I did it! Using <intent-filter>
. Put the following into your manifest file:
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:host="www.youtube.com" android:scheme="http" />
</intent-filter>
This works perfectly!
You just need to append your command after start in the string that you are passing.
String command = "cmd.exe /c start "+"*your command*";
Process child = Runtime.getRuntime().exec(command);
There is a simple solution with splice. According to W3School splice syntax is following;
array.splice(index, howmany, item1, ....., itemX)
index Required. An integer that specifies at what position to add/remove items, Use negative values to specify the position from the end of the array
howmany Required. The number of items to be removed. If set to 0, no items will be removed
item1, ..., itemX Optional. The new item(s) to be added to the array
Keep that in mind, the following js will pop one or more matched item from the given array if found, otherwise wouldn't remove the last item of the array.
var x = [1,2,3,4,5,4,4,6,7];
var item = 4;
var startItemIndex = $.inArray(item, x);
var itemsFound = x.filter(function(elem){
return elem == item;
}).length;
Or
var itemsFound = $.grep(x, function (elem) {
return elem == item;
}).length;
So the final should look like the following
x.splice( startItemIndex , itemsFound );
Hope this helps.

You have to give the values between 0 and 1.0. So divide the RGB values by 255.
myLabel.textColor= [UIColor colorWithRed:(160/255.0) green:(97/255.0) blue:(5/255.0) alpha:1] ;
Update:
You can also use this macro
#define Rgb2UIColor(r, g, b) [UIColor colorWithRed:((r) / 255.0) green:((g) / 255.0) blue:((b) / 255.0) alpha:1.0]
and you can call in any of your class like this
myLabel.textColor = Rgb2UIColor(160, 97, 5);
This is the normal color synax
myLabel.textColor = UIColor(red: (160/255.0), green: (97/255.0), blue: (5/255.0), alpha: 1.0)
//The values should be between 0 to 1
Swift is not much friendly with macros
Complex macros are used in C and Objective-C but have no counterpart in Swift. Complex macros are macros that do not define constants, including parenthesized, function-like macros. You use complex macros in C and Objective-C to avoid type-checking constraints or to avoid retyping large amounts of boilerplate code. However, macros can make debugging and refactoring difficult. In Swift, you can use functions and generics to achieve the same results without any compromises. Therefore, the complex macros that are in C and Objective-C source files are not made available to your Swift code.
So we use extension for this
extension UIColor {
convenience init(_ r: Double,_ g: Double,_ b: Double,_ a: Double) {
self.init(red: r/255, green: g/255, blue: b/255, alpha: a)
}
}
You can use it like
myLabel.textColor = UIColor(160.0, 97.0, 5.0, 1.0)

I had installed android-sdk
using brew
as well as Android Studio. Somehow, having 2 installations was causing this problem. When I uninstalled my brew installation of the sdk using brew cask uninstall android-sdk
and added the following vars to my env. It worked.
export ANDROID_HOME=/Users/<Username>/Library/Android/sdk
export ANDROID_SDK_ROOT=$ANDROID_HOME
OuterClass.this
references the outer class.
You need to use an Angular form directive on the select
. You can do that with ngModel
. For example
@Component({
selector: 'my-app',
template: `
<h2>Select demo</h2>
<select [(ngModel)]="selectedCity" (ngModelChange)="onChange($event)" >
<option *ngFor="let c of cities" [ngValue]="c"> {{c.name}} </option>
</select>
`
})
class App {
cities = [{'name': 'SF'}, {'name': 'NYC'}, {'name': 'Buffalo'}];
selectedCity = this.cities[1];
onChange(city) {
alert(city.name);
}
}
The (ngModelChange)
event listener emits events when the selected value changes. This is where you can hookup your callback.
Note you will need to make sure you have imported the FormsModule
into the application.
Here is a Plunker
It worked for me like this:
Go to Wordpress Admin Dashboard > “Settings” > “Permalinks” > “Common settings”, set the radio button to “Custom Structure” and paste into the text box:
/index.php/%year%/%monthnum%/%day%/%postname%/
and click the Save button.
As of Jackson 1.6, you can use:

or
JsonNode node = mapper.convertValue(object, JsonNode.class);

I believe there are two main reasons for trying to seperate templated code into a header and a cpp:
One is for mere elegance. We all like to write code that is wasy to read, manage and is reusable later.
Other is reduction of compilation times.
I am currently (as always) coding simulation software in conjuction with OpenCL and we like to keep code so it can be run using float (cl_float) or double (cl_double) types as needed depending on HW capability. Right now this is done using a #define REAL at the beginning of the code, but this is not very elegant. Changing desired precision requires recompiling the application. Since there are no real run-time types, we have to live with this for the time being. Luckily OpenCL kernels are compiled runtime, and a simple sizeof(REAL) allows us to alter the kernel code runtime accordingly.
The much bigger problem is that even though the application is modular, when developing auxiliary classes (such as those that pre-calculate simulation constants) also have to be templated. These classes all appear at least once on the top of the class dependency tree, as the final template class Simulation will have an instance of one of these factory classes, meaning that practically every time I make a minor change to the factory class, the entire software has to be rebuilt. This is very annoying, but I cannot seem to find a better solution.

Here is another way to change timezone in datetime format (I know I wasted my energy on this but I didn't see this page so I don't know how) without min. and sec. cause I don't need it for my project:
def change_time_zone(year, month, day, hour):

if hour >= 24:
difference = hour - 24
hour = difference
day += 1
long_months = [1, 3, 5, 7, 8, 10, 12]

elif month in long_months:
if day >= 31:
day = 1
month += 1
if month > 12:
year += 1
elif month == 2:
if not year%4==0:
if day >= 29:
day = 1
month += 1
if month > 12:
year += 1
else:
if day >= 28:

You should use raw_input
to take a string input. then use islower
method of str
object.
s = raw_input('Type a word')
l = []
for c in s.strip():
if c.islower():
print c
l.append(c)
print 'Total number of lowercase letters: %d'%(len(l) + 1)
Just do -
dir(s)
and you will find islower
and other attributes of str
An alternative way would be to create a new temporary table with same structure.
CREATE TABLE temp_table AS SELECT * FROM original_table LIMIT 0
Then create the primary key in the table.
ALTER TABLE temp_table ADD PRIMARY KEY (primary-key-field)
Finally copy all records from the original table while ignoring the duplicate records.
INSERT IGNORE INTO temp_table AS SELECT * FROM original_table
Now you can delete the original table and rename the new table.
DROP TABLE original_table
RENAME TABLE temp_table TO original_table
This solution not only applies to your specific example but is more generally applicable:
const subset2 = (x, y) => ({[x]:a, [y]:b}) => ({[x]:a, [y]:b});_x000D_
_x000D_
const subset3 = (x, y, z) => ({[x]:a, [y]:b, [z]:c}) => ({[x]:a, [y]:b, [z]:c});_x000D_
_x000D_
// const subset4...etc._x000D_
_x000D_
_x000D_
const o = {a:1, b:2, c:3, d:4, e:5};_x000D_
_x000D_
_x000D_
const pickBD = subset2("b", "d");_x000D_
const pickACE = subset3("a", "c", "e");_x000D_
_x000D_
_x000D_
console.log(_x000D_
pickBD(o), // {b:2, d:4}_x000D_
pickACE(o) // {a:1, c:3, e:5}_x000D_
);
_x000D_
You can easily define subset4
etc. to take more properties into account.
var root = document.createElement("div");
root.innerHTML = "My name is <b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";
var texts = [].map.call( root.querySelectorAll("b"), function(v){
return v.textContent || v.innerText || "";
});
//["Bob", "20", "programming"]
It depends what is the character and what encoding it is in:
An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits.
An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte).
A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes).
A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits. This is the encoding used by Windows internally.
A Unicode character in UTF-32 encoding is always 32 bits (4 bytes).
An ASCII character in UTF-8 is 8 bits (1 byte), and in UTF-16 - 16 bits.
The additional (non-ASCII) characters in ISO-8895-1 (0xA0-0xFF) would take 16 bits in UTF-8 and UTF-16.
That would mean that there are between 0.03125 and 0.125 characters in a bit.
String delimiter = ",";
StringBuilder sb = new StringBuilder();
for (Item i : list) {
sb.append(delimiter).append(i);
}
sb.toString().replaceFirst(delimiter, "");
you also need to identify the columns to set dimensions:
foreach (range('A', $phpExcelObject->getActiveSheet()->getHighestDataColumn()) as $col) {
$phpExcelObject
->getActiveSheet()
->getColumnDimension($col)
->setAutoSize(true);
}

I know that due to this ugly anonymous inner class usage of TransactionTemplate
doesn't look nice, but when for some reason we want to have a test method transactional IMHO it is the most flexible option.
In some cases (it depends on the application type) the best way to use transactions in Spring tests is a turned-off @Transactional
on the test methods. Why? Because @Transactional
may leads to many false-positive tests. You may look at this sample article to find out details. In such cases TransactionTemplate
can be perfect for controlling transaction boundries when we want that control.
You can make everything lowercase:
var string="Stackoverflow is the BEST";
var searchstring="best";
var result= (string.toLowerCase()).search((searchstring.toLowerCase()));
alert(result);
Spring sets the default content-type to octet-stream
when the response is missing that field. All you need to do is to add a message converter to fix this.
You can use querySelectorAll to get all span elements and then use new ES2015 (ES6) spread operator convert StaticNodeList that querySelectorAll returns to array of spans, and then use map operator to get list of items.
See example bellow
([...document.querySelectorAll('#test span')]).map(x => console.log(x.innerHTML))
_x000D_
<div id="test">_x000D_
<span>1</span>_x000D_
<span>2</span>_x000D_
<span>3</span>_x000D_
<span>4</span>_x000D_
<div>
_x000D_
A little late but I believe some further clarification is given below.
You can iterate through a JSON array with a simple loop as well, like:
for(var i = 0; i < jsonArray.length; i++)
{
console.log(jsonArray[i].attributename);
}
If you have a JSON object and you want to loop through all of its inner objects, then you first need to get all the keys in an array and loop through the keys to retrieve objects using the key names, like:
var keys = Object.keys(jsonObject);
for(var i = 0; i < keys.length; i++)
{
var key = keys[i];
console.log(jsonObject.key.attributename);
}
Your project is mostly likely targetting .NET Framework 4 Client Profile. Check the application tab in your project properties.
This question has a good answer on the different versions: Target framework, what does ".NET Framework ... Client Profile" mean?
To someone else having nightmare figure out this one. I have a simple solution.
Add timer by using :
-(void)applicationDidEnterBackground {
[self.locationManager stopUpdatingLocation];
UIApplication* app = [UIApplication sharedApplication];
bgTask = [app beginBackgroundTaskWithExpirationHandler:^{
[app endBackgroundTask:bgTask];
bgTask = UIBackgroundTaskInvalid;
}];
self.timer = [NSTimer scheduledTimerWithTimeInterval:intervalBackgroundUpdate
target:self.locationManager
selector:@selector(startUpdatingLocation)
userInfo:nil
repeats:YES];
}
Just don't forget to add "App registers for location updates" in info.plist.
For a new project select the home directory of the jdk
eg C:\Java\jdk1.7.0_99
or C:\Program Files\Java\jdk1.7.0_99
For an existing project.
1) You need to have a jdk
installed on the system.
for instance in
C:\Java\jdk1.7.0_99
2) go to project structure
under File
menu ctrl+alt+shift+S
3) SDKs
is located under Platform Settings
. Select it.
4) click the green +
up the top of the window.
5) select JDK
(I have to use keyboard to select it do not know why).
select the home directory for your jdk installation.
should be good to go.
I would use the RadioButtons in a ListBox, and then bind to the SelectedValue.
This is an older thread about this topic, but the base idea should be the same: http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/323d067a-efef-4c9f-8d99-fecf45522395/
Just add to the CommandArgument
parameter and read it out on the Click
handler:
<asp:LinkButton ID="ENameLinkBtn" runat="server"
style="font-weight: 700; font-size: 8pt;" CommandArgument="YourValueHere"
OnClick="ENameLinkBtn_Click" >
Then in your click event:
protected void ENameLinkBtn_Click(object sender, EventArgs e)
{
LinkButton btn = (LinkButton)(sender);
string yourValue = btn.CommandArgument;
// do what you need here
}
Also you can set the CommandArgument
argument when binding if you are using the LinkButton
in any bindable controls by doing:
CommandArgument='<%# Eval("SomeFieldYouNeedArguementFrom") %>'
If you inherit from Exception, you have to provide a constructor that takes a String as a parameter (it will contain the error message).
Copy-paste the following into your current terminal:
gsettings set org.gnome.desktop.default-applications.terminal exec /usr/bin/terminator
gsettings set org.gnome.desktop.default-applications.terminal exec-arg "-x"
This modifies the dconf to make terminator the default program. You could also use dconf-editor (a GUI-based tool) to make changes to the dconf, as another answer has suggested. If you would like to learn and understand more about this topic, this may help you.
You only need ng-model when you need to access the model's $viewValue or $modelValue. See NgModelController. And in that case, you would use require: '^ngModel'
.
For the rest, see Roys answer.
I'll take the risk of stating the obvious: You call the function, if it's defined in the base class it's automatically available in the derived class (unless it's private
).
If there is a function with the same signature in the derived class you can disambiguate it by adding the base class's name followed by two colons base_class::foo(...)
. You should note that unlike Java and C#, C++ does not have a keyword for "the base class" (super
or base
) since C++ supports multiple inheritance which may lead to ambiguity.
class left {
public:
void foo();
};
class right {
public:
void foo();
};
class bottom : public left, public right {
public:
void foo()
{
//base::foo();// ambiguous
left::foo();
right::foo();
// and when foo() is not called for 'this':
bottom b;
b.left::foo(); // calls b.foo() from 'left'
b.right::foo(); // call b.foo() from 'right'
}
};
Incidentally, you can't derive directly from the same class twice since there will be no way to refer to one of the base classes over the other.
class bottom : public left, public left { // Illegal
};
Java 8 provides the option of using streams which can be used to sort int[] array
as:
int[] sorted = Arrays.stream(array).sorted().toArray(); // option 1
Arrays.parallelSort(array); //option 2
As mentioned in doc for parallelSort
:
The sorting algorithm is a parallel sort-merge that breaks the array into sub-arrays that are themselves sorted and then merged. When the sub-array length reaches a minimum granularity, the sub-array is sorted using the appropriate Arrays.sort method. If the length of the specified array is less than the minimum granularity, then it is sorted using the appropriate Arrays.sort method. The algorithm requires a working space no greater than the size of the original array. The ForkJoin common pool is used to execute any parallel tasks.
So if the input array is less than granularity (8192 elements in Java 9 and 4096 in Java 8 I believe), then parallelSort
simply calls sequential sort algorithm.
Just in case we want to reverse sort the integer array we can make use of comparator as:
int[] reverseSorted = IntStream.of(array).boxed()
.sorted(Comparator.reverseOrder()).mapToInt(i -> i).toArray();
Since Java has no way to sort primitives with custom comparator, we have to use intermediate boxing or some other third party library which implements such primitive sorting.
i had the same problem and was already using the code in the selected answer. this link was the answer for me; maybe for others also.
Be careful of race conditions: if the file disappears between the "exists" check and the time you open it, your program will fail unexpectedly.
It's better to go and open the file, check for failure and if all is good then do something with the file. It's even more important with security-critical code.

My humble construction that
.git
subfolder: low chance to emit a git command in a non-git subfolderfind
as follow:
find . \
-maxdepth 2 -type d \
-name ".git" \
-execdir python -c 'import os; print(os.path.abspath("."))' \; \
-execdir git pull \;
Of course, you may add other git commands with additional -execdir
options to find
, displaying the branch for instance:
find . \
-maxdepth 2 -type d \
-name ".git" \
-execdir python -c 'import os; print(os.path.abspath("."))' \; \
-execdir git branch \;
-execdir git pull \;
I'm not sure what your goal is, but might it be better to use addClass instead? I mean an objects ID in my opinion should be static and specific to that object. If you are just trying to change it from showing on the page or something like that I would put those details in a class and then add it to the object rather then trying to change it's ID. Again, I'm saying that without understand your underlining goal.
Actually, you can achieve this pretty easy. Simply specify the line height as a number:
<p style="line-height:1.5">
<span style="font-size:12pt">The quick brown fox jumps over the lazy dog.</span><br />
<span style="font-size:24pt">The quick brown fox jumps over the lazy dog.</span>
</p>
The difference between number and percentage in the context of the line-height CSS property is that the number value is inherited by the descendant elements, but the percentage value is first computed for the current element using its font size and then this computed value is inherited by the descendant elements.
For more information about the line-height property, which indeed is far more complex than it looks like at first glance, I recommend you take a look at this online presentation.
Edit: Long after I wrote this post and it was accepted as the answer, the am force-stop
command was implemented by the Android team, as mentioned in this answer.
Alternatively: Rather than just stopping the app, since you mention wanting a "clean slate" for each test run, you can use adb shell pm clear com.my.app.package
, which will stop the app process and clear out all the stored data for that app.
If you're on Linux:
adb shell ps | grep com.myapp | awk '{print $2}' | xargs adb shell kill
That will only work for devices/emulators where you have root immediately upon running a shell. That can probably be refined slightly to call su
beforehand.
Otherwise, you can do (manually, or I suppose scripted):
pc $ adb -d shell
android $ su
android # ps
android # kill <process id from ps output>
set the type
of column named dateposted
as DATETIME
and run the following query:
INSERT INTO table (`dateposted`) VALUES (CURRENT_TIMESTAMP)
Here's an approach that combines atomic directory locking with a check for stale lock via PID and restart if stale. Also, this does not rely on any bashisms.
#!/bin/dash
SCRIPTNAME=$(basename $0)
LOCKDIR="/var/lock/${SCRIPTNAME}"
PIDFILE="${LOCKDIR}/pid"
if ! mkdir $LOCKDIR 2>/dev/null
then
# lock failed, but check for stale one by checking if the PID is really existing
PID=$(cat $PIDFILE)
if ! kill -0 $PID 2>/dev/null
then
echo "Removing stale lock of nonexistent PID ${PID}" >&2
rm -rf $LOCKDIR
echo "Restarting myself (${SCRIPTNAME})" >&2
exec "$0" "$@"
fi
echo "$SCRIPTNAME is already running, bailing out" >&2
exit 1
else
# lock successfully acquired, save PID
echo $$ > $PIDFILE
fi
trap "rm -rf ${LOCKDIR}" QUIT INT TERM EXIT
echo hello
sleep 30s
echo bye
Follow these steps to begin using Angular Material.
Step 1: Install Angular Material
npm install --save @angular/material
Step 2: Animations
Some Material components depend on the Angular animations module in order to be able to do more advanced transitions. If you want these animations to work in your app, you have to install the @angular/animations
module and include the BrowserAnimationsModule in your app.
npm install --save @angular/animations
Then
import {BrowserAnimationsModule} from '@angular/platform browser/animations';
@NgModule({
...
imports: [BrowserAnimationsModule],
...
})
export class PizzaPartyAppModule { }
Step 3: Import the component modules
Import the NgModule for each component you want to use:
import {MdButtonModule, MdCheckboxModule} from '@angular/material';
@NgModule({
...
imports: [MdButtonModule, MdCheckboxModule],
...
})
export class PizzaPartyAppModule { }
be sure to import the Angular Material modules after Angular's BrowserModule, as the import order matters for NgModules
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {MdCardModule} from '@angular/material';
@NgModule({
declarations: [
AppComponent,
HeaderComponent,
HomeComponent
],
imports: [
BrowserModule,
FormsModule,
HttpModule,
MdCardModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Step 4: Include a theme
Including a theme is required to apply all of the core and theme styles to your application.
To get started with a prebuilt theme, include the following in your app's index.html:
<link href="../node_modules/@angular/material/prebuilt-themes/indigo-pink.css" rel="stylesheet">
See this MSDN article and an example usage here on Stack Overflow.
Let's say that you have the following Linq/POCO class:
public class Color
{
public int ColorId { get; set; }
public string Name { get; set; }
}
And let's say that you have the following model:
public class PageModel
{
public int MyColorId { get; set; }
}
And, finally, let's say that you have the following list of colors. They could come from a Linq query, from a static list, etc.:
public static IEnumerable<Color> Colors = new List<Color> {
new Color {
ColorId = 1,
Name = "Red"
},
new Color {
ColorId = 2,
Name = "Blue"
}
};
In your view, you can create a drop down list like so:
<%= Html.DropDownListFor(n => n.MyColorId,
new SelectList(Colors, "ColorId", "Name")) %>
For those using git with Jenkins under a windows system, you need to configure the location of git.exe under: Manage Jenkins => Global Tool Configuration => Git => Path to Git executable and fill-in the path to git.exe, for example; C:\Program Files\Git\bin\git.exe
In clausule if, use ()
.
For example:
stringtorray = "xxxx,yyyyy,zzzzz";
if (xxx && (stringtoarray.split(',') + "")) { ...
Display the row as a block.
tr {
display: block;
border-bottom: 1px solid #000;
}
and to display alternate colors simply:
tr.oddrow {
display: block;
border-bottom: 1px solid #F00;

With Log4j2, this can be achieved using the following utility method added to your code.
private static void setLogLevel() {
if (Boolean.getBoolean("log4j.debug")) {
Configurator.setLevel(System.getProperty("log4j.logger"), Level.DEBUG);
}
}
You need these imports
import org.apache.logging.log4j.Level;
import org.apache.logging.log4j.core.config.Configurator;
Now invoke the setLogLevel
method in your main() or whereever appropriate and pass command line params -Dlog4j.logger=com.mypackage.Thingie
and -Dlog4j.debug=true

You can simply use outerHTML property over the element. It will return what you desire.
Let's create a function named get_string(element)
var el = document.createElement("p");
el.appendChild(document.createTextNode("Test"));
function get_string(element) {
console.log(element.outerHTML);
}
get_string(el); // your desired output

If you are using qmake, the standard Qt build system, just add a line to the .pro
file as documented in the qmake Variable Reference:
INCLUDEPATH += <your path>
If you are using your own build system, you create a project by selecting "Import of Makefile-based project". This will create some files in your project directory including a file named <your project name>.includes
. In that file, simply list the paths you want to include, one per line. Really all this does is tell Qt Creator where to look for files to index for auto completion. Your own build system will have to handle the include paths in its own way.
As explained in the Qt Creator Manual, <your path>
must be an absolute path, but you can avoid OS-, host- or user-specific entries in your .pro
file by using $$PWD
which refers to the folder that contains your .pro
file, e.g.
INCLUDEPATH += $$PWD/code/include

With introduction of Java 1.8, streams are very useful in solving this kind of problems:
Comparator <DateTime> myComparator = (arg1, arg2)

if(arg1.lt(arg2))
return -1;
else if (arg1.lteq(arg2))
return 0;
else
return 1;

ArrayList<DateTime> sortedList = myList
.stream()
.sorted(myComparator)
.collect(Collectors.toCollection(ArrayList::new));
.val()
is for input elements, use .html()
instead
The easiest way to add utility functions is to leave them at the global level:
function myUtilityFunction(x) { return "do something with "+x; }
Then, the simplest way to add a utility function (to a controller) is to assign it to $scope
, like this:
$scope.doSomething = myUtilityFunction;
Then you can call it like this:
{{ doSomething(x) }}
or like this:
ng-click="doSomething(x)"
EDIT:
The original question is if the best way to add a utility function is through a service. I say no, if the function is simple enough (like the isNotString()
example provided by the OP).
The benefit of writing a service is to replace it with another (via injection) for the purpose of testing. Taken to an extreme, do you need to inject every single utility function into your controller?
The documentation says to simply define behavior in the controller (like $scope.double
): http://docs.angularjs.org/guide/controller
This can also happen when you're trying to load a DLL and that in turn needs another DLL which cannot be not found.

In general, utf8_general_ci is faster than utf8_unicode_ci, but less correct.
Here is the difference:
For any Unicode character set, operations performed using the _general_ci collation are faster than those for the _unicode_ci collation. For example, comparisons for the utf8_general_ci collation are faster, but slightly less correct, than comparisons for utf8_unicode_ci. The reason for this is that utf8_unicode_ci supports mappings such as expansions; that is, when one character compares as equal to combinations of other characters. For example, in German and some other languages “ß” is equal to “ss”. utf8_unicode_ci also supports contractions and ignorable characters. utf8_general_ci is a legacy collation that does not support expansions, contractions, or ignorable characters. It can make only one-to-one comparisons between characters.
Quoted from: http://dev.mysql.com/doc/refman/5.0/en/charset-unicode-sets.html
For more detailed explanation, please read the following post from MySQL forums: http://forums.mysql.com/read.php?103,187048,188748
As for utf8_bin: Both utf8_general_ci and utf8_unicode_ci perform case-insensitive comparison. In constrast, utf8_bin is case-sensitive (among other differences), because it compares the binary values of the characters.
I'm currently working on such a statement and figured out another fact to notice: INSERT OR REPLACE will replace any values not supplied in the statement. For instance if your table contains a column "lastname" which you didn't supply a value for, INSERT OR REPLACE will nullify the "lastname" if possible (constraints allow it) or fail.
i really disadvise you against using Thread.Sleep(2000)
, because of a several reasons (a few are described here), but most of all because its not useful when it comes to debugging/testing.
I recommend to use a C# Timer instead of Thread.Sleep()
. Timers let you perform methods frequently (if necessary) AND are much easiert to use in testing! There's a very nice example of how to use a timer right behind the hyperlink - just put your logic "what happens after 2 seconds" right into the Timer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
method.
If i
is the int
, then
char c = i;
makes it a char
. You might want to add a check that the value is <128
if it comes from an untrusted source. This is best done with isascii
from <ctype.h>
, if available on your system (see @Steve Jessop's comment to this answer).
For newer Android platforms, one can execute a system utility screencap
in /system/bin
to get the screenshot without root permission.
You can try /system/bin/screencap -h
to see how to use it under adb or any shell.
By the way, I think this method is only good for single snapshot. If we want to capture multiple frames for screen play, it will be too slow. I don't know if there exists any other approach for a faster screen capture.
OK so, it isn't css hack, but out of frustration for not being able to find ways to target ie8 from css, and due to policy of not having ie specific css files, I had to do following, which I assume someone else might find useful:

$(results).css({

'top':'-253px'

I use CDH hadoop and when I export excel report, I have two problems;
1) convert Linux date to excel date,
For that, add an empty column next to date column lets say the top row is B4,
paste below formula and drag the BLACK "+" all the way to your last day at the end of the column. Then hide the original column
=(((B4/1000/60)/60)/24)+DATE(1970|1|1)+(-5/24)
2) Convert disk size from byte to TB, GB, and MB
the best formula for that is this
[>999999999999]# ##0.000,,,," TB";[>999999999]# ##0.000,,," GB";# ##0.000,," MB"
it will give you values with 3 decimals just format cells --> Custom and paste the above code there
You are missing the fact that 6.999,50 is not a valid decimal. You can't have a comma and a decimal point in a decimal value surely? What number is it supposed to be?
Assuming your locale specifies . as grouping and , as decimal separator: To remove the grouping digits:
SELECT CONVERT(decimal(11,2), REPLACE('6.999,50', '.', ''))
will yield 6999,50 as a decimal
for /f "tokens=* delims= " %%f in (myfile) do
This reads a file line-by-line, removing leading spaces (thanks, jeb).
set line=%%f
sets then the line
variable to the line just read and
call :procesToken
calls a subroutine that does something with the line
:processToken
is the start of the subroutine mentioned above.
for /f "tokens=1* delims=/" %%a in ("%line%") do
will then split the line at /
, but stopping tokenization after the first token.
echo Got one token: %%a
will output that first token and
set line=%%b
will set the line
variable to the rest of the line.
if not "%line%" == "" goto :processToken
And if line
isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.
I recommend you use:
var returnedData = JSON.parse(data);
to convert the JSON string (if it is just text) to a JavaScript object.
I just want to clarify something from my own testing.

Of course do your own testing as always.
Should you want to clear the array with something other than a value, std::file wont cut it; instead I found std::generate useful. e.g. I had a vector of lists I wanted to initialize
std::generate(v.begin(), v.end(), [] () { return std::list<X>(); });
You can do ints too e.g.
std::generate(v.begin(), v.end(), [n = 0] () mutable { return n++; });
or just
std::generate(v.begin(), v.end(), [] (){ return 0; });
but I imagine std::fill is faster for the simplest case
Do the following:
grep -rnw '/path/to/somewhere/' -e 'pattern'
-r
or -R
is recursive,-n
is line number, and-w
stands for match the whole word.-l
(lower-case L) can be added to just give the file name of matching files.-e
is the pattern used during the searchAlong with these, --exclude
, --include
, --exclude-dir
flags could be used for efficient searching:
grep --include=\*.{c,h} -rnw '/path/to/somewhere/' -e "pattern"
grep --exclude=\*.o -rnw '/path/to/somewhere/' -e "pattern"
--exclude-dir
parameter. For example, this will exclude the dirs dir1/, dir2/ and all of them matching *.dst/:grep --exclude-dir={dir1,dir2,*.dst} -rnw '/path/to/somewhere/' -e "pattern"
This works very well for me, to achieve almost the same purpose like yours.
For more options check man grep
.
Both functions use the os.path.split(path)
function to split the pathname path
into a pair; (head, tail)
.
The os.path.dirname(path)
function returns the head of the path.
E.g.: The dirname of '/foo/bar/item'
is '/foo/bar'
.
The os.path.basename(path)
function returns the tail of the path.
E.g.: The basename of '/foo/bar/item'
returns 'item'

I'm not sure I understand what you are trying to achieve as we don't have what username()
is supposed to return but you might want to try something like that. I would also recommend you don't echo whole page and rather use something like that, it's much easier to read and maintain:
<?php
require_once ( 'username.php' );
if (isset($_POST)) {
$textfield = $_POST['textfield']; // this will get you what was in the
// textfield if the form was submitted
}
?>
<form name="form1" method="post" action="<?php echo($_SERVER['PHP_SELF']) ?">
<p>Your username is: <?php echo(username()) ?></p>
<p>
<label>
<input type="text" name="textfield" id="textfield">
</label>
</p>
<p>
<label>
<input type="submit" name="button" id="button" value="Submit">
</label>
</p>
</form>
This will post the results in the same page. So first time you display the page, only the empty form is shown, if you press on submit, the textfield field will be in the $textfield
variable and you can display it again as you want.
I don't know if the username()
function was supposed to return you the URL of where you should send the results but that's what you'd want in the action
attribute of your form. I've put the result down in a sample paragraph so you see how you can display the result. See the "Your username is..." part.
// Edit:
If you want to send the value without leaving the page, you want to use AJAX. Do a search on jQuery on StackOverflow or on Google.
You would probably want to have your function return the username instead of echo it though. But if you absolutely want to echo it from the function, just call it like that <?php username() ?>
in your HTML form.
I think you will need to understand the flow of the client-server process of your pages before going further. Let's say that the sample code above is called form.php.
Nothing special. Just as same as common Java Class Instance.
But those class are Synthetic proxy classes
created by java.lang.reflect.Proxy#newProxyInstance
Introduced in 1.3
http://docs.oracle.com/javase/1.3/docs/relnotes/features.html#reflection
It is a part of Java. so each JVM should support it.
In short : they are created using JVM ASM tech ( defining javabyte code at runtime )
something using same tech:
java.lang.reflect.Proxy#newProxyInstance
getProxyClass0
to obtain a `Class
`
ProxyGenerator.generateProxyClass
which return a byte[]define class
to load the generated $Proxy
Class (the classname you have seen)each method is build with same bytecode like
invocation handler
's invoke()
invocation handler
's invoke()
the class(bytecode) represent in form of byte[]
How to draw a class

For anyone else struggling to get to the bottom of this, I tried adjusting timeouts as suggested as I didn't want to stop using Unix sockets...after lots of troubleshooting and not much to go on I found that this issue was being caused by the APC extension that I'd enabled in php-fpm a few months back. Disabling this extension resolved the intermittent 502 errors, easiest way to do this was by commenting out the following line :
;extension = apc.so
This did the trick for me!
Make your activity A in manifest file: launchMode = "singleInstance"
When the user clicks new, do FirstActivity.fa.finish();
and call the new Intent.
When the user clicks modify, call the new Intent or simply finish activity B.
FIRST WAY
In your first activity, declare one Activity object
like this,
public static Activity fa;
onCreate()
{
fa = this;
}
now use that object in another Activity
to finish first-activity like this,
onCreate()
{
FirstActivity.fa.finish();
}
SECOND WAY
While calling your activity FirstActivity
which you want to finish as soon as you move on,
You can add flag while calling FirstActivity
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
But using this flag the activity will get finished evenif you want it not to. and sometime onBack
if you want to show the FirstActivity
you will have to call it using intent.
As @ThierryTemplier said for receiving data from server and also transmitting model between components (to keep intellisense list and make design time error), it's fine to use interface but I think for sending data to server (DTOs) it's better to use class to take advantages of auto mapping DTO from model.
When you check out a tag, you have what's called a "detached head". Normally, Git's HEAD commit is a pointer to the branch that you currently have checked out. However, if you check out something other than a local branch (a tag or a remote branch, for example) you have a "detached head" -- you're not really on any branch. You should not make any commits while on a detached head.
It's okay to check out a tag if you don't want to make any edits. If you're just examining the contents of files, or you want to build your project from a tag, it's okay to git checkout my_tag
and work with the files, as long as you don't make any commits. If you want to start modifying files, you should create a branch based on the tag:
$ git checkout -b my_tag_branch my_tag
will create a new branch called my_tag_branch
starting from my_tag
. It's safe to commit changes on this branch.
Maybe this can help you
Cursor c = db.rawQuery("query",null);
int id[] = new int[c.getCount()];
int i = 0;
if (c.getCount() > 0)

i++;
} while (c.moveToNext());
c.close();
}
I suspect you are running Android 6.0 Marshmallow (API 23) or later. If this is the case, you must implement runtime permissions before you try to read/write external storage.
Adding style="width:100%;max-width:640px"
to the image tag will scale it up to the viewport width, i.e. for larger windows it will look fixed width.
Using http.createServer
is very low-level and really not useful for creating web applications as-is.
A good framework to use on top of it is Express, and I would seriously suggest using it. You can install it using npm install express
.
When you have, you can create a basic application to handle your form:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true }));
//app.use(express.bodyParser());
app.post('/myaction', function(req, res) {
res.send('You sent the name "' + req.body.name + '".');
});
app.listen(8080, function() {
console.log('Server running at http://127.0.0.1:8080/');
});
You can make your form point to it using:
<form action="http://127.0.0.1:8080/myaction" method="post">
The reason you can't run Node on port 80 is because there's already a process running on that port (which is serving your index.html
). You could use Express to also serve static content, like index.html
, using the express.static
middleware.
It can also be solved using the following query along with other answers.

The only way to control the size of stack within process is start a new Thread
. But you can also control by creating a self-calling sub Java process with the -Xss
parameter.

} catch (StackOverflowError e) {
System.err.println("true recursion level was " + level);
System.err.println("reported recursion level was "
+ e.getStackTrace().length);
}
}
};
t.start();
t.join();
try {

System.out.println(fact(1 << 15));
} catch (StackOverflowError e) {
System.err.println("true recursion level was " + level);

You don't need to go to 64-bit to see something like this. Consider int32_t
on common 32-bit platforms. It might be typedef
'ed as int
or as a long
, but obviously only one of the two at a time. int
and long
are of course distinct types.
It's not hard to see that there is no workaround which makes int == int32_t == long
on 32-bit systems. For the same reason, there's no way to make long == int64_t == long long
on 64-bit systems.
If you could, the possible consequences would be rather painful for code that overloaded foo(int)
, foo(long)
and foo(long long)
- suddenly they'd have two definitions for the same overload?!
The correct solution is that your template code usually should not be relying on a precise type, but on the properties of that type. The whole same_type
logic could still be OK for specific cases:
long foo(long x);
std::tr1::disable_if(same_type(int64_t, long), int64_t)::type foo(int64_t);
I.e., the overload foo(int64_t)
is not defined when it's exactly the same as foo(long)
.
[edit] With C++11, we now have a standard way to write this:
long foo(long x);
std::enable_if<!std::is_same<int64_t, long>::value, int64_t>::type foo(int64_t);
[edit] Or C++20
long foo(long x);
int64_t foo(int64_t) requires (!std::is_same_v<int64_t, long>);
Does your script reference /bin/bash
or /bin/sh
in its hash bang line? The default system shell in Ubuntu is dash, not bash, so if you have #!/bin/sh
then your script will be using a different shell than you expect. Dash does not have the <<<
redirection operator.
This works on Laravel 5:
{!!strlen($post->content) > 200 ? substr($post->content,0,200) : $post->content!!}
Had a similar problem. I updated my Genymotion and my android SDK's/libraries/dependencies and all seemed to work. To update my SDK's I used android sdk manager {ANDROID_SDK_FOLDER}/tools/android sdk
I think you should consider using IO.binread("/path/to/file")
if you have a recent ruby interpreter (i.e. >= 1.9.2)
You could find IO
class documentation here http://www.ruby-doc.org/core-2.1.2/IO.html
Just set an onload function on the body:
<body onload="init()">
Then do something like this in javascript:
function init() {
var someimage = 'changableBackgroudImage';
document.body.style.background = 'url(img/'+someimage+'.png) no-repeat center center'
}
You can change the 'someimage' variable to whatever you want depending on some conditions, such as the time of day or something, and that image will be set as the background image.
If you get an "always true/fails" warning you may need to cast to Any before using is
(foo as Any) is SomeClass
There are two ways to handle the situation where we do not want the index to be stored in csv file.
As others have stated you can use index=False while saving your
dataframe to csv file.
df.to_csv('file_name.csv',index=False)
df.to_csv(' file_name.csv ')
df_new = pd.read_csv('file_name.csv').drop(['unnamed 0'],axis=1)
If you need to change HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state\Parameters\AllowRemoteConnection to 1, remember to restart the ASP.net state service after you change the parameter.
This adds custom text at the beginning of your file:
echo 'your_custom_escaped_content' > temp_file.csv
cat testfile.csv >> temp_file.csv
mv temp_file.csv testfile.csv
let's consider the final output rendered to the user of what we want to achieve: a padded textarea with both a border and a padding, which characteristics are that being clicked they pass the focus to our textarea, and the advantage of an automatic 100% width typical of block elements.
The best approach in my opinion is to use low level solutions as far as possible, to reach the maximum browsers support. In this case the only HTML could work fine, avoiding the use of Javascript (which anyhow we all love).
The LABEL tag comes in our help because has such behaviour and is allowed to contain the input elements it must address to. Its default style is the one of inline elements, so, giving to the label a block display style we can avail ourselves of the automatic 100% width including padding and borders, while the inner textarea has no border, no padding and a 100% width.
Taking a look at the W3C specifics other advantages we may notice are:
See W3C specifics for more detailed information.
Simple example:
.container { _x000D_
width: 400px; _x000D_
border: 3px _x000D_
solid #f7c; _x000D_
}_x000D_
.textareaContainer {_x000D_
display: block;_x000D_
border: 3px solid #38c;_x000D_
padding: 10px;_x000D_
}_x000D_
textarea { _x000D_
width: 100%; _x000D_
margin: 0; _x000D_
padding: 0; _x000D_
border-width: 0; _x000D_
}
_x000D_
<body>_x000D_
<div class="container">_x000D_
I am the container_x000D_
<label class="textareaContainer">_x000D_
<textarea name="text">I am the padded textarea with a styled border...</textarea>_x000D_
</label>_x000D_
</div>_x000D_
</body>
_x000D_
The padding and border of the .textareaContainer elements are the ones we want to give to the textarea. Try editing them to style it as you want. I gave large and visible padding and borders to the .textareaContainer element to let you see their behaviour when clicked.
There are 2 possibilities for this problem :
just check on your Google developer console for that 2 items
Make the radio component as dumb component and pass props to from parent.
import React from "react";
const Radiocomponent = ({ value, setGender }) => (
<div onChange={setGender.bind(this)}>
<input type="radio" value="MALE" name="gender" defaultChecked={value ==="MALE"} /> Male
<input type="radio" value="FEMALE" name="gender" defaultChecked={value ==="FEMALE"}/> Female
</div>
);
export default Radiocomponent;
Two ways to implement a Caesar Cipher:
Option 1: Change chars to ASCII numbers, then you can increase the value, then revert it back to the new character.
Option 2: Use a Map map each letter to a digit like this.
A - 0
B - 1
C - 2
etc...
With a map you don't have to re-calculate the shift every time. Then you can change to and from plaintext to encrypted by following map.
The answer (which I know is not what you're looking for) is:
class SpecialDerived : Base
{
public override void Say()
{
Console.WriteLine("Called from Special Derived.");
base.Say();
}
}
The truth is, you only have direct interaction with the class you inherit from. Think of that class as a layer - providing as much or as little of it or its parent's functionality as it desires to its derived classes.
EDIT:
Your edit works, but I think I would use something like this:
class Derived : Base
{
protected bool _useBaseSay = false;
public override void Say()
{
if(this._useBaseSay)
base.Say();
else
Console.WriteLine("Called from Derived");
}
}
Of course, in a real implementation, you might do something more like this for extensibility and maintainability:
class Derived : Base
{
protected enum Mode
{
Standard,
BaseFunctionality,
Verbose
//etc
}
protected Mode Mode
{
get; set;
}
public override void Say()
{
if(this.Mode == Mode.BaseFunctionality)
base.Say();
else
Console.WriteLine("Called from Derived");
}
}
Then, derived classes can control their parents' state appropriately.
It sounds like it's your browser caching the image (which I now notice you wrote in your question). You can force the browser to reload the image by passing an extra variable like so:
d = new Date();
$("#myimg").attr("src", "/myimg.jpg?"+d.getTime());
Use hasClass('in')
. It will return true if modal is in OPEN
state.
E.g:
if($('.modal').hasClass('in')){
//Do something here
}
You do like this. the function return the old text.
$('button').click(function(){
$(this).text(function(i,old){
return old=='Read More' ? 'Read Less' : 'Read More';
});
});
For those who have TypeScript installed as a local package (and possibly as a dev dependency) via:
$ npm install typescript --save-dev
...and who have added tsc script to package.json:
"scripts": {
...
"tsc": "tsc"
},
You can call tsc --init
via npm
:
$ npm run tsc -- --init
I had the same issue for another secure page when using wget
or file_get_contents
. A lot of research (including some of the responses on this question) resulted in a simple solution - installing Curl and PHP-Curl - If I've understood correctly, Curl has the Root CA for Comodo which resolved the issue
Install Curl and PHP-Curl addon, then restart Apache
sudo apt-get install curl
sudo apt-get install php-curl
sudo /etc/init.d/apache2 reload
All now working.
If you want to redirect previous location or last request then you have to include user_agent

its working for me.
The following works in Firefox interestingly enough if I remove the write line it doesn't work. Anyone have any insight why the write line is needed.

Here is couple of ways to calculate length of variable :
echo ${#VAR}
echo -n $VAR | wc -m
echo -n $VAR | wc -c
printf $VAR | wc -m
expr length $VAR
expr $VAR : '.*'
and to set the result in another variable just assign above command with back quote into another variable as following:
otherVar=`echo -n $VAR | wc -m`
echo $otherVar
http://techopsbook.blogspot.in/2017/09/how-to-find-length-of-string-variable.html
In percentage :
$('.your-class').click(function (e){
var $this = $(this); // or use $(e.target) in some cases;
var offset = $this.offset();
var width = $this.width();
var height = $this.height();
var posX = offset.left;
var posY = offset.top;
var x = e.pageX-posX;
x = parseInt(x/width*100,10);
x = x<0?0:x;
x = x>100?100:x;
var y = e.pageY-posY;
y = parseInt(y/height*100,10);
y = y<0?0:y;
y = y>100?100:y;
console.log(x+'% '+y+'%');
});
From your log its clear that numpy

A double quote character ("
) can be escaped as "
, but here's the rest of the story...
In XML attributes delimited by double quotes:
<EscapeNeeded name="Pete "Maverick" Mitchell"/>
In XML textual content:
<NoEscapeNeeded>He said, "Don't quote me."</NoEscapeNeeded>
In XML attributes delimited by single quotes ('
):
<NoEscapeNeeded name='Pete "Maverick" Mitchell'/>
Similarly, ('
) require no escaping if ("
) are used for the attribute value delimiters:
<NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>

The cut command is designed for this exact situation. It will "cut" on any delimiter and then you can specify which chunks should be output.
For instance:
echo "foo bar <foo> bla 1 2 3.4" | cut -d " " -f 6-7
Will result in output of:
2 3.4
-d sets the delimiter
-f selects the range of 'fields' to output, in this case, it's the 6th through 7th chunks of the original string. You can also specify the range as a list, such as 6,7
.

Its boils down to this: math.h
is from C
and was created over 10 years ago. In math.h, due to its primitive nature, the abs()
function is "essentially" just for integer types and if you wanted to get the absolute value of a double, you had to use fabs()
.
When C++ was created it took math.h
and made it cmath
. cmath
is essentially math.h but improved for C++. It improved things like having to distinguish between fabs()
and abs, and just made abs()
for both doubles and integer types.
In summary either:
Use math.h and use abs()
for integers, fabs()
for doubles
or
use cmath and just have abs for everything (easier and recommended)
Hope this helps anyone who is having the same problem!

This has a few possible advantages, depending on your use-case. They are explained in more detail here, but I'll give a brief overview:
This mainly makes it useful for things like configuration dictionaries.
I'm surprised that the answers here got so many upvotes when none of them really answer the question. Here's how to make sure that ONLY LATIN characters are in a given string.
const hasOnlyLetters = !!value.match(/^[a-z]*$/i);
The !!
takes transforms something that's not boolean into a boolean value. (It's exactly the same as applying a !
twice, and in fact you can use as many !
as you'd like to toggle the truthiness multiple times.)
As for the RegEx, here's the breakdown.
/.../i
The delimiter is a /
and the i
means to assess the statement in a case-insensitive fashion.^...$
The ^
means to look at the very beginning of a string. The $
means to look at the end of the string, and when used together, it means to consider the entire string. You can add more to the RegEx outside of these boundaries for things like appending/prepending a required suffix or prefix.[a-z]*
This part says to look for all lowercase letters. (The case-insensitive modifier means that we don't need to look at uppercase letters, too.) The *
at the end says that we should match whats in the brackets any number of times. That way "abc" will match instead of just "a" or "b", and so forth.Crazy. I know.
Tried all options here. Restarting, cleaning, manually checking in generated DLLs (this is invaluable to understanding if it's actually yourself that messed up).

Note the following is functionally different to Gordon Linoff's answer. His answer assumes that you want to use email2
if email
is NULL. Mine assumes you want to use email2
if email
is an empty-string. The correct answer will depend on your database (or you could perform a NULL check and an empty-string check - it all depends on what is appropriate for your database design).
SELECT `id` , `naam`
FROM `klanten`
WHERE `email` LIKE '%[email protected]%'
OR (LENGTH(email) = 0 AND `email2` LIKE '%[email protected]%')

You can not do that...
via css the URL
you put on the background-image
is just for the image.
Via HTML
you have to add the href
for your hyperlink in this way:
<a href="http://home.com" id="logo">Your logo</a>
With text-indent
and some other css
you can adjust your a element to show just the image and clicking on it you will go to your link.
EDIT:
I'm here again to show you and explain why my solution is much better:
<a href="http://home.com" id="logo">Your logo name</a>
This block of HTML
is SEO friendly because you have some text inside your link!
How to style it with css:
#logo {
background-image: url(images/logo.png);
display: block;
margin: 0 auto;
text-indent: -9999px;
width: 981px;
height: 180px;
}
Then if you don't care about SEO good to choose the other answer.
You can use the function toprettyxml()
from xml.dom.minidom
in order to do that:
def prettify(elem):
"""Return a pretty-printed XML string for the Element.
"""
rough_string = ElementTree.tostring(elem, 'utf-8')
reparsed = minidom.parseString(rough_string)
return reparsed.toprettyxml(indent="\t")
The idea is to print your Element
in a string, parse it using minidom and convert it again in XML using the toprettyxml
function.

To answer one of the questions, it is necessary to have both a global and local install for the tools to work.
If you try to run ng serve
on an application without the local install of the CLI (global install only), you will get the following error.
You have to be inside an Angular CLI project in order to use the serve command.
It will also print this message:
Please take the following steps to avoid issues:
"npm install --save-dev @angular/cli@latest"
Run that npm
command to update the CLI locally, and avoid the warning that you are getting.
Other question: It looks like they do not have to be in sync, but it's probably best that they are in order to avoid any unusual behavior with the tool, or any inconsistencies with the code the tool generates.
Why do we need both the global install, and a local install?
The global install is needed to start a new application. The ng new <app-name>
command is run using the global installation of the CLI. In fact, if you try to run ng new
while inside the folder structure of an existing CLI application, you get this lovely error:
You cannot use the
new
command inside an Angular CLI project.
Other commands that can be run from the global install are ng help
, ng get/set
with the --global
option, ng version
, ng doc
, and ng completion
.
The local install of the CLI is used after an application has been built. This way, when new versions of the CLI are available, you can update your global install, and not affect the local install. This is good for the stability of a project. Most ng
commands only make sense with the local version, like lint
, build
and serve
, etc.
According to the CLI GitHub readme, to update the CLI you must update the global and local package. However, I have used the CLI where the global and local version vary without any trouble so far. If I ever run across an error related to having the global and local CLI versions out of sync, I will post that here.
After git commit -m "{your commit message}"
, you will get a commit hash before the push.
So you can see what you are about to push with git
by running the following command:
git diff origin/{your_branch_name} commit hash
e.g: git diff origin/master c0e06d2
Matrix m
with size 3 rows and 5 columns (remove .fill(0)
to not init by zero)
[...Array(3)].map(x=>Array(5).fill(0))
let Array2D = (r,c) => [...Array(r)].map(x=>Array(c).fill(0));
let m = Array2D(3,5);
m[1][0] = 2; // second row, first column
m[2][4] = 8; // last row, last column
// print formated array
console.log(JSON.stringify(m)
.replace(/(\[\[)(.*)(\]\])/g,'[\n [$2]\n]').replace(/],/g,'],\n ')

I came across this when I wanted to make the axis labels smaller, but leave everything else the same size. The command that worked for me, was to put:
par(cex.axis=0.5)
Before the plot command. Just remember to put:
par(cex.axis=1.0)
After the plot to make sure that the fonts go back to the default size.
Ready-to-use solution that converts all PNG in the current folder to a PDF, inspired by @ilovecomputer's answer:
import glob, PIL.Image
L = [PIL.Image.open(f) for f in glob.glob('*.png')]
L[0].save('out.pdf', "PDF" ,resolution=100.0, save_all=True, append_images=L[1:])
Nothing else than PIL is needed :)
First use this Namespace:
using System.Drawing;
Add this anywhere on your form:
listBox.DrawMode = DrawMode.OwnerDrawFixed;
listBox.DrawItem += listBox_DrawItem;
Here is the Event Handler:
private void listBox_DrawItem(object sender, DrawItemEventArgs e)
{
e.DrawBackground();
Graphics g = e.Graphics;
g.FillRectangle(new SolidBrush(Color.White), e.Bounds);
ListBox lb = (ListBox)sender;
g.DrawString(lb.Items[e.Index].ToString(), e.Font, new SolidBrush(Color.Black), new PointF(e.Bounds.X, e.Bounds.Y));
e.DrawFocusRectangle();
}
If you have @oneToOne
mapping set to FetchType.LAZY
and you use second query (because you need Department objects to be loaded as part of Employee objects) what Hibernate will do is, it will issue queries to fetch Department objects for every individual Employee object it fetches from DB.
Later, in the code you might access Department objects via Employee to Department single-valued association and Hibernate will not issue any query to fetch Department object for the given Employee.
Remember, Hibernate still issues queries equal to the number of Employees it has fetched. Hibernate will issue same number of queries in both above queries, if you wish to access Department objects of all Employee objects
You can use a pseudo element to create the overlay.
.testclass {
background-image: url("../img/img.jpg");
position: relative;
}
.testclass:before {

Use public property of child form
frmOptions {
public string Result; }
frmMain {
frmOptions.ShowDialog(); string r = frmOptions.Result; }
Use events
frmMain {
frmOptions.OnResult += new ResultEventHandler(frmMain.frmOptions_Resukt);
frmOptions.ShowDialog(); }
Use public property of main form
frmOptions {
public frmMain MainForm; MainForm.Result = "result"; }
frmMain {
public string Result;
frmOptions.MainForm = this;
frmOptions.ShowDialog();
string r = this.Result; }
Use object Control.Tag; This is common for all controls public property which can contains a System.Object. You can hold there string or MyClass or MainForm - anything!
frmOptions {
this.Tag = "result": }
frmMain {
frmOptions.ShowDialog();
string r = frmOptions.Tag as string; }
from the man page
linux$ man -S 5 crontab
cron(8) examines cron entries once every minute.
The time and date fields are:
field allowed values
----- --------------
minute 0-59
hour 0-23
day of month 1-31
month 1-12 (or names, see below)
day of week 0-7 (0 or 7 is Sun, or use names)
...
# run five minutes after midnight, every day
5 0 * * * $HOME/bin/daily.job >> $HOME/tmp/out 2>&1
...
It is good to note the special "nicknames" that can be used (documented in the man page), particularly "@reboot" which has no time and date alternative.
# Run once after reboot.
@reboot /usr/local/sbin/run_only_once_after_reboot.sh
You can also use this trick to run your cron job multiple times per minute.
# Run every minute at 0, 20, and 40 second intervals
* * * * * sleep 00; /usr/local/sbin/run_3times_per_minute.sh
* * * * * sleep 20; /usr/local/sbin/run_3times_per_minute.sh
* * * * * sleep 40; /usr/local/sbin/run_3times_per_minute.sh
To add a cron job, you can do one of three things:
add a command to a user's crontab, as shown above (and from the crontab, section 5, man page).
crontab -e -u <username>
crontab -e
EDITOR
environment variable
env EDITOR=nano crontab -e -u <username>
export EDITOR=vim
crontab -e
chmod a+x <file>
create a script/program as a cron job, and add it to the system's anacron /etc/cron.*ly
directories
chmod a+x /etc/cron.daily/script_runs_daily.sh
-- make it executableman anacron
chmod a+x <file>
/etc/crontab
or /etc/anacrontab
to run at a set time/etc/anacrontab
, and define cron.hourly in /etc/cron.d/0hourly
Or, One can create system crontables in /etc/cron.d
.
/etc/cron.d
do not need to be executable.someuser
, and the use of /bin/bash
as the shell is forced. File: /etc/cron.d/myapp-cron
# use /bin/bash to run commands, no matter what /etc/passwd says
SHELL=/bin/bash
# Execute a nightly (11:00pm) cron job to scrub application records
00 23 * * * someuser /opt/myapp/bin/scrubrecords.php
Ran into this issue with Parallels and VS 2013. Command + Insert also fixed it in my setup, in addition to the accepted answer. On my Windows USB keyboard Command == WindowsKey.
My problem was that I had other libraries that my project referenced and those libraries had another version of appcompat referenced. This is what I did to resolve the issue:
(You should back up your project before doing this)
1) I deleted all the appcompat layout folders (ex: /res/layout-v11).
2) Solved the problems that arose from that, usually an error in menu.xml
3) Back to main project and add appcompat library, clean, and everything works!
XSD:
XSD (XML Schema Definition) specifies how to formally describe the elements in an Extensible Markup Language (XML) document.
Xml:
XML was designed to describe data.It is independent from software as well as hardware.
It enhances the following things.
-Data sharing.
-Platform independent.
-Increasing the availability of Data.
Differences:
XSD is based and written on XML.
XSD defines elements and structures that can appear in the document, while XML does not.
XSD ensures that the data is properly interpreted, while XML does not.
An XSD document is validated as XML, but the opposite may not always be true.
XSD is better at catching errors than XML.
An XSD defines elements that can be used in the documents, relating to the actual data with which it is to be encoded.
for eg:
A date that is expressed as 1/12/2010 can either mean January 12 or December 1st. Declaring a date data type in an XSD document, ensures that it follows the format dictated by XSD.
Your makefile should ideally be named makefile
, not make
. Note that you can call your makefile anything you like, but as you found, you then need the -f
option with make
to specify the name of the makefile. Using the default name of makefile
just makes life easier.
position: fixed;
will also "pop" an element out of the flow, as you say. :)
position: absolute
must be accompanied by a position. e.g. top: 1rem; left: 1rem
position: fixed
however, will place the element where it would normally appear according to the document flow, but prevent it from moving after that. It also effectively set's the height to 0px (with regards to the dom) so that the next element shifts up over it.
This can be pretty cool, because you can set position: fixed; z-index: 1
(or whatever z-index you need) so that it "pops" over the next element.
This is especially useful for fixed position headers that stay at the top when you scroll, for example.
The original solution (setting the ForkJoinPool common parallelism property) no longer works. Looking at the links in the original answer, an update which breaks this has been back ported to Java 8. As mentioned in the linked threads, this solution was not guaranteed to work forever. Based on that, the solution is the forkjoinpool.submit with .get solution discussed in the accepted answer. I think the backport fixes the unreliability of this solution also.
ForkJoinPool fjpool = new ForkJoinPool(10);
System.out.println("stream.parallel");
IntStream range = IntStream.range(0, 20);
fjpool.submit(() -> range.parallel()
.forEach((int theInt) ->
{
try { Thread.sleep(100); } catch (Exception ignore) {}
System.out.println(Thread.currentThread().getName() + " -- " + theInt);
})).get();
System.out.println("list.parallelStream");
int [] array = IntStream.range(0, 20).toArray();
List<Integer> list = new ArrayList<>();
for (int theInt: array)
{
list.add(theInt);
}
fjpool.submit(() -> list.parallelStream()
.forEach((theInt) ->
{
try { Thread.sleep(100); } catch (Exception ignore) {}
System.out.println(Thread.currentThread().getName() + " -- " + theInt);
})).get();
<activity
...
android:windowSoftInputMode="stateVisible" >

or
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

You can send it as raw xml
<test>or like this</test>
If you declare the paramater2 as XElement data type
In a text area, as in the form input, then just a normal line break will work:
<textarea>
This is a text area
line breaks are automatic
</textarea>
If you're talking about normal text on the page, the <br /> (or just <br> if using plain 'ole HTML4) is a line break.
However, I'd say that you often don't actually want a line break. Usually, your text is seperated into paragraphs:
<p>
This is some text
</p>
<p>
This is some more
</p>
Which is much better because it gives a clue as to how your text is structured to machines that read it. Machines that read it include screen readers for the partially sighted or blind, seperating text into paragraphs gives it a chance of being presented correctly to these users.
To my knowledge, Ejabberd (http://www.ejabberd.im/) is the parent, this is XMPP server which provide quite good features of open source, Whatsapp uses some modified version of this, facebook messaging also uses a modified version of this. Some more chat applications likes Samsung's ChatOn, Nimbuzz messenger all use ejabberd based ones and Erlang solutions also have modified version of this ejabberd which they claim to be highly scalable and well tested with more performance improvements and renamed as MongooseIM.
Ejabberd is the server which has most of the featured implemented when compared to other. Since it is build in Erlang it is highly scalable horizontally.
Map.keys()
returns a MapIterator
object which can be converted to Array
using Array.from
:
let keys = Array.from( myMap.keys() );
// ["a", "b"]
EDIT: you can also convert iterable object to array using spread syntax
let keys =[ ...myMap.keys() ];
// ["a", "b"]
for a single line implementation, you can use a lambda expression in a map
map(lambda x:MyModel.objects.get_or_create(name=x), items)
Here, lambda matches each item in items list to x and create a Database record if necessary.
A few other things:
Based on acheron55 answer I posted a possible implementation here.
Here is a brief summery of it:
All you have to do, is to keep track of the path through which the target has been reached.
A simple way to do it, is to push into the Queue
the whole path used to reach a node, rather than the node itself.
The benefit of doing so is that when the target has been reached the queue holds the path used to reach it.
This is also applicable to cyclic graphs, where a node can have more than one parent.
The return true
part of this only tells the text field whether or not it is allowed to return.
You have to manually tell the text field to dismiss the keyboard (or what ever its first responder is), and this is done with resignFirstResponder()
, like so:
// Called on 'Return' pressed. Return false to ignore.
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}

This is an answer to question 8391979, "Does java have a int.tryparse that doesn't throw an exception for bad data? [duplicate]" which is closed and linked to this question.
Edit 2016 08 17: Added ltrimZeroes methods and called them in tryParse(). Without leading zeroes in numberString may give false results (see comments in code). There is now also public static String ltrimZeroes(String numberString) method which works for positive and negative "numbers"(END Edit)

BH's answer of installing Java 6u45 was very close... still got the popup on reboot...BUT after uninstalling Java 6u45, rebooted, no warning! Thank you BH! Then installed the latest version, 8u151-i586, rebooted no warning.
I added lines in PATH as above, didn't do anything.
My system: Windows 7, 64 bit. Warning was for No JVM, 32 bit Java not found. Yes, I could have installed the 64 bit version, but 32bit is more compatible with all programs.

Check your .npmrc
file for a registry
entry (which identifies a server acting as a package cache.)
For me, npm install
would hang partway through, and it was because of a old / non-responsive server listed in my .npmrc
file. Remove the line or comment it out:
>cat ~/.npmrc
#registry=http://oldserver:4873
(And/or check with your IT / project lead as to why it's not working ;)
Use the following commands to find the php.ini
file path in linux.
[root@AnyDirectory ~]# locate php.ini
/etc/php.ini
/etc/php.ini.rpmnew
/usr/share/doc/php-common-5.4.45/php.ini-development
/usr/share/doc/php-common-5.4.45/php.ini-production
or try this another way
[root@AnyDirectory ~]# php --ini
its shows the path result
Try this:
SELECT *
FROM (SELECT * FROM (
SELECT
id,
client_id,
create_time,
ROW_NUMBER() OVER(PARTITION BY client_id ORDER BY create_time DESC) rn
FROM order
)
WHERE rn=1
ORDER BY create_time desc) alias_name
WHERE rownum <= 100
ORDER BY rownum;
Or TOP:
SELECT TOP 2 * FROM Customers; //But not supported in Oracle
NOTE: I suppose that your internal query is fine. Please share your output of this.
The HashMap has forEach
as part of its structure. You can use that with a lambda expression to print out the contents in a one liner such as:
map.forEach((k,v)-> System.out.println(k+", "+v));
or
map.forEach((k,v)-> System.out.println("key: "+k+", value: "+v));
Lets say your data is -
data = {'a': [ [1, 2] ], 'b': [ [3, 4] ],'c':[ [5,6]] }
You can use the data.items()
method to get the dictionary elements. Note, in django templates we do NOT put ()
. Also some users mentioned values[0]
does not work, if that is the case then try values.items
.
<table>
<tr>
<td>a</td>
<td>b</td>
<td>c</td>
</tr>
{% for key, values in data.items %}
<tr>
<td>{{key}}</td>
{% for v in values[0] %}
<td>{{v}}</td>
{% endfor %}
</tr>
{% endfor %}
</table>
Am pretty sure you can extend this logic to your specific dict.
To iterate over dict keys in a sorted order - First we sort in python then iterate & render in django template.
return render_to_response('some_page.html', {'data': sorted(data.items())})
In template file:
{% for key, value in data %}
<tr>
<td> Key: {{ key }} </td>
<td> Value: {{ value }} </td>
</tr>
{% endfor %}
For those using Bootstrap 3 code below will clean whole form: messages, icons and colors...
$('.form-group').each(function () { $(this).removeClass('has-success'); });
$('.form-group').each(function () { $(this).removeClass('has-error'); });
$('.form-group').each(function () { $(this).removeClass('has-feedback'); });
$('.help-block').each(function () { $(this).remove(); });
$('.form-control-feedback').each(function () { $(this).remove(); });
In case, if anyone prefers a simpler solution, especially on Linux (e.g. Ubuntu), a very easy way out is to create a symbolic link to the intended folder in the htdocs folder. For example, if I want to be able to serve files from a folder called "/home/some/projects/testserver/" and my htdocs is located in "/opt/lampp/htdocs/". Just create a symbolic link like so:
ln -s /home/some/projects/testserver /opt/lampp/htdocs/testserver
The command for symbolic link works like so:
ln -s target source
where,
target - The existing file/directory you would like to link TO.
source - The file/folder to be created, copying the contents of the target. The LINK itself.
For more help see ln --help Source: Create Symbolic Links in Ubuntu
And that's done. just visit http://localhost/testserver/ In fact, you don't even need to restart your server.

exec sp_lock
This query should give you existing locks.
exec sp_who SPID -- will give you some info
Having spids, you could check activity monitor(processes tab) to find out what processes are locking the tables ("details" for more info and "kill process" to kill it).
I would suggest looking into minifying the files first and see if that gives you a big enough speed boost. If your host is slow, could try putting that static content on a CDN.
add JAVA_HOME to the file:
/etc/environment
for it to be available to the entire system (you would need to restart Ubuntu though)
I ran into this problem when SQL Server 2014 standard was installed on a server where SQL Server Express was also installed. I had opened SSMS from a desktop shortcut, not realizing right away that it was SSMS for SQL Server Express, not for 2014. SSMS for Express returned the error, but SQL Server 2014 did not.
When your activity is recreated after it was previously destroyed, you can recover your saved state from the Bundle that the system passes your activity. Both the onCreate() and onRestoreInstanceState() callback methods receive the same Bundle that contains the instance state information.
Because the onCreate() method is called whether the system is creating a new instance of your activity or recreating a previous one, you must check whether the state Bundle is null before you attempt to read it. If it is null, then the system is creating a new instance of the activity, instead of restoring a previous one that was destroyed.
static final String STATE_USER = "user";
private String mUser;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Check whether we're recreating a previously destroyed instance
if (savedInstanceState != null) {
// Restore value of members from saved state
mUser = savedInstanceState.getString(STATE_USER);
} else {
// Probably initialize members with default values for a new instance
mUser = "NewUser";
}
}
@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
savedInstanceState.putString(STATE_USER, mUser);
// Always call the superclass so it can save the view hierarchy state
super.onSaveInstanceState(savedInstanceState);

I can understand your pain. In my case the error got resolved by performing below steps:
Hope this helps.
The most beginner-friendly solution is:
Drag a Timer from the Toolbox, give it a Name, set your desired Interval, and set "Enabled" to True. Then double-click the Timer and Visual Studio (or whatever you are using) will write the following code for you:
private void wait_Tick(object sender, EventArgs e)
{
refreshText(); // Add the method you want to call here.
}
No need to worry about pasting it into the wrong code block or something like that.
select * from my_table where my_field Like '[a-z][a-z]%'

On Windows gvim just select "Lucida Console" font.
for me encoding with utf16 worked
file = open('filename.csv', encoding="utf16")
I could be wrong but I thought it used IE's proxy settings.
If it sees that you need to login it opens a dialog and asks you to do so (login that is).

I'm not sure what you really want to do, but my guess is you want your C++ program to output colored text in the console, right ? Don't know about Windows, but on all Unices (including Mac OS X), you'd simply use ANSI escape sequences for that.
