I am using Android Studio 0.8.1. I have a project's gradle file like below:
android {
compileSdkVersion 19
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "com.omersonmez.widgets.hotspot"
minSdkVersion 15
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
My emulator was android 4.0. So i modified my emulator and made api level 4.0.3(apilevel 15). It worked.
These are usually to make sure that the browser gets a new version when the site gets updated with a new version, e.g. as part of our build process we'd have something like this:
/Resources/Combined.css?v=x.x.x.buildnumber
Since this changes with every new code push, the client's forced to grab a new version, just because of the querystring. Look at this page (at the time of this answer) for example:
<link ... href="http://sstatic.net/stackoverflow/all.css?v=c298c7f8233d">
I think instead of a revision number the SO team went with a file hash, which is an even better approach, even with a new release, the browsers only forced to grab a new version when the file actually changes.
Both of these approaches allow you to set the cache header to something ridiculously long, say 20 years...yet when it changes, you don't have to worry about that cache header, the browser sees a different querystring and treats it as a different, new file.
I would prefer to store the image in a directory, then store a reference to the image file in the database.
However, if you do store the image in the database, you should partition your database so the image column resides in a separate file.
You can read more about using filegroups here http://msdn.microsoft.com/en-us/library/ms179316.aspx.
If after calling "csrutil disabled" still your command does not work, try with "sudo" in terminal, for example:
sudo mv geckodriver /usr/local/bin
And it should work.
You can use os.sep:
>>> import os
>>> os.sep

Docker images are stored as filesystem layers. Every command in the Dockerfile creates a layer. You can also create layers by using docker commit
from the command line after making some changes (via docker run
probably).
These layers are stored by default under /var/lib/docker
. While you could (theoretically) cherry pick files from there and install it in a different docker server, is probably a bad idea to play with the internal representation used by Docker.
When you push your image, these layers are sent to the registry (the docker hub registry, by default… unless you tag your image with another registry prefix) and stored there. When pushing, the layer id is used to check if you already have the layer locally or it needs to be downloaded. You can use docker history
to peek at which layers (other images) are used (and, to some extent, which command created the layer).
As for options to share an image without pushing to the docker hub registry, your best options are:
docker save
an image or docker export
a container. This will output a tar file to standard output, so you will like to do something like docker save 'dockerizeit/agent' > dk.agent.latest.tar
. Then you can use docker load
or docker import
in a different host.
Host your own private registry. - Outdated, see comments See the docker registry image. We have built an s3 backed registry which you can start and stop as needed (all state is kept on the s3 bucket of your choice) which is trivial to setup. This is also an interesting way of watching what happens when pushing to a registry
Use another registry like quay.io (I haven't personally tried it), although whatever concerns you have with the docker hub will probably apply here too.

Its always best to use homebrew to update or install python. In terminal type:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)
This will install homebrew (it takes sometime depending on your internet speed)
Then, in terminal, type
brew update
This will first update brew (you don't have to do that if you already have the latest version)
then type
brew upgrade python
This brew will update python to the latest viable version.
That should do it.
What is the newline character in the C language: \r or \n?
The new-line may be thought of a some char
and it has the value of '\n'
. C11 5.2.1
This C new-line comes up in 3 places: C source code, as a single char
and as an end-of-line in file I/O when in text mode.
Many compilers will treat source text as ASCII. In that case, codes 10, sometimes 13, and sometimes paired 13,10 as new-line for source code. Had the source code been in another character set, different codes may be used. This new-line typically marks the end of a line of source code (actually a bit more complicated here), // comment, and # directives.
In source code, the 2 characters \
and n
represent the char
new-line as \n
. If ASCII is used, this char
would have the value of 10.
In file I/O, in text mode, upon reading the bytes of the input file (and stdin), depending on the environment, when bytes with the value(s) of 10 (Unix), 13,10, (*1) (Windows), 13 (Old Mac??) and other variations are translated in to a '\n'. Upon writing a file (or stdout), the reverse translation occurs.
Note: File I/O in binary mode makes no translation.
The '\r'
in source code is the carriage return char
.
(*1) A lone 13 and/or 10 may also translate into \n
.
The value of hjust
and vjust
are only defined between 0 and 1:
Source: ggplot2, Hadley Wickham, page 196
(Yes, I know that in most cases you can use it beyond this range, but don't expect it to behave in any specific way. This is outside spec.)
hjust
controls horizontal justification and vjust
controls vertical justification.
An example should make this clear:
td <- expand.grid(
hjust=c(0, 0.5, 1),
vjust=c(0, 0.5, 1),
angle=c(0, 45, 90),
text="text"
)
ggplot(td, aes(x=hjust, y=vjust)) +
geom_point() +
geom_text(aes(label=text, angle=angle, hjust=hjust, vjust=vjust)) +
facet_grid(~angle) +
scale_x_continuous(breaks=c(0, 0.5, 1), expand=c(0, 0.2)) +
scale_y_continuous(breaks=c(0, 0.5, 1), expand=c(0, 0.2))
To understand what happens when you change the hjust
in axis text, you need to understand that the horizontal alignment for axis text is defined in relation not to the x-axis, but to the entire plot (where this includes the y-axis text). (This is, in my view, unfortunate. It would be much more useful to have the alignment relative to the axis.)
DF <- data.frame(x=LETTERS[1:3],y=1:3)
p <- ggplot(DF, aes(x,y)) + geom_point() +
ylab("Very long label for y") +
theme(axis.title.y=element_text(angle=0))
p1 <- p + theme(axis.title.x=element_text(hjust=0)) + xlab("X-axis at hjust=0")
p2 <- p + theme(axis.title.x=element_text(hjust=0.5)) + xlab("X-axis at hjust=0.5")
p3 <- p + theme(axis.title.x=element_text(hjust=1)) + xlab("X-axis at hjust=1")
library(ggExtra)
align.plots(p1, p2, p3)
To explore what happens with vjust
aligment of axis labels:
DF <- data.frame(x=c("a\na","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()
p1 <- p + theme(axis.text.x=element_text(vjust=0, colour="red")) +
xlab("X-axis labels aligned with vjust=0")
p2 <- p + theme(axis.text.x=element_text(vjust=0.5, colour="red")) +
xlab("X-axis labels aligned with vjust=0.5")
p3 <- p + theme(axis.text.x=element_text(vjust=1, colour="red")) +
xlab("X-axis labels aligned with vjust=1")
library(ggExtra)
align.plots(p1, p2, p3)
The join feature supported by Mongodb 3.2 and later versions. You can use joins by using aggregate query.
You can do it using below example :
db.users.aggregate([
// Join with user_info table
{
$lookup:{
from: "userinfo", // other table name
localField: "userId", // name of users table field
foreignField: "userId", // name of userinfo table field
as: "user_info" // alias for userinfo table
}
},
{ $unwind:"$user_info" }, // $unwind used for getting data in object or for one record only
// Join with user_role table
{
$lookup:{
from: "userrole",
localField: "userId",
foreignField: "userId",
as: "user_role"
}
},
{ $unwind:"$user_role" },
// define some conditions here
{
$match:{
$and:[{"userName" : "admin"}]
}
},
// define which fields are you want to fetch
{
$project:{
_id : 1,
email : 1,
userName : 1,
userPhone : "$user_info.phone",
role : "$user_role.role",
}
}
]);
This will give result like this:
{
"_id" : ObjectId("5684f3c454b1fd6926c324fd"),
"email" : "[email protected]",
"userName" : "admin",
"userPhone" : "0000000000",
"role" : "admin"
}
Hope this will help you or someone else.
Thanks
For disk space, if you have Java 6, you can use the getTotalSpace and getFreeSpace methods on File. If you're not on Java 6, I believe you can use Apache Commons IO to get some of the way there.
I don't know of any cross platform way to get CPU usage or Memory usage I'm afraid.
I was going insane trying to get my js files to refresh and I tried everything. Then I did a header check and remembered I was using Cloudflare!
In Cloudflare you can use dev mode to disable proxy.

You have various possibilies. The most simple and the most ugly is:
XAML
<Button Name="cmdCommand" Click="Button_Clicked" Content="Command"/>
Code Behind
private void Button_Clicked(object sender, RoutedEventArgs e) {
FrameworkElement fe=sender as FrameworkElement;
((YourClass)fe.DataContext).DoYourCommand();
}
Another solution (better) is to provide a ICommand-property on your YourClass
. This command will have already a reference to your YourClass
-object and therefore can execute an action on this class.
XAML
<Button Name="cmdCommand" Command="{Binding YourICommandReturningProperty}" Content="Command"/>
Because during writing this answer, a lot of other answers were posted, I stop writing more. If you are interested in one of the ways I showed or if you think I have made a mistake, make a comment.
Your main problem is thinking that the variable you declared outside of the template is the same variable being "set" inside the choose statement. This is not how XSLT works, the variable cannot be reassigned. This is something more like what you want:
<xsl:template match="class">
<xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
<xsl:variable name="subexists">
<xsl:choose>
<xsl:when test="joined-subclass">true</xsl:when>
<xsl:otherwise>false</xsl:otherwise>
</xsl:choose>
</xsl:variable>
subexists: <xsl:value-of select="$subexists" />
</xsl:template>
And if you need the variable to have "global" scope then declare it outside of the template:
<xsl:variable name="subexists">
<xsl:choose>
<xsl:when test="/path/to/node/joined-subclass">true</xsl:when>
<xsl:otherwise>false</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:template match="class">
subexists: <xsl:value-of select="$subexists" />
</xsl:template>

From the documentation:
The $.browser property is deprecated in jQuery 1.3, and its functionality may be moved to a team-supported plugin in a future release of jQuery.
So, yes, it is deprecated, but your existing implementations will continue to work. If the functionality is removed, it will likely be easily accessible using a plugin.
As to whether there is an alternative... The answer is "yes, probably". It is far, far better to do feature detection using $.support
rather than browser detection: detect the actual feature you need, not the browser that provides it. Most important features that vary from browser to browser are detected with that.
Update 16 February 2013: In jQuery 1.9, this feature was removed (docs). It is far better not to use it. If you really, really must use its functionality, you can restore it with the jQuery Migrate plugin.
Works in IE9 documentMode for me.
Without a X-UA-Compatible
header/meta to set an explicit documentMode, you'll get a mode based on:
You can change these settings from ‘Tools -> Compatibility view settings’ from the IE menu. Of course that menu is now sneakily hidden, so you won't see it until you press Alt.
As a site author, if you're confident that your site complies to standards (renders well in other browsers, and uses feature-sniffing to decide what browser workarounds to use), I suggest using:
<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>
or the HTTP header:
X-UA-Compatible: IE=Edge
to get the latest renderer whatever IE version is in use.

Check these steps.
Best practice of getting length is use length
filter returns the number of items of a sequence or mapping, or the length of a string. For example: {{ notcount | length }}
But you can calculate count of elements in for
loop. For example:
{% set count = 0 %}
{% for nc in notcount %}
{% set count = count + 1 %}
{% endfor %}
{{ count }}
This solution helps if you want to calculate count of elements by condition, for example you have a property name
inside object and you want to calculate count of objects with not empty names:
{% set countNotEmpty = 0 %}
{% for nc in notcount if nc.name %}
{% set countNotEmpty = countNotEmpty + 1 %}
{% endfor %}
{{ countNotEmpty }}

Here is one way of doing it (Thanks to Android Documentation though!):
Add the following into a file (say customshape.xml) and then place it in (res/drawable/customshape.xml)
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#SomeGradientBeginColor"
android:endColor="#SomeGradientEndColor"
android:angle="270"/>
<corners
android:bottomRightRadius="7dp"
android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp"
android:topRightRadius="7dp"/>
</shape>
Once you are done with creating this file, just set the background in one of the following ways:
Through Code:
listView.setBackgroundResource(R.drawable.customshape);
Through XML, just add the following attribute to the container (ex: LinearLayout or to any fields):
android:background="@drawable/customshape"

So I ran into this today.
Was attempting to validate an uploaded CSV file's MIME type by looking at $_FILES['upload_file']['type']
, but for certain users on various browsers (and not necessarily the same browsers between said users; for instance it worked fine for me in FF but for another user it didn't work on FF) the $_FILES['upload_file']['type']
was coming up as "application/vnd.ms-excel" instead of the expected "text/csv" or "text/plain".
So I resorted to using the (IMHO) much more reliable finfo_* functions something like this:
$acceptable_mime_types = array('text/plain', 'text/csv', 'text/comma-separated-values');
if (!empty($_FILES) && array_key_exists('upload_file', $_FILES) && $_FILES['upload_file']['error'] == UPLOAD_ERR_OK) {
$tmpf = $_FILES['upload_file']['tmp_name'];
// Make sure $tmpf is kosher, then:
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime_type = finfo_file($finfo, $tmpf);
if (!in_array($mime_type, $acceptable_mime_types)) {
// Unacceptable mime type.
}
}
The correct syntax to do this on your relations is:
Event::whereHas('participants', function ($query) {
return $query->where('IDUser', '=', 1);
})->get();

The problem is in your pod files deployment target iOS Version not in your project deployment target iOS Version, so you need to change the deployment iOS version for your pods as well to anything higher than 8.0 to do so open your project workspace and do this:
1- Click on pods.
2- Select each project and target and click on build settings.
3- Under Deployment section change the iOS Deployment Target version to anything more than 8.0 (better to try the same project version).
4- Repeat this for every other project in your pods then run the app.
You are asking a lot of questions that you could answer yourself by reading the documentation, so I'll give you a general advice: read it and experiment in the python shell. You'll see that itemgetter
returns a callable:
>>> func = operator.itemgetter(1)
>>> func(a)
['Paul', 22, 'Car Dealer']
>>> func(a[0])
8
To do it in a different way, you can use lambda
:
a.sort(key=lambda x: x[1])
And reverse it:
a.sort(key=operator.itemgetter(1), reverse=True)
Sort by more than one column:
a.sort(key=operator.itemgetter(1,2))
See the sorting How To.
Yow can change the DropDownStyle in properties to DropDownList. This will not show the TextBox for filter.

Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.
In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.
Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.
To avoid 'Unclosed block: CssSyntaxError' errors being thrown from sass compilers add a ';' to the end of @content.

You don't actually need the bundle as the ADT can be used with just any latest Eclipse IDE.
Download latest eclipse.
Download latest ADT plugin ADT-XX.X.X.zip
. As of this answer the current version is ADT-23.0.7.zip (More versions at http://developer.android.com/tools/sdk/eclipse-adt.html)
Open Eclipse and follow the following steps:
Help
> Install New Software
> Add
> Archive
Developer Tools
, click Next
, accept any licenses and Finish
After restarting Eclipse, if you are not able to open a layout file go to step 4 but instead of selecting archive add https://dl-ssl.google.com/android/eclipse/ in the Location:
textbox. Press Ok
, update the ADT and restart Eclipse. Close and reopen the layout files and you'll be good to go.
Run the Android SDK Manager to update its components.

if not exist "%USERPROFILE%\.qgis-custom\" (
mkdir "%USERPROFILE%\.qgis-custom" 2>nul
if not errorlevel 1 (
xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)
)
You have it almost done. The logic is correct, just some little changes.
This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).
If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.
If everyting is ok, files are copied.
All paths are quoted to avoid problems with spaces.
It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files
mkdir "%USERPROFILE%\.qgis-custom" 2>nul
if not errorlevel 1 (
xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)
In both code samples, files are not copied if the folder is not being created during the script execution.
EDITED - As dbenham comments, the same code can be written as a single line
md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
The code after the &&
will only be executed if the previous command does not set errorlevel. If mkdir
fails, xcopy
is not executed.

i just wrapped a div around them and made it align center. then you don't need any css on the buttons to center them.
<div class="buttonHolder">
<input value="Search" title="Search" type="submit" id="btn_s">
<input value="I'm Feeling Lucky" title="I'm Feeling Lucky" name="lucky" type="submit" id="btn_i">
</div>
.buttonHolder{ text-align: center; }
queryParams
queryParams
is another input of routerLink
where they can be passed like
<a [routerLink]="['../']" [queryParams]="{prop: 'xxx'}">Somewhere</a>
fragment
<a [routerLink]="['../']" [queryParams]="{prop: 'xxx'}" [fragment]="yyy">Somewhere</a>
routerLinkActiveOptions
To also get routes active class set on parent routes:
[routerLinkActiveOptions]="{ exact: false }"
To pass query parameters to this.router.navigate(...)
use
let navigationExtras: NavigationExtras = {
queryParams: { 'session_id': sessionId },
fragment: 'anchor'
};
// Navigate to the login page with extras
this.router.navigate(['/login'], navigationExtras);

I don't see an obvious problem with the above.
It's possible your ldap.conf
is being overridden, but the command-line options will take precedence, ldapsearch
will ignore BINDDN
in the main ldap.conf
, so the only parameter that could be wrong is the URI.
(The order is ETCDIR/ldap.conf
then ~/ldaprc
or ~/.ldaprc
and then ldaprc
in the current directory, though there environment variables which can influence this too, see man ldapconf
.)
Try an explicit URI:
ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base -H ldap://localhost
or prevent defaults with:
LDAPNOINIT=1 ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base
If that doesn't work, then some troubleshooting (you'll probably need the full path to the slapd
binary for these):
make sure your slapd.conf
is being used and is correct (as root)
slapd -T test -f slapd.conf -d 65535
You may have a left-over or default slapd.d
configuration directory which takes preference over your slapd.conf
(unless you specify your config explicitly with -f
, slapd.conf
is officially deprecated in OpenLDAP-2.4). If you don't get several pages of output then your binaries were built without debug support.
stop OpenLDAP, then manually start slapd
in a separate terminal/console with debug enabled (as root, ^C to quit)
slapd -h ldap://localhost -d 481
then retry the search and see if you can spot the problem (there will be a lot of schema noise in the start of the output unfortunately). (Note: running slapd
without the -u
/-g
options can change file ownerships which can cause problems, you should usually use those options, probably -u ldap -g ldap
)
if debug is enabled, then try also
ldapsearch -v -d 63 -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base
Or you can use
<select [(ngModel)]="Answers[''+question.Name+'']" ng-options="option for option in question.Options">
</select>
Using MySQL, only this approach was working for me:

Sometime it will override by some rendering UI CSS. Better to use:

You can use this function to modify JSON.stringify
to encode arrays
, just post it near the beginning of your script (check the link above for more detail):
// Upgrade for JSON.stringify, updated to allow arrays
(function(){
// Convert array to object
var convArrToObj = function(array){
var thisEleObj = new Object();
if(typeof array == "object"){
for(var i in array){
var thisEle = convArrToObj(array[i]);
thisEleObj[i] = thisEle;
}
}else {
thisEleObj = array;
}
return thisEleObj;
};
var oldJSONStringify = JSON.stringify;
JSON.stringify = function(input){
if(oldJSONStringify(input) == '[]')
return oldJSONStringify(convArrToObj(input));
else
return oldJSONStringify(input);
};
})();
JSON (= JavaScript Object Notation), is a lightweight and fast mechanism to convert Javascript objects into a string and vice versa.
Since Javascripts objects consists of key/value
pairs its very easy to use and access JSON that way.
So if we have an object:
var myObj = {
foo: 'bar',
base: 'ball',
deep: {
java: 'script'
}
};
We can convert that into a string by calling window.JSON.stringify(myObj);
with the result of "{"foo":"bar","base":"ball","deep":{"java":"script"}}"
.
The other way around, we would call window.JSON.parse("a json string like the above");
.
JSON.parse()
returns a javascript object/array on success.
alert(myObj.deep.java); // 'script'
window.JSON
is not natively available in all browser. Some "older" browser need a little javascript plugin which offers the above mentioned functionality. Check http://www.json.org for further information.
The static keyword can be used in several different ways in Java and in almost all cases it is a modifier which means the thing it is modifying is usable without an enclosing object instance.
Java is an object oriented language and by default most code that you write requires an instance of the object to be used.
public class SomeObject {
public int someField;
public void someMethod() { };
public Class SomeInnerClass { };
}
In order to use someField, someMethod, or SomeInnerClass I have to first create an instance of SomeObject.
public class SomeOtherObject {
public void doSomeStuff() {
SomeObject anInstance = new SomeObject();
anInstance.someField = 7;
anInstance.someMethod();
//Non-static inner classes are usually not created outside of the
//class instance so you don't normally see this syntax
SomeInnerClass blah = anInstance.new SomeInnerClass();
}
}
If I declare those things static then they do not require an enclosing instance.
public class SomeObjectWithStaticStuff {
public static int someField;
public static void someMethod() { };
public static Class SomeInnerClass { };
}
public class SomeOtherObject {
public void doSomeStuff() {
SomeObjectWithStaticStuff.someField = 7;
SomeObjectWithStaticStuff.someMethod();
SomeObjectWithStaticStuff.SomeInnerClass blah = new SomeObjectWithStaticStuff.SomeInnerClass();
//Or you can also do this if your imports are correct
SomeInnerClass blah2 = new SomeInnerClass();
}
}
Declaring something static has several implications.
First, there can only ever one value of a static field throughout your entire application.
public class SomeOtherObject {
public void doSomeStuff() {
//Two objects, two different values
SomeObject instanceOne = new SomeObject();
SomeObject instanceTwo = new SomeObject();
instanceOne.someField = 7;
instanceTwo.someField = 10;
//Static object, only ever one value
SomeObjectWithStaticStuff.someField = 7;
SomeObjectWithStaticStuff.someField = 10; //Redefines the above set
}
}
The second issue is that static methods and inner classes cannot access fields in the enclosing object (since there isn't one).
public class SomeObjectWithStaticStuff {
private int nonStaticField;
private void nonStaticMethod() { };
public static void someStaticMethod() {
nonStaticField = 7; //Not allowed
this.nonStaticField = 7; //Not allowed, can never use *this* in static
nonStaticMethod(); //Not allowed
super.someSuperMethod(); //Not allowed, can never use *super* in static
}
public static class SomeStaticInnerClass {
public void doStuff() {
someStaticField = 7; //Not allowed
nonStaticMethod(); //Not allowed
someStaticMethod(); //This is ok
}
}
}
The static keyword can also be applied to inner interfaces, annotations, and enums.
public class SomeObject {
public static interface SomeInterface { };
public static @interface SomeAnnotation { };
public static enum SomeEnum { };
}
In all of these cases the keyword is redundant and has no effect. Interfaces, annotations, and enums are static by default because they never have a relationship to an inner class.
This just describes what they keyword does. It does not describe whether the use of the keyword is a bad idea or not. That can be covered in more detail in other questions such as Is using a lot of static methods a bad thing?
There are also a few less common uses of the keyword static. There are static imports which allow you to use static types (including interfaces, annotations, and enums not redundantly marked static) unqualified.
//SomeStaticThing.java
public class SomeStaticThing {
public static int StaticCounterOne = 0;
}
//SomeOtherStaticThing.java
public class SomeOtherStaticThing {
public static int StaticCounterTwo = 0;
}
//SomeOtherClass.java
import static some.package.SomeStaticThing.*;
import some.package.SomeOtherStaticThing.*;
public class SomeOtherClass {
public void doStuff() {
StaticCounterOne++; //Ok
StaticCounterTwo++; //Not ok
SomeOtherStaticThing.StaticCounterTwo++; //Ok
}
}
Lastly, there are static initializers which are blocks of code that are run when the class is first loaded (which is usually just before a class is instantiated for the first time in an application) and (like static methods) cannot access non-static fields or methods.
public class SomeObject {
private static int x;
static {
x = 7;
}
}
When you get in this state, try performing a Rebuild-All. If this fixes the problem, you may have the same issue I had.
Some background (my understanding):
SQLite has 1 managed assembly (System.Data.SQLite.dll) and several platform specific assemblies (SQLite.Interop.dll). When installing SQLite with Nuget, Nuget will add the platform specific assemblies to your project (within several folders: \x86, \x64), and configures these dlls to "Copy Always".
Upon load, the managed assembly will search for platform specific assemblies inside the \x86 and \x64 folders. You can see more on that here. The exception is this managed assembly attempting to find the relevant (SQLite.Interop.dll) inside these folders (and failing).
My Scenario:
I have 2 projects in my solution; a WPF app, and a class library. The WPF app references the class library, and the class library references SQLite (installed via Nuget).
The issue for me was when I modify only the WPF app, VS attempts to do a partial rebuild (realizing that the dependent dll hasn't changed). Somewhere in this process, VS cleans the content of the \x86 and \x64 folders (blowing away SQLite.Interop.dll). When I do a full Rebuild-All, VS copies the folders and their contents correctly.
My Solution:
To fix this, I ended up adding a Post-Build process using xcopy to force copying the \x86 and \x64 folders from the class library to my WPF project \bin directory.
Alternatively, you could do fancier things with the build configuration / output directories.
class Program
{
public static EventHandler AsyncHandler;
static void Main(string[] args)
{
AsyncHandler+= async (sender, eventArgs) => { await AsyncMain(); };
AsyncHandler?.Invoke(null, null);
}
private async Task AsyncMain()
{
//Your Async Code
}
}

Another use that I've been putting to good purpose is fetching data from multiple sources. In the example below, I'm fetching multiple, independent JSON schema objects used in an existing application for validation between a client and a REST server. In this case, I don't want the browser-side application to start loading data before it has all the schemas loaded. $.when.apply().then() is perfect for this. Thank to Raynos for pointers on using then(fn1, fn2) to monitor for error conditions.
fetch_sources = function (schema_urls) {
var fetch_one = function (url) {
return $.ajax({
url: url,
data: {},
contentType: "application/json; charset=utf-8",
dataType: "json",
});
}
return $.map(schema_urls, fetch_one);
}
var promises = fetch_sources(data['schemas']);
$.when.apply(null, promises).then(
function () {
var schemas = $.map(arguments, function (a) {
return a[0]
});
start_application(schemas);
}, function () {
console.log("FAIL", this, arguments);
});
Yes, you can include custom fonts. Refer to the documentation on UIFont, specifically, the fontWithName:size:
method.
1) Make sure you include the font in your resources folder.
2) The "name" of the font is not necessarily the filename.
3) Make sure you have the legal right to use that font. By including it in your app, you're also distributing it, and you need to have the right to do that.
Are you meaning?
data2 <- data1[good,]
With
data1[good]
you're selecting columns in a wrong way (using a logical vector of complete rows).
Consider that parameter pollutant
is not used; is it a column name that you want to extract? if so it should be something like
data2 <- data1[good, pollutant]
Furthermore consider that you have to rbind
the data.frame
s inside the for
loop, otherwise you get only the last data.frame (its completed.cases)
And last but not least, i'd prefer generating filenames eg with
id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")
A little modified chunk of ?sprintf
The string fmt
(in our case "%3d"
) contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through ...
. The allowed conversion specifications start with a %
and end with one of the letters in the set aAdifeEgGosxX%
. These letters denote the following types:
d
: integerEg a more general example
sprintf("I am %10d years old", 25)
[1] "I am 25 years old"

Sure, you just call it from within the SP, there's no special syntax.
Ex:
PROCEDURE some_sp
AS
BEGIN
some_other_sp('parm1', 10, 20.42);
END;
If the procedure is in a different schema than the one the executing procedure is in, you need to prefix it with schema name.
PROCEDURE some_sp
AS
BEGIN
other_schema.some_other_sp('parm1', 10, 20.42);
END;
You cannot iterate through a dictionary while its changing during for loop. Make a casting to list and iterate over that list, it works for me.
for key in list(d):
if not d[key]:
d.pop(key)
The problem is due to SIGPIPE handling. You can solve this problem using the following code:
from signal import signal, SIGPIPE, SIG_DFL
signal(SIGPIPE,SIG_DFL)
See here for background on this solution. Better answer here.
You can pass $state to your controller and then when the page loads and calls the getter in the controller you call $state.go('index') or whatever partial you want to load. Done.
When a module is loaded from a file in Python, __file__
is set to its path. You can then use that with other functions to find the directory that the file is located in.
Taking your examples one at a time:
A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.
B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.
C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.
You can see the various values returned from these here:
import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))
and make sure you run it from different locations (such as ./text.py
, ~/python/text.py
and so forth) to see what difference that makes.
I just want to address some confusion first. __file__
is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.
http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.
In this case __file__
is an attribute of a module (a module object). In Python a .py
file is a module. So import amodule
will have an attribute of __file__
which means different things under difference circumstances.
Taken from the docs:
__file__
is the pathname of the file from which the module was loaded, if it was loaded from a file. The__file__
attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.
In your case the module is accessing it's own __file__
attribute in the global namespace.
To see this in action try:
# file: test.py
print globals()
print __file__
And run:
python test.py
{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py
You could also do
var x = $('#element').height(); // or any changing value
$('selector').css({'top' : x + 'px'});
OR
You can use directly
$('#element').css( "height" )
The difference between .css( "height" )
and .height()
is that the latter returns a unit-less pixel value (for example, 400
) while the former returns a value with units intact (for example, 400px
). The .height() method is recommended when an element's height needs to be used in a mathematical calculation. jquery doc
Anyone interested in doing this should read the documentation of the Django Sessions framework. It stores a session ID in the user's cookies, but maps all the cookies-like data to your database. This is an improvement on the typical cookies-based workflow for HTTP requests.
Here is an example with a Django view ...
def homepage(request):
request.session.setdefault('how_many_visits', 0)
request.session['how_many_visits'] += 1
print(request.session['how_many_visits'])
return render(request, 'home.html', {})
If you keep visiting the page over and over, you'll see the value start incrementing up from 1 until you clear your cookies, visit on a new browser, go incognito, or do anything else that sidesteps Django's Session ID cookie.
Its work perfectly
ALTER TABLE `products` ADD `LastUpdate` varchar(200) NULL;
But if you want more precise in table then you can try AFTER
.
ALTER TABLE `products` ADD `LastUpdate` varchar(200) NULL AFTER `column_name`;
It will add LastUpdate
column after specified column name (column_name).
Since MySQL 5.6.X you can do this:
ALTER TABLE `schema`.`users`
CHANGE COLUMN `created` `created` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP ;
That way your column will be updated with the current timestamp when a new row is inserted, or updated.
If you're using MySQL Workbench, you can just put CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
in the DEFAULT value field, like so:
http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-5.html
check for this by calling the library jquery after the noconflict.js or that this calling more than once jquery library after the noconflict.js
As others have said, Dir::foreach
is a good option here. However, note that Dir::foreach
and Dir::entries
will always include .
and ..
(the current and parent directories). You will generally not want to work on them, so you can use Dir::each_child
or Dir::children
(as suggested by ma11hew28) or do something like this:
Dir.foreach('/path/to/dir') do |filename|
next if filename == '.' or filename == '..'
# Do work on the remaining files & directories
end
Dir::foreach
and Dir::entries
(as well as Dir::each_child
and Dir::children
) also include hidden files & directories. Often this is what you want, but if it isn't, you need to do something to skip over them.
Alternatively, you might want to look into Dir::glob
which provides simple wildcard matching:
Dir.glob('/path/to/dir/*.rb') do |rb_filename|
# Do work on files & directories ending in .rb
end
The two methods of adding do generate slightly different byte code:
17: iconst_2
18: iload 4
20: iload 4
22: imul
23: imul
24: iadd
For 2 * (i * i)
vs:
17: iconst_2
18: iload 4
20: imul
21: iload 4
23: imul
24: iadd
For 2 * i * i
.
And when using a JMH benchmark like this:
@Warmup(iterations = 5, batchSize = 1)
@Measurement(iterations = 5, batchSize = 1)
@Fork(1)
@BenchmarkMode(Mode.AverageTime)
@OutputTimeUnit(TimeUnit.MILLISECONDS)
@State(Scope.Benchmark)
public class MyBenchmark {
@Benchmark
public int noBrackets() {
int n = 0;
for (int i = 0; i < 1000000000; i++) {
n += 2 * i * i;
}
return n;
}
@Benchmark
public int brackets() {
int n = 0;
for (int i = 0; i < 1000000000; i++) {
n += 2 * (i * i);
}
return n;
}
}
The difference is clear:
# JMH version: 1.21
# VM version: JDK 11, Java HotSpot(TM) 64-Bit Server VM, 11+28
# VM options: <none>

MyBenchmark.noBrackets 1000000000 avgt 5 512.464 ± 11.098 ms/op
What you observe is correct, and not just an anomaly of your benchmarking style (i.e. no warmup, see How do I write a correct micro-benchmark in Java?)
Running again with Graal:
# JMH version: 1.21
# VM version: JDK 11, Java HotSpot(TM) 64-Bit Server VM, 11+28
# VM options: -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+UseJVMCICompiler

MyBenchmark.brackets 1000000000 avgt 5 335.100 ± 23.085 ms/op
MyBenchmark.noBrackets 1000000000 avgt 5 331.163 ± 50.670 ms/op
You see that the results are much closer, which makes sense, since Graal is an overall better performing, more modern, compiler.
So this is really just up to how well the JIT compiler is able to optimize a particular piece of code, and doesn't necessarily have a logical reason to it.
Just tested and QDir::currentPath()
does return the path from which I called my executable.
And a symlink does not "exist". If you are executing an exe from that path you are effectively executing it from the path the symlink points to.

if (string.IsNullOrWhiteSpace(strInput)) { return false;}
strInput = strInput.Trim();
if ((strInput.StartsWith("{") && strInput.EndsWith("}")) || //For object
(strInput.StartsWith("[") && strInput.EndsWith("]"))) //For array
{
try
{
var obj = JToken.Parse(strInput);
return true;
}
catch (JsonReaderException jex)
{
//Exception in parsing json
Console.WriteLine(jex.Message);
return false;
}
catch (Exception ex) //some other exception
{
Console.WriteLine(ex.ToString());
return false;
}
}
else
{
return false;
}
}
The reason to add checks for {
or [
etc was based on the fact that JToken.Parse
would parse the values such as "1234"
or "'a string'"
as a valid token. The other option could be to use both JObject.Parse
and JArray.Parse
in parsing and see if anyone of them succeeds, but I believe checking for {}
and []
should be easier. (Thanks @RhinoDevel for pointing it out)
Without JSON.Net
You can utilize .Net framework 4.5 System.Json namespace ,like:
string jsonString = "someString";
try
{
var tmpObj = JsonValue.Parse(jsonString);
}
catch (FormatException fex)
{
//Invalid json format
Console.WriteLine(fex);
}
catch (Exception ex) //some other exception
{
Console.WriteLine(ex.ToString());
}
(But, you have to install System.Json
through Nuget package manager using command: PM> Install-Package System.Json -Version 4.0.20126.16343
on Package Manager Console) (taken from here)
Non-Code way:
Usually, when there is a small json string and you are trying to find a mistake in the json string, then I personally prefer to use available on-line tools. What I usually do is:
Make sure you have enabled TextQualified option and set it to be "
.
This could be done without creating the extra node, with just an another Node reference passing to the parameters (Node temp).
private static Node mergeTwoLists(Node nodeList1, Node nodeList2, Node temp) {
if(nodeList1 == null) return nodeList2;
if(nodeList2 == null) return nodeList1;
if(nodeList1.data <= nodeList2.data){
temp = nodeList1;
temp.next = mergeTwoLists(nodeList1.next, nodeList2, temp);
}
else{
temp = nodeList2;
temp.next = mergeTwoLists(nodeList1, nodeList2.next, temp);
}
return temp;
}
Dim timeFormat As String = "yyyy-MM-dd HH:mm:ss"
objBL.date = Convert.ToDateTime(txtDate.Value).ToString(timeFormat)
You don't need --header "Content-Length: $LENGTH".
curl --request POST --data-binary "@template_entry.xml" $URL
Note that GET request does not support content body widely.
Also remember that POST request have 2 different coding schema. This is first form:
$ nc -l -p 6666 & $ curl --request POST --data-binary "@README" http://localhost:6666 POST / HTTP/1.1 User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6 Host: localhost:6666 Accept: */* Content-Length: 9309 Content-Type: application/x-www-form-urlencoded Expect: 100-continue .. -*- mode: rst; coding: cp1251; fill-column: 80 -*- .. rst2html.py README README.html .. contents::
You probably request this:
-F/--form name=content (HTTP) This lets curl emulate a filled-in form in which a user has pressed the submit button. This causes curl to POST data using the Content- Type multipart/form-data according to RFC2388. This enables uploading of binary files etc. To force the 'content' part to be a file, prefix the file name with an @ sign. To just get the content part from a file, prefix the file name with the symbol <. The difference between @ and < is then that @ makes a file get attached in the post as a file upload, while the < makes a text field and just get the contents for that text field from a file.
I would recommend doing it like this to keep things in line with HTML5.
<meta charset="UTF-8">
EG:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
</body>
</html>
I use $.data - http://api.jquery.com/jquery.data/
//Set value 7 to data-id
$.data(this, 'id', 7);
//Get value from data-id
alert( $(this).data("id") ); // => outputs 7
I think you'll find your answer if you refer to this post: Deserialize JSON into C# dynamic object?
There are various ways of achieving what you want here. The System.Web.Helpers.Json approach (a few answers down) seems to be the simplest.
The error message says it all: strs[sum-1]
is a tuple, not a string. If you show more of your code someone will probably be able to help you. Without that we can only guess.
You could also print out the unique value in "file" using the cat
command by piping to sort
and uniq
cat file | sort | uniq -u
function isPalindrome(s,i) {
return (i=i||0)<0||i>=s.length>>1||s[i]==s[s.length-1-i]&&isPalindrome(s,++i);
}
use like:
isPalindrome('racecar');
as it defines "i" itself
Fiddle: http://jsfiddle.net/namcx0yf/9/
This is ~25 times faster than the standard answer below.
function checkPalindrome(str) {
return str == str.split('').reverse().join('');
}

Although the solution is difficult to read and maintain, I would recommend understanding it to demonstrate non-branching with recursion and bit shifting to impress your next interviewer.
The || and && are used for control flow like "if" "else". If something left of || is true, it just exits with true. If something is false left of || it must continue. If something left of && is false, it exits as false, if something left of a && is true, it must continue. This is considered "non-branching" as it does not need if-else interupts, rather its just evaluated.
1. Used an initializer not requiring "i" to be defined as an argument. Assigns "i" to itself if defined, otherwise initialize to 0. Always is false so next OR condition is always evaluated.
(i = i || 0) < 0
2. Checks if "i" went half way but skips checking middle odd char. Bit shifted here is like division by 2 but to lowest even neighbor division by 2 result. If true then assumes palindrome since its already done. If false evaluates next OR condition.
i >= s.length >> 1
3. Compares from beginning char and end char according to "i" eventually to meet as neighbors or neighbor to middle char. If false exits and assumes NOT palindrome. If true continues on to next AND condition.
s[i] == s[s.length-1-i]
4. Calls itself again for recursion passing the original string as "s". Since "i" is defined for sure at this point, it is pre-incremented to continue checking the string's position. Returns boolean value indicating if palindrome.
isPalindrome(s,++i)
A simple for loop is still about twice as fast as my fancy answer (aka KISS principle)
function fastestIsPalindrome(str) {
var len = Math.floor(str.length / 2);
for (var i = 0; i < len; i++)
if (str[i] !== str[str.length - i - 1])
return false;
return true;
}

So you want the code to the pin it button without installing the button? If so just paste this code in the place of the url of the page you're pinning from. It should function as a pin it button without the button.

I eventually used:
weather["Temp"] = weather["Temp"].convert_objects(convert_numeric=True)
It worked just fine, except that I got the following message.
C:\ProgramData\Anaconda3\lib\site-packages\ipykernel_launcher.py:3: FutureWarning:
convert_objects is deprecated. Use the data-type specific converters pd.to_datetime, pd.to_timedelta and pd.to_numeric.
Yes, that's the cause of the App Store rejection. If your ad-hoc provisioning profile has the aps-environment key, it means your app is configured correctly in the Apple Provisioning Portal. All you need to do is delete the App Store distribution profile on your local machine, then re-download and install the distribution profile from the Provisioning Portal. This new one should contain the aps-environment key.

If you are on Azure you need you can now, you need to have Manag. Studio 2014 and update hotfix: http://blogs.msdn.com/b/sqlreleaseservices/archive/2014/12/18/sql-server-2014-management-studio-updated-support-for-the-latest-azure-sql-database-update-v12-preview.aspx
When I create an executable jar with dependencies (using this guide), all properties files are packaged into that jar too. How to stop it from happening? Thanks.
Properties files from where? Your main jar? Dependencies?
In the former case, putting resources under src/test/resources
as suggested is probably the most straight forward and simplest option.
In the later case, you'll have to create a custom assembly descriptor with special excludes/exclude
in the unpackOptions
.
If you're giving the same seed, that's normal. That's an important feature allowing tests.
Check this to understand pseudo random generation and seeds:
A pseudorandom number generator (PRNG), also known as a deterministic random bit generator DRBG, is an algorithm for generating a sequence of numbers that approximates the properties of random numbers. The sequence is not truly random in that it is completely determined by a relatively small set of initial values, called the PRNG's state, which includes a truly random seed.
If you want to have different sequences (the usual case when not tuning or debugging the algorithm), you should call the zero argument constructor which uses the nanoTime to try to get a different seed every time. This Random
instance should of course be kept outside of your method.
Your code should probably be like this:
private Random generator = new Random();
double randomGenerator() {
return generator.nextDouble()*0.5;
}
You need to set permission for the user controls .

These are good answers but detached from a full answer as to how you would get a form to send data and handle that response. This will demonstrate how to add a member to a list with v3.0 of the API from an HTML page via jquery .ajax()
.
In Mailchimp:
zipcode
as a custom field in the list BEFORE I did the API call.create
method which requires the use of HTTP POST
requests. There are other options in here that require PUT
if you want to be able to modify/delete subs.HTML:
<form id="pfb-signup-submission" method="post">
<div class="sign-up-group">
<input type="text" name="pfb-signup" id="pfb-signup-box-fname" class="pfb-signup-box" placeholder="First Name">
<input type="text" name="pfb-signup" id="pfb-signup-box-lname" class="pfb-signup-box" placeholder="Last Name">
<input type="email" name="pfb-signup" id="pfb-signup-box-email" class="pfb-signup-box" placeholder="[email protected]">
<input type="text" name="pfb-signup" id="pfb-signup-box-zip" class="pfb-signup-box" placeholder="Zip Code">
</div>
<input type="submit" class="submit-button" value="Sign-up" id="pfb-signup-button"></a>
<div id="pfb-signup-result"></div>
</form>
Key things:
<form>
a unique ID and don't forget the method="post"
attribute so the form works. #signup-result
is where you will deposit the feedback from the PHP script.PHP:
<?php
/*
* Add a 'member' to a 'list' via mailchimp API v3.x
* @ http://developer.mailchimp.com/documentation/mailchimp/reference/lists/members/#create-post_lists_list_id_members
*
* ================
* BACKGROUND
* Typical use case is that this code would get run by an .ajax() jQuery call or possibly a form action
* The live data you need will get transferred via the global $_POST variable
* That data must be put into an array with keys that match the mailchimp endpoints, check the above link for those
* You also need to include your API key and list ID for this to work.
* You'll just have to go get those and type them in here, see README.md
* ================
*/
// Set API Key and list ID to add a subscriber
$api_key = 'your-api-key-here';
$list_id = 'your-list-id-here';
/* ================
* DESTINATION URL
* Note: your API URL has a location subdomain at the front of the URL string
* It can vary depending on where you are in the world
* To determine yours, check the last 3 digits of your API key
* ================
*/
$url = 'https://us5.api.mailchimp.com/3.0/lists/' . $list_id . '/members/';
/* ================
* DATA SETUP
* Encode data into a format that the add subscriber mailchimp end point is looking for
* Must include 'email_address' and 'status'
* Statuses: pending = they get an email; subscribed = they don't get an email
* Custom fields go into the 'merge_fields' as another array
* More here: http://developer.mailchimp.com/documentation/mailchimp/reference/lists/members/#create-post_lists_list_id_members
* ================
*/
$pfb_data = array(
'email_address' => $_POST['emailname'],
'status' => 'pending',
'merge_fields' => array(
'FNAME' => $_POST['firstname'],
'LNAME' => $_POST['lastname'],
'ZIPCODE' => $_POST['zipcode']
),
);
// Encode the data
$encoded_pfb_data = json_encode($pfb_data);
// Setup cURL sequence
$ch = curl_init();
/* ================
* cURL OPTIONS
* The tricky one here is the _USERPWD - this is how you transfer the API key over
* _RETURNTRANSFER allows us to get the response into a variable which is nice
* This example just POSTs, we don't edit/modify - just a simple add to a list
* _POSTFIELDS does the heavy lifting
* _SSL_VERIFYPEER should probably be set but I didn't do it here
* ================
*/
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, 'user:' . $api_key);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $encoded_pfb_data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$results = curl_exec($ch); // store response
$response = curl_getinfo($ch, CURLINFO_HTTP_CODE); // get HTTP CODE
$errors = curl_error($ch); // store errors
curl_close($ch);
// Returns info back to jQuery .ajax or just outputs onto the page
$results = array(
'results' => $result_info,
'response' => $response,
'errors' => $errors
);
// Sends data back to the page OR the ajax() in your JS
echo json_encode($results);
?>
Key things:
CURLOPT_USERPWD
handles the API key and Mailchimp doesn't really show you how to do this. CURLOPT_RETURNTRANSFER
gives us the response in such a way that we can send it back into the HTML page with the .ajax()
success
handler.json_encode
on the data you received.JS:
// Signup form submission
$('#pfb-signup-submission').submit(function(event) {
event.preventDefault();
// Get data from form and store it
var pfbSignupFNAME = $('#pfb-signup-box-fname').val();
var pfbSignupLNAME = $('#pfb-signup-box-lname').val();
var pfbSignupEMAIL = $('#pfb-signup-box-email').val();
var pfbSignupZIP = $('#pfb-signup-box-zip').val();
// Create JSON variable of retreived data
var pfbSignupData = {
'firstname': pfbSignupFNAME,
'lastname': pfbSignupLNAME,
'email': pfbSignupEMAIL,
'zipcode': pfbSignupZIP
};
// Send data to PHP script via .ajax() of jQuery
$.ajax({
type: 'POST',
dataType: 'json',
url: 'mailchimp-signup.php',
data: pfbSignupData,
success: function (results) {
$('#pfb-signup-box-fname').hide();
$('#pfb-signup-box-lname').hide();
$('#pfb-signup-box-email').hide();
$('#pfb-signup-box-zip').hide();
$('#pfb-signup-result').text('Thanks for adding yourself to the email list. We will be in touch.');
console.log(results);
},
error: function (results) {
$('#pfb-signup-result').html('<p>Sorry but we were unable to add you into the email list.</p>');
console.log(results);
}
});
});
Key things:
JSON
data is VERY touchy on transfer. Here, I am putting it into an array and it looks easy. If you are having problems, it is likely because of how your JSON data is structured. Check this out!_POST
global variable. In this case it will be _POST['email']
, _POST['firstname']
, etc. But you could name them whatever you want - just remember what you name the keys of the data
part of your JSON transfer is how you access them in PHP.In "Package Explorer" view, Right click your test class, then "Build Path">>"Include", it should be OK.
You can edit style with pure Javascript. No library needed, supported by all browsers except IE where you need to set to ''
instead of null
(see comments).
var element = document.getElementById('sample_id');
element.style.width = null;
element.style.height = null;
For more information, you can refer to HTMLElement.style documentation on MDN.
What about :
import platform
h = platform.uname()[1]
Actually you may want to have a look to all the result in platform.uname()
You can try something like this:
public interface PersonRepository extends CrudRepository<Person, Long> {
@Query("select p from Person AS p"
+ " ,Name AS n"
+ " where p.forename = n.forename "
+ " and p.surname = n.surname"
+ " and n = :name")
Set<Person>findByName(@Param("name") Name name);
}
An abstract function cannot have functionality. You're basically saying, any child class MUST give their own version of this method, however it's too general to even try to implement in the parent class.
A virtual function, is basically saying look, here's the functionality that may or may not be good enough for the child class. So if it is good enough, use this method, if not, then override me, and provide your own functionality.
#include <stdint.h>
uintptr_t
standard type defined in the included standard header file.From the MSDN library:
The
First<TSource>(IEnumerable<TSource>)
method throws an exception if source contains no elements. To instead return a default value when the source sequence is empty, use theFirstOrDefault
method.
In Chrome, request with 'Content-Type:application/json' shows as Request PayedLoad and sends data as json object.
But request with 'Content-Type:application/x-www-form-urlencoded' shows Form Data and sends data as Key:Value Pair, so if you have array of object in one key it flats that key's value:
{ Id: 1,
name:'john',
phones:[{title:'home',number:111111,...},
{title:'office',number:22222,...}]
}
sends
{ Id: 1,
name:'john',
phones:[object object]
phones:[object object]
}
Yes there is a way to do it.
First declare a class.
//anyfile.ts
export class Custom
{
name: string,
empoloyeeID: number
}
Then in your component import the class
import {Custom} from '../path/to/anyfile.ts'
.....
export class FormComponent implements OnInit {
name: string;
empoloyeeID : number;
empList: Array<Custom> = [];
constructor() {
}
ngOnInit() {
}
onEmpCreate(){
//console.log(this.name,this.empoloyeeID);
let customObj = new Custom();
customObj.name = "something";
customObj.employeeId = 12;
this.empList.push(customObj);
this.name ="";
this.empoloyeeID = 0;
}
}
Another way would be to interfaces read the documentation once - https://www.typescriptlang.org/docs/handbook/interfaces.html
Also checkout this question, it is very interesting - When to use Interface and Model in TypeScript / Angular2
The answers provided (at the time of this post) are link only answers so I thought I would summarize the links into an answer and what I will be using.
When working to create Cross Browser Favicons (including touch icons) there are several things to consider.
The first (of course) is Internet Explorer. IE does not support PNG favicons until version 11. So our first line is a conditional comment for favicons in IE 9 and below:
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->
To cover the uses of the icon create it at 32x32 pixels. Notice the rel="shortcut icon"
for IE to recognize the icon it needs the word shortcut
which is not standard. Also we wrap the .ico
favicon in a IE conditional comment because Chrome and Safari will use the .ico
file if it is present, despite other options available, not what we would like.
The above covers IE up to IE 9. IE 11 accepts PNG favicons, however, IE 10 does not. Also IE 10 does not read conditional comments thus IE 10 won't show a favicon. With IE 11 and Edge available I don't see IE 10 in widespread use, so I ignore this browser.
For the rest of the browsers we are going to use the standard way to cite a favicon:
<link rel="icon" href="path/to/favicon.png">
This icon should be 196x196 pixels in size to cover all devices that may use this icon.
To cover touch icons on mobile devices we are going to use Apple's proprietary way to cite a touch icon:
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">
Using rel="apple-touch-icon-precomposed"
will not apply the reflective shine when bookmarked on iOS. To have iOS apply the shine use rel="apple-touch-icon"
. This icon should be sized to 180x180 pixels as that is the current size recommend by Apple for the latest iPhones and iPads. I have read Blackberry will also use rel="apple-touch-icon-precomposed"
.
As a note: Chrome for Android states:
The apple-touch-* are deprecated, and will be supported only for a short time. (Written as of beta for m31 of Chrome).
Custom Tiles for IE 11+ on Windows 8.1+
IE 11+ on Windows 8.1+ does offer a way to create pinned tiles for your site.
Microsoft recommends creating a few tiles at the following size:
Small: 128 x 128
Medium: 270 x 270
Wide: 558 x 270
Large: 558 x 558
These should be transparent images as we will define a color background next.
Once these images are created you should create an xml file called browserconfig.xml
with the following code:
<?xml version="1.0" encoding="utf-8"?>
<browserconfig>
<msapplication>
<tile>
<square70x70logo src="images/smalltile.png"/>
<square150x150logo src="images/mediumtile.png"/>
<wide310x150logo src="images/widetile.png"/>
<square310x310logo src="images/largetile.png"/>
<TileColor>#009900</TileColor>
</tile>
</msapplication>
</browserconfig>
Save this xml file in the root of your site. When a site is pinned IE will look for this file. If you want to name the xml file something different or have it in a different location add this meta tag to the head
:
<meta name="msapplication-config" content="path-to-browserconfig/custom-name.xml" />
For additional information on IE 11+ custom tiles and using the XML file visit Microsoft's website.
Putting it all together:
To put it all together the above code would look like this:
<!-- For IE 9 and below. ICO should be 32x32 pixels in size -->
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->
<!-- Touch Icons - iOS and Android 2.1+ 180x180 pixels in size. -->
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">
<!-- Firefox, Chrome, Safari, IE 11+ and Opera. 196x196 pixels in size. -->
<link rel="icon" href="path/to/favicon.png">
Windows Phone Live Tiles
If a user is using a Windows Phone they can pin a website to the start screen of their phone. Unfortunately, when they do this it displays a screenshot of your phone, not a favicon (not even the MS specific code referenced above). To make a "Live Tile" for Windows Phone Users for your website one must use the following code:
Here are detailed instructions from Microsoft but here is a synopsis:
Step 1
Create a square image for your website, to support hi-res screens create it at 768x768 pixels in size.
Step 2
Add a hidden overlay of this image. Here is example code from Microsoft:
<div id="TileOverlay" onclick="ToggleTileOverlay()" style='background-color: Highlight; height: 100%; width: 100%; top: 0px; left: 0px; position: fixed; color: black; visibility: hidden'>
<img src="customtile.png" width="320" height="320" />
<div style='margin-top: 40px'>
Add text/graphic asking user to pin to start using the menu...
</div>
</div>
Step 3
You then can add thew following line to add a pin to start link:
<a href="javascript:ToggleTileOverlay()">Pin this site to your start screen</a>
Microsoft recommends that you detect windows phone and only show that link to those users since it won't work for other users.
Step 4
Next you add some JS to toggle the overlay visibility
<script>
function ToggleTileOverlay() {
var newVisibility = (document.getElementById('TileOverlay').style.visibility == 'visible') ? 'hidden' : 'visible';
document.getElementById('TileOverlay').style.visibility = newVisibility;
}
</script>
Note on Sizes
I am using one size as every browser will scale down the image as necessary. I could add more HTML to specify multiple sizes if desired for those with a lower bandwidth but I am already compressing the PNG files heavily using TinyPNG and I find this unnecessary for my purposes. Also, according to philippe_b's answer Chrome and Firefox have bugs that cause the browser to load all sizes of icons. Using one large icon may be better than multiple smaller ones because of this.
Further Reading
For those who would like more details see the links below:
This is all you need:
background-repeat: no-repeat;
import re
re.sub('<.*?>', '', string)
"i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"
The re.sub
function takes a regular expresion and replace all the matches in the string with the second parameter. In this case, we are searching for all tags ('<.*?>'
) and replacing them with nothing (''
).
The ?
is used in re
for non-greedy searches.
More about the re module
.
if($("element_selector").attr('disabled') || $("element_selector").prop('disabled'))
{
// code when element is disabled
}
You can re-activate the actions by adding
this.delegateEvents(); // Re-activates the events for all the buttons
If you add it to the render function of a backbone js view, then you can use event.preventDefault() as required.
You can use $.isEmptyObject(json)
I think you can use MDC to change logging level programmatically. The code below is an example to change logging level on current thread. This approach does not create dependency to logback implementation (SLF4J API contains MDC).

U may do as I have written from my deleted account (ban for new posts :( there was). Its rather simple and nice looking.
Im using 3-rd one of these 3 ones usually, also I wasny checking 1 and 2 version.
from matplotlib.pyplot import cm
import numpy as np
#variable n should be number of curves to plot (I skipped this earlier thinking that it is obvious when looking at picture - sorry my bad mistake xD): n=len(array_of_curves_to_plot)
#version 1:
color=cm.rainbow(np.linspace(0,1,n))
for i,c in zip(range(n),color):
ax1.plot(x, y,c=c)
#or version 2: - faster and better:
color=iter(cm.rainbow(np.linspace(0,1,n)))
c=next(color)
plt.plot(x,y,c=c)
#or version 3:
color=iter(cm.rainbow(np.linspace(0,1,n)))
for i in range(n):
c=next(color)
ax1.plot(x, y,c=c)

In oracle db there is a trick for casting int to float (I suppose, it should also work in mysql):
select myintfield + 0.0 as myfloatfield from mytable
While @Heximal's answer works, I don't personally recommend it.
This is because it uses implicit casting. Although you didn't type CAST
, either the SUM()
or the 0.0
need to be cast to be the same data-types, before the +
can happen. In this case the order of precedence is in your favour, and you get a float on both sides, and a float as a result of the +
. But SUM(aFloatField) + 0
does not yield an INT, because the 0
is being implicitly cast to a FLOAT.
I find that in most programming cases, it is much preferable to be explicit. Don't leave things to chance, confusion, or interpretation.
If you want to be explicit, I would use the following.
CAST(SUM(sl.parts) AS FLOAT) * cp.price
-- using MySQL CAST FLOAT requires 8.0
You can try the following to see what happens...
CAST(SUM(sl.parts) AS NUMERIC(10,4)) * CAST(cp.price AS NUMERIC(10,4))
You dont have a function named assign()
, but a method with this name. PHP is not Java and in PHP you have to make clear, if you want to call a function
assign()
or a method
$object->assign()
In your case the call to the function resides inside another method. $this
always refers to the object, in which a method exists, itself.
$this->assign()
This is the SQL Order of execution of a Query,
You can check order of execution with examples from this article.
For you question below lines might be helpful and directly got from this article.
- GROUP BY --> The remaining rows after the WHERE constraints are applied are then grouped based on common values in the column specified in the GROUP BY clause. As a result of the grouping, there will only be as many rows as there are unique values in that column. Implicitly, this means that you should only need to use this when you have aggregate functions in your query.
- HAVING --> If the query has a GROUP BY clause, then the constraints in the HAVING clause are then applied to the grouped rows, discard the grouped rows that don't satisfy the constraint. Like the WHERE clause, aliases are also not accessible from this step in most databases.

According to Joshua Bloch's Effective Java (a book that can't be recommended enough, and which I bought thanks to continual mentions on stackoverflow):
The value 31 was chosen because it is an odd prime. If it were even and the multiplication overflowed, information would be lost, as multiplication by 2 is equivalent to shifting. The advantage of using a prime is less clear, but it is traditional. A nice property of 31 is that the multiplication can be replaced by a shift and a subtraction for better performance:
31 * i == (i << 5) - i
. Modern VMs do this sort of optimization automatically.

Jean-François Corbett's answer is perfect. To be exhaustive I would just like to add that with some restrictons you could also use UsedRange.Columns.Count
or UsedRange.Rows.Count
.
The problem is that UsedRange is not always updated when deleting rows/columns (at least until you reopen the workbook).
Reading from standard input, write 'code.py' as follows:
import sys
rep = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}
for line in sys.stdin:
for k, v in rep.iteritems():
line = line.replace(k, v)
print line
Then, execute the script with redirection or piping (http://en.wikipedia.org/wiki/Redirection_(computing))
python code.py < infile > outfile
angular.element(document).ready(function () {
// your code here

What I can quickly think of is, generate the pdf and store it in webapp/downloads/< RANDOM-FILENAME>.pdf from the code and send a forward to this file using HttpServletRequest
request.getRequestDispatcher("/downloads/<RANDOM-FILENAME>.pdf").forward(request, response);
or if you can configure your view resolver something like,
<bean id="pdfViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="order" value=”2"/>
<property name="prefix" value="/downloads/" />
<property name="suffix" value=".pdf" />
</bean>
then just return
return "RANDOM-FILENAME";
The registry is a no-go. You're not sure whether the user which uses your application, has sufficient rights to write to the registry.
You can use the app.config
file to save application-level settings (that are the same for each user who uses your application).
I would store user-specific settings in an XML file, which would be saved in Isolated Storage or in the SpecialFolder.ApplicationData directory.
Next to that, as from .NET 2.0, it is possible to store values back to the app.config
file.
Right click your project in eclipse, build path -> add external jars.
JavaScript is case-sensitive. The b

I encountered this error working in Talend. I was able to store S3 CSV files created from Redshift without a problem. The error occurred when I was trying to load the same S3 CSV files into an Amazon RDS MySQL database. I tried the default timestamp Talend timestamp formats but they were throwing exception:unparseable date when loading into MySQL.
This from the accepted answer helped me solve this problem:
By the way, the "unparseable date" exception can here only be thrown by SimpleDateFormat#parse(). This means that the inputDate isn't in the expected pattern "yyyy-MM-dd HH:mm:ss z". You'll probably need to modify the pattern to match the inputDate's actual pattern
The key to my solution was changing the Talend schema. Talend set the timestamp field to "date" so I changed it to "timestamp" then I inserted "yyyy-MM-dd HH:mm:ss z" into the format string column view a screenshot here talend schema
I had other issues with 12 hour and 24 hour timestamp translations until I added the "z" at the end of the timestamp string.
Since you are using C++11, lambda-expression is a nice&clean solution.
class blub {
void test() {}
public:
std::thread spawn() {
return std::thread( [this] { this->test(); } );
}
};
since this->
can be omitted, it could be shorten to:
std::thread( [this] { test(); } )
or just (deprecated)
std::thread( [=] { test(); } )
as you found, this is the preferred sql server method:
SELECT * FROM (
SELECT *, ROW_NUMBER() OVER (ORDER BY name) as row FROM sys.databases
) a WHERE a.row > 5 and a.row <= 10
Inside CONCATENATE
you can use TRANSPOSE
if you expand it (F9) then remove the surrounding {}
brackets like this recommends
=CONCATENATE(TRANSPOSE(B2:B19))
Becomes
=CONCATENATE("Oh ","combining ", "a " ...)
You may need to add your own separator on the end, say create a column C and transpose that column.
=B1&" "
=B2&" "
=B3&" "
Comparing websocket and webrtc is unfair.
Websocket is based on top of TCP. Packet's boundary can be detected from header information of a websocket packet unlike tcp.
Typically, webrtc makes use of websocket. The signalling for webrtc is not defined, it is upto the service provider what kind of signalling he wants to use. It may be SIP, HTTP, JSON or any text / binary message.
The signalling messages can be send / received using websocket.
iOS users also expect autocapitalization: In a standard text field, the first letter of a sentence in a case-sensitive language is automatically capitalized.
You can decide whether or not to implement such features; there is no dedicated API for any of the features just listed, so providing them is a competitive advantage.
Apple document is saying there is no API available for this feature and some other expected feature in a customkeyboard. so you need to find out your own logic to implement this.
Emil's answer is correct, but it's my understanding that inet_ntoa
is deprecated and that instead you should use inet_ntop
. If you are using IPv4, cast your struct sockaddr
to sockaddr_in
. Your code will look something like this:
struct addrinfo *res; // populated elsewhere in your code
struct sockaddr_in *ipv4 = (struct sockaddr_in *)res->ai_addr;
char ipAddress[INET_ADDRSTRLEN];
inet_ntop(AF_INET, &(ipv4->sin_addr), ipAddress, INET_ADDRSTRLEN);
printf("The IP address is: %s\n", ipAddress);
Take a look at this great resource for more explanation, including how to do this for IPv6 addresses.
As others have suggested, you are not clearly explaining your problem, what you are trying to do, or what your expectations are as to what this function is actually supposed to do.
If I have understood correctly, then you are expecting this function to refresh the page for you (you actually use the term "reloads the browser").
But this function is not intended to reload the browser.
All the function does, is to add (push) a new "state" onto the browser history, so that in future, the user will be able to return to this state that the web-page is now in.
Normally, this is used in conjunction with AJAX calls (which refresh only a part of the page).
For example, if a user does a search "CATS" in one of your search boxes, and the results of the search (presumably cute pictures of cats) are loaded back via AJAX, into the lower-right of your page -- then your page state will not be changed. In other words, in the near future, when the user decides that he wants to go back to his search for "CATS", he won't be able to, because the state doesn't exist in his history. He will only be able to click back to your blank search box.
Hence the need for the function
history.pushState({},"Results for `Cats`",'url.html?s=cats');
It is intended as a way to allow the programmer to specifically define his search into the user's history trail. That's all it is intended to do.
When the function is working properly, the only thing you should expect to see, is the address in your browser's address-bar change to whatever you specify in your URL.
If you already understand this, then sorry for this long preamble. But it sounds from the way you pose the question, that you have not.
As an aside, I have also found some contradictions between the way that the function is described in the documentation, and the way it works in reality. I find that it is not a good idea to use blank or empty values as parameters.
See my answer to this SO question. So I would recommend putting a description in your second parameter. From memory, this is the description that the user sees in the drop-down, when he clicks-and-holds his mouse over "back" button.
#include"stdio.h"
#include"conio.h"
#include"time.h"
void main()
{
time_t t;
int i;
srand(time(&t));
for(i=1;i<=10;i++)
printf("%c\t",rand()%10);
getch();
}
I didn't see this mentioned yet, but beans have a built-in method called getProperties()
.
So, to use it:
// What bean do we want to get?
$type = 'book';
$id = 13;
// Load the bean
$post = R::load($type,$id);
// Get the properties
$props = $post->getProperties();
// Print the JSON-encoded value
print json_encode($props);
This outputs:
{
"id": "13",
"title": "Oliver Twist",
"author": "Charles Dickens"
}
Now take it a step further. If we have an array of beans...
// An array of beans (just an example)
$series = array($post,$post,$post);
...then we could do the following:
Loop through the array with a foreach
loop.
Replace each element (a bean) with an array of the bean's properties.
So this...
foreach ($series as &$val) {
$val = $val->getProperties();
}
print json_encode($series);
...outputs this:
[
{
"id": "13",
"title": "Oliver Twist",
"author": "Charles Dickens"
},
{
"id": "13",
"title": "Oliver Twist",
"author": "Charles Dickens"
},
{
"id": "13",
"title": "Oliver Twist",
"author": "Charles Dickens"
}
]
Hope this helps!
You cannot use double binding with hidden field. The solution is to use brackets :
<input type="hidden" name="someData" value="{{data}}" /> {{data}}
EDIT : See this thread on github : https://github.com/angular/angular.js/pull/2574
EDIT:
Since Angular 1.2, you can use 'ng-value' directive to bind an expression to the value attribute of input. This directive should be used with input radio or checkbox but works well with hidden input.
Here is the solution using ng-value:
<input type="hidden" name="someData" ng-value="data" />
Here is a fiddle using ng-value with an hidden input: http://jsfiddle.net/6SD9N
Open a terminal window
cd into YOUR_PROJECT/ios
Remove the build folder with rm -r build
After that open your project in Xcode and run once. it will run with starting the server and create the main.jsbundle
file.
Now if you Run react-native run-ios
from terminal again it will work as expected.
Hope it will help!.
For Lambda lovers
protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
var boundFields = e.Row.Cells.Cast<DataControlFieldCell>()
.Select(cell => cell.ContainingField).Cast<BoundField>().ToList();
int idx = boundFields.IndexOf(
boundFields.FirstOrDefault(f => f.DataField == "ColName"));
e.Row.Cells[idx].Text = modification;
}
}
You should be able to add the style, like this (taken from source code for Ringdroid):
<style name="AudioFileInfoOverlayText">
<item name="android:paddingLeft">4px</item>
<item name="android:paddingBottom">4px</item>
<item name="android:textColor">#ffffffff</item>
<item name="android:textSize">12sp</item>
<item name="android:shadowColor">#000000</item>
<item name="android:shadowDx">1</item>
<item name="android:shadowDy">1</item>
<item name="android:shadowRadius">1</item>
</style>
And in your layout, use the style like this:
<TextView android:id="@+id/info"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
style="@style/AudioFileInfoOverlayText"
android:gravity="center" />
Edit: the source code can be viewed here: https://github.com/google/ringdroid
Edit2: To set this style programmatically, you'd do something like this (modified from this example to match ringdroid's resources from above)
TextView infoTextView = (TextView) findViewById(R.id.info);
infoTextView.setTextAppearance(getApplicationContext(),
R.style.AudioFileInfoOverlayText);
The signature for setTextAppearance
is
public void setTextAppearance (Context context, int resid)
Since: API Level 1
Sets the text color, size, style, hint color, and highlight color from the specified TextAppearance resource.
If this is for something that will be called a lot in an application instance, it's a lot faster to compile and cache dynamic code instead of using the activator or ConstructorInfo.Invoke()
. Two easy options for dynamic compilation are compiled Linq Expressions or some simple IL
opcodes and DynamicMethod
. Either way, the difference is huge when you start getting into tight loops or multiple calls.
Since you're returning a string as JSON, that string will include the opening and closing quotes in the raw response. So your response should probably look like:
"abc123XYZ=="
or whatever...You can try confirming this with Fiddler.
My guess is that the result.Content
is the raw string, including the quotes. If that's the case, then result.Content
will need to be deserialized before you can use it.

Define a converter:
public class RowIndexConverter : IValueConverter
{
public object Convert( object value, Type targetType,
object parameter, CultureInfo culture )
{
var row = (IDictionary<string, object>) value;
var key = (string) parameter;
return row.Keys.Contains( key ) ? row[ key ] : null;
}
public object ConvertBack( object value, Type targetType,
object parameter, CultureInfo culture )
{
throw new NotImplementedException( );
}
}
Bind to a custom definition of a Dictionary. There's lot of overrides that I've omitted, but the indexer is the important one, because it emits the property changed event when the value is changed. This is required for source to target binding.
public class BindableRow : INotifyPropertyChanged, IDictionary<string, object>
{
private Dictionary<string, object> _data = new Dictionary<string, object>( );
public object Dummy // Provides a dummy property for the column to bind to
{
get
{
return this;
}
set
{
var o = value;
}
}
public object this[ string index ]
{
get
{
return _data[ index ];
}
set
{
_data[ index ] = value;
InvokePropertyChanged( new PropertyChangedEventArgs( "Dummy" ) ); // Trigger update
}
}
}
In your .xaml file use this converter. First reference it:
<UserControl.Resources>
<ViewModelHelpers:RowIndexConverter x:Key="RowIndexConverter"/>
</UserControl.Resources>
Then, for instance, if your dictionary has an entry where the key is "Name", then to bind to it: use
<TextBlock Text="{Binding Dummy, Converter={StaticResource RowIndexConverter}, ConverterParameter=Name}">
Are you sure you have used the right instance? I ran into this problem and realized that something like 4 of the ubuntu instances i tried did not have SSH servers installed on them.
For a list of good servers see "Getting the images" about half way down. Sounds like you may be using something else... the default username is ubuntu on these images.
When building a GET
request, there is no body to the request, but rather everything goes on the URL. To build a URL (and properly percent escaping it), you can also use URLComponents
.
var url = URLComponents(string: "https://www.google.com/search/")!
url.queryItems = [
URLQueryItem(name: "q", value: "War & Peace")
]
The only trick is that most web services need +
character percent escaped (because they'll interpret that as a space character as dictated by the application/x-www-form-urlencoded
specification). But URLComponents
will not percent escape it. Apple contends that +
is a valid character in a query and therefore shouldn't be escaped. Technically, they are correct, that it is allowed in a query of a URI, but it has a special meaning in application/x-www-form-urlencoded
requests and really should not be passed unescaped.
Apple acknowledges that we have to percent escaping the +
characters, but advises that we do it manually:
var url = URLComponents(string: "https://www.wolframalpha.com/input/")!
url.queryItems = [
URLQueryItem(name: "i", value: "1+2")
]
url.percentEncodedQuery = url.percentEncodedQuery?.replacingOccurrences(of: "+", with: "%2B")
This is an inelegant work-around, but it works, and is what Apple advises if your queries may include a +
character and you have a server that interprets them as spaces.
So, combining that with your sendRequest
routine, you end up with something like:
func sendRequest(_ url: String, parameters: [String: String], completion: @escaping ([String: Any]?, Error?) -> Void) {
var components = URLComponents(string: url)!
components.queryItems = parameters.map { (key, value) in
URLQueryItem(name: key, value: value)
}
components.percentEncodedQuery = components.percentEncodedQuery?.replacingOccurrences(of: "+", with: "%2B")
let request = URLRequest(url: components.url!)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, // is there data
let response = response as? HTTPURLResponse, // is there HTTP response
(200 ..< 300) ~= response.statusCode, // is statusCode 2XX
error == nil else { // was there no error, otherwise ...
completion(nil, error)
return
}
let responseObject = (try? JSONSerialization.jsonObject(with: data)) as? [String: Any]
completion(responseObject, nil)
}
task.resume()
}
And you'd call it like:
sendRequest("someurl", parameters: ["foo": "bar"]) { responseObject, error in
guard let responseObject = responseObject, error == nil else {
print(error ?? "Unknown error")
return
}
// use `responseObject` here
}
Personally, I'd use JSONDecoder
nowadays and return a custom struct
rather than a dictionary, but that's not really relevant here. Hopefully this illustrates the basic idea of how to percent encode the parameters into the URL of a GET request.
See previous revision of this answer for Swift 2 and manual percent escaping renditions.
The first case is done using the insert()
method:
_sb.insert(0, "Hello ");
The latter case can be done using the overloaded + operator on Strings. This uses a StringBuilder behind the scenes:
String s2 = "Hello " + _s;
Where it is documented:
From the API documentation under the has_many association in "Module ActiveRecord::Associations::ClassMethods"
collection.build(attributes = {}, …) Returns one or more new objects of the collection type that have been instantiated with attributes and linked to this object through a foreign key, but have not yet been saved. Note: This only works if an associated object already exists, not if it‘s nil!
The answer to building in the opposite direction is a slightly altered syntax. In your example with the dogs,
Class Dog
has_many :tags
belongs_to :person
end
Class Person
has_many :dogs
end
d = Dog.new
d.build_person(:attributes => "go", :here => "like normal")
or even
t = Tag.new
t.build_dog(:name => "Rover", :breed => "Maltese")
You can also use create_dog to have it saved instantly (much like the corresponding "create" method you can call on the collection)
How is rails smart enough? It's magic (or more accurately, I just don't know, would love to find out!)
An integer can't be null but there is a really simple way of doing what you want to do. Use an if-then statement in which you check the integer's value against all possible values.
Example:
int x;
// Some Code...
if (x <= 0 || x > 0){
// What you want the code to do if x has a value
} else {
// What you want the code to do if x has no value
}
Disclaimer: I am assuming that Java does not automatically set values of numbers to 0 if it doesn't see a value.
you have to rename the column to an other name because TABLE
is reserved by Oracle.
You can see all reserved words of Oracle in the oracle view V$RESERVED_WORDS
.

Here comes the perfect example:
https://laravel.com/docs/5.8/database#listening-for-query-events
Open app\Providers\AppServiceProvider.php and add the following to Boot() function:
DB::listen(function ($query) {
var_dump([
$query->sql,
$query->bindings,
$query->time
]);
});
So you don't need to put DB::enableQuerylog()
and DB::getQuerylog()
in every function.
I figured out the demo and implemented it the following way:

PartialViewResult and JSONReuslt inherit from the base class ActionResult. so if return type is decided dynamically declare method output as ActionResult.

else if (parameter == "PartialView")
return PartialView("<ViewName>");
else

In cpp, you need to pay special attention to string types when using execvp
:
#include <iostream>
#include <string>
#include <cstring>
#include <stdio.h>
#include <unistd.h>
using namespace std;
const size_t MAX_ARGC = 15; // 1 command + # of arguments
char* argv[MAX_ARGC + 1]; // Needs +1 because of the null terminator at the end
// c_str() converts string to const char*, strdup converts const char* to char*
argv[0] = strdup(command.c_str());
// start filling up the arguments after the first command
size_t arg_i = 1;
while (cin && arg_i < MAX_ARGC) {
string arg;
cin >> arg;
if (arg.empty()) {
argv[arg_i] = nullptr;
break;
} else {
argv[arg_i] = strdup(arg.c_str());
}
++arg_i;
}
// Run the command with arguments
if (execvp(command.c_str(), argv) == -1) {
// Print error if command not found
cerr << "command '" << command << "' not found\n";
}

Another option: Do not float your right column; just give it a left margin to move it beyond the float. You'll need a hack or two to fix IE6, but that's the basic idea.
This:
document.getElementById('myField').onblur();
works because your element (the <input>
) has an attribute called "onblur" whose value is a function. Thus, you can call it. You're not telling the browser to simulate the actual "blur" event, however; there's no event object created, for example.
Elements do not have a "blur" attribute (or "method" or whatever), so that's why the first thing doesn't work.
It's quite clearly from their docs:
If you used componentWillReceiveProps for re-computing some data only when a prop changes, use a memoization helper instead.

Since I have been doing a bit of research in that field lately (Jan, '12), the most promising client is actually : WebSocket for Python. It support a normal socket that you can call like this :
ws = EchoClient('http://localhost:9000/ws')
The client
can be Threaded
or based on IOLoop
from Tornado project. This will allow you to create a multi concurrent connection client. Useful if you want to run stress tests.
The client also exposes the onmessage
, opened
and closed
methods. (WebSocket style).
BTW you can pass the error message directly to sys.exit:
if len(sys.argv) < 2:
sys.exit('Usage: %s database-name' % sys.argv[0])
if not os.path.exists(sys.argv[1]):
sys.exit('ERROR: Database %s was not found!' % sys.argv[1])
You will need to clone the ArrayList
by hand (by iterating over it and copying each element to a new ArrayList
), because clone()
will not do it for you. Reason for this is that the objects contained in the ArrayList
may not implement Clonable
themselves.
Edit: ... and that is exactly what Varkhan's code does.
Try this code. It works for me:
unzip(zipfile="<directory and filename>",
exdir="<directory where the content will be extracted>")
Example:
unzip(zipfile="./data/Data.zip",exdir="./data")
Always : If you always want vertical scrollbar, use overflow-y: scroll;
<div style="overflow-y: scroll;">

<div style="overflow-y: auto; height:150px; ">

0
in case of non-int:int(){ printf '%d' ${1:-} 2>/dev/null || :; }
int(){ expr 0 + ${1:-} 2>/dev/null||:; }
int(){ expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null||:; }
# This is a combination of numbers 1 and 2
int(){ expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null||:; }
If you want to get a non-zero status code on non-int, remove the ||:
(aka or true
) but leave the ;
# Wrapped in parens to call a subprocess and not `set` options in the main bash process
# In other words, you can literally copy-paste this code block into your shell to test
( set -eu;
tests=( 4 "5" "6foo" "bar7" "foo8.9bar" "baz" " " "" )
test(){ echo; type int; for test in "${tests[@]}"; do echo "got '$(int $test)' from '$test'"; done; echo "got '$(int)' with no argument"; }
int(){ printf '%d' ${1:-} 2>/dev/null||:; };
test
int(){ expr 0 + ${1:-} 2>/dev/null||:; }
test
int(){ expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null||:; }
test
int(){ printf '%d' $(expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null)||:; }
test
# unexpected inconsistent results from `bc`
int(){ bc<<<"${1:-}" 2>/dev/null||:; }
test
)
int is a function
int ()
{
printf '%d' ${1:-} 2> /dev/null || :
}

I got sent down this rabbit hole because the accepted answer is not compatible with set -o nounset
(aka set -u
)
# This works
$ ( number="3"; string="foo"; echo $((number)) $((string)); )
3 0
# This doesn't
$ ( set -u; number="3"; string="foo"; echo $((number)) $((string)); )
-bash: foo: unbound variable
if you are in dev mode with not valid certificate, why not just set weClient.setUseInsecureSSL(true)
. works for me
Very few posts suggest using LOGON_TYPE_NEW_CREDENTIALS
instead of LOGON_TYPE_NETWORK
or LOGON_TYPE_INTERACTIVE
. I had an impersonation issue with one machine connected to a domain and one not, and this fixed it.
The last code snippet in this post suggests that impersonating across a forest does work, but it doesn't specifically say anything about trust being set up. So this may be worth trying:
const int LOGON_TYPE_NEW_CREDENTIALS = 9;
const int LOGON32_PROVIDER_WINNT50 = 3;
bool returnValue = LogonUser(user, domain, password,
LOGON_TYPE_NEW_CREDENTIALS, LOGON32_PROVIDER_WINNT50,
ref tokenHandle);
MSDN says that LOGON_TYPE_NEW_CREDENTIALS
only works when using LOGON32_PROVIDER_WINNT50
.
this worked for me , in this way we setting the default value to empty string
@Html.TextBoxFor(m => m.Id, new { @Value = "" })
I had the same issue with one of my netbeans project.
Check whether you have correctly put the package name on all the classes. I got the same error message because i forgot to put the package name of a certain class (which was copied from another project).
Try using a StringBuilder object and use the appendline method. That might work.
Use the noinline
attribute:
int func(int arg) __attribute__((noinline))
{
}
You should probably use it both when you declare the function for external use and when you write the function.
taskkill /im myprocess.exe /f
The "/f" is for "force". If you know the PID, then you can specify that, as in:
taskkill /pid 1234 /f
Lots of other options are possible, just type taskkill /? for all of them. The "/t" option kills a process and any child processes; that may be useful to you.
REST is an architectural pattern for creating web services. A RESTful service is one that implements that pattern.
This error is happening because you are just opening html documents directly from the browser. To fix this you will need to serve your code from a webserver and access it on localhost. If you have Apache setup, use it to serve your files. Some IDE's have built in web servers, like JetBrains IDE's, Eclipse...
If you have Node.Js setup then you can use http-server. Just run npm install http-server -g
and you will be able to use it in terminal like http-server C:\location\to\app.

Use the Date property: Gets the date component of this instance.
var dateAndTime = DateTime.Now;
var date = dateAndTime.Date;
variable date
contain the date and the time part will be 00:00:00.
or
Console.WriteLine(DateTime.Now.ToString("dd/MM/yyyy"));
or
DateTime.ToShortDateString Method-
Console.WriteLine(DateTime.Now.ToShortDateString ());
@balalakshmi mentioned about the correct authentication settings. Authentication is only half of the problem, the other half is authorization.
If you're using Forms Authentication and standard controls like <asp:Login>
there are a couple of things you'll need to do to ensure that only your authenticated users can access secured pages.
In web.config
, under the <system.web>
section you'll need to disable anonymous access by default:
<authorization>
<deny users="?" />
</authorization>
Any pages that will be accessed anonymously (such as the Login.aspx page itself) will need to have an override that re-allows anonymous access. This requires a <location>
element and must be located at the <configuration>
level (outside the <system.web>
section), like this:
<!-- Anonymous files -->
<location path="Login.aspx">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
Note that you'll also need to allow anonymous access to any style sheets or scripts that are used by the anonymous pages:
<!-- Anonymous folders -->
<location path="styles">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
Be aware that the location's path
attribute is relative to the web.config
folder and cannot have a ~/
prefix, unlike most other path-type configuration attributes.
If you expect the data to be numeric in some form, and all you are interested in doing is converting the result to a numeric value, I would suggest:
for (Object o:list) {
Double.parseDouble(o.toString);
}
The only reason to have a return in a void function would be to exit early due to some conditional statement:
void foo(int y)
{
if(y == 0) return;
// do stuff with y
}
As unwind said: when the code ends, it ends. No need for an explicit return at the end.
In Spring Boot 2 the property in e.g. application.properties
is server.servlet.context-path=/myWebApp
to set the context path.
According to the PHP Documentation json_decode
function has a parameter named assoc which convert the returned objects into associative arrays
mixed json_decode ( string $json [, bool $assoc = FALSE ] )
Since assoc parameter is FALSE
by default, You have to set this value to TRUE
in order to retrieve an array.
Examine the below code for an example implication:
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json));
var_dump(json_decode($json, true));
which outputs:
object(stdClass)#1 (5) {
["a"] => int(1)
["b"] => int(2)
["c"] => int(3)
["d"] => int(4)
["e"] => int(5)
}
array(5) {
["a"] => int(1)
["b"] => int(2)
["c"] => int(3)
["d"] => int(4)
["e"] => int(5)
}
If you have a text file with loads of packages you need to add the -r flag
pip install --upgrade --no-deps --force-reinstall -r requirements.txt
