You did not post the code generated by the compiler, so there' some guesswork here, but even without having seen it, one can say that this:
test rax, 1
jpe even
... has a 50% chance of mispredicting the branch, and that will come expensive.
The compiler almost certainly does both computations (which costs neglegibly more since the div/mod is quite long latency, so the multiply-add is "free") and follows up with a CMOV. Which, of course, has a zero percent chance of being mispredicted.
<color name="blackColorPrimary">#000001</color> (not #000000)
<item name="android:navigationBarColor" tools:targetApi="lollipop">@color/blackColorPrimary</item>
Problem is that android higher version make trasparent for #000000
I use this one:
LocationManager.requestLocationUpdates(String provider, long minTime, float minDistance, LocationListener listener)
For example, using a 1s interval:
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);
the time is in milliseconds, the distance is in meters.
This automatically calls:
public void onLocationChanged(Location location) {
//Code here, location.getAccuracy(), location.getLongitude() etc...
}
I also had these included in the script but didnt actually use them:
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
In short:
public class GPSClass implements LocationListener {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
Log.i("Message: ","Location changed, " + location.getAccuracy() + " , " + location.getLatitude()+ "," + location.getLongitude());
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);
}
}
setTimeout
returns a timer handle, which you can use to stop the timeout with clearTimeout
.
So for instance:
function setBgPosition() {
var c = 0,
timer = 0;
var numbers = [0, -120, -240, -360, -480, -600, -720];
function run() {
Ext.get('common-spinner').setStyle('background-position', numbers[c++] + 'px 0px');
if (c >= numbers.length) {
c = 0;
}
timer = setTimeout(run, 200);
}
timer = setTimeout(run, 200);
return stop;
function stop() {
if (timer) {
clearTimeout(timer);
timer = 0;
}
}
So you'd use that as:
var stop = setBgPosition();
// ...later, when you're ready to stop...
stop();
Note that rather than having setBgPosition
call itself again, I've just had it set c
back to 0
. Otherwise, this wouldn't work. Also note that I've used 0
as a handle value for when the timeout isn't pending; 0
isn't a valid return value from setTimeout
so it makes a handy flag.
This is also one of the (few) places I think you'd be better off with setInterval
rather than setTimeout
. setInterval
repeats. So:
function setBgPosition() {
var c = 0;
var numbers = [0, -120, -240, -360, -480, -600, -720];
function run() {
Ext.get('common-spinner').setStyle('background-position', numbers[c++] + 'px 0px');
if (c >= numbers.length) {
c = 0;
}
}
return setInterval(run, 200);
}
Used like this:
var timer = setBgPosition();
// ...later, when you're ready to stop...
clearInterval(timer);
All of the above notwithstanding, I'd want to find a way to make setBgPosition
stop things itself, by detecting that some completion condition has been satisfied.
Well, actually I'll have to say David is right with his solution, but there are some topics disturbing me:
ViewModel
, and include the Model as member in the ViewModel
, then you effectively sent your model to the View => this is BADSo how can you create a better coupling?
I would use a tool like AutoMapper
or ValueInjecter to map between ViewModel
and Model.
AutoMapper
does seem to have the better syntax and feel to it, but the current version lacks a
very severe topic: It is not able to perform the mapping from ViewModel
to Model (under certain circumstances like flattening, etc., but this is off topic)
So at present I prefer to use ValueInjecter
.
So you create a ViewModel
with the fields you need in the view.
You add the SelectList items you need as lookups.
And you add them as SelectLists already. So you can query from a LINQ enabled sourc, select the ID and text field and store it as a selectlist:
You gain that you do not have to create a new type (dictionary) as lookup and you just move the new SelectList
from the view to the controller.
// StaffTypes is an IEnumerable<StaffType> from dbContext
// viewModel is the viewModel initialized to copy content of Model Employee
// viewModel.StaffTypes is of type SelectList
viewModel.StaffTypes =
new SelectList(
StaffTypes.OrderBy( item => item.Name )
"StaffTypeID",
"Type",
viewModel.StaffTypeID
);
In the view you just have to call
@Html.DropDownListFor( model => mode.StaffTypeID, model.StaffTypes )
Back in the post element of your method in the controller you have to take a parameter of the type of your ViewModel
. You then check for validation.
If the validation fails, you have to remember to re-populate the viewModel.StaffTypes
SelectList, because this item will be null on entering the post function.
So I tend to have those population things separated into a function.
You just call back return new View(viewModel)
if anything is wrong.
Validation errors found by MVC3 will automatically be shown in the view.
If you have your own validation code you can add validation errors by specifying which field they belong to. Check documentation on ModelState
to get info on that.
If the viewModel
is valid you have to perform the next step:
If it is a create of a new item, you have to populate a model from the viewModel
(best suited is ValueInjecter
). Then you can add it to the EF collection of that type and commit changes.
If you have an update, you get the current db item first into a model. Then you can copy the values from the viewModel
back to the model (again using ValueInjecter
gets you do that very quick).
After that you can SaveChanges
and are done.
Feel free to ask if anything is unclear.
I read that you have a c# background. So a good starting point might be a mixin implementation for .NET.
You might want to check out the codeplex project at http://remix.codeplex.com/

use sep='\s*,\s*'
so that you will take care of spaces in column-names:
transactions = pd.read_csv('transactions.csv', sep=r'\s*,\s*',
header=0, encoding='ascii', engine='python')
alternatively you can make sure that you don't have unquoted spaces in your CSV file and use your command (unchanged)
prove:
print(transactions.columns.tolist())
Output:
['product_id', 'customer_id', 'store_id', 'promotion_id', 'month_of_year', 'quarter', 'the_year', 'store_sales', 'store_cost', 'unit_sales', 'fact_count']
I should like to contribute the modern answer. The SimpleDateFormat
class is notoriously troublesome, and while it was reasonable to fight one’s way through with it when this question was asked six and a half years ago, today we have much better in java.time, the modern Java date and time API. SimpleDateFormat
and its friend Date
are now considered long outdated, so don’t use them anymore.
DateTimeFormatter monthFormatter = DateTimeFormatter.ofPattern("MM/uuuu");
String dateformat = "2012-11-17T00:00:00.000-05:00";
OffsetDateTime dateTime = OffsetDateTime.parse(dateformat);
String monthYear = dateTime.format(monthFormatter);
System.out.println(monthYear);
Output:
11/2012
I am exploiting the fact that your string is in ISO 8601 format, the international standard, and that the classes of java.time parse this format as their default, that is, without any explicit formatter. It’s stil true what the other answers say, you need to parse the original string first, then format the resulting date-time object into a new string. Usually this requires two formatters, only in this case we’re lucky and can do with just one formatter.
SimpleDateFormat.format
cannot accept a String
argument, also when the parameter type is declared to be Object
.mm/yyyy
. Lowercase mm
os for minute of the hour. You need uppercase MM
for month.m
in monthYear
(also because java.time includes a MonthYear
class with uppercase M
, so to avoid confusion).java.time
.30 minutes is 30 * 60 * 1000
miliseconds. Add that to the current date to specify an expiration date 30 minutes in the future.
var date = new Date();
var minutes = 30;
date.setTime(date.getTime() + (minutes * 60 * 1000));
$.cookie("example", "foo", { expires: date });
I suggest not using an array unless you have multiple objects to consider. There isn't anything wrong this statement:
var myMappings = {
"Name": 0.1,
"Phone": 0.1,
"Address": 0.5,
"Zip": 0.1,
"Comments": 0.2
};
for (var col in myMappings) {
alert((myMappings[col] * 100) + "%");
}
Change the property WindowState
to System.Windows.Forms.FormWindowState.Maximized
, in some cases if the older answers doesn't works.
So the window will be maximized, and the other parts are in the other answers.
I recently needed to document how to get a version of it installed, so I've copied my steps here, as the other answers were using different sources from what I recommend, which is Cygwin. I like Cygwin because it is well maintained and provides a wealth of other utilities for Windows. Cygwin also allows you to easily update the versions as needed when vulnerabilities are fixed. Please update your version of OpenSSL often!
Open a Windows Command prompt and check to see if you have OpenSSL installed by entering: openssl version
If you get an error message that the command is NOT recognized, then install OpenSSL by referring to Cygwin following the summary steps below:
Basically, download and run the Cygwin Windows Setup App to install and to update as needed the OpenSSL application:
C:\Program Files\mosquitto>openssl versionOpenSSL 1.1.1f 31 Mar 2020
the difference between "import static com.showboy.Myclass" and "import com.showboy.Myclass"?
The first should generate a compiler error since the static import only works for importing fields or member types. (assuming MyClass is not an inner class or member from showboy)
I think you meant
import static com.showboy.MyClass.*;
which makes all static fields and members from MyClass available in the actual compilation unit without having to qualify them... as explained above

Overview: Use the DbType to set the parameter type.
var parameter = new SqlParameter();
parameter.ParameterName = "@UserID";
parameter.DbType = DbType.Int32;
parameter.Value = userID.ToString();
var command = conn.CreateCommand()
command.Parameters.Add(parameter);
var reader = await command.ExecuteReaderAsync()
In Linux systems, you can use file command. It will give the correct encoding
Sample:
file blah.csv
Output:
blah.csv: ISO-8859 text, with very long lines
If you have more than one column to be converted you can do the following:
df[["col1", "col2", "col3"]] = df[["col1", "col2", "col3"]].apply(pd.to_datetime)
Bonus answer since this use-case brought me here:
In the case where you need to do this as some other user
echo "some output" | sudo -u some_user tee /some/path/some_file
Note that the echo will happen as you and the file write will happen as "some_user" what will NOT work is if you were to run the echo as "some_user" and redirect the output with >> "some_file" because the file redirect will happen as you.
Hint: tee also supports append with the -a flag, if you need to replace a line in a file as another user you could execute sed as the desired user.
A similar approach to @Peter Coppins answer. This, I think, is a bit easier and doesn't require the use of the Orca utility:
Check the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Common\FilesPaths" registry key and make sure the value "mso.dll" is NOT present. If it is present, then Office 64-bit seems to be installed and you should not need this workaround.
Download the Microsoft Access Database Engine 2010 Redistributable.
From the command line, run: AccessDatabaseEngine_x64.exe /passive
(Note: this installer silently crashed or failed for me, so I unzipped the components and ran: AceRedist.msi /passive and that installed fine. Maybe a Windows 10 thing.)

To expand on persistent's answer, and to provide more of the functionality of NUnit, you can do this:
public bool AssertThrows<TException>(
Action action,
Func<TException, bool> exceptionCondition = null)
where TException : Exception
{
try
{
action();
}
catch (TException ex)
{
if (exceptionCondition != null)
{
return exceptionCondition(ex);
}
return true;
}
catch
{
return false;
}
return false;
}
Examples:
// No exception thrown - test fails.
Assert.IsTrue(
AssertThrows<InvalidOperationException>(
() => {}));
// Wrong exception thrown - test fails.
Assert.IsTrue(
AssertThrows<InvalidOperationException>(
() => { throw new ApplicationException(); }));
// Correct exception thrown - test passes.
Assert.IsTrue(
AssertThrows<InvalidOperationException>(
() => { throw new InvalidOperationException(); }));
// Correct exception thrown, but wrong message - test fails.
Assert.IsTrue(
AssertThrows<InvalidOperationException>(
() => { throw new InvalidOperationException("ABCD"); },
ex => ex.Message == "1234"));
// Correct exception thrown, with correct message - test passes.
Assert.IsTrue(
AssertThrows<InvalidOperationException>(
() => { throw new InvalidOperationException("1234"); },
ex => ex.Message == "1234"));
You could use ng-init in an outer div:
<div ng-init="param='value';">
<div ng-controller="BasketController" >
<label>param: {{value}}</label>
</div>
</div>
The parameter will then be available in your controller's scope:
function BasketController($scope) {
console.log($scope.param);
}

Not only strings are immutable reference types. Multi-cast delegates too. That is why it is safe to write
protected void OnMyEventHandler()
{
delegate handler = this.MyEventHandler;
if (null != handler)
{
handler(this, new EventArgs());
}
}
I suppose that strings are immutable because this is the most safe method to work with them and allocate memory. Why they are not Value types? Previous authors are right about stack size etc. I would also add that making strings a reference types allow to save on assembly size when you use the same constant string in the program. If you define
string s1 = "my string";
//some code here
string s2 = "my string";
Chances are that both instances of "my string" constant will be allocated in your assembly only once.
If you would like to manage strings like usual reference type, put the string inside a new StringBuilder(string s). Or use MemoryStreams.
If you are to create a library, where you expect a huge strings to be passed in your functions, either define a parameter as a StringBuilder or as a Stream.
Use ByteArrayInputStream
:
InputStream is = new ByteArrayInputStream(decodedBytes);
Apple simply recommends declaring an isX
getter for stylistic purposes. It doesn't matter whether you customize the getter name or not, as long as you use the dot notation or message notation with the correct name. If you're going to use the dot notation it makes no difference, you still access it by the property name:
@property (nonatomic, assign) BOOL working;
[self setWorking:YES]; // Or self.working = YES;
BOOL working = [self working]; // Or = self.working;
Or
@property (nonatomic, assign, getter=isWorking) BOOL working;
[self setWorking:YES]; // Or self.working = YES;, same as above
BOOL working = [self isWorking]; // Or = self.working;, also same as above

Are you using Hibernate's Query
object, or JPA? For JPA, it should work fine:
String jpql = "from A where name in (:names)";
Query q = em.createQuery(jpql);
q.setParameter("names", l);
For Hibernate's, you'll need to use the setParameterList:
String hql = "from A where name in (:names)";
Query q = s.createQuery(hql);
q.setParameterList("names", l);
There is another option: with
syntax. To use the OPs example, this would look like:
with data as (
select 'value1' name from dual
union all
select 'value2' name from dual
union all
...
select 'value10000+' name from dual)
select field1, field2, field3
from table1 t1
inner join data on t1.name = data.name;
I ran into this problem. In my case I had a list of data in Java where each item had an item_id and a customer_id. I have two tables in the DB with subscriptions to items respective customers. I want to get a list of all subscriptions to the items or to the customer for that item, together with the item id.
I tried three variants:
Option 1: Multiple Selects from Java
Basically, I first
select item_id, token
from item_subs
where (item_id, 0) in ((:item_id_0, 0)...(:item_id_n, 0))
Then
select cus_id, token
from cus_subs
where (cus_id, 0) in ((:cus_id_0, 0)...(:cus_id_n, 0))
Then I build a Map in Java with the cus_id as the key and a list of items as value, and for each found customer subscription I add (to the list returned from the first select) an entry for all relevant items with that item_id. It's much messier code
Option 2: With-syntax
Get everything at once with an SQL like
with data as (
select :item_id_0 item_id, :cus_id_0 cus_id
union all
...
select :item_id_n item_id, :cus_id_n cus_id )
select I.item_id item_id, I.token token
from item_subs I
inner join data D on I.item_id = D.item_id
union all
select D.item_id item_id, C.token token
from cus_subs C
inner join data D on C.cus_id = D.cus_id
Option 3: Temporary table
Create a global temporary table with three fields: rownr (primary key), item_id and cus_id. Insert all the data there then run a very similar select to option 2, but linking in the temporary table instead of the with data
Performance
This is not a fully-scientific performance analysis.
YMMV.
That said, the temporary table option was much slower. As in double so slow. I was getting 14-15 seconds for option 1, 15-16 for option 2 and 30 for option 3.
I'll try them again from the same network as the DB server and check if that changes things when I get the chance.
1.Delete the .idea folder

This worked for me
In addition to the other answers, I often use the git_remote_branch tool. It's an extra install, but it gets you a convenient way to interact with remote branches. In this case, to delete:
grb delete branch
I find that I also use the publish
and track
commands quite often.
If you like the pipe mode, this is the most clean solution:
tar c some-dir | xz > some-dir.tar.xz
It's not necessary to put the f
option in order to deal with files and then to use -
to specify that the file is the standard input. It's also not necessary to specify the -z
option for xz
, because it's default.
It works with gzip
and bzip2
too:
tar c some-dir | gzip > some-dir.tar.gz
or
tar c some-dir | bzip2 > some-dir.tar.bz2
Decompressing is also quite straightforward:
xzcat tarball.tar.xz | tar x
bzcat tarball.tar.bz2 | tar x
zcat tarball.tar.gz | tar x
If you have only tar
archive, you can use cat
:
cat archive.tar | tar x
If you need to list the files only, use tar t
.

I just want to mention a thing, there are many tools can do text processing, e.g. sort, cut, split, join, paste, comm, uniq, column, rev, tac, tr, nl, pr, head, tail.....
they are very handy but you have to learn their options etc.
A lazy way (not the best way) to learn text processing might be: only learn grep , sed and awk. with this three tools, you can solve almost 99% of text processing problems and don't need to memorize above different cmds and options. :)
AND, if you 've learned and used the three, you knew the difference. Actually, the difference here means which tool is good at solving what kind of problem.
a more lazy way might be learning a script language (python, perl or ruby) and do every text processing with it.
1) "container" is a class and not an ID 2) .container - set z-index and display: none in your CSS and not inline unless there is a really good reason to do so. Demo@fiddle
$("#button").click(function() {
$(".container").css("opacity", 0.2);
$("#loading-img").css({"display": "block"});
});
CSS:
#loading-img {
background: url(http://web.bogdanteodoru.com/wp-content/uploads/2012/01/bouncy-css3-loading-animation.jpg) center center no-repeat; /* different for testing purposes */
display: none;
height: 100px; /* for testing purposes */
z-index: 12;
}
And a demo with animated image.
CSS supports text input for colors (i.e. "black" = #000000 "white" = #ffffff) So I think the helpful solution we are looking for here is how can one have PHP take the output from an HTML form text input box and have it tell CSS to use this line of text for background color.
So that when a a user types "blue" into the text field titled "what is your favorite color", they are returned a page with a blue background, or whatever color they happen to type in so long as it is recognized by CSS.
I believe Dan is on the right track, but may need to elaborate for use PHP newbies, when I try this I am returned a green screen no matter what is typed in (I even set this up as an elseif to display a white background if no data is entered in the text field, still green?

The secret is the inline-block

NOTE: This doesn't work properly in IE6/7 if you use "DIV" instead of "SPAN". (see http://www.quirksmode.org/css/display.html)
Without the new

SSL properties are set at the JVM level via system properties. Meaning you can either set them when you run the program (java -D....) Or you can set them in code by doing System.setProperty.
The specific keys you have to set are below:
javax.net.ssl.keyStore- Location of the Java keystore file containing an application process's own certificate and private key. On Windows, the specified pathname must use forward slashes, /, in place of backslashes.
javax.net.ssl.keyStorePassword - Password to access the private key from the keystore file specified by javax.net.ssl.keyStore. This password is used twice: To unlock the keystore file (store password), and To decrypt the private key stored in the keystore (key password).
javax.net.ssl.trustStore - Location of the Java keystore file containing the collection of CA certificates trusted by this application process (trust store). On Windows, the specified pathname must use forward slashes,
/
, in place of backslashes,\
.If a trust store location is not specified using this property, the SunJSSE implementation searches for and uses a keystore file in the following locations (in order):
$JAVA_HOME/lib/security/jssecacerts
$JAVA_HOME/lib/security/cacerts
javax.net.ssl.trustStorePassword - Password to unlock the keystore file (store password) specified by
javax.net.ssl.trustStore
.javax.net.ssl.trustStoreType - (Optional) For Java keystore file format, this property has the value jks (or JKS). You do not normally specify this property, because its default value is already jks.
javax.net.debug - To switch on logging for the SSL/TLS layer, set this property to ssl.
There are two obvious issues with the set literal syntax:
my_set = {'foo', 'bar', 'baz'}
It's not available before Python 2.7
There's no way to express an empty set using that syntax (using {}
creates an empty dict)
Those may or may not be important to you.
The section of the docs outlining this syntax is here.
Look into using the ToString()
method with a specified format.
With hours, 0-padding minutes and seconds:
var ms = 298999;
var d = new Date(1000*Math.round(ms/1000)); // round to nearest second
function pad(i) { return ('0'+i).slice(-2); }
var str = d.getUTCHours() + ':' + pad(d.getUTCMinutes()) + ':' + pad(d.getUTCSeconds());
console.log(str); // 0:04:59
You should check the value of your line of code like adding checking length of it.
if(len(a['Names'].str.contains('Mel'))>0):
print("Name Present")
The ORA-01722 error is pretty straightforward. According to Tom Kyte:
We've attempted to either explicity or implicity convert a character string to a number and it is failing.
However, where the problem is is often not apparent at first. This page helped me to troubleshoot, find, and fix my problem. Hint: look for places where you are explicitly or implicitly converting a string to a number. (I had NVL(number_field, 'string')
in my code.)
Include required imports and you can make ur decision in handleError method Error status will give the error code
import { HttpClient, HttpErrorResponse } from '@angular/common/http';
import {Observable, throwError} from "rxjs/index";
import { catchError, retry } from 'rxjs/operators';
import {ApiResponse} from "../model/api.response";
import { TaxType } from '../model/taxtype.model';
private handleError(error: HttpErrorResponse) {
if (error.error instanceof ErrorEvent) {
// A client-side or network error occurred. Handle it accordingly.
console.error('An error occurred:', error.error.message);
} else {
// The backend returned an unsuccessful response code.
// The response body may contain clues as to what went wrong,
console.error(
`Backend returned code ${error.status}, ` +
`body was: ${error.error}`);
}
// return an observable with a user-facing error message
return throwError(
'Something bad happened; please try again later.');
};
getTaxTypes() : Observable<ApiResponse> {
return this.http.get<ApiResponse>(this.baseUrl).pipe(
catchError(this.handleError)
);
}
There might be a fix to <input type="button">
- but if there is, I don't know it.
Otherwise, a good option seems to be to replace it with a carefully styled a
element.
Example: http://jsfiddle.net/Uka5v/
.button {
background-color: #E3E1B8;
padding: 2px 4px;
font: 13px sans-serif;
text-decoration: none;
border: 1px solid #000;
border-color: #aaa #444 #444 #aaa;
color: #000
}
Upsides include that the a
element will style consistently between different (older) versions of Internet Explorer without any extra work, and I think my link looks nicer than that button :)
In .NET when you pass any parameter to a method, a copy is created. In value types means that any modification you make to the value is at the method scope, and is lost when you exit the method.
When passing a Reference Type, a copy is also made, but it is a copy of a reference, i.e. now you have TWO references in memory to the same object. So, if you use the reference to modify the object, it gets modified. But if you modify the reference itself - we must remember it is a copy - then any changes are also lost upon exiting the method.
As people have said before, an assignment is a modification of the reference, thus is lost:
public void Method1(object obj) {
obj = new Object();
}
public void Method2(object obj) {
obj = _privateObject;
}
The methods above does not modifies the original object.
A little modification of your example
using System;
class Program
{
static void Main(string[] args)
{
TestRef t = new TestRef();
t.Something = "Foo";
DoSomething(t);
Console.WriteLine(t.Something);
}
static public void DoSomething(TestRef t)
{
t = new TestRef();
t.Something = "Bar";
}
}
public class TestRef
{
private string s;
public string Something
{
get {return s;}
set { s = value; }
}
}
You can use:
EQU - equal
NEQ - not equal
LSS - less than
LEQ - less than or equal
GTR - greater than
GEQ - greater than or equal
AVOID USING:
() ! ~ - * / % + - << >> & | = *= /= %= += -= &= ^= |= <<= >>=
I got an stacktrace similar to yours only when building to Lollipop or Marshmallow, and the solution was to disable Advanved profiling.

I know this is question is a year old, but here's some pretty simple code (mostly from this tutorial) that's working well for me:
import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
@IBOutlet weak var imageView: UIImageView!
var imagePicker = UIImagePickerController()
override func viewDidLoad() {
super.viewDidLoad()
self.imagePicker.delegate = self
}
@IBAction func loadImageButtonTapped(sender: AnyObject) {
print("hey!")
self.imagePicker.allowsEditing = false
self.imagePicker.sourceType = .SavedPhotosAlbum
self.presentViewController(imagePicker, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
self.imageView.contentMode = .ScaleAspectFit
self.imageView.image = pickedImage
}
dismissViewControllerAnimated(true, completion: nil)
}
func imagePickerControllerDidCancel(picker: UIImagePickerController) {
self.imagePicker = UIImagePickerController()
dismissViewControllerAnimated(true, completion: nil)
}
.init
/.fini
isn't deprecated. It's still part of the the ELF standard and I'd dare say it will be forever. Code in .init
/.fini
is run by the loader/runtime-linker when code is loaded/unloaded. I.e. on each ELF load (for example a shared library) code in .init
will be run. It's still possible to use that mechanism to achieve about the same thing as with __attribute__((constructor))/((destructor))
. It's old-school but it has some benefits.
.ctors
/.dtors
mechanism for example require support by system-rtl/loader/linker-script. This is far from certain to be available on all systems, for example deeply embedded systems where code executes on bare metal. I.e. even if __attribute__((constructor))/((destructor))
is supported by GCC, it's not certain it will run as it's up to the linker to organize it and to the loader (or in some cases, boot-code) to run it. To use .init
/.fini
instead, the easiest way is to use linker flags: -init & -fini (i.e. from GCC command line, syntax would be -Wl -init my_init -fini my_fini
).
On system supporting both methods, one possible benefit is that code in .init
is run before .ctors
and code in .fini
after .dtors
. If order is relevant that's at least one crude but easy way to distinguish between init/exit functions.
A major drawback is that you can't easily have more than one _init
and one _fini
function per each loadable module and would probably have to fragment code in more .so
than motivated. Another is that when using the linker method described above, one replaces the original _init and _fini
default functions (provided by crti.o
). This is where all sorts of initialization usually occur (on Linux this is where global variable assignment is initialized). A way around that is described here
Notice in the link above that a cascading to the original _init()
is not needed as it's still in place. The call
in the inline assembly however is x86-mnemonic and calling a function from assembly would look completely different for many other architectures (like ARM for example). I.e. code is not transparent.
.init
/.fini
and .ctors
/.detors
mechanisms are similar, but not quite. Code in .init
/.fini
runs "as is". I.e. you can have several functions in .init
/.fini
, but it is AFAIK syntactically difficult to put them there fully transparently in pure C without breaking up code in many small .so
files.
.ctors
/.dtors
are differently organized than .init
/.fini
. .ctors
/.dtors
sections are both just tables with pointers to functions, and the "caller" is a system-provided loop that calls each function indirectly. I.e. the loop-caller can be architecture specific, but as it's part of the system (if it exists at all i.e.) it doesn't matter.
The following snippet adds new function pointers to the .ctors
function array, principally the same way as __attribute__((constructor))
does (method can coexist with __attribute__((constructor)))
.
#define SECTION( S ) __attribute__ ((section ( S )))
void test(void) {
printf("Hello\n");
}
void (*funcptr)(void) SECTION(".ctors") =test;
void (*funcptr2)(void) SECTION(".ctors") =test;
void (*funcptr3)(void) SECTION(".dtors") =test;
One can also add the function pointers to a completely different self-invented section. A modified linker script and an additional function mimicking the loader .ctors
/.dtors
loop is needed in such case. But with it one can achieve better control over execution order, add in-argument and return code handling e.t.a. (In a C++ project for example, it would be useful if in need of something running before or after global constructors).
I'd prefer __attribute__((constructor))/((destructor))
where possible, it's a simple and elegant solution even it feels like cheating. For bare-metal coders like myself, this is just not always an option.

There could be several things causing this and it somewhat depends on what you have set up in your database.
First, you could be using a PK in the table that is also an FK to another table making the relationship 1-1. IN this case you may need to do an update rather than an insert. If you really can have only one address record for an order this may be what is happening.
Next you could be using some sort of manual process to determine the id ahead of time. The trouble with those manual processes is that they can create race conditions where two records gab the same last id and increment it by one and then the second one can;t insert.
Third, you query as it is sent to the database may be creating two records. To determine if this is the case, Run Profiler to see exactly what SQL code you are sending and if ti is a select instead of a values clause, then run the select and see if you have due to the joins gotten some records to be duplicated. IN any even when you are creating code on the fly like this the first troubleshooting step is ALWAYS to run Profiler and see if what got sent was what you expected to be sent.
Take a look at http://dev.mysql.com/doc/refman/5.0/en/declare-handler.html
Basically you declare error handler which will call rollback
START TRANSACTION;
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
ROLLBACK;
EXIT PROCEDURE;
END;
COMMIT;

You get the question-mark-diamond characters when your textfile uses high-ANSI encoding -- meaning it uses characters between 127 and 255. Those characters have the eighth (i.e. the most significant) bit set. When ASP.NET reads the textfile it assumes UTF-8 encoding, and that most significant bit has a special meaning.
You must force ASP.NET to interpret the textfile as high-ANSI encoding, by telling it the codepage is 1252:
String textFilePhysicalPath = System.Web.HttpContext.Current.Server.MapPath("~/textfiles/MyInputFile.txt");
String contents = File.ReadAllText(textFilePhysicalPath, System.Text.Encoding.GetEncoding(1252));
lblContents.Text = contents.Replace("\n", "<br />"); // change linebreaks to HTML
If you're using SSMS (or old school Enterprise Manager) to edit the table directly, press CTRL+0 to add a null.
Try using the property ForeColor. Like this :
TextBox1.ForeColor = Color.Red;
If you have a csv file named 'blah.csv' That looks like
a,b,c,d
1,2,3,4
2,3,4,5
3,4,5,6
you know that you can open the file for reading, and create a DictReader with
blah = open('blah.csv', 'r')
reader= csv.DictReader(blah)
Then, you will be able to get the next line with reader.next()
, which should output
{'a':1,'b':2,'c':3,'d':4}
using it again will produce
{'a':2,'b':3,'c':4,'d':5}
However, at this point if you use blah.seek(0)
, the next time you call reader.next()
you will get
{'a':1,'b':2,'c':3,'d':4}
again.
This seems to be the functionality you're looking for. I'm sure there are some tricks associated with this approach that I'm not aware of however. @Brian suggested simply creating another DictReader. This won't work if you're first reader is half way through reading the file, as your new reader will have unexpected keys and values from wherever you are in the file.
Try
document.head.innerHTML += '<meta http-equiv="X-UA-..." content="IE=edge">'

UIView
siblings are stacked in the order in which they are added to their superview. The UIView
hierarchy methods and properties are there to manage view order. In UIView.h:
@property(nonatomic,readonly) UIView *superview;
@property(nonatomic,readonly,copy) NSArray *subviews;
- (void)removeFromSuperview;
- (void)insertSubview:(UIView *)view atIndex:(NSInteger)index;
- (void)exchangeSubviewAtIndex:(NSInteger)index1 withSubviewAtIndex:(NSInteger)index2;
- (void)addSubview:(UIView *)view;
- (void)insertSubview:(UIView *)view belowSubview:(UIView *)siblingSubview;
- (void)insertSubview:(UIView *)view aboveSubview:(UIView *)siblingSubview;
- (void)bringSubviewToFront:(UIView *)view;
- (void)sendSubviewToBack:(UIView *)view;
The sibling views are ordered back to front in the subviews
array. So the topmost view will be:
[parentView.subviews lastObject];
and bottom view will be:
[parentView.subviews objectAtIndex:0];
Like Kolin Krewinkel said, [parentView bringSubviewToFront:view]
will bring the view to the top, but this is only the case if the views are all siblings in the hierarchy.
If you are talking about the current transaction nesting level, then you would use @@TRANCOUNT
.
If you are talking about transaction isolation level, use DBCC USEROPTIONS
and look for an option of isolation level. If it isn't set, it's read committed.
TRUE
and FALSE
are keywords, and should not be quoted as strings:
INSERT INTO first VALUES (NULL, 'G22', TRUE);
INSERT INTO first VALUES (NULL, 'G23', FALSE);
By quoting them as strings, MySQL will then cast them to their integer equivalent (since booleans are really just a one-byte INT
in MySQL), which translates into zero for any non-numeric string. Thus, you get 0
for both values in your table.
mysql> SELECT CAST('TRUE' AS SIGNED), CAST('FALSE' AS SIGNED), CAST('12345' AS SIGNED);
+------------------------+-------------------------+-------------------------+
| CAST('TRUE' AS SIGNED) | CAST('FALSE' AS SIGNED) | CAST('12345' AS SIGNED) |
+------------------------+-------------------------+-------------------------+
| 0 | 0 | 12345 |
+------------------------+-------------------------+-------------------------+
INT
representation:mysql> SELECT TRUE, FALSE;
+------+-------+
| TRUE | FALSE |
+------+-------+
| 1 | 0 |
+------+-------+
Note also, that I have replaced your double-quotes with single quotes as are more standard SQL string enclosures. Finally, I have replaced your empty strings for id
with NULL
. The empty string may issue a warning.
As with most things you should pick which to use based on the context and what is conceptually the correct way to go. A switch is really saying "pick one of these based on this variables value" but an if statement is just a series of boolean checks.
As an example, if you were doing:
int value = // some value
if (value == 1) {
doThis();
} else if (value == 2) {
doThat();
} else {
doTheOther();
}
This would be much better represented as a switch as it then makes it immediately obviously that the choice of action is occurring based on the value of "value" and not some arbitrary test.
Also, if you find yourself writing switches and if-elses and using an OO language you should be considering getting rid of them and using polymorphism to achieve the same result if possible.
Finally, regarding switch taking longer to type, I can't remember who said it but I did once read someone ask "is your typing speed really the thing that affects how quickly you code?" (paraphrased)

What do you actually want to achieve? What your code does is it tries to connect to a server located at 192.168.1.104:4000
. Is this the address of a server that sends the messages (because this looks like a client-side code)? If I run fake server locally:
$ nc -l 4000
...and change socket address to localhost:4000
, it will work and try to read something from nc
-created server.
ServerSocket
and listen on it:ServerSocket serverSocket = new ServerSocket(4000);
Socket socket = serverSocket.accept();
The second line will block until some other piece of software connects to your machine on port 4000. Then you can read from the returned socket. Look at this tutorial, this is actually a very broad topic (threading, protocols...)

Based on this code (which you provided in response to Alex's answer):
Editable newTxt=(Editable)userName1.getText();
String newString = newTxt.toString();
It looks like you're trying to get the text out of a TextView or EditText. If that's the case then this should work:
String newString = userName1.getText().toString();

Application supports iTunes file sharing
A modified version of @mxsb solution that allows us to define multiple files and in my case these are yml files.
In my application-dev.yml, I added this config that allows me to inject all the yml that have -dev.yml in them. This can be a list of specific files also. "classpath:/test/test.yml,classpath:/test2/test.yml"
application:
properties:
locations: "classpath*:/**/*-dev.yml"
This helps to get a properties map.
@Configuration
public class PropertiesConfig {
private final static Logger LOG = LoggerFactory.getLogger(PropertiesConfig.class);
@Value("${application.properties.locations}")
private String[] locations;
@Autowired
private ResourceLoader rl;
@Bean
Map<String, Properties> myProperties() {
return stream(locations)
.collect(toMap(filename -> filename, this::loadProperties));
}
private Properties loadProperties(final String filename) {
YamlPropertySourceLoader loader = new YamlPropertySourceLoader();
try {
final Resource[] possiblePropertiesResources = ResourcePatternUtils.getResourcePatternResolver(rl).getResources(filename);
final Properties properties = new Properties();
stream(possiblePropertiesResources)
.filter(Resource::exists)
.map(resource1 -> {
try {
return loader.load(resource1.getFilename(), resource1);
} catch (IOException e) {
throw new RuntimeException(e);
}
}).flatMap(l -> l.stream())
.forEach(propertySource -> {
Map source = ((MapPropertySource) propertySource).getSource();
properties.putAll(source);
});
return properties;
} catch (IOException e) {
throw new RuntimeException(e);
}
}
}
However, if like in my case, I wanted to have to split yml files for each profile and load them and inject that directly into spring configuration before beans initialisation.

First I added a to_dict method to my model ;
def to_dict(self):
return {"name": self.woo, "title": self.foo}
Then I have this;
class DjangoJSONEncoder(JSONEncoder):
def default(self, obj):
if isinstance(obj, models.Model):
return obj.to_dict()
return JSONEncoder.default(self, obj)
dumps = curry(dumps, cls=DjangoJSONEncoder)
and at last use this class to serialize my queryset.
def render_to_response(self, context, **response_kwargs):
return HttpResponse(dumps(self.get_queryset()))
This works quite well

Simple solution would be : (Assumption: You want whatever you type inside the textbox to get appended to what is already there in the textarea)
In the onClick event of the < a > tag,write a user-defined function, which does this:
function textType(){
var **str1**=$("#textId1").val();
var **str2**=$("#textId2").val();
$("#textId1").val(str1+str2);
}
(where the ids,textId1- for o/p textArea textId2-for i/p textbox')
Yes; functions (and methods) are first class objects in Python. The following works:
def foo(f):
print "Running parameter f()."
f()
def bar():
print "In bar()."
foo(bar)
Outputs:
Running parameter f().
In bar().
These sorts of questions are trivial to answer using the Python interpreter or, for more features, the IPython shell.
The accepted answer with getParams() is for setting POST body data, but the question in the title asked how to set HTTP headers like User-Agent. As CommonsWare said, you override getHeaders(). Here's some sample code which sets the User-Agent to 'Nintendo Gameboy' and Accept-Language to 'fr':
public void requestWithSomeHttpHeaders() {
RequestQueue queue = Volley.newRequestQueue(this);
String url = "http://www.somewebsite.com";
StringRequest getRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>()
{
@Override
public void onResponse(String response) {
// response
Log.d("Response", response);
}
},
new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub
Log.d("ERROR","error => "+error.toString());
}
}
) {
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("User-Agent", "Nintendo Gameboy");
params.put("Accept-Language", "fr");
return params;
}
};
queue.add(getRequest);
}
Window --> Show View --> Variables
Since ID is auto increment, you can also specify ID=NULL as,
LOAD XML LOCAL INFILE '/pathtofile/file.xml' INTO TABLE my_tablename SET ID=NULL;
Username you get like this:
var userName = HttpContext.Current.Request.LogonUserIdentity?.Name;
If you can tolerate a different kind of placeholder (i.e. %s
in place of {}
) you can use String.format
method for that:
String s = "hello %s!";
s = String.format(s, "world" );
assertEquals(s, "hello world!"); // true
To acomplish the timezone change in Postgres 9.1 you must:
1.- Search in your "timezones" folder in /usr/share/postgresql/9.1/ for the appropiate file, in my case would be "America.txt", in it, search for the closest location to your zone and copy the first letters in the left column.
For example: if you are in "New York" or "Panama" it would be "EST":
# - EST: Eastern Standard Time (Australia)
EST -18000 # Eastern Standard Time (America)
# (America/New_York)
# (America/Panama)
2.- Uncomment the "timezone" line in your postgresql.conf
file and put your timezone as shown:
#intervalstyle = 'postgres'
#timezone = '(defaults to server environment setting)'
timezone = 'EST'
#timezone_abbreviations = 'EST' # Select the set of available time zone
# abbreviations. Currently, there are
# Default
# Australia
3.- Restart Postgres
CommandArgument='<%#Eval("ScrapId").Tostring()+ Eval("UserId")%>
//added the comment function
If the name
column were a JSON array (like '["a","b","c"]'
), then you could extract/unpack it with JSON_TABLE() (available since MySQL 8.0.4):
select t.id, j.name
from mytable t
join json_table(
t.name,
'$[*]' columns (name varchar(50) path '$')
) j;
Result:
| id | name |
| --- | ---- |
| 1 | a |
| 1 | b |
| 1 | c |
| 2 | b |
If you store the values in a simple CSV format, then you would first need to convert it to JSON:
select t.id, j.name
from mytable t
join json_table(
replace(json_array(t.name), ',', '","'),
'$[*]' columns (name varchar(50) path '$')
) j
Result:
| id | name |
| --- | ---- |
| 1 | a |
| 1 | b |
| 1 | c |
| 2 | b |
It has been quite a while since this has been posted. But as of Nov 13, 2012 I can verify that port 465 still works.
Refer to GaryM's answer on this forum. I hope this helps few more people.

The primary key class must define equals and hashCode methods
Another solution cold be:
$value = $arr[count($arr) - 1];
The above will count the amount of array values, substract 1 and then return the value.
Note: This can only be used if your array keys are numeric.
Use urlencode()
rather than trying to implement your own. Be lazy.
In JS, "+" concatenation works by creating a new String
object.
For example, with...
var s = "Hello";
...we have one object s.
Next:
s = s + " World";
Now, s is a new object.
2nd method: String.prototype.concat
@theczechsensation's solution is already half way there.
For those who like to exclude noisy log messages and keep the log to their app only this is the solution:
Add your exclusions to Log Tag like this: ^(?!(eglCodecCommon|tagToExclude))
Add your package name or prefix to Package Name: com.mycompany.
This way it is possible to filter for as many strings you like and keep the log to your package.

Try to set ENV PATH. Add PHP path in to ENV PATH.
In order for this extension to work, there are DLL files that must be available to the Windows system PATH. For information on how to do this, see the FAQ entitled "How do I add my PHP directory to the PATH on Windows". Although copying DLL files from the PHP folder into the Windows system directory also works (because the system directory is by default in the system's PATH), this is not recommended. This extension requires the following files to be in the PATH: libeay32.dll
The YouTube URL in src
must have and use the embed
endpoint instead of watch
, so for instance let’s say you want to embed this YouTube video: https://www.youtube.com/watch?v=P6N9782MzFQ
(browser's URL).
You should use the embed
endpoint, so the URL now should be something like https://www.youtube.com/embed/P6N9782MzFQ
. Use this value as the URL in the src
attribute inside the iframe tag in your HTML code, for example:
<iframe width="853" height="480" src="https://www.youtube.com/embed/P6N9782MzFQ" frameborder="0" allowfullscreen ng-show="showvideo"></iframe>
So just replace https://www.youtube.com/watch?v=
with https://www.youtube.com/embed/
and of course check for your video's ID. In this sample, my video ID is P6N9782MzFQ
.
This is an old question, but is high ranked on Google. I almost can't believe on the highest voted answers, because running a node.js process inside a screen session, with the &
or even with the nohup
flag -- all of them -- are just workarounds.
Specially the screen/tmux solution, which should really be considered an amateur solution. Screen and Tmux are not meant to keep processes running, but for multiplexing terminal sessions. It's fine, when you are running a script on your server and want to disconnect. But for a node.js server your don't want your process to be attached to a terminal session. This is too fragile. To keep things running you need to daemonize the process!
There are plenty of good tools to do that.
PM2: http://pm2.keymetrics.io/
# basic usage
$ npm install pm2 -g
$ pm2 start server.js
# you can even define how many processes you want in cluster mode:
$ pm2 start server.js -i 4
# you can start various processes, with complex startup settings
# using an ecosystem.json file (with env variables, custom args, etc):
$ pm2 start ecosystem.json
One big advantage I see in favor of PM2 is that it can generate the system startup script to make the process persist between restarts:
$ pm2 startup [platform]
Where platform
can be ubuntu|centos|redhat|gentoo|systemd|darwin|amazon
.
forever.js: https://github.com/foreverjs/forever
# basic usage
$ npm install forever -g
$ forever start app.js
# you can run from a json configuration as well, for
# more complex environments or multi-apps
$ forever start development.json
Init scripts:
I'm not go into detail about how to write a init script, because I'm not an expert in this subject and it'd be too long for this answer, but basically they are simple shell scripts, triggered by OS events. You can read more about this here
Docker:
Just run your server in a Docker container with -d
option and, voilá, you have a daemonized node.js server!
Here is a sample Dockerfile (from node.js official guide):
FROM node:argon
# Create app directory
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
# Install app dependencies
COPY package.json /usr/src/app/
RUN npm install
# Bundle app source
COPY . /usr/src/app
EXPOSE 8080
CMD [ "npm", "start" ]
Then build your image and run your container:
$ docker build -t <your username>/node-web-app .
$ docker run -p 49160:8080 -d <your username>/node-web-app
Hope this helps somebody landing on this page. Always use the proper tool for the job. It'll save you a lot of headaches and over hours!
It's really just a coding style. The compiler generates the exact same for both variants.
See also here for the performance question:
Here is a very awesome code to find sqrt and even faster than original sqrt function.
float InvSqrt (float x)
{
float xhalf = 0.5f*x;
int i = *(int*)&x;
i = 0x5f375a86 - (i>>1);
x = *(float*)&i;
x = x*(1.5f - xhalf*x*x);
x = x*(1.5f - xhalf*x*x);
x = x*(1.5f - xhalf*x*x);
x=1/x;
return x;
}
In comprehension, the nested lists iteration should follow the same order than the equivalent imbricated for loops.
To understand, we will take a simple example from NLP. You want to create a list of all words from a list of sentences where each sentence is a list of words.
>>> list_of_sentences = [['The','cat','chases', 'the', 'mouse','.'],['The','dog','barks','.']]
>>> all_words = [word for sentence in list_of_sentences for word in sentence]
>>> all_words
['The', 'cat', 'chases', 'the', 'mouse', '.', 'The', 'dog', 'barks', '.']
To remove the repeated words, you can use a set {} instead of a list []
>>> all_unique_words = list({word for sentence in list_of_sentences for word in sentence}]
>>> all_unique_words
['.', 'dog', 'the', 'chase', 'barks', 'mouse', 'The', 'cat']
or apply list(set(all_words))
>>> all_unique_words = list(set(all_words))
['.', 'dog', 'the', 'chases', 'barks', 'mouse', 'The', 'cat']
I wanted to cover a simple way of doing this with the front end too:
Controller:
public ActionResult Index(int page = 0)
{
const int PageSize = 3; // you can always do something more elegant to set this
var count = this.dataSource.Count();
var data = this.dataSource.Skip(page * PageSize).Take(PageSize).ToList();
this.ViewBag.MaxPage = (count / PageSize) - (count % PageSize == 0 ? 1 : 0);
this.ViewBag.Page = page;
return this.View(data);
}
View:
@* rest of file with view *@
@if (ViewBag.Page > 0)
{
<a href="@Url.Action("Index", new { page = ViewBag.Page - 1 })"
class="btn btn-default">
« Prev
</a>
}
@if (ViewBag.Page < ViewBag.MaxPage)
{
<a href="@Url.Action("Index", new { page = ViewBag.Page + 1 })"
class="btn btn-default">
Next »
</a>
}
If you're looking for an HTML only way of doing this in angular...
<div #myDiv class="my_class" (click)="myDiv.classList.toggle('active')">
Some content
</div>
The important bit is the #myDiv
part.
It's a HTML Node reference, so you can use that variable as if it was assigned to document.querySelector('.my_class')
NOTE: this variable is scope specific, so you can use it in *ngFor
statements
You can install these features on windows server 2012 with powershell using the following commands:
Install-WindowsFeature -Name NET-Framework-Features -IncludeAllSubFeature
Install-WindowsFeature -Name NET-WCF-HTTP-Activation45 -IncludeAllSubFeature
You can get a list of features with the following command:
Get-WindowsFeature | Format-Table
pip install -r requirements.txt
and in the requirements.txt file you put your modules in a list, with one item per line.

I have version 2.0.7 installed on Ubuntu and it defaulted to /var/lib/mongodb/
and that is also what was placed into my /etc/mongodb.conf
file.
It's possible with a lot of work.
Basically, you have to post likes action via the Open Graph API. Then, you can add a custom design to your like button.
But then, you''ll need to keep track yourself of the likes so a returning user will be able to unlike content he liked previously.
Plus, you'll need to ask user to log into your app and ask them the publish_action
permission.
All in all, if you're doing this for an application, it may worth it. For a website where you basically want user to like articles, then this is really to much.
Also, consider that you increase your drop-off rate each time you ask user a permission via a Facebook login.
If you want to see an example, I've recently made an app using the open graph like button, just hover on some photos in the mosaique to see it
Often when you use conditional WHERE clauses you end upp with a vastly inefficient query, which is noticeable for large datasets where indexes are used. A great way to optimize the query for different values of your parameter is to make a different execution plan for each value of the parameter. You can achieve this using OPTION (RECOMPILE)
.
In this example it would probably not make much difference, but say the condition should only be used in one of two cases, then you could notice a big impact.
In this example:
WHERE
DateDropped = 0
AND (
(ISNULL(@JobsOnHold, 0) = 1 AND DateAppr >= 0)
OR
(ISNULL(@JobsOnHold, 0) <> 1 AND DateAppr <> 0)
)
OPTION (RECOMPILE)
Source Parameter Sniffing, Embedding, and the RECOMPILE Options
This is because h1
is a block element, so it will extend across the line (or the width you give).
You can make the border go only around the text by setting display:inline
on the h1
Don't grant control to the user, it's totally unnecessay. Select permission on the database is enough. After you have created the login and the user on master (see above answers):
use YourDatabase
go
create user [YourDomain\YourUser] for login [YourDomain\YourUser] with default_schema=[dbo]
go
alter role [db_datareader] add member [YourDomain\YourUser]
go
The way to make this work is to iterate over the list and cast the elements. This can be done using ConvertAll:
List<A> listOfA = new List<C>().ConvertAll(x => (A)x);
You could also use Linq:
List<A> listOfA = new List<C>().Cast<A>().ToList();
Get and Post methods have nothing to do with the server technology you are using, it works the same in php, asp.net or ruby. GET and POST are part of HTTP protocol. As mark noted, POST is more secure. POST forms are also not cached by the browser. POST is also used to transfer large quantities of data.
git push origin amd_qlp_tester
will work for you. If you just type git push
, then the remote of the current branch is the default value.
Syntax of push looks like this - git push <remote> <branch>
. If you look at your remote in .git/config
file, you will see an entry [remote "origin"]
which specifies url of the repository. So, in the first part of command you will tell Git where to find repository for this project, and then you just specify a branch.
It may be more useful to use a http client library like such as this
There are more things like access denied , document moved etc to handle when dealing with http.
(though, it is unlikely in this case)
The standard way to see if a file exists is with the Test-Path
cmdlet.
Test-Path -path $filename
I thought I had this configured but it turns out I set the URL in the wrong place. I followed the URL provided in the Google error page and added my URL here. Stupid mistake from my part, but easily done. Hope this helps
Specify the Class Card for the constructor-:
void Card::Card(Card::Rank rank, Card::Suit suit) {
And also define the default constructor and destructor.
if you need a init.py file in your folder make a copy of the folder and delete init.py in that one to run your tests it works for local projects. If you need to run test regularly see if you can move your init.py to a separate file.
Here is a slightly different approach to read-only properties, which perhaps should be called write-once properties since they do have to get initialized, don't they? For the paranoid among us who worry about being able to modify properties by accessing the object's dictionary directly, I've introduced "extreme" name mangling:
from uuid import uuid4
class ReadOnlyProperty:
def __init__(self, name):
self.name = name
self.dict_name = uuid4().hex
self.initialized = False
def __get__(self, instance, cls):
if instance is None:
return self
else:
return instance.__dict__[self.dict_name]
def __set__(self, instance, value):
if self.initialized:
raise AttributeError("Attempt to modify read-only property '%s'." % self.name)
instance.__dict__[self.dict_name] = value
self.initialized = True
class Point:
x = ReadOnlyProperty('x')
y = ReadOnlyProperty('y')
def __init__(self, x, y):
self.x = x
self.y = y
if __name__ == '__main__':
try:
p = Point(2, 3)
print(p.x, p.y)
p.x = 9
except Exception as e:
print(e)
I guess you missed to put semi-colon ;

(All answers here are lacking, if your sysadmin changes the systemtime, or your timezone has differing winter- and sommer-times. Therefore...)
On linux use: clock_gettime(CLOCK_MONOTONIC_RAW, &time_variable);
It's not affected if the system-admin changes the time, or you live in a country with winter-time different from summer-time, etc.
#include <stdio.h>
#include <time.h>
#include <unistd.h> /* for sleep() */
int main() {
struct timespec begin, end;
clock_gettime(CLOCK_MONOTONIC_RAW, &begin);
sleep(1); // waste some time
clock_gettime(CLOCK_MONOTONIC_RAW, &end);
printf ("Total time = %f seconds\n",
(end.tv_nsec - begin.tv_nsec) / 1000000000.0 +
(end.tv_sec - begin.tv_sec));
}
man clock_gettime
states:
CLOCK_MONOTONIC
Clock that cannot be set and represents monotonic time since some unspecified starting point. This clock is not affected by discontinuous jumps in the system time
(e.g., if the system administrator manually changes the clock), but is affected by the incremental adjustments performed by adjtime(3) and NTP.
The rules for new
are analogous to what happens when you initialize an object with automatic storage duration (although, because of vexing parse, the syntax can be slightly different).
If I say:
int my_int; // default-initialize ? indeterminate (non-class type)
Then my_int
has an indeterminate value, since it is a non-class type. Alternatively, I can value-initialize my_int
(which, for non-class types, zero-initializes) like this:
int my_int{}; // value-initialize ? zero-initialize (non-class type)
(Of course, I can't use ()
because that would be a function declaration, but int()
works the same as int{}
to construct a temporary.)
Whereas, for class types:
Thing my_thing; // default-initialize ? default ctor (class type)
Thing my_thing{}; // value-initialize ? default-initialize ? default ctor (class type)
The default constructor is called to create a Thing
, no exceptions.
So, the rules are more or less:
{}
) or default-initialized (without {}
). (There is some additional prior zeroing behavior with value-initialization, but the default constructor is always given the final say.){}
used?
These rules translate precisely to new
syntax, with the added rule that ()
can be substituted for {}
because new
is never parsed as a function declaration. So:
int* my_new_int = new int; // default-initialize ? indeterminate (non-class type)
Thing* my_new_thing = new Thing; // default-initialize ? default ctor (class type)
int* my_new_zeroed_int = new int(); // value-initialize ? zero-initialize (non-class type)
my_new_zeroed_int = new int{}; // ditto
my_new_thing = new Thing(); // value-initialize ? default-initialize ? default ctor (class type)
(This answer incorporates conceptual changes in C++11 that the top answer currently does not; notably, a new scalar or POD instance that would end up an with indeterminate value is now technically now default-initialized (which, for POD types, technically calls a trivial default constructor). While this does not cause much practical change in behavior, it does simplify the rules somewhat.)
The same error I am facing in my eclipse and going through above all did not help me out, So here are the steps you can do:
Hope this will help!
In the majority of project there are some implementation of object extending: underscore, jquery, lodash: extend.
There is also pure javascript implementation, that is a part of ECMAscript 6: Object.assign: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign
I did test your code and the only problem I could see was the lack of permission given to the directory you try to write the file in to.
Give "write" permission to the directory you need to put the file. In your case it is the current directory.
Use "chmod" in linux.
Add "Everyone" with "write" enabled to the security tab of the directory if you are in Windows.
You can just use find()
:
let first = array.find(Boolean);
Or if you want the first element even if it is falsy:
let first = array.find(e => true);
Going the extra mile:
If you care about readability but don't want to rely on numeric incidences you could add a first()
-function to Array.protoype
by defining it with Object?.define?Property()
which mitigates the pitfalls of modifying the built-in Array object prototype directly (explained here).
Performance is pretty good (find()
stops after the first element) but it isn't perfect or universally accessible (ES6 only). For more background read @Selays answer.
Object.defineProperty(Array.prototype, 'first', {
value() {
return this.find(e => true); // or this.find(Boolean)
}
});
Then to retrieve the first element you can do:
let array = ['a', 'b', 'c'];
array.first();
> 'a'
Snippet to see it in action:
Object.defineProperty(Array.prototype, 'first', {_x000D_
value() {_x000D_
return this.find(Boolean);_x000D_
}_x000D_
});_x000D_
_x000D_
console.log( ['a', 'b', 'c'].first() );
_x000D_
If you are using windows 10 or windows server 2012, the steps to change the java runtime version is this:
Arrays.sort(numArray);
int middle = ((numArray.length) / 2);
if(numArray.length % 2 == 0){
int medianA = numArray[middle];
int medianB = numArray[middle-1];
median = (medianA + medianB) / 2;
} else{
median = numArray[middle + 1];
}
EDIT: I initially had medianB
setting to middle+1
in the even length arrays, this was wrong due to arrays starting count at 0. I have updated it to use middle-1
which is correct and should work properly for an array with an even length.
This might be late as I think most of us are using BS4. This article explained all the questions you asked in a detailed and simple manner also includes what to do when. The detailed guide to use bs4 or bootstrap

This problem is "best" solved by using an anonymous function to pass-in the jQuery object thusly:
The Anonymous Function Looks Like:
<script type="text/javascript">
(function($) {
// You pass-in jQuery and then alias it with the $-sign
// So your internal code doesn't change
})(jQuery);
</script>
This is JavaScript's method of implementing (poor man's) 'Dependency Injection' when used alongside things like the 'Module Pattern'.
So Your Code Would Look Like:
Of course, you might want to make some changes to your internal code now, but you get the idea.
<script type="text/javascript">
(function($) {
$.fn.pluginbutton = function(options) {
myoptions = $.extend({ left: true });
return this.each(function() {
var focus = false;
if (focus === false) {
this.hover(function() {
this.animate({ backgroundPosition: "0 -30px" }, { duration: 0 });
this.removeClass('VBfocus').addClass('VBHover');
}, function() {
this.animate({ backgroundPosition: "0 0" }, { duration: 0 });
this.removeClass('VBfocus').removeClass('VBHover');
});
}
this.mousedown(function() {
focus = true
this.animate({ backgroundPosition: "0 30px" }, { duration: 0 });
this.addClass('VBfocus').removeClass('VBHover');
}, function() {
focus = false;
this.animate({ backgroundPosition: "0 0" }, { duration: 0 });
this.removeClass('VBfocus').addClass('VBHover');
});
});
}
})(jQuery);
</script>
Something like this might help:
SET Today=%Date:~10,4%%Date:~4,2%%Date:~7,2%
mkdir C:\Test\Backup-%Today%
move C:\Test\Log\*.* C:\Test\Backup-%Today%\
SET Today=
The important part is the first line. It takes the output of the internal DATE
value and parses it into an environmental variable named Today
, in the format CCYYMMDD
, as in '20110407`.
The %Date:~10,4%
says to extract a *substring of the Date
environmental variable 'Thu 04/07/2011' (built in - type echo %Date%
at a command prompt) starting at position 10 for 4 characters (2011
). It then concatenates another substring of Date:
starting at position 4 for 2 chars (04
), and then concats two additional characters starting at position 7 (07
).
*The substring value starting points are 0-based.
You may need to adjust these values depending on the date format in your locale, but this should give you a starting point.
The only way the regex matcher knows you are looking for a digit and not the letter d
is to escape the letter (\d
). To type the regex escape character in java, you need to escape it (so \
becomes \\
). So, there's no way around typing double backslashes for special regex chars.
The mysql_* functions are deprecated and unsafe. The code in your question in vulnerable to injection attacks. It is highly recommended that you use the PDO extension instead, like so:
session_start();
$query = "SELECT 'id' FROM Users WHERE username = :name LIMIT 1";
$statement = $PDO->prepare($query);
$params = array(
'name' => $_GET["username"]
);
$statement->execute($params);
$user_data = $statement->fetch();
$_SESSION['myid'] = $user_data['id'];
Where $PDO
is your PDO object variable. See https://www.php.net/pdo_mysql for more information about PHP and PDO.
Here's a jumpstart on how to connect to your database using PDO:
$database_username = "YOUR_USERNAME";
$database_password = "YOUR_PASSWORD";
$database_info = "mysql:host=localhost;dbname=YOUR_DATABASE_NAME";
try
{
$PDO = new PDO($database_info, $database_username, $database_password);
}
catch(PDOException $e)
{
// Handle error here
}
First of all (as Neil stated), SEH is Microsoft's Structured Exception Handling. It is similar to but not identical to exception processing in C++. In fact, you have to enable C++ Exception Handling if you want it in Visual Studio - the default behavior does not guarantee that local objects are destroyed in all cases! In either case, Exception Handling is not really harder it is just different.
Now for your actual questions.
Do you really write exception safe code?
Yes. I strive for exception safe code in all cases. I evangelize using RAII techniques for scoped access to resources (e.g., boost::shared_ptr
for memory, boost::lock_guard
for locking). In general, consistent usage of RAII and scope guarding techniques will make exception safe code much easier to write. The trick is to learn what exists and how to apply it.
Are you sure your last "production ready" code is exception safe?
No. It is as safe as it is. I can say that I haven't seen a process fault due to an exception in several years of 24/7 activity. I don't expect perfect code, just well-written code. In addition to providing exception safety, the techniques above guarantee correctness in a way that is near impossible to achieve with try
/catch
blocks. If you are catching everything in your top control scope (thread, process, etc.), then you can be sure that you will continue to run in the face of exceptions (most of the time). The same techniques will also help you continue to run correctly in the face of exceptions without try
/catch
blocks everywhere.
Can you even be sure that it is?
Yes. You can be sure by a thorough code audit but no one really does that do they? Regular code reviews and careful developers go a long way to getting there though.
Do you know and/or actually use alternatives that work?
I have tried a few variations over the years such as encoding states in the upper bits (ala HRESULT
s) or that horrible setjmp() ... longjmp()
hack. Both of these break down in practice though in completely different ways.
In the end, if you get into the habit of applying a few techniques and carefully thinking about where you can actually do something in response to an exception, you will end up with very readable code that is exception safe. You can sum this up by following these rules:
try
/catch
when you can do something about a specific exceptionnew
or delete
in codestd::sprintf
, snprintf
, and arrays in general - use std::ostringstream
for formatting and replace arrays with std::vector
and std::string
I can only recommend that you learn how to use exceptions properly and forget about result codes if you plan on writing in C++. If you want to avoid exceptions, you might want to consider writing in another language that either does not have them or makes them safe. If you want to really learn how to fully utilize C++, read a few books from Herb Sutter, Nicolai Josuttis, and Scott Meyers.
Currently accepted answer doesn't work (throws exception) and there are too many workarounds but no complete code. This is obviously wasting lots of people's time because this is a popular question.
Combining Mark Byers' answer and Karol Tyl's answer I wrote full code based on how I want to use the Process.Start method.
I have used it to create progress dialog around git commands. This is how I've used it:
private bool Run(string fullCommand)
{
Error = "";
int timeout = 5000;
var result = ProcessNoBS.Start(
filename: @"C:\Program Files\Git\cmd\git.exe",
arguments: fullCommand,
timeoutInMs: timeout,
workingDir: @"C:\test");
if (result.hasTimedOut)
{
Error = String.Format("Timeout ({0} sec)", timeout/1000);
return false;
}
if (result.ExitCode != 0)
{
Error = (String.IsNullOrWhiteSpace(result.stderr))
? result.stdout : result.stderr;
return false;
}
return true;
}
In theory you can also combine stdout and stderr, but I haven't tested that.
public struct ProcessResult
{
public string stdout;
public string stderr;
public bool hasTimedOut;
private int? exitCode;
public ProcessResult(bool hasTimedOut = true)
{
this.hasTimedOut = hasTimedOut;
stdout = null;
stderr = null;
exitCode = null;
}
public int ExitCode
{
get
{
if (hasTimedOut)
throw new InvalidOperationException(
"There was no exit code - process has timed out.");
return (int)exitCode;
}
set
{
exitCode = value;
}
}
}
public class ProcessNoBS
{
public static ProcessResult Start(string filename, string arguments,
string workingDir = null, int timeoutInMs = 5000,
bool combineStdoutAndStderr = false)
{
using (AutoResetEvent outputWaitHandle = new AutoResetEvent(false))
using (AutoResetEvent errorWaitHandle = new AutoResetEvent(false))
{
using (var process = new Process())
{
var info = new ProcessStartInfo();
info.CreateNoWindow = true;
info.FileName = filename;
info.Arguments = arguments;
info.UseShellExecute = false;
info.RedirectStandardOutput = true;
info.RedirectStandardError = true;
if (workingDir != null)
info.WorkingDirectory = workingDir;
process.StartInfo = info;
StringBuilder stdout = new StringBuilder();
StringBuilder stderr = combineStdoutAndStderr
? stdout : new StringBuilder();
var result = new ProcessResult();
try
{
process.OutputDataReceived += (sender, e) =>
{
if (e.Data == null)
outputWaitHandle.Set();
else
stdout.AppendLine(e.Data);
};
process.ErrorDataReceived += (sender, e) =>
{
if (e.Data == null)
errorWaitHandle.Set();
else
stderr.AppendLine(e.Data);
};
process.Start();
process.BeginOutputReadLine();
process.BeginErrorReadLine();
if (process.WaitForExit(timeoutInMs))
result.ExitCode = process.ExitCode;
// else process has timed out
// but that's already default ProcessResult
result.stdout = stdout.ToString();
if (combineStdoutAndStderr)
result.stderr = null;
else
result.stderr = stderr.ToString();
return result;
}
finally
{
outputWaitHandle.WaitOne(timeoutInMs);
errorWaitHandle.WaitOne(timeoutInMs);
}
}
}
}
}
Solution for Silverlight:
string path = HtmlPage.Document.DocumentUri.GetComponents(UriComponents.SchemeAndServer, UriFormat.Unescaped);
Try something like the following example, quoted from the output of IF /?
on Windows XP:
IF EXIST filename. ( del filename. ) ELSE ( echo filename. missing. )
You can also check for a missing file with IF NOT EXIST
.
The IF
command is quite powerful. The output of IF /?
will reward careful reading. For that matter, try the /?
option on many of the other built-in commands for lots of hidden gems.
There are a few solutions to your problem.
The way with MySQLi would be like this:
<?php
$connection = mysqli_connect('localhost', 'username', 'password', 'database');
To run database queries is also simple and nearly identical with the old way:
<?php
// Old way
mysql_query('CREATE TEMPORARY TABLE `table`', $connection);
// New way
mysqli_query($connection, 'CREATE TEMPORARY TABLE `table`');
Turn off all deprecated warnings including them from mysql_*:
<?php
error_reporting(E_ALL ^ E_DEPRECATED);
The Exact file and line location which needs to be replaced is "/System/Startup.php > line: 2 " error_reporting(E_All); replace with error_reporting(E_ALL ^ E_DEPRECATED);
We're all in agreement that it is a difficult problem for many reasons, but that's precisely the reason to try to make it easier on everybody.
There is a recent module on CPAN, utf8::all, that attempts to "turn on Unicode. All of it".
As has been pointed out, you can't magically make the entire system (outside programs, external web requests, etc.) use Unicode as well, but we can work together to make sensible tools that make doing common problems easier. That's the reason that we're programmers.
If utf8::all doesn't do something you think it should, let's improve it to make it better. Or let's make additional tools that together can suit people's varying needs as well as possible.

you can join both tables even on UPDATE
statements,

SET a.marks = b.marks
FROM tempDataView a
INNER JOIN tempData b
ON a.Name = b.Name
for faster performance, define an INDEX

on both tables.
using SUBQUERY
UPDATE tempDataView
SET marks =
(
SELECT marks
FROM tempData b
WHERE tempDataView.Name = b.Name
)

Thought I would add this in case you are looking at how to do this for a technical interview where they don't want you to use Python's built-in function in
or find
, which is horrible, but does happen:
string = "Samantha"
word = "man"
def find_sub_string(word, string):
len_word = len(word) #returns 3
for i in range(len(string)-1):
if string[i: i + len_word] == word:
return True
else:
return False
I used the following code to apply some external CSS:
boxText = document.createElement("html");
boxText.innerHTML = "<head><link rel='stylesheet' href='style.css'/></head><body>[some html]<body>";
infowindow.setContent(boxText);
infowindow.open(map, marker);
This is not optimal performance-wise, but a pretty straight-forward Linq approach:
string strippedString = new string(
yourString.Where(c => c <= sbyte.MaxValue).ToArray()
);
The downside is that all the "surviving" characters are first put into an array of type char[]
which is then thrown away after the string
constructor no longer uses it.

Whenever possible, I set the field visibility as package-protected so it can be accessed from the test class. I document that using Guava's @VisibleForTesting annotation (in case the next guy wonders why it's not private). This way I don't have to rely on the string name of the field and everything stays type-safe.
I know it goes against standard encapsulation practices we were taught in school. But as soon as there is some agreement in the team to go this way, I found it the most pragmatic solution.
var str = "43215";
console.log("Before : \n string :"+str+"\n Length :"+str.length);
var max = 9;
while(str.length < max ){
str = "0" + str;
}
console.log("After : \n string :"+str+"\n Length :"+str.length);
It worked for me ! To increase the zeroes, update the 'max' variable
Working Fiddle URL : Adding extra zeros in front of a number using jQuery?:
ini_set('memory_limit', '128M');

or

You should use NULL only with pointers. Your function accepts a reference and they can't be NULL.
Write your function just like you would write it in C.
I would suggest writing an extension method for this:
public static IEnumerable<T> Select<T>(this IDataReader reader,
Func<IDataReader, T> projection)
{
while (reader.Read())
{
yield return projection(reader);
}
}
You can then use LINQ's ToList()
method to convert that into a List<T>
if you want, like this:
using (IDataReader reader = ...)
{
List<Customer> customers = reader.Select(r => new Customer {
CustomerId = r["id"] is DBNull ? null : r["id"].ToString(),
CustomerName = r["name"] is DBNull ? null : r["name"].ToString()
}).ToList();
}
I would actually suggest putting a FromDataReader
method in Customer
(or somewhere else):
public static Customer FromDataReader(IDataReader reader) { ... }
That would leave:
using (IDataReader reader = ...)
{
List<Customer> customers = reader.Select<Customer>(Customer.FromDataReader)
.ToList();
}
(I don't think type inference would work in this case, but I could be wrong...)
This problem can also come up when you don't have your constructor immediately call super.
So this will work:
public Employee(String name, String number, Date date)
{
super(....)
}
But this won't:
public Employee(String name, String number, Date date)
{
// an example of *any* code running before you call super.
if (number < 5)
{
number++;
}
super(....)
}
The reason the 2nd example fails is because java is trying to implicitely call
super(name,number,date)
as the first line in your constructor.... So java doesn't see that you've got a call to super going on later in the constructor. It essentially tries to do this:
public Employee(String name, String number, Date date)
{
super(name, number, date);
if (number < 5)
{
number++;
}
super(....)
}
So the solution is pretty easy... Just don't put code before your super call ;-) If you need to initialize something before the call to super, do it in another constructor, and then call the old constructor... Like in this example pulled from this StackOverflow post:
public class Foo
{
private int x;
public Foo()
{
this(1);
}
public Foo(int x)
{
this.x = x;
}
}
I replaced
services.Add(new ServiceDescriptor(typeof(IMyLogger), typeof(MyLogger)));
With
services.AddTransient<IMyLogger, MyLogger>();
And it worked for me.
Just a simple decorator
class overload:
def __init__(self, f):
self.cases = {}
def args(self, *args):
def store_function(f):
self.cases[tuple(args)] = f
return self
return store_function
def __call__(self, *args):
function = self.cases[tuple(type(arg) for arg in args)]
return function(*args)
You can use it like this
@overload
def f():
pass
@f.args(int, int)
def f(x, y):
print('two integers')
@f.args(float)
def f(x):
print('one float')
f(5.5)
f(1, 2)
Modify it to adapt it to your use case.
A clarification of concepts
self/this
argument. However, most languages only do it for the this
argument only. The above decorator extends the idea to multiple parameters.To clear up, assume a static language, and define the functions
void f(Integer x):
print('integer called')
void f(Float x):
print('float called')
void f(Number x):
print('number called')
Number x = new Integer('5')
f(x)
x = new Number('3.14')
f(x)
With static dispatch (overloading) you will see "number called" twice, because x
has been declared as Number
, and that's all overloading cares about. With dynamic dispatch you will see "integer called, float called", because those are the actual types of x
at the time the function is called.

I'm a little late, but, since some time ago in TypeScript you can define the type of callback with
type MyCallback = (KeyboardEvent) => void;
Example of use:
this.addEvent(document, "keydown", (e) => {
if (e.keyCode === 1) {
e.preventDefault();
}
});
addEvent(element, eventName, callback: MyCallback) {
element.addEventListener(eventName, callback, false);
}
add the onclick attribute
<div onclick="myFunction( event );"><span>shanghai</span><span>male</span></div>
To get the cursor to change use css's cursor rule.
div[onclick] {
cursor: pointer;
}
The selector uses an attribute selector which does not work in some versions of IE. If you want to support those versions, add a class to your div.
words = "apple banana apple strawberry banana lemon"
w=words.split()
e=list(set(w))
word_freqs = {}
for i in e:
word_freqs[i]=w.count(i)
print(word_freqs)
Hope this helps!

Here's a bit of a grubby answer that get's to the same solution for vertical scroll views, but (against the ethos of stackoverflow) doesn't answer the question. Instead of using a scrollView, just use a UITableView, drag a normal UIView into the header, and make it as big as you want, you can now scroll the content in storyboard.
.communicate()
writes input (there is no input in this case so it just closes subprocess' stdin to indicate to the subprocess that there is no more input), reads all output, and waits for the subprocess to exit.
The exception EOFError is raised in the child process by raw_input()
(it expected data but got EOF (no data)).
p.stdout.read()
hangs forever because it tries to read all output from the child at the same time as the child waits for input (raw_input()
) that causes a deadlock.
To avoid the deadlock you need to read/write asynchronously (e.g., by using threads or select) or to know exactly when and how much to read/write, for example:
from subprocess import PIPE, Popen
p = Popen(["python", "-u", "1st.py"], stdin=PIPE, stdout=PIPE, bufsize=1)
print p.stdout.readline(), # read the first line
for i in range(10): # repeat several times to show that it works
print >>p.stdin, i # write input
p.stdin.flush() # not necessary in this case
print p.stdout.readline(), # read output
print p.communicate("n\n")[0], # signal the child to exit,
# read the rest of the output,
# wait for the child to exit
Note: it is a very fragile code if read/write are not in sync; it deadlocks.
Beware of block-buffering issue (here it is solved by using "-u" flag that turns off buffering for stdin, stdout in the child).
Boost tuple would be my preferred choice for a generalized system of returning more than one value from a function.
Possible example:
include "boost/tuple/tuple.hpp"
tuple <int,int> divide( int dividend,int divisor )
{
return make_tuple(dividend / divisor,dividend % divisor )
}
From your comments,
the tax amount rounded to the 4th decimal and the total price rounded to the 2nd decimal.
Using the example in the comments, I might foresee a case where you have 400 sales of $1.47. Sales-before-tax would be $588.00, and sales-after-tax would sum to $636.51 (accounting for $48.51 in taxes). However, the sales tax of $0.121275 * 400 would be $48.52.
This was one way, albeit contrived, to force a penny's difference.
I would note that there are payroll tax forms from the IRS where they do not care if an error is below a certain amount (if memory serves, $0.50).
Your big question is: does anybody care if certain reports are off by a penny? If the your specs say: yes, be accurate to the penny, then you should go through the effort to convert to DECIMAL.
I have worked at a bank where a one-penny error was reported as a software defect. I tried (in vain) to cite the software specifications, which did not require this degree of precision for this application. (It was performing many chained multiplications.) I also pointed to the user acceptance test. (The software was verified and accepted.)
Alas, sometimes you just have to make the conversion. But I would encourage you to A) make sure that it's important to someone and then B) write tests to show that your reports are accurate to the degree specified.

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.
Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?
This seems to be related to Unable to install Python libraries
See Dominique Barton's answer:
Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.
On Debian-based systems I'd try:
apt-get update && apt-get upgrade python-pip
On Red Hat Linux-based systems:
yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)
On Mac:
sudo easy_install -U pip
You can also try to update
openssl
separately.
The scalar formatter supports collecting the exponents. The docs are as follows:
class matplotlib.ticker.ScalarFormatter(useOffset=True, useMathText=False, useLocale=None) Bases: matplotlib.ticker.Formatter
Tick location is a plain old number. If useOffset==True and the data range is much smaller than the data average, then an offset will be determined such that the tick labels are meaningful. Scientific notation is used for data < 10^-n or data >= 10^m, where n and m are the power limits set using set_powerlimits((n,m)). The defaults for these are controlled by the axes.formatter.limits rc parameter.
your technique would be:
from matplotlib.ticker import ScalarFormatter
xfmt = ScalarFormatter()
xfmt.set_powerlimits((-3,3)) # Or whatever your limits are . . .
{{ Make your plot }}
gca().xaxis.set_major_formatter(xfmt)
To get the exponent displayed in the format x10^5
, instantiate the ScalarFormatter with useMathText=True
.
You could also use:
xfmt.set_useOffset(10000)
To get a result like this:
For .NET Core 2.2, you can use FormattableString

By my side, using Chrome navigator, I had to use DataView() to read an arrayBuffer
function _arrayBufferToBase64( tabU8A ) {

let lecteur_de_donnees = new DataView(tabU8A);
var len = lecteur_de_donnees.byteLength;

According to this it's just a install and go for Visual Studio 2013:
In fact, installing the C# 6.0 compiler from this release involves little more than installing a Visual Studio 2013 extension, which in turn updates the MSBuild target files.
So just get the files from https://github.com/dotnet/roslyn and you are ready to go.
You do have to know it is an outdated version of the specs implemented there, since they no longer update the package for Visual Studio 2013:
You can also try April's End User Preview, which installs on top of Visual Studio 2013. (note: this VS 2013 preview is quite out of date, and is no longer updated)
So if you do want to use the latest version, you have to download the Visual Studio 2015.
Just use event.getSource()
frim within actionPerformed
Cast it to the component
for Ex, if you need combobox
JComboBox comboBox = (JComboBox) event.getSource();
JTextField txtField = (JTextField) event.getSource();
use appropriate api to get the value,
for Ex.
Object selected = comboBox.getSelectedItem(); etc.
You can also go to the bin folder inside your gradle installation folder and correct the JAVA_HOME parameter in gradle.bat file. In my case, my JAVA_HOME was set to c:\Program files\java\bin The JAVA_HOME in gradle.bat was set to %JAVA_HOME%\bin\java.exe.
I corrected the JAVA_HOME in gradle.bat and it worked.
Thank you!!!
In Snow Leopard and later Mac OS versions, it isn't enough to codesign the gdb
executable.
You have to follow this guide to make it work: http://www.opensource.apple.com/source/lldb/lldb-69/docs/code-signing.txt
The guide explains how to do it for lldb
, but the process is exactly the same for gdb
.
you can use line.seperator
for appending new line in
onInputChange(evt) {
var tgt = evt.target || window.event.srcElement,
files = tgt.files;
if (FileReader && files && files.length) {
var fr = new FileReader();
fr.onload = function () {
var base64 = fr.result;
debugger;
}
fr.readAsDataURL(files[0]);
}
}
Since you are loading in the spans via ajax you will have to attach delegate handlers to the events to catch them as they bubble up.
$(document).on('click','span',function(e){
console.log(e.target.id)
})
you will want to attach the event to the closest static member you can to increase efficiency.
$('#main_div').on('click','span',function(e){
console.log(e.target.id)
})
is better than binding to the document for instance.
This question may help you understand
The HTML Code:-
'<button type="button" id="GetFile">Get File!</button>'
The jQuery Code:-
'$('#GetFile').on('click', function () {
$.ajax({
url: 'https://s3-us-west-2.amazonaws.com/s.cdpn.io/172905/test.pdf',
method: 'GET',
xhrFields: {
responseType: 'blob'
},
success: function (data) {
var a = document.createElement('a');
var url = window.URL.createObjectURL(data);
a.href = url;
a.download = 'myfile.pdf';
document.body.append(a);
a.click();
a.remove();
window.URL.revokeObjectURL(url);
}
});
});'
It targets some specified feature to execute some other codes...
For example:
@media all and (max-width: 600px) {
.navigation {
-webkit-flex-flow: column wrap;
flex-flow: column wrap;
padding: 0;
}
the above snippet say if the device that run this program have screen with 600px or less than 600px width, in this case our program must execute this part .
At least in Xcode 5, this is the thing that solved the problem for me:
Under provisioning profile, select the offending provisioning profile and then select a valid provisioning profile in the pull-down menu.
Those "anchors" that exist solely to provide a click event, but do not actually link to other content, should really be button elements because that's what they really are.
It can be styled like so:
<button style="border:none; background:transparent; cursor: pointer;">Click me</button>
And of course click events can be attached to buttons without worry of the browser jumping to the top, and without adding extraneous javascript such as onclick="return false;" or event.preventDefault() .
The breakeven will depend on the cost of computing the hash. Hash computations can be trivial, or not... :-) There is always the System.Collections.Specialized.HybridDictionary class to help you not have to worry about the breakeven point.
PHP renders HTML and Javascript to send to the client's browser. PHP is a server-side language. This is what allows it do things like INSERT something into a database on the server.
But an alert is rendered by the browser of the client. You would have to work through javascript to get an alert.
Regarding 0xCC
and 0xCD
in particular, these are relics from the Intel 8088/8086 processor instruction set back in the 1980s. 0xCC
is a special case of the software interrupt opcode INT
0xCD
. The special single-byte version 0xCC
allows a program to generate interrupt 3.
Although software interrupt numbers are, in principle, arbitrary, INT 3
was traditionally used for the debugger break or breakpoint function, a convention which remains to this day. Whenever a debugger is launched, it installs an interrupt handler for INT 3
such that when that opcode is executed the debugger will be triggered. Typically it will pause the currently running programming and show an interactive prompt.
Normally, the x86 INT
opcode is two bytes: 0xCD
followed by the desired interrupt number from 0-255. Now although you could issue 0xCD 0x03
for INT 3
, Intel decided to add a special version--0xCC
with no additional byte--because an opcode must be only one byte in order to function as a reliable 'fill byte' for unused memory.
The point here is to allow for graceful recovery if the processor mistakenly jumps into memory that does not contain any intended instructions. Multi-byte instructions aren't suited this purpose since an erroneous jump could land at any possible byte offset where it would have to continue with a properly formed instruction stream.
Obviously, one-byte opcodes work trivially for this, but there can also be quirky exceptions: for example, considering the fill sequence 0xCDCDCDCD
(also mentioned on this page), we can see that it's fairly reliable since no matter where the instruction pointer lands (except perhaps the last filled byte), the CPU can resume executing a valid two-byte x86 instruction CD CD
, in this case for generating software interrupt 205 (0xCD).
Weirder still, whereas CD CC CD CC
is 100% interpretable--giving either INT 3
or INT 204
--the sequence CC CD CC CD
is less reliable, only 75% as shown, but generally 99.99% when repeated as an int-sized memory filler.
For some reason sudo su - jenkins
does not log me to jenkins
user, I ended up using different approach.
I was successful setting the global env variables using using jenkins config.xml
at /var/lib/jenkins/config.xml
(installed in Linux/ RHEL) - without using external plugins.
I simply had to stop jenkins add then add globalNodeProperties
, and then restart.
Example, I'm defining variables APPLICATION_ENVIRONMENT
and SPRING_PROFILES_ACTIVE
to continious_integration
below,
<?xml version='1.0' encoding='UTF-8'?>
<hudson>
<globalNodeProperties>
<hudson.slaves.EnvironmentVariablesNodeProperty>
<envVars serialization="custom">
<unserializable-parents/>
<tree-map>
<default>
<comparator class="hudson.util.CaseInsensitiveComparator"/>
</default>
<int>2</int>
<string>APPLICATION_ENVIRONMENT</string>
<string>continious_integration</string>
<string>SPRING_PROFILES_ACTIVE</string>
<string>continious_integration</string>
</tree-map>
</envVars>
</hudson.slaves.EnvironmentVariablesNodeProperty>
</globalNodeProperties>

I found two potential ways of solving this specific problem:
Use Chosen
Target mozilla browsers using @-moz-document url-prefix()
like so:
@-moz-document url-prefix() {

}
}
You can use Visual Paradigm for UML. This might not be the best paid (it's US$699) product, just as an option if anyone would like to try. It can create class diagram from PHP and vice versa, and not only PHP, there's a bunch of language you can choose such as C#, C++, Ruby, Java, VB.NET, Python, Objective C, Perl, etc. There's also a trial you can check on.
You can do this:
select *
from user_source
where upper(text) like upper('%SOMETEXT%');
Alternatively, SQL Developer has a built-in report to do this under:
View > Reports > Data Dictionary Reports > PLSQL > Search Source Code
The 11G docs for USER_SOURCE are here
The syntax is
EXEC mySchema.myPackage.myProcedure@myRemoteDB( 'someParameter' );
FYI, it looks like the syntax for retrieving the values has changed according to:
http://freemarker.sourceforge.net/docs/ref_builtins_hash.html
<#assign h = {"name":"mouse", "price":50}>
<#assign keys = h?keys>
<#list keys as key>${key} = ${h[key]}; </#list>
You can easily pick image from asset without UIImage(named: "green-square-Retina")
.
Instead use the image object directly from bundle.
Start typing the image name and you will get suggestions with actual image from bundle. It is advisable practice and less prone to error.
See this Stackoverflow answer for reference.
In this particular example, you can use:
#container:hover #cube {
background-color: yellow;
}
This example only works since cube
is a child of container
. For more complicated scenarios, you'd need to use different CSS, or use JavaScript.
Function can be used within a sql statement whereas procedure cannot be used within a sql statement.
Insert, Update and Create statements cannot be included in function but a procedure can have these statements.
Procedure supports transactions but functions do not support transactions.
Function has to return one and only one value (another can be returned by OUT variable) but procedure returns as many data sets and return values.
Execution plans of both functions and procedures are cached, so the performance is same in both the cases.
