Quite a few applications seem to implement Steganography on JPEG, so it's feasible:
http://www.jjtc.com/Steganography/toolmatrix.htm
Here's an article regarding a relevant algorithm (PM1) to get you started:

A bit late in the game but just in case it helps anyone.
If you are testing using the Sandbox and on the payment page you want to test payments NOT using a PayPal account but using the "Pay with Debit or Credit Card option" (i.e. when a regular Joe/Jane, NOT PayPal users, want to buy your stuff) and want to save yourself some time: just go to a site like http://www.getcreditcardnumbers.com/ and get numbers from there. You can use any Expiry date (in the future) and any numeric CCV (123 works).
The "test credit card numbers" in the PayPal documentation are just another brick in their infuriating wall of convoluted stuff.
I got the url above from PayPal's tech support.
Tested using a simple Hosted button and IPN. Good luck.
We can also use this with the $_GET
method
$employee_id = 'EMP-1234';
header('Location: employee.php?id='.$employee_id);
Add below code in your client code :
static {
Security.insertProviderAt(new BouncyCastleProvider(),1);
}
with this there is no need to add any entry in java.security file.
Thanks Tim Stone, naunu, and Kevin Bond, those answers really helped me. Here is my adaption of your code. I added the functionality to be redirected back to the desktop site from m.example.com in case the user does not visit the site with a mobile device. Additionally I added an environment variable to preserve http/https requests:
# Set an environment variable for http/https.
RewriteCond %{HTTPS} =on
RewriteRule ^(.*)$ - [env=ps:https]
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ - [env=ps:http]
# Check if m=1 is set and set cookie 'm' equal to 1.
RewriteCond %{QUERY_STRING} (^|&)m=1(&|$)
RewriteRule ^ - [CO=m:1:example.com]
# Check if m=0 is set and set cookie 'm' equal to 0.
RewriteCond %{QUERY_STRING} (^|&)m=0(&|$)
RewriteRule ^ - [CO=m:0:example.com]
# Cookie can't be set and read in the same request so check.
RewriteCond %{QUERY_STRING} (^|&)m=0(&|$)
RewriteRule ^ - [S=1]
# Check if this looks like a mobile device.
RewriteCond %{HTTP:x-wap-profile} !^$ [OR]
RewriteCond %{HTTP_USER_AGENT} "android|blackberry|ipad|iphone|ipod|iemobile|opera mobile|palmos|webos|googlebot-mobile" [NC,OR]
RewriteCond %{HTTP:Profile} !^$
# Check if we're not already on the mobile site.
RewriteCond %{HTTP_HOST} !^m\.
# Check if cookie is not set to force desktop site.
RewriteCond %{HTTP_COOKIE} !^.*m=0.*$ [NC]
# Now redirect to the mobile site preserving http or https.
RewriteRule ^ %{ENV:ps}://m.example.com%{REQUEST_URI} [R,L]
# Check if this looks like a desktop device.
RewriteCond %{HTTP_USER_AGENT} "!(android|blackberry|ipad|iphone|ipod|iemobile|opera mobile|palmos|webos|googlebot-mobile)" [NC]
# Check if we're on the mobile site.
RewriteCond %{HTTP_HOST} ^m\.
# Check if cookie is not set to force mobile site.
RewriteCond %{HTTP_COOKIE} !^.*m=1.*$ [NC]
# Now redirect to the mobile site preserving http or https.
RewriteRule ^ %{ENV:ps}://example.com%{REQUEST_URI} [R,L]
This seems to work fine except one thing: When I'm on the desktop site with a desktop device and I visit m.example.com/?m=1, I'm redirected to example.com. When I try again, I "stay" at m.example.com. It seems as if the cookie isn't set and/or read correctly the first time.
Maybe there is a better way to determine if the device is a desktop device, I just negated the device detection from above.
And I'm wondering if this way all mobile devices are detected. In Tim Stone's and naunu's code that part is much larger.
Chris Dents' answer has already covered the OPs' question but seeing as this was the top search on google for PowerShell format string as date
I thought I'd give a different string example.
If like me, you get the time string like this 20190720170000.000000+000
An important thing to note is you need to use ToUniversalTime()
when using [System.Management.ManagementDateTimeConverter]
otherwise you get offset times against your input.

When you have a conflict during rebase you have three options:
You can run git rebase --abort
to completely undo the rebase. Git will return you to your branch's state as it was before git rebase was called.
You can run git rebase --skip
to completely skip the commit. That means
that none of the changes introduced by the problematic commit will be included. It is very rare that you would choose this option.
You can fix the conflict as iltempo said. When you're finished, you'll need to call git rebase --continue
. My mergetool is kdiff3 but there are many more which you can use to solve conflicts. You only need to set your merge tool in git's settings so it can be invoked when you call git mergetool

If none of the above works for you, then go for a walk and try again :)

pandas provides high level data manipulation tools built on top of NumPy. NumPy by itself is a fairly low-level tool, similar to MATLAB. pandas on the other hand provides rich time series functionality, data alignment, NA-friendly statistics, groupby, merge and join methods, and lots of other conveniences. It has become very popular in recent years in financial applications. I will have a chapter dedicated to financial data analysis using pandas in my upcoming book.
As additional information, to accomplish same thing in SQL Server, you just need to remove the "FROM dual" part of the query.
Restartable mode (/Z) has to do with a partially-copied file. With this option, should the copy be interrupted while any particular file is partially copied, the next execution of robocopy can pick up where it left off rather than re-copying the entire file.
That option could be useful when copying very large files over a potentially unstable connection.
Backup mode (/B) has to do with how robocopy reads files from the source system. It allows the copying of files on which you might otherwise get an access denied error on either the file itself or while trying to copy the file's attributes/permissions. You do need to be running in an Administrator context or otherwise have backup rights to use this flag.
Adding to @HYRY's answer in1d seems to be fastest for numpy. This is using numpy 1.8 and python 2.7.6.
In this test in1d was fastest, however 10 in a
look cleaner:
a = arange(0,99999,3)
%timeit 10 in a
%timeit in1d(a, 10)
10000 loops, best of 3: 150 µs per loop
10000 loops, best of 3: 61.9 µs per loop
Constructing a set is slower than calling in1d, but checking if the value exists is a bit faster:
s = set(range(0, 99999, 3))
%timeit 10 in s
10000000 loops, best of 3: 47 ns per loop

Welcome to the world of Data Oriented Design. The basic mantra is to Sort, Eliminate Branches, Batch, Eliminate virtual
calls - all steps towards better locality.
Since you tagged the question with C++, here's the obligatory typical C++ Bullshit. Tony Albrecht's Pitfalls of Object Oriented Programming is also a great introduction into the subject.
This gives you the needed results:
string time = "16:23:01";
var result = Convert.ToDateTime(time);
string test = result.ToString("hh:mm:ss tt", CultureInfo.CurrentCulture);
//This gives you "04:23:01 PM" string
You could also use CultureInfo.CreateSpecificCulture("en-US")
as not all cultures will display AM/PM.

A bit manual searching but its an alternative way...
Find the Oracle home or where the installation files for Oracle is installed on your linux server.
cd / <-- Goto root directory
find . -print| grep -i dbm*.sql
Result varies on how you installed Oracle but mine displays this
/db/oracle
Goto the folder
less /db/oracle/db1/sqlplus/doc/README.htm
scroll down and you should see something like this
SQL*Plus Release Notes - Release 11.2.0.2
var inputs = $('#foo');
inputs.each(function(){
this.style.textTransform = 'uppercase';
})
.keyup(function(){
this.value = this.value.toUpperCase();
});
In addition, use collections.Counter to refactor your code:
from collections import Counter
words = ['a', 'b', 'c', 'a']
Counter(words).keys() # equals to list(set(words))
Counter(words).values() # counts the elements' frequency
Output:
['a', 'c', 'b']
[2, 1, 1]
Parenthesis is not required to instantiate a class object when you don't intend to use a parameterised constructor.
Just use Foo foo2;
It will work.
add a clear:both
. assuming that your columns are floating. Depending on how your height is specified parent you may need an overflow:auto;
<body>
<div id="parent">
<div id="childRightCol">
<div>
<div id="childLeftCol">
<div>
<div id="clear" style="clear:both;"></div>
</div>
</body>
I'm afraid there's not enough information in your question to be certain about what's going on, since you haven't replied to my follow-up question, but this may be of help in any case.
That error means that projectfolder
is already staged ("already exists in the index"). To find out what's going on here, try to list everything in the index under that folder with:
git ls-files --stage projectfolder
The first column of that output will tell you what type of object is in the index at projectfolder
. (These look like Unix filemodes, but have special meanings in git.)
I suspect that you will see something like:
160000 d00cf29f23627fc54eb992dde6a79112677cd86c 0 projectfolder
(i.e. a line beginning with 160000
), in which case the repository in projectfolder
has already been added as a "gitlink". If it doesn't appear in the output of git submodule
, and you want to re-add it as a submodule, you can do:
git rm --cached projectfolder
... to unstage it, and then:
git submodule add url_to_repo projectfolder
... to add the repository as a submodule.
However, it's also possible that you will see many blobs listed (with file modes 100644
and 100755
), which would suggest to me that you didn't properly unstage the files in projectfolder
before copying the new repository into place. If that's the case, you can do the following to unstage all of those files:
git rm -r --cached projectfolder
... and then add the submodule with:
git submodule add url_to_repo projectfolder
.... char ch; ... ch=scan.next().charAt(0); . . It's the easy way to get character.
You can use MessageDigest in the following way:
public static String getSHA256(String data){
StringBuffer sb = new StringBuffer();
try{
MessageDigest md = MessageDigest.getInstance("SHA-256");
md.update(data.getBytes());
byte byteData[] = md.digest();
for (int i = 0; i < byteData.length; i++) {
sb.append(Integer.toString((byteData[i] & 0xff) + 0x100, 16).substring(1));
}
} catch(Exception e){
e.printStackTrace();
}
return sb.toString();
}
You could try returning a VBA Collection.
As long as you dealing with pair values, like "Version=1.31", you could store the identifier as a key ("Version") and the actual value (1.31) as the item itself.
Dim c As New Collection
Dim item as Variant
Dim key as String
key = "Version"
item = 1.31
c.Add item, key
'Then return c
Accessing the values after that it's a breeze:
c.Item("Version") 'Returns 1.31
or
c("Version") '.Item is the default member
Does it make sense?
Numbers inherit from the Number
constructor which doesn't have the .toLowerCase
method. You can look it up as a matter of fact:
"toLowerCase" in Number.prototype; // false
Try this one in your css document,
-fx-background-color : #ffaadd;
or
-fx-base : #ffaadd;
Also, you can set background color on your object with this code directly.
yourPane.setBackground(new Background(new BackgroundFill(Color.DARKGREEN, CornerRadii.EMPTY, Insets.EMPTY)));
Use sysdate-1 to subtract one day from system date.
select sysdate, sysdate -1 from dual;

PythonQL offers an embedded syntax that IMHO is an improvement on SQL, principally because group
, window
, where
, let
, etc. can be freely intermixed.
$ cat x.py
#coding: pythonql
data = [{"x": 2, "y": 0}, {"x": 3, "y": 1}, {"x": 4, "y": 1}]
q = [x match {'x': as x, 'y': as y} in data where y > 0]
print(sum(q))
print(list(q))
q = [x match {'x': as x, 'y': as y} as d in data where d['y'] > 0]
print(sum(q))
This code shows two different answers to your question, depending on your need to handle the entire structure or just the value. Execution gives you the expected result.
$ python x.py

WOFF 2.0, based on the Brotli compression algorithm and other improvements over WOFF 1.0 giving more than 30 % reduction in file size, is supported in Chrome, Opera, and Firefox.
http://en.wikipedia.org/wiki/Web_Open_Font_Format http://en.wikipedia.org/wiki/Brotli
http://sth.name/2014/09/03/Speed-up-webfonts/ has an example on how to use it.
Basically you add a src url to the woff2 file and specify the woff2 format. It is important to have this before the woff-format: the browser will use the first format that it supports.
Node.js is a runtime that compiles and executes javaScript. It can be used to develop application that runs end-to-end in JavaScript i..e both client side and server side uses javascript code unlike most of todays' application with rich client framework (angularJs, extJs) and RESTful server side APIs
After lot of struggle finally got it working. ( Perfectly tested)
The below example will also support the fact that color of already clicked button should not be changes
JQuery Code
var flag = 0; // Flag is to check if you are hovering on already clicked item
$("a").click(function() {

$(this).addClass("YourColorClass");
flag=1;
});
$("a").mouseover(function() {
if ($(this).hasClass("YourColorClass")) {
flag=1;
}
else{
$(this).addClass("YourColorClass");
};
});
$("a").mouseout(function() {
if (flag == 0) {
$(this).removeClass("YourColorClass");
}
else{
flag = 0;
}
});
Simple way of creating newtonsoft JObject from Properties.
This is a Sample User Properties
public class User
{
public string Name;
public string MobileNo;
public string Address;
}
and i want this property in newtonsoft JObject is:
JObject obj = JObject.FromObject(new User()
{
Name = "Manjunath",
MobileNo = "9876543210",
Address = "Mumbai, Maharashtra, India",
});
Output will be like this:
{"Name":"Manjunath","MobileNo":"9876543210","Address":"Mumbai, Maharashtra, India"}
Another pitfall with this is that command substitution — $()
— strips trailing newlines. Probably not always important, but if you really want to preserve exactly what was output, you'll have to use another line and some quoting:
RESULTX="$(./myscript; echo x)"
RESULT="${RESULTX%x}"
This is especially important if you want to handle all possible filenames (to avoid undefined behavior like operating on the wrong file).
don't have to use grep either
an example:
sed -n '/searchwords/{s/^\(.\{12\}\).*/\1/g;p}' file
As all answers posted above are well explained, I want to add something which I faced today.
When you export something using exports then you have to use it with variable. Like,
File1.js
exports.a = 5;
In another file
File2.js
const A = require("./File1.js");
console.log(A.a);
and using module.exports
File1.js
module.exports.a = 5;
In File2.js
const A = require("./File1.js");
console.log(A.a);
and default module.exports
File1.js
module.exports = 5;
in File2.js
const A = require("./File2.js");
console.log(A);
OnFragmentInteractionListener
is the default implementation for handling fragment to activity communication. This can be implemented based on your needs. Suppose if you need a function in your activity to be executed during a particular action within your fragment, you may make use of this callback method. If you don't need to have this interaction between your hosting activity
and fragment
, you may remove this implementation.
In short you should implement
the listener in your fragment hosting activity if you need the fragment-activity interaction like this
public class MainActivity extends Activity implements
YourFragment.OnFragmentInteractionListener {..}
and your fragment should have it defined like this
public interface OnFragmentInteractionListener {
// TODO: Update argument type and name
void onFragmentInteraction(Uri uri);
}
also provide definition for void onFragmentInteraction(Uri uri);
in your activity
or else just remove the listener
initialisation from your fragment's onAttach
if you dont have any fragment-activity interaction
I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.
By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.
Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.
The correct way is to set the BindByName property of OracleCommand to true as below:
var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;
You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post
If you have query like:
SELECT * FROM user WHERE id IN (1, 2, 3, 4 -- and thousands of another keys)
you may increase performace if rewrite your query like:
SELECT * FROM user WHERE id = ANY(VALUES (1), (2), (3), (4) -- and thousands of another keys)
Not the most readable solution, but you can mix the result from a value-of with plain text:
<a>
<xsl:attribute name="href">
Text<xsl:value-of select="/*/properties/property[@name='report']/@value"/>Text
</xsl:attribute>
</a>
As defined by the SQL-92 Standard, when comparing two strings of differing widths, the narrower value is right-padded with spaces to make it is same width as the wider value. Therefore, all string values that consist entirely of spaces (including zero spaces) will be deemed to be equal e.g.
'' = ' ' IS TRUE
'' = ' ' IS TRUE
' ' = ' ' IS TRUE
' ' = ' ' IS TRUE
etc
Therefore, this should work regardless of how many spaces make up the some_col
value:
SELECT *
FROM T
WHERE some_col IS NULL
OR some_col = ' ';
or more succinctly:
SELECT *
FROM T
WHERE NULLIF(some_col, ' ') IS NULL;
After adding the icon to the toolbar and when modifying the selected icon, the ampersand in the name input is specifying that the next character is the character used along with Alt for the shortcut. Since you must select a display option from the Modify Selection drop down menu that includes displaying the text, you could also write &C in the name field and get the same result as &Comment Block (without the lengthy text).
One way to solve this problem i found is to seperate out the construction into a seperate factory. For example I have an abstract class called IQueueItem, and I need a way to translate that object to and from another object (CloudQueueMessage). So on the interface IQueueItem i have -
public interface IQueueItem
{
CloudQueueMessage ToMessage();
}
Now, I also need a way for my actual queue class to translate a CloudQueueMessage back to a IQueueItem - ie the need for a static construction like IQueueItem objMessage = ItemType.FromMessage. Instead I defined another interface IQueueFactory -
public interface IQueueItemFactory<T> where T : IQueueItem
{
T FromMessage(CloudQueueMessage objMessage);
}
Now I can finally write my generic queue class without the new() constraint which in my case was the main issue.
public class AzureQueue<T> where T : IQueueItem
{
private IQueueItemFactory<T> _objFactory;
public AzureQueue(IQueueItemFactory<T> objItemFactory)
{
_objFactory = objItemFactory;
}
public T GetNextItem(TimeSpan tsLease)
{
CloudQueueMessage objQueueMessage = _objQueue.GetMessage(tsLease);
T objItem = _objFactory.FromMessage(objQueueMessage);
return objItem;
}
}
now I can create an instance that satisfies the criteria for me
AzureQueue<Job> objJobQueue = new JobQueue(new JobItemFactory())
hopefully this helps someone else out someday, obviously a lot of internal code removed to try to show the problem and solution
The <pre>
-Element stands for "pre-formatted-text" and is intended to keep the formatting of the text (or whatever) between its tags. Therefore it is actually not inteded to have automatic word-wrapping or line-breaks within the <pre>
-Tag
Text in a element is displayed in a fixed-width font (usually Courier), and it preserves both spaces and line breaks.

You still need to worry about memory when you are writing managed code unless your application is trivial. I will suggest two things: first, read CLR via C# because it will help you understand memory management in .NET. Second, learn to use a tool like CLRProfiler (Microsoft). This can give you an idea of what is causing your memory leak (e.g. you can take a look at your large object heap fragmentation)
var http = require('http');
var url = process.argv[2];

});
response.on("end", function() {
console.log(finalData.length);
console.log(finalData.toString());
});
});

When compiling memcached under Centos 5.x i got the same problem.
The solution is to upgrade gcc and g++ to version 4.4 at least.
Make sure your CC/CXX is set (exported) to right binaries before compiling.

I have just made bypass this error by just changing the values of the "length" in the original database to the total of around "1000" by changing its structure, and then exporting the same, to the server. :)

Does this do what you want?
p <- ggplot(myData, aes(foo, bar)) + geom_whateverGeomYouWant(more = options) +
p + scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
opts(legend.position = "none")
The best solution that i found for myself
SimpleDateFormat("XXX", Locale.getDefault()).format(System.currentTimeMillis())
+03:00
You can try to change pattern (the "xxx" string) to get the result you want, for example:
SimpleDateFormat("XX", Locale.getDefault()).format(System.currentTimeMillis())
+0300
SimpleDateFormat("X", Locale.getDefault()).format(System.currentTimeMillis())
+03
Pattern can also apply another letters and the result will be different
SimpleDateFormat("Z", Locale.getDefault()).format(System.currentTimeMillis())
+0300
More about this you can find here: https://developer.android.com/reference/java/text/SimpleDateFormat.html

IISReset restarts the entire webserver (including all associated sites). If you're just looking to reset a single ASP.NET website, you should just recycle that Application Domain.
you can use LINQ
string abc = "abc";
char getresult = abc.Where((item, index) => index == 2).Single();
Setup:
My OS windows 8 64bit
Eclipse version Standard/SDK Kepler Service Release 2
My JDK is jdk-8u5-windows-i586
My JRE is jre-8u5-windows-i586
This how I overcome my error.
At the very first my Class.forName("sun.jdbc.odbc.JdbcOdbcDriver")
also didn't work.
Then I login to this website and downloaded the UCanAccess 2.0.8 zip (as Mr.Gord Thompson said) file and unzip it.
Then you will also able to find these *.jar files in that unzip folder:
ucanaccess-2.0.8.jar
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.0.4.jar
Then what I did was I copied all these 5 files and paste them in these 2 locations:
C:\Program Files (x86)\eclipse\lib
C:\Program Files (x86)\eclipse\lib\ext
(I did that funny thing becoz I was unable to import these libraries to my project)
Then I reopen the eclipse with my project.then I see all that *.jar files in my project's JRE System Library folder.
Finally my code works.
public static void main(String[] args)
{
try
{
Connection conn=DriverManager.getConnection("jdbc:ucanaccess://C:\\Users\\Hasith\\Documents\\JavaDatabase1.mdb");
Statement stment = conn.createStatement();
String qry = "SELECT * FROM Table1";
ResultSet rs = stment.executeQuery(qry);
while(rs.next())
{
String id = rs.getString("ID") ;
String fname = rs.getString("Nama");
System.out.println(id + fname);
}
}
catch(Exception err)
{
System.out.println(err);
}
//System.out.println("Hasith Sithila");
}
Actually, I think this is the best way.
from django.core.validators import URLValidator
from django.core.exceptions import ValidationError
val = URLValidator(verify_exists=False)
try:
val('http://www.google.com')
except ValidationError, e:
print e
If you set verify_exists
to True
, it will actually verify that the URL exists, otherwise it will just check if it's formed correctly.
edit: ah yeah, this question is a duplicate of this: How can I check if a URL exists with Django’s validators?
var = False

No, Integer
and String
are different types. To convert an integer to string use: String.valueOf(integer)
, or Integer.toString(integer)
for primitive, or Integer.toString()
for the object.

declare
v_result clob;
begin
---- some operation on v_result
dbms_lob.substr( v_result, 4000 ,length(v_result) - 3999 );
end;
/
In dbms_lob.substr
first parameter
is clob
which you want to extract .
Second parameter
is how much length of clob you want to extract.
Third parameter
is from which word you want to extract .
In above example i know my clob size is more than 50000 , so i want last 4000 character .
Oauth is definitely gaining momentum and becoming popular among enterprise APIs as well. In the app and data driven world, Enterprises are exposing APIs more and more to the outer world in line with Google, Facebook, twitter. With this development a 3 way triangle of authentication gets formed
1) API provider- Any enterprise which exposes their assets by API, say Amazon,Target etc 2) Developer - The one who build mobile/other apps over this APIs 3) The end user- The end user of the service provided by the - say registered/guest users of Amazon
Now this develops a situation related to security - (I am listing few of these complexities) 1) You as an end user wants to allow the developer to access APIs on behalf of you. 2) The API provider has to authenticate the developer and the end user 3) The end user should be able to grant and revoke the permissions for the consent they have given 4) The developer can have varying level of trust with the API provider, in which the level of permissions given to her is different
The Oauth is an authorization framework which tries to solve the above mentioned problem in a standard way. With the prominence of APIs and Apps this problem will become more and more relevant and any standard which tries to solve it - be it ouath or any other - will be something to care about as an API provider/developer and even end user!
Try using MAX
with a GROUP BY
.
SELECT u.userName, MAX(c.carPrice)
FROM users u
LEFT JOIN cars c ON u.id = c.belongsToUser
WHERE u.id = 4;
GROUP BY u.userName;
GROUP BY
The group by clause is used to split the selected records into groups based on unique combinations of the group by columns. This then allows us to use aggregate functions (eg. MAX, MIN, SUM, AVG, ...) that will be applied to each group of records in turn. The database will return a single result record for each grouping.
For example, if we have a set of records representing temperatures over time and location in a table like this:
Location Time Temperature
-------- ---- -----------
London 12:00 10.0
Bristol 12:00 12.0
Glasgow 12:00 5.0
London 13:00 14.0
Bristol 13:00 13.0
Glasgow 13:00 7.0
...
Then if we want to find the maximum temperature by location, then we need to split the temperature records into groupings, where each record in a particular group has the same location. We then want to find the maximum temperature of each group. The query to do this would be as follows:
SELECT Location, MAX(Temperature)
FROM Temperatures
GROUP BY Location;
The easiest way to achieve this is to create only 1 table with both Table A and B fields NOT NULL. This way it is impossible to have one without the other.
How about using the ExecutorService.shutDownNow()
method as described in http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ExecutorService.html? It seems to be the simplest solution.

I created a new project in XCode with the sources and changed the C++ Standard Library from the default libc++ to libstdc++ as in this and this.
First, launch your Safari browser from the Home screen and go to the webpage that you want to view full screen.
After locating the webpage, tap on the arrow icon at the top of your screen.
In the drop-down menu, tap on the Add to Home Screen option.
The Add to Home window should be displayed. You can customize the description that will appear as a title on the home screen of your iPad. When you are done, tap on the Add button.
A new icon should now appear on your home screen. Tapping on the icon will open the webpage in the fullscreen mode.
Note: The icon on your iPad home screen only opens the bookmarked page in the fullscreen mode. The next page you visit will be contain the Safari address and title bars. This way of playing your webpage or HTML5 presentation in the fullscreen mode works if the source code of the webpage contains the following tag:
<meta name="apple-mobile-web-app-capable" content="yes">
You can add this tag to your webpage using a third-party tool, for example iWeb SEO Tool or any other you like. Please note that you need to add the tag first, refresh the page and then add a bookmark to your home screen.
You can try the following tutorial, it may help you to move forward:
With pure html (no JS), you can't really substitute a radio-button for an image (at least, I don't think you can). You could, though use the following to make the same connection to the user:
<form action="" method="post">
<fieldset>
<input type="radio" name="feeling" id="feelingSad" value="sad" /><label for="feelingSad"><img src="path/to/sad.png" /></label>
<label for="feelingHappy"><input type="radio" name="feeling" id="feelingHappy" value="happy" /><img src="path/to/happy.png" /></label>
</fieldset>
</form>
public string HtmlAgi(string url, string key)
{
var Webget = new HtmlWeb();
var doc = Webget.Load(url);
HtmlNode ourNode = doc.DocumentNode.SelectSingleNode(string.Format("//meta[@name='{0}']", key));
if (ourNode != null)
{
return ourNode.GetAttributeValue("content", "");
}
else
{
return "not fount";
}
}
For ubuntu with Plesk installed run apt-get install plesk-php56-dev
, for other versions just change XX in phpXX (without the dot)
- (void)applicationDidEnterBackground:(UIApplication *)application
{
UILocalNotification *notification = [[UILocalNotification alloc]init];
notification.repeatInterval = NSDayCalendarUnit;
[notification setAlertBody:@"Hello world"];
[notification setFireDate:[NSDate dateWithTimeIntervalSinceNow:1]];
[notification setTimeZone:[NSTimeZone defaultTimeZone]];
[application setScheduledLocalNotifications:[NSArray arrayWithObject:notification]];
}
This is worked, but in iOS 8.0 and later, your application must register for user notifications using -[UIApplication registerUserNotificationSettings:]
before being able to schedule and present UILocalNotifications, do not forget this.
SELECT name, city, count(*) as qty
FROM stuff

I think it'd be okay if you commented it, e.g. // ^ == XOR
.
This is what I did on the controller
var collectionDate = '2002-04-26T09:00:00';
var date = new Date(collectionDate);
//then pushed all my data into an array $scope.rows which I then used in the directive
I ended up formatting the date to my desired pattern on the directive as follows.
var data = new google.visualization.DataTable();
data.addColumn('date', 'Dates');
data.addColumn('number', 'Upper Normal');
data.addColumn('number', 'Result');
data.addColumn('number', 'Lower Normal');
data.addRows(scope.rows);
var formatDate = new google.visualization.DateFormat({pattern: "dd/MM/yyyy"});
formatDate.format(data, 0);
//set options for the line chart
var options = {'hAxis': format: 'dd/MM/yyyy'}
//Instantiate and draw the chart passing in options
var chart = new google.visualization.LineChart($elm[0]);
chart.draw(data, options);
This gave me dates ain the format of dd/MM/yyyy (26/04/2002) on the x axis of the chart.
There is nothing built in afaik, but building it yourself should be easy. I would do as you suggest and use reflection to obtain the properties and use them to create the columns of the table. Then I would step through each item in the IEnumerable and create a row for each. The only caveat is if your collection contains items of several types (say Person and Animal) then they may not have the same properties. But if you need to check for it depends on your use.
I have come across this with the Hero, using what I thought was a published API. In the end, I used a test to see if the intent could be received:
private boolean isCallable(Intent intent) {
List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
return list.size() > 0;
}
In use when I would usually just start the activity:
final Intent intent = new Intent("com.android.camera.action.CROP");
intent.setClassName("com.android.camera", "com.android.camera.CropImage");
if (isCallable(intent)) {
// call the intent as you intended.
} else {
// make alternative arrangements.
}
obvious: If you go down this route - using non-public APIs - you must absolutely provide a fallback which you know definitely works. It doesn't have to be perfect, it can be a Toast saying that this is unsupported for this handset/device, but you should avoid an uncaught exception. end obvious.
I find the Open Intents Registry of Intents Protocols quite useful, but I haven't found the equivalent of a TCK type list of intents which absolutely must be supported, and examples of what apps do different handsets.
You can use the ternary operator easily:
{{ $usersType ? $usersType : '' }}
You can do this using Escape Sequence.
\"
So you will have to write something like this :
String name = "\"john\"";
You can learn about Escape Sequences from here.
If by applications you mean multiple processes then yes but generally NO. For example Apache server runs multiple processes on same port (generally 80).It's done by designating one of the process to actually bind to the port and then use that process to do handovers to various processes which are accepting connections.
You just need to display the div with id #menu
as flex container like this:
#menu{
width: 800px;
display: flex;
justify-content: space-between;
}
That's a good trick.
One other suggestion is to use memory efficient objects wherever possible: for instance, use a matrix instead of a data.frame.
This doesn't really address memory management, but one important function that isn't widely known is memory.limit(). You can increase the default using this command, memory.limit(size=2500), where the size is in MB. As Dirk mentioned, you need to be using 64-bit in order to take real advantage of this.
Here is the best way I've found to add read-only users (using PostgreSQL 9.0 or newer):
$ sudo -upostgres psql postgres
postgres=# CREATE ROLE readonly WITH LOGIN ENCRYPTED PASSWORD '<USE_A_NICE_STRONG_PASSWORD_PLEASE';
postgres=# GRANT SELECT ON ALL TABLES IN SCHEMA public TO readonly;
Then log in to all related machines (master + read-slave(s)/hot-standby(s), etc..) and run:
$ echo "hostssl <PUT_DBNAME_HERE> <PUT_READONLY_USERNAME_HERE> 0.0.0.0/0 md5" | sudo tee -a /etc/postgresql/9.2/main/pg_hba.conf
$ sudo service postgresql reload
CD-Keys aren't much of a security for any non-networked stuff, so technically they don't need to be securely generated. If you're on .net, you can almost go with Guid.NewGuid().
Their main use nowadays is for the Multiplayer component, where a server can verify the CD Key. For that, it's unimportant how securely it was generated as it boils down to "Lookup whatever is passed in and check if someone else is already using it".
That being said, you may want to use an algorhithm to achieve two goals:
That being said, you still want a large distribution and some randomness to avoid a pirate simply guessing a valid key (that's valid in your database but still in a box on a store shelf) and screwing over a legitimate customer who happens to buy that box.
public static String removechar(String fromString, Character character) {
int indexOf = fromString.indexOf(character);
if(indexOf==-1)
return fromString;
String front = fromString.substring(0, indexOf);
String back = fromString.substring(indexOf+1, fromString.length());
return front+back;
}
string connectionString= ServerName + DatabaseName + SecurityType;
using (SqlConnection connection = new SqlConnection(connectionString))
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(connection)) {
connection.Open();
bulkCopy.DestinationTableName = "TableName";
try {
bulkCopy.WriteToServer(dataTableName);
} catch (Exception e) {
Console.Write(e.Message);
}
}
Please note that the structure of the database table and the table name should be the same or it will throw an exception.
If you are using Java, you could just replace the x00 characters before the insert like following:
myValue.replaceAll("\u0000", "")
The solution was provided and explained by Csaba in following post:
https://www.postgresql.org/message-id/1171970019.3101.328.camel%40coppola.muc.ecircle.de
Respectively:
in Java you can actually have a "0x0" character in your string, and that's valid unicode. So that's translated to the character 0x0 in UTF8, which in turn is not accepted because the server uses null terminated strings... so the only way is to make sure your strings don't contain the character '\u0000'.
Although there is nothing wrong with the other solutions presented, you could simplify and greatly escalate your solutions by using python's excellent library pandas.
Pandas is a library for handling data in Python, preferred by many Data Scientists.
Pandas has a simplified CSV interface to read and parse files, that can be used to return a list of dictionaries, each containing a single line of the file. The keys will be the column names, and the values will be the ones in each cell.
In your case:
import pandas
def create_dictionary(filename):
my_data = pandas.DataFrame.from_csv(filename, sep='\t', index_col=False)
# Here you can delete the dataframe columns you don't want!
del my_data['B']
del my_data['D']
# ...
# Now you transform the DataFrame to a list of dictionaries
list_of_dicts = [item for item in my_data.T.to_dict().values()]
return list_of_dicts
# Usage:
x = create_dictionary("myfile.csv")
RFC 3066 gives the details of the allowed values (emphasis and links added):
All 2-letter subtags are interpreted as ISO 3166 alpha-2 country codes from [ISO 3166], or subsequently assigned by the ISO 3166 maintenance agency or governing standardization bodies, denoting the area to which this language variant relates.
I interpret that as meaning any valid (according to ISO 3166) 2-letter code is valid as a subtag. The RFC goes on to state:
Tags with second subtags of 3 to 8 letters may be registered with IANA, according to the rules in chapter 5 of this document.
By the way, that looks like a typo, since chapter 3 seems to relate to the the registration process, not chapter 5.
A quick search for the IANA registry reveals a very long list, of all the available language subtags. Here's one example from the list (which would be used as en-scouse
):
Type: variant
Subtag: scouse
Description: Scouse
Added: 2006-09-18
Prefix: en
Comments: English Liverpudlian dialect known as 'Scouse'
There are all sorts of subtags available; a quick scroll has already revealed fr-1694acad
(17th century French).
The usefulness of some of these (I would say the vast majority of these) tags, when it comes to documents designed for display in the browser, is limited. The W3C Internationalization specification simply states:
Browsers and other applications can use information about the language of content to deliver to users the most appropriate information, or to present information to users in the most appropriate way. The more content is tagged and tagged correctly, the more useful and pervasive such applications will become.
I'm struggling to find detailed information on how browsers behave when encountering different language tags, but they are most likely going to offer some benefit to those users who use a screen reader, which can use the tag to determine the language/dialect/accent in which to present the content.
1) You can use the !important
rule, like this:
.selected
{
background-color:red !important;
}
See http://www.w3.org/TR/CSS2/cascade.html#important-rules for more info.
2) In your example you can also get the red background by using ul.nav li.selected
instead of just .selected
. This makes the selector more specific.
See http://www.w3.org/TR/CSS2/cascade.html#specificity for more info.
Style the label with CSS and use pointer events :
<label>
<select>
<option value="0">Zero</option>
<option value="1">One</option>
</select>
</label>
and the relative CSS is
label:after {
content:'\25BC';
display:inline-block;
color:#000;
background-color:#fff;
margin-left:-17px; /* remove the damn :after space */
pointer-events:none; /* let the click pass trough */
}
I just used a down arrow here, but you can set a block with a background image. Here is a ugly fiddle sample: https://jsfiddle.net/1rofzz89/
I was inserting script
tags dynamically with this usual alternative to eval
and simply set a global property currentComponentScript
right before adding to the DOM.
const old = el.querySelector("script")[0];
const replacement = document.createElement("script");
replacement.setAttribute("type", "module");
replacement.appendChild(document.createTextNode(old.innerHTML));
window.currentComponentScript = replacement;
old.replaceWith(replacement);
Doesn't work in a loop though. The DOM doesn't run the scripts until the next macrotask so a batch of them will only see the last value set. You'd have to setTimeout
the whole paragraph, and then setTimeout
the next one after the previous finishes. I.e. chain the setTimeouts, not just call setTimeout
multiple times in a row from a loop.
If possible use Visual Studio. The Microsoft SQL Server Data Tools (SSDT) bring a built in functionality for this since the March 2014 release:
Note: Be careful, the "View Data" window is just like SSMS "Edit Top 200 Rows"- you can edit data right away
(Tested with Visual Studio 2015 with Microsoft SQL Server Data Tools (SSDT) Version 14.0.60812.0 and Microsoft SQL Server 2012)
Ran into this today at work. An admin thought it prudent to hard code Python 2.7 as the PYSPARK_PYTHON
and PYSPARK_DRIVER_PYTHON
in $SPARK_HOME/conf/spark-env.sh
. Needless to say this broke all of our jobs that utilize any other python versions or environments (which is > 90% of our jobs). @PhillipStich points out correctly that you may not always have write permissions for this file, as is our case. While setting the configuration in the spark-submit
call is an option, another alternative (when running in yarn/cluster mode) is to set the SPARK_CONF_DIR
environment variable to point to another configuration script. There you could set your PYSPARK_PYTHON and any other options you may need. A template can be found in the spark-env.sh source code on github.
I thought that the most intuitive single file upload process was to replace the previous file upon a new entry.
$(".drop-image").dropzone({
url: '/cart?upload-engraving=true',
maxFiles: 1,
maxfilesexceeded: function(file) {
this.removeAllFiles();
this.addFile(file);
}
})
Try a simple way:
if($('input[readonly="readonly"]')){
alert("foo");
}
Also, you can do like this.
List<String> list = Arrays.asList("One", "Two", "Three");
String result = String.join(", ", list);
System.out.println(result);
Go to the file location where the POM is stored and open cmd. Then type "mvn --v" to check the maven version and java runtime provided. Check runtime attribute and if it is "C:\Program Files\Java\jre1.8.0_191" or even close to a JRE, go to environment variables and add a new "system variable" called "JAVA_HOME" with a value "C:\Program Files\Java\jdk1.8.0_191".
Reopen the cmd and then "clean install" the project.
How about if you use grep instead of find?
ls | grep .txt$ > out.txt
Now you can read this file and the filenames are in the form of a list.
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
I had similar problem. I needed to write down csv file on driver while I was connect to cluster in client mode.
I wanted to reuse the same CSV parsing code as Apache Spark to avoid potential errors.
I checked spark-csv code and found code responsible for converting dataframe into raw csv RDD[String]
in com.databricks.spark.csv.CsvSchemaRDD
.
Sadly it is hardcoded with sc.textFile
and the end of relevant method.
I copy-pasted that code and removed last lines with sc.textFile
and returned RDD directly instead.
My code:
/*
This is copypasta from com.databricks.spark.csv.CsvSchemaRDD
Spark's code has perfect method converting Dataframe -> raw csv RDD[String]
But in last lines of that method it's hardcoded against writing as text file -
for our case we need RDD.
*/

The thing i don't like about iValidate is it seems to only run AFTER all other validation.
Additionally, at least in our site, it would run again during a save attempt. I would suggest you simply create a function and place all your validation code in that. Alternately for websites, you could have your "special" validation in the controller after the model is created. Example:
public ActionResult Update([DataSourceRequest] DataSourceRequest request, [Bind(Exclude = "Terminal")] Driver driver)
{
if (db.Drivers.Where(m => m.IDNumber == driver.IDNumber && m.ID != driver.ID).Any())
{
ModelState.AddModelError("Update", string.Format("ID # '{0}' is already in use", driver.IDNumber));
}
if (db.Drivers.Where(d => d.CarrierID == driver.CarrierID
&& d.FirstName.Equals(driver.FirstName, StringComparison.CurrentCultureIgnoreCase)
&& d.LastName.Equals(driver.LastName, StringComparison.CurrentCultureIgnoreCase)
&& (driver.ID == 0 || d.ID != driver.ID)).Any())
{
ModelState.AddModelError("Update", "Driver already exists for this carrier");
}
if (ModelState.IsValid)
{
try
{
public void reverse() {
head = reverseNodes(null, head);
}
private Node reverseNodes(Node prevNode, Node currentNode) {
if (currentNode == null)
return prevNode;
Node nextNode = currentNode.next;
currentNode.next = prevNode;
return reverseNodes(currentNode, nextNode);
}
get DLImageLoader and try folowing code
[DLImageLoader loadImageFromURL:imageURL
completed:^(NSError *error, NSData *imgData) {
imageView.image = [UIImage imageWithData:imgData];
[imageView setContentMode:UIViewContentModeCenter];
}];
Another typical real-world example of using DLImageLoader, which may help someone...
PFObject *aFacebookUser = [self.fbFriends objectAtIndex:thisRow];
NSString *facebookImageURL = [NSString stringWithFormat:
@"http://graph.facebook.com/%@/picture?type=large",
[aFacebookUser objectForKey:@"id"] ];
__weak UIImageView *loadMe = self.userSmallAvatarImage;
// ~~note~~ you my, but usually DO NOT, want a weak ref
[DLImageLoader loadImageFromURL:facebookImageURL
completed:^(NSError *error, NSData *imgData)
{
if ( loadMe == nil ) return;
if (error == nil)
{
UIImage *image = [UIImage imageWithData:imgData];
image = [image ourImageScaler];
loadMe.image = image;
}
else
{
// an error when loading the image from the net
}
}];
As I mention above another great library to consider these days is Haneke (unfortunately it's not as lightweight).
If you are using gcc
you can give designated initializers
in object creation.
typedef struct
{
int id=0;
char* name="none";
}employee;
employee e =
{
.id = 0;
.name = "none";
};
Or , simply use like array initialization.
employee e = {0 , "none"};
lodash and ES5
var song = _.find(songs, {id:id});
lodash and ES6
let song = _.find(songs, {id});
docs at https://lodash.com/docs#find
Inline items cannot have a width. You have to use display: block
or display:inline-block
, but the latter is not supported everywhere.
You can do something like this to automatically register them all into a collection with which to then easily convert the integers to the corresponding enum. (BTW, adding them to the map in the enum constructor is not allowed. It's nice to learn new things even after many years of using Java. :)
public enum PcapLinkType {
DLT_NULL(0),
DLT_EN10MB(1),
DLT_EN3MB(2),
DLT_AX25(3),
/*snip, 200 more enums, not always consecutive.*/
DLT_UNKNOWN(-1);
private static final Map<Integer, PcapLinkType> typesByValue = new HashMap<Integer, PcapLinkType>();
static {
for (PcapLinkType type : PcapLinkType.values()) {
typesByValue.put(type.value, type);
}
}
private final int value;
private PcapLinkType(int value) {
this.value = value;
}
public static PcapLinkType forValue(int value) {
return typesByValue.get(value);
}
}
public class TimeDelay{
public static void main(String args[]) {
try {
while (true) {
System.out.println(new String("Hello world"));
Thread.sleep(3 * 1000); // every 3 seconds
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
x=[1,2,3,4,5]
sum=0
for s in range(0,len(x)):
sum=sum+x[s]
print sum
Have a look at Control.BeginInvoke method. The point is to never update UI controls from another thread. BeginInvoke will dispatch the call to the UI thread of the control (in your case, the Form).
To grab the form, remove the static modifier from the sample function and use this.BeginInvoke() as shown in the examples from MSDN.
Access-Engine does not support
SELECT count(DISTINCT....) FROM ...
You have to do it like this:
SELECT count(*)
FROM
(SELECT DISTINCT Name FROM table1)
Its a little workaround... you're counting a DISTINCT selection.
The reason the encoded array is longer by about a quarter is that base-64 encoding uses only six bits out of every byte; that is its reason of existence - to encode arbitrary data, possibly with zeros and other non-printable characters, in a way suitable for exchange through ASCII-only channels, such as e-mail.
The way you get your original array back is by using Convert.FromBase64String
:
byte[] temp_backToBytes = Convert.FromBase64String(temp_inBase64);
In Python 3 (I haven't tried this in Python 2), you can also simply do
with open('output.csv','w',newline='') as f:
writer=csv.writer(f)
writer.writerow(mystuff)
...
as per documentation.
More on this in the doc's footnote:
If newline='' is not specified, newlines embedded inside quoted fields will not be interpreted correctly, and on platforms that use \r\n linendings on write an extra \r will be added. It should always be safe to specify newline='', since the csv module does its own (universal) newline handling.
Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.
UPD 19.03.2019 Here is a version for browser on GitHub.
As previously mentioned, the FileSystem and File APIs, along with the FileWriter API, can be used to read and write files from the context of a browser tab/window to a client machine.
There are several things pertaining to the FileSystem and FileWriter APIs which you should be aware of, some of which were mentioned, but are worth repeating:
Here are simple examples of how the APIs are used, directly and indirectly, in tandem to do these things:
Write file:
bakedGoods.set({
data: [{key: "testFile", value: "Hello world!", dataFormat: "text/plain"}],
storageTypes: ["fileSystem"],
options: {fileSystem:{storageType: Window.PERSISTENT}},
complete: function(byStorageTypeStoredItemRangeDataObj, byStorageTypeErrorObj){}
});
Read file:
bakedGoods.get({
data: ["testFile"],
storageTypes: ["fileSystem"],
options: {fileSystem:{storageType: Window.PERSISTENT}},
complete: function(resultDataObj, byStorageTypeErrorObj){}
});
Using the raw File, FileWriter, and FileSystem APIs
Write file:
function onQuotaRequestSuccess(grantedQuota)
{
function saveFile(directoryEntry)
{
function createFileWriter(fileEntry)
{
function write(fileWriter)
{
var dataBlob = new Blob(["Hello world!"], {type: "text/plain"});
fileWriter.write(dataBlob);
}
fileEntry.createWriter(write);
}
directoryEntry.getFile(
"testFile",
{create: true, exclusive: true},
createFileWriter
);
}
requestFileSystem(Window.PERSISTENT, grantedQuota, saveFile);
}
var desiredQuota = 1024 * 1024 * 1024;
var quotaManagementObj = navigator.webkitPersistentStorage;
quotaManagementObj.requestQuota(desiredQuota, onQuotaRequestSuccess);
Read file:
function onQuotaRequestSuccess(grantedQuota)
{
function getfile(directoryEntry)
{
function readFile(fileEntry)
{
function read(file)
{
var fileReader = new FileReader();
fileReader.onload = function(){var fileData = fileReader.result};
fileReader.readAsText(file);
}
fileEntry.file(read);
}
directoryEntry.getFile(
"testFile",
{create: false},
readFile
);
}
requestFileSystem(Window.PERSISTENT, grantedQuota, getFile);
}
var desiredQuota = 1024 * 1024 * 1024;
var quotaManagementObj = navigator.webkitPersistentStorage;
quotaManagementObj.requestQuota(desiredQuota, onQuotaRequestSuccess);
Though the FileSystem and FileWriter APIs are no longer on the standards track, their use can be justified in some cases, in my opinion, because:
Whether "some cases" encompasses your own, however, is for you to decide.
*BakedGoods is maintained by none other than this guy right here :)
As mentioned in other answers, the exception is being thrown because each call to registerReceiver
is not being matched by exactly one call to unregisterReceiver
. Why not?
An Activity
does not always have a matching onDestroy
call for every onCreate
call. If the system runs out of memory, your app is evicted without calling onDestroy
.
The correct place to put a registerReceiver
call is in the onResume
call, and unregisterReceiver
in onPause
. This pair of calls is always matched. See the Activity lifecycle diagram for more details.
http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle
Your code would change to:
SharedPreferences mPref
IntentFilter mFilter;
@Override
public void onCreate(){
super.onCreate();
mPref = PreferenceManager.getDefaultSharedPreferences(this);
mFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
filter.addAction(Intent.ACTION_POWER_CONNECTED);
filter.addAction(Intent.ACTION_POWER_DISCONNECTED);
}
@Override
public void onResume() {
registerReceiver(batteryNotifyReceiver,mFilter);
mPref.registerOnSharedPreferenceChangeListener(this);
}
@Override
public void onPause(){
unregisterReceiver(batteryNotifyReceiver, mFilter);
mPref.unregisterOnSharedPreferenceChangeListener(this);
}
Use:
$name = jdmonthname(gregoriantojd($monthNumber, 1, 1), CAL_MONTH_GREGORIAN_LONG);
z-index
only applies to elements that have been given an explicit position. Add position:relative
to #popupContent and you should be good to go.
I know this is old thread already. but maybe someone will look for solution. And here's what I use and the easiest way
public static string FormatFileSize(long bytes)
{
var unit = 1024;
if (bytes < unit) { return $"{bytes} B"; }
var exp = (int)(Math.Log(bytes) / Math.Log(unit));
return $"{bytes / Math.Pow(unit, exp):F2} {("KMGTPE")[exp - 1]}B";
}
Get folder size (for example usage)
public static long GetFolderSize(string path, string ext, bool AllDir)
{
var option = AllDir ? SearchOption.AllDirectories : SearchOption.TopDirectoryOnly;
return new DirectoryInfo(path).EnumerateFiles("*" + ext, option).Sum(file => file.Length);
}
EXAMPLE USAGE:
public static void TEST()
{
string folder = @"C:\Users\User\Videos";
var bytes = GetFolderSize(folder, "mp4", true); //or GetFolderSize(folder, "mp4", false) to get all single folder only
var totalFileSize = FormatFileSize(bytes);
Console.WriteLine(totalFileSize);
}
The proof answers are good, but I always have to do a few iterations by hand to really convince myself. So I drew out a small calling tree on my whiteboard, and started counting the nodes. I split my counts out into total nodes, leaf nodes, and interior nodes. Here's what I got:
IN | OUT | TOT | LEAF | INT
1 | 1 | 1 | 1 | 0
2 | 1 | 1 | 1 | 0
3 | 2 | 3 | 2 | 1
4 | 3 | 5 | 3 | 2
5 | 5 | 9 | 5 | 4
6 | 8 | 15 | 8 | 7
7 | 13 | 25 | 13 | 12
8 | 21 | 41 | 21 | 20
9 | 34 | 67 | 34 | 33
10 | 55 | 109 | 55 | 54
What immediately leaps out is that the number of leaf nodes is fib(n)
. What took a few more iterations to notice is that the number of interior nodes is fib(n) - 1
. Therefore the total number of nodes is 2 * fib(n) - 1
.
Since you drop the coefficients when classifying computational complexity, the final answer is ?(fib(n))
.
Use .container-fluid
when you want your page to shapeshift with every little difference in its viewport size.
Use .container
when you want your page to shapeshift to only 4 kinds of sizes, which are also known as "breakpoints".
The breakpoints corresponding to their sizes are:
The phone number data annotation attribute is for the data type, which is not related to the data display format. It's just a misunderstanding. Phone number means you can accept numbers and symbols used for phone numbers for this locale, but is not checking the format, length, range, or else. For display string format use the javascript to have a more dynamic user interaction, or a plugin for MVC mask, or just use a display format string properly.
If you are new to MVC programming put this code at the very end of your view file (.cshtml) and see the magic:
<script src="https://code.jquery.com/jquery-3.5.1.min.js" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#the_id_of_your_field_control").keyup(function () {
$(this).val($(this).val().replace(/^(\d{2})(\d{5})(\d{4})+$/, "($1) $2-$3"));
});
});
</script>
This format is currently used for mobile phones in Brazil. Adapt for your standard.
This will add the parenthesis and spaces to your field, which will increase the string length of your input data. If you want to save just the numbers you will have to trim out the non-numbers from the string before saving.
For adding item in Spinner, you can do one thing, try to create an adapter and then add/remove items into the adapter, then you can easily bind that adapter to spinner by using setAdapter()
method.
Here is an example:
spinner.setAdapter(adapter);
adapter.add(item1);
adapter.add(item2);
adapter.add(item3);
adapter.add(item4);
adapter.add(item5);
adapter.notifyDataSetChanged();
spinner.setAdapter(adapter);
use mkdirs() instead of mkdir()..it worked for me :)
File folder = new File(Environment.getExternalStorageDirectory()+"/Saved CGPA");
if(!folder.exists()){
if(folder.mkdirs())
Toast.makeText(this, "New Folder Created", Toast.LENGTH_SHORT).show();
}
File sdCardFile = new File(Environment.getExternalStorageDirectory()+"/Saved CGPA/cgpa.html");
Use the not
boolean operator:
nyval = not myval
not
returns a boolean value (True
or False
):
>>> not 1
False
>>> not 0
True
If you must have an integer, cast it back:
nyval = int(not myval)
However, the python bool
type is a subclass of int
, so this may not be needed:
>>> int(not 0)
1
>>> int(not 1)
0
>>> not 0 == 1
True
>>> not 1 == 0
True
You can try below command, which describes the,
ng -> Angular
g -> Generate
c -> Component
-m -> Module
Then your command will be like:
ng g c user/userComponent -m user.module
i wanted to mention Jailbreak specifically (GitHub):
Jailbreak
Jailbreak is a tool for exporting certificates marked as non-exportable from the Windows certificate store. This can help when you need to extract certificates for backup or testing. You must have full access to the private key on the filesystem in order for jailbreak to work.
Prerequisites: Win32
This is what I did to move a test file from the downloads to the desktop. I hope its useful.
private void button1_Click(object sender, EventArgs e)//Copy files to the desktop
{
string sourcePath = @"C:\Users\UsreName\Downloads";
string targetPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string[] shortcuts = {
"FileCopyTest.txt"};
try
{
listbox1.Items.Add("Starting: Copy shortcuts to dektop.");
for (int i = 0; i < shortcuts.Length; i++)
{
if (shortcuts[i]!= null)
{
File.Copy(Path.Combine(sourcePath, shortcuts[i]), Path.Combine(targetPath, shortcuts[i]), true);
listbox1.Items.Add(shortcuts[i] + " was moved to desktop!");
}
else
{
listbox1.Items.Add("Shortcut " + shortcuts[i] + " Not found!");
}
}
}
catch (Exception ex)
{
listbox1.Items.Add("Unable to Copy file. Error : " + ex);
}
}
Use the size()
function.
>> size(A,2)
Ans =
3
The second argument specifies the dimension of which number of elements are required which will be '2' if you want the number of columns.
If you want to edit and reissue a request that you have captured in Chrome Developer Tools' Network tab:
Name
of the requestCopy > Copy as cURL
Shorter, more reliable and more performant than the current best-voted answer:
const getCookieValue = (name) => (
document.cookie.match('(^|;)\\s*' + name + '\\s*=\\s*([^;]+)')?.pop() || ''
)
A performance comparison of various approaches is shown here:
http://jsperf.com/get-cookie-value-regex-vs-array-functions
Some notes on approach:
The regex approach is not only the fastest in most browsers, it yields the shortest function as well. Additionally it should be pointed out that according to the official spec (RFC 2109), the space after the semicolon which separates cookies in the document.cookie is optional and an argument could be made that it should not be relied upon. Additionally, whitespace is allowed before and after the equals sign (=) and an argument could be made that this potential whitespace should be factored into any reliable document.cookie parser. The regex above accounts for both of the above whitespace conditions.
Thank guys for showing all those examples. I was still having trouble with my contact page on small media screens like below 480px after trying your examples. Bootstrap kept inserting height: auto
.
Element Inspector / Devtools will show the height in:
element.style {
}
In my case I was seeing: section#contact.contact-container | 303 x 743
in the browser window.
So the following full-length works to eliminate the issue:
$('section#contact.contact-container').height('');
As other answers pointed out, it is most likely generated by some tool.
But if I were the original author of the file, my answer would be: Consistency.
If I am not allowed to put double quotes in my attributes, why put them in the element's content ? Why do these specs always have these exceptional cases ..
If I had to write the HTML spec, I would say All double quotes need to be encoded
. Done.
Today it is like In attribute values we need to encode double quotes, except when the attribute value itself is defined by single quotes. In the content of elements, double quotes can be, but are not required to be, encoded.
(And I am surely forgetting some cases here).
Double quotes are a keyword of the spec, encode them. Lesser/greater than are a keyword of the spec, encode them. etc..
http://www.cplusplus.com/reference/std/iterator/ has a handy chart that details the specs of § 24.2.2 of the C++11 standard. Basically, the iterators have tags that describe the valid operations, and the tags have a hierarchy. Below is purely symbolic, these classes don't actually exist as such.
iterator {
iterator(const iterator&);
~iterator();
iterator& operator=(const iterator&);
iterator& operator++(); //prefix increment
reference operator*() const;
friend void swap(iterator& lhs, iterator& rhs); //C++11 I think
};
input_iterator : public virtual iterator {
iterator operator++(int); //postfix increment
value_type operator*() const;
pointer operator->() const;
friend bool operator==(const iterator&, const iterator&);
friend bool operator!=(const iterator&, const iterator&);
};
//once an input iterator has been dereferenced, it is
//undefined to dereference one before that.
output_iterator : public virtual iterator {
reference operator*() const;
iterator operator++(int); //postfix increment
};
//dereferences may only be on the left side of an assignment
//once an output iterator has been dereferenced, it is
//undefined to dereference one before that.
forward_iterator : input_iterator, output_iterator {
forward_iterator();
};
//multiple passes allowed
bidirectional_iterator : forward_iterator {
iterator& operator--(); //prefix decrement
iterator operator--(int); //postfix decrement
};
random_access_iterator : bidirectional_iterator {
friend bool operator<(const iterator&, const iterator&);
friend bool operator>(const iterator&, const iterator&);
friend bool operator<=(const iterator&, const iterator&);
friend bool operator>=(const iterator&, const iterator&);
iterator& operator+=(size_type);
friend iterator operator+(const iterator&, size_type);
friend iterator operator+(size_type, const iterator&);
iterator& operator-=(size_type);
friend iterator operator-(const iterator&, size_type);
friend difference_type operator-(iterator, iterator);
reference operator[](size_type) const;
};
contiguous_iterator : random_access_iterator { //C++17
}; //elements are stored contiguously in memory.
You can either specialize std::iterator_traits<youriterator>
, or put the same typedefs in the iterator itself, or inherit from std::iterator
(which has these typedefs). I prefer the second option, to avoid changing things in the std
namespace, and for readability, but most people inherit from std::iterator
.
struct std::iterator_traits<youriterator> {
typedef ???? difference_type; //almost always ptrdiff_t
typedef ???? value_type; //almost always T
typedef ???? reference; //almost always T& or const T&
typedef ???? pointer; //almost always T* or const T*
typedef ???? iterator_category; //usually std::forward_iterator_tag or similar
};
Note the iterator_category should be one of std::input_iterator_tag
, std::output_iterator_tag
, std::forward_iterator_tag
, std::bidirectional_iterator_tag
, or std::random_access_iterator_tag
, depending on which requirements your iterator satisfies. Depending on your iterator, you may choose to specialize std::next
, std::prev
, std::advance
, and std::distance
as well, but this is rarely needed. In extremely rare cases you may wish to specialize std::begin
and std::end
.
Your container should probably also have a const_iterator
, which is a (possibly mutable) iterator to constant data that is similar to your iterator
except it should be implicitly constructable from a iterator
and users should be unable to modify the data. It is common for its internal pointer to be a pointer to non-constant data, and have iterator
inherit from const_iterator
so as to minimize code duplication.
My post at Writing your own STL Container has a more complete container/iterator prototype.
Is there a way to have placeholders, like ? for column names? For example SELECT ? FROM TABLEA GROUP BY ?
Use dynamic query as below:
String queryString = "SELECT "+ colName+ " FROM TABLEA GROUP BY "+ colName;
If I want to simply run the above query and get a List what is the best way?
List<String> data = getJdbcTemplate().query(query, new RowMapper<String>(){
public String mapRow(ResultSet rs, int rowNum)
throws SQLException {
return rs.getString(1);
}
});
EDIT: To Stop SQL Injection, check for non word characters in the colName as :
Pattern pattern = Pattern.compile("\\W");
if(pattern.matcher(str).find()){
//throw exception as invalid column name
}
I have a slightly different way of doing this than the accepted answer. This way you can avoid using GROUP_CONCAT which has a limit of 1024 characters and will not work if you have a lot of fields.
SET @sql = '';
SELECT
@sql := CONCAT(@sql,if(@sql='','',', '),temp.output)
FROM
(
SELECT
DISTINCT
CONCAT(
'MAX(IF(pa.fieldname = ''',
fieldname,
''', pa.fieldvalue, NULL)) AS ',
fieldname
) as output
FROM
product_additional
) as temp;
SET @sql = CONCAT('SELECT p.id
, p.name
, p.description, ', @sql, '
FROM product p
LEFT JOIN product_additional AS pa
ON p.id = pa.id
GROUP BY p.id');
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
I tried function toFixed(2) many times. Every time console shows "toFixed() is not a function".
but how I resolved is By using Math.round()
eg:
if ($(this).attr('name') == 'time') {
var value = parseFloat($(this).val());
value = Math.round(value*100)/100; // 10 defines 1 decimals, 100 for 2, 1000 for 3
alert(value);
}
this thing surely works for me and it might help you guys too...
You can try this :
To open Gallery :
private void browseImage() {
try {
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, GALLERY_IMAGE_PICK); //GALLERY_IMAGE_PICK it is a string
} catch (Exception e) {}
}
To open Camera :
private void captureImage() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
Arrays have numerical indexes. So,
a = new Array();
a['a1']='foo';
a['a2']='bar';
and
b = new Array(2);
b['b1']='foo';
b['b2']='bar';
are not adding elements to the array, but adding .a1
and .a2
properties to the a
object (arrays are objects too). As further evidence, if you did this:
a = new Array();
a['a1']='foo';
a['a2']='bar';
console.log(a.length); // outputs zero because there are no items in the array
Your third option:
c=['c1','c2','c3'];
is assigning the variable c
an array with three elements. Those three elements can be accessed as: c[0]
, c[1]
and c[2]
. In other words, c[0] === 'c1'

Javascript does not use its array functionality for what other languages call associative arrays where you can use any type of key in the array. You can implement most of the functionality of an associative array by just using an object in javascript where each item is just a property like this.
a = {};
a['a1']='foo';
a['a2']='bar';
It is generally a mistake to use an array for this purpose as it just confuses people reading your code and leads to false assumptions about how the code works.

I solved my issue on Bing Maps WPF on my project Using CalculateRoute (). The solution in my case was setting the maxReceivedMessageSize and maxReceivedMessageSize on attribute "httpTransport" for "customBinding" section .
I set in the applications.config file (es. myApp.config) this configuration:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IGeocodeService" />
<binding name="BasicHttpBinding_IRouteService" />
</basicHttpBinding>
<customBinding>
<binding name="CustomBinding_IGeocodeService">
<binaryMessageEncoding />
<httpTransport manualAddressing="false" maxBufferPoolSize="524288"
maxReceivedMessageSize="2147483647" allowCookies="false" authenticationScheme="Anonymous"
bypassProxyOnLocal="false" decompressionEnabled="true" hostNameComparisonMode="StrongWildcard"
keepAliveEnabled="true" maxBufferSize="2147483647" proxyAuthenticationScheme="Anonymous"

Or in ES6
values.reduce((a, b) => a + b),
example:
[1,2,3].reduce((a, b)=>a+b) // return 6
Assuming you have a list of object of type Person, using Lambda expression, you can sort the last names of users for instance by doing the following:
import java.util.Arrays;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
class Person {
private String firstName;
private String lastName;
public Person(String firstName, String lastName){
this.firstName = firstName;
this.lastName = lastName;
}
public String getLastName(){
return this.lastName;
}
public String getFirstName(){
return this.firstName;
}
@Override
public String toString(){
return "Person: "+ this.getFirstName() + " " + this.getLastName();
}
}
class TestSort {
public static void main(String[] args){
List<Person> people = Arrays.asList(
new Person("John", "Max"),
new Person("Coolio", "Doe"),
new Person("Judith", "Dan")
);
//Making use of lambda expression to sort the collection
people.sort((p1, p2)->p1.getLastName().compareTo(p2.getLastName()));
//Print sorted
printPeople(people);
}
public static void printPeople(List<Person> people){
for(Person p : people){
System.out.println(p);
}
}
}
With this query you can execute any stored procedure(With or Without output parameter):
DECLARE @temp varchar(100)
EXEC my_sp
@parameter1 = 1,
@parameter2 = 2,
@parameter3 = @temp output,
@parameter4 = 3,
@parameter5 = 4
PRINT @temp
Here datatype of @temp should be same as @parameter3 within SP.
Hope this helps..
Seeing your loop for sending emails and the error which you provided there is only solution.
Declare the mail object out of the loop and assign fromaddress
out of the loop which you are using for sending mails. The fromaddress
field is getting assigned again and again in the loop that is your problem.
I would change your service layer to:
public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
return Task.Run(() =>
{
return _service.Process<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}
}
as you have it, you are still running your _service.Process
call synchronously, and gaining very little or no benefit from awaiting it.
With this approach, you are wrapping the potentially slow call in a Task
, starting it, and returning it to be awaited. Now you get the benefit of awaiting the Task
.
There is no :unchecked pseudo class however if you use the :checked pseudo class and the sibling selector you can differentiate between both states. I believe all of the latest browsers support the :checked pseudo class, you can find more info from this resource: http://www.whatstyle.net/articles/18/pretty_form_controls_with_css
Your going to get better browser support with jquery... you can use a click function to detect when the click happens and if its checked or not, then you can add a class or remove a class as necessary...
First of all, you should never use the money datatype. If you do any calculations you will get truncated results. Run the following to see what I mean
DECLARE
@mon1 MONEY,
@mon2 MONEY,
@mon3 MONEY,
@mon4 MONEY,
@num1 DECIMAL(19,4),
@num2 DECIMAL(19,4),
@num3 DECIMAL(19,4),
@num4 DECIMAL(19,4)
SELECT
@mon1 = 100, @mon2 = 339, @mon3 = 10000,
@num1 = 100, @num2 = 339, @num3 = 10000
SET @mon4 = @mon1/@mon2*@mon3
SET @num4 = @num1/@num2*@num3
SELECT @mon4 AS moneyresult,
@num4 AS numericresult
Output: 2949.0000 2949.8525
Now to answer your question (it was a little vague), the money datatype always has two places after the decimal point. Use the integer datatype if you don't want the fractional part or convert to int.
Perhaps you want to use the decimal or numeric datatype?
Type | Approx. Length | Exact Max. Length Allowed
-----------------------------------------------------------
TINYTEXT | 256 Bytes | 255 characters
TEXT | 64 Kilobytes | 65,535 characters
MEDIUMTEXT | 16 Megabytes | 16,777,215 characters
LONGTEXT | 4 Gigabytes | 4,294,967,295 characters
Basically, it's like:
"Exact Max. Length Allowed" = "Approx. Length" in bytes - 1
Note: If using multibyte characters (like Arabic, where each Arabic character takes 2 bytes), the column "Exact Max. Length Allowed" for TINYTEXT
can hold be up to 127 Arabic characters (Note: space, dash, underscore, and other such characters, are 1-byte characters).
Try specifying exactly the modal that the button should close with data-target. So your button should look like the following -
<button class="close" data-dismiss="modal" data-target="#myModal">×</button>
Also, you should only need bootstrap.modal.js so you can safely remove the others.
Edit: if this doesn't work then remove the visible-phone class and test it on your PC browser instead of the phone. This will show whether you are getting javascript errors or if its a compatibility issue for example.
Edit: Demo code

I've created tutorial on my page https://madebydenis.com/ajax-load-posts-on-wordpress/ about implementing this on Twenty Sixteen theme, so feel free to check it out :)
I've tested this on Twenty Fifteen and it's working, so it should be working for you.
In index.php (assuming that you want to show the posts on the main page, but this should work even if you put it in a page template) I put:
<div id="ajax-posts" class="row">
<?php
$postsPerPage = 3;
$args = array(
'post_type' => 'post',
'posts_per_page' => $postsPerPage,
'cat' => 8
);
$loop = new WP_Query($args);
while ($loop->have_posts()) : $loop->the_post();
?>
<div class="small-12 large-4 columns">
<h1><?php the_title(); ?></h1>
<p><?php the_content(); ?></p>
</div>
<?php
endwhile;
wp_reset_postdata();
?>
</div>
<div id="more_posts">Load More</div>
This will output 3 posts from category 8 (I had posts in that category, so I used it, you can use whatever you want to). You can even query the category you're in with
$cat_id = get_query_var('cat');
This will give you the category id to use in your query. You could put this in your loader (load more div), and pull with jQuery like
<div id="more_posts" data-category="<?php echo $cat_id; ?>">>Load More</div>
And pull the category with
var cat = $('#more_posts').data('category');
But for now, you can leave this out.
Next in functions.php I added
wp_localize_script( 'twentyfifteen-script', 'ajax_posts', array(
'ajaxurl' => admin_url( 'admin-ajax.php' ),
'noposts' => __('No older posts found', 'twentyfifteen'),
));
Right after the existing wp_localize_script
. This will load WordPress own admin-ajax.php so that we can use it when we call it in our ajax call.
At the end of the functions.php file I added the function that will load your posts:
function more_post_ajax(){
$ppp = (isset($_POST["ppp"])) ? $_POST["ppp"] : 3;
$page = (isset($_POST['pageNumber'])) ? $_POST['pageNumber'] : 0;
header("Content-Type: text/html");
$args = array(
'suppress_filters' => true,
'post_type' => 'post',
'posts_per_page' => $ppp,
'cat' => 8,
'paged' => $page,
);
$loop = new WP_Query($args);
$out = '';
if ($loop -> have_posts()) : while ($loop -> have_posts()) : $loop -> the_post();
$out .= '<div class="small-12 large-4 columns">
<h1>'.get_the_title().'</h1>
<p>'.get_the_content().'</p>
</div>';
endwhile;
endif;
wp_reset_postdata();
die($out);
}
add_action('wp_ajax_nopriv_more_post_ajax', 'more_post_ajax');
add_action('wp_ajax_more_post_ajax', 'more_post_ajax');
Here I've added paged key in the array, so that the loop can keep track on what page you are when you load your posts.
If you've added your category in the loader, you'd add:
$cat = (isset($_POST['cat'])) ? $_POST['cat'] : '';
And instead of 8, you'd put $cat
. This will be in the $_POST
array, and you'll be able to use it in ajax.
Last part is the ajax itself. In functions.js I put inside the $(document).ready();
enviroment
var ppp = 3; // Post per page
var cat = 8;
var pageNumber = 1;
function load_posts(){
pageNumber++;
var str = '&cat=' + cat + '&pageNumber=' + pageNumber + '&ppp=' + ppp + '&action=more_post_ajax';
$.ajax({
type: "POST",
dataType: "html",
url: ajax_posts.ajaxurl,
data: str,
success: function(data){
var $data = $(data);
if($data.length){
$("#ajax-posts").append($data);
$("#more_posts").attr("disabled",false);
} else{
$("#more_posts").attr("disabled",true);
}
},
error : function(jqXHR, textStatus, errorThrown) {
$loader.html(jqXHR + " :: " + textStatus + " :: " + errorThrown);
}
});
return false;
}
$("#more_posts").on("click",function(){ // When btn is pressed.
$("#more_posts").attr("disabled",true); // Disable the button, temp.
load_posts();
});
Saved it, tested it, and it works :)
Images as proof (don't mind the shoddy styling, it was done quickly). Also post content is gibberish xD
UPDATE
For 'infinite load' instead on click event on the button (just make it invisible, with visibility: hidden;
) you can try with
$(window).on('scroll', function () {
if ($(window).scrollTop() + $(window).height() >= $(document).height() - 100) {
load_posts();
}
});
This should run the load_posts()
function when you're 100px from the bottom of the page. In the case of the tutorial on my site you can add a check to see if the posts are loading (to prevent firing of the ajax twice), and you can fire it when the scroll reaches the top of the footer
$(window).on('scroll', function(){
if($('body').scrollTop()+$(window).height() > $('footer').offset().top){
if(!($loader.hasClass('post_loading_loader') || $loader.hasClass('post_no_more_posts'))){
load_posts();
}
}
});
Now the only drawback in these cases is that you could never scroll to the value of $(document).height() - 100
or $('footer').offset().top
for some reason. If that should happen, just increase the number where the scroll goes to.
You can easily check it by putting console.log
s in your code and see in the inspector what they throw out
$(window).on('scroll', function () {
console.log($(window).scrollTop() + $(window).height());
console.log($(document).height() - 100);
if ($(window).scrollTop() + $(window).height() >= $(document).height() - 100) {
load_posts();
}
});
And just adjust accordingly ;)
Hope this helps :) If you have any questions just ask.
I would use a single Context class inheriting from IdentityDbContext. This way you can have the context be aware of any relations between your classes and the IdentityUser and Roles of the IdentityDbContext. There is very little overhead in the IdentityDbContext, it is basically a regular DbContext with two DbSets. One for the users and one for the roles.
You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.
Have you tried using System.Net.IPAddress just in case?
System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1"); //127.0.0.1 as an example
The docs on Microsoft's site have a complete example which works fine on my machine.
I see that most/all of the above posts search for a button with javascript. This works, as long as you have only one button. I would recommend defining an "onclick" element inside the button. That "onclick" would then call the function causing it to scroll.
If you do it like that, you can use more than one button, as long as the button looks something like this:
<button onclick="scrollTo(document.body, 0, 1250)">To the top</button>
You shouldn't use the keypress
event, but the keyup
or keydown
event because the keypress
event is intended for real (printable) characters. keydown
is handled at a lower level so it will capture all nonprinting keys like delete and enter.
I had this problem with a a number of divs that were inserted in another div with position: absolute
, the inserted divs had no position attribute. When I changed this to position:relative
it worked fine. (was really hard to pinpoint the problem)
In my case the elements where inserted by Angular with ng-repeat
.
The &
means that the function accepts the address (or reference) to a variable, instead of the value of the variable.
For example, note the difference between this:
void af(int& g)
{
g++;
cout<<g;
}
int main()
{
int g = 123;
cout << g;
af(g);
cout << g;
return 0;
}
And this (without the &
):
void af(int g)
{
g++;
cout<<g;
}
int main()
{
int g = 123;
cout << g;
af(g);
cout << g;
return 0;
}
Given your Object:
var foo = { 'bar' : 'baz' }
To get bar
, use:
Object.keys(foo)[0]
To get baz
, use:
foo[Object.keys(foo)[0]]
Assuming a single object
I solved the problem in june of 2017 changing the play-services versions for the latest firebase versions (9.6.1). When I used the latest play-services version (10.2.4) I got that error. The code in the gradle looks like this:
Before
compile 'com.google.android.gms:play-services-maps:10.2.4'
compile 'com.google.android.gms:play-services-places:10.2.4'
compile 'com.google.firebase:firebase-core:9.6.1'
compile 'com.google.firebase:firebase-auth:9.6.1'
After
compile 'com.google.android.gms:play-services-maps:9.6.1'
compile 'com.google.android.gms:play-services-places:9.6.1'
compile 'com.google.firebase:firebase-core:9.6.1'
compile 'com.google.firebase:firebase-auth:9.6.1'
the solution of 'bootstrap modal is not opening' is, put your Jquery CDN first in the head tag (after starting head tag).
I wasted two days in finding this problem.
this
is the current Object instance. Whenever you have a non-static method, it can only be called on an instance of your object.
From access.redhat.com:Sharing_Data_Across_Containers:
Host volume settings are not portable, since they are host-dependent and might not work on any other machine. For this reason, there is no Dockerfile equivalent for mounting host directories to the container. Also, be aware that the host system has no knowledge of container SELinux policy. Therefore, if SELinux policy is enforced, the mounted host directory is not writable to the container, regardless of the rw setting. Currently, you can work around this by assigning the proper SELinux policy type to the host directory":
chcon -Rt svirt_sandbox_file_t host_dir
Where host_dir is a path to the directory on host system that is mounted to the container.
It's seems to be only a workaround, but I tried and it works.
No need to use a macro. Supposing your first string is in A1.
=RIGHT(A1, 4)
Drag this down and you will get your four last characters.
Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()
=RIGHT(TRIMSPACES(A1), 4)
Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:
=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))
There should be a line in your postgresql.conf
file that says:
port = 1486
Change that.
The location of the file can vary depending on your install options. On Debian-based distros it is /etc/postgresql/8.3/main/
On Windows it is C:\Program Files\PostgreSQL\9.3\data
Don't forget to sudo service postgresql restart
for changes to take effect.

Try the following configuration:

log4j.category.debugLogger=TRACE, debugLog
log4j.additivity.debugLogger=false
log4j.category.reportsLogger=DEBUG, reportsLog
log4j.additivity.reportsLogger=false
Then configure the loggers in the Java code accordingly:
static final Logger debugLog = Logger.getLogger("debugLogger");
static final Logger resultLog = Logger.getLogger("reportsLogger");
Do you want output to go to stdout
? If not, change the first line of log4j.properties
to:
log4j.rootLogger=OFF
and get rid of the stdout
lines.
If you format the string and return object like RestApiResponse<String>
, you'll get unwanted characters like escaping etc: \n
, \"
. Solution is to convert your JSON-string into Jackson JsonNode object and return RestApiResponse<JsonNode>
:
ObjectMapper mapper = new ObjectMapper();
JsonNode tree = objectMapper.readTree(jsonString);
RestApiResponse<JsonNode> response = new RestApiResponse<>();
apiResponse.setData(tree);
return response;
Here's a fairly simple way;
SELECT DATEFROMPARTS(YEAR(GETDATE()), 1, 1) AS 'First Day of Current Year';
SELECT DATEFROMPARTS(YEAR(GETDATE()), 12, 31) AS 'End of Current Year';
It's not sexy, but it works.
I have jus this week come across this convention, which seems to be an excellent approach, but I cannot find it referenced anywhere. Is anyone familiar with it? Can you cite a source for it? I have not looked for hours and hours but am hoping someone will recognize this approach.
Example 1: =("012345678905") displays as 012345678905
Example 2: =("1954-12-12") displays as 1954-12-12, not 12/12/1954.
for me, (OSX) the problem was solved doing this:
brew install pkg-config
You can use <CTRL-V><Tab>
in "insert mode". In insert mode, <CTRL-V>
inserts a literal copy of your next character.
If you need to do this often, @Dee`Kej suggested (in the comments) setting Shift+Tab to insert a real tab with this mapping:
:inoremap <S-Tab> <C-V><Tab>
Also, as noted by @feedbackloop, on Windows you may need to press <CTRL-Q>
rather than <CTRL-V>
.
I don't know that regex would handle something like that very well. Try something like this
line = line.Trim();
if(line.StartsWith("for") && line.EndsWith(";")){
//your code here
}
Answering to your question about standard I can cite the C++ Standard §8.3.2/4:
There shall be no references to references, no arrays of references, and no pointers to references.

I'm not familiar with SSRS, but you can get the beginning and end of the previous month in VB.Net using the DateTime
constructor, like this:
Dim prevMonth As DateTime = yourDate.AddMonths(-1)
Dim prevMonthStart As New DateTime(prevMonth.Year, prevMonth.Month, 1)
Dim prevMonthEnd As New DateTime(prevMonth.Year, prevMonth.Month, DateTime.DaysInMonth(prevMonth.Year, prevMonth.Month))
(yourDate
can be any DateTime
object, such as DateTime.Today
or #12/23/2003#
)
See demo here you need to introduce an additiona calss for second div
.overlap{
top: -30px;
position: relative;
left: 30px;
}
You can save your graph as svg for a lossless quality:
import matplotlib.pylab as plt
x = range(10)
plt.figure()
plt.plot(x,x)
plt.savefig("graph.svg")
I made a small library that lets you easily use a throbber without images.
It uses CSS3 but falls back onto JavaScript if the browser doesn't support it.
// First argument is a reference to a container element in which you
// wish to add a throbber to.
// Second argument is the duration in which you want the throbber to
// complete one full circle.
var throbber = throbbage(document.getElementById("container"), 1000);
// Start the throbber.
throbber.play();
// Pause the throbber.
throbber.pause();
Go to Environment Variable and paste the following:
Under System Variable: Step 1: New --> New User Variable 1. Variable name: MAVEN_HOME 2. Variable_value : D:\apache-maven-3.5.2
Step 2: 1. Go to the path --> and paste this - %MAVEN_HOME%\bin
There is already a transparent built into Android: R.color.transparent. http://developer.android.com/reference/android/R.color.html#transparent
But I think you may want to make the background of the image that you are placing into the WebView transparent, for example, with a transparent PNG, rather than the ImageView background. If the actual image is not at all see-through then the ImageView background can't be seen through it.
Version 2.6 and above:
PyCharm (far left menu) -> Preferences... -> Editor (bottom left section) -> General -> Appearance -> Show line numbers checkbox
Version 2.5 and below:
Settings -> Editor -> General -> Appearance -> Show line numbers checkbox
There's no need to manually set the colors. Instead, specify a grayscale colormap...
import numpy as np
import matplotlib.pyplot as plt
# Generate data...
x = np.random.random(10)
y = np.random.random(10)
# Plot...
plt.scatter(x, y, c=y, s=500)
plt.gray()
plt.show()
Or, if you'd prefer a wider range of colormaps, you can also specify the cmap
kwarg to scatter
. To use the reversed version of any of these, just specify the "_r
" version of any of them. E.g. gray_r
instead of gray
. There are several different grayscale colormaps pre-made (e.g. gray
, gist_yarg
, binary
, etc).
import matplotlib.pyplot as plt
import numpy as np
# Generate data...
x = np.random.random(10)
y = np.random.random(10)
plt.scatter(x, y, c=y, s=500, cmap='gray')
plt.show()
There is a difference in performance.
Simply put HS256
is about 1 order of magnitude faster than RS256
for verification but about 2 orders of magnitude faster than RS256
for issuing (signing).
640,251 91,464.3 ops/s
86,123 12,303.3 ops/s (RS256 verify)
7,046 1,006.5 ops/s (RS256 sign)
Don't get hung up on the actual numbers, just think of them with respect of each other.

For Ionic, try this:
ionic cordova plugin add cordova-plugin-androidx
ionic cordova plugin add cordova-plugin-androidx-adapter
The error comes because this app is not using androidX but these plugins solve errors.
I struggled for half a day to get JSCH to work without using the System.in as the input stream to no avail. I tried Ganymed http://www.ganymed.ethz.ch/ssh2/ and had it going in 5 minutes. All the examples seem to be aimed at one usage of the app and none of the examples showed what i needed. Ganymed's example Basic.java Baaaboof Has everything i need.
Since you say you want to access by position once your data is read in, you should know about R's subsetting/ indexing functions.
The easiest is
df[row,column]
#example
df[1:5,] #rows 1:5, all columns
df[,5] #all rows, column 5.
Other methods are here. I personally use the dplyr package for intuitive data manipulation (not by position).
ArrayList<Customer> custArr = new ArrayList<Customer>();
while(youWantToContinue) {
//get a customerName
//get an amount
custArr.add(new Customer(customerName, amount);
}
For this to work... you'll have to fix your constructor...
Assuming your Customer
class has variables called name
and sale
, your constructor should look like this:
public Customer(String customerName, double amount) {
name = customerName;
sale = amount;
}
Change your Store
class to something more like this:
public class Store {
private ArrayList<Customer> custArr;
public new Store() {
custArr = new ArrayList<Customer>();
}
public void addSale(String customerName, double amount) {
custArr.add(new Customer(customerName, amount));
}
public Customer getSaleAtIndex(int index) {
return custArr.get(index);
}
//or if you want the entire ArrayList:
public ArrayList getCustArr() {
return custArr;
}
}
Create a new C# Windows application and call this method from main:
public static void RunBatchFile(string filename)
{
Process process = new Process();
process.StartInfo.FileName = filename;
// suppress output (command window still gets created)
process.StartInfo.Arguments = "> NULL";
process.Start();
process.WaitForExit();
}
Static methods, variables belongs to the whole class, not just an object instance. A static method, variable is associated with the class as a whole rather than with specific instances of a class. Each object will share a common copy of the static methods, variables. There is only one copy per class, no matter how many objects are created from it.
Example:
redis 127.0.0.1:6379> AUTH PASSWORD
(error) ERR Client sent AUTH, but no password is set
redis 127.0.0.1:6379> CONFIG SET requirepass "mypass"
OK
redis 127.0.0.1:6379> AUTH mypass
Ok
As mentioned above
Application.Current.DispatcherUnhandledException will not catch exceptions that are thrown from another thread then the main thread.
That actual depend on how the thread was created
One case that is not handled by Application.Current.DispatcherUnhandledException is System.Windows.Forms.Timer for which Application.ThreadException can be used to handle these if you run Forms on other threads than the main thread you will need to set Application.ThreadException from each such thread
