There are ports of flex and bison for windows here: http://gnuwin32.sourceforge.net/

flex is the free implementation of lex. bison is the free implementation of yacc.

Somewhere in your code there is a line #include <string>. This by itself tells you that the program is written in C++. So using g++ is better than gcc.

For the missing library: you should look around in the file system if you can find a file called libl.so. Use the locate command, try /usr/lib, /usr/local/lib, /opt/flex/lib, or use the brute-force find / | grep /libl.

Once you have found the file, you have to add the directory to the compiler command line, for example:

g++ -o scan lex.yy.c -L/opt/flex/lib -ll

Use the synaptic packet manager in order to install yacc / lex. If you are feeling more comfortable doing this on the console just do:

sudo apt-get install bison flex

There are some very nice articles on the net on how to get started with those tools. I found the article from CodeProject to be quite good and helpful (see here). But you should just try and search for "introduction to lex", there are plenty of good articles showing up.

An asynchronously loaded script is likely going to run AFTER the document has been fully parsed and closed. Thus, you can't use document.write() from such a script (well technically you can, but it won't do what you want).

You will need to replace any document.write() statements in that script with explicit DOM manipulations by creating the DOM elements and then inserting them into a particular parent with .appendChild() or .insertBefore() or setting .innerHTML or some mechanism for direct DOM manipulation like that.

For example, instead of this type of code in an inline script:

<div id="container">
<script>
document.write('<span style="color:red;">Hello</span>');
</script>
</div>

You would use this to replace the inline script above in a dynamically loaded script:

var container = document.getElementById("container");
var content = document.createElement("span");
content.style.color = "red";
content.innerHTML = "Hello";
container.appendChild(content);

Or, if there was no other content in the container that you needed to just append to, you could simply do this:

var container = document.getElementById("container");
container.innerHTML = '<span style="color:red;">Hello</span>';

Firstly add a div with id.

<div id="my_map_add" style="width:100%;height:300px;"></div>

<script type="text/javascript">
function my_map_add() {
var myMapCenter = new google.maps.LatLng(28.5383866, 77.34916609);
var myMapProp = {center:myMapCenter, zoom:12, scrollwheel:false, draggable:false, mapTypeId:google.maps.MapTypeId.ROADMAP};
var map = new google.maps.Map(document.getElementById("my_map_add"),myMapProp);
var marker = new google.maps.Marker({position:myMapCenter});
marker.setMap(map);
}
</script>

<script src="https://maps.googleapis.com/maps/api/js?key=your_key&callback=my_map_add"></script>

Check out Google Collections' Multimap, e.g. page 28 of this presentation.

If you can't use that library for some reason, consider using ConcurrentHashMap instead of SynchronizedHashMap; it has a nifty putIfAbsent(K,V) method with which you can atomically add the element list if it's not already there. Also, consider using CopyOnWriteArrayList for the map values if your usage patterns warrant doing so.

First you need to check which version of git you are running, the one installed with brew should be running on /usr/local/bin/git , you can verify this from a terminal using:

which git

In case git shows up on a different directory you need to run this from a terminal to add it to your path:

echo export PATH='/usr/local/bin:$PATH' >> ~/.bash_profile

After that you can close and open again your terminal or just run:

source ~/.bash_profile

And voila! In case you are running on OSX Mavericks you might need to install XQuartz.

The underlying MD5 algorithm is no longer deemed secure, thus while md5sum is well-suited for identifying known files in situations that are not security related, it should not be relied on if there is a chance that files have been purposefully and maliciously tampered. In the latter case, the use of a newer hashing tool such as sha256sum is highly recommended.

So, if you are simply looking to check for file corruption or file differences, when the source of the file is trusted, MD5 should be sufficient. If you are looking to verify the integrity of a file coming from an untrusted source, or over from a trusted source over an unencrypted connection, MD5 is not sufficient.

Another commenter noted that Ubuntu and others use MD5 checksums. Ubuntu has moved to PGP and SHA256, in addition to MD5, but the documentation of the stronger verification strategies are more difficult to find. See the HowToSHA256SUM page for more details.

First you need to keep copy of following somewhere in your hard disk.

C:\xampp\mysql\backup

C:\xampp\mysql\data

After that

Copy every thing inside "C:\xampp\mysql\backup" and paste and replace it in
"C:\xampp\mysql\data"

Now your mysql will work in phpmyadmin but your tables will show "Table not found in engine"

For this you will have to go to the copy of "backup and data folders" which have created in your hard disk and there in the data folder copy "ibdata1" file and past and replace in the "C:\xampp\mysql\data".

Now your tables data will be available.

I personally prefer using the following code if it is for a single link. Otherwise it's probably best if you create a function with similar code.

onclick="this.target='_blank';"

I started using that to bypass the W3C's XHTML strict test.

Are you putting this line inside the class declaration? In that case you should remove the JSONDeserializer::.

if number >= 10000 and number <= 30000:

As mentioned earlier, you can use the grid system to layout your inputs and labels anyway that you want. The trick is to remember that you can use rows within your columns to break them into twelfths as well.

The example below is one possible way to accomplish your goal and will put the two text boxes near Label3 on the same line when the screen is small or larger.

What can you do about it?

There is a lot of good answers here explaining what a null reference is and how to debug it. But there is very little on how to prevent the issue or at least make it easier to catch.

Check arguments

For example, methods can check the different arguments to see if they are null and throw an ArgumentNullException, an exception obviously created for this exact purpose.

The constructor for the ArgumentNullException even takes the name of the parameter and a message as arguments so you can tell the developer exactly what the problem is.

public void DoSomething(MyObject obj) {
    if(obj == null) 
    {
        throw new ArgumentNullException("obj", "Need a reference to obj.");
    }
}

Use Tools

There are also several libraries that can help. "Resharper" for example can provide you with warnings while you are writing code, especially if you use their attribute: NotNullAttribute

There's "Microsoft Code Contracts" where you use syntax like Contract.Requires(obj != null) which gives you runtime and compile checking: Introducing Code Contracts.

There's also "PostSharp" which will allow you to just use attributes like this:

public void DoSometing([NotNull] obj)

By doing that and making PostSharp part of your build process obj will be checked for null at runtime. See: PostSharp null check

Plain Code Solution

Or you can always code your own approach using plain old code. For example here is a struct that you can use to catch null references. It's modeled after the same concept as Nullable<T>:

[System.Diagnostics.DebuggerNonUserCode]
public struct NotNull<T> where T: class
{
    private T _value;

    public T Value
    {
        get
        {
            if (_value == null)
            {
                throw new Exception("null value not allowed");
            }

            return _value;
        }
        set
        {
            if (value == null)
            {
                throw new Exception("null value not allowed.");
            }

            _value = value;
        }
    }

    public static implicit operator T(NotNull<T> notNullValue)
    {
        return notNullValue.Value;
    }

    public static implicit operator NotNull<T>(T value)
    {
        return new NotNull<T> { Value = value };
    }
}

You would use very similar to the same way you would use Nullable<T>, except with the goal of accomplishing exactly the opposite - to not allow null. Here are some examples:

NotNull<Person> person = null; // throws exception
NotNull<Person> person = new Person(); // OK
NotNull<Person> person = GetPerson(); // throws exception if GetPerson() returns null

NotNull<T> is implicitly cast to and from T so you can use it just about anywhere you need it. For example, you can pass a Person object to a method that takes a NotNull<Person>:

Person person = new Person { Name = "John" };
WriteName(person);

public static void WriteName(NotNull<Person> person)
{
    Console.WriteLine(person.Value.Name);
}

As you can see above as with nullable you would access the underlying value through the Value property. Alternatively, you can use an explicit or implicit cast, you can see an example with the return value below:

Person person = GetPerson();

public static NotNull<Person> GetPerson()
{
    return new Person { Name = "John" };
}

Or you can even use it when the method just returns T (in this case Person) by doing a cast. For example, the following code would just like the code above:

Person person = (NotNull<Person>)GetPerson();

public static Person GetPerson()
{
    return new Person { Name = "John" };
}

Combine with Extension

Combine NotNull<T> with an extension method and you can cover even more situations. Here is an example of what the extension method can look like:

[System.Diagnostics.DebuggerNonUserCode]
public static class NotNullExtension
{
    public static T NotNull<T>(this T @this) where T: class
    {
        if (@this == null)
        {
            throw new Exception("null value not allowed");
        }

        return @this;
    }
}

And here is an example of how it could be used:

var person = GetPerson().NotNull();

GitHub

For your reference I made the code above available on GitHub, you can find it at:

https://github.com/luisperezphd/NotNull

Related Language Feature

C# 6.0 introduced the "null-conditional operator" that helps with this a little. With this feature, you can reference nested objects and if any one of them is null the whole expression returns null.

This reduces the number of null checks you have to do in some cases. The syntax is to put a question mark before each dot. Take the following code for example:

var address = country?.State?.County?.City;

Imagine that country is an object of type Country that has a property called State and so on. If country, State, County, or City is null then address will benull. Therefore you only have to check whetheraddressisnull`.

It's a great feature, but it gives you less information. It doesn't make it obvious which of the 4 is null.

Built-in like Nullable?

C# has a nice shorthand for Nullable<T>, you can make something nullable by putting a question mark after the type like so int?.

It would be nice if C# had something like the NotNull<T> struct above and had a similar shorthand, maybe the exclamation point (!) so that you could write something like: public void WriteName(Person! person).

Say your table is called t1 and your primary-key is called id
First, create the sequence:

create sequence t1_seq start with 1 increment by 1 nomaxvalue; 

Then create a trigger that increments upon insert:

create trigger t1_trigger
before insert on t1
for each row
   begin
     select t1_seq.nextval into :new.id from dual;
   end;

I am assuming you want to display this as part of the player.

This site breaks down how to get both the current and total time regardless of how you want to display it though using jQuery:

http://dev.opera.com/articles/view/custom-html5-video-player-with-css3-and-jquery/

This will also cover how to set it to a specific div. As philip has already mentioned, .currentTime will give you where you are in the video.

If you are using zsh do the following.

1. Open .zshrc file nano $HOME/.zshrc

2. You will see the commented $PATH variable here

   # If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/...

3. Remove the comment symbol(#) and append your new path using a separator(:) like this.

export PATH=$HOME/bin:/usr/local/bin:/Users/ebin/Documents/Softwares/mongoDB/bin:$PATH

4. Activate the change source $HOME/.zshrc

You're done !!!

There are different ways to do that.

• I created the data frame to showcase the different techniques to filter your data.

df = pd.DataFrame({'Date':['01-Jun-13','03-Jun-13', '15-Aug-13', '20-Jan-14', '21-Feb-14'],

'abc':[100,-20,40,25,60],'xyz':[200,50,-5,15,80] })

• I separated months/year/day and seperated month-year as you explained.

def getMonth(s):
  return s.split("-")[1]

def getDay(s):
  return s.split("-")[0]

def getYear(s):
  return s.split("-")[2]

def getYearMonth(s):
  return s.split("-")[1]+"-"+s.split("-")[2]

• I created new columns: year, month, day and 'yearMonth'. In your case, you need one of both. You can group using two columns 'year','month' or using one column yearMonth

df['year']= df['Date'].apply(lambda x: getYear(x))
df['month']= df['Date'].apply(lambda x: getMonth(x))
df['day']= df['Date'].apply(lambda x: getDay(x))
df['YearMonth']= df['Date'].apply(lambda x: getYearMonth(x))

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
3  20-Jan-14   25   15   14   Jan  20    Jan-14
4  21-Feb-14   60   80   14   Feb  21    Feb-14

• You can go through the different groups in groupby(..) items.

In this case, we are grouping by two columns:

for key,g in df.groupby(['year','month']):
    print key,g

Output:

('13', 'Jun')         Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
('13', 'Aug')         Date  abc  xyz year month day YearMonth
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
('14', 'Jan')         Date  abc  xyz year month day YearMonth
3  20-Jan-14   25   15   14   Jan  20    Jan-14
('14', 'Feb')         Date  abc  xyz year month day YearMonth

In this case, we are grouping by one column:

for key,g in df.groupby(['YearMonth']):
    print key,g

Output:

Jun-13         Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
Aug-13         Date  abc  xyz year month day YearMonth
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
Jan-14         Date  abc  xyz year month day YearMonth
3  20-Jan-14   25   15   14   Jan  20    Jan-14
Feb-14         Date  abc  xyz year month day YearMonth
4  21-Feb-14   60   80   14   Feb  21    Feb-14

• In case you wanna access to specific item, you can use get_group

print df.groupby(['YearMonth']).get_group('Jun-13')

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13

• Similar to get_group. This hack would help to filter values and get the grouped values.

This also would give the same result.

print df[df['YearMonth']=='Jun-13'] 

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13

You can select list of abc or xyz values during Jun-13

print df[df['YearMonth']=='Jun-13'].abc.values
print df[df['YearMonth']=='Jun-13'].xyz.values

Output:

[100 -20]  #abc values
[200  50]  #xyz values

You can use this to go through the dates that you have classified as "year-month" and apply cretiria on it to get related data.

for x in set(df.YearMonth): 
    print df[df['YearMonth']==x].abc.values
    print df[df['YearMonth']==x].xyz.values

I recommend also to check this answer as well.

I had the same problem, I succeeded by adding:

new \SoapClient(URI WSDL OR NULL if non-WSDL mode, [
    'cache_wsdl' => WSDL_CACHE_NONE, 
    'proxy_host' => 'URL PROXY',
    'proxy_port' => 'PORT PROXY'
]);

Hope this help :)

The only way is to use a formula or to format cells. The method i will use will be the following: Add another column next to these values. Then use the following formula:

=HOUR(A1)*60+MINUTE(A1)+SECOND(A1)/60

think works

Criteria criteria = getSession().createCriteria(clazz); 
Criterion rest1= Restrictions.and(Restrictions.eq(A, "X"), 
           Restrictions.in("B", Arrays.asList("X",Y)));
Criterion rest2= Restrictions.and(Restrictions.eq(A, "Y"), 
           Restrictions.eq(B, "Z"));
criteria.add(Restrictions.or(rest1, rest2));

ps -p <pid> -o %cpu,%mem,cmd

(You can leave off "cmd" but that might be helpful in debugging).

Note that this gives average CPU usage of the process over the time it has been running.

Use the phpinfo(); function to see the table of settings on your browser and look for the

Configuration File (php.ini) Path

and edit that file. Your computer can have multiple php.ini files, you want to edit the right one.

Also check display_errors = On, html_errors = On and error_reporting = E_ALL inside that file

Restart Apache.

urlencode: This differs from the » RFC 1738 encoding (see rawurlencode()) in that for historical reasons, spaces are encoded as plus (+) signs.

First we'll install @babel/cli, @babel/core and @babel/preset-env.

$ npm install --save-dev @babel/cli @babel/core @babel/preset-env

Then we'll create a .babelrc file for configuring babel.

$ touch .babelrc

This will host any options we might want to configure babel with.

{
  "presets": ["@babel/preset-env"]
}

With recent changes to babel, you will need to transpile your ES6 before node can run it.

So, we'll add our first script, build, in package.json.

"scripts": {
  "build": "babel index.js -d dist"
}

Then we'll add our start script in package.json.

"scripts": {
  "build": "babel index.js -d dist", // replace index.js with your filename
  "start": "npm run build && node dist/index.js"
}

Now let's start our server.

$ npm start

• The view controller is a UINavigationController
• The view controller is a UITabBarController

 while (true)
 {
     if (topViewController.presentedViewController) {
         topViewController = topViewController.presentedViewController;
     } else if ([topViewController isKindOfClass:[UINavigationController class]]) {
         UINavigationController *nav = (UINavigationController *)topViewController;
         topViewController = nav.topViewController;
     } else if ([topViewController isKindOfClass:[UITabBarController class]]) {
         UITabBarController *tab = (UITabBarController *)topViewController;
         topViewController = tab.selectedViewController;
     } else {
         break;
     }
 }

is simple for me use base64_encode

$term = base64_encode($term) 
$url = $youurl.'?term='.$term

after you decode the term

$term = base64_decode($['GET']['term'])

this way encode the "/" and "\"

You want to read raw lines to avoid problems with backslashes in the input (use -r):

while read -r line; do
   printf "<%s>\n" "$line"
done < file.txt

This will keep whitespace within the line, but removes leading and trailing whitespace. To keep those as well, set the IFS empty, as in

while IFS= read -r line; do
   printf "%s\n" "$line"
done < file.txt

This now is an equivalent of cat < file.txt as long as file.txt ends with a newline.

Note that you must double quote "$line" in order to keep word splitting from splitting the line into separate words--thus losing multiple whitespace sequences.

This is not politically correct but works

the link is broken, I put here other link that include @NickSweeting in the comments:

and you can get the data in json format:

http://ip-api.com/docs/api:json

This is a few months late but I thought I'd provide my solution based on this here tutorial. The gist of it is that it's a lot easier to manage once you change the way you approach forms.

First, use ReactiveFormsModule instead of or in addition to the normal FormsModule. With reactive forms you create your forms in your components/services and then plug them into your page instead of your page generating the form itself. It's a bit more code but it's a lot more testable, a lot more flexible, and as far as I can tell the best way to make a lot of non-trivial forms.

The end result will look a little like this, conceptually:

• You have one base FormGroup with whatever FormControl instances you need for the entirety of the form. For example, as in the tutorial I linked to, lets say you want a form where a user can input their name once and then any number of addresses. All of the one-time field inputs would be in this base form group.

• Inside that FormGroup instance there will be one or more FormArray instances. A FormArray is basically a way to group multiple controls together and iterate over them. You can also put multiple FormGroup instances in your array and use those as essentially "mini-forms" nested within your larger form.

• By nesting multiple FormGroup and/or FormControl instances within a dynamic FormArray, you can control validity and manage the form as one, big, reactive piece made up of several dynamic parts. For example, if you want to check if every single input is valid before allowing the user to submit, the validity of one sub-form will "bubble up" to the top-level form and the entire form becomes invalid, making it easy to manage dynamic inputs.

• As a FormArray is, essentially, a wrapper around an array interface but for form pieces, you can push, pop, insert, and remove controls at any time without recreating the form or doing complex interactions.

In case the tutorial I linked to goes down, here some sample code you can implement yourself (my examples use TypeScript) that illustrate the basic ideas:

Base Component code:

import { Component, Input, OnInit } from '@angular/core';
import { FormArray, FormBuilder, FormGroup, Validators } from '@angular/forms';

@Component({
  selector: 'my-form-component',
  templateUrl: './my-form.component.html'
})
export class MyFormComponent implements OnInit {
    @Input() inputArray: ArrayType[];
    myForm: FormGroup;

    constructor(private fb: FormBuilder) {}
    ngOnInit(): void {
        let newForm = this.fb.group({
            appearsOnce: ['InitialValue', [Validators.required, Validators.maxLength(25)]],
            formArray: this.fb.array([])
        });

        const arrayControl = <FormArray>newForm.controls['formArray'];
        this.inputArray.forEach(item => {
            let newGroup = this.fb.group({
                itemPropertyOne: ['InitialValue', [Validators.required]],
                itemPropertyTwo: ['InitialValue', [Validators.minLength(5), Validators.maxLength(20)]]
            });
            arrayControl.push(newGroup);
        });

        this.myForm = newForm;
    }
    addInput(): void {
        const arrayControl = <FormArray>this.myForm.controls['formArray'];
        let newGroup = this.fb.group({

            /* Fill this in identically to the one in ngOnInit */

        });
        arrayControl.push(newGroup);
    }
    delInput(index: number): void {
        const arrayControl = <FormArray>this.myForm.controls['formArray'];
        arrayControl.removeAt(index);
    }
    onSubmit(): void {
        console.log(this.myForm.value);
        // Your form value is outputted as a JavaScript object.
        // Parse it as JSON or take the values necessary to use as you like
    }
}

Sub-Component Code: (one for each new input field, to keep things clean)

import { Component, Input } from '@angular/core';
import { FormGroup } from '@angular/forms';

@Component({
    selector: 'my-form-sub-component',
    templateUrl: './my-form-sub-component.html'
})
export class MyFormSubComponent {
    @Input() myForm: FormGroup; // This component is passed a FormGroup from the base component template
}

Base Component HTML

<form [formGroup]="myForm" (ngSubmit)="onSubmit()" novalidate>
    <label>Appears Once:</label>
    <input type="text" formControlName="appearsOnce" />

    <div formArrayName="formArray">
        <div *ngFor="let control of myForm.controls['formArray'].controls; let i = index">
            <button type="button" (click)="delInput(i)">Delete</button>
            <my-form-sub-component [myForm]="myForm.controls.formArray.controls[i]"></my-form-sub-component>
        </div>
    </div>
    <button type="button" (click)="addInput()">Add</button>
    <button type="submit" [disabled]="!myForm.valid">Save</button>
</form>

Sub-Component HTML

<div [formGroup]="form">
    <label>Property One: </label>
    <input type="text" formControlName="propertyOne"/>

    <label >Property Two: </label>
    <input type="number" formControlName="propertyTwo"/>
</div>

In the above code I basically have a component that represents the base of the form and then each sub-component manages its own FormGroup instance within the FormArray situated inside the base FormGroup. The base template passes along the sub-group to the sub-component and then you can handle validation for the entire form dynamically.

Also, this makes it trivial to re-order component by strategically inserting and removing them from the form. It works with (seemingly) any number of inputs as they don't conflict with names (a big downside of template-driven forms as far as I'm aware) and you still retain pretty much automatic validation. The only "downside" of this approach is, besides writing a little more code, you do have to relearn how forms work. However, this will open up possibilities for much larger and more dynamic forms as you go on.

If you have any questions or want to point out some errors, go ahead. I just typed up the above code based on something I did myself this past week with the names changed and other misc. properties left out, but it should be straightforward. The only major difference between the above code and my own is that I moved all of the form-building to a separate service that's called from the component so it's a bit less messy.

Assuming you've checked the file is actually present on the server, this could also be caused by your web server restricting which file types are served:

• In Apache this could be done with with the <FilesMatch> directive or a RewriteRule if you're using mod_rewrite.
• In IIS you'd need to look to the Web.config file.

Answer to old question. But use ipython for this.

pip install ipython
ipython 
import imaplib
imaplib?

This will give the following output about imaplib package -

String form: <module 'imaplib' from '/usr/lib/python2.7/imaplib.py'>
File:        /usr/lib/python2.7/imaplib.py
Docstring:

This is going to be largely dependent on the RDBMS you're using, and whether a .NET option even exists for that RDBMS.

If you're using SQL Server, use the SqlBulkCopy class.

For other database vendors, try googling for them specifically. For example a search for ".NET Bulk insert into Oracle" turned up some interesting results, including this link back to Stack Overflow: Bulk Insert to Oracle using .NET.

Run change detection explicitly after the change:

import { ChangeDetectorRef } from '@angular/core';

constructor(private cdRef:ChangeDetectorRef) {}

ngAfterViewChecked()
{
  console.log( "! changement de la date du composant !" );
  this.dateNow = new Date();
  this.cdRef.detectChanges();
}

A SysOps guy once taught me the Three-Fingered Claw technique:

yell() { echo "$0: $*" >&2; }
die() { yell "$*"; exit 111; }
try() { "$@" || die "cannot $*"; }

These functions are *NIX OS and shell flavor-robust. Put them at the beginning of your script (bash or otherwise), try() your statement and code on.

Explanation

(based on flying sheep comment).

• yell: print the script name and all arguments to stderr:
  • $0 is the path to the script ;
  • $* are all arguments.
  • >&2 means > redirect stdout to & pipe 2. pipe 1 would be stdout itself.
• die does the same as yell, but exits with a non-0 exit status, which means “fail”.
• try uses the || (boolean OR), which only evaluates the right side if the left one failed.
  • $@ is all arguments again, but different.

You can get the server port from the

HttpServletRequest

@Autowired
private HttpServletRequest request;

@GetMapping(value = "/port")
public Object getServerPort() {
   System.out.println("I am from " + request.getServerPort());
   return "I am from  " + request.getServerPort();
}
    

Read the documentation.

I used a query like that:

WHERE
(
    date_trunc('day',table1.date_eval) = '2015-02-09'

$total_ratings is an array, which you can't use for a division.

From above:

$total_ratings = mysqli_fetch_array($result);

public function getdata(){
        $this->db->select('c.country_name as country, s.state_name as state, ct.city_name as city, t.id as id');
        $this->db->from('tblmaster t'); 
        $this->db->join('country c', 't.country=c.country_id');
        $this->db->join('state s', 't.state=s.state_id');
        $this->db->join('city ct', 't.city=ct.city_id');
        $this->db->order_by('t.id','desc');
        $query = $this->db->get();      
        return $query->result();
}

The accepted answer is correct as asked, below answers the opposite question of developing Android on VS Code.

Extensions

• Android : https://github.com/adelphes/android-dev-ext
• Emulator: https://github.com/DiemasMichiels/Emulator

Ultimately you can automate building and running your app on a device emulator by adding the function below to your $PATH and running runDebugApp <module> <start activity> from the integrated terminal:

# run android app
# usage runDebugApp [module] [fully qualified start activity com.package/com.package.MainActivity]
function runDebugApp(){
  ./gradlew -offline :"$1":installDebug && adb shell am start "$2" && adb logcat -d > logcat.log
}

With Android O the behaviour of the ANDROID_ID will change. The ANDROID_ID will be different per app per user on the phone.

Taken from: https://android-developers.googleblog.com/2017/04/changes-to-device-identifiers-in.html

Android ID

In O, Android ID (Settings.Secure.ANDROID_ID or SSAID) has a different value for each app and each user on the device. Developers requiring a device-scoped identifier, should instead use a resettable identifier, such as Advertising ID, giving users more control. Advertising ID also provides a user-facing setting to limit ad tracking.

Additionally in Android O:

• The ANDROID_ID value won't change on package uninstall/reinstall, as long as the package name and signing key are the same. Apps can rely on this value to maintain state across reinstalls.
• If an app was installed on a device running an earlier version of Android, the Android ID remains the same when the device is updated to Android O, unless the app is uninstalled and reinstalled.
• The Android ID value only changes if the device is factory reset or if the signing key rotates between uninstall and
  reinstall events.
• This change is only required for device manufacturers shipping with Google Play services and Advertising ID. Other device manufacturers may provide an alternative resettable ID or continue to provide ANDROID ID.

If you understand the difference between scope and session then it will be very easy to understand these methods.

A very nice blog post by Adam Anderson describes this difference:

Session means the current connection that's executing the command.

Scope means the immediate context of a command. Every stored procedure call executes in its own scope, and nested calls execute in a nested scope within the calling procedure's scope. Likewise, a SQL command executed from an application or SSMS executes in its own scope, and if that command fires any triggers, each trigger executes within its own nested scope.

Thus the differences between the three identity retrieval methods are as follows:

@@identity returns the last identity value generated in this session but any scope.

scope_identity() returns the last identity value generated in this session and this scope.

ident_current() returns the last identity value generated for a particular table in any session and any scope.

In this Question, best answer not work for me. After that i found this method to show listview footer,

LayoutInflater inflater = getLayoutInflater();
ViewGroup footerView = (ViewGroup)inflater.inflate(R.layout.footer_layout,listView,false);
listView.addFooterView(footerView, null, false);

And create new layout call footer_layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <TextView
        android:id="@+id/tv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Done"
        android:textStyle="italic"
        android:background="#d6cf55"
        android:padding="10dp"/>
</LinearLayout>

If not work refer this article hear

        // TODO Auto-generated method stub

          double theta = lon1 - lon2;
          double dist = Math.sin(deg2rad(lat1)) * Math.sin(deg2rad(lat2)) + Math.cos(deg2rad(lat1)) * Math.cos(deg2rad(lat2)) * Math.cos(deg2rad(theta));
          dist = Math.acos(dist);

          dist = dist * 60 * 1.1515;
          if (sr.equals("K")) {
            dist = dist * 1.609344;
          } else if (sr.equals("N")) {

          return (rad * 180.0 / Math.PI);
        }


    }

For a good cross-browser behavior, and understandable code, best is to use the onchange attribute in combination of a form:

function showVal(){
  valBox.innerHTML = inVal.value;
}

<form onchange="showVal()">
  <input type="range" min="5" max="10" step="1" id="inVal">
</form>

<span id="valBox"></span>

The same using oninput, the value is changed directly.

function showVal(){
  valBox.innerHTML = inVal.value;
}

<form oninput="showVal()">
  <input type="range" min="5" max="10" step="1" id="inVal">
</form>

<span id="valBox"></span>

Although Google uses BigTable for all their main applications, they also use MySQL for other (perhaps minor) apps.

For anybody coming here looking for a getTickCount() implementation for iOS, here is mine after putting various sources together.

Previously I had a bug in this code (I divided by 1000000 first) which was causing some quantisation of the output on my iPhone 6 (perhaps this was not an issue on iPhone 4/etc or I just never noticed it). Note that by not performing that division first, there is some risk of overflow if the numerator of the timebase is quite large. If anybody is curious, there is a link with much more information here: https://stackoverflow.com/a/23378064/588476

In light of that information, maybe it is safer to use Apple's function CACurrentMediaTime!

I also benchmarked the mach_timebase_info call and it takes approximately 19ns on my iPhone 6, so I removed the (not threadsafe) code which was caching the output of that call.

#include <mach/mach.h>
#include <mach/mach_time.h>

uint64_t getTickCount(void)
{
    mach_timebase_info_data_t sTimebaseInfo;
    uint64_t machTime = mach_absolute_time();

    // Convert to milliseconds
    mach_timebase_info(&sTimebaseInfo);
    machTime *= sTimebaseInfo.numer;
    machTime /= sTimebaseInfo.denom;
    machTime /= 1000000; // convert from nanoseconds to milliseconds

    return machTime;
}

Do be aware of the potential risk of overflow depending on the output of the timebase call. I suspect (but do not know) that it might be a constant for each model of iPhone. on my iPhone 6 it was 125/3.

The solution using CACurrentMediaTime() is quite trivial:

uint64_t getTickCount(void)
{
    double ret = CACurrentMediaTime();
    return ret * 1000;
}

Another easiest solution is to use Key.RETUEN

Not quite, the AND has to be lower-case.

<xsl:when test="4 &lt; 5 and 1 &lt; 2">
<!-- do something -->
</xsl:when>

Assuming that you have a collection ${roles} of the elements to put in the combo, and ${selected} the selected element, It would go like this:

<select name='role'>
    <option value="${selected}" selected>${selected}</option>
    <c:forEach items="${roles}" var="role">
        <c:if test="${role != selected}">
            <option value="${role}">${role}</option>
        </c:if>
    </c:forEach>
</select>

UPDATE (next question)

You are overwriting the attribute "productSubCategoryName". At the end of the for loop, the last productSubCategoryName.

Because of the limitations of the expression language, I think the best way to deal with this is to use a map:

Map<String,Boolean> map = new HashMap<String,Boolean>();
for(int i=0;i<userProductData.size();i++){
    String productSubCategoryName=userProductData.get(i).getProductSubCategory();
    System.out.println(productSubCategoryName);
    map.put(productSubCategoryName, true);
}
request.setAttribute("productSubCategoryMap", map);

And then in the JSP:

<select multiple="multiple" name="prodSKUs">
    <c:forEach items="${productSubCategoryList}" var="productSubCategoryList">
        <option value="${productSubCategoryList}" ${not empty productSubCategoryMap[productSubCategoryList] ? 'selected' : ''}>${productSubCategoryList}</option>
    </c:forEach>
</select>

Google has made some changes since this question was originally posted.

Here is my currently working example.

    public function update_token($token){

    try {

        $client = new Google_Client();
        $client->setAccessType("offline"); 
        $client->setAuthConfig(APPPATH . 'vendor' . DIRECTORY_SEPARATOR . 'google' . DIRECTORY_SEPARATOR . 'client_secrets.json');  
        $client->setIncludeGrantedScopes(true); 
        $client->addScope(Google_Service_Calendar::CALENDAR); 
        $client->setAccessToken($token);

        if ($client->isAccessTokenExpired()) {
            $refresh_token = $client->getRefreshToken();
            if(!empty($refresh_token)){
                $client->fetchAccessTokenWithRefreshToken($refresh_token);      
                $token = $client->getAccessToken();
                $token['refresh_token'] = json_decode($refresh_token);
                $token = json_encode($token);
            }
        }

        return $token;

    } catch (Exception $e) { 
        $error = json_decode($e->getMessage());
        if(isset($error->error->message)){
            log_message('error', $error->error->message);
        }
    }

• Step 1. Install homebrew from here: http://brew.sh
• Step 1.1. Run export PATH=/usr/local/bin:$PATH
• Step 2. Run brew update
• Step 3. Run brew install vim && brew install macvim
• Step 4. Run brew link macvim

You now have the latest versions of vim and macvim managed by brew. Run brew update && brew upgrade every once in a while to upgrade them.

This includes the installation of the CLI mvim and the mac application (which both point to the same thing).

I use this setup and it works like a charm. Brew even takes care of installing vim with the preferable options.

per @dantheta's comment:

As of npm 1.1.65, Github URL can be more concise user/project. npmjs.org/doc/files/package.json.html You can attach the branch like user/project#branch

So

"babel-eslint": "babel/babel-eslint",

Or for tag v1.12.0 on jscs:

"jscs": "jscs-dev/node-jscs#v1.12.0",

Note, if you use npm --save, you'll get the longer git

From https://docs.npmjs.com/cli/v6/configuring-npm/package-json#git-urls-as-dependencies

Git URLs as Dependencies

Git urls are of the form:

git+ssh://[email protected]:npm/cli.git#v1.0.27 git+ssh://[email protected]:npm/cli#semver:^5.0 git+https://[email protected]/npm/cli.git
git://github.com/npm/cli.git#v1.0.27

If #<commit-ish> is provided, it will be used to clone exactly that commit. If > the commit-ish has the format #semver:<semver>, <semver> can be any valid semver range or exact version, and npm will look for any tags or refs matching that range in the remote repository, much as it would for a registry dependency. If neither #<commit-ish> or #semver:<semver> is specified, then master is used.

GitHub URLs

As of version 1.1.65, you can refer to GitHub urls as just "foo": "user/foo-project". Just as with git URLs, a commit-ish suffix can be included. For example:

{
 "name": "foo",
 "version": "0.0.0",
 "dependencies": {
   "express": "expressjs/express",
   "mocha": "mochajs/mocha#4727d357ea",
   "module": "user/repo#feature\/branch"
 }
}```

There are at least 5 ways to do this:

If you want to convert to integers only, another fast (and short) way is the double-bitwise not (i.e. using two tilde characters):

e.g.

~~x;

Reference: http://james.padolsey.com/cool-stuff/double-bitwise-not/

The 5 common ways I know so far to convert a string to a number all have their differences (there are more bitwise operators that work, but they all give the same result as ~~). This JSFiddle shows the different results you can expect in the debug console: http://jsfiddle.net/TrueBlueAussie/j7x0q0e3/22/

The ~~x version results in a number in "more" cases, where others often result in undefined, but it fails for invalid input (e.g. it will return 0 if the string contains non-number characters after a valid number).

Overflow

Please note: Integer overflow and/or bit truncation can occur with ~~, but not the other conversions. While it is unusual to be entering such large values, you need to be aware of this. Example updated to include much larger values.

Some Perf tests indicate that the standard parseInt and parseFloat functions are actually the fastest options, presumably highly optimised by browsers, but it all depends on your requirement as all options are fast enough: http://jsperf.com/best-of-string-to-number-conversion/37

This all depends on how the perf tests are configured as some show parseInt/parseFloat to be much slower.

My theory is:

• Lies
• Darn lines
• Statistics
• JSPerf results :)

It is a orphan branch if it has no commit.

What's your problem with Tx logs? They grow? Then just set truncate on checkpoint option.

From Microsoft documentation:

In SQL Server 2000 or in SQL Server 2005, the "Simple" recovery model is equivalent to "truncate log on checkpoint" in earlier versions of SQL Server. If the transaction log is truncated every time a checkpoint is performed on the server, this prevents you from using the log for database recovery. You can only use full database backups to restore your data. Backups of the transaction log are disabled when the "Simple" recovery model is used.

Thank you for posting this question which is quite interesting, even in 2019 (Indeed, it is not easy to renew the shell cmd since it is a single instance as mentioned above), because renewing environment variables in windows allows to accomplish many automation tasks without having to manually restart the command line.

For example, we use this to allow software to be deployed and configured on a large number of machines that we reinstall regularly. And I must admit that having to restart the command line during the deployment of our software would be very impractical and would require us to find workarounds that are not necessarily pleasant. Let's get to our problem. We proceed as follows.

1 - We have a batch script that in turn calls a powershell script like this

[file: task.cmd].

cmd > powershell.exe -executionpolicy unrestricted -File C:\path_here\refresh.ps1

2 - After this, the refresh.ps1 script renews the environment variables using registry keys (GetValueNames(), etc.). Then, in the same powershell script, we just have to call the new environment variables available. For example, in a typical case, if we have just installed nodeJS before with cmd using silent commands, after the function has been called, we can directly call npm to install, in the same session, particular packages like follows.

[file: refresh.ps1]

function Update-Environment {
    $locations = 'HKLM:\SYSTEM\CurrentControlSet\Control\Session  Manager\Environment',
                 'HKCU:\Environment'
    $locations | ForEach-Object {
        $k = Get-Item $_
        $k.GetValueNames() | ForEach-Object {
            $name  = $_
            $value = $k.GetValue($_)

            if ($userLocation -and $name -ieq 'PATH') {
                $env:Path += ";$value"
            } else {

                Set-Item -Path Env:\$name -Value $value
            }
        }
        $userLocation = $true
    }
}
Update-Environment
#Here we can use newly added environment variables like for example npm install.. 
npm install -g create-react-app serve

Once the powershell script is over, the cmd script goes on with other tasks. Now, one thing to keep in mind is that after the task is completed, cmd has still no access to the new environment variables, even if the powershell script has updated those in its own session. Thats why we do all the needed tasks in the powershell script which can call the same commands as cmd of course.

HTTPS using Jersey client has two different version if you are using java 6 ,7 and 8 then

SSLContext sc = SSLContext.getInstance("SSL");

If using java 8 then

SSLContext sc = SSLContext.getInstance("TLSv1");
System.setProperty("https.protocols", "TLSv1");

Once you start running application will get Certificate error ,download certificate from browser and add into

C:\java-8\jdk1_8_0\jre\lib\security

Add into cacerts , you will get details in following links.

Few useful link to understand error

• http://www.9threes.com/2015/01/restful-java-client-with-jersey-client.html

  Java: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

  http://magicmonster.com/kb/prg/java/ssl/pkix_path_building_failed.html

  Java Keytool error after importing certificate , "keytool error: java.io.FileNotFoundException & Access Denied"

There is absolutely no way you can reliably check if there is an internet connection or not (I assume you mean access to the internet).

You can, however, request resources that are virtually never offline, like pinging google.com or something similar. I think this would be efficient.

try { 
    Ping myPing = new Ping();
    String host = "google.com";
    byte[] buffer = new byte[32];
    int timeout = 1000;
    PingOptions pingOptions = new PingOptions();
    PingReply reply = myPing.Send(host, timeout, buffer, pingOptions);
    return (reply.Status == IPStatus.Success);
}
catch (Exception) {
    return false;
}

Fix this by moving my jdk folder to other disk

If you have desired permissions saved to string then do

s = '660'
os.chmod(file_path, int(s, base=8))

See ?nchar. For example:

> nchar("foo")
[1] 3
> set.seed(10)
> strn <- paste(sample(LETTERS, 10), collapse = "")
> strn
[1] "NHKPBEFTLY"
> nchar(strn)
[1] 10

<ui:include>

Most basic way is <ui:include>. The included content must be placed inside <ui:composition>.

Kickoff example of the master page /page.xhtml:

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h:head>
        <title>Include demo</title>
    </h:head>
    <h:body>
        <h1>Master page</h1>
        <p>Master page blah blah lorem ipsum</p>
        <ui:include src="/WEB-INF/include.xhtml" />
    </h:body>
</html>

The include page /WEB-INF/include.xhtml (yes, this is the file in its entirety, any tags outside <ui:composition> are unnecessary as they are ignored by Facelets anyway):

<ui:composition 
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h2>Include page</h2>
    <p>Include page blah blah lorem ipsum</p>
</ui:composition>
  

This needs to be opened by /page.xhtml. Do note that you don't need to repeat <html>, <h:head> and <h:body> inside the include file as that would otherwise result in invalid HTML.

You can use a dynamic EL expression in <ui:include src>. See also How to ajax-refresh dynamic include content by navigation menu? (JSF SPA).

<ui:define>/<ui:insert>

A more advanced way of including is templating. This includes basically the other way round. The master template page should use <ui:insert> to declare places to insert defined template content. The template client page which is using the master template page should use <ui:define> to define the template content which is to be inserted.

Master template page /WEB-INF/template.xhtml (as a design hint: the header, menu and footer can in turn even be <ui:include> files):

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h:head>
        <title><ui:insert name="title">Default title</ui:insert></title>
    </h:head>
    <h:body>
        <div id="header">Header</div>
        <div id="menu">Menu</div>
        <div id="content"><ui:insert name="content">Default content</ui:insert></div>
        <div id="footer">Footer</div>
    </h:body>
</html>

Template client page /page.xhtml (note the template attribute; also here, this is the file in its entirety):

<ui:composition template="/WEB-INF/template.xhtml"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">

    <ui:define name="title">
        New page title here
    </ui:define>

    <ui:define name="content">
        <h1>New content here</h1>
        <p>Blah blah</p>
    </ui:define>
</ui:composition>

This needs to be opened by /page.xhtml. If there is no <ui:define>, then the default content inside <ui:insert> will be displayed instead, if any.

<ui:param>

You can pass parameters to <ui:include> or <ui:composition template> by <ui:param>.

<ui:include ...>
    <ui:param name="foo" value="#{bean.foo}" />
</ui:include>

<ui:composition template="...">
    <ui:param name="foo" value="#{bean.foo}" />
    ...
</ui:composition >

Inside the include/template file, it'll be available as #{foo}. In case you need to pass "many" parameters to <ui:include>, then you'd better consider registering the include file as a tagfile, so that you can ultimately use it like so <my:tagname foo="#{bean.foo}">. See also When to use <ui:include>, tag files, composite components and/or custom components?

You can even pass whole beans, methods and parameters via <ui:param>. See also JSF 2: how to pass an action including an argument to be invoked to a Facelets sub view (using ui:include and ui:param)?

Design hints

The files which aren't supposed to be publicly accessible by just entering/guessing its URL, need to be placed in /WEB-INF folder, like as the include file and the template file in above example. See also Which XHTML files do I need to put in /WEB-INF and which not?

There doesn't need to be any markup (HTML code) outside <ui:composition> and <ui:define>. You can put any, but they will be ignored by Facelets. Putting markup in there is only useful for web designers. See also Is there a way to run a JSF page without building the whole project?

The HTML5 doctype is the recommended doctype these days, "in spite of" that it's a XHTML file. You should see XHTML as a language which allows you to produce HTML output using a XML based tool. See also Is it possible to use JSF+Facelets with HTML 4/5? and JavaServer Faces 2.2 and HTML5 support, why is XHTML still being used.

CSS/JS/image files can be included as dynamically relocatable/localized/versioned resources. See also How to reference CSS / JS / image resource in Facelets template?

You can put Facelets files in a reusable JAR file. See also Structure for multiple JSF projects with shared code.

For real world examples of advanced Facelets templating, check the src/main/webapp folder of Java EE Kickoff App source code and OmniFaces showcase site source code.

Assuming the original date is in cell A1:

=DATE(YEAR(A1), MONTH(A1), DAY(A1)-180)

You are doing everything right by using a to_date function and specifying the time. The time is there in the database. The trouble is just that when you select a column of DATE datatype from the database, the default format mask doesn't show the time. If you issue a

alter session set nls_date_format = 'dd/MON/yyyy hh24:mi:ss'

or something similar including a time component, you will see that the time successfully made it into the database.

Though I upvoted the answer marked as correct. I wanted to touch on a few things for anyone stumbling upon this.

In general, if you're filtering specifically on Date values alone. Microsoft recommends using the language neutral format of ymd or y-m-d.

Note that the form '2007-02-12' is considered language-neutral only for the data types DATE, DATETIME2, and DATETIMEOFFSET.

To do a date comparison using the aforementioned approach is simple. Consider the following, contrived example.

--112 is ISO format 'YYYYMMDD'
declare @filterDate char(8) = CONVERT(char(8), GETDATE(), 112)

select 
    * 
from 
    Sales.Orders
where
    CONVERT(char(8), OrderDate, 112) = @filterDate

In a perfect world, performing any manipulation to the filtered column should be avoided because this can prevent SQL Server from using indexes efficiently. That said, if the data you're storing is only ever concerned with the date and not time, consider storing as DATETIME with midnight as the time. Because:

When SQL Server converts the literal to the filtered column’s type, it assumes midnight when a time part isn’t indicated. If you want such a filter to return all rows from the specified date, you need to ensure that you store all values with midnight as the time.

Thus, assuming you are only concerned with date, and store your data as such. The above query can be simplified to:

--112 is ISO format 'YYYYMMDD'
declare @filterDate char(8) = CONVERT(char(8), GETDATE(), 112)

select 
    * 
from 
    Sales.Orders
where
    OrderDate = @filterDate

This error can surface because of following two reasons:

• There is no room in the memory to accommodate new threads.

• The number of threads exceeds the Operating System limit.

I doubt that number of thread have exceeded the limit for the java process

So possibly chances are the issue is because of memory One point to consider is

threads are not created within the JVM heap. They are created outside the JVM heap. So if there is less room left in the RAM, after the JVM heap allocation, application will run into “java.lang.OutOfMemoryError: unable to create new native thread”.

Possible Solution is to reduce the heap memory or increase the overall ram size

Because your button is in control it could be that there is a validation from another control that don't allow the button to submit. The result in my case was to add CausesValidation property to the button:

<asp:Button ID="btn_QuaSave" runat="server" Text="SAVE" OnClick="btn_QuaSave_Click" CausesValidation="False"/> 

From java specification :

The floating-point types are float and double, which are conceptually associated with the single-precision 32-bit and double-precision 64-bit format IEEE 754 values and operations as specified in IEEE Standard for Binary Floating-Point Arithmetic, ANSI/IEEE Standard 754-1985 (IEEE, New York).

As it's hard to do anything with numbers without understanding IEEE754 basics, here's another link.

It's important to understand that the precision isn't uniform and that this isn't an exact storage of the numbers as is done for integers.

An example :

double a = 0.3 - 0.1;
System.out.println(a);          

prints

0.19999999999999998

If you need arbitrary precision (for example for financial purposes) you may need Big Decimal.

Also make sense to provide Boost version: This will modify original strings.

#include <boost/algorithm/string.hpp>

string str1 = "hello world!!!";
string str2 = "HELLO";
boost::algorithm::to_lower(str1)
boost::algorithm::to_lower(str2)

if (str1.find(str2) != std::string::npos)
{
    // str1 contains str2
}

or using perfect boost xpression library

#include <boost/xpressive/xpressive.hpp>
using namespace boost::xpressive;
....
std::string long_string( "very LonG string" );
std::string word("long");
smatch what;
sregex re = sregex::compile(word, boost::xpressive::icase);
if( regex_match( long_string, what, re ) )
{
    cout << word << " found!" << endl;
}

In this example you should pay attention that your search word don't have any regex special characters.

Consider an example,

class Animal {
    public void eat(String str) {
        System.out.println("Eating for grass");
    }
}

class Goat extends Animal {
    public void eat(String str) {
        System.out.println("blank");
    }
}

class Another extends Goat{
  public void eat(String str) {
        System.out.println("another");
  }
}

public class InheritanceSample {
    public static void main(String[] args) {
        Animal a = new Animal();
        Another t5 = (Another) new Goat();
    }
}

At Another t5 = (Another) new Goat(): you will get a ClassCastException because you cannot create an instance of the Another class using Goat.

Note: The conversion is valid only in cases where a class extends a parent class and the child class is casted to its parent class.

How to deal with the ClassCastException:

1. Be careful when trying to cast an object of a class into another class. Ensure that the new type belongs to one of its parent classes.
2. You can prevent the ClassCastException by using Generics, because Generics provide compile time checks and can be used to develop type-safe applications.

Source of the Note and the Rest

This issue happened for me when I had multiple targets in one project, and I changed the CFBundleExecutable plist property to something other than the target's name.

So, for example, I had the following targets in one project:

• SomeApp
• SomeApp WatchKit Extension
• SomeApp WatchKit App
• SomeApp Today Widget
• SomeApp for OS X (this is the target where the codesign error happens)

SomeApp for OS X had its CFBundleExecutable property set to just SomeApp, which not only conflicted with the first target called SomeApp but was different from the target it was meant for. Changing SomeApp for OS X to SomeApp and then renaming the first target worked fine for me.

Here is the Oracle solution (10g or higher). It uses the analytic function last_value() with the ignore nulls option, which substitutes the last non-null value for the column.

I got similar error after deleting a subproject, removed

"*compile project(path: ':MySubProject', configuration: 'android-endpoints')*"

in build.gradle (dependencies) under Gradle Scripts

I had the exact same error but with slightly different format and root-cause, and since this is the first Q&A that pops up when you search for "time data does not match format", I thought I'd leave the mistake I made for future viewers:

My initial code:

start = datetime.strptime('05-SEP-19 00.00.00.000 AM', '%d-%b-%y %I.%M.%S.%f %p')

Where I used %I to parse the hours and %p to parse 'AM/PM'.

The error:

ValueError: time data '05-SEP-19 00.00.00.000000 AM' does not match format '%d-%b-%y %I.%M.%S.%f %p'

I was going through the datetime docs and finally realized in 12-hour format %I, there is no 00... once I changed 00.00.00 to 12.00.00, the problem was resolved.

So it's either 01-12 using %I with %p, or 00-23 using %H.

Float.parseFloat() is the problem as it returns a new float.

Returns a new float initialized to the value represented by the specified String, as performed by the valueOf method of class Float.

You are formatting just for the purpose of display . It doesn't mean the float will be represented by the same format internally .

You can use java.lang.BigDecimal.

I am not sure why are you using parseFloat() twice. If you want to display the float in a certain format then just format it and display it.

Float litersOfPetrol=Float.parseFloat(stringLitersOfPetrol);
DecimalFormat df = new DecimalFormat("0.00");
df.setMaximumFractionDigits(2);
System.out.println("liters of petrol before putting in editor"+df.format(litersOfPetrol));

The error occurred when I unknowingly tried plotting the image path instead of the image.

My code :

import cv2 as cv
from matplotlib import pyplot as plt
import pytesseract
from resizeimage import resizeimage

img = cv.imread("D:\TemplateMatch\\fitting.png") ------>"THIS IS THE WRONG USAGE"
#cv.rectangle(img,(29,2496),(604,2992),(255,0,0),5)
plt.imshow(img)

Correction: img = cv.imread("fitting.png") --->THIS IS THE RIGHT USAGE"

Add this code below. Once turns it off, releases the filter. Second time turns it back on without filters.

Not very elegant, but served my purpose.

ActiveSheet.ListObjects("MyTable").Range.AutoFilter

'then call it again?
ActiveSheet.ListObjects("MyTable").Range.AutoFilter

You should use promises for async operations where you don't know when it will be completed. A promise "represents an operation that hasn't completed yet, but is expected in the future." (https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Promise)

An example implementation would be like:

myApp.factory('myService', function($http) {

    var getData = function() {

        // Angular $http() and then() both return promises themselves 
        return $http({method:"GET", url:"/my/url"}).then(function(result){

            // What we return here is the data that will be accessible 
            // to us after the promise resolves
            return result.data;
        });
    };


    return { getData: getData };
});


function myFunction($scope, myService) {
    var myDataPromise = myService.getData();
    myDataPromise.then(function(result) {  

       // this is only run after getData() resolves
       $scope.data = result;
       console.log("data.name"+$scope.data.name);
    });
}

Edit: Regarding Sujoys comment that What do I need to do so that myFuction() call won't return till .then() function finishes execution.

function myFunction($scope, myService) { 
    var myDataPromise = myService.getData(); 
    myDataPromise.then(function(result) { 
         $scope.data = result; 
         console.log("data.name"+$scope.data.name); 
    }); 
    console.log("This will get printed before data.name inside then. And I don't want that."); 
 }

Well, let's suppose the call to getData() took 10 seconds to complete. If the function didn't return anything in that time, it would effectively become normal synchronous code and would hang the browser until it completed.

With the promise returning instantly though, the browser is free to continue on with other code in the meantime. Once the promise resolves/fails, the then() call is triggered. So it makes much more sense this way, even if it might make the flow of your code a bit more complex (complexity is a common problem of async/parallel programming in general after all!)

Though this is an old post and have many answers, but here I have my version of code to upload the file to sharepoint 2013 using CSOM(c#)

I hope if you are working with downloading and uploading files then you know how to create Clientcontext object and Web object

/* Assuming you have created ClientContext object and Web object*/
string listTitle = "List title where you want your file to upload";
string filePath = "your file physical path";
List oList = web.Lists.GetByTitle(listTitle);
clientContext.Load(oList.RootFolder);//to load the folder where you will upload the file
FileCreationInformation fileInfo = new FileCreationInformation();

fileInfo.Overwrite = true;
fileInfo.Content = System.IO.File.ReadAllBytes(filePath);
fileInfo.Url = fileName;

File fileToUpload = fileCollection.Add(fileInfo);
clientContext.ExecuteQuery();

fileToUpload.CheckIn("your checkin comment", CheckinType.MajorCheckIn);
if (oList.EnableMinorVersions)
{
    fileToUpload.Publish("your publish comment");
    clientContext.ExecuteQuery();
}
if (oList.EnableModeration)
{
     fileToUpload.Approve("your approve comment"); 
}
clientContext.ExecuteQuery();

And here is the code for download

List oList = web.Lists.GetByTitle("ListNameWhereFileExist");
clientContext.Load(oList);
clientContext.Load(oList.RootFolder);
clientContext.Load(oList.RootFolder.Files);
clientContext.ExecuteQuery();
FileCollection fileCollection = oList.RootFolder.Files;
File SP_file = fileCollection.GetByUrl("fileNameToDownloadWithExtension");
clientContext.Load(SP_file);
clientContext.ExecuteQuery();                
var Local_stream = System.IO.File.Open("c:/testing/" + SP_file.Name, System.IO.FileMode.CreateNew);
var fileInformation = File.OpenBinaryDirect(clientContext, SP_file.ServerRelativeUrl);
var Sp_Stream = fileInformation.Stream;
Sp_Stream.CopyTo(Local_stream);

Still there are different ways I believe that can be used to upload and download.

Do everything suggested by ziesemer.

You may also want to :

• Stop the Oracle-related services (before deleting them from the registry).
• In the registry, look not only for entries named "Oracle" but also e.g. for "ODP".

I had the same error when was trying to write an image in DCIM/camera folder on Galaxy S5 (android 6.0.1) and I figured out that only this folder is restricted. I simply could write into DCIM/any folder but not in camera. This should be brand based restriction/customization.

Without explicitly defining the height I determined I need to apply the flex value to the parent and grandparent div elements...

<div style="display: flex;">
<div style="display: flex;">
 <img alt="No, he'll be an engineer." src="theknack.png" style="margin: auto;" />
</div>
</div>

If you're using a single element (e.g. dead-centered text in a single flex element) use the following:

align-items: center;
display: flex;
justify-content: center;

You can, if they are uploaded. Generally they are called "frameworkname-version-source(s)"

Hey If you want to print selected area or div ,Try This.

<style type="text/css">
@media print
{
body * { visibility: hidden; }
.div2 * { visibility: visible; }
.div2 { position: absolute; top: 40px; left: 30px; }
}
</style>

Hope it helps you

Pre:

for me the program with the Max call stack wasn't because of my code. It ended up being a different issue which caused the congestion in the flow of the application. So because I was trying to add too many items to mongoDB without any configuration chances the call stack issue was popping and it took me a few days to figure out what was going on....that said:

Following up with what @Jeff Lowery answered: I enjoyed this answer so much and it sped up the process of what I was doing by 10x at least.

I'm new at programming but I attempted to modularize the answer it. Also, didn't like the error being thrown so I wrapped it in a do while loop instead. If anything I did is incorrect, please feel free to correct me.

module.exports = function(object) {
    const { max = 1000000000n, fn } = object;
    let counter = 0;
    let running = true;
    Error.stackTraceLimit = 100;
    const A = (fn) => {
        fn();
        flipper = B;
    };
    const B = (fn) => {
        fn();
        flipper = A;
    };
    let flipper = B;
    const then = process.hrtime.bigint();
    do {
        counter++;
        if (counter > max) {
            const now = process.hrtime.bigint();
            const nanos = now - then;
            console.log({ 'runtime(sec)': Number(nanos) / 1000000000.0 });
            running = false;
        }
        flipper(fn);
        continue;
    } while (running);
};

.overflow-wrap-hack{

Benefits:

• Uses overflow-wrap:break-word instead of word-break:break-all. Which is better because it tries to break on spaces first, and cuts the word off only if the word is bigger than it's container.
• No table-layout:fixed needed. Use your regular auto-sizing.
• Not needed to define fixed width or fixed max-width in pixels. Define % of the parent if needed.

            ->where('u.id = ?2')
            ->setParameter(2, $qb->expr()->literal($userId))
            ->getQuery()
            ->getSingleScalarResult()
        ;
    }

AJAX action handling:

# Post datas may be:
# handled with a specific custom formType — OR — retrieved from request object
$userId = (int)$request->request->get('userId');
$newStatus = (int)$request->request->get('newStatus');
$em = $this->getDoctrine()->getManager();
$r = $em->getRepository('NAMESPACE\User')
        ->updateUserStatus($userId, $newStatus);
if ( !empty($r) ){
    # Row updated
}

Working example using Doctrine 2.5 (on top of Symfony3).

As of year 2020, JetBrains suggests to commit the .idea folder.
The JetBrains IDEs (webstorm, intellij, android studio, pycharm, clion, etc.) automatically add that folder to your git repository (if there's one).
Inside the folder .idea, has been already created a .gitignore, updated by the IDE itself to avoid to commit user related settings that may contains privacy/password data.

It is safe (and usually useful) to commit the .idea folder.

Since the question mentioned third-party libraries and not all packages then you probably want to fall back to using wildcards.

A use case being: I just want to update all my packages that are obtained from the Github VCS, then you would just say:

go get -u github.com/... // ('...' being the wildcard). 

This would go ahead and only update your github packages in the current $GOPATH

Same applies for within a VCS too, say you want to only upgrade all the packages from ogranizaiton A's repo's since as they have released a hotfix you depend on:

go get -u github.com/orgA/...

How about:

String.prototype.strcmp = function(s) {
    if (this < s) return -1;
    if (this > s) return 1;
    return 0;
}

Then, to compare s1 with 2:

s1.strcmp(s2)

If this happend to your XAMPP installation, just copy global_priv.MAD and global_priv.MAI files from ./xampp/mysql/backup/mysql/ to ./xampp/mysql/data/mysql/.

To setup the http proxy have the -g flag set:

sudo npm config set proxy http://proxy_host:port -g

For https proxy, again make sure the -g flag is set:

sudo npm config set https-proxy http://proxy_host:port -g

I met this issue this morning because I used the same executable in DIFFERENT OSes: after compiling my program with gcc -ggdb -Wall test.c -o test in my Mac(10.15.2), I ran gdb with the executable in Ubuntu(16.04) in my VirtualBox.

Fix: recompile with the same command under Ubuntu, then you should be good.

You can try this:

function Get-UrlStatusCode([string] $Url)
{
    try
    {
        (Invoke-WebRequest -Uri $Url -UseBasicParsing -DisableKeepAlive).StatusCode
    }
    catch [Net.WebException]
    {
        [int]$_.Exception.Response.StatusCode
    }
}

$statusCode = Get-UrlStatusCode 'httpstat.us/500'

The dot operator . does not need to be escaped inside of a character class [].

The answers so far have been correct, but here is some additional information:

One can safely rename a branch with '-m' (move), but one has to be careful with '-M', because it forces the rename, even if there is an existing branch with the same name already. Here is the excerpt from the 'git-branch' man page:

With a -m or -M option, <oldbranch> will be renamed to <newbranch>. If <oldbranch> had a corresponding reflog, it is renamed to match <newbranch>, and a reflog entry is created to remember the branch renaming. If <newbranch> exists, -M must be used to force the rename to happen.

Answering this just in case if someone else like me stumbles upon this post among many that advise use of JavaScripts for changing iframe height to 100%.

I strongly recommend that you see and try this option specified at How do you give iframe 100% height before resorting to a JavaScript based option. The referenced solution works perfectly for me in all of the testing I have done so far. Hope this helps someone.

This is more an add-on to the best answer above (GZip Compression can be enabled directly through IIS) which is correct if your running IIS on Windows desktop however...

If your running IIS on Windows Server, this content compression feature is found in a different place to desktop Windows (not in programs and features in Control Panel). First open "Server Manager" then click Manage -> "Add Roles & Features" then keep clicking NEXT (make sure you select the correct server when you see the list of servers if your managing multiple servers from this instance) until you get to SERVER ROLES, scroll down to and open "Web Server (IIS)..." then "Web Server" then "Performance" then tick "Dynamic Content Compression" then click INSTALL. I tested this on Server 2016 Standard so there may be slight differences if your on an earlier version of Server.

Then follow the instructions from Testing - Check if GZIP Compression is Enabled

Try this, at the end of the each loop, ids array will contain all the hexcodes.

var ids = [];

    $(document).ready(function($) {
    var $div = $("<div id='hexCodes'></div>").appendTo(document.body), code;
    $(".color_cell").each(function() {
        code = $(this).attr('id');
        ids.push(code);
        $div.append(code + "<br />");
    });



});

parser.add_argument also has a switch required. You can use required=False. Here is a sample snippet with Python 2.7:

parser = argparse.ArgumentParser(description='get dir')
parser.add_argument('--dir', type=str, help='dir', default=os.getcwd(), required=False)
args = parser.parse_args()

Following advice from comments I utilize Docker systemd documentation to improve this answer. Below procedure doesn't require reboot and is much cleaner.

First create directory and file for custom configuration:

sudo mkdir -p /etc/systemd/system/docker.service.d
sudo $EDITOR /etc/systemd/system/docker.service.d/docker-storage.conf

For docker version before 17.06-ce paste:

[Service]
ExecStart=
ExecStart=/usr/bin/docker daemon -H fd:// --graph="/mnt"

For docker after 17.06-ce paste:

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H fd:// --data-root="/mnt"

Alternative method through daemon.json

I recently tried above procedure with 17.09-ce on Fedora 25 and it seem to not work. Instead of that simple modification in /etc/docker/daemon.json do the trick:

{
    "graph": "/mnt",
    "storage-driver": "overlay"
}

Despite the method you have to reload configuration and restart Docker:

sudo systemctl daemon-reload
sudo systemctl restart docker

To confirm that Docker was reconfigured:

docker info|grep "loop file"

In recent version (17.03) different command is required:

docker info|grep "Docker Root Dir"

Output should look like this:

 Data loop file: /mnt/devicemapper/devicemapper/data
 Metadata loop file: /mnt/devicemapper/devicemapper/metadata

Or:

 Docker Root Dir: /mnt

Then you can safely remove old Docker storage:

rm -rf /var/lib/docker

@echo off

echo Type your text here.

:top

set /p boompanes=

pause

echo %boompanes%> practice.txt

hope this helps. you should change the string names(IDK what its called) and the file name

First of all ASIDE is to be used only to denote related content to main content, not for a generic sidebar. Second, one aside for each sidebar only

You will have only one aside for each sidebar. Elements of a sidebar are divs or sections inside a aside.

I would go with Option 1: Aside with sections

<aside id="sidebar">
    <section id="widget_1"></section>
    <section id="widget_2"></section>
    <section id="widget_3"></section>
</aside>

Here is the spec https://developer.mozilla.org/en-US/docs/Web/HTML/Element/aside

Again use section only if they have a header or footer in them, otherwise use a plain div.

In Visual Studio 2015 this shortcut opens a preview of the definition which even works through typedefs and #defines.

Ctrl + , (comma)

Use:

ToolTip tip = new ToolTip();
private void richTextBox1_MouseMove(object sender, MouseEventArgs e)
{
    Cursor a = System.Windows.Forms.Cursor.Current;
    if (a == Cursors.Hand)
    {
        Point p = richTextBox1.Location;
        tip.Show(
            GetWord(richTextBox1.Text,
                richTextBox1.GetCharIndexFromPosition(e.Location)),
            this,
            p.X + e.X,
            p.Y + e.Y + 32,
            1000);
    }
}

Use the GetWord function from my other answer to get the hovered word. Use timer logic to disable reshow the tooltip as in prev. example.

In this example right above, the tool tip shows the hovered word by checking the mouse pointer.

If this answer is still not what you are looking fo, please specify the condition that characterizes the word you want to use tooltip on. If you want it for bolded word, please tell me.

One of my concerns with phpMyAdmin was that by default, all MySQL users can access the db. If DB's root password is compromised, someone can wreck havoc on the db. I wanted to find a way to avoid that by restricting which MySQL user can login to phpMyAdmin.

I have found using AllowDeny configuration in PhpMyAdmin to be very useful. http://wiki.phpmyadmin.net/pma/Config#AllowDeny_.28rules.29

AllowDeny lets you configure access to phpMyAdmin in a similar way to Apache. If you set the 'order' to explicit, it will only grant access to users defined in 'rules' section. In the rules, section you restrict MySql users who can access use the phpMyAdmin.

$cfg['Servers'][$i]['AllowDeny']['order'] = 'explicit'
$cfg['Servers'][$i]['AllowDeny']['rules'] = array('pma-user from all')

Now you have limited access to the user named pma-user in MySQL, you can grant limited privilege to that user.

grant select on db_name.some_table to 'pma-user'@'app-server'

I found this approach simple and useful: How to "merge" specific files from another branch

As it turns out, we’re trying too hard. Our good friend git checkout is the right tool for the job.

git checkout source_branch <paths>...

We can simply give git checkout the name of the feature branch A and the paths to the specific files that we want to add to our master branch.

Please read the whole article for more understanding

Replace Require Local with Require all granted in xampp\apache\conf\extra\httpd-xampp.conf file.

Here is another drawable xml for those who want to add all together gradient background, corner radius and ripple effect:

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="@color/colorPrimaryDark">
    <item android:id="@android:id/mask">
        <shape android:shape="rectangle">
            <solid android:color="@color/colorPrimaryDark" />
            <corners android:radius="@dimen/button_radius_large" />
        </shape>
    </item>

    <item android:id="@android:id/background">
        <shape android:shape="rectangle">
            <gradient
                android:angle="90"
                android:endColor="@color/colorPrimaryLight"
                android:startColor="@color/colorPrimary"
                android:type="linear" />
            <corners android:radius="@dimen/button_radius_large" />
        </shape>
    </item>
</ripple>

Add this to the background of your button.

<Button
    ...
    android:background="@drawable/button_background" />

PS: this answer works for android api 21 and above.

Here is a working plunkr with a filter and sortBy pipe. https://plnkr.co/edit/vRvnNUULmBpkbLUYk4uw?p=preview

As developer033 mentioned in a comment, you are passing in a single value to the filter pipe, when the filter pipe is expecting an array of values. I would tell the pipe to expect a single value instead of an array

export class FilterPipe implements PipeTransform {
    transform(items: any[], term: string): any {
        // I am unsure what id is here. did you mean title?
        return items.filter(item => item.id.indexOf(term) !== -1);
    }
}

I would agree with DeborahK that impure pipes should be avoided for performance reasons. The plunkr includes console logs where you can see how much the impure pipe is called.

If you need the port number also, you can use

Request.Url.Authority

Example:

string url = Request.Url.Authority + HttpContext.Current.Request.RawUrl.ToString();

if (Request.ServerVariables["HTTPS"] == "on")
{
    url = "https://" + url;
}
else 
{
    url = "http://" + url;
}

With Swift 5, according to your needs, you may choose one of the 6 following Playground codes in order to solve your problem.

#1. Using subscript(_:) subscript

let array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
let arraySlice = array[..<5]
//let arraySlice = array[0..<5] // also works
//let arraySlice = array[0...4] // also works
//let arraySlice = array[...4] // also works
let newArray = Array(arraySlice)
print(newArray) // prints: ["A", "B", "C", "D", "E"]

#2. Using prefix(_:) method

Complexity: O(1) if the collection conforms to RandomAccessCollection; otherwise, O(k), where k is the number of elements to select from the beginning of the collection.

let array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
let arraySlice = array.prefix(5)
let newArray = Array(arraySlice)
print(newArray) // prints: ["A", "B", "C", "D", "E"]

Apple states for prefix(_:):

If the maximum length exceeds the number of elements in the collection, the result contains all the elements in the collection.

#3. Using prefix(upTo:) method

Complexity: O(1)

let array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
let arraySlice = array.prefix(upTo: 5)
let newArray = Array(arraySlice)
print(newArray) // prints: ["A", "B", "C", "D", "E"]

Apple states for prefix(upTo:):

Using the prefix(upTo:) method is equivalent to using a partial half-open range as the collection's subscript. The subscript notation is preferred over prefix(upTo:).

#4. Using prefix(through:) method

let array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
let arraySlice = array.prefix(through: 4)
let newArray = Array(arraySlice)
print(newArray) // prints: ["A", "B", "C", "D", "E"]

#5. Using removeSubrange(_:) method

Complexity: O(n), where n is the length of the collection.

var array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
array.removeSubrange(5...)
print(array) // prints: ["A", "B", "C", "D", "E"]

#6. Using dropLast(_:) method

Complexity: O(1) if the collection conforms to RandomAccessCollection; otherwise, O(k), where k is the number of elements to drop.

let array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
let distance = array.distance(from: 5, to: array.endIndex)
let arraySlice = array.dropLast(distance)
let newArray = Array(arraySlice)
print(newArray) // prints: ["A", "B", "C", "D", "E"]

It can be a mathematical convention in the definition of an interval where square brackets mean "extremal inclusive" and round brackets "extremal exclusive".

This is not a general solution but might help many of those who just typed "matplotlib surface plot" in Google and landed here.

Suppose you have data = [(x1,y1,z1),(x2,y2,z2),.....,(xn,yn,zn)], then you can get three 1-d lists using x, y, z = zip(*data). Now you can of course create 3d scatterplot using three 1-d lists.

But, why can't in general this data be used to create surface plot? To understand that consider an empty 3-d plot :

Now, suppose for each possible value of (x, y) on a "discrete" regular grid, you have a z value, then there's no issue & you can in fact get a surface plot:

import numpy as np
from matplotlib import pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
from matplotlib import cm

x = np.linspace(0, 10, 6)  # [0, 2,..,10] : 6 distinct values
y = np.linspace(0, 20, 5)  # [0, 5,..,20] : 5 distinct values
z = np.linspace(0, 100, 30)  # 6 * 5 = 30 values, 1 for each possible combination of (x,y)

X, Y = np.meshgrid(x, y)
Z = np.reshape(z, X.shape)  # Z.shape must be equal to X.shape = Y.shape

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

ax.plot_surface(X, Y, Z)

ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')
ax.set_zlabel('Z Label')
plt.show()

What's happens when you haven't got z for all possible combinations of (x, y)? Then at the point (at intersection of two black lines on x-y plane on blank plot above), we don't know what is the value of z. It could be anything, we don't know how 'high' or 'low' our surface should be at that point (although it can be approximated using other functions, surface_plot requires that you supply it arguments where X.shape = Y.shape = Z.shape).

I use EclipseLink. This JPA allows the following way for the native queries:

Query q = em.createNativeQuery("SELECT * FROM mytable where username = ?username");
q.setParameter("username", "test");
q.getResultList();

Your mobile class Isn't correct:

.mobile {
  display: none !important;
  visibility: hidden !important; //This is what's keeping the div from showing, remove this.
}

The best way in my eyes is to use the concat() method provided by the String class itself.

The useage would, in your case, look like this:

String myConcatedString = cursor.getString(numcol).concat('-').
       concat(cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE)));

char *p = "String";   means pointer to a string type variable.

char p3[5] = "String"; means you are pre-defining the size of the array to consist of no more than 5 elements. Note that,for strings the null "\0" is also considered as an element.So,this statement would give an error since the number of elements is 7 so it should be:

char p3[7]= "String";

You can use https://appery.io/ It is the same phonegap but in very convinient wrapper

To read a file from internal storage:

Call openFileInput() and pass it the name of the file to read. This returns a FileInputStream. Read bytes from the file with read(). Then close the stream with close().

code::

StringBuilder sb = new StringBuilder();
        try{
            BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line).append("\n");
            }
            is.close();
        } catch(OutOfMemoryError om){
            om.printStackTrace();
        } catch(Exception ex){
            ex.printStackTrace();
        }
        String result = sb.toString();

Leaving alone any debates over when (if ever) it should be done, @functions is how you do it.

@functions {

    // Add code here.

}

we also have had similar problems (we're behind a corporate proxy). changing to yarn at least on our jenkins builds made a huge difference.

there are some minor differences in the results between "npm install" and "yarn install" - but nothing that hurts us.

I recommend, you change your loop algorithm:

• Add the comma not AFTER the item, but BEFORE
• Use a boolean variable, that starts with false, do suppress the first comma
• Set this boolean variable to true after testing it

This might not be the answer you're looking for, but I don't have a better way for downloading DB from phone. What I will suggest is make sure you're using this mini-DDMS. It will be super hidden though if you don't click the very small camoflage box at the very bottom left of program. (tried to hover over it otherwise you might miss it.)

Also the drop down that says no filters (top right). It literally has a ton of different ways you can monitor different process/apps by PPID, name, and a lot more. I've always used this to monitor phone, but keep in mind I'm not doing the type of dev work that needs to be 120% positive the database isn't doing something out of the ordinary.

Hope it helps

i would do the same thing as Andy but i'ld use the 'empty' function.

like so:

if(empty($yourArray))
{echo"<p>There's nothing in the array.....</p>";}
else
{
foreach ($yourArray as $current_array_item)
  {
    //do something with the current array item here
  } 
}

Make that variable as transient.Your problem will get solved..

@Column(name="emp_name", nullable=false, length=30)
    private transient String empName;

You can do something like this:

.flex {_x000D_
  display: flex;_x000D_
  flex-direction: row;_x000D_
  flex-wrap: wrap;_x000D_
}_x000D_
_x000D_
.flex>div {_x000D_
  flex: 1 0 50%;_x000D_
}_x000D_
_x000D_
.flex>div:first-child {_x000D_
  flex: 0 1 100%;_x000D_
}

<div class="flex">_x000D_
  <div>Hi</div>_x000D_
  <div>Hello</div>_x000D_
  <div>Hello 2</div>_x000D_
</div>

Here is a demo: http://jsfiddle.net/73574emn/1/

This model relies on the line-wrap after one "row" is full. Since we set the first item's flex-basis to be 100% it fills the first row completely. Special attention on the flex-wrap: wrap;

Since React 16.8 in 2019 with useState and useEffect Hooks, following are now equivalent (in simple cases):

AngularJS:

$scope.name = 'misko'
$scope.$watch('name', getSearchResults)

<input ng-model="name" />

React:

const [name, setName] = useState('misko')
useEffect(getSearchResults, [name])

<input value={name} onChange={e => setName(e.target.value)} />

Interestingly most other answers suffer from these two problems:

• They focus on basic forms of join only
• They (ab)use Venn diagrams, which are an inaccurate tool for visualising joins (they're much better for unions).

I've recently written an article on the topic: A Probably Incomplete, Comprehensive Guide to the Many Different Ways to JOIN Tables in SQL, which I'll summarise here.

First and foremost: JOINs are cartesian products

This is why Venn diagrams explain them so inaccurately, because a JOIN creates a cartesian product between the two joined tables. Wikipedia illustrates it nicely:

The SQL syntax for cartesian products is CROSS JOIN. For example:

SELECT *

-- This just generates all the days in January 2017
FROM generate_series(
  '2017-01-01'::TIMESTAMP,
  '2017-01-01'::TIMESTAMP + INTERVAL '1 month -1 day',
  INTERVAL '1 day'
) AS days(day)

-- Here, we're combining all days with all departments
CROSS JOIN departments

Which combines all rows from one table with all rows from the other table:

Source:

+--------+   +------------+
| day    |   | department |
+--------+   +------------+
| Jan 01 |   | Dept 1     |
| Jan 02 |   | Dept 2     |
| ...    |   | Dept 3     |
| Jan 30 |   +------------+
| Jan 31 |
+--------+

Result:

+--------+------------+
| day    | department |
+--------+------------+
| Jan 01 | Dept 1     |
| Jan 01 | Dept 2     |
| Jan 01 | Dept 3     |
| Jan 02 | Dept 1     |
| Jan 02 | Dept 2     |
| Jan 02 | Dept 3     |
| ...    | ...        |
| Jan 31 | Dept 1     |
| Jan 31 | Dept 2     |
| Jan 31 | Dept 3     |
+--------+------------+

If we just write a comma separated list of tables, we'll get the same:

-- CROSS JOINing two tables:
SELECT * FROM table1, table2

INNER JOIN (Theta-JOIN)

An INNER JOIN is just a filtered CROSS JOIN where the filter predicate is called Theta in relational algebra.

For instance:

SELECT *

-- Same as before
FROM generate_series(
  '2017-01-01'::TIMESTAMP,
  '2017-01-01'::TIMESTAMP + INTERVAL '1 month -1 day',
  INTERVAL '1 day'
) AS days(day)

-- Now, exclude all days/departments combinations for
-- days before the department was created
JOIN departments AS d ON day >= d.created_at

Note that the keyword INNER is optional (except in MS Access).

(look at the article for result examples)

EQUI JOIN

A special kind of Theta-JOIN is equi JOIN, which we use most. The predicate joins the primary key of one table with the foreign key of another table. If we use the Sakila database for illustration, we can write:

SELECT *
FROM actor AS a
JOIN film_actor AS fa ON a.actor_id = fa.actor_id
JOIN film AS f ON f.film_id = fa.film_id

This combines all actors with their films.

Or also, on some databases:

SELECT *
FROM actor
JOIN film_actor USING (actor_id)
JOIN film USING (film_id)

The USING() syntax allows for specifying a column that must be present on either side of a JOIN operation's tables and creates an equality predicate on those two columns.

NATURAL JOIN

Other answers have listed this "JOIN type" separately, but that doesn't make sense. It's just a syntax sugar form for equi JOIN, which is a special case of Theta-JOIN or INNER JOIN. NATURAL JOIN simply collects all columns that are common to both tables being joined and joins USING() those columns. Which is hardly ever useful, because of accidental matches (like LAST_UPDATE columns in the Sakila database).

Here's the syntax:

SELECT *
FROM actor
NATURAL JOIN film_actor
NATURAL JOIN film

OUTER JOIN

Now, OUTER JOIN is a bit different from INNER JOIN as it creates a UNION of several cartesian products. We can write:

-- Convenient syntax:
SELECT *
FROM a LEFT JOIN b ON <predicate>

-- Cumbersome, equivalent syntax:
SELECT a.*, b.*
FROM a JOIN b ON <predicate>
UNION ALL
SELECT a.*, NULL, NULL, ..., NULL
FROM a
WHERE NOT EXISTS (
  SELECT * FROM b WHERE <predicate>
)

No one wants to write the latter, so we write OUTER JOIN (which is usually better optimised by databases).

Like INNER, the keyword OUTER is optional, here.

OUTER JOIN comes in three flavours:

• LEFT [ OUTER ] JOIN: The left table of the JOIN expression is added to the union as shown above.
• RIGHT [ OUTER ] JOIN: The right table of the JOIN expression is added to the union as shown above.
• FULL [ OUTER ] JOIN: Both tables of the JOIN expression are added to the union as shown above.

All of these can be combined with the keyword USING() or with NATURAL (I've actually had a real world use-case for a NATURAL FULL JOIN recently)

Alternative syntaxes

There are some historic, deprecated syntaxes in Oracle and SQL Server, which supported OUTER JOIN already before the SQL standard had a syntax for this:

-- Oracle
SELECT *
FROM actor a, film_actor fa, film f
WHERE a.actor_id = fa.actor_id(+)
AND fa.film_id = f.film_id(+)

-- SQL Server
SELECT *
FROM actor a, film_actor fa, film f
WHERE a.actor_id *= fa.actor_id
AND fa.film_id *= f.film_id

Having said so, don't use this syntax. I just list this here so you can recognise it from old blog posts / legacy code.

Partitioned OUTER JOIN

Few people know this, but the SQL standard specifies partitioned OUTER JOIN (and Oracle implements it). You can write things like this:

WITH

  -- Using CONNECT BY to generate all dates in January
  days(day) AS (
    SELECT DATE '2017-01-01' + LEVEL - 1
    FROM dual
    CONNECT BY LEVEL <= 31
  ),

  -- Our departments
  departments(department, created_at) AS (
    SELECT 'Dept 1', DATE '2017-01-10' FROM dual UNION ALL
    SELECT 'Dept 2', DATE '2017-01-11' FROM dual UNION ALL
    SELECT 'Dept 3', DATE '2017-01-12' FROM dual UNION ALL
    SELECT 'Dept 4', DATE '2017-04-01' FROM dual UNION ALL
    SELECT 'Dept 5', DATE '2017-04-02' FROM dual
  )
SELECT *
FROM days 
LEFT JOIN departments 
  PARTITION BY (department) -- This is where the magic happens
  ON day >= created_at

Parts of the result:

+--------+------------+------------+
| day    | department | created_at |
+--------+------------+------------+
| Jan 01 | Dept 1     |            | -- Didn't match, but still get row
| Jan 02 | Dept 1     |            | -- Didn't match, but still get row
| ...    | Dept 1     |            | -- Didn't match, but still get row
| Jan 09 | Dept 1     |            | -- Didn't match, but still get row
| Jan 10 | Dept 1     | Jan 10     | -- Matches, so get join result
| Jan 11 | Dept 1     | Jan 10     | -- Matches, so get join result
| Jan 12 | Dept 1     | Jan 10     | -- Matches, so get join result
| ...    | Dept 1     | Jan 10     | -- Matches, so get join result
| Jan 31 | Dept 1     | Jan 10     | -- Matches, so get join result

The point here is that all rows from the partitioned side of the join will wind up in the result regardless if the JOIN matched anything on the "other side of the JOIN". Long story short: This is to fill up sparse data in reports. Very useful!

SEMI JOIN

Seriously? No other answer got this? Of course not, because it doesn't have a native syntax in SQL, unfortunately (just like ANTI JOIN below). But we can use IN() and EXISTS(), e.g. to find all actors who have played in films:

SELECT *
FROM actor a
WHERE EXISTS (
  SELECT * FROM film_actor fa
  WHERE a.actor_id = fa.actor_id
)

The WHERE a.actor_id = fa.actor_id predicate acts as the semi join predicate. If you don't believe it, check out execution plans, e.g. in Oracle. You'll see that the database executes a SEMI JOIN operation, not the EXISTS() predicate.

ANTI JOIN

This is just the opposite of SEMI JOIN (be careful not to use NOT IN though, as it has an important caveat)

Here are all the actors without films:

SELECT *
FROM actor a
WHERE NOT EXISTS (
  SELECT * FROM film_actor fa
  WHERE a.actor_id = fa.actor_id
)

Some folks (especially MySQL people) also write ANTI JOIN like this:

SELECT *
FROM actor a
LEFT JOIN film_actor fa
USING (actor_id)
WHERE film_id IS NULL

I think the historic reason is performance.

LATERAL JOIN

OMG, this one is too cool. I'm the only one to mention it? Here's a cool query:

SELECT a.first_name, a.last_name, f.*
FROM actor AS a
LEFT OUTER JOIN LATERAL (
  SELECT f.title, SUM(amount) AS revenue
  FROM film AS f
  JOIN film_actor AS fa USING (film_id)
  JOIN inventory AS i USING (film_id)
  JOIN rental AS r USING (inventory_id)
  JOIN payment AS p USING (rental_id)
  WHERE fa.actor_id = a.actor_id -- JOIN predicate with the outer query!
  GROUP BY f.film_id
  ORDER BY revenue DESC
  LIMIT 5
) AS f
ON true

It will find the TOP 5 revenue producing films per actor. Every time you need a TOP-N-per-something query, LATERAL JOIN will be your friend. If you're a SQL Server person, then you know this JOIN type under the name APPLY

SELECT a.first_name, a.last_name, f.*
FROM actor AS a
OUTER APPLY (
  SELECT f.title, SUM(amount) AS revenue
  FROM film AS f
  JOIN film_actor AS fa ON f.film_id = fa.film_id
  JOIN inventory AS i ON f.film_id = i.film_id
  JOIN rental AS r ON i.inventory_id = r.inventory_id
  JOIN payment AS p ON r.rental_id = p.rental_id
  WHERE fa.actor_id = a.actor_id -- JOIN predicate with the outer query!
  GROUP BY f.film_id
  ORDER BY revenue DESC
  LIMIT 5
) AS f

OK, perhaps that's cheating, because a LATERAL JOIN or APPLY expression is really a "correlated subquery" that produces several rows. But if we allow for "correlated subqueries", we can also talk about...

MULTISET

This is only really implemented by Oracle and Informix (to my knowledge), but it can be emulated in PostgreSQL using arrays and/or XML and in SQL Server using XML.

MULTISET produces a correlated subquery and nests the resulting set of rows in the outer query. The below query selects all actors and for each actor collects their films in a nested collection:

SELECT a.*, MULTISET (
  SELECT f.*
  FROM film AS f
  JOIN film_actor AS fa USING (film_id)
  WHERE a.actor_id = fa.actor_id
) AS films
FROM actor

As you have seen, there are more types of JOIN than just the "boring" INNER, OUTER, and CROSS JOIN that are usually mentioned. More details in my article. And please, stop using Venn diagrams to illustrate them.

You can use RawGit:
https://rawgit.com/necolas/css3-social-signin-buttons/master/index.html

It works better (at the time of this writing) than http://htmlpreview.github.com/, serving files with proper Content-Type headers. Additionally, it also provides CDN URL for use in production.

Yes, it is possible and you have answered it! About good practises, I think it is better to launch commands from files and not directly from your code. So you have to make Java execute the list of commands (or one command) in an existing .bat, .sh , .ksh ... files. Here is an example of executing a list of commands in a file MyFile.sh:

    String[] cmd = { "sh", "MyFile.sh", "\pathOfTheFile"};
    Runtime.getRuntime().exec(cmd);

If you want to do a horizontal centering, just put the form inside a DIV tag and apply align="center" attribute to it. So even if the form width is changed, your centering will remain the same.

<div align="center"><form id="form_login"><!--form content here--></form></div>

UPDATE

@G-Cyr is right. align="center" attribute is now obsolete. You can use text-align attribute for this as following.

<div style="text-align:center"><form id="form_login"><!--form content here--></form></div>

This will center all the content inside the parent DIV. An optional way is to use margin: auto CSS attribute with predefined widths and heights. Please follow the following thread for more information.

How to horizontally center a in another ?

Vertical centering is little difficult than that. To do that, you can do the following stuff.

html

<body>
<div id="parent">
    <form id="form_login">
     <!--form content here-->
    </form>
</div>
</body>

Css

#parent {
   display: table;
   width: 100%;
}
#form_login {
   display: table-cell;
   text-align: center;
   vertical-align: middle;
}

In addition, if you are using Tern eclipse IDE or IBM Node.js Tools for Eclipse, you may need to disable JSHint and other libraries that you don't want.

To disable this, Project Properties > Tern > Modules > JSHint or any other library that you don't want.

I've been trying to get my ASP.NET MVC controller to parse some model that i submitted to it using Postman.

I needed the following to get it to work:

• controller action

  [HttpPost]
  [PermitAllUsers]
  [Route("Models")]
  public JsonResult InsertOrUpdateModels(Model entities)
  {
      // ...
      return Json(response, JsonRequestBehavior.AllowGet);
  }
  

• a Models class

  public class Model
  {
      public string Test { get; set; }
      // ...
  }
  

• headers for Postman's request, specifically, Content-Type

  

• json in the request body

  

Since the splitting on commas question is duplicated to this question, adding this here.

If you want to split on a character and also handle extra whitespace that might follow that character, which often happens with commas, you can use replace then split, like this:

var items = string.replace(/,\s+/, ",").split(',')

CREATE TABLE #tmp
(
    sizeId Varchar(MAX)
)

INSERT  #tmp 
    VALUES ('44'),
        ('44,45,46'),
        ('44,45,46'),
        ('44,45,46'),
        ('44,45,46'),
        ('44,45,46'),
        ('44,45,46')


SELECT * FROM #tmp
DECLARE @SqlStr VARCHAR(MAX)

SELECT @SqlStr = STUFF((SELECT ',' + sizeId
              FROM #tmp
              ORDER BY sizeId
              FOR XML PATH('')), 1, 1, '') 


SELECT TOP 1 * FROM (
select items, count(*)AS Occurrence
  FROM dbo.Split(@SqlStr,',')
  group by items
  having count(*) > 1
  )K
  ORDER BY K.Occurrence DESC    

In some OS you need to use new libraries: libmagick++4 libmagick++-dev

You can use:

sudo apt-get install libmagick++4 libmagick++-dev

BEST solution if you ask me is this. This will save the file with the file name of your choice and automatically in HTML or in TXT at your choice with buttons.

Example:

function download(filename, text) {
  var pom = document.createElement('a');
  pom.setAttribute('href', 'data:text/plain;charset=utf-8,' + 

encodeURIComponent(text));
  pom.setAttribute('download', filename);

  pom.style.display = 'none';
  document.body.appendChild(pom);

  pom.click();

  document.body.removeChild(pom);
}

function addTextHTML()
{
    document.addtext.name.value = document.addtext.name.value + ".html"
}

function addTextTXT()
{
    document.addtext.name.value = document.addtext.name.value + ".txt"
}

<html>
  <head></head>
  <body>

    <form name="addtext" onsubmit="download(this['name'].value, this['text'].value)">

    <textarea rows="10" cols="70" name="text" placeholder="Type your text here:"></textarea>
    <br>
    <input type="text" name="name" value="" placeholder="File Name">
    <input type="submit" onClick="addTextHTML();" value="Save As HTML">
    <input type="submit" onClick="addTexttxt();" value="Save As TXT">

    </form>
  </body>
</html>

Going back to absolute basics here. The answers on this page and a little googling have brought me to the following resolution to my issue. Steps to restart the apache service with Xampp installed:-

1. Click the start button and type CMD (if on Windows Vista or later and Apache is installed as a service make sure this is an elevated command prompt)
2. In the command window that appears type cd C:\xampp\apache\bin (the default installation path for Xampp)
3. Then type httpd -k restart

I hope that this is of use to others just starting out with running a local Apache server.

A Web Service if you want is a Web API. Specifically Web API usually means RESTful (HTTP based) web service and Web Service usually means SOAP+WSDL (+HTTP or SMTP or JMS..).

Tipically RESTful web services are opposed to Web Services (WSDL,SOAP) but recently it has been introduced the term RESTful Web services (with uppercase 'W') that means RESTful+WSDL+SOAP..

Hope it helps!

Microsoft says here

Table variables does not have distribution statistics, they will not trigger recompiles. Therefore, in many cases, the optimizer will build a query plan on the assumption that the table variable has no rows. For this reason, you should be cautious about using a table variable if you expect a larger number of rows (greater than 100). Temp tables may be a better solution in this case.

What one program writes to stdout can be read by another via stdin. So simply, using c, write prog1 to print something using printf() and prog2 to read something using scanf(). Then just run

./prog1 | ./prog2

I have found the solution. Just download the following Office update: https://support.microsoft.com/en-us/kb/2920754

Choose between 32-bit or 64-bit and install.

Worked for me, hope it works for you.

After Ctrl+End, you can do the Ctrl+A to select all in the buffer and then paste into Excel. Excel even put each Oracle column into its own column instead of squishing the whole row into one column. Nice..

"12345".each_char.map(&:to_i)

each_char does basically the same as split(''): It splits a string into an array of its characters.

hmmm, I just realize now that in the original question the string contains commas, so my answer is not really helpful ;-(..

You can use string operators:

$ foo=1:2:3:4:5
$ echo ${foo##*:}
5

This trims everything from the front until a ':', greedily.

${foo  <-- from variable foo
  ##   <-- greedy front trim
  *    <-- matches anything
  :    <-- until the last ':'
 }

I was looking for the answer too and my intention was to clean every non-alpha and there shouldn't have more than one space.
So, I modified Alex's answer to this, and this is working for me preg_replace('/[^a-z|\s+]+/i', ' ', $name)
The regex above turned sy8ed sirajul7_islam to sy ed sirajul islam
Explanation: regex will check NOT ANY from a to z in case insensitive way or more than one white spaces, and it will be converted to a single space.

If the object is actually a Boolean instance, then just cast it:

boolean di = (Boolean) someObject;

The explicit cast will do the conversion to Boolean, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:

boolean di = ((Boolean) someObject).booleanValue();

If someObject doesn't refer to a Boolean value though, what do you want the code to do?

For those wondering, @edward-coast

If you want to set the keep alive for the server, add this to /etc/ssh/sshd_config:

ClientAliveInterval 60
ClientAliveCountMax 2

ClientAliveInterval: Sets a timeout interval in seconds after which if no data has been received from the client, sshd(8) will send a message through the encrypted channel to request a response from the client.

ClientAliveCountMax: Sets the number of client alive messages (see below) which may be sent without sshd(8) receiving any messages back from the client. If this threshold is reached while client alive messages are being sent, sshd will disconnect the client, terminating the session.

As it is written before, some folders (/META-INF/resources/, /resources/, /static/, /public/) serve static content by default, conroller misconfiguration can break this behaviour.

It is a common pitfall that people define the base url of a controller in the @RestController annotation, instead of the @RequestMapping annotation on the top of the controllers.

This is wrong:

@RestController("/api/base")
public class MyController {

    @PostMapping
    public String myPostMethod( ...) {

The above example will prevent you from opening the index.html. The Spring expects a POST method at the root, because the myPostMethod is mapped to the "/" path.

You have to use this instead:

@RestController
@RequestMapping("/api/base")
public class MyController {

    @PostMapping
    public String myPostMethod( ...) {

While the answer above is correct I would not recommend you to change the name in order to rely on it in the code.

Names are tricky. They can change. You should use the ShapeId and SlideId.

Especially beware to change the name of a shape programmatically since PowerPoint relies on the name and it might hinder its regular operation.

In Swift 5 , Thanks @Adrian's answer a lot

extension UITableView{

    func hasRowAtIndexPath(indexPath: IndexPath) -> Bool {
        return indexPath.section < numberOfSections && indexPath.row < numberOfRows(inSection: indexPath.section)
    }

    func scrollToTop(_ animated: Bool = false) {
        let indexPath = IndexPath(row: 0, section: 0)
        if hasRowAtIndexPath(indexPath: indexPath) {
            scrollToRow(at: indexPath, at: .top, animated: animated)
        }
    }

}

Usage:

tableView.scrollToTop()

The || and && operators are short circuit, so if the left side of || evaluates to true or the left side of && evaluates to false, the right side will not be evaluated. That's equivalent to a break.

You can write a jQuery function like this to determine if an element is in the viewport.

Include this somewhere after jQuery is included:

$.fn.isInViewport = function() {
    var elementTop = $(this).offset().top;
    var elementBottom = elementTop + $(this).outerHeight();

    var viewportTop = $(window).scrollTop();
    var viewportBottom = viewportTop + $(window).height();

    return elementBottom > viewportTop && elementTop < viewportBottom;
};

Sample usage:

$(window).on('resize scroll', function() {
    if ($('#Something').isInViewport()) {
        // do something
    } else {
        // do something else
    }
});

Note that this only checks the top and bottom positions of elements, it doesn't check if an element is outside of the viewport horizontally.

Make

if [ "$file" == "*.txt" ]

like this:

if [[ $file == *.txt ]]

That is, double brackets and no quotes.

The right side of == is a shell pattern. If you need a regular expression, use =~ then.

as @chepner says in his comment you are comparing $i to a fixed string.

To expand and rectify the situation you should use [[ ]] with the regex operator =~

eg:

for i in $(ls);do
    if [[ $i =~ .*\.java$ ]];then
        echo "I want to do something with the file $i"
    fi
done

the regex to the right of =~ is tested against the value of the left hand operator and should not be quoted, ( quoted will not error but will compare against a fixed string and so will most likely fail"

but @chepner 's answer above using glob is a much more efficient mechanism.

Here's Jeanne's lovely answer, but wrapped in a tidy function for muppets like me:

private static String getUrl(String aUrl) throws MalformedURLException, IOException
{
    String urlData = "";
    URL urlObj = new URL(aUrl);
    URLConnection conn = urlObj.openConnection();
    try (BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(), StandardCharsets.UTF_8))) 
    {
        urlData = reader.lines().collect(Collectors.joining("\n"));
    }
    return urlData;
}

ALL_TAB_COLUMNS should be queryable from PL/SQL. DESC is a SQL*Plus command.

Simple Version

One way is to use the carriage return ('\r') character to return to the start of the line without advancing to the next line.

Python 3

for x in range(10):
    print(x, end='\r')
print()

Python 2.7 forward compatible

from __future__ import print_function
for x in range(10):
    print(x, end='\r')
print()

Python 2.7

for x in range(10):
    print '{}\r'.format(x),
print

Python 2.0-2.6

for x in range(10):
    print '{0}\r'.format(x),
print

In the latter two (Python 2-only) cases, the comma at the end of the print statement tells it not to go to the next line. The last print statement advances to the next line so your prompt won't overwrite your final output.

Line Cleaning

If you can’t guarantee that the new line of text is not shorter than the existing line, then you just need to add a “clear to end of line” escape sequence, '\x1b[1K' ('\x1b' = ESC):

for x in range(75):
    print(‘*’ * (75 - x), x, end='\x1b[1K\r')
print()

This sample code should work:

var http = require('http');
var options = {method: 'HEAD', host: 'stackoverflow.com', port: 80, path: '/'};
var req = http.request(options, function(res) {
    console.log(JSON.stringify(res.headers));
  }
);
req.end();

Lots of ways to do this. The most reliable is find.

Dim rLastCell As Range

Set rLastCell = ws.Cells.Find(What:="*", After:=ws.Cells(1, 1), LookIn:=xlFormulas, LookAt:= _
xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious, MatchCase:=False)

MsgBox ("The last used column is: " & rLastCell.Column)

If you want to find the last column used in a particular row you can use:

Dim lColumn As Long

lColumn = ws.Cells(1, Columns.Count).End(xlToLeft).Column

Using used range (less reliable):

Dim lColumn As Long

lColumn = ws.UsedRange.Columns.Count

Using used range wont work if you have no data in column A. See here for another issue with used range:

See Here regarding resetting used range.

You can solve the problem by checking if your date matches a REGEX pattern. If not, then NULL (or something else you prefer).

In my particular case it was necessary because I have >20 DATE columns saved as CHAR, so I don't know from which column the error is coming from.

Returning to your query:

1. Declare a REGEX pattern.
It is usually a very long string which will certainly pollute your code (you may want to reuse it as well).

define REGEX_DATE = "'your regex pattern goes here'"

Don't forget a single quote inside a double quote around your Regex :-)

A comprehensive thread about Regex date validation you'll find here.

2. Use it as the first CASE condition:

To use Regex validation in the SELECT statement, you cannot use REGEXP_LIKE (it's only valid in WHERE. It took me a long time to understand why my code was not working. So it's certainly worth a note.

Instead, use REGEXP_INSTR
For entries not found in the pattern (your case) use REGEXP_INSTR (variable, pattern) = 0 .

    DEFINE REGEX_DATE = "'your regex pattern goes here'"

    SELECT   c.contract_num,
         CASE
            WHEN REGEXP_INSTR(c.event_dt, &REGEX_DATE) = 0 THEN NULL
            WHEN   (  MAX (TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
                    - MIN (TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
                 / COUNT (c.event_occurrence) < 32
            THEN
              'Monthly'
            WHEN       (  MAX (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
                        - MIN (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
                     / COUNT (c.event_occurrence) >= 32
                 AND   (  MAX (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
                        - MIN (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
                     / COUNT (c.event_occurrence) < 91
            THEN
              'Quarterley'
            ELSE
              'Yearly'
         END

Here's a succinct and generic solution to use a seaborn color palette.

First find a color palette you like and optionally visualize it:

sns.palplot(sns.color_palette("Set2", 8))

Then you can use it with matplotlib doing this:

# Unique category labels: 'D', 'F', 'G', ...
color_labels = df['color'].unique()

# List of RGB triplets
rgb_values = sns.color_palette("Set2", 8)

# Map label to RGB
color_map = dict(zip(color_labels, rgb_values))

# Finally use the mapped values
plt.scatter(df['carat'], df['price'], c=df['color'].map(color_map))

All approaches that test the existence of "lock files" are flawed.

Why? Because there is no way to check whether a file exists and create it in a single atomic action. Because of this; there is a race condition that WILL make your attempts at mutual exclusion break.

Instead, you need to use mkdir. mkdir creates a directory if it doesn't exist yet, and if it does, it sets an exit code. More importantly, it does all this in a single atomic action making it perfect for this scenario.

if ! mkdir /tmp/myscript.lock 2>/dev/null; then
    echo "Myscript is already running." >&2
    exit 1
fi

For all details, see the excellent BashFAQ: http://mywiki.wooledge.org/BashFAQ/045

If you want to take care of stale locks, fuser(1) comes in handy. The only downside here is that the operation takes about a second, so it isn't instant.

Here's a function I wrote once that solves the problem using fuser:

#       mutex file
#
# Open a mutual exclusion lock on the file, unless another process already owns one.
#
# If the file is already locked by another process, the operation fails.
# This function defines a lock on a file as having a file descriptor open to the file.
# This function uses FD 9 to open a lock on the file.  To release the lock, close FD 9:
# exec 9>&-
#
mutex() {
    local file=$1 pid pids 

    exec 9>>"$file"
    { pids=$(fuser -f "$file"); } 2>&- 9>&- 
    for pid in $pids; do
        [[ $pid = $$ ]] && continue

        exec 9>&- 
        return 1 # Locked by a pid.
    done 
}

You can use it in a script like so:

mutex /var/run/myscript.lock || { echo "Already running." >&2; exit 1; }

If you don't care about portability (these solutions should work on pretty much any UNIX box), Linux' fuser(1) offers some additional options and there is also flock(1).

Try using pytds, it works throughout more complexity environment than pyodbc and more easier to setup.

I made it work on Ubuntu 18.04

Ref: https://github.com/denisenkom/pytds

Example code in documentation:

import pytds
with pytds.connect('server', 'database', 'user', 'password') as conn:
    with conn.cursor() as cur:
        cur.execute("select 1")
        cur.fetchall()

You can use COALESCE in conjunction with NULLIF for a short, efficient solution:

COALESCE( NULLIF(yourField,'') , '0' )

The NULLIF function will return null if yourField is equal to the second value ('' in the example), making the COALESCE function fully working on all cases:

                 QUERY                     |                RESULT 
---------------------------------------------------------------------------------
SELECT COALESCE(NULLIF(null  ,''),'0')     |                 '0'
SELECT COALESCE(NULLIF(''    ,''),'0')     |                 '0'
SELECT COALESCE(NULLIF('foo' ,''),'0')     |                 'foo'

Note that if you are getting this error instead:

fatal: could not read Username for 'https://github.com': No error

Then you need to update your Git to version 2.16 or later.

You need to get the HLS m3u8 playlist files from the video's manifest. There are ways to do this by hand, but for simplicity I'll be using the youtube-dl tool to get this information. I'll be using this live stream as an example: https://www.youtube.com/watch?v=_Gtc-GtLlTk

In this case, there are two videos because the live stream contains two cameras. From here, we need to get the HLS URL for a specific stream. Use -f to pass in the format you would like to watch, and -g to get that stream's URL:

These are your HLS m3u8 playlists, one for each camera associated with the live stream.

Without youtube-dl, your flow might look like this:

In a new PHP7 there is a finally a support for a cryptographically secure pseudo-random integers.

int random_int ( int $min , int $max )

random_int — Generates cryptographically secure pseudo-random integers

which basically makes previous answers obsolete.

Here is a function using recursion which will work on any arbitrary nested list.

if you want to be able to convert integer back to corresponding enum with selected value see Constants.forValue(...) in below auto generated code but if not the answer of BlairHippo is best way to do it.

public enum Constants

SIGN_CREATE(0),
SIGN_CREATE(1),
HOME_SCREEN(2),
REGISTER_SCREEN(3);

    public static final int SIZE = java.lang.Integer.SIZE;

    private int intValue;

    private static java.util.HashMap<Integer, Constants> getMappings()
    {
        if (mappings == null)
        {
            synchronized (Constants.class)
            {
                if (mappings == null)
                {
                    mappings = new java.util.HashMap<Integer, Constants>();
                }
            }
        }
        return mappings;
    }

    private Constants(int value)
    {
        intValue = value;
        getMappings().put(value, this);
    }

    public int getValue()
    {

    }

    public static Constants forValue(int value)

An Open Source alternative is Nominatim from Open Street Map. All you have to do is set the variables in an URL and it returns the city/country of that location. Please check the following link for official documentation: Nominatim

If this is for testing and/or development purposes, setuptools has a develop command that updates every time you make a change (so you don't have to uninstall and reinstall every time you make a change). And you can uninstall the package using this command as well.

If you do use this, anything that you declare as a script will be left behind as a lingering file.

Frankly, this looks like a semantic distinction, not a technical distinction. The phrase Data Access Object doesn't refer to a "database" at all. And, although you could design it to be database-centric, I think most people would consider doing so a design flaw.

The purpose of the DAO is to hide the implementation details of the data access mechanism. How is the Repository pattern different? As far as I can tell, it isn't. Saying a Repository is different to a DAO because you're dealing with/return a collection of objects can't be right; DAOs can also return collections of objects.

Everything I've read about the repository pattern seems rely on this distinction: bad DAO design vs good DAO design (aka repository design pattern).

You can use the INSERT ... SELECT statement to get the MAX()+1 value and insert at the same time:

INSERT INTO 
customers( customer_id, firstname, surname )
SELECT MAX( customer_id ) + 1, 'jim', 'sock' FROM customers;

^{Note: You need to drop the VALUES from your INSERT and make sure the SELECT selected fields match the INSERT declared fields.}

You need to do some escaping I think.

find /home/me/download/ -type f -name "*.rm" -exec ffmpeg -i {} \-sameq {}.mp3 \&\& rm {}\;

Change to older Visual Studio. Weird solution that worked for me. I was using Visual studio 2017, after changing to Visual Studio 2015 ,everything worked.

For python 3.3

from datetime import datetime, timedelta
futuredate = datetime.now() + timedelta(days=10)

<ScrollViewer MaxHeight="50"  
              Width="Auto" 
              HorizontalScrollBarVisibility="Disabled"
              VerticalScrollBarVisibility="Auto">
     <TextBlock Text="{Binding Path=}" 
                Style="{StaticResource TextStyle_Data}" 
                TextWrapping="Wrap" />
</ScrollViewer>

I am doing this in another way by putting MaxHeight in ScrollViewer.

Just Adjust the MaxHeight to show more or fewer lines of text. Easy.

a = [5, 1, 6, 14, 2, 8]
b = [2, 6, 15]

a - b
# => [5, 1, 14, 8]

b - a
# => [15]

(b - a).empty?
# => false

You could use a regular express to remove everything apart from those characters you wish to keep:

$string=preg_replace('/[^A-Za-z0-9 _\-\+\&]/','',$string);

Replaces everything that is not (^) the letters A-Z or a-z, the numbers 0-9, space, underscore, hypen, plus and ampersand - with nothing (i.e. remove it).

Here is an example from my HOW TO Matlab page:

close all; clear all;

img   = imread('lena.tif','tif');
imagesc(img)
img   = fftshift(img(:,:,2));
F     = fft2(img);

figure;

imagesc(100*log(1+abs(fftshift(F)))); colormap(gray); 
title('magnitude spectrum');

figure;
imagesc(angle(F));  colormap(gray);
title('phase spectrum');

This gives the magnitude spectrum and phase spectrum of the image. I used a color image, but you can easily adjust it to use gray image as well.

ps. I just noticed that on Matlab 2012a the above image is no longer included. So, just replace the first line above with say

img = imread('ngc6543a.jpg');

and it will work. I used an older version of Matlab to make the above example and just copied it here.

On the scaling factor

When we plot the 2D Fourier transform magnitude, we need to scale the pixel values using log transform to expand the range of the dark pixels into the bright region so we can better see the transform. We use a c value in the equation

s = c log(1+r) 

There is no known way to pre detrmine this scale that I know. Just need to try different values to get on you like. I used 100 in the above example.

try this

             <a tabindex=9 href="www.demo9.com">link</a>    
             <a tabindex=10 href="www.demo10.com">link</a>   
        </div>

</body>

<script>
$(document).ready(function(){
  $(".linkCollection a").focus(function(){
    var href=$(this).attr('href');
    console.log(href);
    // href variable holds the active selected link.
  });
});
</script>

don't forgot to add jQuery library

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>

You'll have to have a ContextLoaderListener in your web.xml - It loads your configuration files.

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

You need to understand the difference between Web application context and root application context .

In the web MVC framework, each DispatcherServlet has its own WebApplicationContext, which inherits all the beans already defined in the root WebApplicationContext. These inherited beans defined can be overridden in the servlet-specific scope, and new scope-specific beans can be defined local to a given servlet instance.

The dispatcher servlet's application context is a web application context which is only applicable for the Web classes . You cannot use these for your middle tier layers . These need a global app context using ContextLoaderListener .

Read the spring reference here for spring mvc .

Aggregating with $lookup and subsequent $group is pretty cumbersome, so if (and that's a medium if) you're using node & Mongoose or a supporting library with some hints in the schema, you could use a .populate() to fetch those documents:

var mongoose = require("mongoose"),
    Schema = mongoose.Schema;

var productSchema = Schema({ ... });

var orderSchema = Schema({
  _id     : Number,
  products: [ { type: Schema.Types.ObjectId, ref: "Product" } ]
});

var Product = mongoose.model("Product", productSchema);
var Order   = mongoose.model("Order", orderSchema);

...

Order
    .find(...)
    .populate("products")
    ...

Since I haven't seen it in the answers above, I thought I would add my simple workaround, which is just to add a global_dict argument to the function requiring the calling module's globals, and then pass the dict into the function when calling; e.g:

# external_module
def imported_function(global_dict=None):
    print(global_dict["a"])


# calling_module
a = 12
from external_module import imported_function
imported_function(global_dict=globals())

>>> 12
