You can use html2canvas plugin and jsPDF both. Process order: html to png & png to pdf
Example code:
jQuery('#part1').html2canvas({
onrendered: function( canvas ) {
var img1 = canvas.toDataURL('image/png');
}
});
jQuery('#part2').html2canvas({
onrendered: function( canvas ) {
var img2 = canvas.toDataURL('image/png');
}
});
jQuery('#part3').html2canvas({
onrendered: function( canvas ) {
var img3 = canvas.toDataURL('image/png');
}
});
var doc = new jsPDF('p', 'mm');
doc.addImage( img1, 'PNG', 0, 0, 210, 297); // A4 sizes
doc.addImage( img2, 'PNG', 0, 90, 210, 297); // img1 and img2 on first page
doc.addPage();
doc.addImage( img3, 'PNG', 0, 0, 210, 297); // img3 on second page
doc.save("file.pdf");
The naive approach:
MsgList.Where(x => !SentList.Any(y => y.MsgID == x.MsgID))
Be aware this will take up to m*n
operations as it compares every MsgID
in SentList
to each in MsgList
("up to" because it will short-circuit when it does happen to match).
Try this
let val = this.SurveysList.filter(xi => {
if (xi.id == parseInt(this.apiId ? '0' : this.apiId))
return xi.Description;
})
console.log('Description : ', val );
Using width/height on inline elements is not always a good idea.
You can use display: inline-block
instead
Use the set_facecolor(color)
method of the axes
object, which you've created one of the following ways:
You created a figure and axis/es together
fig, ax = plt.subplots(nrows=1, ncols=1)
You created a figure, then axis/es later
fig = plt.figure()
ax = fig.add_subplot(1, 1, 1) # nrows, ncols, index
You used the stateful API (if you're doing anything more than a few lines, and especially if you have multiple plots, the object-oriented methods above make life easier because you can refer to specific figures, plot on certain axes, and customize either)
plt.plot(...)
ax = plt.gca()
Then you can use set_facecolor
:
ax.set_facecolor('xkcd:salmon')
ax.set_facecolor((1.0, 0.47, 0.42))
As a refresher for what colors can be:
matplotlib.colors
Matplotlib recognizes the following formats to specify a color:
- an RGB or RGBA tuple of float values in
[0, 1]
(e.g.,(0.1, 0.2, 0.5)
or(0.1, 0.2, 0.5, 0.3)
);- a hex RGB or RGBA string (e.g.,
'#0F0F0F'
or'#0F0F0F0F'
);- a string representation of a float value in
[0, 1]
inclusive for gray level (e.g.,'0.5'
);- one of
{'b', 'g', 'r', 'c', 'm', 'y', 'k', 'w'}
;- a X11/CSS4 color name;
- a name from the xkcd color survey; prefixed with
'xkcd:'
(e.g.,'xkcd:sky blue'
);- one of
{'tab:blue', 'tab:orange', 'tab:green', 'tab:red', 'tab:purple', 'tab:brown', 'tab:pink', 'tab:gray', 'tab:olive', 'tab:cyan'}
which are the Tableau Colors from the ‘T10’ categorical palette (which is the default color cycle);- a “CN” color spec, i.e. 'C' followed by a single digit, which is an index into the default property cycle (
matplotlib.rcParams['axes.prop_cycle']
); the indexing occurs at artist creation time and defaults to black if the cycle does not include color.All string specifications of color, other than “CN”, are case-insensitive.
Most of the time when we download tomcat and extract the file a folder will be created:
C:\Program Files\apache-tomcat-9.0.1-windows-x64
Inside that actual tomcat folder will be there:
C:\Program Files\apache-tomcat-9.0.1-windows-x64\apache-tomcat-9.0.1
so while selecting you need to select inner folder:
C:\Program Files\apache-tomcat-9.0.1-windows-x64\apache-tomcat-9.0.1
instead of the outer.
$(".pushme").click(function () {
var button = $(this);
button.text(button.text() == "PUSH ME" ? "DON'T PUSH ME" : "PUSH ME")
});
This ternary operator has an implicit return.
If the expression before ?
is true
it returns "DON'T PUSH ME"
, else returns "PUSH ME"
This if-else statement:
if (condition) { return A }
else { return B }
has the equivalent ternary expression:
condition ? A : B
firstOrCreate()
checks for all the arguments to be present before it finds
a match. If not all arguments match, then a new instance of the model will be created.
If you only want to check on a specific field, then use firstOrCreate(['field_name' => 'value'])
with only one item in the array. This will return the first item that matches, or create a new one if not matches are found.
The difference between firstOrCreate()
and firstOrNew()
:
firstOrCreate()
will automatically create a new entry in the database if there is not match found. Otherwise it will give you the matched item.firstOrNew()
will give you a new model instance to work with if not match was found, but will only be saved to the database when you explicitly do so (calling save()
on the model). Otherwise it will give you the matched item.Choosing between one or the other depends on what you want to do. If you want to modify the model instance before it is saved for the first time (e.g. setting a name
or some mandatory field), you should use firstOrNew()
. If you can just use the arguments to immediately create a new model instance in the database without modifying it, you can use firstOrCreate()
.
Quite a busy one-liner, but here it is:
myarray
, is normalised with the max value at 1.0
.myarray
.0-255
range.np.uint8()

from matplotlib import cm
im = Image.fromarray(np.uint8(cm.gist_earth(myarray)*255))
with plt.savefig()

A small Node.js HTTP server listening on port 9080, parsing GET or POST data and sending it back to the client as part of the response is:
var sys = require('sys'),
url = require('url'),
http = require('http'),
qs = require('querystring');
var server = http.createServer(
function (request, response) {
if (request.method == 'POST') {
var body = '';
request.on('data', function (data) {
body += data;
});
request.on('end',function() {
var POST = qs.parse(body);
//console.log(POST);
response.writeHead( 200 );
response.write( JSON.stringify( POST ) );
response.end();
});
}
else if(request.method == 'GET') {
var url_parts = url.parse(request.url,true);
//console.log(url_parts.query);
response.writeHead( 200 );
response.write( JSON.stringify( url_parts.query ) );
response.end();
}
}
);
server.listen(9080);
Save it as parse.js
, and run it on the console by entering "node parse.js".
This answer will demonstrate the difference between implementation
, api
, and compile
on a project.
Let's say I have a project with three Gradle modules:
app
has myandroidlibrary
as dependencies. myandroidlibrary
has myjavalibrary
as dependencies.
myjavalibrary
has a MySecret
class
public class MySecret {
public static String getSecret() {
return "Money";
}
}
myandroidlibrary
has MyAndroidComponent
class that manipulate value from MySecret
class.
public class MyAndroidComponent {
private static String component = MySecret.getSecret();
public static String getComponent() {
return "My component: " + component;
}
}
Lastly, app
is only interested in the value from myandroidlibrary
TextView tvHelloWorld = findViewById(R.id.tv_hello_world);
tvHelloWorld.setText(MyAndroidComponent.getComponent());
Now, let's talk about dependencies...
app
need to consume :myandroidlibrary
, so in app
build.gradle use implementation
.
(Note: You can use api/compile too. But hold that thought for a moment.)
dependencies {
implementation project(':myandroidlibrary')
}
What do you think myandroidlibrary
build.gradle should look like? Which scope we should use?
We have three options:
dependencies {
// Option #1
implementation project(':myjavalibrary')
// Option #2
compile project(':myjavalibrary')
// Option #3
api project(':myjavalibrary')
}
What's the difference between them and what should I be using?
Compile or Api (option #2 or #3)
If you're using compile
or api
. Our Android Application now able to access myandroidcomponent
dependency, which is a MySecret
class.
TextView textView = findViewById(R.id.text_view);
textView.setText(MyAndroidComponent.getComponent());
// You can access MySecret
textView.setText(MySecret.getSecret());
Implementation (option #1)
If you're using implementation
configuration, MySecret
is not exposed.
TextView textView = findViewById(R.id.text_view);
textView.setText(MyAndroidComponent.getComponent());
// You can NOT access MySecret
textView.setText(MySecret.getSecret()); // Won't even compile
So, which configuration you should choose? That really depends on your requirement.
If you want to expose dependencies use api
or compile
.
If you don't want to expose dependencies (hiding your internal module) then use implementation
.
Note:
This is just a gist of Gradle configurations, refer to Table 49.1. Java Library plugin - configurations used to declare dependencies for more detailed explanation.

The checking of the presence of the member before assigning it is, in my opinion, quite ugly.
Kohana has a useful function to make selecting parameters simple.
You can make your own like so...
function arrayGet($array, $key, $default = NULL)
{
return isset($array[$key]) ? $array[$key] : $default;
}
And then do something like...
$page = arrayGet($_GET, 'p', 1);
Put your ScrollViewer in a DockPanel and set the DockPanel MaxHeight property
[...]
<DockPanel MaxHeight="700">
<ScrollViewer VerticalScrollBarVisibility="Auto">
<ItemsControl ItemSource ="{Binding ...}">
[...]
</ItemsControl>
</ScrollViewer>
</DockPanel>
[...]
you gave the following example in your question:
colnames(merger)[,1]<-"Date"
the problem is the comma: colnames() returns a vector, not a matrix, so the solution is:
colnames(merger)[1]<-"Date"
Put it inside an UIImageView
let logo = UIImage(named: "logo.png")
let imageView = UIImageView(image:logo)
self.navigationItem.titleView = imageView
It is whatever member of the enumeration represents the value 0
. Specifically, from the documentation:
The default value of an
enum E
is the value produced by the expression(E)0
.
As an example, take the following enum:
enum E
{
Foo, Bar, Baz, Quux
}
Without overriding the default values, printing default(E)
returns Foo
since it's the first-occurring element.
However, it is not always the case that 0
of an enum is represented by the first member. For example, if you do this:
enum F
{
// Give each element a custom value
Foo = 1, Bar = 2, Baz = 3, Quux = 0
}
Printing default(F)
will give you Quux
, not Foo
.
If none of the elements in an enum G
correspond to 0
:
enum G
{
Foo = 1, Bar = 2, Baz = 3, Quux = 4
}
default(G)
returns literally 0
, although its type remains as G
(as quoted by the docs above, a cast to the given enum type).
Prevent browser cache is not a good idea depending on the case. Looking for a solution I found solutions like this:
<link rel="stylesheet" type="text/css" href="meu.css?v=<?=filemtime($file);?>">
the problem here is that if the file is overwritten during an update on the server, which is my scenario, the cache is ignored because timestamp is modified even the content of the file is the same.
I use this solution to force browser to download assets only if its content is modified:
<link rel="stylesheet" type="text/css" href="meu.css?v=<?=hash_file('md5', $file);?>">
You can try this code in your Main class. That worked for me, but i have implemented methods in other way
try {
String receivedData = new AsyncTask().execute("http://yourdomain.com/yourscript.php").get();
}
catch (ExecutionException | InterruptedException ei) {
ei.printStackTrace();
}
My solution to get all attributes (not methods) of a class (if the class has a properly written docstring that has the attributes clearly spelled out):
def get_class_attrs(cls):
return re.findall(r'\w+(?=[,\)])', cls.__dict__['__doc__'])
This piece cls.__dict__['__doc__']
extracts the docstring of the class.
This article by Ian Griffiths gives two different solutions to the problem that he concludes are neat tricks that you should not use.
Use time module to convert data.
Code snippet:
import time
tring='20150103040500'
var = int(time.mktime(time.strptime(tring, '%Y%m%d%H%M%S')))
print var
I know this topic is a bit old, but I think I did something that may be useful for someone, so I'm posting it.
I compiled suggestions from this thread's answers into a procedure:
CREATE OR REPLACE PROCEDURE create_table_if_doesnt_exist(
p_table_name VARCHAR2,
create_table_query VARCHAR2
) AUTHID CURRENT_USER IS
n NUMBER;
BEGIN
SELECT COUNT(*) INTO n FROM user_tables WHERE table_name = UPPER(p_table_name);
IF (n = 0) THEN
EXECUTE IMMEDIATE create_table_query;
END IF;
END;
You can then use it in a following way:
call create_table_if_doesnt_exist('my_table', 'CREATE TABLE my_table (
id NUMBER(19) NOT NULL PRIMARY KEY,
text VARCHAR2(4000),
modified_time TIMESTAMP
)'
);
I know that it's kinda redundant to pass table name twice, but I think that's the easiest here.
Hope somebody finds above useful :-).

Putting it in the "web.config" works fine. The problem was that I got the MIME type wrong. Instead of or font/x-woff
it must be font/x-font-woff
application/font-woff
:
<system.webServer>
...
<staticContent>
<remove fileExtension=".woff" />
<mimeMap fileExtension=".woff" mimeType="application/font-woff" />
</staticContent>
</system.webServer>
See also this answer regarding the MIME type: https://stackoverflow.com/a/5142316/135441
Update 4/10/2013
Spec is now a recommendation and the MIME type is officially:
application/font-woff
Creating a new attribute class is a good suggestion. In my case, I wanted to specify 'default(DateTime)' or 'DateTime.MinValue' so that the Newtonsoft.Json serializer would ignore DateTime members without real values.
[JsonProperty( DefaultValueHandling = DefaultValueHandling.Ignore )]
[DefaultDateTime]
public DateTime EndTime;
public class DefaultDateTimeAttribute : DefaultValueAttribute
{
public DefaultDateTimeAttribute()
: base( default( DateTime ) ) { }
public DefaultDateTimeAttribute( string dateTime )
: base( DateTime.Parse( dateTime ) ) { }
}
Without the DefaultValue attribute, the JSON serializer would output "1/1/0001 12:00:00 AM" even though the DefaultValueHandling.Ignore option was set.
Instead of comparing the dates directly, compare the getTime() value of the date. The getTime() function returns the number of milliseconds since Jan 1, 1970 as an integer-- should be trivial to determine if one integer falls between two other integers.
Something like
if((check.getTime() <= to.getTime() && check.getTime() >= from.getTime())) alert("date contained");
You may use numpy.append()
...
import numpy
B = numpy.array([3])
A = numpy.array([1, 2, 2])
B = numpy.append( B , A )
print B
> [3 1 2 2]
This will not create two separate arrays but will append two arrays into a single dimensional array.
I recommend reading this post.

I used to encounter this same exact issue in the past with Google Admob SDK. Most recently, this happened when trying to add Validic libraries. I tried the same old good trick this time around as well and it worked in a jiffy.
1) Remove the frameworks, if already added.
2) Locate the framework in Finder and Drag & Drop them directly into the Project Navigator pane under your project tree.
3) Build the project and Whooo!
Not sure what makes the difference, but adding the frameworks by the official way of going to the section "Linked Framework & Libraries" under project settings page (TARGET) and linking from there does not work for me. Hope this helps.
The solution posted by Bjorn results in a "RuntimeError: Calling Tcl from different appartment" message on my computer (RedHat Enterprise 5, python 2.6.1). Bjorn might not have gotten this message, since, according to one place I checked, mishandling threading with Tkinter is unpredictable and platform-dependent.
The problem seems to be that app.start()
counts as a reference to Tk, since app contains Tk elements. I fixed this by replacing app.start()
with a self.start()
inside __init__
. I also made it so that all Tk references are either inside the function that calls mainloop()
or are inside functions that are called by the function that calls mainloop()
(this is apparently critical to avoid the "different apartment" error).
Finally, I added a protocol handler with a callback, since without this the program exits with an error when the Tk window is closed by the user.
The revised code is as follows:
# Run tkinter code in another thread
import tkinter as tk
import threading
class App(threading.Thread):
def __init__(self):
threading.Thread.__init__(self)
self.start()
def callback(self):
self.root.quit()
def run(self):
self.root = tk.Tk()
self.root.protocol("WM_DELETE_WINDOW", self.callback)
label = tk.Label(self.root, text="Hello World")
label.pack()
self.root.mainloop()
app = App()
print('Now we can continue running code while mainloop runs!')
for i in range(100000):
print(i)

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf
between host and guest (there is known performance issues if there are large numbers of files/directories).
/vagrant
in guestVagrant is mounting the current working directory (where Vagrantfile
resides) as /vagrant
in the guest, this is the default behaviour.
See docs
NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.
You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true
in your Vagrantfile
.
Based on the output /tmp
on host was NOT mounted during up time.
Use VAGRANT_INFO=debug vagrant up
or VAGRANT_INFO=debug vagrant reload
to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp
on host should be drwxrwxrwt
).
I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)
config.vm.synced_folder "/tmp", "/tmp/src"
output

This is my version of a bash script. It takes database name as a parameter and converts all tables to another charset and collation (given by another parameters or default value defined in the script).

Look at the Map interface, and at the concrete class HashMap.
To create a Map:
Map<String, String> assoc = new HashMap<String, String>();
To add a key-value pair:
assoc.put("name", "demo");
To retrieve the value associated with a key:
assoc.get("name")
And sure, you may create an array of Maps, as it seems to be what you want:
Map<String, String>[] assoc = ...
Firstly, understand that DateTime
objects aren't formatted. They just store the Year, Month, Day, Hour, Minute, Second, etc as a numeric value and the formatting occurs when you want to represent it as a string somehow. You can compare DateTime
objects without formatting them.
To compare an input date with DateTime.Now
, you need to first parse the input into a date and then compare just the Year/Month/Day portions:
DateTime inputDate;
if(!DateTime.TryParse(inputString, out inputDate))
throw new ArgumentException("Input string not in the correct format.");
if(inputDate.Date == DateTime.Now.Date) {
// Same date!
}

From what you say in your question (the service is not registered)
it seems that we are talking about a service not correctly installed. I will try to reinstall the application.
find . -name 'Lemon*.mp3' -print0 | xargs -0 -i mplayer '{}'
This helped in my case to delete different files with spaces. It should work too with mplayer. The necessary trick is the quotes. (Tested on Linux Xubuntu 14.04.)
I would stick with normal approach to call the file directly, but if you really want to call a function, have a look at JSON-RPC (JSON Remote Procedure Call).
You basically send a JSON string in a specific format to the server, e.g.
{ "method": "echo", "params": ["Hello JSON-RPC"], "id": 1}
which includes the function to call and the parameters of that function.
Of course the server has to know how to handle such requests.
Here is jQuery plugin for JSON-RPC and e.g. the Zend JSON Server as server implementation in PHP.
This might be overkill for a small project or less functions. Easiest way would be karim's answer. On the other hand, JSON-RPC is a standard.

If they are from the same table, I think UNION
is the command you're looking for.
(If you'd ever need to select values from columns of different tables, you should look at JOIN
instead...)
XSD : XML Schema Definition.
XML : eXtensible Markup Language.
WSDL : Web Service Definition Language.
I am not going to answer in technical terms. I am aiming this explanation at beginners.
It is not easy to communicate between two different applications that are developed using two different technologies. For example, a company in Chicago might develop a web application using Java and another company in New York might develop an application in C# and when these two companies decided to share information then XML comes into picture. It helps to store and transport data between two different applications that are developed using different technologies. Note: It is not limited to a programming language, please do research on the information transportation between two different apps.
XSD is a schema definition. By that what I mean is, it is telling users to develop their XML in such a schema. Please see below images, and please watch closely with "load-on-startup" element and its type which is integer. In the XSD image you can see it is meant to be integer value for the "load-on-startup" and hence when user created his/her XML they passed an int value to that particular element. As a reminder, XSD is a schema and style whereas XML is a form to communicate with another application or system. One has to see XSD and create XML in such a way or else it won't communicate with another application or system which has been developed with a different technology. A company in Chicago provides a XSD template for a company in Texas to write or generate their XML in the given XSD format. If the company in Texas failed to adhere with those rules or schema mentioned in XSD then it is impossible to expect correct information from the company in Chicago. There is so much to do after the above said story, which an amateur or newbie have to know while coding for some thing like I said above. If you really want to know what happens later then it is better to sit with senior software engineers who actually developed web services. Next comes WSDL, please follow the images and try to figure out where the WSDL will fit in.
***************========Below is partial XML image ==========***************

I had to create a sample WSDL for a web service called Book. Note, it is an XSD but you have to call it WSDL (Web Service Definition Language) because it is very specific for Web Services. The above WSDL (or in other words XSD) is created for a class called Book.java and it has created a SOAP service. How the SOAP web service created it is a different topic. One has to write a Java class and before executing it create as a web service the user has to make sure Axis2 API is installed and Tomcat to host web service is in place.
As a servicer (the one who allows others (clients) to access information or data from their systems ) actually gives the client (the one who needs to use servicer information or data) complete access to data through a Web Service, because no company on the earth willing to expose their Database for outsiders. Like my company, decided to give some information about products via Web Services, hence we had to create XSD template and pass-on to few of our clients who wants to work with us. They have to write some code to make complete use of the given XSD and make Web Service calls to fetch data from servicer and convert data returned into their suitable requirement and then display or publish data or information about the product on their website. A simple example would be FLIGHT Ticket booking. An airline will let third parties to use flight data on their site for ticket sales. But again there is much more to it, it is just not letting third party flight ticket agent to sell tickets, there will be synchronize and security in place. If there is no sync then there is 100 % chances more than 1 customer might buy same flight ticket from various sources.
I am hoping experts will contribute to my answer. It is really hard for newbie or novice to understand XML, XSD and then to work on Web Services.
You need a dict
:
my_dict = {'cheese': 'cake'}
Example code (from the docs):
>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True
You can read more about dictionaries here.
Since anonymous classes extend the given class you can store them in a variable.
eg.
Thread t = new Thread()
{
public void run() {
System.out.println("blah");
}
};
t.start();
Alternatively, you can just call the start method on the object you have immediately created.
new Thread()
{
public void run() {
System.out.println("blah");
}
}.start();
// similar to new Thread().start();
Though personally, I would always advise creating an anonymous instance of Runnable rather than Thread as the compiler will warn you if you accidentally get the method signature wrong (for an anonymous class it will warn you anyway I think, as anonymous classes can't define new non-private methods).
eg
new Thread(new Runnable()
{
@Override
public void run() {
System.out.println("blah");
}
}).start();
@article = user.articles.build(:title => "MainTitle")
@article.save

SleepEx
function (see http://msdn.microsoft.com/en-us/library/ms686307.aspx) is the best choise if your program directly or indirectly creates windows (for example use some COM objects). In the simples cases you can also use Sleep
.
Its just like creating a WAR
file of your project, you can do it in several ways (from Eclipse, command line, maven).
If you want to do from command line, the command is
jar -cvf my_web_app.war *
Which means, "compress everything in this directory into a file named my_web_app.war" (c=create, v=verbose, f=file)
The link you gave does actually describe the differences, but it's buried at the bottom of the page:

Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.
The conversion could be to normalize \r\n
to \n
(or vice-versa), or maybe ignoring characters beyond 0x7F (a-la 'text mode' in FTP). Personally I'd open everything in binary-mode and use a good text-encoding library for dealing with text.
Beware that when the mounted
event is fired on a component, not all Vue components are replaced yet, so the DOM may not be final yet.
To really simulate the DOM onload
event, i.e. to fire after the DOM is ready but before the page is drawn, use vm.$nextTick from inside mounted
:
mounted: function () {
this.$nextTick(function () {
// Will be executed when the DOM is ready
})
}
TL&DR: When you typically get data from a server, it is sent in bytes. The rationale is that these bytes will need to be 'decoded' by the recipient, who should know how to use the data. You should decode the binary upon arrival to not get 'b' (bytes) but instead a string.
Use case:
import requests
def get_data_from_url(url):
response = requests.get(url_to_visit)
response_data_split_by_line = response.content.decode('utf-8').splitlines()
return response_data_split_by_line
In this example, I decode the content that I received into UTF-8. For my purposes, I then split it by line, so I can loop through each line with a for loop.
Following short code can help:
df3 = df3.rename(columns={c: c.replace(' ', '') for c in df3.columns})
Remove spaces from columns.
/^.*?\bcat\b.*?\bmat\b.*?$/m
Using the m
modifier (which ensures the beginning/end metacharacters match on line breaks rather than at the very beginning and end of the string):
^
matches the line beginning.*?
matches anything on the line before...\b
matches a word boundary the first occurrence of a word boundary (as @codaddict discussed)cat
and another word boundary; note that underscores are treated as "word" characters, so _cat_
would not match*;.*?
: any characters before...mat
, boundary.*?
: any remaining characters before...$
: the end of the line.It's important to use \b
to ensure the specified words aren't part of longer words, and it's important to use non-greedy wildcards (.*?
) versus greedy (.*
) because the latter would fail on strings like "There is a cat on top of the mat which is under the cat." (It would match the last occurrence of "cat" rather than the first.)
* If you want to be able to match _cat_
, you can use:
/^.*?(?:\b|_)cat(?:\b|_).*?(?:\b|_)mat(?:\b|_).*?$/m
which matches either underscores or word boundaries around the specified words. (?:)
indicates a non-capturing group, which can help with performance or avoid conflicted captures.
Edit: A question was raised in the comments about whether the solution would work for phrases rather than just words. The answer is, absolutely yes. The following would match "A line which includes both the first phrase and the second phrase":
/^.*?(?:\b|_)first phrase here(?:\b|_).*?(?:\b|_)second phrase here(?:\b|_).*?$/m
Edit 2: If order doesn't matter you can use:
/^.*?(?:\b|_)(first(?:\b|_).*?(?:\b|_)second|second(?:\b|_).*?(?:\b|_)first)(?:\b|_).*?$/m
And if performance is really an issue here, it's possible lookaround (if your regex engine supports it) might (but probably won't) perform better than the above, but I'll leave both the arguably more complex lookaround version and performance testing as an exercise to the questioner/reader.
Edited per @Alan Moore's comment. I didn't have a chance to test it, but I'll take your word for it.
Few people appear, despite the many answers to this question, to have pointed out that dictionaries are un-ordered mappings, and so (until the blessing of insertion order with Python 3.7) the idea of the "first" entry in a dictionary literally made no sense. And even an OrderedDict
can only be accessed by numerical index using such uglinesses as mydict[mydict.keys()[0]]
(Python 2 only, since in Python 3 keys()
is a non-subscriptable iterator.)
From 3.7 onwards and in practice in 3,6 as well - the new behaviour was introduced then, but not included as part of the language specification until 3.7 - iteration over the keys, values or items of a dict (and, I believe, a set also) will yield the least-recently inserted objects first. There is still no simple way to access them by numerical index of insertion.
As to the question of selecting and "formatting" items, if you know the key you want to retrieve in the dictionary you would normally use the key as a subscript to retrieve it (my_var = mydict['Apple']
).
If you really do want to be able to index the items by entry number (ignoring the fact that a particular entry's number will change as insertions are made) then the appropriate structure would probably be a list of two-element tuples. Instead of
mydict = {
'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
'Grapes':{'Arabian':'25','Indian':'20'} }
you might use:
mylist = [
('Apple', {'American':'16', 'Mexican':10, 'Chinese':5}),
('Grapes', {'Arabian': '25', 'Indian': '20'}
]
Under this regime the first entry is mylist[0]
in classic list-endexed form, and its value is ('Apple', {'American':'16', 'Mexican':10, 'Chinese':5})
. You could iterate over the whole list as follows:
for (key, value) in mylist: # unpacks to avoid tuple indexing
if key == 'Apple':
if 'American' in value:
print(value['American'])
but if you know you are looking for the key "Apple", why wouldn't you just use a dict instead?
You could introduce an additional level of indirection by cacheing the list of keys, but the complexities of keeping two data structures in synchronisation would inevitably add to the complexity of your code.
I can't replicate the problem here:
$x = "this \n \t\t \n works.";
var_dump(preg_replace('/\s\s+/', ' ', $x));
// string(11) "this works."
I'm not sure if it was just a transcription error or not, but in your example, you're using a single-quoted string. \n
and \t
are only treated as new-line and tab if you've got a double quoted string. That is:
'\n\t' != "\n\t"
Edit: as Codaddict pointed out, \s\s+
won't replace a single tab character. I still don't think using \s+
is an efficient solution though, so how about this instead:
preg_replace('/(?:\s\s+|\n|\t)/', ' ', $x);
Just use special `
var lyrics = 'Never gonna give you up';
var html = `<div>${lyrics}</div>`;
You can see more examples here.
I'm not sure you can exclude packages explicitly with an <exclude-filter>, but I bet using a regex filter would effectively get you there:
<context:component-scan base-package="com.example">
<context:exclude-filter type="regex" expression="com\.example\.ignore\..*"/>
</context:component-scan>
To make it annotation-based, you'd annotate each class you wanted excluded for integration tests with something like @com.example.annotation.ExcludedFromITests. Then the component-scan would look like:
<context:component-scan base-package="com.example">
<context:exclude-filter type="annotation" expression="com.example.annotation.ExcludedFromITests"/>
</context:component-scan>
That's clearer because now you've documented in the source code itself that the class is not intended to be included in an application context for integration tests.
Try this one for current selection:
Sub A_SelectAllMakeTable2()
Dim tbl As ListObject
Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
tbl.TableStyle = "TableStyleMedium15"
End Sub
or equivalent of your macro (for Ctrl+Shift+End range selection):
Sub A_SelectAllMakeTable()
Dim tbl As ListObject
Dim rng As Range
Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
tbl.TableStyle = "TableStyleMedium15"
End Sub
The simplest use of bind()
is to make a function that, no matter
how it is called, is called with a particular this
value.
x = 9;
var module = {
x: 81,
getX: function () {
return this.x;
}
};
module.getX(); // 81
var getX = module.getX;
getX(); // 9, because in this case, "this" refers to the global object
// create a new function with 'this' bound to module
var boundGetX = getX.bind(module);
boundGetX(); // 81
Please refer this link for more information
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind
Try something like:-
ALTER TABLE table_name ADD CONSTRAINT [DF_table_name_Created]
DEFAULT (getdate()) FOR [created_at];
replacing table_name
with the name of your table.
Old post but "e" variable must be unique:
try {

throw new ApplicationException("Problem connecting to server");
} catch(Exception e) {
// Will the ApplicationException be caught here?
}
If you can use jquery then its simple
$("#txt").text()
You can convert a number to a string with n decimal places using the SPRINTF command:
>> x = 1.23; >> sprintf('%0.6f', x) ans = 1.230000 >> x = 1.23456789; >> sprintf('%0.6f', x) ans = 1.234568
You are trying to read xls
with explicit implementation poi classes for xlsx
.
G:\Selenium Jar Files\TestData\Data.xls
Either use HSSFWorkbook
and HSSFSheet
classes or make your implementation more generic by using shared interfaces, like;
Change:
XSSFWorkbook workbook = new XSSFWorkbook(file);
To:
org.apache.poi.ss.usermodel.Workbook workbook = WorkbookFactory.create(file);
And Change:
XSSFSheet sheet = workbook.getSheetAt(0);
To:
org.apache.poi.ss.usermodel.Sheet sheet = workbook.getSheetAt(0);
Using
calls Dispose()
after the using
-block is left, even if the code throws an exception.
So you usually use using
for classes that require cleaning up after them, like IO.
So, this using block:
using (MyClass mine = new MyClass())
{
mine.Action();
}
would do the same as:
MyClass mine = new MyClass();
try
{
mine.Action();
}
finally
{
if (mine != null)
mine.Dispose();
}
Using using
is way shorter and easier to read.
For the sake of completeness -- just because none of the previous answers mentioned this method -- if you are working with Node.js and don't have to care about browser compatibility, the desired effect is pretty easy to achieve with the built in inherits
of the util
module (official docs here).
For example, let's suppose you want to create a custom error class that takes an error code as the first argument and the error message as the second argument:
file custom-error.js:
'use strict';
var util = require('util');
function CustomError(code, message) {
Error.captureStackTrace(this, CustomError);
this.name = CustomError.name;
this.code = code;
this.message = message;
}
util.inherits(CustomError, Error);
module.exports = CustomError;
Now you can instantiate and pass/throw your CustomError
:
var CustomError = require('./path/to/custom-error');
// pass as the first argument to your callback
callback(new CustomError(404, 'Not found!'));
// or, if you are working with try/catch, throw it
throw new CustomError(500, 'Server Error!');
Note that, with this snippet, the stack trace will have the correct file name and line, and the error instance will have the correct name!
This happens due to the usage of the captureStackTrace
method, which creates a stack
property on the target object (in this case, the CustomError
being instantiated). For more details about how it works, check the documentation here.
It's not a better idea to override the core.common file of codeigniter. Because that's the more tested and system files....
I make a solution for this problem. In your ckeditor_helper.php file line- 65
if($k !== end (array_keys($data['config']))) {
$return .= ",";
}
Change this to-->
$segment = array_keys($data['config']);
if($k !== end($segment)) {
$return .= ",";
}
I think this is the best solution and then your problem notice will dissappear.
The shortest and best way is already answered, but the first thing I thought of was the mathematical way, so here it is:
def intlist(n):
q = n
ret = []
while q != 0:
q, r = divmod(q, 10) # Divide by 10, see the remainder
ret.insert(0, r) # The remainder is the first to the right digit
return ret
print intlist(3)
print '-'
print intlist(10)
print '--'
print intlist(137)
It's just another interesting approach, you definitely don't have to use such a thing in practical use cases.
According to SolrQuerySyntax, you can use q=-id:[* TO *]
.
jquery will provide you with this and more ...
if($("#something").val()){ //do stuff}
It took me a couple of days to pick it up, but it provides you with you with so much more functionality. An example below.
jQuery(document).ready(function() {
/* finds closest element with class divright/left and
makes all checkboxs inside that div class the same as selectAll...
*/
$("#selectAll").click(function() {
$(this).closest('.divright').find(':checkbox').attr('checked', this.checked);
});
});
Using double
to store large integers is dubious; the largest integer that can be stored reliably in double
is much smaller than DBL_MAX
. You should use long long
, and if that's not enough, you need your own arbitrary-precision code or an existing library.
Try putting this in your .htaccess file:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^sub.domain.com
RewriteRule ^(.*)$ /subdomains/sub/$1 [L,NC,QSA]
For a more general rule (that works with any subdomain, not just sub
) replace the last two lines with this:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com
RewriteRule ^(.*)$ subdomains/%1/$1 [L,NC,QSA]
For calling the method of one class within the second class, you have to first create the object of that class which method you want to call than with the object reference you can call the method.
class A {
public void fun(){
//do something
}
}
class B {
public static void main(String args[]){
A obj = new A();
obj.fun();
}
}
But in your case you have the static method in Date and TemperatureRange class. You can call your static method by using the class name directly like below code or by creating the object of that class like above code but static method ,mostly we use for creating the utility classes, so best way to call the method by using class name. Like in your case -
public static void main (String[] args){
String dateVal = Date.date("01","11,"12"); // calling the date function by passing some parameter.
String tempRangeVal = TemperatureRange.TempRange("80","20");
}
You can make an auth section in your .hgrc
or Mercurial.ini
file, like so:
[auth]
bb.prefix = https://bitbucket.org/repo/path
bb.username = foo
bb.password = foo_passwd
The ‘bb’ part is an arbitrary identifier and is used to match prefix with username and password - handy for managing different username/password combos with different sites (prefix)
You can also only specify the user name, then you will just have to type your password when you push.
I would also recommend to take a look at the keyring extension. Because it stores the password in your system’s key ring instead of a plain text file, it is more secure. It is bundled with TortoiseHg on Windows, and there is currently a discussion about distributing it as a bundled extension on all platforms.
It depends on how often you insert or read. You can increase the array by more than one if needed.
numberOfItems = ??
' ...
If numberOfItems+1 >= arr.Length Then
Array.Resize(arr, arr.Length + 10)
End If
arr(numberOfItems) = newItem
numberOfItems += 1
Also for A, you only need to get the array if needed.
Dim list As List(Of Integer)(arr) ' Do this only once, keep a reference to the list
' If you create a new List everything you add an item then this will never be fast
'...
list.Add(newItem)
arrayWasModified = True
' ...
Function GetArray()
If arrayWasModified Then
arr = list.ToArray()
End If
Return Arr
End Function
If you have the time, I suggest you convert it all to List and remove arrays.

The Cdata is a data which you may want to pass to an xml parser and still not interpreted as an xml.
Say for eg :- You have an xml which has encapsulates question/answer object . Such open fields can have any data which does not strictly fall under basic data type or xml defined custom data types. Like --Is this a correct tag for xml comment ? .-- You may have a requirement to pass it as it is without being interpreted by the xml parser as another child element. Here Cdata comes to your rescue . By declaring as Cdata you are telling the parser don't treat the data wrapped as an xml (though it may look like one )
The check for whether a commandline argument has been set can be [%1]==[]
, but, as Dave Costa points out, "%1"==""
will also work.
I also fixed a syntax error in the usage echo to escape the greater-than and less-than signs. In addition, the exit
needs a /B
argument otherwise CMD.exe
will quit.
@echo off
if [%1]==[] goto usage
@echo This should not execute
@echo Done.
goto :eof
:usage
@echo Usage: %0 ^<EnvironmentName^>
exit /B 1
The best thing would be to set your own error and exception handlers which will do something usefull like logging it in a file or emailing critical ones. http://www.php.net/set_error_handler
I was able to fix this on Windows 7 64-bit running Python 3.4.3 by running the set
command at a command prompt to determine the existing Visual Studio tools environment variable; in my case it was VS140COMNTOOLS
for Visual Studio Community 2015.
Then run the following (substituting the variable on the right-hand side if yours has a different name):
set VS100COMNTOOLS=%VS140COMNTOOLS%
This allowed me to install the PyCrypto module that was previously giving me the same error as the OP.
For a more permanent solution, add this environment variable to your Windows environment via Control Panel ("Edit the system environment variables"), though you might need to use the actual path instead of the variable substitution.
Test t;
, calls the default constructor, which allocates a new array of integers. This is fine, and your expected behavior.
Trouble comes when you push t
into your queue using q.push(t)
. If you're familiar with Java, C#, or almost any other object-oriented language, you might expect the object you created earler to be added to the queue, but C++ doesn't work that way.
When we take a look at std::queue::push
method, we see that the element that gets added to the queue is "initialized to a copy of x." It's actually a brand new object that uses the copy constructor to duplicate every member of your original Test
object to make a new Test
.
Your C++ compiler generates a copy constructor for you by default! That's pretty handy, but causes problems with pointer members. In your example, remember that int *myArray
is just a memory address; when the value of myArray
is copied from the old object to the new one, you'll now have two objects pointing to the same array in memory. This isn't intrinsically bad, but the destructor will then try to delete the same array twice, hence the "double free or corruption" runtime error.
The first step is to implement a copy constructor, which can safely copy the data from one object to another. For simplicity, it could look something like this:
Test(const Test& other){
myArray = new int[10];
memcpy( myArray, other.myArray, 10 );
}
Now when you're copying Test objects, a new array will be allocated for the new object, and the values of the array will be copied as well.
We're not completely out trouble yet, though. There's another method that the compiler generates for you that could lead to similar problems - assignment. The difference is that with assignment, we already have an existing object whose memory needs to be managed appropriately. Here's a basic assignment operator implementation:
Test& operator= (const Test& other){
if (this != &other) {
memcpy( myArray, other.myArray, 10 );
}
return *this;
}
The important part here is that we're copying the data from the other array into this object's array, keeping each object's memory separate. We also have a check for self-assignment; otherwise, we'd be copying from ourselves to ourselves, which may throw an error (not sure what it's supposed to do). If we were deleting and allocating more memory, the self-assignment check prevents us from deleting memory from which we need to copy.
There is an option “unlimited scrollback buffer” which you can find under Preferences > Profiles > Terminal
or you can just pump up number of lines that you want to have in history in the same place.
The message "DL is deprecated, please use Fiddle" is not an error; it's only a warning.
Solution:
You can ignore this in 3 simple steps.
Step 1. Goto C:\RailsInstaller\Ruby2.1.0\lib\ruby\2.1.0
Step 2. Then find dl.rb and open the file with any online editors like Aptana,sublime text etc
Step 3. Comment the line 8 with '#' ie # warn "DL is deprecated, please use Fiddle" .
That's it, Thank you.
change the position absolute of div busy to fixed
Please note that in upcoming version of C# which is 8, the answers are not true.
All the reference types are non-nullable by default
and you can actually do the following:
public string? MyNullableString;
this.MyNullableString = null; //Valid
However,
public string MyNonNullableString;
this.MyNonNullableString = null; //Not Valid and you'll receive compiler warning.
The important thing here is to show the intent of your code. If the "intent" is that the reference type can be null, then mark it so otherwise assigning null value to non-nullable would result in compiler warning.
You can use this in the bat
script:
rd /s /q "c:\folder a"
Now, just change c:\folder a
to your folder's location. Quotation is only needed when your folder name contains spaces.
Use the -printcert
command like this:
keytool -printcert -file certificate.pem
Yes.
int minx, miny, maxx,maxy;
do {
printf("enter four integers: ");
} while (scanf("%d %d %d %d", &minx, &miny, &maxx, &maxy)!=4);
The loop is just to demonstrate that scanf returns the number of fields succesfully read (or EOF).
Shift + Alt + F does the job just fine in 1.17.2 and above.
CSS generated content can solve this for you:
div {_x000D_
position: relative;_x000D_
}_x000D_
_x000D_
_x000D_
/* Main div for border to extend to 50% from bottom left corner */_x000D_
_x000D_
div:after {_x000D_
content: "";_x000D_
background: black;_x000D_
position: absolute;_x000D_
bottom: 0;_x000D_
left: 0;_x000D_
height: 50%;_x000D_
width: 1px;_x000D_
}
_x000D_
<div>Lorem Ipsum</div>
_x000D_
(note - the content: "";
declaration is necessary in order for the pseudo-element to render)
This method also works just fine:
div.container {
display: flex;
justify-content: center; /* For horizontal alignment */
align-items: center; /* For vertical alignment */
}
For the inner <div>
, the only condition is that its height
and width
must not be larger than the ones of its container.
Use this Code in code behind
Div_Card.Style["background-image"] = Page.ResolveUrl(Session["Img_Path"].ToString());
You can use a WScript
object and call the Sleep
method on it:
Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds
Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):
Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000
Choose one from, where :my_date
is a string input parameter of yyyy-MM-dd
format:
SELECT EXTRACT(YEAR FROM CAST(:my_date AS DATE));
or
SELECT DATE_PART('year', CAST(:my_date AS DATE));
Better use CAST
than ::
as there may be conflicts with input parameters.
PCDATA
is text that will be parsed by a parser. Tags inside the text
will be treated as markup and entities will be expanded. CDATA
is text that will not be parsed by a parser. Tags inside the text will
not be treated as markup and entities will not be expanded.By default, everything is PCDATA
. In the following example, ignoring the root, <bar>
will be parsed, and it'll have no content, but one child.
<?xml version="1.0"?>
<foo>
<bar><test>content!</test></bar>
</foo>
When we want to specify that an element will only contain text, and no child elements, we use the keyword PCDATA
, because this keyword specifies that the element must contain parsable character data – that is , any text except the characters less-than (<
) , greater-than (>
) , ampersand (&
), quote('
) and double quote ("
).
In the next example, <bar>
contains CDATA
. Its content will not be parsed and is thus <test>content!</test>
.
<?xml version="1.0"?>
<foo>
<bar><![CDATA[<test>content!</test>]]></bar>
</foo>
There are several content models in SGML. The #PCDATA
content model says that an element may contain plain text. The "parsed" part of it means that markup (including PIs, comments and SGML directives) in it is parsed instead of displayed as raw text. It also means that entity references are replaced.
Another type of content model allowing plain text contents is CDATA
. In XML, the element content model may not implicitly be set to CDATA
, but in SGML, it means that markup and entity references are ignored in the contents of the element. In attributes of CDATA
type however, entity references are replaced.
In XML, #PCDATA
is the only plain text content model. You use it if you at all want to allow text contents in the element. The CDATA
content model may be used explicitly through the CDATA
block markup in #PCDATA
, but element contents may not be defined as CDATA
per default.
In a DTD, the type of an attribute that contains text must be CDATA
. The CDATA
keyword in an attribute declaration has a different meaning than the CDATA
section in an XML document. In a CDATA
section all characters are legal (including <
,>
,&
,'
and "
characters), except the ]]>
end tag.
#PCDATA
is not appropriate for the type of an attribute. It is used for the type of "leaf" text.
#PCDATA
is prepended by a hash in the content model to distinguish this keyword from an element named PCDATA
(which would be perfectly legal).
"2.7.0_bf4fda703454".split("_")
gives a list of strings:
In [1]: "2.7.0_bf4fda703454".split("_")
Out[1]: ['2.7.0', 'bf4fda703454']
This splits the string at every underscore. If you want it to stop after the first split, use "2.7.0_bf4fda703454".split("_", 1)
.
If you know for a fact that the string contains an underscore, you can even unpack the LHS and RHS into separate variables:
In [8]: lhs, rhs = "2.7.0_bf4fda703454".split("_", 1)
In [9]: lhs
Out[9]: '2.7.0'
In [10]: rhs
Out[10]: 'bf4fda703454'
An alternative is to use partition()
. The usage is similar to the last example, except that it returns three components instead of two. The principal advantage is that this method doesn't fail if the string doesn't contain the separator.
pytest constantly evolves and with one of the nice changes in the recent past it is now possible to simultaneously test for
Two examples from the documentation:
with pytest.raises(ValueError, match='must be 0 or None'):
raise ValueError('value must be 0 or None')
with pytest.raises(ValueError, match=r'must be \d+$'):
raise ValueError('value must be 42')
I have been using that approach in a number of projects and like it very much.
As you know JBoss is a purely filesystem based installation. To install you simply unzip a file and thats it. Once you install a certain folder structure is created by default and as you run the JBoss instance for the first time, it creates additional folders for runtime operation. For comparison here is the structure of JBoss AS 7 before and after you start for the first time
Before
jboss-as-7
|
|---> standalone
| |----> lib
| |----> configuration
| |----> deployments
|
|---> domain
|....
After
jboss-as-7
|
|---> standalone
| |----> lib
| |----> configuration
| |----> deployments
| |----> tmp
| |----> data
| |----> log
|
|---> domain
|....
As you can see 3 new folders are created (log, data & tmp). These folders can all be deleted without effecting the application deployed in deployments folder unless your application generated Data that's stored in those folders. In development, its ok to delete all these 3 new folders assuming you don't have any need for the logs and data stored in "data" directory.
For production, ITS NOT RECOMMENDED to delete these folders as there maybe application generated data that stores certain state of the application. For ex, in the data folder, the appserver can save critical Tx rollback logs. So contact your JBoss Administrator if you need to delete those folders for any reason in production.
Good luck!
I got this error while loading data when using docker[1]. The solution worked after I followed these next steps. Initially, I created the database and table datavault
and fdata
. When I tried to import the data[2], I got the error[3]. Then I did:
SET GLOBAL local_infile = 1;
SHOW VARIABLES LIKE 'local_infile';
mysql -P 3306 -u required --local-infile=1 -p
, see [4] for user creation.use datavault;
drop table fdata;
CREATE TABLE fdata (fID INT, NAME VARCHAR(64), LASTNAME VARCHAR(64), EMAIL VARCHAR(128), GENDER VARCHAR(12), IPADDRESS VARCHAR(40));
For completeness, I would add I was running the mysql version inside the container via docker exec -it testdb sh
. The mysql version was mysql Ver 8.0.17 for Linux on x86_64 (MySQL Community Server - GPL). This was also tested with mysql.exe Ver 14.14 Distrib 5.7.14, for Win64 (x86_64) which was another version of mysql from WAMP64. The associated commands used are listed in [5].

and it successfully loaded the data easily checked after running select * from fdata limit 10;
.Your json string is wrapped within square brackets ([]
), hence it is interpreted as array instead of single RetrieveMultipleResponse
object. Therefore, you need to deserialize it to type collection of RetrieveMultipleResponse
, for example :
var objResponse1 =
JsonConvert.DeserializeObject<List<RetrieveMultipleResponse>>(JsonStr);
Starting with Python 2.6 you can use anything implementing the TextIOBase
API from the io module as a replacement.
This solution also enables you to use sys.stdout.buffer.write()
in Python 3 to write (already) encoded byte strings to stdout (see stdout in Python 3).
Using StringIO
wouldn't work then, because neither sys.stdout.encoding
nor sys.stdout.buffer
would be available.
A solution using TextIOWrapper:
import sys
from io import TextIOWrapper, BytesIO
# setup the environment
old_stdout = sys.stdout
sys.stdout = TextIOWrapper(BytesIO(), sys.stdout.encoding)
# do something that writes to stdout or stdout.buffer
# get output
sys.stdout.seek(0) # jump to the start
out = sys.stdout.read() # read output
# restore stdout
sys.stdout.close()
sys.stdout = old_stdout
This solution works for Python 2 >= 2.6 and Python 3.
Please note that our new sys.stdout.write()
only accepts unicode strings and sys.stdout.buffer.write()
only accepts byte strings.
This might not be the case for old code, but is often the case for code that is built to run on Python 2 and 3 without changes, which again often makes use of sys.stdout.buffer
.
You can build a slight variation that accepts unicode and byte strings for write()
:
class StdoutBuffer(TextIOWrapper):
def write(self, string):
try:
return super(StdoutBuffer, self).write(string)
except TypeError:
# redirect encoded byte strings directly to buffer
return super(StdoutBuffer, self).buffer.write(string)
You don't have to set the encoding of the buffer the sys.stdout.encoding, but this helps when using this method for testing/comparing script output.
let's assume your environment name is 'demo' and you are using anaconda and want to create a virtual environment:
(if you want python3)
conda create -n demo python=3
(if you want python2)
conda create -n demo python=2
After running above command you have to activate the environment by bellow command:
source activate demo
Multi-value when and no-value case:
print "Enter your grade: "
grade = gets.chomp
case grade
when "A", "B"
puts 'You pretty smart!'
when "C", "D"
puts 'You pretty dumb!!'
else
puts "You can't even use a computer!"
end
And a regular expression solution here:
print "Enter a string: "
some_string = gets.chomp
case
when some_string.match(/\d/)
puts 'String has numbers'
when some_string.match(/[a-zA-Z]/)
puts 'String has letters'
else
puts 'String has no numbers or letters'
end
It annoys me for days. And finally I make use of the CSS property selector to solve it.
[data-reactroot]
{height: 100% !important; }
If all you have is the iterator, then no, there is no "better" way. If the iterator comes from a collection you could as that for size.
Keep in mind that Iterator is just an interface for traversing distinct values, you would very well have code such as this
new Iterator<Long>() {
final Random r = new Random();
@Override
public boolean hasNext() {
return true;
}
@Override
public Long next() {
return r.nextLong();
}
@Override
public void remove() {
throw new IllegalArgumentException("Not implemented");
}
};
or
new Iterator<BigInteger>() {
BigInteger next = BigInteger.ZERO;
@Override
public boolean hasNext() {
return true;
}
@Override
public BigInteger next() {
BigInteger current = next;
next = next.add(BigInteger.ONE);
return current;
}
@Override
public void remove() {
throw new IllegalArgumentException("Not implemented");
}
};
I think what you want to achieve is with the collaboration of "@mouseover and @mouseleave" or "@mouseenter and @mouseleave"
And I think, It's better to use the 2nd pair so that you can achieve the hover effect and call functionlaities on that.
<div @mouseenter="activeHover = true" @mouseleave="activeHover = false" >
<p v-if="activeHover"> This will be showed on hover </p>
<p v-if ="!activeHover"> This will be showed in simple cases </p>
</div>
on vue instance
data : {
activeHover : false
}
I hope, it will help others as well :)
By default when you configuring Python source, zlib module is disabled, so you can enable it using option --with-zlib when you configure it. So it becomes

It's probably the same problem with cultures as presented in this related SO-thread: Why can't DateTime.ParseExact() parse "9/1/2009" using "M/d/yyyy"
You already specified the culture, so try escaping the slashes.
class methods
are methods which are declared as static. The method can be called without creating an instance of the class. Class methods can only operate on class members and not on instance members as class methods are unaware of instance members. Instance methods of the class can also not be called from within a class method unless they are being called on an instance of that class.
Instance methods
on the other hand require an instance of the class to exist before they can be called, so an instance of a class needs to be created by using the new keyword. Instance methods operate on specific instances of classes. Instance methods are not declared as static.
For vector graphics, ImageMagick has both a render resolution and an output size that are independent of each other.
Try something like
convert -density 300 image.eps -resize 1024x1024 image.jpg
Which will render your eps at 300dpi. If 300 * width > 1024, then it will be sharp. If you render it too high though, you waste a lot of memory drawing a really high-res graphic only to down sample it again. I don't currently know of a good way to render it at the "right" resolution in one IM command.
The order of the arguments matters! The -density X
argument needs to go before image.eps
because you want to affect the resolution that the input file is rendered at.
This is not super obvious in the manpage for convert
, but is hinted at:
SYNOPSIS
convert [input-option] input-file [output-option] output-file
The second one is fastest. Using strlen
will be close if the string is indeed empty, but strlen
will always iterate through every character of the string, so if it is not empty, it will do much more work than you need it to.
As James mentioned, the third option wipes the string out before checking, so the check will always succeed but it will be meaningless.
When floating elements exist on the page, non-floating elements wrap around the floating elements, similar to how text goes around a picture in a newspaper. From a document perspective (the original purpose of HTML), this is how floats work.
float
vs display:inline
Before the invention of display:inline-block
, websites use float
to set elements beside each other. float
is preferred over display:inline
since with the latter, you can't set the element's dimensions (width and height) as well as vertical paddings (top and bottom) - which floated elements can do since they're treated as block elements.
The main problem is that we're using float
against its intended purpose.
Another is that while float
allows side-by-side block-level elements, floats do not impart shape to its container. It's like position:absolute
, where the element is "taken out of the layout". For instance, when an empty container contains a floating 100px x 100px <div>
, the <div>
will not impart 100px in height to the container.
Unlike position:absolute
, it affects the content that surrounds it. Content after the floated element will "wrap" around the element. It starts by rendering beside it and then below it, like how newspaper text would flow around an image.
What clearfix does is to force content after the floats or the container containing the floats to render below it. There are a lot of versions for clear-fix, but it got its name from the version that's commonly being used - the one that uses the CSS property clear
.
Here are several ways to do clearfix , depending on the browser and use case. One only needs to know how to use the clear
property in CSS and how floats render in each browser in order to achieve a perfect cross-browser clear-fix.
Your provided style is a form of clearfix with backwards compatibility. I found an article about this clearfix. It turns out, it's an OLD clearfix - still catering the old browsers. There is a newer, cleaner version of it in the article also. Here's the breakdown:
The first clearfix you have appends an invisible pseudo-element, which is styled clear:both
, between the target element and the next element. This forces the pseudo-element to render below the target, and the next element below the pseudo-element.
The second one appends the style display:inline-block
which is not supported by earlier browsers. inline-block is like inline but gives you some properties that block elements, like width, height as well as vertical padding. This was targeted for IE-MAC.
This was the reapplication of display:block
due to IE-MAC rule above. This rule was "hidden" from IE-MAC.
All in all, these 3 rules keep the .clearfix
working cross-browser, with old browsers in mind.
The scaling on your example figure is a bit strange but you can force it by plotting the index of each x-value and then setting the ticks to the data points:
import matplotlib.pyplot as plt
x = [0.00001,0.001,0.01,0.1,0.5,1,5]
# create an index for each tick position
xi = list(range(len(x)))
y = [0.945,0.885,0.893,0.9,0.996,1.25,1.19]
plt.ylim(0.8,1.4)
# plot the index for the x-values
plt.plot(xi, y, marker='o', linestyle='--', color='r', label='Square')
plt.xlabel('x')
plt.ylabel('y')
plt.xticks(xi, x)
plt.title('compare')
plt.legend()
plt.show()
I was facing similar issue on Linux mint what I did was found out Debian version using,
$ cat /etc/debian_version

That may help those who works on Kotlin you can use extension function so create a kotlin file let's say "util.kt" and add this piece of code
fun Fragment.addChildFragment(fragment: Fragment, frameId: Int) {
val transaction = childFragmentManager.beginTransaction()
transaction.replace(frameId, fragment).commit()
}
Let's say this is the class of the child
class InputFieldPresentation: Fragment()
{
var views: View? = null
override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?,
savedInstanceState: Bundle?): View? {
views = inflater!!.inflate(R.layout.input_field_frag, container, false)
return views
}
override fun onViewCreated(view: View?, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
...
}
...
}
Now you can add the children to the father fragment like this
FatherPresentation:Fragment()
{
...
override fun onViewCreated(view: View?, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
val fieldFragment= InputFieldPresentation()
addChildFragment(fieldFragment,R.id.fragmet_field)
}
...
}
where R.id.fragmet_field is the id of the layout which will contain the fragment.This lyout is inside the father fragment of course. Here is an example
father_fragment.xml:
<LinearLayout android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android"
>
...
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:id="@+id/fragmet_field"
android:orientation="vertical"
>
</LinearLayout>
...
</LinearLayout>

As long as people still stuck in this issue and we are in 2020 already. I get a pure CSS solution by giving the drop down menu a flex display
this snippet works great with datatable-scroll-wrap
class
.datatable-scroll-wrap .dropdown.dropup.open .dropdown-menu {
display: flex;
}
.datatable-scroll-wrap .dropdown.dropup.open .dropdown-menu li a {
display: flex;
}
This library is our standard for uuid generation and parsing:
I personally think that it's more important for the code to be readable and editable than performant. Whichever one you find easier to look at and it should be the one you choose for above factors. You can write it as:
$('#box').append(
$('<div/>')
.attr("id", "newDiv1")
.addClass("newDiv purple bloated")
.append("<span/>")
.text("hello world")
);
And your first Method as:
// create an element with an object literal, defining properties
var $e = $("<div>", {id: "newDiv1", name: 'test', class: "aClass"});
$e.click(function(){ /* ... */ });
// add the element to the body
$("#box").append($e);
But as far as readability goes; the jQuery approach is my favorite. Follow this Helpful jQuery Tricks, Notes, and Best Practices
The easiest way I've found to create postscripts is the following, using the setEPS()
command:
setEPS()
postscript("whatever.eps")
plot(rnorm(100), main="Hey Some Data")
dev.off()
There's no way to stop execution of your code as you would do with a procedural language. You can instead make use of setTimeout and some trickery to get a parametrized timeout:
for (var i = 1; i <= 5; i++) {
var tick = function(i) {
return function() {
console.log(i);
}
};
setTimeout(tick(i), 500 * i);
}

Since you are fetching based on a single column value you can simplify your query likewise:
$reservations = Reservation::whereBetween('reservation_from', array($from, $to))->get();

If not all of your document scrolls, say, when you have a scrolling div
within the document, then the above solutions won't work without adaptations. Here's how to check whether the div's scrollbar has hit the bottom:
$('#someScrollingDiv').on('scroll', function() {
let div = $(this).get(0);
if(div.scrollTop + div.clientHeight >= div.scrollHeight) {
// do the lazy loading here
}
});
I got this error in Expo because I had exported the wrong component name, e.g.
const Wonk = props => (
<Text>Hi!</Text>
)
export default Stack;
This is not "auto-completion", this is automation. One common tool for these things is called Expect.
You might also get away with just piping input from yes
.
It means the path you input caused an error. In your LD_PRELOAD
command, modify the path like the error tips:
/usr/lib/liblunar-calendar-preload.so
Vlookup
is good if the reference values (column A, sheet 1) are in ascending order. Another option is Index and Match, which can be used no matter the order (As long as the values in column a, sheet 1 are unique)
This is what you would put in column B on sheet 2
=INDEX(Sheet1!A$1:B$6,MATCH(A1,Sheet1!A$1:A$6),2)
Setting Sheet1!A$1:B$6
and Sheet1!A$1:A$6
as named ranges makes it a little more user friendly.

Here is a bit specific example, I would like to show. Say you have many duplicate entries in some of your rows. If you have string entries you could easily use string methods to find all indexes to drop.
ind_drop = df[df['column_of_strings'].apply(lambda x: x.startswith('Keyword'))].index
And now to drop those rows using their indexes
new_df = df.drop(ind_drop)

An XSD is a formal contract that specifies how an XML document can be formed. It is often used to validate an XML document, or to generate code from.
IEEE 754 defines 1.0 / 0.0
as Infinity and -1.0 / 0.0
as -Infinity and 0.0 / 0.0
as NaN.
By the way, floating point values also have -0.0
and so 1.0/ -0.0
is -Infinity
.
Integer arithmetic doesn't have any of these values and throws an Exception instead.
To check for all possible values (e.g. NaN, 0.0, -0.0) which could produce a non finite number you can do the following.
if (Math.abs(tab[i] = 1 / tab[i]) < Double.POSITIVE_INFINITY)
throw new ArithmeticException("Not finite");
You can also use DateTime.Now.ToString("yyyy-MM-dd")
for the date, and DateTime.Now.ToString("hh:mm:ss")
for the time.

I hope you find it useful.
If you know your super class by name, you can do something like this:
function Base() {
}
Base.prototype.foo = function() {
console.log('called foo in Base');
}
function Sub() {
}
Sub.prototype = new Base();
Sub.prototype.foo = function() {
console.log('called foo in Sub');
Base.prototype.foo.call(this);
}
var base = new Base();
base.foo();
var sub = new Sub();
sub.foo();
This will print
called foo in Base
called foo in Sub
called foo in Base
as expected.
Using Bootstrap's built in .center-block
class, which sets margin left and right to auto
:
<iframe class="center-block" width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen=""></iframe>
Or using the built in .text-center
class, which sets text-align: center
:
<div class="text-center">
<iframe width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen=""></iframe>
</div>
The solution in my case was to take any special characters out of the URL you're trying to access. I had a tilde (~) and a percentage symbol in there, and the $.get() call failed silently.
Example for a vertical stackview/scrollview (using the EasyPeasy
for autolayout):
let scrollView = UIScrollView()
self.view.addSubview(scrollView)
scrollView <- [
Edges(),
Width().like(self.view)
]
let stackView = UIStackView(arrangedSubviews: yourSubviews)
stackView.axis = .vertical
stackView.distribution = .fill
stackView.spacing = 10
scrollView.addSubview(stackView)
stackView <- [
Edges(),
Width().like(self.view)
]
Just make sure that each of your subview's height is defined!
On this web page, I see that:
"Remember that the dot is not a metacharacter inside a character class, so we do not need to escape it with a backslash."
So I guess the escaping of it is unnecessary...
If you are looking to avoid multiple code lines to save space, maybe this syntax could be useful:
java.util.ArrayList lisFieldNames = new ArrayList() {
{
add("value1");
add("value2");
}
};
Removing new lines, you can show it compressed as:
java.util.ArrayList lisFieldNames = new ArrayList() {
{
add("value1"); add("value2"); (...);
}
};
just had the same issue, but i could not find the conflicting branch anymore.
in my case the repo had and "foo" branch before, but not anymore and i tried to create and checkout "foo/bar" from remote. As i said "foo" did not exist anymore, but the issue persisted.
In the end, the branch "foo" was still in the .git/config file, after deleting it everything was alright :)
thank-you Ignacio Vazquez-Abrams
i adapted slightly for better ease of use :)
placed at top of script
NEW_LINE=$'\n'
then to use easily with other variables
variable1="test1"
variable2="test2"

Choose dlib .whl file according to your installed python version. For example if installed python version is 3.6.7 , 64bit system or if python is 3.5.0 32 bit then choose dlib-19.5.1-cp36-cp36m-win_amd64.whl and dlib-18.17.100-cp35-none-win32.whl respectively.
Bolded text says the python supporting version.

You probably have some other "Date" class imported somewhere (or you have a Date class in you package, which does not need to be imported). With "import java.util.*" you are using the "other" Date. In this case it's best to explicitly specify java.util.Date in the code.
Or better, try to avoid naming your classes "Date".
I disagree with the selected answer, and as davidxxx correctly pointed out, getReference does not provide such behaviour of dynamic updations without select. I asked a question concerning the validity of this answer, see here - cannot update without issuing select on using setter after getReference() of hibernate JPA.
I quite honestly haven't seen anybody who's actually used that functionality. ANYWHERE. And i don't understand why it's so upvoted.
Now first of all, no matter what you call on a hibernate proxy object, a setter or a getter, an SQL is fired and the object is loaded.
But then i thought, so what if JPA getReference() proxy doesn't provide that functionality. I can just write my own proxy.
Now, we can all argue that selects on primary keys are as fast as a query can get and it's not really something to go to great lengths to avoid. But for those of us who can't handle it due to one reason or another, below is an implementation of such a proxy. But before i you see the implementation, see it's usage and how simple it is to use.
USAGE
Order example = ProxyHandler.getReference(Order.class, 3);
example.setType("ABCD");
example.setCost(10);
PersistenceService.save(example);
And this would fire the following query -
UPDATE Order SET type = 'ABCD' and cost = 10 WHERE id = 3;
and even if you want to insert, you can still do PersistenceService.save(new Order("a", 2)); and it would fire an insert as it should.
IMPLEMENTATION
Add this to your pom.xml -
<dependency>
<groupId>cglib</groupId>
<artifactId>cglib</artifactId>
<version>3.2.10</version>
</dependency>
Make this class to create dynamic proxy -
@SuppressWarnings("unchecked")
public class ProxyHandler {
public static <T> T getReference(Class<T> classType, Object id) {
if (!classType.isAnnotationPresent(Entity.class)) {
throw new ProxyInstantiationException("This is not an entity!");
}
try {
Enhancer enhancer = new Enhancer();
enhancer.setSuperclass(classType);
enhancer.setCallback(new ProxyMethodInterceptor(classType, id));
enhancer.setInterfaces((new Class<?>[]{EnhancedProxy.class}));
return (T) enhancer.create();
} catch (Exception e) {
throw new ProxyInstantiationException("Error creating proxy, cause :" + e.getCause());
}
}
Make an interface with all the methods -
public interface EnhancedProxy {
public String getJPQLUpdate();
public HashMap<String, Object> getModifiedFields();
}
Now, make an interceptor which will allow you to implement these methods on your proxy -
import com.anil.app.exception.ProxyInstantiationException;
import javafx.util.Pair;
import net.sf.cglib.proxy.MethodInterceptor;
import net.sf.cglib.proxy.MethodProxy;
import javax.persistence.Id;
import java.lang.reflect.Field;
import java.lang.reflect.Method;
import java.util.*;
/**
* @author Anil Kumar
*/
public class ProxyMethodInterceptor implements MethodInterceptor, EnhancedProxy {
private Object target;
private Object proxy;
private Class classType;
private Pair<String, Object> primaryKey;
private static HashSet<String> enhancedMethods;
ProxyMethodInterceptor(Class classType, Object id) throws IllegalAccessException, InstantiationException {
this.classType = classType;
this.target = classType.newInstance();
this.primaryKey = new Pair<>(getPrimaryKeyField().getName(), id);
}
static {
enhancedMethods = new HashSet<>();
for (Method method : EnhancedProxy.class.getDeclaredMethods()) {
enhancedMethods.add(method.getName());
}
}
@Override
public Object intercept(Object obj, Method method, Object[] args, MethodProxy proxy) throws Throwable {
//intercept enhanced methods
if (enhancedMethods.contains(method.getName())) {
this.proxy = obj;
return method.invoke(this, args);
}
//else invoke super class method
else
return proxy.invokeSuper(obj, args);
}
@Override
public HashMap<String, Object> getModifiedFields() {
HashMap<String, Object> modifiedFields = new HashMap<>();
try {
for (Field field : classType.getDeclaredFields()) {
field.setAccessible(true);
Object initialValue = field.get(target);
Object finalValue = field.get(proxy);
//put if modified
if (!Objects.equals(initialValue, finalValue)) {
modifiedFields.put(field.getName(), finalValue);
}
}
} catch (Exception e) {
return null;
}
return modifiedFields;
}
@Override
public String getJPQLUpdate() {
HashMap<String, Object> modifiedFields = getModifiedFields();
if (modifiedFields == null || modifiedFields.isEmpty()) {
return null;
}
StringBuilder fieldsToSet = new StringBuilder();
for (String field : modifiedFields.keySet()) {
fieldsToSet.append(field).append(" = :").append(field).append(" and ");
}
fieldsToSet.setLength(fieldsToSet.length() - 4);
return "UPDATE "
+ classType.getSimpleName()
+ " SET "
+ fieldsToSet
+ "WHERE "
+ primaryKey.getKey() + " = " + primaryKey.getValue();
}
private Field getPrimaryKeyField() throws ProxyInstantiationException {
for (Field field : classType.getDeclaredFields()) {
field.setAccessible(true);
if (field.isAnnotationPresent(Id.class))
return field;
}
throw new ProxyInstantiationException("Entity class doesn't have a primary key!");
}
}
And the exception class -
public class ProxyInstantiationException extends RuntimeException {
public ProxyInstantiationException(String message) {
super(message);
}
A service to save using this proxy -
@Service
public class PersistenceService {
@PersistenceContext
private EntityManager em;
@Transactional
private void save(Object entity) {
// update entity for proxies
if (entity instanceof EnhancedProxy) {
EnhancedProxy proxy = (EnhancedProxy) entity;
Query updateQuery = em.createQuery(proxy.getJPQLUpdate());
for (Entry<String, Object> entry : proxy.getModifiedFields().entrySet()) {
updateQuery.setParameter(entry.getKey(), entry.getValue());
}
updateQuery.executeUpdate();
// insert otherwise
} else {
em.persist(entity);
}
}
}
Note that the answer provided by ViNce does NOT include the end date for the period.
If you are using PHP 5.3+, your best bet is to use a function like this:
/**
* Generate an array of string dates between 2 dates
*
* @param string $start Start date
* @param string $end End date
* @param string $format Output format (Default: Y-m-d)
*
* @return array
*/
function getDatesFromRange($start, $end, $format = 'Y-m-d') {
$array = array();
$interval = new DateInterval('P1D');
$realEnd = new DateTime($end);
$realEnd->add($interval);
$period = new DatePeriod(new DateTime($start), $interval, $realEnd);
foreach($period as $date) {
$array[] = $date->format($format);
}
return $array;
}
Then, you would call the function as expected:
getDatesFromRange('2010-10-01', '2010-10-05');
Note about DatePeriod
class: You can use the 4th parameter of DatePeriod to exclude the start date (DatePeriod::EXCLUDE_START_DATE
) but you cannot, at this time, include the end date.
They are functionally equivalent, but INNER JOIN
can be a bit clearer to read, especially if the query has other join types (i.e. LEFT
or RIGHT
or CROSS
) included in it.
If none of those answers are working for you, try this. Add a submit button before the one that actually submits the form and just do nothing with the event.
HTML
<!-- The following button is meant to do nothing. This button will catch the "enter" key press and stop it's propagation. -->
<button type="submit" id="EnterKeyIntercepter" style="cursor: auto; outline: transparent;"></button>
JavaScript
$('#EnterKeyIntercepter').click((event) => {
event.preventDefault(); //The buck stops here.
/*If you don't know what this if statement does, just delete it.*/
if (process.env.NODE_ENV !== 'production') {
console.log("The enter key was pressed and captured by the mighty Enter Key Inceptor (¬¦_¦)");
}
});
The Pixastic library does exactly what you want. However, it will only work on browsers that have canvas support. For those older browsers, you'll either need to:
Of course, option #2 isn't very user-friendly. However, if your intent is to provide a pure client-only tool and/or you can't support a fallback back-end cropper (e.g. maybe you're writing a browser extension or offline Chrome app, or maybe you can't afford a decent hosting provider that provides image manipulation libraries), then it's probably fair to limit your user base to modern browsers.
EDIT: If you don't want to learn Pixastic, I have added a very simple cropper on jsFiddle here. It should be possible to modify and integrate and use the drawCroppedImage
function with Jcrop.
For get response in JSON format :
1.$response = (string) $res->getBody();
$response =json_decode($response); // Using this you can access any key like below
$key_value = $response->key_name; //access key
2. $response = json_decode($res->getBody(),true);
$key_value = $response['key_name'];//access key
Just write:
private static double balance = 0;
and you could also write those like that:
private static int id = 0;
private static double annualInterestRate = 0;
public static java.util.Date dateCreated;

To integrate the previous answers, there's an obvious advantage in declaring constant variables, apart from the performance reason: if you accidentally try to change or re-declare them in the code, the program will respectively not change the value or throw an error.
For example, compare:
// Will output 'SECRET'
const x = 'SECRET'
if (x = 'ANOTHER_SECRET') { // Warning! assigning a value variable in an if condition
console.log (x)
}
with:
// Will output 'ANOTHER_SECRET'
var y = 'SECRET'
if (y = 'ANOTHER_SECRET') {
console.log (y)
}
or
// Will throw TypeError: const 'x' has already been declared
const x = "SECRET"
/* complex code */
var x = 0
with
// Will reassign y and cause trouble
var y = "SECRET"
/* complex code */
var y = 0
You can use a session object. It stores the cookies so you can make requests, and it handles the cookies for you
s = requests.Session()
# all cookies received will be stored in the session object
s.post('http://www...',data=payload)
s.get('http://www...')
Docs: https://requests.readthedocs.io/en/master/user/advanced/#session-objects
You can also save the cookie data to an external file, and then reload them to keep session persistent without having to login every time you run the script:
The function I use currently:
/**

serialize: function(el) {
var serialized = $(el).serialize();
if (!serialized) // not a form
serialized = $(el).
find('input[name],select[name],textarea[name]').serialize();
return serialized;
}
I was using salesforce apex classes with Eclipse Neon 3.3 for Java.
I found an option "define folding region" on right click in the editor, I selected the block of code i wanted to collapse and selected this property for that code. Now I am seeing + and - symbol to expand and collapse that block of code
ALTER TABLE Protocols
ADD ProtocolTypeID int NOT NULL DEFAULT(1)
GO
The inclusion of the DEFAULT fills the column in existing rows with the default value, so the NOT NULL constraint is not violated.
Yes.
KVO requires dynamic dispatch, so you simply need to add the dynamic
modifier to a method, property, subscript, or initializer:
dynamic var foo = 0
The dynamic
modifier ensures that references to the declaration will be dynamically dispatched and accessed through objc_msgSend
.
Setting window full height for empty divs
1st solution with absolute positioning - FIDDLE
.div1 {
position: absolute;
top: 0;
bottom: 0;
width: 25%;
}
.div2 {
position: absolute;
top: 0;
left: 25%;
bottom: 0;
width: 75%;
}
2nd solution with static (also can be used a relative) positioning & jQuery - FIDDLE
.div1 {
float: left;
width: 25%;
}
.div2 {
float: left;
width: 75%;
}
$(function(){
$('.div1, .div2').css({ height: $(window).innerHeight() });
$(window).resize(function(){
$('.div1, .div2').css({ height: $(window).innerHeight() });
});
});
The process for timing out an operations is described in the documentation for signal.
The basic idea is to use signal handlers to set an alarm for some time interval and raise an exception once that timer expires.
Note that this will only work on UNIX.
Here's an implementation that creates a decorator (save the following code as timeout.py
).
from functools import wraps
import errno
import os
import signal
class TimeoutError(Exception):
pass
def timeout(seconds=10, error_message=os.strerror(errno.ETIME)):
def decorator(func):
def _handle_timeout(signum, frame):
raise TimeoutError(error_message)
def wrapper(*args, **kwargs):
signal.signal(signal.SIGALRM, _handle_timeout)
signal.alarm(seconds)
try:
result = func(*args, **kwargs)
finally:
signal.alarm(0)
return result
return wraps(func)(wrapper)
return decorator
This creates a decorator called @timeout
that can be applied to any long running functions.
So, in your application code, you can use the decorator like so:
from timeout import timeout
# Timeout a long running function with the default expiry of 10 seconds.
@timeout
def long_running_function1():
...
# Timeout after 5 seconds
@timeout(5)
def long_running_function2():
...
# Timeout after 30 seconds, with the error "Connection timed out"
@timeout(30, os.strerror(errno.ETIMEDOUT))
def long_running_function3():
...
Above are great answers. Here is an easy way to remember this:
a is a pointer
*a is the value
Now if you say "const a" then the pointer is const. (i.e. char * const a;)
If you say "const *a" then the value is const. (i.e. const char * a;)
An object can't be null - the value of an expression can be null. It's worth making the difference clear in your mind. The value of s
isn't an object - it's a reference, which is either null or refers to an object.
And yes, you should just use
if (s == null)
Note that this will still use the overloaded == operator defined in string, but that will do the right thing.
One possible cause of this is that your application expects to run on port 443 (standard SSL port) and port 443 is already in use. I have run into this several times with developers trying to run our application while Skype is running on their computers.
Incredibly, Skype runs on port 443. This is a horrible design flaw in my opinion. If you see your application trying to run on 444 instead of 443, shut down Skype and the problem will go away.
try running tor service, add the following function to your code.
def connect_tor(port):
socks.set_default_proxy(socks.PROXY_TYPE_SOCKS5, '127.0.0.1', port, True)
socket.socket = socks.socksocket
def main():
connect_tor()
driver = webdriver.Firefox()
Going forward, for graphical elements that are purely decorative, the best solution is to use:
android:importantForAccessibility="no"
This makes sense if your min SDK version is at least 16, since devices running lower versions will ignore this attribute.
If you're stuck supporting older versions, you should use (like others pointed out already):
android:contentDescription="@null"
Source: https://developer.android.com/guide/topics/ui/accessibility/apps#label-elements
A simpler way which eliminates checking if the app can open the url.
loadInBrowser = () => {
Linking.openURL(this.state.url).catch(err => console.error("Couldn't load page", err));
};
Calling it with a button.
<Button title="Open in Browser" onPress={this.loadInBrowser} />
New service updated to use the HttpClientModule and RxJS v5.5.x:
import { Injectable } from '@angular/core';
import { HttpClient, HttpErrorResponse } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import { catchError, tap } from 'rxjs/operators';
import { SomeClassOrInterface} from './interfaces';
import 'rxjs/add/observable/throw';
@Injectable()
export class MyService {
url = 'http://my_url';
constructor(private _http:HttpClient) {}
private handleError(operation: String) {
return (err: any) => {
let errMsg = `error in ${operation}() retrieving ${this.url}`;
console.log(`${errMsg}:`, err)
if(err instanceof HttpErrorResponse) {
// you could extract more info about the error if you want, e.g.:
console.log(`status: ${err.status}, ${err.statusText}`);
// errMsg = ...
}
return Observable.throw(errMsg);
}
}
// public API
public getData() : Observable<SomeClassOrInterface> {
// HttpClient.get() returns the body of the response as an untyped JSON object.
// We specify the type as SomeClassOrInterfaceto get a typed result.
return this._http.get<SomeClassOrInterface>(this.url)
.pipe(
tap(data => console.log('server data:', data)),
catchError(this.handleError('getData'))
);
}
Old service, which uses the deprecated HttpModule:
import {Injectable} from 'angular2/core';
import {Http, Response, Request} from 'angular2/http';
import {Observable} from 'rxjs/Observable';
import 'rxjs/add/observable/throw';
//import 'rxjs/Rx'; // use this line if you want to be lazy, otherwise:
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/do'; // debug
import 'rxjs/add/operator/catch';
@Injectable()
export class MyService {
constructor(private _http:Http) {}
private _serverError(err: any) {
console.log('sever error:', err); // debug
if(err instanceof Response) {
return Observable.throw(err.json().error || 'backend server error');
// if you're using lite-server, use the following line
// instead of the line above:
//return Observable.throw(err.text() || 'backend server error');
}
return Observable.throw(err || 'backend server error');
}
private _request = new Request({
method: "GET",
// change url to "./data/data.junk" to generate an error
url: "./data/data.json"
});
// public API
public getData() {
return this._http.request(this._request)
// modify file data.json to contain invalid JSON to have .json() raise an error
.map(res => res.json()) // could raise an error if invalid JSON
.do(data => console.log('server data:', data)) // debug
.catch(this._serverError);
}
}
I use .do()
(now .tap()
) for debugging.
When there is a server error, the body
of the Response
object I get from the server I'm using (lite-server) contains just text, hence the reason I use err.text()
above rather than err.json().error
. You may need to adjust that line for your server.
If res.json()
raises an error because it could not parse the JSON data, _serverError
will not get a Response
object, hence the reason for the instanceof
check.
In this plunker, change url
to ./data/data.junk
to generate an error.
Users of either service should have code that can handle the error:
@Component({
selector: 'my-app',
template: '<div>{{data}}</div>
<div>{{errorMsg}}</div>`
})
export class AppComponent {
errorMsg: string;
constructor(private _myService: MyService ) {}
ngOnInit() {
this._myService.getData()
.subscribe(
data => this.data = data,
err => this.errorMsg = <any>err
);
}
}
If you're using SQL Server 2008 it has this built in now, see this in books online
CAST(GETDATE() AS date)
If you code on Laravel just use Illuminate\Support\Str
here is example
Str::words($category->publication->title, env('WORDS_COUNT_HOME'), '...')

Unutbu answer is correct. But because our mean can be more or less than zero I would still like to change this :
x = np.linspace(-3 * sigma, 3 * sigma, 100)
to this :
x = np.linspace(-3 * sigma + mean, 3 * sigma + mean, 100)
Coarse-grained: A few ojects hold a lot of related data that's why services have broader scope in functionality. Example: A single "Account" object holds the customer name, address, account balance, opening date, last change date, etc. Thus: Increased design complexity, smaller number of cells to various operations
Fine-grained: More objects each holding less data that's why services have more narrow scope in functionality. Example: An Account object holds balance, a Customer object holds name and address, a AccountOpenings object holds opening date, etc. Thus: Decreased design complexity , higher number of cells to various service operations. These are relationships defined between these objects.
For the JS, try
data: {id: the_id}
...
success: function(data) {
alert('the server returned ' + data;
}
and
$the_id = intval($_POST['id']);
in PHP
You're thinking too complicated. It's actually just $('#'+openaddress)
.
I had the same issue on 14.04 with docker 1.9.1.
The upstart service command did work when I used sudo, even though I was root:
$ whoami
root
$ service docker status
status: Unbekannter Auftrag: docker
$ sudo service docker status
docker start/running, process 7394
It seems to depend on the environment variables.
service docker status
works when becoming root with su -
, but not when only using su
:
$ su
Password:
$ service docker status
status: unknown job: docker
$ exit
$ su -
Password:
$ service docker status
docker start/running, process 2342
Have a look here -- to query a sub-element of an element:
$(document.getElementById('parentid')).find('div#' + divID + ' span.child');
I solved the same importing problem reinstalling to seaborn package with
conda install -c https://conda.anaconda.org/anaconda seaborn
by typing the command on a Windows command console Afterwards I could then import seaborn successfully when I launched the IPython Notebook via on Anaconda launcher.
On the other failed way launching the IPython Notebook via Anaconda folder did not work for me.
On MySQL 5.7.x you need to switch to native password to be able to change it, like:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'test';
The following command may help you..
EXEC sp_configure 'show advanced options', 1
RECONFIGURE
GO
EXEC sp_configure 'ad hoc distributed queries', 1
RECONFIGURE
GO
