As mklement0 points out, a feature for listing all Makefile targets is missing from GNU-make, and his answer and others provides ways to do this.

However, the original post also mentions rake, whose tasks switch does something slightly different than just listing all tasks in the rakefile. Rake will only give you a list of tasks that have associated descriptions. Tasks without descriptions will not be listed. This gives the author the ability to both provide customized help descriptions and also omit help for certain targets.

If you want to emulate rake's behavior, where you provide descriptions for each target, there is a simple technique for doing this: embed descriptions in comments for each target you want listed.

You can either put the description next to the target or, as I often do, next to a PHONY specification above the target, like this:

.PHONY: target1 # Target 1 help text
target1: deps
    [... target 1 build commands]

.PHONY: target2 # Target 2 help text
target2:
    [... target 2 build commands]

...                                                                                                         

.PHONY: help # Generate list of targets with descriptions                                                                
help:                                                                                                                    
    @grep '^.PHONY: .* #' Makefile | sed 's/\.PHONY: \(.*\) # \(.*\)/\1 \2/' | expand -t20

Which will yield

$ make help
target1             Target 1 help text
target2             Target 2 help text

...
help                Generate list of targets with descriptions

You can also find a short code example in this gist and here too.

Again, this does not solve the problem of listing all the targets in a Makefile. For example, if you have a big Makefile that was maybe generated or that someone else wrote, and you want a quick way to list its targets without digging through it, this won't help.

However, if you are writing a Makefile, and you want a way to generate help text in a consistent, self-documenting way, this technique may be useful.

It seems the new version of msbuild does not ship with Microsoft.WebApplication.targets. To fix you need to update your csproj file as so:

1) Edit the web app csproj (right click). Find the section in the csproj towards the bottom concerning build tools. It should look like so.

<PropertyGroup>  
  <VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''">10.0</VisualStudioVersion>
</PropertyGroup>  
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />  
<Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != ''" />  
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" Condition="false" />  

2) You need to add one VSToolsPath line below the VisualStudioVersion tag so it looks like so

<PropertyGroup>  
  <VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''">10.0</VisualStudioVersion>
  <!--Add the below line to fix the project loading in VS 2017 -->
  <VSToolsPath Condition="'$(VSToolsPath)' == ''">$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)</VSToolsPath>
  <!--End -->
</PropertyGroup>  
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />  
<Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != ''" />  
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" Condition="false" />

I think your code should work just remove one thing from here but it'll do redirection from current page within existing window

<asp:Button ID="btn" runat="Server" Text="SUBMIT" 

 OnClick="btnNewEntry_Click"/>    



protected void btnNewEntry_Click(object sender, EventArgs e)
 {
    Response.Redirect("CMS_1.aspx");
 }

And if u wanna do the this via client side scripting Use this way

<asp:Button ID="BTN" runat="server" Text="Submit" OnClientClick="window.open('Default2.aspx')" />

According to me you should prefer the Client Side Scripting because just to open a new window server side will take a post back and that will be useless..

My shortened version in Python3

print(open('file.txt').read())

I found that pathlib module also supports this.

from pathlib import Path
>>> Path.home()
WindowsPath('C:/Users/XXX')

adb shell ip addr > ippdetails.txt This will get all list of ip's assigned to devices.

import pyclbr
print(pyclbr.readmodule(__name__).keys())

Note that the stdlib's Python class browser module uses static source analysis, so it only works for modules that are backed by a real .py file.

imshow() only works with waitKey():

import cv2
img = cv2.imread('C:/Python27/03323_HD.jpg')
cv2.imshow('ImageWindow', img)
cv2.waitKey()

(The whole message-loop necessary for updating the window is hidden in there.)

This being a very old question but worth adding that I have just had a similar issue where a background colour on a footer element in my case didn't show. I added a position: relative which worked.

In my case was webpack having the UglifyPlugin running with drop_console: true set

The short answer: there is no difference.

The long answer: CHARACTER VARYING is the official type name from the ANSI SQL standard, which all compliant databases are required to support. VARCHAR is a shorter alias which all modern databases also support. I prefer VARCHAR because it's shorter and because the longer name feels pedantic. However, postgres tools like pg_dump and \d will output character varying.

From the AWS documentation:

Amazon SNS allows applications to send time-critical messages to multiple subscribers through a “push” mechanism, eliminating the need to periodically check or “poll” for updates.

Amazon SQS is a message queue service used by distributed applications to exchange messages through a polling model, and can be used to decouple sending and receiving components—without requiring each component to be concurrently available.

Fanout to Amazon SQS queues

Figure sizes are specified in inches and can be included as a global option of the document output format. For example:

---
title: "My Document"
output:
  html_document:
    fig_width: 6
    fig_height: 4
---

And the plot's size in the graphic device can be increased at the chunk level:

```{r, fig.width=14, fig.height=12}          #Expand the plot width to 14 inches

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

You can also use the out.width and out.height arguments to directly define the size of the plot in the output file:

```{r, out.width="200px", out.height="200px"} #Expand the plot width to 200 pixels

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

SOLVED

1. Just run CMD as an administrator.
2. Make sure your using the correct truststore password

$data = User::toSql();
echo $data; //this will retrun select * from users. //here User is model

Use the 'merge' step of merge sort, it runs in O(n) time.

From wikipedia (pseudo-code):

function merge(left,right)
    var list result
    while length(left) > 0 and length(right) > 0
        if first(left) = first(right)
            append first(left) to result
            left = rest(left)
        else
            append first(right) to result
            right = rest(right)
    end while
    while length(left) > 0 
        append left to result
    while length(right) > 0 
        append right to result
    return result

Based on the git documentation the best way is:

1. be sure the actual origin path:

git remote -v

3. Then make the change with:

git remote set-url origin

where url-repository is the same URL that we get from the clone option.

If you think about the performace ,may be you can use "PERFORM" in a function just like this:

 PERFORM 1 FROM skytf.test_2 WHERE id=i LIMIT 1;
  IF FOUND THEN
      RAISE NOTICE ' found record id=%', i;  
  ELSE
      RAISE NOTICE ' not found record id=%', i;  
 END IF;

b = a[a>threshold] this should do

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

$ python test.py
0:00:00.028000
0:00:02.461000

That's strange, it definitely works for me:

from matplotlib import pyplot as plt

plt.figure(figsize = (20,2))
plt.imshow(random.rand(8, 90), interpolation='nearest')

I am using the "MacOSX" backend, btw.

It was talked about it a lot already, u can find even on Wiki the reasons...

• C/C++ for the game engine and all intensive stuff.
• Lua or Python for scripting in the game.
• Java - very-very bad performance, big memory usage + it's not available on Game Consoles(It is used for some very simple games(Yes, Runescape counts in here, it's not Battlefield or Crysis or what else is there) just because there are a lot of programmers that know this programming language).
• C# - big memory usage(It is used for some very simple games just because there are pretty much programmers that know this programming language).

And I hear more and more Java programmers that try to convince people that Java is not slow, it is not slow for drawing a widget on the screen and drawing some ASCII characters on the widget, to receive and send data through network(And it is recommended to use it in this cases(network data manipulation) instead of C/C++)... But it is damn slow when it comes to serious stuff like math calculations, memory allocation/manipulation and a lot of this good stuff.

I remember an article on MIT site where they show what C/C++ can do if u use the language and compiler features: A matrix multiplier(2 matrices), 1 implementation in Java and 1 implementation in C/C++, with C/C++ features and appropriate compiler optimisations activated, the C/C++ implementation was ~296 260 times faster than the Java implementation.

I hope you understand now why people use C/C++ instead of Java in games, imagine Crysis in Java, there would not be any computer in this world which could handle that... + Garbage collection works ok for Widgets which just destroyed an image but it's still cached in there and needs to be cleaned but not for games, for sure, u will have even more lags on every garbage collection activation.

Edit: Because somebody asked for the article, here, I searched in the web archive to get that, I hope you are satisfied...MIT Case Study

And to add, no, Java for gaming is still an awful idea. Just a few days ago a big company that I will not name started rewriting their game client from Java to C++ because a very simple game(In terms of Graphics) was lagging and heating i7 Laptops with powerful nVidia GT 5xx and 6xx generation video cards(not only nVidia, the point here is that this powerful cards that can handle on Max settings most of the new games and can't handle this game) and the memory consumption was ~2.5 - 2.6 GB Ram. For such simple graphics it needs a beast of a machine.

Looks file you use the .mkdirs() method on a File object: http://www.roseindia.net/java/beginners/java-create-directory.shtml

// Create a directory; all non-existent ancestor directories are
// automatically created
success = (new File("../potentially/long/pathname/without/all/dirs")).mkdirs();
if (!success) {
    // Directory creation failed
}

I use the InvokeOnClick() method. It takes two arguments: Control and EventArgs. If you need the EventArgs, then create an instance of it and pass it in, else use InvokeOnClick(controlToClick, null);. You can use a variety of Mouse event related arguments that derive from EventArgs such as MouseEventArgs.

I found one answer on the net and it worked for me, thus here it is:

When you get the gradle project sync failed error, with error details:

Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.

Then, on Windows, please go to:

Control Panel > System > Advanced(tab) > Environment Variables > System Variables > New:

Variable name _JAVA_OPTIONS and Variable value -Xmx512M

Save it, restart AS. It might work this time, as it did for me.

My solution was to use excel (2010).

In a new worksheet, select a cell, then:

Data -> From Other Sources -> From SQL Server 

put in the server name, select table, etc,

When you get to the "Import Data" dialog,
click on Properties in the "Connection Properties" dialog,
select the "Definition" tab.

And there Excel nicely displays the Connection String for copying
(or even Export Connection File...)

While most of the above answers provide a way to do this, there is already a built-in way to accomplish this and it's 1 line of code (ThumbnailUtils.extractThumbnail())

int dimension = getSquareCropDimensionForBitmap(bitmap);
bitmap = ThumbnailUtils.extractThumbnail(bitmap, dimension, dimension);

...

//I added this method because people keep asking how 
//to calculate the dimensions of the bitmap...see comments below
public int getSquareCropDimensionForBitmap(Bitmap bitmap)
{
    //use the smallest dimension of the image to crop to
    return Math.min(bitmap.getWidth(), bitmap.getHeight());
}

If you want the bitmap object to be recycled, you can pass options that make it so:

bitmap = ThumbnailUtils.extractThumbnail(bitmap, dimension, dimension, ThumbnailUtils.OPTIONS_RECYCLE_INPUT);

From: ThumbnailUtils Documentation

public static Bitmap extractThumbnail (Bitmap source, int width, int height)

Added in API level 8 Creates a centered bitmap of the desired size.

Parameters source original bitmap source width targeted width height targeted height

I was getting out of memory errors sometimes when using the accepted answer, and using ThumbnailUtils resolved those issues for me. Plus, this is much cleaner and more reusable.

Yes. The inheritance is public by default.

Syntax (example):

struct A { };
struct B : A { };
struct C : B { };

Based on the original HTML posted by Paolo I came up with the following.

$("#list").change(function() {
    alert($(this).find("option:selected").text()+' clicked!');
});

It has been tested to work on Internet Explorer and Firefox.

To print a specific row we have couple of pandas method

1. loc - It only get label i.e column name or Features
2. iloc - Here i stands for integer, actually row number
3. ix - It is a mix of label as well as integer

How to use for specific row

1. loc

df.loc[row,column]

For first row and all column

df.loc[0,:]

For first row and some specific column

df.loc[0,'column_name']

2. iloc

For first row and all column

df.iloc[0,:]

For first row and some specific column i.e first three cols

df.iloc[0,0:3]

Normally I would recommend floating but from your 3 requirements I would suggest this:

position: absolute;
right: 10px;
top: 5px;

Don't forget position: relative; on the parent div

DEMO

Here is from pandas docs on advanced indexing:

The section will explain exactly what you need! Turns out df.loc (as .ix has been deprecated -- as many have pointed out below) can be used for cool slicing/dicing of a dataframe. And. It can also be used to set things.

df.loc[selection criteria, columns I want] = value

So Bren's answer is saying 'find me all the places where df.A == 0, select column B and set it to np.nan'

This one uses a git plumbing command read-tree, but makes for a shorter overall workflow.

git checkout <base-branch>

git merge --no-commit -s ours <their-branch>
git read-tree -u --reset <their-branch>
git commit

# Check your work!
git diff <their-branch>

Try either multi-table update syntax

UPDATE config t1 JOIN config t2
    ON t1.config_name = 'name1' AND t2.config_name = 'name2'
   SET t1.config_value = 'value',
       t2.config_value = 'value2';

Here is SQLFiddle demo

or conditional update

UPDATE config
   SET config_value = CASE config_name 
                      WHEN 'name1' THEN 'value' 
                      WHEN 'name2' THEN 'value2' 
                      ELSE config_value
                      END
 WHERE config_name IN('name1', 'name2');

Here is SQLFiddle demo

The pull command is:

adb pull source dest

When you write:

adb pull /data/data/path.to.package/databases/data /sdcard/test

It means that you'll pull from /data/data/path.to.package/databases/data and you'll copy it to /sdcard/test, but the destination MUST be a local directory. You may write C:\Users\YourName\temp instead.

For example:

adb pull /data/data/path.to.package/databases/data c:\Users\YourName\temp

This is the easiest way I found:

        BtnUpload.Style.Add("display", "none");
        FileUploader.Style.Add("display", "none");
        BtnAccept.Style.Add("display", "inherit");
        BtnClear.Style.Add("display", "inherit");

I have the opposite in the Else, so it handles displaying them as well. This can go in the Page's Load or in a method to refresh the controls on the page.

I had this problem because i was adding bundle and certificate in wrong order so maybe this could help someone else.

Before (which is wrong) :

cat ca_bundle.crt certificate.crt > bundle_chained.crt

After (which is right)

cat certificate.crt ca_bundle.crt > bundle_chained.crt

And Please don't forget to update the appropriate conf (ssl_certificate must now point to the chained crt) as

server {
    listen              443 ssl;
    server_name         www.example.com;
    ssl_certificate     bundle_chained.crt;
    ssl_certificate_key www.example.com.key;
    ...
}

From the nginx manpage:

If the server certificate and the bundle have been concatenated in the wrong order, nginx will fail to start and will display the error message:

SSL_CTX_use_PrivateKey_file(" ... /www.example.com.key") failed
   (SSL: error:0B080074:x509 certificate routines:
    X509_check_private_key:key values mismatch)

function user() { 

       parent::Model(); 

} 

=> class name is User, construct name is User.

function User() { 

       parent::Model(); 

} 

If you're using Eclipse Collections, you can use the makeString() method.

ArrayList<String> list = new ArrayList<String>();
list.add("one");
list.add("two");
list.add("three");

Assert.assertEquals(
    "one\ttwo\tthree",
    ArrayListAdapter.adapt(list).makeString("\t"));

If you can convert your ArrayList to a FastList, you can get rid of the adapter.

Assert.assertEquals(
    "one\ttwo\tthree",
    FastList.newListWith("one", "two", "three").makeString("\t"));

Note: I am a committer for Eclipse Collections.

I had the same problem and found two different solutions (see this thread for more details). Both reduced the size of my uncompressed PDF dramatically.

• Pixelated (lossy):

  convert input.pdf -compress Zip output.pdf
  

• Unpixelated (lossless, but may display slightly differently):

  gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dBATCH  -dQUIET -sOutputFile=output.pdf input.pdf
  

Edit: I just discovered another option (for lossless compression), which avoids the nasty gs command. qpdf is a neat tool that converts PDFs (compression/decompression, encryption/decryption), and is much faster than the gs command:

qpdf --linearize input.pdf output.pdf

I have a helper method for this in my System.Web.UI.Page class

protected T FindControlFromMaster<T>(string name) where T : Control
{
     MasterPage master = this.Master;
     while (master != null)
     {
         T control = master.FindControl(name) as T;
         if (control != null)
             return control;

         master = master.Master;
     }
     return null;
}

then you can access using below code.

Label lblStatus = FindControlFromMaster<Label>("lblStatus");
if(lblStatus!=null) 
    lblStatus.Text = "something";

If you are looking for a solution to your particular case, it would be:

Date date = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'").parse("2012-05-20T09:00:00.000Z");
String formattedDate = new SimpleDateFormat("dd/MM/yyyy, Ka").format(date);

While the question has been answered, I'd like to add some useful tips when using matplotlib.pyplot.savefig. The file format can be specified by the extension:

from matplotlib import pyplot as plt

plt.savefig('foo.png')
plt.savefig('foo.pdf')

Will give a rasterized or vectorized output respectively, both which could be useful. In addition, you'll find that pylab leaves a generous, often undesirable, whitespace around the image. You can remove the whitespace using:

plt.savefig('foo.png', bbox_inches='tight')

Single line result:

base64 -w 0 DSC_0251.JPG

For HTML:

echo "data:image/jpeg;base64,$(base64 -w 0 DSC_0251.JPG)"

As file:

base64 -w 0 DSC_0251.JPG > DSC_0251.JPG.base64

In variable:

IMAGE_BASE64="$(base64 -w 0 DSC_0251.JPG)"

In variable for HTML:

IMAGE_BASE64="data:image/jpeg;base64,$(base64 -w 0 DSC_0251.JPG)"

Get you readable data back:

base64 -d DSC_0251.base64 > DSC_0251.JPG 

See: http://www.greywyvern.com/code/php/binary2base64

The Natural Language Toolkit (nltk.org) has what you need. This group posting indicates this does it:

import nltk.data

tokenizer = nltk.data.load('tokenizers/punkt/english.pickle')
fp = open("test.txt")
data = fp.read()
print '\n-----\n'.join(tokenizer.tokenize(data))

(I haven't tried it!)

you can also use

.detail_container h1:nth-of-type(1)

By changing the number 1 by any other number you can select any other h1 item.

If you want input comma separated string as input & apply in in query in that then you can make Function like:

create FUNCTION [dbo].[Split](@String varchar(MAX), @Delimiter char(1))       
    returns @temptable TABLE (items varchar(MAX))       
    as       
    begin      
        declare @idx int       
        declare @slice varchar(8000)       

        select @idx = 1       
            if len(@String)<1 or @String is null  return       

        while @idx!= 0       
        begin       
            set @idx = charindex(@Delimiter,@String)       
            if @idx!=0       
                set @slice = left(@String,@idx - 1)       
            else       
                set @slice = @String       

            if(len(@slice)>0)  
                insert into @temptable(Items) values(@slice)       

            set @String = right(@String,len(@String) - @idx)       
            if len(@String) = 0 break       
        end   
    return 
    end;

You can use it like :

Declare @Values VARCHAR(MAX);

set @Values ='1,2,5,7,10';
Select * from DBTable
    Where id  in (select items from [dbo].[Split] (@Values, ',') )

Alternatively if you don't have comma-separated string as input, You can try Table variable OR TableType Or Temp table like: INSERT using LIST into Stored Procedure

You can do this with map()

var arrOfObj = [{_x000D_
  name: 'eve'_x000D_
}, {_x000D_
  name: 'john'_x000D_
}, {_x000D_
  name: 'jane'_x000D_
}];_x000D_
_x000D_
var result = arrOfObj.map(function(o) {_x000D_
  o.isActive = true;_x000D_
  return o;_x000D_
})_x000D_
_x000D_
console.log(result)

If you want to keep original array you can clone objects with Object.assign()

var arrOfObj = [{_x000D_
  name: 'eve'_x000D_
}, {_x000D_
  name: 'john'_x000D_
}, {_x000D_
  name: 'jane'_x000D_
}];_x000D_
_x000D_
var result = arrOfObj.map(function(el) {_x000D_
  var o = Object.assign({}, el);_x000D_
  o.isActive = true;_x000D_
  return o;_x000D_
})_x000D_
_x000D_
console.log(arrOfObj);_x000D_
console.log(result);

mysqli_error()

As in:

$sql = "Your SQL statement here";
$result = mysqli_query($conn, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($conn), E_USER_ERROR);

Trigger error is better than die because you can use it for development AND production, it's the permanent solution.

You can not use strtotime as your time format is not within the supported date and time formats of PHP.

Therefor, you have to create a valid date format first making use of createFromFormat function.

//creating a valid date format
$newDate = DateTime::createFromFormat('YmdHi', $longdate);

//formating the date as we want
$finalDate = $newDate->format('D'); 

Your date time string doesn't contains any seconds. You need to reflect that in your format (remove the :ss).
Also, you need to specify H instead of h if you are using 24 hour times:

DateTime.ParseExact("04/30/2013 23:00", "MM/dd/yyyy HH:mm", CultureInfo.InvariantCulture)

See here for more information:

Custom Date and Time Format Strings

try this

 private void Form1_Load(object sender, EventArgs e)
    {
        notifyIcon1.BalloonTipText = "Application Minimized.";
        notifyIcon1.BalloonTipTitle = "test";
    }

    private void Form1_Resize(object sender, EventArgs e)
    {
        if (WindowState == FormWindowState.Minimized)
        {
            ShowInTaskbar = false;
            notifyIcon1.Visible = true;
            notifyIcon1.ShowBalloonTip(1000);
        }
    }

    private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        ShowInTaskbar = true;
        notifyIcon1.Visible = false;
        WindowState = FormWindowState.Normal;
    }

This is my answer which solved the same problem. Fragment2.java is the fragment class which holds the layout of fragment2.xml.

public void onClick(View v) {
                    Fragment  fragment2 = new Fragement2();
                    FragmentManager fragmentManager = getFragmentManager();
                    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                    fragmentTransaction.replace(R.id.frame_container, fragment2);
                    fragmentTransaction.addToBackStack(null);
                    fragmentTransaction.commit();   
                }

The soapAction must passed as a http-header parameter - when used, it's not part of the http-body/payload.

Look here for an example with apache httpclient: http://svn.apache.org/repos/asf/httpcomponents/oac.hc3x/trunk/src/examples/PostSOAP.java

I did it this way.

Create the directive

function finRepeat() {
    return function(scope, element, attrs) {
        if (scope.$last){
            // Here is where already executes the jquery
            $(document).ready(function(){
                $('.materialboxed').materialbox();
                $('.tooltipped').tooltip({delay: 50});
            });
        }
    }
}

angular
    .module("app")
    .directive("finRepeat", finRepeat);

After you add it on the label where this ng-repeat

<ul>
    <li ng-repeat="(key, value) in data" fin-repeat> {{ value }} </li>
</ul>

And ready with that will be run at the end of the ng-repeat.

Use the load event:

img = new Image();

img.onload = function(){
  // image  has been loaded
};

img.src = image_url;

Also have a look at:

• Preloading and the JavaScript Image() object

Unfortunately, for some reasons probably linked with HTTPS and certificates, the native .NET HttpListener requires admin privileges, and even for HTTP only protocol...

The good point

It is interesting to note that HTTP protocol is on top of TCP protocol, but launching a C# TCP listener doesn't require any admin privileges to run. In other words, it is conceptually possible to implement an HTTP server which do not requires admin privileges.

Alternative

Below, an example of project which doesn't require admin privileges: https://github.com/EmilianoElMariachi/ElMariachi.Http.Server

Even more simple if you accept using pandas :

import pandas
result = {0: 1.1181753789488595, 1: 0.5566080288678394, 2: 0.4718269778030734, 3: 0.48716683119447185, 4: 1.0, 5: 0.1395076201641266, 6: 0.20941558441558442}
df = pandas.DataFrame(result, index=[0])
print df

gives :

          0         1         2         3  4         5         6
0  1.118175  0.556608  0.471827  0.487167  1  0.139508  0.209416

This is fairly easy, using marshalling.

Top of file

using System.Runtime.InteropServices

Function

byte[] getBytes(CIFSPacket str) {
    int size = Marshal.SizeOf(str);
    byte[] arr = new byte[size];

    IntPtr ptr = Marshal.AllocHGlobal(size);
    Marshal.StructureToPtr(str, ptr, true);
    Marshal.Copy(ptr, arr, 0, size);
    Marshal.FreeHGlobal(ptr);
    return arr;
}

And to convert it back:

CIFSPacket fromBytes(byte[] arr) {
    CIFSPacket str = new CIFSPacket();

    int size = Marshal.SizeOf(str);
    IntPtr ptr = Marshal.AllocHGlobal(size);

    Marshal.Copy(arr, 0, ptr, size);

    str = (CIFSPacket)Marshal.PtrToStructure(ptr, str.GetType());
    Marshal.FreeHGlobal(ptr);

    return str;
}

In your structure, you will need to put this before a string

[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 100)]
public string Buffer;

And make sure SizeConst is as big as your biggest possible string.

And you should probably read this: http://msdn.microsoft.com/en-us/library/4ca6d5z7.aspx

Actually, it will takes 101 bytes.

MySQL Reference

As mentioned in this tutorial, it's as simple as:

To install

brew install gradle

To upgrade

brew upgrade gradle

(using Homebrew of course)

Also see (finally) updated docs.

Cheers :)!

If some one is still finding difficulties, i have made a video on this

https://www.youtube.com/watch?v=tbLAHKhjjI4

Because the new version of Apple does not support bash shell so i have explained in details how do we set variables in 2020.

You can also try to get the column names from panda data frame that returns columnn name as well dtype. here i'll read csv file from https://mlearn.ics.uci.edu/databases/autos/imports-85.data but you have define header that contain columns names.

import pandas as pd

url="https://mlearn.ics.uci.edu/databases/autos/imports-85.data"

df=pd.read_csv(url,header = None)

headers=["symboling","normalized-losses","make","fuel-type","aspiration","num-of-doors","body-style",
         "drive-wheels","engine-location","wheel-base","length","width","height","curb-weight","engine-type",
         "num-of-cylinders","engine-size","fuel-system","bore","stroke","compression-ratio","horsepower","peak-rpm"
         ,"city-mpg","highway-mpg","price"]

df.columns=headers

print df.columns

I know, it is long ago, but since the easiest answer was not yet posted I will do so for other user that might step by.

Just move the var inside the "name" block:

- name: Download apache
  vars:
    url: czxcxz
  shell: wget {{url}} 

1. use single quotes for strings
2. do NOT put single quotes around table names(use ` instead)
3. do NOT put single quotes around numbers (you can, but it's harder to read)
4. do NOT put AND between ORDER BY and LIMIT
5. do NOT put = between ORDER BY, LIMIT keywords and condition

So you query will look like:

SELECT post_datetime 
FROM post 
WHERE type = 'published' 
ORDER BY post_datetime DESC 
LIMIT 3

After formatting the previous answer to my own code, I have found an efficient way to copy all necessary data if you are attempting to paste the values returned via AutoFilter to a separate sheet.

With .Range("A1:A" & LastRow)
    .Autofilter Field:=1, Criteria1:="=*" & strSearch & "*"
    .Offset(1,0).SpecialCells(xlCellTypeVisible).Cells.Copy
    Sheets("Sheet2").activate
    DestinationRange.PasteSpecial
End With

In this block, the AutoFilter finds all of the rows that contain the value of strSearch and filters out all of the other values. It then copies the cells (using offset in case there is a header), opens the destination sheet and pastes the values to the specified range on the destination sheet.

Just define a getter.

class MyClass
{
  get MY_CONST () { return 'string'; }

  constructor ()
  {
    console.log ("MyClass MY_CONST:", this.MY_CONST);
  }
}

var obj = new MyClass();

you could use setAttribute.

Example: For adding one class:

 document.getElementById('main').setAttribute("class","classOne"); 

For multiple classes:

 document.getElementById('main').setAttribute("class", "classOne classTwo"); 

If bringing existing Visual Studio 2015 solution into Visual Studio 2017 and you want to build it with c++17 native compiler, you should first Retarget the solution/projects to v141 , THEN the dropdown will appear as described above ( Configuration Properties -> C/C++ -> Language -> Language Standard)

@jstn's answer is good, but a bit verbose. Swift is known as a protocol-oriented language, so we can achieve the same result without having to implement boilerplate code for every class in the integer family, by adding a default implementation for the protocol extension.

public extension ExpressibleByIntegerLiteral {
    public static func arc4random() -> Self {
        var r: Self = 0
        arc4random_buf(&r, MemoryLayout<Self>.size)
        return r
    }
}

Now we can do:

let i = Int.arc4random()
let j = UInt32.arc4random()

and all other integer classes are ok.

1. Change your controller name first letter to uppercase.
2. Change your url same as your controller name.

e.g:

Your controller name is YourController

Your url must be:

http://example.com/index.php/YourController/method

Not be:

http://example.com/index.php/yourcontroller/method

Check that your labels aren't set to automatically resize. In IB, it's called "Autoshrink" and is right beside the font setting. Programmatically, it's called adjustsFontSizeToFitWidth.

2^8 = 256 Characters. A character in binary is a series of 8 ( 0 or 1).

npm pack + package.json

This is what worked for me:

STEP 1: In module project, execute npm pack:

This will build a <package-name>-<version>.tar.gz file.

STEP 2: Move the file to the consumer project

Ideally you can put all such files in a tmp folder in your consumer-project root:

STEP 3: Refer it in your package.json:

"dependencies": {
  "my-package": "file:/./tmp/my-package-1.3.3.tar.gz"
}

STEP 4: Install the packages:

npm install or npm i or yarn

Now, your package would be available in your consumer-project's node_modules folder.

Good Luck...

Last column in your input file must have some data in it (be it space or char, but not null). I guess, 1st record contains null after last ',' which sqlldr won't recognize unless specifically asked to recognize nulls using TRAILING NULLCOLS option. Alternatively, if you don't want to use TRAILING NULLCOLS, you will have to take care of those NULLs before you pass the file to sqlldr. Hope this helps

"most convenient block of data" probably refers to the width (in bits) of the WORD, in correspondance to the system bus width, or whatever underlying "bandwidth" is available. On a 16 bit system, with WORD being defined as 16 bits wide, moving data around in chunks the size of a WORD will be the most efficient way. (On hardware or "system" level.)

With Java being more or less platform independant, it just defines a "WORD" as the next size from a "BYTE", meaning "full bandwidth". I guess any platform that's able to run Java will use 32 bits for a WORD.

If you you want to copy a sub-set of the source table you can do:

INSERT INTO def (field_1, field_2, field3)

SELECT other_field_1, other_field_2, other_field_3 from `abc`

or to copy ALL fields from the source table to destination table you can do more simply:

INSERT INTO def 
SELECT * from `abc`

In Perl prior to 5.10, you can say

#!/usr/bin/perl

use strict;
use warnings;

my @a = qw/a b c d e/;

my $index;
for my $elem (@a) {
    print "At index ", $index++, ", I saw $elem\n";
}

#or

for my $index (0 .. $#a) {
    print "At index $index I saw $a[$elem]\n";
}

In Perl 5.10, you use state to declare a variable that never gets reinitialized (unlike ones created with my). This lets you keep the $index variable in a smaller scope, but it can lead to bugs (if you enter the loop a second time it will still have the last value):

#!/usr/bin/perl

use 5.010;
use strict;
use warnings;

my @a = qw/a b c d e/;

for my $elem (@a) {
    state $index;
    say "At index ", $index++, ", I saw $elem";
}

In Perl 5.12 you can say

#!/usr/bin/perl

use 5.012; # This enables strict
use warnings;

my @a = qw/a b c d e/;

while (my ($index, $elem) = each @a) {
    say "At index $index I saw $elem";
}

But be warned: you there are restrictions to what you are allowed to do with @a while iterating over it with each.

It won't help you now, but in Perl 6 you will be able to say

#!/usr/bin/perl6

my @a = <a b c d e>;
for @a Z 0 .. Inf -> $elem, $index {
    say "at index $index, I saw $elem"
}

The Z operator zips the two lists together (i.e. it takes one element from the first list, then one element from the second, then one element from the first, and so on). The second list is a lazy list that contains every integer from 0 to infinity (at least theoretically). The -> $elem, $index says that we are taking two values at a time from the result of the zip. The rest should look normal to you (unless you are not familiar with the say function from 5.10 yet).

__stdcall is used to put the function arguments in the stack. After the completion of the function it automatically deallocates the memory. This is used for fixed arguments.

void __stdcall fnname ( int, int* )
{
    ...
}

int main()
{
    CreateThread ( NULL, 0, fnname, int, int*...... )
}

Here the fnname has args it directly push into the stack.

The only solution that worked for me was this command :

docker-compose build --no-cache

This will automatically pull fresh image from repo and won't use the cache version that is prebuild with any parameters you've been using before.

Answer given by user @JPM and @usman are really very useful. It works fine but in my case it come in onReceive multiple time in my case 4 times so my code execute multiple time.

I do some modification and make as per my requirement and now it comes only 1 time

Here is java class for Broadcast.

public class WifiReceiver extends BroadcastReceiver {

String TAG = getClass().getSimpleName();
private Context mContext;

@Override
public void onReceive(Context context, Intent intent) {

    mContext = context;


    if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {

        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = cm.getActiveNetworkInfo();

                networkInfo.isConnected()) {
            // Wifi is connected
            WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
            WifiInfo wifiInfo = wifiManager.getConnectionInfo();
            String ssid = wifiInfo.getSSID();

        }
    }
    else if (intent.getAction().equalsIgnoreCase(WifiManager.WIFI_STATE_CHANGED_ACTION))
    {
        int wifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, WifiManager.WIFI_STATE_UNKNOWN);
        if (wifiState == WifiManager.WIFI_STATE_DISABLED)
        {
            Log.e(TAG, " ----- Wifi  Disconnected ----- ");
        }

    }
}
}

In AndroidManifest

<receiver android:name=".util.WifiReceiver" android:enabled="true">
        <intent-filter>
            <action android:name="android.net.wifi.WIFI_STATE_CHANGED" />
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
        </intent-filter>
    </receiver>


<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Another way to handle single and double quotes is:

function mssql_escape($str)
{
    if(get_magic_quotes_gpc())
    {
        $str = stripslashes($str);
    }
    return str_replace("'", "''", $str);
}

Some interesting alternatives:

OPTION 1

PrintStream p = System.out;
p.println("hello");

OPTION 2

PrintWriter p = new PrintWriter(System.out, true);
p.println("Hello");

When a semaphore is used to guard a critical region, there is no direct relationship between the semaphore and the data being protected. This is part of the reason why semaphores may be dispersed around the code, and why it is easy to forget to call wait or notify, in which case the result will be, respectively, to violate mutual exclusion or to lock the resource permanently.

In contrast, niehter of these bad things can happen with a monitor. A monitor is tired directly to the data (it encapsulates the data) and, because the monitor operations are atomic actions, it is impossible to write code that can access the data without calling the entry protocol. The exit protocol is called automatically when the monitor operation is completed.

A monitor has a built-in mechanism for condition synchronisation in the form of condition variable before proceeding. If the condition is not satisfied, the process has to wait until it is notified of a change in the condition. When a process is waiting for condition synchronisation, the monitor implementation takes care of the mutual exclusion issue, and allows another process to gain access to the monitor.

Is this what you're asking for?

int[] numbers = { 1, 2, 3 };
numbers.ToList().ForEach(n => Console.WriteLine(n));

A good thing to remember are these simple rules, and they apply to both parameters and return types...

• Value - makes a copy of the item in question.
• Pointer - refers to the address of the item in question.
• Reference - is literally the item in question.

There is a time and place for each, so make sure you get to know them. Local variables, as you've shown here, are just that, limited to the time they are locally alive in the function scope. In your example having a return type of int* and returning &i would have been equally incorrect. You would be better off in that case doing this...

void func1(int& oValue)
{
    oValue = 1;
}

Doing so would directly change the value of your passed in parameter. Whereas this code...

void func1(int oValue)
{
    oValue = 1;
}

would not. It would just change the value of oValue local to the function call. The reason for this is because you'd actually be changing just a "local" copy of oValue, and not oValue itself.

Disclaimer: I'm the author of the mentioned package.

I was surprised how the top answers to this question in 2019 still use serialization or reflection.

Serialization is limiting (requires attributes, specific constructors, etc.) and is very slow

BinaryFormatter requires the Serializable attribute, JsonConverter requires a parameterless constructor or attributes, neither handle read only fields or interfaces very well and both are 10-30x slower than necessary.

Expression Trees

You can instead use Expression Trees or Reflection.Emit to generate cloning code only once, then use that compiled code instead of slow reflection or serialization.

Having come across the problem myself and seeing no satisfactory solution, I decided to create a package that does just that and works with every type and is a almost as fast as custom written code.

You can find the project on GitHub: https://github.com/marcelltoth/ObjectCloner

Usage

You can install it from NuGet. Either get the ObjectCloner package and use it as:

var clone = ObjectCloner.DeepClone(original);

or if you don't mind polluting your object type with extensions get ObjectCloner.Extensions as well and write:

var clone = original.DeepClone();

Performance

A simple benchmark of cloning a class hierarchy showed performance ~3x faster than using Reflection, ~12x faster than Newtonsoft.Json serialization and ~36x faster than the highly suggested BinaryFormatter.

Using Set and converting it to an array is very similar to copying an Array...

So you can use the same methods for copying an array which is very easy in ES6

For example, you can use ...

Imagine you have this Set below:

const a = new Set(["Alireza", "Dezfoolian", "is", "a", "developer"]);

You can simply convert it using:

const b = [...a];

and the result is:

["Alireza", "Dezfoolian", "is", "a", "developer"]

An array and now you can use all methods that you can use for an array...

Other common ways of doing it:

const b = Array.from(a);

or using loops like:

const b = [];
a.forEach(v => b.push(v));

java.util.Date date = ...
DateTime dateTime = new DateTime(date);

Make sure date isn't null, though, otherwise it acts like new DateTime() - I really don't like that.

I had a similar problem and I ended up writing a node extension for this. You can check out the git repository. It's open source and free and all that good stuff !

https://github.com/aponxi/npm-execxi

ExecXI is a node extension written in C++ to execute shell commands one by one, outputting the command's output to the console in real-time. Optional chained, and unchained ways are present; meaning that you can choose to stop the script after a command fails (chained), or you can continue as if nothing has happened !

Usage instructions are in the ReadMe file. Feel free to make pull requests or submit issues!

EDIT: However it doesn't return the stdout yet... Just outputs them in real-time. It does now. Well, I just released it today. Maybe we can build on it.

Anyway, I thought it was worth to mention it.

In Android for certain functionalities you need to add the permission to the Manifest file.

1. Go to the Projects AndroidManifest.xml
2. Click on the Permissions Tab
3. Click on Add
4. Select Uses Permission
5. See the snapshot below

6.Save the manifest file and then run your project. Your project now should run as expected.

This should works

$token = "YOUR_BEARER_AUTH_TOKEN";
//setup the request, you can also use CURLOPT_URL
$ch = curl_init('API_URL');

// Returns the data/output as a string instead of raw data
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//Set your auth headers
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
   'Content-Type: application/json',
   'Authorization: Bearer ' . $token
   ));

// get stringified data/output. See CURLOPT_RETURNTRANSFER
$data = curl_exec($ch);

// get info about the request
$info = curl_getinfo($ch);
// close curl resource to free up system resources
curl_close($ch);

**old_list = [[0,1,'f'], [4,2,'t'],[9,4,'afsd']]
    #let's assume we want to sort lists by last value ( old_list[2] )
    new_list = sorted(old_list, key=lambda x: x[2])**

correct me if i'm wrong but isnt the 'x[2]' calling the 3rd item in the list, not the 3rd item in the nested list? should it be x[2][2]?

The "table-column" display type means it acts like the <col> tag in HTML - i.e. an invisible element whose width* governs the width of the corresponding physical column of the enclosing table.

See the W3C standard for more information about the CSS table model.

* And a few other properties like borders, backgrounds.

In Python, += is sugar coating for the __iadd__ special method, or __add__ or __radd__ if __iadd__ isn't present. The __iadd__ method of a class can do anything it wants. The list object implements it and uses it to iterate over an iterable object appending each element to itself in the same way that the list's extend method does.

Here's a simple custom class that implements the __iadd__ special method. You initialize the object with an int, then can use the += operator to add a number. I've added a print statement in __iadd__ to show that it gets called. Also, __iadd__ is expected to return an object, so I returned the addition of itself plus the other number which makes sense in this case.

>>> class Adder(object):
        def __init__(self, num=0):
            self.num = num

        def __iadd__(self, other):
            print 'in __iadd__', other
            self.num = self.num + other
            return self.num

>>> a = Adder(2)
>>> a += 3
in __iadd__ 3
>>> a
5

Hope this helps.

To get current date/time in javascript:

var date = new Date();

If you need milliseconds for easy server-side interpretation use

var value = date.getTime();

For formatting dates into a user readable string see this

Then just write to hidden field:

document.getElementById("DATE").value = value;

try

$('#xxx').attr('disabled', true);

It’s quite common to define navigational properties in a model to be virtual. When a navigation property is defined as virtual, it can take advantage of certain Entity Framework functionality. The most common one is lazy loading.

Lazy loading is a nice feature of many ORMs because it allows you to dynamically access related data from a model. It will not unnecessarily fetch the related data until it is actually accessed, thus reducing the up-front querying of data from the database.

From book "ASP.NET MVC 5 with Bootstrap and Knockout.js"

I ran into the same issue while trying to build a very old copy of omniORB on a CentOS 7 machine. Resolved the issue by installing the python development libraries:

# yum install python-devel

This installed the Python.h into:

/usr/include/python2.7/Python.h

TL;DR : Use StratifiedShuffleSplit with test_size=0.25

Scikit-learn provides two modules for Stratified Splitting:

1. StratifiedKFold : This module is useful as a direct k-fold cross-validation operator: as in it will set up n_folds training/testing sets such that classes are equally balanced in both.

Heres some code(directly from above documentation)

>>> skf = cross_validation.StratifiedKFold(y, n_folds=2) #2-fold cross validation
>>> len(skf)
2
>>> for train_index, test_index in skf:
...    print("TRAIN:", train_index, "TEST:", test_index)
...    X_train, X_test = X[train_index], X[test_index]
...    y_train, y_test = y[train_index], y[test_index]
...    #fit and predict with X_train/test. Use accuracy metrics to check validation performance

2. StratifiedShuffleSplit : This module creates a single training/testing set having equally balanced(stratified) classes. Essentially this is what you want with the n_iter=1. You can mention the test-size here same as in train_test_split

Code:

>>> sss = StratifiedShuffleSplit(y, n_iter=1, test_size=0.5, random_state=0)
>>> len(sss)
1
>>> for train_index, test_index in sss:
...    print("TRAIN:", train_index, "TEST:", test_index)
...    X_train, X_test = X[train_index], X[test_index]
...    y_train, y_test = y[train_index], y[test_index]
>>> # fit and predict with your classifier using the above X/y train/test

Use os.path.join to combine the path to the Documents directory with the completeName (filename?) supplied by the user.

import os
with open(os.path.join('/path/to/Documents',completeName), "w") as file1:
    toFile = raw_input("Write what you want into the field")
    file1.write(toFile)

If you want the Documents directory to be relative to the user's home directory, you could use something like:

os.path.join(os.path.expanduser('~'),'Documents',completeName)

Others have proposed using os.path.abspath. Note that os.path.abspath does not resolve '~' to the user's home directory:

In [10]: cd /tmp
/tmp

In [11]: os.path.abspath("~")
Out[11]: '/tmp/~'

Install HookyQR.beautify extension. It will beautify your javascript, JSON, CSS, Sass, and HTML in Visual Studio Code. It is the most use extensions for this purpose

For delays as large as one minute, sleep() is a nice choice.

If someday, you want to pause on delays smaller than one second, you may want to consider poll() with a timeout.

Both are POSIX.

Other solutions posted above produce a retain cycle due to the textfield map. Besides, the maxLength property should be nullable if not set instead of artificial Int.max constructions; and the target will be set multiple times if maxLength is changed.

Here an updated solution for Swift4 with a weak map to prevent memory leaks and the other fixes

private var maxLengths = NSMapTable<UITextField, NSNumber>(keyOptions: NSPointerFunctions.Options.weakMemory, valueOptions: NSPointerFunctions.Options.strongMemory)

extension UITextField {

    var maxLength: Int? {
        get {
            return maxLengths.object(forKey: self)?.intValue
        }
        set {
            removeTarget(self, action: #selector(limitLength), for: .editingChanged)
            if let newValue = newValue {
                maxLengths.setObject(NSNumber(value: newValue), forKey: self)
                addTarget(self, action: #selector(limitLength), for: .editingChanged)
            } else {
                maxLengths.removeObject(forKey: self)
            }
        }
    }

    @IBInspectable var maxLengthInspectable: Int {
        get {
            return maxLength ?? Int.max
        }
        set {
            maxLength = newValue
        }
    }

    @objc private func limitLength(_ textField: UITextField) {
        guard let maxLength = maxLength, let prospectiveText = textField.text, prospectiveText.count > maxLength else {
            return
        }
        let selection = selectedTextRange
        text = String(prospectiveText[..<prospectiveText.index(from: maxLength)])
        selectedTextRange = selection
    }
}

What about:

char *string = "qwerty";
char *e = string;
int idx = 0;
while (*e++ != 'e') idx++;

copying to e to preserve the original string, I suppose if you don't care you could just operate over *string

([FromBody] IDictionary<string,object> data)

Use the Javascript string split() function.

var coolVar = '123-abc-itchy-knee';
var partsArray = coolVar.split('-');

// Will result in partsArray[0] == '123', partsArray[1] == 'abc', etc

It seems I misread the question, but for reference, you can extract a range of the DOM (not to the clipboard; compatible with all modern browsers), and combine it with the oncopy, onpaste, and onbeforepaste events to get the clipboard behaviour. Here's the code to achieve this:

function clipBoard(sCommand) {
  var oRange = contentDocument.createRange();
  oRange.setStart(startNode, startOffset);
  oRange.setEnd(endNode, endOffset);

  /* This is where the actual selection happens.
     in the above, startNode and endNode are
     DOM nodes defining the beginning and
     end of the "selection" respectively.

     startOffset and endOffset are constants
     that are defined as follows:

         END_TO_END: 2
         END_TO_START: 3
         NODE_AFTER: 1
         NODE_BEFORE: 0
         NODE_BEFORE_AND_AFTER: 2
         NODE_INSIDE: 3
         START_TO_END: 1
         START_TO_START: 0

     And it would be used like oRange.START_TO_END
  */

  switch(sCommand) {

    case "cut":
      this.oFragment = oRange.extractContents();
      oRange.collapse();
      break;

    case "copy":
      this.oFragment = oRange.cloneContents();
      break;

    case "paste":
      oRange.deleteContents();
      var cloneFragment = this.oFragment.cloneNode(true)
      oRange.insertNode(cloneFragment);
      oRange.collapse();
      break;
  }
}

Yes it is implementable!

This will do it recursively for you:

find /path/to/base/dir/* -type d -ctime +10 -exec rm -rf {} \;

Explanation:

• find: the unix command for finding files / directories / links etc.
• /path/to/base/dir: the directory to start your search in.
• -type d: only find directories
• -ctime +10: only consider the ones with modification time older than 10 days
• -exec ... \;: for each such result found, do the following command in ...
• rm -rf {}: recursively force remove the directory; the {} part is where the find result gets substituted into from the previous part.

Alternatively, use:

find /path/to/base/dir/* -type d -ctime +10 | xargs rm -rf

Which is a bit more efficient, because it amounts to:

rm -rf dir1 dir2 dir3 ...

as opposed to:

rm -rf dir1; rm -rf dir2; rm -rf dir3; ...

as in the -exec method.

With modern versions of find, you can replace the ; with + and it will do the equivalent of the xargs call for you, passing as many files as will fit on each exec system call:

find . -type d -ctime +10 -exec rm -rf {} +

The accepted answer works, but you have to do a "Select All" first -- every time -- and I'm way too lazy for that.

And it turns out, it's not super trivial -- I figured I'd post this here in an attempt to save like-minded individuals the 30 minutes it takes to track all this down. -- Also note: this approach restores the original selection when it's done (and it happens so fast, you don't even notice the selection was ever changed).

1.) First, add a custom command to your init script (File->Open Your Init Script, then paste this at the bottom):

atom.commands.add 'atom-text-editor', 'custom:reformat', ->
    editor = atom.workspace.getActiveTextEditor();
    oldRanges = editor.getSelectedBufferRanges();
    editor.selectAll();
    atom.commands.dispatch(atom.views.getView(editor), 'editor:auto-indent')
    editor.setSelectedBufferRanges(oldRanges);

2.) Bind "custom:reformat" to a key (File->Open Your Keymap, then paste this at the bottom):

'atom-text-editor':
    'ctrl-alt-d': 'custom:reformat'

3.) Restart Atom (the init.coffee script only runs when atom is first launched).

select * from tbl where (endDate>=@starDate and startDate<=@endDate)

attached the diagram for explanation

storing simple data in DB StartDate =10/01/2020 and endDate=20/01/2020. user can provide @startDate(d1) and @endDate(d2) to search.

here 6 scenarios can happen depicted by the 4 red lines (match data) 2 green lines (no match data).

so by conclusion from the image, to get data from DB by providing d1,d2. ED must be greater than d1(@startDate) and SD must be less than d2(@endDate).

Here is a simple snippet that read's in a json text file from a dictionary. Note that your json file must follow the json standard, so it has to have " double quotes rather then ' single quotes.

Your JSON dump.txt File:

{"test":"1", "test2":123}

Python Script:

import json
with open('/your/path/to/a/dict/dump.txt') as handle:
    dictdump = json.loads(handle.read())

I'd really recommend Scrapy.

Quote from a deleted answer:

• Scrapy crawling is fastest than mechanize because uses asynchronous operations (on top of Twisted).
• Scrapy has better and fastest support for parsing (x)html on top of libxml2.
• Scrapy is a mature framework with full unicode, handles redirections, gzipped responses, odd encodings, integrated http cache, etc.
• Once you are into Scrapy, you can write a spider in less than 5 minutes that download images, creates thumbnails and export the extracted data directly to csv or json.

Many thanks for the information about using the QueryDefs collection! I have been wondering about this for a while.

I did it a different way, without using VBA, by using a table containing the query parameters.

E.g:

SELECT a_table.a_field 
FROM QueryParameters, a_table 
WHERE a_table.a_field BETWEEN QueryParameters.a_field_min 
AND QueryParameters.a_field_max

Where QueryParameters is a table with two fields, a_field_min and a_field_max

It can even be used with GROUP BY, if you include the query parameter fields in the GROUP BY clause, and the FIRST operator on the parameter fields in the HAVING clause.

  if (status == 'OK') {

Or refer to the documentation https://developers.google.com/maps/documentation/javascript/geocoding

As long as your List is a concrete class, you can simply call the contains() method as long as you have implemented your equals() method on MyItem.

// given 
// some input ... you to complete

// when
List<MyItems> results = service.getMyItems();

// then
assertTrue(results.contains(new MyItem("foo")));
assertTrue(results.contains(new MyItem("bar")));

Assumes you have implemented a constructor that accepts the values you want to assert on. I realise this isn't on a single line, but it's useful to know which value is missing rather than checking both at once.

Assuming that you want to group the data before you generate the key with the sequence, it sounds like you want something like

INSERT INTO HISTORICAL_CAR_STATS (
    HISTORICAL_CAR_STATS_ID, 
    YEAR,
    MONTH, 
    MAKE,
    MODEL,
    REGION,
    AVG_MSRP,
    CNT) 
SELECT MY_SEQ.nextval,
       year,
       month,
       make,
       model,
       region,
       avg_msrp,
       cnt
  FROM (SELECT '2010' year,
               '12' month,
               'ALL' make,
               'ALL' model,
               REGION,
               sum(AVG_MSRP*COUNT)/sum(COUNT) avg_msrp,
               sum(cnt) cnt
          FROM HISTORICAL_CAR_STATS
         WHERE YEAR = '2010' 
           AND MONTH = '12'
           AND MAKE != 'ALL' 
         GROUP BY REGION)

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

Probably you use Microsoft SQL Server which support Common Table Expressions (CTE) (see http://msdn.microsoft.com/en-us/library/ms190766.aspx) which are very friendly for query optimization. So I suggest you my favor construction:

WITH GetNumberOfPlans(Id,NumberOfPlans) AS (
    SELECT tableA.Id, COUNT(tableC.Id)
    FROM tableC
        RIGHT OUTER JOIN tableA ON tableC.tableAId = tableA.Id
    GROUP BY tableA.Id
),GetUserInformation(Id,Name,Owner,ImageUrl,
                     CompanyImageUrl,NumberOfUsers) AS (
    SELECT tableA.Id, tableA.Name, tableB.Username AS Owner, tableB.ImageUrl,
        tableB.CompanyImageUrl,COUNT(tableD.UserId),p.NumberOfPlans
    FROM tableA
        INNER JOIN tableB ON tableB.Id = tableA.Owner
        RIGHT OUTER JOIN tableD ON tableD.tableAId = tableA.Id
    GROUP BY tableA.Name, tableB.Username, tableB.ImageUrl, tableB.CompanyImageUrl
)
SELECT u.Id,u.Name,u.Owner,u.ImageUrl,u.CompanyImageUrl
    ,u.NumberOfUsers,p.NumberOfPlans
FROM GetUserInformation AS u
    INNER JOIN GetNumberOfPlans AS p ON p.Id=u.Id

After some experiences with CTE you will be find very easy to write code using CTE and you will be happy with the performance.

Lines beginning with a # are preprocessor directives. #if 0 [...] #endif blocks do not make it to the compiler and will generate no machine code.

You can demonstrate what happens with the preprocessor with a source file ifdef.cxx:

#if 0
This code will not be compiled
#else
int i = 0;
#endif

Running gcc -E ifdef.cxx will show you what gets compiled.

You may choose to use this mechanism to prevent a block of code being compiled during the development cycle, but you would probably not want to check it in to your source control as it just adds cruft to your code and reduces readability. If it's a historical piece of code that has been commented out, then it should be removed: source control contains the history, right?

Also, the answer may be the same for both C and C++ but there is no language called C/C++ and it's not a good habit to refer to such a language.

from pyspark.sql.types import IntegerType
data_df = data_df.withColumn("Plays", data_df["Plays"].cast(IntegerType()))
data_df = data_df.withColumn("drafts", data_df["drafts"].cast(IntegerType()))

You can run loop for each column but this is the simplest way to convert string column into integer.

use a trigges it will work:-

->CREATE TRIGGER trigger_name BEFORE INSERT ON table_name

FOR EACH ROW SET NEW.column_name3 = NEW.column_name1 + NEW.column_name2;

this will only work only when you will insert a row in table not when you will be updating your table for such a pupose create another trigger of different name and use UPDATE on the place of INSERT in the above syntax

There is an api in Express.

res.sendFile

app.get('/report/:chart_id/:user_id', function (req, res) {
    // res.sendFile(filepath);
});

You can use cut with a delimiter like this:

with space delim:

cut -d " " -f1-100,1000-1005 infile.csv > outfile.csv

with tab delim:

cut -d$'\t' -f1-100,1000-1005 infile.csv > outfile.csv

I gave you the version of cut in which you can extract a list of intervals...

Hope it helps!

I've seen GCC turn the conditional operator into cmov (conditional move) instructions, while turning if statements into branches, which meant in our case, the code was faster when using the conditional operator. But that was a couple of years ago, and most likely today, both would compile to the same code.

There's no guarantee that they'll compile to the same code. If you need the performance then, as always, measure. And when you've measured and found out that 1. your code is too slow, and 2. it is this particular chunk of code that is the culprit, then study the assembly code generated by the compiler and check for yourself what is happening.

Don't trust golden rules like "the compiler will always generate more efficient code if I use the conditional operator".

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

int main () {
  ofstream file;
  file.open ("codebind.txt");
  file << "Please writr this text to a file.\n this text is written using C++\n";
  file.close();
  return 0;
}

import numpy as np

myList = np.linspace(0, 100, 1000) #Generates 1000 numbers from 0 to 100 in equal intervals

I recently stumbled upon this great Gist that gives a working implementation of a drag sort ListView, with no external dependencies needed.

Basically it consists on creating your custom Adapter extending ArrayAdapter as an inner class to the activity containing your ListView. On this adapter one then sets an onTouchListener to your List Items that will signal the start of the drag.

In that Gist they set the listener to a specific part of the layout of the List Item (the "handle" of the item), so one does not accidentally move it by pressing any part of it. Personally, I preferred to go with an onLongClickListener instead, but that is up to you to decide. Here an excerpt of that part:

public class MyArrayAdapter extends ArrayAdapter<String> {

    private ArrayList<String> mStrings = new ArrayList<String>();
    private LayoutInflater mInflater;
    private int mLayout;

    //constructor, clear, remove, add, insert...

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        ViewHolder holder;

        View view = convertView;
        //inflate, etc...

        final String string = mStrings.get(position);
        holder.title.setText(string);

        // Here the listener is set specifically to the handle of the layout
        holder.handle.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) {
                    startDrag(string);
                    return true;
                }
                return false;
            }
        });

        // change color on dragging item and other things...         

        return view;
    }
}

This also involves adding an onTouchListener to the ListView, which checks if an item is being dragged, handles the swapping and invalidation, and stops the drag state. An excerpt of that part:

mListView.setOnTouchListener(new View.OnTouchListener() {
     @Override
     public boolean onTouch(View view, MotionEvent event) {
        if (!mSortable) { return false; }
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN: {
                break;
            }
            case MotionEvent.ACTION_MOVE: {
                // get positions
                int position = mListView.pointToPosition((int) event.getX(), 
                    (int) event.getY());
                if (position < 0) {
                    break;
                }
                // check if it's time to swap
                if (position != mPosition) {
                    mPosition = position;
                    mAdapter.remove(mDragString);
                    mAdapter.insert(mDragString, mPosition);
                }
                return true;
            }
            case MotionEvent.ACTION_UP:
            case MotionEvent.ACTION_CANCEL:
            case MotionEvent.ACTION_OUTSIDE: {
                //stop drag state
                stopDrag();
                return true;
            }
        }
        return false;
    }
});

Finally, here is how the stopDrag and startDrag methods look like, which handle the enabling and disabling of the drag process:

public void startDrag(String string) {
    mPosition = -1;
    mSortable = true;
    mDragString = string;
    mAdapter.notifyDataSetChanged();
}

public void stopDrag() {
    mPosition = -1;
    mSortable = false;
    mDragString = null;
    mAdapter.notifyDataSetChanged();
}

Try setting a custom CultureInfo for CurrentCulture and CurrentUICulture:

Globalization.CultureInfo customCulture = new Globalization.CultureInfo("en-US", true);

customCulture.DateTimeFormat.ShortDatePattern = "yyyy-MM-dd h:mm tt";

System.Threading.Thread.CurrentThread.CurrentCulture = customCulture;
System.Threading.Thread.CurrentThread.CurrentUICulture = customCulture;

DateTime newDate = System.Convert.ToDateTime(DateTime.Now.ToString("yyyy-MM-dd h:mm tt"));

To solve the issue try to repair the .net framework 4 and then run the command

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

My approach would not be to start by writing your own API. Life's too short, and there are more pressing problems to solve. In this situation, I typically:

• Find a library that appears to do what I want. If one doesn't exist, then implement it.
• If a library does exist, but I'm not sure it'll be suitable for my needs, write a thin adapter API around it, so I can control how it's called. The adapter API expresses the API I need, and it maps those calls to the underlying API.
• If the library doesn't turn out to be suitable, I can swap another one in underneath the adapter API (whether it's another open source one or something I write myself) with a minimum of effort, without affecting the callers.

Start with something someone has already written. Odds are, it'll do what you want. You can always write your own later, if necessary. OpenCSV is as good a starting point as any.

Yes there is. The preferred syntax is to favor str.format over the deprecated % operator.

print "First number is {} and second number is {}".format(first, second)

To get actual hour, minute and seconds as appear on watch try this code

val sec = (milliSec/1000) % 60
val min = ((milliSec/1000) / 60) % 60
val hour = ((milliSec/1000) / 60) / 60

there is one more option, sys.stdout.write returns None, which keep the list empty

cat somefile.log|python -c "import sys;[line for line in sys.stdin if sys.stdout.write(line*2)]"

In my case I wanted to switch from http to https, so I had deleted http from IIS. In my .csproj.user file found that I still had:

<IISUrl>http://localhost/</IISUrl>

So I changed it to:

<IISUrl>https://localhost/</IISUrl>

You can delete all breakpoints using

del <start_breakpoint_num> - <end_breakpoint_num>

To view the start_breakpoint_num and end_breakpoint_num use:

info break

If you initialize in the top or in constructor it doesn't make much difference .But in some case initializing in constructor makes sense.

class String
{
    char[] arr/*=char [20]*/; //Here initializing char[] over here will not make sense.
    String()
    {
        this.arr=new char[0];
    }
    String(char[] arr)
    {
        this.arr=arr;
    }
}

So depending on the situation sometime you will have to initialize in the top and sometimes in a constructor.

FYI other option's for initialization without using a constructor :

class Foo
{
    int i;
    static int k;

    //instance initializer block
    {
        //run's every time a new object is created
        i=20;
    }

    //static initializer block
    static{
        //run's only one time when the class is loaded
        k=18;
    }    
} 

You can add a CSS class of cancel to a submit button to suppress the validation

e.g

<input class="cancel" type="submit" value="Save" />

See the jQuery Validator documentation of this feature here: Skipping validation on submit

EDIT:

The above technique has been deprecated and replaced with the formnovalidate attribute.

<input formnovalidate="formnovalidate" type="submit" value="Save" />

Doing this works for me:

moment(new Date("27/04/2016")).format

you can also get random number from awk

awk 'BEGIN {
   # seed
   srand()
   for (i=1;i<=1000;i++){
     print int(1 + rand() * 100)
   }
}'

You can create a custom class GradientView:

Swift 5

class GradientView: UIView {
    override open class var layerClass: AnyClass {
       return CAGradientLayer.classForCoder()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        let gradientLayer = layer as! CAGradientLayer
        gradientLayer.colors = [UIColor.white.cgColor, UIColor.black.cgColor]
    }
}

In the storyboard, set the class type to any view that you want to have gradient background:

This is better in the following ways:

• No need to set frame of CLayer
• Use NSConstraint as usual on the UIView
• Don't need to create sublayers (less memory use)

You can also do this:

var list = $('#items')[0]; // HTMLSelectElement
$.each(numbers, function(index, text) { 
    list.options[list.options.length] = new Option(index, text);
}); 

use this

if (userProfile.AccountType == AccountType.Retailer)
{
     ...
}

If you want to get int from your AccountType enum and compare it (don't know why) do this:

if((int)userProfile.AccountType == 1)
{ 
     ...
}

Objet reference not set to an instance of an object exception is because your userProfile is null and you are getting property of null. Check in debug why it's not set.

EDIT (thanks to @Rik and @KonradMorawski) :

Maybe you can do some check before:

if(userProfile!=null)
{
}

or

if(userProfile==null)
{
   throw new ArgumentNullException(nameof(userProfile)); // or any other exception
}

This issue can be resolved by setting the higher values for the MySQL variable innodb_buffer_pool_size. The default value for innodb_buffer_pool_size will be 8,388,608.

To change the settings value for innodb_buffer_pool_size please see the below set.

1. Locate the file my.cnf from the server. For Linux servers this will be mostly at /etc/my.cnf
2. Add the line innodb_buffer_pool_size=64MB to this file
3. Restart the MySQL server

To restart the MySQL server, you can use anyone of the below 2 options:

1. service mysqld restart
2. /etc/init.d/mysqld restart

Reference The total number of locks exceeds the lock table size

They way I did it was by selecting all of the data

select * from myTable and then right-clicking on the result set and chose "Save results as..." a csv file.

Opening the csv file in Notepad++ I saw the LF characters not visible in SQL Server result set.

model.find({Branch:branch},function (err, docs){
  if (err) res.send(err)

  res.send(JSON.parse(JSON.stringify(docs)))
});

Here is an easy way to do so using HTMLBuilder

    myTextView.setText(new HtmlBuilder().
                    open(HtmlBuilder.Type.BOLD).
                    append("Some bold text ").
                    close(HtmlBuilder.Type.BOLD).
                    open(HtmlBuilder.Type.ITALIC).
                    append("Some italic text").
                    close(HtmlBuilder.Type.ITALIC).
                    build()
    );

Result:

Some bold text Some italic text

Unfortunately, MySQL does not explicitly support that (except for dumping and reloading database again).

From http://dev.mysql.com/doc/refman/5.1/en/rename-database.html:

13.1.32. RENAME DATABASE Syntax

RENAME {DATABASE | SCHEMA} db_name TO new_db_name;

This statement was added in MySQL 5.1.7 but was found to be dangerous and was removed in MySQL 5.1.23. ... Use of this statement could result in loss of database contents, which is why it was removed. Do not use RENAME DATABASE in earlier versions in which it is present.

A real literal suffixed by M or m is of type decimal (money). For example, the literals 1m, 1.5m, 1e10m, and 123.456M are all of type decimal. This literal is converted to a decimal value by taking the exact value, and, if necessary, rounding to the nearest representable value using banker's rounding. Any scale apparent in the literal is preserved unless the value is rounded or the value is zero (in which latter case the sign and scale will be 0). Hence, the literal 2.900m will be parsed to form the decimal with sign 0, coefficient 2900, and scale 3.

I'm not sure about g++, but if you're using GNU Make then "make -j N" (where N is the number of threads make can create) will allow make to run multple g++ jobs at the same time (so long as the files do not depend on each other).

It's actually a sensible question. Here's the answer from Excel 2010 help:

"The Workbook object is a member of the Workbooks collection. The Workbooks collection contains all the Workbook objects currently open in Microsoft Excel."

So, since that workbook isn't open - at least I assume it isn't - it can't be set as a workbook object. If it was open you'd just set it like:

Set wbk = workbooks("Master Benchmark Data Sheet.xlsx")

Another option, related to Kevin's, is use __FILE__, but instead replace the php file name from within it:

<?php

$docRoot = str_replace($_SERVER['SCRIPT_NAME'], '', __FILE__);
require_once($docRoot . '/lib/include.php');

?>

I've been using this for a while. The only problem is sometimes you don't have $_SERVER['SCRIPT_NAME'], but sometimes there is another variable similar.

you can add this code to web.config in asp mvc

   <system.webServer>
    <staticContent>
      <remove fileExtension=".srt" />
      <mimeMap fileExtension=".srt" mimeType="text/srt" />
      <remove fileExtension=".vtt" />
      <mimeMap fileExtension=".vtt" mimeType="text/vtt" />
    </staticContent>
  </system.webServer>

you can change file extension with your file extension

I got this error fatal error lnk1104: cannot open file 'kernel32.lib'. this error is getting because there is no path in VC++ directories. To solve this problem

Open Visual Studio 2008

1. go to Tools-options-Projects and Solutions-VC++ directories-*
2. then at right corner select Library files
3. here you need to add path of kernel132.lib

In my case It is C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib

So the answer seems to be to NOT use the Solution Explorer search box.

Rather, open any file in the solution, then use the control-f search pop-up to search all files by:

1. selecting "Find All" from the "--> Find Next / <-- Find Previous" selector
2. selecting "Current Project" or "Entire Solution" from the selector that normally says just "Current Document".

Because of the One Definition Rule (probably¹).

In C++, each non-inline object and function must have exactly one definition within the program. By #includeing the file in which foo(int) is defined (the CPP file), it is defined both in every file where foop.cpp is #included, and in foop.cpp itself (assuming foop.cpp is compiled).

You can make a function inline to override this behavior, but I'm not recommending that here. I have never seen a situation where it is necessary or even desirable to #include a CPP file.

There are situations where it is desireable to include a definition of something. This is specially true when you try to seperate the definition of a template from the declaration of it. In those cases, I name the file HPP rather than CPP to denote the difference.

¹: "(probably)" I say probably here because the actual code you've posted should compile without errors, but given the compiler error it seems likely that the code you posted isn't exactly the same as the code you're compiling.

You can't use a foreach statement for that. The foreach is using internally an iterator:

The iterators returned by this class's iterator and listIterator methods are fail-fast: if the list is structurally modified at any time after the iterator is created, in any way except through the iterator's own remove or add methods, the iterator will throw a ConcurrentModificationException.

(From ArrayList javadoc)

In the foreach statement you don't have access to the iterator's add method and in any case that's still not the type of add that you want because it does not append at the end. You'll need to traverse the list manually:

int listSize = list.size();
for(int i = 0; i < listSize; ++i)
  list.add("whatever");

Note that this is only efficient for Lists that allow random access. You can check for this feature by checking whether the list implements the RandomAccess marker interface. An ArrayList has random access. A linked list does not.

Not sure if this is still relevant but I had to write straight to a json file and I came up with the following piecing several stackoverflow answers together

public class LowercaseJsonSerializer
{
    private static readonly JsonSerializerSettings Settings = new JsonSerializerSettings
    {
        ContractResolver = new LowercaseContractResolver()
    };

    public static void Serialize(TextWriter file, object o)
    {
        JsonSerializer serializer = new JsonSerializer()
        {
            ContractResolver = new LowercaseContractResolver(),
            Formatting = Formatting.Indented,
            NullValueHandling = NullValueHandling.Ignore
        };
        serializer.Converters.Add(new Newtonsoft.Json.Converters.StringEnumConverter());
        serializer.Serialize(file, o);
    }

    public class LowercaseContractResolver : DefaultContractResolver
    {
        protected override string ResolvePropertyName(string propertyName)
        {
            return Char.ToLowerInvariant(propertyName[0]) + propertyName.Substring(1);
        }
    }
}

It assures all my json keys are lowercase starting according to json "rules". Formats it cleanly indented and ignores nulls in the output. Aslo by adding a StringEnumConverter it prints enums with their string value.

Personally I find this the cleanest I could come up with, without having to dirty the model with annotations.

usage:

    internal void SaveJson(string fileName)
    {
        // serialize JSON directly to a file
        using (StreamWriter file = File.CreateText(@fileName))
        {
            LowercaseJsonSerializer.Serialize(file, jsonobject);
        }
    }

The code posted by Owen can tell you the information mentioned by a number of the other answers here:

public void simpleExample ()
{
    FileInputStream fis = new FileInputStream ("mytest.class");
    parseJavaClassFile ( fis );
}
protected void parseJavaClassFile ( InputStream classByteStream ) throws Exception
{
    DataInputStream dataInputStream = new DataInputStream ( classByteStream );
    magicNumber = dataInputStream.readInt();
    if ( magicNumber == 0xCAFEBABE )
    {
        int minorVer = dataInputStream.readUnsignedShort();
        int majorVer = dataInputStream.readUnsignedShort();
        // do something here with major & minor numbers
    }
}

See also this and this site. I ended up modifying the Mind Products code quickly to check what each of my dependencies was compiled for.

You probably want to look into the observer pattern.

Here's some sample code to get yourself started:

import java.util.*;

// An interface to be implemented by everyone interested in "Hello" events
interface HelloListener {
    void someoneSaidHello();
}

// Someone who says "Hello"
class Initiater {
    private List<HelloListener> listeners = new ArrayList<HelloListener>();

    public void addListener(HelloListener toAdd) {
        listeners.add(toAdd);
    }

    public void sayHello() {
        System.out.println("Hello!!");

        // Notify everybody that may be interested.
        for (HelloListener hl : listeners)
            hl.someoneSaidHello();
    }
}

// Someone interested in "Hello" events
class Responder implements HelloListener {
    @Override
    public void someoneSaidHello() {
        System.out.println("Hello there...");
    }
}

class Test {
    public static void main(String[] args) {
        Initiater initiater = new Initiater();
        Responder responder = new Responder();

        initiater.addListener(responder);

        initiater.sayHello();  // Prints "Hello!!!" and "Hello there..."
    }
}

The regular expression matches three patterns:

1. [A-Z]?[a-z]+: Consecutive lower-case letters that optionally start with an upper-case letter.
2. [A-Z]{2,}(?=[A-Z][a-z]|\d|\W|$): Two or more consecutive upper-case letters. It uses a lookahead to exclude the last upper-case letter if it is followed by a lower-case letter.
3. \d+: Consecutive numbers.

By using re.findall we get a list of individual "words" that can be converted to lower-case and joined with underscores.

Use string concatenation. Try this:

$('div[imageId="'+imageN +'"]').each(function() {
    $(this);   
});

You can use jquery for this:

$('body').bind('copy paste',function(e) {
    e.preventDefault(); return false; 
});

Using jQuery bind() and specififying your desired eventTypes .

Ehcache is a pretty good solution for this and has a way to peek (getQuiet() is the method) such that it doesn't update the idle timestamp. Internally, Ehcache is implemented with a set of maps, kind of like ConcurrentHashMap, so it has similar kinds of concurrency benefits.

In case anyone is running in a Spring Boot app, and you want to read the response body of a RestTemplate (which is why I want to read a stream twice), there is a clean(er) way of doing this.

First of all, you need to use Spring's StreamUtils to copy the stream to a String:

String text = StreamUtils.copyToString(response.getBody(), Charset.defaultCharset()))

But that's not all. You also need to use a request factory that can buffer the stream for you, like so:

ClientHttpRequestFactory factory = new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory());
RestTemplate restTemplate = new RestTemplate(factory);

Or, if you're using the factory bean, then (this is Kotlin but nevertheless):

@Bean
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
fun createRestTemplate(): RestTemplate = RestTemplateBuilder()
  .requestFactory { BufferingClientHttpRequestFactory(SimpleClientHttpRequestFactory()) }
  .additionalInterceptors(loggingInterceptor)
  .build()

You might need to do some checking. You cannot safely convert factors directly to numeric. as.character must be applied first. Otherwise, the factors will be converted to their numeric storage values. I would check each column with is.factor then coerce to numeric as necessary.

df1[] <- lapply(df1, function(x) {
    if(is.factor(x)) as.numeric(as.character(x)) else x
})
sapply(df1, class)
#         a         b 
# "numeric" "numeric" 

No - it doesn't matter in the slightest. On NT the .bat and .cmd extension both cause the cmd.exe processor to process the file in exactly the same way.

Additional interesting information about command.com vs. cmd.exe on WinNT-class systems from MS TechNet (http://technet.microsoft.com/en-us/library/cc723564.aspx):

This behavior reveals a quite subtle feature of Windows NT that is very important. The 16-bit MS-DOS shell (COMMAND.COM) that ships with Windows NT is specially designed for Windows NT. When a command is entered for execution by this shell, it does not actually execute it. Instead, it packages the command text and sends it to a 32-bit CMD.EXE command shell for execution. Because all commands are actually executed by CMD.EXE (the Windows NT command shell), the 16-bit shell inherits all the features and facilities of the full Windows NT shell.

It doesn't seem to trigger DocumentCompleted/Navigated events for external Javascript or CSS files, but it will for iframes. As PK says, compare the WebBrowserDocumentCompletedEventArgs.Url property (I don't have the karma to make a comment yet).

Here's another using the zip function.

Stevo is right, the meaning and usage of the dollar script sign (in Javascript and the jQuery platform, but not in PHP) is completely semantic. $ is a character that can be used as part of an identifier name. In addition, the dollar sign is perhaps not the most "weird" thing you can encounter in Javascript. Here are some examples of valid identifier names:

var _       = function() { alert("hello from _"); }
var \u0024  = function() { alert("hello from $ defined as u0024"); }
var Ø       = function() { alert("hello from Ø"); }
var $$$$$   = function() { alert("hello from $$$$$"); }

All of the examples above will work.

Try them.

In general using an interface allows you to vary the implementation with minimal collateral damage. Although java.lang.String are super popular it may be possible that in certain contexts one may want to use another implementation. By building the API around CharSequences rather than Strings the code gives one the opportunity to do that.

I think we can write this fewer styles, without changing the existing color. The following worked for me (in Bootstrap 3.2.0)

.navbar-nav > li > a { padding-top: 5px !important; padding-bottom: 5px !important; }
.navbar { min-height: 32px !important; }
.navbar-brand { padding-top: 5px; padding-bottom: 10px; padding-left: 10px; }

The last one ('navbar-brand') is actually needed only if you have text as your 'brand' name.

You can also do this with positioning, set parent div to relative and child div to absolute.

.wrapper {
      position: relative;
  }
.childDiv {
      position: absolute;
      left: 50%;
      transform: translateX(-50%);
  }

download your desired version of php binary from http://windows.php.net/download/ website. download Thread Safe binary zip version. Unzip the downloaded version of the PHP in a separate folder. Please make sure that your new php folder name is not "PHP". May be you can use filder name as the version name. For example for php 5.4 you can use php54.

Copy the new php folder into your xampp folder. Now go to yourxampp/apache/conf/extra folder. Open file httpd-xampp.conf from the folder extra. Change the following variables:

Variable PHPINIDir to be / Varaible LoadModule to be //php5apache2_2.dl

Save the file httpd-xampp.conf. Restart your XAMPP apache server. If your server get restarted successfully then your server php version is upgraded.

You miss the from clause

SELECT *  from TCCAWZTXD.TCC_COIL_DEMODATA WHERE CURRENT_INSERTTIME  BETWEEN(CURRENT_TIMESTAMP)-5 minutes AND CURRENT_TIMESTAMP

Delimiters, delimiters...

You really need them when there are multiple statements in your procedure. (in other words, do you have a ; in your code and then more statements/commands? Then, you need to use delimiters).

For such a simpler rpocedure as yours though, you could just do:

CREATE PROCEDURE ProG()
  SELECT * FROM `hs_hr_employee_leave_quota`;

It should be:

[mysqld]
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

instead of

[mysqld]
sql_mode="NO_ENGINE_SUBSTITUTION"

then restart mysqld service.

sed can perform text transformations on input stream from a file or from a pipeline. Example:

echo 'C:\foo\bar.xml' | sed 's/\\/\//g'

gets

C:/foo/bar.xml

Sometimes the reason of these errors are not the DataBinding itself, but some other part of our code. In my case I had an error in Room database so the compiler couldn't generate the binding classes and it gives me these errors.

According to Google:

Previous versions of the data binding compiler generated the binding classes in the same step that compiles your managed code. If your managed code fails to compile, you might get multiple errors reporting that the binding classes aren't found. The new data binding compiler prevents these errors by generating the binding classes before the managed compiler builds your app.

So to enable new data binding compiler, add the following option to your gradle.properties file:

android.databinding.enableV2=true

You can also enable the new compiler in your gradle command by adding the following parameter:

-Pandroid.databinding.enableV2=true

Note that the new compiler in Android Studio version 3.2 is enabled by default.

The design of your classes will make it hard to test them. Using hardcoded connection strings or instantiating collaborators in your methods with new can be considered as test-antipatterns. Have a look at the DependencyInjection pattern. Frameworks like Spring might be of help here.

To have your DAO tested you need to have control over your database connection in your unit tests. So the first thing you would want to do is extract it out of your DAO into a class that you can either mock or point to a specific test database, which you can setup and inspect before and after your tests run.

A technical solution for testing db/DAO code might be dbunit. You can define your test data in a schema-less XML and let dbunit populate it in your test database. But you still have to wire everything up yourself. With Spring however you could use something like spring-test-dbunit which gives you lots of leverage and additional tooling.

As you call yourself a total beginner I suspect this is all very daunting. You should ask yourself if you really need to test your database code. If not you should at least refactor your code, so you can easily mock out all database access. For mocking in general, have a look at Mockito.

Very easy, forget CSS targeting the input["type"] thing, it doesn't work for me. I don't know why. I got my solution in my HTML tag

If Ragnar's answer doesn't work for you. Here is probably why (based on my experience) -

1. I wasn't using node-mysql package as shown my Ragnar. I was using mysql package. They're different (if you didn't notice - just like me). But I'm not sure if it has anything to do with the ? not working, since it seemed to work for many folks using the mysql package.

2. Try using a variable instead of ?

The following worked for me -

var mysql = require('node-mysql');
var conn = mysql.createConnection({
    ...
});

var sql = "INSERT INTO Test (name, email, n) VALUES :params";
var values = [
    ['demian', '[email protected]', 1],
    ['john', '[email protected]', 2],
    ['mark', '[email protected]', 3],
    ['pete', '[email protected]', 4]
];
conn.query(sql, { params: values}, function(err) {
    if (err) throw err;
    conn.end();
});

Hope this helps someone.

Use SqlCommand.ExecuteScalar() and cast it to an int:

cmd.CommandText = "SELECT COUNT(*) FROM table_name";
Int32 count = (Int32) cmd.ExecuteScalar();

You can't use ^ and $ in character classes in the way you wish - they will be interpreted literally, but you can use an alternation to achieve the same effect:

(^|,)garp(,|$)

There is an actual Data Type called KeyValuePair, use like this

KeyValuePair<string, string> myKeyValuePair = new KeyValuePair<string,string>("defaultkey", "defaultvalue");

You can simply print it.

@a = qw(abc def hij);

print "@a";

You will got:

abc def hij

This example illustrate how to use AJAX to pull resourcess from any website. it works across browsers. i have tested it on IE8-IE10, safari, chrome, firefox, opera.

if (window.XDomainRequest) xmlhttp = new XDomainRequest();
else if (window.XMLHttpRequest) xmlhttp = new XMLHttpRequest();
else xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

xmlhttp.open("GET", "http://api.hostip.info/get_html.php", false);
xmlhttp.send();

hostipInfo = xmlhttp.responseText.split("\n");
var IP = false;
for (i = 0; hostipInfo.length >= i; i++) {
    if (hostipInfo[i]) {

        ipAddress = hostipInfo[i].split(":");
        if (ipAddress[0] == "IP") {
            IP = ipAddress[1];
        }
    }
}
return IP;

The pair RegOpenKey and RegQueryKeyEx will do the trick.

If you use MFC CRegKey class is even more easier solution.

I have added this function to a library I created vanillajs-browser-helpers: https://github.com/Tokimon/vanillajs-browser-helpers/blob/master/inView.js
-------------------------------

Well BenM stated, you need to detect the height of the viewport + the scroll position to match up with your top position. The function you are using is ok and does the job, though its a bit more complex than it needs to be.

If you don't use jQuery then the script would be something like this:

function posY(elm) {
    var test = elm, top = 0;

    while(!!test && test.tagName.toLowerCase() !== "body") {
        top += test.offsetTop;
        test = test.offsetParent;
    }

    return top;
}

function viewPortHeight() {
    var de = document.documentElement;

    if(!!window.innerWidth)
    { return window.innerHeight; }
    else if( de && !isNaN(de.clientHeight) )
    { return de.clientHeight; }
    
    return 0;
}

function scrollY() {
    if( window.pageYOffset ) { return window.pageYOffset; }
    return Math.max(document.documentElement.scrollTop, document.body.scrollTop);
}

function checkvisible( elm ) {
    var vpH = viewPortHeight(), // Viewport Height
        st = scrollY(), // Scroll Top
        y = posY(elm);
    
    return (y > (vpH + st));
}

Using jQuery is a lot easier:

function checkVisible( elm, evalType ) {
    evalType = evalType || "visible";

    var vpH = $(window).height(), // Viewport Height
        st = $(window).scrollTop(), // Scroll Top
        y = $(elm).offset().top,
        elementHeight = $(elm).height();

    if (evalType === "visible") return ((y < (vpH + st)) && (y > (st - elementHeight)));
    if (evalType === "above") return ((y < (vpH + st)));
}

This even offers a second parameter. With "visible" (or no second parameter) it strictly checks whether an element is on screen. If it is set to "above" it will return true when the element in question is on or above the screen.

See in action: http://jsfiddle.net/RJX5N/2/

I hope this answers your question.

-- IMPROVED VERSION--

This is a lot shorter and should do it as well:

function checkVisible(elm) {
  var rect = elm.getBoundingClientRect();
  var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
  return !(rect.bottom < 0 || rect.top - viewHeight >= 0);
}

with a fiddle to prove it: http://jsfiddle.net/t2L274ty/1/

And a version with threshold and mode included:

function checkVisible(elm, threshold, mode) {
  threshold = threshold || 0;
  mode = mode || 'visible';

  var rect = elm.getBoundingClientRect();
  var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
  var above = rect.bottom - threshold < 0;
  var below = rect.top - viewHeight + threshold >= 0;

  return mode === 'above' ? above : (mode === 'below' ? below : !above && !below);
}

and with a fiddle to prove it: http://jsfiddle.net/t2L274ty/2/

In my case, I had an input-group-btn with a button, and this button was a little bigger than its container. So I just gave font-size:95% for my glyphicon and it was solved.

<div class="input-group">
    <input type="text" class="form-control" id="pesquisarinbox" placeholder="Pesquisar na Caixa de Entrada">
    <div class="input-group-btn">
        <button class="btn btn-default" type="button">
            <span class="glyphicon glyphicon-search" style="font-size:95%;"></span>
        </button>
    </div>  
</div>

If you want to rotate a vector you should construct what is known as a rotation matrix.

Rotation in 2D

Say you want to rotate a vector or a point by ?, then trigonometry states that the new coordinates are

    x' = x cos ? - y sin ?
    y' = x sin ? + y cos ?

To demo this, let's take the cardinal axes X and Y; when we rotate the X-axis 90° counter-clockwise, we should end up with the X-axis transformed into Y-axis. Consider

    Unit vector along X axis = <1, 0>
    x' = 1 cos 90 - 0 sin 90 = 0
    y' = 1 sin 90 + 0 cos 90 = 1
    New coordinates of the vector, <x', y'> = <0, 1>  ?  Y-axis

When you understand this, creating a matrix to do this becomes simple. A matrix is just a mathematical tool to perform this in a comfortable, generalized manner so that various transformations like rotation, scale and translation (moving) can be combined and performed in a single step, using one common method. From linear algebra, to rotate a point or vector in 2D, the matrix to be built is

    |cos ?   -sin ?| |x| = |x cos ? - y sin ?| = |x'|
    |sin ?    cos ?| |y|   |x sin ? + y cos ?|   |y'|

Rotation in 3D

That works in 2D, while in 3D we need to take in to account the third axis. Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i.e. 0° (rotation happens on the XY plane in 3D). In 3D rotating around the Z-axis would be

    |cos ?   -sin ?   0| |x|   |x cos ? - y sin ?|   |x'|
    |sin ?    cos ?   0| |y| = |x sin ? + y cos ?| = |y'|
    |  0       0      1| |z|   |        z        |   |z'|

around the Y-axis would be

    | cos ?    0   sin ?| |x|   | x cos ? + z sin ?|   |x'|
    |   0      1       0| |y| = |         y        | = |y'|
    |-sin ?    0   cos ?| |z|   |-x sin ? + z cos ?|   |z'|

around the X-axis would be

    |1     0           0| |x|   |        x        |   |x'|
    |0   cos ?    -sin ?| |y| = |y cos ? - z sin ?| = |y'|
    |0   sin ?     cos ?| |z|   |y sin ? + z cos ?|   |z'|

Note 1: axis around which rotation is done has no sine or cosine elements in the matrix.

Note 2: This method of performing rotations follows the Euler angle rotation system, which is simple to teach and easy to grasp. This works perfectly fine for 2D and for simple 3D cases; but when rotation needs to be performed around all three axes at the same time then Euler angles may not be sufficient due to an inherent deficiency in this system which manifests itself as Gimbal lock. People resort to Quaternions in such situations, which is more advanced than this but doesn't suffer from Gimbal locks when used correctly.

I hope this clarifies basic rotation.

Rotation not Revolution

The aforementioned matrices rotate an object at a distance r = v(x² + y²) from the origin along a circle of radius r; lookup polar coordinates to know why. This rotation will be with respect to the world space origin a.k.a revolution. Usually we need to rotate an object around its own frame/pivot and not around the world's i.e. local origin. This can also be seen as a special case where r = 0. Since not all objects are at the world origin, simply rotating using these matrices will not give the desired result of rotating around the object's own frame. You'd first translate (move) the object to world origin (so that the object's origin would align with the world's, thereby making r = 0), perform the rotation with one (or more) of these matrices and then translate it back again to its previous location. The order in which the transforms are applied matters. Combining multiple transforms together is called concatenation or composition.

Composition

I urge you to read about linear and affine transformations and their composition to perform multiple transformations in one shot, before playing with transformations in code. Without understanding the basic maths behind it, debugging transformations would be a nightmare. I found this lecture video to be a very good resource. Another resource is this tutorial on transformations that aims to be intuitive and illustrates the ideas with animation (caveat: authored by me!).

Rotation around Arbitrary Vector

A product of the aforementioned matrices should be enough if you only need rotations around cardinal axes (X, Y or Z) like in the question posted. However, in many situations you might want to rotate around an arbitrary axis/vector. The Rodrigues' formula (a.k.a. axis-angle formula) is a commonly prescribed solution to this problem. However, resort to it only if you’re stuck with just vectors and matrices. If you're using Quaternions, just build a quaternion with the required vector and angle. Quaternions are a superior alternative for storing and manipulating 3D rotations; it's compact and fast e.g. concatenating two rotations in axis-angle representation is fairly expensive, moderate with matrices but cheap in quaternions. Usually all rotation manipulations are done with quaternions and as the last step converted to matrices when uploading to the rendering pipeline. See Understanding Quaternions for a decent primer on quaternions.

I was having similar issues connecting to OpenSUSE 13.1 MySQL database with LibreOffice. Update LibreOffice to latest stable "Still" package, then make sure the database is accessible using a tool such as phpMyAdmin. Make sure your user is linked to localhost and not "%" (any). This worked for me, I am able to add data thru LibreOffice.

Side note - LibreOffice Base will not supply "native connection" via MySQL on first attempt, you will need to use the back button, then try again to see the options.

Hope this helps.

Late to the party, but the tsbox package is designed to perform conversions like this. To convert your data into a ts-object, you can do:

dta <- data.frame(
  Dates = c("3/14/2013", "3/15/2013", "3/18/2013", "3/19/2013"),
  Bajaj_close = c(1854.8, 1850.3, 1812.1, 1835.9),
  Hero_close = c(1669.1, 1684.45, 1690.5, 1645.6)
)

dta
#>       Dates Bajaj_close Hero_close
#> 1 3/14/2013      1854.8    1669.10
#> 2 3/15/2013      1850.3    1684.45
#> 3 3/18/2013      1812.1    1690.50
#> 4 3/19/2013      1835.9    1645.60

library(tsbox)
ts_ts(ts_long(dta))
#> Time Series:
#> Start = 2013.1971293045 
#> End = 2013.21081883954 
#> Frequency = 365.2425 
#>          Bajaj_close Hero_close
#> 2013.197      1854.8    1669.10
#> 2013.200      1850.3    1684.45
#> 2013.203          NA         NA
#> 2013.205          NA         NA
#> 2013.208      1812.1    1690.50
#> 2013.211      1835.9    1645.60

It automatically parses the dates, detects the frequency and makes the missing values at the weekends explicit. With ts_<class>, you can convert the data to any other time series class.

There are different ways to return status code, 1 : RestController class should extends BaseRest class, in BaseRest class we can handle exception and return expected error codes. for example :

@RestController
@RequestMapping
class RestController extends BaseRest{

}

@ControllerAdvice
public class BaseRest {
@ExceptionHandler({Exception.class,...})
    @ResponseStatus(value=HttpStatus.INTERNAL_SERVER_ERROR)
    public ErrorModel genericError(HttpServletRequest request, 
            HttpServletResponse response, Exception exception) {
        
        ErrorModel error = new ErrorModel();
        resource.addError("error code", exception.getLocalizedMessage());
        return error;
    }
