just add /FORCE as linker flag and you're all set.
for instance, if you're working on CMakeLists.txt. Then add following line:
SET(CMAKE_EXE_LINKER_FLAGS "/FORCE")
First subtract the pivot point (cx,cy)
, then rotate it, then add the point again.
Untested:
POINT rotate_point(float cx,float cy,float angle,POINT p)
{
float s = sin(angle);
float c = cos(angle);
// translate point back to origin:
p.x -= cx;
p.y -= cy;
// rotate point
float xnew = p.x * c - p.y * s;
float ynew = p.x * s + p.y * c;
// translate point back:
p.x = xnew + cx;
p.y = ynew + cy;
return p;
}
Martin Fowler did an interesting blog post last year about non-relational databases starting to gain traction. He mentions:
There is also Google's BigTable which is described as "a sparse, distributed multi-dimensional sorted map".
I have been working with GemStone for a number of years now and the productivity gains is amazing - having the database store your objects directly removes the need to constantly marshall back and forth between tables and objects.
You can do this very simply using LINQ.
Make sure this using is at the top of your C# file:
using System.Linq;
Then use the ToList
extension method.
Example:
IEnumerable<int> enumerable = Enumerable.Range(1, 300);
List<int> asList = enumerable.ToList();
Just increment i
by 3 in each step:
Debug.Assert((theData.Length % 3) == 0); // 'theData' will always be divisible by 3
for (int i = 0; i < theData.Length; i += 3)
{
//grab 3 items at a time and do db insert,
// continue until all items are gone..
string item1 = theData[i+0];
string item2 = theData[i+1];
string item3 = theData[i+2];
// use the items
}
To answer some comments, it is a given that theData.Length
is a multiple of 3 so there is no need to check for theData.Length-2
as an upperbound. That would only mask errors in the preconditions.
When you update the configuration in the php.ini file, you might have to restart apache. Try running apachectl restart
or apache2ctl restart
, or something like that.
Also, in you ini file, make sure you have display_errors = on
, but only in a development environment, never in a production machine.
Also, the strictest error reporting is exactly what you have cited, E_ALL | E_STRICT
. You can find more information on error levels at the php docs.
Use execfile for Python 2:
>>> execfile('C:\\test.py')
Use exec for Python 3

Try with "update tablet set (row='value' where id=0001'), (row='value2' where id=0002'), ...
I recommend using a LifecycleObserver which is part of the Handling Lifecycles with Lifecycle-Aware Components of Android Jetpack.
I want to open and close the Keyboard when the Fragment/Activity appears. Firstly, define two extension functions for the EditText. You can put them anywhere in your project:
fun EditText.showKeyboard() {
requestFocus()
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.showSoftInput(this, InputMethodManager.SHOW_IMPLICIT)
}
fun EditText.hideKeyboard() {
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(this.windowToken, 0)
}
Then define a LifecycleObserver which opens and closes the keyboard when the Activity/Fragment reaches onResume()
or onPause
:
class EditTextKeyboardLifecycleObserver(private val editText: WeakReference<EditText>) :
LifecycleObserver {
@OnLifecycleEvent(Lifecycle.Event.ON_RESUME)
fun openKeyboard() {
editText.get()?.postDelayed({ editText.get()?.showKeyboard() }, 100)
}
@OnLifecycleEvent(Lifecycle.Event.ON_PAUSE)
fun closeKeyboard() {
editText.get()?.hideKeyboard()
}
}
Then add the following line to any of your Fragments/Activities, you can reuse the LifecycleObserver any times. E.g. for a Fragment:
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
// inflate the Fragment layout
lifecycle.addObserver(EditTextKeyboardLifecycleObserver(WeakReference(myEditText)))
// do other stuff and return the view
}

pre-commit
This hook is invoked by git commit, and can be bypassed with --no-verify option. It takes no parameter, and is invoked before obtaining the proposed commit log message and making a commit. Exiting with non-zero status from this script causes the git commit to abort.
I believe this would be somewhere close.
INSERT INTO Files

Something to note, the above runs in SQL Server 2005 and SQL Server 2008 with the data type as varbinary(max)
. It was not tested with image as data type.

Following example uses InputBox method to validate user entry to unhide sheets: Important thing here is to use wrap InputBox variable inside StrPtr so it could be compared to '0' when user chose to click 'x' icon on the InputBox.
Sub unhidesheet()
Dim ws As Worksheet
Dim pw As String
pw = InputBox("Enter Password to Unhide Sheets:", "Unhide Data Sheets")
If StrPtr(pw) = 0 Then
Exit Sub
ElseIf pw = NullString Then
Exit Sub
ElseIf pw = 123456 Then
For Each ws In ThisWorkbook.Worksheets
ws.Visible = xlSheetVisible
Next

In "pydot.py" (located in ...\Anaconda3\Lib\site-packages), replace:
def get_executable_extension():
# type: () -> str
if is_windows():
return '.bat' if is_anacoda() else '.exe'
else:
return ''
with:
def get_executable_extension():
# type: () -> str
if is_windows():
return '.exe'
else:
return ''
There does not seem to be any eason to add ".bat" when the system is "Windows/Anaconda" vs "Windows" and there may be no ".bat" associated with the ".exe". This seems better than adding a ".bat" for every executable pydot calls...
If you are using oracle... STRING

Not PIL, but scipy.misc.imread
might still be interesting:
import scipy.misc
im = scipy.misc.imread('um_000000.png', flatten=False, mode='RGB')
print(im.shape)
gives
(480, 640, 3)
so it is (height, width, channels). So you can iterate over it by
for y in range(im.shape[0]):
for x in range(im.shape[1]):
color = tuple(im[y][x])
r, g, b = color
Much has changed with hooks, e.g. componentWillReceiveProps
turned into useEffect
+useRef
(as shown in this other SO answer), but Props are still Read-Only, so only the caller method should update it.
Since your server already includes the sites-enabled
folder ( notice the include /etc/nginx/sites-enabled/*
line ), then you better use that.
Create a file inside /etc/nginx/sites-available
and call it whatever you want, I'll call it django
since it's a djanog server
sudo touch /etc/nginx/sites-available/django
Then create a symlink that points to it
sudo ln -s /etc/nginx/sites-available/django /etc/nginx/sites-enabled
Then edit that file with whatever file editor you use, vim
or nano
or whatever and create the server inside it
server {
# hostname or ip or multiple separated by spaces
server_name localhost example.com 192.168.1.1; #change to your setting
location / {
root /home/techcee/scrapbook/local/lib/python2.7/site-packages/django/__init__.pyc/;
}
}
Restart or reload nginx settings
sudo service nginx reload
Note I believe that your configuration like this probably won't work yet because you need to pass it to a fastcgi server or something, but at least this is how you could create a valid server
I stumbled over the situation where the list might be empty. In that case:
os.path.join('', *the_list_with_path_components)
Note the first argument, which will not alter the result.
You push your local repository to the remote repository using the git push
command after first establishing a relationship between the two with the git remote add [alias] [url]
command. If you visit your Github repository, it will show you the URL to use for pushing. You'll first enter something like:
git remote add origin [email protected]:username/reponame.git
Unless you started by running git clone
against the remote repository, in which case this step has been done for you already.
And after that, you'll type:
git push origin master
After your first push, you can simply type:
git push
when you want to update the remote repository in the future.
This works fine for me.
f = open(file_path, 'r+', encoding="utf-8")
You can add a third parameter encoding to ensure the encoding type is 'utf-8'
Note: this method works fine in Python3, I did not try it in Python2.7.
To do this you want to loop through each row of your query results and use this info for each of your drop down's options. You should be able to adjust the code below fairly easily to meet your needs.
// Assume $db is a PDO object
$query = $db->query("YOUR QUERY HERE"); // Run your query
echo '<select name="DROP DOWN NAME">'; // Open your drop down box
// Loop through the query results, outputing the options one by one
while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
echo '<option value="'.$row['something'].'">'.$row['something'].'</option>';
}
echo '</select>';// Close your drop down box
I recommend checking out docker-compose. Here's how that would work:
Create a file named, docker-compose.yml that looks like this:
version: '2'
services:
mysql:
image: mariadb:10.1.19
ports:
- 8083:3306
volumes:
- ./mysql:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: wp
Next, run:
$ docker-compose up
Notes:
Now, you can access the mysql console thusly:
$ mysql -P 8083 --protocol=tcp -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 5.5.5-10.1.19-MariaDB-1~jessie mariadb.org binary distribution
Copyright (c) 2000, 2016, Oracle and/or its affiliates. All rights reserved.
Oracle is a registered trademark of Oracle Corporation and/or its
affiliates. Other names may be trademarks of their respective
owners.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
Notes:
You can pass the -d flag to run the mysql/mariadb container in detached/background mode.
The password is "wp" which is defined in the docker-compose.yml file.
Same advice as maniekq but full example with docker-compose.
curl_exec
is necessary. Try CURLOPT_NOBODY
to not download the body. That might be faster.
Pipe to sed -e 's/[\r\n]//g'
to remove both Carriage Returns (\r
) and Line Feeds (\n
) from each text line.
An addition to Stewie's answer. In case when your callback decides whether the propagation should be stopped or not, I found it useful to pass the $event
object to the callback:
<div ng-click="parentHandler($event)">
<div ng-click="childHandler($event)">
</div>
</div>
And then in the callback itself, you can decide whether the propagation of the event should be stopped:
$scope.childHandler = function ($event) {
if (wanna_stop_it()) {
$event.stopPropagation();
}
...
};
You can use docker-compose run
instead of docker-compose up
and tack the arguments on the end. For example:
docker-compose run dperson/samba arg1 arg2 arg3
If you need to connect to other docker containers, use can use --service-ports
option:
docker-compose run --service-ports dperson/samba arg1 arg2 arg3
Hosting a nodejs site through apache can be organized with apache proxy module.
It's better to start nodejs server on localhost with default port 1337
Enable proxy with a command:
sudo a2enmod proxy proxy_http
Do not enable proxying with ProxyRequests until you have secured your server. Open proxy servers are dangerous both to your network and to the Internet at large. Setting ProxyRequests to Off does not disable use of the ProxyPass directive.
Configure /etc/apche2/sites-availables with
<VirtualHost *:80>
ServerAdmin [email protected]
ServerName site.com
ServerAlias www.site.com
ProxyRequests off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location />
ProxyPass http://localhost:1337/
ProxyPassReverse http://localhost:1337/
</Location>
</VirtualHost>
and restart apache2 service.
What is a Servlet?
Servlets run in a servlet container which handles the networking side (e.g. parsing an HTTP request, connection handling etc). One of the best-known open source servlet containers is Tomcat.
In a request/response paradigm, a web server can serve only static pages to the client
Flow of Request
How does the Container know which Servlet client has requested for?
You have information about servlet in this file-
Every servlet in the web app should have an entry into this file
How to "install" Servlets? * Well, the servlet objects are inherited from the library- javax.servlet.* . Tomcat and Spring can be used to utilize these objects to fit the use case.
Ref- Watch this on 1.5x- https://www.youtube.com/watch?v=tkFRGdUgCsE . This has an awesome explanation.
Sould look like:
<td colspan ='4'><img src="\Pics\H.gif" alt="" border='3' height='100' width='100' /></td>
.
<td>
need to be closed with </td>
<img />
is (in most case) an empty tag. The closing tag is replacede by />
instead... like for br's
<br/>
Your html structure is plain worng (sorry), but this will probably turn into a really bad cross-brwoser compatibility. Also, Encapsulate the value of your attributes with quotes and avoid using upercase in tags.
With regard to Brent.Longborough's answer (appering only on page 2 onward), perhaps you need to set the \thispagestyle{} after \begin{document}. I wonder if the letter class is setting the first page style to empty.
I believe the following work in version 0.11 and above. To check the version:
$ ipython --version
It may be worth adding this information to your question.
Solution:
You need to find the file ipython_notebook_config.py
. Depending on your installation process this should be in somewhere like
.config/ipython/profile_default/ipython_notebook_config.py
where .config
is in your home directory.
Once you have located this file find the following lines
# Subset of matplotlib rcParams that should be different for the inline backend.
# c.InlineBackend.rc = {'font.size': 10, 'figure.figsize': (6.0, 4.0), 'figure.facecolor': 'white', 'savefig.dpi': 72, 'figure.subplot.bottom': 0.125, 'figure.edgecolor': 'white'}
Uncomment this line c.InlineBack...
and define your default figsize in the second dictionary entry.
Note that this could be done in a python script (and hence interactively in IPython) using
pylab.rcParams['figure.figsize'] = (10.0, 8.0)
In case the above does not work for you (i.e.: you are working with new SQL or Azure) try the following:
1) drop existing column constraint (if any):
ALTER TABLE [table_name] DROP CONSTRAINT DF_my_constraint
2) create a new one:
ALTER TABLE [table_name] ADD CONSTRAINT DF_my_constraint DEFAULT getdate() FOR column_name;
No you cannot get the MAC address in JavaScript, mainly because the MAC address uniquely identifies the running computer so it would be a security vulnerability.
Now if all you need is a unique identifier, I suggest you create one yourself using some cryptographic algorithm and store it in a cookie.
If you really need to know the MAC address of the computer AND you are developing for internal applications, then I suggest you use an external component to do that: ActiveX for IE, XPCOM for Firefox (installed as an extension).

I wrote a shell script which can let you debug an Android device via Wi-Fi.

#Notice: if unable to connect to [ip]:5555,
#try adb kill-server then try again.
adb shell ip route > addrs.txt
#Case 1:Nexus 7
#192.168.88.0/23 dev wlan0 proto kernel scope link src 192.168.89.48

ip_addrs=$(awk {'if( NF >=9){print $9;}'} addrs.txt)
echo "the device ip address is $ip_addrs"
echo "connecting..."

To update each submodule, you could invoke the following command (at the root of the repository):
git submodule -q foreach git pull -q origin master
You can remove the -q option to follow the whole process.
You'll want to use urllib, requests, beautifulSoup and selenium web driver in your script for different parts of the page, (to name a few).
Sometimes you'll get what you need with just one of these modules.
Sometimes you'll need two, three, or all of these modules.
Sometimes you'll need to switch off the js on your browser.
Sometimes you'll need header info in your script.
No websites can be scraped the same way and no website can be scraped in the same way forever without having to modify your crawler, usually after a few months. But they can all be scraped! Where there's a will there's a way for sure.
If you need scraped data continuously into the future just scrape everything you need and store it in .dat files with pickle.
Just keep searching how to try what with these modules and copying and pasting your errors into the Google.
This can be done with a HTTP Post request to the server:
HttpClient http = AndroidHttpClient.newInstance("MyApp");
HttpPost method = new HttpPost("http://url-to-server");
method.setEntity(new FileEntity(new File("path-to-file"), "application/octet-stream"));
HttpResponse response = http.execute(method);
use request.getContextPath()
instead of ${pageContext.request.contextPath}
in JSP expression language.
<%
String contextPath = request.getContextPath();
%>
out.println(contextPath);
output: willPrintMyProjectcontextPath
To get a list of tables for the current database in DB2 -->
Connect to the database:
db2 connect to DATABASENAME user USER using PASSWORD
Run this query:
db2 LIST TABLES
This is the equivalent of SHOW TABLES in MySQL.
You may need to execute 'set schema myschema' to the correct schema before you run the list tables command. By default upon login your schema is the same as your username - which often won't contain any tables. You can use 'values current schema' to check what schema you're currently set to.
The main differnece is when you say ClassName obj = null; you are just creating an object for that class. It's not an instance of that class.
This statement will just allot memory for the static meber variables, not for the normal member variables.
But when you say ClassName obj = new ClassName(); you are creating an instance of the class. This staement will allot memory all member variables.
If you need to delete based on a list, you can use IN
:
DELETE FROM your_table
WHERE id IN (value1, value2, ...);
If you need to delete based on the result of a query, you can also use IN
:
DELETE FROM your_table
WHERE id IN (select aColumn from ...);
(Notice that the subquery must return only one column)
If you need to delete based on a range of values, either you use BETWEEN
or you use inequalities:
DELETE FROM your_table
WHERE id BETWEEN bottom_value AND top_value;
or
DELETE FROM your_table
WHERE id >= a_value AND id <= another_value;
$e=error_get_last();
if($e['message']!==''){
// An error function
}
error_get_last(); - return the last error that occurred
The linefeed character \n
is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n
instead, then it'll both see the line-break with only \n
and \r\n
, I've never had any problems using it.
Also, you should look into using a StringBuilder
instead of concatenating the String
in the while-loop at BookCatalog.toString()
, it is a lot more effective. For instance:
public String toString() {
BookNode current = front;
StringBuilder sb = new StringBuilder();
while (current!=null){
sb.append(current.getData().toString()+"\r\n ");
current = current.getNext();
}
return sb.toString();
}
What if you just wrap your code into function?
So this:
cd ~/documents
mkdir test
echo "useless script" > about.txt
Becomes this:
CommentedOutBlock() {
cd ~/documents
mkdir test
echo "useless script" > about.txt
}
It seems problem is not in JDK bug 6602600 ( it was solved at 2010-05-22), but in incorrect call of sleep(10) in circle. Addition note, that the main Thread must give directly CHANCE to other threads to realize thier tasks by invoke SLEEP(0) in EVERY branch of outer circle. It is better, I think, to use Thread.yield() instead of Thread.sleep(0)
The result corrected part of previous problem code is such like this:
.......................
........................
Thread.yield();
if (i % 1000== 0) {
System.out.println(i + "/" + counter.get()+ "/"+service.toString());
}
//
// while (i > counter.get()) {
// Thread.sleep(10);
// }
It works correctly with amount of outer counter up to 150 000 000 tested circles.
This will do it if you only want the first "B" value, you can sub a cell address for "B" if you want to make it more generic.
=INDEX(A2:A6,SUMPRODUCT(MATCH(TRUE,(B2:B6)="B",0)),1)
To use this based on two columns, just concatenate inside the match:
=INDEX(A2:A6,SUMPRODUCT(MATCH(TRUE,(A2:A6&B2:B6)=("3"&"B"),0)),1)
Sample Html:
<section id="parent">
<article class="child"></article>
<article class="child"></article>
</section>
Js:
jQuery.fn.redraw = function() {
return this.hide(0,function() {$(this).show(100);});
// hide immediately and show with 100ms duration
};
call function:
//<==bad idea$('article.child').redraw();
$('#parent').redraw();
To stage modified and deleted files
git add -u
Working! You can save image by using FileSystemStorage. check the example below
def upload_pic(request):
if request.method == 'POST' and request.FILES['photo']:
photo = request.FILES['photo']
name = request.FILES['photo'].name
fs = FileSystemStorage()
##### you can update file saving location too by adding line below #####
fs.base_location = fs.base_location+'/company_coverphotos'
##################
filename = fs.save(name, photo)
uploaded_file_url = fs.url(filename)+'/company_coverphotos'
Profile.objects.filter(user=request.user).update(photo=photo)
Put your script after the completion of body tag...it works...
This is not a new answer, but it helped me to understand the different aspects of the answers above (and it is too much for a comment).

though in this case the defaults are smart enough to work (it looks for non-alphanumeric characters to split on).
separate(data = df, col = FOO, into = c("left", "right"))
In rare cases (e.g., after a heavy transaction is commited) a running CHECKPOINT system process holding a FILE lock on the database file prevents transition to MULTI_USER mode.
If this helps: I've had the same problem and simply wrote a generic function that takes an array and returns an ArrayList of the same type with the same contents:
public static <T> ArrayList<T> ArrayToArrayList(T[] array) {
ArrayList<T> list = new ArrayList<T>();
for(T elmt : array) list.add(elmt);
return list;
}

Try issuing this multiple times. I hope you are looking for the same output.
How about std::remove()
instead:
#include <algorithm>
...
vec.erase(std::remove(vec.begin(), vec.end(), 8), vec.end());
This combination is also known as the erase-remove idiom.
A simple, although awk-less solution in bash:
while IFS=, read -r a a a b; do echo "$a"; done <inputfile
It works faster for small files (<100 lines) then awk as it uses less resources (avoids calling the expensive fork
and execve
system calls).
EDIT from Ed Morton (sorry for hi-jacking the answer, I don't know if there's a better way to address this):
To put to rest the myth that shell will run faster than awk for small files:
$ wc -l file
99 file
$ time while IFS=, read -r a a a b; do echo "$a"; done <file >/dev/null
real 0m0.016s
user 0m0.000s
sys 0m0.015s
$ time awk -F, '{print $3}' file >/dev/null
real 0m0.016s
user 0m0.000s
sys 0m0.015s
I expect if you get a REALY small enough file then you will see the shell script run in a fraction of a blink of an eye faster than the awk script but who cares?
And if you don't believe that it's harder to write robust shell scripts than awk scripts, look at this bug in the shell script you posted:
$ cat file
a,b,-e,d
$ cut -d, -f3 file
-e
$ awk -F, '{print $3}' file
-e
$ while IFS=, read -r a a a b; do echo "$a"; done <file

Upgrading my scikit-learn from 0.19.1 to 0.19.2 in anaconda installed on Ubuntu on Google VM instance:
First, check existing available packages with versions by using:
conda list
It will show different packages and their installed versions in the output. Here check for scikit-learn. e.g. for me, the output was:
scikit-learn 0.19.1 py36hedc7406_0
Now I want to Upgrade to 0.19.2 July 2018 release i.e. latest available version.
conda config --append channels conda-forge
conda install scikit-learn=0.19.2
As you are trying to upgrade to 0.17 version try the following command:
conda install scikit-learn=0.17
Now check the required version of the scikit-learn is installed correctly or not by using:
conda list
For me the Output was:
scikit-learn 0.19.2 py36_blas_openblasha84fab4_201 [blas_openblas] conda-forge
I tried following commands:
!conda update conda
!pip install -U scikit-learn
It will install the required packages also will show in the conda list
but if you try to import that package it will not work.
On the website http://scikit-learn.org/stable/install.html it is mentioned as: Warning To upgrade or uninstall scikit-learn installed with Anaconda or conda you should not use the pip.
One-liner solution
import pandas as pd

Using Google Collections, you could use the following methods in the Lists class
import com.google.common.collect.Lists;
// ...
List<String> strings = Lists.newArrayList();
List<Integer> integers = Lists.newLinkedList();
There are overloads for varargs initialization and initialising from an Iterable<T>
.
The advantage of these methods is that you don't need to specify the generic parameter explicitly as you would with the constructor - the compiler will infer it from the type of the variable.
You can do it in a single command:
git fetch --all && git reset --hard origin/master
Or in a pair of commands:
git fetch --all
git reset --hard origin/master
Note than you will lose ALL your local changes
you can use this one.
<div id="test"></div>
you java script code should be like that.
setInterval(function(){
$('#test').load('test.php');
},5000);
Another important difference is that Hashtable is thread safe. Hashtable has built-in multiple reader/single writer (MR/SW) thread safety which means Hashtable allows ONE writer together with multiple readers without locking.
In the case of Dictionary there is no thread safety; if you need thread safety you must implement your own synchronization.
To elaborate further:
Hashtable provides some thread-safety through the
Synchronized
property, which returns a thread-safe wrapper around the collection. The wrapper works by locking the entire collection on every add or remove operation. Therefore, each thread that is attempting to access the collection must wait for its turn to take the one lock. This is not scalable and can cause significant performance degradation for large collections. Also, the design is not completely protected from race conditions.The .NET Framework 2.0 collection classes like
List<T>, Dictionary<TKey, TValue>
, etc. do not provide any thread synchronization; user code must provide all synchronization when items are added or removed on multiple threads concurrently
If you need type safety as well thread safety, use concurrent collections classes in the .NET Framework. Further reading here.
An additional difference is that when we add the multiple entries in Dictionary, the order in which the entries are added is maintained. When we retrieve the items from Dictionary we will get the records in the same order we have inserted them. Whereas Hashtable doesn't preserve the insertion order.
private boolean containsIgnoreCase(List<String> list, String soughtFor) {
for (String current : list) {
if (current.equalsIgnoreCase(soughtFor)) {
return true;
}
}
return false;
}
It's far from pretty, but you could create a script or an alias that does something like this:
for c in $(git for-each-ref refs/tags/ --format='%(refname)'); do echo $c; git show --quiet "$c"; echo; done
If you want to select the columns from First Table "which are also present in Second table, then in this case you can also use EXCEPT
. In this case, column names can be different as well but data type should be same.
Example:
select ID, FName
from FirstTable
EXCEPT
select ID, SName
from SecondTable
I'm guessing you didn't run this command after the commit failed so just actually run this to create the remote :
git remote add origin https://github.com/VijayNew/NewExample.git
And the commit failed because you need to git add
some files you want to track.
This type of warnings are usually flagged because of the request HTTP headers. Specifically the Accept request header. The MDN documentation for HTTP headers states
The Accept request HTTP header advertises which content types, expressed as MIME types, the client is able to understand. Using content negotiation, the server then selects one of the proposals, uses it and informs the client of its choice with the Content-Type response header. Browsers set adequate values for this header depending of the context where the request is done....
application/json is probably not on the list of MIME types in the Accept header sent by the browser hence the warning.
Solution
Custom HTTP headers can only be sent programmatically via XMLHttpRequest or any of the js library wrappers implementing it.
SELECT text

I suggest you also (I prefer this) the string.concat method
The accepted answer gave two locations:
here
C:\Documents and Settings\Administrator\Local Settings\Temp\VWDWebCache
and possibly here
C:\Documents and Settings\Administrator\Local Settings\Application Data\Microsoft\WebsiteCache
Did you try those?
Edited to add
On my Windows Vista machine, it's located in
%Temp%\VWDWebCache
and in
%LocalAppData%\Microsoft\WebsiteCache
From your additional information (regarding team edition) this comes from Clear Client TFS Cache:
Clear Client TFS Cache
Visual Studio and Team Explorer provide a caching mechanism which can get out of sync. If I have multiple instances of a single TFS which can be connected to from a single Visual Studio client, that client can become confused.

Loop through divs every 10 seconds.

.show('fast'); // and show it
counter++;
}; // function to loop through divs and show correct div
showDiv(); // show first div
setInterval(function () {
showDiv(); // show next div
}, 10 * 1000); // do this every 10 seconds
});
static variables are stored in the heap
You can do it with:
UPDATE mytable SET Total = Pieces * Price;
Use either of the two commands below. Everything must be in uppercase. The table name must be wrapped in quotation marks:
--SEE THE CONSTRAINTS ON A TABLE
SELECT COLUMN_NAME, CONSTRAINT_NAME FROM USER_CONS_COLUMNS WHERE TABLE_NAME = 'TBL_CUSTOMER';
--OR FOR LESS DETAIL
SELECT CONSTRAINT_NAME FROM USER_CONSTRAINTS WHERE TABLE_NAME = 'TBL_CUSTOMER';
I would just do:
private static Timer timer;
private static void Main()
{
timer = new Timer(_ => OnCallBack(), null, 1000 * 10,Timeout.Infinite); //in 10 seconds
Console.ReadLine();
}
private static void OnCallBack()
{
timer.Dispose();
Thread.Sleep(3000); //doing some long operation
timer = new Timer(_ => OnCallBack(), null, 1000 * 10,Timeout.Infinite); //in 10 seconds
}
And ignore the period parameter, since you're attempting to control the periodicy yourself.
Your original code is running as fast as possible, since you keep specifying 0
for the dueTime
parameter. From Timer.Change
:
If dueTime is zero (0), the callback method is invoked immediately.
I have another way to do this... suppose you swap out your message converter to String for your RestTemplate, then you can receive raw JSON. Using the raw JSON, you can then map it into your Generic Collection using a Jackson Object Mapper. Here's how:
Swap out the message converter:
List<HttpMessageConverter<?>> oldConverters = new ArrayList<HttpMessageConverter<?>>();
oldConverters.addAll(template.getMessageConverters());
List<HttpMessageConverter<?>> stringConverter = new ArrayList<HttpMessageConverter<?>>();
stringConverter.add(new StringHttpMessageConverter());
template.setMessageConverters(stringConverter);
Then get your JSON response like this:
ResponseEntity<String> response = template.exchange(uri, HttpMethod.GET, null, String.class);
Process the response like this:
String body = null;
List<T> result = new ArrayList<T>();
ObjectMapper mapper = new ObjectMapper();
if (response.hasBody()) {
body = items.getBody();
try {
result = mapper.readValue(body, mapper.getTypeFactory().constructCollectionType(List.class, clazz));
} catch (Exception e) {
e.printStackTrace();
} finally {
template.setMessageConverters(oldConverters);
}

There is Javascript function isNaN which will do that.
isNaN(90)

so you can check numeric by
!isNaN(90)

Your array is occupying roughly 8 GB of memory (1,000 x 1,000,000 x sizeof(double) bytes). That might be a factor in your problem. It is a global variable rather than a stack variable, so you may be OK, but you're pushing limits here.
Writing that much data to a file is going to take a while.
You don't check that the file was opened successfully, which could be a source of trouble, too (if it did fail, a segmentation fault is very likely).
You really should introduce some named constants for 1,000 and 1,000,000; what do they represent?
You should also write a function to do the calculation; you could use an inline
function in C99 or later (or C++). The repetition in the code is excruciating to behold.
You should also use C99 notation for main()
, with the explicit return type (and preferably void
for the argument list when you are not using argc
or argv
):
int main(void)
Out of idle curiosity, I took a copy of your code, changed all occurrences of 1000 to ROWS, all occurrences of 1000000 to COLS, and then created enum { ROWS = 1000, COLS = 10000 };
(thereby reducing the problem size by a factor of 100). I made a few minor changes so it would compile cleanly under my preferred set of compilation options (nothing serious: static
in front of the functions, and the main array; file
becomes a local to main
; error check the fopen()
, etc.).
I then created a second copy and created an inline function to do the repeated calculation, (and a second one to do subscript calculations). This means that the monstrous expression is only written out once — which is highly desirable as it ensure consistency.
#include <stdio.h>
#define lambda 2.0
#define g 1.0
#define F0 1.0
#define h 0.1
#define e 0.00001
enum { ROWS = 1000, COLS = 10000 };
static double F[ROWS][COLS];
static void Inicio(double D[ROWS][COLS])
{
for (int i = 399; i < 600; i++) // Magic numbers!!
D[i][0] = F0;
}
enum { R = ROWS - 1 };
static inline int ko(int k, int n)
{
int rv = k + n;
if (rv >= R)
rv -= R;
else if (rv < 0)
rv += R;
return(rv);
}
static inline void calculate_value(int i, int k, double A[ROWS][COLS])
{
int ks2 = ko(k, -2);
int ks1 = ko(k, -1);
int kp1 = ko(k, +1);
int kp2 = ko(k, +2);
A[k][i] = A[k][i-1]
+ e/(h*h*h*h) * g*g * (A[kp2][i-1] - 4.0*A[kp1][i-1] + 6.0*A[k][i-1] - 4.0*A[ks1][i-1] + A[ks2][i-1])
+ 2.0*g*e/(h*h) * (A[kp1][i-1] - 2*A[k][i-1] + A[ks1][i-1])
+ e * A[k][i-1] * (lambda - A[k][i-1] * A[k][i-1]);
}
static void Iteration(double A[ROWS][COLS])
{
for (int i = 1; i < COLS; i++)
{
for (int k = 0; k < R; k++)
calculate_value(i, k, A);
A[999][i] = A[0][i];
}
}
int main(void)
{
FILE *file = fopen("P2.txt","wt");
if (file == 0)
return(1);
Inicio(F);
Iteration(F);
for (int i = 0; i < COLS; i++)
{
for (int j = 0; j < ROWS; j++)
{
fprintf(file,"%lf \t %.4f \t %lf\n", 1.0*j/10.0, 1.0*i, F[j][i]);
}
}
fclose(file);
return(0);
}
This program writes to P2.txt
instead of P1.txt
. I ran both programs and compared the output files; the output was identical. When I ran the programs on a mostly idle machine (MacBook Pro, 2.3 GHz Intel Core i7, 16 GiB 1333 MHz RAM, Mac OS X 10.7.5, GCC 4.7.1), I got reasonably but not wholly consistent timing:

However, almost all that time is spent on disk I/O. I reduced the disk I/O to just the very last row of data, so the outer I/O for
loop became:
for (int i = COLS - 1; i < COLS; i++)
the timings were vastly reduced and very much more consistent:

The simplification in the code from having the ghastly expression written out just once is very beneficial, it seems to me. I'd certainly far rather have to maintain that program than the original.
If you want to import a module, if it exists, and ignore importing it, if that module does not exists, you can use the below code:
try:
import a_module
except ImportError:
pass
#rest of your code
If you avoid writing the pass statement and continue writing the rest of your code, a IndentationError would be raised, since the lines after opening the except block are not indented
Only thing that comes even close is the :contains
pseudo class in CSS3, but that only selects textual content, not tags or elements, so you're out of luck.
A simpler way to select a parent with specific children in jQuery can be written as (with :has()

I had same problem and finally found my mistake :) I used this command for compiling and it worked correctly:
javac -cp "/home/omidmohebbi/AAAATest/jars/core-1.7.jar:/home/omidmohebbi/AAAATest/jars/javase-1.7.jar:/home/omidmohebbi/AAAATest/jars/qrgen-1.2.jar" qrcode.java
But this command did not work for me (I could not find or load the main class, qrcode

To check on elasticsearch cluster health you need to use
curl localhost:9200/_cat/health
More on the cat APIs here.
I usually use elasticsearch-head plugin to visualize that.
You can find it's github project here.
It's easy to install sudo $ES_HOME/bin/plugin -i mobz/elasticsearch-head
and then you can open localhost:9200/_plugin/head/
in your web brower.
You should have something that looks like this :
Use the files
filelist of the element instead of val()
$("input[type=file]").on('change',function(){
alert(this.files[0].name);
});
It is purely a string:
startInfo.Arguments = "-sk server -sky exchange -pe -n CN=localhost -ir LocalMachine -is Root -ic MyCA.cer -sr LocalMachine -ss My MyAdHocTestCert.cer"
Of course, when arguments contain whitespaces you'll have to escape them using \" \", like:
"... -ss \"My MyAdHocTestCert.cer\""
See MSDN for this.
I think the Apache Commons Lang library's StringEscapeUtils.unescapeHtml3()
and unescapeHtml4()
methods are what you are looking for. See https://commons.apache.org/proper/commons-text/javadocs/api-release/org/apache/commons/text/StringEscapeUtils.html.
I'm not sure you have gotten past this yet, but I had to work on something very similar today and I got your fiddle working like you are asking, basically what I did was make another table row under it, and then used the accordion control. I tried using just collapse but could not get it working and saw an example somewhere on SO that used accordion.
Here's your updated fiddle: http://jsfiddle.net/whytheday/2Dj7Y/11/
Since I need to post code here is what each collapsible "section" should look like ->
<tr data-toggle="collapse" data-target="#demo1" class="accordion-toggle">
<td>1</td>
<td>05 May 2013</td>
<td>Credit Account</td>
<td class="text-success">$150.00</td>
<td class="text-error"></td>
<td class="text-success">$150.00</td>
</tr>
<tr>
<td colspan="6" class="hiddenRow">
<div class="accordion-body collapse" id="demo1">Demo1</div>
</td>
</tr>
regarding Kevin answer to write in a folder tmp
, it should be like this:
with open('./tmp/metadata.pdf', 'wb') as f:
f.write(response.content)
he forgot .
before the address and of-course your folder tmp
should have been created already
Try:
string value = ConfigurationManager.AppSettings[key];
For more details check: Reading Keys from App.Config
You can use
str1.compareTo(str2);
If str1 is lexicographically less than str2, a negative number
will be returned, 0
if equal or a positive number
if str1 is greater.
E.g.,
"a".compareTo("b"); // returns a negative number, here -1
"a".compareTo("a"); // returns 0
"b".compareTo("a"); // returns a positive number, here 1
"b".compareTo(null); // throws java.lang.NullPointerException
You can also configure m2e to use HTTP instead of HTTPS

I am not shure whether or not it is "neater", but from a performance-standpoint it probably won't matter much.
Here is an extension of Roberto14's answer that does the following:
THIS WILL ONLY ALLOW IMAGES
Checks if FileReader is available and falls back to extension checking if it is not available.
Gives an error alert if not an image
If it is an image it loads a preview
** You should still do server side validation, this is more a convenience for the end user than anything else. But it is handy!
<form id="myform">
<input type="file" id="myimage" onchange="readURL(this)" />
<img id="preview" src="#" alt="Image Preview" />
</form>
<script>
function readURL(input) {
if (window.FileReader && window.Blob) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
var img = new Image();
img.onload = function() {
var preview = document.getElementById('preview');
preview.src = e.target.result;
};
img.onerror = function() {
alert('error');
input.value = '';
};
img.src = e.target.result;
}
reader.readAsDataURL(input.files[0]);
}
}
else {
var ext = input.value.split('.');
ext = ext[ext.length-1].toLowerCase();
var arrayExtensions = ['jpg' , 'jpeg', 'png', 'bmp', 'gif'];
if (arrayExtensions.lastIndexOf(ext) == -1) {
alert('error');
input.value = '';
}
else {
var preview = document.getElementById('preview');
preview.setAttribute('alt', 'Browser does not support preview.');
}
}
}
</script>
Modify your HTML like this:
<table border="0" cellpadding="0" cellspacing="0">
<thead>
<tr><td>1</td><td>2</td><td>3</td></tr>
</thead>
<tbody>
<tr><td>a</td><td>b></td><td>c</td></tr>
<tr class='odd'><td>x</td><td>y</td><td>z</td></tr>
</tbody>
</table>
(I added border="0" cellpadding="0" cellspacing="0"
)
In CSS, you could do the following:
table {
border-collapse: collapse;
}
Thanks for the answers above, that helped me a lot :-) But for those (like me) forced to still support Android 1.5 we can use java reflection for backward compatible:
Configuration conf = getResources().getConfiguration();
int screenLayout = 1; // application default behavior
try {
Field field = conf.getClass().getDeclaredField("screenLayout");
screenLayout = field.getInt(conf);
} catch (Exception e) {
// NoSuchFieldException or related stuff
}
// Configuration.SCREENLAYOUT_SIZE_MASK == 15
int screenType = screenLayout & 15;
// Configuration.SCREENLAYOUT_SIZE_SMALL == 1
// Configuration.SCREENLAYOUT_SIZE_NORMAL == 2
// Configuration.SCREENLAYOUT_SIZE_LARGE == 3
// Configuration.SCREENLAYOUT_SIZE_XLARGE == 4
if (screenType == 1) {
...
} else if (screenType == 2) {
...
} else if (screenType == 3) {
...
} else if (screenType == 4) {
...
} else { // undefined
...
}
we can also use lattice library
library(lattice)
x <- seq(-2,2,0.05)
y1 <- pnorm(x)
y2 <- pnorm(x,1,1)
xyplot(y1 + y2 ~ x, ylab = "y1 and y2", type = "l", auto.key = list(points = FALSE,lines = TRUE))
For specific colors
xyplot(y1 + y2 ~ x,ylab = "y1 and y2", type = "l", auto.key = list(points = F,lines = T), par.settings = list(superpose.line = list(col = c("red","green"))))
Have you tested the speed?
i.e. Have you created a sample set of data and profiled it? It may not be as bad as you think.
This might also be something you could spawn off into a separate thread and give the illusion of speed!
Why not use a library function to validate the ip address?
>>> ip="241.1.1.112343434"
>>> socket.inet_aton(ip)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
socket.error: illegal IP address string passed to inet_aton
you can write a function which converts from unsigned long to str, similar to ltostr library function.
char *ultostr(unsigned long value, char *ptr, int base)
{
unsigned long t = 0, res = 0;
unsigned long tmp = value;
int count = 0;
if (NULL == ptr)
{
return NULL;
}
if (tmp == 0)
{
count++;
}
while(tmp > 0)
{
tmp = tmp/base;
count++;
}
ptr += count;
*ptr = '\0';
do
{
res = value - base * (t = value / base);
if (res < 10)
{
* -- ptr = '0' + res;
}
else if ((res >= 10) && (res < 16))
{
* --ptr = 'A' - 10 + res;
}
} while ((value = t) != 0);
return(ptr);
}
you can refer to my blog here which explains implementation and usage with example.
Doing it this way has always worked for me, I hope this helps.
var ddl = $("#dropListBuilding");
for (k = 0; k < buildings.length; k++)
ddl.append("<option value='" + buildings[k]+ "'>" + buildings[k] + "</option>");
I'm not certain what's wrong with your code specifically, but I use this function I found online (URL in the comments) for checking if a file exists:
Private Function File_Exists(ByVal sPathName As String, Optional Directory As Boolean) As Boolean
'Code from internet: http://vbadud.blogspot.com/2007/04/vba-function-to-check-file-existence.html
'Returns True if the passed sPathName exist
'Otherwise returns False
On Error Resume Next
If sPathName <> "" Then
If IsMissing(Directory) Or Directory = False Then
File_Exists = (Dir$(sPathName) <> "")
Else
File_Exists = (Dir$(sPathName, vbDirectory) <> "")
End If
End If
End Function
# setting ----------------
commonMode=false
if [[ $something == 'COMMON' ]]; then
commonMode=true
fi
# using ----------------
if $commonMode; then
echo 'YES, Common Mode'
else
echo 'NO, no Common Mode'
fi
$commonMode && echo 'commonMode is ON ++++++'
$commonMode || echo 'commonMode is OFF xxxxxx'
You cannot invoke JavaScript functions in standard HTML attributes other than onXXX
. Just assign it during window onload.
<script type="text/javascript">
window.onload = function() {
document.myform.action = get_action();
}
function get_action() {
return form_action;
}
</script>
<form name="myform">
...
</form>
You see that I've given the form a name
, so that it's easily accessible in document
.
Alternatively, you can also do it during submit
event:
<script type="text/javascript">
function get_action(form) {
form.action = form_action;
}
</script>
<form onsubmit="get_action(this);">
...
</form>
Please Try with this. I hope it will work for you.

Building on the solution by MoonScript, you could try this instead:

The benefit is that since it's a lower level solution, it will enable CORS (to the extent possible) on IE 8/9 with other frameworks, not just with jQuery. I've had success using it with AngularJS, as well as jQuery 1.x and 2.x.
Based on @lijat, here is a simplified implementation. In my spring-based application I simply load this as a bean.
public static void configureLog4jFromSystemProperties()
{
final String LOGGER_PREFIX = "log4j.logger.";
for(String propertyName : System.getProperties().stringPropertyNames())
{
if (propertyName.startsWith(LOGGER_PREFIX)) {
String loggerName = propertyName.substring(LOGGER_PREFIX.length());
String levelName = System.getProperty(propertyName, "");
Level level = Level.toLevel(levelName); // defaults to DEBUG
if (!"".equals(levelName) && !levelName.toUpperCase().equals(level.toString())) {
logger.error("Skipping unrecognized log4j log level " + levelName + ": -D" + propertyName + "=" + levelName);
continue;
}
logger.info("Setting " + loggerName + " => " + level.toString());
Logger.getLogger(loggerName).setLevel(level);
}
}
}
In Python 2.x this is not guaranteed as it is possible for True
and False
to be reassigned. However, even if this happens, boolean True and boolean False are still properly returned for comparisons.
In Python 3.x True
and False
are keywords and will always be equal to 1
and 0
.
Under normal circumstances in Python 2, and always in Python 3:
False
object is of type bool
which is a subclass of int
:
object
|
int
|
bool
It is the only reason why in your example, ['zero', 'one'][False]
does work. It would not work with an object which is not a subclass of integer, because list indexing only works with integers, or objects that define a __index__
method (thanks mark-dickinson).
Edit:
It is true of the current python version, and of that of Python 3. The docs for python 2 and the docs for Python 3 both say:
There are two types of integers: [...] Integers (int) [...] Booleans (bool)
and in the boolean subsection:
Booleans: These represent the truth values False and True [...] Boolean values behave like the values 0 and 1, respectively, in almost all contexts, the exception being that when converted to a string, the strings "False" or "True" are returned, respectively.
There is also, for Python 2:
In numeric contexts (for example when used as the argument to an arithmetic operator), they [False and True] behave like the integers 0 and 1, respectively.
So booleans are explicitly considered as integers in Python 2 and 3.
So you're safe until Python 4 comes along. ;-)
get_current_user_id()
will return the current user id (an integer), or will return 0 if the user is not logged in.
if (get_current_user_id()) {
// display navbar here
}
More details here get_current_user_id().
For all those looking for programming parlance, here is how it works. Internal implementation of advanced hashtables has many intricacies and optimisations for storage allocation/deallocation and search, but top-level idea will be very much the same.
(void) addValue : (object) value
{
int bucket = calculate_bucket_from_val(value);
if (bucket)
{
//do nothing, just overwrite
}
else //create bucket
{
create_extra_space_for_bucket();
}
put_value_into_bucket(bucket,value);
}
(bool) exists : (object) value
{
int bucket = calculate_bucket_from_val(value);
return bucket;
}
where calculate_bucket_from_val()
is the hashing function where all the uniqueness magic must happen.
The rule of thumb is: For a given value to be inserted, bucket must be UNIQUE & DERIVABLE FROM THE VALUE that it is supposed to STORE.
Bucket is any space where the values are stored - for here I have kept it int as an array index, but it maybe a memory location as well.
Add some transition effect to it if you like:
http://jsbin.com/boreme/17/edit?html,css,js
.clearHeader {
height:50px;
background:lightblue;
position:fixed;
top:0;
left:0;
width:100%;
-webkit-transition: background 2s; /* For Safari 3.1 to 6.0 */
transition: background 2s;
}
.clearHeader.darkHeader {
background:#000;
}
With your code, the vue.js
is trying to access the moment()
method from its scope.
Hence you should use a method like this:
methods: {
moment: function () {
return moment();
}
},
If you want to pass a date to the moment.js
, I suggest to use filters:
filters: {
moment: function (date) {
return moment(date).format('MMMM Do YYYY, h:mm:ss a');
}
}
<span>{{ date | moment }}</span>
#Single line

multi-line

Try this:
CONCATENATE(""""; B2 ;"""")
@widor provided a nice solution alternative too - integrated with mine:
CONCATENATE(char(34); B2 ;char(34))
This one seems to imply that 030 and 031 are up and down triangles.
(As bobince pointed out, this doesn't seem to be an ASCII standard)
There is no such thing as a byte or short literal. You need to cast to short using (short)100
I can confirm that mp4 just will not work in the video tag. No matter how much you try to mess with the type tag and the codec and the mime types from the server.
Crazy, because for the same exact video, on the same test page, the old embed tag for an mp4 works just fine in firefox. I spent all yesterday messing with this. Firefox is like IE all of a sudden, hours and hours of time, not billable. Yay.
Speaking of IE, it fails FAR MORE gracefully on this. When it can't match up the format it falls to the content between the tags, so it is possible to just put video around object around embed and everything works great. Firefox, nope, despite failing, it puts up the poster image (greyed out so that isn't even useful as a fallback) with an error message smack in the middle. So now the options are put in browser recognition code (meaning we've gained nothing on embedding videos in the last ten years) or ditch html5.
Have you tried something like this?
sqlplus username/password@database < "EXECUTE some_proc /"
Seems like in UNIX you can do:
sqlplus username/password@database <<EOF
EXECUTE some_proc;
EXIT;
EOF
But I'm not sure what the windows equivalent of that would be.
item
is most likely a string in your code; the string indices are the ones in the square brackets, e.g., gravatar_id
. So I'd first check your data
variable to see what you received there; I guess that data
is a list of strings (or at least a list containing at least one string) while it should be a list of dictionaries.
A working example.
DECLARE @TableName AS VARCHAR(100)
SELECT @TableName = 'YourTableName'
EXECUTE ('SELECT * INTO #TEMP FROM ' + @TableName +'; SELECT * FROM #TEMP;')
Second solution with accessible temp table
DECLARE @TableName AS VARCHAR(100)
SELECT @TableName = 'YOUR_TABLE_NAME'
EXECUTE ('CREATE VIEW vTemp AS
SELECT *
FROM ' + @TableName)
SELECT * INTO #TEMP FROM vTemp
--DROP THE VIEW HERE
DROP VIEW vTemp
/*START USING TEMP TABLE
************************/
--EX:
SELECT * FROM #TEMP
--DROP YOUR TEMP TABLE HERE
DROP TABLE #TEMP
@Justin Pollard xml code works really good. As a side note you can add a ripple effect with the following xml lines.
<item>
<ripple
xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?android:colorControlHighlight" >
<item android:id="@android:id/mask">
<shape android:shape="oval" >
<solid android:color="#FFBB00" />
</shape>
</item>
<item>
<shape android:shape="oval" >
<solid android:color="@color/ColorPrimary" />
</shape>
</item>
</ripple>
</item>
Use this method and pass your array in parameter
Collections.shuffle(arrayList);
This method return void so it will not give you a new list but as we know that array is passed as a reference type in Java so it will shuffle your array and save shuffled values in it. That's why you don't need any return type.
You can now use arraylist which is shuffled.
Its possible to make Android device behave as an NFC Tag. Such a behaviour is called Card Emulation.
Enter the formula =ROW()

If you want 1001, 1002 etc just enter =1000+ROW()
This solution works like a charm (updated in 2017 to honor that log_format needs to be in the http part of the nginx config):
log_format postdata $request_body;
server {
# (...)
location = /post.php {
access_log /var/log/nginx/postdata.log postdata;
fastcgi_pass php_cgi;
}
}
I think the trick is making nginx believe that you will call a cgi script.

Vim has a branch operator \&
that is useful when searching for a line containing a set of words, in any order. Moreover, extending the set of required words is trivial.
For example,
/.*jack\&.*james
will match a line containing jack
and james
, in any order.
See this answer for more information on usage. I am not aware of any other regex flavor that implements branching; the operator is not even documented on the Regular Expression wikipedia entry.
This is what i used to do on my android projects..
In Android Studio we can do similar operation by, Ctrl+Shift+F to find from whole project (Command+Shift+F in MacOs) and Ctrl+Shift+R to Replace ((Command+Shift+R in MacOs))
It looks easier for me to clear all TabPages add add those wished:
PropertyTabControl.TabPages.Clear();
PropertyTabControl.TabPages.Add(AspectTabPage);
PropertyTabControl.TabPages.Add(WerkstattTabPage);
or
PropertyTabControl.TabPages.Clear();
PropertyTabControl.TabPages.Add(TerminTabPage);
You can create a list of lists
public class MultiDimList: List<List<string>> { }
or a Dictionary of key-accessible Lists
public class MultiDimDictList: Dictionary<string, List<int>> { }
MultiDimDictList myDicList = new MultiDimDictList ();
myDicList.Add("ages", new List<int>());
myDicList.Add("Salaries", new List<int>());
myDicList.Add("AccountIds", new List<int>());
Generic versions, to implement suggestion in comment from @user420667
public class MultiDimList<T>: List<List<T>> { }
and for the dictionary,
public class MultiDimDictList<K, T>: Dictionary<K, List<T>> { }
// to use it, in client code
var myDicList = new MultiDimDictList<string, int> ();
myDicList.Add("ages", new List<T>());
myDicList["ages"].Add(23);
myDicList["ages"].Add(32);
myDicList["ages"].Add(18);
myDicList.Add("salaries", new List<T>());
myDicList["salaries"].Add(80000);
myDicList["salaries"].Add(100000);
myDicList.Add("accountIds", new List<T>());
myDicList["accountIds"].Add(321123);
myDicList["accountIds"].Add(342653);
or, even better, ...
public class MultiDimDictList<K, T>: Dictionary<K, List<T>>
{
public void Add(K key, T addObject)
{
if(!ContainsKey(key)) Add(key, new List<T>());
if (!base[key].Contains(addObject)) base[key].Add(addObject);
}
}
// and to use it, in client code
var myDicList = new MultiDimDictList<string, int> ();
myDicList.Add("ages", 23);
myDicList.Add("ages", 32);
myDicList.Add("ages", 18);
myDicList.Add("salaries", 80000);
myDicList.Add("salaries", 110000);
myDicList.Add("accountIds", 321123);
myDicList.Add("accountIds", 342653);
EDIT: to include an Add() method for nested instance:
public class NestedMultiDimDictList<K, K2, T>:
MultiDimDictList<K, MultiDimDictList<K2, T>>:
{
public void Add(K key, K2 key2, T addObject)
{
if(!ContainsKey(key)) Add(key,
new MultiDimDictList<K2, T>());
if (!base[key].Contains(key2))
base[key].Add(key2, addObject);
}
}
Login to virtual machine use below command to check ip address. (anyone will work)
If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1
If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine
Reference article: Show red color border for invalid input fields angualrjs
I used ng-class on all input fields.like below
<input type="text" ng-class="{submitted:newEmployee.submitted}" placeholder="First Name" data-ng-model="model.firstName" id="FirstName" name="FirstName" required/>
when I click on save button I am changing newEmployee.submitted value to true(you can check it in my question). So when I click on save, a class named submitted gets added to all input fields(there are some other classes initially added by angularjs).
So now my input field contains classes like this
class="ng-pristine ng-invalid submitted"
now I am using below css code to show red border on all invalid input fields(after submitting the form)
input.submitted.ng-invalid
{
border:1px solid #f00;
}
Thank you !!
Update:
We can add the ng-class at the form element instead of applying it to all input elements. So if the form is submitted, a new class(submitted) gets added to the form element. Then we can select all the invalid input fields using the below selector
form.submitted .ng-invalid
{
border:1px solid #f00;
}
Using LINQ is relatively much slower than using a predicate supplied to the Lists FindAll
method. Also be careful with LINQ as the enumeration of the list
is not actually executed until you access the result. This can mean that, when you think you have created a filtered list, the content may differ to what you expected when you actually read it.
Ambers's solution also works well for numpy arrays:
from pylab import *
import csv
array_=arange(0,10,1)
list_=[array_,array_*2,array_*3]
with open("output.csv", "wb") as f:
writer = csv.writer(f)
writer.writerows(list_)
Dennis answer is correct. However I would like to explain the solution in a bit more detailed way (for Windows User):
regedit
into the search field.HKEY_LOCAL_MACHINE\Software\JavaSoft
(Windows 10 seems to now have this here: HKEY_LOCAL_MACHINE\Software\WOW6432Node\JavaSoft
)New
-> Key
Prefs
and everything should work.Alternatively, save and execute a *.reg
file with the following content:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs]
A process normally has two outputs to screen: stdout (standard out), and stderr (standard error).
Normally informational messages go to sdout
, and errors and alerts go to stderr
.
You can turn off stdout
for a command by doing
MyCommand >/dev/null
and turn off stderr
by doing:
MyCommand 2>/dev/null
If you want both off, you can do:
MyCommand 2>&1 >/dev/null
The 2>&1
says send stderr to the same place as stdout.
What about using a HashMap
? Insertion, deletion, and retrieval are all O(1) operations. If you wanted to sort everything, you could grab a List of the values in the Map and run them through an O(n log n) sorting algorithm.
edit
A quick search has found LinkedHashMap, which maintains insertion order of your keys. It's not an exact solution, but it's pretty close.
The <b> tag is alive and well. <b> is not deprecated, but its use has been clarified and limited. <b> has no semantic meaning, nor does it convey vocal emphasis such as might be spoken by a screen reader. <b> does, however, convey printed empasis, as does the <i> tag. Both have a specific place in typograpghy, but not in spoken communication, mes frères.
To quote from http://www.whatwg.org/
The b element represents a span of text to be stylistically offset from the normal prose without conveying any extra importance, such as key words in a document abstract, product names in a review, or other spans of text whose typical typographic presentation is boldened.
Because it's the size of an instance of the type - presumably enum values are stored as (32-bit / 4-byte) ints here.
It depends on how and where you declared your array list. If it is an instance variable in the same class like your AnalyseArray() method you don't have to pass it along. The method will know the list and you can simply use the A in whatever purpose you need.
If they don't know each other, e.g. beeing a local variable or declared in a different class, define that your AnalyseArray() method needs an ArrayList parameter
public void AnalyseArray(ArrayList<Integer> theList){}
and then work with theList inside that method. But don't forget to actually pass it on when calling the method.AnalyseArray(A);
PS: Some maybe helpful Information to Variables and parameters.

regarding the recommended answer's code,
For my bot the recommended answer did not work. This is because I'm using Chrome which is requiring me to use KEYEVENTF_SCANCODE in my dwFlags.
To get his code to work I had to modify these code blocks:
class KEYBDINPUT(ctypes.Structure):
_fields_ = (("wVk", wintypes.WORD),
("wScan", wintypes.WORD),
("dwFlags", wintypes.DWORD),
("time", wintypes.DWORD),
("dwExtraInfo", wintypes.ULONG_PTR))
def __init__(self, *args, **kwds):
super(KEYBDINPUT, self).__init__(*args, **kwds)
# some programs use the scan code even if KEYEVENTF_SCANCODE

Just declare the list and append each element. For ex:
a = []
a.append('first item')
a.append('second item')
What about using UIPageViewController
with an array of UICollectionViewControllers
? You'd have to fetch proper number of items in each UICollectionViewController
, but it shouldn't be hard. You'd get exactly the same look as the Springboard has.
I've thought about this and in my opinion you have to set:
self.collectionView.pagingEnabled = YES;
and create your own collection view layout by subclassing UICollectionViewLayout
. From the custom layout object you can access self.collectionView
, so you'll know what is the size of the collection view's frame
, numberOfSections
and numberOfItemsInSection:
. With that information you can calculate cells' frames
(in prepareLayout
) and collectionViewContentSize
. Here're some articles about creating custom layouts:
You can do this (or an approximation of it) without creating the custom layout. Add UIScrollView
in the blank view, set paging enabled in it. In the scroll view add the a collection view. Then add to it a width constraint, check in code how many items you have and set its constant
to the correct value, e.g. (self.view.frame.size.width * numOfScreens)
. Here's how it looks (numbers on cells show the indexPath.row
): https://www.dropbox.com/s/ss4jdbvr511azxz/collection_view.mov If you're not satisfied with the way cells are ordered, then I'm afraid you'd have to go with 1. or 2.
Linux (and indeed Unix) gives you a third option.
Create a standalone executable which handles some part (or all parts) of your application, and invoke it separately for each process, e.g. the program runs copies of itself to delegate tasks to.
Create a standalone executable which starts up with a single thread and create additional threads to do some tasks
Only available under Linux/Unix, this is a bit different. A forked process really is its own process with its own address space - there is nothing that the child can do (normally) to affect its parent's or siblings address space (unlike a thread) - so you get added robustness.
However, the memory pages are not copied, they are copy-on-write, so less memory is usually used than you might imagine.
Consider a web server program which consists of two steps:
If you used threads, step 1 would be done once, and step 2 done in multiple threads. If you used "traditional" processes, steps 1 and 2 would need to be repeated for each process, and the memory to store the configuration and runtime data duplicated. If you used fork(), then you can do step 1 once, and then fork(), leaving the runtime data and configuration in memory, untouched, not copied.
So there are really three choices.
The problem with all of the answers given so far is that on the something borrowed site, the Mac bar remains totally hidden when scrolling up, and the provided answers don't accomplish that.
If you just use scrollTo
and then the user later scrolls up, the nav bar is revealed again, so it seems you have to put the whole site inside of a div and force scrolling to happen inside of that div rather than on the body which keeps the nav bar hidden during scrolling in any direction.
You can, however, still reveal the nav bar by touching near the top of the screen on apple devices.
Create a UNIQUE
constraint on your subs_email
column, if one does not already exist:
ALTER TABLE subs ADD UNIQUE (subs_email)
Use INSERT ... ON DUPLICATE KEY UPDATE
:
INSERT INTO subs
(subs_name, subs_email, subs_birthday)
VALUES
(?, ?, ?)
ON DUPLICATE KEY UPDATE
subs_name = VALUES(subs_name),
subs_birthday = VALUES(subs_birthday)
You can use the VALUES(col_name) function in the UPDATE clause to refer to column values from the INSERT portion of the INSERT ... ON DUPLICATE KEY UPDATE - dev.mysql.com
To keep the color and prevent an underline on the link:
legend.green-color a{
color:green;
text-decoration: none;
}
Adding a quick snippet to have it ready to execute:
Source: myparser.py
import argparse
parser = argparse.ArgumentParser(description="Flip a switch by setting a flag")
parser.add_argument('-w', action='store_true')
args = parser.parse_args()
print args.w
Usage:
python myparser.py -w
>> True
$suborder['payment_date'] = Carbon::parse($item['created_at'])->format('M d Y');
You can add it:
var meta = document.createElement('meta');
meta.httpEquiv = "X-UA-Compatible";
meta.content = "IE=edge";
document.getElementsByTagName('head')[0].appendChild(meta);
...but I wouldn't be surprised if by the time that ran, the browser had already made its decisions about how to render the page.
The real answer here has to be to output the correct tag from the server in the first place. (Sadly, you can't just not have the tag if you need to support IE. :-| )
Here's my overview about built-in zi/unzip (compress/decompress) capabilities in windows - How can I compress (/ zip ) and uncompress (/ unzip ) files and folders with batch file without using any external tools?
To unzip file you can use this script :
zipjs.bat unzip -source C:\myDir\myZip.zip -destination C:\MyDir -keep yes -force no
I solved my problem simply using ng-init
for default selection instead of ng-checked
<div ng-init="person.billing=FALSE"></div>
<input id="billing-no" type="radio" name="billing" ng-model="person.billing" ng-value="FALSE" />
<input id="billing-yes" type="radio" name="billing" ng-model="person.billing" ng-value="TRUE" />
You can use DataColumn.Ordinal
to get the index of the column in the DataTable
. So if you need the next column as mentioned use Column.Ordinal + 1
:
row[row.Table.Columns["ColumnName"].Ordinal + 1] = someOtherValue;
Aside from the excellent list by madgnome, I would add a duplicate code detector that is based off the command line (but is free):
With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.
Try with Kivy! kivy.org It's quite easy, multi platform and a really good documentation
The two answers are good. And I also suggest you a similar method:
<% @images.each.with_index do |page, index| %>
<% end %>
You might not see the difference between this and the accepted answer. Let me direct your eyes to these method calls: .each.with_index
see how it's .each
and then .with_index
.
To include png and jpg, you need to specify the Bounding Box explicitly.
\includegraphics[bb=0 0 1280 960]{images/some_image.png}
Where 1280 and 960 are respectively width and height.
In the past, I've solved this kind of problem with StringTemplate and Groovy Templates.
Ultimately, the decision of using a templating engine or not should be based on the following factors:
If any of the above applies to your project, I would consider using a templating engine, most of which provide this functionality, and more.
iframe have "sandbox" attribute that may block pop up etc
As someone said previously, the key here is for what reason you want to store user's ips.
I'll give an example from a registration system I work on and of course the solution just to contribute sth in this old discussion that comes frequently in my searches.
Many php registration libraries use ip to throttle/lock out failed attempts based on user's ip. Consider this table:
-- mysql
DROP TABLE IF EXISTS `attempts`;
CREATE TABLE `attempts` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`ip` varchar(39) NOT NULL, /*<<=====*/
`expiredate` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-- sqlite
...
Then, when a user tries to do a login or anything related with servicing like a password reset, a function is called at the start:
public function isBlocked() {
/*
* used one of the above methods to capture user's ip!!!
*/
$ip = $this->ip;
// delete attempts from this ip with 'expiredate' in the past
$this->deleteAttempts($ip, false);
$query = $this->dbh->prepare("SELECT count(*) FROM {$this->token->get('table_attempts')} WHERE ip = ?");
$query->execute(array($ip));
$attempts = $query->fetchColumn();
if ($attempts < intval($this->token->get('attempts_before_verify'))) {
return "allow";
}
if ($attempts < intval($this->token->get('attempts_before_ban'))) {
return "captcha";
}
return "block";
}
Say, for example, $this->token->get('attempts_before_ban') === 10
and 2 users come for the same ips as is the case in the previous codes where headers can be spoofed, then after 5 attempts each both are banned!
Even worst, if all come from the same proxy then only the first 10 users will be logged and all the rest will be banned!
The critical here is that we need a unique index on table attempts
and we can get it from a combination like:
`ip` varchar(39) NOT NULL,
`jwt_load varchar(100) NOT NULL
where jwt_load
comes from a http cookie that follows the json web token technology where we store only the encrypted payload that should contain an arbitrary/unique value for every user.
Of course the request should be modified to: "SELECT count(*) FROM {$this->token->get('table_attempts')} WHERE ip = ? AND jwt_load = ?"
and the class should also initiate a private $jwt
.
Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:
240p 360p 480p 720p 1080p
Resolution 426 x 240 640 x 360 854x480 1280x720 1920x1080
Video Bitrates
Maximum 700 Kbps 1000 Kbps 2000 Kbps 4000 Kbps 6000 Kbps
Recommended 400 Kbps 750 Kbps 1000 Kbps 2500 Kbps 4500 Kbps
Minimum 300 Kbps 400 Kbps 500 Kbps 1500 Kbps 3000 Kbps
It would appear as though this is the case, although the numbers dont sync up to the google table above:
// the bitrates, video width and file names for this clip
bitrates: [
{ url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
{ url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
{ url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
],
In handlebar version 3.0 onwards,
{{#each users as |user userId|}}
Id: {{userId}} Name: {{user.name}}
{{/each}}
In this particular example, user will have the same value as the current context and userId will have the index value for the iteration. Refer - http://handlebarsjs.com/block_helpers.html in block helpers section
I was using github earlier for one of my php project. While using github, I was using ssh instead of https. I had my machine set up like that and every time I used to commit and push the code, it would ask me my rsa key password.
After some days, I stopped working on the php project and forgot my rsa password. Recently, I started working on a java project and moved to bitbucket. Since, I had forgotten the password and there is no way to recover it I guess, I decided to use the https(recommended) protocol for the new project and got the same error asked in the question.
How I solved it?
Ran this command to tell my git to use https instead of ssh:
git config --global url."https://".insteadOf git://
Remove any remote if any
git remote rm origin
Redo everything from git init to git push and it works!
PS: I also un-installed ssh from my machine during the debug process thinking that, removing it will fix the problem. Yes I know!! :)
I experienced this exact same issue. For me, the OPTIONS request would go through, but the POST request would say "aborted." This led me to believe that the browser was never making the POST request at all. Chrome said something like "Caution provisional headers are shown" in the request headers but no response headers were shown. In the end I turned to debugging on Firefox which led me to find out my server was responding with an error and no CORS headers were present on the response. Chrome was actually receiving the response, but not allowing the response to be shown in the network view.
I assume you want lowercase the text. Solution is pretty simple:

Based on Kapitán Mlíko's answer with source above, I would change it to use the following:

You can use
String hex = String.format("#%02x%02x%02x", r, g, b);
Use capital X's if you want your resulting hex-digits to be capitalized (#FFFFFF
vs. #ffffff
).
You should put the include angular line first, before including any other js file
Use profiler module. It gives a very detailed profile.
import profile
profile.run('main()')
it outputs something like:

I've found it very informative.
GetThreadId
returns the ID of a given native thread. There are ways to make it work with managed threads, I'm sure, all you need to find is the thread handle and pass it to that function.
GetCurrentThreadId
returns the ID of the current thread.
GetCurrentThreadId
has been deprecated as of .NET 2.0: the recommended way is the Thread.CurrentThread.ManagedThreadId
property.
This is the fastest way:
if ($coll->isEmpty()) {...}
Other solutions like count
do a bit more than you need which costs slightly more time.
Plus, the isEmpty()
name quite precisely describes what you want to check there so your code will be more readable.
apply
and transform
There are two major differences between the transform
and apply
groupby methods.
apply
implicitly passes all the columns for each group as a DataFrame to the custom function.transform
passes each column for each group individually as a Series to the custom function.apply
can return a scalar, or a Series or DataFrame (or numpy array or even list).transform
must return a sequence (a one dimensional Series, array or list) the same length as the group.So, transform
works on just one Series at a time and apply
works on the entire DataFrame at once.
It can help quite a bit to inspect the input to your custom function passed to apply
or transform
.
Let's create some sample data and inspect the groups so that you can see what I am talking about:
import pandas as pd
import numpy as np
df = pd.DataFrame({'State':['Texas', 'Texas', 'Florida', 'Florida'],
'a':[4,5,1,3], 'b':[6,10,3,11]})
State a b
0 Texas 4 6
1 Texas 5 10
2 Florida 1 3
3 Florida 3 11
Let's create a simple custom function that prints out the type of the implicitly passed object and then raised an error so that execution can be stopped.
def inspect(x):
print(type(x))
raise
Now let's pass this function to both the groupby apply
and transform
methods to see what object is passed to it:
df.groupby('State').apply(inspect)
<class 'pandas.core.frame.DataFrame'>
<class 'pandas.core.frame.DataFrame'>
RuntimeError
As you can see, a DataFrame is passed into the inspect
function. You might be wondering why the type, DataFrame, got printed out twice. Pandas runs the first group twice. It does this to determine if there is a fast way to complete the computation or not. This is a minor detail that you shouldn't worry about.
Now, let's do the same thing with transform
df.groupby('State').transform(inspect)
<class 'pandas.core.series.Series'>
<class 'pandas.core.series.Series'>
RuntimeError
It is passed a Series - a totally different Pandas object.
So, transform
is only allowed to work with a single Series at a time. It is impossible for it to act on two columns at the same time. So, if we try and subtract column a
from b
inside of our custom function we would get an error with transform
. See below:
def subtract_two(x):
return x['a'] - x['b']
df.groupby('State').transform(subtract_two)
KeyError: ('a', 'occurred at index a')
We get a KeyError as pandas is attempting to find the Series index a
which does not exist. You can complete this operation with apply
as it has the entire DataFrame:
df.groupby('State').apply(subtract_two)
State
Florida 2 -2
3 -8
Texas 0 -2
1 -5
dtype: int64
The output is a Series and a little confusing as the original index is kept, but we have access to all columns.
It can help even more to display the entire pandas object within the custom function, so you can see exactly what you are operating with. You can use print
statements by I like to use the display
function from the IPython.display
module so that the DataFrames get nicely outputted in HTML in a jupyter notebook:
from IPython.display import display
def subtract_two(x):
display(x)
return x['a'] - x['b']
The other difference is that transform
must return a single dimensional sequence the same size as the group. In this particular instance, each group has two rows, so transform
must return a sequence of two rows. If it does not then an error is raised:
def return_three(x):
return np.array([1, 2, 3])
df.groupby('State').transform(return_three)
ValueError: transform must return a scalar value for each group
The error message is not really descriptive of the problem. You must return a sequence the same length as the group. So, a function like this would work:
def rand_group_len(x):
return np.random.rand(len(x))
df.groupby('State').transform(rand_group_len)
a b
0 0.962070 0.151440
1 0.440956 0.782176
2 0.642218 0.483257
3 0.056047 0.238208
transform
If you return just a single scalar from your custom function, then transform
will use it for each of the rows in the group:
def group_sum(x):
return x.sum()
df.groupby('State').transform(group_sum)
a b
0 9 16
1 9 16
2 4 14
3 4 14
That's an old thread, but in case you want to upload the image having same extension-
$image = $request->image;
$imageInfo = explode(";base64,", $image);
$imgExt = str_replace('data:image/', '', $imageInfo[0]);
$image = str_replace(' ', '+', $imageInfo[1]);
$imageName = "post-".time().".".$imgExt;
Storage::disk('public_feeds')->put($imageName, base64_decode($image));
You can create 'public_feeds' in laravel's filesystem.php-
'public_feeds' => [
'driver' => 'local',
'root' => public_path() . '/uploads/feeds',
],
Just use the __block
prefix to declare and assign any type of variable inside a block.
For example:
__block Person *aPerson = nil;
__block NSString *name = nil;
Don't use with Router.
handleSubmit(e){
e.preventDefault();
this.props.form.validateFieldsAndScroll((err,values)=>{
if(!err){
this.setState({
visible:false
});
this.props.form.resetFields();
console.log(values.username);
const path = '/list/';
this.props.history.push(path);
}
})
}
It works well.
Ruby provides a built-in function for checking the length of a string. Say it's called s
:
if s.length <= 25
# We're OK
else
# Too long
end
I wrote a general method that will add a border on whichever sides you wish in any UIView
. You can define thickness, color, margins and zOrder
for each side.
/*
view: the view to draw border around
thickness: thickness of the border on the given side
color: color of the border on the given side
margin: space between the border's outer edge and the view's frame edge on the given side.
zOrder: defines the order to add the borders to the view. The borders will be added by zOrder from lowest to highest, thus making the highest priority border visible when two borders overlap at the corners.

I just ran into the same problem (lack of hashchange event in IE7). A workaround that suited for my purposes was to bind the click event of the hash-changing links.
<a class='hash-changer' href='#foo'>Foo</a>
<script type='text/javascript'>
if (("onhashchange" in window) && !($.browser.msie)) {
//modern browsers
$(window).bind('hashchange', function() {
var hash = window.location.hash.replace(/^#/,'');
//do whatever you need with the hash
});
} else {
//IE and browsers that don't support hashchange
$('a.hash-changer').bind('click', function() {
var hash = $(this).attr('href').replace(/^#/,'');
//do whatever you need with the hash
});
}
</script>
I've run into this a few times and it was due to a certificate chain being incomplete. If you are using the standard java trust store, it may not have a certificate that is needed to complete the certificate chain which is required to validate the certificate of the SSL site you are connecting to.
I ran into this problem with some DigiCert certificates and had to manually add the intermediary cert myself.
One thing to note is that not all libraries will use the same meaning for pi, of course, so it never hurts to know what you're using. For example, the symbolic math library Sympy's representation of pi is not the same as math and numpy:
import math
import numpy
import scipy
import sympy
print(math.pi == numpy.pi)
> True
print(math.pi == scipy.pi)
> True
print(math.pi == sympy.pi)
> False
I've had a similar issue, and I've resolved it by statically linking libstdc++
into the program I was compiling, like so:
$ LIBS=-lstdc++ ./configure ... etc.
instead of the usual
$ ./configure ... etc.
There might be problems with this solution to do with loading shared libraries at runtime, but I haven't looked into the issue deeply enough to comment.
If your computation involves various steps, arbitrary precision arithmetic won't cover you 100%.
The only reliable way to use a perfect representation of results(Use a custom Fraction data type that will batch division operations to the last step) and only convert to decimal notation in the last step.
Arbitrary precision won't help because there always can be numbers that has so many decimal places, or some results such as 0.6666666
... No arbitrary representation will cover the last example. So you will have small errors in each step.
These errors will add-up, may eventually become not easy to ignore anymore. This is called Error Propagation.
If you want to use the cd or ls functions , you need proper identifiers before the function names ( % and ! respectively) use %cd and !ls to navigate
.
!ls # to find the directory you're in ,
%cd ./samplefolder #if you wanna go into a folder (say samplefolder)
or if you wanna go out of the current folder
%cd ../
and then navigate to the required folder/file accordingly
this error usually shows if the name of your struct is different from the initialization of your struct in the code, so normally, c will find the name of the struct you put and if the original struct is not found, this would usually appear, or if you point a pointer pointed into that pointer, the error will show up.
There is a fairly well maintained repo on github that has a CSV (with semicolon delimiters), XML, and JSON source of countries, country codes, and other information.
Full answer to the original question that was talking about a possible different path on local and remote is below
git fetch origin
git diff master -- [local-path] origin/master -- [remote-path]
Assuming the local path is docs/file1.txt and remote path is docs2/file1.txt, use git diff master -- docs/file1.txt origin/master -- docs2/file1.txt
