The package is not fully compatible with dotnetcore 2.0 for now.
eg, for 'Microsoft.AspNet.WebApi.Client'
it maybe supported in version (5.2.4).
See Consume new Microsoft.AspNet.WebApi.Client.5.2.4 package for details.
You could try the standard Client package as Federico mentioned.
If that still not work, then as a workaround you can only create a Console App (.Net Framework)
instead of the .net core 2.0 console app.
Reference this thread: Microsoft.AspNet.WebApi.Client supported in .NET Core or not?

I tested it by requesting my website (apache) with all available chars on my german keyboard as URL parameter:
http://example.com/?^1234567890ß´qwertzuiopü+asdfghjklöä#<yxcvbnm,.-°!"§$%&/()=? `QWERTZUIOPÜ*ASDFGHJKLÖÄ\'>YXCVBNM;:_²³{[]}\|µ@€~
These were not encoded:
^0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ,.-!/()=?`*;:_{}[]\|~
Not encoded after urlencode()
:
0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.-_
Not encoded after rawurlencode()
:
0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.-_~
Note: Before PHP 5.3.0 rawurlencode()
encoded ~
because of RFC 1738. But this was replaced by RFC 3986 so its safe to use, now. But I do not understand why for example {}
are encoded through rawurlencode()
because they are not mentioned in RFC 3986.
An additional test I made was regarding auto-linking in mail texts. I tested Mozilla Thunderbird, aol.com, outlook.com, gmail.com, gmx.de and yahoo.de and they fully linked URLs containing these chars:
0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.-_~+#,%&=*;:@
Of course the ?
was linked, too, but only if it was used once.
Some people would now suggest to use only the rawurlencode()
chars, but did you ever hear that someone had problems to open these websites?
Asterisk
http://wayback.archive.org/web/*/http://google.com
Colon

Plus
https://plus.google.com/+google
At sign, Colon, Comma and Exclamation mark
https://www.google.com/maps/place/USA/@36.2218457,...
Because of that these chars should be usable unencoded without problems. Of course you should not use &;
because of encoding sequences like &
. The same reason is valid for %
as it used to encode chars in general. And =
as it assigns a value to a parameter name.
Finally I would say its ok to use these unencoded:
0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.-_~!+,*:@
But if you expect randomly generated URLs you should not use .!
, because those mark the end of a sentence and some mail apps will not auto-link the last char of the url. Example:
Visit http://example.com/foo=bar! !
XDocument
is from the LINQ to XML API, and XmlDocument
is the standard DOM-style API for XML. If you know DOM well, and don't want to learn LINQ to XML, go with XmlDocument
. If you're new to both, check out this page that compares the two, and pick which one you like the looks of better.
I've just started using LINQ to XML, and I love the way you create an XML document using functional construction. It's really nice. DOM is clunky in comparison.
if (strtotime($date)>strtotime(0)) { echo 'it is a date' }
Following up on Sergey's suggestion, you can define and reuse a whole Style (with various property setters, including Margin) instead of just a Thickness object:
<Style x:Key="MyStyle" TargetType="SomeItemType">
<Setter Property="Margin" Value="0,5,0,5" />
...
</Style>
...
<StackPanel>
<StackPanel.Resources>
<Style TargetType="SomeItemType" BasedOn="{StaticResource MyStyle}" />
</StackPanel.Resources>
...
</StackPanel>
Note that the trick here is the use of Style Inheritance for the implicit style, inheriting from the style in some outer (probably merged from external XAML file) resource dictionary.
Sidenote:
At first, I naively tried to use the implicit style to set the Style property of the control to that outer Style resource (say defined with the key "MyStyle"):
<StackPanel>
<StackPanel.Resources>
<Style TargetType="SomeItemType">
<Setter Property="Style" Value={StaticResource MyStyle}" />
</Style>
</StackPanel.Resources>
</StackPanel>
which caused Visual Studio 2010 to shut down immediately with CATASTROPHIC FAILURE error (HRESULT: 0x8000FFFF (E_UNEXPECTED)), as described at https://connect.microsoft.com/VisualStudio/feedback/details/753211/xaml-editor-window-fails-with-catastrophic-failure-when-a-style-tries-to-set-style-property#
$?
is used to find the return value of the last executed command.
Try the following in the shell:
ls somefile
echo $?
If somefile
exists (regardless whether it is a file or directory), you will get the return value thrown by the ls
command, which should be 0
(default "success" return value). If it doesn't exist, you should get a number other then 0. The exact number depends on the program.
For many programs you can find the numbers and their meaning in the corresponding man page. These will usually be described as "exit status" and may have their own section.
SQLite does not contain regular expression functionality by default.
It defines a REGEXP
operator, but this will fail with an error message unless you or your framework define a user function called regexp()
. How you do this will depend on your platform.
If you have a regexp()
function defined, you can match an arbitrary integer from a comma-separated list like so:
... WHERE your_column REGEXP "\b" || your_integer || "\b";
But really, it looks like you would find things a whole lot easier if you normalised your database structure by replacing those groups within a single column with a separate row for each number in the comma-separated list. Then you could not only use the =
operator instead of a regular expression, but also use more powerful relational tools like joins that SQL provides for you.
You've already done it correctly by using a DateTime
parameter with the value from the DateTime
, so it should already work. Forget about ToString()
- since that isn't used here.
If there is a difference, it is most likely to do with different precision between the two environments; maybe choose a rounding (seconds, maybe?) and use that. Also keep in mind UTC/local/unknown (the DB has no concept of the "kind" of date; .NET does).
I have a table and the date-times in it are in the format:
2011-07-01 15:17:33.357
Note that datetimes in the database aren't in any such format; that is just your query-client showing you white lies. It is stored as a number (and even that is an implementation detail), because humans have this odd tendency not to realise that the date you've shown is the same as 40723.6371916281
. Stupid humans. By treating it simply as a "datetime" throughout, you shouldn't get any problems.
There are two methods as of ES2015.
arguments
ObjectThis object is built into functions, and it refers to, appropriately, the arguments of a function. It is not technically an array, though, so typical array operations won't work on it. The suggested method is to use Array.from
or the spread operator to create an array from it.
I've seen other answers mention using slice
. Don't do that. It prevents optimizations (source: MDN).
Array.from(arguments)
[...arguments]
However, I would argue that arguments
is problematic because it hides what a function accepts as input. An arguments
function typically is written like this:
function mean(){
let args = [...arguments];
return args.reduce((a,b)=>a+b) / args.length;
}
Sometimes, the function header is written like the following to document the arguments in a C-like fashion:
function mean(/* ... */){ ... }
But that is rare.
As for why it is problematic, take C, for example. C is backwards compatible with an ancient pre-ANSI dialect of the language known as K&R C. K&R C allows function prototypes to have an empty arguments list.
int myFunction();
/* This function accepts unspecified parameters */
ANSI C provides a facility for varargs
(...
), and void
to specify an empty arguments-list.
int myFunction(void);
/* This function accepts no parameters */
Many people inadvertently declare functions with an unspecified
arguments list (int myfunction();
), when they expect the function to take zero arguments. This is technically a bug because the function will accept arguments. Any number of them.
A proper varargs
function in C takes the form:
int myFunction(int nargs, ...);
And JavaScript actually does have something similar to this.
I've already shown you the spread operator, actually.
...name
It's pretty versatile, and can also be used in a function's argument-list ("rest parameters") to specify varargs in a nicely documented fashion:
function mean(...args){
return args.reduce((a,b)=>a+b) / args.length;
}
Or as a lambda expression:
((...args)=>args.reduce((a,b)=>a+b) / args.length)(1,2,3,4,5); // 3
I much prefer the spread operator. It is clean and self-documenting.
You must declare the reportfile as variable for console.
Problem is all the Dokumentations you can find are not running so .. I was give 1 day of my live to find the right way ....
Example: for batch/console
cmd.exe /K set FFREPORT=file='C:\ffmpeg\proto\test.log':level=32 && C:\ffmpeg\bin\ffmpeg.exe -loglevel warning -report -i inputfile f outputfile
Exemple Javascript:
var reortlogfile = "cmd.exe /K set FFREPORT=file='C:\ffmpeg\proto\" + filename + ".log':level=32 && C:\ffmpeg\bin\ffmpeg.exe" .......;
You can change the dir and filename how ever you want.

Try this:
delete from your_table;
delete from sqlite_sequence where name='your_table';
SQLite keeps track of the largest ROWID that a table has ever held using the special
SQLITE_SEQUENCE
table. TheSQLITE_SEQUENCE
table is created and initialized automatically whenever a normal table that contains an AUTOINCREMENT column is created. The content of the SQLITE_SEQUENCE table can be modified using ordinary UPDATE, INSERT, and DELETE statements. But making modifications to this table will likely perturb the AUTOINCREMENT key generation algorithm. Make sure you know what you are doing before you undertake such changes.
Use TO_TIMESTAMP function
TO_TIMESTAMP(date_string,'YYYY-MM-DD HH24:MI:SS')
Although it is not an IntelliJ option, you could use a simple Bash command (if your operating system is Linux/Unix). Go to your source directory and type:
find . -type f -name '*.java' | xargs cat | wc -l
Here is an example of iterating over a pd.DataFrame
grouped by the column atable
. For this sample, "create" statements for an SQL database are generated within the for
loop:
import pandas as pd
df1 = pd.DataFrame({
'atable': ['Users', 'Users', 'Domains', 'Domains', 'Locks'],
'column': ['col_1', 'col_2', 'col_a', 'col_b', 'col'],
'column_type':['varchar', 'varchar', 'int', 'varchar', 'varchar'],
'is_null': ['No', 'No', 'Yes', 'No', 'Yes'],
})
df1_grouped = df1.groupby('atable')
# iterate over each group
for group_name, df_group in df1_grouped:
print('\nCREATE TABLE {}('.format(group_name))
for row_index, row in df_group.iterrows():
col = row['column']
column_type = row['column_type']
is_null = 'NOT NULL' if row['is_null'] == 'NO' else ''
print('\t{} {} {},'.format(col, column_type, is_null))
print(");")
Jacob Wright's Date.format()
library implements date formatting in the style of PHP's date()
function and supports the ISO-8601 week number:
new Date().format('W');
It may be a bit overkill for just a week number, but it does support PHP style formatting and is quite handy if you'll be doing a lot of this.
$array = array( 'one' =>'value', 'two' => 'value2' );
$allKeys = array_keys($array);
echo $allKeys[0];
Which will output:
one

That's a very complex question for a simple answer.
You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.
Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.
At the very top level I think quality REST API docs require at least the following:
Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.
Here's the correct answer, extracted from comments by Daniel Rikowski and pseidemann. I'm tired of having to weed through comments to find the right answer...

Open the file .git/refs/heads/<your_branch_name>
, and change the hash stored there to the one where you want to move the head of your branch. Just edit and save the file with any text editor. Just make sure that the branch to modify is not the current active one.
Disclaimer: Probably not an advisable way to do it, but gets the job done.
The only way is to use a formula or to format cells. The method i will use will be the following: Add another column next to these values. Then use the following formula:
=HOUR(A1)*60+MINUTE(A1)+SECOND(A1)/60
On the menu go to: "Run" --> "Run..." (or just press F5).
py -2 -i "$(FULL_CURRENT_PATH)"
py -3 -i "$(FULL_CURRENT_PATH)"
To understand the py
command better:
py -h

Follow up answer to help anyone doing this with the VS docker integration. I needed to change to port 8080 to run using the "flexible" environment in google appengine.
You'll need the following in your Dockerfile:
ENV ASPNETCORE_URLS=http://+:8080
EXPOSE 8080
and you'll need to modify the port in docker-compose.yml as well:
ports:
- "8080"
This might be too little too late but what helped me is the cool sounding 'nuclear' option. Basically using the command filter-branch

There's a jQuery plugin that allows you to manipulate SVG via Javascript:
http://plugins.jquery.com/project/svg
From its intro:
Supported natively in Firefox, Opera, and Safari and via the Adobe SVG viewer or Renesis player in IE, SVG lets you display graphics within your Web pages. Now you can easily drive the SVG canvas from your JavaScript code.
to remove disabled attribute use,
$("#elementID").removeAttr('disabled');
and to add disabled attribute use,
$("#elementID").prop("disabled", true);

Json.NET will do what you want (disclaimer: I'm the author of the package). It supports reading DataContract/DataMember attributes as well as its own to change the property names. Also there is the StringEnumConverter class for serializing enum values as the name rather than the number.
In case you happen to be using Spring framework along with java, there is an easy way around.
Import the following.
import org.springframework.util.Base64Utils;
Convert like this.
byte[] bytearr ={0,1,2,3,4}; String encodedText = Base64Utils.encodeToString(bytearr);
To decode you can use the decodeToString method of the Base64Utils class.
I think you want this:
foreach ($myarray as $key => $value) {
echo "$key = $value\n";
}
public AbstractType New
{
get
{
return (AbstractType) Activator.CreateInstance(GetType());
}
}
The escape code "
can also be used instead of "
.
Note: At the time I answered this question in 2010, there was no way to deserialize without some sort of type, this allowed you to deserialize without having go define the actual class and allowed an anonymous class to be used to do the deserialization.
You need to have some sort of type to deserialize to. You could do something along the lines of:
var product = new { Name = "", Price = 0 };
dynamic jsonResponse = JsonConvert.Deserialize(json, product.GetType());
My answer is based on a solution for .NET 4.0's build in JSON serializer. Link to deserialize to anonymous types is here:
The whereami library by Gregory Pakosz implements this for a variety of platforms, using the APIs mentioned in mark4o's post. This is most interesting if you "just" need a solution that works for a portable project and are not interested in the peculiarities of the various platforms.
At the time of writing, supported platforms are:
The library consists of whereami.c
and whereami.h
and is licensed under MIT and WTFPL2. Drop the files into your project, include the header and use it:
#include "whereami.h"
int main() {
int length = wai_getExecutablePath(NULL, 0, NULL);
char* path = (char*)malloc(length + 1);
wai_getExecutablePath(path, length, &dirname_length);
path[length] = '\0';
printf("My path: %s", path);
free(path);
return 0;
}
The best way to load an image is through the ImageIO
API
BufferedImage img = ImageIO.read(new File("/path/to/some/image"));
There are a number of ways you can render an image to the screen.
You could use a JLabel
. This is the simplest method if you don't want to modify the image in anyway...
JLabel background = new JLabel(new ImageIcon(img));
Then simply add it to your window as you see fit. If you need to add components to it, then you can simply set the label's layout manager to whatever you need and add your components.
If, however, you need something more sophisticated, need to change the image somehow or want to apply additional effects, you may need to use custom painting.
First cavert: Don't ever paint directly to a top level container (like JFrame
). Top level containers aren't double buffered, so you may end up with some flashing between repaints, other objects live on the window, so changing it's paint process is troublesome and can cause other issues and frames have borders which are rendered inside the viewable area of the window...
Instead, create a custom component, extending from something like JPanel
. Override it's paintComponent
method and render your output to it, for example...
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(img, 0, 0, this);
}
Take a look at Performing Custom Painting and 2D Graphics for more details
Try:
which( !is.na(p), arr.ind=TRUE)
Which I think is just as informative and probably more useful than the output you specified, But if you really wanted the list version, then this could be used:
> apply(p, 1, function(x) which(!is.na(x)) )
[[1]]
[1] 2 3
[[2]]
[1] 4 7
[[3]]
integer(0)
[[4]]
[1] 5
[[5]]
integer(0)
Or even with smushing together with paste:
lapply(apply(p, 1, function(x) which(!is.na(x)) ) , paste, collapse=", ")
The output from which
function the suggested method delivers the row and column of non-zero (TRUE) locations of logical tests:
> which( !is.na(p), arr.ind=TRUE)
row col
[1,] 1 2
[2,] 1 3
[3,] 2 4
[4,] 4 5
[5,] 2 7
Without the arr.ind
parameter set to non-default TRUE, you only get the "vector location" determined using the column major ordering the R has as its convention. R-matrices are just "folded vectors".
> which( !is.na(p) )
[1] 6 11 17 24 32

I test examples in js. Simplest solution - just add word u need inside / /:
var reg = /cat/;
reg.test('some cat here');//1 test
true // result
reg.test('acatb');//2 test
true // result
Now if u need this specific word with boundaries, not inside any other signs-letters. We use b marker:
var reg = /\bcat\b/
reg.test('acatb');//1 test
false // result
reg.test('have cat here');//2 test
true // result
We have also exec() method in js, whichone returns object-result. It helps f.g. to get info about place/index of our word.
var matchResult = /\bcat\b/.exec("good cat good");
console.log(matchResult.index); // 5
If we need get all matched words in string/sentence/text, we can use g modifier (global match):
"cat good cat good cat".match(/\bcat\b/g).length
// 3
Now the last one - i need not 1 specific word, but some of them. We use | sign, it means choice/or.
"bad dog bad".match(/\bcat|dog\b/g).length
// 1
Just my 2 cents regarding the divs option.
Famous/Infamous and SamsaraJS (and possibly others) use absolutely positioned non-nested divs (with non-trivial HTML/CSS content), combined with matrix2d/matrix3d for positioning and 2D/3D transformations, and achieve a stable 60FPS on moderate mobile hardware, so I'd argue against divs being a slow option.
There are plenty of screen recordings on Youtube and elsewhere, of high-performance 2D/3D stuff running in the browser with everything being an DOM element which you can Inspect Element on, at 60FPS (mixed with WebGL for certain effects, but not for the main part of the rendering).
Try:
function is_numeric(str){
try {
return isFinite(str)
}
catch(err) {
return false
}
}
You probably want to try something like this:
command = "cmd.exe /C dir C:\\"
I don't think you can pipe into cmd.exe
... If you are coming from a unix background, well, cmd.exe
has some ugly warts!
EDIT: According to Sven Marnach, you can pipe to cmd.exe
. I tried following in a python shell:
>>> import subprocess
>>> proc = subprocess.Popen('cmd.exe', stdin = subprocess.PIPE, stdout = subprocess.PIPE)
>>> stdout, stderr = proc.communicate('dir c:\\')
>>> stdout

I use the first (running the code against a test database). The only substantive issue I see you raising with this approach is the possibilty of schemas getting out of sync, which I deal with by keeping a version number in my database and making all schema changes via a script which applies the changes for each version increment.
I also make all changes (including to the database schema) against my test environment first, so it ends up being the other way around: After all tests pass, apply the schema updates to the production host. I also keep a separate pair of testing vs. application databases on my development system so that I can verify there that the db upgrade works properly before touching the real production box(es).
The cors-everywhere addon works for me until Firefox 68, after 68 I need to adjust 'privacy.file_unique_origin' -> false (by open 'about:config') to solve 'CORS request not HTTP' for new CORS same-origin rule introduced.
It is most likely that your configuration files are in src/main/resources, while they must be under src/test/resources to work properly under maven.

On Python = 3.5, use pathlib.Path.mkdir
:
from pathlib import Path
Path("/my/directory").mkdir(parents=True, exist_ok=True)
For older versions of Python, I see two answers with good qualities, each with a small flaw, so I will give my take on it:
Try os.path.exists
, and consider os.makedirs
for the creation.
import os
if not os.path.exists(directory):
os.makedirs(directory)
As noted in comments and elsewhere, there's a race condition – if the directory is created between the os.path.exists
and the os.makedirs
calls, the os.makedirs
will fail with an OSError
. Unfortunately, blanket-catching OSError
and continuing is not foolproof, as it will ignore a failure to create the directory due to other factors, such as insufficient permissions, full disk, etc.
One option would be to trap the OSError
and examine the embedded error code (see Is there a cross-platform way of getting information from Python’s OSError):
import os, errno
try:
os.makedirs(directory)
except OSError as e:

Alternatively, there could be a second os.path.exists
, but suppose another created the directory after the first check, then removed it before the second one – we could still be fooled.
Depending on the application, the danger of concurrent operations may be more or less than the danger posed by other factors such as file permissions. The developer would have to know more about the particular application being developed and its expected environment before choosing an implementation.
Modern versions of Python improve this code quite a bit, both by exposing FileExistsError
(in 3.3+)...
try:
os.makedirs("path/to/directory")
except FileExistsError:
# directory already exists
pass
...and by allowing a keyword argument to os.makedirs
called exist_ok
(in 3.2+).
os.makedirs("path/to/directory", exist_ok=True) # succeeds even if directory exists.
That's because you shouldn't do it (at least with an immutable list). If you really really need to append an element to the end of a data structure and this data structure really really needs to be a list and this list really really has to be immutable then do eiher this:
(4 :: List(1,2,3).reverse).reverse
or that:
List(1,2,3) ::: List(4)
Use the MemoryStream
class, calling Encoding.GetBytes
to turn your string into an array of bytes first.
Do you subsequently need a TextReader
on the stream? If so, you could supply a StringReader
directly, and bypass the MemoryStream
and Encoding
steps.
I had the same problem, and want to let you know that none of the above worked for me. What worked for me was:
Intent dialogIntent = new Intent(this, myActivity.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(dialogIntent);
and in one my subclasses, stored in a separate file I had to:
public static Service myService;
myService = this;
new SubService(myService);
Intent dialogIntent = new Intent(myService, myActivity.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
myService.startActivity(dialogIntent);
All the other answers gave me a nullpointerexception
.
This answer was not working for me so I went on to MSDN. There I found that now the code should look like this:
//var is of MessageBoxResult type
var result = MessageBox.Show(message, caption,
MessageBoxButtons.YesNo,
MessageBoxIcon.Question);
// If the no button was pressed ...
if (result == DialogResult.No)
{
...
}
Hope it helps
This is what worked for me:
Enter the command:
osql -S localhost\SQLEXPRESS -E
(or change localhost to whatever your PC is called).
At the prompt type the following commands:
CREATE LOGIN my_Login_here WITH PASSWORD = 'my_Password_here'
go
sp_addsrvrolemember 'my_Login_here', 'sysadmin'
go
quit
Stop the "SQL Server (SQLEXPRESS)" service.
Remove the "-m" from the Start parameters field (if still there).
Start the service.
In Management Studio, use the login and password you just created. This should give it admin permission.
Here's my 2 cents:
import sys
sys.path.append('/Users/John/Desktop')
import mapping #mapping.py is the name of my module file
shipit = mapping.Shipment() #Shipment is the name of the class I need to use in the mapping module
from mapping import Mapping
shipit = Shipment() #Now you don't have to use the .notation
A DAO allows for a simpler way to get data from storage, hiding the ugly queries.
Repository deals with data too and hides queries and all that but, a repository deals with business/domain objects.
A repository will use a DAO to get the data from the storage and uses that data to restore a business object.
For example, A DAO can contain some methods like that -
public abstract class MangoDAO{
abstract List<Mango>> getAllMangoes();
abstract Mango getMangoByID(long mangoID);
}
And a Repository can contain some method like that -
public abstract class MangoRepository{
MangoDao mangoDao = new MangDao;
Mango getExportQualityMango(){
for(Mango mango:mangoDao.getAllMangoes()){
/*Here some business logics are being applied.*/
if(mango.isSkinFresh()&&mangoIsLarge(){
mango.setDetails("It is an export quality mango");
return mango;
}
}
}
}
This tutorial helped me to get the main concept easily.
You have to convert the type of your return value of the method to the Generic type which you pass to the method during calling.
public static T values<T>()
{
Random random = new Random();
int number = random.Next(1, 4);
return (T)Convert.ChangeType(number, typeof(T));
}
You need pass a type that is type casteable for the value you return through that method.
If you would want to return a value which is not type casteable to the generic type you pass, you might have to alter the code or make sure you pass a type that is casteable for the return value of method. So, this approach is not reccomended.
Ok, call me paranoid but I suggest:
final android.view.ViewParent parent = view.getParent ();
if (parent instanceof android.view.ViewManager)
{
final android.view.ViewManager viewManager = (android.view.ViewManager) parent;
viewManager.removeView (view);
} // if
casting without instanceof
just seems wrong. And (thanks IntelliJ IDEA for telling me) removeView
is part of the ViewManager
interface. And one should not cast to a concrete class when a perfectly suitable interface is available.

The javaw command is identical to java, except that javaw has no associated console window. Use javaw when you do not want a command prompt window to be displayed. The javaw launcher displays a window with error information if it fails.
And javaws is for Java web start applications, applets, or something like that, I would suspect.
The best answer I can find, is in one of the comments here. Adding it to the answer so that someone won't miss the comment and should definitely try this out. It fixed the issue for me.
We need to map the solution folder to a drive using the "subst" command in command prompt- e.g., subst z:
And then open the solution from this drive (z in this case). This would shorten the path as much as possible and could solve the lengthy filename issue.

Personally I think Thread.Sleep
is a poor implementation. It locks the UI etc. I personally like timer implementations since it waits then fires.
Usage: DelayFactory.DelayAction(500, new Action(() => { this.RunAction(); }));
//Note Forms.Timer and Timer() have similar implementations.
public static void DelayAction(int millisecond, Action action)
{
var timer = new DispatcherTimer();
timer.Tick += delegate
{
action.Invoke();
timer.Stop();
};
timer.Interval = TimeSpan.FromMilliseconds(millisecond);
timer.Start();
}
The answer to this question has changed since it was asked a year ago. (This question is currently one of the top results for Googling "border-radius ie".)
IE9 will support border-radius
.
There is a platform preview available which supports border-radius
. You will need Windows Vista or Windows 7 to run the preview (and IE9 when it is released).

The viewBox
isn't the height of the container, it's the size of your drawing. Define your viewBox
to be 100 units in width, then define your rect
to be 10 units. After that, however large you scale the SVG, the rect
will be 10% the width of the image.
var val = yyy.First().Value;
return yyy.All(x=>x.Value == val) ? val : otherValue;
Cleanest way I can think of. You can make it a one-liner by inlining val, but First() would be evaluated n times, doubling execution time.
To incorporate the "empty set" behavior specified in the comments, you simply add one more line before the two above:
if(yyy == null || !yyy.Any()) return otherValue;
are you using jquery and prototype on the same page by any chance?
If so, use jquery noConflict mode, otherwise you are overwriting prototypes $ function.
noConflict mode is activated by doing the following:
<script src="jquery.js"></script>
<script>jQuery.noConflict();</script>
Note: by doing this, the dollar sign variable no longer represents the jQuery object. To keep from rewriting all your jQuery code, you can use this little trick to create a dollar sign scope for jQuery:
jQuery(function ($) {
// The dollar sign will equal jQuery in this scope
});
// Out here, the dollar sign still equals Prototype
For relative imports you have to:
b) provide anchor explicitly
importlib.import_module('.c', 'a.b')
Of course, you could also just do absolute import instead:
importlib.import_module('a.b.c')
After I have placed my dock to the right (see older answers), I still found the panels split vertically.
To split the panels horizontally - and even got more from your screen width - go to Settings (bottom right corner), and remove the check on 'Split panels vertically when docked to right'.
Now, you have all panels from left to right :p
Here is a solution which blocks all non numeric input from being entered into the text-field.
html
<input type="text" id="numbersOnly" />
javascript
var input = document.getElementById('numbersOnly');
input.onkeydown = function(e) {
var k = e.which;
/* numeric inputs can come from the keypad or the numeric row at the top */
if ( (k < 48 || k > 57) && (k < 96 || k > 105)) {
e.preventDefault();
return false;
}
};?
i faced an issue something like this...
Actually, in two ways you can process find
command output in copy
command
If find
command's output doesn't contain any space i.e if file name doesn't contain space in it then you can use below mentioned command:
Syntax: find <Path> <Conditions> | xargs cp -t <copy file path>
Example: find -mtime -1 -type f | xargs cp -t inner/
But most of the time our production data files might contain space in it. So most of time below mentioned command is safer:
Syntax: find <path> <condition> -exec cp '{}' <copy path> \;
Example find -mtime -1 -type f -exec cp '{}' inner/ \;
In the second example, last part i.e semi-colon is also considered as part of find
command, that should be escaped before press the enter button. Otherwise you will get an error something like this
find: missing argument to `-exec'
In your case, copy command syntax is wrong in order to copy find file into /home/shantanu/tosend
. The following command will work:
find /home/shantanu/processed/ -name '*2011*.xml' -exec cp {} /home/shantanu/tosend \;
Looks like you want split
I had this problem in InteliJ. I went to: Edit -> Configuration -> Deployment -> EditArtifact:
Then there where yellow problems, I just clicked on fix two times and it works. I hope this will help someone.
There are two ways to go about doing this.
Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.
handleClick: function() { alert(this.refs.myInput.value); },
And u can also use that select statement as left join query... Example :
... left join (select OrderNO,
PartCode,
Quantity from (select OrderNO,
PartCode,
Quantity,
row_number() over(partition by OrderNO order by DateEntered desc) as rn
from YourTable) as T where rn = 1 ) RESULT on ....
Hope this help someone that search for this :)

I had this problem, but only when I tried to rsync from a Linux (RH) server to a Solaris server. My fix was to make sure rsync had the same path on both boxes, and that the ownership of rsync was the same.
On the linux box, rsync path was /usr/bin, on Solaris box it was /usr/local/bin. So, on the Solaris box I did ln -s /usr/local/bin/rsync /usr/bin/rsync.
I still had the same problem, and noticed ownership differences. On linux it was root:root, on solaris it was bin:bin. Changing solaris to root:root fixed it.
This can dedupe the duplicated values in c1
:
select * from foo
minus
select f1.* from foo f1, foo f2
where f1.c1 = f2.c1 and f1.c2 > f2.c2
Use this to get the time in milliseconds (long)(NSTimeInterval)([[NSDate date] timeIntervalSince1970])
.
You are trying to access an XLS file. However, you are using XSSFWorkbook and XSSFSheet class objects. These classes are mainly used for XLSX files.
For XLS file: HSSFWorkbook
& HSSFSheet
For XLSX file: XSSFSheet
& XSSFSheet
So in place of XSSFWorkbook
use HSSFWorkbook
and in place of XSSFSheet
use HSSFSheet
.
So your code should look like this after the changes are made:
HSSFWorkbook workbook = new HSSFWorkbook(file);
HSSFSheet sheet = workbook.getSheetAt(0);
document.forms[0].action="http://..."
...assuming it is the first form on the page.
Give your inner div a width.
EXAMPLE
Change your CSS:
<style>
#outer { text-align: center; }
#inner { text-align: left; margin: 0 auto; }
.t { float: left; }
table { border: 1px solid black; }
#clearit { clear: left; }
</style>
To this:
<style>
#outer { text-align: center; }
#inner { text-align: left; margin: 0 auto; width:500px }
.t { float: left; }
table { border: 1px solid black; }
#clearit { clear: left; }
</style>

If a profiler is not applicable in your setup, you may try to identify the thread following steps in this post.
Basically, there are three steps:
top -H
and get PID of the thread with highest CPU.Try modifying the path in the windows registry (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment).
Caveat: Don't break the registry :)
Well this should change your format to text.

While you can call the parent method by the prototype of the parent, you will need to pass the current child instance for using call
, apply
, or bind
method. The bind
method will create a new function so I doesn't recommend that if you care for performance except it only called once.
As an alternative you can replace the child method and put the parent method on the instance while calling the original child method.
function proxy(context, parent){
var proto = parent.prototype;
var list = Object.getOwnPropertyNames(proto);
for(var i=0; i < list.length; i++){
var key = list[i];
// Create only when child have similar method name
if(context[key] !== proto[key]){
let currentMethod = context[key];
let parentMethod = proto[key];
context[key] = function(){
context.super = parentMethod;
return currentMethod.apply(context, arguments);
}
}
}
}
// ========= The usage would be like this ==========
class Parent {
first = "Home";
constructor(){
console.log('Parent created');
}
add(arg){
return this.first + ", Parent "+arg;
}
}
class Child extends Parent{
constructor(b){
super();
proxy(this, Parent);
console.log('Child created');
}
// Comment this to call method from parent only
add(arg){
return super.add(arg) + ", Child "+arg;
}
}
var family = new Child();
console.log(family.add('B'));

In the first place, you should note that PDF and HTML and different formats that hardly have anything in common. If TCPDF allows you to provide input data using HTML and CSS it's because it implements a simple parser for these two languages and tries to figure out how to translate that into PDF. So it's logical that TCPDF only supports a little subset of the HTML and CSS specification and, even in supported stuff, it's probably not as perfect as in first class web browsers.
Said that, the question is: what's supported and what's not? The documentation basically skips the issue and let's you enjoy the trial and error method.
Having a look at the source code, we can see there's a protected method called TCPDF::getHtmlDomArray()
that, among other things, parses CSS declarations. I can see stuff like font-family
, list-style-type
or text-indent
but there's no margin
or padding
as far as I can see and, definitively, there's no float
at all.
To sum up: with TCPDF, you can use CSS for some basic formatting. If you need to convert from HTML to PDF, it's the wrong tool. (If that's the case, may I suggest wkhtmltopdf?)
cv::Mat m;
m.create(10, 10, CV_32FC3);
float *array = (float *)malloc( 3*sizeof(float)*10*10 );
cv::MatConstIterator_<cv::Vec3f> it = m.begin<cv::Vec3f>();
for (unsigned i = 0; it != m.end<cv::Vec3f>(); it++ ) {
for ( unsigned j = 0; j < 3; j++ ) {
*(array + i ) = (*it)[j];
i++;
}
}
Now you have a float array. In case of 8 bit, simply change float
to uchar
, Vec3f
to Vec3b
and CV_32FC3
to CV_8UC3
.
If you know the settings in advance you can define it in a single statement:
var defaultsettings = {
ajaxsettings : { "ak1" : "v1", "ak2" : "v2", etc. },
uisettings : { "ui1" : "v1", "ui22" : "v2", etc }
};
If you don't know the values in advance you can just define the top level object and then add properties:
var defaultsettings = { };
defaultsettings["ajaxsettings"] = {};
defaultsettings["ajaxsettings"]["somekey"] = "some value";
Or half-way between the two, define the top level with nested empty objects as properties and then add properties to those nested objects:
var defaultsettings = {
ajaxsettings : { },
uisettings : { }
};
defaultsettings["ajaxsettings"]["somekey"] = "some value";
defaultsettings["uisettings"]["somekey"] = "some value";
You can nest as deep as you like using the above techniques, and anywhere that you have a string literal in the square brackets you can use a variable:
var keyname = "ajaxsettings";
var defaultsettings = {};
defaultsettings[keyname] = {};
defaultsettings[keyname]["some key"] = "some value";
Note that you can not use variables for key names in the { } literal syntax.
If you have apache running, put your file in server folder for html files and then call it from web-browser (Like http://localhost/myfile.php ).
Most probably, you didn't install any SQL Server Engine service. If no SQL Server engine is installed, no service will appear in the SQL Server Configuration Manager tool. Consider that the packages SQLManagementStudio_Architecture_Language.exe
and SQLEXPR_Architecture_Language.exe
, available in the Microsoft site contain, respectively only the Management Studio GUI Tools and the SQL Server engine.
If you want to have a full featured SQL Server installation, with the database engine and Management Studio, download the installer file of SQL Server with Advanced Services. Moreover, to have a sample database in order to perform some local tests, use the Adventure Works database.
Considering the package of SQL Server with Advanced Services, at the beginning at the installation you should see something like this (the screenshot below is about SQL Server 2008 Express, but the feature selection is very similar). The checkbox next to "Database Engine Services" must be checked. In the next steps, you will be able to configure the instance settings and other options.
Execute again the installation process and select the database engine services in the feature selection step. At the end of the installation, you should be able to see the SQL Server services in the SQL Server Configuration Manager.
I think this would be a more simpler way of outputting your results.
Sorry for using my own data should be easy to replace .
$query = "SELECT * FROM category ";
$result = mysqli_query($connection, $query);
while($row = mysqli_fetch_assoc($result))
{
$cat_id = $row['cat_id'];
$cat_title = $row['cat_title'];
echo $cat_id . " " . $cat_title ."<br>";
}
This would output :
As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).
On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.
You can check awesome material design components for AngularJS:

Partly, because Go doesn't have generics (so you would need one set-type for every type, or fall back on reflection, which is rather inefficient).
Partly, because if all you need is "add/remove individual elements to a set" and "relatively space-efficient", you can get a fair bit of that simply by using a map[yourtype]bool
(and set the value to true
for any element in the set) or, for more space efficiency, you can use an empty struct as the value and use _, present = the_setoid[key]
to check for presence.
In the accepted answer you get annoying spacing between the visible rows when the expandable row is hidden. You can get rid of that by adding this to css:
.collapse-row.collapsed + tr {
display: none;
}
'+' is adjacent sibling selector, so if you want your expandable row to be the next row, this selects the next tr following tr named collapse-row.
Here is updated fiddle: http://jsfiddle.net/Nb7wy/2372/
Header files can contain any valid C code, since they are injected into the compilation unit by the pre-processor prior to compilation.
If a header file contains a function, and is included by multiple .c
files, each .c
file will get a copy of that function and create a symbol for it. The linker will complain about the duplicate symbols.
It is technically possible to create static
functions in a header file for inclusion in multiple .c
files. Though this is generally not done because it breaks from the convention that code is found in .c
files and declarations are found in .h
files.
See the discussions in C/C++: Static function in header file, what does it mean? for more explanation.
In SVG (contrasted with HTML), you will want to use <image>

Can someone help me with the exact syntax?
It's a three-step process, and it involves modifying the openssl.cnf
file. You might be able to do it with only command line options, but I don't do it that way.
Find your openssl.cnf
file. It is likely located in /usr/lib/ssl/openssl.cnf
:
$ find /usr/lib -name openssl.cnf
/usr/lib/openssl.cnf
/usr/lib/openssh/openssl.cnf
/usr/lib/ssl/openssl.cnf
On my Debian system, /usr/lib/ssl/openssl.cnf
is used by the built-in openssl
program. On recent Debian systems it is located at /etc/ssl/openssl.cnf
You can determine which openssl.cnf
is being used by adding a spurious XXX
to the file and see if openssl
chokes.
First, modify the req
parameters. Add an alternate_names
section to openssl.cnf
with the names you want to use. There are no existing alternate_names
sections, so it does not matter where you add it.
[ alternate_names ]
DNS.1 = example.com
DNS.2 = www.example.com
DNS.3 = mail.example.com
DNS.4 = ftp.example.com
Next, add the following to the existing [ v3_ca ]
section. Search for the exact string [ v3_ca ]
:
subjectAltName = @alternate_names
You might change keyUsage
to the following under [ v3_ca ]
:
keyUsage = digitalSignature, keyEncipherment
digitalSignature
and keyEncipherment
are standard fare for a server certificate. Don't worry about nonRepudiation
. It's a useless bit thought up by computer science guys/gals who wanted to be lawyers. It means nothing in the legal world.
In the end, the IETF (RFC 5280), browsers and CAs run fast and loose, so it probably does not matter what key usage you provide.
Second, modify the signing parameters. Find this line under the CA_default
section:
# Extension copying option: use with caution.
# copy_extensions = copy
And change it to:
# Extension copying option: use with caution.
copy_extensions = copy
This ensures the SANs are copied into the certificate. The other ways to copy the DNS names are broken.
Third, generate your self-signed certificate:
$ openssl genrsa -out private.key 3072
$ openssl req -new -x509 -key private.key -sha256 -out certificate.pem -days 730
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
...
Finally, examine the certificate:
$ openssl x509 -in certificate.pem -text -noout

Copy this function in any module inside your vb.net project.
Public Function MakeTextBoxNumeric(kcode As Integer, shift As Boolean) As Boolean
If kcode >= 96 And kcode <= 105 Then
ElseIf kcode >= 48 And kcode <= 57
If shift = True Then Return False
ElseIf kcode = 8 Or kcode = 107 Then
ElseIf kcode = 187 Then
If shift = False Then Return False
Else
Return False
End If
Return True
End Function
Then use this function inside your textbox_keydown event like below:
Private Sub txtboxNumeric_KeyDown(sender As Object, e As KeyEventArgs) Handles txtboxNumeric.KeyDown
If MakeTextBoxNumeric(e.KeyCode, e.Shift) = False Then e.SuppressKeyPress = True

And yes. It works 100% :)
For who is searching for usable screen dimension without Status Bar and Action Bar (also thanks to Swapnil's answer):
DisplayMetrics dm = getResources().getDisplayMetrics();
float screen_w = dm.widthPixels;
float screen_h = dm.heightPixels;
int resId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resId > 0) {
screen_h -= getResources().getDimensionPixelSize(resId);
}
TypedValue typedValue = new TypedValue();
if(getTheme().resolveAttribute(android.R.attr.actionBarSize, typedValue, true)){
screen_h -= getResources().getDimensionPixelSize(typedValue.resourceId);
}
var result = projects.Where(p => filtedTags.All(t => p.Tags.Contains(t)));
Ok, I know this is a bit late, but since I stumbled upon this before finding the correct answer so might someone else.
From the django docs:
# This list contains a Blog object.
>>> Blog.objects.filter(name__startswith='Beatles')
[<Blog: Beatles Blog>]
# This list contains a dictionary.
>>> Blog.objects.filter(name__startswith='Beatles').values()
[{'id': 1, 'name': 'Beatles Blog', 'tagline': 'All the latest Beatles news.'}]
These properties in spring boot application.properties makes the acceptable file size unlimited -
# To prevent maximum upload size limit exception
spring.servlet.multipart.max-file-size=-1
spring.servlet.multipart.max-request-size=-1
To get rid of the first column of NAs, you can do it with negative indexing (which removes indices from the R data set). For example:
output = matrix(1:6, 2, 3) # gives you a 2 x 3 matrix filled with the numbers 1 to 6
# output =
# [,1] [,2] [,3]
# [1,] 1 3 5
# [2,] 2 4 6
output = output[,-1] # this removes column 1 for all rows
# output =
# [,1] [,2]
# [1,] 3 5
# [2,] 4 6
So you can just add output = output[,-1]
after the for loop in your original code.
I had tried below solution and it works for me, when concurrent request for insert statement occurs.
begin tran
if exists (select * from table with (updlock,serializable) where key = @key)
begin
update table set ...
where key = @key
end
else
begin
insert table (key, ...)
values (@key, ...)
end
commit tran
app:cardBackgroundColor="#488747"
use this in your card view and you can change a color of your card view
This line is your problem:
lstemail.Add("JOhn","Smith","Los Angeles");
There is no direct cast from 3 strings to your custom class. The compiler has no way of figuring out what you're trying to do with this line. You need to Add()
an instance of the class to lstemail
:
lstemail.Add(new EmailData { FirstName = "JOhn", LastName = "Smith", Location = "Los Angeles" });
git rebase -i @~9 # Show the last 9 commits in a text editor
Find the commit you want, change pick
to e
(edit
), and save and close the file. Git will rewind to that commit, allowing you to either:
git commit --amend
to make changes, orgit reset @~
to discard the last commit, but not the changes to the files (i.e. take you to the point you were at when you'd edited the files, but hadn't committed yet).The latter is useful for doing more complex stuff like splitting into multiple commits.
Then, run git rebase --continue
, and Git will replay the subsequent changes on top of your modified commit. You may be asked to fix some merge conflicts.
Note: @
is shorthand for HEAD
, and ~
is the commit before the specified commit.
Read more about rewriting history in the Git docs.
ProTip™: Don't be afraid to experiment with "dangerous" commands that rewrite history* — Git doesn't delete your commits for 90 days by default; you can find them in the reflog:
$ git reset @~3 # go back 3 commits
$ git reflog
c4f708b HEAD@{0}: reset: moving to @~3
2c52489 HEAD@{1}: commit: more changes
4a5246d HEAD@{2}: commit: make important changes
e8571e4 HEAD@{3}: commit: make some changes
... earlier commits ...
$ git reset 2c52489
... and you're back where you started
* Watch out for options like --hard
and --force
though — they can discard data.
* Also, don't rewrite history on any branches you're collaborating on.
On many systems, git rebase -i
will open up Vim by default. Vim doesn't work like most modern text editors, so take a look at how to rebase using Vim. If you'd rather use a different editor, change it with git config --global core.editor your-favorite-text-editor

All OS comes with a default version of python and it resides in /usr/bin. All scripts that come with the OS (e.g. yum) point this version of python residing in /usr/bin. When you want to install a new version of python you do not want to break the existing scripts which may not work with new version of python.
The right way of doing this is to install the python as an alternate version.
e.g.
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
tar xf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure --prefix=/usr/local/
make && make altinstall
Now by doing this the existing scripts like yum still work with /usr/bin/python. and your default python version would be the one installed in /usr/local/bin. i.e. when you type python you would get 2.7.3
This happens because. $PATH variable has /usr/local/bin before usr/bin.
/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
If python2.7 still does not take effect as the default python version you would need to do
export PATH="/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin"
I've found a solution for width: "100%", height: "auto" if you know the aspectRatio (width / height) of the image.
Here's the code:
import { Image, StyleSheet, View } from 'react-native';
const image = () => (
<View style={styles.imgContainer}>
<Image style={styles.image} source={require('assets/images/image.png')} />
</View>
);
const style = StyleSheet.create({
imgContainer: {
flexDirection: 'row'
},
image: {
resizeMode: 'contain',
flex: 1,
aspectRatio: 1 // Your aspect ratio
}
});
This is the most simplest way I could get it to work without using onLayout
or Dimension
calculations. You can even wrap it in a simple reusable component if needed. Give it a shot if anyone is looking for a simple implementation.
Assuming the original date is in cell A1:

Can i just point out what you are all trying to set and int where its expecting a drawable.
should you not be doing the following?
imageview.setImageDrawable(this.getResources().getDrawable(R.drawable.icon_image));
imageview.setImageDrawable(getApplicationContext().getResources().getDrawable(R.drawable.icon_profile_image));
A short traverse could be given too using the sub-expression operator $( ), which returns the result of one or more statements.
$hash = @{ a = 1; b = 2; c = 3}
forEach($y in $hash.Keys){
Write-Host "$y -> $($hash[$y])"
}
Result:
a -> 1
b -> 2
c -> 3
As others point out, the user name is usually anonymous, and the password is usually your e-mail address, but this is not universally true, and has been found not to work for certain anonymous FTP sites. For example, at least some cPanel sites seem to deviate from the norm, and if given the traditional user name without domain, one of various errors may result:
If the server uses Pure-FTP as the FTP server:
421 Can't change directory to /var/ftp/ error message.
If the server uses ProFTP as the FTP server:
530 Login Authentication Failed error message.
When one of the aforementioned errors occurs when attempting anonymous access, try including a domain with the username. For example, where example.com is the domain used in your e-mail address:
User name: [email protected]
In the specific case of a cPanel site, the password value is unimportant, and may be left blank, but there is no harm in providing a "traditional" anonymous password formatted as an e-mail address.
For reference, this answer is based on content found on a documentation.cpanel.net Anonymous FTP page. At the time of this writing, it stated:
When users log in to FTP anonymously, they must format usernames as
[email protected]
, whereexample.com
represents the user's domain name. This requirement directs your server to the correctpublic_ftp
directory.
For all who use the TIMESTAMP column as a solution i want to second the following limitation from the manual:
http://dev.mysql.com/doc/refman/5.0/en/datetime.html
"The TIMESTAMP data type has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC. It has varying properties, depending on the MySQL version and the SQL mode the server is running in. These properties are described later in this section. "
So this will obviously break your software in about 28 years.
I believe the only solution on the database side is to use triggers like mentioned in other answers.
I had to add width: 100%; to display table to fix some strange bahavior in IE and FF, when i used this example. IE and FF had some problems displaying the col-md-* tags at the right width
.display-table {
display: table;
table-layout: fixed;
width: 100%;
}
.display-cell {
display: table-cell;
vertical-align: middle;
float: none;
}
Quite late to this party, today I had the same problem.
The right answer on macOs I think is use jenv
brew install jenv openjdk@11
jenv add /usr/local/opt/openjdk@11
And then add into Intellij IDEA as new SDK the following path:
~/.jenv/versions/11/libexec/openjdk.jdk/Contents/Home/
<div class="jumbotron">
<div class="container">
<div class="row">
<div>
<h2 class="col-md-4 offset-md-4">Browse.</h2>
<h2 class="col-md-4 offset-md-4">create.</h2>
<h2 class="col-md-4 offset-md-4">share.</h2>
</div>
</div>
</div>
</div>
You can try this.
When you write .class
after a class name, it references the class literal -
java.lang.Class
object that represents information about given class.
For example, if your class is Print
, then Print.class
is an object that represents the class Print
on runtime. It is the same object that is returned by the getClass()
method of any (direct) instance of Print
.
Print myPrint = new Print();
System.out.println(Print.class.getName());
System.out.println(myPrint.getClass().getName());

You must also implement View.OnClickListener and in On Click method can use intent
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.setData(Uri.parse("https://youraddress.com"));
startActivity(intent);
I tested this solution works fine.
Um, why not just:
>>>> import os
>>>> os.path.join(dir_name, base_filename + "." + format)
'/home/me/dev/my_reports/daily_report.pdf'
Syntax looks like:
$ split [OPTION] [INPUT [PREFIX]]
where prefix is PREFIXaa, PREFIXab, ...
Just use proper one and youre done or just use mv for renameing.
I think
$ mv * *.txt
should work but test it first on smaller scale.
:)
To anyone interested, here's a class I created using inazaruk's code that creates everything needed (I called it UIUpdater because I use it to periodically update the UI, but you can call it anything you like):
import android.os.Handler;
/**
* A class used to perform periodical updates,
* specified inside a runnable object. An update interval
* may be specified (otherwise, the class will perform the
* update every 2 seconds).
*
* @author Carlos Simões
*/
public class UIUpdater {
// Create a Handler that uses the Main Looper to run in
private Handler mHandler = new Handler(Looper.getMainLooper());
private Runnable mStatusChecker;
private int UPDATE_INTERVAL = 2000;
/**
* Creates an UIUpdater object, that can be used to
* perform UIUpdates on a specified time interval.
*
* @param uiUpdater A runnable containing the update routine.
*/
public UIUpdater(final Runnable uiUpdater) {
mStatusChecker = new Runnable() {
@Override
public void run() {
// Run the passed runnable
uiUpdater.run();
// Re-run it after the update interval
mHandler.postDelayed(this, UPDATE_INTERVAL);
}
};
}
/**
* The same as the default constructor, but specifying the
* intended update interval.
*
* @param uiUpdater A runnable containing the update routine.
* @param interval The interval over which the routine
* should run (milliseconds).
*/
public UIUpdater(Runnable uiUpdater, int interval){
UPDATE_INTERVAL = interval;
this(uiUpdater);
}
/**
* Starts the periodical update routine (mStatusChecker
* adds the callback to the handler).
*/
public synchronized void startUpdates(){
mStatusChecker.run();
}
/**
* Stops the periodical update routine from running,
* by removing the callback.
*/
public synchronized void stopUpdates(){
mHandler.removeCallbacks(mStatusChecker);
}
}
You can then create a UIUpdater object inside your class and use it like so:
...
mUIUpdater = new UIUpdater(new Runnable() {
@Override
public void run() {
// do stuff ...
}
});
// Start updates
mUIUpdater.startUpdates();
// Stop updates
mUIUpdater.stopUpdates();
...
If you want to use this as an activity updater, put the start call inside the onResume() method and the stop call inside the onPause(), so the updates start and stop according to the activity visibility.

To create user in MySQL/MariaDB 5.7.6 and higher, use CREATE USER
syntax:
CREATE USER 'new_user'@'localhost' IDENTIFIED BY 'new_password';
then to grant all access to the database (e.g. my_db
), use GRANT
Syntax, e.g.
GRANT ALL ON my_db.* TO 'new_user'@'localhost';
Where ALL
(priv_type) can be replaced with specific privilege such as SELECT
, INSERT
, UPDATE
, ALTER
, etc.
Then to reload newly assigned permissions run:
FLUSH PRIVILEGES;
To run above commands, you need to run mysql
command and type them into prompt, then logout by quit
command or Ctrl-D.
To run from shell, use -e
parameter (replace SELECT 1
with one of above commands):
$ mysql -e "SELECT 1"
or print statement from the standard input:
$ echo "FOO STATEMENT" | mysql
If you've got Access denied with above, specify -u
(for user) and -p
(for password) parameters, or for long-term access set your credentials in ~/.my.cnf
, e.g.
[client]
user=root
password=root
For people not familiar with MySQL syntax, here are handy shell functions which are easy to remember and use (to use them, you need to load the shell functions included further down).
Here is example:
$ mysql-create-user admin mypass
| CREATE USER 'admin'@'localhost' IDENTIFIED BY 'mypass'
$ mysql-create-db foo
| CREATE DATABASE IF NOT EXISTS foo
$ mysql-grant-db admin foo
| GRANT ALL ON foo.* TO 'admin'@'localhost'
| FLUSH PRIVILEGES
$ mysql-show-grants admin
| SHOW GRANTS FOR 'admin'@'localhost'
| Grants for admin@localhost
| GRANT USAGE ON *.* TO 'admin'@'localhost' IDENTIFIED BY PASSWORD '*6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4' |
| GRANT ALL PRIVILEGES ON `foo`.* TO 'admin'@'localhost'
$ mysql-drop-user admin
| DROP USER 'admin'@'localhost'
$ mysql-drop-db foo
| DROP DATABASE IF EXISTS foo
To use above commands, you need to copy&paste the following functions into your rc file (e.g. .bash_profile
) and reload your shell or source the file. In this case just type source .bash_profile
:
# Create user in MySQL/MariaDB.
mysql-create-user() {
[ -z "$2" ] && { echo "Usage: mysql-create-user (user) (password)"; return; }
mysql -ve "CREATE USER '$1'@'localhost' IDENTIFIED BY '$2'"
}
# Delete user from MySQL/MariaDB
mysql-drop-user() {
[ -z "$1" ] && { echo "Usage: mysql-drop-user (user)"; return; }
mysql -ve "DROP USER '$1'@'localhost';"
}
# Create new database in MySQL/MariaDB.
mysql-create-db() {
[ -z "$1" ] && { echo "Usage: mysql-create-db (db_name)"; return; }
mysql -ve "CREATE DATABASE IF NOT EXISTS $1"
}
# Drop database in MySQL/MariaDB.
mysql-drop-db() {
[ -z "$1" ] && { echo "Usage: mysql-drop-db (db_name)"; return; }
mysql -ve "DROP DATABASE IF EXISTS $1"
}
# Grant all permissions for user for given database.
mysql-grant-db() {
[ -z "$2" ] && { echo "Usage: mysql-grand-db (user) (database)"; return; }
mysql -ve "GRANT ALL ON $2.* TO '$1'@'localhost'"
mysql -ve "FLUSH PRIVILEGES"
}
# Show current user permissions.
mysql-show-grants() {
[ -z "$1" ] && { echo "Usage: mysql-show-grants (user)"; return; }
mysql -ve "SHOW GRANTS FOR '$1'@'localhost'"
}
Note: If you prefer to not leave trace (such as passwords) in your Bash history, check: How to prevent commands to show up in bash history?
You need to add a vertical-align
property to your two child div's.
If .small
is always shorter, you need only apply the property to .small
.
However, if either could be tallest then you should apply the property to both .small
and .big
.
.container{
border: 1px black solid;
width: 320px;
height: 120px;
}
.small{
display: inline-block;
width: 40%;
height: 30%;
border: 1px black solid;
background: aliceblue;
vertical-align: top;
}
.big {
display: inline-block;
border: 1px black solid;
width: 40%;
height: 50%;
background: beige;
vertical-align: top;
}
Vertical align affects inline or table-cell box's, and there are a large nubmer of different values for this property. Please see https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align for more details.
At its core, Git is a set of command line utility programs that are designed to execute on a Unix style command-line environment. Modern operating systems like Linux and macOS both include built-in Unix command line terminals. This makes Linux and macOS complementary operating systems when working with Git. Microsoft Windows instead uses Windows command prompt, a non-Unix terminal environment.
What is Git Bash?
Git Bash is an application for Microsoft Windows environments which provides an emulation layer for a Git command line experience. Bash is an acronym for Bourne Again Shell. A shell is a terminal application used to interface with an operating system through written commands. Bash is a popular default shell on Linux and macOS. Git Bash is a package that installs Bash, some common bash utilities, and Git on a Windows operating system.

(5,6,7,8),
(9,0,1,2))
Using tuples instead of lists makes it marginally harder to change the data structure in unwanted ways.
If you are going to do extensive use of those, you are best off wrapping a true number array in a class, so you can define methods and properties on them. (Or, you could NumPy, SciPy, ... if you are going to do your processing with those libraries.)
The Javadocs from Sun for each collection class will generally tell you exactly what you want. HashMap, for example:
This implementation provides constant-time performance for the basic operations (get and put), assuming the hash function disperses the elements properly among the buckets. Iteration over collection views requires time proportional to the "capacity" of the HashMap instance (the number of buckets) plus its size (the number of key-value mappings).
This implementation provides guaranteed log(n) time cost for the containsKey, get, put and remove operations.
This implementation provides guaranteed log(n) time cost for the basic operations (add, remove and contains).

As others have said, # coding:
specifies the encoding the source file is saved in. Here are some examples to illustrate this:
A file saved on disk as cp437 (my console encoding), but no encoding declared
b = 'über'
u = u'über'
print b,repr(b)
print u,repr(u)
Output:
File "C:\ex.py", line 1
SyntaxError: Non-ASCII character '\x81' in file C:\ex.py on line 1, but no
encoding declared; see http://www.python.org/peps/pep-0263.html for details
Output of file with # coding: cp437
added:
über '\x81ber'
über u'\xfcber'
At first, Python didn't know the encoding and complained about the non-ASCII character. Once it knew the encoding, the byte string got the bytes that were actually on disk. For the Unicode string, Python read \x81, knew that in cp437 that was a ü, and decoded it into the Unicode codepoint for ü which is U+00FC. When the byte string was printed, Python sent the hex value 81
to the console directly. When the Unicode string was printed, Python correctly detected my console encoding as cp437 and translated Unicode ü to the cp437 value for ü.
Here's what happens with a file declared and saved in UTF-8:
++ber '\xc3\xbcber'
über u'\xfcber'
In UTF-8, ü is encoded as the hex bytes C3 BC
, so the byte string contains those bytes, but the Unicode string is identical to the first example. Python read the two bytes and decoded it correctly. Python printed the byte string incorrectly, because it sent the two UTF-8 bytes representing ü directly to my cp437 console.
Here the file is declared cp437, but saved in UTF-8:
++ber '\xc3\xbcber'
++ber u'\u251c\u255dber'
The byte string still got the bytes on disk (UTF-8 hex bytes C3 BC
), but interpreted them as two cp437 characters instead of a single UTF-8-encoded character. Those two characters where translated to Unicode code points, and everything prints incorrectly.
This is helpful for people struggling to find better site to generate icons and splashscreen
If the child entity is used readonly, then it's possible to simply lie and set optional=false
.
Then ensure that every use of that mapped entity is preloaded via queries.
public class App {

private Attributes additional;
and
String sql = " ... FROM App a LEFT JOIN FETCH a.additional aa ...";
... maybe even persisting would work...
In Express 4.x
I used the following to load ejs
:
var path = require('path');
// Set the default templating engine to ejs
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
// The views/index.ejs exists in the app directory
app.get('/hello', function (req, res) {
res.render('index', {title: 'title'});
});
Then you just need two files to make it work - views/index.ejs
:
<%- include partials/navigation.ejs %>
And the views/partials/navigation.ejs
:
<ul><li class="active">...</li>...</ul>
You can also tell Express to use ejs
for html templates:
var path = require('path');
var EJS = require('ejs');
app.engine('html', EJS.renderFile);
// Set the default templating engine to ejs
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
// The views/index.html exists in the app directory
app.get('/hello', function (req, res) {
res.render('index.html', {title: 'title'});
});
Finally you can also use the ejs
layout module:
var EJSLayout = require('express-ejs-layouts');
app.use(EJSLayout);
This will use the views/layout.ejs
as your layout.
I think this is the simple answer you are looking for. It's from Shawn Wildermuth's blog:
// Add MVC services to the services container.
services.AddMvc()
.AddJsonOptions(opts =>
{
opts.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
});
Interactive Debugging of Scripts (and doctest strings)
I don't think this is as widely known as it could be, but add this line to any python script:
import pdb; pdb.set_trace()
will cause the PDB debugger to pop up with the run cursor at that point in the code. What's even less known, I think, is that you can use that same line in a doctest:
"""
>>> 1 in (1,2,3)
Becomes
>>> import pdb; pdb.set_trace(); 1 in (1,2,3)
"""
You can then use the debugger to checkout the doctest environment. You can't really step through a doctest because the lines are each run autonomously, but it's a great tool for debugging the doctest globs and environment.
You should be able to create a custom exception class that extends the Exception
class, for example:
class WordContainsException extends Exception
{
// Parameterless Constructor
public WordContainsException() {}
// Constructor that accepts a message
public WordContainsException(String message)
{
super(message);
}
}
Usage:
try
{
if(word.contains(" "))
{
throw new WordContainsException();
}
}
catch(WordContainsException ex)
{
// Process message however you would like
}
To change working directory in GitMSYS's Git Bash you can just use cd
cd /path/do/directory
Note that:
/
) instead of backslash.C:\stuff
" should be represented with "/c/stuff
".\
)Also, you can right click in Windows Explorer on a directory and "Git Bash here".
Felix Kling did a great comparison on those two, for anyone wondering how to do an export default alongside named exports with module.exports in nodejs
module.exports = new DAO()
module.exports.initDAO = initDAO // append other functions as named export
// now you have
let DAO = require('_/helpers/DAO');
// DAO by default is exported class or function
DAO.initDAO()
If you use sufficiently big list not in b
clause will do a linear search for each of the item in a
. Why not use set? Set takes iterable as parameter to create a new set object.
>>> a = ["a", "b", "c", "d", "e"]
>>> b = ["c", "d", "f", "g"]
>>> set(a).intersection(set(b))
{'c', 'd'}
In addition to grants, you can try creating synonyms. It will avoid the need for specifying the table owner schema every time.
From the connecting schema:
CREATE SYNONYM pi_int FOR pct.pi_int;
Then you can query pi_int
as:
SELECT * FROM pi_int;
ASP.NET 2 and SQL Server reporting services 2005 have a limit of 2028. I found this out the hard way, where my dynamic URL generator would not pass over some parameters to a report beyond that point. This was under Internet Explorer 8.
I favor field accessors. The code is much cleaner. All the annotations can be placed in one section of a class and the code is much easier to read.
I found another problem with property accessors: if you have getXYZ methods on your class that are NOT annotated as being associated with persistent properties, hibernate generates sql to attempt to get those properties, resulting in some very confusing error messages. Two hours wasted. I did not write this code; I have always used field accessors in the past and have never run into this issue.
Hibernate versions used in this app:
<!-- hibernate -->
<hibernate-core.version>3.3.2.GA</hibernate-core.version>
<hibernate-annotations.version>3.4.0.GA</hibernate-annotations.version>
<hibernate-commons-annotations.version>3.1.0.GA</hibernate-commons-annotations.version>
<hibernate-entitymanager.version>3.4.0.GA</hibernate-entitymanager.version>
An expression like
dosomething1 && dosomething2 && dosomething3
will stop processing when one of the commands returns with a non-zero value. For example, the following command will never print "done":
cat nosuchfile && echo "done"
echo $?
1
I would have thought that something like this would be much better, since you're adding a variable, so why not restrict access and make it cleaner? Your getter/setters should do what they say on the tin.

Bringing this back to the question, do you ever bother looking at where the getter/setter code is when reading it? If they all do getting and setting then you don't need to worry about what the function 'does' when reading the code. There are a few other reasons to think about too:
Always think whether your class is really a different thing or not, and that should help decide whether you need anything more.
If you want to control the formatting of the unique identifier you can create your own <FieldType>
in SharePoint. MSDN also has a visual How-To. This basically means that you're creating a custom column.
WSS defines the Counter field type (which is what the ID column above is using). I've never had the need to re-use this or extend it, but it should be possible.
A solution might exist without creating a custom <FieldType>
. For example: if you wanted unique IDs like CUST1, CUST2, ... it might be possible to create a Calculated column and use the value of the ID column in you formula (="CUST" & [ID]
). I haven't tried this, but this should work :)
The solutions of Fabricio works just fine.
A very common usecase of calc is add 100% width and adding some margin around the element.
One can do so with:
@someMarginVariable: 15px;
margin: @someMarginVariable;
width: calc(~"100% - "@someMarginVariable*2);
width: -moz-calc(~"100% - "@someMarginVariable*2);
width: -webkit-calc(~"100% - "@someMarginVariable*2);
width: -o-calc(~"100% - "@someMarginVariable*2);
Or can use a mixin like:
.fullWidthMinusMarginPaddingMixin(@marginSize,@paddingSize) {
@minusValue: (@marginSize+@paddingSize)*2;
padding: @paddingSize;
margin: @marginSize;
width: calc(~"100% - "@minusValue);
width: -moz-calc(~"100% - "@minusValue);
width: -webkit-calc(~"100% - "@minusValue);
width: -o-calc(~"100% - "@minusValue);
}

Adding to slebetman's answer for more clarity on what happens while executing the code.
The internal thread pool in nodeJs just has 4 threads by default. and its not like the whole request is attached to a new thread from the thread pool the whole execution of request happens just like any normal request (without any blocking task) , just that whenever a request has any long running or a heavy operation like db call ,a file operation or a http request the task is queued to the internal thread pool which is provided by libuv. And as nodeJs provides 4 threads in internal thread pool by default every 5th or next concurrent request waits until a thread is free and once these operations are over the callback is pushed to the callback queue. and is picked up by event loop and sends back the response.
Now here comes another information that its not once single callback queue, there are many queues.
Whenever a request comes the code gets executing in this order of callbacks queued.
It is not like when there is a blocking request it is attached to a new thread. There are only 4 threads by default. So there is another queueing happening there.
Whenever in a code a blocking process like file read occurs , then calls a function which utilises thread from thread pool and then once the operation is done , the callback is passed to the respective queue and then executed in the order.
Everything gets queued based on the the type of callback and processed in the order mentioned above.
For ASP.NET 1.1, this is still due to someone posting more than 1000 form fields, but the setting must be changed in the registry rather than a config file. It should be added as a DWORD named MaxHttpCollectionKeys in the registry under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ASP.NET\1.1.4322.0
for 32-bit editions of Windows, and
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ASP.NET\1.1.4322.0
for 64-bit editions of Windows.
you can also use gcc -v
command that works like gcc --version
and if you would like to now where gcc
is you can use whereis gcc

For NodeJS v12 and above, --experimental-json-modules
would do the trick, without any help from babel.

But it is imported in commonjs form, so import { a, b } from 'c.json'
is not yet supported.
But you can do:
import c from 'c.json';

The difference between them is that they use different pins. Seriously, that's it. The reason they both exist is that RTS/CTS wasn't supposed to ever be a flow control mechanism, originally; it was for half-duplex modems to coordinate who was sending and who was receiving. RTS and CTS got misused for flow control so often that it became standard.
An HTTP server is conceptually simple:
It gets more difficult depending on how much of HTTP you want to support - POST is a little more complicated, scripts, handling multiple requests, etc.
But the base is very simple.

How about this:
EXECUTE xp_regread @rootkey='HKEY_LOCAL_MACHINE',

@value_name='MSSQLSERVER'
This will get the instance name as well. null
means default instance:

If g++
still gives error Try using:
g++ file.c -lstdc++
Look at this post: What is __gxx_personality_v0 for?
Make sure -lstdc++
is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.
May be this time stamp fit you better Code
Function LastInputTimeStamp() As Date
LastInputTimeStamp = Now()
End Function
and each time you input data in defined cell (in my example below it is cell C36) you'll get a new constant time stamp. As an example in Excel file may use this
=IF(C36>0,LastInputTimeStamp(),"")
No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:variable name="mapping">
<item key="1" v1="A" v2="B" />
<item key="2" v1="X" v2="Y" />
</xsl:variable>
<xsl:variable name="mappingNode"
select="document('')//xsl:variable[@name = 'mapping']" />
<xsl:template match="....">
<xsl:variable name="testVariable" select="'1'" />
<xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />
<xsl:variable name="variable1" select="$values/@v1" />
<xsl:variable name="variable2" select="$values/@v2" />
</xsl:template>
</xsl:stylesheet>
In fact, once you've got the values
variable, you may not even need separate variable1
and variable2
variables. You could just use $values/@v1
and $values/@v2
instead.
You can disable validators conditionally by removing errors from ModelState:
ModelState["DependentProperty"].Errors.Clear();
Just move the extra condition into the JOIN ON criteria, this way the existence of b is not required to return a result
SELECT a.* FROM a
LEFT JOIN b ON a.group_id=b.group_id AND b.user_id!=$_SESSION{['user_id']}
WHERE a.keyword LIKE '%".$keyword."%'
GROUP BY group_id
Python 3.6 now supports shorthand literal string interpolation with PEP 498. For your use case, the new syntax is simply:
f"({self.goals} goals, ${self.penalties})"
This is similar to the previous .format
standard, but lets one easily do things like:
>>> width = 10
>>> precision = 4
>>> value = decimal.Decimal('12.34567')
>>> f'result: {value:{width}.{precision}}'
'result: 12.35'
Recoll is a fantastic full-text GUI search application for Unix/Linux that supports dozens of different formats, including PDF. It can even pass the exact page number and search term of a query to the document viewer and thus allows you to jump to the result right from its GUI.
Recoll also comes with a viable command-line interface and a web-browser interface.

I combined several approaches here. I like the idea of the preprocessor and the indexed list.
There's no extra dynamic allocation, and because of the inlining the compiler might be able to optimize the lookup.
typedef NS_ENUM(NSUInteger, FormatType) { FormatTypeJSON = 0, FormatTypeXML, FormatTypeAtom, FormatTypeRSS, FormatTypeCount };
NS_INLINE NSString *FormatTypeToString(FormatType t) {
if (t >= FormatTypeCount)
return nil;
#define FormatTypeMapping(value) [value] = @#value
NSString *table[FormatTypeCount] = {FormatTypeMapping(FormatTypeJSON),
FormatTypeMapping(FormatTypeXML),
FormatTypeMapping(FormatTypeAtom),
FormatTypeMapping(FormatTypeRSS)};
#undef FormatTypeMapping
return table[t];
}

Brian Clark's answer above worked for me, but I'm posting here for those who may have to follow a slightly different sequence as I did.
When I ran Control Panel > Administrative Tools > Right Click Task Scheduler - 'Run as Administrator', I found the Actions pane to already contain the following action:
Disable All Tasks History
So my machine already had History enabled. But my machine needed to disable history first, then go back and 'Enable All Tasks History'. After that, my History showed up and I received no more errors. I'm assuming that action performed some type of initialization or setup that was never done properly from all the way back to OS installation.
I will also add that I had to exit Task Scheduler and reenter it before I could toggle the History Enable/Disable setting back and forth.
Yes, take a look at this thread which talks about the differences between platforms.

is the same across all platforms, being equal to the right mouse button. BUTTON2 is simply ignored if the middle button does not exist.
I was getting this same warning everytime I was doing 'maven clean'. I found the solution :
Step - 1 Right click on your project in Eclipse
Step - 2 Click Properties
Step - 3 Select Maven in the left hand side list.
Step - 4 You will notice "pom.xml" in the Active Maven Profiles text box on the right hand side. Clear it and click Apply.
Below is the screen shot :
Hope this helps. :)
Since you're going to be dealing with data of a variable length (names, email addresses), then you'd be wanting to use VARCHAR. The amount of space taken up by a VARCHAR field is [field length]
+ 1 bytes, up to max length 255, so I wouldn't worry too much about trying to find a perfect size. Take a look at what you'd imagine might be the longest length might be, then double it and set that as your VARCHAR limit. That said...:
I generally set email fields to be VARCHAR(100) - i haven't come up with a problem from that yet. Names I set to VARCHAR(50).
As the others have said, phone numbers and zip/postal codes are not actually numeric values, they're strings containing the digits 0-9 (and sometimes more!), and therefore you should treat them as a string. VARCHAR(20) should be well sufficient.
Note that if you were to store phone numbers as integers, many systems will assume that a number starting with 0 is an octal (base 8) number! Therefore, the perfectly valid phone number "0731602412" would get put into your database as the decimal number "124192010"!!
Throwing in another solution.
In my module's init.py I have something like:
# mymodule/__init__.py
import logging
def get_module_logger(mod_name):
logger = logging.getLogger(mod_name)
handler = logging.StreamHandler()
formatter = logging.Formatter(
'%(asctime)s %(name)-12s %(levelname)-8s %(message)s')
handler.setFormatter(formatter)
logger.addHandler(handler)
logger.setLevel(logging.DEBUG)
return logger
Then in each module I need a logger, I do:
# mymodule/foo.py
from [modname] import get_module_logger
logger = get_module_logger(__name__)
When the logs are missed, you can differentiate their source by the module they came from.
Another thing you can do is just drag a folder from your computer into the GitHub repository page. This folder does have to have at least 1 item in it, though.
To my knowledge, StackOverflow has lots of people asking this question in various ways, but nobody has answered it completely yet.
My spec called for the user to be able to choose email, twitter, facebook, or SMS, with custom text for each one. Here is how I accomplished that:
public void onShareClick(View v) {
Resources resources = getResources();
Intent emailIntent = new Intent();
emailIntent.setAction(Intent.ACTION_SEND);
// Native email client doesn't currently support HTML, but it doesn't hurt to try in case they fix it
emailIntent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(resources.getString(R.string.share_email_native)));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.share_email_subject));
emailIntent.setType("message/rfc822");
PackageManager pm = getPackageManager();
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
Intent openInChooser = Intent.createChooser(emailIntent, resources.getString(R.string.share_chooser_text));
List<ResolveInfo> resInfo = pm.queryIntentActivities(sendIntent, 0);
List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();
for (int i = 0; i < resInfo.size(); i++) {
// Extract the label, append it, and repackage it in a LabeledIntent
ResolveInfo ri = resInfo.get(i);
String packageName = ri.activityInfo.packageName;
if(packageName.contains("android.email")) {
emailIntent.setPackage(packageName);
} else if(packageName.contains("twitter") || packageName.contains("facebook") || packageName.contains("mms") || packageName.contains("android.gm")) {
Intent intent = new Intent();
intent.setComponent(new ComponentName(packageName, ri.activityInfo.name));
intent.setAction(Intent.ACTION_SEND);
intent.setType("text/plain");
if(packageName.contains("twitter")) {
intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_twitter));
} else if(packageName.contains("facebook")) {
// Warning: Facebook IGNORES our text. They say "These fields are intended for users to express themselves. Pre-filling these fields erodes the authenticity of the user voice."
// One workaround is to use the Facebook SDK to post, but that doesn't allow the user to choose how they want to share. We can also make a custom landing page, and the link
// will show the <meta content ="..."> text from that page with our link in Facebook.
intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_facebook));
} else if(packageName.contains("mms")) {
intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_sms));
} else if(packageName.contains("android.gm")) { // If Gmail shows up twice, try removing this else-if clause and the reference to "android.gm" above
intent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(resources.getString(R.string.share_email_gmail)));
intent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.share_email_subject));
intent.setType("message/rfc822");
}
intentList.add(new LabeledIntent(intent, packageName, ri.loadLabel(pm), ri.icon));
}
}
// convert intentList to array
LabeledIntent[] extraIntents = intentList.toArray( new LabeledIntent[ intentList.size() ]);
openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
startActivity(openInChooser);
}
I found bits of how to do this in various places, but I haven't seen all of it in one place anywhere else.
Note that this method also hides all the silly options that I don't want, like sharing over wifi and bluetooth.
Hope this helps someone.
Edit:
In a comment, I was asked to explain what this code is doing. Basically, it's creating an ACTION_SEND
intent for the native email client ONLY, then tacking other intents onto the chooser. Making the original intent email-specific gets rid of all the extra junk like wifi and bluetooth, then I grab the other intents I want from a generic ACTION_SEND
of type plain-text, and tack them on before showing the chooser.
When I grab the additional intents, I set custom text for each one.
Edit2: It's been awhile since I posted this, and things have changed a bit. If you are seeing gmail twice in the list of options, try removing the special handling for "android.gm" as suggested in a comment by @h_k below.
Since this one answer is the source of nearly all my stackoverflow reputation points, I have to at least try to keep it up to date.
Since milliseconds are not updated every millisecond in node, following is an answer. This generates a unique human readable ticket number. I am new to programming and nodejs. Please correct me if I am wrong.
function get2Digit(value) {
if (value.length == 1) return "0" + "" + value;
else return value;
}
function get3Digit(value) {
if (value.length == 1) return "00" + "" + value;
else return value;
}
function generateID() {
var d = new Date();
var year = d.getFullYear();
var month = get2Digit(d.getMonth() + 1);
var date = get2Digit(d.getDate());
var hours = get2Digit(d.getHours());
var minutes = get2Digit(d.getMinutes());
var seconds = get2Digit(d.getSeconds());
var millSeconds = get2Digit(d.getMilliseconds());
var dateValue = year + "" + month + "" + date;
var uniqueID = hours + "" + minutes + "" + seconds + "" + millSeconds;
if (lastUniqueID == "false" || lastUniqueID < uniqueID) lastUniqueID = uniqueID;
else lastUniqueID = Number(lastUniqueID) + 1;
return dateValue + "" + lastUniqueID;
}
Looks like the type is boolean and therefore can never be null and should be false by default.
If you're running your script in a virtual environment, say venv
, then executing which python
while working on venv
will display the path to the Python interpreter:
~/Envs/venv/bin/python
Note that the name of the virtual environment is embedded in the path to the Python interpreter. Therefore, hardcoding this path in your script will cause two problems:
Therefore, to add to Jonathan's answer, the ideal shebang is #!/usr/bin/env python
, not just for portability across OSes but for portability across virtual environments as well!
What exactly are the rules for requesting retransmission of lost data?
The receiver does not request the retransmission. The sender waits for an ACK for the byte-range sent to the client and when not received, resends the packets, after a particular interval. This is ARQ (Automatic Repeat reQuest). There are several ways in which this is implemented.
Stop-and-wait ARQ
Go-Back-N ARQ
Selective Repeat ARQ
are detailed in the RFC 3366.
At what time frequency are the retransmission requests performed?
The retransmissions-times and the number of attempts isn't enforced by the standard. It is implemented differently by different operating systems, but the methodology is fixed. (One of the ways to fingerprint OSs perhaps?)
The timeouts are measured in terms of the RTT (Round Trip Time) times. But this isn't needed very often due to Fast-retransmit which kicks in when 3 Duplicate ACKs are received.
Is there an upper bound on the number?
Yes there is. After a certain number of retries, the host is considered to be "down" and the sender gives up and tears down the TCP connection.
Is there functionality for the client to indicate to the server to forget about the whole TCP segment for which part went missing when the IP packet went missing?
The whole point is reliable communication. If you wanted the client to forget about some part, you wouldn't be using TCP in the first place. (UDP perhaps?)

The trick is to just remove the hashtag ASAP and store its value for your own use:
It is important that you do not put that part of the code in the $() or $(window).load() functions as it would be too late and the browser already has moved to the tag.
// store the hash (DON'T put this code inside the $() function, it has to be executed
// right away before the browser can start scrolling!
var target = window.location.hash,
target = target.replace('#', '');
// delete hash so the page won't scroll to it
window.location.hash = "";
// now whenever you are ready do whatever you want
// (in this case I use jQuery to scroll to the tag after the page has loaded)
$(window).on('load', function() {
if (target) {
$('html, body').animate({
scrollTop: $("#" + target).offset().top
}, 700, 'swing', function () {});
}
});
sed 's/[^"]*"\([^"]*\).*/\1/'
does the job.
