I think this does a good job of explaining.
The following is a UNION query that uses an ORDER BY clause:
select supplier_id, supplier_name
from suppliers
where supplier_id > 2000
UNION
select company_id, company_name
from companies
where company_id > 1000
ORDER BY 2;
Since the column names are different between the two "select" statements, it is more advantageous to reference the columns in the ORDER BY clause by their position in the result set.
In this example, we've sorted the results by supplier_name
/ company_name
in ascending order, as denoted by the "ORDER BY 2".
The supplier_name
/ company_name
fields are in position #2 in the
result set.

Since there is some routine from the the pthread family on the bottom (but I don't know that particular one), my guess would be that you have launched some thread as joinable that has terminated execution.
The exit state information of that thread is kept available until you call pthread_join
. Thus, the memory is kept in a loss record at program termination, but it is still reachable since you could use pthread_join
to access it.
If this analysis is correct, either launch these threads detached, or join them before terminating your program.
Edit: I ran your sample program (after some obvious corrections) and I don't have errors but the following
==18933== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 4 from 4)
--18933--
--18933-- used_suppression: 2 dl-hack3-cond-1
--18933-- used_suppression: 2 glibc-2.5.x-on-SUSE-10.2-(PPC)-2a
Since the dl-
thing resembles much of what you see I guess that you see a known problem that has a solution in terms of a suppression file for valgrind
. Perhaps your system is not up to date, or your distribution doesn't maintain these things. (Mine is ubuntu 10.4, 64bit)
Here is my solution for this :
mkdir temp
mkdir results
cp /usr/share/dict/american-english ~/temp/american-english-dictionary

cat ~/temp/american-english-dictionary | wc -l > ~/results/count-american-english-dictionary
cat ~/temp/british-english-dictionary | wc -l > ~/results/count-british-english-dictionary
grep -Fxf ~/temp/american-english-dictionary ~/temp/british-english-dictionary > ~/results/common-english

grep -Fxvf ~/results/common-english ~/temp/british-english-dictionary > ~/results/unique-british-english
An answer to a slightly different question: You can use vh
units to pad elements to the center of the viewport:
.centerme {
margin-top: 50vh;
background: red;
}
<div class="centerme">middle</div>
Check out the set(int index, E element)
method in the List interface
They both track your changes to the collection, just call the SaveChanges() method that should update the DB.
Here you can find some public REST services for encryption and security related things: http://security.jelastic.servint.net
public List<State> GetcountryCodeStates(List<string> countryCodes)
{
List<State> states = new List<State>();
states = (from a in _objdatasources.StateList.AsEnumerable()
where countryCodes.Any(c => c.Contains(a.CountryCode))
select a).ToList();
return states;
}
Matching any text but those matching a pattern is usually achieved with splitting the string with the regex pattern.
Examples:
Regex.Split(text, @"red|green|blue")
or, to get rid of empty values, Regex.Split(text, @"red|green|blue").Where(x => !string.IsNullOrEmpty(x))
(see demo)Regex.Split(text, "red|green|blue")
or, to remove empty items, Regex.Split(text, "red|green|blue").Where(Function(s) Not String.IsNullOrWhitespace(s))
(see demo, or this demo where LINQ is supported)text.split(/red|green|blue/)
(no need to use g
modifier here!) (to get rid of empty values, use text.split(/red|green|blue/).filter(Boolean)
), see demotext.split("red|green|blue")
, or - to keep all trailing empty items - use text.split("red|green|blue", -1)
, or to remove all empty items use more code to remove them (see demo)text.split(/red|green|blue/)
, to get all trailing items use text.split(/red|green|blue/, -1)
and to remove all empty items use text.split(/red|green|blue/).findAll {it != ""})
(see demo)text.split(Regex("red|green|blue"))
or, to remove blank items, use text.split(Regex("red|green|blue")).filter{ !it.isBlank() }
, see demotext.split("red|green|blue")
, or to keep all trailing empty items, use text.split("red|green|blue", -1)
and to remove all empty items, use text.split("red|green|blue").filter(_.nonEmpty)
(see demo)text.split(/red|green|blue/)
, to get rid of empty values use .split(/red|green|blue/).reject(&:empty?)
(and to get both leading and trailing empty items, use -1
as the second argument, .split(/red|green|blue/, -1)
) (see demo)my @result1 = split /red|green|blue/, $text;
, or with all trailing empty items, my @result2 = split /red|green|blue/, $text, -1;
, or without any empty items, my @result3 = grep { /\S/ } split /red|green|blue/, $text;
(see demo)preg_split('~red|green|blue~', $text)
or preg_split('~red|green|blue~', $text, -1, PREG_SPLIT_NO_EMPTY)
to output no empty items (see demo)re.split(r'red|green|blue', text)
or, to remove empty items, list(filter(None, re.split(r'red|green|blue', text)))
(see demo)regexp.MustCompile("red|green|blue").Split(text, -1)
, and if you need to remove empty items, use this code. See Go demo.NOTE: If you patterns contain capturing groups, regex split functions/methods may behave differently, also depending on additional options. Please refer to the appropriate split method documentation then.
This is how I solve my problem:
parseFloat(parseFloat(floatString).toFixed(2));
Beyond historical (good and already reported) reasons, there's is also a little problem with operators precedence: dot operator has higher priority than star operator, so if you have struct containing pointer to struct containing pointer to struct... These two are equivalent:
(*(*(*a).b).c).d
a->b->c->d
But the second is clearly more readable. Arrow operator has the highest priority (just as dot) and associates left to right. I think this is clearer than use dot operator both for pointers to struct and struct, because we know the type from the expression without have to look at the declaration, that could even be in another file.
I made a simple pure-go solution, which is under development.
redis-cli: https://github.com/holys/redis-cli
Build once, and run everywhere. Fully portable.
Please feel free to have a try.
There's an error in the pattern of your SimpleDateFormat. it should be
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm");
It depends. In a debug build, I want to see the original stack trace with as little effort as possible. In that case, "throw;" fits the bill. In a release build, however, (a) I want to log the error with the original stack trace included, and once that's done, (b) refashion the error handling to make more sense to the user. Here "Throw Exception" makes sense. It's true that rethrowing the error discards the original stack trace, but a non-developer gets nothing out of seeing stack trace information so it's okay to rethrow the error.
void TrySuspectMethod()
{
try
{
SuspectMethod();
}
#if DEBUG
catch
{
//Don't log error, let developer see
//original stack trace easily
throw;
#else
catch (Exception ex)
{
//Log error for developers and then
//throw a error with a user-oriented message
throw new Exception(String.Format
("Dear user, sorry but: {0}", ex.Message));
#endif
}
}
The way the question is worded, pitting "Throw:" vs. "Throw ex;" makes it a bit of a red-herring. The real choice is between "Throw;" and "Throw Exception," where "Throw ex;" is an unlikely special case of "Throw Exception."
SQL Server
does not support CREATE TABLE AS SELECT
.
Use this:
SELECT *
INTO A
FROM myview
or
SELECT TOP 10
*
INTO A
FROM myview
ORDER BY
id
along with answer of this link
https://stackoverflow.com/a/19844531/6767365
rename these files. I renamed my project to MvcMovie and it works fine
You don't need the SELECT
DECLARE @LastChangeDate as date
SET @LastChangeDate = GetDate()
when you add a new data set to a geom you need to use the data=
argument. Or put the arguments in the proper order mapping=..., data=...
. Take a look at the arguments for ?geom_line
.
Thus:
p + geom_line(data=df.last, aes(HrEnd, MWh, group=factor(Date)), color="red")
Or:
p + geom_line(aes(HrEnd, MWh, group=factor(Date)), df.last, color="red")
I think @Richard Garside is correct.
I suggest some changes to clear even more the code.
Change this
onChange={(e) => this.update("field2", e)}
To this
onChange={this.handleOnChange}
And also, change this
this.setState({ [name]: e.target.value });
To this
this.setState({ [e.target.name]: e.target.value})
Besides, you have to add the "name" attribute to the field with a value that relates with the key on the state object.
The Abandon
method should work (MSDN):
Session.Abandon();
If you want to remove a specific item from the session use (MSDN):
Session.Remove("YourItem");
EDIT: If you just want to clear a value you can do:
Session["YourItem"] = null;
If you want to clear all keys do:
Session.Clear();
If none of these are working for you then something fishy is going on. I would check to see where you are assigning the value and verify that it is not getting reassigned after you clear the value.
Simple check do:
Session["YourKey"] = "Test"; // creates the key
Session.Remove("YourKey"); // removes the key
bool gone = (Session["YourKey"] == null); // tests that the remove worked

Have you tried to increase output_buffering in your php.ini?
If you use the credential file at ~/.aws/credentials and use the default profile as below:
[default]
aws_access_key_id=<your access key>
aws_secret_access_key=<your secret access key>
You do not need to use BasicAWSCredential
or AWSCredentialsProvider
. The SDK can pick up the credentials from the default profile, just by initializing the client object with the default constructor. Example below:
AmazonEC2Client ec2Client = new AmazonEC2Client();
In addition sometime you would need to initialize the client with the ClientConfiguration to provide proxy settings etc. Example below.
ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost("proxyhost");
clientConfiguration.setProxyPort(proxyport);
AmazonEC2Client ec2Client = new AmazonEC2Client(clientConfiguration);
Only use:
sudo apt-get install php5-sqlite
and later
sudo service apache2 restart
This simple extension in Swift works well.
extension String {
func size(OfFont font: UIFont) -> CGSize {
return (self as NSString).size(attributes: [NSFontAttributeName: font])
}
}
Usage:
let string = "hello world!"
let font = UIFont.systemFont(ofSize: 12)
let width = string.size(OfFont: font).width // size: {w: 98.912 h: 14.32}
You can simply use the return;
example
$(document).ready(function () {
alert(1);
return;
alert(2);
alert(3);
alert(4);
});
The return will return to the main caller function test1(); and continue from there to test3();

This is tested with firefox and chrome. I don't know how this is handled by IE or Safari
Well if you are doing this in Asp.Net or have access to HttpContext.Current.Request I'd say these are easier and more general ways of getting them:
var scheme = Request.Url.Scheme; // will get http, https, etc.
var host = Request.Url.Host; // will get www.mywebsite.com
var port = Request.Url.Port; // will get the port
var path = Request.Url.AbsolutePath; // should get the /pages/page1.aspx part, can't remember if it only get pages/page1.aspx
I hope this helps. :)
Using the java.time package in Java 8:
Instant start = Instant.now();
Thread.sleep(63553);
Instant end = Instant.now();
System.out.println(Duration.between(start, end));
Output is in ISO 8601 Duration format: PT1M3.553S
(1 minute and 3.553 seconds).
The equivalent of .live() in 1.7 looks like this:
$(document).on('click', '#child', function() ...);
Basically, watch the document for click events and filter them for #child.
In Javascript you can do that by using the typeof function
function foo(bar){
alert(typeof(bar));
}
I just dealt with this problem, so I'll add my solution as a supplement on other answers given.
The problem here is that useEffect
doesn't really work as you would want it to, since the call only gets triggered after the first render so there is an unwanted delay.
If you use some state manager like redux, chances are that you will get a flicker on the screen because of lingering state in the store.
What you really want is to use useLayoutEffect
since this gets triggered immediately.
So I wrote a small utility function that I put in the same directory as my router:
export const callApis = (fn, path) => {
useLayoutEffect(() => {
fn();
}, [path]);
};
Which I call from within the component HOC like this:
callApis(() => getTopicById({topicId}), path);
path
is the prop that gets passed in the match
object when using withRouter
.
I'm not really in favour of listening / unlistening manually on history. That's just imo.
class AppProvider extends Component {
constructor() {
super();
window.alertMessage = this.alertMessage.bind(this);
}
alertMessage() {
console.log('Hello World');
}
}
You can call this method from the window by using window.alertMessage()
.
You can use a Split
:
$text = "test.txt ; 131 136 80 89 119 17 60 123 210 121 188 42 136 200 131 198"
$separator = ";" # you can put many separator like this "; : ,"
$parts = $text.split($separator)
echo $parts[0] # return test.txt
echo $parts[1] # return the part after the separator
The instance that your base class reference is referring to is not an instance of your child class. There's nothing wrong.
More specifically:
Base derivedInstance = new Derived();
Base baseInstance = new Base();
Derived good = (Derived)derivedInstance; // OK
Derived fail = (Derived)baseInstance; // Throws InvalidCastException
For the cast to be successful, the instance that you're downcasting must be an instance of the class that you're downcasting to (or at least, the class you're downcasting to must be within the instance's class hierarchy), otherwise the cast will fail.
What is the difference?
From the documentation:
- - (Boolean)
instance_of?(class)
- Returns
true
ifobj
is an instance of the given class.
and:
- - (Boolean)
is_a?(class)
- (Boolean)kind_of?(class)
- Returns
true
ifclass
is the class ofobj
, or ifclass
is one of the superclasses ofobj
or modules included inobj
.
If that is unclear, it would be nice to know what exactly is unclear, so that the documentation can be improved.
When should I use which?
Never. Use polymorphism instead.
Why are there so many of them?
I wouldn't call two "many". There are two of them, because they do two different things.
As stated,
innodb_buffer_pool_size=50M
Following the convention on the other predefined variables, make sure there is no space either side of the equals sign.
Then run
sudo service mysqld stop
sudo service mysqld start
Note
Sometimes, e.g. on Ubuntu, the MySQL daemon is named mysql
as opposed to mysqld
I find that running /etc/init.d/mysqld restart
doesn't always work and you may get an error like
Stopping mysqld: [FAILED]
Starting mysqld: [ OK ]
To see if the variable has been set, run show variables
and see if the value has been updated.
For newer version of Git.
I tried git add -A
and this prompted,
warning: The behavior of 'git add --all (or -A)' with no path argument from a subdirectory of the tree will change in Git 2.0 and should not be used anymore. To add content for the whole tree, run:
git add --all :/ (or git add -A :/)
To restrict the command to the current directory, run:
git add --all . (or git add -A .)
With the current Git version, the command is restricted to the current directory.
Then I tried below which worked.
git add --all :/

Jerryf's answer is fine, except for one flaw.
The onload event should be set before the src. Sometimes the src can be loaded instantly and never fire the onload event.
(Like Totty.js pointed out.)
var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");
var image = new Image();
image.onload = function() {
ctx.drawImage(image, 0, 0);
};
image.src = "data:image/ png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";
You are almost always better off using an options hash.
def ldap_get(base_dn, filter, options = {})
options[:scope] ||= LDAP::LDAP_SCOPE_SUBTREE

Hope this solved your problem.
There is a way more convenient 'percent'-formatting option for the .format()
format method:
>>> '{:.1%}'.format(1/3.0)
'33.3%'
You can use TreeSet
that automatically order list values:
import java.util.Iterator;
import java.util.TreeSet;
public class TreeSetExample {
public static void main(String[] args) {
System.out.println("Tree Set Example!\n");
TreeSet <String>tree = new TreeSet<String>();
tree.add("aaa");
tree.add("acbbb");
tree.add("aab");
tree.add("c");
tree.add("a");
Iterator iterator;
iterator = tree.iterator();
System.out.print("Tree set data: ");
//Displaying the Tree set data
while (iterator.hasNext()){
System.out.print(iterator.next() + " ");
}
}
}
I lastly add 'a' but last element must be 'c'.
In general you can use pandas rename function here. Given your dataframe you could change to a new name like this. If you had more columns you could also rename those in the dictionary. The 0 is the current name of your column
import pandas as pd
import numpy as np
e = np.random.normal(size=100)
e_dataframe = pd.DataFrame(e)
e_dataframe.rename(index=str, columns={0:'new_column_name'})
Here is a one-line-command example with both computing the proper checksum of the file, like you just downloaded, and comparing it with the published checksum of the original.
For instance, I wrote an example for downloadings from the Apache JMeter project. In this case you have:
3a84491f10fb7b147101cf3926c4a855 *apache-jmeter-4.0.zip
Then using this PowerShell command, you can verify the integrity of the downloaded file:
PS C:\Distr> (Get-FileHash .\apache-jmeter-4.0.zip -Algorithm MD5).Hash -eq (Get-Content .\apache-jmeter-4.0.zip.md5 | Convert-String -Example "hash path=hash")
Output:
True
Explanation:
The first operand of -eq
operator is a result of computing the checksum for the file:
(Get-FileHash .\apache-jmeter-4.0.zip -Algorithm MD5).Hash
The second operand is the published checksum value. We firstly get content of the file.md5 which is one string and then we extract the hash value based on the string format:
Get-Content .\apache-jmeter-4.0.zip.md5 | Convert-String -Example "hash path=hash"
Both file and file.md5 must be in the same folder for this command work.
You can use a lookahead:
/(?=\S)[^\\]/
The below url is doing same as above answers. Instead of downloading some jar files and doing much activities, you can try to decompile by:
Both will work but xhtml standard requires you to specify the type
too:
<script type="text/javascript">..</script>
<!ELEMENT SCRIPT - - %Script; -- script statements -->
<!ATTLIST SCRIPT
charset %Charset; #IMPLIED -- char encoding of linked resource --
type %ContentType; #REQUIRED -- content type of script language --
src %URI; #IMPLIED -- URI for an external script --
defer (defer) #IMPLIED -- UA may defer execution of script --
>
type = content-type [CI] This attribute specifies the scripting language of the element's contents and overrides the default scripting language. The scripting language is specified as a content type (e.g., "text/javascript"). Authors must supply a value for this attribute. There is no default value for this attribute.
Notices the emphasis above.
http://www.w3.org/TR/html4/interact/scripts.html
Note: As of HTML5 (far away), the type
attribute is not required and is default.
My modern variant:
function blob2file(blobData) {
const fd = new FormData();
fd.set('a', blobData);
return fd.get('a');
}
While many of the answers produce useful results, I think the hustle of maintaining a complex script for this task is not worth it. This is mainly because most distros use different cron daemons.

In the <system.web>
element, add the following element:
<httpCookies requireSSL="true" />
However, if you have a <forms>
element in your system.web\authentication
block, then this will override the setting in httpCookies
, setting it back to the default false
.
In that case, you need to add the requireSSL="true"
attribute to the forms element as well.
So you will end up with:
<system.web>
<authentication mode="Forms">
<forms requireSSL="true">
<!-- forms content -->
</forms>
</authentication>
</system.web>
Yep, Oracle has temporary tables. Here is a link to an AskTom article describing them and here is the official oracle CREATE TABLE documentation.
However, in Oracle, only the data in a temporary table is temporary. The table is a regular object visible to other sessions. It is a bad practice to frequently create and drop temporary tables in Oracle.
CREATE GLOBAL TEMPORARY TABLE today_sales(order_id NUMBER)
ON COMMIT PRESERVE ROWS;
Oracle 18c added private temporary tables, which are single-session in-memory objects. See the documentation for more details. Private temporary tables can be dynamically created and dropped.
CREATE PRIVATE TEMPORARY TABLE ora$ptt_today_sales AS
SELECT * FROM orders WHERE order_date = SYSDATE;
Temporary tables can be useful but they are commonly abused in Oracle. They can often be avoided by combining multiple steps into a single SQL statement using inline views.
after you have pulled and updated your workspace do a thg and right click on the change set you want to get rid of and then click modify history -> strip, it will remove the change set and you will point to default tip.
Follow this, it can be like what you are looking:
var obj = {_x000D_
Objone: 'one',_x000D_
Objtwo: 'two'_x000D_
};_x000D_
_x000D_
var key = "Objone";_x000D_
delete obj[key];_x000D_
console.log(obj); // prints { "objtwo": two}
_x000D_
For persistently setting environment variables, you can use one of the existing roles over at Ansible Galaxy. I recommend weareinteractive.environment.
Using ansible-galaxy:
$ ansible-galaxy install weareinteractive.environment
Using requirements.yml:
- src: franklinkim.environment
Then in your playbook:
- hosts: all
sudo: yes
roles:
- role: franklinkim.environment
environment_config:
NODE_ENV: staging
DATABASE_NAME: staging
I wrote a wrapper, that will cache text surfaces, only re-render when dirty. googlecode/ninmonkey/nin.text/demo/

A better approach is to store the old value using .data. This spares the creation of a global var which you should stay away from and keeps the information encapsulated within the element. A real world example as to why Global Vars are bad is documented here
e.g
<script>
//look no global needed:)
$(document).ready(function(){
// Get the initial value
var $el = $('#myInputElement');
$el.data('oldVal', $el.val() );
$el.change(function(){
//store new value
var $this = $(this);
var newValue = $this.data('newVal', $this.val());
})
.focus(function(){
// Get the value when input gains focus
var oldValue = $(this).data('oldVal');
});
});
</script>
<input id="myInputElement" type="text">
Are the files on the same server as the PHP script? If so, just keep the files out of the web root and make sure your PHP script has read permissions for wherever they're stored.
Not sure how efficient this might be in terms of performance, but this is what I use using array destructuring to keep everything nice and short:
const shareElements = (arr1, arr2) => {
const typeArr = [...arr1, ...arr2]
const typeSet = new Set(typeArr)
return typeArr.length > typeSet.size
}
Since sets cannot have duplicate elements while arrays can, combining both input arrays, converting it to a set, and comparing the set size and array length would tell you if they share any elements.
No, not directly in the std::list
template itself. You can however use std::find
algorithm like that:
std::list<int> my_list;
//...
int some_value = 12;
std::list<int>::iterator iter = std::find (my_list.begin(), my_list.end(), some_value);
// now variable iter either represents valid iterator pointing to the found element,
// or it will be equal to my_list.end()
The simplest answer is to ensure that your pod or replication controller yaml/json files add the pod IP as an environment variable by adding the config block defined below. (the block below additionally makes the name and namespace available to the pod)
env:
- name: MY_POD_NAME
valueFrom:
fieldRef:
fieldPath: metadata.name
- name: MY_POD_NAMESPACE
valueFrom:
fieldRef:
fieldPath: metadata.namespace
- name: MY_POD_IP
valueFrom:
fieldRef:
fieldPath: status.podIP
Recreate the pod/rc and then try
echo $MY_POD_IP
also run env
to see what else kubernetes provides you with.

Table is the obvious choice, but it returns an object of class table
which takes a few annoying steps to transform back into a data.frame
So, if you're OK using dplyr, you use the command tally
:
library(dplyr)
df = data.frame(sex=sample(c("M", "F"), 100000, replace=T), occupation=sample(c('Analyst', 'Student'), 100000, replace=T)
df %>% group_by_all() %>% tally()
# A tibble: 4 x 3
# Groups: sex [2]
sex occupation `n()`
<fct> <fct> <int>
1 F Analyst 25105
2 F Student 24933
3 M Analyst 24769
4 M Student 25193
I recommend IdentityServer.This is a .NET Foundation project and covers many issues about authentication and authorization.
IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.
check out the documentation and the demo.
In addition to the other answers, on a recent C library (Posix 2008 compliant), you could use getline. See this answer (to a related question).
Convert a value to JSON, optionally replacing values if a replacer function is specified, or optionally including only the specified properties if a replacer array is specified.
From Java SE 6 HotSpot[tm] Virtual Machine Garbage Collection Tuning
the following
Excessive GC Time and OutOfMemoryError
The concurrent collector will throw an OutOfMemoryError if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection and less than 2% of the heap is recovered, an OutOfMemoryError will be thrown. This feature is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. If necessary, this feature can be disabled by adding the option -XX:-UseGCOverheadLimit to the command line.
The policy is the same as that in the parallel collector, except that time spent performing concurrent collections is not counted toward the 98% time limit. In other words, only collections performed while the application is stopped count toward excessive GC time. Such collections are typically due to a concurrent mode failure or an explicit collection request (e.g., a call to System.gc()).
in conjunction with a passage further down
One of the most commonly encountered uses of explicit garbage collection occurs with RMIs distributed garbage collection (DGC). Applications using RMI refer to objects in other virtual machines. Garbage cannot be collected in these distributed applications without occasionally collection the local heap, so RMI forces full collections periodically. The frequency of these collections can be controlled with properties. For example,
java -Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000
specifies explicit collection once per hour instead of the default rate of once per minute. However, this may also cause some objects to take much longer to be reclaimed. These properties can be set as high as Long.MAX_VALUE to make the time between explicit collections effectively infinite, if there is no desire for an upper bound on the timeliness of DGC activity.
Seems to imply that the evaluation period for determining the 98% is one minute long, but it might be configurable on Sun's JVM with the correct define.
Of course, other interpretations are possible.
I've built upon the answer above - https://stackoverflow.com/a/11155031/2060486 - to create a shadow around ALL sides..
private static final int GRAY_COLOR_FOR_SHADE = Color.argb(50, 79, 79, 79);
// this method takes a bitmap and draws around it 4 rectangles with gradient to create a
// shadow effect.
public static Bitmap addShadowToBitmap(Bitmap origBitmap) {
int shadowThickness = 13; // can be adjusted as needed
int bmpOriginalWidth = origBitmap.getWidth();
int bmpOriginalHeight = origBitmap.getHeight();
int bigW = bmpOriginalWidth + shadowThickness * 2; // getting dimensions for a bigger bitmap with margins
int bigH = bmpOriginalHeight + shadowThickness * 2;
Bitmap containerBitmap = Bitmap.createBitmap(bigW, bigH, Bitmap.Config.ARGB_8888);
Bitmap copyOfOrigBitmap = Bitmap.createScaledBitmap(origBitmap, bmpOriginalWidth, bmpOriginalHeight, false);
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
Canvas canvas = new Canvas(containerBitmap); // drawing the shades on the bigger bitmap
//right shade - direction of gradient is positive x (width)
Shader rightShader = new LinearGradient(bmpOriginalWidth, 0, bigW, 0, GRAY_COLOR_FOR_SHADE,
Color.TRANSPARENT, Shader.TileMode.CLAMP);
paint.setShader(rightShader);
canvas.drawRect(bigW - shadowThickness, shadowThickness, bigW, bigH - shadowThickness, paint);
//bottom shade - direction is positive y (height)
Shader bottomShader = new LinearGradient(0, bmpOriginalHeight, 0, bigH, GRAY_COLOR_FOR_SHADE,
Color.TRANSPARENT, Shader.TileMode.CLAMP);
paint.setShader(bottomShader);
canvas.drawRect(shadowThickness, bigH - shadowThickness, bigW - shadowThickness, bigH, paint);
//left shade - direction is negative x
Shader leftShader = new LinearGradient(shadowThickness, 0, 0, 0, GRAY_COLOR_FOR_SHADE,
Color.TRANSPARENT, Shader.TileMode.CLAMP);
paint.setShader(leftShader);
canvas.drawRect(0, shadowThickness, shadowThickness, bigH - shadowThickness, paint);
//top shade - direction is negative y
Shader topShader = new LinearGradient(0, shadowThickness, 0, 0, GRAY_COLOR_FOR_SHADE,
Color.TRANSPARENT, Shader.TileMode.CLAMP);
paint.setShader(topShader);
canvas.drawRect(shadowThickness, 0, bigW - shadowThickness, shadowThickness, paint);
// starting to draw bitmap not from 0,0 to get margins for shade rectangles
canvas.drawBitmap(copyOfOrigBitmap, shadowThickness, shadowThickness, null);
return containerBitmap;
}
Change the color in the const as you see fit.
This will squash second commit into the first one:
A-B-C-... -> AB-C-...
git filter-branch --commit-filter '
if [ "$GIT_COMMIT" = <sha1ofA> ];
then
skip_commit "$@";
else
git commit-tree "$@";
fi
' HEAD
Commit message for AB will be taken from B (although I'd prefer from A).
Has the same effect as Uwe Kleine-König's answer, but works for non-initial A as well.
If you can live with multiple output paths having the same level of depth and folder structure there is a way to do this in webpack 2 (have yet to test with webpack 1.x)
Basically you don't follow the doc rules and you provide a path for the filename.
module.exports = {
entry: {
foo: 'foo.js',
bar: 'bar.js'
},
output: {
path: path.join(__dirname, 'components'),
filename: '[name]/dist/[name].bundle.js', // Hacky way to force webpack to have multiple output folders vs multiple files per one path
}
};
That will take this folder structure
/-
foo.js
bar.js
And turn it into
/-
foo.js
bar.js
components/foo/dist/foo.js
components/bar/dist/bar.js
Piping some greps can do it (it runs in POSIX shell and under BusyBox):
cat my-file | grep -A1 my-regexp | grep -v -- '--' | grep -v my-regexp
-v
will show non-matching lines@Ric Jafe's solution is what worked for me.
This is exactly what I was looking for. A way to push it through for research test code. Nothing fancy. Yeah I know that that's what they all say :) The various maven plugin solutions seem to be overkill for my purposes. I have some jars that were given to me as 3rd party libs with a pom file. I want it to compile/run quickly. This solution which I trivially adapted to python worked wonders for me. Cut and pasted into my pom. Python/Perl code for this task is in this Q&A: Can I add jars to maven 2 build classpath without installing them?
def AddJars(jarList):
s1 = ''
for elem in jarList:
s1+= """

return s1
I ran into the same issue in Ubuntu 18.04.3 LTS. In my case, apt installed gradle version 4.4.1. The already-install java version was 11.0.4
The build message I got was
Could not determine java version from '11.0.4'.
At the time, most of the online docs referenced gradle version 5.6, so I did the following:
sudo add-apt-repository ppa:cwchien/gradle
sudo apt update
sudo apt upgrade gradle
Then I repeated the project initialiation (using "gradle init" with the defaults). After that, "./gradlew build" worked correctly.
I later read a comment regarding a change in format of the output from "java --version" that caused gradle to break, which was fixed in a later version of gradle.
I think the accepted answer is an awful way of handling this.
I don't know what the use case is, but please consider a protected method in the base class
@protected
void doSomething() {
}
and override it in the derived class.
When the event occurs, just call this method in the base class. The correct 'active' class will handle it then. The class itself can then check if it is not Paused()
.
Better yet, use an event bus like GreenRobot's, Square's, but that one is deprecated and suggests using RxJava
HashMap
implements Serializable
so you can use normal serialization to write hashmap to file
Here is the link for Java - Serialization example
In above code, you don't pass the kml data to your mapView anywhere in your code, as far as I can see. To display the route, you should parse the kml data i.e. via SAX parser, then display the route markers on the map.
See the code below for an example, but it's not complete though - just for you as a reference and get some idea.
This is a simple bean I use to hold the route information I will be parsing.
package com.myapp.android.model.navigation;
import java.util.ArrayList;
import java.util.Iterator;
public class NavigationDataSet {
private ArrayList<Placemark> placemarks = new ArrayList<Placemark>();
private Placemark currentPlacemark;
private Placemark routePlacemark;
public String toString() {
String s= "";
for (Iterator<Placemark> iter=placemarks.iterator();iter.hasNext();) {
Placemark p = (Placemark)iter.next();
s += p.getTitle() + "\n" + p.getDescription() + "\n\n";
}
return s;
}
public void addCurrentPlacemark() {
placemarks.add(currentPlacemark);
}
public ArrayList<Placemark> getPlacemarks() {
return placemarks;
}
public void setPlacemarks(ArrayList<Placemark> placemarks) {
this.placemarks = placemarks;
}
public Placemark getCurrentPlacemark() {
return currentPlacemark;
}
public void setCurrentPlacemark(Placemark currentPlacemark) {
this.currentPlacemark = currentPlacemark;
}
public Placemark getRoutePlacemark() {
return routePlacemark;
}
public void setRoutePlacemark(Placemark routePlacemark) {
this.routePlacemark = routePlacemark;
}
}
And the SAX Handler to parse the kml:
package com.myapp.android.model.navigation;
import android.util.Log;

Your myCoolDiv
element isn't a child of the player container. It's a child of the div
you created as a wrapper for it (markerDiv
in the first part of the code). Which is why it fails, removeChild
only removes children, not descendants.
You'd want to remove that wrapper div, or not add it at all.
Here's the "not adding it at all" option:
var markerDiv = document.createElement("div");_x000D_
markerDiv.innerHTML = "<div id='MyCoolDiv' style='color: #2b0808'>123</div>";_x000D_
document.getElementById("playerContainer").appendChild(markerDiv.firstChild);_x000D_
// -------------------------------------------------------------^^^^^^^^^^^_x000D_
_x000D_
setTimeout(function(){ _x000D_
var myCoolDiv = document.getElementById("MyCoolDiv");_x000D_
document.getElementById("playerContainer").removeChild(myCoolDiv);_x000D_
}, 1500);
_x000D_
<div id="playerContainer"></div>
_x000D_
Or without using the wrapper (although it's quite handy for parsing that HTML):
var myCoolDiv = document.createElement("div");_x000D_
// Don't reall need this: myCoolDiv.id = "MyCoolDiv";_x000D_
myCoolDiv.style.color = "#2b0808";_x000D_
myCoolDiv.appendChild(_x000D_
document.createTextNode("123")_x000D_
);_x000D_
document.getElementById("playerContainer").appendChild(myCoolDiv);_x000D_
_x000D_
setTimeout(function(){ _x000D_
// No need for this, we already have it from the above:_x000D_
// var myCoolDiv = document.getElementById("MyCoolDiv");_x000D_
document.getElementById("playerContainer").removeChild(myCoolDiv);_x000D_
}, 1500);
_x000D_

This is called string interpolation; it doesn't exist as such in Java.
One approach is to use String.format:
String string = String.format("A string %s", aVariable);
Another approach is to use a templating library such as Velocity or FreeMarker.
Use git rm foo
to stage the file for deletion. (This will also delete the file from the file system, if it hadn't been previously deleted. It can, of course, be restored from git, since it was previously checked in.)
To stage the file for deletion without deleting it from the file system, use git rm --cached foo
Exit

The utf8mb4

A nice read on How to support full Unicode in MySQL databases by Mathias Bynens can also shed some light on this.
To get the difference between two-moment format dates or javascript Date format indifference of minutes the most optimum solution is
const timeDiff = moment.duration((moment(apptDetails.end_date_time).diff(moment(apptDetails.date_time)))).asMinutes()
you can change the difference format as you need by just replacing the asMinutes() function
This answer has been very beautifully explained in book "Microservices Interview Questions, For Java Developers (Spring Boot, Spring Cloud, Cloud Native Applications) by Munish Chandel, Version 1.30, 25.03.2018.
The following content has been taken from this book, and total credit for this answer goes to the Author of the book i.e. Munish Chandel
application.yml
application.yml/application.properties file is specific to Spring Boot applications. Unless you change the location of external properties of an application, spring boot will always load application.yml from the following location:
/src/main/resources/application.yml
You can store all the external properties for your application in this file. Common properties that are available in any Spring Boot project can be found at: https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html You can customize these properties as per your application needs. Sample file is shown below:
spring:
application:
name: foobar
datasource:
driverClassName: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost/test
server:
port: 9000
bootstrap.yml
bootstrap.yml on the other hand is specific to spring-cloud-config and is loaded before the application.yml
bootstrap.yml is only needed if you are using Spring Cloud and your microservice configuration is stored on a remote Spring Cloud Config Server.
Important points about bootstrap.yml
spring.application.name: "application-name" spring.cloud.config.server.git.uri: "git-uri-config"
spring.application.name: spring.cloud.config.uri:
Upon startup, Spring Cloud makes an HTTP(S) call to the Spring Cloud Config Server with the name of the application and retrieves back that application’s configuration.
application.yml contains the default configuration for the microservice and any configuration retrieved (from cloud config server) during the bootstrap process will override configuration defined in application.yml
Another option is to pass the single quote as an awk variable:
awk -v q=\' 'BEGIN {FS=" ";} {printf "%s%s%s ", q, $1, q}'
Simpler example with string concatenation:
# Prints 'test me', *including* the single quotes.
$ awk -v q=\' '{print q $0 q }' <<<'test me'
'test me'
This is probably the simplest way:
data$rownumber = 1:dim(data)[1]
It's probably worth noting that if you want to select a row by its row index, you can do this with simple bracket notation
data[3,]
vs.
data[data$rownumber==3,]
So I'm not really sure what this new column accomplishes.
One more method (bulletproof) taken from here utilizing 'display:table' rule:
Markup
<div class="container">
<div class="outer">
<div class="inner">
<div class="centered">
...
</div>
</div>
</div>
</div>
CSS:
.outer {
display: table;
width: 100%;
height: 100%;
}
.inner {
display: table-cell;
vertical-align: middle;
text-align: center;
}
.centered {
position: relative;
display: inline-block;
width: 50%;
padding: 1em;
background: orange;
color: white;
}
This is working code
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
DropDownList1.DataTextField = "user_name";
DropDownList1.DataValueField = "user_id";
DropDownList1.DataSource = getData();// get the data into the list you can set it
DropDownList1.DataBind();
DropDownList1.SelectedIndex = DropDownList1.Items.IndexOf(DropDownList1.Items.FindByText("your default selected text"));
}
}
Your code "for /f "tokens=* delims=" %%x in (a.txt) do echo %%x" will work on most Windows Operating Systems unless you have modified commands.
So you could instead "cd" into the directory to read from before executing the "for /f" command to follow out the string. For instance if the file "a.txt" is located at C:\documents and settings\%USERNAME%\desktop\a.txt then you'd use the following.
cd "C:\documents and settings\%USERNAME%\desktop"
for /f "tokens=* delims=" %%x in (a.txt) do echo %%x
echo.
echo.
echo.
pause >nul
exit
But since this doesn't work on your computer for x reason there is an easier and more efficient way of doing this. Using the "type" command.
@echo off
color a
cls
cd "C:\documents and settings\%USERNAME%\desktop"
type a.txt
echo.
echo.
pause >nul
exit
Or if you'd like them to select the file from which to write in the batch you could do the following.
@echo off
:A
color a
cls
echo Choose the file that you want to read.
echo.
echo.
tree
echo.
echo.
echo.
set file=
set /p file=File:
cls
echo Reading from %file%
echo.
type %file%
echo.
echo.
echo.
set re=
set /p re=Y/N?:
if %re%==Y goto :A
if %re%==y goto :A
exit
Just wrap floated elements in a <div>
and give it this CSS:
.wrapper {
display: table;
margin: auto;
}
The reason you are getting the unexpected result is that hist(...)
calculates the distribution from a numeric vector. In your code, table(animalFactor)
behaves like a numeric vector with three elements: 1, 3, 7. So hist(...)
plots the number of 1's (1), the number of 3's (1), and the number of 7's (1). @Roland's solution is the simplest.
Here's a way to do this using ggplot
:
library(ggplot2)
ggp <- ggplot(data.frame(animals),aes(x=animals))
# counts
ggp + geom_histogram(fill="lightgreen")
# proportion
ggp + geom_histogram(fill="lightblue",aes(y=..count../sum(..count..)))
You would get precisely the same result using animalFactor
instead of animals
in the code above.
All of the top ranked answers above are accurate and should work for most cases. In the event that they don't as was in my case, I simply got rid of my ~/.ssh/known_hosts
file on the machine I was trying to ssh from and that solved the problem for me. I was able to connect afterwards.
I would either one of the following:
Application.Exit();
for a winform or
Environment.Exit(0);
for a console application (works on winforms too).
Thanks!
"std" is a namespace used for STL (Standard Template Library). Please refer to https://en.wikipedia.org/wiki/Namespace#Use_in_common_languages
You can either write using namespace std;
before using any stl functions, variables or just insert std::
before them.
You'll find one in
http://commons.apache.org/lang/
It's called
org.apache.commons.lang.time.StopWatch
But it roughly does the same as yours. If you're in for more precision, use
System.nanoTime()

So after a number of tries, I found it working.

I often want different columns to have different formats. Here is how I print a simple 2D array using some variety in the formatting by converting (slices of) my NumPy array to a tuple:
import numpy as np
dat = np.random.random((10,11))*100 # Array of random values between 0 and 100
print(dat) # Lines get truncated and are hard to read
for i in range(10):
print((4*"%6.2f"+7*"%9.4f") % tuple(dat[i,:]))
I got the same error after enabling TLSv1.2 in webmin. Right after I enabled TLSv1.2 by accident thinking it was SSLv2, I was not able to log in from https://myipaddress:10000 like I did before. I found this link http://smallbusiness.chron.com/disable-ssl-webmin-miniserv-60053.html and it helped me because I was able to access webmin config file and I was able TLSv1.2
NameValueCollection nvclc = Request.Form;
string uName= nvclc ["txtUserName"];
string pswod= nvclc ["txtPassword"];
//try login
CheckLogin(uName, pswod);
Never mind, I found the answer.
This will do the trick.
Dim colIndex As Long
colIndex = Application.Match(colName, Range(Cells(rowIndex, 1), Cells(rowIndex, 100)), 0)
Try this,
$('td').click(function(){
var row_index = $(this).parent().index();
var col_index = $(this).index();
});
If you need the index of table contain td then you can change it to
var row_index = $(this).parent('table').index();
There is no problem at all using Jupyter with existing or new Python .py modules. With Jupyter running, simply fire up Spyder (or any editor of your choice) to build / modify your module class definitions in a .py file, and then just import the modules as needed into Jupyter.
One thing that makes this really seamless is using the autoreload magic extension. You can see documentation for autoreload here:
http://ipython.readthedocs.io/en/stable/config/extensions/autoreload.html
Here is the code to automatically reload the module any time it has been modified:
# autoreload sets up auto reloading of modified .py modules
import autoreload
%load_ext autoreload
%autoreload 2
Note that I tried the code mentioned in a prior reply to simulate loading .ipynb files as modules, and got it to work, but it chokes when you make changes to the .ipynb file. It looks like you need to restart the Jupyter development environment in order to reload the .ipynb 'module', which was not acceptable to me since I am making lots of changes to my code.
use "Content-type: application/x-www-form-urlencoded" instead of "application/json"
$apply
should be called?TL;DR:
$apply
should be called whenever you want to apply changes made outside of Angular world.
Just to update @Dustin's answer, here is an explanation of what $apply exactly does and why it works.
$apply()
is used to execute an expression in AngularJS from outside of the AngularJS framework. (For example from browser DOM events, setTimeout, XHR or third party libraries). Because we are calling into the AngularJS framework we need to perform proper scope life cycle of exception handling, executing watches.
Angular allows any value to be used as a binding target. Then at the end of any JavaScript code turn, it checks to see if the value has changed.
That step that checks to see if any binding values have changed actually has a method, $scope.$digest()
1. We almost never call it directly, as we use $scope.$apply()
instead (which will call $scope.$digest
).
Angular only monitors variables used in expressions and anything inside of a $watch
living inside the scope. So if you are changing the model outside of the Angular context, you will need to call $scope.$apply()
for those changes to be propagated, otherwise Angular will not know that they have been changed thus the binding will not be updated2.
In my case I created a database and gave the collation 'utf8_general_ci' but the required collation was 'latin1'. After changing my collation type to latin1_bin the error was gone.
The windows equivalent to a cron job is a scheduled task.
A scheduled task can be created as described by Alex and Rudu, but it can also be done command line with schtasks
(if you for instance need to script it or add it to version control).
An example:
schtasks /create /tn calculate /tr calc /sc weekly /d MON /st 06:05 /ru "System"
Creates the task calculate, which starts the calculator(calc) every monday at 6:05 (should you ever need that.)
All available commands can be found here: http://technet.microsoft.com/en-us/library/cc772785%28WS.10%29.aspx
It works on windows server 2008 as well as windows server 2003.
You could use CAST or CONVERT:
SELECT CAST(MyVarcharCol AS INT) FROM Table
SELECT CONVERT(INT, MyVarcharCol) FROM Table
If you just want to suppress warnings from a function, you can add an @
sign in front:
<?php @function_that_i_dont_want_to_see_errors_from(parameters); ?>
The answers given above are all perfectly fine for going up one or two directory levels, but they may get a bit cumbersome if one needs to traverse the directory tree by many levels (say, 5 or 10). This can be done concisely by joining a list of N
os.pardir
s in os.path.join
. Example:
import os
# Create list of ".." times 5
upup = [os.pardir]*5
# Extract list as arguments of join()
go_upup = os.path.join(*upup)
# Get abspath for current file
up_dir = os.path.abspath(os.path.join(__file__, go_upup))
The setCenter() method is still applicable for latest version of Maps API for Flash where fitBounds() does not exist.
You can do like this:
head, tail = os.path.split(url)
Where tail will be your file name.
Excerpted from Josh Stodola's Setting keyboard caret Position in a Textbox or TextArea with Javascript
A generic function that will allow you to insert the caret at any position of a textbox or textarea that you wish:
function setCaretPosition(elemId, caretPos) {
var elem = document.getElementById(elemId);
if(elem != null) {
if(elem.createTextRange) {
var range = elem.createTextRange();
range.move('character', caretPos);
range.select();
}
else {
if(elem.selectionStart) {
elem.focus();
elem.setSelectionRange(caretPos, caretPos);
}
else
elem.focus();
}
}
}
The first expected parameter is the ID of the element you wish to insert the keyboard caret on. If the element is unable to be found, nothing will happen (obviously). The second parameter is the caret positon index. Zero will put the keyboard caret at the beginning. If you pass a number larger than the number of characters in the elements value, it will put the keyboard caret at the end.
Tested on IE6 and up, Firefox 2, Opera 8, Netscape 9, SeaMonkey, and Safari. Unfortunately on Safari it does not work in combination with the onfocus event).
An example of using the above function to force the keyboard caret to jump to the end of all textareas on the page when they receive focus:
function addLoadEvent(func) {
if(typeof window.onload != 'function') {
window.onload = func;
}
else {
if(func) {
var oldLoad = window.onload;
window.onload = function() {
if(oldLoad)
oldLoad();
func();
}
}
}
}
// The setCaretPosition function belongs right here!
function setTextAreasOnFocus() {
/***
* This function will force the keyboard caret to be positioned
* at the end of all textareas when they receive focus.
*/
var textAreas = document.getElementsByTagName('textarea');
for(var i = 0; i < textAreas.length; i++) {
textAreas[i].onfocus = function() {
setCaretPosition(this.id, this.value.length);
}
}
textAreas = null;
}
addLoadEvent(setTextAreasOnFocus);
In hibernate.cfg.xml , please put following code
<mapping class="class/bo name"/>
Content of script.r
:
#!/usr/bin/env Rscript
args = commandArgs(trailingOnly = TRUE)
message(sprintf("Hello %s", args[1L]))
The first line is the shebang line. It’s best practice to use /usr/bin/env Rscript
instead of hard-coding the path to your R installation. Otherwise you risk your script breaking on other computers.
Next, make it executable (on the command line):
chmod +x script.r
Invocation from command line:
./script.r world
# Hello world
Using only the standard library with minimal code!
thread {
val jsonStr = try { URL(url).readText() } catch (ex: Exception) { return@thread }
runOnUiThread { displayOrWhatever(jsonStr) }
}
This starts a GET request on a new thread, leaving the UI thread to respond to user input. However, we can only modify UI elements from the main/UI thread, so we actually need a runOnUiThread
block to show the result to our user. This enqueues our display code to be run on the UI thread soon.
The try/catch is there so your app won't crash if you make a request with your phone's internet off. Add your own error handling (e.g. showing a Toast) as you please.
.readText()
is not part of the java.net.URL
class but a Kotlin extension method, Kotlin "glues" this method onto URL
. This is enough for plain GET requests, but for more control and POST requests you need something like the Fuel
library.
Going to keep this pithier, this is already asked and answered above .
I'd step back however and answer it slightly differently, the docker engine itself adds orchestration as one of its extras and this is the disruptive part. Once you start running an app as a combination of containers running 'somewhere' across multiple container engines it gets really exciting. Robustness, Horizontal Scaling, complete abstraction from the underlying hardware, i could go on and on...
Its not just Docker that gives you this, in fact the de facto Container Orchestration standard is Kubernetes which comes in a lot of flavours, a Docker one, but also OpenShift, SuSe, Azure, AWS...
Then beneath K8S there are alternative container engines; the interesting ones are Docker and CRIO - recently built, daemonless, intended as a container engine specifically for Kubernetes but immature. Its the competition between these that I think will be the real long term choice for a container engine.
As @djikay mentioned, you cannot pass multiple FromBody
parameters.
One workaround I have is to define a CompositeObject
,
public class CompositeObject
{
public Content Content { get; set; }
public Config Config { get; set; }
}
and have your WebAPI takes this CompositeObject
as the parameter instead.
public void StartProcessiong([FromBody] CompositeObject composite)
{ ... }
There is no portable way to read raw characters from a Java console.
Some platform-dependent workarounds have been presented above. But to be really portable, you'd have to abandon console mode and use a windowing mode, e.g. AWT or Swing.
We can find these by looking at Bootstrap's stylesheet, Bootstrap.css. Each \{number}
represents a hexadecimal value, so \2a
is equal to 0x2a

If you're using lodash:
_.endsWith('abc', 'c'); // true
If not using lodash, you can borrow from its source.
You should use the title attribute for anchor tags if you wish to apply descriptive information similarly as you would for an alt attribute. The title attribute is valid on anchor tags and is serves no other purpose than providing information about the linked page.
W3C recommends that the value of the title attribute should match the value of the title of the linked document but it's not mandatory.
http://www.w3.org/MarkUp/1995-archive/Elements/A.html
Alternatively, and likely to be more beneficial, you can use the ARIA accessibility attribute aria-label
(not to be confused with aria-labeledby
). aria-label
serves the same function as the alt attribute does for images but for non-image elements and includes some measure of optimization since your optimizing for screen readers.
http://www.w3.org/WAI/GL/wiki/Using_aria-label_to_provide_labels_for_objects
If you want to describe an anchor tag though, it's usually appropriate to use the rel or rev tag but your limited to specific values, they should not be used for human readable descriptions.
Rel serves to describe the relationship of the linked page to the current page. (e.g. if the linked page is next in a logical series it would be rel=next)
The rev attribute is essentially the reverse relationship of the rel attribute. Rev describes the relationship of the current page to the linked page.
You can find a list of valid values here: http://microformats.org/wiki/existing-rel-values
if you still need to use the double-colon then make sure your on PHP 5.3+
Here's what worked for me in C#, firefoxDriver is global to the class:
in the usings:
using System.Drawing;
using System.Windows.Forms;
in the code:
this.firefoxDriver = new FirefoxDriver();
this.firefoxDriver.Manage().Window.Position = new Point(0, 0);
this.firefoxDriver.Manage().Window.Size = new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height);
CreateImage(size, depth, channels)
https://opencv.willowgarage.com/documentation/python/core_operations_on_arrays.html#CreateImage
That's as easy as
IsNull(FieldName, 0)
Or more completely:
SELECT iar.Description,
ISNULL(iai.Quantity,0) as Quantity,
ISNULL(iai.Quantity * rpl.RegularPrice,0) as 'Retail',
iar.Compliance
FROM InventoryAdjustmentReason iar
LEFT OUTER JOIN InventoryAdjustmentItem iai on (iar.Id = iai.InventoryAdjustmentReasonId)
LEFT OUTER JOIN Item i on (i.Id = iai.ItemId)
LEFT OUTER JOIN ReportPriceLookup rpl on (rpl.SkuNumber = i.SkuNo)
WHERE iar.StoreUse = 'yes'
A CASE
expression returns a value from the THEN
portion of the clause. You could use it thusly:
SELECT *
FROM sys.indexes i
JOIN sys.partitions p
ON i.index_id = p.index_id
JOIN sys.allocation_units a
ON CASE
WHEN a.type IN (1, 3) AND a.container_id = p.hobt_id THEN 1
WHEN a.type IN (2) AND a.container_id = p.partition_id THEN 1
ELSE 0
END = 1
Note that you need to do something with the returned value, e.g. compare it to 1. Your statement attempted to return the value of an assignment or test for equality, neither of which make sense in the context of a CASE
/THEN
clause. (If BOOLEAN
was a datatype then the test for equality would make sense.)
You can specify JsonSerializerSettings
for each JsonConvert
, and you can set a global default.
Single JsonConvert
with an overload:
// Option #1.
JsonSerializerSettings config = new JsonSerializerSettings { ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore };
this.json = JsonConvert.SerializeObject(YourObject, Formatting.Indented, config);
// Option #2 (inline).
JsonConvert.SerializeObject(YourObject, Formatting.Indented,
new JsonSerializerSettings() {
ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
}
);
Global Setting with code in Application_Start()
in Global.asax.cs:
JsonConvert.DefaultSettings = () => new JsonSerializerSettings {
Formatting = Newtonsoft.Json.Formatting.Indented,
ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
};

Seems like I can just set the CSS for the select
in Chrome directly. CSS and HTML code provided below :
.boldoption {_x000D_
font-weight: bold;_x000D_
}
_x000D_
<select>_x000D_
<option>Some normal-font option</option>_x000D_
<option>Another normal-font option</option>_x000D_
<option class="boldoption">Some bold option</option>_x000D_
</select>

If any of these answers above don't work, and you're on an apache server, adding the following to your .htaccess file:
//most of the common formats, add any that apply
AddType video/mp4 .mp4
AddType audio/mp4 .m4a
AddType video/mp4 .m4v
AddType video/ogg .ogv
AddType video/ogg .ogg
AddType video/webm .webm
I had a similar problem and adding this solved all my playback issues.
The second method, Task.Run
, has been introduced in a later version of the .NET framework (in .NET 4.5).
However, the first method, Task.Factory.StartNew
, gives you the opportunity to define a lot of useful things about the thread you want to create, while Task.Run
doesn't provide this.
For instance, lets say that you want to create a long running task thread. If a thread of the thread pool is going to be used for this task, then this could be considered an abuse of the thread pool.
One thing you could do in order to avoid this would be to run the task in a separate thread. A newly created thread that would be dedicated to this task and would be destroyed once your task would have been completed. You cannot achieve this with the Task.Run
, while you can do so with the Task.Factory.StartNew
, like below:
Task.Factory.StartNew(..., TaskCreationOptions.LongRunning);
As it is stated here:
So, in the .NET Framework 4.5 Developer Preview, we’ve introduced the new Task.Run method. This in no way obsoletes Task.Factory.StartNew, but rather should simply be thought of as a quick way to use Task.Factory.StartNew without needing to specify a bunch of parameters. It’s a shortcut. In fact, Task.Run is actually implemented in terms of the same logic used for Task.Factory.StartNew, just passing in some default parameters. When you pass an Action to Task.Run:
Task.Run(someAction);
that’s exactly equivalent to:
Task.Factory.StartNew(someAction,
CancellationToken.None, TaskCreationOptions.DenyChildAttach, TaskScheduler.Default);
Another way to solve this issue (I did it on Ubuntu 16.04 but it might also work for windows and other Ubuntu versions):
While going through the installation steps, when you reach the step where you choose which packages to install via check boxes, instead of just pressing next with the default "Tools" checkbox selected also check the box for the version of QT you would like in addition to the "Tools" box. I usually check the first box which is the latest version of QT.
After doing this you should not see the "no valid kits found" issue described in this thread.
Happy Coding.
First remove super.onBackPressed();
from onbackPressed()
method than and below code:
@Override
public void onBackPressed() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Are you sure you want to exit?")
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
MyActivity.this.finish();
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
To add to the (really good) existing answer
open_basedir
is one that can stump you because it can be specified in a web server configuration. While this is easily remedied if you run your own dedicated server, there are some shared hosting software packages out there (like Plesk, cPanel, etc) that will configure a configuration directive on a per-domain basis. Because the software builds the configuration file (i.e. httpd.conf
) you cannot change that file directly because the hosting software will just overwrite it when it restarts.
With Plesk, they provide a place to override the provided httpd.conf
called vhost.conf
. Only the server admin can write this file. The configuration for Apache looks something like this
<Directory /var/www/vhosts/domain.com>
<IfModule mod_php5.c>
php_admin_flag engine on
php_admin_flag safe_mode off
php_admin_value open_basedir "/var/www/vhosts/domain.com:/tmp:/usr/share/pear:/local/PEAR"
</IfModule>
</Directory>
Have your server admin consult the manual for the hosting and web server software they use.
It's important to note that executing a file through your web server is very different from a command line or cron job execution. The big difference is that your web server has its own user and permissions. For security reasons that user is pretty restricted. Apache, for instance, is often apache
, www-data
or httpd
(depending on your server). A cron job or CLI execution has whatever permissions that the user running it has (i.e. running a PHP script as root will execute with permissions of root).
A lot of times people will solve a permissions problem by doing the following (Linux example)
chmod 777 /path/to/file
This is not a smart idea, because the file or directory is now world writable. If you own the server and are the only user then this isn't such a big deal, but if you're on a shared hosting environment you've just given everyone on your server access.
What you need to do is determine the user(s) that need access and give only those them access. Once you know which users need access you'll want to make sure that
That user owns the file and possibly the parent directory (especially the parent directory if you want to write files). In most shared hosting environments this won't be an issue, because your user should own all the files underneath your root. A Linux example is shown below
chown apache:apache /path/to/file
The user, and only that user, has access. In Linux, a good practice would be chmod 600
(only owner can read and write) or chmod 644
(owner can write but everyone can read)
You can read a more extended discussion of Linux/Unix permissions and users here
You can try something like process.argv
, that is if you are using node.js
to run the program.
console.log(process.argv)
=> Would print an array containing
[
'/usr/bin/node',
'/home/user/path/filename.js',
'your_input'
]
You get the user provided input via array index, i.e., console.log(process.argv[3])
This should provide you with the input which you can store.
Example:
var somevariable = process.argv[3]; // input one
var somevariable2 = process.argv[4]; // input two
console.log(somevariable);
console.log(somevariable2);
If you are building a command-line program then the npm package yargs would be really helpful.
This way you get the intersection of two lists and also get the common duplicates.
>>> from collections import Counter
>>> a = Counter([1,2,3,4,5])
>>> b = Counter([1,3,5,6])
>>> a &= b
>>> list(a.elements())
[1, 3, 5]
For Windows/Linux, you can go to File
-> Settings
-> Editor
-> General
-> Auto Import
-> Java
and make the following changes:
change Insert imports on paste
value to All
markAdd unambigious imports on the fly
option as checked
On a Mac, do the same thing in Android Studio
-> Preferences
After this, all unambiguous imports will be added automatically.

if c:
sys.exit(1)

Converting Current DateTime in UTC:
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
DateTimeZone dateTimeZone = DateTimeZone.getDefault(); //Default Time Zone
DateTime currDateTime = new DateTime(); //Current DateTime
long utcTime = dateTimeZone.convertLocalToUTC(currDateTime .getMillis(), false);
String currTime = formatter.print(utcTime); //UTC time converted to string from long in format of formatter
currDateTime = formatter.parseDateTime(currTime); //Converted to DateTime in UTC
I use ? (0x25B8) for the right arrow, often to show a collapsed list; and I pair it with ? (0x25BE) to show the list opened up. Both are unobtrusive.
You need to link with the math library:
gcc -o sphere sphere.c -lm
The error you are seeing: error: ld returned 1 exit status
is from the linker ld
(part of gcc that combines the object files) because it is unable to find where the function pow
is defined.
Including math.h
brings in the declaration of the various functions and not their definition. The def is present in the math library libm.a
. You need to link your program with this library so that the calls to functions like pow() are resolved.
I fixed similar issues by qutating column name
SELECT * from table_name where "foo" is NULL;
In my case it was just
SELECT id, "foo" from table_name;
without quotes i'v got same error.

There are several tools for converting Matlab to Python code.
The only one that's seen recent activity (last commit from June 2018) is Small Matlab to Python compiler (also developed here: SMOP@chiselapp).
Other options include:
Also, for those interested in an interface between the two languages and not conversion:
pymatlab
: communicate from Python by sending data to the MATLAB workspace, operating on them with scripts and pulling back the resulting data.pymat2
: continuation of the seemingly abandoned PyMat.mlabwrap
, mlabwrap-purepy: make Matlab look like Python library (based on PyMat).oct2py
: run GNU Octave commands from within Python.pymex
: Embeds the Python Interpreter in Matlab, also on File Exchange.matpy
: Access MATLAB in various ways: create variables, access .mat files, direct interface to MATLAB engine (requires MATLAB be installed).Btw might be helpful to look here for other migration tips:
On a different note, though I'm not a fortran
fan at all, for people who might find it useful there is:
Does this work for you:
#include <iostream>
#include <list>
#include <boost/range/begin.hpp>
#include <boost/range/end.hpp>
#include <boost/range/iterator_range.hpp>
int main(int argc, char* argv[]){
typedef std::list<int> Nums;
typedef Nums::iterator NumIt;
typedef boost::range_reverse_iterator<Nums>::type RevNumIt;
typedef boost::iterator_range<NumIt> irange_1;
typedef boost::iterator_range<RevNumIt> irange_2;
Nums n = {1, 2, 3, 4, 5, 6, 7, 8};
irange_1 r1 = boost::make_iterator_range( boost::begin(n), boost::end(n) );
irange_2 r2 = boost::make_iterator_range( boost::end(n), boost::begin(n) );
// prints: 1 2 3 4 5 6 7 8
for(auto e : r1)
std::cout << e << ' ';
std::cout << std::endl;
// prints: 8 7 6 5 4 3 2 1
for(auto e : r2)
std::cout << e << ' ';
std::cout << std::endl;
return 0;
}
Edit: This is a more complete version that shows more differences between [
(aka test
) and [[
.
The following table shows that whether a variable is quoted or not, whether you use single or double brackets and whether the variable contains only a space are the things that affect whether using a test with or without -n/-z
is suitable for checking a variable.
| 1a 2a 3a 4a 5a 6a | 1b 2b 3b 4b 5b 6b

digit| true true true true false false| true true true true false false

Fne | false true -err- true -err- false| true true true true false false
If you want to know if a variable is non-zero length, do any of the following:
-n
and quote the variable in single brackets (column 4a)-n
(columns 1b - 4b)Notice in column 1a starting at the row labeled "two" that the result indicates that [
is evaluating the contents of the variable as if they were part of the conditional expression (the result matches the assertion implied by the "T" or "F" in the description column). When [[
is used (column 1b), the variable content is seen as a string and not evaluated.
The errors in columns 3a and 5a are caused by the fact that the variable value includes a space and the variable is unquoted. Again, as shown in columns 3b and 5b, [[
evaluates the variable's contents as a string.
Correspondingly, for tests for zero-length strings, columns 6a, 5b and 6b show the correct ways to do that. Also note that any of these tests can be negated if negating shows a clearer intent than using the opposite operation. For example: if ! [[ -n $var ]]
.
If you're using [
, the key to making sure that you don't get unexpected results is quoting the variable. Using [[
, it doesn't matter.
The error messages, which are being suppressed, are "unary operator expected" or "binary operator expected".
This is the script that produced the table above.

Further to this, the return type is determined by
What the HTTP Request says it wants - in its Accept header. Try looking at the initial request as see what Accept is set to.
What HttpMessageConverters Spring sets up. Spring MVC will setup converters for XML (using JAXB) and JSON if Jackson libraries are on he classpath.
If there is a choice it picks one - in this example, it happens to be JSON.
This is covered in the course notes. Look for the notes on Message Convertors and Content Negotiation.

If you're using SQL Server 2008, there's a new featured called a User Defined Table Type. Here is an example of how to use it:
Create your User Defined Table Type:
CREATE TYPE [dbo].[StringList] AS TABLE(
[Item] [NVARCHAR](MAX) NULL
);
Next you need to use it properly in your stored procedure:
CREATE PROCEDURE [dbo].[sp_UseStringList]
@list StringList READONLY
AS
BEGIN
-- Just return the items we passed in
SELECT l.Item FROM @list l;
END
Finally here's some sql to use it in c#:
using (var con = new SqlConnection(connstring))
{
con.Open();
using (SqlCommand cmd = new SqlCommand("exec sp_UseStringList @list", con))
{
using (var table = new DataTable()) {
table.Columns.Add("Item", typeof(string));
for (int i = 0; i < 10; i++)
table.Rows.Add("Item " + i.ToString());
var pList = new SqlParameter("@list", SqlDbType.Structured);
pList.TypeName = "dbo.StringList";
pList.Value = table;
cmd.Parameters.Add(pList);
using (var dr = cmd.ExecuteReader())
{
while (dr.Read())
Console.WriteLine(dr["Item"].ToString());
}
}
}
}
To execute this from SSMS
DECLARE @list AS StringList
INSERT INTO @list VALUES ('Apple')
INSERT INTO @list VALUES ('Banana')
INSERT INTO @list VALUES ('Orange')
-- Alternatively, you can populate @list with an INSERT-SELECT
INSERT INTO @list
SELECT Name FROM Fruits
EXEC sp_UseStringList @list
It doesn't?
>>> "abc".__len__()

You can turn the values of an Object into an array and test that a string is present. It assumes that the Object is not nested and the string is an exact match:
var obj = { a: 'test1', b: 'test2' };
if (Object.values(obj).indexOf('test1') > -1) {
console.log('has test1');
}

You can use the CSVToArray() function mentioned in this blog entry.
<script type="text/javascript">
// ref: http://stackoverflow.com/a/1293163/2343
// This will parse a delimited string into an array of
// arrays. The default delimiter is the comma, but this
// can be overriden in the second argument.
function CSVToArray( strData, strDelimiter ){
// Check to see if the delimiter is defined. If not,
// then default to comma.
strDelimiter = (strDelimiter || ",");
// Create a regular expression to parse the CSV values.
var objPattern = new RegExp(
(
// Delimiters.
"(\\" + strDelimiter + "|\\r?\\n|\\r|^)" +
// Quoted fields.
"(?:\"([^\"]*(?:\"\"[^\"]*)*)\"|" +
// Standard fields.
"([^\"\\" + strDelimiter + "\\r\\n]*))"
),
"gi"
);
// Create an array to hold our data. Give the array
// a default empty first row.
var arrData = [[]];
// Create an array to hold our individual pattern
// matching groups.
var arrMatches = null;
// Keep looping over the regular expression matches
// until we can no longer find a match.
while (arrMatches = objPattern.exec( strData )){
// Get the delimiter that was found.
var strMatchedDelimiter = arrMatches[ 1 ];
// Check to see if the given delimiter has a length
// (is not the start of string) and if it matches
// field delimiter. If id does not, then we know
// that this delimiter is a row delimiter.
if (
strMatchedDelimiter.length &&
strMatchedDelimiter !== strDelimiter
){
// Since we have reached a new row of data,
// add an empty row to our data array.
arrData.push( [] );
}
var strMatchedValue;
// Now that we have our delimiter out of the way,
// let's check to see which kind of value we
// captured (quoted or unquoted).
if (arrMatches[ 2 ]){
// We found a quoted value. When we capture
// this value, unescape any double quotes.
strMatchedValue = arrMatches[ 2 ].replace(
new RegExp( "\"\"", "g" ),
"\""
);
} else {
// We found a non-quoted value.
strMatchedValue = arrMatches[ 3 ];
}
// Now that we have our value string, let's add
// it to the data array.
arrData[ arrData.length - 1 ].push( strMatchedValue );
}
// Return the parsed data.
return( arrData );
}

I believe the Id column in your SQL Table isn't a identity column.
I've tried different numbers, and it always acts as if the 0s aren't there and sorts the numbers correctly otherwise. Anyone know why?
You're getting a lexicographical sort (e.g. convert objects to strings, and sort them in dictionary order), which is the default sort behavior in Javascript:
https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/sort
array.sort([compareFunction])
Parameters
compareFunction
Specifies a function that defines the sort order. If omitted, the array is sorted lexicographically (in dictionary order) according to the string conversion of each element.
In the ECMAscript specification (the normative reference for the generic Javascript), ECMA-262, 3rd ed., section 15.4.4.11, the default sort order is lexicographical, although they don't come out and say it, instead giving the steps for a conceptual sort function that calls the given compare function if necessary, otherwise comparing the arguments when converted to strings:
13. If the argument comparefn is undefined, go to step 16.
14. Call comparefn with arguments x and y.
15. Return Result(14).
16. Call ToString(x).
17. Call ToString(y).
18. If Result(16) < Result(17), return -1.
19. If Result(16) > Result(17), return 1.
20. Return +0.

Series.map
with Series.fillna
If your column contains more strings than only female
and male
, Series.map
will fail in this case since it will return NaN
for other values.
That's why we have to chain it with fillna
:
Example why .map
fails:
df = pd.DataFrame({'female':['male', 'female', 'female', 'male', 'other', 'other']})
female
0 male
1 female
2 female
3 male
4 other
5 other
df['female'].map({'female': '1', 'male': '0'})
0 0
1 1
2 1
3 0
4 NaN
5 NaN
Name: female, dtype: object
For the correct method, we chain map
with fillna
, so we fill the NaN
with values from the original column:
df['female'].map({'female': '1', 'male': '0'}).fillna(df['female'])
0 0
1 1
2 1
3 0
4 other
5 other
Name: female, dtype: object

Perhaps GitHub's support for deploy keys is what you're looking for? To quote that page:
When should I use a deploy key?
Simple, when you have a server that needs pull access to a single private repo. This key is attached directly to the repository instead of to a personal user account.
If that's what you're already trying and it doesn't work, you might want to update your question with more details of the URLs being used, the names and location of the key files, etc.
Now for the technical part: How to use your SSH key with Jenkins?
If you have, say, a jenkins
unix user, you can store your deploy key in ~/.ssh/id_rsa
. When Jenkins tries to clone the repo via ssh, it will try to use that key.
In some setups, you cannot run Jenkins as an own user account, and possibly also cannot use the default ssh key location ~/.ssh/id_rsa
. In such cases, you can create a key in a different location, e.g. ~/.ssh/deploy_key
, and configure ssh
to use that with an entry in ~/.ssh/config
:
Host github-deploy-myproject
HostName github.com
User git
IdentityFile ~/.ssh/deploy_key
IdentitiesOnly yes
Because all you authenticate to all Github repositories using [email protected]
and you don't want the above key to be used for all your connections to Github, we created a host alias github-deploy-myproject. Your clone URL now becomes
git clone github-deploy-myproject:myuser/myproject
and that is also what you put as repository URL into Jenkins.
(Note that you must not put ssh:// in front in order for this to work.)
Use the csv
module:
import csv
with open("test.csv", "r") as f:
reader = csv.reader(f, delimiter="\t")
for i, line in enumerate(reader):
print 'line[{}] = {}'.format(i, line)
Output:
line[0] = ['Year:', 'Dec:', 'Jan:']
line[1] = ['1', '50', '60']
line[2] = ['2', '25', '50']
line[3] = ['3', '30', '30']
line[4] = ['4', '40', '20']
line[5] = ['5', '10', '10']
You can use Dictonary to map Assume Milk,Butter,Chesse are group A (ListA) Water,Beer,Wine are group B
Dictonary<string,List<string>>) dataMap;
dataMap.add("A",ListA);
dataMap.add("B",ListB);
At View , you can foreach Keys in dataMap and process your action
I use the first approach whenever I create a library. There are several advantages of using a typedef'ed enum as a return code.
If the function returns a more complicated output such as an array and it's length you do not need to create arbitrary structures to return.
rc = func(..., int **return_array, size_t *array_length);
It allows for simple, standardized error handling.
if ((rc = func(...)) != API_SUCCESS) {
/* Error Handling */
}
It allows for simple error handling in the library function.
/* Check for valid arguments */
if (NULL == return_array || NULL == array_length)
return API_INVALID_ARGS;
Using a typedef'ed enum also allows for the enum name to be visible in the debugger. This allows for easier debugging without the need to constantly consult a header file. Having a function to translate this enum into a string is helpful as well.
The most important issue regardless of approach used is to be consistent. This applies to function and argument naming, argument ordering and error handling.
JavaScript Promises actually use callback functions to determine what to do after a Promise has been resolved or rejected, therefore both are not fundamentally different. The main idea behind Promises is to take callbacks - especially nested callbacks where you want to perform a sort of actions, but it would be more readable.
This approach worked for me (but the "Back" button will not have the "<" sign):
- (void)viewDidLoad
{
[super viewDidLoad];
UIBarButtonItem* backNavButton = [[UIBarButtonItem alloc] initWithTitle:@"Back"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(backButtonClicked)];
self.navigationItem.leftBarButtonItem = backNavButton;
}
-(void)backButtonClicked
{
// Do something...
AppDelegate* delegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
[delegate.navController popViewControllerAnimated:YES];
}
You can do this like that:
x = list(set(x))
Example: if you do something like that:
x = [1,2,3,4,5,6,7,8,9,10,2,1,6,31,20]
x = list(set(x))
x
you will see the following result:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 31]
There is only one thing you should think of: the resulting list will not be ordered as the original one (will lose the order in the process).
For the fun of it here's an implementation based on the callback approach:
const char* find(const char* s,
const char* e,
int (*pred)(char))
{
while( s != e && !pred(*s) ) ++s;
return s;
}
void split_on_ws(const char* s,
const char* e,
void (*callback)(const char*, const char*))
{
const char* p = s;
while( s != e ) {
s = find(s, e, isspace);
callback(p, s);
p = s = find(s, e, isnotspace);
}
}
void handle_word(const char* s, const char* e)
{
// handle the word that starts at s and ends at e
}
int main()
{
split_on_ws(some_str, some_str + strlen(some_str), handle_word);
}
Instead of turning the formatting off, you can configure it not to join already wrapped lines. Similar to Jitter's response, here's for Eclipse STS:
Properties ? Java Code Style ? Formatter ? Enable project specific settings OR Configure Workspace Settings ? Edit ? Line Wrapping (tab) ? check "Never join already wrapped lines"
Save, apply.
int[] n=new int[5];
for (int i = 0; i < 5; i++)
{
n[i] = i + 100;
}
foreach (int j in n)
{
int i = j - 100;
Console.WriteLine("Element [{0}]={1}", i, j);
i++;
}
Possible reason: The reason can be that this image is currently used by a running container. In such case, you can list running containers, stop the relevant container and then remove the image:
docker ps
docker stop <containerid>
docker rm <containerid>
docker rmi <imageid>
If you cannnot find container by docker ps, you can use this to list all already exited containers and remove them.
docker ps -a | grep 60afe4036d97
docker rm <containerid>
Note: Be careful of deleting all exited containers at once in case you use Volume-Only
containers. These stay in Exit
state, but contains useful data.

Hash tables have higher constants than common map implementations, which become significant for small containers. Max size is 10, 100, or maybe even 1,000 or more? Constants are the same as ever, but O(log n) is close to O(k). (Remember logarithmic complexity is still really good.)
What makes a good hash function depends on your data's characteristics; so if I don't plan on looking at a custom hash function (but can certainly change my mind later, and easily since I typedef damn near everything) and even though defaults are chosen to perform decently for many data sources, I find the ordered nature of map to be enough of a help initially that I still default to map rather than a hash table in that case.
Plus that way you don't have to even think about writing a hash function for other (usually UDT) types, and just write op< (which you want anyway).
What is the young generation?
The Young Generation is where all new objects are allocated and aged. When the young generation fills up, this causes a minor garbage collection. A young generation full of dead objects is collected very quickly. Some survived objects are aged and eventually move to the old generation.
What is the old generation?
The Old Generation is used to store long surviving objects. Typically, a threshold is set for young generation object and when that age is met, the object gets moved to the old generation. Eventually the old generation needs to be collected. This event is called a major garbage collection
What is the permanent generation?
The Permanent generation contains metadata required by the JVM to describe the classes and methods used in the application. The permanent generation is populated by the JVM at runtime based on classes in use by the application.
PermGen has been replaced with Metaspace since Java 8 release.
PermSize & MaxPermSize parameters will be ignored now
How does the three generations interact/relate to each other?
Image source & oracle technetwork tutorial article: http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/gc01/index.html
"The General Garbage Collection Process" in above article explains the interactions between them with many diagrams.

There is this expansion that enables you to show notifications inside HTML page using bootstrap.
It is very easy to implement and it works fine. Here is a github page for the project including some demo images.
Given a staging table with 70 columns and only 4 representing duplicates, this code will return the offending columns:
SELECT
COUNT(*)
,LTRIM(RTRIM(S.TransactionDate))
,LTRIM(RTRIM(S.TransactionTime))
,LTRIM(RTRIM(S.TransactionTicketNumber))
,LTRIM(RTRIM(GrossCost))
FROM Staging.dbo.Stage S
GROUP BY
LTRIM(RTRIM(S.TransactionDate))
,LTRIM(RTRIM(S.TransactionTime))
,LTRIM(RTRIM(S.TransactionTicketNumber))
,LTRIM(RTRIM(GrossCost))
HAVING COUNT(*) > 1
.
SELECT
dp.state_desc + ' '
+ dp.permission_name collate latin1_general_cs_as
+ ISNULL((' ON ' + QUOTENAME(s.name) + '.' + QUOTENAME(o.name)),'')
+ ' TO ' + QUOTENAME(dpr.name)
FROM sys.database_permissions AS dp
LEFT JOIN sys.objects AS o ON dp.major_id=o.object_id
LEFT JOIN sys.schemas AS s ON o.schema_id = s.schema_id
LEFT JOIN sys.database_principals AS dpr ON dp.grantee_principal_id=dpr.principal_id
WHERE dpr.name NOT IN ('public','guest')
Slight change of the accepted answer if you want to grab permissions that are applied at database level in addition to object level. Basically switch to LEFT JOIN
and make sure to handle NULL
for object
and schema
names

I have a local install of tensorflow 1.15.0 (with tensorboard obviously included) on MacOS.
For me, the path to the relevant file within my user directory is Library/Python/3.7/lib/python/site-packages/tensorboard/main.py. So, which
does not work for me, but you have to look for the file named main.py, which is weird since it apparently is named something else for other users.
genrsa
has been replaced by genpkey
& when run manually in a terminal it will prompt for a password:
openssl genpkey -aes-256-cbc -algorithm RSA -out /etc/ssl/private/key.pem -pkeyopt rsa_keygen_bits:4096
However when run from a script the command will not ask for a password so to avoid the password being viewable as a process use a function in a shell
script:
get_passwd() {
local passwd=
echo -ne "Enter passwd for private key: ? "; read -s passwd
openssl genpkey -aes-256-cbc -pass pass:$passwd -algorithm RSA -out $PRIV_KEY -pkeyopt rsa_keygen_bits:$PRIV_KEYSIZE
}
Thanks to https://stackoverflow.com/users/1652962/cimmanon that gave me the answer.
The solution is setting a height to the vertical scrollable element. For example:
#container article {
flex: 1 1 auto;
overflow-y: auto;
height: 0px;
}
The element will have height because flexbox recalculates it unless you want a min-height so you can use height: 100px;
that it is exactly the same as: min-height: 100px;
#container article {
flex: 1 1 auto;
overflow-y: auto;
height: 100px; /* == min-height: 100px*/
}
So the best solution if you want a min-height
in the vertical scroll:
#container article {
flex: 1 1 auto;
overflow-y: auto;
min-height: 100px;
}
If you just want full vertical scroll in case there is no enough space to see the article:
#container article {
flex: 1 1 auto;
overflow-y: auto;
min-height: 0px;
}

The closest validation of my theory i can find it from RFC 4253:
The "ssh-rsa" key format has the following specific encoding:
string "ssh-rsa" mpint e mpint n
Here the 'e' and 'n' parameters form the signature key blob.
But it doesn't explain the length prefixes.

From RFC3447 - Public-Key Cryptography Standards (PKCS) #1: RSA Cryptography Specifications Version 2.1:
A.1.1 RSA public key syntax
An RSA public key should be represented with the ASN.1 type
RSAPublicKey
:RSAPublicKey ::= SEQUENCE { modulus INTEGER, -- n publicExponent INTEGER -- e }
The fields of type RSAPublicKey have the following meanings:
- modulus is the RSA modulus n.
- publicExponent is the RSA public exponent e.
Using Microsoft's excellent (and the only real) ASN.1 documentation:

On server-side it will be not as accurate as with JavaScript. Meanwhile, sometimes it is required to solve such task. Just to share the possible solution in this case I write this answer.
If you need to determine user's time zone it could be done via Geo-IP services. Some of them providing timezone. For example, this one (http://smart-ip.net/geoip-api) could help:
<?php
$ip = $_SERVER['REMOTE_ADDR']; // means we got user's IP address
$json = file_get_contents( 'http://smart-ip.net/geoip-json/' . $ip); // this one service we gonna use to obtain timezone by IP
// maybe it's good to add some checks (if/else you've got an answer and if json could be decoded, etc.)
$ipData = json_decode( $json, true);
if ($ipData['timezone']) {
$tz = new DateTimeZone( $ipData['timezone']);
$now = new DateTime( 'now', $tz); // DateTime object corellated to user's timezone
} else {
// we can't determine a timezone - do something else...
}
function DecimalNumberValidation() {
var amounttext = ;
if (!(/^[-+]?\d*\.?\d*$/.test(document.getElementById('txtRemittanceNumber').value))){
alert('Please enter only numbers into amount textbox.')
}
else
{
alert('Right Number');
}
}
function will validate any decimal number weather number has decimal places or not, it will say "Right Number" other wise "Please enter only numbers into amount textbox." alert message will come up.
Thanks... :)

Moving forward, this might be another reason for you encountering this error.
Path changes appear to be persistent if you set the SHELL variable in your makefile first:
SHELL := /bin/bash

test all:

I don't know if this is desired behavior or not.
