DateTime
inherits its equals
method from AbstractInstant
. It is implemented as such
public boolean equals(Object readableInstant) { // must be to fulfil ReadableInstant contract if (this == readableInstant) { return true; } if (readableInstant instanceof ReadableInstant == false) { return false; } ReadableInstant otherInstant = (ReadableInstant) readableInstant; return getMillis() == otherInstant.getMillis() && FieldUtils.equals(getChronology(), otherInstant.getChronology()); }
Notice the last line comparing chronology. It's possible your instances' chronologies are different.
I got this error when I made the bonehead mistake of importing MatSnackBar
instead of MatSnackBarModule
in app.module.ts
.
According to your package.json, you're using Angular 8.3, but you've imported angular/cdk v9. You can downgrade your angular/cdk version or you can upgrade your Angular version to v9 by running:
ng update @angular/core @angular/cli
That will update your local angular version to 9. Then, just to sync material, run:
ng update @angular/material
It's really simple to fix the issue, however keep in mind that you should fork and commit your changes for each library you are using in their repositories to help others as well.
Let's say you have something like this in your code:
$str = "test";
echo($str{0});
since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated, so change the above syntax into this:
$str = "test";
echo($str[0]);
Fixing the code in the question will look something like this:
public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{
$records = $this->listRecords($zoneID, $type, $name);
if (isset($records->result[0]->id)) {
return $records->result[0]->id;
}
return false;
}
None of these answers worked for me, I had to do the following:
Source: https://superuser.com/q/44503
I had the same problem, as it did not installed
@angular-devkit/build-angular
The answer which has worked for me was this:
npm i --only=dev
If you are getting the following error while connecting the mysql (either local or mysql container running the mysql):
java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed
Solution: Add the following line in your database service:
command: --default-authentication-plugin=mysql_native_password
npm i --save-dev @angular-devkit/build-angular
This code install @angular-devkit/build-angular
as dev dependency.
100% TESTED.
Here is what worked for me (Angular 7):
First import HttpClientModule in your app.module.ts if you didn't:
import { HttpClientModule } from '@angular/common/http';
...
imports: [
HttpClientModule
],
Then change your service
@Injectable()
export class FooService {
to
@Injectable({
providedIn: 'root'
})
export class FooService {
Hope it helps.
Edit:
providedIn
Determines which injectors will provide the injectable, by either associating it with an @NgModule or other InjectorType, or by specifying that this injectable should be provided in one of the following injectors:
'root' : The application-level injector in most apps.
'platform' : A special singleton platform injector shared by all applications on the page.
'any' : Provides a unique instance in every module (including lazy modules) that injects the token.
Be careful platform
is available only since Angular 9 (https://blog.angular.io/version-9-of-angular-now-available-project-ivy-has-arrived-23c97b63cfa3)
Read more about Injectable here: https://angular.io/api/core/Injectable
I had the SAME issue today and it was driving me nuts!!! What I had done was upgrade to node 8.10 and upgrade my NPM to the latest I uninstalled angular CLI
npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
I then verified my Cache from NPM if it wasn't up to date I cleaned it and ran the install again
if npm version is < 5 then use npm cache clean --force
npm install -g @angular/cli@latest
and created a new project file and create a new angular project.
the problem is in the MatInputModule:
exports: [
MatInputModule
]
Go to app.module.ts
import import { HttpClientModule } from '@angular/common/http';
AND
Add HttpClientModule
under imports
should look like this
imports: [BrowserModule, IonicModule.forRoot(), AppRoutingModule,HttpClientModule]
I had the same problem with an Angular 6+ app and ASP.NET Core 2.0
I had just previously tried to change the Angular app from CSS to SCSS.
My solution was to go to the src/angularApp
folder and running ng serve
. This helped me realize that I had missed changing the src/styles.css
file to src/styles.scss
If you are exporting another class in that module, make sure that it is not in between @Component
and your ClassComponent
. For example:
@Component({ ... })
export class ExampleClass{}
export class ComponentClass{} --> this will give this error.
FIX:
export class ExampleClass{}
@Component ({ ... })
export class ComponentClass{}
Use the INTERVAL
type to it. E.g:
--yesterday
SELECT NOW() - INTERVAL '1 DAY';
--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;
Then you can do the following on your query:
SELECT
org_id,
count(accounts) AS COUNT,
((date_at) - INTERVAL '1 DAY') AS dateat
FROM
sourcetable
WHERE
date_at <= now() - INTERVAL '130 DAYS'
GROUP BY
org_id,
dateat;
You can append multiple operands. E.g.: how to get last day of current month?
SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';
You can also create an interval using make_interval
function, useful when you need to create it at runtime (not using literals):
SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);
For each error of the form:
npm WARN {something} requires a peer of {other thing} but none is installed. You must install peer dependencies yourself.
You should:
$ npm install --save-dev "{other thing}"
Note: The quotes are needed if the {other thing}
has spaces, like in this example:
npm WARN [email protected] requires a peer of rollup@>=0.66.0 <2 but none was installed.
Resolved with:
$ npm install --save-dev "rollup@>=0.66.0 <2"
You can try this:
this.activatedRoute.paramMap.subscribe(x => {
let id = x.get('id');
console.log(id);
});
Install Django pylint:
pip install pylint-django
ctrl+shift+p > Preferences: Configure Language Specific Settings > Python
The settings.json available for python language should look like the below:
{
"python.linting.pylintArgs": [
"--load-plugins=pylint_django"
],
"[python]": {
}
}
In my case it happen because RouterModule was missed in the import.
In your HTML code
<form [formGroup]="userForm">
<input type="text" class="form-control" [value]="item.UserFirstName" formControlName="UserFirstName">
<input type="text" class="form-control" [value]="item.UserLastName" formControlName="UserLastName">
</form>
In your Typescript code
export class UserprofileComponent implements OnInit {
userForm: FormGroup;
constructor(){
this.userForm = new FormGroup({
UserFirstName: new FormControl(),
UserLastName: new FormControl()
});
}
}
This works perfectly, it does not give any error.
In my case this was required:
npm install @angular/compiler --save
npm install @angular/cli --save-dev
In my case, I added my component to declarations and entryComponents and got the same errors. I also needed to add MatDialogModule to imports.
JJB's answer got me on the right track, but the upgrade didn't go very smoothly. My process is detailed below. Hopefully the process becomes easier in the future and JJB's answer can be used or something even more straightforward.
I have followed the steps captured in JJB's answer to update the angular-cli precisely. However, after running npm install
angular-cli was broken. Even trying to do ng version
would produce an error. So I couldn't do the ng init
command. See error below:
$ ng init
core_1.Version is not a constructor
TypeError: core_1.Version is not a constructor
at Object.<anonymous> (C:\_git\my-project\code\src\main\frontend\node_modules\@angular\compiler-cli\src\version.js:18:19)
at Module._compile (module.js:556:32)
at Object.Module._extensions..js (module.js:565:10)
at Module.load (module.js:473:32)
...
To be able to use any angular-cli commands, I had to update my package.json file by hand and bump the @angular dependencies to 2.4.1, then do another npm install
.
After this I was able to do ng init
. I updated my configuration files, but none of my app/* files. When this was done, I was still getting errors. The first one is detailed below, the second was the same type of error but in a different file.
ERROR in Error encountered resolving symbol values statically. Function calls are not supported. Consider replacing the function or lambda with a reference to an exported function (position 62:9 in the original .ts file), resolving symbol AppModule in C:/_git/my-project/code/src/main/frontend/src/app/app.module.ts
This error is tied to the following factory provider in my AppModule
{ provide: Http, useFactory:
(backend: XHRBackend, options: RequestOptions, router: Router, navigationService: NavigationService, errorService: ErrorService) => {
return new HttpRerouteProvider(backend, options, router, navigationService, errorService);
}, deps: [XHRBackend, RequestOptions, Router, NavigationService, ErrorService]
}
To address this error, I had use an exported function and made the following change to the provider.
{
provide: Http,
useFactory: httpFactory,
deps: [XHRBackend, RequestOptions, Router, NavigationService, ErrorService]
}
... // elsewhere in AppModule
export function httpFactory(backend: XHRBackend,
options: RequestOptions,
router: Router,
navigationService: NavigationService,
errorService: ErrorService) {
return new HttpRerouteProvider(backend, options, router, navigationService, errorService);
}
To summarize what I understand to be the most important details, the following changes were required:
Update angular-cli version using the steps detailed in JJB's answer (and on their github page).
Updating @angular version by hand, 2.0.0 did not seem to be supported by angular-cli version 1.0.0-beta.24
With the assistance of angular-cli and the ng init
command, I updated my configuration files. I think the critical changes were to angular-cli.json and package.json. See configuration file changes at the bottom.
Make code changes to export functions before I reference them, as captured in the solution details.
angular-cli.json changes

My package.json looks like this after a manual merge that considers the versions used by ng-init. Note my angular version is not 2.4.1, but the change I was after was component inheritance which was introduced in 2.3, so I was fine with these versions. The original package.json is in the question.

I followed each of the suggestions here (I'm using Angular 7), but nothing worked. My app refused to acknowledge that @angular/material existed, so it showed an error on this line:
import { MatCheckboxModule } from '@angular/material';
Even though I was using the --save
parameter to add Angular Material to my project:
npm install --save @angular/material @angular/cdk
...it refused to add anything to my "package.json
" file.
I even tried deleting the package-lock.json
file, as some articles suggest that this causes problems, but this had no effect.
To fix this issue, I had to manually add these two lines to my "package.json
" file.
{
"devDependencies": {
...
"@angular/material": "~7.2.2",
"@angular/cdk": "~7.2.2",
...
What I can't tell is whether this is an issue related to using Angular 7, or if it's been around for years....
When using moment.js, use:
var tz = moment.tz.guess();
It will return an IANA time zone identifier, such as America/Los_Angeles
for the US Pacific time zone.
It is documented here.
Internally, it first tries to get the time zone from the browser using the following call:
Intl.DateTimeFormat().resolvedOptions().timeZone
If you are targeting only modern browsers that support this function, and you don't need Moment-Timezone for anything else, then you can just call that directly.
If Moment-Timezone doesn't get a valid result from that function, or if that function doesn't exist, then it will "guess" the time zone by testing several different dates and times against the Date
object to see how it behaves. The guess is usually a good enough approximation, but not guaranteed to exactly match the time zone setting of the computer.
Watch out if you are going to compare dates after the conversion!
For instance, I got simulator's asset with date as TimeInterval(366144731.9), converted to milliseconds Int64(1344451931900) and back to TimeInterval(366144731.9000001), using
func convertToMilli(timeIntervalSince1970: TimeInterval) -> Int64 {
return Int64(timeIntervalSince1970 * 1000)
}
func convertMilliToDate(milliseconds: Int64) -> Date {
return Date(timeIntervalSince1970: (TimeInterval(milliseconds) / 1000))
}
I tried to fetch the asset by creationDate and it doesn't find the asset, as you could figure, the numbers are not the same.
I tried multiple solutions to reduce double's decimal precision, like round(interval*1000)/1000, use NSDecimalNumber, etc... with no success.
I ended up fetching by interval -1 < creationDate < interval + 1, instead of creationDate == Interval.
There may be a better solution!?
The problem is in your main.ts
file.
const platform = platformBrowserDynamic();
platform.bootstrapModule(App);
You are trying to bootstrap App
, which is not a real module.
Delete these two lines and replace with the following line:
platformBrowserDynamic().bootstrapModule(AppModule);
and it will fix your error.
check whether you import FormsModule. There's no ngControl in the new forms angular 2 release version. you have to change your template to as an example
<div class="row">
<div class="form-group col-sm-7 col-md-5">
<label for="name">Name</label>
<input type="text" class="form-control" required
[(ngModel)]="user.name"
name="name" #name="ngModel">
<div [hidden]="name.valid || name.pristine" class="alert alert-danger">
Name is required
</div>
</div>
</div>
The answer comes from the javadoc of ZoneId
(emphasis mine) ...
A ZoneId is used to identify the rules used to convert between an Instant and a LocalDateTime. There are two distinct types of ID:
- Fixed offsets - a fully resolved offset from UTC/Greenwich, that uses the same offset for all local date-times
- Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply
Most fixed offsets are represented by ZoneOffset. Calling normalized() on any ZoneId will ensure that a fixed offset ID will be represented as a ZoneOffset.
... and from the javadoc of ZoneId#of
(emphasis mine):
This method parses the ID producing a ZoneId or ZoneOffset. A ZoneOffset is returned if the ID is 'Z', or starts with '+' or '-'.
The argument id is specified as "UTC"
, therefore it will return a ZoneId
with an offset, which also presented in the string form:
System.out.println(now.withZoneSameInstant(ZoneOffset.UTC));
System.out.println(now.withZoneSameInstant(ZoneId.of("UTC")));
Outputs:
2017-03-10T08:06:28.045Z
2017-03-10T08:06:28.045Z[UTC]
As you use the equals
method for comparison, you check for object equivalence. Because of the described difference, the result of the evaluation is false
.
When the normalized()
method is used as proposed in the documentation, the comparison using equals
will return true
, as normalized()
will return the corresponding ZoneOffset
:
Normalizes the time-zone ID, returning a ZoneOffset where possible.
now.withZoneSameInstant(ZoneOffset.UTC)
.equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())); // true
As the documentation states, if you use "Z"
or "+0"
as input id, of
will return the ZoneOffset
directly and there is no need to call normalized()
:
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("Z"))); //true
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("+0"))); //true
To check if they store the same date time, you can use the isEqual
method instead:
now.withZoneSameInstant(ZoneOffset.UTC)
.isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))); // true
Sample
System.out.println("equals - ZoneId.of(\"UTC\"): " + nowZoneOffset
.equals(now.withZoneSameInstant(ZoneId.of("UTC"))));
System.out.println("equals - ZoneId.of(\"UTC\").normalized(): " + nowZoneOffset
.equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())));
System.out.println("equals - ZoneId.of(\"Z\"): " + nowZoneOffset
.equals(now.withZoneSameInstant(ZoneId.of("Z"))));
System.out.println("equals - ZoneId.of(\"+0\"): " + nowZoneOffset
.equals(now.withZoneSameInstant(ZoneId.of("+0"))));
System.out.println("isEqual - ZoneId.of(\"UTC\"): "+ nowZoneOffset
.isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))));
Output:
equals - ZoneId.of("UTC"): false
equals - ZoneId.of("UTC").normalized(): true
equals - ZoneId.of("Z"): true
equals - ZoneId.of("+0"): true
isEqual - ZoneId.of("UTC"): true
This is an other way to solve your problem. So please check out below solution. Hope it will help you.
let str = "{\"names\": [\"Bob\", \"Tim\", \"Tina\"]}"
let data = str.data(using: String.Encoding.utf8, allowLossyConversion: false)!
do {
let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String: AnyObject]
if let names = json["names"] as? [String] {
print(names)
}
} catch let error as NSError {

}
You should declare it with declarations array(meta property) of @NgModule
as shown below (RC5 and later
),
import {CoursesComponent} from './courses.component';
@NgModule({
imports: [ BrowserModule],
declarations: [ AppComponent,CoursesComponent], //<----here
providers: [],
bootstrap: [ AppComponent ]
})
Here is a part of my code that parse JSON, it may be helpful for you:
import { Component, Input } from '@angular/core';
import { Injectable } from '@angular/core';
import { Http, Response, Headers, RequestOptions } from '@angular/http';
import {Observable} from 'rxjs/Rx';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
@Injectable()
export class AppServices{
constructor(private http: Http) {
var obj;
this.getJSON().subscribe(data => obj=data, error => console.log(error));
}
public getJSON(): Observable<any> {
return this.http.get("./file.json")
.map((res:any) => res.json())
.catch((error:any) => console.log(error));
}
}
Another reason could be some code like this:
import { NgModule } from '@angular/core';_x000D_
import { SharedModule } from 'app/shared/shared.module';_x000D_
import { CoreModule } from 'app/core/core.module';_x000D_
import { RouterModule } from '@angular/router';_x000D_
import { COMPANY_ROUTES } from 'app/company/company.routing';_x000D_
import { CompanyService } from 'app/company/services/company.service';_x000D_
import { CompanyListComponent } from 'app/company/components/company-list/company-list.component';_x000D_
_x000D_
@NgModule({_x000D_
imports: [_x000D_
CoreModule,_x000D_
SharedModule,_x000D_
RouterModule.forChild(COMPANY_ROUTES)_x000D_
],_x000D_
declarations: [_x000D_
CompanyListComponent_x000D_
],_x000D_
providers: [_x000D_
CompanyService_x000D_
],_x000D_
exports: [_x000D_
]_x000D_
})_x000D_
export class CompanyModule { }
_x000D_
Because exports is empty array and it has , before it, it should be removed.
I have created a module for pipes in the same directory where my pipes are present
import { NgModule } from '@angular/core';
///import pipe...
import { Base64ToImage, TruncateString} from './'
@NgModule({
imports: [],
declarations: [Base64ToImage, TruncateString],
exports: [Base64ToImage, TruncateString]
})
export class SharedPipeModule { }
Now import that module in app.module:
import {SharedPipeModule} from './pipe/shared.pipe.module'
@NgModule({
imports: [
...
, PipeModule.forRoot()
....
],
Now it can be used by importing the same in the nested module
Just call moment as a function without any arguments:
moment()
For timezone information with moment, look at the moment-timezone
package: http://momentjs.com/timezone/
For using [(ngModel)]
in Angular 2, 4 & 5+, you need to import FormsModule from Angular form...
Also, it is in this path under forms in the Angular repository on GitHub:
angular / packages / forms / src / directives / ng_model.ts
Probably this is not a very pleasurable for the AngularJS developers as you could use ng-model everywhere anytime before, but as Angular tries to separate modules to use whatever you'd like you to want to use at the time, ngModel is in FormsModule now.
Also, if you are using ReactiveFormsModule it needs to import it too.
So simply look for app.module.ts and make sure you have FormsModule
imported in...
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms'; // <<<< import it here
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule, FormsModule // <<<< And here
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Also, these are the current starting comments for Angular4 ngModel
in FormsModule:
/**
* `ngModel` forces an additional change detection run when its inputs change:
* E.g.:
* ```
* <div>{{myModel.valid}}</div>
* <input [(ngModel)]="myValue" #myModel="ngModel">
* ```
* I.e. `ngModel` can export itself on the element and then be used in the template.
* Normally, this would result in expressions before the `input` that use the exported directive
* to have and old value as they have been
* dirty checked before. As this is a very common case for `ngModel`, we added this second change
* detection run.
*
* Notes:
* - this is just one extra run no matter how many `ngModel` have been changed.
* - this is a general problem when using `exportAs` for directives!
*/
If you'd like to use your input, not in a form, you can use it with ngModelOptions
and make standalone true...
[ngModelOptions]="{standalone: true}"
For more information, look at ng_model in the Angular section here.
There is an open issue to only print this warning if there was actually something sanitized: https://github.com/angular/angular/pull/10272
I didn't read in detail when this warning is printed when nothing was sanitized.
The problem seems to be with Instant Run feature.Go to "File -> Settings -> Build, Execution, Deployment -> Instant Run" and just disable it.
Hope this works if above answers doesnt work..
If your input always has a time zone of "zulu" ("Z" = UTC), then you can use DateTimeFormatter.ISO_INSTANT
(implicitly):
final Instant parsed = Instant.parse(dateTime);
If time zone varies and has the form of "+01:00" or "+01:00:00" (when not "Z"), then you can use DateTimeFormatter.ISO_OFFSET_DATE_TIME
:
DateTimeFormatter formatter = DateTimeFormatter.ISO_OFFSET_DATE_TIME;
final ZonedDateTime parsed = ZonedDateTime.parse(dateTime, formatter);
If neither is the case, you can construct a DateTimeFormatter
in the same manner as DateTimeFormatter.ISO_OFFSET_DATE_TIME
is constructed.
Your current pattern has several problems:
ResolverStyle.STRICT
);yyyy
instead of uuuu
(yyyy
will not work in strict mode);hh
instead of 24-hour HH
;S
for fractional seconds, but input has three.You have to declare 2 different NSDateFormatters
, the first to convert the string to a NSDate
and the second to print the date in your format.
Try this code:
let dateFormatterGet = NSDateFormatter()
dateFormatterGet.dateFormat = "yyyy-MM-dd HH:mm:ss"
let dateFormatterPrint = NSDateFormatter()
dateFormatterPrint.dateFormat = "MMM dd,yyyy"
let date: NSDate? = dateFormatterGet.dateFromString("2016-02-29 12:24:26")
print(dateFormatterPrint.stringFromDate(date!))
Swift 3 and higher:
From Swift 3 NSDate
class has been changed to Date
and NSDateFormatter
to DateFormatter
.
let dateFormatterGet = DateFormatter()
dateFormatterGet.dateFormat = "yyyy-MM-dd HH:mm:ss"
let dateFormatterPrint = DateFormatter()
dateFormatterPrint.dateFormat = "MMM dd,yyyy"
if let date = dateFormatterGet.date(from: "2016-02-29 12:24:26") {
print(dateFormatterPrint.string(from: date))
} else {
print("There was an error decoding the string")
}
I solved it by rewriting package.json
with the exact values warnings were about.
Warnings when running npm
:
npm WARN [email protected] requires a peer of es6-shim@^0.33.3 but none was installed.
npm WARN [email protected] requires a peer of [email protected]
In package.json

Finally, run the command below:
npm install
Timezones and stuff aside, a very simple alternative to new Date(startDateLong)
could be LocalDate.ofEpochDay(startDateLong / 86400000L)
A final
variable means that it can be instantiated only one time.
in Java you can't use non-final variables in lambda as well as in anonymous inner classes.
You can refactor your code with the old for-each loop:
private TimeZone extractCalendarTimeZoneComponent(Calendar cal,TimeZone calTz) {
try {
for(Component component : cal.getComponents().getComponents("VTIMEZONE")) {
VTimeZone v = (VTimeZone) component;
v.getTimeZoneId();
if(calTz==null) {
calTz = TimeZone.getTimeZone(v.getTimeZoneId().getValue());
}
}
} catch (Exception e) {
log.warn("Unable to determine ical timezone", e);
}
return null;
}
Even if I don't get the sense of some pieces of this code:
v.getTimeZoneId();
without using its return valuecalTz = TimeZone.getTimeZone(v.getTimeZoneId().getValue());
you don't modify the originally passed calTz
and you don't use it in this methodnull
, why don't you set void
as return type?Hope also these tips helps you to improve.

It's most likely that your NPM version is old, i recently had this on a developer machine at work, type:
npm -v
If it's anything less than the current stable version, and you can just update your Node.js install from here https://nodejs.org/en/ :)
If npm install -g typings typings install
still does not help, delete node_modules and typings folders before executing this command.
Converting LocalDateTime to java.util.Date
LocalDateTime localDateTime = LocalDateTime.now();
ZonedDateTime zonedDateTime = localDateTime.atZone(ZoneOffset.systemDefault());
Instant instant = zonedDateTime.toInstant();
Date date = Date.from(instant);
System.out.println("Result Date is : "+date);
In Lumen's .env file, specify the timezones. For India, it would be like:
APP_TIMEZONE = 'Asia/Calcutta'
DB_TIMEZONE = '+05:30'
Here is what I do using Intl api:
let currentTimeZone = new Intl.DateTimeFormat().resolvedOptions().timeZone; // For example: Australia/Sydney
this will return a time zone name. Pass this parameter to the following function to get the time
let dateTime = new Date(date).toLocaleDateString('en-US',{ timeZone: currentTimeZone, hour12: true});
let time = new Date(date).toLocaleTimeString('en-US',{ timeZone: currentTimeZone, hour12: true});
you can also format the time with moment like this:
moment(new Date(`${dateTime} ${time}`)).format('YYYY-MM-DD[T]HH:mm:ss');
Here's one way. You have to get the individual components from the date object (day, month & year) and then build and format the string however you wish.
n = new Date();_x000D_
y = n.getFullYear();_x000D_
m = n.getMonth() + 1;_x000D_
d = n.getDate();_x000D_
document.getElementById("date").innerHTML = m + "/" + d + "/" + y;
_x000D_
<p id="date"></p>
_x000D_
One main difference is the Local
part of LocalDateTime
. If you live in Germany and create a LocalDateTime
instance and someone else lives in USA and creates another instance at the very same moment (provided the clocks are properly set) - the value of those objects would actually be different. This does not apply to Instant
, which is calculated independently from time zone.
LocalDateTime
stores date and time without timezone, but it's initial value is timezone dependent. Instant
's is not.
Moreover, LocalDateTime
provides methods for manipulating date components like days, hours, months. An Instant
does not.
apart from the nanosecond precision advantage of Instant and the time-zone part of LocalDateTime
Both classes have the same precision. LocalDateTime
does not store timezone. Read javadocs thoroughly, because you may make a big mistake with such invalid assumptions: Instant and LocalDateTime.
If you are interested in now only, then simply use:
Date d = new Date();
In the application/config folder, get the file config.php and check for the below:
$config['time_reference'] = '';
Change the value to your preferred time zone. For example to set time zone to Nairobi Kenya: $config['time_reference'] = 'Africa/Nairobi';
I want to add to the answers posted on above that none of the solutions proposed here worked for me. My WAMP, is working on port 3308 instead of 3306 which is what it is installed by default. I found out that when working in a local environment, if you are using mysqladmin in your computer (for testing environment), and if you are working with port other than 3306, you must define your variable DB_SERVER with the value localhost:NumberOfThePort, so it will look like the following: define("DB_SERVER", "localhost:3308"). You can obtain this value by right-clicking on the WAMP icon in your taskbar (on the hidden icons section) and select Tools. You will see the section: "Port used by MySQL: NumberOfThePort"
This will fix your connection to your database.
This was the error I got: Error: SQLSTATE[HY1045] Access denied for user 'username'@'localhost' on line X.
I hope this helps you out.

I found this question looking to change the timezone in my Django project's settings.py
file to the United Kingdom.
Using the tz database in jfs' solution I found the answer:
TIME_ZONE = 'Europe/London'
The T
doesn't really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time.
The Z
stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC).
Both characters are just static letters in the format, which is why they are not documented by the datetime.strftime()
method. You could have used Q
or M
or Monty Python
and the method would have returned them unchanged as well; the method only looks for patterns starting with %
to replace those with information from the datetime
object.
Use utcOffset function.
var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).utcOffset(10 * 60); //set timezone offset in minutes
console.log(localDate.format()); //2015-01-30T20:00:00+10:00
I posted too soon however the ways to configure are given in below link
http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html
and way to get access keys are given in below link

I faced this exception for a long time and was not able to pinpoint the problem. The exception says line 1 column 9. The mistake I did is to get the first line of the file which flume is processing.
Apache flume process the content of the file in patches. So, when flume throws this exception and says line 1, it means the first line in the current patch.
If your flume agent is configured to use batch size = 100, and (for example) the file contains 400 lines, this means the exception is thrown in one of the following lines 1, 101, 201,301.
How to discover the line which causes the problem?
You have three ways to do that.
1- pull the source code and run the agent in debug mode. If you are an average developer like me and do not know how to make this, check the other two options.
2- Try to split the file based on the batch size and run the flume agent again. If you split the file into 4 files, and the invalid json exists between lines 301 and 400, the flume agent will process the first 3 files and stop at the fourth file. Take the fourth file and again split it into more smaller files. continue the process until you reach a file with only one line and flume fails while processing it.
3- Reduce the batch size of the flume agent to only one and compare the number of processed events in the output of the sink you are using. For example, in my case I am using Solr sink. The file contains 400 lines. The flume agent is configured with batch size=100. When I run the flume agent, it fails at some point and throw that exception. At this point check how many documents are ingested in Solr. If the invalid json exists at line 346, the number of documents indexed into Solr will be 345, so the next line is the line which causes the problem.
In my case I followed the third option and fortunately I pinpoint the line which causes the problem.
This is a long answer but it actually does not solve the exception. How I overcome this exception?
I have no idea why Jackson library complain while parsing a json string contains escaped characters \n \r \t
. I think (but I am not sure) the Jackson parser is by default escaping these characters which cases the json string to be split into two lines (in case of \n
) and then it deals each line as a separate json string.
In my case we used a customized interceptor to remove these characters before being processed by the flume agent. This is the way we solved this problem.
This may or may not help you address your problem, OP, but to get the timezone of the current server relative to UTC (UT1, technically), do:
SELECT EXTRACT(TIMEZONE FROM now())/3600.0;
The above works by extracting the UT1-relative offset in minutes, and then converting it to hours using the factor of 3600 secs/hour.
Example:
SET SESSION timezone TO 'Asia/Kabul';
SELECT EXTRACT(TIMEZONE FROM now())/3600.0;
-- output: 4.5 (as of the writing of this post)
(docs).
If you're targeting iOS 11.0+ / macOS 10.13+, you simply use ISO8601DateFormatter
with the withInternetDateTime
and withFractionalSeconds
options, like so:
let date = Date()
let iso8601DateFormatter = ISO8601DateFormatter()
iso8601DateFormatter.formatOptions = [.withInternetDateTime, .withFractionalSeconds]
let string = iso8601DateFormatter.string(from: date)
// string looks like "2020-03-04T21:39:02.112Z"
I had a similar problem (join
worked, but concat
failed).
Check for duplicate index values in df1
and s1
, (e.g. df1.index.is_unique
)
Removing duplicate index values (e.g., df.drop_duplicates(inplace=True)
) or one of the methods here https://stackoverflow.com/a/34297689/7163376 should resolve it.
var mydate = "2017-06-28T00:00:00";
var weekDayName = moment(mydate).format('ddd');
console.log(weekDayName);
Result: Wed
var mydate = "2017-06-28T00:00:00";
var weekDayName = moment(mydate).format('dddd');
console.log(weekDayName);
Result: Wednesday
TL;DR; If you're still having trouble after restarting apache or nginx, also try restarting the php-fpm
service.
The answers here don't always satisfy the requirement to force a reload of the php.ini file. On numerous occasions I've taken these steps to be rewarded with no update, only to find the solution I need after also restarting the php-fpm service. So if restarting apache or nginx doesn't trigger a php.ini update although you know the files are updated, try restarting php-fpm as well.
To restart the service:
Note: prepend sudo if not root
Using SysV Init scripts directly:
/etc/init.d/php-fpm restart # typical
/etc/init.d/php5-fpm restart # debian-style
/etc/init.d/php7.0-fpm restart # debian-style PHP 7
Using service wrapper script
service php-fpm restart # typical
service php5-fpm restart # debian-style
service php7.0-fpm restart. # debian-style PHP 7
Using Upstart (e.g. ubuntu):
restart php7.0-fpm # typical (ubuntu is debian-based) PHP 7
restart php5-fpm # typical (ubuntu is debian-based)
restart php-fpm # uncommon
Using systemd (newer servers):
systemctl restart php-fpm.service # typical
systemctl restart php5-fpm.service # uncommon
systemctl restart php7.0-fpm.service # uncommon PHP 7
Or whatever the equivalent is on your system.
The above commands taken directly from this server fault answer
In my experience the bind_param
was fine but I had mistaken the database name so, I changed only the database name in the connection parameter and it worked perfectly.
I had defined root path to indicate the root folder, include path to include folder and base url for the home url of website. This will be used for calling them anywhere they are required.
You can use below code for getting current time zone
func getCurrentTimeZone() -> String{
return TimeZone.current.identifier
}
let currentTimeZone = getCurrentTimeZone()
print(currentTimeZone)
To get the date to show as the current time zone I used the following.
if let timeResult = (jsonResult["dt"] as? Double) {
let date = NSDate(timeIntervalSince1970: timeResult)
let dateFormatter = NSDateFormatter()
dateFormatter.timeStyle = NSDateFormatterStyle.MediumStyle //Set time style
dateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle //Set date style
dateFormatter.timeZone = NSTimeZone()
let localDate = dateFormatter.stringFromDate(date)
}
Swift 3.0 Version
if let timeResult = (jsonResult["dt"] as? Double) {
let date = Date(timeIntervalSince1970: timeResult)
let dateFormatter = DateFormatter()
dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style
dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style
dateFormatter.timeZone = self.timeZone
let localDate = dateFormatter.string(from: date)
}
Swift 5
if let timeResult = (jsonResult["dt"] as? Double) {
let date = Date(timeIntervalSince1970: timeResult)
let dateFormatter = DateFormatter()
dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style
dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style
dateFormatter.timeZone = .current
let localDate = dateFormatter.string(from: date)
}
I faced the same error and in my case, I change the Server Port Number to 3308 where previously it was 3306. This connect my project to the MySQL database.
Here we have to change the connection code also.
Class.forName("com.mysql.cj.jdbc.Driver");
cn=(java.sql.Connection)DriverManager.getConnection("jdbc:mysql://localhost:3308/test2?zeroDateTimeBehavior=convertToNull","root","");
Changing the port number in the connection code is also necessary as localhost:3308
to resolved the error.
To get the current time in the local timezone as a naive datetime object:
from datetime import datetime
naive_dt = datetime.now()
If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).
To get the current time in UTC as a naive datetime object:
naive_utc_dt = datetime.utcnow()
To get the current time as an aware datetime object in Python 3.3+:
from datetime import datetime, timezone
utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time
To get the current time in the given time zone from the tz database:
import pytz
tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)
It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.
It looks like there was an issue with my migration.
I ran ./manage.py schemamigration research --auto
and found that many of the fields didn't have a default specified.
So, I ran ./manage.py schemamigration research --init
followed by ./manage.py migrate research
Rerunning the server from there did the trick!
Duration duration = Duration.between(start, end);
duration = duration.minusDays(duration.toDaysPart()); // essentially "duration (mod 1 day)"
Period period = Period.between(start.toLocalDate(), end.toLocalDate());
and then use the methods period.getYears()
, period.getMonths()
, period.getDays()
, duration.toHoursPart()
, duration.toMinutesPart()
, duration.toSecondsPart()
.
I'll answer the original question, i.e. how to get the time difference between two LocalDateTimes
in years, months, days, hours & minutes, such that the "sum" (see note below) of all the values for the different units equals the total temporal difference, and such that the value in each unit is smaller than the next bigger unit—i.e. minutes < 60
, hours < 24
, and so on.
Given two LocalDateTimes
start
and end
, e.g.
LocalDateTime start = LocalDateTime.of(2019, 11, 29, 17, 15);
LocalDateTime end = LocalDateTime.of(2020, 11, 30, 18, 44);
we can represent the absolute timespan between the two with a Duration
—perhaps using Duration.between(start, end)
. But the biggest unit we can extract out of a Duration
is days (as a temporal unit equivalent to 24h)—see the note below for an explanation. To use larger units (months, years) we can represent this Duration
with a pair of (Period
, Duration
), where the Period
measures the difference up to a precision of days and the Duration
represents the remainder:
Duration duration = Duration.between(start, end);
duration = duration.minusDays(duration.toDaysPart()); // essentially "duration (mod 1 day)"
Period period = Period.between(start.toLocalDate(), end.toLocalDate());
Now we can simply use the methods defined on Period
and Duration
to extract the individual units:
System.out.printf("%d years, %d months, %d days, %d hours, %d minutes, %d seconds",
period.getYears(), period.getMonths(), period.getDays(), duration.toHoursPart(),
duration.toMinutesPart(), duration.toSecondsPart());
1 years, 0 months, 1 days, 1 hours, 29 minutes, 0 seconds
or, using the default format:
System.out.println(period + " + " + duration);
P1Y1D + PT1H29M
Note that, in java.time
's conception, "units" like "month" or "year" don't represent a fixed, absolute temporal value—they're date- and calendar-dependent, as the following example illustrates:
LocalDateTime
start1 = LocalDateTime.of(2020, 1, 1, 0, 0),
end1 = LocalDateTime.of(2021, 1, 1, 0, 0),
start2 = LocalDateTime.of(2021, 1, 1, 0, 0),
end2 = LocalDateTime.of(2022, 1, 1, 0, 0);
System.out.println(Period.between(start1.toLocalDate(), end1.toLocalDate()));
System.out.println(Duration.between(start1, end1).toDays());
System.out.println(Period.between(start2.toLocalDate(), end2.toLocalDate()));
System.out.println(Duration.between(start2, end2).toDays());

LocalDateTime
is a date-time without a time-zone. You specified the time zone offset format symbol in the format, however, LocalDateTime
doesn't have such information. That's why the error occured.
If you want time-zone information, you should use ZonedDateTime
.
DateTimeFormatter FORMATTER = DateTimeFormatter.ofPattern("yyyyMMdd HH:mm:ss.SSSSSS Z");
ZonedDateTime.now().format(FORMATTER);
=> "20140829 14:12:22.122000 +09"
Swift 3 : Xcode 8 helper function:
func getDayOfWeek(fromDate date: Date) -> String? {
let cal = Calendar(identifier: .gregorian)
let dayOfWeek = cal.component(.weekday, from: date)
switch dayOfWeek {
case 1:
return "Sunday"
case 2:
return "Monday"
case 3:
return "Tuesday"
case 4:
return "Wednesday"
case 5:
return "Thursday"
case 6:
return "Friday"
case 7:
return "Saturday"
default:
return nil
}
}
You could try using FontAwesome. It contains a sort-icon (http://fontawesome.io/icon/sort/).
To do so, you would
need to include fontawesome:
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">
and then simply use the fontawesome-icon instead of the default-bootstrap-icons in your th
's:
<th><b>#</b> <i class="fa fa-fw fa-sort"></i></th>
Hope that helps.
Use this command to find your active zone(s):
firewall-cmd --get-active-zones
It will say either public, dmz, or something else. You should only apply to the zones required.
In the case of public try:
firewall-cmd --zone=public --add-port=2888/tcp --permanent
Then remember to reload the firewall for changes to take effect.
firewall-cmd --reload
Otherwise, substitute public for your zone, for example, if your zone is dmz:
firewall-cmd --zone=dmz --add-port=2888/tcp --permanent
Similar to colMeans
, colSums
, etc, you could write a column maximum function, colMax
, and a column sort function, colSort
.
colMax <- function(data) sapply(data, max, na.rm = TRUE)
colSort <- function(data, ...) sapply(data, sort, ...)
I use ...
in the second function in hopes of sparking your intrigue.
Get your data:
dat <- read.table(h=T, text = "Ozone Solar.R Wind Temp Month Day

3 12 149 12.6 74 5 3
4 18 313 11.5 62 5 4
5 NA NA 14.3 56 5 5
6 28 NA 14.9 66 5 6

8 19 99 13.8 59 5 8
9 8 19 20.1 61 5 9")
Use colMax
function on sample data:
colMax(dat)
# Ozone Solar.R Wind Temp Month Day
# 41.0 313.0 20.1 74.0 5.0 9.0
To do the sorting on a single column,
sort(dat$Solar.R, decreasing = TRUE)
# [1] 313 299 190 149 118 99 19
and over all columns use our colSort
function,
colSort(dat, decreasing = TRUE) ## compare with '...' above

I just used getLocaleString() function for my application. It should adapt the timeformat common to the locale, so no +0200 etc. Ofcourse, there will be less possibility for controlling the width of your string then.
var str = (new Date(1400167800)).toLocaleString();
You want to convert it to an object first and then access normally making sure to cast it.

java.util.Date
is independent of the timezone. When you print cal_Two
though the Calendar
instance has got its timezone set to UTC
, cal_Two.getTime()
would return a Date
instance which does not have a timezone (and is always in the default timezone)
Calendar cal_Two = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
System.out.println(cal_Two.getTime());
System.out.println(cal_Two.getTimeZone());
Output:
Sat Jan 25 16:40:28 IST 2014
sun.util.calendar.ZoneInfo[id="UTC",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
From the javadoc of TimeZone.setDefault()
Sets the TimeZone that is returned by the getDefault method. If zone is null, reset the default to the value it had originally when the VM first started.
Hence, moving your setDefault()
before cal_Two
is instantiated you would get the correct result.
TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
Calendar cal_Two = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
System.out.println(cal_Two.getTime());
Calendar cal_Three = Calendar.getInstance();
System.out.println(cal_Three.getTime());
Output:
Sat Jan 25 11:15:29 UTC 2014
Sat Jan 25 11:15:29 UTC 2014
if you want to align only this cells, you can do something like this:
$style = array(
'alignment' => array(
'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
)
);
$sheet->getStyle("A1:B1")->applyFromArray($style);
But, if you want to apply this style to all cells, try this:
$style = array(
'alignment' => array(
'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
)
);
$sheet->getDefaultStyle()->applyFromArray($style);
One-liner for your problem:
data = [json.loads(line) for line in open('tweets.json', 'r')]
You state in the comments that the returned JSON is this:
{
"dstOffset" : 3600,
"rawOffset" : 36000,
"status" : "OK",
"timeZoneId" : "Australia/Hobart",
"timeZoneName" : "Australian Eastern Daylight Time"
}
You're telling Gson that you have an array of Post
objects:
List<Post> postsList = Arrays.asList(gson.fromJson(reader,
Post[].class));
You don't. The JSON represents exactly one Post
object, and Gson is telling you that.
Change your code to be:
Post post = gson.fromJson(reader, Post.class);
add this code to Your AppKernel Class:
public function init()
{
date_default_timezone_set('Asia/Tehran');
parent::init();
}
Well it was very simple. I was missing the format of the date in the json file, so I should write :
st = datetime.strptime(st, '%A %d %B %H %M')
because in the json file the date was like :
"start": "Friday 06 December 02:05",
this works perfectly in 2019:
date('Y-m-d H:i:s',strtotime($date. ' '.$timezone));
Below steps are worked for me, Hope this will work for you as well,
then write below code in a java file and run
System.setProperty("webdriver.ie.driver","path of your IE driver exe\IEDriverServer.exe");
InternetExplorerDriver driver=new InternetExplorerDriver();
driver.manage().window().maximize();
Thread.Sleep(10100);
driver.get("http://www.Google.com");
Thread.Sleep(10000);
There's a lot more to abstract classes than default method implementations (such as private state), but as of Java 8, whenever you have the choice of either, you should go with the defender (aka. default
) method in the interface.
The constraint on the default method is that it can be implemented only in the terms of calls to other interface methods, with no reference to a particular implementation's state. So the main use case is higher-level and convenience methods.
The good thing about this new feature is that, where before you were forced to use an abstract class for the convenience methods, thus constraining the implementor to single inheritance, now you can have a really clean design with just the interface and a minimum of implementation effort forced on the programmer.
The original motivation to introduce default
methods to Java 8 was the desire to extend the Collections Framework interfaces with lambda-oriented methods without breaking any existing implementations. Although this is more relevant to the authors of public libraries, you may find the same feature useful in your project as well. You've got one centralized place where to add new convenience and you don't have to rely on how the rest of the type hierarchy looks.
I once also faced such an issue where i needed to save data which was used by different collaborators and i ended up storing the time in unix timestamp form which represents the number of seconds since january 1970 which is an integer format.
Example todays date and time in tanzania is Friday, September 13, 2019 9:44:01 PM
which when store in unix timestamp would be 1568400241
Now when reading the data simply use something like php or any other language and extract the date from the unix timestamp. An example with php will be
echo date('m/d/Y', 1568400241);
This makes it easier even to store data with other collaborators in different locations. They can simply convert the date to unix timestamp with their own gmt offset and store it in a integer format and when outputting this simply convert with a
If you want to copy from searchContent to content, then code should be as follows
BeanUtils.copyProperties(content, searchContent);
You need to reverse the parameters as above in your code.
From API,
public static void copyProperties(Object dest, Object orig)
throws IllegalAccessException,
InvocationTargetException)
Parameters:
dest - Destination bean whose properties are modified
orig - Origin bean whose properties are retrieved
To get list of keys in Bash, follow the these steps.
First, define the following wrapper function to make it simple to use (copy and paste into shell):
function memcmd() {
exec {memcache}<>/dev/tcp/localhost/11211
printf "%s\n%s\n" "$*" quit >&${memcache}
cat <&${memcache}
}
You can use lru_crawler metadump all
command to dump (most of) the metadata for (all of) the items in the cache.
As opposed to
cachedump
, it does not cause severe performance problems and has no limits on the amount of keys that can be dumped.
Example command by using the previously defined function:
memcmd lru_crawler metadump all
See: ReleaseNotes1431.
Get list of slabs by using items statistics command, e.g.:
memcmd stats items
For each slub class, you can get list of items by specifying slub id along with limit number (0
- unlimited):
memcmd stats cachedump 1 0
memcmd stats cachedump 2 0
memcmd stats cachedump 3 0
memcmd stats cachedump 4 0
...
Note: You need to do this for each memcached server.
To list all the keys from all stubs, here is the one-liner (per one server):
for id in $(memcmd stats items | grep -o ":[0-9]\+:" | tr -d : | sort -nu); do
memcmd stats cachedump $id 0
done
Note: The above command could cause severe performance problems while accessing the items, so it's not advised to run on live.
Notes:
stats cachedump
only dumps theHOT_LRU
(IIRC?), which is managed by a background thread as activity happens. This means under a new enough version which the 2Q algo enabled, you'll get snapshot views of what's in just one of the LRU's.If you want to view everything,
lru_crawler metadump 1
(orlru_crawler metadump all
) is the new mostly-officially-supported method that will asynchronously dump as many keys as you want. you'll get them out of order but it hits all LRU's, and unless you're deleting/replacing items multiple runs should yield the same results.

docs file.@Nicolai is correct about casting and why the condition is false for any data. i guess you prefer the first form because you want to avoid date manipulation on the input string, correct? you don't need to be afraid:
SELECT *
FROM table
WHERE update_date >= '2013-05-03'::date
AND update_date < ('2013-05-03'::date + '1 day'::interval);
I think below approach will solve the conversion without taking time-zone into consideration. Please comment if it has any pitfalls.

the $scope.range in the fiddle example should be:
$scope.range = function (size,start, end) {
var ret = [];
console.log(size,start, end);
if (size < end) {
end = size;
if(size<$scope.gap){
start = 0;
}else{
start = size-$scope.gap;
}
}
for (var i = start; i < end; i++) {

I also recommend using Joda as mentioned before.
Solving your problem using standard Java Date
objects only can be done as follows:
// **** YOUR CODE **** BEGIN ****
long ts = System.currentTimeMillis();
Date localTime = new Date(ts);
String format = "yyyy/MM/dd HH:mm:ss";
SimpleDateFormat sdf = new SimpleDateFormat(format);
// Convert Local Time to UTC (Works Fine)
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
Date gmtTime = new Date(sdf.format(localTime));
System.out.println("Local:" + localTime.toString() + "," + localTime.getTime() + " --> UTC time:"
+ gmtTime.toString() + "," + gmtTime.getTime());
// **** YOUR CODE **** END ****
// Convert UTC to Local Time
Date fromGmt = new Date(gmtTime.getTime() + TimeZone.getDefault().getOffset(localTime.getTime()));
System.out.println("UTC time:" + gmtTime.toString() + "," + gmtTime.getTime() + " --> Local:"
+ fromGmt.toString() + "-" + fromGmt.getTime());
Output:
Local:Tue Oct 15 12:19:40 CEST 2013,1381832380522 --> UTC time:Tue Oct 15 10:19:40 CEST 2013,1381825180000
UTC time:Tue Oct 15 10:19:40 CEST 2013,1381825180000 --> Local:Tue Oct 15 12:19:40 CEST 2013-1381832380000
I had the same probem a while ago, before starting using Symfony framework.
Just use a function __() which has arameters pageId (or objectId, objectTable described in #2), target language and an optional parameter of fallback (default) language. The default language could be set in some global config in order to have an easier way to change it later.
For storing the content in database i used following structure: (pageId, language, content, variables).
pageId would be a FK to your page you want to translate. if you have other objects, like news, galleries or whatever, just split it into 2 fields objectId, objectTable.
language - obviously it would store the ISO language string EN_en, LT_lt, EN_us etc.
content - the text you want to translate together with the wildcards for variable replacing. Example "Hello mr. %%name%%. Your account balance is %%balance%%."
variables - the json encoded variables. PHP provides functions to quickly parse these. Example "name: Laurynas, balance: 15.23".
you mentioned also slug field. you could freely add it to this table just to have a quick way to search for it.
Your database calls must be reduced to minimum with caching the translations. It must be stored in PHP array, because it is the fastest structure in PHP language. How you will make this caching is up to you. From my experience you should have a folder for each language supported and an array for each pageId. The cache should be rebuilt after you update the translation. ONLY the changed array should be regenerated.
i think i answered that in #2
your idea is perfectly logical. this one is pretty simple and i think will not make you any problems.
URLs should be translated using the stored slugs in the translation table.
Final words
it is always good to research the best practices, but do not reinvent the wheel. just take and use the components from well known frameworks and use them.
take a look at Symfony translation component. It could be a good code base for you.
You want rows where that condition is true so you need a comma:
data[data$Ozone > 14, ]
In my case, it was because I was trying to setup django-environ
and I missed an important step:
Note: In the instructions below .env.example and .env should be saved in the same folder as settings.py
I incorrectly assumed that .env
belonged in the root of my project. Moving it to the same folder as settings.py
fixed the problem.
This error message in the Python console was the clue that set me on the right path:
Warning: /Users/allen/PycharmProjects/myapp/myapp/.env doesn't exist - if you're not configuring your environment separately, create one.
'T'
and 'Z'
are considered here as constants. You need to pass Z
without the quotes. Moreover you need to specify the timezone in the input string.
Example : 2013-09-29T18:46:19-0700
And the format as "yyyy-MM-dd'T'HH:mm:ssZ"
PHP and MySQL have their own default timezone configurations. You should synchronize time between your data base and web application, otherwise you could run some issues.
Read this tutorial: How To Synchronize Your PHP and MySQL Timezones
Use this SimpleDateFormat formatDate = new SimpleDateFormat("hh:mm a");
Quick and dirty - Turn it off:
USE_TZ = False
in your settings.py
I have resolved it by deleting android-support-v4.jar
from my Project. Because appcompat_v7
already have a copy of it.
If you have already import appcompat_v7 but still the problem doesn't solve. then try it.

OP's solution to his problem, as he says, has dubious output. That code still shows confusion about representations of time. To clear up this confusion, and make code that won't lead to wrong times, consider this extension of what he did:
public static void _testDateFormatting() {
SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));
SimpleDateFormat sdfGMT2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");
sdfGMT2.setTimeZone(TimeZone.getTimeZone("GMT"));
SimpleDateFormat sdfLocal1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
SimpleDateFormat sdfLocal2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");
try {
Date d = new Date();
String s1 = d.toString();
String s2 = sdfLocal1.format(d);
// Store s3 or s4 in database.
String s3 = sdfGMT1.format(d);
String s4 = sdfGMT2.format(d);
// Retrieve s3 or s4 from database, using LOCAL sdf.
String s5 = sdfLocal1.parse(s3).toString();
//EXCEPTION String s6 = sdfLocal2.parse(s3).toString();
String s7 = sdfLocal1.parse(s4).toString();
String s8 = sdfLocal2.parse(s4).toString();
// Retrieve s3 from database, using GMT sdf.
// Note that this is the SAME sdf that created s3.
Date d2 = sdfGMT1.parse(s3);
String s9 = d2.toString();
String s10 = sdfGMT1.format(d2);
String s11 = sdfLocal2.format(d2);
} catch (Exception e) {
e.printStackTrace();
}
}
examining values in a debugger:
s1 "Mon Sep 07 06:11:53 EDT 2015" (id=831698113128)
s2 "2015.09.07 06:11:53" (id=831698114048)
s3 "2015.09.07 10:11:53" (id=831698114968)
s4 "2015.09.07 10:11:53 GMT+00:00" (id=831698116112)
s5 "Mon Sep 07 10:11:53 EDT 2015" (id=831698116944)
s6 -- omitted, gave parse exception
s7 "Mon Sep 07 10:11:53 EDT 2015" (id=831698118680)
s8 "Mon Sep 07 06:11:53 EDT 2015" (id=831698119584)
s9 "Mon Sep 07 06:11:53 EDT 2015" (id=831698120392)
s10 "2015.09.07 10:11:53" (id=831698121312)
s11 "2015.09.07 06:11:53 EDT" (id=831698122256)
sdf2 and sdfLocal2 include time zone, so we can see what is really going on. s1 & s2 are at 06:11:53 in zone EDT. s3 & s4 are at 10:11:53 in zone GMT -- equivalent to the original EDT time. Imagine we save s3 or s4 in a data base, where we are using GMT for consistency, so we can have times from anywhere in the world, without storing different time zones.
s5 parses the GMT time, but treats it as a local time. So it says "10:11:53" -- the GMT time -- but thinks it is 10:11:53 in local time. Not good.
s7 parses the GMT time, but ignores the GMT in the string, so still treats it as a local time.
s8 works, because now we include GMT in the string, and the local zone parser uses it to convert from one time zone to another.
Now suppose you don't want to store the zone, you want to be able to parse s3, but display it as a local time. The answer is to parse using the same time zone it was stored in -- so use the same sdf as it was created in, sdfGMT1. s9, s10, & s11 are all representations of the original time. They are all "correct". That is, d2 == d1. Then it is only a question of how you want to DISPLAY it. If you want to display what is stored in DB -- GMT time -- then you need to format it using a GMT sdf. Ths is s10.
So here is the final solution, if you don't want to explicitly store with " GMT" in the string, and want to display in GMT format:
public static void _testDateFormatting() {
SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));
try {
Date d = new Date();
String s3 = sdfGMT1.format(d);
// Store s3 in DB.
// ...
// Retrieve s3 from database, using GMT sdf.
Date d2 = sdfGMT1.parse(s3);
String s10 = sdfGMT1.format(d2);
} catch (Exception e) {
e.printStackTrace();
}
}
You can also add in callbacks - here I'm using Dropzone for Angular
dzCallbacks = {
'addedfile' : function(file){
$scope.btSend = false;
$scope.form.logoFile = file;
},
'success' : function(file, xhr){
$scope.btSend = true;
console.log(file, xhr);
},
'maxfilesexceeded': function(file) {
$timeout(function() {
file._removeLink.click();
}, 2000);
}
}
moment has updated the js lib as of 06/2018.
var newYork = moment.tz("2014-06-01 12:00", "America/New_York");
var losAngeles = newYork.clone().tz("America/Los_Angeles");
var london = newYork.clone().tz("Europe/London");
newYork.format(); // 2014-06-01T12:00:00-04:00
losAngeles.format(); // 2014-06-01T09:00:00-07:00
london.format(); // 2014-06-01T17:00:00+01:00
if you have freedom to use Angular5+, then better use datePipe feature there than the timezone function here. I have to use moment.js because my project limits to Angular2 only.
Further to what sqram was saying, Dropzone has an additional undocumented option, "hiddenInputContainer". All you have to do is set this option to the selector of the form you want the hidden file field to be appended to. And voila! The ".dz-hidden-input" file field that Dropzone normally adds to the body magically moves into your form. No altering the Dropzone source code.
Now while this works to move the Dropzone file field into your form, the field has no name. So you will need to add:
_this.hiddenFileInput.setAttribute("name", "field_name[]");
to dropzone.js after this line:
_this.hiddenFileInput = document.createElement("input");
around line 547.
You likely don't have a CA signed certificate installed in your SQL VM's trusted root store.
If you have Encrypt=True
in the connection string, either set that to off (not recommended), or add the following in the connection string:
TrustServerCertificate=True
SQL Server will create a self-signed certificate if you don't install one for it to use, but it won't be trusted by the caller since it's not CA-signed, unless you tell the connection string to trust any server cert by default.
Long term, I'd recommend leveraging Let's Encrypt to get a CA signed certificate from a known trusted CA for free, and install it on the VM. Don't forget to set it up to automatically refresh. You can read more on this topic in SQL Server books online under the topic of "Encryption Hierarchy", and "Using Encryption Without Validation".
Just a generic note. a way to keep it flexible.

to_date()
returns a date at 00:00:00, so you need to "remove" the minutes from the date you are comparing to:
select *
from table
where trunc(es_date) = TO_DATE('27-APR-12','dd-MON-yy')
You probably want to create an index on trunc(es_date)
if that is something you are doing on a regular basis.
The literal '27-APR-12'
can fail very easily if the default date format is changed to anything different. So make sure you you always use to_date()
with a proper format mask (or an ANSI literal: date '2012-04-27'
)
Although you did right in using to_date()
and not relying on implict data type conversion, your usage of to_date() still has a subtle pitfall because of the format 'dd-MON-yy'
.
With a different language setting this might easily fail e.g. TO_DATE('27-MAY-12','dd-MON-yy')
when NLS_LANG is set to german. Avoid anything in the format that might be different in a different language. Using a four digit year and only numbers e.g. 'dd-mm-yyyy'
or 'yyyy-mm-dd'
Check this:
function dateToLocalISO(date) {
const off = date.getTimezoneOffset()
const absoff = Math.abs(off)
return (new Date(date.getTime() - off*60*1000).toISOString().substr(0,23) +
(off > 0 ? '-' : '+') +
(absoff / 60).toFixed(0).padStart(2,'0') + ':' +
(absoff % 60).toString().padStart(2,'0'))
}
// Test it:
d = new Date()
dateToLocalISO(d)
// ==> '2019-06-21T16:07:22.181-03:00'
// Is similar to:
moment = require('moment')
moment(d).format('YYYY-MM-DDTHH:mm:ss.SSSZ')
// ==> '2019-06-21T16:07:22.181-03:00'
h/H = 12/24 hours means you will write hh:mm = 12 hours format and HH:mm = 24 hours format
The accepted answer is not necessarily correct. queuecomplete
will be called even when the selected file is larger than the max file size.
The proper event to use is successmultiple
or completemultiple
.
In your connection page put a code like this date_default_timezone_set("Africa/Johannesburg");
based on your current location.
Because I always struggle to remember, a quick summary of what each of these do:
>>> pd.Timestamp.now() # naive local time
Timestamp('2019-10-07 10:30:19.428748')
>>> pd.Timestamp.utcnow() # tz aware UTC
Timestamp('2019-10-07 08:30:19.428748+0000', tz='UTC')
>>> pd.Timestamp.now(tz='Europe/Brussels') # tz aware local time
Timestamp('2019-10-07 10:30:19.428748+0200', tz='Europe/Brussels')
>>> pd.Timestamp.now(tz='Europe/Brussels').tz_localize(None) # naive local time
Timestamp('2019-10-07 10:30:19.428748')
>>> pd.Timestamp.now(tz='Europe/Brussels').tz_convert(None) # naive UTC
Timestamp('2019-10-07 08:30:19.428748')
>>> pd.Timestamp.utcnow().tz_localize(None) # naive UTC
Timestamp('2019-10-07 08:30:19.428748')
>>> pd.Timestamp.utcnow().tz_convert(None) # naive UTC
Timestamp('2019-10-07 08:30:19.428748')
Still another solution:
timezone('utc', now())
The problem is that System. currentTimeMillis();
returns the number of milliseconds from 1970-01-01T00:00:00Z, but new Date()
gives the current local time. Adding the ZONE_OFFSET and DST_OFFSET from the Calendar class gives you the time in UTC.
Calendar rightNow = Calendar.getInstance();
// offset to add since we're not UTC
long offset = rightNow.get(Calendar.ZONE_OFFSET) +
rightNow.get(Calendar.DST_OFFSET);
long sinceMidnight = (rightNow.getTimeInMillis() + offset) %
(24 * 60 * 60 * 1000);
System.out.println(sinceMidnight + " milliseconds since midnight");
You're not using react native or react so forgive me this isn't a solution for you. - since this is a 7 year old post I'm pretty sure you figured it out by now ;)
But I was looking for something similar for react-native and it led me to this SO question. Incase anyone else winds up down the same road I thought I'd share my
use-moment-countdown
hook for react or react native: https://github.com/BrooklinJazz/use-moment-countdown.
For example you can make a 10 minute timer like so:
import React from 'react'
import { useCountdown } from 'use-moment-countdown'
const App = () => {
const {start, time} = useCountdown({m: 10})
return (
<div onClick={start}>
{time.format("hh:mm:ss")}
</div>
)
}
export default App

Also, note that the nearest-city approach may not yield the "correct" result, just an approximation.
Conversion To Windows Zones
Most of the methods listed will return an IANA time zone id. If you need to convert to a Windows time zone for use with the TimeZoneInfo
class in .NET, use the TimeZoneConverter library.
Don't use zone.tab
The tz database includes a file called zone.tab
. This file is primarily used to present a list of time zones for a user to pick from. It includes the latitude and longitude coordinates for the point of reference for each time zone. This allows a map to be created highlighting these points. For example, see the interactive map shown on the moment-timezone home page.
While it may be tempting to use this data to resolve the time zone from a latitude and longitude coordinates, consider that these are points - not boundaries. The best one could do would be to determine the closest point, which in many cases will not be the correct point.
Consider the following example:
The two squares represent different time zones, where the black dot in each square is the reference location, such as what can be found in zone.tab. The blue dot represents the location we are attempting to find a time zone for. Clearly, this location is within the orange zone on the left, but if we just look at closest distance to the reference point, it will resolve to the greenish zone on the right.
[
is a command (or a builtin in some shells). It must be separated by whitespace from the preceding statement:
elif [
//This Works just fine
DateTime dt = new DateTime();
Log.d("ts",String.valueOf(dt.now()));
dt=dt.plusYears(3);
dt=dt.minusDays(7);
Log.d("JODA DateTime",String.valueOf(dt));
Timestamp ts= new Timestamp(dt.getMillis());
Log.d("Coverted to java.sql.Timestamp",String.valueOf(ts));
May be this helps some one who are looking for multiple date formats one after the other by willingly or unexpectedly. Please find the code: I am using moment.js format function on a current date as (today is 29-06-2020) var startDate = moment(new Date()).format('MM/DD/YY'); Result: 06/28/20
what happening is it retains only the year part :20 as "06/28/20", after If I run the statement : new Date(startDate) The result is "Mon Jun 28 1920 00:00:00 GMT+0530 (India Standard Time)",
Then, when I use another format on "06/28/20": startDate = moment(startDate ).format('MM-DD-YYYY'); Result: 06-28-1920, in google chrome and firefox browsers it gives correct date on second attempt as: 06-28-2020. But in IE it is having issues, from this I understood we can apply one dateformat on the given date, If we want second date format, it should be apply on the fresh date not on the first date format result. And also observe that for first time applying 'MM-DD-YYYY' and next 'MM-DD-YY' is working in IE. For clear understanding please find my question in the link: Date went wrong when using Momentjs date format in IE 11
After making configurations, you can check by writing this command on terminal
sysctl -a | grep file
to convert a TimestampTZ in oracle, you do
TO_TIMESTAMP_TZ('2012-10-09 1:10:21 CST','YYYY-MM-DD HH24:MI:SS TZR')
at time zone 'region'

You should:
Read this https://docs.djangoproject.com/en/dev/howto/static-files/:
For local development, if you are using runserver or adding staticfiles_urlpatterns to your URLconf, you’re done with the setup – your static files will automatically be served at the default (for newly created projects) STATIC_URL of /static/.
And try:
~/tmp$ django-admin.py startproject myprj
~/tmp$ cd myprj/
~/tmp/myprj$ chmod a+x manage.py
~/tmp/myprj$ ./manage.py startapp myapp
Then add 'myapp'
to INSTALLED_APPS
(myprj/settings.py
).
~/tmp/myprj$ cd myapp/
~/tmp/myprj/myapp$ mkdir static
~/tmp/myprj/myapp$ echo 'alert("hello!");' > static/hello.js
~/tmp/myprj/myapp$ mkdir templates
~/tmp/myprj/myapp$ echo '<script src="{{ STATIC_URL }}hello.js"></script>' > templates/hello.html
Edit myprj/urls.py
:
from django.conf.urls import patterns, include, url
from django.views.generic import TemplateView
class HelloView(TemplateView):
template_name = "hello.html"
urlpatterns = patterns('',
url(r'^$', HelloView.as_view(), name='hello'),
)
And run it:
~/tmp/myprj/myapp$ cd ..
~/tmp/myprj$ ./manage.py runserver
It works!
A couple of answers already mention that moment-timezone is the way to go with named timezone. I just want to clarify something about this library that was pretty confusing to me. There is a difference between these two statements:
moment.tz(date, format, timezone)
moment(date, format).tz(timezone)
Assuming that a timezone is not specified in the date passed in:
The first code takes in the date and assumes the timezone is the one passed in. The second one will take date, assume the timezone from the browser and then change the time and timezone according to the timezone passed in.
Example:
moment.tz('2018-07-17 19:00:00', 'YYYY-MM-DD HH:mm:ss', 'UTC').format() // "2018-07-17T19:00:00Z"
moment('2018-07-17 19:00:00', 'YYYY-MM-DD HH:mm:ss').tz('UTC').format() // "2018-07-18T00:00:00Z"
My timezone is +5 from utc. So in the first case it does not change and it sets the date and time to have utc timezone.
In the second case, it assumes the date passed in is in -5, then turns it into UTC, and that's why it spits out the date "2018-07-18T00:00:00Z"
NOTE: The format parameter is really important. If omitted moment might fall back to the Date class which can unpredictable behaviors
Assuming the timezone is specified in the date passed in:
In this case they both behave equally
Even though now I understand why it works that way, I thought this was a pretty confusing feature and worth explaining.
Add in pom.xml:
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-test</artifactId>
<version>4.0.0.RC2</version>
</dependency>
and use org.springframework.security.test.web.servlet.request.SecurityMockMvcRequestPostProcessors
for authorization request.
See the sample usage at https://github.com/rwinch/spring-security-test-blog
(https://jira.spring.io/browse/SEC-2592).
Update:
4.0.0.RC2 works for spring-security 3.x. For spring-security 4 spring-security-test become part of spring-security (http://docs.spring.io/spring-security/site/docs/4.0.x/reference/htmlsingle/#test, version is the same).

I ran into this issue. Turns out I was including in the template, using the static
template tag, a file that did not exist anymore. A look in the logs showed me the problem.
I guess this is just one of many possible reasons for this kind of error.
Moral of the story: always log errors and always check logs.
In AngularJS, we update our models, and our views/templates update the DOM "automatically" (via built-in or custom directives).
$apply and $watch, both being Scope methods, are not related to the DOM.
The Concepts page (section "Runtime") has a pretty good explanation of the $digest loop, $apply, the $evalAsync queue and the $watch list. Here's the picture that accompanies the text:
Whatever code has access to a scope – normally controllers and directives (their link functions and/or their controllers) – can set up a "watchExpression" that AngularJS will evaluate against that scope. This evaluation happens whenever AngularJS enters its $digest loop (in particular, the "$watch list" loop). You can watch individual scope properties, you can define a function to watch two properties together, you can watch the length of an array, etc.
When things happen "inside AngularJS" – e.g., you type into a textbox that has AngularJS two-way databinding enabled (i.e., uses ng-model), an $http callback fires, etc. – $apply has already been called, so we're inside the "AngularJS" rectangle in the figure above. All watchExpressions will be evaluated (possibly more than once – until no further changes are detected).
When things happen "outside AngularJS" – e.g., you used bind() in a directive and then that event fires, resulting in your callback being called, or some jQuery registered callback fires – we're still in the "Native" rectangle. If the callback code modifies anything that any $watch is watching, call $apply to get into the AngularJS rectangle, causing the $digest loop to run, and hence AngularJS will notice the change and do its magic.
This is how Google recommends getting TimezoneOffset.
Calendar calendar = Calendar.getInstance(Locale.getDefault());
int offset = -(calendar.get(Calendar.ZONE_OFFSET) + calendar.get(Calendar.DST_OFFSET)) / (60 * 1000)
https://developer.android.com/reference/java/util/Date#getTimezoneOffset()
select convert_tz(now(),@@session.time_zone,'+05:30')
replace '+05:30' with desired timezone. see here - https://stackoverflow.com/a/3984412/2359994
to format into desired time format, eg:
select DATE_FORMAT(convert_tz(now(),@@session.time_zone,'+05:30') ,'%b %d %Y %h:%i:%s %p')
you will get similar to this -> Dec 17 2014 10:39:56 AM
Java:
int offset = TimeZone.getDefault().getRawOffset() + TimeZone.getDefault().getDSTSavings();
long now = System.currentTimeMillis() - offset;
Kotlin:
Int offset = TimeZone.getDefault()rawOffset + TimeZone.getDefault().dstSavings
Long now = System.currentTimeMillis() - offset
Note: This is an answer useful for Python's ElementTree standard library without using hardcoded namespaces.
To extract namespace's prefixes and URI from XML data you can use ElementTree.iterparse
function, parsing only namespace start events (start-ns):
>>> from io import StringIO
>>> from xml.etree import ElementTree
>>> my_schema = u'''<rdf:RDF xml:base="http://dbpedia.org/ontology/"
... xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
... xmlns:owl="http://www.w3.org/2002/07/owl#"
... xmlns:xsd="http://www.w3.org/2001/XMLSchema#"
... xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
... xmlns="http://dbpedia.org/ontology/">
...
... <owl:Class rdf:about="http://dbpedia.org/ontology/BasketballLeague">
... <rdfs:label xml:lang="en">basketball league</rdfs:label>
... <rdfs:comment xml:lang="en">
... a group of sports teams that compete against each other
... in Basketball
... </rdfs:comment>
... </owl:Class>
...
... </rdf:RDF>'''
>>> my_namespaces = dict([
... node for _, node in ElementTree.iterparse(
... StringIO(my_schema), events=['start-ns']
... )
... ])
>>> from pprint import pprint
>>> pprint(my_namespaces)
{'': 'http://dbpedia.org/ontology/',
'owl': 'http://www.w3.org/2002/07/owl#',
'rdf': 'http://www.w3.org/1999/02/22-rdf-syntax-ns#',
'rdfs': 'http://www.w3.org/2000/01/rdf-schema#',
'xsd': 'http://www.w3.org/2001/XMLSchema#'}
Then the dictionary can be passed as argument to the search functions:
root.findall('owl:Class', my_namespaces)
There is definitly a problem with the destination folder path.
Your above error message says, it wants to put the contents to a file in the directory /files/grantapps/
, which would be beyond your vhost
, but somewhere in the system (see the leading absolute slash )
You should double check:
/home/username/public_html/files/grantapps/
really present./home/username/public_html/files/grantapps/
Unfortunately, strptime()
can only handle the timezone configured by your OS, and then only as a time offset, really. From the documentation:
Support for the
%Z
directive is based on the values contained intzname
and whetherdaylight
is true. Because of this, it is platform-specific except for recognizing UTC and GMT which are always known (and are considered to be non-daylight savings timezones).
strftime()
doesn't officially support %z
.
You are stuck with python-dateutil
to support timezone parsing, I am afraid.

It is specific from your driver. You need to supply a parameter in your Java program to tell it the time zone you want to use.
java -Duser.timezone="America/New_York" GetCurrentDateTimeZone
Further this:
to_char(new_time(sched_start_time, 'CURRENT_TIMEZONE', 'NEW_TIMEZONE'), 'MM/DD/YY HH:MI AM')
May also be of value in handling the conversion properly. Taken from here

The class Date/Timestamp
represents a specific instant in time, with millisecond precision, since January 1, 1970, 00:00:00 GMT. So this time difference (from epoch to current time) will be same in all computers across the world with irrespective of Timezone.
Date/Timestamp
doesn't know about the given time is on which timezone.
If we want the time based on timezone we should go for the Calendar or SimpleDateFormat classes in java.
If you try to print a Date/Timestamp object using toString()
, it will convert and print the time with the default timezone of your machine.
So we can say (Date/Timestamp).getTime() object will always have UTC (time in milliseconds)
To conclude Date.getTime()
will give UTC time, but toString()
is on locale specific timezone, not UTC.
The below code gives you a date (time in milliseconds) with specified timezones. The only problem here is you have to give date in string format.
DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd HH:mm:ss");
dateFormatLocal.setTimeZone(timeZone);
java.util.Date parsedDate = dateFormatLocal.parse(date);
Use dateFormat.format
for taking input Date (which is always UTC), timezone and return date as String.
If you print the parsedDate
object, the time will be in default timezone.
But you can store the UTC time in DB like below.
Calendar calGMT = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
Timestamp tsSchedStartTime = new Timestamp (parsedDate.getTime());
if (tsSchedStartTime != null) {
stmt.setTimestamp(11, tsSchedStartTime, calGMT );
} else {
stmt.setNull(11, java.sql.Types.DATE);
}

Both pandas
and matplotlib.dates
use matplotlib.units
for locating the ticks.
But while matplotlib.dates
has convenient ways to set the ticks manually, pandas seems to have the focus on auto formatting so far (you can have a look at the code for date conversion and formatting in pandas).
So for the moment it seems more reasonable to use matplotlib.dates
(as mentioned by @BrenBarn in his comment).
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import matplotlib.dates as dates
idx = pd.date_range('2011-05-01', '2011-07-01')
s = pd.Series(np.random.randn(len(idx)), index=idx)
fig, ax = plt.subplots()
ax.plot_date(idx.to_pydatetime(), s, 'v-')
ax.xaxis.set_minor_locator(dates.WeekdayLocator(byweekday=(1),
interval=1))
ax.xaxis.set_minor_formatter(dates.DateFormatter('%d\n%a'))
ax.xaxis.grid(True, which="minor")
ax.yaxis.grid()
ax.xaxis.set_major_locator(dates.MonthLocator())
ax.xaxis.set_major_formatter(dates.DateFormatter('\n\n\n%b\n%Y'))

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);

Well, since you can currently only have one ngView directive... I use nested directive controls. This allows you to set up templating and inherit (or isolate) scopes among them. Outside of that I use ng-switch or even just ng-show to choose which controls I'm displaying based on what's coming in from $routeParams.
EDIT Here's some example pseudo-code to give you an idea of what I'm talking about. With a nested sub navigation.
Here's the main app page
<!-- primary nav -->
<a href="#/page/1">Page 1</a>
<a href="#/page/2">Page 2</a>
<a href="#/page/3">Page 3</a>
<!-- display the view -->
<div ng-view>
</div>
Directive for the sub navigation
app.directive('mySubNav', function(){
return {
restrict: 'E',
scope: {
current: '=current'
},
templateUrl: 'mySubNav.html',
controller: function($scope) {
}
};
});
template for the sub navigation
<a href="#/page/1/sub/1">Sub Item 1</a>
<a href="#/page/1/sub/2">Sub Item 2</a>
<a href="#/page/1/sub/3">Sub Item 3</a>
template for a main page (from primary nav)
<my-sub-nav current="sub"></my-sub-nav>
<ng-switch on="sub">
<div ng-switch-when="1">
<my-sub-area1></my-sub-area>
</div>
<div ng-switch-when="2">
<my-sub-area2></my-sub-area>
</div>
<div ng-switch-when="3">
<my-sub-area3></my-sub-area>
</div>
</ng-switch>
Controller for a main page. (from the primary nav)
app.controller('page1Ctrl', function($scope, $routeParams) {
$scope.sub = $routeParams.sub;
});
Directive for a Sub Area
app.directive('mySubArea1', function(){
return {
restrict: 'E',
templateUrl: 'mySubArea1.html',
controller: function($scope) {
//controller for your sub area.
}
};
});
Search till the seconds for the timestamp column in postgress
select * from "TableName" e
where timestamp >= '2020-08-08T13:00:00' and timestamp < '2020-08-08T17:00:00';
var i2 = JsonConvert.DeserializeObject(obj["id"].ToString(), type);
throws a parsing exception due to missing quotes around the first argument (I think). I got it to work by adding the quotes:
var i2 = JsonConvert.DeserializeObject("\"" + obj["id"].ToString() + "\"", type);
if you just need a timestamp in unix /epoch time, this one line works:
created_timestamp = int((datetime.datetime.now() - datetime.datetime(1970,1,1)).total_seconds())
>>> created_timestamp
1522942073L
and depends only on datetime
works in python2 and python3
The dat file has some lines of extra information before the actual data. Skip them with the skip
argument:
read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
header=TRUE, skip=3)
An easy way to check this if you are unfamiliar with the dataset is to first use readLines
to check a few lines, as below:
readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
n=10)
# [1] "Ozone data from CZ03 2009" "Local time: GMT + 0"
# [3] "" "Date Hour Value"
# [5] "01.01.2009 00:00 34.3" "01.01.2009 01:00 31.9"
# [7] "01.01.2009 02:00 29.9" "01.01.2009 03:00 28.5"
# [9] "01.01.2009 04:00 32.9" "01.01.2009 05:00 20.5"
Here, we can see that the actual data starts at [4]
, so we know to skip the first three lines.
If you really only wanted the Value
column, you could do that by:
as.vector(
read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
header=TRUE, skip=3)$Value)
Again, readLines
is useful for helping us figure out the actual name of the columns we will be importing.
But I don't see much advantage to doing that over reading the whole dataset in and extracting later.
I need to save the phone's timezone in the format [+/-]hh:mm
No, you don't. Offset on its own is not enough, you need to store the whole time zone name/id. For example I live in Oslo where my current offset is +02:00 but in winter (due to dst) it is +01:00. The exact switch between standard and summer time depends on factors you don't want to explore.
So instead of storing + 02:00
(or should it be + 01:00
?) I store "Europe/Oslo"
in my database. Now I can restore full configuration using:
TimeZone tz = TimeZone.getTimeZone("Europe/Oslo")
Want to know what is my time zone offset today?
tz.getOffset(new Date().getTime()) / 1000 / 60 //yields +120 minutes
However the same in December:
Calendar christmas = new GregorianCalendar(2012, DECEMBER, 25);
tz.getOffset(christmas.getTimeInMillis()) / 1000 / 60 //yields +60 minutes
Enough to say: store time zone name or id and every time you want to display a date, check what is the current offset (today) rather than storing fixed value. You can use TimeZone.getAvailableIDs()
to enumerate all supported timezone IDs.
You asked:
I was looking for a one-liner like:
Ask and ye shall receive. Convert from terrible legacy class Date
to its modern replacement, Instant
.
myJavaUtilDate.toInstant().toString()
2020-05-05T19:46:12.912Z
In Java 8 and later we have the new java.time package built in (Tutorial). Inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project.
The best solution is to sort your date-time objects rather than strings. But if you must work in strings, read on.
An Instant
represents a moment on the timeline, basically in UTC (see class doc for precise details). The toString
implementation uses the DateTimeFormatter.ISO_INSTANT
format by default. This format includes zero, three, six or nine digits digits as needed to display fraction of a second up to nanosecond precision.
String output = Instant.now().toString(); // Example: '2015-12-03T10:15:30.120Z'
If you must interoperate with the old Date
class, convert to/from java.time via new methods added to the old classes. Example: Date::toInstant
.
myJavaUtilDate.toInstant().toString()
You may want to use an alternate formatter if you need a consistent number of digits in the fractional second or if you need no fractional second.
Another route if you want to truncate fractions of a second is to use ZonedDateTime
instead of Instant
, calling its method to change the fraction to zero.
Note that we must specify a time zone for ZonedDateTime
(thus the name). In our case that means UTC. The subclass of ZoneID
, ZoneOffset
, holds a convenient constant for UTC. If we omit the time zone, the JVM’s current default time zone is implicitly applied.
String output = ZonedDateTime.now( ZoneOffset.UTC ).withNano( 0 ).toString(); // Example: 2015-08-27T19:28:58Z
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes. Hibernate 5 & JPA 2.2 support java.time.
Where to obtain the java.time classes?
UPDATE: The Joda -Time project is now in maintenance mode, with the team advising migration to the java.time classes.
I was looking for a one-liner
Easy if using the Joda-Time 2.3 library. ISO 8601 is the default formatting.
In the code example below, note that I am specifying a time zone rather than depending on the default time zone. In this case, I'm specifying UTC per your question. The Z
on the end, spoken as "Zulu", means no time zone offset from UTC.
// import org.joda.time.*;
String output = new DateTime( DateTimeZone.UTC );
Output…

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.
If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.
If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).
Please note: The first part of this answer is or version 1.x of pendulum. See below for a version 2.x answer.
I hope I'm not too late!
The pendulum library excels at this and other date-time calculations.
>>> import pendulum
>>> some_time_zones = ['Europe/Paris', 'Europe/Moscow', 'America/Toronto', 'UTC', 'Canada/Pacific', 'Asia/Macao']
>>> heres_a_time = '1996-03-25 12:03 -0400'
>>> pendulum_time = pendulum.datetime.strptime(heres_a_time, '%Y-%m-%d %H:%M %z')
>>> for tz in some_time_zones:
... tz, pendulum_time.astimezone(tz)
...
('Europe/Paris', <Pendulum [1996-03-25T17:03:00+01:00]>)
('Europe/Moscow', <Pendulum [1996-03-25T19:03:00+03:00]>)
('America/Toronto', <Pendulum [1996-03-25T11:03:00-05:00]>)
('UTC', <Pendulum [1996-03-25T16:03:00+00:00]>)
('Canada/Pacific', <Pendulum [1996-03-25T08:03:00-08:00]>)
('Asia/Macao', <Pendulum [1996-03-26T00:03:00+08:00]>)
Answer lists the names of the time zones that may be used with pendulum. (They're the same as for pytz.)
For version 2:
some_time_zones
is a list of the names of the time zones that might be used in a programheres_a_time
is a sample time, complete with a time zone in the form '-0400'show_time_zones
...
>>> import pendulum
>>> some_time_zones = ['Europe/Paris', 'Europe/Moscow', 'America/Toronto', 'UTC', 'Canada/Pacific', 'Asia/Macao']
>>> heres_a_time = '1996-03-25 12:03 -0400'
>>> pendulum_time = pendulum.from_format('1996-03-25 12:03 -0400', 'YYYY-MM-DD hh:mm ZZ')
>>> for tz in some_time_zones:
... tz, pendulum_time.in_tz(tz)
...
('Europe/Paris', DateTime(1996, 3, 25, 17, 3, 0, tzinfo=Timezone('Europe/Paris')))
('Europe/Moscow', DateTime(1996, 3, 25, 19, 3, 0, tzinfo=Timezone('Europe/Moscow')))
('America/Toronto', DateTime(1996, 3, 25, 11, 3, 0, tzinfo=Timezone('America/Toronto')))
('UTC', DateTime(1996, 3, 25, 16, 3, 0, tzinfo=Timezone('UTC')))
('Canada/Pacific', DateTime(1996, 3, 25, 8, 3, 0, tzinfo=Timezone('Canada/Pacific')))
('Asia/Macao', DateTime(1996, 3, 26, 0, 3, 0, tzinfo=Timezone('Asia/Macao')))
To remove a timezone (tzinfo) from a datetime object:
# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)
If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.
# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)
Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime
object to insert into the database. The solution is to convert your datetime.datetime
object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime
objects where one is timezone aware and another is timezone naive.
##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
arrowDt = arrowObj.to("utc").datetime
# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)
# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()
# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3
# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True
With the command:
sudo apt-get remove --purge mysql\*
you can delete anything related to packages named mysql. Those commands are only valid on debian / debian-based linux distributions (Ubuntu for example).
You can list all installed mysql packages with the command:
sudo dpkg -l | grep -i mysql
For more cleanup of the package cache, you can use the command:
sudo apt-get clean
Also, remember to use the command:
sudo updatedb
Otherwise the "locate" command will display old data.
To install mysql again, use the following command:
sudo apt-get install libmysqlclient-dev mysql-client
This will install the mysql client, libmysql and its headers files.
To install the mysql server, use the command:
sudo apt-get install mysql-server
As others have mentioned the underlying dict is unordered. However there are OrderedDict objects in python. ( They're built in in recent pythons, or you can use this: http://code.activestate.com/recipes/576693/ ).
I believe that newer pythons json implementations correctly handle the built in OrderedDicts, but I'm not sure (and I don't have easy access to test).
Old pythons simplejson implementations dont handle the OrderedDict objects nicely .. and convert them to regular dicts before outputting them.. but you can overcome this by doing the following:
class OrderedJsonEncoder( simplejson.JSONEncoder ):
def encode(self,o):
if isinstance(o,OrderedDict.OrderedDict):
return "{" + ",".join( [ self.encode(k)+":"+self.encode(v) for (k,v) in o.iteritems() ] ) + "}"
else:
return simplejson.JSONEncoder.encode(self, o)
now using this we get:
>>> import OrderedDict
>>> unordered={"id":123,"name":"a_name","timezone":"tz"}
>>> ordered = OrderedDict.OrderedDict( [("id",123), ("name","a_name"), ("timezone","tz")] )
>>> e = OrderedJsonEncoder()
>>> print e.encode( unordered )
{"timezone": "tz", "id": 123, "name": "a_name"}
>>> print e.encode( ordered )
{"id":123,"name":"a_name","timezone":"tz"}
Which is pretty much as desired.
Another alternative would be to specialise the encoder to directly use your row class, and then you'd not need any intermediate dict or UnorderedDict.
moment.js
is great but sometimes you don't want to pull a large number of dependencies for simple things.
The following works as well:
var tzoffset = (new Date()).getTimezoneOffset() * 60000; //offset in milliseconds
var localISOTime = (new Date(Date.now() - tzoffset)).toISOString().slice(0, -1);
// => '2015-01-26T06:40:36.181'
The slice(0, -1)
gets rid of the trailing Z
which represents Zulu timezone and can be replaced by your own.
You are putting there a two-digits year. The first century. And the Gregorian calendar started in the 16th century. I think you should add 2000 to the year.
Month in the function new GregorianCalendar(year, month, days)
is 0-based. Subtract 1 from the month there.
Change the body of the second function as follows:
String dateFormatted = null;
SimpleDateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
try {
dateFormatted = fmt.format(date);
}
catch ( IllegalArgumentException e){
System.out.println(e.getMessage());
}
return dateFormatted;
After debugging, you'll see that simply GregorianCalendar
can't be an argument of the fmt.format();
.
Really, nobody needs GregorianCalendar
as output, even you are told to return "a string".
Change the header of your format function to
public static String format(final Date date)
and make the appropriate changes. fmt.format()
will take the Date
object gladly.
NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];
or use
NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);
You can also make your own nodeJS endpoint, publish it with something like heroku, and access it
require("http").createServer(function (q,r) {
r.setHeader("accees-control-allow-origin","*")
r.end(Date.now())
}).listen(process.env.PORT || 80)
Then just access it on JS
fetch ("http://someGerokuApp")
.then(r=>r.text)
. then (r=>console.log(r))
This will still be relative to whatever computer the node app is hosted on, but perhaps you can get the location somehow and provide different endpoints fit the other timezones based on the current one (for example if the server happens to be in California then for a new York timezone just add 1000*60*60*3
milliseconds to Date.now() to add 3 hours)
For simplicity, if it's possible to get the location from the server and send it as a response header, you can just do the calculations for the different time zones in the client side
In fact using heroku they allow you to specify a region that it should be deployed at https://devcenter.heroku.com/articles/regions#specifying-a-region you can use this as reference..
EDIT just realized the timezone is in the date string itself, can just pay the whole thing as a header to be read by the client
require("http").createServer(function (q,r) {
var d= new Date()
r.setHeader("accees-control-allow-origin","*")
r.setHeader("zman", d.toString())
r.end(d.getTime())
}).listen(process.env.PORT || 80)
I seem to recall having to use @GeneratedValue(strategy = GenerationType.IDENTITY)
to get Hibernate to use 'serial' columns on PostgreSQL.
In java, DateFormatter by default uses DST,To avoid day Light saving (DST) you need to manually do a trick,
first you have to get the DST offset i.e. for how many millisecond DST applied, for ex somewhere DST is also for 45 minutes and for some places it is for 30 min
but in most cases DST is of 1 hour
you have to use Timezone object and check with the date whether it is falling under DST or not and then you have to manually add offset of DST into it. for eg:
TimeZone tz = TimeZone.getTimeZone("EST");
boolean isDST = tz.inDaylightTime(yourDateObj);
if(isDST){
int sec= tz.getDSTSavings()/1000;// for no. of seconds
Calendar cal= Calendar.getInstance();
cal.setTime(yourDateObj);
cal.add(Calendar.Seconds,sec);
System.out.println(cal.getTime());// your Date with DST neglected
}
I'm pretty sure you can't simply add on delete cascade
to an existing foreign key constraint. You have to drop the constraint first, then add the correct version. In standard SQL, I believe the easiest way to do this is to
on delete cascade
, and finallyRepeat for each foreign key you want to change.
But PostgreSQL has a non-standard extension that lets you use multiple constraint clauses in a single SQL statement. For example
alter table public.scores
drop constraint scores_gid_fkey,
add constraint scores_gid_fkey
foreign key (gid)
references games(gid)
on delete cascade;
If you don't know the name of the foreign key constraint you want to drop, you can either look it up in pgAdminIII (just click the table name and look at the DDL, or expand the hierarchy until you see "Constraints"), or you can query the information schema.
select *
from information_schema.key_column_usage
where position_in_unique_constraint is not null
You can use to toLocaleString() method for setting the timezone.
new Date().toLocaleString('en-US', { timeZone: 'Indian/Christmas' })
For India you can use "Indian/Christmas" and the following are the various timeZones,
"Antarctica/Davis",
"Asia/Bangkok",
"Asia/Hovd",
"Asia/Jakarta",
"Asia/Phnom_Penh",
"Asia/Pontianak",
"Asia/Saigon",
"Asia/Vientiane",
"Etc/GMT-7",
"Indian/Christmas"
As a supplementary, on Amazon EC2, what I need to do is:
sudo yum install freetype-devel
sudo yum install libpng-devel
sudo pip install matplotlib
JonSkeet has a good answer but as an alternative if you wanted to keep the result more portable you could convert the date into an ISO 8601 format which could then be read into most other frameworks but this may fall outside your requirements.
value.ToUniversalTime().ToString("O");
You can use this script. http://pellepim.bitbucket.org/jstz/
Fork or clone repository here. https://bitbucket.org/pellepim/jstimezonedetect
Once you include the script, you can get the list of timezones in - jstz.olson.timezones
variable.
And following code is used to determine client browser's timezone.
var tz = jstz.determine();
tz.name();
Enjoy jstz!
Dates constructed that way use the local timezone, making the constructed date incorrect. To set the timezone of a certain date object is to construct it from a date string that includes the timezone. (I had problems getting that to work in an older Android browser.)
Note that getTime()
returns milliseconds, not plain seconds.
For a UTC/Unix timestamp, the following should suffice:
Math.floor((new Date()).getTime() / 1000)
It will factor the current timezone offset into the result. For a string representation, David Ellis' answer works.
To clarify:
new Date(Y, M, D, h, m, s)
That input is treated as local time. If UTC time is passed in, the results will differ. Observe (I'm in GMT +02:00 right now, and it's 07:50):
> var d1 = new Date();
> d1.toUTCString();
"Sun, 18 Mar 2012 05:50:34 GMT" // two hours less than my local time
> Math.floor(d1.getTime()/ 1000)
1332049834
> var d2 = new Date( d1.getUTCFullYear(), d1.getUTCMonth(), d1.getUTCDate(), d1.getUTCHours(), d1.getUTCMinutes(), d1.getUTCSeconds() );
> d2.toUTCString();
"Sun, 18 Mar 2012 03:50:34 GMT" // four hours less than my local time, and two hours less than the original time - because my GMT+2 input was interpreted as GMT+0!
> Math.floor(d2.getTime()/ 1000)
1332042634
Also note that getUTCDate()
cannot be substituted for getUTCDay()
. This is because getUTCDate()
returns the day of the month; whereas, getUTCDay()
returns the day of the week.
"Z" doesn't stand for "Zulu"
I don't have any more information than the Wikipedia article cited by the two existing answers, but I believe the interpretation that "Z" stands for "Zulu" is incorrect. UTC time is referred to as "Zulu time" because of the use of Z to identify it, not the other way around. The "Z" seems to have been used to mark the time zone as the "zero zone", in which case "Z" unsurprisingly stands for "zero" (assuming the following information from Wikipedia is accurate):
Around 1950, a letter suffix was added to the zone description, assigning Z to the zero zone, and A–M (except J) to the east and N–Y to the west (J may be assigned to local time in non-nautical applications — zones M and Y have the same clock time but differ by 24 hours: a full day). These can be vocalized using the NATO phonetic alphabet which pronounces the letter Z as Zulu, leading to the use of the term "Zulu Time" for Greenwich Mean Time, or UT1 from January 1, 1972 onward.

You may also try to check the version of the Oracle jdbc driver and Oracle database. Just today I had this issue when using ojdbc6.jar (version 11.2.0.3.0) to connect to an Oracle 9.2.0.4.0 server. Replacing it with ojdbc6.jar version 11.1.0.7.0 solved the issue.
I also managed to make ojdbc6.jar version 11.2.0.3.0 connect without error, by adding oracle.jdbc.timezoneAsRegion=false
in file oracle/jdbc/defaultConnectionProperties.properties (inside the jar). Found this solution here (broken link)
Then, one can add -Doracle.jdbc.timezoneAsRegion=false
to the command line, or AddVMOption -Doracle.jdbc.timezoneAsRegion=false
in config files that use this notation.
You can also do this programmatically, e.g. with System.setProperty
.
In some cases you can add the environment variable on a per-connection basis if that's allowed (SQL Developer allows this in the "Advanced" connection properties; I verified it to work when connecting to a database that doesn't have the problem and using a database link to a database which has).
After searching for an hour or two ,I've found a simple solution below.
const date = new Date(`${date from client} GMT`);
inside double ticks, there is a date from client side plust GMT.
I'm first time commenting, constructive criticism will be welcomed.
i'm impressed of the deep discussion.
my 2 cents:
from datetime import datetime import time
the timestamp in utc is:
timestamp = \
(datetime.utcnow() - datetime(1970,1,1)).total_seconds()
or,
timestamp = time.time()
if now results from datetime.now(), in the same DST
utcoffset = (datetime.now() - datetime.utcnow()).total_seconds()
timestamp = \
(now - datetime(1970,1,1)).total_seconds() - utcoffset
The T is just a literal to separate the date from the time, and the Z means "zero hour offset" also known as "Zulu time" (UTC). If your strings always have a "Z" you can use:
SimpleDateFormat format = new SimpleDateFormat(
"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.US);
format.setTimeZone(TimeZone.getTimeZone("UTC"));
Or using Joda Time, you can use ISODateTimeFormat.dateTime()
.
Below is my solution to get date from miliseconds to date format. You have to use Joda Library to get this code run.
import java.util.GregorianCalendar;
import java.util.TimeZone;
import org.joda.time.DateTime;
import org.joda.time.DateTimeZone;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;
public class time {
public static void main(String args[]){
String str = "1431601084000";
long geTime= Long.parseLong(str);
GregorianCalendar calendar = new GregorianCalendar(TimeZone.getTimeZone("US/Central"));
calendar.setTimeInMillis(geTime);
DateTime jodaTime = new DateTime(geTime,
DateTimeZone.forTimeZone(TimeZone.getTimeZone("US/Central")));
DateTimeFormatter parser1 = DateTimeFormat.forPattern("yyyy-MM-dd");
System.out.println("Get Time : "+parser1.print(jodaTime));
}
}
before you get too excited this was written in 2011
if I were to do this these days I would use Intl.DateTimeFormat. Here is a link to give you an idea of what type of support this had in 2011
Date.getTimezoneOffset()
The getTimezoneOffset() method returns the time difference between Greenwich Mean Time (GMT) and local time, in minutes.
For example, If your time zone is GMT+2, -120 will be returned.
Note: This method is always used in conjunction with a Date object.
var d = new Date()
var gmtHours = -d.getTimezoneOffset()/60;
document.write("The local time zone is: GMT " + gmtHours);
//output:The local time zone is: GMT 11
There can be three reasons behind this error.
Unfortunately, setting process.env.TZ
doesn't work really well - basically it's indeterminate when the change will be effective).
So setting the system's timezone before starting node is your only proper option.
However, if you can't do that, it should be possible to use node-time as a workaround: get your times in local or UTC time, and convert them to the desired timezone. See How to use timezone offset in Nodejs? for details.
I have created some simple function you can use to convert time to any timezone :
function convertTimeToLocal($datetime,$timezone='Europe/Dublin') {
$given = new DateTime($datetime, new DateTimeZone("UTC"));
$given->setTimezone(new DateTimeZone($timezone));
$output = $given->format("Y-m-d"); //can change as per your requirement
return $output;
}
From MSDN
ReadOnlyCollection<TimeZoneInfo> zones = TimeZoneInfo.GetSystemTimeZones();
Console.WriteLine("The local system has the following {0} time zones", zones.Count);
foreach (TimeZoneInfo zone in zones)
Console.WriteLine(zone.Id);
I had a similar issue with Eclipse and the same steps as Sanders did solve it. It happens because the proxy restricts call to maven repository
D:\Maven\apache-maven-3.0.4-bin\apache-maven-3.0.4\conf
(ie your maven installation folder) settings.xml
and paste it in .m2
folder, which is in the users folder of your windows machine.Something like this:
<proxies>
<!-- proxy
Specification for one proxy, to be used in connecting to the network.
-->
<proxy>
<active>true</active>
<protocol>http</protocol>
<username>your username</username>
<password>password</password>
<host>proxy.host.net</host>
<port>80</port>
</proxy>
</proxies>
Please take care that the epoch time is in second and Date object accepts Long value which is in milliseconds. Hence you would have to multiply epoch value with 1000 to use it as long value . Like below :-
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");
sdf.setTimeZone(TimeZone.getTimeZone(timeZone));
Long dateLong=Long.parseLong(sdf.format(epoch*1000));
I needed the offset that not only included day light savings time but as a numerial. Here is the code that I used in case someone is looking for an example.
I get a response of "3.5" (3:30') which is what I would expect in Tehran , Iran in winter and "4.5" (4:30') for summer .
I also needed it as a string so I could post it to a server so you may not need the last line.
for getting currect time zone :
TimeZone tz = TimeZone.getDefault();
Date now = new Date();
//Import part : x.0 for double number
double offsetFromUtc = tz.getOffset(now.getTime()) / 3600000.0;
String m2tTimeZoneIs = Double.parseDouble(offsetFromUtc);
Understanding how computer time works is very important. With that said I agree that if an API is created to help you process computer time like real time then it should work in such a way that allows you to treat it like real time. For the most part this is the case but there are some major oversights which do need attention.
Anyway I digress!! If you have your UTC offset (better to work in UTC than GMT offsets) you can calculate the time in milliseconds and add that to your timestamp. Note that an SQL Timestamp may vary from a Java timestamp as the way the elapse from the epoch is calculated is not always the same - dependant on database technologies and also operating systems.
I would advise you to use System.currentTimeMillis() as your time stamps as these can be processed more consistently in java without worrying about converting SQL Timestamps to java Date objects etc.
To calculate your offset you can try something like this:
Long gmtTime =1317951113613L; // 2.32pm NZDT
Long timezoneAlteredTime = 0L;
if (offset != 0L) {
int multiplier = (offset*60)*(60*1000);
timezoneAlteredTime = gmtTime + multiplier;
} else {
timezoneAlteredTime = gmtTime;
}
Calendar calendar = new GregorianCalendar();
calendar.setTimeInMillis(timezoneAlteredTime);
DateFormat formatter = new SimpleDateFormat("dd MMM yyyy HH:mm:ss z");
formatter.setCalendar(calendar);
formatter.setTimeZone(TimeZone.getTimeZone(timeZone));
String newZealandTime = formatter.format(calendar.getTime());
I hope this is helpful!
JDBC uses a so-called "connection URL", so you can escape "+" by "%2B", that is
useTimezone=true&serverTimezone=GMT%2B8
You can always check this maintained list to timezones
Have you tried this in your application.properties?
spring.jackson.time-zone= # Time zone used when formatting dates. For instance `America/Los_Angeles`
Simply floating both elements left achieves the same result.

The number of connection attempts (successful or not) to the MySQL server.
You can see the number of active connections either through the Threads_connected

When you want to destroy a session completely, you need to do more then just
session_destroy();
First, you should unset any session variables. Then you should destroy the session followed by closing the write of the session. This can be done by the following:
<?php
session_start();
unset($_SESSION);
session_destroy();
session_write_close();
header('Location: /');
die;
?>
The reason you want have a separate script for a logout is so that you do not accidently execute it on the page. So make a link to your logout script, then the header will redirect to the root of your site.
Edit:
You need to remove the () from your exit code near the top of your script. it should just be
exit;
Ok. This is an ancient history, but may be my solution could be useful for you or another developers. If I don't want an user press back key in a page (lets say page B called from an page A) and go back to last page (page A), I do next steps:
First, on page A, instead call next page using window.location.href
or window.location.replace
, I make a call using two commands: window.open
and window.close
example on page A:
<a href="#"
onclick="window.open('B.htm','B','height=768,width=1024,top=0,left=0,menubar=0,
toolbar=0,location=0,directories=0,scrollbars=1,status=0');
window.open('','_parent','');
window.close();">
Page B</a>;
All modifiers on window open are just to make up the resulting page. This will open a new window (popWindow) without posibilities of use the back key, and will close the caller page (Page A)
Second: On page B you can use the same proccess if you want this page do the same thing.
Well. This needs the user accept you can open popup windows, but in a controlled system, as if you are programming pages for your work or client, this is easily recommended for the users. Just accept the site as trusted.
List<String> list = Arrays.asList(array);
The list returned will be backed by the array, it acts like a bridge, so it will be fixed-size.
Another approach is to generate an 100 items array with ascending numbers and sort it randomly. This leads actually to a really short and (in my opinion) simple snippet.
const numbers = Array(100).fill().map((_, index) => index + 1);_x000D_
numbers.sort(() => Math.random() - 0.5);_x000D_
console.log(numbers.slice(0, 8));
_x000D_
That work sharp for me
SELECT *
FROM [dbo].[table1] t1
LEFT JOIN [dbo].[table2] t2 ON t1.[t1_ID] = t2.[t2_ID]
WHERE t2.[t2_ID] IS NULL
One solution is to actually use an integer array instead of separate test
strings:
You could loop parse the response from JOptionPane.showInputDialog
into the individual elements of the array.
Arrays.sort
could be used to sort them to allow you to pick out the 2 highest values.
The average can be easily calculated then by adding these 2 values & dividing by 2.
int[] testScore = new int[3];
for (int i = 0; i < testScore.length; i++) {
testScore[i] = Integer.parseInt(JOptionPane.showInputDialog("Please input mark for test " + i + ": "));
}
Arrays.sort(testScore);
System.out.println("Average: " + (testScore[1] + testScore[2])/2.0);
I solve this problem by mixing the solutions above.
sink("/Users/my/myTest.dat")
writeLines(unlist(lapply(k, paste, collapse=" ")))
sink()
I think it works well
I'd like to put the entire database under version control, what database engine can I use so that I can put the actual database under version control instead of its dump?
This is not database engine dependent. By Microsoft SQL Server there are lots of version controlling programs. I don't think that problem can be solved with git, you have to use a pgsql specific schema version control system. I don't know whether such a thing exists or not...
It's worth noting that if your error is due to .htaccess, for example a missing rewrite_module, you'll still see the 500 internal server error.
lapsList() {
return this.state.laps.map((data) => {
return (
<View><Text>{data.time}</Text></View>
)
})
}
You forgot to return the map. this code will resolve the issue.
Here are some main key differences between constructor and method in java
It may be easier. Try to think like this:
:
// 'www.dev.yyy.com'
// 'xxx.foo.pl'
var url = "xxx.foo.pl";
switch (url.match(/\..*.\./)[0]){
case ".dev.yyy." :
console.log("xxx.dev.yyy.com");break;
case ".some.":
console.log("xxx.foo.pl");break;
} //end switch
Tomalak already gave you a correct answer, but I would like to add that most of the times when you would like to know the VBA code needed to do a certain action in the user interface it is a good idea to record a macro.
In this case click Record Macro on the developer tab of the Ribbon, freeze the top row and then stop recording. Excel will have the following macro recorded for you which also does the job:
With ActiveWindow
.SplitColumn = 0
.SplitRow = 1
End With
ActiveWindow.FreezePanes = True
Some interesting timings regarding all these methods. If you have Gigabit connections, you should not use the /z flag or it will kill your connection speed. Robocopy or dism are the only tools that go full speed and show a progress bar. wdscase is for multicasting off a WDS server and might be faster if you are imaging 5+ computers. To get the 1:17 timing, I was maxing out the Gigabit connection at 920Mbps so you won't get that on two connections at once. Also take note that exporting the small wim index out of the larger wim file too longer than just copying the whole thing.
Model Exe OS switches index size time link speed
8760w dism Win8 /export-wim index 1 6.27GB 2:21 link 1Gbps

6305 VBS.copy Winpe32 Wim 7.92 1:21 link 1Gbps
6305 robocopy Winpe32 Wim 7.92 1:17 link 1Gbps
If you don't have robocopy.exe available, why not run it from the network share you are copying your files from? In my case, I prefer to do that so I don't have to rebuild my WinPE boot.wim file every time I want to make a change and then update dozens of flash drives.
The cleanest fastest way:

No, how you are doing it is correct.
http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.2
you are probably doing it correct, only the dashboard shows just the higher ID taken, and thus the number of "active" nodes, relationships, although there are none. it is just informative.
to be sure you have an empty graph, run this command:
START n=node(*) return count(n);
START r=rel(*) return count(r);
if both give you 0, your deletion was succesfull.
There are a set of available properties to all Maven projects.
From Introduction to the POM:
project.basedir
: The directory that the current project resides in.
This means this points to where your Maven projects resides on your system. It corresponds to the location of the pom.xml
file. If your POM is located inside /path/to/project/pom.xml
then this property will evaluate to /path/to/project
.
Some properties are also inherited from the Super POM, which is the case for project.build.directory
. It is the value inside the <project><build><directory>
element of the POM. You can get a description of all those values by looking at the Maven model. For project.build.directory
, it is:
The directory where all files generated by the build are placed. The default value is
target
.
This is the directory that will hold every generated file by the build.
if you use jQuery, its quite simple. Here you go
$(document).keypress(
function(event){
if (event.which == '13') {
event.preventDefault();
}
});
Put in the URL bar and then click enter:
javascript:alert(document.title);
You can select and copy the text from the alert depending on the website and the web browser you are using.

Pickle uses different protocols
to convert your data to a binary stream.
In python 2 there are 3 different protocols (0
, 1
, 2
) and the default is 0
.
In python 3 there are 5 different protocols (0
, 1
, 2
, 3
, 4
) and the default is 3
.
You must specify in python 3 a protocol lower than 3
in order to be able to load the data in python 2. You can specify the protocol
parameter when invoking pickle.dump
.

This is not a correct method of updating record in SQL:
command.CommandText = "UPDATE Student(LastName, FirstName, Address, City) VALUES (@ln, @fn, @add, @cit) WHERE LastName='" + lastName + "' AND FirstName='" + firstName+"'";
You should write it like this:
command.CommandText = "UPDATE Student
SET Address = @add, City = @cit Where FirstName = @fn and LastName = @add";
Then you add the parameters same as you added them for the insert operation.

This snippet uses canvas.clientWidth and canvas.clientHeight rather than window.innerWidth and window.innerHeight to make the snippet run inside a complex layout correctly. However, it works for full window too if you just put it in a div that uses full window. It's more flexible this way.
The snippet uses the newish window.requestAnimationFrame to repeatedly resize the canvas every frame. If you can't use this, use setTimeout instead. Also, this is inefficient. To make it more efficient, store the clientWidth and clientHeight and only recalculate and redraw when clientWidth and clientHeight change.
The idea of a "reference" resolution lets you write all of your draw commands using one resolution... and it will automatically adjust to the client size without you having to change the drawing code.
The snippet is self explanatory, but if you prefer it explained in English: https://medium.com/@doomgoober/resizing-canvas-vector-graphics-without-aliasing-7a1f9e684e4d

No. You can't. But it is very possible in Scala:
class Foo {val bar = "a"}
class Bar {val foo = "b"}
To get the definition of the SQL codes, the easiest way is to use db2 cli!
at the unix or dos command prompt, just type
db2 "? SQL302"
this will give you the required explanation of the particular SQL code that you normally see in the java exception or your db2 sql output :)
hope this helped.
ianhanniballake is right. You can get all the functionality of Activity
from FragmentActivity
. In fact, FragmentActivity
has more functionality.
Using FragmentActivity
you can easily build tab and swap
format. For each tab you can use different Fragment
(Fragments
are reusable). So for any FragmentActivity
you can reuse the same Fragment
.
Still you can use Activity
for single pages like list down something and edit element of the list in next page.
Also remember to use Activity
if you are using android.app.Fragment
; use FragmentActivity
if you are using android.support.v4.app.Fragment
. Never attach a android.support.v4.app.Fragment
to an android.app.Activity
, as this will cause an exception to be thrown.
You could try using HTML5s sessionStorage it lasts for the duration on the page session. A page session lasts for as long as the browser is open and survives over page reloads and restores. Opening a page in a new tab or window will cause a new session to be initiated.
sessionStorage.setItem("username", "John");
https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#sessionStorage
Browser Compatibility https://code.google.com/p/sessionstorage/ compatible with every A-grade browser, included iPhone or Android. http://www.nczonline.net/blog/2009/07/21/introduction-to-sessionstorage/
An alternative to substr
is to split the string into a list of single characters and process that:
N <- 2
sapply(strsplit(x, ""), function(x, n) paste(tail(x, n), collapse = ""), N)
jQlite (angular's "jQuery" port) doesn't support lookup by classes.
One solution would be to include jQuery in your app.
Another is using QuerySelector
or QuerySelectorAll
:
link: function(scope, element, attrs) {
console.log(element[0].querySelector('.list-scrollable'))
}
We use the first item in the element
array, which is the HTML element. element.eq(0)
would yield the same.
LaTeX will usually not indent the first paragraph of a section. This is standard typographical practice. However, if you really want to override this default setting, use the package indentfirst available on CTAN.
For more detailed textual output, please try:
git log --graph --date-order -C -M --pretty=format:"<%h> %ad [%an] %Cgreen%d%Creset %s" --all --date=short
You can write alias in $HOME/.gitconfig
[alias]
graph = log --graph --date-order -C -M --pretty=format:\"<%h> %ad [%an] %Cgreen%d%Creset %s\" --all --date=short
I built on Guilhermes answer, but I preserve the position of the cursor and also treat the periods differently - this way if a user is typing after the period, it does not affect the numbers before the period I find that this gives a very smooth input.
[yourtextfield].addTextChangedListener(new TextWatcher()
{
NumberFormat currencyFormat = NumberFormat.getCurrencyInstance();
private String current = "";
@Override
public void onTextChanged(CharSequence s, int start, int before, int count)
{
if(!s.toString().equals(current))
{
[yourtextfield].removeTextChangedListener(this);
int selection = [yourtextfield].getSelectionStart();
// We strip off the currency symbol
String replaceable = String.format("[%s,\\s]", NumberFormat.getCurrencyInstance().getCurrency().getSymbol());
String cleanString = s.toString().replaceAll(replaceable, "");
double price;
// Parse the string
try
{
price = Double.parseDouble(cleanString);
}
catch(java.lang.NumberFormatException e)
{
price = 0;
}
// If we don't see a decimal, then the user must have deleted it.
// In that case, the number must be divided by 100, otherwise 1
int shrink = 1;
if(!(s.toString().contains(".")))
{
shrink = 100;
}
// Reformat the number
String formated = currencyFormat.format((price / shrink));
current = formated;
[yourtextfield].setText(formated);
[yourtextfield].setSelection(Math.min(selection, [yourtextfield].getText().length()));
[yourtextfield].addTextChangedListener(this);
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after)

The simpler option is just using ts(1)
from moreutils (fairly standard on most distros).
$ ping 1.1.1.1 | ts

Allows for the same strftime format strings as the shell/date
workaround.
Use: "%.2f"
or variations on that.
See the POSIX spec for an authoritative specification of the printf()
format strings. Note that it separates POSIX extras from the core C99 specification. There are some C++ sites which show up in a Google search, but some at least have a dubious reputation, judging from comments seen elsewhere on SO.
Since you're coding in C++, you should probably be avoiding printf()
and its relatives.
This example may help:

Subclass UIBarButtonItem
.
Make sure the button in Interface Builder is set to HidableBarButtonItem
.
Make an outlet from the button to the view controller. From the view controller you can then hide/show the button by calling setHidden:
HidableBarButtonItem.h
#import <UIKit/UIKit.h>
@interface HidableBarButtonItem : UIBarButtonItem
@property (nonatomic) BOOL hidden;
@end
HidableBarButtonItem.m
#import "HidableBarButtonItem.h"
@implementation HidableBarButtonItem
- (void)setHidden:(BOOL const)hidden {
_hidden = hidden;
self.enabled = hidden ? YES : NO;
self.tintColor = hidden ? [UIApplication sharedApplication].keyWindow.tintColor : [UIColor clearColor];
}
@end
Actually the Read
method iterating over records in a result set. In your case - over table rows. So you still can use it.
You can also use the subset function:
data <- subset(data, select=c(3,2,1))
You should better use the [] operator as in the other answers, but it may be useful to know that you can do a subset and a column reorder operation in a single command.
Update:
You can also use the select function from the dplyr package:
data = data %>% select(Time, out, In, Files)
I am not sure about the efficiency, but thanks to dplyr's syntax this solution should be more flexible, specially if you have a lot of columns. For example, the following will reorder the columns of the mtcars dataset in the opposite order:
mtcars %>% select(carb:mpg)
And the following will reorder only some columns, and discard others:
mtcars %>% select(mpg:disp, hp, wt, gear:qsec, starts_with('carb'))
Read more about dplyr's select syntax.
Just as an FYI - "best" questions aren't the norm at SO, but I will give you a list of options, just as a service.
OK then. These two are the ones I used:
and then there is always Eclipse.

Well, Sublime Text 2 is the one to heavily consider. Heavily.
public static class ExceptByProperty
{
public static List<T> ExceptBYProperty<T, TProperty>(this List<T> list, List<T> list2, Expression<Func<T, TProperty>> propertyLambda)
{
Type type = typeof(T);
MemberExpression member = propertyLambda.Body as MemberExpression;
if (member == null)
throw new ArgumentException(string.Format(
"Expression '{0}' refers to a method, not a property.",
propertyLambda.ToString()));
PropertyInfo propInfo = member.Member as PropertyInfo;
if (propInfo == null)
throw new ArgumentException(string.Format(
"Expression '{0}' refers to a field, not a property.",
propertyLambda.ToString()));
if (type != propInfo.ReflectedType &&
!type.IsSubclassOf(propInfo.ReflectedType))
throw new ArgumentException(string.Format(
"Expresion '{0}' refers to a property that is not from type {1}.",
propertyLambda.ToString(),
type));
Func<T, TProperty> func = propertyLambda.Compile();
var ids = list2.Select<T, TProperty>(x => func(x)).ToArray();
return list.Where(i => !ids.Contains(((TProperty)propInfo.GetValue(i, null)))).ToList();
}
}
public class testClass
{
public int ID { get; set; }
public string Name { get; set; }
}
For Test this:
List<testClass> a = new List<testClass>();
List<testClass> b = new List<testClass>();
a.Add(new testClass() { ID = 1 });
a.Add(new testClass() { ID = 2 });
a.Add(new testClass() { ID = 3 });
a.Add(new testClass() { ID = 4 });
a.Add(new testClass() { ID = 5 });
b.Add(new testClass() { ID = 3 });
b.Add(new testClass() { ID = 5 });
a.Select<testClass, int>(x => x.ID);
var items = a.ExceptBYProperty(b, u => u.ID);
Use the -I
flag to gcc properly.
gcc -I/path/to/openssl/ -o Opentest -lcrypto Opentest.c
The -I
should point to the directory containing the openssl
folder.
What I did is first check what are the running processes by
SELECT * FROM pg_stat_activity WHERE state = 'active';
Find the process you want to kill, then type:
SELECT pg_cancel_backend(<pid of the process>)
This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.
If the process cannot be killed, try:
SELECT pg_terminate_backend(<pid of the process>)
Best practice is to mark function async void
only if it is fire and forget method, if you want to await on, you should mark it as async Task
.
In case if you still want to await, then wrap it like so await Task.Run(() => blah())
I am new in Swift 3, but looking the String
(index) syntax for analogy I think that index is like a "pointer" constrained to string and Int can help as an independent object. Using the base + offset syntax , then we can get the i-th character from string with the code bellow:
let s = "abcdefghi"
let i = 2
print (s[s.index(s.startIndex, offsetBy:i)])
// print c
For a range of characters ( indexes) from string using String (range) syntax we can get from i-th to f-th characters with the code bellow:
let f = 6
print (s[s.index(s.startIndex, offsetBy:i )..<s.index(s.startIndex, offsetBy:f+1 )])
//print cdefg
For a substring (range) from a string using String.substring (range) we can get the substring using the code bellow:
print (s.substring (with:s.index(s.startIndex, offsetBy:i )..<s.index(s.startIndex, offsetBy:f+1 ) ) )
//print cdefg
Notes:
The i-th and f-th begin with 0.
To f-th, I use offsetBY: f + 1, because the range of subscription use ..< (half-open operator), not include the f-th position.
Of course must include validate errors like invalid index.
I believe that you're looking for numpy.split
or possibly numpy.array_split
if the number of sections doesn't need to divide the size of the array properly.
Personally, I just use JSON to convert things to strings and back. Strings I understand.
import json
s = [('yellow', 1), ('blue', 2), ('yellow', 3), ('blue', 4), ('red', 1)]
mydict = {}
hash = json.dumps(s)
mydict[hash] = "whatever"
print mydict
#{'[["yellow", 1], ["blue", 2], ["yellow", 3], ["blue", 4], ["red", 1]]': 'whatever'}
As per Nawfal's answer, IF statements need to be in a procedure. I found this post that shows a brilliant example of using your script in a procedure while still developing and testing. Basically, you create, call then drop the procedure:
Following code worked for me:
public function jsonSerialize()
{
return get_object_vars($this);
}
There are several situations that will give you this particular error. In the case of the OP there was a value defined explicitly as a string. So I have to assume that maybe this came from a dropdown, or web service or raw JSON string.
In that case a simple cast <Fruit> fruitString
or fruitString as Fruit
is the only solution (see other answers). You wouldn't ever be able to improve on this at compile time. [Edit: See my other answer about <const>
] !
However it's very easy to run into this same error when using constants in your code that aren't ever intended to be of type string. My answer focuses on that second scenario:
First of all: Why are 'magic' string constants often better than an enum?
Fortunately when you define:
export type FieldErrorType = 'none' | 'missing' | 'invalid'
...you're actually defining a union of types where 'missing'
is actually a type!
I often run into the 'not assignable' error if I have a string like 'banana'
in my typescript and the compiler thinks I meant it as a string, whereas I really wanted it to be of type banana
. How smart the compiler is able to be will depend on the structure of your code.
Here's an example of when I got this error today:
// this gives me the error 'string is not assignable to type FieldErrorType'
fieldErrors: [ { fieldName: 'number', error: 'invalid' } ]
As soon as I found out that 'invalid'
or 'banana'
could be either a type or a string I realized I could just assert a string into that type. Essentially cast it to itself, and tell the compiler no I don't want this to be a string!
// so this gives no error, and I don't need to import the union type too
fieldErrors: [ { fieldName: 'number', error: <'invalid'> 'invalid' } ]
FieldErrorType
(or Fruit
)// why not do this?
fieldErrors: [ { fieldName: 'number', error: <FieldErrorType> 'invalid' } ]
It's not compile time safe:
<FieldErrorType> 'invalidddd'; // COMPILER ALLOWS THIS - NOT GOOD!
<FieldErrorType> 'dog'; // COMPILER ALLOWS THIS - NOT GOOD!
'dog' as FieldErrorType; // COMPILER ALLOWS THIS - NOT GOOD!
Why? This is typescript so <FieldErrorType>
is an assertion and you are telling the compiler a dog is a FieldErrorType! And the compiler will allow it!
BUT if you do the following, then the compiler will convert the string to a type
<'invalid'> 'invalid'; // THIS IS OK - GOOD
<'banana'> 'banana'; // THIS IS OK - GOOD
<'invalid'> 'invalidddd'; // ERROR - GOOD
<'dog'> 'dog'; // ERROR - GOOD
Just watch out for stupid typos like this:
<'banana'> 'banan'; // PROBABLY WILL BECOME RUNTIME ERROR - YOUR OWN FAULT!
Another way to solve the problem is by casting the parent object:
My definitions were as follows:
export type FieldName = 'number' | 'expirationDate' | 'cvv'; export type FieldError = 'none' | 'missing' | 'invalid'; export type FieldErrorType = { field: FieldName, error: FieldError };
Let's say we get an error with this (the string not assignable error):
fieldErrors: [ { field: 'number', error: 'invalid' } ]
We can 'assert' the whole object as a FieldErrorType
like this:
fieldErrors: [ <FieldErrorType> { field: 'number', error: 'invalid' } ]
Then we avoid having to do <'invalid'> 'invalid'
.
But what about typos? Doesn't <FieldErrorType>
just assert whatever is on the right to be of that type. Not in this case - fortunately the compiler WILL complain if you do this, because it's clever enough to know it's impossible:
fieldErrors: [ <FieldErrorType> { field: 'number', error: 'dog' } ]
HashSet
don't maintain the order of insertion item

set.add("ab");
for(String value : set){
System.out.println(value);
}

This error happens because of your Jre version of Eclipse and Tomcat are mismatched ..either change eclipse one to tomcat one or ViceVersa..
Both should be same ..Java version
mismatched ..Check it
You could do:
sub("*\\.[0-9]", "", a)
or
library(stringr)
str_sub(a, start=1, end=-3)
First, before creating project, configure Eclipse syntax parser:
Window
-> Preferences
-> C/C++
-> Build
-> Settings
-> Discovery
-> CDT GCC Build-in Compiler Settings
in the text box entitled Command to get compiler specs
append -std=c++11
Now you can create project, configuration depends on what kind of project you created:
For project created as: File -> New -> Project -> C/C++ -> C++ Project
Right click on created project and open
Properties
-> C/C++ Build
-> Settings
-> Tool Settings
-> GCC C++ Compiler
-> Dialect
Put -std=c++11
into text box entitled other dialect flags
or select ISO C++11
from the Language standard
drop down.
For CMake project
Generate eclipse project files (inside your project)
mkdir build
cd build
cmake -G"Eclipse CDT4 - Unix Makefiles" -D CMAKE_BUILD_TYPE=Debug ..
Then import generated directory to eclipse as standard eclipse project. Right click project and open
Properties
-> C/C++ General
-> Preprocessor Include Paths, Marcos etc.
-> Providers
enable CDT GCC Build-in Compiler Settings
and move it higher than Contributed PathEntry Containers
(This is important)
Last Common Step
recompile, regenerate Project
->C/C++ Index
and restart Eclipse.
Testing this Javascript:
var arr = [1234563995.721, 12345691212.718, 1234568421.5891, 12345677093.49284];
var sum = 0;
for( var i = 0; i < arr.length; i++ ) {
sum += arr[i];
}
alert( "fMath(sum) = " + Math.round( sum * 1e12 ) / 1e12 );
alert( "fFixed(sum) = " + sum.toFixed( 5 ) );
Dont use Math.round( (## + ## + ... + ##) * 1e12) / 1e12
Instead, use ( ## + ## + ... + ##).toFixed(5) )
In IE 9, toFixed
works very well.
Mongoose will create a database if one does not already exist on connection, so once you make the connection, you can just query it to see if there is anything in it.
You can drop any database you are connected to:
var mongoose = require('mongoose');
/* Connect to the DB */
mongoose.connect('mongodb://localhost/mydatabase',function(){
/* Drop the DB */
mongoose.connection.db.dropDatabase();
});
Chrome Canary and Chromium now have WebSocket message frame inspection feature. Here are the steps to test it quickly:
Note: Every time you send or receive new messages, you have to refresh the main panel by clicking on the echo.websocket.org entry on the left.
I also posted the steps with screen shots and video.
My recently published book, The Definitive Guide to HTML5 WebSocket, also has a dedicated appendix covering the various inspection tools, including Chrome Dev Tools, Chrome net-internals, and Wire Shark.

I think you want to use typeof() here:
function f(id, parameters, callback) {
console.log(typeof(parameters)+" "+typeof(callback));
}
f("hi", {"a":"boo"}, f); //prints "object function"
f("hi", f, {"a":"boo"}); //prints "function object"
static_cast, aside from manipulating pointers to classes, can also be used to perform conversions explicitly defined in classes, as well as to perform standard conversions between fundamental types:
double d = 3.14159265;
int i = static_cast<int>(d);
You can try adb remount command also to remount /system as read write
adb remount
For me, best solution is to use Angular router native directives with ui-sref like:
<button ui-sref="state.name">Go!!</button>
To understand that directive and get more options visit ui-router docs at:
https://ui-router.github.io/docs/0.3.1/#/api/ui.router.state.directive:ui-sref

The following is the one that I'm using to generate a vertical gradient from completely opaque (top) to 20% in transparency (bottom) for the same color:

I just rechecked the performance on http://jsperf.com/javascript-concat-vs-join/2. The test-cases concatenate or join the alphabet 1,000 times.
In current browsers (FF, Opera, IE11, Chrome), "concat" is about 4-10 times faster than "join".
In IE8, both return about equal results.
In IE7, "join" is about 100 times faster unfortunately.
Also WebClient doesn't have timeout property. And that's the problem, because dafault value is 100 seconds and that's too much to indicate if there's no Internet connection.
Workaround for that problem is here https://stackoverflow.com/a/3052637/1303422
inArray returns the index of the element in the array. If the element was not found, -1 will be returned else index of element.
if(jQuery.inArray("element", myarray) === -1) {
console.log("Not exists in array");
} else {
console.log("Exists in array");
}
This will do it:
wc -c filename
If you want only the count without the filename being repeated in the output:
wc -c < filename
Edit:
Use -m
to count character instead of bytes (as shown in Sébastien's answer).
Usually this is when you have a POST form which needs to take a file upload as data... this will tell the server how it will encode the data transferred, in such case it won't get encoded because it will just transfer and upload the files to the server, Like for example when uploading an image or a pdf
Please rather try:
$JAVA_HOME/bin/java -version
Maven uses $JAVA_HOME
for classpath resolution of JRE libs.
To be sure to use a certain JDK, set it explicitly before compiling, for example:
export JAVA_HOME=/usr/java/jdk1.7.0_51
Isn't there a version < 1.7 and you're using Maven 3.3.1? In this case the reason is a new prerequisite: https://issues.apache.org/jira/browse/MNG-5780

Apple mail has also been known to make an encoding error on text and csv attachments outbound. In essence it replaces line terminators with soft line breaks on each line, which look like =0D in the encoding. If the attachment is emailed to Outlook, Outlook sees the soft line breaks, removes the = then appends real line breaks i.e. 0D0A so you get 0D0D0A (cr cr lf) at the end of each line. The encoding should be =0D= if it is a mac format file (or any other flavour of unix) or =0D0A= if it is a windows format file.
If you are emailing out from apple mail (in at least mavericks or yosemite), making the attachment not a text or csv file is an acceptable workaround e.g. compress it.
The bug also exists if you are running a windows VM under parallels and email a txt file from there using apple mail. It is the email encoding. Form previous comments here, it looks like netscape had the same issue.
Select multiple lines by clicking first line then holding shift and clicking last line. Then press:
CTRL+SHIFT+L
or on MAC: CMD+SHIFT+L (as per comments)
Alternatively you can select lines and go to SELECTION MENU >> SPLIT INTO LINES.
Now you can edit multiple lines, move cursors etc. for all selected lines.
I just release my latest library for Google Maps Direction API on Android https://github.com/akexorcist/Android-GoogleDirectionLibrary
This is possibly caused due to lost source directory.
Right click on the folder src -> Change to Source Folder
byte[] byteArray = rs.getBytes("columnname");
Bitmap bm = BitmapFactory.decodeByteArray(byteArray, 0 ,byteArray.length);
Source article: Passing a list as an argument to a vararg method
Use the toArray(T[] arr)
method.
.getMap(locations.toArray(new WorldLocation[locations.size()]))
(toArray(new WorldLocation[0])
also works, but you would allocate a zero-length array for no reason.)
Here's a complete example:
public static void method(String... strs) {
for (String s : strs)
System.out.println(s);
}
...
List<String> strs = new ArrayList<String>();
strs.add("hello");
strs.add("world");
method(strs.toArray(new String[strs.size()]));
// ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
...
bit late but here is working solution for me
var myBaseProperty = (typeof(BaseClass)).GetProperties();//get base code properties
var allProperty = entity.GetProperties()[0].DeclaringType.GetProperties();//get derived class property plus base code as it is derived from it
var declaredClassProperties = allProperty.Where(x => !myBaseProperty.Any(l => l.Name == x.Name)).ToList();//get the difference
In above mention code I am getting the properties difference between my base class and derived class list
Your stylesheet should be thought of as a static table of available variables that your html document can call on based on what you need to display. The logic should be in your javascript and html, use javascript to dynamically apply attributes based on conditions if you really need to. Stylesheets are not the place for logic.
By default, an image is rendered inline, like a letter so it sits on the same line that a, b, c and d sit on.
There is space below that line for the descenders you find on letters like g, j, p and q.

Use a custom layout for your DialogFragment
and add a LinearLayout
under your content which can be styled as borderless to match Google Material Design. Then find the newly created buttons and override their OnClickListener
.
Example:
public class AddTopicFragment extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
final View dialogView = inflater.inflate(R.layout.dialog_add_topic, null);
Button saveTopicDialogButton = (Button) dialogView.findViewById(R.id.saveTopicDialogButton);
Button cancelSaveTopicDialogButton = (Button) dialogView.findViewById(R.id.cancelSaveTopicDialogButton);
final AppCompatEditText addTopicNameET = (AppCompatEditText) dialogView.findViewById(R.id.addTopicNameET);
final AppCompatEditText addTopicCreatedByET = (AppCompatEditText) dialogView.findViewById(R.id.addTopicCreatedByET);
saveTopicDialogButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// validate inputs
if(addTopicNameET.getText().toString().trim().isEmpty()){
addTopicNameET.setError("Topic name can't be empty");
addTopicNameET.requestFocus();
}else if(addTopicCreatedByET.getText().toString().trim().isEmpty()){
addTopicCreatedByET.setError("Topic created by can't be empty");
addTopicCreatedByET.requestFocus();
}else {
// save topic to database
Topic topic = new Topic();
topic.name = addTopicNameET.getText().toString().trim();
topic.createdBy = addTopicCreatedByET.getText().toString().trim();
topic.createdDate = new Date().getTime();
topic.save();
AddTopicFragment.this.dismiss();
}
}
});
cancelSaveTopicDialogButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
AddTopicFragment.this.dismiss();
}
});
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder.setView(dialogView)
.setMessage(getString(R.string.add_topic_message));
return builder.create();
}

Create a separate ul.nav
for just that list item and float that ul
right.
Try to change where Member class

import json
with open("twitterdata.json", "w") as twitter_data_file:
json.dump(output, twitter_data_file, indent=4, sort_keys=True)
You don't need json.dumps()
if you don't want to parse the string later, just simply use json.dump()
. It's faster too.
There is no "unset" state for std::string
, it is always set to something.
I know this is a fairly old question, but I was searching for a solution to generically deserialize nested JSON to a Map<String, Object>
, and found nothing.
The way my yaml deserializer works, it defaults JSON objects to Map<String, Object>
when you don't specify a type, but gson doesn't seem to do this. Luckily you can accomplish it with a custom deserializer.
I used the following deserializer to naturally deserialize anything, defaulting JsonObject
s to Map<String, Object>
and JsonArray
s to Object[]
s, where all the children are similarly deserialized.
private static class NaturalDeserializer implements JsonDeserializer<Object> {
public Object deserialize(JsonElement json, Type typeOfT,
JsonDeserializationContext context) {
if(json.isJsonNull()) return null;
else if(json.isJsonPrimitive()) return handlePrimitive(json.getAsJsonPrimitive());
else if(json.isJsonArray()) return handleArray(json.getAsJsonArray(), context);
else return handleObject(json.getAsJsonObject(), context);
}
private Object handlePrimitive(JsonPrimitive json) {
if(json.isBoolean())
return json.getAsBoolean();
else if(json.isString())
return json.getAsString();
else {
BigDecimal bigDec = json.getAsBigDecimal();
// Find out if it is an int type
try {
bigDec.toBigIntegerExact();
try { return bigDec.intValueExact(); }
catch(ArithmeticException e) {}
return bigDec.longValue();
} catch(ArithmeticException e) {}
// Just return it as a double
return bigDec.doubleValue();
}
}
private Object handleArray(JsonArray json, JsonDeserializationContext context) {
Object[] array = new Object[json.size()];
for(int i = 0; i < array.length; i++)
array[i] = context.deserialize(json.get(i), Object.class);
return array;
}
private Object handleObject(JsonObject json, JsonDeserializationContext context) {
Map<String, Object> map = new HashMap<String, Object>();
for(Map.Entry<String, JsonElement> entry : json.entrySet())
map.put(entry.getKey(), context.deserialize(entry.getValue(), Object.class));
return map;
}
}
The messiness inside the handlePrimitive
method is for making sure you only ever get a Double or an Integer or a Long, and probably could be better, or at least simplified if you're okay with getting BigDecimals, which I believe is the default.
You can register this adapter like:
GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.registerTypeAdapter(Object.class, new NaturalDeserializer());
Gson gson = gsonBuilder.create();
And then call it like:
Object natural = gson.fromJson(source, Object.class);
I'm not sure why this is not the default behavior in gson, since it is in most other semi-structured serialization libraries...
DONT: This is not a solution!
My first approach was:
public int longToInt(long theLongOne) {
return Long.valueOf(theLongOne).intValue();
}
But that merely just casts the long to an int, potentially creating new Long
instances or retrieving them from the Long pool.
The drawbacks
Long.valueOf
creates a new Long
instance if the number is not within Long
's pool range [-128, 127].
The intValue
implementation does nothing more than:
return (int)value;
So this can be considered even worse than just casting the long
to int
.
Here is an example I used to connect node.js to my Postgres database.
The interface in node.js that I used can be found here https://github.com/brianc/node-postgres
var pg = require('pg');
var conString = "postgres://YourUserName:YourPassword@localhost:5432/YourDatabase";
var client = new pg.Client(conString);
client.connect();
//queries are queued and executed one after another once the connection becomes available
var x = 1000;
while (x > 0) {
client.query("INSERT INTO junk(name, a_number) values('Ted',12)");
client.query("INSERT INTO junk(name, a_number) values($1, $2)", ['John', x]);
x = x - 1;
}
var query = client.query("SELECT * FROM junk");
//fired after last row is emitted
query.on('row', function(row) {
console.log(row);
});
query.on('end', function() {
client.end();
});
//queries can be executed either via text/parameter values passed as individual arguments
//or by passing an options object containing text, (optional) parameter values, and (optional) query name
client.query({
name: 'insert beatle',
text: "INSERT INTO beatles(name, height, birthday) values($1, $2, $3)",
values: ['George', 70, new Date(1946, 02, 14)]
});
//subsequent queries with the same name will be executed without re-parsing the query plan by postgres
client.query({
name: 'insert beatle',
values: ['Paul', 63, new Date(1945, 04, 03)]
});
var query = client.query("SELECT * FROM beatles WHERE name = $1", ['john']);
//can stream row results back 1 at a time
query.on('row', function(row) {
console.log(row);
console.log("Beatle name: %s", row.name); //Beatle name: John
console.log("Beatle birth year: %d", row.birthday.getYear()); //dates are returned as javascript dates
console.log("Beatle height: %d' %d\"", Math.floor(row.height / 12), row.height % 12); //integers are returned as javascript ints
});
//fired after last row is emitted
query.on('end', function() {
client.end();
});
UPDATE:- THE query.on
function is now deprecated and hence the above code will not work as intended. As a solution for this look at:- query.on is not a function
You can give to_s
a base other than 10:
10.to_s(16) #=> "a"
Note that in ruby 2.4 FixNum
and BigNum
were unified in the Integer
class.
If you are using an older ruby check the documentation of FixNum#to_s
and BigNum#to_s
This works for me
var dataTable = $('#HelpdeskOverview').dataTable();
var oSettings = dataTable.fnSettings();
dataTable.fnClearTable(this);
for (var i=0; i<json.aaData.length; i++)
{
dataTable.oApi._fnAddData(oSettings, json.aaData[i]);
}
oSettings.aiDisplay = oSettings.aiDisplayMaster.slice();
dataTable.fnDraw();
The application will appear in your projects Build directory. In the source pane on the left of the Xcode window you should see a section called 'Products'. Listed under there will be your application name. If you right-click on this you can select 'Reveal in Finder' to be taken to the application in the Finder. You can send this to your friend directly and he can just copy it into his Applications folder. Most applications do not require an installer package on Mac OS X.
Although Git has an internal implementation of diff, you can set up an external tool instead.
There are two different ways to specify an external diff tool:
GIT_EXTERNAL_DIFF
and the GIT_DIFF_OPTS
environment variables.git config
See also:
git diff --help
When doing a git diff
, Git checks both the settings of above environment variables and its .gitconfig
file.
By default, Git passes the following seven arguments to the diff program:
path old-file old-hex old-mode new-file new-hex new-mode
You typically only need the old-file and new-file parameters. Of course most diff tools only take two file names as an argument. This means that you need to write a small wrapper-script, which takes the arguments which Git provides to the script, and hands them on to the external git program of your choice.
Let's say you put your wrapper-script under ~/scripts/my_diff.sh
:
#!/bin/bash
# un-comment one diff tool you'd like to use
# side-by-side diff with custom options:
# /usr/bin/sdiff -w200 -l "$2" "$5"
# using kdiff3 as the side-by-side diff:
# /usr/bin/kdiff3 "$2" "$5"
# using Meld
/usr/bin/meld "$2" "$5"
# using VIM
# /usr/bin/vim -d "$2" "$5"
you then need to make that script executable:
chmod a+x ~/scripts/my_diff.sh
you then need to tell Git how and where to find your custom diff wrapper script. You have three choices how to do that: (I prefer editing the .gitconfig file)
Using GIT_EXTERNAL_DIFF
, GIT_DIFF_OPTS
e.g. in your .bashrc or .bash_profile file you can set:
GIT_EXTERNAL_DIFF=$HOME/scripts/my_diff.sh
export GIT_EXTERNAL_DIFF
Using git config
use "git config" to define where your wrapper script can be found:
git config --global diff.external ~/scripts/my_diff.sh
Editing your ~/.gitconfig
file
you can edit your ~/.gitconfig
file to add these lines:
[diff]
external = ~/scripts/my_diff.sh
Note:
Similarly to installing your custom diff tool, you can also install a custom merge-tool, which could be a visual merging tool to better help visualizing the merge. (see the progit.org page)
See: http://fredpalma.com/518/visual-diff-and-merge-tool/ and https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration
HttpClient is a new API that came with 4.3, it has updated API's with support for progress events, json deserialization by default, Interceptors and many other great features. See more here https://angular.io/guide/http
Http is the older API and will eventually be deprecated.
Since their usage is very similar for basic tasks I would advise using HttpClient since it is the more modern and easy to use alternative.
I recommend mongoskin I just created.
var mongo = require('mongoskin');
var db = mongo.db('admin:pass@localhost/mydb?auto_reconnnect');
db.collection('mycollection').find().toArray(function(err, items){
// do something with items
});
Is mongoskin sync? Nop, it is async.
You could do this:
db.copyDatabase("db_to_rename","db_renamed","localhost")
use db_to_rename
db.dropDatabase();
Editorial Note: this is the same approach used in the question itself but has proven useful to others regardless.

Search for services.msc and look up through your services that are running if there is a mysql service running already other than the one you want to run (it could be xampp or wamp) or another service (for example Skype) using the same port as mysql and stop the service so you can run your mysql service.
As Alex hinted in one of the answers, you could use the ContentNegotiationManagerFactoryBean to set the default content-type to "application/json", but I felt that that approach was not for me.
What I was trying to do was to post a form to a method like this
@RequestMapping(value = "/post/to/me", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public @ResponseBody MyJsonPOJO handlePostForm(@Valid @ModelAttribute("form") ValidateMeForm form, BindingResult bindingResult) throws ApiException {
What I instead chose to do was to change the "Accept" header of the request from the browser to "application/json", thereby making SpringMVC find my method.
Using the (not yet finalized) Javascript Fetch API:
var form = new FormData();
form.append("myData", "data");
let fetchConfig = {
method: "POST",
body: form,
headers: {"Accept": "application/json"}
};
fetch("/post/to/me", fetchConfig)
.then(... // Javascript Promise API here
Et voilà! Now SpringMVC finds the method, validates the form, and lets you return a JSON POJO.
Since there were no exact answers to my question, I made some investigation why my code doesn't work when there are other solutions that works, and decided to post what I found to complete the subject.
As it turns out:
"ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user." sshpass manpage
which answers the question, why the pipes don't work in this case. The obvious solution was to create conditions so that ssh
"thought" that it is run in the regular terminal and since it may be accomplished by simple posix
functions, it is beyond what simple bash
offers.
Instead of directly saving the private key Go to Conversions and Export SSh Key. Had the same issue and this worked for me
if you post a file from mobile device or other
byte[] fileData = null;
using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
{
fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
}
Check out this snippet:
Private Sub openDialog()
Dim fd As Office.FileDialog
Set fd = Application.FileDialog(msoFileDialogFilePicker)
With fd
.AllowMultiSelect = False
' Set the title of the dialog box.
.Title = "Please select the file."
' Clear out the current filters, and add our own.
.Filters.Clear
.Filters.Add "Excel 2003", "*.xls"
.Filters.Add "All Files", "*.*"
' Show the dialog box. If the .Show method returns True, the
' user picked at least one file. If the .Show method returns
' False, the user clicked Cancel.
If .Show = True Then
txtFileName = .SelectedItems(1) 'replace txtFileName with your textbox
End If
End With
End Sub
I think this is what you are asking for.
You could upload via $resource
by assigning data to params attribute of resource actions
like so:
$scope.uploadFile = function(files) {
var fdata = new FormData();
fdata.append("file", files[0]);
$resource('api/post/:id', { id: "@id" }, {
postWithFile: {
method: "POST",
data: fdata,
transformRequest: angular.identity,
headers: { 'Content-Type': undefined }
}
}).postWithFile(fdata).$promise.then(function(response){
//successful
},function(error){
//error
});
};
Use numpy.append
:
>>> a = np.array([[1,2,3],[2,3,4]])
>>> a
array([[1, 2, 3],
[2, 3, 4]])
>>> z = np.zeros((2,1), dtype=int64)
>>> z
array([[0],
[0]])
>>> np.append(a, z, axis=1)
array([[1, 2, 3, 0],
[2, 3, 4, 0]])
It will have already gone back before it executes the reload.
You would be better off to replace:
window.history.back();
location.reload();
with:
window.location.replace("pagehere.html");
Sometimes this is enough, the first argument will always be the file path

"You must specify a region" is a not an ECS specific error, it can happen with any AWS API/CLI/SDK command.
For the CLI, either set the AWS_DEFAULT_REGION
environment variable. e.g.
export AWS_DEFAULT_REGION=us-east-1
or add it into the command (you will need this every time you use a region-specific command)
AWS_DEFAULT_REGION=us-east-1 aws ecs list-container-instances --cluster default
or set it in the CLI configuration file: ~/.aws/config
[default]
region=us-east-1
or pass/override it with the CLI call:
aws ecs list-container-instances --cluster default --region us-east-1

@JsonFormat only work for standard format supported by the jackson version that you are using.
Ex :- compatible with any of standard forms ("yyyy-MM-dd'T'HH:mm:ss.SSSZ", "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "EEE, dd MMM yyyy HH:mm:ss zzz", "yyyy-MM-dd")) for jackson 2.8.6

Ramil Amr's answer works only for the & character. If you have some other special characters, you should use PHP's htmlspecialchars()
and JS's encodeURIComponent()
.
You can write:
var wysiwyg_clean = encodeURIComponent(wysiwyg);
And on the server side:
htmlspecialchars($_POST['wysiwyg']);
This will make sure that AJAX will pass the data as expected, and that PHP (in case your'e insreting the data to a database) will make sure the data works as expected.
CSS3 offers a way to do it with the @font-face rule.
http://www.w3.org/TR/css3-webfonts/#the-font-face-rule

Here is a number of different ways which will work in browsers that don't support the @font-face rule.
It should be while(true)
not while(1)
, so while(1)
is incorrect in C#, yes ;)
you can try this.

Hint: Ctrl + Space in the textboxes gives you all kinds of suggestions for regular expression writing.
As mentioned before, you can manually edit your project's .csproj
file in order to apply it manually.
I also noticed that Visual Studio 2013 attempts to apply a relative path to the reference hintpath, probably because of an attempt to make the project file more portable.

First, you split the data using split
:
split(z,z$Group)
Than, for each chunk, select the row with max Score:
lapply(split(z,z$Group),function(chunk) chunk[which.max(chunk$Score),])
Finally reduce back to a data.frame do.call
ing rbind
:
do.call(rbind,lapply(split(z,z$Group),function(chunk) chunk[which.max(chunk$Score),]))
Result:
Group Score Info
1 1 3 c
2 2 4 d

Python is only a language, to get GET and POST data, you need a web framework or toolkit written in Python. Django is one, as Charlie points out, the cgi and urllib standard modules are others. Also available are Turbogears, Pylons, CherryPy, web.py, mod_python, fastcgi, etc, etc.
In Django, your view functions receive a request argument which has request.GET and request.POST. Other frameworks will do it differently.
Under NT-style cmd.exe, you can loop through the lines of a text file with
FOR /F %i IN (file.txt) DO @echo %i
Type "help for" on the command prompt for more information. (don't know if that works in whatever "DOS" you are using)
Just thought I would expand on this a bit.
If you perform a MYSQLI SELECT query that returns 0 results, it returns FALSE.
However, if you get this error and you have written your own MYSQLI Query function, then you can also get this error if the query you are running is not a select but an update. An update query will return either TRUE or FALSE. So if you just assume that any non false result will have records returned, then you will trip up when you run an update or anything other than select.
The easiest solution, once you have checked that its not false, is to first check that the result of the query is an object.
$sqlResult = $connection->query($sql);
if (!$sqlResult)
{
...
}
else if (is_object($sqlResult))
{
$sqlRowCount = $sqlResult->num_rows;
}
else
{
$sqlRowCount = 0;
}
Maybe this will help someone else, but I've seen this error when the RHS of the mapping contains a colon without enclosing quotes, such as:
someKey: another key: Change to make today: work out more
should be
someKey: another key: "Change to make today: work out more"
Right click on the .cs
file in the App_Code
folder and check its properties.
Make sure the "Build Action" is set to "Compile".
Plain JavaScript:
document.getElementById('form_id').action; //Will retrieve it
document.getElementById('form_id').action = "script.php"; //Will set it
Using jQuery...
$("#form_id").attr("action"); //Will retrieve it
$("#form_id").attr("action", "/script.php"); //Will set it
Pycharm shortcut for running "Selection" in the console is ALT + SHIFT + e
For this to work properly, you'll have to run everything this way.
For anyone who likes 1-liners and a single regex, but doesn't want to use split(), here is an enhanced version of the regex from other answers that handles (ignores) decimal places:
var formatted = (x+'').replace(/(\..*)$|(\d)(?=(\d{3})+(?!\d))/g, (digit, fract) => fract || digit + ',');
The regex first matches a substring starting with a literal "." and replaces it with itself ("fract"), and then matches any digit followed by multiples of 3 digits and puts "," after it.
For example, x = 12345678.12345678 will give formatted = '12,345,678.12345678'.
I was looking for the same and ended up by creating a static method inside a Helper class (in my case I named it App\Helpers\Database).
The method
/**
* Method to get the autoincrement value from a database table
*
* @access public
*
* @param string $database The database name or configuration in the .env file
* @param string $table The table name
*
* @return mixed
*/
public static function getAutoIncrementValue($database, $table)
{
$database ?? env('DB_DATABASE');
return \DB::select("
SELECT AUTO_INCREMENT
FROM information_schema.TABLES
WHERE TABLE_SCHEMA = '" . env('DB_DATABASE') . "'
AND TABLE_NAME = '" . $table . "'"
)[0]->AUTO_INCREMENT;
}
To call the method and get the MySql AUTO_INCREMENT just use the following:
$auto_increment = \App\Helpers\Database::getAutoIncrementValue(env('DB_DATABASE'), 'your_table_name');
Hope it helps.

Notice : in case when you just need to change some specific collation use condition like this :
WHERE c.object_id = OBJECT_ID(@table) AND (t.Name LIKE '%char%' OR t.Name LIKE '%text%')
AND c.collation_name = 'collation to change'
e.g. NOT the : AND c.collation_name <> @collate
In my case, I had correct / specified collation of some columns and didn't want to change them.
You can also use CircleAvatar
, which comes with flutter
CircleAvatar(
radius: 20,
backgroundImage: NetworkImage('https://via.placeholder.com/140x100')
)
add the following to you preamble:
\newcommand{\newCommandName}{text to insert}
Then you can just use \newCommandName{}
in the text
For more info on \newcommand
, see e.g. wikibooks
Example:
\documentclass{article}
\newcommand\x{30}
\begin{document}
\x
\end{document}
Output:

For Rails4:
So, what you're wanting is an inner join, so you really should just use the joins predicate:
Foo.joins(:bar)
Select * from Foo Inner Join Bars ...
But, for the record, if you want a "NOT NULL" condition simply use the not predicate:
Foo.includes(:bar).where.not(bars: {id: nil})
Select * from Foo Left Outer Join Bars on .. WHERE bars.id IS NOT NULL
Note that this syntax reports a deprecation (it talks about a string SQL snippet, but I guess the hash condition is changed to string in the parser?), so be sure to add the references to the end:
Foo.includes(:bar).where.not(bars: {id: nil}).references(:bar)
DEPRECATION WARNING: It looks like you are eager loading table(s) (one of: ....) that are referenced in a string SQL snippet. For example:
Post.includes(:comments).where("comments.title = 'foo'")
Currently, Active Record recognizes the table in the string, and knows to JOIN the comments table to the query, rather than loading comments in a separate query. However, doing this without writing a full-blown SQL parser is inherently flawed. Since we don't want to write an SQL parser, we are removing this functionality. From now on, you must explicitly tell Active Record when you are referencing a table from a string:
Post.includes(:comments).where("comments.title = 'foo'").references(:comments)
PreparedStatements are the way to go, because they make SQL injection impossible. Here's a simple example taking the user's input as the parameters:
public insertUser(String name, String email) {
Connection conn = null;
PreparedStatement stmt = null;
try {
conn = setupTheDatabaseConnectionSomehow();
stmt = conn.prepareStatement("INSERT INTO person (name, email) values (?, ?)");
stmt.setString(1, name);
stmt.setString(2, email);
stmt.executeUpdate();
}
finally {
try {
if (stmt != null) { stmt.close(); }
}
catch (Exception e) {
// log this error
}
try {
if (conn != null) { conn.close(); }
}
catch (Exception e) {
// log this error
}
}
}
No matter what characters are in name and email, those characters will be placed directly in the database. They won't affect the INSERT statement in any way.
There are different set methods for different data types -- which one you use depends on what your database fields are. For example, if you have an INTEGER column in the database, you should use a setInt
method. The PreparedStatement documentation lists all the different methods available for setting and getting data.
I had the same problem but solved it running following:
$ adb shell
$ run-as {app-package-name}
$ cd /data/data/{app-package-name}
$ chmod 777 {file}
$ cp {file} /mnt/sdcard/
After this you can run
$ adb pull /mnt/sdcard/{file}

AFAIK, fragments cannot hold other fragments.
UPDATE
With current versions of the Android Support package -- or native fragments on API Level 17 and higher -- you can nest fragments, by means of getChildFragmentManager()
. Note that this means that you need to use the Android Support package version of fragments on API Levels 11-16, because even though there is a native version of fragments on those devices, that version does not have getChildFragmentManager()

XML is not a format for storing images, neither binary data. I think it all depends on how you want to use those images. If you are in a web application and would want to read them from there and display them, I would store the URLs. If you need to send them to another web endpoint, I would serialize them, rather than persisting manually in XML. Please explain what is the scenario.

Create a reverse dictionary using the calendar
module (which, like any module, you will need to import):
{month: index for index, month in enumerate(calendar.month_abbr) if month}
In Python versions before 2.7, due to dict comprehension syntax not being supported in the language, you would have to do
dict((month, index) for index, month in enumerate(calendar.month_abbr) if month)

return (Math.random() * (max + 1 - min)) + min;

In case you want to test you app on your physical device via WiFi:

4.) Type in your Android Studio terminal: adb connect <ip address of your device>
Alternatively, you can use WiFi ADB extension for Android Studio. I don't know any similar extension for VS Code.

will not work, you must pass it as an array: subprocess.call(["sleep.sh", 10])

I do need to mention that @Thomas Haratyk simply inquired why I didn't simply use echo
.
At the time, I didn't know about echo, as I'm learning shell-scripting
, but he was right.
My simple solution is now this:
#!/bin/bash
echo "This logs to where I want, but using echo" > /var/log/mycustomlog
The example above will overwrite the file after the >
So, I can append to that file with this:
#!/bin/bash
echo "I will just append to my custom log file" >> /var/log/customlog
Thanks guys!
/var/log/
, but I'm sure there are other good ideas out there. And since I didn't create a daemon, /var/log/
probably isn't the best place for my custom log file. (just saying)Specifically, I want to mention one situation, by which you may confuse.
What is the difference between "\0" and ""?
The answer is that "\0"
represents in array is {0 0}
and ""
is {0}
.
Because "\0"
is still a string literal and it will also add "\0"
at the end of it. And ""
is empty but also add "\0"
.
Understanding of this will help you understand "\0"
deeply.
To remove an entire folder from the repo (like Resharper files), do this:
git rm -r --cached folderName
I had committed some resharper files, and did not want those to persist for other project users.
I looked into the options pattern sample and saw this:
public class Startup
{
public Startup(IConfiguration config)
{
// Configuration from appsettings.json has already been loaded by
// CreateDefaultBuilder on WebHost in Program.cs. Use DI to load
// the configuration into the Configuration property.
Configuration = config;
}
...
}
When adding Iconfiguration in the constructor of my class, I could access the configuration options through DI.
Example:
public class MyClass{
private Iconfiguration _config;
public MyClass(Iconfiguration config){
_config = config;
}
... // access _config["myAppSetting"] anywhere in this class
}

The SAMPLE clause will give you a random sample percentage of all rows in a table.
For example, here we obtain 25% of the rows:
SELECT * FROM emp SAMPLE(25)
The following SQL (using one of the analytical functions) will give you a random sample of a specific number of each occurrence of a particular value (similar to a GROUP BY) in a table.
Here we sample 10 of each:
SELECT * FROM (
SELECT job, sal, ROW_NUMBER()
OVER (
PARTITION BY job ORDER BY job
) SampleCount FROM emp
)
WHERE SampleCount <= 10
Maybe bind() would help:
button.bind('click', function() {
alert('User clicked');
});

Start with a subset of the original data:

1318748400, 1318834800, 1318921200, 1319007600, 1319094000), class = c("POSIXct",
"POSIXt"), tzone = ""), TempMax = c(26.58, 27.78, 27.9, 27.44,
30.9, 30.44, 27.57, 25.71, 25.98, 26.84, 33.58, 30.7, 31.3, 27.18,
26.58, 26.18, 25.19, 24.19, 27.65, 23.92), TempMedia = c(22.88,
22.87, 22.41, 21.63, 22.43, 22.29, 21.89, 20.52, 19.71, 20.73,
23.51, 23.13, 22.95, 21.95, 21.91, 20.72, 20.45, 19.42, 19.97,
19.61), TempMin = c(19.34, 19.14, 18.34, 17.49, 16.75, 16.75,
16.88, 16.82, 14.82, 16.01, 16.88, 17.55, 16.75, 17.22, 19.01,

geom_line(aes(y = TempMax, colour = "TempMax")) +
geom_line(aes(y = TempMedia, colour = "TempMedia")) +

The idea is that each line is given a color by mapping the colour
aesthetic to a constant string. Choosing the string which is what you want to appear in the legend is the easiest. The fact that in this case it is the same as the name of the y
variable being plotted is not significant; it could be any set of strings. It is very important that this is inside the aes
call; you are creating a mapping to this "variable".
scale_colour_manual
can now map these strings to the appropriate colors. The result is
In some cases, the mapping between the levels and colors needs to be made explicit by naming the values in the manual scale (thanks to @DaveRGP for pointing this out):
ggplot(data = datos, aes(x = fecha)) +
geom_line(aes(y = TempMax, colour = "TempMax")) +
geom_line(aes(y = TempMedia, colour = "TempMedia")) +
geom_line(aes(y = TempMin, colour = "TempMin")) +
scale_colour_manual("",
values = c("TempMedia"="green", "TempMax"="red",
"TempMin"="blue")) +
xlab(" ") +
scale_y_continuous("Temperatura (C)", limits = c(-10,40)) +
labs(title="TITULO")
(giving the same figure as before). With named values, the breaks can be used to set the order in the legend and any order can be used in the values.
ggplot(data = datos, aes(x = fecha)) +
geom_line(aes(y = TempMax, colour = "TempMax")) +
geom_line(aes(y = TempMedia, colour = "TempMedia")) +

Changing XAMPP Default Port: If you want to get XAMPP up and running, you should consider changing the port from the default 80 to say 7777.
In the XAMPP Control Panel, click on the Apache – Config button which is located next to the ‘Logs’ button.
Select ‘Apache (httpd.conf)’ from the drop down. (Notepad should open)
Do Ctrl+F to find ’80’ and change line Listen 80 to Listen 7777
Find again and change line ServerName localhost:80 to ServerName localhost:7777
Save and re-start Apache. It should be running by now.
The only demerit to this technique is, you have to explicitly include the port number in the localhost url. Rather than http://localhost
it becomes http://localhost:7777
.
First thing we've tried was to disable dynamic content compression for IIS , that solved the errors but the error wasn't caused server side and only one client was affected by this.
On client side we uninstalled VPN clients, reset internet settings and then reinstalled VPN clients. The error could also be caused by previous antivirus which had firewall. Then we enabled back dynamic content compression and now it works fine as before.
Error appeared in custom application which connects to a web service and also at TFS.

the window
contains everything, so you can call window.screen
and window.document
to get those elements. Check out this fiddle, pretty-printing the contents of each object: http://jsfiddle.net/JKirchartz/82rZu/
You can also see the contents of the object in firebug/dev tools like this:
console.dir(window);
console.dir(document);
console.dir(screen);
window
is the root of everything, screen
just has screen dimensions, and document
is top DOM object. so you can think of it as window
being like a super-document

Alexis has already posted an answer in Java 8 using method toMap(keyMapper, valueMapper)
. As per doc for this method implementation:
There are no guarantees on the type, mutability, serializability, or thread-safety of the Map returned.
So in case we are interested in a specific implementation of Map
interface e.g. HashMap
then we can use the overloaded form as:
Map<String, Item> map2 =
itemList.stream().collect(Collectors.toMap(Item::getKey, //key for map
Function.identity(), // value for map
(o,n) -> o, // merge function in case of conflict with keys
HashMap::new)); // map factory - we want HashMap and not any Map implementation
Though using either Function.identity()
or i->i
is fine but it seems Function.identity()
instead of i -> i
might save some memory as per this related answer.
I had this same error. Just had to install IIS and everything worked.
The StartsWith method will be faster, as there is no overhead of interpreting a regular expression, but here is how you do it:
if (Regex.IsMatch(theString, "^(mailto|ftp|joe):")) ...
The ^
mathes the start of the string. You can put any protocols between the parentheses separated by |
characters.
Another approach that is much faster, is to get the start of the string and use in a switch. The switch sets up a hash table with the strings, so it's faster than comparing all the strings:
int index = theString.IndexOf(':');
if (index != -1) {
switch (theString.Substring(0, index)) {
case "mailto":
case "ftp":
case "joe":
// do something
break;
}
}
Depending on distribution, using "cron reload" might do nothing. To paste a snippet out of init.d/cron (debian squeeze):
reload|force-reload) log_daemon_msg "Reloading configuration files for periodic command scheduler" "cron"
# cron reloads automatically
log_end_msg 0
;;
Some developer/maintainer relied on it reloading, but doesn't, and in this case there's not a way to force reload. I'm generating my crontab files as part of a deploy, and unless somehow the length of the file changes, the changes are not reloaded.
In vanilla JavaScript, this will give you the AVAILABLE width/height:
window.screen.availHeight
window.screen.availWidth
For the absolute width/height, use:
window.screen.height
window.screen.width
Both of the above can be written without the window prefix.
Like jQuery? This works in all browsers, but each browser gives different values.
$(window).width()
$(window).height()
This msdn article explains it very well with examples, "A tuple is a data structure that has a specific number and sequence of elements".
Tuples are commonly used in four ways:
To represent a single set of data. For example, a tuple can represent a database record, and its components can represent individual fields of the record.
To provide easy access to, and manipulation of, a data set.
To return multiple values from a method without using out parameters (in C#) or
ByRef
parameters (in Visual Basic).To pass multiple values to a method through a single parameter. For example, the
Thread.Start(Object)
method has a single parameter that lets you supply one value to the method that the thread executes at startup time. If you supply aTuple<T1, T2, T3>
object as the method argument, you can supply the thread’s startup routine with three items of data.
The GMaps Utility Library has a plugin called MapIconMaker that makes it easy to generate different marker styles on the fly. It uses Google Charts to draw the markers.
There's a good demo here that shows what kind of markers you can make with it.
The Angular microsyntax lets you configure a directive in a compact, friendly string. The microsyntax parser translates that string into attributes on the <ng-template>
. The let keyword declares a template input variable that you reference within the template.
This is a fun solution with SQL Server 2005 that I like. I'm going to assume that by "for every record except for the first one", you mean that there is another "id" column that we can use to identify which row is "first".
SELECT id
, field1
, field2
, field3
FROM
(
SELECT id
, field1
, field2
, field3
, RANK() OVER (PARTITION BY field1, field2, field3 ORDER BY id ASC) AS [rank]
FROM table_name
) a
WHERE [rank] > 1
new String(byteArray, Charset.defaultCharset())
This will convert a byte array to the default charset in java. It may throw exceptions depending on what you supply with the byteArray.
If you're running ubuntu container directly without a local Dockerfile you can ssh into the container and enable root control by entering su

I use templates for long text:
email-template.txt contains
hello {name}!
how are you?
In PHP I do this:
$email = file_get_contents('email-template.txt');
$email = str_replace('{name},', 'Simon', $email);

First, I think you're calling it the wrong thing. "JSON" stands for "JavaScript Object Notation" - it's just a specification for representing some data in a string that explicitly mimics JavaScript object (and array, string, number and boolean) literals. You're trying to build up a JavaScript object dynamically - so the word you're looking for is "object".
With that pedantry out of the way, I think that you're asking how to set object and array properties.
// make an empty object
var myObject = {};
// set the "list1" property to an array of strings
myObject.list1 = ['1', '2'];
// you can also access properties by string
myObject['list2'] = [];
// accessing arrays is the same, but the keys are numbers
myObject.list2[0] = 'a';
myObject['list2'][1] = 'b';
myObject.list3 = [];
// instead of placing properties at specific indices, you
// can push them on to the end
myObject.list3.push({});
// or unshift them on to the beginning
myObject.list3.unshift({});
myObject.list3[0]['key1'] = 'value1';
myObject.list3[1]['key2'] = 'value2';
myObject.not_a_list = '11';
That code will build up the object that you specified in your question (except that I call it myObject instead of myJSON). For more information on accessing properties, I recommend the Mozilla JavaScript Guide and the book JavaScript: The Good Parts.

jnz loopstart ;much faster on Intel (and possibly AMD as I haven't

I use when I do a big commit, above all when I remove more files from the repository.. after, the commits are faster
DateTime unixEpoch = DateTime.ParseExact("1970-01-01", "yyyy-MM-dd", System.Globalization.CultureInfo.InvariantCulture);
DateTime convertedTime = unixEpoch.AddMilliseconds(unixTimeInMillisconds);
Of course, one can make unixEpoch
a global static, so it only needs to appear once in your project, and one can use AddSeconds
if the UNIX time is in seconds.
To go the other way:
double unixTimeInMilliseconds = timeToConvert.Subtract(unixEpoch).TotalMilliseconds;
Truncate to Int64 and/or use TotalSeconds
as needed.

I know this is an old question but here is something to try: Make your multidimensional array, and place it inside an html tag. This way you can precisely aim your array'd input:
//Your Holding tag for your inputs!
<div id='input-container' class='funky'></div>
<script>
//With VAR: you can seperate each variable with a comma instead of:
//creating var at the beginning and a semicolon at the end.
//Creates a cleaner layout of your variables
var
arr=[['input1-1','input1-2'],['input2-1','input2-2']],
//globall calls these letters var so you dont have to recreate variable below
i,j
;
//Instead of the general 'i<array.length' you can go even further
//by creating array[i] in place of 'i<array.length'
for(i=0;arr[i];i++){
for(j=0;arr[i][j];j++){
document.getElementById('input-container').innerHTML+=
"<input class='inner-funky'>"+arr[i][j]+"</input>"
;
}}
</script>
Its simply a neater way to write your code and easier to invoke. You can check my demo here!
Install these packages:
Code:
static void Main(string[] args)
{
var environmentName = Environment.GetEnvironmentVariable("ENVIRONMENT");
Console.WriteLine("ENVIRONMENT: " + environmentName);
var builder = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", false)
.AddJsonFile($"appsettings.{environmentName}.json", true)
.AddEnvironmentVariables();
IConfigurationRoot configuration = builder.Build();
var mySettingsConfig = configuration.Get<MySettingsConfig>();
Console.WriteLine("URL: " + mySettingsConfig.Url);
Console.WriteLine("NAME: " + mySettingsConfig.Name);
Console.ReadKey();
}
MySettingsConfig Class:
public class MySettingsConfig
{
public string Url { get; set; }
public string Name { get; set; }
}
This is what I did:
$ wget http://sourceforge.net/projects/mcrypt/files/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz/download
$ tar xzvf libmcrypt-2.5.8.tar.gz
$ ./configure
$ make
$ sudo make install
$ brew install autoconf
$ wget file:///Users/rmatikolai/Downloads/php-5.4.24.tar.bz2
$ tar xjvf php-5.4.24.tar.bz2
$ cd php-5.4.24/ext/mcrypt
$ phpize
$ ./configure # this is the step which fails without the above dependencies
$ make
$ make test
$ sudo make install
$ sudo cp /private/etc/php.ini.default /private/etc/php.ini
$ sudo vi /private/etc/php.ini
Next, you need to add the line:
extension=mcrypt.so
$ sudo apachectl restart
First off, Xvfb doesn't read configuration from xorg.conf. Xvfb is a variant of the KDrive X servers and like all members of that family gets its configuration from the command line.
It is true that XRandR and Xinerama are mutually exclusive, but in the case of Xvfb there's no Xinerama in the first place. You can enable the XRandR extension by starting Xvfb using at least the following command line options
Xvfb +extension RANDR [further options]
It is very simple, just add a property:
public string Value {
get { return textBox1.Text; }
set { textBox1.Text = value; }
}
Using the Text property is a bit trickier, the UserControl class intentionally hides it. You'll need to override the attributes to put it back in working order:
[Browsable(true), EditorBrowsable(EditorBrowsableState.Always), Bindable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public override string Text {
get { return textBox1.Text; }
set { textBox1.Text = value; }
}
