Yes, you can do this.
The VM registration process should finish with the cloned VM usable in the new vCenter!
Good luck!
This is working for me
$('.Count').each(function () {
$(this).prop('Counter',0).animate({
Counter: $(this).text()
}, {
duration: 4000,
easing: 'swing',
step: function (now) {
$(this).text(Math.ceil(now));
}
});
});
Try this, works!
Excel.Worksheet sheet = xlWorkSheet;
Excel.Series series1 = seriesCollection.NewSeries();

Since ECMAScript6, one can use Set
:
var myArray = ['A', 'B', 'C'];
var mySet = new Set(myArray);
var hasB = mySet.has('B'); // true
var hasZ = mySet.has('Z'); // false
You can't do that, because GetFiles
only accepts a single search pattern. Instead, you can call GetFiles
with no pattern, and filter the results in code:
string[] extensions = new[] { ".jpg", ".tiff", ".bmp" };
FileInfo[] files =
dinfo.GetFiles()
.Where(f => extensions.Contains(f.Extension.ToLower()))
.ToArray();
If you're working with .NET 4, you can use the EnumerateFiles
method to avoid loading all FileInfo objects in memory at once:
string[] extensions = new[] { ".jpg", ".tiff", ".bmp" };
FileInfo[] files =
dinfo.EnumerateFiles()
.Where(f => extensions.Contains(f.Extension.ToLower()))
.ToArray();
All you needed was a plus :)

});
There is a great implementation of NavigationDrawer
that follows the Google Material Design Guidelines (and compatible down to API 10) - The MaterialDrawer library (link to GitHub). As of time of writing, May 2017, it's actively supported.
It's available in Maven Central repo. Gradle dependency setup:
compile 'com.mikepenz:materialdrawer:5.9.1'
Maven dependency setup:
<dependency>
<groupId>com.mikepenz</groupId>
<artifactId>materialdrawer</artifactId>
<version>5.9.1</version>

The return type of a lambda (in C++11) can be deduced, but only when there is exactly one statement, and that statement is a return
statement that returns an expression (an initializer list is not an expression, for example). If you have a multi-statement lambda, then the return type is assumed to be void.
Therefore, you should do this:
remove_if(rawLines.begin(), rawLines.end(), [&expression, &start, &end, &what, &flags](const string& line) -> bool
{
start = line.begin();
end = line.end();
bool temp = boost::regex_search(start, end, what, expression, flags);
return temp;
})
But really, your second expression is a lot more readable.
It looks like you can add it to your ~/.my.cnf, but it needs to be added as an argument to the init-command flag in your [client] section, like so:
[client]
init-command='set autocommit=0'
also, these two libraries can help you.

Creating an array or tuple of keys from an interface with safety compile-time checks requires a bit of creativity. Types are erased at run-time and object types (unordered, named) cannot be converted to tuple types (ordered, unnamed) without resorting to non-supported techniques.
The here proposed variants all consider/trigger a compile error in case of duplicate or missing tuple items given a reference object type like IMyTable
. For example declaring an array type of (keyof IMyTable)[]
cannot catch these errors.
In addition, they don't require a specific library (last variant uses ts-morph
, which I would consider a generic compiler wrapper), emit a tuple type as opposed to an object (only first solution creates an array) or wide array type (compare to these answers) and lastly don't need classes.
// Record type ensures, we have no double or missing keys, values can be neglected
function createKeys(keyRecord: Record<keyof IMyTable, any>): (keyof IMyTable)[] {
return Object.keys(keyRecord) as any
}
const keys = createKeys({ isDeleted: 1, createdAt: 1, title: 1, id: 1 })
// const keys: ("id" | "title" | "createdAt" | "isDeleted")[]

manual with auto-completion -
array, no tuple
If you don't like creating a record, take a look at this alternative with Set
and assertion types.
function createKeys<T extends readonly (keyof IMyTable)[] | [keyof IMyTable]>(
t: T & CheckMissing<T, IMyTable> & CheckDuplicate<T>): T {
return t
}
+

manual with auto-completion +-
more advanced, complex types
createKeys
does compile-time checks by merging the function parameter type with additional assertion types, that emit an error for not suitable input. (keyof IMyTable)[] | [keyof IMyTable]
is a "black magic" way to force inference of a tuple instead of an array from the callee side. Alternatively, you can use const assertions / as const
from caller side.
CheckMissing
checks, if T
misses keys from U
:
type CheckMissing<T extends readonly any[], U extends Record<string, any>> = {
[K in keyof U]: K extends T[number] ? never : K
}[keyof U] extends never ? T : T & "Error: missing keys"
type T1 = CheckMissing<["p1"], {p1:any, p2:any}> //["p1"] & "Error: missing keys"
type T2 = CheckMissing<["p1", "p2"], { p1: any, p2: any }> // ["p1", "p2"]
Note: T & "Error: missing keys"
is just for nice IDE errors. You could also write never
. CheckDuplicates
checks double tuple items:
type CheckDuplicate<T extends readonly any[]> = {
[P1 in keyof T]: "_flag_" extends
{ [P2 in keyof T]: P2 extends P1 ? never :
T[P2] extends T[P1] ? "_flag_" : never }[keyof T] ?
[T[P1], "Error: duplicate"] : T[P1]
}
type T3 = CheckDuplicate<[1, 2, 3]> // [1, 2, 3]
type T4 = CheckDuplicate<[1, 2, 1]>
// [[1, "Error: duplicate"], 2, [1, "Error: duplicate"]]
Note: More infos on unique item checks in tuples are in this post. With TS 4.1, we also can name missing keys in the error string - take a look at this Playground.
With version 4.1, TypeScript officially supports conditional recursive types, which can be potentially used here as well. Though, the type computation is expensive due to combinatory complexity - performance degrades massively for more than 5-6 items. I list this alternative for completeness (Playground):
type Prepend<T, U extends any[]> = [T, ...U] // TS 4.0 variadic tuples
type Keys<T extends Record<string, any>> = Keys_<T, []>
type Keys_<T extends Record<string, any>, U extends PropertyKey[]> =
{
[P in keyof T]: {} extends Omit<T, P> ? [P] : Prepend<P, Keys_<Omit<T, P>, U>>
}[keyof T]
const t1: Keys<IMyTable> = ["createdAt", "isDeleted", "id", "title"] // ?

ts-morph is chosen here, as it is a tad simpler wrapper alternative to the original TS compiler API. Of course, you can also use the compiler API directly. Let's look at the generator code:
// ./src/mybuildstep.ts
import {Project, VariableDeclarationKind, InterfaceDeclaration } from "ts-morph";
const project = new Project();
// source file with IMyTable interface
const sourceFile = project.addSourceFileAtPath("./src/IMyTable.ts");
// target file to write the keys string array to
const destFile = project.createSourceFile("./src/generated/IMyTable-keys.ts", "", {
overwrite: true // overwrite if exists
});
function createKeys(node: InterfaceDeclaration) {
const allKeys = node.getProperties().map(p => p.getName());
destFile.addVariableStatement({
declarationKind: VariableDeclarationKind.Const,
declarations: [{
name: "keys",
initializer: writer =>
writer.write(`${JSON.stringify(allKeys)} as const`)
}]
});
}
createKeys(sourceFile.getInterface("IMyTable")!);
destFile.saveSync(); // flush all changes and write to disk
After we compile and run this file with tsc && node dist/mybuildstep.js
, a file ./src/generated/IMyTable-keys.ts
with following content is generated:
// ./src/generated/IMyTable-keys.ts
const keys = ["id","title","createdAt","isDeleted"] as const;

As stated by pnt you can have multiple versions of both 32bit and 64bit Java installed at the same time on the same machine.
Taking it further from there: Here's how it might be possible to set any runtime parameters for each of those installations:
You can run javacpl.exe or javacpl.cpl of the respective Java-version itself (bin-folder). The specific control panel opens fine. Adding parameters there is possible.

If anyone is coming here looking to do this with Font Awesome Icons (like I was) view here: https://fontawesome.com/how-to-use/on-the-web/styling/icons-in-a-list
<ul class="fa-ul">

<li><i class="fa-li fa fa-spinner fa-spin"></i>as bullets</li>
<li><i class="fa-li fa fa-square"></i>in lists</li>

The fa-ul
and fa-li
classes easily replace default bullets in unordered lists.
I want to clarify some things here for the original poster which others have alluded to but haven't really explicitly stated. When you say that you want a Unique List, that is the very definition of an Ordered Set. Some other key differences between the Set Interface and the List interface are that List allows you to specify the insert index. So, the question is do you really need the List Interface (i.e. for compatibility with a 3rd party library, etc.), or can you redesign your software to use the Set interface? You also have to consider what you are doing with the interface. Is it important to find elements by their index? How many elements do you expect in your set? If you are going to have many elements, is ordering important?
If you really need a List which just has a unique constraint, there is the Apache Common Utils class org.apache.commons.collections.list.SetUniqueList which will provide you with the List interface and the unique constraint. Mind you, this breaks the List interface though. You will, however, get better performance from this if you need to seek into the list by index. If you can deal with the Set interface, and you have a smaller data set, then LinkedHashSet might be a good way to go. It just depends on the design and intent of your software.
Again, there are certain advantages and disadvantages to each collection. Some fast inserts but slow reads, some have fast reads but slow inserts, etc. It makes sense to spend a fair amount of time with the collections documentation to fully learn about the finer details of each class and interface.

CMD Cheat Sheet
Cmd.exe
Getting Help
Punctuation
Naming Files
Starting Programs
Keys
CMD.exe
First thing to remember its a way of operating a computer. It's the way we did it before WIMP (Windows, Icons, Mouse, Popup menus) became common. It owes it roots to CPM, VMS, and Unix. It was used to start programs and copy and delete files. Also you could change the time and date.
For help on starting CMD type cmd /?
. You must start it with either the /k
or /c
switch unless you just want to type in it.
Getting Help
For general help. Type Help
in the command prompt. For each command listed type help <command>
(eg help dir
) or <command> /?
(eg dir /?
).
Some commands have sub commands. For example schtasks /create /?
.
The NET
command's help is unusual. Typing net use /?
is brief help. Type net help use
for full help. The same applies at the root - net /?
is also brief help, use net help
.
References in Help to new behaviour are describing changes from CMD in OS/2 and Windows NT4 to the current CMD which is in Windows 2000 and later.
WMIC
is a multipurpose command. Type wmic /?
.
Punctuation
& seperates commands on a line.
&& executes this command only if previous command's errorlevel is 0.
|| (not used above) executes this command only if previous command's
errorlevel is NOT 0
> output to a file
>> append output to a file
< input from a file
2> Redirects command error output to the file specified. (0 is StdInput, 1 is StdOutput, and 2 is StdError)
2>&1 Redirects command error output to the same location as command output.
| output of one command into the input of another command
^ escapes any of the above, including itself, if needed to be passed
to a program
" parameters with spaces must be enclosed in quotes
+ used with copy to concatenate files. E.G. copy file1+file2 newfile
, used with copy to indicate missing parameters. This updates the files
modified date. E.G. copy /b file1,,
%variablename% a inbuilt or user set environmental variable
!variablename! a user set environmental variable expanded at execution
time, turned with SelLocal EnableDelayedExpansion command
%<number> (%1) the nth command line parameter passed to a batch file. %0
is the batchfile's name.
%* (%*) the entire command line.
%CMDCMDLINE% - expands to the original command line that invoked the
Command Processor (from set /?).
%<a letter> or %%<a letter> (%A or %%A) the variable in a for loop.
Single % sign at command prompt and double % sign in a batch file.
\\ (\\servername\sharename\folder\file.ext) access files and folders via UNC naming.
: (win.ini:streamname) accesses an alternative steam. Also separates drive from rest of path.
. (win.ini) the LAST dot in a file path separates the name from extension
. (dir .\*.txt) the current directory
.. (cd ..) the parent directory
\\?\ (\\?\c:\windows\win.ini) When a file path is prefixed with \\?\ filename checks are turned off.
Naming Files
< > : " / \ | Reserved characters. May not be used in filenames.
Reserved names. These refer to devices eg,
copy filename con
which copies a file to the console window.
CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4,
COM5, COM6, COM7, COM8, COM9, LPT1, LPT2,
LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9
CONIN$, CONOUT$, CONERR$
--------------------------------
Maximum path length 260 characters
Maximum path length (\\?\) 32,767 characters (approx - some rare characters use 2 characters of storage)
Maximum filename length 255 characters
Starting a Program
See start /?
and call /?
for help on all three ways.
There are two types of Windows programs - console or non console (these are called GUI even if they don't have one). Console programs attach to the current console or Windows creates a new console. GUI programs have to explicitly create their own windows.
If a full path isn't given then Windows looks in
The directory from which the application loaded.
The current directory for the parent process.
Windows NT/2000/XP: The 32-bit Windows system directory. Use the GetSystemDirectory function to get the path of this directory. The name of this directory is System32.
Windows NT/2000/XP: The 16-bit Windows system directory. There is no function that obtains the path of this directory, but it is searched. The name of this directory is System.
The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
The directories that are listed in the PATH environment variable.
Specify a program name
This is the standard way to start a program.
c:\windows\notepad.exe
In a batch file the batch will wait for the program to exit. When typed the command prompt does not wait for graphical programs to exit.
If the program is a batch file control is transferred and the rest of the calling batch file is not executed.
Use Start command
Start
starts programs in non standard ways.
start "" c:\windows\notepad.exe
Start
starts a program and does not wait. Console programs start in a new window. Using the /b
switch forces console programs into the same window, which negates the main purpose of Start.
Start uses the Windows graphical shell - same as typing in WinKey + R (Run dialog). Try
start shell:cache
Also program names registered under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
can also be typed without specifying a full path.
Also note the first set of quotes, if any, MUST be the window title.
Use Call command
Call is used to start batch files and wait for them to exit and continue the current batch file.
Other Filenames
Typing a non program filename is the same as double clicking the file.
Keys
Ctrl + C exits a program without exiting the console window.
For other editing keys type Doskey /?
.
? and ? recall commands
ESC clears command line
F7 displays command history
ALT+F7 clears command history
F8 searches command history
F9 selects a command by number
ALT+F10 clears macro definitions
Also not listed
Ctrl + ?or? Moves a word at a time
Ctrl + Backspace Deletes the previous word
Home Beginning of line
End End of line
Ctrl + End Deletes to end of line
onclick vs addEventListener. A matter of preference perhaps (where IE>9).
// Using closures
function onClickLink(e, index) {
alert(index);
return false;
}
var div = document.getElementById('div');
for (var i = 0; i < 10; i++) {
var link = document.createElement('a');
link.setAttribute('href', '#');
link.innerHTML = i + '';
link.addEventListener('click', (function(e) {
var index = i;
return function(e) {
return onClickLink(e, index);
}
})(), false);
div.appendChild(link);
div.appendChild(document.createElement('BR'));
}
How abut just using a plain data-* attribute, not as cool as a closure, but..
function onClickLink(e) {
alert(e.target.getAttribute('data-index'));
return false;
}
var div = document.getElementById('div');
for (var i = 0; i < 10; i++) {
var link = document.createElement('a');
link.setAttribute('href', '#');
link.setAttribute('data-index', i);
link.innerHTML = i + ' Hello';
link.addEventListener('click', onClickLink, false);
div.appendChild(link);
div.appendChild(document.createElement('BR'));
}
If you want to count the number of records in your table, simply run:
SELECT COUNT(*) FROM your_table;
Just do System.out.println(e.getActionCommand());
inside actionPerformed(ActionEvent e)
function. This will tell you which command is just performed.
or
if(e.getActionCommand().equals("Add")){
System.out.println("Add button pressed");
}
The error you quote has nothing to do with pg_hba.conf
; it's failing to connect, not failing to authorize the connection.
Do what the error message says:
Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections
You haven't shown the command that produces the error. Assuming you're connecting on localhost
port 5432
(the defaults for a standard PostgreSQL install), then either:
PostgreSQL isn't running
PostgreSQL isn't listening for TCP/IP connections (listen_addresses
in postgresql.conf
)
PostgreSQL is only listening on IPv4 (0.0.0.0
or 127.0.0.1
) and you're connecting on IPv6 (::1
) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.
PostgreSQL is listening on a different port to the one you're connecting on
(unlikely) there's an iptables
rule blocking loopback connections
(If you are not connecting on localhost
, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).
So ... check those:
ps -f -u postgres
should list postgres
processes
sudo lsof -n -u postgres |grep LISTEN
or sudo netstat -ltnp | grep postgres
should show the TCP/IP addresses and ports PostgreSQL is listening on
BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:
$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 12345?
px = dp * (dpi / 160)
dp = px * (160 / dpi)
There is no newline, just the div
is a block element.
You can make the div
inline by adding display: inline
, which may be what you want.
There is comma missing in your tuple.
insert the comma between the tuples as shown:
pack_size = (('1', '1'),('3', '3'),(b, b),(h, h),(d, d), (e, e),(r, r))
Do the same for all
DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];
for (int i = 0; i < dr_art_line_2.Rows.Count; i++)
{
QuantityInIssueUnit_value = Convert.ToInt32(dr_art_line_2.Rows[i]["columnname"]);
//Similarly for QuantityInIssueUnit_uom.
}
I looked at the HTML generated by the UI Dialog. It renders buttons pane like this:
<div class="ui-dialog-buttonpane ui-widget-content ui-helper-clearfix">
<button type="button" class="ui-state-default ui-corner-all">Delete all items in recycle bin</button>
<button type="button" class="ui-state-default ui-corner-all different" style="border: 1px solid blue;">Cancel</button>
</div>
Adding a class to Cancel button should be easy.
$('.ui-dialog-buttonpane :last-child').css('background-color', '#ccc');
This will make the Cancel button little grey. You can style this button however you like.
Above code assumes that the Cancel button is the last button. The fool proof way to do it would be
$('.ui-dialog-buttonpane :button')
.each(
function()
{
if($(this).text() == 'Cancel')
{
//Do your styling with 'this' object.
}
}
);
Continuous Integration
Continuous Delivery
Continuous Deployment
CI/CD is a journey. Not a destination.
These stages are suggestions. You can adapt the stages based on your business need. Some stages can be repeated for multiple types of testing, security, and performance. Depending on the complexity of your project and the structure of your teams, some stages can be repeated several times at different levels. For example, the end product of one team can become a dependency in the project of the next team. This means that the first team’s end product is subsequently staged as an artifact in the next team’s project.

Practicing Continuous Integration and Continuous Delivery on AWS
You can define a mutable above the scope of the threaded function, and add the result to that. (I also modified the code to be python3 compatible)
returns = {}
def foo(bar):
print('hello {0}'.format(bar))
returns[bar] = 'foo'
from threading import Thread
t = Thread(target=foo, args=('world!',))
t.start()
t.join()
print(returns)
This returns {'world!': 'foo'}
If you use the function input as the key to your results dict, every unique input is guaranteed to give an entry in the results
In case you are using the Map with out generic, then you need to convert the value into String and then try to convert to Long. Below is sample code
Map map = new HashMap();
map.put("name", "John");
map.put("time", "9648512236521");
map.put("age", "25");
long time = Long.valueOf((String)map.get("time")).longValue() ;
int age = Integer.valueOf((String) map.get("aget")).intValue();
System.out.println(time);
System.out.println(age);
I found one interesting site which seems pretty detailed on how you could setup a ubuntu for iPhone development. But it's a little old from November 2008 for the SDK 2.0.
Ubuntu 8.10 for iPhone open toolchain SDK2.0
The instructions also include something about the Android SDK/Emulator which you can leave out.
I realise this is an older question, but I recently came across this need and came up with the following solution using jQuery and CSS:
jQuery('select[name*="lstDestinations"] option').hover(
function() {
jQuery(this).addClass('highlight');
}, function() {
jQuery(this).removeClass('highlight');
}
);
and the css:
.highlight {
background-color:#333;
cursor:pointer;
}
Perhaps this helps someone else.
Hope this will help a little
you can resolve this problem in the following way
f = lambda x: x==2
if f(3):
print("do logic")
else:
print("another logic")
You can't. The CLR won't let you. A stack overflow is a fatal error and can't be recovered from.
Use
if (Build.VERSION.SDK_INT >= 19) {
mWebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
}
It should solve the error.
Simple use _.isEqual
method, it will work for all comparing...
- Note: This method supports comparing arrays, array buffers, booleans, * date objects, error objects, maps, numbers,
Object
objects, regexes, * sets, strings, symbols, and typed arrays.Object
objects are compared * by their own, not inherited, enumerable properties. Functions and DOM * nodes are not supported.
So if you have below:
const firstName = {name: "Alireza"};
const otherName = {name: "Alireza"};
If you do: _.isEqual(firstName, otherName);
,
it will return true
And if const fullName = {firstName: "Alireza", familyName: "Dezfoolian"};
If you do: _.isEqual(firstName, fullName);
,

The problem: You want to backup you image container WITH the data volumes in it but this option is Not out off the box, The straight forward and trivial way would be copy the volumes path and backup the docker image 'reload it and and link it both together. but this solution seems to be clumsy and not sustainable and maintainable - You would need to create a cron job that would make this flow each time.
Solution: Using dockup - Docker image to backup your Docker container volumes and upload it to s3 (Docker + Backup = dockup) . dockup will use your AWS credentials to create a new bucket with name as per the environment variable ,gets the configured volumes and will be tarballed, gzipped, time-stamped and uploaded to the S3 bucket.
Steps:
docker-compose.yml
and attach the env.txt
configuration file to it, The data should be uploaded to a dedicated secured s3 bucket and ready to be reloaded on DRP executions. in order to verify which volumes path to configure run docker inspect <service-name>
and locate the volumes :"Volumes": { "/etc/service-example": {}, "/service-example": {} },
Edit the content of the configuration file env.txt
, and place it on the project path:
AWS_ACCESS_KEY_ID=<key_here>
AWS_SECRET_ACCESS_KEY=<secret_here>
AWS_DEFAULT_REGION=us-east-1
BACKUP_NAME=service-backup
PATHS_TO_BACKUP=/etc/service-example /service-example
S3_BUCKET_NAME=docker-backups.example.com
RESTORE=false
Run the dockup container
$ docker run --rm \ --env-file env.txt \ --volumes-from <service-name> \ --name dockup tutum/dockup:latest
I have observed one case when eclipse when in forced quit, or Alt-f2 xkill
ed in linux, an attempt to immediately open eclipse shows that error. Even the metadat/.lock file is not present in that case.
However it starts working after a span of about two minutes
I have personally found some errors in when using unix_timestamp based date converstions from dd-MMM-yyyy format to yyyy-mm-dd, using spark 1.6, but this may extend into recent versions. Below I explain a way to solve the problem using java.time that should work in all versions of spark:
I've seen errors when doing:
from_unixtime(unix_timestamp(StockMarketClosingDate, 'dd-MMM-yyyy'), 'yyyy-MM-dd') as FormattedDate
Below is code to illustrate the error, and my solution to fix it. First I read in stock market data, in a common standard file format:
import sys.process._
import org.apache.spark.sql.SQLContext
import org.apache.spark.sql.functions.udf
import org.apache.spark.sql.types.{StructType, StructField, StringType, IntegerType, DateType}
import sqlContext.implicits._
val EODSchema = StructType(Array(
StructField("Symbol" , StringType, true), //$1
StructField("Date" , StringType, true), //$2
StructField("Open" , StringType, true), //$3
StructField("High" , StringType, true), //$4
StructField("Low" , StringType, true), //$5
StructField("Close" , StringType, true), //$6
StructField("Volume" , StringType, true) //$7
))
val textFileName = "/user/feeds/eoddata/INDEX/INDEX_19*.csv"
// below is code to read using later versions of spark
//val eoddata = spark.read.format("csv").option("sep", ",").schema(EODSchema).option("header", "true").load(textFileName)
// here is code to read using 1.6, via, "com.databricks:spark-csv_2.10:1.2.0"
val eoddata = sqlContext.read
.format("com.databricks.spark.csv")
.option("header", "true") // Use first line of all files as header
.option("delimiter", ",") //.option("dateFormat", "dd-MMM-yyyy") failed to work
.schema(EODSchema)
.load(textFileName)
eoddata.registerTempTable("eoddata")
And here is the date conversions having issues:
%sql
-- notice there are errors around the turn of the year
Select
e.Date as StringDate
, cast(from_unixtime(unix_timestamp(e.Date, "dd-MMM-yyyy"), 'YYYY-MM-dd') as Date) as ProperDate
, e.Close
from eoddata e
where e.Symbol = 'SPX.IDX'
order by cast(from_unixtime(unix_timestamp(e.Date, "dd-MMM-yyyy"), 'YYYY-MM-dd') as Date)
limit 1000
A chart made in zeppelin shows spikes, which are errors.
and here is the check that shows the date conversion errors:
// shows the unix_timestamp conversion approach can create errors
val result = sqlContext.sql("""
Select errors.* from
(
Select
t.*
, substring(t.OriginalStringDate, 8, 11) as String_Year_yyyy
, substring(t.ConvertedCloseDate, 0, 4) as Converted_Date_Year_yyyy
from
( Select
Symbol
, cast(from_unixtime(unix_timestamp(e.Date, "dd-MMM-yyyy"), 'YYYY-MM-dd') as Date) as ConvertedCloseDate
, e.Date as OriginalStringDate
, Close

where e.Symbol = 'SPX.IDX'
) t
) errors
where String_Year_yyyy <> Converted_Date_Year_yyyy
""")
//df.withColumn("tx_date", to_date(unix_timestamp($"date", "M/dd/yyyy").cast("timestamp")))
result.registerTempTable("SPX")
result.cache()
result.show(100)
result: org.apache.spark.sql.DataFrame = [Symbol: string, ConvertedCloseDate: date, OriginalStringDate: string, Close: string, String_Year_yyyy: string, Converted_Date_Year_yyyy: string]

FINISHED
After this result, I switched to java.time conversions with a UDF like this, which worked for me:
// now we will create a UDF that uses the very nice java.time library to properly convert the silly stockmarket dates
// start by importing the specific java.time libraries that superceded the joda.time ones
import java.time.LocalDate
import java.time.format.DateTimeFormatter
// now define a specific data conversion function we want
def fromEODDate (YourStringDate: String): String = {
val formatter = DateTimeFormatter.ofPattern("dd-MMM-yyyy")
var retDate = LocalDate.parse(YourStringDate, formatter)
// this should return a proper yyyy-MM-dd date from the silly dd-MMM-yyyy formats
// now we format this true local date with a formatter to the desired yyyy-MM-dd format
val retStringDate = retDate.format(DateTimeFormatter.ISO_LOCAL_DATE)
return(retStringDate)
}
Now I register it as a function for use in sql:
sqlContext.udf.register("fromEODDate", fromEODDate(_:String))
and check the results, and rerun test:
val results = sqlContext.sql("""
Select
e.Symbol as Symbol
, e.Date as OrigStringDate
, Cast(fromEODDate(e.Date) as Date) as ConvertedDate

from eoddata e
order by Cast(fromEODDate(e.Date) as Date)
""")
results.printSchema()
results.cache()
results.registerTempTable("results")
results.show(10)
results: org.apache.spark.sql.DataFrame = [Symbol: string, OrigStringDate: string, ConvertedDate: date, Open: string, High: string, Low: string, Close: string]

only showing top 10 rows
which looks ok, and I rerun my chart, to see if there are errors/spikes:
As you can see, no more spikes or errors. I now use a UDF as I've shown to apply my date format transformations to a standard yyyy-MM-dd format, and have not had spurious errors since. :-)
This question is already answered, but i also got same issue to debug Springboot + gradle + jHipster,
Mostly Spring boot application can debug by right click and debug, but when you use gradle, having some additional environment parameter setup then it is not possible to debug directly.
To resolve this, Eclipse provided one additional features as Remote Java Application
by using this features you can debug your application.
Follow below step:
run your gradle application with
./gradlew bootRun --debug-jvm
command
Now go to eclipse --> right click project and Debug configuration --> Remote Java Application.
add you host and port as localhost and port as 5005 (default for gradle debug, you can change it)
Refer for more detail and step.
The response from Marco is the BEST solution. I needed to control my error handling, and I mean really CONTROL it. Of course, I have extended the solution a little and created a full error management system that manages everything. I have also read about this solution in other blogs and it seems very acceptable by most of the advanced developers.
Here is the final code that I am using:
protected void Application_EndRequest()
{
if (Context.Response.StatusCode == 404)
{
var exception = Server.GetLastError();
var httpException = exception as HttpException;
Response.Clear();
Server.ClearError();
var routeData = new RouteData();
routeData.Values["controller"] = "ErrorManager";
routeData.Values["action"] = "Fire404Error";
routeData.Values["exception"] = exception;
Response.StatusCode = 500;
if (httpException != null)
{
Response.StatusCode = httpException.GetHttpCode();
switch (Response.StatusCode)
{
case 404:
routeData.Values["action"] = "Fire404Error";
break;
}
}
// Avoid IIS7 getting in the middle
Response.TrySkipIisCustomErrors = true;
IController errormanagerController = new ErrorManagerController();
HttpContextWrapper wrapper = new HttpContextWrapper(Context);
var rc = new RequestContext(wrapper, routeData);
errormanagerController.Execute(rc);
}
}
and inside my ErrorManagerController :
public void Fire404Error(HttpException exception)
{
//you can place any other error handling code here
throw new PageNotFoundException("page or resource");
}
Now, in my Action, I am throwing a Custom Exception that I have created. And my Controller is inheriting from a custom Controller Based class that I have created. The Custom Base Controller was created to override error handling. Here is my custom Base Controller class:
public class MyBasePageController : Controller
{
protected override void OnException(ExceptionContext filterContext)
{
filterContext.GetType();
filterContext.ExceptionHandled = true;
this.View("ErrorManager", filterContext).ExecuteResult(this.ControllerContext);
base.OnException(filterContext);
}
}
The "ErrorManager" in the above code is just a view that is using a Model based on ExceptionContext
My solution works perfectly and I am able to handle ANY error on my website and display different messages based on ANY exception type.
You can just make a list:
import random
list1=['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
b=random.randint(0,7)
print(list1[b])
Append new column in existing csv file using python without header name
default_text = 'Some Text'
# Open the input_file in read mode and output_file in write mode
with open('problem-one-answer.csv', 'r') as read_obj, \
open('output_1.csv', 'w', newline='') as write_obj:
# Create a csv.reader object from the input file object
csv_reader = reader(read_obj)
# Create a csv.writer object from the output file object
csv_writer = csv.writer(write_obj)
# Read each row of the input csv file as list
for row in csv_reader:
# Append the default text in the row / list
row.append(default_text)
# Add the updated row / list to the output file
csv_writer.writerow(row)
Thankyou
Actually, you can use two phases to translate your texts in Swift projects:
1) The first phase is using the old way to create all your translatable strings:
NSLocalisedString("Text to translate", comment: "Comment to comment")
1.1) Then you should use genstrings to generate Localizable.strings:
$ genstrings *swift
2) Afterwards, you should use this answer.
2.1) Use your XCode "Find and Replace" option based on the regular expression. As for the given example (if you have no comments) the regular expression will be:
NSLocalizedString\((.*)\, comment:\ \"\"\)
and replace it with
$1.localized
or (if you have comments)
NSLocalizedString\((.*)\, comment:\ (.*)\)
and replace it with
$1.localizedWithComment(comment: $2)
You are free to play with regex and different extension combinations as you wish. The general way is splitting the whole process in two phases. Hope that helps.
Since style A
is not allowed in C++ and you don't want style B
then how about using style BX
:
FooBar fb = { /*.foo=*/ 12, /*.bar=*/ 3.4 }; // :)
At least help at some extent.
I have just been faced with the same challenge, but I thought "Why programming this in Python if you can solve it with a simple "grep"?, which led to the following Python code:
import subprocess
from subprocess import PIPE
try:
output1, errors1 = subprocess.Popen(["c:\\cygwin\\bin\\grep", "-Fvf" ,"c:\\file1.txt", "c:\\file2.txt"], shell=True, stdout=PIPE, stderr=PIPE).communicate();
output2, errors2 = subprocess.Popen(["c:\\cygwin\\bin\\grep", "-Fvf" ,"c:\\file2.txt", "c:\\file1.txt"], shell=True, stdout=PIPE, stderr=PIPE).communicate();
if (len(output1) + len(output2) + len(errors1) + len(errors2) > 0):
print ("Compare result : There are differences:");
if (len(output1) + len(output2) > 0):
print (" Output differences : ");
print (output1);
print (output2);
if (len(errors1) + len(errors2) > 0):
print (" Errors : ");
print (errors1);
print (errors2);
else:
print ("Compare result : Both files are equal");
except Exception as ex:
print("Compare result : Exception during comparison");
print(ex);
raise;
The trick behind this is the following:
grep -Fvf file1.txt file2.txt
verifies if all entries in file2.txt are present in file1.txt. By doing this in both directions we can see if the content of both files are "equal". I put "equal" between quotes because duplicate lines are disregarded in this way of working.
Obviously, this is just an example: you can replace grep
by any commandline file comparison tool.
You want to multiply out to milliseconds as the fractional part is discarded.
SELECT DATEADD(ms, 121.25 * 1000, 0)
If you want it without the date portion you can use CONVERT, with style 114
SELECT CONVERT(varchar, DATEADD(ms, 121.25 * 1000, 0), 114)
You should compare dates in sql just like you compare number values,
SELECT * FROM Product_sales
WHERE From_date >= '2013-01-01' AND To_date <= '2013-01-20'
The fastest way to do file I/O from C# is to use the Windows ReadFile and WriteFile functions. I have written a C# class that encapsulates this capability as well as a benchmarking program that looks at differnet I/O methods, including BinaryReader and BinaryWriter. See my blog post at:
http://designingefficientsoftware.wordpress.com/2011/03/03/efficient-file-io-from-csharp/
Since the stack is already unwound when entering the catch block, the solution in my case was to not catch certain exceptions which then lead to a SIGABRT. In the signal handler for SIGABRT I then fork() and execl() either gdb (in debug builds) or Google breakpads stackwalk (in release builds). Also I try to only use signal handler safe functions.
GDB:
static const char BACKTRACE_START[] = "<2>--- backtrace of entire stack ---\n";
static const char BACKTRACE_STOP[] = "<2>--- backtrace finished ---\n";
static char *ltrim(char *s)
{
while (' ' == *s) {
s++;
}
return s;
}
void Backtracer::print()
{
int child_pid = ::fork();
if (child_pid == 0) {
// redirect stdout to stderr
::dup2(2, 1);
// create buffer for parent pid (2+16+1 spaces to allow up to a 64 bit hex parent pid)
char pid_buf[32];
const char* stem = " ";
const char* s = stem;
char* d = &pid_buf[0];
while (static_cast<bool>(*s))
{
*d++ = *s++;
}
*d-- = '\0';
char* hexppid = d;
// write parent pid to buffer and prefix with 0x
int ppid = getppid();
while (ppid != 0) {
*hexppid = ((ppid & 0xF) + '0');
if(*hexppid > '9') {
*hexppid += 'a' - '0' - 10;
}
--hexppid;
ppid >>= 4;
}
*hexppid-- = 'x';
*hexppid = '0';
// invoke GDB
char name_buf[512];
name_buf[::readlink("/proc/self/exe", &name_buf[0], 511)] = 0;
ssize_t r = ::write(STDERR_FILENO, &BACKTRACE_START[0], sizeof(BACKTRACE_START));
(void)r;
::execl("/usr/bin/gdb",
"/usr/bin/gdb", "--batch", "-n", "-ex", "thread apply all bt full", "-ex", "quit",
&name_buf[0], ltrim(&pid_buf[0]), nullptr);
::exit(1); // if GDB failed to start
} else if (child_pid == -1) {
::exit(1); // if forking failed
} else {
// make it work for non root users
if (0 != getuid()) {
::prctl(PR_SET_PTRACER, PR_SET_PTRACER_ANY, 0, 0, 0);
}
::waitpid(child_pid, nullptr, 0);
ssize_t r = ::write(STDERR_FILENO, &BACKTRACE_STOP[0], sizeof(BACKTRACE_STOP));
(void)r;
}
}
minidump_stackwalk:
static bool dumpCallback(const google_breakpad::MinidumpDescriptor& descriptor, void* context, bool succeeded)
{
int child_pid = ::fork();
if (child_pid == 0) {
::dup2(open("/dev/null", O_WRONLY), 2); // ignore verbose output on stderr
ssize_t r = ::write(STDOUT_FILENO, &MINIDUMP_STACKWALK_START[0], sizeof(MINIDUMP_STACKWALK_START));
(void)r;
::execl("/usr/bin/minidump_stackwalk", "/usr/bin/minidump_stackwalk", descriptor.path(), "/usr/share/breakpad-syms", nullptr);
::exit(1); // if minidump_stackwalk failed to start
} else if (child_pid == -1) {
::exit(1); // if forking failed
} else {
::waitpid(child_pid, nullptr, 0);
ssize_t r = ::write(STDOUT_FILENO, &MINIDUMP_STACKWALK_STOP[0], sizeof(MINIDUMP_STACKWALK_STOP));
(void)r;
}
::remove(descriptor.path()); // this is not signal safe anymore but should still work
return succeeded;
}
Edit: To make it work for breakpad I also had to add this:
std::set_terminate([]()
{
ssize_t r = ::write(STDERR_FILENO, EXCEPTION, sizeof(EXCEPTION));
(void)r;
google_breakpad::ExceptionHandler::WriteMinidump(std::string("/tmp"), dumpCallback, NULL);
exit(1); // avoid creating a second dump by not calling std::abort
});

It is not printing correctly because you need to use Base64 encoding. With Java 8 you can encode using Base64 encoder class.
public static String toSHA1(byte[] convertme) throws NoSuchAlgorithmException {
MessageDigest md = MessageDigest.getInstance("SHA-1");
return Base64.getEncoder().encodeToString(md.digest(convertme));
}

This will give you your expected output of 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8
For React Router v4+
Assuming that you won't be needing to navigate during the initial render itself (for which you can use <Redirect>
component), this is what we are doing in our app.
Define an empty route which returns null, this will allow you to get the access to the history object. You need to do this at the top level where your Router
is defined.
Now you can do all the things that can be done on history like history.push()
, history.replace()
, history.go(-1)
etc!
import React from 'react';
import { HashRouter, Route } from 'react-router-dom';
let routeHistory = null;
export function navigateTo(path) {
if(routeHistory !== null) {
routeHistory.push(path);
}
}
export default function App(props) {
return (
<HashRouter hashType="noslash">
<Route
render={({ history }) => {
routeHistory = history;
return null;
}}
/>
{/* Rest of the App */}
</HashRouter>
);
}
I'd like to add to @MBK's answer. Although I found @MBK's answer to be very helpful in solving a similar problem, it'd be better if @MBK included a screenshot of how to filter a particular column.

In the latest mongoose (3.8.1 at the time of writing), you do two things differently: (1) you have to pass single argument to sort(), which must be an array of constraints or just one constraint, and (2) execFind() is gone, and replaced with exec() instead. Therefore, with the mongoose 3.8.1 you'd do this:
var q = models.Post.find({published: true}).sort({'date': -1}).limit(20);
q.exec(function(err, posts) {
// `posts` will be of length 20
});
or you can chain it together simply like that:
models.Post
.find({published: true})
.sort({'date': -1})
.limit(20)
.exec(function(err, posts) {
// `posts` will be of length 20
});
It is safe to store your token in localStorage as long as you encrypt it. Below is a compressed code snippet showing one of many ways you can do it.
import SimpleCrypto from 'simple-crypto-js';
const saveToken = (token = '') => {
const encryptInit = new SimpleCrypto('PRIVATE_KEY_STORED_IN_ENV_FILE');
const encryptedToken = encryptInit.encrypt(token);
localStorage.setItem('token', encryptedToken);
}
Then, before using your token decrypt it using PRIVATE_KEY_STORED_IN_ENV_FILE
I needed to draw arbitrary diagonal lines inside any div. My issue with the other answers posted is that none of them allowed to draw an arbitrary line from point A to point B without doing the trigonometry yourself for the angles. With javascript & CSS you can do this. Hope it's helpful, just specify a pair of points and you're golden.

Andrea is correct. we can do it using command line.
And we still can program it, by
ZkClient zkClient = new ZkClient("localhost:2181", 10000);
zkClient.deleteRecursive(ZkUtils.getTopicPath("test2"));
Actually I do not recommend you delete topic on Kafka 0.8.1.1. I can delete this topic by this method, but if you check log for zookeeper, deletion mess it up.
For those trouble shooting, it is important to know that ng-include requires the url path to be from the app root directory and not from the same directory where the partial.html lives. (whereas partial.html is the view file that the inline ng-include markup tag can be found).
For example:
Correct: div ng-include src=" '/views/partials/tabSlides/add-more.html' ">
Incorrect: div ng-include src=" 'add-more.html' ">
You can use the ArrayUtils
class from commons-lang to obtain a double[]
from a Double[]
.
Double[] ds = frameList.toArray(new Double[frameList.size()]);
...
double[] d = ArrayUtils.toPrimitive(ds);
Keep it simple:
try:
from . import mymodule # "myapp" case
except:
import mymodule # "__main__" case
First install the JDK1.8 set to Path Open Eclipse and Oper Eclipse Market Place option. Search for jdk 1.8 for kepler Install the required plugin. Restart the eclipse. Change compiler level to 1.8 from preferences. If still there is an error then click on the file and change the compiler setting explicitly to Jdk 1.8
Create a segue to present modally and set Presentation property of that segue to over current context it will work 100 %
I did a small test a while back with a list vs a hashmap, funny thing was iterating through the list and finding the object took the same amount of time in milliseconds as using the hashmaps get function... just an fyi. Oh yeah memory is a big issue when working with hashmaps that size.
/*
If your delimiters are slash-based, escape it:
\/*
*
means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.
Check these steps.
this works for me:
v=$(cat <file_path>)
echo $v
In a few words:
With the help of the of Guido mail provided by @kindall, we can understand the standard import process as trying to find the module in each member of sys.path
, and file as the result of this lookup (more details in PyMOTW Modules and Imports.). So if the module is located in an absolute path in sys.path
the result is absolute, but if it is located in a relative path in sys.path
the result is relative.
Now the site.py
startup file takes care of delivering only absolute path in sys.path
, except the initial ''
, so if you don't change it by other means than setting the PYTHONPATH (whose path are also made absolute, before prefixing sys.path
), you will get always an absolute path, but when the module is accessed through the current directory.
Now if you trick sys.path in a funny way you can get anything.
As example if you have a sample module foo.py
in /tmp/
with the code:
import sys
print(sys.path)
print (__file__)
If you go in /tmp you get:
>>> import foo
['', '/tmp', '/usr/lib/python3.3', ...]
./foo.py
When in in /home/user
, if you add /tmp
your PYTHONPATH
you get:
>>> import foo
['', '/tmp', '/usr/lib/python3.3', ...]
/tmp/foo.py
Even if you add ../../tmp
, it will be normalized and the result is the same.
But if instead of using PYTHONPATH
you use directly some funny path
you get a result as funny as the cause.
>>> import sys
>>> sys.path.append('../../tmp')
>>> import foo
['', '/usr/lib/python3.3', .... , '../../tmp']
../../tmp/foo.py
Guido explains in the above cited thread, why python do not try to transform all entries in absolute paths:
we don't want to have to call getpwd() on every import .... getpwd() is relatively slow and can sometimes fail outright,
So your path is used as it is.
namespace TestCSharp2
{
**public** class Class2
{
int i;
public void setValue(int i)
{
this.i = i;
}
public int getValue()
{
return this.i;
}
}
}
Add the 'Public' declaration before 'class Class2'.
Your local branch likely has modifications to it you want to discard. To do this, you'll need to use git reset
to reset the branch head to the last spot that you diverged from the upstream repo's branch. Use git branch -v
to find the sha1 id of the upstream branch, and reset your branch it it using git reset SHA1ID
. Then you should be able to do a git checkout
to discard the changes it left in your directory.
Note: always do this on a backed-up repo. That way you can assure you're self it worked right. Or if it didn't, you have a backup to revert to.
According the google docs
this happened because the url
on which you are using the Google Maps API, it not registered
in list of allowed referrers
EDIT :
From Google Docs
All subdomains of a specified domain are also authorized.
If http://example.com is authorized, then http://www.example.com is also authorized. The reverse is not true: if http://www.example.com is authorized, http://example.com is not necessarily authorized
So,Please configure http://testdomain.com
domain, then your http://www.testdomain.com
will start work.
I couldn't find exactly what I was looking for so wrote something as basic as I could make it. The highlighted class could just be a background color.
var blinking = false; // global scope
function start_blinking() {
blinking = true;
blink();
}
function stop_blinking() {
blinking = false;
}
function blink(x=0) {
$("#element").removeClass("highlighted"); // default to not highlighted to account for the extra iteration after stopping
if (blinking) {
if (x%2 == 0) $("#element").addClass("highlighted"); // highlight on even numbers of x
setTimeout(function(){blink(++x)},500); // increment x and recurse
}
}
For whatever it's worth now: I did post a solution to a sister-thread Table scroll with HTML and CSS which
visibility
, not display
) the header of the lower table and make the lower table scrollable w/in a divThe solution is agnostic to any styles / frameworks used - so maybe it's useful here as well...
A long description is in Table scroll with HTML and CSS / the code is also in this pen: https://codepen.io/sebredhh/pen/QmJvKy
My answer is based on getting a 403 error although I had all of the Apache settings mentioned in the other answers correct.
It was a fresh Centos 7 server and it turned out that the issue was not the Apache settings but the fact that the PhpMyAdmin did not serve at all. The solution was to install php and add the php directive to apache.conf:
Don't forget to restart Apache server to take effect - systemctl restart httpd.service
I hope this helps. I first thought my issue was Apache directives, so I post my solution here.
You might want to check that library
**org.eclipse.equinox.launcher_(version).dist.jar**
and
**plugins/org.eclipse.equinox.launcher.gtk.linux.x86_(version).dist**
exists on your system.
Make sure that the version of libraries mentioned in eclipse.ini and the version that exists on your system is same. Usually after upgrade this mismatch occurs and eclipse fails to locate the required jar. Please take a look at this blog post here
I am not sure if this is the correct solution but I have achieved this by redefining .marquee class just after animation CSS.
Check below:
<style>
#marquee-wrapper{
width:700px;
display:block;
border:1px solid red;
}
div.marquee{
width:100px;
height:100px;
background:red;
position:relative;
animation:myfirst 5s;
-moz-animation:myfirst 5s; /* Firefox */
}
@-moz-keyframes myfirst /* Firefox */{
0% {background:red; left:0px; top:0px;}
100% {background:red; left:100%; top:0px}
}
div.marquee{
left:700px; top:0px
}
</style>
<!-- HTMl COde -->
<p><b>Note:</b> This example does not work in Internet Explorer and Opera.</p>
<div id="marquee-wrapper">
<div class="marquee"></div>
Other answers rightly point out that there is no need to use jQuery in order to navigate to another URL; that's why there's no jQuery function which does so!
If you're asking how to click a link via jQuery then assuming you have markup which looks like:
<a id="my-link" href="/relative/path.html">Click Me!</a>
You could click()
it by executing:
$('#my-link').click();
There are no decompilers which I know about. W32dasm is good Win32 disassembler.

Found the solution to this problem here: https://github.com/h5bp/html5-boilerplate/issues/378
Even though Sheena's answer does the job, pip
doesn't stop just there.
From Sheena's answer:
- Download the package
- unzip it if it is zipped
- cd into the directory containing setup.py
- If there are any installation instructions contained in documentation contained herein, read and follow the instructions OTHERWISE
- type in
python setup.py install
At the end of this, you'll end up with a .egg
file in site-packages
.
As a user, this shouldn't bother you. You can import
and uninstall
the package normally. However, if you want to do it the pip
way, you can continue the following steps.
In the site-packages
directory,
unzip <.egg file>
EGG-INFO
directory as <pkg>-<version>.dist-info
<pkg-directory>
find <pkg-directory> > <pkg>-<version>.dist-info/RECORD
find <pkg>-<version>.dist-info >> <pkg>-<version>.dist-info/RECORD
. The >>
is to prevent overwrite.Now, looking at the site-packages
directory, you'll never realize you installed without pip
. To uninstall
, just do the usual pip uninstall <pkg>
.
Session in Asp.net:
1.Maintains the data accross all over the application.
2.Persists the data if current session is alive. If we need some data to accessible from multiple controllers acitons and views the session is the way to store and retreive data.
3.Sessions are server side files that contains user information. [Sessions are unique identifier that maps them to specific users]
Translating that to Web Servers: The server will store the pertinent information in the session object, and create a session ID which it will send back to the client in a cookie. When the client sends back the cookie, the server can simply look up the session object using the ID. So, if you delete the cookie, the session will be lost.
Use this,
var currentDirectory = System.IO.Directory.GetCurrentDirectory();
You can use this as well.
var currentDirectory = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
You can define a method in spec_helper.rb that sends a message both to Rails.logger.info and to puts and use that for debugging:
def log_test(message)
Rails.logger.info(message)
puts message
end
Swift 4 updated :
extension UIView {
var screenShot: UIImage? {
if #available(iOS 10, *) {
let renderer = UIGraphicsImageRenderer(bounds: self.bounds)
return renderer.image { (context) in
self.layer.render(in: context.cgContext)
}
} else {
UIGraphicsBeginImageContextWithOptions(bounds.size, false, 5);
if let _ = UIGraphicsGetCurrentContext() {
drawHierarchy(in: bounds, afterScreenUpdates: true)
let screenshot = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return screenshot
}
return nil
}
}
}
it's simple just type : $facebook->setSession(null); for logout
Uncaught exception messages go to STDERR, so instead of implementing your logging in Python itself you could send STDERR to a file using whatever shell you're using to run your Python script. In a Bash script, you can do this with output redirection, as described in the BASH guide.
Append errors to file, other output to the terminal:
./test.py 2>> mylog.log
Overwrite file with interleaved STDOUT and STDERR output:
./test.py &> mylog.log
with UnionTable as
(
SELECT a.id, a.time FROM dbo.a
UNION
SELECT b.id, b.time FROM dbo.b
) SELECT id FROM UnionTable GROUP BY id
CSS3 has a pseudo-class called :not()
input:not([type='checkbox']) {
visibility: hidden;
}
_x000D_
<p>If <code>:not()</code> is supported, you'll only see the checkbox.</p>
<ul>
<li>text: (<input type="text">)</li>
<li>password (<input type="password">)</li>
<li>checkbox (<input type="checkbox">)</li>
</ul>
_x000D_
As Vincent mentioned, it's possible to string multiple :not()
s together:
input:not([type='checkbox']):not([type='submit'])
CSS4, which is supported in many of the latest browser releases, allows multiple selectors in a :not()
input:not([type='checkbox'],[type='submit'])
All modern browsers support the CSS3 syntax. At the time this question was asked, we needed a fall-back for IE7 and IE8. One option was to use a polyfill like IE9.js. Another was to exploit the cascade in CSS:
input {
// styles for most inputs
}
input[type=checkbox] {
// revert back to the original style
}
input.checkbox {
// for completeness, this would have worked even in IE3!
}
You can also do this:
try {
myView.getClass().getMethod(android.os.Build.VERSION.SDK_INT >= 16 ? "setBackground" : "setBackgroundDrawable", Drawable.class).invoke(myView, myBackgroundDrawable);
} catch (Exception ex) {
// do nothing
}
EDIT: Just as pointed out by @BlazejCzapp it is preferable to avoid using reflection if you can manage to solve the problem without it. I had a use case where I was unable to solve without reflection but that is not case above. For more information please take a look at http://docs.oracle.com/javase/tutorial/reflect/index.html

It seems that without return()
it's faster...
library(rbenchmark)
x <- 1
foo <- function(value) {
return(value)
}
fuu <- function(value) {
value
}
benchmark(foo(x),fuu(x),replications=1e7)
test replications elapsed relative user.self sys.self user.child sys.child
1 foo(x) 10000000 51.36 1.185322 51.11 0.11 0 0
2 fuu(x) 10000000 43.33 1.000000 42.97 0.05 0 0
____EDIT __________________
I proceed to others benchmark (benchmark(fuu(x),foo(x),replications=1e7)
) and the result is reversed... I'll try on a server.
This is quite old question, but I have had the exact same annoying issue where everything worked fine for Chrome/Edge (with object-fit property) but same css property did not work in IE11 (since its unsupported in IE11), I ended up using HTML5 "figure" element which solved all my problems.
I personally did not use the outer DIV tag since that did not help at all in my case, so I avoided the outer DIV and simply replaced with 'figure' element.
The below code forces the image to reduce/scale down nicely (without changing the original aspect ratio).
<figure class="figure-class">
<img class="image-class" src="{{photoURL}}" />
</figure>
and css classes:
.image-class {
border: 6px solid #E8E8E8;
max-width: 189px;
max-height: 189px;
}
.figure-class {
width: 189px;
height: 189px;
}
"Allocation Failure" is cause of GC to kick is not correct. It is an outcome of GC operation.
GC kicks in when there is no space to allocate( depending on region minor or major GC is performed). Once GC is performed if space is freed good enough, but if there is not enough size it fails. Allocation Failure is one such failure. Below document have good explanation https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/g1_gc.html
While I tried the approach above, it becomes a complete disaster with mvc. Your controller passing a model and your view using a strongly typed model become too difficult to work with.
Get your Dataset into a List ..... I have a repository pattern and here is an example of getting a dataset from an old school asmx web service private readonly CISOnlineSRVDEV.ServiceSoapClient _ServiceSoapClient;
public Get_Client_Repository()
: this(new CISOnlineSRVDEV.ServiceSoapClient())
{
}
public Get_Client_Repository(CISOnlineSRVDEV.ServiceSoapClient serviceSoapClient)
{
_ServiceSoapClient = serviceSoapClient;
}
public IEnumerable<IClient> GetClient(IClient client)
{
// **** Calling teh web service with passing in the clientId and returning a dataset
DataSet dataSet = _ServiceSoapClient.get_clients(client.RbhaId,
client.ClientId,
client.AhcccsId,
client.LastName,
client.FirstName,
"");//client.BirthDate.ToString()); //TODO: NEED TO FIX
// USE LINQ to go through the dataset to make it easily available for the Model to display on the View page
List<IClient> clients = (from c in dataSet.Tables[0].AsEnumerable()
select new Client()
{
RbhaId = c[5].ToString(),
ClientId = c[2].ToString(),
AhcccsId = c[6].ToString(),
LastName = c[0].ToString(), // Add another field called Sex M/F c[4]
FirstName = c[1].ToString(),
BirthDate = c[3].ToDateTime() //extension helper ToDateTime()
}).ToList<IClient>();
return clients;
}
Then in the Controller I'm doing this
IClient client = (IClient)TempData["Client"];
// Instantiate and instance of the repository
var repository = new Get_Client_Repository();
// Set a model object to return the dynamic list from repository method call passing in the parameter data
var model = repository.GetClient(client);
// Call the View up passing in the data from the list
return View(model);
Then in the View it is easy :
@model IEnumerable<CISOnlineMVC.DAL.IClient>
@{
ViewBag.Title = "CLIENT ALL INFORMATION";
}
<h2>CLIENT ALL INFORMATION</h2>
<table>
<tr>
<th></th>
<th>Last Name</th>
<th>First Name</th>
<th>Client ID</th>
<th>DOB</th>
<th>Gender</th>
<th>RBHA ID</th>
<th>AHCCCS ID</th>
</tr>
@foreach (var item in Model) {
<tr>
<td>
@Html.ActionLink("Select", "ClientDetails", "Cis", new { id = item.ClientId }, null) |
</td>
<td>
@item.LastName
</td>
<td>
@item.FirstName
</td>
<td>
@item.ClientId
</td>
<td>
@item.BirthDate
</td>
<td>
Gender @* ADD in*@
</td>
<td>
@item.RbhaId
</td>
<td>
@item.AhcccsId
</td>
</tr>
}
</table>
It's complicated.
First of all, in this code
const p = new Promise((resolve) => {
resolve(4);
});
the type of p
is inferred as Promise<{}>
. There is open issue about this on typescript github, so arguably this is a bug, because obviously (for a human), p
should be Promise<number>
.
Then, Promise<{}>
is compatible with Promise<number>
, because basically the only property a promise has is then
method, and then
is compatible in these two promise types in accordance with typescript rules for function types compatibility. That's why there is no error in whatever1
.
But the purpose of async
is to pretend that you are dealing with actual values, not promises, and then you get the error in whatever2
because {}
is obvioulsy not compatible with number
.
So the async
behavior is the same, but currently some workaround is necessary to make typescript compile it. You could simply provide explicit generic argument when creating a promise like this:
const whatever2 = async (): Promise<number> => {
return new Promise<number>((resolve) => {
resolve(4);
});
};
That's not how you send file on postman. What you did is sending a string which is the path of your image, nothing more.
What you should do is;
You're ready to go.
In your Django view,
from rest_framework.views import APIView
from rest_framework.parsers import MultiPartParser
from rest_framework.decorators import parser_classes
@parser_classes((MultiPartParser, ))
class UploadFileAndJson(APIView):
def post(self, request, format=None):
thumbnail = request.FILES["file"]
info = json.loads(request.data['info'])
...
return HttpResponse()
If you're having problems on windows like me (I'm using Windows 7 64-bit) and set PGPASSWORD=[Password]
did not work.
Then, as Kavaklioglu said in one of the comments,
export PGPASSWORD=[password]
You will need to save this at the top of the file, or before any usage so its set before being called.
Certainly does work on windows :)
In C int foo()
and int foo(void)
are different functions. int foo()
accepts an arbitrary number of arguments, while int foo(void)
accepts 0 arguments. In C++ they mean the same thing. I suggest that you use void
consistently when you mean no arguments.
If you have a variable a
, extern int a;
is a way to tell the compiler that a
is a symbol that might be present in a different translation unit (C compiler speak for source file), don't resolve it until link time. On the other hand, symbols which are function names are anyway resolved at link time. The meaning of a storage class specifier on a function (extern
, static
) only affects its visibility and extern
is the default, so extern
is actually unnecessary.
I suggest removing the extern
, it is extraneous and is usually omitted.
You can achieve quite a cool custom checkbox effect by using the new abilities that come with the :after
and :before
pseudo classes. The advantage to this, is: You don't need to add anything more to the DOM, just the standard checkbox.
Note this will only work for compatible browsers. I believe this is related to the fact that some browsers do not allow you to set :after
and :before
on input elements. Which unfortunately means for the moment only WebKit browsers are supported. Firefox + Internet Explorer will still allow the checkboxes to function, just unstyled, and this will hopefully change in the future (the code does not use vendor prefixes).
This is a WebKit browser solution only (Chrome, Safari, Mobile browsers)

It is better to use onchange(event)
with <select>
.
With <input>
you can use below event:
- onkeyup(event)
- onkeydown(event)
- onkeypress(event)
It will work when you put your annotation before the getters, and remove it from the protected attributes:
protected String codingScheme;
@XmlAttribute(name = "codingScheme")
public String getCodingScheme() {
return this.codingScheme;
}
On controller.
$your_variable = '';
$your_variable .= '<p>Hello world</p>';
return view('viewname')->with('your_variable', $your_variable)
If you do not want your data to be escaped, you may use the following syntax:
{!! $your_variable !!}
Output
Hello world
jQuery's underlying code passes these strings to the DOM, which allows you to specify the CSS property name or the DOM property name in a very similar way:
element.style.marginLeft = "10px";
is equivalent to:
element.style["margin-left"] = "10px";
Why has jQuery allowed for marginLeft as well as margin-left? It seems pointless and uses more resources to be converted to the CSS margin-left?
jQuery's not really doing anything special. It may alter or proxy some strings that you pass to .css()
, but in reality there was no work put in from the jQuery team to allow either string to be passed. There's no extra resources used because the DOM does the work.
The answer is: for no good reason whatsoever.
Contrary to its name, the XmlSerializer
class is used not only for serialization, but also for deserialization. It performs certain checks on your class to make sure that it will work, and some of those checks are only pertinent to deserialization, but it performs them all anyway, because it does not know what you intend to do later on.
The check that your class fails to pass is one of the checks that are only pertinent to deserialization. Here is what happens:
During deserialization, the XmlSerializer
class will need to create
instances of your type.
In order to create an instance of a type, a constructor of that type needs to be invoked.
If you did not declare a constructor, the compiler has already supplied a default parameterless constructor, but if you did declare a constructor, then that's the only constructor available.
So, if the constructor that you declared accepts parameters, then the only way to instantiate your class is by invoking that constructor which accepts parameters.
However, XmlSerializer
is not capable of invoking any constructor
except a parameterless constructor, because it does not know what
parameters to pass to constructors that accept parameters. So, it checks to see if your class has a parameterless constructor, and since it does not, it fails.
So, if the XmlSerializer
class had been written in such a way as to only perform the checks pertinent to serialization, then your class would pass, because there is absolutely nothing about serialization that makes it necessary to have a parameterless constructor.
As others have already pointed out, the quick solution to your problem is to simply add a parameterless constructor. Unfortunately, it is also a dirty solution, because it means that you cannot have any readonly
members initialized from constructor parameters.
In addition to all this, the XmlSerializer
class could have been written in such a way as to allow even deserialization of classes without parameterless constructors. All it would take would be to make use of "The Factory Method Design Pattern" (Wikipedia). From the looks of it, Microsoft decided that this design pattern is far too advanced for DotNet programmers, who apparently should not be unnecessarily confused with such things. So, DotNet programmers should better stick to parameterless constructors, according to Microsoft.
Both can be invoked without instantiation, both provide only one "Instance" and neither of them is thread-safe. Is there any other difference?
The question is wrong, both its statements. Please note: that static class here means nested static class And not a class with only static methods.
I am assuming(i.e. static class meaning nested static class and not a class with only static members) so because if I see most popular Singleton implementation i.e. DCL way, its nothing but static declaration of instance and static method to get the Singleton instance. Its one implementation. So in this case what's the difference between Singleton and a class with only static members. Though other implementations are possible like that using Enum.
Let me correct the statements:
Singleton class can have single instance application-wide. Nested static class can have multiple instance(see the code below as a proof). Read the basics of nested class here.
No class is inherently thread-safe, it has to be made thread-safe programmatically. It can be done for both nested static class and Singleton.
Some more myth busters are below(Most of answers to this question has given these statements so thought it would be good to programmatically prove it):
In the code below you can see that nested static class NestedStaticClass implements interface, extends another class, have instance variable and parameterized constructor.
package com.demo.core;
public class NestedStaticClassTest
{
public static void main(String[] args)
{
OuterClass.NestedStaticClass obj1 = new OuterClass.NestedStaticClass();
OuterClass.NestedStaticClass obj2 = new OuterClass.NestedStaticClass();
if(obj1 == obj2)
{
System.out.println("Both nested static objects are equal....");
}
else
{
System.out.println("NOT EQUAL......");
}
System.out.println(OuterClass.NestedStaticClass.d);
obj1.setD(5);
System.out.println(OuterClass.NestedStaticClass.d);
System.out.println(obj1.sum());
}
}
class OuterClass
{
int a =1;
static int b = 2;
static class NestedStaticClass extends OneClass implements Sample
{
int c = 3;
static int d = 4;
public NestedStaticClass()
{
}
//Parameterized constructor
public NestedStaticClass(int z)
{
c = z;
}
public int sum()
{
int sum = 0;
sum = b + c + d + getE();
return sum;
}
public static int staticSum()
{
int sum = 0;
sum = b + d;
return sum;
}
public int getC()
{
return c;
}
public void setC(int c)
{
this.c = c;
}
public static int getD()
{
return d;
}
public static void setD(int d)
{
NestedStaticClass.d = d;
}
}
}
interface Sample
{
}
class OneClass
{
int e = 10;
static int f = 11;
public int getE()
{
return e;
}
public void setE(int e)
{
this.e = e;
}
public static int getF()
{
return f;
}
public static void setF(int f)
{
OneClass.f = f;
}
}
Here is a slightly different implementation of an AJAX cache as in ehynd's answer.
As noted in fortuneRice's follow-up question, ehynd's implementation didn't actually prevent multiple identical requests if the requests were performed before one of them had returned. That is,
for (var i=0; i<3; i++) {
getData("xxx");
}
will most likely result in 3 AJAX requests if the result for "xxx" has not already been cached before.
This can be solved by caching the request's Deferreds instead of the result:
var cache = {};
function getData( val ){
// Return a promise from the cache (if available)
// or create a new one (a jqXHR object) and store it in the cache.
var promise = cache[val];
if (!promise) {
promise = $.ajax('/foo/', {
data: { value: val },
dataType: 'json'
});
cache[val] = promise;
}
return promise;
}
$.when(getData('foo')).then(function(resp){
// do something with the response, which may
// or may not have been retreived using an
// XHR request.
});
"variables declared implicitly" are properties of the global object, so delete works on them like it works on any property. Variables declared with var are indestructible.
For next examples assumed that you use C++11. Example with ranged-based for loops:
for (auto &attack : m_attack) // access by reference to avoid copying
{
if (attack->m_num == input)
{
attack->makeDamage();
}
}
You should use const auto &attack
depending on the behavior of makeDamage()
.
You can use std::for_each
from standard library + lambdas:
std::for_each(m_attack.begin(), m_attack.end(),
[](Attack * attack)
{
if (attack->m_num == input)
{
attack->makeDamage();
}
}
);
If you are uncomfortable using std::for_each
, you can loop over m_attack
using iterators:
for (auto attack = m_attack.begin(); attack != m_attack.end(); ++attack)
{
if (attack->m_num == input)
{
attack->makeDamage();
}
}
Use m_attack.cbegin()
and m_attack.cend()
to get const
iterators.
You're returning the address of a local variable allocated on the stack. When your function returns, the storage for all local variables (such as wc
) is deallocated and is subject to being immediately overwritten by something else.
To fix this, you can pass the size of the buffer to GetWC
, but then you've got pretty much the same interface as mbstowcs
itself. Or, you could allocate a new buffer inside GetWC
and return a pointer to that, leaving it up to the caller to deallocate the buffer.
FYI this kind of code works (you can find it ugly, it is your right :) ) :
def list = null
list.each { println it }
soSomething()
In other words, this code has null/empty checks both useless:
if (members && !members.empty) {
members.each { doAnotherThing it }
}
def doAnotherThing(def member) {
// Some work
}
Just use Hour
and Minute
properties
var date = DateTime.Now;
date.Hour;
date.Minute;
Or you can easily zero the seconds using
var zeroSecondDate = date.AddSeconds(-date.Second);
I believe prestomanifesto was on the right track. It depends on what kind of element it is. You would need to use element.get_attribute('value')
for input elements and element.text
to return the text node of an element.
You could check the WebElement object with element.tag_name
to find out what kind of element it is and return the appropriate value.
This should help you figure out:
driver = webdriver.Firefox()
driver.get('http://www.w3c.org')
element = driver.find_element_by_name('q')
element.send_keys('hi mom')
element_text = element.text
element_attribute_value = element.get_attribute('value')
print element
print 'element.text: {0}'.format(element_text)
print 'element.get_attribute(\'value\'): {0}'.format(element_attribute_value)
driver.quit()
Change the date range to "General" format and save the workbook once, and change them back to date format (eg, numberformat = "d/m/yyyy"
) before save & close the book. savechanges
parameter is true.
Export you Java Project as an Runnable Jar file rather than Jar.
I exported my project as Jar and even though the Manifest was present it gave me the error no main manifest attribute in jar even though the Manifest file was present in the Jar. However there is only one entry in the Manifest file and it didn't specify the Main class or Function to execute or any dependent JAR's
After exporting it as Runnable Jar file it works as expected.
Why not apply the border to the bottom of the UL?

While the question has been answered in general, I've found myself that there's a case when even existing known_hosts entry doesn't help. This happens when an SSH server sends ECDSA fingerprint and as a result, you'll have an entry like this:
|1|+HASH=|HASH= ecdsa-sha2-nistp256 FINGERPRINT=
The problem is that JSch prefers SHA_RSA and while connecting it will try to compare SHA-RSA fingerprint, which will result with error about "unknown host".
To fix this simply run:
$ ssh-keyscan -H -t rsa example.org >> known_hosts
or complain to Jcraft about prefering SHA_RSA instead of using the local HostKeyAlgorithms setting, although they don't seem to be too eager to fix their bugs.
Since 10.0.2.2

Try adding this line before your dialog line.
$( "#dialog" ).dialog( "open" );
This method worked for me. It seems that the "close" command messes up the dialog opening again with only the .dialog() .
Using your code as an example, it would go in like this (note that you may need to add more to your code for it to make sense):
<script type="text/javascript">
$(document).ready(function() {
//$('#dialog').dialog();
$('#dialog_link').click(function() {
$( "#dialog" ).dialog( "open" );
$('#dialog').dialog();
return false;
});
});
</script>
</head><body>
<div id="dialog" title="Dialog Title" style="display:none"> Some text</div>
<p id="dialog_link">Open Dialog</p>
</body></html>
Following code works for me.
$("body").on('DOMSubtreeModified', "mydiv", function() {
alert('changed');
});
Hope it will help someone :)
The default value of "spark.master" is spark://HOST:PORT, and the following code tries to get a session from the standalone cluster that is running at HOST:PORT, and expects the HOST:PORT value to be in the spark config file.
SparkSession spark = SparkSession
.builder()
.appName("SomeAppName")
.getOrCreate();
"org.apache.spark.SparkException: A master URL must be set in your configuration" states that HOST:PORT is not set in the spark configuration file.
To not bother about value of "HOST:PORT", set spark.master as local
SparkSession spark = SparkSession
.builder()
.appName("SomeAppName")
.config("spark.master", "local")
.getOrCreate();
Here is the link for list of formats in which master URL can be passed to spark.master

You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like
$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");
You can confirm this by printing out the string to see that it turns out identical to the first case.
Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string
, which would make it look perhaps like this:
$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
mysql_real_escape_string($prefix));
$query = mysql_query($sql);
Note that inside the first argument of sprintf
the percent sign needs to be doubled to end up appearing once in the result.

This code you can write in Aspx. If you want this in some js.file, you have two ways:
SELECT CASE
WHEN transaction_isolation_level = 1
THEN 'READ UNCOMMITTED'
WHEN transaction_isolation_level = 2
AND is_read_committed_snapshot_on = 1
THEN 'READ COMMITTED SNAPSHOT'
WHEN transaction_isolation_level = 2
AND is_read_committed_snapshot_on = 0 THEN 'READ COMMITTED'
WHEN transaction_isolation_level = 3
THEN 'REPEATABLE READ'
WHEN transaction_isolation_level = 4
THEN 'SERIALIZABLE'
WHEN transaction_isolation_level = 5
THEN 'SNAPSHOT'
ELSE NULL
END AS TRANSACTION_ISOLATION_LEVEL

CROSS JOIN sys.databases AS d
WHERE session_id = @@SPID
AND d.database_id = DB_ID();
Now it works ok from CodeIgniter 2.1.0

$config['allow_get_array'] = TRUE;
If you have the Adblock extension, make sure you add the domain into the exception list. I had that problem with Google Analytics
It seems that OpenQA, guys behind Selenium, have already addressed this problem. They defined some variables to explicitely match whitespaces. In my case, I need to use an XPATH similar to //td[text()="${nbsp}"]
.
I reproduced here the text from OpenQA concerning this issue (found here):
HTML automatically normalizes whitespace within elements, ignoring leading/trailing spaces and converting extra spaces, tabs and newlines into a single space. When Selenium reads text out of the page, it attempts to duplicate this behavior, so you can ignore all the tabs and newlines in your HTML and do assertions based on how the text looks in the browser when rendered. We do this by replacing all non-visible whitespace (including the non-breaking space "
") with a single space. All visible newlines (<br>
,<p>
, and<pre>
formatted new lines) should be preserved.We use the same normalization logic on the text of HTML Selenese test case tables. This has a number of advantages. First, you don't need to look at the HTML source of the page to figure out what your assertions should be; "
" symbols are invisible to the end user, and so you shouldn't have to worry about them when writing Selenese tests. (You don't need to put "
" markers in your test case to assertText on a field that contains "
".) You may also put extra newlines and spaces in your Selenese<td>
tags; since we use the same normalization logic on the test case as we do on the text, we can ensure that assertions and the extracted text will match exactly.This creates a bit of a problem on those rare occasions when you really want/need to insert extra whitespace in your test case. For example, you may need to type text in a field like this: "
foo
". But if you simply write<td>foo </td>
in your Selenese test case, we'll replace your extra spaces with just one space.This problem has a simple workaround. We've defined a variable in Selenese,
${space}
, whose value is a single space. You can use${space}
to insert a space that won't be automatically trimmed, like this:<td>foo${space}${space}${space}</td>
. We've also included a variable${nbsp}
, that you can use to insert a non-breaking space.Note that XPaths do not normalize whitespace the way we do. If you need to write an XPath like
//div[text()="hello world"]
but the HTML of the link is really "hello world

Variable number of arguments
It is possible to pass a variable number of arguments to a method. However, there are some restrictions:
To understand these restrictions, consider the method, in the following code snippet, used to return the largest integer in a list of integers:
private static int largest(int... numbers) {
int currentLargest = numbers[0];
for (int number : numbers) {
if (number > currentLargest) {
currentLargest = number;
}
}
return currentLargest;
}

When you define a Foreign Key in table B referencing the Primary Key of table A it means that when a value is in B, it must be in A. This is to prevent unconsistent modifications to the tables.
In your example, your tables contain:
tblDomare with PRIMARY KEY (PersNR)
:
PersNR |fNamn |eNamn |Erfarenhet
-----------|----------|-----------|----------
6811034679 |'Bengt' |'Carlberg' |10
7606091347 |'Josefin' |'Backman' |4
8508284163 |'Johanna' |'Backman' |1
---------------------------------------------
tblBana:
BanNR
-----
1
2
3
-----
This statement:
ALTER TABLE tblDomare
ADD FOREIGN KEY (PersNR)
REFERENCES tblBana(BanNR);
says that any line in tblDomare
with key PersNR
must have a correspondence in table tblBana
on key BanNR
. Your error is because you have lines inserted in tblDomare
with no correspondence in tblBana
.
2 solutions to fix your issue:
tblBana
with BanNR in (6811034679, 7606091347, 8508284163)tblDomare
that have no correspondence in tblBana
(but your table would be empty)General advice: you should have the Foreign Key constraint before populating the tables. Foreign keys are here to prevent the user of the table from filling the tables with inconsistencies.
Just document it here

Yes, this is an old question. But it's misleading, as this was the first result in my search, and both the answers aren't correct anymore.
You can change your Github account name at any time.
To do this, click your profile picture > Settings
> Account Settings
> Change Username
.
Links to your repositories will redirect to the new URLs, but they should be updated on other sites because someone who chooses your abandoned username can override the links. Links to your profile page will be 404'd.
For more information, see the official help page.
And furthermore, if you want to change your username to something else, but that specific username is being taken up by someone else who has been completely inactive for the entire time their account has existed, you can report their account for name squatting.
You should use thenReturn
or doReturn
when you know the return value at the time you mock a method call. This defined value is returned when you invoke the mocked method.
thenReturn(T value)
Sets a return value to be returned when the method is called.
@Test
public void test_return() throws Exception {
Dummy dummy = mock(Dummy.class);
int returnValue = 5;
// choose your preferred way
when(dummy.stringLength("dummy")).thenReturn(returnValue);
doReturn(returnValue).when(dummy).stringLength("dummy");
}
Answer
is used when you need to do additional actions when a mocked method is invoked, e.g. when you need to compute the return value based on the parameters of this method call.
Use
doAnswer()
when you want to stub a void method with genericAnswer
.Answer specifies an action that is executed and a return value that is returned when you interact with the mock.
@Test
public void test_answer() throws Exception {
Dummy dummy = mock(Dummy.class);
Answer<Integer> answer = new Answer<Integer>() {
public Integer answer(InvocationOnMock invocation) throws Throwable {
String string = invocation.getArgumentAt(0, String.class);
return string.length() * 2;
}
};
// choose your preferred way
when(dummy.stringLength("dummy")).thenAnswer(answer);
doAnswer(answer).when(dummy).stringLength("dummy");
}

I tried this as a best guess, but no luck:
It looks right to me. Have you tried setting a message severity explicitly? Also I believe the ID needs to be the same as that of a component (i.e., you'd need to use newPassword1 or newPassword2, if those are your IDs, and not newPassword as you had in the example).
FacesContext.getCurrentInstance().addMessage("newPassword1",
new FacesMessage(FacesMessage.SEVERITY_ERROR, "Error Message"));
Then use <h:message for="newPassword1" />
to display the error message on the JSF page.
The same way with '\n'
, though you'd probably not need the '\r'
. Is there a reason you have it in your Java version? If you do need/want it, you can use it in the same way in Python too.
changing 'Citable docs per Capita' to numeric before correlation will solve the problem.

correlation = data.corr(method='pearson')

I know this is an older question, but I wanted to post an answer for users with the same question:
curl -H 'Cache-Control: no-cache' http://www.example.com
This curl command servers in its header request to return non-cached data from the web server.
No. Mostly because it's of a rather niche need, and there are too many possible variations. (Is it "KB", "Kb" or "Ko"? Is a megabyte 1024 * 1024 bytes, or 1024 * 1000 bytes? -- yes, some places use that!)
The advantage of IEnumerable is deferred execution (usually with databases). The query will not get executed until you actually loop through the data. It's a query waiting until it's needed (aka lazy loading).
If you call ToList, the query will be executed, or "materialized" as I like to say.
There are pros and cons to both. If you call ToList, you may remove some mystery as to when the query gets executed. If you stick to IEnumerable, you get the advantage that the program doesn't do any work until it's actually required.
I use this vanilla JS solution:
const element = document.getElementById('textfield')
element.addEventListener('paste', e => e.preventDefault())
<script>
var listh = document.getElementById( 'list-home-list' );
var hb = document.getElementsByTagName('hb');
$("#list-home-list").click(function(){
$(this).style.color = '#2C2E33';
hb.style.color = 'white';
});
</script>
As an addition to other answers, unix considers everything as a file system. Your keyboard is a file that is read only from the perspective of the kernel. The screen is a write only file. Similarly, folders, input-output devices etc are also considered to be files. Whenever a file is opened, say when the device drivers[for device files] requests an open(), or a process opens an user file the kernel allocates a file descriptor, an integer that specifies the access to that file such it being read only, write only etc. [for reference : https://en.wikipedia.org/wiki/Everything_is_a_file ]
Here you have one nice and simple recursion for deleting all files in source directory including that directory:
function delete_dir($src) {
$dir = opendir($src);
while(false !== ( $file = readdir($dir)) ) {
if (( $file != '.' ) && ( $file != '..' )) {
if ( is_dir($src . '/' . $file) ) {
delete_dir($src . '/' . $file);
}
else {
unlink($src . '/' . $file);
}
}
}
closedir($dir);
rmdir($src);
}
Function is based on recursion made for copying directory. You can find that function here: Copy entire contents of a directory to another using php
Let me show to you all my experience with that.
I had an query that returned 32k of records, for each record I called a method to format that database record into a formated string and than concatenate that into a String that at the end of all this process wil turn into a file in disk.
My problem was that by the record goes, around 24k, the process of concatenating the String turned on a pain.
I was doing that using the regular '+' operator.
When I changed to the '<<' was like magic. Was really fast.
So, I remembered my old times - sort of 1998 - when I was using Java and concatenating String using '+' and changed from String to StringBuffer (and now we, Java developer have the StringBuilder).
I believe that the process of + / << in Ruby world is the same as + / StringBuilder.append in the Java world.
The first reallocate the entire object in memory and the other just point to a new address.
If I understand you correctly, You have two folders, one houses your php script that you want to include
into a file that is in another folder?
If this is the case, you just have to follow the trail the right way. Let's assume your folders are set up like this:
root
includes
php_scripts
script.php
blog
content
index.php
If this is the proposed folder structure, and you are trying to include the "Script.php" file into your "index.php" folder, you need to include it this way:
include("../../../includes/php_scripts/script.php");
The way I do it is visual. I put my mouse pointer on the index.php (looking at the file structure), then every time I go UP a folder, I type another "../" Then you have to make sure you go UP the folder structure ABOVE the folders that you want to start going DOWN into. After that, it's just normal folder hierarchy.
To answer your question, yes you may pass JSON in the URI as part of a GET request (provided you URL-encode). However, considering your reason for doing this is due to the length of the URI, using JSON will be self-defeating (introducing more characters than required).
I suggest you send your parameters in body of a POST request, either in regular CGI style (param1=val1¶m2=val2
) or JSON (parsed by your API upon receipt)
In the Lisp we did it this way:
> l <- c(1)
> l <- c(2, l)
> l <- c(3, l)
> l <- rev(l)
> l
[1] 1 2 3
though it was 'cons', not just 'c'. If you need to start with an empy list, use l <- NULL.
I'm not really sure if this adds anything but,
Caller saved means that the caller has to save the registers because they will be clobbered in the call and have no choice but to be left in a clobbered state after the call returns (for instance, the return value being in eax
for cdecl. It makes no sense for the return value to be restored to the value before the call by the callee, because it is a return value).
Callee saved means that the callee has to save the registers and then restore them at the end of the call because they have the guarantee to the caller of containing the same values after the function returns, and it is possible to restore them, even if they are clobbered at some point during the call.
The issue with the above definition though is that for instance on Wikipedia cdecl, it says eax
, ecx
and edx
are caller saved and rest are callee saved, this suggests that the caller must save all 3 of these registers, when it might not if none of these registers were used by the caller in the first place. In which case caller 'saved' becomes a misnomer, but 'call clobbered' still correctly applies. This is the same with 'the rest' being called callee saved. It implies that all other x86 registers will be saved and restored by the callee when this is not the case if some of the registers are never used in the call anyway. With cdecl, eax:edx
may be used to return a 64 bit value. I'm not sure why ecx
is also caller saved if needed, but it is.

Here is a way to handle duplicate tuple "keys":
# An example
l = [('A', 1), ('B', 2), ('C', 3), ('A', 5), ('D', 0), ('D', 9)]
# A solution
d = dict()
[d [t [0]].append(t [1]) if t [0] in list(d.keys())
else d.update({t [0]: [t [1]]}) for t in l]
d
OUTPUT: {'A': [1, 5], 'B': [2], 'C': [3], 'D': [0, 9]}
I'm not sure how you could just check if something isn't undefined and at the same time get an error that it is undefined. What browser are you using?
You could check in the following way (extra = and making length a truthy evaluation)
if (typeof(sub.from) !== 'undefined' && sub.from.length) {
[update]
I see that you reset sub and thereby reset sub.from but fail to re check if sub.from exist:
for (var i = 0; i < sub.from.length; i++) {//<== assuming sub.from.exist
mainid = sub.from[i]['id'];
var sub = afcHelper_Submissions[mainid]; // <== re setting sub
My guess is that the error is not on the if statement but on the for(i...
statement. In Firebug you can break automatically on an error and I guess it'll break on that line (not on the if statement).
Here's a general procedure for producing a random number in a specified range:
int randInRange(int min, int max)
{
return min + (int) (rand() / (double) (RAND_MAX + 1) * (max - min + 1));
}
Depending on the PRNG algorithm being used, the %
operator may result in a very non-random sequence of numbers.
However, one approach to dividing the dataset into train
, test
, cv
with 0.6
, 0.2
, 0.2
would be to use the train_test_split
method twice.
from sklearn.model_selection import train_test_split
x, x_test, y, y_test = train_test_split(xtrain,labels,test_size=0.2,train_size=0.8)
x_train, x_cv, y_train, y_cv = train_test_split(x,y,test_size = 0.25,train_size =0.75)

* The cost to add or delete an element into a known location in the list
(i.e. if you have an iterator to the location) is O(1). If you don't
know the location, then you need to traverse the list to the location
of deletion/insertion, which takes O(n) time.
** The deletion cost is O(log n) for the minimum or maximum, O(n) for an
arbitrary element.
I'll just add that I have tried to resolve reference problems caused by a missing library in the cache, and deleting the cache was not enough to solve the problem.
I closed NetBeans (7.2.1), deleted the cache, then reopened NetBeans, and it regenerated the cache, but the library was still missing (checked by looking in .../Cache/7.2.1/index/archives.properties).
To resolve the problem I had to close my open projects before closing NetBeans and deleting the cache.
You could use a second associative array that maps human readable names to the id's. That would also provide a Many to 1 relationship. Then do something like this:
echo 'Widgets: ' . $data[$humanreadbleMapping['Widgets']];
This question may be old but the answer is really simple using a TextWatcher.
int lastSize=0;
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
//2. compare the old length of the text with the new one
//3. if the length is shorter, then backspace was clicked
if (lastSize > charSequence.length()) {
//4. Backspace was clicked
//5. perform action
}
//1. get the current length of of the text
lastSize = charSequence.length();
}
<?php //-- Very simple variant
$useragent = $_SERVER['HTTP_USER_AGENT'];
$iPod = stripos($useragent, "iPod");
$iPad = stripos($useragent, "iPad");
$iPhone = stripos($useragent, "iPhone");
$Android = stripos($useragent, "Android");
$iOS = stripos($useragent, "iOS");
//-- You can add billion devices
$DEVICE = ($iPod||$iPad||$iPhone||$Android||$iOS||$webOS||$Blackberry||$IEMobile||$OperaMini);
if ($DEVICE !=true) {?>
<!-- What you want for all non-mobile devices. Anything with all HTML codes-->
<?php }else{ ?>
<!-- What you want for all mobile devices. Anything with all HTML codes -->
<?php } ?>
a = [1, 2, 2, 3, 1]
to_remove = 1
a = [i for i in a if i != to_remove]
print(a)
Perhaps not the most pythonic but still the easiest for me haha
You have to upgrade your subversion client to at least 1.7.
With the command line client, you have to manually upgrade your working copy format by issuing the command svn upgrade
:
Upgrading the Working Copy
Subversion 1.7 introduces substantial changes to the working copy format. In previous releases of Subversion, Subversion would automatically update the working copy to the new format when a write operation was performed. Subversion 1.7, however, will make this a manual step. Before using Subversion 1.7 with their working copies, users will be required to run a new command,
svn upgrade
to update the metadata to the new format. This command may take a while, and for some users, it may be more practical to simply checkout a new working copy.
— Subversion 1.7 Release Notes
TortoiseSVN will perform the working copy upgrade with the next write operation:

Before you can use an existing working copy with TortoiseSVN 1.7, you have to upgrade the format first. If you right-click on an old working copy, TortoiseSVN only shows you one command in the context menu: Upgrade working copy.

The numbers generated by

are uniformally distributed. If you want the numbers to be normally distributed, you will have to write a function I guess.
I usually take a slightly different track to achieve this:
$startTime = date("H:i",time() - 1800);
$endTime = date("H:i",time() + 1800);
Where 1800 seconds = 30 minutes.

Personally, I use ... | Out-Null
because, as others have commented, that looks like the more "PowerShellish" approach compared to ... > $null
and [void] ...
. $null = ...
is exploiting a specific automatic variable and can be easy to overlook, whereas the other methods make it obvious with additional syntax that you intend to discard the output of an expression. Because ... | Out-Null
and ... > $null
come at the end of the expression I think they effectively communicate "take everything we've done up to this point and throw it away", plus you can comment them out easier for debugging purposes (e.g. ... # | Out-Null
), compared to putting $null =
or [void]
before the expression to determine what happens after executing it.
Let's look at a different benchmark, though: not the amount of time it takes to execute each option, but the amount of time it takes to figure out what each option does. Having worked in environments with colleagues who were not experienced with PowerShell or even scripting at all, I tend to try to write my scripts in a way that someone coming along years later that might not even understand the language they're looking at can have a fighting chance at figuring out what it's doing since they might be in a position of having to support or replace it. This has never occurred to me as a reason to use one method over the others until now, but imagine you're in that position and you use the help
command or your favorite search engine to try to find out what Out-Null
does. You get a useful result immediately, right? Now try to do the same with [void]
and $null =
. Not so easy, is it?
Granted, suppressing the output of a value is a pretty minor detail compared to understanding the overall logic of a script, and you can only try to "dumb down" your code so much before you're trading your ability to write good code for a novice's ability to read...not-so-good code. My point is, it's possible that some who are fluent in PowerShell aren't even familiar with [void]
, $null =
, etc., and just because those may execute faster or take less keystrokes to type, doesn't mean they're the best way to do what you're trying to do, and just because a language gives you quirky syntax doesn't mean you should use it instead of something clearer and better-known.*
* I am presuming that Out-Null
is clear and well-known, which I don't know to be $true
. Whichever option you feel is clearest and most accessible to future readers and editors of your code (yourself included), regardless of time-to-type or time-to-execute, that's the option I'm recommending you use.

Another thing to check is whether you have Windows Firewall enabled, since that might be blocking port 42424.
If you want the form to be submitted on the same page then remove the action
from the form attributes.
<form method="POST" name="myform">
<!-- Your HTML code Here -->
</form>
However, If you want to reload the page or redirect the page after submitting the form from another file then you call this function in php
and it will redirect the page in 0 seconds. Also, You can use the header
if you want to, just make sure you don't have any content before using the header
function page_redirect($location)
{
echo '<META HTTP-EQUIV="Refresh" Content="0; URL='.$location.'">';
exit;
}
// I want the page to go to google.
// page_redirect("http://www.google.com")
Another way is to get the row index and then use df.loc or df.at.
# get row index 'label' from row number 'irow'
label = df.index.values[irow]
df.at[label, 'COL_NAME'] = x
After trying all these procedures it still didn't work for me. What did work was
Our current work required integrating a number of disparate projects so unfortunately use of SNAPSHOTs in a production environment were required (taboo in Maven circles)!
If you can be sure to have precise alignment of your template (the icon) to the testing region, then any old sum of pixel differences will work.
If the alignment is only going to be a tiny bit off, then you can low-pass both images with cv::GaussianBlur before finding the sum of pixel differences.
If the quality of the alignment is potentially poor then I would recommend either a Histogram of Oriented Gradients or one of OpenCV's convenient keypoint detection/descriptor algorithms (such as SIFT or SURF).
bundle exec
is a Bundler command to execute a script in the context of the current bundle (the one from your directory's Gemfile). rake db:migrate
is the script where db is the namespace and migrate is the task name defined.
So bundle exec rake db:migrate
executes the rake script with the command db:migrate
in the context of the current bundle.
As to the "why?" I'll quote from the bundler page:
In some cases, running executables without
bundle exec
may work, if the executable happens to be installed in your system and does not pull in any gems that conflict with your bundle.However, this is unreliable and is the source of considerable pain. Even if it looks like it works, it may not work in the future or on another machine.
If you are already using an OutputStream
to write to the socket, then DataOutputStream might be a good fit. Here is an example:
// Assumes you are currently working with a SocketOutputStream.
SocketOutputStream outputStream = ...
long longValue = ...
DataOutputStream dataOutputStream = new DataOutputStream(outputStream);
dataOutputStream.writeLong(longValue);
dataOutputStream.flush();
There are similar methods for short
, int
, float
, etc. You can then use DataInputStream on the receiving side.
If you want to disable a single transition property, you can do:
transition: color 0s;
(since a zero second transition is the same as no transition.)
Here's a cross browser function I have in my standard library:
function getCursorPos(input) {
if ("selectionStart" in input && document.activeElement == input) {
return {
start: input.selectionStart,
end: input.selectionEnd
};
}
else if (input.createTextRange) {
var sel = document.selection.createRange();
if (sel.parentElement() === input) {
var rng = input.createTextRange();
rng.moveToBookmark(sel.getBookmark());
for (var len = 0;
rng.compareEndPoints("EndToStart", rng) > 0;
rng.moveEnd("character", -1)) {
len++;
}
rng.setEndPoint("StartToStart", input.createTextRange());
for (var pos = { start: 0, end: len };
rng.compareEndPoints("EndToStart", rng) > 0;
rng.moveEnd("character", -1)) {
pos.start++;
pos.end++;
}
return pos;
}
}
return -1;
}
Use it in your code like this:
var cursorPosition = getCursorPos($('#myTextarea')[0])
Here's its complementary function:
function setCursorPos(input, start, end) {
if (arguments.length < 3) end = start;
if ("selectionStart" in input) {
setTimeout(function() {
input.selectionStart = start;
input.selectionEnd = end;
}, 1);
}
else if (input.createTextRange) {
var rng = input.createTextRange();
rng.moveStart("character", start);
rng.collapse();
rng.moveEnd("character", end - start);
rng.select();
}
}
For what it's worth:
I ran in to this issue when using Xamarin, even though I did have the Support packages installed, both the v4 and the v7 ones.

You could make it a bit cleaner.

Variable table is available only to the current session, for example, if you need to EXEC
another stored procedure within the current one you will have to pass the table as Table Valued Parameter
and of course this will affect the performance, with temporary tables you can do this with only passing the temporary table name
To test a Temporary table:
To test a Variable table:
something else I have experienced is: If your schema doesn't have GRANT
privilege to create tables then use variable tables.
In my case, changing the order of Maven Dependencies from Build Path configuration did not work for me. I changed its order from Run configuration.
Follow these steps:
• Go to Run -> Run Configurations...
• Click on the unit test's run configuration and click on the Classpath tab.
• check Use temporary JAR to specify classpath (to avoid classpath length limitations).
May be it is enough and your test works. You should try, so press Run button. If it did not work. Follow all previous steps again and without pressing Run button, go to the next step.
• In sub branches of User Entries move Maven Dependencies above your project or test class.
• Click Run button.
The problem is here:
answer = newList.sort()
sort
does not return the sorted list; rather, it sorts the list in place.
Use:
answer = sorted(newList)
You can use following code which generate pdf file in background as like on button click and then would popup in brwoser with SaveAs and cancel option.
Warning[] warnings;
string[] streamIds;
string mimeType = string.Empty;
string encoding = string.Empty;`enter code here`
string extension = string.Empty;
DataSet dsGrpSum, dsActPlan, dsProfitDetails,
dsProfitSum, dsSumHeader, dsDetailsHeader, dsBudCom = null;
enter code here
//This is optional if you have parameter then you can add parameters as much as you want
ReportParameter[] param = new ReportParameter[5];
param[0] = new ReportParameter("Report_Parameter_0", "1st Para", true);
param[1] = new ReportParameter("Report_Parameter_1", "2nd Para", true);
param[2] = new ReportParameter("Report_Parameter_2", "3rd Para", true);
param[3] = new ReportParameter("Report_Parameter_3", "4th Para", true);
param[4] = new ReportParameter("Report_Parameter_4", "5th Para");
DataSet dsData= "Fill this dataset with your data";
ReportDataSource rdsAct = new ReportDataSource("RptActDataSet_usp_GroupAccntDetails", dsActPlan.Tables[0]);
ReportViewer viewer = new ReportViewer();
viewer.LocalReport.Refresh();
viewer.LocalReport.ReportPath = "Reports/AcctPlan.rdlc"; //This is your rdlc name.
viewer.LocalReport.SetParameters(param);
viewer.LocalReport.DataSources.Add(rdsAct); // Add datasource here
byte[] bytes = viewer.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
// byte[] bytes = viewer.LocalReport.Render("Excel", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
// Now that you have all the bytes representing the PDF report, buffer it and send it to the client.

Response.Buffer = true;
Response.Clear();
Response.ContentType = mimeType;

Response.Flush(); // send it to the client to download
Response.End();
If you're running windows, fiddler is a great tool. It has a setting to simulate modem speed, and for someone who wants more control has a plugin to add latency to each request.
I prefer using a tool like this to putting latency code in my application as it is a much more realistic simulation, as well as not making me design or code the actual bits. The best code is code I don't have to write.
ADDED: This article at Pavel Donchev's blog on Software Technologies shows how to create custom simulated speeds: Limiting your Internet connection speed with Fiddler.
