this will work as you asked without CHAR(38):

update t set country = 'Trinidad and Tobago' where country = 'trinidad & '|| 'tobago';

create table table99(col1 varchar(40));
insert into table99 values('Trinidad &' || '  Tobago');
insert into table99 values('Trinidad &' || '  Tobago');
insert into table99 values('Trinidad &' || '  Tobago');
insert into table99 values('Trinidad &' || '  Tobago');
SELECT * FROM table99;

update table99 set col1 = 'Trinidad and Tobago' where col1 = 'Trinidad &'||'  Tobago';

I believe that dropping the size of the image down to an almost icon size, say 48x48, then converting to greyscale, then taking the difference between pixels, or Delta, should work well. Because we're comparing the change in pixel color, rather than the actual pixel color, it won't matter if the image is slightly lighter or darker. Large changes will matter since pixels getting too light/dark will be lost. You can apply this across one row, or as many as you like to increase the accuracy. At most you'd have 47x47=2,209 subtractions to make in order to form a comparable Key.

You need to split the string:

>>> s = 'http://www.domain.com/?s=some&two=20'
>>> s.split('&')
['http://www.domain.com/?s=some', 'two=20']

That will return a list as you can see so you can do:

>>> s2 = s.split('&')[0]
>>> print s2
http://www.domain.com/?s=some

Here's a generic version of a sproc I recently wrote for Oracle that allows for dynamic paging/sorting - HTH

-- p_LowerBound = first row # in the returned set; if second page of 10 rows,
--                this would be 11 (-1 for unbounded/not set)
-- p_UpperBound = last row # in the returned set; if second page of 10 rows,
--                this would be 20 (-1 for unbounded/not set)

OPEN o_Cursor FOR
SELECT * FROM (
SELECT
    Column1,
    Column2
    rownum AS rn
FROM
(
    SELECT
        tbl.Column1,
        tbl.column2
    FROM MyTable tbl
    WHERE
        tbl.Column1 = p_PKParam OR
        tbl.Column1 = -1
    ORDER BY
        DECODE(p_sortOrder, 'A', DECODE(p_sortColumn, 1, Column1, 'X'),'X'),
        DECODE(p_sortOrder, 'D', DECODE(p_sortColumn, 1, Column1, 'X'),'X') DESC,
        DECODE(p_sortOrder, 'A', DECODE(p_sortColumn, 2, Column2, sysdate),sysdate),
        DECODE(p_sortOrder, 'D', DECODE(p_sortColumn, 2, Column2, sysdate),sysdate) DESC
))
WHERE
    (rn >= p_lowerBound OR p_lowerBound = -1) AND
    (rn <= p_upperBound OR p_upperBound = -1);

Do you call

log4net.Config.XmlConfigurator.Configure();

somewhere to make log4net read your configuration? E.g. in Global.asax:

void Application_Start(object sender, EventArgs e) 
{
    // Code that runs on application startup

    // Initialize log4net.
    log4net.Config.XmlConfigurator.Configure();
}

Javascript now has a specific built in object called Map, you can call as follows :

   var myMap = new Map()

You can update it with .set :

   myMap.set("key0","value")

This has the advantage of methods you can use to handle look ups, like the boolean .has

  myMap.has("key1"); // evaluates to false 

You can use this before calling .get on your Map object to handle looking up non-existent keys

Here is a simple instruction:

1) Install:

nvm install 8.10.0

2) Use once per terminal

nvm use 8.10.0

3) Set up as default for all terminals

nvm alias default 8.10.0

You may need to use root permissions to perform those actions.

And don't forget to check nvm documentation for more info.

Also note that you may need to specify node version for your IDE:

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding. When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system) or larger. Data alignment means putting the data at a memory address equal to some multiple of the word size, which increases the system’s performance due to the way the CPU handles memory. To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

1. In order to align the data in memory, one or more empty bytes (addresses) are inserted (or left empty) between memory addresses which are allocated for other structure members while memory allocation. This concept is called structure padding.
2. Architecture of a computer processor is such a way that it can read 1 word (4 byte in 32 bit processor) from memory at a time.
3. To make use of this advantage of processor, data are always aligned as 4 bytes package which leads to insert empty addresses between other member’s address.
4. Because of this structure padding concept in C, size of the structure is always not same as what we think.

Actually my problem was that the command line mvn utility wouldn't see the changes for some reason. I turned on the Auto-deploy in the Deployment Scanner and there was still no difference. HOWEVER... I was twiddling around with the Eclipse environment and because I had added a JBoss server for it's Servers window I discovered I had the ability to "Add or Remove..." modules in my workspace. Once the project was added whenever I made a change to code the code change was detected by the Deployment Scanner and JBoss went thru the cycle of updating code!!! Works like a charm.

Here are the steps necessary to set this up;

First if you haven't done so add your JBoss Server to your Eclipse using File->New->Other->Server then go thru the motions of adding your JBoss AS 7 server. Being sure to locate the directory that you are using.

Once added, look down near the bottom of Eclipse to the "Servers" tab. You should see your JBoss server. Highlight it and look for "Add or Remove...". From there you should see your project.

Once added, make a small change to your code and watch JBoss go to town hot deploying for you.

Swift 4 answer based on helpful answer from @mbm29414.

Unfortunately, it requires the use of a XIB file. There doesn't appear to be an alternative.

The key parts are using a sizing cell (created only once) and registering the XIB when initializing the collection view.

Then you size each cell dynamically within the sizeForItemAt function.

// UICollectionView Vars and Constants
let CellXIBName = YouViewCell.XIBName
let CellReuseID = YouViewCell.ReuseID
var sizingCell = YouViewCell()


fileprivate func initCollectionView() {
    // Connect to view controller
    collectionView.dataSource = self
    collectionView.delegate = self

    // Register XIB
    collectionView.register(UINib(nibName: CellXIBName, bundle: nil), forCellWithReuseIdentifier: CellReuseID)

    // Create sizing cell for dynamically sizing cells
    sizingCell = Bundle.main.loadNibNamed(CellXIBName, owner: self, options: nil)?.first as! YourViewCell

    // Set scroll direction
    let layout = UICollectionViewFlowLayout()
    layout.scrollDirection = .vertical
    collectionView.collectionViewLayout = layout

    // Set properties
    collectionView.alwaysBounceVertical = true
    collectionView.alwaysBounceHorizontal = false

    // Set top/bottom padding
    collectionView.contentInset = UIEdgeInsets(top: collectionViewTopPadding, left: collectionViewSidePadding, bottom: collectionViewBottomPadding, right: collectionViewSidePadding)

    // Hide scrollers
    collectionView.showsVerticalScrollIndicator = false
    collectionView.showsHorizontalScrollIndicator = false
}


func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    // Get cell data and render post
    let data = YourData[indexPath.row]
    sizingCell.renderCell(data: data)

    // Get cell size
    sizingCell.setNeedsLayout()
    sizingCell.layoutIfNeeded()
    let cellSize = sizingCell.systemLayoutSizeFitting(UIView.layoutFittingCompressedSize)

    // Return cell size
    return cellSize
}

Replying to this 4 year old post, because this seems overcomplicated to me, at least if you're hosting on IIS.

Here's how I solved it:

using System;
using System.Net;
using System.Web;
using System.Web.Http;
...
[HttpPost]
[Route("ContactForm")]
public IHttpActionResult PostContactForm([FromBody] ContactForm contactForm)
    {
        var hostname = HttpContext.Current.Request.UserHostAddress;
        IPAddress ipAddress = IPAddress.Parse(hostname);
        IPHostEntry ipHostEntry = Dns.GetHostEntry(ipAddress);
        ...

Unlike OP, this gives me the client IP and client hostname, not the server. Perhaps they've fixed the bug since then?

I wanted it with date and the time but no seconds so I used this:

var dateWithoutSecond = new Date();
dateWithoutSecond.toLocaleTimeString([], {year: 'numeric', month: 'numeric', day: 'numeric', hour: '2-digit', minute: '2-digit'});

It produced the following output:

7/29/2020, 2:46 PM

Which was the exact thing I needed. Worked in FireFox.

You can use Internet Explorer to browse folders and files together in tree. It is a file explorer in Favorites Window. You just need replace "favorites folder" to folder which you want see as a root folder

When available, I believe that most lodash array functions will show the iteration. But sorting isn't really an iteration in the same way: when you're on the number 66, you aren't processing the fourth item in the array until it's finished. A custom sort function will loop through an array a number of times, nudging adjacent numbers forward or backward, until the everything is in its proper place.

Apart from Install Shield and WiX, there is Inno Setup. Although I haven't tried it myself I have heard good things about it.

For all of you guys who are developing from a create-react-native-app and ejected, and have this issue in development, this is what worked for me just a little detail from the accepted answer

(in project directory) mkdir android/app/src/main/assets

here comes the part that changes cos you are in development get rid of the --dev: false part:

react-native bundle --platform android --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

after that close all terminals, erase the build folder from android/app/ to make sure you start clean to build your app, open a new terminal, and

(in project directory) npm run android

will prompt the packager console (in another terminal) and build successfully

Note : Everything up here is correct,just replace sort --> sort_values() So, it becomes:

 import pandas as pd
 df = pd.read_csv('data.csv')
 df.sort_values(ascending=False,inplace=True)

Refer to the official website here.

Easy method is try os.system:

import os
text = 'this is text'
os.system("echo %s | grep 't*'" % text)

Because the error you're getting is not related to an EditText, then it's not related to your keyboard.

The errors you are getting are not a result of your code; you probably are testing on a Samsung device that has Samsung's TouchWiz.

I had the same errors, then I tested on a Nexus S (also by Samsung, but pure Android OS without TouchWiz) and I didn't get this error.

So, in your case, just ignore these errors while testing on a device! :)

This works on keyup and paste, it colors the text red when you are almost up to the limit, truncates it when you go over and alerts you to edit your text, which you can do.

var t2= /* textarea reference*/

t2.onkeyup= t2.onpaste= function(e){
    e= e || window.event;
    var who= e.target || e.srcElement;
    if(who){
        var val= who.value, L= val.length;
        if(L> 175){
            who.style.color= 'red';
        }
        else who.style.color= ''
        if(L> 180){
            who.value= who.value.substring(0, 175);
            alert('Your message is too long, please shorten it to 180 characters or less');
            who.style.color= '';
        }
    }
}

Google Chrome ignores the autocomplete="off" attribute for certain inputs, including password inputs and common inputs detected by name.

For example, if you have an input with name address, then Chrome will provide autofill suggestions from addresses entered on other sites, even if you tell it not to:

<input type="string" name="address" autocomplete="off">

If you don't want Chrome to do that, then you can rename or namespace the form field's name:

<input type="string" name="mysite_addr" autocomplete="off">

If you don't mind autocompleting values which were previously entered on your site, then you can leave autocomplete enabled. Namespacing the field name should be enough to prevent values remembered from other sites from appearing.

<input type="string" name="mysite_addr" autocomplete="on">

echo "<p><a href=\"javascript:history.go(-1)\" title=\"Return to previous page\">&laquo;Go back</a></p>";

Will go back one page.

echo "<p><a href=\"javascript:history.go(-2)\" title=\"Return to previous page\">&laquo;Go back</a></p>";

Will go back two pages.

There could be many reason why document.getElementById doesn't work

• You have an invalid ID

  ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). (resource: What are valid values for the id attribute in HTML?)

• you used some id that you already used as <meta> name in your header (e.g. copyright, author... ) it looks weird but happened to me: if your 're using IE take a look at (resource: http://www.phpied.com/getelementbyid-description-in-ie/)

• you're targeting an element inside a frame or iframe. In this case if the iframe loads a page within the same domain of the parent you should target the contentdocument before looking for the element (resource: Calling a specific id inside a frame)

• you're simply looking to an element when the node is not effectively loaded in the DOM, or maybe it's a simple misspelling

I doubt you used same ID twice or more: in that case document.getElementById should return at least the first element

Required namespace : using System.Linq;

Dictionary<string, int> counts = new Dictionary<string, int>();
counts.Add("one", 1);
counts.Add("four", 4);
counts.Add("two", 2);
counts.Add("three", 3);

Order by desc :

foreach (KeyValuePair<string, int> kvp in counts.OrderByDescending(key => key.Value))
{
// some processing logic for each item if you want.
}

Order by Asc :

foreach (KeyValuePair<string, int> kvp in counts.OrderBy(key => key.Value))
{
// some processing logic for each item if you want.
}

One more dict style clean syntax:

df["new_column"] = df.apply(lambda x: x["A"] * x["B"], axis = 1)

or,

df["new_column"] = df["A"] * df["B"]

I would suggest, you to choose a choice-parameter build, and specify the branches that you would like to build. Active Choice Parameter

And after that, you can specify branches to build. Branch to Build

Now, when you would build your project, you would be provided with "Build with Parameters, where you can choose the branch to build"

You can also write a groovy script to fetch all your branches to in active choice parameter.

For the next person Googling this topic, I've written a small NPM package to make it simple to generate Google Calendar URLs. It includes TypeScript type definitions, for those who need that. Hope it helps!

Well one way to do it is set the height of your body to the height that you want your page to be. In this example I did 600px.

Then set your wrapper height to a percentage of the body here I did 70% This will adjust your table so that it does not fill up the whole screen but in stead just takes up a percentage of the specified page height.

body {
   padding-top: 70px;
   border:1px solid black;
   height:600px;
}

.mygrid-wrapper-div {
   border: solid red 5px;
   overflow: scroll;
   height: 70%;
}

Update How about a jQuery approach.

$(function() {  
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

$( window ).resize(function() {
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

Remember if you want to give Text a backgroundcolor and then also borderRadius in that case also write overflow:'hidden' your text having a background colour will also get the radius otherwise it's impossible to achieve until unless you wrap it with View and give backgroundcolor and radius to it.

<Text style={{ backgroundColor: 'black', color:'white', borderRadius:10, overflow:'hidden'}}>Dummy</Text>

$ls -l `which sh`
/bin/sh -> dash

$sudo dpkg-reconfigure dash #Select "no" when you're asked

I am using this collection, when I worked in small elements collection.

Where elements lot, I think need use "Dictionary". My code:

NameValueCollection ProdIdes;
string prodId = _cfg.ProdIdes[key];
if (string.IsNullOrEmpty(prodId))
{
    ......
}

Or may be use this:

 string prodId = _cfg.ProdIdes[key] !=null ? "found" : "not found";

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

You are right, this is related to SQL injection, which is a vulnerability that allows a malicioius user to execute arbitrary statements against your database. This old time favorite XKCD comic illustrates the concept:

In your example, if you just use:

var query = "SELECT empSalary from employee where salary = " + txtSalary.Text;
// and proceed to execute this query

You are open to SQL injection. For example, say someone enters txtSalary:

1; UPDATE employee SET salary = 9999999 WHERE empID = 10; --
1; DROP TABLE employee; --
// etc.

When you execute this query, it will perform a SELECT and an UPDATE or DROP, or whatever they wanted. The -- at the end simply comments out the rest of your query, which would be useful in the attack if you were concatenating anything after txtSalary.Text.

The correct way is to use parameterized queries, eg (C#):

SqlCommand query =  new SqlCommand("SELECT empSalary FROM employee 
                                    WHERE salary = @sal;");
query.Parameters.AddWithValue("@sal", txtSalary.Text);

With that, you can safely execute the query.

For reference on how to avoid SQL injection in several other languages, check bobby-tables.com, a website maintained by a SO user.

METHOD 1 ( Recommanded )

Library YouTubeExtractor

Add into your gradle file

 allprojects {
        repositories {
            maven { url "https://jitpack.io" }
        }
    }

And dependencies

 compile 'com.github.Commit451.YouTubeExtractor:youtubeextractor:2.1.0'

Add this small code and you done. Demo HERE

public class MainActivity extends AppCompatActivity {

    private static final String YOUTUBE_ID = "ea4-5mrpGfE";

    private final YouTubeExtractor mExtractor = YouTubeExtractor.create();


    private Callback<YouTubeExtractionResult> mExtractionCallback = new Callback<YouTubeExtractionResult>() {
        @Override
        public void onResponse(Call<YouTubeExtractionResult> call, Response<YouTubeExtractionResult> response) {
            bindVideoResult(response.body());
        }

        @Override
        public void onFailure(Call<YouTubeExtractionResult> call, Throwable t) {
            onError(t);
        }
    };


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


//        For android youtube extractor library  com.github.Commit451.YouTubeExtractor:youtubeextractor:2.1.0'
        mExtractor.extract(YOUTUBE_ID).enqueue(mExtractionCallback);

    }


    private void onError(Throwable t) {
        t.printStackTrace();
        Toast.makeText(MainActivity.this, "It failed to extract. So sad", Toast.LENGTH_SHORT).show();
    }


    private void bindVideoResult(YouTubeExtractionResult result) {

//        Here you can get download url link
        Log.d("OnSuccess", "Got a result with the best url: " + result.getBestAvailableQualityVideoUri());

        Toast.makeText(this, "result : " + result.getSd360VideoUri(), Toast.LENGTH_SHORT).show();
    }
}

You can get download link in bindVideoResult() method.

METHOD 2

Using this library android-youtubeExtractor

Add into gradle file

repositories {
    maven { url "https://jitpack.io" }
}

compile 'com.github.HaarigerHarald:android-youtubeExtractor:master-SNAPSHOT'

Here is the code for getting download url.

       String youtubeLink = "http://youtube.com/watch?v=xxxx";

    YouTubeUriExtractor ytEx = new YouTubeUriExtractor(this) {
        @Override
        public void onUrisAvailable(String videoId, String videoTitle, SparseArray<YtFile> ytFiles) {
            if (ytFiles != null) {
                int itag = 22;
// Here you can get download url
                String downloadUrl = ytFiles.get(itag).getUrl();
            }
        }
    };

    ytEx.execute(youtubeLink);

   MySQL on Google Cloud seem to require an alternate command (mind the backticks).

   GRANT ALL PRIVILEGES ON `%`.* TO 'newuser'@'localhost';
   

3. bind to all addresses:

   The easiest way is to comment out the line in your /etc/mysql/mariadb.conf.d/50-server.cnf or /etc/mysql/mysql.conf.d/mysqld.cnf file, depending on what system you are running:

   #bind-address = 127.0.0.1 
   

4. exit mysql and restart mysql

   exit
   service mysql restart
   

By default it binds only to localhost, but if you comment the line it binds to all interfaces it finds. Commenting out the line is equivalent to bind-address=*.

To check the binding of mysql service execute as root:

netstat -tupan | grep mysql

C++14 brings generic lambdas. Meaning we can use std::for_each very easily:

std::map<int, int> myMap{{1, 2}, {3, 4}, {5, 6}, {7, 8}};

std::for_each(myMap.begin(), myMap.end(), [](const auto &myMapPair) {
    std::cout << "first " << myMapPair.first << " second "
              << myMapPair.second << std::endl;
});

I think std::for_each is sometimes better suited than a simple range based for loop. For example when you only want to loop through a subset of a map.

I've used most of them and can tell you that the best method is to test directly to each client. Once you are comfortable with sending you can send tests of your emails to gmail and if the design doesn't break then it's pretty safe on modern email clients.

You can check what is supported on which client here:

On my AIX system, I tried

nohup -p  processid>

This worked well. It continued to run my process even after closing terminal windows. We have ksh as default shell so the bg and disown commands didn't work.

Use the @RequestParam to pass a parameter to the controller handler method. In the jsp your form should have an input field with name = "id" like the following:

<input type="text" name="id" />
<input type="submit" />

Then in your controller, your handler method should be like the following:

@RequestMapping("listNotes")
public String listNotes(@RequestParam("id") int id) {
    Person person = personService.getCurrentlyAuthenticatedUser();
    model.addAttribute("person", new Person());
    model.addAttribute("listPersons", this.personService.listPersons());
    model.addAttribute("listNotes", this.notesService.listNotesBySectionId(id, person));
    return "note";
}

The DBA views are restricted. So you won't be able to query them unless you're connected as a DBA or similarly privileged user.

The ALL views show you the information you're allowed to see. Normally that would be jobs you've submitted, unless you have additional privileges.

The privileges you need are defined in the Admin Guide. Find out more.

So, either you need a DBA account or you need to chat with your DBA team about getting access to the information you need.

MySQL has a function to return a value if the result is null. You can use it on a whole query:

SELECT IFNULL( (SELECT field1 FROM table WHERE id = 123 LIMIT 1) ,'not found');

Try:

Javascript Pure:

[elem][n].style.visibility='visible';
[elem][n].focus();

Jquery:

[elem].filter(':visible').focus();

As mentioned by Santosh, I think this query is suitably fast, while not querying all the table.

To return integer result of number of data records, for a specific tablename in a particular database:

select TABLE_ROWS from information_schema.TABLES where TABLE_SCHEMA = 'database' 
AND table_name='tablename';

Here's one I made myself, don't use numbers over 170 or under 2.

function factorial(x){
 if((!(isNaN(Number(x)))) && (Number(x)<=170) && (Number(x)>=2)){
  x=Number(x);for(i=x-(1);i>=1;--i){
   x*=i;
  }
 }return x;
}

Edit 2018-10-11: It looks like there is a good chance the standard described below may not go through, consider pipelineing as an alternative (does not behave exactly the same but methods could be implemented in a similar manor).

This is exactly why I am excited about es7, in future you will be able to do something like the code below (some of the specs are not complete so use with caution, I will try to keep this up to date). But basically using the new :: bind operator, you will be able to run a method on an object as if the object's prototype contains the method. eg [Object]::[Method] where normally you would call [Object].[ObjectsMethod]

Note to do this today (24-July-16) and have it work in all browsers you will need to transpile your code for the following functionality:Import / Export, Arrow functions, Promises, Async / Await and most importantly function bind. The code below could be modfied to use only function bind if nessesary, all this functionality is neatly available today by using babel.

YourCode.js (where 'lots of work to do' must simply return a promise, resolving it when the asynchronous work is done.)

import { asyncForEach } from './ArrayExtensions.js';

await [many many elements]::asyncForEach(() => lots of work to do);

ArrayExtensions.js

export function asyncForEach(callback)
{
    return Promise.resolve(this).then(async (ar) =>
    {
        for(let i=0;i<ar.length;i++)
        {
            await callback.call(ar, ar[i], i, ar);
        }
    });
};

export function asyncMap(callback)
{
    return Promise.resolve(this).then(async (ar) =>
    {
        const out = [];
        for(let i=0;i<ar.length;i++)
        {
            out[i] = await callback.call(ar, ar[i], i, ar);
        }
        return out;
    });
};

After reading all previous ones they didn't match with my actual requirement so I implemented my own one which doesn't need any procedure or complicate statements, just I GROUP_CONCAT all values from the column I wanted to obtain the MEDIAN and applying a COUNT DIV BY 2 I extract the value in from the middle of the list like the following query does :

(POS is the name of the column I want to get its median)

(query) SELECT
SUBSTRING_INDEX ( 
   SUBSTRING_INDEX ( 
       GROUP_CONCAT(pos ORDER BY CAST(pos AS SIGNED INTEGER) desc SEPARATOR ';') 
    , ';', COUNT(*)/2 ) 
, ';', -1 ) AS `pos_med`
FROM table_name
GROUP BY any_criterial

I hope this could be useful for someone in the way many of other comments were for me from this website.

i dont like any of these, they are not clear to the reader or the potential user. I just use an anonymous function, the syntax is not as slick as a case statement, but the evaluation is similar to a case statement and not that painful. this also assumes your evaluating it within where your variables are defined.

result <- ( function() { if (x==10 | y< 5) return('foo') 
                         if (x==11 & y== 5) return('bar')
                        })()

all of those () are necessary to enclose and evaluate the anonymous function.

I recently had to resolve this issue and here's what I did :

First of all, this solution is around tuning Apache server.

Second main think is that there's a bug in the IE9 which means that the meta tag will not work, instead of this solution try this

• find/open your httpd.conf

• uncomment/or add the following line

  LoadModule headers_module modules/mod_headers.so
  

• add the following lines

  <IfModule headers_module>
      Header set X-UA-Compatible: IE=EmulateIE8
  </IfModule>
  

• save/restart your Apache server,

• browse to your page with IE9, use tools like wireshark or fiddler or use IE developer tools to check the header is there

When an element, such as a div is floated, its parent container no longer considers its height, i.e.

<div id="main">
  <div id="child" style="float:left;height:40px;"> Hi</div>
</div>

The parent container will not be be 40 pixels tall by default. This causes a lot of weird little quirks if you're using these containers to structure layout.

So the clearfix class that various frameworks use fixes this problem by making the parent container "acknowledge" the contained elements.

Day to day, I normally just use frameworks such as 960gs, Twitter Bootstrap for laying out and not bothering with the exact mechanics.

Slight modification on @JRodd version to support objects coming from Json (JObject)

public static dynamic ToDynamic(this object value)
    {
        IDictionary<string, object> expando = new ExpandoObject();

        //Get the type of object 
        Type t = value.GetType();

        //If is Dynamic Expando object
        if (t.Equals(typeof(ExpandoObject)))
        {
            foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(value.GetType()))
                expando.Add(property.Name, property.GetValue(value));
        }
        //If coming from Json object
        else if (t.Equals(typeof(JObject)))
        {
            foreach (JProperty property in (JToken)value)
                expando.Add(property.Name, property.Value);
        }
        else //Try converting a regular object
        {
            string str = JsonConvert.SerializeObject(value);
            ExpandoObject obj = JsonConvert.DeserializeObject<ExpandoObject>(str);

            return obj;
        }

       

        return expando as ExpandoObject;
    }

The easiest way is:

var oldstr="Angular isn't easy";
var newstr=oldstr.toString().replace("isn't","is");

EDIT:

This answer will not work for Python3 and will give a RuntimeError.

RuntimeError: dictionary changed size during iteration.

This happens because mydict.keys() returns an iterator not a list. As pointed out in comments simply convert mydict.keys() to a list by list(mydict.keys()) and it should work.

A simple test in the console shows you cannot modify a dictionary while iterating over it:

>>> mydict = {'one': 1, 'two': 2, 'three': 3, 'four': 4}
>>> for k, v in mydict.iteritems():
...    if k == 'two':
...        del mydict[k]
...
------------------------------------------------------------
Traceback (most recent call last):
  File "<ipython console>", line 1, in <module>
RuntimeError: dictionary changed size during iteration

As stated in delnan's answer, deleting entries causes problems when the iterator tries to move onto the next entry. Instead, use the keys() method to get a list of the keys and work with that:

>>> for k in mydict.keys():
...    if k == 'two':
...        del mydict[k]
...
>>> mydict
{'four': 4, 'three': 3, 'one': 1}

If you need to delete based on the items value, use the items() method instead:

>>> for k, v in mydict.items():
...     if v == 3:
...         del mydict[k]
...
>>> mydict
{'four': 4, 'one': 1}

Yup, when you do gem install, it will search the current directory first, so if your .gem file is there, it will pick it up. I found it on the gem reference, which you may find handy as well:

gem install will install the named gem. It will attempt a local installation (i.e. a .gem file in the current directory), and if that fails, it will attempt to download and install the most recent version of the gem you want.

This website has a simple solution to this with an example that worked for me. The line of code that does the actual leaving of space for the title is the following:

plt.tight_layout(rect=[0, 0, 1, 0.95]) 

Here is an image of proof that it worked for me:

I had a similar problem with a log4j.xml file for a unit test, did all of the above. But figured out it was because I was only re-running a failed test....if I re-run the entire test class the correct file is picked up. This is under Intelli-j 9.0.4

You can do a post/get using a library which allows you to use HttpClient with strongly-typed callbacks.

The data and the error are available directly via these callbacks.

The library is called angular-extended-http-client.

angular-extended-http-client library on GitHub

angular-extended-http-client library on NPM

Very easy to use.

Traditional approach

In the traditional approach you return Observable<HttpResponse<T>> from Service API. This is tied to HttpResponse.

With this approach you have to use .subscribe(x => ...) in the rest of your code.

This creates a tight coupling between the http layer and the rest of your code.

Strongly-typed callback approach

You only deal with your Models in these strongly-typed callbacks.

Hence, The rest of your code only knows about your Models.

Sample usage

The strongly-typed callbacks are

Success:

• IObservable<T>
• IObservableHttpResponse
• IObservableHttpCustomResponse<T>

Failure:

• IObservableError<TError>
• IObservableHttpError
• IObservableHttpCustomError<TError>

Add package to your project and in your app module

import { HttpClientExtModule } from 'angular-extended-http-client';

and in the @NgModule imports

  imports: [
    .
    .
    .
    HttpClientExtModule
  ],

Your Models

export class SearchModel {
    code: string;
}

//Normal response returned by the API.
export class RacingResponse {
    result: RacingItem[];
}

//Custom exception thrown by the API.
export class APIException {
    className: string;
}

Your Service

In your Service, you just create params with these callback types.

Then, pass them on to the HttpClientExt's get method.

import { Injectable, Inject } from '@angular/core'
import { SearchModel, RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.

@Injectable()
export class RacingService {

    //Inject HttpClientExt component.
    constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {

    }

    //Declare params of type IObservable<T> and IObservableError<TError>.
    //These are the success and failure callbacks.
    //The success callback will return the response objects returned by the underlying HttpClient call.
    //The failure callback will return the error objects returned by the underlying HttpClient call.
    searchRaceInfo(model: SearchModel, success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
        let url = this.config.apiEndpoint;

        this.client.post<SearchModel, RacingResponse>(url, model, 
                                                      ResponseType.IObservable, success, 
                                                      ErrorType.IObservableError, failure);
    }
}

Your Component

In your Component, your Service is injected and the searchRaceInfo API called as shown below.

  search() {    


    this.service.searchRaceInfo(this.searchModel, response => this.result = response.result,
                                                  error => this.errorMsg = error.className);

  }

Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

If you're asking how to serialize a single object from a model and you know you're only going to get one object in the queryset (for instance, using objects.get), then use something like:

import django.core.serializers
import django.http
import models

def jsonExample(request,poll_id):
    s = django.core.serializers.serialize('json',[models.Poll.objects.get(id=poll_id)])
    # s is a string with [] around it, so strip them off
    o=s.strip("[]")
    return django.http.HttpResponse(o, mimetype="application/json")

which would get you something of the form:

{"pk": 1, "model": "polls.poll", "fields": {"pub_date": "2013-06-27T02:29:38.284Z", "question": "What's up?"}}

there are several way, one i would prefer is using a table in html. you can add two coloum three rows table and place the radio buttons and lable.

<table border="0">

<tr>
  <td><input type="radio" name="sex" value="1"></td>
  <td>radio1</td>

</tr>
<tr>
  <td><input type="radio" name="sex" value="2"></td>
  <td>radio2</td>

</tr>
</table>

u must specify the width and height also

 <section class="bg-solid-light slideContainer strut-slide-0" style="background-image: url(https://accounts.icharts.net/stage/icharts-images/chartbook-images/Chart1457601371484.png); background-repeat: no-repeat;width: 100%;height: 100%;" >

The error occurs in 'libcurl', which is the underlying protocol for https upload. Solution is to somehow updgrade libcurl. To get more details about the error, set GIT_CURL_VERBOSE=1

https://confluence.atlassian.com/pages/viewpage.action?pageId=306348908

Meaning of error, as per libcurl doc: CURLE_HTTP_RETURNED_ERROR (22)

This is returned if CURLOPT_FAILONERROR is set TRUE and the HTTP server returns an error code that is >= 400.

http://curl.haxx.se/libcurl/c/libcurl-errors.html

There's also a cute little trick that lets you specify a single host on the command line (or multiple hosts, I guess), without an intermediary inventory:

ansible-playbook -i "imac1-local," user.yml

Note the comma (,) at the end; this signals that it's a list, not a file.

Now, this won't protect you if you accidentally pass a real inventory file in, so it may not be a good solution to this specific problem. But it's a handy trick to know!

You may be encouraged to use the Element.getBoundingClientRect() method to get the top offset of your element. This method provides the full offset values (left, top, right, bottom, width, height) of your element in the viewport.

Check the John Resig's post describing how helpful this method is.

Simply just check your run time by go to ant build configuration and change the jre against to jdk (if jdk 1.7 then jre should be 1.7) .

If you want to do a real test extract of a tar file without extracting to disk, use the -O option. This spews the extract to standard output instead of the filesystem. If the tar file is corrupt, the process will abort with an error.

Example of failed tar ball test...

$ echo "this will not pass the test" > hello.tgz
$ tar -xvzf hello.tgz -O > /dev/null
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error exit delayed from previous errors
$ rm hello.*

Working Example...

$ ls hello*
ls: hello*: No such file or directory
$ echo "hello1" > hello1.txt
$ echo "hello2" > hello2.txt
$ tar -cvzf hello.tgz hello[12].txt
hello1.txt
hello2.txt
$ rm hello[12].txt
$ ls hello*
hello.tgz
$ tar -xvzf hello.tgz -O
hello1.txt
hello1
hello2.txt
hello2
$ ls hello*
hello.tgz
$ tar -xvzf hello.tgz
hello1.txt
hello2.txt
$ ls hello*
hello1.txt  hello2.txt  hello.tgz
$ rm hello*

Note that -regex depends on whole path.

 -regex pattern
              File name matches regular expression pattern.  
              This is a match on the whole path, not a search.

You don't actually have to use -regex for what you are doing.

find . -iname "*[0-9]"

By the way, Jsoup has method that takes file: http://jsoup.org/apidocs/org/jsoup/Jsoup.html#parse(java.io.File,%20java.lang.String)

the declaration is generally the most 'useful', but that depends on how you want to use the class.

both is not valid.

You can this query:

pip install image 

I had pillow installed, and still, I got the error that you mentioned. But after I executed the above command, the error vanished. And My program worked perfectly.

//////////////////////////////////////////////////////
function ToInt(x){x=parseInt(x);return isNaN(x)?0:x;}
//////////////////////////////////////////////////////
var x = ToInt('');   //->  x=0
    x = ToInt('abc') //->  x=0
    x = ToInt('0.1') //->  x=0
    x = ToInt('5.9') //->  x=5
    x = ToInt(5.9)   //->  x=5
    x = ToInt(5)     //->  x=5

for 2021 this one worked for me

brew tap homebrew/cask-versions


brew install --cask adoptopenjdk8

var outputString = String.Join("", inputString.Where(Char.IsDigit));

Get all numbers in the string. So if you use for examaple '1 plus 2' it will get '12'.

<> will surely give you all values not equal to 5. If you have more than one record in table it will give you all except 5. If on the other hand you have only one, you will get surely one. Give the table schema so that one can help you properly

use this function http://www.codingforums.com/showthread.php?t=71882

function getDirectory( $path = '.', $level = 0 ){

$ignore = array( 'cgi-bin', '.', '..' ); 
// Directories to ignore when listing output. Many hosts 
// will deny PHP access to the cgi-bin. 

$dh = @opendir( $path ); 
// Open the directory to the handle $dh 

while( false !== ( $file = readdir( $dh ) ) ){ 
// Loop through the directory 

    if( !in_array( $file, $ignore ) ){ 
    // Check that this file is not to be ignored 

        $spaces = str_repeat( ' ', ( $level * 4 ) ); 
        // Just to add spacing to the list, to better 
        // show the directory tree. 

        if( is_dir( "$path/$file" ) ){ 
        // Its a directory, so we need to keep reading down... 

            echo "<strong>$spaces $file</strong><br />"; 
            getDirectory( "$path/$file", ($level+1) ); 
            // Re-call this same function but on a new directory. 
            // this is what makes function recursive. 

        } else { 

            echo "$spaces $file<br />"; 
            // Just print out the filename 

        } 

    } 

} 

closedir( $dh ); 
// Close the directory handle 
}

and call the function like that

getDirectory( "." ); 
// Get the current directory 

getDirectory( "./files/includes" ); 
// Get contents of the "files/includes" folder 

Keeping your commands short will make them easier to remember:

git log --graph --oneline

I don't have enough reputation to add comment, so I posted this as an answer. But for original issue with this command:

@echo off
FOR %%p IN (C:\Users\vexe\Pictures\sample) DO FOR %%t IN (*.jpg) DO del /s %%p\%%t

The first For is lacking recursive syntax, it should be:

@echo off
FOR /R %%p IN (C:\Users\vexe\Pictures\sample) DO FOR %%t IN (*.jpg) DO del /s %%p\%%t

You can just do:

FOR %%p IN (C:\Users\0300092544\Downloads\Ces_Sce_600) DO @ECHO %%p

to show the actual output.

Other solution is:

public static T Deserialize<T>(string rawXml)
{
    using (XmlReader reader = XmlReader.Create(new StringReader(rawXml)))
    {
        DataContractSerializer formatter0 = 
            new DataContractSerializer(typeof(T));
        return (T)formatter0.ReadObject(reader);
    }
}

One remark: sometimes it happens that raw xml contains e.g.:

<?xml version="1.0" encoding="utf-16"?>

then of course you can't use UTF8 encoding used in other examples..

If you are using Android Lollipop i.e. SDK 21, then:

CookieManager.getInstance().setAcceptCookie(true);

won't work. You need to use:

CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);

I ran into same issue and the above line worked as a charm.

 jquery.ajax({
            url: `//your api url`
            type: "GET",
            dataType: "json",
            success: function(data) {
                jQuery.each(data, function(index, value) {
                        console.log(data);
                        `All you API data is here`
                    }
                }
            });     

The ScriptIgnoreAttribute class is in the System.Web.Extensions.dll assembly (Located under Assemblies > Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project.

You can find this information at top of the MSDN page for the ScriptIgnoreAttribute class.

Right now i am developing using System.Data.SQlite NuGet package (version 1.0.109.2). Which using SQLite version 3.24.0.

And this works for me.

SELECT * FROM tables WHERE datetime 
BETWEEN '2018-10-01 00:00:00' AND '2018-10-10 23:59:59';

I don't net to use the datetime() function. Perhaps they already updated the SQL query on that SQLite version.

As is defined in RFC 1341:

In the Extended BNF notation of RFC 822, a Content-Type header field value is defined as follows:

Content-Type := type "/" subtype *[";" parameter]

type := "application" / "audio" / "image" / "message" / "multipart" / "text" / "video" / x-token

x-token := < The two characters "X-" followed, with no intervening white space, by any token >

subtype := token

parameter := attribute "=" value

attribute := token

value := token / quoted-string

token := 1*

tspecials := "(" / ")" / "<" / ">" / "@" ; Must be in / "," / ";" / ":" / "\" / <"> ; quoted-string, / "/" / "[" / "]" / "?" / "." ; to use within / "=" ; parameter values

And a list of known MIME types that can follow it (or, as Joe remarks, the IANA source).

As you can see the list is way too big for you to validate against all of them. What you can do is validate against the general format and the type attribute to make sure that is correct (the set of options is small) and just assume that what follows it is correct (and of course catch any exceptions you might encounter when you put it to actual use).

Also note the comment above:

If another primary type is to be used for any reason, it must be given a name starting with "X-" to indicate its non-standard status and to avoid any potential conflict with a future official name.

You'll notice that a lot of HTTP requests/responses include an X- header of some sort which are self defined, keep this in mind when validating the types.

If you're dealing with Data Validation lists, you can use the Worksheet_Change event. Right click on the sheet with the data validation and choose View Code. Then type in this:

Private Sub Worksheet_Change(ByVal Target As Range)

    MsgBox Target.Value

End Sub

If you're dealing with ActiveX comboboxes, it's a little more complicated. You need to create a custom class module to hook up the events. First, create a class module named CComboEvent and put this code in it.

Public WithEvents Cbx As MSForms.ComboBox

Private Sub Cbx_Change()

    MsgBox Cbx.Value

End Sub

Next, create another class module named CComboEvents. This will hold all of our CComboEvent instances and keep them in scope. Put this code in CComboEvents.

Private mcolComboEvents As Collection

Private Sub Class_Initialize()
    Set mcolComboEvents = New Collection
End Sub

Private Sub Class_Terminate()
    Set mcolComboEvents = Nothing
End Sub

Public Sub Add(clsComboEvent As CComboEvent)

    mcolComboEvents.Add clsComboEvent, clsComboEvent.Cbx.Name

End Sub

Finally, create a standard module (not a class module). You'll need code to put all of your comboboxes into the class modules. You might put this in an Auto_Open procedure so it happens whenever the workbook is opened, but that's up to you.

You'll need a Public variable to hold an instance of CComboEvents. Making it Public will kepp it, and all of its children, in scope. You need them in scope so that the events are triggered. In the procedure, loop through all of the comboboxes, creating a new CComboEvent instance for each one, and adding that to CComboEvents.

Public gclsComboEvents As CComboEvents

Public Sub AddCombox()

    Dim oleo As OLEObject
    Dim clsComboEvent As CComboEvent

    Set gclsComboEvents = New CComboEvents

    For Each oleo In Sheet1.OLEObjects
        If TypeName(oleo.Object) = "ComboBox" Then
            Set clsComboEvent = New CComboEvent
            Set clsComboEvent.Cbx = oleo.Object
            gclsComboEvents.Add clsComboEvent
        End If
    Next oleo

End Sub

Now, whenever a combobox is changed, the event will fire and, in this example, a message box will show.

You can see an example at https://www.dropbox.com/s/sfj4kyzolfy03qe/ComboboxEvents.xlsm

It worth mentioning that the build time will be increased for VS 2015 users after:

Install-Package Microsoft.Net.Compilers

Those who are using VS 2015 and have to keep this package in their projects can fix increased build time.

Edit file packages\Microsoft.Net.Compilers.1.2.2\build\Microsoft.Net.Compilers.props and clean it up. The file should look like:

<Project DefaultTargets="Build" 
         xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
</Project>

Doing so forces a project to be built as it was before adding Microsoft.Net.Compilers package

Or try an alternate method using Time datatype:

DECLARE @MyTime TIME = '03:30:00', @MyDay DATETIME = CAST(GETDATE() AS DATE)

SELECT @MyDay+@MyTime

min sort:

#!/bin/bash
array=(.....)
index_of_element1=0

while (( ${index_of_element1} < ${#array[@]} )); do

    element_1="${array[${index_of_element1}]}"

    index_of_element2=$((index_of_element1 + 1))
    index_of_min=${index_of_element1}

    min_element="${element_1}"

        for element_2 in "${array[@]:$((index_of_element1 + 1))}"; do
            min_element="`printf "%s\n%s" "${min_element}" "${element_2}" | sort | head -n+1`"      
            if [[ "${min_element}" == "${element_2}" ]]; then
                index_of_min=${index_of_element2}
            fi
            let index_of_element2++
        done

        array[${index_of_element1}]="${min_element}"
        array[${index_of_min}]="${element_1}"

    let index_of_element1++
done

It's ctrl + . when, for example, you try to type List you need to type < at the end and press ctrl + . for it to work.

Another way that the one described by danield is to have a child container width display inline, and the tipography color you want. The parent element width the text-decoration, and the color of underline you want. Like this:

div{text-decoration:underline;color:#ff0000;display:inline-block;width:50px}_x000D_
div span{color:#000;display:inline}

<div>_x000D_
  <span>Hover me, i can have many lines</span>_x000D_
</div>

use git pull:

git pull origin yourbranch

TLDR: Check that you don't connect to the same table/view twice.

FooConfiguration.cs    
builder.ToTable("Profiles", "dbo");
...

BarConfiguration.cs
builder.ToTable("profiles", "dbo");

For me the issue was that I was trying to add an entity that connected to the same table as some other entity that already existed.

I added a new DbSet with entity and config, thinking we don't have it in our solution yet, however after searching for table name through all solution I found another place where we already connected to it.

Switching to use existing DbSet and removing my newly added one solved the issue.

$('#yourid').prop('disabled', true);

I have gone through the folder structure with a tool called BareGrep to ensure I have got all of the namespace changes. Its a free tool that will allow you to search over the files in a specified file structure.

The data.table package provides the function DT[sample(.N, M)], sampling M random rows from the data table DT.

library(data.table)
set.seed(10)

mtcars <- data.table(mtcars)
mtcars[sample(.N, 6)]

    mpg cyl  disp  hp drat    wt  qsec vs am gear carb

You could just use: {in and out function callback}

$(".result").hover(function () {
    $(this).toggleClass("result_hover");
 });

For your example, better will be to use CSS pseudo class :hover: {no js/jquery needed}

.result {
    height: 72px;
    width: 100%;
    border: 1px solid #000;
  }
  .result:hover {
    background-color: #000;
  }

If you want to save the model and wants to resume the training later:

Single GPU: Save:

state = {
        'epoch': epoch,
        'state_dict': model.state_dict(),
        'optimizer': optimizer.state_dict(),
}
savepath='checkpoint.t7'
torch.save(state,savepath)

Load:

checkpoint = torch.load('checkpoint.t7')
model.load_state_dict(checkpoint['state_dict'])
optimizer.load_state_dict(checkpoint['optimizer'])
epoch = checkpoint['epoch']

Multiple GPU: Save

state = {
        'epoch': epoch,
        'state_dict': model.module.state_dict(),
        'optimizer': optimizer.state_dict(),
}
savepath='checkpoint.t7'
torch.save(state,savepath)

Load:

checkpoint = torch.load('checkpoint.t7')
model.load_state_dict(checkpoint['state_dict'])
optimizer.load_state_dict(checkpoint['optimizer'])
epoch = checkpoint['epoch']

#Don't call DataParallel before loading the model otherwise you will get an error

model = nn.DataParallel(model) #ignore the line if you want to load on Single GPU

You need to load jquery first before bootstrap.

require.config({
    paths: {
        jquery: 'libs/jquery/jquery',
        underscore: 'libs/underscore/underscore',
        backbone: 'libs/backbone/backbone',
        bootstrap: 'libs/bootstrap',
        jquerytablesorter: 'libs/tablesorter/jquery.tablesorter',
        tablesorter: 'libs/tablesorter/tables',
        ajaxupload: 'libs/ajax-upload',
        templates: '../templates'
    },
    shim: {
        'backbone': {
            deps: ['underscore', 'jquery'],
            exports: 'Backbone'
        },
        'jquery': {
            exports: '$'
        },
        'bootstrap': {
            deps: ['jquery'],
            exports: '$'
        },
        'jquerytablesorter': {
            deps: ['jquery'],
            exports: '$'
        },
        'tablesorter': {
            deps: ['jquery'],
            exports: '$'
        },
        'ajaxupload': {
            deps: ['jquery'],
            exports: '$'
        },
        'underscore': {
            exports: '_'
        },
    }
});
require(['app', ], function(App) {
    App.initialize();
});

Works like charm! quick and easy fix.

In my situation, I didn't have the full vendor dependencies in place (composer file was messed up during original install) - so running any artisan commands caused a failure.

I was able to use the --no-scripts flag to prevent artisan from executing before it was included. Once my dependencies were in place, everything worked as expected.

composer update --no-scripts

The problem is that the else and if are two operators here. Since you open a new 'if' you need a corresponding 'end if'.

Thus:

declare
mark number :=50;
begin
  mark :=& mark;
  if (mark between 85 and 100) then
    dbms_output.put_line('mark is A ');
  else 
    if (mark between 50 and 65) then
      dbms_output.put_line('mark is D ');
    else 
      if (mark between 66 and 75) then
        dbms_output.put_line('mark is C ');
      else 
        if (mark between 76 and 84) then
          dbms_output.put_line('mark is B');
        else 
          dbms_output.put_line('mark is F');
        end if;
      end if;
    end if;
  end if;
end;
/

Alternatively you can use elsif:

declare
mark number :=50;
begin
  mark :=& mark;
  if (mark between 85 and 100)
    then
    dbms_output.put_line('mark is A ');
  elsif (mark between 50 and 65) then
    dbms_output.put_line('mark is D ');
  elsif (mark between 66 and 75) then
    dbms_output.put_line('mark is C ');
  elsif (mark between 76 and 84) then
    dbms_output.put_line('mark is B');
  else 
    dbms_output.put_line('mark is F');
  end if;
end;
/

Did you override the run() method? If you overrided __init__, did you make sure to call the base threading.Thread.__init__()?

After starting the two threads, does the main thread continue to do work indefinitely/block/join on the child threads so that main thread execution does not end before the child threads complete their tasks?

And finally, are you getting any unhandled exceptions?

I'd just like to add to the very helpful answer from Kurt Pfeifle - there is now a Python wrapper for Tabula, and this seems to work very well so far: https://github.com/chezou/tabula-py

This will convert your PDF table to a Pandas data frame. You can also set the area in x,y co-ordinates which is obviously very handy for irregular data.

HTML

<input [(ngModel)] = "searchTerm" (ngModelChange) = "search()"/>
<div *ngFor = "let item of items">{{item.name}}</div>

Component

search(): void {
    let term = this.searchTerm;
    this.items = this.itemsCopy.filter(function(tag) {
        return tag.name.indexOf(term) >= 0;
    }); 
}

Note that this.itemsCopy is equal to this.items and should be set before doing the search.

There is no limit. It only depends on your free memory and system maximum file size. But that doesn't mean you shouldn't take precautionary measure in tackling memory usage in your database. Always create a script that can delete rows that are out of use or that will keep total no of rows within a particular figure, say a thousand.

We can do it by using the below code snippet..

Angular Code:

 export class AppComponent {  
    toggleShowHide: string = "visible";  
 }

HTML Template:

  Enter text to hide or show item in bellow: 
  <input type="text" [(ngModel)]="toggleShowHide">
  <br>
  Toggle Show/hide:
  <div [style.visibility]="toggleShowHide">   
     Final Release Angular 2!
  </div>

I know this is very old and possibly talking about an older version of Visual studio and so this might not have been an option before but anyway, my way would be when at a breakpoint use the locals window to see all current variable values ( Debug >> Windows >> Locals )

You can do the following:

TimeSpan duration = b - a;

There's plenty of built in methods in the timespan class to do what you need, i.e.

duration.TotalSeconds
duration.TotalMinutes

More info can be found here.

"If you start an android Service with startService(..) that Service will remain running until you explicitly invoke stopService(..). There are two reasons that a service can be run by the system. If someone calls Context.startService() then the system will retrieve the service (creating it and calling its onCreate() method if needed) and then call its onStartCommand(Intent, int, int) method with the arguments supplied by the client. The service will at this point continue running until Context.stopService() or stopSelf() is called. Note that multiple calls to Context.startService() do not nest (though they do result in multiple corresponding calls to onStartCommand()), so no matter how many times it is started a service will be stopped once Context.stopService() or stopSelf() is called; however, services can use their stopSelf(int) method to ensure the service is not stopped until started intents have been processed.

Clients can also use Context.bindService() to obtain a persistent connection to a service. This likewise creates the service if it is not already running (calling onCreate() while doing so), but does not call onStartCommand(). The client will receive the IBinder object that the service returns from its onBind(Intent) method, allowing the client to then make calls back to the service. The service will remain running as long as the connection is established (whether or not the client retains a reference on the Service's IBinder). Usually the IBinder returned is for a complex interface that has been written in AIDL.

A service can be both started and have connections bound to it. In such a case, the system will keep the service running as long as either it is started or there are one or more connections to it with the Context.BIND_AUTO_CREATE flag. Once neither of these situations hold, the Service's onDestroy() method is called and the service is effectively terminated. All cleanup (stopping threads, unregistering receivers) should be complete upon returning from onDestroy()."

Use the collapse argument to paste:

paste(a,collapse=" ")
[1] "aa bb cc"

in my case, some characters like " , :"'{}[] " maybe corrupt the JSON format, so use try json.loads(str) except to check your input

This works for uppercase and lowercase. I don't know how elegant you deem it to be.

def rot13(s):
    rot=lambda x:chr(ord(x)+13) if chr(ord(x.lower())+13).isalpha()==True else chr(ord(x)-13)
    s=[rot(i) for i in filter(lambda x:x!=',',map(str,s))]
    return ''.join(s)

To extend what Rahul Gupta said:

You can use Java function int random = Random.nextInt(n).
This returns a random int in the range [0, n-1].

I.e., to get the range [20, 80] use:

final int random = new Random().nextInt(61) + 20; // [0, 60] + 20 => [20, 80]

To generalize more:

final int min = 20;
final int max = 80;
final int random = new Random().nextInt((max - min) + 1) + min;

What you wrote would get you the greatest id assuming they were unique and auto-incremented that would be fine assuming you are okay with inviting concurrency issues.
Since you're using MySQL as your database, there is the specific function LAST_INSERT_ID() which only works on the current connection that did the insert.
PHP offers a specific function for that too called mysql_insert_id.

Compiling with -source 1.5 -target 1.5 (in a JDK 6 environment) will honor only language elements that were in 1.5 and prior. Great. But there were no language changes in 6 anyway. Problem with this approach (on Mac with 1.6) is that using classes that came AFTER 1.5 will still compile because they exist in the rt.jar. So one could run in a 1.5 env and get a class not found exception with no prior warning when compiling. I found this out the hard way with javax.swing.event.RowSorterEvent/Listener. Both entered "Since 1.6" but are not caught with -source 1.5

Try to use this one

var result= stringToReplace.replace(/[^\w\s]/g, '')

[^] is for negation, \w for [a-zA-Z0-9_] word characters and \s for space, /[]/g for global

This is years later, working on a legacy site... For the life of me I couldn't get the ->andWhere() or ->expr()->in() solutions working.

Finally looked in the Doctrine mongodb-odb repo and found some very revealing tests:

public function testQueryWhereIn()
{ 
  $qb = $this->dm->createQueryBuilder('Documents\User');
  $choices = array('a', 'b');
  $qb->field('username')->in($choices);
  $expected = [
    'username' => ['$in' => $choices],
  ];
  $this->assertSame($expected, $qb->getQueryArray());
}

It worked for me!

You can find the tests on github here. Useful for clarifying all sorts of nonsense.

Note: My setup is using Doctrine MongoDb ODM v1.0.dev as far as i can make out.

For-loops:

For-loop in C:

for(int x = 0; x<=3; x++)
{
    //Do something!
}

The same loop in 8086 assembler:

        xor cx,cx   ; cx-register is the counter, set to 0
loop1   nop         ; Whatever you wanna do goes here, should not change cx
        inc cx      ; Increment
        cmp cx,3    ; Compare cx to the limit
        jle loop1   ; Loop while less or equal

That is the loop if you need to access your index (cx). If you just wanna to something 0-3=4 times but you do not need the index, this would be easier:

        mov cx,4    ; 4 iterations
loop1   nop         ; Whatever you wanna do goes here, should not change cx
        loop loop1  ; loop instruction decrements cx and jumps to label if not 0

If you just want to perform a very simple instruction a constant amount of times, you could also use an assembler-directive which will just hardcore that instruction

times 4 nop

Do-while-loops

Do-while-loop in C:

int x=1;
do{
    //Do something!
}
while(x==1)

The same loop in assembler:

        mov ax,1
loop1   nop         ; Whatever you wanna do goes here
        cmp ax,1    ; Check wether cx is 1
        je loop1    ; And loop if equal

While-loops

While-loop in C:

while(x==1){
    //Do something
}

The same loop in assembler:

        jmp loop1   ; Jump to condition first
cloop1  nop         ; Execute the content of the loop
loop1   cmp ax,1    ; Check the condition
        je cloop1   ; Jump to content of the loop if met

For the for-loops you should take the cx-register because it is pretty much standard. For the other loop conditions you can take a register of your liking. Of course replace the no-operation instruction with all the instructions you wanna perform in the loop.

To pass the ellipses on, you have to convert them to a va_list and use that va_list in your second function. Specifically;

void format_string(char *fmt,va_list argptr, char *formatted_string);


void debug_print(int dbg_lvl, char *fmt, ...) 
{    
 char formatted_string[MAX_FMT_SIZE];

 va_list argptr;
 va_start(argptr,fmt);
 format_string(fmt, argptr, formatted_string);
 va_end(argptr);
 fprintf(stdout, "%s",formatted_string);
}

Take advantage of the standard char_traits. Recall that a std::string is in fact a typedef for std::basic_string<char>, or more explicitly, std::basic_string<char, std::char_traits<char> >. The char_traits type describes how characters compare, how they copy, how they cast etc. All you need to do is typedef a new string over basic_string, and provide it with your own custom char_traits that compare case insensitively.

struct ci_char_traits : public char_traits<char> {
    static bool eq(char c1, char c2) { return toupper(c1) == toupper(c2); }
    static bool ne(char c1, char c2) { return toupper(c1) != toupper(c2); }
    static bool lt(char c1, char c2) { return toupper(c1) <  toupper(c2); }
    static int compare(const char* s1, const char* s2, size_t n) {
        while( n-- != 0 ) {
            if( toupper(*s1) < toupper(*s2) ) return -1;
            if( toupper(*s1) > toupper(*s2) ) return 1;
            ++s1; ++s2;
        }
        return 0;
    }
    static const char* find(const char* s, int n, char a) {
        while( n-- > 0 && toupper(*s) != toupper(a) ) {
            ++s;
        }
        return s;
    }
};

typedef std::basic_string<char, ci_char_traits> ci_string;

You can do:

ssh user@host 'bash -s' < /path/script.sh

The default solution is to install KB2999226 of Microsoft.

I have put this in my partial view:

@HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString()

in the same kind of situation you describe, and it shows the controller described in the URL (Category for you, Product for me), instead of the actual location of the partial view.

So use this alert instead:

alert('@HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString()');

From the JDK source:

static <T> Function<T, T> identity() {
    return t -> t;
}

So, no, as long as it is syntactically correct.

Use this script: https://github.com/ricardobranco777/docker-volumes.sh

This does preserve data in volumes.

Example usage:

# Stop the container   
docker stop $CONTAINER

# Create a new image   
docker commit $CONTAINER $CONTAINER

# Save image
docker save -o $CONTAINER.tar $CONTAINER

# Save the volumes (use ".tar.gz" if you want compression)
docker-volumes.sh $CONTAINER save $CONTAINER-volumes.tar

# Copy image and volumes to another host
scp $CONTAINER.tar $CONTAINER-volumes.tar $USER@$HOST:

# On the other host:
docker load -i $CONTAINER.tar
docker create --name $CONTAINER [<PREVIOUS CONTAINER OPTIONS>] $CONTAINER

# Load the volumes
docker-volumes.sh $CONTAINER load $CONTAINER-volumes.tar

# Start container
docker start $CONTAINER

Create A Shortcut That Opens The Command Prompt & Runs A Command:

Yes! You can create a shortcut to cmd.exe with a command specified after it. Alternatively you could create a batch script, if your goal is just to have a clickable way to run commands.

Steps:

1. Right click on some empty space in Explorer, and in the context menu go to "New/Shortcut".

2. When prompted to enter a location put either:

"C:\Windows\System32\cmd.exe /k your-command" This will run the command and keep (/k) the command prompt open after.

or

"C:\Windows\System32\cmd.exe /c your-command" This will run the command and the close (/c) the command prompt.

Notes:

• Tested, and working on Windows 8 - Core X86-64 September 12 2014

• If you want to have more than one command, place an "&" symbol in between them. For example: "C:\Windows\System32\cmd.exe /k command1 & command2".

Integer.parseInt(hex,16);    
System.out.print(Integer.toBinaryString(hex));

Parse hex(String) to integer with base 16 then convert it to Binary String using toBinaryString(int) method

example

int num = (Integer.parseInt("A2B", 16));
System.out.print(Integer.toBinaryString(num));

Will Print

101000101011

Max Hex vakue Handled by int is FFFFFFF

i.e. if FFFFFFF0 is passed ti will give error

I think of it as a large array of binary data. The usability of BLOB follows immediately from the limited bandwidth of the DB interface, it is not determined by the DB storage mechanisms. No matter how you store the large piece of data, the only way to store and retrieve is the narrow database interface. The database is a bottleneck of the system. Why to use it as a file server, which can easily be distributed? Normally you do not want to download the BLOB. You just want the DB to store your BLOB urls. Deposite the BLOBs on a separate file server. Then, you reliefe the precious DB connection and provide unlimited bandwidth for large objects. This creates some issue of coherence though.

For those who still have problems after attempting the suggestions above: I solved the issue by updating the maven project.

A standard solution for this problem is to allow slashes by making the parameter that may contain slashes the last parameter in the url.

For a product code url you would then have...

mysite.com/product/details/PR12345/22

For a search term you'd have

http://project/search_exam/0/search_subject/0/keyword/Psychology/Management

(The keyword here is Psychology/Management)

It's not a massive amount of work to process the first "named" parameters then concat the remaining ones to be product code or keyword.

Some frameworks have this facility built in to their routing definitions.

This is not applicable to use case involving two parameters that my contain slashes.

It is really simple, there are just some syntax you have to keep in mind.

Arrays.sort(contests, (a, b) -> Integer.compare(a[0],b[0]));//increasing order ---1

Arrays.sort(contests, (b, a) -> Integer.compare(b[0],a[0]));//increasing order ---2

Arrays.sort(contests, (a, b) -> Integer.compare(b[0],a[0]));//decreasing order ---3

Arrays.sort(contests, (b, a) -> Integer.compare(a[0],b[0]));//decreasing order ---4

If you notice carefully, then it's the change in the order of 'a' and 'b' that affects the result. For line 1, the set is of (a,b) and Integer.compare(a[0],b[0]), so it is increasing order. Now if we change the order of a and b in any one of them, suppose the set of (a,b) and Integer.compare(b[0],a[0]) as in line 3, we get decreasing order.

Best and Free ( maybe only) solution for this is google sheets. i don't know whether it plots as u expected or not but certainly you can draw multiple axes.

All commands must be executed while connected to the right database in the right database cluster. Make sure of it.

The user needs access to the database, obviously:

GRANT CONNECT ON DATABASE my_db TO my_user;

And (at least) the USAGE privilege on the schema:

GRANT USAGE ON SCHEMA public TO my_user;

Or grant USAGE on all custom schemas:

DO
$$
BEGIN
   -- RAISE NOTICE '%', (  -- use instead of EXECUTE to see generated commands
   EXECUTE (
   SELECT string_agg(format('GRANT USAGE ON SCHEMA %I TO my_user', nspname), '; ')
   FROM   pg_namespace
   WHERE  nspname <> 'information_schema' -- exclude information schema and ...
   AND    nspname NOT LIKE 'pg\_%'        -- ... system schemas
   );
END
$$;

Then, all permissions for all tables (requires Postgres 9.0 or later).
And don't forget sequences (if any):

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO my_user;
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO my_user;

For older versions you could use the "Grant Wizard" of pgAdmin III (the default GUI).

There are some other objects, the manual for GRANT has the complete list as of Postgres 12:

privileges on a database object (table, column, view, foreign table, sequence, database, foreign-data wrapper, foreign server, function, procedure, procedural language, schema, or tablespace)

But the rest is rarely needed. More details:

• How to manage DEFAULT PRIVILEGES for USERs on a DATABASE vs SCHEMA?
• Grant privileges for a particular database in PostgreSQL
• How to grant all privileges on views to arbitrary user

Consider upgrading to a current version.

If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.

I would recommend looking at the numpy broadcasting rules.

This is the way you should be doing it, and I say this because you are clearly new to C# and should probably try to understand how some basic stuff works!

public int Sum(params int[] customerssalary)
{
   int result = 0;

   for(int i = 0; i < customerssalary.Length; i++)
   {
      result += customerssalary[i];
   }

   return result;
}

with this Sum function, you can use this to calculate the average too...

public decimal Average(params int[] customerssalary)
{
   int sum = Sum(customerssalary);
   decimal result = (decimal)sum / customerssalary.Length;
   return result;
}

the reason for using a decimal type in the second function is because the division can easily return a non-integer result

Others have provided a Linq alternative which is what I would use myself anyway, but with Linq there is no point in having your own functions anyway. I have made the assumption that you have been asked to implement such functions as a task to demonstrate your understanding of C#, but I could be wrong.

ok, here is what i understood from your question. You are writing a csv file from python but when you are opening that file into some other application like excel or open office they are showing the complete row in one cell rather than each word in individual cell. I am right??

if i am then please try this,

import csv

with open(r"C:\\test.csv", "wb") as csv_file:
    writer = csv.writer(csv_file, delimiter =",",quoting=csv.QUOTE_MINIMAL)
    writer.writerow(["a","b"])

you have to set the delimiter = ","

You can add .a file in the linking command:

  gcc yourfiles /path/to/library/libLIBRARY.a

But this is not talking with gcc driver, but with ld linker as options like -Wl,anything are.

When you tell gcc or ld -Ldir -lLIBRARY, linker will check both static and dynamic versions of library (you can see a process with -Wl,--verbose). To change order of library types checked you can use -Wl,-Bstatic and -Wl,-Bdynamic. Here is a man page of gnu LD: http://linux.die.net/man/1/ld

To link your program with lib1, lib3 dynamically and lib2 statically, use such gcc call:

gcc program.o -llib1 -Wl,-Bstatic -llib2 -Wl,-Bdynamic -llib3

Assuming that default setting of ld is to use dynamic libraries (it is on Linux).

Here's another option for those not using heatmap.2 (aheatmap is good!)

Make a sequential vector of 100 values from min to max of your input matrix, find value closest to 0 in that, make two vector of colours to and from desired midpoint, combine and use them:

breaks <- seq(from=min(range(inputMatrix)), to=max(range(inputMatrix)), length.out=100)
midpoint <- which.min(abs(breaks - 0))
rampCol1 <- colorRampPalette(c("forestgreen", "darkgreen", "black"))(midpoint)
rampCol2 <- colorRampPalette(c("black", "darkred", "red"))(100-(midpoint+1))
rampCols <- c(rampCol1,rampCol2)

Why don't you just write a simple utility method:

public final class DateUtils {
    private DateUtils() {
    }

    public static Calendar calendarFor(int year, int month, int day) {
        Calendar cal = Calendar.getInstance();
        cal.set(Calendar.YEAR, year);
        cal.set(Calendar.MONTH, month);
        cal.set(Calendar.DAY_OF_MONTH, day);
        return cal;
    }

    // ... maybe other utility methods
}

And then call that everywhere in the rest of your code:

Calendar cal = DateUtils.calendarFor(2010, Calendar.MAY, 21);

This is just an indentation problem since Python is very strict when it comes to it.

If you are using Sublime, you can select all, click on the lower right beside 'Python' and make sure you check 'Indent using spaces' and choose your Tab Width to be consistent, then Convert Indentation to Spaces to convert all tabs to spaces.

Many of these answers deal with casting from one type to another. I get the most use from unions with the same types just more of them (ie when parsing a serial data stream). They allow the parsing / construction of a framed packet to become trivial.

typedef union
{
    UINT8 buffer[PACKET_SIZE]; // Where the packet size is large enough for
                               // the entire set of fields (including the payload)

    struct
    {
        UINT8 size;
        UINT8 cmd;
        UINT8 payload[PAYLOAD_SIZE];
        UINT8 crc;
    } fields;

}PACKET_T;

// This should be called every time a new byte of data is ready 
// and point to the packet's buffer:
// packet_builder(packet.buffer, new_data);

void packet_builder(UINT8* buffer, UINT8 data)
{
    static UINT8 received_bytes = 0;

    // All range checking etc removed for brevity

    buffer[received_bytes] = data;
    received_bytes++;

    // Using the struc only way adds lots of logic that relates "byte 0" to size
    // "byte 1" to cmd, etc...
}

void packet_handler(PACKET_T* packet)
{
    // Process the fields in a readable manner
    if(packet->fields.size > TOO_BIG)
    {
        // handle error...
    }

    if(packet->fields.cmd == CMD_X)
    {
        // do stuff..
    }
}

Edit The comment about endianness and struct padding are valid, and great, concerns. I have used this body of code almost entirely in embedded software, most of which I had control of both ends of the pipe.

I would use the translate method without translation table. It deletes the letters in second argument in recent Python versions.

def remove_chars(line):
    line7=line[7].translate(None,'abcd')
    return line[:7]+[line7]+line[8:]

line= ['ad','da','sdf','asd',
        '3424','342sfas','asdfaf','sdfa',
        'afase']
print line[7]
line = remove_chars(line)
print line[7]

You have to just add the index_col=False parameter

df1 = pd.read_csv('foo.csv',
     header=0,
     index_col=False,
     names=["dummy", "date", "loc", "x"], 
     usecols=["dummy", "date", "loc", "x"],
     parse_dates=["date"])
  print df1

This will install jdk for you and check for the jarsigner inside it

sudo apt install -y default-jdk

to find jarsigner you can use whereis jarsigner

first of all;

a Fragment must be inside a FragmentActivity, that's the first rule,

a FragmentActivity is quite similar to a standart Activity that you already know, besides having some Fragment oriented methods

second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView, where you inflate your layout, think of it as the setContentLayout

here is an example:

    @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     mView       = inflater.inflate(R.layout.fragment_layout, container, false);       return mView; } 

and continu your work based on that mView, so to find a View by id, call mView.findViewById(..);

for the FragmentActivity part:

the xml part "must" have a FrameLayout in order to inflate a fragment in it

        <FrameLayout             android:id="@+id/content_frame"             android:layout_width="match_parent"             android:layout_height="match_parent"  >         </FrameLayout> 

as for the inflation part

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();

begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site

Problem solved, I've not added the index.html. Which is point out in the web.xml

Note: a project may have more than one web.xml file.

if there are another web.xml in

Then you might need to add another index (this time index.jsp) to

src/main/webapp/WEB-INF/pages/

The 'V' of HSV is probably what you're looking for. MATLAB has an rgb2hsv function and the previously cited wikipedia article is full of pseudocode. If an RGB2HSV conversion is not feasible, a less accurate model would be the grayscale version of the image.

Here is a concise way using lambdas and JDK 8 Supplier to fit everything in the outer try:

try (Connection con = DriverManager.getConnection(JDBC_URL, prop);
    PreparedStatement stmt = ((Supplier<PreparedStatement>)() -> {
    try {
        PreparedStatement s = con.prepareStatement("SELECT userid, name, features FROM users WHERE userid = ?");
        s.setInt(1, userid);
        return s;
    } catch (SQLException e) { throw new RuntimeException(e); }
    }).get();
    ResultSet resultSet = stmt.executeQuery()) {
}

I assume entropy was mentioned in the context of building decision trees.

To illustrate, imagine the task of learning to classify first-names into male/female groups. That is given a list of names each labeled with either m or f, we want to learn a model that fits the data and can be used to predict the gender of a new unseen first-name.

name       gender
-----------------        Now we want to predict 
Ashley        f              the gender of "Amro" (my name)
Brian         m
Caroline      f
David         m

First step is deciding what features of the data are relevant to the target class we want to predict. Some example features include: first/last letter, length, number of vowels, does it end with a vowel, etc.. So after feature extraction, our data looks like:

# name    ends-vowel  num-vowels   length   gender
# ------------------------------------------------
Ashley        1         3           6        f
Brian         0         2           5        m
Caroline      1         4           8        f
David         0         2           5        m

The goal is to build a decision tree. An example of a tree would be:

length<7
|   num-vowels<3: male
|   num-vowels>=3
|   |   ends-vowel=1: female
|   |   ends-vowel=0: male
length>=7
|   length=5: male

basically each node represent a test performed on a single attribute, and we go left or right depending on the result of the test. We keep traversing the tree until we reach a leaf node which contains the class prediction (m or f)

So if we run the name Amro down this tree, we start by testing "is the length<7?" and the answer is yes, so we go down that branch. Following the branch, the next test "is the number of vowels<3?" again evaluates to true. This leads to a leaf node labeled m, and thus the prediction is male (which I happen to be, so the tree predicted the outcome correctly).

The decision tree is built in a top-down fashion, but the question is how do you choose which attribute to split at each node? The answer is find the feature that best splits the target class into the purest possible children nodes (ie: nodes that don't contain a mix of both male and female, rather pure nodes with only one class).

This measure of purity is called the information. It represents the expected amount of information that would be needed to specify whether a new instance (first-name) should be classified male or female, given the example that reached the node. We calculate it based on the number of male and female classes at the node.

Entropy on the other hand is a measure of impurity (the opposite). It is defined for a binary class with values a/b as:

Entropy = - p(a)*log(p(a)) - p(b)*log(p(b))

This binary entropy function is depicted in the figure below (random variable can take one of two values). It reaches its maximum when the probability is p=1/2, meaning that p(X=a)=0.5 or similarlyp(X=b)=0.5 having a 50%/50% chance of being either a or b (uncertainty is at a maximum). The entropy function is at zero minimum when probability is p=1 or p=0 with complete certainty (p(X=a)=1 or p(X=a)=0 respectively, latter implies p(X=b)=1).

Of course the definition of entropy can be generalized for a discrete random variable X with N outcomes (not just two):

(the log in the formula is usually taken as the logarithm to the base 2)

Back to our task of name classification, lets look at an example. Imagine at some point during the process of constructing the tree, we were considering the following split:

     ends-vowel
      [9m,5f]          <--- the [..,..] notation represents the class
    /          \            distribution of instances that reached a node
   =1          =0
 -------     -------
 [3m,4f]     [6m,1f]

As you can see, before the split we had 9 males and 5 females, i.e. P(m)=9/14 and P(f)=5/14. According to the definition of entropy:

Entropy_before = - (5/14)*log2(5/14) - (9/14)*log2(9/14) = 0.9403

Next we compare it with the entropy computed after considering the split by looking at two child branches. In the left branch of ends-vowel=1, we have:

Entropy_left = - (3/7)*log2(3/7) - (4/7)*log2(4/7) = 0.9852

and the right branch of ends-vowel=0, we have:

Entropy_right = - (6/7)*log2(6/7) - (1/7)*log2(1/7) = 0.5917

We combine the left/right entropies using the number of instances down each branch as weight factor (7 instances went left, and 7 instances went right), and get the final entropy after the split:

Entropy_after = 7/14*Entropy_left + 7/14*Entropy_right = 0.7885

Now by comparing the entropy before and after the split, we obtain a measure of information gain, or how much information we gained by doing the split using that particular feature:

Information_Gain = Entropy_before - Entropy_after = 0.1518

You can interpret the above calculation as following: by doing the split with the end-vowels feature, we were able to reduce uncertainty in the sub-tree prediction outcome by a small amount of 0.1518 (measured in bits as units of information).

At each node of the tree, this calculation is performed for every feature, and the feature with the largest information gain is chosen for the split in a greedy manner (thus favoring features that produce pure splits with low uncertainty/entropy). This process is applied recursively from the root-node down, and stops when a leaf node contains instances all having the same class (no need to split it further).

Note that I skipped over some details which are beyond the scope of this post, including how to handle numeric features, missing values, overfitting and pruning trees, etc..

You are casting ClientID to char* causing the function to assume its a null terinated char array, which it is not.

from cplusplus.com :

string& append ( const char * s ); Appends a copy of the string formed by the null-terminated character sequence (C string) pointed by s. The length of this character sequence is determined by the first ocurrence of a null character (as determined by traits.length(s)).

The code posted in the question is obviously not a a complete example (it's not adding anything to the arraylist, it's not defining i anywhere).

First as others have said you need to understand the difference between primitive types and the class types that box them. E.g. Integer boxes int, Double boxes double, Long boxes long and so-on. Java automatically boxes and unboxes in various scenarios (it used to be you had to box and unbox manually with library calls but that was deemed an ugly PITA).

http://docs.oracle.com/javase/tutorial/java/data/autoboxing.html

You can mostly cast from one primitive type to another (the exception being boolean) but you can't do the same for boxed types. To convert one boxed type to another is a bit more complex. Especially if you don't know the box type in advance. Usually it will involve converting via one or more primitive types.

So the answer to your question depends on what is in your arraylist, if it's just objects of type Integer you can do.

sum = ((double)(int)marks.get(i));

The cast to int will behind the scenes first cast the result of marks.get to Integer, then it will unbox that integer. We then use another cast to convert the primitive int to a primitive double. Finally the result will be autoboxed back into a Double when it is assigned to the sum variable. (asside, it would probablly make more sense for sum to be of type double rather than Double in most cases).

If your arraylist contains a mixture of types but they all implement the Number interface (Integer, Short, Long, Float and Double all do but Character and Boolean do not) then you can do.

sum = ((Number)marks.get(i)).doubleValue();

If there are other types in the mix too then you might need to consider using the instanceof operator to identify them and take appropriate action.

Source (Py v2.7.3) for traceback.format_exception() and called/related functions helps greatly. Embarrassingly, I always forget to Read the Source. I only did so for this after searching for similar details in vain. A simple question, "How to recreate the same output as Python for an exception, with all the same details?" This would get anybody 90+% to whatever they're looking for. Frustrated, I came up with this example. I hope it helps others. (It sure helped me! ;-)

In specific answer to this query:

sys.exc_info()[0].__name__, os.path.basename(sys.exc_info()[2].tb_frame.f_code.co_filename), sys.exc_info()[2].tb_lineno

Use File.mkdirs().

Change Below line

if (str == null | str.length() == 0) {

into

if (str == null || str.isEmpty()) {

now your code will run corectlly. Make sure str.isEmpty() comes after str == null because calling isEmpty() on null will cause NullPointerException. Because of Java uses Short-circuit evaluation when str == null is true it will not evaluate str.isEmpty()

You can programatically change it by setting the system property:

public class App {

    public static void main(String[] args) {

        System.setProperty(org.slf4j.impl.SimpleLogger.DEFAULT_LOG_LEVEL_KEY, "TRACE");

        final org.slf4j.Logger log = LoggerFactory.getLogger(App.class);

        log.trace("trace");
        log.debug("debug");
        log.info("info");
        log.warn("warning");
        log.error("error");

    }
}

The log levels are ERROR > WARN > INFO > DEBUG > TRACE.

Please note that once the logger is created the log level can't be changed. If you need to dynamically change the logging level you might want to use log4j with SLF4J.

If you need it for OpenGL related stuff:

/* Compute the nearest power of 2 number that is 
 * less than or equal to the value passed in. 
 */
static GLuint 
nearestPower( GLuint value )
{
    int i = 1;

    if (value == 0) return -1;      /* Error! */
    for (;;) {
         if (value == 1) return i;
         else if (value == 3) return i*4;
         value >>= 1; i *= 2;
    }
}

Would this help?

final List<String> l = new ArrayList<String>();
for (int i = 0; i < 10; i++) l.add("Number " + i);
for (int i = 0; i < 10; i++) System.out.println(l.get(i));

Use this XPath expression:

/*/*/X/node()

This selects any node (element, text node, comment or processing instruction) that is a child of any X element that is a grand-child of the top element of the XML document.

To verify what is selected, here is this XSLT transformation that outputs exactly the selected nodes:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>
 <xsl:template match="/">
  <xsl:copy-of select="/*/*/X/node()"/>
 </xsl:template>
</xsl:stylesheet>

and it produces exactly the wanted, correct result:

   First Text Node #1            
    <y> Y can Have Child Nodes #                
        <child> deep to it </child>
    </y>            Second Text Node #2 
    <z />

Explanation:

1. As defined in the W3 XPath 1.0 Spec, "child::node() selects all the children of the context node, whatever their node type." This means that any element, text-node, comment-node and processing-instruction node children are selected by this node-test.

2. node() is an abbreviation of child::node() (because child:: is the primary axis and is used when no axis is explicitly specified).

If you want to get the navigationBar height only, it's simple:

extension UIViewController{
   var navigationBarHeight: CGFloat {
       return self.navigationController?.navigationBar.frame.height ?? 0.0
   }
}

However, if you need the height of top notch of iPhone you don't need to get the navigationBar height and add to it the statusBar height, you can simply call safeAreaInsets that's why exist.

self.view.safeAreaInsets.top

Before starting your download check your runtime permissions and if you don't have permission the request permissions like this method

requestStoragePermission()

private void requestStoragePermission(){
    if (ActivityCompat.shouldShowRequestPermissionRationale(this, 
                android.Manifest.permission.READ_EXTERNAL_STORAGE))
        {

        }

        ActivityCompat.requestPermissions(this, 
            new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
            STORAGE_PERMISSION_CODE);
}

@Override
public void onRequestPermissionsResult(int requestCode, 
                @NonNull String[] permissions, 
                @NonNull int[] grantResults) {

    if(requestCode == STORAGE_PERMISSION_CODE){
        if(grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
        }
        else{
            Toast.makeText(this,
                           "Oops you just denied the permission", 
                           Toast.LENGTH_LONG).show();
        }
    }
}

You could use toArray() to convert into an array of Objects followed by this method to convert the array of Objects into an array of Strings:

Object[] objectArray = lst.toArray();
String[] stringArray = Arrays.copyOf(objectArray, objectArray.length, String[].class);

The use of _New is useful when working on pages that are Iframed. Since target="_blank" doesn't do the trick and opens the page on the same iframe... target new is the best solution for Iframe Pages. Just my five cents.

I wrote up this handy function to find the mode.

def mode(nums):
    corresponding={}
    occurances=[]
    for i in nums:
            count = nums.count(i)
            corresponding.update({i:count})

    for i in corresponding:
            freq=corresponding[i]
            occurances.append(freq)

    maxFreq=max(occurances)

    keys=corresponding.keys()
    values=corresponding.values()

    index_v = values.index(maxFreq)
    global mode
    mode = keys[index_v]
    return mode

Instead of using

import os
dirname = os.path.dirname(__file__)
filename = os.path.join(dirname, 'relative/path/to/file/you/want')

as in the accepted answer, it would be more robust to use:

import inspect
import os
dirname = os.path.dirname(os.path.abspath(inspect.stack()[0][1]))
filename = os.path.join(dirname, 'relative/path/to/file/you/want')

because using __file__ will return the file from which the module was loaded, if it was loaded from a file, so if the file with the script is called from elsewhere, the directory returned will not be correct.

These answers give more detail: https://stackoverflow.com/a/31867043/5542253 and https://stackoverflow.com/a/50502/5542253

 DataSet ds = new DataSet();

 DataTable dt = new DataTable("MyTable");
 dt.Columns.Add(new DataColumn("id",typeof(int)));
 dt.Columns.Add(new DataColumn("name", typeof(string)));

 DataRow dr = dt.NewRow();
 dr["id"] = 123;
 dr["name"] = "John";
 dt.Rows.Add(dr);
 ds.Tables.Add(dt);

Taken from the javadoc spec

@see <a href="URL#value">label</a> : Adds a link as defined by URL#value. The URL#value is a relative or absolute URL. The Javadoc tool distinguishes this from other cases by looking for a less-than symbol (<) as the first character.

For example : @see <a href="http://www.google.com">Google</a>

The code finally used is the following from:

http://www.java2s.com/Code/Java/File-Input-Output/ConvertInputStreamtoString.htm

public static String convertStreamToString(InputStream is) throws Exception {
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();
    String line = null;
    while ((line = reader.readLine()) != null) {
      sb.append(line).append("\n");
    }
    reader.close();
    return sb.toString();
}

public static String getStringFromFile (String filePath) throws Exception {
    File fl = new File(filePath);
    FileInputStream fin = new FileInputStream(fl);
    String ret = convertStreamToString(fin);
    //Make sure you close all streams.
    fin.close();        
    return ret;
}

If your IEnumerable doesn't expose it's <T> and Linq fails, you can write a method using reflection:

public static T GetEnumeratedItem<T>(Object items, int index) where T : class
{
  T item = null;
  if (items != null)
  {
    System.Reflection.MethodInfo mi = items.GetType()
      .GetMethod("GetEnumerator");
    if (mi != null)
    {
      object o = mi.Invoke(items, null);
      if (o != null)
      {
        System.Reflection.MethodInfo mn = o.GetType()
          .GetMethod("MoveNext");
        if (mn != null)
        {
          object next = mn.Invoke(o, null);
          while (next != null && next.ToString() == "True")
          {
            if (index < 1)
            {
              System.Reflection.PropertyInfo pi = o
                .GetType().GetProperty("Current");
              if (pi != null) item = pi
                .GetValue(o, null) as T;
              break;
            }
            index--;
          }
        }
      }
    }
  }
  return item;
}

I experienced the same issue, and found out that the applicationdeployed was of .NET version 3.5, but the Application pool was using .NET 2.0. That caused the problem you described above. Hope it helps someone.

"Egg" is a single-file importable distribution format for Python-related projects.

"The Quick Guide to Python Eggs" notes that "Eggs are to Pythons as Jars are to Java..."

Eggs actually are richer than jars; they hold interesting metadata such as licensing details, release dependencies, etc.

Although I guess you do not need an answer any longer, I am giving the solution for those who will come to see this post.

Derived from book.cls

\def\@endpart{\vfil\newpage
              \if@twoside
                \null
                \thispagestyle{empty}%
                \newpage
              \fi
              \if@tempswa
                \twocolumn
              \fi}

It is "\newpage" at the first line of this fragment that adds a redundant blank page after the part header page. So you must redefine the command \@endpart. Add the following snippet to the beggining of your tex file.

\makeatletter
\renewcommand\@endpart{\vfil
              \if@twoside
                \null
                \thispagestyle{empty}%
                \newpage
              \fi
              \if@tempswa
                \twocolumn
              \fi}
\makeatother

To prove jkp's point that 'anything on one line will probably be helishly complex to understand', I created a one-liner. Please do not mod me down because I understand this is not a solution that you should actually use. It is just for demonstrational purposes.

The idea is to add the values in a one by one, as long as the total times you have added that value does is smaller than the total number of times this value is in a minus the number of times it is in b:

[ value for counter,value in enumerate(a) if a.count(value) >= b.count(value) + a[counter:].count(value) ]

The horror! But perhaps someone can improve on it? Is it even bug free?

Edit: Seeing Devin Jeanpierre comment about using a dictionary datastructure, I came up with this oneliner:

sum([ [value]*count for value,count in {value:a.count(value)-b.count(value) for value in set(a)}.items() ], [])

Better, but still unreadable.

As a similar approach to the accepted answer that might be considered a bit more readable, elegant, and general (YMMV), you can leverage the map method:

# OP example
df['var3'].map(lambda n: '{:,.2%}'.format(n))

# also works on a series
series_example.map(lambda n: '{:,.2%}'.format(n))

Performance-wise, this is pretty close (marginally slower) than the OP solution.

As an aside, if you do choose to go the pd.options.display.float_format route, consider using a context manager to handle state per this parallel numpy example.

As others have mentioned, perhaps the main advantage of matrix was that it provided a convenient notation for matrix multiplication.

However, in Python 3.5 there is finally a dedicated infix operator for matrix multiplication: @.

With recent NumPy versions, it can be used with ndarrays:

A = numpy.ones((1, 3))
B = numpy.ones((3, 3))
A @ B

So nowadays, even more, when in doubt, you should stick to ndarray.

If you don't want all of your SQL statements to be echoed, but you only want to see the easily identifiable results of your script, do it this way:

set echo on

REM MyFirstTable

set echo off

delete from MyFirstTable;

set echo on

REM MySecondTable

set echo off

delete from MySecondTable;

The output from the above example will look something like this:

-REM MyFirstTable

13 rows deleted.

-REM MySecondTable

27 rows deleted.

I am surprised no one mentioned hsearch/hcreate set of libraries which although is not available on windows, but is mandated by POSIX, and therefore available in Linux / GNU systems.

The link has a simple and complete basic example that very well explains its usage.

It even has thread safe variant, is easy to use and very performant.

This is a MultiThreading Issue and Using Properly Synchronized Blocks This can be prevented. Without putting extra things on UI Thread and causing loss of responsiveness of app.

I also faced the same. And as the most accepted answer suggests making change to adapter data from UI Thread can solve the issue. That will work but is a quick and easy solution but not the best one.

As you can see for a normal case. Updating data adapter from background thread and calling notifyDataSetChanged in UI thread works.

This illegalStateException arises when a ui thread is updating the view and another background thread changes the data again. That moment causes this issue.

So if you will synchronize all the code which is changing the adapter data and making notifydatasetchange call. This issue should be gone. As gone for me and i am still updating the data from background thread.

Here is my case specific code for others to refer.

My loader on the main screen loads the phone book contacts into my data sources in the background.

    @Override
    public Void loadInBackground() {
        Log.v(TAG, "Init loadings contacts");
        synchronized (SingleTonProvider.getInstance()) {
            PhoneBookManager.preparePhoneBookContacts(getContext());
        }
    }

This PhoneBookManager.getPhoneBookContacts reads contact from phonebook and fills them in the hashmaps. Which is directly usable for List Adapters to draw list.

There is a button on my screen. That opens a activity where these phone numbers are listed. If i directly setAdapter over the list before the previous thread finishes its work which is fast naviagtion case happens less often. It pops up the exception .Which is title of this SO question. So i have to do something like this in the second activity.

My loader in the second activity waits for first thread to complete. Till it shows a progress bar. Check the loadInBackground of both the loaders.

Then it creates the adapter and deliver it to the activity where on ui thread i call setAdapter.

That solved my issue.

This code is a snippet only. You need to change it to compile well for you.

@Override
public Loader<PhoneBookContactAdapter> onCreateLoader(int arg0, Bundle arg1) {
    return new PhoneBookContactLoader(this);
}

@Override
public void onLoadFinished(Loader<PhoneBookContactAdapter> arg0, PhoneBookContactAdapter arg1) {
    contactList.setAdapter(adapter = arg1);
}

/*
 * AsyncLoader to load phonebook and notify the list once done.
 */
private static class PhoneBookContactLoader extends AsyncTaskLoader<PhoneBookContactAdapter> {

    private PhoneBookContactAdapter adapter;

    public PhoneBookContactLoader(Context context) {
        super(context);
    }

    @Override
    public PhoneBookContactAdapter loadInBackground() {
        synchronized (SingleTonProvider.getInstance()) {
            return adapter = new PhoneBookContactAdapter(getContext());    
        }
    }

}

Hope this helps

PostgreSQL DLL to add an FK column:

ALTER TABLE one
ADD two_id INTEGER REFERENCES two;

You might also consider adding ".

For example for %i in (*.wav) do opusenc "%~ni.wav" "%~ni.opus" is very good idea.

1) You can download and upload below files on your site

<link href="/Style%20Library/css/smoothness/jquery.alerts.css" type="text/css" rel="stylesheet"/> 

2) after that you can directly use below code

$.alerts.okButton = "yes"; $.alerts.cancelButton = "no";

in document.ready function.

Please try it will work.

Thanks

I've given up trying to align my text on buttons! Now, if I need it, I'm using <a> tags, like so:

<a href="javascript:void();" style="display:block;font-size:1em;padding:5px;cursor:default;" onclick="document.getElementById('form').submit();">Submit</a>

So, if the document's font size is 12px, my "button" will have 22px height. And the text will be vertically align. That in theory, because, in some casses, an unequal padding of "6px 5px 4px 5px" will do the job done.

Although, is a hack, this technique is pretty good for solving compatibility issues in older browsers too, like IE6!

You can consider using numpy.putmask:

np.putmask(arr, arr>=T, 255.0)

Here is a performance comparison with the Numpy's builtin indexing:

In [1]: import numpy as np
In [2]: A = np.random.rand(500, 500)

In [3]: timeit np.putmask(A, A>0.5, 5)
1000 loops, best of 3: 1.34 ms per loop

In [4]: timeit A[A > 0.5] = 5
1000 loops, best of 3: 1.82 ms per loop

Here's a way to do it:

console.log("%o", obj);

The idea is to extract the keys of your map into an array. Sort this array. Then iterate over this sorted array, get its value pair from the unsorted map and put them into a new map. The new map will be in sorted order. The code below is it's implementation:

var unsortedMap = new Map();
unsortedMap.set('2-1', 'foo');
unsortedMap.set('0-1', 'bar');

// Initialize your keys array
var keys = [];
// Initialize your sorted maps object
var sortedMap = new Map();

// Put keys in Array
unsortedMap.forEach(function callback(value, key, map) {
    keys.push(key);
});

// Sort keys array and go through them to put in and put them in sorted map
keys.sort().map(function(key) {
    sortedMap.set(key, unsortedMap.get(key));
});

// View your sorted map
console.log(sortedMap);

It is because there is a DLL that your program is missing or can't find.

In your case I believe you are missing the openCV dlls. You can find these under the "build" directory that comes with open CV. If you are using VS2010 and building to an x86 program you can locate your dlls here under "opencv\build\x86\vc10\bin". Simply copy all these files to your Debug and Release folders and it should resolve your issues.

Generally you can resolve this issue using the following procedure:

1. Download Dependency Walker from here: http://www.dependencywalker.com/
2. Load your .exe file into Dependency Walker (under your projects Debug or Release folder), in your case this would be DisplayImage.exe
3. Look for any DLL's that are missing, or are corrupt, or are for the wrong architecture (i.e. x64 instead of x86) these will be highlighted in red.
4. For each DLL that you are missing either copy to your Debug or Release folders with your .exe, or install the required software, or add the path to the DLLs to your environment variables (Win+Pause -> Advanced System Settings -> Environment Variables)

Remember that you will need to have these DLLs in the same directory as your .exe. If you copy the .exe from the Release folder to somewhere else then you will need those DLLs copied with the .exe as well. For portability I tend to try and have a test Virtual Machine with a clean install of Windows (no updates or programs installed), and I walk through the Dependencies using the Dependency Walker one by one until the program is running happily.

This is a common problem. Also see these questions:

Here it is my solution to get back normal preferences. Write in Key Bindings - User :

{ "keys": ["ctrl+:"], "command": "toggle_comment", "args": { "block": false } }, { "keys": ["ctrl+shift+:"], "command": "toggle_comment", "args": { "block": true } }

your first try is using declarative pipelines, and the second working one is using scripted pipelines. you need to enclose steps in a steps declaration, and you can't use if as a top-level step in declarative, so you need to wrap it in a script step. here's a working declarative version:

pipeline {
    agent any

    stages {
        stage('test') {
            steps {
                sh 'echo hello'
            }
        }
        stage('test1') {
            steps {
                sh 'echo $TEST'
            }
        }
        stage('test3') {
            steps {
                script {
                    if (env.BRANCH_NAME == 'master') {
                        echo 'I only execute on the master branch'
                    } else {
                        echo 'I execute elsewhere'
                    }
                }
            }
        }
    }
}

you can simplify this and potentially avoid the if statement (as long as you don't need the else) by using "when". See "when directive" at https://jenkins.io/doc/book/pipeline/syntax/. you can also validate jenkinsfiles using the jenkins rest api. it's super sweet. have fun with declarative pipelines in jenkins!

This works for me when disabling finish Activity animation.

@Override
protected void onPause() {
    super.onPause();
    overridePendingTransition(0, 0);
}
