implementation has it's own way of setting it via properties or via code(lot of help available on this)
Irrespective of all the above I would not get the logs in my console or my log file. What I had overlooked was the below...
All I was doing with the above jugglery was controlling only the production of the logs(at root/package/class etc), left of the red line in above image. But I was not changing the way displaying/consumption of the logs of the same, right of the red line in above image. Handler(Consumption) is usually defaulted at INFO, therefore your precious debug statements wouldn't come through. Consumption/displaying is controlled by setting the log levels for the Handlers(ConsoleHandler/FileHandler etc..) So I went ahead and set the log levels of all my handlers to finest and everything worked.
This point was not made clear in a precise manner in any place.
I hope someone scratching their head, thinking why the properties are not working will find this bit helpful.
Try using String.getBytes(). It returns a byte[] representing string data. Example:
String data = "sample data";
byte[] byteData = data.getBytes();
The lock
statement is translated to calls to the Enter
and Exit
methods of Monitor
.
The lock
statement will wait indefinitely for the locking object to be released.
Another way to get the same result:
date <- strptime(v,format="%Y%m%d")
You may be misleaded about the username you use locally. That was my case in Windows 10 Home. When I look at users in control panel, I see the name usrpc01. However when I type net config workstation
, it appears that the user's name is spc01. Seems like someone renamed the user, but the internal name remained unchanged.
Not knowing how to fix windows user name (and the folder name under C:\Users
, which also refers to the original internal name), I added a new user accout on my db server.
It turns out that OpenSSL is compiled and enabled in php 5.3 of XAMPP 1.7.2 and so no longer requires a separate extension dll.
However, you STILL need to enable it in your PHP.ini file the line extension=php_openssl.dll
I found the best anwser, it work for me. Clear the value of bootstrap-datepicker:
$('#datepicker').datepicker('setDate', null);
Add value for boostrap-datepicker:
$('#datepicker').datepicker('setDate', datePicker);
On SuSE, there are two different configuration files for PHP: one for Apache, and one for CLI (command line interface). In the /etc/php5/ directory, you will find an "apache2" directory and a "cli" directory. Each has a "php.ini" file. The files are for the same purpose (php configuration), but apply to the two different ways of running PHP. These files, among other things, load the modules PHP uses.
If your OS is similar, then these two files are probably not the same. Your Apache php.ini is probably loading the gearman module, while the cli php.ini isn't. When the module was installed (auto or manual), it probably only updated the Apache php.ini file.
You could simply copy the Apache php.ini file over into the cli directory to make the CLI environment exactly like the Apache environment.
Or, you could find the line that loads the gearman module in the Apache file and copy/paste just it to the CLI file.
From .Net 3.5 you can use LINQ extension method that (sometimes) makes code flow a bit better.
Usage looks like this:
using System.Linq;
// ...
public void My()
{
var myArray = new[] { "abc", "123", "zyx" };
List<string> myList = myArray.ToList();
}
PS. There's also ToArray()
method that works in other way.
Just I want to add something to make your import work and avoid other issues like modules not working in node js. Just note that
With ES6 modules you can not yet import directories. Your import should look like this:
import fs from './../node_modules/file-system/file-system.js'
Actually, it is as simple as setting major
and minor
separately:
In [9]: plot([23, 456, 676, 89, 906, 34, 2345])
Out[9]: [<matplotlib.lines.Line2D at 0x6112f90>]
In [10]: yscale('log')
In [11]: grid(b=True, which='major', color='b', linestyle='-')
In [12]: grid(b=True, which='minor', color='r', linestyle='--')
The gotcha with minor grids is that you have to have minor tick marks turned on too. In the above code this is done by yscale('log')
, but it can also be done with plt.minorticks_on()
.
I just wanted to check if the browser was IE11 or older, because well, they're crap.
function isCrappyIE() {
var ua = window.navigator.userAgent;
var crappyIE = false;
var msie = ua.indexOf('MSIE ');
if (msie > 0) {// IE 10 or older => return version number
crappyIE = true;
}
var trident = ua.indexOf('Trident/');
if (trident > 0) {// IE 11 => return version number
crappyIE = true;
}
return crappyIE;
}
if(!isCrappyIE()){console.table('not a crappy browser);}
Replace the comma with an empty string:
var x = parseFloat("2,299.00".replace(",",""))_x000D_
alert(x);
_x000D_
Got better solution:
$('#element').resizable({
stop: function( event, ui ) {
$('#element').height(ui.originalSize.height);
}
});
We need to remember that the {% endif %}
comes after the {% else %}
.
So this is an example:
{% if someTest %}
<p> Something is True </p>
{% else %}
<p> Something is False </p>
{% endif %}
Strange it doesn't change, as inline styles
are most specific, if style sheet has !important
declared, it wont over ride, try this and see
<span style="font-size: 11px !important; color: #aaaaaa;">Hello</span>
Use ISNULL to overcome it.
Example:
SELECT (ISNULL(field1, '') + '' + ISNULL(field2, '')+ '' + ISNULL(field3, '')) FROM table1
This will then replace your NULL content with an empty string which will preserve the concatentation operation from evaluating as an overall NULL result.
I needed to find the specific version of packages available by default in AWS Lambda. I did so with a mashup of ideas from this page. I'm sharing it for posterity.
import pkgutil
__version__ = '0.1.1'
def get_ver(name):
try:
return str(__import__(name).__version__)
except:
return None
def lambda_handler(event, context):
return {
'statusCode': 200,
'body': [{
'path': m.module_finder.path,
'name': m.name,
'version': get_ver(m.name),
} for m in list(pkgutil.iter_modules())
#if m.module_finder.path == "/var/runtime" # Uncomment this if you only care about a certain path
],
}

What I discovered was also different from what they officially publish. At the time of writing this:
- Operating system – Amazon Linux
- AMI – amzn-ami-hvm-2017.03.1.20170812-x86_64-gp2
- Linux kernel – 4.14.77-70.59.amzn1.x86_64
- AWS SDK for JavaScript – 2.290.0\
- SDK for Python (Boto 3) – 3-1.7.74 botocore-1.10.74
Tried all of the above (short of reboot/ restart docker).
So here is the error om docker rm:
$ docker rm 08d51aad0e74
Error response from daemon: driver "devicemapper" failed to remove root filesystem for 08d51aad0e74060f54bba36268386fe991eff74570e7ee29b7c4d74047d809aa: remove /var/lib/docker/devicemapper/mnt/670cdbd30a3627ae4801044d32a423284b540c5057002dd010186c69b6cc7eea: device or resource busy
Then I did a the following:
$ grep docker /proc/*/mountinfo | grep 958722d105f8586978361409c9d70aff17c0af3a1970cb3c2fb7908fe5a310ac

This got be the PID of the offending process keeping it busy - 20416 (the item after /proc/
So I did a ps -p and to my surprise find:
[devops@dp01app5030 SeGrid]$ ps -p 20416

20416 ? 00:00:19 ntpd
A true WTF moment. So I pair problem solved with Google and found this: Then found this https://github.com/docker/for-linux/issues/124
Turns out I had to restart ntp daemon and that fixed the issue!!!
Seems like a bad way to do it (creating two correlated lists) but I'm assuming you have your reasons.
I'd parse the JSON string (which has a typo in your example, it's missing a comma between the two objects) into a strongly-typed object and then use a couple of LINQ queries to get the two lists.
void Main()
{
string json = "{\"People\":[{\"FirstName\":\"Hans\",\"LastName\":\"Olo\"},{\"FirstName\":\"Jimmy\",\"LastName\":\"Crackedcorn\"}]}";

Your method will return a local stack variable that will fail badly. To return an array, create one outside the function, pass it by address into the function, then modify it, or create an array on the heap and return that variable. Both will work, but the first doesn't require any dynamic memory allocation to get it working correctly.
void returnArray(int size, char *retArray)
{
// work directly with retArray or memcpy into it from elsewhere like
// memcpy(retArray, localArray, size);
}
#define ARRAY_SIZE 20
int main(void)
{
char foo[ARRAY_SIZE];
returnArray(ARRAY_SIZE, foo);
}

Recently I wrote it in Java to obfuscate my PHP projects, because I didnt find any good and compatible ready written on the net, I decided to put it online as saas, so everyone use it free. It does not change variable names between different scripts for maximum compatibility, but is obfuscating them very good, with random logic, every instruction too. Strings... everything. I believe its much better then this buggy codeeclipse, that is by the way written in PHP and very slow :)
Generally, you cannot send a POST request using sendRedirect() method. You can use RequestDispatcher to forward() requests with parameters within the same web application, same context.
RequestDispatcher dispatcher = servletContext().getRequestDispatcher("test.jsp");
dispatcher.forward(request, response);
The HTTP spec states that all redirects must be in the form of a GET (or HEAD). You can consider encrypting your query string parameters if security is an issue. Another way is you can POST to the target by having a hidden form with method POST and submitting it with javascript when the page is loaded.
Why is printf("%8d\n", intval);
not working for you? It should...
You did not show the format strings for any of your "not working" examples, so I'm not sure what else to tell you.
#include <stdio.h>
int
main(void)
{
int i;
for (i = 1; i <= 10000; i*=10) {
printf("[%8d]\n", i);
}
return (0);
}
$ ./printftest
[ 1]
[ 10]
[ 100]
[ 1000]
[ 10000]
EDIT: response to clarification of question:
#include <math.h>
int maxval = 1000;
int width = round(1+log(maxval)/log(10));
...
printf("%*d\n", width, intval);
The width calculation computes log base 10 + 1, which gives the number of digits. The fancy *
allows you to use the variable for a value in the format string.
You still have to know the maximum for any given run, but there's no way around that in any language or pencil & paper.
Use shell=True
if you're passing a string to subprocess.call
.
From docs:
If passing a single string, either
shell
must beTrue
or else the string must simply name the program to be executed without specifying any arguments.
subprocess.call(crop, shell=True)
or:
import shlex
subprocess.call(shlex.split(crop))
git clone <Repo> <DestinationDirectory>
Clone the repository located at Repo into the folder called DestinationDirectory on the local machine.
# here database details
mysql_connect('hostname', 'username', 'password');
mysql_select_db('database-name');
$sql = "SELECT username FROM userregistraton";
$result = mysql_query($sql);
echo "<select name='username'>";
while ($row = mysql_fetch_array($result)) {
echo "<option value='" . $row['username'] ."'>" . $row['username'] ."</option>";
}
echo "</select>";
# here username is the column of my table(userregistration)
# it works perfectly

What fixed this for me was that I had a React component being rendered prior to my core.js shim being loaded.
import ReactComponent from '.'
import 'core-js/es6'
Loading the core-js prior to the ReactComponent fixed my issue
import 'core-js/es6'
import ReactComponent from '.'
A dozen pages is not a big deal when using OFFSET
. But when you have hundreds of pages, you will find that OFFSET
is bad for performance. This is because all the skipped rows need to be read each time.
It is better to remember where you left off.
Candidate Key: The candidate key can be defined as minimal set of attribute which can uniquely identify a tuple is known as candidate key. For Example, STUD_NO in below STUDENT relation.
- The value of Candidate Key is unique and non-null for every tuple.
- There can be more than one candidate key in a relation. For Example, STUD_NO as well as STUD_PHONE both are candidate keys for relation STUDENT.
- The candidate key can be simple (having only one attribute) or composite as well. For Example, {STUD_NO, COURSE_NO} is a composite
candidate key for relation STUDENT_COURSE.
Super Key: The set of attributes which can uniquely identify a tuple is known as Super Key. For Example, STUD_NO, (STUD_NO, STUD_NAME) etc. Adding zero or more attributes to candidate key generates super key. A candidate key is a super key but vice versa is not true. Primary Key: There can be more than one candidate key in a relation out of which one can be chosen as primary key. For Example, STUD_NO as well as STUD_PHONE both are candidate keys for relation STUDENT but STUD_NO can be chosen as primary key (only one out of many candidate keys).
Alternate Key: The candidate key other than primary key is called as alternate key. For Example, STUD_NO as well as STUD_PHONE both are candidate keys for relation STUDENT but STUD_PHONE will be alternate key (only one out of many candidate keys).
Foreign Key: If an attribute can only take the values which are present as values of some other attribute, it will be foreign key to the attribute to which it refers. The relation which is being referenced is called referenced relation and corresponding attribute is called referenced attribute and the relation which refers to referenced relation is called referencing relation and corresponding attribute is called referencing attribute. Referenced attribute of referencing attribute should be primary key. For Example, STUD_NO in STUDENT_COURSE is a foreign key to STUD_NO in STUDENT relation.
Assuming that you don't have a library or system header that defines NULL
as for example (void*)0
or (char*)0
it's fine. I always tend to use 0 myself as it is by definition the null pointer. In c++0x you'll have nullptr
available so the question won't matter as much anymore.
You can use another tag instead of input
and apply FontAwesome the normal way.
instead of your input
with type image
you can use this:
<i class="icon-search icon-2x"></i>
quick CSS:
.icon-search {
color:white;
background-color:black;
}
Here is a quick fiddle: DEMO
You can style it a little better and add event functionality, to the i object, which you can do by using a <button type="submit">
object instead of i
, or with javascript.
The button sollution would be something like this:
<button type="submit" class="icon-search icon-large"></button>
And the CSS:
.icon-search {
height:32px;
width:32px;
border: none;
cursor: pointer;
color:white;
background-color:black;
position:relative;
}
here is my fiddle updated with the button instead of i: DEMO
The problem with FontAwsome is that its stylesheet uses :before
pseudo-elements to add the icons to an element - and pseudo elements don't work/are not allowed on input
elements. This is why using FontAwesome the normal way will not work with input
.
But there is a solution - you can use FontAwesome as a regular font like so:
CSS:
input[type="submit"] {
font-family: FontAwesome;
}
HTML:
<input type="submit" class="search" value="" />
The glyphs can be passed as values of the value
attribute. The ascii codes for the individual letters/icons can be found in the FontAwesome css file, you just need to change them into a HTML ascii number like \f002
to 
and it should work.
Link to the FontAwesome ascii code (cheatsheet): fortawesome.github.io/Font-Awesome/cheatsheet
The size of the icons can be easily adjusted via font-size
.
See the above example using an input
element in a jsfidde:
With FontAwesome version 5 the CSS required for this solution has changed - the font family name has changed and the font weight must be specified:
input[type="submit"] {
font-family: "Font Awesome 5 Free"; // for the open access version
font-size: 1.3333333333333333em;
font-weight: 900;
}
See @WillFastie 's comment with link to updated fiddle bellow. Thanks!
When I create a root class, whose methods I defined using the arrow functions. When inheriting and overwriting the original function I noticed the same issue.
class C {
x = () => 1;
};
class CC extends C {
x = (foo) => super.x() + foo;
};
let add = new CC;
console.log(add.x(4));
this is solved by defining the method of the parent class without arrow functions
class C {
x() {
return 1;
};
};
class CC extends C {
x = foo => super.x() + foo;
};
let add = new CC;
console.log(add.x(4));
I don't think this is possible. As far as I know, the only time a browser doesn't scroll to a changed document.location.hash
is if the hash doesn't exist within the page.
This article isn't directly related to your question, but it discusses typical browser behavior of changing document.location.hash
Using the Maven artifact org.json:json
I got the following code, which I think is quite short. Not as short as possible, but still usable.

public class JsonReader {
private static String readAll(Reader rd) throws IOException {
StringBuilder sb = new StringBuilder();
int cp;
while ((cp = rd.read()) != -1) {
sb.append((char) cp);
}
return sb.toString();
}
public static JSONObject readJsonFromUrl(String url) throws IOException, JSONException {
InputStream is = new URL(url).openStream();
try {
BufferedReader rd = new BufferedReader(new InputStreamReader(is, Charset.forName("UTF-8")));
String jsonText = readAll(rd);

Swift 4.1 and 5. We use queues in many places in our code. So, I created Threads class with all queues. If you don't want to use Threads class you can copy the desired queue code from class methods.
class Threads {
static let concurrentQueue = DispatchQueue(label: "AppNameConcurrentQueue", attributes: .concurrent)
static let serialQueue = DispatchQueue(label: "AppNameSerialQueue")
// Main Queue
class func performTaskInMainQueue(task: @escaping ()->()) {
DispatchQueue.main.async {
task()
}
}
// Background Queue
class func performTaskInBackground(task:@escaping () throws -> ()) {
DispatchQueue.global(qos: .background).async {
do {
try task()
} catch let error as NSError {
print("error in background thread:\(error.localizedDescription)")
}
}
}
// Concurrent Queue
class func perfromTaskInConcurrentQueue(task:@escaping () throws -> ()) {
concurrentQueue.async {
do {
try task()
} catch let error as NSError {
print("error in Concurrent Queue:\(error.localizedDescription)")
}
}
}
// Serial Queue
class func perfromTaskInSerialQueue(task:@escaping () throws -> ()) {
serialQueue.async {
do {
try task()
} catch let error as NSError {
print("error in Serial Queue:\(error.localizedDescription)")
}
}
}
// Perform task afterDelay
class func performTaskAfterDealy(_ timeInteval: TimeInterval, _ task:@escaping () -> ()) {
DispatchQueue.main.asyncAfter(deadline: (.now() + timeInteval)) {
task()
}
}
}
Example showing the use of main queue.
override func viewDidLoad() {
super.viewDidLoad()
Threads.performTaskInMainQueue {
//Update UI
}
}
For a list of available flags:
grep --help
Returns all matches for the regexp texthere in the current directory, with the corresponding line number:
grep -rn "texthere" .
Returns all matches for texthere, starting at the root directory, with the corresponding line number and ignoring case:
grep -rni "texthere" /
flags used here:
-r
recursive -n
print line number with output -i
ignore caseYou can add it like this
header('Location: http://linkhere.com/'.$url_endpoint);
You need to separate the arguments from the file path:
powershell.exe -noexit "& 'D:\Work\SQLExecutor.ps1 ' -gettedServerName 'MY-PC'"
Another option that may ease the syntax using the File parameter and positional parameters:
powershell.exe -noexit -file "D:\Work\SQLExecutor.ps1" "MY-PC"
create table a1
(weddingTable INT(3),

I faced the same issue and was not able to find it out where git.exe is located. After spending so much time I fount that in my windows 8, it is located at
C:\Program Files (x86)\Git\bin
And for command line :
C:\Program Files (x86)\Git\cmd
Hope this helps someone facing the same issue.
I usually shy away from queries from sys* type tables, vendors tend to change these between releases, major or otherwise. What I have always done is to issue the DROP FUNCTION <name>
statement and not worry about any SQL error that might come back. I consider that standard procedure in the DBA realm.
How much shorter do you want it to be? It is only an extra 2 lines AND it is clear and concise logic.
I think the more important thing you need to decide is if null
is a valid value or not. If they are not valid, you should write you code to prevent it from happening. Then you would not need this kind of check. If you go get an exception while doing a foreach
loop, that is a sign that there is a bug somewhere else in your code.
In JavaScript 1.7 and higher you can use array comprehensions to create two dimensional arrays. You can also filter and/or manipulate the entries while filling the array and don't have to use loops.
var rows = [1, 2, 3];
var cols = ["a", "b", "c", "d"];
var grid = [ for (r of rows) [ for (c of cols) r+c ] ];
/*
grid = [
["1a","1b","1c","1d"],
["2a","2b","2c","2d"],
["3a","3b","3c","3d"]
]
*/
You can create any n x m
array you want and fill it with a default value by calling
var default = 0; // your 2d array will be filled with this value
var n_dim = 2;
var m_dim = 7;
var arr = [ for (n of Array(n_dim)) [ for (m of Array(m_dim) default ]]
/*
arr = [
[0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0],
]
*/
More examples and documentation can be found here.
Please note that this is not a standard feature yet.
Another solution is to use stat_count()
when dealing with discrete variables (and stat_bin()
with continuous ones).
ggplot(data = df, aes(x = x)) +
geom_bar(stat = "count") +
stat_count(geom = "text", colour = "white", size = 3.5,
aes(label = ..count..),position=position_stack(vjust=0.5))
I also had same issue. I investigated and found missing {action} attribute from route template.
Before code (Having Issue):
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
After Fix(Working code):
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
For MVC, ignore input validation by adding
[ValidateInput(false)]
above each Action in the Controller.
How about defining your own view? I have used the class below, using a LinearLayout around a view whose background color is set. This allows me to pre-define layout parameters for it. If you don't need that just extend View and set the background color instead.
public class HorizontalRulerView extends LinearLayout {
static final int COLOR = Color.DKGRAY;
static final int HEIGHT = 2;
static final int VERTICAL_MARGIN = 10;
static final int HORIZONTAL_MARGIN = 5;
static final int TOP_MARGIN = VERTICAL_MARGIN;
static final int BOTTOM_MARGIN = VERTICAL_MARGIN;
static final int LEFT_MARGIN = HORIZONTAL_MARGIN;
static final int RIGHT_MARGIN = HORIZONTAL_MARGIN;
public HorizontalRulerView(Context context) {
this(context, null);
}
public HorizontalRulerView(Context context, AttributeSet attrs) {
this(context, attrs, android.R.attr.textViewStyle);
}
public HorizontalRulerView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setOrientation(VERTICAL);
View v = new View(context);
v.setBackgroundColor(COLOR);
LayoutParams lp = new LayoutParams(
LayoutParams.MATCH_PARENT,
HEIGHT
);
lp.topMargin = TOP_MARGIN;
lp.bottomMargin = BOTTOM_MARGIN;
lp.leftMargin = LEFT_MARGIN;
lp.rightMargin = RIGHT_MARGIN;
addView(v, lp);
}
}
Use it programmatically or in Eclipse (Custom & Library Views -- just pull it into your layout).
With the new App Launcher YOUR APPS (not chrome extensions) stored in Users/[yourusername]/Applications/Chrome Apps/

The best way I've found to do it is run Reloader
It allows you to define configmaps or secrets to watch, when they get updated, a rolling update of your deployment is performed. Here's an example:
You have a deployment foo
and a ConfigMap called foo-configmap
. You want to roll the pods of the deployment every time the configmap is changed. You need to run Reloader with:
kubectl apply -f https://raw.githubusercontent.com/stakater/Reloader/master/deployments/kubernetes/reloader.yaml
Then specify this annotation in your deployment:
kind: Deployment
metadata:
annotations:
configmap.reloader.stakater.com/reload: "foo-configmap"
name: foo
...
You have $headers .= '...';
followed by $headers = '...';
; the second line is overwriting the first.
Just put the $headers .= "Bcc: $emailList\r\n";
say after the Content-type
line and it should be fine.
On a side note, the To
is generally required; mail servers might mark your message as spam otherwise.
$headers = "From: [email protected]\r\n" .
"X-Mailer: php\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= "Bcc: $emailList\r\n";
Yes it is possible but you can better use a div #mydiv and use both
$(document).ready(function(){});
//and
$("#mydiv").ready(function(){});
Short Code
public class DB {
public static Connection c;
public static Connection getConnection() throws Exception {
if (c == null) {
Class.forName("com.mysql.jdbc.Driver");
c =DriverManager.getConnection("jdbc:mysql://localhost:3306/DATABASE", "USERNAME", "Password");
}
return c;
}
// Send data TO Database
public static void setData(String sql) throws Exception {
DB.getConnection().createStatement().executeUpdate(sql);
}
// Get Data From Database
public static ResultSet getData(String sql) throws Exception {
ResultSet rs = DB.getConnection().createStatement().executeQuery(sql);
return rs;
}
}
The S parameter does not do anything on its own.
/S Modifies the treatment of string after /C or /K (see below)
/C Carries out the command specified by string and then terminates
/K Carries out the command specified by string but remains
Try something like this instead
Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)
You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.
Shell("perl a.pl c:\temp")
-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here
Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1
wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn
Arrays.sort(numArray);
return (numArray[size/2] + numArray[(size-1)/2]) / 2;
I have used this wrapper (Recommended) written by google developers. Its super easy to use.
https://github.com/googlesamples/easypermissions
Function dealing with checking and ask for permission if required
public void locationAndContactsTask() {
String[] perms = { Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.READ_CONTACTS };
if (EasyPermissions.hasPermissions(this, perms)) {
// Have permissions, do the thing!
Toast.makeText(this, "TODO: Location and Contacts things", Toast.LENGTH_LONG).show();
} else {
// Ask for both permissions
EasyPermissions.requestPermissions(this, getString(R.string.rationale_location_contacts),
RC_LOCATION_CONTACTS_PERM, perms);
}
}
Happy coding :)
The Python parser evaluated that statement as a tuple, where the first value was 'a'
, and the second value is the expression 'b' in ['b', 'a', 'foo', 'bar']
(which evaluates to True
).
You can write a simple function do do what you want, though:
def all_in(candidates, sequence):
for element in candidates:
if element not in sequence:
return False
return True
And call it like:
>>> all_in(('a', 'b'), ['b', 'a', 'foo', 'bar'])
True
As MRA said, you shouldn't try to dodge a 429 Too Many Requests
but instead handle it accordingly. You have several options depending on your use-case:
1) Sleep your process. The server usually includes a Retry-after
header in the response with the number of seconds you are supposed to wait before retrying. Keep in mind that sleeping a process might cause problems, e.g. in a task queue, where you should instead retry the task at a later time to free up the worker for other things.
2) Exponential backoff. If the server does not tell you how long to wait, you can retry your request using increasing pauses in between. The popular task queue Celery has this feature built right-in.
3) Token bucket. This technique is useful if you know in advance how many requests you are able to make in a given time. Each time you access the API you first fetch a token from the bucket. The bucket is refilled at a constant rate. If the bucket is empty, you know you'll have to wait before hitting the API again. Token buckets are usually implemented on the other end (the API) but you can also use them as a proxy to avoid ever getting a 429 Too Many Requests
. Celery's rate_limit feature uses a token bucket algorithm.
Here is an example of a Python/Celery app using exponential backoff and rate-limiting/token bucket:
class TooManyRequests(Exception):
"""Too many requests"""
@task(
rate_limit='10/s',
autoretry_for=(ConnectTimeout, TooManyRequests,),
retry_backoff=True)
def api(*args, **kwargs):
r = requests.get('placeholder-external-api')
if r.status_code == 429:
raise TooManyRequests()
For those who don't want to remember the syntax everytime here is a simple encapsulation:
public class FileDialogFilter : List<string>
{
public string Explanation { get; }
public FileDialogFilter(string explanation, params string[] extensions)
{
Explanation = explanation;
AddRange(extensions);
}
public string GetFileDialogRepresentation()
{
if (!this.Any())
{
throw new ArgumentException("No file extension is defined.");
}
StringBuilder builder = new StringBuilder();
builder.Append(Explanation);
builder.Append(" (");
builder.Append(String.Join(", ", this));
builder.Append(")");
builder.Append("|");
builder.Append(String.Join(";", this));
return builder.ToString();
}
}
public class FileDialogFilterCollection : List<FileDialogFilter>
{
public string GetFileDialogRepresentation()
{
return String.Join("|", this.Select(filter => filter.GetFileDialogRepresentation()));
}
}
Usage:
FileDialogFilter filterImage = new FileDialogFilter("Image Files", "*.jpeg", "*.bmp");
FileDialogFilter filterOffice = new FileDialogFilter("Office Files", "*.doc", "*.xls", "*.ppt");
FileDialogFilterCollection filters = new FileDialogFilterCollection
{
filterImage,
filterOffice
};
OpenFileDialog fileDialog = new OpenFileDialog
{
Filter = filters.GetFileDialogRepresentation()
};
fileDialog.ShowDialog();
There are a few ways to do it, but i think one of the quicker ways is the following
// $filename has the file name you have under the picture
$temp = explode( '.', $filename );
$ext = array_pop( $temp );
$name = implode( '.', $temp );
Another solution is this. I havent tested it, but it looks like it should work for multiple periods in a filename
$name = substr($filename, 0, (strlen ($filename)) - (strlen (strrchr($filename,'.'))));
Also:
$info = pathinfo( $filename );
$name = $info['filename'];
$ext = $info['extension'];
// Or in PHP 5.4, i believe this should work
$name = pathinfo( $filename )[ 'filename' ];
In all of these, $name
contains the filename without the extension
What about using offset?
<div class="row">
<div class="col-sm-8 offset-sm-2 col-lg-2 offset-lg-1">
1
</div>
<div class="col-sm-8 offset-sm-2 col-lg-2 offset-lg-0">
2
</div>
<div class="col-sm-8 offset-sm-2 col-lg-2 offset-lg-0">
3
</div>
<div class="col-sm-8 offset-sm-2 col-lg-2 offset-lg-0">
4
</div>
<div class="col-sm-8 offset-sm-2 col-lg-2 offset-lg-0">
5
</div>
</div>
SLF4J 1.5.11 and 1.6.0 versions are not compatible (see compatibility report) because the argument list of org.slf4j.spi.LocationAwareLogger.log
method has been changed (added Object[] p5):
SLF4J 1.5.11:
LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
String p4, Throwable p5 )
SLF4J 1.6.0:
LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
String p4, Object[] p5, Throwable p6 )
See compatibility reports for other SLF4J versions on this page.
You can generate such reports by the japi-compliance-checker tool.
It's easy maybe you have error in the configuration.
For Example: Manifest.xml
But in my configuration have for default Activity .Splash
you need check this configuration and the file Manifest.xml
Good Luck
When I run in a similar issue, in Vs 2012, it turned out that the "Custom Tool Namespace" property of the resx file was wrong (in my case, actually, it was unset, so the generated code yeld this exception at runtime). My final set of properties for the resx file was something like this:
You may have accidentally cloned the repository in https instead of ssh. I've made this mistake numerous times on github. Make sure that you copy the ssh link in the first place when cloning, instead of the https link.
Be consistent and it doesn't matter which one. Also if for some reason you must interop with another program or tool using a certain DEBUG identifier it's easy to do
#ifdef THEIRDEBUG
#define MYDEBUG
#endif //and vice-versa
If you aren't comfortable with using negative margins, check this out.
div {
position: fixed;
left: 50%;
bottom: 20px;
transform: translate(-50%, -50%);
margin: 0 auto;
}
<div>
Your Text
</div>
Especially useful when you don't know the width of the div.
align="center"
has no effect.
Since you have position:absolute
, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.
#manipulate {
position:absolute;
width:300px;
height:300px;
background:#063;
bottom:0px;
right:25%;
left:50%;
margin-left:-150px;
}
Another option is to add it to the jest.config.js
file after the module.exports
definition:
process.env = Object.assign(process.env, {
VAR_NAME: 'varValue',
VAR_NAME_2: 'varValue2'
});
This way it's not necessary to define the environment variables in each .spec
file and they can be adjusted globally.
The child views in your list row should be considered selected whenever the parent row is selected, so you should be able to just set a normal state drawable/color-list on the views you want to change, no messy Java code necessary. See this SO post.
Specifically, you'd set the textColor
of your textViews to an XML resource like this one:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:drawable="@color/black" /> <!-- focused -->
<item android:state_focused="true" android:state_pressed="true" android:drawable="@color/black" /> <!-- focused and pressed-->
<item android:state_pressed="true" android:drawable="@color/green" /> <!-- pressed -->
<item android:drawable="@color/black" /> <!-- default -->
</selector>
Auto reload with target of your choice. In this case target is _self
set to every 5 minutes.
300000 milliseconds = 300 seconds = 5 minutes
as 60000 milliseconds = 60 seconds = 1 minute.
This is how you do it:
<script type="text/javascript">
function load()
{
setTimeout("window.open('http://YourPage.com', '_self');", 300000);
}
</script>
<body onload="load()">
Or this if it is the same page to reload itself:
<script type="text/javascript">
function load()
{
setTimeout("window.open(self.location, '_self');", 300000);
}
</script>
<body onload="load()">
You need to use an explicit color value (e.g. #000
or blue
) for the color
-property. none
is invalid here. The initial value is browser-specific and cannot be restored using CSS. Keep in mind that there are some other pseudo-classes than :active
, too.
The answers at the other link will work, but to serve out HTML, there is no need to use a view engine at all, unless you want to set up funky routing. Instead, just use the static middleware:
app.use(express.static(__dirname + '/public'));
You most probably don't need z-index to do that. You can use relative and absolute positioning.
I advise you to take a better look at css positioning and the difference between relative and absolute positioning... I saw you're setting position: absolute;
to an element and trying to float that element. It won't work friend! When you understand positioning in CSS it will make your work a lot easier! ;)
Edit: Just to be clear, positioning is not a replacement for them and I do use z-index
. I just try to avoid using them. Using z-indexes
everywhere seems easy and fun at first... until you have bugs related to them and find yourself having to revisit and manage z-indexes
.
I made this:
function repeat(func, times) {
for (var i=0; i<times; i++) {
func(i);
}
}
Usage:
repeat(function(i) {
console.log("Hello, World! - "+i);
}, 5)
/*
Returns:
Hello, World! - 0
Hello, World! - 1
Hello, World! - 2
Hello, World! - 3
Hello, World! - 4
*/
The i
variable returns the amount of times it has looped - useful if you need to preload an x amount of images.
Another Alternative for the command line that is easier than fighting with quotation marks is to put the json into a file, and use the @ prefix of curl parameters, e.g. with the following in json.txt:
{ "syncheader" : {
"servertimesync" : "20131126121749",
"deviceid" : "testDevice"
}
}
then in my case I issue:
curl localhost:9000/sync -H "Content-type:application/json" -X POST -d @json.txt
Keeps the json more readable too.
The above code will certainly help in converting HTML to PDF but will fail if the the HTML code has IMG tags with relative paths. iTextSharp library does not automatically convert relative paths to absolute ones.
I tried the above code and added code to take care of IMG tags too.
You can find the code here for your reference: http://www.am22tech.com/html-to-pdf/
This works for all types.
List<object> objects = new List<object>();
List<string> strings = objects.Select(s => (string)s).ToList();
This is the function that has always helped me convert the xml related values to array
function _xml2array ( $xmlObject, $out = array () ){
foreach ( (array) $xmlObject as $index => $node )
$out[$index] = ( is_object ( $node ) ) ? _xml2array ( $node ) : $node;
return $out;
}
There are several causes for this error.
wait_timeout
- Time in seconds that the server waits for a connection to become active before closing it.interactive_timeout
- Time in seconds that the server waits for an interactive connection.max_allowed_packet
- Maximum size in bytes of a packet or a generated/intermediate string. Set as large as the largest BLOB, in multiples of 1024.Example of my.cnf:
[mysqld]
# 8 hours
wait_timeout = 28800
# 8 hours
interactive_timeout = 28800
max_allowed_packet = 256M
