For Nginx, the only thing that worked for me was adding this header:
add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since';
Along with the Access-Control-Allow-Origin header:
add_header 'Access-Control-Allow-Origin' '*';
Then reloaded the nginx config and it worked great. Credit https://gist.github.com/algal/5480916.
I got this error while I tried to write to a variable at the same time from different threads. Creating a private queue and making sure one thread at a time can write to that variabele at the same time. It was a dictionary in my case.
To take first 5 elements better use expression like this one:
var firstFiveArrivals = myList.Where([EXPRESSION]).Take(5);
or
var firstFiveArrivals = myList.Where([EXPRESSION]).Take(5).OrderBy([ORDER EXPR]);
It will be faster than orderBy variant, because LINQ engine will not scan trough all list due to delayed execution, and will not sort all array.
class MyList : IEnumerable<int>
{
int maxCount = 0;
public int RequestCount
{
get;
private set;
}
public MyList(int maxCount)
{
this.maxCount = maxCount;
}
public void Reset()
{
RequestCount = 0;
}

public IEnumerator<int> GetEnumerator()
{

while (i < maxCount)
{

yield return i++;
}
}

You can use the dir step, example:
dir("folder") {
sh "pwd"
}
The folder
can be relative or absolute path.
Warning about using TODAY (or any calcs in a column).
If you set up a filter and have JUST [Today] it it you should be fine.
But the moment you do something like [Today]-1 ... the view will no longer show up when trying to pick it for alerts.
Another microsoft wonder.
Here is a workaround using a flag:
//outside your event or method, but inside your class
private bool IsExecuted = false;
private async Task MethodA()
{
//Do Stuff Here
IsExecuted = true;
}
.
.
.
//Inside your event or method
{
await MethodA();
while (!isExecuted) Thread.Sleep(200); // <-------
await MethodB();
}

You can include HTML content. One possibility is encoding it in BASE64 as you have mentioned.
Another might be using CDATA
tags.
Example using CDATA
:
<xml>
<title>Your HTML title</title>
<htmlData><![CDATA[<html>
<head>
<script/>
</head>
<body>
Your HTML's body
</body>
</html>
]]>
</htmlData>
</xml>
Please note:
CDATA's opening character sequence: <![CDATA[
CDATA's closing character sequence: ]]>
Try
gem update --system
Hope it solves the problem.
Justin has correctly shown the expansion in the case where the join is just followed by a select
. If you've got something else, it becomes more tricky due to transparent identifiers - the mechanism the C# compiler uses to propagate the scope of both halves of the join.
So to change Justin's example slightly:
var result = from sc in enumerableOfSomeClass
join soc in enumerableOfSomeOtherClass
on sc.Property1 equals soc.Property2
where sc.X + sc.Y == 10
select new { SomeClass = sc, SomeOtherClass = soc }
would be converted into something like this:
var result = enumerableOfSomeClass
.Join(enumerableOfSomeOtherClass,
sc => sc.Property1,
soc => soc.Property2,
(sc, soc) => new { sc, soc })
.Where(z => z.sc.X + z.sc.Y == 10)
.Select(z => new { SomeClass = z.sc, SomeOtherClass = z.soc });
The z
here is the transparent identifier - but because it's transparent, you can't see it in the original query :)
Thanks to @donut I managed to get the never expiring access token in JavaScript.
// Initialize exchange
fetch('https://graph.facebook.com/v3.2/oauth/access_token?grant_type=fb_exchange_token&client_id={client_id}&client_secret={client_secret}&fb_exchange_token={short_lived_token}')
.then((data) => {
return data.json();
})
.then((json) => {
// Get the user data
fetch(`https://graph.facebook.com/v3.2/me?access_token=${json.access_token}`)
.then((data) => {
return data.json();
})
.then((userData) => {
// Get the page token
fetch(`https://graph.facebook.com/v3.2/${userData.id}/accounts?access_token=${json.access_token}`)
.then((data) => {
return data.json();
})
.then((pageToken) => {
// Save the access token somewhere
// You'll need it at later point
})
.catch((err) => console.error(err))
})
.catch((err) => console.error(err))
})
.catch((err) => {
console.error(err);
})
and then I used the saved access token like this
fetch('https://graph.facebook.com/v3.2/{page_id}?fields=fan_count&access_token={token_from_the_data_array}')
.then((data) => {
return data.json();
})
.then((json) => {
// Do stuff
})
.catch((err) => console.error(err))
I hope that someone can trim this code because it's kinda messy but it was the only way I could think of.
Building and publishing WAPs is not supported if VS is not installed. With that said, if you really do not want to install VS then you will need to copy all the files under %ProgramFiles32%\MSBuild\Microsoft\
.
You will need to install the Web Deploy Tool as well. I think that is it.
remove DEFINER=root

Use
Comparator<File> comparator = Comparator.comparing(File::lastModified);
Collections.sort(list, comparator.reversed());
Then
.forEach(item -> item.delete());
Using LINQ you can do it like this:
var table_enum = table
// Convert to IEnumerable<string>
.OfType<string>()
// Create anonymous type where Index1 and Index2
// reflect the indices of the 2-dim. array
.Select((_string, _index) => new {
Index1 = (_index / 2),
Index2 = (_index % 2), // ? I added this only for completeness
Value = _string
})
// Group by Index1, which generates IEnmurable<string> for all Index1 values
.GroupBy(v => v.Index1)
// Convert all Groups of anonymous type to String-Arrays
.Select(group => group.Select(v => v.Value).ToArray());
// Now you can use the foreach-Loop as you planned
foreach(string[] str_arr in table_enum) {
// …
}
This way it is also possible to use the foreach for looping through the columns instead of the rows by using Index2 in the GroupBy instead of Index 1. If you don't know the dimension of your array then you have to use the GetLength() method to determine the dimension and use that value in the quotient.
I don't know any native cmdlet in powershell but you can use com object instead:
$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut("$Home\Desktop\ColorPix.lnk")
$Shortcut.TargetPath = "C:\Program Files (x86)\ColorPix\ColorPix.exe"
$Shortcut.Save()
you can create a powershell script save as set-shortcut.ps1 in your $pwd
param ( [string]$SourceExe, [string]$DestinationPath )
$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut($DestinationPath)
$Shortcut.TargetPath = $SourceExe
$Shortcut.Save()
and call it like this
Set-ShortCut "C:\Program Files (x86)\ColorPix\ColorPix.exe" "$Home\Desktop\ColorPix.lnk"
If you want to pass arguments to the target exe, it can be done by:
#Set the additional parameters for the shortcut
$Shortcut.Arguments = "/argument=value"
before $Shortcut.Save().
For convenience, here is a modified version of set-shortcut.ps1. It accepts arguments as its second parameter.
param ( [string]$SourceExe, [string]$ArgumentsToSourceExe, [string]$DestinationPath )
$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut($DestinationPath)
$Shortcut.TargetPath = $SourceExe
$Shortcut.Arguments = $ArgumentsToSourceExe
$Shortcut.Save()
One common example for using volatile
is to use a volatile boolean
variable as a flag to terminate a thread. If you've started a thread, and you want to be able to safely interrupt it from a different thread, you can have the thread periodically check a flag. To stop it, set the flag to true. By making the flag volatile
, you can ensure that the thread that is checking it will see it has been set the next time it checks it without having to even use a synchronized
block.
Here is some code I wrote to flatten an object I was working with. It creates a new class that takes every nested field and brings it into the first layer. You could modify it to unflatten by remembering the original placement of the keys. It also assumes the keys are unique even across nested objects. Hope it helps.
class JSONFlattener {
ojson = {}
flattenedjson = {}
constructor(original_json) {
this.ojson = original_json
this.flattenedjson = {}
this.flatten()
}
flatten() {
Object.keys(this.ojson).forEach(function(key){
if (this.ojson[key] == null) {
} else if (this.ojson[key].constructor == ({}).constructor) {
this.combine(new JSONFlattener(this.ojson[key]).returnJSON())
} else {
this.flattenedjson[key] = this.ojson[key]
}
}, this)
}
combine(new_json) {
//assumes new_json is a flat array
Object.keys(new_json).forEach(function(key){
if (!this.flattenedjson.hasOwnProperty(key)) {
this.flattenedjson[key] = new_json[key]
} else {
console.log(key+" is a duplicate key")
}
}, this)
}
returnJSON() {
return this.flattenedjson
}
}
console.log(new JSONFlattener(dad_dictionary).returnJSON())
As an example, it converts
nested_json = {
"a": {
"b": {
"c": {
"d": {
"a": 0
}
}
}
},
"z": {
"b":1
},
"d": {
"c": {
"c": 2
}
}
}
into
{ a: 0, b: 1, c: 2 }

Here's my little class that can reprint blocks of text. It properly clears the previous text so you can overwrite your old text with shorter new text without creating a mess.
import re, sys
class Reprinter:
def __init__(self):
self.text = ''
def moveup(self, lines):
for _ in range(lines):
sys.stdout.write("\x1b[A")
def reprint(self, text):
# Clear previous text by overwritig non-spaces with spaces
self.moveup(self.text.count("\n"))
sys.stdout.write(re.sub(r"[^\s]", " ", self.text))
# Print new text
lines = min(self.text.count("\n"), text.count("\n"))
self.moveup(lines)
sys.stdout.write(text)
self.text = text
reprinter = Reprinter()
reprinter.reprint("Foobar\nBazbar")
reprinter.reprint("Foo\nbar")

May I suggest that you initialize your "max and min so far" variables not to infinity, but to the first number in the array?
This is your code
$q = $this -> db
-> select('id')
-> where('email', $email)
-> limit(1)
-> get('users');
Try this
$id = $q->result()[0]->id;
or this one, it's simpler
$id = $q->row()->id;
There is a small issue in the First two configurations i think. The concepts of threads and cores like follows. The concept of threading is if the cores are ideal then use that core to process the data. So the memory is not fully utilized in first two cases. If you want to bench mark this example choose the machines which has more than 10 cores on each machine. Then do the bench mark.
But dont give more than 5 cores per executor there will be bottle neck on i/o performance.
So the best machines to do this bench marking might be data nodes which have 10 cores.
Data node machine spec: CPU: Core i7-4790 (# of cores: 10, # of threads: 20) RAM: 32GB (8GB x 4) HDD: 8TB (2TB x 4)
Neither <iostream>
nor <iostream.h>
are standard C header files. Your code is meant to be C++, where <iostream>
is a valid header. Use g++
(and a .cpp
file extension) for C++ code.
Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream>
and using namespace std;
, and replace cout << endl;
with putchar('\n');
... I advise compiling using C99 (eg. gcc -std=c99
)
To understand pid files, refer this DOC
Some times there are certain applications that require additional support of extra plugins and utilities. So it keeps track of these utilities and plugin process running ids using this pid file for reference.
That is why whenever you restart an application all necessary plugins and dependant apps must be restarted since the pid file will become stale.

Another way.
I was able to solve this using local_action to scp to file from machineA to machineC and then copying the file to machineB.
In Controller
if (MyModal.ImageFile != null)
{
MyModal.ImageURL = string.Format("{0}.{1}", Guid.NewGuid().ToString(), MyModal.ImageFile.FileName.Split('.').LastOrDefault());
if (MyModal.ImageFile != null)
{
var path = Path.Combine(Server.MapPath("~/Content/uploads/"), MyModal.ImageURL);
MyModal.ImageFile.SaveAs(path);
}
}
In View
<input type="hidden" value="" name="..."><input id="ImageFile" type="file" name="ImageFile" src="@Model.ImageURL">
In Modal Class
public HttpPostedFileBase ImageFile { get; set; }
Create a folder as uploads in Content folder in project
Maybe you can try this way
function myFunction()
{
$("select[id^=myID]").attr("disabled", true);
var txtSelect = $("select[id^=myID] option[selected]").text();
}
This sets the first value of the drop-down as the default and it seems readonly
This can also be accomplished with a while loop which checks to see if any documents remain that still have subdocuments that have not been updated. This method preserves the atomicity of your updates (which many of the other solutions here do not).
var query = {
events: {
$elemMatch: {
profile: 10,
handled: { $ne: 0 }
}
}
};
while (db.yourCollection.find(query).count() > 0) {
db.yourCollection.update(
query,
{ $set: { "events.$.handled": 0 } },
{ multi: true }
);
}
The number of times the loop is executed will equal the maximum number of times subdocuments with profile
equal to 10 and handled
not equal to 0 occur in any of the documents in your collection. So if you have 100 documents in your collection and one of them has three subdocuments that match query
and all the other documents have fewer matching subdocuments, the loop will execute three times.
This method avoids the danger of clobbering other data that may be updated by another process while this script executes. It also minimizes the amount of data being transferred between client and server.
Just because I did not see it mentioned.
If 2016+, here is yet another option to dynamically unpivot data without actually using Dynamic SQL.
Example
Declare @YourTable Table ([ID] varchar(50),[Col1] varchar(50),[Col2] varchar(50))
Insert Into @YourTable Values
(1,'A','B')
,(2,'R','C')
,(3,'X','D')
Select A.[ID]
,Item = B.[Key]
,Value = B.[Value]
From @YourTable A
Cross Apply ( Select *
From OpenJson((Select A.* For JSON Path,Without_Array_Wrapper ))
Where [Key] not in ('ID','Other','Columns','ToExclude')
) B
Returns
ID Item Value
1 Col1 A
1 Col2 B
2 Col1 R
2 Col2 C
3 Col1 X
3 Col2 D
There are three ways:
Use SFTP plugin (commercial) http://wbond.net/sublime_packages/sftp - I personally recommend this, as after settings public SSH keys with passphrase it is safe, easy and worth every penny http://opensourcehacker.com/2012/10/24/ssh-key-and-passwordless-login-basics-for-developers/
Mount the remote as local file system using osxfuse
and sshfs
as mentioned in the comments. This might be little difficult, depending on OSX version and your skills with UNIX file systems.
Hack together something like rmate which does file editing over remote tunneling using some kind of a local daemon (very difficult, cumbersome, but sudo compatible) http://blog.macromates.com/2011/mate-and-rmate/
Also, in theory, you can install X11 on the remote server and run Sublime there over VNC or X11 forwarding, but there would be no point doing this.
Just Try in button.

I usually use this workaround:
try:
from .mymodule import myclass
except Exception: #ImportError
from mymodule import myclass
Which means your IDE should pick up the right code location and the python interpreter will manage to run your code.
The reason for using dictionaries in the first place is performance. Although it is correct that you can use named vectors and lists for the task the issue is that they are becoming quite slow and memory hungry with more data.
Yet what many people don't know is that R has indeed an inbuilt dictionary data structure: environments with the option hash = TRUE
See the following example for how to make it work:
# vectorize assign, get and exists for convenience
assign_hash <- Vectorize(assign, vectorize.args = c("x", "value"))
get_hash <- Vectorize(get, vectorize.args = "x")
exists_hash <- Vectorize(exists, vectorize.args = "x")
# keys and values
key<- c("tic", "tac", "toe")
value <- c(1, 22, 333)
# initialize hash
hash = new.env(hash = TRUE, parent = emptyenv(), size = 100L)
# assign values to keys
assign_hash(key, value, hash)
## tic tac toe
## 1 22 333
# get values for keys
get_hash(c("toe", "tic"), hash)
## toe tic
## 333 1
# alternatively:
mget(c("toe", "tic"), hash)
## $toe
## [1] 333
##
## $tic
## [1] 1
# show all keys
ls(hash)
## [1] "tac" "tic" "toe"
# show all keys with values
get_hash(ls(hash), hash)
## tac tic toe
## 22 1 333
# remove key-value pairs
rm(list = c("toe", "tic"), envir = hash)
get_hash(ls(hash), hash)
## tac
## 22
# check if keys are in hash
exists_hash(c("tac", "nothere"), hash)
## tac nothere
## TRUE FALSE
# for single keys this is also possible:
# show value for single key
hash[["tac"]]
## [1] 22
# create new key-value pair
hash[["test"]] <- 1234
get_hash(ls(hash), hash)
## tac test
## 22 1234
# update single value
hash[["test"]] <- 54321
get_hash(ls(hash), hash)
## tac test
## 22 54321
Edit: On the basis of this answer I wrote a blog post with some more context: http://blog.ephorie.de/hash-me-if-you-can
In order to call this you will have to store a reference to your form and pass the reference to the run method. Then you can call this in an actionhandler.
public partial class Form1 : Form
{
public void ChangeSize(int width, int height)
{
this.Size = new Size(width, height);
}
}
I would turn it into a json object, with the added benefit of keeping the keys if you are using an associative array:
$stringRepresentation= json_encode($arr);
You're using the exec form of ENTRYPOINT. Unlike the shell form, the exec form does not invoke a command shell. This means that normal shell processing does not happen. For example, ENTRYPOINT [ "echo", "$HOME" ]
will not do variable substitution on $HOME. If you want shell processing then either use the shell form or execute a shell directly, for example: ENTRYPOINT [ "sh", "-c", "echo $HOME" ]
.
When using the exec form and executing a shell directly, as in the case for the shell form, it is the shell that is doing the environment variable expansion, not docker.(from Dockerfile reference)
In your case, I would use shell form
ENTRYPOINT ./greeting --message "Hello, $ADDRESSEE\!"
Here's an ugly solution for you:
var date = new Date(new Date().setDate(new Date().getDate() - 30));
#!/bin/sh
WID=$(xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)"| awk '{print $5}')
xdotool windowfocus $WID
xdotool key ctrl+shift+t
wmctrl -i -a $WID
This will auto determine the corresponding terminal and opens the tab accordingly.
Actually, the correct solution is:
composer require vendor/package
Taken from the CLI documentation for Composer:
The
require
command adds new packages to thecomposer.json
file from the current directory.
php composer.phar require
After adding/changing the requirements, the modified requirements will be installed or updated.
If you do not want to choose requirements interactively, you can just pass them to the command.
php composer.phar require vendor/package:2.* vendor/package2:dev-master
While it is true that composer update
installs new packages found in composer.json, it will also update the composer.lock file and any installed packages according to any fuzzy logic (>
or *
chars after the colons) found in composer.json! This can be avoided by using composer update vendor/package
, but I wouldn't recommend making a habit of it, as you're one forgotten argument away from a potentially broken project…
Keep things sane and stick with composer require vendor/package
for adding new dependencies!

case (x < 9):
alert("between 5 and 8");
break;
case (x < 12):
alert("between 9 and 11");
break;
default:
alert("none");
break;
}
It is not necessary to check the lower end of the range because the break
statements will cause execution to skip remaining cases, so by the time execution gets to checking e.g. (x < 9) we know the value must be 5 or greater.
Of course the output is only correct if the cases stay in the original order, and we assume integer values (as stated in the question) - technically the ranges are between 5 and 8.999999999999 or so since all numbers in js are actually double-precision floating point numbers.
If you want to be able to move the cases around, or find it more readable to have the full range visible in each case statement, just add a less-than-or-equal check for the lower range of each case:
var x = this.dealer;
switch (true) {
case (x < 5):
alert("less than five");
break;
case (x >= 5 && x < 9):
alert("between 5 and 8");
break;
case (x >= 9 && x < 12):
alert("between 9 and 11");
break;
default:
alert("none");
break;
}
Keep in mind that this adds an extra point of human error - someone may try to update a range, but forget to change it in both places, leaving an overlap or gap that is not covered. e.g. here the case of 8 will now not match anything when I just edit the case that used to match 8.
case (x >= 5 && x < 8):
alert("between 5 and 7");
break;
case (x >= 9 && x < 12):
alert("between 9 and 11");
break;

I believe it's because it can execute any JavaScript function from a string. Using it makes it easier for people to inject rogue code into the application.
Just for reference, using ddrescue provides an interruptible way of achieving the task if, for example, you have large files and the need to pause and then carry on at some later point:
ddrescue -o $(wc --bytes file1 | awk '{ print $1 }') file2 file1 logfile
The logfile
is the important bit. You can interrupt the process with Ctrl-C
and resume it by specifying the exact same command again and ddrescue will read logfile
and resume from where it left off. The -o A
flag tells ddrescue to start from byte A in the output file (file1
). So wc --bytes file1 | awk '{ print $1 }'
just extracts the size of file1
in bytes (you can just paste in the output from ls
if you like).
As pointed out by ngks in the comments, the downside is that ddrescue will probably not be installed by default, so you will have to install it manually. The other complication is that there are two versions of ddrescue which might be in your repositories: see this askubuntu question for more info. The version you want is the GNU ddrescue, and on Debian-based systems is the package named gddrescue
:
sudo apt install gddrescue
For other distros check your package management system for the GNU version of ddrescue.
x(end+1) = newElem
is a bit more robust.
x = [x newElem]
will only work if x
is a row-vector, if it is a column vector x = [x; newElem]
should be used. x(end+1) = newElem
, however, works for both row- and column-vectors.
In general though, growing vectors should be avoided. If you do this a lot, it might bring your code down to a crawl. Think about it: growing an array involves allocating new space, copying everything over, adding the new element, and cleaning up the old mess...Quite a waste of time if you knew the correct size beforehand :)
For small arrays use array initialisation syntax:
var sevenItems = new byte[] { 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20 };
For larger arrays use a standard for
loop. This is the most readable and efficient way to do it:
var sevenThousandItems = new byte[7000];
for (int i = 0; i < sevenThousandItems.Length; i++)
{
sevenThousandItems[i] = 0x20;
}
Of course, if you need to do this a lot then you could create a helper method to help keep your code concise:
byte[] sevenItems = CreateSpecialByteArray(7);
byte[] sevenThousandItems = CreateSpecialByteArray(7000);
// ...
public static byte[] CreateSpecialByteArray(int length)
{
var arr = new byte[length];
for (int i = 0; i < arr.Length; i++)
{
arr[i] = 0x20;
}
return arr;
}
Use BOOST_BINARY (Yes, you can use it in C).
#include <boost/utility/binary.hpp>
...
int bin = BOOST_BINARY(110101);
This macro is expanded to an octal literal during preprocessing.
I assume I have import datetime
before running each of the lines of code below
datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')
prints "01/25/13"
.
If you can't live with the leading zero, try this:
dt = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print '{0}/{1}/{2:02}'.format(dt.month, dt.day, dt.year % 100)
This prints "1/25/13"
.
EDIT: This may not work on every platform:
datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')
if (array[0]=1)
should be if (array[0]==1)
.
The same with else if (array[0]=2)
.
Note that the expression of the assignment returns the assigned value, in this case if (array[0]=1)
will be always true, that's why the code below the if-statement will be always executed if you don't change the =
to ==
.
=
is the assignment operator, you want to compare, not to assign. So you need ==
.
Another thing, if you want only one integer, why are you using array? You might want also to scanf("%d", &array[0]);
Actually.
Why are you checking the URL? That's no guarantee what you're going to get is an image, and no guarantee that the things you're rejecting aren't images. Try performing a HEAD request on it, and see what content-type it actually is.

To see exactly what is happening, use nc -l
and an user agent like a browser or cURL.
Save the form to an .html
file:
<form action="http://localhost:8000" method="post" enctype="multipart/form-data">
<p><input type="text" name="text" value="text default">
<p><input type="file" name="file1">
<p><input type="file" name="file2">
<p><button type="submit">Submit</button>
</form>
Create files to upload:
echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html
Run:
nc -l localhost 8000
Open the HTML on your browser, select the files and click on submit and check the terminal.
nc
prints the request received. Firefox sent:

Aternativelly, cURL should send the same POST request as your a browser form:
nc -l localhost 8000
curl -F "text=default" -F "[email protected]" -F "[email protected]" localhost:8000
You can do multiple tests with:
while true; do printf '' | nc -l localhost 8000; done
@bhamby is correct. By leaving the microseconds off of your timestamp value, your query would only match on a usagetime of 2012-09-03 08:03:06.000000
If you don't have the complete timestamp value captured from a previous query, you can specify a ranged predicate that will match on any microsecond value for that time:
...WHERE id = 1 AND usagetime BETWEEN '2012-09-03 08:03:06' AND '2012-09-03 08:03:07'
or
...WHERE id = 1 AND usagetime >= '2012-09-03 08:03:06'
AND usagetime < '2012-09-03 08:03:07'

All of the information you are looking for can be found here and here (thanks Reed Copsey):
From the first link:
Classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs) can be either public or internal. Internal is the default if no access modifier is specified.
...
The access level for class members and struct members, including nested classes and structs, is private by default.
...
interfaces default to internal access.
...
Delegates behave like classes and structs. By default, they have internal access when declared directly within a namespace, and private access when nested.
From the second link:
Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.
And for nested types:
Members of Default member accessibility ---------- ---------------------------- enum public class private interface public struct private
In your root project directory
Make sure you have already directory android/app/src/main/assets/, if not create directory, after that create new file and save as index.android.bundle
and put your file in like this android/app/src/main/assets/index.android.bundle
After that run this
react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/
cd android && ./gradlew assembleDebug
Then you can get apk
in app/build/outputs/apk/debug/app-debug.apk
I think you want to lowercase the checked value? Try:
var jIsHasKids = $('#chkIsHasKids:checked').val().toLowerCase();
or you want to check it, then get its value as lowercase:
var jIsHasKids = $('#chkIsHasKids').attr("checked", true).val().toLowerCase();
Use int
function with second parameter 16, to convert a hex string to an integer. Finally, use hex
function to convert it back to a hexadecimal number.
print hex(int("0xAD4", 16) + int("0x200", 16)) # 0xcd4
Instead you could directly do
print hex(int("0xAD4", 16) + 0x200) # 0xcd4
I got this when I didn't type things right. I had
__init.py__
instead of
__init__.py
So many problems in so few lines. I probably forget some:

#include <stdio.h>
int main(int argc, char* argv[])
{
char const* const fileName = argv[1]; /* should check that argc > 1 */
FILE* file = fopen(fileName, "r"); /* should check the result */
char line[256];
while (fgets(line, sizeof(line), file)) {
/* note that fgets don't strip the terminating \n, checking its
presence would allow to handle lines longer that sizeof(line) */
printf("%s", line);
}
/* may check feof here to make a difference between eof and io failure -- network
timeout for instance */
fclose(file);
return 0;
}

Your issue is not really with Angular, but with Array methods. The proper way to remove a particularly item from an array is with Array.splice
. Also, when using ng-repeat, you have access to the special $index
property, which is the current index of the array you passed in.
The solution is actually pretty straightforward:
View:
<a ng-click="delete($index)">Delete</a>
Controller:
$scope.delete = function ( idx ) {
var person_to_delete = $scope.persons[idx];
API.DeletePerson({ id: person_to_delete.id }, function (success) {
$scope.persons.splice(idx, 1);
});
};

Say you have an HRC file containing the syntax and lexical structure of some programming language Eclipse does not support (for example D / Iptables or any other script language).
Using the EclipseColorer plugin, you can easily add support for it.
Go to Help -> Install New Software and click Add.. In the Name field write Colorer and in the Location field write http://colorer.sf.net/eclipsecolorer/
Select the entry you’ve just added in the work with: combo box, wait for the component list to populate and click Select All
Click Next and follow the instructions
Once the plugin is installed, close Eclipse.
Copy your HRC file to [EclipseFolder]\plugins\net.sf.colorer_0.9.9\colorer\hrc\auto\types
[EclipseFolder] = /home/myusername/.eclipse
Use your favorite text editor to open
[EclipseFolder]\plugins\net.sf.colorer_0.9.9\colorer\hrc\auto\empty.hrc
Add the appropriate prototype element. For example, if your HRC file is d.hrc, empty.hrc will look like this:
<?xml version="1.0" encoding='Windows-1251'?>
<!DOCTYPE hrc PUBLIC
"-//Cail Lomecb//DTD Colorer HRC take5//EN"
"http://colorer.sf.net/2003/hrc.dtd"
>
<hrc version="take5" xmlns="http://colorer.sf.net/2003/hrc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://colorer.sf.net/2003/hrc http://colorer.sf.net/2003/hrc.xsd"
><annotation><documentation>
'auto' is a place for include
to colorer your own HRCs
</documentation></annotation>
<prototype name="d" group="main" description="D">
<location link="types/d.hrc"/>
<filename>/\.(d)$/i</filename>
</prototype>
</hrc>
Save the changes and close the text editor
Open Eclipse and go to Window -> Preferences -> General -> Editors -> File Associations
In the file types section, click Add.. and fill in the appropriate filetype (for example .d)
Click OK and click your newly added entry in the list
In the associated editors section, click Add.., select Colorer Editor and press OK
ok, the hard part is you must learn about HCR syntax.
You can look in
[EclipseFolder]/net.sf.colorer_0.9.9/colorer/hrc/common.jar
to learn how do it and explore many other hcr's files. At this moment I didn't find any documentation.
My gift is a basic and incomplete iptables syntax highlight. If you improve please share with me.

After this you must save the file as iptables.hcr and add inside the jar:
[EclipseFolder]/net.sf.colorer_0.9.9/colorer/hrc/common.jar
Convert.ToInt32(string, base)
does not do base conversion into your base. It assumes that the string contains a valid number in the indicated base, and converts to base 10.
So you're getting an error because "8" is not a valid digit in base 2.
String str = "1111";
String Ans = Convert.ToInt32(str, 2).ToString();
Will show 15
(1111 base 2 = 15 base 10)
String str = "f000";
String Ans = Convert.ToInt32(str, 16).ToString();
Will show 61440
.
I've placed this code in the document ready function and it only triggers in internet explorer. Tested in Internet Explorer 11.
var ua = window.navigator.userAgent;
ms_ie = /MSIE|Trident/.test(ua);
if ( ms_ie ) {
//Do internet explorer exclusive behaviour here
}
In PHP using double quotes causes a slight decrease in performance because variable names are evaluated, so in practice, I always use single quotes when writing code:
echo "This will print you the value of $this_variable!";
echo 'This will literally say $this_variable with no evaluation.';
So you can write this instead;
echo 'This will show ' . $this_variable . '!';
I believe Javascript functions similarly, so a very tiny improvement in performance, if that matters to you.
Additionally, if you look all the way down to HTML spec 2.0, all the tags listed here;
(Use doublequotes.) Consistency is important no matter which you tend to use more often.
Though you have to be careful. It is not clearly said in your intro, if you are looking only at latine language. Some words can become meaningless or another meaning if you sanitize them with ascii characters only.
imagine you have "forêt poésie" (forest poetry), your sanitization might give "fort-posie" (strong + something meaningless)
Worse if you have to deal with chinese characters.
"???" your system might end up doing "---" which is doomed to fail after a while and not very helpful. So if you deal with only files I would encourage to either call them a generic chain that you control or to keep the characters as it is. For URIs, about the same.
The pattern matches all non-digit characters. This will restrict you to non-negative integers, but for your example it will be more than sufficient.
string input = "0, 10, 20, 30, 100, 200";
Regex.Split(input, @"\D+");
As people already mentioned, it could be internet problems or proxy configuration.
I found this question when I was searching about the same problem. In my case, it was proxy configuration.
Answers posted here didn't solve my issue, because every link suggest a configuration that shows the username and passoword and I can't use it.
I was searching about it elsewere and I found a configuration to be made on settings.xml, I needed to make some changes. Here is the final code:
<profiles>
<profile>
<id>MavenRepository</id>
<repositories>
<repository>

I hope be useful.
When we create new types by defining classes, we can take advantage of certain features of Python to make the new classes convenient to use. One of these features is "special methods", also referred to as "magic methods".
Special methods have names that begin and end with two underscores. We define them, but do not usually call them directly by name. Instead, they execute automatically under under specific circumstances.
It is convenient to be able to output the value of an instance of an object by using a print statement. When we do this, we would like the value to be represented in the output in some understandable unambiguous format. The repr special method can be used to arrange for this to happen. If we define this method, it can get called automatically when we print the value of an instance of a class for which we defined this method. It should be mentioned, though, that there is also a str special method, used for a similar, but not identical purpose, that may get precedence, if we have also defined it.
If we have not defined, the repr method for the Point3D class, and have instantiated my_point as an instance of Point3D, and then we do this ...
print my_point ... we may see this as the output ...
Not very nice, eh?
So, we define the repr or str special method, or both, to get better output.
**class Point3D(object):
def __init__(self,a,b,c):
self.x = a
self.y = b
self.z = c
def __repr__(self):
return "Point3D(%d, %d, %d)" % (self.x, self.y, self.z)
def __str__(self):
return "(%d, %d, %d)" % (self.x, self.y, self.z)
my_point = Point3D(1, 2, 3)
print my_point # __repr__ gets called automatically
print my_point # __str__ gets called automatically**
Output ...
(1, 2, 3) (1, 2, 3)

NewScores is an alias to Scores table - it looks like you can combine the queries as follows:
SELECT
ROW_NUMBER() OVER( ORDER BY NETT) AS Rank,
Name,
FlagImg,
Nett,
Rounds
FROM (
SELECT
Members.FirstName + ' ' + Members.LastName AS Name,
CASE
WHEN MenuCountry.ImgURL IS NULL THEN
'~/images/flags/ismygolf.png'
ELSE
MenuCountry.ImgURL
END AS FlagImg,
AVG(CAST(NewScores.NetScore AS DECIMAL(18, 4))) AS Nett,
COUNT(Score.ScoreID) AS Rounds
FROM
Members
INNER JOIN
Score NewScores
ON Members.MemberID = NewScores.MemberID
LEFT OUTER JOIN MenuCountry
ON Members.Country = MenuCountry.ID
WHERE
Members.Status = 1
AND NewScores.InsertedDate >= DATEADD(mm, -3, GETDATE())
GROUP BY
Members.FirstName + ' ' + Members.LastName,
MenuCountry.ImgURL
) AS Dertbl
ORDER BY;
There's an easy, old-fashioned way to store user credentials in an HTTPS URL:
https://user:[email protected]/...
You can change the URL with git remote set-url <remote-repo> <URL>
The obvious downside to that approach is that you have to store the password in plain text. You can still just enter the user name (https://[email protected]/...
) which will at least save you half the hassle.
You might prefer to switch to SSH or to use the GitHub client software.
easy:
launching activity (onclick handler)
Intent myIntent = new Intent(CurrentActivity.this, NextActivity.class);
myIntent.putExtra("key", value); //Optional parameters
CurrentActivity.this.startActivity(myIntent);
on the new activity:
@Override
protected void onCreate(Bundle savedInstanceState) {
Intent intent = getIntent();
String value = intent.getStringExtra("key"); //if it's a string you stored.
and add your new activity in the AndroidManifest.xml:
<activity android:label="@string/app_name" android:name="NextActivity"/>
TCO (Tail Call Optimization) is the process by which a smart compiler can make a call to a function and take no additional stack space. The only situation in which this happens is if the last instruction executed in a function f is a call to a function g (Note: g can be f). The key here is that f no longer needs stack space - it simply calls g and then returns whatever g would return. In this case the optimization can be made that g just runs and returns whatever value it would have to the thing that called f.
This optimization can make recursive calls take constant stack space, rather than explode.
Example: this factorial function is not TCOptimizable:
def fact(n):
if n == 0:
return 1
return n * fact(n-1)
This function does things besides call another function in its return statement.
This below function is TCOptimizable:
def fact_h(n, acc):
if n == 0:
return acc
return fact_h(n-1, acc*n)
def fact(n):
return fact_h(n, 1)
This is because the last thing to happen in any of these functions is to call another function.
This code puts the above all together and restarts the current wpf app with admin privs:
if (IsAdministrator() == false)
{
// Restart program and run as admin
var exeName = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName;
ProcessStartInfo startInfo = new ProcessStartInfo(exeName);
startInfo.Verb = "runas";
System.Diagnostics.Process.Start(startInfo);
Application.Current.Shutdown();
return;
}
private static bool IsAdministrator()
{
WindowsIdentity identity = WindowsIdentity.GetCurrent();
WindowsPrincipal principal = new WindowsPrincipal(identity);
return principal.IsInRole(WindowsBuiltInRole.Administrator);
}
// To run as admin, alter exe manifest file after building.
// Or create shortcut with "as admin" checked.
// Or ShellExecute(C# Process.Start) can elevate - use verb "runas".
// Or an elevate vbs script can launch programs as admin.
// (does not work: "runas /user:admin" from cmd-line prompts for admin pass)
Update: The app manifest way is preferred:
Right click project in visual studio, add, new application manifest file, change the file so you have requireAdministrator set as shown in the above.
A problem with the original way: If you put the restart code in app.xaml.cs OnStartup, it still may start the main window briefly even though Shutdown was called. My main window blew up if app.xaml.cs init was not run and in certain race conditions it would do this.
Because most of solutions is bit outdated I could also suggest asciitable which already available in maven (de.vandermeer:asciitable:0.3.2
) and may produce very complicated configurations.
And usage still looks easy:
AsciiTable at = new AsciiTable();
at.addRule();
at.addRow("row 1 col 1", "row 1 col 2");
at.addRule();
at.addRow("row 2 col 1", "row 2 col 2");
at.addRule();
System.out.println(at.render()); // Finally, print the table to standard out.
The answer provided by Joe Stefanelli is already correct.
SELECT name FROM (SELECT name FROM agentinformation) as a
We need to make an alias of the subquery because a query needs a table object which we will get from making an alias for the subquery. Conceptually, the subquery results are substituted into the outer query. As we need a table object in the outer query, we need to make an alias of the inner query.
Statements that include a subquery usually take one of these forms:
Check for more subquery rules and subquery types.
More examples of Nested Subqueries.
IN / NOT IN – This operator takes the output of the inner query after the inner query gets executed which can be zero or more values and sends it to the outer query. The outer query then fetches all the matching [IN operator] or non matching [NOT IN operator] rows.
ANY – [>ANY or ANY operator takes the list of values produced by the inner query and fetches all the values which are greater than the minimum value of the list. The
e.g. >ANY(100,200,300), the ANY operator will fetch all the values greater than 100.
e.g. >ALL(100,200,300), the ALL operator will fetch all the values greater than 300.
Depending on your browser support, you could use a css animation. Browser support is IE10 and up for CSS animation. This is nice so you don't have to add jquery UI dependency if its only a small easter egg. If it is integral to your site (aka needed for IE9 and below) go with the jquery UI solution.
.your-animation {
background-color: #fff !important;
-webkit-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
//You have to add the vendor prefix versions for it to work in Firefox, Safari, and Opera.
@-webkit-keyframes your-animation-name {
from { background-color: #5EB4FE;}
to {background-color: #fff;}
}
-moz-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@-moz-keyframes your-animation-name {
from { background-color: #5EB4FE;}
to {background-color: #fff;}
}
-ms-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@-ms-keyframes your-animation-name {
from { background-color: #5EB4FE;}
to {background-color: #fff;}
}
-o-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@-o-keyframes your-animation-name {
from { background-color: #5EB4FE;}
to {background-color: #fff;}
}
animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@keyframes your-animation-name {
from { background-color: #5EB4FE;}
to {background-color: #fff;}
}
Next create a jQuery click event that adds the your-animation
class to the element you wish to animate, triggering the background fading from one color to another:
$(".some-button").click(function(e){
$(".place-to-add-class").addClass("your-animation");
});
Why is it necessary for an interface to be "declared" abstract?
It's not.
public abstract interface Interface {
\___.__/
|
'----> Neither this...
public void interfacing();
public abstract boolean interfacing(boolean really);
\___.__/
|
'----> nor this, are necessary.
}
Interfaces and their methods are implicitly abstract
and adding that modifier makes no difference.
Is there other rules that applies with an abstract interface?
No, same rules apply. The method must be implemented by any (concrete) implementing class.
If abstract is obsolete, why is it included in Java? Is there a history for abstract interface?
Interesting question. I dug up the first edition of JLS, and even there it says "This modifier is obsolete and should not be used in new Java programs".
Okay, digging even further... After hitting numerous broken links, I managed to find a copy of the original Oak 0.2 Specification (or "manual"). Quite interesting read I must say, and only 38 pages in total! :-)
Under Section 5, Interfaces, it provides the following example:
public interface Storing {
void freezeDry(Stream s) = 0;
void reconstitute(Stream s) = 0;
}
And in the margin it says
In the future, the " =0" part of declaring methods in interfaces may go away.
Assuming =0
got replaced by the abstract
keyword, I suspect that abstract
was at some point mandatory for interface methods!

You can check the called
attribute, but if your assertion fails, the next thing you'll want to know is something about the unexpected call, so you may as well arrange for that information to be displayed from the start. Using unittest
, you can check the contents of call_args_list
instead:
self.assertItemsEqual(my_var.call_args_list, [])
When it fails, it gives a message like this:
AssertionError: Element counts were not equal: First has 0, Second has 1: call('first argument', 4)
If you're using old, C-style string instead of the newer, STL-style strings, there's the strlen
function in the C run time library:
const char* p = "Hello";
size_t n = strlen(p);

I guess you will get ORA-01741: illegal zero-length identifier if you use the following
SELECT "" AS Contact FROM Customers;
And if you use the following 2 statements, you will be getting the same null value populated in the column.
SELECT '' AS Contact FROM Customers; OR SELECT null AS Contact FROM Customers;
Assuming that those are Strings, use the convenient static method sort

I don't know if this is safe or not but it worked for me. I kinda ran into this problem myself and tried invalidate()
and requestLayout()
but to no avail. So I just called my onCreate(null)
all over again and it worked. If this is unsafe please do let me know. Hope this helps someone out there.
If you want to pull a particular file from another branch just do
git checkout branch1 -- filenamefoo.txt
This will pull a version of the file from one branch into the current tree
A key pair (the private and public keys) will have the same fingerprint; so in the case you can't remember which private key belong to which public key, find the match by comparing their fingerprints.
The most voted answer by Marvin Vinto provides the fingerprint of a public SSH key file. The fingerprint of the corresponding private SSH key can also be queried, but it requires a longer series of step, as shown below.
Load the SSH agent, if you haven't done so. The easiest way is to invoke
$ ssh-agent bash
or
$ ssh-agent tcsh
(or another shell you use).
Load the private key you want to test:
$ ssh-add /path/to/your-ssh-private-key
You will be asked to enter the passphrase if the key is password-protected.
Now, as others have said, type
$ ssh-add -l
1024 fd:bc:8a:81:58:8f:2c:78:86:a2:cf:02:40:7d:9d:3c you@yourhost (DSA)
fd:bc:...
is the fingerprint you are after. If there are multiple keys, multiple lines will be printed, and the last line contains the fingerprint of the last loaded key.
If you want to stop the agent (i.e., if you invoked step 1 above), then simply type `exit' on the shell, and you'll be back on the shell prior to the loading of ssh agent.
I do not add new information, but hopefully this answer is clear to users of all levels.
Some might find a different kind of input useful: I was given this method of measuring time as part of a university course on GPGPU-programming with NVidia CUDA (course description). It combines methods seen in earlier posts, and I simply post it because the requirements give it credibility:
unsigned long int elapsed;
struct timeval t_start, t_end, t_diff;
gettimeofday(&t_start, NULL);
// perform computations ...
gettimeofday(&t_end, NULL);
timeval_subtract(&t_diff, &t_end, &t_start);
elapsed = (t_diff.tv_sec*1e6 + t_diff.tv_usec);
printf("GPU version runs in: %lu microsecs\n", elapsed);
I suppose you could multiply with e.g. 1.0 / 1000.0
to get the unit of measurement that suits your needs.
I'm pretty sure the terminal in OS X is just like unix, so the command would be:
whoami
I don't have a mac on me at the moment so someone correct me if I'm wrong.
NOTE - The whoami
utility has been obsoleted, and is equivalent to id -un
. It will give you the current user
Seeing that this question is getting quite some upvotes, I add new information (I am not sure if this is new, but I couldn't find it at the time)

Starting from iOS 7, the system always returns the value 02:00:00:00:00:00
when you ask for the MAC address on any device.
In iOS 7 and later, if you ask for the MAC address of an iOS device, the system returns the value 02:00:00:00:00:00. If you need to identify the device, use the identifierForVendor property of UIDevice instead. (Apps that need an identifier for their own advertising purposes should consider using the advertisingIdentifier property of ASIdentifierManager instead.)"

Big task, chances are you shouldn't reinvent the wheel rather using an existing wheel (such as paypal).
However, if you insist on continuing. Start small, you can use a credit card processing facility (Moneris, Authorize.NET) to process credit cards. Most providers have an API you can use. Be wary that you may need to use different providers depending on the card type (Discover, Visa, Amex, Mastercard) and Country (USA, Canada, UK). So build it so that you can communicate with multiple credit card processing APIs.
Security is essential if you are storing credit cards and payment details. Ensure that you are encrypting things properly.
Again, don't reinvent the wheel. You are better off using an existing provider and focussing your development attention on solving an problem that can't easily be purchase.
Android needs to be compiled for every hardware plattform / every device model seperatly with the specific drivers etc. If you manage to do that you need also break the security arrangements every manufacturer implements to prevent the installation of other software - these are also different between each model / manufacturer. So it is possible at in theory, but only there :-)
You can use the cd
builtin, or the pushd
and popd
builtins for this purpose. For example:
# do something with /etc as the working directory
cd /etc
:
# do something with /tmp as the working directory
cd /tmp
:
You use the builtins just like any other command, and can change directory context as many times as you like in a script.
Simply put a file named favicon.ico
in the webroot.
If you want to know more, please start reading:
It represents the scope (the lifetime) of the bean. This is easier to understand if you are familiar with "under the covers" working of a basic servlet web application: How do servlets work? Instantiation, sessions, shared variables and multithreading.
@Request/View/Flow/Session/ApplicationScoped
A @RequestScoped
bean lives as long as a single HTTP request-response cycle (note that an Ajax request counts as a single HTTP request too). A @ViewScoped
bean lives as long as you're interacting with the same JSF view by postbacks which call action methods returning null
/void
without any navigation/redirect. A @FlowScoped
bean lives as long as you're navigating through the specified collection of views registered in the flow configuration file. A @SessionScoped
bean lives as long as the established HTTP session. An @ApplicationScoped
bean lives as long as the web application runs. Note that the CDI @Model
is basically a stereotype for @Named @RequestScoped
, so same rules apply.
Which scope to choose depends solely on the data (the state) the bean holds and represents. Use @RequestScoped
for simple and non-ajax forms/presentations. Use @ViewScoped
for rich ajax-enabled dynamic views (ajaxbased validation, rendering, dialogs, etc). Use @FlowScoped
for the "wizard" ("questionnaire") pattern of collecting input data spread over multiple pages. Use @SessionScoped
for client specific data, such as the logged-in user and user preferences (language, etc). Use @ApplicationScoped
for application wide data/constants, such as dropdown lists which are the same for everyone, or managed beans without any instance variables and having only methods.
Abusing an @ApplicationScoped
bean for session/view/request scoped data would make it to be shared among all users, so anyone else can see each other's data which is just plain wrong. Abusing a @SessionScoped
bean for view/request scoped data would make it to be shared among all tabs/windows in a single browser session, so the enduser may experience inconsitenties when interacting with every view after switching between tabs which is bad for user experience. Abusing a @RequestScoped
bean for view scoped data would make view scoped data to be reinitialized to default on every single (ajax) postback, causing possibly non-working forms (see also points 4 and 5 here). Abusing a @ViewScoped
bean for request, session or application scoped data, and abusing a @SessionScoped
bean for application scoped data doesn't affect the client, but it unnecessarily occupies server memory and is plain inefficient.
Note that the scope should rather not be chosen based on performance implications, unless you really have a low memory footprint and want to go completely stateless; you'd need to use exclusively @RequestScoped
beans and fiddle with request parameters to maintain the client's state. Also note that when you have a single JSF page with differently scoped data, then it's perfectly valid to put them in separate backing beans in a scope matching the data's scope. The beans can just access each other via @ManagedProperty
in case of JSF managed beans or @Inject
in case of CDI managed beans.
@CustomScoped/NoneScoped/Dependent
It's not mentioned in your question, but (legacy) JSF also supports @CustomScoped
and @NoneScoped
, which are rarely used in real world. The @CustomScoped
must refer a custom Map<K, Bean>
implementation in some broader scope which has overridden Map#put()
and/or Map#get()
in order to have more fine grained control over bean creation and/or destroy.
The JSF @NoneScoped
and CDI @Dependent
basically lives as long as a single EL-evaluation on the bean. Imagine a login form with two input fields referring a bean property and a command button referring a bean action, thus with in total three EL expressions, then effectively three instances will be created. One with the username set, one with the password set and one on which the action is invoked. You normally want to use this scope only on beans which should live as long as the bean where it's being injected. So if a @NoneScoped
or @Dependent
is injected in a @SessionScoped
, then it will live as long as the @SessionScoped
bean.
As last, JSF also supports the flash scope. It is backed by a short living cookie which is associated with a data entry in the session scope. Before the redirect, a cookie will be set on the HTTP response with a value which is uniquely associated with the data entry in the session scope. After the redirect, the presence of the flash scope cookie will be checked and the data entry associated with the cookie will be removed from the session scope and be put in the request scope of the redirected request. Finally the cookie will be removed from the HTTP response. This way the redirected request has access to request scoped data which was been prepared in the initial request.
This is actually not available as a managed bean scope, i.e. there's no such thing as @FlashScoped
. The flash scope is only available as a map via ExternalContext#getFlash()
in managed beans and #{flash}
in EL.
Java SE 6 or Java EE 5 provides a method to do this now so there is no need for extra libraries.
The method is DatatypeConverter.parseHexBinary
In this case it can be used as follows:
String str = "9B7D2C34A366BF890C730641E6CECF6F";
byte[] bytes = DatatypeConverter.parseHexBinary(str);
The class also provides type conversions for many other formats that are generally used in XML.
I had this issue for longer than I would like to admit.
I simply just needed to run VS as an administrator, rookie mistake on my part...

The man page makes it pretty clear. If you want to pass two arguments (-rpath
and .
) to the linker you can write
-Wl,-rpath,.
or alternatively
-Wl,-rpath -Wl,.
The arguments -Wl,-rpath .
you suggested do NOT make sense to my mind. How is gcc supposed to know that your second argument (.
) is supposed to be passed to the linker instead of being interpreted normally? The only way it would be able to know that is if it had insider knowledge of all possible linker arguments so it knew that -rpath
required an argument after it.
The following is working code with two ways of achieving this:

You can use a pseudo-element to position as the background of the content with the same image as the background, but blurred with the new CSS3 filter.
You can see it in action here: http://codepen.io/jiserra/pen/JzKpx
I made that for customizing a select, but I added the blur background effect.
Ruby provides another way to handle STDIN: The -n flag. It treats your entire program as being inside a loop over STDIN, (including files passed as command line args). See e.g. the following 1-line script:
#!/usr/bin/env ruby -n
#example.rb
puts "hello: #{$_}" #prepend 'hello:' to each line from STDIN
#these will all work:
# ./example.rb < input.txt
# cat input.txt | ./example.rb
# ./example.rb input.txt
On Django 1.9, I tried django-admin runserver
and got the same error, but when I used python manage.py runserver
I got the intended result. This may solve this error for a lot of people!
You current regex will only match 1 character. you need either * (includes empty string) or + (at least one) to match multiple characters and numbers have a shortcut : \d (need \\ in a string).
word.matches("^[\\d,;]+$")
The Pattern documentation is pretty good : http://download.oracle.com/javase/1.5.0/docs/api/java/util/regex/Pattern.html
Also you can try your regexps online at: http://www.regexplanet.com/simple/index.html
There is a way to do this without explicitly setting your SHELL variable to point to bash. This can be useful if you have many makefiles since SHELL isn't inherited by subsequent makefiles or taken from the environment. You also need to be sure that anyone who compiles your code configures their system this way.
If you run sudo dpkg-reconfigure dash
and answer 'no' to the prompt, your system will not use dash as the default shell. It will then point to bash (at least in Ubuntu). Note that using dash as your system shell is a bit more efficient though.
It depends on the Markdown rendering engine and the Markdown flavour. There is no standard for this. If you mean GitHub flavoured Markdown for example, shell
should work fine. Aliases are sh
, bash
or zsh
. You can find the list of available syntax lexers here.
I wouldn't reference the parent directly in the child objects. In my opinion the childs shouldn't know anything about the parents. This will limits the flexibility!
I would solve this with events/handlers.
public class Meter
{
private int _powerRating = 0;
private Production _production;
public Meter()
{
_production = new Production();
_production.OnRequestPowerRating += new Func<int>(delegate { return _powerRating; });
_production.DoSomething();
}
}
public class Production
{
protected int RequestPowerRating()
{
if (OnRequestPowerRating == null)
throw new Exception("OnRequestPowerRating handler is not assigned");
return OnRequestPowerRating();
}
public void DoSomething()
{
int powerRating = RequestPowerRating();
Debug.WriteLine("The parents powerrating is :" + powerRating);
}
public Func<int> OnRequestPowerRating;
}
In this case I solved it with the Func<> generic, but can be done with 'normal' functions. This why the child(Production) is totally independent from it's parent(Meter).
But! If there are too many events/handlers or you just want to pass a parent object, i would solve it with an interface:
public interface IMeter
{
int PowerRating { get; }
}
public class Meter : IMeter
{
private int _powerRating = 0;
private Production _production;
public Meter()
{
_production = new Production(this);
_production.DoSomething();
}
public int PowerRating { get { return _powerRating; } }
}
public class Production
{
private IMeter _meter;
public Production(IMeter meter)
{
_meter = meter;
}
public void DoSomething()
{
Debug.WriteLine("The parents powerrating is :" + _meter.PowerRating);
}
}
This looks pretty much the same as the solution mentions, but the interface could be defined in another assembly and can be implemented by more than 1 class.

I figured it out. It's:
DBCC CHECKIDENT ('tablename', RESEED, newseed)
They are different functions. You should decide for your situation what do you need.
I don't consider using any of them as a bad practice. Most of the time IsNullOrEmpty()
is enough. But you have the choice :)

You should always pay attention to types.
Although they all seem like strings, "Hello"
and ",world"
are literals.
And in your example, exclam
is a std::string
object.
C++ has an operator overload that takes a std::string
object and adds another string to it. When you concatenate a std::string
object with a literal it will make the appropriate casting for the literal.
But if you try to concatenate two literals, the compiler won't be able to find an operator that takes two literals.
If your form does not have any id, but it has a class name like theForm, you can use the below statement to submit it:
document.getElementsByClassName("theForm")[0].submit();
I was having the same problem. This worked for me:
.center {
margin: 0 auto;
width: 400px;
**display:block**
}
I can recommend the EnhCommentify plugin.
eg. put this to your vimrc:
let maplocalleader=','
vmap <silent> <LocalLeader>c <Plug>VisualTraditional
nmap <silent> <LocalLeader>c <Plug>Traditional
let g:EnhCommentifyBindInInsert = 'No'
let g:EnhCommentifyMultiPartBlocks = 'Yes'
let g:EnhCommentifyPretty = 'Yes'
let g:EnhCommentifyRespectIndent = 'Yes'
let g:EnhCommentifyUseBlockIndent = 'Yes'
you can then comment/uncomment the (selected) lines with ',c'
To sort by a property in the object, you have to specify a comparer or a method to get that property.
Using the List.Sort
method:
theList.Sort(Function(x, y) x.age.CompareTo(y.age))
Using the OrderBy
extension method:
theList = theList.OrderBy(Function(x) x.age).ToList()
Tested and working in Angular 9.0
If you're getting the data using API
array: [];
ngOnInit() {
this.service.method()
.subscribe(
data=>
{
this.array = JSON.parse(JSON.stringify(data.object));
}
)
}
You can use that array to print your results from API data in html template.
Like
<p>{{array['something']}}</p>
Outdated answer. Please use
dplyr::sample_frac()
ordplyr::sample_n()
instead.
In my R package there is a function sample.rows
just for this purpose:
install.packages('kimisc')
library(kimisc)
example(sample.rows)
smpl..> set.seed(42)
smpl..> sample.rows(data.frame(a=c(1,2,3), b=c(4,5,6),
row.names=c('a', 'b', 'c')), 10, replace=TRUE)
a b
c 3 6
c.1 3 6
a 1 4
c.2 3 6
b 2 5
b.1 2 5
c.3 3 6
a.1 1 4
b.2 2 5
c.4 3 6
Enhancing sample
by making it a generic S3 function was a bad idea, according to comments by Joris Meys to a previous answer.
try this:
i=new Array("aaaa", "bbbb");
j=new Array("cccc", "dddd");
i=i.concat(j);
In short:
someValues.forEach((element) => {
console.log(element);
});
If you care about index, then second parameter can be passed to receive the index of current element:
someValues.forEach((element, index) => {
console.log(`Current index: ${index}`);
console.log(element);
});
Refer here to know more about Array of ES6: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array
It works:
Bitmap bitmap = BitmapFactory.decodeFile(filePath);
Yes, you can enforce the constraint only when the value is not NULL. This can be easily tested with the following example:
CREATE DATABASE t;
USE t;
CREATE TABLE parent (id INT NOT NULL,
PRIMARY KEY (id)
) ENGINE=INNODB;
CREATE TABLE child (id INT NULL,
parent_id INT NULL,
FOREIGN KEY (parent_id) REFERENCES parent(id)
) ENGINE=INNODB;
INSERT INTO child (id, parent_id) VALUES (1, NULL);
-- Query OK, 1 row affected (0.01 sec)
INSERT INTO child (id, parent_id) VALUES (2, 1);
-- ERROR 1452 (23000): Cannot add or update a child row: a foreign key
-- constraint fails (`t/child`, CONSTRAINT `child_ibfk_1` FOREIGN KEY
-- (`parent_id`) REFERENCES `parent` (`id`))
The first insert will pass because we insert a NULL in the parent_id
. The second insert fails because of the foreign key constraint, since we tried to insert a value that does not exist in the parent
table.
The package name is used for unique identification for your application.
Android uses the package name to determine if the application has been installed or not.
The general naming is:
com.companyname.applicationname
eg:
com.android.Camera
There is no semicolon at the end of that instruction causing the error.
EDIT
Like RiverC pointed out, there is no semicolon at the end of the previous line!
require ("scripts/connect.php")
EDIT
It seems you have no-semicolons whatsoever.
http://php.net/manual/en/language.basic-syntax.instruction-separation.php
As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.
I'm using Json.net in my project and it works great. In you case, you can do this to parse your json:
EDIT: I changed the code so it supports reading your json file (array)
Code to parse:

var json = System.IO.File.ReadAllText(@"d:\test.json");
var objects = JArray.Parse(json); // parse as array

BTW, you can use LinqPad to test your code, easier than creating a solution or project in Visual Studio I think.
Files in your project are available to you relative to your src folder. if you know which package or folder myfile.txt will be in, say it is in
----src
--------package1
------------myfile.txt
------------Prog.java
you can specify its path as "src/package1/myfile.txt" from Prog.java
import datetime
import pytz
# datetime object with timezone awareness:
datetime.datetime.now(tz=pytz.utc)
# seconds from epoch:
datetime.datetime.now(tz=pytz.utc).timestamp()
# ms from epoch:
int(datetime.datetime.now(tz=pytz.utc).timestamp() * 1000)
Actually I think the LIMIT 10
would be issued to the database so slicing would not occur in Python but in the database.
See limiting-querysets for more information.
Use the ref
keyword.
Look at the definitive reference here to understand passing parameters.
To be specific, look at this, to understand the behavior of the code.
EDIT: Sort
works on the same reference (that is passed by value) and hence the values are ordered. However, assigning a new instance to the parameter won't work because parameter is passed by value, unless you put ref
.
Putting ref
lets you change the pointer to the reference to a new instance of List
in your case. Without ref
, you can work on the existing parameter, but can't make it point to something else.
You can write the where
clause as:
where (case when (:stateCode = '') then (1)
when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
else 0)
end) = 1;
Alternatively, remove the case
entirely:
where (:stateCode = '') or
((:stateCode != '') and vw.state_cd in (:stateCode));
Or, even better:
where (:stateCode = '') or vw.state_cd in (:stateCode)
If you are using LINUX, you can use pyALSAAUDIO. For windows, we have PyAudio and there is also a library called SoundAnalyse.
I found an example for Linux here:
#!/usr/bin/python
## This is an example of a simple sound capture script.
##
## The script opens an ALSA pcm for sound capture. Set
## various attributes of the capture, and reads in a loop,
## Then prints the volume.
##
## To test it out, run it and shout at your microphone:
import alsaaudio, time, audioop
# Open the device in nonblocking capture mode. The last argument could
# just as well have been zero for blocking mode. Then we could have
# left out the sleep call in the bottom of the loop
inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE,alsaaudio.PCM_NONBLOCK)
# Set attributes: Mono, 8000 Hz, 16 bit little endian samples
inp.setchannels(1)
inp.setrate(8000)
inp.setformat(alsaaudio.PCM_FORMAT_S16_LE)
# The period size controls the internal number of frames per period.
# The significance of this parameter is documented in the ALSA api.
# For our purposes, it is suficcient to know that reads from the device
# will return this many frames. Each frame being 2 bytes long.
# This means that the reads below will return either 320 bytes of data
# or 0 bytes of data. The latter is possible because we are in nonblocking
# mode.
inp.setperiodsize(160)
while True:
# Read data from device
l,data = inp.read()
if l:
# Return the maximum of the absolute value of all samples in a fragment.
print audioop.max(data, 2)
time.sleep(.001)
First, you'll need to tell git about yourself. Get your username and token together from your settings page.
Then run:
git config --global github.user YOUR_USERNAME
git config --global github.token YOURTOKEN
You will need to generate a new key if you don't have a back-up of your key.
Then you should be able to run:
git clone [email protected]:YOUR_USERNAME/YOUR_PROJECT.git
Just using Data Binding syntax. For example,
<Button x:Name="btn"
Content="Click"
Command="{Binding ClickCmd}"
CommandParameter="{Binding ElementName=btn,Path=Content}" />
Not only can we use Data Binding to get some data from View Models, but also pass data back to View Models. In CommandParameter, must use ElementName to declare binding source explicitly.
With the solutions already discussed above the most reliable one is using Browsermob-Proxy
But while working with the remote grid machine, Browsermob-proxy isn't really helpful.
This is how I fixed the problem in my case. Hopefully, might be helpful for anyone with a similar setup.

The lifecycle of a servlet is controlled by the container in which the servlet has been deployed. When a request is mapped to a servlet, the container performs the following steps.
If an instance of the servlet does not exist, the web container:
a. Loads the servlet class
b. Creates an instance of the servlet class
c. Initializes the servlet instance by calling the init method (initialization is covered in Creating and Initializing a Servlet)
The container invokes the service method, passing request and response objects. Service methods are discussed in Writing Service Methods.
A 0 value on load-on-startup
means that point 1 is executed when a request comes to that servlet. Other values means that point 1 is executed at container startup.

Just to add to Joe Kington's answer (not enough reputation for a comment) there is a good example of mixing 2d and 3d plots in the documentation at http://matplotlib.org/examples/mplot3d/mixed_subplots_demo.html which shows projection='3d' working in combination with the Axes3D import.
from mpl_toolkits.mplot3d import Axes3D
...
ax = fig.add_subplot(2, 1, 1)
...
ax = fig.add_subplot(2, 1, 2, projection='3d')
In fact as long as the Axes3D import is present the line
from mpl_toolkits.mplot3d import Axes3D
...
ax = fig.gca(projection='3d')
as used by the OP also works. (checked with matplotlib version 1.3.1)
For ASP.NET Core You can use asp-route-* attribute:
<form asp-action="Login" asp-route-previous="@Model.ReturnUrl">
An example: Imagine that you have a Vehicle Controller with actions
Index
Details
Edit
and you can edit any vehicle from Index or from Details, so if you clicked edit from index you must return to index after edit and if you clicked edit from details you must return to details after edit.
//In your viewmodel add the ReturnUrl Property
public class VehicleViewModel
{
..............
..............
public string ReturnUrl {get;set;}
}
Details.cshtml
<a asp-action="Edit" asp-route-previous="Details" asp-route-id="@Model.CarId">Edit</a>
Index.cshtml
<a asp-action="Edit" asp-route-previous="Index" asp-route-id="@item.CarId">Edit</a>
Edit.cshtml
<form asp-action="Edit" asp-route-previous="@Model.ReturnUrl" class="form-horizontal">
<div class="box-footer">
<a asp-action="@Model.ReturnUrl" class="btn btn-default">Back to List</a>
<button type="submit" value="Save" class="btn btn-warning pull-right">Save</button>
</div>
</form>
In your controller:
// GET: Vehicle/Edit/5
public ActionResult Edit(int id,string previous)
{
var model = this.UnitOfWork.CarsRepository.GetAllByCarId(id).FirstOrDefault();
var viewModel = this.Mapper.Map<VehicleViewModel>(model);//if you using automapper
//or by this code if you are not use automapper
var viewModel = new VehicleViewModel();
if (!string.IsNullOrWhiteSpace(previous)
viewModel.ReturnUrl = previous;
else
viewModel.ReturnUrl = "Index";
return View(viewModel);
}
[HttpPost]
public IActionResult Edit(VehicleViewModel model, string previous)
{
if (!string.IsNullOrWhiteSpace(previous))
model.ReturnUrl = previous;
else
model.ReturnUrl = "Index";
.............
.............
return RedirectToAction(model.ReturnUrl);

This property controls the magnification level for the current element. The rendering effect for the element is that of a “zoom” function on a camera. Even though this property is not inherited, it still affects the rendering of child elements.
Example
div { zoom: 200% }
<div style=”zoom: 200%”>This is x2 text </div>
i think Access is a best choice for your case. But you have to split database, see: http://accessblog.net/2005/07/how-to-split-database-into-be-and-fe.html
•How can we make sure that the write-user can make changes to the table data while other users use the data? Do the read-users put locks on tables? Does the write-user have to put locks on the table? Does Access do this for us or do we have to explicitly code this?
there are no read locks unless you put them explicitly. Just use "No Locks"
•Are there any common problems with "MS Access transactions" that we should be aware of?
should not be problems with 1-2 write users
•Can we work on forms, queries etc. while they are being used? How can we "program" without being in the way of the users?
if you split database - then no problem to work on FE design.
•Which settings in MS Access have an influence on how things are handled?
What do you mean?
•Our background is mostly in Oracle, where is Access different in handling multiple users? Is there such thing as "isolation levels" in Access?
no isolation levels in access. BTW, you can then later move data to oracle and keep access frontend, if you have lot of users and big database.
Instead of triggering builds remotely, change your Jenkins project configuration to trigger builds by polling.
Jenkins can poll based on a fixed internal, or by a URL. The latter is what you want to skip builds if there are not changes for that branch. The exact details are in the documentation. Essentially you just need to check the "Poll SCM" option, leave the schedule section blank, and set a remote URL to hit JENKINS_URL/job/name/polling.
One gotcha if you have a secured Jenkins environment is unlike /build
, the /polling
URL requires authentication. The instructions here have details. For example, I have a GitHub Post-Receive hook going to username:apiToken@JENKIS_URL/job/name/polling
.
I have 2 CSV files that I use to read data. The java program is exported as a runnable jar file. When you export it, you will figure out it doesn't export your resources with it.
I added a folder under project called data in eclipse. In that folder i stored my csv files.
When I need to reference those files I do it like this...
private static final String ZIP_FILE_LOCATION_PRIMARY = "free-zipcode-database-Primary.csv";
private static final String ZIP_FILE_LOCATION = "free-zipcode-database.csv";
private static String getFileLocation(){
String loc = new File("").getAbsolutePath() + File.separatorChar +
"data" + File.separatorChar;
if (usePrimaryZipCodesOnly()){
loc = loc.concat(ZIP_FILE_LOCATION_PRIMARY);
} else {
loc = loc.concat(ZIP_FILE_LOCATION);
}
return loc;
}
Then when you put the jar in a location so it can be ran via commandline, make sure that you add the data folder with the resources into the same location as the jar file.
if (window.sidebar) { // Mozilla Firefox Bookmark
window.sidebar.addPanel(document.title,location.href,"");
It adds the bookmark but in the sidebar.
In C++ (STL) there is a pair class for bundling two objects. In Java Generics a pair class isn't available, although there is some demand for it. You could easily implement it yourself though.
I agree however with some other answers that if you need to return two or more objects from a method, it would be better to encapsulate them in a class.

You should grab the standard input of the su
process just launched and write down the command there, otherwise you are running the commands with the current UID
.
Try something like this:
try{
Process su = Runtime.getRuntime().exec("su");
DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());
outputStream.writeBytes("screenrecord --time-limit 10 /sdcard/MyVideo.mp4\n");
outputStream.flush();
outputStream.writeBytes("exit\n");
outputStream.flush();
su.waitFor();
}catch(IOException e){
throw new Exception(e);
}catch(InterruptedException e){
throw new Exception(e);
}
CopyOnWriteArrayList
Use CopyOnWriteArrayList
class. This is the thread safe version of ArrayList
.
Only slightly related to the question, but try to wrap your head around this one. So un-intuitive:
import java.nio.file.*;
class Main {
public static void main(String[] args) {
Path p1 = Paths.get("/personal/./photos/./readme.txt");
Path p2 = Paths.get("/personal/index.html");
Path p3 = p1.relativize(p2);
System.out.println(p3); //prints ../../../../index.html !!
}
}
An explanation is given here:
So if your program is using math functions and including
math.h
, then you need to explicitly link the math library by passing the-lm
flag. The reason for this particular separation is that mathematicians are very picky about the way their math is being computed and they may want to use their own implementation of the math functions instead of the standard implementation. If the math functions were lumped intolibc.a
it wouldn't be possible to do that.
[Edit]
I'm not sure I agree with this, though. If you have a library which provides, say, sqrt()
, and you pass it before the standard library, a Unix linker will take your version, right?
I would simply use,
np.asarray(input, dtype=np.float)[0]
input
is an ndarray
of the right dtype, there is no overhead, since np.asarray
does nothing in this case.input
is a list
, np.asarray
makes sure the output is of the right type.To change JDK's version, you can do:
1- Project > Properties
2- Go to Java Build Path
3- In Libraries, select JRE System ... and click on Edit
4- Choose your appropriate version and validate

From C#3.5 I assume you're using WPF.
Just make a two-way data binding from an integer property to your text-box. WPF will show the validation error for you automatically.
For the email case, make a two-way data binding from a string property that does Regexp validation in the setter and throw an Exception upon validation error.

You can calculate the checksum of a file by reading the binary data and using hashlib.md5().hexdigest()
. A function to do this would look like the following:
def File_Checksum_Dis(dirname):
if not os.path.exists(dirname):
print(dirname+" directory is not existing");
for fname in os.listdir(dirname):
if not fname.endswith('~'):
fnaav = os.path.join(dirname, fname);
fd = open(fnaav, 'rb');
data = fd.read();
fd.close();
print("-"*70);
print("File Name is: ",fname);
print(hashlib.md5(data).hexdigest())
print("-"*70);

The below regex would match white spaces but not of a new line character.
(?:(?!\n)\s)
If you want to add carriage return also then add \r
with the |
operator inside the negative lookahead.
(?:(?![\n\r])\s)
Add +
after the non-capturing group to match one or more white spaces.
(?:(?![\n\r])\s)+
I don't know why you people failed to mention the POSIX character class [[:blank:]]
which matches any horizontal whitespaces (spaces and tabs). This POSIX chracter class would work on BRE(Basic REgular Expressions), ERE(Extended Regular Expression), PCRE(Perl Compatible Regular Expression).
You can take using the following method

Results of trying the provided solutions:
I tried all the settings as provided above but I was unable to resolve the issue
Explanation regarding the issue:
As per my observation DevToolsActivePort file doesn't exist is caused when chrome is unable to find its reference in scoped_dirXXXXX folder.
Steps taken to solve the issue
Added the below code to invoke the chrome
System.setProperty("webdriver.chrome.driver","pathto\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(options);
driver.get(url);
Using the above steps I was able to resolve the issue.
Thanks for your answers.
The python function returning just the package version in a machine-readable format:
from importlib.metadata import version
version('numpy')
Prior to python 3.8:
pip install importlib-metadata
from importlib_metadata import version
version('numpy')
The bash equivalent (here also invoked from python) would be much more complex (but more robust - see caution below):
import subprocess
def get_installed_ver(pkg_name):
bash_str="pip freeze | grep -w %s= | awk -F '==' {'print $2'} | tr -d '\n'" %(pkg_name)
return(subprocess.check_output(bash_str, shell=True).decode())
Sample usage:
# pkg_name="xgboost"
# pkg_name="Flask"
# pkg_name="Flask-Caching"
pkg_name="scikit-learn"
print(get_installed_ver(pkg_name))
>>> 0.22
Note that in both cases pkg_name
parameter should contain package name in the format as returned by pip freeze
and not as used during import
, e.g. scikit-learn
not sklearn
or Flask-Caching
, not flask_caching
.
Note that while invoking pip freeze
in bash version may seem inefficient, only this method proves to be sufficiently robust to package naming peculiarities and inconsistencies (e.g. underscores vs dashes, small vs large caps, and abbreviations such as sklearn
vs scikit-learn
).
Caution: in complex environments both variants can return surprise version numbers, inconsistent with what you can actually get during import
.
One such problem arises when there are other versions of the package hidden in a user site-packages
subfolder. As an illustration of the perils of using version()
here's a situation I encountered:
$ pip freeze | grep lightgbm
lightgbm==2.3.1
and
$ python -c "import lightgbm; print(lightgbm.__version__)"
2.3.1
vs.
$ python -c "from importlib_metadata import version; print(version(\"lightgbm\"))"
2.2.3
until you delete the subfolder with the old version (here 2.2.3) from the user folder (only one would normally be preserved by `pip` - the one installed as last with the `--user` switch):
$ ls /home/jovyan/.local/lib/python3.7/site-packages/lightgbm*
/home/jovyan/.local/lib/python3.7/site-packages/lightgbm-2.2.3.dist-info
/home/jovyan/.local/lib/python3.7/site-packages/lightgbm-2.3.1.dist-info
Another problem is having some conda-installed packages in the same environment. If they share dependencies with your pip-installed packages, and versions of these dependencies differ, you may get downgrades of your pip-installed dependencies.
To illustrate, the latest version of numpy
available in PyPI on 04-01-2020 was 1.18.0, while at the same time Anaconda's conda-forge
channel had only 1.17.3 version on numpy
as their latest. So when you installed a basemap
package with conda (as second), your previously pip-installed numpy
would get downgraded by conda to 1.17.3, and version 1.18.0 would become unavailable to the import
function. In this case version()
would be right, and pip freeze
/conda list
wrong:
$ python -c "from importlib_metadata import version; print(version(\"numpy\"))"
1.17.3
$ python -c "import numpy; print(numpy.__version__)"
1.17.3
$ pip freeze | grep numpy
numpy==1.18.0
$ conda list | grep numpy
numpy 1.18.0 pypi_0 pypi
In my experience switching branches in the superproject or future checkouts will still cause detached HEADs of submodules regardless if the submodule is properly added and tracked (i.e. @djacobs7 and @Johnny Z answers).
And instead of manually checking out the correct branch manually or through a script git submodule foreach can be used.
This will check the submodule config file for the branch property and checkout the set branch.
git submodule foreach -q --recursive 'branch="$(git config -f <path>.gitmodules submodule.$name.branch)"; git checkout $branch'
If your test coverage is good on all the public method inside the tested class, the privates methods called by the public one will be automatically tested since you will assert all the possible case.
The JUnit Doc says:
Testing private methods may be an indication that those methods should be moved into another class to promote reusability. But if you must... If you are using JDK 1.3 or higher, you can use reflection to subvert the access control mechanism with the aid of the PrivilegedAccessor. For details on how to use it, read this article.
Packaging of pom
is used in projects that aggregate other projects, and in projects whose only useful output is an attached artifact from some plugin. In your case, I'd guess that your top-level pom includes <modules>...</modules>
to aggregate other directories, and the actual output is the result of one of the other (probably sub-) directories. It will, if coded sensibly for this purpose, have a packaging of war
.
You can use the reset()
method:
$('#myform')[0].reset();
or without jQuery:
document.getElementById('myform').reset();
where myform
is the id of the form containing the elements you want to be cleared.
You could also use the :input
selector if the fields are not inside a form:
$(':input').val('');
Bind a change
handler, then just uncheck all of the checkboxes, apart from the one checked:
$('input.example').on('change', function() {
$('input.example').not(this).prop('checked', false);
});
you can put this tag into your html.
<button class='btn btn-primary' onfocus='this.blur'>
Button Text
</button>
I used on focus because onclick still displayed the glow for a microsecond and made a horrible looking flash in terms of using it. This seemed to get rid after all the css methods failed.
Josh David Miller is correct.
PCoelho, In case you're wondering what $compile
does behind the scenes and how HTML output is generated from the directive, please take a look below
The $compile
service compiles the fragment of HTML("< test text='n' >< / test >"
) that includes the directive("test" as an element) and produces a function. This function can then be executed with a scope to get the "HTML output from a directive".
var compileFunction = $compile("< test text='n' > < / test >");
var HtmlOutputFromDirective = compileFunction($scope);
More details with full code samples here: http://www.learn-angularjs-apps-projects.com/AngularJs/dynamically-add-directives-in-angularjs
you can use the following line of code as well
per_page = parseInt(req.query.per_page) || 10
page_no = parseInt(req.query.page_no) || 1
var pagination = {
limit: per_page ,
skip:per_page * (page_no - 1)
}
users = await User.find({<CONDITION>}).limit(pagination.limit).skip(pagination.skip).exec()
this code will work in latest version of mongo
I don't think there are any machine code decompilers that produce Pascal code. Most "Delphi decompilers" parse form and RTTI data, but do not actually decompile the machine code. I can only recommend using something like DeDe (or similar software) to extract symbol information in combination with a C decompiler, then translate the decompiled C code to Delphi (there are many source code converters out there).
I'm using cocoapods version 1.0.1

Improving upon Prajeet Shrestha answer : -
You can make a generic extension for NSMutableAttributedString which involves less code. In this case I have chosen to use system font but you could adapt it so you can input the font name as a parameter.
extension NSMutableAttributedString {
func systemFontWith(text: String, size: CGFloat, weight: CGFloat) -> NSMutableAttributedString {
let attributes: [String: AnyObject] = [NSFontAttributeName: UIFont.systemFont(ofSize: size, weight: weight)]
let string = NSMutableAttributedString(string: text, attributes: attributes)
self.append(string)
return self
}
}
Ion_auth! Looks very promising and small footprint! I like..
It's been more than 6 years since the question was asked, but I didn't find any tool to clean up my repository. So I wrote one myself in python to get rid of old jars. Maybe it will be useful for someone:
from os.path import isdir
from os import listdir
import re
import shutil
dry_run = False # change to True to get a log of what will be removed
m2_path = '/home/jb/.m2/repository/' # here comes your repo path
version_regex = '^\d[.\d]*$'
def check_and_clean(path):
files = listdir(path)
for file in files:
if not isdir('/'.join([path, file])):
return
last = check_if_versions(files)
if last is None:
for file in files:
check_and_clean('/'.join([path, file]))
elif len(files) == 1:
return
else:
print('update ' + path.split(m2_path)[1])
for file in files:
if file == last:
continue
print(file + ' (newer version: ' + last + ')')
if not dry_run:
shutil.rmtree('/'.join([path, file]))
def check_if_versions(files):
if len(files) == 0:
return None
last = ''
for file in files:
if re.match(version_regex, file):
if last == '':
last = file
if len(last.split('.')) == len(file.split('.')):
for (current, new) in zip(last.split('.'), file.split('.')):
if int(new) > int(current):
last = file
break
elif int(new) < int(current):
break
else:
return None
else:
return None
return last
check_and_clean(m2_path)
It recursively searches within the .m2
repository and if it finds a catalog where different versions reside it removes all of them but the newest.
Say you have the following tree somewhere in your .m2 repo:
.
+-- antlr
+-- 2.7.2
¦ +-- antlr-2.7.2.jar
¦ +-- antlr-2.7.2.jar.sha1
¦ +-- antlr-2.7.2.pom
¦ +-- antlr-2.7.2.pom.sha1
¦ +-- _remote.repositories
+-- 2.7.7
+-- antlr-2.7.7.jar
+-- antlr-2.7.7.jar.sha1
+-- antlr-2.7.7.pom
+-- antlr-2.7.7.pom.sha1
+-- _remote.repositories
Then the script removes version 2.7.2 of antlr and what is left is:
.
+-- antlr
+-- 2.7.7
+-- antlr-2.7.7.jar
+-- antlr-2.7.7.jar.sha1
+-- antlr-2.7.7.pom
+-- antlr-2.7.7.pom.sha1
+-- _remote.repositories
If any old version, that you actively use, will be removed. It can easily be restored with maven (or other tools that manage dependencies).
You can get a log of what is going to be removed without actually removing it by setting dry_run = False
. The output will go like this:
update /org/projectlombok/lombok
1.18.2 (newer version: 1.18.6)
1.16.20 (newer version: 1.18.6)
This means, that versions 1.16.20 and 1.18.2 of lombok will be removed and 1.18.6 will be left untouched.
The file can be found on my github (the latest version).
