A few thing you could do:
[Optional] Try including both a 'name' and an 'id' attribute e.g.
<input type="text" name="firstname" id="firstname">
If you are in a Linux environment, check that you have both Read/Write permissions to the file.
In addition, this link might also help.
EDIT:
You could also substitute
<code>if(isset($_POST['submit'])){</code>
with this:
<code>if($_SERVER['REQUEST_METHOD'] == "POST"){ </code>
This is always the best way of checking whether or not a form has been submitted
A solution that actually works and covers all cases:
offsetBy
not insetBy
.Rect
.Sample:
override func textRect(forBounds bounds: CGRect) -> CGRect {
return super.textRect(forBounds: bounds).offsetBy(dx: 0.0, dy: 4)
}
override func editingRect(forBounds bounds: CGRect) -> CGRect {
return super.editingRect(forBounds: bounds).offsetBy(dx: 0.0, dy: 4)
}

I actually use a makefile to build any dependencies needed before invoking devenv to build a particular project as in the following:
debug: coratools_debug
devenv coralib.vcproj /build debug
coratools_debug: nothing
cd ../coratools
nmake debug
cd $(MAKEDIR)
You can also use the msbuild tool to do the same thing:
debug: coratools_debug
msbuild coralib.vcxproj /p:Configuration=debug
coratools_debug: nothing
cd ../coratools
nmake debug
cd $(MAKEDIR)
In my opinion, this is much easier than trying to figure out the overly complicated visual studio project management scheme.
We found it practical and useful to put the version in the URL. It makes it easy to tell what you're using at a glance. We do alias /foo to /foo/(latest versions) for ease of use, shorter / cleaner URLs, etc, as the accepted answer suggests.
Keeping backwards compatibility forever is often cost-prohibitive and/or very difficult. We prefer to give advanced notice of deprecation, redirects like suggested here, docs, and other mechanisms.

IsNullOrWhiteSpace
is a convenience method that is similar to the following code, except that it offers superior performance:return String.IsNullOrEmpty(value) || value.Trim().Length == 0;
White-space characters are defined by the Unicode standard. The
IsNullOrWhiteSpace
method interprets any character that returns a value of true when it is passed to theChar.IsWhiteSpace
method as a white-space character.
Your function is failing because the groupby dataframe you end up with has a hierarchical index and two columns (Letter and N) so when you do .hist()
it's trying to make a histogram of both columns hence the str error.
This is the default behavior of pandas plotting functions (one plot per column) so if you reshape your data frame so that each letter is a column you will get exactly what you want.
df.reset_index().pivot('index','Letter','N').hist()
The reset_index()
is just to shove the current index into a column called index
. Then pivot
will take your data frame, collect all of the values N
for each Letter
and make them a column. The resulting data frame as 400 rows (fills missing values with NaN
) and three columns (A, B, C
). hist()
will then produce one histogram per column and you get format the plots as needed.
You need to setup your app to run over https for localhost
You can follow steps given in this to setup HTTPS on ubuntu
You need to do following steps:
install apache (if you do not have)
sudo apt-get install apache2
Step One—Activate the SSL Module
sudo a2enmod ssl
sudo service apache2 restart
Step Two—Create a New Directory
sudo mkdir /etc/apache2/ssl
Step Three—Create a Self Signed SSL Certificate
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache/ssl/apache.key -out /etc/apache2/ssl/apache.crt
With this command, we will be both creating the self-signed SSL certificate and the server key that protects it, and placing both of them into the new directory. The most important line is "Common Name". Enter your official domain name here or, if you don't have one yet, your site's IP address.
Common Name (e.g. server FQDN or YOUR name) []:example.com or localhost
Step Four—Set Up the Certificate
sudo vim /etc/apache2/sites-available/default-ssl
Find following lines and edit those with your settings
ServerName localhost or example.com
SSLEngine on SSLCertificateFile /etc/apache2/ssl/apache.crt
SSLCertificateKeyFile /etc/apache2/ssl/apache.key
Step Five—Activate the New Virtual Host
sudo a2ensite default-ssl
sudo service apache2 reload

SepMiles = "."
End If
If InStr(CurAsTexto, SepDecimal) > 0 Then
If InStr(CurAsTexto, SepMiles) > 0 Then
''//both symbols was used find out what was correct
If InStr(CurAsTexto, SepDecimal) > InStr(CurAsTexto, SepMiles) Then
''// The usage was correct, but get rid of thousand separator
CurAsTexto = Replace(CurAsTexto, SepMiles, "")
Else
''// The usage was incorrect, but get rid of decimal separator and then replace it
CurAsTexto = Replace(CurAsTexto, SepDecimal, "")
CurAsTexto = Replace(CurAsTexto, SepMiles, SepDecimal)
End If
End If
Else
CurAsTexto = Replace(CurAsTexto, SepMiles, SepDecimal)
End If
''// At last we try to tryParse, just in case
Dim retval As Decimal = DefaultValue

bobince's answer will let you know in which cases "height: XX%;" will or won't work.
If you want to create an element with a set ratio (height: % of it's own width), the best way to do that is by effectively setting the height using padding-bottom
. Example for square:
<div class="square-container">
<div class="square-content">
<!-- put your content in here -->
</div>
</div>
.square-container { /* any display: block; element */
position: relative;
height: 0;
padding-bottom: 100%; /* of parent width */
}
.square-content {
position: absolute;
left: 0;
top: 0;
height: 100%;
width: 100%;
}
The square container will just be made of padding, and the content will expand to fill the container. Long article from 2009 on this subject: http://alistapart.com/article/creating-intrinsic-ratios-for-video
A minimalist implementation of the \url
macro that uses only Tex primitives:
\def\url#1{\expandafter\string\csname #1\endcsname}
This url absolutely won't break over lines, though; the hypperef package is better for that.

If you want the image to load and display a particular image, then use .src
to load that image URL.
If you want a piece of meta data (on any tag) that can contain a URL, then use data-src
or any data-xxx
that you want to select.
MDN documentation on data-xxxx attributes: https://developer.mozilla.org/en-US/docs/DOM/element.dataset
Example of src
on an image tag where the image loads the JPEG for you and displays it:
<img id="myImage" src="http://mydomain.com/foo.jpg">
<script>
var imageUrl = document.getElementById("myImage").src;
</script>
Example of 'data-src' on a non-image tag where the image is not loaded yet - it's just a piece of meta data on the div tag:
<div id="myDiv" data-src="http://mydomain.com/foo.jpg">
<script>
// in all browsers
var imageUrl = document.getElementById("myDiv").getAttribute("data-src");
// or in modern browsers
var imageUrl = document.getElementById("myDiv").dataset.src;
</script>
Example of data-src
on an image tag used as a place to store the URL of an alternate image:
<img id="myImage" src="http://mydomain.com/foo.jpg" data-src="http://mydomain.com/foo.jpg">
<script>
var item = document.getElementById("myImage");
// switch the image to the URL specified in data-src
item.src = item.dataset.src;
</script>
Use element.innerHTML="some \\\\n some";
.
NEW_VAR=""
if [[ ${ENV_VAR} && ${ENV_VAR-x} ]]; then
NEW_VAR=${ENV_VAR}
else
NEW_VAR="new value"
fi
Various browsers (mis)handle this in various ways. Using title (an old IE 'standard') isn't particularly appropriate, since the title attribute is a mouseover effect. The jQuery solution above (Alexis) seems on the right track, but I don't think the 'error' occurs at a point where it could be caught. I've had success by replacing at the src with itself, and then catching the error:
$('img').each(function()
{
$(this).error(function()
{
$(this).replaceWith(this.alt);
}).attr('src',$(this).prop('src'));
});
This, as in the Alexis contribution, has the benefit of removing the missing img image.
If you have web services, check your URL pointing to the service. I had a simular issue which was fixed when I changed my web service URL.
Got this idea from @Reid of pushing something in the place of the item that is supposed to be moved to keep the array size constant. That does simplify calculations. Also, pushing an empty object has the added benefits of being able to search for it uniquely later on. This works because two objects are not equal until they are referring to the same object.
({}) == ({}); // false
So here's the function which takes in the source array, and the source, destination indexes. You could add it to the Array.prototype if needed.
function moveObjectAtIndex(array, sourceIndex, destIndex) {
var placeholder = {};
// remove the object from its initial position and
// plant the placeholder object in its place to
// keep the array length constant
var objectToMove = array.splice(sourceIndex, 1, placeholder)[0];
// place the object in the desired position
array.splice(destIndex, 0, objectToMove);
// take out the temporary object
array.splice(array.indexOf(placeholder), 1);
}
public List<DealsCategory> DealCategory { get; set; }
int categoryid = Convert.ToInt16(dealsModel.DealCategory.Select(x => x.Id));
\b is used as word boundary
word = "categorical cat"
Find all "cat" in the above word
without \b
re.findall(r'cat',word)
['cat', 'cat']
with \b
re.findall(r'\bcat\b',word)
['cat']
Uses .each()
, .replace()
, .html()
. Tested with jQuery 1.11 and 3.2.
In the above example, reads the 'keyword' to be highlighted and appends span tag with the 'highlight' class. The text 'keyword' is highlighted for all selected classes in the .each()
.
HTML
<body>
<label name="lblKeyword" id="lblKeyword" class="highlight">keyword</label>
<p class="filename">keyword</p>
<p class="content">keyword</p>
<p class="system"><i>keyword</i></p>
</body>
JS
$(document).ready(function() {
var keyWord = $("#lblKeyword").text();
var replaceD = "<span class='highlight'>" + keyWord + "</span>";
$(".system, .filename, .content").each(function() {
var text = $(this).text();
text = text.replace(keyWord, replaceD);
$(this).html(text);
});
});
CSS
.highlight {
background-color: yellow;
}
Use a generator together with any
, which short-circuits on the first True:
if any(ext in url_string for ext in extensionsToCheck):
print(url_string)
EDIT: I see this answer has been accepted by OP. Though my solution may be "good enough" solution to his particular problem, and is a good general way to check if any strings in a list are found in another string, keep in mind that this is all that this solution does. It does not care WHERE the string is found e.g. in the ending of the string. If this is important, as is often the case with urls, you should look to the answer of @Wladimir Palant, or you risk getting false positives.
using System.IO;
this next code contains 2 methods of reading the text, the first will read single lines and stores them in a string variable, the second one reads the whole text and saves it in a string variable(including "\n" (enters))
both should be quite easy to understand and use.
string pathToFile = "";//to save the location of the selected object
private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
OpenFileDialog theDialog = new OpenFileDialog();
theDialog.Title = "Open Text File";
theDialog.Filter = "TXT files|*.txt";
theDialog.InitialDirectory = @"C:\";
if (theDialog.ShowDialog() == DialogResult.OK)
{
MessageBox.Show(theDialog.FileName.ToString());
pathToFile = theDialog.FileName;//doesn't need .tostring because .filename returns a string// saves the location of the selected object
}
if (File.Exists(pathToFile))// only executes if the file at pathtofile exists//you need to add the using System.IO reference at the top of te code to use this
{
//method1
string firstLine = File.ReadAllLines(pathToFile).Skip(0).Take(1).First();//selects first line of the file
string secondLine = File.ReadAllLines(pathToFile).Skip(1).Take(1).First();
//method2
string text = "";
using(StreamReader sr =new StreamReader(pathToFile))
{
text = sr.ReadToEnd();//all text wil be saved in text enters are also saved
}
}
}
To split the text you can use .Split(" ") and use a loop to put the name back into one string. if you don't want to use .Split() then you could also use foreach and ad an if statement to split it where needed.
to add the data to your class you can use the constructor to add the data like:
public Employee(int EMPLOYEENUM, string NAME, string ADRESS, double WAGE, double HOURS)
{
EmployeeNum = EMPLOYEENUM;
Name = NAME;
Address = ADRESS;
Wage = WAGE;
Hours = HOURS;
}
or you can add it using the set by typing .variablename after the name of the instance(if they are public and have a set this will work). to read the data you can use the get by typing .variablename after the name of the instance(if they are public and have a get this will work).
There might be a fix to <input type="button">
- but if there is, I don't know it.
Otherwise, a good option seems to be to replace it with a carefully styled a
element.
Example: http://jsfiddle.net/Uka5v/
.button {
background-color: #E3E1B8;
padding: 2px 4px;
font: 13px sans-serif;
text-decoration: none;
border: 1px solid #000;
border-color: #aaa #444 #444 #aaa;
color: #000
}
Upsides include that the a
element will style consistently between different (older) versions of Internet Explorer without any extra work, and I think my link looks nicer than that button :)
Also remember you can include custom indices to the array sent to the server like this
<form method='post' id='userform' action='thisform.php'>
<tr>
<td>Trouble Type</td>
<td>
<input type='checkbox' name='checkboxvar[4]' value='Option One'>4<br>
<input type='checkbox' name='checkboxvar[6]' value='Option Two'>6<br>
<input type='checkbox' name='checkboxvar[9]' value='Option Three'>9
</td>
</tr>
<input type='submit' class='buttons'>
</form>
This is particularly useful when you want to use the id
of individual objects in a server array accounts
(for instance) to send data back to the server and recognize same at server
<form method='post' id='userform' action='thisform.php'>
<tr>
<td>Trouble Type</td>
<td>
<?php foreach($accounts as $account) { ?>
<input type='checkbox' name='accounts[<?php echo $account->id ?>]' value='<?php echo $account->name ?>'>
<?php echo $account->name ?>
<br>
<?php } ?>
</td>
</tr>
<input type='submit' class='buttons'>
</form>
<?php
if (isset($_POST['accounts']))
{
print_r($_POST['accounts']);
}
?>
The colClasses vector must have length equal to the number of imported columns. Supposing the rest of your dataset columns are 5:
colClasses=c("character",rep("numeric",5))
Had you tried creating a .jar file manually instead of using Eclipse. Try the following steps, hopefully that might help :
Considering that your directory structure looks like this :
TicTacToe(Your Project Name I mean)
| | |
src bin manifest.txt
| |
icons tictactoe
Now suppose that my main class is BeginGame
inside package tictactoe
, so I will write inside my manifest.txt file this thing :
Main-Class: tictactoe.BeginGame
Do remember the space between colons :
and package name i.e. tictactoe
, and immediately after BeginGame
press Enter and save the file.
Now on your command prompt go to the location of bin folder, I am describing my side as follows :
C:\Mine\Eclipse\TicTacToe\bin>jar -cfm ..\tictactoe.jar ..\manifest.txt tictactoe icons
..\tictactoe.jar
is used to tell that create tictactoe.jar one level up, i.e. inside TicTacToe Folder
...\manifest.txt
means that the manifest.txt file is located one level up, i.e. inside TicTacToe Folder
.tictactoe
and icons
means, that add both these folders to the .jar
file, since they are placed inside bin
Folder so they are used as it is. Now Press Enter.Now try to run your .jar file so created inside the Project Folder
(TicTacToe Folder, in my case).
Hopefully this will work.
Your second bit of code starts the first bit of code as a subprocess with piped input and output. It then closes its input and tries to read its output.
The first bit of code tries to read from standard input, but the process that started it closed its standard input, so it immediately reaches an end-of-file, which Python turns into an exception.
I found the AXMLPrinter2, a Java app over at the Android4Me project to work fine on the AndroidManifest.xml that I had (and prints the XML out in a nicely formatted way). http://code.google.com/p/android4me/downloads/detail?name=AXMLPrinter2.jar
One note.. it (and the code on this answer from Ribo) doesn't appear to handle every compiled XML file that I've come across. I found one where the strings were stored with one byte per character, rather than the double byte format that it assumes.
You can do this without nohup:
ssh user@host 'myprogram >out.log 2>err.log &'
Use empty()
. It checks for both empty strings and null.
if (!empty($_POST['user'])) {
// do stuff
}
From the manual:
The following things are considered to be empty:
"" (an empty string)
0 (0 as an integer)
0.0 (0 as a float)
"0" (0 as a string)
NULL
FALSE
array() (an empty array)
var $var; (a variable declared, but without a value in a class)

For iTextSharp 4.1.6, the last version of iTextSharp that was licensed as LGPL, the solution provided by Alvaro Patiño is both simple and effective.
Because documentation is somewhat scarse I'd like to extend his answer with this code snippet that can be used to change the appearance of the header and footer. By default they have a rather large font-size and a thick border, which many people will want to change.
// Parameters passed on to the function that creates the PDF
String headerText = "Your header text";
String footerText = "Page";
// Define a font and font-size in points (plus f for float) and pick a color
// This one is for both header and footer but you can also create seperate ones
Font fontHeaderFooter = FontFactory.GetFont("arial", 8f);
fontHeaderFooter.Color = Color.GRAY;
// Apply the font to the headerText and create a Phrase with the result
Chunk chkHeader = new Chunk(headerText, fontHeaderFooter);
Phrase p1 = new Phrase(chkHeader);
// create a HeaderFooter element for the header using the Phrase
// The boolean turns numbering on or off
HeaderFooter header = new HeaderFooter(p1, false);
// Remove the border that is set by default
header.Border = Rectangle.NO_BORDER;
// Align the text: 0 is left, 1 center and 2 right.
header.Alignment = 1;
// add the header to the document
document.Header = header;
// The footer is created in an similar way
// If you want to use numbering like in this example, add a whitespace to the
// text because by default there's no space in between them
if (footerText.Substring(footerText.Length - 1) != " ") footerText += " ";
Chunk chkFooter = new Chunk(footerText, fontHeaderFooter);
Phrase p2 = new Phrase(chkFooter);
// Turn on numbering by setting the boolean to true
HeaderFooter footer = new HeaderFooter(p2, true);
footer.Border = Rectangle.NO_BORDER;
footer.Alignment = 1;
document.Footer = footer;
// Open the Document for writing and continue creating its content
document.Open();

You can use, pathlib also
from pathlib import Path
fl = Path("file_name")
fl.chmod(0o444)
Another possibility is to use the options with data
attributes, like this(minimum date 1 week before):
<input class='datepicker' data-date-start-date="-1w">
More info: http://bootstrap-datepicker.readthedocs.io/en/latest/options.html
You're close
sudo apt-get install php-xml
Then you need to restart apache so it takes effect
sudo service apache2 restart
Just create and save a page token in global variable with window.nextPageToken
. Send this to API server everytime you make a request and have it return the next one with response and you can easily keep track of last token. The below is an example how you can move forward and backward from search results. The key is the offset you send to API based on the nextPageToken that you have saved:
function getPrev() {
var offset = Number(window.nextPageToken) - limit * 2;
if (offset < 0) {
offset = 0;
}
window.nextPageToken = offset;
if (canSubmit(searchForm, offset)) {
searchForm.submit();
}
}
function getNext() {
var offset = Number(window.nextPageToken);
window.nextPageToken = offset;
if (canSubmit(searchForm, offset)) {
searchForm.submit();
}
}
Another approach of doing this, albeit by using a heavier but powerful library - NLTK.
import nltk
fdist = nltk.FreqDist(a)
fdist.values()
fdist.most_common()
@cnicutar and @Pete Becker have already pointed out the possibility of using noskipws
/unsetting skipws
to read a character at a time without skipping over white space characters in the input.
Another possibility would be to use an istreambuf_iterator
to read the data. Along with this, I'd generally use a standard algorithm like std::transform
to do the reading and processing.
Just for example, let's assume we wanted to do a Caesar-like cipher, copying from standard input to standard output, but adding 3 to every upper-case character, so A
would become D
, B
could become E
, etc. (and at the end, it would wrap around so XYZ
converted to ABC
.
If we were going to do that in C, we'd typically use a loop something like this:
int ch;
while (EOF != (ch = getchar())) {
if (isupper(ch))
ch = ((ch - 'A') +3) % 26 + 'A';
putchar(ch);
}
To do the same thing in C++, I'd probably write the code more like this:
std::transform(std::istreambuf_iterator<char>(std::cin),
std::istreambuf_iterator<char>(),
std::ostreambuf_iterator<char>(std::cout),
[](int ch) { return isupper(ch) ? ((ch - 'A') + 3) % 26 + 'A' : ch;});
Doing the job this way, you receive the consecutive characters as the values of the parameter passed to (in this case) the lambda function (though you could use an explicit functor instead of a lambda if you preferred).
If you're open to using a 3rd party library, check out javaxt-core. The javaxt.io.Directory class can be used to copy directories like this:
javaxt.io.Directory input = new javaxt.io.Directory("/source");
javaxt.io.Directory output = new javaxt.io.Directory("/destination");
input.copyTo(output, true); //true to overwrite any existing files
You can also provide a file filter to specify which files you want to copy. There are more examples here:
Alter your field to be INT instead of VARCHAR.
I can not make them INT due to some other depending circumstances.
Then fix the depending circumstances first. Otherwise you are working around the real underlying issue. Using a MySQL CAST is an option, but it's masking your bad schema which should be fixed.
Random random=new Random;
ImageView imageView = (ImageView) view.findViewById(R.id.imageView);
ColorFilter cf = new PorterDuffColorFilter(Color.rgb(random.nextInt(255), random.nextInt(255), random.nextInt(255)),Mode.OVERLAY);
imageView.setImageResource(R.drawable.ic_bg_box);
imageView.setColorFilter(cf);
To loop all rows in a dataframe
you can use:
for x in range(len(date_example.index)):
print date_example['Date'].iloc[x]

Eclipse 4.4.2 Luna JDK : 1.8
From Dockerfile reference:
The
ARG
instruction defines a variable that users can pass at build-time to the builder with the docker build command using the--build-arg <varname>=<value>
flag.The
ENV
instruction sets the environment variable<key>
to the value<value>
.
The environment variables set usingENV
will persist when a container is run from the resulting image.
So if you need build-time customization, ARG
is your best choice.
If you need run-time customization (to run the same image with different settings), ENV
is well-suited.
If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable
Given the number of combinations involved, using ENV
to set those features at runtime is best here.
But you can combine both by:
ARG
ARG
as an ENV
That is, with a Dockerfile including:
ARG var
ENV var=${var}
You can then either build an image with a specific var
value at build-time (docker build --build-arg var=xxx
), or run a container with a specific runtime value (docker run -e var=yyy
)
A couple ways this can be done:
This will make it a square
ul
{
list-style-type: square;
}
This will make it green
li
{
color: #0F0;
}
This will prevent the text from being green
li p
{
color: #000;
}
However that will require that all text within lists be in paragraphs so that the color is not overridden.
A better way is to make an image of a green square and use:
ul
{
list-style: url(green-square.png);
}
i prefer to physically print my tables instead:
CONNECT_SERVER="https://196.168.1.1/"
CONNECT_API_KEY<-"hpphotosmartP9000:8273827"
data.frame = data.frame(1:1000, 1000:2)
connectServer <- Sys.getenv("CONNECT_SERVER")
apiKey <- Sys.getenv("CONNECT_API_KEY")
install.packages('print2print')
print2print::send2printer(connectServer, apiKey, data.frame)
Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.
If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.
Swift 3
let button: UIButton = UIButton()
button.frame = CGRect.init(x: view.frame.width/2, y: view.frame.height/2, width: 100, height: 100)
button.setTitle(“Title Button”, for: .normal)
OK!
The code below is written using ES6 syntaxes but could just as easily be written in ES5 or even less. ES6 is not a requirement to create a "mechanism to loop x times"
If you don't need the iterator in the callback, this is the most simple implementation
const times = x => f => {_x000D_
if (x > 0) {_x000D_
f()_x000D_
times (x - 1) (f)_x000D_
}_x000D_
}_x000D_
_x000D_
// use it_x000D_
times (3) (() => console.log('hi'))_x000D_
_x000D_
// or define intermediate functions for reuse_x000D_
let twice = times (2)_x000D_
_x000D_
// twice the power !_x000D_
twice (() => console.log('double vision'))
_x000D_
If you do need the iterator, you can use a named inner function with a counter parameter to iterate for you
const times = n => f => {_x000D_
let iter = i => {_x000D_
if (i === n) return_x000D_
f (i)_x000D_
iter (i + 1)_x000D_
}_x000D_
return iter (0)_x000D_
}_x000D_
_x000D_
times (3) (i => console.log(i, 'hi'))
_x000D_
Stop reading here if you don't like learning more things ...
But something should feel off about those...
if
statements are ugly — what happens on the other branch ?undefined
— indication of impure, side-effecting function"Isn't there a better way ?"
There is. Let's first revisit our initial implementation
// times :: Int -> (void -> void) -> void
const times = x => f => {
if (x > 0) {
f() // has to be side-effecting function
times (x - 1) (f)
}
}
Sure, it's simple, but notice how we just call f()
and don't do anything with it. This really limits the type of function we can repeat multiple times. Even if we have the iterator available, f(i)
isn't much more versatile.
What if we start with a better kind of function repetition procedure ? Maybe something that makes better use of input and output.
Generic function repetition
// repeat :: forall a. Int -> (a -> a) -> a -> a_x000D_
const repeat = n => f => x => {_x000D_
if (n > 0)_x000D_
return repeat (n - 1) (f) (f (x))_x000D_
else_x000D_
return x_x000D_
}_x000D_
_x000D_
// power :: Int -> Int -> Int_x000D_
const power = base => exp => {_x000D_
// repeat <exp> times, <base> * <x>, starting with 1_x000D_
return repeat (exp) (x => base * x) (1)_x000D_
}_x000D_
_x000D_
console.log(power (2) (8))_x000D_
// => 256
_x000D_
Above, we defined a generic repeat
function which takes an additional input which is used to start the repeated application of a single function.
// repeat 3 times, the function f, starting with x ...
var result = repeat (3) (f) (x)
// is the same as ...
var result = f(f(f(x)))
Implementing times
with repeat
Well this is easy now; almost all of the work is already done.
// repeat :: forall a. Int -> (a -> a) -> a -> a_x000D_
const repeat = n => f => x => {_x000D_
if (n > 0)_x000D_
return repeat (n - 1) (f) (f (x))_x000D_
else_x000D_
return x_x000D_
}_x000D_
_x000D_
// times :: Int -> (Int -> Int) -> Int _x000D_
const times = n=> f=>_x000D_
repeat (n) (i => (f(i), i + 1)) (0)_x000D_
_x000D_
// use it_x000D_
times (3) (i => console.log(i, 'hi'))
_x000D_
Since our function takes i
as an input and returns i + 1
, this effectively works as our iterator which we pass to f
each time.
We've fixed our bullet list of issues too

JavaScript comma operator, the
In case you're having trouble seeing how the last example is working, it depends on your awareness of one of JavaScript's oldest battle axes; the comma operator – in short, it evaluates expressions from left to right and returns the value of the last evaluated expression
(expr1 :: a, expr2 :: b, expr3 :: c) :: c
In our above example, I'm using
(i => (f(i), i + 1))
which is just a succinct way of writing
(i => { f(i); return i + 1 })
Tail Call Optimisation
As sexy as the recursive implementations are, at this point it would be irresponsible for me to recommend them given that no JavaScript VM I can think of supports proper tail call elimination – babel used to transpile it, but it's been in "broken; will reimplement" status for well over a year.
repeat (1e6) (someFunc) (x)
// => RangeError: Maximum call stack size exceeded
As such, we should revisit our implementation of repeat
to make it stack-safe.
The code below does use mutable variables n
and x
but note that all mutations are localized to the repeat
function – no state changes (mutations) are visible from outside of the function
// repeat :: Int -> (a -> a) -> (a -> a)_x000D_
const repeat = n => f => x =>_x000D_
{_x000D_
let m = 0, acc = x_x000D_
while (m < n)_x000D_
(m = m + 1, acc = f (acc))_x000D_
return acc_x000D_
}_x000D_
_x000D_
// inc :: Int -> Int_x000D_
const inc = x =>_x000D_
x + 1_x000D_
_x000D_
console.log (repeat (1e8) (inc) (0))_x000D_
// 100000000
_x000D_
This is going to have a lot of you saying "but that's not functional !" – I know, just relax. We can implement a Clojure-style loop
/recur
interface for constant-space looping using pure expressions; none of that while
stuff.
Here we abstract while
away with our loop
function – it looks for a special recur
type to keep the loop running. When a non-recur
type is encountered, the loop is finished and the result of the computation is returned
const recur = (...args) =>_x000D_
({ type: recur, args })_x000D_
_x000D_
const loop = f =>_x000D_
{_x000D_
let acc = f ()_x000D_
while (acc.type === recur)_x000D_
acc = f (...acc.args)_x000D_
return acc_x000D_
}_x000D_
_x000D_
const repeat = $n => f => x =>_x000D_
loop ((n = $n, acc = x) =>_x000D_
n === 0_x000D_

const inc = x =>_x000D_

_x000D_
console.log (repeat (1e7) (inc) (0)) // 10000000_x000D_
console.log (fibonacci (100)) // 354224848179262000000

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

//or
http://127.0.0.1:3000/api/v1/tours/5/10/8987
if faceing that error like geocoding access denied : so you can enable geocoding api service from getKey account.enter image description here
I was trying to solve the same with a list of objects and was having issues because I was trying to repack the list of groups into the original list. So I came up with looping through the groups to repack the original List with items that have duplicates.
public List<MediaFileInfo> GetDuplicatePictures()
{
List<MediaFileInfo> dupes = new List<MediaFileInfo>();
var grpDupes = from f in _fileRepo
group f by f.Length into grps
where grps.Count() >1
select grps;
foreach (var item in grpDupes)
{
foreach (var thing in item)
{
dupes.Add(thing);
}
}
return dupes;
}
It's quite simple. For example, instead of writing:
INSERT INTO x (id, parent_id, code) VALUES (
NULL,
(SELECT id FROM x WHERE code='AAA'),
'BBB'
);
you should write
INSERT INTO x (id, parent_id, code)
VALUES (
NULL,
(SELECT t.id FROM (SELECT id, code FROM x) t WHERE t.code='AAA'),
'BBB'
);
or similar.
Indeed, in the latest version of Spring Data, findOne returns an optional. If you want to retrieve the object from the Optional, you can simply use get() on the Optional. First of all though, a repository should return the optional to a service, which then handles the case in which the optional is empty. afterwards, the service should return the object to the controller.
Here is Something I did
var ImgRotator = {
angle:parseInt(45),
image:{},
src:"",
canvasID:"",
intervalMS:parseInt(500),
jump:parseInt(5),
start_action:function(canvasID, imgSrc, interval, jumgAngle){
ImgRotator.jump = jumgAngle;
ImgRotator.intervalMS = interval;
ImgRotator.canvasID = canvasID;
ImgRotator.src = imgSrc ;
var image = new Image();
var canvas = document.getElementById(ImgRotator.canvasID);
image.onload = function() {
ImgRotator.image = image;
canvas.height = canvas.width = Math.sqrt( image.width* image.width+image.height*image.height);
window.setInterval(ImgRotator.keepRotating,ImgRotator.intervalMS);
//theApp.keepRotating();
};
image.src = ImgRotator.src;
},
keepRotating:function(){
ImgRotator.angle+=ImgRotator.jump;
var canvas = document.getElementById(ImgRotator.canvasID);
var ctx = canvas.getContext("2d");
ctx.save();
ctx.clearRect(0,0,canvas.width,canvas.height);
ctx.translate(canvas.width/2,canvas.height/2);
ctx.rotate(ImgRotator.angle*Math.PI/180);
ctx.drawImage(ImgRotator.image, -ImgRotator.image.width/2,-ImgRotator.image.height/2);
ctx.restore();
}
}

Yeah you can use reflections to access private variables. Altough not a good idea.

I usually use
if(!(jQuery.inArray("test", myarray) < 0))
or
if(jQuery.inArray("test", myarray) >= 0)
String temp = s.Replace("\r\n","").Trim();
s
being the original string. (Note capitals)
In my case the problem was that I hadn't Debug view open in Debug perspective, so:
1 - Be sure you have debug perspective opened:
2 - Be sure you have debug view opened:
I always put the code below in the first two lines of the python files:

If you want to extract from a
tag then
$('.dep_buttons').text().substr(0,25)
With the mouseover event,
$(this).text($(this).text().substr(0, 25));
The above will extract the text of a tag, then extract again assign it back.

The answers here do an excellent job in defining both monoids and monads, however, they still don't seem to answer the question:
And on a less important note, is this true and if so could you give an explanation (hopefully one that can be understood by someone who doesn't have much Haskell experience)?
The crux of the matter that is missing here, is the different notion of "monoid", the so-called categorification more precisely -- the one of monoid in a monoidal category. Sadly Mac Lane's book itself makes it very confusing:
All told, a monad in
X
is just a monoid in the category of endofunctors ofX
, with product×
replaced by composition of endofunctors and unit set by the identity endofunctor.
Why is this confusing? Because it does not define what is "monoid in the category of endofunctors" of X
. Instead, this sentence suggests taking a monoid inside the set of all endofunctors together with the functor composition as binary operation and the identity functor as a monoidal unit. Which works perfectly fine and turns into a monoid any subset of endofunctors that contains the identity functor and is closed under functor composition.
Yet this is not the correct interpretation, which the book fails to make clear at that stage. A Monad f
is a fixed endofunctor, not a subset of endofunctors closed under composition. A common construction is to use f
to generate a monoid by taking the set of all k
-fold compositions f^k = f(f(...))
of f
with itself, including k=0
that corresponds to the identity f^0 = id
. And now the set S
of all these powers for all k>=0
is indeed a monoid "with product × replaced by composition of endofunctors and unit set by the identity endofunctor".
And yet:
S
can be defined for any functor f
or even literally for any self-map of X
. It is the monoid generated by f
.S
given by the functor composition and the identity functor has nothing do with f
being or not being a monad.And to make things more confusing, the definition of "monoid in monoidal category" comes later in the book as you can see from the table of contents. And yet understanding this notion is absolutely critical to understanding the connection with monads.
Going to Chapter VII on Monoids (which comes later than Chapter VI on Monads), we find the definition of the so-called strict monoidal category as triple (B, *, e)
, where B
is a category, *: B x B-> B
a bifunctor (functor with respect to each component with other component fixed) and e
is a unit object in B
, satisfying the associativity and unit laws:
(a * b) * c = a * (b * c)
a * e = e * a = a
for any objects a,b,c
of B
, and the same identities for any morphisms a,b,c
with e
replaced by id_e
, the identity morphism of e
. It is now instructive to observe that in our case of interest, where B
is the category of endofunctors of X
with natural transformations as morphisms, *
the functor composition and e
the identity functor, all these laws are satisfied, as can be directly verified.
What comes after in the book is the definition of the "relaxed" monoidal category, where the laws only hold modulo some fixed natural transformations satisfying so-called coherence relations, which is however not important for our cases of the endofunctor categories.
Finally, in section 3 "Monoids" of Chapter VII, the actual definition is given:
A monoid
c
in a monoidal category(B, *, e)
is an object ofB
with two arrows (morphisms)
mu: c * c -> c
nu: e -> c
making 3 diagrams commutative. Recall that in our case, these are morphisms in the category of endofunctors, which are natural transformations corresponding to precisely join
and return
for a monad. The connection becomes even clearer when we make the composition *
more explicit, replacing c * c
by c^2
, where c
is our monad.
Finally, notice that the 3 commutative diagrams (in the definition of a monoid in monoidal category) are written for general (non-strict) monoidal categories, while in our case all natural transformations arising as part of the monoidal category are actually identities. That will make the diagrams exactly the same as the ones in the definition of a monad, making the correspondence complete.
In summary, any monad is by definition an endofunctor, hence an object in the category of endofunctors, where the monadic join
and return
operators satisfy the definition of a monoid in that particular (strict) monoidal category. Vice versa, any monoid in the monoidal category of endofunctors is by definition a triple (c, mu, nu)
consisting of an object and two arrows, e.g. natural transformations in our case, satisfying the same laws as a monad.
Finally, note the key difference between the (classical) monoids and the more general monoids in monoidal categories. The two arrows mu
and nu
above are not anymore a binary operation and a unit in a set. Instead, you have one fixed endofunctor c
. The functor composition *
and the identity functor alone do not provide the complete structure needed for the monad, despite that confusing remark in the book.
Another approach would be to compare with the standard monoid C
of all self-maps of a set A
, where the binary operation is the composition, that can be seen to map the standard cartesian product C x C
into C
. Passing to the categorified monoid, we are replacing the cartesian product x
with the functor composition *
, and the binary operation gets replaced with the natural transformation mu
from
c * c
to c
, that is a collection of the join
operators
join: c(c(T))->c(T)
for every object T
(type in programming). And the identity elements in classical monoids, which can be identified with images of maps from a fixed one-point-set, get replaced with the collection of the return
operators
return: T->c(T)
But now there are no more cartesian products, so no pairs of elements and thus no binary operations.
The syntax has changed in that print
is now a function. This means that the %
formatting needs to be done inside the parenthesis:1
print("%d. %s appears %d times." % (i, key, wordBank[key]))
However, since you are using Python 3.x., you should actually be using the newer str.format
method:
print("{}. {} appears {} times.".format(i, key, wordBank[key]))
Though %
formatting is not officially deprecated (yet), it is discouraged in favor of str.format
and will most likely be removed from the language in a coming version (Python 4 maybe?).
1Just a minor note: %d
is the format specifier for integers, not %s
.
Assuming you are using VSTS run vsts-npm-auth -config .npmrc

Use btoa()
for encode and atob()
for decode
text_val:any="your encoding text";
Encoded Text: console.log(btoa(this.text_val)); //eW91ciBlbmNvZGluZyB0ZXh0
Decoded Text: console.log(atob("eW91ciBlbmNvZGluZyB0ZXh0")); //your encoding text
Let's dissect it. There are three parts:
cd
-- This is change directory command./d
-- This switch makes cd
change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0
. (%~d0
Changs active drive, cd %~p0
change the directory).%~dp0
-- This can be dissected further into three parts:
%0
-- This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.%~0
-- The ~
there strips double quotes ("
) around the expanded argument.%dp0
-- The d
and p
there are modifiers of the expansion. The d
forces addition of a drive letter and the p
adds full path.You might want to have a look at this specification for CSV. Bear in mind that there is no official recognized specification.
If you do not now the delimiter it will not be possible to do this so you have to find out somehow. If you can do a manual inspection of the file you should quickly be able to see what it is and hard code it in your program. If the delimiter can vary your only hope is to be able to deduce if from the formatting of the known data. When Excel imports CSV files it lets the user choose the delimiter and this is a solution you could use as well.
char buffer[64];
int ret = snprintf(buffer, sizeof buffer, "%f", myFloat);
if (ret < 0) {
return EXIT_FAILURE;
}
if (ret >= sizeof buffer) {
/* Result was truncated - resize the buffer and retry.
}
That will store the string representation of myFloat
in myCharPointer
. Make sure that the string is large enough to hold it, though.
snprintf
is a better option than sprintf
as it guarantees it will never write past the size of the buffer you supply in argument 2.
Try the colSums
function
df <- data.frame(x = c(1,2,NA), y = rep(NA, 3))
colSums(is.na(df))

pylab.show()
works but blocks (you need to close the window).
A much more convenient solution is to do pylab.ion()
(interactive mode on) when you start: all (the pylab equivalents of) pyplot.*
commands display their plot immediately. More information on the interactive mode can be found on the official web site.
I also second using the even more convenient ipython -pylab
(--pylab
, in newer versions), which allows you to skip the from … import …
part (%pylab
works, too, in newer IPython versions).
Clean and simple JSfiddle
This will be useful when you want The event to triggered indirectly from a div or a button.
<img id="image-preview" style="height:100px; width:100px;" src="" >
<input style="display:none" id="input-image-hidden" onchange="document.getElementById('image-preview').src = window.URL.createObjectURL(this.files[0])" type="file" accept="image/jpeg, image/png">
<button onclick="HandleBrowseClick('input-image-hidden');" >UPLOAD IMAGE</button>
<script type="text/javascript">
function HandleBrowseClick(hidden_input_image)
{
var fileinputElement = document.getElementById(hidden_input_image);
fileinputElement.click();
}
</script>
Make sure you encode and decode as appropriate.
This example will roundtrip some example text in utf-8 to a csv file and back out to demonstrate:

CATALINA_HOME
vs CATALINA_BASE
If you're running multiple instances, then you need both variables, otherwise only CATALINA_HOME
.
In other words: CATALINA_HOME
is required and CATALINA_BASE
is optional.
CATALINA_HOME
represents the root of your Tomcat installation.
Optionally, Tomcat may be configured for multiple instances by defining
$CATALINA_BASE
for each instance. If multiple instances are not configured,$CATALINA_BASE
is the same as$CATALINA_HOME
.
See: Apache Tomcat 7 - Introduction
Running with separate CATALINA_HOME
and CATALINA_BASE
is documented in RUNNING.txt which say:
The
CATALINA_HOME
andCATALINA_BASE
environment variables are used to specify the location of Apache Tomcat and the location of its active configuration, respectively.You cannot configure
CATALINA_HOME
andCATALINA_BASE
variables in thesetenv
script, because they are used to find that file.
For example:
(4.1) Tomcat can be started by executing one of the following commands:
%CATALINA_HOME%\bin\startup.bat (Windows) $CATALINA_HOME/bin/startup.sh (Unix)
or
%CATALINA_HOME%\bin\catalina.bat start (Windows) $CATALINA_HOME/bin/catalina.sh start (Unix)
In many circumstances, it is desirable to have a single copy of a Tomcat binary distribution shared among multiple users on the same server. To make this possible, you can set the
CATALINA_BASE
environment variable to the directory that contains the files for your 'personal' Tomcat instance.When running with a separate
CATALINA_HOME
andCATALINA_BASE
, the files and directories are split as following:In
CATALINA_BASE
:
bin
- Only: setenv.sh (*nix) or setenv.bat (Windows), tomcat-juli.jarconf
- Server configuration files (including server.xml)lib
- Libraries and classes, as explained belowlogs
- Log and output fileswebapps
- Automatically loaded web applicationswork
- Temporary working directories for web applicationstemp
- Directory used by the JVM for temporary files>In
CATALINA_HOME
:
bin
- Startup and shutdown scriptslib
- Libraries and classes, as explained belowendorsed
- Libraries that override standard "Endorsed Standards". By default it's absent.
The easiest way to check what's your CATALINA_BASE
and CATALINA_HOME
is by running startup.sh
, for example:
$ /usr/share/tomcat7/bin/startup.sh
Using CATALINA_BASE: /usr/share/tomcat7
Using CATALINA_HOME: /usr/share/tomcat7
You may also check where the Tomcat files are installed, by dpkg
tool as below (Debian/Ubuntu):
dpkg -L tomcat7-common
ogdate
is itself a string, why are you trying to access it's value
property that it doesn't have ?
console.log(og_date.split('-'));
You can either create a static method or use the other class as a member of your class calling the function in the constructor.
public class aClass {
private SomeOtherClass oc;
public class aClass( SomeOtherClass otherClass) {
oc = otherClass;
}
public callOtherClassMethod() {
oc.otherClassMethod();
}
}
Managed to do it:
b = pd.read_csv('b.dat')
b.index = pd.to_datetime(b['date'],format='%m/%d/%y %I:%M%p')
b.groupby(by=[b.index.month, b.index.year])
Or
b.groupby(pd.Grouper(freq='M')) # update for v0.21+
{{html_entity_decode ($post->content())}} saved the issue for me with Laravel 4.0. Now My HTML content is interpreted as it should.
Do something like:
def some_function():
return some_other_function()
def some_other_function():
return 42
if you were to run some_function()
it would then run some_other_function()
and returns 42.
EDIT: I originally stated that you shouldn't define a function inside of another but it was pointed out that it is practical to do this sometimes.
One of the JPA ways for getting only particular columns is to ask for a Tuple object.
In your case you would need to write something like this:
CriteriaQuery<Tuple> cq = builder.createTupleQuery();
// write the Root, Path elements as usual
Root<EntityClazz> root = cq.from(EntityClazz.class);
cq.multiselect(root.get(EntityClazz_.ID), root.get(EntityClazz_.VERSION)); //using metamodel
List<Tuple> tupleResult = em.createQuery(cq).getResultList();
for (Tuple t : tupleResult) {
Long id = (Long) t.get(0);
Long version = (Long) t.get(1);
}
Another approach is possible if you have a class representing the result, like T
in your case. T
doesn't need to be an Entity class. If T
has a constructor like:
public T(Long id, Long version)
then you can use T
directly in your CriteriaQuery
constructor:
CriteriaQuery<T> cq = builder.createQuery(T.class);
// write the Root, Path elements as usual
Root<EntityClazz> root = cq.from(EntityClazz.class);
cq.multiselect(root.get(EntityClazz_.ID), root.get(EntityClazz_.VERSION)); //using metamodel
List<T> result = em.createQuery(cq).getResultList();
See this link for further reference.
I use Liya from the Mac App Store, it's free, does the job, and the project is maintained (a month or so between updates as of Jan 2013).
I also test a lot on the device. You can access the SQLITE database on the device by:
Application supports iTunes file sharing
to the info.plist and setting it to YES You can also edit it and copy it back.
EDIT: You can also do this through the Organizer in XCode
You can now view, edit, and re-upload the package to your debug device. This can be really handy for keeping snapshots of different states to try out on other devices.
This isn't a very beautiful answer, but it's what I use to create zero-length vectors:
0[-1] # numeric
""[-1] # character
TRUE[-1] # logical
0L[-1] # integer
A literal is a vector of length 1, and [-1]
removes the first element (the only element in this case) from the vector, leaving a vector with zero elements.
As a bonus, if you want a single NA
of the respective type:
0[NA] # numeric
""[NA] # character
TRUE[NA] # logical
0L[NA] # integer
Using Windows command prompt: adb logcat -d | findstr <package>

*This was first mentioned by jj_, but it took me ages to find it in the comments...
Actually, there is a command to move a collection from one database to another. It's just not called "move" or "copy".
To copy a collection, you can clone it on the same database, then move the cloned collection.
To clone:
> use db1
switched to db db1
> db.source_collection.find().forEach(
function(x){
db.collection_copy.insert(x)
}
);
To move:
> use admin
switched to db admin
> db.runCommand(
{
renameCollection: 'db1.source_collection',
to : 'db2.target_collection'
}
);
The other answers are better for copying the collection, but this is especially useful if you're looking to move it.
Some answers here says that fs.exists
and fs.existsSync
are both deprecated. According to the docs this is no more true. Only fs.exists
is deprected now:
Note that fs.exists() is deprecated, but fs.existsSync() is not. (The callback parameter to fs.exists() accepts parameters that are inconsistent with other Node.js callbacks. fs.existsSync() does not use a callback.)
So you can safely use fs.existsSync() to synchronously check if a file exists.
The blog article is mostly right, but not complete. To have a full understanding of what an odex file does, you have to understand a little about how application files (APK) work.
Applications are basically glorified ZIP archives. The java code is stored in a file called classes.dex and this file is parsed by the Dalvik JVM and a cache of the processed classes.dex file is stored in the phone's Dalvik cache.
An odex is basically a pre-processed version of an application's classes.dex that is execution-ready for Dalvik. When an application is odexed, the classes.dex is removed from the APK archive and it does not write anything to the Dalvik cache. An application that is not odexed ends up with 2 copies of the classes.dex file--the packaged one in the APK, and the processed one in the Dalvik cache. It also takes a little longer to launch the first time since Dalvik has to extract and process the classes.dex file.
If you are building a custom ROM, it's a really good idea to odex both your framework JAR files and the stock apps in order to maximize the internal storage space for user-installed apps. If you want to theme, then simply deodex -> apply your theme -> reodex -> release.
To actually deodex, use small and baksmali:
Just return any kind of list. ArrayList will be fine, its not static.
ArrayList<yourClass> list = new ArrayList<yourClass>();
for (yourClass item : yourArray)
{
list.add(item);
}
You can override values in php.ini from your PHP code using ini_set()
.
For those coming to this with similar problems, this request library allows you to make external http requests seemlessly within your php application. Simplified GET, POST, PATCH, DELETE and PUT requests.
A sample request would be as below
use Libraries\Request;
$data = [
'samplekey' => 'value',
'otherkey' => 'othervalue'
];
$headers = [
'Content-Type' => 'application/json',
'Content-Length' => sizeof($data)
];
$response = Request::post('https://example.com', $data, $headers);
// the $response variable contains response from the request
Documentation for the same can be found in the project's README.md
>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True
So it doesn't matter, they are all the same value.
The only reason all three modules provide a pi
value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.
As of .NET Core 2.0, there is an override that takes a string.
So now you can do "THExxQUICKxxBROWNxxFOX".Split("xx")
.
In addition to all the answers above:
If you are on Android 6.0+ (API Level 23+) you have to explicitly ask for permission to access external storage. Simply having
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
in your manifest won't be enough. You also have actively request the permission in your activity:
//check for permission
if(ContextCompat.checkSelfPermission(this,
Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED){
//ask for permission
requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, READ_EXTERNAL_STORAGE_PERMISSION_CODE);
}
I recommend reading this: http://developer.android.com/training/permissions/requesting.html#perm-request
I think X-Istence is on the right track, but there are a few more improvements you can make to this strategy. First, use:
$pg_dump --schema ...
to dump the tables, sequences, etc and place this file under version control. You'll use this to separate the compatibility changes between your branches.
Next, perform a data dump for the set of tables that contain configuration required for your application to operate (should probably skip user data, etc), like form defaults and other data non-user modifiable data. You can do this selectively by using:
$pg_dump --table=.. <or> --exclude-table=..
This is a good idea because the repo can get really clunky when your database gets to 100Mb+ when doing a full data dump. A better idea is to back up a more minimal set of data that you require to test your app. If your default data is very large though, this may still cause problems though.
If you absolutely need to place full backups in the repo, consider doing it in a branch outside of your source tree. An external backup system with some reference to the matching svn rev is likely best for this though.
Also, I suggest using text format dumps over binary for revision purposes (for the schema at least) since these are easier to diff. You can always compress these to save space prior to checking in.
Finally, have a look at the postgres backup documentation if you haven't already. The way you're commenting on backing up 'the database' rather than a dump makes me wonder if you're thinking of file system based backups (see section 23.2 for caveats).
I had a similer problem with SqlClient on WCF service. My solution was to put that lines in client app.config

In my case I just needed to remove Homebrew's executable using:
sudo rm -f `which brew`
Then reinstall Homebrew:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Another way:
>>> [i for i in range(len(a)) if a[i] > 2]
[2, 5]
In general, remember that while find
is a ready-cooked function, list comprehensions are a general, and thus very powerful solution. Nothing prevents you from writing a find
function in Python and use it later as you wish. I.e.:
>>> def find_indices(lst, condition):
... return [i for i, elem in enumerate(lst) if condition(elem)]
...
>>> find_indices(a, lambda e: e > 2)
[2, 5]
Note that I'm using lists here to mimic Matlab. It would be more Pythonic to use generators and iterators.
It is possible by recreating table.Its work for me please follow following step:

listagg
got recently covered by the ISO SQL standard (SQL:2016). As part of that, it also got an on overflow
clause, which is supported by Oracle 12cR2.
LISTAGG(<expression>, <separator> ON OVERFLOW …)
The on overflow
clause supports a truncate
option (as alternative to the default on overflow error
behavior).
ON OVERFLOW TRUNCATE [<filler>] WITH[OUT] COUNT
The optional defaults to three periods (...) and will be added as last element if truncation happens.
If with count is specified and truncation happens, the number of omitted values is put in brackets and appended to the result.

The primary purpose is to avoid chained indexing and eliminate the SettingWithCopyWarning
.
Here chained indexing is something like dfc['A'][0] = 111
The document said chained indexing should be avoided in Returning a view versus a copy. Here is a slightly modified example from that document:
In [1]: import pandas as pd
In [2]: dfc = pd.DataFrame({'A':['aaa','bbb','ccc'],'B':[1,2,3]})
In [3]: dfc
Out[3]:
A B
0 aaa 1
1 bbb 2
2 ccc 3
In [4]: aColumn = dfc['A']
In [5]: aColumn[0] = 111
SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame
In [6]: dfc
Out[6]:
A B
0 111 1
1 bbb 2
2 ccc 3
Here the aColumn
is a view and not a copy from the original DataFrame, so modifying aColumn
will cause the original dfc
be modified too. Next, if we index the row first:
In [7]: zero_row = dfc.loc[0]
In [8]: zero_row['A'] = 222
SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame
In [9]: dfc
Out[9]:
A B
0 111 1
1 bbb 2
2 ccc 3
This time zero_row
is a copy, so the original dfc
is not modified.
From these two examples above, we see it's ambiguous whether or not you want to change the original DataFrame. This is especially dangerous if you write something like the following:
In [10]: dfc.loc[0]['A'] = 333
SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame
In [11]: dfc
Out[11]:
A B
0 111 1
1 bbb 2
2 ccc 3
This time it didn't work at all. Here we wanted to change dfc
, but we actually modified an intermediate value dfc.loc[0]
that is a copy and is discarded immediately. It’s very hard to predict whether the intermediate value like dfc.loc[0]
or dfc['A']
is a view or a copy, so it's not guaranteed whether or not original DataFrame will be updated. That's why chained indexing should be avoided, and pandas generates the SettingWithCopyWarning
for this kind of chained indexing update.
Now is the use of .copy()
. To eliminate the warning, make a copy to express your intention explicitly:
In [12]: zero_row_copy = dfc.loc[0].copy()
In [13]: zero_row_copy['A'] = 444 # This time no warning
Since you are modifying a copy, you know the original dfc
will never change and you are not expecting it to change. Your expectation matches the behavior, then the SettingWithCopyWarning
disappears.
Note, If you do want to modify the original DataFrame, the document suggests you use loc
:
In [14]: dfc.loc[0,'A'] = 555
In [15]: dfc
Out[15]:
A B
0 555 1
1 bbb 2
2 ccc 3
if echo $var | egrep -q '^[0-9]+$'
Actually this does not work if var is multiline.
ie
var="123
qwer"
Especially if var comes from a file :
var=`cat var.txt`
This is the simplest :
if [ "$var" -eq "$var" ] 2> /dev/null
then echo yes
else echo no

The first parameter of Html.RadioButtonFor() should be the property name you're using, and the second parameter should be the value of that specific radio button. Then they'll have the same name attribute value and the helper will select the given radio button when/if it matches the property value.
Example:
<div class="editor-field">
<%= Html.RadioButtonFor(m => m.Gender, "M" ) %> Male
<%= Html.RadioButtonFor(m => m.Gender, "F" ) %> Female
</div>
Here's a more specific example:
I made a quick MVC project named "DeleteMeQuestion" (DeleteMe prefix so I know that I can remove it later after I forget about it).
I made the following model:
namespace DeleteMeQuestion.Models
{
public class QuizModel
{
public int ParentQuestionId { get; set; }
public int QuestionId { get; set; }
public string QuestionDisplayText { get; set; }
public List<Response> Responses { get; set; }
[Range(1,999, ErrorMessage = "Please choose a response.")]
public int SelectedResponse { get; set; }
}
public class Response
{
public int ResponseId { get; set; }
public int ChildQuestionId { get; set; }
public string ResponseDisplayText { get; set; }
}
}
There's a simple range validator in the model, just for fun. Next up, I made the following controller:
namespace DeleteMeQuestion.Controllers
{
[HandleError]
public class HomeController : Controller
{
public ActionResult Index(int? id)
{
// TODO: get question to show based on method parameter
var model = GetModel(id);
return View(model);
}
[HttpPost]
public ActionResult Index(int? id, QuizModel model)
{
if (!ModelState.IsValid)
{
var freshModel = GetModel(id);
return View(freshModel);
}
// TODO: save selected answer in database
// TODO: get next question based on selected answer (hard coded to 999 for now)
var nextQuestionId = 999;
return RedirectToAction("Index", "Home", new {id = nextQuestionId});
}
private QuizModel GetModel(int? questionId)
{
// just a stub, in lieu of a database
var model = new QuizModel
{
QuestionDisplayText = questionId.HasValue ? "And so on..." : "What is your favorite color?",
QuestionId = 1,
Responses = new List<Response>
{
new Response
{
ChildQuestionId = 2,
ResponseId = 1,
ResponseDisplayText = "Red"
},
new Response
{
ChildQuestionId = 3,
ResponseId = 2,
ResponseDisplayText = "Blue"
},
new Response
{
ChildQuestionId = 4,
ResponseId = 3,
ResponseDisplayText = "Green"
},
}
};
return model;
}
}
}
Finally, I made the following view that makes use of the model:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DeleteMeQuestion.Models.QuizModel>" %>
<asp:Content ContentPlaceHolderID="TitleContent" runat="server">
Home Page
</asp:Content>
<asp:Content ContentPlaceHolderID="MainContent" runat="server">
<% using (Html.BeginForm()) { %>
<div>
<h1><%: Model.QuestionDisplayText %></h1>
<div>
<ul>
<% foreach (var item in Model.Responses) { %>
<li>
<%= Html.RadioButtonFor(m => m.SelectedResponse, item.ResponseId, new {id="Response" + item.ResponseId}) %>
<label for="Response<%: item.ResponseId %>"><%: item.ResponseDisplayText %></label>
</li>
<% } %>
</ul>
<%= Html.ValidationMessageFor(m => m.SelectedResponse) %>
</div>
<input type="submit" value="Submit" />
<% } %>
</asp:Content>
As I understand your context, you have questions with a list of available answers. Each answer will dictate the next question. Hopefully that makes sense from my model and TODO comments.
This gives you the radio buttons with the same name attribute, but different ID attributes.
If you are not sure which commit you want to branch from in advance you can check commits out and examine their code (see source, compile, test) by
git checkout <sha1-of-commit>
once you find the commit you want to branch from you can do that from within the commit (i.e. without going back to the master first) just by creating a branch in the usual way:
git checkout -b <branch_name>
Similar to some of the solutions posted, but in my case I did the status bar transparent and fix the position of the action bar with some negative margin
if (Build.VERSION.SDK_INT >= 21) {
getWindow().setStatusBarColor(Color.TRANSPARENT);
FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) toolbar.getLayoutParams();
lp.setMargins(0, -getStatusBarHeight(), 0, 0);
}
And I used in the toolbar and the root view
android:fitsSystemWindows="true"
I solved this problem by programmatically creating the Labels and Textfields, and then Command-Dragged from the little empty circles on the left of the code to the components on the Storyboard. To illustrate my point: I wrote @IBOutlet weak var HelloLabel: UILabel!
, and then pressed Command and dragged the code into the component on the storyboard.
The workarounds above (thanks!) don't properly address the problem of getting back the objects provided to the deferred's resolve()
method because jQuery calls the done()
and fail()
callbacks with individual parameters, not an array. That means we have to use the arguments
pseudo-array to get all the resolved/rejected objects returned by the array of deferreds, which is ugly:
$.when.apply($,deferreds).then(function() {
var objects=arguments; // The array of resolved objects as a pseudo-array
...
};
Since we passed in an array of deferreds, it would be nice to get back an array of results. It would also be nice to get back an actual array instead of a pseudo-array so we can use methods like Array.sort()
.
Here is a solution inspired by when.js's when.all()
method that addresses these problems:

if (typeof jQuery.when.all === 'undefined') {
jQuery.when.all = function (deferreds) {
return $.Deferred(function (def) {
$.when.apply(jQuery, deferreds).then(
function () {
def.resolveWith(this, [Array.prototype.slice.call(arguments)]);
},
function () {
def.rejectWith(this, [Array.prototype.slice.call(arguments)]);
});
});
}
}
Now you can simply pass in an array of deferreds/promises and get back an array of resolved/rejected objects in your callback, like so:
$.when.all(deferreds).then(function(objects) {
console.log("Resolved objects:", objects);
});
this fails:

DECLARE @nPortalUID AS UNIQUEIDENTIFIER
SET @nPortalUID = CAST(@vPortalUID AS uniqueidentifier)
PRINT @nPortalUID
this works
DECLARE @vPortalUID NVARCHAR(36)
SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
DECLARE @nPortalUID AS UNIQUEIDENTIFIER
SET @nPortalUID = CAST(@vPortalUID AS UNIQUEIDENTIFIER)
PRINT @nPortalUID
the difference is NVARCHAR(36)

If you want to create dock file of lang package then path should be same where your lang package is currently. For example, I created a folder name javaapi
and unzipped the src
zip file, then used the command below.
C:\Users\Techsupport1\Desktop\javaapi\java\lang> javadoc *.java
this will unhide all files and folders on your computer
attrib -r -s -h /S /D
exit() should do it.
If the problem is to find whether the phone's network is connected and fast enough to meet your demands you have to handle all the network types returned by getSubType()
.
It took me an hour or two to research and write this class to do just exactly that, and I thought I would share it with others that might find it useful.

No need to use datetime library. Using the dateutil library there is no need of any format:
>>> from dateutil import parser
>>> s= '25 April, 2020, 2:50, pm, IST'
>>> parser.parse(s)
datetime.datetime(2020, 4, 25, 14, 50)
You need to add reference (System.Web

The null check is really done nice with guard keyword in swift. It improves the code readability and the scope of the variables are still available after the nil checks if you want to use them.
func setXYX -> Void{
guard a != nil else {
return;
}
guard b != nil else {
return;
}
print (" a and b is not null");
}
answer = “True”
myvars = “the answer is” + answer
print(myvars)
That should give you the answer is True easily as you have stored answer as a string by using the quotation marks
In 12c you can make use of the fact that columns which are set from invisible to visible are displayed as the last column of the table: Tips and Tricks: Invisible Columns in Oracle Database 12c
Maybe that is the 'trick' @jeffrey-kemp was talking about in his comment, but the link there does not work anymore.
Example:
ALTER TABLE my_tab ADD (col_3 NUMBER(10));
ALTER TABLE my_tab MODIFY (
col_1 invisible,
col_2 invisible
);
ALTER TABLE my_tab MODIFY (
col_1 visible,
col_2 visible
);
Now col_3 would be displayed first in a SELECT * FROM my_tab
statement.
Note: This does not change the physical order of the columns on disk, but in most cases that is not what you want to do anyway. If you really want to change the physical order, you can use the DBMS_REDEFINITION package.
System variables usually require a restart to become effective. Does it still not work after a restart?
Here's a solution using a lineJoin to round the corners. Works if you just need a solid shape but not so much if you need a thin border that's smaller than the border radius.
function roundedRect(ctx, options) {
ctx.strokeStyle = options.color;
ctx.fillStyle = options.color;
ctx.lineJoin = "round";
ctx.lineWidth = options.radius;
ctx.strokeRect(
options.x+(options.radius*.5),
options.y+(options.radius*.5),
options.width-options.radius,
options.height-options.radius
);
ctx.fillRect(
options.x+(options.radius*.5),
options.y+(options.radius*.5),
options.width-options.radius,
options.height-options.radius
);
ctx.stroke();
ctx.fill();
}
const canvas = document.getElementsByTagName("CANVAS")[0];
let ctx = canvas.getContext('2d');
roundedRect(ctx, {
x: 10,
y: 10,
width: 200,
height: 100,
radius: 10,
color: "red"
});
I think that the Import-Module

You can use CSS Grid Layout. Support is rather wide at the moment: check it on caniuse.
Here is the example on jsfiddle. Also example with tons of text stuff.

</div>
<div class="content">

</div>
<div class="footer">

</div>
</div>
CSS Code:
html, body {

height: 100%;
margin: 0;
}
.container {
width: 100%;
height: 100%;
display: grid;

Let maven generate a batch file to start your application. This is the simplest way to this.
You can use the appassembler-maven-plugin for such purposes.
In the example you give, you're perfectly right, you have to set the title attribute.
If the aria-label
is one tool used by assistive technologies (like screen readers), it is not natively supported on browsers and has no effect on them. It won't be of any help to most of the people targetted by the WCAG (except screen reader users), for instance a person with intellectal disabilities.
The "X" is not sufficient enough to give information to the action led by the button (think about someone with no computer knowledge). It might mean "close", "delete", "cancel", "reduce", a strange cross, a doodle, nothing.
Despite the fact that the W3C seems to promote the aria-label
rather that the title
attribute here: http://www.w3.org/TR/2014/NOTE-WCAG20-TECHS-20140916/ARIA14 in a similar example, you can see that the technology support does not include standard browsers : http://www.w3.org/WAI/WCAG20/Techniques/ua-notes/aria#ARIA14
In fact aria-label
, in this exact situation might be used to give more context to an action:
For instance, blind people do not perceive popups like those of us with good vision, it's like a change of context. "Back to the page" will be a more convenient alternative for a screen reader, when "Close" is more significant for someone with no screen reader.
<button
aria-label="Back to the page"
title="Close" onclick="myDialog.close()">X</button>
Here is how to kill one or more process from a .bat file.
Step 1. Open a preferred text editor and create a new file.
step 2. To kill one process use the 'taskkill' command, with the '/im' parameter that specifies the image name of the process to be terminated. Example:
taskkill /im examplename.exe
To 'force' kill a process use the '/f' parameter which specifies that processes be forcefully terminated. Example:
taskkill /f /im somecorporateprocess.exe
To kill more than one process you rinse and repeat the first part of step 2. Example:
taskkill /im examplename.exe
taskkill /im examplename1.exe
taskkill /im examplename2.exe
or
taskkill /f /im examplename.exe
taskkill /f /im examplename1.exe
taskkill /f /im examplename2.exe
step 3. Save your file to desired location with the .bat extension.
step 4. click newly created bat file to run it.

if (function_exists('curl_file_create')) { // php 5.5+
$cFile = curl_file_create($file_name_with_full_path);
} else { //
$cFile = '@' . realpath($file_name_with_full_path);
}
$post = array('extra_info' => '123456','file_contents'=> $cFile);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);
You can also refer:

Important hint for PHP 5.5+:
Now we should use https://wiki.php.net/rfc/curl-file-upload but if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
I found several posts telling me to run several gpg commands, but they didn't solve the problem because of two things. First, I was missing the debian-keyring package on my system and second I was using an invalid keyserver. Try different keyservers if you're getting timeouts!
Thus, the way I fixed it was:
apt-get install debian-keyring
gpg --keyserver pgp.mit.edu --recv-keys 1F41B907
gpg --armor --export 1F41B907 | apt-key add -
Then running a new "apt-get update" worked flawlessly!
JavaScript will be required, but the amount of code can be kept to a minimum by using an intermediary <output>
element and an oninput
form handler to perform the comparison (patterns and validation could augment this solution, but aren't shown here for sake of simplicity):
<form oninput="result.value=!!p2.value&&(p1.value==p2.value)?'Match!':'Nope!'">
<input type="password" name="p1" value="" required />
<input type="password" name="p2" value="" required />
<output name="result"></output>
</form>
for xampp vm on MacOS capitan, high sierra, MacOS Mojave (10.12+), you can follow these
1. mount /opt/lampp
2. explore the folder
3. open terminal from the folder
4. cd to `htdocs`>yourapp (ex: techaz.co)
5. vim .htaccess
6. paste your .htaccess content (that is suggested on options-permalink.php)
This worked for me:
String dat="02/08/2017";
long date=new SimpleDateFormat("dd/MM/yyyy").parse(dat,newParsePosition(0)).getTime();
java.sql.Date dbDate=new java.sql.Date(date);
System.out.println(dbDate);
At a guess, because it's not used that often. The only reason I could see using it is if your direct parent has overridden some functionality and you're trying to restore it back to the original.
Which seems to me to be against OO principles, since the class's direct parent should be more closely related to your class than the grandparent is.
You can use the pluck
method:
Word_relation::where('word_one', $word_id)->pluck('word_two')->toArray();
For more info on what methods are available for using with collection, you can you can check out the Laravel Documentation.
Found this...
bcp "SELECT top 1 BlobText FROM TableName" queryout "C:\DesinationFolder\FileName.txt" -T -c'

This works on the Spring Tool Suite v 3.1.0.RELEASE, but I'm guessing it's also available on Eclipse as well.
After deleting the artifacts by hand (as stated by palacsint above) in the /username/.m2
directory, re-index the files by doing the following:
Go to:
Windows->Preferences->Maven->User Settings
menu.Click the Reindex
button next to the Local Repository
text box. Click "Apply" then "OK" and you're done.
The code that you have would work, but is executed from the global context, which means that this
refers to the global object.
<script type="text/javascript">
var foo = function(param) {
param.innerHTML = "Not a button";
};
</script>
<button onclick="foo(this)" id="bar">Button</button>
You can also use the non-inline alternative, which attached to and executed from the specific element context which allows you to access the element from this
.
<script type="text/javascript">
document.getElementById('bar').onclick = function() {
this.innerHTML = "Not a button";
};
</script>
<button id="bar">Button</button>

We only have one person entering records, so I execute the following query immediately following the insert:
$result = $conn->query("SELECT * FROM corex ORDER BY id DESC LIMIT 1");
while ($row = $result->fetch_assoc()) {
$id = $row['id'];
}
This retrieves the last id from the database.
I had the same issue until I added Response.Buffer = False. Try changing the code to the following.
Response.Buffer = False Response.ContentType = "application/vnd.ms-excel" Response.AddHeader "Content-Disposition", "attachment; filename=excelTest.xls"
The only problem I have now is that when Excel opens the file I get the following message.
The file you are trying to open, 'FileName[1].xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
When you open the file the data all appears in separate columns, but the spreadsheet is all white, no borders between the cells.
Hope that helps.
Despite finding an enormous number of question about the same problem (1, 2, 3, 4) I have never found an answer that took performance into consideration, even here.
Although multiple working solutions has been already given I would like to do a performance consideration.
EDIT: Thanks to Manatax for pointing out that option 1 does not suffer of performance issues.
Using Option 1 and 2, aka the COLLATE cast approach, can lead to potential bottleneck, cause any index defined on the column will not be used causing a full scan.
Even though I did not try out Option 3, my hunch is that it will suffer the same consequences of option 1 and 2.
Lastly, Option 4 is the best option for very large tables when it is viable. I mean there are no other usage that rely on the original collation.
Consider this simplified query:
SELECT
*
FROM
schema1.table1 AS T1
LEFT JOIN
schema2.table2 AS T2 ON T2.CUI = T1.CUI
WHERE
T1.cui IN ('C0271662' , 'C2919021')
;
In my original example, I had many more joins. Of course, table1 and table2 have different collations. Using the collate operator to cast, it will lead to indexes not being used.
See sql explanation in the picture below.
Visual Query Explanation when using the COLLATE cast
On the other hand, option 4 can take advantages of possible index and led to fast queries.
In the picture below, you can see the same query being run after applied Option 4, aka altering the schema/table/column collation.
In conclusion, if performance are important and you can alter the collation of the table, go for Option 4. If you have to act on a single column, you can use something like this:
ALTER TABLE schema1.table1 MODIFY `field` VARCHAR(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
Although in most general cases the error is quite clearly that file handles have not been closed, I just encountered an instance with JDK7 on Linux that well... is sufficiently ****ed up to explain here.
The program opened a FileOutputStream (fos), a BufferedOutputStream (bos) and a DataOutputStream (dos). After writing to the dataoutputstream, the dos was closed and I thought everything went fine.
Internally however, the dos, tried to flush the bos, which returned a Disk Full error. That exception was eaten by the DataOutputStream, and as a consequence the underlying bos was not closed, hence the fos was still open.
At a later stage that file was then renamed from (something with a .tmp) to its real name. Thereby, the java file descriptor trackers lost track of the original .tmp, yet it was still open !
To solve this, I had to first flush the DataOutputStream myself, retrieve the IOException and close the FileOutputStream myself.
I hope this helps someone.

If you dont have an entry point defined in your manifest invoking java -jar foo.jar
will not work.
Use this command if you dont have a manifest or to run a different main class than the one specified in the manifest:
java -cp foo.jar full.package.name.ClassName
See also instructions on how to create a manifest with an entry point: https://docs.oracle.com/javase/tutorial/deployment/jar/appman.html
If the two ranges to be tested (your given cell and your given range) are not in the same Worksheet
, then Application.Intersect
throws an error. Thus, a way to avoid it is with something like
Sub test_inters(rng1 As Range, rng2 As Range)
If (rng1.Parent.Name = rng2.Parent.Name) Then
Dim ints As Range
Set ints = Application.Intersect(rng1, rng2)
If (Not (ints Is Nothing)) Then
' Do your job
End If
End If
End Sub

This is what operator.itemgetter
is for.
>>> a = [(1, u'abc'), (2, u'def')]
>>> import operator
>>> b = map(operator.itemgetter(0), a)
>>> b
[1, 2]
The itemgetter
statement returns a function that returns the index of the element you specify. It's exactly the same as writing
>>> b = map(lambda x: x[0], a)
But I find that itemgetter
is a clearer and more explicit.
This is handy for making compact sort statements. For example,
>>> c = sorted(a, key=operator.itemgetter(0), reverse=True)
>>> c
[(2, u'def'), (1, u'abc')]
Raising ActionController::RoutingError('not found')
has always felt a little bit strange to me - in the case of an unauthenticated user, this error does not reflect reality - the route was found, the user is just not authenticated.
I happened across config.action_dispatch.rescue_responses
and I think in some cases this is a more elegant solution to the stated problem:
# application.rb
config.action_dispatch.rescue_responses = {
'UnauthenticatedError' => :not_found
}
# my_controller.rb
before_action :verify_user_authentication
def verify_user_authentication
raise UnauthenticatedError if !user_authenticated?
end
What's nice about this approach is:
ActionController::RoutingError
, but you get a more meaningful error message in dev environmentsnot_found
method that needs to be available everywhere.Shutdown hooks execute in all cases where the VM is not forcibly killed. So, if you were to issue a "standard" kill (SIGTERM
from a kill command) then they will execute. Similarly, they will execute after calling System.exit(int)
.
However a hard kill (kill -9
or kill -SIGKILL
) then they won't execute. Similarly (and obviously) they won't execute if you pull the power from the computer, drop it into a vat of boiling lava, or beat the CPU into pieces with a sledgehammer. You probably already knew that, though.
Finalizers really should run as well, but it's best not to rely on that for shutdown cleanup, but rather rely on your shutdown hooks to stop things cleanly. And, as always, be careful with deadlocks (I've seen far too many shutdown hooks hang the entire process)!

As far as installing a custom plugin there is a good walkthrough on GitHub for the rest2mobile library that could be used for any plugin.
Basically the steps are as follows:
You made a simple mistake. Don't worry....
Simply use getElementById
instead getElementsById
true
var first_number = parseInt(document.getElementById("Text1").value);
False
var first_number = parseInt(document.getElementsById("Text1").value);
Thanks ...
Your nameContent
variable is inside the function scope and not visible outside that function so if you want to use the nameContent
outside of the function then declare it global
inside the <script>
tag and use inside functions without the var
keyword as follows
<script language="javascript" type="text/javascript">
var nameContent; // In the global scope
function first(){
nameContent=document.getElementById('full_name').value;
}
function second() {
first();
y=nameContent;
alert(y);
}
second();
</script>

long milliSecondTimeStamp = MILLISECONDS.convert(secondsTimeStamp, SECONDS)
Edit depending on comment
In some versions - as suggested in comments - the exception thrown may be different.
Thus the solution below is slightly modified
Intent launchIntent = null;
try{
launchIntent = getPackageManager().getLaunchIntentForPackage("applicationId");
} catch (Exception ignored) {}
if(launchIntent == null){
startActivity(new Intent(Intent.ACTION_VIEW).setData(Uri.parse("https://play.google.com/store/apps/details?id=" + "applicationId")));
} else {
startActivity(launchIntent);
}
Original Answer
Although answered well, there is a pretty simple implementation that handles if the app is not installed. I do it like this
try{
startActivity(getPackageManager().getLaunchIntentForPackage("applicationId"));
} catch (PackageManager.NameNotFoundException e) {
startActivity(new Intent(Intent.ACTION_VIEW).setData(Uri.parse("https://play.google.com/store/apps/details?id=" + "applicationId")));
}
Replace "applicationId" with the package that you want to open such as com.google.maps, etc.
Use include
if you don't mind your script continuing without loading the file (in case it doesn't exist etc) and you can (although you shouldn't) live with a Warning error message being displayed.
Using require
means your script will halt if it can't load the specified file, and throw a Fatal error.
Another way of doing this is using a Map (HashMap)
with Key, Value pairs representing your object.
Map<Long, Object> map = new HashMap<Long, Object>();
map.put(new Long(1), "one");
map.put(new Long(2), "two");
In JSTL
<c:if test="${not empty map[1]}">
This should return true if the pair exist in the map
This is a two-step process:
you need to create a login to SQL Server for that user, based on its Windows account
CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
you need to grant this login permission to access a database:
USE (your database)
CREATE USER (username) FOR LOGIN (your login name)
Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader
database role to read all tables.
USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'
Just use ajax.abort() for example you could abort any pending ajax request before sending another one like this
//check for existing ajax request
if(ajax){
ajax.abort();
}
//then you make another ajax request
$.ajax(
//your code here
);
There is a module on npm called mssqlhelper
You can install it to your project by npm i mssqlhelper
Example of connecting and performing a query:
var db = require('./index');
db.config({
host: '192.168.1.100'
,port: 1433
,userName: 'sa'
,password: '123'
,database:'testdb'
});
db.query(
'select @Param1 Param1,@Param2 Param2'
,{
Param1: { type : 'NVarChar', size: 7,value : 'myvalue' }
,Param2: { type : 'Int',value : 321 }
}
,function(res){
if(res.err)throw new Error('database error:'+res.err.msg);
var rows = res.tables[0].rows;
for (var i = 0; i < rows.length; i++) {
console.log(rows[i].getValue(0),rows[i].getValue('Param2'));
}
}
);

Depending what size you want your div
to be, you could utilize Bootstrap's built-in component thumbnail
class, along with (or without) the grid system to create borders around each of your div
items.
These examples on Bootstrap's website demonstrates the ease-of-use and lack of need for any special additional CSS
:
<div class="row">
<div class="col-xs-6 col-md-3">
<a href="#" class="thumbnail">
<img src="..." alt="...">
</a>
</div>
...
</div>
which produces the following div
grid items:
or add some additional content:
<div class="row">
<div class="col-sm-6 col-md-4">
<div class="thumbnail">
<img src="..." alt="...">
<div class="caption">
<h3>Thumbnail label</h3>
<p>...</p>
<p>
<a href="#" class="btn btn-primary" role="button">Button</a>
<a href="#" class="btn btn-default" role="button">Button</a>
</p>
</div>
</div>
</div>
</div>
which produces the following div
grid items:
The best practice would be to use traditionnal getters and setters, because of introspection or reflection. There is a way in PHP (exactly like in Java) to obtain the name of a method or of all methods. Such a thing would return "__get" in the first case and "getFirstField", "getSecondField" in the second (plus setters).
More on that: http://php.net/manual/en/book.reflection.php
Here I'm basically wrapping a button in a link. The advantage is that you can post to different action methods in the same form.
<a href="Controller/ActionMethod">
<input type="button" value="Click Me" />
</a>
Adding parameters:
<a href="Controller/ActionMethod?userName=ted">
<input type="button" value="Click Me" />
</a>
Adding parameters from a non-enumerated Model:
<a href="Controller/[email protected]">
<input type="button" value="Click Me" />
</a>
You can do the same for an enumerated Model too. You would just have to reference a single entity first. Happy Coding!
Try SASS http://sass-lang.com/ or LESS http://lesscss.org/

If embed no longer works for you, try with /v

When I did sudo /etc/init.d/php-fpm start
I got the following error:
Starting php-fpm: [28-Mar-2013 16:18:16] ERROR: [pool www] cannot get uid for user 'apache'
I guess /etc/php-fpm.d/www.conf
needs to know the user that the webserver is running as and assumes it's apache when, for nginx, it's actually nginx, and needs to be changed.
How about:
d = d.applymap(lambda x: np.nan if isinstance(x, basestring) and x.isspace() else x)
The applymap
function applies a function to every cell of the dataframe.
The way I'm doing it now is basically like this:
The HTML:
<textarea id="myText">
Lorem ipsum...
</textarea>
<button onclick="sendMail(); return false">Send</button>
The Javascript:
function sendMail() {
var link = "mailto:[email protected]"
+ "[email protected]"
+ "&subject=" + encodeURIComponent("This is my subject")
+ "&body=" + encodeURIComponent(document.getElementById('myText').value)
;
window.location.href = link;
}
This, surprisingly, works rather well. The only problem is that if the body is particularly long (somewhere over 2000 characters), then it just opens a new email but there's no information in it. I suspect that it'd be to do with the maximum length of the URL being exceeded.
You can use:
public YourClass[] AllProducts()
{
try
{
using (UserDataDataContext db = new UserDataDataContext())
{
return db.mrobProducts.Where(x => x.Status == 1)
.OrderBy(x => x.ID)
.Select(x => new YourClass { ID = x.ID, Name = x.Name, Price = x.Price})
.ToArray();
}
}
catch
{
return null;
}
}
And here is YourClass
implementation:
public class YourClass
{
public string Name {get; set;}
public int ID {get; set;}
public int Price {get; set;}
}
And your AllProducts
method's return type must be YourClass[]
.
I tryied some of suggested solutions here, but was not sattisfied with them, so I created my own module. It is called mikro-config
and the main difference is that it honors convention over configuration, so you can just require the module and start using it.
You store your configuration in either plain js, or json files from /config
folder. First it loads default.js
file, then all other files from /config
directory, then it loads environment specific configuration based on $NODE_ENV
variable.
It also allows to override this configuration for local development with local.js
or environment specific /config/env/$NODE_ENV.local.js
.
You can take at look at it here:
but as for this method, I don't understand the purpose of Integer.MAX_VALUE and Integer.MIN_VALUE.
By starting out with smallest
set to Integer.MAX_VALUE
and largest
set to Integer.MIN_VALUE
, they don't have to worry later about the special case where smallest
and largest
don't have a value yet. If the data I'm looking through has a 10
as the first value, then numbers[i]<smallest
will be true (because 10
is <
Integer.MAX_VALUE
) and we'll update smallest
to be 10
. Similarly, numbers[i]>largest
will be true
because 10
is >
Integer.MIN_VALUE
and we'll update largest
. And so on.
Of course, when doing this, you must ensure that you have at least one value in the data you're looking at. Otherwise, you end up with apocryphal numbers in smallest
and largest
.
Note the point Onome Sotu makes in the comments:
...if the first item in the array is larger than the rest, then the largest item will always be Integer.MIN_VALUE because of the else-if statement.
Which is true; here's a simpler example demonstrating the problem (live copy):
public class Example
{
public static void main(String[] args) throws Exception {
int[] values = {5, 1, 2};
int smallest = Integer.MAX_VALUE;
int largest = Integer.MIN_VALUE;
for (int value : values) {
if (value < smallest) {
smallest = value;
} else if (value > largest) {
largest = value;
}
}
System.out.println(smallest + ", " + largest); // 1, 2 -- WRONG
}
}
To fix it, either:
Don't use else
, or
Start with smallest
and largest
equal to the first element, and then loop the remaining elements, keeping the else if
.
Here's an example of that second one (live copy):
public class Example
{
public static void main(String[] args) throws Exception {
int[] values = {5, 1, 2};
int smallest = values[0];
int largest = values[0];
for (int n = 1; n < values.length; ++n) {
int value = values[n];
if (value < smallest) {
smallest = value;
} else if (value > largest) {
largest = value;
}
}
System.out.println(smallest + ", " + largest); // 1, 5
}
}
You don't really need a sub-select:
SELECT a, COUNT(*) AS b,
SUM( CASE WHEN c = 'const' THEN 1 ELSE 0 END ) as d,
from t group by a order by b desc
If you want to view the versions of files a tag is pointing to, you can do a git checkout, though this puts your repository in “detached HEAD” state, which has some ill side effects:
$ git checkout 2.0.0
Note: checking out '2.0.0'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:
git checkout -b <new-branch-name>
HEAD is now at 99ada87... Merge pull request #89 from schacon/appendix-final
$ git checkout 2.0-beta-0.1
Previous HEAD position was 99ada87... Merge pull request #89 from schacon/appendix-final
HEAD is now at df3f601... add atlas.json and cover image
In “detached HEAD” state, if you make changes and then create a commit, the tag will stay the same, but your new commit won’t belong to any branch and will be unreachable, except for by the exact commit hash. Thus, if you need to make changes—say you’re fixing a bug on an older version, for instance—you will generally want to create a branch:
$ git checkout -b version2 v2.0.0
Switched to a new branch 'version2'
If you do this and make a commit, your version2 branch will be slightly different than your v2.0.0 tag since it will move forward with your new changes, so do be careful.
You can use PHPunit default way of showing messages to debug your variables inside your test like this:
$this->assertTrue(false,$your_variable);
This error can occur in Rstudio simply because your "Plots" pane is just barely too small. Try zooming your "Files, Plots, Packages, Help, Viewer" and see if it helps!

Open the Visual Basic Editor. In Excel, hit Alt+F11 if on Windows, Fn+Option+F11 if on a Mac.
Insert a new module. From the menu: Insert -> Module (Don't skip this!).
Create a Public
function. Example:
Public Function findArea(ByVal width as Double, _
ByVal height as Double) As Double
' Return the area
findArea = width * height
End Function
Then use it in any cell like you would any other function: =findArea(B12,C12)

$image_resize = Image::make($image->getRealPath());
$image_resize->resize(800,600);
$image_resize->save(Storage::disk('episodes')->path('') . $imgname);
so you can use it like this
echo Storage::disk('public')->path('');
The answers you got assumed static text to compare against. If you want to compare against another column (say, you're joining two tables, and want to find ones where a column from one table is part of a column from another table), you can do this
WHERE NOT (someColumn LIKE '%' || someOtherColumn || '%')
$('.time-picker').timepicker({
showMeridian: false
});
This will work.
Here is how I do it by using HashSet
HashSet<String> hs = new HashSet<string>(new String[] { "Pluto", "Earth", "Neptune" });
String[] arr =
{
"Pluto",
"Earth",
"Neptune",
"Jupiter",
"Saturn",
"Mercury",
"Pluto",
"Earth",
"Neptune",
"Jupiter",
"Saturn",
"Mercury",
// etc.
};
ICollection<String> coll = arr;
String[] arrStrFiltered = coll.Where(str => hs.Contains(str)).ToArray();
HashSet is basically almost to O(1) so your complexity remains O(n).
Yeah it is possible with FileReader, I have already done an example of this, here's the code:
<!DOCTYPE html>
<html>
<head>
<title>Read File (via User Input selection)</title>
<script type="text/javascript">
var reader; //GLOBAL File Reader object for demo purpose only
/**
* Check for the various File API support.
*/
function checkFileAPI() {
if (window.File && window.FileReader && window.FileList && window.Blob) {
reader = new FileReader();
return true;
} else {
alert('The File APIs are not fully supported by your browser. Fallback required.');
return false;
}
}
/**
* read text input
*/
function readText(filePath) {
var output = ""; //placeholder for text output
if(filePath.files && filePath.files[0]) {
reader.onload = function (e) {
output = e.target.result;
displayContents(output);
};//end onload()
reader.readAsText(filePath.files[0]);
}//end if html5 filelist support
else if(ActiveXObject && filePath) { //fallback to IE 6-8 support via ActiveX
try {
reader = new ActiveXObject("Scripting.FileSystemObject");
var file = reader.OpenTextFile(filePath, 1); //ActiveX File Object
output = file.ReadAll(); //text contents of file
file.Close(); //close file "input stream"
displayContents(output);
} catch (e) {
if (e.number == -2146827859) {
alert('Unable to access local files due to browser security settings. ' +
'To overcome this, go to Tools->Internet Options->Security->Custom Level. ' +
'Find the setting for "Initialize and script ActiveX controls not marked as safe" and change it to "Enable" or "Prompt"');
}
}
}
else { //this is where you could fallback to Java Applet, Flash or similar
return false;
}
return true;
}
/**
* display content using a basic HTML replacement
*/
function displayContents(txt) {
var el = document.getElementById('main');
el.innerHTML = txt; //display output in DOM
}
</script>
</head>
<body onload="checkFileAPI();">
<div id="container">
<input type="file" onchange='readText(this)' />
<br/>
<hr/>
<h3>Contents of the Text file:</h3>
<div id="main">
...
</div>
</div>
</body>
</html>
It's also possible to do the same thing to support some older versions of IE (I think 6-8) using the ActiveX Object, I had some old code which does that too but its been a while so I'll have to dig it up I've found a solution similar to the one I used courtesy of Jacky Cui's blog and edited this answer (also cleaned up code a bit). Hope it helps.
Lastly, I just read some other answers that beat me to the draw, but as they suggest, you might be looking for code that lets you load a text file from the server (or device) where the JavaScript file is sitting. If that's the case then you want AJAX code to load the document dynamically which would be something as follows:
<!DOCTYPE html>
<html>
<head><meta charset="utf-8" />
<title>Read File (via AJAX)</title>
<script type="text/javascript">
var reader = new XMLHttpRequest() || new ActiveXObject('MSXML2.XMLHTTP');
function loadFile() {
reader.open('get', 'test.txt', true);
reader.onreadystatechange = displayContents;
reader.send(null);
}
function displayContents() {
if(reader.readyState==4) {
var el = document.getElementById('main');
el.innerHTML = reader.responseText;
}
}
</script>
</head>
<body>
<div id="container">
<input type="button" value="test.txt" onclick="loadFile()" />
<div id="main">
</div>
</div>
</body>
</html>
To simplify, make sure to add a hash bang to the top of your ExecStart script, i.e.
#!/bin/bash
python -u alwayson.py
Using $ docker inspect
Incase the Image has no /bin/bash
in the output, you can use command below: it worked for me perfectly
$ docker exec -it <container id> sh
On OSX, saving video frames and still images only worked for me when I gave a full path to cvSaveImage:
cvSaveImage("/Users/nicc/image.jpg",img);
Padding by definition is a positive integer (including 0).
Negative padding would cause the border to collapse into the content (see the box-model page on w3) - this would make the content area smaller than the content, which doesn't make sense.
