To give specific answer to the Question posed about creating the alias to move the files to Trash folder instead of deleting them:
alias rm="mv "$1" -t ~/.Trash/"
Offcourse you have to create dir ~/.Trash first.
Then just give following command:
$rm <filename>
$rm <dirname>
SELECT employee_id,department_id AS department
FROM employees
order by department
SELECT employee_id,department_id AS "department"
FROM employees
order by department
--error on oracle--
so better to use AS without double quotation if you use ORDER BY clause
Just make sure it is executable, using chmod +x
. By default, the current directory is not on your PATH, so you will need to execute it as ./script.sh
- or otherwise reference it by a qualified path. Alternatively, if you truly need just script.sh
, you would need to add it to your PATH. (You may not have access to modify the system path, but you can almost certainly modify the PATH of your own current environment.) This also assumes that your script starts with something like #!/bin/sh
.
You could also still use an alias, which is not really related to shell scripting but just the shell, and is simple as:
alias script.sh='sh script.sh'
Which would allow you to use just simply script.sh
(literally - this won't work for any other *.sh
file) instead of sh script.sh
.
You can always take the CTE, (Common Tabular Expression), approach.
;WITH updateCTE AS
(
SELECT ID, TITLE
FROM HOLD_TABLE
WHERE ID = 101
)
UPDATE updateCTE
SET TITLE = 'TEST';
Try,
#!/bin/bash
pause ()
{
REPLY=Y
while [ "$REPLY" == "Y" ] || [ "$REPLY" != "y" ]
do
echo -e "\t\tPress 'y' to continue\t\t\tPress 'n' to quit"
read -n1 -s
case "$REPLY" in
"n") exit ;;
"N") echo "case sensitive!!" ;;
"y") clear ;;
"Y") echo "case sensitive!!" ;;
* ) echo "$REPLY is Invalid Option" ;;
esac
done
}
pause
echo "Hi"
SQL Server doesn't allow you to reference the alias in the GROUP BY clause because of the logical order of processing. The GROUP BY clause is processed before the SELECT clause, so the alias is not known when the GROUP BY clause is evaluated. This also explains why you can use the alias in the ORDER BY clause.
Here is one source for information on the SQL Server logical processing phases.
It's possible to effectively define a variable that can be used in both the SELECT, WHERE and other clauses.
A subquery doesn't necessarily allow for appropriate binding to the referenced table columns, however OUTER APPLY does.
SELECT A.identifier
, A.name
, vars.MONTH_NO
, TO_NUMBER(TO_CHAR(B.last_update_date, 'YYYYMM')) as UPD_DATE
FROM table_a A
, table_b B ON A.identifier = B.identifier
OUTER APPLY (
SELECT
-- variables
MONTH_NO = TO_NUMBER(DECODE( A.month_no
, 1, 200803
, 2, 200804
, 3, 200805
, 4, 200806
, 5, 200807
, 6, 200808
, 7, 200809
, 8, 200810
, 9, 200811
, 10, 200812
, 11, 200701
, 12, 200702
, NULL))
) vars
WHERE vars.MONTH_NO > UPD_DATE
Kudos to Syed Mehroz Alam.
To be honest, in practice usually there is not difference between System.String and string.
All types in C# are objects and all derives from System.Object class. One difference is that string is a C# keyword and String you can use as variable name. System.String is conventional .NET name of this type and string is convenient C# name. Here is simple program which presents difference between System.String and string.
string a = new string(new char[] { 'x', 'y', 'z' });
string b = new String(new char[] { 'x', 'y', 'z' });
String c = new string(new char[] { 'x', 'y', 'z' });
String d = new String(new char[] { 'x', 'y', 'z' });
MessageBox.Show((a.GetType() == typeof(String) && a.GetType() == typeof(string)).ToString()); // shows true
MessageBox.Show((b.GetType() == typeof(String) && b.GetType() == typeof(string)).ToString()); // shows true
MessageBox.Show((c.GetType() == typeof(String) && c.GetType() == typeof(string)).ToString()); // shows true
MessageBox.Show((d.GetType() == typeof(String) && d.GetType() == typeof(string)).ToString()); // shows true

public enum Foo : UInt32 { }
is working. I've Visual Studio 2015 Community.
This answer builds upon the answer by johnny. It applies if you're not using git-alias
from git-extras
.
On Linux, run once:
git config --global alias.alias "! git config --get-regexp ^alias\. | sed -e s/^alias\.// -e s/\ /\ =\ /"
This will create a permanent git alias named alias
which gets stored in your ~/.gitconfig
file. Using it will list all of your git aliases, in nearly the same format as they are in the ~/.gitconfig
file. To use it, type:
$ git alias
loga = log --graph --decorate --name-status --all
alias = ! git config --get-regexp ^alias\. | sed -e s/^alias\.// -e s/\ /\ =\ /
The following considerations apply:
To prevent the alias alias
from getting listed as above, append | grep -v ^'alias '
just before the closing double-quote. I don't recommend this so users don't forget that the the command alias
is but an alias and is not a feature of git.
To sort the listed aliases, append | sort
just before the closing double-quote. Alternatively, you can keep the aliases in ~/.gitconfig
sorted.
To add the alias as a system-wide alias, replace --global
(for current user) with --system
(for all users). This typically goes in the /etc/gitconfig
file.
The rubocop gem contributors propose in their Ruby Style Guide:
Prefer alias when aliasing methods in lexical class scope as the resolution of self in this context is also lexical, and it communicates clearly to the user that the indirection of your alias will not be altered at runtime or by any subclass unless made explicit.
class Westerner
def first_name
@names.first
end
alias given_name first_name
end
Always use alias_method when aliasing methods of modules, classes, or singleton classes at runtime, as the lexical scope of alias leads to unpredictability in these cases
module Mononymous
def self.included(other)
other.class_eval { alias_method :full_name, :given_name }
end
end
class Sting < Westerner
include Mononymous
end
You can do this using the WITH clause of the SELECT statement:
;
WITH my_select As (SELECT ... FROM ...)
SELECT * FROM foo
WHERE id IN (SELECT MAX(id) FROM my_select GROUP BY name)
That's the ANSI/ISO SQL Syntax. I know that SQL Server, Oracle and DB2 support it. Not sure about the others...
You need to pass the parameters, try this:
doskey np=notepad++.exe $*
Edit (responding to Romonov's comment) Q: Is there any way I can make the command prompt remember so I don't have to run this each time I open a new command prompt?
doskey
is a textual command that is interpreted by the command processor (e.g. cmd.exe), it can't know to modify state in some other process (especially one that hasn't started yet).
People that use doskey
to setup their initial command shell environments typically use the /K
option (often via a shortcut) to run a batch file which does all the common setup (like- set window's title, colors, etc).
cmd.exe /K env.cmd
env.cmd:
title "Foo Bar"
doskey np=notepad++.exe $*
...
This works in ksh:
$ alias -x mkcd="mkdir \$dirname; cd \$dirname;"
$ alias mkcd
mkcd='mkdir $dirname; cd $dirname;'
$ dirname=aaa
$ pwd
/tmp
$ mkcd
$ pwd
/tmp/aaa
The "-x" option make the alias "exported" - alias is visible in subshells.
And be aware of fact that aliases defined in a script are not visible in that script (because aliases are expanded when a script is loaded, not when a line is interpreted). This can be solved with executing another script file in same shell (using dot).
As others have referred, names in Oracle SQL must be less or equal to 30 characters. I would add that this rule applies not only to table names but to field names as well. So there you have it.
hashCode()
is a unique code which is generated by the JVM for every object creation.
We use hashCode()
to perform some operation on hashing related algorithm like Hashtable, Hashmap etc..
The advantages of hashCode()
make searching operation easy because when we search for an object that has unique code, it helps to find out that object.
But we can't say hashCode()
is the address of an object. It is a unique code generated by JVM for every object.
That is why nowadays hashing algorithm is the most popular search algorithm.
To redirect your logs output to a file, you need to use the FileAppender and need to define other file details in your log4j.properties/xml file. Here is a sample properties file for the same:
# Root logger option
log4j.rootLogger=INFO, file
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=C:\\loging.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

Of course, Object.keys()
is the best way to get an Object's keys. If it's not available in your environment, it can be trivially shimmed using code such as in your example (except you'd need to take into account your loop will iterate over all properties up the prototype chain, unlike Object.keys()
's behaviour).
However, your example code...
var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' };
var keys = [];
for (var key in foo) {
keys.push(key);
}
...could be modified. You can do the assignment right in the variable part.
var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' };
var keys = [], i = 0;
for (keys[i++] in foo) {}
Of course, this behaviour is different to what Object.keys()
actually does (jsFiddle). You could simply use the shim on the MDN documentation.
try:
r = requests.post(url, data=data, verify='/path/to/public_key.pem')
What does res.render do and what does the html file look like?
res.render()
function compiles your template (please don't use ejs), inserts locals there, and creates html output out of those two things.
Answering Edit 2 part.
// here you set that all templates are located in `/views` directory
app.set('views', __dirname + '/views');
// here you set that you're using `ejs` template engine, and the
// default extension is `ejs`
app.set('view engine', 'ejs');
// here you render `orders` template
response.render("orders", {orders: orders_json});
So, the template path is views/
(first part) + orders
(second part) + .ejs
(third part) === views/orders.ejs
Anyway, express.js documentation is good for what it does. It is API reference, not a "how to use node.js" book.
One of the answers in the question referred to by @Z.Bagley gave me the answer. I had to import Renderer2 from @angular/core into my component. Then:

setTimeout(() => element.focus(), 0);
Thank you @MrBlaise for the solution!
I found out how to do this on the Android emulator itself (Menu, "Settings" App - not the settings of the emulator outside). All you need to do is:
open settings app -> Language & Input -> Go to the "Keyboard & Input Methods -> click Default
This will bring up a Dialog in which case you can then disable the Hardware Keyboard by switching the hardware keyboard from on to off. This will disable the Hardware keyboard and enable the softkeyboard.

600dp: a 7” tablet (600x1024 mdpi).
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).
I use this to make more than one layout:

I am writing a GUI for rsync in python, and have the same probelms. This problem has troubled me for several days until i find this in pyDoc.
If universal_newlines is True, the file objects stdout and stderr are opened as text files in universal newlines mode. Lines may be terminated by any of '\n', the Unix end-of-line convention, '\r', the old Macintosh convention or '\r\n', the Windows convention. All of these external representations are seen as '\n' by the Python program.
It seems that rsync will output '\r' when translate is going on.

You have to actually call some method to create the directories. Just creating a file
object will not create the corresponding file or directory on the file system.
You can use File#mkdirs()
method to create the directory: -
theFile.mkdirs();
Difference between File#mkdir()
and File#mkdirs()
is that, the later will create any intermediate directory if it does not exist.

I found this thread among others and I agree it contains the most complete answers so I'm adding mine too:
sed
and ed
are so useful...by hand.
Look at this code from @Johnny:
sed -i -e 's/abc/XYZ/g' /tmp/file.txt
When my restriction is to use it in a shell script, no variable can be used inside in place of "abc" or "XYZ". The BashFAQ seems to agree with what I understand at least. So, I can't use:
x='abc'
y='XYZ'
sed -i -e 's/$x/$y/g' /tmp/file.txt
#or,
sed -i -e "s/$x/$y/g" /tmp/file.txt
but, what can we do? As, @Johnny said use a while read...
but, unfortunately that's not the end of the story. The following worked well with me:
#edit user's virtual domain
result=
#if nullglob is set then, unset it temporarily
is_nullglob=$( shopt -s | egrep -i '*nullglob' )
if [[ is_nullglob ]]; then
shopt -u nullglob
fi
while IFS= read -r line; do
line="${line//'<servername>'/$server}"
line="${line//'<serveralias>'/$alias}"
line="${line//'<user>'/$user}"
line="${line//'<group>'/$group}"
result="$result""$line"'\n'
done < $tmp
echo -e $result > $tmp
#if nullglob was set then, re-enable it
if [[ is_nullglob ]]; then
shopt -s nullglob
fi
#move user's virtual domain to Apache 2 domain directory
......
As one can see if nullglob
is set then, it behaves strangely when there is a string containing a *
as in:
<VirtualHost *:80>
ServerName www.example.com
which becomes
<VirtualHost ServerName www.example.com
there is no ending angle bracket and Apache2 can't even load.
This kind of parsing should be slower than one-hit search and replace but, as you already saw, there are four variables for four different search patterns working out of one parse cycle.
The most suitable solution I can think of with the given assumptions of the problem.
You can access the values in a vector just as you access any other array.
for (int i = 0; i < v.size(); i++)
{
v[i] -= 1;
}

The query below works only when searching for dependencies on a table and not those on a column:

I needed to template a few files with minimal tooling and for me the issue with above sed -e '/../r file.txt
is that it only appends the file after it prints out the rest of the match, it doesn't replace it.
This doesn't do it (all matches are replaced and pattern matching continues from same point)

The non-greedy ?
works perfectly fine. It's just that you need to select dot matches all option in the regex engines (regexpal, the engine you used, also has this option) you are testing with. This is because, regex engines generally don't match line breaks when you use .
. You need to tell them explicitly that you want to match line-breaks too with .
For example,
<img\s.*?>
works fine!
Check the results here.
Also, read about how dot behaves in various regex flavours.
I think this should do the trick:

There is a lot of way to solve this...
One way is set the TrustStore certificates in a keystore file and put it in the path of the application, and set these system properties in the main method:
public static void main(String[] args) {
System.setProperty("javax.net.ssl.trustStore", "trust-store.jks");
System.setProperty("javax.net.ssl.trustStorePassword", "TrustStore");
...
}
Other way is place the keystore as resource file inside the project jar file and load it:
public static SSLContext createSSLContext(String resourcePath, String pass) throws NoSuchAlgorithmException, KeyStoreException, IOException, CertificateException, UnrecoverableKeyException, KeyManagementException {
// initialise the keystore
final char[] password = pass.toCharArray();
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(ThisClass.class.getResourceAsStream(resourcePath
), password);
// Setup the key manager factory.
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, password);
// Setup the trust manager factory.
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
tmf.init(ks);
SSLContext sslc = SSLContext.getInstance("TLS");
sslc.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
return sslc;
}
public static void main(String[] args) {
SSLContext.setDefault(
createSSLContext("/trust-store.jks", "TrustStore"));
...
}
In windows you can try this solution too: https://stackoverflow.com/a/59056537/980442

file in this way:

When you need to accept a function as argument which takes no arguments and returns no result (void), in my opinion it is still best to have something like
public interface Thunk { void apply(); }
somewhere in your code. In my functional programming courses the word 'thunk' was used to describe such functions. Why it isn't in java.util.function is beyond my comprehension.
In other cases I find that even when java.util.function does have something that matches the signature I want - it still doesn't always feel right when the naming of the interface doesn't match the use of the function in my code. I guess it's a similar point that is made elsewhere here regarding 'Runnable' - which is a term associated with the Thread class - so while it may have he signature I need, it is still likely to confuse the reader.

NodeJS Solution:
In Nodejs you can get it via promises...
If you write this code, you can be sure that the page is fully loaded when you get to the then...
driver.get('www.sidanmor.com').then(()=> {
// here the page is fully loaded!!!
// do your stuff...
}).catch(console.log.bind(console));
If you write this code, you will navigate, and selenium will wait 3 seconds...
driver.get('www.sidanmor.com');
driver.sleep(3000);
// you can't be sure that the page is fully loaded!!!
// do your stuff... hope it will be OK...
From Selenium documentation:
this.get( url ) ? Thenable
Schedules a command to navigate to the given URL.
Returns a promise that will be resolved when the document has finished loading.
You can also do this:
const char *longString = R""""(
This is

Now, use OnClick method.
location.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
location.setBackgroundResource(R.drawable.green);
}
});
this changes the button but looks similar to changing the background.
You could break by RETURN
. For example
def a = [1, 2, 3, 4, 5, 6, 7]
def ret = 0
a.each {def n ->
if (n > 5) {
ret = n
return ret
}
}
It works for me!
Create Bean for Rest Template to auto wiring the Rest Template object.
@SpringBootApplication
public class ChatAppApplication {
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
public static void main(String[] args) {
SpringApplication.run(ChatAppApplication.class, args);
}
}
Consume the GET/POST API by using RestTemplate - exchange() method. Below is for the post api which is defined in the controller.
@RequestMapping(value = "/postdata",method = RequestMethod.POST)
public String PostData(){
return "{\n" +
" \"value\":\"4\",\n" +
" \"name\":\"David\"\n" +
"}";
}
@RequestMapping(value = "/post")
public String getPostResponse(){
HttpHeaders headers=new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
HttpEntity<String> entity=new HttpEntity<String>(headers);
return restTemplate.exchange("http://localhost:8080/postdata",HttpMethod.POST,entity,String.class).getBody();
}

It is 2020 December. The same problem came to me in a different way. When I was going to Deploy in google play store, it said I have to create the bundle higher than android v28 and I updated my projects Compile using Android Version 30 (in Xamarin Android project properties). It was not possible to do it with the same error (Android support library has no support for V7). I tried everything mentioned above and was not working and here is what worked for me. I was using this in splashactivity.cs
using Android.Support.V7.App;
And it is the one giving the trouble and i changed it into V4
using Android.Support.V4.App;
then AppCompatActivity was underlined red and I had to get androidx appcompat app as follows
using AndroidX.AppCompat.App;
Now it is working and it may help someone else too.

You need to pass it as an extra:
String easyPuzzle = "630208010200050089109060030"+
"008006050000187000060500900"+
"09007010681002000502003097";
Intent i = new Intent(this, ToClass.class);
i.putExtra("epuzzle", easyPuzzle);
startActivity(i);
Then extract it from your new activity like this:
Intent intent = getIntent();
String easyPuzzle = intent.getExtras().getString("epuzzle");

As a twist of the accepted answer (https://stackoverflow.com/a/255638/986160) assuming that the keys will be associated with signle values in the dictionary. Similar to (https://stackoverflow.com/a/255630/986160) but a bit more elegant. The novelty is in that the consuming class can be used as an enumeration alternative (but for strings too) and that the dictionary implements IEnumerable.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;
namespace MyApp.Dictionaries
{
class BiDictionary<TFirst, TSecond> : IEnumerable
{
IDictionary<TFirst, TSecond> firstToSecond = new Dictionary<TFirst, TSecond>();
IDictionary<TSecond, TFirst> secondToFirst = new Dictionary<TSecond, TFirst>();
public void Add(TFirst first, TSecond second)
{
firstToSecond.Add(first, second);
secondToFirst.Add(second, first);
}
public TSecond this[TFirst first]
{
get { return GetByFirst(first); }
}
public TFirst this[TSecond second]
{
get { return GetBySecond(second); }
}
public TSecond GetByFirst(TFirst first)
{
return firstToSecond[first];
}
public TFirst GetBySecond(TSecond second)
{
return secondToFirst[second];
}
public IEnumerator GetEnumerator()
{
return GetFirstEnumerator();
}
public IEnumerator GetFirstEnumerator()
{
return firstToSecond.GetEnumerator();
}
public IEnumerator GetSecondEnumerator()
{
return secondToFirst.GetEnumerator();
}
}
}
And as a consuming class you could have
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace MyApp.Dictionaries
{
class Greek
{
public static readonly string Alpha = "Alpha";
public static readonly string Beta = "Beta";
public static readonly string Gamma = "Gamma";
public static readonly string Delta = "Delta";
private static readonly BiDictionary<int, string> Dictionary = new BiDictionary<int, string>();
static Greek() {
Dictionary.Add(1, Alpha);
Dictionary.Add(2, Beta);
Dictionary.Add(3, Gamma);
Dictionary.Add(4, Delta);
}
public static string getById(int id){
return Dictionary.GetByFirst(id);
}
public static int getByValue(string value)
{
return Dictionary.GetBySecond(value);
}
}
}

You can use chmod with the X
mode letter (the capital X) to set the executable flag only for directories.
In the example below the executable flag is cleared and then set for all directories recursively:
~$ mkdir foo
~$ mkdir foo/bar
~$ mkdir foo/baz
~$ touch foo/x
~$ touch foo/y
~$ chmod -R go-X foo
~$ ls -l foo
total 8
drwxrw-r-- 2 wq wq 4096 Nov 14 15:31 bar
drwxrw-r-- 2 wq wq 4096 Nov 14 15:31 baz
-rw-rw-r-- 1 wq wq 0 Nov 14 15:31 x
-rw-rw-r-- 1 wq wq 0 Nov 14 15:31 y
~$ chmod -R go+X foo
~$ ls -l foo
total 8
drwxrwxr-x 2 wq wq 4096 Nov 14 15:31 bar
drwxrwxr-x 2 wq wq 4096 Nov 14 15:31 baz
-rw-rw-r-- 1 wq wq 0 Nov 14 15:31 x
-rw-rw-r-- 1 wq wq 0 Nov 14 15:31 y
A bit of explaination:
chmod -x foo
- clear the eXecutable flag for foo
chmod +x foo
- set the eXecutable flag for foo
chmod go+x foo
- same as above, but set the flag only for Group and Other users, don't touch the User (owner) permissionchmod go+X foo
- same as above, but apply only to directories, don't touch fileschmod -R go+X foo
- same as above, but do this Recursively for all subdirectories of foo
I'm more used to the subquery solution to this, but I have not tried it in MySQL:

A scalar always holds a single element. Whatever is in a scalar variable is always a scalar. A reference is a scalar value.
If you want to know if it is a reference, you can use ref
. If you want to know the reference type,
you can use the reftype
routine from Scalar::Util.
If you want to know if it is an object, you can use the blessed
routine from Scalar::Util. You should never care what the blessed package is, though. UNIVERSAL
has some methods to tell you about an object: if you want to check that it has the method you want to call, use can
; if you want to see that it inherits from something, use isa
; and if you want to see it the object handles a role, use DOES
.
If you want to know if that scalar is actually just acting like a scalar but tied to a class, try tied
. If you get an object, continue your checks.
If you want to know if it looks like a number, you can use looks_like_number
from Scalar::Util. If it doesn't look like a number and it's not a reference, it's a string. However, all simple values can be strings.
If you need to do something more fancy, you can use a module such as Params::Validate.
You should pass length into fwrite instead of sizeof(buffer).
You can only return one value, but it can be an object that has multiple fields - ie a "value object". Eg
public class MyResult {
int returnCode;
String errorMessage;
// etc
}
public MyResult someMethod() {
// impl here
}
csvde -f test.csv
This command will perform a CSV dump of every entry in your Active Directory server. You should be able to see the full DN's of users and groups.
You will have to go through that output file and get rid off the unnecessary content.
gcc
can use an assembly file as input, and invoke the assembler as needed. There is a subtlety, though:
.s
" (lowercase 's'), then gcc
calls the assembler..S
" (uppercase 'S'), then gcc
applies the C preprocessor on the source file (i.e. it recognizes directives such as #if
and replaces macros), and then calls the assembler on the result.So, on a general basis, you want to do things like this:
gcc -S file.c -o file.s
gcc -c file.s
This might be a late response but in order to avoid using a loop you can also call the method recursively. It looks and feels slightly cleaner to me.
class ModelName < ActiveRecord::Base
before_create :generate_token

self.token = SecureRandom.urlsafe_base64

@RobinL as mentioned in previous comments, you can use chart.series[n].setData(). First you need to make sure you’ve assigned a chart instance to the chart variable, that way it adopts all the properties and methods you need to access and manipulate the chart.
I’ve also used the second parameter of setData() and had it false, to prevent automatic rendering of the chart. This was because I have multiple data series, so I’ll rather update each of them, with render=false, and then running chart.redraw(). This multiplied performance (I’m having 10,000-100,000 data points and refreshing the data set every 50 milliseconds).
I just used the @misir-jafarov and is working now with :
here is my code :
if (document.documentMode || /Edge/.test(navigator.userAgent)) {
jQuery('.art-img img').each(function(){
var t = jQuery(this),
s = 'url(' + t.attr('src') + ')',
p = t.parent(),
d = jQuery('<div></div>');
p.append(d);
d.css({
'height' : t.parent().css('height'),
'background-size' : 'cover',
'background-repeat' : 'no-repeat',
'background-position' : '50% 20%',
'background-image' : s
});
t.hide();
});
}
Hope it helps.
FragmentActivity
gives you all of the functionality of Activity
plus the ability to use Fragments which are very useful in many cases, particularly when working with the ActionBar, which is the best way to use Tabs in Android.
If you are only targeting Honeycomb (v11) or greater devices, then you can use Activity
and use the native Fragments introduced in v11 without issue. FragmentActivity
was built specifically as part of the Support Library to back port some of those useful features (such as Fragments) back to older devices.
I should also note that you'll probably find the Backward Compatibility - Implementing Tabs training very helpful going forward.
Another way to get the user name (and most of the information) is to access the database directly and read the info from the tables.
http://joda-time.sourceforge.net/quickstart.html
Each datetime class provides a variety of constructors. These include the Object constructor. This allows you to construct, for example, DateTime from the following objects:
* Date - a JDK instant
* Calendar - a JDK calendar
* String - in ISO8601 format
* Long - in milliseconds
* any Joda-Time datetime class
If you want to return from an outer function with an error without exit
ing you can use this trick:
do-something-complex() {
# Using `return` here would only return from `fail`, not from `do-something-complex`.
# Using `exit` would close the entire shell.
# So we (ab)use a different feature. :)
fail() { : "${__fail_fast:?$1}"; }
nested-func() {
try-this || fail "This didn't work"
try-that || fail "That didn't work"
}
nested-func
}
Trying it out:
$ do-something-complex
try-this: command not found
bash: __fail_fast: This didn't work
This has the added benefit/drawback that you can optionally turn off this feature: __fail_fast=x do-something-complex
.
Note that this causes the outermost function to return 1.
An important tip if the string that is being chunked needs to support all Unicode characters.
If the string is to support international characters like , then split up the string using the System.Globalization.StringInfo class. Using StringInfo, you can split up the string based on number of text elements.
string internationalString = '';
The above string has a Length of 2, because the String.Length
property returns the number of Char objects in this instance, not the number of Unicode characters.

Here is how you can easily remove the $$hashKey from the object:
$scope.myNewObject = JSON.parse(angular.toJson($scope.myObject))
$scope.myObject
- Refers to the Object that you want to perform the operation upon i.e. remove the $$hashKey from
$scope.myNewObject
- Assign the modified original object to the new object so it can be used as necessary

What I usually do when I get this error is restarting the adb
server by typing in the cmd:
adb kill-server
adb start-server
EDIT: With some never versions of the Platform Tools you can do this from the DDMS Perspective
in the Devices Tab
menu (near the Capture Button), click on Reset adb
.
EDIT2: Also I found out that it is preferable to use the USB port
in the back of your PC, since most of the front USB ports
are low powered, and really seem to be slower when uploading apks
on your devices.
While macros and/or functions (as already suggested) will work (and might have other positive effects (i.e. debug hooks)), they are more complex than needed. The simplest and possibly most elegant solution is to just define a constant that you use for variable initialisation:
const struct foo FOO_DONT_CARE = { // or maybe FOO_DEFAULT or something
dont_care, dont_care, dont_care, dont_care
};
...
struct foo bar = FOO_DONT_CARE;
bar.id = 42;
bar.current_route = new_route;
update(&bar);
This code has virtually no mental overhead of understanding the indirection, and it is very clear which fields in bar
you set explicitly while (safely) ignoring those you do not set.
For selecting number of lines:
shift+v 9j - select 10 lines
You can try something like this:

{
:id => self.id,
:credit_period_type => self.credit_period_type,
:credit_payment_period => self.credit_payment_period,
}.to_json
end
You need to use the OutputStreamWriter
class as the writer parameter for your BufferedWriter
. It does accept an encoding. Review javadocs for it.
Somewhat like this:
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(
new FileOutputStream("jedis.txt"), "UTF-8"
));
Or you can set the current system encoding with the system property file.encoding
to UTF-8.
java -Dfile.encoding=UTF-8 com.jediacademy.Runner arg1 arg2 ...
You may also set it as a system property at runtime with System.setProperty(...)
if you only need it for this specific file, but in a case like this I think I would prefer the OutputStreamWriter
.
By setting the system property you can use FileWriter
and expect that it will use UTF-8 as the default encoding for your files. In this case for all the files that you read and write.
EDIT
Starting from API 19, you can replace the String "UTF-8" with StandardCharsets.UTF_8
As suggested in the comments below by tchrist, if you intend to detect encoding errors in your file you would be forced to use the OutputStreamWriter
approach and use the constructor that receives a charset encoder.
Somewhat like
CharsetEncoder encoder = Charset.forName("UTF-8").newEncoder();
encoder.onMalformedInput(CodingErrorAction.REPORT);
encoder.onUnmappableCharacter(CodingErrorAction.REPORT);
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("jedis.txt"),encoder));
You may choose between actions IGNORE | REPLACE | REPORT
Also, this question was already answered here.
Note : Use it if calculating / adding days from current date.
Be aware: this answer has issues (see comments)
var myDate = new Date();
myDate.setDate(myDate.getDate() + AddDaysHere);
It should be like
var newDate = new Date(date.setTime( date.getTime() + days * 86400000 ));
It's now called rounded-circle

You use an insert trigger - inside the trigger, inserted row items will be exposed as a logical table INSERTED

Delete triggers have access to a similar logical table called DELETED

Update triggers have access to both an INSERTED
table that contains the updated values and a DELETED

to get the JSON in a string format.
EDIT: If your intention is to get the id and other properties from the result object and you want to see it console to know if its there then you can check with hasOwnProperty
and access the property if it does exist:
var obj = {id : "007", name : "James Bond"};
console.log(obj); // Object { id: "007", name: "James Bond" }
console.log(JSON.stringify(obj)); //{"id":"007","name":"James Bond"}
if (obj.hasOwnProperty("id")){
console.log(obj.id); //007

onMeasure()
is your opportunity to tell Android how big you want your custom view to be dependent the layout constraints provided by the parent; it is also your custom view's opportunity to learn what those layout constraints are (in case you want to behave differently in a match_parent
situation than a wrap_content
situation). These constraints are packaged up into the MeasureSpec
values that are passed into the method. Here is a rough correlation of the mode values:
layout_width
or layout_height
value was set to a specific value. You should probably make your view this size. This can also get triggered when match_parent
is used, to set the size exactly to the parent view (this is layout dependent in the framework).layout_width
or layout_height
value was set to match_parent
or wrap_content
where a maximum size is needed (this is layout dependent in the framework), and the size of the parent dimension is the value. You should not be any larger than this size.layout_width
or layout_height
value was set to wrap_content
with no restrictions. You can be whatever size you would like. Some layouts also use this callback to figure out your desired size before determine what specs to actually pass you again in a second measure request.The contract that exists with onMeasure()
is that setMeasuredDimension()
MUST be called at the end with the size you would like the view to be. This method is called by all the framework implementations, including the default implementation found in View
, which is why it is safe to call super
instead if that fits your use case.
Granted, because the framework does apply a default implementation, it may not be necessary for you to override this method, but you may see clipping in cases where the view space is smaller than your content if you do not, and if you lay out your custom view with wrap_content
in both directions, your view may not show up at all because the framework doesn't know how large it is!
Generally, if you are overriding View
and not another existing widget, it is probably a good idea to provide an implementation, even if it is as simple as something like this:
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int desiredWidth = 100;
int desiredHeight = 100;
int widthMode = MeasureSpec.getMode(widthMeasureSpec);
int widthSize = MeasureSpec.getSize(widthMeasureSpec);
int heightMode = MeasureSpec.getMode(heightMeasureSpec);
int heightSize = MeasureSpec.getSize(heightMeasureSpec);
int width;
int height;
//Measure Width
if (widthMode == MeasureSpec.EXACTLY) {
//Must be this size
width = widthSize;
} else if (widthMode == MeasureSpec.AT_MOST) {
//Can't be bigger than...
width = Math.min(desiredWidth, widthSize);
} else {
//Be whatever you want
width = desiredWidth;
}
//Measure Height
if (heightMode == MeasureSpec.EXACTLY) {
//Must be this size
height = heightSize;
} else if (heightMode == MeasureSpec.AT_MOST) {
//Can't be bigger than...
height = Math.min(desiredHeight, heightSize);
} else {

setMeasuredDimension(width, height);
}
Hope that Helps.
You don't really need to have parenthesis. You can sort directly:
SELECT *, 1 AS RN FROM TABLE_A
UNION ALL
SELECT *, 2 AS RN FROM TABLE_B
ORDER BY RN, COLUMN_1
When doing;
a_file = open('E:\Python Win7-64-AMD 3.3\Test', encoding='utf-8')
...you're trying to open a directory as a file, which may (and on most non UNIX file systems will) fail.
Your other example though;
a_file = open('E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')
should work well if you just have the permission on a.txt
. You may want to use a raw (r
-prefixed) string though, to make sure your path does not contain any escape characters like \n
that will be translated to special characters.
a_file = open(r'E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')
You could also use this snippet:
var app = require("express");
app.get('/', function(req,res){
res.sendFile(__dirname+'./dir/yourfile.html')
});
app.listen(3000);
We use this instruction to obtain users according to two conditions, type of user classification and user name.
Here we use two conditions for filtering as you type in addition to fetching user information from the profiles table to reduce the number of queries.
$users = $this->user->where([
['name','LIKE','%'.$request->name.'%'],
['trainers_id','=',$request->trainers_id]
])->with('profiles')->paginate(10);
There is a way to create war file of your project from eclipse.
First a create an xml file with the following code,
Replace HistoryCheck with your project name.
<?xml version="1.0" encoding="UTF-8"?>
<project name="HistoryCheck" basedir="." default="default">
<target name="default" depends="buildwar,deploy"></target>
<target name="buildwar">
<war basedir="war" destfile="HistoryCheck.war" webxml="war/WEB-INF/web.xml">
<exclude name="WEB-INF/**" />
<webinf dir="war/WEB-INF/">
<include name="**/*.jar" />
</webinf>
</war>
</target>
<target name="deploy">
<copy file="HistoryCheck.war" todir="." />
</target>
</project>
Now, In project explorer right click on that xml file and Run as-> ant build
You can see the war file of your project in your project folder.
Or, similar to erikkallen's idea, make the background of the A tag black, and make the image semitransparent on mouseover. That way you won't have to create additional divs.
Source for the CSS-based solution:
a.darken {
display: inline-block;
background: black;
padding: 0;
}
a.darken img {
display: block;
-webkit-transition: all 0.5s linear;
-moz-transition: all 0.5s linear;
-ms-transition: all 0.5s linear;
-o-transition: all 0.5s linear;
transition: all 0.5s linear;
}
a.darken:hover img {
opacity: 0.7;
}
And the image:

Use /usr/libexec/java_home -v 1.8
command on a terminal shell to figure out where is your Java 1.8 home directory
If you just want to find out the home directory of your most recent version of Java, omit the version. e.g. /usr/libexec/java_home
General rule is that you want packages from require-dev section only in development (dev) environments, for example local environment.
Packages in require-dev section are packages which help you debug app, run tests etc.
At staging and production environment you probably want only packages from require section.
But anyway you can run composer install --no-dev and composer update --no-dev on any environment, command will install only packages from required section not from require-dev, but probably you want to run this only at staging and production environments not on local.
Theoretically you can put all packages in require section and nothing will happened, but you don't want developing packages at production environment because of the following reasons :
Some good candidates for require-dev are :
"filp/whoops": "^2.0",
"fzaninotto/faker": "^1.4",
"mockery/mockery": "^1.0",
"nunomaduro/collision": "^2.0",
"phpunit/phpunit": "^7.0"
you can see what above packages are doing and you will see why you don't need them on production.
See more here : https://getcomposer.org/doc/04-schema.md
data.reshape((50,1104,-1))
works for me
I had similar issue and the below line helped me solving the issue.Thanks to rene. I just pasted this line above the authentication code and it worked
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
You can create an extension method. I find this to be a good practice as you may need to lock down a currency display regardless of the browser setting. For instance you may want to display $5,000.00 always instead of 5 000,00 $ (#CanadaProblems)
public static class DecimalExtensions
{
public static string ToCurrency(this decimal decimalValue)
{
return $"{decimalValue:C}";
}
}
You can only delete with your time field, which is a number.
Delete from <measurement> where time=123456
will work. Remember not to give single quotes or double quotes. Its a number.
In Visual Studio 2019 you can find cl.exe inside
32-BIT : C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.20.27508\bin\Hostx86\x86
64-BIT : C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.20.27508\bin\Hostx64\x64
Before trying to compile either run vcvars32 for 32-Bit compilation or vcvars64 for 64-Bit.
32-BIT : "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars32.bat"
64-BIT : "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat"
If you can't find the file or the directory, try going to C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC
and see if you can find a folder with a version number. If you can't, then you probably haven't installed C++ through the Visual Studio Installation yet.
Here is improved @lucasjones answer. I included improvements mentioned in comment section after his answer. I hope someone will find this useful.
public static string[] GetTypePropertyNames(object classObject, BindingFlags bindingFlags)
{
if (classObject == null)
{
throw new ArgumentNullException(nameof(classObject));
}
var type = classObject.GetType();
var propertyInfos = type.GetProperties(bindingFlags);
return propertyInfos.Select(propertyInfo => propertyInfo.Name).ToArray();
}
int* test();
but it would be "more C++" to use vectors:
std::vector< int > test();
EDIT
I'll clarify some point. Since you mentioned C++, I'll go with new[]
and delete[]
operators, but it's the same with malloc/free.
In the first case, you'll write something like:
int* test() {
return new int[size_needed];
}
but it's not a nice idea because your function's client doesn't really know the size of the array you are returning, although the client can safely deallocate it with a call to delete[]
.
int* theArray = test();
for (size_t i; i < ???; ++i) { // I don't know what is the array size!
// ...
}
delete[] theArray; // ok.
A better signature would be this one:
int* test(size_t& arraySize) {
array_size = 10;
return new int[array_size];
}
And your client code would now be:
size_t theSize = 0;
int* theArray = test(theSize);
for (size_t i; i < theSize; ++i) { // now I can safely iterate the array
// ...
}
delete[] theArray; // still ok.
Since this is C++, std::vector<T>
is a widely-used solution:
std::vector<int> test() {
std::vector<int> vector(10);
return vector;
}
Now you don't have to call delete[]
, since it will be handled by the object, and you can safely iterate it with:
std::vector<int> v = test();
std::vector<int>::iterator it = v.begin();
for (; it != v.end(); ++it) {
// do your things
}
which is easier and safer.
I found this;
from here;
vba- Can a combobox present more then one column on it's textbox part?
and this may help;
I added a sort of demo here;
vec1[i] = vec2[i]
will set the value of vec1[i]
to the value of vec2[i]
. Nothing is inserted. Your second approach is almost correct. Instead of +i+1
you need just +i
v1.insert(v1.begin()+i, v2[i])

Steps I followed
1) Execute the command adb nodaemon server
in command prompt
Output at command prompt will be: The following error occurred cannot bind 'tcp:5037'
The original ADB server port binding failed
2) Enter the following command query which using port 5037
netstat -ano | findstr "5037"
The following information will be prompted on command prompt: TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 9288
3) View the task manager, close all adb.exe
4) Restart eclipse or other IDE
The above steps worked for me.
Looks like you haven't properly installed the header files and static libraries for python dev. Use your package manager to install them system-wide.
For apt
(Ubuntu, Debian...):
sudo apt-get install python-dev # for python2.x installs
sudo apt-get install python3-dev # for python3.x installs

You just need to a add the path of your PHP
file. In case you are using wamp
or have not installed it on the C drive.
is simple for me use base64_encode
$term = base64_encode($term)
$url = $youurl.'?term='.$term
after you decode the term
$term = base64_decode($['GET']['term'])
this way encode the "/" and "\"
private Map<String, Integer> _map= new HashMap<String, Integer>();
Iterator<Map.Entry<String,Integer>> itr= _map.entrySet().iterator();
//please check
while(itr.hasNext())
{
System.out.println("key of : "+itr.next().getKey()+" value of Map"+itr.next().getValue());
}
As of EF 5.0, you need to include the System.ComponentModel.DataAnnotations.Schema
namespace.
Note the potential for an out-of-range index with "i+3". You could do something like:
with open("file.txt", "r") as f:
searchlines = f.readlines()
j=len(searchlines)-1
for i, line in enumerate(searchlines):
if "searchphrase" in line:
k=min(i+3,j)
for l in searchlines[i:k]: print l,
print
Edit: maybe not necessary. I just tested some examples. x[y] will give errors if y is out of range, but x[y:z] doesn't seem to give errors for out of range values of y and z.

Handling key events consistently is not at all easy.
Firstly, there are two different types of codes: keyboard codes (a number representing the key on the keyboard the user pressed) and character codes (a number representing a Unicode character). You can only reliably get character codes in the keypress
event. Do not try to get character codes for keyup
and keydown
events.
Secondly, you get different sets of values in a keypress
event to what you get in a keyup
or keydown
event.
I recommend this page as a useful resource. As a summary:
If you're interested in detecting a user typing a character, use the keypress
event. IE bizarrely only stores the character code in keyCode
while all other browsers store it in which
. Some (but not all) browsers also store it in charCode
and/or keyCode
. An example keypress handler:
function(evt) {
evt = evt || window.event;
var charCode = evt.which || evt.keyCode;
var charStr = String.fromCharCode(charCode);
alert(charStr);
}
If you're interested in detecting a non-printable key (such as a cursor key), use the keydown
event. Here keyCode
is always the property to use. Note that keyup
events have the same properties.
function(evt) {
evt = evt || window.event;
var keyCode = evt.keyCode;
// Check for left arrow key
if (keyCode == 37) {
alert("Left arrow");
}
}
I would be very careful if you are considering adopting this hashbang convention.
Once you hashbang, you can’t go back. This is probably the stickiest issue. Ben’s post put forward the point that when pushState is more widely adopted then we can leave hashbangs behind and return to traditional URLs. Well, fact is, you can’t. Earlier I stated that URLs are forever, they get indexed and archived and generally kept around. To add to that, cool URLs don’t change. We don’t want to disconnect ourselves from all the valuable links to our content. If you’ve implemented hashbang URLs at any point then want to change them without breaking links the only way you can do it is by running some JavaScript on the root document of your domain. Forever. It’s in no way temporary, you are stuck with it.
You really want to use pushState instead of hashbangs, because making your URLs ugly and possibly broken -- forever -- is a colossal and permanent downside to hashbangs.
you can add this code to web.config in asp mvc
<system.webServer>
<staticContent>
<remove fileExtension=".srt" />
<mimeMap fileExtension=".srt" mimeType="text/srt" />
<remove fileExtension=".vtt" />
<mimeMap fileExtension=".vtt" mimeType="text/vtt" />

I've encountered the same issue while following the React Native tutorial (developing on Linux and targeting Android).
This issue helped me resolve the problem in following steps. Run following commands in the below sequence:
mkdir android/app/src/main/assets
react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
react-native run-android
You can automate the above steps by placing them in scripts
part of package.json
like this:
"android-linux": "react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res && react-native run-android"
Then you can just execute npm run android-linux
from your command line every time.
extension UIView {
func installShadow() {
layer.cornerRadius = 2
layer.masksToBounds = false
layer.shadowColor = UIColor.black.cgColor
layer.shadowOffset = CGSize(width: 0, height: 1)
layer.shadowOpacity = 0.45
layer.shadowPath = UIBezierPath(rect: bounds).cgPath
layer.shadowRadius = 1.0
}
}
$(".oSlider-rotate").slider({
min: 10,
max: 74,
step: .01,
value: 24,
slide: function(e,ui){
$('.user-text').css('transform', 'scale(' + ui.value + ')')
}
});
This will solve the issue
Using the following ways using only two keys will be the easier:
control + Tab
or
Alt + Left/Right
Use the command dir
to list all the directories and files in a directory; ls
is a unix command.
You are not able to return 'multiple values' in PHP. You can return a single value, which might be an array.
function foo($test1, $test2, $test3)
{
return array($test1, $test2, $test3);
}
$test1 = "1";
$test2 = "2";
$test3 = "3";
$arr = foo($test1, $test2, $test3);
$test1 = $arr[0];
$test2 = $arr[1];
$test3 = $arr[2];
See it in Activity Lifecycle (at Android Developers).
Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().
Called after your activity has been stopped, prior to it being started again. Always followed by onStart()
Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground.
Called when the activity will start interacting with the user. At this point your activity is at the top of the activity stack, with user input going to it. Always followed by onPause().
Called as part of the activity lifecycle when an activity is going into the background, but has not (yet) been killed. The counterpart to onResume(). When activity B is launched in front of activity A, this callback will be invoked on A. B will not be created until A's onPause() returns, so be sure to not do anything lengthy here.
Called when you are no longer visible to the user. You will next receive either onRestart(), onDestroy(), or nothing, depending on later user activity. Note that this method may never be called, in low memory situations where the system does not have enough memory to keep your activity's process running after its onPause() method is called.
The final call you receive before your activity is destroyed. This can happen either because the activity is finishing (someone called finish() on it, or because the system is temporarily destroying this instance of the activity to save space. You can distinguish between> these two scenarios with the isFinishing() method.
When the Activity first time loads the events are called as below:
onCreate()
onStart()
onResume()
When you click on Phone button the Activity goes to the background and the below events are called:
onPause()
onStop()
Exit the phone dialer and the below events will be called:
onRestart()
onStart()
onResume()
When you click the back button OR try to finish() the activity the events are called as below:
onPause()
onStop()
onDestroy()
The Android OS uses a priority queue to assist in managing activities running on the device. Based on the state a particular Android activity is in, it will be assigned a certain priority within the OS. This priority system helps Android identify activities that are no longer in use, allowing the OS to reclaim memory and resources. The following diagram illustrates the states an activity can go through, during its lifetime:
These states can be broken into three main groups as follows:
Active or Running - Activities are considered active or running if they are in the foreground, also known as the top of the activity stack. This is considered the highest priority activity in the Android Activity stack, and as such will only be killed by the OS in extreme situations, such as if the activity tries to use more memory than is available on the device as this could cause the UI to become unresponsive.
Paused - When the device goes to sleep, or an activity is still visible but partially hidden by a new, non-full-sized or transparent activity, the activity is considered paused. Paused activities are still alive, that is, they maintain all state and member information, and remain attached to the window manager. This is considered to be the second highest priority activity in the Android Activity stack and, as such, will only be killed by the OS if killing this activity will satisfy the resource requirements needed to keep the Active/Running Activity stable and responsive.
Stopped - Activities that are completely obscured by another activity are considered stopped or in the background. Stopped activities still try to retain their state and member information for as long as possible, but stopped activities are considered to be the lowest priority of the three states and, as such, the OS will kill activities in this state first to satisfy the resource requirements of higher priority activities.
*Sample activity to understand the life cycle**
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class MainActivity extends Activity {
String tag = "LifeCycleEvents";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.d(tag, "In the onCreate() event");
}
public void onStart()
{
super.onStart();
Log.d(tag, "In the onStart() event");
}
public void onRestart()
{
super.onRestart();
Log.d(tag, "In the onRestart() event");
}
public void onResume()
{
super.onResume();
Log.d(tag, "In the onResume() event");
}
public void onPause()
{
super.onPause();
Log.d(tag, "In the onPause() event");
}
public void onStop()
{
super.onStop();
Log.d(tag, "In the onStop() event");
}
public void onDestroy()
{
super.onDestroy();
Log.d(tag, "In the onDestroy() event");
}
}
I also had added on or extended additional columns into my AspNetUsers table. When I wanted to simply view this data I found many examples like the code above with "Extensions" etc... This really amazed me that you had to write all those lines of code just to get a couple values from the current users.
It turns out that you can query the AspNetUsers table like any other table:
ApplicationDbContext db = new ApplicationDbContext();
var user = db.Users.Where(x => x.UserName == User.Identity.Name).FirstOrDefault();
If you like python and have an option to install a package, you can use this utility that I made.
# install pythonp
python -m pip install pythonp
pythonp "5*5"
25
pythonp "1 / (1+math.exp(0.5))"
0.3775406687981454
# define a custom function and pass it to another higher-order function
pythonp "n=10;functools.reduce(lambda x,y:x*y, range(1,n+1))"

I was missing a React Fragment:
function Bar({ children }) {
return (
<div>
{children}
</div>
);
}
function Foo() {
return (
<Bar>
<Baz/>
<Qux/>
</Bar>
);
}
The code above throws the error above. But this fixes it:
<Bar>
<>
<Baz/>
<Qux/>
</>
</Bar>
This should do what you're looking for:
function clean($string) {
$string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens.
return preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars.
}
Usage:
echo clean('a|"bc!@£de^&$f g');
Will output: abcdef-g
Edit:
Hey, just a quick question, how can I prevent multiple hyphens from being next to each other? and have them replaced with just 1?
function clean($string) {
$string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens.
$string = preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars.
return preg_replace('/-+/', '-', $string); // Replaces multiple hyphens with single one.
}
Depending on which tool windows you have open, VS may or may not try to hit the team server automatically when it starts up.
For best results try this:
You should notice now that you can start visual studio without it trying to hit the TFS server.
I know its just an aside to your problem, but I hope you find this helpful!
You can use in
to look for an item in a collection, and a list comprehension to extract the field you are interested in. This (works for lists, sets, tuples, and anything that defines __contains__
or __getitem__
).
if 5 in [data.n for data in myList]:
print "Found it"

What might be easier, is to have two buttons and show/hide them in your functions. (ie. display:none|block;
) Each button could then have it's own onclick with whatever code you need.
So, at first button1
would be display:block
and button2
would be display:none
. Then when you click button1
it would switch button2
to be display:block
and button1
to be display:none
.
Here is pythonic way to do it. This function will allow you to loop through key-value pair in all the levels. It does not save the whole thing to the memory but rather walks through the dict as you loop through it
def recursive_items(dictionary):
for key, value in dictionary.items():

This is the only "simple" way to do this in SQL Server without some giant convoluted created function or executed sql string call, both of which are terrible solutions:
EXAMPLE:
INSERT INTO #YOUR_TEMP_TABLE
SELECT * FROM OPENROWSET ('SQLOLEDB','Server=(local);TRUSTED_CONNECTION=YES;','set fmtonly off EXEC [ServerName].dbo.[StoredProcedureName] 1,2,3')
Note: You MUST use 'set fmtonly off', AND you CANNOT add dynamic sql to this either inside the openrowset call, either for the string containing your stored procedure parameters or for the table name. Thats why you have to use a temp table rather than table variables, which would have been better, as it out performs temp table in most cases.
Same as the updating existing collection field, $set
will add a new fields if the specified field does not exist.
Check out this example:
> db.foo.find()
> db.foo.insert({"test":"a"})
> db.foo.find()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "test" : "a" }
> item = db.foo.findOne()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "test" : "a" }
> db.foo.update({"_id" :ObjectId("4e93037bbf6f1dd3a0a9541a") },{$set : {"new_field":1}})
> db.foo.find()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "new_field" : 1, "test" : "a" }
EDIT:
In case you want to add a new_field to all your collection, you have to use empty selector, and set multi flag to true (last param) to update all the documents
db.your_collection.update(
{},
{ $set: {"new_field": 1} },
false,
true
)
EDIT:
In the above example last 2 fields false, true
specifies the upsert
and multi
flags.
Upsert: If set to true, creates a new document when no document matches the query criteria.
Multi: If set to true, updates multiple documents that meet the query criteria. If set to false, updates one document.
This is for Mongo versions
prior to 2.2
. For latest versions the query is changed a bit
db.your_collection.update({},
{$set : {"new_field":1}},
{upsert:false,
multi:true})
One line working answer:
$url = "http://www.yoursite/one/two/three/drink";
echo $end = end((explode('/', $url)));
Output: drink
I can relate to the problem, there should be a shorthand like...
border: 1px solid red top bottom left;
Of course that doesn't work! Kobi's answer gave me an idea. Let's say you want to do top, bottom and left, but not right. Instead of doing border-top: border-left: border-bottom: (three statements) you could do two like this, the zero cancels out the right side.
border: 1px dashed yellow;
border-width:1px 0 1px 1px;
Two statements instead of three, small improvement :-D
Note: if you want to disable ARC for many files, you have to:
-fno-objc-arc
I can' t comment yet but, just a hint: use try/catch clauses to avoid breaking the pipeline (if you are sure the file exists, disregard)
pipeline {
agent any
stages {
stage("foo") {
steps {
script {
try {
env.FILENAME = readFile 'output.txt'
echo "${env.FILENAME}"
}
catch(Exception e) {
//do something, e.g. echo 'File not found'
}
}
}
}
Another hint (this was commented by @hao, and think is worth to share): you may want to trim like this readFile('output.txt').trim()
Hi try this,
var callback_function = new Function(functionName);
callback_function();
it will handle the parameters itself.
Change the Foreign key name in MySQL. You can not have the same foreign key names in the database tables.
Check all your tables and all your foreign keys and avoid having two foreign keys with the same exact name.
Also you can pipe the answers to the script:
printf "y\npassword\n" | sh test.sh
where \n
is escape-sequence
For each iteration of the ng-repeat loop, line
is a reference to an object in your array. Therefore, to preview the value, use {{line.text}}
.
Similarly, to databind to the text, databind to the same: ng-model="line.text"
. You don't need to use value
when using ng-model (actually you shouldn't).
For a more in-depth look at scopes and ng-repeat, see What are the nuances of scope prototypal / prototypical inheritance in AngularJS?, section ng-repeat.

In Symfony 2.6 and older versions, to get a parameter in a controller - you should get the container first, and then - the needed parameter.
$this->container->getParameter('api_user');
This documentation chapter explains it.
While $this->get()
method in a controller will load a service (doc)
In Symfony 2.7 and newer versions, to get a parameter in a controller you can use the following:
$this->getParameter('api_user');
It means the data type is derived (implied) from the context.
From http://msdn.microsoft.com/en-us/library/bb383973.aspx
Beginning in Visual C# 3.0, variables that are declared at method scope can have an implicit type var. An implicitly typed local variable is strongly typed just as if you had declared the type yourself, but the compiler determines the type. The following two declarations of i are functionally equivalent:
var i = 10; // implicitly typed
int i = 10; //explicitly typed
var
is useful for eliminating keyboard typing and visual noise, e.g.,
MyReallyReallyLongClassName x = new MyReallyReallyLongClassName();
becomes
var x = new MyReallyReallyLongClassName();
but can be overused to the point where readability is sacrificed.
If you're just using it for grep, you can use grep -v hede
to get all lines which do not contain hede.
ETA Oh, rereading the question, grep -v
is probably what you meant by "tools options".
I would add, and also to answer the question find mean bin values using histogram2d python that the scipy also have a function specially designed to compute a bidimensional binned statistic for one or more sets of data
import numpy as np
from scipy.stats import binned_statistic_2d
x = np.random.rand(100)
y = np.random.rand(100)
values = np.random.rand(100)
bin_means = binned_statistic_2d(x, y, values, bins=10).statistic
the function scipy.stats.binned_statistic_dd is a generalization of this funcion for higher dimensions datasets
If you need to disable button add this line of code.
Button button = findViewById(R.id.button)
button.setEnabled(false);
And enable button , just add this line
button.setEnabled(true);
Happy coding :D
You can use the old <xmp>

The simplest supported solution is to either use margin
.element {
display: block;
margin: 0px auto;
}
Or use a second container around the element that has this margin applied. This will somewhat have the effect of padding: 0px auto
if it did exist.
CSS
.element_wrapper {
display: block;
margin: 0px auto;
}
.element {
background: blue;
}
HTML
<div class="element_wrapper">
<div class="element">
Hello world
</div>

check out lxml2json (disclosure: I wrote it)
https://github.com/rparelius/lxml2json
it's very fast, lightweight (only requires lxml), and one advantage is that you have control over whether certain elements are converted to lists or dicts

mysqli_error()
As in:
$sql = "Your SQL statement here";
$result = mysqli_query($conn, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($conn), E_USER_ERROR);
Trigger error is better than die because you can use it for development AND production, it's the permanent solution.
Just add this to your AndroidManifest.xml
<activity android:screenOrientation="landscape">
I mean, there is an activity tag, add this as another parameter. In case if you need portrait orientation, change landscape to portrait. Hope this helps.
I had this problem because I was trying to set up a multiplatform library configurations.
I had deleted all the source sets with their dependencies from the "build.gradle" file but kept the "common" source set.
Native was working fine but the JVM was not able to build and showed your error.
In the end, the solution was to not delete the Source set of the JVM neither it's dependencies
A more duck-typing approach would be to say
foo.respond_to?(:to_str)
to_str
indicates that an object's class may not be an actual descendant of the String, but the object itself is very much string-like (stringy?).
If you want to plot lines instead of points, see this example, modified here to plot good/bad points representing a function as a black/red as appropriate:
def plot(xx, yy, good):
"""Plot data
Good parts are plotted as black, bad parts as red.
Parameters
----------
xx, yy : 1D arrays
Data to plot.
good : `numpy.ndarray`, boolean
Boolean array indicating if point is good.

string.Join
is better, but if you really want a LINQ ForEach
:
var strgroupids = string.Empty;
groupIds.ForEach(g =>
{
if(strgroupids != string.Empty){
strgroupids += ",";
}
strgroupids += g;
});
Some notes:
string.Join
and foreach
are both better than this, vastly slower, approach,
since it's never appended+=
) is handy for appending to strings.ToString()
is unnecessary as it is called automatically when concatenating non-stringsStringBuilder
should be considered instead of concatenating stringsLate but just as a note;
It's possible to add a trivial element to target element as a container and remove it after using.
// Tested on chrome 23.0, firefox 18.0, ie 7-8-9 and opera 12.11.
<div id="div"></div>
<script>
window.onload = function() {
var foo, targetElement = document.getElementById('div')
foo = document.createElement('foo')
foo.innerHTML = '<a href="#" target="_self">Text of A 1.</a> '+
'<a href="#" onclick="return !!alert(this.innerHTML)">Text of <b>A 2</b>.</a> '+
'<hr size="1" />'
// Append 'foo' element to target element
targetElement.appendChild(foo)
// Add event
foo.firstChild.onclick = function() { return !!alert(this.target) }
while (foo.firstChild) {
// Also removes child nodes from 'foo'
targetElement.insertBefore(foo.firstChild, foo)
}
// Remove 'foo' element from target element
targetElement.removeChild(foo)
}
</script>
I've had this problem myself and I've found the great wikipedia page on the subject (in "Common rotations" paragraph:
https://en.wikipedia.org/wiki/Rotation_matrix#Ambiguities
Then I wrote the following code, super verbose in order to have a clear understanding of what is going on.
I hope that you'll find it useful to dig more in the very beautiful and clever one-liner you've posted.
To quickly test it you can copy / paste it here:
http://www.codeskulptor.org/
triangle = [[0,0],[5,0],[5,2]]
coordinates_a = triangle[0]
coordinates_b = triangle[1]
coordinates_c = triangle[2]
def rotate90ccw(coordinates):
print "Start coordinates:"
print coordinates
old_x = coordinates[0]
old_y = coordinates[1]
# Here we apply the matrix coming from Wikipedia
# for 90 ccw it looks like:
# 0,-1
# 1,0
# What does this mean?
#
# Basically this is how the calculation of the new_x and new_y is happening:
# new_x = (0)(old_x)+(-1)(old_y)
# new_y = (1)(old_x)+(0)(old_y)
#
# If you check the lonely numbers between parenthesis the Wikipedia matrix's numbers
# finally start making sense.
# All the rest is standard formula, the same behaviour will apply to other rotations, just
# remember to use the other rotation matrix values available on Wiki for 180ccw and 170ccw
new_x = -old_y
new_y = old_x

An alternative would to use the jdbc.drivers System property to specify your required drivers(s) on the command line when you start the JVM.
@echo off
echo Type your text here.
:top
set /p boompanes=
pause
echo %boompanes%> practice.txt
hope this helps. you should change the string names(IDK what its called) and the file name
That should work:
>>> df = pd.DataFrame()
>>> data = pd.DataFrame({"A": range(3)})
>>> df.append(data)
A
0 0
1 1
2 2
But the append
doesn't happen in-place, so you'll have to store the output if you want it:
>>> df
Empty DataFrame
Columns: []
Index: []
>>> df = df.append(data)
>>> df
A
0 0
1 1
2 2

get_term_meta($value->term_id, 'thumbnail_id', true)

Using the backtick (`) works fine for me if I put them in the following places:
$cmd="\\server\toto.exe -batch=B -param=`"sort1;parmtxt='Security ID=1234'`""
$cmd
returns as:
\\server\toto.exe -batch=B -param="sort1;parmtxt='Security ID=1234'"
Is that what you were looking for?
The error PowerShell gave me referred to an unexpected token 'sort1', and that's how I determined where to put the backticks.
The @' ... '@ syntax is called a "here string" and will return exactly what is entered. You can also use them to populate variables in the following fashion:
$cmd=@'
"\\server\toto.exe -batch=B -param="sort1;parmtxt='Security ID=1234'""
'@
The opening and closing symbols must be on their own line as shown above.
You can use margin. See the example:
li{
margin: 10px 0;
}
If you are looking to highlight a shell session command sequence as it looks to the user (with prompts, not just as contents of a hypothetical script file), then the right identifier to use at the moment is console:
```console
foo@bar:~$ whoami
foo
```
For input you must have used value
to grab its text but for td, you should use innerHTML
to get its html/value. Example:
alert(document.getElementById("td_id_here").innerHTML);
To get its text though, use:
alert(document.getElementById("td_id_here").innerText);

let stringValue = "How to\ncontrol\nthe\nline spacing\nin UILabel"
// Pass value for any one argument - lineSpacing or lineHeightMultiple
label.setLineSpacing(lineSpacing: 2.0) . // try values 1.0 to 5.0

let label = UILabel()
let stringValue = "Set\nUILabel\nline\nspacing"
let attrString = NSMutableAttributedString(string: stringValue)
var style = NSMutableParagraphStyle()
style.lineSpacing = 24 // change line spacing between paragraph like 36 or 48
style.minimumLineHeight = 20 // change line spacing between each line like 30 or 40
// Line spacing attribute
attrString.addAttribute(NSAttributedStringKey.paragraphStyle, value: style, range: NSRange(location: 0, length: stringValue.characters.count))
// Character spacing attribute
attrString.addAttribute(NSAttributedStringKey.kern, value: 2, range: NSMakeRange(0, attrString.length))
label.attributedText = attrString
Swift 3
let label = UILabel()

After looking on the accepted answer I realized that if know size of required vector then we have to use a loop to initialize every element
But I found new to do this using default_structure_element like following...
#include <bits/stdc++.h>
typedef long long ll;
using namespace std;
typedef struct subject {
string name;
int marks;
int credits;
}subject;
int main(){
subject default_subject;
default_subject.name="NONE";
default_subject.marks = 0;
default_subject.credits = 0;
vector <subject> sub(10,default_subject); // default_subject to initialize
//to check is it initialised
for(ll i=0;i<sub.size();i++) {
cout << sub[i].name << " " << sub[i].marks << " " << sub[i].credits << endl;
}
}
Then I think its good to way to initialize a vector of the struct, isn't it?
Try using qx{command}
rather than backticks. To me, it's a bit better because: you can do SQL with it and not worry about escaping quotes and such. Depending on the editor and screen, my old eyes tend to miss the tiny back ticks, and it shouldn't ever have an issue with being overloaded like using angle brackets versus glob.
If you don't want to use API 21 you can use the older version of appcompact library, use older app compact library without updating it.
you can achieve this by simply following steps:
1) Extract the downloaded version of complete sdk and eclipse bundle.
2) Simply import appCompact library from sdk\extras\android\support\v7\appcompact
now you are done.
