I had below error:
Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.
Solution was to revert the NAME to jenkins in the below file (Earlier I have changed it to 'NAME=ubuntu'):
sudo vi /etc/default/jenkins
NAME=jenkins
Now restart passed:
sudo service jenkins restart
sudo systemctl restart jenkins.service
Hope that helps.
Spent much of my time with this! My bad! Later found that the class on which I declared the annotation Service
or Component
was of type abstract. Had enabled debug logs on Springframework but no hint was received. Please check if the class if of abstract type. If then, the basic rule applied, can't instantiate an abstract class.
If you use private static variables in your class, Static Inner classes in your class can reach your variables. This is perfectly good for context security.
In my case it was quite a stupid thing. I've get used that new entities are created using POST and it was failing with "Missing Authentication Token". I've missed that for some reason it was defined as PUT which is working fine.
If you have your arguments in an array, you might be interested by the call_user_func_array
function.
If the number of arguments you want to pass depends on the length of an array, it probably means you can pack them into an array themselves -- and use that one for the second parameter of call_user_func_array
.
Elements of that array you pass will then be received by your function as distinct parameters.
For instance, if you have this function :
function test() {
var_dump(func_num_args());
var_dump(func_get_args());
}
You can pack your parameters into an array, like this :
$params = array(
10,
'glop',
'test',
);
And, then, call the function :
call_user_func_array('test', $params);
This code will the output :
int 3
array
0 => int 10
1 => string 'glop' (length=4)
2 => string 'test' (length=4)
ie, 3 parameters ; exactly like iof the function was called this way :
test(10, 'glop', 'test');
Since you seem to be on windows you can do this so python <filename.py>
. Check that python's bin folder is in your PATH, or you can do c:\python23\bin\python <filename.py>
. Python is an interpretive language and so you need the interpretor to run your file, much like you need java runtime to run a jar file.
Actually this can happens because of two reason.
Your project not getting/ Updating your dependencies. Go to your terminal and enter mvn clean install. Or right click on pom.xml and click Add as Mevan Project.
Check your jdk has set properly to the project.
insert the image and then backhand all you need is:
<style>
img {
border-radius: 50%;
}
</style>
** the image code will be here automatically**
If you're using Python3.x input
will return a string,so you should use int
method to convert string to integer.
If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.
By the way,it's a good way to use try
catch
if you want to convert string to int:
try:
i = int(s)
except ValueError as err:
pass
Hope this helps.
There is no difference, but you should not use either.
In many browsers, the window.onload
event is not triggered until all images have loaded, which is not what you want. Standards based browsers have an event called DOMContentLoaded
which fires earlier, but it is not supported by IE (at the time of writing this answer). I'd recommend using a javascript library which supports a cross browser DOMContentLoaded feature, or finding a well written function you can use. jQuery's $(document).ready()
, is a good example.
To add on to this:
If you're using CMAKE to generate a Visual Studio solution, and you want Visual Studio to output compiled files into /bin, Peter's answer needs to be modified a bit:
# set output directories for all builds (Debug, Release, etc.)
foreach( OUTPUTCONFIG ${CMAKE_CONFIGURATION_TYPES} )
string( TOUPPER ${OUTPUTCONFIG} OUTPUTCONFIG )
set( CMAKE_ARCHIVE_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/lib )
set( CMAKE_LIBRARY_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/lib )
set( CMAKE_RUNTIME_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/bin )
endforeach( OUTPUTCONFIG CMAKE_CONFIGURATION_TYPES )
Just to add to the answers, I think the specific reason in this case, in addition to the misplaced no-repeat
, is the space between url
and (
:
background-image: url ('/image/btn.png') no-repeat; /* Won't work */
background-image: url('/image/btn.png'); /* Should work */
The built in FTP command doesn't have a facility for security. Use cUrl instead. It's scriptable, far more robust and has FTP security.
Maybe this can help:
myArray=("$@")
also you can iterate over arguments by omitting 'in':
for arg; do
echo "$arg"
done
will be equivalent
for arg in "${myArray[@]}"; do
echo "$arg"
done
It's will definitely work.
The select option is rendered by OS not by html. That's whythe CSS style doesn't effect,.. generally
option{font-size : value ;
background-color:colorCode;
border-radius:value; }
this will work, but we can't customize the padding, margin etc..

SELECT MAX(LEN(Desc)) as MaxLen FROM table
Through the UI in SQL Server 2005 manager, change the column remove the autonumber (identity) property of the column (select the table by right clicking on it and choose "Design").
Then run your query:
UPDATE table SET Id = Id + 1
Then go and add the autonumber property back to the column.
Up to XP and Server 2003, you can make use of another included tool (VBScript) - the following two scripts do the job you want.
First, getpwd.cmd
:
@echo off
<nul: set /p passwd=Password:
for /f "delims=" %%i in ('cscript /nologo getpwd.vbs') do set passwd=%%i
echo.
Then, getpwd.vbs
:
Set oScriptPW = CreateObject("ScriptPW.Password")
strPassword = oScriptPW.GetPassword()
Wscript.StdOut.WriteLine strPassword
The getpwd.vbs
simply uses the password object to input the password from the user and then print it to standard output (the next paragraph will explain why that doesn't show up in the terminal).
The getpwd.cmd
command script is a bit trickier but it basically works as follows.
The effect of the "<nul: set /p passwd=Password: "
command is to output the prompt with no trailing newline character - it's a sneaky way to emulate the "echo -n"
command from the bash
shell. It sets passwd
to an empty string as an irrelevant side effect and doesn't wait for input since it's taking its input from the nul:
device.
The "for /f "delims=" %%i in ('cscript /nologo getpwd.vbs') do set passwd=%%i"
statement is the trickiest bit. It runs the VBScript with no Microsoft "advertising", so that the only line output is the password (from the VBscript "Wscript.StdOut.WriteLine strPassword"
.
Setting the delimiters to nothing is required to capture an entire input line with spaces, otherwise you just get the first word. The "for ... do set ..."
bit sets passwd
to be the actual password output from the VBScript.
Then we echo a blank line (to terminate the "Password: "
line) and the password will be in the passwd
environment variable after the code has run.
Now, as mentioned, scriptpw.dll
is available only up to XP/2003. In order to rectify this, you can simply copy the scriptpw.dll
file from the Windows\System32
folder of an XP/2003 system to the Winnt\System32
or Windows\System32
folder on your own system. Once the DLL has been copied, you will need to register it by running:
regsvr32 scriptpw.dll
To successfully register the DLL on Vista and later, you will need administrator privileges. I haven't examined the legality of such a move so cave lector.
If you're not overly keen on trying to track down and register older DLL files (for convenience or legal reasons), there is another way. Later versions of Windows (the ones that don't have the required DLL) should have Powershell available to you.
And, in fact, you really should consider upgrading your scripts to use it fully since it's a much more capable scripting language than cmd.exe
. However, if you want to keep the bulk of your code as cmd.exe
scripts (such as if you have a lot of code that you don't want to convert), you can use the same trick.
First, modify the cmd
script so it calls Powershell rather than CScript:
@echo off
for /f "delims=" %%i in ('powershell -file getpwd.ps1') do set passwd=%%i
The Powershell script is equally simple:
$password = Read-Host "Enter password" -AsSecureString
$password = [Runtime.InteropServices.Marshal]::SecureStringToBSTR($password)
$password = [Runtime.InteropServices.Marshal]::PtrToStringAuto($password)
echo $password
although with some marshalling to get the actual password text.
Remember that, to run local unsigned Powershell scripts on your machine, you may need to modify the execution policy from the (draconian, though very safe) default, with something like:
set-executionpolicy remotesigned
from within Powershell itself.
It depends on what you are developing.
A content-oriented website will have its content changing frequently and a Website is better for that.
An application tends to have its data stored in a database and its pages and code change rarely. In this case it's better to have a Web application where deployment of assemblies is much more controlled and has better support for unit testing.
Or you can use like this. This may be faster.
int iFindNo = 14;
int j = dataGridView1.Rows.Count-1;
int iRowIndex = -1;
for (int i = 0; i < Convert.ToInt32(dataGridView1.Rows.Count/2) +1; i++)
{
if (Convert.ToInt32(dataGridView1.Rows[i].Cells[0].Value) == iFindNo)
{
iRowIndex = i;
break;
}
if (Convert.ToInt32(dataGridView1.Rows[j].Cells[0].Value) == iFindNo)
{
iRowIndex = j;
break;
}
j--;
}
if (iRowIndex != -1)
MessageBox.Show("Index is " + iRowIndex.ToString());
else
MessageBox.Show("Index not found." );
do it the simpler way,
direc=$(basename `pwd`)
Or use the shell
$ direc=${PWD##*/}

Had same issue this end of week, only Firefox will not accept certificate... The solution for me has been to add, in the apache configuration of the website, the intermediate certificate with the following line :
SSLCACertificateFile /your/path/to/ssl_ca_certs.pem

Simply specify the directory in which the loadable extensions (modules) reside in the php.ini file from
; On windows:
extension_dir="C:\xampp\php\ext"
to
; On windows:
;extension_dir = "ext"
Then enable the extension if it was disabled by changing
;extension=mysqli
to
extension=mysqli
That's it.
You have the month and day swapped:
'%m/%d/%Y %H:%M:%S.%f'
28
will never fit in the range for the %m
month parameter otherwise.
With %m
and %d
in the correct order parsing works:
>>> from datetime import datetime
>>> datetime.strptime('07/28/2014 18:54:55.099000', '%m/%d/%Y %H:%M:%S.%f')
datetime.datetime(2014, 7, 28, 18, 54, 55, 99000)
You don't need to add '000'
; %f
can parse shorter numbers correctly:
>>> datetime.strptime('07/28/2014 18:54:55.099', '%m/%d/%Y %H:%M:%S.%f')
datetime.datetime(2014, 7, 28, 18, 54, 55, 99000)
In config/app.php file make a instance of env variable like 'name' => env('APP_NAME', 'Laravel')

php artisan cache:clear
if it is not working.
As documented in ?legend
you do this like so:
plot(1:10,type = "n")
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(1, 5, "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",box.lwd = 0,box.col = "white",bg = "white")
points(1:10,1:10)
Line breaks are achieved with the new line character \n
. Making the points still visible is done simply by changing the order of plotting. Remember that plotting in R is like drawing on a piece of paper: each thing you plot will be placed on top of whatever's currently there.
Note that the legend text is cut off because I made the plot dimensions smaller (windows.options does not exist on all R platforms).
The syntaxes
int[]
and
int[X] // Where X is a compile-time positive integer
are exactly the same as
int*
when in a function parameter list (I left out the optional names).
Additionally, an array name decays to a pointer to the first element when passed to a function (and not passed by reference) so both int firstarray[3]
and int secondarray[5]
decay to int*
s.
It also happens that both an array dereference and a pointer dereference with subscript syntax (subscript syntax is x[y]
) yield an lvalue to the same element when you use the same index.
These three rules combine to make the code legal and work how you expect; it just passes pointers to the function, along with the length of the arrays which you cannot know after the arrays decay to pointers.
If using the 'typetable reference' approach (from @Carl G) and you're using multiple type tables you might want to consider this way :
export default class AppComponent {
// Store a reference to the enums (must be public for --AOT to work)
public TT = {
CellType: CellType,
CatType: CatType,
DogType: DogType
};
...
dog = DogType.GoldenRetriever;
Then access in your html file with
{{ TT.DogType[dog] }} => "GoldenRetriever"
I favor this approach as it makes it clear you're referring to a typetable, and also avoids unnecessary pollution of your component file.
You can also put a global TT
somewhere and add enums to it as needed (if you want this you may as well make a service as shown by @VincentSels answer). If you have many many typetables this may become cumbersome.
Also you always rename them in your declaration to get a shorter name.
I've used this process to attach a 3rd party Jar to an Android project in IDEA.
The library should now be recognised.
I made an extension so now I can just load a collection with a list by doing:
MyObservableCollection.Load(MyList);
The extension is:
public static class ObservableCollectionExtension
{
public static ObservableCollection<T> Load<T>(this ObservableCollection<T> Collection, List<T> Source)
{
Collection.Clear();
Source.ForEach(x => Collection.Add(x));
return Collection;
}
}
(Mar 2017) The accepted answer is not the best solution. It relies on manual translation using Apps Script, and the code may not be resilient, requiring maintenance. If your legacy system autogenerates CSV files, it's best they go into another folder for temporary processing (importing [uploading to Google Drive & converting] to Google Sheets files).
My thought is to let the Drive API do all the heavy-lifting. The Google Drive API team released v3 at the end of 2015, and in that release, insert()
changed names to create()
so as to better reflect the file operation. There's also no more convert flag -- you just specify MIMEtypes... imagine that!
The documentation has also been improved: there's now a special guide devoted to uploads (simple, multipart, and resumable) that comes with sample code in Java, Python, PHP, C#/.NET, Ruby, JavaScript/Node.js, and iOS/Obj-C that imports CSV files into Google Sheets format as desired.
Below is one alternate Python solution for short files ("simple upload") where you don't need the apiclient.http.MediaFileUpload
class. This snippet assumes your auth code works where your service endpoint is DRIVE
with a minimum auth scope of https://www.googleapis.com/auth/drive.file
.
# filenames & MIMEtypes
DST_FILENAME = 'inventory'
SRC_FILENAME = DST_FILENAME + '.csv'
SHT_MIMETYPE = 'application/vnd.google-apps.spreadsheet'
CSV_MIMETYPE = 'text/csv'
# Import CSV file to Google Drive as a Google Sheets file
METADATA = {'name': DST_FILENAME, 'mimeType': SHT_MIMETYPE}
rsp = DRIVE.files().create(body=METADATA, media_body=SRC_FILENAME).execute()
if rsp:
print('Imported %r to %r (as %s)' % (SRC_FILENAME, DST_FILENAME, rsp['mimeType']))
Better yet, rather than uploading to My Drive
, you'd upload to one (or more) specific folder(s), meaning you'd add the parent folder ID(s) to METADATA
. (Also see the code sample on this page.) Finally, there's no native .gsheet "file" -- that file just has a link to the online Sheet, so what's above is what you want to do.
If not using Python, you can use the snippet above as pseudocode to port to your system language. Regardless, there's much less code to maintain because there's no CSV parsing. The only thing remaining is to blow away the CSV file temp folder your legacy system wrote to.
Another example:
Dim myPath As String = """" & Path.Combine(part1, part2) & """"
Good luck!
I use extention method SelfChk
static class MyExt {
//Self Check
public static void SC(this string you,ref string me)
{
me = me ?? you;
}
}
Then use like
string a = null;
"A".SC(ref a);
The short version: use formatC
or sprintf
.
The longer version:
There are several functions available for formatting numbers, including adding leading zeroes. Which one is best depends upon what other formatting you want to do.
The example from the question is quite easy since all the values have the same number of digits to begin with, so let's try a harder example of making powers of 10 width 8 too.
anim <- 25499:25504
x <- 10 ^ (0:5)
paste
(and it's variant paste0
) are often the first string manipulation functions that you come across. They aren't really designed for manipulating numbers, but they can be used for that. In the simple case where we always have to prepend a single zero, paste0
is the best solution.
paste0("0", anim)
## [1] "025499" "025500" "025501" "025502" "025503" "025504"
For the case where there are a variable number of digits in the numbers, you have to manually calculate how many zeroes to prepend, which is horrible enough that you should only do it out of morbid curiosity.
str_pad
from stringr
works similarly to paste
, making it more explicit that you want to pad things.
library(stringr)
str_pad(anim, 6, pad = "0")
## [1] "025499" "025500" "025501" "025502" "025503" "025504"
Again, it isn't really designed for use with numbers, so the harder case requires a little thinking about. We ought to just be able to say "pad with zeroes to width 8", but look at this output:
str_pad(x, 8, pad = "0")
## [1] "00000001" "00000010" "00000100" "00001000" "00010000" "0001e+05"
You need to set the scientific penalty option so that numbers are always formatted using fixed notation (rather than scientific notation).
library(withr)
with_options(
c(scipen = 999),
str_pad(x, 8, pad = "0")
)
## [1] "00000001" "00000010" "00000100" "00001000" "00010000" "00100000"
stri_pad
in stringi
works exactly like str_pad
from stringr
.
formatC
is an interface to the C function printf
. Using it requires some knowledge of the arcana of that underlying function (see link). In this case, the important points are the width
argument, format
being "d"
for "integer", and a "0"
flag
for prepending zeroes.
formatC(anim, width = 6, format = "d", flag = "0")
## [1] "025499" "025500" "025501" "025502" "025503" "025504"
formatC(x, width = 8, format = "d", flag = "0")
## [1] "00000001" "00000010" "00000100" "00001000" "00010000" "00100000"
This is my favourite solution, since it is easy to tinker with changing the width, and the function is powerful enough to make other formatting changes.
sprintf
is an interface to the C function of the same name; like formatC
but with a different syntax.
sprintf("%06d", anim)
## [1] "025499" "025500" "025501" "025502" "025503" "025504"
sprintf("%08d", x)
## [1] "00000001" "00000010" "00000100" "00001000" "00010000" "00100000"
The main advantage of sprintf
is that you can embed formatted numbers inside longer bits of text.
sprintf(
"Animal ID %06d was a %s.",
anim,
sample(c("lion", "tiger"), length(anim), replace = TRUE)
)
## [1] "Animal ID 025499 was a tiger." "Animal ID 025500 was a tiger."
## [3] "Animal ID 025501 was a lion." "Animal ID 025502 was a tiger."
## [5] "Animal ID 025503 was a tiger." "Animal ID 025504 was a lion."
See also goodside's answer.
For completeness it is worth mentioning the other formatting functions that are occasionally useful, but have no method of prepending zeroes.
format
, a generic function for formatting any kind of object, with a method for numbers. It works a little bit like formatC
, but with yet another interface.
prettyNum
is yet another formatting function, mostly for creating manual axis tick labels. It works particularly well for wide ranges of numbers.
The scales
package has several functions such as percent
, date_format
and dollar
for specialist format types.
You are using the wrong parameters name, try:
if($_POST){
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['text'];
//send email
mail("[email protected]", "51 Deep comment from" .$email, $message);
}
You can use this:
function same(a) {
if (!a.length) return true;
return !a.filter(function (e) {
return e !== a[0];
}).length;
}
The function first checks whether the array is empty. If it is it's values are equals.. Otherwise it filter the array and takes all elements which are different from the first one. If there are no such values => the array contains only equal elements otherwise it doesn't.
In 2015, there are at least six choices for JavaScript debugging in Eclipse:
Adding to the above, here are a couple of videos which focus on "debugging JavaScript using eclipse"
A quick answer, that doesn't require you to edit any configuration files (and works on other operating systems as well as Windows), is to just find the directory that you are allowed to save to using:
mysql> SHOW VARIABLES LIKE "secure_file_priv";
+------------------+-----------------------+
| Variable_name | Value |
+------------------+-----------------------+
| secure_file_priv | /var/lib/mysql-files/ |
+------------------+-----------------------+
1 row in set (0.06 sec)
And then make sure you use that directory in your SELECT
statement's INTO OUTFILE
clause:
SELECT *
FROM xxxx
WHERE XXX
INTO OUTFILE '/var/lib/mysql-files/report.csv'
FIELDS TERMINATED BY '#'
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
Original answer
I've had the same problem since upgrading from MySQL 5.6.25 to 5.6.26.
In my case (on Windows), looking at the MySQL56 Windows service shows me that the options/settings file that is being used when the service starts is C:\ProgramData\MySQL\MySQL Server 5.6\my.ini
On linux the two most common locations are /etc/my.cnf
or /etc/mysql/my.cnf
.
Opening this file I can see that the secure-file-priv
option has been added under the [mysqld]
group in this new version of MySQL Server with a default value:
secure-file-priv="C:/ProgramData/MySQL/MySQL Server 5.6/Uploads"
You could comment this (if you're in a non-production environment), or experiment with changing the setting (recently I had to set secure-file-priv = ""
in order to disable the default). Don't forget to restart the service after making changes.
Alternatively, you could try saving your output into the permitted folder (the location may vary depending on your installation):
SELECT *
FROM xxxx
WHERE XXX
INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 5.6/Uploads/report.csv'
FIELDS TERMINATED BY '#'
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
It's more common to have comma seperate values using FIELDS TERMINATED BY ','
. See below for an example (also showing a Linux path):
SELECT *
FROM table
INTO OUTFILE '/var/lib/mysql-files/report.csv'
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
ESCAPED BY ''
LINES TERMINATED BY '\n';
Why not change the constructor on Production
to let you pass in a reference at construction time:
public class Meter
{
private int _powerRating = 0;
private Production _production;
public Meter()
{
_production = new Production(this);
}
}
In the Production
constructor you can assign this to a private field or a property. Then Production
will always have access to is parent.
DataContractJsonSerializer serializer =
new DataContractJsonSerializer(typeof(YourObjectType));
YourObjectType yourObject = (YourObjectType)serializer.ReadObject(jsonStream);
You could also use the JavaScriptSerializer
, but DataContractJsonSerializer
is supposedly better able to handle complex types.
Oddly enough JavaScriptSerializer was once deprecated (in 3.5) and then resurrected because of ASP.NET MVC (in 3.5 SP1). That would definitely be enough to shake my confidence and lead me to use DataContractJsonSerializer
since it is hard baked for WCF.
My approach was similar to @SoftwareFactor, but different, perhaps because I'm running a different OS, Windows Server 2012. These steps worked for me.

The way I understand it is, that tightly coupled architecture does not provide a lot of flexibility for change when compared to loosely coupled architecture.
But in case of loosely coupled architectures, message formats or operating platforms or revamping the business logic does not impact the other end. If the system is taken down for a revamp, of course the other end will not be able to access the service for a while but other than that, the unchanged end can resume message exchange as it was before the revamp.
In order to append to a file you'll need to use a slightly different approach. You can still redirect an individual process' standard error and standard output to a file, but in order to append it to a file you'll need to do one of these things:
Start-Process
&
The first way would look like this:
$myLog = "C:\File.log"
$stdErrLog = "C:\stderr.log"
$stdOutLog = "C:\stdout.log"
Start-Process -File myjob.bat -RedirectStandardOutput $stdOutLog -RedirectStandardError $stdErrLog -wait
Get-Content $stdErrLog, $stdOutLog | Out-File $myLog -Append
The second way would look like this:
& myjob.bat 2>&1 >> C:\MyLog.txt
Or this:
& myjob.bat 2>&1 | Out-File C:\MyLog.txt -Append
The third way:
$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.FileName = "myjob.bat"
$pinfo.RedirectStandardError = $true
$pinfo.RedirectStandardOutput = $true
$pinfo.UseShellExecute = $false
$pinfo.Arguments = ""
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start() | Out-Null
$p.WaitForExit()
$output = $p.StandardOutput.ReadToEnd()
$output += $p.StandardError.ReadToEnd()
$output | Out-File $myLog -Append
String[] command = {"cmd.exe" , "/c", "start" , "cmd.exe" , "/k" , "\" dir && ipconfig
\"" };
ProcessBuilder probuilder = new ProcessBuilder( command );
probuilder.directory(new File("D:\\Folder1"));
Process process = probuilder.start();
HTML5 defines an oninput
event to catch all direct changes. it works for me.
Ok, here's a ready-to-copy-paste answer using the require('request') npm module and an environment variable *instead of an hardcoded proxy):
coffeescript
app.use (req, res, next) ->
r = false
method = req.method.toLowerCase().replace(/delete/, 'del')
switch method
when 'get', 'post', 'del', 'put'
r = request[method](
uri: process.env.PROXY_URL + req.url
json: req.body)
else
return res.send('invalid method')
req.pipe(r).pipe res
javascript:
app.use(function(req, res, next) {
var method, r;
method = req.method.toLowerCase().replace(/delete/,"del");
switch (method) {
case "get":
case "post":
case "del":
case "put":
r = request[method]({
uri: process.env.PROXY_URL + req.url,
json: req.body
});
break;
default:
return res.send("invalid method");
}
return req.pipe(r).pipe(res);
});
In SQL Server 2014 Management Studio the setting is at:
Tools > Options > Query Results > SQL Server > Results to Text > Include column headers in the result set.
Try this more succinct code:
Sub LoopOverEachColumn()
Dim WS As Worksheet
For Each WS In ThisWorkbook.Worksheets
ResizeColumns WS
Next WS
End Sub
Private Sub ResizeColumns(WS As Worksheet)
Dim StrSize As String
Dim ColIter As Long
StrSize = "20.14;9.71;35.86;30.57;23.57;21.43;18.43;23.86;27.43;36.71;30.29;31.14;31;41.14;33.86"
For ColIter = 1 To 15
WS.Columns(ColIter).ColumnWidth = Split(StrSize, ";")(ColIter - 1)
Next ColIter
End Sub
If you want additional columns, just change 1 to 15
to 1 to X
where X
is the column index of the column you want, and append the column size you want to StrSize
.
For example, if you want P:P
to have a width of 25
, just add ;25
to StrSize
and change ColIter...
to ColIter = 1 to 16
.
Hope this helps.

You can create a materialized/indexed views on the table. Based on your requirement you can do full or partial update of the views. Please see this to create mview and log. How to create materialized views in SQL Server?
This answer is not working since the urllib2
module has been split across several modules in Python 3.
You need to do
from urllib import request
opener = request.build_opener()
opener.addheaders.append(('Cookie', 'cookiename=cookievalue'))
f = opener.open("http://example.com/")
JSONObject json = new JSONObject();
json.put("fromZIPCode","123456");
JSONObject json1 = new JSONObject();
json1.put("fromZIPCode","123456");
sList.add(json1);
sList.add(json);
System.out.println(sList);
Output will be
[{"fromZIPCode":"123456"},{"fromZIPCode":"123456"}]
You can also enter a very large number, and then press dd
if you wish to delete all the lines below the cursor.
Try to play with
setMinSize()

What bout this query (based on the description from manual)?
SELECT table_name
FROM information_schema.tables
WHERE table_schema='public'
AND table_type='BASE TABLE';
you can use the simpleDateFormat to parse the string date.
Add this to your XML layout:
android:ellipsize="marquee"
android:focusable="false"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="To Make An textView Scrollable Inside The TextView Using Marquee"
And in code you have to write the following lines:
textview.setSelected(true);
textView.setMovementMethod(new ScrollingMovementMethod());
The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.
To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".
To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".
Explanation:
From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):
4.3.8 ‘Local echo’
With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)
Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.
4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.
If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.
Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)
Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.
Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

It's very simple, and I'm just beginning, but it worked quite nicely
I use open query to perform this task like so:
select top 1 *
INTO [DATABASE_TO_INSERT_INTO].[dbo].[TABLE_TO_SELECT_INTO]
from openquery(
[LINKED_SERVER_NAME],
'select * from [DATABASE_ON_LINKED_SERVER].[dbo].[TABLE_TO_SELECT_FROM]'
)
The example above uses open query to select data from a database on a linked server into a database of your choosing.
Note: For completeness of reference, you may perform a simple select like so:
select top 1 * from openquery(
[LINKED_SERVER_NAME],
'select * from [DATABASE_ON_LINKED_SERVER].[dbo].[TABLE_TO_SELECT_FROM]'
)
If you are already in an Angular project you could use $filter('date')
.
For example:
var myDate = new Date();
var myWeek = $filter('date')(myDate, 'ww');

Hi used this thread to get the solution , then i would like to share what i did just in case someone could use it.
What i wanted was to call a macro that change some cells and erase some rows, but i needed for more than 1500 excels( approximately spent 3 minuts for each file)
Mainly problem: -when calling the macro from vbe , i got the same problem, it was imposible to call the macro from PERSONAL.XLSB, when the script oppened the excel didnt execute personal.xlsb and wasnt any option in the macro window
I solved this by keeping open one excel file with the macro loaded(a.xlsm)(before executing the script)
Then i call the macro from the excel oppened by the script
Option Explicit
Dim xl
Dim counter
counter =10
Do
counter = counter + 1
Set xl = GetObject(, "Excel.Application")
xl.Application.Workbooks.open "C:\pruebas\macroxavi\IA_030-08-026" & counter & ".xlsx"
xl.Application.Visible = True
xl.Application.run "'a.xlsm'!eraserow"
Set xl = Nothing
Loop Until counter = 517
WScript.Echo "Finished."
WScript.Quit
Another simple solution is to create a filter:
app.filter('trusted', ['$sce', function ($sce) {
return function(url) {
return $sce.trustAsResourceUrl(url);
};
}]);
Then specify the filter in ng-src
:
<video controls poster="img/poster.png">
<source ng-src="{{object.src | trusted}}" type="video/mp4"/>
</video>
You don't set value to default in a table. You should clear the option "Default value or Binding" first.
It's HTML character references for encoding a character by its decimal code point
Look at the ASCII table here and you'll see that 39 (hex 0x27, octal 47) is the code for apostrophe
Since you're returning a string as JSON, that string will include the opening and closing quotes in the raw response. So your response should probably look like:
"abc123XYZ=="
or whatever...You can try confirming this with Fiddler.
My guess is that the result.Content
is the raw string, including the quotes. If that's the case, then result.Content
will need to be deserialized before you can use it.
Learning C forces you to think harder about some issues such as explicit and implicit memory management or storage sizes of basic data types at the time you write your code.
Once you have reached a point where you feel comfortable around C's features and misfeatures, you will probably have less trouble learning and writing in C++.
It is entirely possible that the C++ code you have seen did not look much different from standard C, but that may well be because it was not object oriented and did not use exceptions, object-orientation, templates or other advanced features.

You can pass the value to the function using this.value
, where this
points to the button
<input type="button" value="mybutton1" onclick="dosomething(this.value)">
And then access that value in the function
function dosomething(val){
console.log(val);
}
When you append to the div, hide it and show it with the argument "slow"
.
$("#img_container").append(first_div).hide().show('slow');
Getting last nth months data retrieve
SELECT * FROM TABLE_NAME
WHERE DATE_COLUMN BETWEEN '&STARTDATE' AND '&ENDDATE';
To concat files in command prompt it would be
type file1.txt file2.txt file3.txt > files.txt
PowerShell converts the type
command to Get-Content
, which means you will get an error when using the type
command in PowerShell because the Get-Content
command requires a comma separating the files. The same command in PowerShell would be
Get-Content file1.txt,file2.txt,file3.txt | Set-Content files.txt
$shortClassName = join('',array_slice(explode('\\', $longClassName), -1));
After 7 years... the facelets solution still works fine for me as a jsf user
include the namespace as
xmlns:fn="http://java.sun.com/jsp/jstl/functions"
and use the EL as
#{fn:length(myBean.someList)}
for example if using in jsf ui:fragment below example works fine
<ui:fragment rendered="#{fn:length(myBean.someList) gt 0}">
<!-- Do something here-->
</ui:fragment>
All objects in JavaScript are implemented as hashtables/associative arrays. So, the following are the equivalent:
alert(myObj["SomeProperty"]);
alert(myObj.SomeProperty);
And, as already indicated, you "remove" a property from an object via the delete
keyword, which you can use in two ways:
delete myObj["SomeProperty"];
delete myObj.SomeProperty;
Hope the extra info helps...
This is one of de best, simplest and most efficient ways to do it. You can convert arrays to tables with any number of columns or rows. It takes the array keys as table header. No need of array_map.
function array_to_table($matriz)
{
echo "<table>";
// Table header
foreach ($matriz[0] as $clave=>$fila) {
echo "<th>".$clave."</th>";
}
// Table body
foreach ($matriz as $fila) {
echo "<tr>";
foreach ($fila as $elemento) {
echo "<td>".$elemento."</td>";
}
echo "</tr>";
}
echo "</table>";}

Ok I have found a solution. The problem is that the site uses SSLv3. And I know that there are some problems in the openssl module. Some time ago I had the same problem with the SSL versions.
<?php
function getSSLPage($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSLVERSION,3);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
var_dump(getSSLPage("https://eresearch.fidelity.com/eresearch/evaluate/analystsOpinionsReport.jhtml?symbols=api"));
?>
When you set the SSL Version with curl to v3 then it works.
Edit:
Another problem under Windows is that you don't have access to the certificates. So put the root certificates directly to curl.
http://curl.haxx.se/docs/caextract.html
here you can download the root certificates.
curl_setopt($ch, CURLOPT_CAINFO, __DIR__ . "/certs/cacert.pem");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
Then you can use the CURLOPT_SSL_VERIFYPEER
option with true
otherwise you get an error.
NullPointerException
s are exceptions that occur when you try to use a reference that points to no location in memory (null) as though it were referencing an object. Calling a method on a null reference or trying to access a field of a null reference will trigger a NullPointerException
. These are the most common, but other ways are listed on the NullPointerException
javadoc page.
Probably the quickest example code I could come up with to illustrate a NullPointerException
would be:
public class Example {
public static void main(String[] args) {
Object obj = null;
obj.hashCode();
}
}
On the first line inside main
, I'm explicitly setting the Object
reference obj
equal to null
. This means I have a reference, but it isn't pointing to any object. After that, I try to treat the reference as though it points to an object by calling a method on it. This results in a NullPointerException
because there is no code to execute in the location that the reference is pointing.
(This is a technicality, but I think it bears mentioning: A reference that points to null isn't the same as a C pointer that points to an invalid memory location. A null pointer is literally not pointing anywhere, which is subtly different than pointing to a location that happens to be invalid.)
My reason for sometimes preferring Timer over Executors.newSingleThreadScheduledExecutor() is that I get much cleaner code when I need the timer to execute on daemon threads.
compare
private final ThreadFactory threadFactory = new ThreadFactory() {
public Thread newThread(Runnable r) {
Thread t = new Thread(r);
t.setDaemon(true);
return t;
}
};
private final ScheduledExecutorService timer = Executors.newSingleThreadScheduledExecutor(threadFactory);
with
private final Timer timer = new Timer(true);
I do this when I don't need the robustness of an executorservice.
The short answer is: never!
There's now a much easier way to install an older version of a formula that you'd previously installed. Simply use
brew switch [formula] [version]
For instance, I alternate regularly between Node.js 0.4.12 and 0.6.5:
brew switch node 0.4.12
brew switch node 0.6.5
Since brew switch
just changes the symlinks, it's very fast. See further documentation on the Homebrew Wiki under External Commands.
It works with Android Studio 1.2 + OpenCV-2.4.11-android-sdk (.zip), too.
Just do the following:
1) Follow the answer that starts with "You can do this very easily in Android Studio. Follow the steps below to add OpenCV in your project as library." by TGMCians.
2) Modify in the <yourAppDir>\libraries\opencv
folder your newly created build.gradle
to (step 4 in TGMCians' answer, adapted to OpenCV2.4.11-android-sdk and using gradle 1.1.0):
apply plugin: 'android-library'
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.0'
}
}
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
minSdkVersion 8
targetSdkVersion 21
versionCode 2411
versionName "2.4.11"
}
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
res.srcDirs = ['res']
aidl.srcDirs = ['src']
}
}
}
3) *.so files that are located in the directories "armeabi", "armeabi-v7a", "mips", "x86"
can be found under (default OpenCV-location): ..\OpenCV-2.4.11-android-sdk\OpenCV-android-sdk\sdk\native\libs
(step 9 in TGMCians' answer).
Enjoy and if this helped, please give a positive reputation. I need 50 to answer directly to answers (19 left) :)
To set a values above or below the range of the colormap, you'll want to use the set_over
and set_under
methods of the colormap. If you want to flag a particular value, mask it (i.e. create a masked array), and use the set_bad
method. (Have a look at the documentation for the base colormap class: http://matplotlib.org/api/colors_api.html#matplotlib.colors.Colormap )
It sounds like you want something like this:
import matplotlib.pyplot as plt
import numpy as np
# Generate some data
x, y, z = np.random.random((3, 30))
z = z * 20 + 0.1
# Set some values in z to 0...
z[:5] = 0
cmap = plt.get_cmap('jet', 20)
cmap.set_under('gray')
fig, ax = plt.subplots()
cax = ax.scatter(x, y, c=z, s=100, cmap=cmap, vmin=0.1, vmax=z.max())
fig.colorbar(cax, extend='min')
plt.show()
This originally answered a supplemental question about the wisdom of downloading jQuery versus accessing it via a CDN, which is no longer present...
To answer the thing about Google. I have moved over to accessing JQuery and most other of these sorts of libraries via the corresponding CDN in my sites.
As more people do this means that it's more likely to be cached on user's machines, so my vote goes for good idea.
In the five years since I first offered this, it has become common wisdom.
The top answer is useful but I expanded on it a bit.
If you want to set the value of your file object (the f
in as f
) based on the arguments passed to open()
here's one way to do it:
def save_arg_return_data(*args, **kwargs):
mm = MagicMock(spec=file)
mm.__enter__.return_value = do_something_with_data(*args, **kwargs)
return mm
m = MagicMock()
m.side_effect = save_arg_return_array_of_data
# if your open() call is in the file mymodule.animals
# use mymodule.animals as name_of_called_file
open_name = '%s.open' % name_of_called_file
with patch(open_name, m, create=True):
#do testing here
Basically, open()
will return an object and with
will call __enter__()
on that object.
To mock properly, we must mock open()
to return a mock object. That mock object should then mock the __enter__()
call on it (MagicMock
will do this for us) to return the mock data/file object we want (hence mm.__enter__.return_value
). Doing this with 2 mocks the way above allows us to capture the arguments passed to open()
and pass them to our do_something_with_data
method.
I passed an entire mock file as a string to open()
and my do_something_with_data
looked like this:
def do_something_with_data(*args, **kwargs):
return args[0].split("\n")
This transforms the string into a list so you can do the following as you would with a normal file:
for line in file:
#do action
By using (array) and (object) as prefix, you can simply convert object array to standard array and vice-verse
<?php
//defining an array
$a = array('a'=>'1','b'=>'2','c'=>'3','d'=>'4');
//defining an object array
$obj = new stdClass();
$obj->a = '1';
$obj->b = '2';
$obj->c = '3';
$obj->d = '4';
print_r($a);echo '<br>';
print_r($obj);echo '<br>';
//converting object array to array
$b = (array) $obj;
print_r($b);echo '<br>';
//converting array to object
$c = (object) $a;
print_r($c);echo '<br>';
?>
Array.prototype.toString()
The toString() method returns a string representing the specified array and its elements.
var months = ["Jan", "Feb", "Mar", "Apr"]; months.toString(); // "Jan,Feb,Mar,Apr"
Syntax
arr.toString()
Return value
A string representing the elements of the array.

You can also solve this problem by doing a:
rm -rf <tomcat-dir>/work/* <tomcat-dir>/temp/*
Clearing out the work and temp directories makes Tomcat do a clean startup.
Import connect
from react-redux
and use it to connect the component with the state connect(mapStates,mapDispatch)(component)
import React from "react";
import { connect } from "react-redux";
const MyComponent = (props) => {
return (
<div>
<h1>{props.title}</h1>
</div>
);
}
}
Finally you need to map the states to the props to access them with this.props
const mapStateToProps = state => {
return {
title: state.title
};
};
export default connect(mapStateToProps)(MyComponent);
Only the states that you map will be accessible via props

use coalesce
COALESCE(value [, ...])
The COALESCE function returns the first of its arguments that is not null. Null is returned only if all arguments are null. It is often used to substitute a default value for null values when data is retrieved for display.
Edit
Here's an example of COALESCE
with your query:
SELECT AVG( price )
FROM(
SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
WHERE listing_Type = 'AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
AND COALESCE( price, 0 ) > ( SELECT AVG( COALESCE( price, 0 ) )* 0.50
FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
FROM web_price_scan
WHERE listing_Type='AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
) g
WHERE cume_dist < 0.50
)
AND COALESCE( price, 0 ) < ( SELECT AVG( COALESCE( price, 0 ) ) *2
FROM( SELECT *, cume_dist() OVER ( ORDER BY price desc )
FROM web_price_scan
WHERE listing_Type='AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
) d
WHERE cume_dist < 0.50)
)s
HAVING COUNT(*) > 5
IMHO COALESCE
should not be use with AVG
because it modifies the value. NULL
means unknown and nothing else. It's not like using it in SUM
. In this example, if we replace AVG
by SUM
, the result is not distorted. Adding 0 to a sum doesn't hurt anyone but calculating an average with 0 for the unknown values, you don't get the real average.
In that case, I would add price IS NOT NULL
in WHERE
clause to avoid these unknown values.

As far I think I understood your question I believe that u can simply declare your variable inside "DECLARE" and then after the "begin" u can use 'select into " you variable" ' statement. the code would look like this:

select ID into YourVar from table
where ...

Well, I just did
brew install mongodb
and followed the instructions that were output to the STDOUT
after it finished installing, and that seems to have worked just fine. I guess it kinda works just like make install
and overwrites (upgrades) a previous install.

Here's some examples that demonstrate setting and detecting timeouts in jQuery's old and new paradigmes.
Promise with jQuery 1.8+
Promise.resolve(
$.ajax({
url: '/getData',
timeout:3000 //3 second timeout
})
).then(function(){
//do something
}).catch(function(e) {
if(e.statusText == 'timeout')
{
alert('Native Promise: Failed from timeout');
//do something. Try again perhaps?
}
});
jQuery 1.8+
$.ajax({
url: '/getData',
timeout:3000 //3 second timeout
}).done(function(){
//do something
}).fail(function(jqXHR, textStatus){
if(textStatus === 'timeout')
{
alert('Failed from timeout');
//do something. Try again perhaps?
}
});?
jQuery <= 1.7.2
$.ajax({
url: '/getData',
error: function(jqXHR, textStatus){
if(textStatus === 'timeout')
{
alert('Failed from timeout');
//do something. Try again perhaps?
}
},
success: function(){
//do something
},
timeout:3000 //3 second timeout
});
Notice that the textStatus param (or jqXHR.statusText) will let you know what the error was. This may be useful if you want to know that the failure was caused by a timeout.
error(jqXHR, textStatus, errorThrown)
A function to be called if the request fails. The function receives three arguments: The jqXHR (in jQuery 1.4.x, XMLHttpRequest) object, a string describing the type of error that occurred and an optional exception object, if one occurred. Possible values for the second argument (besides null) are "timeout", "error", "abort", and "parsererror". When an HTTP error occurs, errorThrown receives the textual portion of the HTTP status, such as "Not Found" or "Internal Server Error." As of jQuery 1.5, the error setting can accept an array of functions. Each function will be called in turn. Note: This handler is not called for cross-domain script and JSONP requests.
Opaque responses can't be accessed by JavaScript, but you can still cache them with the Cache API and respond with them in the fetch
event handler in a service worker. So they're useful for making your app offline, also for resources that you can't control (e.g. resources on a CDN that doesn't set the CORS headers).
Change the code where you load the partial view to:
@Html.Partial("_CreateNote", new QuickNotes.Models.Note())
This is because the partial view is expecting a Note but is getting passed the model of the parent view which is the IEnumerable
As has been noted the perfect regex is elusive but still seems to be a reasonable approach (alternatives are server side tests or the new experimental URL API). However the high ranking answers are often returning false for common URLs but even worse will freeze your app/page for minutes on even as simple a string as isURL('aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa')
. It's been pointed out in some of the comments, but most probably haven't entered a bad value to see it. Hanging like that makes that code unusable in any serious application. I think it's due to the repeated case insensitive sets in code like ((([a-z\\d]([a-z\\d-]*[a-z\\d])*)\\.?)+[a-z]{2,}|' ...
. Take out the 'i' and it doesn't hang but will of course not work as desired. But even with the ignore case flag those tests reject high unicode values that are allowed.
The best already mentioned is:
function isURL(str) {
return /^(?:\w+:)?\/\/([^\s\.]+\.\S{2}|localhost[\:?\d]*)\S*$/.test(str);
}
That comes from Github segmentio/is-url. The good thing about a code repository is you can see the testing and any issues and also the test strings run through it. There's a branch that would allow strings missing protocol like google.com
, though you're probably making too many assumptions then. The repository has been updated and I'm not planning on trying to keep up a mirror here. It's been broken up into separate tests to avoid RegEx redos which can be exploited for DOS attacks (I don't think you have to worry about that with client side js, but you do have to worry about your page hanging for so long that your visitor leaves your site).
There is one other repository I've seen that may even be better for isURL at dperini/regex-weburl.js, but it is highly complex. It has a bigger test list of valid and invalid URLs. The simple one above still passes all the positives and only fails to block a few odd negatives like http://a.b--c.de/
as well as the special ips.
Whichever you choose, run it through this function which I've adapted from the tests on dperini/regex-weburl.js, while using your browser's Developer Tools inpector.

patrick dw's answer is right on.
For kicks and giggles I thought I would post a simple way to return an array of all the IDs.
var arrayOfIds = $.map($(".myClassName"), function(n, i){
return n.id;
});
alert(arrayOfIds);
PHP is a normal sripting language similar to bash or python or perl. So a script with shebang works, at least on linux.
Example PHP file:
#!/usr/bin/env php
<?php
echo("Hello World!\n")
?>
How to run it:
$ chmod 755 hello.php # do this only once
$ ./hello.php
[+*?.] Most special characters have no meaning inside the square brackets. This expression matches any of +, *, ? or the dot.
Tail Recursion is pretty fast as compared to normal recursion. It is fast because the output of the ancestors call will not be written in stack to keep the track. But in normal recursion all the ancestor calls output written in stack to keep the track.
It might also be worth mentioning that inline will try to open Office Documents (xls, doc etc) directly from the server, which might lead to a User Credentials Prompt.

In my case I had to make a POST request, which had information sent through the header, and also a file sent using a FormData object.
I made it work using a combination of some of the answers here, so basically what ended up working was having this five lines in my Ajax request:
contentType: "application/octet-stream",
enctype: 'multipart/form-data',
contentType: false,
processData: false,
data: formData,
Where formData was a variable created like this:
var file = document.getElementById('uploadedFile').files[0];
var form = $('form')[0];
var formData = new FormData(form);
formData.append("File", file);
using Microsoft.Win32;

You want \s
Matches a single white space character, including space, tab, form feed, line feed.
Equivalent to
[ \f\n\r\t\v\u00a0\u1680\u2000-\u200a\u2028\u2029\u202f\u205f\u3000\ufeff]
in Firefox and [ \f\n\r\t\v]
in IE.
str = str.replace(/\s/g, "X");
Dirty trick: You could as well use lambda expression to pass any code you want including the call with parameters.
this.Include(includes, () =>
{
_context.Cars.Include(<parameters>);
});
This can happen if your application is in a virtual directory and the path to the files is a mapped drive.
If you change the path to the files to a local drive, this will solve it, if that indeed is your problem.
Yes: You can use Inner Join
to join on multiple columns.
SELECT E.CaseNum, E.FileNum, E.ActivityNum, E.Grade, V.Score from Evaluation E
INNER JOIN Value V
ON E.CaseNum = V.CaseNum AND
E.FileNum = V.FileNum AND
E.ActivityNum = V.ActivityNum
Create table
CREATE TABLE MyNewTab(CaseNum int, FileNum int,
ActivityNum int, Grade int, Score varchar(100))
Insert values
INSERT INTO MyNewTab Values(CaseNum, FileNum, ActivityNum, Grade, Score)
SELECT E.CaseNum, E.FileNum, E.ActivityNum, E.Grade, V.Score from Evaluation E
INNER JOIN Value V
ON E.CaseNum = V.CaseNum AND
E.FileNum = V.FileNum AND
E.ActivityNum = V.ActivityNum
you can initialize it to ' ' instead. Also, the reason that you received an error -1 being too many characters is because it is treating '-' and 1 as separate.
TL;DR: add the parameter cursorclass=MySQLdb.cursors.DictCursor
at the end of your MySQLdb.connect
.
I had a working code and the DB moved, I had to change the host/user/pass. After this change, my code stopped working and I started getting this error. Upon closer inspection, I copy-pasted the connection string on a place that had an extra directive. The old code read like:
conn = MySQLdb.connect(host="oldhost",
user="olduser",
passwd="oldpass",
db="olddb",
cursorclass=MySQLdb.cursors.DictCursor)
Which was replaced by:
conn = MySQLdb.connect(host="newhost",
user="newuser",
passwd="newpass",
db="newdb")
The parameter cursorclass=MySQLdb.cursors.DictCursor
at the end was making python allow me to access the rows using the column names as index. But the poor copy-paste eliminated that, yielding the error.
So, as an alternative to the solutions already presented, you can also add this parameter and access the rows in the way you originally wanted. ^_^ I hope this helps others.
Kotlin version with how much percent do you want to match.
Method call with percent optional argument
isMatchingColor(intColor1, intColor2, 95) // should match color if 95% similar
Method body

val threadSold = 255 - (255 / 100f * percent)
val diffAlpha = abs(Color.alpha(intColor1) - Color.alpha(intColor2))
val diffRed = abs(Color.red(intColor1) - Color.red(intColor2))
val diffGreen = abs(Color.green(intColor1) - Color.green(intColor2))

If you want all the bars to get the same color (fill
), you can easily add it inside geom_bar
.
ggplot(data=df, aes(x=c1+c2/2, y=c3)) +
geom_bar(stat="identity", width=c2, fill = "#FF6666")
Add fill = the_name_of_your_var
inside aes
to change the colors depending of the variable :
c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) +
geom_bar(stat="identity", width=c2)
Use scale_fill_manual()
if you want to manually the change of colors.
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) +
geom_bar(stat="identity", width=c2) +
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))
list = ["my", "name", "is", "kourosh"]
" ".join(list)
If this is an input, using the JOIN method, we can add the distance between the words and also convert the list to the string.
This is Python output
'my name is kourosh'
That's an old thread, but in case you want to upload the image having same extension-
$image = $request->image;
$imageInfo = explode(";base64,", $image);
$imgExt = str_replace('data:image/', '', $imageInfo[0]);
$image = str_replace(' ', '+', $imageInfo[1]);
$imageName = "post-".time().".".$imgExt;
Storage::disk('public_feeds')->put($imageName, base64_decode($image));
You can create 'public_feeds' in laravel's filesystem.php-
'public_feeds' => [
'driver' => 'local',
'root' => public_path() . '/uploads/feeds',
],
I am pretty sure that those volumes are actually mounted on your system. Look in /proc/mounts and you will see them there. You will likely need to sudo umount <path>
or sudo umount -f -n <path>
. You should be able to get the mounted path either in /proc/mounts or through docker volume inspect
From the docs:
_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.
So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.
Edit: Further reading led me here:
http://www.analyticsmarket.com/blog/edit-ecommerce-data
Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.

Giving out the longest files first (ie. maybe these long files need some refactoring love?), and excluding some vendor directories:
find . -name '*.php' | xargs wc -l | sort -nr | egrep -v "libs|tmp|tests|vendor" | less
Not a direct answer to the OP's question, but in my case, I had the following setup -
Typescript - v3.6.2
tslint - v5.20.0
And using the following code
const refToElement = useRef(null);
if (refToElement && refToElement.current) {
refToElement.current.focus(); // Object is possibly 'null' (for refToElement.current)
}
I moved on by suppressing the compiler for that line. Note that since it's a compiler error and not the linter error, // tslint:disable-next-line
didn't work. Also, as per the documentation, this should be used rarely, only when necessary -
const refToElement = useRef(null);
if (refToElement && refToElement.current) {
// @ts-ignore: Object is possibly 'null'.
refToElement.current.focus();
}
UPDATE :
With Typescript 3.7, you can use optional chaining, to solve the above problem as -
refToElement?.current?.focus();
Always you can do it manually. Those are the steps:
git clone github_url
node_modules
folder for e.g. node_modules/browser-sync
Now it should work for you. To be sure it will not break in the future when you do npm i
, continue the upcoming two steps:
package.json
file in it's folder.package.json
and set the same version for where it's appear in the dependencies
part of your package.json
While it's not recommened to do it manually. Sometimes it's good to understand how things are working under the hood, to be able to fix things. I found myself doing it from time to time.
I got it work by overriding annotation with XML file for Postgres. Annotation is kept for Oracle. In my opinion, in this case it would be best we override the mapping of this trouble-some enity with xml mapping. We can override single / multiple entities with xml mapping. So we would use annotation for our mainly-supported database, and a xml file for each other database.
Note: we just need to override one single class , so it is not a big deal. Read more from my example Example to override annotation with XML
The largest number that can be represented by an n digit number in base b is bn - 1. Hence, the largest number that can be represented in N binary digits is 2N - 1. We need the smallest integer N such that:
2N - 1 = bn - 1
? 2N = bn
Taking the base 2 logarithm of both sides of the last expression gives:
log2 2N = log2 bn
? N = log2 bn
? N = log bn / log 2
Since we want the smallest integer N that satisfies the last relation, to find N, find log bn / log 2 and take the ceiling.
In the last expression, any base is fine for the logarithms, so long as both bases are the same. It is convenient here, since we are interested in the case where b = 10, to use base 10 logarithms taking advantage of log1010n == n.
For n = 3:
N = ?3 / log10 2? = 10
For n = 4:
N = ?4 / log10 2? = 14
For n = 6:
N = ?6 / log10 2? = 20
And in general, for n decimal digits:
N = ?n / log10 2?
Starting in Python 3.7, you can use the breakpoint()
built-in function to enter the debugger:
foo()
breakpoint() # drop into the debugger at this point
bar()
By default, breakpoint()
will import pdb
and call pdb.set_trace()
. However, you can control debugging behavior via sys.breakpointhook()
and use of the environment variable PYTHONBREAKPOINT
.
See PEP 553 for more information.

You cannot add methods to an existing type unless the existing type is marked as partial, you can only add methods that appear to be a member of the existing type through extension methods. Since this is the case you cannot add static methods to the type itself since extension methods use instances of that type.
There is nothing stopping you from creating your own static helper method like this:
static class DateTimeHelper
{
public static DateTime Tomorrow
{
get { return DateTime.Now.AddDays(1); }
}
}
Which you would use like this:
DateTime tomorrow = DateTimeHelper.Tomorrow;

You can place your tables in a div and add style to your table "float: left"
<div>
<table style="float: left">

</div>
or simply use css:

Unlike in PyQt5, in PySide2 the QThread.started signal is received/handled on the original thread, not the worker thread! Luckily it still receives all other signals on the worker thread.
In order to match PyQt5's behavior, you have to create the started signal yourself.
Here is an easy solution:
# Use this class instead of QThread
class QThread2(QThread):
# Use this signal instead of "started"
started2 = Signal()
def __init__(self):
QThread.__init__(self)
self.started.connect(self.onStarted)
def onStarted(self):
self.started2.emit()
One solution would be to use the plt.legend
function, even if you don't want an actual legend. You can specify the placement of the legend box by using the loc
keyterm. More information can be found at this website but I've also included an example showing how to place a legend:
ax.scatter(xa,ya, marker='o', s=20, c="lightgreen", alpha=0.9)
ax.scatter(xb,yb, marker='o', s=20, c="dodgerblue", alpha=0.9)
ax.scatter(xc,yc marker='o', s=20, c="firebrick", alpha=1.0)
ax.scatter(xd,xd,xd, marker='o', s=20, c="goldenrod", alpha=0.9)
line1 = Line2D(range(10), range(10), marker='o', color="goldenrod")
line2 = Line2D(range(10), range(10), marker='o',color="firebrick")
line3 = Line2D(range(10), range(10), marker='o',color="lightgreen")
line4 = Line2D(range(10), range(10), marker='o',color="dodgerblue")
plt.legend((line1,line2,line3, line4),('line1','line2', 'line3', 'line4'),numpoints=1, loc=2)
Note that because loc=2
, the legend is in the upper-left corner of the plot. And if the text overlaps with the plot, you can make it smaller by using legend.fontsize
, which will then make the legend smaller.
If you already have a directory in /usr/local
for the package you're installing, you can try deleting this directory.
In my case I had previously installed the package I was trying to install without using brew, and had then uninstalled it. There was a directory /usr/local/<my_package>/
left over from that previous install. I deleted this folder (sudo rm -rf /usr/local/<my_package>/
) and after that the brew link step was successful.

Would be correct if your function was correct. Unfortunately you are returning a pointer to a local variable in the function which means that it is a pointer to undefined data as soon as the function returns. You need to use heap allocation like malloc for the string in your function in order for the pointer you return to have any meaning. Then you need to remember to free it later.
run this in Command Prompt windows (cmd.exe).
set PATH=C:\xampp\php;%PATH%
change it depending where you put the php 7 installation.
I have a [submit] and a [preview] button, I want the preview to show the print view of the submitted form data, without persisting it to database. Therefore I want [preview] to open in a new tab, and submit to submit the data in the same window/tab.

Unless I am greatly mistaken, the answer is, "No, there is no way."
The basic problem in situations like that is the fact that you are calling a MySQL function and you're not actually setting a value. CI escapes values so that you can do a clean insert but it does not test to see if those values happen to be calling functions like aes_encrypt
, md5
, or (in this case) now()
. While in most situations this is wonderful, for those situations raw sql is the only recourse.
On a side, date('Y-m-d');
should work as a PHP version of NOW()
for MySQL. (It won't work for all versions of SQL though).
I think preprocessing is the way to go. You could use Notepad++ which has a regular expression replace option.
For example, if your file were like this:
"1,234","123","1,234"
"234","123","1,234"
123,456,789
Then, you could use the regular expression "([0-9]+),([0-9]+)"
and replace it with \1\2
1234,"123",1234
"234","123",1234
123,456,789
Then you could use x <- read.csv(file="x.csv",header=FALSE)
to read the file.
A really simple way to do this...
// create the option
var opt = $("<option>").val("myvalue").text("my text");
//append option to the select element
$(#my-select).append(opt);
This could be done in lots of ways, even in a single line if really you want to.
Quite simple actually:
mysql_query("
SELECT *
FROM `table`
WHERE `column` LIKE '%{$needle}%'
");
The %
is a wildcard for any characters set (none, one or many). Do note that this can get slow on very large datasets so if your database grows you'll need to use fulltext indices.
Technically, no. But what you can do is use a font size that is as tall as you would like the stretched font to be, and then condense it horizontally with font-stretch
.
You can use the -Q --help=target
options:
gcc -march=native -Q --help=target ...
The -v
option may also be of use.
You can see the documentation on the --help
option here.
You can use boolean indexing
:
df = pd.DataFrame({'Sales':[10,20,30,40,50], 'A':[3,4,7,6,1]})
print (df)
A Sales
0 3 10
1 4 20
2 7 30
3 6 40
4 1 50
s = 30
df1 = df[df['Sales'] >= s]
print (df1)
A Sales
2 7 30
3 6 40
4 1 50
df2 = df[df['Sales'] < s]
print (df2)
A Sales
0 3 10
1 4 20
It's also possible to invert mask
by ~
:
mask = df['Sales'] >= s
df1 = df[mask]
df2 = df[~mask]
print (df1)
A Sales
2 7 30
3 6 40
4 1 50
print (df2)
A Sales
0 3 10
1 4 20
print (mask)
0 False
1 False
2 True
3 True
4 True
Name: Sales, dtype: bool
print (~mask)
0 True
1 True
2 False
3 False
4 False
Name: Sales, dtype: bool
You can set timeout like this,
con.setConnectTimeout(connectTimeout);
con.setReadTimeout(socketTimeout);
You'll have to use the ChannelFactory class.
Here's an example:
var myBinding = new BasicHttpBinding();
var myEndpoint = new EndpointAddress("http://localhost/myservice");
using (var myChannelFactory = new ChannelFactory<IMyService>(myBinding, myEndpoint))
{
IMyService client = null;
try
{
client = myChannelFactory.CreateChannel();
client.MyServiceOperation();
((ICommunicationObject)client).Close();
myChannelFactory.Close();
}
catch
{
(client as ICommunicationObject)?.Abort();
}
}

Let me share my experience too,
I was trying to clone some project from the Gerrit repo where I got my public keys in account settings.
On the first attempt to make git clone
I got the following error:
Unable to negotiate with XX.XX.XX.XX port XXX: no matching key exchange
method found. Their offer: diffie-hellman-group1-sha1
I figured out that I need to pass the SSH option -oKexAlgorithms=+diffie-hellman-group1-sha1
somehow to git clone
.
Hopefully GIT_SSH_COMMAND
environment variable did the job:
export GIT_SSH_COMMAND="ssh -oKexAlgorithms=+diffie-hellman-group1-sha1"
But git clone
still didn't start to work.. Now it throws the (on topic):
Permission denied (publickey).
I got already SSH keys and didn't want to regenerate them. I checked plain SSH connection to the host and it was ok:
**** Welcome to Gerrit Code Review ****
Hi XXXXX, you have successfully connected over SSH.
Unfortunately, interactive shells are disabled.
To clone a hosted Git repository, use:
git clone ssh://[email protected]:xxx/REPOSITORY_NAME.git
I was confused a bit. I started again and turned on the debug for SSH via -vvv
option. And I saw the following:
debug1: read_passphrase: can't open /dev/tty: No such device or address
Possibly, it was an overhead for the GIT_SSH_COMMAND
env variable - my key was secured with passphrase (and I entered it when I was checking the login to the git repo host).
So, I decided to get rid of the phasphrase then. A simple command helped me:
ssh-keygen -p
Then I entered my passphrase for the "old passphrase" and just hit ENTER twice on the "new passphare" to leave it empty i.e. with no passphrase at all and to confirm my choice.
After that I got the freshly cloned repo on my local disk.
A general solution for any case/approach, mainly by using a form without a class or when we need access to any services to set the default value:
// src/Form/Extension/DefaultFormTypeExtension.php
class DefaultFormTypeExtension extends AbstractTypeExtension
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
if (null !== $options['default']) {
$builder->addEventListener(
FormEvents::PRE_SET_DATA,
function (FormEvent $event) use ($options) {
if (null === $event->getData()) {
$event->setData($options['default']);
}
}
);
}
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefault('default', null);
}
public function getExtendedType()
{
return FormType::class;
}
}
and register the form extension:
app.form_type_extension:
class: App\Form\Extension\DefaultFormTypeExtension
tags:
- { name: form.type_extension, extended_type: Symfony\Component\Form\Extension\Core\Type\FormType }
After that, we can use default
option in any form field:
$formBuilder->add('user', null, array('default' => $this->getUser()));
$formBuilder->add('foo', null, array('default' => 'bar'));
Since TypeScript 3.7 was released you can use optional chaining now.
Property example:
let x = foo?.bar.baz();
This is equvalent to:
let x = (foo === null || foo === undefined) ?
undefined :
foo.bar.baz();
Moreover you can call:
Optional Call
function(otherFn: (par: string) => void) {
otherFn?.("some value");
}
otherFn will be called only if otherFn won't be equal to null or undefined
Usage optional chaining in IF statement
This:
if (someObj && someObj.someProperty) {
// ...
}
can be replaced now with this
if (someObj?.someProperty) {
// ...
}

You want style image and Nav with float to each other then use like this
ol.widgets ul
{
list-style-image:url('some-img.gif');
}
ol.widgets ul li
{
float:left;
}
There are just two minor things here.
The first is in the following carousel indicator list items:
<li data-target="carousel" data-slide-to="0"></li>
You need to pass the data-target
attribute a selector which means the ID must be prefixed with #
. So change them to the following:
<li data-target="#carousel" data-slide-to="0"></li>
Secondly, you need to give the carousel a starting point so both the carousel indicator items and the carousel inner items must have one active
class. Like this:
<ol class="carousel-indicators">
<li data-target="#carousel" data-slide-to="0" class="active"></li>
<!-- Other Items -->
</ol>
<div class="carousel-inner">
<div class="item active">
<img src="https://picsum.photos/1500/600?image=1" alt="Slide 1" />
</div>
<!-- Other Items -->
</div>
We can create static constructor
static class StaticParent
{
StaticParent()
{
//write your initialization code here
}
}
and it is always parameter less.
static class StaticParent
{
static int i =5;
static StaticParent(int i) //Gives error
{
//write your initialization code here
}
}
and it doesn't have the access modifier
The issue here is that JSON, as a format, is generally parsed in full and then handled in-memory, which for such a large amount of data is clearly problematic.
The solution to this is to work with the data as a stream - reading part of the file, working with it, and then repeating.
The best option appears to be using something like ijson - a module that will work with JSON as a stream, rather than as a block file.
Edit: Also worth a look - kashif's comment about json-streamer
and Henrik Heino's comment about bigjson
.
This worked for me. I haven't used any third-party libraries. Just the ones that are shipped with Java.

If you have installed anaconda, but if you are not able to execute conda command from terminal, it means the path is not probably set, try :
export PATH=~/anaconda/bin:$PATH

According to Extensible Messaging and Presence Protocol (Wikipedia), the standard TCP port for the server is 5222.
The client would presumably use the same ports as the messaging protocol, but can also use http (port 80) and https (port 443) for message delivery. These have the advantage of working for users behind firewalls, so your network admin should not need to get involved.
html
<p id='longText'>Some very very very very very very very very very very very long string</p>
javascript (on doc ready)
var longText = $('#longText');
longText.text(longText.text().substr(0, 10));
If you have multiple words in the text, and want each to be limited to at most 10 chars, you could do:
var longText = $('#longText');
var text = longText.text();
var regex = /\w{11}\w*/, match;
while(match = regex.exec(text)) {
text = text.replace(match[0], match[0].substr(0, 10));
}
longText.text(text);
here is my solution in java using linkedlist.
class queue<T>{
static class Node<T>{
private T data;
private Node<T> next;
Node(T data){
this.data = data;
next = null;
}
}
Node firstTop;
Node secondTop;
void push(T data){
Node temp = new Node(data);
temp.next = firstTop;
firstTop = temp;
}
void pop(){
if(firstTop == null){
return;
}
Node temp = firstTop;
while(temp != null){
Node temp1 = new Node(temp.data);
temp1.next = secondTop;
secondTop = temp1;
temp = temp.next;
}
secondTop = secondTop.next;
firstTop = null;
while(secondTop != null){
Node temp3 = new Node(secondTop.data);
temp3.next = firstTop;
firstTop = temp3;
secondTop = secondTop.next;
}
}
}
Note : In this case, pop operation is very time consuming. So i won't suggest to create a queue using two stack.
Please double check that jenkins is not blocking this import. Go to script approvals and check to see if it is blocking it. If it is click allow.
Although internally it creates a new array and copies values into it, you can use Array.Resize<byte>()
for more readable code. Also you might want to consider checking the MemoryStream
class depending on what you're trying to achieve.
I use highcharts. They are very interactive (and very fancy I might add). You do have to get a little creative to access data from MySQL database, but if you have a general understanding of JavaScript and PHP, you should have no problems.
Here is a monkeyrunner script that sends touch and drags to an application. I have been using this to test that my application can handle rapid repetitive swipe gestures.
# This is a monkeyrunner jython script that opens a connection to an Android
# device and continually sends a stream of swipe and touch gestures.
#
# See http://developer.android.com/guide/developing/tools/monkeyrunner_concepts.html
#
# usage: monkeyrunner swipe_monkey.py
#
# Imports the monkeyrunner modules used by this program
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice
# Connects to the current device
device = MonkeyRunner.waitForConnection()
# A swipe left from (x1, y) to (x2, y) in 2 steps
y = 400
x1 = 100
x2 = 300
start = (x1, y)
end = (x2, y)
duration = 0.2
steps = 2
pause = 0.2
for i in range(1, 250):
# Every so often inject a touch to spice things up!
if i % 9 == 0:
device.touch(x2, y, 'DOWN_AND_UP')
MonkeyRunner.sleep(pause)
# Swipe right
device.drag(start, end, duration, steps)
MonkeyRunner.sleep(pause)
# Swipe left
device.drag(end, start, duration, steps)
MonkeyRunner.sleep(pause)
To answer this question from my understanding...
An authentication system that uses REST so that you do not need to actually track or manage the users in your system. This is done by using the HTTP methods POST, GET, PUT, DELETE. We take these 4 methods and think of them in terms of database interaction as CREATE, READ, UPDATE, DELETE (but on the web we use POST and GET because that is what anchor tags support currently). So treating POST and GET as our CREATE/READ/UPDATE/DELETE (CRUD) then we can design routes in our web application that will be able to deduce what action of CRUD we are achieving.
For example, in a Ruby on Rails application we can build our web app such that if a user who is logged in visits http://store.com/account/logout then the GET of that page can viewed as the user attempting to logout. In our rails controller we would build an action in that logs the user out and sends them back to the home page.
A GET on the login page would yield a form. a POST on the login page would be viewed as a login attempt and take the POST data and use it to login.
To me, it is a practice of using HTTP methods mapped to their database meaning and then building an authentication system with that in mind you do not need to pass around any session id's or track sessions.
I'm still learning -- if you find anything I have said to be wrong please correct me, and if you learn more post it back here. Thanks.
For the record only, to add to Spudley's answer, there is also the possibility to use position: absolute
and margins if you know the column widths.
For me, the main issue when chossing a method is whether you need the columns to fill the whole height (equal heights), where table-cell is the easiest method (if you don't care much for older browsers).
You can style (albeit with some constraints) the actual items themselves with the option
selector:
select, option { width: __; }
This way you are not only constraining the drop-down, but also all of its elements.
Use the CSS
property list-style-position
to position the bullet:
list-style-position:inside /* or outside */;
How about:
SimpleDateFormat fmt = new SimpleDateFormat("yyyyMMdd");
return fmt.format(date1).equals(fmt.format(date2));
You can also set the timezone to the SimpleDateFormat, if needed.

`List<String> unavailable = list1.stream()
.filter(e -> (list2.stream()
.filter(d -> d.getStr().equals(e))
.count())<1)
.collect(Collectors.toList());`
for this if i change to
`List<String> unavailable = list1.stream()
.filter(e -> (list2.stream()
.filter(d -> d.getStr().equals(e))
.count())>0)
.collect(Collectors.toList());`
will it give me list1 matched with list2 right?
Cmdlets in powershell accept a bunch of arguments. When these arguments are defined you can define a position for each of them.
This allows you to call a cmdlet without specifying the parameter name. So for the following cmdlet the path attribute is define with a position of 0 allowing you to skip typing -Path when invoking it and as such both the following will work.
Get-Item -Path C:\temp\thing.txt
Get-Item C:\temp\thing.txt
However if you specify more arguments than there are positional parameters defined then you will get the error.
Get-Item C:\temp\thing.txt "*"
As this cmdlet does not know how to accept the second positional parameter you get the error. You can fix this by telling it what the parameter is meant to be.
Get-Item C:\temp\thing.txt -Filter "*"
I assume you are getting the error on the following line of code as it seems to be the only place you are not specifying the parameter names correctly, and maybe it is treating the = as a parameter and $username as another parameter.
Set-ADUser $user -userPrincipalName = $newname
Try specifying the parameter name for $user and removing the =
Don't use spaces...

C99 offers some really cool stuff using anonymous arrays:
Removing pointless variables
{
int yes=1;
setsockopt(yourSocket, SOL_SOCKET, SO_REUSEADDR, &yes, sizeof(int));
}
becomes
setsockopt(yourSocket, SOL_SOCKET, SO_REUSEADDR, (int[]){1}, sizeof(int));
Passing a Variable Amount of Arguments
void func(type* values) {
while(*values) {
x = *values++;
/* do whatever with x */
}
}
func((type[]){val1,val2,val3,val4,0});
Static linked lists
int main() {
struct llist { int a; struct llist* next;};
#define cons(x,y) (struct llist[]){{x,y}}
struct llist *list=cons(1, cons(2, cons(3, cons(4, NULL))));
struct llist *p = list;
while(p != 0) {
printf("%d\n", p->a);
p = p->next;
}
}
Any I'm sure many other cool techniques I haven't thought of.
Officially google provide an Android API for this.
The API is currently being tested with a handful of partners, and will become available to all developers soon.
