UPDATE:
If you want to take advantage of Imagick (if it is installed on your server). Note: I didn't use Imagick's nature writeFile
because I was having issues with it on my server. File put contents works just as well.

I have been using this, just execute the function after you store the original image and use that location to create the thumbnail. Edit it to your liking...
function makeThumbnails($updir, $img, $id)
{
$thumbnail_width = 134;
$thumbnail_height = 189;
$thumb_beforeword = "thumb";
$arr_image_details = getimagesize("$updir" . $id . '_' . "$img"); // pass id to thumb name
$original_width = $arr_image_details[0];
$original_height = $arr_image_details[1];
if ($original_width > $original_height) {
$new_width = $thumbnail_width;
$new_height = intval($original_height * $new_width / $original_width);
} else {
$new_height = $thumbnail_height;
$new_width = intval($original_width * $new_height / $original_height);
}
$dest_x = intval(($thumbnail_width - $new_width) / 2);
$dest_y = intval(($thumbnail_height - $new_height) / 2);
if ($arr_image_details[2] == IMAGETYPE_GIF) {
$imgt = "ImageGIF";
$imgcreatefrom = "ImageCreateFromGIF";
}
if ($arr_image_details[2] == IMAGETYPE_JPEG) {
$imgt = "ImageJPEG";
$imgcreatefrom = "ImageCreateFromJPEG";
}
if ($arr_image_details[2] == IMAGETYPE_PNG) {
$imgt = "ImagePNG";
$imgcreatefrom = "ImageCreateFromPNG";
}
if ($imgt) {
$old_image = $imgcreatefrom("$updir" . $id . '_' . "$img");
$new_image = imagecreatetruecolor($thumbnail_width, $thumbnail_height);
imagecopyresized($new_image, $old_image, $dest_x, $dest_y, 0, 0, $new_width, $new_height, $original_width, $original_height);
$imgt($new_image, "$updir" . $id . '_' . "$thumb_beforeword" . "$img");
}
}
The above function creates images with a uniform thumbnail size. If the image doesn't have the same dimensions as the specified thumbnail size (proportionally), it just has blackspace on the top and bottom.

You need to run following command to kill the process. Find out the id of the process which you wanted to kill by
> show processlist;
Take the value from id column and fire below command
kill query <processId>;
Query parameter specifies that we need to kill query command process.
The syntax for kill process as follows
KILL [CONNECTION | QUERY] processlist_id

You could move the common parts to another configuration file and include
from both server contexts. This should work:
server {
listen 80;
server_name server1.example;
...
include /etc/nginx/include.d/your-common-stuff.conf;
}
server {
listen 80;
server_name another-one.example;
...
include /etc/nginx/include.d/your-common-stuff.conf;
}
Edit: Here's an example that's actually copied from my running server. I configure my basic server settings in /etc/nginx/sites-enabled
(normal stuff for nginx on Ubuntu/Debian). For example, my main server bunkus.org
's configuration file is /etc/nginx/sites-enabled
and it looks like this:
server {
listen 80 default_server;
listen [2a01:4f8:120:3105::101:1]:80 default_server;
include /etc/nginx/include.d/all-common;
include /etc/nginx/include.d/bunkus.org-common;
include /etc/nginx/include.d/bunkus.org-80;
}
server {
listen 443 default_server;
listen [2a01:4f8:120:3105::101:1]:443 default_server;
include /etc/nginx/include.d/all-common;
include /etc/nginx/include.d/ssl-common;
include /etc/nginx/include.d/bunkus.org-common;
include /etc/nginx/include.d/bunkus.org-443;
}
As an example here's the /etc/nginx/include.d/all-common
file that's included from both server
contexts:
index index.html index.htm index.php .dirindex.php;
try_files $uri $uri/ =404;
location ~ /\.ht {
deny all;
}
location = /favicon.ico {
log_not_found off;

}
In Info.plist set 'View controller-based status bar appearance' as NO
In AppDelegate add

FYI, If you're using inline styles or modifying the DOM directly (for instance adding an element), workspaces don't solve this problem. That's because the DOM is living in memory and there's not an actual file associated with the active state of the DOM.
For that, I like to take a "before" and "after" snapshot of the dom from the console:
copy(document.getElementsByTagName('html')[0].outerHTML)
Then I place it in a diff tool to see my changes.

You have two choices for getting a microsecond timestamp. The first (and best) choice, is to use the timeval
type directly:
struct timeval GetTimeStamp() {
struct timeval tv;
gettimeofday(&tv,NULL);
return tv;
}
The second, and for me less desirable, choice is to build a uint64_t out of a timeval
:
uint64_t GetTimeStamp() {
struct timeval tv;
gettimeofday(&tv,NULL);
return tv.tv_sec*(uint64_t)1000000+tv.tv_usec;
}
In bubble sort in ith iteration you have n-i-1 inner iterations (n^2)/2 total, but in insertion sort you have maximum i iterations on i'th step, but i/2 on average, as you can stop inner loop earlier, after you found correct position for the current element. So you have (sum from 0 to n) / 2 which is (n^2) / 4 total;
That's why insertion sort is faster than bubble sort.
this works for me
yum install python-devel mysql-devel
If the StudentNumber is numeric it will not be sorted numeric but alphanumeric. Do not expect
"2" < "11"
it will be:
"11" < "2"
I needed to print important warning about skipped tests exactly when PyTest
muted literally everything.
I didn't want to fail a test to send a signal, so I did a hack as follow:
def test_2_YellAboutBrokenAndMutedTests():
import atexit
def report():
print C_patch.tidy_text("""
In silent mode PyTest breaks low level stream structure I work with, so
I cannot test if my functionality work fine. I skipped corresponding tests.
Run `py.test -s` to make sure everything is tested.""")
if sys.stdout != sys.__stdout__:
atexit.register(report)
The atexit
module allows me to print stuff after PyTest
released the output streams. The output looks as follow:
============================= test session starts ==============================
platform linux2 -- Python 2.7.3, pytest-2.9.2, py-1.4.31, pluggy-0.3.1

In silent mode PyTest breaks low level stream structure I work with, so

~/.../sources/C_patch$
Message is printed even when PyTest
is in silent mode, and is not printed if you run stuff with py.test -s
, so everything is tested nicely already.
Amazon's CloudFront content delivery network can now be configured to pass this information through as a header. Given Amazon's size (they're big and stable, not going anywhere) and this is configuration over code (no third-party API to learn or code to maintain), all around believe this to be the best option.
If you do not use AWS CloudFront, I'd look into seeing if your CDN has a similar header option that can be turned on. Usually the large providers are quick to push for feature parity. And if you are not using a CDN, you could put CloudFront in front of your infrastructure and simply set the origin to resolve to whatever you are currently using.
Additionally, it also makes sense to resolve this at the CDN level. Your CDN is already having to figure out geo location to route the user to the nearest content node, might as well pass this information along and not figure it out twice through a third party API (this becomes chokepoint for your app, waiting for a geo location lookup to resolve). No need to do this work twice (and the second time, arguably less resilient [e.g., 3rd party geo lookup]).
https://aws.amazon.com/blogs/aws/enhanced-cloudfront-customization/
Geo-Targeting – CloudFront will detect the user’s country of origin and pass along the county code to you in the
CloudFront-Viewer-Country
header. You can use this information to customize your responses without having to use URLs that are specific to each country.
Please note that --tests
option may not work if you have different build types/flavors
(fails with Unknown command-line option '--tests'
). In this case, it's necessary to specify the particular test task (e.g. testProdReleaseUnitTest
instead of just test
)
The results of the execution time directly contradict the results of the Query Cost, but I'm having difficulty determining what "Query Cost" actually means.
Query cost
is what optimizer thinks of how long your query will take (relative to total batch time).
The optimizer tries to choose the optimal query plan by looking at your query and statistics of your data, trying several execution plans and selecting the least costly of them.
Here you may read in more detail about how does it try to do this.
As you can see, this may differ significantly of what you actually get.
The only real query perfomance metric is, of course, how long does the query actually take.
I had the same problem and I found this solution working with bindParam :
bindParam(':param', $myvar = NULL, PDO::PARAM_INT);
An <iframe>
gives you a complete window to work with. The most direct way to do what you want is to have your server give you a complete page that only contains the fragment you want to show.
As an alternative, you could just use a simple <div>
and use the jQuery "load" function to load the whole page and pluck out just the section you want:
$('#target-div').load('http://www.mywebsite.com/portfolio.php #portfolio-sports');
There may be other things you need to do, and a significant difference is that the content will become part of the main page instead of being segregated into a separate window.

Backticks are commonly used for multi-line strings or when you want to interpolate an expression within your string

let address = 'address';_x000D_
let address2 = 'address2222';_x000D_

I use this as part of my utils. With this we can not only set shadow but also can get a rounded corner for any UIView
. Also you could set what color shadow you prefer. Normally black is preferred but sometimes, when the background is non-white you might want something else. Here's what I use -
in utils.m
+ (void)roundedLayer:(CALayer *)viewLayer
radius:(float)r
shadow:(BOOL)s
{
[viewLayer setMasksToBounds:YES];
[viewLayer setCornerRadius:r];
[viewLayer setBorderColor:[RGB(180, 180, 180) CGColor]];
[viewLayer setBorderWidth:1.0f];
if(s)
{
[viewLayer setShadowColor:[RGB(0, 0, 0) CGColor]];
[viewLayer setShadowOffset:CGSizeMake(0, 0)];
[viewLayer setShadowOpacity:1];
[viewLayer setShadowRadius:2.0];
}
return;
}
To use this we need to call this - [utils roundedLayer:yourview.layer radius:5.0f shadow:YES];
You can use the option -C
(or --directory
if you prefer long options) to give the target directory of your choice in case you are using the Gnu version of tar
. The directory should exist:
mkdir foo
tar -xzf bar.tar.gz -C foo
If you are not using a tar
capable of extracting to a specific directory, you can simply cd
into your target directory prior to calling tar
; then you will have to give a complete path to your archive, of course. You can do this in a scoping subshell to avoid influencing the surrounding script:
mkdir foo
(cd foo; tar -xzf ../bar.tar.gz) # instead of ../ you can use an absolute path as well
Or, if neither an absolute path nor a relative path to the archive file is suitable, you also can use this to name the archive outside of the scoping subshell:
TARGET_PATH=a/very/complex/path/which/might/even/be/absolute
mkdir -p "$TARGET_PATH"
(cd "$TARGET_PATH"; tar -xzf -) < bar.tar.gz
I had the same problem and i found the following solution to be very efficient. I hope that it will help you or everyone else who wants to do the same thing.
First of all, i would start with a "with" statement as it ensures the proper open/close of the file.
It should look something like this:
with open("filename.txt", "r+") as f:
contents = [x.strip() for x in f.readlines()]
If you want to convert those strings (every item in the contents list is a string) in integer or float you can do the following:
contents = [float(contents[i]) for i in range(len(contents))]
Use int
instead of float
if you want to convert to integer.
It's my first answer in SO, so sorry if it's not in the proper formatting.

Here's an extension method I wrote to handle multiple image and/or text buttons.
Here's the HTML for an image button:
<input id="btnJoin" name="Join" src="/content/images/buttons/btnJoin.png"
type="image">
or for a text submit button :
<input type="submit" class="ui-button green" name="Submit_Join" value="Add to cart" />
<input type="submit" class="ui-button red" name="Submit_Skip" value="Not today" />
Here is the extension method you call from the controller with form.GetSubmitButtonName()
. For image buttons it looks for a form parameter with .x
(which indicates an image button was clicked) and extracts the name. For regular input
buttons it looks for a name beginning with Submit_
and extracts the command from afterwards. Because I'm abstracting away the logic of determining the 'command' you can switch between image + text buttons on the client without changing the server side code.
public static class FormCollectionExtensions
{
public static string GetSubmitButtonName(this FormCollection formCollection)
{
return GetSubmitButtonName(formCollection, true);
}
public static string GetSubmitButtonName(this FormCollection formCollection, bool throwOnError)
{
var imageButton = formCollection.Keys.OfType<string>().Where(x => x.EndsWith(".x")).SingleOrDefault();
var textButton = formCollection.Keys.OfType<string>().Where(x => x.StartsWith("Submit_")).SingleOrDefault();
if (textButton != null)
{
return textButton.Substring("Submit_".Length);
}
// we got something like AddToCart.x
if (imageButton != null)
{
return imageButton.Substring(0, imageButton.Length - 2);
}
if (throwOnError)
{
throw new ApplicationException("No button found");
}
else
{
return null;
}
}
}
Note: For text buttons you have to prefix the name with Submit_
. I prefer this way becuase it means you can change the text (display) value without having to change the code. Unlike SELECT
elements, an INPUT
button has only a 'value' and no separate 'text' attribute. My buttons say different things under different contexts - but map to the same 'command'. I much prefer extracting the name this way than having to code for == "Add to cart"
.
This issue occurs when you add a third-party library with @drawable/ic_launcher attribute thus android merger is unable to differentiate your app icon attribute and the library's attribute. To solve this add this line in your manifest file under the application tag
tools:replace="android:icon"
It marks a method, that it will be implemented in other languages, not in Java. It works together with JNI (Java Native Interface).
Native methods were used in the past to write performance critical sections but with Java getting faster this is now less common. Native methods are currently needed when
You need to call a library from Java that is written in other language.
You need to access system or hardware resources that are only reachable from the other language (typically C). Actually, many system functions that interact with real computer (disk and network IO, for instance) can only do this because they call native code.
See Also Java Native Interface Specification
I don't think you can get it directly, but there are a few ways to find it indirectly.
One way is to use the GC.GetTotalMemory
method to measure the amount of memory used before and after creating your object. This won't be perfect, but as long as you control the rest of the application you may get the information you are interested in.
Apart from that you can use a profiler to get the information or you could use the profiling api to get the information in code. But that won't be easy to use I think.
See Find out how much memory is being used by an object in C#? for a similar question.

I just encountered this issue. My resolution was to update the system time by manually syncing to the time servers. To do this you can:
Adjust Date/Time
Internet Time
tabChange Settings
Update Now
In my case this was syncing incorrectly so I had to click it several times before it updated correctly. If it continues to update incorrectly you can even try using a different time server from the server drop-down.
Use ternary operator:
echo (($test == '') ? $redText : '');
echo $test == '' ? $redText : ''; //removed parenthesis
But in this case you can't use shorter reversed version because it will return bool(true)
in first condition.
echo (($test != '') ?: $redText); //this will not work properly for this case
Also make sure you do not wrap parentheses around your query string like so:
SELECT Name from [USER] WHERE [UserId] in (@ids)
I had this cause a SQL Syntax error using Dapper 1.50.2, fixed by removing parentheses
SELECT Name from [USER] WHERE [UserId] in @ids
The object viewer in Acrobat is good but Windjack Solution's PDF Canopener allows better inspection with an eyedropper for selecting objects on page. Also permits modifications to be made to PDF.
Building on Brad Larson's answer, if you have major and minor version info stored in the info plist (as I did on a particular project), this worked well for me:
- (NSString *)appNameAndVersionNumberDisplayString {
NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
NSString *appDisplayName = [infoDictionary objectForKey:@"CFBundleDisplayName"];
NSString *majorVersion = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
NSString *minorVersion = [infoDictionary objectForKey:@"CFBundleVersion"];
return [NSString stringWithFormat:@"%@, Version %@ (%@)",
appDisplayName, majorVersion, minorVersion];
}
Now revving a minor version manually can be a pain, and so using a source repository revision number trick is ideal. If you've not tied that in (as I hadn't), the above snippet can be useful. It also pulls out the app's display name.
See, here you can get only date by passing a format string. You can get a different date format as per your requirement as given below for current date:
DateTime.Now.ToString("M/d/yyyy");
Result : "9/1/2015"
DateTime.Now.ToString("M-d-yyyy");
Result : "9-1-2015"
DateTime.Now.ToString("yyyy-MM-dd");
Result : "2015-09-01"
DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss");
Result : "2015-09-01 09:20:10"

In my case, it was also caused by old dlls. Clean all your files then rebuild.
Setting a custom font to a regular ProgressDialog/AlertDialog:
font=Typeface.createFromAsset(getAssets(),"DroidSans.ttf");
ProgressDialog dialog = ProgressDialog.show(this, "titleText", "messageText", true);
((TextView)dialog.findViewById(Resources.getSystem().getIdentifier("message", "id", "android"))).setTypeface(font);
((TextView)dialog.findViewById(Resources.getSystem().getIdentifier("alertTitle", "id", "android"))).setTypeface(font);
My current answer already has the most votes, but I found a better, and more modern, way of doing this.
class MyObject
{
public int id { get; set; }
public string title { get; set; }
}
ObservableCollection<MyObject> myCollection = new ObservableCollection<MyObject>();
//add stuff to collection
// .
// .
// .
myCollection = new ObservableCollection<MyObject>(
myCollection.OrderBy(n => n.title, Comparer<string>.Create(
(x, y) => (Utils.Utils.LogicalStringCompare(x, y)))));
Googling gives me this:
Command A & Command B
Execute Command A, then execute Command B (no evaluation of anything)
Command A | Command B
Execute Command A, and redirect all its output into the input of Command B
Command A && Command B
Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B
Command A || Command B
Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B
You need to convert the String object into an array of char using the toCharArray
() method of the String class:
String str = "xyz";
char arr[] = str.toCharArray(); // convert the String object to array of char
// iterate over the array using the for-each loop.
for(char c: arr){
System.out.println(c);
}
Scanner sc = new Scanner(System.in);
System.out.println("\n number of input sets::");
int value=sc.nextInt();
System.out.println("\n input sets::");
int[] inputset;
inputset = new int[value];
for(int i=0;i<value;i++)
{
inputset[i]=sc.nextInt();
}
int maxvalue=inputset[0];
int secondval=inputset[0];
for(int i=1;i<value;i++)
{
if(inputset[i]>maxvalue)
{
maxvalue=inputset[i];
}
}
for(int i=1;i<value;i++)
{
if(inputset[i]>secondval && inputset[i]<maxvalue)
{
secondval=inputset[i];
}
}
System.out.println("\n maxvalue"+ maxvalue);
System.out.println("\n secondmaxvalue"+ secondval);

Firstly, see the different between absolute path and relative path here:
An absolute path always contains the root element and the complete directory list required to locate the file.
Alternatively, a relative path needs to be combined with another path in order to access a file.
In constructor File(String pathname), Javadoc's File class said that
A pathname, whether abstract or in string form, may be either absolute or relative.
If you want to get relative path, you must be define the path from the current working directory to file or directory.Try to use system properties to get this.As the pictures that you drew:
String localDir = System.getProperty("user.dir");
File file = new File(localDir + "\\config.properties");
Moreover, you should try to avoid using similar ".", "../", "/", and other similar relative to the file location relative path, because when files are moved, it is harder to handle.
You possibly do not have create permissions to the folder. So WinSCP fails to create a temporary file for the transfer.
You have two options:

Just follow these Steps :
If you want the contents of, say, C1 to mirror the contents of cell A1, you just need to set the formula in C1 to =A1. From this point forward, anything you type in A1 will show up in C1 as well.
To Link Multiple Cells in Excel From Another Worksheet :
Step 1
Click the worksheet tab at the bottom of the screen that contains a range of precedent cells to which you want to link. A range is a block or group of adjacent cells. For example, assume you want to link a range of blank cells in “Sheet1” to a range of precedent cells in “Sheet2.” Click the “Sheet2” tab.
Step 2
Determine the precedent range’s width in columns and height in rows. In this example, assume cells A1 through A4 on “Sheet2” contain a list of numbers 1, 2, 3 and 4, respectively, which will be your precedent cells. This precedent range is one column wide by four rows high.
Step 3
Click the worksheet tab at the bottom of the screen that contains the blank cells in which you will insert a link. In this example, click the “Sheet1” tab.
Step 4
Select the range of blank cells you want to link to the precedent cells. This range must be the same size as the precedent range, but can be in a different location on the worksheet. Click and hold the mouse button on the top left cell of the range, drag the mouse cursor to the bottom right cell in the range and release the mouse button to select the range. In this example, assume you want to link cells C1 through C4 to the precedent range. Click and hold on cell C1, drag the mouse to cell C4 and release the mouse to highlight the range.
Step 5
Type “=,” the worksheet name containing the precedent cells, “!,” the top left cell of the precedent range, “:” and the bottom right cell of the precedent range. Press “Ctrl,” “Shift” and “Enter” simultaneously to complete the array formula. Each dependent cell is now linked to the cell in the precedent range that’s in the same respective location within the range. In this example, type “=Sheet2!A1:A4” and press “Ctrl,” “Shift” and “Enter” simultaneously. Cells C1 through C4 on “Sheet1” now contain the array formula “{=Sheet2!A1:A4}” surrounded by curly brackets, and show the same data as the precedent cells in “Sheet2.”
Good Luck !!!
If you want help an object go away, set its reference to null.
String x = "sadfasdfasd";
// do stuff
x = null;
Setting reference to null will make it more likely that the object will be garbage collected, as long as there are no other references to the object.
Looks like you are trying to open a directory for reading as if it's a regular file. Many OSs won't let you do that. You don't need to anyway, because what you want (judging from your description) is
x_file = open(os.path.join(direct, "5_1.txt"), "r")
or simply
x_file = open(direct+"/5_1.txt", "r")
Looks like /e
option is what you need, it'll skip same files/directories.
robocopy c:\data c:\backup /e
If you run the command twice, you'll see the second round is much faster since it skips a lot of things.

In the first question, you don't need an event listener on every input that would be wasteful.
Instead, listen for the enter key and to find the currently focused element use document.activeElement
window.onkeypress = function(e) {
if (e.which == 13) {
e.preventDefault();
var nextInput = inputs.get(inputs.index(document.activeElement) + 1);
if (nextInput) {
nextInput.focus();
}
}
};
One event listener is better than many, especially on low power / mobile browsers.

:last-child
is really the only way to do it without modifying the HTML - but assuming you can do that, the main option is just to give it a class="last-item"
, then do:
li.last-item { /* ... */ }
Obviously, you can automate this in the dynamic page generation language of your choice. Also, there is a lastChild
JavaScript property in the W3C DOM.
Here's an example of doing what you want in Prototype:
$$("ul").each(function(x) { $(x.lastChild).addClassName("last-item"); });
Or even more simply:
$$("ul li:last-child").each(function(x) { x.addClassName("last-item"); });
In jQuery, you can write it even more compactly:
$("ul li:last-child").addClass("last-item");
Also note that this should work without using the actual last-child
CSS selector - rather, a JavaScript implementation of it is used - so it should be less buggy and more reliable across browsers.

In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There are Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os.
Solution
~/.matplotlib
. ~/.matplotlib/matplotlibrc
there and add the following code: backend: TkAgg
From this link you can try different diagrams.
Use:
List<String> x = new ArrayList<>(Arrays.asList("xyz", "abc"));
If you don't want to add new elements to the list later, you can also use (Arrays.asList returns a fixed-size list):
List<String> x = Arrays.asList("xyz", "abc");
Note: you can also use a static import if you like, then it looks like this:
import static java.util.Arrays.asList;
...
List<String> x = new ArrayList<>(asList("xyz", "abc"));
or
List<String> x = asList("xyz", "abc");
I was facing very similar problem while trying to insert data using mysql-connector-net-5.1.7-noinstall and Visual Studio(2015) in Windows Form Application. I am not a C# guru. So, it takes around 2 hours to resolve everything.
The following code works lately:
string connetionString = null;
connetionString = "server=localhost;database=device_db;uid=root;pwd=123;";
using (MySqlConnection cn = new MySqlConnection(connetionString))
{
try
{
string query = "INSERT INTO test_table(user_id, user_name) VALUES (?user_id,?user_name);";
cn.Open();
using (MySqlCommand cmd = new MySqlCommand(query, cn))
{
cmd.Parameters.Add("?user_id", MySqlDbType.Int32).Value = 123;
cmd.Parameters.Add("?user_name", MySqlDbType.VarChar).Value = "Test username";
cmd.ExecuteNonQuery();
}
}
catch (MySqlException ex)
{
MessageBox.Show("Error in adding mysql row. Error: "+ex.Message);
}
}
Instead of using the windows load event use the ready event on the document.
$(document).ready(function(){[...]});
This should fire when everything in the DOM is ready to go, including media content fully loaded.

If You are looking list of methods which respond by an instance (in your case @current_user). According to ruby documentation methods
Returns a list of the names of public and protected methods of obj. This will include all the methods accessible in obj's ancestors. If the optional parameter is false, it returns an array of obj's public and protected singleton methods, the array will not include methods in modules included in obj.
@current_user.methods
@current_user.methods(false) #only public and protected singleton methods and also array will not include methods in modules included in @current_user class or parent of it.
Alternatively, You can also check that a method is callable on an object or not?.
@current_user.respond_to?:your_method_name
If you don't want parent class methods then just subtract the parent class methods from it.
@current_user.methods - @current_user.class.superclass.new.methods #methods that are available to @current_user instance.
If both of your servers are using WHM, I think we can reduce the time to nil. Create your domain in the new server and set everything ready. Go to the previous server and delete the account corresponding to that domain. Until now I have got no errors by doing this and felt the update instantaneous. FYI I used hostgator hosting (both dedicated servers). And I really dont know why it is so. It's supposed to be not like that until the TTL is over.
You could do something like this
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:6740/api/Membership/exist");
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = 6;
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
And then strReponse should contain the values returned by your webservice
A big difference is if you are displaying arrays. Especially ones with NIL. For example:
print [nil, 1, 2]
gives
[nil, 1, 2]
but
puts [nil, 1, 2]
gives
1
2
Note, no appearing nil item (just a blank line) and each item on a different line.
There are several options available*:
*Disclaimer: This list may not be complete.
Using Flexbox
Nowadays, we can use flexbox. It is quite a handy alternative to the css-transform option. I would use this solution almost always. If it is just one element maybe not, but for example if I had to support an array of data e.g. rows and columns and I want them to be relatively centered in the very middle.
.flexbox {
display: flex;
height: 100px;
flex-flow: row wrap;
align-items: center;
justify-content: center;
background-color: #eaeaea;
border: 1px dotted #333;
}
.item {
/* default => flex: 0 1 auto */
background-color: #fff;
border: 1px dotted #333;
box-sizing: border-box;
}
_x000D_
<div class="flexbox">
<div class="item">I am centered in the middle.</div>
<div class="item">I am centered in the middle, too.</div>
</div>
_x000D_
Using CSS 2D-Transform
This is still a good option, was also the accepted solution back in 2015.
It is very slim and simple to apply and does not mess with the layouting of other elements.
.boxes {
position: relative;
}
.box {
position: relative;
display: inline-block;
float: left;
width: 200px;
height: 200px;
font-weight: bold;
color: #333;
margin-right: 10px;
margin-bottom: 10px;
background-color: #eaeaea;
}
.h-center {
text-align: center;
}
.v-center span {
position: absolute;
left: 0;
right: 0;
top: 50%;
transform: translate(0, -50%);
}
_x000D_
<div class="boxes">
<div class="box h-center">horizontally centered lorem ipsun dolor sit amet</div>
<div class="box v-center"><span>vertically centered lorem ipsun dolor sit amet lorem ipsun dolor sit amet</span></div>
<div class="box h-center v-center"><span>horizontally and vertically centered lorem ipsun dolor sit amet</span></div>
</div>
_x000D_
Note: This does also work with
:after
and:before
pseudo-elements.
Using Grid
This might just be an overkill, but it depends on your DOM. If you want to use grid anyway, then why not. It is very powerful alternative and you are really maximum flexible with the design.
Note: To align the items vertically we use flexbox in combination with grid. But we could also use
display: grid
on the items.
.grid {
display: grid;
width: 400px;
grid-template-rows: 100px;
grid-template-columns: 100px 100px 100px;
grid-gap: 3px;
align-items: center;
justify-content: center;
background-color: #eaeaea;
border: 1px dotted #333;
}
.item {
display: flex;
justify-content: center;
align-items: center;
border: 1px dotted #333;
box-sizing: border-box;
}
.item-large {
height: 80px;
}
_x000D_
<div class="grid">
<div class="item">Item 1</div>
<div class="item item-large">Item 2</div>
<div class="item">Item 3</div>
</div>

I suggest looking at this gcc page which discusses the tradeoffs between the "cfront" and "borland" model for template instantiations.
https://gcc.gnu.org/onlinedocs/gcc-4.6.4/gcc/Template-Instantiation.html
The "borland" model corresponds to what the author suggests, providing the full template definition, and having things compiled multiple times.
It contains explicit recommendations concerning using manual and automatic template instantiation. For example, the "-repo" option can be used to collect templates which need to be instantiated. Or another option is to disable automatic template instantiations using "-fno-implicit-templates" to force manual template instantiation.
In my experience, I rely on the C++ Standard Library and Boost templates being instantiated for each compilation unit (using a template library). For my large template classes, I do manual template instantiation, once, for the types I need.
This is my approach because I am providing a working program, not a template library for use in other programs. The author of the book, Josuttis, works a lot on template libraries.
If I was really worried about speed, I suppose I would explore using Precompiled Headers https://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html
which is gaining support in many compilers. However, I think precompiled headers would be difficult with template header files.
I tried about three different ways of intercepting the construction of the Ajax object:
xhrFields
, but that only allows for one listener, only attaches to download (not upload) progress, and requires what seems like unnecessary copy-and-paste. progress
function to the returned promise, but I had to maintain my own array of handlers. I could not find a good object to attach the handlers because one place I'd access to the XHR and another I'd have access to the jQuery XHR, but I never had access to the deferred object (only its promise). ajax
with my own. The only potential shortcoming is you can no longer use your own xhr()
setting. You can allow for that by checking to see whether options.xhr
is a function.I actually call my promise.progress
function xhrProgress
so I can easily find it later. You might want to name it something else to separate your upload and download listeners. I hope this helps someone even if the original poster already got what he needed.
(function extend_jQuery_ajax_with_progress( window, jQuery, undefined )
{
var $originalAjax = jQuery.ajax;
jQuery.ajax = function( url, options )
{
if( typeof( url ) === 'object' )
{options = url;url = undefined;}
options = options || {};
// Instantiate our own.
var xmlHttpReq = $.ajaxSettings.xhr();
// Make it use our own.
options.xhr = function()
{return( xmlHttpReq );};
var $newDeferred = $.Deferred();
var $oldPromise = $originalAjax( url, options )
.done( function done_wrapper( response, text_status, jqXHR )
{return( $newDeferred.resolveWith( this, arguments ));})
.fail( function fail_wrapper( jqXHR, text_status, error )
{return( $newDeferred.rejectWith( this, arguments ));})
.progress( function progress_wrapper()
{
window.console.warn( "Whoa, jQuery started actually using deferred progress to report Ajax progress!" );
return( $newDeferred.notifyWith( this, arguments ));
});
var $newPromise = $newDeferred.promise();
// Extend our own.
$newPromise.progress = function( handler )
{
xmlHttpReq.addEventListener( 'progress', function download_progress( evt )
{
//window.console.debug( "download_progress", evt );
handler.apply( this, [evt]);
}, false );
xmlHttpReq.upload.addEventListener( 'progress', function upload_progress( evt )
{
//window.console.debug( "upload_progress", evt );
handler.apply( this, [evt]);
}, false );
return( this );
};
return( $newPromise );
};
})( window, jQuery );
defaultMember
already is an alias - it doesn't need to be the name of the exported function/thing. Just do
import alias from 'my-module';
Alternatively you can do
import {default as alias} from 'my-module';
but that's rather esoteric.
axios.get
accepts a request config as the second parameter (not query string params).
You can use the params
config option to set query string params as follows:
axios.get('/api', {
params: {
foo: 'bar'
}
});
I took Crystalonics' answer and turned them into extension methods. I hope someone else will find them useful:
public static byte[] SerializeToByteArray(this object obj)
{
if (obj == null)
{
return null;
}
var bf = new BinaryFormatter();
using (var ms = new MemoryStream())
{
bf.Serialize(ms, obj);
return ms.ToArray();
}
}
public static T Deserialize<T>(this byte[] byteArray) where T : class
{
if (byteArray == null)
{
return null;
}
using (var memStream = new MemoryStream())
{
var binForm = new BinaryFormatter();
memStream.Write(byteArray, 0, byteArray.Length);
memStream.Seek(0, SeekOrigin.Begin);
var obj = (T)binForm.Deserialize(memStream);
return obj;
}
}
If I understand well, you want to Join ScheduleRequest
with User
and apply the in
clause to the userName
property of the entity User
.
I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join
part (because it handles the Join
logic outside the Criteria Query).
List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);
In order to write more type-safe code you could also use Metamodel by replacing this line:
Expression<String> exp = scheduleRequest.get("createdBy");
with this:
Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);
If it works, then you may try to add the Join
logic into the Criteria Query
. But right now I can't test it, so I prefer to see if somebody else wants to try.
Not a perfect answer though may be code snippets might help.
public <T> List<T> findListWhereInCondition(Class<T> clazz,
String conditionColumnName, Serializable... conditionColumnValues) {
QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
addWhereInClause(queryBuilder, conditionColumnName,
conditionColumnValues);
queryBuilder.select();
return queryBuilder.getResultList();
}
private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
String conditionColumnName, Serializable... conditionColumnValues) {
Path<Object> path = queryBuilder.root.get(conditionColumnName);
In<Object> in = queryBuilder.criteriaBuilder.in(path);
for (Serializable conditionColumnValue : conditionColumnValues) {
in.value(conditionColumnValue);
}
queryBuilder.criteriaQuery.where(in);
}
The error is telling you that x
doesn’t even exist! It hasn’t been declared, which is different than being assigned a value.
var x; // declaration
x = 2; // assignment
If you declared x
, you wouldn’t get an error. You would get an alert that says undefined
because x
exists/has been declared but hasn’t been assigned a value.
To check if the variable has been declared, you can use typeof
, any other method of checking if a variable exists will raise the same error you got initially.
if(typeof x !== "undefined") {
alert(x);
}
This is checking the type of the value stored in x
. It will only return undefined
when x
hasn’t been declared OR if it has been declared and was not yet assigned.
You asked about performance. See this perf test comparing 'concat', '+' and 'join' - in short the + operator wins by far.

You need to use the option -f
:
$ grep -f A B
The option -F
does a fixed string search where as -f
is for specifying a file of patterns. You may want both if the file only contains fixed strings and not regexps.
$ grep -Ff A B
You may also want the -w
option for matching whole words only:
$ grep -wFf A B
Read man grep
for a description of all the possible arguments and what they do.
Even if a builtin way existed, it wouldn't validate it as greater than today and it would differ very little from a substring call. I wouldn't worry about it.

INSERT OR REPLACE INTO table(column_list) VALUES(value_list);
For REPLACE to execute correctly your table structure must have unique rows, whether a simple primary key or a unique index.
REPLACE deletes, then INSERTs the record and will cause an INSERT Trigger to execute if you have them setup. If you have a trigger on INSERT, you may encounter issues.
This is a work around.. not checked the speed..
INSERT OR IGNORE INTO table (column_list) VALUES(value_list);
followed by
UPDATE table SET field=value,field2=value WHERE uniqueid='uniquevalue'
This method allows a replace to occur without causing a trigger.
There are four abstract function types, you can use them separately when you know your function will take an argument(s) or not, will return a data or not.
export declare type fEmptyVoid = () => void;
export declare type fEmptyReturn = () => any;
export declare type fArgVoid = (...args: any[]) => void;
export declare type fArgReturn = (...args: any[]) => any;
like this:
public isValid: fEmptyReturn = (): boolean => true;
public setStatus: fArgVoid = (status: boolean): void => this.status = status;
For use only one type as any function type we can combine all abstract types together, like this:
export declare type fFunction = fEmptyVoid | fEmptyReturn | fArgVoid | fArgReturn;
then use it like:
public isValid: fFunction = (): boolean => true;
public setStatus: fFunction = (status: boolean): void => this.status = status;
In the example above everything is correct. But the usage example in bellow is not correct from the point of view of most code editors.
// you can call this function with any type of function as argument
public callArgument(callback: fFunction) {
// but you will get editor error if call callback argument like this
callback();
}
Correct call for editors is like this:
public callArgument(callback: fFunction) {
// pay attention in this part, for fix editor(s) error
(callback as fFunction)();
}
To answer @desmond.carros question, I modified the best answer as follows,
import random
file=open("datafile.txt","r")
data=list()
for line in file:
data.append(line.split(#your preferred delimiter))
file.close()
random.shuffle(data)
train_data = data[:int((len(data)+1)*.80)] #Remaining 80% to training set
test_data = data[int((len(data)+1)*.80):] #Splits 20% data to test set
The code splits the entire dataset to 80% train and 20% test data
Try using setAttribute on the result:
result.setAttribute("class","red");
Same Problem I had... I was writing all the script in a seperate file and was adding it through tag into the end of the HTML file after body tag. After moving the the tag inside the body tag it works fine. before :
</body>
<script>require('../script/viewLog.js')</script>
after :
<script>require('../script/viewLog.js')</script>
</body>
Came across this problem while upgrading projects across eclipse versions. For e.g. junits running well in Mars2.0 did not run on Neon. The following worked for me.
Right click on the project in solution explorer or class view window --> "View" --> "View Class Diagram"
You could upload via $resource
by assigning data to params attribute of resource actions
like so:
$scope.uploadFile = function(files) {
var fdata = new FormData();
fdata.append("file", files[0]);
$resource('api/post/:id', { id: "@id" }, {
postWithFile: {
method: "POST",
data: fdata,
transformRequest: angular.identity,
headers: { 'Content-Type': undefined }
}
}).postWithFile(fdata).$promise.then(function(response){
//successful
},function(error){
//error
});
};
firstDigit = number/((int)(pow(10,(int)log(number))));
This should get your first digit using math instead of strings.
In your example log(543) = 2.73 which casted to an int is 2. pow(10, 2) = 100 543/100 = 5.43 but since it's an int it gets truncated to 5
This worked for me.
git reset --hard ORIG_HEAD
Undo a merge or pull:
$ git pull (1)
Auto-merging nitfol
CONFLICT (content): Merge conflict in nitfol
Automatic merge failed; fix conflicts and then commit the result.
$ git reset --hard (2)
$ git pull . topic/branch (3)
Updating from 41223... to 13134...
Fast-forward
$ git reset --hard ORIG_HEAD (4)
Checkout this: HEAD and ORIG_HEAD in Git for more.
You can do this by changing the php.ini file and add the following
display_errors = on
display_startup_errors = on
OR you can also use the following code as this always works for me
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
Reading the answers - including the accepted one I'd like to point out the security implications of passing a path directly to readfile via GET.
It may seem obvious to some but some may simply copy/paste this code:
<?php
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=".$_GET['path']);
readfile($_GET['path']);
?>
So what happens if I pass something like '/path/to/fileWithSecrets' to this script? The given script will happily send any file the webserver-user has access to.
Please refer to this discussion for information how to prevent this: How do I make sure a file path is within a given subdirectory?
A speedy and succinct tidyverse
solution:
(more than twice as fast as Base R's read.csv
)
tbl <-
list.files(pattern = "*.csv") %>%
map_df(~read_csv(.))
and data.table's fread()
can even cut those load times by half again. (for 1/4 the Base R times)
library(data.table)
tbl_fread <-
list.files(pattern = "*.csv") %>%
map_df(~fread(.))
The stringsAsFactors = FALSE
argument keeps the dataframe factor free, (and as marbel points out, is the default setting for fread
)
If the typecasting is being cheeky, you can force all the columns to be as characters with the col_types
argument.
tbl <-
list.files(pattern = "*.csv") %>%
map_df(~read_csv(., col_types = cols(.default = "c")))
If you are wanting to dip into subdirectories to construct your list of files to eventually bind, then be sure to include the path name, as well as register the files with their full names in your list. This will allow the binding work to go on outside of the current directory. (Thinking of the full pathnames as operating like passports to allow movement back across directory 'borders'.)
tbl <-
list.files(path = "./subdirectory/",
pattern = "*.csv",
full.names = T) %>%
map_df(~read_csv(., col_types = cols(.default = "c")))
As Hadley describes here (about halfway down):
map_df(x, f)
is effectively the same asdo.call("rbind", lapply(x, f))
....
Bonus Feature - adding filenames to the records per Niks feature request in comments below:
* Add original filename
to each record.
Code explained: make a function to append the filename to each record during the initial reading of the tables. Then use that function instead of the simple read_csv()
function.
read_plus <- function(flnm) {
read_csv(flnm) %>%
mutate(filename = flnm)
}
tbl_with_sources <-
list.files(pattern = "*.csv",
full.names = T) %>%
map_df(~read_plus(.))
(The typecasting and subdirectory handling approaches can also be handled inside the read_plus()
function in the same manner as illustrated in the second and third variants suggested above.)

The base R results are better for the smallest use cases where the overhead of bringing the C libraries of purrr and dplyr to bear outweigh the performance gains that are observed when performing larger scale processing tasks.
if you want to run your own tests you may find this bash script helpful.
for ((i=1; i<=$2; i++)); do
cp "$1" "${1:0:8}_${i}.csv";
done
bash what_you_name_this_script.sh "fileName_you_want_copied" 100
will create 100 copies of your file sequentially numbered (after the initial 8 characters of the filename and an underscore).
With special thanks to:
map_df()
here.fread()
. (I need to study up on data.table
.)The C# compiler infers the true type of the var
variable at compile time. There's no difference in the generated IL.
Well, after doing more research on this topic I ended up using following solution for targeting IE 10+. As IE10&11 are the only browsers which support the -ms-high-contrast media query, that is a good option without any JS:
@media screen and (-ms-high-contrast: active), screen and (-ms-high-contrast: none) {
/* IE10+ specific styles go here */
}
Works perfectly.
After deep investigation of the problem I found that error occurs selecting DIV elements that were added for Bootstrap only. Chrome browser removes such DIVS and the error occurs. It is enough to step down and select real element for fixing an error. For example, my modal dialog has structure:
<div class="modal-content" uib-modal-transclude="">
<div class="modal-header">
...
</div>
<div class="modal-body">
<form class="form-horizontal ...">
...
</form>
<div>
<div>
Selecting div class="modal-body" generates an error, selecting form ... works as it would.
#!/usr/bin/env ruby
# current dir should be drawable-hdpi/ etc

system "ln -s #{f} #{f.gsub('/', '_')}" if f.include?("/")
}
By using System.exit(0); you would close the entire process. Is that what you wanted or did you intend to close only the GUI window and allow the process to continue running?
The quickest, easiest and most robust way to simply close a JFrame or JPanel with the click of a JButton is to add an actionListener to the JButton which will execute the line of code below when the JButton is clicked:
this.dispose();
If you are using the NetBeans GUI designer, the easiest way to add this actionListener is to enter the GUI editor window and double click the JButton component. Doing this will automatically create an actionListener and actionEvent, which can be modified manually by you.
First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.
For example,
> z <- factor(letters[c(3, 2, 3, 4)])
# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d
# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"
here, z
has 4 elements.
The index is 2, 1, 2, 3
in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.
Then, as.numeric
converts simply the index part of factor into numeric.
as.character
handles the index and levels, and generates character vector expressed by its level.
?as.numeric
says that Factors are handled by the default method.

While looking at your code, the only thing I see wrong, is when you try to load the second database:
$DB2=$this->load->database($config);
When you want to retrieve the database object, you have to pass TRUE in the second argument.
From the Codeigniter User Guide:
By setting the second parameter to TRUE (boolean) the function will return the database object.
So, your code should instead be:
$DB2=$this->load->database($config, TRUE);
That will make it work.
I am just beginning to dig deeper into git, so not sure if I understand correctly, but I think the correct answer to the OP's question is that you can run git log --all
with a format specification like this: git log --all --pretty=format:'%h: %s %d'
. This marks the current checked out version as (HEAD)
and you can just grab the next one from the list.
BTW, add an alias like this to your .gitconfig
with a slightly better format and you can run git hist --all
:
hist = log --pretty=format:\"%h %ai | %s%d [%an]\" --graph
Regarding the relative versions, I found this post, but it only talks about older versions, there is probably nothing to refer to the newer versions.
Use this:
@Override
public void onBackPressed() {
int fragments = getFragmentManager().getBackStackEntryCount();
if (fragments == 1) {
finish();
}
super.onBackPressed();
}
You don't need jQuery for this. You can use JavaScript's .childNodes.length
.
Just make sure to subtract 1 if you don't want to include the default text node (which is empty by default). Thus, you'd use the following:
var count = elem.childNodes.length - 1;
I recommend you to look at the adbroker package of the oVirt project. It uses Spring-Ldap and the Krb5 JAAS Login module (with GSSAPI) in order to authenticate using Kerberos against Ldap servers (Active-Directory, ipa, rhds, Tivoli-DS). Look for the code at engine\backend\manager\modules\bll\src\main\java\org\ovirt\engine\core\bll\adbroker
You can use git to clone the repository or browse using the gerrit link
Just add the following in your connection string:
MultipleActiveResultSets=True;
The database.yml
is a file that is created with new rails applications in /config
and defines the database configurations that your application will use in different environments. Read this for details.
Example database.yml:

pool: 5
timeout: 5000
test:
adapter: sqlite3
database: db/test.sqlite3
pool: 5
timeout: 5000

password: your_pass
socket: /tmp/mysql.sock
host: your_db_ip #defaults to 127.0.0.1
port: 3306
SciPy's imresize()
method was another resize method, but it will be removed starting with SciPy v 1.3.0 . SciPy refers to PIL image resize method: Image.resize(size, resample=0)
size – The requested size in pixels, as a 2-tuple: (width, height).
resample – An optional resampling filter. This can be one of PIL.Image.NEAREST (use nearest neighbour), PIL.Image.BILINEAR (linear interpolation), PIL.Image.BICUBIC (cubic spline interpolation), or PIL.Image.LANCZOS (a high-quality downsampling filter). If omitted, or if the image has mode “1” or “P”, it is set PIL.Image.NEAREST.
Link here: https://pillow.readthedocs.io/en/3.1.x/reference/Image.html#PIL.Image.Image.resize
I thought that the most intuitive single file upload process was to replace the previous file upon a new entry.
$(".drop-image").dropzone({
url: '/cart?upload-engraving=true',
maxFiles: 1,
maxfilesexceeded: function(file) {
this.removeAllFiles();
this.addFile(file);
}
})
"I mean the number of digits in an integer, i.e. "123" has a length of 3"
int i = 123;
// the "length" of 0 is 1:
int len = 1;
// and for numbers greater than 0:
if (i > 0) {
// we count how many times it can be divided by 10:
// (how many times we can cut off the last digit until we end up with 0)
for (len = 0; i > 0; len++) {

}
}
// and that's our "length":
std::cout << len;

Step1: run command killall -9 node
For windows users, run:
taskkill /im node.exe
Run
taskkill /f /im node.exe
if the process still persists.
Step2: run command npm start --reset-cache
Step3: run command react-native run-ios
OR react-native run-android
Depends on what you want to do. If you want to use the two arguments as input files, you can just pass them in and then use <>
to read their contents.
If they have a different meaning, you can use GetOpt::Std
and GetOpt::Long
to process them easily. GetOpt::Std
supports only single-character switches and GetOpt::Long
is much more flexible. From GetOpt::Long
:
use Getopt::Long;
my $data = "file.dat";
my $length = 24;
my $verbose;
$result = GetOptions ("length=i" => \$length, # numeric
"file=s" => \$data, # string
"verbose" => \$verbose); # flag
Alternatively, @ARGV
is a special variable that contains all the command line arguments. $ARGV[0]
is the first (ie. "string1"
in your case) and $ARGV[1]
is the second argument. You don't need a special module to access @ARGV
.
You can also use the setProperty method like below
document.getElementById('divName').style.setProperty("top", "100px");
I solved my problem by running below command
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
You can also use PreviewKeyDown in WPF:
<TextBox PreviewKeyDown="EnterClicked" />
or in C#:
myTextBox.PreviewKeyDown += EnterClicked;
And then in the attached class:
void EnterClicked(object sender, KeyEventArgs e) {
if(e.Key == Key.Return) {
DoSomething();
e.Handled = true;
}
}
Just to clarify, this is correct.
Cannot convert 'NodeList' to 'HTMLScriptElement[]'
as a NodeList
is not an actual array (e.g. it doesn't contain .forEach
, .slice
, .push
, etc...).
Thus if it did convert to HTMLScriptElement[]
in the type system, you'd get no type errors if you tried to call Array.prototype
members on it at compile time, but it would fail at run time.
since async ajax is deprecated try using nested async functions with a Promise. There may be syntax errors.
async function fetch_my_data(_url, _dat) {
async function promised_fetch(_url, _dat) {
return new Promise((resolve, reject) => {
$.ajax({
url: _url,
data: _dat,
type: 'POST',
success: (response) => {
resolve(JSON.parse(response));
},
error: (response) => {
reject(response);
}
});
});
}
var _data = await promised_fetch(_url, _dat);
return _data;
}
var _my_data = fetch_my_data('server.php', 'get_my_data=1');
This is just a modification of lunicon's answer (https://stackoverflow.com/a/24387115/3519572) if you want to replace one namespace for another during parsing. And if you want to see what exactly is going on, just uncomment the output lines and set a breakpoint.

In order to rename a table in a different schema, try:
ALTER TABLE owner.mytable RENAME TO othertable;
The rename command (as in "rename mytable to othertable
") only supports renaming a table in the same schema.

for(let i of args){
console.log(i)
}

For Angular 8 or posterior @ViewChild have an additional parameter called opts, which have two properties: read and static, read is optional. You can use it like so:
// ...
@ViewChild('mydiv', { static: false }) public mydiv: ElementRef;
constructor() {
// ...
<div #mydiv></div>
NOTE: Static: false is not required anymore in Angular 9. (just { static: true }
when you are going to use that variable inside ngOnInit)
Private variables in python is more or less a hack: the interpreter intentionally renames the variable.
class A:
def __init__(self):
self.__var = 123
def printVar(self):
print self.__var
Now, if you try to access __var
outside the class definition, it will fail:
>>>x = A()
>>>x.__var # this will return error: "A has no attribute __var"
>>>x.printVar() # this gives back 123
But you can easily get away with this:
>>>x.__dict__ # this will show everything that is contained in object x
# which in this case is something like {'_A__var' : 123}
>>>x._A__var = 456 # you now know the masked name of private variables
>>>x.printVar() # this gives back 456
You probably know that methods in OOP are invoked like this: x.printVar() => A.printVar(x)
, if A.printVar()
can access some field in x
, this field can also be accessed outside A.printVar()
...after all, functions are created for reusability, there is no special power given to the statements inside.
The game is different when there is a compiler involved (privacy is a compiler level concept). It know about class definition with access control modifiers so it can error out if the rules are not being followed at compile time
Most of these are great answers, but I feel that they are leaving out one inevitable aspect of web-development which is the on-going page update. What if you want to come and add content to this div? Should you always come to adjust the div min-height? Well, whilst trying to answer these two questions, I tried out the following code instead:
.box-centerside {
background: url("../images/greybox-center-bg1.jpg") repeat-x scroll center top transparent;
float: left;
height: auto; /* adjusts height container element according to content */
width: 260px;
}
furthermore, just for a sort of bonus , if you have elements around this div with properties like position: relative;
, they would consequently stack on top of this div, because it has property float: left;
To avoid such stacking, I tried the following code:
.parent {
display: grid;
grid-template-columns: repeat(3, 1fr); /* number depends on how many columns you want for a particular screen width. */
height: auto; /* adjusts height container element according to content */
}
.box-centerside {
background: url("../images/greybox-center-bg1.jpg") repeat-x scroll center top transparent;
height: auto; /* adjusts height container element according to content */
width: 100%;
}
.sibling 1 {
/* Code here */
}
.sibling 2 {
/* Code here */
}
My opinion is that, I find this grid method of displaying more fitting for a responsive website. Otherwise, there are many ways of achieving the same goals; But some of the important goals of programming are to make coding simpler and more readable as well as easier to understand.
Here's my anwser, and I won't promse to be an expert, but I've found pointers to be great in one of my libraries I'm trying to write. In this library (It's a graphics API with OpenGL:-)) you can create a triangle with vertex objects passed into them. The draw method takes these triangle objects, and well.. draws them based on the vertex objects i created. Well, its ok.
But, what if i change a vertex coordinate? Move it or something with moveX() in the vertex class? Well, ok, now i have to update the triangle, adding more methods and performance is being wasted because i have to update the triangle every time a vertex moves. Still not a big deal, but it's not that great.
Now, what if i have a mesh with tons of vertices and tons of triangles, and the mesh is rotateing, and moveing, and such. I'll have to update every triangle that uses these vertices, and probably every triangle in the scene because i wouldn't know which ones use which vertices. That's hugely computer intensive, and if I have several meshes ontop of a landscape, oh god! I'm in trouble, because im updateing every triangle almost every frame because these vertices are changing al the time!
With pointers, you don't have to update the triangles.
If I had three *Vertex objects per triangle class, not only am i saving room because a zillion triangles don't have three vertex objects which are large themselves, but also these pointers will always point to the Vertices they are meant to, no matter how often the vertices change. Since the pointers still point to the same vertex, the triangles don't change, and the update process is easier to handle. If I confused you, I wouldn't doubt it, I don't pretend to be an expert, just throwing my two cents into the discussion.
either ceil and floor should give the same out out put
Math.ceil(x.y) == Math.floor(x.y)
or simply check for equality with double value
x.y == Math.ceil(x.y)
x.y == Math.floor(x.y)
or
Math.round(x.y) == x.y
Here is exp.
$date_search_strtotime = strtotime(date("Y-m-d"));
echo 'Now strtotime date : '.$date_search_strtotime;
echo '<br>';
echo 'Now date from strtotime : '.date('Y-m-d',$date_search_strtotime);
Your example wasn't working because you are trying to add 1 to a string that looks like this: "1.html". That will just get you this "1.html1" which is not what you want. You have to isolate the numeric part of the string and then convert it to an actual number before you can do math on it. After getting it to an actual number, you can then increase its value and then combine it back with the rest of the string.
You can use a custom replace function like this to isolate the various pieces of the original URL and replace the number with an incremented number:
function nextImage() {
return(window.location.href.replace(/(\d+)(\.html)$/, function(str, p1, p2) {
return((Number(p1) + 1) + p2);
}));
}
You can then call it like this:
window.location.href = nextImage();
Demo here: http://jsfiddle.net/jfriend00/3VPEq/
This will work for any URL that ends in some series of digits followed by .html and if you needed a slightly different URL form, you could just tweak the regular expression.
Try this, but you can adjust frame size with bounds and edit title.
package co.form.Try;
import javax.swing.JFrame;
public class Form {
public static void main(String[] args) {
JFrame obj =new JFrame();
obj.setBounds(10,10,700,600);
obj.setTitle("Application Form");
obj.setResizable(false);
obj.setVisible(true);
obj.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
You want the non-locale-aware floatval
function:
float floatval ( mixed $var ) - Gets the float value of a string.
Example:
$string = '122.34343The';
$float = floatval($string);
echo $float; // 122.34343
@tableName
Table variables are alive for duration of the script running only i.e. they are only session level objects.
To test this, open two query editor windows under sql server management studio, and create table variables with same name but different structures. You will get an idea. The @tableName
object is thus temporary and used for our internal processing of data, and it doesn't contribute to the actual database structure.
There is another type of table object which can be created for temporary use. They are #tableName
objects declared like similar create statement for physical tables:
Create table #test (Id int, Name varchar(50))
This table object is created and stored in temp database. Unlike the first one, this object is more useful, can store large data and takes part in transactions etc. These tables are alive till the connection is open. You have to drop the created object by following script before re-creating it.
IF OBJECT_ID('tempdb..#test') IS NOT NULL
DROP TABLE #test
Hope this makes sense !
</script>
has to be broken up because otherwise it would end the enclosing <script></script>
block too early. Really it should be split between the <
and the /
, because a script block is supposed (according to SGML) to be terminated by any end-tag open (ETAGO) sequence (i.e. </
):
Although the STYLE and SCRIPT elements use CDATA for their data model, for these elements, CDATA must be handled differently by user agents. Markup and entities must be treated as raw text and passed to the application as is. The first occurrence of the character sequence "
</
" (end-tag open delimiter) is treated as terminating the end of the element's content. In valid documents, this would be the end tag for the element.
However in practice browsers only end parsing a CDATA script block on an actual </script>
close-tag.
In XHTML there is no such special handling for script blocks, so any <
(or &
) character inside them must be &escaped;
like in any other element. However then browsers that are parsing XHTML as old-school HTML will get confused. There are workarounds involving CDATA blocks, but it's easiest simply to avoid using these characters unescaped. A better way of writing a script element from script that works on either type of parser would be:
<script type="text/javascript">
document.write('\x3Cscript type="text/javascript" src="foo.js">\x3C/script>');
</script>
I agree with what Joachim Sauer said, not possible to know (the variable type! not value type!) unless your variable is a class attribute (and you would have to retrieve class fields, get the right field by name...)
Actually for me it's totally impossible that any a.xxx().yyy()
method give you the right answer since the answer would be different on the exact same object, according to the context in which you call this method...
As teehoo said, if you know at compile a defined list of types to test you can use instanceof but you will also get subclasses returning true...
One possible solution would also be to inspire yourself from the implementation of java.lang.reflect.Field
and create your own Field
class, and then declare all your local variables as this custom Field
implementation... but you'd better find another solution, i really wonder why you need the variable type, and not just the value type?
You can use inner divs to set the margin.
<div style="display: table-cell;">
<div style="margin:5px;background-color: red;">1</div>
</div>
<div style="display: table-cell; ">
<div style="margin:5px;background-color: green;">1</div>
</div>
Another way:
var := coalesce (var, 5);
COALESCE is the ANSI equivalent (more or less) of Oracle's NVL function.
You created the UIButton
is added the ViewController
, The following instance method to change UIFont
, tintColor
and TextColor
of the UIButton
Objective-C
buttonName.titleLabel.font = [UIFont fontWithName:@"LuzSans-Book" size:15];
buttonName.tintColor = [UIColor purpleColor];
[buttonName setTitleColor:[UIColor purpleColor] forState:UIControlStateNormal];
Swift
buttonName.titleLabel.font = UIFont(name: "LuzSans-Book", size: 15)
buttonName.tintColor = UIColor.purpleColor()
buttonName.setTitleColor(UIColor.purpleColor(), forState: .Normal)
Swift3
buttonName.titleLabel?.font = UIFont(name: "LuzSans-Book", size: 15)
buttonName.tintColor = UIColor.purple
buttonName.setTitleColor(UIColor.purple, for: .normal)
SetTimeout is used to make your set of code to execute after a specified time period so for your requirements its better to use setInterval because that will call your function every time at a specified time interval.
Another way to do this is described below.
First, turn on iterative calculations on under File - Options - Formulas - Enable Iterative Calculation
. Then set maximum iterations to 1000.
After doing this, use the following formula.
=If(D55="","",IF(C55="",NOW(),C55))
Once anything is typed into cell D55
(for this example) then C55
populates today's date and/or time depending on the cell format. This date/time will not change again even if new data is entered into cell C55 so it shows the date/time that the data was entered originally.
This is a circular reference formula so you will get a warning about it every time you open the workbook. Regardless, the formula works and is easy to use anywhere you would like in the worksheet.
Here is a solution using the Shapely library. Shapely is often used for GIS work, but is built to be useful for computational geometry. I changed your inputs from lists to tuples.
# Given these endpoints
#line 1
A = (X, Y)
B = (X, Y)
#line 2
C = (X, Y)
D = (X, Y)
# Compute this:
point_of_intersection = (X, Y)
import shapely
from shapely.geometry import LineString, Point
line1 = LineString([A, B])
line2 = LineString([C, D])
int_pt = line1.intersection(line2)
point_of_intersection = int_pt.x, int_pt.y
print(point_of_intersection)
This problems gave me great headache when i tried to use reverse for generating activation link and send it via email of course. So i think from tests.py it will be same. The correct way to do this is following:
from django.test import Client
from django.core.urlresolvers import reverse
#app name - name of the app where the url is defined
client= Client()
response = client.get(reverse('app_name:edit_project', project_id=4))
OR
.section:hover > div {
background-color: #0CF;
}
NOTE Parent element state can only affect a child's element state so you can use:
.image:hover + .layer {
background-color: #0CF;
}
.image:hover {
background-color: #0CF;
}
but you can not use
.layer:hover + .image {
background-color: #0CF;
}
encode function can help you here, encode returns an encoded version of the string
In [44]: str = "ABCD"
In [45]: [elem.encode("hex") for elem in str]
Out[45]: ['41', '42', '43', '44']
or you can use array module
In [49]: import array
In [50]: print array.array('B', "ABCD")
array('B', [65, 66, 67, 68])
You could use box-shadow
, possibly:
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
box-shadow: inset 0 0 10px #0f0;
}
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
box-shadow: inset 0 0 10px #0f0;
}
_x000D_
<div id="something"></div>
_x000D_
This has the advantage that it will overlay the background-image of the div
, but it is, of course, blurred (as you'd expect from the box-shadow
property). To build up the density
of the shadow you can add additional shadows of course:
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
box-shadow: inset 0 0 20px #0f0, inset 0 0 20px #0f0, inset 0 0 20px #0f0;
}
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
box-shadow: inset 0 0 20px #0f0, inset 0 0 20px #0f0, inset 0 0 20px #0f0;
}
_x000D_
<div id="something"></div>
_x000D_
Edited because I realised that I'm an idiot, and forgot to offer the simplest solution first, which is using an otherwise-empty child element to apply the borders over the background:
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
padding: 0;
position: relative;
}
#something div {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
border: 10px solid rgba(0, 255, 0, 0.6);
}
_x000D_
<div id="something">
<div></div>
</div>
_x000D_
Edited after @CoryDanielson's comment, below:
jsfiddle.net/dPcDu/2 you can add a 4th px parameter for the
box-shadow
that does the spread and will more easily reflect his images.
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
box-shadow: inset 0 0 0 10px rgba(0, 255, 0, 0.5);
}
_x000D_
<div id="something"></div>
_x000D_

Best practice for RESTful API design is that path params are used to identify a specific resource or resources, while query parameters are used to sort/filter those resources.
Here's an example. Suppose you are implementing RESTful API endpoints for an entity called Car. You would structure your endpoints like this:
GET /cars
GET /cars/:id
POST /cars
PUT /cars/:id
DELETE /cars/:id
This way you are only using path parameters when you are specifying which resource to fetch, but this does not sort/filter the resources in any way.
Now suppose you wanted to add the capability to filter the cars by color in your GET requests. Because color is not a resource (it is a property of a resource), you could add a query parameter that does this. You would add that query parameter to your GET /cars
request like this:
GET /cars?color=blue
This endpoint would be implemented so that only blue cars would be returned.
As far as syntax is concerned, your URL names should be all lowercase. If you have an entity name that is generally two words in English, you would use a hyphen to separate the words, not camel case.
Ex. /two-words
In ASP.NET there is similar object, you can use Caching Portions in WebFormsUserControls in order to cache objects of a page for a period of time and save server resources. This is also known as fragment caching.
If you include this code to top of your user control, a version of the control stored in the output cache for 150 seconds.
You can create your own control that would contain expire header for a specific resource you want.
<%@ OutputCache Duration="150" VaryByParam="None" %>

The basic one, ask tasklist to filter its output and only show the indicated process id information
tasklist /fi "pid eq 4444"
To only get the process name, the line must be splitted
for /f "delims=," %%a in ('
tasklist /fi "pid eq 4444" /nh /fo:csv
') do echo %%~a
In this case, the list of processes is retrieved without headers (/nh
) in csv format (/fo:csv
). The commas are used as token delimiters and the first token in the line is the image name
note: In some windows versions (one of them, my case, is the spanish windows xp version), the pid filter in the tasklist does not work. In this case, the filter over the list of processes must be done out of the command
for /f "delims=," %%a in ('
tasklist /fo:csv /nh ^| findstr /b /r /c:"[^,]*,\"4444\","
') do echo %%~a
This will generate the task list and filter it searching for the process id in the second column of the csv output.
edited: alternatively, you can suppose what has been made by the team that translated the OS to spanish. I don't know what can happen in other locales.
tasklist /fi "idp eq 4444"
You can use Postman a plugin for chrome. It gives the ability to choose the authentication type you need for each of the requests. In that menu you can configure user and password. Postman will automatically translate the config to a authentication header that will be sent with your request.
An example of bootstrapping is in some web frameworks. You call index.php (the bootstrapper), and then it loads the frameworks helpers, models, configuration, and then loads the controller and passes off control to it.
As you can see, it's a simple file that starts a large process.

You should loop through all tables and test if table.Rows.Count is 0
bool IsEmpty(DataSet dataSet)
{
foreach(DataTable table in dataSet.Tables)
if (table.Rows.Count != 0) return false;
return true;
}
Update: Since a DataTable could contain deleted rows RowState = Deleted
, depending on what you want to achive, it could be a good idea to check the DefaultView
instead (which does not contain deleted rows).
bool IsEmpty(DataSet dataSet)
{
return !dataSet.Tables.Cast<DataTable>().Any(x => x.DefaultView.Count > 0);

Method I used to split first_name into first_name and last_name when the data arrived all in the first_name field. This will put only the last word in the last name field, so "john phillips sousa" will be "john phillips" first name and "sousa" last name. It also avoids overwriting any records that have been fixed already.
set last_name=trim(SUBSTRING_INDEX(first_name, ' ', -1)), first_name=trim(SUBSTRING(first_name,1,length(first_name) - length(SUBSTRING_INDEX(first_name, ' ', -1)))) where list_id='$List_ID' and length(first_name)>0 and length(trim(last_name))=0
simply try this 'listBox' is your list and 'yu' is a veriable to which the value on index 0 will be assigned
string yu = listBox1.Items[0].ToString();
MessageBox.Show(yu);
I find that I run into Net::HTTP and Net::FTP problems like this periodically, and when I do, surrounding the call with a timeout() makes all of those issues vanish. So where this will occasionally hang for 3 minutes or so and then raise an EOFError:
res = Net::HTTP.post_form(uri, args)
This always fixes it for me:
res = timeout(120) { Net::HTTP.post_form(uri, args) }
As per the DOM structure you can use below code:
var x = document.getElementById('mySelect');
var txt = "";
var val = "";
for (var i = 0; i < x.length; i++) {
txt +=x[i].text + ",";
val +=x[i].value + ",";
}
If you are not targeting 2.x versions you can set your minimum sdk version of 4.x and then create project. Appcompat V7 lib wont be created.

You can do this:
alert([
"afshin",
"saeed",
"larry",
"sasha",
"boby",
"jhon",
"anna",
// ...
].includes(varName)? 'Hey' : 'Default case')
or just a single line of code:
alert(["afshin", "saeed", "larry",...].includes(varName)? 'Hey' : 'Default case')

I strongly recommend you to use [DiffUtil.ItemCallback][1]
to handle the change in RecyclerView.Adapter
fun setData(data: List<T>) {
val calculateDiff = DiffUtil.calculateDiff(DiffUtilCallback(items, data))
items.clear()
items += data
calculateDiff.dispatchUpdatesTo(this)
}
under the hood it handles most of the things with AdapterListUpdateCallback
:
/**
* ListUpdateCallback that dispatches update events to the given adapter.
*
* @see DiffUtil.DiffResult#dispatchUpdatesTo(RecyclerView.Adapter)
*/
public final class AdapterListUpdateCallback implements ListUpdateCallback {
@NonNull
private final RecyclerView.Adapter mAdapter;
/**
* Creates an AdapterListUpdateCallback that will dispatch update events to the given adapter.
*
* @param adapter The Adapter to send updates to.
*/
public AdapterListUpdateCallback(@NonNull RecyclerView.Adapter adapter) {
mAdapter = adapter;
}
/** {@inheritDoc} */
@Override
public void onInserted(int position, int count) {
mAdapter.notifyItemRangeInserted(position, count);
}
/** {@inheritDoc} */
@Override
public void onRemoved(int position, int count) {
mAdapter.notifyItemRangeRemoved(position, count);
}
/** {@inheritDoc} */
@Override
public void onMoved(int fromPosition, int toPosition) {
mAdapter.notifyItemMoved(fromPosition, toPosition);
}
/** {@inheritDoc} */
@Override
public void onChanged(int position, int count, Object payload) {
mAdapter.notifyItemRangeChanged(position, count, payload);
}
}
I think that it is better (for my expirience) to use: :first-of-type
, :nth-of-type()
, :last-of-type
. It can be done whit a little changing of rules, but I was able to do much more than whit *-of-type
, than *-child
selectors.
To read a file from internal storage:
Call openFileInput() and pass it the name of the file to read. This returns a FileInputStream. Read bytes from the file with read(). Then close the stream with close().
code::
StringBuilder sb = new StringBuilder();
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
is.close();
} catch(OutOfMemoryError om){
om.printStackTrace();
} catch(Exception ex){
ex.printStackTrace();
}
String result = sb.toString();
This is just about the most bizarre query I've ever written, but I'm pretty sure it gets the "last 5" rows from a table without ordering:
select *
from issues
where issueid not in (
select top (
(select count(*) from issues) - 5
) issueid
from issues
)
Note that this makes use of SQL Server 2005's ability to pass a value into the "top" clause - it doesn't work on SQL Server 2000.
I learnt a easy way from code example of http://tutorial.symblog.co.uk/
1) notice the ZendeskBlueFormBundle and file location
# myproject/app/config/config.yml
imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: @ZendeskBlueFormBundle/Resources/config/config.yml }
framework:
2) notice Zendesk_BlueForm.emails.contact_email and file location
# myproject/src/Zendesk/BlueFormBundle/Resources/config/config.yml
parameters:
# Zendesk contact email address
Zendesk_BlueForm.emails.contact_email: [email protected]
3) notice how i get it in $client and file location of controller
# myproject/src/Zendesk/BlueFormBundle/Controller/PageController.php
public function blueFormAction($name, $arg1, $arg2, $arg3, Request $request)
{
$client = new ZendeskAPI($this->container->getParameter("Zendesk_BlueForm.emails.contact_email"));
...
}
If you want to change the external terminal to the new windows terminal, here's how.
if you have array of object and you would like to deserialize them in compoent
get example() { this.arrayOfObject.map(i => JSON.stringify (i) ) };
then in template
<ul>
<li *ngFor="obj of example">{{obj}}</li>
</ul>
if you are using Pycharm navigate settings > Project:name > Project interpreter just search the module by name(in this case OpenCV-python) and install it. worked for me
Some of the above solutions worked to resolve some of my errors... it seems that after a while update connections just get corrupted and there is no silver-bullet. Managing updates through the marketplace (Help > Marketplace > 'show updates') allowed me to narrow down the packages with failed dependencies.
Here's what I tried (taken from posts above):
I was still left with some Mylyn wikitext errors despite trying the suggestions here
Eclipse IDE for JavaScript and Web Developers
Version: 2019-09 R (4.13.0) Build id: 20190917-1200
Make a 2-dimensional array that corresponds to the cells in your final image, called say heatmap_cells
and instantiate it as all zeroes.
Choose two scaling factors that define the difference between each array element in real units, for each dimension, say x_scale
and y_scale
. Choose these such that all your datapoints will fall within the bounds of the heatmap array.
For each raw datapoint with x_value
and y_value
:
heatmap_cells[floor(x_value/x_scale),floor(y_value/y_scale)]+=1
another solution:
add src/myproject
to $GOPATH.
Then import "mylib"
will compile.
As pointed out in the comments, you cannot catch an exception that's not thrown by the code within your try
block. Try changing your code to:
try{
Integer.parseInt(args[i-1]); // this only throws a NumberFormatException
}
catch(NumberFormatException e){
throw new MojException("Bledne dane");
}
Always check the documentation to see what exceptions are thrown by each method. You may also wish to read up on the subject of checked vs unchecked exceptions before that causes you any confusion in the future.
Here's how to do it inside ViewModel
and FusedLocationProviderClient
, code in Kotlin
locationClient.lastLocation.addOnSuccessListener { location: Location? ->
location?.let {
val position = CameraPosition.Builder()
.target(LatLng(it.latitude, it.longitude))
.zoom(15.0f)
.build()
map.animateCamera(CameraUpdateFactory.newCameraPosition(position))
}
}
Try to use JSONP
in your Ajax call. It will bypass the Same Origin Policy.
http://learn.jquery.com/ajax/working-with-jsonp/
Try example
$.ajax({
url: "https://api.dailymotion.com/video/x28j5hv?fields=title",
dataType: "jsonp",
success: function( response ) {
console.log( response ); // server response
}
});
If you don't specify any path and put just the file (Just like you did), the default directory is always the one of your project (It's not inside the "src" folder. It's just inside the folder of your project).
It is easier to compare dates using the java.util.Calendar
.
Here is what you might do:
Calendar toDate = Calendar.getInstance();
Calendar nowDate = Calendar.getInstance();
toDate.set(<set-year>,<set-month>,<set-day>);
if(!toDate.before(nowDate)) {
//display your report
} else {
// don't display the report
}
Here is the code to get the Dimensions of the complete view of the device.
var windowSize = Dimensions.get("window");
Use it like this:
width=windowSize.width,heigth=windowSize.width/0.565
Checkout the branch for which you would like to squash all the commits into one commit. Let's say it's called feature_branch
.
git checkout feature_branch
Do a soft reset of your origin/feature_branch
with your local main
branch (depending on your needs, you can reset with origin/main as well). This will reset all the extra commits in your feature_branch
, but without changing any of your file changes locally.
git reset --soft main
Add all of the changes in your git repo directory, to the new commit that is going to be created. And commit the same with a message.
git add -A && git commit -m "commit message goes here"
You can also use OpenCV's inbuilt functions cv2.hconcat
and cv2.vconcat
which like their names suggest are used to join images horizontally and vertically respectively.
import cv2
img1 = cv2.imread('opencv/lena.jpg')
img2 = cv2.imread('opencv/baboon.jpg')
v_img = cv2.vconcat([img1, img2])
h_img = cv2.hconcat([img1, img2])
cv2.imshow('Horizontal', h_img)
cv2.imshow('Vertical', v_img)
cv2.waitKey(0)
cv2.destroyAllWindows()
Horizontal Concatenation
Vertical Concatenation
It depends on exactly what the requirements are. In particular, how do you want to handle "\r" on its own? Should that count as a line break or not? As an example, how should "a\n\rb" be treated? Is that one very odd line break, one "\n" break and then a rogue "\r", or two separate linebreaks? If "\r" and "\n" can both be linebreaks on their own, why should "\r\n" not be treated as two linebreaks?
Here's some code which I suspect is reasonably efficient.
using System;
using System.Text;
class LineBreaks
{
static void Main()
{
Test("a\nb");
Test("a\nb\r\nc");
Test("a\r\nb\r\nc");
Test("a\rb\nc");
Test("a\r");
Test("a\n");
Test("a\r\n");
}
static void Test(string input)
{
string normalized = NormalizeLineBreaks(input);
string debug = normalized.Replace("\r", "\\r")
.Replace("\n", "\\n");
Console.WriteLine(debug);
}
static string NormalizeLineBreaks(string input)
{
// Allow 10% as a rough guess of how much the string may grow.
// If we're wrong we'll either waste space or have extra copies -
// it will still work
StringBuilder builder = new StringBuilder((int) (input.Length * 1.1));
bool lastWasCR = false;
foreach (char c in input)
{
if (lastWasCR)
{
lastWasCR = false;
if (c == '\n')
{
continue; // Already written \r\n
}
}
switch (c)
{
case '\r':
builder.Append("\r\n");
lastWasCR = true;
break;
case '\n':
builder.Append("\r\n");
break;
default:
builder.Append(c);
break;
}
}
return builder.ToString();
}
}

these answers just had me bouncing back and forth between invalid parameter and missing parameter.
this worked for me , just wrap string variables in quotes...
data: { RecordId: RecordId,
UserId: UId,
UserProfileId: UserProfileId,
ItemType: '"' + ItemType + '"',
FileName: '"' + XmlName + '"'
}
As noted in comments, some of this becomes irrelevant in Java 8, where final
can be implicit. Only an effectively final variable can be used in an anonymous inner class or lambda expression though.
It's basically due to the way Java manages closures.
When you create an instance of an anonymous inner class, any variables which are used within that class have their values copied in via the autogenerated constructor. This avoids the compiler having to autogenerate various extra types to hold the logical state of the "local variables", as for example the C# compiler does... (When C# captures a variable in an anonymous function, it really captures the variable - the closure can update the variable in a way which is seen by the main body of the method, and vice versa.)
As the value has been copied into the instance of the anonymous inner class, it would look odd if the variable could be modified by the rest of the method - you could have code which appeared to be working with an out-of-date variable (because that's effectively what would be happening... you'd be working with a copy taken at a different time). Likewise if you could make changes within the anonymous inner class, developers might expect those changes to be visible within the body of the enclosing method.
Making the variable final removes all these possibilities - as the value can't be changed at all, you don't need to worry about whether such changes will be visible. The only ways to allow the method and the anonymous inner class see each other's changes is to use a mutable type of some description. This could be the enclosing class itself, an array, a mutable wrapper type... anything like that. Basically it's a bit like communicating between one method and another: changes made to the parameters of one method aren't seen by its caller, but changes made to the objects referred to by the parameters are seen.
If you're interested in a more detailed comparison between Java and C# closures, I have an article which goes into it further. I wanted to focus on the Java side in this answer :)
A different approach that I found ugly compared to the classic dict+append, but that works:
df = df.T
df[0] = ['1/1/2013', 'Smith','test',123]
df = df.T
df
Out[6]:
Date Name Action ID
0 1/1/2013 Smith test 123
In Python, you can't just embed arbitrary Python expressions into literal strings and have it substitute the value of the string. You need to either:
sys.stderr.write("Usage: " + sys.argv[0])
or
sys.stderr.write("Usage: %s" % sys.argv[0])
Also, you may want to consider using the following syntax of print
(for Python earlier than 3.x):
print >>sys.stderr, "Usage:", sys.argv[0]
Using print
arguably makes the code easier to read. Python automatically adds a space between arguments to the print
statement, so there will be one space after the colon in the above example.
In Python 3.x, you would use the print
function:
print("Usage:", sys.argv[0], file=sys.stderr)
Finally, in Python 2.6 and later you can use .format
:
print >>sys.stderr, "Usage: {0}".format(sys.argv[0])
