I am using Debian but this solution should work fine with Ubuntu.
You have to add a line in the neo4j-service script.
Here is what I have done :
nano /etc/init.d/neo4j-service
Add « ulimit –n 40000 » just before the start-stop-daemon line in the do_start section
Note that I am using version 2.0 Enterprise edition. Hope this will help you.
Actually, I have tried the above answer, but it did not seem to work.
To get my containers to acknowledge the ulimit
change, I had to update the docker.conf
file before starting them:
$ sudo service docker stop
$ sudo bash -c "echo \"limit nofile 262144 262144\" >> /etc/init/docker.conf"
$ sudo service docker start
ulimit -s unlimited
lets the stack grow unlimited.
This may prevent your program from crashing if you write programs by recursion, especially if your programs are not tail recursive (compilers can "optimize" those), and the depth of recursion is large.
demo

git fetch --all
demo
branch on localgit pull origin demo
master
branch. This branch will be completely changed with the code on demo
branchgit checkout master
master
branch and run this command.git reset --hard origin/demo
reset
means you will be resetting current branch
--hard
is a flag that means it will be reset without raising any merge conflict
origin/demo

A solution I came up with in 2015 for my framework. I called this type of promises Task
function createPromise(handler){
var resolve, reject;
var promise = new Promise(function(_resolve, _reject){
resolve = _resolve;
reject = _reject;
if(handler) handler(resolve, reject);
})
promise.resolve = resolve;
promise.reject = reject;
return promise;
}
// create
var promise = createPromise()
promise.then(function(data){ alert(data) })
// resolve from outside
promise.resolve(200)
The other answers are preferable, but for a pure Bash solution, I've modified the script in my answer here to be able to output a continuous stream of hex characters representing the contents of a file. (Its normal mode is to emulate hexdump -C
.)
.values()
You can call the values()
method on your enum.
for (Direction dir : Direction.values()) {
// do what you want
}
This values()
method is implicitly declared by the compiler. So it is not listed on Enum
doc.
I had the same issue where a private value was not set because Mockito does not call super constructors. Here is how I augment mocking with reflection.
First, I created a TestUtils class that contains many helpful utils including these reflection methods. Reflection access is a bit wonky to implement each time. I created these methods to test code on projects that, for one reason or another, had no mocking package and I was not invited to include it.
public class TestUtils {
// get a static class value
public static Object reflectValue(Class<?> classToReflect, String fieldNameValueToFetch) {
try {
Field reflectField = reflectField(classToReflect, fieldNameValueToFetch);
reflectField.setAccessible(true);
Object reflectValue = reflectField.get(classToReflect);
return reflectValue;
} catch (Exception e) {
fail("Failed to reflect "+fieldNameValueToFetch);
}
return null;
}
// get an instance value
public static Object reflectValue(Object objToReflect, String fieldNameValueToFetch) {
try {
Field reflectField = reflectField(objToReflect.getClass(), fieldNameValueToFetch);
Object reflectValue = reflectField.get(objToReflect);
return reflectValue;
} catch (Exception e) {
fail("Failed to reflect "+fieldNameValueToFetch);
}
return null;
}
// find a field in the class tree
public static Field reflectField(Class<?> classToReflect, String fieldNameValueToFetch) {
try {
Field reflectField = null;
Class<?> classForReflect = classToReflect;
do {
try {
reflectField = classForReflect.getDeclaredField(fieldNameValueToFetch);
} catch (NoSuchFieldException e) {
classForReflect = classForReflect.getSuperclass();
}
} while (reflectField==null || classForReflect==null);
reflectField.setAccessible(true);
return reflectField;
} catch (Exception e) {
fail("Failed to reflect "+fieldNameValueToFetch +" from "+ classToReflect);
}
return null;
}
// set a value with no setter
public static void refectSetValue(Object objToReflect, String fieldNameToSet, Object valueToSet) {
try {
Field reflectField = reflectField(objToReflect.getClass(), fieldNameToSet);
reflectField.set(objToReflect, valueToSet);
} catch (Exception e) {
fail("Failed to reflectively set "+ fieldNameToSet +"="+ valueToSet);
}
}
}
Then I can test the class with a private variable like this. This is useful for mocking deep in class trees that you have no control as well.
@Test
public void testWithRectiveMock() throws Exception {
// mock the base class using Mockito
ClassToMock mock = Mockito.mock(ClassToMock.class);
TestUtils.refectSetValue(mock, "privateVariable", "newValue");
// and this does not prevent normal mocking
Mockito.when(mock.somthingElse()).thenReturn("anotherThing");
// ... then do your asserts
}
I modified my code from my actual project here, in page. There could be a compile issue or two. I think you get the general idea. Feel free to grab the code and use it if you find it useful.
flatMap()
also takes advantage of partial lazy evaluation of streams. It will read the fist stream and only when required, will go to the next stream. The behaviour is explained in detail here: Is flatMap guaranteed to be lazy?
Keep the jar files under web-inf lib incase you included jar and it is not able to identify .
It worked in my case where everything was ok but it was not able to load the driver class.
For anyone else having the same problem, I figured it out myself.
<html>_x000D_
<body>_x000D_
<form target="_blank" action="https://website.com/action.php" method="POST">_x000D_
<input type="hidden" name="fullname" value="Sam" />_x000D_
<input type="hidden" name="city" value="Dubai " />_x000D_
<input onclick="window.location.href = 'https://website.com/my-account';" type="submit" value="Submit request" />_x000D_
</form>_x000D_
</body>_x000D_
</html>
_x000D_
All I had to do was add the target="_blank" attribute to inline on form to open the response in a new page and redirect the other page using onclick on the submit button.
Use org.apache.commons.lang3.StringUtils
String emptyString = new String();
result = StringUtils.defaultIfEmpty(emptyString, "default");
System.out.println(result);
String nullString = null;
result = StringUtils.defaultIfEmpty(nullString, "default");
System.out.println(result);
Both of the above options will print:
default
default
Your code should read -
String kk = wd.findElement(By.cssSelector("div[id^='customSelect'] span.selectLabel")).getText();
Use CSS. it's much cleaner and easier.. Let me know if that solves your issue.
Your string example looks like the query string part of a GET. If so, note that HttpContext has some help for you
int numberOfArgs = HttpContext.Current.QueryString.Count;
For more of what you can do with QueryString, see NameValueCollection
rsync
transfers files as fast as it can over the network. For example, try using it to copy one large file that doesn't exist at all on the destination. That speed is the maximum speed rsync can transfer data. Compare it with the speed of scp
(for example). rsync
is even slower at raw transfer when the destination file exists, because both sides have to have a two-way chat about what parts of the file are changed, but pays for itself by identifying data that doesn't need to be transferred.
A simpler way to run rsync
in parallel would be to use parallel
. The command below would run up to 5 rsync
s in parallel, each one copying one directory. Be aware that the bottleneck might not be your network, but the speed of your CPUs and disks, and running things in parallel just makes them all slower, not faster.
run_rsync() {
# e.g. copies /main/files/blah to /main/filesTest/blah
rsync -av "$1" "/main/filesTest/${1#/main/files/}"
}
export -f run_rsync
parallel -j5 run_rsync ::: /main/files/*
Solution for Windows:
You are not able to view your website, mainly because your firewall ( default OS firewall or Antivirus firewall ) is preventing incoming connections.
On Windows Firewall:
To allow incoming connections on specific ports, go to:
Control Panel > Windows Defender Firewall > Advanced Settings > Right Click Inbound Rules > Add New Rule.
Then :
- Select "Port" radio button.
- Enter the specific port / range you on which you want to enable incoming connections ( the port on which your server is running )
- Select "Allow the connection" radio button.
- Click Next ( unless you want to change the defaults )
- Give your rule a name and click Finish.
Note:
If you are using an Antivirus having a firewall, then the above steps will not work since the Antivirus would have disabled Windows firewall and instead runs its own firewall.
In that case, depending on the Antivirus program, go to your Antivirus's Firewall settings and open the port.
And now there is a better way.
OpenXML SDK for JavaScript.
You are better off using dependency injection:
public class Globals {
public int a;
public int b;
}
public class UsesGlobals {
private final Globals globals;
public UsesGlobals(Globals globals) {
this.globals = globals;
}
}
mvn install "-Dsomeproperty=propety value"
In pom.xml:
<properties>
<someproperty> ${someproperty} </someproperty>
</properties>

This behaviour is now part of the component lifecycle.
A component can implement the ngOnChanges method in the OnChanges interface to get access to input changes.
Example:
import {Component, Input, OnChanges} from 'angular2/core';
@Component({
selector: 'hero-comp',
templateUrl: 'app/components/hero-comp/hero-comp.html',
styleUrls: ['app/components/hero-comp/hero-comp.css'],
providers: [],
directives: [],
pipes: [],
inputs:['hero', 'real']
})
export class HeroComp implements OnChanges{
@Input() hero:Hero;
@Input() real:string;
constructor() {
}
ngOnChanges(changes) {
console.log(changes);
}
}
Use .net:
[System.IO.Path]::GetFileName("c:\foo.txt")
returns foo.txt
.
[System.IO.Path]::GetFileNameWithoutExtension("c:\foo.txt")
returns foo
It is perfectly fine if you want to go with the display: table-cell
solution. But instead of hacking it out, we have a better way to accomplish the same using display: flex;
. flex
is something which has a decent support.
.wrap {_x000D_
height: 200px;_x000D_
width: 200px;_x000D_
border: 1px solid #aaa;_x000D_
margin: 10px;_x000D_
display: flex;_x000D_
}_x000D_
_x000D_
.wrap span {_x000D_
align-self: flex-end;_x000D_
}
_x000D_
<div class="wrap">_x000D_
<span>Align me to the bottom</span>_x000D_
</div>
_x000D_
In the above example, we first set the parent element to display: flex;
and later, we use align-self
to flex-end
. This helps you push the item to the end of the flex
parent.
flex
)If you want to align the text to the bottom, you don't have to write so many properties for that, using display: table-cell;
with vertical-align: bottom;
is enough
div {_x000D_
display: table-cell;_x000D_
vertical-align: bottom;_x000D_
border: 1px solid #f00;_x000D_
height: 100px;_x000D_
width: 100px;_x000D_
}
_x000D_
<div>Hello</div>
_x000D_
Adding to above answers, I shall tell using example of an app I released on playstore.
This was the first app I developed when learning android there fore I worked only with activities There are multiple activity pages I think about 12. Most of these had content that could be reused in other pages yet I ended up with a separate activity page for almost every single click on the app. Once I learnt fragments I realised how all reusables could just be implemented and separate fragments and just be used with very few activities. My user may not see any difference, but the same can be done with lesser code besides fragments are light weight, apart from the reusability and modularity they offer.
SELECT substring(convert (varchar(23),Dateadd(s,10000,LEFT(getdate(),11)),121),12,8)

UIColor * background = [[UIColor alloc] initWithPatternImage:
[UIImage imageNamed:@"anImage.png"]];
self.view.backgroundColor = background;
[background release];
You can use getnameinfo
for Windows and for Linux.
Assuming you have a good (i.e. it's members have appropriate values) sockaddr*
called pSockaddr
:
char clienthost[NI_MAXHOST]; //The clienthost will hold the IP address.
char clientservice[NI_MAXSERV];
int theErrorCode = getnameinfo(pSockaddr, sizeof(*pSockaddr), clienthost, sizeof(clienthost), clientservice, sizeof(clientservice), NI_NUMERICHOST|NI_NUMERICSERV);
if( theErrorCode != 0 )
{
//There was an error.
cout << gai_strerror(e1) << endl;
}else{
//Print the info.
cout << "The ip address is = " << clienthost << endl;
cout << "The clientservice = " << clientservice << endl;
}

There is no explicit way to change the favicon globally using CSS that I know of. But you can use a simple trick to change it on the fly.
First just name, or rename, the favicon to "favicon.ico" or something similar that will be easy to remember, or is relevant for the site you're working on. Then add the link to the favicon in the head as you usually would. Then when you drop in a new favicon just make sure it's in the same directory as the old one, and that it has the same name, and there you go!
It's not a very elegant solution, and it requires some effort. But dropping in a new favicon in one place is far easier than doing a find and replace of all the links, or worse, changing them manually. At least this way doesn't involve messing with the code.
Of course dropping in a new favicon with the same name will delete the old one, so make sure to backup the old favicon in case of disaster, or if you ever want to go back to the old design.
I've been looking for an easy to use tool for this type of testing for a while now. I just came across this the other day: Network Delay Simulator
If you're running Windows, you should check it out. It was super easy to set up and get going, and seems to work really well. It allows you to define bandwidth, latency, and packet loss in each direction. The other really nice thing is that you can define "Flow Match Conditions" so that it only affects the traffic you want it to. Oh yeah, and it's free.
Well to obtain all different values in a Dataframe
you can use distinct. As you can see in the documentation that method returns another DataFrame
. After that you can create a UDF
in order to transform each record.
For example:
val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")
// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct
// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)
// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))
I have been searching for this same answer all morning and have pretty much found out that it's probably impossible to verify if every email address you ever need to check actually exists at the time you need to verify it. So as a work around, I kind of created a simple PHP
script to verify that the email address is formatted correct and it also verifies that the domain name used is correct as well.

That's a problem related to BOM (Byte Order Mark) character. Byte Order Mark BOM is an Unicode character used for defining a text file byte order and comes in the start of the file. Eclipse doesn't allow this character at the start of your file, so you must delete it. for this purpose, use a rich text editor like Notepad++ and save the file with encoding "UTF-8 without BOM". That should remove the problem.
I have copy pasted the some content from a website to a Notepad++ editor,
it shows the "LS" with black background. Have deleted the "LS" content and
have copy the same content from notepad++ to java file, it works fine.
If the problem allows it, try with EXISTS, since it's optimized to end as soon as a result is found (And don't buffer any response), so, if you are just trying to normalize data for a WHERE clause like this
SELECT FROM SOMETHING S WHERE S.ID IN ( SELECT DISTINCT DCR.SOMETHING_ID FROM DIFF_CARDINALITY_RELATIONSHIP DCR ) -- to keep same cardinality
A faster response would be:
SELECT FROM SOMETHING S WHERE EXISTS ( SELECT 1 FROM DIFF_CARDINALITY_RELATIONSHIP DCR WHERE DCR.SOMETHING_ID = S.ID )
This isn't always possible but when available you will see a faster response.
Maybe the most intuitive solution is probably to use the stringr
function str_remove
which is even easier than str_replace
as it has only 1 argument instead of 2.
The only tricky part in your example is that you want to keep the underscore but its possible: You must match the regular expression until it finds the specified string pattern (?=pattern)
.
See example:
strings = c("TGAS_1121", "MGAS_1432", "ATGAS_1121")
strings %>% stringr::str_remove(".+?(?=_)")
[1] "_1121" "_1432" "_1121"
A quick look through the documentation on regular expression sytanx should bring up ways to tell if it contains a lower/upper case character at some point.
A pool of threads means that all your threads are running, all the time – in other words, the thread function never returns. To give the threads something meaningful to do, you have to design a system of inter-thread communication, both for the purpose of telling the thread that there's something to do, as well as for communicating the actual work data.
Typically this will involve some kind of concurrent data structure, and each thread would presumably sleep on some kind of condition variable, which would be notified when there's work to do. Upon receiving the notification, one or several of the threads wake up, recover a task from the concurrent data structure, process it, and store the result in an analogous fashion.
The thread would then go on to check whether there's even more work to do, and if not go back to sleep.
The upshot is that you have to design all this yourself, since there isn't a natural notion of "work" that's universally applicable. It's quite a bit of work, and there are some subtle issues you have to get right. (You can program in Go if you like a system which takes care of thread management for you behind the scenes.)

ERRORLEVEL
will contain the return code of the last command. Sadly you can only check >=
for it.
Note specifically this line in the MSDN documentation for the If
statement:
errorlevel Number
Specifies a true condition only if the previous program run by Cmd.exe returned an exit code equal to or greater than Number.
So to check for 0 you need to think outside the box:
IF ERRORLEVEL 1 GOTO errorHandling
REM no error here, errolevel == 0
:errorHandling
Or if you want to code error handling first:
IF NOT ERRORLEVEL 1 GOTO no_error
REM errorhandling, errorlevel >= 1
:no_error

Shouldn't you have:
DELETE FROM tableA WHERE entitynum IN (...your select...)
Now you just have a WHERE with no comparison:
DELETE FROM tableA WHERE (...your select...)
So your final query would look like this;
DELETE FROM tableA WHERE entitynum IN (
SELECT tableA.entitynum FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum)
WHERE (LENGTH(q.memotext) NOT IN (8,9,10) OR q.memotext NOT LIKE '%/%/%')

Create a color.xml
file in the values folder:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="textbody">#ffcc33</color>

Then in any XML file, you can set color for text using,
android:textColor="@color/textbody"
Or you can use this color in a Java file:
final TextView tvchange12 = (TextView) findViewById(R.id.textView2);
//Set color for textbody from color.xml file
tvchange1.setTextColor(getResources().getColor(R.color.textbody));

Summary of all answers (Advantages & Disadvantages)
For single recyclerview
you can use it inside Coordinator layout.
Advantage - it will not load entire recyclerview items. So smooth loading.
Disadvantage - you can't load two recyclerview inside Coordinator layout - it produce scrolling problems
reference - https://stackoverflow.com/a/33143512/3879847
For multiple recylerview with minimum rows
you can load inside NestedScrollView
Advantage - it will scroll smoothly
Disadvantage - It load all rows of recyclerview so your activity open with delay
reference - https://stackoverflow.com/a/33143512/3879847
For multiple recylerview with large rows(more than 100)
You must go with recyclerview.
Advantage - Scroll smoothly, load smoothly
Disadvantage - You need to write more code and logic
Load each recylerview inside main recyclerview with help of multi-viewholders
ex:
MainRecyclerview
-ChildRecyclerview1 (ViewHolder1) -ChildRecyclerview2 (ViewHolder2) -ChildRecyclerview3 (ViewHolder3) -Any other layout (ViewHolder4)
Reference for multi-viewHolder - https://stackoverflow.com/a/26245463/3879847
Whilst some of the answers are good, there is a major caveat.
The mysql queries may be prevented from being cached, but it won't prevent your underlying O.S caching disk accesses into memory. This can be a major slowdown for some queries especially if they need to pull data from spinning disks.
So whilst it's good to use the methods above, I would also try and test with a different set of data/range each time, that's likely not been pulled from disk into disk/memory cache.
Interfaces are not part of the ES6 but classes are.
If you really need them, you should look at TypeScript which support them.
On MacOS if you've installed python via Homebrew, change the line in /usr/local/opt/python/libexec/bin/pip
from
from pip.internal import main
to
from pip._internal import main
Or use this one liner: sed -i '' "s/from pip import main/from pip._internal import main/" /usr/local/opt/python/libexec/bin/pip
The issue is caused by the changes in pip version 10 moving internal namespace under main._internal
and the bin script put in place by homebrew still looking it from the old place (where it used to be in version 9). Issue and some discussion https://github.com/pypa/pip/issues/5240
In my experience, to use wmic
in a script, you need to get the nested quoting right:
wmic product where "name = 'Windows Azure Authoring Tools - v2.3'" call uninstall /nointeractive
quoting both the query and the name. But wmic will only uninstall things installed via windows installer.
I think documentation has a great explanation of else, continue
[...] it is executed when the loop terminates through exhaustion of the list (with for) or when the condition becomes false (with while), but not when the loop is terminated by a break statement."

Next, go to the project editor for your target, and in the General tab, look for the Linked Frameworks and Libraries section.
Click + and select UserNotifications.framework:
// iOS 12 support
if #available(iOS 12, *) {
UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound, .provisional, .providesAppNotificationSettings, .criticalAlert]){ (granted, error) in }
application.registerForRemoteNotifications()
}
// iOS 10 support
if #available(iOS 10, *) {
UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]){ (granted, error) in }
application.registerForRemoteNotifications()
}
// iOS 9 support
else if #available(iOS 9, *) {
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
}
// iOS 8 support
else if #available(iOS 8, *) {
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
}
// iOS 7 support
else {
application.registerForRemoteNotifications(matching: [.badge, .sound, .alert])
}
Use Notification delegate methods
// Called when APNs has assigned the device a unique token
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
// Convert token to string
let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
print("APNs device token: \(deviceTokenString)")
}
// Called when APNs failed to register the device for push notifications
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
// Print the error to console (you should alert the user that registration failed)
print("APNs registration failed: \(error)")
}
For receiving push notification
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
completionHandler(UIBackgroundFetchResult.noData)
}
Setting up push notifications is enabling the feature within Xcode 8 for your app. Simply go to the project editor for your target and then click on the Capabilities tab. Look for Push Notifications and toggle its value to ON.

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]
Don't use getApplicationContext()
on declaring dialouge
Always use this
or your activity.this
Provisioning files are located in:
/Users/${USER}/Library/MobileDevice/Provisioning Profiles/
Just remove the out-of-date files.
Sort and Lock Table is the only solution I have seen which does work on other browsers than IE. (although this "locked column css" might do the trick as well). Required code block below.

Generic Table Sort
Basic Concept: A table can be sorted by clicking on the title of any
column in the table, toggling between ascending and descending sorts.
Assumptions:
* The first row of the table contains column titles that are "clicked"
to sort the table
* The images 'desc.gif','asc.gif','none.gif','sorting.gif' exist
* The img tag is in each column of the the title row to represent the
sort graphic.
* The CSS classes 'alternateRow' and 'sortedColumn' exist so we can
have alternating colors for each row and a highlight the sorted
column. Something like the <style> definition below, but with the
background colors set to whatever you want.
<style>
tr.alternateRow {
background-color: #E0F1E0;
}
td.sortedColumn {
background-color: #E0F1E0;
}
tr.alternateRow td.sortedColumn {
background-color: #c5e5c5;
}
</style>

Since WooCommerce 2.2
you are able to simply use the wc_get_product
Method. As an argument you can pass the ID
or simply leave it empty if you're already in the loop.
wc_get_product()->get_id();
OR with 2 lines
$product = wc_get_product();
$id = $product->get_id();
In my case, I was adding to a non existing element, or, I was adding bindings to an element that maybe exists, but it's parent did not. Similar to this:
var segDiv = $("#segments"); //did not exist, wrong id
var theDiv = segDiv.html("<div></div>");
ko.applyBindings(someVM, theDiv);
As far as I can tell, this error seems a bit overloaded in the sense that it will fire on a lot of different errors that can happen with the element, like it not existing. As such, the error description can be highly deceptive. It should have probably read:
"Failure to bind bindings to element. Possible reasons include: multiple binding attempts, element not existing, element not in DOM hierarchy, quirks in browsers, etc"
i have same this because in httpd.conf in apache PHPIniDir D:/wamp/bin/php/php5.5.12
that was incorrect
Another way to get only the numbers in a regex string is as shown below:
$output = preg_replace("/\D+/", "", $input);
It is important to read the HTML specifications to truly understand what behavior is to be expected:
The HTML5 spec explicitly states what happens in implicit submissions

A form element's default button is the first submit button in tree order whose form owner is that form element.
If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.
This was not made explicit in the HTML4 spec, however browsers have already been implementing what is described in the HTML5 spec (which is why it's included explicitly).
Edit to add:
The simplest answer I can think of is to put your submit button as the first [type="submit"]
item in the form, add padding to the bottom of the form with css, and absolutely position the submit button at the bottom where you'd like it.
I had the same issue on a brand new Windows 10 machine. My setup:
But I couldn't build .NET 4.0 projects:
Die Aufgabe konnte "AL.exe" mit dem SdkToolsPath-Wert "" oder dem Registrierungsschlüssel "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v8.0A\WinSDK-NetFx40Tools-x86
Solution: After trying (and failing) to install the Windows 7 SDK (because thats also includes the .NET 4.0 SDK) I needed to install the Windows 8 SDK and make sure the ".NET Framework 4.5 SDK" is installed.
It's crazy... but worked.
If java command is working and getting problem with javac. then first check in jdk's bin directory javac.exe file is there or not.
If javac.exe file is exist then set JAVA_HOME
as System variable.
Simply call list
on the generator.
lst = list(gen)
lst
Be aware that this affects the generator which will not return any further items.
You also cannot directly call list
in IPython, as it conflicts with a command for listing lines of code.
Tested on this file:
def gen():
yield 1
yield 2
yield 3
yield 4
yield 5
import ipdb
ipdb.set_trace()
g1 = gen()
text = "aha" + "bebe"
mylst = range(10, 20)
which when run:
$ python code.py
> /home/javl/sandbox/so/debug/code.py(10)<module>()
9
---> 10 g1 = gen()
11
ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
11
---> 12 text = "aha" + "bebe"
13
ipdb> lst = list(g1)
ipdb> lst
[1, 2, 3, 4, 5]
ipdb> q
Exiting Debugger.
There are debugger commands p
and pp
that will print
and prettyprint
any expression following them.
So you could use it as follows:
$ python code.py
> /home/javl/sandbox/so/debug/code.py(10)<module>()
9
---> 10 g1 = gen()
11
ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
11
---> 12 text = "aha" + "bebe"
13
ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c
There is also an exec
command, called by prefixing your expression with !
, which forces debugger to take your expression as Python one.
ipdb> !list(g1)
[]
For more details see help p
, help pp
and help exec
when in debugger.
ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the
command with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']
There's no need to build an array. You can address the DOM directly.
Try :
rows.hide();
$.each(data, function(i, v){
rows.filter(":contains('" + v + "')").show();
});
To discover the qualifying rows without displaying them immediately, then pass them to a function :
$("#searchInput").keyup(function() {
var rows = $("#fbody").find("tr").hide();
var data = this.value.split(" ");
var _rows = $();//an empty jQuery collection
$.each(data, function(i, v) {
_rows.add(rows.filter(":contains('" + v + "')");
});
myFunction(_rows);
});
UIImage Extension Swift 5
extension UIImage {
func resize(_ width: CGFloat, _ height:CGFloat) -> UIImage? {
let widthRatio = width / size.width
let heightRatio = height / size.height
let ratio = widthRatio > heightRatio ? heightRatio : widthRatio
let newSize = CGSize(width: size.width * ratio, height: size.height * ratio)
let rect = CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height)
UIGraphicsBeginImageContextWithOptions(newSize, false, 1.0)
self.draw(in: rect)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return newImage
}
}
Use : UIImage().resize(200, 300)
If you pass jQuery a function, it will not run until the page has loaded:
<script type="text/javascript">
$(function() {
//your header rotation code goes here
});
</script>
Starting in Python 2.6 there is a operator.methodcaller function.
So you can get something more elegant (and fast):
from operator import methodcaller
map(methodcaller('method_name'), list_of_objects)
According to HTML5 drafts, the checked
attribute is a “boolean attribute”, and “The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.” It is the name of the attribute that matters, and suffices. Thus, to make a checkbox initially checked, you use
<input type=checkbox checked>
By default, in the absence of the checked
attribute, a checkbox is initially unchecked:
<input type=checkbox>
Keeping things this way keeps them simple, but if you need to conform to XML syntax (i.e. to use HTML5 in XHTML linearization), you cannot use an attribute name alone. Then the allowed (as per HTML5 drafts) values are the empty string and the string checked
, case insensitively. Example:
<input type="checkbox" checked="checked" />
import datetime
d1 = datetime.date(2008,8,15)
d2 = datetime.date(2008,9,15)
diff = d2 - d1
for i in range(diff.days + 1):
print (d1 + datetime.timedelta(i)).isoformat()

You could do it like this:
var anchors = document.getElementsByTagName('a');
var index_a = 0;
var uls = document.getElementsByTagName('UL');
window.onload=function() {alert(anchors.length);};
for(var i=0 ; i<uls.length; i++)
{
lis = uls[i].getElementsByTagName('LI');
for(var j=0 ;j<lis.length;j++)
{
var first = lis[j].innerHTML;
string = "<img src=\"http://g.etfv.co/" + anchors[index_a++] +
"\" width=\"32\"
height=\"32\" /> " + first;
lis[j].innerHTML = string;
}
}
It's probably slightly more efficient to catch a NullPointerException. The above methods mean that the runtime is checking for null pointers twice.
def lensort(list_1):
list_2=[];list_3=[]
for i in list_1:
list_2.append([i,len(i)])
list_2.sort(key = lambda x : x[1])
for i in list_2:
list_3.append(i[0])
return list_3
This works for me!
This may not be a popular solution for everyone, but I like the Application Framework in Visual Basic, even when using C#.
Add a reference to Microsoft.VisualBasic
Create a class called WindowsFormsApplication
public class WindowsFormsApplication : WindowsFormsApplicationBase
{
/// <summary>
/// Runs the specified mainForm in this application context.
/// </summary>
/// <param name="mainForm">Form that is run.</param>
public virtual void Run(Form mainForm)
{
// set up the main form.
this.MainForm = mainForm;
// Example code
((Form1)mainForm).FileName = this.CommandLineArgs[0];
// then, run the the main form.
this.Run(this.CommandLineArgs);
}
/// <summary>
/// Runs this.MainForm in this application context. Converts the command
/// line arguments correctly for the base this.Run method.
/// </summary>
/// <param name="commandLineArgs">Command line collection.</param>
private void Run(ReadOnlyCollection<string> commandLineArgs)
{
// convert the Collection<string> to string[], so that it can be used
// in the Run method.
ArrayList list = new ArrayList(commandLineArgs);
string[] commandLine = (string[])list.ToArray(typeof(string));
this.Run(commandLine);
}
}
Modify your Main() routine to look like this
static class Program
{
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
var application = new WindowsFormsApplication();
application.Run(new Form1());
}
}
This method offers some additional usefull features (like SplashScreen support and some usefull events)
public event NetworkAvailableEventHandler NetworkAvailabilityChanged;d.
public event ShutdownEventHandler Shutdown;
public event StartupEventHandler Startup;
public event StartupNextInstanceEventHandler StartupNextInstance;
public event UnhandledExceptionEventHandler UnhandledException;
If you want to pass a Uri to another activity, try the method intent.setData(Uri uri) https://developer.android.com/reference/android/content/Intent.html#setData(android.net.Uri)
In another activity, via intent.getData() to obtain the Uri.
As of jQuery 1.7, .on()
is now the preferred method of binding events, rather than .bind()
:
From http://api.jquery.com/bind/:
As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements. Handlers are attached to the currently selected elements in the jQuery object, so those elements must exist at the point the call to .bind() occurs. For more flexible event binding, see the discussion of event delegation in .on() or .delegate().
The documentation page is located at http://api.jquery.com/on/
Infinity is a reserved character in HTML. Following are its values in various forms.
To use in html code
<p>The html symbol is ∞ </p>_x000D_
<p>The html symbol is ∞ </p>_x000D_
<p>The html symbol is ∞ </p>
_x000D_

They're just trawling lists of web sites, and recording the resulting IP addresses in a database.
All you're seeing is the reverse mapping of that list. It's not guaranteed to be a full list (indeed more often than not it won't be) because it's impossible to learn every possible web site address.
forEach()
can be implemented to be faster than for-each loop, because the iterable knows the best way to iterate its elements, as opposed to the standard iterator way. So the difference is loop internally or loop externally.
For example ArrayList.forEach(action)
may be simply implemented as
for(int i=0; i<size; i++)
action.accept(elements[i])
as opposed to the for-each loop which requires a lot of scaffolding
Iterator iter = list.iterator();
while(iter.hasNext())
Object next = iter.next();
do something with `next`
However, we also need to account for two overhead costs by using forEach()
, one is making the lambda object, the other is invoking the lambda method. They are probably not significant.
see also http://journal.stuffwithstuff.com/2013/01/13/iteration-inside-and-out/ for comparing internal/external iterations for different use cases.

Both the mongod (database server) and mongo (database client shell) programs are command line programs and each expects to be run in its own command line session. So, after starting the server (as you did with "./mongod") you should open a second command line session and run "./mongo" in it to give you a command line shell for talking to the server.
Didn't see any answers correctly using DATE_ADD
or DATE_SUB
:
Subtract 1 day from NOW()
...WHERE DATE_FIELD >= DATE_SUB(NOW(), INTERVAL 1 DAY)
Add 1 day from NOW()
...WHERE DATE_FIELD >= DATE_ADD(NOW(), INTERVAL 1 DAY)
I extended tarulen's answer to work with any number of arrays. It also should work with non-integer values.
function intersect() {
const last = arguments.length - 1;
var seen={};
var result=[];
for (var i = 0; i < last; i++) {
for (var j = 0; j < arguments[i].length; j++) {
if (seen[arguments[i][j]]) {
seen[arguments[i][j]] += 1;
}
else if (!i) {
seen[arguments[i][j]] = 1;
}
}
}
for (var i = 0; i < arguments[last].length; i++) {
if ( seen[arguments[last][i]] === last)
result.push(arguments[last][i]);
}
return result;
}
Use the +=
assignment operator:
for (var i = 0; i < myVar.length; i += 3) {
Technically, you can place any expression you'd like in the final expression of the for loop, but it is typically used to update the counter variable.
For more information about each step of the for loop, check out the MDN article.
The source for this answer is the comment to the answer at: Will docker container auto sync time with the host machine?
After looking at the answer, I realized that there is no way a clock drift will occur on the docker container. Docker uses the same clock as the host and the docker cannot change it. It means that doing an ntpdate
inside the docker does not work.
The correct thing to do is to update the host time using ntpdate
As far as syncing timezones is concerned, -v /etc/localtime:/etc/localtime:ro
works.

Do not depend on ADB shell, just treat it (the adb logcat) a normal linux output and then pip it:
$ adb shell logcat | grep YouTag

This question keeps coming up and I did not find a satisfying result yet, so here is what worked for me (based on a previous answer https://stackoverflow.com/a/52706362/1806760, which is not working):
My server is https://gitlab.dev
with a self-signed certificate.

I was facing the same problem, without using scale_y_continuous
nor coord_cartesian
.
The conflict was coming from the x axis, where I defined limits = c(1, 30)
. It seems such limits do not provide enough space if you want to "dodge" your bars, so R still throws the error
Removed 8 rows containing missing values (geom_bar)
Adjusting the limits of the x axis to limits = c(0, 31)
solved the problem.
In conclusion, even if you are not putting limits to your y axis, check out your x axis' behavior to ensure you have enough space
First Add a Class called Win32.cs
public class Win32
{
[DllImport("User32.Dll")]
public static extern long SetCursorPos(int x, int y);
[DllImport("User32.Dll")]
public static extern bool ClientToScreen(IntPtr hWnd, ref POINT point);
[StructLayout(LayoutKind.Sequential)]
public struct POINT
{
public int x;
public int y;
public POINT(int X, int Y)
{
x = X;
y = Y;
}
}
}
You can use it then like this:
Win32.POINT p = new Win32.POINT(xPos, yPos);
Win32.ClientToScreen(this.Handle, ref p);
Win32.SetCursorPos(p.x, p.y);
Yeah, IsNumeric is VB. Usually people use the TryParse() method, though it is a bit clunky. As you suggested, you can always write your own.
int i;
if (int.TryParse(string, out i))
{
}
It's working for me:
<%= image_tag( root_url + "images/rss.jpg", size: "50x50", :alt => "rss feed") -%>
You have to call the function you want to be called on load (i.e., load of the document/page). For example, the function you want to load when document or page load is called "yourFunction". This can be done by calling the function on load event of the document. Please see the code below for more detail.
Try the code below:
<script src="js/jquery-1.11.0.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
yourFunction();
});
function yourFunction(){
//some code
}
</script>
With newer versions of bundler you can use the clean task:
$ bundle help clean
Usage:
bundle clean
Options:
[--dry-run=only print out changes, do not actually clean gems]
[--force=forces clean even if --path is not set]
[--no-color=Disable colorization in output]
-V, [--verbose=Enable verbose output mode]
Cleans up unused gems in your bundler directory
$ bundle clean --dry-run --force
Would have removed actionmailer (3.1.12)
Would have removed actionmailer (3.2.0.rc2)
Would have removed actionpack (3.1.12)
Would have removed actionpack (3.2.0.rc2)
Would have removed activemodel (3.1.12)
...
edit:
This is not recommended if you're using a global gemset (i.e. - all of your projects keep their gems in the same place). There're few ways to keep each project's gems separate, though:
rvm
gemsets (http://rvm.io/gemsets/basics)bundle install
with any of the following options: --deployment
or --path=<path>
(http://bundler.io/v1.3/man/bundle-install.1.html)This is oddly confusing to me. I know it shouldn't be. To check my understanding, I'd like to use a family relations model to compare. Assuming "You" is the current webpage, is the following correct?
<img src="picture.jpg"> In your folder with you, like a sibling
<img src="images/picture.jpg"> In your child's folder, under you
<img src="../picture.jpg"> In your parent's folder, above you
<img src="/images/picture.jpg"> In your cousin's folder
So, up to parent, over to sibling, down to their child = your cousin, named "images".
You need to create a delegate type. The keyword 'delegate' in the anonymous method creation is a bit misleading. You are not creating an anonymous delegate but an anonymous method. The method you created can be used in a delegate. Like this:
myControl.Invoke(new MethodInvoker(delegate() { (MyMethod(this, new MyEventArgs(someParameter)); }));
Add multiple System.MailAdress object to get what you want.
That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:
DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87
Double check your table definition. Maybe you just missed adding something.
I also tried google-ing this problem and saw this:
http://www.coderanch.com/t/515475/JDBC/databases/sql-insert-statement-giving-sqlcode
remember password needs to be set further even after restarting mysql as below
SET PASSWORD = PASSWORD('root');
You can just use the pipe on its own:
"string1|string2"
for example:
String s = "string1, string2, string3";
System.out.println(s.replaceAll("string1|string2", "blah"));
Output:
blah, blah, string3
The main reason to use parentheses is to limit the scope of the alternatives:
String s = "string1, string2, string3";
System.out.println(s.replaceAll("string(1|2)", "blah"));
has the same output. but if you just do this:
String s = "string1, string2, string3";
System.out.println(s.replaceAll("string1|2", "blah"));
you get:
blah, stringblah, string3
because you've said "string1" or "2".
If you don't want to capture that part of the expression use ?:
:
String s = "string1, string2, string3";
System.out.println(s.replaceAll("string(?:1|2)", "blah"));
You want to use DATEADD, using a negative duration. e.g.
DATEADD(minute, -15, '2000-01-01 08:30:00')
In this code i is iterated till 3 then the loop ends;
int function (void)
{
for (int i=0; i<5; i++)
{
if (i == 3)
{
break;
}
}
}
In this code i is iterated till 3 but with an output;
int function (void)
{
for (int i=0; i<5; i++)
{
if (i == 3)
{
return i;
}
}
}
I had a similar problem and none of the solutions above worked, so I went with an old standby that always works:
That almost always works if you've spent 10 minutes at it and can't get it.
Note that for similar problems with older versions (2008, 2005) you can usually get away with just changing the version in the .csproj and either changing the version in the .sln or discarding it, but this doesn't seem to work for 2013.

git config user.name
git config user.email
I believe these are the commands you are looking for.
Here is where I found them: http://alvinalexander.com/git/git-show-change-username-email-address
public static void formatDouble(double myDouble){
NumberFormat numberFormatter = new DecimalFormat("##.000");
String result = numberFormatter.format(myDouble);
System.out.println(result);
}
For instance, if the double value passed into the formatDouble() method is 345.9372, the following will be the result: 345.937 Similarly, if the value .7697 is passed to the method, the following will be the result: .770

Edit your config file normally located at '~/.ssh/config', and at the beggining of the file, add the below lines
Host *
User your_login_user
StrictHostKeyChecking no
IdentityFile ~/my_path/id_rsa.pub
User set to your_login_user
says that this settings belongs to your_login_user
StrictHostKeyChecking set to no will avoid the prompt
IdentityFile is path to RSA key
This works for me and my scripts, good luck to you.
Why dont you show a generated Picture (screenshot) of the PDF?
Most people do not read the comments so to summarize (Thanks to @Industrial-antidepressant and @wrecker):
As suggested in a bug ticket you should try the following:
android-studio/plugins/gradle/lib
gradle-*-1.8
filesIt should work. Make sure to star the above bug ticket to get informed.
Little tip: Try the new compile setting Settings -> Compiler -> Gradle and activate the third in-process build for a speed up. Depending on your project setting you might want to select the first one as well. With that my project build time reduced to 2-4 seconds (before 20+ seconds).
The python interpreter compiles the *.py script file and saves the results of the compilation to the __pycache__
directory.
When the project is executed again, if the interpreter identifies that the *.py script has not been modified, it skips the compile step and runs the previously generated *.pyc file stored in the __pycache__
folder.
When the project is complex, you can make the preparation time before the project is run shorter. If the program is too small, you can ignore that by using python -B abc.py
with the B
option.
The provided answer is absolutely correct, but I wanted to expand for any future visitors who may want to do it a bit more dynamically -
In the view -
<div ng-repeat="person in persons">
<div ng-click="changeView(person)">
Go to edit
<div>
<div>
In the controller -
$scope.changeView = function(person){
var earl = '/editperson/' + person.id;
$location.path(earl);
}
Same basic concept as the accepted answer, just adding some dynamic content to it to improve a bit. If the accepted answer wants to add this I will delete my answer.
All you have to do is wrap your content inside a Grid Container tag, specify the spacing, then wrap the actual content inside a Grid Item tag.
<Grid container spacing={24}>
<Grid item xs={8}>
<leftHeaderContent/>
</Grid>
<Grid item xs={3}>
<rightHeaderContent/>
</Grid>
</Grid>
Also, I've struggled with material grid a lot, I suggest you checkout flexbox which is built into CSS automatically and you don't need any addition packages to use. Its very easy to learn.
The Difference
There are a few characters which can indicate a new line. The usual ones are these two:
* '\n' or '0x0A' (10 in decimal) -> This character is called "Line Feed" (LF).
* '\r' or '0x0D' (13 in decimal) -> This one is called "Carriage return" (CR).
Different Operating Systems handle newlines in a different way. Here is a short list of the most common ones:
* DOS and Windows
They expect a newline to be the combination of two characters, namely '\r\n' (or 13 followed by 10).
* Unix (and hence Linux as well)
Unix uses a single '\n' to indicate a new line.
* Mac
Macs use a single '\r'
.
Taken from Here
Try this out: alert(col.firstChild.data)
Check this out for the difference between nodeValue and data: When working with text nodes should I use the "data", "nodeValue", "textContent" or "wholeText" field?
List<String> entries;
private ArrayAdapter<String> categoryAdapter;
//Your list of entries {Example: <"category1","category2","category3">}
entries = new ArrayList<String>();
categoryAdapter = new ArrayAdapter<String>(ViewBeaconsActivity.this,
android.R.layout.simple_list_item_1, entries);
//Remove that specific category from the list
entries.remove(categoryName);
//Notify the adapter that your dataset has changed.
categoryAdapter.notifyDataSetChanged();
To move and delete specific records by selecting using WHERE query,
BEGIN TRANSACTION;
Insert Into A SELECT * FROM B where URL="" AND email ="" AND Annual_Sales_Vol="" And OPENED_In="" AND emp_count="" And contact_person= "" limit 0,2000;
delete from B where Id In (select Id from B where URL="" AND email ="" AND Annual_Sales_Vol="" And OPENED_In="" AND emp_count="" And contact_person= "" limit 0,2000);
commit;
Usually, you would also have a header file that you include in your code to access the symbols.
From the v3 documentation (Developer's Guide > Concepts > Developing for Mobile Devices):
Android and iOS devices respect the following
<meta>
tag:<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
This setting specifies that the map should be displayed full-screen and should not be resizable by the user. Note that the iPhone's Safari browser requires this
<meta>
tag be included within the page's<head>
element.

In case of float values with characters 'e' '+' it errors out if we try to convert in decimal. ('2.81104e+006'). It still pass ISNUMERIC test.
SELECT ISNUMERIC('2.81104e+006')
returns 1
.
SELECT convert(decimal(15,2), '2.81104e+006')
returns
error: Error converting data type varchar to numeric.
And
SELECT try_convert(decimal(15,2), '2.81104e+006')
returns NULL
.
SELECT convert(float, '2.81104e+006')
returns the correct value 2811040
.
The three dot (...) notation is actually borrowed from mathematics, and it means "...and so on".
As for its use in Java, it stands for varargs
, meaning that any number of arguments can be added to the method call. The only limitations are that the varargs
must be at the end of the method signature and there can only be one per method.
The res.json()
function should be sufficient for most cases.
app.get('/', (req, res) => res.json({ answer: 42 }));
The res.json()
function converts the parameter you pass to JSON using JSON.stringify()
and sets the Content-Type
header to application/json; charset=utf-8
so HTTP clients know to automatically parse the response.
If you are looking for a better code editor, vim comes with VisVim, a plugin to replace the VS code editor with vim.
ListView myListView = (ListView) rootView.findViewById(R.id.myListView);
ArrayList<String> myStringArray1 = new ArrayList<String>();
myStringArray1.add("something");
adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
myListView.setAdapter(adapter);
Try it like this
public OnClickListener moreListener = new OnClickListener() {
@Override
public void onClick(View v) {
adapter = null;
myStringArray1.add("Andrea");
adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
myListView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
};
Tips:
You can try to use
ctx.getSystemService("phone_msim")
instead of
ctx.getSystemService(Context.TELEPHONY_SERVICE)
If you have already tried Vaibhav's answer and telephony.getClass().getMethod()
fails, above is what works for my Qualcomm mobile.
Iterate through a copy of the list:
>>> a = ["a", "b", "c", "d", "e"]
>>> for item in a[:]:
print item
if item == "b":
a.remove(item)
a
b
c
d
e
>>> print a
['a', 'c', 'd', 'e']
I had this issue, and solved. This was due to the WHERE clause contains String value instead of integer value.
This is for using a single directory for multiple projects. I use this technique for some closely related projects where I often need to pull changes from one project into another. It's similar to the orphaned branches idea but the branches don't need to be orphaned. Simply start all the projects from the same empty directory state.
Don't expect wonders from this solution. As I see it, you are always going to have annoyances with untracked files. Git doesn't really have a clue what to do with them and so if there are intermediate files generated by a compiler and ignored by your .gitignore file, it is likely that they will be left hanging some of the time if you try rapidly swapping between - for example - your software project and a PH.D thesis project.
However here is the plan. Start as you ought to start any git projects, by committing the empty repository, and then start all your projects from the same empty directory state. That way you are certain that the two lots of files are fairly independent. Also, give your branches a proper name and don't lazily just use "master". Your projects need to be separate so give them appropriate names.
Git commits (and hence tags and branches) basically store the state of a directory and its subdirectories and Git has no idea whether these are parts of the same or different projects so really there is no problem for git storing different projects in the same repository. The problem is then for you clearing up the untracked files from one project when using another, or separating the projects later.
cd some_empty_directory
git init
touch .gitignore
git add .gitignore
git commit -m empty
git tag EMPTY
Start your projects from empty.
git branch software EMPTY
git checkout software
echo "array board[8,8] of piece" > chess.prog
git add chess.prog
git commit -m "chess program"
whenever you like.
git branch thesis EMPTY
git checkout thesis
echo "the meaning of meaning" > philosophy_doctorate.txt
git add philosophy_doctorate.txt
git commit -m "Ph.D"
Go back and forwards between projects whenever you like. This example goes back to the chess software project.
git checkout software
echo "while not end_of_game do make_move()" >> chess.prog
git add chess.prog
git commit -m "improved chess program"
You will however be annoyed by untracked files when swapping between projects/branches.
touch untracked_software_file.prog
git checkout thesis
ls
philosophy_doctorate.txt untracked_software_file.prog
Sort of by definition, git doesn't really know what to do with untracked files and it's up to you to deal with them. You can stop untracked files from being carried around from one branch to another as follows.
git checkout EMPTY
ls
untracked_software_file.prog
rm -r *
(directory is now really empty, apart from the repository stuff!)
git checkout thesis
ls
philosophy_doctorate.txt
By ensuring that the directory was empty before checking out our new project we made sure there were no hanging untracked files from another project.
$ GIT_AUTHOR_DATE='2001-01-01:T01:01:01' GIT_COMMITTER_DATE='2001-01-01T01:01:01' git commit -m empty
If the same dates are specified whenever committing an empty repository, then independently created empty repository commits can have the same SHA1 code. This allows two repositories to be created independently and then merged together into a single tree with a common root in one repository later.
# Create thesis repository.
# Merge existing chess repository branch into it
mkdir single_repo_for_thesis_and_chess
cd single_repo_for_thesis_and_chess
git init
touch .gitignore
git add .gitignore
GIT_AUTHOR_DATE='2001-01-01:T01:01:01' GIT_COMMITTER_DATE='2001-01-01:T01:01:01' git commit -m empty
git tag EMPTY
echo "the meaning of meaning" > thesis.txt
git add thesis.txt
git commit -m "Wrote my PH.D"
git branch -m master thesis
# It's as simple as this ...
git remote add chess ../chessrepository/.git
git fetch chess chess:chess
It may also help if you keep your projects in subdirectories where possible, e.g. instead of having files
chess.prog
philosophy_doctorate.txt
have
chess/chess.prog
thesis/philosophy_doctorate.txt
In this case your untracked software file will be chess/untracked_software_file.prog
. When working in the thesis
directory you should not be disturbed by untracked chess program files, and you may find occasions when you can work happily without deleting untracked files from other projects.
Also, if you want to remove untracked files from other projects, it will be quicker (and less prone to error) to dump an unwanted directory than to remove unwanted files by selecting each of them.
So you might want to name your branches something like
project1/master
project1/featureABC
project2/master
project2/featureXYZ
If anyone came to this question looking for ways to add multiple parameters at the same time (my case), you can use .params
with a MultivalueMap instead of adding each .param
:
LinkedMultiValueMap<String, String> requestParams = new LinkedMultiValueMap<>()
requestParams.add("id", "1");
requestParams.add("name", "john");
requestParams.add("age", "30");
mockMvc.perform(get("my/endpoint").params(requestParams)).andExpect(status().isOk())
EventLog.Log should be set as "Application"
-[NSString initWithData:encoding]
is your friend but only when you use a proper encoding.
Current answers are perfectly correct on how to create the aggregations, but none actually address the column alias/renaming that is also requested in the question.
Typically, this is how I handle this case:
val dimensionFields = List("col1")
val metrics = List("col2", "col3", "col4")
val columnOfInterests = dimensions ++ metrics
val df = spark.read.table("some_table").
.select(columnOfInterests.map(c => col(c)):_*)
.groupBy(dimensions.map(d => col(d)): _*)
.agg(metrics.map( m => m -> "sum").toMap)
.toDF(columnOfInterests:_*) // that's the interesting part
The last line essentially renames every columns of the aggregated dataframe to the original fields, essentially changing sum(col2)
and sum(col3)
to simply col2
and col3
.
Here is an appendTo version using the html dropdown you mentioned. It inserts another row on "change".
$('#dropdown').on( 'change', function(e) {
$('#table').append('<tr><td>COL1</td><td>COL2</td></tr>');
});
With an example for you to play with. Best of luck!
There is a specific example that "_" be used:
type StringMatcher = String => (String => Boolean)
def starts: StringMatcher = (prefix:String) => _ startsWith prefix
may be equal to :
def starts: StringMatcher = (prefix:String) => (s)=>s startsWith prefix
Applying “_” in some scenarios will automatically convert to “(x$n) => x$n ”
While I agree with the other answers regarding the RoleManager, I would advice to examine the possibility to implement Authorization through Claims (Expressing Roles as Claims).
Starting with the .NET Framework 4.5, Windows Identity Foundation (WIF) has been fully integrated into the .NET Framework.
In claims-aware applications, the role is expressed by a role claim type that should be available in the token. When the IsInRole() method is called, there is a check made to see if the current user has that role.
The role claim type is expressed using the following URI: "http://schemas.microsoft.com/ws/2008/06/identity/claims/role"
So instead of using the RoleManager, you can "add a user to a role" from the UserManager, doing something like this:
var um = new UserManager();
um.AddClaimAsync(1, new Claim("http://schemas.microsoft.com/ws/2008/06/identity/claims/role", "administrator"));
With the above lines you have added a role claim with the value "administrator" to the user with the id "1"...
Claims authorization, as suggested by MSFT, can simplify and increase the performance of authentication and authorization processes eliminating some back-end queries every time authorization takes place.
Using Claims you may not need the RoleStore anymore. (AspNetRoles, AspNetUserRoles)
If you are trying to run the macro from your personal workbook it might not work as opening an Excel file with a VBScript doesnt automatically open your PERSONAL.XLSB. you will need to do something like this:
Dim oFSO
Dim oShell, oExcel, oFile, oSheet
Set oFSO = CreateObject("Scripting.FileSystemObject")
Set oShell = CreateObject("WScript.Shell")
Set oExcel = CreateObject("Excel.Application")
Set wb2 = oExcel.Workbooks.Open("C:\..\PERSONAL.XLSB") 'Specify foldername here
oExcel.DisplayAlerts = False
For Each oFile In oFSO.GetFolder("C:\Location\").Files
If LCase(oFSO.GetExtensionName(oFile)) = "xlsx" Then
With oExcel.Workbooks.Open(oFile, 0, True, , , , True, , , , False, , False)
oExcel.Run wb2.Name & "!modForm"
For Each oSheet In .Worksheets
oSheet.SaveAs "C:\test\" & oFile.Name & "." & oSheet.Name & ".txt", 6
Next
.Close False, , False
End With
End If
Next
oExcel.Quit
oShell.Popup "Conversion complete", 10
So at the beginning of the loop it is opening personals.xlsb and running the macro from there for all the other workbooks. Just thought I should post in here just in case someone runs across this like I did but cant figure out why the macro is still not running.
Doing this fixed my issue
<script type="text/javascript">
function SubmitFrm(){
var Searchtxt = document.getElementById("txtSearch").value;
window.location = "http://www.mysite.com/search/?Query=" + Searchtxt;
}
</script>
I changed .value();
to .value;
taking out the ()
I did not change anything in my text field or submit button
<input name="txtSearch" type="text" id="txtSearch" class="field" />
<input type="submit" name="btnSearch" value="" id="btnSearch" class="btn" onclick="javascript:SubmitFrm()" />
Works like a charm.
On macOS, none of the answers worked for me. I discovered that was due to differences in how sed
works on macOS and other BSD systems compared to GNU.
In particular BSD sed
takes the -i
option but requires a suffix for the backup (but an empty suffix is permitted)
grep
version from this answer.
grep -rl 'foo' ./ | LC_ALL=C xargs sed -i '' 's/foo/bar/g'
find
version from this answer.
find . \( ! -regex '.*/\..*' \) -type f | LC_ALL=C xargs sed -i '' 's/foo/bar/g'
Don't omit the Regex to ignore .
folders if you're in a Git repo. I realized that the hard way!
That LC_ALL=C
option is to avoid getting sed: RE error: illegal byte sequence
if sed
finds a byte sequence that is not a valid UTF-8 character. That's another difference between BSD and GNU. Depending on the kind of files you are dealing with, you may not need it.
For some reason that is not clear to me, the grep
version found more occurrences than the find
one, which is why I recommend to use grep
.
You have to write your own compareTo() method that has the Java code needed to perform the comparison.
If we wanted for example to compare two public fields, campus, then faculty, we might do something like:
int compareTo(GraduationCeremony gc)
{
int c = this.campus.compareTo(gc.campus);
if( c != 0 )
{
//sort by campus if we can
return c;
}
else
{
//campus equal, so sort by faculty
return this.faculty.compareTo(gc.faculty);
}
}
This is simplified but hopefully gives you an idea. Consult the Comparable and Comparator docs for more info.
The problem it may cause if you do not synchronize before wait()
is as follows:
makeChangeOnX()
and checks the while condition, and it is true
(x.metCondition()
returns false
, means x.condition
is false
) so it will get inside it. Then just before the wait()
method, another thread goes to setConditionToTrue()
and sets the x.condition
to true
and notifyAll()
.wait()
method (not affected by the notifyAll()
that happened few moments before).
In this case, the 1st thread will stay waiting for another thread to perform setConditionToTrue()
, but that might not happen again.But if you put
synchronized
before the methods that change the object state, this will not happen.
class A {
private Object X;
makeChangeOnX(){
while (! x.getCondition()){
wait();
}
// Do the change
}
setConditionToTrue(){
x.condition = true;
notifyAll();
}
setConditionToFalse(){
x.condition = false;
notifyAll();
}
bool getCondition(){
return x.condition;
}
}

A servlet at its very core is a java class; which can handle HTTP requests. Typically the internal nitty-gritty of reading a HTTP request and response over the wire is taken care of by the containers like Tomcat. This is done so that as a server side developer you can focus on what to do with the HTTP request and responses and not bother about dealing with code that deals with networking etc. The container will take care of things like wrapping the whole thing in a HTTP response object and send it over to the client (say a browser).
Now the next logical question to ask is who decides what is a container supposed to do? And the answer is; In Java world at least It is guided (note I did not use the word controlled) by specifications. For example Servlet specifications (See resource 2) dictates what a servlet must be able to do. So if you can write an implementation for the specification, congratulations you just created a container (Technically containers like Tomcat also implement other specifications and do tricky stuff like custom class loaders etc but you get the idea).
Assuming you have a container, your servlets are now java classes whose lifecycle will be maintained by the container but their reaction to incoming HTTP requests will be decided by you. You do that by writing what-you-want-to-do in the pre-defined methods like init(), doGet(), doPost() etc. Look at Resource 3.
Here is a fun exercise for you. Create a simple servlet like in Resource 3 and write a few System.out.println() statements in it's constructor method (Yes you can have a constructor of a servlet), init(), doGet(), doPost() methods and run the servlet in tomcat. See the console logs and tomcat logs.
Hope this helps, happy learning.
Resources
Look how the HTTP servlet looks here(Tomcat example).
Servlet Specification.
Simple Servlet example.
Start reading the book online/PDF It also provides you download of the whole book. May be this will help. if you are just starting servlets may be it's a good idea to read the material along with the servlet API. it's a slower process of learning, but is way more helpful in getting the basics clear.
You should not add to your list using c
inside the loop, because that can result in very very slow code. Basically when you do c(l, new_element)
, the whole contents of the list are copied. Instead of that, you need to access the elements of the list by index. If you know how long your list is going to be, it's best to initialise it to this size using l <- vector("list", N)
. If you don't you can initialise it to have length equal to some large number (e.g if you have an upper bound on the number of iterations) and then just pick the non-NULL elements after the loop has finished. Anyway, the basic point is that you should have an index to keep track of the list element and add using that eg
i <- 1
while(...) {
l[[i]] <- new_element
i <- i + 1
}
For more info have a look at Patrick Burns' The R Inferno (Chapter 2).
file_name=test.log
# set first K lines:
K=1000
# line count (N):
N=$(wc -l < $file_name)
# length of the bottom file:
L=$(( $N - $K ))
# create the top of file:
head -n $K $file_name > top_$file_name
# create bottom of file:
tail -n $L $file_name > bottom_$file_name
Also, on second thought, split will work in your case, since the first split is larger than the second. Split puts the balance of the input into the last split, so
split -l 300000 file_name
will output xaa
with 300k lines and xab
with 100k lines, for an input with 400k lines.
To improve performance you could have a single predefined sting if you know the max length like:
String template = "####################################";
And then simply perform a substring once you know the length.
For things like this, you don't blindly keep clicking 'Next', 'Next', and 'I Agree'.
WAMP informs you about this during and before installation:

from this page:
I found this info:
The mod_fastcgi process manager isn't particularly patient though (there's room for improvement here) and since it has to shutdown too, sends a SIGTERM to all of the FastCGI applications it is responsible for. Apache will restart the process manager and it will restart its managed applications (as if the server was just started). SIGTERM is, well, SIGTERM - your application should exit quickly.
What this implies to me is that if Database I/O, or some other part of the CGI script, fails to respond in a timely fashion (ie getting slower with data-volume growth), that mod_fastcgi is killing the script......is that how other people interpret these docs or what am I missing..
The comma got eaten by the quotes!
This part:
("username," visitorName);
Should be this:
("username", visitorName);
Aside: For pasting code into the console, you can paste them in one line at a time to help you pinpoint where things went wrong ;-)
The binary representation is the key. An Example: Unsigned int in HEX
0XFFFFFFF = translates to = 1111 1111 1111 1111 1111 1111 1111 1111
Which represents 4,294,967,295
in a base-ten positive number.
But we also need a way to represent negative numbers.
So the brains decided on twos complement.
In short, they took the leftmost bit and decided that when it is a 1 (followed by at least one other bit set to one) the number will be negative.
And the leftmost bit is set to 0 the number is positive.
Now let's look at what happens
0000 0000 0000 0000 0000 0000 0000 0011 = 3
Adding to the number we finally reach.
0111 1111 1111 1111 1111 1111 1111 1111 = 2,147,483,645
the highest positive number with a signed integer. Let's add 1 more bit (binary addition carries the overflow to the left, in this case, all bits are set to one, so we land on the leftmost bit)
1111 1111 1111 1111 1111 1111 1111 1111 = -1
So I guess in short we could say the difference is the one allows for negative numbers the other does not. Because of the sign bit or leftmost bit or most significant bit.
Original answer using git's start-ssh-agent
Make sure you have Git installed and have git's cmd
folder in your PATH. For example, on my computer the path to git's cmd folder is C:\Program Files\Git\cmd
Make sure your id_rsa
file is in the folder c:\users\yourusername\.ssh
Restart your command prompt if you haven't already, and then run start-ssh-agent
. It will find your id_rsa
and prompt you for the passphrase
Update 2019 - A better solution if you're using Windows 10: OpenSSH is available as part of Windows 10 which makes using SSH from cmd/powershell much easier in my opinion. It also doesn't rely on having git installed, unlike my previous solution.
Open Manage optional features
from the start menu and make sure you have Open SSH Client
in the list. If not, you should be able to add it.
Open Services
from the start Menu
Scroll down to OpenSSH Authentication Agent
> right click > properties
Change the Startup type from Disabled to any of the other 3 options. I have mine set to Automatic (Delayed Start)
Open cmd and type where ssh
to confirm that the top listed path is in System32. Mine is installed at C:\Windows\System32\OpenSSH\ssh.exe
. If it's not in the list you may need to close and reopen cmd.
Once you've followed these steps, ssh-agent, ssh-add and all other ssh commands should now work from cmd. To start the agent you can simply type ssh-agent
.
GIT_SSH
environment variable to the output of where ssh
which you ran before (e.g C:\Windows\System32\OpenSSH\ssh.exe
). This is to stop inconsistencies between the version of ssh you're using (and your keys are added/generated with) and the version that git uses internally. This should prevent issues that are similar to thisSome nice things about this solution:
id_rsa
Hope this helps
If you are using Jackson, then you can use the @JsonProperty
annotation to customize the name of a given JSON property.
Therefore, you just have to annotate the entity fields with the @JsonProperty
annotation and provide a custom JSON property name, like this:
@Entity
public class City {
@Id
@JsonProperty("value")
private Long id;
@JsonProperty("label")
private String name;
//Getters and setters omitted for brevity
}
JSON-B is the standard binding layer for converting Java objects to and from JSON. If you are using JSON-B, then you can override the JSON property name via the @JsonbProperty
annotation:
@Entity
public class City {
@Id
@JsonbProperty("value")
private Long id;
@JsonbProperty("label")
private String name;
//Getters and setters omitted for brevity
}
How about a workaround?
In my case I took the value of the textarea in a jQuery variable, and changed all "<p> "
to <p class="clear">
and clear class to have certain height and margin, as the following example:
jQuery
tinyMCE.triggerSave();
var val = $('textarea').val();
val = val.replace(/<p> /g, '<p class="clear">');
the val is then saved to the database with the new val.
CSS
p.clear{height: 2px; margin-bottom: 3px;}
You can adjust the height & margin as you wish. And since 'p' is a display: block element. it should give you the expected output.
Hope that helps!
In your case I use: val dm = ListBuffer[String]()
and val dk = ListBuffer[Map[String,anyRef]]()
One option is to put the character literally in your script, e.g.:
const omega = 'O';
This requires that you let the browser know the correct source encoding, see Unicode in JavaScript
However, if you can't or don't want to do this (e.g. because the character is too exotic and can't be expected to be available in the code editor font), the safest option may be to use new-style string escape or String.fromCodePoint
:
const omega = '\u{3a9}';
// or:
const omega = String.fromCodePoint(0x3a9);
This is not restricted to UTF-16 but works for all unicode code points. In comparison, the other approaches mentioned here have the following downsides:
const omega = 'Ω';
): only work when rendered unescaped in an HTML elementconst omega = '\u03A9';
): restricted to UTF-16String.fromCharCode
: restricted to UTF-16When clicking on the button for search you can find it without a loop.
Just add to the option an attribute with the value you need (like id
) and search for it specific.
$('#search_wrapper button').on('click', function(){
console.log($('option[value="'+
$('#autocomplete_input').val() +'"]').data('value'));
})

Something like:
var min = dates.reduce(function (a, b) { return a < b ? a : b; });
var max = dates.reduce(function (a, b) { return a > b ? a : b; });

It depends on how precise you want the comparison to be. If you want to compare for exactly the same number, then just go with ==. (You almost never want to do this unless you actually want exactly the same number.) On any decent platform you can also do the following:
diff= a - b; return fabs(diff)<EPSILON;
as fabs
tends to be pretty fast. By pretty fast I mean it is basically a bitwise AND, so it better be fast.
And integer tricks for comparing doubles and floats are nice but tend to make it more difficult for the various CPU pipelines to handle effectively. And it's definitely not faster on certain in-order architectures these days due to using the stack as a temporary storage area for values that are being used frequently. (Load-hit-store for those who care.)
Try the following to see if you have the proper repository installed:
# yum search java | grep 'java-'
This is going to return a list of available packages that have java in the title. Specifically we are interested in the java- anything, as the jdk will typically be in 'java-version#' type format... Anyhow, if you have to install a repo look at Dag Wieers repo:
http://dag.wieers.com/rpm/FAQ.php#B
After you've got it installed try yum search again... This time you'll have a bunch of java stuff.
# yum search java | grep 'java-'
This will return the list of the available java packages. You can install one like this:
# yum install java-1.7.0-openjdk.x86_64
The default parser can parse your input. So you don't need a custom formatter and
String dateTime = "2012-02-22T02:06:58.147Z";
ZonedDateTime d = ZonedDateTime.parse(dateTime);
works as expected.
That only works for numbers less than 1.
select to_char(12.34, '0D99') from dual;
-- Result: #####
This won't work.
You could do something like this but this results in leading whitespaces:
select to_char(12.34, '999990D99') from dual;
-- Result: ' 12,34'
Ultimately, you could add a TRIM to get rid of the whitespaces again but I wouldn't consider that a proper solution either...
select trim(to_char(12.34, '999990D99')) from dual;
-- Result: 12,34
Again, this will only work for numbers with 6 digits max.
Edit: I wanted to add this as a comment on DCookie's suggestion but I can't.
Drop root privileges after you bind to port 80 (or 443).
This allows port 80/443 to remain protected, while still preventing you from serving requests as root:
function drop_root() {
process.setgid('nobody');
process.setuid('nobody');
}
A full working example using the above function:
var process = require('process');
var http = require('http');
var server = http.createServer(function(req, res) {
res.write("Success!");
res.end();
});
server.listen(80, null, null, function() {
console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
drop_root();
console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
});

As a complement to other answers note that you can also put the lang
attribute on various HTML tags inside a page.
For example to give a hint to the spellchecker that the input text should be in english:
<input ... spellcheck="true" lang="en"> ...

@DSM's answer is perfectly fine in almost any normal scenario. But if you're the type of programmer who wants to go a little deeper than the surface level, you might be interested to know that it is a little faster to call numpy functions on the underlying .to_numpy()
(or .values
for <0.24) array instead of directly calling the (cythonized) functions defined on the DataFrame/Series objects.
For example, you can use ndarray.max()
along the first axis.
# Data borrowed from @DSM's post.
df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
df
A B
0 1 -2
1 2 8
2 3 1
df['C'] = df[['A', 'B']].values.max(1)
# Or, assuming "A" and "B" are the only columns,
# df['C'] = df.values.max(1)
df
A B C
0 1 -2 1
1 2 8 8
2 3 1 3
If your data has NaN
s, you will need numpy.nanmax
:
df['C'] = np.nanmax(df.values, axis=1)
df
A B C
0 1 -2 1
1 2 8 8
2 3 1 3
You can also use numpy.maximum.reduce
. numpy.maximum
is a ufunc (Universal Function), and every ufunc has a reduce
:
df['C'] = np.maximum.reduce(df['A', 'B']].values, axis=1)
# df['C'] = np.maximum.reduce(df[['A', 'B']], axis=1)
# df['C'] = np.maximum.reduce(df, axis=1)
df
A B C
0 1 -2 1
1 2 8 8
2 3 1 3
np.maximum.reduce
and np.max
appear to be more or less the same (for most normal sized DataFrames)—and happen to be a shade faster than DataFrame.max
. I imagine this difference roughly remains constant, and is due to internal overhead (indexing alignment, handling NaNs, etc).
The graph was generated using perfplot. Benchmarking code, for reference:

Interlocked functions do not lock. They are atomic, meaning that they can complete without the possibility of a context switch during increment. So there is no chance of deadlock or wait.
I would say that you should always prefer it to a lock and increment.
Volatile is useful if you need writes in one thread to be read in another, and if you want the optimizer to not reorder operations on a variable (because things are happening in another thread that the optimizer doesn't know about). It's an orthogonal choice to how you increment.
This is a really good article if you want to read more about lock-free code, and the right way to approach writing it
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
When you start StreamWriter it's override the text was there before. You can use append property like so:
TextWriter t = new StreamWriter(path, true);
You can use npm shrinkwrap functionality, in order to override any dependency or sub-dependency.
I've just done this in a grunt
project of ours. We needed a newer version of connect, since 2.7.3
. was causing trouble for us. So I created a file named npm-shrinkwrap.json
:
{
"dependencies": {
"grunt-contrib-connect": {
"version": "0.3.0",
"from": "[email protected]",
"dependencies": {
"connect": {
"version": "2.8.1",
"from": "connect@~2.7.3"
}
}
}
}
}
npm
should automatically pick it up while doing the install for the project.
(See: https://nodejs.org/en/blog/npm/managing-node-js-dependencies-with-shrinkwrap/)
Try these:
Table definition:
DROP TABLE IF EXISTS category;
CREATE TABLE category (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(20),
parent_id INT,
CONSTRAINT fk_category_parent FOREIGN KEY (parent_id)
REFERENCES category (id)
) engine=innodb;
Experimental rows:
INSERT INTO category VALUES
(19, 'category1', NULL),
(20, 'category2', 19),
(21, 'category3', 20),
(22, 'category4', 21),
(23, 'categoryA', 19),
(24, 'categoryB', 23),
(25, 'categoryC', 23),
(26, 'categoryD', 24);
Recursive Stored procedure:
DROP PROCEDURE IF EXISTS getpath;
DELIMITER $$
CREATE PROCEDURE getpath(IN cat_id INT, OUT path TEXT)
BEGIN
DECLARE catname VARCHAR(20);
DECLARE temppath TEXT;
DECLARE tempparent INT;
SET max_sp_recursion_depth = 255;
SELECT name, parent_id FROM category WHERE id=cat_id INTO catname, tempparent;
IF tempparent IS NULL
THEN
SET path = catname;
ELSE
CALL getpath(tempparent, temppath);
SET path = CONCAT(temppath, '/', catname);
END IF;
END$$
DELIMITER ;
Wrapper function for the stored procedure:
DROP FUNCTION IF EXISTS getpath;
DELIMITER $$
CREATE FUNCTION getpath(cat_id INT) RETURNS TEXT DETERMINISTIC
BEGIN
DECLARE res TEXT;
CALL getpath(cat_id, res);
RETURN res;
END$$
DELIMITER ;
Select example:
SELECT id, name, getpath(id) AS path FROM category;
Output:
+----+-----------+-----------------------------------------+
| id | name | path |
+----+-----------+-----------------------------------------+
| 19 | category1 | category1 |
| 20 | category2 | category1/category2 |
| 21 | category3 | category1/category2/category3 |
| 22 | category4 | category1/category2/category3/category4 |
| 23 | categoryA | category1/categoryA |
| 24 | categoryB | category1/categoryA/categoryB |
| 25 | categoryC | category1/categoryA/categoryC |
| 26 | categoryD | category1/categoryA/categoryB/categoryD |
+----+-----------+-----------------------------------------+
Filtering rows with certain path:
SELECT id, name, getpath(id) AS path FROM category HAVING path LIKE 'category1/category2%';
Output:
+----+-----------+-----------------------------------------+
| id | name | path |
+----+-----------+-----------------------------------------+
| 20 | category2 | category1/category2 |
| 21 | category3 | category1/category2/category3 |
| 22 | category4 | category1/category2/category3/category4 |
+----+-----------+-----------------------------------------+
sed is a much better tool for the job: sed -n '/re/,$p' file
where re is regexp.
Another option is grep's --after-context flag. You need to pass in a number to end at, using wc on the file should give the right value to stop at. Combine this with -n and your match expression.
Here's an HTML5 alternative to homebrew: http://www.rgraph.net/ You might be able to reverse engineer their methods....
You might also consider something like Flot (http://code.google.com/p/flot/) or GCharts: (http://www.maxb.net/scripts/jgcharts/include/demo/#1) It's not quite as cool, but fully backwards compatible and scary easy to implement.
For documentation purpose, it's better to list the string values that are legal:

PropTypes.number,
PropTypes.oneOf([ 'SMALL', 'LARGE' ]),
]),
A static library(.a) is a library that can be linked directly into the final executable produced by the linker,it is contained in it and there is no need to have the library into the system where the executable will be deployed.
A shared library(.so) is a library that is linked but not embedded in the final executable, so will be loaded when the executable is launched and need to be present in the system where the executable is deployed.
A dynamic link library on windows(.dll) is like a shared library(.so) on linux but there are some differences between the two implementations that are related to the OS (Windows vs Linux) :
A DLL can define two kinds of functions: exported and internal. The exported functions are intended to be called by other modules, as well as from within the DLL where they are defined. Internal functions are typically intended to be called only from within the DLL where they are defined.
An SO library on Linux doesn't need special export statement to indicate exportable symbols, since all symbols are available to an interrogating process.
On Unix systems, for several projects, I added these lines into the CMakeLists.txt and it was compiling successfully because base (/usr/include) and local includes (/usr/local/include) go into separated directories:
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -I/usr/local/include -L/usr/local/lib")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/usr/local/include")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -L/usr/local/lib")
It appends the correct directory, including paths for the C and C++ compiler flags and the correct directory path for the linker flags.
Note: C++ compiler (c++) doesn't support -L, so we have to use CMAKE_EXE_LINKER_FLAGS
This worked for me:
git reset HEAD <filename>
There's a flag for that:
In [11]: df = pd.DataFrame([["foo1"], ["foo2"], ["bar"], [np.nan]], columns=['a'])
In [12]: df.a.str.contains("foo")
Out[12]:
0 True
1 True
2 False
3 NaN
Name: a, dtype: object
In [13]: df.a.str.contains("foo", na=False)
Out[13]:
0 True
1 True
2 False
3 False
Name: a, dtype: bool
See the str.replace
docs:
na : default NaN, fill value for missing values.
So you can do the following:
In [21]: df.loc[df.a.str.contains("foo", na=False)]
Out[21]:
a
0 foo1
1 foo2
Someone posted this link to the MDN in a comment, and I think it was very helpful. It describes things like ErrorTypes very thoroughly.
EvalError --- Creates an instance representing an error that occurs regarding the global function eval().
InternalError --- Creates an instance representing an error that occurs when an internal error in the JavaScript engine is thrown. E.g. "too much recursion".
RangeError --- Creates an instance representing an error that occurs when a numeric variable or parameter is outside of its valid range.
ReferenceError --- Creates an instance representing an error that occurs when de-referencing an invalid reference.
SyntaxError --- Creates an instance representing a syntax error that occurs while parsing code in eval().
TypeError --- Creates an instance representing an error that occurs when a variable or parameter is not of a valid type.
URIError --- Creates an instance representing an error that occurs when encodeURI() or decodeURI() are passed invalid parameters.
I had the same problem in my newly started project with minimum api 23, and finally i have added these lines of codes in my gradle dependency file and it solved the error:)

Thanks to all for the posts but unfortunatley none of the above solved my problem. Eventually what got it all working for me was to download eclipse indigo 3.7.2 and (this is very important) EXTRACT IT DIRECTLY INTO MY PROGRAMS FOLDER. Before I would extract it to my desktop and copy into the programs folder (C:\Program Files) but I would jus get an error message saying "The Eclipse executable launcher was unable to locate its companion shared library" when trying to run eclipse.
After extracting eclipse directly to my programs folder I ran it and added the ADT plugin the way reccomended in on the android site and so far all is working well :)
I'm on a windows 7 x64 machine and had jre-7u2-windows-x64.exe, jdk-7u2-windows-x64.exe and installer_r16-windows.exe installed before extracting eclipse.
I hope this can help someone else too :)
In an undirected graph (excluding multigraphs), the answer is n*(n-1)/2. In a directed graph an edge may occur in both directions between two nodes, then the answer is n*(n-1).
Arrays (called list
in python) use the []
notation. {}
is for dict
(also called hash tables, associated arrays, etc in other languages) so you won't have 'append' for a dict.
If you actually want an array (list), use:
array = []
array.append(valueToBeInserted)

To summarize and explain visually how it works. Code construction is as follows:
par(mar = c(3,2,2,1))
barplot(...all parameters...)
title("Title text", adj = 0.5, line = 0)
explanation:
par(mar = c(low, left, top, right)) - margins of the graph area.
title("text" - title text
adj = from left (0) to right (1) with anything in between: 0.1, 0.2, etc...
line = positive values move title text up, negative - down)

if LEN(ISNULL(@Value,''))=0
This check the field is empty
or NULL
If I'm not mistaken, the question requires "contains number", not "is number". So:
function hasNumber(myString) {
return /\d/.test(myString);
}
Just using git reflog
did not return the sha
for me.
Only the commit id
(which is 8 chars long and a sha is way longer)
So I used
git reflog --no-abbrev
And then do the same as mentioned above:
git checkout -b <branch> <sha>
