I made another variant with dropdown menu (perhaps for advanced search etc).. Here is how it looks like:
<div class="input-group my-4 col-6 mx-auto">
<input class="form-control py-2 border-right-0 border" type="search" placeholder="Type something..." id="example-search-input">
<span class="input-group-append">
<button type="button" class="btn btn-outline-primary dropdown-toggle dropdown-toggle-split border border-left-0 border-right-0 rounded-0" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>
</button>
<button class="btn btn-outline-primary rounded-right" type="button">
<i class="fas fa-search"></i>
</button>
<div class="dropdown-menu dropdown-menu-right">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
<div role="separator" class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Separated link</a>
</div>
</span>
</div>
Note: It appears green in the screenshot because my site main theme is green.
I hope this is one of the basic conditional classes
Solution: 1
<section [ngClass]="(condition)? 'class1 class2 ... classN' : 'another class1 ... classN' ">
Solution 2
<section [ngClass]="(condition)? 'class1 class2 ... classN' : '(condition)? 'class1 class2 ... classN':'another class' ">
Solution 3
<section [ngClass]="'myclass': condition, 'className2': condition2">

pip install -r requirements.txt

pip3 install -r requirements.txt

Even without looking at assembly, the most obvious reason is that /= 2
is probably optimized as >>=1
and many processors have a very quick shift operation. But even if a processor doesn't have a shift operation, the integer division is faster than floating point division.
Edit: your milage may vary on the "integer division is faster than floating point division" statement above. The comments below reveal that the modern processors have prioritized optimizing fp division over integer division. So if someone were looking for the most likely reason for the speedup which this thread's question asks about, then compiler optimizing /=2
as >>=1
would be the best 1st place to look.
On an unrelated note, if n
is odd, the expression n*3+1
will always be even. So there is no need to check. You can change that branch to
{
n = (n*3+1) >> 1;
count += 2;
}
So the whole statement would then be
if (n & 1)
{
n = (n*3 + 1) >> 1;
count += 2;
}
else
{
n >>= 1;
++count;
}
I had the same issue. This is my solution using angular documentation and firebase Token:
getService() {
const accessToken=this.afAuth.auth.currentUser.getToken().then(res=>{
const httpOptions = {
headers: new HttpHeaders({
'Content-Type': 'application/json',
'Authorization': res
})
};
return this.http.get('Url',httpOptions)
.subscribe(res => console.log(res));
}); }}
I have created actions to clear state. So when I dispatch a logout action creator I dispatch actions to clear state as well.
User record action
export const clearUserRecord = () => ({
type: CLEAR_USER_RECORD
});
Logout action creator
export const logoutUser = () => {
return dispatch => {
dispatch(requestLogout())
dispatch(receiveLogout())
localStorage.removeItem('auth_token')
dispatch({ type: 'CLEAR_USER_RECORD' })
}
};
Reducer
const userRecords = (state = {isFetching: false,
userRecord: [], message: ''}, action) => {
switch (action.type) {
case REQUEST_USER_RECORD:
return { ...state,
isFetching: true}
case RECEIVE_USER_RECORD:
return { ...state,
isFetching: false,
userRecord: action.user_record}
case USER_RECORD_ERROR:
return { ...state,
isFetching: false,
message: action.message}
case CLEAR_USER_RECORD:
return {...state,
isFetching: false,
message: '',
userRecord: []}
default:
return state
}
};
I am not sure if this is optimal?
I want columns One and Two to shrink/grow to fit rather than being fixed.
Have you tried: flex-basis: auto
or this:
flex: 1 1 auto
, which is short for:
flex-grow: 1
(grow proportionally)flex-shrink: 1
(shrink proportionally)flex-basis: auto
(initial size based on content size)or this:
main > section:first-child {
flex: 1 1 auto;
overflow-y: auto;
}
main > section:nth-child(2) {
flex: 1 1 auto;
overflow-y: auto;
}
main > section:last-child {

I know this doesn't use flexbox, but for the simple use-case of three items (one at left, one at center, one at right), this can be accomplished easily using display: grid

I think you need the btn class.
It would be like this:
<a class="btn disabled" href="#">Disabled link</a>
Here's a possible solution.
HTML
<img id="source" src="http://www.byui.edu/images/agriculture-life-sciences/flower.jpg" />
<div id="crop">
<img id="overlay" src="http://www.byui.edu/images/agriculture-life-sciences/flower.jpg" />
</div>
CSS
#crop {
overflow: hidden;
position: absolute;
left: 100px;
top: 100px;
width: 450px;
height: 150px;
}
#overlay {
-webkit-filter:blur(4px);
filter:blur(4px);
width: 450px;
}
#source {
height: 300px;
width: auto;
position: absolute;
left: 100px;
top: 100px;
}
I know the CSS can be simplified and you probably should get rid of the ids. The idea here is to use a div as a cropping container and then apply blur on duplicate of the image. Fiddle
To make this work in Firefox, you would have to use SVG hack.
For anyone who landed here with this error, like I did:
Unable to obtain LocalDateTime from TemporalAccessor: {HourOfAmPm=0, MinuteOfHour=0}
It came from a the following line:
LocalDateTime.parse(date, DateTimeFormatter.ofPattern("M/d/yy h:mm"));
It turned out that it was because I was using a 12hr Hour pattern on a 0 hour, instead of a 24hr pattern.
Changing the hour to 24hr pattern by using a capital H fixes it:
LocalDateTime.parse(date, DateTimeFormatter.ofPattern("M/d/yy H:mm"));
I also faced the error code when i upgraded my java version to 1.8. The problem was with my eclipse.
My jdk which was installed on my system is of 32 - bit and my eclipse was of 64 - bit.
So solve this problem i downloaded the 32 - bit eclipse.
IMO this Architecture miss match problem
Plese match your architecture type of JDK and eclipse.
Updating the PATH Environment Variable
If you do not set the PATH variable, you need to specify the full path to the executable file every time you run it, such as:
C:\> "C:\Program Files\Java\jdk1.8.0\bin\javac" MyClass.java
It is useful to set the PATH variable permanently so it will persist after rebooting.
To set the PATH variable permanently, add the full path of the jdk1.8.0\bin directory to the PATH variable. Typically, this full path looks something like
C:\Program Files\Java\jdk1.8.0\bin
.
Set the PATH variable as follows on Microsoft Windows:
Add the location of the bin folder of the JDK installation to the PATH variable in System Variables.
The following is a typical value for the PATH variable:
C:\WINDOWS\system32;C:\WINDOWS;C:\Program Files\Java\jdk1.8.0\bin
Note:
The PATH environment variable is a series of directories separated by semicolons (;) and is not case-sensitive. Microsoft Windows looks for programs in the PATH directories in order, from left to right.
You should only have one bin directory for a JDK in the path at a time. Those following the first instance are ignored.
If you are not sure where to add the JDK path, append it.
The new path takes effect in each new command window you open after setting the PATH variable.
Currently it only works for the .dropdown-menu
:
.dropdown-menu .divider {
height: 1px;
margin: 9px 0;
overflow: hidden;
background-color: #e5e5e5;
}
If you want it for other use, in your own css, following the bootstrap.css create another one:
.divider {
height: 1px;
width:100%;
display:block; /* for use on default inline elements like span */
margin: 9px 0;
overflow: hidden;
background-color: #e5e5e5;
}
You should declare in the Project structure(Ctrl+Alt+Shift+s) in the Module section mark your folders which of them are source package(blue one) and which are test ...
You could also use indexOf instead to do this
var i = review.indexOf('\u2022 \u2022 \u2022');
if (i !== -1) review.splice(i,1);
I was executing a get request an also want to see just the response and nothing else, seems like magic is done with -silent,-s option.
From the curl man page:
-s, --silent Silent or quiet mode. Don't show progress meter or error messages. Makes Curl mute. It will still output the data you ask for, potentially even to the terminal/stdout unless you redirect it.
Below the examples:
curl -s "http://host:8080/some/resource"
curl -silent "http://host:8080/some/resource"
Using custom headers
curl -s -H "Accept: application/json" "http://host:8080/some/resource")
Using POST method with a header
curl -s -X POST -H "Content-Type: application/json" "http://host:8080/some/resource") -d '{ "myBean": {"property": "value"}}'
You can also customize the output for specific values with -w, below the options I use to get just response codes of the curl:
curl -s -o /dev/null -w "%{http_code}" "http://host:8080/some/resource"
urllib.request.urlopen(url).read()
should return you the raw HTML page as a string.
Works great, minimal setup and no third parties.
According to Chrome's documentation:
Here's the updated workflow:What happens when you blackbox a script?
Exceptions thrown from library code will not pause (if Pause on exceptions is enabled), Stepping into/out/over bypasses the library code, Event listener breakpoints don't break in library code, The debugger will not pause on any breakpoints set in library code. The end result is you are debugging your application code instead of third party resources.

It's an excellent tool to have:
Visual Event is an open-source Javascript bookmarklet which provides debugging information about events that have been attached to DOM elements. Visual Event shows:
- Which elements have events attached to them
- The type of events attached to an element
- The code that will be run with the event is triggered
- The source file and line number for where the attached function was defined (Webkit browsers and Opera only)
You can pause the code when you click somewhere in the page, or when the DOM is modified... and other kinds of JS breakpoints that will be useful to know. You should apply blackboxing here to avoid a nightmare.
In this instance, I want to know what exactly goes on when I click the button.
Open Dev Tools -> Sources tab, and on the right find Event

With Dev Tools activated, you can search the whole codebase (all code in all files) with ?+?+F or:

Be aware sometimes there's not only an img
but lots of elements stacked, and you may not know which one triggers the code.
If this is a bit out of your knowledge, take a look at Chrome's tutorial on debugging.
This is possible if the browser supports the download

I don't have Python 2.7 installed, but in Python 3.3 calling Popen

set to sys.stdout
worked just fine. Not before I had escaped the backslashes in the path, though.

In my case I only wanted the image to behave responsively at mobile scale so I created a css style .myimgrsfix that only kicks in at mobile scale
.myimgrsfix {

}
}
and applied that to the image <img class='img-responsive myimgrsfix' src='whatever.gif'>
Here's a fixed version of it: http://play.golang.org/p/w2ZcOzGHKR
The biggest fix that was needed is when Unmarshalling an array, that property needs to be an array/slice in the struct as well.
For example:
{ "things": ["a", "b", "c"] }
Would Unmarshal into a:
type Item struct {
Things []string
}
And not into:
type Item struct {
Things string
}
The other thing to watch out for when Unmarshaling is that the types line up exactly. It will fail when Unmarshalling a JSON string representation of a number into an int
or float
field -- "1"
needs to Unmarshal into a string
, not into an int
like we saw with ShippingAdditionalCost int

It would be helpful if you provided more information - e.g. what OS your using, what you want to accomplish, etc. But, generally speaking cURL is a very powerful command-line tool I frequently use (in linux) for imitating HTML requests:
For example:
curl --data "post1=value1&post2=value2&etc=valetc" http://host/resource
OR, for a RESTful API:
curl -X POST -d @file http://host/resource
You can check out more information here-> http://curl.haxx.se/
EDITs:
OK. So basically you're looking to stress test your REST server? Then cURL really isn't helpful unless you want to write your own load-testing program, even then sockets would be the way to go. I would suggest you check out Gatling. The Gatling documentation explains how to set up the tool, and from there your can run all kinds of GET, POST, PUT and DELETE requests.
Unfortunately, short of writing your own program - i.e. spawning a whole bunch of threads and inundating your REST server with different types of requests - you really have to rely on a stress/load-testing toolkit. Just using a REST client to send requests isn't going to put much stress on your server.
More EDITs
So in order to simulate a post request on a socket, you basically have to build the initial socket connection with the server. I am not a C# guy, so I can't tell you exactly how to do that; I'm sure there are 1001 C# socket tutorials on the web. With most RESTful APIs you usually need to provide a URI to tell the server what to do. For example, let's say your API manages a library, and you are using a POST request to tell the server to update information about a book with an id of '34'. Your URI might be
http://localhost/library/book/34
Therefore, you should open a connection to localhost on port 80 (or 8080, or whatever port your server is on), and pass along an HTML request header. Going with the library example above, your request header might look as follows:
POST library/book/34 HTTP/1.0\r\n
X-Requested-With: XMLHttpRequest\r\n
Content-Type: text/html\r\n
Referer: localhost\r\n
Content-length: 36\r\n\r\n
title=Learning+REST&author=Some+Name
From here, the server should shoot back a response header, followed by whatever the API is programed to tell the client - usually something to say the POST succeeded or failed. To stress test your API, you should essentially do this over and over again by creating a threaded process.
Also, if you are posting JSON data, you will have to alter your header and content accordingly. Frankly, if you are looking to do this quick and clean, I would suggest using python (or perl) which has several libraries for creating POST, PUT, GET and DELETE request, as well as POSTing and PUTing JSON data. Otherwise, you might end up doing more programming than stress testing. Hope this helps!
According to the grammar in the CSP spec, you need to specify schemes as scheme:
, not just scheme
. So, you need to change the image source directive to:
img-src 'self' data:;
Paul Dardeau answer is perfect, the only thing is, what if all the files inside those folders are not PDF files and you want to grab it all no matter the extension. Well just change it to
find . -name "*.*" -type f -exec cp {} ./pdfsfolder \;
Just to sum up!
There is no z-index for svgs. But svg determines which of your elements are the uppermost by theire position in the DOM. Thus you can remove the Object and place it to the end of the svg making it the "last rendered" element. That one is then rendered "topmost" visually.
Using jQuery:
function moveUp(thisObject){
thisObject.appendTo(thisObject.parents('svg>g'));

exit code 139 (people say this means memory fragmentation)
No, it means that your program died with signal 11
(SIGSEGV
on Linux and most other UNIXes), also known as segmentation fault
.
Could anybody tell me why the run fails but debug doesn't?
Your program exhibits undefined behavior, and can do anything (that includes appearing to work correctly sometimes).
Your first step should be running this program under Valgrind, and fixing all errors it reports.
If after doing the above, the program still crashes, then you should let it dump core (ulimit -c unlimited; ./a.out
) and then analyze that core dump with GDB: gdb ./a.out core
; then use where
command.
A little bit late but I got the same error and I realized that it was because I copied some code from a PDF. Check the difference between these two:
-
-
The first one is from hitting the minus sign on keyboard and the second is from a latex generated PDF.
For debugging purposes, you could use print(repr(data))
.
To display text, always print Unicode. Don't hardcode the character encoding of your environment such as Cp850 inside your script. To decode the HTTP response, see A good way to get the charset/encoding of an HTTP response in Python.
To print Unicode to Windows console, you could use win-unicode-console
package.
transition-property:width;
This should work. you have to have browser dependent code
Install rubygems-update
gem install rubygems-update
update_rubygems
gem update --system
run this commands as root or use sudo.

Rich Sutton's answer finally worked for me, after I realized that adding access_type=offline
is done on the front end client's request for an authorization code, not the back end request that exchanges that code for an access_token. I've added a comment to his answer and this link at Google for more info about refreshing tokens.
P.S. If you are using Satellizer, here is how to add that option to the $authProvider.google in AngularJS.
Try this:
// convert from bitmap to byte array
public byte[] getBytesFromBitmap(Bitmap bitmap) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 70, stream);
return stream.toByteArray();
}
// get the base 64 string
String imgString = Base64.encodeToString(getBytesFromBitmap(someImg),
Base64.NO_WRAP);
Fragments lives within the Activity and has:
Think of Fragments as a sub activity of the main activity it belongs to, it cannot exist of its own and it can be called/reused again and again. Hope this helps :)
Decode it with the unicode-escape
codec:
>>> a="Hello\u2026"
>>> a.decode('unicode-escape')
u'Hello\u2026'
>>> print _
Hello…
This is because for a non-unicode string the \u2026
is not recognised but is instead treated as a literal series of characters (to put it more clearly, 'Hello\\u2026'
). You need to decode the escapes, and the unicode-escape
codec can do that for you.
Note that you can get unicode
to recognise it in the same way by specifying the codec argument:
>>> unicode(a, 'unicode-escape')
u'Hello\u2026'
But the a.decode()
way is nicer.
If you want a popup window rather than a <div />
, I would suggest the following approach.
In your parent page, you call a small helper method to show the popup window:
<input type="button" name="choice" onClick="selectValue('sku1')" value="?">
Add the following JS methods:
function selectValue(id)
{
// open popup window and pass field id
window.open('sku.php?id=' + encodeURIComponent(id),'popuppage',
'width=400,toolbar=1,resizable=1,scrollbars=yes,height=400,top=100,left=100');
}
function updateValue(id, value)
{
// this gets called from the popup window and updates the field with a new value
document.getElementById(id).value = value;
}
Your sku.php
receives the selected field via $_GET['id']
and uses it to construct the parent callback function:
?>
<script type="text/javascript">
function sendValue(value)
{
var parentId = <?php echo json_encode($_GET['id']); ?>;
window.opener.updateValue(parentId, value);
window.close();
}
</script>
For each row in your popup, change code to this:
<td><input type=button value="Select" onClick="sendValue('<?php echo $rows['packcode']; ?>')" /></td>
Following this approach, the popup window doesn't need to know how to update fields in the parent form.
I use this...but have never done any metro app development, so I don't know of any restrictions on libraries available to you. (note, you'll need to mark your classes as with DataContract and DataMember attributes)
public static class JSONSerializer<TType> where TType : class
{
/// <summary>
/// Serializes an object to JSON
/// </summary>
public static string Serialize(TType instance)
{
var serializer = new DataContractJsonSerializer(typeof(TType));
using (var stream = new MemoryStream())
{
serializer.WriteObject(stream, instance);
return Encoding.Default.GetString(stream.ToArray());
}
}
/// <summary>
/// DeSerializes an object from JSON
/// </summary>
public static TType DeSerialize(string json)
{
using (var stream = new MemoryStream(Encoding.Default.GetBytes(json)))
{
var serializer = new DataContractJsonSerializer(typeof(TType));
return serializer.ReadObject(stream) as TType;
}
}
}
So, if you had a class like this...
[DataContract]
public class MusicInfo
{
[DataMember]
public string Name { get; set; }
[DataMember]
public string Artist { get; set; }
[DataMember]
public string Genre { get; set; }
[DataMember]
public string Album { get; set; }
[DataMember]
public string AlbumImage { get; set; }
[DataMember]
public string Link { get; set; }
}
Then you would use it like this...
var musicInfo = new MusicInfo
{
Name = "Prince Charming",
Artist = "Metallica",
Genre = "Rock and Metal",
Album = "Reload",
AlbumImage = "http://up203.siz.co.il/up2/u2zzzw4mjayz.png",
Link = "http://f2h.co.il/7779182246886"
};
// This will produce a JSON String
var serialized = JSONSerializer<MusicInfo>.Serialize(musicInfo);
// This will produce a copy of the instance you created earlier
var deserialized = JSONSerializer<MusicInfo>.DeSerialize(serialized);
I set 127.0.0.1 localhost, and solve this problem.

Here is the latest answer using a well optimized and nice csv plugin: (The code may not work on stackoverflow here but will work in your project as i have tested it myself)
Using jquery and jquery.csv library (Very well optimized and perfectly escapes everything) https://github.com/typeiii/jquery-csv

If you read the jquery docs, there are numerous reasons for something to not be considered visible/hidden:
They have a CSS display value of none.
They are form elements with type="hidden".
Their width and height are explicitly set to 0.
An ancestor element is hidden, so the element is not shown on the page.
http://api.jquery.com/visible-selector/
Here's a small jsfiddle example with one visible and one hidden element:
As others have responded, the key you are trying to parse doesn't have the proper PKCS#8 headers which Oracle's PKCS8EncodedKeySpec
needs to understand it. If you don't want to convert the key using openssl pkcs8
or parse it using JDK internal APIs you can prepend the PKCS#8 header like this:
static final Base64.Decoder DECODER = Base64.getMimeDecoder();
private static byte[] buildPKCS8Key(File privateKey) throws IOException {
final String s = new String(Files.readAllBytes(privateKey.toPath()));
if (s.contains("--BEGIN PRIVATE KEY--")) {
return DECODER.decode(s.replaceAll("-----\\w+ PRIVATE KEY-----", ""));
}
if (!s.contains("--BEGIN RSA PRIVATE KEY--")) {
throw new RuntimeException("Invalid cert format: "+ s);
}
final byte[] innerKey = DECODER.decode(s.replaceAll("-----\\w+ RSA PRIVATE KEY-----", ""));
final byte[] result = new byte[innerKey.length + 26];
System.arraycopy(DECODER.decode("MIIEvAIBADANBgkqhkiG9w0BAQEFAASCBKY="), 0, result, 0, 26);
System.arraycopy(BigInteger.valueOf(result.length - 4).toByteArray(), 0, result, 2, 2);
System.arraycopy(BigInteger.valueOf(innerKey.length).toByteArray(), 0, result, 24, 2);
System.arraycopy(innerKey, 0, result, 26, innerKey.length);
return result;
}
Once that method is in place you can feed it's output to the PKCS8EncodedKeySpec
constructor like this: new PKCS8EncodedKeySpec(buildPKCS8Key(privateKey));
I believe you could do it like this :
var fd = new FormData();
fd.append( 'file', input.files[0] );
$.ajax({
url: 'http://example.com/script.php',
data: fd,
processData: false,
contentType: false,
type: 'POST',
success: function(data){
alert(data);
}
});
Notes:
Setting processData
to false
lets you prevent jQuery from automatically transforming the data into a query string. See the docs for more info.
Setting the contentType
to false
is imperative, since otherwise jQuery will set it incorrectly.
A simple way is to write it:
Dim rs As Object
Set rs = Me.Recordset.Clone
If Me.Recordset.RecordCount = 0 then 'checks for number of records
msgbox "There is no records"
End if
String.format()
to the rescue!!
This will be validated by compiler, so you won't mix up indices accidentally.
NSDictionary *stateStrings =
@{
@(MCSessionStateNotConnected) : @"MCSessionStateNotConnected",
@(MCSessionStateConnecting) : @"MCSessionStateConnecting",
@(MCSessionStateConnected) : @"MCSessionStateConnected",
};
NSString *stateString = [stateStrings objectForKey:@(state)];
var stateStrings: [MCSessionState: String] = [
.notConnected : "MCSessionState.notConnected",
.connecting : "MCSessionState.connecting",
.connected : "MCSessionState.connected"
]
var stateString = stateStrings[MCSessionState.Connected]
UPDATE: A more Swifty way is to extend the enum with CustomStringConvertible
conformance. Also, this way the compiler will safeguard to implement every new addition to the underlying enum (whereas using arrays does not), as switch
statements must be exhaustive.
extension MCSessionState: CustomStringConvertible {
public var description: String {
switch self {
case .notConnected:
return "MCSessionState.notConnected"
case .connecting:
return "MCSessionState.connecting"
case .connected:
return "MCSessionState.connected"
@unknown default:
return "Unknown"
}
}
}
// You can use it like this.
var stateString = MCSessionState.connected.description
// Or this.
var stateString = "\(MCSessionState.connected)"
Unfortunatelly, to remove one backlash as mentioned in first comment (newbiedoodle) don't lead to good result. Most (if not all) IDE issues syntax error. The reason is in this, that Java Escaped Unicode format expects syntax "\uXXXX", where XXXX are 4 hexadecimal digits, which are mandatory. Attempts to fold this string from pieces fails. Of course, "\u" is not the same as "\\u". The first syntax means escaped 'u', second means escaped backlash (which is backlash) followed by 'u'. It is strange, that on the Apache pages is presented utility, which doing exactly this behavior. But in reality, it is Escape mimic utility. Apache has some its own utilities (i didn't testet them), which do this work for you. May be, it is still not that, what you want to have. Apache Escape Unicode utilities But this utility 1 have good approach to the solution. With combination described above (MeraNaamJoker). My solution is create this Escaped mimic string and then convert it back to unicode (to avoid real Escaped Unicode restriction). I used it for copying text, so it is possible, that in uencode method will be better to use '\\u' except '\\\\u'. Try it.
/**

I had the same problem. This work fine for me:
str(objdata).encode('utf-8')
That data:image/png;base64
URL is cool, I’ve never run into it before. The long encrypted link is the actual image, i.e. no image call to the server. See RFC 2397 for details.
Side note: I have had trouble getting larger base64 images to render on IE8. I believe IE8 has a 32K limit that can be problematic for larger files. See this other StackOverflow thread for details.
I faced this issue, when I was supplying the executable folder with a, by the .exe requested DLL. In my case, the DLL I supplied to the .exe was searching for another necessary DLL which was not available. The searching DLL was not capable of telling that it can not find the necessary DLL.
You might check the DLLs you're loading and the dependencies of these DLL's.
When using latest WHM (v66.0.23) you may go to MultiPHP INI Editor choose PHP version and set session.save_path to default i.e. /var/cpanel/php/sessions/ea-php70 instead of previous simple tmp - this helped me to get rid of such errors.
Non of these solutions worked for me. I fixed it by temporarily changing the filename of C:\Windows\System32\java.exe
to java_.exe
Character U+201C Left Double Quotation Mark is not present in the Latin-1 (ISO-8859-1) encoding.
It is present in code page 1252 (Western European). This is a Windows-specific encoding that is based on ISO-8859-1 but which puts extra characters into the range 0x80-0x9F. Code page 1252 is often confused with ISO-8859-1, and it's an annoying but now-standard web browser behaviour that if you serve your pages as ISO-8859-1, the browser will treat them as cp1252 instead. However, they really are two distinct encodings:
>>> u'He said \u201CHello\u201D'.encode('iso-8859-1')
UnicodeEncodeError
>>> u'He said \u201CHello\u201D'.encode('cp1252')
'He said \x93Hello\x94'
If you are using your database only as a byte store, you can use cp1252 to encode “
and other characters present in the Windows Western code page. But still other Unicode characters which are not present in cp1252 will cause errors.
You can use encode(..., 'ignore')
to suppress the errors by getting rid of the characters, but really in this century you should be using UTF-8 in both your database and your pages. This encoding allows any character to be used. You should also ideally tell MySQL you are using UTF-8 strings (by setting the database connection and the collation on string columns), so it can get case-insensitive comparison and sorting right.
Interesting if maddening puzzle...but here's the best I could get:
The data seems to repeat every 8 bytes or so.
import struct
import base64
target = \
r'''Q5YACgAAAABDlgAbAAAAAEOWAC0AAAAAQ5YAPwAAAABDlgdNAAAAAEOWB18AAAAAQ5YH
[snip.]
ZAAAAABExxniAAAAAETH/rQAAAAARMf/MwAAAABEx/+yAAAAAETIADEAAAAA'''
data = base64.b64decode(target)
cleaned_data = []
struct_format = ">ff"
for i in range(len(data) // 8):
cleaned_data.append(struct.unpack_from(struct_format, data, 8*i))
That gives output like the following (a sampling of lines from the first 100 or so):
(300.00030517578125, 0.0)
(300.05975341796875, 241.93943786621094)

(328.34432983398438, 280.55218505859375)
That first number does seem to monotonically increase through the entire set. If you plot it:
import matplotlib.pyplot as plt
f, ax = plt.subplots()
ax.plot(*zip(*cleaned_data))
format = 'hhhh'
(possibly with various paddings/directions (e.g. '<hhhh'

Two things. First, you must base64 decode the mykey.pem
file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey
ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec
, which is based on the SubjectPublicKeyInfo
ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.
import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;
// ...
String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);
Don't hardcode the character encoding of your environment inside your script; print Unicode text directly instead:
assert isinstance(text, unicode) # or str on Python 3
print(text)
If your output is redirected to a file (or a pipe); you could use PYTHONIOENCODING
envvar, to specify the character encoding:
$ PYTHONIOENCODING=utf-8 python your_script.py >output.utf8
Otherwise, python your_script.py
should work as is -- your locale settings are used to encode the text (on POSIX check: LC_ALL
, LC_CTYPE
, LANG
envvars -- set LANG
to a utf-8 locale if necessary).
In Android M the top solution won't work. I've written a helper class to fix that which you should call from your Application class and all Activities (I would suggest creating a BaseActivity and then make all the Activities inherit from it.
Note: This will also support properly RTL layout direction.
Helper class:
public class LocaleUtils {
private static Locale sLocale;
public static void setLocale(Locale locale) {
sLocale = locale;
if(sLocale != null) {
Locale.setDefault(sLocale);
}
}
public static void updateConfig(ContextThemeWrapper wrapper) {
if(sLocale != null && Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
Configuration configuration = new Configuration();
configuration.setLocale(sLocale);
wrapper.applyOverrideConfiguration(configuration);
}
}
public static void updateConfig(Application app, Configuration configuration) {
if (sLocale != null && Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {
//Wrapping the configuration to avoid Activity endless loop
Configuration config = new Configuration(configuration);
// We must use the now-deprecated config.locale and res.updateConfiguration here,
// because the replacements aren't available till API level 24 and 17 respectively.
config.locale = sLocale;
Resources res = app.getBaseContext().getResources();
res.updateConfiguration(config, res.getDisplayMetrics());
}
}
}
Application:
public class App extends Application {
public void onCreate(){
super.onCreate();
LocaleUtils.setLocale(new Locale("iw"));
LocaleUtils.updateConfig(this, getBaseContext().getResources().getConfiguration());
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
LocaleUtils.updateConfig(this, newConfig);
}
}
BaseActivity:
public class BaseActivity extends Activity {
public BaseActivity() {
LocaleUtils.updateConfig(this);
}
}
You need to implement a custom Authenticator
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
class GMailAuthenticator extends Authenticator {
String user;
String pw;
public GMailAuthenticator (String username, String password)
{
super();
this.user = username;
this.pw = password;
}
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(user, pw);
}
}
Now use it in the Session
Session session = Session.getInstance(props, new GMailAuthenticator(username, password));

If you're running cPanel/WHM, make sure that IP is whitelisted in the firewall. You will als need to add that IP to the remote SQL IP list in the cPanel account you're trying to connect to.
I implemented this code in JavaScript using the HTML Canvas element, and it produced wonderful simulations at 60 frames per second. I started the simulation off with a collection of a dozen balls at random positions and velocities. I found that at higher velocities, a glancing collision between a small ball and a much larger one caused the small ball to appear to STICK to the edge of the larger ball, and moved up to around 90 degrees around the larger ball before separating. (I wonder if anyone else observed this behavior.)
Some logging of the calculations showed that the Minimum Translation Distance in these cases was not large enough to prevent the same balls from colliding in the very next time step. I did some experimenting and found that I could solve this problem by scaling up the MTD based on the relative velocities:
dot_velocity = ball_1.velocity.dot(ball_2.velocity);
mtd_factor = 1. + 0.5 * Math.abs(dot_velocity * Math.sin(collision_angle));
mtd.multplyScalar(mtd_factor);
I verified that before and after this fix, the total kinetic energy was conserved for every collision. The 0.5 value in the mtd_factor was the approximately the minumum value found to always cause the balls to separate after a collision.
Although this fix introduces a small amount of error in the exact physics of the system, the tradeoff is that now very fast balls can be simulated in a browser without decreasing the time step size.
This is Pythons way do show you unicode encoded strings. But i think you should be able to print the string on the screen or write it into a new file without any problems.

What happens
When the user views a form to create, update, or destroy a resource, the Rails app creates a random authenticity_token
, stores this token in the session, and places it in a hidden field in the form. When the user submits the form, Rails looks for the authenticity_token
, compares it to the one stored in the session, and if they match the request is allowed to continue.
Why it happens
Since the authenticity token is stored in the session, the client cannot know its value. This prevents people from submitting forms to a Rails app without viewing the form within that app itself.
Imagine that you are using service A, you logged into the service and everything is ok. Now imagine that you went to use service B, and you saw a picture you like, and pressed on the picture to view a larger size of it. Now, if some evil code was there at service B, it might send a request to service A (which you are logged into), and ask to delete your account, by sending a request to http://serviceA.com/close_account
. This is what is known as CSRF (Cross Site Request Forgery).
If service A is using authenticity tokens, this attack vector is no longer applicable, since the request from service B would not contain the correct authenticity token, and will not be allowed to continue.
API docs describes details about meta tag:
CSRF protection is turned on with the
protect_from_forgery
method, which checks the token and resets the session if it doesn't match what was expected. A call to this method is generated for new Rails applications by default. The token parameter is namedauthenticity_token
by default. The name and value of this token must be added to every layout that renders forms by includingcsrf_meta_tags
in the HTML head.
Notes
Keep in mind, Rails only verifies not idempotent methods (POST, PUT/PATCH and DELETE). GET request are not checked for authenticity token. Why? because the HTTP specification states that GET requests is idempotent and should not create, alter, or destroy resources at the server, and the request should be idempotent (if you run the same command multiple times, you should get the same result every time).
Also the real implementation is a bit more complicated as defined in the beginning, ensuring better security. Rails does not issue the same stored token with every form. Neither does it generate and store a different token every time. It generates and stores a cryptographic hash in a session and issues new cryptographic tokens, which can be matched against the stored one, every time a page is rendered. See request_forgery_protection.rb.
Lessons
Use authenticity_token
to protect your not idempotent methods (POST, PUT/PATCH, and DELETE). Also make sure not to allow any GET requests that could potentially modify resources on the server.
EDIT: Check the comment by @erturne regarding GET requests being idempotent. He explains it in a better way than I have done here.
Thought I'd simplify the simplest examples copied from above, working for me on Py3.6. Simplest is multiprocessing.Pool
:
import multiprocessing
import time
def worker(x):
time.sleep(1)
return x
pool = multiprocessing.Pool()
print(pool.map(worker, range(10)))
You can set the number of processes in the pool with, e.g., Pool(processes=5)
. However it defaults to CPU count, so leave it blank for CPU-bound tasks. (I/O-bound tasks often suit threads anyway, as the threads are mostly waiting so can share a CPU core.) Pool
also applies chunking optimization.
(Note that the worker method cannot be nested within a method. I initially defined my worker method inside the method that makes the call to pool.map
, to keep it all self-contained, but then the processes couldn't import it, and threw "AttributeError: Can't pickle local object outer_method..inner_method". More here. It can be inside a class.)
(Appreciate the original question specified printing 'represent!'
rather than time.sleep()
, but without it I thought some code was running concurrently when it wasn't.)
Py3's ProcessPoolExecutor
is also two lines (.map
returns a generator so you need the list()
):
from concurrent.futures import ProcessPoolExecutor
with ProcessPoolExecutor() as executor:
print(list(executor.map(worker, range(10))))
With plain Process
es:
import multiprocessing
import time
def worker(x, queue):
time.sleep(1)
queue.put(x)
queue = multiprocessing.SimpleQueue()
tasks = range(10)
for task in tasks:
multiprocessing.Process(target=worker, args=(task, queue,)).start()
for _ in tasks:
print(queue.get())
Use SimpleQueue
if all you need is put
and get
. The first loop starts all the processes, before the second makes the blocking queue.get
calls. I don't think there's any reason to call p.join()
too.
AFAIK, {...}
can only be used as a path, not inside a query-param. Try this instead:
public interface FooService {
@GET("/maps/api/geocode/json?sensor=false")
void getPositionByZip(@Query("address") String address, Callback<String> cb);
}
If you have an unknown amount of parameters to pass, you can use do something like this:
public interface FooService {
@GET("/maps/api/geocode/json")
@FormUrlEncoded
void getPositionByZip(@FieldMap Map<String, String> params, Callback<String> cb);
}
To allow cross domain:
about:config
security.fileuri.strict_origin_policy
in the search barYou can now close the tab. Normally you can now make cross domain request with this config.
See here for more details.
You can use truncate
one-liner below:
const text = "The string that I want to truncate!";_x000D_
_x000D_
const truncate = (str, len) => str.substring(0, (str + ' ').lastIndexOf(' ', len));_x000D_
_x000D_
console.log(truncate(text, 14));
_x000D_
I haven't tested it but it should work.
public double incassoMargherita()
{
double sum = 0;
for(int i = 0; i < m.size(); i++)
{
sum = sum + m.get(i);
}
return sum;
}
Generally, you just need to update constraints and call layoutIfNeeded
inside the animation block. This can be either changing the .constant
property of an NSLayoutConstraint
, adding remove constraints (iOS 7), or changing the .active
property of constraints (iOS 8 & 9).
[UIView animateWithDuration:0.3 animations:^{
// Move to right
self.leadingConstraint.active = false;
self.trailingConstraint.active = true;
// Move to bottom
self.topConstraint.active = false;
self.bottomConstraint.active = true;
// Make the animation happen
[self.view setNeedsLayout];
[self.view layoutIfNeeded];
}];
There are some questions about whether the constraint should be changed before the animation block, or inside it (see previous answers).
The following is a Twitter conversation between Martin Pilkington who teaches iOS, and Ken Ferry who wrote Auto Layout. Ken explains that though changing constants outside of the animation block may currently work, it's not safe and they should really be change inside the animation block. https://twitter.com/kongtomorrow/status/440627401018466305
Here's a simple project showing how a view can be animated. It's using Objective C and animates the view by changing the .active
property of several constraints.

I think this is a simple example, how to check if a radio in a group of radios was checked.
if($('input[name=html_elements]:checked').length){
//a radio button was checked
}else{
//there was no radio button checked
}
You can't assign a List<Number>
to a reference of type List<Integer>
because List<Number>
allows types of numbers other than Integer
. If you were allowed to do that, the following would be allowed:
List<Number> numbers = new ArrayList<Number>();
numbers.add(1.1); // add a double
List<Integer> ints = numbers;
Integer fail = ints.get(0); // ClassCastException!
The type List<Integer>
is making a guarantee that anything it contains will be an Integer
. That's why you're allowed to get an Integer
out of it without casting. As you can see, if the compiler allowed a List
of another type such as Number
to be assigned to a List<Integer>
that guarantee would be broken.
Assigning a List<Integer>
to a reference of a type such as List<?>
or List<? extends Number>
is legal because the ?
means "some unknown subtype of the given type" (where the type is Object
in the case of just ?
and Number
in the case of ? extends Number
).
Since ?
indicates that you do not know what specific type of object the List
will accept, it isn't legal to add anything but null
to it. You are, however, allowed to retrieve any object from it, which is the purpose of using a ? extends X
bounded wildcard type. Note that the opposite is true for a ? super X
bounded wildcard type... a List<? super Integer>
is "a list of some unknown type that is at least a supertype of Integer
". While you don't know exactly what type of List
it is (could be List<Integer>
, List<Number>
, List<Object>
) you do know for sure that whatever it is, an Integer
can be added to it.
Finally, new ArrayList<?>()
isn't legal because when you're creating an instance of a paramterized class like ArrayList
, you have to give a specific type parameter. You could really use whatever in your example (Object
, Foo
, it doesn't matter) since you'll never be able to add anything but null
to it since you're assigning it directly to an ArrayList<?>
reference.
With IIS's self-signed certificate feature, you cannot set the common name (CN) for the certificate, and therefore cannot create a certificate bound to your choice of subdomain.
One way around the problem is to use makecert.exe, which is bundled with the .Net 2.0 SDK. On my server it's at:
C:\Program Files\Microsoft.Net\SDK\v2.0 64bit\Bin\makecert.exe
You can create a signing authority and store it in the LocalMachine certificates repository as follows (these commands must be run from an Administrator account or within an elevated command prompt):
makecert.exe -n "CN=My Company Development Root CA,O=My Company,
OU=Development,L=Wallkill,S=NY,C=US" -pe -ss Root -sr LocalMachine
-sky exchange -m 120 -a sha1 -len 2048 -r
You can then create a certificate bound to your subdomain and signed by your new authority:
(Note that the the value of the -in parameter must be the same as the CN value used to generate your authority above.)
makecert.exe -n "CN=subdomain.example.com" -pe -ss My -sr LocalMachine
-sky exchange -m 120 -in "My Company Development Root CA" -is Root
-ir LocalMachine -a sha1 -eku 1.3.6.1.5.5.7.3.1
Your certificate should then appear in IIS Manager to be bound to your site as explained in Tom Hall's post.

I'd go for semantic markup, use an <hr/>

Unless it's just a border what you want, then you can use a combination of padding, border and margin, to get the desired bound.
UNIX filesystems (generally) don't store creation times. Instead, there are only access time, (data) modification time, and (inode) change time.
That being said, find
has -atime
-mtime
-ctime
predicates:
$ man 1 find ... -ctime n The primary shall evaluate as true if the time of last change of file status information subtracted from the initialization time, divided by 86400 (with any remainder discarded), is n. ...
Thus find -ctime 0
finds everything for which the inode has changed (e.g. includes file creation, but also counts link count and permissions and filesize change) less than an hour ago.
The optimizer should be smart enough to give you the same result either way for normal queries. Check the execution plan and they should give you the same thing. If they don't, I would normally consider the JOIN to be faster. All systems are different, though, so you should profile the code on your system to be sure.
Use s1.equalsIgnoreCase(s2)

Just want to follow up on the great answer from Paolo Moretti and Browserify. If you are using a transpiler (e.g., babel, typescript) and you have separate folders for source and transpiled code like src/
and dist/
, you could use a variation of the solutions as
With the following directory structure:
app
node_modules
... // normal npm dependencies for app
src
node_modules
app
... // source code
dist
node_modules
app
... // transpiled code
you can then let babel etc to transpile src
directory to dist
directory.
Using symlink we can get rid some levels of nesting:
app
node_modules
... // normal npm dependencies for app
src
node_modules
app // symlinks to '..'
... // source code
dist
node_modules
app // symlinks to '..'
... // transpiled code
A caveat with babel --copy-files The --copy-files
flag of babel
does not deal with symlinks well. It may keep navigating into the ..
symlink and recusively seeing endless files. A workaround is to use the following directory structure:
app
node_modules
app // symlink to '../src'
... // normal npm dependencies for app
src
... // source code
dist
node_modules
app // symlinks to '..'
... // transpiled code
In this way, code under src
will still have app
resolved to src
, whereas babel would not see symlinks anymore.
Try using setAttribute
instead:
document.getElementById('img')
.setAttribute(
'src', 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='
);
Real answer: (And make sure you remove the line-breaks in the base64.)
I have been playing around flexbox lately and i came to solution for this through experimentation and the following reasoning. However, in reality I'm not sure if this is exactly what happens.
If real width is affected by flex system. So after width of elements hit max width of parent they extra width set in css is ignored. Then it's safe to set width to 100%.
Since height of img tag is derived from image itself then setting height to 0% could do something. (this is where i am unclear as to what...but it made sense to me that it should fix it)
(remember saw it here first!)
.slider {
display: flex;
}
.slider img {
height: 0%;
width: 100%;
margin: 0 5px;
}
Works only in chrome yet
All the above solutions are quite large, i wanted to give my 2 cents on this.
I am only checking if the value inputed is a number or not, and checking if it's not blank, that's all.
Here is the html:
<input type="text" ng-keypress="CheckNumber()"/>
Here is the JS:
$scope.CheckKey = function () {
if (isNaN(event.key) || event.key === ' ' || event.key === '') {
event.returnValue = '';
}
};
It's quite simple.
I belive this wont work on Paste tho, just so it's known.
For Paste, i think you would need to use the onChange event and parse the whole string, quite another beast the tamme. This is specific for typing.
UPDATE for Paste: just add this JS function:
$scope.CheckPaste = function () {
var paste = event.clipboardData.getData('text');
if (isNaN(paste)) {
event.preventDefault();
return false;
}
};
And the html input add the trigger:
<input type="text" ng-paste="CheckPaste()"/>
I hope this helps o/
You can easily reach them by using the Run window and entering:

(WHEN .wsdl is referring to .xsd/schemas using import) If you're using the WMB Tooklit (v8.0.0.4 WMB) then you can find .xsd using following steps :
Create library (optional) > Right Click , New Message Model File > Select SOAP XML > Choose Option 'I already have WSDL for my data' > 'Select file outside workspace' > 'Select the WSDL bindings to Import' (if there are multiple) > Finish.
This will give you the .xsd and .wsdl files in your Workspace (Application Perspective).
There are indeed global variables in javascript. You can learn more about scopes, which are helpful in this situation.
Your code could look like this:
<script>
var count = 1;
function setColor(btn, color) {
var property = document.getElementById(btn);
if (count == 0) {
property.style.backgroundColor = "#FFFFFF"
count = 1;
}
else {
property.style.backgroundColor = "#7FFF00"
count = 0;
}
}
</script>
Hope this helps.
I usually use Task
to interact with Winforms and simple background worker to make it not freezing the UI. here an example when I prefer using Task
private async void buttonDownload_Click(object sender, EventArgs e)
{
buttonDownload.Enabled = false;
await Task.Run(() => {
using (var client = new WebClient())
{
client.DownloadFile("http://example.com/file.mpeg", "file.mpeg");
}
})
buttonDownload.Enabled = true;
}
VS
private void buttonDownload_Click(object sender, EventArgs e)
{
buttonDownload.Enabled = false;
Thread t = new Thread(() =>
{
using (var client = new WebClient())
{
client.DownloadFile("http://example.com/file.mpeg", "file.mpeg");
}
this.Invoke((MethodInvoker)delegate()
{
buttonDownload.Enabled = true;
});
});
t.IsBackground = true;
t.Start();
}
the difference is you don't need to use MethodInvoker
and shorter code.
Your understanding is correct. I wonder why you don't see any advantages in ContextLoaderListener. For example, you need to build a session factory (to manage database). This operation can take some time, so it's better to do it on startup. Of course you can do it with init servlets or something else, but the advantage of Spring's approach is that you make configuration without writing code.
In case you want to deeply iterate into a complex (nested) object for each key & value, you can do so using Object.keys(), recursively:
const iterate = (obj) => {
Object.keys(obj).forEach(key => {
console.log(`key: ${key}, value: ${obj[key]}`)
if (typeof obj[key] === 'object') {
iterate(obj[key])
}
})
}
We store latitude/longitude X 1,000,000 in our oracle database as NUMBERS to avoid round off errors with doubles.
Given that latitude/longitude to the 6th decimal place was 10 cm accuracy that was all we needed. Many other databases also store lat/long to the 6th decimal place.
This is a late addition but I was looking for information on the scale function myself and though it might help somebody else as well.
To modify the response from Ricardo Saporta a little bit.
Scaling is not done using standard deviation, at least not in version 3.6.1 of R, I base this on "Becker, R. (2018). The new S language. CRC Press." and my own experimentation.
X.man.scaled <- X/sqrt(sum(X^2)/(length(X)-1))
X.aut.scaled <- scale(X, center = F)
The result of these rows are exactly the same, I show it without centering because of simplicity.
I would respond in a comment but did not have enough reputation.
Apparently the question poorly describes the OP's problem, but this question is the top search result for dragging to reorder table rows, so that is what I will answer. I wasn't interested in bringing in jQuery UI for something so simple, so here is a jQuery only solution:
$(".grab").mousedown(function(e) {
var tr = $(e.target).closest("TR"),
si = tr.index(),
sy = e.pageY,
b = $(document.body),
drag;
if (si == 0) return;
b.addClass("grabCursor").css("userSelect", "none");
tr.addClass("grabbed");
function move(e) {
if (!drag && Math.abs(e.pageY - sy) < 10) return;
drag = true;
tr.siblings().each(function() {
var s = $(this),
i = s.index(),
y = s.offset().top;
if (i > 0 && e.pageY >= y && e.pageY < y + s.outerHeight()) {
if (i < tr.index())
tr.insertAfter(s);
else
tr.insertBefore(s);
return false;
}
});
}
function up(e) {
if (drag && si != tr.index()) {
drag = false;
alert("moved!");
}
$(document).unbind("mousemove", move).unbind("mouseup", up);
b.removeClass("grabCursor").css("userSelect", "none");
tr.removeClass("grabbed");
}
$(document).mousemove(move).mouseup(up);
});

.grab {
cursor: grab;

ignores the first row, which for me contains TH

with your "drag finished" logic.
You just do this:
final private WebElement input = driver.findElement(By.id("myId"));
input.clear();
input.sendKeys(value); // The value we want to set to input
input.sendKeys(Keys.RETURN);
Java's URI Class can help you out of this:
public static String getCurrentUrl(HttpServletRequest request){
URL url = new URL(request.getRequestURL().toString());
String host = url.getHost();
String userInfo = url.getUserInfo();
String scheme = url.getProtocol();
String port = url.getPort();
String path = request.getAttribute("javax.servlet.forward.request_uri");
String query = request.getAttribute("javax.servlet.forward.query_string");
URI uri = new URI(scheme,userInfo,host,port,path,query,null)
return uri.toString();
}
Use the ssh2
functions. Anything you'd do via an exec() call can be done directly using these functions, saving you a lot of connections and shell invocations.
My problem was that there was a parent style with position: absolute !important
which I was not allowed to edit.
So I gave my specific checkbox position: relative !important
and it fixed the vertical misalignment issue.
To answer a little more conceptually:
SelectedValuePath
defines which property (by its name) of the objects bound to the ListBox's ItemsSource
will be used as the item's SelectedValue
.
For example, if your ListBox is bound to a collection of Person
objects, each of which has Name
, Age
, and Gender
properties, SelectedValuePath=Name
will cause the value of the selected Person
's Name
property to be returned in SelectedValue
.
Note that if you override the ListBox's ControlTemplate (or apply a Style) that specifies what property should display, SelectedValuePath
cannot be used.
SelectedItem
, meanwhile, returns the entire Person
object currently selected.
(Here's a further example from MSDN, using TreeView)
Update: As @Joe pointed out, the DisplayMemberPath property is unrelated to the Selected* properties. Its proper description follows:
Note that these values are distinct from DisplayMemberPath
(which is defined on ItemsControl, not Selector), but that property has similar behavior to SelectedValuePath
: in the absence of a style/template, it identifies which property of the object bound to item should be used as its string representation.
Assembling one INSERT
statement with multiple rows is much faster in MySQL than one INSERT
statement per row.
That said, it sounds like you might be running into string-handling problems in PHP, which is really an algorithm problem, not a language one. Basically, when working with large strings, you want to minimize unnecessary copying. Primarily, this means you want to avoid concatenation. The fastest and most memory efficient way to build a large string, such as for inserting hundreds of rows at one, is to take advantage of the implode()
function and array assignment.
$sql = array();
foreach( $data as $row ) {
$sql[] = '("'.mysql_real_escape_string($row['text']).'", '.$row['category_id'].')';
}
mysql_query('INSERT INTO table (text, category) VALUES '.implode(',', $sql));
The advantage of this approach is that you don't copy and re-copy the SQL statement you've so far assembled with each concatenation; instead, PHP does this once in the implode()
statement. This is a big win.
If you have lots of columns to put together, and one or more are very long, you could also build an inner loop to do the same thing and use implode()
to assign the values clause to the outer array.
Uninstalling all C++ redistributables and unchecking the C++ option worked for me. Note that I have VS2010 SP1, and VS2012 installed already.
This error can be resolved by adding MessageBoxOptions.ServiceNotification
.
MessageBox.Show(msg, "Print Error", System.Windows.Forms.MessageBoxButtons.YesNo,
System.Windows.Forms.MessageBoxIcon.Error,
System.Windows.Forms.MessageBoxDefaultButton.Button1,
System.Windows.Forms.MessageBoxOptions.ServiceNotification);
But it is not going to show any dialog box if your web application is installed on IIS or server.Because in IIS or server it is hosted on worker process which dont have any desktop.
Ok well this might work for you, a function that takes a path and returns an array of file names in the folder. You could use an if statement to get just the excel files when looping through the array.
Function listfiles(ByVal sPath As String)
Dim vaArray As Variant
Dim i As Integer
Dim oFile As Object
Dim oFSO As Object
Dim oFolder As Object
Dim oFiles As Object
Set oFSO = CreateObject("Scripting.FileSystemObject")
Set oFolder = oFSO.GetFolder(sPath)
Set oFiles = oFolder.Files
If oFiles.Count = 0 Then Exit Function
ReDim vaArray(1 To oFiles.Count)
i = 1
For Each oFile In oFiles
vaArray(i) = oFile.Name
i = i + 1
Next
listfiles = vaArray
End Function
It would be nice if we could just access the files in the files object by index number but that seems to be broken in VBA for whatever reason (bug?).
It was due to IE Document-mode version too low. Press 'F12' and using higher version( My case, above version 9 is OK)
A simple 4on4 pasting function that works-
def paste(background,foreground,pos=(0,0)):
#get position and crop pasting area if needed
x = pos[0]
y = pos[1]

bgHeight = background.shape[1]
frWidth = foreground.shape[0]
frHeight = foreground.shape[1]
width = bgWidth-x
height = bgHeight-y
if frWidth<width:
width = frWidth
if frHeight<height:
height = frHeight
# normalize alpha channels from 0-255 to 0-1
alpha_background = background[x:x+width,y:y+height,3] / 255.0
alpha_foreground = foreground[:width,:height,3] / 255.0
# set adjusted colors
for color in range(0, 3):
fr = alpha_foreground * foreground[:width,:height,color]
bg = alpha_background * background[x:x+width,y:y+height,color] * (1 - alpha_foreground)
background[x:x+width,y:y+height,color] = fr+bg
# set adjusted alpha and denormalize back to 0-255
background[x:x+width,y:y+height,3] = (1 - (1 - alpha_foreground) * (1 - alpha_background)) * 255

In SSMS, "Query" menu item... "Results to"... "Results to File"
Shortcut = CTRL+shift+F
You can set it globally too
"Tools"... "Options"... "Query Results"... "SQL Server".. "Default destination" drop down
Edit: after comment
In SSMS, "Query" menu item... "SQLCMD" mode
This allows you to run "command line" like actions.

If you are creating an array whose main feature is it's length, rather than the value of each index, defining an array as var a=Array(length);
is appropriate.
eg-
String.prototype.repeat= function(n){
n= n || 1;
return Array(n+1).join(this);
}
Create a function that addresses all the whitespace possibilites and enable only those that seem appropriate:

DECLARE @ShowWhiteSpace varchar(8000);
SET @ShowWhiteSpace = @str
SET @ShowWhiteSpace = REPLACE( @ShowWhiteSpace, CHAR(32), '[?]')
SET @ShowWhiteSpace = REPLACE( @ShowWhiteSpace, CHAR(13), '[CR]')

This is solved for me when I update maven and check the option "Force update of Snapshots/Releases" in Eclipse. this clears all errors. So right click on project -> Maven -> update project, then check the above option -> Ok. Hope this helps you.
For guys like me, who aren't minimalistic, there is a PECL extension called "intl". I use it for idn conversion since it works way better than the "idn" extension and some other n1 classes like "IntlDateFormatter".
Well, what I want to say is, the "intl" extension has a class called "IntlCalendar" which can handle many international countries (e.g. in Saudi Arabia, sunday is not a weekend day). The IntlCalendar has a method IntlCalendar::isWeekend for that. Maybe you guys give it a shot, I like that "it works for almost every country" fact on these intl-classes.
EDIT: Not quite sure but since PHP 5.5.0, the intl extension is bundled with PHP (--enable-intl).
I created a 2 prototype to handle this for me, one for a number, and one for a String.
// This is a safety check to make sure the prototype is not already defined.
Function.prototype.method = function (name, func) {
if (!this.prototype[name]) {
this.prototype[name] = func;
return this;
}
};
// returns the int value or -1 by default if it fails
Number.method('tryParseInt', function (defaultValue) {
return parseInt(this) == this ? parseInt(this) : (defaultValue === undefined ? -1 : defaultValue);
});
// returns the int value or -1 by default if it fails
String.method('tryParseInt', function (defaultValue) {
return parseInt(this) == this ? parseInt(this) : (defaultValue === undefined ? -1 : defaultValue);
});
If you dont want to use the safety check, use
String.prototype.tryParseInt = function(){
/*Method body here*/
};
Number.prototype.tryParseInt = function(){
/*Method body here*/
};
Example usage:
var test = 1;
console.log(test.tryParseInt()); // returns 1
var test2 = '1';
console.log(test2.tryParseInt()); // returns 1
var test3 = '1a';
console.log(test3.tryParseInt()); // returns -1 as that is the default
var test4 = '1a';
console.log(test4.tryParseInt(0));// returns 0, the specified default value
You can use keyboard short-cut for Description/ detailed information of Table in SQL Server 2008
.
It will show detailed information/ description of mentioned table as,
1) Table created date,
2) Columns Description,
3) Identity,
4) Indexes,
5) Constraints,
6) References etc. As shown Below [example]:
Enabling SQL Server Service Broker requires a database lock. Stop the SQL Server Agent and then execute the following:
USE master ;
GO
ALTER DATABASE [MyDatabase] SET ENABLE_BROKER ;
GO
Change [MyDatabase] with the name of your database in question and then start SQL Server Agent.
If you want to see all the databases that have Service Broker enabled or disabled, then query sys.databases, for instance:
SELECT
name, database_id, is_broker_enabled
FROM sys.databases
You really want to use at. It is exactly made for this purpose.
echo /usr/bin/the_command options | at now + 1 day
However if you don't have at, or your hosting company doesn't provide access to it, you could make a self-deleting cron entry.
Sadly, this will remove all your cron entries. However, if you only have one, this is fine.
0 0 2 12 * crontab -r ; /home/adm/bin/the_command options
The command crontab -r
removes your crontab entry. Luckily the rest of the command line will still execute.
WARNING: This is dangerous! It removes ALL cron entries. If you have many, this will remove them all, not just the one that has the "crontab -r" line!
I can see some people have asked, so on OSX you can still go to navigate->test or use cmd+shift+T
Remember you have to be focused in the class for this to work
As mentioned in the error, the official manual and the comments:
Replace
public function TSStatus($host, $queryPort)
with
public function __construct($host, $queryPort)
First, you'll need to add session_start()
at the top of any page that you wish to use SESSION
variables on.
Also, you should check to make sure the variable is set first before using it:
if(isset($_SESSION['SESS_fname'])){
echo $_SESSION['SESS_fname'];
}
Or, simply:
echo (isset($_SESSION['SESS_fname']) ? $_SESSION['SESS_fname'] : "Visitor");
You could skip the jquery and just use CSS style tagging:
<ul>
<li>India</li>
<li>Indonesia</li>
<li style="background-color:#343434;">China</li>
<li>United States</li>
<li>United Kingdom</li>
</ul>

The exec(3,3p)

If you use HashSet
instead of List
for listofGenres
you can do:
var genres = new HashSet<Genre>() { "action", "comedy" };
var movies = _db.Movies.Where(p => genres.Overlaps(p.Genres));
Do this, it will work.

I wrote this KalmanLocationManager for Android, which wraps the two most common location providers, Network and GPS, kalman-filters the data, and delivers updates to a LocationListener
(like the two 'real' providers).
I use it mostly to "interpolate" between readings - to receive updates (position predictions) every 100 millis for instance (instead of the maximum gps rate of one second), which gives me a better frame rate when animating my position.
Actually, it uses three kalman filters, on for each dimension: latitude, longitude and altitude. They're independent, anyway.
This makes the matrix math much easier: instead of using one 6x6 state transition matrix, I use 3 different 2x2 matrices. Actually in the code, I don't use matrices at all. Solved all equations and all values are primitives (double).
The source code is working, and there's a demo activity. Sorry for the lack of javadoc in some places, I'll catch up.
Javascript String objects have a split function, doesn't really need to be jQuery specific
var str = "nice.test"
var strs = str.split(".")
strs would be
["nice", "test"]
I'd be tempted to use JSON in your example though. The php could return the JSON which could easily be parsed
success: function(data) {
var items = JSON.parse(data)
}
If you haven't commit the local changes yet since the last pull/clone, you can use:
git checkout *
git pull
checkout
will clear your local changes with the last local commit, and
pull
will sincronize it to the remote repository
To elaborate on @serine's answer and illustrate working with non-trivial multi-valued condition: I had a need to show a "dim-out" overlay on an item for the boolean condition NOT a AND (b OR NOT c)
.
For background, this is a "Multiple Choice" question. If the user picks a wrong answer it becomes disabled (dimmed out and cannot be selected again). An automated agent has the ability to focus on any particular choice to give an explanation (border highlighted). When the agent focuses on an item, it should not be dimmed out even if it is disabled. All items that are not in focused are marked de-focused, and should be dimmed out.
The logic for dimming is thus:
NOT IsFocused AND (IsDefocused OR NOT Enabled)
To implement this logic, I made a generic IMultiValueConverter
named (awkwardly) to match my logic
// 'P' represents a parenthesis
// ! a && ( b || ! c )
class NOT_a_AND_P_b_OR_NOT_c_P : IMultiValueConverter
{
// redacted [...] for brevity
public object Convert(object[] values, ...)
{
bool a = System.Convert.ToBoolean(values[0]);
bool b = System.Convert.ToBoolean(values[1]);
bool c = System.Convert.ToBoolean(values[2]);
return !a && (b || !c);
}
...
}
In the XAML I use this in a MultiDataTrigger
in a <Style><Style.Triggers>
resource
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<!-- when the equation is TRUE ... -->
<Condition Value="True">
<Condition.Binding>
<MultiBinding Converter="{StaticResource NOT_a_AND_P_b_OR_NOT_c_P}">
<!-- NOT IsFocus AND ( IsDefocused OR NOT Enabled ) -->
<Binding Path="IsFocus"/>
<Binding Path="IsDefocused" />
<Binding Path="Enabled" />
</MultiBinding>
</Condition.Binding>
</Condition>
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<!-- ... show the 'dim-out' overlay -->
<Setter Property="Visibility" Value="Visible" />
</MultiDataTrigger.Setters>
</MultiDataTrigger>
And for completeness sake, my converter is defined in a ResourceDictionary
<ResourceDictionary xmlns:conv="clr-namespace:My.Converters" ...>
<conv:NOT_a_AND_P_b_OR_NOT_c_P x:Key="NOT_a_AND_P_b_OR_NOT_c_P" />
</ResourceDictionary>

Writeup with pictures about installing SQL Server
How to select a local server:
When you are asked to connect to a 'database server' right when you open up SQL Server Management Studio do this:
1) Make sure you have Server Type: Database
2) Make sure you have Authentication: Windows Authentication (no username & password)
3) For the server name field look to the right and select the drop down arrow, click 'browse for more'
4) New window pops up 'Browse for Servers', make sure to pick 'Local Servers' tab and under 'Database Engine' you will have the local server you set up during installation of SQL Server 14
How do I create a local database inside of Microsoft SQL Server 2014?
1) After you have connected to a server, bring up the Object Explorer toolbar under 'View' (Should open by default)
2) Now simply right click on 'Databases' and then 'Create new Database' to be taken through the database creation tools!
Try using the WebConfigurationManager class instead. For example:
string userName = WebConfigurationManager.AppSettings["PFUserName"]
This code works even faster (two 1.5 faster than my previous version):
public List<String> GetUserGroups(WindowsIdentity identity)
{
List<String> groups = new List<String>();
String userName = identity.Name;
int pos = userName.IndexOf(@"\");
if (pos > 0) userName = userName.Substring(pos + 1);
PrincipalContext domain = new PrincipalContext(ContextType.Domain, "riomc.com");
UserPrincipal user = UserPrincipal.FindByIdentity(domain, IdentityType.SamAccountName, userName); // NGeodakov
DirectoryEntry de = new DirectoryEntry("LDAP://RIOMC.com");
DirectorySearcher search = new DirectorySearcher(de);
search.Filter = "(&(objectClass=group)(member=" + user.DistinguishedName + "))";
search.PropertiesToLoad.Add("cn");
search.PropertiesToLoad.Add("samaccountname");
search.PropertiesToLoad.Add("memberOf");
SearchResultCollection results = search.FindAll();
foreach (SearchResult sr in results)
{
GetUserGroupsRecursive(groups, sr, de);
}
return groups;
}
public void GetUserGroupsRecursive(List<String> groups, SearchResult sr, DirectoryEntry de)
{
if (sr == null) return;
String group = (String)sr.Properties["cn"][0];
if (String.IsNullOrEmpty(group))
{
group = (String)sr.Properties["samaccountname"][0];
}
if (!groups.Contains(group))
{
groups.Add(group);
}
DirectorySearcher search;
SearchResult sr1;
String name;
int equalsIndex, commaIndex;
foreach (String dn in sr.Properties["memberof"])
{
equalsIndex = dn.IndexOf("=", 1);
if (equalsIndex > 0)
{
commaIndex = dn.IndexOf(",", equalsIndex + 1);
name = dn.Substring(equalsIndex + 1, commaIndex - equalsIndex - 1);
search = new DirectorySearcher(de);
search.Filter = "(&(objectClass=group)(|(cn=" + name + ")(samaccountname=" + name + ")))";
search.PropertiesToLoad.Add("cn");
search.PropertiesToLoad.Add("samaccountname");

Newest version of C# - C# 7.1 allows to create async console app. To enable C# 7.1 in project, you have to upgrade your VS to at least 15.3, and change C# version to C# 7.1
or C# latest minor version
. To do this, go to Project properties -> Build -> Advanced -> Language version.
After this, following code will work:
internal class Program
{
public static async Task Main(string[] args)
{
(...)
}
You can get equal height columns in CSS by applying bottom padding of a large amount, bottom negative margin of the same amount and surrounding the columns with a div that has overflow hidden. Vertically centering the text is a little trickier but this should help you on the way.

I think it worth mentioning that the previous answer by streetpc has invalid html, the doctype is XHTML and there are single quotes around the attributes. Also worth noting is that you dont need an extra element with clear
on in order to clear the internal floats of the container. If you use overflow hidden this clears the floats in all non-IE browsers and then just adding something to give hasLayout such as width or zoom:1 will cause IE to clear its internal floats.
I have tested this in all modern browsers FF3+ Opera9+ Chrome Safari 3+ and IE6/7/8. It may seem like an ugly trick but it works well and I use it in production a lot.
I hope this helps.
I had a hard time trying to figure this out on Xamarin. From the suggestions above I came up with this solution.
private string getRealPathFromURI(Android.Net.Uri contentUri)

string filename = "";
string thepath = "";
Android.Net.Uri filePathUri;
ICursor cursor = this.ContentResolver.Query(contentUri, null, null, null, null);
if (cursor.MoveToFirst())
{
int column_index = cursor.GetColumnIndex(MediaStore.Images.Media.InterfaceConsts.Data);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
filePathUri = Android.Net.Uri.Parse(cursor.GetString(column_index));
filename = filePathUri.LastPathSegment;
thepath = filePathUri.Path;
}
return thepath;
}

to false tells git to ignore any executable bit changes on the filesystem so it won't view this as a change. If you do need to stage an executable bit change for this repository anytime in the future, you would have to do it manually, or set core.filemode
back to true.
A less consequential alternative, if all the modified files should have mode 100755, is to do something like
chmod 100755 $(git ls-files --modified)
which just does exactly the change in mode, no more, no less, without additional implications.
(in my case, it was due to a OneDrive sync with my filesystem on MacOS; by not changing core.filemode
, I'm leaving the possibility open that the mode change might happen again in the future; in my case, I'd like to know if it happens again, and changing core.filemode
will hide it from me, which I don't want)
Try this way..
public static HttpContext getCurrentSession()
{
HttpContext.Current = new HttpContext(new HttpRequest("", ConfigurationManager.AppSettings["UnitTestSessionURL"], ""), new HttpResponse(new System.IO.StringWriter()));
System.Web.SessionState.SessionStateUtility.AddHttpSessionStateToContext(
HttpContext.Current, new HttpSessionStateContainer("", new SessionStateItemCollection(), new HttpStaticObjectsCollection(), 20000, true,
HttpCookieMode.UseCookies, SessionStateMode.InProc, false));
return HttpContext.Current;
}
I think if you closed a program
taskkill /f /im "winamp.exe"
//....(winamp.exe is example)...
end, so if you want to start a program that you can use
start "" /normal winamp.exe
(/norma,/max/min are that process value cpu)
ALSO
if you want command line without openning an new window you write that
/B is Start application without creating a new window. The application has ^C handling ignored. Unless the application enables ^C processing, ^Break is the only way to interrupt the application.

Who are you trying to convince? Engineers or manager? If you are trying to convince your engineer co-workers I think your best bet is to appeal to their desire to make a high quality piece of software. There are numerous studies that show it finds bugs, and if they care about doing a good job, that should be enough for them.
If you are trying to convince management, you will most likely have to do some kind of cost/benefit reasoning saying that the cost of the defects that will be undetected is greater than the cost of writing the tests. Be sure to include intagable costs too, such as loss of customer confidence, etc.
From angular's documentation,
ng-init SHOULD NOT be used for any initialization. It should be used only for aliasing. https://docs.angularjs.org/api/ng/directive/ngInit
onload should be used if any expression needs to be evaluated after a partial view is loaded (by ng-include). https://docs.angularjs.org/api/ng/directive/ngInclude
The major difference between them is when used with ng-include.
<div ng-include="partialViewUrl" onload="myFunction()"></div>
In this case, myFunction is called everytime the partial view is loaded.
<div ng-include="partialViewUrl" ng-init="myFunction()"></div>
Whereas, in this case, myFunction is called only once when the parent view is loaded.
I assume you're trying to tunnel into some unix box.
Make sure X11 forwarding is enabled in your PuTTY settings.
Here https://toddmotto.com/mastering-the-module-pattern you can find the pattern thoroughly explained. I would add that the second thing about modular JavaScript is how to structure your code in multiple files. Many folks may advice you here to go with AMD, yet I can say from experience that you will end up on some point with slow page response because of numerous HTTP requests. The way out is pre-compilation of your JavaScript modules (one per file) into a single file following CommonJS standard. Take a look at samples here http://dsheiko.github.io/cjsc/
A static block executes once in the life cycle of any program, another property of static block is that it executes before the main method.
used this code for src
$(this).attr("src", urlAbsolute);
I think this is easier:
double time = 200.3456;
DecimalFormat df = new DecimalFormat("#.##");
time = Double.valueOf(df.format(time));
System.out.println(time); // 200.35
Note that this will actually do the rounding for you, not just formatting.
Oh My Goodness! Look at the size of my temporary table space! Or... how to shrink temporary tablespaces in Oracle.
Yes I ran a query to see how big my temporary tablespace is:
SQL> SELECT tablespace_name, file_name, bytes
2 FROM dba_temp_files WHERE tablespace_name like 'TEMP%';
TABLESPACE_NAME FILE_NAME BYTES
----------------- -------------------------------- --------------
TEMP /the/full/path/to/temp01.dbf 13,917,200,000
The first question you have to ask is why the temporary tablespace is so large. You may know the answer to this off the top of your head. It may be due to a large query that you just run with a sort that was a mistake (I have done that more than once.) It may be due to some other exceptional circumstance. If that is the case then all you need to do to clean up is to shrink the temporary tablespace and move on in life.
But what if you don't know? Before you decide to shrink you may need to do some investigation into the causes of the large tablespace. If this happens on a regular basis then it is possible that your database just needs that much space.
The dynamic performance view
V$TEMPSEG_USAGE
can be very useful in determining the cause.
Maybe you just don't care about the cause and you just need to shrink it. This is your third day on the job. The data in the database is only 200MiB if data and the temporary tablespace is 13GiB - Just shrink it and move on. If it grows again then we will look into the cause. In the mean time I am out of space on that disk volume and I just need the space back.
Let's take a look at shrinking it. It will depend a little on what version
of Oracle you are running and how the temporary tablespace was set up.
Oracle will do it's best to keep you from making any horrendous mistakes
so we will just try the commands and if they don't work we will shrink
in a new way.
First let's try to shrink the datafile. If we can do that then we get back the space and we can worry about why it grew tomorrow.
SQL>
SQL> alter database tempfile '/the/full/path/to/temp01.dbf' resize 256M;
alter database tempfile '/the/full/path/to/temp01.dbf' resize 256M
*
ERROR at line 1:
ORA-03297: file contains used data beyond requested RESIZE value
Depending on the error message you may want to try this with different sizes that are smaller than the current site of the file. I have had limited success with this. Oracle will only shrink the file if the temporary tablespace is at the head of the file and if it is smaller than the size you specify. Some old Oracle documentation (they corrected this) said that you could issue the command and the error message would tell you what size you could shrink to. By the time I started working as a DBA this was not true. You just had to guess and re-run the command a bunch of times and see if it worked.
Alright. That didn't work. How about this.
SQL> alter tablespace YOUR_TEMP_TABLESPACE_NAME shrink space keep 256M;
If you are in 11g (Maybee in 10g too) this is it! If it works you may want to go back to the previous command and give it some more tries.
But what if that fails. If the temporary tablespace is the default temporary that was set up when the database was installed then you may need to do a lot more work. At this point I usually re-evaluate if I really need that space back. After all disk space only costs $X.XX a GiB. Usually I don't want to make changes like this during production hours. That means working at 2AM AGAIN! (Not that I really object to working at 2AM - it is just that... Well I like to sleep too. And my wife likes to have me at home at 2AM... not roaming the downtown streets at 4AM trying to remember where I parked my car 3 hours earlier. I have heard of that "telecommuting" thing. I just worry that I will get half way through and then my internet connectivity will fail - then I have to rush downtown to fix it all before folks show up in the morning to use the database.)
Ok... Back to the serious stuff... If the temporary tablespace you want to shrink is your default temporary tablespace, you will have to first create a new temporary tablespace, set it as the default temporary tablespace then drop your old default temporary tablespace and recreate it. Afterwords drop the second temporary table created.

Since, I test more times this script more useful by 1 million records each page 100 records with pagination work faster my PC execute this script 0 sec while compare with mysql have own limit and offset about 4.5 sec to get the result.
Someone may miss understanding Row_Number() always sort by specific field. In case we need to define only row in sequence should use:
SELECT TOP {LIMIT} * FROM (
SELECT TOP {LIMIT} + {OFFSET} ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) AS ROW_NO,*
FROM {TABLE_NAME}
) XX WHERE ROW_NO > {OFFSET}
Explain:
length(unique(df$col))
is the most simple way I can see.
public class SwapElements {
public static void main(String[] args) {
int[] arr1 = new int[5];
int[] arr2 = {10,20,30,40};
System.out.println("arr1 Before Swapping " + Arrays.toString(arr1));
System.out.println("arr2 Before Swapping " + Arrays.toString(arr2));
int temp[];
arr1[3] = 5;
arr1[0] = 2;
arr1[1] = 3;
arr1[2] = 6;
arr1[4] = 10;
temp = arr1;
arr1 = arr2;
arr2 = temp;
System.out.println("arr1 after Swapping " + Arrays.toString(arr1));
System.out.println("arr2 after Swapping " + Arrays.toString(arr2));
}
}
You can use async/await
for this. I would explain more, but there's nothing really to it. It's just a regular for
loop but I added the await
keyword before the construction of your Promise
What I like about this is your Promise can resolve a normal value instead of having a side effect like your code (or other answers here) include. This gives you powers like in The Legend of Zelda: A Link to the Past where you can affect things in both the Light World and the Dark World – ie, you can easily work with data before/after the Promised data is available without having to resort to deeply nested functions, other unwieldy control structures, or stupid IIFEs.
// where DarkWorld is in the scary, unknown future
// where LightWorld is the world we saved from Ganondorf
LightWorld ... await DarkWorld
So here's what that will look like ...
const someProcedure = async n =>_x000D_
{_x000D_
for (let i = 0; i < n; i++) {_x000D_
const t = Math.random() * 1000_x000D_
const x = await new Promise(r => setTimeout(r, t, i))_x000D_
console.log (i, x)_x000D_
}_x000D_
return 'done'_x000D_
}_x000D_
_x000D_
someProcedure(10).then(x => console.log(x)) // => Promise_x000D_
// 0 0_x000D_
// 1 1_x000D_
// 2 2_x000D_
// 3 3_x000D_
// 4 4_x000D_
// 5 5_x000D_
// 6 6_x000D_
// 7 7_x000D_
// 8 8_x000D_
// 9 9_x000D_
// done
_x000D_
See how we don't have to deal with that bothersome .then
call within our procedure? And async
keyword will automatically ensure that a Promise
is returned, so we can chain a .then
call on the returned value. This sets us up for great success: run the sequence of n
Promises, then do something important – like display a success/error message.
You have to set to element_blank()
in theme()
elements you need to remove
ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut))+
theme(axis.title.x=element_blank(),
axis.text.x=element_blank(),
axis.ticks.x=element_blank())
Use CAST(GETDATE() as date) that worked for me, simple.
first find your binaries file where it is saved. get the path in terminal mine is
C:\Users\LENOVO\Documents\postgresql-9.5.21-1-windows-x64-binaries (1)\pgsql\bin
then find your local user data path, it is in mostly
C:\usr\local\pgsql\data
now all we have to hit following command in the binary terminal path:
C:\Users\LENOVO\Documents\postgresql-9.5.21-1-windows-x64-binaries (1)\pgsql\bin>pg_ctl -D "C:\usr\local\pgsql\data" start
all done!
autovaccum launcher started! cheers!
Use the values
attribute to return the values as a np array and then use [0]
to get the first value:
In [4]:
df.loc[df.Letters=='C','Letters'].values[0]
Out[4]:
'C'
EDIT
I personally prefer to access the columns using subscript operators:
df.loc[df['Letters'] == 'C', 'Letters'].values[0]
This avoids issues where the column names can have spaces or dashes -
which mean that accessing using .
.
If you want to save data that is derived from a Javascript canvas.toDataURL()
function, you have to convert blanks into plusses. If you do not do that, the decoded data is corrupted:
<?php
$encodedData = str_replace(' ','+',$encodedData);
$decocedData = base64_decode($encodedData);
?>
You can use preg_replace in this case;
$res = preg_replace("/[^0-9]/", "", "Every 6 Months" );
$res return 6 in this case.
If want also to include decimal separator or thousand separator check this example:
$res = preg_replace("/[^0-9.]/", "", "$ 123.099");
$res returns "123.099" in this case
Include period as decimal separator or thousand separator: "/[^0-9.]/"
Include coma as decimal separator or thousand separator: "/[^0-9,]/"
Include period and coma as decimal separator and thousand separator: "/[^0-9,.]/"
If the database link option is not available, another route you could take is to link the tables via ODBC to something such as MS Access or Crystal reports and do the join there.
I tried all of that things and it doesn't worked for me.
I Just installed SAPCrystalReport in my computer and it's working now.

I come a bit late with a more advanced version of Arun P Johny's answer. His solution doesn't handle multiple console.log()

I took it a tiny bit further and added a class to each log so you can color it. It outputs all arguments as seen in the Chrome console. You also have access to the old log via console.old()
.
Here's a minified version of the script above to paste inline, just for you:
<script>
!function(o){console.old=console.log,console.log=function(){var n,e,t="";for(e=0;e<arguments.length;e++)t+='<span class="log-'+typeof(n=arguments[e])+'">',"object"==typeof n&&"object"==typeof JSON&&"function"==typeof JSON.stringify?t+=JSON.stringify(n):t+=n,t+="</span> ";o.innerHTML+=t+"<br>",console.old.apply(void 0,arguments)}}
(document.body);
</script>
Replace document.body
in the parentheses with whatever element you wish to log into.
This is the fix that I "create" and it take out the GhostClick and implements the FastClick. Try on your own and let us know if it worked for you.

if(event.handled === false) return
event.stopPropagation();
event.preventDefault();
event.handled = true;
// Do your magic here
});
By default git push
updates all the remote branches. But you can configure git to update only the current branch to it's upstream.
git config push.default upstream
It means git will update only the current (checked out) branch when you do git push.
Other valid options are:
nothing
: Do not push anything (error out) unless a refspec is explicitly given. This is primarily meant for people who want to avoid mistakes by always being explicit.matching
: Push all branches having the same name on both ends. (default option prior to Ver 1.7.11) upstream
: Push the current branch to its upstream
branch. This mode only makes sense if you are pushing to the same repository you would normally pull from (i.e. central workflow). No need to have the same name for local and remote branch.tracking
: Deprecated, use upstream
instead.current
: Push the current branch to the remote branch of the same name on the receiving end. Works in both central and non-central workflows.simple
: [available since Ver 1.7.11] in centralized workflow, work like upstream
with an added safety to refuse to push if the upstream branch’s name is different from the local one. When pushing to a remote that is different from the remote you normally pull from, work as current
. This is the safest option and is suited for beginners. This mode has become the default in Git 2.0.I don't really know Mac or Homebrew, but I know PostgreSQL very well.
You want to figure out where the logs are from PostgreSQL trying to start and what the socket directory is for PostgreSQL. By default when you build PG, the socket directory is /tmp/. If you didn't change that when you built PG and then you started PG, you should be able to see a socket file in /tmp if you do: ls -al /tmp
The socket file starts with a ".", so you won't see it with the '-a' to ls.
If you don't see a socket there, and you don't see anything from ps awux | grep postgres, then PG is probably not running, or maybe it is and it's the OSX-installed one. What might be happening is that you might be getting a conflict on listening on port 5432 on localhost- use netstat -anp to see what, if anything, is listening on 5432. If a Mac OSX PG is already listening on that port then that might be the problem.
Hope that helps. I have heard that homebrew can make things a bit ugly and a lot of people I've talked to encourage using a VM instead.
When talking about "bad input", you should consider where the input is coming from.
Is the input entered by a user or another external system you don't control, you should expect the input to be invalid, and always validate it. It's perfectly ok to throw a checked exception in this case. Your application should 'recover' from this exception by providing an error message to the user.
If the input originates from your own system, e.g. your database, or some other parts of your application, you should be able to rely on it to be valid (it should have been validated before it got there). In this case it's perfectly ok to throw an unchecked exception like an IllegalArgumentException, which should not be caught (in general you should never catch unchecked exceptions). It is a programmer's error that the invalid value got there in the first place ;) You need to fix it.

Modify your constructor to the following so that it calls the base class constructor properly:
public class MyExceptionClass : Exception
{
public MyExceptionClass(string message, string extrainfo) : base(message)
{
//other stuff here
}
}
Note that a constructor is not something that you can call anytime within a method. That's the reason you're getting errors in your call in the constructor body.
I think there are 2 things that add confusion to this topic:
I've created 5 functions that compute auto-correlation of a 1d array, with partial v.s. non-partial distinctions. Some use formula from statistics, some use correlate in the signal processing sense, which can also be done via FFT. But all results are auto-correlations in the statistics definition, so they illustrate how they are linked to each other. Code below:
import numpy
import matplotlib.pyplot as plt
def autocorr1(x,lags):
'''numpy.corrcoef, partial'''
corr=[1. if l==0 else numpy.corrcoef(x[l:],x[:-l])[0][1] for l in lags]

mean=numpy.mean(x)
var=numpy.var(x)
xp=x-mean
corr=[1. if l==0 else numpy.sum(xp[l:]*xp[:-l])/len(x)/var for l in lags]
return numpy.array(corr)
def autocorr3(x,lags):

Here is the output figure:
We don't see all 5 lines because 3 of them overlap (at the purple). The overlaps are all non-partial auto-correlations. This is because computations from the signal processing methods (np.correlate
, FFT) don't compute a different mean/std for each overlap.
Also note that the fft, no padding, non-partial
(red line) result is different, because it didn't pad the timeseries with 0s before doing FFT, so it's circular FFT. I can't explain in detail why, that's what I learned from elsewhere.
If you're using RStudio, please consider never using the rm(list = ls())
approach!* Instead, you should build your workflow around frequently employing the Ctrl
+Shift
+F10
shortcut to restart your R session. This is the fastest way to both nuke the current set of user-defined variables AND to clear loaded packages, devices, etc. The reproducibility of your work will increase markedly by adopting this habit.
See this excellent thread on Rstudio community for (h/t @kierisi) for a more thorough discussion (the main gist is captured by what I've stated already).
I must admit my own first few years of R coding featured script after script starting with the rm
"trick" -- I'm writing this answer as advice to anyone else who may be starting out their R careers.
*of course there are legitimate uses for this -- much like attach
-- but beginning users will be much better served (IMO) crossing that bridge at a later date.
Based on @dzimney answer and similar to @Crisman answer (but different)
That answer is good but has indention problem (bullets appear inside of li
scope). Probably you don't want this. See simple example list below (this is a default HTML list):
Lorem ipsum dolor sit amet, ei cum offendit partiendo iudicabit. At mei quaestio honestatis, duo dicit affert persecuti ei. Etiam nusquam cu his, nec alterum posidonium philosophia te. Nec an purto iudicabit, no vix quod clita expetendis.
Quem suscipiantur no eos, sed impedit explicari ea, falli inermis comprehensam est in. Vide dicunt ancillae cum te, habeo delenit deserunt mei in. Tale sint ex his, ipsum essent appellantur et cum.
But if you use the mentioned answer the list will be like below (ignoring the size of the bullets):
• Lorem ipsum dolor sit amet, ei cum offendit partiendo iudicabit. At mei quaestio honestatis, duo dicit affert persecuti ei. Etiam nusquam cu his, nec alterum posidonium philosophia te. Nec an purto iudicabit, no vix quod clita expetendis.
• Quem suscipiantur no eos, sed impedit explicari ea, falli inermis comprehensam est in. Vide dicunt ancillae cum te, habeo delenit deserunt mei in. Tale sint ex his, ipsum essent appellantur et cum.
So I recommend this approach that resolves the issue:
li {_x000D_
list-style-type: none;_x000D_
position: relative; /* It's needed for setting position to absolute in the next rule. */_x000D_
}_x000D_

font-size: 1.1em; /* Adjust this value so that it appears what size you want. */_x000D_
}
_x000D_

My hack during development is to change my Deployment manifest to add the latest tag and always pull like so
image: etoews/my-image:latest
imagePullPolicy: Always
Then I delete the pod manually
kubectl delete pod my-app-3498980157-2zxhd
Because it's a Deployment, Kubernetes will automatically recreate the pod and pull the latest image.
Winston is a pretty good logging library. You can write logs out to a file using it.
Code would look something like:
var winston = require('winston');
var logger = new (winston.Logger)({
transports: [
new (winston.transports.Console)({ json: false, timestamp: true }),
new winston.transports.File({ filename: __dirname + '/debug.log', json: false })
],
exceptionHandlers: [
new (winston.transports.Console)({ json: false, timestamp: true }),
new winston.transports.File({ filename: __dirname + '/exceptions.log', json: false })
],
exitOnError: false
});
module.exports = logger;
You can then use this like:
var logger = require('./log');
logger.info('log to file');
To get the location of the pg_hba.conf file, you can also query the database like
SHOW hba_file;
You should get something like
hba_file
---------------------------------
/var/lib/pgsql/data/pg_hba.conf
(1 row)
You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:
/**
* Used to stitch together functional operators into a chain.
* @method pipe
* @return {Observable} the Observable result of all of the operators having
* been called in the order they were passed in.
*
* @example
*
* import { map, filter, scan } from 'rxjs/operators';
*
* Rx.Observable.interval(1000)
* .pipe(
* filter(x => x % 2 === 0),
* map(x => x + x),
* scan((acc, x) => acc + x)
* )
* .subscribe(x => console.log(x))
*/
Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan()
, but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe()
to make a chain of those operators (see example above).
Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do()
. You can think of it as if observable was an array over time, then tap()
would be an equivalent to Array.forEach()
.
An easy way to achieve this would be:
1.Make a custom background resource (like a rectangle shape) with rounded corners.
2.set this custom background using the command -
cardView = view.findViewById(R.id.card_view2);
cardView.setBackgroundResource(R.drawable.card_view_bg);
this worked for me.
The XML
layout I made with top left and bottom right radius.
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/white" />
<corners android:topLeftRadius="18dp" android:bottomRightRadius="18dp" />
</shape>
In your case, you need to change only topLeftRadius as well as topRightRadius.
If you have a layout that overlaps with the corners of the card view and has a different color maybe, then you might need a different background resource file for the layout and in the xml set this background resource to your layout.
I tried and tested the above method. Hope this helps you.
WARNING! THIS WILL DELETE THE ENTIRE GIT HISTORY FOR YOUR SUBMODULE. ONLY DO THIS IF YOU CREATED THE SUBMODULE BY ACCIDENT. CERTAINLY NOT WHAT YOU WANT TO DO IN MOST CASES.
In my situation, there was a sub-directory which had a .git
directory.
What I do is simply remove that .git
directory from my sub-directory.
This worked for me:
var start = new Date("2020-10-15T00:00:00.000+0000");
//or
start = new date("2020-10-15T00:00:00.000Z");
collection.find({
start_date:{
$gte: start
}
})...etc

For what it's worth, this is how I managed to achieve such behavior for a general element which can be inside a DIV with scrolling (without knowing the container)
It creates a fake input of the height of the target element, and then puts a focus to it, and the browser will take care about the rest no matter how deep within the scrollable hierarchy you are. Works like a charm.
var $scrollTo = $('#someId'),
inputElem = $('<input type="text"></input>');
$scrollTo.prepend(inputElem);
inputElem.css({
position: 'absolute',
width: '1px',
height: $scrollTo.height()
});
inputElem.focus();
inputElem.remove();
The encodings are spelled out in the buffer documentation.
Character Encodings
utf8
: Multi-byte encoded Unicode characters. Many web pages and other document formats use UTF-8. This is the default character encoding.utf16le
: Multi-byte encoded Unicode characters. Unlikeutf8
, each character in the string will be encoded using either 2 or 4 bytes.latin1
: Latin-1 stands for ISO-8859-1. This character encoding only supports the Unicode characters fromU+0000
toU+00FF
.Binary-to-Text Encodings
base64
: Base64 encoding. When creating a Buffer from a string, this encoding will also correctly accept "URL and Filename Safe Alphabet" as specified in RFC 4648, Section 5.hex
: Encode each byte as two hexadecimal characters.Legacy Character Encodings
ascii
: For 7-bit ASCII data only. Generally, there should be no reason to use this encoding, as 'utf8' (or, if the data is known to always be ASCII-only, 'latin1') will be a better choice when encoding or decoding ASCII-only text.binary
: Alias for 'latin1'.ucs2
: Alias of 'utf16le'.
If you use a LinkedList instead , you can access the first element and the last one with just getFirst()
and getLast()
(if you want a cleaner way than size() -1 and get(0))
Declare a LinkedList
LinkedList<Object> mLinkedList = new LinkedList<>();
Then this are the methods you can use to get what you want, in this case we are talking about FIRST and LAST element of a list
/**
* Returns the first element in this list.
*
* @return the first element in this list
* @throws NoSuchElementException if this list is empty
*/
public E getFirst() {
final Node<E> f = first;
if (f == null)
throw new NoSuchElementException();
return f.item;
}
/**
* Returns the last element in this list.
*
* @return the last element in this list
* @throws NoSuchElementException if this list is empty
*/
public E getLast() {
final Node<E> l = last;
if (l == null)
throw new NoSuchElementException();
return l.item;
}
/**
* Removes and returns the first element from this list.
*
* @return the first element from this list
* @throws NoSuchElementException if this list is empty
*/
public E removeFirst() {
final Node<E> f = first;
if (f == null)
throw new NoSuchElementException();
return unlinkFirst(f);
}
/**
* Removes and returns the last element from this list.
*
* @return the last element from this list
* @throws NoSuchElementException if this list is empty
*/
public E removeLast() {
final Node<E> l = last;
if (l == null)
throw new NoSuchElementException();
return unlinkLast(l);
}
/**
* Inserts the specified element at the beginning of this list.
*
* @param e the element to add
*/
public void addFirst(E e) {
linkFirst(e);
}
/**
* Appends the specified element to the end of this list.
*
* <p>This method is equivalent to {@link #add}.
*
* @param e the element to add
*/
public void addLast(E e) {
linkLast(e);
}
So , then you can use
mLinkedList.getLast();
to get the last element of the list.
An easy way without using collections
public void findHighestNoInArray() {
int[] a = {1,2,6,8,9};
int large = a[0];
for(int num : a) {
if(large < num) {
large = num;
}
}
System.out.println("Large number is "+large+"");
}
I find the most simple is
shell "explorer.exe URL"
This also works to open local folders.
df -g .
Option g for Size in GBs Block and . for current working directory.
I mostly use following code to scroll down
$('html, body').animate({ scrollTop: $(SELECTOR).offset().top - 50 }, 'slow');
When you pass a pointer by a non-const
reference, you are telling the compiler that you are going to modify that pointer's value. Your code does not do that, but the compiler thinks that it does, or plans to do it in the future.
To fix this error, either declare x
constant
// This tells the compiler that you are not planning to modify the pointer
// passed by reference
void test(float * const &x){
*x = 1000;
}
or make a variable to which you assign a pointer to nKByte
before calling test
:
float nKByte = 100.0;
// If "test()" decides to modify `x`, the modification will be reflected in nKBytePtr
float *nKBytePtr = &nKByte;
test(nKBytePtr);
This question has mentioned for the OSX, but it happened to me in my linux OS.
I tried using nvm alias default <version>
but for each new terminal session the used node version was forgotten.
so, here is the solution that i figured out.
make sure to set a default alias for node version,put the following code in .bashrc, and source .bashrc
.
export NVM_DIR="/home/bonnie/.nvm"
## If the file exists and is not empty
if [ -s "$NVM_DIR/nvm.sh" ]; then
## Source it
source "$NVM_DIR/nvm.sh"
fi
NODE_DEFAULT_VERSION=$(<"$NVM_DIR/alias/default")
export PATH="$NVM_DIR/versions/node/$NODE_DEFAULT_VERSION/bin":$PATH
Ignore me. I'm sorry everyone. I'd mistyped the url of the script. Thanks to Simon Ainley for the prod in the right direction.
Sorry again. Thanks.
I just encountered a case of needing to revert just one file to previous revision, right after I had done commit and push. Shorthand syntax for specifying these revisions isn't covered by the other answers, so here's command to do that
hg revert path/to/file -r-2
That -2
will revert to the version before last commit, using -1
would just revert current uncommitted changes.
Among many others already covered in the many answers, I would highlight that SOAP enables to define a contract, the WSDL, which define the operations supported, complex types, etc. SOAP is oriented to operations, but REST is oriented at resources. Personally I would select SOAP for complex interfaces between internal enterprise applications, and REST for public, simpler, stateless interfaces with the outside world.
You have to patch catalina.jar
, as this is version number the WTP adapter looks at. It's a quite useless check, and the adapter should allow you to start the server anyway, but nobody has though of that yet.
For years and with every version of Tomcat this is always a problem.
To patch you can do the following:
cd [tomcat or tomee home]/lib
mkdir catalina
cd catalina/
unzip ../catalina.jar
vim org/apache/catalina/util/ServerInfo.properties
Make sure it looks like the following (the version numbers all need to start with 8.0):
server.info=Apache Tomcat/8.0.0
server.number=8.0.0
server.built=May 11 2016 21:49:07 UTC
Then:
jar uf ../catalina.jar org/apache/catalina/util/ServerInfo.properties
cd ..
rm -rf catalina
The Abstract Factory pattern is used in various places.
E.g., DatagramSocketImplFactory
, PreferencesFactory
. There are many more---search the Javadoc for interfaces which have the word "Factory" in their name.
Also there are quite a few instances of the Factory pattern, too.
Sure, it's how most compilers got started. GCC is probably the most popular (comes with most flavors of *nix). Syntax is just gcc my_source_code.cpp
, or gcc -o my_executable.exe my_source_code.cpp
. It gets more complicated, of course, when you have multiple source files (as in implementation; anything #include
d works automatically as long as GCC can find it).
MinGW appears to be a version of GCC for Windows, if that's what you're using. I haven't tried it though.
Pretty sure most IDEs also include a command line interface. I know Visual Studio does, though I have never used it.
Alternatively,
1) Without touching System.Reflection
namespace,
GETNAME(new { myInput });
public static string GETNAME<T>(T myInput) where T : class
{
if (myInput == null)
return string.Empty;
return myInput.ToString().TrimStart('{').TrimEnd('}').Split('=')[0].Trim();
}
2) The below one can be faster though (from my tests)
GETNAME(new { variable });
public static string GETNAME<T>(T myInput) where T : class
{
if (myInput == null)
return string.Empty;
return typeof(T).GetProperties()[0].Name;
}
You can also extend this for properties of objects (may be with extension methods):
new { myClass.MyProperty1 }.GETNAME();
You can cache property values to improve performance further as property names don't change during runtime.
The Expression approach is going to be slower for my taste. To get parameter name and value together in one go see this answer of mine
This is not a particularly good answer as it explains how to run your java code n VS Code and not necessarily a Maven
project, but it worked for me because I could not get around to doing the manual configuration myself. I decided to use this method instead since it is easier and faster.
Install VSCode (and for windows, set your environment variables), then install vscode:extension/vscjava.vscode-java-pack
as detailed above, and then install the code runner extension pack, which basically sets up the whole process (in the background) as explained in the accepted answer above and then provides a play button to run your java code when you're ready.
This was all explained in this video.
Again, this is not the best solution, but if you want to cut to the chase, you may find this answer useful.
text-shadow: -1px 0 black, 0 1px black, 1px 0 black, 0 -1px black;
You can try this:
[System.IO.FileInfo]$path = "D:\Server\User\CUST\MEA\Data\In\Files\CORRECTED\CUST_MEAFile.csv"
# Returns name and extension
$path.Name
# Returns just name
$path.BaseName
First up, this has got nothing to do with String
, it is about arrays.. and that too specifically about declarative initialization of arrays.
As discussed by everyone in almost every answer here, you can, while declaring a variable, use:
String names[] = {"x","y","z"};
However, post declaration, if you want to assign an instance of an Array:
names = new String[] {"a","b","c"};
AFAIK, the declaration syntax is just a syntactic sugar and it is not applicable anymore when assigning values to variables because when values are assigned you need to create an instance properly.
However, if you ask us why it is so? Well... good luck getting an answer to that. Unless someone from the Java committee answers that or there is explicit documentation citing the said syntactic sugar.
Note: do not mix GitLab SSL settings and GitLab SSH keys.
If what you have configured in your GitLab profile is an SSH public key, then your HTTPS URL would not use it.
Regarding your HTTPS credentials, double-check:
git config credential.helper
.I was in a weird situation in VS2019 where choosing View -> Report Data did nothing, and pressing Ctrl-Alt-D did nothing. The Report Data window had just strangely appeared on the left for no reason, when it was supposed to be on the right, and so I had moved it back to the right and then made it auto-hide. Not long after that it disappeared and would refuse to reappear. Possibly it was off-screen but hard to say.
To fix, I had to resort to using Window -> Reset Window Layout which restored its position and I was able to use it again.
To determine if there are any results you can do any of the following:
if ($mentor->first()) { }
if (!$mentor->isEmpty()) { }
if ($mentor->count()) { }
if (count($mentor)) { }
if ($mentor->isNotEmpty()) { }
Notes / References
->first()
https://laravel.com/api/5.7/Illuminate/Database/Eloquent/Collection.html#method_first
isEmpty()
https://laravel.com/api/5.7/Illuminate/Database/Eloquent/Collection.html#method_isEmpty
->count()
https://laravel.com/api/5.7/Illuminate/Database/Eloquent/Collection.html#method_count
count($mentors)
works because the Collection implements Countable and an internal count() method:
https://laravel.com/api/5.7/Illuminate/Database/Eloquent/Collection.html#method_count
isNotEmpty()
https://laravel.com/docs/5.7/collections#method-isnotempty
So what you can do is :
if (!$mentors->intern->employee->isEmpty()) { }
Following short code can help:
df3 = df3.rename(columns={c: c.replace(' ', '') for c in df3.columns})
Remove spaces from columns.
The statement:
strcpy(ptr2, ptr1);
is equivalent to (other than the fact this changes the pointers):
while(*ptr2++ = *ptr1++);
Whereas:
ptr2 = strdup(ptr1);
is equivalent to:
ptr2 = malloc(strlen(ptr1) + 1);
if (ptr2 != NULL) strcpy(ptr2, ptr1);
So, if you want the string which you have copied to be used in another function (as it is created in heap section), you can use strdup
, else strcpy
is enough,
Here's a custom theme to make the ggplot2 background white and a bunch of other changes that's good for publications and posters. Just tack on +mytheme. If you want to add or change options by +theme after +mytheme, it will just replace those options from +mytheme.
library(ggplot2)
library(cowplot)
theme_set(theme_cowplot())
mytheme = list(
theme_classic()+
theme(panel.background = element_blank(),strip.background = element_rect(colour=NA, fill=NA),panel.border = element_rect(fill = NA, color = "black"),
legend.title = element_blank(),legend.position="bottom", strip.text = element_text(face="bold", size=9),
axis.text=element_text(face="bold"),axis.title = element_text(face="bold"),plot.title = element_text(face = "bold", hjust = 0.5,size=13))
)
ggplot(data=data.frame(a=c(1,2,3), b=c(2,3,4)), aes(x=a, y=b)) + mytheme + geom_line()
To get the current path from within the JSP file you can simply do one of the following:
<%= request.getContextPath() %>
<%= request.getRequestURI() %>
<%= request.getRequestURL() %>
Typically, iterators are used to access elements of a container in linear fashion; however, with "random access iterators", it is possible to access any element in the same fashion as operator[]
.
To access arbitrary elements in a vector vec
, you can use the following:
vec.begin() // 1st
vec.begin()+1 // 2nd
// ...
vec.begin()+(i-1) // ith
// ...
vec.begin()+(vec.size()-1) // last
The following is an example of a typical access pattern (earlier versions of C++):
int sum = 0;
using Iter = std::vector<int>::const_iterator;
for (Iter it = vec.begin(); it!=vec.end(); ++it) {
sum += *it;
}
The advantage of using iterator is that you can apply the same pattern with other containers:
sum = 0;
for (Iter it = lst.begin(); it!=lst.end(); ++it) {
sum += *it;
}
For this reason, it is really easy to create template code that will work the same regardless of the container type. Another advantage of iterators is that it doesn't assume the data is resident in memory; for example, one could create a forward iterator that can read data from an input stream, or that simply generates data on the fly (e.g. a range or random number generator).
Another option using std::for_each
and lambdas:
sum = 0;
std::for_each(vec.begin(), vec.end(), [&sum](int i) { sum += i; });
Since C++11 you can use auto
to avoid specifying a very long, complicated type name of the iterator as seen before (or even more complex):
sum = 0;
for (auto it = vec.begin(); it!=vec.end(); ++it) {
sum += *it;
}
And, in addition, there is a simpler for-each variant:
sum = 0;
for (auto value : vec) {
sum += value;
}
And finally there is also std::accumulate
where you have to be careful whether you are adding integer or floating point numbers.

The basic questions that differentiate implementations of "CopyStream" are:
The answers to these questions result in vastly different implementations of CopyStream and are dependent on what kind of streams you have and what you are trying to optimize. The "best" implementation would even need to know what specific hardware the streams were reading and writing to.
To declare different layouts and bitmaps you'd like to use for the different screens, you must place these alternative resources in separate directories/folders.
This means that if you generate a 200x200
image for xhdpi
devices, you should generate the same resource in 150x150
for hdpi
, 100x100
for mdpi
, and 75x75
for ldpi
devices.
Then, place the files in the appropriate drawable resource directory:
MyProject/
res/
drawable-xhdpi/
awesomeimage.png
drawable-hdpi/
awesomeimage.png
drawable-mdpi/
awesomeimage.png
drawable-ldpi/
awesomeimage.png
Any time you reference @drawable/awesomeimage
, the system selects the appropriate bitmap based on the screen's density.
Starting from version 6 powershell supports the UTF8NoBOM
encoding both for set-content and out-file and even uses this as default encoding.
So in the above example it should simply be like this:
$MyFile | Out-File -Encoding UTF8NoBOM $MyPath
From the python command prompt:
import scipy
print scipy.__version__
In python 3 you'll need to change it to:
print (scipy.__version__)
While not exactly renaming, dplyr::select_all()

1 5.1 3.5 1.4 0.2 setosa
2 4.9 3.0 1.4 0.2 setosa

}
}
And then update the package.json
file to include this postinstall
:
"scripts": {
"postinstall": "typings install"
},
Now run npm install
Also now you should ignore typings
folder in your tsconfig.json
file as well:
"exclude": [
"node_modules",
"typings/main",
"typings/main.d.ts"
]
Update
Now AngularJS 2.0 is using core-js
instead of es6-shim
. Follow its quick start typings.json file for more info.
Short answer: There's no way to do it using CSS only.
Long(er) answer: Why? Because when you do position: absolute;
, that takes your element out of the document's regular flow, so there's no way for the text to have any positional-relationship with it, unfortunately.
One of the possible alternatives is to float: right;
your div
, but if that doesn't achieve what you want, you'll have to use JavaScript/jQuery, or just come up with a better layout.
I want to give my resolution, it work when i replace the line [session = tf.Session()]
with [sess = tf.InteractiveSession()]
. Hope this will be useful to others.
For Ubuntu, you can try:
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
For Cent OS/RHEL try :
sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686
Then, re-install the Android Studio and get success.
#include <QTextStream>
...
qDebug()<<"Bla bla bla";
To understand why, you need to know that the CPU represents signed numbers using the two's complement (maybe not all, but many).
byte n = 1; //0000 0001 = 1
n = ~n + 1; //1111 1110 + 0000 0001 = 1111 1111 = -1
And also, that the type int and unsigned int can be of different sized depending on your CPU. When doing specific stuff like this:
#include <stdint.h>
int8_t ibyte;
uint8_t ubyte;
int16_t iword;
//......
inspired from https://stackoverflow.com/a/10892768/2087666 but I use the selector instead of a class and prefer if over switch:
function clearAllInputs(selector) {
$(selector).find(':input').each(function() {
if(this.type == 'submit'){
//do nothing
}
else if(this.type == 'checkbox' || this.type == 'radio') {
this.checked = false;
}
else if(this.type == 'file'){
var control = $(this);
control.replaceWith( control = control.clone( true ) );
}else{
$(this).val('');
}
});
}
this should take care of almost all input inside any selector.
From Java 8 onward you can try the following:
import java.time.*;
import java.time.temporal.ChronoUnit;
Instant start_time = Instant.now();
// Your code
Instant stop_time = Instant.now();
System.out.println(Duration.between(start_time, stop_time).toMillis());
//or
System.out.println(ChronoUnit.MILLIS.between(start_time, stop_time));
Just want to add Matas' answer. Maybe it's obvious, but I've searched for a long time to figure out that the variable is accessible only inside the BEGIN-END construction, so if you need to use it in some code later, you need to put this code inside the BEGIN-END block.
Note that these blocks can be nested:
DECLARE x NUMBER;
BEGIN
SELECT PK INTO x FROM table1 WHERE col1 = 'test';
DECLARE y NUMBER;
BEGIN
SELECT PK INTO y FROM table2 WHERE col2 = x;
INSERT INTO table2 (col1, col2)
SELECT y,'text'
FROM dual
WHERE exists(SELECT * FROM table2);
COMMIT;
END;
END;
Here is some text from MSDN about unmanaged code.
Some library code needs to call into unmanaged code (for example, native code APIs, such as Win32). Because this means going outside the security perimeter for managed code, due caution is required.
Here is some other complimentary explication about Managed code:
For your problem:
I think it's because NUnit execute your code for UnitTesting and might have some part of it that is unmanaged. But I am not sure about it, so do not take this for gold. I am sure someone will be able to give you more information about it. Hope it helps!
It can be resolved as follows:
Go to Project properties.
Then 'Java Compiler' -> Check the box ('Enable project specific settings')
Change the compiler compliance level to '5.0' & click ok
Select the checkbox for "Use default compliance settings"
why not printf '%02d' $num
? See help printf
for this internal bash command.
You can use the JSON.parse()
for that.
Example:
var myObj = JSON.parse('{"p": 5}');
console.log(myObj);
The ArrayList uses the equals method implemented in the class (your case Thing class) to do the equals comparison.
The simplest way is:
const { exec } = require("child_process")
exec('yourApp').unref()
unref is necessary to end your process without waiting for "yourApp"
Here are the exec docs
What about this solution?
#ifndef VERSION_H
#define VERSION_H
static const char SVER[] = "14.2.1";
static const char AVER[] = "1.1.0.0";
#else
extern static const char SVER[];
extern static const char AVER[];
#endif /*VERSION_H */
The only draw back I see is that the include guard doesn't save you if you include it twice in the same file.
From the docs:
str.split([sep[, maxsplit]])
Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most
maxsplit+1
elements).
s.split('mango', 1)[1]
try this.. I had it too but now it solved in XP..

JSF is an advanced framework wherein its very easy to implement Model-View-Controller (MVC) based architecture for projects. Main advantage of JSF over JSP is the easy dynamic rendering of the components on the browser based upon conditions and easy integration of ajax events.
The front end of the JSF application i.e. xhtml files are the ones which are shown to the user via browser. These xhtml files internally invoke managed beans e.g. controllers wherein actual application logic is written.
The controllers internally invoke various services which communicate with database (using Hibernate or JPA API). This is how the flow happens in short.
JSF is also used in combination with RichFaces which is a framework for giving rich look and feel to your web application.
JSF + RichFaces + Hibernate/JPA is a good technology to learn for sure !
I use exactly the same sass mixin placeholder as NoDirection wrote. I find it in sass mixins collection here and I'm very satisfied with it. There's a text that explains a mixins option more.
SOAP - "Simple Object Access Protocol"
SOAP is a method of transferring messages, or small amounts of information, over the Internet. SOAP messages are formatted in XML and are typically sent using HTTP (hypertext transfer protocol).
Rest - Representational state transfer
Rest is a simple way of sending and receiving data between client and server and it doesn't have very many standards defined. You can send and receive data as JSON, XML or even plain text. It's light weighted compared to SOAP.
You can assign structs in C. a = b;
is valid syntax.
You simply left off part of the type -- the struct tag -- in your line that doesn't work.
To remove a timezone (tzinfo) from a datetime object:
# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)
If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.
# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)
Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime
object to insert into the database. The solution is to convert your datetime.datetime
object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime
objects where one is timezone aware and another is timezone naive.
##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
arrowDt = arrowObj.to("utc").datetime
# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)
# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()
# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3
# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True
Maybe the example with an clock could help you understand the modulo.
A familiar use of modular arithmetic is its use in the 12-hour clock, in which the day is divided into two 12 hour periods.
Lets say we have currently this time: 15:00
But you could also say it is 3 pm
This is exactly what modulo does:
15 / 12 = 1, remainder 3
You find this example better explained on wikipedia: Wikipedia Modulo Article
The optimized approach is to cache the length of array and using the single variable pattern, initializing all variables with a single var
keyword.
var i, max, myStringArray = ["Hello", "World"];
for (i = 0, max = myStringArray.length; i < max; i++) {
alert(myStringArray[i]);
// Do something
}
If the order of iteration does not matter then you should try reversed loop. It is the fastest as it reduces overhead condition testing and decrement is in one statement:
var i,myStringArray = ["item1","item2"];
for (i = myStringArray.length; i--) {
alert(myStringArray[i]);
}
Or better and cleaner to use a while loop:
var myStringArray = ["item1","item2"],i = myStringArray.length;
while(i--) {
// Do something with fruits[i]
}
It must relate to the renaming and deprecation of cross_validation
sub-module to model_selection
. Try substituting cross_validation
to model_selection
It's a linker error. ld
is the linker, so if you get an error message ending with "ld returned 1 exit status", that tells you that it's a linker error.
The error message tells you that none of the object files you're linking against contains a definition for avergecolumns
. The reason for that is that the function you've defined is called averagecolumns
(in other words: you misspelled the function name when calling the function (and presumably in the header file as well - otherwise you'd have gotten a different error at compile time)).
I found the answer to the second part of my questions. Yes, a class can implement an interface that is in a different class as long that the interface is declared as public.
You need to git add my_project
to stage your new folder. Then git add my_project/*
to stage its contents. Then commit what you've staged using git commit
and finally push your changes back to the source using git push origin master
(I'm assuming you wish to push to the master branch).
If you have a list of lists, you only needed to use ...
import numpy as np
...
npa = np.asarray(someListOfLists, dtype=np.float32)
per this LINK in the scipy / numpy documentation. You just needed to define dtype inside the call to asarray.
There are many examples and also of different types for logging. Take a look at the java.util.logging package.
Example code:
import java.util.logging.Logger;
public class Main {
private static Logger LOGGER = Logger.getLogger("InfoLogging");
public static void main(String[] args) {
LOGGER.info("Logging an INFO-level message");
}
}
Without hard-coding the class name:
import java.util.logging.Logger;
public class Main {
private static final Logger LOGGER = Logger.getLogger(
Thread.currentThread().getStackTrace()[0].getClassName() );
public static void main(String[] args) {
LOGGER.info("Logging an INFO-level message");
}
}
1NF is the most basic of normal forms - each cell in a table must contain only one piece of information, and there can be no duplicate rows.
2NF and 3NF are all about being dependent on the primary key. Recall that a primary key can be made up of multiple columns. As Chris said in his response:
The data depends on the key [1NF], the whole key [2NF] and nothing but the key [3NF] (so help me Codd).
Say you have a table containing courses that are taken in a certain semester, and you have the following data:
|-----Primary Key----| uh oh |
V
CourseID | SemesterID | #Places | Course Name |
------------------------------------------------|
IT101 | 2009-1 | 100 | Programming |
IT101 | 2009-2 | 100 | Programming |
IT102 | 2009-1 | 200 | Databases |
IT102 | 2010-1 | 150 | Databases |
IT103 | 2009-2 | 120 | Web Design |
This is not in 2NF, because the fourth column does not rely upon the entire key - but only a part of it. The course name is dependent on the Course's ID, but has nothing to do with which semester it's taken in. Thus, as you can see, we have duplicate information - several rows telling us that IT101 is programming, and IT102 is Databases. So we fix that by moving the course name into another table, where CourseID is the ENTIRE key.
Primary Key |
CourseID | Course Name |
---------------------------|
IT101 | Programming |
IT102 | Databases |
IT103 | Web Design |
No redundancy!
Okay, so let's say we also add the name of the teacher of the course, and some details about them, into the RDBMS:
|-----Primary Key----| uh oh |
V
Course | Semester | #Places | TeacherID | TeacherName |
---------------------------------------------------------------|
IT101 | 2009-1 | 100 | 332 | Mr Jones |
IT101 | 2009-2 | 100 | 332 | Mr Jones |
IT102 | 2009-1 | 200 | 495 | Mr Bentley |
IT102 | 2010-1 | 150 | 332 | Mr Jones |
IT103 | 2009-2 | 120 | 242 | Mrs Smith |
Now hopefully it should be obvious that TeacherName is dependent on TeacherID - so this is not in 3NF. To fix this, we do much the same as we did in 2NF - take the TeacherName field out of this table, and put it in its own, which has TeacherID as the key.
Primary Key |
TeacherID | TeacherName |
---------------------------|
332 | Mr Jones |
495 | Mr Bentley |
242 | Mrs Smith |
No redundancy!!
One important thing to remember is that if something is not in 1NF, it is not in 2NF or 3NF either. So each additional Normal Form requires everything that the lower normal forms had, plus some extra conditions, which must all be fulfilled.
struct A {};
struct B : A {};
struct C {};
int main()
{
A* a = new A;
int i = 10;
a = (A*) (&i); // NO ERROR! FAIL!
//a = static_cast<A*>(&i); ERROR! SMART!
A* b = new B;
B* b2 = static_cast<B*>(b); // NO ERROR! SMART!
C* c = (C*)(b); // NO ERROR! FAIL!
//C* c = static_cast<C*>(b); ERROR! SMART!
}
You can also try TFS CLI for Node.js which is a cross-platform CLI for Microsoft Team Foundation Server and Visual Studio Team Services.
I want to point to the way Wordpress handles this:
define( 'ABSPATH', dirname( __FILE__ ) . '/' );
As Wordpress is very heavy used all over the web and also works fine locally I have much trust in this method. You can find this definition on the bottom of your wordpress wp-config.php
file

TEXT is a data-type for text based input. On the other hand, you have BLOB and CLOB which are more suitable for data storage (images, etc) due to their larger capacity limits (4GB for example).
As for the difference between BLOB and CLOB, I believe CLOB has character encoding associated with it, which implies it can be suited well for very large amounts of text.
BLOB and CLOB data can take a long time to retrieve, relative to how quick data from a TEXT field can be retrieved. So, use only what you need.
try this:
head -1 /etc/*release | awk '{print $1}'
Look at the filter
function.
If you just need a 1-pole low-pass filter, it's
xfilt = filter(a, [1 a-1], x);
where a = T/τ, T = the time between samples, and τ (tau) is the filter time constant.
Here's the corresponding high-pass filter:
xfilt = filter([1-a a-1],[1 a-1], x);
If you need to design a filter, and have a license for the Signal Processing Toolbox, there's a bunch of functions, look at fvtool and fdatool.
You probably are looking for AddReference dialog accessible from Project Context Menu (right click..)
From there you can reference dll's, after which you can reference namespaces that you need in your code.
I (and the rest of our team in my company) prefer to raise exceptions instead of returning error codes. Error codes have to be checked everywhere, passed around, and tend to make the code unreadable when the amount of code becomes bigger.
The error class would then define the message.
PS: and actually also care for internationalization !
PPS: you could also redefine the raise-method and add logging, filtering etc. if required (at leastin environments, where the Exception classes and friends are extendable/changeable)

This link on MSDN also helps a lot to understand the reason why it doesn't work. $(MSBuildToolsPath) is the path to Microsoft.Build.Engine v3.5 (inserted automatically in a project file when you create in VS2008). If you try to build your project for .Net 2.0, be sure that you changed this path to $(MSBuildBinPath) which is the path to Microsoft.Build.Engine v2.0.
