You can also use START WITH
to start a sequence from a particular point, although setval accomplishes the same thing, as in Euler's answer, eg,
SELECT MAX(a) + 1 FROM foo;
CREATE SEQUENCE foo_a_seq START WITH 12345; -- replace 12345 with max above
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq');
It seems there is an issue with glibc that affects the memory allocation in Pandas: https://github.com/pandas-dev/pandas/issues/2659
The monkey patch detailed on this issue has resolved the problem for me:

You need to give relative
or absolute
or fixed
positioning to your container (#shop
) and set its zIndex
to say 100.
You also need to give say relative
positioning to your elements with the class content
and lower zIndex
say 97.
Do the above-mentioned with your images too and set their zIndex
to 91.
And then position your button higher by setting its position to absolute
and zIndex
to 95

Those messages are something tricky, enough so that people created this to make it clearer: https://issues.apache.org/bugzilla/show_bug.cgi?id=25747
What's tricky about them is that the warnings are written if Log4j can't find its log4j.properties
(or log4j.xml
) file, but also if the file is fine and dandy but its content is not complete from a configuration point of view.
The following paragraph is taken from here: http://svn.apache.org/repos/asf/logging/log4j/tags/v1_2_9/docs/TROUBLESHOOT.html
Logging output is written to a target by using an appender. If no appenders are attached to a category nor to any of its ancestors, you will get the following message when trying to log:
log4j: No appenders could be found for category (some.category.name).
log4j: Please initialize the log4j system properly.
Log4j does not have a default logging target. It is the user's responsibility to ensure that all categories can inherit an appender. This can be easily achieved by attaching an appender to the root category.
You can find info on how to configure the root logger (log4j.rootLogger
) in the log4j documentation, basically adding something as simple as this at the beginning of the file:
log4j.rootLogger=debug, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
This should clear those WARN messages you get on startup (make sure you don't already have an appender named stdout
; also be carefull of what level you give the root logger, debug
will be very verbose and every library in your app will start writing stuff to the console).
As about the log4j.properties
/log4j.xml
, I suggest you place this file in /WEB-INF/classes
as it is important to have it exposed for different tweaks (activating/deactivating logs, changing log levels etc). You can have it inside a JAR in the classpath also (as you specified in your comment), but it will be enclosed in the archive (hopefully in the right place inside the archive) and won't be as easy to handle as if it were in /WEB-INF/classes
.
This approach from Microsoft works very well and provides the option to compare one list to another and switch them to get the difference in each. If you are comparing classes simply add your objects to two separate lists and then run the comparison.
To pass get variables as well use $args
:
location / {
try_files $uri $uri/ /index.php?$args;
}
Your this
doesn't refer to the element in the step callback, instead you want to keep a reference to it at the beginning of your function (wrapped in $this
in my example):
$('.Count').each(function () {
var $this = $(this);
jQuery({ Counter: 0 }).animate({ Counter: $this.text() }, {
duration: 1000,
easing: 'swing',
step: function () {
$this.text(Math.ceil(this.Counter));
}
});
});
Update: If you want to display decimal numbers, then instead of rounding the value with Math.ceil
you can round up to 2 decimals for instance with value.toFixed(2)
:
step: function () {
$this.text(this.Counter.toFixed(2));
}
Be aware of the Input::all()
, it will Include the previous ?page=
values again and again in each page you open !
for example if you are in ?page=1
and you open the next page, it will open ?page=1&page=2
So the last value page takes will be the page you see ! not the page you want to see
Solution : use Input::except(array('page'))
If someone wants vertical version of the treeview from Harsh's answer, you can save some time:

}
/*Connector styles on hover*/
.tree li a:hover+ul li::after,

Few ways of declaring a typed array in TypeScript
are
const booleans: Array<boolean> = new Array<boolean>();
// OR, JS like type and initialization
const booleans: boolean[] = [];
// or, if you have values to initialize
const booleans: Array<boolean> = [true, false, true];
// get a vaue from that array normally
const valFalse = booleans[1];
Ok you can use this simply
-webkit-text-stroke-width: .7px;
-webkit-text-stroke-color: #34343b;
-webkit-font-smoothing:antialiased;
Make sure your text color and upper text-stroke-width must me same and that's it.
I think you just need COUNT(DISTINCT post_id) FROM votes
.
See "4.2.7. Aggregate Expressions" section in http://www.postgresql.org/docs/current/static/sql-expressions.html.
EDIT: Corrected my careless mistake per Erwin's comment.
Below code recursively delete all contents in a given folder.
boolean deleteDirectory(File directoryToBeDeleted) {
File[] allContents = directoryToBeDeleted.listFiles();
if (allContents != null) {
for (File file : allContents) {
deleteDirectory(file);
}
}
return directoryToBeDeleted.delete();
}
An object
behaves like a dictionary because Javascript is dynamically typed, allowing you to add or remove properties at any time.
But Map()
is much better because it:
get
, set
, has
, and delete
methods.for-of
usage and maintains order of results.If you need a dictionary then you should just use a Map()
.
However, if you're only using string-based keys and need maximum read performance, then objects might be a better choice. This is because Javascript engines compile objects down to C++ classes in the background. The access path for properties on these classes is very optimized and much faster than a function call for Map().get()
.
These classes are also cached, so creating a new object with the same exact properties means the engine will reuse an existing background class. Adding or removing a property causes the shape of the class to change and the backing class to be re-compiled, which is why using an object as a dictionary with lots of additions and deletions is very slow, but reads of existing keys without changing the object are very fast.
So if you have a write-once read-heavy workload with string keys then you can use an object
as a high-performance dictionary, but for everything else use a Map()
.
I had this issue also and I simply found out that if you simply remove the "#" the issue goes off. Like this :
<a href="" class="disabled" ng-click="doSomething(object)">Do something</a>
You can check the return value from scanf
. This code will just sit there until it receives a string.
int a;
do {
// other code
a = scanf("%s", url);
} while (a <= 0);
Having had a similar itch to scratch (altough only for some files of a given repository) this script proved to be really helpful: git-import
The short version is that it creates patch files of the given file or directory ($object
) from the existing repository:
cd old_repo
git format-patch --thread -o "$temp" --root -- "$object"
which then get applied to a new repository:
cd new_repo
git am "$temp"/*.patch
For details please look up:
Jenkins Pipeline also provides the current build number as the property number
of the currentBuild
. It can be read as currentBuild.number
.
For example:
// Scripted pipeline
def buildNumber = currentBuild.number
// Declarative pipeline
echo "Build number is ${currentBuild.number}"
Other properties of currentBuild
are described in the Pipeline Syntax: Global Variables page that is included on each Pipeline job page. That page describes the global variables available in the Jenkins instance based on the current plugins.
og:title
is one of the open graph meta tags. og:...
properties define objects in a social graph. They are used for example by Facebook.
og:title
stands for the title of your object as it should appear within the graph (see here for more http://ogp.me/ )

For any Swing component (that is, anything that extends JComponent), you can call the setToolTipText(String) method.
For more information, reference the following links:
Here you go. This solution uses a DataInputStream
to scan for the position of the string you want replaced and uses a FileChannel
to replace the text at that exact position. It only replaces the first occurrence of the string that it finds. This solution doesn't store a copy of the entire file somewhere, (either the RAM or a temp file), it just edits the portion of the file that it finds.
public static long scanForString(String text, File file) throws IOException {
if (text.isEmpty())
return file.exists() ? 0 : -1;
// First of all, get a byte array off of this string:
byte[] bytes = text.getBytes(/* StandardCharsets.your_charset */);
// Next, search the file for the byte array.
try (DataInputStream dis = new DataInputStream(new FileInputStream(file))) {
List<Integer> matches = new LinkedList<>();
for (long pos = 0; pos < file.length(); pos++) {
byte bite = dis.readByte();
for (int i = 0; i < matches.size(); i++) {
Integer m = matches.get(i);
if (bytes[m] != bite)
matches.remove(i--);
else if (++m == bytes.length)
return pos - m + 1;
else
matches.set(i, m);
}
if (bytes[0] == bite)
matches.add(1);
}
}
return -1;
}
public static void replaceText(String text, String replacement, File file) throws IOException {
// Open a FileChannel with writing ability. You don't really need the read
// ability for this specific case, but there it is in case you need it for
// something else.
try (FileChannel channel = FileChannel.open(file.toPath(), StandardOpenOption.WRITE, StandardOpenOption.READ)) {
long scanForString = scanForString(text, file);
if (scanForString == -1) {
System.out.println("String not found.");
return;
}
channel.position(scanForString);
channel.write(ByteBuffer.wrap(replacement.getBytes(/* StandardCharsets.your_charset */)));
}
}

there is an Eclipse app called Import Jar As Project. I think it is quite simple and useful. https://marketplace.eclipse.org/content/import-jar-project?mpc=true&mpc_state=
I'm a little confused. "foo.html" is just the name of your template. There's no inherent relationship between the route name "foo" and the template name "foo.html".
To achieve the goal of not rewriting logic code for two different routes, I would just define a function and call that for both routes. I wouldn't use redirect because that actually redirects the client/browser which requires them to load two pages instead of one just to save you some coding time - which seems mean :-P
So maybe:
def super_cool_logic():
# execute common code here
@app.route("/foo")
def do_foo():
# do some logic here
super_cool_logic()
return render_template("foo.html")
@app.route("/baz")
def do_baz():
if some_condition:
return render_template("baz.html")
else:
super_cool_logic()
return render_template("foo.html", messages={"main":"Condition failed on page baz"})
I feel like I'm missing something though and there's a better way to achieve what you're trying to do (I'm not really sure what you're trying to do)

Like KingCronus mentioned in the comments you can use the row class to make the list or heading on its own line. You could use the row class on either or both elements:
<ul class="nav nav-tabs span2 row">

<li><a href="./about.html"><i class="icon-black icon-eye-open"></i></a></li>
<li><a href="./team.html"><i class="icon-black icon-user"></i></a></li>
<li><a href="./contact.html"><i class="icon-black icon-envelope"></i></a></li>
</ul>
<div class="well span6 row">
<h3>I wish this appeared on the next line without having to gratuitously use BR!</h3>
</div>
One option is to directly input the character you're interested in using hex or octal notation:
printf "\x41\n"
printf "\101\n"
In the R help section, as pointed out above, just disabling quoting altogether, by simply adding:

Apple uses "NSObjectProtocol" instead of "class".
public protocol UIScrollViewDelegate : NSObjectProtocol {

This also works for me and removed the errors I was seeing when trying to implement my own delegate pattern.
Firstly, there is a difference. For numbers

False
And for strings

NullReferenceException
In both cases, ==
behaves more usefully than .Equals

It is very close - our build process for Oracle JDK releases builds on OpenJDK 7 by adding just a couple of pieces, like the deployment code, which includes Oracle's implementation of the Java Plugin and Java WebStart, as well as some closed source third-party components like a graphics rasterizer, some open-source third party components, like Rhino, and a few bits and pieces here and there, like additional documentation or third-party fonts. Moving forward, we intend to open source all pieces of the Oracle JDK except those that we consider commercial features such as JRockit Mission Control (not yet available in Oracle JDK) and replace encumbered third-party components with open source alternatives to achieve closer parity between the codebases.
· Yes, the garbage collection and other JVM parameters are the same.
· The performance of GC is the same in both.
The simpliest way to wrap a function
func(*args, **kwargs)
... is to manually write a wrapper that would call func() inside itself:
def wrapper(*args, **kwargs):
# do something before
try:
return func(*a, **kwargs)
finally:
# do something after
In Python function is an object, so you can pass it's name as an argument of another function and return it. You can also write a wrapper generator for any function anyFunc():
def wrapperGenerator(anyFunc, *args, **kwargs):
def wrapper(*args, **kwargs):
try:
# do something before
return anyFunc(*args, **kwargs)
finally:
#do something after
return wrapper
Please also note that in Python when you don't know or don't want to name all the arguments of a function, you can refer to a tuple of arguments, which is denoted by its name, preceded by an asterisk in the parentheses after the function name:
*args
For example you can define a function that would take any number of arguments:
def testFunc(*args):
print args # prints the tuple of arguments
Python provides for even further manipulation on function arguments. You can allow a function to take keyword arguments. Within the function body the keyword arguments are held in a dictionary. In the parentheses after the function name this dictionary is denoted by two asterisks followed by the name of the dictionary:
**kwargs
A similar example that prints the keyword arguments dictionary:
def testFunc(**kwargs):
print kwargs # prints the dictionary of keyword arguments

Oracle's security model is such that when executing dynamic SQL using Execute Immediate (inside the context of a PL/SQL block or procedure), the user does not have privileges to objects or commands that are granted via role membership. Your user likely has "DBA" role or something similar. You must explicitly grant "drop table" permissions to this user. The same would apply if you were trying to select from tables in another schema (such as sys or system) - you would need to grant explicit SELECT privileges on that table to this user.
You could try changing the: SizeMode property of the PictureBox.
You could also set your image as the BackGroundImage of the PictureBox and try changing the BackGroundImageLayout to the correct mode.
I would prefer it - vec.begin()
precisely for the opposite reason given by Naveen: so it wouldn't compile if you change the vector into a list. If you do this during every iteration, you could easily end up turning an O(n) algorithm into an O(n^2) algorithm.
Another option, if you don't jump around in the container during iteration, would be to keep the index as a second loop counter.
Note: it
is a common name for a container iterator,std::container_type::iterator it;
.
Mr. Curious was curious about this as well. In addition to the #>> '{}'
operator, in 9.6+ one can get the value of a jsonb string with the ->>
operator:
select to_jsonb('Some "text"'::TEXT)->>0;
?column?
-------------
Some "text"
(1 row)
If one has a json value, then the solution is to cast into jsonb first:
select to_json('Some "text"'::TEXT)::jsonb->>0;
?column?
-------------
Some "text"
(1 row)
You can use prop() for this, as Before jQuery 1.6, the .attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior. As of jQuery 1.6, the .prop()
method provides a way to explicitly retrieve property values, while .attr()
retrieves attributes.
var prop=false;
if(value == 1) {
prop=true;
}
$('#checkbox').prop('checked',prop);
or simply,
$('#checkbox').prop('checked',(value == 1));

Basically, the difference between padding and margin come in terms of the background. Padding will decide the space between content, while margin decide the outside edge of elements!
After some research on managing configs for development and builds etc, I decided to roll my own, I have made it available on bitbucket at: https://bitbucket.org/brightertools/contemplate/wiki/Home
This multiple configuration files for multiple environments, its a basic configuration entry replacement tool that will work with any text based file format.
Hope this helps.
you need to initialize the object elements of the array.
GameObject[] houses = new GameObject[200];
for (int i=0;`i<house` i<houses.length; i++)
{ houses[i] = new GameObject();}
Of course you initialize elements selectively using different constructors anywhere else before you reference them.
Add my two cents, if you're using windows commnad line:
git config --list | findstr user.name
will give username directly.
The findstr
here is quite similar to grep
in linux.
By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.
In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.
The client code must set the withCredentials
property on the XMLHttpRequest
to true
in order to give permission.
However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials
header. Responding with this header to true
means that the server allows cookies (or other user credentials) to be included on cross-origin requests.
You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.
Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).

output would be: arr1 arr2
I had the same problem, but calling this.form.controls['name'].disable() did not fixed it because I was reloading my view (using router.navigate()).
In my case I had to reset my form before reloading:
this.form = undefined; this.router.navigate([path]);
I am convinced that it is impossible now. It was, though.
IE7’s implementation of getClientRects did exactly what I want. Open this page in IE8, try refreshing it varying window width, and see how number of lines in the first element changes accordingly. Here’s the key lines of the javascript from that page:
var rects = elementList[i].getClientRects();
var p = document.createElement('p');
p.appendChild(document.createTextNode('\'' + elementList[i].tagName + '\' element has ' + rects.length + ' line(s).'));
Unfortunately for me, Firefox always returns one client rectangle per element, and IE8 does the same now. (Martin Honnen’s page works today because IE renders it in IE compat view; press F12 in IE8 to play with different modes.)
This is sad. It looks like once again Firefox’s literal but worthless implementation of the spec won over Microsoft’s useful one. Or do I miss a situation where new getClientRects may help a developer?
It looks like you forgot to include the ngRoute module in your dependency for myApp.
In Angular 1.2, they've made ngRoute optional (so you can use third-party route providers, etc.) and you have to explicitly depend on it in modules, along with including the separate file.
'use strict';
angular.module('myApp', ['ngRoute']).
config(['$routeProvider', function($routeProvider) {
$routeProvider.otherwise({redirectTo: '/home'});
}]);
Here is some relevant code:
// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}
}
};
// Install the all-trusting trust manager
try {
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
}
// Now you can access an https URL without having the certificate in the truststore
try {
URL url = new URL("https://hostname/index.html");
} catch (MalformedURLException e) {
}
This will completely disable SSL checking—just don't learn exception handling from such code!
To do what you want, you would have to implement a check in your TrustManager that prompts the user.
Please remember that Google also use reCaptcha together with
Canvas fingerprinting
to uniquely recognize User/Browsers without cookies!
That error means that a function call is only matched by an existing function if all its arguments are of the same type and passed in same order. So if the next f()
function
create function f() returns integer as $$
select 1;
$$ language sql;
is called as
select f(1);
It will error out with
ERROR: function f(integer) does not exist
LINE 1: select f(1);
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
because there is no f()
function that takes an integer as argument.
So you need to carefully compare what you are passing to the function to what it is expecting. That long list of table columns looks like bad design.
I use
setTranscriptMode(ListView.TRANSCRIPT_MODE_NORMAL);
to add entries at the bottom, and older entries scroll off the top, like a chat transcript
I met some problems in Clion and finally, I solved them. Here is some experience.
If I'm understanding you correctly, you can simply use .ToString() to retrieve the name of the enum from the value (Assuming it's already cast as the Enum); If you had the naked int (lets say from a database or something) you can first cast it to the enum. Both methods below will get you the enum name.
AuthenticationMethod myCurrentSetting = AuthenticationMethod.FORMS;
Console.WriteLine(myCurrentSetting); // Prints: FORMS
string name = Enum.GetNames(typeof(AuthenticationMethod))[(int)myCurrentSetting-1];
Console.WriteLine(name); // Prints: FORMS
Keep in mind though, the second technique assumes you are using ints and your index is 1 based (not 0 based). The function GetNames also is quite heavy by comparison, you are generating a whole array each time it's called. As you can see in the first technique, .ToString() is actually called implicitly. Both of these are already mentioned in the answers of course, I'm just trying to clarify the differences between them.
Using NewRequest
just to create an URL is an overkill. Use the net/url
package:
package main
import (
"fmt"
"net/url"
)
func main() {
base, err := url.Parse("http://www.example.com")
if err != nil {
return
}
// Path params
base.Path += "this will get automatically encoded"
// Query params
params := url.Values{}
params.Add("q", "this will get encoded as well")
base.RawQuery = params.Encode()
fmt.Printf("Encoded URL is %q\n", base.String())
}

I wanted to add something to the answer already provided. maven-compiler-plugin by default will compile your project using Java 1.5 which is where m2e get's its information.
That's why you have to explicitly declare the maven-compiler-plugin in your project with something other then 1.5. Your effective pom.xml
will implicitly use the default set in the maven-compiler-plugin pom.xml
.
after complete the code first merge branch to master then delete that branch
git checkout master
git merge <branch-name>
git branch -d <branch-name>
Set args = Wscript.Arguments
For Each arg In args
Wscript.Echo arg
Next
From a command prompt, run the script like this:
CSCRIPT MyScript.vbs 1 2 A B "Arg with spaces"
Will give results like this:
1
2
A
B
Arg with spaces
if your eclipse is auto-closing at startup you may do this: open the properties of your shortcut and add -clean at the end of the path. or do this in cmd : cd C:\PATH_TO_YOUR_ECLIPSE\eclipse -clean like mentioned earlier above comments
Threading is another possible solution. Although the Celery based solution is better for applications at scale, if you are not expecting too much traffic on the endpoint in question, threading is a viable alternative.
This solution is based on Miguel Grinberg's PyCon 2016 Flask at Scale presentation, specifically slide 41 in his slide deck. His code is also available on github for those interested in the original source.
From a user perspective the code works as follows:
To convert an api call to a background task, simply add the @async_api decorator.

You can't. and the reason is that they do not "live" in the same time. The Razor variables are "Server side variables" and they don't exist anymore after the page was sent to the "Client side".
When the server get a request for a view, it creates the view with only HTML, CSS and Javascript code. No C# code is left, it's all get "translated" to the client side languages.
The Javascript code DOES exist when the view is still on the server, but it's meaningless and will be executed by the browser only (Client side again).
This is why you can use Razor variables to change the HTML and Javascript but not vice versa. Try to look at your page source code (CTRL+U in most browsers), there will be no sign of C# code there.
In short:
The server gets a request.
The server creates or "takes" the view, then computes and translates all the C# code that was embedded in the view to CSS, Javascript, and HTML.
The server returns the client side version of the view to the browser as a response to the request. (there is no C# at this point anymore)
the browser renders the page and executes all the Javascript
The Matlab Compiler is the standard way to do this. mcc
is the command. The Matlab Runtime is required to run the programs; I'm not sure if it can be directly integrated with the executable or not.
As a postgreSQL newbie I found the os x setup instructions on the postgresql site impenetrable. I got all kinds of errors. Fortunately the uninstaller worked fine.
cd /Library/PostgreSQL/11; open uninstall-postgresql.app/
Then I started over with a brew install followed by this article How to setup PostgreSQL on MacOS
It works fine now.
I have modified your code a little. Here's a working version (for me):
<select name="dd1" id="dd1">
<option value="none">None</option>
<option value="o1">option 1</option>
<option value="o2">option 2</option>
<option value="o3">option 3</option>
</select>
<div style="color:red;" id="msg_id"></div>
<script>
$('#everything').submit(function(e){
var department = $("#msg_id");
var msg = "Please select Department";
if ($('#dd1').val() == "") {
department.append(msg);
e.preventDefault();
return false;
}
});
</script>

As Alexander M. mentioned, you'll still have to use GParted, Partition Magic or a similar partition editor to grow your partition to the newly allocated physical drive. To do this just download the GParted iso, mount it as a bootable drive in the VirtualBox and boot from it.
I'm also reading an exported file which contains french and German languages. I used Encoding.GetEncoding("iso-8859-1"), true which worked out without any challenges.
for /f "tokens=* delims= " %%f in (myfile) do
This reads a file line-by-line, removing leading spaces (thanks, jeb).
set line=%%f
sets then the line
variable to the line just read and
call :procesToken
calls a subroutine that does something with the line
:processToken
is the start of the subroutine mentioned above.
for /f "tokens=1* delims=/" %%a in ("%line%") do
will then split the line at /
, but stopping tokenization after the first token.
echo Got one token: %%a
will output that first token and
set line=%%b
will set the line
variable to the rest of the line.
if not "%line%" == "" goto :processToken
And if line
isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.
You can use the minsize
and maxsize
to set a minimum & maximum size, for example:
def __init__(self,master):
master.minsize(width=666, height=666)
master.maxsize(width=666, height=666)
Will give your window a fixed width & height of 666 pixels.
Or, just using minsize
def __init__(self,master):
master.minsize(width=666, height=666)
Will make sure your window is always at least 666 pixels large, but the user can still expand the window.
You can only use Core Graphics (Quartz, 2D only) transforms directly applied to a UIView's transform property. To get the effects in coverflow, you'll have to use CATransform3D, which are applied in 3-D space, and so can give you the perspective view you want. You can only apply CATransform3Ds to layers, not views, so you're going to have to switch to layers for this.
Check out the "CovertFlow" sample that comes with Xcode. It's mac-only (ie not for iPhone), but a lot of the concepts transfer well.
The following will give you an array of the type you want while preserving type safety.
PCB[] getAll(Class<PCB[]> arrayType) {
PCB[] res = arrayType.cast(java.lang.reflect.Array.newInstance(arrayType.getComponentType(), list.size()));
for (int i = 0; i < res.length; i++) {
res[i] = list.get(i);
}
list.clear();
return res;
}
How this works is explained in depth in my answer to the question that Kirk Woll linked as a duplicate.
You can target that div from your stylesheet in a number of ways.
Simply use
.col-md-6:first-child {
background-color: blue;
}
Another way is to assign a class to one div and then apply the style to that class.
<div class="col-md-6 blue"></div>
.blue {
background-color: blue;
}
There are also inline styles.
<div class="col-md-6" style="background-color: blue"></div>
Your example code works fine to me. I'm not sure if I undestand what you intend to do, but if you want a blue background on the second div just remove the bg-primary
class from the section and add you custom class to the div.
.blue {_x000D_
background-color: blue;_x000D_
}
_x000D_

You could split the string on the whitespace and then re-add it, since you know its in between every one of the entries.
var string = "text to split";
string = string.split(" ");
var stringArray = new Array();
for(var i =0; i < string.length; i++){
stringArray.push(string[i]);
if(i != string.length-1){
stringArray.push(" ");
}
}
Update: Removed trailing space.
You may want to look into os dependent line separators, e.g.:
import os
with open('./output.txt', 'a') as f1:
f1.write(content + os.linesep)
I think the only way to do this is to run another machine in parallel and use that machine to issue commands to your android box similar to how you would with a phone. If you have issues with the IP changing you can reserve an ip on your router and have the machine grab that one instead of asking the routers DHCP for one. This way you can ping the machine and figure out if it's done rebooting to continue the script.
I am surprised no one mentioned hsearch/hcreate set of libraries which although is not available on windows, but is mandated by POSIX, and therefore available in Linux / GNU systems.
The link has a simple and complete basic example that very well explains its usage.
It even has thread safe variant, is easy to use and very performant.
Spring MVC runs on top of the Servlet API. So, you can use HttpServletRequest#getParameter()
for this:
String value1 = request.getParameter("value1");
String value2 = request.getParameter("value2");
The HttpServletRequest
should already be available to you inside Spring MVC as one of the method arguments of the handleRequest()
method.
This will work:
setItemBackgroundResource(android.R.color.holo_red_light)
I know this question is very old, but I was making similar thing in my kotlin app recently. So here is an example if anyone needs it:
val dfs = DecimalFormatSymbols.getInstance(Locale.getDefault())
val bigD = BigDecimal("1e+30")
val formattedBigD = DecimalFormat("#,##0.#",dfs).format(bigD)
Result displaying $formattedBigD:
1,000,000,000,000,000,000,000,000,000,000
your first try is using declarative pipelines, and the second working one is using scripted pipelines. you need to enclose steps in a steps declaration, and you can't use if
as a top-level step in declarative, so you need to wrap it in a script
step. here's a working declarative version:
pipeline {
agent any
stages {
stage('test') {
steps {
sh 'echo hello'
}
}
stage('test1') {
steps {
sh 'echo $TEST'
}
}
stage('test3') {
steps {
script {
if (env.BRANCH_NAME == 'master') {
echo 'I only execute on the master branch'
} else {
echo 'I execute elsewhere'
}
}
}
}
}
}
you can simplify this and potentially avoid the if statement (as long as you don't need the else) by using "when". See "when directive" at https://jenkins.io/doc/book/pipeline/syntax/. you can also validate jenkinsfiles using the jenkins rest api. it's super sweet. have fun with declarative pipelines in jenkins!

From a performance point of view, it doesn't matter in Python, and I'd assume the same for every modern language out there.
It really comes down to style and readability. Your second option (if-else block) is more readable than the first, and a lot more readable than the one-liner ternary operation.
If your code doesn't cross filesystem boundaries, i.e. you're just working with one filesystem, then use java.io.File.separator
.
This will, as explained, get you the default separator for your FS. As Bringer128 explained, System.getProperty("file.separator")
can be overriden via command line options and isn't as type safe as java.io.File.separator
.
The last one, java.nio.file.FileSystems.getDefault().getSeparator();
was introduced in Java 7, so you might as well ignore it for now if you want your code to be portable across older Java versions.
So, every one of these options is almost the same as others, but not quite. Choose one that suits your needs.
Here's one approach using a regular expression:
$string =~ s/^\s+|\s+$//g ; # remove both leading and trailing whitespace
Perl 6 will include a trim function:
$string .= trim;

If you want a shallow clone, you can do this with:
git clone -b mybranch --depth=1 https://example.com/myproject.git localname
--depth=1

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc
A set of simple examples:
Using Gson:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
public class Gson {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
com.google.gson.Gson gson = new com.google.gson.Gson();
Response respuesta = gson.fromJson(json, Response.class);
System.out.println(respuesta.getExample());
System.out.println(respuesta.getFr());
} catch (IOException ex) {
}
return null;
}
public class Response{
private String example;
private String fr;
public String getExample() {
return example;
}
public void setExample(String example) {
this.example = example;
}
public String getFr() {
return fr;
}
public void setFr(String fr) {
this.fr = fr;
}
}
}
Using json-simple:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
public class JsonSimple {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
try {
JSONParser parser = new JSONParser();
Object resultObject = parser.parse(json);
if (resultObject instanceof JSONArray) {
JSONArray array=(JSONArray)resultObject;
for (Object object : array) {
JSONObject obj =(JSONObject)object;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
}else if (resultObject instanceof JSONObject) {
JSONObject obj =(JSONObject)resultObject;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
} catch (Exception e) {
// TODO: handle exception
}
} catch (IOException ex) {
}
return null;
}
}
etc...
You can make a path for your file as bellow:
string path = "fileName-"+DateTime.Now.ToString("yyyy-dd-M--HH-mm-ss") + ".txt";
It's still not possible.
Here is an end to end solution I implemented for streaming Android microphone audio to a server for playback: Android AudioRecord to Server over UDP Playback Issues
I usually use:
$("#my-Select option[text='" + myText +"']").attr("selected","selected") ;
Yes:
RelativeLayout.LayoutParams params= new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.BELOW, R.id.below_id);
viewToLayout.setLayoutParams(params);
First, the code creates a new layout params by specifying the height and width. The addRule
method adds the equivalent of the xml properly android:layout_below
. Then you just call View#setLayoutParams
on the view you want to have those params.
$dateTime = new DateTime('now', new DateTimeZone('Asia/Kolkata'));
echo $dateTime->modify("+10 minutes")->format("H:i:s A");
In my case I need frames at least every second. I used the 'seek to' approach above but wondered if I could parallelize the task. I used the N processes with FIFO approach here: https://unix.stackexchange.com/questions/103920/parallelize-a-bash-for-loop/216475#216475
open_sem(){
mkfifo /tmp/pipe-$$
exec 3<>/tmp/pipe-$$
rm /tmp/pipe-$$
local i=$1
for((;i>0;i--)); do
printf %s 000 >&3
done
}
run_with_lock(){
local x
read -u 3 -n 3 x && ((0==x)) || exit $x
(
"$@"
printf '%.3d' $? >&3
)&
}
N=16
open_sem $N
time for i in {0..39} ; do run_with_lock ffmpeg -ss `echo $i` -i /tmp/input/GOPR1456.MP4 -frames:v 1 /tmp/output/period_down_$i.jpg & done
Essentially I forked the process with & but limited the number of concurrent threads to N.
This improved the 'seek to' approach from 26 seconds to 16 seconds in my case. The only problem is the main thread does not exit cleanly back to the terminal since stdout gets flooded.
"Centered content" can mean many different things, and Bootstrap centering has changed a lot since the original post.
Bootstrap 3
text-center
is used for display:inline
elementscenter-block
to center display:block
elementscol-*offset-*
to center grid columnsDemo Bootstrap 3 Horizontal Centering
Bootstrap 4
text-center
is still used for display:inline
elementsmx-auto
replaces center-block
to center display:block
elementsoffset-*
or mx-auto
can be used to center grid columnsjustify-content-center
in row
can also be used to center col-*
mx-auto
(auto x-axis margins) will center display:block
or display:flex
elements that have a defined width, (%
, vw
, px
, etc..). Flexbox is used by default on grid columns, so there are also various flexbox centering methods.
Demo Bootstrap 4 Horizontal Centering
Now that Bootstrap 4 is flexbox by default there are many different approaches to vertical alignment using: auto-margins, flexbox utils, or the display utils along with vertical align utils. At first "vertical align utils" seems obvious but these only work with inline and table display elements. Here are some Bootstrap 4 vertical centering options..
1 - Vertical Center Using Auto Margins:
Another way to vertically center is to use my-auto
. This will center the element within it's container. For example, h-100
makes the row full height, and my-auto
will vertically center the col-sm-12
column.
<div class="row h-100">
<div class="col-sm-12 my-auto">
<div class="card card-block w-25">Card</div>
</div>
</div>
Vertical Center Using Auto Margins Demo
my-auto
represents margins on the vertical y-axis and is equivalent to:
margin-top: auto;
margin-bottom: auto;
2 - Vertical Center with Flexbox:
Since Bootstrap 4 .row
is now display:flex
you can simply use align-self-center
on any column to vertically center it...
<div class="row">
<div class="col-6 align-self-center">
<div class="card card-block">
Center
</div>
</div>
<div class="col-6">
<div class="card card-inverse card-danger">
Taller
</div>
</div>
</div>
or, use align-items-center
on the entire .row
to vertically center align all col-*
in the row...
<div class="row align-items-center">
<div class="col-6">
<div class="card card-block">
Center
</div>
</div>
<div class="col-6">
<div class="card card-inverse card-danger">
Taller
</div>
</div>
</div>
Vertical Center Different Height Columns Demo
3 - Vertical Center Using Display Utils:
Bootstrap 4 has display utils that can be used for display:table
, display:table-cell
, display:inline
, etc.. These can be used with the vertical alignment utils to align inline, inline-block or table cell elements.
<div class="row h-50">
<div class="col-sm-12 h-100 d-table">
<div class="card card-block d-table-cell align-middle">
I am centered vertically
</div>
</div>
</div>
Position the cursor inside the class, then press ALT + Ins and select Getters and Setters
from the contextual menu.
You could use super(ChildClass, self).__init__()
class BaseClass(object):
def __init__(self, *args, **kwargs):
pass
class ChildClass(BaseClass):
def __init__(self, *args, **kwargs):
super(ChildClass, self).__init__(*args, **kwargs)
Your indentation is incorrect, here's the modified code:
class Car(object):
condition = "new"
def __init__(self, model, color, mpg):
self.model = model
self.color = color
self.mpg = mpg
class ElectricCar(Car):
def __init__(self, battery_type, model, color, mpg):
self.battery_type=battery_type
super(ElectricCar, self).__init__(model, color, mpg)
car = ElectricCar('battery', 'ford', 'golden', 10)
print car.__dict__
Here's the output:
{'color': 'golden', 'mpg': 10, 'model': 'ford', 'battery_type': 'battery'}
According to ng-repeat docs http://docs.angularjs.org/api/ng.directive:ngRepeat, you can store the key or array index in the variable of your choice. (indexVar, valueVar) in values
so you can write
<div ng-repeat="(fIndex, f) in foos">
<div>
<div ng-repeat="b in foos.bars">
<a ng-click="addSomething(fIndex)">Add Something</a>
</div>
</div>
</div>
One level up is still quite clean with $parent.$index but several parents up, things can get messy.
Note: $index
will continue to be defined at each scope, it is not replaced by fIndex
.
This should do what you want, but without more context I can't tell for sure.
Writing $text to a file:
$text = "Anything";
$var_str = var_export($text, true);
$var = "<?php\n\n\$text = $var_str;\n\n?>";
file_put_contents('filename.php', $var);
Retrieving it again:
include 'filename.php';
echo $text;
And for yet another option, I'd go with awk!
echo "foo bar <foo> bla 1 2 3.4" | awk '{ print $(NF-1), $NF; }'
This will split the input (I'm using STDIN here, but your input could easily be a file) on spaces, and then print out the last-but-one field, and then the last field. The $NF
variables hold the number of fields found after exploding on spaces.
The benefit of this is that it doesn't matter if what precedes the last two fields changes, as long as you only ever want the last two it'll continue to work.
Note that if a view is non-clickable (a TextView for example), setting setOnClickListener(null)
will mean the view is clickable. Use mMyView.setClickable(false)
if you don't want your view to be clickable. For example, if you use a xml drawable for the background, which shows different colours for different states, if your view is still clickable, users can click on it and the different background colour will show, which may look weird.
Division of two numbers using bitwise operators.
#include <stdio.h>
int remainder, divisor;
int division(int tempdividend, int tempdivisor) {
int quotient = 1;
if (tempdivisor == tempdividend) {
remainder = 0;
return 1;
} else if (tempdividend < tempdivisor) {
remainder = tempdividend;
return 0;
}
do{
tempdivisor = tempdivisor << 1;
quotient = quotient << 1;
} while (tempdivisor <= tempdividend);
/* Call division recursively */
quotient = quotient + division(tempdividend - tempdivisor, divisor);
return quotient;
}
int main() {
int dividend;
printf ("\nEnter the Dividend: ");
scanf("%d", ÷nd);
printf("\nEnter the Divisor: ");
scanf("%d", &divisor);
printf("\n%d / %d: quotient = %d", dividend, divisor, division(dividend, divisor));
printf("\n%d / %d: remainder = %d", dividend, divisor, remainder);
getch();
}
What you need is called attribute selector. An example, using your html structure, is the following:
div[class^="tocolor-"], div[class*=" tocolor-"] {
color:red
}
In the place of div
you can add any element or remove it altogether, and in the place of class
you can add any attribute of the specified element.
[class^="tocolor-"]
— starts with "tocolor-".
[class*=" tocolor-"]
— contains the substring "tocolor-" occurring directly after a space character.
Demo: http://jsfiddle.net/K3693/1/
More information on CSS attribute selectors, you can find here and here. And from MDN Docs MDN Docs

You must set app:elevation="0dp"
in the android.support.design.widget.AppBarLayout
and then it works.

android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"

Depending on what I'm using it for, or if I'm doing something that others will use, I typically just input("Do eighteen backflips to continue")
if it's just for me, if others will be using I just create a batch file and pause it after
cd '/file/path/here'
python yourfile.py
pause
I use the above if there is going to be files renamed, moved, copied, etc. and my cmd needs to be in the particular folder for things to fall where I want them, otherwise - just
python '/path/to/file/yourfile.py'
pause
Are you sure you're not confusing Oracle database with Oracle SQL Developer?
The database itself has no date format, the date comes out of the database in raw form. It's up to the client software to render it, and SQL Developer does use YYYY-MM-DD as its default format, which is next to useless, I agree.
edit: As was commented below, SQL Developer can be reconfigured to display DATE values properly, it just has bad defaults.
If your database is PostgreSQL and you have php7.2 you should run the following commands:
sudo apt-get install php7.2-pgsql
and
php artisan migrate
Perhaps you need to read about interactive usage of Matplotlib. However, if you are going to build an app, you should be using the API and embedding the figures in the windows of your chosen GUI toolkit (see examples/embedding_in_tk.py
, etc).
Can't you get a free version of Visual Studio Student Addition from your school? Most Universities have programs to give free software to students.
If you want the entire package name with it, call:
String name = MyClass.class.getCanonicalName();
If you only want the last element, call:
String name = MyClass.class.getSimpleName();
Unless the variable k
is defined, that's probably what's causing your trouble. Something like this will do what you want:
var new_tweets = { };
new_tweets.k = { };
new_tweets.k.tweet_id = 98745521;
new_tweets.k.user_id = 54875;
new_tweets.k.data = { };
new_tweets.k.data.in_reply_to_screen_name = 'other_user';
new_tweets.k.data.text = 'tweet text';
// Will create the JSON string you're looking for.
var json = JSON.stringify(new_tweets);
You can also do it all at once:
var new_tweets = {
k: {
tweet_id: 98745521,
user_id: 54875,
data: {
in_reply_to_screen_name: 'other_user',
text: 'tweet_text'
}
}
}
I'm blind and from some months I'm using VINUX (a linux distro based on Ubuntu) with SODBEANS (a version of netbeans with a plug-in named SAPPY that add a TTS support). This solution works quite well but sometimes I prefer to launch Win XP and NVDA for launching many pages on FireFox because Vinux doesn't work very well when you try to open more than 3 windows of FireFox...
If you guys are facing "Permission Denial: starting Intent..." error or if the app is getting crash without any reason during launching the app - Then use this single line code in Manifest
android:exported="true"
Please be careful with finish(); , if you missed out it the app getting frozen. if its mentioned the app would be a smooth launcher.
finish();
The other solution only works for two activities that are in the same application. In my case, application B doesn't know class com.example.MyExampleActivity.class
in the code, so compile will fail.
I searched on the web and found something like this below, and it works well.
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.example", "com.example.MyExampleActivity"));
startActivity(intent);
You can also use the setClassName method:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.hotfoot.rapid.adani.wheeler.android", "com.hotfoot.rapid.adani.wheeler.android.view.activities.MainActivity");
startActivity(intent);
finish();
You can also pass the values from one app to another app :
Intent launchIntent = getApplicationContext().getPackageManager().getLaunchIntentForPackage("com.hotfoot.rapid.adani.wheeler.android.LoginActivity");
if (launchIntent != null) {
launchIntent.putExtra("AppID", "MY-CHILD-APP1");
launchIntent.putExtra("UserID", "MY-APP");
launchIntent.putExtra("Password", "MY-PASSWORD");
startActivity(launchIntent);
finish();
} else {
Toast.makeText(getApplicationContext(), " launch Intent not available", Toast.LENGTH_SHORT).show();
}
db.adminCommand( { getLog: "*" } )
Then
db.adminCommand( { getLog : "global" } )
datas.Where((data, index) =>
{
//Your Logic
return false;
}).Any();
In some simple case,my way is using where + false + any
.
It is fater a little than foreach + select((data,index)=>new{data,index})
,and without custom Foreach method.
MyLogic:
- use statement body run your logic.
- because return false,new Enumrable data count is zero.
- use Any() let yeild run.

You can use QString.arg like this
QString my_formatted_string = QString("%1/%2-%3.txt").arg("~", "Tom", "Jane");
// You get "~/Tom-Jane.txt"
This method is preferred over sprintf because:
Changing the position of the string without having to change the ordering of substitution, e.g.
// To get "~/Jane-Tom.txt"
QString my_formatted_string = QString("%1/%3-%2.txt").arg("~", "Tom", "Jane");
Or, changing the type of the arguments doesn't require changing the format string, e.g.
// To get "~/Tom-1.txt"
QString my_formatted_string = QString("%1/%2-%3.txt").arg("~", "Tom", QString::number(1));
As you can see, the change is minimal. Of course, you generally do not need to care about the type that is passed into QString::arg() since most types are correctly overloaded.
One drawback though: QString::arg() doesn't handle std::string. You will need to call: QString::fromStdString() on your std::string to make it into a QString before passing it to QString::arg(). Try to separate the classes that use QString from the classes that use std::string. Or if you can, switch to QString altogether.

To calculate the mean, loop through the list/array of numbers, keeping track of the partial sums and the length. Then return the sum/length
.
double sum = 0.0;
int length = 0;
for( double number : numbers ) {
sum += number;
length++;
}
return sum/length;
Variance is calculated similarly. Standard deviation is simply the square root of the variance:
double stddev = Math.sqrt( variance );
I am doing something very similar. I'm just getting into coding, so this may not be the most efficient way of doing it, but this is how I did it:
@ECHO OFF
ECHO HELLO
ping localhost -n 1 >nul
cls
color 01
ECHO HELLO
ping localhost -n 1 >nul
cls
color 02
ECHO HELLO
and so one and so forth.
You normally use a tool like pip
to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.
For this to work, you do need to install the wheel
package:
pip install wheel
You can then tell pip
to install the project (and it'll download the wheel if available), or the wheel file directly:
pip install project_name # discover, download and install
pip install wheel_file.whl # directly install the wheel
The wheel
module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:
python -m wheel install wheel_file.whl
Also see the wheel
project documentation.
Since you need to set ?enablejsapi=true
in the src of the iframe before you can use the playVideo
/ pauseVideo
commands mentioned in other answers, it might be useful to add this programmatically via Javascript (especially if, eg. you want this behaviour to apply to videos embedded by other users who have just cut and paste a YouTube embed code). In that case, something like this might be useful:
function initVideos() {
// Find all video iframes on the page:
var iframes = $(".video").find("iframe");
// For each of them:
for (var i = 0; i < iframes.length; i++) {
// If "enablejsapi" is not set on the iframe's src, set it:
if (iframes[i].src.indexOf("enablejsapi") === -1) {
// ...check whether there is already a query string or not:
// (ie. whether to prefix "enablejsapi" with a "?" or an "&")
var prefix = (iframes[i].src.indexOf("?") === -1) ? "?" : "&";
iframes[i].src += prefix + "enablejsapi=true";
}
}
}
...if you call this on document.ready
then all iframes in a div with a class of "video" will have enablejsapi=true
added to their source, which allows the playVideo / pauseVideo commands to work on them.
(nb. this example uses jQuery for that one line that sets var iframes
, but the general approach should work just as well with pure Javascript if you're not using jQuery).
You need to use the __getitem__
method.
class MyClass:
def __getitem__(self, key):
return key * 2
myobj = MyClass()
myobj[3] #Output: 6
And if you're going to be setting values you'll need to implement the __setitem__
method too, otherwise this will happen:
>>> myobj[5] = 1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: MyClass instance has no attribute '__setitem__'
Use this syntax to delete the rows also to redirect to the homepage (To avoid page load errors) :

"Visual Studio does not support std::cout as debug tool for non-console applications"

Enter code here sometimes in popups it would not work to binding just a form and passing the onSubmit to the form because form may not have any input.
In this case if you bind the event to the document by doing document.addEventListener
it will cause problem in another parts of the application.
For solving this issue we should wrap a form and should put a input with what is hidden by css, then you focus on that input by ref it will be work correctly.

First, pressing Enter inside a textarea does not submit the form unless you have script to make it do that. That's the behaviour the user expects and I'd recommend against changing it. However, if you must do this, the easiest approach would be to find the script that is making Enter submit the form and change it. The code will have something like
if (evt.keyCode == 13) {
form.submit();
}
... and you could just change it to
if (evt.keyCode == 13 && !evt.shiftKey) {
form.submit();
}
On the other hand, if you don't have access to this code for some reason, you need to do the following to make it work in all major browsers even if the caret is not at the end of the text:

el.value = val.slice(0, selStart) + text + val.slice(el.selectionEnd);
el.selectionEnd = el.selectionStart = selStart + text.length;
} else if (typeof document.selection != "undefined") {
var textRange = document.selection.createRange();
textRange.text = text;
textRange.collapse(false);

CSS transitions only animate from one set of styles to another; what you're looking for is CSS animations.
You need to define the animation keyframes and apply it to the element:
@keyframes changewidth {
from {
width: 100px;
}
to {
width: 300px;
}
}
div {
animation-duration: 0.1s;
animation-name: changewidth;
animation-iteration-count: infinite;
animation-direction: alternate;
}

Bit rate is a measure of the number of data bits (that's 0's and 1's) transmitted in one second. A figure of 2400 bits per second means 2400 zeros or ones can be transmitted in one second, hence the abbreviation 'bps'.
Baud rate by definition means the number of times a signal in a communications channel changes state. For example, a 2400 baud rate means that the channel can change states up to 2400 times per second. When I say 'change state' I mean that it can change from 0 to 1 up to 2400 times per second. If you think about this, it's pretty much similar to the bit rate, which in the above example was 2400 bps.
Whether you can transmit 2400 zeros or ones in one second (bit rate), or change the state of a digital signal up to 2400 times per second (baud rate), it the same thing.
In case you have multiple images and you want to loop though them and show them 1 by 1 along with titles - this is what you can do. No need to explicitly define ax1, ax2, etc.

for i in range(len(ax)):
for j in range(len(ax[i])):
## ax[i,j].imshow(test_images_gr[0].reshape(28,28))
ax[i,j].set_title('Title-' + str(i) + str(j))
I got similar error (org.aspectj.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 15) while using aspectj 1.8.13.

in this scenario:
DELETE FROM tableA
WHERE (SELECT q.entitynum
FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum)
WHERE (LENGTH(q.memotext) NOT IN (8,9,10)
OR q.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date'));
aren't you missing the column you want to compare to? example:
DELETE FROM tableA
WHERE entitynum in (SELECT q.entitynum
FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum)
WHERE (LENGTH(q.memotext) NOT IN (8,9,10)
OR q.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date'));
I assume it's that column since in your select statement you're selecting from the same table you're wanting to delete from with that column.
Especially for non-UTC timezones:
The only timezone that has its own method is timezone.utc
, but you can fudge a timezone with any UTC offset if you need to by using timedelta
& timezone
, and forcing it using .replace
.
In [1]: from datetime import datetime, timezone, timedelta
In [2]: def force_timezone(dt, utc_offset=0):
...: return dt.replace(tzinfo=timezone(timedelta(hours=utc_offset)))
...:
In [3]: dt = datetime(2011,8,15,8,15,12,0)
In [4]: str(dt)
Out[4]: '2011-08-15 08:15:12'
In [5]: str(force_timezone(dt, -8))
Out[5]: '2011-08-15 08:15:12-08:00'
Using timezone(timedelta(hours=n))
as the time zone is the real silver bullet here, and it has lots of other useful applications.
i think this can be as simple
let as assume that you are going to pass multiple parameters to you action as you read up there actions accept only two parameters context
and payload
which is your data you want to pass in action so let take an example
Setting up Action
instead of
actions: {
authenticate: ({ commit }, token, expiration) => commit('authenticate', token, expiration)
}
do
actions: {
authenticate: ({ commit }, {token, expiration}) => commit('authenticate', token, expiration)
}
Calling (dispatching) Action
instead of
this.$store.dispatch({
type: 'authenticate',
token: response.body.access_token,
expiration: response.body.expires_in + Date.now()
})
do
this.$store.dispatch('authenticate',{
token: response.body.access_token,
expiration: response.body.expires_in + Date.now()
})
hope this gonna help

How about just sort
.
sort -t, -nk3 user.csv
where
-t,
- defines your delimiter as ,
.
-n
- gives you numerical sort. Added since you added it in your
attempt. If your user field is text only then you dont need it.
-k3
- defines the field (key). user is the third field.
I would try to avoid changing the xticklabels
if possible, otherwise it can get very confusing if you for example overplot your histogram with additional data.
Defining the range of your grid is probably the best and with imshow
it can be done by adding the extent
keyword. This way the axes gets adjusted automatically. If you want to change the labels i would use set_xticks
with perhaps some formatter. Altering the labels directly should be the last resort.
fig, ax = plt.subplots(figsize=(6,6))
ax.imshow(hist, cmap=plt.cm.Reds, interpolation='none', extent=[80,120,32,0])
ax.set_aspect(2) # you may also use am.imshow(..., aspect="auto") to restore the aspect ratio
The .bashrc file is in your user home directory (~/.bashrc or ~vagrant/.bashrc both resolve to the same path), inside the VM's filesystem. This file is invisible on the host machine, so you can't use any Windows editors to edit it directly.
You have two simple choices:
Learn how to use a console-based text editor. My favourite is vi (or vim), which takes 15 minutes to learn the basics and is much quicker for simple edits than anything else.
vi .bashrc
Copy .bashrc out to /vagrant (which is a shared directory) and edit it using your Windows editors. Make sure not to save it back with any extensions.
cp .bashrc /vagrant ... edit using your host machine ... cp /vagrant/.bashrc .
I'd recommend getting to know the command-line based editors. Once you're working inside the VM, it's best to stay there as otherwise you might just get confused.
You (the vagrant user) are the owner of your home .bashrc so you do have permissions to edit it.
Once edited, you can execute it by typing source .bashrc I prefer to logout and in again (there may be more than one file executed on login).
EDIT: Okay, so you don't want your local time (which isn't Australia) to contribute to the result, but instead the Australian time zone. Your existing code should be absolutely fine then, although Sydney is currently UTC+11, not UTC+10.. Short but complete test app:
import java.util.*;
import java.text.*;
public class Test {
public static void main(String[] args) throws InterruptedException {
Date date = new Date(1318386508000L);
DateFormat format = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
format.setTimeZone(TimeZone.getTimeZone("Etc/UTC"));
String formatted = format.format(date);
System.out.println(formatted);
format.setTimeZone(TimeZone.getTimeZone("Australia/Sydney"));
formatted = format.format(date);
System.out.println(formatted);
}
}
Output:
12/10/2011 02:28:28
12/10/2011 13:28:28
I would also suggest you start using Joda Time which is simply a much nicer date/time API...
EDIT: Note that if your system doesn't know about the Australia/Sydney
time zone, it would show UTC. For example, if I change the code about to use TimeZone.getTimeZone("blah/blah")
it will show the UTC value twice. I suggest you print TimeZone.getTimeZone("Australia/Sydney").getDisplayName()
and see what it says... and check your code for typos too :)
You can try to search in preferences (android studio IDE > preferences). In aptana studio it works like this making smaller: CMD and -, use CMD shift and =. Works?
I think you're getting confused about what can hold what in JSON.Net.
JToken
is a generic representation of a JSON value of any kind. It could be a string, object, array, property, etc.JProperty
is a single JToken
value paired with a name. It can only be added to a JObject
, and its value cannot be another JProperty
.JObject
is a collection of JProperties
. It cannot hold any other kind of JToken
directly.In your code, you are attempting to add a JObject
(the one containing the "banana" data) to a JProperty
("orange") which already has a value (a JObject
containing {"colour":"orange","size":"large"}
). As you saw, this will result in an error.
What you really want to do is add a JProperty
called "banana" to the JObject
which contains the other fruit JProperties
. Here is the revised code:
JObject foodJsonObj = JObject.Parse(jsonText);
JObject fruits = foodJsonObj["food"]["fruit"] as JObject;
fruits.Add("banana", JObject.Parse(@"{""colour"":""yellow"",""size"":""medium""}"));
you can do it via normal JS also
var url = document.URL
var newAdditionalURL = "";
var tempArray = url.split("?");
var baseURL = tempArray[0];
var aditionalURL = tempArray[1];
var temp = "";
if(aditionalURL)
{
var tempArray = aditionalURL.split("&");
for ( var i in tempArray ){
if(tempArray[i].indexOf("rows") == -1){
newAdditionalURL += temp+tempArray[i];
temp = "&";
}
}
}
var rows_txt = temp+"rows=10";
var finalURL = baseURL+"?"+newAdditionalURL+rows_txt;
Try to avoid globals, instead you can use something like this
class myClass() {
private $myNumber;
public function setNumber($number) {
$this->myNumber = $number;
}
}
Now you can call
$class = new myClass();
$class->setNumber('1234');
Interfaces and abstracted classes seem very similar, however, there are important differences between them.
Abstraction is based on a good "is-a" relationship. Meaning that you would say that a car is a Honda, and a Honda is a car. Using abstraction on a class means you can also have abstract methods. This would require any subclass extended from it to obtain the abstract methods and override them. Using the example below, we can create an abstract howToStart(); method that will require each class to implement it.
Through abstraction, we can provide similarities between code so we would still have a base class. Using an example of the Car class idea we could create:
public abstract class Car{
private String make;
private String model
protected Car() { } // Default constructor
protect Car(String make, String model){
//Assign values to
}
public abstract void howToStart();
}
Then with the Honda class we would have:
public class Honda extends implements Engine {
public Honda() { } // Default constructor
public Honda(String make, String model){
//Assign values
}
@Override
public static void howToStart(){
// Code on how to start
}
}
Interfaces are based on the "has-a" relationship. This would mean you could say a car has-a engine, but an engine is not a car. In the above example, Honda has implements Engine
.
For the engine interface we could create:
public interface Engine {
public void startup();
}
The interface will provide a many-to-one instance. So we could apply the Engine interface to any type of car. We can also extend it to other object. Like if we were to make a boat class, and have sub classes of boat types, we could extend Engine and have the sub classes of boat require the startup();
method. Interfaces are good for creating framework to various classes that have some similarities. We can also implement multiple instances in one class, such as:
public class Honda extends implements Engine, Transmission, List<Parts>
Hopefully this helps.

Most of the time that I use AsyncTask my business logic is on a separated business class instead of being on the UI. In that case, I couldn't have a loop at doInBackground(). An example would be a synchronization process that consumes services and persist data one after another.
I end up handing on my task to the business object so it can handle cancelation. My setup is like this:
public abstract class MyActivity extends Activity {
private Task mTask;
private Business mBusiness;
public void startTask() {
if (mTask != null) {
mTask.cancel(true);
}
mTask = new mTask();
mTask.execute();
}
}
protected class Task extends AsyncTask<Void, Void, Boolean> {
@Override
protected void onCancelled() {
super.onCancelled();
mTask.cancel(true);
// ask if user wants to try again
}
@Override
protected Boolean doInBackground(Void... params) {
return mBusiness.synchronize(this);
}
@Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
mTask = null;
if (result) {
// done!
}
else {
// ask if user wants to try again
}
}
}
public class Business {
public boolean synchronize(AsyncTask<?, ?, ?> task) {
boolean response = false;
response = loadStuff(task);
if (response)
response = loadMoreStuff(task);
return response;
}
private boolean loadStuff(AsyncTask<?, ?, ?> task) {
if (task != null && task.isCancelled()) return false;
// load stuff
return true;
}
}
You have to reference System.Configuration

Yes, you can use the shorthand syntax for if

rate = lambda(t): (200 * exp(-t)) if t > 200 else (400 * exp(-t))
Note that you don't use explicit return
statements inlambda
s either.
You can use boolean indexing
:
df = pd.DataFrame({'Sales':[10,20,30,40,50], 'A':[3,4,7,6,1]})
print (df)
A Sales

1 4 20

s = 30
df1 = df[df['Sales'] >= s]
print (df1)

4 1 50
df2 = df[df['Sales'] < s]
print (df2)
A Sales

i created this for my script I use in my work for eyebeam.
:CREATES A CHECK VARIABLE
set lookup=0
:CHECKS IF THE FOLDER ALREADY EXIST"
IF EXIST "%UserProfile%\AppData\Local\CounterPath\RegNow Enhanced\default_user\" (set lookup=1)
:IF CHECK is still 0 which means does not exist. It creates the folder
IF %lookup%==0 START "" mkdir "%UserProfile%\AppData\Local\CounterPath\RegNow Enhanced\default_user\"
Building upon the answer from booij boy, check if you checked the "windows authentication" feature in Control Panel -> Programs -> Turn windows features on or of -> Internet Information Services -> World Wide Web Services -> Security
Also, there seems to be a big difference when using firefox or internet explorer. After enabeling the "windows authentication" it works for me but only in IE.
Here are three possibilities:
foo = """
this is
a multi-line string.
"""
def f1(foo=foo): return iter(foo.splitlines())
def f2(foo=foo):
retval = ''
for char in foo:
retval += char if not char == '\n' else ''
if char == '\n':
yield retval
retval = ''
if retval:
yield retval
def f3(foo=foo):
prevnl = -1
while True:
nextnl = foo.find('\n', prevnl + 1)
if nextnl < 0: break
yield foo[prevnl + 1:nextnl]
prevnl = nextnl
if __name__ == '__main__':
for f in f1, f2, f3:
print list(f())
Running this as the main script confirms the three functions are equivalent. With timeit
(and a * 100
for foo
to get substantial strings for more precise measurement):
$ python -mtimeit -s'import asp' 'list(asp.f3())'
1000 loops, best of 3: 370 usec per loop
$ python -mtimeit -s'import asp' 'list(asp.f2())'
1000 loops, best of 3: 1.36 msec per loop
$ python -mtimeit -s'import asp' 'list(asp.f1())'
10000 loops, best of 3: 61.5 usec per loop
Note we need the list()
call to ensure the iterators are traversed, not just built.
IOW, the naive implementation is so much faster it isn't even funny: 6 times faster than my attempt with find
calls, which in turn is 4 times faster than a lower-level approach.
Lessons to retain: measurement is always a good thing (but must be accurate); string methods like splitlines
are implemented in very fast ways; putting strings together by programming at a very low level (esp. by loops of +=
of very small pieces) can be quite slow.
Edit: added @Jacob's proposal, slightly modified to give the same results as the others (trailing blanks on a line are kept), i.e.:
from cStringIO import StringIO
def f4(foo=foo):
stri = StringIO(foo)
while True:
nl = stri.readline()
if nl != '':
yield nl.strip('\n')
else:
raise StopIteration
Measuring gives:
$ python -mtimeit -s'import asp' 'list(asp.f4())'
1000 loops, best of 3: 406 usec per loop
not quite as good as the .find
based approach -- still, worth keeping in mind because it might be less prone to small off-by-one bugs (any loop where you see occurrences of +1 and -1, like my f3
above, should automatically trigger off-by-one suspicions -- and so should many loops which lack such tweaks and should have them -- though I believe my code is also right since I was able to check its output with other functions').
But the split-based approach still rules.
An aside: possibly better style for f4
would be:
from cStringIO import StringIO
def f4(foo=foo):
stri = StringIO(foo)
while True:
nl = stri.readline()
if nl == '': break
yield nl.strip('\n')
at least, it's a bit less verbose. The need to strip trailing \n
s unfortunately prohibits the clearer and faster replacement of the while
loop with return iter(stri)
(the iter
part whereof is redundant in modern versions of Python, I believe since 2.3 or 2.4, but it's also innocuous). Maybe worth trying, also:
return itertools.imap(lambda s: s.strip('\n'), stri)
or variations thereof -- but I'm stopping here since it's pretty much a theoretical exercise wrt the strip
based, simplest and fastest, one.
I've created a JUnit Test class(as a additional knowledge/info) for the same issue. Hope you'll be finding this helpful.
public class StringHelper {
//Separate words from String which has gigits
public String drawDigitsFromString(String strValue){
String str = strValue.trim();
String digits="";
for (int i = 0; i < str.length(); i++) {
char chrs = str.charAt(i);
if (Character.isDigit(chrs))
digits = digits+chrs;
}
return digits;
}
}
And JUnit Test case is:
public class StringHelperTest {
StringHelper helper;
@Before
public void before(){
helper = new StringHelper();
}
@Test
public void testDrawDigitsFromString(){
assertEquals("187111", helper.drawDigitsFromString("TCS187TCS111"));
}
}
It's not a query waiting for connection; it's a connection pointer waiting for the timeout to terminate.
It doesn't have an impact on performance. The only thing it's using is a few bytes as every connection does.
The really worst case: It's using one connection of your pool; If you would connect multiple times via console client and just close the client without closing the connection, you could use up all your connections and have to wait for the timeout to be able to connect again... but this is highly unlikely :-)
See MySql Proccesslist filled with "Sleep" Entries leading to "Too many Connections"? and https://dba.stackexchange.com/questions/1558/how-long-is-too-long-for-mysql-connections-to-sleep for more information.
You could do something like this:
$("span, p").each(function() {
var text = $(this).text();
text = text.replace("lollypops", "marshmellows");
$(this).text(text);
});
It will be better to mark all tags with text that needs to be examined with a suitable class name.
Also, this may have performance issues. jQuery or javascript in general aren't really suitable for this kind of operations. You are better off doing it server side.
import datetime
timestamp = datetime.datetime.fromtimestamp(1500000000)
print(timestamp.strftime('%Y-%m-%d %H:%M:%S'))
This will give the output:
2017-07-14 08:10:00
Since you're using Tortoise you may want to check out this link on LosTechies. It should be almost exactly what you are looking for.
Yes, it is true that Abstraction and Encapsulation are about hiding.
Using only relevant details and hiding unnecessary data at Design Level is called Abstraction. (Like selecting only relevant properties for a class 'Car' to make it more abstract or general.)
Encapsulation is the hiding of data at Implementation Level. Like how to actually hide data from direct/external access. This is done by binding data and methods to a single entity/unit to prevent external access. Thus, encapsulation is also known as data hiding at implementation level.
Use the .Replace() method
Line.Replace("\n", "whatever you want to replace with");
Thanks for @bkurzius's answer and this update is for Charles 3.10+. (The reason is here)
Install Charles Root Certificate on a Mobile Device or Remote Browser...
, and just follow the instruction. (use the Android's browser to download and install the certificate.)If you use jQuery built-in after()
with empty value it will create a dynamic object that will match your :after
CSS selector.
$('.active').after().click(function () {
alert('clickable!');
});
See the jQuery documentation.
You could use a javax.swing.ImageIcon and add it to a JLabel using setIcon() method, then add the JLabel to the JPanel.
Here's a simple function I wrote to display tabular data without having to input each column name: (Also, be aware: Nested looping)
function display_data($data) {
$output = '<table>';
foreach($data as $key => $var) {
$output .= '<tr>';
foreach($var as $k => $v) {
if ($key === 0) {
$output .= '<td><strong>' . $k . '</strong></td>';
} else {
$output .= '<td>' . $v . '</td>';
}
}
$output .= '</tr>';
}
$output .= '</table>';
echo $output;
}
Hi Jack,
your function design is fine, but this function always misses the first dataset in the array. I tested that.
Your function is so fine, that many people will use it, but they will always miss the first dataset. That is why I wrote this amendment.
The missing dataset results from the condition if key === 0. If key = 0 only the columnheaders are written, but not the data which contains $key 0 too. So there is always missing the first dataset of the array.
You can avoid that by moving the if condition above the second foreach loop like this:
function display_data($data) {
$output = "<table>";
foreach($data as $key => $var) {
//$output .= '<tr>';
if($key===0) {
$output .= '<tr>';
foreach($var as $col => $val) {
$output .= "<td>" . $col . '</td>';
}
$output .= '</tr>';
foreach($var as $col => $val) {
$output .= '<td>' . $val . '</td>';
}
$output .= '</tr>';
}
else {
$output .= '<tr>';
foreach($var as $col => $val) {
$output .= '<td>' . $val . '</td>';
}
$output .= '</tr>';
}
}
$output .= '</table>';
echo $output;
}
Best regards and thanks - Axel Arnold Bangert - Herzogenrath 2016
and another update that removes redundant code blocks that hurt maintainability of the code.
function display_data($data) {
$output = '<table>';
foreach($data as $key => $var) {
$output .= '<tr>';
foreach($var as $k => $v) {
if ($key === 0) {
$output .= '<td><strong>' . $k . '</strong></td>';
} else {
$output .= '<td>' . $v . '</td>';
}
}
$output .= '</tr>';
}
$output .= '</table>';
echo $output;
}
You can use display: flex
and height: 100vh
html, body {_x000D_
height: 100%;_x000D_
margin: 0px;_x000D_
}_x000D_
body {_x000D_
display: flex;_x000D_
}_x000D_
_x000D_
.left, .right {_x000D_
flex: 1;_x000D_
}_x000D_
_x000D_
.left {_x000D_
background: orange;_x000D_
}_x000D_
_x000D_
.right {_x000D_
background: cyan;_x000D_
}
_x000D_
<div class="left">left</div>_x000D_
<div class="right">right</div>
_x000D_
The following automatically uses the best precision:
/**
* Compare to floats for (almost) equality. Will check whether they are
* at most 5 ULP apart.
*/
public static boolean isFloatingEqual(float v1, float v2) {
if (v1 == v2)
return true;
float absoluteDifference = Math.abs(v1 - v2);
float maxUlp = Math.max(Math.ulp(v1), Math.ulp(v2));
return absoluteDifference < 5 * maxUlp;
}
Of course, you might choose more or less than 5 ULPs (‘unit in the last place’).
If you’re into the Apache Commons library, the Precision
class has compareTo()
and equals()
with both epsilon and ULP.
I believe you can do this:
gem "foo", path: "/path/to/foo"
This is another late answer but i figured out a fairly simple way of placing the "bar" text in between the four squares. Here are the changes i made; In the bar section i wrapped the "bar" text within a center and div tags.
<header><center><div class="bar">bar</div></center></header>
And in the CSS section i created a "bar" class which is used in the div tag above. After adding this the bar text was centered between the four colored blocks.
.bar{
position: relative;
}
JsonResult result = Json(r);
result.MaxJsonLength = Int32.MaxValue;
result.JsonRequestBehavior = JsonRequestBehavior.AllowGet;
return result;
To start with, I do not suggest using "*" in regexes. Yes, I know, it is the most used multi-character delimiter, but it is nevertheless a bad idea. This is because, while it does match any amount of repetition for that character, "any" includes 0, which is usually something you want to throw a syntax error for, not accept. Instead, I suggest using the +
sign, which matches any repetition of length > 1. What's more, from what I can see, you are dealing with fixed-length parenthesized expressions. As a result, you can probably use the {x, y}
syntax to specifically specify the desired length.
However, if you really do need non-greedy repetition, I suggest consulting the all-powerful ?
. This, when placed after at the end of any regex repetition specifier, will force that part of the regex to find the least amount of text possible.
That being said, I would be very careful with the ?
as it, like the Sonic Screwdriver in Dr. Who, has a tendency to do, how should I put it, "slightly" undesired things if not carefully calibrated. For example, to use your example input, it would identify ((1)
(note the lack of a second rparen) as a match.
