Basically, you want to loop through each direct descendent of the old-parent node, and move it to the new parent. Any children of a direct descendent will get moved with it.
var newParent = document.getElementById('new-parent');
var oldParent = document.getElementById('old-parent');
while (oldParent.childNodes.length > 0) {
newParent.appendChild(oldParent.childNodes[0]);
}
I would suggest to watch model value and update it upon chage: http://plnkr.co/edit/Mb0uRyIIv1eK8nTg3Qng?p=preview
The only interesting issue is with spaces: In AngularJS 1.0.3 ng-model on input automatically trims string, so it does not detect that model was changed if you add spaces at the end or at start (so spaces are not automatically removed by my code). But in 1.1.1 there is 'ng-trim' directive that allows to disable this functionality (commit). So I've decided to use 1.1.1 to achieve exact functionality you described in your question.
In YUI, if you include yuidom, you can use
YAHOO.util.Dom.addClass('div1','className');
HTH
You can use .empty() function to clear all the child elements
$(document).ready(function () {
$("#button").click(function () {
//only the content inside of the element will be deleted
$("#masterdiv").empty();
});
});

Wouldn't it be better to not use any dynamic types for this, and let your class implement an interface. Then, you can check at runtime wether an object implements that interface, and thus, has the expected method (or property).
public interface IMyInterface
{
void Somemethod();
}
IMyInterface x = anyObject as IMyInterface;
if( x != null )
{
x.Somemethod();
}
I think this is the only correct way.
The thing you're referring to is duck-typing, which is useful in scenarios where you already know that the object has the method, but the compiler cannot check for that. This is useful in COM interop scenarios for instance. (check this article)
If you want to combine duck-typing with reflection for instance, then I think you're missing the goal of duck-typing.
This is a very important question and the answer is very simple, but fundamental:
docker run IMAGE_ID
and not docker run CONTAINER_ID
docker stop CONTAINER_ID
, you can relaunch the same container with the command docker start CONTAINER_ID
, and the data and settings will be the same.I started this gist a year ago: https://gist.github.com/PascalPrecht/5411171
Brian Ford (member of the core team) has written this blog post about it: http://briantford.com/blog/angular-bower
And then we started with this component spec (which is not quite complete): https://github.com/angular/angular-component-spec
Since the last ng-conf there's this document for best practices by the core team: https://docs.google.com/document/d/1XXMvReO8-Awi1EZXAXS4PzDzdNvV6pGcuaF4Q9821Es/pub
If you are running your script at linux environment you can use this command:
bsub -q server_name -R "rusage[mem=requested_memory]" "Rscript script_name.R"
and the server will allocate the requested memory for you (according to the server limits, but with good server - hugefiles can be used)
if you are using SQL Server use convert
e.g. select convert(varchar(10), DeliveryDate, 103) as ShortDate

To use foreach
would require you have an array that contains every row from the query result. Some DB libraries for PHP provide a fetch_all
function that provides an appropriate array but I could not find one for mysql
(however the mysqli extension does) . You could of course write your own, like so
function mysql_fetch_all($result) {
$rows = array();
while ($row = mysql_fetch_array($result)) {
$rows[] = $row;
}
return $rows;
}
However I must echo the "why?" Using this function you are creating two loops instead of one, and requring the entire result set be loaded in to memory. For sufficiently large result sets, this could become a serious performance drag. And for what?
foreach (mysql_fetch_all($result) as $row)
vs
while ($row = mysql_fetch_array($result))
while
is just as concise and IMO more readable.
EDIT There is another option, but it is pretty absurd. You could use the Iterator Interface
class MysqlResult implements Iterator {
private $rownum = 0;
private $numrows = 0;
private $result;
public function __construct($result) {
$this->result = $result;
$this->numrows = mysql_num_rows($result);
}
public function rewind() {
$this->rownum = 0;
}
public function current() {
mysql_data_seek($this->result, $this->rownum);
return mysql_fetch_array($this->result);
}
public function key() {
return $this->rownum;
}
public function next() {
$this->rownum++;
}
public function valid() {
return $this->rownum < $this->numrows ? true : false;
}
}
$rows = new MysqlResult(mysql_query($query_select));
foreach ($rows as $row) {
//code...
}
In this case, the MysqlResult
instance fetches rows only on request just like with while
, but wraps it in a nice foreach-able package. While you've saved yourself a loop, you've added the overhead of class instantiation and a boat load of function calls, not to mention a good deal of added code complexity.
But you asked if it could be done without using while
(or for
I imagine). Well it can be done, just like that. Whether it should be done is up to you.
It also counts the days and convert them in months.
function monthDiff(d1, d2) {
var months;
months = (d2.getFullYear() - d1.getFullYear()) * 12; //calculates months between two years
months -= d1.getMonth() + 1;
months += d2.getMonth(); //calculates number of complete months between two months
day1 = 30-d1.getDate();
day2 = day1 + d2.getDate();
months += parseInt(day2/30); //calculates no of complete months lie between two dates
return months <= 0 ? 0 : months;
}
monthDiff(
new Date(2017, 8, 8), // Aug 8th, 2017 (d1)
new Date(2017, 12, 12) // Dec 12th, 2017 (d2)
);
//return value will be 4 months
http://fiji.sc/Uber-JAR provides an excellent explanation of the alternatives:
There are three common methods for constructing an uber-JAR:
- Unshaded. Unpack all JAR files, then repack them into a single JAR.
- Pro: Works with Java's default class loader.
- Con: Files present in multiple JAR files with the same path (e.g., META-INF/services/javax.script.ScriptEngineFactory) will overwrite one another, resulting in faulty behavior.
- Tools: Maven Assembly Plugin, Classworlds Uberjar
- Shaded. Same as unshaded, but rename (i.e., "shade") all packages of all dependencies.
- Pro: Works with Java's default class loader. Avoids some (not all) dependency version clashes.
- Con: Files present in multiple JAR files with the same path (e.g., META-INF/services/javax.script.ScriptEngineFactory) will overwrite one another, resulting in faulty behavior.
- Tools: Maven Shade Plugin
- JAR of JARs. The final JAR file contains the other JAR files embedded within.
- Pro: Avoids dependency version clashes. All resource files are preserved.
- Con: Needs to bundle a special "bootstrap" classloader to enable Java to load classes from the wrapped JAR files. Debugging class loader issues becomes more complex.
- Tools: Eclipse JAR File Exporter, One-JAR.

data_.push_back(val);
return *this;

And use it like this:

From all of the above, I came up with this version. This version also works for me in the mac recovery terminal.
find ./ -name '*.xsl' -exec cp -prv '{}' '/path/to/targetDir/' ';'
It will look in the current directory and recursively in all of the sub directories for files with the xsl extension. It will copy them all to the target directory.
cp flags are:
The question is why does the limitation still exist. Surely modern Windows can increase the side of MAX_PATH
to allow longer paths. Why has the limitation not been removed?
Through API contract, Windows has guaranteed all applications that the standard file APIs will never return a path longer than 260
characters.
Consider the following correct code:
WIN32_FIND_DATA findData;
FindFirstFile("C:\Contoso\*", ref findData);
Windows guaranteed my program that it would populate my WIN32_FIND_DATA
structure:
WIN32_FIND_DATA {
DWORD dwFileAttributes;
FILETIME ftCreationTime;
FILETIME ftLastAccessTime;
FILETIME ftLastWriteTime;
//...
TCHAR cFileName[MAX_PATH];
//..
}
My application didn't declare the value of the constant MAX_PATH
, the Windows API did. My application used that defined value.
My structure is correctly defined, and only allocates 592
bytes total. That means that i am only able to receive a filename that is less than 260
characters. Windows promised me that if i wrote my application correctly, my application would continue to work in the future.
If Windows were to allow filenames longer than 260
characters then my existing application (which used the correct API correctly) would fail.
For anyone calling for Microsoft to change the MAX_PATH
constant, they first need to ensure that no existing application fails. For example, i still own and use a Windows application that was written to run on Windows 3.11. It still runs on 64-bit Windows 10. That is what backwards compatibility gets you.
Microsoft did create a way to use the full 32,768 path names; but they had to create a new API contract to do it. For one, you should use the Shell API to enumerate files (as not all files exist on a hard drive or network share).
But they also have to not break existing user applications. The vast majority of applications do not use the shell api for file work. Everyone just calls FindFirstFile
/FindNextFile
and calls it a day.
None of the suggested solutions worked for me when cloning a repository via ssh
. However, I was able to clone using https
, then later changed the remote to ssh
via:
git remote set-url origin [email protected]:USERNAME/REPOSITORY.git
I got this error when I tried to call a method which did not exist. It only existed in a newer version of our webservice.
JSX:
<select value={ this.state.foo } onChange={this.handleFooChange}>
<option value="A">A</option>
<option value="B">B</option>
</select>
TypeScript:
private handleFooChange = (event: React.FormEvent<HTMLSelectElement>) => {
const element = event.target as HTMLSelectElement;
this.setState({ foo: element.value });
}
This fixed it for me:
$ sudo chmod -R 755 /usr/local/share/zsh/site-functions
Credit: a post on zsh mailing list
EDIT: As pointed out by @biocyberman in the comments. You may need to update the owner of site-functions
as well:
$ sudo chown -R root:root /usr/local/share/zsh/site-functions
On my machine (OSX 10.9), I do not need to do this but YMMV.
EDIT2: On OSX 10.11, only this worked:
$ sudo chmod -R 755 /usr/local/share/zsh
$ sudo chown -R root:staff /usr/local/share/zsh
Also user:staff is the correct default permission on OSX.
The lingo in excel is different, you don't "declare variables", you "name" cells or arrays.
A good overview of how you do that is below: http://office.microsoft.com/en-001/excel-help/define-and-use-names-in-formulas-HA010342417.aspx
To pass multiple headers in a curl request you simply add additional -H
or --header
to your curl command.
Example
//Simplified
$ curl -v -H 'header1:val' -H 'header2:val' URL
//Explanatory
$ curl -v -H 'Connection: keep-alive' -H 'Content-Type: application/json' https://www.example.com
Going Further
For standard HTTP header fields such as User-Agent, Cookie, Host, there is actually another way to setting them. The curl command offers designated options for setting these header fields:
For example, the following two commands are equivalent. Both of them change "User-Agent" string in the HTTP header.
$ curl -v -H "Content-Type: application/json" -H "User-Agent: UserAgentString" https://www.example.com
$ curl -v -H "Content-Type: application/json" -A "UserAgentString" https://www.example.com
I found the best solution if you have nested numpy arrays in a dictionary:
import json
import numpy as np
class NumpyEncoder(json.JSONEncoder):
""" Special json encoder for numpy types """
def default(self, obj):
if isinstance(obj, np.integer):
return int(obj)
elif isinstance(obj, np.floating):
return float(obj)
elif isinstance(obj, np.ndarray):
return obj.tolist()
return json.JSONEncoder.default(self, obj)
dumped = json.dumps(data, cls=NumpyEncoder)
with open(path, 'w') as f:
json.dump(dumped, f)
Thanks to this guy.
Use the string constructor which accepts chararray as argument, start position and length of array. Syntax is given below:
string charToString = new string(CharArray, 0, CharArray.Count());
You can't. "" is the literal for a string, which contains no characters. It does not contain the "empty character" (whatever you mean by that).
eval('(' + jsonObject + ')')

Probably you haven't injected $http
service to your controller. There are several ways of doing that.
Please read this reference about DI. Then it gets very simple:
function MyController($scope, $http) {
// ... your code
}
Python lists have the index()
method, which you can use to find the position of the first occurrence of an item in a list. Note that list.index()
raises ValueError
when the item is not present in the list, so you may need to wrap it in try
/except
:
try:
idx = lst.index(value)
except ValueError:
idx = None
To find the position of the last occurrence of an item in a list efficiently (i.e. without creating a reversed intermediate list) you can use this function:
def rindex(lst, value):
for i, v in enumerate(reversed(lst)):
if v == value:
return len(lst) - i - 1 # return the index in the original list
return None
print(rindex([1, 2, 3], 3)) # 2
print(rindex([3, 2, 1, 3], 3)) # 3
print(rindex([3, 2, 1, 3], 4)) # None
You need to explicitly ask for the content type.
Add this line:
request.ContentType = "application/json; charset=utf-8";
At the appropriate place
var column1RelArray = [];
$('#column1 li').each(function(){
column1RelArray.push($(this).attr('rel'));
});
or fp style
var column1RelArray = $('#column1 li').map(function(){
return $(this).attr('rel');
});
With permission:
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:9875432100"));
if (ActivityCompat.checkSelfPermission(yourActivity.this,android.Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(yourActivity.this,
android.Manifest.permission.CALL_PHONE)) {
} else {
ActivityCompat.requestPermissions(yourActivity.this,
new String[]{android.Manifest.permission.CALL_PHONE},
MY_PERMISSIONS_REQUEST_CALL_PHONE);
}
}
startActivity(callIntent);
This is something I use:
$cryptoStrong = true; // can be false
$length = 16; // Any length you want
$bytes = openssl_random_pseudo_bytes($length, $cryptoStrong);
$randomString = bin2hex($bytes);
You can see the Docs for openssl_random_pseudo_bytes here, and the Docs for bin2hex here
Intent intent = new Intent(activity1.this, activity2.class);
intent.putExtra("message", message);
startActivity(intent);
In activity2, in onCreate(), you can get the String message by retrieving a Bundle (which contains all the messages sent by the calling activity) and call getString() on it :
Bundle bundle = getIntent().getExtras();
String message = bundle.getString("message");
From a lambda, you can't get a reference to anything that isn't final. You need to declare a final wrapper from outside the lamda to hold your variable.
I've added the final 'reference' object as this wrapper.
private TimeZone extractCalendarTimeZoneComponent(Calendar cal,TimeZone calTz) {
final AtomicReference<TimeZone> reference = new AtomicReference<>();
try {
cal.getComponents().getComponents("VTIMEZONE").forEach(component->{
VTimeZone v = (VTimeZone) component;
v.getTimeZoneId();
if(reference.get()==null) {
reference.set(TimeZone.getTimeZone(v.getTimeZoneId().getValue()));
}
});
} catch (Exception e) {
//log.warn("Unable to determine ical timezone", e);
}
return reference.get();
}
In my case, this code saved my day:
public static void selectSpinnerItemByValue(Spinner spnr, long value) {
SpinnerAdapter adapter = spnr.getAdapter();
for (int position = 0; position < adapter.getCount(); position++) {
if(adapter.getItemId(position) == value) {
spnr.setSelection(position);
return;
}
}
}
Inside Activity.onCreate() callback or in the another place where you need to change title:
getSupportActionBar().setTitle("Whatever title");
The lookup module of ansible works fine for me. The yml is:
- hosts: test
vars:
time: "{{ lookup('pipe', 'date -d \"1 day ago\" +\"%Y%m%d\"') }}"
You can replace any command with date to get result of the command.
I assume you are meaning "internally" within your application.
you can create your own <a>
tag and insert a url in the href like this
<a href="<?php echo site_url('controller/function/uri') ?>">Link</a>
OR you can use the URL helper this way to generate an <a>
tag
anchor(uri segments, text, attributes)
So... to use it...
<?php echo anchor('controller/function/uri', 'Link', 'class="link-class"') ?>
and that will generate
<a href="http://domain.com/index.php/controller/function/uri" class="link-class">Link</a>
For the additional commented question
I would use my first example
so...
<a href="<?php echo site_url('controller/function') ?>"><img src="<?php echo base_url() ?>img/path/file.jpg" /></a>
for images (and other assets) I wouldn't put the file path within the php, I would just echo the base_url() and then add the path normally.

My answer would be 'pick one and learn how to use it'. They're both decent shells; bash probably has more bells and whistles, but they both have the basic features you'll want. bash is more universally available these days. If you're using Linux all the time, just stick with it.
If you're programming, trying to stick to plain 'sh' for portability is good practice, but then with bash available so widely these days that bit of advice is probably a bit old-fashioned.
Learn how to use completion and your shell history; read the manpage occasionally and try to learn a few new things.
Can the screenshot or icon be transformed (scaled, rotated, skewed ...)? There are quite a few methods on top of my head that could possibly help you:
Most of these are already implemented in OpenCV - see for example the cvMatchTemplate method (uses histogram matching): http://dasl.mem.drexel.edu/~noahKuntz/openCVTut6.html. The salient point/area detectors are also available - see OpenCV Feature Detection.
Just a concrete point of measure: many years back, I benchmarked two versions of my hashing algorithm:
unsigned
hash( char const* s )
{
unsigned h = 0;
while ( *s != '\0' ) {
h = 127 * h + (unsigned char)*s;
++ s;
}
return h;
}
and
unsigned
hash( char const* s )
{
unsigned h = 0;
while ( *s != '\0' ) {
h = (h << 7) - h + (unsigned char)*s;
++ s;
}
return h;
}
On every machine I benchmarked it on, the first was at least as fast as the second. Somewhat surprisingly, it was sometimes faster (e.g. on a Sun Sparc). When the hardware didn't support fast multiplication (and most didn't back then), the compiler would convert the multiplication into the appropriate combinations of shifts and add/sub. And because it knew the final goal, it could sometimes do so in less instructions than when you explicitly wrote the shifts and the add/subs.
Note that this was something like 15 years ago. Hopefully, compilers
have only gotten better since then, so you can pretty much count on the
compiler doing the right thing, probably better than you could. (Also,
the reason the code looks so C'ish is because it was over 15 years ago.
I'd obviously use std::string
and iterators today.)
That's also my last problem. Here my solution I use data Model and adapter for my RecyclerView
/*Firstly, register your new data to your model*/
DataModel detail = new DataModel(id, name, sat, image);
/*after that, use set to replace old value with the new one*/
int index = 4;
mData.set(index, detail);
/*finally, refresh your adapter*/
if(adapter!=null)
adapter.notifyItemChanged(index);
In android gradle 0.4.0 you can just do:

If your data is in a Pandas DataFrame, you can use Seaborn's heatmap
function to create your desired plot.
import seaborn as sns
Var_Corr = df.corr()
# plot the heatmap and annotation on it
sns.heatmap(Var_Corr, xticklabels=Var_Corr.columns, yticklabels=Var_Corr.columns, annot=True)
From the question, it looks like the data is in a NumPy array. If that array has the name numpy_data
, before you can use the step above, you would want to put it into a Pandas DataFrame using the following:
import pandas as pd
df = pd.DataFrame(numpy_data)
It's possible but no heap allocation allowed directly. Heap allocation is performed at runtime. Here are a few examples:
static SOME_INT: i32 = 5;
static SOME_STR: &'static str = "A static string";
static SOME_STRUCT: MyStruct = MyStruct {
number: 10,
string: "Some string",
};
static mut db: Option<sqlite::Connection> = None;
fn main() {
println!("{}", SOME_INT);
println!("{}", SOME_STR);
println!("{}", SOME_STRUCT.number);
println!("{}", SOME_STRUCT.string);
unsafe {
db = Some(open_database());
}
}
struct MyStruct {
number: i32,
string: &'static str,
}
Try this, it's working for me.
Sender:
byte[] message = ...
Socket socket = ...
DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());
dOut.writeInt(message.length); // write length of the message
dOut.write(message); // write the message
Receiver:
Socket socket = ...
DataInputStream dIn = new DataInputStream(socket.getInputStream());
int length = dIn.readInt(); // read length of incoming message
if(length>0) {
byte[] message = new byte[length];
dIn.readFully(message, 0, message.length); // read the message
}

Just run below images:
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock nate/dockviz images -t
In a nutshell, sys.argv
is a list of the words that appear in the command used to run the program. The first word (first element of the list) is the name of the program, and the rest of the elements of the list are any arguments provided. In most computer languages (including Python), lists are indexed from zero, meaning that the first element in the list (in this case, the program name) is sys.argv[0]
, and the second element (first argument, if there is one) is sys.argv[1]
, etc.
The test len(sys.argv) >= 2
simply checks wither the list has a length greater than or equal to 2, which will be the case if there was at least one argument provided to the program.
You need to print the result of the getText()
. You're currently printing the object TxtBoxContent
.
getText()
will only get the inner text of an element. To get the value, you need to use getAttribute()
.
WebElement TxtBoxContent = driver.findElement(By.id(WebelementID));
System.out.println("Printing " + TxtBoxContent.getAttribute("value"));
It can be done using inner query Like this
$query = "SELECT *
FROM (SELECT Category
FROM currency_rates
ORDER BY id DESC) as rows
GROUP BY currency";
Most updated way to achieve this is:
Add this to your EditText in XML:
android:imeOptions="actionSearch"
Then in your Activity/Fragment:
EditText.setOnEditorActionListener { _, actionId, _ ->
if (actionId == EditorInfo.IME_ACTION_SEARCH) {
// Do what you want here
return@setOnEditorActionListener true
}
return@setOnEditorActionListener false
}
Simplified example (with counter):
With Me.lstbox
.ColumnCount = 2
.ColumnWidths = "60;60"
.AddItem
.List(i, 0) = Company_ID
.List(i, 1) = Company_name
i = i + 1
end with
Make sure to start the counter with 0, not 1 to fill up a listbox.
I believe it was already mentioned in other threads:
calc(){ awk "BEGIN { print "$*" }"; }
then you can simply type :
calc 7.5/3.2
2.34375
In your case it will be:
x=20; y=3;
calc $x/$y
or if you prefer, add this as a separate script and make it available in $PATH so you will always have it in your local shell:
#!/bin/bash
calc(){ awk "BEGIN { print $* }"; }
An array can be initialized by using the new Object {}
syntax.
For example, an array of String
can be declared by either:
String[] s = new String[] {"One", "Two", "Three"};
String[] s2 = {"One", "Two", "Three"};
Primitives can also be similarly initialized either by:
int[] i = new int[] {1, 2, 3};
int[] i2 = {1, 2, 3};
Or an array of some Object
:
Point[] p = new Point[] {new Point(1, 1), new Point(2, 2)};
All the details about arrays in Java is written out in Chapter 10: Arrays in The Java Language Specifications, Third Edition.
print date('H:i');
$var = date('H:i');

Travis-ci and Jenkins, while both are tools for continuous integration are very different.
Travis is a hosted service (free for open source) while you have to host, install and configure Jenkins.
Travis does not have jobs as in Jenkins. The commands to run to test the code are taken from a file named .travis.yml
which sits along your project code. This makes it easy to have different test code per branch since each branch can have its own version of the .travis.yml file.
You can have a similar feature with Jenkins if you use one of the following plugins:
.jervis.yml
file found at the root of project code. If .jervis.yml
does not exist, it will fall back to using .travis.yml
file instead.There are other hosted services you might also consider for continuous integration (non exhaustive list):
You might want to stay with Jenkins because you are familiar with it or don't want to depend on 3rd party for your continuous integration system. Else I would drop Jenkins and go with one of the free hosted CI services as they save you a lot of trouble (host, install, configure, prepare jobs)
Depending on where your code repository is hosted I would make the following choices:
To setup Travis-CI on a github project, all you have to do is:
The features you get are:
One clean solution is to use NumPy's outer-product function with a vector of ones:
np.outer(np.ones(n), x)
gives n
repeating rows. Switch the argument order to get repeating columns. To get an equal number of rows and columns you might do
np.outer(np.ones_like(x), x)
#Try this:
input[type="text"],textarea[type="text"]::-webkit-input-placeholder {
color:#f51;
}
input[type="text"],textarea[type="text"]:-moz-placeholder {
color:#f51;
}
input[type="text"],textarea[type="text"]::-moz-placeholder {
color:#f51;
}
input[type="text"],textarea[type="text"]:-ms-input-placeholder {
color:#f51;
}
##Works very well for me.
I store my data this way:
accountsTable ->
key1 -> account1
key2 -> account2
in order to get object data:
accountsDb = mDatabase.child("accountsTable");
accountsDb.child("some key").addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot snapshot) {
try{
Account account = snapshot.getChildren().iterator().next()
.getValue(Account.class);
} catch (Throwable e) {
MyLogger.error(this, "onCreate eror", e);
}
}
@Override public void onCancelled(DatabaseError error) { }
});
startMode="alwaysRunning" in $SOLUTION_DIR/bis/.vs/config/applicationhost.config
caused it for me. Try to remove that string and everything will work again (even without restart of VS)
To follow up on Theo's suggestion with my findings (apologies - I don't currently have enough reputation to post this as a comment)
First, this is how to use several named parameters:
String commandString = "INSERT INTO Users (Name, Desk, UpdateTime) VALUES (:Name, :Desk, :UpdateTime)";
using (OracleCommand command = new OracleCommand(commandString, _connection, _transaction))
{
command.Parameters.Add("Name", OracleType.VarChar, 50).Value = strategy;
command.Parameters.Add("Desk", OracleType.VarChar, 50).Value = deskName ?? OracleString.Null;
command.Parameters.Add("UpdateTime", OracleType.DateTime).Value = updated;
command.ExecuteNonQuery();
}
However, I saw no variation in speed between:
I'm using System.Data.OracleClient, deleting and inserting 2500 rows inside a transaction

You can find a lot of css spinners like this here : http://cssload.net/en/spinners/
update-java-alternatives -l
will tell you which java implementation is the default for your system and where in the filesystem it is installed. Check the manual for more options.
The reason you get a Null Pointer Exception is because there is no key likesZZZ in your second example. Try:
def mymap = [name:"Gromit", likes:"cheese", id:1234]
def x = mymap.find{ it.key == "likes" }.value
if(x)
println "x value: ${x}"
Open the output stream and store properties after you have closed the input stream.
FileInputStream in = new FileInputStream("First.properties");
Properties props = new Properties();
props.load(in);
in.close();
FileOutputStream out = new FileOutputStream("First.properties");
props.setProperty("country", "america");
props.store(out, null);
out.close();
I was able to find a simple way to achieve both scrolling behaviors.
Here is the xml for it:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

android:scrollbars="vertical">
<HorizontalScrollView
android:layout_width="320px" android:layout_height="fill_parent">
<TableLayout
android:id="@+id/linlay" android:layout_width="320px"
android:layout_height="fill_parent" android:stretchColumns="1"
android:background="#000000"/>
</HorizontalScrollView>
</ScrollView>
According to maven website, the last version to support Java 6 is 3.2.5, and 3.3 and up use Java 7. My hunch is that you're using Maven 3.3 or higher, and should either upgrade to Java 7 (and set proper source/target attributes in your pom) or downgrade maven.
Using answer by @Aerospace, I realized that it is legitimate for INI files to have sections without any key-values. In this case, addition to the top-level map should happen before any key-values are found, ex (minimally updated for Java 8):
Path location = ...;
try (BufferedReader br = new BufferedReader(new FileReader(location.toFile()))) {
String line;
String section = null;
while ((line = br.readLine()) != null) {
Matcher m = this.section.matcher(line);
if (m.matches()) {
section = m.group(1).trim();
entries.computeIfAbsent(section, k -> new HashMap<>());
} else if (section != null) {
m = keyValue.matcher(line);
if (m.matches()) {
String key = m.group(1).trim();
String value = m.group(2).trim();
entries.get(section).put(key, value);
}
}
}
} catch (IOException ex) {
System.err.println("Failed to read and parse INI file '" + location + "', " + ex.getMessage());
ex.printStackTrace(System.err);
}
I had the same problem. I resolved, uninstalling all de the versions in my pc and then reinstall dotnet.
So i tried the above :javascript which works :) However HAML wraps the generated code in CDATA like so:
<script type="text/javascript">
//<![CDATA[
$(document).ready( function() {
$('body').addClass( 'test' );
} );
//]]>
</script>
The following HAML will generate the typical tag for including (for example) typekit or google analytics code.
%script{:type=>"text/javascript"}
//your code goes here - dont forget the indent!
f = open('C:\\Users\\Pooja\\Desktop\\trolldata.csv')
Use '\\' for python program in Python version 3 and above.. Error will be resolved..
$(element).on("click mousedown mouseup focus blur keydown change",function(e){
console.log(e);
});
That will get you a lot (but not all) of the information on if an event is fired... other than manually coding it like this, I can't think of any other way to do that.
var foo = @"D:\Projects\Some\Kind\Of\Pathproblem\wuhoo.xml";
You could use a list comprehension or a generator expression instead:
', '.join([str(x) for x in list]) # list comprehension
', '.join(str(x) for x in list) # generator expression
For redhat linux
sudo vi /var/lib/pgsql9/data/postgresql.conf
pgsql9 is the folder for the postgres version installed, might be different for others
changed listen_addresses = '*' from listen_addresses = ‘localhost’ and then
sudo /etc/init.d/postgresql stop
sudo /etc/init.d/postgresql start

A SqlDataAdapter is typically used to fill a DataSet or DataTable and so you will have access to the data after your connection has been closed (disconnected access).
The SqlDataReader is a fast forward-only and connected cursor which tends to be generally quicker than filling a DataSet/DataTable.
Furthermore, with a SqlDataReader, you deal with your data one record at a time, and don't hold any data in memory. Obviously with a DataTable or DataSet, you do have a memory allocation overhead.
If you don't need to keep your data in memory, so for rendering stuff only, go for the SqlDataReader. If you want to deal with your data in a disconnected fashion choose the DataAdapter to fill either a DataSet or DataTable.
For me the better approach is that:
s.split('mango', 1)[-1]
...because if happens that occurrence is not in the string you'll get "IndexError: list index out of range"
.
Therefore -1
will not get any harm cause number of occurrences is already set to one.
my py version is 3.7.3, and this cmd worked
python3.7 -m pip install requests
requests library - for retrieving data from web APIs.
This runs the pip module and asks it to find the requests library on PyPI.org (the Python Package Index) and install it in your local system so that it becomes available for you to import
I think its because the two machines usually would need to be optimized in different ways. Other than that I have no idea, we run all our applications with the server-database on the same machine - granted we're not public facing - but we've had no problems.
I can't imagine that too many people care about one machine being compromised over both since the web application will usually have nearly unrestricted access to at the very least the data if not the schema inside the database.
Interested in what others might say.
Factory pattern is also used for loading beans through BeanFactory and Application context.
If you're going to be doing this search frequently, consider changing the format of your object so dinner actually is a key. This is kind of like assigning a primary clustered key in a database table. So, for example:
Obj = { 'pizza' : { 'name' : 'bob' }, 'sushi' : { 'name' : 'john' } }
You can now easily access it like this: Object['sushi']['name']
Or if the object really is this simple (just 'name' in the object), you could just change it to:
Obj = { 'pizza' : 'bob', 'sushi' : 'john' }
And then access it like: Object['sushi']
.
It's obviously not always possible or to your advantage to restructure your data object like this, but the point is, sometimes the best answer is to consider whether your data object is structured the best way. Creating a key like this can be faster and create cleaner code.
If you round 8.8333333333339 to 2 decimals, the correct answer is 8.83, not 8.84. The reason you got 8.83000000001 is because 8.83 is a number that cannot be correctly reprecented in binary, and it gives you the closest one. If you want to print it without all the zeros, do as VGE says:
print "%.2f" % 8.833333333339 #(Replace number with the variable?)
What version of SQL Server are you using? In SQL Server 2008 you can use Table Parameters and Table Types.
An alternative approach is to return a table variable from a user defined function but I am not a big fan of this method.
You can find an example here
AFAIK, you can't create a File
from an assets file because these are stored in the apk, that means there is no path to an assets folder.
But, you can try to create that File
using a buffer and the AssetManager
(it provides access to an application's raw asset files).
Try to do something like:
AssetManager am = getAssets();
InputStream inputStream = am.open("myfoldername/myfilename");
File file = createFileFromInputStream(inputStream);
private File createFileFromInputStream(InputStream inputStream) {
try{
File f = new File(my_file_name);
OutputStream outputStream = new FileOutputStream(f);
byte buffer[] = new byte[1024];
int length = 0;
while((length=inputStream.read(buffer)) > 0) {
outputStream.write(buffer,0,length);
}
outputStream.close();
inputStream.close();
return f;
}catch (IOException e) {
//Logging exception
}
return null;
}

I would strongly recommend using a library like PHPMailer to send emails.
It's easier and handles most of the issues automatically for you.
Regarding displaying embedded (inline) images, here's what's on their documentation:
Inline Attachments
There is an additional way to add an attachment. If you want to make a HTML e-mail with images incorporated into the desk, it's necessary to attach the image and then link the tag to it. For example, if you add an image as inline attachment with the CID my-photo, you would access it within the HTML e-mail with
<img src="cid:my-photo" alt="my-photo" />
.In detail, here is the function to add an inline attachment:
$mail->AddEmbeddedImage(filename, cid, name);
//By using this function with this example's value above, results in this code:
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg ');
To give you a more complete example of how it would work:
<?php
require_once('../class.phpmailer.php');
$mail = new PHPMailer(true); // the true param means it will throw exceptions on errors, which we need to catch
$mail->IsSMTP(); // telling the class to use SMTP
try {
$mail->Host = "mail.yourdomain.com"; // SMTP server
$mail->Port = 25; // set the SMTP port
$mail->SetFrom('[email protected]', 'First Last');
$mail->AddAddress('[email protected]', 'John Doe');
$mail->Subject = 'PHPMailer Test';
$mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
$mail->Body = 'Your <b>HTML</b> with an embedded Image: <img src="cid:my-attach"> Here is an image!';
$mail->AddAttachment('something.zip'); // this is a regular attachment (Not inline)
$mail->Send();
echo "Message Sent OK<p></p>\n";
} catch (phpmailerException $e) {
echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
echo $e->getMessage(); //Boring error messages from anything else!
}
?>
Regarding your comment, you asked how to send HTML email with embedded images, so I gave you an example of how to do that.
The library I told you about can send emails using a lot of methods other than SMTP.
Take a look at the PHPMailer Example page for other examples.
One way or the other, if you don't want to send the email in the ways supported by the library, you can (should) still use the library to build the message, then you send it the way you want.
For example:
You can replace the line that send the email:
$mail->Send();
With this:
$mime_message = $mail->CreateBody(); //Retrieve the message content
echo $mime_message; // Echo it to the screen or send it using whatever method you want
Hope that helps. Let me know if you run into trouble using it.
Here is my proposal for a script which returns the name of the sheet from its position in the sheet list in parameter. If no parameter is provided, the current sheet name is returned.
function sheetName(idx) {
if (!idx)
return SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getName();
else {
var sheets = SpreadsheetApp.getActiveSpreadsheet().getSheets();
var idx = parseInt(idx);
if (isNaN(idx) || idx < 1 || sheets.length < idx)
throw "Invalid parameter (it should be a number from 0 to "+sheets.length+")";
return sheets[idx-1].getName();
}
}
You can then use it in a cell like any function
=sheetName() // display current sheet name
=sheetName(1) // display first sheet name
=sheetName(5) // display 5th sheet name
As described by other answers, you need to add this code in a script with :
Tools > Script editor
var arr = [1, 2, 3, 1023, 1024];
for (var value; value = arr.pop();) {
value + 1
}

<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>
That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em'
as the measurement, you may want to use other units, like 'px'
.
EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:
In your HTML page, containing the <p>
tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:
<head>
<style type="text/css">
p { margin-left:5em; /* Or another measurement unit, like px */ }
</style>
</head>
<body>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>
So above, all <p>
elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:
<head>
<style type="text/css">
.container p { margin-left:5em; /* Or another measurement unit, like px */ }
</style>
</head>
<body>
<div class="container">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</div>
<p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>
In the example above, only the <p>
element inside the div, whose class name is 'container', will have the styles applied - and not the <p>
element outside the container.
In addition to the above, you can collect your styles together and remove the style element from the <head>
tag, replacing it with a <link>
tag, which points to an external CSS file. This external file is where you'd now put your <p>
tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.
You could use mapvalues()
from the plyr package.
Initial data:
dat <- data.frame(HouseType = c("Semi", "Single", "Row", "Single", "Apartment", "Apartment", "Row"))
> dat
HouseType
1 Semi
2 Single
3 Row
4 Single
5 Apartment
6 Apartment
7 Row
Lookup / crosswalk table:
lookup <- data.frame(type_text = c("Semi", "Single", "Row", "Apartment"), type_num = c(1, 2, 3, 4))
> lookup
type_text type_num
1 Semi 1
2 Single 2
3 Row 3
4 Apartment 4
Create the new variable:
dat$house_type_num <- plyr::mapvalues(dat$HouseType, from = lookup$type_text, to = lookup$type_num)
Or for simple replacements you can skip creating a long lookup table and do this directly in one step:
dat$house_type_num <- plyr::mapvalues(dat$HouseType,
from = c("Semi", "Single", "Row", "Apartment"),
to = c(1, 2, 3, 4))
Result:
> dat
HouseType house_type_num
1 Semi 1
2 Single 2
3 Row 3
4 Single 2
5 Apartment 4
6 Apartment 4
7 Row 3
I have finally figured out what causes this issue.
Actually, you should avoid pushing .idea/libraries
folder to your repository. It creates weird stuff in Android Studio which tends to remove all downloaded libraries.
If you have commit history, just recreate all missing library files and avoid them to be committed again. Otherwise, just remove whole .idea
folder and reimport it into AS.
I had to puzzle my way through self-signed certificates on Windows by combining bits and pieces from the given answers and further resources. Here is my own (and hopefully complete) walk-through. Hope it will spare you some of my own painful learning curve. It also contains infos on related topics that will pop up sooner or later when you create your own certs.
Don't use makecert.exe. It has been deprecated by Microsoft.
The modern way uses a Powershell command.
Windows 10:
Open Powershell with Administrator privileges:
New-SelfSignedCertificate -DnsName "*.dev.local", "dev.local", "localhost" -CertStoreLocation cert:\LocalMachine\My -FriendlyName "Dev Cert *.dev.local, dev.local, localhost" -NotAfter (Get-Date).AddYears(15)
Windows 8, Windows Server 2012 R2:
In Powershell on these systems the parameters -FriendlyName and -NotAfter do not exist. Simply remove them from the above command line.
Open Powershell with Administrator privileges:
New-SelfSignedCertificate -DnsName "*.dev.local", "dev.local", "localhost" -CertStoreLocation cert:\LocalMachine\My
An alternative is to use the method for older Windows version below, which allows you to use all the features of Win 10 for cert creation...
Older Windows versions:
My recommendation for older Windows versions is to create the cert on a Win 10 machine, export it to a .PFX file using an mmc instance (see "Trust the certificate" below) and import it into the cert store on the target machine with the old Windows OS. To import the cert do NOT right-click it. Although there is an "Import certificate" item in the context menu, it failed all my trials to use it on Win Server 2008. Instead open another mmc instance on the target machine, navigate to "Certificates (Local Computer) / Personal / Certificates", right click into the middle pane and select All tasks ? Import.
Both of the above commands create a certificate for the domains localhost
and *.dev.local
.
The Win10 version additionally has a live time of 15 years and a readable display name of "Dev Cert *.dev.local, dev.local, localhost".
Update: If you provide multiple hostname entries in parameter -DnsName
(as shown above) the first of these entries will become the domain's Subject (AKA Common Name). The complete list of all hostname entries will be stored in the field Subject Alternative Name (SAN) of the certificate. (Thanks to @BenSewards for pointing that out.)
After creation the cert will be immediately available in any HTTPS bindings of IIS (instructions below).
The new cert is not part of any chain of trust and is thus not considered trustworthy by any browsers. To change that, we will copy the cert to the certificate store for Trusted Root CAs on your machine:
Open mmc.exe, File ? Add/Remove Snap-In ? choose "Certificates" in left column ? Add ? choose "Computer Account" ? Next ? "Local Computer..." ? Finish ? OK
In the left column choose "Certificates (Local Computer) / Personal / Certificates".
Find the newly created cert (in Win 10 the column "Friendly name" may help).
Select this cert and hit Ctrl-C to copy it to clipboard.
In the left column choose "Certificates (Local Computer) / Trusted Root CAs / Certificates".
Hit Ctrl-V to paste your certificate to this store.
The certificate should appear in the list of Trusted Root Authorities and is now considered trustworthy.
Now you may go to IIS Manager, select the bindings of a local website ? Add ? https ? enter a host name of the form myname.dev.local
(your cert is only valid for *.dev.local
) and select the new certificate ? OK.
Add to hosts
Also add your host name to C:\Windows\System32\drivers\etc\hosts:
127.0.0.1 myname.dev.local
Happy
Now Chrome and IE should treat the certificate as trustworthy and load your website when you open up https://myname.dev.local
.
Firefox maintains its own certificate store. To add your cert here, you must open your website in FF and add it to the exceptions when FF warns you about the certificate.
For Edge browser there may be more action needed (see further down).
To test your certs, Firefox is your best choice. (Believe me, I'm a Chrome fan-boy myself, but FF is better in this case.)
Here are the reasons:
The certificate is not trusted because it is self-signed.
This warning is correct! As noted above, Firefox does not use the Windows certificate store and will only trust this certificate, if you add an exception for it. The button to do this is right below the warnings.
The certificate is not valid for the name ...
This warning shows, that you did something wrong. The (wildcard) domain of your certificate does not match the domain of your website. The problem must be solved by either changing your website's (sub-)domain or by issuing a new certificate that matches. In fact you could add an exception in FF even if the cert does not match, but you would never get a green padlock symbol in Chrome with such a combination.
Firefox can display many other nice and understandable cert warnings at this place, like expired certs, certs with outdated signing algorithms, etc. I found no other browser that gave me that level of feedback to nail down any problems.
In the above New-SelfSignedCertificate command we used the wildcard domain *.dev.local
.
You may think: Why not use *.local
?
Simple reason: It is illegal as a wildcard domain.
Wildcard certificates must contain at least a second level domain name.
So, domains of the form *.local
are nice to develop HTTP websites. But not so much for HTTPS, because you would be forced to issue a new matching certificate for each new project that you start.
Important side notes:
motör_head.dev.local
to your wildcard pattern *.dev.local
. They will comply when you switch to motoer-head.dev.local
.*.dev.local
matches myname.dev.local
but NOT other.myname.dev.local
! *.*.dev.local
) are NOT possible in certificates.
So other.myname.dev.local
can only be covered by a wildcard of the form *.myname.dev.local
. As a result, it is best not to use a forth level domain part. Put all your variations into the third level part. This way you will get along with a single certificate for all your dev sites.This is not really about self-signed certificates, but still related to the whole process:
After following the above steps, Edge may not show any content when you open up myname.dev.local
.
The reason is a characteristic feature of the network management of Windows 10 for Modern Apps, called "Network Isolation".
To solve that problem, open a command prompt with Administrator privileges and enter the following command once:
CheckNetIsolation LoopbackExempt -a -n=Microsoft.MicrosoftEdge_8wekyb3d8bbwe
More infos about Edge and Network Isolation can be found here: https://blogs.msdn.microsoft.com/msgulfcommunity/2015/07/01/how-to-debug-localhost-on-microsoft-edge/
(Three years late...) but I believe the answer to your second question is that SSRS essentially treats data from your datasets as unsorted; I'm not sure if it ignores any ORDER BY in the sql, or if it just assumes the data is unsorted.
To sort your groups in a particular order, you need to specify it in the report:
For the report I just created, the default sort order on the category was alphabetic on the category group which was basically a string code. But sometimes it can be useful to sort by some other characteristic of the data; for example, my report is of Average and Maximum processing times for messages identified by some code (the category). By setting the sort order of the group to be on [MaxElapsedMs], Z->A it draws my attention to the worst-performing message-types.
This sort of presentation won't be useful for every report but it can be an excellent tool to guide readers to have a better understanding of the data; though on other occasions you might prefer a report to have the same ordering every time it runs, in which case sorting on the category label itself may be best... and I guess there are circumstances where changing the sort order could harm understanding, such as if the categories implied some sort of ordering (such as date values?)
if you want to add the data in the increment order inside your associative array you can do this:
$newdata = array (

'wpseo_desc' => 'test',
'wpseo_metakey' => 'test'
);
// for recipe
$md_array["recipe_type"][] = $newdata;
//for cuisine
$md_array["cuisine"][] = $newdata;
this will get added to the recipe or cuisine depending on what was the last index.
Array push is usually used in the array when you have sequential index: $arr[0] , $ar[1].. you cannot use it in associative array directly. But since your sub array is had this kind of index you can still use it like this
array_push($md_array["cuisine"],$newdata);
here is a simple function to seperate multiple words and numbers from a string of any length, the re method only seperates first two words and numbers. I think this will help everyone else in the future,
def seperate_string_number(string):
previous_character = string[0]
groups = []
newword = string[0]
for x, i in enumerate(string[1:]):
if i.isalpha() and previous_character.isalpha():
newword += i
elif i.isnumeric() and previous_character.isnumeric():
newword += i
else:
groups.append(newword)
newword = i
previous_character = i
if x == len(string) - 2:
groups.append(newword)
newword = ''
return groups
print(seperate_string_number('10in20ft10400bg'))
# outputs : ['10', 'in', '20', 'ft', '10400', 'bg']
To avoid exceptions killing your app you should catch those exceptions and treat them the way you wish, defining the behavior for you app on those situations where the id is not found.
begin
current_user.comments.find(ids)
rescue
#do something in case of exception found
end
Here's more info on exceptions in ruby.
Thanks a lot to Chris.

I know this has been answered, but in VB.net above 2013 (the lowest I've personally used) you can just compare strings with an =
operator. This is the easiest way.
So basically:
If string1 = string2 Then
'do a thing
End If
As far as I can tell, it no longer is possible in Chrome or FireFox. It may still be possible in IE (at least pre-Edge).

You can do this using Input.setSelectionRange
, part of the Range API for interacting with text selections and the text cursor:
var searchInput = $('#Search');
// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;
searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);

Some languages have combining diacritics as language letters and accent diacritics to specify accent.
I think it is more safe to specify explicitly what diactrics you want to strip:
def strip_accents(string, accents=('COMBINING ACUTE ACCENT', 'COMBINING GRAVE ACCENT', 'COMBINING TILDE')):
accents = set(map(unicodedata.lookup, accents))
chars = [c for c in unicodedata.normalize('NFD', string) if c not in accents]
return unicodedata.normalize('NFC', ''.join(chars))
As long as you don't COMMIT or ROLLBACK a transaction, it's still "running" and potentially holding locks.
If your client (application or user) closes the connection to the database before committing, any still running transactions will be rolled back and terminated.
let my_u8: u8 = "42".parse::<u8>().unwrap();
let my_u32: u32 = "42".parse::<u32>().unwrap();
// or, to be safe, match the `Err`
match "foobar".parse::<i32>() {
Ok(n) => do_something_with(n),
Err(e) => weep_and_moan(),
}
str::parse::<u32>
returns a Result<u32, core::num::ParseIntError>
and Result::unwrap
"Unwraps a result, yielding the content of an Ok
[or] panics if the value is an Err
, with a panic message provided by the Err
's value."
str::parse
is a generic function, hence the type in angle brackets.
If it is possible pass the params through regular GET/POST with a different name and let your server side code handles it.
I had a similar issue with my own proxy to bypass CORS and I got the same error of POST->OPTION in Chrome. It was the Authorization
header in my case ("x-li-format"
and "X-UserName"
here in your case.) I ended up passing it in a dummy format (e.g. AuthorizatinJack
in GET) and I changed the code for my proxy to turn that into a header when making the call to the destination. Here it is in PHP:
if (isset($_GET['AuthorizationJack'])) {
$request_headers[] = "Authorization: Basic ".$_GET['AuthorizationJack'];
}
I had a similar but it was dealing with dates. Query to show all items for the last month, works great without conditions until Jan. In order for it work correctly, needed to add a year and month variable
declare @yr int
declare @mth int
set @yr=(select case when month(getdate())=1 then YEAR(getdate())-1 else YEAR(getdate())end)
set @mth=(select case when month(getdate())=1 then month(getdate())+11 else month(getdate())end)
Now I just add the variable into condition: ...
(year(CreationTime)=@yr and MONTH(creationtime)=@mth)
Be careful, the solution proposed with $a = array_combine($a, $a);
will not work for numeric values.
I for example wanted to have a memory array(128,256,512,1024,2048,4096,8192,16384)
to be the keys as well as the values however PHP manual states:
If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.
So I solved it like this:
foreach($array as $key => $val) {
$new_array[$val]=$val;
}
You are getting AttributeError
because you're calling groups
on None
, which hasn't any methods.
regex.search
returning None
means the regex couldn't find anything matching the pattern from supplied string.
when using regex, it is nice to check whether a match has been made:
Result = re.search(SearchStr, htmlString)
if Result:
print Result.groups()
sys.argv
represents the command line options you execute a script with.
sys.argv[0]
is the name of the script you are running. All additional options are contained in sys.argv[1:]
.
You are attempting to open a file that uses sys.argv[1]
(the first argument) as what looks to be the directory.
Try running something like this:

Try Winhttrack
...offline browser utility.
It allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site's relative link-structure. Simply open a page of the "mirrored" website in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads. HTTrack is fully configurable, and has an integrated help system.
WinHTTrack is the Windows 2000/XP/Vista/Seven release of HTTrack, and WebHTTrack the Linux/Unix/BSD release...

Ok, I'll take a stab at this. If you want to work with PHP, you will need to install and configure both PHP and a webserver on your machine. This article might get you started: PHP Manual: Installation on Windows systems
Once you have your environment setup, you can start working with webforms. Directly From the article: Processing form data with PHP:
For this example you will need to create two pages. On the first page we will create a simple HTML form to collect some data. Here is an example:
<html> <head> <title>Test Page</title> </head> <body> <h2>Data Collection</h2><p> <form action="process.php" method="post"> <table> <tr> <td>Name:</td> <td><input type="text" name="Name"/></td> </tr> <tr> <td>Age:</td> <td><input type="text" name="Age"/></td> </tr> <tr> <td colspan="2" align="center"> <input type="submit"/> </td> </tr> </table> </form> </body> </html>
This page will send the Name and Age data to the page process.php. Now lets create process.php to use the data from the HTML form we made:
<?php
print "Your name is ". $Name;
print "<br />";
print "You are ". $Age . " years old";
print "<br />"; $old = 25 + $Age;
print "In 25 years you will be " . $old . " years old";
?>
As you may be aware, if you leave out the method="post" part of the form, the URL with show the data. For example if your name is Bill Jones and you are 35 years old, our process.php page will display as http://yoursite.com/process.php?Name=Bill+Jones&Age=35 If you want, you can manually change the URL in this way and the output will change accordingly.
Additional JavaScript Example
This single file example takes the html from your question and ties the onSubmit event of the form to a JavaScript function that pulls the values of the 2 textboxes and displays them in an alert box.
Note: document.getElementById("fname").value
gets the object with the ID
tag that equals fname
and then pulls it's value
- which in this case is the text in the First Name textbox.
<html>
<head>
<script type="text/javascript">
function ExampleJS(){
var jFirst = document.getElementById("fname").value;
var jLast = document.getElementById("lname").value;
alert("Your name is: " + jFirst + " " + jLast);
}
</script>
</head>
<body>
<FORM NAME="myform" onSubmit="JavaScript:ExampleJS()">
First name: <input type="text" id="fname" name="firstname" /><br />
Last name: <input type="text" id="lname" name="lastname" /><br />
<input name="Submit" type="submit" value="Update" />
</FORM>
</body>
</html>
Generally, the system should be handling view controller instantiation with a storyboard. What you want is to traverse the viewController hierarchy by grabbing a reference to the self.window.rootViewController
as opposed to initializing view controllers, which should already be initialized correctly if you've setup your storyboard properly.
So, let's say your rootViewController
is a UINavigationController and then you want to send something to its top view controller, you would do it like this in your AppDelegate's didFinishLaunchingWithOptions
:
UINavigationController *nav = (UINavigationController *) self.window.rootViewController;
MyViewController *myVC = (MyViewController *)nav.topViewController;
myVC.data = self.data;
In Swift if would be very similar:
let nav = self.window.rootViewController as! UINavigationController;
let myVC = nav.topViewController as! MyViewController
myVc.data = self.data
You really shouldn't be initializing view controllers using storyboard id's from the app delegate unless you want to bypass the normal way storyboard is loaded and load the whole storyboard yourself. If you're having to initialize scenes from the AppDelegate you're most likely doing something wrong. I mean imagine you, for some reason, want to send data to a view controller way down the stack, the AppDelegate shouldn't be reaching way into the view controller stack to set data. That's not its business. It's business is the rootViewController. Let the rootViewController handle its own children! So, if I were bypassing the normal storyboard loading process by the system by removing references to it in the info.plist file, I would at most instantiate the rootViewController using instantiateViewControllerWithIdentifier:
, and possibly its root if it is a container, like a UINavigationController. What you want to avoid is instantiating view controllers that have already been instantiated by the storyboard. This is a problem I see a lot. In short, I disagree with the accepted answer. It is incorrect unless the posters means to remove loading of the storyboard from the info.plist since you will have loaded 2 storyboards otherwise, which makes no sense. It's probably not a memory leak because the system initialized the root scene and assigned it to the window, but then you came along and instantiated it again and assigned it again. Your app is off to a pretty bad start!
A combination of basename and cut works fine, even in case of double ending like .tar.gz
:
fbname=$(basename "$fullfile" | cut -d. -f1)
Would be interesting if this solution needs less arithmetic power than Bash Parameter Expansion.
Just my 2 cents. The below command should do the trick, as answered earlier
curl -vs google.com 2>&1
However if need to get the output to a file,
curl -vs google.com > out.txt 2>&1
should work.
In order to get the refresh_token
you need to include access_type=offline
in the OAuth request URL. When a user authenticates for the first time you will get back a non-nil refresh_token
as well as an access_token
that expires.
If you have a situation where a user might re-authenticate an account you already have an authentication token for (like @SsjCosty mentions above), you need to get back information from Google on which account the token is for. To do that, add profile
to your scopes. Using the OAuth2 Ruby gem, your final request might look something like this:
client = OAuth2::Client.new(
ENV["GOOGLE_CLIENT_ID"],
ENV["GOOGLE_CLIENT_SECRET"],
authorize_url: "https://accounts.google.com/o/oauth2/auth",
token_url: "https://accounts.google.com/o/oauth2/token"
)
# Configure authorization url
client.authorize_url(
scope: "https://www.googleapis.com/auth/analytics.readonly profile",
redirect_uri: callback_url,
access_type: "offline",
prompt: "select_account"
)
Note the scope has two space-delimited entries, one for read-only access to Google Analytics, and the other is just profile
, which is an OpenID Connect standard.
This will result in Google providing an additional attribute called id_token
in the get_token
response. To get information out of the id_token, check out this page in the Google docs. There are a handful of Google-provided libraries that will validate and “decode” this for you (I used the Ruby google-id-token gem). Once you get it parsed, the sub
parameter is effectively the unique Google account ID.
Worth noting, if you change the scope, you'll get back a refresh token again for users that have already authenticated with the original scope. This is useful if, say, you have a bunch of users already and don't want to make them all un-auth the app in Google.
Oh, and one final note: you don't need prompt=select_account
, but it's useful if you have a situation where your users might want to authenticate with more than one Google account (i.e., you're not using this for sign-in / authentication).

If you really want to set the label width independent of the content, I find that the easiest way is this:
Now the label is of constant width, but it adapts its height automatically.
Then for dynamic text, decrease the font size. If necessary, use this snippet in the sub where the label text is set:
If Me.Size.Height - (Label12.Location.Y + Label12.Height) < 20 Then
Dim naam As String = Label12.Font.Name
Dim size As Single = Label12.Font.SizeInPoints - 1
Label12.Font = New Font(naam, size)
End If
I recently discovered a project called OniVim, which is an electron-based front-end for NeoVim that comes with very nice autocomplete for several languages out of the box, and since it's basically just a wrapper around NeoVim, you have the full power of vim at your disposal if the GUI doesn't meet your needs. It's still in early development, but it is rapidly improving and there is a really active community around it. I have been using vim for over 10 years and started giving Oni a test drive a few weeks ago, and while it does have some bugs here and there it hasn't gotten in my way. I would strongly recommend it to new vim users who are still getting their vim-fingers!

From the horse's mouth: Explicit line joining
Two or more physical lines may be joined into logical lines using backslash characters (
\
), as follows: when a physical line ends in a backslash that is not part of a string literal or comment, it is joined with the following forming a single logical line, deleting the backslash and the following end-of-line character. For example:if 1900 < year < 2100 and 1 <= month <= 12 \ and 1 <= day <= 31 and 0 <= hour < 24 \ and 0 <= minute < 60 and 0 <= second < 60: # Looks like a valid date return 1
A line ending in a backslash cannot carry a comment. A backslash does not continue a comment. A backslash does not continue a token except for string literals (i.e., tokens other than string literals cannot be split across physical lines using a backslash). A backslash is illegal elsewhere on a line outside a string literal.

Had similar problems recently. Would suggest you carefully check if the user you're connecting with has proper authorizations on the remote machine.
You can review permissions using the following command.

It fixed it for me.
Beside accepted answer, you need to hold a reference of listener and remove when you don't need it. Otherwise you will get a null pointer exception for your ScrollView and memory leak (mentioned in comments of accepted answer).
You can implement OnScrollChangedListener in your activity/fragment.
MyFragment : ViewTreeObserver.OnScrollChangedListener
Add it to scrollView when your view is ready.
scrollView.viewTreeObserver.addOnScrollChangedListener(this)
Remove listener when no longer need (ie. onPause())
scrollView.viewTreeObserver.removeOnScrollChangedListener(this)
enter the values as 0:mm:ss
and format as [m]:ss
as this is now in the mins & seconds, simple arithmetic will allow you to calculate your statistics
This is an example of a good one and also an example of why you would never want to write one. It is a Fowler / Noll / Vo (FNV) Hash which is equal parts computer science genius and pure voodoo:
unsigned fnv_hash_1a_32 ( void *key, int len ) {
unsigned char *p = key;
unsigned h = 0x811c9dc5;
int i;
for ( i = 0; i < len; i++ )
h = ( h ^ p[i] ) * 0x01000193;
return h;
}
unsigned long long fnv_hash_1a_64 ( void *key, int len ) {
unsigned char *p = key;
unsigned long long h = 0xcbf29ce484222325ULL;
int i;
for ( i = 0; i < len; i++ )
h = ( h ^ p[i] ) * 0x100000001b3ULL;
return h;
}
Edit:
In addition to all the answers provided so far, another reason for causing this exception can happen when you are saving data from list to database using ADO.Net.
Many developers will mistakenly use for
loop or foreach
and leave the SqlCommand
to execute outside the loop, to avoid that make sure that you have like this code sample for example:
public static void Save(List<myClass> listMyClass)
{
using (var Scope = new System.Transactions.TransactionScope())
{
if (listMyClass.Count > 0)
{
for (int i = 0; i < listMyClass.Count; i++)
{
SqlCommand cmd = new SqlCommand("dbo.SP_SaveChanges", myConnection);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Clear();
cmd.Parameters.AddWithValue("@ID", listMyClass[i].ID);
cmd.Parameters.AddWithValue("@FirstName", listMyClass[i].FirstName);
cmd.Parameters.AddWithValue("@LastName", listMyClass[i].LastName);
try
{
myConnection.Open();
cmd.ExecuteNonQuery();
}
catch (SqlException sqe)
{
throw new Exception(sqe.Message);
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
finally
{
myConnection.Close();
}
}
}
else
{
throw new Exception("List is empty");
}
Scope.Complete();
}

Rejecting the WiFi networks idea!
Sorry folks... I don't see it. Using WiFi networks around you seems to be a highly inaccurate and ineffective method of collecting data. WiFi networks these days simply don't stay long in one place.
Think about it, the WiFi networks change every day. Not to mention MiFi and Adhoc networks which are "designed" to be mobile and travel with the users. Equipment breaks, network settings change, people move... Relying on "WiFi Networks" in your area seems highly inaccurate and in the end may not even offer a significant improvement in granularity over IP lookup.
I think the idea that iPhone users are "scanning and sending" the WiFi survey data back to google, and the wardriving, perhaps in conjunction with the Google Maps "Street View" mapping might seem like a very possible method of collecting this data however, in practicality, it does not work as a business model.
Oh and btw, I forgot to mention in my prior post... when I originally pulled my location the time I was pinpointed "precisely" on the map I was connecting to a router from my desktop over an ethernet connection. I don't have a WiFi card on my desktop.
So if that "nearby WiFi networks" theory was true... then I shouldn't have been able to pinpoint my location with such precision.
I'll call my ISP, SKyrim, and ask them as to whether they share their network topology to enable geolocation on their networks.
Even both eacceleator and xcache perform quite well during moderate loads, APC maintains its stability under serious request intensity. If we're talking about a few hundred requests/sec here, you'll not feel the difference. But if you're trying to respond more, definetely stick with APC. Especially if your application has overly dynamic characteristics which will likely cause locking issues under such loads. http://www.ipsure.com/blog/2011/eaccelerator-as-zend-extension-high-load-averages-issue/ may help.
You can use the simple mailto

<a href="mailto:[email protected]">Click here to mail</a>
Once clicked, it will open your Outlook or whatever email client you have set.
Try this:
Create A Macro with the following thing inside:
Selection.Copy
ActiveCell.Offset(1, 0).Select
ActiveSheet.Paste
ActiveCell.Offset(-1, 1).Select
Selection.Copy
ActiveCell.Offset(1, 0).Select
ActiveSheet.Paste
ActiveCell.Offset(0, -1).Select
That particular macro will copy the current cell (place your cursor in the VOL cell you wish to copy) down one row and then copy the CAP cell also.
This is only a single loop so you can automate copying VOL and CAP of where your current active cell (where your cursor is) to down 1 row.
Just put it inside a For loop statement to do it x number of times. like:
For i = 1 to 100 'Do this 100 times
Selection.Copy
ActiveCell.Offset(1, 0).Select
ActiveSheet.Paste
ActiveCell.Offset(-1, 1).Select
Selection.Copy
ActiveCell.Offset(1, 0).Select
ActiveSheet.Paste
ActiveCell.Offset(0, -1).Select
Next i

We are using the cordova-custom-config
plugin to manage our Android configuration. In this case the solution was to add a new custom-preference
to our config.xml
:
<platform name="android">
<preference name="orientation" value="portrait" />
<!-- ... other settings ... -->
<!-- Allow http connections (by default Android only allows https) -->
<!-- See: https://stackoverflow.com/questions/54752716/ -->
<custom-preference
name="android-manifest/application/@android:usesCleartextTraffic"
value="true" />
</platform>
Does anybody know how to do this only for development builds? I would be happy for release builds to leave this setting false
.
(I see the iOS configuration offers buildType="debug"
for that, but I'm not sure if this applies to Android configuration.)
To add onto bobince's answer... If whatever tool/library you using uses Xpath 2.0, you can also do this:
//*[count(index-of(tokenize(@class, '\s+' ), $classname)) = 1]
count() is apparently needed because index-of() returns a sequence of each index it has a match at in the string.
If you use %pylab inline
you can (on a new line) insert the following command:
%pylab inline
pylab.rcParams['figure.figsize'] = (10, 6)
This will set all figures in your document (unless otherwise specified) to be of the size (10, 6)
, where the first entry is the width and the second is the height.

As Brad Wilson states in his answer here:
ModelState.IsValid tells you if any model errors have been added to ModelState.
The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.
Try using :-
if (!ModelState.IsValid)
{
var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));
// Breakpoint, Log or examine the list with Exceptions.
}
If it helps catching you the error. Courtesy this and this
I came by the same error on an old 2010 Exchange Server. A service(Exchange mailbox replication service) was giving out the above error and the migration process could not be continued. Searching through the internet, i came by this link which stated the below:
The Exchange GRE fails to open when installed for the first time or if any changes are made to the IIS server. It fails with snap-in error and when you try to open the snap-in page, the following content is displayed:
This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. If your service is being hosted in IIS you can fix the problem by setting 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' to true or specifying 'system.serviceModel/serviceHostingEnvironment/baseAddressPrefixFilters'."
Cause: This error occurs because http port number 443 is already in use by another application and the IIS server is not configured to handle multiple binding to the same port.
Solution: Configure IIS server to handle multiple port bindings. Contact the vendor (Microsoft) to configure it.
Since these services were offered from an IIS Web Server, checking the Bindings on the Root Site fixed the problem. Someone had messed up the Site Bindings, defining rules that were overlapping themselves and messed up the services.
Fixing the correct Bindings resolved the problem, in my case, and i did not have to configure the Web.Config.
Although a bit late, I've come across this question while searching the solution for the same problem, so I hope it can be of any help...
Found myself in the same darkness than you. Just found this article, which explains some new hints introduced in NetBeans 7.4, including this one:
https://blogs.oracle.com/netbeansphp/entry/improve_your_code_with_new
The reason why it has been added is because superglobals usually are filled with user input, which shouldn't ever be blindly trusted. Instead, some kind of filtering should be done, and that's what the hint suggests. Filter the superglobal value in case it has some poisoned content.
For instance, where I had:
$_SERVER['SERVER_NAME']
I've put instead:
filter_input(INPUT_SERVER, 'SERVER_NAME', FILTER_SANITIZE_STRING)
You have the filter_input and filters doc here:
Golang does not support implicit unpacking of an slice (unlike python) and that is the reason this would not work. Like the examples given above, we would need to workaround it.
One side note:
The implicit unpacking happens for variadic functions in go:
func varParamFunc(params ...int) {
}
varParamFunc(slice1...)
Kevin Sliech provided a great solution.
I now use the below code in my main UIViewController subclass.
One small alteration i made was to check to see if the best presentation controller is not a plain UIViewController. If not, it's got to be some VC that presents a plain VC. Thus we return the VC that's being presented instead.
- (UIViewController *)bestPresentationController
{
UIViewController *bestPresentationController = [UIApplication sharedApplication].keyWindow.rootViewController;
if (![bestPresentationController isMemberOfClass:[UIViewController class]])
{
bestPresentationController = bestPresentationController.presentedViewController;
}
return bestPresentationController;
}
Seems to all work out so far in my testing.
Thank you Kevin!

This may also add to understanding of the difference between those two operators:
df <- data.frame(
a = rnorm(10),
b <- rnorm(10)
)
For the first element R has assigned values and proper name, while the name of the second element looks a bit strange.
str(df)
# 'data.frame': 10 obs. of 2 variables:
# $ a : num 0.6393 1.125 -1.2514 0.0729 -1.3292 ...

You can use the logical 'OR' operator in place of the Elvis operator:
For example displayname = user.name || "Anonymous"
.
But Javascript currently doesn't have the other functionality. I'd recommend looking at CoffeeScript if you want an alternative syntax. It has some shorthand that is similar to what you are looking for.
For example The Existential Operator
zip = lottery.drawWinner?().address?.zipcode
Function shortcuts
()-> // equivalent to function(){}
Sexy function calling
func 'arg1','arg2' // equivalent to func('arg1','arg2')
There is also multiline comments and classes. Obviously you have to compile this to javascript or insert into the page as <script type='text/coffeescript>'
but it adds a lot of functionality :) . Using <script type='text/coffeescript'>
is really only intended for development and not production.
Here is the one liner i use, from terminal, to test the content of yml file(s):

"file"=>"TacoCloud.log",
"level"=>

You need to distinguish between a language and an implementation. Python is a language,
According to Wikipedia, "A programming language is a notation for writing programs, which are specifications of a computation or algorithm". This means that it's simply the rules and syntax for writing code. Separately we have a programming language implementation which in most cases, is the actual interpreter or compiler.
Python is a language. CPython is the implementation of Python in C. Jython is the implementation in Java, and so on.
To sum up: You are already using CPython (if you downloaded from here).
The JavaScript module pattern uses closures. Its nice pattern allows you to have something alike "public" and "private" variables.
var myNamespace = (function () {
var myPrivateVar, myPrivateMethod;
// A private counter variable
myPrivateVar = 0;
// A private function which logs any arguments
myPrivateMethod = function(foo) {
console.log(foo);
};
return {
// A public variable
myPublicVar: "foo",
// A public function utilizing privates
myPublicFunction: function(bar) {
// Increment our private counter
myPrivateVar++;
// Call our private method using bar
myPrivateMethod(bar);
}
};
})();
This works fine ....
int a = nextInt();
int b = nextInt();
int c = nextInt();
Or you can read them in a loop
I don't think there is a function that does all that in a single call. However you can find the Gaussian probability density function in scipy.stats
.
So the simplest way I could come up with is:
import numpy as np
import matplotlib.pyplot as plt
from scipy.stats import norm
# Plot between -10 and 10 with .001 steps.
x_axis = np.arange(-10, 10, 0.001)
# Mean = 0, SD = 2.
plt.plot(x_axis, norm.pdf(x_axis,0,2))
plt.show()

The Balusc gives a very useful overview answer on this subject. But there is one alternative he does not present: The Roll-your-own generic converter that handles complex objects as the selected item. This is very complex to do if you want to handle all cases, but pretty simple for simple cases.
The code below contains an example of such a converter. It works in the same spirit as the OmniFaces SelectItemsConverter as it looks through the children of a component for UISelectItem(s)
containing objects. The difference is that it only handles bindings to either simple collections of entity objects, or to strings. It does not handle item groups, collections of SelectItem
s, arrays and probably a lot of other things.
The entities that the component binds to must implement the IdObject
interface. (This could be solved in other way, such as using toString
.)
Note that the entities must implement equals
in such a way that two entities with the same ID compares equal.
The only thing that you need to do to use it is to specify it as converter on the select component, bind to an entity property and a list of possible entities:
<h:selectOneMenu value="#{bean.user}" converter="selectListConverter">
<f:selectItem itemValue="unselected" itemLabel="Select user..."/>
<f:selectItem itemValue="empty" itemLabel="No user"/>
<f:selectItems value="#{bean.users}" var="user" itemValue="#{user}" itemLabel="#{user.name}" />
</h:selectOneMenu>
Converter:
/**
* A converter for select components (those that have select items as children).
*
* It convertes the selected value string into one of its element entities, thus allowing
* binding to complex objects.
*
* It only handles simple uses of select components, in which the value is a simple list of
* entities. No ItemGroups, arrays or other kinds of values.
*
* Items it binds to can be strings or implementations of the {@link IdObject} interface.
*/
@FacesConverter("selectListConverter")
public class SelectListConverter implements Converter {
public static interface IdObject {
public String getDisplayId();
}
@Override
public Object getAsObject(FacesContext context, UIComponent component, String value) {
if (value == null || value.isEmpty()) {
return null;
}

import java.util.Base64;
.... Just making it clear that this answer uses the java.util.Base64 package, without using any third-party libraries.
String crntImage=<a valid base 64 string>
byte[] data = Base64.getDecoder().decode(crntImage);

Here is another approach that allows you to use //
to include comments:
return (
<div>
<div>
{
// Your comment goes in here.
}
</div>
{
// Note that comments using this style must be wrapped in curly braces!
}
</div>
);
The catch here is you cannot include a one-line comment using this approach. For example, this does not work:
{// your comment cannot be like this}
because the closing bracket }
is considered to be part of the comment and is thus ignored, which throws an error.
You have to set to element_blank()
in theme()
elements you need to remove
ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut))+
theme(axis.title.x=element_blank(),
axis.text.x=element_blank(),
axis.ticks.x=element_blank())
This example from Java Doc helped me understand the concepts clearly:
class Driver { // ...
void main() throws InterruptedException {
CountDownLatch startSignal = new CountDownLatch(1);
CountDownLatch doneSignal = new CountDownLatch(N);
for (int i = 0; i < N; ++i) // create and start threads
new Thread(new Worker(startSignal, doneSignal)).start();
doSomethingElse(); // don't let run yet
startSignal.countDown(); // let all threads proceed
doSomethingElse();
doneSignal.await(); // wait for all to finish
}
}
class Worker implements Runnable {
private final CountDownLatch startSignal;
private final CountDownLatch doneSignal;
Worker(CountDownLatch startSignal, CountDownLatch doneSignal) {
this.startSignal = startSignal;
this.doneSignal = doneSignal;
}
public void run() {
try {
startSignal.await();
doWork();
doneSignal.countDown();
} catch (InterruptedException ex) {} // return;
}
void doWork() { ... }
}
Visual interpretation:
Evidently, CountDownLatch
allows one thread (here Driver
) to wait until a bunch of running threads (here Worker
) are done with their execution.
Something like this perhaps?
x<-rnorm(100000,mean=10, sd=2)
hist(x,breaks=150,xlim=c(0,20),freq=FALSE)

minimumFontSize
is deprecated in iOS 6.
So use minimumScaleFactor

lbl.minimumScaleFactor = 0.5

lbl.adjustsFontSizeToFitWidth = true
lbl.minimumScaleFactor = 0.5

if ($elem.parents('.left').length != 0) {
//someone has this class
}
I found the following command to run from command line:
vlc.exe --extraintf=http:logger --verbose=2 --file-logging --logfile=vlc-log.txt
Converting your set into an array may also help you for iterating over the elements:
Object[] array = set.toArray();
for(int i=0; i<array.length; i++)
Object o = array[i];
Numbering an items in the java array should start from zero. This was i think we can have access to Integer.MAX_VALUE+1 an items.
If you mean you want to sort by date first then by names
SELECT id, name, form_id, DATE(updated_at) as date
FROM wp_frm_items
WHERE user_id = 11 && form_id=9
ORDER BY updated_at DESC,name ASC
This will sort the records by date first, then by names

Here's how you can debug CORS requests using curl.
Sending a regular CORS request using cUrl:
curl -H "Origin: http://example.com" --verbose \
https://www.googleapis.com/discovery/v1/apis?fields=
The -H "Origin: http://example.com"
flag is the third party domain making the request. Substitute in whatever your domain is.
The --verbose
flag prints out the entire response so you can see the request and response headers.
The url I'm using above is a sample request to a Google API that supports CORS, but you can substitute in whatever url you are testing.
The response should include the Access-Control-Allow-Origin
header.
Sending a preflight request using cUrl:
curl -H "Origin: http://example.com" \
-H "Access-Control-Request-Method: POST" \
-H "Access-Control-Request-Headers: X-Requested-With" \
-X OPTIONS --verbose \
https://www.googleapis.com/discovery/v1/apis?fields=
This looks similar to the regular CORS request with a few additions:
The -H
flags send additional preflight request headers to the server
The -X OPTIONS
flag indicates that this is an HTTP OPTIONS request.
If the preflight request is successful, the response should include the Access-Control-Allow-Origin
, Access-Control-Allow-Methods
, and Access-Control-Allow-Headers
response headers. If the preflight request was not successful, these headers shouldn't appear, or the HTTP response won't be 200.
You can also specify additional headers, such as User-Agent
, by using the -H
flag.

This is pure JavaScript, based on the answer by @Fontas but with safety code to return an empty string (and avoid a TypeError
) if there isn't a selected radio button:
var genderSRadio = document.querySelector("input[name=genderS]:checked");
var genderSValue = genderSRadio ? genderSRadio.value : "";
The code breaks down like this:
<input>
type, (b) has a name
attribute of genderS
, and (c) is checked.genderSRadio
variable is truthy if Line 1 finds the control and null/falsey if it doesn't.For JQuery, use @jbabey's answer, and note that if there isn't a selected radio button it will return undefined
.
I think there is a much simpler solution to this.
name = input('What is your name? ')
print('Hello %s' % (name) )
Then run your program in the command line
python greeter.py | clip
This will pipe the output of your file to the clipboard
You can join to the same table on the fields that would be duplicated and then anti-join on the id field. Select the id field from the first table alias (tn1) and then use the array_agg function on the id field of the second table alias. Finally, for the array_agg function to work properly, you will group the results by the tn1.id field. This will produce a result set that contains the the id of a record and an array of all the id's that fit the join conditions.
select tn1.id,
array_agg(tn2.id) as duplicate_entries,
from table_name tn1 join table_name tn2 on
tn1.year = tn2.year
and tn1.sid = tn2.sid
and tn1.user_id = tn2.user_id
and tn1.cid = tn2.cid
and tn1.id <> tn2.id
group by tn1.id;
Obviously, id's that will be in the duplicate_entries array for one id, will also have their own entries in the result set. You will have to use this result set to decide which id you want to become the source of 'truth.' The one record that shouldn't get deleted. Maybe you could do something like this:
with dupe_set as (
select tn1.id,
array_agg(tn2.id) as duplicate_entries,
from table_name tn1 join table_name tn2 on
tn1.year = tn2.year
and tn1.sid = tn2.sid
and tn1.user_id = tn2.user_id
and tn1.cid = tn2.cid
and tn1.id <> tn2.id
group by tn1.id
order by tn1.id asc)
select ds.id from dupe_set ds where not exists
(select de from unnest(ds.duplicate_entries) as de where de < ds.id)
Selects the lowest number ID's that have duplicates (assuming the ID is increasing int PK). These would be the ID's that you would keep around.
I think the most elegant solution is to pass a lambda function to "type", as mentioned by Chepner. In addition to this, if you do not know beforehand what the delimiter of your list will be, you can also pass multiple delimiters to re.split:
# python3 test.py -l "abc xyz, 123"
import re
import argparse
parser = argparse.ArgumentParser(description='Process a list.')
parser.add_argument('-l', '--list',
type=lambda s: re.split(' |, ', s),
required=True,
help='comma or space delimited list of characters')
args = parser.parse_args()
print(args.list)
# Output: ['abc', 'xyz', '123']

I found the working dll files for PHP 5.4.4
I don't knowhow stable they are but they work for sure. Credits goes to this link.

It is the 2.2.5.0 version, I noticed after compiling it (for PHP 5.4.4).
Please note that it is not 2.2.6 but works. I also mirrored them in my own FTP. Mirror links:

In SQL Server 2008 and newer you can cast the DateTime
to a Date
, which removes the time element.
WHERE Orders.OrderStatus = 'Shipped'
AND Orders.ShipDate >= (cast(GETDATE()-6 as date))
In SQL Server 2005 and below you can use:
WHERE Orders.OrderStatus = 'Shipped'
AND Orders.ShipDate >= DateAdd(Day, Datediff(Day,0, GetDate() -6), 0)
This is hacky, but:
resetPar <- function() {
dev.new()
op <- par(no.readonly = TRUE)
dev.off()
op
}
works after a fashion, but it does flash a new device on screen temporarily...
E.g.:
> par(mfrow = c(2,2)) ## some random par change
> par("mfrow")
[1] 2 2
> par(resetPar()) ## reset the pars to defaults
> par("mfrow") ## back to default
[1] 1 1
Some versions of Excel don't have date-time formats available in the standard pick lists, but you can just enter a custom format string such as yyyy-mm-dd hh:mm:ss by:
This works on my Excel 2010
Rather than trying to output to the console, Log
will output to LogCat which you can find in Eclipse by going to: Window->Show View->Other…->Android->LogCat
Have a look at the reference for Log
.
The benefits of using LogCat are that you can print different colours depending on your log type, e.g.: Log.d
prints blue, Log.e
prints orange. Also you can filter by log tag, log message, process id and/or by application name. This is really useful when you just want to see your app's logs and keep the other system stuff separate.
I played around with nico's answer a little and it felt jumpy. Did a bit of investigation and found window.requestAnimationFrame
which is a function that is called on each repaint cycle. This allows for a more clean-looking animation. Still trying to hone in on good default values for step size but for my example things look pretty good using this implementation.
var smoothScroll = function(elementId) {
var MIN_PIXELS_PER_STEP = 16;
var MAX_SCROLL_STEPS = 30;
var target = document.getElementById(elementId);
var scrollContainer = target;
do {
scrollContainer = scrollContainer.parentNode;
if (!scrollContainer) return;
scrollContainer.scrollTop += 1;
} while (scrollContainer.scrollTop == 0);
var targetY = 0;
do {
if (target == scrollContainer) break;
targetY += target.offsetTop;
} while (target = target.offsetParent);
var pixelsPerStep = Math.max(MIN_PIXELS_PER_STEP,
(targetY - scrollContainer.scrollTop) / MAX_SCROLL_STEPS);
var stepFunc = function() {
scrollContainer.scrollTop =
Math.min(targetY, pixelsPerStep + scrollContainer.scrollTop);
if (scrollContainer.scrollTop >= targetY) {
return;
}
window.requestAnimationFrame(stepFunc);
};
window.requestAnimationFrame(stepFunc);
}
Solved : Just put this method in doInBackround Class... and pass the message
public void setProgressText(final String progressText){
Handler handler = new Handler(Looper.getMainLooper()) {
@Override
public void handleMessage(Message msg) {
// Any UI task, example
progressDialog.setMessage(progressText);
}
};
handler.sendEmptyMessage(1);
}
var full_url = document.URL; // Get current url
var url_array = full_url.split('/') // Split the string into an array with / as separator
var last_segment = url_array[url_array.length-1]; // Get the last part of the array (-1)
alert( last_segment ); // Alert last segment
