Here's a slide in/out animation between fragments:
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.setCustomAnimations(R.animator.enter_anim, R.animator.exit_anim);
transaction.replace(R.id.listFragment, new YourFragment());
transaction.commit();
We are using an objectAnimator.
Here are the two xml files in the animator subfolder.
enter_anim.xml
<?xml version="1.0" encoding="utf-8"?>
<set>
<objectAnimator
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:propertyName="x"
android:valueFrom="2000"
android:valueTo="0"
android:valueType="floatType" />
</set>
exit_anim.xml
<?xml version="1.0" encoding="utf-8"?>
<set>
<objectAnimator
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:propertyName="x"

android:valueType="floatType" />
</set>
I hope that would help someone.
I try to have two pings in the same window, and it is a serial command on the same line. After finishing the first, run the second command.
The solution was to combine with start /b
on a Windows 7 command prompt.
Start as usual, without /b
, and launch in a separate window.
The command used to launch in the same line is:
start /b command1 parameters & command2 parameters
Any way, if you wish to parse the output, I don't recommend to use this. I noticed the output is scrambled between the output of the commands.
.NET supports value types
and reference types
(in Java, you can define only reference types). Instances of reference types
get allocated in the managed heap and are garbage collected when there are no outstanding references to them. Instances of value types
, on the other hand, are allocated in the stack
, and hence allocated memory is reclaimed as soon as their scope ends. And of course, value types
get passed by value, and reference types
by reference. All C# primitive data types, except for System.String, are value types.
When to use struct over class,
In C#, structs
are value types
, classes are reference types
. You can create value types, in C#, using the enum
keyword and the struct
keyword. Using a value type
instead of a reference type
will result in fewer objects on the managed heap, which results in lesser load on the garbage collector (GC), less frequent GC cycles, and consequently better performance. However, value types
have their downsides too. Passing around a big struct
is definitely costlier than passing a reference, that's one obvious problem. The other problem is the overhead associated with boxing/unboxing
. In case you're wondering what boxing/unboxing
mean, follow these links for a good explanation on boxing
and unboxing
. Apart from performance, there are times when you simply need types to have value semantics, which would be very difficult (or ugly) to implement if reference types
are all you have. You should use value types
only, When you need copy semantics or need automatic initialization, normally in arrays
of these types.
The multi-column index can be used for queries referencing all the columns:
SELECT *
FROM TableName
WHERE Column1=1 AND Column2=2 AND Column3=3
This can be looked up directly using the multi-column index. On the other hand, at most one of the single-column index can be used (it would have to look up all records having Column1=1, and then check Column2 and Column3 in each of those).
Here is an example I think that will help you

Add a reference to the Outlook object model in the Visual Basic editor. Then you can use the code below to send an email using outlook.
Sub sendOutlookEmail()
Dim oApp As Outlook.Application
Dim oMail As MailItem
Set oApp = CreateObject("Outlook.application")
Set oMail = oApp.CreateItem(olMailItem)
oMail.Body = "Body of the email"
oMail.Subject = "Test Subject"
oMail.To = "[email protected]"
oMail.Send
Set oMail = Nothing
Set oApp = Nothing

When a user logs in on my website, a User() object is instantiated from the username and password.
If I need a user object without the user being there to log in (e.g. an admin user might want to delete another users account, so i need to instantiate that user and call its delete method):
I have class methods to grab the user object.
class User():
#lots of code
#...
# more code
@classmethod
def get_by_username(cls, username):
return cls.query(cls.username == username).get()
@classmethod
def get_by_auth_id(cls, auth_id):
return cls.query(cls.auth_id == auth_id).get()
$('.IsBestAnswer').removeClass('IsBestAnswer').addClass('bestanswer');
Your code has two problems:
.IsBestAnswe
does not match what you thoughtaddClass()
, not addclass()
.Also, I'm not sure whether you want to replace the class or add it. The above will replace, but remove the .removeClass('IsBestAnswer')
part to add only:
$('.IsBestAnswer').addClass('bestanswer');
You should decide whether to use camelCase or all-lowercase in your CSS classes too (e.g. bestAnswer
vs. bestanswer
).
I would recommend using DialogFragment
.
Sure, creating a "Yes/No" dialog with it is pretty complex considering that it should be rather simple task, but creating a similar dialog box with Dialog
is surprisingly complicated as well.
(Activity lifecycle makes it complicated - you must let Activity
manage the lifecycle of the dialog box - and there is no way to pass custom parameters e.g. the custom message to Activity.showDialog
if using API levels under 8)
The nice thing is that you can usually build your own abstraction on top of DialogFragment
pretty easily.
Add a class to your CSS that defines you cannot select or highlight an element. I have an example:
<style>
.no_highlighting{
user-select: none;
}
.anchor_without_decoration:hover{
text-decoration-style: none;
}
</style>
<a href="#" class="anchor_without_decoration no_highlighting">Anchor text</a>
You need to initialize the list first:
protected List<string> list = new List<string>();
One way you could do it is have a file with the username and pass directly under it. Then uses the Scanner class and when you create it, make the file the parameter for the Scanner. Then use the methods hasNext(); and nextLine to verify the username and password;
String user;
String pass;
Scanner scan = new Scanner(new File("File.txt"));
while(scan.hasNext){ //While the file still has more lines remaining
if(scan.nextLine() == user){
if(scan.nextLine == pass){
lblDisplay.setText("Credentials Accepted.");
}
else{
lblDisplay.setText("Please try again.");
}
}
}
If you write on Kotlin, you can use:
val firstProcess = ProcessBuilder("echo","hello world").start()
val firstError = firstProcess.errorStream.readBytes().decodeToString()
val firstResult = firstProcess.inputStream.readBytes().decodeToString()
Use HH
for 24 hour hours format:
DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")
Or the tt
format specifier for the AM/PM
part:
DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss tt")
Take a look at the custom Date and Time format strings documentation.
For repeating an action in the future, there is the built in setInterval
function that you can use instead of setTimeout
.
It has a similar signature, so the transition from one to another is simple:
setInterval(function() {
// do stuff
}, duration);
This will do exactly what you done in php:
var a = 1;
var b = 2;
var ccc = 3;
var name = 'a';
console.log( window[name] ); // 1
Maybe you can try this:
void foo(const char* str)
{
// Do something
}
foo("Hello")
It works for me
With the constructor:
// create a vector with 20 integer elements
std::vector<int> arr(20);
for(int x = 0; x < 20; ++x)
arr[x] = x;
If you are working on .NET 4.5 project in VS 2012 (or newer), you can just Special Paste your XML file as classes.
EDIT > Paste Special > Paste XML As Classes
You can still use EditorFor. Just pass the style/whichever html attribute as ViewData.
@Html.EditorFor(model => model.YourProperty, new { style = "Width:50px" })
Because EditorFor uses templates to render, you could override the default template for your property and simply pass the style attribute as ViewData.
So your EditorTemplate would like the following:
@inherits System.Web.Mvc.WebViewPage<object>
@Html.TextBoxFor(m => m, new { @class = "text ui-widget-content", style=ViewData["style"] })
So, first of all, your Javascript isn't even using jQuery. There are a couple ways to do this. For example:
First way, using the jQuery toggle
method:
<div class="expandContent">
<a href="#">Click Here to Display More Content</a>
</div>
<div class="showMe" style="display:none">
This content was hidden, but now shows up
</div>
<script>
$('.expandContent').click(function(){
$('.showMe').toggle();
});
</script>
jsFiddle: http://jsfiddle.net/pM3DF/
Another way is simply to use the jQuery show
method:
<div class="expandContent">
<a href="#">Click Here to Display More Content</a>
</div>
<div class="showMe" style="display:none">
This content was hidden, but now shows up
</div>
<script>
$('.expandContent').click(function(){
$('.showMe').show();
});
</script>
jsFiddle: http://jsfiddle.net/Q2wfM/
Yet a third way is to use the slideToggle
method of jQuery which allows for some effects. Such as $('#showMe').slideToggle('slow');
which will slowly display the hidden div.
Here's your bulletproof solution:
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="33%" align="center" valign="top" style="font-family:Arial, Helvetica, sans-serif; font-size:2px; color:#ffffff;">.</td>
<td width="35%" align="center" valign="top">
CONTENT GOES HERE
</td>
<td width="33%" align="center" valign="top" style="font-family:Arial, Helvetica, sans-serif; font-size:2px; color:#ffffff;">.</td>
</tr>
</table>
Just Try it out, Looks a bit messy, but It works Even with the new Firefox Update for Yahoo mail. (doesn't center the email because replace the main table by a div)
With pure JavaScript you can do this (such as SQL) and anything you need, basically:

So I changed it so that now it executes after a 300 miliseconds using setTimeout. Seems to be working now.
I have run into this many times when loading data from an Ajax call. I too use .NET, and it takes time to get adjusted to the clientId when using the jQuery selector. To correct the problem that you're having and to avoid having to add a setTimeout
property, you can simply put "async: false
" in the Ajax call, and it will give the DOM enough time to have the objects back that you are adding to the select. A small sample below:
$.ajax({
type: "POST",
url: document.URL + '/PageList',
data: "{}",
async: false,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
var pages = (typeof response.d) == 'string' ? eval('(' + response.d + ')') : response.d;
$('#locPage' + locId).find('option').remove();
$.each(pages, function () {
$('#locPage' + locId).append(
$('<option></option>').val(this.PageId).html(this.Name)
);
});
}
});
You are trying to call DeckOfCards::shuffle
with a deckOfCards
parameter:
deckOfCards cardDeck; // create DeckOfCards object
cardDeck.shuffle(cardDeck); // shuffle the cards in the deck
But the method takes a vector<Card>&
:
void deckOfCards::shuffle(vector<Card>& deck)
The compiler error messages are quite clear on this. I'll paraphrase the compiler as it talks to you.
Error:
[Error] no matching function for call to 'deckOfCards::shuffle(deckOfCards&)'
Paraphrased:
Hey, pal. You're trying to call a function called
shuffle
which apparently takes a single parameter of type reference-to-deckOfCards
, but there is no such function.
Error:
[Note] candidate is:
In file included from main.cpp
[Note] void deckOfCards::shuffle(std::vector&)
Paraphrased:
I mean, maybe you meant this other function called
shuffle
, but that one takes a reference-tovector<something>
.
Error:
[Note] no known conversion for argument 1 from 'deckOfCards' to 'std::vector&'
Which I'd be happy to call if I knew how to convert from a
deckOfCards
to avector
; but I don't. So I won't.
The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function.
Use
Z=XY[0]+XY[1]
Instead of
Z=XY(i,0)+XY(i,1)
I had the problem that time picker buttons have not been seen in the screen for API 24 in android. (API 21+) it is solved by
<style name="MyDatePickerDialogTheme" parent="android:Theme.Material.Light.Dialog">
<item name="android:colorAccent">@color/colorPrimary2</item></style>
<style name="Theme" parent="BBaseTheme">
<item name="android:datePickerDialogTheme">@style/MyDatePickerDialogTheme</item>
</style>
I used the following on Mac OSX.
currDate=`date +%Y%m%d`
epochDate=$(date -j -f "%Y%m%d" "${currDate}" "+%s")
In my case, I wanted a Tab delimited row.
from pyspark.sql import functions as F
df.select(F.concat_ws('|','_c1','_c2','_c3','_c4')).show()
This worked well like a hot knife over butter.
On PC it's by default set to Ctrl + /. This will toggle commenting a selection or current line.

Assuming that the program cannot be redesigned to avoid the cast (ref. Keith Thomson's answer):
To cast from size_t to int you need to ensure that the size_t does not exceed the maximum value of the int. This can be done using std::numeric_limits:
int SizeTToInt(size_t data)
{
if (data > std::numeric_limits<int>::max())
throw std::exception("Invalid cast.");
return std::static_cast<int>(data);
}
If you need to cast from size_t to double, and you need to ensure that you don't lose precision, I think you can use a narrow cast (ref. Stroustrup: The C++ Programming Language, Fourth Edition):
template<class Target, class Source>
Target NarrowCast(Source v)
{
auto r = static_cast<Target>(v);
if (static_cast<Source>(r) != v)
throw RuntimeError("Narrow cast failed.");
return r;
}
I tested using the narrow cast for size_t-to-double conversions by inspecting the limits of the maximum integers floating-point-representable integers (code uses googletest):
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() - 2 })), size_t{ IntegerRepresentableBoundary() - 2 });
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() - 1 })), size_t{ IntegerRepresentableBoundary() - 1 });
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() })), size_t{ IntegerRepresentableBoundary() });
EXPECT_THROW(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 1 }), std::exception);
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 2 })), size_t{ IntegerRepresentableBoundary() + 2 });
EXPECT_THROW(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 3 }), std::exception);
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 4 })), size_t{ IntegerRepresentableBoundary() + 4 });
EXPECT_THROW(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 5 }), std::exception);
where
constexpr size_t IntegerRepresentableBoundary()
{
static_assert(std::numeric_limits<double>::radix == 2, "Method only valid for binary floating point format.");
return size_t{2} << (std::numeric_limits<double>::digits - 1);
}
That is, if N is the number of digits in the mantissa, for doubles smaller than or equal to 2^N, integers can be exactly represented. For doubles between 2^N and 2^(N+1), every other integer can be exactly represented. For doubles between 2^(N+1) and 2^(N+2) every fourth integer can be exactly represented, and so on.

If you have the flag -ObjC
under your Target > Build Settings > Other Linker Flags and you're getting this issue, consider removing it. If you intentionally added it because you need to load some Obj-C code from a static library that wouldn't normally be loaded otherwise, IE, an Obj-C category, then you should use -force_load <path>
instead of -ObjC
.
<path>
should be relative to your Xcode project directory. IE, if your directory structure looks like this:
iOSProject
+ iOSAPI.framework
+ iOSAPI
+ iOSAPI.xcodeproj
Then you should have this flag set for Other Linker Flags
:
-force_load iOSAPI.framework/iOSAPI
If you want to include multiple libraries like that, then you should include a separate -force_load
line for each of them.
-force_load iOSAPI.framework/iOSAPI
-force_load another.framework/another
I have Visual Studio 2013 Express. I had to delete the registry key under:
hkey_current_user\software\Microsoft\VSCommon\12.\clientservices\tokenstorge\VWDExpress\ideuser
I prefer to use:
string result = "myFile_" + DateTime.Now.ToFileTime() + ".txt";
What does ToFileTime() do?
Converts the value of the current DateTime object to a Windows file time.
public long ToFileTime()
A Windows file time is a 64-bit value that represents the number of 100-nanosecond intervals that have elapsed since 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC). Windows uses a file time to record when an application creates, accesses, or writes to a file.
Try to save the .config file as utf-8 if you have some "special" characters in there. That was the issue in my case of a console application.
Use usort()
and a custom comparison function:
function date_compare($a, $b)
{
$t1 = strtotime($a['datetime']);
$t2 = strtotime($b['datetime']);
return $t1 - $t2;
}
usort($array, 'date_compare');
EDIT: Your data is organized in an array of arrays. To better distinguish those, let's call the inner arrays (data) records, so that your data really is an array of records.
usort
will pass two of these records to the given comparison function date_compare()
at a a time. date_compare
then extracts the "datetime"
field of each record as a UNIX timestamp (an integer), and returns the difference, so that the result will be 0
if both dates are equal, a positive number if the first one ($a
) is larger or a negative value if the second argument ($b
) is larger. usort()
uses this information to sort the array.
Either of the latter two, since val
could potentially be of a type that defines __eq__()
to return true when passed None
.
Just as Oded has answered. You need to have this sort of detection functionality in javascript.
I've struggled with this myself and realized that the offset is not enough. It does not give you any information about daylight saving for example. I ended up writing some code to map to zoneinfo database keys.
By checking several dates around a year you can more accurately determine a timezone.
Try the script here: http://jsfiddle.net/pellepim/CsNcf/
Simply change your system timezone and click run to test it. If you are running chrome you need to do each test in a new tab though (and safar needs to be restarted to pick up timezone changes).
If you want more details of the code check out: https://bitbucket.org/pellepim/jstimezonedetect/
Since you haven't made any commits yet, you can save all your changes to the stash, create and switch to a new branch, then pop those changes back into your working tree:
git stash # save local modifications to new stash
git checkout -b topic/newbranch
git stash pop # apply stash and remove it from the stash list

Just call fig.tight_layout()
as you normally would. (pyplot
is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)
There shouldn't be a difference between the QtAgg
backend and the default backend (or if there is, it's a bug).
E.g.
import matplotlib.pyplot as plt
#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so
#-- we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)
for i, ax in enumerate(axes.flat, start=1):
ax.set_title('Test Axes {}'.format(i))
ax.set_xlabel('X axis')
ax.set_ylabel('Y axis')
plt.show()
import matplotlib.pyplot as plt
fig, axes = plt.subplots(nrows=4, ncols=4)
for i, ax in enumerate(axes.flat, start=1):
ax.set_title('Test Axes {}'.format(i))
ax.set_xlabel('X axis')
ax.set_ylabel('Y axis')
fig.tight_layout()
plt.show()

d=["{} hours {} mins {} seconds".format(a, b, c)]

print(sec_to_hours(10000))

It's not creating a file because you never actually created the file. You made an object for it. Creating an instance doesn't create the file.
File newFile = new File("directory", "fileName.txt");
You can do this to make a file:
newFile.createNewFile();
You can do this to make a folder:
newFile.mkdir();
In a terminal put these:
cd C:\Program Files (x86)\Google\Chrome\Application
chrome.exe --disable-web-security --user-data-dir="c:/chromedev"
In C++11 you have two new options, as the Variadic functions reference page in the Alternatives section states:
- Variadic templates can also be used to create functions that take variable number of arguments. They are often the better choice because they do not impose restrictions on the types of the arguments, do not perform integral and floating-point promotions, and are type safe. (since C++11)
- If all variable arguments share a common type, a std::initializer_list provides a convenient mechanism (albeit with a different syntax) for accessing variable arguments.
Below is an example showing both alternatives (see it live):
#include <iostream>
#include <string>
#include <initializer_list>
template <typename T>
void func(T t)
{
std::cout << t << std::endl ;
}
template<typename T, typename... Args>
void func(T t, Args... args) // recursive variadic function
{
std::cout << t <<std::endl ;
func(args...) ;
}
template <class T>
void func2( std::initializer_list<T> list )
{
for( auto elem : list )
{
std::cout << elem << std::endl ;
}
}
int main()
{
std::string
str1( "Hello" ),
str2( "world" );
func(1,2.5,'a',str1);
func2( {10, 20, 30, 40 }) ;
func2( {str1, str2 } ) ;
}
If you are using gcc
or clang
we can use the PRETTY_FUNCTION magic variable to display the type signature of the function which can be helpful in understanding what is going on. For example using:
std::cout << __PRETTY_FUNCTION__ << ": " << t <<std::endl ;
would results int following for variadic functions in the example (see it live):
void func(T, Args...) [T = int, Args = <double, char, std::basic_string<char>>]: 1
void func(T, Args...) [T = double, Args = <char, std::basic_string<char>>]: 2.5
void func(T, Args...) [T = char, Args = <std::basic_string<char>>]: a
void func(T) [T = std::basic_string<char>]: Hello
In Visual Studio you can use FUNCSIG.
Update Pre C++11
Pre C++11 the alternative for std::initializer_list would be std::vector or one of the other standard containers:
#include <iostream>
#include <string>
#include <vector>
template <class T>
void func1( std::vector<T> vec )
{
for( typename std::vector<T>::iterator iter = vec.begin(); iter != vec.end(); ++iter )
{
std::cout << *iter << std::endl ;
}
}
int main()
{
int arr1[] = {10, 20, 30, 40} ;
std::string arr2[] = { "hello", "world" } ;
std::vector<int> v1( arr1, arr1+4 ) ;
std::vector<std::string> v2( arr2, arr2+2 ) ;
func1( v1 ) ;
func1( v2 ) ;
}
and the alternative for variadic templates would be variadic functions although they are not type-safe and in general error prone and can be unsafe to use but the only other potential alternative would be to use default arguments, although that has limited use. The example below is a modified version of the sample code in the linked reference:
#include <iostream>
#include <string>
#include <cstdarg>
void simple_printf(const char *fmt, ...)
{
va_list args;
va_start(args, fmt);
while (*fmt != '\0') {
if (*fmt == 'd') {
int i = va_arg(args, int);
std::cout << i << '\n';
} else if (*fmt == 's') {
char * s = va_arg(args, char*);
std::cout << s << '\n';
}
++fmt;
}
va_end(args);
}
int main()
{
std::string
str1( "Hello" ),
str2( "world" );
simple_printf("dddd", 10, 20, 30, 40 );
simple_printf("ss", str1.c_str(), str2.c_str() );
return 0 ;
}
Using variadic functions also comes with restrictions in the arguments you can pass which is detailed in the draft C++ standard in section 5.2.2
Function call paragraph 7:
When there is no parameter for a given argument, the argument is passed in such a way that the receiving function can obtain the value of the argument by invoking va_arg (18.7). The lvalue-to-rvalue (4.1), array-to-pointer (4.2), and function-to-pointer (4.3) standard conversions are performed on the argument expression. After these conversions, if the argument does not have arithmetic, enumeration, pointer, pointer to member, or class type, the program is ill-formed. If the argument has a non-POD class type (clause 9), the behavior is undefined. [...]
If you invoke the shell with script-file, db address, and --quiet arguments, you can redirect the output (made with print() for example) to a file:
mongo localhost/mydatabase --quiet myScriptFile.js > output
While you do the following, technically speaking:
<button ng-click="doSomething($event)"></button>
// In controller:
$scope.doSomething = function($event) {
//reference to the button that triggered the function:
$event.target
};
This is probably something you don't want to do as AngularJS philosophy is to focus on model manipulation and let AngularJS do the rendering (based on hints from the declarative UI). Manipulating DOM elements and attributes from a controller is a big no-no in AngularJS world.

Character varying is different than text. Try running
ALTER TABLE product_product ALTER COLUMN code TYPE text;
That will change the column type to text, which is limited to some very large amount of data (you would probably never actually hit it.)
There's a rather crude way of doing this, but be careful because first, this relies on python interpreter process identifying themselves as python, and second, it has the concomitant effect of also killing any other processes identified by that name.
In short, you can kill all python interpreters by typing this into your shell (make sure you read the caveats above!):
ps aux | grep python | grep -v "grep python" | awk '{print $2}' | xargs kill -9
To break this down, this is how it works. The first bit, ps aux | grep python | grep -v "grep python"
, gets the list of all processes calling themselves python, with the grep -v making sure that the grep command you just ran isn't also included in the output. Next, we use awk to get the second column of the output, which has the process ID's. Finally, these processes are all (rather unceremoniously) killed by supplying each of them with kill -9
.
In terminal : rvm gemset use global
In Short
android:id="@+id/my_button"
+id Plus sign tells android to add or create a new id in Resources.
while
android:layout_below="@id/my_button"
it just help to refer the already generated id..
My current solution uses the async module to execute in series:
var fs = require('fs');
var parse = require('csv-parse');
var async = require('async');
var inputFile='myfile.csv';
var parser = parse({delimiter: ','}, function (err, data) {
async.eachSeries(data, function (line, callback) {
// do something with the line
doSomething(line).then(function() {
// when processing finishes invoke the callback to move to the next one
callback();
});
})
});
fs.createReadStream(inputFile).pipe(parser);
An easier alternative for those who would prefer not to write all that configuration boilerplate manually...
1) Install Nerdle.AutoConfig from NuGet
2) Define your ServiceConfig type (either a concrete class or just an interface, either will do)
public interface IServiceConfiguration
{
int Port { get; }
ReportType ReportType { get; }
}
3) You'll need a type to hold the collection, e.g.
public interface IServiceCollectionConfiguration
{
IEnumerable<IServiceConfiguration> Services { get; }
}
4) Add the config section like so (note camelCase naming)
<configSections>
<section name="serviceCollection" type="Nerdle.AutoConfig.Section, Nerdle.AutoConfig"/>
</configSections>
<serviceCollection>
<services>
<service port="6996" reportType="File" />
<service port="7001" reportType="Other" />
</services>
</serviceCollection>
5) Map with AutoConfig
var services = AutoConfig.Map<IServiceCollectionConfiguration>();

The resolution of DateTime.Now
depends on your system timer (~10ms on a current Windows OS)...so it's giving the same ending value there (it doesn't count any more finite than that).
This has always worked for me.
Provided you set a fixed width for your DIV, and the proper DOCTYPE, try this
div {
margin-left:auto;
margin-right:auto;
}

"#if one" means that if "#define one" has been written "#if one" is executed otherwise "#ifndef one" is executed.
This is just the C Pre-Processor (CPP) Directive equivalent of the if, then, else branch statements in the C language.
i.e. if {#define one} then printf("one evaluates to a truth "); else printf("one is not defined "); so if there was no #define one statement then the else branch of the statement would be executed.
I was able to write a general contains
function for std::list
and std::vector
,
template<typename T>
bool contains( const list<T>& container, const T& elt )
{
return find( container.begin(), container.end(), elt ) != container.end() ;
}
template<typename T>
bool contains( const vector<T>& container, const T& elt )
{
return find( container.begin(), container.end(), elt ) != container.end() ;
}
// use:
if( contains( yourList, itemInList ) ) // then do something
This cleans up the syntax a bit.
But I could not use template template parameter magic to make this work arbitrary stl containers.
// NOT WORKING:
template<template<class> class STLContainer, class T>
bool contains( STLContainer<T> container, T elt )
{
return find( container.begin(), container.end(), elt ) != container.end() ;
}
Any comments about improving the last answer would be nice.

the right way(!) to do it is to
fork forks, setsid tell the current process to become a master one (no parent), execve tell the calling process to be replaced by the called one. so that the parent can quit without affecting the child.
$pid=pcntl_fork();
if($pid==0)
{
posix_setsid();
pcntl_exec($cmd,$args,$_ENV);
// child becomes the standalone detached process
}
// parent's stuff
exit();
There's a property in CSS called box-sizing.
It determines the total width of an element on your page. The default value is content-box
, which doesn't include the padding, margin, or border of the element.
Hence, if you set a div
to have width: 500px
and 20px
padding all around, it will take up 540px
on your website (500 + 20 + 20).
This is what is causing your problem. Bootstrap calculates set widths for things just like the above example, and these things don't have borders. Since Bootstrap fits together like a puzzle, adding a border to one of the sides would yield a total width of 501px (continuing the above example) and break your layout.
The easiest way to fix this is to adjust your box-sizing
. The value you would use is box-sizing: border-box
. This includes the padding and border in your box elements. You can read more about box-sizing here.
A problem with this solution is that it only works on IE8+. Consequently, if you need deeper IE support you'll need to override the Bootstrap widths to account for your border.
To give an example of how to calculate a new width, begin by checking the width that Bootstrap sets on your element. Let's say it's a span6
and has a width of 320px
(this is purely hypothetical, the actual width of your span6 will depend on your specific configuration of Bootstrap). If you wanted to add a single border on the right hand side with a 20px padding over there, you'd write this CSS in your stylesheet
.span6 {
padding-right: 20px;
border-right: 1px solid #ddd;
width: 299px;
}
where the new width is calculated by:
old width - padding - border
You could try a for loop
for func,args,kwargs in zip([a,b,c,d],
[args_a,args_b,args_c,args_d],
[kw_a,kw_b,kw_c,kw_d]):
try:
func(*args, **kwargs)
break
except:
pass
This way you can loop as many functions as you want without making the code look ugly
You should first pull
the changes from the develop
branch and only then merge them to your branch:
git checkout develop
git pull
git checkout branch-x
git rebase develop
Or, when on branch-x
:
git fetch && git rebase origin/develop
I have an alias that saves me a lot of time. Add to your ~/.gitconfig
:
[alias]
fr = "!f() { git fetch && git rebase origin/"$1"; }; f"
Now, all that you have to do is:
git fr develop
You're pretty much right about cout
and cin
. They are objects (not functions) defined inside the std
namespace. Here are their declarations as defined by the C++ standard:
Header
<iostream>
synopsis#include <ios> #include <streambuf> #include <istream> #include <ostream> namespace std { extern istream cin; extern ostream cout; extern ostream cerr; extern ostream clog; extern wistream wcin; extern wostream wcout; extern wostream wcerr; extern wostream wclog; }
::
is known as the scope resolution operator. The names cout
and cin
are defined within std
, so we have to qualify their names with std::
.
Classes behave a little like namespaces in that the names declared inside the class belong to the class. For example:
class foo
{
public:
foo();
void bar();
};
The constructor named foo
is a member of the class named foo
. They have the same name because its the constructor. The function bar
is also a member of foo
.
Because they are members of foo
, when referring to them from outside the class, we have to qualify their names. After all, they belong to that class. So if you're going to define the constructor and bar
outside the class, you need to do it like so:
foo::foo()
{
// Implement the constructor
}
void foo::bar()
{
// Implement bar
}
This is because they are being defined outside the class. If you had not put the foo::
qualification on the names, you would be defining some new functions in the global scope, rather than as members of foo
. For example, this is entirely different bar
:
void bar()
{
// Implement different bar
}
It's allowed to have the same name as the function in the foo
class because it's in a different scope. This bar
is in the global scope, whereas the other bar
belonged to the foo
class.

Threads -- > Threads shares a memory space,it is an abstraction of the CPU,it is lightweight. Processes --> Processes have their own memory space,it is an abstraction of a computer. To parallelise task you need to abstract a CPU. However the advantages of using a process over a thread is security,stability while a thread uses lesser memory than process and offers lesser latency. An example in terms of web would be chrome and firefox. In case of Chrome each tab is a new process hence memory usage of chrome is higher than firefox ,while the security and stability provided is better than firefox. The security here provided by chrome is better,since each tab is a new process different tab cannot snoop into the memory space of a given process.
Wow, what a variety of causes of these error messages! I'll throw one more out:
In my case, Eclipse 4.17 on Ubuntu 16.04LTS was showing these messages for multiple operations. It turns out that 16.04LTS has GTK 3.18, but Eclipse 4.17 requires GTK 3.20. Updating GTK (https://askubuntu.com/questions/933010/how-to-upgrade-gtk-3-18-to-3-20-on-ubuntu-16-04) made the error messages go away.
Hope this will help some how in your case, I suffered with the exact same problem, and just used localstorage to share the data between parent window and iframe. So in parent window you can:
localStorage.setItem("url", myUrl);
And in code where iframe source is just get this data from localstorage:
localStorage.getItem('url');
Saved me a lot of time. As far as i can see the only condition is access to the parent page code. Hope this will help someone.
Along the same lines as previous answers, but a very short addition that Allows to use all Control properties without having cross thread invokation exception.

Only suggestion is to access your resp_dict
via .get()
for a more graceful approach that will degrade well if the data isn't as expected.
resp_dict = json.loads(resp_str)
resp_dict.get('name') # will return None if 'name' doesn't exist
You could also add some logic to test for the key if you want as well.
if 'name' in resp_dict:
resp_dict['name']
else:
# do something else here.
I believe you've encountered the catch 22 of tables. Tables are great for wrapping up content in a tabular structure and they do a wonderful job of "stretching" to meet the needs of the content they contain.
By default the table cells will stretch to fit content... thus your text just makes it wider.
There's a few solutions.
1.) You can try setting a max-width on the TD.
<td style="max-width:150px;">
2.) You can try putting your text in a wrapping element (e.g. a span) and set constraints on it.
<td><span style="max-width:150px;">Hello World...</span></td>
Be aware though that older versions of IE don't support min/max-width.
Since IE doesn't support max-width natively you'll need to add a hack if you want to force it to. There's several ways to add a hack, this is just one.
On page load, for IE6 only, get the rendered width of the table (in pixels) then get 15% of that and apply that as the width to the first TD in that column (or TH if you have headers) again, in pixels.
Apache/HTTPD tends to be around in most enterprises or if you're using Centos/etc at home. So, if you have that around, you can do a proxy very easily to add the necessary CORS headers.
I have a blog post on this here as I suffered with it quite a few times recently. But the important bit is just adding this to your /etc/httpd/conf/httpd.conf file and ensuring you are already doing "Listen 80":
<VirtualHost *:80>
<LocationMatch "/SomePath">
ProxyPass http://target-ip:8080/SomePath
Header add "Access-Control-Allow-Origin" "*"
</LocationMatch>
</VirtualHost>
This ensures that all requests to URLs under your-server-ip:80/SomePath route to http://target-ip:8080/SomePath (the API without CORS support) and that they return with the correct Access-Control-Allow-Origin header to allow them to work with your web-app.
Of course you can change the ports and target the whole server rather than SomePath if you like.
Sure, find where -Werror
is set and remove that flag. Then warnings will be only warnings.

If you want the user to be able to manually enter data into a table:
Console.Write("Enter Data For Column 1: ")
Dim Data1 As String = Console.ReadLine
Console.Write("Enter Data For Column 2: ")
Dim Data2 As String = Console.ReadLine
Console.WriteLine("{0,-20} {1,-10} {2,-10}", "{Data Type}", "{Column 1}", "{Column 2}")
Console.WriteLine("{0,-20} {1,-10} {2,-10}", "Data Entered:", Data1, Data2)

It should look like this:
You may be looking for auto-fill
:
grid-template-columns: repeat(auto-fill, 186px);
Demo: http://codepen.io/alanbuchanan/pen/wJRMox
To use up the available space more efficiently, you could use minmax
, and pass in auto
as the second argument:
grid-template-columns: repeat(auto-fill, minmax(186px, auto));
Demo: http://codepen.io/alanbuchanan/pen/jBXWLR
If you don't want the empty columns, you could use auto-fit
instead of auto-fill
.
div[disabled]
{
pointer-events: none;

Fix this by moving my jdk folder to other disk
Note that according to the CSS3 spec, you do NOT have to wrap your layout in a table-style element. The browser will infer the existence of containing elements if they do not exist.
Another way is creating a system unit for your app. create a "XXX.service" file in "/etc/systemd/system" folder, similar to this:
[Unit]
Description=swagger
After=network.target
[Service]
ExecStart=/usr/bin/http-server /home/swagger/swagger-editor &
WorkingDirectory=/home/swagger
Restart=always
RestartSec=30
[Install]
WantedBy=multi-user.target
A benefit is the app will run as a service, it automatically restarts if it crashed.
You can also use sytemctl to manage it:
systemctl start XXX
to start the service, systemctl stop XXX
to stop it and systemctl enable XXX
to automatically start the app when system boots.
I just tried with Git 2.30.0 (released 2020-12-28).
This is NOT a full answer but a few useful tidbits nonetheless. (Feel free to cannibalize for your own answer.)
There's a documentation link when installing Git for Windows
This link takes you here: https://github.com/git-for-windows/git/wiki/Symbolic-Links
And this is quite a longish discussion.
Also symbolic links keep popping up in the release notes. As of 2.30.0 this here is still listed as a "Known issue":
On Windows 10 before 1703, or when Developer Mode is turned off, special permissions are required when cloning repositories with symbolic links, therefore support for symbolic links is disabled by default. Use
git clone -c core.symlinks=true <URL>
to enable it, see details here.
Strings are immutable so you can't insert characters into an existing string. You have to create a new string. You can use string concatenation to do what you want:
yourstring = "L" + yourstring + "LL"
Note that you can also create a string with n L
s by using multiplication:
m = 1
n = 2
yourstring = ("L" * m) + yourstring + ("L" * n)
To expand a little on Andrew's answer: The fact that regular expressions define extractors can be used to decompose the substrings matched by the regex very nicely using Scala's pattern matching, e.g.:
val Process = """([a-cA-C])([^\s]+)""".r // define first, rest is non-space
for (p <- Process findAllIn "aha bah Cah dah") p match {
case Process("b", _) => println("first: 'a', some rest")
case Process(_, rest) => println("some first, rest: " + rest)
// etc.
}
The compile()
method is always called at some point; it's the only way to create a Pattern object. So the question is really, why should you call it explicitly? One reason is that you need a reference to the Matcher object so you can use its methods, like group(int)
to retrieve the contents of capturing groups. The only way to get ahold of the Matcher object is through the Pattern object's matcher()
method, and the only way to get ahold of the Pattern object is through the compile()
method. Then there's the find()
method which, unlike matches()
, is not duplicated in the String or Pattern classes.
The other reason is to avoid creating the same Pattern object over and over. Every time you use one of the regex-powered methods in String (or the static matches()
method in Pattern), it creates a new Pattern and a new Matcher. So this code snippet:
for (String s : myStringList) {
if ( s.matches("\\d+") ) {
doSomething();
}
}
...is exactly equivalent to this:
for (String s : myStringList) {
if ( Pattern.compile("\\d+").matcher(s).matches() ) {
doSomething();
}
}
Obviously, that's doing a lot of unnecessary work. In fact, it can easily take longer to compile the regex and instantiate the Pattern object, than it does to perform an actual match. So it usually makes sense to pull that step out of the loop. You can create the Matcher ahead of time as well, though they're not nearly so expensive:
Pattern p = Pattern.compile("\\d+");
Matcher m = p.matcher("");
for (String s : myStringList) {
if ( m.reset(s).matches() ) {
doSomething();
}
}
If you're familiar with .NET regexes, you may be wondering if Java's compile()
method is related to .NET's RegexOptions.Compiled
modifier; the answer is no. Java's Pattern.compile()
method is merely equivalent to .NET's Regex constructor. When you specify the Compiled
option:
Regex r = new Regex(@"\d+", RegexOptions.Compiled);
...it compiles the regex directly to CIL byte code, allowing it to perform much faster, but at a significant cost in up-front processing and memory use--think of it as steroids for regexes. Java has no equivalent; there's no difference between a Pattern that's created behind the scenes by String#matches(String)
and one you create explicitly with Pattern#compile(String)
.
(EDIT: I originally said that all .NET Regex objects are cached, which is incorrect. Since .NET 2.0, automatic caching occurs only with static methods like Regex.Matches()
, not when you call a Regex constructor directly. ref)

Encoding "Mary had" to Base 64
In this example we are using a simple text string ("Mary had") but the principle holds no matter what the data is (e.g. graphics file). To convert each 24 bits of input data to 32 bits of output, Base 64 encoding splits the 24 bits into 4 chunks of 6 bits. The first problem we notice is that "Mary had" is not a multiple of 3 bytes - it is 8 bytes long. Because of this, the last group of bits is only 4 bits long. To remedy this we add two extra bits of '0' and remember this fact by putting a '=' at the end. If the text string to be converted to Base 64 was 7 bytes long, the last group would have had 2 bits. In this case we would have added four extra bits of '0' and remember this fact by putting '==' at the end.

Using axes objects is a great approach for this. It helps if you want to interact with multiple figures and sub-plots. To add and manipulate the axes objects directly:
import matplotlib.pyplot as plt
fig = plt.figure(figsize=(12,9))
signal_axes = fig.add_subplot(211)
signal_axes.plot(xs,rawsignal)
fft_axes = fig.add_subplot(212)
fft_axes.set_title("FFT")
fft_axes.set_autoscaley_on(False)
fft_axes.set_ylim([0,1000])
fft = scipy.fft(rawsignal)
fft_axes.plot(abs(fft))
plt.show()
There's an excellent module for flow control in node.js called asyncblock. If wrapping the code in a function is OK for your case, the following sample may be considered:
var asyncblock = require('asyncblock');
var exec = require('child_process').exec;
asyncblock(function (flow) {
exec('node -v', flow.add());
result = flow.wait();
console.log(result); // There'll be trailing \n in the output
// Some other jobs
console.log('More results like if it were sync...');
});
By default, the hr
element in Twitter Bootstrap CSS file has a top and bottom margin of 18px
. That's what creates a gap. If you want the gap to be smaller you'll need to adjust margin property of the hr
element.
In your example, do something like this:
.container hr {
margin: 2px 0;
}

If you use large values for the paddings (e.g. greater than 0.5em), you'll start to see the text that overflows the content(-box) area, and that might lead you to think that the height is not exactly x rows (that you set), but it is. To understand what's going on, you might want to check out The box model and box-sizing pages.
Three years late, but my Googling brought me here so hopefully my answer will be useful for someone else.
I just created a second option (which I hid with CSS) and used Javascript to move the s backwards and forwards between them.
<select multiple id="sel1">
<option class="set1">Blah</option>
</select>
<select multiple id="sel2" style="display:none">
<option class="set2">Bleh</option>
</select>
Something like that, and then something like this will move an item onto the list (i.e., make it visible). Obviously adapt the code as needed for your purpose.
$('#sel2 .set2').appendTo($('#sel1'))
If by any chance you landed on this thread and wondering why adapter.invaidate()
or adapter.clear()
methods are not present in your case then maybe because you might be using RecyclerView.Adapter
instead of BaseAdapter
which is used by the asker of this question. If clearing the list
or arraylist
not resolving your problem then it may happen that you are making two or more instances of the adapter
for ex.:
MainActivity
...
adapter = new CustomAdapter(list);
adapter.notifyDataSetChanged();
recyclerView.setAdapter(adapter);
...
and
SomeFragment
...
adapter = new CustomAdapter(newList);
adapter.notifyDataSetChanged();
...
If in the second case you are expecting a change in the list of inflated views in recycler view then it is not gonna happen as in the second time a new instance of the adapter
is created which is not attached to the recycler view. Setting notifyDataSetChanged
in the second adapter is not gonna change the content of recycer view. For that make a new instance of the recycler view in SomeFragment and attach it to the new instance of the adapter.
SomeFragment
...
recyclerView = new RecyclerView();
adapter = new CustomAdapter();
recyclerView.setAdapter(adapter);
...
Although, I don't recommend making multiple instances of the same adapter and recycler view.

Returning a list from apply
is a dangerous operation as the resulting object is not guaranteed to be either a Series or a DataFrame. And exceptions might be raised in certain cases. Let's walk through a simple example:
df = pd.DataFrame(data=np.random.randint(0, 5, (5,3)),
columns=['a', 'b', 'c'])
df
a b c
0 4 0 0
1 2 0 1
2 2 2 2
3 1 2 2
4 3 0 0
There are three possible outcomes with returning a list from apply
1) If the length of the returned list is not equal to the number of columns, then a Series of lists is returned.
df.apply(lambda x: list(range(2)), axis=1) # returns a Series
0 [0, 1]
1 [0, 1]
2 [0, 1]
3 [0, 1]
4 [0, 1]
dtype: object
2) When the length of the returned list is equal to the number of columns then a DataFrame is returned and each column gets the corresponding value in the list.
df.apply(lambda x: list(range(3)), axis=1) # returns a DataFrame
a b c
0 0 1 2
1 0 1 2
2 0 1 2
3 0 1 2
4 0 1 2
3) If the length of the returned list equals the number of columns for the first row but has at least one row where the list has a different number of elements than number of columns a ValueError is raised.
i = 0
def f(x):
global i
if i == 0:
i += 1
return list(range(3))
return list(range(4))
df.apply(f, axis=1)
ValueError: Shape of passed values is (5, 4), indices imply (5, 3)
Using apply
with axis=1 is very slow. It is possible to get much better performance (especially on larger datasets) with basic iterative methods.
Create larger dataframe
df1 = df.sample(100000, replace=True).reset_index(drop=True)
# apply is slow with axis=1
%timeit df1.apply(lambda x: mylist[x['col_1']: x['col_2']+1], axis=1)
2.59 s ± 76.8 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
# zip - similar to @Thomas
%timeit [mylist[v1:v2+1] for v1, v2 in zip(df1.col_1, df1.col_2)]
29.5 ms ± 534 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
@Thomas answer
%timeit list(map(get_sublist, df1['col_1'],df1['col_2']))
34 ms ± 459 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
Try this:
$("#test-element").on("click" ,function() {
alert("click");
});
The document way of doing it is weird too. That would make sense to me if used for a class selector, but in the case of an id you probably just have useless DOM traversing there. In the case of the id selector, you get that element instantly.
df.shape
, where df
is your DataFrame.
There is a very easy work around for this problem.
If you run a 10046 trace on your session (google this... too much to explain). You will see that before any DDL operation Oracle does the following:
LOCK TABLE 'TABLE_NAME' NO WAIT
So if another session has an open transaction you get an error. So the fix is... drum roll please. Issue your own lock before the DDL and leave out the 'NO WAIT'.
Special Note:
if you are doing splitting/dropping partitions oracle just locks the partition. -- so yo can just lock the partition subpartition.
So... The following steps fix the problem.
DML statements will 'wait' or as developers call it 'hang' while the table is locked.
I use this in code that runs from a job to drop partitions. It works fine. It is in a database that is constantly inserting at a rate of several hundred inserts/second. No errors.
if you are wondering. Doing this in 11g. I have done this in 10g before as well in the past.
I had this problem too (encountered through Macports compilers). Previous versions of Xcode would let you install command line tools through xcode/Preferences, but xcode5 doesn't give a command line tools option in the GUI, that so I assumed it was automatically included now. Try running this command:
xcode-select --install

sudo apt-get install libc6-dev
(as per this comment)
apk add libc-dev
For Registry Key you can check if it is null after getting it. It will be, if it doesn't exist.
For Registry Value you can get names of Values for the current key and check if this array contains the needed Value name.
Example:
public static bool checkMachineType()
{
RegistryKey winLogonKey = Registry.LocalMachine.OpenSubKey(@"System\CurrentControlSet\services\pcmcia", true);
return (winLogonKey.GetValueNames().Contains("Start"));
}
It's not clear whether you're asking this because you are new to programming, but if that's the case then you should probably read this article on loops and indeed read some basic materials on programming.
If you already know about control structures and you want the R-specific implementation details then there are dozens of tutorials around, such as this one. The other answer uses replicate
and colMeans
, which is idiomatic when writing in R and probably blazing fast as well, which is important if you want 10,000 iterations.
However, one more general and (for beginners) straightforward way to approach problems of this sort would be to use a for
loop.
> for (ii in 1:5) { + print(ii) + } [1] 1 [1] 2 [1] 3 [1] 4 [1] 5 >
So in your case, if you just wanted to print the mean of your Tandem
object 5 times:
for (ii in 1:5) { Tandem <- sample(OUT, size = 815, replace = TRUE, prob = NULL) TandemMean <- mean(Tandem) print(TandemMean) }
As mentioned above, replicate
is a more natural way to deal with this specific problem using R. Either way, if you want to store the results - which is surely the case - you'll need to start thinking about data structures like vectors and lists. Once you store something you'll need to be able to access it to use it in future, so a little knowledge is vital.
set.seed(1234) OUT <- runif(100000, 1, 2) tandem <- list() for (ii in 1:10000) { tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) } tandem[1] tandem[100] tandem[20:25]
...creates this output:
> set.seed(1234) > OUT <- runif(100000, 1, 2) > tandem <- list() > for (ii in 1:10000) { + tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) + } > > tandem[1] [[1]] [1] 1.511923 > tandem[100] [[1]] [1] 1.496777 > tandem[20:25] [[1]] [1] 1.500669 [[2]] [1] 1.487552 [[3]] [1] 1.503409 [[4]] [1] 1.501362 [[5]] [1] 1.499728 [[6]] [1] 1.492798 >
You will have to open the file in one way or another if you want to access the data within it. Obviously, one way is to open it in your Excel application instance, e.g.:-
(untested code)
Dim wbk As Workbook
Set wbk = Workbooks.Open("C:\myworkbook.xls")
' now you can manipulate the data in the workbook anyway you want, e.g. '
Dim x As Variant
x = wbk.Worksheets("Sheet1").Range("A6").Value
Call wbk.Worksheets("Sheet2").Range("A1:G100").Copy
Call ThisWorbook.Worksheets("Target").Range("A1").PasteSpecial(xlPasteValues)
Application.CutCopyMode = False
' etc '
Call wbk.Close(False)
Another way to do it would be to use the Excel ADODB provider to open a connection to the file and then use SQL to select data from the sheet you want, but since you are anyway working from within Excel I don't believe there is any reason to do this rather than just open the workbook. Note that there are optional parameters for the Workbooks.Open() method to open the workbook as read-only, etc.
You can take timestamp snapshots before and after, then repeat the experiments several times to average to results. There are also profilers that can do this for you.
With System.currentTimeMillis()
class TimeTest1 {
public static void main(String[] args) {
long startTime = System.currentTimeMillis();
long total = 0;
for (int i = 0; i < 10000000; i++) {
total += i;
}
long stopTime = System.currentTimeMillis();
long elapsedTime = stopTime - startTime;
System.out.println(elapsedTime);
}
}
With a StopWatch class
You can use this StopWatch
class, and call start()
and stop
before and after the method.
class TimeTest2 {
public static void main(String[] args) {
Stopwatch timer = new Stopwatch().start();
long total = 0;
for (int i = 0; i < 10000000; i++) {
total += i;
}
timer.stop();
System.out.println(timer.getElapsedTime());
}
}

I had a task on BE side to find all entities from a repo, and to add a new property url and to return to controller layer. This is how I achieved it (thanks to Ajedi32's response):
async findAll(): Promise<ImageResponse[]> {
const images = await this.imageRepository.find(); // This is an array of type Image (DB entity)
const host = this.request.get('host');
const mappedImages = await Promise.all(images.map(image => ({...image, url: `http://${host}/images/${image.id}`}))); // This is an array of type Object
return plainToClass(ImageResponse, mappedImages); // Result is an array of type ImageResponse
}
Note: Image (entity) doesn't have property url, but ImageResponse - has
For Chart.js 2.x refer to andyhasit's answer - https://stackoverflow.com/a/36954319/360067
For Chart.js 1.x, you can tweak the options and extend the chart type to do this, like so
Chart.types.Line.extend({
name: "LineAlt",
draw: function () {
Chart.types.Line.prototype.draw.apply(this, arguments);
var ctx = this.chart.ctx;
ctx.save();
// text alignment and color
ctx.textAlign = "center";
ctx.textBaseline = "bottom";
ctx.fillStyle = this.options.scaleFontColor;
// position
var x = this.scale.xScalePaddingLeft * 0.4;
var y = this.chart.height / 2;
// change origin
ctx.translate(x, y);
// rotate text
ctx.rotate(-90 * Math.PI / 180);
ctx.fillText(this.datasets[0].label, 0, 0);
ctx.restore();
}
});
calling it like this
var ctx = document.getElementById("myChart").getContext("2d");
var myLineChart = new Chart(ctx).LineAlt(data, {
// make enough space on the right side of the graph
scaleLabel: " <%=value%>"
});
Notice the space preceding the label value, this gives us space to write the y axis label without messing around with too much of Chart.js internals

Your question is incorrect; the error you see is not a result of how you built python, but of a confusion between byte strings and unicode strings.
Byte strings (e.g. "foo", or 'bar', in python syntax) are sequences of octets; numbers from 0-255. Unicode strings (e.g. u"foo" or u'bar') are sequences of unicode code points; numbers from 0-1112064. But you appear to be interested in the character é, which (in your terminal) is a multi-byte sequence that represents a single character.
Instead of ord(u'é')
, try this:
>>> [ord(x) for x in u'é']
That tells you which sequence of code points "é" represents. It may give you [233], or it may give you [101, 770].
Instead of chr()
to reverse this, there is unichr()
:
>>> unichr(233)
u'\xe9'
This character may actually be represented either a single or multiple unicode "code points", which themselves represent either graphemes or characters. It's either "e with an acute accent (i.e., code point 233)", or "e" (code point 101), followed by "an acute accent on the previous character" (code point 770). So this exact same character may be presented as the Python data structure u'e\u0301'
or u'\u00e9'
.
Most of the time you shouldn't have to care about this, but it can become an issue if you are iterating over a unicode string, as iteration works by code point, not by decomposable character. In other words, len(u'e\u0301') == 2
and len(u'\u00e9') == 1
. If this matters to you, you can convert between composed and decomposed forms by using unicodedata.normalize
.
The Unicode Glossary can be a helpful guide to understanding some of these issues, by pointing how how each specific term refers to a different part of the representation of text, which is far more complicated than many programmers realize.

As suggested by A Star, I always use something along the lines of:
DATE(NOW()) - INTERVAL 1 MONTH
Similarly you can do:

and so on. Much easier than typing DATE_ADD
or DATE_SUB
all the time :)!
I had a similar issue with an integer that could be legitimately assigned 0 in Access VBA. None of the above solutions worked for me.
At first I just used a boolean var and IF statement:
Dim i as integer, bol as boolean
If bol = false then
i = ValueIWantToAssign
bol = True
End If
In my case, my integer variable assignment was within a for loop and another IF statement, so I ended up using "Exit For" instead as it was more concise.
Like so:
Dim i as integer
ForLoopStart
If ConditionIsMet Then
i = ValueIWantToAssign
Exit For
End If
ForLoopEnd
Simply use:
int ans = Integer.parseInt( JOptionPane.showInputDialog(frame,
"Text",
JOptionPane.INFORMATION_MESSAGE,
null,
null,

we can let the SQL to generate create table script by navigating as

Edit Jan 2021: The React Native docs currently recommend React Native WebView:
<WebView
originWhitelist={['*']}
source={{ html: '<p>Here I am</p>' }}
/>
https://github.com/react-native-webview/react-native-webview
Edit March 2017: the html
prop has been deprecated. Use source
instead:
<WebView source={{html: '<p>Here I am</p>'}} />
https://facebook.github.io/react-native/docs/webview.html#html
Thanks to Justin for pointing this out.
Edit Feb 2017: the PR was accepted a while back, so to render HTML in React Native, simply:
<WebView html={'<p>Here I am</p>'} />
Original Answer:
I don't think this is currently possible. The behavior you're seeing is expected, since the Text component only outputs... well, text. You need another component that outputs HTML - and that's the WebView.
Unfortunately right now there's no way of just directly setting the HTML on this component:

However I've just created this PR which implements a basic version of this feature so hopefully it'll land in some form soonish.
Try GIT_CURL_VERBOSE=1 git push
...Your problem may occur due to proxy settings, for instance if git is trying to reach github.com via a proxy server and the proxy is not responding.
With GIT_CURL_VERBOSE=1 it will show the target IP address and some information. You can compare this IP address with the output of the command: host www.github.com
. If these IPs are different then you can set https_proxy=""
and try again.
Another mac solution similar to osxfuse is to just use Transmit FTP client from Panic Software, which allows you to mount a remote folder as a local disk. It supports SFTP, which is very secure.
You can turn the values of an Object into an array and test that a string is present. It assumes that the Object is not nested and the string is an exact match:
var obj = { a: 'test1', b: 'test2' };
if (Object.values(obj).indexOf('test1') > -1) {
console.log('has test1');
}
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/values
you could do something like (below)
var query = from p in context.T1
join q in context.T2
on
new { p.Col1, p.Col2 }
equals
new { q.Col1, q.Col2 }
select new {p...., q......};
Hi you can create a customized build on bootstrap, just change the font name in the following pages
Bootstrap 2.3.2 http://getbootstrap.com/2.3.2/customize.html#variables
Bootstrap 3 http://getbootstrap.com/customize/#less-variables
After that, make sure to use proper @font-face in a css file and link that to your page. Or you could use font kit generators.
personally I favor validating without a callback:
public bool ValidateSchema(string xmlPath, string xsdPath)
{
XmlDocument xml = new XmlDocument();
xml.Load(xmlPath);
xml.Schemas.Add(null, xsdPath);
try
{
xml.Validate(null);
}
catch (XmlSchemaValidationException)
{
return false;
}
return true;
}
(see Timiz0r's post in Synchronous XML Schema Validation? .NET 3.5)
This has reared it's head again in Visual Studio 2017, in this case the cause is the Application Insights process ServiceHub.DataWarehouseHost.exe.
There is a workaround discussed in the thread warning MSB3026: Could not copy "obj\Debug\netcoreapp1.1\src.pdb" to "bin\Debug\netcoreapp1.1\src.pdb", which is to add a pre-build event to the project to kill the process every time the project is built. Quoting from that link:
- Right click properties on project
- Choose properties
- Build Events
- Pre-build event command line
taskkill /IM ServiceHub.DataWarehouseHost.exe /F 2>nul 1>nul
Exit 0
- Save and build
This error really just has to do with the file Path,thats all you have to check,for me my parent folder was "Layouts" but my actual file was layout.html
,my path had layouts on both,once i corrected that error was gone.
The two valid mains are int main()
and int main(int, char*[])
. Any thing else may or may not compile. If main
doesn't explicitly return a value, 0 is implicitly returned.
You can use $.each() to iterate over the array and locate the object you're interested in:
$.each(projects, function() {
if (this.value == "jquery-ui") {
this.desc = "Your new description";
}
});
I was facing same issue for changing default gradle version from 5.0 to 4.7, Below are the steps to change default gradle version in intellij
1) Change gradle version in gradle/wrapper/gradle-wrapper.properties in this property distributionUrl
2) Hit refresh button in gradle projects menu so that it will start downloading new gradle zip version
Number of .parent a
elements that have an id
attribute:
$('.parent a[id]').length
In my case, just using flex-shrink: 0
didn't work. But adding flex-grow: 1
to it worked.
.item {
flex-shrink: 0;
flex-grow: 1;
}
On newer version of cpanel: search ini
The -i
flag specifies the private key (.pem file) to use. If you don't specify that flag (as in your first command) it will use your default ssh key (usually under ~/.ssh/
).
So in your first command, you are actually asking scp
to upload the .pem file itself using your default ssh key. I don't think that is what you want.
Try instead with:
scp -r -i /Applications/XAMPP/htdocs/keypairfile.pem uploads/* ec2-user@publicdns:/var/www/html/uploads
{% for i in yourlist %}
{% for k,v in i.items() %}
{# do what you want here #}
{% endfor %}
{% endfor %}
Instead of letting the business layer decide how it’s best to fetch all the associations that are needed by the View layer, OSIV (Open Session in View) forces the Persistence Context to stay open so that the View layer can trigger the Proxy initialization, as illustrated by the following diagram.
OpenSessionInViewFilter
calls the openSession
method of the underlying SessionFactory
and obtains a new Session
.Session
is bound to the TransactionSynchronizationManager
.OpenSessionInViewFilter
calls the doFilter
of the javax.servlet.FilterChain
object reference and the request is further processedDispatcherServlet
is called, and it routes the HTTP request to the underlying PostController
.PostController
calls the PostService
to get a list of Post
entities.PostService
opens a new transaction, and the HibernateTransactionManager
reuses the same Session
that was opened by the OpenSessionInViewFilter
.PostDAO
fetches the list of Post
entities without initializing any lazy association.PostService
commits the underlying transaction, but the Session
is not closed because it was opened externally.DispatcherServlet
starts rendering the UI, which, in turn, navigates the lazy associations and triggers their initialization.OpenSessionInViewFilter
can close the Session
, and the underlying database connection is released as well.At first glance, this might not look like a terrible thing to do, but, once you view it from a database perspective, a series of flaws start to become more obvious.
The service layer opens and closes a database transaction, but afterward, there is no explicit transaction going on. For this reason, every additional statement issued from the UI rendering phase is executed in auto-commit mode. Auto-commit puts pressure on the database server because each transaction issues a commit at end, which can trigger a transaction log flush to disk. One optimization would be to mark the Connection
as read-only which would allow the database server to avoid writing to the transaction log.
There is no separation of concerns anymore because statements are generated both by the service layer and by the UI rendering process. Writing integration tests that assert the number of statements being generated requires going through all layers (web, service, DAO) while having the application deployed on a web container. Even when using an in-memory database (e.g. HSQLDB) and a lightweight webserver (e.g. Jetty), these integration tests are going to be slower to execute than if layers were separated and the back-end integration tests used the database, while the front-end integration tests were mocking the service layer altogether.
The UI layer is limited to navigating associations which can, in turn, trigger N+1 query problems. Although Hibernate offers @BatchSize
for fetching associations in batches, and FetchMode.SUBSELECT
to cope with this scenario, the annotations are affecting the default fetch plan, so they get applied to every business use case. For this reason, a data access layer query is much more suitable because it can be tailored to the current use case data fetch requirements.
Last but not least, the database connection is held throughout the UI rendering phase which increases connection lease time and limits the overall transaction throughput due to congestion on the database connection pool. The more the connection is held, the more other concurrent requests are going to wait to get a connection from the pool.
Unfortunately, OSIV (Open Session in View) is enabled by default in Spring Boot, and OSIV is really a bad idea from a performance and scalability perspective.
So, make sure that in the application.properties
configuration file, you have the following entry:
spring.jpa.open-in-view=false
This will disable OSIV so that you can handle the LazyInitializationException
the right way.
Starting with version 2.0, Spring Boot issues a warning when OSIV is enabled by default, so you can discover this problem long before it affects a production system.
It may differ between versions of xcodes. Best approach is to go xcode preference page and from tab "Locations", directly open "Derived Data" directory.
svn move
— Move a file or directory.
I had the same problem. I tried installing Visual Studio 2010 SP1 but it didn't worked.
Finally I get Microsoft.Web.Infrastructure.dll from the colleague. You can find the dll into your friends PC where the project is perfectly working. Try to search dll into Temp/Temporary ASP.NET Files. Go to Temp using %temp% into run window.
After getting dll into your pc, just add reference to your project and it will work.
Here, &
is not used as an operator. As part of function or variable declarations, &
denotes a reference. The C++ FAQ Lite has a pretty nifty chapter on references.
You can use Reflections framework for this
import static org.reflections.ReflectionUtils.*;
Set<Method> getters = ReflectionUtils.getAllMethods(someClass,
withModifier(Modifier.PUBLIC), withPrefix("get"), withAnnotation(annotation));
The accepted answer did not work for me when dealing with text-based lists of variable lengths. Here is an alternate approach that did work for me.
l = ['aaa', 'bb', 'cccccc', ['xx', 'yyyyyyy']]
flat_list = [item for sublist in l for item in sublist]
print(flat_list)
['a', 'a', 'a', 'b', 'b', 'c', 'c', 'c', 'c', 'c', 'c', 'xx', 'yyyyyyy']
flat_list = []
_ = [flat_list.extend(item) if isinstance(item, list) else flat_list.append(item) for item in l if item]
print(flat_list)
['aaa', 'bb', 'cccccc', 'xx', 'yyyyyyy']
In my case I had to wait for a user interaction, so I set a click
or touchend
listener.
const isMobile = navigator.maxTouchPoints || "ontouchstart" in document.documentElement;
function play(){
audioEl.play()
}
document.body.addEventListener(isMobile ? "touchend" : "click", play, { once: true });
Unfortunately I ran into the same issue and I was head scratching why this is happening. I almost tried everything on this page and but none worked for me.
So , I tried to go the root of this problem; and the problem was (Atleast for me) that I was trying to open a maven project but pom file was not identified. So right clicking on the pom file and choosing "add as maven project" and then right clicking on the project -> Maven -> Reimport did all the magic for me :)
Hopefully this can be helpful for someone.
What may be happening is that your console is closing before you get a chance to see the output. I would add Console.ReadLine();
after your Console.WriteLine("Hello World");
so your code would look something like this:
static void Main(string[] args)
{
Console.WriteLine("Hello World");
Console.ReadLine();
}
This way, the console will display "Hello World" and a blinking cursor underneath. The Console.ReadLine();
is the key here, the program waits for the users input before closing the console window.
Well, the code you've given is invalid to start with - List
is a generic type, and it has an Add
method instead of add
etc.
But you could do something like:
List<Person> list = new List<Person>
{
new person{ID=1,Name="jhon",salary=2500},
new person{ID=2,Name="Sena",salary=1500},
new person{ID=3,Name="Max",salary=5500}.
new person{ID=4,Name="Gen",salary=3500}
};
// The "Where" LINQ operator filters a sequence
var highEarners = list.Where(p => p.salary > 3000);
foreach (var person in highEarners)
{
Console.WriteLine(person.Name);
}
If you want to learn details of what all the LINQ operators do, and how they can be implemented in LINQ to Objects, you might be interested in my Edulinq blog series.
Check out Open Terminal Here. It may be the most similar to "Open Command Window Here." I used >cdto
and this is very similar but this seems to be a little better at dealing with Spaces... but not perfect.
What it has that is very nice is the ability to "detect key-down events at the start of the application and used them to modify the behavior of the script" allowing the script to open a new tab in the front most terminal window when invoked by holding down ? key. Neat trick.
Also note PCheese's answer; it is probably more useful for heavy terminal users!
The error is:
Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])
In JSON, platforms
look like this:
"platforms": [
{
"platform": "iphone"
},
{
"platform": "ipad"
},
{
"platform": "android_phone"
},
{
"platform": "android_tablet"
}
]
So try change your pojo to something like this:
private List platforms;
public List getPlatforms(){
return this.platforms;
}
public void setPlatforms(List platforms){
this.platforms = platforms;
}
EDIT: you will need change mobile_networks
too. Will look like this:
private List mobile_networks;
public List getMobile_networks() {
return mobile_networks;
}
public void setMobile_networks(List mobile_networks) {
this.mobile_networks = mobile_networks;
}
You have to add Imports System.Runtime.InteropServices
to the top of your source file.
Alternatively, you can fully qualify attribute name:
<System.Runtime.InteropService.DllImport("user32.dll", _
SetLastError:=True, CharSet:=CharSet.Auto)> _
next
- it's like return
, but for blocks! (So you can use this in any proc
/lambda
too.)
That means you can also say next n
to "return" n
from the block. For instance:
puts [1, 2, 3].map do |e|
next 42 if e == 2
e
end.inject(&:+)
This will yield 46
.
Note that return
always returns from the closest def
, and never a block; if there's no surrounding def
, return
ing is an error.
Using return
from within a block intentionally can be confusing. For instance:
def my_fun
[1, 2, 3].map do |e|
return "Hello." if e == 2
e
end
end
my_fun
will result in "Hello."
, not [1, "Hello.", 2]
, because the return
keyword pertains to the outer def
, not the inner block.
To take the definitions the other mentioned earlier a bit further, how about this perspective...
LDAP is Lightweight Directory Access Protocol. DAP, is an X.500 notion, and in X.500 is VERY heavy weight! (It sort of requires a full 7 layer ISO network stack, which basically only IBM's SNA protocol ever realistically implemented).
There are many other approaches to DAP. Novell has one called NDAP (NCP Novell Core Protocols are the transport, and NDAP is how it reads the directory).
LDAP is just a very lightweight DAP, as the name suggests.
MySQL server 5.7 was already installed by default on my new Linux Mint 19.
But, what's the MySQL root
password? It turns out that:
The default installation uses auth_socket
for authentication, in lieu of passwords!
It allows a password-free login, provided that one is logged into the Linux system with the same user name. To login as the MySQL root user
, one can use sudo:
sudo mysql --user=root
But how to then change the root password? To illustrate what's going on, I created a new user "me", with full privileges, with:
mysql> CREATE USER 'me'@'localhost' IDENTIFIED BY 'my_new_password';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'me'@'localhost' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
Comparing "me" with "root":
mysql> SELECT user, plugin, HEX(authentication_string) FROM mysql.user WHERE user = 'me' or user = 'root';
+------+-----------------------+----------------------------------------------------------------------------+
| user | plugin | HEX(authentication_string) |
+------+-----------------------+----------------------------------------------------------------------------+
| root | auth_socket | |
| me | mysql_native_password | 2A393846353030304545453239394634323734333139354241344642413245373537313... |
+------+-----------------------+----------------------------------------------------------------------------+
Because it's using auth_socket, the root password cannot be changed: the SET PASSWORD
command fails, and mysql_secure_installation
desn't attain anything...
==> To zap this alternate authentication mode and return the MySQL root
user to using passwords:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'SOME_NEW_ROOT_PASSWORD';

I couldn't find a better solution than creating a extension method to convert a Dictionary to QueryStringFormat. The solution proposed by Waleed A.K. is good as well.
Follow my solution:
Create the extension method:
public static class DictionaryExt
{
public static string ToQueryString<TKey, TValue>(this Dictionary<TKey, TValue> dictionary)
{
return ToQueryString<TKey, TValue>(dictionary, "?");
}
public static string ToQueryString<TKey, TValue>(this Dictionary<TKey, TValue> dictionary, string startupDelimiter)
{
string result = string.Empty;
foreach (var item in dictionary)
{
if (string.IsNullOrEmpty(result))
result += startupDelimiter; // "?";
else
result += "&";
result += string.Format("{0}={1}", item.Key, item.Value);
}
return result;
}
}
And them:
var param = new Dictionary<string, string>
{
{ "param1", "value1" },
{ "param2", "value2" },
};
param.ToQueryString(); //By default will add (?) question mark at begining
//"?param1=value1¶m2=value2"
param.ToQueryString("&"); //Will add (&)
//"¶m1=value1¶m2=value2"
param.ToQueryString(""); //Won't add anything
//"param1=value1¶m2=value2"
With:
FILES = $(shell ls)
indented underneath all
like that, it's a build command. So this expands $(shell ls)
, then tries to run the command FILES ...
.
If FILES
is supposed to be a make
variable, these variables need to be assigned outside the recipe portion, e.g.:
FILES = $(shell ls)
all:
echo $(FILES)
Of course, that means that FILES
will be set to "output from ls
" before running any of the commands that create the .tgz files. (Though as Kaz notes the variable is re-expanded each time, so eventually it will include the .tgz files; some make variants have FILES := ...
to avoid this, for efficiency and/or correctness.1)
If FILES
is supposed to be a shell variable, you can set it but you need to do it in shell-ese, with no spaces, and quoted:
all:
FILES="$(shell ls)"
However, each line is run by a separate shell, so this variable will not survive to the next line, so you must then use it immediately:
FILES="$(shell ls)"; echo $$FILES
This is all a bit silly since the shell will expand *
(and other shell glob expressions) for you in the first place, so you can just:
echo *
as your shell command.
Finally, as a general rule (not really applicable to this example): as esperanto notes in comments, using the output from ls
is not completely reliable (some details depend on file names and sometimes even the version of ls
; some versions of ls
attempt to sanitize output in some cases). Thus, as l0b0 and idelic note, if you're using GNU make you can use $(wildcard)
and $(subst ...)
to accomplish everything inside make
itself (avoiding any "weird characters in file name" issues). (In sh
scripts, including the recipe portion of makefiles, another method is to use find ... -print0 | xargs -0
to avoid tripping over blanks, newlines, control characters, and so on.)
1The GNU Make documentation notes further that POSIX make added ::=
assignment in 2012. I have not found a quick reference link to a POSIX document for this, nor do I know off-hand which make
variants support ::=
assignment, although GNU make does today, with the same meaning as :=
, i.e., do the assignment right now with expansion.
Note that VAR := $(shell command args...)
can also be spelled VAR != command args...
in several make
variants, including all modern GNU and BSD variants as far as I know. These other variants do not have $(shell)
so using VAR != command args...
is superior in both being shorter and working in more variants.
You can't just return an array of objects because there's nothing telling React how to render that. You'll need to return an array of components or elements like:
render: function() {
return (
<span>
// This will go through all the elements in arrayFromJson and
// render each one as a <SomeComponent /> with data from the object
{this.state.arrayFromJson.map(function(object) {
return (
<SomeComponent key={object.id} data={object} />
);
})}
</span>
);
}
Panagiotis Kanavos is right, sometimes copy and paste T-SQL can make appear unwanted characters...
I finally found a simple and fast way (only Notepad++ needed) to detect which character is wrong, without having to manually rewrite the whole statement: there is no need to save any file to disk.
It's pretty quick, in Notepad++:
You should easily find the wrong character(s)
From man nano
:
-T cols (--tabsize=cols)
Set the size (width) of a tab to cols columns.
The value of cols must be greater than 0. The default value is 8.
-E (--tabstospaces)
Convert typed tabs to spaces.
For example, to set the tab size to 4, replace tabs with spaces, and edit the file "foo.txt", you would run the command:
nano -ET4 foo.txt
From man nanorc
:
set tabsize n
Use a tab size of n columns. The value of n must be greater than 0.
The default value is 8.
set/unset tabstospaces
Convert typed tabs to spaces.
Edit your ~/.nanorc
file (create it if it does not exist), and add those commands to it. For example:
set tabsize 4
set tabstospaces
Nano will use these settings by default whenever it is launched, but command-line flags will override them.
Open git view :
1- select your project and choose merge 2- Select remote tracking 3- click ok
Git will merge the remote branch with local repository
4- then push
If you need a lot of decimal numbers, in this example 17, I share with you MySql code:
This is the calculate:
=(9/1147)*100
SELECT TRUNCATE(((CAST(9 AS DECIMAL(30,20))/1147)*100),17);
You can just read the data into a list and insert the new record where you want.
names = []
with open('names.txt', 'r+') as fd:
for line in fd:
names.append(line.split(' ')[-1].strip())
names.insert(2, "Charlie") # element 2 will be 3. in your list
fd.seek(0)
fd.truncate()
for i in xrange(len(names)):
fd.write("%d. %s\n" %(i + 1, names[i]))

I also want to know is it possible to push the compiled binary into android device or AVD and run using the terminal of the android device or AVD?
here you can see NestedVM
NestedVM provides binary translation for Java Bytecode. This is done by having GCC compile to a MIPS binary which is then translated to a Java class file. Hence any application written in C, C++, Fortran, or any other language supported by GCC can be run in 100% pure Java with no source changes.
Example: Cross compile Hello world C program and run it on android

Data::Dumper is your friend.
use Data::Dumper;
my %hash = ('abc' => 123, 'def' => [4,5,6]);
print Dumper(\%hash);
will output
$VAR1 = {
'def' => [
4,
5,
6
],
'abc' => 123
};
The recommended way to do this is to use LocationClient
:
First, define location update interval values. Adjust this to your needs.
private static final int MILLISECONDS_PER_SECOND = 1000;
private static final long UPDATE_INTERVAL = MILLISECONDS_PER_SECOND * UPDATE_INTERVAL_IN_SECONDS;
private static final int FASTEST_INTERVAL_IN_SECONDS = 1;
private static final long FASTEST_INTERVAL = MILLISECONDS_PER_SECOND * FASTEST_INTERVAL_IN_SECONDS;
Have your Activity
implement GooglePlayServicesClient.ConnectionCallbacks
, GooglePlayServicesClient.OnConnectionFailedListener
, and LocationListener
.
public class LocationActivity extends Activity implements
GooglePlayServicesClient.ConnectionCallbacks, GooglePlayServicesClient.OnConnectionFailedListener, LocationListener {}
Then, set up a LocationClient
in the onCreate()
method of your Activity
:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mLocationClient = new LocationClient(this, this, this);
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
mLocationRequest.setInterval(UPDATE_INTERVAL);
mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
}
Add the required methods to your Activity
; onConnected()
is the method that is called when the LocationClient
connects. onLocationChanged()
is where you'll retrieve the most up-to-date location.
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Log.w(TAG, "Location client connection failed");
}
@Override
public void onConnected(Bundle dataBundle) {
Log.d(TAG, "Location client connected");
mLocationClient.requestLocationUpdates(mLocationRequest, this);
}
@Override
public void onDisconnected() {
Log.d(TAG, "Location client disconnected");
}
@Override
public void onLocationChanged(Location location) {
if (location != null) {
Log.d(TAG, "Updated Location: " + Double.toString(location.getLatitude()) + "," + Double.toString(location.getLongitude()));
} else {
Log.d(TAG, "Updated location NULL");
}
}
Be sure to connect/disconnect the LocationClient
so it's only using extra battery when absolutely necessary and so the GPS doesn't run indefinitely. The LocationClient
must be connected in order to get data from it.
public void onResume() {
super.onResume();
mLocationClient.connect();
}
public void onStop() {
if (mLocationClient.isConnected()) {
mLocationClient.removeLocationUpdates(this);
}
mLocationClient.disconnect();
super.onStop();
}
Get the user's location. First try using the LocationClient
; if that fails, fall back to the LocationManager
.
public Location getLocation() {
if (mLocationClient != null && mLocationClient.isConnected()) {
return mLocationClient.getLastLocation();
} else {
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
if (locationManager != null) {
Location lastKnownLocationGPS = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (lastKnownLocationGPS != null) {
return lastKnownLocationGPS;
} else {
return locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
}
} else {
return null;
}
}
}
Give this a shot:
has_many :jobs, foreign_key: "user_id", class_name: "Task"

hi here is a simple example: <div id="test">content</div>
and
var test = 5;
document.getElementById('test').innerHTML = test;
and you can test it here : http://jsfiddle.net/SLbKX/
Please check in logs if you have http.HttpWagon$__sisu1:Cannot find 'basicAuthScope' this error or warning also, if so you need to use maven 3.2.5 version, which will resolve error.
dir has been mentioned, but that'll only give you the attributes' names. If you want their values as well try __dict__.
class O:
def __init__ (self):
self.value = 3
o = O()
Here is the output:
>>> o.__dict__
{'value': 3}

document.cookie = "test1=Hello";
document.cookie = "test2=World";
var cookieValue = document.cookie.replace(/(?:(?:^|.*;\s*)test2\s*\=\s*([^;]*).*$)|^.*$/, "$1");
alert(cookieValue);
MySQL 5.7 supports computed columns. They call it "Generated Columns" and the syntax is a little weird, but it supports the same options I see in other databases.
