Just wanted to add something: I found tim cooper's answer very useful, I used it to make a method which accepts an array of positions and does the insert on all of them so here that is:
EDIT: Looks like my old function assumed $insertstr
was only 1 character and that the array was sorted. This works for arbitrary character length.
function stringInsert($str, $pos, $insertstr) {
if (!is_array($pos)) {
$pos = array($pos);
} else {
asort($pos);
}
$insertionLength = strlen($insertstr);
$offset = 0;
foreach ($pos as $p) {
$str = substr($str, 0, $p + $offset) . $insertstr . substr($str, $p + $offset);
$offset += $insertionLength;
}
return $str;
}
First you need to export HTTP_PROXY
. Second, you need to read man sudo
carefully, and pay attention to the -E
flag. This works:
$ export HTTP_PROXY=foof
$ sudo -E bash -c 'echo $HTTP_PROXY'
Here is the quote from the man page:
-E, --preserve-env
Indicates to the security policy that the user wishes to preserve their
existing environment variables. The security policy may return an error
if the user does not have permission to preserve the environment.
install exceljs
npm i exceljs --save
import exceljs
var Excel = require('exceljs');
var workbook = new Excel.Workbook();
create workbook
var options = {
filename: __dirname+'/Reports/'+reportName,
useStyles: true,
useSharedStrings: true
};
var workbook = new Excel.stream.xlsx.WorkbookWriter(options);
after create worksheet
var worksheet = workbook.addWorksheet('Rate Sheet',{properties:{tabColor:{argb:'FFC0000'}}});
in worksheet.column array you pass column name in header and array key pass in key
worksheet.columns = [
{ header: 'column name', key: 'array key', width: 35},
{ header: 'column name', key: 'array key', width: 35},
{ header: 'column name', key: 'array key', width: 20},
];
after using forEach loop append row one by one in exel file
array.forEach(function(row){ worksheet.addRow(row); })
you can also perfome loop on each exel row and cell
worksheet.eachRow(function(row, rowNumber) {
console.log('Row ' + rowNumber + ' = ' + JSON.stringify(row.values));
});
row.eachCell(function(cell, colNumber) {
console.log('Cell ' + colNumber + ' = ' + cell.value);
});
You can do it converting by the constructor to a string using .toString() :
function getObjectClass(obj){
if (typeof obj != "object" || obj === null) return false;
else return /(\w+)\(/.exec(obj.constructor.toString())[1];}
you may also check if:
{float: left;}
and
{clear: both;}
are used correctly in your css.
Use del /F /Q
to force deletion of read-only files (/F
) and directories and not ask to confirm (/Q
) when deleting via wildcard.
I found a very easy way to do this and it's what I'm using in my app.
Let's say you have the dates in Time objects (or whatever, we just need the milliseconds):
Time date1 = initializeDate1(); //get the date from somewhere
Time date2 = initializeDate2(); //get the date from somewhere
long millis1 = date1.toMillis(true);
long millis2 = date2.toMillis(true);
long difference = millis2 - millis1 ;
//now get the days from the difference and that's it
long days = TimeUnit.MILLISECONDS.toDays(difference);
//now you can do something like
if(days == 7)
{
//do whatever when there's a week of difference
}
if(days >= 30)
{
//do whatever when it's been a month or more
}
if your SQL query is this
SELECT id,name,roll FROM student WHERE name='Amit' AND roll='7'
then rawQuery will be
String query="SELECT id, name, roll FROM student WHERE name = ? AND roll = ?";
String[] selectionArgs = {"Amit","7"}
db.rawQuery(query, selectionArgs);
It's ok if you want to check validate dd/MM/yyyy
function isValidDate(date) {_x000D_
var temp = date.split('/');_x000D_
var d = new Date(temp[1] + '/' + temp[0] + '/' + temp[2]);_x000D_
return (d && (d.getMonth() + 1) == temp[1] && d.getDate() == Number(temp[0]) && d.getFullYear() == Number(temp[2]));_x000D_
}_x000D_
_x000D_
alert(isValidDate('29/02/2015')); // it not exist ---> false_x000D_
_x000D_
Use subprocess.Popen:
import subprocess
process = subprocess.Popen(['ls', '-a'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = process.communicate()
print(out)
Note that communicate blocks until the process terminates. You could use process.stdout.readline() if you need the output before it terminates. For more information see the documentation.
If you want to pass the cookie to the browser, you have to append to the headers to be sent back. If you're using wsgi:
import requests
...
def application(environ, start_response):
cookie = {'enwiki_session': '17ab96bd8ffbe8ca58a78657a918558'}
response_headers = [('Content-type', 'text/plain')]
response_headers.append(('Set-Cookie',cookie))
...
return [bytes(post_env),response_headers]
I'm successfully able to authenticate with Bugzilla and TWiki hosted on the same domain my python wsgi script is running by passing auth user/password to my python script and pass the cookies to the browser. This allows me to open the Bugzilla and TWiki pages in the same browser and be authenticated. I'm trying to do the same with SuiteCRM but i'm having trouble with SuiteCRM accepting the session cookies obtained from the python script even though it has successfully authenticated.
Comment by @Niagaradad helped me. I was entering the wrong password the whole time.
Notice the error message
ERROR 1045 (28000): Access denied for user 'ayaz'@'localhost' (using password: YES)
It says, Password: Yes. That means I am sending the password to SQL and that is wrong.
Usually root account doesn't have password if you haven't set one. If you have installed mysql via homebrew then root account won't have a password.
Here is the comment.
so, not exactly the same then. NO means you are not sending a password to MySQL. YES means you are sending a password to MySQL but the incorrect one. Did you specifically set a password for the mysql root user when you installed MySQL? By default there is no password so you can use mysql -u root -p and hit enter.
If it has a UI, it has an "API". Let's use the following example: I want to publish the pic I use in any new blog post I create. Let's assume is Wordpress.
In case you are using bundler, you need to add something like this to your Gemfile:
gem 'redcarpet', :git => 'git://github.com/tanoku/redcarpet.git'
And in case there is .gemspec
file, it should be able to fetch and install the gem when running bundle install
.
UPD. As indicated in comments, for Bundler to function properly you also need to add the following to config.ru
:
require "bundler"
Bundler.setup(:default)
You can Try this:
CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.removeAllCookie();
Intent intent= new Intent(YourCurrent.this, YourCurrent.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
You can run flutter clean
.
But that's most likely a problem with your IDE or similar, as flutter run creates a brand new apk. And hot reload push only modifications.
Try running your app using the command line flutter run
and then press r
or R
for respectively hot-reload and full-reload.
i faced this same, i check in in program and feature. there was an update has install for jdk1.8 which is not compatible with my old setting(jdk1.6.0) for ant in eclipse. I install that update. right now, my ant project is build success.
Try it, hope this will be helpful.
Letter lettre = Letter.values()[(int)(Math.random()*Letter.values().length)];
This lookup only features exact matches. If you have an extra space in one of the columns or something similar it will not recognize it.
This snipped worked for me (MySQL server 5.5) to kill all MySQL processes :
mysql -e "show full processlist;" -ss | awk '{print "KILL "$1";"}'| mysql
You can simply use DataColumnCollection.IndexOf
So that you can get the index of the required column by name then use it with your row:
row[dt.Columns.IndexOf("ColumnName")] = columnValue;
If your panel is 'not opaque' (transparent) you wont see your background color.
as has been already remarked, is used for the calling thread termination. After a call to that function a complicating clean up mechanism is started. When it completes the thread is terminated. The pthread_exit() API is also called implicitly when a call to the return() routine occurs in a thread created by pthread_create(). Actually, a call to return() and a call to pthread_exit() have the same impact, being called from a thread created by pthread_create().
It is very important to distinguish the initial thread, implicitly created when the main() function starts, and threads created by pthread_create(). A call to the return() routine from the main() function implicitly invokes the exit() system call and the entire process terminates. No thread clean up mechanism is started. A call to the pthread_exit() from the main() function causes the clean up mechanism to start and when it finishes its work the initial thread terminates.
What happens to the entire process (and to other threads) when pthread_exit() is called from the main() function depends on the PTHREAD implementation. For example, on IBM OS/400 implementation the entire process is terminated, including other threads, when pthread_exit() is called from the main() function. Other systems may behave differently. On most modern Linux machines a call to pthread_exit() from the initial thread does not terminate the entire process until all threads termination. Be careful using pthread_exit() from main(), if you want to write a portable application.
is a convenient way to wait for a thread termination. You may write your own function that waits for a thread termination, perhaps more suitable to your application, instead of using pthread_join(). For example, it can be a function based on waiting on conditional variables.
I would recommend for reading a book of David R. Butenhof “Programming with POSIX Threads”. It explains the discussed topics (and more complicated things) very well (although some implementation details, such as pthread_exit usage in the main function, not always reflected in the book).
Simply, row_num = df.shape[0] # gives number of rows, here's the example:
import pandas as pd
import numpy as np
In [322]: df = pd.DataFrame(np.random.randn(5,2), columns=["col_1", "col_2"])
In [323]: df
Out[323]:

I would simplify the most voted answer to:
BS="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
def to_base(n, b):
return "0" if not n else to_base(n//b, b).lstrip("0") + BS[n%b]
With the same advice for RuntimeError: maximum recursion depth exceeded in cmp
on very large integers and negative numbers. (You could usesys.setrecursionlimit(new_limit)
)
To avoid recursion problems:
BS="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
def to_base(s, b):
res = ""
while s:
res+=BS[s%b]
s//= b
return res[::-1] or "0"
Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.
Let me explain using step-by-step guidance.
First, download the source code from https://github.com/rmtheis/tess-two.
Import all three projects. After importing you will get an error.
To solve the error you have to create a res
folder in the tess-two project
First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"
After doing this in all three project the error should be gone.
Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.
Now you just need to import it into your workspace, but first you have to download android-ndk from this site:
http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file
Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable
Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture
done it
Now open cmd and go to on D:\Android Workspace\tess-two like below
If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:
Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest
Import test-two in this and run OCRTest and run it; you will get the best example of OCR.
The maintainability issue can be pretty easily overcome with a little formatting, like such:
let
my_var1 = 'foo',
my_var2 = 'bar',
my_var3 = 'baz'
;
I use this formatting strictly as a matter of personal preference. I skip this format for single declarations, of course, or where it simply gums up the works.
Mitch is right. It depends on resources (memory).
Although Raymond's article is dedicated to Windows threads, not to C# threads, the logic applies the same (C# threads are mapped to Windows threads).
However, as we are in C#, if we want to be completely precise, we need to distinguish between "started" and "non started" threads. Only started threads actually reserve stack space (as we could expect). Non started threads only allocate the information required by a thread object (you can use reflector if interested in the actual members).
You can actually test it for yourself, compare:
static void DummyCall()
{
Thread.Sleep(1000000000);
}
static void Main(string[] args)
{
int count = 0;
var threadList = new List<Thread>();
try
{
while (true)
{
Thread newThread = new Thread(new ThreadStart(DummyCall), 1024);
newThread.Start();
threadList.Add(newThread);
count++;
}
}
catch (Exception ex)
{
}
}
with:
static void DummyCall()
{
Thread.Sleep(1000000000);
}
static void Main(string[] args)
{
int count = 0;
var threadList = new List<Thread>();
try
{
while (true)
{
Thread newThread = new Thread(new ThreadStart(DummyCall), 1024);
threadList.Add(newThread);
count++;
}
}
catch (Exception ex)
{
}
}
Put a breakpoint in the exception (out of memory, of course) in VS to see the value of counter. There is a very significant difference, of course.
Based on @Peter Baley answer, I created a more generic function:
@objectId: HTML object ID
@values: can be a string or an array. String is less "secure" (should not contain repeated value).
function checkMultiValues(objectId, values){
selectMultiObject=document.getElementById(objectId);
for ( var i = 0, l = selectMultiObject.options.length, o; i < l; i++ )
{
o = selectMultiObject.options[i];
if ( values.indexOf( o.value ) != -1 )
{
o.selected = true;
} else {
o.selected = false;
}
}
}
Example: checkMultiValues('thisMultiHTMLObject','a,b,c,d');
A simple git fetch/pull command will throw a authentication failed message. But do the same git fetch/pull command second time, and it should prompt a window asking for credential(username/password). Enter your Id and new password and it should save and move on.
A different point is that the first sentence is parsed as:
scala> List(1,2,3).++(List(4,5))
res0: List[Int] = List(1, 2, 3, 4, 5)
Whereas the second example is parsed as:
scala> List(4,5).:::(List(1,2,3))
res1: List[Int] = List(1, 2, 3, 4, 5)
So if you are using macros, you should take care.
Besides, ++
for two lists is calling :::
but with more overhead because it is asking for an implicit value to have a builder from List to List. But microbenchmarks did not prove anything useful in that sense, I guess that the compiler optimizes such calls.
Micro-Benchmarks after warming up.
scala>def time(a: => Unit): Long = { val t = System.currentTimeMillis; a; System.currentTimeMillis - t}
scala>def average(a: () => Long) = (for(i<-1 to 100) yield a()).sum/100
scala>average (() => time { (List[Int]() /: (1 to 1000)) { case (l, e) => l ++ List(e) } })
res1: Long = 46
scala>average (() => time { (List[Int]() /: (1 to 1000)) { case (l, e) => l ::: List(e ) } })
res2: Long = 46
As Daniel C. Sobrai said, you can append the content of any collection to a list using ++
, whereas with :::
you can only concatenate lists.
I thought I'd share, or give back to the community ... It's ASCII based, and the solution is not perfect but it works quite well. Enjoy, Goran B.

As noted in comments above, while still on some UA implementations, readAsBinaryString
method didn't made its way to the specs and should not be used in production.
Instead, use readAsArrayBuffer
and loop through it's buffer
to get back the binary string :
document.querySelector('input').addEventListener('change', function() {_x000D_
_x000D_
var reader = new FileReader();_x000D_
reader.onload = function() {_x000D_
_x000D_
var arrayBuffer = this.result,_x000D_
array = new Uint8Array(arrayBuffer),_x000D_
binaryString = String.fromCharCode.apply(null, array);_x000D_
_x000D_
console.log(binaryString);_x000D_
_x000D_
}_x000D_
reader.readAsArrayBuffer(this.files[0]);_x000D_
_x000D_
}, false);
_x000D_
<input type="file" />_x000D_
<div id="result"></div>
_x000D_
For a more robust way to convert your arrayBuffer in binary string, you can refer to this answer.
Yes, the file API does provide a way to convert your File, in the <input type="file"/>
to a binary string, thanks to the FileReader Object and its method readAsBinaryString
.
[But don't use it in production !]
document.querySelector('input').addEventListener('change', function(){_x000D_
var reader = new FileReader();_x000D_
reader.onload = function(){_x000D_
var binaryString = this.result;_x000D_
document.querySelector('#result').innerHTML = binaryString;_x000D_
}_x000D_
reader.readAsBinaryString(this.files[0]);_x000D_
}, false);
_x000D_
<input type="file"/>_x000D_
<div id="result"></div>
_x000D_
If you want an array buffer, then you can use the readAsArrayBuffer()
method :
document.querySelector('input').addEventListener('change', function(){_x000D_
var reader = new FileReader();_x000D_
reader.onload = function(){_x000D_
var arrayBuffer = this.result;_x000D_
console.log(arrayBuffer);_x000D_
document.querySelector('#result').innerHTML = arrayBuffer + ' '+arrayBuffer.byteLength;_x000D_
}_x000D_
reader.readAsArrayBuffer(this.files[0]);_x000D_
}, false);
_x000D_
<input type="file"/>_x000D_
<div id="result"></div>
_x000D_
you can use
^[\w.-]+$
the +
is to make sure it has at least 1 character. Need the ^
and $
to denote the begin and end, otherwise if the string has a match in the middle, such as @@@@xyz%%%%
then it is still a match.
\w
already includes alphabets (upper and lower case), numbers, and underscore. So the rest .
, -
, are just put into the "class" to match. The +
means 1 occurrence or more.
P.S. thanks for the note in the comment
There are two ways to tackle dynamic csv lists for TSQL queries:
1) Using an inner select
SELECT * FROM myTable WHERE myColumn in (SELECT id FROM myIdTable WHERE id > 10)
2) Using dynamically concatenated TSQL
DECLARE @sql varchar(max)
declare @list varchar(256)
select @list = '1,2,3'
SELECT @sql = 'SELECT * FROM myTable WHERE myColumn in (' + @list + ')'
exec sp_executeSQL @sql
3) A possible third option is table variables. If you have SQl Server 2005 you can use a table variable. If your on Sql Server 2008 you can even pass whole table variables in as a parameter to stored procedures and use it in a join or as a subselect in the IN clause.
DECLARE @list TABLE (Id INT)
INSERT INTO @list(Id)
SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4
SELECT
*
FROM
myTable
JOIN @list l ON myTable.myColumn = l.Id
SELECT
*
FROM
myTable
WHERE
myColumn IN (SELECT Id FROM @list)
Create your own BaseAdapter class and use it as following.
public class NotificationScreen extends Activity
{
@Override
protected void onCreate_Impl(Bundle savedInstanceState)
{
setContentView(R.layout.notification_screen);
ListView notificationList = (ListView) findViewById(R.id.notification_list);
NotiFicationListAdapter notiFicationListAdapter = new NotiFicationListAdapter();
notificationList.setAdapter(notiFicationListAdapter);
homeButton = (Button) findViewById(R.id.home_button);
}
}
Make your own BaseAdapter class and its separate xml file.
public class NotiFicationListAdapter extends BaseAdapter
{
private ArrayList<HashMap<String, String>> data;
private LayoutInflater inflater=null;
public NotiFicationListAdapter(ArrayList data)
{
this.data=data;
inflater =(LayoutInflater)baseActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount()
{
return data.size();
}
public Object getItem(int position)
{
return position;
}
public long getItemId(int position)
{
return position;
}
public View getView(int position, View convertView, ViewGroup parent)
{
View vi=convertView;
if(convertView==null)
vi = inflater.inflate(R.layout.notification_list_item, null);
ImageView compleatImageView=(ImageView)vi.findViewById(R.id.complet_image);

TextView notification_message = (TextView)vi.findViewById(R.id.notification_message); // notification message
compleatImageView.setBackgroundResource(R.id.address_book);
name.setText(data.getIndex(position));
email_id.setText(data.getIndex(position));

The answer is no, but for me I did the following
the script: myExport
#! \bin\bash
export $1
an alias in my .bashrc
alias myExport='source myExport'
Still you source it, but maybe in this way it is more useable and it is interesting for someone else.
On my Macintosh systems, I find that "Adobe Reader" does a reasonably good job. I created an alias on my Desktop that points to the "Adobe Reader.app", and all I do is drop a pdf-file on the alias, which makes it the active document in Adobe Reader, and then from the File-menu, I choose "Save as Text...", give it a name and where to save it, click "Save", and I'm done.
You'll have to traverse by hand.
var aTags = document.getElementsByTagName("a");
var searchText = "SearchingText";
var found;
for (var i = 0; i < aTags.length; i++) {
if (aTags[i].textContent == searchText) {
found = aTags[i];
break;
}
}
// Use `found`.
its just simple
select * from myTable where year(columnX) = 2010
I haven't done this, so I'm just going to point at the right answer.
C has provisions for functions that take unspecified numbers of operands, using the <stdarg.h>
header. You can define your function as void log_out(const char *fmt, ...);
, and get the va_list
inside the function. Then you can allocate memory and call vsprintf()
with the allocated memory, format, and va_list
.
Alternately, you could use this to write a function analogous to sprintf()
that would allocate memory and return the formatted string, generating it more or less as above. It would be a memory leak, but if you're just logging out it may not matter.
Numpy provides two identical methods to do this. Either use
np.round(data, 2)
or
np.around(data, 2)
as they are equivalent.
See the documentation for more information.
Examples:
>>> import numpy as np
>>> a = np.array([0.015, 0.235, 0.112])
>>> np.round(a, 2)
array([0.02, 0.24, 0.11])
>>> np.around(a, 2)
array([0.02, 0.24, 0.11])
>>> np.round(a, 1)
array([0. , 0.2, 0.1])
If the remainder when you divide by 2 is 0, it's even. %
is the operator to get a remainder.
document.getElementById('mybox').style.display = "block";
To redirect output for all prints, you can do this:
import sys
with open('c:\\goat.txt', 'w') as f:
sys.stdout = f
print "test"
while 1:
root.update()
... is (very!) roughly similar to:
root.mainloop()
The difference is, mainloop
is the correct way to code and the infinite loop is subtly incorrect. I suspect, though, that the vast majority of the time, either will work. It's just that mainloop
is a much cleaner solution. After all, calling mainloop
is essentially this under the covers:
while the_window_has_not_been_destroyed():
wait_until_the_event_queue_is_not_empty()
event = event_queue.pop()
event.handle()
... which, as you can see, isn't much different than your own while loop. So, why create your own infinite loop when tkinter already has one you can use?
Put in the simplest terms possible: always call mainloop
as the last logical line of code in your program. That's how Tkinter was designed to be used.
Heh, there are some pretty exciting uses of ternary syntax in your question; I like the last one the best...
x = (1 < 2) ? true : false;
The use of ternary here is totally unnecessary - you could simply write
x = (1 < 2);
Likewise, the condition element of a ternary statement is always evaluated as a Boolean value, and therefore you can express:
(IsChecked == true) ? removeItem($this) : addItem($this);
Simply as:
(IsChecked) ? removeItem($this) : addItem($this);
In fact, I would also remove the IsChecked
temporary as well which leaves you with:
($this.hasClass("IsChecked")) ? removeItem($this) : addItem($this);
As for whether this is acceptable syntax, it sure is! It's a great way to reduce four lines of code into one without impacting readability. The only word of advice I would give you is to avoid nesting multiple ternary statements on the same line (that way lies madness!)
All the above answers are of good quality,but this one's just to memorize.The name Mutex is derived from Mutually Exclusive hence you are motivated to think of a mutex lock as Mutual Exclusion between two as in only one at a time,and if I possessed it you can have it only after I release it.On the other hand such case doesn't exist for Semaphore is just like a traffic signal(which the word Semaphore also means).
Use Simply this line code, there is no need to put anything in href attribute:

There's an excellent writeup of setting up a FreeBSD machine to do just this - take your standard old desktop, toss in an additional NIC, and build.
The writeup is available at http://www.freebsd.org/doc/en/articles/filtering-bridges/article.html.
In step 5 of the above instructions, you're enabling a firewall. For just simulating a different IP connection, you could (for example) do the following:
Create a file /etc/rc.firewall.56k
which contains the following:
ipfw add pipe 1 ip from any to any out
ipfw add pipe 2 ip from any to any in
ipfw pipe 1 config bw 56Kbit/s
ipfw pipe 2 config bw 56Kbit/s
And change /etc/rc.conf
... replace the line
firewall_type="open"
with
firewall_type="/etc/rc.firewall.56k"
reboot, and you've got yourself a 56K bridge!
If you happen to be working from a Macintosh, that OS has ipfw built into it by default. I've done the same thing by routing network traffic over the Airport and through the ethernet, setting it up so that anything coming over the airport has the same characteristics as whatever I'm trying to emulate. You can invoke the ipfw commands directly from the terminal and get the same effects.
You can't have duplicated keys in a dictionary. Use a dict of lists:
for line in data_list:
regNumber = line[0]
name = line[1]
phoneExtn = line[2]
carpark = line[3].strip()
details = (name,phoneExtn,carpark)
if not data_dict.has_key(regNumber):
data_dict[regNumber] = [details]
else:
data_dict[regNumber].append(details)

Gradle is a build tool custom and used for building APK or known as application package kit.
You need to do two things:
The code:
dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))
library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
geom_ribbon(alpha = 0.35, linetype=0)+
geom_line(aes(linetype=model), size = 1) +
geom_point(aes(shape=model), size=4) +
theme(legend.position=c(.6,0.8)) +
theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
scale_linetype_discrete("Model 1") +
scale_shape_discrete("Model 1") +
scale_colour_discrete("Model 1")
However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
geom_ribbon(alpha=0.2, colour=NA)+
geom_line() +
geom_point() +
facet_wrap(~model)
The other solution are OK, but there is no need to add separator at the very last if using :after or at the very beginning if using :before.
SO:
case :after
.link:after {

padding: 0 1rem;
}
.link:last-child:after {
content: '';
}
case :before
.link:before {
content: '|';
padding: 0 1rem;
}
.link:first-child:before {
content: '';
}
How about just > Format only cells that contain - in the drop down box select Blanks
First Activity
startActivity(Intent(this, SecondActivity::class.java)
.putExtra("key", "value"))
Second Activity
val value = getIntent().getStringExtra("key")
Suggestion
Always put keys in constant file for more managed way.
companion object {
val PUT_EXTRA_USER = "user"
}
startActivity(Intent(this, SecondActivity::class.java)
.putExtra(PUT_EXTRA_USER, "value"))
The other way to set default checked on radio buttons, especially if you're using angularjs is setting the 'ng-checked' flag to "true"
eg: <input id="d_man" value="M" ng-disabled="some Value" type="radio" ng-checked="true">
Man
the checked="checked" did not work for me..
and you can do that by simple code:
filter:alpha(opacity=30);
-moz-opacity:0.3;
-khtml-opacity: 0.3;
opacity: 0.3;
To check if a lateinit var
were initialised or not use a .isInitialized
on the reference to that property:
if (foo::bar.isInitialized) {
println(foo.bar)
}
This checking is only available for the properties that are accessible lexically, i.e. declared in the same type or in one of the outer types, or at top level in the same file.
contentType
option to false
is used for multipart/form-data
forms that pass files.
When one sets the contentType
option to false
, it forces jQuery not to add a Content-Type header, otherwise, the boundary string will be missing from it. Also, when submitting files via multipart/form-data, one must leave the processData
flag set to false, otherwise, jQuery will try to convert your FormData into a string, which will fail.
Use jQuery's .serialize()
method which creates a text string in standard URL-encoded notation.
You need to pass un-encoded data when using contentType: false
.
Try using new FormData
instead of .serialize():
var formData = new FormData($(this)[0]);
See for yourself the difference of how your formData is passed to your php page by using console.log()
.
var formData = new FormData($(this)[0]);
console.log(formData);
var formDataSerialized = $(this).serialize();
console.log(formDataSerialized);
Having /A without additional parameters other than the filename didn't work for me, but the following code worked fine with /n
string sfile = @".\help\delta-pqca-400-100-300-fc4-user-manual.pdf";
Process myProcess = new Process();
myProcess.StartInfo.FileName = "AcroRd32.exe";
myProcess.StartInfo.Arguments = " /n " + "\"" + sfile + "\"";
myProcess.Start();
As someone familiar with Visual Studio, I've looked at several open source IDE's to replace it, and KDevelop comes the closest IMO to being something that a Visual C++ person can just sit down and start using. When you run the project in debugging mode, it uses gdb but kdevelop pretty much handles the whole thing so that you don't have to know it's gdb; you're just single stepping or assigning watches to variables.
It still isn't as good as the Visual Studio Debugger, unfortunately.

I changed windows password today then Tortoise declined to connect me to SVN server. I got around it by opening a Dos box and doing an "svn co ...". It prompted for the new credential then happily did its work. After that, Tortoise works also.
Yet another possible root cause for this error is if the namespace for the area registration class does not match the namespace for the controller.
E.g. correct naming on controller class:
namespace MySystem.Areas.Customers
{
public class CustomersController : Controller
{
...
}
}
With incorrect naming on area registration class:
namespace MySystem.Areas.Shop
{
public class CustomersAreaRegistration : AreaRegistration
{
...
}
}
(Namespace above should be MySystem.Areas.Customers
.)
Will I ever learn to stop copy and pasting code? Probably not.
static final int PROTEINS = 1
...
myArray[PROTEINS]
You'd normally put "constants" in the class itself. And do note that a compiler is allowed to optimize references to it away, so don't change it unless you recompile all the using classes.
class Foo {
public static final int SIZE = 5;
public static int[] arr = new int[SIZE];
}
class Bar {
int last = arr[Foo.SIZE - 1];
}
Edit cycle... SIZE=4
. Also compile Bar
because you compiler may have just written "4" in the last compilation cycle!

From angular's documentation,
ng-init SHOULD NOT be used for any initialization. It should be used only for aliasing. https://docs.angularjs.org/api/ng/directive/ngInit
onload should be used if any expression needs to be evaluated after a partial view is loaded (by ng-include). https://docs.angularjs.org/api/ng/directive/ngInclude
The major difference between them is when used with ng-include.
<div ng-include="partialViewUrl" onload="myFunction()"></div>
In this case, myFunction is called everytime the partial view is loaded.
<div ng-include="partialViewUrl" ng-init="myFunction()"></div>
Whereas, in this case, myFunction is called only once when the parent view is loaded.
As others have said, it is not possible to out of using post/redirect/get. But at the same time it is quite easy to do what you want to do server side.
In your POST page you simply validate the user input but do not act on it, instead you copy it into a SESSION array. You then redirect back to the main submission page again. Your main submission page starts by checking to see if the SESSION array that you are using exists, and if so copy it into a local array and unset it. From there you can act on it.
This way you only do all your main work once, achieving what you want to do.
As to the question "Can the ps3 and xbxo 360 pull off double precision floating point operations or only single precision and in generel use is the double precision capabilities made use of (if they exist?)."
I believe that both platforms are incapable of double floating point. The original Cell processor only had 32 bit floats, same with the ATI hardware which the XBox 360 is based on (R600). The Cell got double floating point support later on, but I'm pretty sure the PS3 doesn't use that chippery.
It looks like your client is trying to connect to a non-existent server. In a shell window, run:
$ nc -l 5000
before running your Python code. It will act as a server listening on port 5000 for you to connect to. Then you can play with typing into your Python window and seeing it appear in the other terminal and vice versa.
I was looking for the same solution and Pawel gave me 99% of the answer. The only thing that was missing that I needed for the Extension to display was adding the following Razor Code into the cshtml(view) page:
@using programname.Models.Extensions
I was looking for the FirstName, to display in the top right of my NavBar after the user logged in.
I thought I would post this incase it helps someone else, So here is my code:
I created a new folder called Extensions(Under my Models Folder) and created the new class as Pawel specified above: IdentityExtensions.cs
using System.Security.Claims;
using System.Security.Principal;
namespace ProgramName.Models.Extensions
{
public static class IdentityExtensions
{
public static string GetUserFirstname(this IIdentity identity)
{
var claim = ((ClaimsIdentity)identity).FindFirst("FirstName");
// Test for null to avoid issues during local testing
return (claim != null) ? claim.Value : string.Empty;
}
}
}
IdentityModels.cs
:
public class ApplicationUser : IdentityUser
{
//Extended Properties
public string FirstName { get; internal set; }
public string Surname { get; internal set; }
public bool isAuthorized { get; set; }
public bool isActive { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
userIdentity.AddClaim(new Claim("FirstName", this.FirstName));
return userIdentity;
}
}
Then in my _LoginPartial.cshtml
(Under Views/Shared
Folders) I added @using.ProgramName.Models.Extensions
I then added the change to the folling line of code that was going to use the Users First name after Logging in :
@Html.ActionLink("Hello " + User.Identity.GetUserFirstname() + "!", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" })
Perhaps this helps someone else down the line.
print
For your own classes, just def a __str__
method
First, open the file and get all your lines from the file. Then reopen the file in write mode and write your lines back, except for the line you want to delete:
with open("yourfile.txt", "r") as f:
lines = f.readlines()
with open("yourfile.txt", "w") as f:
for line in lines:
if line.strip("\n") != "nickname_to_delete":
f.write(line)
You need to strip("\n")
the newline character in the comparison because if your file doesn't end with a newline character the very last line
won't either.
You're confusing the braces. Do it like this:
target.write("%s \n %s \n %s \n" % (line1, line2, line3))
Or even better, use writelines
:
target.writelines([line1, line2, line3])
If you have Iterable convert to stream and find last element
Iterator<String> sourceIterator = Arrays.asList("one", "two", "three").iterator();
Iterable<String> iterable = () -> sourceIterator;
String last = StreamSupport.stream(iterable.spliterator(), false).reduce((first, second) -> second).orElse(null);
EDIT:This approach has serious limitation. It should work if the object is an iterable one. Please check the comments below.
If you are using Python 3.6 or higher like me there is a convenient alternative to check whether an object has a particular attribute:
if 'attr1' in obj1:
print("attr1 = {}".format(obj1["attr1"]))
However, I'm not sure which is the best approach right now. using hasattr()
, using getattr()
or using in
. Comments are welcome.
As mat1t says - you need to add a NotifyIcon to your application and then use something like the following code to set the tooltip and context menu:
this.notifyIcon.Text = "This is the tooltip";
this.notifyIcon.ContextMenu = new ContextMenu();
this.notifyIcon.ContextMenu.MenuItems.Add(new MenuItem("Option 1", new EventHandler(handler_method)));
This code shows the icon in the system tray only:
this.notifyIcon.Visible = true; // Shows the notify icon in the system tray
The following will be needed if you have a form (for whatever reason):
this.ShowInTaskbar = false; // Removes the application from the taskbar
Hide();
The right click to get the context menu is handled automatically, but if you want to do some action on a left click you'll need to add a Click handler:
private void notifyIcon_Click(object sender, EventArgs e)
{
var eventArgs = e as MouseEventArgs;
switch (eventArgs.Button)
{
// Left click to reactivate
case MouseButtons.Left:
// Do your stuff
break;
}
}
str.startswith
allows you to supply a tuple of strings to test for:
if link.lower().startswith(("js", "catalog", "script", "katalog")):
From the docs:
str.startswith(prefix[, start[, end]])
Return
True
if string starts with theprefix
, otherwise returnFalse
.prefix
can also be a tuple of prefixes to look for.
Below is a demonstration:
>>> "abcde".startswith(("xyz", "abc"))
True
>>> prefixes = ["xyz", "abc"]
>>> "abcde".startswith(tuple(prefixes)) # You must use a tuple though
True
>>>
edit the file /etc/eclipse.ini
, so as to contain entry as;
-Duser.name=myname
Restart the "eclipse" and now, on creation of any new file, with wizard (c/c++/java), it will use "myname" in place of ${user}.
A deadlock is a state of a system in which no single process/thread is capable of executing an action. As mentioned by others, a deadlock is typically the result of a situation where each process/thread wishes to acquire a lock to a resource that is already locked by another (or even the same) process/thread.
There are various methods to find them and avoid them. One is thinking very hard and/or trying lots of things. However, dealing with parallelism is notoriously difficult and most (if not all) people will not be able to completely avoid problems.
Some more formal methods can be useful if you are serious about dealing with these kinds of issues. The most practical method that I'm aware of is to use the process theoretic approach. Here you model your system in some process language (e.g. CCS, CSP, ACP, mCRL2, LOTOS) and use the available tools to (model-)check for deadlocks (and perhaps some other properties as well). Examples of toolset to use are FDR, mCRL2, CADP and Uppaal. Some brave souls might even prove their systems deadlock free by using purely symbolic methods (theorem proving; look for Owicki-Gries).
However, these formal methods typically do require some effort (e.g. learning the basics of process theory). But I guess that's simply a consequence of the fact that these problems are hard.

Update for Java 9 and some neat aliases.
In .bash_profile
:
export JAVA_HOME8=`/usr/libexec/java_home --version 1.8`
export JAVA_HOME9=`/usr/libexec/java_home --version 9`
Note, that for the latest version it is 9
and not 1.9
.
Set active Java:
export JAVA_HOME=$JAVA_HOME8
export PATH=$JAVA_HOME/bin:$PATH
Some additional alias to switch between the different versions:
alias j8='export JAVA_HOME=$JAVA_HOME8; export PATH=$JAVA_HOME/bin:$PATH'
alias j9='export JAVA_HOME=$JAVA_HOME9; export PATH=$JAVA_HOME/bin:$PATH'
Test in terminal:
% j8
% java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
% j9
% java -version
java version "9"
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)

When you have replace: true
you get the following piece of DOM:
<div ng-controller="Ctrl" class="ng-scope">
<div class="ng-binding">hello</div>
</div>
whereas, with replace: false
you get this:
<div ng-controller="Ctrl" class="ng-scope">
<my-dir>
<div class="ng-binding">hello</div>
</my-dir>
</div>
So the replace
property in directives refer to whether the element to which the directive is being applied (<my-dir>
in that case) should remain (replace: false
) and the directive's template should be appended as its child,
OR
the element to which the directive is being applied should be replaced (replace: true
) by the directive's template.
In both cases the element's (to which the directive is being applied) children will be lost. If you wanted to perserve the element's original content/children you would have to translude it. The following directive would do it:
.directive('myDir', function() {
return {
restrict: 'E',
replace: false,
transclude: true,
template: '<div>{{title}}<div ng-transclude></div></div>'
};
});
In that case if in the directive's template you have an element (or elements) with attribute ng-transclude
, its content will be replaced by the element's (to which the directive is being applied) original content.
See example of translusion http://plnkr.co/edit/2DJQydBjgwj9vExLn3Ik?p=preview
See this to read more about translusion.
envsubst
seems exactly like something I wanted to use, but -v
option surprised me a bit.
While envsubst < template.txt
was working fine, the same with option -v
was not working:

As I wrote, this was not working:
$ envsubst -v < template.txt
envsubst: missing arguments
$ cat template.txt | envsubst -v
envsubst: missing arguments
I had to do this to make it work:
TEXT=`cat template.txt`; envsubst -v "$TEXT"
Maybe it helps someone.
You need to have at least the same number of columns and each column has to be defined in exactly the same way, i.e. a varchar column can't be inserted into an int column.
For bulk transfer, check the documentation for the SQL implementation you're using. There are often tools available to bulk transfer data from one table to another. For SqlServer 2005, for example, you could use the SQL Server Import and Export Wizard. Right-click on the database you're trying to move data around in and click Export to access it.
UITableView
has a tableHeaderView
property. Set that to whatever view you want up there.
Use a new UIView
as a container, add a text label and an image view to that new UIView
, then set tableHeaderView
to the new view.
For example, in a UITableViewController
:
-(void)viewDidLoad
{
// ...
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
[headerView addSubview:imageView];
UILabel *labelView = [[UILabel alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
[headerView addSubview:labelView];
self.tableView.tableHeaderView = headerView;
[imageView release];
[labelView release];
[headerView release];
// ...

In Linux Kernel, present pages are physical pages of RAM which kernel can see. Literally, present pages is total size of RAM in 4KB unit.
grep present /proc/zoneinfo | awk '{sum+=$2}END{print sum*4,"KB"}'
The 'MemTotal' form /proc/meminfo is the total size of memory managed by buddy system.And we can also compute it like this:
grep managed /proc/zoneinfo | awk '{sum+=$2}END{print sum*4,"KB"}'
The bitmap constructor has resizing built in.
Bitmap original = (Bitmap)Image.FromFile("DSC_0002.jpg");
Bitmap resized = new Bitmap(original,new Size(original.Width/4,original.Height/4));
resized.Save("DSC_0002_thumb.jpg");

To execute your command directly from within C#, you would use the SqlCommand class.
Quick sample code using paramaterized SQL (to avoid injection attacks) might look like this:
string queryString = "SELECT tPatCulIntPatIDPk, tPatSFirstname, tPatSName, tPatDBirthday FROM [dbo].[TPatientRaw] WHERE tPatSName = @tPatSName";
string connectionString = "Server=.\PDATA_SQLEXPRESS;Database=;User Id=sa;Password=2BeChanged!;";
using (SqlConnection connection = new SqlConnection(connectionString))
{
SqlCommand command = new SqlCommand(queryString, connection);
command.Parameters.AddWithValue("@tPatSName", "Your-Parm-Value");
connection.Open();
SqlDataReader reader = command.ExecuteReader();
try
{
while (reader.Read())
{
Console.WriteLine(String.Format("{0}, {1}",
reader["tPatCulIntPatIDPk"], reader["tPatSFirstname"]));// etc
}
}
finally
{
// Always call Close when done reading.
reader.Close();
}
}

Express version:
"dependencies": {
"body-parser": "^1.19.0",
"express": "^4.17.1"
}
Optional parameter are very much handy, you can declare and use them easily using express:
app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
console.log("category Id: "+req.params.cId);
console.log("product ID: "+req.params.pId);
if (req.params.batchNo){
console.log("Batch No: "+req.params.batchNo);
}
});
In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'
Now I can call with only categoryId and productId or with all three-parameter.

i was facing this problem and i checked all the answers and nothing worked for me, but then i reset mail.php and didn't touch it and set the mail server from .env file and it worked perfectly, hope this will save the time for someone :).
By using the page source you will get the whole HTML code.
So first decide the block of code or tag in which you require to retrieve the data or to click the element..
options = driver.find_elements_by_name_("XXX")
for option in options:
if option.text == "XXXXXX":
print(option.text)
option.click()
You can find the elements by name, XPath, id, link and CSS path.
React.MouseEvent works for me:
private onClick = (e: React.MouseEvent<HTMLInputElement>) => {
let button = e.target as HTMLInputElement;
}
Assuming you only want to disallow strings that match the regex completely (i.e., mmbla
is okay, but mm
isn't), this is what you want:
^(?!(?:m{2}|t)$).*$
(?!(?:m{2}|t)$)
is a negative lookahead; it says "starting from the current position, the next few characters are not mm
or t
, followed by the end of the string." The start anchor (^
) at the beginning ensures that the lookahead is applied at the beginning of the string. If that succeeds, the .*
goes ahead and consumes the string.
FYI, if you're using Java's matches()
method, you don't really need the the ^
and the final $
, but they don't do any harm. The $
inside the lookahead is required, though.
import java.util.*;
public class MatchBrackets {
public static void main(String[] argh) {
String input = "[]{[]()}";
System.out.println (input);
char [] openChars = {'[','{','('};
char [] closeChars = {']','}',')'};
Stack<Character> stack = new Stack<Character>();
for (int i = 0; i < input.length(); i++) {
String x = "" +input.charAt(i);
if (String.valueOf(openChars).indexOf(x) != -1)
{
stack.push(input.charAt(i));
}
else
{
Character lastOpener = stack.peek();
int idx1 = String.valueOf(openChars).indexOf(lastOpener.toString());
int idx2 = String.valueOf(closeChars).indexOf(x);
if (idx1 != idx2)
{
System.out.println("false");
return;
}
else
{
stack.pop();
}
}
}
if (stack.size() == 0)
System.out.println("true");
else
System.out.println("false");
}
}
Actually, it is
private const int TheAnswer = 42;
At least if you look at the .NET library, which IMO is the best way to decide naming conventions - so your code doesn't look out of place.
After rigorous testing, I found out that the source of my problem is Hash::make('password'). Apparently this kept generating a different hash each time. SO I replaced this with my own hashing function (wrote previously in codeigniter) and viola! things worked well.
Thanks again for helping out :) Really appreciate it!
When working with 4 large Db2 tables I have not only found the limit but it caused me to look really bad to a boss who thought that I could append all four tables (each with over 900,000 rows) to one large table. the real life result was that regardless of how many times I tried the Table (which had exactly 34 columns - 30 text and 3 integer) would spit out some cryptic message "Cannot open database unrecognized format or the file may be corrupted". Bottom Line is Less than 1,500,000 records and just a bit more than 1,252,000 with 34 rows.
Assuming join
wasn't designed that way (which it is, as ATOzTOA pointed out), and it only took two parameters, you could still use the built-in reduce
:
>>> reduce(os.path.join,["c:/","home","foo","bar","some.txt"])
'c:/home\\foo\\bar\\some.txt'
Same output like:
>>> os.path.join(*["c:/","home","foo","bar","some.txt"])
'c:/home\\foo\\bar\\some.txt'
Just for completeness and educational reasons (and for other situations where *
doesn't work).
Hint for Python 3
reduce
was moved to the functools
module.
If you always want it to go to /C, use an absolute path when you write the file.

This can work in Objective C ARC.Use CFBridgingRelease to cast a Core Foundation-style object as an Objective-C object and transfer ownership of the object to ARC .See Function CFBridgingRelease here.

return CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes

You could do:
radio1.SelectedIndex = 1;
But this is the most simple form and would most likely become problematic as your UI grows. Say, for instance, if a team member inserts an item in the RadioButtonList
above option2
but doesn't know we use magic numbers in code-behind to select - now the app selects the wrong index!
Maybe you want to look into using FindControl in order to determine the ListItem
actually required, by name, and selecting appropriately. For instance:
//omitting possible null reference checks...
var wantedOption = radio1.FindControl("option2").Selected = true;
The following works for me:
Map<String, String> propertyMap = getJsonAsMap(json);
where getJsonAsMap
is defined like so:
public HashMap<String, String> getJsonAsMap(String json)
{
try
{
ObjectMapper mapper = new ObjectMapper();
TypeReference<Map<String,String>> typeRef = new TypeReference<Map<String,String>>() {};
HashMap<String, String> result = mapper.readValue(json, typeRef);
return result;
}
catch (Exception e)
{
throw new RuntimeException("Couldnt parse json:" + json, e);
}
}
Note that this will fail if you have child objects in your json (because they're not a String
, they're another HashMap
), but will work if your json is a key value list of properties like so:
{
"client_id": "my super id",
"exp": 1481918304,
"iat": "1450382274",
"url": "http://www.example.com"
}
One-liner to list directories only from "here".
With file count.
for i in `ls -d */`; do g=`find ./$i -type f -print| wc -l`; echo "Directory $i contains $g files."; done
This should do the trick:
mapper.readValue(fileReader, MyClass.class);
I say should because I'm using that with a String
, not a BufferedReader
but it should still work.
Here's my code:
String inputString = // I grab my string here
MySessionClass sessionObject;
try {
ObjectMapper objectMapper = new ObjectMapper();
sessionObject = objectMapper.readValue(inputString, MySessionClass.class);
Here's the official documentation for that call: http://jackson.codehaus.org/1.7.9/javadoc/org/codehaus/jackson/map/ObjectMapper.html#readValue(java.lang.String, java.lang.Class)
You can also define a custom deserializer when you instantiate the ObjectMapper
:
http://wiki.fasterxml.com/JacksonHowToCustomDeserializers
Edit:
I just remembered something else. If your object coming in has more properties than the POJO
has and you just want to ignore the extras you'll want to set this:
objectMapper.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);
Or you'll get an error that it can't find the property to set into.
Create with Resource Method
php artisan make:controller --resource ControllerName --model=ModelName

php artisan make:controller --resource path/ControllerName --model=ModelName
To get the type, use the builtin type
function. With the in
operator, you can test if the type is a numpy type by checking if it contains the string numpy
;
In [1]: import numpy as np
In [2]: a = np.array([1, 2, 3])
In [3]: type(a)
Out[3]: <type 'numpy.ndarray'>
In [4]: 'numpy' in str(type(a))
Out[4]: True
(This example was run in IPython, by the way. Very handy for interactive use and quick tests.)
The File
class represents the "idea" of a file, not an actual handle to use for I/O. This is why the File
class has a .exists()
method, to tell you if the file exists or not. (How can you have a File
object that doesn't exist?)
By contrast, constructing a new FileInputStream(new File("/my/file"))
gives you an actual stream to read bytes from.
On my system, I was just missing the Linux package.
sudo apt install libopenmpi-dev

You can use [weak self] or [unowned self] in the capture list prior to your parameters of the block. The capture list is optional syntax.
[unowned self]
works good here because the cell will never be nil. Otherwise you can use [weak self]
You can get entire post body into a POJO. Following is something similar
@RequestMapping(

produces = "application/json",
consumes = ["application/json"])

public Boolean editWinner( @RequestBody Pojo pojo) {
Where each field in Pojo (Including getter/setters) should match the Json request object that the controller receives..

Make sure you have SQLCMD enabled by clicking on the Query > SQLCMD mode option in the management studio.
Suppose you have four .sql files (script1.sql,script2.sql,script3.sql,script4.sql
) in a folder c:\scripts
.
Create a main script file (Main.sql) with the following:
:r c:\Scripts\script1.sql
:r c:\Scripts\script2.sql
:r c:\Scripts\script3.sql
:r c:\Scripts\script4.sql
Save the Main.sql in c:\scripts itself.
Create a batch file named ExecuteScripts.bat
with the following:
SQLCMD -E -d<YourDatabaseName> -ic:\Scripts\Main.sql
PAUSE
Remember to replace <YourDatabaseName>
with the database you want to execute your scripts. For example, if the database is "Employee", the command would be the following:
SQLCMD -E -dEmployee -ic:\Scripts\Main.sql
PAUSE
Execute the batch file by double clicking the same.

def __init__(self, data):
self.data = data
self.rChild = None

def insert(self, btreeNode):
if self.data > btreeNode.data: #insert left
if self.lChild == None:
self.lChild = btreeNode
else:
self.lChild.insert(btreeNode)

def main():
btreeRoot = BTreeNode(5)

980 is not the "defacto standard", you'll generally see most people targeting a size a little bit less than 1024px wide to account for browser chrome such as scrollbars, etc.
Usually people target between 960 and 990px wide. Often people use a grid system (like 960.gs) which is opinionated about what the default width should be.
Also note, just recently the most common screen size now averages quite a bit bigger than 1024px wide, ranking in at 1366px wide. See http://techcrunch.com/2012/04/11/move-over-1024x768-the-most-popular-screen-resolution-on-the-web-is-now-1366x768/
For me this issue was caused by the file encoding format being wrong.
I used another editor and it was saved as UTF-8-BOM
so the very first line I had was @echo off
but there was a hidden character in the front of it.
So I changed the encoding to plain old ANSI
text, and then the issue went away.
^(?!my)\w+$
should work.
It first ensures that it's not possible to match my
at the start of the string, and then matches alphanumeric characters until the end of the string. Whitespace anywhere in the string will cause the regex to fail. Depending on your input you might want to either strip whitespace in the front and back of the string before passing it to the regex, or use add optional whitespace matchers to the regex like ^\s*(?!my)(\w+)\s*$
. In this case, backreference 1 will contain the name of the variable.
And if you need to ensure that your variable name starts with a certain group of characters, say [A-Za-z_]
, use
^(?!my)[A-Za-z_]\w*$
Note the change from +
to *
.

Run dos2unix or similar utility on it to remove the carriage returns (^M).
This message indicates that your file has dos-style lineendings:

Utilities like dos2unix
will fix it:
dos2unix <backup.bash >improved-backup.sh
Or, if no such utility is installed, you can accomplish the same thing with translate:
tr -d "\015\032" <backup.bash >improved-backup.sh
As for how those characters got there in the first place, @MadPhysicist had some good comments.

RemoteIPInternalProxy 172.16.0.0/12
LogFormat "%a %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
The one-to-many table relationship looks as follows:
In a relational database system, a one-to-many table relationship links two tables based on a Foreign Key
column in the child which references the Primary Key
of the parent table row.
In the table diagram above, the post_id
column in the post_comment
table has a Foreign Key
relationship with the post
table id Primary Key
column:
ALTER TABLE
post_comment
ADD CONSTRAINT
fk_post_comment_post_id
FOREIGN KEY (post_id) REFERENCES post
The one-to-one table relationship looks as follows:
In a relational database system, a one-to-one table relationship links two tables based on a Primary Key
column in the child which is also a Foreign Key
referencing the Primary Key
of the parent table row.
Therefore, we can say that the child table shares the Primary Key
with the parent table.
In the table diagram above, the id
column in the post_details
table has also a Foreign Key
relationship with the post
table id
Primary Key
column:
ALTER TABLE
post_details
ADD CONSTRAINT
fk_post_details_id
FOREIGN KEY (id) REFERENCES post
The many-to-many table relationship looks as follows:
In a relational database system, a many-to-many table relationship links two parent tables via a child table which contains two Foreign Key
columns referencing the Primary Key
columns of the two parent tables.
In the table diagram above, the post_id
column in the post_tag
table has also a Foreign Key
relationship with the post
table id Primary Key
column:
ALTER TABLE
post_tag
ADD CONSTRAINT
fk_post_tag_post_id
FOREIGN KEY (post_id) REFERENCES post
And, the tag_id
column in the post_tag
table has a Foreign Key
relationship with the tag
table id Primary Key
column:
ALTER TABLE
post_tag
ADD CONSTRAINT
fk_post_tag_tag_id
FOREIGN KEY (tag_id) REFERENCES tag

The value must not contain any space characters.
id="a b"
<-- find the space character in that VaLuE.
That said, you can style multiple IDs. But if you're following spec, the answer is no.
If you want to use the toDF
method, you have to convert your RDD
of Array[String]
into a RDD
of a case class. For example, you have to do:
case class Test(id:String,filed2:String)
val myFile = sc.textFile("file.txt")
val df= myFile.map( x => x.split(";") ).map( x=> Test(x(0),x(1)) ).toDF()
It will only push the new commits. It won't push the whole "master" branch. That is part of the benefit of working with a Distributed Version Control System. Git figures out what is actually needed and only pushes those pieces. If the branch you are on has been changed and pushed by someone else you'll need to pull first. Then push your commits.
Downloading Wget is not necessary; the .NET Framework has web client classes built in.

Since YouTube has deprecated the showinfo parameter you can trick the player. Youtube will always try to center its video but logo, title, watch later button etc.. will always stay at the left and right side respectively.
So what you can do is put your Youtube iframe inside some div:
<div class="frame-container">
<iframe></iframe>
</div>
Then you can increase the size of frame-container to be out of browser window, while aligning it so that the iframe video comes to the center. Example:
.frame-container {
position: relative;
padding-bottom: 56.25%; /* 16:9 */
padding-top: 25px;
width: 300%; /* enlarge beyond browser width */
left: -100%; /* center */
}
.frame-container iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
Finnaly put everything inside a wrapper div to prevent page stretching due to 300% width:
<div class="wrapper">
<div class="frame-container">
<iframe></iframe>
</div>
</div>
.wrapper {
overflow: hidden;
max-width: 100%;
}
For your current structure, you could also try the following:
select cash.Country, cash.Value, cheque.Value, cash.Value + cheque.Value as [Total]
from Cash
join Cheque
on cash.Country = cheque.Country
I think I prefer a union between the two tables, and a group by on the country name as mentioned above.
But I would also recommend normalising your tables. Ideally you'd have a country table, with Id and Name, and a payments table with: CountryId (FK to countries), Total, Type (cash/cheque)
I struggled with the same issue when trying to feed floats to the classifiers. I wanted to keep floats and not integers for accuracy. Try using regressor algorithms. For example:
import numpy as np
from sklearn import linear_model
from sklearn import svm
classifiers = [
svm.SVR(),
linear_model.SGDRegressor(),
linear_model.BayesianRidge(),
linear_model.LassoLars(),
linear_model.ARDRegression(),
linear_model.PassiveAggressiveRegressor(),
linear_model.TheilSenRegressor(),
linear_model.LinearRegression()]
trainingData = np.array([ [2.3, 4.3, 2.5], [1.3, 5.2, 5.2], [3.3, 2.9, 0.8], [3.1, 4.3, 4.0] ])
trainingScores = np.array( [3.4, 7.5, 4.5, 1.6] )
predictionData = np.array([ [2.5, 2.4, 2.7], [2.7, 3.2, 1.2] ])
for item in classifiers:
print(item)
clf = item
clf.fit(trainingData, trainingScores)
print(clf.predict(predictionData),'\n')
From Microsoft.PowerShell.Archive
you can use:
E.g.:
Create result.zip
from the entire Test
folder:
Compress-Archive -Path C:\Test -DestinationPath C:\result
Extract the content of result.zip
in the specified Test
folder:
Expand-Archive -Path result.zip -DestinationPath C:\Test

Here is SQLFiddle demo
I use volatile fields when said field is ONLY UPDATED by its owner thread and the value is only read by other threads, you can think of it as a publish/subscribe scenario where there are many observers but only one publisher. However if those observers must perform some logic based on the value of the field and then push back a new value then I go with Atomic* vars or locks or synchronized blocks, whatever suits me best. In many concurrent scenarios it boils down to get the value, compare it with another one and update if necessary, hence the compareAndSet and getAndSet methods present in the Atomic* classes.
Check the JavaDocs of the java.util.concurrent.atomic package for a list of Atomic classes and an excellent explanation of how they work (just learned that they are lock-free, so they have an advantage over locks or synchronized blocks)
In this instance, your div
elements have been changed from block
level elements to inline
elements. A typical characteristic of inline
elements is that they respect the whitespace in the markup. This explains why a gap of space is generated between the elements. (example)
There are a few solutions that can be used to solve this.
Example 1 - Comment the whitespace out: (example)
<div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div>
Example 2 - Remove the line breaks: (example)
<div>text</div><div>text</div><div>text</div><div>text</div><div>text</div>
Example 3 - Close part of the tag on the next line (example)
<div>text</div
><div>text</div
><div>text</div
><div>text</div
><div>text</div>
Example 4 - Close the entire tag on the next line: (example)
<div>text
</div><div>text
</div><div>text
</div><div>text
</div><div>text
</div>
font-size
Since the whitespace between the inline
elements is determined by the font-size
, you could simply reset the font-size
to 0
, and thus remove the space between the elements.
Just set font-size: 0
on the parent elements, and then declare a new font-size
for the children elements. This works, as demonstrated here (example)
#parent {
font-size: 0;
}
#child {
font-size: 16px;
}
This method works pretty well, as it doesn't require a change in the markup; however, it doesn't work if the child element's font-size
is declared using em
units. I would therefore recommend removing the whitespace from the markup, or alternatively floating the elements and thus avoiding the space generated by inline
elements.
display: flex
In some cases, you can also set the display
of the parent element to flex
. (example)
This effectively removes the spaces between the elements in supported browsers. Don't forget to add appropriate vendor prefixes for additional support.
.parent {
display: flex;
}
.parent > div {
display: inline-block;
padding: 1em;
border: 2px solid #f00;
}
.parent {_x000D_
display: flex;_x000D_
}_x000D_
.parent > div {_x000D_
display: inline-block;_x000D_
padding: 1em;_x000D_
border: 2px solid #f00;_x000D_
}
_x000D_
<div class="parent">_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
</div>
_x000D_
It is incredibly unreliable to use negative margins to remove the space between inline
elements. Please don't use negative margins if there are other, more optimal, solutions.
As Nayan said the Path has to updated properly in my case the apache-maven was installed in C:\apache-maven and settings.xml was found inside C:\apache-maven\conf\settings.xml
if this doesn't work go to your local repos
in my case C:\Users\<<"name">>.m2\
and search for .lastUpdated and delete them
then build the maven
Here is a bit more advanced/production-ready version:
public static class CollectionExtensions

public static TCol AddRange<TCol, TItem>(this TCol destination, IEnumerable<TItem> source)
where TCol : ICollection<TItem>
{
if(destination == null) throw new ArgumentNullException(nameof(destination));
if(source == null) throw new ArgumentNullException(nameof(source));
// don't cast to IList to prevent recursion
if (destination is List<TItem> list)
{
list.AddRange(source);
return destination;
}
foreach (var item in source)
{
destination.Add(item);
}
return destination;
}
}
After misunderstanding, I finally got what you are trying to do. You should check your server configuration files; are you using apache2 or some other server software?
Look for lines that start with LoadModule php
...
There probably are configuration files/directories named mods
or something like that, start from there.
You could also check output from php -r 'phpinfo();' | grep php
and compare lines to phpinfo();
from web server.
php
interactively:(so you can paste/write code in the console)
php -a
php -f file.php
php -f file.php > results.html
To run only small part, one line or like, you can use:
php -r '$x = "Hello World"; echo "$x\n";'
If you are running linux then do man php
at console.
if you need/want to run php through fpm, use cli fcgi
SCRIPT_NAME="file.php" SCRIP_FILENAME="file.php" REQUEST_METHOD="GET" cgi-fcgi -bind -connect "/var/run/php-fpm/php-fpm.sock"
where /var/run/php-fpm/php-fpm.sock is your php-fpm socket file.
It is 20 Minutes according to MSDN
From MSDN:
Optional TimeSpan attribute.
Specifies the number of minutes a session can be idle before it is abandoned. The timeout attribute cannot be set to a value that is greater than 525,601 minutes (1 year) for the in-process and state-server modes. The session timeout configuration setting applies only to ASP.NET pages. Changing the session timeout value does not affect the session time-out for ASP pages. Similarly, changing the session time-out for ASP pages does not affect the session time-out for ASP.NET pages. The default is 20 minutes.
If you need more flexibility in selecting the processes use
for KILLPID in `ps ax | grep 'my_pattern' | awk ' { print $1;}'`; do
kill -9 $KILLPID;
done
You can use grep -e etc.
For those using RestSharp, it might fail when using SimpleAuthenticator (possibly due to not using ISO-8859-1 behind the scene). I managed to get it done by explicitly sending Basic Authentication headers:
string username = "...";
string password = "...";
public IRestResponse GetResponse(string url, Method method = Method.GET)
{
string encoded = Convert.ToBase64String(Encoding.GetEncoding("ISO-8859-1").GetBytes($"{username}:{password}"));
var client = new RestClient(url);
var request = new RestRequest(method );
request.AddHeader("Authorization", $"Basic {encoded}");
IRestResponse response = client.Execute(request);
return response;
}
var response = GetResponse(url);
txtResult.Text = response.Content;
iframe now supports srcdoc which can be used to specify the HTML content of the page to show in the inline frame.
Java 8 way of doing,
String firstKey = map.keySet().stream().findFirst().get();
If all elements of the list may be used as dictionary keys (i.e. they are all hashable) this is often faster. Python Programming FAQ

d[x] = 1
mylist = list(d.keys())
I had the same problem. But I also had to perform additional steps. Here is what I did.
Perform the following steps (Only 64bit version of SQL Server 2005 Developer Edition tested on Windows 8 Pro 64bit)
For STEP 5 above: Although I didn't try looking into SP4 / SP3 setup for SQLSERVR.EXE and SQLOS.DLL but if you don't have an existing installation of SQL Server 2005 SP3/SP4 then maybe try looking into the SP3/SP4 EXE (Compressed file). I am not sure if this may help. In any case you can create a VM and install SQL Server 2005 with SP3/Sp4 to copy the files for Windows 8
A clean and easy solution (C#):
static class Utilities {
public static List<T> GetAllControls<T>(this Control container) where T : Control {
List<T> controls = new List<T>();
if (container.Controls.Count > 0) {
controls.AddRange(container.Controls.OfType<T>());
foreach (Control c in container.Controls) {
controls.AddRange(c.GetAllControls<T>());
}
}
return controls;
}
}
Get all textboxes:
List<TextBox> textboxes = myControl.GetAllControls<TextBox>();
The tool you want is ps. To get information about what java programs are doing:
ps -F -C java
To get information about http:
ps -F -C httpd
If your program is ending before you get a chance to run these, open another terminal and run:
while true; do ps -F -C myCoolCode ; sleep 0.5s ; done
As of VisualStudio 2015, if you keep all your code in one solution, you can share code by adding a shared project. Then add a reference to this shared project for each project you want to use the code in, as well as the proper using directives.
It worked for me after adding the following dependency in pom,
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.3.0.Final</version>

you can use backslash '\' if you want to display a single quote in your text.

Talking about JAXB limitation, a solution when having the same name for different attributes is adding inline jaxb customizations to the xsd:

or external customizations...
You can see further informations on : http://jaxb.java.net/tutorial/section_5_3-Overriding-Names.html
I think you need to specify a different resolution when saving the figure to a file:
fig = matplotlib.pyplot.figure()
# generate your plot
fig.savefig("myfig.png",dpi=600)
Specifying a large dpi value should have a similar effect as maximizing the GUI window.
I took Nico Burns's answer and made it using jQuery:
div contentEditable="true"
You'll need jQuery 1.6 or higher:
savedRanges = new Object();
$('div[contenteditable="true"]').focus(function(){
var s = window.getSelection();
var t = $('div[contenteditable="true"]').index(this);
if (typeof(savedRanges[t]) === "undefined"){
savedRanges[t]= new Range();
} else if(s.rangeCount > 0) {
s.removeAllRanges();
s.addRange(savedRanges[t]);
}
}).bind("mouseup keyup",function(){
var t = $('div[contenteditable="true"]').index(this);
savedRanges[t] = window.getSelection().getRangeAt(0);
}).on("mousedown click",function(e){
if(!$(this).is(":focus")){
e.stopPropagation();
e.preventDefault();
$(this).focus();
}
});

The WebClient class should be more than capable of handling the functionality you describe, for example:
System.Net.WebClient wc = new System.Net.WebClient();
byte[] raw = wc.DownloadData("http://www.yoursite.com/resource/file.htm");
string webData = System.Text.Encoding.UTF8.GetString(raw);
or (further to suggestion from Fredrick in comments)
System.Net.WebClient wc = new System.Net.WebClient();
string webData = wc.DownloadString("http://www.yoursite.com/resource/file.htm");
When you say it took 30 seconds, can you expand on that a little more? There are many reasons as to why that could have happened. Slow servers, internet connections, dodgy implementation etc etc.
You could go a level lower and implement something like this:
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://www.yoursite.com/resource/file.htm");
using (StreamWriter streamWriter = new StreamWriter(webRequest.GetRequestStream(), Encoding.UTF8))
{
streamWriter.Write(requestData);
}
string responseData = string.Empty;
HttpWebResponse httpResponse = (HttpWebResponse)webRequest.GetResponse();
using (StreamReader responseReader = new StreamReader(httpResponse.GetResponseStream()))
{
responseData = responseReader.ReadToEnd();
}
However, at the end of the day the WebClient class wraps up this functionality for you. So I would suggest that you use WebClient and investigate the causes of the 30 second delay.
Your selector is wrong, you were probably looking for

For Oracle DBs, see this question: How can multiple rows be concatenated into one in Oracle without creating a stored procedure?
The best answer appears to be by @Emmanuel, using the built-in LISTAGG() function, available in Oracle 11g Release 2 and later.
SELECT question_id,
LISTAGG(element_id, ',') WITHIN GROUP (ORDER BY element_id)
FROM YOUR_TABLE;
GROUP BY question_id
as @user762952 pointed out, and according to Oracle's documentation http://www.oracle-base.com/articles/misc/string-aggregation-techniques.php, the WM_CONCAT() function is also an option. It seems stable, but Oracle explicitly recommends against using it for any application SQL, so use at your own risk.
Other than that, you will have to write your own function; the Oracle document above has a guide on how to do that.
easy way is:
a = [1,2]
d = {}
for i in a:
d[i]=[i, ]
print(d)
{'1': [1, ], '2':[2, ]}
Powder's comment may go undetected like I missed it so many times,. So with the hope of making it more visible, I will re-iterate his point.
Sometimes using image = array(img).reshape(a,b,c,d)
will reshape alright but from experience, my kernel crashes every time I try to use the new dimension in an operation. The safest to use is
np.expand_dims(img, axis=0)
It works perfect every time. I just can't explain why. This link has a great explanation and examples regarding its usage.
Cannot update first answer.
Anyway, after Go1 release, there are some breaking changes, so I updated as shown below:
package main
import (
"os"
"bufio"
"bytes"
"io"
"fmt"
"strings"
)
// Read a whole file into the memory and store it as array of lines
func readLines(path string) (lines []string, err error) {
var (
file *os.File
part []byte
prefix bool
)
if file, err = os.Open(path); err != nil {
return
}
defer file.Close()
reader := bufio.NewReader(file)
buffer := bytes.NewBuffer(make([]byte, 0))
for {
if part, prefix, err = reader.ReadLine(); err != nil {
break
}
buffer.Write(part)
if !prefix {
lines = append(lines, buffer.String())
buffer.Reset()
}
}
if err == io.EOF {
err = nil
}
return
}
func writeLines(lines []string, path string) (err error) {
var (
file *os.File
)
if file, err = os.Create(path); err != nil {
return
}
defer file.Close()
//writer := bufio.NewWriter(file)
for _,item := range lines {
//fmt.Println(item)
_, err := file.WriteString(strings.TrimSpace(item) + "\n");
//file.Write([]byte(item));
if err != nil {
//fmt.Println("debug")
fmt.Println(err)
break
}
}
/*content := strings.Join(lines, "\n")
_, err = writer.WriteString(content)*/
return
}
func main() {
lines, err := readLines("foo.txt")
if err != nil {
fmt.Println("Error: %s\n", err)
return
}
for _, line := range lines {
fmt.Println(line)
}
//array := []string{"7.0", "8.5", "9.1"}
err = writeLines(lines, "foo2.txt")
fmt.Println(err)
}
http://example.com/ may resolve to a different VirtualHost than https://example.com/ (which, as the Host header is not sent, responds to the default for that IP), so the two are treated as separate domains and thus subject to crossdomain JS restrictions.
JSON callbacks may let you avoid this.
As others have pointed out, output can be buffered within your program before a console or shell has a chance to see it.
On unix-like systems, including macs, stdout
has line-based buffering by default. This means that your program empties its stdout
buffer as soon as it sees a newline.
However, on windows, newlines are no longer special, and full buffering is used. Windows doesn't support line buffering at all; see the msdn page on setvbuf.
So on windows, a good approach is to completely shut off stdout
buffering like so:
setvbuf (stdout, NULL, _IONBF, 0);
I am not able to add a comment to M. Kiewisch since I do not have enough reputation points (only have 41 but need more than 50 to comment).
Anyway, just want to point out that M. Kiewisch solution does not work as is and may need more tweaking. Consider for example
>>> df = pd.DataFrame({'a': [1, 2, 3, 5], 'b': [4, np.NaN, 6, 4]})
>>> df
a b
0 1 4.0
1 2 NaN
2 3 6.0
3 5 4.0
>>> df.groupby(['b']).sum()
a
b
4.0 6
6.0 3
>>> df.astype(str).groupby(['b']).sum()
a
b
4.0 15
6.0 3
nan 2
which shows that for group b=4.0, the corresponding value is 15 instead of 6. Here it is just concatenating 1 and 5 as strings instead of adding it as numbers.
We used this code to mitigate potential variability in stack trace index - now just call methodName util:
public class MethodNameTest {
private static final int CLIENT_CODE_STACK_INDEX;
static {
// Finds out the index of "this code" in the returned stack trace - funny but it differs in JDK 1.5 and 1.6
int i = 0;
for (StackTraceElement ste : Thread.currentThread().getStackTrace()) {
i++;
if (ste.getClassName().equals(MethodNameTest.class.getName())) {
break;
}
}
CLIENT_CODE_STACK_INDEX = i;
}
public static void main(String[] args) {
System.out.println("methodName() = " + methodName());
System.out.println("CLIENT_CODE_STACK_INDEX = " + CLIENT_CODE_STACK_INDEX);
}
public static String methodName() {
return Thread.currentThread().getStackTrace()[CLIENT_CODE_STACK_INDEX].getMethodName();
}
}
Seems overengineered, but we had some fixed number for JDK 1.5 and were a bit surprised it changed when we moved to JDK 1.6. Now it's the same in Java 6/7, but you just never know. It is not proof to changes in that index during runtime - but hopefully HotSpot doesn't do that bad. :-)
Note that java11 now offers a new HTTP api HttpClient, which supports fully asynchronous operation, using java's CompletableFuture.
It also supports a synchronous version, with calls like send, which is synchronous, and sendAsync, which is asynchronous.
Example of an async request (taken from the apidoc):
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("https://example.com/"))
.timeout(Duration.ofMinutes(2))
.header("Content-Type", "application/json")

According to the latest documentation about PyMongo titled Insert a Document (insert is deprecated) and following defensive approach, you should insert and update as follows:
result = mycollection.insert_one(post)
post = mycollection.find_one({'_id': result.inserted_id})
if post is not None:
post['newfield'] = "abc"
mycollection.save(post)
use this code for set value in input tag by another id.
$(".formdata").val(document.getElementById("fsd").innerHTML);
or use this code for set value in input tag using classname="formdata"
$(".formdata").val("hello");
Use a div #overlay
with your loading info / .gif that will cover all your page:
<div id="overlay">
<img src="loading.gif" alt="Loading" />
Loading...
</div>
jQuery:
$(window).load(function(){
// PAGE IS FULLY LOADED
// FADE OUT YOUR OVERLAYING DIV
$('#overlay').fadeOut();
});
Here's an example with a Loading bar:
<div id="overlay">
<div id="progstat"></div>
<div id="progress"></div>
</div>
<div id="container">
<img src="http://placehold.it/3000x3000/cf5">
</div>
CSS:
*{margin:0;}
body{ font: 200 16px/1 sans-serif; }
img{ width:32.2%; }
#overlay{
position:fixed;
z-index:99999;
top:0;
left:0;
bottom:0;
right:0;
background:rgba(0,0,0,0.9);
transition: 1s 0.4s;
}
#progress{
height:1px;
background:#fff;
position:absolute;
width:0; /* will be increased by JS */
top:50%;
}
#progstat{
font-size:0.7em;
letter-spacing: 3px;
position:absolute;
top:50%;
margin-top:-40px;
width:100%;
text-align:center;
color:#fff;
}
JavaScript:
;(function(){
function id(v){ return document.getElementById(v); }
function loadbar() {
var ovrl = id("overlay"),
prog = id("progress"),
stat = id("progstat"),
img = document.images,
c = 0,
tot = img.length;
if(tot == 0) return doneLoading();
function imgLoaded(){
c += 1;
var perc = ((100/tot*c) << 0) +"%";
prog.style.width = perc;
stat.innerHTML = "Loading "+ perc;
if(c===tot) return doneLoading();
}
function doneLoading(){
ovrl.style.opacity = 0;
setTimeout(function(){
ovrl.style.display = "none";
}, 1200);
}
for(var i=0; i<tot; i++) {
var tImg = new Image();
tImg.onload = imgLoaded;
tImg.onerror = imgLoaded;
tImg.src = img[i].src;
}
}
document.addEventListener('DOMContentLoaded', loadbar, false);
}());
Yep! Use the link:
https://m.google.com/app/plus/x/?v=compose&content=YOUR_TEXT
It's SHARE url (not used for plus one) button.
If this will not work (not for me) try this url:
https://plusone.google.com/_/+1/confirm?hl=ru&url=_URL_&title=_TITLE_
Or see this solution:
Adding a Google Plus (one or share) link to an email newsletter
Although Time Complexity of selection sort and insertion sort is the same, that is n(n - 1)/2. The average performance insertion sort is better. Tested on my i5 cpu with random 30000 integers, selection sort took 1.5s in average, while insertion sort take 0.6s in average.
one way...
$needle = "blah";
$content = file_get_contents('file.txt');
preg_match('~^(.*'.$needle.'.*)$~',$content,$line);
echo $line[1];
though it would probably be better to read it line by line with fopen() and fread() and use strpos()
This Can be Done by Style Property.

Enjoy... Please Note: This works in Higher version of CSS (>3.0).
Basically there are 3 common causes for this problem:
1. You don't have the ADB drivers installed on your computer. Make sure you have the correct ADB drivers for your Android device installed on your PC.
Even if your computer reads your device, You may not have the ADB drivers installed, I recommend that you search and download the correct ADB drivers for your Android device from Google or download an ADB package. If you install an ADB and it doesn't work, try installing another ADB, as it is common that not all ADBs work.
If you're in Windows, when you've installed the correct ADB drivers, maybe the S.O. Run 'Windows Update' to complete the ADB installation.
2. Your device does not have debugger mode enabled. It depends on each version of Android, generally on your Android device you have to go to the configuration menu, then open the developer options and then activate the debugger mode and enable OEM unlocking and USB debugger. ALSO MAKE SURE YOU ALLOW THE DEVELOPER TO SIGN ON YOUR DEVICE
3. Incorrect cable or other physical problems. Sometimes the problems are caused by the data transfer cable, try using other cables.
If your list of words is of substantial length, and you need to do this test many times, it may be worth converting the list to a set and using set intersection to test (with the added benefit that you wil get the actual words that are in both lists):
>>> long_word_list = 'some one long two phrase three about above along after against'
>>> long_word_set = set(long_word_list.split())
>>> set('word along river'.split()) & long_word_set
set(['along'])
I just had this problem too. I closed and opened VS2015 and it "fixed" the issue...
import sys
def progresssbar():
for i in range(100):
time.sleep(1)
sys.stdout.write("%i\r" % i)
progressbar()
NOTE: if you run this in interactive interepter you get extra numbers printed out
With GNU sed
:
sed 's#[^^]#[&]#g;s#\^#\\^#g;s#^#/^#;s#$#$/d#' file1 | sed -f- file2
How it works:
The first sed
produces an output like this:
/^[d][s][f]$/d
/^[s][d][f][s][d]$/d
/^[d][s][f][s][d][f]$/d
Then it is used as a sed
script by the second sed
.
My configuration was like this. I had a QuartzJob , a Service Bean , and Dao . as usual it was configured with LocalSessionFactoryBean (for hibernate) , and SchedulerFactoryBean for Quartz framework. while writing the Quartz job , I by mistake annotated it with @Service , I should not have done that because I was using another strategy to wire the QuartzBean using AutowiringSpringBeanJobFactory extending SpringBeanJobFactory.
So what actually was happening is that due to Quartz Autowire , TX was getting injected to the Job Bean and at the same time Tx Context was set by virtue of @Service annotation and hence the TX was falling out of sync !!
I hope it help to those for whom above solutions really didn't solved the issue. I was using Spring 4.2.5 and Hibernate 4.0.1 ,
I see that in this thread there is a unnecessary suggestion to add @Transactional annotation to the DAO(@Repository) , that is a useless suggestion cause @Repository has all what it needs to have don't have to specially set that @transactional on DAOs , as the DAOs are called from the services which have already being injected by @Trasancational . I hope this might be helpful people who are using Quartz , Spring and Hibernate together.
Since globals are module specific, you can add the following function to all imported modules, and then use it to:
addglobals = lambda x: globals().update(x)
Then all you need to pass on current globals is:
import module
module.addglobals(globals())
I need to know way for converting uri to string and string to uri.
Use toString()
to convert a Uri
to a String
. Use Uri.parse()
to convert a String
to a Uri
.
this code doesn't work
That is not a valid string representation of a Uri
. A Uri
has a scheme, and "/external/images/media/470939"
does not have a scheme.
I'd suggest try the change event? test to see if it has a value if it does then you can continue with your code. jQuery has
.bind("change", function(){ ... });
Or
.change(function(){ ... });
which are equivalents.
for a unique selector change your name attribute to id and then jQuery("#imafile")
or a general jQuery('input[type="file"]')
for all the file inputs
df.filter(df.location.contains('google.com'))
You can use plain SQL in
filter
df.filter("location like '%google.com%'")
or with DataFrame column methods
df.filter(df.location.like('%google.com%'))
You go into ~/.janus
and run:
git submodule add <git@github ...> snipmate-snippets/snippets/
If you need more information about submodules (or git in general) ProGit is pretty useful.
