You can always add the "!" into your float-options. This way, latex tries really hard to place the figure where you want it (I mostly use [h!tb]), stretching the normal rules of type-setting.
I have found another solution:
Use the float-package. This way you can place the figures where you want them to be.
This was happening to me when trying to access Github. The problem is that I was in the habit of doing:
git remote add <xyz> ssh:\\[email protected]......
But, if you are having this error from the question, removing ssh:\\
may resolve the issue. It solved it for me!
Note that you will have to do a git remote remove <xyz>
and re-add the remote url without ssh:\\
.
How to debug any function in console:
Create function where you use pdb.set_trace(), then function you want debug.
>>> import pdb
>>> import my_function
>>> def f():
... pdb.set_trace()
... my_function()
...
Then call created function:
>>> f()
> <stdin>(3)f()
(Pdb) s
--Call--
> <stdin>(1)my_function()
(Pdb)
Happy debugging :)
I used KUE with socketIO like you described. I stored the socketID with the job and could then retreive it in the Job Complete.. KUE is based on redis and has good examples on github
something like this....
jobs.process('YourQueuedJob',10, function(job, done){ doTheJob(job, done); }); function doTheJob(job, done){ var socket = io.sockets.sockets[job.data.socketId]; try { socket.emit('news', { status : 'completed' , task : job.data.task }); } catch(err){ io.sockets.emit('news', { status : 'fail' , task : job.data.task , socketId: job.data.socketId}); } job.complete(); }
I had the same problem. I turned off my WI-FI on my Mac and then turned it on again, which solved the problem. Click Settings > Turn WI-FI Off.
I tested it by going to Safari on my iPhone and entering my host name or IP address. For example:
http://<name>.local
or http://10.0.1.5
cat ~/.ssh/id_rsa.pub
ssh login from Git bash on your computer
ssh -i ~/.ssh/id_rsa [email protected]
Even though an answer has already been accepted, I would like to present what might even be the simplest option:
$ mysqladmin -u bob -p -i 1 processlist
This will print the current queries on your screen every second.
-u
The mysql user you want to execute the command as-p
Prompt for your password (so you don't have to save it in a file or have the command appear in your command history)i
The interval in seconds.--verbose
flag to show the full process list, displaying the entire query for each process. (Thanks, nmat)There is a possible downside: fast queries might not show up if they run between the interval that you set up. IE: My interval is set at one second and if there is a query that takes .02
seconds to run and is ran between intervals, you won't see it.
Use this option preferably when you quickly want to check on running queries without having to set up a listener or anything else.
A solution for me was to create a UILabel
and add it to the UIButton
as a subview. Finally I added a constraint to center it within the button.
UILabel * myTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 75, 75)];
myTextLabel.text = @"Some Text";
myTextLabel.translatesAutoresizingMaskIntoConstraints = false;
[myButton addSubView:myTextLabel];
// Add Constraints
[[myTextLabel centerYAnchor] constraintEqualToAnchor:myButton.centerYAnchor].active = true;
[[myTextLabel centerXAnchor] constraintEqualToAnchor:myButton.centerXAnchor].active = true;
I had Win 8 x86 installed. My Path
variable had entry C:\Program Files\Java\jdk1.6.0_31\bin
and I also had following variables:
JAVA_HOME
: C:\Program Files\Java\jdk1.6.0_31;
JRE_HOME
: C:\Program Files\Java\jre6;
My tomcat is installed at C:\Program Files\Apache Software Foundation\apache-tomcat-7.0.41
And still it did not worked for me.
I tried by replacing Program Files
in those paths with Progra~1
. I also tried by moving JAVA to another folder so that full path to it does not contain any spaces. But nothing worked.
Finally environment variables that worked for me are:
Program Files
i.e. C:\Program Files\Java\jdk1.6.0_31\bin
JAVA_HOME
: C:\Program Files\Java\jdk1.6.0_31
JRE_HOME
So what I did is removed JRE_HOME
and removed semicolon at the end of JAVA_HOME
. I think semicolon should not be an issue, though I removed it. I am giving these settings, since after a lot of googling nothing worked for me and suddenly these seem to work. You can replicate and see if it works for you.
This also worked for Win 7 x64, where
C:\Program Files (x86)\Java\jdk1.7.0_17\bin
JAVA_HOME
is set to C:\Program Files (x86)\Java\jdk1.7.0_17
(without semicoln)Please tell me why this worked, I know removing JRE_HOME
was weird solution, but any guesses what difference it makes?
Using dataset with default values is one way, but you must use query for Available values and for Default Values, if values are hard coded in Available values tab, then you must define default values as expressions. Pictures should explain everything
Create Parameter (if not automaticly created)
Define values - wrong way example
Define values - correct way example
Set default values - you must define all default values reflecting available values to make "Select All" by default, if you won't define all only those defined will be selected by default.
The Result
One picture for Data type: Int
In my case, it was because I was only catching specific types of exceptions:
try
{
get-item -Force -LiteralPath $Path -ErrorAction Stop
#if file exists
if ($Path -like '\\*') {$fileType = 'n'} #Network
elseif ($Path -like '?:\*') {$fileType = 'l'} #Local
else {$fileType = 'u'} #Unknown File Type
}
catch [System.UnauthorizedAccessException] {$fileType = 'i'} #Inaccessible
catch [System.Management.Automation.ItemNotFoundException]{$fileType = 'x'} #Doesn't Exist
Added these to handle additional the exception causing the terminating error, as well as unexpected exceptions
catch [System.Management.Automation.DriveNotFoundException]{$fileType = 'x'} #Doesn't Exist
catch {$fileType='u'} #Unknown
It's best practice only to escape the quotes when you need to - if you can get away without escaping it, then do!
The only times you should need to escape are when trying to put "
inside a string, or '
in a character:
String quotes = "He said \"Hello, World!\"";
char quote = '\'';
The key bindings has been changed with version 1.20:
SHIFT+ALT+0 for Linux.
Presumably the same works for Windows also and CMD+OPT+0 for Mac.
Here how to do it using format()
print "bin_signedDate : ", ''.join(format(x, '08b') for x in bytevector)
It is important the 08b . That means it will be a maximum of 8 leading zeros be appended to complete a byte. If you don't specify this then the format will just have a variable bit length for each converted byte.
If you want to remove part of time from a DateTime
, try using this code:
DateTime dt = new DateTime();
dt = DateTime.Now; //ex: 31/1/2017 6:30:20 PM
TimeSpan remainingTime = new TimeSpan(0, dt.Hour - 5, dt.Minute - 29, dt.Second - 19);
dt=dt.Add(remainingTime);
label1.Text = dt.ToString("HH:mm:ss"); // must be HH not hh
the output : 01:01:01
-- First Truncate temporary table SQL> TRUNCATE TABLE test_temp1; -- Then Drop temporary table SQL> DROP TABLE test_temp1;
My solution is a bit different:
$( 'input[name="your_radio_input_name"]:radio:first' ).click();
Even if the generics problems are fixed in 1.3
the great thing about this method is it works on any class that has an isEmpty()
method! Not just Collections
!
For example it will work on String
as well!
/* Matches any class that has an <code>isEmpty()</code> method
* that returns a <code>boolean</code> */
public class IsEmpty<T> extends TypeSafeMatcher<T>
{
@Factory
public static <T> Matcher<T> empty()
{
return new IsEmpty<T>();
}
@Override
protected boolean matchesSafely(@Nonnull final T item)
{
try { return (boolean) item.getClass().getMethod("isEmpty", (Class<?>[]) null).invoke(item); }
catch (final NoSuchMethodException e) { return false; }
catch (final InvocationTargetException | IllegalAccessException e) { throw new RuntimeException(e); }
}
@Override
public void describeTo(@Nonnull final Description description) { description.appendText("is empty"); }
}
if you need a human-readable timestamp (like rails migration has) ex. "20190527141340"
Time.now.utc.to_formatted_s(:number) # using Rails
Time.now.utc.strftime("%Y%m%d%H%M%S") # using Ruby
echo test > afile.txt
redirects stdout to afile.txt
. This is the same as doing
echo test 1> afile.txt
To redirect stderr, you do:
echo test 2> afile.txt
>&
is the syntax to redirect a stream to another file descriptor - 0 is stdin, 1 is stdout, and 2 is stderr.
You can redirect stdout to stderr by doing:
echo test 1>&2 # or echo test >&2
Or vice versa:
echo test 2>&1
So, in short... 2>
redirects stderr to an (unspecified) file, appending &1
redirects stderr to stdout.
A known issue: https://github.com/angular/angular/issues/4902
Core reason: the .d.ts
file implicitly included by TypeScript varies with the compile target, so one needs to have more ambient declarations when targeting es5
even if things are actually present in the runtimes (e.g. chrome). More on lib.d.ts
for MacOS, make sure you know where the GO install
export GOPATH=/usr/local/go
PATH=$PATH:$GOPATH/bin
You can use BDLocalizedDevicesModels framework to parse device info and get the name.
Then just call UIDevice.currentDevice.productName
in your code.
You can write a custom UICollectionView
layout to achieve this, here is demo image of my implementation:
Here's code repository: KSTCollectionViewPageHorizontalLayout
@iPhoneDev (this maybe help you too)
You can do it by making the following CSS. you can put here the css you need to affect child class in case of hover on the root
.root:hover .child {_x000D_
_x000D_
}
_x000D_
You can download IE Driver (both 32 and 64-bit) from Selenium official site: http://docs.seleniumhq.org/download/
IE Driver is also available in the following site:
Since the name is likely to change in future versions of Android (currently the latest is AppCompatActivity
but it will probably change at some point), I believe a good thing to have is a class Activity
that extends AppCompatActivity
and then all your activities extend from that one. If tomorrow, they change the name to AppCompatActivity2
for instance you will have to change it just in one place.
This is what i use:
html:
<h6><span class="horizontal-line">GET IN</span> TOUCH</h6>
css:
.horizontal-line { border-bottom: 2px solid #FF0000; padding-bottom: 5px; }
$('div[contenteditable]').keydown(function(e) {
// trap the return key being pressed
if (e.keyCode === 13 || e.keyCode === 8)
{
return false;
}
});
In Kotlin you can do as
val videoView = findViewById<VideoView>(R.id.videoView)
// If url is from raw
/* val url = "android.resource://" + packageName
.toString() + "/" + R.raw.video*/
// If url is from network
val url = "http://www.servername.com/projects/projectname/videos/1361439400.mp4"
val video =
Uri.parse(url)
videoView.setVideoURI(video)
videoView.setOnPreparedListener{
videoView.start()
}
You can use gravity with aligning top and bottom.
android:gravity="center_vertical"
android:layout_alignTop="@id/place_category_icon"
android:layout_alignBottom="@id/place_category_icon"
$(this)
and this
aren't the same. The first represents a jQuery object wrapped around your element. The second is just your element. The id
property exists on the element, but not the jQuery object. As such, you have a few options:
Access the property on the element directly:
this.id
Access it from the jQuery object:
$(this).attr("id")
Pull the object out of jQuery:
$(this).get(0).id; // Or $(this)[0].id
Get the id
from the event
object:
When events are raised, for instance a click event, they carry important information and references around with them. In your code above, you have a click event. This event object has a reference to two items: currentTarget
and target
.
Using target
, you can get the id
of the element that raised the event. currentTarget
would simply tell you which element the event is currently bubbling through. These are not always the same.
$("#button").on("click", function(e){ console.log( e.target.id ) });
Of all of these, the best option is to just access it directly from this
itself, unless you're engaged in a series of nested events, then it might be best to use the event
object of each nested event (give them all unique names) to reference elements in higher or lower scopes.
The trick is to create subclasses of ViewHolder and then cast them.
public class GroupViewHolder extends RecyclerView.ViewHolder {
TextView mTitle;
TextView mContent;
public GroupViewHolder(View itemView) {
super (itemView);
// init views...
}
}
public class ImageViewHolder extends RecyclerView.ViewHolder {
ImageView mImage;
public ImageViewHolder(View itemView) {
super (itemView);
// init views...
}
}
private static final int TYPE_IMAGE = 1;
private static final int TYPE_GROUP = 2;
And then, at runtime do something like this:
@Override
public int getItemViewType(int position) {
// here your custom logic to choose the view type
return position == 0 ? TYPE_IMAGE : TYPE_GROUP;
}
@Override
public void onBindViewHolder (ViewHolder viewHolder, int i) {
switch (viewHolder.getItemViewType()) {
case TYPE_IMAGE:
ImageViewHolder imageViewHolder = (ImageViewHolder) viewHolder;
imageViewHolder.mImage.setImageResource(...);
break;
case TYPE_GROUP:
GroupViewHolder groupViewHolder = (GroupViewHolder) viewHolder;
groupViewHolder.mContent.setText(...)
groupViewHolder.mTitle.setText(...);
break;
}
}
Hope it helps.
The easiest and most reliable solution is to try and start a transaction and see it if succeeds. If some code already started a transaction but has not yet issued any DML, then the V$TRANSACTION view won't show anything.
In this example below, I handle the exception to raise a user-defined application error. To defer to an existing exception handler, just do a SET TRANSACTION and then immediately COMMIT to undo it.
DECLARE
transaction_in_progress EXCEPTION;
PRAGMA EXCEPTION_INIT(transaction_in_progress, -1453);
BEGIN
SET TRANSACTION NAME 'CHECK_FOR_TRANSACTION_ALREADY_SET';
COMMIT; -- end transaction
EXCEPTION
WHEN transaction_in_progress THEN
RAISE_APPLICATION_ERROR(-20000,'Transaction is already in progress');
END;

Using Ramda:
import {addIndex, map} from 'ramda';
const list = [ 'h', 'e', 'l', 'l', 'o'];
const mapIndexed = addIndex(map);
mapIndexed((currElement, index) => {
console.log("The current iteration is: " + index);
console.log("The current element is: " + currElement);
console.log("\n");
return 'X';
}, list);
There are 3 different methods depending on what I is my requirement and which version I am using.
Here are the methods..
1) Using Convert
DECLARE @DateTime DATETIME = GETDATE();
--Using Convert
SELECT
CONVERT(NVARCHAR, @DateTime,120) AS 'myDateTime'
,CONVERT(NVARCHAR(10), @DateTime, 120) AS 'myDate'
,RIGHT(CONVERT(NVARCHAR, @DateTime, 120),8) AS 'myTime'
2) Using Cast (SQL Server 2008 and beyond)
SELECT
CAST(@DateTime AS DATETIME2) AS 'myDateTime'
,CAST(@DateTime AS DATETIME2(3)) AS 'myDateTimeWithPrecision'
,CAST(@DateTime AS DATE) AS 'myDate'
,CAST(@DateTime AS TIME) AS 'myTime'
,CAST(@DateTime AS TIME(3)) AS 'myTimeWithPrecision'
3) Using Fixed-length character data type
DECLARE @myDateTime NVARCHAR(20) = CONVERT(NVARCHAR, @DateTime, 120);
DECLARE @myDate NVARCHAR(10) = CONVERT(NVARCHAR, @DateTime, 120);
SELECT
@myDateTime AS 'myDateTime'
,@myDate AS 'myDate'
Changing host_key_checking
to false
for all hosts is a very bad idea.
The only time you want to ignore it, is on "first contact", which these two tasks will accomplish:
- name: Check SSH known_hosts for {{ inventory_hostname }}
local_action: shell ssh-keygen -F {{ inventory_hostname }}
register: checkForKnownHostsEntry
failed_when: false
changed_when: false
ignore_errors: yes
- name: Add {{ inventory_hostname }} to SSH known hosts automatically
when: checkForKnownHostsEntry.rc == 1
changed_when: checkForKnownHostsEntry.rc == 1
set_fact:
ansible_ssh_common_args: '-o StrictHostKeyChecking=no'
So we only turn off host key checking if we don't have the host key in our known_hosts
file.
Check this,
char s='A';
int i = (s<='9')?(s-'0'):(s<='F')?((s-'A')+10):((s-'a')+10);
for only 0,1,2,....,E,F.
This should work for SQL Server:
SELECT * FROM myTable
WHERE month = DATEPART(m, GETDATE()) AND
year = DATEPART(yyyy, GETDATE())
Space characters may only be encoded as "+" in one context: application/x-www-form-urlencoded key-value pairs.
The RFC-1866 (HTML 2.0 specification), paragraph 8.2.1. subparagraph 1. says: "The form field names and values are escaped: space characters are replaced by `+', and then reserved characters are escaped").
Here is an example of such a string in URL where RFC-1866 allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses (in other cases, spaces should be encoded to %20). This way of encoding form data is also given in later HTML specifications, for example, look for relevant paragraphs about application/x-www-form-urlencoded in HTML 4.01 Specification, and so on.
But, because it's hard to always correctly determine the context, it's the best practice to never encode spaces as "+". It's better to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3. Here is a code example that illustrates what should be encoded. It is given in Delphi (pascal) programming language, but it is very easy to understand how it works for any programmer regardless of the language possessed:
(* percent-encode all unreserved characters as defined in RFC-3986, p.2.3 *)
function UrlEncodeRfcA(const S: AnsiString): AnsiString;
const
HexCharArrA: array [0..15] of AnsiChar = '0123456789ABCDEF';
var
I: Integer;
c: AnsiChar;
begin
// percent-encoding, see RFC-3986, p. 2.1
Result := S;
for I := Length(S) downto 1 do
begin
c := S[I];
case c of
'A' .. 'Z', 'a' .. 'z', // alpha
'0' .. '9', // digit
'-', '.', '_', '~':; // rest of unreserved characters as defined in the RFC-3986, p.2.3
else
begin
Result[I] := '%';
Insert('00', Result, I + 1);
Result[I + 1] := HexCharArrA[(Byte(C) shr 4) and $F)];
Result[I + 2] := HexCharArrA[Byte(C) and $F];
end;
end;
end;
end;
function UrlEncodeRfcW(const S: UnicodeString): AnsiString;
begin
Result := UrlEncodeRfcA(Utf8Encode(S));
end;
Use the array module. With it you can store collections of the same type efficiently.
>>> import array
>>> import itertools
>>> a = array_of_signed_ints = array.array("i", itertools.repeat(0, 10))
For more information - e.g. different types, look at the documentation of the array module. For up to 1 million entries this should feel pretty snappy. For 10 million entries my local machine thinks for 1.5 seconds.
The second parameter to array.array is a generator, which constructs the defined sequence as it is read. This way, the array module can consume the zeros one-by-one, but the generator only uses constant memory. This generator does not get bigger (memory-wise) if the sequence gets longer. The array will grow of course, but that should be obvious.
You use it just like a list:
>>> a.append(1)
>>> a.extend([1, 2, 3])
>>> a[-4:]
array('i', [1, 1, 2, 3])
>>> len(a)
14
...or simply convert it to a list:
>>> l = list(a)
>>> len(l)
14
Surprisingly
>>> a = [0] * 10000000
is faster at construction than the array method. Go figure! :)

Now in eclipse Neon this feature is present. No need of any special settings or configuation .On Ctrl+Space the code suggestion is available
This relies on widely available wget
, present almost everywhere, even on Alpine Linux.
wget --server-response --spider --quiet "${url}" 2>&1 | awk 'NR==1{print $2}'
The explanations are as follow :
--quiet
Turn off Wget's output.
Source - wget man pages
--spider
[ ... ] it will not download the pages, just check that they are there. [ ... ]
Source - wget man pages
--server-response
Print the headers sent by HTTP servers and responses sent by FTP servers.
Source - wget man pages
What they don't say about --server-response
is that those headers output are printed to standard error (sterr), thus the need to redirect to stdin.
The output sent to standard input, we can pipe it to awk
to extract the HTTP status code. That code is :
$2
) non-blank group of characters: {$2}
NR==1
And because we want to print it... {print $2}
.
wget --server-response --spider --quiet "${url}" 2>&1 | awk 'NR==1{print $2}'

The blocksize is usually selected to maximize the "occupancy". Search on CUDA Occupancy for more information. In particular, see the CUDA Occupancy Calculator spreadsheet.
If you use another view
make sure to use view.getContext()
instead of this
or getApplicationContext()
First I would recommend you to store your timestamp as a NSNumber
in your Firebase Database, instead of storing it as a String
.
Another thing worth mentioning here, is that if you want to manipulate dates with Swift, you'd better use Date
instead of NSDate
, except if you're interacting with some Obj-C code in your app.
You can of course use both, but the Documentation states:
Date bridges to the NSDate class. You can use these interchangeably in code that interacts with Objective-C APIs.
Now to answer your question, I think the problem here is because of the timezone.
For example if you print(Date())
, as for now, you would get:
2017-09-23 06:59:34 +0000
This is the Greenwich Mean Time (GMT).
So depending on where you are located (or where your users are located) you need to adjust the timezone before (or after, when you try to access the data for example) storing your Date
:
let now = Date()
let formatter = DateFormatter()
formatter.timeZone = TimeZone.current
formatter.dateFormat = "yyyy-MM-dd HH:mm"
let dateString = formatter.string(from: now)
Then you have your properly formatted String
, reflecting the current time at your location, and you're free to do whatever you want with it :) (convert it to a Date
/ NSNumber
, or store it directly as a String
in the database..)
Strict equality operator:-
We can check null by ===
if ( value === null ){
}
Just by using if
if( value ) {
}
will evaluate to true if value is not:
Using BufferedReader:
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
BufferedReader br;
try {
br = new BufferedReader(new FileReader("/fileToRead.txt"));
try {
String x;
while ( (x = br.readLine()) != null ) {
// Printing out each line in the file
System.out.println(x);
}
}
catch (IOException e) {
e.printStackTrace();
}
}
catch (FileNotFoundException e) {
System.out.println(e);
e.printStackTrace();
}
To avoid warnings, you can:
Set-ExecutionPolicy bypass
In addition to registering a ByteArrayHttpMessageConverter
, you may want to use a ResponseEntity
instead of @ResponseBody
. The following code works for me :
@RequestMapping("/photo2")
public ResponseEntity<byte[]> testphoto() throws IOException {
InputStream in = servletContext.getResourceAsStream("/images/no_image.jpg");
final HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.IMAGE_PNG);
return new ResponseEntity<byte[]>(IOUtils.toByteArray(in), headers, HttpStatus.CREATED);
}
Swift 3 This is de correct way for fit all annotations in map.
func zoomMapaFitAnnotations() {
var zoomRect = MKMapRectNull
for annotation in mapview.annotations {
let annotationPoint = MKMapPointForCoordinate(annotation.coordinate)
let pointRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0, 0)
if (MKMapRectIsNull(zoomRect)) {
zoomRect = pointRect
} else {
zoomRect = MKMapRectUnion(zoomRect, pointRect)
}
}
self.mapview.setVisibleMapRect(zoomRect, edgePadding: UIEdgeInsetsMake(50, 50, 50, 50), animated: true)
}
Templates are all about the compiler generating code at compile-time. Virtual functions are all about the run-time system figuring out which function to call at run-time.
Once the run-time system figured out it would need to call a templatized virtual function, compilation is all done and the compiler cannot generate the appropriate instance anymore. Therefore you cannot have virtual member function templates.
However, there are a few powerful and interesting techniques stemming from combining polymorphism and templates, notably so-called type erasure.
I know this is a little old, but for anyone stumbling across this page should know there is a difference between \n and \r\n.
The \r\n gives a CRLF end of line and the \n gives an LF end of line character. There is very little difference to the eye in general.
Create a .txt from the string and then try and open in notepad (normal not notepad++) and you will notice the difference
SHA,PCT,PRACTICE,BNF CODE,BNF NAME,ITEMS,NIC,ACT COST,QUANTITY,PERIOD

If the Line Ends need to be corrected and the file is small enough in size, you can change the line endings in NotePad++ (or paste into word then back into Notepad - although this will make CRLF only).
This may cause some functions that read these files to potenitially no longer function (The example lines given are from GP Prescribing data - England. The file has changed from a CRLF Line end to an LF line end). This stopped an SSIS job from running and failed as couldn't read the LF line endings.
Source of Line Ending Information: https://en.wikipedia.org/wiki/Newline#Representations_in_different_character_encoding_specifications
Hope this helps someone in future :) CRLF = Windows based, LF or CF are from Unix based systems (Linux, MacOS etc.)
You can use a Dictionary to keep track of the keys and values.
For instance...
dictOfStuff = {} ##Make a Dictionary
x = "Buffalo" ##OR it can equal the input of something, up to you.
dictOfStuff[x] = 4 ##Get the dict spot that has the same key ("name") as what X is equal to. In this case "Buffalo". and set it to 4. Or you can set it to what ever you like
print(dictOfStuff[x]) ##print out the value of the spot in the dict that same key ("name") as the dictionary.
A dictionary is very similar to a real life dictionary. You have a word and you have a definition. You can look up the word and get the definition. So in this case, you have the word "Buffalo" and it's definition is 4. It can work with any other word and definition. Just make sure you put them into the dictionary first.
Actually there are 3 places where gradle.properties
can be placed:
GRADLE_USER_HOME
environment variable, which if not set defaults to USER_HOME/.gradlemyProject2
in your case)myProject
)Gradle looks for gradle.properties
in all these places while giving precedence to properties definition based on the order above. So for example, for a property defined in gradle user home directory (#1) and the sub-project (#2) its value will be taken from gradle user home directory (#1).
You can find more details about it in gradle documentation here.
You have to add a manifest to the jar, which tells the java runtime what the main class is. Create a file 'Manifest.mf' with the following content:
Manifest-Version: 1.0
Main-Class: your.programs.MainClass
Change 'your.programs.MainClass' to your actual main class. Now put the file into the Jar-file, in a subfolder named 'META-INF'. You can use any ZIP-utility for that.
Thanks for everyone who answered, and thanks for those who gave me the function-format idea, i'll really study it for future using.
But for this explicit case, the 'special yyyymm field' is not to be considered as a date field, but just as a tag, o whatever would be used for matching the exactly year-month researched value; there is already another date field, with the full timestamp, but if i need all the rows of january 2008, i think that is faster a select like
SELECT [columns] FROM table WHERE yearmonth = '200801'
instead of
SELECT [columns] FROM table WHERE date BETWEEN DATE('2008-01-01') AND DATE('2008-01-31')
I put this in my makefile, right the next line after adb install ...
adb shell monkey -p `cat .identifier` -c android.intent.category.LAUNCHER 1
For this to work there must be a .identifier file with the app's bundle identifier in it, like com.company.ourfirstapp
No need to hunt activity name.

The best answer I have ever seen is How to run 32-bit applications on Ubuntu 64-bit?
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
sudo ./adb
From the line
'key' => env('APP_KEY', 'SomeRandomString'),
APP_KEY
is a global environment variable that is present inside the .env
file.
You can replace the application key if you trigger
php artisan key:generate
command. This will always generate the new key.
The output may be like this:
Application key [Idgz1PE3zO9iNc0E3oeH3CHDPX9MzZe3] set successfully.
Application key [base64:uynE8re8ybt2wabaBjqMwQvLczKlDSQJHCepqxmGffE=] set successfully.
Base64 encoding should be the default in Laravel 5.4
Note that when you first create your Laravel application, key:generate is automatically called.
Hash::make()
will no longer be valid.To kill node server first run this command in your terminal :
top
id
from the previous window: PID number -9 kill
so now you killed your node server try again to run your app.I'm going to add my 2 cents in case someone finds himself in a position like mine. I too was looking for an MVC project type and could not see it. All I saw is a "Web Application Project". So I freaked out and rushed into trying all solutions listed on this page.
But.
IT IS ACTUALLY THERE.
Just go with the "Web application" project and it will give you the MVC option on the next step.
See Soft Tabs and Tab Length under Settings > Editor Settings.
To toggle indentation modes quickly you can use Ctrl-Shift-P and search for Editor: Toggle Soft Tabs.
Setting PYTHONPATH can also help with this problem.
Here is how it can be done on Windows
set PYTHONPATH=.
I've used this creating an IFrame through Javascript and it worked for me:
// IFrame points to the IFrame element, obviously
IFrame.src = 'about: blank';
IFrame.style.backgroundColor = "transparent";
IFrame.frameBorder = "0";
IFrame.allowTransparency="true";
Not sure if it makes any difference, but I set those properties before adding the IFrame to the DOM. After adding it to the DOM, I set its src to the real URL.
Strings in Python are immutable (meaning that their data cannot be modified) so the replace method doesn't modify the string - it returns a new string. You could fix your code as follows:
for i in hello:
j = i.replace(' ','')
k.append(j)
However a better way to achieve your aim is to use a list comprehension. For example the following code removes leading and trailing spaces from every string in the list using strip
:
hello = [x.strip(' ') for x in hello]
What seems to be confusing you is the fact that functions that are declared to be pass-by-reference (using the &
) aren't called using actual addresses, i.e. &a
.
The simple answer is that declaring a function as pass-by-reference:
void foo(int& x);
is all we need. It's then passed by reference automatically.
You now call this function like so:
int y = 5;
foo(y);
and y
will be passed by reference.
You could also do it like this (but why would you? The mantra is: Use references when possible, pointers when needed) :
#include <iostream>
using namespace std;
class CDummy {
public:
int isitme (CDummy* param);
};
int CDummy::isitme (CDummy* param)
{
if (param == this) return true;
else return false;
}
int main () {
CDummy a;
CDummy* b = &a; // assigning address of a to b
if ( b->isitme(&a) ) // Called with &a (address of a) instead of a
cout << "yes, &a is b";
return 0;
}
Output:
yes, &a is b
Your code for setting value for hidden input is correct. Here is the example. Maybe you have some conditions in your if
statements that are not allowing your scripts to execute.
Perhaps:
> data.frame(aname=NA, bname=NA)[numeric(0), ]
[1] aname bname
<0 rows> (or 0-length row.names)
In Gitlab CE 9.0, You can change the default branch from the Settings Tab in a repository's header.
I have used lodash "unset" to make it happen for nested object also.. only this need to write small logic to get path of property key which expected by omit method.

None of these answers worked well for me. This package, pynput, does exactly what I need.
https://pypi.python.org/pypi/pynput
from pynput.keyboard import Key, Listener
def on_press(key):
print('{0} pressed'.format(
key))
def on_release(key):
print('{0} release'.format(
key))
if key == Key.esc:
# Stop listener
return False
# Collect events until released
with Listener(
on_press=on_press,
on_release=on_release) as listener:
listener.join()
Both source and target should be specified. I recommend providing ant defaults, that way you do not need to specify source/target attribute for every javac task:
<property name="ant.build.javac.source" value="1.5"/>
<property name="ant.build.javac.target" value="1.5"/>
See Java cross-compiling notes for more information.
Recovering from Repository Corruption is the official answer.
The really short answer is: find uncorrupted objects and copy them.

I figured out the solutions using selenium 2.0 classes.
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.ie.InternetExplorerDriver;
public class WebTableExample
{
public static void main(String[] args)
{
WebDriver driver = new InternetExplorerDriver();
driver.get("http://localhost/test/test.html");
WebElement table_element = driver.findElement(By.id("testTable"));
List<WebElement> tr_collection=table_element.findElements(By.xpath("id('testTable')/tbody/tr"));
System.out.println("NUMBER OF ROWS IN THIS TABLE = "+tr_collection.size());
int row_num,col_num;
row_num=1;
for(WebElement trElement : tr_collection)
{
List<WebElement> td_collection=trElement.findElements(By.xpath("td"));
System.out.println("NUMBER OF COLUMNS="+td_collection.size());
col_num=1;
for(WebElement tdElement : td_collection)
{
System.out.println("row # "+row_num+", col # "+col_num+ "text="+tdElement.getText());
col_num++;
}
row_num++;
}
}
}
In my case I resolved that problem using such approach:
JAVA_TOOL_OPTIONS = -Dfile.encoding=UTF8
MAVEN_OPTS= -Dfile.encoding=UTF-8

I suspect there are many answers like this on SO but here you go:
if ( typeof pagetype !== 'undefined' && pagetype == 'textpage' ) {
...
}
For SQL statements you can try reverse snowflakes. You can join at sourceforge or the demo site at http://snowflakejoins.com/.
You can use the getters of java.time.LocalDateTime
for that.
LocalDateTime now = LocalDateTime.now();
int year = now.getYear();
int month = now.getMonthValue();
int day = now.getDayOfMonth();
int hour = now.getHour();
int minute = now.getMinute();
int second = now.getSecond();
int millis = now.get(ChronoField.MILLI_OF_SECOND); // Note: no direct getter available.
System.out.printf("%d-%02d-%02d %02d:%02d:%02d.%03d", year, month, day, hour, minute, second, millis);
Or, when you're not on Java 8 yet, make use of java.util.Calendar
.
Calendar now = Calendar.getInstance();
int year = now.get(Calendar.YEAR);
int month = now.get(Calendar.MONTH) + 1; // Note: zero based!
int day = now.get(Calendar.DAY_OF_MONTH);
int hour = now.get(Calendar.HOUR_OF_DAY);
int minute = now.get(Calendar.MINUTE);
int second = now.get(Calendar.SECOND);
int millis = now.get(Calendar.MILLISECOND);
System.out.printf("%d-%02d-%02d %02d:%02d:%02d.%03d", year, month, day, hour, minute, second, millis);
Either way, this prints as of now:
2010-04-16 15:15:17.816
To convert an int
to String
, make use of String#valueOf()
.
If your intent is after all to arrange and display them in a human friendly string format, then better use either Java8's java.time.format.DateTimeFormatter
(tutorial here),
LocalDateTime now = LocalDateTime.now();
String format1 = now.format(DateTimeFormatter.ISO_DATE_TIME);
String format2 = now.atZone(ZoneId.of("GMT")).format(DateTimeFormatter.RFC_1123_DATE_TIME);
String format3 = now.format(DateTimeFormatter.ofPattern("yyyyMMddHHmmss", Locale.ENGLISH));
System.out.println(format1);
System.out.println(format2);
System.out.println(format3);
or when you're not on Java 8 yet, use java.text.SimpleDateFormat
:
Date now = new Date(); // java.util.Date, NOT java.sql.Date or java.sql.Timestamp!
String format1 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS", Locale.ENGLISH).format(now);
String format2 = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss Z", Locale.ENGLISH).format(now);
String format3 = new SimpleDateFormat("yyyyMMddHHmmss", Locale.ENGLISH).format(now);
System.out.println(format1);
System.out.println(format2);
System.out.println(format3);
Either way, this yields:
2010-04-16T15:15:17.816 Fri, 16 Apr 2010 15:15:17 GMT 20100416151517
Couln't find answer above that would both work and be SMALL, and would support nested objects (not arrays), so I wrote my own one :) Works both with strings and ints.
function sortObjectProperties(obj, sortValue){
var keysSorted = Object.keys(obj).sort(function(a,b){return obj[a][sortValue]-obj[b][sortValue]});
var objSorted = {};
for(var i = 0; i < keysSorted.length; i++){
objSorted[keysSorted[i]] = obj[keysSorted[i]];
}
return objSorted;
}
Usage:
/* sample object with unsorder properties, that we want to sort by
their "customValue" property */
var objUnsorted = {
prop1 : {
customValue : 'ZZ'
},
prop2 : {
customValue : 'AA'
}
}
// call the function, passing object and property with it should be sorted out
var objSorted = sortObjectProperties(objUnsorted, 'customValue');
// now console.log(objSorted) will return:
{
prop2 : {
customValue : 'AA'
},
prop1 : {
customValue : 'ZZ'
}
}
You need a split function:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
Create Function [dbo].[udf_Split]
(
@DelimitedList nvarchar(max)
, @Delimiter nvarchar(2) = ','
)
RETURNS TABLE
AS
RETURN
(
With CorrectedList As
(
Select Case When Left(@DelimitedList, Len(@Delimiter)) <> @Delimiter Then @Delimiter Else '' End
+ @DelimitedList
+ Case When Right(@DelimitedList, Len(@Delimiter)) <> @Delimiter Then @Delimiter Else '' End
As List
, Len(@Delimiter) As DelimiterLen
)
, Numbers As
(
Select TOP( Coalesce(DataLength(@DelimitedList)/2,0) ) Row_Number() Over ( Order By c1.object_id ) As Value
From sys.columns As c1
Cross Join sys.columns As c2
)
Select CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen As Position
, Substring (
CL.List
, CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen
, CharIndex(@Delimiter, CL.list, N.Value + 1)
- ( CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen )
) As Value
From CorrectedList As CL
Cross Join Numbers As N
Where N.Value <= DataLength(CL.List) / 2
And Substring(CL.List, N.Value, CL.DelimiterLen) = @Delimiter
)
With your split function, you would then use Cross Apply to get the data:
Select T.Col1, T.Col2
, Substring( Z.Value, 1, Charindex(' = ', Z.Value) - 1 ) As AttributeName
, Substring( Z.Value, Charindex(' = ', Z.Value) + 1, Len(Z.Value) ) As Value
From Table01 As T
Cross Apply dbo.udf_Split( T.Col3, '|' ) As Z
Also, It can be done with LINQ
var str = "Hello@Hello&Hello(Hello)";
var characters = str.Select(c => char.IsLetter(c) ? c : ',')).ToArray();
var output = new string(characters);
Console.WriteLine(output);

I was having a similar problem. PHP was working on my sites configured by virtualmin but not for phpmyadmin. PHPMyAdmin would not execute and the file was being downloaded by the browser. Everything I was reading was saying that libapache2-mod-php5 was not installed but I knew it was... so the thing to do was to purge it and reinstall.
sudo apt-get purge libapache2-mod-php5
sudo apt-get install libapache2-mod-php5
sudo apt-get purge phpmyadmin
sudo apt-get install phpmyadmin
sudo /etc/init.d/apache2 restart
Is your type really arbitrary? If you know it is just going to be a int float or string you could just do
if val.dtype == float and np.isnan(val):
assuming it is wrapped in numpy , it will always have a dtype and only float and complex can be NaN
After Xcode 7, the bitcode option will be enabled by default. If your library was compiled without bitcode, but the bitcode option is enabled in your project settings, you can:
And the Library Build Settings to remove the warnings.

The date function would be defined something like this:
function date($format, $timestamp = null)
{
if ($timestamp === null) {
$timestamp = time();
}
// Format the timestamp according to $format
}
Usually, you would put the default value like this:
function foo($required, $optional = 42)
{
// This function can be passed one or more arguments
}
However, only literals are valid default arguments, which is why I used null
as default argument in the first example, not $timestamp = time()
, and combined it with a null check. Literals include arrays (array()
or []
), booleans, numbers, strings, and null
.
Although the CONVERT thing works, you actually shouldn't use it. You should ask yourself why you are parsing string values in SQL-Server. If this is a one-time job where you are manually fixing some data you won't get that data another time, this is ok, but if any application is using this, you should change something. Best way would be to use the "date" data type. If this is user input, this is even worse. Then you should first do some checking in the client. If you really want to pass string values where SQL-Server expects a date, you can always use ISO format ('YYYYMMDD') and it should convert automatically.

Yes, SQL Server 2012 supports multiple inserts - that feature was introduced in SQL Server 2008.
That makes me wonder if you have Management Studio 2012, but you're really connected to a SQL Server 2005 instance ...
What version of the SQL Server engine do you get from SELECT @@VERSION

If you want to manually count it, the size of a struct is just the size of each of its data members after accounting for alignment. There's no magic overhead bytes for a struct.
For me I had multiple versions of the same library included in /app/libs

Deleting the V3
jar solves the problem.
Try this
$_SERVER['HTTP_CF_CONNECTING_IP'];
instead of
$_SERVER["REMOTE_ADDR"];
str.c_str()
gives you a const char *
, which is an LPCSTR
(Long Pointer to Constant STRing) -- means that it's a pointer to a 0
terminated string of characters. W
means wide string (composed of wchar_t

You can use like this:
import os
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
# Redirect from here, replace your custom site url "www.google.com"
return redirect("https://www.google.com", code=200)
if __name__ == '__main__':
# Bind to PORT if defined, otherwise default to 5000.
port = int(os.environ.get('PORT', 5000))
app.run(host='0.0.0.0', port=port)
You can use : ?+?+K to show keyboard on simulator.
I solved the problem for me by addressing also the worksheet first:
ws.rows(x & ":" & y).Select
without the reference to the worksheet (ws) I got an error.
Your best option will be to create a simple data structure to model what you have. Then you can store these objects in a simple list and sort/retrieve them any way you wish.
For this case, I'd use the following class:
class Fruit:
def __init__(self, name, color, quantity):
self.name = name
self.color = color
self.quantity = quantity
def __str__(self):
return "Name: %s, Color: %s, Quantity: %s" % \
(self.name, self.color, self.quantity)
Then you can simply construct "Fruit" instances and add them to a list, as shown in the following manner:
fruit1 = Fruit("apple", "red", 12)
fruit2 = Fruit("pear", "green", 22)
fruit3 = Fruit("banana", "yellow", 32)
fruits = [fruit3, fruit2, fruit1]
The simple list fruits
will be much easier, less confusing, and better-maintained.
Some examples of use:
All outputs below is the result after running the given code snippet followed by:
for fruit in fruits:
print fruit
Unsorted list:
Displays:
Name: banana, Color: yellow, Quantity: 32
Name: pear, Color: green, Quantity: 22
Name: apple, Color: red, Quantity: 12
Sorted alphabetically by name:
fruits.sort(key=lambda x: x.name.lower())
Displays:
Name: apple, Color: red, Quantity: 12
Name: banana, Color: yellow, Quantity: 32
Name: pear, Color: green, Quantity: 22
Sorted by quantity:
fruits.sort(key=lambda x: x.quantity)
Displays:
Name: apple, Color: red, Quantity: 12
Name: pear, Color: green, Quantity: 22
Name: banana, Color: yellow, Quantity: 32
Where color == red:
red_fruit = filter(lambda f: f.color == "red", fruits)
Displays:
Name: apple, Color: red, Quantity: 12
If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows:
Intent LaunchIntent = getActivity().getPackageManager().getLaunchIntentForPackage(CALC_PACKAGE_NAME);
startActivity(LaunchIntent);
Hope it helps.
Update: AdoptOpenJDK has changed its name to Adoptium, as part of its move to the Eclipse Foundation.
Difference between OpenJDK and AdoptOpenJDK
The first provides source-code, the other provides builds of that source-code.
Adoptium of the Eclipse Foundation, formerly known as AdoptOpenJDK, is only one of several vendors distributing implementations of the Java platform. These include:
See this flowchart of mine to help guide you in picking a vendor for an implementation of the Java platform. Click/tap to zoom.
Another resource: This comparison matrix by Azul Systems is useful, and seems true and fair to my mind.
Here is a list of considerations and motivations to consider in choosing a vendor and implementation.
Some vendors offer you a choice of JIT technologies.

This can also be set in the configuration file matplotlibrc
(as explained in the error message), for instance:
# The default backend; one of GTK GTKAgg GTKCairo GTK3Agg GTK3Cairo
# CocoaAgg MacOSX Qt4Agg Qt5Agg TkAgg WX WXAgg Agg Cairo GDK PS PDF SVG
backend : Agg
That way, the backend does not need to be hardcoded if the code is shared with other people. For more information, check the documentation.
I only check null string with
if ([myString isEqual:[NSNull null]])
Implementing multiple interfaces is very useful and doesn't cause much problems to language implementers nor programmers. So it is allowed. Multiple inheritance while also useful, can cause serious problems to users (dreaded diamond of death). And most things you do with multiple inheritance can be also done by composition or using inner classes. So multiple inheritance is forbidden as bringing more problems than gains.
It is easier to compare dates using the java.util.Calendar
.
Here is what you might do:
Calendar toDate = Calendar.getInstance();
Calendar nowDate = Calendar.getInstance();
toDate.set(<set-year>,<set-month>,<set-day>);
if(!toDate.before(nowDate)) {
//display your report
} else {
// don't display the report
}
You can also install gems in your local environment (without sudo
) with
gem install --user-install <gemname>
I recommend that so you don't mess with your system-level configuration even if it's a single-user computer.
You can check where the gems go by looking at gempaths with gem environment
. In my case it's "~/.gem/ruby/1.8".
If you need some binaries from local installs added to your path, you can add something to your bashrc like:
if which ruby >/dev/null && which gem >/dev/null; then
PATH="$(ruby -r rubygems -e 'puts Gem.user_dir')/bin:$PATH"
fi
You just need to write the first query as a subquery (derived table), inside parentheses, pick an alias for it (t
below) and alias the columns as well.
The DISTINCT
can also be safely removed as the internal GROUP BY
makes it redundant:
SELECT DATE(`date`) AS `date` , COUNT(`player_name`) AS `player_count`
FROM (
SELECT MIN(`date`) AS `date`, `player_name`
FROM `player_playtime`
GROUP BY `player_name`
) AS t
GROUP BY DATE( `date`) DESC LIMIT 60 ;
Since the COUNT
is now obvious that is only counting rows of the derived table, you can replace it with COUNT(*)
and further simplify the query:
SELECT t.date , COUNT(*) AS player_count
FROM (
SELECT DATE(MIN(`date`)) AS date
FROM player_playtime
GROUP BY player_name
) AS t
GROUP BY t.date DESC LIMIT 60 ;
Off hand, setting the http.agent
system property to ""
might do the trick (I don't have the code in front of me).
You might get away with:
System.setProperty("http.agent", "");
but that might require a race between you and initialisation of the URL protocol handler, if it caches the value at startup (actually, I don't think it does).
The property can also be set through JNLP files (available to applets from 6u10) and on the command line:
-Dhttp.agent=
Or for wrapper commands:
-J-Dhttp.agent=
As I wrote in the edits of the op, to edit existing excel documents you must use the xlutils
module (Thanks Oliver)
Here is the proper way to do it:
#xlrd, xlutils and xlwt modules need to be installed.
#Can be done via pip install <module>
from xlrd import open_workbook
from xlutils.copy import copy
rb = open_workbook("names.xls")
wb = copy(rb)
s = wb.get_sheet(0)
s.write(0,0,'A1')
wb.save('names.xls')
This replaces the contents of the cell located at a1 in the first sheet of "names.xls" with the text "a1", and then saves the document.
You can use LINQ's .Select()
to do that. In your case it would go something like:
string Name = yourDbContext
.MyTable
.Where(u => u.UserId == 1)
.Select(u => u.Name)
.SingleOrDefault(); // This is what actually executes the request and return a response
If you are expecting more than one entry in response, you can use .ToList()
instead, to execute the request. Something like this, to get the Name of everyone with age 30:
string[] Names = yourDbContext
.MyTable
.Where(u => u.Age == 30)
.Select(u => u.Name)
.ToList();
According to the documentation on random.uniform
:
Return a random floating point number N such that a <= N <= b for a <= b and b <= N <= a for b < a.
while random.random
:
Return the next random floating point number in the range [0.0, 1.0).
I.e. with random.uniform
you specify a range you draw pseudo-random numbers from, e.g. between 3 and 10. With random.random
you get a number between 0 and 1.
I know the topic is old, but I just fell on it after a google search so... here is another solution:
$array_merged = array_merge($array_going_first, $array_going_second);
This one seems pretty clean to me, it works just fine!
Another approach would be to use a NOT EXISTS
condition in your join condition to test for later purchases:
SELECT *
FROM customer c
LEFT JOIN purchase p ON (
c.id = p.customer_id
AND NOT EXISTS (
SELECT 1 FROM purchase p1
WHERE p1.customer_id = c.id
AND p1.id > p.id
)
)
if you don't want to deactivate or activate the already installed venv just ensure you have set the pythonpath set
set pythonpath=C:\software\venv\include;C:\software\venv\lib;C:\software\venv\scripts;C:\software\venv\tcl;C:\software\venv\Lib\site-packages;
and then execute
"%pythonpath%" %venvpath%Scripts\mytestsite\manage.py runserver "%ipaddress%":8000
Handling CORS requests properly is a tad more involved. Here is a function that will respond more fully (and properly).
/**
* An example CORS-compliant method. It will allow any GET, POST, or OPTIONS requests from any
* origin.
*
* In a production environment, you probably want to be more restrictive, but this gives you
* the general idea of what is involved. For the nitty-gritty low-down, read:
*
* - https://developer.mozilla.org/en/HTTP_access_control
* - https://fetch.spec.whatwg.org/#http-cors-protocol
*
*/
function cors() {
// Allow from any origin
if (isset($_SERVER['HTTP_ORIGIN'])) {
// Decide if the origin in $_SERVER['HTTP_ORIGIN'] is one
// you want to allow, and if so:
header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Max-Age: 86400'); // cache for 1 day
}
// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
// may also be using PUT, PATCH, HEAD etc
header("Access-Control-Allow-Methods: GET, POST, OPTIONS");
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
exit(0);
}
echo "You have CORS!";
}
When a browser wants to execute a cross-site request it first confirms that this is okay with a "pre-flight" request to the URL. By allowing CORS you are telling the browser that responses from this URL can be shared with other domains.
CORS does not protect your server. CORS attempts to protect your users by telling browsers what the restrictions should be on sharing responses with other domains. Normally this kind of sharing is utterly forbidden, so CORS is a way to poke a hole in the browser's normal security policy. These holes should be as small as possible, so always check the HTTP_ORIGIN against some kind of internal list.
There are some dangers here, especially if the data the URL serves up is normally protected. You are effectively allowing browser content that originated on some other server to read (and possibly manipulate) data on your server.
If you are going to use CORS, please read the protocol carefully (it is quite small) and try to understand what you're doing. A reference URL is given in the code sample for that purpose.
It has been observed that the HTTP_ORIGIN header is insecure, and that is true. In fact, all HTTP headers are insecure to varying meanings of the term. Unless a header includes a verifiable signature/hmac, or the whole conversation is authenticated via TLS, headers are just "something the browser has told me".
In this case, the browser is saying "an object from domain X wants to get a response from this URL. Is that okay?" The point of CORS is to be able to answer, "yes I'll allow that".
I just use a query like Martin Smith mentioned, just little shorter:
SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'YourTableName'
The following works for me when disabling Findbugs in a child POM:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>findbugs-maven-plugin</artifactId>
<executions>
<execution>
<id>ID_AS_IN_PARENT</id> <!-- id is necessary sometimes -->
<phase>none</phase>
</execution>
</executions>
</plugin>
Note: the full definition of the Findbugs plugin is in our parent/super POM, so it'll inherit the version and so-on.
In Maven 3, you'll need to use:
<configuration>
<skip>true</skip>
</configuration>
for the plugin.
As indicated by the other answers, the error is to due to k = list[0:j]
, where your key is converted to a list. One thing you could try is reworking your code to take advantage of the split
function:
# Using with ensures that the file is properly closed when you're done
with open('filename.txt', 'rb') as f:
d = {}
# Here we use readlines() to split the file into a list where each element is a line
for line in f.readlines():
# Now we split the file on `x`, since the part before the x will be
# the key and the part after the value
line = line.split('x')
# Take the line parts and strip out the spaces, assigning them to the variables
# Once you get a bit more comfortable, this works as well:
# key, value = [x.strip() for x in line]
key = line[0].strip()
value = line[1].strip()
# Now we check if the dictionary contains the key; if so, append the new value,
# and if not, make a new list that contains the current value
# (For future reference, this is a great place for a defaultdict :)
if key in d:
d[key].append(value)
else:
d[key] = [value]
print d
# {'AAA': ['111', '112'], 'AAC': ['123'], 'AAB': ['111']}
Note that if you are using Python 3.x, you'll have to make a minor adjustment to get it work properly. If you open the file with rb
, you'll need to use line = line.split(b'x')
(which makes sure you are splitting the byte with the proper type of string). You can also open the file using with open('filename.txt', 'rU') as f:
(or even with open('filename.txt', 'r') as f:
) and it should work fine.
Yes, that's the correct way to do it. If you're looking to give yourself a "Clean" (or, as I'd prefer to call it, "Empty" function), you can create an extension method.
public static void Empty(this System.IO.DirectoryInfo directory)
{
foreach(System.IO.FileInfo file in directory.GetFiles()) file.Delete();
foreach(System.IO.DirectoryInfo subDirectory in directory.GetDirectories()) subDirectory.Delete(true);
}
This will then allow you to do something like..
System.IO.DirectoryInfo directory = new System.IO.DirectoryInfo(@"C:\...");
directory.Empty();
<input name="date" type="text" (focus)="focusFunction()" (focusout)="focusOutFunction()">

if you can write a batch file that does not need to be interactive, try running that batch file as a service, to do what needs to be done.
If your DIV tag is immediately followed by the IMG tag, you can also use:
$(this).next();
You can refer to event modifiers in vuejs to prevent form submission on enter
key.
It is a very common need to call
event.preventDefault()
orevent.stopPropagation()
inside event handlers.Although we can do this easily inside methods, it would be better if the methods can be purely about data logic rather than having to deal with DOM event details.
To address this problem, Vue provides event modifiers for
v-on
. Recall that modifiers are directive postfixes denoted by a dot.
<form v-on:submit.prevent="<method>">
...
</form>
As the documentation states, this is syntactical sugar for e.preventDefault()
and will stop the unwanted form submission on press of enter key.
Here is a working fiddle.

Here's an example of how you could implement a list view:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//We have our list view
final ListView dynamic = findViewById(R.id.dynamic);
//Create an array of elements
final ArrayList<String> classes = new ArrayList<>();
classes.add("Data Structures");
classes.add("Assembly Language");
classes.add("Calculus 3");
classes.add("Switching Systems");
classes.add("Analysis Tools");
//Create adapter for ArrayList
final ArrayAdapter<String> adapter = new ArrayAdapter<>(this,android.R.layout.simple_list_item_1, classes);
//Insert Adapter into List
dynamic.setAdapter(adapter);
//set click functionality for each list item
dynamic.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.i("User clicked ", classes.get(position));
}
});
}
Additional to the jQuery thing treated in the other answers there is another meaning in JavaScript - as prefix for the RegExp properties representing matches, for example:
"test".match( /t(e)st/ );
alert( RegExp.$1 );
will alert "e"
But also here it's not "magic" but simply part of the properties name
You're looking for basename
.
The example from the PHP manual:
<?php
$path = "/home/httpd/html/index.php";
$file = basename($path); // $file is set to "index.php"
$file = basename($path, ".php"); // $file is set to "index"
?>
str.lower()
converts all cased characters to lowercase.
Declare an output cursor variable to the inner sp :
@c CURSOR VARYING OUTPUT
Then declare a cursor c to the select you want to return. Then open the cursor. Then set the reference:
DECLARE c CURSOR LOCAL FAST_FORWARD READ_ONLY FOR
SELECT ...
OPEN c
SET @c = c
DO NOT close or reallocate.
Now call the inner sp from the outer one supplying a cursor parameter like:
exec sp_abc a,b,c,, @cOUT OUTPUT
Once the inner sp executes, your @cOUT
is ready to fetch. Loop and then close and deallocate.
As for how to represent a single apostrophe as a string in Python, you can simply surround it with double quotes ("'"
) or you can escape it inside single quotes ('\''
).
To remove apostrophes from a string, a simple approach is to just replace the apostrophe character with an empty string:
>>> "didn't".replace("'", "")
'didnt'
Swift 4 - GET request
var request = URLRequest(url: URL(string: "http://example.com/api/v1/example")!)

do {
let jsonDecoder = JSONDecoder()
let responseModel = try jsonDecoder.decode(CustomDtoClass.self, from: data!)
print(responseModel)
} catch {

Don't forget to configure App Transport Security Settings to add your domain to the exceptions and allow insecure http requests if you're hitting endpoints without using HTTPS.
You can use a tool like http://www.json4swift.com/ to autogenerate your Codeable Mappings from your JSON responses.
Here's how I usually do it. For example, to calculate 1717 mod 2
:
1717 / 2
. The answer is 858.52
) to get 1716
1717
) minus the number you got from the previous step (1716
) -- 1717-1716=1
.So 1717 mod 2
is 1
.
To sum this up all you have to do is multiply the numbers before the decimal point with the mod then subtract it from the original number.
def test():
r1 = 1
r2 = 2
r3 = 3
return r1, r2, r3
x,y,z = test()
print x
print y
print z
> test.py

One way to look at it is that the visitor pattern is a way of letting your clients add additional methods to all of your classes in a particular class hierarchy.
It is useful when you have a fairly stable class hierarchy, but you have changing requirements of what needs to be done with that hierarchy.
The classic example is for compilers and the like. An Abstract Syntax Tree (AST) can accurately define the structure of the programming language, but the operations you might want to do on the AST will change as your project advances: code-generators, pretty-printers, debuggers, complexity metrics analysis.
Without the Visitor Pattern, every time a developer wanted to add a new feature, they would need to add that method to every feature in the base class. This is particularly hard when the base classes appear in a separate library, or are produced by a separate team.
(I have heard it argued that the Visitor pattern is in conflict with good OO practices, because it moves the operations of the data away from the data. The Visitor pattern is useful in precisely the situation that the normal OO practices fail.)
I not expert in MySQL but you probably should look on triggers e.g. BEFORE INSERT. In the trigger you can run select query on your original table and if it found something just update the row 'logins' instead of inserting new values. But all this depends on version of MySQL you running.
None of the solutions worked for me, so I had to use a WebClient instead of a HttpWebRequest and the issue was no more.
I needed to use a CookieContainer, so I used the solution posted by Pavel Savara in this thread - Using CookieContainer with WebClient class
just remove "protected" from this line:
private readonly CookieContainer container = new CookieContainer();
I used the following code to check if the string contained any of the items in the string array:
foreach (string s in stringArray)
{
if (s != "")
{
if (stringToCheck.Contains(s))
{
Text = "matched";
}
}
}
The best solution I've come across is to create [time display="llll" datetime="UTC TIME" /] Tags, and use javascript (jquery) to parse and display it relative to the user's time.
http://momentjs.com/ Moment.js
will display the time nicely.
you dont need those quotes
<td style="padding-left: 5px;padding-bottom:3px; font-size: 35px;"> <b>Datum:</b><br/>

[ ].has(obj)
assuming .indexOf()
is implemented
Object.defineProperty( Array.prototype,'has',
{
value:function(o, flag){
if (flag === undefined) {
return this.indexOf(o) !== -1;
} else { // only for raw js object
for(var v in this) {
if( JSON.stringify(this[v]) === JSON.stringify(o)) return true;
}
return false;
},
// writable:false,
// enumerable:false
})
!!! do not make Array.prototype.has=function(){...
because you'll add an enumerable element in every array and js is broken.
//use like
[22 ,'a', {prop:'x'}].has(12) // false
["a","b"].has("a") // true
[1,{a:1}].has({a:1},1) // true
[1,{a:1}].has({a:1}) // false
the use of 2nd arg (flag) forces comparation by value instead of reference
comparing raw objects
[o1].has(o2,true) // true if every level value is same
Use:
import color
class Color(color.Color):
...
If this were Python 2.x, you would also want to derive color.Color
from object
, to make it a new-style class:
class Color(object):
...
This is not necessary in Python 3.x.
I had an issue uploading images to my React JS project. I was trying to use the file-loader to load the images; I was also using Babel-loader in my react.
I used the following settings in the webpack:
{test: /\.(jpe?g|png|gif|svg)$/i, loader: "file-loader?name=app/images/[name].[ext]"},
This helped load my images, but the images loaded were kind of corrupted. Then after some research I came to know that file-loader has a bug of corrupting the images when babel-loader is installed.
Hence, to work around the issue I tried to use URL-loader which worked perfectly for me.
I updated my webpack with the following settings
{test: /\.(jpe?g|png|gif|svg)$/i, loader: "url-loader?name=app/images/[name].[ext]"},
I then used the following command to import the images
import img from 'app/images/GM_logo_2.jpg'
<div className="large-8 columns">
<img style={{ width: 300, height: 150 }} src={img} />

As geofflane mentions in his answer, Java 7 now support named groups.
tchrist points out in the comment that the support is limited.
He details the limitations in his great answer "Java Regex Helper"
Java 7 regex named group support was presented back in September 2010 in Oracle's blog.
In the official release of Java 7, the constructs to support the named capturing group are:
(?<name>capturing text)
to define a named group "name"\k<name>
to backreference a named group "name"${name}
to reference to captured group in Matcher's replacement stringMatcher.group(String name)
to return the captured input subsequence by the given "named group".
Other alternatives for pre-Java 7 were:
(Original answer: Jan 2009, with the next two links now broken)
You can not refer to named group, unless you code your own version of Regex...
That is precisely what Gorbush2 did in this thread.
(limited implementation, as pointed out again by tchrist, as it looks only for ASCII identifiers. tchrist details the limitation as:
only being able to have one named group per same name (which you don’t always have control over!) and not being able to use them for in-regex recursion.
Note: You can find true regex recursion examples in Perl and PCRE regexes, as mentioned in Regexp Power, PCRE specs and Matching Strings with Balanced Parentheses slide)
Example:
String:
"TEST 123"
RegExp:
"(?<login>\\w+) (?<id>\\d+)"
Access
matcher.group(1) ==> TEST
matcher.group("login") ==> TEST
matcher.name(1) ==> login
Replace
matcher.replaceAll("aaaaa_$1_sssss_$2____") ==> aaaaa_TEST_sssss_123____
matcher.replaceAll("aaaaa_${login}_sssss_${id}____") ==> aaaaa_TEST_sssss_123____
(extract from the implementation)
public final class Pattern
implements java.io.Serializable
{
[...]
/**
* Parses a group and returns the head node of a set of nodes that process
* the group. Sometimes a double return system is used where the tail is
* returned in root.
*/
private Node group0() {
boolean capturingGroup = false;
Node head = null;
Node tail = null;
int save = flags;
root = null;
int ch = next();
if (ch == '?') {
ch = skip();
switch (ch) {
case '<': // (?<xxx) look behind or group name
ch = read();
int start = cursor;
[...]
// test forGroupName
int startChar = ch;
while(ASCII.isWord(ch) && ch != '>') ch=read();
if(ch == '>'){
// valid group name
int len = cursor-start;
int[] newtemp = new int[2*(len) + 2];
//System.arraycopy(temp, start, newtemp, 0, len);
StringBuilder name = new StringBuilder();
for(int i = start; i< cursor; i++){
name.append((char)temp[i-1]);
}
// create Named group
head = createGroup(false);
((GroupTail)root).name = name.toString();
capturingGroup = true;
tail = root;
head.next = expr(tail);
break;
}
Yep. Had this same problem too. Here's the command I ran and it worked perfectly:
convert transparent-img1.png transparent-img2.png transparent-img3.png -channel Alpha favicon.ico
Modifying Aleksandar's answer to make it as jquery plugin and accepts maxwidth and maxheight as arguments, suggested by Nathan.
$.fn.resize = function(maxWidth,maxHeight) {
return this.each(function() {
var ratio = 0;
var width = $(this).width();
var height = $(this).height();
if(width > maxWidth){
ratio = maxWidth / width;
$(this).css("width", maxWidth);
$(this).css("height", height * ratio);
height = height * ratio;
}
var width = $(this).width();
var height = $(this).height();
if(height > maxHeight){
ratio = maxHeight / height;
$(this).css("height", maxHeight);
$(this).css("width", width * ratio);
width = width * ratio;
}
});
};
Used as $('.imgClass').resize(300,50);
If using a class-based view:
#
# in settings.py
#
YOUR_CUSTOM_SETTING = 'some value'
#
# in views.py
#
from django.conf import settings #for getting settings vars
class YourView(DetailView): #assuming DetailView; whatever though
# ...
def get_context_data(self, **kwargs):
context = super(YourView, self).get_context_data(**kwargs)
context['YOUR_CUSTOM_SETTING'] = settings.YOUR_CUSTOM_SETTING
return context
#
# in your_template.html, reference the setting like any other context variable
#
{{ YOUR_CUSTOM_SETTING }}
It seems that this is the correct way window.location.assign("http://www.mozilla.org");
If you're downloading text then I'd recommend using the WebClient and get a streamreader to the text:
WebClient web = new WebClient();
System.IO.Stream stream = web.OpenRead("http://www.yoursite.com/resource.txt");
using (System.IO.StreamReader reader = new System.IO.StreamReader(stream))
{
String text = reader.ReadToEnd();
}
If this is taking a long time then it is probably a network issue or a problem on the web server. Try opening the resource in a browser and see how long that takes. If the webpage is very large, you may want to look at streaming it in chunks rather than reading all the way to the end as in that example. Look at http://msdn.microsoft.com/en-us/library/system.io.stream.read.aspx to see how to read from a stream.
$('#submenu li').hover(function(){
$('#carousel').css('backgroundPosition', newValue);
});
.card-img-top {
width: 100%;
height: 30vh;
object-fit: contain;
}
Contain will help in getting Complete Image displayed inside Card.
Adjust height "30vh" according to your need!
You should use the sumif function in Excel:
=SUMIF(A5:C10;"Text_to_find";C5:C10)
This function takes a range like this square A5:C10 then you have some text to find this text can be in A or B then it will add the number from the C-row.
You can use this:
yylval.sval=strdup("VHDL + Volcal trance...");
Where yylval is char*. strdup from does the job.
Original answer 2010:
If all of those directories are separate git repo, you should reference them as submodules.
That means your "origin" would be that remote repo 'plugins
' which only contains references to subrepos 'cms
', 'admin
', 'chart
'.
A git pull
followed by a git submodule update
would achieve what your are looking for.
Update January 2016:
With Git 2.8 (Q1 2016), you will be able to fetch submodules in parallel (!) with git fetch --recurse-submodules -j2
.
See "How to speed up / parallelize downloads of git submodules using git clone --recursive?"
Out-File
defaults to unicode encoding which is why you are seeing the behavior you are. Use -Encoding Ascii
to change this behavior. In your case
Out-File -Encoding Ascii -append textfile.txt.
Add-Content
uses Ascii and also appends by default.
"This is a test" | Add-Content textfile.txt.
As for the lack of newline: You did not send a newline so it will not write one to file.
I think it is good to categorize relations like this
When to use eager loading
When to use lazy loading
Note: like Transcendent said there may be disposal problem with lazy loading.
A good reason, which you have sort of touched on, is that once the CSRF cookie has been received, it is then available for use throughout the application in client script for use in both regular forms and AJAX POSTs. This will make sense in a JavaScript heavy application such as one employed by AngularJS (using AngularJS doesn't require that the application will be a single page app, so it would be useful where state needs to flow between different page requests where the CSRF value cannot normally persist in the browser).
Consider the following scenarios and processes in a typical application for some pros and cons of each approach you describe. These are based on the Synchronizer Token Pattern.
Advantages:

So the cookie approach is fairly dynamic offering an easy way to retrieve the cookie value (any HTTP request) and to use it (JS can add the value to any form automatically and it can be employed in AJAX requests either as a header or as a form value). Once the CSRF token has been received for the session, there is no need to regenerate it as an attacker employing a CSRF exploit has no method of retrieving this token. If a malicious user tries to read the user's CSRF token in any of the above methods then this will be prevented by the Same Origin Policy. If a malicious user tries to retrieve the CSRF token server side (e.g. via curl
) then this token will not be associated to the same user account as the victim's auth session cookie will be missing from the request (it would be the attacker's - therefore it won't be associated server side with the victim's session).
As well as the Synchronizer Token Pattern there is also the Double Submit Cookie CSRF prevention method, which of course uses cookies to store a type of CSRF token. This is easier to implement as it does not require any server side state for the CSRF token. The CSRF token in fact could be the standard authentication cookie when using this method, and this value is submitted via cookies as usual with the request, but the value is also repeated in either a hidden field or header, of which an attacker cannot replicate as they cannot read the value in the first place. It would be recommended to choose another cookie however, other than the authentication cookie so that the authentication cookie can be secured by being marked HttpOnly. So this is another common reason why you'd find CSRF prevention using a cookie based method.

Ck-editor documentation is not clear after doing alot of R&D for custom file upload finally i have found this solution. It work for me and i hope it will helpful to others as well.

Below is code that specifies fields from a named range for insertion into MS Access. The nice thing about this code is that you can name your fields in Excel whatever the hell you want (If you use * then the fields have to match exactly between Excel and Access) as you can see I have named an Excel column "Haha" even though the Access column is called "dte".
Sub test()
dbWb = Application.ActiveWorkbook.FullName
dsh = "[" & Application.ActiveSheet.Name & "$]" & "Data2" 'Data2 is a named range
sdbpath = "C:\Users\myname\Desktop\Database2.mdb"
sCommand = "INSERT INTO [main] ([dte], [test1], [values], [values2]) SELECT [haha],[test1],[values],[values2] FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh
Dim dbCon As New ADODB.Connection
Dim dbCommand As New ADODB.Command
dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database Password=;"
dbCommand.ActiveConnection = dbCon
dbCommand.CommandText = sCommand
dbCommand.Execute
dbCon.Close
End Sub
Apply this if you use laravel.
Laravel has a not_regex where field under validation must not match the given regular expression; uses the PHP preg_match

$twoDecNum = sprintf('%0.2f', round($number, 2));
The rounding correctly rounds the number and the sprintf forces it to 2 decimal places if it happens to to be only 1 decimal place after rounding.
Both of these are primary from the old printing days.
Carriage return is from the days of the teletype printers/old typewriters, where literally the carriage would return to the next line, and push the paper up. This is what we now call \r
.
Line feed LF
signals the end of the line, it signals that the line has ended - but doesn't move the cursor to the next line. In other words, it doesn't "return" the cursor/printer head to the next line.
For more sundry details, the mighty wikipedia to the rescue.
It''s not clear to me what you want.
If you want a CSS property to render the alt attribute value, then perhaps you're looking for the CSS attribute function for example:
IMG:before { content: attr(alt) }
If you want to put the alt attribute on a background image, then ... that's odd because the alt attribute is an HTML attribute whereas the background image is a CSS property. If you want to use the HTML alt attribute then I think you'd need a corresponding HTML element to put it in.
Why do you "need to use alt tags on background images": is this for a semantic reason or for some visual-effect reason (and if so, then what effect or what reason)?
You didn't say what version you were using, but in SQL 2005 and above, you can use a common table expression with the OVER Clause. It goes a little something like this:
WITH cte AS (
SELECT[foo], [bar],
row_number() OVER(PARTITION BY foo, bar ORDER BY baz) AS [rn]
FROM TABLE
)
DELETE cte WHERE [rn] > 1
Play around with it and see what you get.
(Edit: In an attempt to be helpful, someone edited the ORDER BY
clause within the CTE. To be clear, you can order by anything you want here, it needn't be one of the columns returned by the cte. In fact, a common use-case here is that "foo, bar" are the group identifier and "baz" is some sort of time stamp. In order to keep the latest, you'd do ORDER BY baz desc
)
It seems to me that simply: ls -lt mydirectory
does the job...
Show all deleted files in some_branch
git diff origin/master...origin/some_branch --name-status | grep ^D
or
git diff origin/master...origin/some_branch --name-status --diff-filter=D
You will need to dynamically insert a script tag into the page that references the data. Using JSONP, you can execute some callback function when the script has loaded.
The wikipedia page on JSONP has a concise example; the script tag:
<script type="text/javascript" src="http://domain1.com/getjson?jsonp=parseResponse">
</script>
would return the JSON data wrapped in a call to parseResponse
:
parseResponse({"Name": "Cheeso", "Rank": 7})
(depending on the configuration of the getjson
script on domain1.com)
The code to insert the tag dynamically would be something like:
var s = document.createElement("script");
s.src = "http://domain1.com/getjson?jsonp=parseResponse";
s.type = "text/javascript";
document.appendChild(s);
I looked into this a bit more and the actual problem seems to be with assigning initial
to page width
under the print
media rule. It seems like in Chrome width: initial
on the .page
element results in scaling of the page content if no specific length value is defined for width
on any of the parent elements (width: initial
in this case resolves to width: auto
... but actually any value smaller than the size defined under the @page
rule causes the same issue).
So not only the content is now too long for the page (by about 2cm
), but also the page padding will be slightly more than the initial 2cm
and so on (it seems to render the contents under width: auto
to the width of ~196mm
and then scale the whole content up to the width of 210mm
~ but strangely exactly the same scaling factor is applied to contents with any width smaller than 210mm
).
To fix this problem you can simply in the print
media rule assign the A4 paper width and hight to html, body
or directly to .page
and in this case avoid the initial
keyword.
@page {
size: A4;
margin: 0;
}
@media print {
html, body {
width: 210mm;
height: 297mm;
}
/* ... the rest of the rules ... */
}
This seems to keep everything else the way it is in your original CSS and fix the problem in Chrome (tested in different versions of Chrome under Windows, OS X and Ubuntu).
If you are working with anaconda-project, you can query the PROJECT_ROOT from the environment variable --> os.getenv('PROJECT_ROOT'). This works only if the script is executed via anaconda-project run .
If you do not want your script run by anaconda-project, you can query the absolute path of the executable binary of the Python interpreter you are using and extract the path string up to the envs directory exclusiv. For example: The python interpreter of my conda env is located at:
/home/user/project_root/envs/default/bin/python
# You can first retrieve the env variable PROJECT_DIR.
# If not set, get the python interpreter location and strip off the string till envs inclusiv...
if os.getenv('PROJECT_DIR'):
PROJECT_DIR = os.getenv('PROJECT_DIR')
else:
PYTHON_PATH = sys.executable
path_rem = os.path.join('envs', 'default', 'bin', 'python')
PROJECT_DIR = py_path.split(path_rem)[0]
This works only with conda-project with fixed project structure of a anaconda-project
#include <iostream>
#include <string>
#include <vector>
#include <boost/assign/list_of.hpp>

std::copy(
v.begin(),
v.end(),

If you only want to return a blank when B2 is blank you can use an additional IF function for that scenario specifically, i.e.
=IF(B2="","",VLOOKUP(B2,Index!A1:B12,2,FALSE))
or to return a blank with any error from the VLOOKUP (e.g. including if B2 is populated but that value isn't found by the VLOOKUP) you can use IFERROR function if you have Excel 2007 or later, i.e.
=IFERROR(VLOOKUP(B2,Index!A1:B12,2,FALSE),"")
in earlier versions you need to repeat the VLOOKUP, e.g.
=IF(ISNA(VLOOKUP(B2,Index!A1:B12,2,FALSE)),"",VLOOKUP(B2,Index!A1:B12,2,FALSE))
Most likely the TinyMce editor is adding its own formatting to the post. You'll need to see how you can escape TinyMce's editing abilities. The code works fine for me. Is it a wordpress blog?

You can introduce another variable. It doesnt consolidate both checks, but it at least avoids having to put the body in twice:
do_it =
ifeq ($(GCC_MINOR), 4)
do_it = yes
endif
ifeq ($(GCC_MINOR), 5)
do_it = yes
endif
ifdef do_it
CFLAGS += -fno-strict-overflow
endif
I presume you are wanting to check if the array contains a certain value, yes? If so, use the contains
method.

Check the modulus of each integer from 2 up to the root of the number you're checking.
If modulus equals zero then it's not prime.
pseudo code:
bool IsPrime(int target)
{
for (i = 2; i <= root(target); i++)
{
if ((target mod i) == 0)
{
return false;
}
}
return true;
}
You can use the csv
module to parse tab seperated value files easily.
import csv
with open("tab-separated-values") as tsv:
for line in csv.reader(tsv, dialect="excel-tab"): #You can also use delimiter="\t" rather than giving a dialect.
...
Where line
is a list of the values on the current row for each iteration.
Edit: As suggested below, if you want to read by column, and not by row, then the best thing to do is use the zip()
builtin:
with open("tab-separated-values") as tsv:
for column in zip(*[line for line in csv.reader(tsv, dialect="excel-tab")]):
...
int *array = new int[n];
It declares a pointer to a dynamic array of type int
and size n
.
A little more detailed answer: new
allocates memory of size equal to sizeof(int) * n
bytes and return the memory which is stored by the variable array
. Also, since the memory is dynamically allocated using new
, you've to deallocate it manually by writing (when you don't need anymore, of course):
delete []array;
Otherwise, your program will leak memory of at least sizeof(int) * n
bytes (possibly more, depending on the allocation strategy used by the implementation).
You can use readstream and pipe to read the file line by line without read all the file into memory one time.
var fs = require('fs'),
es = require('event-stream'),
os = require('os');
var s = fs.createReadStream(path)
.pipe(es.split())
.pipe(es.mapSync(function(line) {
//pause the readstream
s.pause();
console.log("line:", line);
s.resume();
})
.on('error', function(err) {
console.log('Error:', err);
})
.on('end', function() {
console.log('Finish reading.');
})
);
First you create the EditText in the xml file and assign an id, eg con_pag_etPesquisa. After that, we will create two lists, where one is the list view and the other to receive the same content but will remain as a backup. Before moving objects to lists first initializes Them the below:
//Declaring
public EditText etPesquisa;
public ContasPagarAdapter adapterNormal;
public List<ContasPagar> lstBkp;
public List<ContasPagar> lstCp;
//Within the onCreate method, type the following:
etPesquisa = (EditText) findViewById(R.id.con_pag_etPesquisa);
etPesquisa.addTextChangedListener(new TextWatcher(){
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3){
filter(String.valueOf(cs));
}
@Override
public void beforeTextChanged(CharSequence cs, int arg1, int arg2, int arg3){
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable e){
}
});
//Before moving objects to lists first initializes them as below:
lstCp = new ArrayList<ContasPagar>();
lstBkp = new ArrayList<ContasPagar>();
//When you add objects to the main list, repeat the procedure also for bkp list, as follows:
lstCp.add(cp);
lstBkp.add(cp);
//Now initializes the adapter and let the listener, as follows:
adapterNormal = new ContasPagarAdapter(ContasPagarActivity.this, lstCp);
lvContasPagar.setAdapter(adapterNormal);
lvContasPagar.setOnItemClickListener(verificaClickItemContasPagar(lstCp));
//Now create the methods inside actito filter the text entered by the user, as follows:
public void filter(String charText){
charText = charText.toLowerCase();
lstCp.clear();
if (charText.length() == 0){
lstCp.addAll(lstBkp);
appendAddItem(lstBkp);
}
else {
for (int i = 0; i < lstBkp.size(); i++){
if((lstBkp.get(i).getNome_lancamento() + " - " + String.valueOf(lstBkp.get(i).getCodigo())).toLowerCase().contains(charText)){
lstCp.add(lstBkp.get(i));
}
}
appendAddItem(lstCp);
}
}
private void appendAddItem(final List<ContasPagar> novaLista){
runOnUiThread(new Runnable(){
@Override
public void run(){
adapterNormal.notifyDataSetChanged();
}
});
}

If you can hard-code the number of players
Player[] thePlayers = {
new Player(0),
new Player(1),
new Player(2),
new Player(3)
};
