Just to complete this topic: If you set up your table with primary key and auto increment you can omit the process of manually incrementing the id.

Check out this example

if (!$CI->db->table_exists(db_prefix() . 'my_table_name')) {
    $CI->db->query('CREATE TABLE `' . db_prefix() . "my_table_name` (
  `serviceid` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
  `name` varchar(64) NOT NULL,
  `hash` varchar(32) NOT NULL,
  `url` varchar(120) NOT NULL,
  `datecreated` datetime NOT NULL,
  `active` tinyint(1) NOT NULL DEFAULT '1'
) ENGINE=InnoDB DEFAULT CHARSET=" . $CI->db->char_set . ';');

Now you can insert rows

$this->db->insert(db_prefix(). 'my_table_name', [
            'name'         => $data['name'],
            'hash'            => app_generate_hash(),
            'url'     => $data['url'],
            'datecreated'     => date('Y-m-d H:i:s'),
            'active'          => $data['active']
        ]);

Here is a way.

We set-up options' string, in a list, just as we set-up command line arguments. In this case opts=['-g', 'videoID']. Then, invoke youtube_dl.main(opts). In this way, we write our custom .py module, import youtube_dl and then invoke the main() function.

The idea is that the response body gives you a page that links you to the thing:

201 Created

The 201 (Created) status code indicates that the request has been fulfilled and has resulted in one or more new resources being created. The primary resource created by the request is identified by either a Location header field in the response or, if no Location field is received, by the effective request URI.

This means that you would include a Location in the response header that gives the URL of where you can find the newly created thing:

HTTP/1.1 201 Created
Date: Sat, 02 Apr 2016 12:22:40 GMT
Location: http://stackoverflow.com/a/36373586/12597

Response body

They then go on to mention what you should include in the response body:

The 201 response payload typically describes and links to the resource(s) created.

For the human using the browser, you give them something they can look at, and click, to get to their newly created resource:

If the page will only be used by a robot, the it makes sense to have the response be computer readable:

      <resource>http://stackoverflow.com/a/1962757/12597</resource>
   </additional>
</createdResource>

Or, if you prefer:

HTTP/1.1 201 Created
Date: Sat, 02 Apr 2016 12:22:40 GMT
Location: http://stackoverflow.com/a/36373586/12597

   "additional": [

      "http://stackoverflow.com/a/36373586/12597"
   ]
}

The response is entirely up to you; it's arbitrarily what you'd like.

Cache friendly

Finally there's the optimization that I can pre-cache the created resource (because I already have the content; I just uploaded it). The server can return a date or ETag which I can store with the content I just uploaded:

See Section 7.2 for a discussion of the meaning and purpose of validator header fields, such as ETag and Last-Modified, in a 201 response.

And ETag s are purely arbitrary values. Having them be different when a resource changes (and caches need to be updated) is all that matters. The ETag is usually a hash (e.g. SHA2). But it can be a database rowversion, or an incrementing revision number. Anything that will change when the thing changes.

Update, as commented by VonC in How to remove old Docker containers.

With Docker 1.13 (Q4 2016), you now have:

docker system prune will delete ALL unused data (i.e., in order: containers stopped, volumes without containers and images with no containers).

See PR 26108 and commit 86de7c0, which are introducing a few new commands to help facilitate visualizing how much space the Docker daemon data is taking on disk and allowing for easily cleaning up "unneeded" excess.

docker system prune

WARNING! This will remove:
    - all stopped containers
    - all volumes not used by at least one container
    - all images without at least one container associated to them

In Windows 8 and up there's a way to enable the feature from the command line without having to download/install anything explicitly by running the following:

dism /online /Enable-Feature:Windows-Identity-Foundation

And then find the file by running the following at the root of your Windows disk:

dir /s /b Microsoft.IdentityModel.dll

There is an option in search => file and shortcut is Ctrl+H. Go for further refer follow link. This is work fine with Eclipse Neon

Is there a way to find/replace across an entire project in Eclipse?

this worked for me:

$data=DB::table('table_name')->select(.......)->get();
$data=array_map(function($item){
    return (array) $item;
},$data);

or

$data=array_map(function($item){
    return (array) $item;
},DB::table('table_name')->select(.......)->get());

For completeness sake, since Ruby 1.9 String#chr returns the first character of a string. Its still available in 2.0 and 2.1.

"Smith".chr    #=> "S"

Here's pure javascript example of handling classes during scrolling.

You'd probably want to throttle handling scroll events, more so as handler logic gets more complex, in that case throttle from lodash lib comes in handy.

And if you're doing spa, keep in mind that you need to clear event listeners with removeEventListener once they're not needed (eg during onDestroy lifecycle hook of your component, like destroyed() for Vue, or maybe return function of useEffect hook for React).

const navbar = document.getElementById('navbar')_x000D_
_x000D_
// OnScroll event handler_x000D_
const onScroll = () => {_x000D_
_x000D_
  // Get scroll value_x000D_
  const scroll = document.documentElement.scrollTop_x000D_
_x000D_
  // If scroll value is more than 0 - add class_x000D_
  if (scroll > 0) {_x000D_
    navbar.classList.add("scrolled");_x000D_
  } else {_x000D_
    navbar.classList.remove("scrolled")_x000D_
  }_x000D_
}_x000D_
_x000D_
// Optional - throttling onScroll handler at 100ms with lodash_x000D_
const throttledOnScroll = _.throttle(onScroll, 100, {})_x000D_
_x000D_
// Use either onScroll or throttledOnScroll_x000D_
window.addEventListener('scroll', onScroll)

#navbar {_x000D_
  position: fixed;_x000D_
  top: 0;_x000D_

rciovati's answer is entirely correct I just wanted to add one more tidbit that you can also create variables for every build type within the default config portion of your build.gradle. This would look like this:

android {
    defaultConfig {
        buildConfigField "String", "APP_NAME", "\"APP_NAME\""
    }
}

This will allow you to have access to through

BuildConfig.App_NAME

Just wanted to make a note of this scenario as well if you want a common config.

Update to MySQL 8.0.16 to use checks:

As of MySQL 8.0.16, CREATE TABLE permits the core features of table and column CHECK constraints, for all storage engines. CREATE TABLE permits the following CHECK constraint syntax, for both table constraints and column constraints

MySQL Checks Documentation

This functionality can also be added using JavaScript. Carto.net has an example:

http://old.carto.net/papers/svg/textFlow/

Something else that also might be useful to are you are editable text areas:

The Perl documentation comes with a nice collection of FAQs. Your question is frequently asked:

% perldoc -q duplicate

The answer, copy and pasted from the output of the command above, appears below:

 How can I remove duplicate elements from a list or array?
   (contributed by brian d foy)

   Use a hash. When you think the words "unique" or "duplicated", think
   "hash keys".

   If you don't care about the order of the elements, you could just
   create the hash then extract the keys. It's not important how you
   create that hash: just that you use "keys" to get the unique elements.

       my %hash   = map { $_, 1 } @array;
       # or a hash slice: @hash{ @array } = ();
       # or a foreach: $hash{$_} = 1 foreach ( @array );

       my @unique = keys %hash;

   If you want to use a module, try the "uniq" function from
   "List::MoreUtils". In list context it returns the unique elements,
   preserving their order in the list. In scalar context, it returns the
   number of unique elements.

       use List::MoreUtils qw(uniq);

       my @unique = uniq( 1, 2, 3, 4, 4, 5, 6, 5, 7 ); # 1,2,3,4,5,6,7
       my $unique = uniq( 1, 2, 3, 4, 4, 5, 6, 5, 7 ); # 7

   You can also go through each element and skip the ones you've seen
   before. Use a hash to keep track. The first time the loop sees an
   element, that element has no key in %Seen. The "next" statement creates
   the key and immediately uses its value, which is "undef", so the loop
   continues to the "push" and increments the value for that key. The next
   time the loop sees that same element, its key exists in the hash and
   the value for that key is true (since it's not 0 or "undef"), so the
   next skips that iteration and the loop goes to the next element.

       my @unique = ();
       my %seen   = ();

       foreach my $elem ( @array )
       {
         next if $seen{ $elem }++;
         push @unique, $elem;
       }

   You can write this more briefly using a grep, which does the same
   thing.

       my %seen = ();
       my @unique = grep { ! $seen{ $_ }++ } @array;

Actually you're close to your goal, you just need to use nodes() method to split your rows and then get values:

select
    s.SqmId,
    m.c.value('@id', 'varchar(max)') as id,
    m.c.value('@type', 'varchar(max)') as type,
    m.c.value('@unit', 'varchar(max)') as unit,
    m.c.value('@sum', 'varchar(max)') as [sum],
    m.c.value('@count', 'varchar(max)') as [count],
    m.c.value('@minValue', 'varchar(max)') as minValue,
    m.c.value('@maxValue', 'varchar(max)') as maxValue,
    m.c.value('.', 'nvarchar(max)') as Value,
    m.c.value('(text())[1]', 'nvarchar(max)') as Value2
from sqm as s
    outer apply s.data.nodes('Sqm/Metrics/Metric') as m(c)

I'm not sure I agree with inheritance from ValueError -- my interpretation of the documentation is that ValueError is only supposed to be raised by builtins... inheriting from it or raising it yourself seems incorrect.

Raised when a built-in operation or function receives an argument that has the right type but an inappropriate value, and the situation is not described by a more precise exception such as IndexError.

Check out Reuxables although it comes at a cost.

I checked the answer however, (for each) in PHP is deprecated and no longer work with the latest php versions.

Usually we would convert an array into a string to log it somewhere, perhaps debugging or test etc.

I would convert the array into a string by doing:

$Output = implode(",", $SourceArray);

Whereas:

$output is the result (where the string would be generated

",": is the separator (between each array field

$SourceArray: is your source array.

I hope this helps

I faced this problem on CentOS.

First I try this

sudo service mysql restart

Then error shows up

Redirecting to /bin/systemctl restart mysql.service
Failed to restart mysql.service: Unit not found.

Then I Found this

Command this solve my problem

systemctl start mariadb.service

if using windows, try with cmd , for me it works. check if docker is started.

Well try ini_set('memory_limit', '256M');

134217728 bytes = 128 MB

Or rewrite the code to consume less memory.

As of September 2017,
1. Click on your project.
2. Select setting on the top most corner.
3. Scroll down the page and click on expand in front of advance setting.
4. Scroll down the page and click on the Remove Project button.
5. Type your project name in text box and click on confirm.

For Perfect DateTime Match in SQL Server

SELECT ID FROM [Table Name] WHERE (DateLog between '2017-02-16 **00:00:00.000**' and '2017-12-16 **23:59:00.999**') ORDER BY DateLog DESC

Today we use Bearer token more often that Basic Authentication but if you want to have Basic Authentication first to get Bearer token then there is a couple ways:

const request = new XMLHttpRequest();
request.open('GET', url, false, username,password)
request.onreadystatechange = function() {
        // D some business logics here if you receive return
   if(request.readyState === 4 && request.status === 200) {
       console.log(request.responseText);
   }
}
request.send()

Full syntax is here

Second Approach using Ajax:

$.ajax
({
  type: "GET",
  url: "abc.xyz",
  dataType: 'json',
  async: false,
  username: "username",
  password: "password",
  data: '{ "key":"sample" }',
  success: function (){
    alert('Thanks for your up vote!');
  }
});

Hopefully, this provides you a hint where to start API calls with JS. In Frameworks like Angular, React, etc there are more powerful ways to make API call with Basic Authentication or Oauth Authentication. Just explore it.

I realize this is an old question and referring to TOAD but if you need to code around this using c# you can split up the list through a for loop. You can essentially do the same with Java using subList();

    List<Address> allAddresses = GetAllAddresses();
    List<Employee> employees = GetAllEmployees(); // count > 1000

    List<Address> addresses = new List<Address>();

    for (int i = 0; i < employees.Count; i += 1000)
    {
        int count = ((employees.Count - i) < 1000) ? (employees.Count - i) - 1 : 1000;
        var query = (from address in allAddresses
                     where employees.GetRange(i, count).Contains(address.EmployeeId)
                     && address.State == "UT"
                     select address).ToList();

        addresses.AddRange(query);
    }

Hope this helps someone.

Microsoft Docs gives us two approaches.

Recommended HttpPost Edit code: Read and update

This is the same old way we used to do in previous versions of Entity Framework. and this is what Microsoft recommends for us.

Advantages

• Prevents overposting
• EFs automatic change tracking sets the Modified flag on the fields that are changed by form input.

Alternative HttpPost Edit code: Create and attach

an alternative is to attach an entity created by the model binder to the EF context and mark it as modified.

As mentioned in the other answer the read-first approach requires an extra database read, and can result in more complex code for handling concurrency conflicts.

What happens when you set all of the attributes in one attr() command like so

$(this).attr({
               id : this.id + '_' + new_id,
               name: this.name + '_' + new_id,
               value: 'test' 
             });

This problem happened to me when I added a picker view and then removed it. In case it will help someone, here's how I solved it finally:

1. Open Document Outline at XCODE (don't know what is Document Outline? I didn't also - google it.. :) ).

2. Find the Scene that makes the warning message appear, in the document outline window.

3. On the problematic scene, stand (click) on View, and then in the Utility (google it) window select the Identity inspector tab and change back the custom class name to default UIView.

That't it. :)

I had the same issue, but I needed to display multiple lines (where text-overflow: ellipsis; fails). I solve it using a textarea inside a TD and then style it to behave like a table cell.

    textarea {
        margin: 0;
        padding: 0;
        width: 100%;
        border: none;
        resize: none;

        /* Remove blinking cursor (text caret) */
        color: transparent;
        display: inline-block;
        text-shadow: 0 0 0 black; /* text color is set to transparent so use text shadow to draw the text */
        &:focus {
            outline: none;
        }
    }

You can also do this using plain JavaScript:

function isRendered(domObj) {
    if ((domObj.nodeType != 1) || (domObj == document.body)) {
        return true;
    }
    if (domObj.currentStyle && domObj.currentStyle["display"] != "none" && domObj.currentStyle["visibility"] != "hidden") {
        return isRendered(domObj.parentNode);
    } else if (window.getComputedStyle) {
        var cs = document.defaultView.getComputedStyle(domObj, null);
        if (cs.getPropertyValue("display") != "none" && cs.getPropertyValue("visibility") != "hidden") {
            return isRendered(domObj.parentNode);
        }
    }
    return false;
}

Notes:

1. Works everywhere

2. Works for nested elements

3. Works for CSS and inline styles

4. Doesn't require a framework

With respect to the all the other answers, here's the screenshot to help someone.

1. Go to https://developers.facebook.com/

2. Click on the Apps menu on the top bar.

3. Select the respective app from the drop down.

The circle next to your app name is not fully green. When you hover mouse on it, you'll see a popup saying, "Not available to all users because your app is not live."

So next, you've to make it publicly available.

4. Click on setting at left panel. [see the screenshot below]

5. In Basic tab add your "Contact Email" (a valid email address - I've added the one which I'm using with developers.facebook.com) and make "Save changes".

6. Next click "App Review" at left panel. [see the screenshot below]

7. Look for this, Do you want to make this app and all its live features available to the general public? and Turn ON the switch next to this.

8. That's it! - App is now publicly available. See the fully green circle next to the app name.

mongod wasn't working to start the daemon for me but after I ran the following, it started working:

Yes, this is a current issue in Chrome. There is an issue report here.

The fix will appear in 40.x.y.z versions.

Until then? I don't think you can resolve the issue yourself. But you can ignore it. The shown error is only related to the dev tools and does not influence the behavior of your website. If you have any other problems they are not related to this error.

You could use a variable to make the calculation and use toFixed when you set the #diskamountUnit element value:

var amount = $("#disk").slider("value") * 1.60;
$("#diskamountUnit").val('$' + amount.toFixed(2));

You can also do that in one step, in the val method call but IMO the first way is more readable:

$("#diskamountUnit").val('$' + ($("#disk").slider("value") * 1.60).toFixed(2));

Try this one...

HTML Code

<form class="submit">
    <input type="text" name="text1"/>
    <input type="text" name="text2"/>
    <input type="submit" name="Submit" value="submit"/>
</form>

jQuery Code

$(function(){
    $('.submit').on('submit', function(event){
        event.preventDefault();
        alert("Form Submission stopped.");
    });
});

or

$(function(){
    $('.submit').on('submit', function(event){
       event.preventDefault();
       event.stopPropagation();
       alert("Form Submission prevented / stopped.");
    });
});

In Xcode 6+ and iOS8+ you can do the simple steps below

1. Paste .app file on desktop.

2. Open terminal and paste the commands below:

   cd desktop

   xcrun simctl install booted xyz.app

3. Open iPhone simulator and click on app and use

For versions below iOS 8, do the following simple steps.

Note: You'll want to make sure that your app is built for all architectures, the Simulator is x386 in the Build Settings and Build Active Architecture Only set to No.

1. Path: Library->Application Support->iPhone Simulator->7.1 (or another version if you need it)->Applications
2. Create a new folder with the name of the app
3. Go inside the folder and place the .app file here.

Assuming your page is available under "http://example.com"

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

Select element by id:

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

Now you can simulate hitting ENTER:

inputElement.send_keys(Keys.ENTER)

or if it is a form you can submit:

inputElement.submit() 

This help me:

If you have a parent container with vertical padding and you want something (e.g. an image) inside that container to ignore its vertical padding you can set a negative, but equal, margin for both 'top' and 'bottom':

margin-top: -100px;
margin-bottom: -100px;

The actual value doesn't appear to matter much. Haven't tried this for horizontal paddings.

Downgrading the JRE from 7 to 6 fixed this issue for me.

Here is a part of my code that parse JSON, it may be helpful for you:

import { Component, Input } from '@angular/core';
import { Injectable }     from '@angular/core';
import { Http, Response, Headers, RequestOptions } from '@angular/http';
import {Observable} from 'rxjs/Rx';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';

@Injectable()
export class AppServices{

    constructor(private http: Http) {
         var obj;
         this.getJSON().subscribe(data => obj=data, error => console.log(error));
    }

    public getJSON(): Observable<any> {
         return this.http.get("./file.json")
                         .map((res:any) => res.json())
                         .catch((error:any) => console.log(error));

     }
}

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

@EvilDr You can create an IUSR_[identifier] account within your AD environment and let the particular application pool run under that IUSR_[identifier] account:

"Application pool" > "Advanced Settings" > "Identity" > "Custom account"

Set your website to "Applicaton user (pass-through authentication)" and not "Specific user", in the Advanced Settings.

Now give that IUSR_[identifier] the appropriate NTFS permissions on files and folders, for example: modify on companydata.

This is not a system font. this font is not supported in other systems. you can use font-face, convert font from this Site or from this

When installing Python 3.4 the "Add python.exe to Path" came up unselected. Re-installed with this selected and problem resolved.

My solution:

File jarToAdd = new File("/path/to/file");

new URLClassLoader(((URLClassLoader) ClassLoader.getSystemClassLoader()).getURLs()) {
    @Override
    public void addURL(URL url) {
         super.addURL(url);
    }
}.addURL(jarToAdd.toURI().toURL());

The problem is that when you add a parameter to DOMDocument::saveHTML() function, you lose the encoding. In a few cases, you'll need to avoid the use of the parameter and use old string function to find what your are looking for.

I think the previous answer works for you, but since this workaround didn't work for me, I'm adding that answer to help people who may be in my case.

If you want tbody to show a scrollbar, set its display: block;.

Set display: table; for the tr so that it keeps the behavior of a table.

To evenly spread the cells, use table-layout: fixed;.

DEMO

CSS:

table, tr td {
    border: 1px solid red
}
tbody {
    display: block;
    height: 50px;
    overflow: auto;
}
thead, tbody tr {
    display: table;
    width: 100%;
    table-layout: fixed;/* even columns width , fix width of table too*/
}
thead {
    width: calc( 100% - 1em )/* scrollbar is average 1em/16px width, remove it from thead width */
}
table {
    width: 400px;
}

If tbody doesn't show a scroll, because content is less than height or max-height, set the scroll any time with: overflow-y: scroll;. DEMO 2

Important note: this approach to making a table scrollable has drawbacks in some cases. (See comments below.)

"2.7.0_bf4fda703454".split("_") gives a list of strings:

In [1]: "2.7.0_bf4fda703454".split("_")
Out[1]: ['2.7.0', 'bf4fda703454']

This splits the string at every underscore. If you want it to stop after the first split, use "2.7.0_bf4fda703454".split("_", 1).

If you know for a fact that the string contains an underscore, you can even unpack the LHS and RHS into separate variables:

In [8]: lhs, rhs = "2.7.0_bf4fda703454".split("_", 1)

In [9]: lhs
Out[9]: '2.7.0'

In [10]: rhs
Out[10]: 'bf4fda703454'

An alternative is to use partition(). The usage is similar to the last example, except that it returns three components instead of two. The principal advantage is that this method doesn't fail if the string doesn't contain the separator.

For Developer certificate, you need to create a developer .mobileprovision profile and install add it to your XCode. In case you want to distribute the app using an adhoc distribution profile you will require AdHoc Distribution certificate and private key installed in your keychain.

If you have not created the cert, here are steps to create it. Incase it has already been created by someone in your team, ask him to share the cert and private key. If that someone is no longer in your team then you can revoke the cert from developer account and create new.

This is the implementation without using any Collection and with complexity order of n. Although the accepted solution is good enough and does not use Collection as well but it seems, it is not taking care of special characters.

import java.util.Arrays;

public class DuplicateCharactersInString {
    public static void main(String[] args) {
        String string = "check duplicate charcters in string";
        string = string.toLowerCase();
        char[] charAr = string.toCharArray();
        Arrays.sort(charAr);
        for (int i = 1; i < charAr.length;) {
            int count = recursiveMethod(charAr, i, 1);
            if (count > 1) {
                System.out.println("'" + charAr[i] + "' comes " + count + " times");
                i = i + count;
            } else
                i++;
        }
    }

    public static int recursiveMethod(char[] charAr, int i, int count) {
        if (ifEquals(charAr[i - 1], charAr[i])) {
            count = count + recursiveMethod(charAr, ++i, count);
        }
        return count;
    }

    public static boolean ifEquals(char a, char b) {
        return a == b;
    }
}

Output :

' ' comes 4 times
'a' comes 2 times
'c' comes 5 times
'e' comes 3 times
'h' comes 2 times
'i' comes 3 times
'n' comes 2 times
'r' comes 3 times
's' comes 2 times
't' comes 3 times

So, "findOneAndUpdate" requires an option to return original document. And, the option is:

MongoDB shell

{returnNewDocument: true}

Ref: https://docs.mongodb.com/manual/reference/method/db.collection.findOneAndUpdate/

Mongoose

{new: true}

Ref: http://mongoosejs.com/docs/api.html#query_Query-findOneAndUpdate

Node.js MongoDB Driver API:

I know there is an accepted answer but I recommend

Simple REST Client Extension for Chrome.

example:

Instead of writing the code from the scratch you can use jquery plug in. Such plug in can provide many configuration option as well.

Here is the one I most liked.

You can use numpy.recfromcsv(filename): the types of each column will be automatically determined (as if you use np.genfromtxt() with dtype=None), and by default delimiter=",". It's basically a shortcut for np.genfromtxt(filename, delimiter=",", dtype=None) that Pierre GM pointed at in his answer.

The following would be enough

String.prototype.boolean = function() {
    return "true" == this; 
};

"true".boolean() // returns true "false".boolean() // returns false

Remove those char * ret declarations inside if blocks which hide outer ret. Therefor you have memory leak and on the other hand un-allocated memory for ret.

To compare a c-style string you should use strcmp(array,"") not array!="". Your final code should looks like below:

char* appendCharToCharArray(char* array, char a)
{
    size_t len = strlen(array);

    char* ret = new char[len+2];

    strcpy(ret, array);    
    ret[len] = a;
    ret[len+1] = '\0';

    return ret;
}

Note that, you must handle the allocated memory of returned ret somewhere by delete[] it.

Why you don't use std::string? it has .append method to append a character at the end of a string:

std::string str;

str.append('x');
// or
str += x;

One advantage is that you are compiling access into the application, so it cannot accidentally be changed by someone modifying the Web.config.

This may not be an advantage to you, and might be a disadvantage. But for some kinds of access, it may be preferrable.

Plus, I find that authorization information in the Web.config pollutes it, and makes it harder to find things. So in some ways its preference, in others there is no other way to do it.

There's a oneliner for this one.

You can simply run,

docker run -v /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war:/usr/local/tomcat/webapps/myapp.war -it -p 8080:8080 tomcat

This will copy the war file to webapps directory and get your app running in no time.

when you manually open the IP address (via the RUN command or mapping a network drive), your PC will send your credentials over the pipe and the file server will receive authorization from the DC.

When ASP.Net tries, then it is going to try to use the IIS worker user (unless impersonation is turned on which will list a few other issues). Traditionally, the IIS worker user does not have authorization to work across servers (or even in other folders on the web server).

// Store the formatted string in 'result'
String result = String.format("%4d", i * j);

// Write the result to standard output
System.out.println( result );

See format and its syntax

Type casting to integer may create problem but even long type can not hold every bit of double after narrowing down to decimal places. If you know your values will never exceed Long.MAX_VALUE value, this might be a clean solution.

So use the following with the above known risk.

double mValue = 1234567890.123456;
long mStrippedValue = new Double(mValue).longValue();

.row {
    margin-right: 15px;
}

throw this in your CSS

Please check whether the Default value for the column id in particular table.if not make it as default

Common Answer: itoa()

This is bad. itoa is non-standard, as pointed out here.

Mid(strYourString, 4) (i.e. without the optional length argument) will return the substring starting from the 4th character and going to the end of the string.

Here's a vectorized approach (assuming the dataframe, data_set to be defined as df instead) that returns a list of tuples as shown:

>>> df.set_index(['data_date'])[['data_1', 'data_2']].to_records().tolist()

produces:

[(datetime.datetime(2012, 2, 17, 0, 0), 24.75, 25.03),
 (datetime.datetime(2012, 2, 16, 0, 0), 25.0, 25.07),
 (datetime.datetime(2012, 2, 15, 0, 0), 24.99, 25.15),
 (datetime.datetime(2012, 2, 14, 0, 0), 24.68, 25.05),
 (datetime.datetime(2012, 2, 13, 0, 0), 24.62, 24.77),
 (datetime.datetime(2012, 2, 10, 0, 0), 24.38, 24.61)]

The idea of setting datetime column as the index axis is to aid in the conversion of the Timestamp value to it's corresponding datetime.datetime format equivalent by making use of the convert_datetime64 argument in DF.to_records which does so for a DateTimeIndex dataframe.

This returns a recarray which could be then made to return a list using .tolist

More generalized solution depending on the use case would be:

df.to_records().tolist()                              # Supply index=False to exclude index

I didn't see any answers that show users where we can find a Global Temp table. You can view Local and Global temp tables in the same location when navigating within SSMS. Screenshot below taken from this link.

Imageio is a Python library that provides an easy interface to read and write a wide range of image data, including animated images, video, volumetric data, and scientific formats. It is cross-platform, runs on Python 2.7 and 3.4+, and is easy to install.

This is example for grayscale image:

import numpy as np
import imageio

# data is numpy array with grayscale value for each pixel.
data = np.array([70,80,82,72,58,58,60,63,54,58,60,48,89,115,121,119])

# 16 pixels can be converted into square of 4x4 or 2x8 or 8x2
data = data.reshape((4, 4)).astype('uint8')

# save image
imageio.imwrite('pic.jpg', data)

A different case in which I encountered this was when I was using echo to pipe the JSON into my python script and carelessly wrapped the JSON string in double quotes:

echo "{"thumbnailWidth": 640}" | myscript.py

Note that the JSON string itself has quotes and I should have done:

echo '{"thumbnailWidth": 640}' | myscript.py

As it was, this is what the python script received: {thumbnailWidth: 640}; the double quotes were effectively stripped.

Specifying the base path in the [Route] attribute and then adding to the base path in the [HttpGet] worked for me. You can try:

    [Route("api/TestApi")]      //this will be the base path
    public class TestController : ApiController
    {
        [HttpGet]  //example call: 'api/TestApi'
        public string Get()
        {
            return string.Empty;
        }
    
        [HttpGet("{id}")]  //example call: 'api/TestApi/4'
        public string GetById(int id) //method name won't matter
        {
            return string.Empty;
        }
    
        //....

Took me a while to figure since I didn't want to use [Route] multiple times.

For python 3.7:

1. On windows command prompt, type: "py -m pip install pip-autoremove". You will get a successful message.

2. Change directory, if you didn't add the following as your PATH: cd C:\Users{user_name}\AppData\Local\Programs\Python\Python37-32\Scripts To know where your package/application has been installed/located, type: "where program_name" like> where jupyter If you didn't find a location, you need to add the location in PATH.

3. Type: pip-autoremove jupyter It will ask to type y/n to confirm the action.

After trying all the most upvoted answers and failing to make it work, I figured that my Android Simulator was on Airplane mode. Quite silly but posting this so it could save some time.

P.S. I had a safe reboot on my Simulator before this, which is probably the cause why my simulator booted in Airplane mode

MySQL will assume the part before the equals references the columns named in the INSERT INTO clause, and the second part references the SELECT columns.

INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, 
                inact, inadur, inadist, 
                smlct, smldur, smldist, 
                larct, lardur, lardist, 
                emptyct, emptydur)
SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct,

This happened to me because I was using:

app.datasource.url=jdbc:mysql://localhost/test

When I replaced url by jdbc-url then it worked:

app.datasource.jdbc-url=jdbc:mysql://localhost/test

Here's some Python 2 / Python 3 code that generates timing information for both list-based and set-based methods of finding the intersection of two lists.

The pure list comprehension algorithms are O(n^2), since in on a list is a linear search. The set-based algorithms are O(n), since set search is O(1), and set creation is O(n) (and converting a set to a list is also O(n)). So for sufficiently large n the set-based algorithms are faster, but for small n the overheads of creating the set(s) make them slower than the pure list comp algorithms.

These figures are only a rough guide, since the actual speeds of the various algorithms are affected differently by the proportion of elements that are in both source lists.

The problem was that you opened the Node.js repl while everyone automatically assumed you were in the command prompt. For what it's worth you can run a javascript file from the repl with the .load command. For example:

.load c:/users/username/documents/script.js

The same command can also be used in the command prompt if you first start node inside the command prompt by entering node with no arguments (assuming node is in PATH).

I find it fascinating that 1)everyone assumed you were in the command prompt rather than repl, 2)no one seems to know about .load, and 3)this has 273 upvotes, proving that a lot of other node.js beginners are similarly confused.

jenv exec bash

echo $JAVA_HOME

Is there any advantage in creating a temporary file in a more careful way

The temporary files are usually created in the temporary directory (such as /tmp) where all other users and processes has read and write access (any other script can create the new files there). Therefore the script should be careful about creating the files such as using with the right permissions (e.g. read only for the owner, see: help umask) and filename should be be not easily guessed (ideally random). Otherwise if the filenames aren't unique, it can create conflict with the same script ran multiple times (e.g. race condition) or some attacker could either hijack some sensitive information (e.g. when permissions are too open and filename is easy to guess) or create/replacing the file with their own version of the code (like replacing the commands or SQL queries depending on what is being stored).

You could use the following approach to create the temporary directory:

TMPDIR=".${0##*/}-$$" && mkdir -v "$TMPDIR"

or temporary file:

TMPFILE=".${0##*/}-$$" && touch "$TMPFILE"

However it is still predictable and not considered safe.

As per man mktemp, we can read:

Traditionally, many shell scripts take the name of the program with the pid as a suffix and use that as a temporary file name. This kind of naming scheme is predictable and the race condition it creates is easy for an attacker to win.

So to be safe, it is recommended to use mktemp command to create unique temporary file or directory (-d).

While creating a Virtual Device select the ARM system Image. Others have suggested to install HAXM, but the truth is haxm wont work on amd platform or even if it does as android studio does not supports amd-vt on windows the end result will still be a very very slow emulator to run and operate. My recommendation would be to either use alternative emulator like Genymotion (works like a charm with Gapps installed) or switch to linux as then you will get the benefit of amd-vt and emulator will run a lot faster.

You can set the line-height in pixels instead of percentage. Is that what you mean?

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("listfile.txt")
Dim inFile: Set inFile = obj.OpenTextFile("listfile.txt")

' read file
data = inFile.ReadAll
inFile.Close

' write file
outFile.write (data)
outFile.Close

Going with the two answers as mentioned above. The first one

resourcesloader.class.getClassLoader().getResource("package1/resources/repository/SSL-Key/cert.jks").toString();
resourcesloader.class.getResource("repository/SSL-Key/cert.jks").toString()

Should be one and same thing?

You can do series of replaces like that:

function format(str)
{
    for(i = 1; i < arguments.length; i++)
    {
        str = str.replace('{' + (i - 1) + '}', arguments[i]);
    }
    return str;
}

Better approach will be to use replace with function parameter:

function format(str, obj) {
    return str.replace(/\{\s*([^}\s]+)\s*\}/g, function(m, p1, offset, string) {
        return obj[p1]
    })
}

This way you can provide both indices and named parameters:

var arr = ['0000', '1111', '2222']

arr.a = 'aaaa'

str = format(" { 0 } , {1}, { 2}, {a}", arr)
// returns 0000 , 1111, 2222, aaaa

I think this is what you're looking for:

You don't even need to use do and done. For infinite loops I find it more readable to use for with curly brackets. For example:

for ((;;)) { date ; sleep 1 ; }

This works in bash and zsh. Doesn't work in sh.

CMD:

reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
reg query HKEY_CURRENT_USER\Environment

PowerShell:

Get-Item "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
Get-Item HKCU:\Environment

Powershell/.NET: (see EnvironmentVariableTarget Enum)

[System.Environment]::GetEnvironmentVariables([System.EnvironmentVariableTarget]::Machine)
[System.Environment]::GetEnvironmentVariables([System.EnvironmentVariableTarget]::User)

Insert "checkbox". Every time you check or uncheck the box the sheet recalculates. If you put the text size for the checkbox at 2, the color at almost black and the cell shade to black, it becomes a button that recalculates.

for those like me who are looking to send objects other than primitives, since you can't create a parameterized constructor in your fragment, just add a setter accessor in your fragment, this always works for me.

The important thing about a sprint is that: within a sprint the functionality that is to be delivered is fixed.

A sprint is normally an iteration. But you can for example have a 4 week sprint, but have 4 one week "internal" iterations within that sprint.

There is a lot of discussion about the length of sprints. I think that if you do it according to the book they should all be the same length.

We have found that a short first sprint to get the development environment up and running, followed by longer basic functionality sprints, then short sprints towards the end of the project, has worked for us.

Neither optional parameters nor function overloading are supported in Go. Go does support a variable number of parameters: Passing arguments to ... parameters

The invisibility can also be due to timing when the element is supposed to slowly appear. Forcing the browser to wait a bit might help in that case.

See, e.g., the question on letting WebDriver wait until an element is present.

TL;DR

>>> import pandas as pd
>>> df = pd.DataFrame({'Position':[1,2,3,4,5], 'Letter':['a', 'b', 'c', 'd', 'e']})
>>> dict(sorted(df.values.tolist())) # Sort of sorted... 
{'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
>>> from collections import OrderedDict
>>> OrderedDict(df.values.tolist())
OrderedDict([('a', 1), ('b', 2), ('c', 3), ('d', 4), ('e', 5)])

In Long

Explaining solution: dict(sorted(df.values.tolist()))

Given:

df = pd.DataFrame({'Position':[1,2,3,4,5], 'Letter':['a', 'b', 'c', 'd', 'e']})

[out]:

 Letter Position
0   a   1
1   b   2
2   c   3
3   d   4
4   e   5

Try:

# Get the values out to a 2-D numpy array, 
df.values

[out]:

array([['a', 1],
       ['b', 2],
       ['c', 3],
       ['d', 4],
       ['e', 5]], dtype=object)

Then optionally:

# Dump it into a list so that you can sort it using `sorted()`
sorted(df.values.tolist()) # Sort by key

Or:

# Sort by value:
from operator import itemgetter
sorted(df.values.tolist(), key=itemgetter(1))

[out]:

[['a', 1], ['b', 2], ['c', 3], ['d', 4], ['e', 5]]

Lastly, cast the list of list of 2 elements into a dict.

dict(sorted(df.values.tolist())) 

[out]:

{'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}

Answering @sbradbio comment:

If there are multiple values for a specific key and you would like to keep all of them, it's the not the most efficient but the most intuitive way is:

from collections import defaultdict
import pandas as pd

multivalue_dict = defaultdict(list)

df = pd.DataFrame({'Position':[1,2,4,4,4], 'Letter':['a', 'b', 'd', 'e', 'f']})

for idx,row in df.iterrows():
    multivalue_dict[row['Position']].append(row['Letter'])

[out]:

>>> print(multivalue_dict)
defaultdict(list, {1: ['a'], 2: ['b'], 4: ['d', 'e', 'f']})

For Windows:

• Open device manager
• Find Unknown "Android" device (likely listed under Other devices with an exclamation mark)
• Update driver
• Browse my computer for driver software
• Let me pick from a list of devices, select List All Devices
• Under "Android device" or "Google Inc", you will find "Android Bootloader Interface"
• Choose "Android Bootloader Interface"
• Click "yes" when it says that driver might not be compatible

Run dos2unix or similar utility on it to remove the carriage returns (^M).

This message indicates that your file has dos-style lineendings:

-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory 

Utilities like dos2unix will fix it:

 dos2unix <backup.bash >improved-backup.sh 

Or, if no such utility is installed, you can accomplish the same thing with translate:

tr -d "\015\032" <backup.bash >improved-backup.sh 

As for how those characters got there in the first place, @MadPhysicist had some good comments.

The breakdown of your declaration and its members is somewhat littered:

Remove the typedef

The typedef is neither required, not desired for class/struct declarations in C++. Your members have no knowledge of the declaration of pos as-written, which is core to your current compilation failure.

Change this:

typedef struct {....} pos;

To this:

struct pos { ... };

Remove extraneous inlines

You're both declaring and defining your member operators within the class definition itself. The inline keyword is not needed so long as your implementations remain in their current location (the class definition)

Return references to *this where appropriate

This is related to an abundance of copy-constructions within your implementation that should not be done without a strong reason for doing so. It is related to the expression ideology of the following:

a = b = c;

This assigns c to b, and the resulting value b is then assigned to a. This is not equivalent to the following code, contrary to what you may think:

a = c;
b = c;

Therefore, your assignment operator should be implemented as such:

pos& operator =(const pos& a)
{
    x = a.x;
    y = a.y;
    return *this;
}

Even here, this is not needed. The default copy-assignment operator will do the above for you free of charge (and code! woot!)

Note: there are times where the above should be avoided in favor of the copy/swap idiom. Though not needed for this specific case, it may look like this:

pos& operator=(pos a) // by-value param invokes class copy-ctor
{
    this->swap(a);
    return *this;
}

Then a swap method is implemented:

void pos::swap(pos& obj)
{
    // TODO: swap object guts with obj
}

You do this to utilize the class copy-ctor to make a copy, then utilize exception-safe swapping to perform the exchange. The result is the incoming copy departs (and destroys) your object's old guts, while your object assumes ownership of there's. Read more the copy/swap idiom here, along with the pros and cons therein.

Pass objects by const reference when appropriate

All of your input parameters to all of your members are currently making copies of whatever is being passed at invoke. While it may be trivial for code like this, it can be very expensive for larger object types. An exampleis given here:

Change this:

bool operator==(pos a) const{
    if(a.x==x && a.y== y)return true;
    else return false;
}

To this: (also simplified)

bool operator==(const pos& a) const
{
    return (x == a.x && y == a.y);
}

No copies of anything are made, resulting in more efficient code.

Finally, in answering your question, what is the difference between a member function or operator declared as const and one that is not?

A const member declares that invoking that member will not modifying the underlying object (mutable declarations not withstanding). Only const member functions can be invoked against const objects, or const references and pointers. For example, your operator +() does not modify your local object and thus should be declared as const. Your operator =() clearly modifies the local object, and therefore the operator should not be const.

Summary

struct pos
{
    int x;
    int y;

    // default + parameterized constructor
    pos(int x=0, int y=0) 
        : x(x), y(y)
    {
    }

    // assignment operator modifies object, therefore non-const
    pos& operator=(const pos& a)
    {
        x=a.x;
        y=a.y;
        return *this;
    }

    // addop. doesn't modify object. therefore const.
    pos operator+(const pos& a) const
    {
        return pos(a.x+x, a.y+y);
    }

    // equality comparison. doesn't modify object. therefore const.
    bool operator==(const pos& a) const
    {
        return (x == a.x && y == a.y);
    }
};

EDIT OP wanted to see how an assignment operator chain works. The following demonstrates how this:

a = b = c;

Is equivalent to this:

b = c;
a = b;

And that this does not always equate to this:

a = c;
b = c;

Sample code:

#include <iostream>
#include <string>
using namespace std;

struct obj
{
    std::string name;
    int value;

    obj(const std::string& name, int value)
        : name(name), value(value)
    {
    }

    obj& operator =(const obj& o)
    {
        cout << name << " = " << o.name << endl;
        value = (o.value+1); // note: our value is one more than the rhs.
        return *this;
    }    
};

int main(int argc, char *argv[])
{

    obj a("a", 1), b("b", 2), c("c", 3);

    a = b = c;
    cout << "a.value = " << a.value << endl;
    cout << "b.value = " << b.value << endl;
    cout << "c.value = " << c.value << endl;

    a = c;
    b = c;
    cout << "a.value = " << a.value << endl;
    cout << "b.value = " << b.value << endl;
    cout << "c.value = " << c.value << endl;

    return 0;
}

Output

b = c
a = b
a.value = 5
b.value = 4
c.value = 3
a = c
b = c
a.value = 4
b.value = 4
c.value = 3

function Update(key, value)
{    
    for (var i = 0; i < array.length; i++) {
        if (array[i].Key == key) {
            array[i].Value = value; 
            break;
        }
    }
}

In my case the imports of real routes in app.component.spec.ts were causing these error messages. Solution was to import RouterTestingModule instead.

import { TestBed, async } from '@angular/core/testing';
import { AppComponent } from './app.component';
import { RouterTestingModule } from '@angular/router/testing';

describe('AppComponent', () => {
  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [
        AppComponent
      ],
      imports: [RouterTestingModule]
    }).compileComponents();
  }));

  it('should create the app', async(() => {
    const fixture = TestBed.createComponent(AppComponent);
    console.log(fixture);
    const app = fixture.debugElement.componentInstance;
    expect(app).toBeTruthy();
  }));

});

Just store the index generated in a variable, and then access the array using this varaible:

int idx = new Random().nextInt(fruits.length);
String random = (fruits[idx]);

P.S. I usually don't like generating new Random object per randoization - I prefer using a single Random in the program - and re-use it. It allows me to easily reproduce a problematic sequence if I later find any bug in the program.

According to this approach, I will have some variable Random r somewhere, and I will just use:

int idx = r.nextInt(fruits.length)

However, your approach is OK as well, but you might have hard time reproducing a specific sequence if you need to later on.

var cumulativeOffset = function(element) {
    var top = 0, left = 0;
    do {
        top += element.offsetTop  || 0;
        left += element.offsetLeft || 0;
        element = element.offsetParent;
    } while(element);

    return {
        top: top,
        left: left
    };
};

You're most likely using this on a local file over the file:// URI scheme, which cannot have cookies set. Put it on a local server so you can use http://localhost.

I'm using the following in VC++ and it works like a charm for me.

According to your CSS file path, I will suppose it is at the same directory with your HTML page, you have to change the url as follows:

body { background: url(img/debut_dark.png) repeat 0 0; }

It seems like your question has been answered but now you might wonder why char *a = "String" is stored in read-only memory. Well, it is actually left undefined by the c99 standard but most compilers choose to it this way for instances like:

printf("Hello, World\n");

c99 standard(pdf) [page 130, section 6.7.8]:

The declaration:

char s[] = "abc", t[3] = "abc";

defines "plain" char array objects s and t whose elements are initialized with character string literals. This declaration is identical to char

s[] = { 'a', 'b', 'c', '\0' }, t[] = { 'a', 'b', 'c' };

The contents of the arrays are modifiable. On the other hand, the declaration

char *p = "abc";

defines p with type "pointer to char" and initializes it to point to an object with type "array of char" with length 4 whose elements are initialized with a character string literal. If an attempt is made to use p to modify the contents of the array, the behavior is undefined.

If you have many sourcesets/modules it can be cumbersome to configure the jvmTarget for each of them separately.

You can configure the jvmTarget for all of them at once like so:

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

This snippet can be used on top level of your gradle.build file

After modifying the gradle file Reimport All Gradle Imports. To check if it worked, open Project Structure and verify that IntelliJ correctly assigned JVM 1.8 to all Kotlin-Modules. It should look like this:

I would not recommend changing the platform directly in IntelliJ, because anyone else cloning your project for the first time is likely to face the same issue. Configuring it correctly in gradle has the advantage that IntelliJ is going to behave correctly for them right from the start.

I needed to adapt this to

error_reporting = E_ALL & ~E_DEPRECATED

For bar graphs, you can include the angle which you finally want the ticks to have.

Here I am using rot=0 to make them parallel to the x axis.

series.plot.bar(rot=0)
plt.show()
plt.close()

I think this is the best solution for this type error. So please add below line. Also it work my code when I am using MSVS 2015.

<configuration>
<appSettings>
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>

This is for dynamic # of weeks.

Full example here:SQL Dynamic Pivot

DECLARE @DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE @ColumnName AS NVARCHAR(MAX)

--Get distinct values of the PIVOT Column 
SELECT @ColumnName= ISNULL(@ColumnName + ',','') + QUOTENAME(Week)
FROM (SELECT DISTINCT Week FROM #StoreSales) AS Weeks

--Prepare the PIVOT query using the dynamic 
SET @DynamicPivotQuery = 
  N'SELECT Store, ' + @ColumnName + ' 
    FROM #StoreSales
    PIVOT(SUM(xCount) 
          FOR Week IN (' + @ColumnName + ')) AS PVTTable'
--Execute the Dynamic Pivot Query

Three simple rules:

• Only #import the super class, and adopted protocols, in header files (.h files).
• #import all classes, and protocols, you send messages to in implementation (.m files).
• Forward declarations for everything else.

If you do forward declaration in the implementation files, then you probably do something wrong.

You can use the getGraphics method of the component on which you would like to draw. This in turn should allow you to draw lines and make other things which are available through the Graphics class

First of all, you are in a bad position now - having the task of writing tests for the code you did not originally create and without any changes - nightmare! Talk to your boss and explain, it is not possible to test the code without making it "testable". To make code testable you usually do some important changes;

Regarding private variables. You actually never should do that. Aiming to test private variables is the first sign that something wrong with the current design. Private variables are part of the implementation, tests should focus on behavior rather of implementation details.

Sometimes, private field are exposed to public access with some getter. I do that, but try to avoid as much as possible (mark in comments, like 'used for testing').

Since you have no possibility to change the code, I don't see possibility (I mean real possibility, not like Reflection hacks etc.) to check private variable.

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

If you have ERROR 1064 (42000) or ERROR 1046 (3D000): No database selected in Mysql 5.7, you must specify the location of the user table, the location is mysql.table_name Then the code will work.

I never had time to play with clojure. But for scala vs groovy, this is words from James Strachan - Groovy creator

"Though my tip though for the long term replacement of javac is Scala. I'm very impressed with it! I can honestly say if someone had shown me the Programming in Scala book by Martin Odersky, Lex Spoon & Bill Venners back in 2003 I'd probably have never created Groovy."

I found the foreach loop which iterating through a List faster. See my test results below. In the code below I iterate an array of size 100, 10000 and 100000 separately using for and foreach loop to measure the time.

private static void MeasureTime()
    {
        var array = new int[10000];
        var list = array.ToList();
        Console.WriteLine("Array size: {0}", array.Length);

        Console.WriteLine("Array For loop ......");
        var stopWatch = Stopwatch.StartNew();
        for (int i = 0; i < array.Length; i++)
        {
            Thread.Sleep(1);
        }
        stopWatch.Stop();
        Console.WriteLine("Time take to run the for loop is {0} millisecond", stopWatch.ElapsedMilliseconds);

        Console.WriteLine(" ");
        Console.WriteLine("Array Foreach loop ......");
        var stopWatch1 = Stopwatch.StartNew();
        foreach (var item in array)
        {
            Thread.Sleep(1);
        }
        stopWatch1.Stop();
        Console.WriteLine("Time take to run the foreach loop is {0} millisecond", stopWatch1.ElapsedMilliseconds);

        Console.WriteLine(" ");
        Console.WriteLine("List For loop ......");
        var stopWatch2 = Stopwatch.StartNew();
        for (int i = 0; i < list.Count; i++)
        {
            Thread.Sleep(1);
        }
        stopWatch2.Stop();
        Console.WriteLine("Time take to run the for loop is {0} millisecond", stopWatch2.ElapsedMilliseconds);

        Console.WriteLine(" ");
        Console.WriteLine("List Foreach loop ......");
        var stopWatch3 = Stopwatch.StartNew();
        foreach (var item in list)
        {
            Thread.Sleep(1);
        }
        stopWatch3.Stop();
        Console.WriteLine("Time take to run the foreach loop is {0} millisecond", stopWatch3.ElapsedMilliseconds);
    }

UPDATED

After @jgauffin suggestion I used @johnskeet code and found that the for loop with array is faster than following,

• Foreach loop with array.
• For loop with list.
• Foreach loop with list.

See my test results and code below,

private static void MeasureNewTime()
    {
        var data = new double[Size];
        var rng = new Random();
        for (int i = 0; i < data.Length; i++)
        {
            data[i] = rng.NextDouble();
        }
        Console.WriteLine("Lenght of array: {0}", data.Length);
        Console.WriteLine("No. of iteration: {0}", Iterations);
        Console.WriteLine(" ");
        double correctSum = data.Sum();

        Stopwatch sw = Stopwatch.StartNew();
        for (int i = 0; i < Iterations; i++)
        {
            double sum = 0;
            for (int j = 0; j < data.Length; j++)
            {
                sum += data[j];
            }
            if (Math.Abs(sum - correctSum) > 0.1)
            {
                Console.WriteLine("Summation failed");
                return;
            }
        }
        sw.Stop();
        Console.WriteLine("For loop with Array: {0}", sw.ElapsedMilliseconds);

        sw = Stopwatch.StartNew();
        for (var i = 0; i < Iterations; i++)
        {
            double sum = 0;

Something like...

Minutes.minutesBetween(getStart(), getEnd()).getMinutes();

Find the below code to make visible the view in Circuler reveal, if you send true, it'll get Invisible/Gone. If you send false, it'll get visible. anyView is the view you're going to visible/hide, it could be any view (Layouts, Buttons etc)

 private fun toggle(flag: Boolean, anyView: View) {
    if (flag) {
        val cx = anyView.width / 2
        val cy = anyView.height / 2
        val initialRadius = Math.hypot(cx.toDouble(), cy.toDouble()).toFloat()
        val anim = ViewAnimationUtils.createCircularReveal(anyView, cx, cy, initialRadius, 0f)
        anim.addListener(object : AnimatorListenerAdapter() {
            override fun onAnimationEnd(animation: Animator) {
                super.onAnimationEnd(animation)
                anyView.visibility = View.INVISIBLE
            }
        })
        anim.start()
    } else {
        val cx = anyView.width / 2
        val cy = anyView.height / 2
        val finalRadius = Math.hypot(cx.toDouble(), cy.toDouble()).toFloat()
        val anim = ViewAnimationUtils.createCircularReveal(anyView, cx, cy, 0f, finalRadius)
        anyView.visibility = View.VISIBLE
        anim.start()
    }
}

The question is pretty old, but nowadays you can use forEach, which is efficient and will retain the keys as numbers:

let keys = widthRange.map((v,k) => k).filter(i=>i!==undefined))

This loops through widthRange and makes a new array with the value of the keys, and then filters out all sparce slots by only taking the values that are defined.

(Bad idea, but for thorughness: If slot 0 was always empty, that could be shortened to filter(i=>i) or filter(Boolean)

And, it may be less efficient, but the numbers can be cast with let keys = Object.keys(array).map(i=>i*1)

First deactivate the environment and come back to the base environment. From the base, you should be able to run the command conda env remove -n <envname>. This will give you the message

Remove all packages in environment C:\Users\<username>\AppData\Local\Continuum\anaconda3\envs\{envname}:

For route controller method we have to define only one route. In get or post method we have to define the route separately.

And the resources method is used to creates multiple routes to handle a variety of Restful actions.

Here the Laravel documentation about this.

To save a range and then call it later, you were just missing the "Set"

Set Remember_Range = Selection    or    Range("A3")
Remember_Range.Activate

But for copying and pasting, this quicker. Cuts out the middle man and its one line

Sheets("Copy").Range("A3").Value = Sheets("Paste").Range("A3").Value

<?php
$names = array("firstname"=>"maurice",
               "lastname"=>"muteti", 
               "contact"=>"7844433339");

foreach ($names as $name => $value) {
    echo $name." ".$value."</br>";
}

print_r($names);
?>

I've tried AppGameKit, It's both c++ and Basic. It's very easy to code 2d games in the Basic varient, with physics, collision and heaps more. It's also in active development, and really cheap (65$). The main problem is that it's really hard to compile for Android (you need to download heaps of files and follow difficult guides and things like that) My opinion is that it isn't yet good enough for commercial use, but is good for indie programmers It's got a medium size community

The problem is that $money is an array and you are treating it like a string or a variable which can be easily converted to string. You should say something like:

 '.... Money:'.$money['money']

I have used the following method in a project and it's working successfully.

private string identifier(string wmiClass, string wmiProperty)
//Return a hardware identifier
{
    string result = "";
    System.Management.ManagementClass mc = new System.Management.ManagementClass(wmiClass);
    System.Management.ManagementObjectCollection moc = mc.GetInstances();
    foreach (System.Management.ManagementObject mo in moc)
    {
        //Only get the first one
        if (result == "")
        {
            try
            {
                result = mo[wmiProperty].ToString();
                break;
            }
            catch
            {
            }
        }
    }
    return result;
}

you can call the above method as mentioned below,

string modelNo = identifier("Win32_DiskDrive", "Model");
string manufatureID = identifier("Win32_DiskDrive", "Manufacturer");
string signature = identifier("Win32_DiskDrive", "Signature");
string totalHeads = identifier("Win32_DiskDrive", "TotalHeads");

If you need a unique identifier, use a combination of these IDs.

this will provide exact output

import csv

import collections

with open('file.csv', 'rb') as f:

  data = list(csv.reader(f))

counter = collections.defaultdict(int)

for row in data:

    counter[row[0]] += 1

writer = csv.writer(open("file1.csv", 'w'))

for row in data:

    if counter[row[0]] >= 1:

        writer.writerow(row)

Closures can avoid creating unnecessary objects.

const decodingHandler = (() => {
  const element = document.createElement('div');
  return text => {
    element.innerHTML = text;
    return element.textContent;
  };
})();

A more concise way

const decodingHandler = (() => {
  const element = document.createElement('div');
  return text => ((element.innerHTML = text), element.textContent);
})();

Since it is hard to find good themes for IntelliJ IDEA, I've created this site: https://github.com/sdvoynikov/color-themes (note: site archived to GitHub repo) where there is a large collection of themes. There are 270 themes for now and the site is growing.

P.S.: Help me and other people — do not forget to upvote when you download themes from this site!

Just weighing in here with a nice solution I have been using. This is similar to Lucky Soni's solution above in that it supports aggregation, but doesn't require hard coding of the field names.

cursor = db.<collection_name>.<my_query_with_aggregation>;

headerPrinted = false;
while (cursor.hasNext()) {
    item = cursor.next();
    
    if (!headerPrinted) {
        print(Object.keys(item).join(','));
        headerPrinted = true;
    }

    line = Object
        .keys(item)
        .map(function(prop) {
            return '"' + item[prop] + '"';
        })
        .join(',');
    print(line);
}

Save this as a .js file, in this case we'll call it example.js and run it with the mongo command line like so:

mongo <database_name> example.js --quiet > example.csv

This can be done using jQuery.

Here is a link to a fiddle.

When the window scrolls, the distance between the top of the window and the height of the window is compared. When the if statement is true, the background color is set to transparent. And when you scroll back to the top the color comes back to white.

$(document).ready(function(){
    $(window).scroll(function(){
        if($(window).scrollTop() > $(window).height()){
            $(".menu").css({"background-color":"transparent"});   
        }
        else{
            $(".menu").css({"background-color":"white"});
        }

    })
})

        da.Fill(dt)

        For i As Integer = 0 To dt.Rows.Count
            someVar = dt.Rows(i)("fieldName")
        Next

    else if (vi_video[0].oExitFullScreen) vi_video[0].oExitFullScreen();
    else if (vi_video[0].msExitFullScreen) vi_video[0].msExitFullScreen();
    else { vi_video.parent().append(vi_video.remove()); }

Your main problem is you create new figures in your loop, so each vector gets drawn on a different figure. Here's what I came up with, let me know if it's still not what you expect:

CODE:

import numpy as np
import matplotlib.pyplot as plt
M = np.array([[1,1],[-2,2],[4,-7]])

rows,cols = M.T.shape

#Get absolute maxes for axis ranges to center origin
#This is optional
maxes = 1.1*np.amax(abs(M), axis = 0)

for i,l in enumerate(range(0,cols)):
    xs = [0,M[i,0]]
    ys = [0,M[i,1]]
    plt.plot(xs,ys)

plt.plot(0,0,'ok') #<-- plot a black point at the origin
plt.axis('equal')  #<-- set the axes to the same scale
plt.xlim([-maxes[0],maxes[0]]) #<-- set the x axis limits
plt.ylim([-maxes[1],maxes[1]]) #<-- set the y axis limits
plt.legend(['V'+str(i+1) for i in range(cols)]) #<-- give a legend
plt.grid(b=True, which='major') #<-- plot grid lines
plt.show()

OUTPUT:

EDIT CODE:

import numpy as np
import matplotlib.pyplot as plt
M = np.array([[1,1],[-2,2],[4,-7]])

rows,cols = M.T.shape

#Get absolute maxes for axis ranges to center origin
#This is optional
maxes = 1.1*np.amax(abs(M), axis = 0)
colors = ['b','r','k']


for i,l in enumerate(range(0,cols)):
    plt.axes().arrow(0,0,M[i,0],M[i,1],head_width=0.05,head_length=0.1,color = colors[i])

plt.plot(0,0,'ok') #<-- plot a black point at the origin
plt.axis('equal')  #<-- set the axes to the same scale
plt.xlim([-maxes[0],maxes[0]]) #<-- set the x axis limits
plt.ylim([-maxes[1],maxes[1]]) #<-- set the y axis limits
plt.grid(b=True, which='major') #<-- plot grid lines
plt.show()

EDIT OUTPUT:

  -moz-transform: scale(2); /* FF */

It would depend on the browser's default stylesheet. You can view an (unofficial) table of CSS2.1 User Agent stylesheet defaults here.

Based on the page listed above, the default sizes look something like this:

Also worth taking a look at is the default stylesheet for HTML 4. The W3C recommends using these styles as the default. An abridged excerpt:

h1 { font-size: 2em; }
h2 { font-size: 1.5em; }
h3 { font-size: 1.17em; }
h4 { font-size: 1.12em; }
h5 { font-size: .83em; }
h6 { font-size: .75em; }

Hope this information is helpful.

After struggling for many days finally found a solution that works perfectly.

Mac OS open ~/Library folder (in your home directory) and delete the VirtulBox folder. This will remove all configurations and you can start the virtual box again!

Others look for .virtualbox folder in your home directory. Remove it and open VirtualBox should solve your issue.

Cheers!!

You're looking for UPDATE not insert.

UPDATE mytable
SET    table_column = 'test';

UPDATE will change the values of existing rows (and can include a WHERE to make it only affect specific rows), whereas INSERT is adding a new row (which makes it look like it changed only the last row, but in effect is adding a new row with that value).

To accomplish what you want, use an array Like Rabbot said (though this can become a pain to document/maintain if used excessively). Or just use the traditional optional args.

//My function with tons of optional params
function my_func($req_a, $req_b, $opt_a = NULL, $opt_b = NULL, $opt_c = NULL)
{
  //Do stuff
}
my_func('Hi', 'World', null, null, 'Red');

However, I usually find that when I start writing a function/method with that many arguments - more often than not it is a code smell, and can be re-factored/abstracted into something much cleaner.

//Specialization of my_func - assuming my_func itself cannot be refactored
function my_color_func($reg_a, $reg_b, $opt = 'Red')
{
  return my_func($reg_a, $reg_b, null, null, $opt);
}
my_color_func('Hi', 'World');
my_color_func('Hello', 'Universe', 'Green');

Simply run this in a terminal (on MacOS or Linux):

crc32 <(echo "some string")

8 characters long.

Tried this yet?

error_reporting(0);
@ini_set('display_errors', 0);

I'd like to emphasize that order of arguments is important.

For me java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8000 -jar app.jar command opens debugger port,

but java -jar app.jar -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8000 command doesn't.

If you use Flutter, then you can access it via people.googleapis.com endpoint, code uses google_sign_in library

import 'package:google_sign_in/google_sign_in.dart';

Future<String> getPhotoUrl(GoogleSignInAccount account, String userId) async {
  // final authentication = await account.authentication;
  final url = 'https://people.googleapis.com/v1/people/${userId}?personFields=photos';
  final response = await http.get(
    url,
    headers: await account.authHeaders
  );

  final data = json.decode(response.body);
  return data['photos'].first['url'];
}

You will get something like

{
  resourceName: people/998812322529259873423, 
  etag: %EgQBAzcabcQBAgUH, 
  photos: [{metadata: {primary: true, source: {type: PROFILE, id: 107721622529987673423}}, 
  url: https://lh3.googleusercontent.com/a-/abcdefmB2p1VWxLsNT9WSV0yqwuwo6o2Ba21sh_ra7CnrZ=s100}]
}

where url is an accessible image url.

HTML:

<video
    id="video-active"
    class="video-active"
    width="640"
    height="390"
    controls="controls">
    <source src="myvideo.mp4" type="video/mp4">
</video>
<div id="current">0:00</div>
<div id="duration">0:00</div>

JavaScript:

$(document).ready(function(){
  $("#video-active").on(
    "timeupdate", 
    function(event){
      onTrackedVideoFrame(this.currentTime, this.duration);
    });
});

function onTrackedVideoFrame(currentTime, duration){
    $("#current").text(currentTime); //Change #current to currentTime
    $("#duration").text(duration)
}

Notes:

Every 15 to 250ms, or whenever the MediaController's media controller position changes, whichever happens least often, the user agent must queue a task to fire a simple event named timeupdate at the MediaController.

OCV goes out of its way to make sure you can't do this without knowing the element type, but if you want an easily codable but not-very-efficient way to read it type-agnostically, you can use something like

double val=mean(someMat(Rect(x,y,1,1)))[channel];

To do it well, you do have to know the type though. The at<> method is the safe way, but direct access to the data pointer is generally faster if you do it correctly.

1) The function returns a cell for a table view yes? So, the returned object is of type UITableViewCell. These are the objects that you see in the table's rows. This function basically returns a cell, for a table view. But you might ask, how the function would know what cell to return for what row, which is answered in the 2nd question

2)NSIndexPath is essentially two things-

• Your Section
• Your row

Because your table might be divided to many sections and each with its own rows, this NSIndexPath will help you identify precisely which section and which row. They are both integers. If you're a beginner, I would say try with just one section.

It is called if you implement the UITableViewDataSource protocol in your view controller. A simpler way would be to add a UITableViewController class. I strongly recommend this because it Apple has some code written for you to easily implement the functions that can describe a table. Anyway, if you choose to implement this protocol yourself, you need to create a UITableViewCell object and return it for whatever row. Have a look at its class reference to understand re-usablity because the cells that are displayed in the table view are reused again and again(this is a very efficient design btw).

As for when you have two table views, look at the method. The table view is passed to it, so you should not have a problem with respect to that.

Using standard C++ calling (note that you should use namespace std for cout or add using namespace std;)

#include <iostream>

int main()
{
    std::cout<<"Hello World!\n";
    return 0;
}

@robertc has it right, but you also need to notice that svg, #container causes the svg to be scaled exponentially for anything but 100% (once for #container and once for svg).

In other words, if I applied 50% h/w to both elements, it's actually 50% of 50%, or .5 * .5, which equals .25, or 25% scale.

One selector works fine when used as @robertc suggests.

svg {
  width:50%;
  height:50%;
}

For ease of use, ctypes is the way to go.

The following example of ctypes is from actual code I've written (in Python 2.5). This has been, by far, the easiest way I've found for doing what you ask.

import ctypes

# Load DLL into memory.

hllDll = ctypes.WinDLL ("c:\\PComm\\ehlapi32.dll")

# Set up prototype and parameters for the desired function call.
# HLLAPI

hllApiProto = ctypes.WINFUNCTYPE (
    ctypes.c_int,      # Return type.
    ctypes.c_void_p,   # Parameters 1 ...
    ctypes.c_void_p,
    ctypes.c_void_p,
    ctypes.c_void_p)   # ... thru 4.
hllApiParams = (1, "p1", 0), (1, "p2", 0), (1, "p3",0), (1, "p4",0),

# Actually map the call ("HLLAPI(...)") to a Python name.

hllApi = hllApiProto (("HLLAPI", hllDll), hllApiParams)

# This is how you can actually call the DLL function.
# Set up the variables and call the Python name with them.

p1 = ctypes.c_int (1)
p2 = ctypes.c_char_p (sessionVar)
p3 = ctypes.c_int (1)
p4 = ctypes.c_int (0)
hllApi (ctypes.byref (p1), p2, ctypes.byref (p3), ctypes.byref (p4))

The ctypes stuff has all the C-type data types (int, char, short, void*, and so on) and can pass by value or reference. It can also return specific data types although my example doesn't do that (the HLL API returns values by modifying a variable passed by reference).

In terms of the specific example shown above, IBM's EHLLAPI is a fairly consistent interface.

All calls pass four void pointers (EHLLAPI sends the return code back through the fourth parameter, a pointer to an int so, while I specify int as the return type, I can safely ignore it) as per IBM's documentation here. In other words, the C variant of the function would be:

int hllApi (void *p1, void *p2, void *p3, void *p4)

This makes for a single, simple ctypes function able to do anything the EHLLAPI library provides, but it's likely that other libraries will need a separate ctypes function set up per library function.

The return value from WINFUNCTYPE is a function prototype but you still have to set up more parameter information (over and above the types). Each tuple in hllApiParams has a parameter "direction" (1 = input, 2 = output and so on), a parameter name and a default value - see the ctypes doco for details

Once you have the prototype and parameter information, you can create a Python "callable" hllApi with which to call the function. You simply create the needed variable (p1 through p4 in my case) and call the function with them.

I looked for an array wrapper which makes it comparable to use with guava TreeRangeMap. The class doesn't accept comparator.

After some research I realized that ByteBuffer from JDK has this feature and it doesn't copy original array which is good. More over you can compare faster with ByteBuffer::asLongBuffer 8 bytes at time (also doesn't copy). By default ByteBuffer::wrap(byte[]) use BigEndian so order relation is the same as comparing individual bytes.

.

Here is a simple way to use an associative array as a generic Object type:

Object.prototype.forEach = function(cb){_x000D_
   if(this instanceof Array) return this.forEach(cb);_x000D_
   let self = this;_x000D_
   Object.getOwnPropertyNames(this).forEach(_x000D_
      (k)=>{ cb.call(self, self[k], k); }_x000D_
   );_x000D_
};_x000D_
_x000D_
Object({a:1,b:2,c:3}).forEach((value, key)=>{ _x000D_
    console.log(`key/value pair: ${key}/${value}`);_x000D_
});

if you want to change default:

for bootstrap 3.x:

$.fn.modal.prototype.constructor.Constructor.DEFAULTS.backdrop = 'static';
$.fn.modal.prototype.constructor.Constructor.DEFAULTS.keyboard =  false;

for bootstrap 4.x:

$.fn.modal.prototype.constructor.Constructor.Default.backdrop = 'static';
$.fn.modal.prototype.constructor.Constructor.Default.keyboard =  false;

I think all the previous answers are wrong, as they state that dereferencing means accessing the actual value. Wikipedia gives the correct definition instead: https://en.wikipedia.org/wiki/Dereference_operator

It operates on a pointer variable, and returns an l-value equivalent to the value at the pointer address. This is called "dereferencing" the pointer.

That said, we can dereference the pointer without ever accessing the value it points to. For example:

char *p = NULL;
*p;

We dereferenced the NULL pointer without accessing its value. Or we could do:

p1 = &(*p);
sz = sizeof(*p);

Again, dereferencing, but never accessing the value. Such code will NOT crash: The crash happens when you actually access the data by an invalid pointer. However, unfortunately, according the the standard, dereferencing an invalid pointer is an undefined behaviour (with a few exceptions), even if you don't try to touch the actual data.

So in short: dereferencing the pointer means applying the dereference operator to it. That operator just returns an l-value for your future use.

It means not equal to .

It's the same as != in C-like languages. but <> is ISO Standard and

!= Not equal to (not ISO standard)

After struggling a lot I finally solved the problem.

If you are prompted to download a .php file instead of executing it, then here is the perfect solution: I assume that you have installed PHP5 already and still getting this error.

$ sudo su
$ a2enmod php5

This is it.

But If you are still getting the error :

Config file php5.conf not properly enabled: /etc/apache2/mods-enabled/php5.conf is a real file, not touching it

then do the following:

Turns out files shouldn't be stored in mods-enabled, but should rather be stored in mods-available. A symlink should then be created in mods-enabled pointing to the file stored in mods-available.

First remove the original:

$ mv /etc/apache2/mods-enabled/php5.conf /etc/apache2/mods-available/

Then create the symbolic link:

$ ln -s /etc/apache2/mods-available/php5.conf /etc/apache2/mods-enabled/php5.conf

I hope your problem is solved.

Try this one:

import Data.List (unfoldr)

separateBy :: Eq a => a -> [a] -> [[a]]
separateBy chr = unfoldr sep where
  sep [] = Nothing
  sep l  = Just . fmap (drop 1) . break (== chr) $ l

Only works for a single char, but should be easily extendable.

$(function () {
    $('#datepicker').datepicker({
        dateFormat: 'yy-mm-dd',
        showButtonPanel: true,
        changeMonth: true,
        changeYear: true,
yearRange: '1999:2012',
        showOn: "button",
        buttonImage: "images/calendar.gif",
        buttonImageOnly: true,
        minDate: new Date(1999, 10 - 1, 25),
        maxDate: '+30Y',
        inline: true
    });
});

Just added year range option. It should solve the problem

Using json, you can subclass JSONEncoder and override the default() method to provide your own custom serializers:

import json
import datetime

class DateTimeJSONEncoder(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, datetime.datetime):
            return obj.isoformat()
        else:
            return super(DateTimeJSONEncoder, self).default(obj)

Then, you can call it like this:

>>> DateTimeJSONEncoder().encode([datetime.datetime.now()])
'["2010-06-15T14:42:28"]'

I have used below code in Angular 9. note that it is using http class instead of normal httpClient.

1. so import Headers from the module, otherwise Headers will be mistaken by typescript headers interface and gives error

   import {Http, Headers, RequestOptionsArgs } from "@angular/http";

2. and in your method use following sample code and it is breaked down for easier understanding.

   let customHeaders = new Headers({ Authorization: "Bearer " + localStorage.getItem("token")});
   const requestOptions: RequestOptionsArgs = { headers: customHeaders };
   return this.http.get("/api/orders", requestOptions);
   

I will try to explain this using an example, suppose you wanted to print a fixed number of terms from fibonacci series. Remember that the first 2 terms of fibonacci series are 1s. Eg: 1, 1, 2, 3, 5, 8, 13....

You want the list containing the fibonacci numbers to be initialized only once and after that it should update. Now we can use the __call__ functionality. Read @mudit verma's answer. It's like you want the object to be callable as a function but not re-initialized every time you call it.

Eg:

class Recorder:
    def __init__(self):
        self._weights = []
        for i in range(0, 2):
            self._weights.append(1)
        print self._weights[-1]
        print self._weights[-2]
        print "no. above is from __init__"

    def __call__(self, t):
        self._weights = [self._weights[-1], self._weights[-1] + self._weights[-2]]
        print self._weights[-1]
        print "no. above is from __call__"

weight_recorder = Recorder()
for i in range(0, 10):
    weight_recorder(i)

The output is:

1
1
no. above is from __init__
2
no. above is from __call__
3
no. above is from __call__
5
no. above is from __call__
8
no. above is from __call__
13
no. above is from __call__
21
no. above is from __call__
34
no. above is from __call__
55
no. above is from __call__
89
no. above is from __call__
144
no. above is from __call__

If you observe the output __init__ was called only one time that's when the class was instantiated for the first time, later on the object was being called without re-initializing.

What about WebMatrix: http://www.microsoft.com/web/webmatrix/ ?

from here you can easily convert your excelsheet data into the html view

And if you don't want to construct an array ...

var str = "how,are you doing, today?";
var res = str.replace(/(.*)([, ])([^, ]*$)/,"$3");

The breakdown in english is:

/(anything)(any separator once)(anything that isn't a separator 0 or more times)/

The replace just says replace the entire string with the stuff after the last separator.

So you can see how this can be applied generally. Note the original string is not modified.

If all of these advice doesn't work, you should re-create your Server (Tomcat or like that). That solved my problem.

Since datatables v1.10.18, you should specify the column key instead of index, it should be like this:

rowCallback: function(row, data, index){
            if(data["column_key"] == "ValueHere"){
                $('td', row).css('background-color', 'blue');
            }
        }

The 'react-json-view' provides solution rendering json string.

import ReactJson from 'react-json-view';
<ReactJson src={my_important_json} theme="monokai" />

because it is autoincrement, here's my take:

Select * from tbl 
where certainconditionshere 
and autoincfield >= (select max(autoincfield) from tbl) - $n

If you want to cherry-pick multiple commits for a given file until you reach a given commit, then use the following.

# Directory from which to cherry-pick
GIT_DIR=...
# Pick changes only for this file
FILE_PATH=...
# Apply changes from this commit
FIST_COMMIT=master
# Apply changes until you reach this commit
LAST_COMMIT=...

for sha in $(git --git-dir=$GIT_DIR log --reverse --topo-order --format=%H $LAST_COMMIT_SHA..master -- $FILE_PATH ) ; do 
  git --git-dir=$GIT_DIR  format-patch -k -1 --stdout $sha -- $FILE_PATH | 
    git am -3 -k
done

If you want to check the python version in a particular cond environment you can also use conda list python

You're after the zip function.

Taken directly from the question: How to merge lists into a list of tuples in Python?

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> zip(list_a,list_b)
[(1, 5), (2, 6), (3, 7), (4, 8)]

(TESTED ON MACOS)

The first step is to run the emulator

emulator -avd < avd_name>

then use adb to install the .apk

adb install < path to .apk file>

If adb throws error like APK already exists or something alike. Run the adb shell while emulator is running

adb shell

cd data/app

adb uninstall < apk file without using .apk>

If adb and emulator are commands not found do following

export PATH=$PATH://android-sdk-macosx/platform-tools://android-sdk-macosx/android-sdk-macosx/tools:

For future use put the above line at the end of .bash_profile

vi ~/.bash_profile

foreach (DataRow dr in ds.Tables[0].Rows)
{
    //your code here
}

Use:

FormBorderStyle = FormBorderStyle.None;
WindowState = FormWindowState.Maximized;

And then your form is placed over the taskbar.

In case of springboot app on tomcat, I needed to create an additional class as below and this worked:

@SpringBootApplication 
public class SpringBootTomcatApplication extends SpringBootServletInitializer {
}

For a new document: Settings -> Preferences -> New Document/Default Directory -> New Document -> Format -> Windows/Mac/Unix

And for an already-open document: Edit -> EOL Conversion

Following your comment posted to ceejayoz's answer, two things are messed up a litte:

1. $first is not an array, it's a string. Replace $first = $first[0] . "%" by $first .= "%". Just for simplicity. (PHP string operators)

2. The string being compared with LIKE operator should be quoted. Replace LIKE ".$first."") by LIKE '".$first."'"). (MySQL String Comparison Functions)

Schema is a way of categorising the objects in a database. It can be useful if you have several applications share a single database and while there is some common set of data that all application accesses.

Alternatively, you can use XPathNavigator:

XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
XPathNavigator navigator = doc.CreateNavigator();

string books = GetStringValues("Books: ", navigator, "//Book/Title");
string authors = GetStringValues("Authors: ", navigator, "//Book/Author");

..

/// <summary>
/// Gets the string values.
/// </summary>
/// <param name="description">The description.</param>
/// <param name="navigator">The navigator.</param>
/// <param name="xpath">The xpath.</param>
/// <returns></returns>
private static string GetStringValues(string description,
                                      XPathNavigator navigator, string xpath) {
    StringBuilder sb = new StringBuilder();
    sb.Append(description);
    XPathNodeIterator bookNodesIterator = navigator.Select(xpath);
    while (bookNodesIterator.MoveNext())
       sb.Append(string.Format("{0} ", bookNodesIterator.Current.Value));
    return sb.ToString();
}

Because the stack is faster and leak-proof

In C++, it takes but a single instruction to allocate space -- on the stack -- for every local scope object in a given function, and it's impossible to leak any of that memory. That comment intended (or should have intended) to say something like "use the stack and not the heap".

You can't. It's not a trusted event.

Events that are generated by the user agent, either as a result of user interaction, or as a direct result of changes to the DOM, are trusted by the user agent with privileges that are not afforded to events generated by script through the DocumentEvent.createEvent("Event") method, modified using the Event.initEvent() method, or dispatched via the EventTarget.dispatchEvent() method. The isTrusted attribute of trusted events has a value of true, while untrusted events have a isTrusted attribute value of false.

Most untrusted events should not trigger default actions, with the exception of click or DOMActivate events.

You have to add a class and add/remove that on the mouseover/mouseout events manually.

Side note, I'm answering this here after I marked this as a duplicate since no answer here really covers the issue from what I see. Hopefully, one day it'll be merged.

Another approach to this issue could be to create a self extracting executable (.exe) using something like winzip and use this as the install vector rather than the zip file. Similarly, you could use NSIS to create an executable installer and use that instead of the zip.

When dealing with VARCHAR/NVARCHAR data most other examples treat white-space the same as empty string which is equal to C# function IsNullOrWhiteSpace.

This version respects white-space and works the same as the C# function IsNullOrEmpty:

IIF(ISNULL(DATALENGTH(val), 0) = 0, whenTrueValue, whenFalseValue)

Simple test:

SELECT
    '"' + val + '"' AS [StrValue],
    IIF(ISNULL(DATALENGTH(val), 0) = 0, 'TRUE', 'FALSE') AS IsNullOrEmpty
FROM ( VALUES 
    (NULL), 
    (''), 
    (' '), 
    ('a'), 
    ('a ')
) S (val)

You can use flexbox for this.

ul {
    display: flex;
    align-items: center;
}

A detailed explanation of how to use flexbox can be found here.
