I recently encountered the same problem, and I will try to generalise how I solved it, as a lot of these answers are to spesific to be of help to everyone.
1. First look at the bottom of the error message to identify the file and function which causes the segmentation fault.
2. Then I look at that function and commented out all of it. I compiled and it now worked. Then I removed the comments from parts of the function at a time, until I hit the line that was responsible for the error. After this I was able to fix it, and it all works. :)
You want the (standard) POSIXt
type from base R that can be had in 'compact form' as a POSIXct
(which is essentially a double representing fractional seconds since the epoch) or as long form in POSIXlt
(which contains sub-elements). The cool thing is that arithmetic etc are defined on this -- see help(DateTimeClasses)
Quick example:
R> now <- Sys.time()
R> now
[1] "2009-12-25 18:39:11 CST"
R> as.numeric(now)
[1] 1.262e+09
R> now + 10 # adds 10 seconds
[1] "2009-12-25 18:39:21 CST"
R> as.POSIXlt(now)
[1] "2009-12-25 18:39:11 CST"
R> str(as.POSIXlt(now))
POSIXlt[1:9], format: "2009-12-25 18:39:11"
R> unclass(as.POSIXlt(now))
$sec
[1] 11.79
$min
[1] 39
$hour
[1] 18
$mday
[1] 25
$mon
[1] 11
$year
[1] 109
$wday
[1] 5
$yday
[1] 358
$isdst
[1] 0
attr(,"tzone")
[1] "America/Chicago" "CST" "CDT"

As for reading them in, see help(strptime)
As for difference, easy too:
R> Jan1 <- strptime("2009-01-01 00:00:00", "%Y-%m-%d %H:%M:%S")
R> difftime(now, Jan1, unit="week")
Time difference of 51.25 weeks

Lastly, the zoo package is an extremely versatile and well-documented container for matrix with associated date/time indices.
struct timeval contains two components, the second and the microsecond. A timestamp with microsecond precision is represented as seconds since the epoch stored in the tv_sec field and the fractional microseconds in tv_usec. Thus you cannot just ignore tv_sec and expect sensible results.
If you use Linux or *BSD, you can use timersub() to subtract two struct timeval values, which might be what you want.
Example of a Boolean (AND) plus Wildcard search, which I'm using inside a javascript Autocomplete plugin:
String to match: "my word"
String to search: "I'm searching for my funny words inside this text"
You need the following regex: /^(?=.*my)(?=.*word).*$/im
Explaining:
^ assert position at start of a line
?= Positive Lookahead
.* matches any character (except newline)
() Groups
$ assert position at end of a line
i modifier: insensitive. Case insensitive match (ignores case of [a-zA-Z])
m modifier: multi-line. Causes ^ and $ to match the begin/end of each line (not only begin/end of string)
Test the Regex here: https://regex101.com/r/iS5jJ3/1
So, you can create a javascript function that:
Example:
function fullTextCompare(myWords, toMatch){_x000D_
//Replace regex reserved characters_x000D_
myWords=myWords.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');_x000D_
//Split your string at spaces_x000D_
arrWords = myWords.split(" ");_x000D_
//Encapsulate your words inside regex groups_x000D_
arrWords = arrWords.map(function( n ) {_x000D_
return ["(?=.*"+n+")"];_x000D_
});_x000D_
//Create a regex pattern_x000D_
sRegex = new RegExp("^"+arrWords.join("")+".*$","im");_x000D_
//Execute the regex match_x000D_
return(toMatch.match(sRegex)===null?false:true);_x000D_
}_x000D_
_x000D_
//Using it:_x000D_
console.log(_x000D_
fullTextCompare("my word","I'm searching for my funny words inside this text")_x000D_
);_x000D_
_x000D_
//Wildcards:_x000D_
console.log(_x000D_
fullTextCompare("y wo","I'm searching for my funny words inside this text")_x000D_
);
_x000D_
To search the whole computer:
gdr -PSProvider 'FileSystem' | %{ ls -r $_.root} 2>$null | where { $_.name -eq "httpd.exe" }
In pgAdmin you can also use
SET search_path TO your_db_name;
Use WinSCP for file transfer over SSH, putty is only for SSH commands.
I'm not sure what you mean by "myself".
Any JavaScript function can be called by an event, but you must have some sort of event to trigger it.
e.g. On page load:
<body onload="myfunction();">
Or on mouseover:
<table onmouseover="myfunction();">
As a result the first question is, "What do you want to do to cause the function to execute?"
After you determine that it will be much easier to give you a direct answer.
You need to access the matches in order to get at the SDI number. Here is a function that will do it (assuming there is only 1 SDI number per cell).
For the regex, I used "sdi followed by a space and one or more numbers". You had "sdi followed by a space and zero or more numbers". You can simply change the + to * in my pattern to go back to what you had.
Function ExtractSDI(ByVal text As String) As String
Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")
RE.pattern = "(sdi \d+)"
RE.Global = True
RE.IgnoreCase = True
Set allMatches = RE.Execute(text)
If allMatches.count <> 0 Then
result = allMatches.Item(0).submatches.Item(0)
End If
ExtractSDI = result
End Function
If a cell may have more than one SDI number you want to extract, here is my RegexExtract function. You can pass in a third paramter to seperate each match (like comma-seperate them), and you manually enter the pattern in the actual function call:
Ex) =RegexExtract(A1, "(sdi \d+)", ", ")
Here is:
Function RegexExtract(ByVal text As String, _
ByVal extract_what As String, _
Optional seperator As String = "") As String
Dim i As Long, j As Long
Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")
RE.pattern = extract_what
RE.Global = True
Set allMatches = RE.Execute(text)
For i = 0 To allMatches.count - 1
For j = 0 To allMatches.Item(i).submatches.count - 1
result = result & seperator & allMatches.Item(i).submatches.Item(j)
Next
Next
If Len(result) <> 0 Then
result = Right(result, Len(result) - Len(seperator))
End If
RegexExtract = result
End Function
*Please note that I have taken "RE.IgnoreCase = True" out of my RegexExtract, but you could add it back in, or even add it as an optional 4th parameter if you like.
[[ -f ./${sname} ]] && read -p "File exists. Are you sure? " -n 1
[[ ! $REPLY =~ ^[Yy]$ ]] && exit 1
used this in a function to look for an existing file and prompt before overwriting.
Comparator
is a functional interface, and Integer::max
complies with that interface (after autoboxing/unboxing is taken into consideration). It takes two int
values and returns an int
- just as you'd expect a Comparator<Integer>
to (again, squinting to ignore the Integer/int difference).
However, I wouldn't expect it to do the right thing, given that Integer.max
doesn't comply with the semantics of Comparator.compare
. And indeed it doesn't really work in general. For example, make one small change:
for (int i = 1; i <= 20; i++)
list.add(-i);
... and now the max
value is -20 and the min
value is -1.
Instead, both calls should use Integer::compare
:
System.out.println(list.stream().max(Integer::compare).get());
System.out.println(list.stream().min(Integer::compare).get());
First off, this actually is being raised in the next version to 8MB
or 16MB
... but I think to put this into perspective, Eliot from 10gen (who developed MongoDB) puts it best:
EDIT: The size has been officially 'raised' to 16MB
So, on your blog example, 4MB is actually a whole lot.. For example, the full uncompresses text of "War of the Worlds" is only 364k (html): http://www.gutenberg.org/etext/36
If your blog post is that long with that many comments, I for one am not going to read it :)
For trackbacks, if you dedicated 1MB to them, you could easily have more than 10k (probably closer to 20k)
So except for truly bizarre situations, it'll work great. And in the exception case or spam, I really don't think you'd want a 20mb object anyway. I think capping trackbacks as 15k or so makes a lot of sense no matter what for performance. Or at least special casing if it ever happens.
-Eliot
I think you'd be pretty hard pressed to reach the limit ... and over time, if you upgrade ... you'll have to worry less and less.
The main point of the limit is so you don't use up all the RAM on your server (as you need to load all MB
s of the document into RAM when you query it.)
So the limit is some % of normal usable RAM on a common system ... which will keep growing year on year.
Note on Storing Files in MongoDB
If you need to store documents (or files) larger than 16MB
you can use the GridFS API which will automatically break up the data into segments and stream them back to you (thus avoiding the issue with size limits/RAM.)
Instead of storing a file in a single document, GridFS divides the file into parts, or chunks, and stores each chunk as a separate document.
GridFS uses two collections to store files. One collection stores the file chunks, and the other stores file metadata.
You can use this method to store images, files, videos, etc in the database much as you might in a SQL database. I have used this to even store multi gigabyte video files.
Your assumptions don't seem to be right. After a clear()
, the newly added data start from index 0.
A 32-bit process is still limited to the same constraints in a 64-bit OS. The issue is that memory pointers are only 32-bits wide, so the program can't assign/resolve any memory address larger than 32 bits.
For the impatient:
UPDATE target AS t
INNER JOIN (
SELECT s.id, COUNT(*) AS count
FROM source_grouped AS s
-- WHERE s.custom_condition IS (true)
GROUP BY s.id
) AS aggregate ON aggregate.id = t.id
SET t.count = aggregate.count
That's @mellamokb's answer, as above, reduced to the max.
in case if your table has tbody
let tbl = document.getElementById("tbl").getElementsByTagName('tbody')[0];
console.log(tbl.rows[0].cells[0].innerHTML)
the_int=window.clearInterval(the_int);
UPDATE:
You'll also want to goto Security -> Server Roles
, and for public
check the permissions for TSQL Default TCP/TSQL Default VIA/TSQL Local Machine/TSQL Named Pipes
and remove the connect
permission
The regular expression for this is really simple. Just use a character class. The hyphen is a special character in character classes, so it needs to be first:
/[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/]/
You also need to escape the other regular expression metacharacters.
Edit: The hyphen is special because it can be used to represent a range of characters. This same character class can be simplified with ranges to this:
/[$-/:-?{-~!"^_`\[\]]/
There are three ranges. '$' to '/', ':' to '?', and '{' to '~'. the last string of characters can't be represented more simply with a range: !"^_`[].
Use an ACSII table to find ranges for character classes.

The .error

classes are appended to the .control-group
. This is standard Bootstrap markup and styling in v2. Just follow that and you're in good shape. Of course you can go beyond with your own styles to add a popup or "inline flash" if you prefer, but if you follow Bootstrap convention and hang those validation classes on the .control-group
it will stay consistent and easy to manage (at least since you'll continue to have the benefit of Bootstrap docs and examples)

According to your package.json, you're using Angular 8.3, but you've imported angular/cdk v9. You can downgrade your angular/cdk version or you can upgrade your Angular version to v9 by running:
ng update @angular/core @angular/cli
That will update your local angular version to 9. Then, just to sync material, run:
ng update @angular/material

to check button call event first we need to spy on method which will be called after button click so our first line will be spyOn spy methode take two arguments 1) component name 2) method to be spy i.e: 'onSubmit' remember not use '()' only name required then we need to make object of button to be clicked now we have to trigger the event handler on which we will add click event then we expect our code to call the submit method once
it('should call onSubmit method',() => {
spyOn(component, 'onSubmit');
let submitButton: DebugElement =
fixture.debugElement.query(By.css('button[type=submit]'));
fixture.detectChanges();
submitButton.triggerEventHandler('click',null);
fixture.detectChanges();
expect(component.onSubmit).toHaveBeenCalledTimes(1);
});
Before comparing the Dates
object, try setting both of their milliseconds to zero like Date.setMilliseconds(0);
.
In some cases where the Date
object is dynamically created in javascript, if you keep printing the Date.getTime()
, you'll see the milliseconds changing, which will prevent the equality of both dates.

name()
is a "built-in" method of enum
. It is final and you cannot change its implementation. It returns the name of enum constant as it is written, e.g. in upper case, without spaces etc.
Compare MOBILE_PHONE_NUMBER
and Mobile phone number
. Which version is more readable? I believe the second one. This is the difference: name()
always returns MOBILE_PHONE_NUMBER
, toString()
may be overriden to return Mobile phone number
.
Try this:
list.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3)
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
In Python, execution does NOT have to begin at main. The first line of "executable code" is executed first.
def main():
print("main code")
def meth1():
print("meth1")
meth1()
if __name__ == "__main__":main() ## with if
Output -
meth1
main code
More on main() - http://ibiblio.org/g2swap/byteofpython/read/module-name.html
A module's __name__
Every module has a name and statements in a module can find out the name of its module. This is especially handy in one particular situation - As mentioned previously, when a module is imported for the first time, the main block in that module is run. What if we want to run the block only if the program was used by itself and not when it was imported from another module? This can be achieved using the name attribute of the module.
Using a module's __name__
#!/usr/bin/python
# Filename: using_name.py
if __name__ == '__main__':
print 'This program is being run by itself'
else:
print 'I am being imported from another module'
Output -
$ python using_name.py
This program is being run by itself
$ python
>>> import using_name
I am being imported from another module
>>>
How It Works -
Every Python module has it's __name__
defined and if this is __main__
, it implies that the module is being run standalone by the user and we can do corresponding appropriate actions.

You can use the versionName
in XML resources, such as activity layouts. First create a string resource in the app/build.gradle
with the following snippet in the android
node:
applicationVariants.all { variant ->
variant.resValue "string", "versionName", variant.versionName
}
So the whole build.gradle
file contents may look like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion '24.0.0 rc3'
defaultConfig {
applicationId 'com.example.myapplication'
minSdkVersion 15
targetSdkVersion 23
versionCode 17
versionName '0.2.3'
jackOptions {
enabled true
}
}
applicationVariants.all { variant ->
variant.resValue "string", "versionName", variant.versionName
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.android.support:design:23.3.0'
compile 'com.android.support:support-v4:23.3.0'
}
Then you can use @string/versionName
in the XML. Android Studio will mark it red, but the app will compile without issues. For example, this may be used like this in app/src/main/res/xml/preferences.xml
:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:title="About"
android:key="pref_key_about">
<Preference
android:key="pref_about_build"
android:title="Build version"
android:summary="@string/versionName" />
</PreferenceCategory>
</PreferenceScreen>
As promised, here is my Cairo version. I scripted it with Lua, using lfs to walk the directories. I love these little challenges, as they allow me to explore APIs I wanted to dig for quite some time...
lfs and LuaCairo are both cross-platform, so it should work on other systems (tested on French WinXP Pro SP3).
I made a first version drawing file names as I walked the tree. Advantage: no memory overhead. Inconvenience: I have to specify the image size beforehand, so listings are likely to be cut off.
So I made this version, first walking the directory tree, storing it in a Lua table. Then, knowing the number of files, creating the canvas to fit (at least vertically) and drawing the names.
You can easily switch between PNG rendering and SVG one. Problem with the latter: Cairo generates it at low level, drawing the letters instead of using SVG's text capability. Well, at least, it guarantees accurate rending even on systems without the font. But the files are bigger... Not really a problem if you compress it after, to have a .svgz file.
Or it shouldn't be too hard to generate the SVG directly, I used Lua to generate SVG in the past.

Of course, you can change the styles. I didn't draw the connection lines, I didn't saw it as necessary. I might add them optionally later.
You can also use a fadeIn/FadeOut Combo, too....
$('.test').bind('click', function(){
$('.div1').fadeIn(500);
$('.div2').fadeOut(500);
$('.div3').fadeOut(500);
return false;
});
No need for cut or magic, in bash you can cut a string like so:
ORGSTRING="123456"
CUTSTRING=${ORGSTRING:0:-3}
echo "The original string: $ORGSTRING"
echo "The new, shorter and faster string: $CUTSTRING"
Why not just run this: No need for special permissions
SELECT

object_id,

This is not using Set, Map, List or any extra collection, only two arrays:
package arrays.duplicates;
import java.lang.reflect.Array;
import java.util.Arrays;
public class ArrayDuplicatesRemover<T> {
public static <T> T[] removeDuplicates(T[] input, Class<T> clazz) {
T[] output = (T[]) Array.newInstance(clazz, 0);
for (T t : input) {
if (!inArray(t, output)) {
output = Arrays.copyOf(output, output.length + 1);
output[output.length - 1] = t;
}
}
return output;
}
private static <T> boolean inArray(T search, T[] array) {
for (T element : array) {
if (element.equals(search)) {
return true;
}
}
return false;
}
}
And the main to test it
package arrays.duplicates;
import java.util.Arrays;
public class TestArrayDuplicates {
public static void main(String[] args) {
Integer[] array = {1, 1, 2, 2, 3, 3, 3, 3, 4};
testArrayDuplicatesRemover(array);
}
private static void testArrayDuplicatesRemover(Integer[] array) {
final Integer[] expectedResult = {1, 2, 3, 4};
Integer[] arrayWithoutDuplicates = ArrayDuplicatesRemover.removeDuplicates(array, Integer.class);
System.out.println("Array without duplicates is supposed to be: " + Arrays.toString(expectedResult));
System.out.println("Array without duplicates currently is: " + Arrays.toString(arrayWithoutDuplicates));
System.out.println("Is test passed ok?: " + (Arrays.equals(arrayWithoutDuplicates, expectedResult) ? "YES" : "NO"));
}
}
And the output:
Array without duplicates is supposed to be: [1, 2, 3, 4]
Array without duplicates currently is: [1, 2, 3, 4]
Is test passed ok?: YES

I was using my OpenWRT enhanced device as a repeater (which adds virtual ethernet and wireless lan capabilities) and found that the /sys/class/net/eth0 carrier and opstate values were unreliable. I played around with /sys/class/net/eth0.1 and /sys/class/net/eth0.2 as well with (at least to my finding) no reliable way to detect that something was physically plugged in and talking on any of the ethernet ports. I figured out a bit crude but seemingly reliable way to detect if anything had been plugged in since the last reboot/poweron state at least (which worked exactly as I needed it to in my case).
ifconfig eth0 | grep -o 'RX packets:[0-9]*' | grep -o '[0-9]*'
You'll get a 0 if nothing has been plugged in and something > 0 if anything has been plugged in (even if it was plugged in and since removed) since the last power on or reboot cycle.
Hope this helps somebody out at least!
If you use opacity
to a element, entire element effect that(background+other things in it),you can use mix-blend-mode
to the CSS attributes of the specific element,

Interesting discussion. I was asking myself this question too. The main difference between fluid and fixed is simply that the fixed layout has a fixed width in terms of the whole layout of the website (viewport). If you have a 960px width viewport each colum has a fixed width which will never change.
The fluid layout behaves different. Imagine you have set the width of your main layout to 100% width. Now each column will only be calculated to it's relative size (i.e. 25%) and streches as the browser will be resized. So based on your layout purpose you can select how your layout behaves.
Here is a good article about fluid vs. flex.
We encountered similar errors in a testing environment on a virtual machine. If the machine name changes due to VM cloning from a template, you can get this error.
If the computer name changed from OLD to NEW.
A job uses this stored procedure:
msdb.dbo.sp_sqlagent_has_server_access @login_name = 'OLD\Administrator'
Which uses this one:
EXECUTE master.dbo.xp_logininfo 'OLD\Administrator'
Which gives this SQL error 15404
select text from sys.messages where message_id = 15404;
Could not obtain information about Windows NT group/user '%ls', error code %#lx.
Which I guess is correct, under the circumstances. We added a script to the VM cloning/deployment process that re-creates the SQL login.
With Jenkins CLI you do not have to reload everything - you just can load the job (update-job command). You can't use tokens with CLI, AFAIK - you have to use password or password file.
Token name for user can be obtained via http://<jenkins-server>/user/<username>/configure
- push on 'Show API token' button.
Here's a link on how to use API tokens (it uses wget
, but curl
is very similar).
Here is a generalized simple command argument interface you can paste to the top of all your scripts.
#!/bin/bash
declare -A flags
declare -A booleans
args=()
while [ "$1" ];
do
arg=$1
if [ "${1:0:1}" == "-" ]
then
shift
rev=$(echo "$arg" | rev)
if [ -z "$1" ] || [ "${1:0:1}" == "-" ] || [ "${rev:0:1}" == ":" ]
then
bool=$(echo ${arg:1} | sed s/://g)
booleans[$bool]=true
echo \"$bool\" is boolean
else
value=$1
flags[${arg:1}]=$value
shift
echo \"$arg\" is flag with value \"$value\"
fi
else
args+=("$arg")
shift
echo \"$arg\" is an arg
fi
done
echo -e "\n"
echo booleans: ${booleans[@]}
echo flags: ${flags[@]}
echo args: ${args[@]}
echo -e "\nBoolean types:\n\tPrecedes Flag(pf): ${booleans[pf]}\n\tFinal Arg(f): ${booleans[f]}\n\tColon Terminated(Ct): ${booleans[Ct]}\n\tNot Mentioned(nm): ${boolean[nm]}"
echo -e "\nFlag: myFlag => ${flags["myFlag"]}"
echo -e "\nArgs: one: ${args[0]}, two: ${args[1]}, three: ${args[2]}"
By running the command:
bashScript.sh firstArg -pf -myFlag "my flag value" secondArg -Ct: thirdArg -f
The output will be this:
"firstArg" is an arg
"pf" is boolean
"-myFlag" is flag with value "my flag value"
"secondArg" is an arg
"Ct" is boolean
"thirdArg" is an arg
"f" is boolean
booleans: true true true
flags: my flag value
args: firstArg secondArg thirdArg
Boolean types:
Precedes Flag(pf): true
Final Arg(f): true
Colon Terminated(Ct): true
Not Mentioned(nm):
Flag: myFlag => my flag value
Args: one => firstArg, two => secondArg, three => thirdArg
Basically, the arguments are divided up into flags booleans and generic arguments. By doing it this way a user can put the flags and booleans anywhere as long as he/she keeps the generic arguments (if there are any) in the specified order.
Allowing me and now you to never deal with bash argument parsing again!
You can view an updated script here
This has been enormously useful over the last year. It can now simulate scope by prefixing the variables with a scope parameter.
Just call the script like
replace() (
source $FUTIL_REL_DIR/commandParser.sh -scope ${FUNCNAME[0]} "$@"
echo ${replaceFlags[f]}
echo ${replaceBooleans[b]}
)
Doesn't look like I implemented argument scope, not sure why I guess I haven't needed it yet.

The problem is that there is no app installed to handle opening the PDF. You should use the Intent Chooser, like so:
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +"/"+ filename);
Intent target = new Intent(Intent.ACTION_VIEW);
target.setDataAndType(Uri.fromFile(file),"application/pdf");
target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
Intent intent = Intent.createChooser(target, "Open File");
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
// Instruct the user to install a PDF reader here, or something
}
you can use winhttprequest object instead of internet explorer as it's good to load data excluding pictures n advertisement instead of downloading full webpage including advertisement n pictures those make internet explorer object heavy compare to winhttpRequest object.
Check your decklaration on site. To load the Google Maps JavaScript API, use a script tag like this
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap"

I using this declaration on my Wordpress site in function.php file
wp_enqueue_script("google-maps-v3", "//maps.google.com/maps/api/js?key=YOUR_API_KEY", false, array(), false, true);
I have set API key on this format, and its works fine

I have not found a work around to have this work in other browsers.
EDIT: The only other way you can do this is to use box-shadow, but then this wont work if you already have a box shadow on that element.
I use this to clean up all files ending in ".orig":
function git-clean-orig {
git status -su | grep -e"\.orig$" | cut -f2 -d" " | xargs rm -r
}
If you are a scaredy-cat :) you could leave the last part off just to list them (or leave off the -r
if you want to approve each delete):
function git-show-orig {
git status -su | grep -e"\.orig$" | cut -f2 -d" "
}
I was able to get the original bundle identifier to work on my paid team membership account (after having it assigned to my personal team) by revoking the personal team signing certificate that was assigned to the same account id.
This won't work if you still need the certificate for other apps.

table to ensure you generate a row for every person, whether they have fears or not.Person_Fear
to every person, which will just be NULL

__init__
is required to return None. You cannot (or at least shouldn't) return something else.
Try making whatever you want to return an instance variable (or function).
>>> class Foo:
... def __init__(self):
... return 42
...
>>> foo = Foo()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: __init__() should return None
You can use formControlName
only on directives which implement ControlValueAccessor
.
So, in order to do what you want, you have to create a component which implements ControlValueAccessor
, which means implementing the following three functions:
writeValue
(tells Angular how to write value from model into view)registerOnChange
(registers a handler function that is called when the view changes)registerOnTouched
(registers a handler to be called when the component receives a touch event, useful for knowing if the component has been focused).Then, you have to tell Angular that this directive is a ControlValueAccessor
(interface is not gonna cut it since it is stripped from the code when TypeScript is compiled to JavaScript). You do this by registering a provider.
The provider should provide NG_VALUE_ACCESSOR
and use an existing value. You'll also need a forwardRef
here. Note that NG_VALUE_ACCESSOR
should be a multi provider.
For example, if your custom directive is named MyControlComponent, you should add something along the following lines inside the object passed to @Component
decorator:
providers: [
{
provide: NG_VALUE_ACCESSOR,
multi: true,
useExisting: forwardRef(() => MyControlComponent),
}
]
Your component is ready to be used. With template-driven forms, ngModel
binding will now work properly.
With reactive forms, you can now properly use formControlName
and the form control will behave as expected.
On version 4.4.1, you can use:
npm config set @myco:registry=http://reg.example.com
Where @myco is your package scope. You can install package in this way:
npm install @myco/my-package
var objDiv = document.getElementById("divExample");
objDiv.scrollTop = objDiv.scrollHeight;
In my case I needed to create a new folder in the www
directory called scripts
. Within scripts
I added a new file called test.py
.
I then used sudo chown www-data:root scripts
and sudo chown www-data:root test.py
.
Then I went to the new scripts
directory and used sudo chmod +x test.py
.
My test.py file it looks like this. Note the different Python version:
#!/usr/bin/env python3.5
print("Hello World!")
From php I now do this:
$message = exec("/var/www/scripts/test.py 2>&1");
print_r($message);
And you should see: Hello World!
I usually use BOOST_FOREACH:
#include <boost/foreach.hpp>
BOOST_FOREACH( vector_type::value_type& value, v ) {
// do something with 'value'
}
It works on STL containers, arrays, C-style strings, etc.
Note: Recent npm
versions do this automatically when package-locks are enabled, so this is not necessary except for removing development packages with the --production
flag.
Run npm prune
to remove modules not listed in package.json
.
From npm help prune
:
This command removes "extraneous" packages. If a package name is provided, then only packages matching one of the supplied names are removed.
Extraneous packages are packages that are not listed on the parent package's dependencies list.
If the
--production
flag is specified, this command will remove the packages specified in your devDependencies.

System.out.println("Result - status ("+ response.getStatusCode() + ") has body: " + response.hasBody());
}
catch (Exception eek) {
System.out.println("** Exception: "+ eek.getMessage());

The accepted answer didn't work for me inside the content script of a Firefox 6.0 Extension (Addon-SDK 1.0): Firefox executes the content script in each: the top-level window and in all iframes.
Inside the content script I get the following results:
(window !== window.top) : false
(window.self !== window.top) : true
The strange thing about this output is that it's always the same regardless whether the code is run inside an iframe or the top-level window.
On the other hand Google Chrome seems to execute my content script only once within the top-level window, so the above wouldn't work at all.
What finally worked for me in a content script in both browsers is this:
console.log(window.frames.length + ':' + parent.frames.length);
Without iframes this prints 0:0
, in a top-level window containing one frame it prints 1:1
, and in the only iframe of a document it prints 0:1
.
This allows my extension to determine in both browsers if there are any iframes present, and additionally in Firefox if it is run inside one of the iframes.
I would approach it like this:
sizes = [100, 250] print "How much space should the random song list occupy?" print '\n'.join("{0}. {1}Mb".format(n, s) for n, s in enumerate(sizes, 1)) # present choices choice = int(raw_input("Enter choice:")) # throws error if not int size = sizes[0] # safe starting choice if choice in range(2, len(sizes) + 1): size = sizes[choice - 1] # note index offset from choice print "You want to create a random song list that is {0}Mb.".format(size)
You could also loop until you get an acceptable answer and cover yourself in case of error:
choice = 0 while choice not in range(1, len(sizes) + 1): # loop try: # guard against error choice = int(raw_input(...)) except ValueError: # couldn't make an int print "Please enter a number" choice = 0 size = sizes[choice - 1] # now definitely valid
Possible duplicate: Is there a maven 2 archetype for spring 3 MVC applications?
That said, I would encourage you to think about making your own archetype. The reason is, no matter what you end up getting from someone else's, you can do better in not that much time, and a decent sized Java project is going to end up making a lot of jar projects.
Was looking at how to trust a certificate while using jenkins cli, and found https://issues.jenkins-ci.org/browse/JENKINS-12629 which has some recipe for that.
This will give you the certificate:
openssl s_client -connect ${HOST}:${PORT} </dev/null
if you are interested only in the certificate part, cut it out by piping it to:
| sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'
and redirect to a file:
> ${HOST}.cert
Then import it using keytool:
keytool -import -noprompt -trustcacerts -alias ${HOST} -file ${HOST}.cert \
-keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS}
In one go:
HOST=myhost.example.com
PORT=443
KEYSTOREFILE=dest_keystore
KEYSTOREPASS=changeme
# get the SSL certificate
openssl s_client -connect ${HOST}:${PORT} </dev/null \
| sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ${HOST}.cert
# create a keystore and import certificate
keytool -import -noprompt -trustcacerts \
-alias ${HOST} -file ${HOST}.cert \
-keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS}
# verify we've got it.
keytool -list -v -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS} -alias ${HOST}
as an alternative syntax you can write foreach loops like so
foreach($arr as $item):
//do stuff
endforeach;
This type of syntax is typically used when php is being used as a templating language as such
<?php foreach($arr as $item):?>
<!--do stuff -->
<?php endforeach; ?>
I was working with an unbound box for a simple project I was working on, so I couldn't use the standard binding approach. Consequently I created a simple hack that others might find quite handy by simply extending the existing TextBox control:
namespace MyApplication.InterfaceSupport
{
public class NumericTextBox : TextBox
{
public NumericTextBox() : base()
{
TextChanged += OnTextChanged;
}
public void OnTextChanged(object sender, TextChangedEventArgs changed)
{
if (!String.IsNullOrWhiteSpace(Text))
{
try
{
int value = Convert.ToInt32(Text);
}
catch (Exception e)
{
MessageBox.Show(String.Format("{0} only accepts numeric input.", Name));
Text = "";
}
}
}
public int? Value
{
set
{
if (value != null)
{
this.Text = value.ToString();
}
else
Text = "";
}
get
{
try
{
return Convert.ToInt32(this.Text);
}
catch (Exception ef)
{
// Not numeric.
}
return null;
}
}
}
}
Obviously, for a floating type, you would want to parse it as a float and so on. The same principles apply.
Then in the XAML file you need to include the relevant namespace:
<UserControl x:Class="MyApplication.UserControls.UnParameterisedControl"
[ Snip ]
xmlns:interfaceSupport="clr-namespace:MyApplication.InterfaceSupport"
>
After that you can use it as a regular control:
<interfaceSupport:NumericTextBox Height="23" HorizontalAlignment="Left" Margin="168,51,0,0" x:Name="NumericBox" VerticalAlignment="Top" Width="120" >
You need to set ulimit -c
. If you have 0 for this parameter a coredump file is not created. So do this: ulimit -c unlimited
and check if everything is correct ulimit -a
. The coredump file is created when an application has done for example something inappropriate. The name of the file on my system is core.<process-pid-here>
.
I found several posts telling me to run several gpg commands, but they didn't solve the problem because of two things. First, I was missing the debian-keyring package on my system and second I was using an invalid keyserver. Try different keyservers if you're getting timeouts!
Thus, the way I fixed it was:
apt-get install debian-keyring
gpg --keyserver pgp.mit.edu --recv-keys 1F41B907
gpg --armor --export 1F41B907 | apt-key add -
Then running a new "apt-get update" worked flawlessly!
The easiest way is to redirect the output of the echo
by >>
:
echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile
in my case, i cannot clone github due to user is wrong.
go to ~/.gitconfig
then try to remove this line of code (just delete it then save file).
[user]
name = youruser
email = [email protected]
or try to use one liner in your cmd or terminal : git config --global --remove-section user
and try to do git clone again. hope it'll fix your day. ><
Its 2020 and lots of you will come here looking for a similar solution but with Hooks ( They are great! ) and with latest approaches in terms of code cleanliness and syntax.
So as previous answers had stated, the best approach to this kind of problem is to hold the state outside of child component fieldEditor
.
You could do that in multiple ways.
The most "complex" is with global context (state) that both parent and children could access and modify. Its a great solution when components are very deep in the tree hierarchy and so its costly to send props in each level.
In this case I think its not worth it, and more simple approach will bring us the results we want, just using the powerful React.useState()
.
As said we will deal with changes and store the data of our child component fieldEditor
in our parent fieldForm
. To do that
we will send a reference to the function that will deal and apply the changes to the fieldForm
state, you could do that with:
function FieldForm({ fields }) {
const [fieldsValues, setFieldsValues] = React.useState({});
const handleChange = (event, fieldId) => {
let newFields = { ...fieldsValues };
newFields[fieldId] = event.target.value;
setFieldsValues(newFields);
};
return (
<div>
{fields.map(field => (
<FieldEditor
key={field}
id={field}
handleChange={handleChange}
value={fieldsValues[field]}
/>
))}
<div>{JSON.stringify(fieldsValues)}</div>
</div>
);
}
Note that React.useState({})
will return an array with position 0 being the value specified on call (Empty object in this case), and position 1 being the reference to the function
that modifies the value.
Now with the child component, FieldEditor
, you don't even need to create a function with a return statement, a lean constant with an arrow function
will do!
const FieldEditor = ({ id, value, handleChange }) => (
<div className="field-editor">
<input onChange={event => handleChange(event, id)} value={value} />
</div>
);
Aaaaand we are done, nothing more, with just these two slime functional components we have our end goal "access" our child FieldEditor
value and show it off in our parent.
You could check the accepted answer from 5 years ago and see how Hooks made React code leaner (By a lot!).
Hope my answer helps you learn and understand more about Hooks, and if you want to check a working example here it is.
Each answer is missing some points, so here is my solution:
$("#input").on("input", function(e) {_x000D_
var input = $(this);_x000D_
var val = input.val();_x000D_
_x000D_
if (input.data("lastval") != val) {_x000D_
input.data("lastval", val);_x000D_
_x000D_
//your change action goes here _x000D_
console.log(val);_x000D_
}_x000D_
_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="text" id="input">_x000D_
<p>Try to drag the letters and copy paste</p>
_x000D_
The Input Event
fires on Keyboard input, Mouse Drag, Autofill and Copy-Paste tested on Chrome and Firefox.
Checking for previous value makes it detect real changes, which means not firing when pasting the same thing or typing the same character or etc.
Working example: http://jsfiddle.net/g6pcp/473/
update:
And if you like to run your change function
only when user finishes typing and prevent firing the change action several times, you could try this:
var timerid;_x000D_
$("#input").on("input", function(e) {_x000D_
var value = $(this).val();_x000D_
if ($(this).data("lastval") != value) {_x000D_
_x000D_
$(this).data("lastval", value);_x000D_
clearTimeout(timerid);_x000D_
_x000D_
timerid = setTimeout(function() {_x000D_
//your change action goes here _x000D_
console.log(value);_x000D_
}, 500);_x000D_
};_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="text" id="input">
_x000D_
If user starts typing (e.g. "foobar") this code prevents your change action
to run for every letter user types and and only runs when user stops typing, This is good specially for when you send the input to the server (e.g. search inputs), that way server does only one search for foobar
and not six searches for f
and then fo
and then foo
and foob
and so on.
Because that syntax simply isn't defined? Besides, x < y
evaluates as a bool, so what does bool < int
mean? It isn't really an overhead; besides, you could write a utility method if you really want - isBetween(10,x,20)
- I wouldn't myself, but hey...
None of the above solutions worked for me, I had to use .then
swal({
title: 'Success!',
text: message,
type: 'success',
confirmButtonText: 'OK'
}).then(() => {
console.log('triggered redirect here');
});
Here's some examples of how I use strace to dig into websites. Hope this is helpful.
Check for time to first byte like so:
time php index.php > timeTrace.txt
See what percentage of actions are doing what. Lots of lstat
and fstat
could be an indication that it's time to clear the cache:
strace -s 200 -c php index.php > traceLstat.txt
Outputs a trace.txt
so you can see exactly what calls are being made.
strace -Tt -o Fulltrace.txt php index.php
Use this to check on whether anything took between .1
to .9
of a second to load:
cat Fulltrace.txt | grep "[<]0.[1-9]" > traceSlowest.txt
See what missing files or directories got caught in the strace
. This will output a lot of stuff involving our system - the only relevant bits involve the customer's files:
strace -vv php index.php 2>&1 | sed -n '/= -1/p' > traceFailures.txt
Application is not the same as the Singleton.The reasons are:
This simple static function calculates the fraction of months between two Datetimes, e.g.
The function assumes that the first date is smaller than the second date. To deal with negative time intervals one can modify the function easily by introducing a sign and a variable swap at the beginning.
public static double GetDeltaMonths(DateTime t0, DateTime t1)
{
DateTime t = t0;
double months = 0;
while(t<=t1)
{
int daysInMonth = DateTime.DaysInMonth(t.Year, t.Month);
DateTime endOfMonth = new DateTime(t.Year, t.Month, daysInMonth);
int cutDay = endOfMonth <= t1 ? daysInMonth : t1.Day;
months += (cutDay - t.Day + 1) / (double) daysInMonth;
t = new DateTime(t.Year, t.Month, 1).AddMonths(1);
}
return Math.Round(months,2);
}
Here, I will show you 2 different implementation:
First:
If you just need to create a duplicate table then just run the command:
SELECT top 0 * INTO [dbo].[DuplicateTable]
FROM [dbo].[MainTable]
Of course, it doesn't work completely. constraints don't get copied, nor do primary keys, or default values. The command only creates a new table with the same column structure and if you want to insert data into the new table.
Second (recommended):
But If you want to duplicate the table with all its constraints & keys follows this below steps:
You can use like this:
@Transactional(propagation = Propagation.REQUIRES_NEW)
public EventMessage<ModificaOperativitaRapporto> activate(EventMessage<ModificaOperativitaRapporto> eventMessage) {
//here some transaction related code
}
You can use this thing also:
public interface TransactionStatus extends SavepointManager {
boolean isNewTransaction();
boolean hasSavepoint();
void setRollbackOnly();
boolean isRollbackOnly();
void flush();
boolean isCompleted();
}
Position your <div>
absolutely at the bottom and don't forget to give div.A
a position: relative
- http://jsfiddle.net/TTaMx/
.A {
position: relative;
margin: 40px 0;
height: 40px;
width: 200px;
background: #eee;
}
.A:after {
content: " ";
display: block;
background: #c00;
height: 29px;
width: 100%;
position: absolute;
bottom: -29px;
}?
You can use the build in CLLocationDistance to calculate this:
CLLocation *location1 = [[CLLocation alloc] initWithLatitude:latitude1 longitude:longitude1];
CLLocation *location2 = [[CLLocation alloc] initWithLatitude:latitude2 longitude:longitude2];
[self distanceInMetersFromLocation:location1 toLocation:location2]
- (int)distanceInMetersFromLocation:(CLLocation*)location1 toLocation:(CLLocation*)location2 {
CLLocationDistance distanceInMeters = [location1 distanceFromLocation:location2];
return distanceInMeters;
}
In your case if you want kilometers just divide by 1000.
From Bash Guide section on globbing
To use an extglob in a parameter expansion
#Turn on extended globbing
shopt -s extglob
#Trim leading and trailing whitespace from a variable
x=${x##+([[:space:]])}; x=${x%%+([[:space:]])}
#Turn off extended globbing
shopt -u extglob
Here's the same functionality wrapped in a function (NOTE: Need to quote input string passed to function):
trim() {
# Determine if 'extglob' is currently on.
local extglobWasOff=1
shopt extglob >/dev/null && extglobWasOff=0
(( extglobWasOff )) && shopt -s extglob # Turn 'extglob' on, if currently turned off.
# Trim leading and trailing whitespace
local var=$1
var=${var##+([[:space:]])}
var=${var%%+([[:space:]])}
(( extglobWasOff )) && shopt -u extglob # If 'extglob' was off before, turn it back off.
echo -n "$var" # Output trimmed string.
}
Usage:
string=" abc def ghi ";
#need to quote input-string to preserve internal white-space if any
trimmed=$(trim "$string");
echo "$trimmed";
If we alter the function to execute in a subshell, we don't have to worry about examining the current shell option for extglob, we can just set it without affecting the current shell. This simplifies the function tremendously. I also update the positional parameters "in place" so I don't even need a local variable
trim() {
shopt -s extglob
set -- "${1##+([[:space:]])}"
printf "%s" "${1%%+([[:space:]])}"
}
so:
$ s=$'\t\n \r\tfoo '
$ shopt -u extglob
$ shopt extglob
extglob off
$ printf ">%q<\n" "$s" "$(trim "$s")"
>$'\t\n \r\tfoo '<
>foo<
$ shopt extglob
extglob off
/html/body/table/tbody/tr[9]/td[1]
In Chrome (possible Safari too) you can inspect an element, then right click on the tag you want to get the xpath for, then you can copy the xpath to select that element.
In addition to other answers, you can write an extension for Date class to get formatted Data in specific TimeZone to make it as utility function for future use. Like
extension Date {
func dateInTimeZone(timeZoneIdentifier: String, dateFormat: String) -> String {
let dtf = DateFormatter()
dtf.timeZone = TimeZone(identifier: timeZoneIdentifier)
dtf.dateFormat = dateFormat
return dtf.string(from: self)
}
}
Now you can call it like
Date().dateInTimeZone(timeZoneIdentifier: "UTC", dateFormat: "yyyy-MM-dd HH:mm:ss");
I came across this issue recently. I used PuPHPet to generate a config.

First of all, don't use different encodings. It leads to a mess, and UTF-8 is definitely the one you should be using everywhere.
Chances are your input is not ISO-8859-1, but something else (ISO-8859-15, Windows-1252). To convert from those, use iconv or mb_convert_encoding
.
Nevertheless, utf8_encode
and utf8_decode
should work for ISO-8859-1. It would be nice if you could post a link to a file or a uuencoded or base64 example string for which the conversion fails or yields unexpected results.
You cannot upload like this.
http://grand-shopping.com/<"some folder">
You need a physical path exactly like in your local
C:/Users/puneet verma/Downloads/
What you can do is create some local path where your server is working. Hence you can store and retrieve the file. If you bought some domain from any websites there will be path to upload the files. You create these variable as static constant and use it based on the server you are working (Local/Website).

Have a look at the example in this link :
http://docs.angularjs.org/api/ngSanitize.$sanitize
Basically, angular has a directive to insert html into pages. In your case you can insert the html using the ng-bind-html directive like so :
If you already have done all this :
// My magic HTML string function.
function htmlString (str) {
return "<h1>" + str + "</h1>";
}
function Ctrl ($scope) {
var str = "HELLO!";
$scope.htmlString = htmlString(str);
}
Ctrl.$inject = ["$scope"];
Then in your html within the scope of that controller, you could
<div ng-bind-html="htmlString"></div>
Steps (1) Just Select your range, rows or column or array , (2) Press ctrl+H , (3 a) then in the find type a space (3 b) in the replace do not enter anything, (4)then just click on replace all..... you are done.
I think what you want to achieve is with the collaboration of "@mouseover and @mouseleave" or "@mouseenter and @mouseleave"
And I think, It's better to use the 2nd pair so that you can achieve the hover effect and call functionlaities on that.
<div @mouseenter="activeHover = true" @mouseleave="activeHover = false" >
<p v-if="activeHover"> This will be showed on hover </p>
<p v-if ="!activeHover"> This will be showed in simple cases </p>
</div>
on vue instance
data : {
activeHover : false
}
I hope, it will help others as well :)
I extends a TreeMap and override entrySet() and values() methods. Key and value need to be Comparable.
Follow the code:

Set<Entry<K, V>> originalEntries = super.entrySet();
Set<Entry<K, V>> sortedEntry = new TreeSet<Entry<K, V>>(new Comparator<Entry<K, V>>() {
@Override
public int compare(Entry<K, V> entryA, Entry<K, V> entryB) {
int compareTo = entryA.getValue().compareTo(entryB.getValue());
if(compareTo == 0) {
compareTo = entryA.getKey().compareTo(entryB.getKey());
}
return compareTo;
}
});
sortedEntry.addAll(originalEntries);
return sortedEntry;
}
@Override
public Collection<V> values() {
Set<V> sortedValues = new TreeSet<>(new Comparator<V>(){
@Override

Delete
operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirementsInsert
for arrays is basically Set
as mentioned in the beginningThis might be somewhat of a hack, but it got the job done in our case:
(0 || myfield)::integer
Explanation (Tested on Postgres 8.4):
The above mentioned expression yields NULL
for NULL-values in myfield
and 0
for empty strings (This exact behaviour may or may not fit your use case).
SELECT id, (0 || values)::integer from test_table ORDER BY id
Test data:
CREATE TABLE test_table
(
id integer NOT NULL,
description character varying,
"values" character varying,
CONSTRAINT id PRIMARY KEY (id)
)
-- Insert Test Data
INSERT INTO test_table VALUES (1, 'null', NULL);
INSERT INTO test_table VALUES (2, 'empty string', '');
INSERT INTO test_table VALUES (3, 'one', '1');
The query will yield the following result:
---------------------
|1|null |NULL|
|2|empty string|0 |
|3|one |1 |
---------------------
Whereas select only values::integer
will result in an error message.
Hope this helps.
Those are zero-length strings, not null. But if you want to remove them:
firstArray[0] refers to the first element
firstArray[1] refers to the second element
You can move the second into the first thusly:
firstArray[0] = firstArray[1]
If you were to do this for elements [1,2], then [2,3], etc. you would eventually shift the entire contents of the array to the left, eliminating element 0. Can you see how that would apply?
You could do like this:
SELECT city FROM user WHERE (firstName, lastName) IN (('a', 'b'), ('c', 'd'));
Yes if you are using Python 3.3+. You can use the built-in unittest.mock
to assert method called. For Python 2.6+ use the rolling backport Mock
, which is the same thing.
Here is a quick example in your case:
from unittest.mock import MagicMock
aw = aps.Request("nv1")
aw.Clear = MagicMock()
aw2 = aps.Request("nv2", aw)
assert aw.Clear.called
Quote from Jeff Handley's Blog Post on Validation Objects and Properties with Validator:
When validating an object, the following process is applied in Validator.ValidateObject:
- Validate property-level attributes
- If any validators are invalid, abort validation returning the failure(s)
- Validate the object-level attributes
- If any validators are invalid, abort validation returning the failure(s)
- If on the desktop framework and the object implements IValidatableObject, then call its Validate method and return any failure(s)
This indicates that what you are attempting to do won't work out-of-the-box because the validation will abort at step #2. You could try to create attributes that inherit from the built-in ones and specifically check for the presence of an enabled property (via an interface) before performing their normal validation. Alternatively, you could put all of the logic for validating the entity in the Validate
method.
You also could take a look a the exact implemenation of Validator
class here
Definitely regex:
string CleanPhone(string phone)
{
Regex digitsOnly = new Regex(@"[^\d]");
return digitsOnly.Replace(phone, "");
}
or within a class to avoid re-creating the regex all the time:
private static Regex digitsOnly = new Regex(@"[^\d]");
public static string CleanPhone(string phone)
{
return digitsOnly.Replace(phone, "");
}
Depending on your real-world inputs, you may want some additional logic there to do things like strip out leading 1's (for long distance) or anything trailing an x or X (for extensions).

array_of_pointers[4][1] = &m;
//Get position 4 of array, then get position 1, then put m ptr in there.
printf("%c", *array_of_pointers[4][1]);
//Get position 4 of array, then get position 1 and dereference it.
How to create a pointer to an 2D array of characters:
char (*pointer_to_array)[5][2];
//A pointer to an array size 5 each containing arrays size 2 which hold chars
char m = 'm';
//character value holding the value 'm'
(*pointer_to_array)[4][1] = m;
//dereference array, Get position 4, get position 1, put m there.
printf("%c", (*pointer_to_array)[4][1]);
//dereference array, Get position 4, get position 1

Swift 5 : If you continuously want input from keyboard , without ending the program, like a stream of input, Use below steps:
Create new project of type comnnad line tool
Add below code in main.swift file:
var inputArray = [String]()
while let input = readLine() {
guard input != "quit" else {
break
}
inputArray.append(input)
print("You entered: \(input)")
print(inputArray)
print("Enter a word:")
}
Just use the location.host property
switch (location.host) {
case "xxx.local":
settings = ...
break;
case "xxx.dev.yyy.com":
settings = ...
break;
}
Check the local.properties file in your Studio Project. Chances are that the property sdk.dir points to the wrong folder if you had set/configured a previous android sdk from pre-studio era. This was the solution in my case.
save.patch
file to wherever (including binary files).git apply <file>
Note: it diff's the currently staged files too.
$ git diff --binary --staged HEAD > save.patch
$ git reset --hard
$ <transport it>
$ git apply save.patch
Here's an example if:

i have same problem and i think just set width and height programmatically :
set width of button's with metrics.widthPixels / 2 metrics is object of DisplayMetrics.
GridLayout gridLayout=findViewById(R.id.grid);
for (int i = 0; i <gridLayout.getChildCount() ; i++) {
View view= gridLayout.getChildAt(i);
if(view instanceof Button){
Button btn = (Button) view;
btn.setWidth(200);//metrics.widthPixels / 2
btn.setHeight(200);//metrics.heightPixels / 7
}
}
If you want to know the port number of your local host on which Mysql is running you can use this query on MySQL Command line client --
SHOW VARIABLES WHERE Variable_name = 'port';
mysql> SHOW VARIABLES WHERE Variable_name = 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port | 3306 |
+---------------+-------+
1 row in set (0.00 sec)
It will give you the port number on which MySQL is running.
If you want to know the hostname of your Mysql you can use this query on MySQL Command line client --
SHOW VARIABLES WHERE Variable_name = 'hostname';
mysql> SHOW VARIABLES WHERE Variable_name = 'hostname';
+-------------------+-------+
| Variable_name | Value |
+-------------------+-------+
| hostname | Dell |
+-------------------+-------+
1 row in set (0.00 sec)
It will give you the hostname for mysql.
If you want to know the username of your Mysql you can use this query on MySQL Command line client --
select user();
mysql> select user();
+----------------+
| user() |
+----------------+
| root@localhost |
+----------------+
1 row in set (0.00 sec)
It will give you the username for mysql.
in flask, with babel, I like to do this :
@app.template_filter('dt')
def _jinja2_filter_datetime(date, fmt=None):
if fmt:
return date.strftime(fmt)
else:
return date.strftime(gettext('%%m/%%d/%%Y'))
used in the template with {{mydatetimeobject|dt}}
so no with babel you can specify your various format in messages.po like this for instance :
#: app/views.py:36
#, python-format
msgid "%%m/%%d/%%Y"
msgstr "%%d/%%m/%%Y"
Also can be done from the environment variable:
export CURL_CA_BUNDLE=""
Simple CASE expression:
CASE input_expression
WHEN when_expression THEN result_expression [ ...n ]
[ ELSE else_result_expression ]
END
Searched CASE expression:

WHEN Boolean_expression THEN result_expression [ ...n ]
[ ELSE else_result_expression ]
END

Below is the link which guide in parsing JSON string in android.
http://www.ibm.com/developerworks/xml/library/x-andbene1/?S_TACT=105AGY82&S_CMP=MAVE
Also according to your json string code snippet must be something like this:-
JSONObject mainObject = new JSONObject(yourstring);
JSONObject universityObject = mainObject.getJSONObject("university");
JSONString name = universityObject.getString("name");
JSONString url = universityObject.getString("url");
Following is the API reference for JSOnObject: https://developer.android.com/reference/org/json/JSONObject.html#getString(java.lang.String)
Same for other object.
s=s.replaceAll("[*a-zA-Z]", "")
replaces all alphabets
s=s.replaceAll("[*0-9]", "")
replaces all numerics
if you do above two replaces you will get all special charactered string
If you want to extract only integers from a String s=s.replaceAll("[^0-9]", "")
If you want to extract only Alphabets from a String s=s.replaceAll("[^a-zA-Z]", "")
Happy coding :)
I am a beginner tinkering on somebody else's code so please be lenient and further correct my errors. I tried your code and played with the VBA help The following worked with me:
Function currAddressTest(dataRangeTest As Range) As String
currAddressTest = ActiveSheet.Name & "$" & dataRangeTest.Address(False, False)
End Function
When I select data source argument for my function, it is turned into Sheet1$A1:G3 format. If excel changes it to Table1[#All] reference in my formula, the function still works properly
I then used it in your function (tried to play and add another argument to be injected to WHERE...
Function SQL(dataRange As Range, CritA As String)
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim currAddress As String
currAddress = ActiveSheet.Name & "$" & dataRange.Address(False, False)
strFile = ThisWorkbook.FullName
strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & strFile _
& ";Extended Properties=""Excel 12.0;HDR=Yes;IMEX=1"";"
Set cn = CreateObject("ADODB.Connection")
Set rs = CreateObject("ADODB.Recordset")
cn.Open strCon
strSQL = "SELECT * FROM [" & currAddress & "]" & _
"WHERE [A] = '" & CritA & "' " & _
"ORDER BY 1 ASC"
rs.Open strSQL, cn
SQL = rs.GetString
End Function
Hope your function develops further, I find it very useful. Have a nice day!
No need for regex. os.path.splitext
is your friend:
os.path.splitext('1.1.1.jpg')
>>> ('1.1.1', '.jpg')
The key system must have several properties:
One solution that should give you these would be to use a public key signing scheme. Start with a "system hash" (say grab the macs on any NICs, sorted, and the CPU-ID info, plus some other stuff, concatenate it all together and take an MD5 of the result (you really don't want to be handling personally identifiable information if you don't have to)) append the CD's serial number and refuse to boot unless some registry key (or some datafile) has a valid signature for the blob. The user activates the program by shipping the blob to you and you ship back the signature.
Potential issues include that you are offering to sign practically anything so you need to assume someone will run a chosen plain text and/or chosen ciphertext attacks. That can be mitigated by checking the serial number provided and refusing to handle request from invalid ones as well as refusing to handle more than a given number of queries from a given s/n in an interval (say 2 per year)
I should point out a few things: First, a skilled and determined attacker will be able to bypass any and all security in the parts that they have unrestricted access to (i.e. everything on the CD), the best you can do on that account is make it harder to get illegitimate access than it is to get legitimate access. Second, I'm no expert so there could be serious flaws in this proposed scheme.
Another recursive approach:
# change directory to target folder:
cd /Volumes/path/to/folder
# find all things of type "f" (file),
# then pipe "|" each result as an argument (xargs -0)
# to the "xattr -c" command:
find . -type f -print0 | xargs -0 xattr -c
# Sometimes you may have to use a star * instead of the dot.
# The dot just means "here" (whereever your cd'd to
find * -type f -print0 | xargs -0 xattr -c
In mysql the SET
clause needs to come after the JOIN
. Example:
UPDATE e
LEFT JOIN a ON a.id = e.aid
SET e.id = 2
WHERE
e.type = 'user' AND
a.country = 'US';
To get the cell value, you need to read it directly from DataGridView1
using e.RowIndex
and e.ColumnIndex
properties.
Eg:
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim value As Object = DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value
If IsDBNull(value) Then
TextBox1.Text = "" ' blank if dbnull values
Else
TextBox1.Text = CType(value, String)
End If
End Sub
I happen all the time when you install a new plugin. You just have to delete maintenance.flag file in your root directory
PHP and references are somewhat unintuitive. If used appropriately references in the right places can provide large performance improvements or avoid very ugly workarounds and unusual code.
The following will produce an error:
function f(&$v){$v = true;}
f(&$v);
function f($v){$v = true;}
f(&$v);
None of these have to fail as they could follow the rules below but have no doubt been removed or disabled to prevent a lot of legacy confusion.
If they did work, both involve a redundant conversion to reference and the second also involves a redundant conversion back to a scoped contained variable.
The second one used to be possible allowing a reference to be passed to code that wasn't intended to work with references. This is extremely ugly for maintainability.
This will do nothing:
function f($v){$v = true;}
$r = &$v;
f($r);
More specifically, it turns the reference back into a normal variable as you have not asked for a reference.
This will work:
function f(&$v){$v = true;}
f($v);
This sees that you are passing a non-reference but want a reference so turns it into a reference.
What this means is that you can't pass a reference to a function where a reference is not explicitly asked for making it one of the few areas where PHP is strict on passing types or in this case more of a meta type.
If you need more dynamic behaviour this will work:
function f(&$v){$v = true;}
$v = array(false,false,false);
$r = &$v[1];
f($r);
Here it sees that you want a reference and already have a reference so leaves it alone. It may also chain the reference but I doubt this.
To make it simpler
SELECT *,MIN(price) FROM prod LIMIT 1
Just to add the information I was looking for: pragma mark
is Xcode specific, so if you deal with a C++ project that you open in different IDEs, it does not have any effect there. In Qt Creator, for example, it does not add categories for methods, nor generate any warnings/errors.
EDIT
#pragma
is a preprocessor directive which comes from C programming language. Its purpose is to specify implementation-dependent information to the compiler - that is, each compiler might choose to interpret this directive as it wants. That said, it is rather considered an extension which does not change/influence the code itself. So compilers might as well ignore it.
Xcode is an IDE which takes advantage of #pragma
and uses it in its own specific way. The point is, #pragma
is not Xcode and even Objective-C specific.
Try
loadUrl(String url, Map<String, String> extraHeaders)
For adding headers to resources loading requests, make custom WebViewClient and override:
API 24+:
WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request)
or
WebResourceResponse shouldInterceptRequest(WebView view, String url)
For those situations where width of the items you do want to flex-end
is known, you can set their flex to "0 0 ##px" and set the item you want to flex-start
with flex:1
This will cause the pseudo flex-start
item to fill the container, just format it to text-align:left
or whatever.
maybe I'd go by this.
SQL = SELECT REPLACE(myColumn, '""', '\'') FROM myTable
I used singlequotes because that's the one that registers string expressions in MySQL, or so I believe.
Hope that helps.
In my case,
myButton.setEnabled(false);
myButton.setEnabled(true);
is working fine and it is enabling and disabling the button as it should. But once the button state becomes disabled, it never goes back to the enabled state again, although it's clickable. I tried invalidating and refreshing the drawable state, but no luck.
myButton.invalidate();
myButton.refreshDrawableState();
If you or anyone having a similar issue, what works for me is setting the background drawable again. Works on any API Level.
myButton.setEnabled(true);
myButton.setBackgroundDrawable(activity.getResources().getDrawable(R.drawable.myButtonDrawable));
The problem is that your REGX pattern will only match the input "0-9".
To meet your requirement (0-9999999), you should rewrite your regx pattern:
ng-pattern="/^[0-9]{1,7}$/"
My example:
HTML:
<div ng-app ng-controller="formCtrl">
<form name="myForm" ng-submit="onSubmit()">
<input type="number" ng-model="price" name="price_field"
ng-pattern="/^[0-9]{1,7}$/" required>
<span ng-show="myForm.price_field.$error.pattern">Not a valid number!</span>
<span ng-show="myForm.price_field.$error.required">This field is required!</span>
<input type="submit" value="submit"/>
</form>
</div>
JS:
function formCtrl($scope){
$scope.onSubmit = function(){
alert("form submitted");
}
}
Here is a jsFiddle demo.
This is the official explanation from sonatype nexus team about 401 - Unauthorized
I recommend you to read Troubleshooting Artifact Deployment Failures for more information.
Code 401 - Unauthorized
Either no login credentials were sent with the request, or login credentials which are invalid were sent. Checking the "authorization and authentication" system feed in the Nexus UI can help narrow this down. If credentials were sent there will be an entry in the feed.
If no credentials were sent this is likely due to a mis-match between the id in your pom's distributionManagement section and your settings.xml's server section that holds the login credentials.
If your list got large enough and you only expected to find the value in a sparse number of indices, consider that this code could execute much faster because you don't have to iterate every value in the list.
lookingFor = 1
i = 0
index = 0
try:
while i < len(testlist):
index = testlist.index(lookingFor,i)
i = index + 1
print index
except ValueError: #testlist.index() cannot find lookingFor
pass
If you expect to find the value a lot you should probably just append "index" to a list and print the list at the end to save time per iteration.
I came here to remind myself how to code a second index into the increment clause of a FOR loop, which I knew could be done mainly from observing it in a sample that I incorporated into another project, that written in C++.
Today, I am working in C#, but I felt sure that it would obey the same rules in this regard, since the FOR statement is one of the oldest control structures in all of programming. Thankfully, I had recently spent several days precisely documenting the behavior of a FOR loop in one of my older C programs, and I quickly realized that those studies held lessons that applied to today's C# problem, in particular to the behavior of the second index variable.
For the unwary, following is a summary of my observations. Everything I saw happening today, by carefully observing variables in the Locals window, confirmed my expectation that a C# FOR statement behaves exactly like a C or C++ FOR statement.
If either of your index variables remains in scope when the loop ends, their value will be one higher than the threshold that stops the loop, in the case of the true index variable. Likewise, if, for example, the second variable is initialized to zero before the loop is entered, its value at the end will be the iteration count, assuming that it is an increment (++), not a decrement, and that nothing in the body of the loop changes its value.
A DLL uses the PE executable format, and it's not too tricky to read that information out of the file.
See this MSDN article on the PE File Format for an overview. You need to read the MS-DOS header, then read the IMAGE_NT_HEADERS structure. This contains the IMAGE_FILE_HEADER structure which contains the info you need in the Machine member which contains one of the following values
This information should be at a fixed offset in the file, but I'd still recommend traversing the file and checking the signature of the MS-DOS header and the IMAGE_NT_HEADERS to be sure you cope with any future changes.
You can also use the ImageHelp API to do this - load the DLL with LoadImage and you'll get a LOADED_IMAGE structure which will contain a pointer to an IMAGE_NT_HEADERS structure. Deallocate the LOADED_IMAGE with ImageUnload.
Here's rough Perl script which gets the job done. It checks the file has a DOS header, then reads the PE offset from the IMAGE_DOS_HEADER 60 bytes into the file.
It then seeks to the start of the PE part, reads the signature and checks it, and then extracts the value we're interested in.
#!/usr/bin/perl
#
# usage: petype <exefile>
#
$exe = $ARGV[0];
open(EXE, $exe) or die "can't open $exe: $!";
binmode(EXE);
if (read(EXE, $doshdr, 64)) {
($magic,$skip,$offset)=unpack('a2a58l', $doshdr);
die("Not an executable") if ($magic ne 'MZ');
seek(EXE,$offset,SEEK_SET);
if (read(EXE, $pehdr, 6)){
($sig,$skip,$machine)=unpack('a2a2v', $pehdr);
die("No a PE Executable") if ($sig ne 'PE');
if ($machine == 0x014c){
print "i386\n";
}
elsif ($machine == 0x0200){
print "IA64\n";
}

}
else{

}
}
}

For anyone interested to implement a DropDown
of custom class
you can follow the bellow steps.
Suppose you have a class called Language
with the following code and a static
method which returns a List<Language>
class Language {
final int id;
final String name;
final String languageCode;
const Language(this.id, this.name, this.languageCode);
}
const List<Language> getLanguages = <Language>[
Language(1, 'English', 'en'),
Language(2, '?????', 'fa'),
Language(3, '????', 'ps'),
];
Anywhere you want to implement a DropDown
you can import
the Language
class first use it as follow
DropdownButton(
underline: SizedBox(),
icon: Icon(
Icons.language,
color: Colors.white,
),
items: getLanguages.map((Language lang) {
return new DropdownMenuItem<String>(
value: lang.languageCode,
child: new Text(lang.name),
);
}).toList(),
onChanged: (val) {
print(val);
},
)
I haven't been using jquery for a while but you might be looking for this:
Don't need to use this method:
.map((res: Response) => res.json() );
Just use this simple method instead of the previous method. hopefully you'll get your result:
.map(res => res );
gravity: is used for simple views like textview, edittext etc.
layout_gravity: is used for current view only gravity in context of it's relative parent view like linear Layout or FrameLayout to make view in center or any other gravity of its parent.
If you're using Bootstrap 3, you can use the embed-responsive class and set the padding bottom as the height divided by the width plus a little extra for toolbars. For example, to display an 8.5 by 11 PDF, use 130% (11/8.5) plus a little extra (20%).
<div class='embed-responsive' style='padding-bottom:150%'>
<object data='URL.pdf' type='application/pdf' width='100%' height='100%'></object>
</div>
Here's the Bootstrap CSS:
.embed-responsive {
position: relative;
display: block;
height: 0;
padding: 0;
overflow: hidden;
}
The following will result in a comma separated list. Be sure to include a using statement for System.Linq
List<string> ls = new List<string>();
ls.Add("one");
ls.Add("two");
string type = ls.Aggregate((x,y) => x + "," + y);
will yield one,two
if you need a space after the comma, simply change the last line to string type = ls.Aggregate((x,y) => x + ", " + y);
You can set values from html like this. I don't think there is a direct solution from angular yet.
<div style="visibility: hidden;">{{activeTitle='home'}}</div>
echo str_pad("1234567", 8, '0', STR_PAD_LEFT);
This is working in IE 11 with Bootstrap 4.3. While the other answers were not working in IE11 in my case.
<div class="row mx-auto justify-content-center align-items-center flex-column ">
<div class="col-6">Something </div>
</div>
it works for me. if you want to enable future time for choose, you have to delete maximum date. You need to to do like followings.
btnDate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DialogFragment newFragment = new DatePickerFragment();
newFragment.show(getSupportFragmentManager(), "datePicker");
}
});
public static class DatePickerFragment extends DialogFragment
implements DatePickerDialog.OnDateSetListener {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, year, month, day);
dialog.getDatePicker().setMaxDate(c.getTimeInMillis());
return dialog;
}
public void onDateSet(DatePicker view, int year, int month, int day) {
btnDate.setText(ConverterDate.ConvertDate(year, month + 1, day));
}
}
Before update SDK components, check in Android SDK Manager ? Tools ? Options and set HTTP proxy and port if it is set in local LAN.
Or do this in more dynamic way
$(window).bind('scroll', function () {
var menu = $('.menu');
if ($(window).scrollTop() > menu.offset().top) {
menu.addClass('fixed');
} else {
menu.removeClass('fixed');
}
});
In CSS add class
.fixed {
position: fixed;
top: 0;
}
The simplest & the best solution:
mylist.OrderBy(s => s.GetType().GetProperty("PropertyName").GetValue(s));
Set variable "a" to some value like this,
a=0;
Declaring and initialzing are both different.
Good Luck
I liked the answer by Nick and was playing around with this solution. Found a cleaner method. Since ::before/::after pseudos don't work on replaced elements like img and object they will only work if the object data (src) is not loaded. It keeps the HTML more clean and will only add the pseudo if the object fails to load.

I think we can understand the difference between these two by seeing a Java8 example code:
interface Something{}
interface OneWhoCanProvideSomething {
Something getSomething();
}
interface OneWhoCanProvideCreatorsOfSomething{
OneWhoCanProvideSomething getCreator();
}
public class AbstractFactoryExample {
public static void main(String[] args) {
//I need something
//Let's create one
Something something = new Something() {};
//Or ask someone (FACTORY pattern)
OneWhoCanProvideSomething oneWhoCanProvideSomethingOfTypeA = () -> null;
OneWhoCanProvideSomething oneWhoCanProvideSomethingOfTypeB = () -> null;
//Or ask someone who knows soemone who can create something (ABSTRACT FACTORY pattern)
OneWhoCanProvideCreatorsOfSomething oneWhoCanProvideCreatorsOfSomething = () -> null;
//Same thing, but you don't need to write you own interfaces
Supplier<Something> supplierOfSomething = () -> null;
Supplier<Supplier<Something>> supplierOfSupplier = () -> null;
}
}
Now the question is which way of creation should you use and why: The first way (no pattern, just plain constructor): creating by yourself is not a good idea, you have to do all the work, and your client code is tied to the particular implementation.
The second way (using Factory pattern): provides you the benefit that you can pass any type of implementation, which can provide different type of something based on some condition (maybe a parameter passed to creational method).
The third way (using Abstract Factory pattern): This gives you more flexibility. You can find different types of creators of something based on some condition (maybe a parameter passed).
Note that you can always get away with Factory pattern by combining two conditions together (which slightly increases code complexity, and coupling), I guess that's why we rarely see real life use cases of Abstract Factory pattern.
To anyone using Windows and Windows Subsystem for Linux, make sure that when you run the python command from the command line, it's not accidentally running the python installation from WSL! This gave me quite a headache just now. A quick check you can do for this is just
which <python command you're using>
If that prints something like /usr/bin/python2
even though you're in powershell, that's probably what's going on.
I think a distribution-independent way is:
gtk-config --version
Or get the number of unique values for each column:
df.nunique()
dID 3
hID 5
mID 3
uID 5
dtype: int64
New in pandas 0.20.0
pd.DataFrame.agg
df.agg(['count', 'size', 'nunique'])
dID hID mID uID
count 8 8 8 8
size 8 8 8 8
nunique 3 5 3 5
You've always been able to do an agg
within a groupby
. I used stack
at the end because I like the presentation better.
df.groupby('mID').agg(['count', 'size', 'nunique']).stack()
dID hID uID
mID
A count 5 5 5
size 5 5 5
nunique 3 5 5
B count 2 2 2
size 2 2 2
nunique 2 2 2
C count 1 1 1
size 1 1 1
nunique 1 1 1
You can use brew to start/stop pgsql. I've following short cuts in my ~/.bashrc file
alias start-pg='brew services start postgresql'
alias stop-pg='brew services stop postgresql'
alias restart-pg='brew services restart postgresql'
This is a more accurate way to do it. It places decimals behind the seconds giving more precision.
$now = date('Y-m-d\TH:i:s.uP', time());
Notice the .uP
.

Esperento57's script doesn't work in older PowerShell versions. This example does:
Get-ChildItem -Path "C:\temp" -Recurse -force -ErrorAction SilentlyContinue | where {($_.LastwriteTime -lt (Get-Date).AddDays(-15) ) -and (! $_.PSIsContainer)} | select name| Remove-Item -Verbose -Force -Recurse -ErrorAction SilentlyContinue
You don't need to convert your dates to timestamp before the sorting, but it's a good idea though because it will take more time to sort without it.
$data = array(
array(
"title" => "Another title",
"date" => "Fri, 17 Jun 2011 08:55:57 +0200"
),
array(
"title" => "My title",
"date" => "Mon, 16 Jun 2010 06:55:57 +0200"
)
);
function sortFunction( $a, $b ) {
return strtotime($a["date"]) - strtotime($b["date"]);
}
usort($data, "sortFunction");
var_dump($data);
Well it depends, if you want to bind datas, there shouldn't be any formatting in it, otherwise you can bind-html
and do description.replace(/\\n/g, '<br>')
not sure it's what you want though.
You can convert (ie. force) the column data to text... Try this (Note: These instructions are based on Excel 2007)...
The following steps should force Excel to treat the column as text:
Open your spreadsheet with Excel.
Select the whole column that contains your "mostly numeric data" by clicking on the column header.
Click on the Data tab on the ribbon menu.
Select Text to Columns. This will bring up the Convert Text to Columns Wizard.
-On Step 1: Click Next
-On Step 2: Click Next
-On Step 3: Select Text and click Finish
Save your Excel sheet.
Retry the import using the SQL Server 2005 Import Data Wizard.
Also, here's a link to another question which has additional responses:
Import Data Wizard Does Not Like Data Type I Choose For A Column
Here are some of your options:
char a1[][14] = { "blah", "hmm" };
char* a2[] = { "blah", "hmm" };
char (*a3[])[] = { &"blah", &"hmm" }; // only since you brought up the syntax -
printf(a1[0]); // prints blah
printf(a2[0]); // prints blah
printf(*a3[0]); // prints blah
The advantage of a2
is that you can then do the following with string literals
a2[0] = "hmm";
a2[1] = "blah";
And for a3
you may do the following:
a3[0] = &"hmm";
a3[1] = &"blah";
For a1
you will have to use strcpy()
(better yet strncpy()
) even when assigning string literals. The reason is that a2
, and a3
are arrays of pointers and you can make their elements (i.e. pointers) point to any storage, whereas a1
is an array of 'array of chars' and so each element is an array that "owns" its own storage (which means it gets destroyed when it goes out of scope) - you can only copy stuff into its storage.
This also brings us to the disadvantage of using a2
and a3
- since they point to static storage (where string literals are stored) the contents of which cannot be reliably changed (viz. undefined behavior), if you want to assign non-string literals to the elements of a2
or a3
- you will first have to dynamically allocate enough memory and then have their elements point to this memory, and then copy the characters into it - and then you have to be sure to deallocate the memory when done.
Bah - I miss C++ already ;)
p.s. Let me know if you need examples.
I faced the same issue while development and needed to get the hash key to test sharing on facebook, and while solving this I went through couple of issues
1- the command facebook provide to get the hash key by using openSSL command didn't give me the right hash that I got by extracting the signature from Package info with code. getting the hash by the second way was correct.
2- For some reason, In the documentation they tell you to go to developer settings and add the hash key for 'Sample App' there, I thought every hashkey for a developer should be there, and that was my mistake, every app has it's own hash keys field to add to, go to your app/settings/android.
well that was it.. and for the records I used openssl-0.9.8k_X64 on a Windows 7 x64 bit and it just generates a wrong hash I don't know why
I used this code to get the hash:
private void printKeyHash() {
// Add code to print out the key hash
try {
PackageInfo info = getPackageManager().getPackageInfo("YOUR PACKAGE NAME", PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
Log.e("KeyHash:", e.toString());
} catch (NoSuchAlgorithmException e) {
Log.e("KeyHash:", e.toString());
}
}
but be careful that this may not also print in logs the correct keyhash, at least on my device and machine, when I debug it, in a watch it shows the correct hash just before printing the logs, but in logs it shows another hash and the first one was the correct one.
anyway you can also use a command or eclipse to view the SHA hexadecimal sequence for your key and convert it to base 64 online, there are websites that may help http://tomeko.net/online_tools/hex_to_base64.php?lang=en
Good luck

Well, the shortest way I know of, is following:
psql -U {user_name} -d {database_name} -f {file_path} -h {host_name}
database_name: Which database should you insert your file data in.
file_path: Absolute path to the file through which you want to perform the importing.
host_name: The name of the host. For development purposes, it is mostly localhost
.
Upon entering this command in console, you will be prompted to enter your password.
import functools
class Example:
def wrapper(func):
@functools.wraps(func)
def wrap(self, *args, **kwargs):
print("inside wrap")
return func(self, *args, **kwargs)
return wrap
@wrapper
def method(self):
print("METHOD")
wrapper = staticmethod(wrapper)
e = Example()
e.method()
you can use $nbsp; for a single space, if you like just using single allows you single space instead of using creating own class

#include <sstream>
and use the fully qualified name i.e. std::stringstream ss;
If lists always have the same structure, as in the example, then a simpler solution is
mapply(c, first, second, SIMPLIFY=FALSE)
assertj variant
import org.assertj.core.api.Assertions;
Assertions.assertThat(actualStr).contains(subStr);
I would suggest the following:
String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName);
I would say that the basic difference is this:
Grids are used as computing/storage platform.
We start talking about cloud computing when it offers services. I would almost say that cloud computing is higher-level grid. Now I know these are not definitions, but maybe it will make it more clear.
As far as application domains go, grids require users (developers mostly) to actually create services from low-level functions that grid offers. Cloud will offer complete blocks of functionality that you can use in your application.
Example (you want to create physical simulation of ball dropping from certain height): Grid: Study how to compute physics on a computer, create appropriate code, optimize it for certain hardware, think about paralellization, set inputs send application to grid and wait for answer
Cloud: Set diameter of a ball, material from pre-set types, height from which the ball is dropping, etc and ask for results
I would say that if you created OS for grid, you would actually create cloud OS.
If all you want is XSD, LiquidXML has a free version that does XSDs, and its got a GUI to it so you can tweak the XSD if you like. Anyways nowadays I write my own XSDs by hand, but its all thanks to this app.
you can use class with static methods that return an instance of that class
class MyClass {
constructor(a,b,c,d){
this.a = a
this.b = b
this.c = c
this.d = d
}
static BAndCInstance(b,c){
return new MyClass(null,b,c)
}
static BAndDInstance(b,d){
return new MyClass(null,b, null,d)
}
}
//new Instance just with a and other is nul this can
//use for other params that are first in constructor
const myclass=new MyClass(a)
//an Instance that has b and c params
const instanceWithBAndC = MyClass.BAndCInstance(b,c)
//another example for b and d
const instanceWithBAndD = MyClass.BAndDInstance(b,d)
with this pattern you can create multi constructor
Provided that any element has the id attribute on a webpage. One could simply link/jump to the element that is referenced by the tag.
Within the same page:
<div id="markOne"> ..... </div>
......
<a href="#markOne">Jump to markOne</a>
Other page:
<div id="http://randomwebsite.com/mypage.html#markOne">
Jumps to the markOne element in the mypage of the linked website
</div>
The targets don't necessarily have an anchor element.
You can go check this fiddle out.
You can do it in your batch file by parsing the output of:
SELECT * FROM pg_user WHERE usename = 'my_user'
and then running psql.exe
once again if the role does not exist.

In February 2017, they merged a PR adding this feature, they released in April 2017.
so to spy on getters/setters you use:
const spy = spyOnProperty(myObj, 'myGetterName', 'get');
where myObj is your instance, 'myGetterName' is the name of that one defined in your class as get myGetterName() {}
and the third param is the type get
or set
.
You can use the same assertions that you already use with the spies created with spyOn
.
So you can for example:
const spy = spyOnProperty(myObj, 'myGetterName', 'get'); // to stub and return nothing. Just spy and stub.
const spy = spyOnProperty(myObj, 'myGetterName', 'get').and.returnValue(1); // to stub and return 1 or any value as needed.
const spy = spyOnProperty(myObj, 'myGetterName', 'get').and.callThrough(); // Call the real thing.
Here's the line in the github source code where this method is available if you are interested.
Answering the original question, with jasmine 2.6.1, you would:
const spy = spyOnProperty(myObj, 'valueA', 'get').andReturn(1);
expect(myObj.valueA).toBe(1);
expect(spy).toHaveBeenCalled();
substring(field, 1,3) will work on your examples.
select substring(field, 1,3) from table
Also, if the alphabetic part is of variable length, you can do this to extract the alphabetic part:
select substring(field, 1, PATINDEX('%[1234567890]%', field) -1)
from table
where PATINDEX('%[1234567890]%', field) > 0
This code is a little more defensive, before opening a connection, check state. If connection state is Broken then we should try to close it. Broken means that the connection was previously opened and not functioning correctly. The second condition determines that connection state must be closed before attempting to open it again so the code can be called repeatedly.
// Defensive database opening logic.
if (_databaseConnection.State == ConnectionState.Broken) {
_databaseConnection.Close();
}
if (_databaseConnection.State == ConnectionState.Closed) {
_databaseConnection.Open();
}
Because the compiler needs to see them in order to inline them. And headers files are the "components" which are commonly included in other translation units.
#include "file.h"
// Ok, now me (the compiler) can see the definition of that inline function.
// So I'm able to replace calls for the actual implementation.
Assuming you want to assign false

Using the abc module for abstract base classes seems to do the trick.
from abc import ABCMeta, abstractmethod
class IInterface:
__metaclass__ = ABCMeta
@classmethod
def version(self): return "1.0"
@abstractmethod
def show(self): raise NotImplementedError
class MyServer(IInterface):
def show(self):
print 'Hello, World 2!'
class MyBadServer(object):
def show(self):
print 'Damn you, world!'
class MyClient(object):
def __init__(self, server):
if not isinstance(server, IInterface): raise Exception('Bad interface')
if not IInterface.version() == '1.0': raise Exception('Bad revision')
self._server = server
def client_show(self):
self._server.show()
# This call will fail with an exception
try:
x = MyClient(MyBadServer)
except Exception as exc:
print 'Failed as it should!'
# This will pass with glory
MyClient(MyServer()).client_show()
We were also facing this issue when using IE version 11 to access our React app (create-react-app with react version 16.0.0 with jQuery v3.1.1) on the enterprise intranet. To solve it, i simply followed the directions at this url which are also listed below:
Make sure to set the DOCTYPE to standards mode by making sure the first line of the master file is: <!DOCTYPE html>
Force IE 11 to use the latest internal version by including the following meta tag in the head tag: <meta http-equiv="X-UA-Compatible" content="IE=edge;" />
NOTE: I did not face the problem when using IE to access the app in development mode on my local machine (localhost:3000). The problem occurred only when accessing the app deployed to the DEV server on the company Intranet, probably because of some company wide Windows OS policy settings and/or IE Internet Options.
This is quite an old question, but I'm going to provide a modern solution that's been available since ES6 - export and import:
In first.js
:
let colorcodes = <whatever>;
export default colorcodes //or a different export statement
In second.js
:
import colorcodes from <path-to-first.js> //or a matching import statement
If you're trying to launch a specific activity instead of running the launcher one.
When you select that activity. the android studio might through this error,
Either you need to make it launcher activity, just like answered by few others.
or you need to add android:exported="true"
inside your activity tag inside manifest. It allows any external tool to run your specific activity directly without making it a launcher activity
You can also just use the pipeline with the AddScript Method:
string cmdArg = ".\script.ps1 -foo bar"
Collection<PSObject> psresults;
using (Pipeline pipeline = _runspace.CreatePipeline())
{
pipeline.Commands.AddScript(cmdArg);
pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output);
psresults = pipeline.Invoke();
}
return psresults;
It will take a string, and whatever parameters you pass it.
