You should not use your domain models
in your views. ViewModels
are the correct way to do it.
You need to map your domain model's necessary fields to viewmodel and then use this viewmodel in your controllers. This way you will have the necessery abstraction in your application.
If you never heard of viewmodels, take a look at this.
This post aims to give readers a primer on SQL-flavored merging with pandas, how to use it, and when not to use it.
In particular, here's what this post will go through:
The basics - types of joins (LEFT, RIGHT, OUTER, INNER)
What this post (and other posts by me on this thread) will not go through:
Note
Most examples default to INNER JOIN operations while demonstrating various features, unless otherwise specified.Furthermore, all the DataFrames here can be copied and replicated so you can play with them. Also, see this post on how to read DataFrames from your clipboard.
Lastly, all visual representation of JOIN operations have been hand-drawn using Google Drawings. Inspiration from here.
merge
!np.random.seed(0)
left = pd.DataFrame({'key': ['A', 'B', 'C', 'D'], 'value': np.random.randn(4)})
right = pd.DataFrame({'key': ['B', 'D', 'E', 'F'], 'value': np.random.randn(4)})
left
key value
0 A 1.764052
1 B 0.400157
2 C 0.978738
3 D 2.240893
right
key value
0 B 1.867558
1 D -0.977278
2 E 0.950088
3 F -0.151357
For the sake of simplicity, the key column has the same name (for now).
An INNER JOIN is represented by
Note
This, along with the forthcoming figures all follow this convention:
- blue indicates rows that are present in the merge result
- red indicates rows that are excluded from the result (i.e., removed)
- green indicates missing values that are replaced with
NaN
s in the result
To perform an INNER JOIN, call merge
on the left DataFrame, specifying the right DataFrame and the join key (at the very least) as arguments.
left.merge(right, on='key')
# Or, if you want to be explicit
# left.merge(right, on='key', how='inner')
key value_x value_y
0 B 0.400157 1.867558
1 D 2.240893 -0.977278
This returns only rows from left
and right
which share a common key (in this example, "B" and "D).
A LEFT OUTER JOIN, or LEFT JOIN is represented by
This can be performed by specifying how='left'
.
left.merge(right, on='key', how='left')
key value_x value_y
0 A 1.764052 NaN
1 B 0.400157 1.867558
2 C 0.978738 NaN
3 D 2.240893 -0.977278
Carefully note the placement of NaNs here. If you specify how='left'
, then only keys from left
are used, and missing data from right
is replaced by NaN.
And similarly, for a RIGHT OUTER JOIN, or RIGHT JOIN which is...
...specify how='right'
:
left.merge(right, on='key', how='right')
key value_x value_y
0 B 0.400157 1.867558
1 D 2.240893 -0.977278
2 E NaN 0.950088
3 F NaN -0.151357
Here, keys from right
are used, and missing data from left
is replaced by NaN.
Finally, for the FULL OUTER JOIN, given by
specify how='outer'
.
left.merge(right, on='key', how='outer')
key value_x value_y
0 A 1.764052 NaN
1 B 0.400157 1.867558
2 C 0.978738 NaN
3 D 2.240893 -0.977278
4 E NaN 0.950088
5 F NaN -0.151357
This uses the keys from both frames, and NaNs are inserted for missing rows in both.
The documentation summarizes these various merges nicely:
If you need LEFT-Excluding JOINs and RIGHT-Excluding JOINs in two steps.
For LEFT-Excluding JOIN, represented as
Start by performing a LEFT OUTER JOIN and then filtering (excluding!) rows coming from left
only,
(left.merge(right, on='key', how='left', indicator=True)
.query('_merge == "left_only"')
.drop('_merge', 1))
key value_x value_y
0 A 1.764052 NaN
2 C 0.978738 NaN
Where,
left.merge(right, on='key', how='left', indicator=True)
key value_x value_y _merge
0 A 1.764052 NaN left_only
1 B 0.400157 1.867558 both
2 C 0.978738 NaN left_only
3 D 2.240893 -0.977278 both
And similarly, for a RIGHT-Excluding JOIN,
(left.merge(right, on='key', how='right', indicator=True)
.query('_merge == "right_only"')
.drop('_merge', 1))
key value_x value_y
2 E NaN 0.950088
3 F NaN -0.151357
Lastly, if you are required to do a merge that only retains keys from the left or right, but not both (IOW, performing an ANTI-JOIN),
You can do this in similar fashion—
(left.merge(right, on='key', how='outer', indicator=True)
.query('_merge != "both"')
.drop('_merge', 1))
key value_x value_y
0 A 1.764052 NaN
2 C 0.978738 NaN
4 E NaN 0.950088
5 F NaN -0.151357
If the key columns are named differently—for example, left
has keyLeft
, and right
has keyRight
instead of key
—then you will have to specify left_on
and right_on
as arguments instead of on
:
left2 = left.rename({'key':'keyLeft'}, axis=1)
right2 = right.rename({'key':'keyRight'}, axis=1)
left2
keyLeft value
0 A 1.764052
1 B 0.400157
2 C 0.978738
3 D 2.240893
right2
keyRight value
0 B 1.867558
1 D -0.977278
2 E 0.950088
3 F -0.151357
left2.merge(right2, left_on='keyLeft', right_on='keyRight', how='inner')
keyLeft value_x keyRight value_y
0 B 0.400157 B 1.867558
1 D 2.240893 D -0.977278
When merging on keyLeft
from left
and keyRight
from right
, if you only want either of the keyLeft
or keyRight
(but not both) in the output, you can start by setting the index as a preliminary step.
left3 = left2.set_index('keyLeft')
left3.merge(right2, left_index=True, right_on='keyRight')
value_x keyRight value_y
0 0.400157 B 1.867558
1 2.240893 D -0.977278
Contrast this with the output of the command just before (that is, the output of left2.merge(right2, left_on='keyLeft', right_on='keyRight', how='inner')
), you'll notice keyLeft
is missing. You can figure out what column to keep based on which frame's index is set as the key. This may matter when, say, performing some OUTER JOIN operation.
DataFrames
For example, consider
right3 = right.assign(newcol=np.arange(len(right)))
right3
key value newcol
0 B 1.867558 0
1 D -0.977278 1
2 E 0.950088 2
3 F -0.151357 3
If you are required to merge only "new_val" (without any of the other columns), you can usually just subset columns before merging:
left.merge(right3[['key', 'newcol']], on='key')
key value newcol
0 B 0.400157 0
1 D 2.240893 1
If you're doing a LEFT OUTER JOIN, a more performant solution would involve map
:
# left['newcol'] = left['key'].map(right3.set_index('key')['newcol']))
left.assign(newcol=left['key'].map(right3.set_index('key')['newcol']))
key value newcol
0 A 1.764052 NaN
1 B 0.400157 0.0
2 C 0.978738 NaN
3 D 2.240893 1.0
As mentioned, this is similar to, but faster than
left.merge(right3[['key', 'newcol']], on='key', how='left')
key value newcol
0 A 1.764052 NaN
1 B 0.400157 0.0
2 C 0.978738 NaN
3 D 2.240893 1.0
To join on more than one column, specify a list for on
(or left_on
and right_on
, as appropriate).
left.merge(right, on=['key1', 'key2'] ...)
Or, in the event the names are different,
left.merge(right, left_on=['lkey1', 'lkey2'], right_on=['rkey1', 'rkey2'])
merge*
operations and functionsMerging a DataFrame with Series on index: See this answer.
Besides merge
, DataFrame.update
and DataFrame.combine_first
are also used in certain cases to update one DataFrame with another.
pd.merge_ordered
is a useful function for ordered JOINs.
pd.merge_asof
(read: merge_asOf) is useful for approximate joins.
This section only covers the very basics, and is designed to only whet your appetite. For more examples and cases, see the documentation on merge

I had a similar problem and I tried multiple solution. I solved it implementing 2 considerations.
dangerouslySetInnerHtml
to embed the <video>
code. For example:<div dangerouslySetInnerHTML={{ __html: `
<video class="video-js" playsinline autoplay loop muted>
<source src="../video_path.mp4" type="video/mp4"/>
</video>`}}
/>
Also, thanks to @boltcoder for his guide: Autoplay muted HTML5 video using React on mobile (Safari / iOS 10+)
To convert any JSON to array, use the below code:
const usersJson: any[] = Array.of(res.json());
Another approach in spark 2.1.0
is to use --conf spark.driver.userClassPathFirst=true
during spark-submit which changes the priority of dependency load, and thus the behavior of the spark-job, by giving priority to the jars the user is adding to the class-path with the --jars
option.
another reason this problem happens is when you call these methods with wrong indexes (indexes which there has NOT happened insert or remove in them)
-notifyItemRangeRemoved
-notifyItemRemoved
-notifyItemRangeInserted
-notifyItemInserted
check indexe parameters to these methods and make sure they are precise and correct.
Check out this solution. It worked for me..... Check the id of the button for which the error is raised...it may be the same in any one of the other page in your app. If yes, then change the id of them and then the app runs perfectly.
I was having two same button id's in two different XML codes....I changed the id. Now it runs perfectly!! Hope it works
Make sure the header files are publicly available as part of the framework's public headers.
Goto Framework -> Target -> Build Phases and drag to move the relevant header files from Project to Public. Hope that helps!
Using Accept header is really easy to get the format json or xml from the REST service.
This is my Controller, take a look produces section.
@RequestMapping(value = "properties", produces = {MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE}, method = RequestMethod.GET)
public UIProperty getProperties() {
return uiProperty;
}
In order to consume the REST service we can use the code below where header can be MediaType.APPLICATION_JSON_VALUE or MediaType.APPLICATION_XML_VALUE
HttpHeaders headers = new HttpHeaders();
headers.add("Accept", header);
HttpEntity entity = new HttpEntity(headers);
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8080/properties", HttpMethod.GET, entity,String.class);
return response.getBody();
Edit 01:
In order to work with application/xml
, add this dependency
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>

View.MeasureSpec.makeMeasureSpec(parent.getMeasuredHeight(), View.MeasureSpec.AT_MOST));
outRect.set(0, customView.getMeasuredHeight(), 0, 0);
} else {

}
}
}
May this one help a little more
Let suppose if you want to make the bar button in a separate file(for modular approach) and want to give selector back to your viewcontroller, you can do like this :-
your Utility File
class GeneralUtility {
class func customeNavigationBar(viewController: UIViewController,title:String){
let add = UIBarButtonItem(title: "Play", style: .plain, target: viewController, action: #selector(SuperViewController.buttonClicked(sender:)));
viewController.navigationController?.navigationBar.topItem?.rightBarButtonItems = [add];
}
}
Then make a SuperviewController class and define the same function on it.
class SuperViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
@objc func buttonClicked(sender: UIBarButtonItem) {
}
}
and In our base viewController(which inherit your SuperviewController class) override the same function
import UIKit
class HomeViewController: SuperViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func viewWillAppear(_ animated: Bool) {
GeneralUtility.customeNavigationBar(viewController: self,title:"Event");
}
@objc override func buttonClicked(sender: UIBarButtonItem) {
print("button clicked")
}
}
Now just inherit the SuperViewController in whichever class you want this barbutton.
Thanks for the read
If you don't mind a third party dependency, there is a class named Collectors2 in Eclipse Collections which contains methods returning Collectors for summing and summarizing BigDecimal and BigInteger. These methods take a Function as a parameter so you can extract a BigDecimal or BigInteger value from an object.
List<BigDecimal> list = mList(
BigDecimal.valueOf(0.1),
BigDecimal.valueOf(1.1),
BigDecimal.valueOf(2.1),
BigDecimal.valueOf(0.1));
BigDecimal sum =
list.stream().collect(Collectors2.summingBigDecimal(e -> e));
Assert.assertEquals(BigDecimal.valueOf(3.4), sum);
BigDecimalSummaryStatistics statistics =
list.stream().collect(Collectors2.summarizingBigDecimal(e -> e));
Assert.assertEquals(BigDecimal.valueOf(3.4), statistics.getSum());
Assert.assertEquals(BigDecimal.valueOf(0.1), statistics.getMin());
Assert.assertEquals(BigDecimal.valueOf(2.1), statistics.getMax());
Assert.assertEquals(BigDecimal.valueOf(0.85), statistics.getAverage());
Note: I am a committer for Eclipse Collections.
I've found that you can move div elements to the next line simply by setting the property
Display: block;
On each div.
Had the same issue here. I needed to bind to Youtube links. What worked for me, as a global solution, was to add the following to my config:
.config(['$routeProvider', '$sceDelegateProvider',
function ($routeProvider, $sceDelegateProvider) {
$sceDelegateProvider.resourceUrlWhitelist(['self', new RegExp('^(http[s]?):\/\/(w{3}.)?youtube\.com/.+$')]);
}]);
Adding 'self' in there is important - otherwise will fail to bind to any URL. From the angular docs
'self' - The special string, 'self', can be used to match against all URLs of the same domain as the application document using the same protocol.
With that in place, I'm now able to bind directly to any Youtube link.
You'll obviously have to customise the regex to your needs. Hope it helps!
Here is code that will upload multiple images at once, into a specific folder!
The HTML:
<form method="post" enctype="multipart/form-data" id="image_upload_form" action="submit_image.php">
<input type="file" name="images" id="images" multiple accept="image/x-png, image/gif, image/jpeg, image/jpg" />
<button type="submit" id="btn">Upload Files!</button>
</form>
<div id="response"></div>
<ul id="image-list">
</ul>
The PHP:
<?php
$errors = $_FILES["images"]["error"];
foreach ($errors as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$name = $_FILES["images"]["name"][$key];
//$ext = pathinfo($name, PATHINFO_EXTENSION);
$name = explode("_", $name);
$imagename='';
foreach($name as $letter){
$imagename .= $letter;
}
move_uploaded_file( $_FILES["images"]["tmp_name"][$key], "images/uploads/" . $imagename);
}
}
echo "<h2>Successfully Uploaded Images</h2>";
And finally, the JavaSCript/Ajax:
(function () {
var input = document.getElementById("images"),
formdata = false;
function showUploadedItem (source) {
var list = document.getElementById("image-list"),
li = document.createElement("li"),
img = document.createElement("img");
img.src = source;
li.appendChild(img);
list.appendChild(li);
}
if (window.FormData) {
formdata = new FormData();
document.getElementById("btn").style.display = "none";
}
input.addEventListener("change", function (evt) {
document.getElementById("response").innerHTML = "Uploading . . ."
var i = 0, len = this.files.length, img, reader, file;
for ( ; i < len; i++ ) {
file = this.files[i];
if (!!file.type.match(/image.*/)) {
if ( window.FileReader ) {
reader = new FileReader();
reader.onloadend = function (e) {
showUploadedItem(e.target.result, file.fileName);
};
reader.readAsDataURL(file);
}
if (formdata) {
formdata.append("images[]", file);
}
}
}
if (formdata) {
$.ajax({
url: "submit_image.php",
type: "POST",
data: formdata,
processData: false,
contentType: false,
success: function (res) {
document.getElementById("response").innerHTML = res;
}
});
}
}, false);
}());
Hope this helps

I don't know if this will help anyone or not but as I was facing the same issue I thought of sharing how I got the solution.
You can use track by attribute in your ng-options
.
Assume that you have:
variants:[{'id':0, name:'set of 6 traits'}, {'id':1, name:'5 complete sets'}]
You can mention your ng-options
as:
ng-options="v.name for v in variants track by v.id"
Hope this helps someone in future.
Here is the swift version (by using @Nitesh Borad objective C code) :-
if let img: UIImage = UIImage(data: previewImg[indexPath.row]) {
cell.cardPreview.image = img
} else {
// The image isn't cached, download the img data
// We should perform this in a background thread
let imgURL = NSURL(string: "webLink URL")
let request: NSURLRequest = NSURLRequest(URL: imgURL!)
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
let error = error
let data = data
if error == nil {
// Convert the downloaded data in to a UIImage object
let image = UIImage(data: data!)
// Store the image in to our cache
self.previewImg[indexPath.row] = data!
// Update the cell
dispatch_async(dispatch_get_main_queue(), {
if let cell: YourTableViewCell = tableView.cellForRowAtIndexPath(indexPath) as? YourTableViewCell {
cell.cardPreview.image = image
}
})
} else {
cell.cardPreview.image = UIImage(named: "defaultImage")
}
})
task.resume()
}
Try this
function add_post($post_data){
$this->db->insert('posts', $post_data);
$insert_id = $this->db->insert_id();
return $insert_id;
}
In case of multiple inserts you could use
$this->db->trans_start();
$this->db->trans_complete();
<div style="height: 100px;"> </div>
OR
<div id="foo"/> and set the style as #foo { height: 100px; }
<div class="bar"/> and set the style as .bar{ height: 100px; }
One way to print your code is to push it to an online version control system like Github or Bitbucket. In your browser, navigate to the file and print it.
Doing it this way, you'll get syntax highlighting and version control.
Keeping it simple, if you want the request to use the same browsing context as the page you are already looking at then in the Chrome console just do:
window.location="https://www.example.com";
I got same problem trying to compile "clean install" using a Lowend 512Mb ram VPS and good CPU. Run OutOfMemory and killed script repeatly.
I used export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=350m"
and worked.
Still getting some other compiling failure because is the first time i need Maven, but OutOfMemory problem has gone.
You can use JavaScript like... Just give the proper path of your json file...
<!doctype html>
<html>
<head>
<script type="text/javascript" src="abc.json"></script>
<script type="text/javascript" >
function load() {
var mydata = JSON.parse(data);
alert(mydata.length);
var div = document.getElementById('data');
for(var i = 0;i < mydata.length; i++)
{
div.innerHTML = div.innerHTML + "<p class='inner' id="+i+">"+ mydata[i].name +"</p>" + "<br>";
}
}
</script>
</head>
<body onload="load()">
<div id="data">
</div>
</body>
</html>
Simply getting the data and appending it to a div... Initially printing the length in alert.
Here is my Json file: abc.json
data = '[{"name" : "Riyaz"},{"name" : "Javed"},{"name" : "Arun"},{"name" : "Sunil"},{"name" : "Rahul"},{"name" : "Anita"}]';
Add Content-Type: application/json
and Accept: application/json
in REST Client header section
assylias and Head of Catering have already given your the reason why the error is occurring.
Now regarding what you are doing, from what I understand, you don't need to use Select
at all
I guess you are doing this from VBA PowerPoint? If yes, then your code be rewritten as
Dim sourceXL As Object, sourceBook As Object
Dim sourceSheet As Object, sourceSheetSum As Object
Dim lRow As Long
Dim measName As Variant, partName As Variant
Dim filepath As String
filepath = CStr(FileDialog)
'~~> Establish an EXCEL application object
On Error Resume Next
Set sourceXL = GetObject(, "Excel.Application")
'~~> If not found then create new instance
If Err.Number <> 0 Then
Set sourceXL = CreateObject("Excel.Application")
End If
Err.Clear
On Error GoTo 0
Set sourceBook = sourceXL.Workbooks.Open(filepath)
Set sourceSheet = sourceBook.Sheets("Measurements")
Set sourceSheetSum = sourceBook.Sheets("Analysis Summary")
lRow = sourceSheetSum.Range("C" & sourceSheetSum.Rows.Count).End(xlUp).Row
measName = sourceSheetSum.Range("C3:C" & lRow)
lRow = sourceSheetSum.Range("D" & sourceSheetSum.Rows.Count).End(xlUp).Row
partName = sourceSheetSum.Range("D3:D" & lRow)
I was playing around with this and tried all solutions, eventually the solution I went with was a suggestion from Google Chrome's Inspector. If you add this to your CSS it worked for me:
video{
object-fit: inherit;
}
This is caused by the limited support for the MP4 format within the video tag in Firefox. Support was not added until Firefox 21, and it is still limited to Windows 7 and above. The main reason for the limited support revolves around the royalty fee attached to the mp4 format.
Check out Supported media formats and Media formats supported by the audio and video elements directly from the Mozilla crew or the following blog post for more information:

by testing against a set of test patterns to make sure that is a valid syntax and does what you intend with a fully range of test URIs.
See regexpCheck.php below for a simple script that you can add to a private/test directory in your site to help you do this. I've kept this brief rather than pretty. Just past this into a file regexpCheck.php
in a test directory to use it on your website. This will help you build up any regexp and test it against a list of test cases as you do so. I am using the PHP PCRE engine here, but having had a look at the Apache source, this is basically identical to the one used in Apache. There are many HowTos and tutorials which provide templates and can help you build your regexp skills.

The cleanest solution - also purely CSS - would be using calc and vh.
The middle div's heigh will be calculated thusly:
#middle-div {
height: calc(100vh - 46px);
}
That is, 100% of the viewport height minus the 2*23px. This will ensure that the page loads properly and is dynamic(demo here).
Also remember to use box-sizing, so the paddings and borders don't make the divs outfill the viewport.
When trying to remove gems installed as root, xargs seems to halt when it encounters an error trying to uninstall a default gem:
sudo gem list | cut -d" " -f1 | xargs gem uninstall -aIx
# ERROR: While executing gem ... (Gem::InstallError)
# gem "test-unit" cannot be uninstalled because it is a default gem
This won't work for everyone, but here's what I used instead:
sudo for gem (`gem list | cut -d" " -f1`); do gem uninstall $gem -aIx; done
Uninstallation :
sudo /Library/PostgreSQL/9.6/uninstall-postgresql.app/Contents/MacOS/installbuilder.sh
Removing the data file :
sudo rm -rf /Library/PostgreSQL
Removing the configs :
sudo rm /etc/postgres-reg.ini
And thats it.
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)).
1.Set the following Environment Property on your active Shell. - open bash terminal and type in:
$ export LD_BIND_NOW=1
Note: for superuser in bash type su and press enter
For curl
, how about using the -d
switch? Like: curl -X PUT "localhost:8080/urlstuffhere" -d "@filename"
?
If you give generally give a span
the property display:block
, it'll then behave like a div
, i.e you can set width and height.
You can also skip the div
or span
and just set the a
the to display: block
and apply the backgound style to it.
<a href="" class="myImage"><!----></a>
<style>
.myImage {display: block; width: 160px; height: 20px; margin:0 0 10px 0; background: url(image.png) center top no-repeat;}
.myImage:hover{background-image(image_hover.png);}
</style>
Of all the answers, none considered the ridiculously easy fastcgi_finish_request function, that when called, flushes all remaining output to the browser and closes the Fastcgi session and the HTTP connection, while letting the script run in the background.
An example:
<?php
header('Content-Type: application/json');
echo json_encode(['ok' => true]);
fastcgi_finish_request(); // The user is now disconnected from the script
// do stuff with received data,
I know this is an very old question, but have you tried the hardwareAccelerated="true"
manifest flag for your application or activity?
With this set, it seems to work without any WebChromeClient modification (which I would expect from an DOM-Element.)
Here is a link to the data URI method Mathew suggested, it worked on safari, but not well because I couldn't set the filetype, it gets saved as "unknown" and then i have to go there again later and change it in order to view the file...
Incidentally, .ogv files are video, so "video/ogg", .ogg files are Vorbis audio, so "audio/ogg" and .oga files are general Ogg audio, so also "audio/ogg". Checked in Firefox and work. "application/ogg" is deprecated for all audio or video uses. See http://www.rfc-editor.org/rfc/rfc5334.txt

I think there is a version for IE and also with Explorer Integration. Pretty good software.
I'm facing a similar problem. I'm using Query by Example and I want to sort the results by a custom field. In SQL I would do something like:
select pageNo, abs(pageNo - 434) as diff
from relA
where year = 2009
order by diff
It works fine without the order-by-clause. What I got is
Criteria crit = getSession().createCriteria(Entity.class);
crit.add(exampleObject);
ProjectionList pl = Projections.projectionList();
pl.add( Projections.property("id") );
pl.add(Projections.sqlProjection("abs(`pageNo`-"+pageNo+") as diff", new String[] {"diff"}, types ));
crit.setProjection(pl);
But when I add
crit.addOrder(Order.asc("diff"));
I get a org.hibernate.QueryException: could not resolve property: diff exception. Workaround with this does not work either.
PS: as I could not find any elaborate documentation on the use of QBE for Hibernate, all the stuff above is mainly trial-and-error approach
Recently we had a similar problem and had to solve it in a different way. We had to merge two branches up to two commits, which were not the heads of either branches:
branch A: A1 -> A2 -> A3 -> A4
branch B: B1 -> B2 -> B3 -> B4
branch C: C1 -> A2 -> B3 -> C2
For example, we had to merge branch A up to A2 and branch B up to B3. But branch C had cherry-picks from A and B. When using the SHA of A2 and B3 it looked like there was confusion because of the local branch C which had the same SHA.
To avoid any kind of ambiguity we removed branch C locally, and then created a branch AA starting from commit A2:
git co A
git co SHA-of-A2
git co -b AA
Then we created a branch BB from commit B3:
git co B
git co SHA-of-B3
git co -b BB
At that point we merged the two branches AA and BB. By removing branch C and then referencing the branches instead of the commits it worked.
It's not clear to me how much of this was superstition or what actually made it work, but this "long approach" may be helpful.
There are two typical ways of declaring a function. I prefer the second approach.
function function_name {
command...
}
or
function_name () {
command...
}
To call a function with arguments:
function_name "$arg1" "$arg2"
The function refers to passed arguments by their position (not by name), that is $1
, $2
, and so forth. $0
is the name of the script itself.
Example:
function_name () {
echo "Parameter #1 is $1"
}
Also, you need to call your function after it is declared.
#!/usr/bin/env sh
foo 1 # this will fail because foo has not been declared yet.
foo() {
echo "Parameter #1 is $1"
}
foo 2 # this will work.
Output:
./myScript.sh: line 2: foo: command not found
Parameter #1 is 2
Tries to use negative padding
Like:
android:paddingLeft="-8dp"
You can try setting the word-wrap
however it doesn't work in all browsers yet.
Another method would be to add an element around your cell data like this:
<td><span>...</span></td>
Then add some css like this:
.datatable td span{
max-width: 400px;
display: block;
overflow: hidden;
}
Below is a Swift Playground example:
import UIKit
let jsonString = "{\"name\": \"John Doe\", \"phone\":123456}"
let data = jsonString.data(using: .utf8)
var jsonObject: Any
do {
jsonObject = try JSONSerialization.jsonObject(with: data!) as Any
if let obj = jsonObject as? NSDictionary {
print(obj["name"])
}
} catch {
print("error")
}
ENV PYTHONWARNINGS="ignore::DeprecationWarning"
int a = srand(time(NULL))
arr[i] = a;
Should be
arr[i] = rand();
And put srand(time(NULL))
somewhere at the very beginning of your program.
I had this issue when I was running two projects that had the same set up and I already had one running. This meant that the other project couldn't use that port number. As soon as I stopped the other project running I had no issues.
brew switch libfoo mycopy
You can use brew switch
to switch between versions of the same package, if it's installed as versioned subdirectories under Cellar/<packagename>/
This will list versions installed ( for example I had Cellar/sdl2/2.0.3
, I've compiled into Cellar/sdl2/2.0.4
)
brew info sdl2
Then to switch between them
brew switch sdl2 2.0.4
brew info
Info now shows *
next to the 2.0.4
To install under Cellar/<packagename>/<version>
from source you can do for example
cd ~/somewhere/src/foo-2.0.4
./configure --prefix $(brew --Cellar)/foo/2.0.4
make
check where it gets installed with
make install -n
if all looks correct
make install
Then from cd $(brew --Cellar)
do the switch between version.
I'm using brew version 0.9.5
Why not try this.
NSArray *animationFrames = [NSArray arrayWithObjects:
[UIImage imageWithName:@"image1.png"],
[UIImage imageWithName:@"image2.png"],
nil];
UIImageView *animatedImageView = [[UIImageView alloc] init];
animatedImageView.animationImages = animationsFrame;
[animatedImageView setAnimationRepeatCount:1];
[animatedImageView startAnimating];
A swift version:
let animationsFrames = [UIImage(named: "image1.png"), UIImage(named: "image2.png")]
let animatedImageView = UIImageView()
animatedImageView.animationImages = animationsFrames
animatedImageView.animationRepeatCount = 1
animatedImageView.startAnimating()
Actually an easier way to fix this is to move the #import
statement to the top of the .m
file instead (instead of having it in your .h
header file). This way it won't complain that it's including a non-modular header file. I had this problem where Allow non-module includes
set to YES
did NOT work for me, so by moving it to the implementation file, it stopped complaining. This is in fact the preferred way of importing and including header files anyway. Once you've done this, setting this back to NO
should work.
Ideally we should try and aim to have Allow non-module includes
set to NO
. Setting this to YES
in most cases means you're doing something wrong. The setting translates to "Allow importing random header files on disk that aren't otherwise part of the module". This applies to a very few use cases in practice, and so this setting should always be NO
(i.e. the default value).
Try this: http://jsbin.com/axaler/3/edit
$(function(){
$(window).scroll(function(){
var aTop = $('.ad').height();
if($(this).scrollTop()>=aTop){
alert('header just passed.');
// instead of alert you can use to show your ad
// something like $('#footAd').slideup();
}
});
});
The W3C solution:
var len = document.getElementById("input1").length;
We've had similar problem and it was not enough to only remove commit and force push to GitLab.
It was still available in GitLab interface using url:
https://gitlab.example.com/<group>/<project>/commit/<commit hash>
We've had to remove project from GitLab and recreate it to get rid of this commit in GitLab UI.
Creating a virtual environment for Jupyter Notebooks
A minimal Python install is
sudo apt install python3.7 python3.7-venv python3.7-minimal python3.7-distutils python3.7-dev python3.7-gdbm python3-gdbm-dbg python3-pip
Then you can create and use the environment
/usr/bin/python3.7 -m venv test
cd test
source test/bin/activate
pip install jupyter matplotlib seaborn numpy pandas scipy
# install other packages you need with pip/apt
jupyter notebook
deactivate
You can make a kernel for Jupyter with
ipython3 kernel install --user --name=test
This is simpler in my head than anywhere here, so:
401: You need HTTP basic auth to see this.
403: You can't see this, and HTTP basic auth won't help.
If the user just needs to log in using you site's standard HTML login form, 401 would not be appropriate because it is specific to HTTP basic auth.
I don't recommend using 403 to deny access to things like /includes
, because as far as the web is concerned, those resources don't exist at all and should therefore 404.
This leaves 403 as "you need to be logged in".
In other words, 403 means "this resource requires some form of auth other than HTTP basic auth".

Either way will add an entity to a PersistenceContext, the difference is in what you do with the entity afterwards.
Persist takes an entity instance, adds it to the context and makes that instance managed (ie future updates to the entity will be tracked).
Merge returns the managed instance that the state was merged to. It does return something what exists in PersistenceContext or creates a new instance of your entity. In any case, it will copy the state from the supplied entity, and return managed copy. The instance you pass in will not be managed (any changes you make will not be part of the transaction - unless you call merge again). Though you can use the returned instance (managed one).
Maybe a code example will help.
MyEntity e = new MyEntity();
// scenario 1
// tran starts
em.persist(e);
e.setSomeField(someValue);
// tran ends, and the row for someField is updated in the database
// scenario 2
// tran starts
e = new MyEntity();
em.merge(e);
e.setSomeField(anotherValue);
// tran ends but the row for someField is not updated in the database
// (you made the changes *after* merging)
// scenario 3
// tran starts
e = new MyEntity();
MyEntity e2 = em.merge(e);
e2.setSomeField(anotherValue);
// tran ends and the row for someField is updated
// (the changes were made to e2, not e)
Scenario 1 and 3 are roughly equivalent, but there are some situations where you'd want to use Scenario 2.
For Python3 the following code grabs the word list from the web and returns a list. Answer based on accepted answer above by Kyle Kelley.
import urllib.request
word_url = "http://svnweb.freebsd.org/csrg/share/dict/words?view=co&content-type=text/plain"
response = urllib.request.urlopen(word_url)
long_txt = response.read().decode()
words = long_txt.splitlines()
Output:
>>> words
['a', 'AAA', 'AAAS', 'aardvark', 'Aarhus', 'Aaron', 'ABA', 'Ababa',
'aback', 'abacus', 'abalone', 'abandon', 'abase', 'abash', 'abate',
'abbas', 'abbe', 'abbey', 'abbot', 'Abbott', 'abbreviate', ... ]
And to generate (because it was my objective) a list of 1) upper case only words, 2) only "name like" words, and 3) a sort-of-realistic-but-fun sounding random name:
import random
upper_words = [word for word in words if word[0].isupper()]
name_words = [word for word in upper_words if not word.isupper()]
rand_name = ' '.join([name_words[random.randint(0, len(name_words))] for i in range(2)])
And some random names:
>>> for n in range(10):
' '.join([name_words[random.randint(0,len(name_words))] for i in range(2)])
'Semiramis Sicilian'
'Julius Genevieve'
'Rwanda Cohn'
'Quito Sutherland'
'Eocene Wheller'
'Olav Jove'
'Weldon Pappas'
'Vienna Leyden'
'Io Dave'
'Schwartz Stromberg'
It turns out there is a special case where this can be achieved. The trick is when building the DataTable, collect all the rows in a list, sort them, then add them. This case just came up here.
{{ wpis.entry.lastChangeDate|date:"SHORT_DATETIME_FORMAT" }}
Why not just use rm -rf __pycache__

Here's another alternative if, for any reason, you can't or don't want to use HttpUtility.ParseQueryString()
.
This is built to be somewhat tolerant to "malformed" query strings, i.e. http://test/test.html?empty=
becomes a parameter with an empty value. The caller can verify the parameters if needed.
public static class UriHelper
{
public static Dictionary<string, string> DecodeQueryParameters(this Uri uri)
{
if (uri == null)
throw new ArgumentNullException("uri");
if (uri.Query.Length == 0)
return new Dictionary<string, string>();
return uri.Query.TrimStart('?')
.Split(new[] { '&', ';' }, StringSplitOptions.RemoveEmptyEntries)
.Select(parameter => parameter.Split(new[] { '=' }, StringSplitOptions.RemoveEmptyEntries))
.GroupBy(parts => parts[0],
parts => parts.Length > 2 ? string.Join("=", parts, 1, parts.Length - 1) : (parts.Length > 1 ? parts[1] : ""))
.ToDictionary(grouping => grouping.Key,
grouping => string.Join(",", grouping));
}
}

The result stated above may be correct, but isn't working with the latest webdriver. Here is my solution for the above question. Simple and sweet
http_proxy = "ip_addr:port"
https_proxy = "ip_addr:port"
webdriver.DesiredCapabilities.FIREFOX['proxy']={
"httpProxy":http_proxy,
"sslProxy":https_proxy,
"proxyType":"MANUAL"
}
driver = webdriver.Firefox()
OR
http_proxy = "http://ip:port"
https_proxy = "https://ip:port"
proxyDict = {
"http" : http_proxy,
"https" : https_proxy,
}
driver = webdriver.Firefox(proxy=proxyDict)
What is your output when you do java -version
? This will tell you what version the running JVM is.
The Unsupported major.minor version 51.0 error could mean:
Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor
error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)
See: http://www.java.com/en/download/manual.jsp (7 Update 25 )
and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)
for the latest version of the JRE and JDK respectively.
EDIT:
Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.
Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.
Also, you could use regex findall. It's a more general solution since it adds more control over the length of the number. It could be helpful in cases where you require a number with minimal length.
True if len(''.join(re.findall('\d+', '67389kjsdk'))) > 0 else False
Hope it helps some else.
You can use the DataGridView refresh method. But... in a lot of cases you have to refresh the DataGridView from methods running on a different thread than the one where the DataGridView is running. In order to do that you should implement the following method and call it rather than directly typing DataGridView.Refresh():
private void RefreshGridView()
{
if (dataGridView1.InvokeRequired)
{
dataGridView1.Invoke((MethodInvoker)delegate ()
{
RefreshGridView();
});
}
else
dataGridView1.Refresh();
}
In the special case: "All elements of List1 goes to a new List2": (e.g. a string list)
List<string> list2 = new List<string>(list1);
In this case, list2 is generated with all elements from list1.
I know this is an old question but I thought I'd still share my method of adding image captions. You won't be able to use the caption
or figcaption
tags, but this would be a simple alternative without using any plugins.
In your markdown, you can wrap your caption with the emphasis tag and put it directly underneath the image without inserting a new line like so:
![](path_to_image)
*image_caption*
This would generate the following HTML:
<p>
<img src="path_to_image" alt>
<em>image_caption</em>
</p>
Then in your CSS you can style it using the following selector without interfering with other em
tags on the page:
img + em { }
Note that you must not have a blank line between the image and the caption because that would instead generate:
<p>
<img src="path_to_image" alt>
</p>
<p>
<em>image_caption</em>
</p>
You can also use whatever tag you want other than em
. Just make sure there is a tag, otherwise you won't be able to style it.
You can use this method to log the exception stack to String
public String stackTraceToString(Throwable e) {
StringBuilder sb = new StringBuilder();
for (StackTraceElement element : e.getStackTrace()) {
sb.append(element.toString());
sb.append("\n");
}
return sb.toString();

Usualy, your code should work...
But here is a way to center text in css:
.text
{
margin-left: auto;
margin-right: auto;
}
This has proved to be bulletproof to me whenever I want to center text with css.
Replaced the reader declaration with this one and now it works!
Dim reader As New StreamReader(filetoimport.Text, Encoding.Default)
Encoding.Default represents the ANSI code page that is set under Windows Control Panel.
Have you looked into using a HorizontalScrollView to wrap your list items? That will allow each of your list items to be horizontally scrollable (what you put in there is up to you, and can make them dynamic items similar to ListView). This will work well if you are only after a single row of items.
If you comment out the following code from the _Layout.cshtml
page, the modal popup will start working:
</footer>
@*@Scripts.Render("~/bundles/jquery")*@
@RenderSection("scripts", required: false)
</body>
</html>
I had a similar issue when using AD on CAS , i.e. 52e error, In my case application accepts the Full Name when in the form of CN= instead of the actual username.
For example, if you had a user who's full name is Ross Butler and their login username is rbutler --you would normally put something like, cn=rbutler,ou=Users,dc=domain,dc=com but ours failed everytime. By changing this to cn=Ross Butler,ou=Users,dc=domain,dc=com it passed!!
You can use re.finditer()
for non-overlapping matches.
>>> import re
>>> aString = 'this is a string where the substring "is" is repeated several times'
>>> print [(a.start(), a.end()) for a in list(re.finditer('is', aString))]
[(2, 4), (5, 7), (38, 40), (42, 44)]
but won't work for:
In [1]: aString="ababa"
In [2]: print [(a.start(), a.end()) for a in list(re.finditer('aba', aString))]
Output: [(0, 3)]
I think the second one should be

select t).OrderByDescending(c => c.Delivery.SubmissionDate);
I was looking around for an answer on bulk inserting Objects.
The answer by Ragnar123 led me to making this function:

You can disable all debugging logs using os.environ
:
import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'
import tensorflow as tf
Tested on tf 0.12 and 1.0
In details,
0 = all messages are logged (default behavior)
1 = INFO messages are not printed
2 = INFO and WARNING messages are not printed
3 = INFO, WARNING, and ERROR messages are not printed
According to OpenCV cheat-sheet this can be done as follows:
IplImage* oldC0 = cvCreateImage(cvSize(320,240),16,1);
Mat newC = cvarrToMat(oldC0);
The cv::cvarrToMat function takes care of the conversion issues.
I'd like to throw in the whoami command, which basically is a nice alias for doing %USERDOMAIN%\%USERNAME%
as proposed in other answers.
Write-Host "current user:"
Write-Host $(whoami)
Turn on debug logging to get a better picture of what is going on.
You can tell if the session cookies are being set by using a browser-side debugger to look at the headers returned in HTTP responses. (There are other ways too.)
One possibility is that SpringSecurity is setting secure session cookies, and your next page requested has an "http" URL instead of an "https" URL. (The browser won't send a secure cookie for an "http" URL.)
A cookie is basically just an item in a dictionary. Each item has a key and a value. For authentication, the key could be something like 'username' and the value would be the username. Each time you make a request to a website, your browser will include the cookies in the request, and the host server will check the cookies. So authentication can be done automatically like that.
To set a cookie, you just have to add it to the response the server sends back after requests. The browser will then add the cookie upon receiving the response.
There are different options you can configure for the cookie server side, like expiration times or encryption. An encrypted cookie is often referred to as a signed cookie. Basically the server encrypts the key and value in the dictionary item, so only the server can make use of the information. So then cookie would be secure.
A browser will save the cookies set by the server. In the HTTP header of every request the browser makes to that server, it will add the cookies. It will only add cookies for the domains that set them. Example.com can set a cookie and also add options in the HTTP header for the browsers to send the cookie back to subdomains, like sub.example.com. It would be unacceptable for a browser to ever sends cookies to a different domain.
Most Git repositories use master
as the main (and default) branch - if you initialize a new Git repo via git init
, it will have master
checked out by default.
However, if you clone a repository, the default branch you have is whatever the remote's HEAD
points to (HEAD
is actually a symbolic ref that points to a branch name). So if the repository you cloned had a HEAD
pointed to, say, foo
, then your clone will just have a foo
branch.
The remote you cloned from might still have a master
branch (you could check with git ls-remote origin master
), but you wouldn't have created a local version of that branch by default, because git clone
only checks out the remote's HEAD
.
On many devices (such as the iPhone), it prevents the user from using the browser's zoom. If you have a map and the browser does the zooming, then the user will see a big ol' pixelated image with huge pixelated labels. The idea is that the user should use the zooming provided by Google Maps. Not sure about any interaction with your plugin, but that's what it's there for.
More recently, as @ehfeng notes in his answer, Chrome for Android (and perhaps others) have taken advantage of the fact that there's no native browser zooming on pages with a viewport tag set like that. This allows them to get rid of the dreaded 300ms delay on touch events that the browser takes to wait and see if your single touch will end up being a double touch. (Think "single click" and "double click".) However, when this question was originally asked (in 2011), this wasn't true in any mobile browser. It's just added awesomeness that fortuitously arose more recently.

If you're using display:table-row
etc., then you need proper markup, which includes a containing table. Without it your original question basically provides the equivalent bad markup of:
<tr style="width:100%">
<td>Type</td>
<td style="float:right">Name</td>
</tr>
Where's the table in the above? You can't just have a row out of nowhere (tr must be contained in either table
, thead
, tbody
, etc.)
Instead, add an outer element with display:table
, put the 100% width on the containing element. The two inside cells will automatically go 50/50 and align the text right on the second cell. Forget floats
with table elements. It'll cause so many headaches.
markup:
<div class="view-table">
<div class="view-row">
<div class="view-type">Type</div>
<div class="view-name">Name</div>
</div>
</div>
CSS:
.view-table
{
display:table;
width:100%;
}
.view-row,
{
display:table-row;
}
.view-row > div
{
display: table-cell;
}
.view-name
{
text-align:right;
}
If you are interested in the indexes, the best choice is np.argsort(a)
a = np.random.randint(0, 100, 10)
sorted_idx = np.argsort(a)

System.out.println("Done reading the file.");
}

System.err.println("An error occured:" + exc.getMessage());
}
}
);
System.out.println("This thread keeps on running");
Thread.sleep(100);
}
Highlight the cell(s)/column which you want as Duration, right click on the mouse to "Format Cells". Go to "Custom" and look for "h:mm" if you want to input duration in hour and minutes format. If you want to include seconds as well, click on "h:mm:ss". You can even add up the total duration after that.
Hope this helps.
Your Customer
class has to be discovered by CDI as a bean. For that you have two options:
Put a bean defining annotation on it. As @Model
is a stereotype it's why it does the trick. A qualifier like @Named
is not a bean defining annotation, reason why it doesn't work
Change the bean discovery mode in your bean archive from the default "annotated" to "all" by adding a beans.xml
file in your jar.
Keep in mind that @Named has only one usage : expose your bean to the UI. Other usages are for bad practice or compatibility with legacy framework.
My problem was, as it was mentioned by copeland3300, that my script is running from notepad++ folder, so it was impossible to locate other project files, such as database file, modules etc. I solved the problem using standard notepad++ "Run" command (F5) and typing in:
cmd /k "cd /d "$(CURRENT_DIRECTORY)" & python "$(FULL_CURRENT_PATH)""
Python WAS in my PATH. Cmd window stayed open after script finished.
If you need support for all standardized named character references, unicode and ambiguous ampersands, the he library is the only 100% reliable solution I'm aware of!
he.encode('foo © bar ? baz qux');
// Output : 'foo © bar ≠ baz 𝌆 qux'
he.decode('foo © bar ≠ baz 𝌆 qux');
// Output : 'foo © bar ? baz qux'
Just use the length
property of a JavaScript
array like so:
$scope.names.length
Also, I don't see a starting <script>
tag in your code.
If you want the length inside your view, do it like so:
{{ names.length }}

If you're registering a domain and the termination (ex .com
) it is not IDN, as Aaron Hathaway said:
Hostnames are composed of series of labels concatenated with dots, as are all domain names. For example, en.wikipedia.org
is a hostname. Each label must be between 1 and 63 characters long, and the entire hostname (including the delimiting dots but not a trailing dot) has a maximum of 253 ASCII characters.
The Internet standards (Requests for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters a
through z
(in a case-insensitive manner), the digits 0
through 9
, and the hyphen -
. The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or white space are permitted.
Later, Spain with it's .es
, .com.es
, .org.es
, .nom,es
, .gob.es
and .edu.es
introduced IDN tlds, if your tld is one of .es
or any other that supports it, any character can be used, but you can't combine alphabets like Latin, Greek or Cyril in one hostname, and that it respects the things that can't go at the start or at the end.
If you're using non-registered tlds, just for local networking, like with local DNS or with hosts files, you can treat them all as IDN.
Keep in mind some programs could not work well, especially old, outdated and unpopular ones.
Are u sure u want to remove only last character. What if the user press backspace from the middle of the word.. Its better to get the value from the field and replace the divs html. On keyup
$("#div").html($("#input").val());
Why not do it?
var result= ctx.table.Where(x => x.UserName == "Value").FirstOrDefault();
if(result?.field == value)
{
// Match!
}
Try the heredoc-based solution:
echo <<<HTML
<div>
<h3><a href="#">First</a></h3>
<div>Lorem ipsum dolor sit amet.</div>
</div>
<div>
HTML;
You're not working with strings. You're working with pointers.
var1
is a char pointer (const char*
). It is not a string. If it is null-terminated, then certain C functions will treat it as a string, but it is fundamentally just a pointer.
So when you compare it to a char array, the array decays to a pointer as well, and the compiler then tries to find an operator == (const char*, const char*)
.
Such an operator does exist. It takes two pointers and returns true
if they point to the same address. So the compiler invokes that, and your code breaks.
IF you want to do string comparisons, you have to tell the compiler that you want to deal with strings, not pointers.
The C way of doing this is to use the strcmp
function:
strcmp(var1, "dev");
This will return zero if the two strings are equal. (It will return a value greater than zero if the left-hand side is lexicographically greater than the right hand side, and a value less than zero otherwise.)
So to compare for equality you need to do one of these:
if (!strcmp(var1, "dev")){...}
if (strcmp(var1, "dev") == 0) {...}
However, C++ has a very useful string
class. If we use that your code becomes a fair bit simpler. Of course we could create strings from both arguments, but we only need to do it with one of them:
std::string var1 = getenv("myEnvVar");
if(var1 == "dev")
{
// do stuff
}
Now the compiler encounters a comparison between string and char pointer. It can handle that, because a char pointer can be implicitly converted to a string, yielding a string/string comparison. And those behave exactly as you'd expect.
If you want the word "Hello" to print in a column that's 40 characters wide, with spaces padding the left, use the following.
char *ptr = "Hello";
printf("%40s\n", ptr);
That will give you 35 spaces, then the word "Hello". This is how you format stuff when you know how wide you want the column, but the data changes (well, it's one way you can do it).
If you know you want exactly 40 spaces then some text, just save the 40 spaces in a constant and print them. If you need to print multiple lines, either use multiple printf
statements like the one above, or do it in a loop, changing the value of ptr
each time.
ieshims.dll
is an artefact of Vista/7 where a shim DLL is used to proxy certain calls (such as CreateProcess
) to handle protected mode IE, which doesn't exist on XP, so it is unnecessary. wer.dll
is related to Windows Error Reporting and again is probably unused on Windows XP which has a slightly different error reporting system than Vista and above.
I would say you shouldn't need either of them to be present on XP and would normally be delay loaded anyway.
Simply use
$(document).height() // - $('body').offset().top
and / or
$(window).height()
instead of $('body').height();
You need to choose one of the following solutions:
A common solution is to make a base view model which contains the properties used in the layout file and then inherit from the base model to the models used on respective pages.
The problem with this approach is that you now have locked yourself into the problem of a model can only inherit from one other class, and maybe your solution is such that you cannot use inheritance on the model you intended anyways.
My solution also starts of with a base view model:
public class LayoutModel
{
public LayoutModel(string title)
{
Title = title;
}
public string Title { get;}
}
What I then use is a generic version of the LayoutModel which inherits from the LayoutModel, like this:
public class LayoutModel<T> : LayoutModel
{
public LayoutModel(T pageModel, string title) : base(title)
{
PageModel = pageModel;
}
public T PageModel { get; }
}
With this solution I have disconnected the need of having inheritance between the layout model and the model.
So now I can go ahead and use the LayoutModel in Layout.cshtml like this:
@model LayoutModel
<!doctype html>
<html>
<head>
<title>@Model.Title</title>
</head>
<body>
@RenderBody()
</body>
</html>
And on a page you can use the generic LayoutModel like this:
@model LayoutModel<Customer>
@{
var customer = Model.PageModel;
}
<p>Customer name: @customer.Name</p>
From your controller you simply return a model of type LayoutModel:
public ActionResult Page()
{
return View(new LayoutModel<Customer>(new Customer() { Name = "Test" }, "Title");
}
When we create a new RDS DB instance, the default master user is not the root user. But only gets certain privileges for that DB instance. This permission does not include SET permission. Now if your default master user tries to execute mysql SET commands, then you will face this error: Access denied; you need (at least one of) the SUPER or SYSTEM_VARIABLES_ADMIN privilege(s) for this operation
Comment out or remove these lines
SET @MYSQLDUMP_TEMP_LOG_BIN = @@SESSION.SQL_LOG_BIN;
SET @@SESSION.SQL_LOG_BIN= 1;
SET @@GLOBAL.GTID_PURGED=/*!80000 '+'*/ '';
You can also ignore the errors by using the -f option to load the rest of the dump file.
mysql -f <REPLACE_DB_NAME> -u <REPLACE_DB_USER> -h <DB_HOST_HERE> -p < dumpfile.sql
Now I use Dojo Toolkit because older browsers do not support Object.values
.
require(['dojox/lang/functional/object'], function(Object) {
var obj = { key1: '1', key2: '2', key3: '3' };
var values = Object.values(obj);
console.log(values);
});
Output :
['1', '2', '3']
-(void) addBlurEffectOverImageView:(UIImageView *) _imageView
{
UIVisualEffect *blurEffect;
blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];
UIVisualEffectView *visualEffectView;
visualEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
visualEffectView.frame = _imageView.bounds;
[_imageView addSubview:visualEffectView];
}
$_
is the active object in the current pipeline. You've started a new pipeline with $FOLDLIST | ...
so $_
represents the objects in that array that are passed down the pipeline. You should stash the FileInfo object from the first pipeline in a variable and then reference that variable later e.g.:
write-host $NEWN.Length
$file = $_
...
Move-Item $file.Name $DPATH
The best way for accomplishing this operation in Laravel 3
seems to be the use of the Fluent
interface to truncate the table as shown below
DB::query("TRUNCATE TABLE mytable");
In iOS 5 there is a new and easy way to this. I'm not sure if the implementation is fully complete yet as it's not a gracious as, say, a UITableViewCell
, but it should definitly do the trick as it is now standard supported in the iOS API. You will not need a private API for this.
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"This is an example alert!" delegate:self cancelButtonTitle:@"Hide" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
[alert release];
This renders an alertView like this (screenshot taken from the iPhone 5.0 simulator in XCode 4.2):
When pressing any buttons, the regular delegate methods will be called and you can extract the textInput there like so:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
NSLog(@"Entered: %@",[[alertView textFieldAtIndex:0] text]);
}
Here I just NSLog the results that were entered. In production code, you should probably keep a pointer to your alertView as a global variable or use the alertView tag to check if the delegate function was called by the appropriate UIAlertView
but for this example this should be okay.
You should check out the UIAlertView API and you'll see there are some more styles defined.
Hope this helped!
-- EDIT --
I was playing around with the alertView a little and I suppose it needs no announcement that it's perfectly possible to edit the textField as desired: you can create a reference to the UITextField
and edit it as normal (programmatically).
Doing this I constructed an alertView as you specified in your original question. Better late than never, right :-)?
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Hello!" message:@"Please enter your name:" delegate:self cancelButtonTitle:@"Continue" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField * alertTextField = [alert textFieldAtIndex:0];
alertTextField.keyboardType = UIKeyboardTypeNumberPad;
alertTextField.placeholder = @"Enter your name";
[alert show];
[alert release];
This produces this alert:
You can use the same delegate method as I poster earlier to process the result from the input. I'm not sure if you can prevent the UIAlertView
from dismissing though (there is no shouldDismiss
delegate function AFAIK) so I suppose if the user input is invalid, you have to put up a new alert (or just reshow
this one) until correct input was entered.
Have fun!

I had a problem with the white screen after installing a new laravel instance. I couldn't find anything in the logs because (eventually I found out) that the reason for the white screen was that app/storage wasn't writable.
In order to get an error message on the screen I added the following to the public/index.php
try {
$app->run();
} catch(\Exception $e) {
echo "<pre>";
echo $e;
echo "</pre>";
}
After that it was easy to solve the problem.
The = way is 2-way binding, which lets you to have live changes inside your directive. When someone changes that variable out of directive, you will have that changed data inside your directive, but @ way is not two-ways binding. It works like Text. You bind once, and you will have only its value.
To get it more clearly, you can use this great article:
From the command line issue
mongo --quiet --eval "printjson(db.adminCommand('listDatabases'))"
which gives output
{
"databases" : [
{
"name" : "admin",
"sizeOnDisk" : 978944,
"empty" : false
},
{
"name" : "local",
"sizeOnDisk" : 77824,
"empty" : false
},
{
"name" : "meteor",
"sizeOnDisk" : 778240,
"empty" : false
}
],
"totalSize" : 1835008,
"ok" : 1
}
@jasonk - if you want to have "or" then negate all conditions since (A and B) <=> ~(~A or ~B)
but if you have values other than boolean try using type converters:
<MultiDataTrigger.Conditions>
<Condition Value="True">
<Condition.Binding>
<MultiBinding Converter="{StaticResource conditionConverter}">
<Binding Path="Name" />
<Binding Path="State" />
</MultiBinding>
</Condition.Binding>
<Setter Property="Background" Value="Cyan" />
</Condition>
</MultiDataTrigger.Conditions>
you can use the values in Convert method any way you like to produce a condition which suits you.
I have encountered this one too and this is my solution.
If you are encountering an invalid json object exception when parsing data, even though you know that your json string is correct, stringify the data you received in your ajax code before parsing it to JSON:
$.post(CONTEXT+"servlet/capture",{
yesTransactionId : yesTransactionId,
productOfferId : productOfferId
},
function(data){
try{
var trimData = $.trim(JSON.stringify(data));
var obj = $.parseJSON(trimData);
if(obj.success == 'true'){
//some codes ...
System.exit(0)
terminates the JVM. In simple examples like this it is difficult to percieve the difference. The parameter is passed back to the OS and is normally used to indicate abnormal termination (eg some kind of fatal error), so if you called java from a batch file or shell script you'd be able to get this value and get an idea if the application was successful.
It would make a quite an impact if you called System.exit(0)
on an application deployed to an application server (think about it before you try it).
Python's string
library has isdigit()
method:
string[0].isdigit()
Wasim's answer lead me in the right direction but I had to make some changes to get it working for my current project. I am using this function in a fragment and calling it on button click.
fun showPostDialog(title: String) {
val alert = AlertDialog.Builder(activity)
val edittext = EditText(activity)
edittext.hint = "Enter Name"
edittext.maxLines = 1
var layout = activity?.let { FrameLayout(it) }
//set padding in parent layout
// layout.isPaddingRelative(45,15,45,0)
layout?.setPadding(45,15,45,0)
alert.setTitle(title)
layout?.addView(edittext)
alert.setView(layout)
alert.setPositiveButton(getString(R.string.label_save), DialogInterface.OnClickListener {
dialog, which ->
run {
val qName = edittext.text.toString()
showToast("Posted to leaderboard successfully")
view?.hideKeyboard()
}
})
alert.setNegativeButton(getString(R.string.label_cancel), DialogInterface.OnClickListener {
dialog, which ->
run {
dialog.dismiss()
}
})
alert.show()
}
fun View.hideKeyboard() {
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(windowToken, 0)
}
fun showToast(message: String) {
Toast.makeText(activity, message, Toast.LENGTH_LONG).show()
}
I hope it helps someone else in the near future. Happy coding!
i) what is the difference between these two objects
The simple answer is that [object]
indicates a host object that has no internal class. A host object is an object that is not part of the ECMAScript implementation you're working with, but is provided by the host as an extension. The DOM is a common example of host objects, although in most newer implementations DOM objects inherit from the native Object and have internal class names (such as HTMLElement, Window, etc). IE's proprietary ActiveXObject is another example of a host object.
[object]
is most commonly seen when alerting DOM objects in Internet Explorer 7 and lower, since they are host objects that have no internal class name.
ii) what type of Object is this
You can get the "type" (internal class) of object using Object.prototype.toString
. The specification requires that it always returns a string in the format [object [[Class]]]
, where [[Class]]
is the internal class name such as Object, Array, Date, RegExp, etc. You can apply this method to any object (including host objects), using
Object.prototype.toString.apply(obj);
Many isArray
implementations use this technique to discover whether an object is actually an array (although it's not as robust in IE as it is in other browsers).
iii) what all properties does this object contains and values of each property
In ECMAScript 3, you can iterate over enumerable properties using a for...in
loop. Note that most built-in properties are non-enumerable. The same is true of some host objects. In ECMAScript 5, you can get an array containing the names of all non-inherited properties using Object.getOwnPropertyNames(obj)
. This array will contain non-enumerable and enumerable property names.

curl -ksO https://gist.githubusercontent.com/nicerobot/2697848/raw/uninstall-node.sh
chmod +x ./uninstall-node.sh
./uninstall-node.sh
rm uninstall-node.sh
Or you could check out this website: How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)
if this doesn't work, you need to remove node via control panel or any other method. As long as it gets removed.
If you use nvm
, you can use:
nvm install node
You can already check if it works, then you don't need to take the following steps with: npm -v
and then node -v
if you have nvm
installed:
command -v nvm
sudo npm uninstall npm -g
Or, if that fails, get the npm source code, and do:
sudo make uninstall
If you have nvm
installed, then use: nvm uninstall npm
npm install -g grunt
Do not use css3 variables due to support.
I would do the following if you want a pure css solution.
Use color classes with semenatic names.
.bg-primary { background: #880000; }
.bg-secondary { background: #008800; }
.bg-accent { background: #F5F5F5; }
Separate the structure from the skin (OOCSS)
/* Instead of */
h1 {
font-size: 2rem;
line-height: 1.5rem;
color: #8000;
}
/* use this */
h1 {
font-size: 2rem;
line-height: 1.5rem;
}
.bg-primary {
background: #880000;
}
/* This will allow you to reuse colors in your design */
Put these inside a separate css file to change as needed.
Notice that your error message only contains five K, V
pairs, 10 arguments total. This is by design; the ImmutableMap class provides six different of()
methods, accepting between zero and five key-value pairings. There is not an of(...)
overload accepting a varags parameter because K
and V
can be different types.
You want an ImmutableMap.Builder
:
ImmutableMap<String,String> myMap = ImmutableMap.<String, String>builder()
.put("key1", "value1")
.put("key2", "value2")
.put("key3", "value3")
.put("key4", "value4")
.put("key5", "value5")
.put("key6", "value6")
.put("key7", "value7")
.put("key8", "value8")
.put("key9", "value9")
.build();
If you create a web based application, the better solution is to check the directory exists or not then create the file if not exist. If exists, recreate again.
private File createFile(String path, String fileName) throws IOException {
ClassLoader classLoader = getClass().getClassLoader();
File file = new File(classLoader.getResource(".").getFile() + path + fileName);
// Lets create the directory
try {
file.getParentFile().mkdir();
} catch (Exception err){
System.out.println("ERROR (Directory Create)" + err.getMessage());
}
// Lets create the file if we have credential
try {
file.createNewFile();
} catch (Exception err){
System.out.println("ERROR (File Create)" + err.getMessage());
}
return file;
}
If you run docker run <NAME>
it will spawn a new image, which most likely isn't what you want.
If you want to change a current image do the following:
docker ps -a
Take the id of your target container and go to:
cd /var/lib/docker/containers/<conainerID><and then some:)>
Stop the container:
docker stop <NAME>
Change the files
vi config.v2.json
"Config": {
....
"ExposedPorts": {
"80/tcp": {},
"8888/tcp": {}
},
....
},
"NetworkSettings": {
....
"Ports": {
"80/tcp": [
{
"HostIp": "",
"HostPort": "80"
}
],
And change file
vi hostconfig.json
"PortBindings": {
"80/tcp": [
{
"HostIp": "",
"HostPort": "80"
}
],
"8888/tcp": [
{
"HostIp": "",
"HostPort": "8888"
}
]
}
Restart your docker and it should work.
If you are a Windows user, this is a common error when you use XAMPP
since LDAP
is not enabled by default.
You can follow this steps to make sure LDAP
works in your XAMPP
:
[Your Drive]:\xampp\php\php.ini
: In this file uncomment the following line:
extension=php_ldap.dll
Move the file: libsasl.dll
, from [Your Drive]:\xampp\php
to [Your Drive]:\xampp\apache\bin
(Note: moving the file is needed only for XAMPP prior to version: 5.6.28
)
Restart Apache.
You can now use functions of the LDAP Module!
If you use Linux:
For php5:
sudo apt-get install php5-ldap
For php7:
sudo apt-get install php7.0-ldap
If you are using the latest version of PHP you can do
sudo apt-get install php-ldap
running the above command should do the trick.
if for any reason it doesn't work check your php.ini configuration to enable ldap, remove the semicolon before extension=ldap
to uncomment, save and restart Apache
This expression 12-4-2005
is a calculated int and the value is -1997
. You should do like this instead '2005-04-12'
with the '
before and after.
I had the same error. The problem was this extra symbol ">" added by mistake between the tags </ComboBox.SelectedValue> and </ComboBox>:
<ComboBox
ItemsSource="{Binding StatusTypes}"
DisplayMemberPath="StatusName"
SelectedValuePath="StatusID">
<ComboBox.SelectedValue>
<Binding Path="StatusID"/>
</ComboBox.SelectedValue>
>
</ComboBox>
and here is the correct code:
<ComboBox
ItemsSource="{Binding StatusTypes}"
DisplayMemberPath="StatusName"
SelectedValuePath="StatusID">
<ComboBox.SelectedValue>
<Binding Path="StatusID"/>
</ComboBox.SelectedValue>
</ComboBox>
Indices with duplicate values often arise if you create a DataFrame by concatenating other DataFrames. IF you don't care about preserving the values of your index, and you want them to be unique values, when you concatenate the the data, set ignore_index=True
.
Alternatively, to overwrite your current index with a new one, instead of using df.reindex()
, set:
df.index = new_index
Using Visual Studio
This gives details about each assembly, app domain and has a few options to load symbols (i.e. pdb files that contain debug information).
Using Process Explorer
If you want an external tool you can use the Process Explorer (freeware, published by Microsoft)
Click on a process and it will show a list with all the assemblies used. The tool is pretty good as it shows other information such as file handles etc.
Programmatically
Check this SO question that explains how to do it.
The following WON'T WORK. It causes another issue. It will now do the 100% width but it won't be responsive on smaller devices:
.table-responsive {
display: table;
}
All these answers introduced another problem by recommending display: table;
. The only solution as of right now is to use it as a wrapper:
<div class="table-responsive">
<table class="table">
...
</table>
</div>
You don't see any output from the print
statements because FileInput
redirects stdout
to the input file when the keyword argument inplace=1
is given. This causes the input file to effectively be rewritten and if you look at it afterwards the lines in it will indeed have no trailing or leading whitespace in them (except for the newline at the end of each which the print
statement adds back).
If you only want to remove trailing whitespace, you should use rstrip()
instead of strip()
. Also note that the if lines == '': continue
is causing blank lines to be completely removed (regardless of whether strip
or rstrip
gets used).
Unless your intent is to rewrite the input file, you should probably just use for line in open(filename):
. Otherwise you can see what's being written to the file by simultaneously echoing the output to sys.stderr
using something like the following:
import fileinput
import sys
for line in (line.rstrip() for line in
fileinput.FileInput("test.txt", inplace=1)):
if line:
print line
print >>sys.stderr, line
simple write in your bat file
@cmd
or
@cmd /k "command1&command2"
Convert the JSON string to UTF-8 on your own.
@RequestMapping(value = "/example.json", method = RequestMethod.GET)
@ResponseBody
public byte[] example() throws Exception {
return "{ 'text': 'äöüß' } ".getBytes("UTF-8");
}
Python doesn't really have either concept.
It uses duck typing, which removed the need for interfaces (at least for the computer :-))
Python <= 2.5: Base classes obviously exist, but there is no explicit way to mark a method as 'pure virtual', so the class isn't really abstract.
Python >= 2.6: Abstract base classes do exist (http://docs.python.org/library/abc.html). And allow you to specify methods that must be implemented in subclasses. I don't much like the syntax, but the feature is there. Most of the time it's probably better to use duck typing from the 'using' client side.
Late answer, but you can take advantage of the fact that you can deserialize multiple objects from one JSON string, as long as the objects don't share any common property names,
public async Task<HttpResponseMessage> Post(HttpRequestMessage request)
{
var jsonString = await request.Content.ReadAsStringAsync();
var content = JsonConvert.DeserializeObject<Content >(jsonString);
var config = JsonConvert.DeserializeObject<Config>(jsonString);
}
If you are using MS Word then try ALT+E, S, U, Enter (Uses the Paste Special)
From the man page:
-h, --no-filename
Suppress the prefixing of file names on output. This is the default when there
is only one file (or only standard input) to search.
A portable solution could use getc
.
#include <stdio.h>
char buffer[MAX_FILE_SIZE];
size_t i;
for (i = 0; i < MAX_FILE_SIZE; ++i)
{
int c = getc(fp);
if (c == EOF)
{
buffer[i] = 0x00;
break;
}
buffer[i] = c;
}
If you don't want to have a MAX_FILE_SIZE
macro or if it is a big number (such that buffer
would be to big to fit on the stack), use dynamic allocation.
That's a lot of questions.
Why EOF
is -1: usually -1 in POSIX system calls is returned on error, so i guess the idea is "EOF is kind of error"
any boolean operation (including !=) returns 1 in case it's TRUE, and 0 in case it's FALSE, so getchar() != EOF
is 0
when it's FALSE, meaning getchar()
returned EOF
.
in order to emulate EOF
when reading from stdin
press Ctrl+D
For holidays, make an array of days in some format that date() can produce. Example:
// I know, these aren't holidays
$holidays = array(
'Jan 2',
'Feb 3',
'Mar 5',
'Apr 7',
// ...
);
Then use the in_array() and date() functions to check if the timestamp represents a holiday:
$day_of_year = date('M j', $timestamp);
$is_holiday = in_array($day_of_year, $holidays);
That's actually pretty easy, here's a possible approach:
<table>
<tr>
<th>
<a href="?orderBy=type">Type:</a>
</th>
<th>
<a href="?orderBy=description">Description:</a>
</th>
<th>
<a href="?orderBy=recorded_date">Recorded Date:</a>
</th>
<th>
<a href="?orderBy=added_date">Added Date:</a>
</th>
</tr>
</table>
<?php
$orderBy = array('type', 'description', 'recorded_date', 'added_date');
$order = 'type';
if (isset($_GET['orderBy']) && in_array($_GET['orderBy'], $orderBy)) {
$order = $_GET['orderBy'];
}
$query = 'SELECT * FROM aTable ORDER BY '.$order;
// retrieve and show the data :)
?>
That'll do the trick! :)
Why not just use a custom format for the cell you need to quote?
If you set a custom format to the cell column, all values will take on that format.
For numbers....like a zip code....it would be this '#' For string text, it would be this '@'
You save the file as csv format, and it will have all the quotes wrapped around the cell data as needed.
If you are clearing the cluster so that you can start again, then, in addition to what @rib47 said, I also do the following to ensure my systems are in a state ready for kubeadm init
again:
kubeadm reset -f
rm -rf /etc/cni /etc/kubernetes /var/lib/dockershim /var/lib/etcd /var/lib/kubelet /var/run/kubernetes ~/.kube/*
iptables -F && iptables -X
iptables -t nat -F && iptables -t nat -X
iptables -t raw -F && iptables -t raw -X
iptables -t mangle -F && iptables -t mangle -X
systemctl restart docker
You then need to re-install docker.io
, kubeadm
, kubectl
, and kubelet
to make sure they are at the latest versions for your distribution before you re-initialize the cluster.
EDIT: Discovered that calico adds firewall rules to the raw
table so that needs clearing out as well.
Thank you all for your answers.
Taking all of your answers as a guideline, I resolved the problem with the below code:
var valArr = [101,102];
i = 0, size = valArr.length;
for(i; i < size; i++){
$("#data").multiselect("widget").find(":checkbox[value='"+valArr[i]+"']").attr("checked","checked");
$("#data option[value='" + valArr[i] + "']").attr("selected", 1);
$("#data").multiselect("refresh");
}
Thanks once again for all your support.
I've created wsudo
, an open-source sudo
-like CLI tool for Windows to run programs or commands with elevated right, in the context of the current directory. It's available as a Chocolatey package.
I use it a lot for stuff like configuring build agents, admin things like sfc /scannow
, dism /online /cleanup-image /restorehealth
or simply for installing/updating my local Chocolatey packages. Use at your own risk.
choco install wsudo
Chocolatey must be already installed.
wsudo
is a Linux sudo
-like tool for Windows to invoke a program with elevated rights (as Administrator) from a non-admin shell command prompt and keeping its current directory.
This implementation doesn't depend on the legacy Windows Script Host (CScript
). Instead, it uses a helper PowerShell 5.1 script that invokes "Start-Process -Wait -Verb runAs ..."
cmdlet. Your system most likely already has PowerShell 5.x installed, otherwise you'll be offered to install it as a dependency.
wsudo
runs a program or an inline command with elevated rights in the current directory. Examples:
wsudo .\myAdminScript.bat
wsudox "del C:\Windows\Temp\*.* && pause"
wasudo cup all -y
wasudox start notepad C:\Windows\System32\drivers\etc\hosts

You can rewrite how your onToggleLoop method is called from your render() method.
render() {
var shuffleClassName = this.state.toggleActive ? "player-control-icon active" : "player-control-icon"
return (
<div className="player-controls">
<FontAwesome
className="player-control-icon"
name='refresh'
onClick={(event) => this.onToggleLoop(event)}
spin={this.state.loopActive}
/>
</div>
);
}
The React documentation shows this pattern in making calls to functions from expressions in attributes.
http://en.wikipedia.org/wiki/Representational_State_Transfer
The basic idea is that instead of having an ongoing connection to the server, you make a request, get some data, show that to a user, but maybe not all of it, and then when the user does something which calls for more data, or to pass some up to the server, the client initiates a change to a new state.
To remove one or more columns by name, when the column names are known (as opposed to being determined at run-time), I like the subset()
syntax. E.g. for the data-frame
df <- data.frame(a=1:3, d=2:4, c=3:5, b=4:6)
to remove just the a
column you could do
Data <- subset( Data, select = -a )
and to remove the b
and d
columns you could do
Data <- subset( Data, select = -c(d, b ) )
You can remove all columns between d
and b
with:
Data <- subset( Data, select = -c( d : b )
As I said above, this syntax works only when the column names are known. It won't work when say the column names are determined programmatically (i.e. assigned to a variable). I'll reproduce this Warning from the ?subset
documentation:
Warning:
This is a convenience function intended for use interactively. For programming it is better to use the standard subsetting functions like '[', and in particular the non-standard evaluation of argument 'subset' can have unanticipated consequences.
You can use:
overflow:hidden;
to hide the text outside the zone.
Note that it may cut the last letter (so a part of the last letter will still be displayed). A nicer way is to display an ellipsis at the end. You can do it by using text-overflow
:
overflow: hidden;
white-space: nowrap; /* Don't forget this one */
text-overflow: ellipsis;
There is something called 'locked reference' in excel which you can use for this, and you use $
symbols to lock a range. For your example, you would use:
=IF(B4<>"",B4/B$1,"")
This locks the 1
in B1
so that when you copy it to rows below, 1
will remain the same.
If you use $B$1
, the range will not change when you copy it down a row or across a column.
java.util.Date
has no specific time zone, although its value is most commonly thought of in relation to UTC. What makes you think it's in local time?
To be precise: the value within a java.util.Date
is the number of milliseconds since the Unix epoch, which occurred at midnight January 1st 1970, UTC. The same epoch could also be described in other time zones, but the traditional description is in terms of UTC. As it's a number of milliseconds since a fixed epoch, the value within java.util.Date
is the same around the world at any particular instant, regardless of local time zone.
I suspect the problem is that you're displaying it via an instance of Calendar which uses the local timezone, or possibly using Date.toString()
which also uses the local timezone, or a SimpleDateFormat
instance, which, by default, also uses local timezone.
If this isn't the problem, please post some sample code.
I would, however, recommend that you use Joda-Time anyway, which offers a much clearer API.
You can now use Modern ECMAScript syntax thanks to V8 Runtime.
You can use includes():
var grade = itemResponse.getResponse();
if(grade.includes("9th")){do something}
In case anyone else is running in to the same problem, the only solution I could find that satisfied me was to have the canvas cover everything and then to raise the Z-index of all clickable elements. You can't draw on them, but at least they are clickable...
The unglue package provides an alternative, no knowledge about regular expressions is required for simple cases, here we'd do :
# install.packages("unglue")
library(unglue)
string = c("G1:E001", "G2:E002", "G3:E003")
unglue_vec(string,"{x}:{y}", var = "y")
#> [1] "E001" "E002" "E003"

You can use Pillow.
pip install Pillow
image = base64.b64decode(str(base64String))
fileName = 'test.jpeg'

img.save(imagePath, 'jpeg')

I ran into the same problem and was able to resolve it in very powerful way that allows unlimited sorting possibilities.
I created a View using (saving) 2 sort orders (*explanation on how to do so below).
After that I simply applied the update queries to the View created and it worked great.
Here are the 2 queries I used on the view:
1st Query:
Update MyView
Set SortID=0
2nd Query:
DECLARE @sortID int
SET @sortID = 0
UPDATE MyView
SET @sortID = sortID = @sortID + 1
*To be able to save the sorting on the View I put TOP into the SELECT statement. This very useful workaround allows the View results to be returned sorted as set when the View was created when the View is opened. In my case it looked like:
(NOTE: Using this workaround will place an big load on the server if using a large table and it is therefore recommended to include as few fields as possible in the view if working with large tables)
SELECT TOP (600000)
dbo.Items.ID, dbo.Items.Code, dbo.Items.SortID, dbo.Supplier.Date,
dbo.Supplier.Code AS Expr1
FROM dbo.Items INNER JOIN
dbo.Supplier ON dbo.Items.SupplierCode = dbo.Supplier.Code
ORDER BY dbo.Supplier.Date, dbo.Items.ID DESC

This two threads explain it better:

Your server needs to have the php modules installed so it can parse php code.
If you are on ubuntu you can do this easily with
sudo apt-get install apache2
sudo apt-get install php5
sudo apt-get install libapache2-mod-php5
sudo /etc/init.d/apache2 restart
Otherwise you may compile apache with php: http://dan.drydog.com/apache2php.html
Specifying your server OS will help others to answer more specifically.
Two ways I know of:
export class SomeComponent implements OnInit
{
public localVar:any;
ngOnInit(){
this.http.get(Path).map(res => res.json()).subscribe(res => this.localVar = res);
}
}
This will assign your result into local variable once information is returned just like in a promise. Then you just do {{ localVar }}
Another Way is to get a observable as a localVariable.
export class SomeComponent
{
public localVar:any;
constructor()
{
this.localVar = this.http.get(path).map(res => res.json());
}
}
This way you're exposing a observable at which point you can do in your html is to use AsyncPipe {{ localVar | async }}
Please try it out and let me know if it works. Also, since angular 2 is pretty new, feel free to comment if something is wrong.
Hope it helps

I know the question asking for Spring boot, but I believe lot of people looking for how to do this in non Spring boot, like me searching almost whole day.
Above Spring 4, there is no need to configure MappingJacksonHttpMessageConverter
if you only intend to configure ObjectMapper
.
You just need to do:
public class MyObjectMapper extends ObjectMapper {
private static final long serialVersionUID = 4219938065516862637L;
public MyObjectMapper() {
super();
enable(SerializationFeature.INDENT_OUTPUT);
}
}
And in your Spring configuration, create this bean:
@Bean
public MyObjectMapper myObjectMapper() {
return new MyObjectMapper();
}
There is no button type cancel https://www.w3schools.com/jsref/prop_pushbutton_type.asp
To achieve cancel functionality I used DOM history
<button type="button" class="btn btn-primary" onclick="window.history.back();">Cancel</button>
_x000D_
For more details : https://www.w3schools.com/jsref/met_his_back.asp
1) Open your project url: https://github.com/someuser/project-name
2) in the top, aside of the project name, click EDIT
class App():
def __init__(self):
self.root = Tkinter.Tk()
button = Tkinter.Button(self.root, text = 'root quit', command=self.quit)
button.pack()
self.root.mainloop()
def quit(self):
self.root.destroy()
app = App()
The above were really close. Here's my solution:
Private Sub getDsClone(ByRef inClone As DataSet, ByVal matchStr As String, ByRef outClone As DataSet)
Dim i As Integer
outClone = inClone.Clone
Dim dv As DataView = inClone.Tables(0).DefaultView
dv.RowFilter = matchStr
Dim dt As New DataTable
dt = dv.ToTable
For i = 0 To dv.Count - 1
outClone.Tables(0).ImportRow(dv.Item(i).Row)
Next
End Sub
You need to escape the dot if you want to split on a literal dot:
String extensionRemoved = filename.split("\\.")[0];
Otherwise you are splitting on the regex .
, which means "any character".
Note the double backslash needed to create a single backslash in the regex.
You're getting an ArrayIndexOutOfBoundsException
because your input string is just a dot, ie "."
, which is an edge case that produces an empty array when split on dot; split(regex)
removes all trailing blanks from the result, but since splitting a dot on a dot leaves only two blanks, after trailing blanks are removed you're left with an empty array.
To avoid getting an ArrayIndexOutOfBoundsException
for this edge case, use the overloaded version of split(regex, limit)
, which has a second parameter that is the size limit for the resulting array. When limit
is negative, the behaviour of removing trailing blanks from the resulting array is disabled:
".".split("\\.", -1) // returns an array of two blanks, ie ["", ""]
ie, when filename
is just a dot "."
, calling filename.split("\\.", -1)[0]
will return a blank, but calling filename.split("\\.")[0]
will throw an ArrayIndexOutOfBoundsException
.

I have used the code of Oliver Crow (link given by Andrew Hare) and adapted it a bit to tailor Python 2.7.3. (by using timeit package). I ran on my personal computer, Lenovo T61, 6GB RAM, Debian GNU/Linux 6.0.6 (squeeze).
Here is the result for 10,000 iterations:

It is quite obvious that Python guys have done pretty great job to optimize string concatenation, and as Hoare said: "premature optimization is the root of all evil" :-)
I found some answers, but I don't know if it is the right way.This is my solution for now. Fortunatelly it didn´t broke my design mode.
`
/// <summary>
/// set config, if key is not in file, create
/// </summary>
/// <param name="key">Nome do parâmetro</param>
/// <param name="value">Valor do parâmetro</param>
public static void SetConfig(string key, string value)
{
var configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var settings = configFile.AppSettings.Settings;
if (settings[key] == null)
{
settings.Add(key, value);
}
else
{
settings[key].Value = value;
}
configFile.Save(ConfigurationSaveMode.Modified);

In the above example, 'add' is a static method that takes two integers as arguments.
Following snippet is used to call 'add' method with input 1 and 2.
Class myClass = Class.forName("Add");
Method method = myClass.getDeclaredMethod("add", int.class, int.class);
Object result = method.invoke(null, 1, 2);

I noticed that this question was not marked as answered after 2 years - I think the closest answer is Richards, but it can be simplified quite a lot to this:
list1.Concat(list2)
.ToLookup(p => p.Name)
.Select(g => g.Aggregate((p1, p2) => new Person
{
Name = p1.Name,
Value = p1.Value,
Change = p2.Value - p1.Value
}));
Although this won't error in the case where you have duplicate names in either set.
Some other answers have suggested using unioning - this is definitely not the way to go as it will only get you a distinct list, without doing the combining.
If you're open to using a third-party library, you can use the Collectors2
class in Eclipse Collections to convert the List
to a Bag
using a Stream
. A Bag
is a data structure that is built for counting.
Bag<String> counted =
list.stream().collect(Collectors2.countBy(each -> each));
Assert.assertEquals(1, counted.occurrencesOf("World"));
Assert.assertEquals(2, counted.occurrencesOf("Hello"));
System.out.println(counted.toStringOfItemToCount());
Output:
{World=1, Hello=2}
In this particular case, you can simply collect
the List
directly into a Bag
.
Bag<String> counted =
list.stream().collect(Collectors2.toBag());
You can also create the Bag
without using a Stream
by adapting the List
with the Eclipse Collections protocols.
Bag<String> counted = Lists.adapt(list).countBy(each -> each);
or in this particular case:
Bag<String> counted = Lists.adapt(list).toBag();
You could also just create the Bag directly.
Bag<String> counted = Bags.mutable.with("Hello", "Hello", "World");
A Bag<String>
is like a Map<String, Integer>
in that it internally keeps track of keys and their counts. But, if you ask a Map
for a key it doesn't contain, it will return null
. If you ask a Bag
for a key it doesn't contain using occurrencesOf
, it will return 0.
Note: I am a committer for Eclipse Collections.
The accepted answer is good, but if you are using it to get values from a textView in android, it would be good to check if the string is empty. If the string is empty it would throw an exception.
private String capitizeString(String name){
String captilizedString="";
if(!name.trim().equals("")){
captilizedString = name.substring(0,1).toUpperCase() + name.substring(1);
}
return captilizedString;
}
If you simply want to squash all commits into a single, initial commit, just reset the repository and amend the first commit:
git reset hash-of-first-commit
git add -A
git commit --amend
Git reset will leave the working tree intact, so everything is still there. So just add the files using git add commands, and amend the first commit with these changes. Compared to rebase -i you'll lose the ability to merge the git comments though.
Use break
.
Unrelated to your question, I see in your code the line:
Violated = !(name.firstname == null) ? false : true;
In this line, you take a boolean value (name.firstname == null)
. Then, you apply the !
operator to it. Then, if the value is true, you set Violated to false; otherwise to true. So basically, Violated is set to the same value as the original expression (name.firstname == null)
. Why not use that, as in:
Violated = (name.firstname == null);
You can easily use a list to wrap the required object and that's all what django serializers need to correctly serialize it, eg.:
from django.core import serializers
# assuming obj is a model instance
serialized_obj = serializers.serialize('json', [ obj, ])
With a signal handler.
Here is a simple example flipping a bool
used in main()
:
#include <signal.h>
static volatile int keepRunning = 1;
void intHandler(int dummy) {
keepRunning = 0;
}
// ...
int main(void) {
signal(SIGINT, intHandler);
while (keepRunning) {
// ...
Edit in June 2017: To whom it may concern, particularly those with an insatiable urge to edit this answer. Look, I wrote this answer seven years ago. Yes, language standards change. If you really must better the world, please add your new answer but leave mine as is. As the answer has my name on it, I'd prefer it to contain my words too. Thank you.
After encountering the same issue in a Web API 2 project (and being unable to use the standard CORS packages for reasons not worth going into here), I was able to resolve this by implementing a custom DelagatingHandler:
public class AllowOptionsHandler : DelegatingHandler
{
protected override async Task<HttpResponseMessage> SendAsync(
HttpRequestMessage request, CancellationToken cancellationToken)
{
var response = await base.SendAsync(request, cancellationToken);
if (request.Method == HttpMethod.Options &&
response.StatusCode == HttpStatusCode.MethodNotAllowed)
{
response = new HttpResponseMessage(HttpStatusCode.OK);
}
return response;
}
}
For the Web API configuration:
config.MessageHandlers.Add(new AllowOptionsHandler());
Note that I also have the CORS headers enabled in Web.config, similar to some of the other answers posted here:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule" />
</modules>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Headers" value="accept, cache-control, content-type, authorization" />
<add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
</customHeaders>
</httpProtocol>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="TRACEVerbHandler" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
Note that my project does not include MVC, only Web API 2.
If you are working with API, then you can use it as:
import moment from 'moment'
...
this.state = {
List: []
};
}
componentDidMount() {
this.getData();
}
// Show List
getData() {
fetch('url')
.then((response) => {
response.json()
.then((result) => {
this.setState({ List: result })
})
})
}
this.state.List =
this.state.List.map(row => ({...row, dob: moment(row.dob).format("YYYY/MM/DD")}))
...
A while
applies to the expression or block after the while
.
You dont have a block, so your while ends with the expression dog=al.get(i);
while(dog.getId()!=id && i<length)
dog=al.get(i);
Everything after that happens only once.
There's no reason to new up a Dog, as you're never using the dog you new'd up; you immediately assign a Dog from the array to your dog reference.
And if you need to get a value for a key, you should use a Map, not an Array.
Edit: this was donwmodded why??
Comment from OP:
One further question with regards to not having to make a new instance of a Dog. If I am just taking out copies of the objects from the array list, how can I then take it out from the array list without having an object in which I put it? I just noticed as well that I didn't bracket the while-loop.
A Java reference and the object it refers to are different things. They're very much like a C++ reference and object, though a Java reference can be re-pointed like a C++ pointer.
The upshot is that Dog dog;
or Dog dog = null
gives you a reference that points to no object. new Dog()
creates an object that can be pointed to.
Following that with a dog = al.get(i)
means that the reference now points to the dog reference returned by al.get(i)
. Understand, in Java, objects are never returned, only references to objects (which are addresses of the object in memory).
The pointer/reference/address of the Dog you newed up is now lost, as no code refers to it, as the referent was replaced with the referent you got from al.get()
. Eventually the Java garbage collector will destroy that object; in C++ you'd have "leaked" the memory.
The upshot is that you do need to create a variable that can refer to a Dog; you don't need to create a Dog with new
.
(In truth you don't need to create a reference, as what you really ought to be doing is returning what a Map returns from its get() function. If the Map isn't parametrized on Dog, like this: Map<Dog>
, then you'll need to cast the return from get, but you won't need a reference: return (Dog) map.get(id);
or if the Map is parameterized, return map.get(id)
. And that one line is your whole function, and it'll be faster than iterating an array for most cases.)
As mentioned in the above answer, by updating the bashrc file you can run the pycharm.sh from anywhere on the linux terminal.
But if you love the icon and wants the Desktop shortcuts for the Pycharm on Ubuntu OS then follow the Below steps,
Quick way to create Pycharm launcher.
1. Start Pycharm using the pycharm.sh cmd from anywhere on the terminal or start the pycharm.sh located under bin folder of the pycharm artifact.
2. Once the Pycharm application loads, navigate to tools menu and select “Create Desktop Entry..”
3. Check the box if you want the launcher for all users.
4. If you Check the box i.e “Create entry for all users”, you will be asked for your password.
5. A message should appear informing you that it was successful.
6. Now Restart Pycharm application and you will find Pycharm in Unity dash and Application launcher.."
Stop using the TEXT
data type in SQL Server!
It's been deprecated since the 2005 version. Use VARCHAR(MAX)
instead, if you need more than 8000 characters.
The TEXT
data type doesn't support the normal string functions, while VARCHAR(MAX)
does - your statement would work just fine, if you'd be using just VARCHAR types.
by now the mounting works on some machines (ubuntu) and some doesn't (centos 7) but installing the plugin solves it
vagrant plugin install vagrant-vbguest
without having to do anything else on top of that, just
vagrant reload
It's worth mentioning that you can use the NODE_ENV
environment variable to achieve the same result. Particularly useful if you're containerizing your Node application (e.g. Docker).
NODE_ENV=production npm install
The above code will install all your dependencies but the dev ones (i.e. devDependencies
).
if you need to use environment variables in your Dockerfile
more information can be found here.
Environment variables are easy to overwrite whenever needed (e.g. if you want to run your test suite say on Travis CI). If that were the case you could do something like this:
docker run -v $(pwd):/usr/src/app --rm -it -e NODE_ENV=production node:8 npm install
production
- Default: false
Type: Boolean Set to true to run in "production" mode.
- devDependencies are not installed at the topmost level when running local npm install without any arguments.
- Set the NODE_ENV="production" for lifecycle scripts.
Happy containerization =)
Following this: http://developer.android.com/reference/android/text/format/Time.html
Is better to use Android native Time class:
Time now = new Time();
now.setToNow();
Then format:
Log.d("DEBUG", "Time "+now.format("%d.%m.%Y %H.%M.%S"));
You can transform array of strings to array of numbers in one line:
const arrayOfNumbers = arrayOfStrings.map(e => +e);
I don't believe that the framework itself has this class. Maybe a third-party library...
But why not create a Period value-object class to handle this complexity? That way you can ensure other constraints, like validating start vs end datetimes. Something like:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Whatever.Domain.Timing {
public class Period {
public DateTime StartDateTime {get; private set;}
public DateTime EndDateTime {get; private set;}
public Period(DateTime StartDateTime, DateTime EndDateTime) {
if (StartDateTime > EndDateTime)
throw new InvalidPeriodException("End DateTime Must Be Greater Than Start DateTime!");
this.StartDateTime = StartDateTime;
this.EndDateTime = EndDateTime;
}
public bool Overlaps(Period anotherPeriod){
return (this.StartDateTime < anotherPeriod.EndDateTime && anotherPeriod.StartDateTime < this.EndDateTime)
}
public TimeSpan GetDuration(){
return EndDateTime - StartDateTime;
}
}
public class InvalidPeriodException : Exception {
public InvalidPeriodException(string Message) : base(Message) { }
}
}
That way you will be able to individually compare each period...
I tried "ManiIOT"'s solution and it worked surprisingly. I've added another role (Compute Admin Role) for my google user account from IAM admin. Then stopped and restarted the VM. Afterwards 'sudo passwd' let me to generate a new password for the user.
So here are steps.
I really liked Al P's answer but wanted uniqueness enforced cheaply so I took it one step further - use a directory. There are some obvious limitations (directory file limits, invalid file names) but it should work for most cases.
hinit() {
rm -rf /tmp/hashmap.$1
mkdir -p /tmp/hashmap.$1
}
hput() {
printf "$3" > /tmp/hashmap.$1/$2
}
hget() {
cat /tmp/hashmap.$1/$2
}
hkeys() {
ls -1 /tmp/hashmap.$1
}
hdestroy() {
rm -rf /tmp/hashmap.$1
}
hinit ids
for (( i = 0; i < 10000; i++ )); do
hput ids "key$i" "value$i"
done
for (( i = 0; i < 10000; i++ )); do
printf '%s\n' $(hget ids "key$i") > /dev/null
done
hdestroy ids
It also performs a tad bit better in my tests.
$ time bash hash.sh
real 0m46.500s
user 0m16.767s
sys 0m51.473s
$ time bash dirhash.sh
real 0m35.875s
user 0m8.002s
sys 0m24.666s
Just thought I'd pitch in. Cheers!
Edit: Adding hdestroy()
This will do the trick

The problem is that your method does NOT return a list of TestA if it contains a TestB, so what if it was correctly typed? Then this cast:
class TestA{};
class TestB extends TestA{};
List<? extends TestA> listA;
List<TestB> listB = (List<TestB>) listA;
works about as well as you could hope for (Eclipse warns you of an unchecked cast which is exactly what you are doing, so meh). So can you use this to solve your problem? Actually you can because of this:
List<TestA> badlist = null; // Actually contains TestBs, as specified
List<? extends TestA> talist = badlist; // Umm, works
List<TextB> tblist = (List<TestB>)talist; // TADA!
Exactly what you asked for, right? or to be really exact:
List<TestB> tblist = (List<TestB>)(List<? extends TestA>) badlist;
seems to compile just fine for me.
Probably your simple json.jar file isn't in your classpath.
Shortest, most safe and easiest solution is:
long myValue=...;
int asInt = Long.valueOf(myValue).intValue();
Do note, the behavior of Long.valueOf
is as such:
Using this code:
System.out.println("Long max: " + Long.MAX_VALUE);
System.out.println("Int max: " + Integer.MAX_VALUE);
long maxIntValue = Integer.MAX_VALUE;
System.out.println("Long maxIntValue to int: " + Long.valueOf(maxIntValue).intValue());
long maxIntValuePlusOne = Integer.MAX_VALUE + 1;
System.out.println("Long maxIntValuePlusOne to int: " + Long.valueOf(maxIntValuePlusOne).intValue());
System.out.println("Long max to int: " + Long.valueOf(Long.MAX_VALUE).intValue());
Results into:
Long max: 9223372036854775807
Int max: 2147483647
Long max to int: -1
Long maxIntValue to int: 2147483647
Long maxIntValuePlusOne to int: -2147483648
In case you want to pass some parameters to your shell script, you can use the method shlex.split():
import subprocess
import shlex
subprocess.call(shlex.split('./test.sh param1 param2'))
with test.sh
in the same folder:
#!/bin/sh
echo $1
echo $2
exit 0
Outputs:
$ python test.py
param1
param2
list(map(chr, [66, 53, 0, 94]))
map(func, *iterables) --> map object Make an iterator that computes the function using arguments from each of the iterables. Stops when the shortest iterable is exhausted.
"Make an iterator"
means it will return an iterator.
"that computes the function using arguments from each of the iterables"
means that the next() function of the iterator will take one value of each iterables and pass each of them to one positional parameter of the function.
So you get an iterator from the map() funtion and jsut pass it to the list() builtin function or use list comprehensions.
If you want to change inputs in an iframe then submit the form from that iframe, do this
...
var el = document.getElementById('targetFrame');
var doc, frame_win = getIframeWindow(el); // getIframeWindow is defined below
if (frame_win) {
doc = (window.contentDocument || window.document);
}
if (doc) {
doc.forms[0].someInputName.value = someValue;
...
doc.forms[0].submit();
}
...
Normally, you can only do this if the page in the iframe is from the same origin, but you can start Chrome in a debug mode to disregard the same origin policy and test this on any page.
function getIframeWindow(iframe_object) {
var doc;
if (iframe_object.contentWindow) {
return iframe_object.contentWindow;
}
if (iframe_object.window) {
return iframe_object.window;
}
if (!doc && iframe_object.contentDocument) {
doc = iframe_object.contentDocument;
}
if (!doc && iframe_object.document) {
doc = iframe_object.document;
}
if (doc && doc.defaultView) {
return doc.defaultView;
}
if (doc && doc.parentWindow) {
return doc.parentWindow;
}
return undefined;
}
Converting the object to JSON, and then parsing it, works for me, like:
JSON.parse(JSON.stringify(object))
The quintessential example of this is an array of pointers to structs or objects (that are mutable).
A shallow copy copies the array and maintains references to the original objects.
A deep copy will copy (clone) the objects too so they bear no relation to the original. Implicit in this is that the object themselves are deep copied. This is where it gets hard because there's no real way to know if something was deep copied or not.
The copy constructor is used to initilize the new object with the previously created object of the same class. By default compiler wrote a shallow copy. Shallow copy works fine when dynamic memory allocation is not involved because when dynamic memory allocation is involved then both objects will points towards the same memory location in a heap, Therefore to remove this problem we wrote deep copy so both objects have their own copy of attributes in a memory.
In order to read the details with complete examples and explanations you could see the article Constructors and destructors.
The default copy constructor is shallow. You can make your own copy constructors deep or shallow, as appropriate. See C++ Notes: OOP: Copy Constructors.
If you are able to use external libraries I would recommend you to use Joda-Time, noting that:
Joda-Time is the de facto standard date and time library for Java prior to Java SE 8. Users are now asked to migrate to java.time (JSR-310).
Example for between calculation:
Seconds.between(startDate, endDate);
Days.between(startDate, endDate);
The pyplot functions you are calling, axhline()
and axvline()
draw lines that span a portion of the axis range, regardless of coordinates. The parameters xmin
or ymin
use value 0.0 as the minimum of the axis and 1.0 as the maximum of the axis.
Instead, use plt.plot((x1, x2), (y1, y2), 'k-')
to draw a line from the point (x1, y1) to the point (x2, y2) in color k. See pyplot.plot
.
hifarrer's full solution is very helpful to me.
but, I met many other problems - supporting other mime type, listing capture devices(camera, video, audio recoder), opening capture device immediately(ex: <input accept="image/*;capture"> )...
So, I made a solution that works exactly same as default web browser app.

UPDATE #1 (2015.09.09)
adds code for Android 5.0.1 compatability.
You can use an XMLHttpRequest to load a page into a div (or any other element of your page really). An exemple function would be:
function loadPage(){
if (window.XMLHttpRequest){
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}else{
// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById("ID OF ELEMENT YOU WANT TO LOAD PAGE IN").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("POST","WEBPAGE YOU WANT TO LOAD",true);
xmlhttp.send();
}
If your sever is capable, you could also use PHP to do this, but since you're asking for an HTML5 method, this should be all you need.
You get an extension ID when you upload your extension to Google Web Store. Ie. Adblock has URL https://chrome.google.com/webstore/detail/cfhdojbkjhnklbpkdaibdccddilifddb
and the last part of this URL is its extension ID cfhdojbkjhnklbpkdaibdccddilifddb
.
If you wish to read installed extension IDs from your extension, check out the managment module. chrome.management.getAll
allows to fetch information about all installed extensions.
List<Integer> intList = strList.stream()
.map(Integer::valueOf)
.collect(Collectors.toList());
whats about using this way:
public enum HL_COLORS{
YELLOW,
ORANGE;
public int getColorValue() {
switch (this) {
case YELLOW:
return 0xffffff00;
case ORANGE:
return 0xffffa500;
default://YELLOW
return 0xffffff00;
}
}
}
there is only one method ..
you can use static method and pass the Enum as parameter like:
public enum HL_COLORS{
YELLOW,
ORANGE;
public static int getColorValue(HL_COLORS hl) {
switch (hl) {
case YELLOW:
return 0xffffff00;
case ORANGE:
return 0xffffa500;
default://YELLOW
return 0xffffff00;
}
}
Note that these two ways use less memory and more process units .. I don't say this is the best way but its just another approach.
With the code d.Contains(b + a)
you check if "You hit someone for 50 damage" contains "someonedamage". And this (i guess) you don't want.
The + concats the two string of b and a.
You have to check it by
if(d.Contains(b) && d.Contains(a))
While the accepted answer is technically correct, a more practical approach, if possible, is to just strip whitespace out of both the regular expression and the search string.
If you want to search for "my cats", instead of:
myString.match(/m\s*y\s*c\s*a\*st\s*s\s*/g)
Just do:
myString.replace(/\s*/g,"").match(/mycats/g)
Warning: You can't automate this on the regular expression by just replacing all spaces with empty strings because they may occur in a negation or otherwise make your regular expression invalid.
You can use the JFileChooser class, check this example.
Yeah, use .match
, rather than .search
. The result from the .match
call will return the actual string that was matched itself, but it can still be used as a boolean value.
var string = "Stackoverflow is the BEST";
var result = string.match(/best/i);
// result == 'BEST';
if (result){
alert('Matched');
}
Using a regular expression like that is probably the tidiest and most obvious way to do that in JavaScript, but bear in mind it is a regular expression, and thus can contain regex metacharacters. If you want to take the string from elsewhere (eg, user input), or if you want to avoid having to escape a lot of metacharacters, then you're probably best using indexOf
like this:
matchString = 'best';
// If the match string is coming from user input you could do
// matchString = userInput.toLowerCase() here.
if (string.toLowerCase().indexOf(matchString) != -1){
alert('Matched');
}
Well, to match the first scenario, this is something I've come up with.
Essentially, instead of binding the "click" event, you bind the "change" event with the alert.
Then, when you trigger the event, first you trigger click, then trigger change.
By default a span
is an inline
element... so that's not the default behavior.
You can make the span
behave that way by adding display: block;
to your CSS.
span {
display: block;
width: 100px;
}
I've tried different ways of blocking scrolling when the arrow keys are pressed, both jQuery and native Javascript - they all work fine in Firefox, but don't work in recent versions of Chrome.
Even the explicit {passive: false}
property for window.addEventListener
, which is recommended as the only working solution, for example here.
In the end, after many tries, I found a way that works for me in both Firefox and Chrome:
window.addEventListener('keydown', (e) => {
if (e.target.localName != 'input') { // if you need to filter <input> elements
switch (e.keyCode) {
case 37: // left
case 39: // right
e.preventDefault();
break;
case 38: // up
case 40: // down
e.preventDefault();
break;
default:
break;
}
}
}, {
capture: true, // this disables arrow key scrolling in modern Chrome
passive: false // this is optional, my code works without it
});
Quote for EventTarget.addEventListener()
from MDN
options Optional
An options object specifies characteristics about the event listener. The available options are:capture
ABoolean
indicating that events of this type will be dispatched to the registeredlistener
before being dispatched to anyEventTarget
beneath it in the DOM tree.
once
...
passive
ABoolean
that, if true, indicates that the function specified bylistener
will never callpreventDefault()
. If a passive listener does callpreventDefault()
, the user agent will do nothing other than generate a console warning. ...
Use
ping -D 8.8.8.8
From the man page
-D Print timestamp (unix time + microseconds as in gettimeofday) before each line

A really simple way to do this...
// create the option
var opt = $("<option>").val("myvalue").text("my text");
//append option to the select element
$(#my-select).append(opt);
This could be done in lots of ways, even in a single line if really you want to.
Yep:
WITH tab (
bla bla
)
INSERT INTO dbo.prf_BatchItemAdditionalAPartyNos ( BatchID, AccountNo,
APartyNo,
SourceRowID)
SELECT * FROM tab
Note that this is for SQL Server, which supports multiple CTEs:
WITH x AS (), y AS () INSERT INTO z (a, b, c) SELECT a, b, c FROM y
Teradata allows only one CTE and the syntax is as your example.
If you iterate over a dictionary you get the keys, so assuming your dictionary is in a variable called data
and you have some function find_definition()
which gets the definition, you can do something like the following:
for word in data:
data[word] = find_definition(word)
With borrowing from this post we know about choosing between the multithreading, multiprocessing, and async/asyncio
and their usage.
Python 3 has a new built-in library in order to make concurrency and parallelism: concurrent.futures
So I'll demonstrate through an experiment to run four tasks (i.e. .sleep()
method) by Threading-Pool
:
from concurrent.futures import ThreadPoolExecutor, as_completed
from time import sleep, time
def concurrent(max_worker):
futures = []
tic = time()
with ThreadPoolExecutor(max_workers=max_worker) as executor:
futures.append(executor.submit(sleep, 2)) # Two seconds sleep
futures.append(executor.submit(sleep, 1))
futures.append(executor.submit(sleep, 7))
futures.append(executor.submit(sleep, 3))
for future in as_completed(futures):
if future.result() is not None:
print(future.result())
print(f'Total elapsed time by {max_worker} workers:', time()-tic)
concurrent(5)
concurrent(4)
concurrent(3)
concurrent(2)
concurrent(1)
Output:
Total elapsed time by 5 workers: 7.007831811904907
Total elapsed time by 4 workers: 7.007944107055664
Total elapsed time by 3 workers: 7.003149509429932
Total elapsed time by 2 workers: 8.004627466201782
Total elapsed time by 1 workers: 13.013478994369507
[NOTE]:
multiprocessing
instead of threading
) you can change the ThreadPoolExecutor
to ProcessPoolExecutor
.Make two static cultures, one for comma and one for point.
var commaCulture = new CultureInfo("en")
{
NumberFormat =
{
NumberDecimalSeparator = ","
}
};
var pointCulture = new CultureInfo("en")
{
NumberFormat =
{
NumberDecimalSeparator = "."
}
};
Then use each one respectively, depending on the input (using a function):
public double ConvertToDouble(string input)
{
input = input.Trim();
if (input == "0") {
return 0;
}
if (input.Contains(",") && input.Split(',').Length == 2)
{
return Convert.ToDouble(input, commaCulture);
}
if (input.Contains(".") && input.Split('.').Length == 2)
{
return Convert.ToDouble(input, pointCulture);
}
throw new Exception("Invalid input!");
}
Then loop through your arrays
var strings = new List<string> {"0,12", "0.122", "1,23", "00,0", "0.00", "12.5000", "0.002", "0,001"};
var doubles = new List<double>();
foreach (var value in strings) {
doubles.Add(ConvertToDouble(value));
}
This should work even though the host environment and culture changes.
In case this can help anyone, here's simple CSS as a jumping off point. Turns it into a basic rounded square big enough for thumbs with a toggled background color.
input[type='checkbox'] {_x000D_

Ted Hopp answered this quite nicely. I have been using res/raw for my opengl texture and shader files. I was thinking about moving them to an assets directory to provide a hierarchical organization.
This thread convinced me not to. First, because I like the use of a unique resource id. Second because it's very simple to use InputStream/openRawResource or BitmapFactory to read in the file. Third because it's very useful to be able to use in a portable library.
In order to get a Date (that can be used in JPA later on), I did
Date startOfMonth = Date.from(LocalDate.now().withDayOfMonth(1).atStartOfDay().toInstant(ZoneOffset.UTC));

As you went through the tutorial you must have come across the section on migration, as this was one of the major changes in Django 1.7
Prior to Django 1.7, the syncdb command never made any change that had a chance to destroy data currently in the database. This meant that if you did syncdb for a model, then added a new row to the model (a new column, effectively), syncdb would not affect that change in the database.
So either you dropped that table by hand and then ran syncdb again (to recreate it from scratch, losing any data), or you manually entered the correct statements at the database to add only that column.
Then a project came along called south
which implemented migrations. This meant that there was a way to migrate forward (and reverse, undo) any changes to the database and preserve the integrity of data.
In Django 1.7, the functionality of south
was integrated directly into Django. When working with migrations, the process is a bit different.
models.py
(as normal).makemigrations
command. This command is smart enough to detect what has changed and will create a script to effect that change to your database.migrate
. This command applies all migrations in order.So your normal syncdb
is now a two-step process, python manage.py makemigrations
followed by python manage.py migrate
.
Now, on to your specific problem:
class Snippet(models.Model):
owner = models.ForeignKey('auth.User', related_name='snippets')
highlighted = models.TextField()
created = models.DateTimeField(auto_now_add=True)
title = models.CharField(max_length=100, blank=True, default='')
code = models.TextField()
linenos = models.BooleanField(default=False)
language = models.CharField(choices=LANGUAGE_CHOICES,
default='python',
max_length=100)
style = models.CharField(choices=STYLE_CHOICES,
default='friendly',
max_length=100)
In this model, you have two fields highlighted
and code
that is required (they cannot be null).
Had you added these fields from the start, there wouldn't be a problem because the table has no existing rows?
However, if the table has already been created and you add a field that cannot be null, you have to define a default value to provide for any existing rows - otherwise, the database will not accept your changes because they would violate the data integrity constraints.
This is what the command is prompting you about. You can tell Django to apply a default during migration, or you can give it a "blank" default highlighted = models.TextField(default='')
in the model itself.
Here's how to do with cv2 in Python:
# Create a blank 300x300 black image
image = np.zeros((300, 300, 3), np.uint8)
# Fill image with red color(set each pixel to red)
image[:] = (0, 0, 255)
Here's more complete example how to create new blank image filled with a certain RGB color
import cv2
import numpy as np
def create_blank(width, height, rgb_color=(0, 0, 0)):
"""Create new image(numpy array) filled with certain color in RGB"""
# Create black blank image
image = np.zeros((height, width, 3), np.uint8)
# Since OpenCV uses BGR, convert the color first
color = tuple(reversed(rgb_color))
# Fill image with color
image[:] = color
return image
# Create new blank 300x300 red image
width, height = 300, 300
red = (255, 0, 0)
image = create_blank(width, height, rgb_color=red)
cv2.imwrite('red.jpg', image)
You need to specify the executable path of Git in the Git Settings, as mentionned in the per-requesites:
The Git integration plugin is enabled and the location of the Git executable file is correctly specified on the Git page of the Settings dialog box.
As long as you see "a message indicating that the Git execution path is not correct", the rest of the instructions won't work.
Path to Git executable
In this text box, specify the path to the Git executable file.
Type the path manually or click the Browse button to open theSelect Path - Git Configuration
dialog box and select the location of the Git executable file in the directories tree.
See "Where is git.exe located?" for the path of Git on Windows.
with Git for Windows:
C:\Program Files\Git\mingw64\bin
OR
c:\path\to\PortableGit-2.6.2-64-bit\usr\bin
OR
c:\path\to\PortableGit-2.x.\mingw64\bin
With GitHub Desktop:
%USERPROFILE%\AppData\Local\GitHub\PORTAB~1\bin\git.exe
Update 2020, three years later:
As noted by Daniel Connelly in the comments
IntelliJ now lets people install it through the path specified in the help above (just look for the "
Download Now
" button on the Git menu).
If you download Git from the website, a version that IntelliJ does not support will be installed.
I made a new way without having a background drawable is that make it have CardView as parent and give it a app:cardCornerRadius="20dp"
and then add this in the java class dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
It's another way to make it .
To complement Jon Lin's answer, here is a no-trailing-slash technique that also works if the website is located in a directory (like example.org/blog/):
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [R=301,L]
For the sake of completeness, here is an alternative emphasizing that REQUEST_URI
starts with a slash (at least in .htaccess
files):
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} /(.*)/$
RewriteRule ^ /%1 [R=301,L] <-- added slash here too, don't forget it
Just don't use %{REQUEST_URI} (.*)/$
. Because in the root directory REQUEST_URI
equals /
, the leading slash, and it would be misinterpreted as a trailing slash.

(update: this technique is now implemented in Laravel 5.5)
print "Number of lines: $nids\n";
print "Content: $ids\n";
How did Perl complain? print $ids
should work, though you probably want a newline at the end, either explicitly with print
as above or implicitly by using say
or -l/$\.
If you want to interpolate a variable in a string and have something immediately after it that would looks like part of the variable but isn't, enclose the variable name in {}
:
print "foo${ids}bar";
The most obvious, language independent, answer is to use a series of 'if'.
If the language you are using has function pointers (C) or has functions that are 1st class values (Lua) you may achieve results similar to a "switch" using an array (or a list) of (pointers to) functions.
You should be more specific on the language if you want better answers.
