I'm writing an OpenCL 1.2 backend for Tensorflow at https://github.com/hughperkins/tensorflow-cl
This fork of tensorflow for OpenCL has the following characteristics:
This is not the only OpenCL fork of Tensorflow available. There is also a fork being developed by Codeplay https://www.codeplay.com , using Computecpp, https://www.codeplay.com/products/computesuite/computecpp Their fork has stronger requirements than my own, as far as I know, in terms of which specific GPU devices it works on. You would need to check the Platform Support Notes (at the bottom of hte computecpp page), to determine whether your device is supported. The codeplay fork is actually an official Google fork, which is here: https://github.com/benoitsteiner/tensorflow-opencl

Here's how you might implement a counter:
counter=0
while true; do
if /home/hadoop/latest/bin/hadoop fs -ls /apps/hdtech/bds/quality-rt/dt=$DATE_YEST_FORMAT2 then
echo "Files Present" | mailx -s "File Present" -r [email protected] [email protected]
exit 0
elif [[ "$counter" -gt 20 ]]; then
echo "Counter: $counter times reached; Exiting loop!"
exit 1
else
counter=$((counter+1))
echo "Counter: $counter time(s); Sleeping for another half an hour" | mailx -s "Time to Sleep Now" -r [email protected] [email protected]
sleep 1800
fi
done
Some Explanations:
counter=$((counter+1))
- this is how you can increment a counter. The $
for counter
is optional inside the double parentheses in this case.elif [[ "$counter" -gt 20 ]]; then
- this checks whether $counter
is not greater than 20
. If so, it outputs the appropriate message and breaks out of your while loop.This works great for me:
WHERE CHARINDEX(CONVERT(nvarchar, CustNum), @CustNum) > 0
In my case it was because I was using a port other than the default port 80. I was able to access the site locally using localhost but not on another machine using the IP address.
To solve the issue I had to add a firewall inbound rule to allow the port.
The below regex will help to validate hh:mm format
^([0-1][0-9]|2[0-3]):[0-5][0-9]$
This error might be because of an attribute left empty in the manifest file.
An example:
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:logo="@drawable/ic_actionbar"
android:supportsRtl="true"
android:fullBackupContent="">
...
</application>
The fullBackupContent
is empty in the above example.
When it's changed to android:fullBackupContent="true"
it will be fixed.

A small function I made that can grab the string between, and can (optionally) skip a number of matched words to grab a specific index.
Also, setting start
to false
will use the beginning of the string, and setting end
to false
will use the end of the string.
set pos1
to the position of the start
text you want to use, 1
will use the first occurrence of start
pos2
does the same thing as pos1
, but for end
, and 1
will use the first occurrence of end
only after start
, occurrences of end
before start
are ignored.
function getStringBetween(str, start=false, end=false, pos1=1, pos2=1){
var newPos1 = 0;
var newPos2 = str.length;
if(start){
var loops = pos1;
var i = 0;
while(loops > 0){
if(i > str.length){
break;
}else if(str[i] == start[0]){
var found = 0;
for(var p = 0; p < start.length; p++){
if(str[i+p] == start[p]){
found++;
}
}
if(found >= start.length){
newPos1 = i + start.length;
loops--;
}
}
i++;
}
}
if(end){
var loops = pos2;
var i = newPos1;
while(loops > 0){
if(i > str.length){
break;
}else if(str[i] == end[0]){
var found = 0;
for(var p = 0; p < end.length; p++){
if(str[i+p] == end[p]){
found++;
}
}
if(found >= end.length){
newPos2 = i;
loops--;
}
}
i++;
}
}
var result = '';
for(var i = newPos1; i < newPos2; i++){
result += str[i];
}
return result;
}
On linux (debian 9) after resetting the mysql(Maria DB) root password, you just have to edit the phpmyadmin db config file located at /etc/phpmyadmin/config-db.php

Yahoo's api provides a CSV dump:
Example: http://finance.yahoo.com/d/quotes.csv?s=msft&f=price
I'm not sure if it is documented or not, but this code sample should showcase all of the features (namely the stat types [parameter f in the query string]. I'm sure you can find documentation (official or not) if you search for it.
http://www.goldb.org/ystockquote.html
Edit
I found some unofficial documentation:
Use my example...
public void createNotification() {
NotificationManager notificationManager = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon,
"message", System.currentTimeMillis());
// Hide the notification after its selected
notification.flags |= Notification.FLAG_AUTO_CANCEL;
Vibrator vibrator = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
long[] pattern = { 0, 100, 600, 100, 700};
vibrator.vibrate(pattern, -1);
Intent intent = new Intent(this, Main.class);
PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
String sms = getSharedPreferences("SMSPREF", MODE_PRIVATE).getString("incoming", "EMPTY");
notification.setLatestEventInfo(this, "message" ,
sms, activity);
notification.number += 1;
notificationManager.notify(0, notification);
}
Just use the rjust method of the string object.
This example will make a string of 10 characters long, padding as necessary.
>>> t = 'test'
>>> t.rjust(10, '0')
>>> '000000test'

A "JSON object" is actually an oxymoron. JSON is a text format describing an object, not an actual object, so data can either be in the form of JSON, or deserialised into an object.
The JSON for that would look like this:
{"KEY1":{"NAME":"XXXXXX","VALUE":100},"KEY2":{"NAME":"YYYYYYY","VALUE":200},"KEY3":{"NAME":"ZZZZZZZ","VALUE":500}}
Once you have parsed the JSON into a Javascript object (called data
in the code below), you can for example access the object for KEY2
and it's properties like this:
var obj = data.KEY2;
alert(obj.NAME);
alert(obj.VALUE);
If you have the key as a string, you can use index notation:
var key = 'KEY3';
var obj = data[key];
This is what worked for me using Explicit Wait from here WebDriver: Advanced Usage
public void checkAlert() {
try {
WebDriverWait wait = new WebDriverWait(driver, 2);
wait.until(ExpectedConditions.alertIsPresent());
Alert alert = driver.switchTo().alert();
alert.accept();
} catch (Exception e) {
//exception handling
}
}
David's solution is good. But I found the <script>alert(document.domain);</script>
in the page still alerts "localhost" because the Project Url is still localhost even if it has been override with http://dev.example.com
. Another issue I run into is that it alerts me the port 80 has already been in use even if I have disabled the Skype using the 80 port number as recommended by David Murdoch. So I have figured out another solution that is much easier:
http://localhost:33333/
), then change it from http://localhost:33333/
to http://mydomain:333333/
Note: After this change, you should neither click the "Create Virtual Directory" button on the right of the Project Url box nor click the Save button of the Visual Studio as they won't be succeeded. You can save your settings after next step 3.http://mydomain:333333/
, and <script>alert(document.domain);</script>
in the page will alert "mydomain".Note: The port number listed above is assumed to be 33333. You need to change it to the port number set by your visual studio.
Post edited: Today I tried with another domain name and got the following error: Unable to launch the IIS Express Web server. Failed to register URL... Access is denied. (0x80070005). I exit the IIS Express by right clicking the IIS Express icon at the right corner in the Windows task bar, and then re-start my visual studio as administrator, and the issue is gone.
A slightly modified version of Sophie's answer which allows to output the *.d files to a different folder (I will only paste the interesting part that generates the dependency files):
$(OBJDIR)/%.o: %.cpp
# Generate dependency file
mkdir -p $(@D:$(OBJDIR)%=$(DEPDIR)%)
$(CXX) $(CXXFLAGS) $(CPPFLAGS) -MM -MT $@ $< -MF $(@:$(OBJDIR)/%.o=$(DEPDIR)/%.d)
# Generate object file
mkdir -p $(@D)
$(CXX) $(CXXFLAGS) $(CPPFLAGS) -c $< -o $@
Note that the parameter
-MT $@
is used to ensure that the targets (i.e. the object file names) in the generated *.d files contain the full path to the *.o files and not just the file name.
I don't know why this parameter is NOT needed when using -MMD in combination with -c (as in Sophie's version). In this combination it seems to write the full path of the *.o files into the *.d files. Without this combination, -MMD also writes only the pure file names without any directory components into the *.d files. Maybe somebody knows why -MMD writes the full path when combined with -c. I have not found any hint in the g++ man page.
The problem was the table width. I had used width: 100%
for the table. The table columns are adjusted automatically after removing the width tag.
$routeProvider resolve property allows delaying of route change until data is loaded.
First define a route with resolve
attribute like this.
angular.module('phonecat', ['phonecatFilters', 'phonecatServices', 'phonecatDirectives']).
config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/phones', {
templateUrl: 'partials/phone-list.html',
controller: PhoneListCtrl,
resolve: PhoneListCtrl.resolve}).
when('/phones/:phoneId', {
templateUrl: 'partials/phone-detail.html',
controller: PhoneDetailCtrl,
resolve: PhoneDetailCtrl.resolve}).
otherwise({redirectTo: '/phones'});
}]);
notice that the resolve
property is defined on route.
function PhoneListCtrl($scope, phones) {
$scope.phones = phones;
$scope.orderProp = 'age';
}
PhoneListCtrl.resolve = {
phones: function(Phone, $q) {
// see: https://groups.google.com/forum/?fromgroups=#!topic/angular/DGf7yyD4Oc4
var deferred = $q.defer();
Phone.query(function(successData) {
deferred.resolve(successData);
}, function(errorData) {
deferred.reject(); // you could optionally pass error data here
});
return deferred.promise;
},
delay: function($q, $defer) {
var delay = $q.defer();
$defer(delay.resolve, 1000);
return delay.promise;
}
}
Notice that the controller definition contains a resolve object which declares things which should be available to the controller constructor. Here the phones
is injected into the controller and it is defined in the resolve
property.
The resolve.phones
function is responsible for returning a promise. All of the promises are collected and the route change is delayed until after all of the promises are resolved.

Basically you need to do two loops here. The one you are doing already is iterating each element in the 0th array element.
You have programs: [ {...}, {...} ] so programs[0] is { "name":"zonealarm", "price":"500" } So your loop is just going over that.
You could do an outer loop over the array
$.each(data.programs, function(index) {
// then loop over the object elements
$.each(data.programs[index], function(key, value) {
console.log(key + ": " + value);
}
}
You may use Request.Cookies collection to read the cookies.
if(Request.Cookies["key"]!=null)
{
var value=Request.Cookies["key"].Value;
}

In Java, the single operators &, |, ^, ! depend on the operands. If both operands are ints, then a bitwise operation is performed. If both are booleans, a "logical" operation is performed.
If both operands mismatch, a compile time error is thrown.
The double operators &&, || behave similarly to their single counterparts, but both operands must be conditional expressions, for example:
if (( a < 0 ) && ( b < 0 )) { ... } or similarly, if (( a < 0 ) || ( b < 0 )) { ... }

Tuples are compared position by position: the first item of the first tuple is compared to the first item of the second tuple; if they are not equal (i.e. the first is greater or smaller than the second) then that's the result of the comparison, else the second item is considered, then the third and so on.
See Common Sequence Operations:
Sequences of the same type also support comparisons. In particular, tuples and lists are compared lexicographically by comparing corresponding elements. This means that to compare equal, every element must compare equal and the two sequences must be of the same type and have the same length.
Also Value Comparisons for further details:
Lexicographical comparison between built-in collections works as follows:
- For two collections to compare equal, they must be of the same type, have the same length, and each pair of corresponding elements must compare equal (for example,
[1,2] == (1,2)
is false because the type is not the same).- Collections that support order comparison are ordered the same as their first unequal elements (for example,
[1,2,x] <= [1,2,y]
has the same value asx <= y
). If a corresponding element does not exist, the shorter collection is ordered first (for example,[1,2] < [1,2,3]
is true).
If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is considered smaller (for example, [1,2] < [1,2,3] returns True).
Note 1: <
and >
do not mean "smaller than" and "greater than" but "is before" and "is after": so (0, 1) "is before" (1, 0).
Note 2: tuples must not be considered as vectors in a n-dimensional space, compared according to their length.
Note 3: referring to question https://stackoverflow.com/questions/36911617/python-2-tuple-comparison: do not think that a tuple is "greater" than another only if any element of the first is greater than the corresponding one in the second.
You must change the cmake C/CXX default FLAGS .
According to CMAKE_BUILD_TYPE={DEBUG/MINSIZEREL/RELWITHDEBINFO/RELEASE}
put in the main CMakeLists.txt
one of :
For C
set(CMAKE_C_FLAGS_DEBUG "put your flags")
set(CMAKE_C_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_C_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_C_FLAGS_RELEASE "put your flags")
For C++
set(CMAKE_CXX_FLAGS_DEBUG "put your flags")
set(CMAKE_CXX_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_CXX_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_CXX_FLAGS_RELEASE "put your flags")
This will override the values defined in CMakeCache.txt
The below regex would match white spaces but not of a new line character.
(?:(?!\n)\s)
If you want to add carriage return also then add \r
with the |
operator inside the negative lookahead.
(?:(?![\n\r])\s)
Add +
after the non-capturing group to match one or more white spaces.
(?:(?![\n\r])\s)+
I don't know why you people failed to mention the POSIX character class [[:blank:]]
which matches any horizontal whitespaces (spaces and tabs). This POSIX chracter class would work on BRE(Basic REgular Expressions), ERE(Extended Regular Expression), PCRE(Perl Compatible Regular Expression).
You can use
RENAME TABLE `group` TO `member`;
Use back tick (`) instead of single quote (').
Because it's the size of an instance of the type - presumably enum values are stored as (32-bit / 4-byte) ints here.
I had the same problem shadow/elevation not showing on Android with elevation:2. Then i noticed that the view element is fool width, so I added margin:2 to the view element and elevation properly appeared.
Style:
margin: 2,
shadowColor: '#000',
shadowOffset: {
width: 0,
height: 1
},
shadowOpacity: 0.2,
shadowRadius: 1.41,
elevation: 2
You could use zip:
>>> lst=[[1,2,3],[11,12,13],[21,22,23]]
>>> zip(*lst)[0]
(1, 11, 21)
Or, Python 3 where zip
does not produce a list:
>>> list(zip(*lst))[0]
(1, 11, 21)
Or,
>>> next(zip(*lst))
(1, 11, 21)
Or, (my favorite) use numpy:
>>> import numpy as np
>>> a=np.array([[1,2,3],[11,12,13],[21,22,23]])
>>> a
array([[ 1, 2, 3],
[11, 12, 13],
[21, 22, 23]])
>>> a[:,0]
array([ 1, 11, 21])
Just discovered this:

SINGLE_BLOB
for varbinary(max)

Using CSS only, no. You need to use jQuery to add it.
Here is a helper function to achieve that:
/**
* Helper function to rename array keys.
*/
function _rename_arr_key($oldkey, $newkey, array &$arr) {
if (array_key_exists($oldkey, $arr)) {
$arr[$newkey] = $arr[$oldkey];
unset($arr[$oldkey]);
return TRUE;
} else {
return FALSE;
}
}
pretty based on @KernelM answer.
Usage:
_rename_arr_key('oldkey', 'newkey', $my_array);
It will return true on successful rename, otherwise false.
Set MYSQL timezone on server by logging to mysql server there set timezone value as required. For IST
SET SESSION time_zone = '+5:30';
Then run SELECT NOW();
Improving on the answer by @Alex, I suggest the following:
using (EventLog eventLog = new EventLog("Application"))
{
//You cannot be sure if the current identity has permissions to register the event source.
try
{
if (System.Web.HttpRuntime.AppDomainAppId != null)
{
eventLog.Source = System.Web.HttpRuntime.AppDomainAppId;
}
else
{
eventLog.Source = Process.GetCurrentProcess().ProcessName;
}
}
catch (SecurityException)
{
eventLog.Source = "Application";
}
eventLog.WriteEntry("Log message example", EventLogEntryType.Information, 1000);
}
It is important here not to specify category
parameter. If you do, and this is the same for the .NET Runtime
so-called magic, the
The description for Event ID <...> from source <...> cannot be found.
is going to appear.
I guess something like this would work:
Add System.ServiceProcess
to your project references (It's on the .NET tab).
using System.ServiceProcess;
ServiceController sc = new ServiceController(SERVICENAME);
switch (sc.Status)
{
case ServiceControllerStatus.Running:
return "Running";
case ServiceControllerStatus.Stopped:
return "Stopped";
case ServiceControllerStatus.Paused:
return "Paused";
case ServiceControllerStatus.StopPending:
return "Stopping";
case ServiceControllerStatus.StartPending:
return "Starting";
default:
return "Status Changing";
}
Edit: There is also a method sc.WaitforStatus()
that takes a desired status and a timeout, never used it but it may suit your needs.
Edit: Once you get the status, to get the status again you will need to call sc.Refresh()
first.
Reference: ServiceController object in .NET.
You mentioned using json2.js to stringify your data, but the POSTed data appears to be URLEncoded JSON You may have already seen it, but this post about the invalid JSON primitive covers why the JSON is being URLEncoded.
I'd advise against passing a raw, manually-serialized JSON string into your method. ASP.NET is going to automatically JSON deserialize the request's POST data, so if you're manually serializing and sending a JSON string to ASP.NET, you'll actually end up having to JSON serialize your JSON serialized string.
I'd suggest something more along these lines:
var markers = [{ "position": "128.3657142857143", "markerPosition": "7" },
{ "position": "235.1944023323615", "markerPosition": "19" },
{ "position": "42.5978231292517", "markerPosition": "-3" }];
$.ajax({
type: "POST",
url: "/webservices/PodcastService.asmx/CreateMarkers",
// The key needs to match your method's input parameter (case-sensitive).
data: JSON.stringify({ Markers: markers }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data){alert(data);},
error: function(errMsg) {
alert(errMsg);
}
});
The key to avoiding the invalid JSON primitive issue is to pass jQuery a JSON string for the data
parameter, not a JavaScript object, so that jQuery doesn't attempt to URLEncode your data.
On the server-side, match your method's input parameters to the shape of the data you're passing in:
public class Marker
{
public decimal position { get; set; }
public int markerPosition { get; set; }
}
[WebMethod]
public string CreateMarkers(List<Marker> Markers)
{
return "Received " + Markers.Count + " markers.";
}
You can also accept an array, like Marker[] Markers
, if you prefer. The deserializer that ASMX ScriptServices uses (JavaScriptSerializer) is pretty flexible, and will do what it can to convert your input data into the server-side type you specify.
This is not an answer to your question but I believe it is the solution to your problem. The interface org.springframework.data.repository.CrudRepository
does indeed have methods that return java.lang.Iterable
but you should not use this interface. Instead use sub interfaces, in your case org.springframework.data.mongodb.repository.MongoRepository
. This interface has methods that return objects of type java.util.List
.
EDIT: In summary, back in 2010 when this question was asked the most common way to solve this problem was to save a reference to the context where the setTimeout
function call is made, because setTimeout
executes the function with this
pointing to the global object:
var that = this;
if (this.options.destroyOnHide) {
setTimeout(function(){ that.tip.destroy() }, 1000);
}
In the ES5 spec, just released a year before that time, it introduced the bind
method, this wasn't suggested in the original answer because it wasn't yet widely supported and you needed polyfills to use it but now it's everywhere:
if (this.options.destroyOnHide) {
setTimeout(function(){ this.tip.destroy() }.bind(this), 1000);
}
The bind
function creates a new function with the this
value pre-filled.
Now in modern JS, this is exactly the problem arrow functions solve in ES6:
if (this.options.destroyOnHide) {
setTimeout(() => { this.tip.destroy() }, 1000);
}
Arrow functions do not have a this
value of its own, when you access it, you are accessing the this
value of the enclosing lexical scope.
HTML5 also standardized timers back in 2011, and you can pass now arguments to the callback function:
if (this.options.destroyOnHide) {
setTimeout(function(that){ that.tip.destroy() }, 1000, this);
}

method, and have the specified meta classes' __new__
method return an instance of the class, viola you have a "function" with methods.
Install-Package System.Drawing.Common
When a CSS property shows as struck-through, it means that the crossed-out style was applied, but then overridden by a more specific selector, a more local rule, or by a later property within the same rule.
(Special cases: a style will also be shown as struck-through if a style exists in an matching rule but is commented out, or if you've manually disabled it by unchecking it within the Chrome developer tools. It will also show as crossed out, but with an error icon, if the style has a syntax error.)
For example, if a background color was applied to all div
s, but a different background color was applied to div
s with a certain id, the first color will show up but will be crossed out, as the second color has replaced it (in the property list for the div
with that id).
In HTML:
<button type="button" id="AddButton" onclick="AddButtonClick()" class="btn btn-success btn-block ">Add</button>
In Jquery write this function:
function AddButtonClick(){
//change text from add to Update
$("#AddButton").text('Update');
}
Try setting host=127.0.0.1 on your db settings file, it worked for me! :)
Hope it helps!
May I suggest that you initialize your "max and min so far" variables not to infinity, but to the first number in the array?
If customer primary contact medium is email, if email is null then phonenumber, and if phonenumber is also null then address. It would be written using COALESCE as
coalesce(email,phonenumber,address)
while the same in hive can be achieved by chaining together nvl as
nvl(email,nvl(phonenumber,nvl(address,'n/a')))
tick_params is very useful for setting tick properties. Labels can be moved to the top with:
ax.tick_params(labelbottom=False,labeltop=True)
I had this issue on a Samsung device, Uninstalling the app gave the same message. The problem was that the app was also installed in the phone's "Secure Folder" area. Worth checking if this is your scenario.
I like to use Action in place of MethodInvoker, it is shorter and looks cleaner.
Invoke((Action)(() => {
DoSomething();
}));
// OR
Invoke((Action)delegate {
DoSomething();
});
Eg.
// Thread-safe update on a form control
public void DisplayResult(string text){
if (txtResult.InvokeRequired){
txtResult.Invoke((Action)delegate {
DisplayResult(text);
});
return;
}
txtResult.Text += text + "\r\n";
}
In the list view you can add android:listselector=color name that you want.
this work fine in my app.
Use:
dateTimePicker.Value.ToString("yyyy/MM/dd")
Refer to the following link:

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.
The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.
-Xmssize Specifies the initial heap size.
-Xmxsize Specifies the maximum heap size.
-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.
Sizes are expressed in bytes. Append the letter k
or K
to indicate kilobytes, m
or M
to indicate megabytes, g
or G
to indicate gigabytes.

You can very easily use this to re-use the value of the variable in another function.
// Use this in source window.var1= oEvent.getSource().getBindingContext();
// Get value of var1 in destination var var2= window.var1;
As Tmdean correctly pointed out you can use the Mid()
function. The MSDN Library also has a great reference section on VBScript which you can find here:
grep "pattern" <(head -n 10 filename)
Yahoo! Maps Web Services - Geocoding API accurately geocodes UK postcodes, unlike Google's API.

May be by:-
for(Row row : sheet) {
for(Cell cell : row) {
System.out.print(cell.getStringCellValue());
}
}
For specific type of cell you can try:
switch (cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
cellValue = cell.getStringCellValue();
break;
case Cell.CELL_TYPE_FORMULA:
cellValue = cell.getCellFormula();
break;
case Cell.CELL_TYPE_NUMERIC:
if (DateUtil.isCellDateFormatted(cell)) {
cellValue = cell.getDateCellValue().toString();
} else {
cellValue = Double.toString(cell.getNumericCellValue());
}
break;
case Cell.CELL_TYPE_BLANK:
cellValue = "";
break;
case Cell.CELL_TYPE_BOOLEAN:
cellValue = Boolean.toString(cell.getBooleanCellValue());
break;
}

I would recommend reviewing this page on How to Write Go Code
It documents both how to structure your project in a go build
friendly way, and also how to write tests. Tests do not need to be a cmd using the main
package. They can simply be TestX named functions as part of each package, and then go test
will discover them.
The structure suggested in that link in your question is a bit outdated, now with the release of Go 1. You no longer would need to place a pkg
directory under src
. The only 3 spec-related directories are the 3 in the root of your GOPATH: bin, pkg, src . Underneath src, you can simply place your project mypack
, and underneath that is all of your .go files including the mypack_test.go
go build
will then build into the root level pkg and bin.
So your GOPATH might look like this:
~/projects/
bin/
pkg/
src/
mypack/
foo.go
bar.go
mypack_test.go
export GOPATH=$HOME/projects
$ go build mypack
$ go test mypack
Update: as of >= Go 1.11, the Module system is now a standard part of the tooling and the GOPATH concept is close to becoming obsolete.
My case is I have a table like this
---------------------------------------------
|company_name|company_ID|CA | WA |
---------------------------------------------
|Costco | 1 |NULL | 2 |
---------------------------------------------
|Costco | 1 |3 |Null |
---------------------------------------------
And I want it to be like below:
---------------------------------------------
|company_name|company_ID|CA | WA |
---------------------------------------------
|Costco | 1 |3 | 2 |
---------------------------------------------
Most code is almost the same:
SELECT
FK,
MAX(CA) AS CA,
MAX(WA) AS WA
FROM
table1
GROUP BY company_name,company_ID
The only difference is the group by
, if you put two column names into it, you can group them in pairs.
public static T Runner<T>(Func<T> funcToRun)
{
//Do stuff before running function as normal
return funcToRun();
}
Usage:
var ReturnValue = Runner(() => GetUser(99));
When building apps for 32-bit or 64-bit platform (My experience is with Visual Studio 2010), don't rely on the Configuration Manager to set the correct platform for the executable. Even if the CM has x86 selected for the application, check the project properties (Build tab): it might still say "Any CPU" there. And if you run an "Any CPU" executable on a 64-bit platform, it will run in 64-bit mode and refuse to load your accompanying DLLs that were built for the x86 platform.
You need to have the System.Linq
namespace included in your view since Select is an extension method. You have a couple of options on how to do this:
Add @using System.Linq
to the top of your cshtml file.
If you find that you will be using this namespace often in many of your views, you can do this for all views by modifying the web.config inside of your Views folder (not the one at the root). You should see a pages/namespace XML element, create a new add
child that adds System.Linq. Here is an example:
<configuration>
<system.web.webPages.razor>
<pages>
<namespaces>
<add namespace="System.Linq" />
</namespaces>
</pages>
</system.web.webPages.razor>
</configuration>
ConcurrentLinkedQueue
uses a lock-free queue (based off the newer CAS instruction).
TextMate not for "advanced programmers". That does not make sense, TextMate contains everything an "advanced programmer" would want. It allows them to define a bundle that allows them to quickly set up the way they want their source code formatted, or one that follows the project guidelines, quick easy access to create entire structures and classes based on typing part of a construct and hitting tab.
TextMate is my tool of choice, it is fast, lightweight and yet contains all of the features I would want in a tool to program with. While it is not tightly integrated in Xcode, that is not a problem for me as I don't write software for Mac OS X. I write software for FreeBSD.
define class in models.py and a function in it.
class all_products(models.Model):
def get_all_products():
items = []
with open('EXACT FILE PATH OF YOUR CSV FILE','r') as fp:
# You can also put the relative path of csv file
# with respect to the manage.py file
reader1 = csv.reader(fp, delimiter=';')
for value in reader1:
items.append(value)
return items
You can access ith element in the list as items[i]
var queryObj = {};
if(url.split("?").length>0){
var queryString = url.split("?")[1];
}
now you have the query part in queryString
First replace will remove all the white spaces, second will replace all the '&' part with "," and finally the third replace will put ":" in place of '=' signs.
queryObj = JSON.parse('{"' + queryString.replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"') + '"}')
So let say you had a query like abc=123&efg=456. Now before parsing, your query is being converted into something like {"abc":"123","efg":"456"}. Now when you will parse this, it will give you your query in json object.
It requires a bit of rearranging, but when
does a good job to replace conditionals above. Here's the example from above written using the declarative syntax. Note that test3
stage is now two different stages. One that runs on the master branch and one that runs on anything else.
stage ('Test 3: Master') {
when { branch 'master' }
steps {
echo 'I only execute on the master branch.'
}
}
stage ('Test 3: Dev') {
when { not { branch 'master' } }
steps {
echo 'I execute on non-master branches.'
}
}
I was making a drop-down menu for a language selector - but I needed the dropdown menu to display the current language upon page load. I would either be getting my initial language from a URL param example.com?user_language=fr
, or detecting it from the user’s browser settings. Then when the user interacted with the dropdown, the selected language would be updated and the language selector dropdown would display the currently selected language.
In the spirit of the other answers using food examples, I got all sorts of fruit goodness for you.
First up, answering the initially asked question with a basic React functional component - two examples with and without props, then how to import the component elsewhere.
Next up, the same example - but juiced up with Typescript.
Then a bonus finale - A language selector dropdown component using Typescript.
FruitSelectDropdown
, one without props & one with accepting props fruitDetector
import React, { useState } from 'react'
export const FruitSelectDropdown = () => {
const [currentFruit, setCurrentFruit] = useState('oranges')
const changeFruit = (newFruit) => {
setCurrentFruit(newFruit)
}
return (
<form>
<select
onChange={(event) => changeFruit(event.target.value)}
value={currentFruit}
>
<option value="apples">Red Apples</option>
<option value="oranges">Outrageous Oranges</option>
<option value="tomatoes">Technically a Fruit Tomatoes</option>
<option value="bananas">Bodacious Bananas</option>
</select>
</form>
)
}
Or you can have FruitSelectDropdown accept props, maybe you have a function that outputs a string, you can pass it through using the fruitDetector
prop
import React, { useState } from 'react'
export const FruitSelectDropdown = ({ fruitDetector }) => {
const [currentFruit, setCurrentFruit] = useState(fruitDetector)
const changeFruit = (newFruit) => {
setCurrentFruit(newFruit)
}
return (
<form>
<select
onChange={(event) => changeFruit(event.target.value)}
value={currentFruit}
>
<option value="apples">Red Apples</option>
<option value="oranges">Outrageous Oranges</option>
<option value="tomatoes">Technically a Fruit Tomatoes</option>
<option value="bananas">Bodacious Bananas</option>
</select>
</form>
)
}
Then import the FruitSelectDropdown
elsewhere in your app
import React from 'react'
import { FruitSelectDropdown } from '../path/to/FruitSelectDropdown'
const App = () => {
return (
<div className="page-container">
<h1 className="header">A webpage about fruit</h1>
<div className="section-container">
<h2>Pick your favorite fruit</h2>
<FruitSelectDropdown fruitDetector='bananas' />
</div>
</div>
)
}
export default App
FruitSelectDropdown
with Typescriptimport React, { FC, useState } from 'react'
type FruitProps = {
fruitDetector: string;
}
export const FruitSelectDropdown: FC<FruitProps> = ({ fruitDetector }) => {
const [currentFruit, setCurrentFruit] = useState(fruitDetector)
const changeFruit = (newFruit: string): void => {
setCurrentFruit(newFruit)
}
return (
<form>
<select
onChange={(event) => changeFruit(event.target.value)}
value={currentFruit}
>
<option value="apples">Red Apples</option>
<option value="oranges">Outrageous Oranges</option>
<option value="tomatoes">Technically a Fruit Tomatoes</option>
<option value="bananas">Bodacious Bananas</option>
</select>
</form>
)
}
Then import the FruitSelectDropdown
elsewhere in your app
import React, { FC } from 'react'
import { FruitSelectDropdown } from '../path/to/FruitSelectDropdown'
const App: FC = () => {
return (
<div className="page-container">
<h1 className="header">A webpage about fruit</h1>
<div className="section-container">
<h2>Pick your favorite fruit</h2>
<FruitSelectDropdown fruitDetector='bananas' />
</div>
</div>
)
}
export default App
import React, { FC, useState } from 'react'
import { useTranslation } from 'react-i18next'
export const LanguageSelectDropdown: FC = () => {
const { i18n } = useTranslation()
const i18nLanguage = i18n.language
const [currentI18nLanguage, setCurrentI18nLanguage] = useState(i18nLanguage)
const changeLanguage = (language: string): void => {
i18n.changeLanguage(language)
setCurrentI18nLanguage(language)
}
return (
<form>
<select
onChange={(event) => changeLanguage(event.target.value)}
value={currentI18nLanguage}
>
<option value="en">English</option>
<option value="de">Deutsch</option>
<option value="es">Español</option>
<option value="fr">Français</option>
</select>
</form>
)
}
You can also try issuing the command while in your home directory.
Simple use .filter()
[docs] (AND) using the multiple selector [docs] (OR):
$('[myc="blue"]').filter('[myid="1"],[myid="2"]');
In general, chaining selectors, like a.foo.bar[attr=value]
is some kind of AND selector.
jQuery has extensive documentation about the supported selectors, it's worth a read.
As @Ansgar mentioned, [[
is a bashism, ie built into Bash and not available for other shells. If you want your script to be portable, use [
. Comparisons will also need a different syntax: change ==
to =
.
I had just upgraded to VS 2013 from VS 2012 and the current user identity (HttpContext.User.Identity) was coming through as anonymous.
I tried changing the IIS express applicationhost.config, no difference.
The solution was to look at the properties of the web project, hit F4 to get the project properties when you have the top level of the project selected. Do not right click on the project and select properties, this is something entirely different.
Change Anonymous Authentication to be Disabled and Windows Authentication to be Enabled.

Simple solution:
/\s{2,}/
This matches all occurrences of one or more whitespace characters. If you need to match the entire line, but only if it contains two or more consecutive whitespace characters:
/^.*\s{2,}.*$/
If the whitespaces don't need to be consecutive:
/^(.*\s.*){2,}$/

I wanted to ask the same question. Here is my current solution to obtain a string like this: 2013-02-07 09:24:40.749355372
I am not sure if there is a more straight forward solution than this, but at least the string format is freely configurable with this approach.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#define NANO 1000000000L
// buf needs to store 30 characters
int timespec2str(char *buf, uint len, struct timespec *ts) {
int ret;
struct tm t;
tzset();
if (localtime_r(&(ts->tv_sec), &t) == NULL)
return 1;
ret = strftime(buf, len, "%F %T", &t);
if (ret == 0)
return 2;
len -= ret - 1;
ret = snprintf(&buf[strlen(buf)], len, ".%09ld", ts->tv_nsec);
if (ret >= len)
return 3;
return 0;
}
int main(int argc, char **argv) {
clockid_t clk_id = CLOCK_REALTIME;
const uint TIME_FMT = strlen("2012-12-31 12:59:59.123456789") + 1;
char timestr[TIME_FMT];
struct timespec ts, res;
clock_getres(clk_id, &res);
clock_gettime(clk_id, &ts);
if (timespec2str(timestr, sizeof(timestr), &ts) != 0) {
printf("timespec2str failed!\n");
return EXIT_FAILURE;
} else {
unsigned long resol = res.tv_sec * NANO + res.tv_nsec;
printf("CLOCK_REALTIME: res=%ld ns, time=%s\n", resol, timestr);
return EXIT_SUCCESS;
}
}
output:

Try this:
subset(studentdata, Drink=='water')
that should do it.

For those like me who are brand new to this, here is code with const and an actual way to compare the byte[]'s. I got all of this code from stackoverflow but defined consts so values could be changed and also
// 24 = 192 bits
private const int SaltByteSize = 24;
private const int HashByteSize = 24;
private const int HasingIterationsCount = 10101;
public static string HashPassword(string password)
{
// http://stackoverflow.com/questions/19957176/asp-net-identity-password-hashing
byte[] salt;
byte[] buffer2;
if (password == null)
{
throw new ArgumentNullException("password");
}
using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, SaltByteSize, HasingIterationsCount))
{
salt = bytes.Salt;
buffer2 = bytes.GetBytes(HashByteSize);
}
byte[] dst = new byte[(SaltByteSize + HashByteSize) + 1];
Buffer.BlockCopy(salt, 0, dst, 1, SaltByteSize);
Buffer.BlockCopy(buffer2, 0, dst, SaltByteSize + 1, HashByteSize);
return Convert.ToBase64String(dst);
}
public static bool VerifyHashedPassword(string hashedPassword, string password)
{
byte[] _passwordHashBytes;
int _arrayLen = (SaltByteSize + HashByteSize) + 1;
if (hashedPassword == null)
{
return false;
}
if (password == null)
{
throw new ArgumentNullException("password");
}
byte[] src = Convert.FromBase64String(hashedPassword);
if ((src.Length != _arrayLen) || (src[0] != 0))
{
return false;
}
byte[] _currentSaltBytes = new byte[SaltByteSize];
Buffer.BlockCopy(src, 1, _currentSaltBytes, 0, SaltByteSize);
byte[] _currentHashBytes = new byte[HashByteSize];
Buffer.BlockCopy(src, SaltByteSize + 1, _currentHashBytes, 0, HashByteSize);
using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, _currentSaltBytes, HasingIterationsCount))
{
_passwordHashBytes = bytes.GetBytes(SaltByteSize);
}
return AreHashesEqual(_currentHashBytes, _passwordHashBytes);
}
private static bool AreHashesEqual(byte[] firstHash, byte[] secondHash)
{
int _minHashLength = firstHash.Length <= secondHash.Length ? firstHash.Length : secondHash.Length;
var xor = firstHash.Length ^ secondHash.Length;
for (int i = 0; i < _minHashLength; i++)
xor |= firstHash[i] ^ secondHash[i];
return 0 == xor;
}
In in your custom ApplicationUserManager, you set the PasswordHasher property the name of the class which contains the above code.
You want the --stat
option of git diff
, or if you're looking to parse this in a script, the --numstat
option.
git diff --stat <commit-ish> <commit-ish>
--stat
produces the human-readable output you're used to seeing after merges; --numstat
produces a nice table layout that scripts can easily interpret.
I somehow missed that you were looking to do this on multiple commits at the same time - that's a task for git log
. Ron DeVera touches on this, but you can actually do a lot more than what he mentions. Since git log
internally calls the diff machinery in order to print requested information, you can give it any of the diff stat options - not just --shortstat
. What you likely want to use is:
git log --author="Your name" --stat <commit1>..<commit2>
but you can use --numstat
or --shortstat
as well. git log
can also select commits in a variety other ways - have a look at the documentation. You might be interested in things like --since
(rather than specifying commit ranges, just select commits since last week) and --no-merges
(merge commits don't actually introduce changes), as well as the pretty output options (--pretty=oneline, short, medium, full...
).
Here's a one-liner to get total changes instead of per-commit changes from git log (change the commit selection options as desired - this is commits by you, from commit1 to commit2):
git log --numstat --pretty="%H" --author="Your Name" commit1..commit2 | awk 'NF==3 {plus+=$1; minus+=$2} END {printf("+%d, -%d\n", plus, minus)}'
(you have to let git log print some identifying information about the commit; I arbitrarily chose the hash, then used awk to only pick out the lines with three fields, which are the ones with the stat information)
open file, save as .csv and then apply
df = pd.read_csv('apps.csv', sep='\t')
for any other format also, just change the sep tag
As with most things you should pick which to use based on the context and what is conceptually the correct way to go. A switch is really saying "pick one of these based on this variables value" but an if statement is just a series of boolean checks.
As an example, if you were doing:
int value = // some value
if (value == 1) {
doThis();
} else if (value == 2) {
doThat();
} else {
doTheOther();
}
This would be much better represented as a switch as it then makes it immediately obviously that the choice of action is occurring based on the value of "value" and not some arbitrary test.
Also, if you find yourself writing switches and if-elses and using an OO language you should be considering getting rid of them and using polymorphism to achieve the same result if possible.
Finally, regarding switch taking longer to type, I can't remember who said it but I did once read someone ask "is your typing speed really the thing that affects how quickly you code?" (paraphrased)
Another example; using JavaScript to set a selected option.
(You could use this example to for loop an array of values into a drop down component)
<select id="yourDropDownElementId"><select/>
// Get the select element
var select = document.getElementById("yourDropDownElementId");
// Create a new option element
var el = document.createElement("option");
// Add our value to the option
el.textContent = "Example Value";
el.value = "Example Value";
// Set the option to selected
el.selected = true;
// Add the new option element to the select element
select.appendChild(el);
In the majority of cases you would use:
elem != null
Unlike a simple if (elem)
, it allows 0
, false
, NaN
and ''
, but rejects null
or undefined
, making it a good, general test for the presence of an argument, or property of an object.
The other checks are not incorrect either, they just have different uses:
if (elem)
: can be used if elem
is guaranteed to be an object, or if false
, 0
, etc. are considered "default" values (hence equivalent to undefined
or null
).
typeof elem == 'undefined'
can be used in cases where a specified null
has a distinct meaning to an uninitialised variable or property.
elem
is not declared (i.e. no var
statement, not a property of window
, or not a function argument). This is, in my opinion, rather dangerous as it allows typos to slip by unnoticed. To avoid this, see the below method.Also useful is a strict comparison against undefined
:
if (elem === undefined) ...
However, because the global undefined
can be overridden with another value, it is best to declare the variable undefined
in the current scope before using it:
var undefined; // really undefined
if (elem === undefined) ...
Or:
(function (undefined) {
if (elem === undefined) ...
})();
A secondary advantage of this method is that JS minifiers can reduce the undefined
variable to a single character, saving you a few bytes every time.
If you mean lists, try ==
:
l1 = [1,2,3]
l2 = [1,2,3,4]
l1 == l2 # False
If you mean array
:
l1 = array('l', [1, 2, 3])
l2 = array('d', [1.0, 2.0, 3.0])
l1 == l2 # True
l2 = array('d', [1.0, 2.0, 3.0, 4.0])
l1 == l2 # False
If you want to compare strings (per your comment):
date_string = u'Thu Sep 16 13:14:15 CDT 2010'
date_string2 = u'Thu Sep 16 14:14:15 CDT 2010'
date_string == date_string2 # False
I modified the solution by @Kalyani and so far it's been working beautifully!
$('selector').click(function(event) {
if(!event.detail || event.detail == 1){ return true; }
else { return false; }
});
Use sudo pip3 install jupyter
for installing jupyter for python3 and sudo pip install jupyter
for installing jupyter notebook for python2. Then, you can call ipython kernel install
command to enable both types of notebook to choose from in jupyter notebook.
In addition to Harry's answer, I think it's crucial to add/emphasize that :last-child will not work if the element is not the VERY LAST element in a container. For whatever reason it took me hours to realize that, and even though Harry's answer is very thorough I couldn't extract that information from "The last-child selector is used to select the last child element of a parent."
Suppose this is my selector: a:last-child {}
This works:
<div>
<a></a>
<a>This will be selected</a>
</div>
This doesn't:
<div>
<a></a>
<a>This will no longer be selected</a>
<div>This is now the last child :'( </div>

It doesn't because the a
element is not the last element inside its parent.
It may be obvious, but it was not for me...
N.B. - this question and answer relate to the 2000 version of SQL Server. In later versions, the restriction on INSERT INTO @table_variable ... EXEC ...
were lifted and so it doesn't apply for those later versions.
You'll have to switch to a temp table:
CREATE TABLE #tmp (code varchar(50), mount money)
DECLARE @q nvarchar(4000)
SET @q = 'SELECT coa_code, amount FROM T_Ledger_detail'
INSERT INTO #tmp (code, mount)
EXEC sp_executesql (@q)
SELECT * from #tmp
From the documentation:
A table variable behaves like a local variable. It has a well-defined scope, which is the function, stored procedure, or batch in which it is declared.
Within its scope, a table variable may be used like a regular table. It may be applied anywhere a table or table expression is used in SELECT, INSERT, UPDATE, and DELETE statements. However, table may not be used in the following statements:
INSERT INTO table_variable EXEC stored_procedure
SELECT select_list INTO table_variable statements.
import Foundation
var string = NSString(data: NSData?, encoding: UInt)
Using the new nested query syntax
with q(name, id, parent_id, parent_name) as (
select
t1.name, t1.id,
null as parent_id, null as parent_name
from t1
where t1.id = 1
union all
select
t1.name, t1.id,
q.id as parent_id, q.name as parent_name
from t1, q
where t1.parent_id = q.id
)
select * from q
The Array prototype's reverse method modifies the array and returns a reference to it, which means you can do this:
var sortedAsc = _.sortBy(collection, 'propertyName');
var sortedDesc = _.sortBy(collection, 'propertyName').reverse();
Also, the underscore documentation reads:
In addition, the Array prototype's methods are proxied through the chained Underscore object, so you can slip a
reverse
or apush
into your chain, and continue to modify the array.
which means you can also use .reverse()
while chaining:
var sortedDescAndFiltered = _.chain(collection)
.sortBy('propertyName')
.reverse()
.filter(_.property('isGood'))
.value();

If text file is not being read, try using a more closer absolute path (if you wish you could use complete absolute path,) like this:
FileInputStream fin=new FileInputStream("\\Dash\\src\\RS\\Test.txt");
assume that the absolute path is:
C:\\Folder1\\Folder2\\Dash\\src\\RS\\Test.txt
Here's how you could set a custom cookie value for the request:
var baseAddress = new Uri("http://example.com");
var cookieContainer = new CookieContainer();
using (var handler = new HttpClientHandler() { CookieContainer = cookieContainer })
using (var client = new HttpClient(handler) { BaseAddress = baseAddress })
{
var content = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("foo", "bar"),
new KeyValuePair<string, string>("baz", "bazinga"),
});
cookieContainer.Add(baseAddress, new Cookie("CookieName", "cookie_value"));
var result = await client.PostAsync("/test", content);
result.EnsureSuccessStatusCode();
}
Here is a quickly hacked up version of this using SVG I just did. Works well for me on my iPhone. Also works in a desktop browser using normal mouse events.
The answer by Nils describes how to convert objects to maps, which I found very useful. However, the OP was also wondering where this information is in the MDN docs. While it may not have been there when the question was originally asked, it is now on the MDN page for Object.entries() under the heading Converting an Object to a Map which states:
Converting an Object to a Map
The
new Map()
constructor accepts an iterable ofentries
. WithObject.entries
, you can easily convert fromObject
toMap
:const obj = { foo: 'bar', baz: 42 }; const map = new Map(Object.entries(obj)); console.log(map); // Map { foo: "bar", baz: 42 }
If you are really about to work on multi-gigabyte text files then do not use PowerShell. Even if you find a way to read it faster processing of huge amount of lines will be slow in PowerShell anyway and you cannot avoid this. Even simple loops are expensive, say for 10 million iterations (quite real in your case) we have:
# "empty" loop: takes 10 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) {} }
# "simple" job, just output: takes 20 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) { $i } }
# "more real job": 107 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) { $i.ToString() -match '1' } }
UPDATE: If you are still not scared then try to use the .NET reader:
$reader = [System.IO.File]::OpenText("my.log")
try {
for() {
$line = $reader.ReadLine()
if ($line -eq $null) { break }
# process the line
$line
}
}
finally {
$reader.Close()
}
UPDATE 2
There are comments about possibly better / shorter code. There is nothing wrong with the original code with for
and it is not pseudo-code. But the shorter (shortest?) variant of the reading loop is
$reader = [System.IO.File]::OpenText("my.log")
while($null -ne ($line = $reader.ReadLine())) {
$line
}
In windows this worked for me
git config --global http.sslVerify false
you forgot to add this in your function : change to this :
<input type="button" value="ahaha" onclick="$(this).MessageBox('msg');" />
find the below explanation:
int main()
{
int a = 10;// say address of 'a' is 2000;
int *p = &a; //it means 'p' is pointing[referencing] to 'a'. i.e p->2000
int c = *p; //*p means dereferncing. it will give the content of the address pointed by 'p'. in this case 'p' is pointing to 2000[address of 'a' variable], content of 2000 is 10. so *p will give 10.
}
conclusion :
&
[address operator] is used for referencing.*
[star operator] is used for de-referencing .I launched ubuntu Xampp server on AWS amazon. And met the same problem with FTP, even though add user to group ftp SFTP and set permissions, owner group of htdocs folder. Finally find the reason in inbound rules in security group, added All TCP, 0 - 65535 rule(0.0.0.0/0,::/0) , then working right!
When to use LIBXML_NOCDATA
?
I add the issue when transforming XML to JSON.
$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>");
echo json_encode($xml, true);
/* prints
{
"content": {}
}
*/
When accessing the SimpleXMLElement object, It gets the CDATA :
$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>");
echo $xml->content;
/* prints
Hello, world!
*/
I makes sense to use LIBXML_NOCDATA
because json_encode
don't access the SimpleXMLElement to trigger the string casting feature, I'm guessing a __toString()
equivalent.
$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>", null, LIBXML_NOCDATA);
echo json_encode($xml);
/*
{
"content": "Hello, world!"
}
*/
You can also do this to set a header for all future gets for the Session object, where x-test will be in all s.get() calls:
s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})
# both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})
from: http://docs.python-requests.org/en/latest/user/advanced/#session-objects
Use an image editor to cut out a portion of the background, then apply CSS's background-repeat property to make the small image fill the area where it is used.
In some cases, background-repeat creates seams where the image repeats. A solution is to use an image editor as follows: starting with the background image, copy the image, flip (mirror, not rotate) the copy left-to-right, and paste it to the right edge of the original, overlapping 1 pixel. Crop to remove 1 pixel from the right edge of the combined image. Now repeat for the vertical: copy the combined image, flip the copy top-to-bottom, paste it to the bottom of the combined, overlapping one pixel. Crop to remove 1 pixel from the bottom. The resulting image should be seam-free.
You can use DecimalFormat, but please also note that it is not a good idea to use double in these situations, rather use BigDecimal
Use scipy's Rotation.from_rotvec()
. The argument is the rotation vector (a unit vector) multiplied by the rotation angle in rads.
from scipy.spatial.transform import Rotation
from numpy.linalg import norm
v = [3, 5, 0]
axis = [4, 4, 1]
theta = 1.2
axis = axis / norm(axis) # normalize the rotation vector first
rot = Rotation.from_rotvec(theta * axis)
new_v = rot.apply(v)
print(new_v) # results in [2.74911638 4.77180932 1.91629719]
There are several more ways to use Rotation
based on what data you have about the rotation:
from_quat
Initialized from quaternions.
from_dcm
Initialized from direction cosine matrices.
from_euler
Initialized from Euler angles.
Off-topic note: One line code is not necessarily better code as implied by some users.
The best reusable option is to implement the interface Iterable and override the method iterator().
Here's an example of a an ArrayList like class implementing the interface, in which you override the method Iterator().
import java.util.Iterator;
public class SOList<Type> implements Iterable<Type> {
private Type[] arrayList;
private int currentSize;
public SOList(Type[] newArray) {
this.arrayList = newArray;
this.currentSize = arrayList.length;
}
@Override
public Iterator<Type> iterator() {
Iterator<Type> it = new Iterator<Type>() {
private int currentIndex = 0;
@Override
public boolean hasNext() {
return currentIndex < currentSize && arrayList[currentIndex] != null;
}
@Override
public Type next() {
return arrayList[currentIndex++];
}
@Override
public void remove() {
throw new UnsupportedOperationException();
}
};
return it;
}
}
This class implements the Iterable interface using Generics. Considering you have elements to the array, you will be able to get an instance of an Iterator, which is the needed instance used by the "foreach" loop, for instance.
You can just create an anonymous instance of the iterator without creating extending Iterator and take advantage of the value of currentSize to verify up to where you can navigate over the array (let's say you created an array with capacity of 10, but you have only 2 elements at 0 and 1). The instance will have its owner counter of where it is and all you need to do is to play with hasNext(), which verifies if the current value is not null, and the next(), which will return the instance of your currentIndex. Below is an example of using this API...
public static void main(String[] args) {
// create an array of type Integer
Integer[] numbers = new Integer[]{1, 2, 3, 4, 5};
// create your list and hold the values.
SOList<Integer> stackOverflowList = new SOList<Integer>(numbers);
// Since our class SOList is an instance of Iterable, then we can use it on a foreach loop
for(Integer num : stackOverflowList) {
System.out.print(num);
}
// creating an array of Strings
String[] languages = new String[]{"C", "C++", "Java", "Python", "Scala"};
// create your list and hold the values using the same list implementation.
SOList<String> languagesList = new SOList<String>(languages);
System.out.println("");
// Since our class SOList is an instance of Iterable, then we can use it on a foreach loop
for(String lang : languagesList) {
System.out.println(lang);
}
}
// will print "12345
//C
//C++
//Java
//Python
//Scala
If you want, you can iterate over it as well using the Iterator instance:
// navigating the iterator
while (allNumbers.hasNext()) {
Integer value = allNumbers.next();
if (allNumbers.hasNext()) {
System.out.print(value + ", ");
} else {
System.out.print(value);
}
}
// will print 1, 2, 3, 4, 5
The foreach documentation is located at http://download.oracle.com/javase/1,5.0/docs/guide/language/foreach.html. You can take a look at a more complete implementation at my personal practice google code.
Now, to get the effects of what you need I think you need to plug a concept of a filter in the Iterator... Since the iterator depends on the next values, it would be hard to return true on hasNext(), and then filter the next() implementation with a value that does not start with a char "a" for instance. I think you need to play around with a secondary Interator based on a filtered list with the values with the given filter.
I have this working well using JPA2.0 and MySQL 5.5.10, for cases where I only care about the last time the row was modified. MySQL will create a timestamp on first insertion, and every time UPDATE is called on the row. (NOTE: this will be problematic if I cared whether or not the UPDATE actually made a change).
The "timestamp" column in this example is like a "last-touched" column.x`
The code below uses a separate column "version" for optimistic locking.
private long version;
private Date timeStamp
@Version
public long getVersion() {
return version;
}
public void setVersion(long version) {
this.version = version;
}
// columnDefinition could simply be = "TIMESTAMP", as the other settings are the MySQL default
@Column(name="timeStamp", columnDefinition="TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP")
@Temporal(TemporalType.TIMESTAMP)
public Date getTimeStamp() {
return timeStamp;
}
public void setTimeStamp(Date timeStamp) {
this.timeStamp = timeStamp;
}
(NOTE: @Version doesn't work on a MySQL "DATETIME" column, where the attribute type is "Date" in the Entity class. This was because Date was generating a value down to the millisecond, however MySQL was not storing the millisecond, so when it did a comparison between what was in the database, and the "attached" entity, it thought they had different version numbers)
From the MySQL manual regarding TIMESTAMP :
With neither DEFAULT nor ON UPDATE clauses, it is the same as DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP.
There are such of ways to Bind a Placeholder to View:
1) With use of MVC Data Annotations:
Model:
[Required]
[Display(Prompt = "Enter Your First Name")]
public string FirstName { get; set; }
Razor Syntax:
@Html.TextBoxFor(m => m.FirstName, new { placeholder = @Html.DisplayNameFor(n => n.UserName)})
2) With use of MVC Data Annotations But with DisplayName:
Model:
[Required]
[DisplayName("Enter Your First Name")]
public string FirstName { get; set; }
Razor Syntax:
@Html.TextBoxFor(m => m.FirstName, new { placeholder = @Html.DisplayNameFor(n => n.UserName)})
3) Without use of MVC Data Annotation (recommended):
Razor Syntax:
@Html.TextBoxFor(m => m.FirstName, new { @placeholder = "Enter Your First Name")
Even if the question is old, a more accurate answer about Management Studio would be required.
You can create the column manually or with Management Studio. But Management Studio will require to recreate the table and will result in a time out if you have too much data in it already, avoid unless the table is light.
To change the order of the columns you simply need to move them around in Management Studio. This should not require (Exceptions most likely exists) that Management Studio to recreate the table since it most likely change the ordination of the columns in the table definitions.
I've done it this way on numerous occasion with tables that I could not add columns with the GUI because of the data in them. Then moved the columns around with the GUI of Management Studio and simply saved them.
You will go from an assured time out to a few seconds of waiting.
I made use of sendkeys in shell scripting using a vbsscript file. Below is the code in vbs file,
Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.SendKeys "C:\Demo.txt"
WshShell.SendKeys "{ENTER}"
Below is the selenium code line to run this vbs file,
driver.findElement(By.id("uploadname1")).click();
Thread.sleep(1000);
Runtime.getRuntime().exec( "wscript C:/script.vbs" );
I prefer to limit the number of retries, so that if there's a problem with that specific item you will eventually continue onto the next one, thus:
for i in range(100):
for attempt in range(10):
try:
# do thing
except:
# perhaps reconnect, etc.
else:
break
else:
# we failed all the attempts - deal with the consequences.
I took a list and used,
!MyList.Contains(table.columb.tostring())
Note: Make sure to use List and not Ilist
I've made a category from @Abizern answer

NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData options:NSJSONReadingMutableContainers error:&error];
return (!json ? nil : json);
}

Use it like this,
NSString *jsonString = @"{\"2\":\"3\"}";
NSLog(@"%@",[jsonString json_StringToDictionary]);

There's a few things that could get in the way - is your data clean?
It could be that you have spaces at the end of the first name field, which then means you have two spaces between the firstname and lastname when you concat them? Using trim(first_name)/trim(last_name) will fix this - although the real fix is to update your data.
You could also this to match where two words both occur but not necessarily together (assuming you are in php - which the $search_term variable suggests you are)
$whereclauses=array();
$terms = explode(' ', $search_term);
foreach ($terms as $term) {
$term = mysql_real_escape_string($term);
$whereclauses[] = "CONCAT(first_name, ' ', last_name) LIKE '%$term%'";
}
$sql = "select * from table where";
$sql .= implode(' and ', $whereclauses);

If you want to disable all the div's controls, you can try adding a transparent div on the div to disable, you gonna make it unclickable, also use fadeTo to create a disable appearance.
try this.
$('#DisableDiv').fadeTo('slow',.6);

Making it invisible with visibility still makes it use up space. Rather try set the display to none to make it invisible, and then set the display to block to make it visible.

If a <script>
has a src
then the text content of the element will be not be executed as JS (although it will appear in the DOM).
You need to use multiple script elements.
<script>
to load the external scripta <script>
to hold your inline code (with the call to the function in the external script)
var x : IHash = {};
x['key1'] = 'value1';
x['key2'] = 'value2';
console.log(x['key1']);
// outputs value1
console.log(x['key2']);
// outputs value2
If you would like to then iterate through your dictionary, you can use.
Object.keys(x).forEach((key) => {console.log(x[key])});
Object.keys returns all the properties of an object, so it works nicely for returning all the values from dictionary styled objects.
You also mentioned a hashmap in your question, the above definition is for a dictionary style interface. Therefore the keys will be unique, but the values will not.
You could use it like a hashset by just assigning the same value to the key and its value.
if you wanted the keys to be unique and with potentially different values, then you just have to check if the key exists on the object before adding to it.
var valueToAdd = 'one';
if(!x[valueToAdd])
x[valueToAdd] = valueToAdd;
or you could build your own class to act as a hashset of sorts.
Class HashSet{
private var keys: IHash = {};
private var values: string[] = [];
public Add(key: string){
if(!keys[key]){
values.push(key);
keys[key] = key;
}
}
public GetValues(){
// slicing the array will return it by value so users cannot accidentally
// start playing around with your array
return values.slice();
}
}

Just for the reference, if you work in scripts (batch processing), not in stored procedure, flushing output is triggered by the GO command, e.g.
print 'test'
print 'test'
go
In general, my conclusion is following: output of mssql script execution, executing in SMS GUI or with sqlcmd.exe, is flushed to file, stdoutput, gui window on first GO statement or until the end of the script.
Flushing inside of stored procedure functions differently, since you can not place GO inside.

I personally use the helper class which supports generics (Swift 3, 4.x compatible)
struct Rescale<Type : BinaryFloatingPoint> {
typealias RescaleDomain = (lowerBound: Type, upperBound: Type)
var fromDomain: RescaleDomain
var toDomain: RescaleDomain
init(from: RescaleDomain, to: RescaleDomain) {
self.fromDomain = from
self.toDomain = to
}
func interpolate(_ x: Type ) -> Type {
return self.toDomain.lowerBound * (1 - x) + self.toDomain.upperBound * x;
}
func uninterpolate(_ x: Type) -> Type {
let b = (self.fromDomain.upperBound - self.fromDomain.lowerBound) != 0 ? self.fromDomain.upperBound - self.fromDomain.lowerBound : 1 / self.fromDomain.upperBound;
return (x - self.fromDomain.lowerBound) / b
}
func rescale(_ x: Type ) -> Type {
return interpolate( uninterpolate(x) )
}
}
Ex:
let rescaler = Rescale<Float>(from: (-1, 1), to: (0, 100))
print(rescaler.rescale(0)) // OUTPUT: 50
There is none when it comes to file extensions. Your bundler/transpiler/whatever takes care of resolving what type of file contents there is.
There are however some other considerations when deciding what to put into a .js
or a .jsx
file type. Since JSX isn't standard JavaScript one could argue that anything that is not "plain" JavaScript should go into its own extensions ie., .jsx
for JSX and .ts
for TypeScript for example.
There's a good discussion here available for read
I was having same issue, and the solution was working but with some alerts and warnings so here is full solution, the key was to check for existing DataTable object or not, if yes just clear the table and add jsonData, if not just create new.
var table;
if ($.fn.dataTable.isDataTable('#example')) {
table = $('#example').DataTable();
table.clear();
table.rows.add(jsonData).draw();
}
else {
table = $('#example').DataTable({
"data": jsonData,
"deferRender": true,
"pageLength": 25,
"retrieve": true,

Remove the newline/linefeed characters (\n
with Notepad++). Excel will still recognise the carriage return character (\r
) to separate records.
As mentioned newline characters are supported inside CSV fields but Excel doesn't always handle them gracefully. I faced a similar issue with a third party CSV that possibly had encoding issues but didn't improve with encoding changes.
What worked for me was removing all newline characters (\n
). This has the effect of collapsing fields to a single record assuming that your records are separated by the combination of a carriage return and a newline (CR/LF). Excel will then properly import the file and recognise new records by the carriage return.
Obviously a cleaner solution is to first replace the real newlines (\r\n
) with a temporary character combination, replacing the newlines (\n
) with your seperating character of choice (e.g. comma in a semicolon file) and then replacing the temporary characters with proper newlines again.
The usual method is to use the NEWID() function, which generates a unique GUID. So,
SELECT * FROM dbo.Foo ORDER BY NEWID();
This is possible using the mergeFunction
parameter of Collectors.toMap(keyMapper, valueMapper, mergeFunction)
:
Map<String, String> phoneBook =
people.stream()
.collect(Collectors.toMap(
Person::getName,
Person::getAddress,
(address1, address2) -> {
System.out.println("duplicate key found!");
return address1;
}
));
mergeFunction
is a function that operates on two values associated with the same key. adress1
corresponds to the first address that was encountered when collecting elements and adress2
corresponds to the second address encountered: this lambda just tells to keep the first address and ignores the second.
If you have this error trying to consume a service that you can't add the header Access-Control-Allow-Origin *
in that application, but you can put in front of the server a reverse proxy, the error can avoided with a header rewrite.
Assuming the application is running on the port 8080 (public domain at www.mydomain.com), and you put the reverse proxy in the same host at port 80, this is the configuration for Nginx reverse proxy:
server {
listen 80;
server_name www.mydomain.com;
access_log /var/log/nginx/www.mydomain.com.access.log;
error_log /var/log/nginx/www.mydomain.com.error.log;
location / {
proxy_pass http://127.0.0.1:8080;
add_header Access-Control-Allow-Origin *;
}
}
It seems there's some misunderstanding. So, instead of trying to patch VS2013 here's and answer from a Microsoft guy: https://social.msdn.microsoft.com/Forums/vstudio/en-US/49ba9a67-d26a-4b21-80ef-caeb081b878e/will-c-60-ever-be-supported-by-vs-2013?forum=roslyn
So, please, read it and install VS2015.
It will start as soon as the page loads. You can keep it under some events like button click
$("#btn").click(function() {
var val= $('input[type="radio"]:checked').val();
});
Service references deal with endpoints and bindings, which are completely configurable. They let you point your client proxy to a WCF via any transport protocol (HTTP, TCP, Shared Memory, etc)
They are designed to work with WCF.
If you use a WebProxy, you are pretty much binding yourself to using WCF over HTTP
You can check elasticsearch cluster health by using (CURL) and Cluster API provieded by elasticsearch:
$ curl -XGET 'localhost:9200/_cluster/health?pretty'
This will give you the status and other related data you need.
{
"cluster_name" : "xxxxxxxx",
"status" : "green",
"timed_out" : false,
"number_of_nodes" : 2,
"number_of_data_nodes" : 2,
"active_primary_shards" : 15,
"active_shards" : 12,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 0,
"delayed_unassigned_shards" : 0,
"number_of_pending_tasks" : 0,
"number_of_in_flight_fetch" : 0
}
The modulo operator is % (percent sign). To test for evenness or generally do modulo for a power of 2, you can also use & (the and operator) like isEven = !( a & 1 ).
Yes, you either need to do this onload
or in a <script>

Using Excel 2010 x64
. XY plot: I could not see no tabs (it is late and I am probably tired blind, 250 limit?). Here is what worked for me:
Swap the data columns, to end with X_data in column A and Y_data in column B.
My original data had Y_data in column A and X_data in column B, and the graph was rotated 90deg clockwise. I was suffering. Then it hit me:
an Excel XY plot literally wants {x,y}
pairs, i.e. X_data in first column and Y_data in second column. But it does not tell you this right away.
For me an XY plot means Y=f(X)
plotted.
I guess your end goal is to show Distinct (unique) values inside your original Pivot table.
For example you could have data set with OrderNumber, OrderDate, OrderItem, orderQty
First pivot table will show you OrderDate and sum of OrderQty and you probably want to see Count of unique orders in the same Pivot. You woudln't be able to do so within standard pivot table
If you want to do it, you would need Office 2016 (or perhaps pover Pivot might work). In office 2016 select your data > Insert > Pivot Table > choose tick "Add this data to the Data Model"
After that, you would be able to select grouping method as Distinct (Count)
I usually overload my method with IEnumerable and IList in this situation.
public static IEnumerable<T> Method<T>( this IList<T> source ){... }
public static IEnumerable<T> Method<T>( this IEnumerable<T> source )
{
/*input checks on source parameter here*/
return Method( source.ToList() );
}
I take care to explain in the summary comments of the methods that calling IEnumerable will perform a .ToList().
The programmer can choose to .ToList() at a higher level if multiple operations are being concatenated and then call the IList overload or let my IEnumerable overload take care of that.
Here is the slightly different C# version:
driver.Navigate().Refresh();
it simply means sorting the view or table by 1st column of query's result.
$(this).value
is attempting to call the 'value' property of a jQuery object, which does not exist. Native JavaScript does have a 'value' property on certain HTML objects, but if you are operating on a jQuery object you must access the value by calling $(this).val()
.
It will work in IE7. But here you need to fixed the size
less than the number of option
and not use overflow-y:scroll
. In your example you have 2 option
but you set size=10
, which will not work.
Suppose your select has 10 option
, then fixed size=9
.
Here, in your code reference you used height:100px
with size:2
. I remove the height
css, because its not necessary and change the size:5
and it works fine.
Here is your modified code from jsfiddle:
<select size="5" style="width:100px;">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
<option>6</option>
</select>
this will generate a larger select box than size:2
create.In case of small size
the select box will not display the scrollbar,you have to check with appropriate size
quantity.Without scrollbar it will work if click on the upper and lower icons of scrollbar.I show both example in your fiddle with size:2
and size
greater than 2
(e.g: 3,5).
Here is your desired result. I think this will help you:
CSS
.wrapper{
border: 1px dashed red;
height: 150px;
overflow-x: hidden;
overflow-y: scroll;
width: 150px;
}
.wrapper .selection{
width:150px;
border:1px solid #ccc
}
HTML
<div class="wrapper">
<select size="15" class="selection">
<option>Item 1</option>
<option>Item 2</option>
<option>Item 3</option>
</select>
</div>
"By default, when an application calls DriverManager.getConnection(url, ...)

Addendum: @Thomas Mueller shows how to Execute SQL on Connection, but I sometimes just create and populate in the code, as suggested below.

/** @see http://stackoverflow.com/questions/5225700 */

Statement st = conn.createStatement();
st.execute("create table customer(id integer, name varchar(10))");
st.execute("insert into customer values (1, 'Thomas')");

for this you need to just add css like this:
#video_overlays {
position: absolute;
background-color: rgba(0, 0, 0, 0.46);
z-index: 2;
left: 0;
right: 0;
top: 0;

}
#video_box{position: relative;}
My approach to delete all rows from a table i DynamoDb is just to pull all rows out from the table, using DynamoDbs ScanAsync and then feed the result list to DynamoDbs AddDeleteItems. Below code in C# works fine for me.
public async Task DeleteAllReadModelEntitiesInTable()
{
List<ReadModelEntity> readModels;
var conditions = new List<ScanCondition>();
readModels = await _context.ScanAsync<ReadModelEntity>(conditions).GetRemainingAsync();
var batchWork = _context.CreateBatchWrite<ReadModelEntity>();
batchWork.AddDeleteItems(readModels);
await batchWork.ExecuteAsync();
}
Note: Deleting the table and then recreating it again from the web console may cause problems if using YAML/CloudFormation to create the table.
For many new users don't forget to add an asterisk (*) after your import statements if you wanna use all the classes in a package....for example

// no error
}
}
================================================================

Possibly a more reliable way to get the up icon from your theme (if not using the toolbar as your action bar):
toolbar.navigationIcon = context.getDrawableFromAttribute(R.attr.homeAsUpIndicator)
In order to turn the theme attribute into a drawable I used an extension function:
fun Context.getDrawableFromAttribute(attributeId: Int): Drawable {
val typedValue = TypedValue().also { theme.resolveAttribute(attributeId, it, true) }
return resources.getDrawable(typedValue.resourceId, theme)
}
Here is a list of special characters that you can escape when creating a string literal for JSON:
\b Backspace (ASCII code 08) \f Form feed (ASCII code 0C) \n New line \r Carriage return \t Tab \v Vertical tab \' Apostrophe or single quote \" Double quote \\ Backslash character
Reference: String literals
Some of these are more optional than others. For instance, your string should be perfectly valid whether you escape the tab character or leave in a tab literal. You should certainly be handling the backslash and quote characters, though.
The best way I have found so far is to use React Context but to isolate it inside a high order provider component.
You will have to expand one of your upper views to fill the remaining space by setting android:layout_weight="1"
on it. This will push your last view down to the bottom.
Here is a brief sketch of what I mean:
<LinearLayout android:orientation="vertical">
<View/>
<View android:layout_weight="1"/>
<View/>
<View android:id="@+id/bottom"/>
</LinearLayout>
where each of the child view heights is "wrap_content"
and everything else is "fill_parent"
.
I found this the most simple when toggling boolean values. Simply put if the value is already true then it sets it to false and vice versa. Beware of undefined errors, make sure your property was defined before executing
this.setState({
propertyName: this.propertyName = !this.propertyName
});
Sometimes autoplay is needed. Someone once pointed out that the famous Les Paul Google Doodle (2011) required autoplay, even though the sound didn't play until you moused over the guitar strings. If it's done with class and great design it can be beautiful (especially movie websites with immersive design)
import java.util.*;
public class matrixcecil {
public static void main(String args[]){
List<Integer> k1=new ArrayList<Integer>(10);
k1.add(23);
k1.add(10);
k1.add(20);
k1.add(24);
int i=0;
while(k1.size()<10){
if(i==(k1.get(k1.size()-1))){
}
i=k1.get(k1.size()-1);
k1.add(30);
i++;
break;
}
System.out.println(k1);
}
}
I think this example will help you for better solution.
Internet Explorer 9 and lower : You could use conditional comments to load an IE-specific stylesheet for any version (or combination of versions) that you wanted to specifically target.like below using external stylesheet.
<!--[if IE]>
<link rel="stylesheet" type="text/css" href="all-ie-only.css" />
<![endif]-->
However, beginning in version 10, conditional comments are no longer supported in IE.
Internet Explorer 10 & 11 : Create a media query using -ms-high-contrast, in which you place your IE 10 and 11-specific CSS styles. Because -ms-high-contrast is Microsoft-specific (and only available in IE 10+), it will only be parsed in Internet Explorer 10 and greater.
@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
/* IE10+ CSS styles go here */
}
Microsoft Edge 12 : Can use the @supports rule Here is a link with all the info about this rule
@supports (-ms-accelerator:true) {
/* IE Edge 12+ CSS styles go here */
}
Inline rule IE8 detection
I have 1 more option but it is only detect IE8 and below version.
/* For IE css hack */
margin-top: 10px\9 /* apply to all ie from 8 and below */
*margin-top:10px; /* apply to ie 7 and below */
_margin-top:10px; /* apply to ie 6 and below */
As you specefied for embeded stylesheet. I think you need to use media query and condition comment for below version.
if (strpos($string, $word) === FALSE) {
... not found ...
}
Note that strpos()
is case sensitive, if you want a case-insensitive search, use stripos()
instead.
Also note the ===
, forcing a strict equality test. strpos CAN return a valid 0
if the 'needle' string is at the start of the 'haystack'. By forcing a check for an actual boolean false (aka 0), you eliminate that false positive.
They are related values, and kept consistent by the property setter/getter methods (and using the fact that frame is a purely synthesized value, not backed by an actual instance variable).
The main equations are:
frame.origin = center - bounds.size / 2
(which is the same as)
center = frame.origin + bounds.size / 2
(and there’s also)
frame.size = bounds.size
That's not code, just equations to express the invariant between the three properties. These equations also assume your view's transform is the identity, which it is by default. If it's not, then bounds and center keep the same meaning, but frame can change. Unless you're doing non-right-angle rotations, the frame will always be the transformed view in terms of the superview's coordinates.
This stuff is all explained in more detail with a useful mini-library here:
To handle the lazy loading with image existence check I followed this in jQuery-
$('[data-src]').each(function() {
var $image_place_holder_element = $(this);
var image_url = $(this).data('src');
$("<div class='hidden-classe' />").load(image_url, function(response, status, xhr) {
if (!(status == "error")) {
$image_place_holder_element.removeClass('image-placeholder');
$image_place_holder_element.attr('src', image_url);
}
}).remove();
});
Reason: if I am using $image_place_holder_element.load()
method it will be adding the response to the element, so random div and removing it appeared me a good solution. Hope it works for someone trying to implement lazy loading along with url check.
You can save it as follow if you have Pandas Dataframe
df.to_csv(r'/dir/filename.csv')
None of the other solutions worked for me, but this does:
Create your own subclass of UINavigationController, make it implement the UINavigationBarDelegate (no need to manually set the navigation bar's delegate), add a UIViewController extension that defines a method to be called on a back button press, and then implement this method in your UINavigationController subclass:
func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool {
self.topViewController?.methodToBeCalledOnBackButtonPress()
self.popViewController(animated: true)
return true
}

Sorry to drag this up after so long but I used the below. Any disadvantages? See the open function...
$("#popup").dialog(
{
height: 670,
width: 680,
modal: true,
autoOpen: false,
close: function(event, ui) { $('#wrap').show(); },
open: function(event, ui)
{
$('.ui-widget-overlay').bind('click', function()
{
$("#popup").dialog('close');
});
}
});
$( this ).find( 'li.target' ).css("border", "3px double red");
or
$( this ).children( 'li.target' ).css("border", "3px double red");
Use children
for immediate descendants, or find
for deeper elements.
NULL values are stored separately in a special bitmap space for all the columns.
If you do not distinguish between NULL
and ''
in your application, then I would recommend you to store ''
in your tables (unless the string column is a foreign key, in which case it would probably be better to prohibit the column from storing empty strings and allow the NULLs, if that is compatible with the logic of your application).
I was having trouble with Dan's proposed solution, but this worked for me:
import json
import csv
f = open('test.json')
data = json.load(f)
f.close()
f=csv.writer(open('test.csv','wb+'))
for item in data:
f.writerow([item['pk'], item['model']] + item['fields'].values())
Where "test.json" contained the following:
[
{"pk": 22, "model": "auth.permission", "fields":
{"codename": "add_logentry", "name": "Can add log entry", "content_type": 8 } },
{"pk": 23, "model": "auth.permission", "fields":
{"codename": "change_logentry", "name": "Can change log entry", "content_type": 8 } }, {"pk": 24, "model": "auth.permission", "fields":
{"codename": "delete_logentry", "name": "Can delete log entry", "content_type": 8 } }
]
Like others already wrote, in short:
shared project
reuse on the code (file) level, allowing for folder structure and resources as well
pcl
reuse on the assembly level
What was mostly missing from answers here for me is the info on reduced functionality available in a PCL: as an example you have limited file operations (I was missing a lot of File.IO fuctionality in a Xamarin cross-platform project).
In more detail
shared project:
+ Can use #if when targeting multiple platforms (e. g. Xamarin iOS, Android, WinPhone)
+ All framework functionality available for each target project (though has to be conditionally compiled)
o Integrates at compile time
- Slightly larger size of resulting assemblies
- Needs Visual Studio 2013 Update 2 or higher
pcl:
+ generates a shared assembly
+ usable with older versions of Visual Studio (pre-2013 Update 2)
o dynamically linked
- lmited functionality (subset of all projects it is being referenced by)
If you have the choice, I would recommend going for shared project, it is generally more flexible and more powerful. If you know your requirements in advance and a PCL can fulfill them, you might go that route as well. PCL also enforces clearer separation by not allowing you to write platform-specific code (which might not be a good choice to be put into a shared assembly in the first place).
Main focus of both is when you target multiple platforms, else you would normally use just an ordinary library/dll project.
cout.fill( '0' );
cout.width( 3 );

Just setting json
option to true
, the body will contain the parsed json:
request({
url: 'http://...',
json: true
}, function(error, response, body) {
console.log(body);
});
Firstly, you shouldn't have multiple elements with the same ID on a page - ID should be unique.
You could just remove the id attribute and and replace it with:
<input type='text' name='task'>
and to get an array of the values of task do
var taskArray = new Array();
$("input[name=task]").each(function() {
taskArray.push($(this).val());
});
