If you want to access the variables some sort of dynamic you may use reflection. However Reflection works not for local variables. It is only applyable for class attributes.
A rough quick and dirty example is this:
public class T {
public Integer n1;
public Integer n2;
public Integer n3;
public void accessAttributes() throws IllegalArgumentException, SecurityException, IllegalAccessException,
NoSuchFieldException {
for (int i = 1; i < 4; i++) {
T.class.getField("n" + i).set(this, 5);
}
}
}
You need to improve this code in various ways it is only an example. This is also not considered to be good code.
var array =[2,3,1,9,8];
var minvalue = array[0];
for (var i = 0; i < array.length; i++) {
if(array[i]<minvalue)
{
minvalue = array[i];
}
}
console.log(minvalue);
Creating a resource is generally mapped to POST, and that should return the location of the new resource; for example, in a Rails scaffold a CREATE will redirect to the SHOW for the newly created resource. The same approach might make sense for updating (PUT), but that's less of a convention; an update need only indicate success. A delete probably only needs to indicate success as well; if you wanted to redirect, returning the LIST of resources probably makes the most sense.
Success can be indicated by HTTP_OK, yes.
The only hard-and-fast rule in what I've said above is that a CREATE should return the location of the new resource. That seems like a no-brainer to me; it makes perfect sense that the client will need to be able to access the new item.
As @page with pagenumbers don't work in browsers for now I was looking for alternatives.
I've found an answer posted by Oliver Kohll.
I'll repost it here so everyone could find it more easily:
For this answer we are not using @page, which is a pure CSS answer, but work in FireFox 20+ versions. Here is the link of an example.
The CSS is:
#content {
display: table;
}
#pageFooter {
display: table-footer-group;
}
#pageFooter:after {
counter-increment: page;
content: counter(page);
}
And the HTML code is:
<div id="content">
<div id="pageFooter">Page </div>
multi-page content here...
</div>
This way you can customize your page number by editing parametrs to #pageFooter. My example:
#pageFooter:after {
counter-increment: page;
content:"Page " counter(page);
left: 0;
top: 100%;
white-space: nowrap;
z-index: 20;
-moz-border-radius: 5px;
-moz-box-shadow: 0px 0px 4px #222;
background-image: -moz-linear-gradient(top, #eeeeee, #cccccc);
}
This trick worked for me fine. Hope it will help you.

Both lines you posted are fine, but you can do it purely in integers, and it will be the most efficient:
def sum_digits(n):
s = 0
while n:
s += n % 10
n //= 10
return s
or with divmod
:
def sum_digits2(n):
s = 0
while n:
n, remainder = divmod(n, 10)
s += remainder
return s
Even faster is the version without augmented assignments:
def sum_digits3(n):
r = 0
while n:
r, n = r + n % 10, n // 10
return r
> %timeit sum_digits(n)

> %timeit sum_digits2(n)
1000000 loops, best of 3: 716 ns per loop

I had to implement a year diff function which works similarly to sybase datediff. In that case the real year difference is counted, not the rounded day difference. So if there are two dates separated by one day, the year difference can be 1 (see select datediff(year, '20141231', '20150101')
).
If the year diff has to be counted this way then use:
EXTRACT(YEAR FROM date_to) - EXTRACT(YEAR FROM date_from)
Just for the log the (almost) complete datediff function:
CREATE OR REPLACE FUNCTION datediff (datepart IN VARCHAR2, date_from IN DATE, date_to IN DATE)
RETURN NUMBER
AS
diff NUMBER;
BEGIN
diff := CASE datepart
WHEN 'day' THEN TRUNC(date_to,'DD') - TRUNC(date_from, 'DD')
WHEN 'week' THEN (TRUNC(date_to,'DAY') - TRUNC(date_from, 'DAY')) / 7
WHEN 'month' THEN MONTHS_BETWEEN(TRUNC(date_to, 'MONTH'), TRUNC(date_from, 'MONTH'))
WHEN 'year' THEN EXTRACT(YEAR FROM date_to) - EXTRACT(YEAR FROM date_from)
END;
RETURN diff;
END;";
It really doesn't matter.
If you feed .c to a c++ compiler it will compile as cpp, .cc/.cxx is just an alternative to .cpp used by some compilers.
.hpp is an attempt to distinguish header files where there are significant c and c++ differences. A common usage is for the .hpp to have the necessary cpp wrappers or namespace and then include the .h in order to expose a c library to both c and c++.
To get the value:
$query = $this->db->query("YOUR QUERY");
Then, for single row from(in controller):
$query1 = $query->row();
$data['product'] = $query1;
In view, you can use your own code (above code)
I tried Fiddler with its reverse proxy ability which is mentioned by @marxidad and it seems to be working fine, since Fiddler is a familiar UI for me and has the ability to show request/responses in various formats (i.e. Raw, XML, Hex), I accept it as an answer to this question. One thing though. I use WCF and I got the following exception with reverse proxy thing:
The message with To 'http://localhost:8000/path/to/service' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree
I have figured out (thanks Google, erm.. I mean Live Search :p) that this is because my endpoint addresses on server and client differs by port number. If you get the same exception consult to the following MSDN forum message:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2302537&SiteID=1
which recommends to use clientVia Endpoint Behavior explained in following MSDN article:
For everybody who codes Java for Android devices and ends up here: use SparseArray

with this you can use int instead of Integer like;

myMap.put(newPos, newObject);
myMap.get(newPos);

At this point, I received messsage (Windows 7) to allow system access. Then the service reference was updated properly without errors.
You can try this:
-ms-transform: scale(width,height); /* IE 9 */
-webkit-transform: scale(width,height); /* Safari */
transform: scale(width, height);
Example: image "grows" 1.3 times
-ms-transform: scale(1.3,1.3); /* IE 9 */
-webkit-transform: scale(1.3,1.3); /* Safari */
transform: scale(1.3,1.3);
You could create a helper function to take care of that:
/**
* Return string before needle if it exists.
*
* @param string $str
* @param mixed $needle
* @return string
*/
function str_before($str, $needle)
{
$pos = strpos($str, $needle);
return ($pos !== false) ? substr($str, 0, $pos) : $str;
}
Here's a use case:
$sing = 'My name is Luka. I live on the second floor.';
echo str_before($sing, '.'); // My name is Luka

Yes, you will need the mysql c++ connector library. Read on below, where I explain how to get the example given by mysql developers to work.
Note(and solution): IDE: I tried using Visual Studio 2010, but just a few sconds ago got this all to work, it seems like I missed it in the manual, but it suggests to use Visual Studio 2008. I downloaded and installed VS2008 Express for c++, followed the steps in chapter 5 of manual and errors are gone! It works. I'm happy, problem solved. Except for the one on how to get it to work on newer versions of visual studio. You should try the mysql for visual studio addon which maybe will get vs2010 or higher to connect successfully. It can be downloaded from mysql website
Whilst trying to get the example mentioned above to work, I find myself here from difficulties due to changes to the mysql dev website. I apologise for writing this as an answer, since I can't comment yet, and will edit this as I discover what to do and find the solution, so that future developers can be helped.(Since this has gotten so big it wouldn't have fitted as a comment anyways, haha)
@hd1 link to "an example" no longer works. Following the link, one will end up at the page which gives you link to the main manual. The main manual is a good reference, but seems to be quite old and outdated, and difficult for new developers, since we have no experience especially if we missing a certain file, and then what to add.
@hd1's link has moved, and can be found with a quick search by removing the url components, keeping just the article name, here it is anyways: http://dev.mysql.com/doc/connector-cpp/en/connector-cpp-examples-complete-example-1.html
Getting 7.5 MySQL Connector/C++ Complete Example 1 to work
Downloads:
-Get the mysql c++ connector, even though it is bigger choose the installer package, not the zip.
-Get the boost libraries from boost.org, since boost is used in connection.h and mysql_connection.h from the mysql c++ connector
Now proceed:
-Install the connector to your c drive, then go to your mysql server install folder/lib and copy all libmysql files, and paste in your connector install folder/lib/opt
-Extract the boost library to your c drive
Next:
It is alright to copy the code as it is from the example(linked above, and ofcourse into a new c++ project). You will notice errors:
-First: change
cout << "(" << __FUNCTION__ << ") on line " »
<< __LINE__ << endl;
to
cout << "(" << __FUNCTION__ << ") on line " << __LINE__ << endl;
Not sure what that tiny double arrow is for, but I don't think it is part of c++
-Second: Fix other errors of them by reading Chapter 5 of the sql manual, note my paragraph regarding chapter 5 below
[Note 1]: Chapter 5 Building MySQL Connector/C++ Windows Applications with Microsoft Visual Studio If you follow this chapter, using latest c++ connecter, you will likely see that what is in your connector folder and what is shown in the images are quite different. Whether you look in the mysql server installation include and lib folders or in the mysql c++ connector folders' include and lib folders, it will not match perfectly unless they update the manual, or you had a magic download, but for me they don't match with a connector download initiated March 2014.
Just follow that chapter 5,
-But for c/c++, General, Additional Include Directories include the "include" folder from the connector you installed, not server install folder
-While doing the above, also include your boost folder see note 2 below
-And for the Linker, General.. etc use the opt folder from connector/lib/opt
*[Note 2]*A second include needs to happen, you need to include from the boost library variant.hpp, this is done the same as above, add the main folder you extracted from the boost zip download, not boost or lib or the subfolder "variant" found in boostmainfolder/boost.. Just the main folder as the second include
Next:
What is next I think is the Static Build, well it is what I did anyways. Follow it.
Then build/compile. LNK errors show up(Edit: Gone after changing ide to visual studio 2008). I think it is because I should build connector myself(if you do this in visual studio 2010 then link errors should disappear), but been working on trying to get this to work since Thursday, will see if I have the motivation to see this through after a good night sleep(and did and now finished :) ).
With the Multiple SCMs Plugin:
create a different repository entry for each repository you need to checkout (main project or dependancy project.
for each project, in the "advanced" menu (the second "advanced" menu, there are two buttons labeled "advanced" for each repository), find the "Local subdirectory for repo (optional)" textfield. You can specify there the subdirectory in the "workspace" directory where you want to copy the project to. You could map the filesystem of my development computer.
The "second advanced menu" doesn't exist anymore, instead what needs to be done is use the "Add" button (on the "Additional Behaviours" section), and choose "Check out to a sub-directory"
Hope that helps.
This has always worked for me:
SET CurrentDir="%~dp0"
ECHO The current file path this bat file is executing in is the following:
ECHO %CurrentDir%
Pause
Pass by pointer is the only way you could pass "by reference" in C, so you still see it used quite a bit.
The NULL pointer is a handy convention for saying a parameter is unused or not valid, so use a pointer in that case.
References can't be updated once they're set, so use a pointer if you ever need to reassign it.
Prefer a reference in every case where there isn't a good reason not to. Make it const
if you can.
My variation of the solution: (scss)
.modal {
.modal-dialog.modal-fs {
width: 100%;
margin: 0;
box-shadow: none;
height: 100%;
.modal-content {
border: none;
border-radius: 0;
box-shadow: none;
box-shadow: none;
height: 100%;
}
}
}
(css)
.modal .modal-dialog.modal-fs {
width: 100%;
margin: 0;
box-shadow: none;
height: 100%;
}
.modal .modal-dialog.modal-fs .modal-content {
border: none;
border-radius: 0;
box-shadow: none;
box-shadow: none;
height: 100%;
}
Get the file register.py
from this gist. Save it on your C drive or D drive, go to CMD to run it with:
'python register.py'
Then you will be able to install it.
This will work (pure JS, appending to a div of id myDiv
):
Demo: http://jsfiddle.net/4pwvg/
var myParent = document.body;_x000D_
_x000D_
//Create array of options to be added_x000D_
var array = ["Volvo","Saab","Mercades","Audi"];_x000D_
_x000D_
//Create and append select list_x000D_
var selectList = document.createElement("select");_x000D_
selectList.id = "mySelect";_x000D_
myParent.appendChild(selectList);_x000D_
_x000D_
//Create and append the options_x000D_
for (var i = 0; i < array.length; i++) {_x000D_
var option = document.createElement("option");_x000D_
option.value = array[i];_x000D_
option.text = array[i];_x000D_
selectList.appendChild(option);_x000D_
}
_x000D_
Try this...to select the option with text myText
$("#my-Select option[text=" + myText +"]").prop("selected", true);
There is build in forEach loop for array in ECMAScript 5th Edition.
var buttons = document.getElementsByClassName("navButton");
Array.prototype.forEach.call(buttons,function(button) {
button.setAttribute("class", "active");
button.setAttribute("src", "images/arrows/top_o.png");
});
Another possible answer considering also the case that an empty string might contain several whitespace characters for example spaces,tabs,line break characters can be the folllowing pattern.
pattern = r"^(\s*)$"
This pattern matches if the string starts and ends with zero or more whitespace characters.
It was tested in Python 3
public class GlobalClass {
public static int x = 37;
public static String s = "aaa";
}
This way you can access them with GlobalClass.x
and GlobalClass.s
If the device is rooted,
root@mako:/ # settings put global package_verifier_enable 0
Seems to do the trick.
Here's my approach, which simply splits a string by spaces, then for loops the array and increases the count if the array[i] matches a given regex pattern.
function wordCount(str) {
var stringArray = str.split(' ');
var count = 0;
for (var i = 0; i < stringArray.length; i++) {
var word = stringArray[i];
if (/[A-Za-z]/.test(word)) {
count++
}
}
return count
}
Invoked like so:
var str = "testing strings here's a string --.. ? // ... random characters ,,, end of string";
wordCount(str)
(added extra characters & spaces to show accuracy of function)
The str above returns 10, which is correct!
Here is my simple implementation:
class Node:
def __init__(self):
self.data = None
self.next = None
def __str__(self):
return "Data %s: Next -> %s"%(self.data, self.next)
class LinkedList:
def __init__(self):
self.head = Node()
self.curNode = self.head
def insertNode(self, data):
node = Node()
node.data = data
node.next = None
if self.head.data == None:
self.head = node
self.curNode = node
else:
self.curNode.next = node
self.curNode = node
def printList(self):
print self.head
l = LinkedList()
l.insertNode(1)
l.insertNode(2)
l.insertNode(34)
Output:
Data 1: Next -> Data 2: Next -> Data 34: Next -> Data 4: Next -> None
I'm not entirely sure what visual end result you're after, but here's an easy way to blur an image's edge: place a div with the image inside another div with the blurred image.
Working example here: http://jsfiddle.net/ZY5hn/1/
HTML:
<div class="placeholder">
<!-- blurred background image for blurred edge -->
<div class="bg-image-blur"></div>
<!-- same image, no blur -->
<div class="bg-image"></div>
<!-- content -->
<div class="content">Blurred Image Edges</div>
</div>
CSS:
.placeholder {
margin-right: auto;
margin-left:auto;
margin-top: 20px;
width: 200px;
height: 200px;
position: relative;
/* this is the only relevant part for the example */
}
/* both DIVs have the same image */
.bg-image-blur, .bg-image {
background-image: url('http://lorempixel.com/200/200/city/9');
position:absolute;
top:0;
left:0;
width: 100%;
height:100%;
}
/* blur the background, to make blurred edges that overflow the unblurred image that is on top */
.bg-image-blur {
-webkit-filter: blur(20px);
-moz-filter: blur(20px);
-o-filter: blur(20px);
-ms-filter: blur(20px);
filter: blur(20px);
}
/* I added this DIV in case you need to place content inside */
.content {
position: absolute;
top:0;
left:0;
width: 100%;
height: 100%;
color: #fff;
text-shadow: 0 0 3px #000;
text-align: center;
font-size: 30px;
}
Notice the blurred effect is using the image, so it changes with the image color.
I hope this helps.
This code works perfectly from Spark 2.x with Scala 2.11
Import necessary classes
import org.apache.spark.sql.{Row, SparkSession}
import org.apache.spark.sql.types.{DoubleType, StringType, StructField, StructType}
Create SparkSession
Object, and Here it's spark
val spark: SparkSession = SparkSession.builder.master("local").getOrCreate
val sc = spark.sparkContext // Just used to create test RDDs
Let's an RDD
to make it DataFrame
val rdd = sc.parallelize(
Seq(
("first", Array(2.0, 1.0, 2.1, 5.4)),
("test", Array(1.5, 0.5, 0.9, 3.7)),
("choose", Array(8.0, 2.9, 9.1, 2.5))
)
)
Using SparkSession.createDataFrame(RDD obj)
.
val dfWithoutSchema = spark.createDataFrame(rdd)
dfWithoutSchema.show()
+------+--------------------+
| _1| _2|
+------+--------------------+
| first|[2.0, 1.0, 2.1, 5.4]|
| test|[1.5, 0.5, 0.9, 3.7]|
|choose|[8.0, 2.9, 9.1, 2.5]|
+------+--------------------+
Using SparkSession.createDataFrame(RDD obj)
and specifying column names.
val dfWithSchema = spark.createDataFrame(rdd).toDF("id", "vals")
dfWithSchema.show()
+------+--------------------+
| id| vals|
+------+--------------------+
| first|[2.0, 1.0, 2.1, 5.4]|
| test|[1.5, 0.5, 0.9, 3.7]|
|choose|[8.0, 2.9, 9.1, 2.5]|
+------+--------------------+
This way requires the input rdd
should be of type RDD[Row]
.
val rowsRdd: RDD[Row] = sc.parallelize(
Seq(
Row("first", 2.0, 7.0),
Row("second", 3.5, 2.5),
Row("third", 7.0, 5.9)
)
)
create the schema
val schema = new StructType()
.add(StructField("id", StringType, true))
.add(StructField("val1", DoubleType, true))
.add(StructField("val2", DoubleType, true))
Now apply both rowsRdd
and schema
to createDataFrame()
val df = spark.createDataFrame(rowsRdd, schema)
df.show()
+------+----+----+
| id|val1|val2|
+------+----+----+
| first| 2.0| 7.0|
|second| 3.5| 2.5|
| third| 7.0| 5.9|
+------+----+----+
You should have to use DateTime.TryParseExact
.
var newDate = DateTime.ParseExact("20111120",
"yyyyMMdd",
CultureInfo.InvariantCulture);
OR
string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;
if (DateTime.TryParseExact(str,
format,
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None,
out date))
{
//valid
}
"What is it?" and "What does it do?" has been explained above.
I will give a example of "when it should be used".
For example, we have a class with lots of resource like big array in it.
class ResHeavy{ // ResHeavy means heavy resource
public:
ResHeavy(int len=10):_upInt(new int[len]),_len(len){
cout<<"default ctor"<<endl;
}
ResHeavy(const ResHeavy& rhs):_upInt(new int[rhs._len]),_len(rhs._len){
cout<<"copy ctor"<<endl;
}
ResHeavy& operator=(const ResHeavy& rhs){
_upInt.reset(new int[rhs._len]);
_len = rhs._len;
cout<<"operator= ctor"<<endl;
}
ResHeavy(ResHeavy&& rhs){
_upInt = std::move(rhs._upInt);
_len = rhs._len;
rhs._len = 0;
cout<<"move ctor"<<endl;
}
// check array valid
bool is_up_valid(){
return _upInt != nullptr;
}
private:
std::unique_ptr<int[]> _upInt; // heavy array resource
int _len; // length of int array
};
Test code:
void test_std_move2(){
ResHeavy rh; // only one int[]
// operator rh
// after some operator of rh, it becomes no-use
// transform it to other object
ResHeavy rh2 = std::move(rh); // rh becomes invalid
// show rh, rh2 it valid
if(rh.is_up_valid())
cout<<"rh valid"<<endl;
else
cout<<"rh invalid"<<endl;
if(rh2.is_up_valid())
cout<<"rh2 valid"<<endl;
else
cout<<"rh2 invalid"<<endl;
// new ResHeavy object, created by copy ctor
ResHeavy rh3(rh2); // two copy of int[]
if(rh3.is_up_valid())
cout<<"rh3 valid"<<endl;
else
cout<<"rh3 invalid"<<endl;
}
output as below:
default ctor
move ctor
rh invalid
rh2 valid
copy ctor
rh3 valid
We can see that std::move
with move constructor
makes transform resource easily.
Where else is std::move
useful?
std::move
can also be useful when sorting an array of elements. Many sorting algorithms (such as selection sort and bubble sort) work by swapping pairs of elements. Previously, we’ve had to resort to copy-semantics to do the swapping. Now we can use move semantics, which is more efficient.
It can also be useful if we want to move the contents managed by one smart pointer to another.

I know this question is old but I spend an hour trying to export a complex query to csv and I wanted to share my thoughts. First I couldn't get any of the json to csv converters to work (although this one looked promising). What I ended up doing was manually writing the csv file in my mongo script.
This is a simple version but essentially what I did:
print("name,id,email");
db.User.find().forEach(function(user){
print(user.name+","+user._id.valueOf()+","+user.email);
});
This I just piped the query to stdout
mongo test export.js > out.csv
where test
is the name of the database I use.
Name.objects.filter(alias__gt='',alias__isnull=False)

Here's some sample code I used recently to do just that.
It opens a workbook, goes down the rows, if a condition is met it writes some data in the row. Finally it saves the modified file.
from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils
from xlrd import open_workbook # http://pypi.python.org/pypi/xlrd
START_ROW = 297 # 0 based (subtract 1 from excel row number)
col_age_november = 1
col_summer1 = 2
col_fall1 = 3
rb = open_workbook(file_path,formatting_info=True)
r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file
wb = copy(rb) # a writable copy (I can't read values out of this, only write to it)
w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy
for row_index in range(START_ROW, r_sheet.nrows):
age_nov = r_sheet.cell(row_index, col_age_november).value
if age_nov == 3:
#If 3, then Combo I 3-4 year old for both summer1 and fall1
w_sheet.write(row_index, col_summer1, 'Combo I 3-4 year old')
w_sheet.write(row_index, col_fall1, 'Combo I 3-4 year old')
wb.save(file_path + '.out' + os.path.splitext(file_path)[-1])

In the newer versions of Handlebars index (or key in the case of object iteration) is provided by default with the standard each helper.
snippet from : https://github.com/wycats/handlebars.js/issues/250#issuecomment-9514811
The index of the current array item has been available for some time now via @index:
{{#each array}}
{{@index}}: {{this}}
{{/each}}
For object iteration, use @key instead:
{{#each object}}
{{@key}}: {{this}}
{{/each}}
setUpBeforeClass is run before any method execution right after the constructor (run only once)
setUp is run before each method execution
tearDown is run after each method execution
tearDownAfterClass is run after all other method executions, is the last method to be executed. (run only once deconstructor)
Whilst the listed answer is correct, may I suggest that if your column is to hold case sensitive strings you read the documentation and alter your table definition accordingly.
In my case this amounted to defining my column as:
`tag` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT ''
This is in my opinion preferential to adjusting your queries.
you need to specify the min
and target sdk
version in the manifest file.
If not the android.permission.READ_PHONE_STATE
will be added automaticly while exporting your apk file.
<uses-sdk

Nothing from this examples , works for me
for (var i = 0; i < res.results.length; i++) {
$('#list_tags').append('<li class="dd-item" id="'+ res.results[i].id + '"><div class="dd-handle root-group">' + res.results[i].name + '</div></li>');
}
$('.dd-item').click(function () {
console.log($(this).attr('id'));
});
The trim() method removes whitespace from both sides of a string.
You can use a Javascript replace method to remove white space like
"hello world".replace(/\s/g, "");
var out = "hello world".replace(/\s/g, "");_x000D_
console.log(out);

res.erase(it)
always returns the next valid iterator, if you erase the last element it will point to .end()
At the end of the loop ++it
is always called, so you increment .end()
which is not allowed.
Simply checking for .end()
still leaves a bug though, as you always skip an element on every iteration (it
gets 'incremented' by the return from .erase()
, and then again by the loop)
You probably want something like:
while (it != res.end()) {
it = res.erase(it);
}
to erase each element
(for completeness: I assume this is a simplified example, if you simply want every element gone without having to perform an operation on it (e.g. delete) you should simply call res.clear()
)
When you only conditionally erase elements, you probably want something like
for ( ; it != res.end(); ) {
if (condition) {
it = res.erase(it);
} else {
++it;
}
}

I figured out the answer to above problem. Below query will return rows which have even a signle occurrence of characters besides alphabets, numbers, square brackets, curly brackets,s pace and dot. Please note that position of closing bracket ']' in matching pattern is important.
Right ']' has the special meaning of ending a character set definition. It wouldn't make any sense to end the set before you specified any members, so the way to indicate a literal right ']' inside square brackets is to put it immediately after the left '[' that starts the set definition
SELECT * FROM test WHERE REGEXP_LIKE(sampletext, '[^]^A-Z^a-z^0-9^[^.^{^}^ ]' );

To understand the "encoding" attribute, you have to understand the difference between bytes and characters.
Think of bytes as numbers between 0 and 255, whereas characters are things like "a", "1" and "Ä". The set of all characters that are available is called a character set.
Each character has a sequence of one or more bytes that are used to represent it; however, the exact number and value of the bytes depends on the encoding used and there are many different encodings.
Most encodings are based on an old character set and encoding called ASCII which is a single byte per character (actually, only 7 bits) and contains 128 characters including a lot of the common characters used in US English.
For example, here are 6 characters in the ASCII character set that are represented by the values 60 to 65.
Extract of ASCII Table 60-65
+---------------------+
¦ Byte ¦ Character ¦
¦------+--------------¦
¦ 60 ¦ < ¦
¦ 61 ¦ = ¦
¦ 62 ¦ > ¦
¦ 63 ¦ ? ¦
¦ 64 ¦ @ ¦
¦ 65 ¦ A ¦
+---------------------+
In the full ASCII set, the lowest value used is zero and the highest is 127 (both of these are hidden control characters).
However, once you start needing more characters than the basic ASCII provides (for example, letters with accents, currency symbols, graphic symbols, etc.), ASCII is not suitable and you need something more extensive. You need more characters (a different character set) and you need a different encoding as 128 characters is not enough to fit all the characters in. Some encodings offer one byte (256 characters) or up to six bytes.
Over time a lot of encodings have been created. In the Windows world, there is CP1252, or ISO-8859-1, whereas Linux users tend to favour UTF-8. Java uses UTF-16 natively.
One sequence of byte values for a character in one encoding might stand for a completely different character in another encoding, or might even be invalid.
For example, in ISO 8859-1, â is represented by one byte of value 226
, whereas in UTF-8 it is two bytes: 195, 162
. However, in ISO 8859-1, 195, 162
would be two characters, Ã, ¢.
Think of XML as not a sequence of characters but a sequence of bytes.
Imagine the system receiving the XML sees the bytes 195, 162
. How does it know what characters these are?
In order for the system to interpret those bytes as actual characters (and so display them or convert them to another encoding), it needs to know the encoding used in the XML.
Since most common encodings are compatible with ASCII, as far as basic alphabetic characters and symbols go, in these cases, the declaration itself can get away with using only the ASCII characters to say what the encoding is. In other cases, the parser must try and figure out the encoding of the declaration. Since it knows the declaration begins with <?xml
it is a lot easier to do this.
Finally, the version
attribute specifies the XML version, of which there are two at the moment (see Wikipedia XML versions. There are slight differences between the versions, so an XML parser needs to know what it is dealing with. In most cases (for English speakers anyway), version 1.0 is sufficient.

To support unicode:

But I get an error "! [rejected]" and something about "non fast forward"
That's because Git can't merge the changes from the branches into your current master. Let's say you've checked out branch master
, and you want to merge in the remote branch other-branch
. When you do this:
$ git pull origin other-branch
Git is basically doing this:
$ git fetch origin other-branch && git merge other-branch
That is, a pull
is just a fetch
followed by a merge
. However, when pull
-ing, Git will only merge other-branch
if it can perform a fast-forward merge. A fast-forward merge is a merge in which the head of the branch you are trying to merge into is a direct descendent of the head of the branch you want to merge. For example, if you have this history tree, then merging other-branch
would result in a fast-forward merge:
O-O-O-O-O-O
^ ^
master other-branch
However, this would not be a fast-forward merge:
v master
O-O-O
\
\-O-O-O-O
^ other-branch
To solve your problem, first fetch the remote branch:
$ git fetch origin other-branch
Then merge it into your current branch (I'll assume that's master
), and fix any merge conflicts:
$ git merge origin/other-branch
# Fix merge conflicts, if they occur
# Add merge conflict fixes
$ git commit # And commit the merge!
You can simply call filter
multiple times:
query = meta.Session.query(User).filter(User.firstname.like(searchVar1)). \
filter(User.lastname.like(searchVar2))
There is an event Page.Unload
. At that moment page is already rendered in HTML and HTML can't be modified. Still, all page objects are available.
To send an HTTP DELETE with some headers via axios
I've done this:
const deleteUrl = "http//foo.bar.baz";
const httpReqHeaders = {
'Authorization': token,
'Content-Type': 'application/json'
};
// check the structure here: https://github.com/axios/axios#request-config
const axiosConfigObject = {headers: httpReqHeaders};
axios.delete(deleteUrl, axiosConfigObject);
The axios
syntax for different HTTP verbs (GET, POST, PUT, DELETE) is tricky because sometimes the 2nd parameter is supposed to be the HTTP body, some other times (when it might not be needed) you just pass the headers as the 2nd parameter.
However let's say you need to send an HTTP POST request without an HTTP body, then you need to pass undefined
as the 2nd parameter.
Bare in mind that according to the definition of the configuration object (https://github.com/axios/axios#request-config) you can still pass an HTTP body in the HTTP call via the data
field when calling axios.delete
, however for the HTTP DELETE verb it will be ignored.
This confusion between the 2nd parameter being sometimes the HTTP body and some other time the whole config
object for axios
is due to how the HTTP rules have been implemented. Sometimes an HTTP body is not needed for an HTTP call to be considered valid.
You can do:
if not (u0 <= u <= u0+step):
u0 = u0+ step # change the condition until it is satisfied
else:
do sth. # condition is satisfied
Using a loop:
while not (u0 <= u <= u0+step):
u0 = u0+ step # change the condition until it is satisfied
do sth. # condition is satisfied
This is for view controller reusability.
Your view controller shouldn't care if it is being presented as a modal, pushed on a navigation controller, or whatever. If your view controller dismisses itself, then you're assuming it is being presented modally. You won't be able to push that view controller onto a navigation controller.
By implementing a protocol, you let the parent view controller decide how it should be presented/pushed and dismissed/popped.
The correct answer to that is the method lists
, it's very simple like this:
$test=test::select('id')->where('id' ,'>' ,0)->lists('id');

You can convert the datetime to a date then back to a datetime. This will reset the timestamp.
select getdate() --2020-05-05 13:53:35.863 select cast(cast(GETDATE() as date) as datetime) --2020-05-05 00:00:00.000
Try hasattr()
:
if hasattr(a, 'property'):
a.property
EDIT: See zweiterlinde's answer below, who offers good advice about asking forgiveness! A very pythonic approach!
The general practice in python is that, if the property is likely to be there most of the time, simply call it and either let the exception propagate, or trap it with a try/except block. This will likely be faster than hasattr
. If the property is likely to not be there most of the time, or you're not sure, using hasattr
will probably be faster than repeatedly falling into an exception block.
Here you go:
DECLARE
BEGIN
dbms_output.enable(NULL); -- Disables the limit of DBMS
-- Your print here !
END;
All the hidden fields in your fieldset are using the same id, so jquery is only returning the first one. One way to fix this is to create a counter variable and concatenate it to each hidden field id.
This should work for multiplication:

Loop:
beq $5, $0, Exit # if multiplier is 0,terminate loop
andi $3, $5, 1 # mask out the 0th bit in multiplier
beq $3, $0, Shift # if the bit is 0, skip add
addu $2, $2, $4 # add (shifted) multiplicand to product
Shift:
sll $4, $4, 1 # shift up the multiplicand 1 bit
srl $5, $5, 1 # shift down the multiplier 1 bit
j Loop # go for next
Exit: #

To generate the private key:
cd ~
puttygen id_dsa.ppk -O private-openssh -o id_dsa
and to generate the public key:
puttygen id_dsa.ppk -O public-openssh -o id_dsa.pub
Move these keys to ~/.ssh and make sure the permissions are set to private for your private key:
mkdir -p ~/.ssh
mv -i ~/id_dsa* ~/.ssh
chmod 600 ~/.ssh/id_dsa
chmod 666 ~/.ssh/id_dsa.pub
connect with ssh server
ssh -i ~/.ssh/id_dsa username@servername
Port Forwarding to connect mysql remote server
ssh -i ~/.ssh/id_dsa -L 9001:127.0.0.1:3306 username@serverName
One obscure (having just dealt with it), yet possible, cause of this is an internal mod_rewrite rule, in the main config file (not .htaccess) that writes to a path which exists at the root of the server file system. Say you have a /media
directory in your site, and you rewrite something like this:
RewriteRule /some_image.png /media/some_other_location.png
If you have a /media
directory at the root of your server, the rewrite will be attempted to that (resulting in the access denied error) rather than the one in your site directory, since the file system root is checked first by mod_rewrite, for the existence of the first directory in the path, before your site directory.
Do you really need an object? What about:
$myArray[] = array("name" => "my name");
Just use a two-dimensional array.
Output (var_dump):
array(1) {
[0]=>
array(1) {
["name"]=>
string(7) "my name"
}
}
You could access your last entry like this:
echo $myArray[count($myArray) - 1]["name"];
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dp"
android:shape="rectangle">
<solid android:color="@color/colorAccent" />
<corners
android:bottomLeftRadius="500dp"
android:bottomRightRadius="500dp"
android:topLeftRadius="500dp"
android:topRightRadius="500dp" />
</shape>
Now, in which element you want to use this shape just add:
android:background="@drawable/custom_round_ui_shape"
Create a new XML in drawable named "custom_round_ui_shape"
I just had to update legacy Weblogic 8 app to use a data-source instead of hard-coded JDBC string. Datasource JNDI name on the configuration tab in the Weblogic admin showed: "weblogic.jdbc.ESdatasource", below are two ways that worked:
Context ctx = new InitialContext();
DataSource dataSource;
try {
dataSource = (DataSource) ctx.lookup("weblogic.jdbc.ESdatasource");
response.getWriter().println("A " +dataSource);
}catch(Exception e) {
response.getWriter().println("A " + e.getMessage() + e.getCause());
}
//or
try {
dataSource = (DataSource) ctx.lookup("weblogic/jdbc/ESdatasource");
response.getWriter().println("F "+dataSource);
}catch(Exception e) {
response.getWriter().println("F " + e.getMessage() + e.getCause());
}
//use your datasource
conn = datasource.getConnection();
That's all folks. No passwords and initial context factory needed from the inside of Weblogic app.
in your css file add this....
a:hover {
cursor:pointer;
}
if you don't have a css file, add this to the HEAD of your HTML page
<style type="text/css">
a:hover {
cursor:pointer;
}
</style>
also you can use the href="" attribute by returning false at the end of your javascript.
<a href="" onclick="doSomething(); return false;">a link</a>
this is good for many reasons. SEO or if people don't have javascript, the href="" will work. e.g.
<a href="nojavascriptpage.html" onclick="doSomething(); return false;">a link</a>
@see http://www.alistapart.com/articles/behavioralseparation
Edit: Worth noting @BalusC's answer where he mentions :hover
is not necessary for the OP's use case. Although other style can be add with the :hover
selector.
If your input and button are siblings (and they are in your case OP):
<input id="upload"
type="file"
ng-file-select="onFileSelect($files)"
style="display: none;">
<button type="button" uploadfile>Upload</button>
Use a directive to bind the click of your button to the file input like so:
app.directive('uploadfile', function () {
return {
restrict: 'A',
link: function(scope, element) {
element.bind('click', function(e) {
angular.element(e.target).siblings('#upload').trigger('click');
});
}
};
});
If you are utilizing arrays too much then you should include cstring.h
because it has too many functions including finding substrings.
You may use Upsert with $setOnInsert operator.
db.Table.update({noExist: true}, {"$setOnInsert": {xxxYourDocumentxxx}}, {upsert: true})
Or just use $json as an object:
$json->$user = array("first" => $first, "last" => $last);
This is how it is returned without the second parameter (as an instance of stdClass).
One main reason we went with Workstation over Player at my job is because we need to run VMs that use a physical disk as their hard drive instead of a virtual disk. Workstation supports using physical disks while Player does not.
You can clear the error state and empty the stringstream all in one line
std::stringstream().swap(m); // swap m with a default constructed stringstream
This effectively resets m to a default constructed state
dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))
na.omit(dat)
x1 x2
1 1 100
3 3 300
5 5 500
See my answer here: Run only one task and handler from ansible playbook
It is possible to run separate role (from roles/
dir):
ansible -i stage.yml -m include_role -a name=create-os-user localhost
and separate task file:
ansible -i stage.yml -m include_tasks -a file=tasks/create-os-user.yml localhost
If you externalize tasks from role to root tasks/
directory (reuse is achieved by import_tasks: ../../../tasks/create-os-user.yml
) you can run it independently from playbook/role.
Use this tool (uses the new apksigner from Google):
https://github.com/patrickfav/uber-apk-signer
Disclaimer: Im the developer :)
You need to generate a keystore once and use it to sign your unsigned
apk.
Use the keytool
provided by the JDK found in %JAVA_HOME%/bin/
keytool -genkey -v -keystore my.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias app
zipalign
which is a tool provided by the Android SDK found in e.g. %ANDROID_HOME%/sdk/build-tools/24.0.2/
is a mandatory optimization step if you want to upload the apk to the Play Store.
zipalign -p 4 my.apk my-aligned.apk
Note: when using the old jarsigner
you need to zipalign AFTER signing. When using the new apksigner
method you do it BEFORE signing (confusing, I know). Invoking zipalign before apksigner works fine because apksigner preserves APK alignment and compression (unlike jarsigner).
You can verify the alignment with
zipalign -c 4 my-aligned.apk
Use jarsigner
which, like the keytool, comes with the JDK distribution found in %JAVA_HOME%/bin/
and use it like so:
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my.keystore my-app.apk my_alias_name
and can be verified with
jarsigner -verify -verbose my_application.apk
Android 7.0 introduces APK Signature Scheme v2, a new app-signing scheme that offers faster app install times and more protection against unauthorized alterations to APK files (See here and here for more details). Therefore, Google implemented their own apk signer called apksigner
(duh!)
The script file can be found in %ANDROID_HOME%/sdk/build-tools/24.0.3/
(the .jar is in the /lib
subfolder). Use it like this
apksigner sign --ks my.keystore my-app.apk --ks-key-alias alias_name
and can be verified with
apksigner verify my-app.apk
A colleague told me to use scm.branches[0].name
and it worked. I wrapped it to a function in my Jenkinsfile:
def getGitBranchName() {
return scm.branches[0].name
}
You just need to override the method for back button. You can leave the method empty if you want so that nothing will happen when you press back button. Please have a look at the code below:
@Override
public void onBackPressed()
{
// Your Code Here. Leave empty if you want nothing to happen on back press.
}
I use the following command (Suppose your local branch name is "branch-name-local" and remote branch name is "branch-name-remote"):
$ git branch --set-upstream-to=origin/branch-name-remote branch-name-local
If both local and remote branches have the same name, then just do the following:
$ git branch --set-upstream-to=origin/branch-name branch-name

strtok
is an overlooked function for this sort of thing. It is meant to be quite fast.
$s = '233718_This_is_a_string';
$firstPart = strtok( $s, '_' );
$allTheRest = strtok( '' );
Empty string like this will force the rest of the string to be returned.
NB if there was nothing at all after the '_' you would get a FALSE
value for $allTheRest
which, as stated in the documentation, must be tested with ===, to distinguish from other falsy values.
Simply put, "Non-identifying" relationships between Entities is part of ER-Model and is available in Microsoft Visio when designing ER-Diagram. This is required to enforce cardinality between Entities of type " zero or more than zero", or "zero or one". Note this "zero" in cardinality instead of "one" in "one to many".
Now, example of non-identifying relationship where cardinality may be "zero" (non-identifying) is when we say a record / object in one entity-A "may" or "may not" have a value as a reference to the record/s in another Entity-B.
As, there is a possibility for one record of entity-A to identify itself to the records of other Entity-B, therefore there should be a column in Entity-B to have the identity-value of the record of Entity-B. This column may be "Null" if no record in Entity-A identifies the record/s (or, object/s) in Entity-B.
In Object Oriented (real-world) Paradigm, there are situations when an object of Class-B does not necessarily depends (strongly coupled) on object of class-A for its existence, which means Class-B is loosely-coupled with Class-A such that Class-A may "Contain" (Containment) an object of Class-A, as opposed to the concept of object of Class-B must have (Composition) an object of Class-A, for its (object of class-B) creation.
From SQL Query point of view, you can query all records in entity-B which are "not null" for foreign-key reserved for Entity-B. This will bring all records having certain corresponding value for rows in Entity-A alternatively all records with Null value will be the records which do not have any record in Entity-A in Entity-B.

Using Django Extensions, running:
./manage.py reset_db
Will clear the database tables, then running:
./manage.py syncdb
Will recreate them (south may ask you to migrate things).
EF 4.1 to EF 6
There is a strongly typed .Include
which allows the required depth of eager loading to be specified by providing Select expressions to the appropriate depth:
using System.Data.Entity; // NB!
var company = context.Companies
.Include(co => co.Employees.Select(emp => emp.Employee_Car))
.Include(co => co.Employees.Select(emp => emp.Employee_Country))
.FirstOrDefault(co => co.companyID == companyID);
The Sql generated is by no means intuitive, but seems performant enough. I've put a small example on GitHub here
EF Core
EF Core has a new extension method, .ThenInclude()
, although the syntax is slightly different:
var company = context.Companies
.Include(co => co.Employees)
.ThenInclude(emp => emp.Employee_Car)
.Include(co => co.Employees)
.ThenInclude(emp => emp.Employee_Country)
With some notes
Employees.Employee_Car
and Employees.Employee_Country
), if you need to include 2 or more child properties of an intermediate child collection, you'll need to repeat the .Include
navigation for the collection for each child of the collection..ThenInclude
to preserve your sanity.Edited and fixed (thanks to Shredder)
If you mean you want to open a new tab, try the below:
protected void Page_Load(object sender, EventArgs e)
{
this.Form.Target = "_blank";
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("Otherpage.aspx");
}
This will keep the original page to stay open and cause the redirects on the current page to affect the new tab only.

I think this would be a better way to do it in Swift:
func filterContentForSearchText(searchText:NSString, scope:NSString)
{
searchResults = recipes.filter { name.rangeOfString(searchText) != nil }
}
this is variation of Dennis method, looks more elegant in the scripts.
function definition:
define(){ IFS='\n' read -r -d '' ${1} || true; }
usage:
define VAR <<'EOF'
abc'asdf"
$(dont-execute-this)
foo"bar"''
EOF
echo "$VAR"
enjoy
p.s. made a 'read loop' version for shells that do not support read -d
. should work with set -eu
and unpaired backticks, but not tested very well:
define(){ o=; while IFS="\n" read -r a; do o="$o$a"'
'; done; eval "$1=\$o"; }
Here's one way in XSLT 2
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"','''')"/> </xsl:template> </xsl:stylesheet>
Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:variable name="apos">'</xsl:variable> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"',$apos)"/> </xsl:template> </xsl:stylesheet>
If you take a look at the source code of Spring Data JPA, and particularly the PartTreeJpaQuery
class, you will see that is tries to instantiate PartTree
.
Inside that class the following regular expression
private static final Pattern PREFIX_TEMPLATE = Pattern.compile("^(find|read|get|count|query)(\\p{Lu}.*?)??By")
should indicate what is allowed and what's not.
Of course if you try to add such a method you will actually see that is does not work and you get the full stacktrace.
I should note that I was using looking at version 1.5.0.RELEASE
of Spring Data JPA
Given that a list can hold any type of object, there is no built in method which allows you to sum all the elements. You could do something like this:
int sum = 0;
for( Integer i : ( ArrayList<Integer> )tt ) {
sum += i;
}
Alternatively you could create your own container type which inherits from ArrayList but also implements a method called sum() which implements the code above.
Here is a stripped down example, using as little HTML markup as possible.
The overlay is provided by the :before
pseudo element on the .content
container.
No z-index is required, :before
is naturally layered over the video element.
The .content
container is position: relative
so that the position: absolute
overlay is positioned in relation to it.
The overlay is stretched to cover the entire .content
div width with left / right / bottom
and left
set to 0
.
The width of the video is controlled by the width of its container with width: 100%
.content {
position: relative;
width: 500px;
margin: 0 auto;
padding: 20px;
}
.content video {
width: 100%;
display: block;
}
.content:before {
content: '';
position: absolute;
background: rgba(0, 0, 0, 0.5);
border-radius: 5px;
top: 0;
right: 0;
bottom: 0;
left: 0;

A decent alternative if you're using firefox is the XRefresh plugin. It will reload your page everytime it detect the file has been modified. So rather than just refreshing every 5 seconds, it will just refresh when you hit save in your HTML editor.
You can do this for achieving only one return statement - declare it at start and output it at the end - problem solved:
$content = "";
$return = false;
if($content != "")
{
$return = true;
}
else
{
$return = false;
}
return $return;

This is a very simple step. Checkout file to the commit id we want, here one commit id before, and then just git commit amend and we are done.
# git checkout <previous commit_id> <file_name>
# git commit --amend
This is very handy. If we want to bring any file to any prior commit id at the top of commit, we can easily do.
You have your ssh clone
statement wrong: git clone username [email protected]:root/test.git
That statement would try to clone a repository named username
into the location relative to your current path, [email protected]:root/test.git
.
You want to leave out username
:
git clone [email protected]:root/test.git
Yes, you can find out element by data attribute.

For this, you need to use the date, but ignore the time value.
Ordinarily a date would be a DateTime with time of 00:00:00
The DateTime
type has a .Date
property which returns the DateTime
with the time value set as above.

Just did the test and it works with toEqual
please find my test:
describe('toEqual', function() {
it('passes if arrays are equal', function() {
var arr = [1, 2, 3];
expect(arr).toEqual([1, 2, 3]);
});
});
Just for information:
toBe() versus toEqual(): toEqual() checks equivalence. toBe(), on the other hand, makes sure that they're the exact same object.
The correct way to do this is to use show
and hide
:
$('#id').hide();
$('#id').show();
An alternate way is to use the jQuery css method:
$("#id").css("display", "none");
$("#id").css("display", "block");

error: failed to push some refs to 'http://REPO.git'
This is caused by the repository still being empty. There are no commits in the repository and thus no master branch to push to the server.
It worked for me
Resolution
1) git init
2)git commit -m "first commit"
3)git add app
4)git commit -m "first commit"
5)git push -u origin master
Now that PowerShell Core (aka v6) has been released, and people may want to write cross-platform scripts, many of the answers here will not work on anything other than Windows.
[Environment]::UserName
appears to be the best way of getting the current username on all platforms supported by PowerShell Core if you don't want to add platform detection and special casing to your code.
If you're just trying to find out where npm is installing your global module (the title of this thread), look at the output when running npm install -g sample_module
$ npm install -g sample_module C:\Users\user\AppData\Roaming\npm\sample_module -> C:\Users\user\AppData\Roaming\npm\node_modules\sample_module\bin\sample_module.js + [email protected] updated 1 package in 2.821s
For Merge sort worst case is O(n*log(n))
, for Quick sort: O(n
2)
. For other cases (avg, best) both have O(n*log(n))
. However Quick sort is space constant where Merge sort depends on the structure you're sorting.
See this comparison.
You can also see it visually.
you need os.path.realpath
(sample below adds the parent directory to your path)
import sys,os
sys.path.append(os.path.realpath('..'))
According to the latest documentation about PyMongo titled Insert a Document (insert is deprecated) and following defensive approach, you should insert and update as follows:
result = mycollection.insert_one(post)
post = mycollection.find_one({'_id': result.inserted_id})
if post is not None:
post['newfield'] = "abc"
mycollection.save(post)
You can make a class which extends org.xml.sax.helpers.DefaultHandler and call
start_<tag_name>(Attributes attrs);
and
end_<tag_name>();
For it is:
start_request_queue(attrs);
etc.
And then extends that class and implement xml configuration file parsers you want. Example:
... public void startElement(String uri, String name, String qname, org.xml.sax.Attributes attrs) throws org.xml.sax.SAXException { Class[] args = new Class[2]; args[0] = uri.getClass(); args[1] = org.xml.sax.Attributes.class; try { String mname = name.replace("-", ""); java.lang.reflect.Method m = getClass().getDeclaredMethod("start" + mname, args); m.invoke(this, new Object[] { uri, (org.xml.sax.Attributes)attrs }); }
catch (IllegalAccessException e) { throw new RuntimeException(e); }
catch (NoSuchMethodException e) { throw new RuntimeException(e); }
catch (java.lang.reflect.InvocationTargetException e) { org.xml.sax.SAXException se = new org.xml.sax.SAXException(e.getTargetException()); se.setStackTrace(e.getTargetException().getStackTrace()); }
and in a particular configuration parser:
public void start_Request(String uri, org.xml.sax.Attributes attrs) { // make sure to read attributes correctly System.err.println("Request, name="+ attrs.getValue(0); }
What programming languages can one use to develop iPhone, iPod Touch and iPad (iOs) applications?
Ruby, Python, Lua, Scheme, Lisp, Smalltalk, C#, Haskell, ActionScript, JavaScript, Objective-C, C++, C. That's just the ones that pop into my head right now. I'm sure there's hundreds if not thousands of others. (E.g. there's no reason why you couldn't use any .NET language with MonoTouch, i.e. VB.NET, F#, Nemerle, Boo, Cobra, ...)
Also are there plans in the future to expand the amount of programming languages that iOs will support?
Sure. Pretty much every programming language community on this planet is currently working on getting their language to run on iOS.
Also, a lot of people are working on programming languages specifically designed for touch devices such as iPod touch, iPhone and iPad, e.g. Phil Mercurio's Thyrd language.
There are two ways to delete a stash:
$ git stash drop <stash_id>
. $ git stash clear
.Use both of them with caution, it maybe is difficult to revert the once deleted stashes.
Here is the reference article.
You need to create the project on GitHub first. After that go to the project directory and run in terminal:
git init
git remote add origin https://github.com/xxx/yyy.git
git add .
git commit -m "first commit"
git push -u origin master
UPDATE table1
SET
`ID` = (SELECT table2.id FROM table2 WHERE table1.`name`=table2.`name`)
You can also use PowerShell to quickly replace words or character reptitions. PowerShell is for Windows. Current version is 3.0.
$oldfile = "$env:windir\WindowsUpdate.log"
$newfile = "$env:temp\newfile.txt"
$text = (Get-Content -Path $oldfile -ReadCount 0) -join "`n"
$text -replace '/(.)\1{9,}/', ' ' | Set-Content -Path $newfile

Create a ViewController with the UITableViewDelegate and UITableViewDataSource protocols. Then create a tableView inside it, declaring its style to be UITableViewStyle.grouped. This will fix the headers.
lazy var tableView: UITableView = {
let view = UITableView(frame: UIScreen.main.bounds, style: UITableViewStyle.grouped)
view.delegate = self
view.dataSource = self
view.separatorStyle = .none
return view
}()
If you're using Angularjs, you can use the angular-materialize plugin, which provides some handy directives. Then you don't need to initialize in the js, just add material-select
to your select:
<div input-field>
<select class="" ng-model="select.value1" material-select>
<option ng-repeat="value in select.choices">{{value}}</option>
</select>
</div>
I tried re-creating this, and .someclass.notip
was being generated for me but .someclass:not(.notip)
was not, for as long as I did not have the @mixin tip()
defined. Once I had that, it all worked.
http://sassmeister.com/gist/9775949
$dropdown-width: 100px;
$comp-tip: true;
@mixin tip($pos:right) {
}
@mixin dropdown-pos($pos:right) {
&:not(.notip) {
@if $comp-tip == true{
@if $pos == right {
top:$dropdown-width * -0.6;
background-color: #f00;
@include tip($pos:$pos);
}
}
}
&.notip {
@if $pos == right {
top: 0;
left:$dropdown-width * 0.8;
background-color: #00f;
}
}
}
.someclass { @include dropdown-pos(); }
EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'.
it what I get when I remove @mixin tip($pos:right) { }
Add
<form target="_blank" ...></form>
or
form.setAttribute("target", "_blank");
to your form's definition.
I think this is what you are looking for? If you are looking to add a blur effect to a div element, you can do this directly through CSS Filters-- See fiddle: http://jsfiddle.net/ayhj9vb0/
div {
-webkit-filter: blur(5px);
-moz-filter: blur(5px);
-o-filter: blur(5px);
-ms-filter: blur(5px);
filter: blur(5px);
width: 100px;
height: 100px;
background-color: #ccc;
}
Set a zero height table footer view (perhaps in your viewDidLoad
method), like so:
Swift:
tableView.tableFooterView = UIView()
Objective-C:
tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
Because the table thinks there is a footer to show, it doesn't display any cells beyond those you explicitly asked for.
Interface builder pro-tip:
If you are using a xib/Storyboard, you can just drag a UIView (with height 0pt) onto the bottom of the UITableView.
So, @Vivek has got the solution to the problem through a dialogue in the Comments rather than through an actual answer.

Who says SO is a Q&A site not a forum? Er, me, amongst others. Anyway, in the absence of an accepted answer to this question I proffer a link to an answer of mine on the topic of UTL_FILE.FOPEN()
. Find it here.
P.S. I'm marking this answer Community Wiki, because it's not a proper answer to this question, just a redirect to somewhere else.
I wrote an App that runs a WebServer (REST-Like) on your Android Phone, so you can set the GPS position remotely. The website provides an Map on which you can click to set a new position, or use the "wasd" keys to move in any direction. The app was a quick solution so there is nearly no UI nor Documentation, but the implementation is straight forward and you can look everything up in the (only four) classes.
Project repository: https://github.com/juliusmh/RemoteGeoFix
Try running all targets individually to check that all are running correct
run ant target name to run a target individually
e.g. ant build-project
Also the default target you specified is
project basedir="." default="build" name="iControlSilk4J"
This will only execute build-subprojects,build-project and init
it work in my case, oldSensor and newSnsor - oldView and newView:
private void replaceSensors(View oldSensor, View newSensor) {
ViewGroup parent = (ViewGroup) oldSensor.getParent();
if (parent == null) {
return;
}
int indexOldSensor = parent.indexOfChild(oldSensor);
int indexNewSensor = parent.indexOfChild(newSensor);
parent.removeView(oldSensor);
parent.addView(oldSensor, indexNewSensor);
parent.removeView(newSensor);
parent.addView(newSensor, indexOldSensor);
}
sys .argv will display the command line args passed when running a script or you can say sys.argv will store the command line arguments passed in python while running from terminal.
Just try this:
import sys
print sys.argv
argv stores all the arguments passed in a python list. The above will print all arguments passed will running the script.
Now try this running your filename.py like this:
python filename.py example example1
this will print 3 arguments in a list.
sys.argv[0] #is the first argument passed, which is basically the filename.
Similarly, argv1 is the first argument passed, in this case 'example'
A similar question has been asked already here btw. Hope this helps!
You can use jstat, like :

An improvement to the solution of bumerang to import data to PuTTY portable
.
Simply moving exported putty.reg
(with m0nhawk solution) to PuTTYPortable\Data\settings\
didn't work. PuTTY Portable backup the file and create a new empty one.
To workaround this issue, merge both putty.reg
copying manually the config you want to migrate from your exported putty.reg
to the newly created PuTTYPortable\Data\settings\putty.reg
below following lines.
REGEDIT4
[HKEY_CURRENT_USER\Software\SimonTatham\PuTTY]
"RandSeedFile"="D:\\Programme\\PuTTYPortable\\Data\\settings\\PUTTY.RND"
The problem could be on this line:
var selectedText2 = $("#SelectedCountryId:selected").text();
It's looking for the item with id of SelectedCountryId
that is selected, where you really want the option that's selected under SelectedCountryId
, so try:
$('#SelectedCountryId option:selected').text()
I have created a javascript function that looks if he has enough space on the right side. If it has he will show it on the right side, else he will display it on the left side
Tested in:
Javascript:
$(document).ready(function(){
//little fix for the poisition.
var newPos = $(".fixed-menuprofile .dropdown-submenu").offset().left - $(this).width();
$(".fixed-menuprofile .dropdown-submenu").find('ul').offset({ "left": newPos });
$(".fixed-menu .dropdown-submenu").mouseover(function() {
var submenuPos = $(this).offset().left + 325;
var windowPos = $(window).width();
var oldPos = $(this).offset().left + $(this).width();
var newPos = $(this).offset().left - $(this).width();
if( submenuPos > windowPos ){
$(this).find('ul').offset({ "left": newPos });
} else {
$(this).find('ul').offset({ "left": oldPos });
}
});
});
because I don't want to add this fix on every menu items I created a new class on it. place the fixed-menu on the ul:
<ul class="dropdown-menu fixed-menu">
I hope this works out for you.
ps. little bug in safari and chrome, first hover will place it to mutch to the left will update this post if I fixed it.
I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)
public static bool IsStringType(object data)
{
return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
}
using this func
private static String strDuration(long duration) {
int ms, s, m, h, d;
double dec;
double time = duration * 1.0;
time = (time / 1000.0);
dec = time % 1;
time = time - dec;
ms = (int)(dec * 1000);
time = (time / 60.0);
dec = time % 1;
time = time - dec;
s = (int)(dec * 60);
time = (time / 60.0);
dec = time % 1;
time = time - dec;
m = (int)(dec * 60);
time = (time / 24.0);
dec = time % 1;
time = time - dec;
h = (int)(dec * 24);
d = (int)time;
return (String.format("%d d - %02d:%02d:%02d.%03d", d, h, m, s, ms));
}
when you need to call derived class destructor from base class. you need to declare virtual base class destructor in base class.
As far as I understood the problem, we can find palindromes around a center index and span our search both ways, to the right and left of the center. Given that and knowing there's no palindrome on the corners of the input, we can set the boundaries to 1 and length-1. While paying attention to the minimum and maximum boundaries of the String, we verify if the characters at the positions of the symmetrical indexes (right and left) are the same for each central position till we reach our max upper bound center.
The outer loop is O(n) (max n-2 iterations), and the inner while loop is O(n) (max around (n / 2) - 1 iterations)
Here's my Java implementation using the example provided by other users.
class LongestPalindrome {
/**
* @param input is a String input
* @return The longest palindrome found in the given input.
*/
public static String getLongestPalindrome(final String input) {
int rightIndex = 0, leftIndex = 0;
String currentPalindrome = "", longestPalindrome = "";
for (int centerIndex = 1; centerIndex < input.length() - 1; centerIndex++) {
leftIndex = centerIndex - 1; rightIndex = centerIndex + 1;
while (leftIndex >= 0 && rightIndex < input.length()) {
if (input.charAt(leftIndex) != input.charAt(rightIndex)) {
break;
}
currentPalindrome = input.substring(leftIndex, rightIndex + 1);
longestPalindrome = currentPalindrome.length() > longestPalindrome.length() ? currentPalindrome : longestPalindrome;
leftIndex--; rightIndex++;
}
}
return longestPalindrome;
}
public static void main(String ... args) {
String str = "HYTBCABADEFGHABCDEDCBAGHTFYW12345678987654321ZWETYGDE";
String longestPali = getLongestPalindrome(str);
System.out.println("String: " + str);
System.out.println("Longest Palindrome: " + longestPali);
}
}
The output of this is the following:
marcello:datastructures marcello$ javac LongestPalindrome
marcello:datastructures marcello$ java LongestPalindrome
String: HYTBCABADEFGHABCDEDCBAGHTFYW12345678987654321ZWETYGDE
Longest Palindrome: 12345678987654321
I never liked the way of asserting exceptions with Junit. If I use the "expected" in the annotation, seems from my point of view we're violating the "given, when, then" pattern because the "then" is placed at the top of the test definition.
Also, if we use "@Rule", we have to deal with so much boilerplate code. So, if you can install new libraries for your tests, I'd suggest to have a look to the AssertJ (that library now comes with SpringBoot)
Then a test which is not violating the "given/when/then" principles, and it is done using AssertJ to verify:
1 - The exception is what we're expecting. 2 - It has also an expected message
Will look like this:
@Test
void should_throwIllegalUse_when_idNotGiven() {
//when
final Throwable raisedException = catchThrowable(() -> getUserDAO.byId(null));
//then
assertThat(raisedException).isInstanceOf(IllegalArgumentException.class)
.hasMessageContaining("Id to fetch is mandatory");
}
I've been trying to run an Android Google Maps v2 under an emulator, and I found many ways to do that, but none of them worked for me. I have always this warning in the Logcat Google Play services out of date. Requires 3025100 but found 2010110
and when I want to update Google Play services on the emulator nothing happened. The problem was that the com.google.android.gms APK was not compatible with the version of the library in my Android SDK.
I installed these files "com.google.android.gms.apk", "com.android.vending.apk" on my emulator and my app Google Maps v2 worked fine. None of the other steps regarding /system/app were required.
"But i want to know a better way to do this, if there is one ?"
Yes, since you seem to already have the original object, there's no reason to fetch it again from the Array.
function Update(keyValue, newKey, newValue)
{
keyValue.Key = newKey;
keyValue.Value = newValue;
}
As others have mentioned, and counter to what the method name would imply, writelines
does not add line separators. This is a textbook case for a generator. Here is a contrived example:
def item_generator(things):
for item in things:
yield item
yield '\n'
def write_things_to_file(things):
with open('path_to_file.txt', 'wb') as f:
f.writelines(item_generator(things))
Benefits: adds newlines explicitly without modifying the input or output values or doing any messy string concatenation. And, critically, does not create any new data structures in memory. IO (writing to a file) is when that kind of thing tends to actually matter. Hope this helps someone!
According to this snippet here, this approach should be good for long strings:
private string StringToHex(string hexstring)
{
StringBuilder sb = new StringBuilder();
foreach (char t in hexstring)
{
//Note: X for upper, x for lower case letters
sb.Append(Convert.ToInt32(t).ToString("x"));
}
return sb.ToString();
}
usage:
string result = StringToHex("Hello world"); //returns "48656c6c6f20776f726c64"
Another approach in one line
string input = "Hello world";
string result = String.Concat(input.Select(x => ((int)x).ToString("x")));
Worked perfectly for me to calculate SQL database size in SQL Server 2012
exec sp_spaceused
Try this:
System.Configuration.ConfigurationFileMap fileMap = new ConfigurationFileMap(strConfigPath); //Path to your config file
System.Configuration.Configuration configuration = System.Configuration.ConfigurationManager.OpenMappedMachineConfiguration(fileMap);
5 years too late, I know, but no-one actually answered the question:
Then, why should I use the bare repository and why not? What's the practical difference? That would not be beneficial to more people working on a project, I suppose.
What are your methods for this kind of work? Suggestions?
To quote directly from the Loeliger/MCullough book (978-1-449-31638-9, p196/7):
A bare repository might seem to be of little use, but its role is crucial: to serve as an authoritative focal point for collaborative development. Other developers
clone
andfetch
from the bare repository andpush
updates to it... if you set up a repository into which developerspush
changes, it should be bare. In effect, this is a special case of the more general best practice that a published repository should be bare.
The below code will give you list of all the rows:-
df[df['C'] != 'XYZ']
To store the values from the above code into a dataframe :-
newdf = df[df['C'] != 'XYZ']

Solution:
You must explicitly add the parameter -CAfile your-ca-file.pem
.
Note: I tried also param -CApath
mentioned in another answers, but is does not works for me.
Explanation:
Error unable to get local issuer certificate
means, that the openssl
does not know your root CA cert.
Note: If you have web server with more domains, do not forget to add also -servername your.domain.net
parameter. This parameter will "Set TLS extension servername in ClientHello". Without this parameter, the response will always contain the default SSL cert (not certificate, that match to your domain).
Technically, as long as the interpreted code ISN'T downloaded (excluding JavaScript), the app may be approved. Rhomobiles "Rhodes" framework does just that, bundling mobile Ruby, a lightweight version of Rails, and your app for distribution via the app-store. Because both the interpreter and the interpreted code are packaged into the final application - Apple doesn't find it objectionable.
http://rhomobile.com/products/rhodes/
Even after the latest apple press release - rhodes apps (mobile ruby) are still viable on the app-store. I'd find it hard to believe that tinyPy or pyObjC wouldn't find a place if there is a willing developer community.
You can center a fixed
or absolute
positioned element setting right
and left
to 0
, and then margin-left
& margin-right
to auto
as if you were centering a static
positioned element.
#example {
position: fixed;
/* center the element */
right: 0;
left: 0;
margin-right: auto;
margin-left: auto;
/* give it dimensions */
min-height: 10em;
width: 90%;
}
Try this:
<marquee behavior="" Height="200px" direction="up" scroll onmouseover="this.setAttribute('scrollamount', 0, 0);this.stop();" onmouseout="this.setAttribute('scrollamount', 3, 0);this.start();" scrollamount="3" valign="center">

</marquee>
You can increase the Heap Size by passing JVM parameters -Xms and -Xmx like below:
For Jar Files:
java -jar -Xms4096M -Xmx6144M jarFilePath.jar
For Java Files:
java -Xms4096M -Xmx6144M ClassName
The above parameters increase the InitialHeapSize (-Xms) to 4GB (4096 MB) and MaxHeapSize(-Xmx) to 6GB (6144 MB).
But, the Young Generation Heap Size will remain same and the additional HeapSize will be added to the Old Generation Heap Size. To equalize the size of Young Gen Heap and Old Gen Heap, use -XX:NewRatio=1 -XX:-UseAdaptiveSizePolicy params.
java -jar -Xms4096M -Xmx6144M -XX:NewRatio=1 -XX:-UseAdaptiveSizePolicy pathToJarFile.jar
-XX:NewRatio = Old Gen Heap Size : Young Gen HeapSize (You can play with this ratio to get your desired ratio).
You have a few different options:
The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts
You could try this:
$in_str = 'this is a test';
$hex_ary = array();
foreach (str_split($in_str) as $chr) {
$hex_ary[] = sprintf("%02X", ord($chr));
}
echo implode(' ',$hex_ary);
any('abc' in item for item in mylist)
Character.isDigit(string.charAt(0))
Note that this will allow any Unicode digit, not just 0-9. You might prefer:
char c = string.charAt(0);
isDigit = (c >= '0' && c <= '9');
Or the slower regex solutions:
s.substring(0, 1).matches("\\d")
// or the equivalent
s.substring(0, 1).matches("[0-9]")
However, with any of these methods, you must first be sure that the string isn't empty. If it is, charAt(0)
and substring(0, 1)
will throw a StringIndexOutOfBoundsException
. startsWith
does not have this problem.
To make the entire condition one line and avoid length checks, you can alter the regexes to the following:
s.matches("\\d.*")
// or the equivalent
s.matches("[0-9].*")
If the condition does not appear in a tight loop in your program, the small performance hit for using regular expressions is not likely to be noticeable.
We can control tab size by file type with EditorConfig and its EditorConfig for VS Code extension. We then can make Alt + Shift + F specific to each file type.
Open the VS Code command palette with CTRL + P and paste this:
ext install EditorConfig
[*]
indent_style = space
[*.{js,ts,json}]
indent_size = 2
[*.java]
indent_size = 4
[*.go]
indent_style = tab
EditorConfig overrides whatever settings.json configures for the editor. There is no need to change editor.detectIndentation
.
This this, it worked for me:
Style:
.pagination {
display: flex;
justify-content: center;
}
.pagination li {
display: block;
}
And blade:
<div class="pagination">
{{ $myCollection->render() }}
</div>
I had the same problem with timestamp eg:'29-JUL-20 04.46.42.000000000 PM'. I wanted to turn it into 'yyyy-MM-dd' format. The solution that finally works for me is
SELECT TO_CHAR(mytimestamp, 'YYYY-MM-DD') FROM mytable;
OK so I created a static async method. That disabled the control that launches the action and changes the application cursor. It runs the action as a task and waits for to finish. Control returns to the caller while it waits. So the application remains responsive, even while the busy icon spins.
async public static void LengthyOperation(Control control, Action action)
{
try
{
control.Enabled = false;
Application.UseWaitCursor = true;
Task doWork = new Task(() => action(), TaskCreationOptions.LongRunning);
Log.Info("Task Start");
doWork.Start();
Log.Info("Before Await");
await doWork;
Log.Info("After await");
}
finally
{
Log.Info("Finally");
Application.UseWaitCursor = false;
control.Enabled = true;
}
Here's the code form the main form
private void btnSleep_Click(object sender, EventArgs e)
{
var control = sender as Control;
if (control != null)
{
Log.Info("Launching lengthy operation...");
CursorWait.LengthyOperation(control, () => DummyAction());
Log.Info("...Lengthy operation launched.");
}
}
private void DummyAction()
{
try
{
var _log = NLog.LogManager.GetLogger("TmpLogger");
_log.Info("Action - Sleep");
TimeSpan sleep = new TimeSpan(0, 0, 16);
Thread.Sleep(sleep);
_log.Info("Action - Wakeup");
}
finally
{
}
}
I had to use a separate logger for the dummy action (I am using Nlog) and my main logger is writing to the UI (a rich text box). I wasn't able to get the busy cursor show only when over a particular container on the form (but I didn't try very hard.) All controls have a UseWaitCursor property, but it doesn't seem have any effect on the controls I tried (maybe because they weren't on top?)
Here's the main log, which shows things happening in the order we expect:
16:51:33.1064 Launching lengthy operation...
16:51:33.1215 Task Start
16:51:33.1215 Before Await
16:51:33.1215 ...Lengthy operation launched.
16:51:49.1276 After await
16:51:49.1537 Finally
It is rare, in reality, that you would want to use an array. Definitely use a List<T>
any time you want to add/remove data, since resizing arrays is expensive. If you know the data is fixed length, and you want to micro-optimise for some very specific reason (after benchmarking), then an array may be useful.
List<T>
offers a lot more functionality than an array (although LINQ evens it up a bit), and is almost always the right choice. Except for params
arguments, of course. ;-p
As a counter - List<T>
is one-dimensional; where-as you have have rectangular (etc) arrays like int[,]
or string[,,]
- but there are other ways of modelling such data (if you need) in an object model.
See also:
That said, I make a lot of use of arrays in my protobuf-net project; entirely for performance:
byte[]
is pretty much essential for encoding;byte[]
buffer which I fill before sending down to the underlying stream (and v.v.); quicker than BufferedStream
etc;Foo[]
rather than List<Foo>
), since the size is fixed once built, and needs to be very fast.But this is definitely an exception; for general line-of-business processing, a List<T>
wins every time.
You can use java.nio which is faster than classical Input/Output stream:
http://java.sun.com/javase/6/docs/technotes/guides/io/index.html
You can chain .fail()
callback for error response.
$.get('http://example.com/page/2/', function(data){
$(data).find('#reviews .card').appendTo('#reviews');
})
.fail(function() {
//Error logic
})
A point in favor of alias
instead of alias_method
is that its semantic is recognized by rdoc, leading to neat cross references in the generated documentation, while rdoc completely ignore alias_method
.
This is a pretty way to do that:
function time_converter($sec_time, $format='h:m:s'){
$hour = intval($sec_time / 3600) >= 10 ? intval($sec_time / 3600) : '0'.intval($sec_time / 3600);
$minute = intval(($sec_time % 3600) / 60) >= 10 ? intval(($sec_time % 3600) / 60) : '0'.intval(($sec_time % 3600) / 60);
$sec = intval(($sec_time % 3600) % 60) >= 10 ? intval(($sec_time % 3600) % 60) : '0'.intval(($sec_time % 3600) % 60);
$format = str_replace('h', $hour, $format);
$format = str_replace('m', $minute, $format);
$format = str_replace('s', $sec, $format);
return $format;
}
try this:
head -1 /etc/*release | awk '{print $1}'
If you're using zsh, you can use multiple redirections, so you don't even need tee
:
./cmd 1>&1 2>&2 1>out_file 2>err_file
Here you're simply redirecting each stream to itself and the target file.
Full example
% (echo "out"; echo "err">/dev/stderr) 1>&1 2>&2 1>/tmp/out_file 2>/tmp/err_file
out
err
% cat /tmp/out_file
out
% cat /tmp/err_file
err
Note that this requires the MULTIOS
option to be set (which is the default).
MULTIOS
Perform implicit
tee
s orcat
s when multiple redirections are attempted (see Redirection).
Doing the expicit casting to the "int" solves the problem in my case. I had the same issue. So:
int count = (int)[myColors count];
Creating and using the key is the way to go. The usage is free until your application reaches 25.000 calls per day on 90 consecutive days.
BTW.: In the google Developer documentation it says you shall add the api key as option {key:yourKey} when calling the API to create new instances. This however doesn't shush the console warning. You have to add the key as a parameter when including the api.
<script src="https://maps.googleapis.com/maps/api/js?key=yourKEYhere"></script>
Get the key here: GoogleApiKey Generation site
It is defined as:
typedef unsigned long DWORD;
However, according to the MSDN:
On 32-bit platforms, long is synonymous with int.
Therefore, DWORD is 32bit on a 32bit operating system. There is a separate define for a 64bit DWORD:
typdef unsigned _int64 DWORD64;
Hope that helps.
Use this CSS:
#container {
width: 400px;
border: 1px solid red;
}
#fixed {
position: fixed;
width: inherit;
border: 1px solid green;
}
The #fixed element will inherit it's parent width, so it will be 100% of that.
