#pragma
is used to do something implementation-specific in C, i.e. be pragmatic for the current context rather than ideologically dogmatic.
The one I regularly use is #pragma pack(1)
where I'm trying to squeeze more out of my memory space on embedded solutions, with arrays of structures that would otherwise end up with 8 byte alignment.
Pity we don't have a #dogma
yet. That would be fun ;)
You need to know the chunk size by which you're dividing your list. Say you have a list of 108 entries
and you need a chunk size of 25
. Thus you will end up with 5 lists
:
25 entries
each;8 elements
. Code:
public static void main(String[] args) {
List<Integer> list = new ArrayList<Integer>();
for (int i=0; i<108; i++){
list.add(i);
}
int size= list.size();
int j=0;
List< List<Integer> > splittedList = new ArrayList<List<Integer>>() ;
List<Integer> tempList = new ArrayList<Integer>();
for(j=0;j<size;j++){
tempList.add(list.get(j));
if((j+1)%25==0){
// chunk of 25 created and clearing tempList
splittedList.add(tempList);
tempList = null;
//intializing it again for new chunk
tempList = new ArrayList<Integer>();
}
}
if(size%25!=0){
//adding the remaining enteries
splittedList.add(tempList);
}
for (int k=0;k<splittedList.size(); k++){
//(k+1) because we started from k=0
System.out.println("Chunk number: "+(k+1)+" has elements = "+splittedList.get(k).size());
}
}
Another way to totally override the cart.php is to copy:
woocommerce/templates/cart/cart.php to
yourtheme/woocommerce/cart/cart.php
Then do whatever you need at the yourtheme/woocommerce/cart/cart.php
Use Instant
, replacement for java.util.Date
.
Instant.now() // Capture current moment as seen in UTC.
If you must have a Date
, convert.
java.util.Date.from( Instant.now() )
The java.util.Date & .Calendar classes have been supplanted by the java.time framework built into Java 8 and later. The new classes are a tremendous improvement, inspired by the successful Joda-Time library.
The java.time classes tend to use static factory methods rather than constructors for instantiating objects.
To get the current moment in UTC time zone:
Instant instant = Instant.now();
To get the current moment in a particular time zone:
ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.now( zoneId );
If you must have a java.util.Date for use with other classes not yet updated for the java.time types, convert from Instant
.
java.util.Date date = java.util.Date.from( zdt.toInstant() );
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
For a dynamic approach, if your labels are always in front of your text areas:
$(object).prev("label").text(charsleft);
requireUncached
with relative path:
const requireUncached = require => module => {
delete require.cache[require.resolve(module)];
return require(module);
};
module.exports = requireUncached;
invoke requireUncached with relative path:
const requireUncached = require('../helpers/require_uncached')(require);
const myModule = requireUncached('./myModule');
I just want to add some more information to what @Robert Paulson answered.
Let's assume that node contains key & data. So nodes with the same key might contain different data.
(So the search must find all nodes with the same key)
- left <= cur < right
- left < cur <= right
- left <= cur <= right
- left < cur < right && cur contain sibling nodes with the same key.
- left < cur < right, such that no duplicate keys exist.
1 & 2. works fine if the tree does not have any rotation-related functions to prevent skewness.
But this form doesn't work with AVL tree or Red-Black tree, because rotation will break the principal.
And even if search() finds the node with the key, it must traverse down to the leaf node for the nodes with duplicate key.
Making time complexity for search = theta(logN)
3. will work well with any form of BST with rotation-related functions.
But the search will take O(n), ruining the purpose of using BST.
Say we have the tree as below, with 3) principal.
12
/ \
10 20
/ \ /
9 11 12
/ \
10 12
If we do search(12) on this tree, even tho we found 12 at the root, we must keep search both left & right child to seek for the duplicate key.
This takes O(n) time as I've told.
4. is my personal favorite. Let's say sibling means the node with the same key.
We can change above tree into below.
12 - 12 - 12
/ \
10 - 10 20
/ \
9 11
Now any search will take O(logN) because we don't have to traverse children for the duplicate key.
And this principal also works well with AVL or RB tree.

If you are looking for a handy way to test the equality of two collections, you can use org.apache.commons.collections.CollectionUtils.isEqualCollection
, which compares two collections regardless of the ordering.
Before clear space (trim)
Then replace with RegEx .replace("/\xEF\xBB\xBF/", "")
I'm working on Javascript, I did with JavaScript.
Use command:
ng config schematics.@schematics/angular:component.styleext scss
The easiest way i always handle this Where
$con = mysqli_connect($serverName,$dbusername,$dbpassword);
3 steps replacement in the following order
This works for me everytime
Here is an example
private void doOpenFile() {
int result = myFileChooser.showOpenDialog(this);
if (result == JFileChooser.APPROVE_OPTION) {
Path path = myFileChooser.getSelectedFile().toPath();
try {
String contentString = "";
for (String s : Files.readAllLines(path, StandardCharsets.UTF_8)) {
contentString += s;
}
jText.setText(contentString);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
private void doSaveFile() {
int result = myFileChooser.showSaveDialog(this);
if (result == JFileChooser.APPROVE_OPTION) {
// We'll be making a mytmp.txt file, write in there, then move it to
// the selected
// file. This takes care of clearing that file, should there be
// content in it.
File targetFile = myFileChooser.getSelectedFile();
try {
if (!targetFile.exists()) {
targetFile.createNewFile();
}
FileWriter fw = new FileWriter(targetFile);
fw.write(jText.getText());
fw.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Update for Swift 3.0 and higher
let actionSheetController: UIAlertController = UIAlertController(title: "SomeTitle", message: nil, preferredStyle: .actionSheet)
let editAction: UIAlertAction = UIAlertAction(title: "Edit Details", style: .default) { action -> Void in
print("Edit Details")
}
let deleteAction: UIAlertAction = UIAlertAction(title: "Delete Item", style: .default) { action -> Void in
print("Delete Item")
}
let cancelAction: UIAlertAction = UIAlertAction(title: "Cancel", style: .cancel) { action -> Void in }
actionSheetController.addAction(editAction)
actionSheetController.addAction(deleteAction)
actionSheetController.addAction(cancelAction)
// present(actionSheetController, animated: true, completion: nil) // doesn't work for iPad
actionSheetController.popoverPresentationController?.sourceView = yourSourceViewName // works for both iPhone & iPad
present(actionSheetController, animated: true) {
print("option menu presented")
}
You'll also get this error if your target element is inside a hidden element. If this is your HTML:
<div *ngIf="false">
<span #sp>Hello World</span>
</div>
Your @ViewChild('sp') sp
will be undefined.
In such a case, then don't use *ngIf
.
Instead use a class to show/hide your element being hidden.
<div [class.show]="shouldShow">...</div>
You can try using https://ip-api.io - geo location api that returns country among other IP information.
For example with Node.js
const request = require('request-promise')
request('http://ip-api.io/api/json/1.2.3.4')
.then(response => console.log(JSON.parse(response)))
.catch(err => console.log(err))
I have this grid class that can be used as a simple matrix if you don't need any mathematical operators.

This might work for you (GNU sed):
sed -ri '/\s+$/s///' file
This looks for whitespace at the end of the line and and if present removes it.
Another Solution in Case You Don't Have Control Over Dynamic Content
This works if you didn't load your element through a directive (ie. like in the example in the commented jsfiddles).
Wrap up Your Content
Wrap your content in a div so that you can select it if you are using JQuery. You an also opt to use native javascript to get your element.
<div class="selector">
<grid-filter columnname="LastNameFirstName" gridname="HomeGrid"></grid-filter>
</div>
Use Angular Injector
You can use the following code to get a reference to $compile if you don't have one.
$(".selector").each(function () {
var content = $(this);
angular.element(document).injector().invoke(function($compile) {
var scope = angular.element(content).scope();
$compile(content)(scope);
});
});
Summary
The original post seemed to assume you had a $compile reference handy. It is obviously easy when you have the reference, but I didn't so this was the answer for me.
One Caveat of the previous code
If you are using a asp.net/mvc bundle with minify scenario you will get in trouble when you deploy in release mode. The trouble comes in the form of Uncaught Error: [$injector:unpr] which is caused by the minifier messing with the angular javascript code.
Here is the way to remedy it:
Replace the prevous code snippet with the following overload.
...
angular.element(document).injector().invoke(
[
"$compile", function($compile) {
var scope = angular.element(content).scope();
$compile(content)(scope);
}
]);
...
This caused a lot of grief for me before I pieced it together.
To install android studio on ubuntu here is the simplest way possible:
First of all, you have to install Ubuntu Make before installing Android Studio. Type following commands in the same order one by one on terminal:
1) sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-make
2) sudo apt-get update
3) sudo apt-get install ubuntu-make
Now since you are done with Ubuntu make, use below command to install Android Studio:
4) umake android
While installation it will give you a couple of option which you can handle. So, Installation is done. You can open it and run an App of your choice. Isn’t it very easy? Let me know if you go through any problem, I can help.

When you're creating the table, you can create an IDENTITY
column as follows:
CREATE TABLE (
ID_column INT NOT NULL IDENTITY(1,1) PRIMARY KEY,
...
);
The IDENTITY
property will auto-increment the column up from number 1. (Note that the data type of the column has to be an integer.) If you want to add this to an existing column, use an ALTER TABLE
command.
Edit:
Tested a bit, and I can't find a way to change the Identity properties via the Column Properties window for various tables. I guess if you want to make a column an identity column, you HAVE to use an ALTER TABLE
command.
I'm using @foreach
when I send an entity that contains a list of entities ( for example to display 2 grids in 1 view )
For example if I'm sending as model the entity Foo that contains Foo1(List<Foo1>)
and Foo2(List<Foo2>)
I can refer to the first List with:
@foreach (var item in Model.Foo.Foo1)
{
@Html.DisplayFor(modelItem=> item.fooName)
}
Just use the sys.getsizeof function defined in the sys
module.
sys.getsizeof(object[, default])
:Return the size of an object in bytes. The object can be any type of object. All built-in objects will return correct results, but this does not have to hold true for third-party extensions as it is implementation specific.
Only the memory consumption directly attributed to the object is accounted for, not the memory consumption of objects it refers to.
The
default
argument allows to define a value which will be returned if the object type does not provide means to retrieve the size and would cause aTypeError
.
getsizeof
calls the object’s__sizeof__
method and adds an additional garbage collector overhead if the object is managed by the garbage collector.See recursive sizeof recipe for an example of using
getsizeof()
recursively to find the size of containers and all their contents.
Usage example, in python 3.0:
>>> import sys
>>> x = 2
>>> sys.getsizeof(x)
24
>>> sys.getsizeof(sys.getsizeof)
32
>>> sys.getsizeof('this')
38
>>> sys.getsizeof('this also')
48
If you are in python < 2.6 and don't have sys.getsizeof
you can use this extensive module instead. Never used it though.
It is configured to use localhost:25
for the mail server.
The error message says that it can't connect to localhost:25
.
Therefore you have two options:
I can think of 2 ways to achieve this:
IFNULL():
The IFNULL() function returns a specified value if the expression is NULL.If the expression is NOT NULL, this function returns the expression.
Syntax:
IFNULL(expression, alt_value)
Example of IFNULL() with your query:
SELECT AVG( price )
FROM(
SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
WHERE listing_Type = 'AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
AND IFNULL( price, 0 ) > ( SELECT AVG( IFNULL( price, 0 ) )* 0.50
FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
FROM web_price_scan
WHERE listing_Type='AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
) g
WHERE cume_dist < 0.50
)
AND IFNULL( price, 0 ) < ( SELECT AVG( IFNULL( price, 0 ) ) *2
FROM( SELECT *, cume_dist() OVER ( ORDER BY price desc )
FROM web_price_scan
WHERE listing_Type='AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
) d
WHERE cume_dist < 0.50)
)s
HAVING COUNT(*) > 5
COALESCE()
The COALESCE() function returns the first non-null value in a list.
Syntax:
COALESCE(val1, val2, ...., val_n)
Example of COALESCE() with your query:
SELECT AVG( price )
FROM(
SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
WHERE listing_Type = 'AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
AND COALESCE( price, 0 ) > ( SELECT AVG( COALESCE( price, 0 ) )* 0.50
FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
FROM web_price_scan
WHERE listing_Type='AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
) g
WHERE cume_dist < 0.50
)
AND COALESCE( price, 0 ) < ( SELECT AVG( COALESCE( price, 0 ) ) *2
FROM( SELECT *, cume_dist() OVER ( ORDER BY price desc )
FROM web_price_scan
WHERE listing_Type='AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
) d
WHERE cume_dist < 0.50)
)s
HAVING COUNT(*) > 5
I would probably use:
for x in xyz:
if x not in a:
print x...
You can go with inserting data push, this is going to be doing in order
var arr = Array();
function arrAdd(value){
arr.push(value);
}
I'm going to try this the following way. I've placed the count variable inside the "onfocus" function so as to keep it from becoming a global variable. The idea is to create a counter for each image in a tumblr blog.
$(document).ready(function() {
$("#image1").onfocus(function() {
var count;
if (count == undefined || count == "" || count == 0) {
var count = 0;
}
count++;
$("#counter1").html("Image Views: " + count);
}
});
Then, outside the script tags and in the desired place in the body I'll add:
<div id="counter1"></div>
Also, from ojdbc14 to ojdbc6, several types (e.g., OracleResultSet
, OracleStatement
) moved from package oracle.jdbc.driver
to oracle.jdbc
.
our project surely is configured as "library" thats why you get the message : "Android library projects cannot be launched."
right-click in your project and select Properties. In the Properties window -> "Android" -> uncheck the option "is Library" and apply -> Click "ok" to close the properties window.
If our CustomTableSeeder is in same directory with DatabaseSeeder we should use like below:
$this->call('database\seeds\CustomTableSeeder');
in our DatabaseSeeder File; then another error will be thrown that says: 'DB Class not found' then we should add our DB facade to our CustomTableSeeder File like below:
use Illuminate\Support\Facades\DB;
it worked for me!
Had a similar situation myself. I think it is best to create the tar elsewhere and then use -C to tell tar the base directory for the compressed files. Example:
tar -cjf workspace.tar.gz -C <path_to_workspace> $(ls -A <path_to_workspace>)
This way there is no need to exclude your own tarfile. As noted in other comments, -A will list hidden files.
Two possible approaches:
I don't think popen()
is part of the C++ standard (it's part of POSIX from memory), but it's available on every UNIX I've worked with (and you seem to be targeting UNIX since your command is ./some_command
).
On the off-chance that there is no popen()
, you can use system("./some_command >/tmp/some_command.out");
, then use the normal I/O functions to process the output file.
If you use plain logs - all your log records should correspond this rule: one record = one line
. Following this rule you can use grep
and other tools to process your log files.
But traceback information is multi-line. So my answer is an extended version of solution proposed by zangw above in this thread. The problem is that traceback lines could have \n
inside, so we need to do an extra work to get rid of this line endings:
import logging
logger = logging.getLogger('your_logger_here')
def log_app_error(e: BaseException, level=logging.ERROR) -> None:
e_traceback = traceback.format_exception(e.__class__, e, e.__traceback__)
traceback_lines = []
for line in [line.rstrip('\n') for line in e_traceback]:
traceback_lines.extend(line.splitlines())
logger.log(level, traceback_lines.__str__())
After that (when you'll be analyzing your logs) you could copy / paste required traceback lines from your log file and do this:
ex_traceback = ['line 1', 'line 2', ...]
for line in ex_traceback:
print(line)
Profit!
We have another way to find out the number of rows in a table without running a select
query on that table.
Every MySQL instance has information_schema database. If you run the following query, it will give complete details about the table including the approximate number of rows in that table.
select * from information_schema.TABLES where table_name = 'table_name'\G
The LDF file holds the database transaction log. See, for example, http://www.databasedesign-resource.com/sql-server-transaction-log.html for a full explanation. There are ways to shrink the transaction file; for example, see http://support.microsoft.com/kb/873235.
Another option that may be useful is a dedicated HTTP debugging tool. There's a few available, I'd suggest HTTP Toolkit: an open-source project I've been working on (yeah, I might be biased) to solve this same problem for myself.
The main difference is usability & power. The Chrome dev tools are good for simple things, and I'd recommend starting there, but if you're struggling to understand the information there, and you need either more explanation or more power then proper focused tools can be useful!
For this case, it'll show you the full POST body you're looking for, with a friendly editor and highlighting (all powered by VS Code) so you can dig around. It'll give you the request & response headers of course, but with extra info like docs from MDN (the Mozilla Developer Network) for every standard header and status code you can see.
A picture is worth a thousand StackOverflow answers:
There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.
Similarity::Similarity()
or Similarity::~Similarity()
are just missing and you have defined the others incorrectly,
void Similarity::readData(Scanner& inStream){
}
not
void readData(Scanner& inStream){
}
etc. etc.
The second one is a function called readData, only the first is the readData method of the Similarity class.
To be clear about this, in Similarity.h
void readData(Scanner& inStream);
but in Similarity.cpp
void Similarity::readData(Scanner& inStream){
}
If your project name contain '-'. Remove it and try. This can cause problem in running 'ng'.
Use microtime(true)
in PHP 5, or the following modification in PHP 4:
array_sum(explode(' ', microtime()));
A portable way to write that code would be:
function getMicrotime()
{
if (version_compare(PHP_VERSION, '5.0.0', '<'))
{
return array_sum(explode(' ', microtime()));
}
return microtime(true);
}
Well, one classic example is where you wanted to get a list of employees and their immediate managers:
select e.employee as employee, b.employee as boss
from emptable e, emptable b
where e.manager_id = b.empolyee_id
order by 1
It's basically used where there is any relationship between rows stored in the same table.
And so on...
if the content of foo.py
print __name__
if __name__ == '__main__':
print 'XXXX'
A file foo.py can be used in two ways.
- imported in another file :
import foo
In this case __name__
is foo
, the code section does not get executed and does not print XXXX
.
- executed directly :
python foo.py
When it is executed directly, __name__
is same as __main__
and the code in that section is executed and prints XXXX
One of the use of this functionality to write various kind of unit tests within the same module.
Sub LockCells()
Range("A1:A1").Select

DECLARE @INPUT VARCHAR(5) = '0.12',@INPUT_1 VARCHAR(5)='0.12x';
select CONVERT(float, @INPUT) YOUR_QUERY ,
case when isnumeric(@INPUT_1)=1 THEN CONVERT(float, @INPUT_1) ELSE 0 END AS YOUR_QUERY_ANSWERED
above will return values
however below query wont work
DECLARE @INPUT VARCHAR(5) = '0.12',@INPUT_1 VARCHAR(5)='0.12x';
select CONVERT(float, @INPUT) YOUR_QUERY ,
case when isnumeric(@INPUT_1)=1 THEN CONVERT(float, @INPUT_1) ELSE **@INPUT_1** END AS YOUR_QUERY_ANSWERED
as @INPUT_1 actually has varchar in it.
So your output column must have a varchar in it.
Below is an elegant hack that covers all the Ifs
. This is for local services only.
public final class AService extends Service {
private static AService mInstance = null;
public static boolean isServiceCreated() {
try {
// If instance was not cleared but the service was destroyed an Exception will be thrown
return mInstance != null && mInstance.ping();
} catch (NullPointerException e) {
// destroyed/not-started
return false;
}
}
/**
* Simply returns true. If the service is still active, this method will be accessible.
* @return
*/
private boolean ping() {
return true;
}
@Override
public void onCreate() {

Read this section of Laravel doc : http://laravel.com/docs/eloquent#mass-assignment
Laravel provides by default a protection against mass assignment security issues. That's why you have to manually define which fields could be "mass assigned" :
class User extends Model
{
protected $fillable = ['username', 'email', 'password'];
}
Warning : be careful when you allow the mass assignment of critical fields like password
or role
. It could lead to a security issue because users could be able to update this fields values when you don't want to.
It looks like you were on the right track... The ^
character matches beginning-of-line, and $
matches end-of-line. Jonathan's pattern will work for you... just wanted to give you the explanation behind it
Something that has not been mentioned which I believe is useful, if you have two versions of Python installed e.g. both 3.8 and 3.5 there might be two folders called site-packages on your machine. In that case you can specify the python version by using the following:
py -3.5 -c "import site; print(site.getsitepackages()[1])
requestDispatcher - forward() method
When we use the
forward
method, the request is transferred to another resource within the same server for further processing.In the case of
forward
, the web container handles all processing internally and the client or browser is not involved.When
forward
is called on therequestDispatcher
object, we pass the request and response objects, so our old request object is present on the new resource which is going to process our request.Visually, we are not able to see the forwarded address, it is transparent.
Using the
forward()
method is faster thansendRedirect
.When we redirect using forward, and we want to use the same data in a new resource, we can use
request.setAttribute()
as we have a request object available.SendRedirect
In case of
sendRedirect
, the request is transferred to another resource, to a different domain, or to a different server for further processing.When you use
sendRedirect
, the container transfers the request to the client or browser, so the URL given inside thesendRedirect
method is visible as a new request to the client.In case of
sendRedirect
call, the old request and response objects are lost because it’s treated as new request by the browser.In the address bar, we are able to see the new redirected address. It’s not transparent.
sendRedirect
is slower because one extra round trip is required, because a completely new request is created and the old request object is lost. Two browser request are required.But in
sendRedirect
, if we want to use the same data for a new resource we have to store the data in session or pass along with the URL.Which one is good?
Its depends upon the scenario for which method is more useful.
If you want control is transfer to new server or context, and it is treated as completely new task, then we go for
sendRedirect
. Generally, a forward should be used if the operation can be safely repeated upon a browser reload of the web page and will not affect the result.

How does it work for command-line Git?
If you are using SSH for Git authentication, rest easy: you don't need to do anything. If you are using HTTPS Git, instead of entering your password, enter a personal access token. These can be created by going to your personal access tokens page.
As others already pointed out you can use SharedPreferences generally but if you would like to store data encrypted it's a bit inconvenient. Fortunately, there is an easier and quicker way to encrypt data now since there is an implementation of SharedPreferences that encrypts keys and values. You can use EncryptedSharedPreferences in Android JetPack Security.
Just add AndroidX Security into your build.gradle:
implementation 'androidx.security:security-crypto:1.0.0-rc01'
And you can use it like this:
String masterKeyAlias = MasterKeys.getOrCreate(MasterKeys.AES256_GCM_SPEC);
SharedPreferences sharedPreferences = EncryptedSharedPreferences.create(
"secret_shared_prefs",
masterKeyAlias,
context,
EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,
EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM
);
// use the shared preferences and editor as you normally would
SharedPreferences.Editor editor = sharedPreferences.edit();
See more details: https://android-developers.googleblog.com/2020/02/data-encryption-on-android-with-jetpack.html
Official docs: https://developer.android.com/reference/androidx/security/crypto/EncryptedSharedPreferences
You just need to put your war file in webapps and then start your server.
it will get deployed.
otherwise you can also use tomcat manager a webfront to upload & deploy your war remotely.
In swift 3, you can use this
var enumValue = Customer.Physics
var str = String(describing: enumValue)

Do not hesitate to put constraints on the database. You'll be sure to have a consistent database, and that's one of the good reasons to use a database. Especially if you have several applications requesting it (or just one application but with a direct mode and a batch mode using different sources).
With MySQL you do not have advanced constraints like you would have in postgreSQL but at least the foreign key constraints are quite advanced.
We'll take an example, a company table with a user table containing people from theses company
CREATE TABLE COMPANY (
company_id INT NOT NULL,
company_name VARCHAR(50),
PRIMARY KEY (company_id)
) ENGINE=INNODB;
CREATE TABLE USER (
user_id INT,
user_name VARCHAR(50),
company_id INT,
INDEX company_id_idx (company_id),
FOREIGN KEY (company_id) REFERENCES COMPANY (company_id) ON...
) ENGINE=INNODB;
Let's look at the ON UPDATE clause:
And now on the ON DELETE side:
usually my default is: ON DELETE RESTRICT ON UPDATE CASCADE. with some ON DELETE CASCADE
for track tables (logs--not all logs--, things like that) and ON DELETE SET NULL
when the master table is a 'simple attribute' for the table containing the foreign key, like a JOB table for the USER table.
Edit
It's been a long time since I wrote that. Now I think I should add one important warning. MySQL has one big documented limitation with cascades. Cascades are not firing triggers. So if you were over confident enough in that engine to use triggers you should avoid cascades constraints.
MySQL triggers activate only for changes made to tables by SQL statements. They do not activate for changes in views, nor by changes to tables made by APIs that do not transmit SQL statements to the MySQL Server
==> See below the last edit, things are moving on this domain
Triggers are not activated by foreign key actions.
And I do not think this will get fixed one day. Foreign key constraints are managed by the InnoDb storage and Triggers are managed by the MySQL SQL engine. Both are separated. Innodb is the only storage with constraint management, maybe they'll add triggers directly in the storage engine one day, maybe not.
But I have my own opinion on which element you should choose between the poor trigger implementation and the very useful foreign keys constraints support. And once you'll get used to database consistency you'll love PostgreSQL.
as stated by @IstiaqueAhmed in the comments, the situation has changed on this subject. So follow the link and check the real up-to-date situation (which may change again in the future).
Thanks to this question. I wanted the exact opposite, i.e a hidden div should still occupy its space on the browser. So, I used visibility: hidden
instead of display: none

I am not sure,how you are opening popup or say model in your code. But you can try something like this..
<html ng-app="MyApp">
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<link rel="stylesheet" href="css/bootstrap.min.css" />
<script type="text/javascript">
var myApp = angular.module("MyApp", []);
myApp.controller('MyController', function ($scope) {
$scope.open = function(){
var modalInstance = $modal.open({
templateUrl: '/assets/yourOpupTemplatename.html',
backdrop:'static',
keyboard:false,
controller: function($scope, $modalInstance) {
$scope.cancel = function() {
$modalInstance.dismiss('cancel');
};
$scope.ok = function () {
$modalInstance.close();
};
}
});
}
});
</script>
</head>
<body ng-controller="MyController">
<button class="btn btn-primary" ng-click="open()">Test Modal</button>
<!-- Confirmation Dialog -->
<div class="modal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">

<h4 class="modal-title">Delete confirmation</h4>
</div>
<div class="modal-body">
<p>Are you sure?</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" ng-click="cancel()">No</button>
<button type="button" class="btn btn-primary" ng-click="ok()">Yes</button>

you can use indexOf
method from lodash
var tv = [{id:1},{id:2}]
var voteID = 2;
var data = _.find(tv, function(voteItem){ return voteItem.id == voteID; });
var index=_.indexOf(tv,data);
You can run the script with python -m
from the relevant root dir. And pass the "modules path" as argument.
Example: $ python -m module.sub_module.main # Notice there is no '.py' at the end.
Another example:
$ tree # Given this file structure
.
+-- bar
¦ +-- __init__.py
¦ +-- mod.py
+-- foo
+-- __init__.py
+-- main.py
$ cat foo/main.py
from bar.mod import print1
print1()
$ cat bar/mod.py
def print1():
print('In bar/mod.py')
$ python foo/main.py # This gives an error
Traceback (most recent call last):
File "foo/main.py", line 1, in <module>
from bar.mod import print1
ImportError: No module named bar.mod
$ python -m foo.main # But this succeeds
In bar/mod.py
Try
'user_id' => auth()->id
or
'user_id' => Auth::user()->id
instead of
'user_id' => auth()->id()
This is how I did it.
It may be faster because it is using execute_batch
:
# df is the dataframe
if len(df) > 0:
df_columns = list(df)
# create (col1,col2,...)
columns = ",".join(df_columns)
# create VALUES('%s', '%s",...) one '%s' per column
values = "VALUES({})".format(",".join(["%s" for _ in df_columns]))
#create INSERT INTO table (columns) VALUES('%s',...)
insert_stmt = "INSERT INTO {} ({}) {}".format(table,columns,values)
cur = conn.cursor()
psycopg2.extras.execute_batch(cur, insert_stmt, df.values)
conn.commit()
cur.close()
I'd recommend that you take a look at java.util.ResourceBundle. You should care about I18N, but it's worth it even if you don't. Externalizing the messages is a very good idea. I've found that it was useful to be able to give a spreadsheet to business folks that allowed them to put in the exact language they wanted to see. We wrote an Ant task to generate the .properties files at compile time. It makes I18N trivial.
If you're also using Spring, so much the better. Their MessageSource class is useful for these sorts of things.
If your values are hashable (ie. strings), then you can simply compare the ItemsView of the two dicts.
https://docs.python.org/3/library/stdtypes.html#dict-views
set_with_unique_key_value_pairs = dict1.items() ^ dict2.items()
set_with_matching_key_value_pairs = dict1.items() & dict2.items()
Any set
operations are available to you.
Since you might not care about keys in this case, you can also just use the ValuesView (again, provided the values are hashable).
set_with_matching_values = dict1.values() & dict2.values()
-w

You need the following code below. At a glance, this may look like any old code that I made up. However, what I did was look at the source code for http://grepcode.com/file/repo1.maven.org/maven2/mysql/mysql-connector-java/5.1.31/com/mysql/jdbc/PreparedStatement.java. Then after that, I carefully looked through the code of setString(int parameterIndex, String x) to find the characters which it escapes and customised this to my own class so that it can be used for the purposes that you need. After all, if this is the list of characters that Oracle escapes, then knowing this is really comforting security-wise. Maybe Oracle need a nudge to add a method similar to this one for the next major Java release.
public class SQLInjectionEscaper {
public static String escapeString(String x, boolean escapeDoubleQuotes) {
StringBuilder sBuilder = new StringBuilder(x.length() * 11/10);
int stringLength = x.length();
for (int i = 0; i < stringLength; ++i) {
char c = x.charAt(i);
switch (c) {
case 0: /* Must be escaped for 'mysql' */
sBuilder.append('\\');
sBuilder.append('0');
break;
case '\n': /* Must be escaped for logs */
sBuilder.append('\\');
sBuilder.append('n');
break;
case '\r':
sBuilder.append('\\');
sBuilder.append('r');
break;
case '\\':
sBuilder.append('\\');
sBuilder.append('\\');
break;
case '\'':
sBuilder.append('\\');
sBuilder.append('\'');
break;
case '"': /* Better safe than sorry */
if (escapeDoubleQuotes) {
sBuilder.append('\\');
}
sBuilder.append('"');
break;
case '\032': /* This gives problems on Win32 */
sBuilder.append('\\');
sBuilder.append('Z');
break;
case '\u00a5':
case '\u20a9':
// escape characters interpreted as backslash by mysql
// fall through
default:
sBuilder.append(c);
}
}
return sBuilder.toString();
}
}
What you're asking about is called Variable Variables. All you need to do is store your string in a variable and access it like so:
$Class = 'MyCustomClass';
$Property = 'Name';
$List = array('Name');
$Object = new $Class();
// All of these will echo the same property
echo $Object->$Property; // Evaluates to $Object->Name
echo $Object->{$List[0]}; // Use if your variable is in an array
return (expression) ? value1 : value2;
If value1
and value2
are actually true
and false
like in your example, you may as well just
return expression;
This is an Inequality operator.

I solved this problem by changing the data type. If you see the 'Energy Supply per Capita' is a numerical type while the 'Citable docs per Capita' is an object type. I converted the column to float using astype. I had the same problem with some np functions: count_nonzero
and sum
worked while mean
and std
didn't.
You could use loc
to get series which satisfying your condition and then iloc
to get first element:

3 p2 4
In [3]: df.loc[df['B'] == 3, 'A']
Out[3]:

Name: A, dtype: object
In [4]: df.loc[df['B'] == 3, 'A'].iloc[0]
Out[4]: 'p3'

I noticed that there is no selected feature in datalist. It only gives you choice but can't have a default option. You can't show the selected option on the next page either.
It's easy to do. The cURL code that's on the page that Elad Nava has put here works. Elad has commented about the error he's receiving.
String describing an error that occurred while processing the message for that recipient. The possible values are the same as documented in the above table, plus "Unavailable" (meaning GCM servers were busy and could not process the message for that particular recipient, so it could be retried).
I've got a service set up already that seems to be working (ish), and so far all I've had back are unavailable returns from Google. More than likely this will change soon.
To answer the question, use PHP, make sure the Zend Framework is in your include path, and use this code:
<?php
ini_set('display_errors',1);
include"Zend/Loader/Autoloader.php";
Zend_Loader_Autoloader::getInstance();
$url = 'https://android.googleapis.com/gcm/send';
$serverApiKey = "YOUR API KEY AS GENERATED IN API CONSOLE";
$reg = "DEVICE REGISTRATION ID";
$data = array(
'registration_ids' => array($reg),
'data' => array('yourname' => 'Joe Bloggs')
);
print(json_encode($data));
$client = new Zend_Http_Client($url);
$client->setMethod('POST');
$client->setHeaders(array("Content-Type" => "application/json", "Authorization" => "key=" . $serverApiKey));
$client->setRawData(json_encode($data));
$request = $client->request('POST');
$body = $request->getBody();
$headers = $request->getHeaders();
print("<xmp>");
var_dump($body);
var_dump($headers);
And there we have it. A working (it will work soon) example of using Googles new GCM in Zend Framework PHP.
In my case it worked to update the MSTest nuget packages. Could reproduce this problem even on blank MSTest project and updating the packages worked.
You could unregister the control with
regsvr32 /u badboy.ocx
at the command line. Though i would suggest testing these things in a vmware.

is usedA callback is some code that you pass to a given method, so that it can be called at a later time.
In Java one obvious example is java.util.Comparator
. You do not usually use a Comparator
directly; rather, you pass it to some code that calls the Comparator
at a later time:
Example:
class CodedString implements Comparable<CodedString> {
private int code;
private String text;
...
@Override
public boolean equals() {
// member-wise equality
}
@Override
public int hashCode() {
// member-wise equality
}
@Override
public boolean compareTo(CodedString cs) {
// Compare using "code" first, then
// "text" if both codes are equal.
}
}
...
public void sortCodedStringsByText(List<CodedString> codedStrings) {
Comparator<CodedString> comparatorByText = new Comparator<CodedString>() {
@Override
public int compare(CodedString cs1, CodedString cs2) {
// Compare cs1 and cs2 using just the "text" field
}
}
// Here we pass the comparatorByText callback to Collections.sort(...)
// Collections.sort(...) will then call this callback whenever it
// needs to compare two items from the list being sorted.
// As a result, we will get the list sorted by just the "text" field.
// If we do not pass a callback, Collections.sort will use the default
// comparison for the class (first by "code", then by "text").
Collections.sort(codedStrings, comparatorByText);
}
There are a several ways of declaring variables in SQL*Plus scripts.
The first is to use VAR, to declare a bind variable. The mechanism for assigning values to a VAR is with an EXEC call:
SQL> var name varchar2(20)
SQL> exec :name := 'SALES'
PL/SQL procedure successfully completed.
SQL> select * from dept
2 where dname = :name
3 /
DEPTNO DNAME LOC
---------- -------------- -------------
30 SALES CHICAGO
SQL>
A VAR is particularly useful when we want to call a stored procedure which has OUT parameters or a function.
Alternatively we can use substitution variables. These are good for interactive mode:
SQL> accept p_dno prompt "Please enter Department number: " default 10
Please enter Department number: 20
SQL> select ename, sal
2 from emp
3 where deptno = &p_dno
4 /
old 3: where deptno = &p_dno
new 3: where deptno = 20
ENAME SAL
---------- ----------
CLARKE 800
ROBERTSON 2975
RIGBY 3000
KULASH 1100
GASPAROTTO 3000
SQL>
When we're writing a script which calls other scripts it can be useful to DEFine the variables upfront. This snippet runs without prompting me to enter a value:
SQL> def p_dno = 40
SQL> select ename, sal
2 from emp
3 where deptno = &p_dno
4 /
old 3: where deptno = &p_dno
new 3: where deptno = 40
no rows selected
SQL>
Finally there's the anonymous PL/SQL block. As you see, we can still assign values to declared variables interactively:
SQL> set serveroutput on size unlimited
SQL> declare
2 n pls_integer;
3 l_sal number := 3500;
4 l_dno number := &dno;
5 begin
6 select count(*)
7 into n
8 from emp
9 where sal > l_sal
10 and deptno = l_dno;
11 dbms_output.put_line('top earners = '||to_char(n));
12 end;
13 /
Enter value for dno: 10
old 4: l_dno number := &dno;
new 4: l_dno number := 10;
top earners = 1
PL/SQL procedure successfully completed.

bash
does not abort the running execution in case something detects an error state (unless you set the -e
flag). Programming languages which offer try/catch
do this in order to inhibit a "bailing out" because of this special situation (hence typically called "exception").
In the bash
, instead, only the command in question will exit with an exit code greater than 0, indicating that error state. You can check for that of course, but since there is no automatic bailing out of anything, a try/catch does not make sense. It is just lacking that context.
You can, however, simulate a bailing out by using sub shells which can terminate at a point you decide:
(
echo "Do one thing"
echo "Do another thing"
if some_condition
then
exit 3 # <-- this is our simulated bailing out
fi
echo "Do yet another thing"
echo "And do a last thing"
) # <-- here we arrive after the simulated bailing out, and $? will be 3 (exit code)
if [ $? = 3 ]
then
echo "Bail out detected"
fi
Instead of that some_condition
with an if
you also can just try a command, and in case it fails (has an exit code greater than 0), bail out:
(
echo "Do one thing"
echo "Do another thing"
some_command || exit 3
echo "Do yet another thing"
echo "And do a last thing"
)
...
Unfortunately, using this technique you are restricted to 255 different exit codes (1..255) and no decent exception objects can be used.
If you need more information to pass along with your simulated exception, you can use the stdout of the subshells, but that is a bit complicated and maybe another question ;-)
Using the above mentioned -e
flag to the shell you can even strip that explicit exit
statement:
(
set -e
echo "Do one thing"
echo "Do another thing"
some_command
echo "Do yet another thing"
echo "And do a last thing"
)
...

To all the great answers, I want to add a small detail:
If You write plugins (e.g. DLLs or .so libraries to be loaded by a CAD system), then static is a life saver that avoids name collisions like this one:
Even worse: Step 3 may behave differently depending on compiler optimization, plugin load mechanism, etc.
I had this issue once with two helper functions (same name, different behaviour) in two plugins. Declaring them static solved the problem.
I know the OP is asking for a mysql
answer but since I found the other answers not working for me,

So to save time for others like me, just index the row after retrieving them from database
example in PHP:
$users = UserRepository::loadAllUsersAndSortByScore();
foreach($users as $index=>&$user){
$user['rank'] = $index+1;
}
example in PHP using offset and limit for paging:
$limit = 20; //page size
$offset = 3; //page number
$users = UserRepository::loadAllUsersAndSortByScore();
foreach($users as $index=>&$user){
$user['rank'] = $index+1+($limit*($offset-1));
}
You should use the .offsetWidth
and .offsetHeight
properties.
Note they belong to the element, not .style
.
var width = document.getElementById('foo').offsetWidth;
Function .getBoundingClientRect()
returns dimensions and location of element as floating-point numbers after performing CSS transforms.
> console.log(document.getElementById('id').getBoundingClientRect())
DOMRect {
bottom: 177,
height: 54.7,
left: 278.5,?
right: 909.5,
top: 122.3,
width: 631,
x: 278.5,
y: 122.3,
}
Try CSS:
<h2 style="color:#069">Process Report</h2>
If you have more than one h2 tags which should have the same color add a style tag to the head tag like this:
<style type="text/css">
h2 {
color:#069;
}
</style>
Using ONLY css is impossbile. In fact, all form elements are impossible to customize to look in the same way on all browsers only with css. You can try niceforms though ;)
Suppose your query is "select id,name from users where rollNo = 1001".
Here query will return a object with id and name column. Your Response class is like bellow:
public class UserObject{
int id;
String name;
String rollNo;
public UserObject(Object[] columns) {
this.id = (columns[0] != null)?((BigDecimal)columns[0]).intValue():0;
this.name = (String) columns[1];
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getRollNo() {
return rollNo;
}
public void setRollNo(String rollNo) {
this.rollNo = rollNo;
}
}
here UserObject
constructor will get a Object Array and set data with object.
public UserObject(Object[] columns) {
this.id = (columns[0] != null)?((BigDecimal)columns[0]).intValue():0;
this.name = (String) columns[1];
}
Your query executing function is like bellow :
public UserObject getUserByRoll(EntityManager entityManager,String rollNo) {
String queryStr = "select id,name from users where rollNo = ?1";
try {
Query query = entityManager.createNativeQuery(queryStr);
query.setParameter(1, rollNo);
return new UserObject((Object[]) query.getSingleResult());
} catch (Exception e) {
e.printStackTrace();
throw e;
}
}
Here you have to import bellow packages:
import javax.persistence.Query;
import javax.persistence.EntityManager;
Now your main class, you have to call this function.
First you have to get EntityManager and call this getUserByRoll(EntityManager entityManager,String rollNo)
function. Calling procedure is given bellow:
@PersistenceContext
private EntityManager entityManager;
UserObject userObject = getUserByRoll(entityManager,"1001");
Now you have data in this userObject.
Here is Imports
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
Note:
query.getSingleResult() return a array. You have to maintain the column position and data type.
select id,name from users where rollNo = ?1
query return a array and it's [0] --> id and [1] -> name
.

For iTunes 12.7.0 and above, you just need to Cmd+c your app and Cmd+v into your device on iTunes. Any tab works, including Summary, Music, Movies.
Agreed with @jolvi, @ArundasR, and others, the warning happens on a member function that doesn't use self
.
If you're sure PyCharm is wrong, that the function should not be a @staticmethod
, and if you value zero warnings, you can make this one go away two different ways:
Workaround #1
def bar(self):
self.is_not_used()
doing_something_without_self()
def is_not_used(self):
pass
Workaround #2 [Thanks @DavidPärsson]
# noinspection PyMethodMayBeStatic
def bar(self):
doing_something_without_self()
The application I had for this (the reason I could not use @staticmethod) was in making a table of handler functions for responding to a protocol subtype field. All handlers had to be the same form of course (static or nonstatic). But some didn't happen to do anything with the instance. If I made those static I'd get "TypeError: 'staticmethod' object is not callable".
In support of the OP's consternation, suggesting you add staticmethod whenever you can, goes against the principle that it's easier to make code less restrictive later, than to make it more -- making a method static makes it less restrictive now, in that you can call class.f() instead of instance.f().
Guesses as to why this warning exists:
This feature was added in Compose 1.6.

Had the same issue, a 404 response for the web api controllers when served from the IIS but everything worked fine from VS2010. None of the above solutions worked for me. Eventually I found that the problem was that we added WSE 3.0 support for the application and the Microsoft.Web.Services3 dll was missing in the application's /bin directory. Weird, but after copying the dll, the route mapping started to work.
Use this function to cast a float value from any kind of text style:
function parseFloat($value) {
return floatval(preg_replace('#^([-]*[0-9\.,\' ]+?)((\.|,){1}([0-9-]{1,3}))*$#e', "str_replace(array('.', ',', \"'\", ' '), '', '\\1') . '.\\4'", $value));
}
This solution is not dependant on any locale settings. Thus for user input users can type float values in any way they like. This is really helpful e.g. when you have a project wich is in english only but people all over the world are using it and might not have in mind that the project wants a dot instead of a comma for float values. You could throw javascript in the mix and fetch the browsers default settings but still many people set these values to english but still typing 1,25 instead of 1.25 (especially but not limited to the translation industry, research and IT)
In case someone being a beginner who tried all of the above and still didn't manage to get the project to work. Check your namespace. In an instance where you copy code from one project to another and you forget to change the namespace of the project then it will also give you this error.
Hope it helps someone.

sbt
respects the usual environment variables for http proxy settings:
export JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyHost=yourserver -Dhttp.proxyPort=8080 -Dhttp.proxyUser=username -Dhttp.proxyPassword=password"

) as usual in the Windows way.)
Then run sbt
as usual:

Switching between proxy/no-proxy should be a matter of setting up a little script that you can 'slurp' in whenever you need it.
yourserver
valueyourserver
valuehttps.proxyHost
and https.proxyPort
since a lot of stuff works over httpsshred
or srm
the entire file). If you are on Windows, don't worry about it, your security is already messed up you can't do any more harm..NET Framework 3.5 has got ranges:
you can use it with "contains" and the IF statement, since like someone said the SWITCH statement uses the "==" operator.
Here an example:
int c = 2;
if(Enumerable.Range(0,10).Contains(c))
DoThing();
else if(Enumerable.Range(11,20).Contains(c))
DoAnotherThing();
But I think we can have more fun: since you won't need the return values and this action doesn't take parameters, you can easily use actions!
public static void MySwitchWithEnumerable(int switchcase, int startNumber, int endNumber, Action action)
{
if(Enumerable.Range(startNumber, endNumber).Contains(switchcase))
action();
}
The old example with this new method:
MySwitchWithEnumerable(c, 0, 10, DoThing);
MySwitchWithEnumerable(c, 10, 20, DoAnotherThing);
Since you are passing actions, not values, you should omit the parenthesis, it's very important. If you need function with arguments, just change the type of Action
to Action<ParameterType>
. If you need return values, use Func<ParameterType, ReturnType>
.
In C# 3.0 there is no easy Partial Application to encapsulate the fact the the case parameter is the same, but you create a little helper method (a bit verbose, tho).
public static void MySwitchWithEnumerable(int startNumber, int endNumber, Action action){
MySwitchWithEnumerable(3, startNumber, endNumber, action);
}
Here an example of how new functional imported statement are IMHO more powerful and elegant than the old imperative one.
Use numpy.sum
. for your case, it is
sum = a.sum(axis=0)
md5.h
also have MD5_*
functions very useful for big file
#include <openssl/md5.h>
#include <fstream>
.......
std::ifstream file(filename, std::ifstream::binary);
MD5_CTX md5Context;
MD5_Init(&md5Context);
char buf[1024 * 16];
while (file.good()) {
file.read(buf, sizeof(buf));
MD5_Update(&md5Context, buf, file.gcount());
}
unsigned char result[MD5_DIGEST_LENGTH];
MD5_Final(result, &md5Context);
Very simple, isn`t it? Convertion to string also very simple:
#include <sstream>
#include <iomanip>
.......
std::stringstream md5string;
md5string << std::hex << std::uppercase << std::setfill('0');
for (const auto &byte: result)
md5string << std::setw(2) << (int)byte;
return md5string.str();
The correct thing to do is use the 'string-escape' code to decode the string.
>>> myString = "spam\\neggs"
>>> decoded_string = bytes(myString, "utf-8").decode("unicode_escape") # python3
>>> decoded_string = myString.decode('string_escape') # python2
>>> print(decoded_string)
spam

Don't use the AST or eval. Using the string codecs is much safer.

When using promises they can be used in a promise chain. async=false will be deprecated so using promises is your best option.

Just in case someone is interest only in what kind of process created the shared moeries, call

$(row).css("background-color", "Orange");
$(row).addClass("warning");
}
},
// ...
});
Perhaps you should look at adding a Settings File. (e.g. App.Settings) Creating this file will allow you to do the following:
string mysetting = App.Default.MySetting;
App.Default.MySetting = "my new setting";
This means you can edit and then change items, where the items are strongly typed, and best of all... you don't have to touch any xml before you deploy!
The result is a Application or User contextual setting.
Have a look in the "add new item" menu for the setting file.
An example statement that uses a sub-select :
select * into MyNewTable
from
(
select
*
from
[SomeOtherTablename]
where
EventStartDatetime >= '01/JAN/2018'
)
) mysourcedata
;
note that the sub query must be given a name .. any name .. e.g. above example gives the subquery a name of mysourcedata. Without this a syntax error is issued in SQL*server 2012.
The database should reply with a message like: (9999 row(s) affected)
say easily http://www.google.com/maps/place/lat,lng
format
sample url:
Use this:
import cv2
cap = cv2.VideoCapture('path to video file')
count = 0
while cap.isOpened():
ret,frame = cap.read()
cv2.imshow('window-name', frame)
cv2.imwrite("frame%d.jpg" % count, frame)
count = count + 1
if cv2.waitKey(10) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows() # destroy all opened windows
I am asking in general, how to write a compatible awk script that performs the same functionality ...
To solve the problem in your quesiton is easy. (check others' answer).
If you want to write an awk script, which portable to any awk implementations and versions (gawk/nawk/mawk...) it is really hard, even if with --posix (gawk)
for example:
\x
escape, some notFS
interpreter works differentlywell all the points above are just spoken in general. Back to your problem, you problem is only related to fundamental feature of awk. awk '{print $x}'
the line like that will work all awks.
There are two reasons why your awk line behaves differently on gawk and mawk:
your used substr()
function wrongly. this is the main cause. you have substr($0, 0, RSTART - 1)
the 0
should be 1
, no matter which awk do you use. awk array, string idx etc are 1-based.
gawk and mawk implemented substr()
differently.
Even in base Python you can do the computation in generic form
result = sum(x**2 for x in some_vector) ** 0.5
x ** 2
is surely not an hack and the computation performed is the same (I checked with cpython source code). I actually find it more readable (and readability counts).
Using instead x ** 0.5
to take the square root doesn't do the exact same computations as math.sqrt
as the former (probably) is computed using logarithms and the latter (probably) using the specific numeric instruction of the math processor.
I often use x ** 0.5
simply because I don't want to add math
just for that. I'd expect however a specific instruction for the square root to work better (more accurately) than a multi-step operation with logarithms.
For those who wants to use a simple and lightweight image:
FROM alpine:3.6
# copy crontabs for root user
COPY config/cronjobs /etc/crontabs/root
# start crond with log level 8 in foreground, output to stderr
CMD ["crond", "-f", "-d", "8"]
Where cronjobs is the file that contains your cronjobs, in this form:
* * * * * echo "hello stackoverflow" >> /test_file 2>&1
# remember to end this file with an empty new line
An example:
log4j.rootLogger=ERROR, logfile
log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.datePattern='-'dd'.log'
log4j.appender.logfile.File=log/radius-prod.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n
log4j.logger.foo.bar.Baz=DEBUG, myappender
log4j.additivity.foo.bar.Baz=false
log4j.appender.myappender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.myappender.datePattern='-'dd'.log'
log4j.appender.myappender.File=log/access-ext-dmz-prod.log
log4j.appender.myappender.layout=org.apache.log4j.PatternLayout
log4j.appender.myappender.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n
Although there were several great and helpful answers here, I didn't find one that seemed to be the right combination of performant, cross-platform, and robust; so I wanted to share the solution I wrote for my code:
#!/bin/bash
# array_contains "$needle" "${haystack[@]}"
#
# Returns 0 if an item ($1) is contained in an array ($@).
#
# Developer note:
# The use of a delimiter here leaves something to be desired. The ideal
# method seems to be to use `grep` with --line-regexp and --null-data, but
# Mac/BSD grep doesn't support --line-regexp.
function array_contains()
{
# Extract and remove the needle from $@.
local needle="$1"
shift
# Separates strings in the array for matching. Must be extremely-unlikely
# to appear in the input array or the needle.
local delimiter='#!-\8/-!#'
# Create a string with containing every (delimited) element in the array,
# and search it for the needle with grep in fixed-string mode.
if printf "${delimiter}%s${delimiter}" "$@" | \
grep --fixed-strings --quiet "${delimiter}${needle}${delimiter}"; then
return 0
fi
return 1
}
Assuming you really want an array of single-character strings (not a char[]
or Character[]
)
1. Using a regex:
public static String[] singleChars(String s) {
return s.split("(?!^)");
}
The zero width negative lookahead prevents the pattern matching at the start of the input, so you don't get a leading empty string.
2. Using Guava:
import java.util.List;
import org.apache.commons.lang.ArrayUtils;
import com.google.common.base.Functions;
import com.google.common.collect.Lists;
import com.google.common.primitives.Chars;
// ...
public static String[] singleChars(String s) {
return
Lists.transform(Chars.asList(s.toCharArray()),
Functions.toStringFunction())
.toArray(ArrayUtils.EMPTY_STRING_ARRAY);
}
I'm coming to python from R, and R's head()
function wraps lines in a really convenient way for looking at data:
> head(cbind(mtcars, mtcars, mtcars))

I developed the following little python function to mimic this functionality:
def rhead(x, nrow = 6, ncol = 4):
pd.set_option('display.expand_frame_repr', False)
seq = np.arange(0, len(x.columns), ncol)
for i in seq:
print(x.loc[range(0, nrow), x.columns[range(i, min(i+ncol, len(x.columns)))]])
pd.set_option('display.expand_frame_repr', True)
(it depends on pandas and numpy, obviously)
You can do it by using simple one line JavaScript code and also be careful that if JavaScript is turned off it will not work. The below code will do it's job if JavaScript is turned off.
Turn off JavaScript and run the code on you own file to know it's full function.(If you turn off JavaScript here, the below Code Snippet will not work)

It's not safe, not recommended, but it's possible.
I have experience in an application using the auto-update option in production.
Well, the main problems and risks found in this solution are:
So, I will not recommend to use auto-update in production.
If you really want to use auto-update in production, I recommend:
And, different of the another posts, I don't think the auto-update enabled it's related with "very well paid" DBAs (as mentioned in other posts). DBAs have more important things to do than write SQL statements to create/change/delete tables and columns. These simple everyday tasks can be done and automated by developers and only passed for DBA team to review, not needing Hibernate and DBAs "very well paid" to write them.

I solved this problem, I changed build system to Legacy Build System
from New Build System
In Xcode v10+, select File > Project Settings
In previous Xcode, select File > Workspace Settings
Change Build System to Legacy Build System
from New Build System
--> Click Done.
Just to extend on the previous answer, if you are linking two requests together and want to send the cookies returned from the first one to the second one (for example, maintaining a session alive across requests) you can do:
import requests
r1 = requests.post('http://www.yourapp.com/login')
r2 = requests.post('http://www.yourapp.com/somepage',cookies=r1.cookies)
In my case I was using spring+hibernate and forgot to run my MYSQL server due to which hibernate was not getting loaded and thus was throwing error
I didn't see this method shown, so if someone else is looking to do this I found that ggplot documentation suggested a technique for using the gam
method that produced similar results to loess
when working with small data sets.
library(ggplot2)
x <- 1:10
y <- c(2,4,6,8,7,8,14,16,18,20)
df <- data.frame(x,y)
r <- ggplot(df, aes(x = x, y = y)) + geom_smooth(method = "gam", formula = y ~ s(x, bs = "cs"))+geom_point()
r
First with the loess method and auto formula Second with the gam method with suggested formula
You can define a method in spec_helper.rb that sends a message both to Rails.logger.info and to puts and use that for debugging:
def log_test(message)
Rails.logger.info(message)
puts message
end
df = pd.DataFrame(np.arange(1,10).reshape(3,3))
df['newcol'] = pd.Series(your_2d_numpy_array)

To verify and list the fingerprint of the key (without importing it into the keyring first), type
gpg --with-fingerprint <filename>
Edit: on Ubuntu 18.04 (gpg 2.2.4) the fingerprint isn't show with the above command. Use the --with-subkey-fingerprint
option instead
gpg --with-subkey-fingerprint <filename>
You could use jQuery and an Ajax call to post the specific update back to your server with Javascript.
It would look something like this:
function updatePostID(val, comment)
{
var args = {};
args.PostID = val;
args.Comment = comment;
$.ajax({
type: "POST",
url: controllerActionMethodUrlHere,
contentType: "application/json; charset=utf-8",
data: args,
dataType: "json",
success: function(msg)
{
// Something afterwards here
}
});
}
As bmargulies mentioned:
Preferences>Java>Editor>Templates>New...
Now, type psvm then Ctrl + Space
on Mac or Windows.
For the record, you can use POSIX standard exit codes defined here.
Example:
import sys, os
try:
config()
except:
sys.exit(os.EX_CONFIG)
try:
do_stuff()
except:
sys.exit(os.EX_SOFTWARE)
sys.exit(os.EX_OK) # code 0, all ok
control-shift-L should open the log(s) for you. this will by default be the messages log, but if you create the item that is creating the error the Compiler Log will show up (for me the box shows up in the bottom middle left).
if the messages log is the only log that shows up, simply re-execute the item that was causing the failure and the compiler log will show up
for instance, hit Control-shift-L then execute this
CREATE OR REPLACE FUNCTION TEST123() IS
BEGIN
VAR := 2;
end TEST123;
and you will see the message "Error(1,18): PLS-00103: Encountered the symbol ")" when expecting one of the following: current delete exists prior "
(You can also see this in "View--Log")
One more thing, if you are having a problem with a (function || package || procedure) if you do the coding via the SQL Developer interface (by finding the object in question on the connections tab and editing it the error will be immediately displayed (and even underlined at times)
There is no default database for user. There is default database for current session.
You can get it using DATABASE() function -
SELECT DATABASE();
And you can set it using USE statement -
USE database1;
You should set it manually - USE db_name
, or in the connection string.
You can use ApplicationContextAware.
ApplicationContextAware:
Interface to be implemented by any object that wishes to be notified of the ApplicationContext that it runs in. Implementing this interface makes sense for example when an object requires access to a set of collaborating beans.
There are a few methods for obtaining a reference to the application context. You can implement ApplicationContextAware as in the following example:
package hello;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
@Component
public class ApplicationContextProvider implements ApplicationContextAware {
private ApplicationContext applicationContext;
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}
public ApplicationContext getContext() {
return applicationContext;
}
}
Update:
When Spring instantiates beans, it looks for ApplicationContextAware implementations, If they are found, the setApplicationContext() methods will be invoked.
In this way, Spring is setting current applicationcontext.
Code snippet from Spring's source code
:
private void invokeAwareInterfaces(Object bean) {
.....
.....
if (bean instanceof ApplicationContextAware) {
((ApplicationContextAware)bean).setApplicationContext(this.applicationContext);
}
}
Once you get the reference to Application context, you get fetch the bean whichever you want by using getBean().
The Error is here
lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1
wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this
lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1
Similarly
wsPOR.Range("A2:G" & lastrow).Select
should be
wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select
Try:
cl /v
Actually, any time I give cl an argument, it prints out the version number on the first line.
You could just feed it a garbage argument and then parse the first line of the output, which contains the verison number.
if(isset($_POST['form_field_name'])) {
$variable_name = $_POST['form_field_name'];
}
issuing 2 command can do the trick
DBCC CHECKIDENT ('[TestTable]', RESEED,0)
DBCC CHECKIDENT ('[TestTable]', RESEED)
the first reset the identity to zero , and the next will set it to the next available value -- jacob
If you want to get one element by row index and column name, you can do it just like df['b'][0]
. It is as simple as you can imagine.
Or you can use df.ix[0,'b']
- mixed usage of index and label.
Note: Since v0.20, ix
has been deprecated in favour of loc
/ iloc
.
I think You are using //--style="display:none"--//
for hiding the div.
Use this code:
<script>
function klikaj(i) {
document.getElementById(i).style.display = 'block';
}
</script>
<div id="thumb0" class="thumbs" onclick="klikaj('rad1')">Click Me..!</div>
<div id="rad1" class="thumbs" style="display:none">Helloooooo</div>
The headers in the answer provided by BalusC does not prevent Safari 5 (and possibly older versions as well) from displaying content from the browser cache when using the browser's back button. A way to prevent this is to add an empty onunload event handler attribute to the body tag:
<body onunload="">
This hack apparently breaks the back-forward cache in Safari: Is there a cross-browser onload event when clicking the back button?
If you don't mind including the underscore as an allowed character, you could try simply:
result = subject.replace(/\W+/g, "");
If the underscore must be excluded also, then
result = subject.replace(/[^A-Z0-9]+/ig, "");
(Note the case insensitive flag)
For there to be an overlap the table's start_date has to be LESS THAN the interval end date (i.e. it has to start before the end of the interval) AND the table's end_date has to be GREATER THAN the interval start date. You may need to use <= and >= depending on your requirements.
Thread.sleep()
is simple for the beginners and may be appropriate for unit tests and proofs of concept.
But please DO NOT use sleep()
for production code. Eventually sleep()
may bite you badly.
Best practice for multithreaded/multicore java applications to use the "thread wait" concept. Wait releases all the locks and monitors held by the thread, which allows other threads to acquire those monitors and proceed while your thread is sleeping peacefully.
Code below demonstrates that technique:
import java.util.concurrent.TimeUnit;
public class DelaySample {
public static void main(String[] args) {
DelayUtil d = new DelayUtil();
System.out.println("started:"+ new Date());
d.delay(500);
System.out.println("half second after:"+ new Date());
d.delay(1, TimeUnit.MINUTES);
System.out.println("1 minute after:"+ new Date());
}
}
DelayUtil
implementation:
import java.util.concurrent.TimeUnit;
import java.util.concurrent.locks.Condition;
import java.util.concurrent.locks.ReentrantLock;
public class DelayUtil {
/**
* Delays the current thread execution.
* The thread loses ownership of any monitors.
* Quits immediately if the thread is interrupted
*
* @param durationInMillis the time duration in milliseconds
*/
public void delay(final long durationInMillis) {
delay(durationInMillis, TimeUnit.MILLISECONDS);
}
/**
* @param duration the time duration in the given {@code sourceUnit}
* @param unit
*/
public void delay(final long duration, final TimeUnit unit) {
long currentTime = System.currentTimeMillis();
long deadline = currentTime+unit.toMillis(duration);
ReentrantLock lock = new ReentrantLock();
Condition waitCondition = lock.newCondition();
while ((deadline-currentTime)>0) {
try {
lock.lockInterruptibly();
waitCondition.await(deadline-currentTime, TimeUnit.MILLISECONDS);
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
return;
} finally {
lock.unlock();
}
currentTime = System.currentTimeMillis();
}
}
}
To get the length of a string stored in a variable, say:
myvar="some string"
size=${#myvar}
To confirm it was properly saved, echo

trunc(tran_date) = trunc(sysdate -1)
I guess to use the external sdcard you need to use this:
new File("/mnt/external_sd/")
OR
new File("/mnt/extSdCard/")
in your case...
in replace of Environment.getExternalStorageDirectory()
Works for me. You should check whats in the directory mnt first and work from there..
You should use some type of selection method to choose which sdcard to use:
File storageDir = new File("/mnt/");
if(storageDir.isDirectory()){
String[] dirList = storageDir.list();
//TODO some type of selecton method?
}
Here is my simple solution:
If you have python2 and python3 both installed in your system, the pip upgrade will point to python2 by default. Hence, we must specify the version of python(python3) and use the below command:
python3 -m pip install --upgrade pip
This command will uninstall the previously installed pip and install the new version- upgrading your pip.
This will save memory and declutter your system.
I would use shift() function as follows:
df['value_1'] = df.value.shift(-1)
[print(x) for x in df.T.unstack().dropna(how = 'any').values];
which produces
AA
BB
BB
CC
CC
This is how the code above works:
Step 1) Use shift function
df['value_1'] = df.value.shift(-1)
print(df)
produces
value value_1
0 AA BB
1 BB CC
2 CC NaN
step 2) Transpose:
df = df.T
print(df)
produces:
0 1 2
value AA BB CC
value_1 BB CC NaN
Step 3) Unstack:
df = df.unstack()
print(df)
produces:
0 value AA
value_1 BB
1 value BB
value_1 CC
2 value CC
value_1 NaN
dtype: object
Step 4) Drop NaN values
df = df.dropna(how = 'any')
print(df)
produces:
0 value AA
value_1 BB
1 value BB
value_1 CC
2 value CC
dtype: object
Step 5) Return a Numpy representation of the DataFrame, and print value by value:
df = df.values
[print(x) for x in df];
produces:
AA
BB
BB
CC
CC
I was having the same problem and even though I was styling my button in CSS it would never pick up the border:none
but what worked was adding a style directly on the input button like so:
<div style="text-align:center;">
<input type="submit" class="SubmitButtonClass" style="border:none;" value="" />
</div>
I needed something for longpress keyboard events, so I wrote this.
var longpressKeys = [13];
var longpressTimeout = 1500;
var longpressActive = false;
var longpressFunc = null;
document.addEventListener('keydown', function(e) {
if (longpressFunc == null && longpressKeys.indexOf(e.keyCode) > -1) {
longpressFunc = setTimeout(function() {
console.log('longpress triggered');
longpressActive = true;
}, longpressTimeout);
// any key not defined as a longpress
} else if (longpressKeys.indexOf(e.keyCode) == -1) {
console.log('shortpress triggered');
}
});
document.addEventListener('keyup', function(e) {
clearTimeout(longpressFunc);
longpressFunc = null;
// longpress key triggered as a shortpress
if (!longpressActive && longpressKeys.indexOf(e.keyCode) > -1) {
console.log('shortpress triggered');
}
longpressActive = false;
});
You must type in the same name in your select query as your entity or class(case sensitive) . i.e. select user from className/Entity Name user;
It sort of depends on what you mean by "convert".
If you have a series of characters that represents an integer, like "123456", then there are two typical ways to do that in C: Use a special-purpose conversion like atoi() or strtol(), or the general-purpose sscanf(). C++ (which is really a different language masquerading as an upgrade) adds a third, stringstreams.
If you mean you want the exact bit pattern in one of your int
variables to be treated as a char
, that's easier. In C the different integer types are really more of a state of mind than actual separate "types". Just start using it where char
s are asked for, and you should be OK. You might need an explicit conversion to make the compiler quit whining on occasion, but all that should do is drop any extra bits past 256.
The following code can help you to understand some real world use of predicates (Combined with named iterators).
namespace Predicate
{
class Person
{
public int Age { get; set; }
}
class Program
{
static void Main(string[] args)
{
foreach (Person person in OlderThan(18))
{
Console.WriteLine(person.Age);
}
}
static IEnumerable<Person> OlderThan(int age)
{
Predicate<Person> isOld = x => x.Age > age;
Person[] persons = { new Person { Age = 10 }, new Person { Age = 20 }, new Person { Age = 19 } };
foreach (Person person in persons)
if (isOld(person)) yield return person;
}
}
}
When you use a CASE
expression (not statement) you have to be aware of data type precedence. In this case you can't just set a DATETIME
to an empty string. Try it:
SELECT CONVERT(DATETIME, '');
One workaround is to present your date as a string:
CASE WHEN CONVERT(DATE, CreatedDate) = '1900-01-01' -- to account for accidental time
THEN ''
ELSE CONVERT(CHAR(10), CreatedDate, 120)
+ ' ' + CONVERT(CHAR(8), CreatedDate, 108)
END
Or you could fiddle with the presentation stuff where it belongs, at the presentation tier.
Here is an example that works exactly as you seem to want:
DECLARE @d TABLE(CreatedDate DATETIME);
INSERT @d SELECT '19000101' UNION ALL SELECT '20130321';
SELECT d = CASE WHEN CreatedDate = '19000101'
THEN ''
ELSE CONVERT(CHAR(10), CreatedDate, 120)
+ ' ' + CONVERT(CHAR(8), CreatedDate, 108)
END FROM @d;
Results:
d
-------------------
<-- empty string

The big problem with this exception is that its usually not reproducible in a test environment and we are not around to run innodb engine status when it happens on prod. So in one of the projects I put the below code into a catch block for this exception. That helped me catch the engine status when the exception happened. That helped a lot.
Statement st = con.createStatement();
ResultSet rs = st.executeQuery("SHOW ENGINE INNODB STATUS");
while(rs.next()){
log.info(rs.getString(1));
log.info(rs.getString(2));
log.info(rs.getString(3));
}
To compare entire revisions, it's simply:
svn diff -r 8979:11390
If you want to compare the last committed state against your currently saved working files, you can use convenience keywords:
svn diff -r PREV:HEAD
(Note, without anything specified afterwards, all files in the specified revisions are compared.)
You can compare a specific file if you add the file path afterwards:
svn diff -r 8979:HEAD /path/to/my/file.php
You may be able to achieve what you want with Class Table Inheritance where you change AlbumTrackReference to AlbumTrack:
class AlbumTrack extends Track { /* ... */ }
And getTrackList()
would contain AlbumTrack
objects which you could then use like you want:
foreach($album->getTrackList() as $albumTrack)
{
echo sprintf("\t#%d - %-20s (%s) %s\n",
$albumTrack->getPosition(),
$albumTrack->getTitle(),
$albumTrack->getDuration()->format('H:i:s'),
$albumTrack->isPromoted() ? ' - PROMOTED!' : ''
);
}
You will need to examine this throughly to ensure you don't suffer performance-wise.
Your current set-up is simple, efficient, and easy to understand even if some of the semantics don't quite sit right with you.
I don't know if the answer will be late, but I have used this form.

Try to create a new database and import every table, query etc into this new database. With this import Access recreates all the objects from scratch. If there is some sort of corruption in an object, it should be solved.
If you're Lucky only the corrupted item(s) will be lost, if any.
This works perfectly:
for /f "usebackq tokens=2,*" %A in (`reg query HKCU\Environment /v PATH`) do set my_user_path=%B
setx PATH "C:\Python27;C:\Python27\Scripts;%my_user_path%"
The 1st command gets the USER environment variable 'PATH', into 'my_user_path' variable The 2nd line prepends the 'C:\Python27;C:\Python27\Scripts;' to the USER environment variable 'PATH'
I am totally unable to connect to localdb with any tool including MSSMA, sqlcmd, etc. You would think Microsoft would document this, but I find nothing on MSDN. I have v12 and tried (localdb)\v12.0
and that didn't work. Issuing the command sqllocaldb i MSSQLLocalDB
shows that the local instance is running, but there is no way to connect to it.
c:\> sqllocaldb i MSSQLLocalDB
Name: MSSQLLocalDB
Version: 12.0.2000.8
Shared name:
Owner: CWOLF-PC\cwolf
Auto-create: Yes
State: Running
Last start time: 6/12/2014 8:34:11 AM
Instance pipe name: np:\\.\pipe\LOCALDB#C86052DD\tsql\query
c:\>
c:\> sqlcmd -L
Servers:
;UID:Login ID=?;PWD:Password=?;Trusted_Connection:Use Integrated Security=?;
*APP:AppName=?;*WSID:WorkStation ID=?;
I finally figured it out!! the connect string is (localdb)\MSSQLLocalDB
, e.g.:
$ sqlcmd -S \(localdb\)\\MSSQLLocalDB
1> select 'hello!'
2> go
------
hello!

Another solution cold be:
$value = $arr[count($arr) - 1];
The above will count the amount of array values, substract 1 and then return the value.
Note: This can only be used if your array keys are numeric.
If you need a specific exit status, Ansible provides a way to do that via callback plugins.
Example. It's a very good option if you need a 100% accurate exit status.
If not, you can always use the Debug Module, which is the standard for this cases of use.

You will need to melt
your dataframe to get it into the so-called long format:
require(reshape2)
sample.data.M <- melt(sample.data)
Now your field values are represented by their own rows and identified through the variable column. This can now be leveraged within the ggplot aesthetics:
require(ggplot2)
c <- ggplot(sample.data.M, aes(x = Rank, y = value, fill = variable))
c + geom_bar(stat = "identity")
Instead of stacking you may also be interested in showing multiple plots using facets:
c <- ggplot(sample.data.M, aes(x = Rank, y = value))
c + facet_wrap(~ variable) + geom_bar(stat = "identity")
I would do it the following way:
>>> x = np.array([[1,0,0], [0,2,0], [1,1,0]])
>>> x
array([[1, 0, 0],
[0, 2, 0],
[1, 1, 0]])
>>> np.nonzero(x)
(array([0, 1, 2, 2]), array([0, 1, 0, 1]))
# if you want it in coordinates
>>> x[np.nonzero(x)]
array([1, 2, 1, 1])
>>> np.transpose(np.nonzero(x))
array([[0, 0],
[1, 1],
[2, 0],
[2, 1])
Use the following instead:
boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );
This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.
Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.
Do you have _timestamp enabled in your doc mapping?
{
"doctype": {
"_timestamp": {
"enabled": "true",
"store": "yes"
},
"properties": {
...
}
}
}
You can check your mapping here:
http://localhost:9200/_all/_mapping
If so I think this might work to get most recent:
{
"query": {
"match_all": {}
},
"size": 1,
"sort": [
{
"_timestamp": {
"order": "desc"
}
}
]
}

Allow from all
</Directory>
</VirtualHost>
To:
<VirtualHost *:80>

100% working Concept to send email with attachment in php :
if (isset($_POST['submit'])) {
extract($_POST);
require_once('mail/class.phpmailer.php');
$subject = "$name Applied For - $position";
$email_message = "<div>Thanks for Applying ....</div> ";
$mail = new PHPMailer;
$mail->IsSMTP(); // telling the class to use SMTP
$mail->Host = "mail.companyname.com"; // SMTP server
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->SMTPSecure = "ssl";
$mail->Host = "smtp.gmail.com";
$mail->Port = 465;
$mail->IsHTML(true);
$mail->Username = "[email protected]"; // GMAIL username
$mail->Password = "mailPassword"; // GMAIL password
$mail->SetFrom('[email protected]', 'new application submitted');
$mail->AddReplyTo("[email protected]","First Last");
$mail->Subject = "your subject";
$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
$mail->MsgHTML($email_message);
$address = '[email protected]';
$mail->AddAddress($address, "companyname");
$mail->AddAttachment($_FILES['file']['tmp_name'], $_FILES['file']['name']); // attachment
if (!$mail->Send()) {
/* Error */
echo 'Message not Sent! Email at [email protected]';
} else {
/* Success */
echo 'Sent Successfully! <b> Check your Mail</b>';
}
}
I used this code for google smtp mail sending with Attachment....

The issue here that the Python version used to build your Lambda function dependencies (on your own machine) is different than the selected Python version for your Lambda function. This case is common especially if the Numpy library part of your dependencies.
Example: Your machine's python version: 3.6 ---> Lambda python version 3.6
you just need to import this
import org.json.JSONObject;
constructing the String that you want to send
JSONObject param=new JSONObject();
JSONObject post=new JSONObject();
im using two object because you can have an jsonObject within another
post.put("username(here i write the key)","someusername"(here i put the value);
post.put("message","this is a sweet message");
post.put("image","http://localhost/someimage.jpg");
post.put("time": "present time");
then i put the post json inside another like this
param.put("post",post);
this is the method that i use to make a request
makeRequest(param.toString());
public JSONObject makeRequest(String param)
{
try
{
setting the connection
urlConnection = new URL("your url");
connection = (HttpURLConnection) urlConnection.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-type", "application/json;charset=UTF-8");
connection.setReadTimeout(60000);
connection.setConnectTimeout(60000);
connection.connect();
setting the outputstream
dataOutputStream = new DataOutputStream(connection.getOutputStream());
i use this to see in the logcat what i am sending
Log.d("OUTPUT STREAM " ,param);
dataOutputStream.writeBytes(param);
dataOutputStream.flush();
dataOutputStream.close();
InputStream in = new BufferedInputStream(connection.getInputStream());
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
result = new StringBuilder();
String line;
here the string is constructed
while ((line = reader.readLine()) != null)
{
result.append(line);
}
i use this log to see what its comming in the response
Log.d("INPUTSTREAM: ",result.toString());
instancing a json with the String that contains the server response
jResponse=new JSONObject(result.toString());
}
catch (IOException e) {
e.printStackTrace();
return jResponse=null;
} catch (JSONException e)
{
e.printStackTrace();
return jResponse=null;
}
connection.disconnect();
return jResponse;
}
You need to send this
object only instead of this.value
while calling onchange
<input type='file' id="upload" onchange="readURL(this)" />
because you are using input
variable as this
in your function, like at line
var url = input.value;// reading value property of input element
EDIT - Try using jQuery like below --
remove onchange from input field :
<input type='file' id="upload" >
Bind onchange
event to input field :
$(function(){
$('#upload').change(function(){
var input = this;
var url = $(this).val();
var ext = url.substring(url.lastIndexOf('.') + 1).toLowerCase();
if (input.files && input.files[0]&& (ext == "gif" || ext == "png" || ext == "jpeg" || ext == "jpg"))
{
var reader = new FileReader();
reader.onload = function (e) {
$('#img').attr('src', e.target.result);
}
reader.readAsDataURL(input.files[0]);
}
else
{
$('#img').attr('src', '/assets/no_preview.png');
}
});
});

DateTime.parse(date).strftime("%d.%m.%y")
#=> 01.07.16
DateTime.parse(date).strftime("%A, %d %b %Y %l:%M %p")
#=> Friday, 01 Jul 2016 9:17 AM
Use this instead:
<input id='tea-submit' type='submit' name = 'submit' value = 'Tea'>
<input id='coffee-submit' type='submit' name = 'submit' value = 'Coffee'>
You can do it by walking the stack backwards. In reality, though, it's frequently easier to add an identifier onto a call stack at the beginning of each function and pop it at the end, then just walk that printing the contents. It's a bit of a PITA, but it works well and will save you time in the end.

Follow up to Eonil's answer related to project level settings. With the target selected and the Build Settings tab selected, there may be no listing under Search Paths for Header Search Paths. In this case, you can change to "All" from "Basic" in the search bar and Header Search Paths will show up in the Search Paths section.

Using this and your solution, you can handle all browsers except Firefox, which at this point I think still requires a javascript solution.
private static String readAll(Reader rd) throws IOException {
StringBuilder sb = new StringBuilder();
int cp;
while ((cp = rd.read()) != -1) {
sb.append((char) cp);
}
return sb.toString();
}
String jsonText = readAll(inputofyourjsonstream);
JSONObject json = new JSONObject(jsonText);
JSONArray arr = json.getJSONArray("sources");
Your arr would looks like: [ { "id":1001, "name":"jhon" }, { "id":1002, "name":"jhon" } ] You can use:
arr.getJSONObject(index)
to get the objects inside of the array.
it is wrong. correct will be
P3 P2 P4 P5 P1 0 3 4 6 10 as the correct difference are these
Waiting Time (0+3+4+6+10)/5 = 4.6
