Here's my regexp pure JavaScript solution:
function highlight(text) {
document.body.innerHTML = document.body.innerHTML.replace(
new RegExp(text + '(?!([^<]+)?<)', 'gi'),
'<b style="background-color:#ff0;font-size:100%">$&</b>'
);
}
As an alternative:
listView.setSelector(android.R.color.transparent);
or
listView.setSelector(new StateListDrawable());
I would recommend EditArea for live editing of a syntax hightlighted textarea.
The full modern solution to your problem is purely CSS-based, but note that older browsers won't support it, in which cases you'd need to fallback to solutions such as the others have provided.
So in pure CSS:
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;
However the mouse cursor will still change to a caret when over the element's text, so you add to that:
cursor: default;
Modern CSS is pretty elegant.
<html>
<body>
<input id="check1" type="checkbox" checked="" name="copyNewAddrToBilling">
</body>
<script language="javascript">
document.getElementById("check1").checked = true;
document.getElementById("check1").checked = false;
</script>
</html>
I have added the language attribute to the script element, but it is unnecessary because all browsers use this as a default, but it leaves no doubt what this example is showing.
If you want to use javascript to access elements, it has a very limited set of GetElement* functions. So you are going to need to get into the habit of giving every element a UNIQUE id attribute.
@Debasish Sahu, your answer is an answer to another question, namely: how to know which button (or any other control) was clicked when there is a common handler for a couple of controls? So I'm giving an answer to this question how I usually do it, almost the same as yours, but note that also works without type conversion when it handles the same type of Controls:
Private Sub btn_done_clicked(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim selectedBtn As Button = sender
MsgBox("you have clicked button " & selectedBtn.Name)
End Sub
I advice you to try 2Printer command line tool from: http://www.doc2prn.com/
Command line example to print all PDF files from folder "C:\Input" is below. You can simple call it from your C# code.
2Printer.exe -s "C:\Input*.PDF" -prn "Canon MP610 series Printer"
This question is an old one, but it shows up at the top of Google when searching for how to run a single test. I don't know if it's a recent addition, but to run a single test out of a spec you can do the following:
rspec path/to/spec:<line number>
where -line number- is a line number that contains part of your test. For example, if you had a spec like:
1:
2: it "should be awesome" do
3: foo = 3
4: foo.should eq(3)
5: end
6:
Let's say it's saved in spec/models/foo_spec.rb. Then you would run:
rspec spec/models/foo_spec.rb:2
and it would just run that one spec. In fact, that number could be anything from 2 to 5.
Hope this helps!
Let's revisit key phases of Mapreduce program.
The map phase is done by mappers. Mappers run on unsorted input key/values pairs. Each mapper emits zero, one, or multiple output key/value pairs for each input key/value pairs.
The combine phase is done by combiners. The combiner should combine key/value pairs with the same key. Each combiner may run zero, once, or multiple times.
The shuffle and sort phase is done by the framework. Data from all mappers are grouped by the key, split among reducers and sorted by the key. Each reducer obtains all values associated with the same key. The programmer may supply custom compare functions for sorting and a partitioner for data split.
The partitioner decides which reducer will get a particular key value pair.
The reducer obtains sorted key/[values list] pairs, sorted by the key. The value list contains all values with the same key produced by mappers. Each reducer emits zero, one or multiple output key/value pairs for each input key/value pair.
Have a look at this javacodegeeks article by Maria Jurcovicova and mssqltips article by Datta for a better understanding
Below is the image from safaribooksonline article
A relative URL without a scheme (http: or https:) is valid, per RFC 3986: "Uniform Resource Identifier (URI): Generic Syntax", Section 4.2. If a client chokes on it, then it's the client's fault because they're not complying with the URI syntax specified in the RFC.
Your example is valid and should work. I've used that relative URL method myself on heavily trafficked sites and have had zero complaints. Also, we test our sites in Firefox, Safari, IE6, IE7 and Opera. These browsers all understand that URL format.
When you use float without width, there remains some space in that row. To block this space you can use clear:both;
in next element.
A rather nice way to handle this for missing COM classes:
Dim o:Set o = Nothing
On Error Resume Next
Set o = CreateObject("foo.bar")
On Error Goto 0
If o Is Nothing Then
Response.Write "Oups, foo.bar isn't installed on this server!"
Else
Response.Write "Foo bar found, yay."
End If
This question already has a great answer but in the spirit of exploring all possibilities here is another technique to reorder dom elements whilst still allowing them to take up their space, unlike the absolute positioning method.
This method works in all modern browsers and IE9+ (basically any browser that supports display:table) it has a drawback that it can only be used on a max of 3 siblings though.
//the html
<div class='container'>
<div class='div1'>1</div>
<div class='div2'>2</div>
<div class='div3'>3</div>
</div>
//the css
.container {
display:table;
}
.div1 {
display:table-footer-group;
}
.div2 {
display:table-header-group;
}
.div3 {
display:table-row-group;
}
This will reorder the elements from 1,2,3 to 2,3,1. Basically anything with the display set to table-header-group will be positioned at the top and table-footer-group at the bottom. Naturally table-row-group puts an element in the middle.
This method is quick with good support and requires much less css than the flexbox approach so if you are only looking to swap a few items around for a mobile layout for example then dont rule out this technique.
You can check out a live demo on codepen: http://codepen.io/thepixelninja/pen/eZVgLx
Even though it can be done via immutability-helper or similar I do not wan't to add external dependencies to my code unless I really have to. When I need to do it I use Object.assign
. Code:
this.setState({ abc : Object.assign({}, this.state.abc , {xyz: 'new value'})})
Can be used on HTML Event Attributes as well, example:
onChange={e => this.setState({ abc : Object.assign({}, this.state.abc, {xyz : 'new value'})})}
If your host is using suPHP, you can try creating a php.ini
file in the same folder as the script and adding:
allow_url_fopen = On
(you can determine this by creating a file and checking which user it was created under: if you, it's suPHP, if "apache/nobody" or not you, then it's a normal PHP mode. You can also make a script
<?php
echo `id`;
?>
To give the same information, assuming shell_exec
is not a disabled function)
Just declare the enum outside the bounds of the class. Like this:
public enum card_suits
{
Clubs,
Hearts,
Spades,
Diamonds
}
public class Card
{
...
}
Remember that an enum is a type. You might also consider putting the enum in its own file if it's going to be used by other classes. (You're programming a card game and the suit is a very important attribute of the card that, in well-structured code, will need to be accessible by a number of classes.)
count of the contained lists in the outmost list
int count = data.size();
lambda to get the count of the contained inner lists
int count = data.stream().collect( summingInt(l -> l.size()) );
$query = "INSERT INTO myTable VALUES (NULL,'Fname', 'Lname', 'Website')";
Just leaving the value of the AI primary key NULL
will assign an auto incremented value.
CSS3 offers a way to do it with the @font-face rule.
http://www.w3.org/TR/css3-webfonts/#the-font-face-rule
http://www.css3.info/preview/web-fonts-with-font-face/
Here is a number of different ways which will work in browsers that don't support the @font-face rule.
.matches(".*\\d+.*")
only works for numbers but not other symbols like //
or *
etc.
If any of the above answers worked out, You can create new artifact directly from the admin side of (NEXUS Screen shot attached below).

- Then enter your groupid , artifact id and version .Now you will be able to add the corrsponding in your project.(screenshot below)
In addition to the top-answer, CSV files, for example, are reported as text/plain under macOS but as application/vnd.ms-excel under Windows. So I use this:
<input type="file" accept="text/plain, .csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel" />
I'd like to elaborate on Uliwitness answer, fixing his code for C++98 and using the Safe Bool idiom, for lack of the std::underlying_type<>
template and the explicit
keyword in C++ versions below C++11.
I also modified it so that the enum values can be sequential without any explicit assignment, so you can have
enum AnimalFlags_
{
HasClaws,
CanFly,
EatsFish,
Endangered
};
typedef FlagsEnum<AnimalFlags_> AnimalFlags;
seahawk.flags = AnimalFlags() | CanFly | EatsFish | Endangered;
You can then get the raw flags value with
seahawk.flags.value();
Here's the code.
template <typename EnumType, typename Underlying = int>
class FlagsEnum
{
typedef Underlying FlagsEnum::* RestrictedBool;
public:
FlagsEnum() : m_flags(Underlying()) {}
FlagsEnum(EnumType singleFlag):
m_flags(1 << singleFlag)
{}
FlagsEnum(const FlagsEnum& original):
m_flags(original.m_flags)
{}
FlagsEnum& operator |=(const FlagsEnum& f) {
m_flags |= f.m_flags;
return *this;
}
FlagsEnum& operator &=(const FlagsEnum& f) {
m_flags &= f.m_flags;
return *this;
}
friend FlagsEnum operator |(const FlagsEnum& f1, const FlagsEnum& f2) {
return FlagsEnum(f1) |= f2;
}
friend FlagsEnum operator &(const FlagsEnum& f1, const FlagsEnum& f2) {
return FlagsEnum(f1) &= f2;
}
FlagsEnum operator ~() const {
FlagsEnum result(*this);
result.m_flags = ~result.m_flags;
return result;
}
operator RestrictedBool() const {
return m_flags ? &FlagsEnum::m_flags : 0;
}
Underlying value() const {
return m_flags;
}
protected:
Underlying m_flags;
};
In your package.json
in the "dependencies"
section add moment:
"dependencies": {
"moment": "^2.15.2",
...
}
In the component where you would like to use moment, import it:
<script>
import moment from 'moment'
...
And in the same component add a computed property:
computed: {
timestamp: function () {
return moment(this.<model>.attributes['created-at']).format('YYYY-MM-DD [at] hh:mm')
}
}
And then in the template of this component:
<p>{{ timestamp }}</p>
You can use the following formula,
=IF(ISTEXT(REGEXEXTRACT(A1; "Bla")); "Yes";"No")
Red-Black trees:
git reset --hard HEAD^
Use the above command to revert merge changes.
The right answer (using Python 2.7 and later, since check_output()
was introduced then) is:
py2output = subprocess.check_output(['python','py2.py','-i', 'test.txt'])
To demonstrate, here are my two programs:
py2.py:
import sys
print sys.argv
py3.py:
import subprocess
py2output = subprocess.check_output(['python', 'py2.py', '-i', 'test.txt'])
print('py2 said:', py2output)
Running it:
$ python3 py3.py
py2 said: b"['py2.py', '-i', 'test.txt']\n"
Here's what's wrong with each of your versions:
py2output = subprocess.check_output([str('python py2.py '),'-i', 'test.txt'])
First, str('python py2.py')
is exactly the same thing as 'python py2.py'
—you're taking a str
, and calling str
to convert it to an str
. This makes the code harder to read, longer, and even slower, without adding any benefit.
More seriously, python py2.py
can't be a single argument, unless you're actually trying to run a program named, say, /usr/bin/python\ py2.py
. Which you're not; you're trying to run, say, /usr/bin/python
with first argument py2.py
. So, you need to make them separate elements in the list.
Your second version fixes that, but you're missing the '
before test.txt'
. This should give you a SyntaxError
, probably saying EOL while scanning string literal
.
Meanwhile, I'm not sure how you found documentation but couldn't find any examples with arguments. The very first example is:
>>> subprocess.check_output(["echo", "Hello World!"])
b'Hello World!\n'
That calls the "echo"
command with an additional argument, "Hello World!"
.
Also:
-i is a positional argument for argparse, test.txt is what the -i is
I'm pretty sure -i
is not a positional argument, but an optional argument. Otherwise, the second half of the sentence makes no sense.
$destroy
can refer to 2 things: method and event
.directive("colorTag", function(){
return {
restrict: "A",
scope: {
value: "=colorTag"
},
link: function (scope, element, attrs) {
var colors = new App.Colors();
element.css("background-color", stringToColor(scope.value));
element.css("color", contrastColor(scope.value));
// Destroy scope, because it's no longer needed.
scope.$destroy();
}
};
})
See @SunnyShah's answer.
Isn't this easier :
SELECT *
FROM tc_tariff_groups
GROUP BY group_id
HAVING COUNT(group_id) >1
?
An easy way I'm using:
file_put_contents($output_file, file_get_contents($base64_string));
This works well because file_get_contents
can read data from a URI, including a data:// URI.
this.form.submit();
This is probably your best bet. Especially if you are not already using jQuery in your project, there is no need to add it (or any other JS library) just for this purpose.
Actually what Luis proposed did not work for me. I had to figure out another way. This is what helped me. Might help you too. Links:
*.getEncoded(): https://docs.oracle.com/javase/7/docs/api/java/security/Key.html
Encoder information: https://docs.oracle.com/javase/8/docs/api/java/util/Base64.Encoder.html
Decoder information: https://docs.oracle.com/javase/8/docs/api/java/util/Base64.Decoder.html
Code snippets: For encoding:
String temp = new String(Base64.getEncoder().encode(key.getEncoded()));
For decoding:
byte[] encodedKey = Base64.getDecoder().decode(temp);
SecretKey originalKey = new SecretKeySpec(encodedKey, 0, encodedKey.length, "DES");
You can get the multiple element by id by identifying what element it is. For example
<div id='id'></div>
<div id='id'></div>
<div id='id'></div>
I assume if you are using jQuery you can select all them all by
$("div#id")
. This will get you array of elements you loop them based on your logic.
Here's how to do the same with Swift;
var valueToSave = "someValue"
NSUserDefaults.standardUserDefaults().setObject(valueToSave, forKey: "preferenceName")
To get it back later;
if let savedValue = NSUserDefaults.standardUserDefaults().stringForKey("preferenceName") {
// Do something with savedValue
}
In Swift 3.0
var valueToSave = "someValue"
UserDefaults.standard.set(valueToSave, forKey: "preferenceName")
if let savedValue = UserDefaults.standard.string(forKey: "preferenceName") {
}
In addition to all the answers above:
If you are on Android 6.0+ (API Level 23+) you have to explicitly ask for permission to access external storage. Simply having
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
in your manifest won't be enough. You also have actively request the permission in your activity:
//check for permission
if(ContextCompat.checkSelfPermission(this,
Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED){
//ask for permission
requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, READ_EXTERNAL_STORAGE_PERMISSION_CODE);
}
I recommend reading this: http://developer.android.com/training/permissions/requesting.html#perm-request
Path.GetDirectoryName()
... but you need to know that the path you are passing to it does contain a file name; it simply removes the final bit from the path, whether it is a file name or directory name (it actually has no idea which).
You could validate first by testing File.Exists()
and/or Directory.Exists()
on your path first to see if you need to call Path.GetDirectoryName

Use JContainer.Parse(str)
method to check if the str is a valid Json. If this throws exception then it is not a valid Json.
JObject.Parse
- Can be used to check if the string is a valid Json object
JArray.Parse
- Can be used to check if the string is a valid Json Array
JContainer.Parse
- Can be used to check for both Json object & Array
document.getElementById('link-id').href = "new-href";
I know this is an old post, but here's a one-liner that might be more suitable for some folks.
<strong>
and <em>
- unlike <b>
and <i>
- have clear purpose for web browsers for the blind.
A blind person doesn't browse the web visually, but by sound such as text readers. <strong>
and <em>
, in addition to encouraging something to be bold or italic, also convey loudness or stressing syllables respectively (OH MY! & Ooooooh Myyyyyyy!). Audio-only browsers are unpredictable when it comes to <b>
and <i>
... they may make them loud or stress them or they may not... you never can be sure unless you use <strong>
and <em>
.
And here, for those still not satisfied (like me), the original code from .NET-Frameworks GeoCoordinate
class, refactored into a standalone method:
public double GetDistance(double longitude, double latitude, double otherLongitude, double otherLatitude)
{
var d1 = latitude * (Math.PI / 180.0);
var num1 = longitude * (Math.PI / 180.0);
var d2 = otherLatitude * (Math.PI / 180.0);
var num2 = otherLongitude * (Math.PI / 180.0) - num1;
var d3 = Math.Pow(Math.Sin((d2 - d1) / 2.0), 2.0) + Math.Cos(d1) * Math.Cos(d2) * Math.Pow(Math.Sin(num2 / 2.0), 2.0);
return 6376500.0 * (2.0 * Math.Atan2(Math.Sqrt(d3), Math.Sqrt(1.0 - d3)));
}
If you are inside a batch script, you can use argument variable tricks to get the filesize:
filesize.bat:
@echo off
echo %~z1
This gives results like the ones you suggest in your question.
Type
help call
at the command prompt for all of the crazy variable manipulation options. Also see this article for more information.
Edit: This only works in Windows 2000 and later
var result = string.Join("", input.Select(c => ((int)c).ToString("X2")));
OR
var result =string.Join("",
input.Select(c=> String.Format("{0:X2}", Convert.ToInt32(c))));
First concatenate the two arrays, next filter out only the unique items:
var a = [1, 2, 3], b = [101, 2, 1, 10]_x000D_
var c = a.concat(b)_x000D_
var d = c.filter((item, pos) => c.indexOf(item) === pos)_x000D_
_x000D_
console.log(d) // d is [1, 2, 3, 101, 10]
_x000D_
As suggested a more performance wise solution would be to filter out the unique items in b
before concatenating with a
:
var a = [1, 2, 3], b = [101, 2, 1, 10]_x000D_
var c = a.concat(b.filter((item) => a.indexOf(item) < 0))_x000D_
_x000D_
console.log(c) // c is [1, 2, 3, 101, 10]
_x000D_
There are several things wrong with your script.
Functions (subroutines) should be declared before attempting to call them. You probably want to return() but not exit() from your subroutine to allow the calling block to test the success or failure of a particular command. That aside, you don't capture 'ERROR_CODE' so that is always zero (undefined).
It's good practice to surround your variable references with curly braces, too. Your code might look like:
#!/bin/sh
command="/bin/date -u" #...Example Only
safeRunCommand() {
cmnd="$@" #...insure whitespace passed and preserved
$cmnd
ERROR_CODE=$? #...so we have it for the command we want
if [ ${ERROR_CODE} != 0 ]; then
printf "Error when executing command: '${command}'\n"
exit ${ERROR_CODE} #...consider 'return()' here
fi
}
safeRunCommand $command
command="cp"
safeRunCommand $command
Create a folder named fonts in the assets folder and add the snippet from the below link.

But the problem with this code is that, I cannot change the content popup content from "Please enter your name" to my html form.
Umm. Just change the string passed to the prompt()

While searching, I found that there we CANNOT change the content of popup Prompt Box
You can't change the title. You can change the content, it is the first argument passed to the prompt()
function.
I had the same problem. After spending hours searching on the web, I found a solution for me.

You could use the random.sample
function from the standard library to select k elements from a population:
import random
random.sample(range(low, high), n)
In case of a rather large range of possible numbers, you could use itertools.islice
with an infinite random generator:
import itertools
import random
def random_gen(low, high):
while True:
yield random.randrange(low, high)
gen = random_gen(1, 100)
items = list(itertools.islice(gen, 10)) # Take first 10 random elements
After the question update it is now clear that you need n distinct (unique) numbers.
import itertools
import random
def random_gen(low, high):
while True:
yield random.randrange(low, high)
gen = random_gen(1, 100)
items = set()
# Try to add elem to set until set length is less than 10
for x in itertools.takewhile(lambda x: len(items) < 10, gen):
items.add(x)
One simple solution for this cab be like below
public class GenericDemo<T>{

GenericDemo(T t)
{
this.type = t;
}
public String getType()

return this.type.getClass().getName();
}
public static void main(String[] args)
{
GenericDemo<Integer> obj = new GenericDemo<Integer>(5);
System.out.println("Type: "+ obj.getType());
}
}
This should give you the commands printed out in separate lines:

map(lambda p:p, range(readline.get_current_history_length()))
)

None of the above, if you are on a Mac. Use Charles Proxy. It's the best network/request information collecter that I have ever come across. You can view and edit all outgoing requests, and see the responses from those requests in several forms, depending on the type of the response. It costs 50 dollars for a license, but you can download the trial version and see what you think.
If your on Windows, then I would just stay with Fiddler.

You can use Integer.parseInt(str)
and catch the NumberFormatException
if the string is not a valid integer, in the following fashion (as pointed out by all answers):
static boolean isInt(String s)
{
try
{ int i = Integer.parseInt(s); return true; }
catch(NumberFormatException er)
{ return false; }
}
However, note here that if the evaluated integer overflows, the same exception will be thrown. Your purpose was to find out whether or not, it was a valid integer. So its safer to make your own method to check for validity:
static boolean isInt(String s) // assuming integer is in decimal number system
{
for(int a=0;a<s.length();a++)
{
if(a==0 && s.charAt(a) == '-') continue;
if( !Character.isDigit(s.charAt(a)) ) return false;
}
return true;
}

Yes. Empty or incomplete headers or response body typically caused by broken connections or server side crash can cause 502 errors if accessed via a gateway or proxy.

As it says, it is ambiguous. Your array comparison returns a boolean array. Methods any() and all() reduce values over the array (either logical_or or logical_and). Moreover, you probably don't want to check for equality. You should replace your condition with:
np.allclose(A.dot(eig_vec[:,col]), eig_val[col] * eig_vec[:,col])
public void EndTask(string taskname)
{
string processName = taskname.Replace(".exe", "");
foreach (Process process in Process.GetProcessesByName(processName))
{
process.Kill();
}
}
//EndTask("notepad");
Summary: no matter if the name contains .exe, the process will end. You don't need to "leave off .exe from process name", It works 100%.
As nobody published a solution with CountDownLatch. What about:
public class Lockeable {

public void doAfterEvent(){
countDownLatch.await();
doSomething();
}
public void reportDetonatingEvent(){
countDownLatch.countDown();
}
}
The analytic and synthetic reasons were already mentioned. For newcomers there's a more significant incentive to stop using the dated mysql_ functions.
Contemporary database APIs are just easier to use.
It's mostly the bound parameters which can simplify code. And with excellent tutorials (as seen above) the transition to PDO isn't overly arduous.
Rewriting a larger code base at once however takes time. Raison d'être for this intermediate alternative:
Using <pdo_mysql.php> you can switch from the old mysql_ functions with minimal effort. It adds pdo_
function wrappers which replace their mysql_
counterparts.
Simply include_once(
"pdo_mysql.php"
);
in each invocation script that has to interact with the database.
Remove the function prefix everywhere and replace it with mysql_
pdo_
.
mysql_
connect()
becomes pdo_
connect()
mysql_
query()
becomes pdo_
query()
mysql_
num_rows()
becomes pdo_
num_rows()
mysql_
insert_id()
becomes pdo_
insert_id()
mysql_
fetch_array()
becomes pdo_
fetch_array()
mysql_
fetch_assoc()
becomes pdo_
fetch_assoc()
mysql_
real_escape_string()
becomes pdo_
real_escape_string()
Your code will work alike and still mostly look the same:
include_once("pdo_mysql.php");
pdo_connect("localhost", "usrABC", "pw1234567");
pdo_select_db("test");
$result = pdo_query("SELECT title, html FROM pages");
while ($row = pdo_fetch_assoc($result)) {
print "$row[title] - $row[html]";
}
Et voilà.
Your code is using PDO.
Now it's time to actually utilize it.
You just need a less unwieldy API.
pdo_query()
adds very facile support for bound parameters. Converting old code is straightforward:
Move your variables out of the SQL string.
pdo_query()
.?
as placeholders where the variables were before.'
single quotes that previously enclosed string values/variables.The advantage becomes more obvious for lengthier code.
Often string variables aren't just interpolated into SQL, but concatenated with escaping calls in between.
pdo_query("SELECT id, links, html, title, user, date FROM articles
WHERE title='" . pdo_real_escape_string($title) . "' OR id='".
pdo_real_escape_string($title) . "' AND user <> '" .
pdo_real_escape_string($root) . "' ORDER BY date")
With ?
placeholders applied you don't have to bother with that:
pdo_query("SELECT id, links, html, title, user, date FROM articles
WHERE title=? OR id=? AND user<>? ORDER BY date", $title, $id, $root)
Remember that pdo_* still allows either or.
Just don't escape a variable and bind it in the same query.
:named
placeholder lists later.More importantly you can pass $_REQUEST[] variables safely behind any query. When submitted <form>
fields match the database structure exactly it's even shorter:
pdo_query("INSERT INTO pages VALUES (?,?,?,?,?)", $_POST);
So much simplicity. But let's get back to some more rewriting advises and technical reasons on why you may want to get rid of and escaping.mysql_
sanitize()
functionOnce you have converted all calls to mysql_
pdo_query
with bound params, remove all redundant pdo_real_escape_string
calls.
In particular you should fix any sanitize
or clean
or filterThis
or clean_data
functions as advertised by dated tutorials in one form or the other:
function sanitize($str) {
return trim(strip_tags(htmlentities(pdo_real_escape_string($str))));
}
Most glaring bug here is the lack of documentation. More significantly the order of filtering was in exactly the wrong order.
Correct order would have been: deprecatedly stripslashes
as the innermost call, then trim
, afterwards strip_tags
, htmlentities
for output context, and only lastly the _escape_string
as its application should directly preceed the SQL intersparsing.
But as first step just get rid of the _real_escape_string
call.
You may have to keep the rest of your sanitize()
function for now if your database and application flow expect HTML-context-safe strings. Add a comment that it applies only HTML escaping henceforth.
String/value handling is delegated to PDO and its parameterized statements.
If there was any mention of stripslashes()
in your sanitize function, it may indicate a higher level oversight.
That was commonly there to undo damage (double escaping) from the deprecated magic_quotes
. Which however is best fixed centrally, not string by string.
Use one of the userland reversal approaches. Then remove the stripslashes()
in the sanitize
function.
Historic note on magic_quotes. That feature is rightly deprecated. It's often incorrectly portrayed as failed security feature however. But magic_quotes are as much a failed security feature as tennis balls have failed as nutrition source. That simply wasn't their purpose.
The original implementation in PHP2/FI introduced it explicitly with just "quotes will be automatically escaped making it easier to pass form data directly to msql queries". Notably it was accidentially safe to use with mSQL, as that supported ASCII only.
Then PHP3/Zend reintroduced magic_quotes for MySQL and misdocumented it. But originally it was just a convenience feature, not intend for security.
When you scramble string variables into the SQL queries, it doesn't just get more intricate for you to follow. It's also extraneous effort for MySQL to segregate code and data again.
SQL injections simply are when data bleeds into code context. A database server can't later spot where PHP originally glued variables inbetween query clauses.
With bound parameters you separate SQL code and SQL-context values in your PHP code. But it doesn't get shuffled up again behind the scenes (except with PDO::EMULATE_PREPARES). Your database receives the unvaried SQL commands and 1:1 variable values.
While this answer stresses that you should care about the readability advantages of dropping . There's occasionally also a performance advantage (repeated INSERTs with just differing values) due to this visible and technical data/code separation. mysql_
Beware that parameter binding still isn't a magic one-stop solution against all SQL injections. It handles the most common use for data/values. But can't whitelist column name / table identifiers, help with dynamic clause construction, or just plain array value lists.
These pdo_*
wrapper functions make a coding-friendly stop-gap API. (It's pretty much what MYSQLI
could have been if it wasn't for the idiosyncratic function signature shift). They also expose the real PDO at most times.
Rewriting doesn't have to stop at using the new pdo_ function names. You could one by one transition each pdo_query() into a plain $pdo->prepare()->execute() call.
It's best to start at simplifying again however. For example the common result fetching:
$result = pdo_query("SELECT * FROM tbl");
while ($row = pdo_fetch_assoc($result)) {
Can be replaced with just an foreach iteration:
foreach ($result as $row) {
Or better yet a direct and complete array retrieval:
$result->fetchAll();
You'll get more helpful warnings in most cases than PDO or mysql_ usually provide after failed queries.
So this hopefully visualized some practical reasons and a worthwile pathway to drop .mysql_
Just switching to pdo doesn't quite cut it. pdo_query()
is also just a frontend onto it.
Unless you also introduce parameter binding or can utilize something else from the nicer API, it's a pointless switch. I hope it's portrayed simple enough to not further the discouragement to newcomers. (Education usually works better than prohibition.)
While it qualifies for the simplest-thing-that-could-possibly-work category, it's also still very experimental code. I just wrote it over the weekend. There's a plethora of alternatives however. Just google for PHP database abstraction and browse a little. There always have been and will be lots of excellent libraries for such tasks.
If you want to simplify your database interaction further, mappers like Paris/Idiorm are worth a try. Just like nobody uses the bland DOM in JavaScript anymore, you don't have to babysit a raw database interface nowadays.
Notifications appear to have changed again (October 2016).
// Register to receive notification
NotificationCenter.default.addObserver(self, selector: #selector(yourClass.yourMethod), name: NSNotification.Name(rawValue: "yourNotificatioName"), object: nil)
// Post notification
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "yourNotificationName"), object: nil)
Instead of iterating through all the views or overriding dispatchTouchEvent.
Why Not just override the onUserInteraction() of the Activity this will make sure keyboard dismisses whenever the user taps outside of EditText.
Will work even when EditText is inside the scrollView.
@Override
public void onUserInteraction() {
if (getCurrentFocus() != null) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
}
}
The problem in my case was in the discrepancy between the Gradle version installed globally and the one required by React Native. To fix it, I had to update the folder android/gradle/wrapper
from the current 6.5 RN version from GH.
For that I have written the following code in the "ActionPeformed(...)" method of the "Start" button
You need that code to be in the actionPerformed(...)
of the ActionListener
registered with the Start button, not for the Start button itself.
You can add a simple ActionListener
like this:
JButton startButton = new JButton("Start");
startButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
startButton.setEnabled(false);
stopButton.setEnabled(true);
}
}
);
note that your startButton above will need to be final
in the above example if you want to create the anonymous listener in local scope.
First of all: you should always import mockito static, this way the code will be much more readable (and intuitive):
import static org.mockito.Mockito.*;
There are actually many ways to achieve this, however it's (arguably) cleaner to use the
verify(yourMock, times(0)).someMethod();
method all over your tests, when on other Tests you use it to assert a certain amount of executions like this:
verify(yourMock, times(5)).someMethod();
Alternatives are:
verify(yourMock, never()).someMethod();
Alternatively - when you really want to make sure a certain mocked Object is actually NOT called at all - you can use:
verifyZeroInteractions(yourMock)
From the MDN documentation:
[The margin property] applies to all elements except elements with table display types other than table-caption, table and inline-table
In other words, the margin
property is not applicable to display:table-cell
elements.
Consider using the border-spacing
property instead.
Note it should be applied to a parent element with a display:table
layout and border-collapse:separate
.
For example:
HTML
<div class="table">
<div class="row">
<div class="cell">123</div>
<div class="cell">456</div>
<div class="cell">879</div>
</div>
</div>
CSS
.table {display:table;border-collapse:separate;border-spacing:5px;}
.row {display:table-row;}
.cell {display:table-cell;padding:5px;border:1px solid black;}
Different margin horizontally and vertically
As mentioned by Diego Quirós, the border-spacing
property also accepts two values to set a different margin for the horizontal and vertical axes.
For example
.table {/*...*/border-spacing:3px 5px;} /* 3px horizontally, 5px vertically */
Normally virtualenv
creates environments in the current directory. Unless you're intending to create virtual environments in C:\Windows\system32
for some reason, I would use a different directory for environments.
You shouldn't need to mess with paths: use the activate
script (in <env>\Scripts
) to ensure that the Python executable and path are environment-specific. Once you've done this, the command prompt changes to indicate the environment. You can then just invoke easy_install and whatever you install this way will be installed into this environment. Use deactivate
to set everything back to how it was before activation.
Example:
c:\Temp>virtualenv myenv
New python executable in myenv\Scripts\python.exe
Installing setuptools..................done.
c:\Temp>myenv\Scripts\activate
(myenv) C:\Temp>deactivate
C:\Temp>
Notice how I didn't need to specify a path for deactivate
- activate
does that for you, so that when activated "Python" will run the Python in the virtualenv, not your system Python. (Try it - do an import sys; sys.prefix
and it should print the root of your environment.)
You can just activate a new environment to switch between environments/projects, but you'll need to specify the whole path for activate
so it knows which environment to activate. You shouldn't ever need to mess with PATH or PYTHONPATH explicitly.
If you use Windows Powershell then you can take advantage of a wrapper. On Linux, the virtualenvwrapper
(the link points to a port of this to Powershell) makes life with virtualenv
even easier.
Update: Not incorrect, exactly, but perhaps not quite in the spirit of virtualenv
. You could take a different tack: for example, if you install Django and anything else you need for your site in your virtualenv, then you could work in your project directory (where you're developing your site) with the virtualenv activated. Because it was activated, your Python would find Django and anything else you'd easy_installed into the virtual environment: and because you're working in your project directory, your project files would be visible to Python, too.
Further update: You should be able to use pip
, distribute
instead of setuptools
, and just plain python setup.py install
with virtualenv
. Just ensure you've activated an environment before installing something into it.
Suppose you want to install Laravel Collective. It's currently at version 6.x but you want version 5.8. You can run the following command:
composer require "laravelcollective/html":"^5.8.0"
A good example is shown here in the documentation: https://laravelcollective.com/docs/5.5/html
Some libraries attempt to offer alternatives to the builtin java switch
statement. Vavr is one of them, they generalize it to pattern matching.
Here is an example from their documentation:
String s = Match(i).of(
Case($(1), "one"),
Case($(2), "two"),
Case($(), "?")
);
You can use any predicate, but they offer many of them out of the box, and $(null)
is perfectly legal. I find this a more elegant solution than the alternatives, but this requires java8 and a dependency on the vavr library...

I believe that should do it
I guess you can use @CollectionOfElements
(for hibernate/jpa 1) / @ElementCollection
(jpa 2) to map a collection of "entity properties" to a List

.
You can create the EntityProperty

The biggest difference in my opinion
jQuery UI is fallback safe, it works correctly and looks good in old browsers, where Bootstrap is based on CSS3 which basically means GREAT in new browsers, not so great in old
Update frequency: Bootstrap is getting some great big updates with awesome new features, but sadly they might break previous code, so you can't just install bootstrap and update when there is a new major release, it basically requires a lot of new coding
jQuery UI is based on good html structure with transformations from JavaScript, while Bootstrap is based on visually and customizable inline structure. (calling a widget in JQUERY UI, defining it in Bootstrap)
So what to choose?
That always depends on the type of project you are working on. Is cool and fast looking widgets better, or are your users often using old browsers?
I always end up using both, so I can use the best of both worlds.
Here are the links to both frameworks, if you decide to use them.
This may work for you:
select t1.*
from table t1
join (select t2.Chromosome, t2.Locus
from table2
group by t2.Chromosome, t2.Locus
having count(*) > 1) u on u.Chromosome = t1.Chromosome and u.Locus = t1.Locus
I'm putting this in a new answer because no linebreaks / codeblocks in comments. I assume you want those nans to turn into a blank string? I couldn't find a nice way to do this, only do the ugly method:
s = pd.Series([1001.,1002.,None])
a = s.loc[s.isnull()].fillna('')
b = s.loc[s.notnull()].astype(int).astype(str)
result = pd.concat([a,b])
It will give you difference in months
long milliSeconds1 = calendar1.getTimeInMillis();
long milliSeconds2 = calendar2.getTimeInMillis();
long periodSeconds = (milliSeconds2 - milliSeconds1) / 1000;
long elapsedDays = periodSeconds / 60 / 60 / 24;
System.out.println(String.format("%d months", elapsedDays/30));
Like this:
var myString = "19 51 2.108997";
var stringParts = myString.split(" ");
var html = "<span>" + stringParts[0] + " " + stringParts[1] + "</span> <span>" + stringParts[2] + "</span";
A good example of real time found from here:-
A concrete example of an abstract class would be a class called Animal. You see many animals in real life, but there are only kinds of animals. That is, you never look at something purple and furry and say "that is an animal and there is no more specific way of defining it". Instead, you see a dog or a cat or a pig... all animals. The point is, that you can never see an animal walking around that isn't more specifically something else (duck, pig, etc.). The Animal is the abstract class and Duck/Pig/Cat are all classes that derive from that base class. Animals might provide a function called "Age" that adds 1 year of life to the animals. It might also provide an abstract method called "IsDead" that, when called, will tell you if the animal has died. Since IsDead is abstract, each animal must implement it. So, a Cat might decide it is dead after it reaches 14 years of age, but a Duck might decide it dies after 5 years of age. The abstract class Animal provides the Age function to all classes that derive from it, but each of those classes has to implement IsDead on their own.
A business example:
I have a persistance engine that will work against any data sourcer (XML, ASCII (delimited and fixed-length), various JDBC sources (Oracle, SQL, ODBC, etc.) I created a base, abstract class to provide common functionality in this persistance, but instantiate the appropriate "Port" (subclass) when persisting my objects. (This makes development of new "Ports" much easier, since most of the work is done in the superclasses; especially the various JDBC ones; since I not only do persistance but other things [like table generation], I have to provide the various differences for each database.) The best business examples of Interfaces are the Collections. I can work with a java.util.List without caring how it is implemented; having the List as an abstract class does not make sense because there are fundamental differences in how anArrayList works as opposed to a LinkedList. Likewise, Map and Set. And if I am just working with a group of objects and don't care if it's a List, Map, or Set, I can just use the Collection interface.

The term ‘fixed point’ refers to the corresponding manner in which numbers are represented, with a fixed number of digits after, and sometimes before, the decimal point. With floating-point representation, the placement of the decimal point can ‘float’ relative to the significant digits of the number. For example, a fixed-point representation with a uniform decimal point placement convention can represent the numbers 123.45, 1234.56, 12345.67, etc, whereas a floating-point representation could in addition represent 1.234567, 123456.7, 0.00001234567, 1234567000000000, etc.
If you just want the content as string
, then the simple solution is to use the ReadFile
function from the io/ioutil
package. This function returns a slice of bytes
which you can easily convert to a string
.
package main
import (
"fmt"
"io/ioutil"
)
func main() {
b, err := ioutil.ReadFile("file.txt") // just pass the file name
if err != nil {
fmt.Print(err)
}
fmt.Println(b) // print the content as 'bytes'
str := string(b) // convert content to a 'string'
fmt.Println(str) // print the content as a 'string'
}
You can creat the table you want, save it as an image and then use an image map to creat the link (this way you can put the coords of the hole td to make it in to a link).

Add the following style to your h3
elements:
word-wrap: break-word;
This will cause the long URLs in them to wrap. The default setting for word-wrap is normal
, which will wrap only at a limited set of split tokens (e.g. whitespaces, hyphens), which are not present in a URL.
You can use the window.innerWidth and window.innerHeight properties.
Since you seem to only have scalar values an PHP’s array is rather a hash map, you could use the value as key to avoid duplicates and associate the $k
keys to them to be able to get the original values:
$keys = array();
foreach ($array as $k => $v){
if (isset($v['key'])) {
$keys[$value] = $k;
}
}
Then you just need to iterate it to get the original values:
$unique = array();
foreach ($keys as $key) {
$unique[] = $array[$key]['key'];
}
This is probably not the most obvious and most comprehensive approach but it is very efficient as it is in O(n).
Using in_array
instead like others suggested is probably more intuitive. But you would end up with an algorithm in O(n2) (in_array
is in O(n)) that is not applicable. Even pushing all values in the array and using array_unique
on it would be better than in_array
(array_unique
sorts the values in O(n·log n) and then removes successive duplicates).

The V1 git man page had a reference about un-applying a stash. The excerpt is below.
The newer V2 git man page doesn't include any reference to un-applying a stash but the below still works well
Un-applying a Stash In some use case scenarios you might want to apply stashed changes, do some work, but then un-apply those changes that originally came from the stash. Git does not provide such a stash un-apply command, but it is possible to achieve the effect by simply retrieving the patch associated with a stash and applying it in reverse:
$ git stash show -p stash@{0} | git apply -R
Again, if you don’t specify a stash, Git assumes the most recent stash:
$ git stash show -p | git apply -R
You may want to create an alias and effectively add a stash-unapply command to your Git. For example:
$ git config --global alias.stash-unapply '!git stash show -p | git apply -R'
$ git stash apply
$ #... work work work
$ git stash-unapply

Yeah - that didn't help much. You're pretty close to the rail, so you put the car in park (kill
ing: SignalException
).
beep beep
Warning: Caught SignalException Exception.
Info: Logged Error - Continuing Process.
At the last second, you pull out the keys (kill -9
), and the car stops, you slam forward into the steering wheel (the airbag can't inflate because you didn't gracefully stop the program - you terminated it), and the computer in the back of your car slams into the seat in front of it. A half-full can of Coke spills over the papers. The groceries in the back are crushed, and most are covered in egg yolk and milk. The car needs serious repair and cleaning. (Data Loss)
Hopefully you have insurance (Backups). Oh yeah - because the airbag didn't inflate, you're probably hurt (getting fired, etc).
But wait! There's more reasons why you might want to use rescue Exception => e
!
Let's say you're that car, and you want to make sure the airbag inflates if the car is exceeding its safe stopping momentum.
begin
# do driving stuff
rescue Exception => e
self.airbags.inflate if self.exceeding_safe_stopping_momentum?
raise
end
Here's the exception to the rule: You can catch Exception
only if you re-raise the exception. So, a better rule is to never swallow Exception
, and always re-raise the error.
But adding rescue is both easy to forget in a language like Ruby, and putting a rescue statement right before re-raising an issue feels a little non-DRY. And you do not want to forget the raise
statement. And if you do, good luck trying to find that error.
Thankfully, Ruby is awesome, you can just use the ensure
keyword, which makes sure the code runs. The ensure
keyword will run the code no matter what - if an exception is thrown, if one isn't, the only exception being if the world ends (or other unlikely events).
begin
# do driving stuff
ensure
self.airbags.inflate if self.exceeding_safe_stopping_momentum?
end
Boom! And that code should run anyways. The only reason you should use rescue Exception => e
is if you need access to the exception, or if you only want code to run on an exception. And remember to re-raise the error. Every time.
Note: As @Niall pointed out, ensure always runs. This is good because sometimes your program can lie to you and not throw exceptions, even when issues occur. With critical tasks, like inflating airbags, you need to make sure it happens no matter what. Because of this, checking every time the car stops, whether an exception is thrown or not, is a good idea. Even though inflating airbags is a bit of an uncommon task in most programming contexts, this is actually pretty common with most cleanup tasks.
You can try anchoring it to the end of the string, something like \\[^\\]*$
. Though I'm not sure if one absolutely has to use regexp for the task.
on MacOS Mojave where I used brew install postgresql
to install, I found it here
/usr/local/var/postgres/postgresql.conf
I got this using the following sql command cited in this response here:
psql -U postgres -c 'SHOW config_file'
I had been facing a similar issue, unfortunately after implementing all the solutions above, I came to the following conclusion.
I wrote this simple scrolling js, that accounts for the offset caused due to the header and relocated the div about 125 pixels below. Please use it as you see fit.
The HTML
<div id="#anchor"></div> <!-- #anchor here is the anchor tag which is on your URL -->
The JavaScript
$(function() {
$('a[href*=#]:not([href=#])').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'')
&& location.hostname == this.hostname) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top - 125 //offsets for fixed header
}, 1000);
return false;
}
}
});
//Executed on page load with URL containing an anchor tag.
if($(location.href.split("#")[1])) {
var target = $('#'+location.href.split("#")[1]);
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top - 125 //offset height of header here too.
}, 1000);
return false;
}
}
});

In some cases, when opening a LNK file it is expecting the end of the application run.
In such cases it is better to use the following syntax (so you do not have to wait the end of the application):
START /B /I "MyTitleApp" "myshortcut.lnk"
To open a TXT file can be in the way already indicated (because notepad.exxe not interrupt the execution of the start command)
START notepad "myfile.txt"
Normally when you try to select a node using xpath your xpath-engine will return null or equivalent if the node doesn't exists.

If your using xsl check out this question for an answer:
In the end, double-hashing, mathematically, provides no benefit. In practice, however, it is useful for preventing rainbow table-based attacks. In other words, it is of no more benefit than hashing with a salt, which takes far less processor time in your application or on your server.
Just putting it out there..... docs: https://laravel.com/docs/7.x/requests
I had this concern when working on a Rails application with Docker.
My most preferred approach is to generally not use quotes. This includes not using quotes for:
${RAILS_ENV}
postgres-log:/var/log/postgresql
I, however, use double-quotes for integer
values that need to be converted to strings like:
version: "3.8"
"8080:8080"
However, for special cases like booleans
, floats
, integers
, and other cases, where using double-quotes for the entry values could be interpreted as strings
, please do not use double-quotes.
Here's a sample docker-compose.yml
file to explain this concept:
version: "3"
services:
traefik:
image: traefik:v2.2.1
command:
- --api.insecure=true # Don't do that in production
- --providers.docker=true
- --providers.docker.exposedbydefault=false
- --entrypoints.web.address=:80
ports:
- "80:80"
- "8080:8080"
volumes:
- /var/run/docker.sock:/var/run/docker.sock:ro
That's all.
I hope this helps
you can refresh your fragment when it is visible to user, just add this code into your Fragment this will refresh your fragment when it is visible.
@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser) {
// Refresh your fragment here
getFragmentManager().beginTransaction().detach(this).attach(this).commit();
Log.i("IsRefresh", "Yes");

EDIT: According to the comments on the original post this is a C# question.
Short answer: yes, using the this
keyword.
Long answer: yes, using the this
keyword, and here's an example.
class MyClass
{
private object someData;
public MyClass(object data)
{
this.someData = data;
}
public MyClass() : this(new object())
{
// Calls the previous constructor with a new object,
// setting someData to that object
}
}

Instead of using Bitmap
, you can also do this through a trivial InputStream
. Well, I am not sure, but I think it's a bit efficient.
InputStream inputStream = new FileInputStream(fileName); // You can get an inputStream using any I/O API
byte[] bytes;
byte[] buffer = new byte[8192];
int bytesRead;
ByteArrayOutputStream output = new ByteArrayOutputStream();
try {
while ((bytesRead = inputStream.read(buffer)) != -1) {
output.write(buffer, 0, bytesRead);
}
}
catch (IOException e) {
e.printStackTrace();
}
bytes = output.toByteArray();
String encodedString = Base64.encodeToString(bytes, Base64.DEFAULT);
This is a modified version of Simons answer which makes the multi-lined output a single line. It also introduces the current timestamp so it's easier to follow each line of output.

I used the above to catch slow responses on the above endpoint.
Abstract methods means there is no default implementation for it and an implementing class will provide the details.
Essentially, you would have
abstract class AbstractObject {
public abstract void method();
}
class ImplementingObject extends AbstractObject {
public void method() {
doSomething();
}
}
So, it's exactly as the error states: your abstract method can not have a body.
There's a full tutorial on Oracle's site at: http://download.oracle.com/javase/tutorial/java/IandI/abstract.html
The reason you would do something like this is if multiple objects can share some behavior, but not all behavior.
A very simple example would be shapes:
You can have a generic graphic object, which knows how to reposition itself, but the implementing classes will actually draw themselves.
(This is taken from the site I linked above)
abstract class GraphicObject {
int x, y;
...
void moveTo(int newX, int newY) {
...
}
abstract void draw();
abstract void resize();
}
class Circle extends GraphicObject {
void draw() {
...
}
void resize() {
...
}
}
class Rectangle extends GraphicObject {
void draw() {
...
}
void resize() {
...
}
}
If you're using .NET 4.5 you can use the new async/await framework to sleep without locking the thread.
How it works is that you mark the function in need of asynchronous operations, with the async
keyword. This is just a hint to the compiler. Then you use the await
keyword on the line where you want your code to run asynchronously and your program will wait without locking the thread or the UI. The method you call (on the await line) has to be marked with an async
keyword as well and is usually named ending with Async, as in ImportFilesAsync.
What you need to do in your example is:
async
keyword (see example below)using System.Threading.Tasks;
to your code.Your code is now ready to use the Task.Delay
method instead of the System.Threading.Thread.Sleep
method (it is possible to use await
on Task.Delay
because Task.Delay
is marked with async
in its definition).
private async void button1_Click(object sender, EventArgs e)
{
textBox1.Text += "\r\nThread Sleeps!";
await Task.Delay(3000);
textBox1.Text += "\r\nThread awakens!";
}
Here you can read more about Task.Delay and Await.
I believe that you are looking for the java.lang.BigDecimal class.
You can use following code to read file in String from resource folder.
final Resource resource = new ClassPathResource("public.key");
String publicKey = null;
try {
publicKey = new String(Files.readAllBytes(resource.getFile().toPath()), StandardCharsets.UTF_8);
} catch (IOException e) {
e.printStackTrace();
}
This one worked for me
Private Sub TextBox1_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
If KeyCode = 13 Then
Button1_Click
End If
End Sub
Try this
new_df = pd.merge(A_df, B_df, how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])
https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.merge.html
left_on : label or list, or array-like Field names to join on in left DataFrame. Can be a vector or list of vectors of the length of the DataFrame to use a particular vector as the join key instead of columns
right_on : label or list, or array-like Field names to join on in right DataFrame or vector/list of vectors per left_on docs
simple and best way to use date function
example
SELECT * FROM
data
WHERE date(datetime) = '2009-10-20'
OR
SELECT * FROM
data
WHERE date(datetime ) >= '2009-10-20' && date(datetime ) <= '2009-10-20'
To join Array1 and Array2, create a new array say JointArray
Dim JointArray As Variant
ReDim JointArray(UBound(Array1) + UBound(Array2) + 1) As Variant
For i = 0 To UBound(JointArray)
If i <= UBound(Array1) Then
JointArray(i) = Array1(i)
Else
JointArray(i) = Array2(i - UBound(Array1) - 1)
End If
Next
('long text to be truncated').replace(/(.{250})..+/, "$1…");
Somehow above code was not working for some kind of copy pasted or written text in vuejs app. So I used lodash truncate and its now working fine.
_.truncate('long text to be truncated', { 'length': 250, 'separator': ' '});
Use permission symbols instead of numbers
Your problem would have been avoided if you had used the more semantically named permission symbols rather than raw magic numbers, e.g. for 664
:
#!/usr/bin/env python3
import os
import stat
os.chmod(
'myfile',
stat.S_IRUSR |
stat.S_IWUSR |
stat.S_IRGRP |
stat.S_IWGRP |
stat.S_IROTH
)
This is documented at https://docs.python.org/3/library/os.html#os.chmod and the names are the same as the POSIX C API values documented at man 2 stat
.
Another advantage is the greater portability as mentioned in the docs:
Note: Although Windows supports
chmod()
, you can only set the file’s read-only flag with it (via thestat.S_IWRITE
andstat.S_IREAD
constants or a corresponding integer value). All other bits are ignored.
chmod +x
is demonstrated at: How do you do a simple "chmod +x" from within python?
Tested in Ubuntu 16.04, Python 3.5.2.
Problem is that check weather you have closed all the streams or not if opened close the streams and delete,rename..etc the file this is worked for me
If you can move to SQL Server 2008, you can take advantage of the FILESTREAM support which gives you the best of both - the files are stored in the filesystem, but the database integration is much better than just storing a filepath in a varchar field. Your query can return a standard .NET file stream, which makes the integration a lot simpler.
Open SQL Server Management Studio > File > Open > File > Choose your .sql file (the one that contains your script) > Press Open > the file will be opened within SQL Server Management Studio, Now all what you need to do is to press Execute button.
In addition to the solution you accepted, you could also implement the special __lt__()
("less than") method on the class. The sort()
method (and the sorted()
function) will then be able to compare the objects, and thereby sort them. This works best when you will only ever sort them on this attribute, however.
class Foo(object):
def __init__(self, score):
self.score = score
def __lt__(self, other):
return self.score < other.score
l = [Foo(3), Foo(1), Foo(2)]
l.sort()
With adb, you can install GApps and ARM Support zips without a drag & drop. emuking from XDA Developers has instructions for it:
I used 4.2.2, which is acceptable for my testing purposes. I then extracted both zip's "/system/..." folders to a folder on my desktop. In cmd prompt I used the following commands (step 1 is optional and for verification that adb is working):
You'll have to change the folder name in "adb push" line to where you actually extracted both zip files. After doing it, I recommend you to "adb reboot" the device.
1) Your existing web.config: you have declared rewrite map .. but have not created any rules that will use it. RewriteMap on its' own does absolutely nothing.
2) Below is how you can do it (it does not utilise rewrite maps -- rules only, which is fine for small amount of rewrites/redirects):
This rule will do SINGLE EXACT rewrite (internal redirect) /page
to /page.html
. URL in browser will remain unchanged.
<system.webServer>
<rewrite>
<rules>
<rule name="SpecificRewrite" stopProcessing="true">
<match url="^page$" />
<action type="Rewrite" url="/page.html" />
</rule>
</rules>
</rewrite>
</system.webServer>
This rule #2 will do the same as above, but will do 301 redirect (Permanent Redirect) where URL will change in browser.
<system.webServer>
<rewrite>
<rules>
<rule name="SpecificRedirect" stopProcessing="true">
<match url="^page$" />
<action type="Redirect" url="/page.html" />
</rule>
</rules>
</rewrite>
</system.webServer>
Rule #3 will attempt to execute such rewrite for ANY URL if there are such file with .html extension (i.e. for /page
it will check if /page.html
exists, and if it does then rewrite occurs):
<system.webServer>
<rewrite>
<rules>
<rule name="DynamicRewrite" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{REQUEST_FILENAME}\.html" matchType="IsFile" />
</conditions>
<action type="Rewrite" url="/{R:1}.html" />
</rule>
</rules>
</rewrite>
</system.webServer>
for me, my problem was because of iptables-services was not installed, this worked for me (CentOS):
sudo yum install iptables-services
sudo service docker restart
i := 23
i64 := int64(i)
fmt.Printf("%T %T", i, i64) // to print the data types of i and i64
If this error happens in an UPDATE
, double-check the JOIN
on the table with the column/field that is causing the error.
In my case this was due to the lack of the JOIN
itself, which generated the same error due to an unknown field (as Andriy pointed out).
The __repr__ method simply tells Python how to print objects of a class
You should not play with the height. Let the text field determine the height based on the font used.
If you want to control the width of the text field then you can use
textField.setColumns(...);
to let the text field determine the preferred width.
Or if you want the width to be the entire width of the parent panel then you need to use an appropriate layout. Maybe the NORTH of a BorderLayout.
See the Swing tutorial on Layout Managers for more information.
For a vertically or horizontally scrollable TextView some of the other answers help, but I needed to be able to scroll both ways.
What finally worked is a ScrollView with a HorizontalScrollView inside of it, and a TextView inside the HSV. It's very smooth and can easily go side to side or top to bottom in one swipe. It also only allows scrolling in one direction at a time so there's none of the jumping side to side while scrolling up or down.
An EditText with editing and cursor disabled works, but it feels terrible. Each attempt to scroll moves the cursor and it requires many swipes to go top to bottom or side to side in even a ~100-line file.
Using setHorizontallyScrolling(true)
can work, but there's no similar method to allow vertical scrolling, and it doesn't work inside of a ScrollView as far as I can tell (just learning though, could be wrong).

var trans = Components.classes["@mozilla.org/widget/transferable;1"].createInstance(Components.interfaces.nsITransferable);
if (!trans) return;
// specify the data we wish to handle. Plaintext in this case.
trans.addDataFlavor('text/unicode');
// To get the data from the transferable we need two new objects
var str = new Object();
var len = new Object();
var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);
str.data= s;
trans.setTransferData("text/unicode",str, str.data.length * 2);
var clipid=Components.interfaces.nsIClipboard;
if (!clip) return false;
clip.setData(trans,null,clipid.kGlobalClipboard);
}
}
Unfortunately, it seems that Git has no such command built in. But you can easily add it yourself with Git aliases and some shell magic.
As pointed out by this answer, you can use git rev-parse --show-toplevel
to show the root of your current Git folder.
If you want to use this regularly, it's probably more convenient to define it as an alias. For this, used git config alias.root '!echo "$(git rev-parse --show-toplevel)"'
. After this, you can use git root
to see the root folder of the repository you're currently in.
If you want to use another subcommand name than root
, simply replace the second part of alias.root
in the above command with whatever you want.
For details on aliases in Git, see also the git config
man page.
Decoding is redundant
You only had this "error" in the first place, because of a misunderstanding of what's happening.
You get the b
because you encoded to utf-8
and now it's a bytes object.
>> type("text".encode("utf-8"))
>> <class 'bytes'>
Fixes:
Take a look at Rick Hightower's approach. His approach avoids configuring ObjectMapper as a singleton and allows you to filter the JSON response for the same object in different ways per each request method.

From the official JAR File Specification (link goes to the Java 7 version, but the text hasn't changed since at least v1.3):
The META-INF directory
The following files/directories in the META-INF directory are recognized and interpreted by the Java 2 Platform to configure applications, extensions, class loaders and services:
MANIFEST.MF
The manifest file that is used to define extension and package related data.
INDEX.LIST
This file is generated by the new "
-i
" option of the jar tool, which contains location information for packages defined in an application or extension. It is part of the JarIndex implementation and used by class loaders to speed up their class loading process.
x.SF
The signature file for the JAR file. 'x' stands for the base file name.
x.DSA
The signature block file associated with the signature file with the same base file name. This file stores the digital signature of the corresponding signature file.
services/
This directory stores all the service provider configuration files.
I will say what worked for me, the others answers above didn't help to my case at all. I hope it can help someone.
Actually, I'm using Virtual host configuration (sites-available / sites-enabled) on EC2 Linux AMI with Apache/2.4.39 (Amazon). So, I have 1 ec2 instance to serve many sites (domains).
Considering that you already have Virtual Host installed and working. In my folder /etc/httpd/sites-available, I have some files with domain names (suffix .conf), for example: domain.com.conf. Create a new file like that.
sudo nano /etc/httpd/sites-available/domain.com.conf
<VirtualHost *:80>
ServerName www.domain.com
ServerAlias domain.com
DocumentRoot /var/www/html/domain
</VirtualHost>
For each file.conf in sites-available, I create a symbolic link:
sudo ln -s /etc/httpd/sites-available/domain.com.conf /etc/httpd/sites-enabled/domain.com.conf
This is the default configuration, so, if access directly by IP of Server, you will be redirect to DocumentRoot of the first file (.conf) in sites-available folder, sorted by filename.
To have a default DocumentRoot folder when access by IP, you have to create a file named 0a.conf, then apache will serve this site because this new file will be the first in sites-available folder.
You must create a symbolic link:
sudo ln -s /etc/httpd/sites-available/0a.conf /etc/httpd/sites-enabled/0a.conf
To check serving order, use it:
sudo apachectl -S
Now, restart apache, and check out it.
Be happy =)
that scp command must be issued on the local command-line, for putty the command is pscp.
C:\something> pscp [email protected]:/dir/of/file.txt \local\dir\
Like others have mentioned, you probably want to look at reusing an existing graphing solution, but rotating text isn't too difficult. The somewhat confusing bit (to me) is that you rotate the whole context and then draw on it:
ctx.rotate(Math.PI*2/(i*6));
The angle is in radians. The code is taken from this example, which I believe was made for the transformations part of the MDC canvas tutorial.

in case jquery sucks
That error message usually means that either the password we are using doesn't match what MySQL thinks the password should be for the user we're connecting as, or a matching MySQL user doesn't exist (hasn't been created).
In MySQL, a user is identified by both a username ("test2") and a host ("localhost").
The error message identifies the user ("test2") and the host ("localhost") values...
'test2'@'localhost'
We can check to see if the user exists, using this query from a client we can connect from:
SELECT user, host FROM mysql.user
We're looking for a row that has "test2" for user, and "localhost" for host.
user host
------- -----------
test2 127.0.0.1 cleanup
test2 ::1
test2 localhost
If that row doesn't exist, then the host may be set to wildcard value of %
, to match any other host that isn't a match.
If the row exists, then the password may not match. We can change the password (if we're connected as a user with sufficient privileges, e.g. root
SET PASSWORD FOR 'test2'@'localhost' = PASSWORD('mysecretcleartextpassword')
We can also verify that the user has privileges on objects in the database.
GRANT SELECT ON jobs.* TO 'test2'@'localhost'
EDIT
If we make changes to mysql privilege tables with DML operations (INSERT,UPDATE,DELETE), those changes will not take effect until MySQL re-reads the tables. We can make changes effective by forcing a re-read with a FLUSH PRIVILEGES
statement, executed by a privileged user.
In my case, turned out that you need to be logged as owner of device to properly accept the USB debugging.
Tried the "Disable and re-enable USB debugging on the phone" step but didn't get the RSA prompt on "normal" user, switched to owner and tried again and got it.
Aligning text in native markdown is not possible. However, you can align the text using inline HTML tags.
<div style="text-align: right"> your-text-here </div>
To justify, replace right

Haven't you heard about the Comparable

"abcda".compareTo("abcza")
And it will output a good root for a solution to your problem.
Global variables are not extern
nor static
by default on C and C++.
When you declare a variable as static
, you are restricting it to the current source file. If you declare it as extern
, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern
keyword) you will get a link error (symbol not found).
Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal
. If you declare it as static
, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal
.
What you can do in C++, that you can't in C, is to declare the variable as const
on the header, like this:
const int varGlobal = 7;
And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define
for constants.
If you need a global variable visible on multiple sources and not const
, declare it as extern
on the header, and then define it, this time without the extern keyword, on a source file:
Header included by multiple files:
extern int varGlobal;
In one of your source files:
int varGlobal = 7;
<form action="#">
<input type="text" id="txtBox" name="txt" onkeypress="handle" />
</form>
<script>
$("#txtBox").keypress(function (e) {
if (e.keyCode === 13) {
alert("Enter was pressed was presses");
}
return false;
});
</script>
The best move is to just nest a flexbox inside of a flexbox. All you have to do is give the child align-items: center
. This will vertically align the text inside of its parent.
// Assuming a horizontally centered row of items for the parent but it doesn't have to be
.parent {
align-items: center;
display: flex;
justify-content: center;
}
.child {
display: flex;
align-items: center;
}
I used this:
$('.nav-list li.active').removeClass('active');
$(this).parent().addClass('active');
Since the active class is in the <li>
element and what is clicked is the <a>
element, the first line removes .active
from all <li>
and the second one (again, $(this)
represents <a>
which is the clicked element) adds .active
to the direct parent, which is <li>
.
Try this code, works 100% for me:
FOR Landscape:

<style type="text/css">
@page{
size: auto A4 landscape;
margin: 3mm;
}

</head>
FOR Portait:
<head>
<style type="text/css">
@page{
size: auto;
margin: 3mm;
}
</style>

The text below comes from Comparator vs Comparable
Comparable
A comparable object is capable of comparing itself with another object. The class itself must implements the java.lang.Comparable
interface in order to be able to compare its instances.
Comparator
A comparator object is capable of comparing two different objects. The class is not comparing its instances, but some other class’s instances. This comparator class must implement the java.util.Comparator
interface.

Try this:
String[] trimmedArray = new String[array.length];
for (int i = 0; i < array.length; i++)
trimmedArray[i] = array[i].trim();
Now trimmedArray
contains the same strings as array
, but without leading and trailing whitespace. Alternatively, you could write this for modifying the strings in-place in the same array:
for (int i = 0; i < array.length; i++)
array[i] = array[i].trim();
Besides the fact that the branch prediction may slow you down, a sorted array has another advantage:
You can have a stop condition instead of just checking the value, this way you only loop over the relevant data, and ignore the rest.
The branch prediction will miss only once.
// sort backwards (higher values first), may be in some other part of the code
std::sort(data, data + arraySize, std::greater<int>());
for (unsigned c = 0; c < arraySize; ++c) {
if (data[c] < 128) {
break;
}
sum += data[c];
}

You can explicitly specify the return type of a lambda by using -> Type
after the arguments list:
[]() -> Type { }
However, if a lambda has one statement and that statement is a return statement (and it returns an expression), the compiler can deduce the return type from the type of that one returned expression. You have multiple statements in your lambda, so it doesn't deduce the type.
Add an = at the beginning. That makes it a function rather than an entry.
The request was to format a date in this format:
Fri Aug 30 2013 4:36 pm
I strongly suggest that anyone who comes across this question should use JavaScript's Intl
API to format your dates instead of trying to come up with your own preferred format.
Here's an example
let d = new Date();
let formatter = Intl.DateTimeFormat(
"default", // a locale name; "default" chooses automatically
{
weekday: "short",
year: "numeric",
month: "short",
day: "numeric",
hour: "numeric",
minute: "numeric"
}
);
console.log(formatter.format(d));
_x000D_
The output for me, in the en-US locale, is:
Wed, Sep 30, 2020, 5:04 PM
The output for someone in Mexico (es-MX), is:
mié., 30 de septiembre de 2020 17:23
Intl
better?Intl
formats dates as appropriate for the user's locale, e.g. a user in a different country who would prefer to read the year before the month would see the appropriately formatted dateThis is working for me. Which version of Flask are you using?
from flask import jsonify

According to: https://docs.npmjs.com/files/folders
- Local install (default): puts stuff in ./node_modules of the current package root.
- Global install (with -g): puts stuff in /usr/local or wherever node is installed.
- Install it locally if you're going to require() it.
- Install it globally if you're going to run it on the command line. -> If you need both, then install it in both places, or use npm link.
prefix Configuration
The prefix config defaults to the location where node is installed. On most systems, this is
/usr/local
. On windows, this is the exact location of the node.exe binary.
The docs might be a little outdated, but they explain why global installs can end up in different directories:
(dev) go|c:\srv> npm config ls -l | grep prefix
; prefix = "C:\\Program Files\\nodejs" (overridden)
prefix = "C:\\Users\\bjorn\\AppData\\Roaming\\npm"
Based on the other answers, it may seem like the override is now the default location on Windows, and that I may have installed my office version prior to this override being implemented.
This also suggests a solution for getting all team members to have globals stored in the same absolute path relative to their PC, i.e. (run as Administrator):
mkdir %PROGRAMDATA%\npm
setx PATH "%PROGRAMDATA%\npm;%PATH%" /M
npm config set prefix %PROGRAMDATA%\npm
open a new cmd.exe window and reinstall all global packages.
Explanation (by lineno.):
setx .. /M
to set the
system path (under HKEY_LOCAL_MACHINE). This is what requires you to run
this in a shell with administrator permissions.npm
to use this new path. (Note: folder isn't visible in %PATH% in
this shell, so you must open a new window).In Java, all non-static methods are by default "virtual functions." Only methods marked with the keyword final, which cannot be overridden, along with private methods, which are not inherited, are non-virtual.
Try
$(".text").text(data);
Or to convert the data received to a string.
At its most basic, concatenating files from a batch file is done with 'copy'.
copy file1.txt + file2.txt + file3.txt concattedfile.txt
I don't think preg_replace is the answer.. old thread but just happen to looking for this today. ltrim and (int) casting is the winner.

$fixed_str2 = ltrim($numString, '0');
$fixed_str3 = (int)$numString;
echo $numString . " Original";
echo "<br>";
echo $fixed_str1 . " Fix1";
echo "<br>";
echo $fixed_str2 . " Fix2";
echo "<br>";
echo $fixed_str3 . " Fix3";
echo "<br>";

Not sure what you call FIFO these days since Queue is FILO, but when I was a student we used the Stack<E>

Python 2
The error is caused because ElementTree did not expect to find non-ASCII strings set the XML when trying to write it out. You should use Unicode strings for non-ASCII instead. Unicode strings can be made either by using the u
prefix on strings, i.e. u'€'
or by decoding a string with mystr.decode('utf-8')
using the appropriate encoding.
The best practice is to decode all text data as it's read, rather than decoding mid-program. The io
module provides an open()
method which decodes text data to Unicode strings as it's read.
ElementTree will be much happier with Unicodes and will properly encode it correctly when using the ET.write()
method.
Also, for best compatibility and readability, ensure that ET encodes to UTF-8 during write()
and adds the relevant header.
Presuming your input file is UTF-8 encoded (0xC2
is common UTF-8 lead byte), putting everything together, and using the with
statement, your code should look like:
with io.open('myText.txt', "r", encoding='utf-8') as f:
data = f.read()
root = ET.Element("add")
doc = ET.SubElement(root, "doc")
field = ET.SubElement(doc, "field")
field.set("name", "text")
field.text = data
tree = ET.ElementTree(root)
tree.write("output.xml", encoding='utf-8', xml_declaration=True)
Output:
<?xml version='1.0' encoding='utf-8'?>
<add><doc><field name="text">data€</field></doc></add>
Update: ASP.NET Core does not have a SynchronizationContext
. If you are on ASP.NET Core, it does not matter whether you use ConfigureAwait(false)
or not.
For ASP.NET "Full" or "Classic" or whatever, the rest of this answer still applies.
Original post (for non-Core ASP.NET):
This video by the ASP.NET team has the best information on using async
on ASP.NET.
I had read that it is more performant since it doesn't have to switch thread contexts back to the original thread context.
This is true with UI applications, where there is only one UI thread that you have to "sync" back to.
In ASP.NET, the situation is a bit more complex. When an async
method resumes execution, it grabs a thread from the ASP.NET thread pool. If you disable the context capture using ConfigureAwait(false)
, then the thread just continues executing the method directly. If you do not disable the context capture, then the thread will re-enter the request context and then continue to execute the method.
So ConfigureAwait(false)
does not save you a thread jump in ASP.NET; it does save you the re-entering of the request context, but this is normally very fast. ConfigureAwait(false)
could be useful if you're trying to do a small amount of parallel processing of a request, but really TPL is a better fit for most of those scenarios.
However, with ASP.NET Web Api, if your request is coming in on one thread, and you await some function and call ConfigureAwait(false) that could potentially put you on a different thread when you are returning the final result of your ApiController function.
Actually, just doing an await
can do that. Once your async
method hits an await
, the method is blocked but the thread returns to the thread pool. When the method is ready to continue, any thread is snatched from the thread pool and used to resume the method.
The only difference ConfigureAwait
makes in ASP.NET is whether that thread enters the request context when resuming the method.
I have more background information in my MSDN article on SynchronizationContext
and my async
intro blog post.
Very late answer, but this is how you could handle it with prototypes.
Array.prototype.Any = function(func) {
return this.some(func || function(x) { return x });
}
Object.prototype.IsAny = function() {
return Object.keys(this).Any();
}

If using a third party library is an option, there is jOOU (a spin off library from jOOQ), which offers wrapper types for unsigned integer numbers in Java. That's not exactly the same thing as having primitive type (and thus byte code) support for unsigned types, but perhaps it's still good enough for your use-case.
import static org.joou.Unsigned.*;
// and then...
UByte b = ubyte(1);
UShort s = ushort(1);
UInteger i = uint(1);
ULong l = ulong(1);
All of these types extend java.lang.Number
and can be converted into higher-order primitive types and BigInteger
.
(Disclaimer: I work for the company behind these libraries)
PL/SQL: numeric or value error: character string buffer too small
is due to the fact that you declare a string to be of a fixed length (say 20), and at some point in your code you assign it a value whose length exceeds what you declared.
for example:
myString VARCHAR2(20);
myString :='abcdefghijklmnopqrstuvwxyz'; --length 26
will fire such an error
This problem is commonly related to compiler errors in the Java code. Sometimes Android Studio does not show these errors in the Project explorer
. However, when a problematic .java
file is opened, errors are shown. Try to resolve errors and rebuild the project.
JohannesD's answer is correct, but I feel it isn't entirely clear on an aspect of the problem.
The example he gives declares and initializes the variable i
in case 1, and then tries to use it in case 2. His argument is that if the switch went straight to case 2, i
would be used without being initialized, and this is why there's a compilation error. At this point, one could think that there would be no problem if variables declared in a case were never used in other cases. For example:
switch(choice) {
case 1:
int i = 10; // i is never used outside of this case
printf("i = %d\n", i);
break;
case 2:
int j = 20; // j is never used outside of this case
printf("j = %d\n", j);
break;
}
One could expect this program to compile, since both i
and j
are used only inside the cases that declare them. Unfortunately, in C++ it doesn't compile: as Ciro Santilli ???? ???? ??? explained, we simply can't jump to case 2:
, because this would skip the declaration with initialization of i
, and even though case 2
doesn't use i
at all, this is still forbidden in C++.
Interestingly, with some adjustments (an #ifdef
to #include
the appropriate header, and a semicolon after the labels, because labels can only be followed by statements, and declarations do not count as statements in C), this program does compile as C:
// Disable warning issued by MSVC about scanf being deprecated
#ifdef _MSC_VER
#define _CRT_SECURE_NO_WARNINGS
#endif
#ifdef __cplusplus
#include <cstdio>
#else
#include <stdio.h>
#endif
int main() {
int choice;
printf("Please enter 1 or 2: ");
scanf("%d", &choice);
switch(choice) {
case 1:
;
int i = 10; // i is never used outside of this case
printf("i = %d\n", i);
break;
case 2:
;
int j = 20; // j is never used outside of this case
printf("j = %d\n", j);
break;
}
}
Thanks to an online compiler like http://rextester.com you can quickly try to compile it either as C or C++, using MSVC, GCC or Clang. As C it always works (just remember to set STDIN!), as C++ no compiler accepts it.
I know it's an old question but...
Some phones nowadays have a setting to utilize 2G only. It's perfect for simulating slow internet on a real device.
As of Ansible 2.0 there seems to be an option called strategy
on a playbook. When setting the strategy to free
, the playbook plays tasks on each host without waiting to the others. See http://docs.ansible.com/ansible/playbooks_strategies.html.
It looks something like this (taken from the above link):
- hosts: all
strategy: free
tasks:
...
Please note that I didn't check this and I'm very new to Ansible. I was just curious about doing what you described and happened to come acroess this strategy thing.
EDIT:
It seems like this is not exactly what you're trying to do. Maybe "async tasks" is more appropriate as described here: http://docs.ansible.com/ansible/playbooks_async.html.
This includes specifying async
and poll
on a task. The following is taken from the 2nd link I mentioned:
- name: simulate long running op, allow to run for 45 sec, fire and forget
command: /bin/sleep 15
async: 45
poll: 0
I guess you can specify longer async
times if your task is lengthy. You can probably define your three concurrent task this way.
How about Freebase? I think they have an API available, too.
Do not use any reserved keyword as the start of any variable name: eg HOSTNAME will fail as HOST {TYPE|NAME} are reserved
I would go with Ryan's answer if you really want to do this.
In general on a *nix environment, you always want to err on giving away as little permissions as possible.
9 times out of 10, 755 is the ideal permission for this - as the only user with the ability to modify the files will be the webserver. Change this to 775 with your ftp user in a group if you REALLY need to change this.
Since you're new to php by your own admission, here's a helpful link for improving the security of your upload service:

Maybe you can wrap the PowerShell invocation in a .bat
file like so:
rem ps.bat
@echo off
powershell.exe -command "%*"
If you then placed this file under a folder in your PATH
, you could call PowerShell scripts like this:
ps foo 1 2 3
Quoting can get a little messy, though:
ps write-host """hello from cmd!""" -foregroundcolor green
Perhaps using SIMILAR TO
would work ?
SELECT * from table WHERE column SIMILAR TO '(AAA|BBB|CCC)%';
moveBus()
is getting called before initialize()
. Try putting that line at the end of your initialize()
function. Also Lat/Lon 0,0 is off the map (it's coordinates, not pixels), so you can't see it when it moves. Try 54,54. If you want the center of the map to move to the new location, use panTo()
.

What I did is go to Help > Eclipse Marketplace and type "Maven" in the search bar and install the first default Maven client for Eclipse. Everything worked for me from this point.
Hope it helps to you too.
In C, there's not much difference when used in the startup function of the program (which can be main()
, wmain()
, _tmain()
or the default name used by your compiler).
If you return
in main()
, control goes back to the _start()
function in the C library which originally started your program, which then calls exit()
anyways. So it really doesn't matter which one you use.
URI (Uniform Resource Identifier) according to Wikipedia:
a string of characters used to identify a resource.
URL (Uniform Resource Locator) is a URI that implies an interaction mechanism with resource. for example https://www.google.com specifies the use of HTTP as the interaction mechanism. Not all URIs need to convey interaction-specific information.
URN (Uniform Resource Name) is a specific form of URI that has urn as it's scheme. For more information about the general form of a URI refer to https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Syntax
IRI (International Resource Identifier) is a revision to the definition of URI that allows us to use international characters in URIs.
Try this:
var req={StrContactDetails:'data',IsPrimary:'True'}
$.ajax({
type: 'POST',
data: req,
url: '@url.Action("SaveEmergencyContact","Dhp")',
contentType: "application/json; charset=utf-8",
dataType: "json",
data: JSON.stringify(req),
success: function (data) {
alert("Success");
},
error: function (ob, errStr) {
alert("An error occured.Please try after sometime.");
}
});
in these cases you can try ssh if https is stuck.
Also you can try increasing the buffer size to an astronomical figure so that you dont have to worry about the buffer size any more git config http.postBuffer 100000000
<a href="#Foo" onclick="return runMyFunction();">Do it!</a>
and
function runMyFunction() {
//code
return true;
}
This way you will have youf function executed AND you will follow the link AND you will follow the link exactly after your function was successfully run.
To split a string with a delimiter with GNU sed you say:
sed 's/delimiter/\n/g' # GNU sed
For example, to split using :
as a delimiter:
$ sed 's/:/\n/g' <<< "he:llo:you"
he
llo
you
Or with a non-GNU sed:
$ sed $'s/:/\\\n/g' <<< "he:llo:you"
he
llo
you
In this particular case, you missed the g
after the substitution. Hence, it is just done once. See:
$ echo "string1:string2:string3:string4:string5" | sed s/:/\\n/g
string1
string2
string3
string4
string5
g
stands for g
lobal and means that the substitution has to be done globally, that is, for any occurrence. See that the default is 1 and if you put for example 2, it is done 2 times, etc.
All together, in your case you would need to use:
sed 's/:/\\n/g' ~/Desktop/myfile.txt
Note that you can directly use the sed ... file
syntax, instead of unnecessary piping: cat file | sed

Most suggestions will fail if there so much as a single leading or trailing space, which would matter if the file is being edited by hand. This would make it less susceptible in that case:
grep '^[[:blank:]]*ABB\.log[[:blank:]]*$' a.tmp
A simple while-read loop in shell would do this implicitly:
while read file
do
case $file in
(ABB.log) printf "%s\n" "$file"
esac
done < a.tmp
