Here is what worked for me:
protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
HttpWebRequest request;
request = (HttpWebRequest)base.GetWebRequest(uri);
NetworkCredential networkCredentials =
Credentials.GetCredential(uri, "Basic");
if (networkCredentials != null)
{
byte[] credentialBuffer = new UTF8Encoding().GetBytes(
networkCredentials.UserName + ":" +
networkCredentials.Password);
request.Headers["Authorization"] =
"Basic " + Convert.ToBase64String(credentialBuffer);
request.Headers["Cookie"] = "BCSI-CS-2rtyueru7546356=1";
request.Headers["Cookie2"] = "$Version=1";
}
else
{
throw new ApplicationException("No network credentials");
}
return request;
}
Don't forget to set this property:
service.Credentials = new NetworkCredential("username", "password");
Cookie and Cookie2 are set in header because java service was not accepting the request and I was getting Unauthorized error.
You can use pop()
:
x=[2,3,4,5,6,7]
print(x.pop(2))
The following code should be considered bad form, regardless of language or desired functionality:
while( true ) {
}
The while( true )
loop is poor form because it:
while(true)
for loops that are not infinite, we lose the ability to concisely communicate when loops actually have no terminating condition. (Arguably, this has already happened, so the point is moot.)The following code is better form:
while( isValidState() ) {
execute();
}
bool isValidState() {
return msg->state != DONE;
}
No flag. No goto
. No exception. Easy to change. Easy to read. Easy to fix. Additionally the code:
The second point is important. Without knowing how the code works, if someone asked me to make the main loop let other threads (or processes) have some CPU time, two solutions come to mind:
Readily insert the pause:
while( isValidState() ) {
execute();
sleep();
}
Override execute:
void execute() {
super->execute();
sleep();
}
This code is simpler (thus easier to read) than a loop with an embedded switch
. The isValidState
method should only determine if the loop should continue. The workhorse of the method should be abstracted into the execute
method, which allows subclasses to override the default behaviour (a difficult task using an embedded switch
and goto
).
Contrast the following answer (to a Python question) that was posted on StackOverflow:
while True:
choice = raw_input('What do you want? ')
if choice == 'restart':
continue
else:
break
print 'Break!'
Versus:
choice = 'restart';
while choice == 'restart':
choice = raw_input('What do you want? ')
print 'Break!'
Here, while True
results in misleading and overly complex code.
Use discard
from purrr (works with lists and vectors).
discard(v, is.na)
The benefit is that it is easy to use pipes; alternatively use the built-in subsetting function [
:
v %>% discard(is.na)
v %>% `[`(!is.na(.))
Note that na.omit
does not work on lists:
> x <- list(a=1, b=2, c=NA)
> na.omit(x)
$a
[1] 1
$b
[1] 2
$c
[1] NA

I hope that helps.
Imagine incrementing a counter in some component:
class SomeComponent extends Component{
state = {
updatedByDiv: '',
updatedByBtn: '',
counter: 0
}
divCountHandler = () => {
this.setState({
updatedByDiv: 'Div',
counter: this.state.counter + 1
});
console.log('divCountHandler executed');
}
btnCountHandler = () => {
this.setState({
updatedByBtn: 'Button',
counter: this.state.counter + 1
});
console.log('btnCountHandler executed');
}
...
...
render(){
return (
...
// a parent div
<div onClick={this.divCountHandler}>
// a child button
<button onClick={this.btnCountHandler}>Increment Count</button>
</div>
...
)
}
}
There is a count handler attached to both the parent and the child components. This is done purposely so we can execute the setState() twice within the same click event bubbling context, but from within 2 different handlers.
As we would imagine, a single click event on the button would now trigger both these handlers since the event bubbles from target to the outermost container during the bubbling phase.
Therefore the btnCountHandler() executes first, expected to increment the count to 1 and then the divCountHandler() executes, expected to increment the count to 2.
However the count only increments to 1 as you can inspect in React Developer tools.
This proves that react
queues all the setState calls
comes back to this queue after executing the last method in the context(the divCountHandler in this case)
merges all the object mutations happening within multiple setState calls in the same context(all method calls within a single event phase is same context for e.g.) into one single object mutation syntax (merging makes sense because this is why we can update the state properties independently in setState() in the first place)
and passes it into one single setState() to prevent re-rendering due to multiple setState() calls (this is a very primitive description of batching).
Resultant code run by react:
this.setState({
updatedByDiv: 'Div',
updatedByBtn: 'Button',
counter: this.state.counter + 1
})
To stop this behaviour, instead of passing objects as arguments to the setState method, callbacks are passed.
divCountHandler = () => {
this.setState((prevState, props) => {
return {
updatedByDiv: 'Div',
counter: prevState.counter + 1
};
});
console.log('divCountHandler executed');
}
btnCountHandler = () => {
this.setState((prevState, props) => {
return {
updatedByBtn: 'Button',
counter: prevState.counter + 1
};
});
console.log('btnCountHandler executed');
}
After the last method finishes execution and when react returns to process the setState queue, it simply calls the callback for each setState queued, passing in the previous component state.
This way react ensures that the last callback in the queue gets to update the state that all of its previous counterparts have laid hands on.

<label for="radio3">Archived</label>_x000D_
</div>

First of all, you probably want to add the name
attribute on the radio buttons. Otherwise, they are not part of the same group, and multiple radio buttons can be checked.
Also, since I placed the labels as siblings (of the radio buttons), I had to use the id
and for
attributes to associate them together.

Two issues:
You're passing the jQuery wrapper of the element into parseInt
, which isn't what you want, as parseInt
will call toString
on it and get back "[object Object]"
. You need to use val
or text
or something (depending on what the element is) to get the string you want.
You're not telling parseInt
what radix (number base) it should use, which puts you at risk of odd input giving you odd results when parseInt
guesses which radix to use.
Fix if the element is a form field:
// vvvvv-- use val to get the value
var test = parseInt($("#testid").val(), 10);
// ^^^^-- tell parseInt to use decimal (base 10)
Fix if the element is something else and you want to use the text within it:
// vvvvvv-- use text to get the text
var test = parseInt($("#testid").text(), 10);
// ^^^^-- tell parseInt to use decimal (base 10)
I know is quite old, but I'll say just for the sake of it - I was looking for the same problem and got here, but I needed the difference in days.
I used SELECT (UNIX_TIMESTAMP(DATE1) - UNIX_TIMESTAMP(DATE2))/60/60/24
Unix_timestamp returns the difference in seconds, and then I just divide into minutes(seconds/60), hours(minutes/60), days(hours/24).

To answer the title of the question (but not the question about the output you're getting):
Copying the following folder from your dev machine to your build server fixes this if it's just web applications
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications
Remove x86 according to how your build breaks. If you have other project types you will probably need to copy the entire msbuild folder.

Note that since git1.7.11 ([ANNOUNCE] Git 1.7.11.rc1 and release note, June 2012) mentions:
"
git push --recurse-submodules
" learned to optionally look into the histories of submodules bound to the superproject and push them out.
Probably done after this patch and the --on-demand
option:
recurse-submodules=<check|on-demand>::
Make sure all submodule commits used by the revisions to be pushed are available on a remote tracking branch.
- If
check
is used, it will be checked that all submodule commits that changed in the revisions to be pushed are available on a remote.
Otherwise the push will be aborted and exit with non-zero status.- If
on-demand
is used, all submodules that changed in the revisions to be pushed will be pushed.
If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status.
So you could push everything in one go with (from the parent repo) a:
git push --recurse-submodules=on-demand
This option only works for one level of nesting. Changes to the submodule inside of another submodule will not be pushed.
With git 2.7 (January 2016), a simple git push will be enough to push the parent repo... and all its submodules.
See commit d34141c, commit f5c7cd9 (03 Dec 2015), commit f5c7cd9 (03 Dec 2015), and commit b33a15b (17 Nov 2015) by Mike Crowe (mikecrowe

push
: addrecurseSubmodules
config optionThe
--recurse-submodules
command line parameter has existed for some time but it has no config file equivalent.Following the style of the corresponding parameter for
git fetch
, let's inventpush.recurseSubmodules
to provide a default for this parameter.
This also requires the addition of--recurse-submodules=no
to allow the configuration to be overridden on the command line when required.The most straightforward way to implement this appears to be to make
push
use code insubmodule-config
in a similar way tofetch
.
The git config
doc now include:
push.recurseSubmodules
:Make sure all submodule commits used by the revisions to be pushed are available on a remote-tracking branch.
- If the value is '
check
', then Git will verify that all submodule commits that changed in the revisions to be pushed are available on at least one remote of the submodule. If any commits are missing, the push will be aborted and exit with non-zero status.- If the value is '
on-demand
' then all submodules that changed in the revisions to be pushed will be pushed. If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status. -- If the value is '
no
' then default behavior of ignoring submodules when pushing is retained.You may override this configuration at time of push by specifying '
--recurse-submodules=check|on-demand|no
'.
So:
git config push.recurseSubmodules on-demand
git push
Git 2.12 (Q1 2017)
git push --dry-run --recurse-submodules=on-demand
will actually work.
See commit 0301c82, commit 1aa7365 (17 Nov 2016) by Brandon Williams (mbrandonw
).
(Merged by Junio C Hamano -- gitster
-- in commit 12cf113, 16 Dec 2016)
push run with --dry-run
doesn't actually (Git 2.11 Dec. 2016 and lower/before) perform a dry-run when push is configured to push submodules on-demand.
Instead all submodules which need to be pushed are actually pushed to their remotes while any updates for the superproject are performed as a dry-run.
This is a bug and not the intended behaviour of a dry-run.Teach
push
to respect the--dry-run
option when configured to recursively push submodules 'on-demand'.
This is done by passing the--dry-run
flag to the child process which performs a push for a submodules when performing a dry-run.
And still in Git 2.12, you now havea "--recurse-submodules=only
" option to push submodules out without pushing the top-level superproject.

I've created a small plugin (available on NuGet) that allows you to add any (if supported by your terminal) color to your console output, without the limitations of the classic solutions.
It works by extending the String
object and the syntax is very simple:
"colorize me".Pastel("#1E90FF");
Both foreground and background colors are supported.
You can simply write
new ArrayList<MyEnum>(Arrays.asList(MyEnum.values()));

The simplest answer, in my case needing to ensure one onboarding tutorial view was portrait-only:
extension myViewController {
//manage rotation for this viewcontroller
override open var supportedInterfaceOrientations: UIInterfaceOrientationMask {
return .portrait
}
}
Eezy-peezy.
you can also use this code...
datePicker = (DatePicker) findViewById(R.id.schedule_datePicker);
int day = datePicker.getDayOfMonth();
int month = datePicker.getMonth() + 1;
int year = datePicker.getYear();
SimpleDateFormat dateFormatter = new SimpleDateFormat("MM-dd-yyyy");
Date d = new Date(year, month, day);
String strDate = dateFormatter.format(d);
It's very simple try integrate these lines of code first take permission in the Android Manifest file
<uses-permission android:name="android.permission.INTERNET" />
then write some code in you Activity.xml
<?xml version="1.0" encoding="utf-8"?>

Create the classLoader instance of the class you need, then you can access the files or resources easily.
now you access path using getPath()

System.out.println(path);
A way that can be fastest, especially if your list has a lot of records, is to use operator.attrgetter("count")
. However, this might run on an pre-operator version of Python, so it would be nice to have a fallback mechanism. You might want to do the following, then:
try: import operator
except ImportError: keyfun= lambda x: x.count # use a lambda if no operator module
else: keyfun= operator.attrgetter("count") # use operator since it's faster than lambda
ut.sort(key=keyfun, reverse=True) # sort in-place
You can try this it will recursively find all key values in a json object and constructs as a map . You can simply get which key you want from the Map .
public static Map<String,String> parse(JSONObject json , Map<String,String> out) throws JSONException{
Iterator<String> keys = json.keys();
while(keys.hasNext()){
String key = keys.next();
String val = null;
try{
JSONObject value = json.getJSONObject(key);
parse(value,out);
}catch(Exception e){
val = json.getString(key);
}
if(val != null){
out.put(key,val);
}
}
return out;
}
public static void main(String[] args) throws JSONException {
String json = "{'ipinfo': {'ip_address': '131.208.128.15','ip_type': 'Mapped','Location': {'continent': 'north america','latitude': 30.1,'longitude': -81.714,'CountryData': {'country': 'united states','country_code': 'us'},'region': 'southeast','StateData': {'state': 'florida','state_code': 'fl'},'CityData': {'city': 'fleming island','postal_code': '32003','time_zone': -5}}}}";
JSONObject object = new JSONObject(json);
JSONObject info = object.getJSONObject("ipinfo");
Map<String,String> out = new HashMap<String, String>();
parse(info,out);
String latitude = out.get("latitude");
String longitude = out.get("longitude");
String city = out.get("city");
String state = out.get("state");
String country = out.get("country");
String postal = out.get("postal_code");
System.out.println("Latitude : " + latitude + " LongiTude : " + longitude + " City : "+city + " State : "+ state + " Country : "+country+" postal "+postal);
System.out.println("ALL VALUE " + out);
}
Output:

Method Load
of DataTable
executes NextResult
on the DataReader
, so you shouldn't call NextResult
explicitly when using Load
, otherwise odd tables in the sequence would be omitted.
Here is a generic solution to load multiple tables using a DataReader
.
// your command initialization code here
// ...
DataSet ds = new DataSet();
DataTable t;
using (DbDataReader reader = command.ExecuteReader())
{
while (!reader.IsClosed)
{
t = new DataTable();
t.Load(rs);
ds.Tables.Add(t);
}
}
One thing that caught me out and surprised me was, in an inherited project, the files it was referring to were referred to on a relative path outside of the project folder but yet existed in the project folder.
In solution explorer, single click each file with the error, bring up the Properties window (right-click, Properties), and ensure the "Relative Path" is just the file name (e.g. MyMissingFile.cpp
) if it is in the project folder. In my case it was set to: ..\..\Some Other Folder\MyMissingFile.cpp
.
The absolute divs are taken out of the flow of the document so the containing div does not have any content except for the padding. Give #box a height to fill it out.
#box {
background-color: #000;
position: relative;
padding: 10px;
width: 220px;
height:30px;
}
Try this:
if(myString != "-1")
The opperand is !=
and not =!
You can also use Equals
if(!myString.Equals("-1"))
Note the !
before myString
Let's say you have an array of IDs and equivalent array of statuses - here is an example how to do this with a static SQL (a sql query that doesn't change due to different values) of the arrays :
drop table if exists results_dummy;
create table results_dummy (id int, status text, created_at timestamp default now(), updated_at timestamp default now());
-- populate table with dummy rows
insert into results_dummy
(id, status)
select unnest(array[1,2,3,4,5]::int[]) as id, unnest(array['a','b','c','d','e']::text[]) as status;
select * from results_dummy;
-- THE update of multiple rows with/by different values
update results_dummy as rd
set status=new.status, updated_at=now()
from (select unnest(array[1,2,5]::int[]) as id,unnest(array['a`','b`','e`']::text[]) as status) as new
where rd.id=new.id;
select * from results_dummy;
-- in code using **IDs** as first bind variable and **statuses** as the second bind variable:
update results_dummy as rd
set status=new.status, updated_at=now()
from (select unnest(:1::int[]) as id,unnest(:2::text[]) as status) as new
where rd.id=new.id;
You just add the following line to your local ~/.gemrc
file (it is in your home folder):
gem: --no-document
or you can add this line to the global gemrc
config file.
Here is how to find it (in Linux):
strace gem source 2>&1 | grep gemrc
Cleaner and more reusable approach is
define text size in dimens.xml
file inside res/values/
directory:
</resources>
<dimen name="text_medium">14sp</dimen>
</resources>
and then apply it to the TextView
:
textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, context.getResources().getDimension(R.dimen.text_medium));
import pyclbr
print(pyclbr.readmodule(__name__).keys())
Note that the stdlib's Python class browser module uses static source analysis, so it only works for modules that are backed by a real .py
file.
NumPy's arrays are more compact than Python lists -- a list of lists as you describe, in Python, would take at least 20 MB or so, while a NumPy 3D array with single-precision floats in the cells would fit in 4 MB. Access in reading and writing items is also faster with NumPy.
Maybe you don't care that much for just a million cells, but you definitely would for a billion cells -- neither approach would fit in a 32-bit architecture, but with 64-bit builds NumPy would get away with 4 GB or so, Python alone would need at least about 12 GB (lots of pointers which double in size) -- a much costlier piece of hardware!
The difference is mostly due to "indirectness" -- a Python list is an array of pointers to Python objects, at least 4 bytes per pointer plus 16 bytes for even the smallest Python object (4 for type pointer, 4 for reference count, 4 for value -- and the memory allocators rounds up to 16). A NumPy array is an array of uniform values -- single-precision numbers takes 4 bytes each, double-precision ones, 8 bytes. Less flexible, but you pay substantially for the flexibility of standard Python lists!
Ran into another instance of this problem, and in searching for a solution to it came here. My issue was that I was doing the children, and lazy loading of the components as well to optimize things a bit. In short if you are lazy loading the parent module. Main thing was my using '/:id' in the route, and it's complaints about '/' being a part of it. Not the exact problem here, but it applies.
App-routing from parent
...
const routes: Routes = [
{
path: '',
children: [
{
path: 'pathOne',
loadChildren: 'app/views/$MODULE_PATH.module#PathOneModule'
},
{
path: 'pathTwo',
loadChildren: 'app/views/$MODULE_PATH.module#PathTwoModule'
},
...
Child routes lazy loaded
...
const routes: Routes = [
{
path: '',
children: [
{
path: '',
component: OverviewComponent
},
{
path: ':id',
component: DetailedComponent
},
]
}
];
...
You can use the event.persist()
method.
An example follows using underscore's _.debounce()
:
var SearchBox = React.createClass({
componentWillMount: function () {
this.delayedCallback = _.debounce(function (event) {
// `event.target` is accessible now
}, 1000);
},
onChange: function (event) {
event.persist();
this.delayedCallback(event);
},
render: function () {
return (
<input type="search" onChange={this.onChange} />
);
}
});
Edit: See this JSFiddle
Update: the example above shows an uncontrolled component. I use controlled elements all the time so here's another example of the above, but without using the event.persist()
"trickery".
A JSFiddle is available as well. Example without underscore
var SearchBox = React.createClass({
getInitialState: function () {
return {
query: this.props.query
};
},
componentWillMount: function () {
this.handleSearchDebounced = _.debounce(function () {
this.props.handleSearch.apply(this, [this.state.query]);
}, 500);
},
onChange: function (event) {
this.setState({query: event.target.value});
this.handleSearchDebounced();
},
render: function () {
return (
<input type="search"
value={this.state.query}
onChange={this.onChange} />
);
}
});
var Search = React.createClass({
getInitialState: function () {
return {
result: this.props.query
};
},
handleSearch: function (query) {
this.setState({result: query});
},
render: function () {
return (
<div id="search">
<SearchBox query={this.state.result}
handleSearch={this.handleSearch} />
<p>You searched for: <strong>{this.state.result}</strong></p>
</div>
);
}
});
React.render(<Search query="Initial query" />, document.body);
Edit: updated examples and JSFiddles to React 0.12
Edit: updated examples to address the issue raised by Sebastien Lorber
Edit: updated with jsfiddle that does not use underscore and uses plain javascript debounce.
You can calculate screen width. And you can scale bitmap.
public static float getScreenWidth(Activity activity) {
Display display = activity.getWindowManager().getDefaultDisplay();
DisplayMetrics outMetrics = new DisplayMetrics();
display.getMetrics(outMetrics);
float pxWidth = outMetrics.widthPixels;
return pxWidth;
}
calculate screen width and scaled image height by screen width.
float screenWidth=getScreenWidth(act)
float newHeight = screenWidth;
if (bitmap.getWidth() != 0 && bitmap.getHeight() != 0) {
newHeight = (screenWidth * bitmap.getHeight()) / bitmap.getWidth();
}
After you can scale bitmap.
Bitmap scaledBitmap=Bitmap.createScaledBitmap(bitmap, (int) screenWidth, (int) newHeight, true);
Not that anyone would ever have CAPS on when entering a password...but it can give this error.
Most of them already answered to the point. Just as an additional note (based on my understanding and experimenting but not from a documented source), the statement
== if the objects referred to by the variables are equal
from above answers should be read as
== if the objects referred to by the variables are equal and objects belonging to the same type/class
. I arrived at this conclusion based on the below test:
list1 = [1,2,3,4]
tuple1 = (1,2,3,4)
print(list1)
print(tuple1)
print(id(list1))
print(id(tuple1))
print(list1 == tuple1)
print(list1 is tuple1)
Here the contents of the list and tuple are same but the type/class are different.
blog_development doesn't exist
You can see this in sql by the 0 rows affected
message
create it in mysql with
mysql> create database blog_development
However as you are using rails you should get used to using
$ rake db:create
to do the same task. It will use your database.yml file settings, which should include something like:
development:
adapter: mysql2
database: blog_development
pool: 5
Also become familiar with:
$ rake db:migrate # Run the database migration
$ rake db:seed # Run thew seeds file create statements
$ rake db:drop # Drop the database
for anyone reading this because the text inside your label is not vertically centered, keep in mind that some font types are not designed equally. for example, if you create a label with zapfino size 16, you will see the text is not perfectly centered vertically.
however, working with helvetica will vertically center your text.

There is sparrow plugin docker-remove-dangling-images you can use to clean up stopped containers and unused (dangling) images:
$ sparrow plg run docker-remove-dangling-images
It works both for Linux and Windows OS.
Create views on two first "selects" and "union" them.
Mirroring a repository
Create a bare clone of the repository.
git clone --bare https://github.com/exampleuser/old-repository.git
Mirror-push to the new repository.
cd old-repository.git
git push --mirror https://github.com/exampleuser/new-repository.git
Remove the temporary local repository you created in step 1.
cd ..
rm -rf old-repository.git
Mirroring a repository that contains Git Large File Storage objects
Create a bare clone of the repository. Replace the example username with the name of the person or organization who owns the repository, and replace the example repository name with the name of the repository you'd like to duplicate.
git clone --bare https://github.com/exampleuser/old-repository.git
Navigate to the repository you just cloned.
cd old-repository.git
Pull in the repository's Git Large File Storage objects.
git lfs fetch --all
Mirror-push to the new repository.
git push --mirror https://github.com/exampleuser/new-repository.git
Push the repository's Git Large File Storage objects to your mirror.
git lfs push --all https://github.com/exampleuser/new-repository.git
Remove the temporary local repository you created in step 1.
cd ..
rm -rf old-repository.git

I encounter similar situation. I would like to have background of the last .item
to be yellow in the elements that look like...
<div class="container">
<div class="item">item 1</div>
<div class="item">item 2</div>
<div class="item">item 3</div>
...
<div class="item">item x</div>
<div class="other">I'm here for some reasons</div>
</div>
I use nth-last-child(2)
to achieve it.
.item:nth-last-child(2) {
background-color: yellow;
}
It strange to me because nth-last-child of item suppose to be the second of the last item but it works and I got the result as I expect. I found this helpful trick from CSS Trick
This is more of an example where TABLOCK did not work for me and TABLOCKX did.
I have 2 sessions, that both use the default (READ COMMITTED) isolation level:
Session 1 is an explicit transaction that will copy data from a linked server to a set of tables in a database, and takes a few seconds to run. [Example, it deletes Questions] Session 2 is an insert statement, that simply inserts rows into a table that Session 1 doesn't make changes to. [Example, it inserts Answers].
(In practice there are multiple sessions inserting multiple records into the table, simultaneously, while Session 1 is running its transaction).
Session 1 has to query the table Session 2 inserts into because it can't delete records that depend on entries that were added by Session 2. [Example: Delete questions that have not been answered].
So, while Session 1 is executing and Session 2 tries to insert, Session 2 loses in a deadlock every time.
So, a delete statement in Session 1 might look something like this: DELETE tblA FROM tblQ LEFT JOIN tblX on ... LEFT JOIN tblA a ON tblQ.Qid = tblA.Qid WHERE ... a.QId IS NULL and ...
The deadlock seems to be caused from contention between querying tblA while Session 2, [3, 4, 5, ..., n] try to insert into tblA.
In my case I could change the isolation level of Session 1's transaction to be SERIALIZABLE. When I did this: The transaction manager has disabled its support for remote/network transactions.
So, I could follow instructions in the accepted answer here to get around it: The transaction manager has disabled its support for remote/network transactions
But a) I wasn't comfortable with changing the isolation level to SERIALIZABLE in the first place- supposedly it degrades performance and may have other consequences I haven't considered, b) didn't understand why doing this suddenly caused the transaction to have a problem working across linked servers, and c) don't know what possible holes I might be opening up by enabling network access.
There seemed to be just 6 queries within a very large transaction that are causing the trouble.
So, I read about TABLOCK and TabLOCKX.
I wasn't crystal clear on the differences, and didn't know if either would work. But it seemed like it would. First I tried TABLOCK and it didn't seem to make any difference. The competing sessions generated the same deadlocks. Then I tried TABLOCKX, and no more deadlocks.
So, in six places, all I needed to do was add a WITH (TABLOCKX).
So, a delete statement in Session 1 might look something like this: DELETE tblA FROM tblQ q LEFT JOIN tblX x on ... LEFT JOIN tblA a WITH (TABLOCKX) ON tblQ.Qid = tblA.Qid WHERE ... a.QId IS NULL and ...
When testing for directories remember that every directory contains two special files.
One is called '.' and the other '..'
. is the directory's own name while .. is the name of it's parent directory.
To avoid trailing backslash problems just test to see if the directory knows it's own name.
eg:
if not exist %temp%\buffer\. mkdir %temp%\buffer
Isn't it this simple?
var result = _(data)
.groupBy(x => x.color)
.map((value, key) => ({color: key, users: value}))
.value();
if you want to choose dynamically the path to the log file use the method written in this link: method to dynamic choose the log file path.
if you want you can set the path to where your app EXE file exists like this -
var logFileLocation = System.IO.Path.GetDirectoryName
(System.Reflection.Assembly.GetEntryAssembly().Location);
and then send this 'logFileLocation' to the method written in the link above like this:
Initialize(logFileLocation);
and you are ready to go! :)
I recommend initializing variables in constructors. That's why they exist: to ensure your objects are constructed (initialized) properly.
Either way will work, and it's a matter of style, but I prefer constructors for member initialization.
Prior to HTML5, input type="text" simply means a field to insert free text, regardless of what you want it be. that is the job of validations you would have to do in order to guarantee the user enters a valid number
If you're using HTML5, you can use the new input types, one of which is number that automatically validates the text input, and forces it to be a number
keep in mind though, that if you're building a server side app (php for example) you will still have to validate the input on that side (make sure it is really a number) since it's pretty easy to hack the html and change the input type, removing the browser validation
I fixed this problem.The device system version is older then the sdk minSdkVersion? I just modified the minSdkVersion from android_L to 19 to target my nexus 4.4.4.

No, it's not.
Attributes are meta-data and stored in binary-form in the compiled assembly (that's also why you can only use simple types in them).
What about using MAX?
That way if no data is found the variable is set to NULL, otherwise the maximum value.
Since you expect either 0 or 1 value, MAX should be OK to use.
v_column my_table.column%TYPE;
select MAX(column) into v_column from my_table where ...;
any
is something specific to TypeScript is explained quite well by alex's answer.
Object
refers to the JavaScript object
type. Commonly used as {}
or sometimes new Object
. Most things in javascript are compatible with the object data type as they inherit from it. But any
is TypeScript specific and compatible with everything in both directions (not inheritance based). e.g. :
var foo:Object;
var bar:any;
var num:number;
foo = num; // Not an error
num = foo; // ERROR
// Any is compatible both ways
bar = num;
num = bar;
I would also vote for Mosty Mostacho's solution with minor modification to his query code:
SELECT a.i, a.j, (
SELECT count(*) from test b where a.j >= b.j AND a.i = b.i
) AS row_number FROM test a
Which will give the same result:
+------+------+------------+
| i | j | row_number |
+------+------+------------+
| 1 | 11 | 1 |
| 1 | 12 | 2 |
| 1 | 13 | 3 |
| 2 | 21 | 1 |
| 2 | 22 | 2 |
| 2 | 23 | 3 |
| 3 | 31 | 1 |
| 3 | 32 | 2 |
| 3 | 33 | 3 |
| 4 | 14 | 1 |
+------+------+------------+
for the table:
+------+------+
| i | j |
+------+------+
| 1 | 11 |
| 1 | 12 |
| 1 | 13 |
| 2 | 21 |
| 2 | 22 |
| 2 | 23 |
| 3 | 31 |
| 3 | 32 |
| 3 | 33 |
| 4 | 14 |
+------+------+
With the only difference that the query doesn't use JOIN and GROUP BY, relying on nested select instead.
Sorting dictionaries by value using comprehensions. I think it's nice as 1 line and no need for functions or lambdas
a = {'b':'foo', 'c':'bar', 'e': 'baz'}
a = {f:a[f] for f in sorted(a, key=a.__getitem__)}
Usage and Lingo:
Real World Example:
Hash & Co., founded in 1803 and lacking any computer technology had a total of 300 filing cabinets to keep the detailed information (the records) for their approximately 30,000 clients. Each file folder were clearly identified with its client number, a unique number from 0 to 29,999.
The filing clerks of that time had to quickly fetch and store client records for the working staff. The staff had decided that it would be more efficient to use a hashing methodology to store and retrieve their records.
To file a client record, filing clerks would use the unique client number written on the folder. Using this client number, they would modulate the hash key by 300 in order to identify the filing cabinet it is contained in. When they opened the filing cabinet they would discover that it contained many folders ordered by client number. After identifying the correct location, they would simply slip it in.
To retrieve a client record, filing clerks would be given a client number on a slip of paper. Using this unique client number (the hash key), they would modulate it by 300 in order to determine which filing cabinet had the clients folder. When they opened the filing cabinet they would discover that it contained many folders ordered by client number. Searching through the records they would quickly find the client folder and retrieve it.
In our real-world example, our buckets are filing cabinets and our records are file folders.
An important thing to remember is that computers (and their algorithms) deal with numbers better than with strings. So accessing a large array using an index is significantly much faster than accessing sequentially.
As Simon has mentioned which I believe to be very important is that the hashing part is to transform a large space (of arbitrary length, usually strings, etc) and mapping it to a small space (of known size, usually numbers) for indexing. This if very important to remember!
So in the example above, the 30,000 possible clients or so are mapped to a smaller space.
The main idea in this is to divide your entire data set into segments as to speed up the actual searching which is usually time consuming. In our example above, each of the 300 filing cabinet would (statistically) contain about 100 records. Searching (regardless the order) through 100 records is much faster than having to deal with 30,000.
You may have noticed that some actually already do this. But instead of devising a hashing methodology to generate a hash key, they will in most cases simply use the first letter of the last name. So if you have 26 filing cabinets each containing a letter from A to Z, you in theory have just segmented your data and enhanced the filing and retrieval process.
Hope this helps,
Jeach!
Just pass your regression model into the following function:
plot_coeffs <- function(mlr_model) {
coeffs <- coefficients(mlr_model)
mp <- barplot(coeffs, col="#3F97D0", xaxt='n', main="Regression Coefficients")
lablist <- names(coeffs)
text(mp, par("usr")[3], labels = lablist, srt = 45, adj = c(1.1,1.1), xpd = TRUE, cex=0.6)
}
Use as follows:
model <- lm(Petal.Width ~ ., data = iris)
plot_coeffs(model)

I faced with the same issue when I tried to send bitmap via Intent and at the same time when it happens I folded the application.
How it described in this article enter link description here it happens when an Activity is in the process of stopping, that means that the Activity was trying to send its saved state Bundles to the system OS for safe keeping for restoration later (after a config change or process death) but that one or more of the Bundles it sent were too large.
I solved it via hack by overriding onSaveInstanceState in my Activity:
@Override
protected void onSaveInstanceState(Bundle outState) {
// super.onSaveInstanceState(outState);
}
and comment call super. It is a dirty hack but it is working perfectly. Bitmap was successfully sent without crashes. Hope this will help someone.

Best, cleanest way is to use a UDF
.
Explanation within the code.
// create some example data...BY DataFrame
// note, third record has an empty string
case class Stuff(a:String,b:Int)
val d= sc.parallelize(Seq( ("a",1),("b",2),
("",3) ,("d",4)).map { x => Stuff(x._1,x._2) }).toDF
// now the good stuff.
import org.apache.spark.sql.functions.udf
// function that returns 0 is string empty
val func = udf( (s:String) => if(s.isEmpty) 0 else 1 )
// create new dataframe with added column named "notempty"
val r = d.select( $"a", $"b", func($"a").as("notempty") )
scala> r.show
+---+---+--------+
| a| b|notempty|
+---+---+--------+
| a| 1| 1111|
| b| 2| 1111|
| | 3| 0|
| d| 4| 1111|

HTML5 defined a window.saveAs(blob, filename)
method. It isn't supported by any browser right now. But there is a compatibility library called FileSaver.js that adds this function to most modern browsers (including Internet Explorer 10+). Internet Explorer 10 supports a navigator.msSaveBlob(blob, filename)
method (MSDN), which is used in FileSaver.js for Internet Explorer support.
I wrote a blog posting with more details about this problem.
You can use a kind of continue
by using a nested Do ... Loop While False
:
'This sample will output 1 and 3 only
Dim i As Integer
For i = 1 To 3: Do
If i = 2 Then Exit Do 'Exit Do is the Continue
Debug.Print i
Loop While False: Next i

In GitLab some branches can be protected. By default only Maintainer/Owner users can commit to protected branches (see permissions docs). master
branch is protected by default - it forces developers to issue merge requests to be validated by project maintainers before integrating them into main code.
You can turn on and off protection on selected branches in Project Settings (where exactly depends on GitLab version - see instructions below).
On the same settings page you can also allow developers to push into the protected branches. With this setting on, protection will be limited to rejecting operations requiring git push --force
(rebase etc.)
Go to project: "Settings" ? "Repository" ? "Expand" on "Protected branches"
I'm not really sure when this change was introduced, screenshots are from 10.3 version.
Now you can select who is allowed to merge or push into selected branches (for example: you can turn off pushes to master
at all, forcing all changes to branch to be made via Merge Requests). Or you can click "Unprotect" to completely remove protection from branch.
Similarly to GitLab 9.3, but no need to click "Expand" - everything is already expanded:
Go to project: "Settings" ? "Repository" ? scroll down to "Protected branches".
Project: "Settings" ? "Protected branches" (if you are at least 'Master' of given project).
Then click on "Unprotect" or "Developers can push":
JavaScript doesn't have a native StringBuffer object, so I'm assuming this is from a library you are using, or a feature of an unusual host environment (i.e. not a browser).
I doubt a library (written in JS) would produce anything faster, although a native StringBuffer object might. The definitive answer can be found with a profiler (if you are running in a browser then Firebug will provide you with a profiler for the JS engine found in Firefox).
I needed to export our security log and wanted the date and time in Coordinated Universal Time. This proved to be a challenge to figure out, but so simple to execute:
wevtutil export-log security c:\users\%username%\SECURITYEVENTLOG-%computername%-$(((get-date).ToUniversalTime()).ToString("yyyyMMddTHHmmssZ")).evtx
The magic code is just this part:
$(((get-date).ToUniversalTime()).ToString("yyyyMMddTHHmmssZ"))
Select Eventname,
count(Eventname) as 'Counts'
INTO #TEMPTABLE
FROM tblevent
where Eventname like 'A%'
Group by Eventname
order by count(Eventname)
Here by using the into clause the table is directly created

PDF2SVG version 6.0 from PDFTron does a reasonable job. It produces OpenType (.otf
) fonts by default. Use --preserve_fontnames
to preserve "the font/font-family naming scheme as obtained from the source file."
PDF2SVG is a commercial product, but you can download a free demo executable (which includes watermarks on the SVG output but doesn't otherwise restrict usage). There may be other PDFTron products that also extract fonts, but I only recently discovered PDF2SVG myself.
At least in Postgres you can use the following statement:
SELECT EntityID, EntityName, EntityProfile IS NOT NULL AS HasProfile FROM Entity
If you don't want indention in your list and also don't care about or don't want bullets, there is the CSS-free option of using a "definition list" (HTML 4.01) or "description list" (HTML 5). Use only the non-indenting definition <dt>
tags, but not the indenting description <dd>
tags, neither of which produces a bullet.
<dl>
<dt>Item 1</dt>
<dt>Item 2</dt>
<dt>Item 3</dt>
</dl>
The output looks like this:
Item 1
Item 2
Item 3
my_list = sorted(dict.items(), key=lambda x: x[1])
I don't think you need/want the timeout.
onhover (hover) would be defined as the time period while "over" something. IMHO
onmouseover = start...
onmouseout = ...end
For the record I've done some stuff with this to "fake" the hover event in IE6. It was rather expensive and in the end I ditched it in favor of performance.
I had some issues with the MouseDown part of this, but here is some code that might get your started.

git pull
= git fetch
+ git merge origin/branch
git pull
and git pull origin branch
only differ in that the latter will only "update" origin/branch and not all origin/* as git pull
does.
git pull origin/branch
will just not work because it's trying to do a git fetch origin/branch
which is invalid.
Question related: git fetch + git merge origin/master vs git pull origin/master
The existing answers will fail if the string is empty or only has one character. Options:
String substring = str.length() > 2 ? str.substring(str.length() - 2) : str;
or
String substring = str.substring(Math.max(str.length() - 2, 0));
That's assuming that str
is non-null, and that if there are fewer than 2 characters, you just want the original string.
If you need to log an error to Apache error log you can try this:
error_log( print_r($multidimensionalarray, TRUE) );
1) When to use include directive ?
To prevent duplication of same output logic across multiple jsp's of the web app ,include mechanism is used ie.,to promote the re-usability of presentation logic include directive is used
<%@ include file="abc.jsp" %>
when the above instruction is received by the jsp engine,it retrieves the source code of the abc.jsp and copy's the same inline in the current jsp. After copying translation is performed for the current page
Simply saying it is static instruction to jsp engine ie., whole source code of "abc.jsp" is copied into the current page
2) When to use include action ?
include tag doesn't include the source code of the included page into the current page instead the output generated at run time by the included page is included into the current page response
include tag functionality is similar to that of include mechanism of request dispatcher of servlet programming
include tag is run-time instruction to jsp engine ie., rather copying whole code into current page a method call is made to "abc.jsp" from current page
awk, sed, pipe, that's heavy
set `cat /etc/*release`; echo $1
This is a follow up to the answer given by @EricWoodruff.
You could use netInfo
's getExtraInfo()
to get wifi SSID.
if (WifiManager.NETWORK_STATE_CHANGED_ACTION.equals (action)) {
NetworkInfo netInfo = intent.getParcelableExtra (WifiManager.EXTRA_NETWORK_INFO);
if (ConnectivityManager.TYPE_WIFI == netInfo.getType ()) {
String ssid = info.getExtraInfo()
Log.d(TAG, "WiFi SSID: " + ssid)
}
}
If you are not using BroadcastReceiver check this answer to get SSID using Context

Your original problem is that pip cannot write the logs to the folder.
IOError: [Errno 13] Permission denied: '/Users/markwalker/Library/Logs/pip.log'
You need to cd into a folder in which the process invoked can write like /tmp
so a cd /tmp
and re invoking the command will probably work but is not what you want.
BUT actually for this particular case (you not wanting to use sudo
for installing python packages) and no need for global package installs you can use the --user
flag like this :
pip install --user <packagename>
and it will work just fine.
I assume you have a one user python python installation and do not want to bother with reading about virtualenv (which is not very userfriendly) or pipenv.
As some people in the comments section have pointed out the next approach is not a very good idea unless you do not know what to do and got stuck:
Another approach for global packages like in your case you want to do something like :
chown -R $USER /Library/Python/2.7/site-packages/
or more generally
chown -R $USER <path to your global pip packages>
Use below code to generate files on fly..
<? //Generate text file on the fly
header("Content-type: text/plain");
header("Content-Disposition: attachment; filename=savethis.txt");
// do your Db stuff here to get the content into $content
print "This is some text...\n";
print $content;
?>
To get a position of an element in a vector knowing an iterator pointing to the element, simply subtract v.begin()
from the iterator:
ptrdiff_t pos = find(Names.begin(), Names.end(), old_name_) - Names.begin();
Now you need to check pos
against Names.size()
to see if it is out of bounds or not:
if(pos >= Names.size()) {
//old_name_ not found
}
vector iterators behave in ways similar to array pointers; most of what you know about pointer arithmetic can be applied to vector iterators as well.
Starting with C++11 you can use std::distance
in place of subtraction for both iterators and pointers:
ptrdiff_t pos = distance(Names.begin(), find(Names.begin(), Names.end(), old_name_));
Real simple. You just need to have the string 'selected' added to the right option. In the following code, ${myBean.foo == val ? 'selected' : ' '} will add the string 'selected' if the option's value is the same as the bean value;
<select name="foo" id="foo" value="${myBean.foo}">
<option value="">ALL</option>
<c:forEach items="${fooList}" var="val">
<option value="${val}" ${myBean.foo == val ? 'selected' : ' '}><c:out value="${val}" ></c:out></option>
</c:forEach>
</select>
This is super late, but I just ran into this problem. In my own project I used the following to check if a string was in an array:
["a","b"].includes('a') // true
["a","b"].includes('b') // true
["a","b"].includes('c') // false
This way you can take a predefined array and check if it contains a string:
var parameters = ['a','b']
parameters.includes('a') // true
I know this is older, but wanted to contribute another possibly solution.
If you want to keep the project location, as I did, I found that copying the .project file from another project into the project's directory, then editing the .project file to name it properly, then choosing the Import Existing Projects into Workspace option worked for me.
In Windows, I used a file monitor to see what Eclipse was doing, and it was simply erroring out for some unknown reason when trying to create the .project file. So, I did that manually and it worked for me.
On parent DIV:

It can be done with a little bit of extra overhead.
Simply wrap your link in a div, and separate the animation.
the html ..
<div class="animateOnce">
<a class="animateOnHover">me!</a>
</div>
.. and the css ..
.animateOnce {
animation: splash 1s normal forwards ease-in-out;
}
.animateOnHover:hover {
animation: hover 1s infinite alternate ease-in-out;
}
Java enums don't have the same kind of enum-to-int mapping that they do in C++.
That said, all enums have a values
method that returns an array of possible enum values, so
MyEnum enumValue = MyEnum.values()[x];
should work. It's a little nasty and it might be better to not try and convert from int
s to Enum
s (or vice versa) if possible.
To get the cheapest product in each category, you use the MIN() function in a correlated subquery as follows:
SELECT categoryid,
productid,
productName,
unitprice
FROM products a WHERE unitprice = (
SELECT MIN(unitprice)
FROM products b
WHERE b.categoryid = a.categoryid)
The outer query scans all rows in the products table and returns the products that have unit prices match with the lowest price in each category returned by the correlated subquery.

This test is using a system partition. Results for a non-system partition are a bit better.

How about something like this? Note that myDelimitedString may be null if myEnumerable is empty.
IEnumerator enumerator = myEnumerable.GetEnumerator();
string myDelimitedString;
string current = null;
if( enumerator.MoveNext() )
current = (string)enumerator.Current;
while( null != current)
{
current = (string)enumerator.Current; }
myDelimitedString += current;
if( enumerator.MoveNext() )
myDelimitedString += DELIMITER;
else
break;
}
in fact, you can, but not that way.
Sub MySub( Optional Byval Counter as Long=1 , Optional Byval Events as Boolean= True)
'code...
End Sub
And you can set the variables differently when calling the sub, or let them at their default values.
you have to set the tableName you want to your dtimage that is for instance
dtImage.TableName="mydtimage";
if(!ds.Tables.Contains(dtImage.TableName))
ds.Tables.Add(dtImage);
it will be reflected in dataset because dataset is a container of your datatable dtimage and you have a reference on your dtimage
Here is the code form https://github.com/ssnau/xkit/blob/master/util/is-promise.js

Without root, you can use debug proxies like Charlesproxy&Co.
Consider using Windmill , although Windmill probably cant do that many threads.
You could do it with a hand rolled Python script on 5 machines, each one connecting outbound using ports 40000-60000, opening 100,000 port connections.
Also, it might help to do a sample test with a nicely threaded QA app such as OpenSTA in order to get an idea of how much each server can handle.
Also, try looking into just using simple Perl with the LWP::ConnCache class. You'll probably get more performance (more connections) that way.
You get this if itemdescription is shorter than 38 characters

In AVD manager, after setting up AVD using a target with Google APIs
, on run was getting error.
Detail showed: "AVD Unknown target 'Google Inc.:Google APIs:...... "
During install (on Win7 system) I had chosen a SDK directory location, instead of accepting C:\Users\...
I'd then added that directory to environment variable 'path'
Command line: android list targets did show a couple of Google apis.
Setting ANDROID_SDK_HOME
to my install path fixed the avd run error.
For editing this is possible in nano

I had a same problem and the same error was showing up. my TNSNAMES:ORA file was also good to go but apparently there was a problem due to firewall blocking the access. SO a good tip would be to make sure that firewall is not blocking the access to the datasource.
You can also try to get the column names from panda data frame that returns columnn name as well dtype. here i'll read csv file from https://mlearn.ics.uci.edu/databases/autos/imports-85.data but you have define header that contain columns names.

url="https://mlearn.ics.uci.edu/databases/autos/imports-85.data"
df=pd.read_csv(url,header = None)
headers=["symboling","normalized-losses","make","fuel-type","aspiration","num-of-doors","body-style",

Python opens files almost in the same way as in C:
r+
Open for reading and writing. The stream is positioned at the beginning of the file.
a+
Open for reading and appending (writing at end of file). The file is created if it does not exist. The initial file position for reading is at the beginning of the file, but output is appended to the end of the file (but in some Unix systems regardless of the current seek position).
public class Test {
public class A {}
public class B extends A {}
public class C extends B {}
public void testCoVariance(List<? extends B> myBlist) {
B b = new B();
C c = new C();
myBlist.add(b); // does not compile
myBlist.add(c); // does not compile
A a = myBlist.get(0);
}
public void testContraVariance(List<? super B> myBlist) {
B b = new B();
C c = new C();
myBlist.add(b);
myBlist.add(c);
A a = myBlist.get(0); // does not compile
}
}
To center align an unordered list, you need to use the CSS text align property. In addition to this, you also need to put the unordered list inside the div element.
Now, add the style to the div class and use the text-align property with center as its value.
See the below example.
<style>
.myDivElement{
text-align:center;
}
.myDivElement ul li{
display:inline;
}
</style>
<div class="myDivElement">
<ul>
<li>Home</li>
<li>About</li>
<li>Gallery</li>
<li>Contact</li>
</ul>
</div>

I won't quote the entire page but the whole manual on optimisation is available here: http://gcc.gnu.org/onlinedocs/gcc-4.4.3/gcc/Optimize-Options.html#Optimize-Options
From the sounds of it you want at least -O0
, the default, and:
-fmudflap -fmudflapth -fmudflapir
For front-ends that support it (C and C++), instrument all risky pointer/array dereferencing operations, some standard library string/heap functions, and some other associated constructs with range/validity tests. Modules so instrumented should be immune to buffer overflows, invalid heap use, and some other classes of C/C++ programming errors. The instrumentation relies on a separate runtime library (libmudflap), which will be linked into a program if -fmudflap is given at link time. Run-time behavior of the instrumented program is controlled by the MUDFLAP_OPTIONS environment variable. See env MUDFLAP_OPTIONS=-help a.out for its options.

Unless there is a single row in the ASSIGNMENT
table and ASSIGNMENT_20081120
is a local PL/SQL variable of type ASSIGNMENT%ROWTYPE
, this is not what you want.
Assuming you are trying to create a new table and copy the existing data to that new table
CREATE TABLE assignment_20081120
AS
SELECT *
FROM assignment
The bottom statement is equivalent to:
.half {
flex-grow: 0;
flex-shrink: 0;
flex-basis: 50%;
}
Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.
Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.
I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)
I was looking for a similar thing. My problem was to find the last column based on row 5 and then select 3 columns before including the last column.
Dim lColumn As Long
lColumn = ActiveSheet.Cells(5,Columns.Count).End(xlToLeft).Column
MsgBox ("The last used column is: " & lColumn)
Range(Columns(lColumn - 3), Columns(lColumn)).Select
Message box is optional as it is more of a control check. If you want to select the columns after the last column then you simply reverse the range selection
Dim lColumn As Long
lColumn = ActiveSheet.Cells(5,Columns.Count).End(xlToLeft).Column
MsgBox ("The last used column is: " & lColumn)
Range(Columns(lColumn), Columns(lColumn + 3)).Select
You can save the current scroll amount and then set it later:
var tempScrollTop = $(window).scrollTop();
..//Your code
$(window).scrollTop(tempScrollTop);
The error should be finally fixed as of ADT 17/Tools r17 preview releases! At least some instances of it, if not all.
That should work, you may need a space after the commas.
Also, the function you call afterwards must support an array of objects, and not just a singleton object.
I suggest using one of the exchange
methods that accepts an HttpEntity
for which you can also set the HttpHeaders
. (You can also specify the HTTP method you want to use.)
For example,
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
HttpEntity<String> entity = new HttpEntity<>("body", headers);
restTemplate.exchange(url, HttpMethod.POST, entity, String.class);
I prefer this solution because it's strongly typed, ie. exchange
expects an HttpEntity
.
However, you can also pass that HttpEntity
as a request
argument to postForObject
.
HttpEntity<String> entity = new HttpEntity<>("body", headers);
restTemplate.postForObject(url, entity, String.class);
This is mentioned in the RestTemplate#postForObject
Javadoc.
The
request
parameter can be aHttpEntity
in order to add additional HTTP headers to the request.
As a response to your question: "i want to reset all the data and keep last 30 days inside the table."
you can create an event. Check https://dev.mysql.com/doc/refman/5.7/en/event-scheduler.html
For example:
CREATE EVENT DeleteExpiredLog
ON SCHEDULE EVERY 1 DAY
DO
DELETE FROM log WHERE date < DATE_SUB(NOW(), INTERVAL 30 DAY);
Will run a daily cleanup in your table, keeping the last 30 days data available
How to print:
NSLog(@"Something To Print");
Or
NSString * someString = @"Something To Print";

NSLog(@"%i", someInt);
NSLog(@"%f", someFloat);
/// etc...
Can you show it in phone?
Not by default, but you could set up a display to show you.
print("Print this string")
print("Print this \(variable)")
print("Print this ", variable)

This happens when you are trying to run application on emulator. Emulator does not have shared google maps library.
On performance you keep focusing on select.
Shared does not block reads.
Shared lock blocks update.
If you have hundreds of shared locks it is going to take an update a while to get an exclusive lock as it must wait for shared locks to clear.
By default a select (read) takes a shared lock.
Shared (S) locks allow concurrent transactions to read (SELECT) a resource.
A shared lock as no effect on other selects (1 or a 1000).
The difference is how the nolock versus shared lock effects update or insert operation.
No other transactions can modify the data while shared (S) locks exist on the resource.
A shared lock blocks an update!
But nolock does not block an update.
This can have huge impacts on performance of updates. It also impact inserts.
Dirty read (nolock) just sounds dirty. You are never going to get partial data. If an update is changing John to Sally you are never going to get Jolly.
I use shared locks a lot for concurrency. Data is stale as soon as it is read. A read of John that changes to Sally the next millisecond is stale data. A read of Sally that gets rolled back John the next millisecond is stale data. That is on the millisecond level. I have a dataloader that take 20 hours to run if users are taking shared locks and 4 hours to run is users are taking no lock. Shared locks in this case cause data to be 16 hours stale.
Don't use nolocks wrong. But they do have a place. If you are going to cut a check when a byte is set to 1 and then set it to 2 when the check is cut - not a time for a nolock.
This can be achieved using div. It can be done with table too. But i always prefer div.
<body id="doc-body" style="width: 100%; height: 100%; overflow: hidden; position: fixed" onload="InitApp()">
<div>
<!--If you don't need header background color you don't need this div.-->
<div id="div-header-hack" style="height: 20px; position: absolute; background-color: gray"></div>
<div id="div-header" style="position: absolute; top: 0px; overflow: hidden; height: 20px; background-color: gray">
</div>
<div id="div-item" style="position: absolute; top: 20px; overflow: auto" onscroll="ScrollHeader()">

Javascript:
please refer jsFiddle for this part. Else this answer becomes very lengthy.
And to complement Rich's recursive answer, a non-recursive method.
Public Sub NonRecursiveMethod()
Dim fso, oFolder, oSubfolder, oFile, queue As Collection
Set fso = CreateObject("Scripting.FileSystemObject")
Set queue = New Collection
queue.Add fso.GetFolder("your folder path variable") 'obviously replace
Do While queue.Count > 0
Set oFolder = queue(1)
queue.Remove 1 'dequeue
'...insert any folder processing code here...
For Each oSubfolder In oFolder.SubFolders
queue.Add oSubfolder 'enqueue
Next oSubfolder
For Each oFile In oFolder.Files
'...insert any file processing code here...
Next oFile
Loop
End Sub
You can use a queue for FIFO behaviour (shown above), or you can use a stack for LIFO behaviour which would process in the same order as a recursive approach (replace Set oFolder = queue(1)
with Set oFolder = queue(queue.Count)
and replace queue.Remove(1)
with queue.Remove(queue.Count)
, and probably rename the variable...)
I use this to sort the users, so the permitted hosts are more easy to spot:
mysql> SELECT User,Host FROM mysql.user ORDER BY User,Host;
You are using a local path. Is that really what you want? If it is, you need to use the file:///
prefix:
file:///H:/media/css/static/img/sprites/buttons-v3-10.png
obviously, this will work only on your local computer.
Also, in many modern browsers, this works only if the page itself is also on a local file path. Addressing local files from remote (http://
, https://
) pages has been widely disabled due to security reasons.
I know my answer is late to the party. But the way i solved is bit different than all the answers.
I had a situation, i need to clone a row in a table except few columns. Those few will have new values. This process should support automatically for future changes to the table. This implies, clone the record without specifying any column names.
My approach is to,
declare @columnsToCopyValues varchar(max), @query varchar(max)
SET @columnsToCopyValues = ''
--Get all the columns execpt Identity columns and Other columns to be excluded. Say IndentityColumn, Column1, Column2
Select @columnsToCopyValues = @columnsToCopyValues + [name] + ', ' from sys.columns c where c.object_id = OBJECT_ID('YourTableName') and name not in ('IndentityColumn','Column1','Column2')
Select @columnsToCopyValues = SUBSTRING(@columnsToCopyValues, 0, LEN(@columnsToCopyValues))
print @columnsToCopyValues
Select @query = CONCAT('insert into YourTableName (',@columnsToCopyValues,', Column1, Column2) select ', @columnsToCopyValues, ',''Value1'',''Value2'',', ' from YourTableName where IndentityColumn =''' , @searchVariable,'''')
print @query
exec (@query)
You need to add C:\xampp\php
to your PATH Environment Variable
, Only after then you would be able to execute php
command line from outside php_home
.
$page='one'
should occur before you require_once()
not after. After is too late- the code has already been required, and $nav
has already been defined.
You should use include('header.php');
and include('footer.php');
instead of setting a $nav
variable early on. That increases flexibility.
Make more functions. Something like this really makes things easier to follow:
function maybe($x,$y){return $x?$y:'';}
function aclass($k){return " class=\"$k\" "; }
then you can write your "condition" like this:
<a href="..." <?= maybe($page=='one',aclass('active')) ?>> ....
Actually, you can, even though accepted answer saying that you can't.

Assuming SQL Server 2000, the following StackOverflow question should address your problem.
If using SQL Server 2005/2008, you can use the following code (taken from here):
select cast(replace(cast(myntext as nvarchar(max)),'find','replace') as ntext)
from myntexttable
If you are OK with using ES6 syntax, I find that the cleanest way to do this, as noted here and here is:
const data = {
item1: { key: 'sdfd', value:'sdfd' },
item2: { key: 'sdfd', value:'sdfd' },
item3: { key: 'sdfd', value:'sdfd' }
};
const { item2, ...newData } = data;
Now, newData
contains:
{
item1: { key: 'sdfd', value:'sdfd' },
item3: { key: 'sdfd', value:'sdfd' }
};
Or, if you have the key stored as a string:
const key = 'item2';
const { [key]: _, ...newData } = data;
In the latter case, [key]
is converted to item2
but since you are using a const
assignment, you need to specify a name for the assignment. _
represents a throw away value.
More generally:
const { item2, ...newData } = data; // Assign item2 to item2
const { item2: someVarName, ...newData } = data; // Assign item2 to someVarName
const { item2: _, ...newData } = data; // Assign item2 to _
const { ['item2']: _, ...newData } = data; // Convert string to key first, ...
Not only does this reduce your operation to a one-liner but it also doesn't require you to know what the other keys are (those that you want to preserve).
A simple utility function would look like this:
function removePropFromObject(obj, prop) {
const { [prop]: _, ...rest } = obj
return { ...rest }
}
Arrays in PHP can have Key Value structure.

It is correct, but perhaps not useful.
As there is nothing to wait on – no calls to blocking APIs which could operate asynchronously – then you are setting up structures to track asynchronous operation (which has overhead) but then not making use of that capability.
For example, if the service layer was performing DB operations with Entity Framework which supports asynchronous calls:
public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
using (db = myDBContext.Get()) {
var list = await db.Countries.Where(condition).ToListAsync();
return list;
}
}
You would allow the worker thread to do something else while the db was queried (and thus able to process another request).
Await tends to be something that needs to go all the way down: it is very hard to retro-fit into an existing system.
Your calls are made recursively which pushes functions on to the stack infinitely that causes max call stack exceeded error due to recursive behavior. Instead try using setTimeout which is a callback.
Also based on your markup your selector is wrong. it should be #advisersDiv
function fadeIn() {
$('#pulseDiv').find('div#advisersDiv').delay(400).addClass("pulse");
setTimeout(fadeOut,1); //<-- Provide any delay here
};

This can be done using ServerSocket, same as on JavaSE. This class is available on Android. android.permission.INTERNET
is required.
The only more tricky part, you need a separate thread wait on the ServerSocket, servicing sub-sockets that come from its accept
method. You also need to stop and resume this thread as needed. The simplest approach seems to kill the waiting thread by closing the ServerSocket.
If you only need a server while your activity is on the top, starting and stopping ServerSocket thread can be rather elegantly tied to the activity life cycle methods. Also, if the server has multiple users, it may be good to service requests in the forked threads. If there is only one user, this may not be necessary.
If you need to tell the user on which IP is the server listening,use NetworkInterface.getNetworkInterfaces(), this question may tell extra tricks.
Finally, here there is possibly the complete minimal Android server that is very short, simple and may be easier to understand than finished end user applications, recommended in other answers.
This is the Best of all methods i came across
Clone just the repository's .git folder (excluding files as they are already in existing-dir
) into an empty temporary directory
git clone --no-checkout repo-path-to-clone existing-dir/existing-dir.tmp
//might want --no-hardlinks for cloning local repoMove the .git folder to the directory with the files.
This makes existing-dir
a git repo.
mv existing-dir/existing-dir.tmp/.git existing-dir/
Delete the temporary directory
rmdir existing-dir/existing-dir.tmp
cd existing-dir
Git thinks all files are deleted, this reverts the state of the repo to HEAD.
WARNING: any local changes to the files will be lost.
git reset --mixed HEAD
To send to both remote with one command, you can create a alias for it:
git config alias.pushall '!git push origin devel && git push github devel'
With this, when you use the command git pushall
, it will update both repositories.
If you want to escape user input in a variable you can do like below within SQL
Set @userinput = replace(@userinput,'''','''''')
The @userinput will be now escaped with an extra single quote for every occurance of a quote
Tried npm install mongoose --msvs_version=2012, if you have multiple Visual installed, it worked for me
There are a lot of right answers here depending on what you are trying to accomplish; here's my attempt at providing a comprehensive answer:
Both the Request
and Response
objects contain Cookies
properties, which are HttpCookieCollection
objects.
Request.Cookies:
null
value.Response.Cookies:
Request.Cookies
collection, it will be added (but if the Request.Cookies
object already contains a cookie with the same key, and even if it's value is stale, it will not be updated to reflect the changes from the newly-created cookie in the Response.Cookies
collection.Solutions
If you want to check for the existence of a cookie from the client, do one of the following
Request.Cookies["COOKIE_KEY"] != null
Request.Cookies.Get("COOKIE_KEY") != null
Request.Cookies.AllKeys.Contains("COOKIE_KEY")
If you want to check for the existence of a cookie that has been added by the server during the current request, do the following:
Response.Cookies.AllKeys.Contains("COOKIE_KEY")
(see here)Attempting to check for a cookie that has been added by the server during the current request by one of these methods...
Response.Cookies["COOKIE_KEY"] != null
Response.Cookies.Get("COOKIE_KEY") != null
(see here)...will result in the creation of a cookie in the Response.Cookies
collection and the state will evaluate to true
.
With the release of the latest Android Support Library (rev 22.2.0) we've got a Design Support Library and as part of this a new view called NavigationView. So instead of doing everything on our own with the ScrimInsetsFrameLayout
and all the other stuff we simply use this view and everything is done for us.
Add the Design Support Library
to your build.gradle
file
dependencies {
// Other dependencies like appcompat
compile 'com.android.support:design:22.2.0'
}
Add the NavigationView
to your DrawerLayout
:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"> <!-- this is important -->
<!-- Your contents -->
<android.support.design.widget.NavigationView
android:id="@+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="@menu/navigation_items" /> <!-- The items to display -->
</android.support.v4.widget.DrawerLayout>
Create a new menu-resource in /res/menu
and add the items and icons you wanna display:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="@+id/nav_home"
android:icon="@drawable/ic_action_home"
android:title="Home" />
<item
android:id="@+id/nav_example_item_1"
android:icon="@drawable/ic_action_dashboard"
android:title="Example Item #1" />
</group>
<item android:title="Sub items">
<menu>
<item
android:id="@+id/nav_example_sub_item_1"
android:title="Example Sub Item #1" />
</menu>
</item>
</menu>
Init the NavigationView and handle click events:
public class MainActivity extends AppCompatActivity {
NavigationView mNavigationView;
DrawerLayout mDrawerLayout;
// Other stuff
private void init() {
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mNavigationView = (NavigationView) findViewById(R.id.navigation_view);
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
mDrawerLayout.closeDrawers();
menuItem.setChecked(true);
switch (menuItem.getItemId()) {
case R.id.nav_home:
// TODO - Do something
break;
// TODO - Handle other items
}
return true;
}
});
}
}
Be sure to set android:windowDrawsSystemBarBackgrounds
and android:statusBarColor
in values-v21
otherwise your Drawer won`t be displayed "under" the StatusBar
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Other attributes like colorPrimary, colorAccent etc. -->
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
</style>
Add a Header to the NavigationView. For this simply create a new layout and add app:headerLayout="@layout/my_header_layout"
to the NavigationView.
colorPrimary
attributetextColorPrimary
attributetextColorSecondary
attributeYou can also check the example app by Chris Banes which highlights the NavigationView along with the other new views that are part of the Design Support Library (like the FloatingActionButton, TextInputLayout, Snackbar, TabLayout etc.)
I got so fed up with checking for null and empty strings specifically, that I now usually just write and call a small function to do it for me.
/**
* Test if the given value equals null or the empty string.
*
* @param {string} value
**/
const isEmpty = (value) => value === null || value === '';
// Test:
isEmpty(''); // true
isEmpty(null); // true
isEmpty(1); // false
isEmpty(0); // false
isEmpty(undefined); // false
Here's a simpler Python implementation of @varun-vohra answer:
def apportion_pcts(pcts, total):
proportions = [total * (pct / 100) for pct in pcts]
apportions = [math.floor(p) for p in proportions]
remainder = total - sum(apportions)
remainders = [(i, p - math.floor(p)) for (i, p) in enumerate(proportions)]
remainders.sort(key=operator.itemgetter(1), reverse=True)
for (i, _) in itertools.cycle(remainders):
if remainder == 0:
break
else:
apportions[i] += 1
remainder -= 1
return apportions
You need math
, itertools
, operator
.
There's no direct way to do it yet, unfortunately, but there are a couple indirect ways:
[dt.year for dt in dates.astype(object)]
or
[datetime.datetime.strptime(repr(d), "%Y-%m-%d %H:%M:%S").year for d in dates]
both inspired by the examples here.
Both of these work for me on Numpy 1.6.1. You may need to be a bit more careful with the second one, since the repr() for the datetime64 might have a fraction part after a decimal point.
In Java, Dates are internally represented in UTC milliseconds since the epoch (so timezones are not taken into account, that's why you get the same results, as getTime()
gives you the mentioned milliseconds).
In your solution:
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
long gmtTime = cSchedStartCal.getTime().getTime();
long timezoneAlteredTime = gmtTime + TimeZone.getTimeZone("Asia/Calcutta").getRawOffset();
Calendar cSchedStartCal1 = Calendar.getInstance(TimeZone.getTimeZone("Asia/Calcutta"));
cSchedStartCal1.setTimeInMillis(timezoneAlteredTime);
you just add the offset from GMT to the specified timezone ("Asia/Calcutta" in your example) in milliseconds, so this should work fine.
Another possible solution would be to utilise the static fields of the Calendar
class:
//instantiates a calendar using the current time in the specified timezone
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
//change the timezone
cSchedStartCal.setTimeZone(TimeZone.getTimeZone("Asia/Calcutta"));
//get the current hour of the day in the new timezone
cSchedStartCal.get(Calendar.HOUR_OF_DAY);
Refer to stackoverflow.com/questions/7695859/ for a more in-depth explanation.

try
if ! grep -q sysa /etc/passwd ; then
grep
returns true
if it finds the search target, and false
if it doesn't.
So NOT false
== true
.
if
evaluation in shells are designed to be very flexible, and many times doesn't require chains of commands (as you have written).
Also, looking at your code as is, your use of the $( ... )
form of cmd-substitution is to be commended, but think about what is coming out of the process. Try echo $(cat /etc/passwd | grep "sysa")
to see what I mean. You can take that further by using the -c
(count) option to grep and then do if ! [ $(grep -c "sysa" /etc/passwd) -eq 0 ] ; then
which works but is rather old school.
BUT, you could use the newest shell features (arithmetic evaluation) like
if ! (( $(grep -c "sysa" /etc/passwd) == 0 )) ; then ...`
which also gives you the benefit of using the c-lang based comparison operators, ==,<,>,>=,<=,%
and maybe a few others.
In this case, per a comment by Orwellophile, the arithmetic evaluation can be pared down even further, like
if ! (( $(grep -c "sysa" /etc/passwd) )) ; then ....
OR
if (( ! $(grep -c "sysa" /etc/passwd) )) ; then ....
Finally, there is an award called the Useless Use of Cat (UUOC)
. :-) Some people will jump up and down and cry gothca! I'll just say that grep
can take a file name on its cmd-line, so why invoke extra processes and pipe constructions when you don't have to? ;-)
I hope this helps.
For n arrays, you can get the union like so.
function union(arrays) {
return new Set(arrays.flat()).keys();
};
I was encountering the same problem.
I had a Tooltip
component that was receiving showTooltip
prop, that I was updating on Parent
component based on an if
condition, it was getting updated in Parent
component but Tooltip
component was not rendering.
const Parent = () => {
let showTooltip = false;
if(....){ showTooltip = true; }
return(
<Tooltip showTooltip={showTooltip}></Tooltip>
)
}
The mistake I was doing is to declare showTooltip
as a let.
I realized what I was doing wrong I was violating the principles of how rendering works, Replacing it with hooks did the job.
const [showTooltip, setShowTooltip] = React.useState<boolean>(false);

I think you are looking for this function:
http://doc.qt.io/qt-5/qdatetime.html#toTime_t
uint QDateTime::toTime_t () const
Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, > Coordinated Universal Time (Qt::UTC).
On systems that do not support time zones, this function will behave as if local time were Qt::UTC.
See also setTime_t().

To store the array values in cookie, first you need to convert them to string, so here is some options.
Storing code
setcookie('your_cookie_name', json_encode($info), time()+3600);
Reading code
$data = json_decode($_COOKIE['your_cookie_name'], true);
JSON can be good choose also if you need read cookie in front end with JavaScript.
Actually you can use any encrypt_array_to_string
/decrypt_array_from_string
methods group that will convert array to string and convert string back to same array.
For example you can also use explode
/implode
for array of integers.
From PHP.net
Do not pass untrusted user input to unserialize().
- Anything that coming by HTTP including cookies is untrusted!
References related to security
setcookie('my_array[0]', 'value1' , time()+3600);
setcookie('my_array[1]', 'value2' , time()+3600);
setcookie('my_array[2]', 'value3' , time()+3600);
And after if you will print $_COOKIE
variable, you will see the following
echo '<pre>';
print_r( $_COOKIE );
die();
Array ( [my_array] => Array ( [0] => value1 [1] => value2 [2] => value3 ) )
This is documented PHP feature.
From PHP.net
Cookies names can be set as array names and will be available to your PHP scripts as arrays but separate cookies are stored on the user's system.
Oracle's free SQL Developer will do this:
http://www.oracle.com/technetwork/developer-tools/sql-developer/overview/index.html
You just find your table, right-click on it and choose Export Data->Insert
This will give you a file with your insert statements. You can also export the data in SQL Loader format as well.
For best performance, here is what I wrote :
(see execution plan)
DELETE FROM your_table
WHERE rowid IN
(select t1.rowid from your_table t1
LEFT OUTER JOIN (
SELECT MIN(rowid) as rowid, column1,column2, column3
FROM your_table
GROUP BY column1, column2, column3
) co1 ON (t1.rowid = co1.rowid)
WHERE co1.rowid IS NULL
);
Does the job a lot cleaner than parseInt in my opinion, Use the +operator
var s = '';
console.log(+s);
var s = '1024'
+s
1024
s = 0
+s

s = -1
+s

s = ''

Use Platform.runLater(...)
for quick and simple operations and Task
for complex and big operations .
Example: Why Can't we use Platform.runLater(...)
for long calculations (Taken from below reference).
Problem: Background thread which just counts from 0 to 1 million and update progress bar in UI.
Code using Platform.runLater(...)
:
final ProgressBar bar = new ProgressBar();
new Thread(new Runnable() {
@Override public void run() {
for (int i = 1; i <= 1000000; i++) {
final int counter = i;
Platform.runLater(new Runnable() {
@Override public void run() {
bar.setProgress(counter / 1000000.0);
}
});
}
}).start();
This is a hideous hunk of code, a crime against nature (and programming in general). First, you’ll lose brain cells just looking at this double nesting of Runnables. Second, it is going to swamp the event queue with little Runnables — a million of them in fact. Clearly, we needed some API to make it easier to write background workers which then communicate back with the UI.
Code using Task :
Task task = new Task<Void>() {
@Override public Void call() {
static final int max = 1000000;
for (int i = 1; i <= max; i++) {
updateProgress(i, max);
}
return null;
}
};
ProgressBar bar = new ProgressBar();
bar.progressProperty().bind(task.progressProperty());
new Thread(task).start();
it suffers from none of the flaws exhibited in the previous code

You can use SoapUI: http://www.soapui.org/ This is a generally handy program. Make a new project, connect to the WSDL link, then right click on the project and say "Show interface viewer". Under "Schemas" on the left you can see the XSD.
SoapUI can do many things though!
If your app for some reason crashes without good stacktrace. Try debug it from first line, and go line by line until crash. Then you will have answer, which line is causing you trouble. Proably you could then wrapp it into try catch block and print error output.
In addition to the answers above, you could use a small extension method:
public static class Extensions
{
public static void Run(this string fileName,
string workingDir=null, params string[] arguments)
{
using (var p = new Process())
{
var args = p.StartInfo;
args.FileName = fileName;
if (workingDir!=null) args.WorkingDirectory = workingDir;
if (arguments != null && arguments.Any())
args.Arguments = string.Join(" ", arguments).Trim();
else if (fileName.ToLowerInvariant() == "explorer")
args.Arguments = args.WorkingDirectory;
p.Start();
}
}
}
and use it like so:
// open explorer window with given path
"Explorer".Run(path);
// open a shell (remanins open)
"cmd".Run(path, "/K");
In matplotlib a color map isn't a list, but it contains the list of its colors as colormap.colors
. And the module matplotlib.colors
provides a function ListedColormap()
to generate a color map from a list. So you can reverse any color map by doing
colormap_r = ListedColormap(colormap.colors[::-1])
I usually use keys
and I can't think of the last time I used or read a use of each
.
Don't forget about map
, depending on what you're doing in the loop!
map { print "$_ => $hash{$_}\n" } keys %hash;
And, in my case, I mistakenly define my two different columns as identities on DbContext configurations like below,
builder.HasKey(e => e.HistoryId).HasName("HistoryId");
builder.Property(e => e.Id).UseSqlServerIdentityColumn(); //History Id should use identity column in this example
When I correct it like below,
builder.HasKey(e => e.HistoryId).HasName("HistoryId");
builder.Property(e => e.HistoryId).UseSqlServerIdentityColumn();
I have also got rid of this error.
The correct way for checking the visibility of an element with Protractor is to call the isDisplayed
method. You should be careful though since isDisplayed
does not return a boolean, but rather a promise
providing the evaluated visibility. I've seen lots of code examples that use this method wrongly and therefore don't evaluate its actual visibility.
Example for getting the visibility of an element:
element(by.className('your-class-name')).isDisplayed().then(function (isVisible) {
if (isVisible) {
// element is visible
} else {
// element is not visible
}
});
However, you don't need this if you are just checking the visibility of the element (as opposed to getting it) because protractor patches Jasmine expect() so it always waits for promises to be resolved. See github.com/angular/jasminewd
So you can just do:
expect(element(by.className('your-class-name')).isDisplayed()).toBeTruthy();
Since you're using AngularJS
to control the visibility of that element, you could also check its class attribute for ng-hide
like this:
var spinner = element.by.css('i.icon-spin');
expect(spinner.getAttribute('class')).not.toMatch('ng-hide'); // expect element to be visible
I am using rails and ajax too and I had the same problem. just run this code
$('#modalName').modal('hide');
that worked for me but I am trying to also fix it without using jQuery.
HashMaps don't keep your key/value pairs in a specific order. They are ordered based on the hash that each key's returns from its Object.hashCode() method. You can however iterate over the set of key/value pairs using an iterator with:
for (String key : hashmap.keySet())
{
for (list : hashmap.get(key))
{
//list.toString()
}
}
I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).
The only difference would be if you try to reassign it before the end of this very file.
I was facing similar problems trying to do some dat import on an intermediate schema (that later we move on to the final one). As we rely on things like extensions (for example PostGIS), the "run_insert" sql file did not fully solved the problem.
After a while, we've found that at least with Postgres 9.3 the solution is far easier... just create your SQL script always specifying the schema when refering to the table:
CREATE TABLE "my_schema"."my_table" (...);
COPY "my_schema"."my_table" (...) FROM stdin;
This way using psql -f xxxxx
works perfectly, and you don't need to change search_paths nor use intermediate files (and won't hit extension schema problems).
We can simply write:
psql --version
output show like:
psql (PostgreSQL) 11.5 (Ubuntu 11.5-1.pgdg18.04+1)
The simplest way to add a column is to use "withColumn". Since the dataframe is created using sqlContext, you have to specify the schema or by default can be available in the dataset. If the schema is specified, the workload becomes tedious when changing every time.
Below is an example that you can consider:
from pyspark.sql import SQLContext
from pyspark.sql.types import *
sqlContext = SQLContext(sc) # SparkContext will be sc by default
# Read the dataset of your choice (Already loaded with schema)
Data = sqlContext.read.csv("/path", header = True/False, schema = "infer", sep = "delimiter")
# For instance the data has 30 columns from col1, col2, ... col30. If you want to add a 31st column, you can do so by the following:
Data = Data.withColumn("col31", "Code goes here")
# Check the change
Data.printSchema()

, the table will still calculate the width automatically.

Just drop them:
nms.dropna(thresh=2)
this will drop all rows where there are at least two non-NaN
.
Then you could then drop where name is NaN
:
In [87]:
nms
Out[87]:
movie name rating
0 thg John 3
1 thg NaN 4
3 mol Graham NaN
4 lob NaN NaN
5 lob NaN NaN
[5 rows x 3 columns]
In [89]:
nms = nms.dropna(thresh=2)
In [90]:
nms[nms.name.notnull()]
Out[90]:
movie name rating
0 thg John 3
3 mol Graham NaN
[2 rows x 3 columns]
EDIT
Actually looking at what you originally want you can do just this without the dropna
call:
nms[nms.name.notnull()]
UPDATE
Looking at this question 3 years later, there is a mistake, firstly thresh
arg looks for at least n
non-NaN
values so in fact the output should be:
In [4]:
nms.dropna(thresh=2)
Out[4]:
movie name rating
0 thg John 3.0
1 thg NaN 4.0
3 mol Graham NaN
It's possible that I was either mistaken 3 years ago or that the version of pandas I was running had a bug, both scenarios are entirely possible.
You can set events on a combination of key and mouse events, and onblur as well, to be sure. In that event, store the value of the input. In the next call, compare the current value with the lastly stored value. Only do your magic if it has actually changed.
To do this in a more or less clean way:
You can associate data with a DOM element (lookup api.jquery.com/jQuery.data ) So you can write a generic set of event handlers that are assigned to all elements in the form. Each event can pass the element it was triggered by to one generic function. That one function can add the old value to the data of the element. That way, you should be able to implement this as a generic piece of code that works on your whole form and every form you'll write from now on. :) And it will probably take no more than about 20 lines of code, I guess.
An example is in this fiddle: http://jsfiddle.net/zeEwX/
override func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
let delete = UITableViewRowAction(style: .Destructive, title: "Delete") { (action, indexPath) in
// delete item at indexPath
}
let share = UITableViewRowAction(style: .Normal, title: "Disable") { (action, indexPath) in
// share item at indexPath
}
share.backgroundColor = UIColor.blueColor()
return [delete, share]
}
The above code shows how to create to custom buttons when your swipe on the row.
Put this method in your BaseController:
@SuppressWarnings("ConstantConditions")
protected String fetchClientIpAddr() {
HttpServletRequest request = ((ServletRequestAttributes) (RequestContextHolder.getRequestAttributes())).getRequest();
String ip = Optional.ofNullable(request.getHeader("X-FORWARDED-FOR")).orElse(request.getRemoteAddr());
if (ip.equals("0:0:0:0:0:0:0:1")) ip = "127.0.0.1";
Assert.isTrue(ip.chars().filter($ -> $ == '.').count() == 3, "Illegal IP: " + ip);
return ip;
}
Adding @WebAppConfiguration
(org.springframework.test.context.web.WebAppConfiguration
) annotation to your DemoApplicationTests class will work.
Insted of
drawer.setDrawerListener(toggle);
You can use
drawer.addDrawerListener(toggle);
Rails 4 now uses strong parameters.
Protecting attributes is now done in the controller. This is an example:
class PeopleController < ApplicationController
def create
Person.create(person_params)
end
private
def person_params
params.require(:person).permit(:name, :age)
end
end
No need to set attr_accessible
in the model anymore.
accepts_nested_attributes_for
In order to use accepts_nested_attribute_for
with strong parameters, you will need to specify which nested attributes should be whitelisted.
class Person
has_many :pets
accepts_nested_attributes_for :pets
end
class PeopleController < ApplicationController
def create
Person.create(person_params)
end
# ...
private
def person_params
params.require(:person).permit(:name, :age, pets_attributes: [:name, :category])
end
end
Keywords are self-explanatory, but just in case, you can find more information about strong parameters in the Rails Action Controller guide.
Note: If you still want to use attr_accessible
, you need to add protected_attributes
to your Gemfile
. Otherwise, you will be faced with a RuntimeError
.
You can see the full table of percentages to hex values and run the code in this playground in https://play.golang.org/p/l1JaPYFzDkI .
More infos for the conversion decimal <=> hexadecimal
The problem can be solved generically by a cross multiplication.
We have a percentage (ranging from 0 to 100 ) and another number (ranging from 0 to 255) then converted to hexadecimal.
For 1%
For 2%
The table in the best answer gives the percentage by step of 5%.
How to calculate the numbers between in your head ? Due to the 2.5 increment, add 2 to the first and 3 to the next
I prefer to teach how to find the solution rather than showing an answer table you don't know where the results come from.
