Use the elevation property for shadow affect:
<YourView
...
android:elevation="3dp"/>
.hide()
stores the previous display
property just before setting it to none
, so if it wasn't the standard display
property for the element you're a bit safer, .show()
will use that stored property as what to go back to. So...it does some extra work, but unless you're doing tons of elements, the speed difference should be negligible.
In Android Marshmallow many methods are deprecated.
For example, to get color use
ContextCompat.getColor(context, R.color.color_name);
Also to get drawable use
ContextCompat.getDrawable(context, R.drawable.drawble_name);

A semaphore is a way to lock a resource so that it is guaranteed that while a piece of code is executed, only this piece of code has access to that resource. This keeps two threads from concurrently accesing a resource, which can cause problems.
UIButton extension with Swift 3+ syntax:
extension UIButton {
func setBackgroundColor(color: UIColor, forState: UIControlState) {
UIGraphicsBeginImageContext(CGSize(width: 1, height: 1))
UIGraphicsGetCurrentContext()!.setFillColor(color.cgColor)
UIGraphicsGetCurrentContext()!.fill(CGRect(x: 0, y: 0, width: 1, height: 1))
let colorImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
self.setBackgroundImage(colorImage, for: forState)
}}
Use it like:
YourButton.setBackgroundColor(color: UIColor.white, forState: .highlighted)

It seems to me you are using the wrong version...
TAP-Win32 should not be installed on the 64bit version. Download the right one and try again!
The limit for the length of a command line is not imposed by the shell, but by the operating system. This limit is usually in the range of hundred kilobytes. POSIX denotes this limit ARG_MAX
and on POSIX conformant systems you can query it with
$ getconf ARG_MAX # Get argument limit in bytes
E.g. on Cygwin this is 32000, and on the different BSDs and Linux systems I use it is anywhere from 131072 to 2621440.
If you need to process a list of files exceeding this limit, you might want to look at the xargs
utility, which calls a program repeatedly with a subset of arguments not exceeding ARG_MAX
.
To answer your specific question, yes, it is possible to attempt to run a command with too long an argument list. The shell will error with a message along "argument list too long".
Note that the input to a program (as read on stdin or any other file descriptor) is not limited (only by available program resources). So if your shell script reads a string into a variable, you are not restricted by ARG_MAX
. The restriction also does not apply to shell-builtins.

This is extemporary, but I had the same problem which I solved this way. In my case I was uploading the files via XMLHttp request, so I was able to post the FileList cloned data through formdata appending. Functionality is that you can drag and drop or select multiple files as many times as you want (selecting files again won't reset the cloned FileList), remove any file you want from the (cloned) file list, and submit via xmlhttprequest whatever was left there. This is what I did. It is my first post here so code is a little messy. Sorry. Ah, and I had to use jQuery instead of $ as it was in Joomla script.
// some global variables
var clon = {}; // will be my FileList clone
var removedkeys = 0; // removed keys counter for later processing the request
var NextId = 0; // counter to add entries to the clone and not replace existing ones
jQuery(document).ready(function(){
jQuery("#form input").change(function () {
// making the clone
var curFiles = this.files;
// temporary object clone before copying info to the clone
var temparr = jQuery.extend(true, {}, curFiles);
// delete unnecessary FileList keys that were cloned
delete temparr["length"];
delete temparr["item"];
if (Object.keys(clon).length === 0){
jQuery.extend(true, clon, temparr);
}else{
var keysArr = Object.keys(clon);
NextId = Math.max.apply(null, keysArr)+1; // FileList keys are numbers
if (NextId < curFiles.length){ // a bug I found and had to solve for not replacing my temparr keys...
NextId = curFiles.length;
}
for (var key in temparr) { // I have to rename new entries for not overwriting existing keys in clon
if (temparr.hasOwnProperty(key)) {
temparr[NextId] = temparr[key];
delete temparr[key];
// meter aca los cambios de id en los html tags con el nuevo NextId
NextId++;
}
}
jQuery.extend(true, clon, temparr); // copy new entries to clon
}
// modifying the html file list display
if (NextId === 0){
jQuery("#filelist").html("");
for(var i=0; i<curFiles.length; i++) {
var f = curFiles[i];
jQuery("#filelist").append("<p id=\"file"+i+"\" style=\'margin-bottom: 3px!important;\'>" + f.name + "<a style=\"float:right;cursor:pointer;\" onclick=\"BorrarFile("+i+")\">x</a></p>"); // the function BorrarFile will handle file deletion from the clone by file id
}
}else{
for(var i=0; i<curFiles.length; i++) {
var f = curFiles[i];
jQuery("#filelist").append("<p id=\"file"+(i+NextId-curFiles.length)+"\" style=\'margin-bottom: 3px!important;\'>" + f.name + "<a style=\"float:right;cursor:pointer;\" onclick=\"BorrarFile("+(i+NextId-curFiles.length)+")\">x</a></p>"); // yeap, i+NextId-curFiles.length actually gets it right
}
}
// update the total files count wherever you want
jQuery("#form p").text(Object.keys(clon).length + " file(s) selected");
});
});
function BorrarFile(id){ // handling file deletion from clone
jQuery("#file"+id).remove(); // remove the html filelist element
delete clon[id]; // delete the entry
removedkeys++; // add to removed keys counter
if (Object.keys(clon).length === 0){
jQuery("#form p").text(Object.keys(clon).length + " file(s) selected");
jQuery("#fileToUpload").val(""); // I had to reset the form file input for my form check function before submission. Else it would send even though my clone was empty
}else{
jQuery("#form p").text(Object.keys(clon).length + " file(s) selected");
}
}
// now my form check function
function check(){
if( document.getElementById("fileToUpload").files.length == 0 ){
alert("No file selected");
return false;
}else{
var _validFileExtensions = [".pdf", ".PDF"]; // I wanted pdf files
// retrieve input files
var arrInputs = clon;
// validating files
for (var i = 0; i < Object.keys(arrInputs).length+removedkeys; i++) {
if (typeof arrInputs[i]!="undefined"){
var oInput = arrInputs[i];
if (oInput.type == "application/pdf") {
var sFileName = oInput.name;
if (sFileName.length > 0) {
var blnValid = false;
for (var j = 0; j < _validFileExtensions.length; j++) {
var sCurExtension = _validFileExtensions[j];

return false;
}
}
}else{
alert("Sorry, " + arrInputs[0].name + " is invalid, allowed extensions are: " + _validFileExtensions.join(" or "));
return false;
}
}
}
// proceed with the data appending and submission
// here some hidden input values i had previously set. Now retrieving them for submission. My form wasn't actually even a form...
var fecha = jQuery("#fecha").val();
var vendor = jQuery("#vendor").val();
var sku = jQuery("#sku").val();
// create the formdata object
var formData = new FormData();
formData.append("fecha", fecha);
formData.append("vendor", encodeURI(vendor));
formData.append("sku", sku);
// now appending the clone file data (finally!)
var fila = clon; // i just did this because I had already written the following using the "fila" object, so I copy my clone again
// the interesting part. As entries in my clone object aren't consecutive numbers I cannot iterate normally, so I came up with the following idea
for (i = 0; i < Object.keys(fila).length+removedkeys; i++) {
if(typeof fila[i]!="undefined"){
formData.append("fileToUpload[]", fila[i]); // VERY IMPORTANT the formdata key for the files HAS to be an array. It will be later retrieved as $_FILES['fileToUpload']['temp_name'][i]
}
}
jQuery("#submitbtn").fadeOut("slow"); // remove the upload btn so it can't be used again
jQuery("#drag").html(""); // clearing the output message element
// start the request
var xhttp = new XMLHttpRequest();
xhttp.addEventListener("progress", function(e) {
var done = e.position || e.loaded, total = e.totalSize || e.total;
}, false);
if ( xhttp.upload ) {
xhttp.upload.onprogress = function(e) {
var done = e.position || e.loaded, total = e.totalSize || e.total;
var percent = done / total;
jQuery("#drag").html(Math.round(percent * 100) + "%");
};
}
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var respuesta = this.responseText;
jQuery("#drag").html(respuesta);
}
};
xhttp.open("POST", "your_upload_handler.php", true);
xhttp.send(formData);
return true;
}
};
Now the html and styles for this. I'm quite a newbie but all this actually worked for me and took me a while to figure it out.
<div id="form" class="formpos">
<!-- Select the pdf to upload:-->
<input type="file" name="fileToUpload[]" id="fileToUpload" accept="application/pdf" multiple>
<div><p id="drag">Drop your files here or click to select them</p>
</div>
<button id="submitbtn" onclick="return check()" >Upload</button>
// these inputs are passed with different names on the formdata. Be aware of that
// I was echoing this, so that's why I use the single quote for php variables
<input type="hidden" id="fecha" name="fecha_copy" value="'.$fecha.'" />
<input type="hidden" id="vendor" name="vendorname" value="'.$vendor.'" />
<input type="hidden" id="sku" name="sku" value="'.$sku.'"" />
</div>
<h1 style="width: 500px!important;margin:20px auto 0px!important;font-size:24px!important;">File list:</h1>
<div id="filelist" style="width: 500px!important;margin:10px auto 0px!important;">Nothing selected yet</div>
The styles for that. I had to mark some of them !important to override Joomla behavior.
.formpos{
width: 500px;
height: 200px;
border: 4px dashed #999;
margin: 30px auto 100px;
}
.formpos p{
text-align: center!important;
padding: 80px 30px 0px;
color: #000;
}
.formpos div{
width: 100%!important;
height: 100%!important;
text-align: center!important;
margin-bottom: 30px!important;
}
.formpos input{
position: absolute!important;
margin: 0!important;
padding: 0!important;
width: 500px!important;
height: 200px!important;
outline: none!important;
opacity: 0!important;
}
.formpos button{
margin: 0;
color: #fff;
background: #16a085;
border: none;
width: 508px;
height: 35px;
margin-left: -4px;
border-radius: 4px;
transition: all .2s ease;
outline: none;
}
.formpos button:hover{
background: #149174;
color: #0C5645;
}
.formpos button:active{
border:0;
}
I hope this helps.
It is usually not recommended to call flush explicitly unless it is necessary. Hibernate usually auto calls Flush at the end of the transaction and we should let it do it's work. Now, there are some cases where you might need to explicitly call flush where a second task depends upon the result of the first Persistence task, both being inside the same transaction.
For example, you might need to persist a new Entity and then use the Id of that Entity to do some other task inside the same transaction, on that case it's required to explicitly flush the entity first.
@Transactional
void someServiceMethod(Entity entity){
em.persist(entity);
em.flush() //need to explicitly flush in order to use id in next statement
doSomeThingElse(entity.getId());
}
Also Note that, explicitly flushing does not cause a database commit, a database commit is done only at the end of a transaction, so if any Runtime error occurs after calling flush the changes would still Rollback.
You can't do something like that: (int(sumall[0])+int(sumall[1]))
That's because sumall

In order to add the file to the email as an attachment, it will need to be stored on the server briefly. It's trivial, though, to place it in a tmp location then delete it after you're done with it.
As for emailing, Zend Mail has a very easy to use interface for dealing with email attachments. We run with the whole Zend Framework installed, but I'm pretty sure you could just install the Zend_Mail library without needing any other modules for dependencies.
With Zend_Mail, sending an email with an attachment is as simple as:
$mail = new Zend_Mail();
$mail->setSubject("My Email with Attachment");
$mail->addTo("[email protected]");
$mail->setBodyText("Look at the attachment");
$attachment = $mail->createAttachment(file_get_contents('/path/to/file'));
$mail->send();
If you're looking for a one-file-package to do the whole form/email/attachment thing, I haven't seen one. But the individual components are certainly available and easy to assemble. Trickiest thing of the whole bunch is the email attachment, which the above recommendation makes very simple.
Is there any disadvantages/consequences of pushing empty commits?
Aside from the extreme confusion someone might get as to why there's a bunch of commits with no content in them on master, not really.
You can change the commit that you pushed to remote, but the sha1 of the commit (basically it's id number) will change permanently, which alters the source tree -- You'd then have to do a git push -f
back to remote.
run this in Command Prompt windows (cmd.exe).
set PATH=C:\xampp\php;%PATH%
change it depending where you put the php 7 installation.

Since we are only looking at the distribution of a single variable ("Position") as opposed to looking at the relationship between two variables, then perhaps a histogram would be the more appropriate graph. ggplot has geom_histogram() that makes it easy:
ggplot(theTable, aes(x = Position)) + geom_histogram(stat="count")
Using geom_histogram():
I think geom_histogram() is a little quirky as it treats continuous and discrete data differently.
For continuous data, you can just use geom_histogram() with no parameters. For example, if we add in a numeric vector "Score"...
Name Position Score
1 James Goalkeeper 10
2 Frank Goalkeeper 20
3 Jean Defense 10
4 Steve Defense 10
5 John Defense 20
6 Tim Striker 50
and use geom_histogram() on the "Score" variable...
ggplot(theTable, aes(x = Score)) + geom_histogram()
For discrete data like "Position" we have to specify a calculated statistic computed by the aesthetic to give the y value for the height of the bars using stat = "count"
:
ggplot(theTable, aes(x = Position)) + geom_histogram(stat = "count")
Note: Curiously and confusingly you can also use stat = "count"
for continuous data as well and I think it provides a more aesthetically pleasing graph.
ggplot(theTable, aes(x = Score)) + geom_histogram(stat = "count")

According to the definition of getchar()
, it reads a character from the standard input. Unfortunately stdin
is mistaken for keyboard which might not be the case for getchar
. getchar
uses a buffer as stdin
and reads a single character at a time. In your case since there is no EOF
, the getchar
and putchar
are running multiple times and it looks to you as it the whole string is being printed out at a time. Make a small change and you will understand:
putchar(c);
printf("\n");
c = getchar();
Now look at the output compared to the original code.
Another example that will explain you the concept of getchar
and buffered stdin
:
void main(){
int c;
printf("Enter character");
c = getchar();
putchar();
c = getchar();
putchar();
}
Enter two characters in the first case. The second time when getchar
is running are you entering any character? NO but still putchar
works.
This ultimately means there is a buffer and when ever you are typing something and click enter this goes and settles in the buffer. getchar
uses this buffer as stdin
.
Add following at start of cell and run it:

I believe what the interviewer was trying to get at was probably the difference between interface and implementation.
The interface - not a Java interface, but "interface" in more general terms - to a code module is, basically, the contract made with client code that uses the interface.
The implementation of a code module is the internal code that makes the module work. Often you can implement a particular interface in more than one different way, and even change the implementation without client code even being aware of the change.
A Java interface should only be used as an interface in the above generic sense, to define how the class behaves for the benefit of client code using the class, without specifying any implementation. Thus, an interface includes method signatures - the names, return types, and argument lists - for methods expected to be called by client code, and in principle should have plenty of Javadoc for each method describing what that method does. The most compelling reason for using an interface is if you plan to have multiple different implementations of the interface, perhaps selecting an implementation depending on deployment configuration.
A Java abstract class, in contrast, provides a partial implementation of the class, rather than having a primary purpose of specifying an interface. It should be used when multiple classes share code, but when the subclasses are also expected to provide part of the implementation. This permits the shared code to appear in only one place - the abstract class - while making it clear that parts of the implementation are not present in the abstract class and are expected to be provided by subclasses.
This should work.

I am using Visual Studio 2017 15.4.0 version. Especially when i started use lightweight solution option, this offline thing happened to me. I tried to above solutions which are:
Then from File -> Source Control -> Advanced -> Change Source Control. I saw my files. I select them and then chose bind option. That worked for me.
I found the option in the menu, under Edit > Lines > Auto Indent. It doesn't seem to have a default keymap bound.
You could try to add a key mapping (Atom > Open Your Keymap [on Windows: File > Settings > Keybindings > "your keymap file"]) like this one:
'atom-text-editor':
'cmd-alt-l': 'editor:auto-indent'
It worked for me :)
For Windows:
'atom-text-editor':
'ctrl-alt-l': 'editor:auto-indent'
This is what worked for me just now:

OK, two steps to this - first is to write a function that does the translation you want - I've put an example together based on your pseudo-code:
def label_race (row):
if row['eri_hispanic'] == 1 :
return 'Hispanic'
if row['eri_afr_amer'] + row['eri_asian'] + row['eri_hawaiian'] + row['eri_nat_amer'] + row['eri_white'] > 1 :
return 'Two Or More'
if row['eri_nat_amer'] == 1 :
return 'A/I AK Native'
if row['eri_asian'] == 1:
return 'Asian'
if row['eri_afr_amer'] == 1:
return 'Black/AA'
if row['eri_hawaiian'] == 1:
return 'Haw/Pac Isl.'
if row['eri_white'] == 1:
return 'White'
return 'Other'
You may want to go over this, but it seems to do the trick - notice that the parameter going into the function is considered to be a Series object labelled "row".
Next, use the apply function in pandas to apply the function - e.g.
df.apply (lambda row: label_race(row), axis=1)
Note the axis=1 specifier, that means that the application is done at a row, rather than a column level. The results are here:
0 White
1 Hispanic
2 White
3 White
4 Other
5 White
6 Two Or More
7 White
8 Haw/Pac Isl.
9 White
If you're happy with those results, then run it again, saving the results into a new column in your original dataframe.
df['race_label'] = df.apply (lambda row: label_race(row), axis=1)
The resultant dataframe looks like this (scroll to the right to see the new column):
lname fname rno_cd eri_afr_amer eri_asian eri_hawaiian eri_hispanic eri_nat_amer eri_white rno_defined race_label
0 MOST JEFF E 0 0 0 0 0 1 White White

6 DENIRO ROBERT E 0 1 0 0 0 1 White Two Or More
7 PACINO AL E 0 0 0 0 0 1 White White

If you need to see the output of the execute, use CALL
together with or instead of START
.
Example:
CALL "C:\Program Files\Certain Directory\file.exe" -param
PAUSE
This will run the file.exe and print back whatever it outputs, in the same command window. Remember the PAUSE
after the call or else the window may close instantly.
You can't get a path to file from WhatsApp. They don't expose it now. The only thing you can get is InputStream
:
InputStream is = getContentResolver().openInputStream(Uri.parse("content://com.whatsapp.provider.media/item/16695"));
Using is
you can show a picture from WhatsApp in your app.
You could use DOM4j doing that.

You need to delimit each parameter name with a ":" at the very least. Technically the name is optional, but it is recommended for readability. So you could write:
- (NSMutableArray*)getBusStops:(NSString*)busStop :(NSSTimeInterval*)timeInterval;
or what you suggested:
- (NSMutableArray*)getBusStops:(NSString*)busStop forTime:(NSSTimeInterval*)timeInterval;
In the class onCreateView, I put this:
Dialog d = getDialog();
d.setTitle(Html.fromHtml("<font color='#EC407A'>About</font>"));
int dividerId = d.getContext().getResources().getIdentifier("android:id/titleDivider", null, null);
View divider = d.findViewById(dividerId);
divider.setBackgroundColor(getResources().getColor(R.color.colorPrimary));
colorPrimary links to our colors.xml file that stores all the colors. Also d.setTitle
provides a hacky way to set the title colour.
This isn't exactly what you are looking for but here is how I've approached this problem in the past;
You can enter a formula like;
=COUNTIF(A1:A10,"Green")
...into a cell. This will count the Number of cells between A1 and A10 that contain the text "Green". You can then select this cell value in a VBA Macro and assign it to a variable as normal.
To simply answer your question when you do a mvn:install, maven will create a packaged artifact based on (packaging attribute in pom.xml), After you run your maven install you can find the file with .package extension

"Valid Signing identity not found" This is because you don't have the private key for distribution certificate.
If the distribution certificate was created originally on a different Mac you may need to import this private key from that Mac. This private key is not available to download from your provisioning portal.
When you import the correct private key to your mac , XCode's organizer will recognize your already downloaded distribution profile as a "Valid profile"
However if you do not have access to the original Mac which created those profiles, the only option you have is revoking profiles.

I had the same problem and I fixed by setting transparent png image as background for the parent tag.
This is the 1px x 1px PNG Image that I have created with 60% Opacity of black background !
Two things:
Use:
DECLARE @temp VARCHAR(10)
SET @temp = 'm'
IF @temp = 'm'
SELECT 'yes'
ELSE
SELECT 'no'
VARCHAR(10)
means the VARCHAR will accommodate up to 10 characters. More examples of the behavior -
DECLARE @temp VARCHAR
SET @temp = 'm'
IF @temp = 'm'
SELECT 'yes'
ELSE
SELECT 'no'
...will return "yes"
DECLARE @temp VARCHAR
SET @temp = 'mtest'
IF @temp = 'm'
SELECT 'yes'
ELSE
SELECT 'no'
...will return "no".
empty() used to work for this, but the behavior of empty() has changed several times. As always, the php docs are always the best source for exact behavior and the comments on those pages usually provide a good history of the changes over time. If you want to check for a lack of object properties, a very defensive method at the moment is:
if (is_object($theObject) && (count(get_object_vars($theObject)) > 0)) {
I think it is worth pointing out that by the rules of the Java language the Java compiler inserts the equivalent of "this." when it notices that you're accessing instance methods or instance fields without an explicit instance. Of course, the compiler knows that it can only do this from within an instance method, which has a "this" variable, as static methods don't.
Which means that when you're in an instance method the following are equivalent:
instanceMethod();
this.instanceMethod();
and these are also equivalent:
... = instanceField;
... = this.instanceField;
The compiler is effectively inserting the "this." when you don't supply a specific instance.
This (pun intended) bit of "magic help" by the compiler can confuse novices: it means that instance calls and static calls sometimes appear to have the same syntax while in reality are calls of different types and underlying mechanisms.
The instance method call is sometimes referred to as a method invocation or dispatch because of the behaviors of virtual methods supporting polymorphism; dispatching behavior happens regardless of whether you wrote an explicit object instance to use or the compiler inserted a "this.".
The static method call mechanism is simpler, like a function call in a non-OOP language.
Personally, I think the error message is misleading, it could read "non-static method cannot be referenced from a static context without specifying an explicit object instance".
What the compiler is complaining about is that it cannot simply insert the standard "this." as it does within instance methods, because this code is within a static method; however, maybe the author merely forgot to supply the instance of interest for this invocation — say, an instance possibly supplied to the static method as parameter, or created within this static method.
In short, you most certainly can call instance methods from within a static method, you just need to have and specify an explicit instance object for the invocation.

As others have said, the minumum/maximum values the column can store and how much storage it takes in bytes is only defined by the type, not the length.
A lot of these answers are saying that the (11)
part only affects the display width which isn't exactly true, but mostly.
A definition of int(2)
with no zerofill specified will:
100
100
when output (not 0
or 00
)The only thing the (2)
will do is if zerofill is also specified:
1
will be shown 01
. The best way to see all the nuances is to run:
CREATE TABLE `mytable` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`int1` int(10) NOT NULL,
`int2` int(3) NOT NULL,
`zf1` int(10) ZEROFILL NOT NULL,
`zf2` int(3) ZEROFILL NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `mytable`
(`int1`, `int2`, `zf1`, `zf2`)
VALUES
(10000, 10000, 10000, 10000),
(100, 100, 100, 100);
select * from mytable;
which will output:
+----+-------+-------+------------+-------+
| id | int1 | int2 | zf1 | zf2 |

| 1 | 10000 | 10000 | 0000010000 | 10000 |

If you have access to Excel, look in the "Statistical Functions" section of the Function Reference within Help. For straight-line best-fit, you need SLOPE and INTERCEPT and the equations are right there.
Oh, hang on, they're also defined online here: http://office.microsoft.com/en-us/excel/HP052092641033.aspx for SLOPE, and there's a link to INTERCEPT. OF course, that assumes MS don't move the page, in which case try Googling for something like "SLOPE INTERCEPT EQUATION Excel site:microsoft.com" - the link given turned out third just now.
With Swift 3
extension UIImageView{
var imageWithFade:UIImage?{
get{
return self.image
}
set{
UIView.transition(with: self,
duration: 0.5, options: .transitionCrossDissolve, animations: {
self.image = newValue
}, completion: nil)
}
}
}
Usage:
myImageView.imageWithFade = myImage
Well one solution could be:
list.get(list.size()-1)
Edit: You have to convert the collection to a list before maybe like this: new ArrayList(coll)
First convert the numeric value then add the 'S'
:
select convert(varchar(10),StandardCost) +'S'
from DimProduct where ProductKey = 212
For me, running the ad-hoc network on Windows 8.1, it was two things:
Any IP will allow you to connect, but if you want internet access the static IP should match the subnet from the shared internet connection.
I'm not sure why I couldn't get a longer password to work, but it's worth a try. Maybe a more knowledgeable person could fill us in.
Yet another way to do this:
(Get-Date).AddDays(-1).Date.AddHours(22)
I think I had a better output, especially for a double datatype sorting.
Though this question has been marked answered, perhaps this will help someone else;
Arrays.sort(newTag, new Comparator<String[]>() {
@Override
public int compare(final String[] entry1, final String[] entry2) {
final Integer time1 = (int)Integer.valueOf((int) Double.parseDouble(entry1[2]));
final Integer time2 = (int)Integer.valueOf((int) Double.parseDouble(entry2[2]));
return time1.compareTo(time2);
}
});
That's what ln
is documented to do when the target already exists and is a directory. If you want /etc/nginx
to be a symlink rather than contain a symlink, you had better not create it as a directory first!
If you get this error when you are running it, then probably its because you have not included mysql-connector JAR file to your webserver's lib folder.
Now it is important to add mysql-connector-java-5.1.25-bin.jar to your classpath and also to your webserver's lib directory. Tomcat lib path is given as an example Tomcat 6.0\lib
Surely this whole question should be:
"How do I obtain the horizontal and vertical PPI (Pixels Per Inch) of the monitor?"
There are 72 points in an inch (by definition, a "point" is defined as 1/72nd of an inch, likewise a "pica" is defined as 1/72nd of a foot). With these two bits of information you can convert from px to pt and back very easily.
Base 64 for html:
file="DSC_0251.JPG"
type=$(identify -format "%m" "$file" | tr '[A-Z]' '[a-z]')
echo "data:image/$type;base64,$(base64 -w 0 "$file")"
Just before executing the query: alter session set NLS_DATE_FORMAT = "DD.MM.YYYY HH24:MI:SS"; or whichever format you are giving the information to the date function. This should fix the ORA error
Note that $(element).offset()
tells you the position of an element relative to the document. This works great in most circumstances, but in the case of position:fixed
you can get unexpected results.
If your document is longer than the viewport and you have scrolled vertically toward the bottom of the document, then your position:fixed
element's offset()
value will be greater than the expected value by the amount you have scrolled.
If you are looking for a value relative to the viewport (window), rather than the document on a position:fixed element, you can subtract the document's scrollTop()
value from the fixed element's offset().top
value. Example: $("#el").offset().top - $(document).scrollTop()
If the position:fixed
element's offset parent is the document, you want to read parseInt($.css('top'))
instead.
You have several options:
string[] items = { "Item1", "Item2", "Item3", "Item4" };
string[] items = new string[]
{
"Item1", "Item2", "Item3", "Item4"
};
string[] items = new string[10];
items[0] = "Item1";
items[1] = "Item2"; // ...
You can't expect ObjectInputStream
to automagically convert text into objects. The hexadecimal 54657374
is "Test"
as text. You must be sending it directly as bytes.
You can do it like this:
var mongoose = require('mongoose');
var _id = mongoose.mongo.BSONPure.ObjectID.fromHexString("4eb6e7e7e9b7f4194e000001");
EDIT: New standard has fromHexString rather than fromString
You can create a data.sql file in your src/main/resources folder and it will be automatically executed on startup. In this file you can add some insert statements, eg.:
INSERT INTO users (username, firstname, lastname) VALUES
('lala', 'lala', 'lala'),
('lolo', 'lolo', 'lolo');
Similarly, you can create a schema.sql file (or schema-h2.sql) as well to create your schema:
CREATE TABLE task (
id INTEGER PRIMARY KEY,
description VARCHAR(64) NOT NULL,
completed BIT NOT NULL);
Though normally you shouldn't have to do this since Spring boot already configures Hibernate to create your schema based on your entities for an in memory database. If you really want to use schema.sql you'll have to disable this feature by adding this to your application.properties:
spring.jpa.hibernate.ddl-auto=none
More information can be found at the documentation about Database initialization.
If you're using Spring boot 2, database initialization only works for embedded databases (H2, HSQLDB, ...). If you want to use it for other databases as well, you need to change the spring.datasource.initialization-mode
property:
spring.datasource.initialization-mode=always
If you're using multiple database vendors, you can name your file data-h2.sql or data-mysql.sql depending on which database platform you want to use.
To make that work, you'll have to configure the spring.datasource.platform
property though:
spring.datasource.platform=h2
If available you can probe the current user account with posix_geteuid
and then get the user name with posix_getpwuid
.
$username = posix_getpwuid(posix_geteuid())['name'];
If you are running in safe mode however (which is often the case when exec is disabled), then it's unlikely that your PHP process is running under anything but the default www-data
or apache
account.
Use this to get an array with the local users and the groups they are member of:
Get-LocalUser |
ForEach-Object {
$user = $_
return [PSCustomObject]@{
"User" = $user.Name
"Groups" = Get-LocalGroup | Where-Object { $user.SID -in ($_ | Get-LocalGroupMember | Select-Object -ExpandProperty "SID") } | Select-Object -ExpandProperty "Name"
}
}
To get an array with the local groups and their members:
Get-LocalGroup |
ForEach-Object {
$group = $_
return [PSCustomObject]@{
"Group" = $group.Name
"Members" = $group | Get-LocalGroupMember | Select-Object -ExpandProperty "Name"
}
}
Something that may get missed: in my chaining project, it turns out a space separated list also needs a space separated semicolon at the end.
In other words, this doesn't work:
transform: translate(50%, 50%) rotate(90deg);
but this does:
transform: translate(50%, 50%) rotate(90deg) ; //has a space before ";"
On top of what Jimmy said, you can also make the select generic by using Convert.ChangeType
along with the necessary null checks:
public T GetColumnValue<T>(DataRow row, string columnName)
{
T value = default(T);
if (row.Table.Columns.Contains(columnName) && row[columnName] != null && !String.IsNullOrWhiteSpace(row[columnName].ToString()))
{
value = (T)Convert.ChangeType(row[columnName].ToString(), typeof(T));
}
return value;
}
You can also use the setProperty method like below
document.getElementById('divName').style.setProperty("top", "100px");
Edit
It has been pointed out that there exists (at least as of 3.0) a pure Spring MVC mechanism by which one could get this data. I will not detail it here, as it is the answer of another user. See @AdamGent's answer for details, and don't forget to upvote it.
In the Spring 3.2 documentation this mechanism is mentioned on both the RequestMapping
JavaDoc page and the RequestParam
JavaDoc page, but prior, it is only mentioned in the RequestMapping
page. In 2.5 documentation there is no mention of this mechanism.
This is likely the preferred approach for most developers as it removes (at least this) binding to the HttpServletRequest
object defined by the servlet-api jar.
/Edit
You should have access to the requests query string via request.getQueryString()
.
In addition to getQueryString, the query parameters can also be retrieved from request.getParameterMap() as a Map.
Change database to single user mode as shown in the other answers
Sometimes, even after converting to single user mode, the only connection allowed to the database may be in use.
To close a connection even after converting to single user mode try:
select * from master.sys.sysprocesses
where spid>50 -- don't want system sessions
and dbid = DB_ID('BOSEVIKRAM')
Look at the results and see the ID of the connection to the database in question.
Then use the command below to close this connection (there should only be one since the database is now in single user mode)
KILL connection_ID
Replace connection_id with the ID in the results of the 1st query
If you are thinking of running a server and trying to decide how many connections can be served from one machine, you may want to read about the C10k problem and the potential problems involved in serving lots of clients simultaneously.
Find mySecondObject (of type MyObject) in combobox (containing a list of MyObjects) and select the item:
foreach (MyObject item in comboBox.Items)
{
if (item.NameOrID == mySecondObject.NameOrID)
{
comboBox.SelectedItem = item;
break;
}
}
If using Visual Studio 2010 you can right-click on the project for the service, and select properties
. Then select the Web
tab. Under the Servers
section you can configure the URL. There is also a button to create the virtual directory.
Just to keep it backward compatible I load Crockfords JSON-library from cloudflare CDN if no native JSON support is given (for simplicity using jQuery):
function winHasJSON(){
json_data = JSON.stringify(obj);
// ... (do stuff with json_data)
}
if(typeof JSON === 'object' && typeof JSON.stringify === 'function'){
winHasJSON();
} else {
$.getScript('//cdnjs.cloudflare.com/ajax/libs/json2/20121008/json2.min.js', winHasJSON)
}
You'll have to make a join:
SELECT A.SalesOrderID, B.Foo
FROM A
JOIN B bo ON bo.id = (
SELECT TOP 1 id
FROM B bi
WHERE bi.SalesOrderID = a.SalesOrderID
ORDER BY bi.whatever
)
WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'
, assuming that b.id
is a PRIMARY KEY
on B
In MS SQL 2005
and higher you may use this syntax:
SELECT SalesOrderID, Foo
FROM (
SELECT A.SalesOrderId, B.Foo,
ROW_NUMBER() OVER (PARTITION BY B.SalesOrderId ORDER BY B.whatever) AS rn
FROM A
JOIN B ON B.SalesOrderID = A.SalesOrderID
WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'
) i
WHERE rn
This will select exactly one record from B
for each SalesOrderId
.
FormData Objects: Upload Files Using Ajax
XMLHttpRequest Level 2 adds support for the new FormData interface. FormData objects provide a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XMLHttpRequest send() method.
function AjaxFileUpload() {
var file = document.getElementById("files");
//var file = fileInput;
var fd = new FormData();
fd.append("imageFileData", file);
var xhr = new XMLHttpRequest();
xhr.open("POST", '/ws/fileUpload.do');
xhr.onreadystatechange = function () {
if (xhr.readyState == 4) {
alert('success');
}
else if (uploadResult == 'success')
alert('error');
};
xhr.send(fd);
}
"Alter column position" in the PostgreSQL Wiki says:
PostgreSQL currently defines column order based on the
attnum
column of thepg_attribute
table. The only way to change column order is either by recreating the table, or by adding columns and rotating data until you reach the desired layout.
That's pretty weak, but in their defense, in standard SQL, there is no solution for repositioning a column either. Database brands that support changing the ordinal position of a column are defining an extension to SQL syntax.
One other idea occurs to me: you can define a VIEW
that specifies the order of columns how you like it, without changing the physical position of the column in the base table.
I would suggest that a definition of 'transaction processing' would be more useful, as it covers transactions as a concept in computer science.
From wikipedia:
In computer science, transaction processing is information processing that is divided into individual, indivisible operations, called transactions. Each transaction must succeed or fail as a complete unit; it cannot remain in an intermediate state.
http://en.wikipedia.org/wiki/Transaction_processing#Implementations
I had the same problem running Ubuntu 18.04. I tried multiple solutions but my device (OnePlus 5T) was always unauthorized.
Solution
Configure udev rules on Ubuntu. To do this, just follow the official documentation: https://developer.android.com/studio/run/device
The idVendor of my device (OnePlus) is not listed. To get it, just connect your device and use lsusb
:
Bus 003 Device 008: ID 2a70:4ee7
In this example, 2a70
is the idVendor.
Remove existing adb keys on Ubuntu:
rm -v ~/.android/adbkey* ~/.android/adbkey ~/.android/adbkey.pub
'Revoke USB debugging authorizations' on your device configuration (developer options).
Finally, restart the adb server to create a new key:
sudo adb kill-server
sudo adb devices
After that, I got the authorization prompt on my device and I authorized it.
As others already answered well, they both are interchangeable.
Nonetheless, it's worth mentioning that there could be a case where you may want to use the explicit statement, i.e. pointer != NULL
.

Maybe will be useful for somebody. I had a little bit another requirement. Having list of objects A
from 3rd party remove all which have same A.b
field for same A.id
(multiple A
object with same A.id
in list). Stream partition answer by Tagir Valeev inspired me to use custom Collector
which returns Map<A.id, List<A>>
. Simple flatMap
will do the rest.
public static <T, K, K2> Collector<T, ?, Map<K, List<T>>> groupingDistinctBy(Function<T, K> keyFunction, Function<T, K2> distinctFunction) {
return groupingBy(keyFunction, Collector.of((Supplier<Map<K2, T>>) HashMap::new,
(map, error) -> map.putIfAbsent(distinctFunction.apply(error), error),
(left, right) -> {
left.putAll(right);
return left;
}, map -> new ArrayList<>(map.values()),
Collector.Characteristics.UNORDERED)); }
In C# Selenium Web Driver I have managed to get it working with the following code:
var alert = TestDriver.SwitchTo().Alert();
alert.SendKeys(CurrentTestingConfiguration.Configuration.BasicAuthUser + Keys.Tab + CurrentTestingConfiguration.Configuration.BasicAuthPassword);
alert.Accept();
Although it seems similar, the following did not work with Firefox (Keys.Tab resets all the form and the password will be written within the user field):
alert.SendKeys(CurrentTestingConfiguration.Configuration.BasicAuthUser);
alert.SendKeys(Keys.Tab);
alert.SendKeys(CurrentTestingConfiguration.Configuration.BasicAuthPassword);
Also, I have tried the following solution which resulted in exception:
var alert = TestDriver.SwitchTo().Alert();
alert.SetAuthenticationCredentials(
CurrentTestingConfiguration.Configuration.BasicAuthUser,
CurrentTestingConfiguration.Configuration.BasicAuthPassword);
System.NotImplementedException: 'POST /session/38146c7c-cd1a-42d8-9aa7-1ac6837e64f6/alert/credentials did not match a known command'
The Major Difference between a Service
and an IntentService
is described as follows:
Service :
1.A Service
by default, runs on the application's main thread.(here no default worker thread is available).So the user needs to create a separate thread and do the required work in that thread.
2.Allows Multiple requests at a time.(Multi Threading)
IntentService :
1.Now, coming to IntentService
, here a default worker thread is available to perform any operation. Note that - You need to implement onHandleIntent()
method ,which receives the intent for each start request, where you can do the background work.
2.But it allows only one request at a time.

export $(cat .env | xargs) && rails c
Reason why I use this is if I want to test .env
stuff in my rails console.
gabrielf came up with a good way to keep the variables local. This solves the potential problem when going from project to project.
env $(cat .env | xargs) rails
I've tested this with bash 3.2.51(1)-release
Update:
To ignore lines that start with #
, use this (thanks to Pete's comment):
export $(grep -v '^#' .env | xargs)
And if you want to unset
all of the variables defined in the file, use this:
unset $(grep -v '^#' .env | sed -E 's/(.*)=.*/\1/' | xargs)
Update:
To also handle values with spaces, use:
export $(grep -v '^#' .env | xargs -d '\n')
on GNU systems -- or:
export $(grep -v '^#' .env | xargs -0)
on BSD systems.
From this answer you can auto-detect the OS with this:
export-env.sh
#!/bin/sh
## Usage:
## . ./export-env.sh ; $COMMAND
## . ./export-env.sh ; echo ${MINIENTREGA_FECHALIMITE}
unamestr=$(uname)
if [ "$unamestr" = 'Linux' ]; then
export $(grep -v '^#' .env | xargs -d '\n')
elif [ "$unamestr" = 'FreeBSD' ]; then
export $(grep -v '^#' .env | xargs -0)

5 Amazing Ways To Underline A TextView In Android - Kotlin/Java & XML
String html = "<u>Underline using Html.fromHtml()</u>";
textview.setText(Html.fromHtml(html));
But Html.fromHtml(String resource) was deprecated in API 24.
So you can use the latest android support library androidx.core.text.HtmlCompat. Before that, you need to include the dependency in your project.
`implementation 'androidx.core:core:1.0.1'`
String html = "<u> 1.1 Underline using HtmlCompat.fromHtml()</u>";
//underline textview using HtmlCompat.fromHtml() method
textview11.setText(HtmlCompat.fromHtml(html, HtmlCompat.FROM_HTML_MODE_LEGACY));
Using strings.xml,
<string name="underline_text">1.3 <u>Underline using HtmlCompat.fromHtml() and string resource</u></string>
textview13.setText(HtmlCompat.fromHtml(getString(R.string.underline_text), HtmlCompat.FROM_HTML_MODE_LEGACY));
using PaintFlags
textview2.setPaintFlags(textview2.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);
textview2.setText("2. Underline using setPaintFlags()");
using SpannableString
`String content1 = "3.1 Underline using SpannableString";
SpannableString spannableString1 = new SpannableString(content1);
spannableString1.setSpan(new UnderlineSpan(), 0, content1.length(), 0);
textview31.setText(spannableString1);`
this is trivially easy, why are so many people making such bad suggestions? @Bora was the closest, but this is the most robust
/***

date("F", strtotime(date("Y")."-".$month."-01"));
this is the way to do it
Along with the embed, I also had to install the Google Cast extension in my browser.
<iframe width="1280" height="720" src="https://www.youtube.com/embed/4u856utdR94" frameborder="0" allowfullscreen></iframe>
You can access the timezone by the following script:
SELECT * FROM pg_timezone_names WHERE name = current_setting('TIMEZONE');
output will be :
name- Europe/Berlin,
abbrev - CET,
utc_offset- 01:00:00,
is_dst- false
I had same issue in Android Studio 3. (the project was open) so I closed the current project and the IDE automatically prompted to download the latest components. once its done everything was working correctly.
First of all you should include ckeditor and jquery connector script in your page,
then create a textarea
<textarea name="content" class="editor" id="ms_editor"></textarea>
attach ckeditor to the text area, in my project I use something like this:
$('textarea.editor').ckeditor(function() {
}, { toolbar : [
['Cut','Copy','Paste','PasteText','PasteFromWord','-','Print', 'SpellChecker', 'Scayt'],
['Undo','Redo'],
['Bold','Italic','Underline','Strike','-','Subscript','Superscript'],
['NumberedList','BulletedList','-','Outdent','Indent','Blockquote'],
['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
['Link','Unlink','Anchor', 'Image', 'Smiley'],
['Table','HorizontalRule','SpecialChar'],
['Styles','BGColor']
], toolbarCanCollapse:false, height: '300px', scayt_sLang: 'pt_PT', uiColor : '#EBEBEB' } );
on submit get the content using:
var content = $( 'textarea.editor' ).val();
That's it! :)
There is another approach. In my example you see some business logic in repository class that I use with dependency injection in ASP .NET MVC Core 3.1.
And here I want to get connectiongString
for that business logic because probably another repository will have access to another database at all.
This pattern allows you in the same business logic repository have access to different databases.
C#

configurationRoot = configurationBuilder.Build();
}
public IEnumerable<FederalDistrict> FederalDistricts()
{
var conn = configurationRoot.GetConnectionString("EFCoreTestContext");
optionsBuilder.UseSqlServer(conn);
using (var ctx = new EFCoreTestContext(optionsBuilder.Options))
{
return ctx.FederalDistricts.Include(x => x.FederalSubjects).ToList();
}
}

For the git protocol (git://...), install socat and write a script such as:
#!/bin/sh
exec socat - socks4:your.company.com:$1:$2
make it executable, put it in your path, and in your ~/.gitconfig
set core.gitproxy
to the name of that script.
I believe this should solve your problem. I may be missing a few edge cases, please comment if you notice one.
You need a way to exclude previous substitutions from future patterns, which really means making outputs distinguishable, as well as excluding these outputs from your searches, and finally making outputs indistinguishable again. This is very similar to the quoting/escaping process, so I'll draw from it.
s/\\/\\\\/g
escapes all existing backslashess/ab/\\b\\c/g
substitutes raw ab for escaped bcs/bc/\\a\\b/g
substitutes raw bc for escaped abs/\\\(.\)/\1/g
substitutes all escaped X for raw XI have not accounted for backslashes in ab or bc, but intuitively, I would escape the search and replace terms the same way - \
now matches \\
, and substituted \\
will appear as \
.
Until now I have been using backslashes as the escape character, but it's not necessarily the best choice. Almost any character should work, but be careful with the characters that need escaping in your environment, sed, etc. depending on how you intend to use the results.
You need to add the package containing the executable pg_config.

IDisposable
exists to provide a means for you to clean up unmanaged resources that won't be cleaned up automatically by the Garbage Collector.
All of the resources that you are "cleaning up" are managed resources, and as such your Dispose
method is accomplishing nothing. Your class shouldn't implement IDisposable
at all. The Garbage Collector will take care of all of those fields just fine on its own.

You have forgotten to mark the getProducts return type as an array. In your getProducts it says that it will return a single product. So change it to this:
public getProducts(): Observable<Product[]> {
return this.http.get<Product[]>(`api/products/v1/`);
}
Another possibility is to use the options with data
attributes, like this(minimum date 1 week before):
<input class='datepicker' data-date-start-date="-1w">

You can also use OpenCV's inbuilt functions cv2.hconcat
and cv2.vconcat
which like their names suggest are used to join images horizontally and vertically respectively.
import cv2
img1 = cv2.imread('opencv/lena.jpg')
img2 = cv2.imread('opencv/baboon.jpg')
v_img = cv2.vconcat([img1, img2])
h_img = cv2.hconcat([img1, img2])
cv2.imshow('Horizontal', h_img)
cv2.imshow('Vertical', v_img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Just add this one-line class in your CSS, and use the bootstrap label
component.
.label-as-badge {
border-radius: 1em;
}
Compare this label
and badge
side by side:
<span class="label label-default label-as-badge">hello</span>
<span class="badge">world</span>
They appear the same. But in the CSS, label
uses em
so it scales nicely, and it still has all the "-color" classes. So the label will scale to bigger font sizes better, and can be colored with label-success, label-warning, etc. Here are two examples:
<span class="label label-success label-as-badge">Yay! Rah!</span>
Or where things are bigger:
<div style="font-size: 36px"><!-- pretend an enclosing class has big font size -->
<span class="label label-success label-as-badge">Yay! Rah!</span>
</div>
11/16/2015: Looking at how we'll do this in Bootstrap 4
Looks like .badge
classes are completely gone. But there's a built-in .label-pill
class (here) that looks like what we want.
.label-pill {
padding-right: .6em;
padding-left: .6em;
border-radius: 10rem;
}
In use it looks like this:
<span class="label label-pill label-default">Default</span>
<span class="label label-pill label-primary">Primary</span>
<span class="label label-pill label-success">Success</span>
<span class="label label-pill label-info">Info</span>
<span class="label label-pill label-warning">Warning</span>
<span class="label label-pill label-danger">Danger</span>
11/04/2014: Here's an update on why cross-pollinating alert classes with .badge
is not so great. I think this picture sums it up:
Those alert classes were not designed to go with badges. It renders them with a "hint" of the intended colors, but in the end consistency is thrown out the window and readability is questionable. Those alert-hacked badges are not visually cohesive.
The .label-as-badge
solution is only extending the bootstrap design. We are keeping intact all the decision making made by the bootstrap designers, namely the consideration they gave for readability and cohesion across all the possible colors, as well as the color choices themselves. The .label-as-badge
class only adds rounded corners, and nothing else. There are no color definitions introduced. Thus, a single line of CSS.
Yep, it is easier to just hack away and drop in those .alert-xxxxx
classes -- you don't have to add any lines of CSS. Or you could care more about the little things and add one line.
If you want to know the day of the week for your code to do something with it, DateTime.Now.DayOfWeek

Your file needs to be located inside your www directory. For example, if you're using wamp server on Windows, j3evn.jpg should be located,
C:/wamp/www/img/j3evn.jpg
and you can access it in html via
<img class="sealImage" alt="Image of Seal" src="../img/j3evn.jpg">
Look for the www, public_html, or html folder belonging to your web server. Place all your files and resources inside that folder.

If there are two instances of MySql it's normal that it gives such an error if they both run at the same time. If you really need 2 servers, you must change the listening port of one of them, or if you don't it's probably better to simply uninstall one of them. This is so regarless of MySql itself, because two programs cannot listen on the same port at the same time.

AFAIK, there's no clean way to implement a "logout" function when using htaccess (i.e. HTTP-based) authentication.
This is because such authentication uses the HTTP error code '401' to tell the browser that credentials are required, at which point the browser prompts the user for the details. From then on, until the browser is closed, it will always send the credentials without further prompting.

Android follows normal java package conventions plus here is an important snippet of text to read (this is important regarding the wide use of xml files while developing on android).
The reason for having it in reverse order is to do with the layout on the storage media. If you consider each period ('.') in the application name as a path separator, all applications from a publisher would sit together in the path hierarchy. So, for instance, packages from Adobe would be of the form:
com.adobe.reader (Adobe Reader)
com.adobe.photoshop (Adobe Photoshop)
com.adobe.ideas (Adobe Ideas)
[Note that this is just an illustration and these may not be the exact package names.]
These could internally be mapped (respectively) to:
com/adobe/reader
com/adobe/photoshop
com/adobe/ideas
The concept comes from Package Naming Conventions in Java, more about which can be read here:*
http://en.wikipedia.org/wiki/Java_package#Package_naming_conventions
Source: http://www.quora.com/Why-do-a-majority-of-Android-package-names-begin-with-com
When you are passing the custom request in the controller method, and your request file doesn't follow the proper syntax or table name is changed, then laravel through this type of exception. I'll show you in Example.

OR

Last three characters of string
:
${string: -3}
or
${string:(-3)}
(mind the space between :
and -3
in the first form).
Please refer to the Shell Parameter Expansion in the reference manual:
${parameter:offset}
${parameter:offset:length}
Expands to up to length characters of parameter starting at the character
specified by offset. If length is omitted, expands to the substring of parameter
starting at the character specified by offset. length and offset are arithmetic
expressions (see Shell Arithmetic). This is referred to as Substring Expansion.
If offset evaluates to a number less than zero, the value is used as an offset
from the end of the value of parameter. If length evaluates to a number less than
zero, and parameter is not ‘@’ and not an indexed or associative array, it is
interpreted as an offset from the end of the value of parameter rather than a
number of characters, and the expansion is the characters between the two
offsets. If parameter is ‘@’, the result is length positional parameters
beginning at offset. If parameter is an indexed array name subscripted by ‘@’ or
‘*’, the result is the length members of the array beginning with
${parameter[offset]}. A negative offset is taken relative to one greater than the
maximum index of the specified array. Substring expansion applied to an
associative array produces undefined results.
Note that a negative offset must be separated from the colon by at least one
space to avoid being confused with the ‘:-’ expansion. Substring indexing is
zero-based unless the positional parameters are used, in which case the indexing
starts at 1 by default. If offset is 0, and the positional parameters are used,
$@ is prefixed to the list.
Since this answer gets a few regular views, let me add a possibility to address John Rix's comment; as he mentions, if your string has length less than 3, ${string: -3}
expands to the empty string. If, in this case, you want the expansion of string
, you may use:
${string:${#string}<3?0:-3}
This uses the ?:
ternary if operator, that may be used in Shell Arithmetic; since as documented, the offset is an arithmetic expression, this is valid.
The previous part gives the best option when using Bash. If you want to target POSIX shells, here's an option (that doesn't use pipes or external tools like cut
):
# New variable with 3 last characters removed
prefix=${string%???}
# The new string is obtained by removing the prefix a from string
newstring=${string#"$prefix"}
One of the main things to observe here is the use of quoting for prefix
inside the parameter expansion. This is mentioned in the POSIX ref (at the end of the section):
The following four varieties of parameter expansion provide for substring processing. In each case, pattern matching notation (see Pattern Matching Notation), rather than regular expression notation, shall be used to evaluate the patterns. If parameter is '#', '*', or '@', the result of the expansion is unspecified. If parameter is unset and set -u is in effect, the expansion shall fail. Enclosing the full parameter expansion string in double-quotes shall not cause the following four varieties of pattern characters to be quoted, whereas quoting characters within the braces shall have this effect. In each variety, if word is omitted, the empty pattern shall be used.
This is important if your string contains special characters. E.g. (in dash),
$ string="hello*ext"
$ prefix=${string%???}
$ # Without quotes (WRONG)
$ echo "${string#$prefix}"
*ext
$ # With quotes (CORRECT)
$ echo "${string#"$prefix"}"
ext
Of course, this is usable only when then number of characters is known in advance, as you have to hardcode the number of ?
in the parameter expansion; but when it's the case, it's a good portable solution.
Derek's solution worked fine for me, and I've just simply converted it to PHP, hope it helps somebody out there !
function calcCrow($lat1, $lon1, $lat2, $lon2){

$dLat = toRad($lat2-$lat1);
$dLon = toRad($lon2-$lon1);
$lat1 = toRad($lat1);
$lat2 = toRad($lat2);
$a = sin($dLat/2) * sin($dLat/2) +sin($dLon/2) * sin($dLon/2) * cos($lat1) * cos($lat2);
$c = 2 * atan2(sqrt($a), sqrt(1-$a));
$d = $R * $c;
return $d;
}
// Converts numeric degrees to radians

If you want to make the reverse of what you showed consider doing this:
.tint:hover:before {

}
and look at the effect on the 2nd picture.
Is it supposed to look like this?
I'd just like to detail a few things in Greg Hewgil's accepted answer. According to the Git Pocket Guide
Branch:
the branch itself is defined as all points reachable in the commit graph from the named commit (the “tip” of the branch).
HEAD: A special type of Ref
The special ref HEAD determines what branch you are on...
Refs
Git defines two kinds of references, or named pointers, which it calls “refs”:
- A simple ref, which points directly to an object ID (usually a commit or tag)
- A symbolic ref (or symref), which points to another ref (either simple or symbolic)
As Greg mentioned, HEAD can be in a "detached state". So HEAD can be either a simple ref (for a detached HEAD) or a symref.
if HEAD is a symbolic ref for an existing branch, then you are “on” that branch. If, on the other hand, HEAD is a simple ref directly naming a commit by its SHA-1 ID, then you are not “on” any branch, but rather in “detached HEAD” mode, which happens when you check out some earlier commit to examine.

For simple usage I made a function that encodes the input string (binary data):
/* Encodes string to hexadecimal string reprsentation
Allocates a new memory for supplied lpszOut that needs to be deleted after use
Fills the supplied lpszOut with hexadecimal representation of the input
*/
void StringToHex(unsigned char *szInput, size_t size_szInput, char **lpszOut)
{
unsigned char *pin = szInput;
const char *hex = "0123456789ABCDEF";
size_t outSize = size_szInput * 2 + 2;
*lpszOut = new char[outSize];
char *pout = *lpszOut;
for (; pin < szInput + size_szInput; pout += 2, pin++)
{
pout[0] = hex[(*pin >> 4) & 0xF];
pout[1] = hex[*pin & 0xF];
}
pout[0] = 0;
}
Usage:
unsigned char input[] = "This is a very long string that I want to encode";
char *szHexEncoded = NULL;
StringToHex(input, strlen((const char *)input), &szHexEncoded);
printf(szHexEncoded);
// The allocated memory needs to be deleted after usage
delete[] szHexEncoded;
This works well
2014 March: Truncating long strings with CSS: a new answer with focus on browser support
Demo on http://jsbin.com/leyukama/1/ (I use jsbin because it supports old version of IE).
<style type="text/css">
span {
display: inline-block;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis; /** IE6+, Firefox 7+, Opera 11+, Chrome, Safari **/
-o-text-overflow: ellipsis; /** Opera 9 & 10 **/
width: 370px; /* note that this width will have to be smaller to see the effect */
}
</style>
<span>Some very long text that should be cut off at some point coz it's a bit too long and the text overflow ellipsis feature is used</span>
The -ms-text-overflow CSS property is not necessary: it is a synonym of the text-overflow CSS property, but versions of IE from 6 to 11 already support the text-overflow CSS property.
Successfully tested (on Browserstack.com) on Windows OS, for web browsers:
Firefox: as pointed out by Simon Lieschke (in another answer), Firefox only support the text-overflow CSS property from Firefox 7 onwards (released September 27th 2011).
I double checked this behavior on Firefox 3.0 & Firefox 6.0 (text-overflow is not supported).
Some further testing on a Mac OS web browsers would be needed.
Note: you may want to show a tooltip on mouse hover when an ellipsis is applied, this can be done via javascript, see this questions: HTML text-overflow ellipsis detection and HTML - how can I show tooltip ONLY when ellipsis is activated
Resources:
Consider following code
<ul id="myTask">
<li>Coding</li>
<li>Answering</li>
<li>Getting Paid</li>
</ul>
Now, here goes the difference
// Remove the myTask item when clicked.
$('#myTask').children().click(function () {
$(this).remove()
});
Now, what if we add a myTask again?
$('#myTask').append('<li>Answer this question on SO</li>');
Clicking this myTask item will not remove it from the list, since it doesn't have any event handlers bound. If instead we'd used .on
, the new item would work without any extra effort on our part. Here's how the .on version would look:
$('#myTask').on('click', 'li', function (event) {
$(event.target).remove()
});
Summary:
The difference between .on()
and .click()
would be that .click()
may not work when the DOM elements associated with the .click()
event are added dynamically at a later point while .on()
can be used in situations where the DOM elements associated with the .on()
call may be generated dynamically at a later point.

You just have to install the nuget and then do a build. The final executable will be standalone.
I created a simple Objective C wrapper around the good old C array to be used more conveniently: https://gist.github.com/4705733
This is what I use in my application:
static void Main()
{
bool mutexCreated = false;
System.Threading.Mutex mutex = new System.Threading.Mutex( true, @"Local\slimCODE.slimKEYS.exe", out mutexCreated );
if( !mutexCreated )
{
if( MessageBox.Show(
"slimKEYS is already running. Hotkeys cannot be shared between different instances. Are you sure you wish to run this second instance?",
"slimKEYS already running",
MessageBoxButtons.YesNo,
MessageBoxIcon.Question ) != DialogResult.Yes )
{
mutex.Close();
return;
}
}
// The usual stuff with Application.Run()
mutex.Close();
}
z-index
only applies to elements that have been given an explicit position. Add position:relative
to #popupContent and you should be good to go.
The official naming conventions aren't that strict, they don't even 'forbid' camel case notation except for prefix (com
in your example).
But I personally would avoid upper case letters and hyphenations, even numbers. I'd choose com.stackoverflow.mypackage
like Bragboy suggested too.
(hyphenations '-' are not legal in package names)
EDIT
Interesting - the language specification has something to say about naming conventions too.
In Chapter 7.7 Unique Package Names we see examples with package names that consist of upper case letters (so CamelCase notation would be OK) and they suggest to replace hyphonation by an underscore ("mary-lou" -> "mary_lou") and prefix java keywords with an underscore ("com.example.enum" -> "com.example._enum")
Some more examples for upper case letters in package names can be found in chapter 6.8.1 Package Names.
I'm sure that the above answers work perfectly. However, I had the difficulty of adding the double quotes as my bash lines where closer to 100. So, the following way helped me. (In a nutshell, no double quotes around each line of the shell)
Also, when I had "bash '''#!/bin/bash" within steps, I got the following error java.lang.NoSuchMethodError: No such DSL method '**bash**' found among steps
pipeline {
agent none
stages {
stage ('Hello') {
agent any
steps {
echo 'Hello, '
sh '''#!/bin/bash
echo "Hello from bash"
echo "Who I'm $SHELL"
'''
}
}
}
}
The result of the above execution is
Yes even I got the same error. So I did the following changes
-> Check the error in the Problems tab located near the Console tab
-> See where the error persists, Its possible that some jar file may be corrupted or is outdated so, pom isn't activated in the Project.
-> I found one of my jar was outdated version so I updated it by getting the dependencies from maven repository from this link https://mvnrepository.com
So to conclude, do check where the error persist and which jar file is outdated and make changes accordingly
On Debian 9 I had to:
$ sudo update-ca-certificates --fresh
$ export SSL_CERT_DIR=/etc/ssl/certs
I'm not sure why, but this enviroment variable was never set.
The correct way to change directories is actually with process.chdir(directory)
. Here's an example from the documentation:
console.log('Starting directory: ' + process.cwd());
try {
process.chdir('/tmp');
console.log('New directory: ' + process.cwd());
}
catch (err) {
console.log('chdir: ' + err);
}
This is also testable in the Node.js REPL:
[monitor@s2 ~]$ node
> process.cwd()
'/home/monitor'
> process.chdir('../');
undefined
> process.cwd();
'/home'
You typically have to do this in a single syscall, or else you will get a race condition.
This will open for reading and writing, creating the file if necessary.
FILE *fp = fopen("scores.dat", "ab+");
If you want to read it and then write a new version from scratch, then do it as two steps.
FILE *fp = fopen("scores.dat", "rb");
if (fp) {
read_scores(fp);
}
// Later...
// truncates the file
FILE *fp = fopen("scores.dat", "wb");
if (!fp)
error();
write_scores(fp);
It means "not equal to" (as in, the values in cells E37-N37 are not equal to ""
, or in other words, they are not empty.)
Check if pip has been cached on another path, to do so, call $ which pip and check that the path is different from the one prompted in the error, if that's the case run:
$ hash -r
When the cache is clear, pip will be working again. reference: http://cheng.logdown.com/posts/2015/06/14/-usr-bin-pip-no-such-file-or-directory
Regex was proposed already, but not correctly:
<?php
$number = '00000004523423400023402340240';
$withoutLeadingZeroes = preg_replace('/^0+/', '', $number)
echo $withoutLeadingZeroes;
?>
output is then:
4523423400023402340240
Background on Regex:
the ^
signals beginning of string and the +
sign signals more or none of the preceding sign. Therefore, the regex ^0+
matches all zeroes at the beginning of a string.
In bootstrap 3, this works well for me:
.btn-link.btn-anchor {
outline: none !important;
padding: 0;
border: 0;
vertical-align: baseline;
}
Used like:
<button type="button" class="btn-link btn-anchor">My Button</button>
In my case, one of my closing parenthesis for "onChanges()" were missed on the input element and thus the input element was apparently not being rendered at all:
<input mat-menu-item
matInput type="text"
[formControl]="myFormControl"
(ngModelChange)="onChanged()>
To mark as obsolete with a warning:
[Obsolete]
private static void SomeMethod()
You get a warning when you use it:
And with IntelliSense:
If you want a message:
[Obsolete("My message")]
private static void SomeMethod()
Here's the IntelliSense tool tip:
Finally if you want the usage to be flagged as an error:
[Obsolete("My message", true)]
private static void SomeMethod()
When used this is what you get:
Note: Use the message to tell people what they should use instead, not why it is obsolete.
Actually, you need to update your repo first, then an upgrade of your Glibc can fix this issue.
If you want to specifically use java ArrayList then you can do something like this:
fun initList(){
val list: ArrayList<String> = ArrayList()
list.add("text")
println(list)
}
Otherwise @guenhter answer is the one you are looking for.
user287724's answer gives the following example of the book and author relationship:
A book however is written by an author, and the author could have written multiple books. But the book needs to be written by an author it cannot exist without an author. Therefore the relationship between the book and the author is an identifying relationship.
This is a very confusing example and is definitely not a valid example for an identifying relationship
.
Yes, a book
can not be written without at least one author
, but the author
(it's foreign key) of the book
is NOT IDENTIFYING the book
in the books
table!
You can remove the author
(FK) from the book
row and still can identify the book row by some other field (ISBN
, ID
, ...etc) , BUT NOT the author of the book!!
I think a valid example of an identifying relationship
would be the relationship between (products table) and a (specific product details table) 1:1
products table
+------+---------------+-------+--------+
|id(PK)|Name |type |amount |
+------+---------------+-------+--------+
|0 |hp-laser-510 |printer|1000 |
+------+---------------+-------+--------+
|1 |viewsonic-10 |screen |900 |
+------+---------------+-------+--------+
|2 |canon-laser-100|printer|200 |
+------+---------------+-------+--------+
printers_details table
+--------------+------------+---------+---------+------+
|Product_ID(FK)|manufacturer|cartridge|color |papers|
+--------------+------------+---------+---------+------+
|0 |hp |CE210 |BLACK |300 |
+--------------+------------+---------+---------+------+
|2 |canon |MKJ5 |COLOR |900 |
+--------------+------------+---------+---------+------+
* please note this is not real data
In this example the Product_ID
in the printers_details
table is considered a FK references the products.id
table and ALSO a PK in the printers_details
table , this is an identifying relationship because the Product_ID
(FK) in the printers table IS IDENTIFYING the row inside the child table, we can't remove the product_id
from the child table because we can't identify the row any more because we lost it's primary key
If you want to put it in 2 lines:
an identifying relationship is the relationship when the FK in the child table is considered a PK(or identifier) in the child table while still references the parent table
Another example may be when you have 3 tables (imports - products - countries) in an imports and exports for some country database
The import
table is the child that has these fields(the product_id
(FK), the country_id
(FK) , the amount of the imports , the price , the units imported , the way of transport(air, sea) )
we may use the (
product_id, the
country_id`) to identify each row of the imports "if they all in the same year" here the both columns can compose together a primary key in the child table(imports) and also referencing there parent tables.
Please I'm happy I finally understand the concept of the identifying relationship
and non identifying relationship
, so please don't tell me I'm wrong with all of these vote ups for a completely invalid example
Yes logically a book can't be written without an author but a book can be identified without the author,In fact it can't be identified with the author!
You can 100% remove the author from the book row and still can identify the book!.
You could try like this, for single array
irb(main):019:0> a = ["item 1", "item 2", "item 3", "item 4"]
=> ["item 1", "item 2", "item 3", "item 4"]
irb(main):020:0> Hash[*a]
=> {"item 1"=>"item 2", "item 3"=>"item 4"}
for array of array
irb(main):022:0> a = [[1, 2], [3, 4]]
=> [[1, 2], [3, 4]]
irb(main):023:0> Hash[*a.flatten]
=> {1=>2, 3=>4}
for me it was just lack of ()
in @Injectable. Proper is @Injectable()

This should do the trick:
<% if (typeof(date) !== "undefined") { %>
<span class="date"><%= date %></span>

SELECT 'tbd_robot' AS `set`, t.*
FROM tbd_robot t
WHERE ROW(t.col1, t.col2, …) NOT IN

Take a look at Enumerable#each_slice:
foo.each_slice(3).to_a
#=> [["1", "2", "3"], ["4", "5", "6"], ["7", "8", "9"], ["10"]]
For a search routine you should look to use Find
, AutoFilter
or variant array approaches. Range loops are nomally too slow, worse again if they use Select
The code below will look for the strText variable in a user selected range, it then adds any matches to a range variable rng2
which you can then further process
Option Explicit
Const strText As String = "%"
Sub ColSearch_DelRows()
Dim rng1 As Range
Dim rng2 As Range
Dim rng3 As Range
Dim cel1 As Range
Dim cel2 As Range
Dim strFirstAddress As String
Dim lAppCalc As Long
'Get working range from user
On Error Resume Next
Set rng1 = Application.InputBox("Please select range to search for " & strText, "User range selection", Selection.Address(0, 0), , , , , 8)
On Error GoTo 0
If rng1 Is Nothing Then Exit Sub
With Application
lAppCalc = .Calculation
.ScreenUpdating = False
.Calculation = xlCalculationManual
End With
Set cel1 = rng1.Find(strText, , xlValues, xlPart, xlByRows, , False)
'A range variable - rng2 - is used to store the range of cells that contain the string being searched for
If Not cel1 Is Nothing Then
Set rng2 = cel1
strFirstAddress = cel1.Address
Do
Set cel1 = rng1.FindNext(cel1)
Set rng2 = Union(rng2, cel1)
Loop While strFirstAddress <> cel1.Address
End If
If Not rng2 Is Nothing Then
For Each cel2 In rng2
Debug.Print cel2.Address & " contained " & strText
Next
Else
MsgBox "No " & strText

The project configuration file angular.json
is able to handle multiple projects (workspaces) which can be individually served.
ng config projects.my-test-project.targets.serve.options.port 4201
Where the my-test-project
part is the project name what you set with the ng new
command just like here:
$ ng new my-test-project
$ cd my-test-project
$ ng config projects.my-test-project.targets.serve.options.port 4201
$ ng serve
** Angular Live Development Server is listening on localhost:4201, open your browser on http://localhost:4201/ **
Legacy:
I usually use the ng set
command to change the Angular CLI settings for project level.
ng set defaults.serve.port=4201
It changes change your .angular.cli.json and adds the port settings as it mentioned earlier.
After this change you can use simply ng serve
and it going to use the prefered port without the need of specifying it every time.
Aapt2, included in the Android SDK build tools can do this - no third party tools needed.
$(ANDROID_SDK)/build-tools/28.0.3/aapt2 d --file AndroidManifest.xml app-foo-release.apk
Starting with build-tools v29 you have to add the command xmltree
:
$(ANDROID_SDK)/build-tools/29.0.3/aapt2 d xmltree --file AndroidManifest.xml app-foo-release.apk
MVC defaults to DenyGet
to protect you against a very specific attack involving JSON requests to improve the liklihood that the implications of allowing HTTP GET
exposure are considered in advance of allowing them to occur.
This is opposed to afterwards when it might be too late.
Note: If your action method does not return sensitive data, then it should be safe to allow the get.
Further reading from my Wrox ASP.NET MVC3 book
By default, the ASP.NET MVC framework does not allow you to respond to an HTTP GET request with a JSON payload. If you need to send JSON in response to a GET, you'll need to explicitly allow the behavior by using JsonRequestBehavior.AllowGet as the second parameter to the Json method. However, there is a chance a malicious user can gain access to the JSON payload through a process known as JSON Hijacking. You do not want to return sensitive information using JSON in a GET request. For more details, see Phil's post at http://haacked.com/archive/2009/06/24/json-hijacking.aspx/ or this SO post.

If you only want to display then you can use date pipe in HTML like this :
Just Date:
your date | date: 'dd MMM yyyy'
Date With Time:
your date | date: 'dd MMM yyyy hh:mm a'
And if you want to take input only date from new Date() then :
You can use angular formatDate() in ts file like this -
currentDate = new Date();
const cValue = formatDate(currentDate, 'yyyy-MM-dd', 'en-US');
You need a SMTP server to send your mail. If you have one available which does not require SMTP authentification (maybe your ISP's?) just edit the 'SMTP' ([mail function]) setting in your php.ini file.
If this is no option because your SMTP server requires authentification you won't be able to use the internal mail() function and have to use some 3rd party class which supports smtp auth. e.g. http://pear.php.net/package/Mail/
if ($("#Password").val() != $("#ConfirmPassword").val()) {
alert("Passwords do not match.");
}
A JQuery approach that will eliminate needless code.
Another example : I use it to group Data by date. But some data don't have date. I can group it with the header "NoDate"
I always use like this:
if (mystr != null && !mystr.isEmpty()){
//DO WHATEVER YOU WANT OR LEAVE IT EMPTY
}else {
//DO WHATEVER YOU WANT OR LEAVE IT EMPTY
}
or you can copy this to your project:
private boolean isEmptyOrNull(String mystr){
if (mystr != null && !mystr.isEmpty()){ return true; }
else { return false; }
}
and just call it like :
boolean b = isEmptyOrNull(yourString);
it will return true if is empty or null.b=true
if is empty or null
or you can use try catch and catch when it is null.

Just invoke ruby XXXXX.rb

( this can hardly be a rails thing, until you have it running. )
You can also draw the string dynamically inside the RowPostPaint
event:
private void dgGrid_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
var grid = sender as DataGridView;
var rowIdx = (e.RowIndex + 1).ToString();
var centerFormat = new StringFormat()
{
// right alignment might actually make more sense for numbers
Alignment = StringAlignment.Center,
LineAlignment = StringAlignment.Center
};
var headerBounds = new Rectangle(e.RowBounds.Left, e.RowBounds.Top, grid.RowHeadersWidth, e.RowBounds.Height);
e.Graphics.DrawString(rowIdx, this.Font, SystemBrushes.ControlText, headerBounds, centerFormat);
}
Since the question was "display" :
@Html.ValueFor(model => model.RegistrationDate, "{0:dd/MM/yyyy}")
If the string is empty, comboBox.getSelectedItem().toString()
will give a NullPointerException
. So better to typecast by (String)
.
I use this simple utility function:
rows = function(tab) lapply(
seq_len(nrow(tab)),
function(i) unclass(tab[i,,drop=F])
)
Or a faster, less clear form:
rows = function(x) lapply(seq_len(nrow(x)), function(i) lapply(x,"[",i))
This function just splits a data.frame to a list of rows. Then you can make a normal "for" over this list:
tab = data.frame(x = 1:3, y=2:4, z=3:5)
for (A in rows(tab)) {
print(A$x + A$y * A$z)
}
Your code from the question will work with a minimal modification:
for (well in rows(dataFrame)) {
wellName <- well$name # string like "H1"
plateName <- well$plate # string like "plate67"
wellID <- getWellID(wellName, plateName)
cat(paste(wellID, well$value1, well$value2, sep=","), file=outputFile)
}
I downloaded the jar file manually and replace the one in my local directory and it worked
It turns out that, out of the four possible permutations of including or excluding trailing or leading forward slashes on the BaseAddress
and the relative URI passed to the GetAsync
method -- or whichever other method of HttpClient
-- only one permutation works. You must place a slash at the end of the BaseAddress
, and you must not place a slash at the beginning of your relative URI, as in the following example.
using (var handler = new HttpClientHandler())
using (var client = new HttpClient(handler))
{
client.BaseAddress = new Uri("http://something.com/api/");
var response = await client.GetAsync("resource/7");
}
Even though I answered my own question, I figured I'd contribute the solution here since, again, this unfriendly behavior is undocumented. My colleague and I spent most of the day trying to fix a problem that was ultimately caused by this oddity of HttpClient
.
The answer I was looking for is at https://unix.stackexchange.com/a/9557/114862.
Using the

flag when the local file is of greater or equal size to the server version will avoid re-downloading.
The copy constructor given by @Stephen C is the way to go when you have a Set
you created (or when you know where it comes from).
When it comes from a Map.entrySet()
, it will depend on the Map
implementation you're using:
findbugs says
The entrySet() method is allowed to return a view of the underlying Map in which a single Entry object is reused and returned during the iteration. As of Java 1.6, both IdentityHashMap and EnumMap did so. When iterating through such a Map, the Entry value is only valid until you advance to the next iteration. If, for example, you try to pass such an entrySet to an addAll method, things will go badly wrong.
As addAll()
is called by the copy constructor, you might find yourself with a Set of only one Entry: the last one.
Not all Map
implementations do that though, so if you know your implementation is safe in that regard, the copy constructor definitely is the way to go. Otherwise, you'd have to create new Entry
objects yourself:
Set<K,V> copy = new HashSet<K,V>(map.size());
for (Entry<K,V> e : map.entrySet())
copy.add(new java.util.AbstractMap.SimpleEntry<K,V>(e));
Edit: Unlike tests I performed on Java 7 and Java 6u45 (thanks to Stephen C), the findbugs comment does not seem appropriate anymore. It might have been the case on earlier versions of Java 6 (before u45) but I don't have any to test.
nan
means "not a number", a float value that you get if you perform a calculation whose result can't be expressed as a number. Any calculations you perform with NaN
will also result in NaN
.
inf
means infinity.
For example:
>>> 2*float("inf")
inf
>>> -2*float("inf")
-inf
>>> float("inf")-float("inf")

What you need (for tic-tac-toe or a far more difficult game like Chess) is the minimax algorithm, or its slightly more complicated variant, alpha-beta pruning. Ordinary naive minimax will do fine for a game with as small a search space as tic-tac-toe, though.
In a nutshell, what you want to do is not to search for the move that has the best possible outcome for you, but rather for the move where the worst possible outcome is as good as possible. If you assume your opponent is playing optimally, you have to assume they will take the move that is worst for you, and therefore you have to take the move that MINimises their MAXimum gain.

Previous answers are correct: adding the line...
Response.AddHeader("Content-Disposition", "inline; filename=[filename]");
...will causing multiple Content-Disposition headers to be sent down to the browser. This happens b/c FileContentResult
internally applies the header if you supply it with a file name. An alternative, and pretty simple, solution is to simply create a subclass of FileContentResult
and override its ExecuteResult()
method. Here's an example that instantiates an instance of the System.Net.Mime.ContentDisposition
class (the same object used in the internal FileContentResult
implementation) and passes it into the new class:
public class FileContentResultWithContentDisposition : FileContentResult
{
private const string ContentDispositionHeaderName = "Content-Disposition";
public FileContentResultWithContentDisposition(byte[] fileContents, string contentType, ContentDisposition contentDisposition)
: base(fileContents, contentType)
{
// check for null or invalid ctor arguments
ContentDisposition = contentDisposition;
}
public ContentDisposition ContentDisposition { get; private set; }
public override void ExecuteResult(ControllerContext context)
{
// check for null or invalid method argument
ContentDisposition.FileName = ContentDisposition.FileName ?? FileDownloadName;
var response = context.HttpContext.Response;
response.ContentType = ContentType;
response.AddHeader(ContentDispositionHeaderName, ContentDisposition.ToString());
WriteFile(response);
}
}
In your Controller
, or in a base Controller
, you can write a simple helper to instantiate a FileContentResultWithContentDisposition
and then call it from your action method, like so:
protected virtual FileContentResult File(byte[] fileContents, string contentType, ContentDisposition contentDisposition)
{
var result = new FileContentResultWithContentDisposition(fileContents, contentType, contentDisposition);
return result;
}
public ActionResult Report()
{
// get a reference to your document or file
// in this example the report exposes properties for
// the byte[] data and content-type of the document
var report = ...
return File(report.Data, report.ContentType, new ContentDisposition {
Inline = true,
FileName = report.FileName
});
}
Now the file will be sent to the browser with the file name you choose and with a content-disposition header of "inline; filename=[filename]".
I hope that helps!
Merlin's answer is better and super easy, but we don't need a lambda function. The evaluation of dictionary can be safely ignored by either of the following two ways as illustrated below:
Way 1: Two steps
# step 1: convert the `Pollutants` column to Pandas dataframe series
df_pol_ps = data_df['Pollutants'].apply(pd.Series)
df_pol_ps:
a b c
0 46 3 12
1 36 5 8
2 NaN 2 7
3 NaN NaN 11
4 82 NaN 15
# step 2: concat columns `a, b, c` and drop/remove the `Pollutants`
df_final = pd.concat([df, df_pol_ps], axis = 1).drop('Pollutants', axis = 1)
df_final:
StationID a b c
0 8809 46 3 12
1 8810 36 5 8
2 8811 NaN 2 7
3 8812 NaN NaN 11
4 8813 82 NaN 15
Way 2: The above two steps can be combined in one go:
df_final = pd.concat([df, df['Pollutants'].apply(pd.Series)], axis = 1).drop('Pollutants', axis = 1)
df_final:
StationID a b c
0 8809 46 3 12
1 8810 36 5 8
2 8811 NaN 2 7
3 8812 NaN NaN 11
4 8813 82 NaN 15
Configuring the CORS response headers on the server wasn't really an option. You should configure a proxy in client side.
Sample to Angular - So, I created a proxy.conf.json file to act as a proxy server. Below is my proxy.conf.json file:

Put the file in the same directory the package.json then I modified the start command in the package.json file like below
"start": "ng serve --proxy-config proxy.conf.json"
now, the http call from the app component is as follows:
return this.http.get('/api/customers').map((res: Response) => res.json());
Lastly to run use npm start or ng serve --proxy-config proxy.conf.json
Try this. I've use the Large Object Binary (LOB) format for storing generated PDF documents, some of which were 10+ MB in size, in a database and it worked wonderfully.
ON [PRIMARY] will create the structures on the "Primary" filegroup. In this case the primary key index and the table will be placed on the "Primary" filegroup within the database.
If you want to allow the user to browse for a file, you need to have an input type="file"
The closest you could get to your requirement would be to place the input type="file"
on the page and hide it. Then, trigger the click event of the input when the button is clicked:
#myFileInput {
display:none;
}
<input type="file" id="myFileInput" />
<input type="button"
onclick="document.getElementById('myFileInput').click()"
value="Select a File" />
Here's a working fiddle.
Note: I would not recommend this approach. The input type="file"
is the mechanism that users are accustomed to using for uploading a file.
