I've created a new class to handle binding RadioButtons and CheckBoxes to enums. It works for flagged enums (with multiple checkbox selections) and non-flagged enums for single-selection checkboxes or radio buttons. It also requires no ValueConverters at all.
This might look more complicated at first, however, once you copy this class into your project, it's done. It's generic so it can easily be reused for any enum.
public class EnumSelection<T> : INotifyPropertyChanged where T : struct, IComparable, IFormattable, IConvertible
{
private T value; // stored value of the Enum
private bool isFlagged; // Enum uses flags?
private bool canDeselect; // Can be deselected? (Radio buttons cannot deselect, checkboxes can)
private T blankValue; // what is considered the "blank" value if it can be deselected?
public EnumSelection(T value) : this(value, false, default(T)) { }
public EnumSelection(T value, bool canDeselect) : this(value, canDeselect, default(T)) { }
public EnumSelection(T value, T blankValue) : this(value, true, blankValue) { }
public EnumSelection(T value, bool canDeselect, T blankValue)
{
if (!typeof(T).IsEnum) throw new ArgumentException($"{nameof(T)} must be an enum type"); // I really wish there was a way to constrain generic types to enums...
isFlagged = typeof(T).IsDefined(typeof(FlagsAttribute), false);
this.value = value;
this.canDeselect = canDeselect;
this.blankValue = blankValue;
}
public T Value
{
get { return value; }
set
{
if (this.value.Equals(value)) return;
this.value = value;
OnPropertyChanged();
OnPropertyChanged("Item[]"); // Notify that the indexer property has changed
}
}
[IndexerName("Item")]
public bool this[T key]
{
get
{
int iKey = (int)(object)key;
return isFlagged ? ((int)(object)value & iKey) == iKey : value.Equals(key);
}
set
{
if (isFlagged)
{
int iValue = (int)(object)this.value;
int iKey = (int)(object)key;
if (((iValue & iKey) == iKey) == value) return;
if (value)
Value = (T)(object)(iValue | iKey);
else
Value = (T)(object)(iValue & ~iKey);
}
else
{
if (this.value.Equals(key) == value) return;
if (!value && !canDeselect) return;
Value = value ? key : blankValue;
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged([CallerMemberName] string propertyName = "")
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
And for how to use it, let's say you have an enum for running a task manually or automatically, and can be scheduled for any days of the week, and some optional options...
public enum StartTask
{
Manual,
Automatic
}
[Flags()]
public enum DayOfWeek
{
Sunday = 1 << 0,
Monday = 1 << 1,
Tuesday = 1 << 2,
Wednesday = 1 << 3,
Thursday = 1 << 4,
Friday = 1 << 5,
Saturday = 1 << 6
}
public enum AdditionalOptions
{
None = 0,
OptionA,
OptionB
}
Now, here's how easy it is to use this class:
public class MyViewModel : ViewModelBase
{
public MyViewModel()
{
StartUp = new EnumSelection<StartTask>(StartTask.Manual);
Days = new EnumSelection<DayOfWeek>(default(DayOfWeek));
Options = new EnumSelection<AdditionalOptions>(AdditionalOptions.None, true, AdditionalOptions.None);
}
public EnumSelection<StartTask> StartUp { get; private set; }
public EnumSelection<DayOfWeek> Days { get; private set; }
public EnumSelection<AdditionalOptions> Options { get; private set; }
}
And here's how easy it is to bind checkboxes and radio buttons with this class:
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal">
<!-- Using RadioButtons for exactly 1 selection behavior -->
<RadioButton IsChecked="{Binding StartUp[Manual]}">Manual</RadioButton>
<RadioButton IsChecked="{Binding StartUp[Automatic]}">Automatic</RadioButton>
</StackPanel>
<StackPanel Orientation="Horizontal">
<!-- Using CheckBoxes for 0 or Many selection behavior -->
<CheckBox IsChecked="{Binding Days[Sunday]}">Sunday</CheckBox>
<CheckBox IsChecked="{Binding Days[Monday]}">Monday</CheckBox>
<CheckBox IsChecked="{Binding Days[Tuesday]}">Tuesday</CheckBox>
<CheckBox IsChecked="{Binding Days[Wednesday]}">Wednesday</CheckBox>
<CheckBox IsChecked="{Binding Days[Thursday]}">Thursday</CheckBox>
<CheckBox IsChecked="{Binding Days[Friday]}">Friday</CheckBox>
<CheckBox IsChecked="{Binding Days[Saturday]}">Saturday</CheckBox>
</StackPanel>
<StackPanel Orientation="Horizontal">
<!-- Using CheckBoxes for 0 or 1 selection behavior -->
<CheckBox IsChecked="{Binding Options[OptionA]}">Option A</CheckBox>
<CheckBox IsChecked="{Binding Options[OptionB]}">Option B</CheckBox>
</StackPanel>
</StackPanel>
i have a similar problem. for correct formatting EditText text content to double value i use this code:
try {
String eAm = etAmount.getText().toString();
DecimalFormat dF = new DecimalFormat("0.00");
Number num = dF.parse(eAm);
mPayContext.amount = num.doubleValue();
} catch (Exception e) {
mPayContext.amount = 0.0d;
}
this is independet from current phone locale and return correct double value.
hope it's help;
This isn't the most efficient, since you still cycle all the elements, but I thought it might be worth considering the very simple:
let keepGoing = true;
things.forEach( (thing) => {
if (noMore) keepGoing = false;
if (keepGoing) {
// do things with thing
}
});
CTRL - ML toggles line numbers in the CodeMirror area. See the QuickHelp for other keyboard shortcuts.
In more details CTRL - M (or ESC) bring you to command mode, then pressing the L keys should toggle the visibility of current cell line numbers. In more recent notebook versions Shift-L should toggle for all cells.
If you can't remember the shortcut, bring up the command palette Ctrl-Shift+P (Cmd+Shift+P on Mac), and search for "line numbers"), it should allow to toggle and show you the shortcut.
in my case all works fine. See in logcat. Maybe logcat show something that can help you to resolve your problem
Anyway you can try do it programmatically:
public class ActivityName extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// remove title
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
Run this command line on your preferred shell session:
db2 "select tabname from syscat.tables where owner = 'DB2INST1'"
Maybe you'd like to modify the owner name, and need to check the list of current owners?
db2 "select distinct owner from syscat.tables"
If you are trying this on a latest Mac OS X Mavericks, command line tools come with the Xcode 5.x
So make sure you have installed & updated Xcode to latest
after which make sure Xcode command line tools is pointed correctly using this command
xcode-select -p
Which might show some path like
/Applications/Xcode.app/Contents/Developer
Change the path to correct path using the switch command:
sudo xcode-select --switch /Library/Developer/CommandLineTools/
this should help you set it to correct path, after which you can use the same above command -p to check if it is set correctly
However this answer is simple, infact very simple and yea many have mentioned it that simply put the id of image into the following link https://drive.google.com/uc?export=view&id={fileId}
But however easy that is, I made a script to run in the console. Feed in an array of complete sharable links from google drive and get them converted into the above link. Then they can be simply used as static addresses.
array = ['https://drive.google.com/open?id=0B8kNn6zsgGEtUE5FaGNtcEthNWc','https://drive.google.com/open?id=0B8kNn6zsgGEtM2traVppYkhsV2s','https://drive.google.com/open?id=0B8kNn6zsgGEtNHgzT2x0MThJUlE']_x000D_
_x000D_
function separateDriveImageId(arr) {_x000D_
for (n=0;n<arr.length;n++){_x000D_
_x000D_
str = arr[n]_x000D_
_x000D_
for(i=0;i<str.length;i++){_x000D_
if( str.charAt(i)== '=' ){_x000D_
var num = i+1;_x000D_
var extrctdStrng = str.substr(num)_x000D_
_x000D_
}_x000D_
}_x000D_
console.log('https://drive.google.com/uc?export=view&id='+extrctdStrng)_x000D_
window.open('https://drive.google.com/uc?export=view&id='+extrctdStrng,'_blank')_x000D_
}_x000D_
_x000D_
_x000D_
}_x000D_
separateDriveImageId(array)
_x000D_
Another suggestion, which was the solution for me: I got the error in the line
<resources xmlns:ns1="http://schemas.android.com/tools" xmlns:ns2="urn:oasis:names:tc:xliff:document:1.2">
in the values.xml file that was automatically generated during the build process.
It was solved by adding the android
prefix in the styles.xml file.
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="textColorPrimary">@color/textColorPrimary</item>
<item name="colorBackground">@color/colorPrimaryDark</item>
</style>
had to be changed to
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="android:textColorPrimary">@color/textColorPrimary</item>
<item name="android:colorBackground">@color/colorPrimaryDark</item>
</style>
Alternatively you can do it in one line (tested in win10)
sqlite3 -help
sqlite3 -header -csv db.sqlite 'select * from tbl1;' > test.csv
Bonus: Using powershell with cmdlet and pipe (|).
get-content query.sql | sqlite3 -header -csv db.sqlite > test.csv
where query.sql is a file containing your SQL query
I you are using jQuery you can put the checkboxes in a form and then use something like this:
var formData = jQuery("#" + formId).serialize();
$.ajax({
type: "POST",
url: url,
data: formData,
success: success
});
@Query("SELECT rd FROM ReleaseDateType rd, CacheMedia cm WHERE ...")
I would simply change a column name to the dataset with the new name I want with the following code: names(dataset)[index_value] <- "new_col_name"
If I understand the situation correctly, you are just passing json data through the http body, instead of application/x-www-form-urlencoded
data.
You can fetch this data with this snippet:
$request_body = file_get_contents('php://input');
If you are passing json, then you can do:
$data = json_decode($request_body);
$data
then contains the json data is php array.
php://input
is a so called wrapper.
php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".
If you want to select only certain values from a single table you can try this
select distinct(*) from table_name where table_field in (1,1,2,3,4,5)
eg:
select first_name,phone_number from telephone_list where district id in (1,2,5,7,8,9)
if you want to select from multiple tables then you must go for UNION
.
If you just want to select the values 1, 1, 1, 2, 5, 1, 6 then you must do this
select 1
union select 1
union select 1
union select 2
union select 5
union select 1
union select 6
I had a similar problem, looking for grep/pattern regex and the "matched pattern found" as output.
At the end I used egrep (same regex on grep -e or -G didn't give me the same result of egrep) with the option -o
so, I think that could be something similar to (I'm NOT a regex Master) :
egrep -o "the*|this{1}|thoroughly{1}" filename
This might be extremely obvious for some, but I did understand this from the other answers.
Making a .gitignore file in a directory does nothing by itself. You have to open the .gitignore as a text file and write the files/directories you want it to ignore, each on its own line.
so cd to the Git repository directory
touch .gitignore
nano .gitignore
and then write the names of the files and or directories that you want to be ignored and their extensions if relevant.
Also, .gitignore is a hidden file on some OS (Macs for example) so you need ls -a
to see it, not just ls.
I have noticed also that even if you specify your website under secion - Website With Facebook Login -> Site url as e.g. http://example.com, but if your App Domains section is empty, and you open website as www.example.com you will get this error, too. To avoid it in "App Domains" section write example.com, that will allow subdomains, like www.example.com, something.example.com etc
Entity Framework does have some issues around identity fields.
You can't add GUID identity on existing table
Migrations: does not detect changes to DatabaseGeneratedOption
None of these describes your issue exactly and the Down() method in your extra migration is interesting because it appears to be attempting to remove IDENTITY from the column when your CREATE TABLE in the initial migration appears to set it!
Furthermore, if you use Update-Database -Script
or Update-Database -Verbose
to view the sql that is run from these AlterColumn
methods you will see that the sql is identical in Up
and Down
, and actually does nothing. IDENTITY remains unchanged (for the current version - EF 6.0.2 and below) - as described in the first 2 issues I linked to.
I think you should delete the redundant code in your extra migration and live with an empty migration for now. And you could subscribe to/vote for the issues to be addressed.
References:
You can use this code to get the desired result. It will remove duplicates.
$a1=array("a"=>"red","b"=>"green","c"=>"blue","d"=>"yellow");
$a2=array("e"=>"red","f"=>"green","g"=>"blue");
$result=array_unique(array_merge($a1,$a2));
print_r($result);
As we recently posted on the React blog, in the vast majority of cases you don't need getDerivedStateFromProps
at all.
If you just want to compute some derived data, either:
render
memoize-one
.Here's the simplest "after" example:
import memoize from "memoize-one";
class ExampleComponent extends React.Component {
getDerivedData = memoize(computeDerivedState);
render() {
const derivedData = this.getDerivedData(this.props.someValue);
// ...
}
}
Check out this section of the blog post to learn more.
A POSIX compliant one using the s
command:
sed '/CLIENTSCRIPT="foo"/s/.*/&\
CLIENTSCRIPT2="hello"/' file
int main()
{
char buff[1024] = {0};
FILE* cvt;
int status;
/* Launch converter and open a pipe through which the parent will write to it */
cvt = popen("converter", "w");
if (!cvt)
{
printf("couldn't open a pipe; quitting\n");
exit(1)
}
printf("enter Fahrenheit degrees: " );
fgets(buff, sizeof (buff), stdin); /*read user's input */
/* Send expression to converter for evaluation */
fprintf(cvt, "%s\n", buff);
fflush(cvt);
/* Close pipe to converter and wait for it to exit */
status=pclose(cvt);
/* Check the exit status of pclose() */
if (!WIFEXITED(status))
printf("error on closing the pipe\n");
return 0;
}
The important steps in this program are:
popen()
call which establishes the association between a child process and a pipe in the parent.fprintf()
call that uses the pipe as an ordinary file to write to the child process's stdin or read from its stdout.pclose()
call that closes the pipe and causes the child process to terminate.Ive been looking for an nice select dropdown for some time now and I found a good one. So im just gonna leave it here. Its called bootsrap-select
here's the link. check it out. it has editable dropdowns, combo drop downs and more. And its a breeze to add to your project.
If the link dies just search for bootstrap-select by silviomoreto.github.io. This is better because its a normal select tag
In this question:
1.Casting double to integer is very easy task.
2.But it's not rounding double value to the nearest decimal. Therefore casting can be done like this:
double d=99.99999999;
int i=(int)d;
System.out.println(i);
and it will print 99
, but rounding hasn't been done.
Thus for rounding we can use,
double d=99.99999999;
System.out.println( Math.round(d));
This will print the output of 100
.
Alternatively, if your objective is to output directly to a file or stdout, you can use cat
:
cat(s1, s2, sep=", ")
Follow this step to re install node modules and update them
works even if node_modules folder does not exist. now execute the following command synchronously. you can also use "npm update" but I think this'd preferred way
npm outdated // not necessary to run this command, but this will show outdated dependencies
npm install -g npm-check-updates // to install the "ncu" package
ncu -u --packageFile=package.json // to update dependencies version in package.json...don't run this command if you don't need to update the version
npm install: will install dependencies in your package.json file.
if you're okay with the version of your dependencies in your package.json file, no need to follow those steps just run
npm install
You can change the tabs by ctrl-pgup and ctrl-pgdown. On that tab you came from the NERDTree is still selected and you can open another tab.
lsof -t -i tcp:8000 | xargs kill -9
function chgAction( action_name )
{
if( action_name=="aaa" ) {
document.search-theme-form.action = "/AAA";
}
else if( action_name=="bbb" ) {
document.search-theme-form.action = "/BBB";
}
else if( action_name=="ccc" ) {
document.search-theme-form.action = "/CCC";
}
}
And your form needs to have name
in this case:
<form action="/" accept-charset="UTF-8" method="post" name="search-theme-form" id="search-theme-form">

Somehow python 3 came back (after some updates?) and is causing big issues with apt updates, so I've decided to remove python 3 completely from the alternatives:
root:~# python -V
Python 3.5.2
root:~# update-alternatives --config python
There are 2 choices for the alternative python (providing /usr/bin/python).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/python3.5 3 auto mode
1 /usr/bin/python2.7 2 manual mode
2 /usr/bin/python3.5 3 manual mode
root:~# update-alternatives --remove python /usr/bin/python3.5
root:~# update-alternatives --config python
There is 1 choice for the alternative python (providing /usr/bin/python).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/bin/python2.7 2 auto mode
* 1 /usr/bin/python2.7 2 manual mode
Press <enter> to keep the current choice[*], or type selection number: 0
root:~# python -V
Python 2.7.12
root:~# update-alternatives --config python
There is only one alternative in link group python (providing /usr/bin/python): /usr/bin/python2.7
Nothing to configure.
Motivation: You want to print prettify JSON response after curl command request.
Solution: json_pp - commandline tool that converts between some input and output formats (one of them is JSON). This program was copied from json_xs and modified. The default input format is json and the default output format is json with pretty option.
Synposis:
json_pp [-v] [-f from_format] [-t to_format] [-json_opt options_to_json1[,options_to_json2[,...]]]
Formula: <someCommand> | json_pp
Example:
Request
curl -X https://jsonplaceholder.typicode.com/todos/1 | json_pp
Response
{
"completed" : false,
"id" : 1,
"title" : "delectus aut autem",
"userId" : 1
}
You can use %s
or .format
:
>>> "%s" % 10
'10'
>>>
Or:
>>> '{}'.format(10)
'10'
>>>
As mentioned in this Jakob Nielsen article, drop down lists should be avoided for data that is well known to the user:
Menus of data well known to users, such as the month and year of their birth. Such information is often hardwired into users' fingers, and having to select such options from a menu breaks the standard paradigm for entering information and can even create more work for users.
The ideal solution is likely something like follows:
EDIT: Here is how we implemented our DOB picker: Masked text input field with HTML5 regex to force the numeric keyboard on iOS devices.
Somewhat cleaner solution than the accepted answer (based on this question):
public static boolean isAppInstalled(Context context, String packageName) {
try {
context.getPackageManager().getApplicationInfo(packageName, 0);
return true;
}
catch (PackageManager.NameNotFoundException e) {
return false;
}
}
I chose to put it in a helper class as a static utility. Usage example:
boolean whatsappFound = AndroidUtils.isAppInstalled(context, "com.whatsapp");
This answer shows how to get the app from the Play Store if the app is missing, though care needs to be taken on devices that don't have the Play Store.
I believe you are all wrong. you need to do:
array = array[]
in order to define it, and then:
array.append ["hello"]
to add to it.
Alternatively you could update brew
by installing it again. (Think I did this as El Capitan changed something)
Note: this is a heavy handed approach that will remove all applications installed via brew!
Try to install brew a fresh and it will tell how to uninstall.
At original time of writing to uninstall:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Edit: As of 2020 to uninstall:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

I got it fixed by running "C:\Program Files\Android\android-sdk\AVD Manager.exe" and repairing my broken device.
being a long time C++ developer (Rookie to web development :)), when I first came across this situation, I did the parameter assignment in the function definition, like it is mentioned in the question, as follows.
function myfunc(a,b=10)
But beware that it doesn't work consistently across browsers. For me it worked on chrome on my desktop, but did not work on chrome on android. Safer option, as many have mentioned above is -
function myfunc(a,b)
{
if (typeof(b)==='undefined') b = 10;
......
}
Intention for this answer is not to repeat the same solutions, what others have already mentioned, but to inform that parameter assignment in the function definition may work on some browsers, but don't rely on it.
<script type="text/Javascript">

inputVal.value = inputVal.value.substring(0, inputVal.value.length - 1);
}
}

One advantage of FTP is that there is a standard way to list files using dir
or ls
. Because of this, ftp plays nice with tools such as rsync. Granted, rsync
is usually done over ssh
, but the option is there.
The @RequestBody
javadoc states
Annotation indicating a method parameter should be bound to the body of the web request.
It uses registered instances of HttpMessageConverter
to deserialize the request body into an object of the annotated parameter type.
And the @RequestParam
javadoc states
Annotation which indicates that a method parameter should be bound to a web request parameter.
Spring binds the body of the request to the parameter annotated with @RequestBody
.
Spring binds request parameters from the request body (url-encoded parameters) to your method parameter. Spring will use the name of the parameter, ie. name
, to map the parameter.
Parameters are resolved in order. The @RequestBody
is processed first. Spring will consume all the HttpServletRequest
InputStream
. When it then tries to resolve the @RequestParam
, which is by default required
, there is no request parameter in the query string or what remains of the request body, ie. nothing. So it fails with 400 because the request can't be correctly handled by the handler method.
The handler for @RequestParam
acts first, reading what it can of the HttpServletRequest
InputStream
to map the request parameter, ie. the whole query string/url-encoded parameters. It does so and gets the value abc
mapped to the parameter name
. When the handler for @RequestBody
runs, there's nothing left in the request body, so the argument used is the empty string.
The handler for @RequestBody
reads the body and binds it to the parameter. The handler for @RequestParam
can then get the request parameter from the URL query string.
The handler for @RequestParam
reads from both the body and the URL query String. It would usually put them in a Map
, but since the parameter is of type String
, Spring will serialize the Map
as comma separated values. The handler for @RequestBody
then, again, has nothing left to read from the body.
Use this for datetimepicker, it works fine
$('#Date').data("DateTimePicker").hide();
There are two ways for writing a proper media queries in css. If you are writing media queries for larger device first, then the correct way of writing will be:
@media only screen
and (min-width : 415px){
/* Styles */
}
@media only screen
and (min-width : 769px){
/* Styles */
}
@media only screen
and (min-width : 992px){
/* Styles */
}
But if you are writing media queries for smaller device first, then it would be something like:
@media only screen
and (max-width : 991px){
/* Styles */
}
@media only screen
and (max-width : 768px){
/* Styles */
}
@media only screen
and (max-width : 414px){
/* Styles */
}
Select all the data and use the option "Text to Columns", that will allow your data for Applying Number Formatting ERIK
I've noticed that I forgot the "slash" in the beginning of the Route as below and I was getting same error :
Wrong :
app.get('api/courses', (req, res) => { ... }
)
Correct :
app.get('/api/courses', (req, res) => { ... }
)
As a more general answer, try using the hasPrefix method. For example, the code below checks to see if a string begins with 10, which is the error code used to identify a certain problem.
NSString* myString = @"10:Username taken";
if([myString hasPrefix:@"10"]) {
//display more elegant error message
}
I found out that the URL of the application conflicted with a module in the Sun GlassFish.
So, in the file sun-web.xml
I renamed the <context-root>/servlets-samples</context-root>.
It is now working.
Short definition:
grep
: search for specific terms in a file
#usage
$ grep This file.txt
Every line containing "This"
Every line containing "This"
Every line containing "This"
Every line containing "This"
$ cat file.txt
Every line containing "This"
Every line containing "This"
Every line containing "That"
Every line containing "This"
Every line containing "This"
Now awk
and sed
are completly different than grep
.
awk
and sed
are text processors. Not only do they have the ability to find what you are looking for in text, they have the ability to remove, add and modify the text as well (and much more).
awk
is mostly used for data extraction and reporting. sed
is a stream editor
Each one of them has its own functionality and specialties.
Example
Sed
$ sed -i 's/cat/dog/' file.txt
# this will replace any occurrence of the characters 'cat' by 'dog'
Awk
$ awk '{print $2}' file.txt
# this will print the second column of file.txt
Basic awk
usage:
Compute sum/average/max/min/etc. what ever you may need.
$ cat file.txt
A 10
B 20
C 60
$ awk 'BEGIN {sum=0; count=0; OFS="\t"} {sum+=$2; count++} END {print "Average:", sum/count}' file.txt
Average: 30
I recommend that you read this book: Sed & Awk: 2nd Ed.
It will help you become a proficient sed/awk user on any unix-like environment.

Just wanted to add that when using numbers for values with the css method you have to add them outside the apostrophe and then add the CSS unit in apostrophes.
$('.block').css('width',50 + '%');
or
var $block = $('.block')
$block.css({ 'width': 50 + '%', 'height': 4 + 'em', 'background': '#FFDAB9' });
puts
adds a new line to the end of each argument if there is not one already.
print
does not add a new line.
For example:
puts [[1,2,3], [4,5,nil]]
Would return:
1 2 3 4 5
Whereas print [[1,2,3], [4,5,nil]]
would return:
[[1,2,3], [4,5,nil]]
Notice how puts does not output the nil value whereas print does.
The curl installed by default in Debian supports HTTPS since a great while back. (a long time ago there were two separate packages, one with and one without SSL but that's not the case anymore)
You can send an OPTIONS request with curl like this:
curl -i -X OPTIONS http://example.org/path
You may also use -v
instead of -i
to see more output.
To send a plain * (instead of the path, see RFC 7231) with the OPTIONS method, you need curl 7.55.0 or later as then you can run a command line like:
curl -i --request-target "*" -X OPTIONS http://example.org
Basically there are two ways: query DB (data length + index length) or check files size. Index length is related to data stored in indexes.
Everything is described here:
http://www.mkyong.com/mysql/how-to-calculate-the-mysql-database-size/
let bytes = 1024 * 10 * 10 * 10;
console.log(getReadableFileSizeString(bytes))
will return 1000.0?? instead of 1MB
As for today, answers of @knowbody (https://stackoverflow.com/a/42418963/6778546) and @Rocket Hazmat (https://stackoverflow.com/a/8837511/6778546) can be combined to provide for ES2015 support and correct date handling:
arr.sort((a, b) => {
const dateA = new Date(a.updated_at);
const dateB = new Date(b.updated_at);
return dateA - dateB;
});
Yes, you can use filter if you know at which position in the tuple the desired column resides. If the case is that the id is the first element of the tuple then you can filter the list like so:
filter(lambda t: t[0]==10, mylist)
This will return the list of corresponding tuples. If you want the age, just pick the element you want. Instead of filter you could also use list comprehension and pick the element in the first go. You could even unpack it right away (if there is only one result):
[age] = [t[1] for t in mylist if t[0]==10]
But I would strongly recommend to use dictionaries or named tuples for this purpose.
Firstly It tries insert. If there is a conflict on url
column then it updates content and last_analyzed fields. If updates are rare this might be better option.
INSERT INTO URLs (url, content, last_analyzed)
VALUES
(
%(url)s,
%(content)s,
NOW()
)
ON CONFLICT (url)
DO
UPDATE
SET content=%(content)s, last_analyzed = NOW();
I used the node net module to open a socket to the webservice.
/* on Login request */
socket.on('login', function(credentials /* {username} {password} */){
if( !_this.netConnected ){
_this.net.connect(8081, '127.0.0.1', function() {
logger.gps('('+socket.id + ') '+credentials.username+' connected to: 127.0.0.1:8081');
_this.netConnected = true;
_this.username = credentials.username;
_this.password = credentials.password;
_this.m_RequestId = 1;
/* make SOAP Login request */
soapGps('', _this, 'login', credentials.username);
});
} else {
/* make SOAP Login request */
_this.m_RequestId = _this.m_RequestId +1;
soapGps('', _this, 'login', credentials.username);
}
});
Send soap requests
/* SOAP request func */
module.exports = function soapGps(xmlResponse, client, header, data) {
/* send Login request */
if(header == 'login'){
var SOAP_Headers = "POST /soap/gps/login HTTP/1.1\r\nHost: soap.example.com\r\nUser-Agent: SOAP-client/SecurityCenter3.0\r\n" +
"Content-Type: application/soap+xml; charset=\"utf-8\"";
var SOAP_Envelope= "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" +
"<env:Envelope xmlns:env=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:SOAP-ENC=\"http://www.w3.org/2003/05/soap-encoding\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:n=\"http://www.example.com\"><env:Header><n:Request>" +
"Login" +

client.net.write(SOAP_Headers + "\r\nContent-Length:" + SOAP_Envelope.length.toString() + "\r\n\r\n");
client.net.write(SOAP_Envelope);
return;
}
Parse soap response, i used module - xml2js
var parser = new xml2js.Parser({
normalize: true,
trim: true,
explicitArray: false
});
//client.net.setEncoding('utf8');
client.net.on('data', function(response) {
parser.parseString(response);
});
parser.addListener('end', function( xmlResponse ) {
var response = xmlResponse['env:Envelope']['env:Header']['n:Response']._;
/* handle Login response */
if (response == 'Login'){
/* make SOAP LoginContinue request */
soapGps(xmlResponse, client, '');
}
/* handle LoginContinue response */
if (response == 'LoginContinue') {
if(xmlResponse['env:Envelope']['env:Body']['n:ResponseLoginContinue']['n:ErrCode'] == "ok") {
var nTimeMsecServer = xmlResponse['env:Envelope']['env:Body']['n:ResponseLoginContinue']['n:CurrentTime'];
var nTimeMsecOur = new Date().getTime();
} else {
/* Unsuccessful login */
io.to(client.id).emit('Error', "invalid login");
client.net.destroy();
}
}
});

RTSP (actually RTP) can be used for streaming video, but also many other types of media including live presentations. Rtsp is just the protocol used to setup the RTP session.
For all the details you can check out my open source RTSP Server implementation on the following address: https://net7mma.codeplex.com/
Or my article @ http://www.codeproject.com/Articles/507218/Managed-Media-Aggregation-using-Rtsp-and-Rtp
It supports re-sourcing streams as well as the dynamic creation of streams, various RFC's are implemented and the library achieves better performance and less memory then FFMPEG and just about any other solutions in the transport layer and thus makes it a good candidate to use as a centralized point of access for most scenarios.
Looks like you called it 'ant build..xml'. ant automatically choose a file build.xml in the current directory, so it is enough to call 'ant' (if a default-target is defined) or 'ant target' (the target named target will be called).
With the call 'ant -p' you get a list of targets defined in your build.xml.
Edit: In the comment is shown the call 'ant -verbose build.xml'. To be correct, this has to be called as 'ant -verbose'. The file build.xml in the current directory will be used automatically. If it is needed to explicitly specify the buildfile (because it's name isn't build.xml for example), you have to specify the buildfile with the '-f'-option: 'ant -verbose -f build.xml'. I hope this helps.
It is not quite clear what function you are talking about and if you need 2 separate branches or one. Assuming one:
Change your first line to
$slide = '';
if (isset($_GET["id"]))
{
$slide = $_GET["id"];
}
Although there are some useful algorithmic explanations here, I think it may help to add some simple 'real life' reasoning as to why it works this way, which I have found useful when introducing the subject to young newcomers:
With something like 'range(1,10)' confusion can arise from thinking that pair of parameters represents the "start and end".
It is actually start and "stop".
Now, if it were the "end" value then, yes, you might expect that number would be included as the final entry in the sequence. But it is not the "end".
Others mistakenly call that parameter "count" because if you only ever use 'range(n)' then it does, of course, iterate 'n' times. This logic breaks down when you add the start parameter.
So the key point is to remember its name: "stop". That means it is the point at which, when reached, iteration will stop immediately. Not after that point.
So, while "start" does indeed represent the first value to be included, on reaching the "stop" value it 'breaks' rather than continuing to process 'that one as well' before stopping.
One analogy that I have used in explaining this to kids is that, ironically, it is better behaved than kids! It doesn't stop after it supposed to - it stops immediately without finishing what it was doing. (They get this ;) )
Another analogy - when you drive a car you don't pass a stop/yield/'give way' sign and end up with it sitting somewhere next to, or behind, your car. Technically you still haven't reached it when you do stop. It is not included in the 'things you passed on your journey'.
I hope some of that helps in explaining to Pythonitos/Pythonitas!
One other approach that we have taken successfully is to generate the WS client proxy code using wsimport (from Ant, as an Ant task) and specify the wsdlLocation attribute.
<wsimport debug="true" keep="true" verbose="false" target="2.1" sourcedestdir="${generated.client}" wsdl="${src}${wsdl.file}" wsdlLocation="${wsdl.file}">
</wsimport>
Since we run this for a project w/ multiple WSDLs, the script resolves the $(wsdl.file} value dynamically which is set up to be /META-INF/wsdl/YourWebServiceName.wsdl relative to the JavaSource location (or /src, depending on how you have your project set up). During the build proess, the WSDL and XSDs files are copied to this location and packaged in the JAR file. (similar to the solution described by Bhasakar above)
MyApp.jar
|__META-INF
|__wsdl
|__YourWebServiceName.wsdl
|__YourWebServiceName_schema1.xsd
|__YourWebServiceName_schmea2.xsd
Note: make sure the WSDL files are using relative refrerences to any imported XSDs and not http URLs:
<types>
<xsd:schema>
<xsd:import namespace="http://valueobject.common.services.xyz.com/" schemaLocation="YourWebService_schema1.xsd"/>
</xsd:schema>
<xsd:schema>
<xsd:import namespace="http://exceptions.util.xyz.com/" schemaLocation="YourWebService_schema2.xsd"/>
</xsd:schema>
</types>
In the generated code, we find this:
/**
* This class was generated by the JAX-WS RI.
* JAX-WS RI 2.2-b05-
* Generated source version: 2.1
*
*/
@WebServiceClient(name = "YourService", targetNamespace = "http://test.webservice.services.xyz.com/", wsdlLocation = "/META-INF/wsdl/YourService.wsdl")
public class YourService_Service
extends Service
{
private final static URL YOURWEBSERVICE_WSDL_LOCATION;
private final static WebServiceException YOURWEBSERVICE_EXCEPTION;
private final static QName YOURWEBSERVICE_QNAME = new QName("http://test.webservice.services.xyz.com/", "YourService");
static {
YOURWEBSERVICE_WSDL_LOCATION = com.xyz.services.webservice.test.YourService_Service.class.getResource("/META-INF/wsdl/YourService.wsdl");
WebServiceException e = null;
if (YOURWEBSERVICE_WSDL_LOCATION == null) {
e = new WebServiceException("Cannot find '/META-INF/wsdl/YourService.wsdl' wsdl. Place the resource correctly in the classpath.");
}
YOURWEBSERVICE_EXCEPTION = e;
}
public YourService_Service() {
super(__getWsdlLocation(), YOURWEBSERVICE_QNAME);
}
public YourService_Service(URL wsdlLocation, QName serviceName) {
super(wsdlLocation, serviceName);
}
/**
*
* @return
* returns YourService
*/
@WebEndpoint(name = "YourServicePort")
public YourService getYourServicePort() {
return super.getPort(new QName("http://test.webservice.services.xyz.com/", "YourServicePort"), YourService.class);
}
/**
*
* @param features
* A list of {@link javax.xml.ws.WebServiceFeature} to configure on the proxy. Supported features not in the <code>features</code> parameter will have their default values.
* @return

@WebEndpoint(name = "YourServicePort")
public YourService getYourServicePort(WebServiceFeature... features) {
return super.getPort(new QName("http://test.webservice.services.xyz.com/", "YourServicePort"), YourService.class, features);
}
private static URL __getWsdlLocation() {
if (YOURWEBSERVICE_EXCEPTION!= null) {
throw YOURWEBSERVICE_EXCEPTION;
}
return YOURWEBSERVICE_WSDL_LOCATION;
}
}
Perhaps this might help too. It's just a different approach that does not use the "catalog" approach.
If you have to make a lot of "id" lookups and it should be really fast you should use a second array containing all the "ids" as keys:
$lookup_array=array();
foreach($my_array as $arr){
$lookup_array[$arr['id']]=1;
}
Now you can check for an existing id very fast, for example:
echo (isset($lookup_array[152]))?'yes':'no';
inelegant (but effective) way: use percentages
#horizontal-style {
width: 100%;
}
li {
width: 20%;
}
This only works with the 5 <li>
example. For more or less, modify your percentage accordingly. If you have other <li>
s on your page, you can always assign these particular ones a class of "menu-li" so that only they are affected.

I kept having this problem because windows was setting my node_modules
folder to Readonly. Make sure you uncheck this.
Ensure that Enhanced session mode settings are enabled on the Hyper-V host.
Start Hyper-V Manager, and in the Actions section, select "Hyper-V Settings".
Make sure that enhanced session mode is allowed in the Server section. Then, make sure that the enhanced session mode is available in the User section.
Enable Hyper-V Guest Services for your virtual machine
Right-click on Virtual Machine > Settings. Select the Integration Services in the left-lower corner of the menu. Check Guest Service and click OK.
Start a virtual machine and click Show Options in the pop-up windows.
Or click "Edit Session Settings..." in the Actions panel on the right
It may only appear when you're (able to get) connected to it. If it doesn't appear try Starting and then Connecting to the VM while paying close attention to the panel in the Hyper-V Manager.
View local resources. Then, select the "More..." menu.
From there, you can choose which devices to share. Removable drives are especially useful for file sharing.
Choose to "Save my settings for future connections to this virtual machine".
Click Connect. Drive sharing is now complete, and you will see the shared drive in this PC > Network Locations section of Windows Explorer after using the enhanced session mode to sigh to the VM. You should now be able to copy files from a physical machine and paste them into a virtual machine, and vice versa.

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.
You can try this sample code:
main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" android:id="@+id/rootLayout">
<Button
android:id="@+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MOVE" android:layout_centerHorizontal="true"/>
<ImageView
android:id="@+id/img1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
<ImageView
android:id="@+id/img2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
<ImageView
android:id="@+id/img3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">
<ImageView
android:id="@+id/img4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
</LinearLayout>
</RelativeLayout>
Your activity
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
{
@Override
public void onClick(View v)
{
ImageView img = (ImageView) findViewById( R.id.img1 );
moveViewToScreenCenter( img );
img = (ImageView) findViewById( R.id.img2 );
moveViewToScreenCenter( img );
img = (ImageView) findViewById( R.id.img3 );
moveViewToScreenCenter( img );
img = (ImageView) findViewById( R.id.img4 );
moveViewToScreenCenter( img );
}
});
}
private void moveViewToScreenCenter( View view )
{
RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
DisplayMetrics dm = new DisplayMetrics();
this.getWindowManager().getDefaultDisplay().getMetrics( dm );
int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();
int originalPos[] = new int[2];
view.getLocationOnScreen( originalPos );
int xDest = dm.widthPixels/2;
xDest -= (view.getMeasuredWidth()/2);
int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;
TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
anim.setDuration(1000);
anim.setFillAfter( true );
view.startAnimation(anim);
}
The method moveViewToScreenCenter
gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset
variable measures the status bar height.
I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.
They are not null if you don't initialize the struct.
Snapshot s; // receives no initialization
Snapshot s = {}; // value initializes all members
The second will make all members zero, the first leaves them at unspecified values. Note that it is recursive:
struct Parent { Snapshot s; };
Parent p; // receives no initialization
Parent p = {}; // value initializes all members
The second will make p.s.{x,y}
zero. You cannot use these aggregate initializer lists if you've got constructors in your struct. If that is the case, you will have to add proper initalization to those constructors
struct Snapshot {
int x;
double y;
Snapshot():x(0),y(0) { }
// other ctors / functions...
};
Will initialize both x and y to 0. Note that you can use x(), y()
to initialize them disregarding of their type: That's then value initialization, and usually yields a proper initial value (0 for int, 0.0 for double, calling the default constructor for user defined types that have user declared constructors, ...). This is important especially if your struct is a template.
To add a header just add the following code to the location block where you want to add the header:
location some-location {
add_header X-my-header my-header-content;
}
Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.
It's better not to use refs in such cases. Use:
<input
type="checkbox"
checked={this.state.active}
onClick={this.handleClick}
/>
There are some options:
checked
vs defaultChecked
The former would respond to both state changes and clicks. The latter would ignore state changes.
onClick
vs onChange
The former would always trigger on clicks.
The latter would not trigger on clicks if checked
attribute is present on input
element.

varchar [ ( n | max ) ] Variable-length, non-Unicode character data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of data entered + 2 bytes. The data entered can be 0 characters in length. The ISO synonyms for varchar are char varying or character varying.
1 character = 1 byte. And don't forget 2 bytes for the termination. So, 2^31-3 characters.
OP here, I have learned a lot more about node since I first asked this question. Though Dmitry's answer was very helpful, what ultimately did it for me is to install node with the correct permissions.
I highly recommend not installing node using any package managers, but rather to compile it yourself so that it resides in a local directory with normal permissions.
This article provides a very clear step-by-step instruction of how to do so:
Employees.objects.values_list('eng_name', flat=True)
That creates a flat list of all eng_name
s. If you want more than one field per row, you can't do a flat list: this will create a list of tuples:
Employees.objects.values_list('eng_name', 'rank')
I think this is related, but I had a problem when building directly using msbuild
command line (from a batch file) vs building from within VS.
Using something like the following:
<PostBuildEvent>
MOVE /Y "$(TargetDir)something.file1" "$(ProjectDir)something.file1"
start XCOPY /Y /R "$(SolutionDir)SomeConsoleApp\bin\$(ConfigurationName)\*" "$(ProjectDir)App_Data\Consoles\SomeConsoleApp\"
</PostBuildEvent>
(note: start XCOPY
rather than XCOPY
used to get around a permissions issue which prevented copying)
The macro $(SolutionDir)
evaluated to ..\
when executing msbuild from a batchfile, which resulted in the XCOPY
command failing. It otherwise worked fine when built from within Visual Studio. Confirmed using /verbosity:diagnostic
to see the evaluated output.
Using the macro $(ProjectDir)..\
instead, which amounts to the same thing, worked fine and retained the full path in both build scenarios.
If each file only has one sequence of aminoacids, I wouldn't use regular expressions at all. Just something like this:
def read_amino_acid_sequence(path):
with open(path) as sequence_file:
title = sequence_file.readline() # read 1st line
aminoacid_sequence = sequence_file.read() # read the rest
# some cleanup, if necessary
title = title.strip() # remove trailing white spaces and newline
aminoacid_sequence = aminoacid_sequence.replace(" ","").replace("\n","")
return title, aminoacid_sequence
select sum(qty), name
from (
select count(m.owner_id) as qty, o.name
from transport t,owner o,motorbike m
where t.type='motobike' and o.owner_id=m.owner_id

group by m.owner_id
union all

If you're already using JavaScript to center stuff when the screen is too small (as per your comment for your header), why not just undo floats/margins with JavaScript while you're at it and use floats and margins normally.
You could even use CSS media queries to reduce the amount JavaScript you're using.
names = ["tim", "tom", "bob", "alex"]
sql_string = names.map { |t| "name = '#{t}'" }.join(" OR ")

I find that no one mentions this difference:
__getattribute__
has a default implementation, but __getattr__
does not.
class A:
pass
a = A()
a.__getattr__ # error
a.__getattribute__ # return a method-wrapper
This has a clear meaning: since __getattribute__
has a default implementation, while __getattr__
not, clearly python encourages users to implement __getattr__
.
This is a runnable example.

A link to that page is posted at the very bottom of this page: https://developers.google.com/recaptcha/intro
One issue I came up with that prevented these two files from working correctly was with my php.ini file for the website. Make sure this property is setup properly, as follows: allow_url_fopen = On
\begin{equation}
\resizebox{.9\hsize}{!}{$A+B+C+D+E+F+G+H+I+J+K+L+M+N+O+P+Q+R+S+T+U+V+W+X+Y+Z$}
\end{equation}
or
\begin{equation}
\resizebox{.8\hsize}{!}{$A+B+C+D+E+F+G+H+I+J+K+L+M+N+O+P+Q+R+S+T+U+V+W+X+Y+Z$}
\end{equation}
<xsl:value-of select="name(.)" /> : <xsl:value-of select="."/>
just use this.

double percent= (double)(fxd*40)/100;
One extra feature is you can also use-media queries in the media attribute of the <link>
tag.
<link href="style.css" rel="stylesheet">
<link href="justForFrint.css" rel="stylesheet" media="print">
<link href="deviceSizeDepending.css" rel="stylesheet" media="(min-width: 40em)">
With this, the browser will download all CSS resources, regardless of the media attribute. The difference is that if the media-query of the media attribute is evaluated to false then that .css file and his content will not be render-blocking.
Therefore, it is recommended to use the media attribute in the <link>
tag since it guarantees a better user experience.
Here you can read a Google article about this issue https://developers.google.com/web/fundamentals/performance/critical-rendering-path/render-blocking-css
Some tools that will help you to automate the separation of your css code in different files according to your media-querys

You are facing issue in
s1.name="Paolo";
because, in the LHS, you're using an array type, which is not assignable.
To elaborate, from C11
, chapter §6.5.16
assignment operator shall have a modifiable lvalue as its left operand.
and, regarding the modifiable lvalue, from chapter §6.3.2.1
A modifiable lvalue is an lvalue that does not have array type, [...]
You need to use strcpy()
to copy into the array.
That said, data s1 = {"Paolo", "Rossi", 19};
works fine, because this is not a direct assignment involving assignment operator. There we're using a brace-enclosed initializer list to provide the initial values of the object. That follows the law of initialization, as mentioned in chapter §6.7.9
Each brace-enclosed initializer list has an associated current object. When no designations are present, subobjects of the current object are initialized in order according to the type of the current object: array elements in increasing subscript order, structure members in declaration order, and the first named member of a union.[....]
My solution works in all web browsers including Microsoft Internet Explorer and doesn't use any regular expression, it's inspired of Noah Cardoza and Martin Konecny solutions:
function getHostname(href) {
if (typeof URL === 'object') {
// workaround for MS IE 11 (Noah Cardoza's solution but without using Object.assign())
var dummyNode = document.createElement('a');
dummyNode.href = href;
return dummyNode.hostname;
} else {
// Martin Konecny's solution
return new URL(href).hostname;
}
}
In order to work on all modern browsers, you will need two steps:
Add javascript:void(0);
as src
attribute for the iframe element. Otherwise the content will be overriden by the empty src
on Firefox.
<iframe src="javascript:void(0);"></iframe>
Programatically change the content of the inner html
element.
$(iframeSelector).contents().find('html').html(htmlContent);
Step 1 from comment (link) by @susan
Step 2 from solutions (link1, link2) by @erimerturk and @x10
Mark, this is already answered in your previous topic. But OK, here it is again:
Suppose ${list}
points to a List<Object>
, then the following
<c:forEach items="${list}" var="item">
${item}<br>
</c:forEach>
does basically the same as as following in "normal Java":
for (Object item : list) {
System.out.println(item);
}
If you have a List<Map<K, V>>
instead, then the following
<c:forEach items="${list}" var="map">
<c:forEach items="${map}" var="entry">
${entry.key}<br>
${entry.value}<br>
</c:forEach>
</c:forEach>
does basically the same as as following in "normal Java":
for (Map<K, V> map : list) {
for (Entry<K, V> entry : map.entrySet()) {
System.out.println(entry.getKey());
System.out.println(entry.getValue());
}
}
The key
and value
are here not special methods or so. They are actually getter methods of Map.Entry
object (click at the blue Map.Entry
link to see the API doc). In EL (Expression Language) you can use the .
dot operator to access getter methods using "property name" (the getter method name without the get
prefix), all just according the Javabean specification.
That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".
Reading the documentation and studying what the fragment id is, it appears to simply be the stack index, so this works:
fragmentManager.popBackStackImmediate(0, FragmentManager.POP_BACK_STACK_INCLUSIVE);
Zero (0
) is the the bottom of the stack, so popping up to it inclusive clears the stack.
CAVEAT: Although the above works in my program, I hesitate a bit because the FragmentManager documentation never actually states that the id is the stack index. It makes sense that it would be, and all my debug logs bare out that it is, but perhaps in some special circumstance it would not? Can any one confirm this one way or the other? If it is, then the above is the best solution. If not, this is the alternative:
while(fragmentManager.getBackStackEntryCount() > 0) { fragmentManager.popBackStackImmediate(); }
Updating to use tibble()
You can pass a named vector of length greater than 1 to the by
argument of left_join()
:
library(dplyr)
d1 <- tibble(
x = letters[1:3],
y = LETTERS[1:3],
a = rnorm(3)
)
d2 <- tibble(
x2 = letters[3:1],
y2 = LETTERS[3:1],
b = rnorm(3)
)
left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))
Even using this won't work. I think the best solution is Browserify:
module.exports = {
func1: function () {
console.log("I am function 1");
},
func2: function () {
console.log("I am function 2");
}
};
-getFunc1.js-
var common = require('./common');
common.func1();
There is notable difference between const and readonly fields in C#.Net
const is by default static and needs to be initialized with constant value, which can not be modified later on. Change of value is not allowed in constructors, too. It can not be used with all datatypes. For ex- DateTime. It can not be used with DateTime datatype.
public const DateTime dt = DateTime.Today; //throws compilation error
public const string Name = string.Empty; //throws compilation error
public readonly string Name = string.Empty; //No error, legal
readonly can be declared as static, but not necessary. No need to initialize at the time of declaration. Its value can be assigned or changed using constructor. So, it gives advantage when used as instance class member. Two different instantiation may have different value of readonly field. For ex -
class A
{
public readonly int Id;
public A(int i)
{
Id = i;
}
}
Then readonly field can be initialised with instant specific values, as follows:
A objOne = new A(5);
A objTwo = new A(10);
Here, instance objOne will have value of readonly field as 5 and objTwo has 10. Which is not possible using const.
This is a a sensible point.
A null date is not a zero date. They may look the same, but they ain't. In mysql, a null date value is null. A zero date value is an empty string ('') and '0000-00-00 00:00:00'
On a null date "... where mydate = ''" will fail.
On an empty/zero date "... where mydate is null" will fail.
But now let's get funky. In mysql dates, empty/zero date are strictly the same.
by example
select if(myDate is null, 'null', myDate) as mydate from myTable where myDate = ''; select if(myDate is null, 'null', myDate) as mydate from myTable where myDate = '0000-00-00 00:00:00'
will BOTH output: '0000-00-00 00:00:00'. if you update myDate with '' or '0000-00-00 00:00:00', both selects will still work the same.
In php, the mysql null dates type will be respected with the standard mysql connector, and be real nulls ($var === null, is_null($var)). Empty dates will always be represented as '0000-00-00 00:00:00'.
I strongly advise to use only null dates, OR only empty dates if you can. (some systems will use "virual" zero dates which are valid Gregorian dates, like 1970-01-01 (linux) or 0001-01-01 (oracle).
empty dates are easier in php/mysql. You don't have the "where field is null" to handle. However, you have to "manually" transform the '0000-00-00 00:00:00' date in '' to display empty fields. (to store or search you don't have special case to handle for zero dates, which is nice).
Null dates need better care. you have to be careful when you insert or update to NOT add quotes around null, else a zero date will be inserted instead of null, which causes your standard data havoc. In search forms, you will need to handle cases like "and mydate is not null", and so on.
Null dates are usually more work. but they much MUCH MUCH faster than zero dates for queries.
Also, if you want to add module assets both CSS and JS, you can use the following logic. See how you need to indicate the correct path to getPathOfAlias:
public static function register($file)
{
$url = Yii::app()->getAssetManager()->publish(
Yii::getPathOfAlias('application.modules.shop.assets.css'));
$path = $url . '/' . $file;
if(strpos($file, 'js') !== false)
return Yii::app()->clientScript->registerScriptFile($path);
else if(strpos($file, 'css') !== false)
return Yii::app()->clientScript->registerCssFile($path);
return $path;
}
The above code has been taken from GPLed Yii based Webshop app.
package.json
counts with a optionalDependencies
key.
NPM on Optional Dependencies.
You can add fsevents
to this object and if you find yourself installing packages in a different platform than MacOS, fsevents
will be skipped by either yarn or npm.
"optionalDependencies": {
"fsevents": "2.1.2"
},
You will find a message like the following in the installation log:
info [email protected]: The platform "linux" is incompatible with this module.
info "[email protected]" is an optional dependency and failed compatibility check. Excluding it from installation.
info [email protected]: The platform "linux" is incompatible with this module.
info "[email protected]" is an optional dependency and failed compatibility check. Excluding it from installation.
Hope it helps!
Here's how to hook this up on any click (useful if your page is placing many AJAX calls and you're trying to navigate away).
$ ->
$.xhrPool = [];
$(document).ajaxSend (e, jqXHR, options) ->
$.xhrPool.push(jqXHR)
$(document).ajaxComplete (e, jqXHR, options) ->
$.xhrPool = $.grep($.xhrPool, (x) -> return x != jqXHR);
$(document).delegate 'a', 'click', ->
while (request = $.xhrPool.pop())
request.abort()
On the most part, I'd say follow the pattern. I have deviated from it, but very rarely, and for specific reasons. In the case in point, the biggest issue I'd have is that I'd probably still use an Action<SomeObjectType>
, allowing me to add extra properties later, and to use the occasional 2-way property (think Handled
, or other feedback-events where the subscriber needs to to set a property on the event object). And once you've started down that line, you might as well use EventHandler<T>
for some T
.
var object = { "a": 1, "b": 2};_x000D_
$.each(object, function(key, value){_x000D_
console.log(key + ": " + object[key]);_x000D_
});

As already said by Jordão, just negate it:
if (!(id in tutorTimes)) { ... }
Note: The above test if tutorTimes has a property with the name specified in id, anywhere in the prototype chain. For example "valueOf" in tutorTimes
returns true because it is defined in Object.prototype.
If you want to test if a property doesn't exist in the current object, use hasOwnProperty:
if (!tutorTimes.hasOwnProperty(id)) { ... }
Or if you might have a key that is hasOwnPropery you can use this:
if (!Object.prototype.hasOwnProperty.call(tutorTimes,id)) { ... }
Create a custom class, e.g. .custom-btn
. Note that to override jQM styles without using !important
, CSS hierarchy should be respected. .ui-btn.custom-class
or .ui-input-btn.custom-class
.
.ui-input-btn.custom-btn {
border:1px solid red;
text-decoration:none;
font-family:helvetica;
color:red;
background:url(img.png) repeat-x;
}
Add a data-wrapper-class
to input
. The custom class will be added to input
wrapping div.
<input type="button" data-wrapper-class="custom-btn">
Input
button is wrapped by a DIV with class ui-btn
. You need to select that div and the input[type="submit"]
. Using !important
is essential to override Jquery Mobile styles.
div.ui-btn, input[type="submit"] {
border:1px solid red !important;
text-decoration:none !important;
font-family:helvetica !important;
color:red !important;
background:url(../images/btn_hover.png) repeat-x !important;
}
This is my image upload solution, when user selected the file.
HTML part:
<form enctype="multipart/form-data" id="img_form" method="post">
<input id="img_input" type="file" name="image" accept="image/*">
</form>
JavaScript:
document.getElementById('img_input').onchange = function () {
upload();
};
function upload() {
var upload = document.getElementById('img_input');
var image = upload.files[0];
$.ajax({
url:"/foo/bar/uploadPic",
type: "POST",
data: new FormData($('#img_form')[0]),
contentType:false,
cache: false,
processData:false,
success:function (msg) {}
});
};
After looking through all the answers, I was surprised to see that no one mentioned the Glide API for handling images. Great library, and abstracts out all the complexity of bitmap management. You can load and resize images quickly with this library and a single line of code.
Glide.with(this).load(yourImageResource).into(imageview);
You can get the repository here: https://github.com/bumptech/glide
prop_cycle
color_cycle
was deprecated in 1.5 in favor of this generalization: http://matplotlib.org/users/whats_new.html#added-axes-prop-cycle-key-to-rcparams
# cycler is a separate package extracted from matplotlib.
from cycler import cycler
import matplotlib.pyplot as plt
plt.rc('axes', prop_cycle=(cycler('color', ['r', 'g', 'b'])))
plt.plot([1, 2])
plt.plot([2, 3])

Also shown in the (now badly named) example: http://matplotlib.org/1.5.1/examples/color/color_cycle_demo.html mentioned at: https://stackoverflow.com/a/4971431/895245
Tested in matplotlib 1.5.1.
You could do a
mysqlimport --columns='head -n 1 $yourfile' --ignore-lines=1 dbname $yourfile`
That is, if your file is comma separated and is not semi-colon separated. Else you might need to sed
through it too.

keyPressed - when the key goes down
keyReleased - when the key comes up
keyTyped - when the unicode character represented by this key is sent by the keyboard to system input.
I personally would use keyReleased for this. It will fire only when they lift their finger up.
Note that keyTyped will only work for something that can be printed (I don't know if F5 can or not) and I believe will fire over and over again if the key is held down. This would be useful for something like... moving a character across the screen or something.
One possible explanation is a database trigger that fires for each DROP TABLE
statement. To find the trigger, query the _TRIGGERS
dictionary views:
select * from all_triggers
where trigger_type in ('AFTER EVENT', 'BEFORE EVENT')
disable any suspicious trigger with
alter trigger <trigger_name> disable;
and try re-running your DROP TABLE
statement
What I did is create a separate content view as shown here.
The content view is freeform and can has all subviews added to it with their own constraints in relation to the contentView.
The UIScrollView is added to the main view controller.
Programatically I add the contentView which is linked via IBOutlet to class and set the contentView of UIScrollView.
You can use the options when initializing the carousel, like this:
// interval is in milliseconds. 1000 = 1 second -> so 1000 * 10 = 10 seconds
$('.carousel').carousel({
interval: 1000 * 10
});
or you can use the interval
attribute directly on the HTML
tag, like this:
<div class="carousel" data-interval="10000">
The advantage of the latter approach is that you do not have to write any JS for it - while the advantage of the former is that you can compute the interval and initialize it with a variable value at run time.
Cheap and nasty solution.. Use the ugly #! style.
To set it:
window.location.hash = '#!' + id;
To read it:
id = window.location.hash.replace(/^#!/, '');
Since it doesn't match and anchor or id in the page, it won't jump.
You can use less code, writing this:
$users = DB::table('really_long_table_name')
->get(array('really_long_table_name.field_very_long_name as short_name'));
And of course if you want to select more fields, just write a "," and add more:
$users = DB::table('really_long_table_name')
->get(array('really_long_table_name.field_very_long_name as short_name', 'really_long_table_name.another_field as other', 'and_another'));
This is very practical when you use a joins complex query
In addition to suggestions made by @Jim Cook. One other thought is to use a switch instead of if-elses:
while(rs.next()) {
int numColumns = rsmd.getColumnCount();
JSONObject obj = new JSONObject();
for( int i=1; i<numColumns+1; i++) {
String column_name = rsmd.getColumnName(i);
switch( rsmd.getColumnType( i ) ) {
case java.sql.Types.ARRAY:
obj.put(column_name, rs.getArray(column_name)); break;
case java.sql.Types.BIGINT:
obj.put(column_name, rs.getInt(column_name)); break;
case java.sql.Types.BOOLEAN:
obj.put(column_name, rs.getBoolean(column_name)); break;
case java.sql.Types.BLOB:
obj.put(column_name, rs.getBlob(column_name)); break;
case java.sql.Types.DOUBLE:
obj.put(column_name, rs.getDouble(column_name)); break;
case java.sql.Types.FLOAT:
obj.put(column_name, rs.getFloat(column_name)); break;
case java.sql.Types.INTEGER:
obj.put(column_name, rs.getInt(column_name)); break;
case java.sql.Types.NVARCHAR:
obj.put(column_name, rs.getNString(column_name)); break;
case java.sql.Types.VARCHAR:
obj.put(column_name, rs.getString(column_name)); break;
case java.sql.Types.TINYINT:
obj.put(column_name, rs.getInt(column_name)); break;
case java.sql.Types.SMALLINT:
obj.put(column_name, rs.getInt(column_name)); break;
case java.sql.Types.DATE:
obj.put(column_name, rs.getDate(column_name)); break;
case java.sql.Types.TIMESTAMP:
obj.put(column_name, rs.getTimestamp(column_name)); break;
default:
obj.put(column_name, rs.getObject(column_name)); break;
}
}
json.put(obj);
}
Faster results can be achieved using numpy.where.
For example, with unubtu's setup -
In [76]: df.iloc[np.where(df.A.values=='foo')]
Out[76]:
A B C D
0 foo one 0 0
2 foo two 2 4
4 foo two 4 8
6 foo one 6 12
7 foo three 7 14
Timing comparisons:
In [68]: %timeit df.iloc[np.where(df.A.values=='foo')] # fastest
1000 loops, best of 3: 380 µs per loop
In [69]: %timeit df.loc[df['A'] == 'foo']
1000 loops, best of 3: 745 µs per loop
In [71]: %timeit df.loc[df['A'].isin(['foo'])]
1000 loops, best of 3: 562 µs per loop
In [72]: %timeit df[df.A=='foo']
1000 loops, best of 3: 796 µs per loop
In [74]: %timeit df.query('(A=="foo")') # slowest
1000 loops, best of 3: 1.71 ms per loop
This worked for me:
On terminal type the following
$ sudo mysql -u root -p

If you're trying to do this from the command line, you may be encountering an issue where a machine-wide environment variable 'Platform' is being set for you and working against you. I can reproduce this if I use the VS2012 Command window instead of a regular windows Command window.
At the command prompt type:
set platform
In a VS2012 Command window, I have a value of 'X64' preset. That seems to interfere with whatever is in my solution file.
In a regular Command window, the 'set' command results in a "variable not defined" message...which is good.
If the result of your 'set' command above returns no environment variable value, you should be good to go.
You can also use sqlcmd
mode for this (enable this on the "Query" menu in Management Studio).
:setvar dbname "TEST"
CREATE DATABASE $(dbname)
GO
ALTER DATABASE $(dbname) SET COMPATIBILITY_LEVEL = 90
GO
ALTER DATABASE $(dbname) SET RECOVERY SIMPLE
GO
EDIT:
Check this MSDN article to set parameters via the SQLCMD tool.
Here's what worked well for me:
find . -path '*/.svn' -prune -o -type f -exec gawk '/Dansk/{a=1}/Norsk/{b=1}/Svenska/{c=1}END{ if (a && b && c) print FILENAME }' {} \;
./path/to/file1.sh
./another/path/to/file2.txt
./blah/foo.php
If I just wanted to find .sh files with these three, then I could have used:
find . -path '*/.svn' -prune -o -type f -name "*.sh" -exec gawk '/Dansk/{a=1}/Norsk/{b=1}/Svenska/{c=1}END{ if (a && b && c) print FILENAME }' {} \;
./path/to/file1.sh
Note: This code is untested
Define a record for your refCursor return type, call it rec. For example:
TYPE MyRec IS RECORD (col1 VARCHAR2(10), col2 VARCHAR2(20), ...); --define the record
rec MyRec; -- instantiate the record
Once you have the refcursor returned from your procedure, you can add the following code where your comments are now:
LOOP
FETCH refCursor INTO rec;
EXIT WHEN refCursor%NOTFOUND;
dbms_output.put_line(rec.col1||','||rec.col2||','||...);
END LOOP;
Datatables have a .Select method, which returns a rows array according to the criteria you specify. Something like this:
Dim oRows() As DataRow
oRows = dtCountries.Select("CountryName = '" & userinput & "'")
If oRows.Count = 0 Then
' No rows found
Else
' At least one row found. Could be more than one
End If
Of course, if userinput contains ' character, it would raise an exception (like if you query the database). You should escape the ' characters (I use a function to do that).
Use
npm uninstall <package_name>
Example to uninstall express
npm uninstall express
Try something like this to convert JToken to JArray:
static public JArray convertToJArray(JToken obj)
{
// if ((obj).Type == JTokenType.Null) --> You can check if it's null here
if ((obj).Type == JTokenType.Array)
return (JArray)(obj);
else
return new JArray(); // this will return an empty JArray
}
I really like the clean approach from this gist using Promise.race
fetchWithTimeout.js
export default function (url, options, timeout = 7000) {
return Promise.race([
fetch(url, options),
new Promise((_, reject) =>

Prefer initialization:
class C : public A
{
public:
C(const string &val) : A(anInt) {}
};
In C++11, you can use inheriting constructors (which has the syntax seen in your example D
).
Update: Inheriting Constructors have been available in GCC since version 4.8.
If you don't find initialization appealing (e.g. due to the number of possibilities in your actual case), then you might favor this approach for some TMP constructs:
class A
{
public:
A() {}
virtual ~A() {}
void init(int) { std::cout << "A\n"; }
};
class B : public A
{
public:
B() : A() {}
void init(int) { std::cout << "B\n"; }
};
class C : public A
{
public:
C() : A() {}
void init(int) { std::cout << "C\n"; }
};
class D : public A
{
public:
D() : A() {}
using A::init;
void init(const std::string& s) { std::cout << "D -> " << s << "\n"; }
};
int main()
{
B b; b.init(10);
C c; c.init(10);
D d; d.init(10); d.init("a");
return 0;
}
AS from the above discussion
[ng-cloak] {
display: none;
}
is the perfect way to solve the Problem.
Your HttpServletRequest
object has a getParameter(String paramName)
method that can be used to get parameter values. http://java.sun.com/javaee/5/docs/api/javax/servlet/ServletRequest.html#getParameter(java.lang.String)
and
tests whether both expressions are logically True
while &
(when used with True
/False
values) tests if both are True
.
In Python, empty built-in objects are typically treated as logically False
while non-empty built-ins are logically True
. This facilitates the common use case where you want to do something if a list is empty and something else if the list is not. Note that this means that the list [False] is logically True
:
>>> if [False]:
... print 'True'
...
True
So in Example 1, the first list is non-empty and therefore logically True
, so the truth value of the and
is the same as that of the second list. (In our case, the second list is non-empty and therefore logically True
, but identifying that would require an unnecessary step of calculation.)
For example 2, lists cannot meaningfully be combined in a bitwise fashion because they can contain arbitrary unlike elements. Things that can be combined bitwise include: Trues and Falses, integers.
NumPy objects, by contrast, support vectorized calculations. That is, they let you perform the same operations on multiple pieces of data.
Example 3 fails because NumPy arrays (of length > 1) have no truth value as this prevents vector-based logic confusion.
Example 4 is simply a vectorized bit and
operation.
Bottom Line
If you are not dealing with arrays and are not performing math manipulations of integers, you probably want and
.
If you have vectors of truth values that you wish to combine, use numpy
with &
.
I tried Update-Package -reinstall
but it fails on a package and stopped processing all remaining packages of projects in my solution.
I ended up with my script that enumerates all package.config files and run Update-Package -Reinstall -ProjectName prj -Id pkg
for each project/package.
Hope it can be useful for someone:
$files = Get-ChildItem -Recurse -Include packages.config;
[array]$projectPackages = @();
$files | foreach { [xml]$packageFile = gc $_; $projectName = $_.Directory.Name; $packageFile.packages.package.id | foreach { $projectPackages += @( ,@( $projectName, $_ ) ) } }
$projectPackages | foreach { Update-Package -Reinstall -ProjectName $_[0] -Id $_[1] }
Edit:
This is an error that I had:
Update-Package : Unable to find package 'EntityFramework.BulkInsert-ef6'. Existing packages must be restored before performing an install or update.
Manual run of
Update-Package -Reinstall -ProjectName my_prj -Id EntityFramework.BulkInsert-ef6
worked very well.
In your component i.e angular JS code:
function getData(){
window.location.href = 'http://localhost:1036/api/Employee/GetExcelData';
}
You don't actually declare things, but this is how you create an array in Python:
from array import array
intarray = array('i')
For more info see the array module: http://docs.python.org/library/array.html
Now possible you don't want an array, but a list, but others have answered that already. :)
As simple String extension should suffice:
extension String {
var parseJSONString: AnyObject? {
let data = self.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
if let jsonData = data {
// Will return an object or nil if JSON decoding fails
return NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers, error: nil)
} else {
// Lossless conversion of the string was not possible
return nil
}
}
}
Then:
var jsonString = "[\n" +
"{\n" +
"\"id\":72,\n" +
"\"name\":\"Batata Cremosa\",\n" +
"},\n" +
"{\n" +
"\"id\":183,\n" +
"\"name\":\"Caldeirada de Peixes\",\n" +
"},\n" +
"{\n" +
"\"id\":76,\n" +
"\"name\":\"Batata com Cebola e Ervas\",\n" +
"},\n" +
"{\n" +
"\"id\":56,\n" +
"\"name\":\"Arroz de forma\",\n" +
"}]"
let json: AnyObject? = jsonString.parseJSONString
println("Parsed JSON: \(json!)")
println("json[3]: \(json![3])")
/* Output:
Parsed JSON: (
{
id = 72;
name = "Batata Cremosa";
},
{
id = 183;
name = "Caldeirada de Peixes";
},
{
id = 76;
name = "Batata com Cebola e Ervas";
},
{
id = 56;
name = "Arroz de forma";
}
)
json[3]: {

name = "Arroz de forma";
}
*/
It depends a bit on your needs. Some toolkits are better at drawing, others are better for writing text. Cairo has a pretty good for drawing (it support a wide range of screen and file types, including pdf), but it may not be ideal for good typography.

If you want to remove everything after the last occurrence of separator in a string I find this works well:
<separator>.join(string_to_split.split(<separator>)[:-1])
For example, if string_to_split
is a path like root/location/child/too_far.exe
and you only want the folder path, you can split by "/".join(string_to_split.split("/")[:-1])
and you'll get
root/location/child
What I did is first check what are the running processes by
SELECT * FROM pg_stat_activity WHERE state = 'active';
Find the process you want to kill, then type:
SELECT pg_cancel_backend(<pid of the process>)
This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.
If the process cannot be killed, try:
SELECT pg_terminate_backend(<pid of the process>)
@Cabbi raised the issue that on some systems, the microseconds format %f
may give "0"
, so it's not portable to simply chop off the last three characters.
The following code carefully formats a timestamp with milliseconds:
from datetime import datetime
(dt, micro) = datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f').split('.')
dt = "%s.%03d" % (dt, int(micro) / 1000)
print dt
Example Output:
2016-02-26 04:37:53.133
To get the exact output that the OP wanted, we have to strip punctuation characters:
from datetime import datetime
(dt, micro) = datetime.utcnow().strftime('%Y%m%d%H%M%S.%f').split('.')
dt = "%s%03d" % (dt, int(micro) / 1000)
print dt
Example Output:
20160226043839901
The case class construct in Scala can also be seen as a convenience to remove some boilerplate.
When constructing a case class Scala gives you the following.
apply
method that you are able to use as a factory method. You get the syntactic sugar advantage of not having to use the new keyword.
Because the class is immutable you get accessors, which are just the variables (or properties) of the class but no mutators (so no ability to change the variables). The constructor parameters are automatically available to you as public read only fields. Much nicer to use than Java bean construct.
hashCode
, equals
, and toString
methods by default and the equals
method compares an object structurally. A copy
method is generated to be able to clone an object (with some fields having new values provided to the method). The biggest advantage as has been mentioned previously is the fact that you can pattern match on case classes. The reason for this is because you get the unapply
method which lets you deconstruct a case class to extract its fields.
In essence what you are getting from Scala when creating a case class (or a case object if your class takes no arguments) is a singleton object which serves the purpose as a factory and as an extractor .
My understanding is that HEAD points the current branch, while ORIG_HEAD is used to store the previous HEAD before doing "dangerous" operations.
For example git-rebase and git-am record the original tip of branch before they apply any changes.
p {
float: left;
margin: 0;
}
No spacing will be around, it looks similar to span.
VanillaJS === JavaScript i.e.VanillaJS is native JavaScript
Why, Vanilla says it all!!!
Computer software, and sometimes also other computing-related systems like computer hardware or algorithms, are called vanilla when not customized from their original form, meaning that they are used without any customization or updates applied to them (Refer this article). So Vanilla often refers to pure or plain.
In the English language Vanilla has a similar meaning, In information technology, vanilla (pronounced vah-NIHL-uh ) is an adjective meaning plain or basic. Or having no special or extra features, ordinary or standard.
So why name it VanillaJS? As the accepted answer says some bosses want to work with a framework (because it's more organized and flexible and do all the things we want??) but simply JavaScript will do the job. Yet you need to add a framework somewhere. Use VanillaJS...
Is it a Joke? YES

The attribute selectors are often used for inputs. This is the list of attribute selectors:
[title] All elements with the title attribute are selected.
[title=banana] All elements which have the 'banana' value of the title attribute.
[title~=banana] All elements which contain 'banana' in the value of the title attribute.
[title|=banana] All elements which value of the title attribute starts with 'banana'.
[title^=banana] All elements which value of the title attribute begins with 'banana'.
[title$=banana] All elements which value of the title attribute ends with 'banana'.
[title*=banana] All elements which value of the title attribute contains the substring 'banana'.

if you want to log the error etc you should use try/catch, if you dont; just put @ before mysql_query
edit : you can use try catch like this; so you can log the error and let the page continue to load
function throw_ex($er){
throw new Exception($er);
}
try {
mysql_connect(localhost,'user','pass');
mysql_select_db('test');
$q = mysql_query('select * from asdasda') or throw_ex(mysql_error());
}
catch(exception $e) {
echo "ex: ".$e;

// Promise 3 runs last, but completes first (with a rejection)
// Note the catch to trap the error immediately
const p3 = test(1000, false).catch(e => console.log(e));
// Await all in parallel
const r = await Promise.all([p1, p2, p3]);
// Display the results
console.log(r);
};
// Run the handler
handler();
/*

Whilst setting p1, p2 and p3 is not strictly running them in parallel, they do not hold up any execution and you can trap contextual errors with a catch.

--first-only
convert only leading sequences of blanks (overrides -a)
-t, --tabs=N
have tabs N characters apart instead of 8 (enables -a)
-t, --tabs=LIST
use comma separated LIST of tab positions (enables -a)
--help display this help and exit
--version
output version information and exit
. . .
STANDARDS
The expand and unexpand utilities conform to IEEE Std 1003.1-2001
(``POSIX.1'').
Window -> Show View -> Other -> Studio/Remote

The explicit way of saying "search until X
but not including X
" is:
(?:(?!X).)*
where X
can be any regular expression.
In your case, though, this might be overkill - here the easiest way would be
[^z]*
This will match anything except z
and therefore stop right before the next z
.
So .*?quick[^z]*
will match The quick fox jumps over the la
.
However, as soon as you have more than one simple letter to look out for, (?:(?!X).)*
comes into play, for example
(?:(?!lazy).)*
- match anything until the start of the word lazy
.
This is using a lookahead assertion, more specifically a negative lookahead.
.*?quick(?:(?!lazy).)*
will match The quick fox jumps over the
.
Explanation:
(?: # Match the following but do not capture it:
(?!lazy) # (first assert that it's not possible to match "lazy" here
. # then match any character
)* # end of group, zero or more repetitions.
Furthermore, when searching for keywords, you might want to surround them with word boundary anchors: \bfox\b
will only match the complete word fox
but not the fox in foxy
.
Note
If the text to be matched can also include linebreaks, you will need to set the "dot matches all" option of your regex engine. Usually, you can achieve that by prepending (?s)
to the regex, but that doesn't work in all regex engines (notably JavaScript).
Alternative solution:
In many cases, you can also use a simpler, more readable solution that uses a lazy quantifier. By adding a ?
to the *
quantifier, it will try to match as few characters as possible from the current position:
.*?(?=(?:X)|$)
will match any number of characters, stopping right before X
(which can be any regex) or the end of the string (if X
doesn't match). You may also need to set the "dot matches all" option for this to work. (Note: I added a non-capturing group around X
in order to reliably isolate it from the alternation)
Since mobile doesn't give hover feedback, I want, as a user, to see instant feedback when a link is tapped. I noticed that -webkit-tap-highlight-color
is the fastest to respond (subjective).
Add the following to your body and your links will have a tap effect.
body {
-webkit-tap-highlight-color: #ccc;
}
Can't think of a only css solution, but couldn't you just had a div between those 2 and set in the css the properties to look like a line like shown in the image? If you are using divs as they were table cells this is a pretty simple solution to the problem
// image from res/drawable
int resID = getResources().getIdentifier("my_image",
"drawable", getPackageName());
// view
int resID = getResources().getIdentifier("my_resource",
"id", getPackageName());
// string
int resID = getResources().getIdentifier("my_string",
"string", getPackageName());
It gives you the remainder of a division.
int c=11, d=5;
cout << (c/d) * d + c % d; // gives you the value of c
The easiest solution is going to the config.js and setting:
config.allowedContent = true;
(Remember to clear browser's cache). Then CKEditor stops filtering the inputted content at all. However, this will totally disable content filtering which is one of the most important CKEditor features.
You can also configure CKEditor's content filter more precisely to allow only these element, classes, styles and attributes which you need. This solution is much better, because CKEditor will still remove a lot of crappy HTML which browsers produce when copying and pasting content, but it will not strip the content you want.
For example, you can extend the default CKEditor's configuration to accept all div classes:
config.extraAllowedContent = 'div(*)';
Or some Bootstrap stuff:
config.extraAllowedContent = 'div(col-md-*,container-fluid,row)';
Or you can allow description lists with optional dir
attributes for dt
and dd
elements:
config.extraAllowedContent = 'dl; dt dd[dir]';
These were just very basic examples. You can write all kind of rules - requiring attributes, classes or styles, matching only special elements, matching all elements. You can also disallow stuff and totally redefine CKEditor's rules. Read more about:
Just an other java example:
long dayLength = 1000 * 60 * 60 * 24;
long dayMs = System.currentTimeMillis() % dayLength;
double percentOfDay = (double) dayMs / dayLength;
int hour = (int) (percentOfDay * 24);
int minute = (int) (percentOfDay * 24 * 60) % 60;
int second = (int) (percentOfDay * 24 * 60 * 60) % 60;
an advantage is that you can simulate shorter days, if you adjust dayLength
Alternatively,
<style type="text/css">
#example {
display: block;
width: 30px;
height: 10px;
background: url(../images/example.png) no-repeat;
text-indent: -9999px;
}
</style>
<a href="http://www.example.com" id="example">See an example!</a>
More wordy, but it may benefit SEO, and it will look like nice simple text with CSS disabled.
$("#myTextBox").on("change paste keyup select", function() {
alert($(this).val());
});

To get all objects in a dictionary, you can also use enumerateKeysAndObjectsUsingBlock:
like so:
NSMutableArray *yourArray = [NSMutableArray arrayWithCapacity:6];
[yourDict enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
[yourArray addObject:obj];
}];
Just paste this into your line of codes:

There is not technically a way to draw a circle with HTML (there isn’t a <circle>
HTML tag), but a circle can be drawn.
The best way to draw one is to add border-radius: 50%
to a tag such as div
. Here’s an example:
<div style="width: 50px; height: 50px; border-radius: 50%;">You can put text in here.....</div>
However I get an error which doesn't make sense seeing as the column's data type was properly modified?
| Level | Code | Msg | Warn | 12 | Data truncated for column 'incoming_Cid' at row 1
You can often get this message when you are doing something like the following:
REPLACE INTO table2 (SELECT * FROM table1);
Resulted in our case in the following error:
SQL Exception: Data truncated for column 'level' at row 1
The problem turned out to be column misalignment that resulted in a tinyint
trying to be stored in a datetime
field or vice versa.
Like this:
import operator
l = [...]
sorted_list = sorted(l, key=operator.itemgetter(desired_item_index))
You can do this dynamically - in case you encounter not only: HH:mm:ss, but also, mm:ss, or even ss alone.
var str = '12:99:07';
var times = str.split(":");
times.reverse();
var x = times.length, y = 0, z;
for (var i = 0; i < x; i++) {
z = times[i] * Math.pow(60, i);
y += z;
}
console.log(y);
For your code
var mytextvalue = document.getElementById("mytext");
mytextvalue
will contain null
if you have a document.write()
statement before this code. So remove the document.write
statement and you should get a proper text object in the variable mytextvalue
.
This is caused by document.write
changing the document.
Check out yowsup
https://github.com/tgalal/yowsup
Yowsup is a python library that allows you to do all the previous in your own app. Yowsup allows you to login and use the Whatsapp service and provides you with all capabilities of an official Whatsapp client, allowing you to create a full-fledged custom Whatsapp client.
A solid example of Yowsup's usage is Wazapp. Wazapp is full featured Whatsapp client that is being used by hundreds of thousands of people around the world. Yowsup is born out of the Wazapp project. Before becoming a separate project, it was only the engine powering Wazapp. Now that it matured enough, it was separated into a separate project, allowing anyone to build their own Whatsapp client on top of it. Having such a popular client as Wazapp, built on Yowsup, helped bring the project into a much advanced, stable and mature level, and ensures its continuous development and maintaince.
Yowsup also comes with a cross platform command-line frontend called yowsup-cli. yowsup-cli allows you to jump into connecting and using Whatsapp service directly from command line.
While I haven't found a good way to specify proxy network credentials in the web.config, you might find that you can still use a non-coding solution, by including this in your web.config:
<system.net>
<defaultProxy useDefaultCredentials="true">
<proxy proxyaddress="proxyAddress" usesystemdefault="True"/>
</defaultProxy>
</system.net>
The key ingredient in getting this going, is to change the IIS settings, ensuring the account that runs the process has access to the proxy server. If your process is running under LocalService, or NetworkService, then this probably won't work. Chances are, you'll want a domain account.
The clean way to use mbstowcs
is to call it twice to find the length of the result:
const char * cs = <your input char*>
size_t wn = mbsrtowcs(NULL, &cs, 0, NULL);
// error if wn == size_t(-1)
wchar_t * buf = new wchar_t[wn + 1](); // value-initialize to 0 (see below)
wn = mbsrtowcs(buf, &cs, wn + 1, NULL);
// error if wn == size_t(-1)
assert(cs == NULL); // successful conversion
// result now in buf, return e.g. as std::wstring
delete[] buf;
Don't forget to call setlocale(LC_CTYPE, "");
at the beginning of your program!
The advantage over the Windows MultiByteToWideChar
is that this is entirely standard C, although on Windows you might prefer the Windows API function anyway.
I usually wrap this method, along with the opposite one, in two conversion functions string
->wstring
and wstring
->string
. If you also add trivial overloads string
->string
and wstring
->wstring
, you can easily write code that compiles with the Winapi TCHAR
typedef in any setting.
[Edit:] I added zero-initialization to buf
, in case you plan to use the C array directly. I would usually return the result as std::wstring(buf, wn)
, though, but do beware if you plan on using C-style null-terminated arrays.[/]
In a multithreaded environment you should pass a thread-local conversion state to the function as its final (currently invisible) parameter.
Here is a small rant of mine on this topic.
Just add
position: relative;
top: 50%;
transform: translateY(-50%);
to the inner div.
What it does is moving the inner div's top border to the half height of the outer div (top: 50%;
) and then the inner div up by half its height (transform: translateY(-50%)
). This will work with position: absolute
or relative
.
Keep in mind that transform
and translate
have vendor prefixes which are not included for simplicity.

The Watcher method fires on every character input. So, I built this code based on onFocusChange method:
public static boolean comS(String s1,String s2){
if (s1.length()==s2.length()){
int l=s1.length();
for (int i=0;i<l;i++){
if (s1.charAt(i)!=s2.charAt(i))return false;
}
return true;
}
return false;
}
public void onChange(final EditText EdTe, final Runnable FRun){
class finalS{String s="";}
final finalS dat=new finalS();
EdTe.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {dat.s=""+EdTe.getText();}
else if (!comS(dat.s,""+EdTe.getText())){(new Handler()).post(FRun);}
}
});
}
To using it, just call like this:
onChange(YourEditText, new Runnable(){public void run(){
// V V YOUR WORK HERE
}}
);
You can ignore the comS function by replace the !comS(dat.s,""+EdTe.getText()) with !equal function. However the equal function itself some time work not correctly in run time.
The onChange listener will remember old data of EditText when user focus typing, and then compare the new data when user lose focus or jump to other input. If comparing old String not same new String, it fires the work.
If you only have 1 EditText, then u will need to make a ClearFocus function by making an Ultimate Secret Transparent Micro EditText outside the windows and request focus to it, then hide the keyboard via Import Method Manager.
I took Sebastian's answer and added a keyExtractor to it -
private <U, T> Set<T> findDuplicates(Collection<T> collection, Function<? super T,? extends U> keyExtractor) {
Map<U, T> uniques = new HashMap<>(); // maps unique keys to corresponding values
return collection.stream()
.filter(e -> uniques.put(keyExtractor.apply(e), e) != null)
.collect(Collectors.toSet());
}
Or if you want a ripple pulse effect, you could use this:
http://jsfiddle.net/Fy8vD/3041/
.gps_ring {
border: 2px solid #fff;
-webkit-border-radius: 50%;
height: 18px;
width: 18px;
position: absolute;
left:20px;
top:214px;
-webkit-animation: pulsate 1s ease-out;
-webkit-animation-iteration-count: infinite;
opacity: 0.0;
}
.gps_ring:before {
content:"";
display:block;
border: 2px solid #fff;
-webkit-border-radius: 50%;
height: 30px;
width: 30px;
position: absolute;
left:-8px;
top:-8px;
-webkit-animation: pulsate 1s ease-out;
-webkit-animation-iteration-count: infinite;
-webkit-animation-delay: 0.1s;
opacity: 0.0;
}
.gps_ring:after {
content:"";
display:block;
border:2px solid #fff;
-webkit-border-radius: 50%;
height: 50px;
width: 50px;
position: absolute;
left:-18px;
top:-18px;
-webkit-animation: pulsate 1s ease-out;
-webkit-animation-iteration-count: infinite;
-webkit-animation-delay: 0.2s;
opacity: 0.0;
}
@-webkit-keyframes pulsate {
0% {-webkit-transform: scale(0.1, 0.1); opacity: 0.0;}
50% {opacity: 1.0;}
100% {-webkit-transform: scale(1.2, 1.2); opacity: 0.0;}
}
If you want to first take mean on the combination of ['cluster', 'org']
and then take mean on cluster
groups, you can use:
In [59]: (df.groupby(['cluster', 'org'], as_index=False).mean()
.groupby('cluster')['time'].mean())
Out[59]:
cluster
1 15
2 54
3 6
Name: time, dtype: int64
If you want the mean of cluster
groups only, then you can use:
In [58]: df.groupby(['cluster']).mean()
Out[58]:
time
cluster
1 12.333333
2 54.000000
3 6.000000
You can also use groupby
on ['cluster', 'org']
and then use mean()
:
In [57]: df.groupby(['cluster', 'org']).mean()
Out[57]:
time
cluster org
1 a 438886
c 23
2 d 9874
h 34
3 w 6
It will be found in /usr/local/mysql
if you use the mysql binaries or dmg to install it on your system instead of using MAMP
