There are many ways to create re-usable objects like this in JavaScript. Mozilla have a nice introduction here:
The following will work in your example:
function Foo(){
this.bar = function (){
alert("Hello World!");
}
}
myFoo = new Foo();
myFoo.bar(); // Hello World?????????????????????????????????
I think you should avoid camel caps. The norm is to use lower case letters. I would also avoid underscores and use dashes instead
So your URL should look like this (ignoring the design issues as you requested :-))
api.service.com/hello-world/user-id/x
You can use guide=FALSE
in scale_..._...()
to suppress legend.
For your example you should use scale_colour_continuous()
because length
is continuous variable (not discrete).
(p3 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
scale_colour_continuous(guide = FALSE) +
geom_point()
)
Or using function guides()
you should set FALSE
for that element/aesthetic that you don't want to appear as legend, for example, fill
, shape
, colour
.
p0 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
geom_point()
p0+guides(colour=FALSE)
Both provided solutions work in new ggplot2
version 2.0.0 but movies
dataset is no longer present in this library. Instead you have to use new package ggplot2movies
to check those solutions.
library(ggplot2movies)
data(movies)
mov <- subset(movies, length != "")
This Message is also possible to pop up, if there is a typo in the fields on which you define a join
You have to add at least one file to the repository before committing, e.g. .gitignore
.
you can put your json in a parameter and send it instead of put only your json in header:
$post_string= 'json_param=' . json_encode($data);
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $post_string);
curl_setopt($curl, CURLOPT_URL, 'http://webservice.local/'); // Set the url path we want to call
//execute post
$result = curl_exec($curl);
//see the results
$json=json_decode($result,true);
curl_close($curl);
print_r($json);
on the service side you can get your json string as a parameter:
$json_string = $_POST['json_param'];
$obj = json_decode($json_string);
then you can use your converted data as object.

You need to enable SQL Server Authentication:
In my case, database returned latin1
, when my browser expected utf8
.
So for MySQLi I did:
mysqli_set_charset($dblink, "utf8");
See http://php.net/manual/en/mysqli.set-charset.php for more info
You could use a Dictionary<TKey, List<TValue>>
.
That would allow each key to reference a list of values.
Try this :
<script type="text/javascript">

To tell from the style of your code snippet, I suppose you were using IPython rather than Jupyter Notebook.
In this issue on GitHub, it was made clear by a member of IPython in 2016 that the display of charts would only work when "only work when it's a Jupyter kernel". Thus, the %matplotlib inline
would not work.
I was just having the same issue and suggest you use Jupyter Notebook for the visualization.
Even though is not the fastest choice, if performance is not an issue you can use:
sum(~np.isnan(data))
.
In [7]: %timeit data.size - np.count_nonzero(np.isnan(data))
10 loops, best of 3: 67.5 ms per loop
In [8]: %timeit sum(~np.isnan(data))
10 loops, best of 3: 154 ms per loop
In [9]: %timeit np.sum(~np.isnan(data))
10 loops, best of 3: 140 ms per loop
I have this function in my code base, this should work for you.
public static Document loadXMLFromString(String xml) throws Exception
{
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
InputSource is = new InputSource(new StringReader(xml));
return builder.parse(is);

I vote for Karthik T's answer. you don't need to open a terminal to run commands.
For example,
// file: RunShellCommandFromJava.java
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class RunShellCommandFromJava {
public static void main(String[] args) {
String command = "ping -c 3 www.google.com";
Process proc = Runtime.getRuntime().exec(command);
// Read the output
BufferedReader reader =
new BufferedReader(new InputStreamReader(proc.getInputStream()));
String line = "";
while((line = reader.readLine()) != null) {
System.out.print(line + "\n");
}
proc.waitFor();
}
}
The output:

Baron Schwartz blogs that due to race conditions, this 'check before write' is a bad practice. He advocates a try/catch pattern with a reconnect
in the catch. Here is the pseudo code he recommends:
function query_database(connection, sql, retries=1)
while true
try
result=connection.execute(sql)
return result
catch InactiveConnectionException e
if retries > 0 then
retries = retries - 1
connection.reconnect()
else
throw e
end
end
end
end

The other answers did not address my need for properly showing tooltips in a recent version of Jupyter inline matplotlib figure. This one works though:
import matplotlib.pyplot as plt
import numpy as np
import mplcursors
np.random.seed(42)
fig, ax = plt.subplots()
ax.scatter(*np.random.random((2, 26)))
ax.set_title("Mouse over a point")
crs = mplcursors.cursor(ax,hover=True)
crs.connect("add", lambda sel: sel.annotation.set_text(
'Point {},{}'.format(sel.target[0], sel.target[1])))
plt.show()
Leading to something like the following picture when going over a point with mouse:
For make a list, simply do that
colors=(red orange white "light gray")
Technically is an array, but - of course - it has all list features.
Even python list are implemented with array
You need to escape the quotes in the string by adding a backslash \
before "
.
Like:
"<font color=\"red\">"
This can also happen when the log file is restricted in size.
Right click database in Object Explorer
Select Properties
Select Files
On the log line, click the ellipsis in the Autogrowth / Maxsize column
Change/verify Maximum File Size is Unlimited.
After chaning to unlimited, database came back to life.
This issue is because of you having some local or private packages.
For accessing those packages you have to create .npmrc
file for this issue. Just refer the following link for your solution. https://nodesource.com/blog/configuring-your-npmrc-for-an-optimal-node-js-environment
AFAIK you will need at least a little bit of JavaScript...
I would suggest to use jQuery.
You can include this library in one line. And then you can access your div with
$('div').click(function(){
// do stuff here
});
and respond to the click event.
Using a single Awk:
... | awk -F '[/:]' '{print $5}'
That is, using as field separator either /
or :
, the username is always in field 5.
To store it in a variable:
username=$(... | awk -F '[/:]' '{print $5}')
A more flexible implementation with sed
that doesn't require username to be field 5:
... | sed -e s/:.*// -e s?.*/??
That is, delete everything from :
and beyond, and then delete everything up until the last /
. sed
is probably faster too than awk
, so this alternative is definitely better.
Here is another quick approach without using additional panel.
JFrame f = new JFrame("stackoverflow") {
private Image backgroundImage = ImageIO.read(new File("background.jpg"));
public void paint( Graphics g ) {
super.paint(g);
g.drawImage(backgroundImage, 0, 0, null);
}
};
You should probably check for errors in /var/log/nginx/error.log
.
In my case I did no add the port for ipv6. You should also do this (in case you are running nginx on a port other than 80):
listen [::]:8000 default_server ipv6only=on;
Can change the text colour by overriding the getView method as follows:
new ArrayAdapter<String>(getContext(), android.R.layout.simple_spinner_dropdown_item, list()){
@Override
public View getView(int position, View convertView, @NonNull ViewGroup parent) {
View view = super.getView(position, convertView, parent);
//change the color to which ever you want
((CheckedTextView) view).setTextColor(Color.RED);
//change the size to which ever you want
((CheckedTextView) view).setTextSize(5);
//for using sp values use setTextSize(TypedValue.COMPLEX_UNIT_SP, 16);
return view;
}
}
Simply put, numpy.newaxis
is used to increase the dimension of the existing array by one more dimension, when used once. Thus,
1D array will become 2D array
2D array will become 3D array
3D array will become 4D array
4D array will become 5D array
and so on..
Here is a visual illustration which depicts promotion of 1D array to 2D arrays.
Scenario-1: np.newaxis
might come in handy when you want to explicitly convert a 1D array to either a row vector or a column vector, as depicted in the above picture.
Example:
# 1D array
In [7]: arr = np.arange(4)
In [8]: arr.shape
Out[8]: (4,)
# make it as row vector by inserting an axis along first dimension
In [9]: row_vec = arr[np.newaxis, :] # arr[None, :]
In [10]: row_vec.shape
Out[10]: (1, 4)
# make it as column vector by inserting an axis along second dimension
In [11]: col_vec = arr[:, np.newaxis] # arr[:, None]
In [12]: col_vec.shape
Out[12]: (4, 1)
Scenario-2: When we want to make use of numpy broadcasting as part of some operation, for instance while doing addition of some arrays.
Example:
Let's say you want to add the following two arrays:
x1 = np.array([1, 2, 3, 4, 5])
x2 = np.array([5, 4, 3])
If you try to add these just like that, NumPy will raise the following ValueError
:
ValueError: operands could not be broadcast together with shapes (5,) (3,)
In this situation, you can use np.newaxis
to increase the dimension of one of the arrays so that NumPy can broadcast.
In [2]: x1_new = x1[:, np.newaxis] # x1[:, None]
# now, the shape of x1_new is (5, 1)
# array([[1],
# [2],
# [3],
# [4],
# [5]])
Now, add:
In [3]: x1_new + x2
Out[3]:
array([[ 6, 5, 4],
[ 7, 6, 5],
[ 8, 7, 6],
[ 9, 8, 7],
[10, 9, 8]])
Alternatively, you can also add new axis to the array x2
:
In [6]: x2_new = x2[:, np.newaxis] # x2[:, None]
In [7]: x2_new # shape is (3, 1)
Out[7]:
array([[5],
[4],
[3]])
Now, add:
In [8]: x1 + x2_new
Out[8]:
array([[ 6, 7, 8, 9, 10],
[ 5, 6, 7, 8, 9],
[ 4, 5, 6, 7, 8]])
Note: Observe that we get the same result in both cases (but one being the transpose of the other).
Scenario-3: This is similar to scenario-1. But, you can use np.newaxis
more than once to promote the array to higher dimensions. Such an operation is sometimes needed for higher order arrays (i.e. Tensors).
Example:
In [124]: arr = np.arange(5*5).reshape(5,5)
In [125]: arr.shape
Out[125]: (5, 5)
# promoting 2D array to a 5D array
In [126]: arr_5D = arr[np.newaxis, ..., np.newaxis, np.newaxis] # arr[None, ..., None, None]
In [127]: arr_5D.shape
Out[127]: (1, 5, 5, 1, 1)
As an alternative, you can use numpy.expand_dims
that has an intuitive axis
kwarg.
# adding new axes at 1st, 4th, and last dimension of the resulting array
In [131]: newaxes = (0, 3, -1)
In [132]: arr_5D = np.expand_dims(arr, axis=newaxes)
In [133]: arr_5D.shape
Out[133]: (1, 5, 5, 1, 1)
More background on np.newaxis vs np.reshape
newaxis
is also called as a pseudo-index that allows the temporary addition of an axis into a multiarray.
np.newaxis
uses the slicing operator to recreate the array while numpy.reshape
reshapes the array to the desired layout (assuming that the dimensions match; And this is must for a reshape
to happen).
Example
In [13]: A = np.ones((3,4,5,6))
In [14]: B = np.ones((4,6))
In [15]: (A + B[:, np.newaxis, :]).shape # B[:, None, :]
Out[15]: (3, 4, 5, 6)
In the above example, we inserted a temporary axis between the first and second axes of B
(to use broadcasting). A missing axis is filled-in here using np.newaxis
to make the broadcasting operation work.
General Tip: You can also use None
in place of np.newaxis
; These are in fact the same objects.
In [13]: np.newaxis is None
Out[13]: True
P.S. Also see this great answer: newaxis vs reshape to add dimensions
Try:
pwd=`pwd`
or
pwd=$(pwd)
Notice no spaces after the equals sign.
Also as Mr. Weiss points out; you don't assign to $pwd
, you assign to pwd
.
In cases where you just want to inject some styles from a stylesheet into a component without bundling in the whole stylesheet I recommend https://github.com/glortho/styled-import. For example:
const btnStyle = styledImport.react('../App.css', '.button')
// btnStyle is now { color: 'blue' } or whatever other rules you have in `.button`.
NOTE: I am the author of this lib, and I built it for cases where mass imports of styles and CSS modules are not the best or most viable solution.
var $form_elements = $("#form_id").find(":input");
All the elements including the submit-button are now in the variable $form_elements.
Its too late, but it may be simple and useful
var json = { "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" };
var keytoFind = "key2";
var index = Object.keys(json).indexOf(keytoFind);
alert(index);
How about calling a function from within your callback instead of returning a value in sync_call()?
function sync_call(input) {
var value;
// Assume the async call always succeed
async_call(input, function(result) {
value = result;
use_value(value);
} );
}
You can use substring
from String.class
(handling exceptions) or from Apache lang commons (it handles exceptions for you)
static String substring(String str, int start, int end)
Put it inside a loop and you are good to go.
As guruz mentioned, the JIT has several lovely graph/tree layouts, including quite appealing RGraph and HyperTree visualizations.
Also, I've just put up a super simple SVG-based implementation at github (no dependencies, ~125 LOC) that should work well enough for small graphs displayed in modern browsers.
It is a broken/very hard to use replacement for the "center" tag. It comes in handy when you need broken tables and non-working centering for blocks and text.
//first: Create a class as your view model
public class EventViewModel
{
public int Id{get;set}
public string Property1{get;set;}
public string Property2{get;set;}
}
//then from your method
[HttpGet]
public async Task<ActionResult> GetEvent()
{
var events = await db.Event.Find(x => x.ID != 0);
List<EventViewModel> model = events.Select(event => new EventViewModel(){
Id = event.Id,
Property1 = event.Property1,
Property1 = event.Property2
}).ToList();
return Json(new{ data = model }, JsonRequestBehavior.AllowGet);
}
Running an intent service will be easier. Service in creating a thread in the application but it's still in the application.
Run: python -c "import ssl; print(ssl.get_default_verify_paths())"
to check the current paths which are used to verify the certificate. Add your company's root certificate to one of those.
The path openssl_capath_env
points to the environment variable: SSL_CERT_DIR
.
If SSL_CERT_DIR
doesn't exist, you will need to create it and point it to a valid folder within your filesystem. You can then add your certificate to this folder to use it.
The standard text editor in windows is notepad. There are no built-in command line editors.
Windows does not ship a C or C++ compiler. The .NET framework comes with several compilers, though: csc.exe
(C# compiler), vbc.exe
(VB.NET compiler), jsc.exe
(JavaScript compiler).
If you want a free alternative you can download Visual Studio Express 2013 for Windows Desktop that comes with an optimizing C/C++ compiler (cl.exe
).
It's all in your things.size()
type. It isn't int
, but size_t
(it exists in C++, not in C) which equals to some "usual" unsigned type, i.e. unsigned int
for x86_32.
Operator "less" (<) cannot be applied to two operands of different sign. There's just no such opcodes, and standard doesn't specify, whether compiler can make implicit sign conversion. So it just treats signed number as unsigned and emits that warning.
It would be correct to write it like
for (size_t i = 0; i < things.size(); ++i) { /**/ }
or even faster
for (size_t i = 0, ilen = things.size(); i < ilen; ++i) { /**/ }
Your @POST
method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:
@XmlRootElement
public class MyJaxBean {
@XmlElement public String param1;
@XmlElement public String param2;
}
Then your @POST
method would look like the following:
@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
System.out.println("param1 = " + input.param1);
System.out.println("param2 = " + input.param2);
}
This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input
in this case. The actual message would look something like:
POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com
{"param1":"hello","param2":"world"}
Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.
HTML <FORM>
The parameters would be annotated using @FormParam:
@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
@FormParam("param2") String param2) {
...
}
The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:
POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25
param1=hello¶m2=world
The content is URL encoded in this case.
If you do not know the names of the FormParam's you can do the following:
@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
...
}
HTTP Headers
You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:
@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
@HeaderParam("param2") String param2) {
...
}
Here's what the HTTP message would look like. Note that this POST does not have a body.
POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world
I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.
HTTP Query Parameters
This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.
@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
@QueryParam("param2") String param2) {
...
}
Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:
POST /create?param1=hello¶m2=world HTTP/1.1
Content-Length: 0
Host: www.example.com
You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.
HTTP Path Parameters
Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:
@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
@PathParam("param2") String param2) {
...
}
The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.
POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com
This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.
As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM
-based HTML pages, then use @FormParam
. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer
implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM
encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.
Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.
The string contains that string all the time when looping through it. You don't want to ++ because what this is doing right now is just getting the length of the string if it contains " "male cat"
You need to indexOf() / substring()
Kind of get what i am saying?
If you try to use "ModelState.Remove" or "ModelState["Prop"].Errors.Clear()" the "ModelState.IsValid" stil returns false.
Why not just removing the default "Required" Annotation from Model and make your custom validation before the "ModelState.IsValid" on Controller 'Post' action? Like this:
if (!String.IsNullOrEmpty(yourClass.Property1) && String.IsNullOrEmpty(yourClass.dependantProperty))
ModelState.AddModelError("dependantProperty", "It´s necessary to select some 'dependant'.");
LogisticRegression
is not for regression but classification !
The Y
variable must be the classification class,
(for example 0
or 1
)
And not a continuous
variable,
that would be a regression problem.
You could do it this way:
-- Notice how STATE got moved inside the condition:
CASE WHEN STATE = 2 AND RetailerProcessType IN (1, 2) THEN '"AUTHORISED"'
WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
ELSE '"DECLINED"'
END
The reason you can do an AND
here is that you are not checking the CASE
of STATE
, but instead you are CASING Conditions.
The key part here is that the STATE
condition is a part of the WHEN
.
Alternatively to the answer marked as correct, if you have to replace words instead of chars you can do it with this piece of code :
$query = "INSERT INTO my_table VALUES (?, ?, ?, ?);";
$values = Array("apple", "oranges", "mangos", "papayas");
foreach (array_fill(0, count($values), '?') as $key => $wildcard) {
$query = substr_replace($query, '"'.$values[$key].'"', strpos($query, $wildcard), strlen($wildcard));
}
echo $query;

For the benefit of others, I though I'd include what I did.
Since you cannot get Visual Studio (2010 in my case) to ignore the LNK4204 warnings, my approach was to give it what it wanted: the pdb files. As I was using open source libraries in my case, I have the code building the pdb files already.
BUT, the default is to name all of the PDF files the same thing: vc100.pdb in my case. As you need a .pdb for each and every .lib, this creates a problem, especially if you are using something like ImageMagik, which creates about 20 static .lib files. You cannot have 20 lib files in one directory (which your application's linker references to link in the libraries from) and have all the 20 .pdb files called the same thing.
My solution was to go and rebuild my static library files, and configure VS2010 to name the .pdb file with respect to the PROJECT. This way, each .lib gets a similarly named .pdb, and you can put all of the LIBs and PDBs in one directory for your project to use.
So for the "Debug" configuraton, I edited:
Properties->Configuration Properties -> C/C++ -> Output Files -> Program Database File Name from
$(IntDir)vc$(PlatformToolsetVersion).pdb
to be the following value:
$(OutDir)vc$(PlatformToolsetVersion)D$(ProjectName).pdb
Now rather than somewhere in the intermediate directory, the .pdb files are written to the output directory, where the .lib files are also being written, AND most importantly, they are named with a suffix of D+project name. This means each library project produduces a project .lib and a project specific .pdb.
I'm now able to copy all of my release .lib files, my debug .lib files and the debug .pdb files into one place on my development system, and the project that uses that 3rd party library in debug mode, has the pdb files it needs in debug mode.

A more smart injection target could be done with this code :
/*
* For all links in the current page...
*/
$(document.links).filter(function() {
/*
* ...keep them without `target` already setted...
*/
return !this.target;
}).filter(function() {
/*
* ...and keep them are not on current domain...
*/
return this.hostname !== window.location.hostname ||
/*
* ...or are not a web file (.pdf, .jpg, .png, .js, .mp4, etc.).
*/
/\.(?!html?|php3?|aspx?)([a-z]{0,3}|[a-zt]{0,4})$/.test(this.pathname);
/*
* For all link kept, add the `target="_blank"` attribute.
*/
}).attr('target', '_blank');
You could change the regexp exceptions with adding more extension in (?!html?|php3?|aspx?)
group construct (understand this regexp here: https://regex101.com/r/sE6gT9/3).
and for a without jQuery version, check code below:
var links = document.links;
for (var i = 0; i < links.length; i++) {
if (!links[i].target) {
if (
links[i].hostname !== window.location.hostname ||
/\.(?!html?)([a-z]{0,3}|[a-zt]{0,4})$/.test(links[i].pathname)
) {
links[i].target = '_blank';
}
}
}
this code worked for me to re-instantiate the event after i had used :
event.preventDefault(); to disable the event.
event.preventDefault = false;

Warning: A component is changing an uncontrolled input of type text to be controlled. Input elements should not switch from uncontrolled to controlled (or vice versa). Decide between using a controlled or uncontrolled input element for the lifetime of the component.
Solution : Check if value is not undefined
React / Formik / Bootstrap / TypeScript
example :
{ values?.purchaseObligation.remainingYear ?
<Input
tag={Field}
name="purchaseObligation.remainingYear"
type="text"
component="input"
/> : null
}
Declare value attribute for input tag (i.e value= {this.state.name}
) and if you want to clear this input vale you have to use this.setState({name : ''})
PFB working code for your reference :
<script type="text/babel">
var StateComponent = React.createClass({
resetName : function(event){
this.setState({
name : ''
});
},
render : function(){
return (
<div>
<input type="text" value= {this.state.name}/>
<button onClick={this.resetName}>Reset</button>
</div>
)
}
});
ReactDOM.render(<StateComponent/>, document.getElementById('app'));

If you'd prefer a more direct approach, one that does NOT mess with symlinking between /etc/nginx/sites-available
and /etc/nginx/sites-enabled
, do the following:
/etc/nginx/nginx.conf
include /etc/nginx/conf.d/*.conf;
This tells nginx to pull in any files in the conf.d
directory that end in .conf
. (I know: it's weird that a directory can have a .
in it.)conf.d
directory if it doesn't already exist (per the path in step 3). Be sure to give it the right permissions/ownership. Likely root or www-data. /etc/nginx/sites-available
) into the directory conf.d
.Any .conf
files that you put into the conf.d
directory from here on out will become active as long as you reload/restart nginx after.
Note: You can use the conf.d
and sites-enabled
+ sites-available
method concurrently if you wish. I like to test on my dev box using conf.d
. Feels faster than symlinking and unsymlinking.
I believe the only way is to get a list from the iterator then get the element you want from that list.

If the forked repo is protected so you can't push directly into it, and your goal is to make changes to their foo, then you need to get their branch foo into your repo like so:
git remote add protected_repo https://github.com/theirusername/their_repo.git
git fetch protected_repo
git checkout --no-track protected_repo/foo
Now you have a local copy of foo with no upstream associated to it. You can commit changes to it (or not) and then push your foo to your own remote repo.
git push --set-upstream origin foo
Now foo is in your repo on GitHub and your local foo is tracking it. If they continue to make changes to foo you can fetch theirs and merge into your foo.
git checkout foo
git fetch protected_repo
git merge protected_repo/foo
I use SimpleJpaRepository as the base class of repository implementation and add custom method in the interface,eg:
public interface UserRepository {
User FindOrInsert(int userId);
}
@Repository
public class UserRepositoryImpl extends SimpleJpaRepository implements UserRepository {
private RedisClient redisClient;
public UserRepositoryImpl(RedisClient redisClient, EntityManager em) {
super(User.class, em);
this.redisClient = redisClient;
}
@Override
public User FindOrInsert(int userId) {
User u = redisClient.getOrSet("test key.. User.class, () -> {
Optional<User> ou = this.findById(Integer.valueOf(userId));
return ou.get();
});
…………
return u;
}
<p><input type="checkbox" name="ch1" checked="checked" /> First Name</p>
....
<td class="ch1">...</td>
<script>
$(document).ready(function() {
$('#demo').multiselect();
});
$("input:checkbox:not(:checked)").each(function() {
var column = "table ." + $(this).attr("name");
$(column).hide();
});
$("input:checkbox").click(function(){
var column = "table ." + $(this).attr("name");
$(column).toggle();
});

Am I missing something in the question or why else nobody mentioned reviver
parameter of JSON.parse
since 2011?
Here is simplistic code for solution that works: https://jsfiddle.net/Ldr2utrr/
function Foo()
{
this.a = 3;
this.b = 2;
this.test = function() {return this.a*this.b;};
}
var fooObj = new Foo();
alert(fooObj.test() ); //Prints 6
var fooJSON = JSON.parse(`{"a":4, "b": 3}`, function(key,value){
if(key!=="") return value; //logic of course should be more complex for handling nested objects etc.
let res = new Foo();
res.a = value.a;
res.b = value.b;
return res;
});
// Here you already get Foo object back
alert(fooJSON.test() ); //Prints 12
PS: Your question is confusing: >>That's great, but how can I take that JavaScript Object and turn it into a particular JavaScript Object (i.e. with a certain prototype)? contradicts to the title, where you ask about JSON parsing, but the quoted paragraph asks about JS runtime object prototype replacement.
IE11 does implement String.prototype.includes so why not using the official Polyfill?
if (!String.prototype.includes) {
String.prototype.includes = function(search, start) {
if (typeof start !== 'number') {
start = 0;
}
if (start + search.length > this.length) {
return false;
} else {
return this.indexOf(search, start) !== -1;
}
};
}

I like Jaco Pretorius' solution, but I wanted to make the "this" keyword a bit more useful by pointing it to the module/namespace object. My version of skillet:
(function ($, undefined) {
console.log(this);
}).call(window.myNamespace = window.myNamespace || {}, jQuery);
You can define multiple routes with and without parameter:
@RouteConfig([
{ path: '/user/:id', component: User, name: 'User' },
{ path: '/user', component: User, name: 'Usernew' }
])
and handle the optional parameter in your component:
constructor(params: RouteParams) {
var paramId = params.get("id");
if (paramId) {
...
}
}

Grep is useful if you want to quickly search for lines that match in a file. It can also return some other simple information like matching line numbers, match count, and file name lists.
Awk is an entire programming language built around reading CSV-style files, processing the records, and optionally printing out a result data set. It can do many things but it is not the easiest tool to use for simple tasks.
Sed is useful when you want to make changes to a file based on regular expressions. It allows you to easily match parts of lines, make modifications, and print out results. It's less expressive than awk but that lends it to somewhat easier use for simple tasks. It has many more complicated operators you can use (I think it's even turing complete), but in general you won't use those features.
A lot of the above answers are a bit out of date, so this is a quick summary for a more recent version of RSpec (3.8+). This solution raises no warnings from rubocop-rspec and is inline with rspec best practices:
A successful JSON response is identified by two things:
application/json
Assuming that the response object is the anonymous subject of the test, both of the above conditions can be validate using Rspec's built in matchers:
context 'when response is received' do
subject { response }
# check for a successful JSON response
it { is_expected.to have_attributes(content_type: include('application/json')) }
it { is_expected.to have_attributes(body: satisfy { |v| JSON.parse(v) }) }
# validates OP's condition
it { is_expected.to satisfy { |v| JSON.parse(v.body).key?('success') }
it { is_expected.to satisfy { |v| JSON.parse(v.body)['success'] == true }
end
If you're prepared to name your subject then the above tests can be simplified further:
context 'when response is received' do
subject(:response) { response }
it 'responds with a valid content type' do
expect(response.content_type).to include('application/json')
end
it 'responds with a valid json object' do
expect { JSON.parse(response.body) }.not_to raise_error
end
it 'validates OPs condition' do
expect(JSON.parse(response.body, symoblize_names: true))
.to include(success: true)
end
end
None of the other answers worked for me. After some tinkering I unsinstalled sklearn:
pip uninstall sklearn
Then I removed sklearn folder from here: (adjust the path to your system and python version)
C:\Users\%USERNAME%\AppData\Roaming\Python\Python36\site-packages
And the installed it from wheel from this site: link
The error was there probably because of a version conflict with sklearn installed somewhere else.
You could write a convenience method:
public PrintStream print(String format, Object... arguments) {
return System.out.format(format, arguments);
}
But as you can see, you've simply just renamed format
(or printf
).
Here's how you could use it:
private void printScores(Player... players) {
for (int i = 0; i < players.length; ++i) {
Player player = players[i];
String name = player.getName();
int score = player.getScore();
// Print name and score followed by a newline
System.out.format("%s: %d%n", name, score);
}
}
// Print a single player, 3 players, and all players
printScores(player1);
System.out.println();
printScores(player2, player3, player4);
System.out.println();
printScores(playersArray);
// Output
Abe: 11
Bob: 22
Cal: 33
Dan: 44
Abe: 11
Bob: 22
Cal: 33
Dan: 44
Note there's also the similar System.out.printf
method that behaves the same way, but if you peek at the implementation, printf
just calls format
, so you might as well use format
directly.
The code says everything:
max@serv$ chmod 777 .
Okay, it doesn't say everything.
In UNIX and Linux, the ability to remove a file is not determined by the access bits of that file. It is determined by the access bits of the directory which contains the file.
Think of it this way -- deleting a file doesn't modify that file. You aren't writing to the file, so why should "w" on the file matter? Deleting a file requires editing the directory that points to the file, so you need "w" on the that directory.
In the particular case you've provided, it's a conditional assignment. The part before the question mark (?) is a boolean condition, and the parts either side of the colon (:) are the values to assign based on the result of the condition (left side of the colon is the value for true, right side is the value for false).

Finally resolved my java install issue on Win 7 64-bit running IE11.
Even though I installed the latest Java (65) via a java auto-update prompt, tried a verify java version and java failed to run, shut down all IE instances, failed to run verify again, shut down all running programs, failed to run verify again, rebooted, failed to run verify again, re-installed 65 again (shutting down the browser manually as it downloaded), and finally verify ran. What a pain.
The message I kept receiving was "The page you are viewing uses Java ..."; e.g. https://www.java.com/en/download/help/ie_tips.xml. I do use sleep mode on my desktop and I believe that this is probably the major issue with install and IE with its "clever" integration into the OS and explorer/desktop. I thought the government told them to not do that. I've had issues with CD-ROM drive disappearing and other unexplained periodic issues; all cured after a full reboot. They are infrequent, so I live with them for the convenience of faster startup times.
Hope this helps someone!
Using following code, one can first check variable is set or not using @isset of laravel directive and then check that array is blank or not using @unless of laravel directive
@if(@isset($names))
@unless($names)
Array has no value
@else
Array has value
@foreach($names as $name)
{{$name}}
@endforeach
@endunless
@else
Not defined
@endif

Considering that you are using OpenCV, the best way to convert between data types is to use normalize
function.
img_n = cv2.normalize(src=img, dst=None, alpha=0, beta=255, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_8U)
However, if you don't want to use OpenCV, you can do this in numpy
def convert(img, target_type_min, target_type_max, target_type):
imin = img.min()
imax = img.max()
a = (target_type_max - target_type_min) / (imax - imin)
b = target_type_max - a * imax
new_img = (a * img + b).astype(target_type)
return new_img
And then use it like this
imgu8 = convert(img16u, 0, 255, np.uint8)
This is based on the answer that I found on crossvalidated board in comments under this solution https://stats.stackexchange.com/a/70808/277040
You want a multiple attribute selector
$("input[type='checkbox'][name='ProductCode']").each(function(){ ...
or
$("input:checkbox[name='ProductCode']").each(function(){ ...
It would be better to use a CSS class to identify those that you want to select however as a lot of the modern browsers implement the document.getElementsByClassName
method which will be used to select elements and be much faster than selecting by the name
attribute
These posts apparently are in the wrong order! This is #3 in a series of 3 posts. Sorry.
I've "taken a few MORE liberties" with Lie Ryan's code. The linked list admittedly was time-consuming to access individual elements due to search overhead, i.e. walking down the list until you find the right element. I have now cured this by maintaining an address vector containing subscripts 0 through whatever paired with memory addresses. This works because the address vector is allocated all-at-once, thus contiguous in memory. Since the linked-list is no longer required, I've ripped out its associated code and structure.
This approach is not quite as efficient as a plain-and-simple static array would be, but at least you don't have to "walk the list" searching for the proper item. You can now access the elements by using a subscript. To enable this, I have had to add code to handle cases where elements are removed and the "actual" subscripts wouldn't be reflected in the pointer vector's subscripts. This may or may not be important to users. For me, it IS important, so I've made re-numbering of subscripts optional. If renumbering is not used, program flow goes to a dummy "missing" element which returns an error code, which users can choose to ignore or to act on as required.
From here, I'd advise users to code the "elements" portion to fit their needs and make sure that it runs correctly. If your added elements are arrays, carefully code subroutines to access them, seeing as how there's extra array structure that wasn't needed with static arrays. Enjoy!

On modern browsers you can use wheel event
:
// Content is the element you want to apply the wheel scroll effect to
content.addEventListener('wheel', function(e) {
const step = 100; // How many pixels to scroll
if (e.deltaY > 0) // Scroll down
content.scrollTop += step;
else // Scroll up
content.scrollTop -= step;
});
This code will verify the json independently of param object order.
var isEqualsJson = (obj1,obj2)=>{
keys1 = Object.keys(obj1);
keys2 = Object.keys(obj2);
//return true when the two json has same length and all the properties has same value key by key
return keys1.length === keys2.length && Object.keys(obj1).every(key=>obj1[key]==obj2[key]);
}
var obj1 = {a:1,b:2,c:3};
var obj2 = {a:1,b:2,c:3};
console.log("json is equals: "+ isEqualsJson(obj1,obj2));
alert("json is equals: "+ isEqualsJson(obj1,obj2));

First you need to import the angular router :
import {Router} from "@angular/router"
Then inject it in your component constructor :
constructor(private router: Router) { }
And finally call the .navigate
method anywhere you need to "redirect" :
this.router.navigate(['/your-path'])
You can also put some parameters on your route, like user/5
:
this.router.navigate(['/user', 5])

This is what I've been using for development:
<?xml version="1.0" ?>
<cross-domain-policy>
<allow-access-from domain="*" />
</cross-domain-policy>
This is a very liberal approach, but is fine for my application.
As others have pointed out below, beware the risks of this.
If you want to read any created function, this how we do it:
<input type="button" value="sports" onClick="window.open('<?php sports();?>', '_self');">
Using Visual Studio
This gives details about each assembly, app domain and has a few options to load symbols (i.e. pdb files that contain debug information).
Using Process Explorer
If you want an external tool you can use the Process Explorer (freeware, published by Microsoft)
Click on a process and it will show a list with all the assemblies used. The tool is pretty good as it shows other information such as file handles etc.
Programmatically
Check this SO question that explains how to do it.
I never liked the way of asserting exceptions with Junit. If I use the "expected" in the annotation, seems from my point of view we're violating the "given, when, then" pattern because the "then" is placed at the top of the test definition.
Also, if we use "@Rule", we have to deal with so much boilerplate code. So, if you can install new libraries for your tests, I'd suggest to have a look to the AssertJ (that library now comes with SpringBoot)
Then a test which is not violating the "given/when/then" principles, and it is done using AssertJ to verify:
1 - The exception is what we're expecting. 2 - It has also an expected message
Will look like this:
@Test
void should_throwIllegalUse_when_idNotGiven() {
//when
final Throwable raisedException = catchThrowable(() -> getUserDAO.byId(null));
//then
assertThat(raisedException).isInstanceOf(IllegalArgumentException.class)
.hasMessageContaining("Id to fetch is mandatory");
}
I have had luck using the socket object directly (rather than the TCP client). I create a Server object that looks something like this (I've edited some stuff such as exception handling out for brevity, but I hope that the idea comes across.)...
public class Server()
{
private Socket sock;
// You'll probably want to initialize the port and address in the
// constructor, or via accessors, but to start your server listening
// on port 8080 and on any IP address available on the machine...
private int port = 8080;
private IPAddress addr = IPAddress.Any;
// This is the method that starts the server listening.
public void Start()
{
// Create the new socket on which we'll be listening.
this.sock = new Socket(
addr.AddressFamily,
SocketType.Stream,
ProtocolType.Tcp);
// Bind the socket to the address and port.
sock.Bind(new IPEndPoint(this.addr, this.port));
// Start listening.
this.sock.Listen(this.backlog);
// Set up the callback to be notified when somebody requests
// a new connection.
this.sock.BeginAccept(this.OnConnectRequest, sock);
}
// This is the method that is called when the socket recives a request
// for a new connection.
private void OnConnectRequest(IAsyncResult result)
{
// Get the socket (which should be this listener's socket) from
// the argument.
Socket sock = (Socket)result.AsyncState;
// Create a new client connection, using the primary socket to
// spawn a new socket.
Connection newConn = new Connection(sock.EndAccept(result));
// Tell the listener socket to start listening again.
sock.BeginAccept(this.OnConnectRequest, sock);
}
}
Then, I use a separate Connection class to manage the individual connection with the remote host. That looks something like this...
public class Connection()
{
private Socket sock;
// Pick whatever encoding works best for you. Just make sure the remote
// host is using the same encoding.
private Encoding encoding = Encoding.UTF8;
public Connection(Socket s)
{
this.sock = s;
// Start listening for incoming data. (If you want a multi-
// threaded service, you can start this method up in a separate
// thread.)
this.BeginReceive();
}
// Call this method to set this connection's socket up to receive data.
private void BeginReceive()
{
this.sock.BeginReceive(
this.dataRcvBuf, 0,
this.dataRcvBuf.Length,
SocketFlags.None,
new AsyncCallback(this.OnBytesReceived),
this);
}
// This is the method that is called whenever the socket receives
// incoming bytes.
protected void OnBytesReceived(IAsyncResult result)
{
// End the data receiving that the socket has done and get
// the number of bytes read.
int nBytesRec = this.sock.EndReceive(result);
// If no bytes were received, the connection is closed (at
// least as far as we're concerned).
if (nBytesRec <= 0)
{
this.sock.Close();
return;
}
// Convert the data we have to a string.
string strReceived = this.encoding.GetString(
this.dataRcvBuf, 0, nBytesRec);
// ...Now, do whatever works best with the string data.
// You could, for example, look at each character in the string
// one-at-a-time and check for characters like the "end of text"
// character ('\u0003') from a client indicating that they've finished
// sending the current message. It's totally up to you how you want
// the protocol to work.
// Whenever you decide the connection should be closed, call
// sock.Close() and don't call sock.BeginReceive() again. But as long
// as you want to keep processing incoming data...
// Set up again to get the next chunk of data.
this.sock.BeginReceive(
this.dataRcvBuf, 0,
this.dataRcvBuf.Length,
SocketFlags.None,
new AsyncCallback(this.OnBytesReceived),
this);
}
}
You can use your Connection object to send data by calling its Socket directly, like so...
this.sock.Send(this.encoding.GetBytes("Hello to you, remote host."));
As I said, I've tried to edit the code here for posting, so I apologize if there are any errors in it.

I personally use something like this (vertical tree traversal using recursion)
fun ViewGroup.deepForEach(function: View.() -> Unit) {
this.forEach { child ->
child.function()
if (child is ViewGroup) {
child.deepForEach(function)
}
}
}
usage :
viewGroup.deepForEach { isEnabled = false }
Vertex *f=(findvertex(from));
if(!f) {
cerr << "vertex not found" << endl;
exit(1) // or return;
}
Because findVertex
can return NULL
if it can't find the vertex.
Otherwise this f->adj;
is trying to do
NULL->adj;
Which causes access violation.
There are couple of way which can be used.
const stations = [
{call:'station one',frequency:'000'},
{call:'station two',frequency:'001'}
];
const callList = stations.map(({call}) => call)
Solution 1
<p>{callList.join(', ')}</p>
Solution 2
<ol>
{ callList && callList.map(item => <li>{item}</li>) }
</ol>
Of course there are other ways also available.
You could do it in one line (useful for ci-environments):
taskkill /fi "Services eq SERVICE_NAME" /F
Filter -> Services -> ServiceName equals SERVICE_NAMES -> Force

Everyone has overcomplicated this answer:
some_int = <256 bit integer>
some_bytes = some_int.to_bytes(32, sys.byteorder)
my_bytearray = bytearray(some_bytes)
You just need to know the number of bytes that you are trying to convert. In my use cases, normally I only use this large of numbers for crypto, and at that point I have to worry about modulus and what-not, so I don't think this is a big problem to be required to know the max number of bytes to return.
Since you are doing it as 768-bit math, then instead of 32 as the argument it would be 96.
You can add one
public static boolean isNullOrBlank(String param) {
return param == null || param.trim().length() == 0;
}
I have
public static boolean isSet(String param) {
// doesn't ignore spaces, but does save an object creation.
return param != null && param.length() != 0;
}
based on examples above and examples found on other sites, I created a generic procedure and some examples.

Well System.Reflection.MethodBase.GetCurrentMethod().Name
is not a very good choice 'cause it will just display the method name without additional information.
Like for string MyMethod(string str)
the above property will return just MyMethod
which is hardly adequate.
It is better to use System.Reflection.MethodBase.GetCurrentMethod().ToString()
which will return the entire method signature...

if you are using Swift Mailer: please ensure that your $transport variable is similar to the below, based on tests i have done, that error results from ssl and port misconfiguration. note: you must include 'ssl' or 'tls' in the transport variable.
EXAMPLE CODE:
// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.gmail.com', 465, 'ssl'))
->setUsername([email protected])
->setPassword(password)
;
// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);
// Create a message
$message = (new Swift_Message('News Letter Subscription'))
->setFrom(['[email protected]' => 'A Name'])
->setTo(['[email protected]' => 'A Name'])
->setBody('your message body')
;
// Send the message
$result = $mailer->send($message);
Use the optional font
argument to turtle.write()
, from the docs:
turtle.write(
arg, move=False, align="left", font=("Arial", 8, "normal"))
Parameters:
- arg – object to be written to the TurtleScreen
- move – True/False
- align – one of the strings “left”, “center” or right”
- font – a triple (fontname, fontsize, fonttype)
So you could do something like turtle.write("messi fan", font=("Arial", 16, "normal"))
to change the font size to 16 (default is 8).
We have two commands, first is "condition_command", second is "result_command". If we need run "result_command" when "condition_command" is successful (errorlevel=0):
condition_command && result_command
If we need run "result_command" when "condition_command" is fail:
condition_command || result_command
Therefore for run "some_command" in case when we have "string" in the file "status.txt":
find "string" status.txt 1>nul && some_command
in case when we have not "string" in the file "status.txt":
find "string" status.txt 1>nul || some_command
LEA : just an "arithmetic" instruction..
MOV transfers data between operands but lea is just calculating
I think there's an even easier way now. This enables basic caching for all $http requests (which $resource inherits):
var app = angular.module('myApp',[])
.config(['$httpProvider', function ($httpProvider) {
// enable http caching
$httpProvider.defaults.cache = true;
}])
For a true logical XOR operation, this will work:
if(!A != !B) {
// code here
}
Note the !
are there to convert the values to booleans and negate them, so that two unequal positive integers (each a true
) would evaluate to false
.
For a more generic answer, convert the error value to hex, then lookup the hex value at Windows Task Scheduler Error and Success Constants

Code:
for x in range(1,11):
print(x,end = " ")
This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n
and the output of np.add.reduce()
are both scalars, this implies that the problem lies with xm
and ym
, the two of which are simply your x
and y
inputs minus their respective means.
Based on this, my guess is that your x
and y
inputs have different shapes from one another, making them incompatible for element-wise multiplication.
** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.
Here's an example:
>>> from scipy.stats import norm
>>> norm.cdf(1.96)
0.9750021048517795
>>> norm.cdf(-1.96)
0.024997895148220435
In other words, approximately 95% of the standard normal interval lies within two standard deviations, centered on a standard mean of zero.
If you need the inverse CDF:
>>> norm.ppf(norm.cdf(1.96))
array(1.9599999999999991)
The 2
in Anaconda2
means that the main version of Python will be 2.x rather than the 3.x installed in Anaconda3
. The current release has Python 2.7.13.
The 4.4.0.1
is the version number of Anaconda. The current advertised version is 4.4.0
and I assume the .1
is a minor release or for other similar use. The Windows releases, which I use, just say 4.4.0
in the file name.
Others have now explained the difference between Anaconda and Miniconda, so I'll skip that.
The first part of your question can be solved with just HTML & CSS; you'll need to use Javascript for the second part.
I'm not sure what you mean by "next to": on the same line and near, or on separate lines? If you want all of the radio buttons on the same line, just use margins to push them apart. If you want each of them on their own line, you have two options (unless you want to venture into float:
territory):
<br />s
to split the options apart and some CSS to vertically align them:<style type='text/css'>
.input input
{
width: 20px;
}
</style>
<div class="input radio">
<fieldset>
<legend>What color is the sky?</legend>
<input type="hidden" name="data[Submit][question]" value="" id="SubmitQuestion" />
<input type="radio" name="data[Submit][question]" id="SubmitQuestion1" value="1" />
<label for="SubmitQuestion1">A strange radient green.</label>
<br />
<input type="radio" name="data[Submit][question]" id="SubmitQuestion2" value="2" />
<label for="SubmitQuestion2">A dark gloomy orange</label>
<br />
<input type="radio" name="data[Submit][question]" id="SubmitQuestion3" value="3" />
<label for="SubmitQuestion3">A perfect glittering blue</label>
</fieldset>
</div>
Styling the <label>
is why you'll need to resort to Javascript. A library like jQuery
is perfect for this:
<style type='text/css'>
.input label.focused
{
background-color: #EEEEEE;
font-style: italic;
}
</style>
<script type='text/javascript' src='jquery.js'></script>
<script type='text/javascript'>
$(document).ready(function() {
$('.input :radio').focus(updateSelectedStyle);
$('.input :radio').blur(updateSelectedStyle);
$('.input :radio').change(updateSelectedStyle);
})
function updateSelectedStyle() {
$('.input :radio').removeClass('focused').next().removeClass('focused');
$('.input :radio:checked').addClass('focused').next().addClass('focused');
}
</script>
The focus
and blur
hooks are needed to make this work in IE.
You can add a new column at the end of your table
ALTER TABLE assessment ADD q6 VARCHAR( 255 )
Add column to the begining of table
ALTER TABLE assessment ADD q6 VARCHAR( 255 ) FIRST
Add column next to a specified column
ALTER TABLE assessment ADD q6 VARCHAR( 255 ) after q5
and more options here
BOOL
and BOOLEAN
are synonyms of TINYINT(1)
. Zero is false
, anything else is true
. More information here.
I like Apache commons utils for this type of stuff and use this exact use-case (reading files from classpath) extensively when testing, especially for reading JSON files from /src/test/resources
as part of unit / integration testing. e.g.
public class FileUtils {
public static String getResource(String classpathLocation) {
try {
String message = IOUtils.toString(FileUtils.class.getResourceAsStream(classpathLocation),
Charset.defaultCharset());
return message;
}
catch (IOException e) {
throw new RuntimeException("Could not read file [ " + classpathLocation + " ] from classpath", e);
}
}
}
For testing purposes, it can be nice to catch the IOException
and throw a RuntimeException
- your test class could look like e.g.
@Test
public void shouldDoSomething () {
String json = FileUtils.getResource("/json/input.json");
// Use json as part of test ...
}
This is solved my problem by adding this line:
DirectoryIndex index.php
Since Express.js 3x the response object has a json() method which sets all the headers correctly for you and returns the response in JSON format.
Example:
res.json({"foo": "bar"});
At first, the problem is because you did't put any parameter for mysqli_error. I can see that it has been solved based on the post here. Most probably, the next problem is cause by wrong file path for the included file.. .
Are you sure this code
$myConnection = mysqli_connect("$db_host","$db_username","$db_pass","$db_name") or die ("could not connect to mysql");
is in the 'scripts' folder and your main code file is on the same level as the script folder?
You can use .toggle()
function instead of .click()
....
If you prefer not to use regex, you might try
''.join([i for i in s if i.isalpha()])

Here my take on the subject:
convert.truncate = function(value, decimals) {
decimals = (decimals === undefined ? 0 : decimals);
return parseFloat((value-(0.5/Math.pow(10, decimals))).toFixed(decimals),10);
};
It's just a slightly more elaborate version of
(f - 0.005).toFixed(2)
delete your local branch by following command
git branch -d branch_name
you could also do
git branch -D branch_name
which basically force a delete (even if local not merged to source)
try the below query
DECLARE @Query VARCHAR(max)
SELECT @Query = 'USE ? SELECT ''?'' AS DataBaseName,
sys.columns.name AS ColumnName ,
sys.tables.name AS TableName ,
schema_name (sys.tables.schema_Id) AS schemaName
FROM sys.columns
JOIN sys.tables
ON sys.columns.object_id = sys.tables.object_id
WHERE sys.columns.name = ''id'' '
EXEC SP_MSFOREACHDB @Query
gives list of tables containing ID column from all databases.

... Also, while a const field is a compile-time constant, the readonly field can be used for runtime constants...
So using static in const fields is like trying to make a defined (with #define) static in C/C++... Since it is replaced with its value in compile-time of course it is initiated once for all instances (=static).
There seems to be a lot of bad practice being thrown around Event Handler Attributes. Bad practice is not knowing and using available features where it is most appropriate. The Event Attributes are fully W3C Documented standards and there is nothing bad practice about them. It's no different than placing inline styles, which is also W3C Documented and can be useful in times. Whether you place it wrapped in script tags or not, it's gonna be interpreted the same way.
https://www.w3.org/TR/html5/webappapis.html#event-handler-idl-attributes
For me it was an error in the layout xml binding, I had
app:setNameString="@{person}"
instead of
app:nameString="@{person}"
the type name must match the name you have set up in the @BindingAdapter class (if you are using binding adapter)
If you have installed .NET desktop development and still you can't see the templates, then VS is probably getting the templates from your custom templates folder and not installed.
To fix that, copy the installed templates folder to custom.
This is your "installed" folder
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\ProjectTemplates
This is your "custom" folder
C:\Users[your username]\Documents\Visual Studio\2017\Templates\ProjectTemplates
Typically this happens when you are at the office and you are running VS as an administrator and visual studio is confused how to merge both of them and if you notice they don't have the same folder structure and folder names.. One is CSHARP and the other C#....
I didn't have the same problem when I installed VS 2017 community edition at home though. This happened when I installed visual studio 2017 "enterprise" edition.
You ca also use Response.Write("alert('Error')");
A file object is an instance of Blob but a blob object is not an instance of File
new File([], 'foo.txt').constructor.name === 'File' //true
new File([], 'foo.txt') instanceof File // true
new File([], 'foo.txt') instanceof Blob // true
new Blob([]).constructor.name === 'Blob' //true
new Blob([]) instanceof Blob //true
new Blob([]) instanceof File // false
new File([], 'foo.txt').constructor.name === new Blob([]).constructor.name //false
If you must convert a file object to a blob object, you can create a new Blob object using the array buffer of the file. See the example below.
let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'});
//or let file = document.querySelector('input[type=file]').files[0];
let reader = new FileReader();
reader.onload = function(e) {
let blob = new Blob([new Uint8Array(e.target.result)], {type: file.type });
console.log(blob);
};
reader.readAsArrayBuffer(file);
As pointed by @bgh you can also use the arrayBuffer method of the File object. See the example below.
let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'});
//or let file = document.querySelector('input[type=file]').files[0];
file.arrayBuffer().then((arrayBuffer) => {
let blob = new Blob([new Uint8Array(arrayBuffer)], {type: file.type });
console.log(blob);
});
If your environment supports async/await you can use a one-liner like below
let fileToBlob = async (file) => new Blob([new Uint8Array(await file.arrayBuffer())], {type: file.type });
console.log(await fileToBlob(new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'})));
I use the package enumitem. You may then set such margins when you declare your lists (enumerate, description, itemize):
\begin{itemize}[leftmargin=0cm]
\item Foo
\item Bar
\end{itemize}
Naturally, the package provides lots of other nice customizations for lists (use 'label=' to change the bullet, use 'itemsep=' to change the spacing between items, etc...)
Including "string.h" makes things easier. An easier way to tackle your problem is:
#include <string.h>
char* createStr(){
static char str[20] = "my";
return str;
}
int main(){
char a[20];
strcpy(a,createStr()); //this will copy the returned value of createStr() into a[]
printf("%s",a);
return 0;
}
Git uses "the index" to prepare commits. You can add and remove changes from the index before you commit (in your paste you already have deleted ~10 files with git rm
). When the index looks like you want it, run git commit
.
Usually this will fire up vim
. To insert text hit i
, <esc>
goes back to normal mode, hit ZZ
to save and quit (ZQ
to quit without saving). voilà, there's your commit
In this answer I choose to approach the "Simple Java AES encrypt/decrypt example" main theme and not the specific debugging question because I think this will profit most readers.
This is a simple summary of my blog post about AES encryption in Java so I recommend reading through it before implementing anything. I will however still provide a simple example to use and give some pointers what to watch out for.
In this example I will choose to use authenticated encryption with Galois/Counter Mode or GCM mode. The reason is that in most case you want integrity and authenticity in combination with confidentiality (read more in the blog).
Here are the steps required to encrypt/decrypt with AES-GCM with the Java Cryptography Architecture (JCA). Do not mix with other examples, as subtle differences may make your code utterly insecure.
As it depends on your use-case, I will assume the simplest case: a random secret key.
SecureRandom secureRandom = new SecureRandom();
byte[] key = new byte[16];
secureRandom.nextBytes(key);
SecretKey secretKey = SecretKeySpec(key, "AES");
Important:
SecureRandom
An initialization vector (IV) is used so that the same secret key will create different cipher texts.
byte[] iv = new byte[12]; //NEVER REUSE THIS IV WITH SAME KEY
secureRandom.nextBytes(iv);
Important:
SecureRandom
final Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding");
GCMParameterSpec parameterSpec = new GCMParameterSpec(128, iv); //128 bit auth tag length
cipher.init(Cipher.ENCRYPT_MODE, secretKey, parameterSpec);
byte[] cipherText = cipher.doFinal(plainText);
Important:
CipherInputStream
when encrypting large chunks of datacipher.updateAAD(associatedData);
More here.Just append IV and ciphertext. As stated above, the IV doesn't need to be secret.
ByteBuffer byteBuffer = ByteBuffer.allocate(iv.length + cipherText.length);
byteBuffer.put(iv);
byteBuffer.put(cipherText);
byte[] cipherMessage = byteBuffer.array();
Optionally encode with Base64 if you need a string representation. Either use Android's or Java 8's built-in implementation (do not use Apache Commons Codec - it's an awful implementation). Encoding is used to "convert" byte arrays to string representation to make it ASCII safe e.g.:
String base64CipherMessage = Base64.getEncoder().encodeToString(cipherMessage);
If you have encoded the message, first decode it to byte array:
byte[] cipherMessage = Base64.getDecoder().decode(base64CipherMessage)
Important:
Initialize the cipher and set the same parameters as with the encryption:
final Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding");
//use first 12 bytes for iv
AlgorithmParameterSpec gcmIv = new GCMParameterSpec(128, cipherMessage, 0, 12);
cipher.init(Cipher.DECRYPT_MODE, secretKey, gcmIv);
//use everything from 12 bytes on as ciphertext
byte[] plainText = cipher.doFinal(cipherMessage, 12, cipherMessage.length - 12);
Important:
cipher.updateAAD(associatedData);
if you added it during encryption.A working code snippet can be found in this gist.
Note that most recent Android (SDK 21+) and Java (7+) implementations should have AES-GCM. Older versions may lack it. I still choose this mode, since it is easier to implement in addition to being more efficient compared to similar mode of Encrypt-then-Mac (with e.g. AES-CBC + HMAC). See this article on how to implement AES-CBC with HMAC.
The Groovy way to do this is
def list = []
list << new MyType(...)
which creates a list and uses the overloaded leftShift
operator to append an item
See the Groovy docs on Lists for lots of examples.
Close()
in code?You cannot rely on close reason of the form closing event args, because if the user click X button on title bar or close the form using Alt + F4 or use system menu to close the form or the form get closed by calling Close()
method, all all above cases, the close reason will be Closed by User which is not desired result.
To distinguish if the form closed by X button or by Close
method, you can use either of the following options:
WM_SYSCOMMAND
and check for SC_CLOSE
and set a flag.StackTrace
to see if any of the frames contain Close
method call.Example 1 - Handle WM_SYSCOMMAND
public bool ClosedByXButtonOrAltF4 {get; private set;}
private const int SC_CLOSE = 0xF060;
private const int WM_SYSCOMMAND = 0x0112;
protected override void WndProc(ref Message msg)
{
if (msg.Msg == WM_SYSCOMMAND && msg.WParam.ToInt32() == SC_CLOSE)
ClosedByXButtonOrAltF4 = true;
base.WndProc(ref msg);
}
protected override void OnShown(EventArgs e)
{
ClosedByXButtonOrAltF4 = false;
}
protected override void OnFormClosing(FormClosingEventArgs e)
{
if (ClosedByXButtonOrAltF4)
MessageBox.Show("Closed by X or Alt+F4");
else
MessageBox.Show("Closed by calling Close()");
}
Example 2 - Checking StackTrace
protected override void OnFormClosing(FormClosingEventArgs e)
{
if (new StackTrace().GetFrames().Any(x => x.GetMethod().Name == "Close"))
MessageBox.Show("Closed by calling Close()");
else
MessageBox.Show("Closed by X or Alt+F4");
}
If you need the path
and thedomain
for each cookie, which get_dict()
is not exposes, you can parse the cookies manually, for instance:
[
{'name': c.name, 'value': c.value, 'domain': c.domain, 'path': c.path}
for c in session.cookies
]
First off, this actually is being raised in the next version to 8MB
or 16MB
... but I think to put this into perspective, Eliot from 10gen (who developed MongoDB) puts it best:
EDIT: The size has been officially 'raised' to 16MB
So, on your blog example, 4MB is actually a whole lot.. For example, the full uncompresses text of "War of the Worlds" is only 364k (html): http://www.gutenberg.org/etext/36
If your blog post is that long with that many comments, I for one am not going to read it :)
For trackbacks, if you dedicated 1MB to them, you could easily have more than 10k (probably closer to 20k)
So except for truly bizarre situations, it'll work great. And in the exception case or spam, I really don't think you'd want a 20mb object anyway. I think capping trackbacks as 15k or so makes a lot of sense no matter what for performance. Or at least special casing if it ever happens.
-Eliot
I think you'd be pretty hard pressed to reach the limit ... and over time, if you upgrade ... you'll have to worry less and less.
The main point of the limit is so you don't use up all the RAM on your server (as you need to load all MB
s of the document into RAM when you query it.)
So the limit is some % of normal usable RAM on a common system ... which will keep growing year on year.
Note on Storing Files in MongoDB
If you need to store documents (or files) larger than 16MB
you can use the GridFS API which will automatically break up the data into segments and stream them back to you (thus avoiding the issue with size limits/RAM.)
Instead of storing a file in a single document, GridFS divides the file into parts, or chunks, and stores each chunk as a separate document.
GridFS uses two collections to store files. One collection stores the file chunks, and the other stores file metadata.
You can use this method to store images, files, videos, etc in the database much as you might in a SQL database. I have used this to even store multi gigabyte video files.
Those whitespaces can really be a bother. Try os.chdir('C:/Documents\ and\ Settings/')
followed by relative paths for os.system
, subprocess
methods, or whatever...
If best-effort attempts to bypass the whitespaces-in-path hurdle keep failing, then my next best suggestion is to avoid having blanks in your crucial paths. Couldn't you make a blanks-less directory, copy the crucial .exe
file there, and try that? Are those havoc-wrecking space absolutely essential to your well-being...?
If you are in control of server side, it might be possible to set header value in query string and send it like that? That way you could parse it from query string if it's not found in the headers.
Just an idea... And you asked for a cunning hack :)
There is function in modern JavaScript (ECMAScript 5) called Object.keys
performing this operation:
var obj = { "a" : 1, "b" : 2, "c" : 3};
alert(Object.keys(obj)); // will output ["a", "b", "c"]
Compatibility details can be found here.
On the Mozilla site there is also a snippet for backward compatibility:
if(!Object.keys) Object.keys = function(o){
if (o !== Object(o))
throw new TypeError('Object.keys called on non-object');
var ret=[],p;
for(p in o) if(Object.prototype.hasOwnProperty.call(o,p)) ret.push(p);
return ret;
}
First check out to master:
git checkout master
Do all changes, hotfix and commits and push your master.
Go back to your branch, 'aq', and merge master in it:
git checkout aq
git merge master
Your branch will be up-to-date with master. A good and basic example of merge is 3.2 Git Branching - Basic Branching and Merging.
This program is doing almost everything with Public and private keys. The der format can be obtained but saving raw data ( without encoding base64). I hope this helps programmers.

If I know for sure in my application that the object is not used in search in any of the list or hash data structure and not used equals method elsewhere except the one used indirectly in hash data structure while adding. Is it advisable to update the existing object in set in equals method. Refer the below code. If I add the this bean to HashSet, I can do group aggregation on the matching object on key (id). By this way I am able to achieve aggregation functions such as sum, max, min, ... as well. If not advisable, please feel free to share me your thoughts.
public class MyBean {
String id,
name;
double amountSpent;
@Override
public int hashCode() {
return id.hashCode();
}
@Override
public boolean equals(Object obj) {
if(obj!=null && obj instanceof MyBean ) {
MyBean tmpObj = (MyBean) obj;
if(tmpObj.id!=null && tmpObj.id.equals(this.id)) {
tmpObj.amountSpent += this.amountSpent;
return true;
}
}
return false;
}
}
IndexedTreeSet from the indexed-tree-map project provides this functionality (ordered/sorted set with list-like access by index).
I typically recommend lodash rather than underscore.
If you have it, use it.
If you don't, then you should consider using the lodash.invert npm package, which is pretty tiny.
Here's how you can test it using gulp:
1) Create a file called gulpfile.js with the following contents:
// Filename: gulpfile.js
var gulp = require('gulp');
var invert = require('lodash.invert');
gulp.task('test-invert', function () {
var hash = {
foo: 1,
bar: 2
};
var val = 1;
var key = (invert(hash))[val]; // << Here's where we call invert!
console.log('key for val(' + val + '):', key);
});
2) Install the lodash.invert package and gulp
$ npm i --save lodash.invert && npm install gulp
3) Test that it works:
$ gulp test-invert
[17:17:23] Using gulpfile ~/dev/npm/lodash-invert/gulpfile.js
[17:17:23] Starting 'test-invert'...
key for val(1): foo
[17:17:23] Finished 'test-invert' after 511 µs
References
https://www.npmjs.com/package/lodash.invert
You could use Homebrew.
Then just run:
brew install python3
Assuming you are using Eclipse, on a MAC you can:
Eclipse.app
Eclipse -> Preferences
Java -> Installed JREs
Add...
buttonMacOS X VM
as the JRE type. Press Next./Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home
JDK 1.7
. Click Finish.File -> New -> Java Project
.Use default JRE (currently JDK 1.7)
Hope this helps
try it it is working fine

I have spent some time trying to figure out the difference.
And i think the factory function uses the module pattern and service function uses the standard java script constructor pattern.
I've had good experience with nanotime. It provides wall-clock time as two longs (seconds since the epoch and nanoseconds within that second), using a JNI library. It's available with the JNI part precompiled for both Windows and Linux.
i got the same problem, i used malloc over n over again in a loop for adding new char *string data. i faced the same problem, but after releasing the allocated memory void free()
problem were sorted
if (columnname != a
&& columnname != b

Should do the trick.
A reference is an implicit pointer. Basically you can change the value the reference points to but you can't change the reference to point to something else. So my 2 cents is that if you only want to change the value of a parameter pass it as a reference but if you need to change the parameter to point to a different object pass it using a pointer.
V=`php -v | sed -e '/^PHP/!d' -e 's/.* \([0-9]\+\.[0-9]\+\).*$/\1/'` \
sudo apt-get install php$V-zip
If you want to write the output to a file you can use the stdout-argument of subprocess.call
.
It takes None
, subprocess.PIPE
, a file object or a file descriptor. The first is the default, stdout is inherited from the parent (your script). The second allows you to pipe from one command/process to another. The third and fourth are what you want, to have the output written to a file.
You need to open a file with something like open
and pass the object or file descriptor integer to call
:
f = open("blah.txt", "w")
subprocess.call(["/home/myuser/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], stdout=f)
I'm guessing any valid file-like object would work, like a socket (gasp :)), but I've never tried.
As marcog mentions in the comments you might want to redirect stderr as well, you can redirect this to the same location as stdout with stderr=subprocess.STDOUT
. Any of the above mentioned values works as well, you can redirect to different places.

Installing the Chrome extension IE Tab did the job for me.
It has the ability to auto-detect URLs so whenever I browse to our SharePoint it emulates Internet Explorer. Finally I can open Office documents directly from Chrome.
You can install IETab for FireFox too.
You can delete it in the terminal via:
jupyter kernelspec uninstall yourKernel
where yourKernel
is the name of the kernel you want to delete.
This is simple way to Display Div using:-
$("#musicinfo").show(); //or
$("#musicinfo").css({'display':'block'}); //or
$("#musicinfo").toggle("slow"); //or
$("#musicinfo").fadeToggle(); //or
var idPost=document.getElementById("status").innerHTML;
The 'status' element does not exist in your webpage.
So document.getElementById("status") return null. While you can not use innerHTML property of NULL.
You should add a condition like this:
if(document.getElementById("status") != null){
var idPost=document.getElementById("status").innerHTML;
}
Hope this answer can help you. :)
various option are available such as:
Double d= 123.12;
BigDecimal b = new BigDecimal(d, MathContext.DECIMAL64); // b = 123.1200000
b = b.setScale(2, BigDecimal.ROUND_HALF_UP); // b = 123.12
BigDecimal b1 =new BigDecimal(collectionFileData.getAmount(), MathContext.DECIMAL64).setScale(2, BigDecimal.ROUND_HALF_UP) // b1= 123.12
d = (double) Math.round(d * 100) / 100;
BigDecimal b2 = new BigDecimal(d.toString()); // b2= 123.12
Now in iOS 6 and above, you can use:
[[Picker presentingViewController] dismissViewControllerAnimated:YES completion:nil];
Instead of:
[[Picker parentViewControl] dismissModalViewControllerAnimated:YES];
...And you can use:
[self presentViewController:picker animated:YES completion:nil];
Instead of
[self presentModalViewController:picker animated:YES];
Without looking at it, set it to not itself. I don't know how to code it in Java, but in Objective-C I would say
booleanVariable = !booleanVariable;
This flips the variable.
I have used this simple code, and it works!
for (int i = 0; i < N * N; i++)
{
Thread.Sleep(50);
progressBar1.BeginInvoke(new Action(() => progressBar1.Value = i));
progressBar1.CreateGraphics().DrawString(i.ToString() + "%", new Font("Arial",
(float)10.25, FontStyle.Bold),
Brushes.Red, new PointF(progressBar1.Width / 2 - 10, progressBar1.Height / 2 - 7));
}
It just has one simple problem and this is it: when progress bar start to rising, percentage some times hide, and then appear again. I did't write it myself.I found it here: text on progressbar in c#
I used this code, and it does work.
on linux with g++ check out this lib
https://sourceforge.net/projects/libcsdbg
it does all the work for you
For me DownloadSVN is the best SVN client no install no explore shell integration so no need to worry about system instability small and very light weight and it does a great job just recently i had a very bad experience with TortoiseSVN on my WindowsXP_x86:) luckily i found this great SVN client
In order to change the label size you can select an appropriate size policy for the label like expanding or minimum expanding.
You can scale the pixmap by keeping its aspect ratio every time it changes:
QPixmap p; // load pixmap
// get label dimensions
int w = label->width();
int h = label->height();
// set a scaled pixmap to a w x h window keeping its aspect ratio
label->setPixmap(p.scaled(w,h,Qt::KeepAspectRatio));
There are two places where you should add this code:
resizeEvent
of the widget that contains the labelI tried re-creating this, and .someclass.notip
was being generated for me but .someclass:not(.notip)
was not, for as long as I did not have the @mixin tip()
defined. Once I had that, it all worked.
http://sassmeister.com/gist/9775949
$dropdown-width: 100px;
$comp-tip: true;
@mixin tip($pos:right) {
}
@mixin dropdown-pos($pos:right) {
&:not(.notip) {
@if $comp-tip == true{
@if $pos == right {
top:$dropdown-width * -0.6;
background-color: #f00;
@include tip($pos:$pos);
}
}
}
&.notip {
@if $pos == right {
top: 0;
left:$dropdown-width * 0.8;
background-color: #00f;
}
}
}
.someclass { @include dropdown-pos(); }
EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'.
it what I get when I remove @mixin tip($pos:right) { }
I have a child aspx form that does an address lookup server side. The values from the child aspx page are then passed back to the parent textboxes via javascript client side.
Although you can see the textboxes have been changed neither ReadOnly or Enabled would allow the values to be posted back in the parent form.
Here is the example directly from PEP 8 on limiting line length:
class Rectangle(Blob):
def __init__(self, width, height,
color='black', emphasis=None, highlight=0):
if (width == 0 and height == 0 and
color == 'red' and emphasis == 'strong' or
highlight > 100):
raise ValueError("sorry, you lose")
if width == 0 and height == 0 and (color == 'red' or
emphasis is None):
raise ValueError("I don't think so -- values are %s, %s" %
(width, height))
Blob.__init__(self, width, height,
color, emphasis, highlight)
In Asp.net Core 3+ Vesrion
Controller: If wants to return anything related to IActionResult & Data also, go for Controllercontroller
ApiController: Used as attribute/notation in API controller. That inherits ControllerBase Class
ControllerBase: If wants to return data only go for ControllerBase class
You can try that one:
$string = preg_replace('/[^0-9]/', '', $string);
Cheers.
Similar to the others:
cols <- c("premium","change","newprice")
colnames(dataframe) <- cols
Quite simple and easy to modify.
You are iterating trough items in words but you have to iterate through item's length:
words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']
c = 0
for i in range(len(words)):
w1 = words[i]
if w1[0] == w1[len(w1) - 1]:
c += 1
print (c)
In your case i[0] is 'aba' because i is calculated from items in words:
words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']
c = 0
for i in words:
print(i)
the output is:
aba
use "%zo" for off_t. (octal) or "%zu" for decimal.
Parse
throws an exception if it cannot parse the value, whereas TryParse
returns a bool
indicating whether it succeeded.
TryParse
does not just try
/catch
internally - the whole point of it is that it is implemented without exceptions so that it is fast. In fact the way it is most likely implemented is that internally the Parse
method will call TryParse
and then throw an exception if it returns false
.
In a nutshell, use Parse
if you are sure the value will be valid; otherwise use TryParse
.
ffmpeg is writing that information to stderr
, not stdout
. Try this:
ffmpeg -i file.mp4 2>&1 | grep Duration | sed 's/Duration: \(.*\), start/\1/g'
Notice the redirection of stderr
to stdout
: 2>&1
EDIT:
Your sed
statement isn't working either. Try this:

I got a shortcut for Idle (Python GUI).
To start the standalone Device Monitor application, enter the following on the command line in the android-sdk/tools/ directory:
monitor
But remember Most of the Android Device Monitor componenets are deprecated after 3.0 For detail info visit this link
I use this to get the Parent, similarly for child
$( this ).children( 'li.target' ).css("border", "3px double red");
Good Luck
Actually, this is NOT totally correct. I arrived at this page, trying to answer this question myself, as we are transitioning production GitLab server from http://
to https://
and most stuff is working as described above, but when you login to https://server
and everything looks fine ... except when you browse to a project or repository, and it displays the SSH and HTTP instructions... It says "http" and the instructions it displays also say "http".
I found some more things to edit though:
/home/git/gitlab/config/gitlab.yml
production: &base
gitlab:
host: git.domain.com
# Also edit these:
port: 443
https: true
...
and
/etc/nginx/sites-available/gitlab
server {
server_name git.domain.com;
# Also edit these:
listen 443 ssl;
ssl_certificate /etc/ssl/certs/somecert.crt;
ssl_certificate_key /etc/ssl/private/somekey.key;

Try setting a Windows System Environment variable called _JAVA_OPTIONS
with the heap size you want. Java should be able to find it and act accordingly.
Both will works like a charm :),
JAVASCRIPT:
function CopyToClipboard(containerid) {
if (document.selection) {
var range = document.body.createTextRange();
range.moveToElementText(document.getElementById(containerid));
range.select().createTextRange();
document.execCommand("copy");
} else if (window.getSelection) {
var range = document.createRange();
range.selectNode(document.getElementById(containerid));
window.getSelection().addRange(range);
document.execCommand("copy");
alert("text copied")
}}
Also in html,
<button id="button1" onclick="CopyToClipboard('div1')">Click to copy</button>
<div id="div1" >Text To Copy </div>
<textarea placeholder="Press ctrl+v to Paste the copied text" rows="5" cols="20"></textarea>
In my thinking a user stops writing when he doesn't keep focus on that input. For this you have a function called "blur" which does stuff like
Both getsize()
and stat()
will throw an exception if the file does not exist. This function will return True/False without throwing (simpler but less robust):
import os
def is_non_zero_file(fpath):
return os.path.isfile(fpath) and os.path.getsize(fpath) > 0
Hold down the Alt key and drag the pictures to snap to the upper left corner of the cell.
Format the picture and in the Properties tab select "Move but don't size with cells"
Now you can sort the data table by any column and the pictures will stay with the respective data.

You can bind the 'input' event to the textbox. This would fire every time the input changes, so when you paste something (even with right click), delete and type anything.
$('#myTextbox').on('input', function() {
// do something
});
If you use the change
handler, this will only fire after the user deselects the input box, which may not be what you want.
There is an example of both here: http://jsfiddle.net/6bSX6/
You can also make it a reusable method by expending JavaScript:
Array.prototype.findIndexBy = function(key, value) {
return this.findIndex(item => item[key] === value)
}
const peoples = [{name: 'john'}]
const cats = [{id: 1, name: 'kitty'}]
peoples.findIndexBy('name', 'john')
cats.findIndexBy('id', 1)
If you want to unit test code then you need to isolate your code you want to test (in this case your service) from external resources (e.g. databases). You could probably do this with some sort of in-memory EF provider, however a much more common way is to abstract away your EF implementation e.g. with some sort of repository pattern. Without this isolation any tests you write will be integration tests, not unit tests.
As for testing EF code - I write automated integration tests for my repositories that write various rows to the database during their initialization, and then call my repository implementations to make sure that they behave as expected (e.g. making sure that results are filtered correctly, or that they are sorted in the correct order).
These are integration tests not unit tests, as the tests rely on having a database connection present, and that the target database already has the latest up-to-date schema installed.
(For anyone still interested in the topic.)
Consider this (includes even usage of statements' return values in further statements within the "multiline" lambda, although it's ugly to the point of vomiting ;-)
>>> def foo(arg):
... result = arg * 2;
... print "foo(" + str(arg) + ") called: " + str(result);
... return result;
...
>>> f = lambda a, b, state=[]: [
... state.append(foo(a)),
... state.append(foo(b)),
... state.append(foo(state[0] + state[1])),
... state[-1]
... ][-1];
>>> f(1, 2);
foo(1) called: 2
foo(2) called: 4
foo(6) called: 12
12
Actually the orderBy
filter can take as a parameter not only a string but also a function. From the orderBy
documentation: https://docs.angularjs.org/api/ng/filter/orderBy):
function: Getter function. The result of this function will be sorted using the <, =, > operator.
So, you could write your own function. For example, if you would like to compare cards based on a sum of opt1 and opt2 (I'm making this up, the point is that you can have any arbitrary function) you would write in your controller:
$scope.myValueFunction = function(card) {
return card.values.opt1 + card.values.opt2;
};
and then, in your template:
ng-repeat="card in cards | orderBy:myValueFunction"
The other thing worth noting is that orderBy
is just one example of AngularJS filters so if you need a very specific ordering behaviour you could write your own filter (although orderBy
should be enough for most uses cases).
There is an alternative approach I used when I couldn't rely on the EXCEPTION
block at the bottom of my procedure. I had variables declared at the beginning:
my_value VARCHAR := 'default';
number_rows NUMBER := 0;
.
.
.
SELECT count(*) FROM TABLE INTO number_rows (etc.)
IF number_rows > 0 -- Then obtain my_value with a query or constant, etc.
END IF;
