How to show multiline text in a table cell
Hi I needed to do the same thing! Don't ask why but I was generating a html using python and needed a way to loop through items in a list and have each item take on a row of its own WITHIN A SINGLE CELL of a table.
I found that the br tag worked well for me. For example:
<!DOCTYPE html>
<HTML>
<HEAD>
<TITLE></TITLE>
</HEAD>
<BODY>
<TABLE>
<TR>
<TD>
item 1 <BR>
item 2 <BR>
item 3 <BR>
item 4 <BR>
</TD>
</TR>
</TABLE>
</BODY>
This will produce the output that I wanted.
jQuery each loop in table row
Just a recommendation:
I'd recommend using the DOM table implementation, it's very straight forward and easy to use, you really don't need jQuery for this task.
var table = document.getElementById('tblOne');
var rowLength = table.rows.length;
for(var i=0; i<rowLength; i+=1){
var row = table.rows[i];
//your code goes here, looping over every row.
//cells are accessed as easy
var cellLength = row.cells.length;
for(var y=0; y<cellLength; y+=1){
var cell = row.cells[y];
//do something with every cell here
}
}
jQuery: get parent tr for selected radio button
Try this.
You don't need to prefix attribute name by @ in jQuery selector. Use closest() method to get the closest parent element matching the selector.
$("#MwDataList input[name=selectRadioGroup]:checked").closest('tr');
You can simplify your method like this
function getSelectedRowGuid() {
return GetRowGuid(
$("#MwDataList > input:radio[@name=selectRadioGroup]:checked :parent tr"));
}
closest() - Gets the first element that matches the selector, beginning at the current element and progressing up through the DOM tree.
As a side note, the ids of the elements should be unique on the page so try to avoid having same ids for radio buttons which I can see in your markup. If you are not going to use the ids then just remove it from the markup.
Live search through table rows
Using yckart's answer, I made it to search for the whole table - all td's.
$("#search").keyup(function() {
var value = this.value;
$("table").find("tr").each(function(index) {
if (index === 0) return;
var if_td_has = false; //boolean value to track if td had the entered key
$(this).find('td').each(function () {
if_td_has = if_td_has || $(this).text().indexOf(value) !== -1; //Check if td's text matches key and then use OR to check it for all td's
});
$(this).toggle(if_td_has);
});
});
jQuery append and remove dynamic table row
Change ID to class :
$("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>');
$(".remCF").on('click',function(){
$(this).parent().parent().remove();
});

How to initialize an array in angular2 and typescript
I don't fully understand what you really mean by initializing an array?
Here's an example:
class Environment {
// you can declare private, public and protected variables in constructor signature
constructor(
private id: string,
private name: string
) {
alert( this.id );
}
}
let environments = new Environment('a','b');
// creating and initializing array of Environment objects
let envArr: Array<Environment> = [
new Environment('c','v'),
new Environment('c','v'),
new Environment('g','g'),
new Environment('3','e')
];

How to manage local vs production settings in Django?
I found the responses here very helpful. (Has this been more definitively solved? The last response was a year ago.) After considering all the approaches listed, I came up with a solution that I didn't see listed here.
My criteria were:
- Everything should be in source control. I don't like fiddly bits lying around.
- Ideally, keep settings in one file. I forget things if I'm not looking right at them :)
- No manual edits to deploy. Should be able to test/push/deploy with a single fabric command.
- Avoid leaking development settings into production.
- Keep as close as possible to "standard" (*cough*) Django layout as possible.
I thought switching on the host machine made some sense, but then figured the real issue here is different settings for different environments, and had an aha moment. I put this code at the end of my settings.py file:
try:
os.environ['DJANGO_DEVELOPMENT_SERVER'] # throws error if unset
DEBUG = True
TEMPLATE_DEBUG = True
# This is naive but possible. Could also redeclare full app set to control ordering.
# Note that it requires a list rather than the generated tuple.
INSTALLED_APPS.extend([
'debug_toolbar',
'django_nose',
])
# Production database settings, alternate static/media paths, etc...
except KeyError:
print 'DJANGO_DEVELOPMENT_SERVER environment var not set; using production settings'
This way, the app defaults to production settings, which means you are explicitly "whitelisting" your development environment. It is much safer to forget to set the environment variable locally than if it were the other way around and you forgot to set something in production and let some dev settings be used.
When developing locally, either from the shell or in a .bash_profile or wherever:
$ export DJANGO_DEVELOPMENT_SERVER=yep
(Or if you're developing on Windows, set via the Control Panel or whatever its called these days... Windows always made it so obscure that you could set environment variables.)
With this approach, the dev settings are all in one (standard) place, and simply override the production ones where needed. Any mucking around with development settings should be completely safe to commit to source control with no impact on production.
"for" vs "each" in Ruby
Your first example,
@collection.each do |item|
# do whatever
end
is more idiomatic. While Ruby supports looping constructs like for and while, the block syntax is generally preferred.
Another subtle difference is that any variable you declare within a for loop will be available outside the loop, whereas those within an iterator block are effectively private.
JAVA_HOME directory in Linux
On the Terminal, type:
echo "$JAVA_HOME"
If you are not getting anything, then your environment variable JAVA_HOME has not been set. You can try using "locate java" to try and discover where your installation of Java is located.

How to mock location on device?
If your device is plugged into your computer and your trying to changed send GPS cords Via the Emulator control, it will not work.
This is an EMULATOR control for a reason.
Just set it up to update you on GPS change.
lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
ll = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
onGPSLocationChanged(location);
}
public void onStatusChanged(String provider, int status, Bundle extras) {
bigInfo.setText("Changed "+ status);
}
public void onProviderEnabled(String provider) {
bigInfo.setText("Enabled "+ provider);
}
public void onProviderDisabled(String provider) {
bigInfo.setText("Disabled "+ provider);
}
};
When GPS is updated rewrite the following method to do what you want it to;
public void onGPSLocationChanged(Location location){
if(location != null){
double pLong = location.getLongitude();
double pLat = location.getLatitude();
textLat.setText(Double.toString(pLat));
textLong.setText(Double.toString(pLong));
if(autoSave){
saveGPS();
}
}
}
Dont forget to put these in the manifest
android.permission.ACCESS_FINE_LOCATION
android.permission.ACCESS_MOCK_LOCATION
Regex match entire words only
Using \b can yield surprising results. You would be better off figuring out what separates a word from its definition and incorporating that information into your pattern.

cd into directory without having permission
If it is a directory you own, grant yourself access to it:
chmod u+rx,go-w openfire
That grants you permission to use the directory and the files in it (x) and to list the files that are in it (r); it also denies group and others write permission on the directory, which is usually correct (though sometimes you may want to allow group to create files in your directory - but consider using the sticky bit on the directory if you do).
If it is someone else's directory, you'll probably need some help from the owner to change the permissions so that you can access it (or you'll need help from root to change the permissions for you).
Can pandas automatically recognize dates?
When merging two columns into a single datetime column, the accepted answer generates an error (pandas version 0.20.3), since the columns are sent to the date_parser function separately.
The following works:
def dateparse(d,t):
dt = d + " " + t
return pd.datetime.strptime(dt, '%d/%m/%Y %H:%M:%S')
df = pd.read_csv(infile, parse_dates={'datetime': ['date', 'time']}, date_parser=dateparse)
How to make an input type=button act like a hyperlink and redirect using a get request?
<script type="text/javascript">

url[1]="http://www.codingforums.com.";
url[2]="http://www.w3schools.com";
url[3]="http://www.webmasterworld.com";
window.location=url[num];``
}
// -->
</script>
</head>
<body>
<form action="#">
<div id="container">
<input class="butts" type="button" value="htmlforums" onclick="newPage(0)"/>
<input class="butts" type="button" value="codingforums" onclick="newPage(1)"/>
<input class="butts" type="button" value="w3schools" onclick="newPage(2)"/>
<input class="butts" type="button" value="webmasterworld" onclick="newPage(3)"/>
</div>
</form>
</body>
Here's the other way, it's simpler than the other one.
<input id="inp" type="button" value="Home Page" onclick="location.href='AdminPage.jsp';" />
It's simpler.
How can I make setInterval also work when a tab is inactive in Chrome?
It is quite old question but I encountered the same issue.
If you run your web on chrome, you could read through this post Background Tabs in Chrome 57
.
Basically the interval timer could run if it haven't run out of the timer budget.
The consumption of budget is based on CPU time usage of the task inside timer.
Based on my scenario, I draw video to canvas and transport to WebRTC.
The webrtc video connection would keep updating even the tab is inactive.
However you have to use setInterval instead of requestAnimationFrame.
it is not recommended for UI rendering though.
It would be better to listen visibilityChange event and change render mechenism accordingly.
Besides, you could try @kaan-soral and it should works based on the documentation.

How to check if any flags of a flag combination are set?
In .NET 4 you can use the Enum.HasFlag method :
using System;
[Flags] public enum Pet {
None = 0,
Dog = 1,
Cat = 2,
Bird = 4,
Rabbit = 8,
Other = 16
}
public class Example
{
public static void Main()
{
// Define three families: one without pets, one with dog + cat and one with a dog only
Pet[] petsInFamilies = { Pet.None, Pet.Dog | Pet.Cat, Pet.Dog };
int familiesWithoutPets = 0;
int familiesWithDog = 0;
foreach (Pet petsInFamily in petsInFamilies)
{
// Count families that have no pets.
if (petsInFamily.Equals(Pet.None))
familiesWithoutPets++;
// Of families with pets, count families that have a dog.
else if (petsInFamily.HasFlag(Pet.Dog))
familiesWithDog++;
}
Console.WriteLine("{0} of {1} families in the sample have no pets.",
familiesWithoutPets, petsInFamilies.Length);
Console.WriteLine("{0} of {1} families in the sample have a dog.",
familiesWithDog, petsInFamilies.Length);
}
}
The example displays the following output:
// 1 of 3 families in the sample have no pets.
// 2 of 3 families in the sample have a dog.

If you want to concatenate multiple columns which itself have 4000 bytes, then you can concatenate the XMLAGG output of each column to avoid the SQL limit of 4000 bytes.
For example,
WITH DATA AS
( SELECT 1 id, rpad('a1',4000,'*') col1, rpad('b1',4000,'*') col2 FROM dual
UNION
SELECT 2 id, rpad('a2',4000,'*') col1, rpad('b2',4000,'*') col2 FROM dual
)
SELECT ID,
rtrim(xmlagg(XMLELEMENT(e,col1,',').EXTRACT('//text()') ).GetClobVal(), ',')
||
rtrim(xmlagg(XMLELEMENT(e,col2,',').EXTRACT('//text()') ).GetClobVal(), ',')
AS very_long_text
FROM DATA
GROUP BY ID

How to make an Asynchronous Method return a value?
Perhaps you can try to BeginInvoke a delegate pointing to your method like so:
delegate string SynchOperation(string value);
class Program
{
static void Main(string[] args)
{
BeginTheSynchronousOperation(CallbackOperation, "my value");
Console.ReadLine();
}
static void BeginTheSynchronousOperation(AsyncCallback callback, string value)
{
SynchOperation op = new SynchOperation(SynchronousOperation);
op.BeginInvoke(value, callback, op);
}
static string SynchronousOperation(string value)
{
Thread.Sleep(10000);
return value;
}
static void CallbackOperation(IAsyncResult result)
{
// get your delegate
var ar = result.AsyncState as SynchOperation;
// end invoke and get value
var returned = ar.EndInvoke(result);
Console.WriteLine(returned);
}
}
Then use the value in the method you sent as AsyncCallback to continue..

Is there a null-coalescing (Elvis) operator or safe navigation operator in javascript?
I think the following is equivalent to the safe navigation operator, although a bit longer:
var streetName = user && user.address && user.address.street;
streetName will then be either the value of user.address.street or undefined.
If you want it to default to something else you can combine with the above shortcut or to give:
var streetName = (user && user.address && user.address.street) || "Unknown Street";

For macOS I use two commands together to show information about the processes listening on the machine and process connecting to remote servers. In other words, to check the listening ports and the current (TCP) connections on a host you could use the two following commands together
1. netstat -p tcp -p udp
2. lsof -n -i4TCP -i4UDP
Thought I would add my input, hopefully it can end up helping someone.
Web API Routing - api/{controller}/{action}/{id} "dysfunctions" api/{controller}/{id}
You can solve your problem with help of Attribute routing
Controller
[Route("api/category/{categoryId}")]
public IEnumerable<Order> GetCategoryId(int categoryId) { ... }
URI in jquery
api/category/1
Route Configuration
using System.Web.Http;
namespace WebApplication
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API routes
config.MapHttpAttributeRoutes();
// Other Web API configuration not shown.
}
}
}
and your default routing is working as default convention-based routing
Controller
public string Get(int id)
{
return "object of id id";
}
URI in Jquery
/api/records/1
Route Configuration
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Attribute routing.
config.MapHttpAttributeRoutes();
// Convention-based routing.
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}

Where should I put <script> tags in HTML markup?
The conventional (and widely accepted) answer is "at the bottom", because then the entire DOM will have been loaded before anything can start executing.
There are dissenters, for various reasons, starting with the available practice to intentionally begin execution with a page onload event.
python's re: return True if string contains regex pattern
Here's a function that does what you want:
import re
def is_match(regex, text):
pattern = re.compile(regex, text)
return pattern.search(text) is not None
The regular expression search method returns an object on success and None if the pattern is not found in the string. With that in mind, we return True as long as the search gives us something back.
Examples:
>>> is_match('ba[rzd]', 'foobar')
True
>>> is_match('ba[zrd]', 'foobaz')
True
>>> is_match('ba[zrd]', 'foobad')
True
>>> is_match('ba[zrd]', 'foobam')
False
How to write connection string in web.config file and read from it?
Add reference to add System.Configuration:-

How to set UICollectionViewCell Width and Height programmatically
If you are not using UICollectionViewController, you need to add conformance to it by setting delegates UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout.
extension ViewController: UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout
After that, you have to set a delegate to your collection view that is added to ViewController.
collectionView.delegate = self
collectionView.dataSource = self
And finally, you have to add layout to your collection view:
let collectionLayout = UICollectionViewFlowLayout()
collectionView.collectionViewLayout = collectionLayout
After these steps, you can change size in func:
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize
READ_EXTERNAL_STORAGE permission for Android
In addition of all answers.
You can also specify the minsdk to apply with this annotation
@TargetApi(_apiLevel_)
I used this in order to accept this request even my minsdk is 18. What it does is that the method only runs when device targets "_apilevel_" and upper.
Here's my method:
@TargetApi(23)
void solicitarPermisos(){
if (ContextCompat.checkSelfPermission(this,permiso)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (shouldShowRequestPermissionRationale(
Manifest.permission.READ_EXTERNAL_STORAGE)) {
// Explain to the user why we need to read the contacts
}
requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
1);
// MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
// app-defined int constant that should be quite unique
return;
}
}
Python time measure function
My way of doing it:
from time import time
def printTime(start):
end = time()
duration = end - start
if duration < 60:
return "used: " + str(round(duration, 2)) + "s."
else:
mins = int(duration / 60)
secs = round(duration % 60, 2)
if mins < 60:
return "used: " + str(mins) + "m " + str(secs) + "s."
else:
hours = int(duration / 3600)
mins = mins % 60
return "used: " + str(hours) + "h " + str(mins) + "m " + str(secs) + "s."
Set a variable as start = time() before execute the function/loops, and printTime(start) right after the block.
and you got the answer.
How can I solve the error 'TS2532: Object is possibly 'undefined'?
For others facing a similar problem to mine, where you know a particular object property cannot be null, you can use the non-null assertion operator (!) after the item in question.
This was my code:
const naciStatus = dataToSend.naci?.statusNACI;
if (typeof naciStatus != "undefined") {
switch (naciStatus) {
case "AP":
dataToSend.naci.certificateStatus = "FALSE";
break;
case "AS":
case "WR":
dataToSend.naci.certificateStatus = "TRUE";
break;
default:
dataToSend.naci.certificateStatus = "";
}
}
And because dataToSend.naci cannot be undefined in the switch statement, the code can be updated to include exclamation marks as follows:
const naciStatus = dataToSend.naci?.statusNACI;
if (typeof naciStatus != "undefined") {
switch (naciStatus) {
case "AP":
dataToSend.naci!.certificateStatus = "FALSE";
break;
case "AS":
case "WR":
dataToSend.naci!.certificateStatus = "TRUE";
break;
default:
dataToSend.naci!.certificateStatus = "";
}
}
How to embed YouTube videos in PHP?
The <object> and <embed> tags are deprecated as per HTML Youtube Videos, it is preferable to use the <iframe> tag to do so.
<iframe width="420" height="315"
src="http://www.youtube.com/embed/XGSy3_Czz8k?autoplay=1">
</iframe>
In order for your users not spend their entire lifetime trying to find the video id in links to put it in your form field, let them post the link of the video they find on youtube and you can use the following regex to obtain the video id:
preg_match("/^(?:http(?:s)?:\/\/)?
(?:www\.)?(?:m\.)?(?:youtu\.be\/|youtube\.com\/(?:(?:watch)?\?(?:.*&)?v(?:i)?=|
(?:embed|v|vi|user)\/))([^\?&\"'>]+)/", $url, $matches);
To get the video id you can fetch it $matches[1], these will match:
Part of this answer is referred by @shawn's answer in this question.
How do I check in JavaScript if a value exists at a certain array index?
OK, let's first see what would happens if an array value not exist in JavaScript, so if we have an array like below:
const arr = [1, 2, 3, 4, 5];
and now we check if 6 is there at index 5 or not:
arr[5];
and we get
undefined...
So that's basically give us the answer, the best way to check if undefined, so something like this:
if("undefined" === typeof arrayName[index]) {
//array value is not there...
}
It's better NOT doing this in this case:
if(!arrayName[index]) {
//Don't check like this..
}
Because imagine we have this array:
const arr = [0, 1, 2];
and we do:
if(!arr[0]) {
//This get passed, because in JavaScript 0 is falsy
}
So as you see, even 0 is there, it doesn't get recognised, there are few other things which can do the same and make you application buggy, so be careful, I list them all down:
- undefined: if the value is not defined and it's
undefined
- null: if it's null, for example if a DOM element not exists...
- empty string:
''
- 0: number zero
- NaN: not a number
- false
Wheel file installation
You normally use a tool like pip to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.
For this to work, you do need to install the wheel package:
pip install wheel
You can then tell pip to install the project (and it'll download the wheel if available), or the wheel file directly:
pip install project_name # discover, download and install
pip install wheel_file.whl # directly install the wheel
The wheel module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:
python -m wheel install wheel_file.whl
Also see the wheel project documentation.
A reference to the dll could not be added
The following worked for me:
Short answer
Run the following via command line (cmd):
TlbImp.exe cvextern.dll //where cvextern.dll is your dll you want to fix.
And a valid dll will be created for you.
Longer answer
Open cmd
Find TlbImp.exe. Probably located in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin. If you can't find it go to your root folder (C:\ or D:) and run:
dir tlbimp.exe /s //this will locate the file.
Run tlbimp.exe and put your dll behind it. Example: If your dll is cvextern.dll. You can run:
TlbImp.exe cvextern.dll
- A new dll has been created in the same folder of tlbimp.exe. You can use that as reference in your project.
How To Convert A Number To an ASCII Character?
C# represents a character in UTF-16 coding rather than ASCII. Therefore converting a integer to character do not make any difference for A-Z and a-z. But I was working with ASCII Codes besides alphabets and number which did not work for me as system uses UTF-16 code. Therefore I browsed UTF-16 code for all UTF-16 character. Here is the module :
void utfchars()
{
int i, a, b, x;
ConsoleKeyInfo z;
do
{
a = 0; b = 0; Console.Clear();
for (i = 1; i <= 10000; i++)
{
if (b == 20)
{
b = 0;
a = a + 1;
}
Console.SetCursorPosition((a * 15) + 1, b + 1);
Console.Write("{0} == {1}", i, (char)i);
b = b+1;
if (i % 100 == 0)
{
Console.Write("\n\t\t\tPress any key to continue {0}", b);
a = 0; b = 0;
Console.ReadKey(true); Console.Clear();
}
}
Console.Write("\n\n\n\n\n\n\n\t\t\tPress any key to Repeat and E to exit");
z = Console.ReadKey();
if (z.KeyChar == 'e' || z.KeyChar == 'E') Environment.Exit(0);
} while (1 == 1);
}
The SELECT permission was denied on the object 'Users', database 'XXX', schema 'dbo'
Using SSMS, I made sure the user had connect permissions on both the database and ReportServer.
On the specific database being queried, under properties, I mapped their credentials and enabled datareader and public permissions. Also, as others have stated-I made sure there were no denyread/denywrite boxes selected.
I did not want to enable db ownership when for their reports since they only needed to have select permissions.

while((entrada = br.readLine())!=null){
st = new StringTokenizer(entrada," ");
while(st.hasMoreTokens()){
x = Long.parseLong(st.nextToken());
y = Long.parseLong(st.nextToken());
}
System.out.println(x>y ?(x-y)+"":(y-x)+"");

This solution is a bit more efficient than the one above because it takes up the 2.128 and this takes 1.308 seconds to solve the problem.
Function inside a function.?
It is possible to define a function from inside another function.
the inner function does not exist until the outer function gets executed.
echo function_exists("y") ? 'y is defined\n' : 'y is not defined \n';
$x=x(2);
echo function_exists("y") ? 'y is defined\n' : 'y is not defined \n';
Output
y is not defined
y is defined
Simple thing you can not call function y before executed x
Trusting all certificates using HttpClient over HTTPS

How do I set up Visual Studio Code to compile C++ code?
To Build/run C++ projects in VS code , you manually need to configure tasks.json file which is in .vscode folder in workspace folder .
To open tasks.json , press ctrl + shift + P , and type Configure tasks , and press enter, it will take you to tasks.json
Here i am providing my tasks.json file with some comments to make the file more understandable , It can be used as a reference for configuring tasks.json , i hope it will be useful

How do I use disk caching in Picasso?
For the most updated version 2.71828
These are your answer.
Q1: Does it not have local disk cache?
A1: There is default caching within Picasso and the request flow just like this
App -> Memory -> Disk -> Server
Wherever they met their image first, they'll use that image and then stop the request flow.
What about response flow? Don't worry, here it is.
Server -> Disk -> Memory -> App
By default, they will store into a local disk first for the extended keeping cache. Then the memory, for the instance usage of the cache.
You can use the built-in indicator in Picasso to see where images form by enabling this.
Picasso.get().setIndicatorEnabled(true);
It will show up a flag on the top left corner of your pictures.
- Red flag means the images come from the server. (No caching at first load)
- Blue flag means the photos come from the local disk. (Caching)
- Green flag means the images come from the memory. (Instance Caching)
Q2: How do I enable disk caching as I will be using the same image multiple times?
A2: You don't have to enable it. It's the default.
What you'll need to do is DISABLE it when you want your images always fresh. There is 2-way of disabled caching.
- Set
.memoryPolicy() to NO_CACHE and/or NO_STORE and the flow will look like this.
NO_CACHE will skip looking up images from memory.
App -> Disk -> Server
NO_STORE will skip store images in memory when the first load images.
Server -> Disk -> App
- Set
.networkPolicy() to NO_CACHE and/or NO_STORE and the flow will look like this.
NO_CACHE will skip looking up images from disk.
App -> Memory -> Server
NO_STORE will skip store images in the disk when the first load images.
Server -> Memory -> App
You can DISABLE neither for fully no caching images. Here is an example.
Picasso.get().load(imageUrl)
.memoryPolicy(MemoryPolicy.NO_CACHE,MemoryPolicy.NO_STORE)
.networkPolicy(NetworkPolicy.NO_CACHE, NetworkPolicy.NO_STORE)
.fit().into(banner);
The flow of fully no caching and no storing will look like this.
App -> Server //Request
Server -> App //Response
So, you may need this to minify your app storage usage also.
Q3: Do I need to add some disk permission to android manifest file?
A3: No, but don't forget to add the INTERNET permission for your HTTP request.

Apache giving 403 forbidden errors
I just fixed this issue after struggling for a few days. Here's what worked for me:
First, check your Apache error_log file and look at the most recent error message.
If it says something like:
access to /mySite denied (filesystem path
'/Users/myusername/Sites/mySite') because search permissions
are missing on a component of the path
then there is a problem with your file permissions. You can fix them by running these commands from the terminal:
$ cd /Users/myusername/Sites/mySite
$ find . -type f -exec chmod 644 {} \;
$ find . -type d -exec chmod 755 {} \;
Then, refresh the URL where your website should be (such as http://localhost/mySite).
If you're still getting a 403 error, and if your Apache error_log still says the same thing, then progressively move up your directory tree, adjusting the directory permissions as you go. You can do this from the terminal by:
$ cd ..
$ chmod 755 mySite
If necessary, continue with:
$ cd ..
$ chmod Sites
and, if necessary,
$ cd ..
$ chmod myusername
DO NOT go up farther than that. You could royally mess up your system.
If you still get the error that says search permissions are missing on a component of the path, I don't know what you should do. However, I encountered a different error (the one below) which I fixed as follows:
If your error_log says something like:
client denied by server configuration:
/Users/myusername/Sites/mySite
then your problem is not with your file permissions, but instead with your Apache configuration.
Notice that in your httpd.conf file, you will see a default configuration like this (Apache 2.4+):
<Directory />
AllowOverride none
Require all denied
</Directory>
or like this (Apache 2.2):
<Directory />
Order deny,allow
Deny from all
</Directory>
DO NOT change this! We will not override these permissions globally, but instead in your httpd-vhosts.conf file.
First, however, make sure that your vhost Include line in httpd.conf is uncommented. It should look like this. (Your exact path may be different.)
# Virtual hosts
Include etc/extra/httpd-vhosts.conf
Now, open the httpd-vhosts.conf file that you just Included. Add an entry for your webpage if you don't already have one. It should look something like this. The DocumentRoot and Directory paths should be identical, and should point to wherever your index.html or index.php file is located. For me, that's within the public subdirectory.
For Apache 2.2:
<VirtualHost *:80>
# ServerAdmin [email protected]
DocumentRoot "/Users/myusername/Sites/mySite/public"
ServerName mysite
# ErrorLog "logs/dummy-host2.example.com-error_log"
# CustomLog "logs/dummy-host2.example.com-access_log" common
<Directory "/Users/myusername/Sites/mySite/public">
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Order allow,deny
Allow from all
Require all granted
</Directory>
</VirtualHost>
The lines saying
AllowOverride All
Require all granted
are critical for Apache 2.4+. Without these, you will not be overriding the default Apache settings specified in httpd.conf. Note that if you are using Apache 2.2, these lines should instead say
Order allow,deny
Allow from all
This change has been a major source of confusion for googlers of this problem, such as I, because copy-pasting these Apache 2.2 lines will not work in Apache 2.4+, and the Apache 2.2 lines are still commonly found on older help threads.
Once you have saved your changes, restart Apache. The command for this will depend on your OS and installation, so google that separately if you need help with it.
I hope this helps someone else!
PS: If you are having trouble finding these .conf files, try running the find command, such as:
$ find / -name httpd.conf

What is the proper way to re-throw an exception in C#?
My preferences is to use
try
{
}
catch (Exception ex)
{
...
throw new Exception ("Put more context here", ex)
}
This preserves the original error, but allows you to put more context, such as an object ID, a connection string, stuff like that. Often my exception reporting tool will have 5 chained exceptions to report, each reporting more detail.
How to parse a JSON Input stream

How to check if a text field is empty or not in swift
if let ... where ... {
Swift 3:
if let _text = theTextField.text, _text.isEmpty {
// _text is not empty here
}
Swift 2:
if let theText = theTextField.text where !theTextField.text!.isEmpty {
// theText is not empty here
}
guard ... where ... else {
You can also use the keyword guard :
Swift 3:
guard let theText = theTextField.text where theText.isEmpty else {
// theText is empty
return // or throw
}
// you can use theText outside the guard scope !
print("user wrote \(theText)")
Swift 2:
guard let theText = theTextField.text where !theTextField.text!.isEmpty else {
// the text is empty
return
}
// you can use theText outside the guard scope !
print("user wrote \(theText)")
This is particularly great for validation chains, in forms for instance. You can write a guard let for each validation and return or throw an exception if there's a critical error.
Excel VBA Open a Folder
I use this to open a workbook and then copy that workbook's data to the template.

Understanding the ngRepeat 'track by' expression
You can track by $index if your data source has duplicate identifiers
e.g.: $scope.dataSource: [{id:1,name:'one'}, {id:1,name:'one too'}, {id:2,name:'two'}]
You can't iterate this collection while using 'id' as identifier (duplicate id:1).
WON'T WORK:
<element ng-repeat="item.id as item.name for item in dataSource">
// something with item ...
</element>
but you can, if using track by $index:
<element ng-repeat="item in dataSource track by $index">
// something with item ...
</element>
How to destroy a DOM element with jQuery?
If you want to completely destroy the target, you have a couple of options. First you can remove the object from the DOM as described above...
console.log($target); // jQuery object
$target.remove(); // remove target from the DOM
console.log($target); // $target still exists
Option 1 - Then replace target with an empty jQuery object (jQuery 1.4+)
$target = $();
console.log($target); // empty jQuery object
Option 2 - Or delete the property entirely (will cause an error if you reference it elsewhere)
delete $target;
console.log($target); // error: $target is not defined
More reading: info about empty jQuery object, and info about delete
Best way to change the background color for an NSView
Just small reusable class (Swift 4.1)

var backgroundColor: NSColor?
convenience init() {
self.init(frame: NSRect())
}
override func draw(_ dirtyRect: NSRect) {
if let backgroundColor = backgroundColor {
backgroundColor.setFill()
dirtyRect.fill()
} else {
super.draw(dirtyRect)
}
}
}
// Usage
let view = View()
view.backgroundColor = .white
CGContextDrawImage draws image upside down when passed UIImage.CGImage
During the course of my project I jumped from Kendall's answer to Cliff's answer to solve this problem for images that are loaded from the phone itself.
In the end I ended up using CGImageCreateWithPNGDataProvider instead:
NSString* imageFileName = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"clockdial.png"];
return CGImageCreateWithPNGDataProvider(CGDataProviderCreateWithFilename([imageFileName UTF8String]), NULL, YES, kCGRenderingIntentDefault);
This doesn't suffer from the orientation issues that you would get from getting the CGImage from a UIImage and it can be used as the contents of a CALayer without a hitch.
How to display image with JavaScript?
You could make use of the Javascript DOM API. In particular, look at the createElement() method.
You could create a re-usable function that will create an image like so...
function show_image(src, width, height, alt) {
var img = document.createElement("img");
img.src = src;
img.width = width;
img.height = height;
img.alt = alt;
// This next line will just add it to the <body> tag
document.body.appendChild(img);
}
Then you could use it like this...
<button onclick=
"show_image('http://google.com/images/logo.gif',
276,
110,
'Google Logo');">Add Google Logo</button>

Is it possible to get a list of files under a directory of a website? How?
Any crawler or spider will read your index.htm or equivalent, that is exposed to the web, they will read the source code for that page, and find everything that is associated to that webpage and contains subdirectories. If they find a "contact us" button, there may be is included the path to the webpage or php that deal with the contact-us action, so they now have one more subdirectory/folder name to crawl and dig more. But even so, if that folder has a index.htm or equivalent file, it will not list all the files in such folder.
If by mistake, the programmer never included an index.htm file in such folder, then all the files will be listed on your computer screen, and also for the crawler/spider to keep digging. But, if you created a folder www.yoursite.com/nombresinistro75crazyragazzo19/ and put several files in there, and never published any button or never exposed that folder address anywhere in the net, keeping only in your head, chances are that nobody ever will find that path, with crawler or spider, for more sophisticated it can be.
Except, of course, if they can enter your FTP or access your site control panel.
How to split a delimited string in Ruby and convert it to an array?
>> "1,2,3,4".split(",")
=> ["1", "2", "3", "4"]
Or for integers:
>> "1,2,3,4".split(",").map { |s| s.to_i }
=> [1, 2, 3, 4]
Or for later versions of ruby (>= 1.9 - as pointed out by Alex):
>> "1,2,3,4".split(",").map(&:to_i)
=> [1, 2, 3, 4]
C#: Waiting for all threads to complete
I still think using Join is simpler. Record the expected completion time (as Now+timeout), then, in a loop, do
if(!thread.Join(End-now))
throw new NotFinishedInTime();
What does CultureInfo.InvariantCulture mean?
When numbers, dates and times are formatted into strings or parsed from strings a culture is used to determine how it is done. E.g. in the dominant en-US culture you have these string representations:
- 1,000,000.00 - one million with a two digit fraction
- 1/29/2013 - date of this posting
In my culture (da-DK) the values have this string representation:
- 1.000.000,00 - one million with a two digit fraction
- 29-01-2013 - date of this posting
In the Windows operating system the user may even customize how numbers and date/times are formatted and may also choose another culture than the culture of his operating system. The formatting used is the choice of the user which is how it should be.
So when you format a value to be displayed to the user using for instance ToString or String.Format or parsed from a string using DateTime.Parse or Decimal.Parse the default is to use the CultureInfo.CurrentCulture. This allows the user to control the formatting.
However, a lot of string formatting and parsing is actually not strings exchanged between the application and the user but between the application and some data format (e.g. an XML or CSV file). In that case you don't want to use CultureInfo.CurrentCulture because if formatting and parsing is done with different cultures it can break. In that case you want to use CultureInfo.InvariantCulture (which is based on the en-US culture). This ensures that the values can roundtrip without problems.
The reason that ReSharper gives you the warning is that some application writers are unaware of this distinction which may lead to unintended results but they never discover this because their CultureInfo.CurrentCulture is en-US which has the same behavior as CultureInfo.InvariantCulture. However, as soon as the application is used in another culture where there is a chance of using one culture for formatting and another for parsing the application may break.
So to sum it up:
- Use
CultureInfo.CurrentCulture (the default) if you are formatting or parsing a user string.
- Use
CultureInfo.InvariantCulture if you are formatting or parsing a string that should be parseable by a piece of software.
- Rarely use a specific national culture because the user is unable to control how formatting and parsing is done.
How to create a windows service from java app
If you use Gradle Build Tool you can try my windows-service-plugin, which facilitates using of Apache Commons Daemon Procrun.
To create a java windows service application with the plugin you need to go through several simple steps.
Create a main service class with the appropriate method.
public class MyService {
public static void main(String[] args) {
String command = "start";
if (args.length > 0) {
command = args[0];
}
if ("start".equals(command)) {
// process service start function
} else {
// process service stop function
}
}
}
Include the plugin into your build.gradle file.
buildscript {
repositories {
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
classpath "gradle.plugin.com.github.alexeylisyutenko:windows-service-plugin:1.1.0"
}
}
apply plugin: "com.github.alexeylisyutenko.windows-service-plugin"
The same script snippet for new, incubating, plugin mechanism introduced in Gradle 2.1:
plugins {
id "com.github.alexeylisyutenko.windows-service-plugin" version "1.1.0"
}
Configure the plugin.
windowsService {
architecture = 'amd64'
displayName = 'TestService'
description = 'Service generated with using gradle plugin'
startClass = 'MyService'
startMethod = 'main'
startParams = 'start'
stopClass = 'MyService'
stopMethod = 'main'
stopParams = 'stop'
startup = 'auto'
}
Run createWindowsService gradle task to create a windows service distribution.
That's all you need to do to create a simple windows service. The plugin will automatically download Apache Commons Daemon Procrun binaries, extract this binaries to the service distribution directory and create batch files for installation/uninstallation of the service.
In ${project.buildDir}/windows-service directory you will find service executables, batch scripts for installation/uninstallation of the service and all runtime libraries.
To install the service run <project-name>-install.bat and if you want to uninstall the service run <project-name>-uninstall.bat.
To start and stop the service use <project-name>w.exe executable.
Note that the method handling service start should create and start a separate thread to carry out the processing, and then return. The main method is called from different threads when you start and stop the service.
For more information, please read about the plugin and Apache Commons Daemon Procrun.
What does ellipsize mean in android?
You can find documentation here.
Based on your requirement you can try according option.
to ellipsize, a neologism, means to shorten text using an ellipsis, i.e. three dots ... or more commonly ligature …, to stand in for the omitted bits.
Say original value pf text view is aaabbbccc and its fitting inside the view
start's output will be : ...bccc
end's output will be : aaab...
middle's output will be : aa...cc
marquee's output will be : aaabbbccc auto sliding from right to left
How can I install a previous version of Python 3 in macOS using homebrew?
In case anyone face pip issue like below
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
The root cause is openssl 1.1 doesn’t support python 3.6 anymore. So you need to install old version openssl 1.0
here is the solution:
brew uninstall --ignore-dependencies openssl
brew install https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb
Two onClick actions one button

<input type="button" value="Dont show this again! " onClick="clickEvent();" />
Valid content-type for XML, HTML and XHTML documents
HTML: text/html, full-stop.
XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.
XML: text/xml, application/xml (RFC 2376).
There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.
(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)
Handling urllib2's timeout? - Python
There are very few cases where you want to use except:. Doing this captures any exception, which can be hard to debug, and it captures exceptions including SystemExit and KeyboardInterupt, which can make your program annoying to use..
At the very simplest, you would catch urllib2.URLError:
try:
urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
raise MyException("There was an error: %r" % e)
The following should capture the specific error raised when the connection times out:
import urllib2
import socket
class MyException(Exception):
pass
try:
urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
# For Python 2.6
if isinstance(e.reason, socket.timeout):
raise MyException("There was an error: %r" % e)
else:
# reraise the original error
raise
except socket.timeout, e:
# For Python 2.7
raise MyException("There was an error: %r" % e)
How to count duplicate value in an array in javascript
You can solve it without using any for/while loops ou forEach.
function myCounter(inputWords) {
return inputWords.reduce( (countWords, word) => {
countWords[word] = ++countWords[word] || 1;
return countWords;
}, {});
}
Hope it helps you!
How do I get the web page contents from a WebView?
You also need to annotate the method with @JavascriptInterface if your targetSdkVersion is >= 17 - because there is new security requirements in SDK 17, i.e. all javascript methods must be annotated with @JavascriptInterface. Otherwise you will see error like: Uncaught TypeError: Object [object Object] has no method 'processHTML' at null:1
How to trigger a click on a link using jQuery
If you are trying to trigger an event on the anchor, then the code you have will work I recreated your example in jsfiddle with an added eventHandler so you can see that it works:
$(document).on("click", "a", function(){
$(this).text("It works!");
});
$(document).ready(function(){
$("a").trigger("click");
});
Are you trying to cause the user to navigate to a certain point on the webpage by clicking the anchor, or are you trying to trigger events bound to it? Maybe you haven't actually bound the click event successfully to the event?
Also this:
$('#titleee').find('a').trigger('click');
is the equivalent of this:
$('#titleee a').trigger('click');
No need to call find. :)
What is the difference between canonical name, simple name and class name in Java Class?
getName() – returns the name of the entity (class, interface, array class, primitive type, or void) represented by this Class object, as a String.
getCanonicalName() – returns the canonical name of the underlying class as defined by the Java Language Specification.
getSimpleName() – returns the simple name of the underlying class, that is the name it has been given in the source code.
package com.practice;
public class ClassName {
public static void main(String[] args) {
ClassName c = new ClassName();
Class cls = c.getClass();
// returns the canonical name of the underlying class if it exists
System.out.println("Class = " + cls.getCanonicalName()); //Class = com.practice.ClassName
System.out.println("Class = " + cls.getName()); //Class = com.practice.ClassName
System.out.println("Class = " + cls.getSimpleName()); //Class = ClassName
System.out.println("Class = " + Map.Entry.class.getName()); // -> Class = java.util.Map$Entry
System.out.println("Class = " + Map.Entry.class.getCanonicalName()); // -> Class = java.util.Map.Entry
System.out.println("Class = " + Map.Entry.class.getSimpleName()); // -> Class = Entry
}
}
One difference is that if you use an anonymous class you can get a null value when trying to get the name of the class using the getCanonicalName()
Another fact is that getName() method behaves differently than the getCanonicalName() method for inner classes. getName() uses a dollar as the separator between the enclosing class canonical name and the inner class simple name.
To know more about retrieving a class name in Java.
Rollback to an old Git commit in a public repo
Try this:
git checkout [revision] .
where [revision] is the commit hash (for example: 12345678901234567890123456789012345678ab).
Don't forget the . at the end, very important. This will apply changes to the whole tree. You should execute this command in the git project root. If you are in any sub directory, then this command only changes the files in the current directory. Then commit and you should be good.
You can undo this by
git reset --hard
that will delete all modifications from the working directory and staging area.

Check if a file exists in jenkins pipeline
You need to use brackets when using the fileExists step in an if condition or assign the returned value to a variable
Using variable:
def exists = fileExists 'file'
if (exists) {
echo 'Yes'
} else {
echo 'No'
}
Using brackets:
if (fileExists('file')) {
echo 'Yes'
} else {
echo 'No'
}
error, string or binary data would be truncated when trying to insert
In one of the INSERT statements you are attempting to insert a too long string into a string (varchar or nvarchar) column.
If it's not obvious which INSERT is the offender by a mere look at the script, you could count the <1 row affected> lines that occur before the error message. The obtained number plus one gives you the statement number. In your case it seems to be the second INSERT that produces the error.
HtmlSpecialChars equivalent in Javascript?
function htmlEscape(str){
return str.replace(/[&<>'"]/g,x=>'&#'+x.charCodeAt(0)+';')
}
This solution uses the numerical code of the characters, for example < is replaced by <.
Although its performance is slightly worse than the solution using a map, it has the advantages:
- Not dependent on a library or DOM
- Pretty easy to remember (you don't need to memorize the 5 HTML escape characters)
- Little code
- Reasonably fast (it's still faster than 5 chained replace)
Why should C++ programmers minimize use of 'new'?
The reason why is complicated.
First, C++ is not garbage collected. Therefore, for every new, there must be a corresponding delete. If you fail to put this delete in, then you have a memory leak. Now, for a simple case like this:
std::string *someString = new std::string(...);
//Do stuff
delete someString;
This is simple. But what happens if "Do stuff" throws an exception? Oops: memory leak. What happens if "Do stuff" issues return early? Oops: memory leak.
And this is for the simplest case. If you happen to return that string to someone, now they have to delete it. And if they pass it as an argument, does the person receiving it need to delete it? When should they delete it?
Or, you can just do this:
std::string someString(...);
//Do stuff
No delete. The object was created on the "stack", and it will be destroyed once it goes out of scope. You can even return the object, thus transfering its contents to the calling function. You can pass the object to functions (typically as a reference or const-reference: void SomeFunc(std::string &iCanModifyThis, const std::string &iCantModifyThis). And so forth.
All without new and delete. There's no question of who owns the memory or who's responsible for deleting it. If you do:
std::string someString(...);
std::string otherString;
otherString = someString;
It is understood that otherString has a copy of the data of someString. It isn't a pointer; it is a separate object. They may happen to have the same contents, but you can change one without affecting the other:
someString += "More text.";
if(otherString == someString) { /*Will never get here */ }
See the idea?
How to loop over files in directory and change path and add suffix to filename
A couple of notes first: when you use Data/data1.txt as an argument, should it really be /Data/data1.txt (with a leading slash)? Also, should the outer loop scan only for .txt files, or all files in /Data? Here's an answer, assuming /Data/data1.txt and .txt files only:
#!/bin/bash
for filename in /Data/*.txt; do
for ((i=0; i<=3; i++)); do
./MyProgram.exe "$filename" "Logs/$(basename "$filename" .txt)_Log$i.txt"
done
done
Notes:
/Data/*.txt expands to the paths of the text files in /Data (including the /Data/ part)$( ... ) runs a shell command and inserts its output at that point in the command linebasename somepath .txt outputs the base part of somepath, with .txt removed from the end (e.g. /Data/file.txt -> file)
If you needed to run MyProgram with Data/file.txt instead of /Data/file.txt, use "${filename#/}" to remove the leading slash. On the other hand, if it's really Data not /Data you want to scan, just use for filename in Data/*.txt.
Spin or rotate an image on hover
You can use CSS3 transitions with rotate() to spin the image on hover.
Rotating image :
_x000D_
_x000D_
img {_x000D_
border-radius: 50%;_x000D_
-webkit-transition: -webkit-transform .8s ease-in-out;_x000D_
transition: transform .8s ease-in-out;_x000D_
}_x000D_
img:hover {_x000D_
-webkit-transform: rotate(360deg);_x000D_
transform: rotate(360deg);_x000D_
}
_x000D_
<img src="https://i.stack.imgur.com/BLkKe.jpg" width="100" height="100"/>
_x000D_
_x000D_
_x000D_
Here is a fiddle DEMO

How can I pause setInterval() functions?
I know this thread is old, but this could be another solution:
var do_this = null;
function y(){
// what you wanna do
}
do_this = setInterval(y, 1000);
function y_start(){
do_this = setInterval(y, 1000);
};
function y_stop(){
do_this = clearInterval(do_this);
};
Android: how to make an activity return results to the activity which calls it?
If you want to finish and just add a resultCode (without data), you can call setResult(int resultCode) before finish().
For example:
...
if (everything_OK) {
setResult(Activity.RESULT_OK); // OK! (use whatever code you want)
finish();
}
else {
setResult(Activity.RESULT_CANCELED); // some error ...
finish();
}
...
Then in your calling activity, check the resultCode, to see if we're OK.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == someCustomRequestCode) {
if (resultCode == Activity.RESULT_OK) {
// OK!
}
else if (resultCode = Activity.RESULT_CANCELED) {
// something went wrong :-(
}
}
}
Don't forget to call the activity with startActivityForResult(intent, someCustomRequestCode).
Read tab-separated file line into array
If you really want to split every word (bash meaning) into a different array index completely changing the array in every while loop iteration, @ruakh's answer is the correct approach. But you can use the read property to split every read word into different variables column1, column2, column3 like in this code snippet
while IFS=$'\t' read -r column1 column2 column3 ; do
printf "%b\n" "column1<${column1}>"
printf "%b\n" "column2<${column2}>"
printf "%b\n" "column3<${column3}>"
done < "myfile"
to reach a similar result avoiding array index access and improving your code readability by using meaningful variable names (of course using columnN is not a good idea to do so).
How do I get a range's address including the worksheet name, but not the workbook name, in Excel VBA?
I found the following worked for me in a user defined function I created. I concatenated the cell range reference and worksheet name as a string and then used in an Evaluate statement (I was using Evaluate on Sumproduct).
For example:
Function SumRange(RangeName as range)
Dim strCellRef, strSheetName, strRngName As String
strCellRef = RangeName.Address
strSheetName = RangeName.Worksheet.Name & "!"
strRngName = strSheetName & strCellRef
Then refer to strRngName in the rest of your code.
Custom CSS Scrollbar for Firefox
May I offer an alternative?
No scripting whatsoever, only standardized css styles and a little bit of creativity. Short answer - masking parts of the existing browser scrollbar, which means you retain all of it's functionality.
.scroll_content {
position: relative;
width: 400px;
height: 414px;
top: -17px;
padding: 20px 10px 20px 10px;
overflow-y: auto;
}

Can I set variables to undefined or pass undefined as an argument?
Just for fun, here's a fairly safe way to assign "unassigned" to a variable. For this to have a collision would require someone to have added to the prototype for Object with exactly the same name as the randomly generated string. I'm sure the random string generator could be improved, but I just took one from this question: Generate random string/characters in JavaScript
This works by creating a new object and trying to access a property on it with a randomly generated name, which we are assuming wont exist and will hence have the value of undefined.
function GenerateRandomString() {
var text = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
for (var i = 0; i < 50; i++)
text += possible.charAt(Math.floor(Math.random() * possible.length));
return text;
}
var myVar = {}[GenerateRandomString()];
Why do we have to normalize the input for an artificial neural network?
It's explained well here.
If the input variables are combined linearly, as in an MLP [multilayer perceptron], then it is
rarely strictly necessary to standardize the inputs, at least in theory. The
reason is that any rescaling of an input vector can be effectively undone by
changing the corresponding weights and biases, leaving you with the exact
same outputs as you had before. However, there are a variety of practical
reasons why standardizing the inputs can make training faster and reduce the
chances of getting stuck in local optima. Also, weight decay and Bayesian
estimation can be done more conveniently with standardized inputs.
Crop image in android
This library: Android-Image-Cropper is very powerful to CropImages. It has 3,731 stars on github at this time.
You will crop your images with a few lines of code.
1 - Add the dependecies into buid.gradle (Module: app)
compile 'com.theartofdev.edmodo:android-image-cropper:2.7.+'
2 - Add the permissions into AndroidManifest.xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
3 - Add CropImageActivity into AndroidManifest.xml
<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
android:theme="@style/Base.Theme.AppCompat"/>
4 - Start the activity with one of the cases below, depending on your requirements.
// start picker to get image for cropping and then use the image in cropping activity
CropImage.activity()
.setGuidelines(CropImageView.Guidelines.ON)
.start(this);
// start cropping activity for pre-acquired image saved on the device
CropImage.activity(imageUri)
.start(this);
// for fragment (DO NOT use `getActivity()`)
CropImage.activity()
.start(getContext(), this);
5 - Get the result in onActivityResult
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
CropImage.ActivityResult result = CropImage.getActivityResult(data);
if (resultCode == RESULT_OK) {
Uri resultUri = result.getUri();
} else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
Exception error = result.getError();
}
}
}
You can do several customizations, as set the Aspect Ratio or the shape to RECTANGLE, OVAL and a lot more.
Adding one day to a date
Since you already have an answer to what's wrong with your code, I can bring another perspective on how you can play with datetimes generally, and solve your problem specifically.
Oftentimes you find yourself posing a problem in terms of solution. This is just one of the reasons you end up with an imperative code. It's great if it works though; there are just other, arguably more maintainable alternatives. One of them is a declarative code. The point is asking what you need, instead of how to get there.
In your particular case, this can look like the following. First, you need to find out what is it that you're looking for, that is, discover abstractions. In your case, it looks like you need a date. Not just any date, but the one having some standard representation. Say, ISO8601 date. There are at least two implementations: the first one is a date parsed from an ISO8601-formatted string (or a string in any other format actually), and the second is some future date which is a day later. Thus, the whole code could look like that:
(new Future(
new DateTimeParsedFromISO8601('2009-09-30 20:24:00'),
new OneDay()
))
->value();
For more examples with datetime juggling check out this one.
Change background color of R plot
Old question but I have a much better way of doing this. Rather than using rect() use polygon. This allows you to keep everything in plot without using points. Also you don't have to mess with par at all. If you want to keep things automated make the coordinates of polygon a function of your data.
plot.new()
polygon(c(-min(df[,1])^2,-min(df[,1])^2,max(df[,1])^2,max(df[,1])^2),c(-min(df[,2])^2,max(df[,2])^2,max(df[,2])^2,-min(df[,2])^2), col="grey")
par(new=T)
plot(df)
Indent multiple lines quickly in vi
How to indent highlighted code in vi immediately by a number of spaces:
Option 1: Indent a block of code in vi to three spaces with Visual Block mode:
Select the block of code you want to indent. Do this using Ctrl+V in normal mode and arrowing down to select text. While it is selected, enter : to give a command to the block of selected text.
The following will appear in the command line: :'<,'>
To set indent to three spaces, type le 3 and press enter. This is what appears: :'<,'>le 3
The selected text is immediately indented to three spaces.
Option 2: Indent a block of code in vi to three spaces with Visual Line mode:
- Open your file in vi.
- Put your cursor over some code
Be in normal mode and press the following keys:
Vjjjj:le 3
Interpretation of what you did:
V means start selecting text.
jjjj arrows down four lines, highlighting four lines.
: tells vi you will enter an instruction for the highlighted text.
le 3 means indent highlighted text three lines.
The selected code is immediately increased or decreased to three spaces indentation.
Option 3: use Visual Block mode and special insert mode to increase indent:
- Open your file in vi.
- Put your cursor over some code
Be in normal mode press the following keys:
Ctrl+V
jjjj
(press the spacebar five times)
Esc
Shift+i
All the highlighted text is indented an additional five spaces.
Unescape HTML entities in Javascript?
CMS' answer works fine, unless the HTML you want to unescape is very long, longer than 65536 chars. Because then in Chrome the inner HTML gets split into many child nodes, each one at most 65536 long, and you need to concatenate them. This function works also for very long strings:
function unencodeHtmlContent(escapedHtml) {
var elem = document.createElement('div');
elem.innerHTML = escapedHtml;
var result = '';
// Chrome splits innerHTML into many child nodes, each one at most 65536.
// Whereas FF creates just one single huge child node.
for (var i = 0; i < elem.childNodes.length; ++i) {
result = result + elem.childNodes[i].nodeValue;
}
return result;
}
See this answer about innerHTML max length for more info: https://stackoverflow.com/a/27545633/694469
Comparison between Corona, Phonegap, Titanium
I've tried corona. It was good until I discovered it doesn't support streaming mp3 audio.
So, I stopped right there. I think if I really want to be an iphone app developer I should learn obj c. All I wanted to make an app which has a list of radio stations and you click on them it start playing.
What are good ways to prevent SQL injection?
By using the SqlCommand and its child collection of parameters all the pain of checking for sql injection is taken away from you and will be handled by these classes.
Here is an example, taken from one of the articles above:
private static void UpdateDemographics(Int32 customerID,
string demoXml, string connectionString)
{
// Update the demographics for a store, which is stored
// in an xml column.
string commandText = "UPDATE Sales.Store SET Demographics = @demographics "
+ "WHERE CustomerID = @ID;";
using (SqlConnection connection = new SqlConnection(connectionString))
{
SqlCommand command = new SqlCommand(commandText, connection);
command.Parameters.Add("@ID", SqlDbType.Int);
command.Parameters["@ID"].Value = customerID;
// Use AddWithValue to assign Demographics.
// SQL Server will implicitly convert strings into XML.
command.Parameters.AddWithValue("@demographics", demoXml);
try
{
connection.Open();
Int32 rowsAffected = command.ExecuteNonQuery();
Console.WriteLine("RowsAffected: {0}", rowsAffected);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
}
Is there a way to get a collection of all the Models in your Rails app?
I'm just throwing this example here if anyone finds it useful. Solution is based on this answer https://stackoverflow.com/a/10712838/473040.
Let say you have a column public_uid that is used as a primary ID to outside world (you can findjreasons why you would want to do that here)
Now let say you've introduced this field on bunch of existing Models and now you want to regenerate all the records that are not yet set. You can do that like this
# lib/tasks/data_integirity.rake
namespace :di do
namespace :public_uids do
desc "Data Integrity: genereate public_uid for any model record that doesn't have value of public_uid"
task generate: :environment do
Rails.application.eager_load!
ActiveRecord::Base
.descendants
.select {|f| f.attribute_names.include?("public_uid") }
.each do |m|
m.where(public_uid: nil).each { |mi| puts "Generating public_uid for #{m}#id #{mi.id}"; mi.generate_public_uid; mi.save }
end
end
end
end
you can now run rake di:public_uids:generate
Can I get a patch-compatible output from git-diff?
If you want to use patch you need to remove the a/ b/ prefixes that git uses by default. You can do this with the --no-prefix option (you can also do this with patch's -p option):
git diff --no-prefix [<other git-diff arguments>]
Usually though, it is easier to use straight git diff and then use the output to feed to git apply.
Most of the time I try to avoid using textual patches. Usually one or more of temporary commits combined with rebase, git stash and bundles are easier to manage.
For your use case I think that stash is most appropriate.
# save uncommitted changes
git stash
# do a merge or some other operation
git merge some-branch
# re-apply changes, removing stash if successful
# (you may be asked to resolve conflicts).
git stash pop
Hidden property of a button in HTML
It also works without jQuery if you do the following changes:
Add type="button" to the edit button in order not to trigger submission of the form.
Change the name of your function from change() to anything else.
Don't use hidden="hidden", use CSS instead: style="display: none;".
The following code works for me:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="STYLESHEET" type="text/css" href="dba_style/buttons.css" />
<title>Untitled Document</title>
</head>
<script type="text/javascript">
function do_change(){
document.getElementById("save").style.display = "block";
document.getElementById("change").style.display = "block";
document.getElementById("cancel").style.display = "block";
}
</script>
<body>
<form name="form1" method="post" action="">
<div class="buttons">
<button type="button" class="regular" name="edit" id="edit" onclick="do_change(); return false;">
<img src="dba_images/textfield_key.png" alt=""/>
Edit
</button>
<button type="submit" class="positive" name="save" id="save" style="display:none;">
<img src="dba_images/apply2.png" alt=""/>
Save
</button>
<button class="regular" name="change" id="change" style="display:none;">
<img src="dba_images/textfield_key.png" alt=""/>
change
</button>
<button class="negative" name="cancel" id="cancel" style="display:none;">
<img src="dba_images/cross.png" alt=""/>
Cancel
</button>
</div>
</form>
</body>
</html>
How to get current instance name from T-SQL
To get the list of server and instance that you're connected to:

ListAGG in SQLSERVER
Starting in SQL Server 2017 the STRING_AGG function is available which simplifies the logic considerably:
select FieldA, string_agg(FieldB, '') as data
from yourtable
group by FieldA
See SQL Fiddle with Demo
In SQL Server you can use FOR XML PATH to get the result:
select distinct t1.FieldA,
STUFF((SELECT distinct '' + t2.FieldB
from yourtable t2
where t1.FieldA = t2.FieldA
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,0,'') data
from yourtable t1;
See SQL Fiddle with Demo
How can I get the assembly file version
When I want to access the application file version (what is set in Assembly Information -> File version), say to set a label's text to it on form load to display the version, I have just used
versionlabel.Text = "Version " + Application.ProductVersion;
This approach requires a reference to System.Windows.Forms.
ASP.NET MVC 5 - Identity. How to get current ApplicationUser
The code of Ellbar works! You need only add using.
1 - using Microsoft.AspNet.Identity;
And... the code of Ellbar:
2 - string currentUserId = User.Identity.GetUserId();
ApplicationUser currentUser = db.Users.FirstOrDefault(x => x.Id == currentUserId);
With this code (in currentUser), you work the general data of the connected user, if you want extra data... see this link
Link to all Visual Studio $ variables
Nikita's answer is nice for the macros that Visual Studio sets up in its environment, but this is far from comprehensive. (Environment variables become MSBuild macros, but not vis-a-versa.)
Slight tweak to ojdo's answer: Go to the "Pre-build event command line" in "Build Events" of the IDE for any project (where you find this in the IDE may depend on the language, i.e. C#, c++, etc. See other answers for location.) Post the code below into the "Pre-build event command line", then build that project. After the build starts, you will have a "macros.txt" file in your TEMP directory with a nice list of all the macros and their values. I based the list entirely on the list contained within ojdo's answer. I have no idea if it is comprehensive, but it's a good start!

Kill a Process by Looking up the Port being used by it from a .BAT
Just for completion:
I wanted to kill all processes connected to a specific port but not the process listening
the command (in cmd shell) for the port 9001 is:
FOR /F "tokens=5 delims= " %P IN ('netstat -ano ^| findstr -rc:":9001[ ]*ESTA"') DO TaskKill /F /PID %P
findstr:
- r is for expressions and c for exact chain to match.
- [ ]* is for matching spaces
netstat:
- a -> all
- n -> don't resolve (faster)
- o -> pid
It works because netstat prints out the source port then destination port and then ESTABLISHED
How to send and receive JSON data from a restful webservice using Jersey API
For me, parameter (JSONObject inputJsonObj) was not working. I am using jersey 2.* Hence I feel this is the
java(Jax-rs) and Angular way
I hope it's helpful to someone using JAVA Rest and AngularJS like me.
@POST
@Consumes(MediaType.TEXT_PLAIN)
@Produces(MediaType.APPLICATION_JSON)
public Map<String, String> methodName(String data) throws Exception {
JSONObject recoData = new JSONObject(data);
//Do whatever with json object
}
Client side I used AngularJS
factory.update = function () {
data = {user:'Shreedhar Bhat',address:[{houseNo:105},{city:'Bengaluru'}]};
data= JSON.stringify(data);//Convert object to string
var d = $q.defer();
$http({
method: 'POST',
url: 'REST/webApp/update',
headers: {'Content-Type': 'text/plain'},
data:data
})
.success(function (response) {
d.resolve(response);
})
.error(function (response) {
d.reject(response);
});
return d.promise;
};
How to grep for two words existing on the same line?
Here is the syntax using git grep combining multiple patterns using Boolean expressions:
git grep -e pattern1 --and -e pattern2 --and -e pattern3
The above command will print lines matching all the patterns at once.
If the files aren't under version control, add --no-index param.
Search files in the current directory that is not managed by Git.
Check man git-grep for help.

for each inside a for each - Java
If I understand correctly, what you want to do, in pseudo-code is the following:
for (Tweet tweet : tweets) {
if (!db.containsTweet(tweet.getId())) {
db.insertTweet(tweet.getText(), tweet.getId());
}
}
I assume your db class actually uses an sqlite database as a backend? What you could do is implement containsTweet directly and just query the database each time, but that seems less than perfect. The easiest solution if we go by your base code is to just keep a Set around that indexes the tweets. Since I can't be sure what the equals() method of Tweet looks like, I'll just store the identifiers in there. Then you get:
Set<Integer> tweetIds = new HashSet<Integer>(); // or long, whatever
for (Tweet tweet : tweets) {
if (!tweetIds.contains(tweet.getId())) {
db.insertTweet(tweet.getText(), tweet.getId());
tweetIds.add(tweet.getId());
}
}
It would probably be better to save a tiny bit of this work, by sorting the list of tweets to begin with and then just filtering out duplicate tweets. You could use:
// if tweets is a List
Collections.sort(tweets, new Comparator() {
public int compare (Object t1, Object t2) {
// might be the wrong way around
return ((Tweet)t1).getId() - ((Tweet)t2).getId();
}
}
Then process it
Integer oldId;
for (Tweet tweet : tweets) {
if (oldId == null || oldId != tweet.getId()) {
db.insertTweet(tweet.getText(), tweet.getId());
}
oldId = tweet.getId();
}
Yes, you could do this using a second for-loop, but you'll run into performance problems much more quickly than with this approach (although what we're doing here is trading time for memory performance, of course).
PHP how to get local IP of system
A reliable way to get the external IP address of the local machine would be to query the routing table, although we have no direct way to do it in PHP.
However we can get the system to do it for us by binding a UDP socket to a public address, and getting its address:
$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_connect($sock, "8.8.8.8", 53);
socket_getsockname($sock, $name); // $name passed by reference
// This is the local machine's external IP address
$localAddr = $name;
socket_connect will not cause any network traffic because it's an UDP socket.
How to split strings into text and number?
I would approach this by using re.match in the following way:
import re
match = re.match(r"([a-z]+)([0-9]+)", 'foofo21', re.I)
if match:
items = match.groups()
print(items)
>> ("foofo", "21")
Retain precision with double in Java
As others have noted, not all decimal values can be represented as binary since decimal is based on powers of 10 and binary is based on powers of two.
If precision matters, use BigDecimal, but if you just want friendly output:
System.out.printf("%.2f\n", total);
Will give you:
11.40
How to handle floats and decimal separators with html5 input type number
Whether to use comma or period for the decimal separator is entirely up to the browser. The browser makes it decision based on the locale of the operating system or browser, or some browsers take hints from the website. I made a browser comparison chart showing how different browsers support handle different localization methods. Safari being the only browser that handle commas and periods interchangeably.
Basically, you as a web author cannot really control this. Some work-arounds involves using two input fields with integers. This allows every user to input the data as yo expect. Its not particular sexy, but it will work in every case for all users.

These solutions totally make sense. Unfortunately, neither worked for me as expected. Instead of trying to hassle with it, I went with a work around:

order by table_name

Converting a Uniform Distribution to a Normal Distribution
There are plenty of methods:
- Do not use Box Muller. Especially if you draw many gaussian numbers. Box Muller yields a result which is clamped between -6 and 6 (assuming double precision. Things worsen with floats.). And it is really less efficient than other available methods.
- Ziggurat is fine, but needs a table lookup (and some platform-specific tweaking due to cache size issues)
- Ratio-of-uniforms is my favorite, only a few addition/multiplications and a log 1/50th of the time (eg. look there).
- Inverting the CDF is efficient (and overlooked, why ?), you have fast implementations of it available if you search google. It is mandatory for Quasi-Random numbers.
write a shell script to ssh to a remote machine and execute commands
You can follow this approach :
- Connect to remote machine using Expect Script. If your machine doesn't support expect you can download the same. Writing Expect script is very easy (google to get help on this)
- Put all the action which needs to be performed on remote server in a shell script.
- Invoke remote shell script from expect script once login is successful.
Docker - a way to give access to a host USB or serial device?
If you would like to dynamically access USB devices which can be plugged in while the docker container is already running, for example access a just attached usb webcam at /dev/video0, you can add a cgroup rule when starting the container. This option does not need a --privileged container and only allows access to specific types of hardware.
Step 1
Check the device major number of the type of device you would like to add. You can look it up in the linux kernel documentation. Or you can check it for your device. For example to check the device major number for a webcam connected to /dev/video0, you can do a ls -la /dev/video0. This results in something like:
crw-rw----+ 1 root video 81, 0 Jul 6 10:22 /dev/video0
Where the first number (81) is the device major number. Some common device major numbers:
- 81: usb webcams
- 188: usb to serial converters
Step 2
Add rules when you start the docker container:
- Add a
--device-cgroup-rule='c major_number:* rmw' rule for every type of device you want access to
- Add access to udev information so docker containers can get more info on your usb devices with
-v /run/udev:/run/udev:ro
- Map the /dev volume to your docker container with
-v /dev:/dev
Wrap up
So to add all usb webcams and serial2usb devices to your docker container, do:
docker run -it -v /dev:/dev --device-cgroup-rule='c 188:* rmw' --device-cgroup-rule='c 81:* rmw' ubuntu bash
Best way to deploy Visual Studio application that can run without installing
It is possible and is deceptively easy:
- "Publish" the application (to, say, some folder on drive C), either from menu Build or from the project's properties ? Publish. This will create an installer for a ClickOnce application.
- But instead of using the produced installer, find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the
bin\Debug folder below the project file (.csproj).
- Zip that folder (leave out any *.vhost.* files and the
app.publish folder (they are not needed), and the .pdb files unless you foresee debugging directly on your user's system (for example, by remote control)), and provide it to the users.
An added advantage is that, as a ClickOnce application, it does not require administrative privileges to run (if your application follows the normal guidelines for which folders to use for application data, etc.).
As for .NET, you can check for the minimum required version of .NET being installed (or at all) in the application (most users will already have it installed) and present a dialog with a link to the download page on the Microsoft website (or point to one of your pages that could redirect to the Microsoft page - this makes it more robust if the Microsoft URL change). As it is a small utility, you could target .NET 2.0 to reduce the probability of a user to have to install .NET.
It works. We use this method during development and test to avoid having to constantly uninstall and install the application and still being quite close to how the final application will run.
How can I make all images of different height and width the same via CSS?
can i just throw in that if you distort your images too much, ie take them out of a ratio, they may not look right, - a tiny amount is fine, but one way to do this is put the images inside a 'container' and set the container to the 100 x 100, then set your image to overflow none, and set the smallest width to the maximum width of the container, this will crop a bit of your image though,
for example
<h4>Products</h4>
<ul class="products">
<li class="crop">
<img src="ipod.jpg" alt="iPod" />
</li>
</ul>
.crop {
height: 300px;
width: 400px;
overflow: hidden;
}
.crop img {
height: auto;
width: 400px;
}
This way the image will stay the size of its container, but will resize without breaking constraints
How to dump a table to console?
Most pure lua print table functions I've seen have a problem with deep recursion
and tend to cause a stack overflow when going too deep. This print
table function that I've written does not have this problem. It should also be capable of handling really large tables due to the way it handles concatenation. In my personal usage of this function, it outputted 63k lines to file in about a second.
The output also keeps lua syntax and the script can easily be modified
for simple persistent storage by writing the output to file if modified to allow
only number, boolean, string and table data types to be formatted.
function print_table(node)
local cache, stack, output = {},{},{}
local depth = 1
local output_str = "{\n"
while true do
local size = 0
for k,v in pairs(node) do
size = size + 1
end
local cur_index = 1
for k,v in pairs(node) do
if (cache[node] == nil) or (cur_index >= cache[node]) then
if (string.find(output_str,"}",output_str:len())) then
output_str = output_str .. ",\n"
elseif not (string.find(output_str,"\n",output_str:len())) then
output_str = output_str .. "\n"
end
-- This is necessary for working with HUGE tables otherwise we run out of memory using concat on huge strings
table.insert(output,output_str)
output_str = ""
local key
if (type(k) == "number" or type(k) == "boolean") then
key = "["..tostring(k).."]"
else
key = "['"..tostring(k).."']"
end
if (type(v) == "number" or type(v) == "boolean") then
output_str = output_str .. string.rep('\t',depth) .. key .. " = "..tostring(v)
elseif (type(v) == "table") then
output_str = output_str .. string.rep('\t',depth) .. key .. " = {\n"
table.insert(stack,node)
table.insert(stack,v)
cache[node] = cur_index+1
break
else
output_str = output_str .. string.rep('\t',depth) .. key .. " = '"..tostring(v).."'"
end
if (cur_index == size) then
output_str = output_str .. "\n" .. string.rep('\t',depth-1) .. "}"
else
output_str = output_str .. ","
end
else
-- close the table
if (cur_index == size) then
output_str = output_str .. "\n" .. string.rep('\t',depth-1) .. "}"
end
end
cur_index = cur_index + 1
end
if (size == 0) then
output_str = output_str .. "\n" .. string.rep('\t',depth-1) .. "}"
end
if (#stack > 0) then
node = stack[#stack]
stack[#stack] = nil
depth = cache[node] == nil and depth + 1 or depth - 1
else
break
end
end
-- This is necessary for working with HUGE tables otherwise we run out of memory using concat on huge strings
table.insert(output,output_str)
output_str = table.concat(output)
print(output_str)
end
Here is an example:
local t = {
["abe"] = {1,2,3,4,5},
"string1",
50,
["depth1"] = { ["depth2"] = { ["depth3"] = { ["depth4"] = { ["depth5"] = { ["depth6"] = { ["depth7"]= { ["depth8"] = { ["depth9"] = { ["depth10"] = {1000}, 900}, 800},700},600},500}, 400 }, 300}, 200}, 100},
["ted"] = {true,false,"some text"},
"string2",
[function() return end] = function() return end,
75
}
print_table(t)
Output:
{
[1] = 'string1',
[2] = 50,
[3] = 'string2',
[4] = 75,
['abe'] = {
[1] = 1,
[2] = 2,
[3] = 3,
[4] = 4,
[5] = 5
},
['function: 06472B70'] = 'function: 06472A98',
['depth1'] = {
[1] = 100,
['depth2'] = {
[1] = 200,
['depth3'] = {
[1] = 300,
['depth4'] = {
[1] = 400,
['depth5'] = {
[1] = 500,
['depth6'] = {
[1] = 600,
['depth7'] = {
[1] = 700,
['depth8'] = {
[1] = 800,
['depth9'] = {
[1] = 900,
['depth10'] = {
[1] = 1000
}
}
}
}
}
}
}
}
}
},
['ted'] = {
[1] = true,
[2] = false,
[3] = 'some text'
}
}
"python" not recognized as a command
Go to Control Panel / System / "Advanced" tab / Enviromental Variables

Open a new cmd window and try now.
jQuery .scrollTop(); + animation
you can use both CSS class or HTML id, for keeping it symmetric I always use CSS class for example
<a class="btn btn-full js--scroll-to-plans" href="#">I’m hungry</a>
|
|
|
<section class="section-plans js--section-plans clearfix">
$(document).ready(function () {
$('.js--scroll-to-plans').click(function () {
$('body,html').animate({
scrollTop: $('.js--section-plans').offset().top
}, 1000);
return false;})
});
Setting std=c99 flag in GCC
Instead of calling /usr/bin/gcc, use /usr/bin/c99. This is the Single-Unix-approved way of invoking a C99 compiler. On an Ubuntu system, this points to a script which invokes gcc after having added the -std=c99 flag, which is precisely what you want.
Using number_format method in Laravel
If you are using Eloquent, in your model put:
public function getPriceAttribute($price)
{
return $this->attributes['price'] = sprintf('U$ %s', number_format($price, 2));
}
Where getPriceAttribute is your field on database. getSomethingAttribute.
Good examples using java.util.logging
java.util.logging keeps you from having to tote one more jar file around with your application, and it works well with a good Formatter.
In general, at the top of every class, you should have:
private static final Logger LOGGER = Logger.getLogger( ClassName.class.getName() );
Then, you can just use various facilities of the Logger class.
Use Level.FINE for anything that is debugging at the top level of execution flow:
LOGGER.log( Level.FINE, "processing {0} entries in loop", list.size() );
Use Level.FINER / Level.FINEST inside of loops and in places where you may not always need to see that much detail when debugging basic flow issues:
LOGGER.log( Level.FINER, "processing[{0}]: {1}", new Object[]{ i, list.get(i) } );
Use the parameterized versions of the logging facilities to keep from generating tons of String concatenation garbage that GC will have to keep up with. Object[] as above is cheap, on the stack allocation usually.
With exception handling, always log the complete exception details:
try {
...something that can throw an ignorable exception
} catch( Exception ex ) {
LOGGER.log( Level.SEVERE, ex.toString(), ex );
}
I always pass ex.toString() as the message here, because then when I "grep -n" for "Exception" in log files, I can see the message too. Otherwise, it is going to be on the next line of output generated by the stack dump, and you have to have a more advanced RegEx to match that line too, which often gets you more output than you need to look through.
Ajax success event not working
I had the same problem i solved it in that way:
My ajax:
event.preventDefault();
$.ajax('file.php', {
method: 'POST',
dataType: 'json',
contentType: 'application/json',
data: JSON.stringify({tab}),
success: function(php_response){
if (php_response == 'item')
{
console.log('it works');
}
}
})
Ok. The problem is not with json but only php response.
Before: my php response was:
echo 'item';
Now:
$variable = 'item';
echo json.encode($variable);
Now my success working.
PS. Sorry if something is wrong but it is my first comment on this forum :)
Space between two divs
DIVs inherently lack any useful meaning, other than to divide, of course.
Best course of action would be to add a meaningful class name to them, and style their individual margins in CSS.
<h1>Important Title</h1>
<div class="testimonials">...</div>
<div class="footer">...</div>
h1 {margin-bottom: 0.1em;}
div.testimonials {margin-bottom: 0.2em;}
div.footer {margin-bottom: 0;}
No 'Access-Control-Allow-Origin' header is present on the requested resource- AngularJS
This is how it worked for me. For Windows users testing with Bracket and AngularJS
1) Go to your desktop
2) Right click on your desktop and look for "NEW" in the popup drop down dialog box and it will expand
3) Choose Shortcut
4) A dialog box will open
5) Click on Browse and look for Google Chrome.
6) Click Ok->Next->Finish and it will create the google shortcut on your desktop
7) Now Right Click on the Google Chrome icon you just created
8) Click properties
9) Enter this in the target path
"C:\Program Files\Google\Chrome\Application\chrome.exe" --args --disable-web-security
10) Save it
11) Double click on your newly created chrome shortcut and past your link in the address bar and it will work.
Multiple argument IF statement - T-SQL
Not sure what the problem is, this seems to work just fine?
DECLARE @StartDate AS DATETIME
DECLARE @EndDate AS DATETIME
SET @StartDate = NULL
SET @EndDate = NULL
IF (@StartDate IS NOT NULL AND @EndDate IS NOT NULL)
BEGIN
Select 'This works just fine' as Msg
END
Else
BEGIN
Select 'No Lol' as Msg
END
How do I quickly rename a MySQL database (change schema name)?

Why not inherit from List<T>?
While I don't have a complex comparison as most of these answers do, I would like to share my method for handling this situation. By extending IEnumerable<T>, you can allow your Team class to support Linq query extensions, without publicly exposing all the methods and properties of List<T>.
class Team : IEnumerable<Player>
{
private readonly List<Player> playerList;
public Team()
{
playerList = new List<Player>();
}
public Enumerator GetEnumerator()
{
return playerList.GetEnumerator();
}
...
}
class Player
{
...
}
Launch an event when checking a checkbox in Angular2
You can use ngModel like
<input type="checkbox" [ngModel]="checkboxValue" (ngModelChange)="addProp($event)" data-md-icheck/>
To update the checkbox state by updating the property checkboxValue in your code and when the checkbox is changed by the user addProp() is called.
How to print the current time in a Batch-File?
You can use the command time /t for the time and date /t for the date, here is an example:
@echo off
time /t >%tmp%\time.tmp
date /t >%tmp%\date.tmp
set ttime=<%tmp%\time.tmp
set tdate=<%tmp%\date.tmp
del /f /q %tmp%\time.tmp
del /f /q %tmp%\date.tmp
echo Time: %ttime%
echo Date: %tdate%
pause >nul
You can also use the built in variables %time% and %date%, here is another example:
@echo off
echo Time: %time:~0,5%
echo Date: %date%
pause >nul
SQL query to find record with ID not in another table
Keeping in mind the points made in @John Woo's comment/link above, this is how I typically would handle it:
SELECT t1.ID, t1.Name
FROM Table1 t1
WHERE NOT EXISTS (
SELECT TOP 1 NULL
FROM Table2 t2
WHERE t1.ID = t2.ID
)
scrollTop animation without jquery
HTML:
<button onclick="scrollToTop(1000);"></button>
1# JavaScript (linear):
function scrollToTop (duration) {
// cancel if already on top
if (document.scrollingElement.scrollTop === 0) return;
const totalScrollDistance = document.scrollingElement.scrollTop;
let scrollY = totalScrollDistance, oldTimestamp = null;
function step (newTimestamp) {
if (oldTimestamp !== null) {
// if duration is 0 scrollY will be -Infinity
scrollY -= totalScrollDistance * (newTimestamp - oldTimestamp) / duration;
if (scrollY <= 0) return document.scrollingElement.scrollTop = 0;
document.scrollingElement.scrollTop = scrollY;
}
oldTimestamp = newTimestamp;
window.requestAnimationFrame(step);
}
window.requestAnimationFrame(step);
}
2# JavaScript (ease in and out):
function scrollToTop (duration) {
// cancel if already on top
if (document.scrollingElement.scrollTop === 0) return;
const cosParameter = document.scrollingElement.scrollTop / 2;
let scrollCount = 0, oldTimestamp = null;
function step (newTimestamp) {
if (oldTimestamp !== null) {
// if duration is 0 scrollCount will be Infinity
scrollCount += Math.PI * (newTimestamp - oldTimestamp) / duration;
if (scrollCount >= Math.PI) return document.scrollingElement.scrollTop = 0;
document.scrollingElement.scrollTop = cosParameter + cosParameter * Math.cos(scrollCount);
}
oldTimestamp = newTimestamp;
window.requestAnimationFrame(step);
}
window.requestAnimationFrame(step);
}
/*
Explanation:
- pi is the length/end point of the cosinus intervall (see below)
- newTimestamp indicates the current time when callbacks queued by requestAnimationFrame begin to fire.
(for more information see https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame)
- newTimestamp - oldTimestamp equals the delta time
a * cos (bx + c) + d | c translates along the x axis = 0
= a * cos (bx) + d | d translates along the y axis = 1 -> only positive y values
= a * cos (bx) + 1 | a stretches along the y axis = cosParameter = window.scrollY / 2
= cosParameter + cosParameter * (cos bx) | b stretches along the x axis = scrollCount = Math.PI / (scrollDuration / (newTimestamp - oldTimestamp))
= cosParameter + cosParameter * (cos scrollCount * x)
*/
Note:
- Duration in milliseconds (1000ms = 1s)
- Second script uses the cos function. Example curve:

Anaconda Installed but Cannot Launch Navigator
I figured out the reason as to why:
1-There seems to be no navigator icon
2-When conducting the above steps of running the "anaconda-navigator" command in prompt (whether cmd or Anaconda) it yields "anaconda navigator is not recognized as an internal or external command"
This was very frustrating to me as I'd installed the proper version multiple times with no avail.
To solve this problem :
- in the installation process, there will be an advanced options step with 2 selections one of which is unchecked (the top one). Make sure you check it which will add the navigator to the path of your machine variables.
Cheers,
Hossam
How to horizontally center a floating element of a variable width?
The popular answer here does work sometimes, but other times it creates horizontal scroll bars that are tough to deal with - especially when dealing with wide horizontal navigations and large pull down menus. Here is an even lighter-weight version that helps avoid those edge cases:
#wrap {
float: right;
position: relative;
left: -50%;
}
#content {
left: 50%;
position: relative;
}
Proof that it is working!
To more specifically answer your question, it is probably not possible to do without setting up some containing element, however it is very possible to do without specifying a width value. Hope that saves someone out there some headaches!
