In Xcode 4.5.2 goto Product -> Edit Scheme -> and Under the Diagnostics tab check the check box in between Objective C and Enable Zombie Objects and Click on OK
In Xcode 4.x press
(or click Menubar
> Product
> Scheme
> Edit Scheme
)
select the "Diagnostics" tab and click "Enable Zombie Objects":
This turns released objects into NSZombie instances that print console warnings when used again. This is a debugging aid that increases memory use (no object is really released) but improves error reporting.
A typical case is when you over-release an object and you don't know which one:
-[UITableView release]: message sent to deallocated instance
This Xcode setting is ignored when you archive the application for App Store submission. You don't need to touch anything before releasing your application.
Pressing ??R is the same as selecting Product > Run while keeping the Alt key pressed.
Clicking the "Enable Zombie Objects" checkbox is the same as manually adding "NSZombieEnabled = YES" in the section "Environment Variables" of the tab Arguments.
You functionally want this:
#include <sys/time.h>
struct timeval tv1, tv2;
gettimeofday(&tv1, NULL);
/* stuff to do! */
gettimeofday(&tv2, NULL);
printf ("Total time = %f seconds\n",
(double) (tv2.tv_usec - tv1.tv_usec) / 1000000 +
(double) (tv2.tv_sec - tv1.tv_sec));
Note that this measures in microseconds, not just seconds.
Add this to your package.json
:
"browser": {
"[module-name]": false
},
The ng-if
directive, like other directives creates a child scope. See the script below (or this jsfiddle)
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular.min.js"></script>_x000D_
_x000D_
<script>_x000D_
function main($scope) {_x000D_
$scope.testa = false;_x000D_
$scope.testb = false;_x000D_
$scope.testc = false;_x000D_
$scope.obj = {test: false};_x000D_
}_x000D_
</script>_x000D_
_x000D_
<div ng-app >_x000D_
<div ng-controller="main">_x000D_
_x000D_
Test A: {{testa}}<br />_x000D_
Test B: {{testb}}<br />_x000D_
Test C: {{testc}}<br />_x000D_
{{obj.test}}_x000D_
_x000D_
<div>_x000D_
testa (without ng-if): <input type="checkbox" ng-model="testa" />_x000D_
</div>_x000D_
<div ng-if="!testa">_x000D_
testb (with ng-if): <input type="checkbox" ng-model="testb" /> {{testb}}_x000D_
</div>_x000D_
<div ng-if="!someothervar">_x000D_
testc (with ng-if): <input type="checkbox" ng-model="testc" />_x000D_
</div>_x000D_
<div ng-if="!someothervar">_x000D_
object (with ng-if): <input type="checkbox" ng-model="obj.test" />_x000D_
</div>_x000D_
_x000D_
</div>_x000D_
</div>
_x000D_
So, your checkbox changes the testb
inside of the child scope, but not the outer parent scope.
Note, that if you want to modify the data in the parent scope, you'll need to modify the internal properties of an object like in the last div that I added.
db.inventory.find( { dim_cm: { $elemMatch: { $gt: 22, $lt: 30 } } } )
you can use $gt
and $lt
in query.
This is my alias that works both with Python 2 and Python 3 removing all .pyc .pyo
files as well __pycache__
directories recursively.
alias pyclean='find . -name "*.py[co]" -o -name __pycache__ -exec rm -rf {} +'
Try this..
Download the Sqlite Manager jar file here.
Add it to your eclipse > dropins Directory.
Restart eclipse.
Launch the compatible emulator or device
Run your application.
Go to Window > Open Perspective > DDMS >
Choose the running device.
Go to File Explorer tab.
Select the directory called databases under your application's package.
Select the .db file under the database directory.
Then click Sqlite manager icon like this .
Now you're able to see the .db file.

In iOS 8 you need to do two extra things to get location working: Add a key to your Info.plist and request authorization from the location manager asking it to start. There are two Info.plist keys for the new location authorization. One or both of these keys is required. If neither of the keys are there, you can call startUpdatingLocation but the location manager won’t actually start. It won’t send a failure message to the delegate either (since it never started, it can’t fail). It will also fail if you add one or both of the keys but forget to explicitly request authorization. So the first thing you need to do is to add one or both of the following keys to your Info.plist file:
Both of these keys take a string
which is a description of why you need location services. You can enter a string like “Location is required to find out where you are” which, as in iOS 7, can be localized in the InfoPlist.strings file.
Another option (just so you've seen it):
$(function () {
$(".inputs").click(function (e) {
alert(e.target.id);
});
});
HTH.
My gem version 2.0.3 and I was getting the same issue. This command resolved it:
gem install json --platform=ruby --verbose
When you define a function, you also define what info (arguments) that function needs to work. If it is designed to work without any additional info, and you pass it some, you are going to get that error.
Example: Takes no arguments:
def dog
end
Takes arguments:
def cat(name)
end
When you call these, you need to call them with the arguments you defined.
dog #works fine
cat("Fluffy") #works fine
dog("Fido") #Returns ArgumentError (1 for 0)
cat #Returns ArgumentError (0 for 1)

It is possible to handle this using Vavr library
import static io.vavr.API.*;
import static io.vavr.Predicates.*;
Match(variable).of(
Case($(isIn(5, 6, ... , 100)), () -> doSomething()),
Case($(), () -> handleCatchAllCase())
);
This is of course only slight improvement since all cases still need to be listed explicitly. But it is easy to define custom predicate:
public static <T extends Comparable<T>> Predicate<T> isInRange(T lower, T upper) {
return x -> x.compareTo(lower) >= 0 && x.compareTo(upper) <= 0;
}
Match(variable).of(
Case($(isInRange(5, 100)), () -> doSomething()),
Case($(), () -> handleCatchAllCase())
);
Match is an expression so here it returns something like Runnable
instance instead of invoking methods directly. After match is performed Runnable
can be executed.
For further details please see official documentation.
Here's how its done i believe the correct way. It works on Ipad and Iphone as i tested it. We have to create our own customCells by classing a uitableviewcell:
start off in interfaceBuilder ... create a new UIViewcontroller call it customCell (volunteer for a xib while your there) Make sure customCell is a subclass of uitableviewcell
erase all views now and create one view make it the size of a individual cell. make that view subclass customcell. now create two other views (duplicate the first).
Go to your connections inspector and find 2 IBOutlets you can connect to these views now.
-backgroundView -SelectedBackground
connect these to the last two views you just duplicated and dont worry about them. the very first view that extends customCell, put your label and uitextfield inside of it. got into customCell.h and hook up your label and textfield. Set the height of this view to say 75 (height of each cell) all done.
In your customCell.m file make sure the constructor looks something like this:
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
NSArray *nibArray = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
self = [nibArray objectAtIndex:0];
}
return self;
}
Now create a UITableViewcontroller and in this method use the customCell class like this :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
// lets use our customCell which has a label and textfield already installed for us
customCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
//cell = [[[customCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
NSArray *topLevelsObjects = [[NSBundle mainBundle] loadNibNamed:@"NewUserCustomCell" owner:nil options:nil];
for (id currentObject in topLevelsObjects){
if ([currentObject isKindOfClass:[UITableViewCell class]]){
cell = (customCell *) currentObject;
break;
}
}
NSUInteger row = [indexPath row];
switch (row) {
case 0:
{
cell.titleLabel.text = @"First Name"; //label we made (uitextfield also available now)
break;
}
}
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
return 75.0;
}
You can upload artifacts via their native publishing capabilities (e.g. maven deploy, npm publish).
You can also upload artifacts to "raw" repositories via a simple curl request, e.g.
curl --fail -u admin:admin123 --upload-file foo.jar 'http://my-nexus-server.com:8081/repository/my-raw-repo/'
Float has 32 bit (4 bytes) with 8 places accuracy. Double has 64 bit (8 bytes) with 16 places accuracy.
If you need better accuracy, use Double instead of Float.

For me / had to be in a new line.

I ended up combining urlTree
with location.go
const urlTree = this.router.createUrlTree([], {
relativeTo: this.route,
queryParams: {
newParam: myNewParam,
},
queryParamsHandling: 'merge',
});
this.location.go(urlTree.toString());
Not sure if toString
can cause problems, but unfortunately location.go
, seems to be string based.
If you use Sass,
according to the documentation you can customize your default values.
In your case, you can easily override the variable named $modal-lg
in your _custom.scss
file.
You can make auto increment in SQL Modeler. In column properties window Click : General then Tick the box of Auto Increment. After that the auto increment window will be enabled for you.
There's an entire practice that says it's a bad idea to have inline functions/styles. Taking into account you already have an ID for your button, consider
JS
var myvar=15;
function init(){
document.getElementById('EditBanner').onclick=function(){EditBanner(myvar);};
}
window.onload=init;
HTML
<input id="EditBanner" type="button" value="Edit Image" />
ALTER TABLE [table_name] ALTER COLUMN [column_name] varchar(150)
The onclick
attribute on your anchor tag is going to call a client-side function. (This is what you would use if you wanted to call a javascript function when the link is clicked.)
What you want is a server-side control, like the LinkButton
:
<asp:LinkButton ID="lnkTutorial" runat="server" Text="Tutorial" OnClick="displayTutorial_Click"/>
This has an OnClick
attribute that will call the method in your code behind.
Looking further into your code, it looks like you're just trying to open a different tutorial based on access level of the user. You don't need an event handler for this at all. A far better approach would be to just set the end point of your LinkButton
control in the code behind.
protected void Page_Load(object sender, EventArgs e)
{
userinfo = (UserInfo)Session["UserInfo"];
if (userinfo.user == "Admin")
{
lnkTutorial.PostBackUrl = "help/AdminTutorial.html";
}
else
{
lnkTutorial.PostBackUrl = "help/UserTutorial.html";
}
}
Really, it would be best to check that you actually have a user first.
protected void Page_Load(object sender, EventArgs e)
{
if (Session["UserInfo"] != null && ((UserInfo)Session["UserInfo"]).user == "Admin")
{
lnkTutorial.PostBackUrl = "help/AdminTutorial.html";
}
else
{
lnkTutorial.PostBackUrl = "help/UserTutorial.html";
}
}
Use the method DateTimeOffset.ToUnixTimeMilliseconds() It returns the number of milliseconds that have elapsed since 1970-01-01T00:00:00.000Z.
This is only supported with Framework 4.6 or higher
var EPOCH = DateTimeOffset.UtcNow.ToUnixTimeMilliseconds();
It's well documented here DateTimeOffset.ToUnixTimeMilliseconds
The other way out is to use the following
long EPOCH = DateTime.UtcNow.Ticks - new DateTime(1970, 1, 1,0,0,0,0).Ticks;
To get the EPOCH with seconds only you may use
var Epoch = (int)(DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalSeconds;
and convert the Epoch
to DateTime
with the following method
private DateTime Epoch2UTCNow(int epoch)
{
return new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).AddSeconds(epoch);
}
This works in all browsers -
new Date('2001/01/31 12:00:00 AM')
new Date('2001-01-31 12:00:00')
Format: YYYY-MM-DDTHH:mm:ss.sss

Try this
products.sort(function (a, b) {
return a.title.rendered - b.title.rendered;
});
OR
You can import lodash/underscore library, it has many build functions available for manipulating, filtering, sorting the array and all.
Using underscore: (below one is just an example)
import * as _ from 'underscore';
let sortedArray = _.sortBy(array, 'title');
One of the most elegant solution to this problem is to use boost::lexical_cast as @Evgeny Lazin mentioned.
You can write your own Extension method for type String :-
public static string NonBlankValueOf(this string source)
{
return (string.IsNullOrEmpty(source)) ? "0" : source;
}
Now you can use it like with any string type
FooTextBox.Text = strFoo.NonBlankValueOf();
Try using this code for v3:
gMap = new google.maps.Map(document.getElementById('map'));
gMap.setZoom(13); // This will trigger a zoom_changed on the map
gMap.setCenter(new google.maps.LatLng(37.4419, -122.1419));
gMap.setMapTypeId(google.maps.MapTypeId.ROADMAP);
Do you really need to "build" it from javascript or can you simply return the built HTML from PHP and insert it into the DOM?

The error means that your are trying to look up JNDI name, that is not attached to any EJB component - the component with that name does not exist.
As far as dir structure is concerned: you have to create a JAR file with EJB components. As I understand you want to play with EJB 2.X components (at least the linked example suggests that) so the structure of the JAR file should be:
/com/mypackage/MyEJB.class /com/mypackage/MyEJBInterface.class /com/mypackage/etc... etc... java classes /META-INF/ejb-jar.xml /META-INF/jboss.xml
The JAR file is more or less ZIP file with file extension changed from ZIP to JAR.
BTW. If you use JBoss 5, you can work with EJB 3.0, which are much more easier to configure. The simplest component is
@Stateless(mappedName="MyComponentName")
@Remote(MyEJBInterface.class)
public class MyEJB implements MyEJBInterface{
public void bussinesMethod(){
}
}
No ejb-jar.xml, jboss.xml is needed, just EJB JAR with MyEJB and MyEJBInterface compiled classes.
Now in your client code you need to lookup "MyComponentName".
Object oriented C, can be done, I've seen that type of code in production in Korea, and it was the most horrible monster I'd seen in years (this was like last year(2007) that I saw the code). So yes it can be done, and yes people have done it before, and still do it even in this day and age. But I'd recommend C++ or Objective-C, both are languages born from C, with the purpose of providing object orientation with different paradigms.
It's now 2018, and we finally have cheap ways to do something around it...
Indeed, since the 2d context API now has a filter
property, and that this filter property can accept SVGFilters, we can build an SVGFilter that will keep only fully opaque pixels from our drawings, and thus eliminate the default anti-aliasing.
So it won't deactivate antialiasing per se, but provides a cheap way both in term of implementation and of performances to remove all semi-transparent pixels while drawing.
I am not really a specialist of SVGFilters, so there might be a better way of doing it, but for the example, I'll use a <feComponentTransfer>
node to grab only fully opaque pixels.

A major practical difference is its use:
in security scenario
where we always needed a new session, we should use request.getSession(true)
.
request.getSession(false): will return null if no session found.

I normally use the HttpPostedFileBase parameter only in Mvc Controllers. When dealing with ApiControllers try checking the HttpContext.Current.Request.Files property for incoming files instead:
[HttpPost]
public string UploadFile()
{
var file = HttpContext.Current.Request.Files.Count > 0 ?
HttpContext.Current.Request.Files[0] : null;
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(
HttpContext.Current.Server.MapPath("~/uploads"),
fileName
);
file.SaveAs(path);
}
return file != null ? "/uploads/" + file.FileName : null;
}
Css Part is:
CSS:
@media (max-width: 767px) {
// Align text to center.
.text-xs-center {
text-align: center;
}
}
And the HTML part will be ( this text center work only below 767px width )
HTML:
<div class="col-xs-12 col-sm-6 text-right text-xs-center">
<p>
<a href="#"><i class="fa fa-facebook"></i></a>
<a href="#"><i class="fa fa-twitter"></i></a>
<a href="#"><i class="fa fa-google-plus"></i></a>
</p>
</div>
You can also do:
Integer a = '1182-2'.split('-')[0] as Integer
Integer b = '1182-2'.split('-')[1] as Integer
//a=1182 b=2
Sending Data:
First make your serializable data by implement Serializable
to your data class
public class YourDataClass implements Serializable {
String someText="Some text";
}
Then put it into intent
YourDataClass yourDataClass=new YourDataClass();
Intent intent = new Intent(getApplicationContext(),ReceivingActivity.class);
intent.putExtra("value",yourDataClass);
startActivity(intent);
Receiving Data:
YourDataClass yourDataClass=(YourDataClass)getIntent().getSerializableExtra("value");
Try the following:
=IF(OR(E2="in play",E2="pre play",E2="complete",E2="suspended"),
IF(E2="in play",IF(F2="closed",3,IF(F2="suspended",2,IF(ISBLANK(F2),1,-2))),
IF(E2="pre play",IF(ISBLANK(F2),-1,-2),IF(E2="completed",IF(F2="closed",2,-2),
IF(E2="suspended",IF(ISBLANK(F2),3,-2))))),-2)
void func (vector v)
Pass variables by value when the function needs complete isolation from the environment i.e. to prevent the function from modifying the original variable as well as to prevent other threads from modifying its value while the function is being executed.
The downside is the CPU cycles and extra memory spent to copy the object.
void func (const vector& v);
This form emulates pass-by-value behavior while removing the copying overhead. The function gets read access to the original object, but cannot modify its value.
The downside is thread safety: any change made to the original object by another thread will show up inside the function while it's still executing.
void func (vector& v)
Use this when the function has to write back some value to the variable, which will ultimately get used by the caller.
Just like the const reference case, this is not thread-safe.
void func (const vector* vp);
Functionally same as pass by const-reference except for the different syntax, plus the fact that the calling function can pass NULL pointer to indicate it has no valid data to pass.
Not thread-safe.
void func (vector* vp);
Similar to non-const reference. The caller typically sets the variable to NULL when the function is not supposed to write back a value. This convention is seen in many glibc APIs. Example:
void func (string* str, /* ... */) {
if (str != NULL) {
*str = some_value; // assign to *str only if it's non-null
}
}
Just like all pass by reference/pointer, not thread-safe.
1) do
svn revert . --recursive
2) parse output for errors like
"Failed to revert 'dir1/dir2' -- try updating instead."
3) call svn up for each of error directories:
svn up dir1/dir2
You can find your maven files here:
cd ~/.m2
Probably you need to copy settings.xml in your .m2
folder:
cp /usr/local/bin/apache-maven-2.2.1/conf/settings.xml .m2/
If no .m2 folder exists:
mkdir -p ~/.m2
To get the type of fields in struct
package main
import (
"fmt"
"reflect"
)
type testObject struct {
Name string
Age int
Height float64
}
func main() {
tstObj := testObject{Name: "yog prakash", Age: 24, Height: 5.6}
val := reflect.ValueOf(&tstObj).Elem()
typeOfTstObj := val.Type()
for i := 0; i < val.NumField(); i++ {
fieldType := val.Field(i)
fmt.Printf("object field %d key=%s value=%v type=%s \n",
i, typeOfTstObj.Field(i).Name, fieldType.Interface(),
fieldType.Type())
}
}
Output
object field 0 key=Name value=yog prakash type=string
object field 1 key=Age value=24 type=int
object field 2 key=Height value=5.6 type=float64

Use VisualTreeHelper.GetParent or the recursive function below to find the parent window.
public static Window FindParentWindow(DependencyObject child)
{
DependencyObject parent= VisualTreeHelper.GetParent(child);
//CHeck if this is the end of the tree
if (parent == null) return null;
Window parentWindow = parent as Window;
if (parentWindow != null)
{
return parentWindow;
}
else
{
//use recursion until it reaches a Window
return FindParentWindow(parent);
}
}
Create 2 methods which handle the cases. You can instruct the @RequestMapping
annotation to take into account certain parameters whilst mapping the request. That way you can nicely split this into 2 methods.
@RequestMapping (value="/submit/id/{id}", method=RequestMethod.GET,
produces="text/xml", params={"logout"})
public String handleLogout(@PathVariable("id") String id,
@RequestParam("logout") String logout) { ... }
@RequestMapping (value="/submit/id/{id}", method=RequestMethod.GET,
produces="text/xml", params={"name", "password"})
public String handleLogin(@PathVariable("id") String id, @RequestParam("name")
String username, @RequestParam("password") String password,
@ModelAttribute("submitModel") SubmitModel model, BindingResult errors)
throws LoginException {...}
Note that the bb.array() doesn't honor the byte-buffers position, and might be even worse if the bytebuffer you are working on is a slice of some other buffer.
I.e.
byte[] test = "Hello World".getBytes("Latin1");
ByteBuffer b1 = ByteBuffer.wrap(test);
byte[] hello = new byte[6];
b1.get(hello); // "Hello "
ByteBuffer b2 = b1.slice(); // position = 0, string = "World"
byte[] tooLong = b2.array(); // Will NOT be "World", but will be "Hello World".
byte[] world = new byte[5];
b2.get(world); // world = "World"
Which might not be what you intend to do.
If you really do not want to copy the byte-array, a work-around could be to use the byte-buffer's arrayOffset() + remaining(), but this only works if the application supports index+length of the byte-buffers it needs.
In Swift 3.0
let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height
In older swift: Do something like this:
let screenSize: CGRect = UIScreen.mainScreen().bounds
then you can access the width and height like this:
let screenWidth = screenSize.width
let screenHeight = screenSize.height
if you want 75% of your screen's width you can go:
let screenWidth = screenSize.width * 0.75
Swift 4.0
// Screen width.
public var screenWidth: CGFloat {
return UIScreen.main.bounds.width
}
// Screen height.
public var screenHeight: CGFloat {
return UIScreen.main.bounds.height
}
In Swift 5.0
let screenSize: CGRect = UIScreen.main.bounds

You're looking for is called an IDENTITY column:
create table student (
sid integer not null GENERATED ALWAYS AS IDENTITY (START WITH 1 INCREMENT BY 1)
,sname varchar(30)
,PRIMARY KEY (sid)
);
A sequence is another option for doing this, but you need to determine which one is proper for your particular situation. Read this for more information comparing sequences to identity columns.
HTTP is called as a stateless protocol
because each request is executed independently, without any knowledge of the requests that were executed before it, which means once the transaction ends the connection between the browser and the server is also lost.
What makes the protocol stateless
is that in its original design, HTTP is a relatively simple file transfer protocol
:
There was no relationship maintained between one connection and another, even from the same client. This simplifies the contract between client and server, and in many cases minimizes the amount of data that needs to be transferred.
I assume you are meaning "internally" within your application.
you can create your own <a>
tag and insert a url in the href like this
<a href="<?php echo site_url('controller/function/uri') ?>">Link</a>
OR you can use the URL helper this way to generate an <a>
tag
anchor(uri segments, text, attributes)
So... to use it...
<?php echo anchor('controller/function/uri', 'Link', 'class="link-class"') ?>
and that will generate
<a href="http://domain.com/index.php/controller/function/uri" class="link-class">Link</a>
For the additional commented question
I would use my first example
so...
<a href="<?php echo site_url('controller/function') ?>"><img src="<?php echo base_url() ?>img/path/file.jpg" /></a>
for images (and other assets) I wouldn't put the file path within the php, I would just echo the base_url() and then add the path normally.
I needed to see the results of this script and was able to do so by incorporating the below:
var i=0;
function increase()
{
i++;
document.getElementById('boldstuff').innerHTML= +i;
}
<p>var = <b id="boldstuff">0</b></p>
<input type="button" onclick="increase();">
add the "script" tag above all and a closing script tag below the function end curly brace. Returning false caused firefox to hang when I tried it. All other solutions didn't show the result of the increment, in my experience.
A rewrite to help quick understanding:
const hrtime = process.hrtime(); // [0] is seconds, [1] is nanoseconds
let nanoSeconds = (hrtime[0] * 1e9) + hrtime[1]; // 1 second is 1e9 nano seconds
console.log('nanoSeconds: ' + nanoSeconds);
//nanoSeconds: 97760957504895
let microSeconds = parseInt(((hrtime[0] * 1e6) + (hrtime[1]) * 1e-3));
console.log('microSeconds: ' + microSeconds);
//microSeconds: 97760957504
let milliSeconds = parseInt(((hrtime[0] * 1e3) + (hrtime[1]) * 1e-6));
console.log('milliSeconds: ' + milliSeconds);
//milliSeconds: 97760957

If you need just build the project or solution locally then removing the signing might be a dead simple solution as others suggest.
But if you have this error on your automation build server like TeamCity where you build your actual release pieces for deployment or distribution you might want to consider how you can get this cert properly installed to the cert store on the build machine, so that you get a signed packages at the end of the build.
Generally it is not recommenced to check-in/commit any PFX certificates into source control, so how you get this files on your build server during the build process is a bit another question, but sometimes people do have this file stored along with the solution code, so you can find it in the project folder.
All you need to do is just install this certificate under proper account on your build server.
Download PsExec from Windows Sysinternals.
Open a command prompt, and enter the following. It will spawn a new command prompt, running as Local System (assuming that your TeamCity is running under the default Local System account):
> psexec.exe -i -s cmd.exe
In this new command prompt, change to the directory containing the certificate and enter the filename to install (change the name of the file to yours):
> mykey.pfx
The Import Certificate wizard will start up. Click through and select all the suggested defaults.
Run the build.

Json.NET has a JsonPropertyAttribute

[JsonProperty("eighty_min_score")]
public string EightyMinScore { get; set; }
[JsonProperty("home_or_away")]
public string HomeOrAway { get; set; }
[JsonProperty("score ")]
public string Score { get; set; }
[JsonProperty("team_id")]
public string TeamId { get; set; }
}
public class Team
{
public string v1 { get; set; }
[JsonProperty("attributes")]
public TeamScore TeamScores { get; set; }
}
public class RootObject
{
public List<Team> Team { get; set; }
}

Your code is almost right! You are right, you are just missing one step. When you read in the file, you are reading it as a string; but you want to turn the string back into a dictionary.
The error message you saw was because self.whip
was a string, not a dictionary.
I first wrote that you could just feed the string into dict()
but that doesn't work! You need to do something else.
Here is the simplest way: feed the string into eval()
. Like so:
def reading(self):
s = open('deed.txt', 'r').read()
self.whip = eval(s)
You can do it in one line, but I think it looks messy this way:
def reading(self):
self.whip = eval(open('deed.txt', 'r').read())
But eval()
is sometimes not recommended. The problem is that eval()
will evaluate any string, and if someone tricked you into running a really tricky string, something bad might happen. In this case, you are just running eval()
on your own file, so it should be okay.
But because eval()
is useful, someone made an alternative to it that is safer. This is called literal_eval
and you get it from a Python module called ast
.
import ast
def reading(self):
s = open('deed.txt', 'r').read()
self.whip = ast.literal_eval(s)
ast.literal_eval()
will only evaluate strings that turn into the basic Python types, so there is no way that a tricky string can do something bad on your computer.
Actually, best practice in Python is to use a with
statement to make sure the file gets properly closed. Rewriting the above to use a with
statement:
import ast
def reading(self):
with open('deed.txt', 'r') as f:
s = f.read()
self.whip = ast.literal_eval(s)
In the most popular Python, known as "CPython", you usually don't need the with
statement as the built-in "garbage collection" features will figure out that you are done with the file and will close it for you. But other Python implementations, like "Jython" (Python for the Java VM) or "PyPy" (a really cool experimental system with just-in-time code optimization) might not figure out to close the file for you. It's good to get in the habit of using with
, and I think it makes the code pretty easy to understand.
If you are really about to work on multi-gigabyte text files then do not use PowerShell. Even if you find a way to read it faster processing of huge amount of lines will be slow in PowerShell anyway and you cannot avoid this. Even simple loops are expensive, say for 10 million iterations (quite real in your case) we have:
# "empty" loop: takes 10 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) {} }
# "simple" job, just output: takes 20 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) { $i } }
# "more real job": 107 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) { $i.ToString() -match '1' } }
UPDATE: If you are still not scared then try to use the .NET reader:
$reader = [System.IO.File]::OpenText("my.log")
try {
for() {
$line = $reader.ReadLine()
if ($line -eq $null) { break }
# process the line
$line
}
}
finally {
$reader.Close()
}
UPDATE 2
There are comments about possibly better / shorter code. There is nothing wrong with the original code with for
and it is not pseudo-code. But the shorter (shortest?) variant of the reading loop is
$reader = [System.IO.File]::OpenText("my.log")
while($null -ne ($line = $reader.ReadLine())) {
$line
}
yourTable.ImportRow(dataRow);
It's because the row you're copying doesn't have the same TableName
:
For example, try:
Table1.TableName = "Table1";
Table2.TableName = "Table2";
From my own javascript function to toggle Play/Pause - since I'm handling a radio stream, I wanted it to clear the buffer so that the listener does not end up coming out of sync with the radio station.
function playStream() {
var player = document.getElementById('player');
(player.paused == true) ? toggle(0) : toggle(1);
}
function toggle(state) {
var player = document.getElementById('player');
var link = document.getElementById('radio-link');
var src = "http://192.81.248.91:8159/;";
switch(state) {
case 0:
player.src = src;
player.load();
player.play();
link.innerHTML = 'Pause';
player_state = 1;
break;
case 1:
player.pause();
player.currentTime = 0;
player.src = '';
link.innerHTML = 'Play';
player_state = 0;
break;
}
}
Turns out, just clearing the currentTime doesn't cut it under Chrome, needed to clear the source too and load it back in. Hope this helps.
In case you want a quicker (but still very clean) way of achieving it for a personal purpose (for instance if you want to build a specific project having some strong requirements concerning the version of the compiler), just follow the following steps:
echo $PATH
and look for a personal directory having a very high priority (in my case, I have ~/.local/bin
);For instance:
ln -s /usr/bin/gcc-WHATEVER ~/.local/bin/gcc
ln -s /usr/bin/g++-WHATEVER ~/.local/bin/g++
Of course, this will work for a single user (it isn't a system wide solution), but on the other hand I don't like to change too many things in my installation.
An easier way to solve this issues would be to right click the name of your database, choose "New Query", type " exec sp_changedbowner 'sa' " and execute the query. Then you'll be good to go.

You get this error message if a Python file was closed from "the outside", i.e. not from the file object's close()
method:
>>> f = open(".bashrc")
>>> os.close(f.fileno())
>>> del f
close failed in file object destructor:
IOError: [Errno 9] Bad file descriptor
The line del f
deletes the last reference to the file object, causing its destructor file.__del__
to be called. The internal state of the file object indicates the file is still open since f.close()
was never called, so the destructor tries to close the file. The OS subsequently throws an error because of the attempt to close a file that's not open.
Since the implementation of os.system()
does not create any Python file objects, it does not seem likely that the system()
call is the origin of the error. Maybe you could show a bit more code?
I didn't like the alias solution for my purposes. For one, it didn't work for setting export EDITOR="emacs -nw"
.
But you can pass --without-x
to configure and then just the regular old Emacs will always open in terminal.
curl http://gnu.mirrors.hoobly.com/emacs/emacs-25.3.tar.xz
tar -xvzf emacs-25.3.tar.xz && cd emacs-25.3
./configure --without-x
make && sudo make install
Assuming you really mean easiest and are not necessarily looking for a way to do this programmatically, you can do this:
Add, if not already there, a row of "column Musicians" to the spreadsheet. That is, if you have data in columns such as:
Rory Gallagher Guitar
Gerry McAvoy Bass
Rod de'Ath Drums
Lou Martin Keyboards
Donkey Kong Sioux Self-Appointed Semi-official Stomper
Note: you might want to add "Musician" and "Instrument" in row 0 (you might have to insert a row there)
Save the file as a CSV file.
Copy the contents of the CSV file to the clipboard
Verify that the "First row is column names" checkbox is checked
Paste the CSV data into the content area
Mash the "Convert CSV to JSON" button
With the data shown above, you will now have:
[
{
"MUSICIAN":"Rory Gallagher",
"INSTRUMENT":"Guitar"
},
{
"MUSICIAN":"Gerry McAvoy",
"INSTRUMENT":"Bass"
},
{
"MUSICIAN":"Rod D'Ath",
"INSTRUMENT":"Drums"
},
{
"MUSICIAN":"Lou Martin",
"INSTRUMENT":"Keyboards"
}
{
"MUSICIAN":"Donkey Kong Sioux",
"INSTRUMENT":"Self-Appointed Semi-Official Stomper"
}
]
With this simple/minimalistic data, it's probably not required, but with large sets of data, it can save you time and headache in the proverbial long run by checking this data for aberrations and abnormalcy.
Go here: http://jsonlint.com/
Paste the JSON into the content area
Pres the "Validate" button.
If the JSON is good, you will see a "Valid JSON" remark in the Results section below; if not, it will tell you where the problem[s] lie so that you can fix it/them.
On Linux you should be looking at using epoll for async I/O. It might also be worth fine-tuning socket-buffers to not waste too much kernel space per connection.

Why not change the constructor on Production
to let you pass in a reference at construction time:
public class Meter
{
private int _powerRating = 0;
private Production _production;
public Meter()
{
_production = new Production(this);
}
}
In the Production
constructor you can assign this to a private field or a property. Then Production
will always have access to is parent.
Hi you can create a customized build on bootstrap, just change the font name in the following pages
Bootstrap 2.3.2 http://getbootstrap.com/2.3.2/customize.html#variables
Bootstrap 3 http://getbootstrap.com/customize/#less-variables
After that, make sure to use proper @font-face in a css file and link that to your page. Or you could use font kit generators.
To make the dump to a source code control system that little bit faster, you can see which objects have changed since last time by using the version information in sysobjects.
Setup: Create a table in each database you want to check incrementally to hold the version information from the last time you checked it (empty on the first run). Clear this table if you want to re-scan your whole data structure.
IF ISNULL(OBJECT_ID('last_run_sysversions'), 0) <> 0 DROP TABLE last_run_sysversions
CREATE TABLE last_run_sysversions (

id int, base_schema_ver int,
schema_ver int,
type char(2)
)
Normal running mode: You can take the results from this sql, and generate sql scripts for just the ones you're interested in, and put them into a source control of your choice.
IF ISNULL(OBJECT_ID('tempdb.dbo.#tmp'), 0) <> 0 DROP TABLE #tmp
CREATE TABLE #tmp (

One thing that confused me a little bit with this command is that if redis-cli
fails to connect using the passed connection string it will still put you in the redis-cli
shell, i.e:
redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected>
You'll then need to exit
to get yourself out of the shell. I wasn't paying much attention here and kept passing in new redis-cli
commands wondering why the command wasn't using my passed connection string.
- Where does
user.id
go afterpassport.serializeUser
has been called?
The user id (you provide as the second argument of the done
function) is saved in the session and is later used to retrieve the whole object via the deserializeUser
function.
serializeUser
determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}
. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}
- We are calling
passport.deserializeUser
right after it where does it fit in the workflow?
The first argument of deserializeUser
corresponds to the key of the user object that was given to the done
function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc).
In deserializeUser
that key is matched with the in memory array / database or any data resource.
The fetched object is attached to the request object as req.user

In a modern browser with ECMAScript 5.1 / Array.prototype.map
, you can also use
jQuery._data(DOCUMENTELEMENT,'events')["EVENT_NAME"].map(function(elem){return elem.handler;});
in your browser console, which will print the source of the handlers, comma delimited. Useful for glancing at what all is running on a particular event.
If DAO
use
RS.Move 0, RS.LastModified
lngID = RS!AutoNumberFieldName
If ADO
use
cn.Execute "INSERT INTO TheTable.....", , adCmdText + adExecuteNoRecords
Set rs = cn.Execute("SELECT @@Identity", , adCmdText)
Debug.Print rs.Fields(0).Value
cn
being a valid ADO connection, @@Identity
will return the last
Identity
(Autonumber) inserted on this connection.
Note that @@Identity
might be troublesome because the last generated value may not be the one you are interested in. For the Access database engine, consider a VIEW
that joins two tables, both of which have the IDENTITY
property, and you INSERT INTO
the VIEW
. For SQL Server, consider if there are triggers that in turn insert records into another table that also has the IDENTITY
property.
BTW DMax
would not work as if someone else inserts a record just after you've inserted one but before your Dmax
function finishes excecuting, then you would get their record.
Swift uses the same cocoa-touch API. You can call all the same methods, but they will use Swift's syntax. In this example you can do something like this:
self.simpleLabel.text = "message"
Note the setText method isn't available. Setting the label's text with = will automatically call the setter in swift.
I found all the previous answers too much complicated. I had the need to store an array of some ints as a property, and found the ObjC requirement of using a NSArray an unneeded complication of my software.
So I used this:
typedef struct my10ints {
int arr[10];
} my10ints;
@interface myClasss : NSObject
@property my10ints doubleDigits;
@end
This compiles cleanly using Xcode 6.2.
My intention was to use it like this:
myClass obj;
obj.doubleDigits.arr[0] = 4;
HOWEVER, this does not work. This is what it produces:
int i = 4;
myClass obj;
obj.doubleDigits.arr[0] = i;
i = obj.doubleDigits.arr[0];
// i is now 0 !!!
The only way to use this correctly is:
int i = 4;
myClass obj;
my10ints ints;
ints = obj.doubleDigits;
ints.arr[0] = i;
obj.doubleDigits = ints;
i = obj.doubleDigits.arr[0];
// i is now 4
and so, defeats completely my point (avoiding the complication of using a NSArray).
if you are using emulator to run your app for local server. mention the local ip
as 10.0.2.2
and have to give Internet permission into your app :
<uses-permission android:name="android.permission.INTERNET" />
Sorry, it's really quite hard to do this...
I would suggest that you politely ask them to not use your content (if your content is copyrighted).
If it is and they don't take it down, then you can take furthur action and send them a cease and desist letter.
Generally, whatever you do to prevent scraping will probably end up with a more negative effect, e.g. accessibility, bots/spiders, etc.
resultString = subjectString.replaceAll("[^.\\d]", "");
will remove all characters except digits and the dot from your string.
To make it locale-aware, you might want to use getDecimalSeparator()
from java.text.DecimalFormatSymbols
. I don't know Java, but it might look like this:
sep = getDecimalSeparator()
resultString = subjectString.replaceAll("[^"+sep+"\\d]", "");
Here's an example that actually filters for BIN files. Also Windows now want you to save files to user locations, not system locations, so here's an example (you can use intellisense to browse the other options):
var saveFileDialog = new Microsoft.Win32.SaveFileDialog()
{
DefaultExt = "*.xml",
Filter = "BIN Files (*.bin)|*.bin",
InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments),
};
var result = saveFileDialog.ShowDialog();
if (result != null && result == true)
{
// Save the file here
}
I don't think that x[[1,3]][:,[1,3]]
is hardly readable. If you want to be more clear on your intent, you can do:
a[[1,3],:][:,[1,3]]
I am not an expert in slicing but typically, if you try to slice into an array and the values are continuous, you get back a view where the stride value is changed.
e.g. In your inputs 33 and 34, although you get a 2x2 array, the stride is 4. Thus, when you index the next row, the pointer moves to the correct position in memory.
Clearly, this mechanism doesn't carry well into the case of an array of indices. Hence, numpy will have to make the copy. After all, many other matrix math function relies on size, stride and continuous memory allocation.
I know this question was long ago but I found no proper explanation and solution, so hopefully, my answer is useful :)
Assuming you install Docker Toolbox on Windows, both docker
and docker-machine
commands will be available. Often, people get confused when to use either of these.
The docker
commands are used only within a virtual machine to manage images. The docker-machine
commands are used on the host to manage the Linux VMs.
So, please use docker-machine
commands on your Windows machine. Use docker
command inside your VM. To use the docker
commands, for example, docker ps
, you either can open Docker Quickstart Terminal or run these on your cmd/bash/PowerShell:
docker-machine run default
/assuming default is your Linux VM/
docker-machine ssh default
This will start boot2docker and you will see the docker icon on the command line. Then you can use docker
commands.
Good luck :)
Getting the address of an arbitrary object in .NET is not possible, but can be done if you change the source code and use mono. See instructions here: Get Memory Address of .NET Object (C#)
You just need to put your war file in webapps and then start your server.
it will get deployed.
otherwise you can also use tomcat manager a webfront to upload & deploy your war remotely.
You can actually just use os module to do both:
import os #os module imported here
location = os.getcwd() # get present working directory location here
counter = 0 #keep a count of all files found
csvfiles = [] #list to store all csv files found at location
filebeginwithhello = [] # list to keep all files that begin with 'hello'
otherfiles = [] #list to keep any other file that do not match the criteria
for file in os.listdir(location):
try:
if file.endswith(".csv"):
print "csv file found:\t", file
csvfiles.append(str(file))
counter = counter+1
elif file.startswith("hello") and file.endswith(".csv"): #because some files may start with hello and also be a csv file
print "csv file found:\t", file
csvfiles.append(str(file))
counter = counter+1
elif file.startswith("hello"):
print "hello files found: \t", file
filebeginwithhello.append(file)
counter = counter+1
else:
otherfiles.append(file)
counter = counter+1
except Exception as e:
raise e
print "No files found here!"
print "Total files found:\t", counter
Now you have not only listed all the files in a folder but also have them (optionally) sorted by starting name, file type and others. Just now iterate over each list and do your stuff.
<a href="javascript:call_func();">...</a>
where the function then has to return false so that the browser doesn't go to another page.
But I'd recommend to use jQuery (with $(...).click(function () {}))
)
Using MySql, the SqlFunctions.StringConvert
didn't work for me. Since I use SelectListItem
in 20+ places in my project, I wanted a solution that work without contorting the 20+ LINQ statements. My solution was to sub-class SelectedListItem
in order to provide an integer setter, which moves type conversion away from LINQ. Obviously, this solution is difficult to generalize, but was quite helpful for my specific project.
To use, create the following type and use in your LINQ query in place of SelectedListItem
and use IntValue in place of Value.
public class BtoSelectedListItem : SelectListItem
{
public int IntValue
{
get { return string.IsNullOrEmpty(Value) ? 0 : int.Parse(Value); }
set { Value = value.ToString(); }
}
}
I have resolved issue with the help of this link http://www.bootply.com/122726. hopefully will help you

I know this question was already answered, but this is what I use:
using (FileStream fStream = File.OpenRead(filename)) {
return GetHash<MD5>(fStream)
}
Where GetHash:
public static String GetHash<T>(Stream stream) where T : HashAlgorithm {
StringBuilder sb = new StringBuilder();
MethodInfo create = typeof(T).GetMethod("Create", new Type[] {});
using (T crypt = (T) create.Invoke(null, null)) {
byte[] hashBytes = crypt.ComputeHash(stream);
foreach (byte bt in hashBytes) {
sb.Append(bt.ToString("x2"));
}
}
return sb.ToString();
}
Probably not the best way, but it can be handy.
Okay, now the boss has burst in again - I want a list of all of our cars with the brand and a total of how many of that brand we have!
This is a great opportunity to use the next trick in our bag of SQL goodies - the subquery. If you are unfamiliar with the term, a subquery is a query that runs inside another query. There are many different ways to use them.
For our request, lets first put a simple query together that will list each car and the brand:
select
a.ID,
b.brand
from
cars a
join brands b
on a.brand=b.ID
Now, if we wanted to simply get a count of cars sorted by brand, we could of course write this:
select
b.brand,
count(a.ID) as countCars
from
cars a
join brands b
on a.brand=b.ID
group by
b.brand
+--------+-----------+
| brand | countCars |
+--------+-----------+
| BMW | 2 |
| Ford | 2 |
| Nissan | 1 |
| Smart | 1 |
| Toyota | 5 |
+--------+-----------+
So, we should be able to simply add in the count function to our original query right?
select
a.ID,
b.brand,
count(a.ID) as countCars
from
cars a
join brands b
on a.brand=b.ID
group by
a.ID,
b.brand
+----+--------+-----------+
| ID | brand | countCars |
+----+--------+-----------+
| 1 | Toyota | 1 |
| 2 | Ford | 1 |
| 3 | Nissan | 1 |
| 4 | Smart | 1 |
| 5 | Toyota | 1 |
| 6 | BMW | 1 |
| 7 | Ford | 1 |
| 8 | Toyota | 1 |
| 9 | Toyota | 1 |
| 10 | BMW | 1 |
| 11 | Toyota | 1 |
+----+--------+-----------+
11 rows in set (0.00 sec)
Sadly, no, we can't do that. The reason is that when we add in the car ID (column a.ID) we have to add it into the group by - so now, when the count function works, there is only one ID matched per ID.
This is where we can however use a subquery - in fact we can do two completely different types of subquery that will return the same results that we need for this. The first is to simply put the subquery in the select
clause. This means each time we get a row of data, the subquery will run off, get a column of data and then pop it into our row of data.
select
a.ID,
b.brand,
(
select
count(c.ID)
from
cars c
where
a.brand=c.brand
) as countCars
from
cars a
join brands b
on a.brand=b.ID
+----+--------+-----------+
| ID | brand | countCars |
+----+--------+-----------+
| 2 | Ford | 2 |
| 7 | Ford | 2 |
| 1 | Toyota | 5 |
| 5 | Toyota | 5 |
| 8 | Toyota | 5 |
| 9 | Toyota | 5 |
| 11 | Toyota | 5 |
| 3 | Nissan | 1 |
| 4 | Smart | 1 |
| 6 | BMW | 2 |
| 10 | BMW | 2 |
+----+--------+-----------+
11 rows in set (0.00 sec)
And Bam!, this would do us. If you noticed though, this sub query will have to run for each and every single row of data we return. Even in this little example, we only have five different Brands of car, but the subquery ran eleven times as we have eleven rows of data that we are returning. So, in this case, it doesn't seem like the most efficient way to write code.
For a different approach, lets run a subquery and pretend it is a table:
select
a.ID,
b.brand,
d.countCars
from
cars a
join brands b
on a.brand=b.ID
join
(
select
c.brand,
count(c.ID) as countCars
from
cars c
group by
c.brand
) d
on a.brand=d.brand
+----+--------+-----------+
| ID | brand | countCars |
+----+--------+-----------+
| 1 | Toyota | 5 |
| 2 | Ford | 2 |
| 3 | Nissan | 1 |
| 4 | Smart | 1 |
| 5 | Toyota | 5 |
| 6 | BMW | 2 |
| 7 | Ford | 2 |
| 8 | Toyota | 5 |
| 9 | Toyota | 5 |
| 10 | BMW | 2 |
| 11 | Toyota | 5 |
+----+--------+-----------+
11 rows in set (0.00 sec)
Okay, so we have the same results (ordered slightly different - it seems the database wanted to return results ordered by the first column we picked this time) - but the same right numbers.
So, what's the difference between the two - and when should we use each type of subquery? First, lets make sure we understand how that second query works. We selected two tables in the from
clause of our query, and then wrote a query and told the database that it was in fact a table instead - which the database is perfectly happy with. There can be some benefits to using this method (as well as some limitations). Foremost is that this subquery ran once. If our database contained a large volume of data, there could well be a massive improvement over the first method. However, as we are using this as a table, we have to bring in extra rows of data - so that they can actually be joined back to our rows of data. We also have to be sure that there are enough rows of data if we are going to use a simple join like in the query above. If you recall, the join will only pull back rows that have matching data on both sides of the join. If we aren't careful, this could result in valid data not being returned from our cars table if there wasn't a matching row in this subquery.
Now, looking back at the first subquery, there are some limitations as well. because we are pulling data back into a single row, we can ONLY pull back one row of data. Subqueries used in the select
clause of a query very often use only an aggregate function such as sum
, count
, max
or another similar aggregate function. They don't have to, but that is often how they are written.
So, before we move on, lets have a quick look at where else we can use a subquery. We can use it in the where
clause - now, this example is a little contrived as in our database, there are better ways of getting the following data, but seeing as it is only for an example, lets have a look:
select
ID,
brand
from
brands
where
brand like '%o%'
+----+--------+
| ID | brand |
+----+--------+
| 1 | Ford |
| 2 | Toyota |
| 6 | Holden |
+----+--------+
3 rows in set (0.00 sec)
This returns us a list of brand IDs and Brand names (the second column is only added to show us the brands) that contain the letter o
in the name.
Now, we could use the results of this query in a where clause this:
select
a.ID,
b.brand
from
cars a
join brands b
on a.brand=b.ID
where
a.brand in
(
select
ID
from
brands
where
brand like '%o%'
)
+----+--------+
| ID | brand |
+----+--------+
| 2 | Ford |
| 7 | Ford |
| 1 | Toyota |
| 5 | Toyota |
| 8 | Toyota |
| 9 | Toyota |
| 11 | Toyota |
+----+--------+
7 rows in set (0.00 sec)
As you can see, even though the subquery was returning the three brand IDs, our cars table only had entries for two of them.
In this case, for further detail, the subquery is working as if we wrote the following code:
select
a.ID,
b.brand
from
cars a
join brands b
on a.brand=b.ID
where
a.brand in (1,2,6)
+----+--------+
| ID | brand |
+----+--------+
| 1 | Toyota |
| 2 | Ford |
| 5 | Toyota |
| 7 | Ford |
| 8 | Toyota |
| 9 | Toyota |
| 11 | Toyota |
+----+--------+
7 rows in set (0.00 sec)
Again, you can see how a subquery vs manual inputs has changed the order of the rows when returning from the database.
While we are discussing subqueries, lets see what else we can do with a subquery:
select
clause, some in the from
clause and a couple more in the where
clause - just remember that each one you put in is making your query more complex and likely to take longer to execute.If you need to write some efficient code, it can be beneficial to write the query a number of ways and see (either by timing it or by using an explain plan) which is the optimal query to get your results. The first way that works may not always be the best way of doing it.
If you're working with massive data, a memoized approach would be best:
# First create a dictionary of manually stored values
color_dict = {'Z':'red'}
# Second, build a dictionary of "other" values
color_dict_other = {x:'green' for x in df['Set'].unique() if x not in color_dict.keys()}
# Next, merge the two
color_dict.update(color_dict_other)
# Finally, map it to your column
df['color'] = df['Set'].map(color_dict)
This approach will be fastest when you have many repeated values. My general rule of thumb is to memoize when: data_size
> 10**4
& n_distinct
< data_size/4
E.x. Memoize in a case 10,000 rows with 2,500 or fewer distinct values.
If you mean like a text in the background, I'd say you use a label with the input field and position it on the input using CSS, of course. With JS, you fade out the label when the input receives values and fade it in when the input is empty. In this way, it is not possible for the user to submit the description, whether by accident or intent.
I had a problem with a big delay between calling setNeedsDisplay and drawRect: (5 seconds). It turned out I called setNeedsDisplay in a different thread than the main thread. After moving this call to the main thread the delay went away.
Hope this is of some help.

You can safely remove from a set during iteration with an Iterator object; attempting to modify a set through its API while iterating will break the iterator. the Set class provides an iterator through getIterator().
however, Integer objects are immutable; my strategy would be to iterate through the set and for each Integer i, add i+1 to some new temporary set. When you are finished iterating, remove all the elements from the original set and add all the elements of the new temporary set.
Set<Integer> s; //contains your Integers
...
Set<Integer> temp = new Set<Integer>();
for(Integer i : s)
temp.add(i+1);
s.clear();
s.addAll(temp);
I had the same error, but I had it fixed by modifying the php.ini
file.
Find your php.ini file see Dude, where's my php.ini?
then open it with your favorite editor.
Look for a short_open_tag
property, and apply the following change:
; short_open_tag = Off ; previous value
short_open_tag = On ; new value
The following code creates an anonymous struct with the alias myStruct
:
typedef struct{
int one;
int two;
} myStruct;
You can't refer it without the alias because you don't specify an identifier for the structure.
Descending Sort by date
It will help to filter records with date in descending order.
$scope.logData = [
{ event: 'Payment', created_at: '04/05/17 6:47 PM PST' },

];

Probably the best solution is to look at the threeparttable/threeparttablex packages.
Use ternary operator:
echo (($test == '') ? $redText : '');
echo $test == '' ? $redText : ''; //removed parenthesis
But in this case you can't use shorter reversed version because it will return bool(true)
in first condition.
echo (($test != '') ?: $redText); //this will not work properly for this case
If none of them are working then check this.. say if you have x and y arrays of data along respective axis. Then check in which cell(jupyter) you have initialized x and y to empty. This is because , maybe you are appending data to x and y without re-initializing them. So plot has old data too. So check that..
The logical OR '||' automatically short circuits if it meets a true condition once.
false || false || true || false = true, stops at second condition.
On the other hand, the logical AND '&&' automatically short circuits if it meets a false condition once.
false && true && true && true = false, stops at first condition.
I would suggest static class with static readonly. Please find the code snippet below:
public static class CachedKeysManager
{
public static readonly string DistributorList = "distributorList";
}
That’s because j+3
doesn’t change the value of j
. You need to replace that with j = j + 3
or j += 3
so that the value of j
is increased by 3:
for (j = 0; j <= 90; j += 3) { }
I've never actually used this, but try view.getClass().getGenericSuperclass()
Another option would be file_get_contents()
:
// $xml_str = your xml
// $url = target url
$post_data = array('xml' => $xml_str);
$stream_options = array(
'http' => array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded' . "\r\n",
'content' => http_build_query($post_data)));
$context = stream_context_create($stream_options);
$response = file_get_contents($url, null, $context);
The way I would do it is to create paragraph tags where you want your error messages with the same class and show them when the data is invalid. Here is my fiddle
if ($('#email').val() == '' || !$('#password').val() == '') {
$('.loginError').show();
return false;
}

Instead of a lengthy replace, try this one:
public static function slugify($text)
{
// replace non letter or digits by -
$text = preg_replace('~[^\pL\d]+~u', '-', $text);
// transliterate
$text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
// remove unwanted characters
$text = preg_replace('~[^-\w]+~', '', $text);
// trim
$text = trim($text, '-');
// remove duplicate -
$text = preg_replace('~-+~', '-', $text);
// lowercase
$text = strtolower($text);
if (empty($text)) {
return 'n-a';
}
return $text;
}
This was based off the one in Symfony's Jobeet tutorial.
In Python 2.x, just use the ord
and chr
functions:
>>> ord('c')
99
>>> ord('c') + 1
100
>>> chr(ord('c') + 1)
'd'
>>>
Python 3.x makes this more organized and interesting, due to its clear distinction between bytes and unicode. By default, a "string" is unicode, so the above works (ord
receives Unicode chars and chr
produces them).
But if you're interested in bytes (such as for processing some binary data stream), things are even simpler:
>>> bstr = bytes('abc', 'utf-8')
>>> bstr
b'abc'
>>> bstr[0]
97
>>> bytes([97, 98, 99])
b'abc'
>>> bytes([bstr[0] + 1, 98, 99])
b'bbc'
Use PHP Document Object Model:
<?php
$str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
$DOM = new DOMDocument;
$DOM->loadHTML($str);
//get all H1
$items = $DOM->getElementsByTagName('h1');
//display all H1 text
for ($i = 0; $i < $items->length; $i++)
echo $items->item($i)->nodeValue . "<br/>";
?>
This outputs as:
T1
T2
T3
[EDIT]: After OP Clarification:
If you want the content like Lorem ipsum. etc, you can directly use this regex:
<?php
$str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
echo preg_replace("#<h1.*?>.*?</h1>#", "", $str);
?>
this outputs:
Lorem ipsum.The quick red fox...... jumps over the lazy brown FROG

OpenJDK is a reference model and open source, while Oracle JDK is an implementation of the OpenJDK and is not open source. Oracle JDK is more stable than OpenJDK.
OpenJDK is released under GPL v2 license whereas Oracle JDK is licensed under Oracle Binary Code License Agreement.
OpenJDK and Oracle JDK have almost the same code, but Oracle JDK has more classes and some bugs fixed.
So if you want to develop enterprise/commercial software I would suggest to go for Oracle JDK, as it is thoroughly tested and stable.
I have faced lot of problems with application crashes using OpenJDK, which are fixed just by switching to Oracle JDK
You need to assign display: block;
property to the wrapping anchor. Otherwise it won't wrap correctly.
<a style="display:block" href="http://justinbieber.com">

Something like this..
RelativeLayout linearLayout = (RelativeLayout) findViewById(R.id.widget43);
// ListView listView = (ListView) findViewById(R.id.ListView01);
LayoutInflater inflater = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// View footer = inflater.inflate(R.layout.footer, null);
View footer = LayoutInflater.from(this).inflate(R.layout.footer,
null);
final RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 1);
footer.setLayoutParams(layoutParams);
another simple approach with modern built-in stuff like PercentRelativeLayout is now available for new users who hit this problem. thanks to android team for release this item.
<android.support.percent.PercentRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
app:layout_widthPercent="50%">
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/picture"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop" />
<TextView
android:id="@+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#55000000"
android:paddingBottom="15dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="15dp"
android:textColor="@android:color/white" />
</FrameLayout>
and for better performance you can use some stuff like picasso image loader which help you to fill whole width of every image parents. for example in your adapter you should use this:
int width= context.getResources().getDisplayMetrics().widthPixels;
com.squareup.picasso.Picasso
.with(context)
.load("some url")
.centerCrop().resize(width/2,width/2)
.error(R.drawable.placeholder)
.placeholder(R.drawable.placeholder)
.into(item.drawableId);
now you dont need CustomImageView Class anymore.
P.S i recommend to use ImageView in place of Type Int in class Item.
hope this help..
I had the same problem and I solved it with get_object_vars mentioned above.
Furthermore, I had to convert my object with json_decode and I had to iterate the array with the oldschool "for" loop (rather then for-each).
Or this really short version, returns true if the browsers is Internet Explorer:
function isIe() {
return window.navigator.userAgent.indexOf("MSIE ") > 0
|| !!navigator.userAgent.match(/Trident.*rv\:11\./);
}
To download a file please use the following code ... Store the File name with location in $file variable. It supports all mime type
$file = "location of file to download"
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
To know about Mime types please refer to this link: http://php.net/manual/en/function.mime-content-type.php
you certainly won't succeed with
tail -f /var/log/foo.log |grep --line-buffered string2search
when you use "colortail" as an alias for tail, eg. in bash
alias tail='colortail -n 30'
you can check by
type alias
if this outputs something like
tail isan alias of colortail -n 30
.
then you have your culprit :)
Solution:
remove the alias with
unalias tail
ensure that you're using the 'real' tail binary by this command
type tail
which should output something like:
tail is /usr/bin/tail
and then you can run your command
tail -f foo.log |grep --line-buffered something
Good luck.
just set position: fixed
to the footer element (instead of relative)
Note that you may need to also set a margin-bottom
to the main
element at least equal to the height of the footer element (e.g. margin-bottom: 1.5em;
) otherwise, in some circustances, the bottom area of the main content could be partially overlapped by your footer
A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.
The Runnable Interface requires of the class to implement the method run()
like so:
public class MyRunnableTask implements Runnable {
public void run() {
// do stuff here
}
}
And then use it like this:
Thread t = new Thread(new MyRunnableTask());
t.start();
If you did not have the Runnable
interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run()
method in your class, so you could get errors. That is why you need to implement the interface.
Note that you do not need to define a class as usual, you can do all of that inline:
Thread t = new Thread(new Runnable() {
public void run() {
// stuff here
}
});
t.start();
This is similar to the above, only you don't create another named class.
If you want to find the rows that are duplicated you can use find_duplicates
from hablar
:
library(dplyr)
library(hablar)
df <- tibble(a = c(1, 2, 2, 4),
b = c(5, 2, 2, 8))
df %>% find_duplicates()
Important to point out, as others have, MySQL or MariaDB use a different syntax. Also it supports a very convenient USING syntax (in contrast to T/SQL). Also INNER JOIN is synonymous with JOIN. Therefor the query in the original question would be best implemented in MySQL thusly:
UPDATE
Some_Table AS Table_A
JOIN
Other_Table AS Table_B USING(id)
SET
Table_A.col1 = Table_B.col1,
Table_A.col2 = Table_B.col2
WHERE
Table_A.col3 = 'cool'
I've not seen the a solution to the asked question in the other answers, hence my two cents. (tested on PHP 7.4.0 MariaDB 10.4.10)
They are slightly different - the ETag does not have any information that the client can use to determine whether or not to make a request for that file again in the future. If ETag is all it has, it will always have to make a request. However, when the server reads the ETag from the client request, the server can then determine whether to send the file (HTTP 200) or tell the client to just use their local copy (HTTP 304). An ETag is basically just a checksum for a file that semantically changes when the content of the file changes.
The Expires header is used by the client (and proxies/caches) to determine whether or not it even needs to make a request to the server at all. The closer you are to the Expires date, the more likely it is the client (or proxy) will make an HTTP request for that file from the server.
So really what you want to do is use BOTH headers - set the Expires header to a reasonable value based on how often the content changes. Then configure ETags to be sent so that when clients DO send a request to the server, it can more easily determine whether or not to send the file back.
One last note about ETag - if you are using a load-balanced server setup with multiple machines running Apache you will probably want to turn off ETag generation. This is because inodes are used as part of the ETag hash algorithm which will be different between the servers. You can configure Apache to not use inodes as part of the calculation but then you'd want to make sure the timestamps on the files are exactly the same, to ensure the same ETag gets generated for all servers.
I had this issue when running ng test
, so to fix it, I added to my xyz.component.spec.ts
file:
import { MatTableModule } from '@angular/material';
And added it to imports
section in TestBed.configureTestingModule({})
:
beforeEach(async(() => {
TestBed.configureTestingModule({
imports: [ ReactiveFormsModule, HttpClientModule, RouterTestingModule, MatTableModule ],
declarations: [ BookComponent ],
schemas: [ CUSTOM_ELEMENTS_SCHEMA ]
})
.compileComponents();
}));
If your string constraint is not just one string you can drop those corresponding rows with:
df = df[~df['your column'].isin(['list of strings'])]
The above will drop all rows containing elements of your list
Try this:
valgrind --leak-check=full -v ./your_program
As long as valgrind is installed it will go through your program and tell you what's wrong. It can give you pointers and approximate places where your leaks may be found. If you're segfault'ing, try running it through gdb
.
Yeap, you just need to make .
match newline :
$string =~ /(START)(.+?)(END)/s;
In many cases recursion is faster because of caching, which improves performance. For example, here is an iterative version of merge sort using the traditional merge routine. It will run slower than the recursive implementation because of caching improved performances.
public static void sort(Comparable[] a)
{
int N = a.length;
aux = new Comparable[N];
for (int sz = 1; sz < N; sz = sz+sz)
for (int lo = 0; lo < N-sz; lo += sz+sz)
merge(a, lo, lo+sz-1, Math.min(lo+sz+sz-1, N-1));
}
private static void sort(Comparable[] a, Comparable[] aux, int lo, int hi)
{
if (hi <= lo) return;
int mid = lo + (hi - lo) / 2;
sort(a, aux, lo, mid);
sort(a, aux, mid+1, hi);
merge(a, aux, lo, mid, hi);
}
PS - this is what was told by Professor Kevin Wayne (Princeton University) on the course on algorithms presented on Coursera.
Try do something like this (the problem was that you trying to use MyBook.Worksheets
, but MyBook
is not a Workbook
object, but string
, containing workbook name. I've added new varible Set WB = ActiveWorkbook
, so you can use WB.Worksheets
instead MyBook.Worksheets
):
Sub NewWBandPasteSpecialALLSheets()
MyBook = ActiveWorkbook.Name ' Get name of this book
Workbooks.Add ' Open a new workbook
NewBook = ActiveWorkbook.Name ' Save name of new book
Workbooks(MyBook).Activate ' Back to original book
Set WB = ActiveWorkbook
Dim SH As Worksheet
For Each SH In WB.Worksheets
SH.Range("WholePrintArea").Copy
Workbooks(NewBook).Activate
With SH.Range("A1")
.PasteSpecial (xlPasteColumnWidths)
.PasteSpecial (xlFormats)
.PasteSpecial (xlValues)
End With
Next
End Sub
But your code doesn't do what you want: it doesen't copy something to a new WB. So, the code below do it for you:
Sub NewWBandPasteSpecialALLSheets()
Dim wb As Workbook
Dim wbNew As Workbook
Dim sh As Worksheet
Dim shNew As Worksheet
Set wb = ThisWorkbook
Workbooks.Add ' Open a new workbook
Set wbNew = ActiveWorkbook
On Error Resume Next
For Each sh In wb.Worksheets
sh.Range("WholePrintArea").Copy
'add new sheet into new workbook with the same name
With wbNew.Worksheets
Set shNew = Nothing
Set shNew = .Item(sh.Name)
If shNew Is Nothing Then
.Add After:=.Item(.Count)
.Item(.Count).Name = sh.Name
Set shNew = .Item(.Count)
End If
End With
With shNew.Range("A1")
.PasteSpecial (xlPasteColumnWidths)
.PasteSpecial (xlFormats)
.PasteSpecial (xlValues)
End With
Next
End Sub
Since you don't really need the total number, and in fact want to perform an action after a certain number (in your case 5000), you can use java.nio.file.Files.newDirectoryStream
. The benefit is that you can exit early instead having to go through the entire directory just to get a count.
public boolean isOverMax(){
Path dir = Paths.get("C:/foo/bar");
int i = 1;
try (DirectoryStream<Path> stream = Files.newDirectoryStream(dir)) {
for (Path p : stream) {
//larger than max files, exit
if (++i > MAX_FILES) {
return true;
}
}
} catch (IOException ex) {
ex.printStackTrace();
}
return false;
}
The interface doc for DirectoryStream
also has some good examples.
On CentOS Linux, Python3.6, I edited this file (make a backup copy first)
/usr/lib/python3.6/site-packages/certifi/cacert.pem

naturalWidth and naturalHeight
var img = document.createElement("img");
img.onload = function (event)

console.log("natural:", img.naturalWidth, img.naturalHeight);
console.log("width,height:", img.width, img.height);
console.log("offsetW,offsetH:", img.offsetWidth, img.offsetHeight);
}
img.src = "image.jpg";
document.body.appendChild(img);
// css for tests

Google Guava 14 includes a new class ClassPath
with three methods to scan for top level classes:
getTopLevelClasses()
getTopLevelClasses(String packageName)
getTopLevelClassesRecursive(String packageName)
See the ClassPath
javadocs for more info.
@tableName
Table variables are alive for duration of the script running only i.e. they are only session level objects.
To test this, open two query editor windows under sql server management studio, and create table variables with same name but different structures. You will get an idea. The @tableName
object is thus temporary and used for our internal processing of data, and it doesn't contribute to the actual database structure.
There is another type of table object which can be created for temporary use. They are #tableName
objects declared like similar create statement for physical tables:
Create table #test (Id int, Name varchar(50))
This table object is created and stored in temp database. Unlike the first one, this object is more useful, can store large data and takes part in transactions etc. These tables are alive till the connection is open. You have to drop the created object by following script before re-creating it.
IF OBJECT_ID('tempdb..#test') IS NOT NULL
DROP TABLE #test
Hope this makes sense !
WhatsApp has chosen Erlang a language built for writing scalable applications that are designed to withstand errors. Erlang uses an abstraction called the Actor model for it's concurrency - http://en.wikipedia.org/wiki/Actor_(programming_language) Instead of the more traditional shared memory approach, actors communicate by sending each other messages. Actors unlike threads are designed to be lightweight. Actors could be on the same machine or on different machines and the message passing abstractions works for both. A simple implementation of WhatsApp could be: Each user/device is represented as an actor. This actor is responsible for handling the inbox of the user, how it gets serialized to disk, the messages that the user sends and the messages that the user receives. Let's assume that Alice and Bob are friends on WhatsApp. So there is an an Alice actor and a Bob actor.
Let's trace a series of messages flowing back and forth:
Alice decides to message Bob. Alice's phone establishes a connection to the WhatsApp server and it is established that this connection is definitely from Alice's phone. Alice now sends via TCP the following message: "For Bob: A giant monster is attacking the Golden Gate Bridge". One of the WhatsApp front end server deserializes this message and delivers this message to the actor called Alice.
Alice the actor decides to serialize this and store it in a file called "Alice's Sent Messages", stored on a replicated file system to prevent data loss due to unpredictable monster rampage. Alice the actor then decides to forward this message to Bob the actor by passing it a message "Msg1 from Alice: A giant monster is attacking the Golden Gate Bridge". Alice the actor can retry with exponential back-off till Bob the actor acknowledges receiving the message.
Bob the actor eventually receives the message from (2) and decides to store this message in a file called "Bob's Inbox". Once it has stored this message durably Bob the actor will acknowledge receiving the message by sending Alice the actor a message of it's own saying "I received Msg1". Alice the actor can now stop it's retry efforts. Bob the actor then checks to see if Bob's phone has an active connection to the server. It does and so Bob the actor streams this message to the device via TCP.
Bob sees this message and replies with "For Alice: Let's create giant robots to fight them". This is now received by Bob the actor as outlined in Step 1. Bob the actor then repeats Step 2 and 3 to make sure Alice eventually receives the idea that will save mankind.
WhatsApp actually uses the XMPP protocol instead of the vastly superior protocol that I outlined above, but you get the point.
If you don't mind using 3rd Party Libraries cyclops-react has an extended Stream type that will allow you to do just that via the append / prepend operators.
Individual values, arrays, iterables, Streams or reactive-streams Publishers can be appended and prepended as instance methods.
Stream stream = ReactiveSeq.of(1,2)
.filter(x -> x!=0)
.append(ReactiveSeq.of(3,4))
.filter(x -> x!=1)
.append(5)
.filter(x -> x!=2);
[Disclosure I am the lead developer of cyclops-react]
If you are not using redux-form and you are using local state for changes then your react-select component might look like this:
class MySelect extends Component {
constructor() {
super()
}
state = {
selectedValue: 'default' // your default value goes here
}
render() {
<Select
...
value={this.state.selectedValue}
...
/>
)}
I use regexp:
str = 'Write a program that extracts from a given text all palindromes, e.g. "ABBA", "lamal", "exe".';
var strNew = str.match(/\w+/g);
// Output: ["Write", "a", "program", "that", "extracts", "from", "a", "given", "text", "all", "palindromes", "e", "g", "ABBA", "lamal", "exe"]
You should never use * + !important
. What if you want to change font in some parts your HTML document? You should always use body without important. Use !important
only if there is no other option.
In .NET Framework 4 and later, the Stream
class has a built-in CopyTo
method that you can use.
For earlier versions of the framework, the handy helper function to have is:
public static void CopyStream(Stream input, Stream output)
{
byte[] b = new byte[32768];
int r;
while ((r = input.Read(b, 0, b.Length)) > 0)
output.Write(b, 0, r);
}
Then use one of the above methods to copy to a MemoryStream
and call GetBuffer
on it:
var file = new FileStream("c:\\foo.txt", FileMode.Open);
var mem = new MemoryStream();
// If using .NET 4 or later:
file.CopyTo(mem);
// Otherwise:
CopyStream(file, mem);
// getting the internal buffer (no additional copying)
byte[] buffer = mem.GetBuffer();
long length = mem.Length; // the actual length of the data
// (the array may be longer)
// if you need the array to be exactly as long as the data
byte[] truncated = mem.ToArray(); // makes another copy
Edit: originally I suggested using Jason's answer for a Stream
that supports the Length
property. But it had a flaw because it assumed that the Stream
would return all its contents in a single Read
, which is not necessarily true (not for a Socket
, for example.) I don't know if there is an example of a Stream
implementation in the BCL that does support Length
but might return the data in shorter chunks than you request, but as anyone can inherit Stream
this could easily be the case.
It's probably simpler for most cases to use the above general solution, but supposing you did want to read directly into an array that is bigEnough
:
byte[] b = new byte[bigEnough];
int r, offset;
while ((r = input.Read(b, offset, b.Length - offset)) > 0)
offset += r;
That is, repeatedly call Read
and move the position you will be storing the data at.
After 27 years, I too, am uncomfortable developing in an IDE. I tried these suggestions (above) - and probably just didn't follow everything right -- so I did a web-search and found what worked for me at 'http://incise.org/android-development-on-the-command-line.html'.
The answer seemed to be a combination of all the answers above (please tell me if I'm wrong and accept my apologies if so).
As mentioned above, eclipse/adt does not create the necessary ant files. In order to compile without eclipse IDE (and without creating ant scripts):
1) Generate build.xml in your top level directory:
android list targets (to get target id used below)
android update project --target target_id --name project_name --path top_level_directory
** my sample project had a target_id of 1 and a project name of 't1', and
I am building from the top level directory of project
my command line looks like android update project --target 1 --name t1 --path `pwd`
2) Next I compile the project. I was a little confused by the request to not use 'ant'. Hopefully -- requester meant that he didn't want to write any ant scripts. I say this because the next step is to compile the application using ant
ant target
this confused me a little bit, because i thought they were talking about the
android device, but they're not. It's the mode (debug/release)
my command line looks like ant debug
3) To install the apk onto the device I had to use ant again:
ant target install
** my command line looked like ant debug install
4) To run the project on my android phone I use adb.
adb shell 'am start -n your.project.name/.activity'
** Again there was some confusion as to what exactly I had to use for project
My command line looked like adb shell 'am start -n com.example.t1/.MainActivity'
I also found that if you type 'adb shell' you get put to a cli shell interface
where you can do just about anything from there.
3A) A side note: To view the log from device use:
adb logcat
3B) A second side note: The link mentioned above also includes instructions for building the entire project from the command.
Hopefully, this will help with the question. I know I was really happy to find anything about this topic here.
Attributes to Object conversion
*Requires: lodash
function getAttributes(element, parseJson=false){
let results = {}
for (let i = 0, n = element.attributes.length; i < n; i++){
let key = element.attributes[i].nodeName.replace('-', '.')
let value = element.attributes[i].nodeValue
if(parseJson){
try{
if(_.isString(value))
value = JSON.parse(value)
} catch(e) {}
}
_.set(results, key, value)
}
return results
}
This will convert all html attributes to a nested object
Example HTML: <div custom-nested-path1="value1" custom-nested-path2="value2"></div>
Result: {custom:{nested:{path1:"value1",path2:"value2"}}}
If parseJson is set to true json values will be converted to objects

header. Make sure when you get the file from the server that the header is present and correct, and that the file hasn't been transcoded by the web server.
You can change the last line to following (assuming you want to return 0 when there is nothing in db):
return OrdersPerHour == null ? 0 : OrdersPerHour.Value;
Here's a function to escape HTML:
function escapeHtml(str)
{
var map =
{
'&': '&',
'<': '<',
'>': '>',
'"': '"',
"'": '''
};
return str.replace(/[&<>"']/g, function(m) {return map[m];});
}
And to decode:
function decodeHtml(str)
{
var map =
{
'&': '&',
'<': '<',
'>': '>',
'"': '"',
''': "'"
};
return str.replace(/&|<|>|"|'/g, function(m) {return map[m];});
}

That has worked for the past 3 versions of Eclipse at least. If there is not such an option on your eclipse, get a fresh installation (for Java EE developers).
When running this command:
ALTER TABLE MYTABLENAME MODIFY CONSTRAINT MYCONSTRAINTNAME_FK ENABLE;
I got this error:
ORA-02270: no matching unique or primary key for this column-list
02270. 00000 - "no matching unique or primary key for this column-list"
*Cause: A REFERENCES clause in a CREATE/ALTER TABLE statement
gives a column-list for which there is no matching unique or primary
key constraint in the referenced table.
*Action: Find the correct column names using the ALL_CONS_COLUMNS
The referenced table has a primary key constraint with matching type. The root cause of this error, in my case, was that the primary key constraint was disabled.
Anonymous FTP usage is covered by RFC 1635: How to Use Anonymous FTP:
What is Anonymous FTP?
Anonymous FTP is a means by which archive sites allow general access to their archives of information. These sites create a special account called "anonymous".
…
Traditionally, this special anonymous user account accepts any string as a password, although it is common to use either the password "guest" or one's electronic mail (e-mail) address. Some archive sites now explicitly ask for the user's e-mail address and will not allow login with the "guest" password. Providing an e-mail address is a courtesy that allows archive site operators to get some idea of who is using their services.
These are general recommendations, though. Each FTP server may have its own guidelines.
For sample use of the ftp
command on anonymous FTP access, see appendix A:

Pretty simple method is to just pass the creds in the url, can be slightly suspect though - use with caution.
import os
def getRepo(repo_url, login_object):
'''
Clones the passed repo to my staging dir
'''
path_append = r"stage\repo" # Can set this as an arg
os.chdir(path_append)
repo_moddedURL = 'https://' + login_object['username'] + ':' + login_object['password'] + '@github.com/UserName/RepoName.git'
os.system('git clone '+ repo_moddedURL)
print('Cloned!')
if __name__ == '__main__':
getRepo('https://github.com/UserName/RepoYouWant.git', {'username': 'userName', 'password': 'passWord'})
You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.
As I mentioned in the comment, having to use the dot()
function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.
Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @
infix-operator for matrix multiplication, thanks to pep 465.
Edit: Regarding your comment:
Yes. The whole of numpy is based on arrays.
Yes. linalg.norm(v)
is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.
To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.
An example in ipython:
In [1]: import math
In [2]: import numpy as np
In [3]: a = np.array([4,2,7])
In [4]: np.linalg.norm(a)
Out[4]: 8.3066238629180749
In [5]: math.sqrt(sum([n**2 for n in a]))
Out[5]: 8.306623862918075
In [6]: b = a/np.linalg.norm(a)
In [7]: np.linalg.norm(b)
Out[7]: 1.0
Note that In [5]
is an alternative way to calculate the length. In [6]
shows normalizing the vector.
You most probably don't need z-index to do that. You can use relative and absolute positioning.
I advise you to take a better look at css positioning and the difference between relative and absolute positioning... I saw you're setting position: absolute;
to an element and trying to float that element. It won't work friend! When you understand positioning in CSS it will make your work a lot easier! ;)
Edit: Just to be clear, positioning is not a replacement for them and I do use z-index
. I just try to avoid using them. Using z-indexes
everywhere seems easy and fun at first... until you have bugs related to them and find yourself having to revisit and manage z-indexes
.
In Pycharm Just use Shift+Tab to move a block of code left.
This will remove the duplicate object without passing any key.
uniqueArray = a => [...new Set(a.map(o => JSON.stringify(o)))].map(s => JSON.parse(s));_x000D_

var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }, { 'x': 1, 'y': 2 }];_x000D_
_x000D_
var unique = uniqueArray(objects);_x000D_
console.log('Original Object',objects);_x000D_
console.log('Unique',unique);

uniqueArray = a => [...new Set(a.map(o => JSON.stringify(o)))].map(s => JSON.parse(s));
var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }, { 'x': 1, 'y': 2 }];
var unique = uniqueArray(objects);
console.log(objects);
console.log(unique);
Example code:
class inside:
def __init__(self):
self.l = []
def insert(self, element):
self.l.append(element)
class outside:
l = [] # static variable - the same for all instances
def insert(self, element):
self.l.append(element)
def main():
x = inside()
x.insert(8)
print(x.l) # [8]
y = inside()
print(y.l) # []
# ----------------------------
x = outside()
x.insert(8)
print(x.l) # [8]
y = outside()
print(y.l) # [8] # here is the difference

Sorry that was a typo. You can either add node_modules to the end of your user's global path variable, or maybe check the permissions associated with that folder (node _modules). The error doesn't seem like the last case, but I've encountered problems similar to yours. I find the first solution enough for most cases. Just go to environment variables and add the path to node_modules to the last part of your user's path variable. Note I'm saying user and not system.
Just add a semicolon to the end of the variable declaration and add the static path to your node_module folder. ( Ex c:\path\to\node_module)
Alternatively you could:
In your CMD
PATH=%PATH%;C:\\path\to\node_module
EDIT
The last solution will work as long as you don't close your CMD. So, use the first solution for a permanent change.
Use the following command on the your command line:
fsutil file createnew filename requiredSize
The parameters info as followed:
fsutil - File system utility ( the executable you are running )
file - triggers a file action
createnew - the action to perform (create a new file)
filename - would be literally the name of the file
requiredSize - would allocate a file size in bytes in the created file
Vue2: if you only want to detect change on input blur (e.g. after press enter or click somewhere else) do (more info here)
<input @change="foo" v-model... >
If you wanna detect single character changes (during user typing) use
<input @keydown="foo" v-model... >
You can also use @keyup
and @input
events. If you wanna to pass additional parameters use in template e.g. @keyDown="foo($event, param1, param2)"

For those coming to this with similar problems, this request library allows you to make external http requests seemlessly within your php application. Simplified GET, POST, PATCH, DELETE and PUT requests.
A sample request would be as below
use Libraries\Request;
$data = [
'samplekey' => 'value',
'otherkey' => 'othervalue'
];
$headers = [
'Content-Type' => 'application/json',
'Content-Length' => sizeof($data)
];
$response = Request::post('https://example.com', $data, $headers);
// the $response variable contains response from the request
Documentation for the same can be found in the project's README.md
If you're using GNU find,
find . -mtime 1 -exec cp -t ~/test/ {} +
This works as well as piping the output into xargs
while avoiding the pitfalls of doing so (it handles embedded spaces and newlines without having to use find ... -print0 | xargs -0 ...
).
The code below will open the link in a new tab.
String selectLinkOpeninNewTab = Keys.chord(Keys.CONTROL,Keys.RETURN);
driver.findElement(By.linkText("urlLink")).sendKeys(selectLinkOpeninNewTab);
The code below will open an empty new tab.
String selectLinkOpeninNewTab = Keys.chord(Keys.CONTROL,"t");
driver.findElement(By.linkText("urlLink")).sendKeys(selectLinkOpeninNewTab);
To disable inputting password:
sudo visudo
Then add a new line like below and save then:
# The user can run installer as root without inputting password
yourusername ALL=(root) NOPASSWD: /usr/sbin/installer
Then you run installer without password:
sudo installer -pkg ...
In Angular UI Bootstrap 0.13.X, tooltip-html-unsafe has been deprecated. You should now use tooltip-html and $sce.trustAsHtml() to accomplish a tooltip with html.

$scope.htmlTooltip = $sce.trustAsHtml('I\'ve been made <b>bold</b>!');

For anyone looking for a Xamarin implementation (since events are done differently in C#), I simply created this NavClickHandler
class as follows:
public class NavClickHandler : Java.Lang.Object, View.IOnClickListener
{
private Activity mActivity;
public NavClickHandler(Activity activity)
{
this.mActivity = activity;
}
public void OnClick(View v)
{
DrawerLayout drawer = (DrawerLayout)mActivity.FindViewById(Resource.Id.drawer_layout);
if (drawer.IsDrawerOpen(GravityCompat.Start))
{
drawer.CloseDrawer(GravityCompat.Start);
}
else
{
drawer.OpenDrawer(GravityCompat.Start);
}
}
}
Then, assigned a custom hamburger menu button like this:
SupportActionBar.SetDisplayHomeAsUpEnabled(true);
SupportActionBar.SetDefaultDisplayHomeAsUpEnabled(false);
this.drawerToggle.DrawerIndicatorEnabled = false;
this.drawerToggle.SetHomeAsUpIndicator(Resource.Drawable.MenuButton);
And finally, assigned the drawer menu toggler a ToolbarNavigationClickListener of the class type I created earlier:
this.drawerToggle.ToolbarNavigationClickListener = new NavClickHandler(this);
And then you've got a custom menu button, with click events handled.
You can log all uncaught exceptions on the main thread by assigning a handler to sys.excepthook
, perhaps using the exc_info
parameter of Python's logging functions:
import sys
import logging
logging.basicConfig(filename='/tmp/foobar.log')
def exception_hook(exc_type, exc_value, exc_traceback):
logging.error(
"Uncaught exception",
exc_info=(exc_type, exc_value, exc_traceback)
)
sys.excepthook = exception_hook
raise Exception('Boom')
If your program uses threads, however, then note that threads created using threading.Thread
will not trigger sys.excepthook
when an uncaught exception occurs inside them, as noted in Issue 1230540 on Python's issue tracker. Some hacks have been suggested there to work around this limitation, like monkey-patching Thread.__init__
to overwrite self.run
with an alternative run
method that wraps the original in a try
block and calls sys.excepthook
from inside the except
block. Alternatively, you could just manually wrap the entry point for each of your threads in try
/except
yourself.
If you right click on any result of "Edit Top 200 Rows" query in SSMS you will see the option "Pane -> SQL". It then shows the SQL Query that was run, which you can edit as you wish.
In SMSS 2012 and 2008, you can use Ctrl+3 to quickly get there.

update based on Ordering by the order of values in a SQL IN() clause
Solution:
DECLARE @counter int
SET @counter = 0
;WITH q AS
(
select * from Products WHERE ID in (SELECT TOP (10) ID FROM Products WHERE ID IN( 3,2,1)
ORDER BY ID DESC)
)
update q set Display= @counter, @counter = @counter + 1
This updates based on descending 3,2,1

if duplicate and ordering items are problem :
[i for i in a if not i in b or b.remove(i)]
a = [1,2,3,3,3,3,4]
b = [1,3]
result: [2, 3, 3, 3, 4]
This is from the Docker documentation itself, might be of help, simple and plain:
"The host directory is, by its nature, host-dependent. For this reason, you can’t mount a host directory from Dockerfile, the VOLUME instruction does not support passing a host-dir, because built images should be portable. A host directory wouldn’t be available on all potential hosts.".

To prevent JUnit from instantiating your test base class just make it
public abstract class MyTestBaseClass { ... whatever... }
(@Ignore reports it as ignored which I reserve for temporarily ignored tests.)
Actually, on Android Studio it is possible. You can have nested resources as shown here :
There is also a plugin to group resources here.
I recommend to avoid this though.
You can now simply get a list of event listeners bound to an object by using the javascript function getEventListeners().
For example type the following in the dev tools console:
// Get all event listners bound to the document object
getEventListeners(document);

@JaredRummler An answer to your comment:
Won't this add an extra new line at the end of the string?
To prevent having a newline added at the end you can use a Boolean value set during the first loop as you will in the code example Boolean firstLine
public static String convertStreamToString(InputStream is) throws IOException {
// http://www.java2s.com/Code/Java/File-Input-Output/ConvertInputStreamtoString.htm
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
Boolean firstLine = true;
while ((line = reader.readLine()) != null) {
if(firstLine){
sb.append(line);
firstLine = false;
} else {
sb.append("\n").append(line);
}
}
reader.close();
return sb.toString();
}
public static String getStringFromFile (String filePath) throws IOException {
File fl = new File(filePath);
FileInputStream fin = new FileInputStream(fl);
String ret = convertStreamToString(fin);
//Make sure you close all streams.
fin.close();
return ret;
}
