The best answer I found on internet:

SELECT case when trim(TRANSLATE(col1, '0123456789-,.', ' ')) is null
            then 'numeric'
            else 'alpha'
       end
FROM tab1;

android:descendantFocusability="beforeDescendants"

using the following in the activity with some layout options below seemed to work as desired.

 getWindow().getDecorView().findViewById(android.R.id.content).clearFocus();

in connection with the following parameters on the root view.

<?xml
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:descendantFocusability="beforeDescendants" />

Answer thanks to: https://forums.xamarin.com/discussion/1856/how-to-disable-auto-focus-on-edit-text

About windowSoftInputMode

There's yet another point of contention to be aware of. By default, Android will automatically assign initial focus to the first EditText or focusable control in your Activity. It naturally follows that the InputMethod (typically the soft keyboard) will respond to the focus event by showing itself. The windowSoftInputMode attribute in AndroidManifest.xml, when set to stateAlwaysHidden, instructs the keyboard to ignore this automatically-assigned initial focus.

<activity
    android:name=".MyActivity"
    android:windowSoftInputMode="stateAlwaysHidden"/>

great reference

@CommonsWare explained all things quite well. And we really should use the solution he proposed.

By the way, only information we could rely on when querying ContentResolver is a file's name and size as mentioned here: Retrieving File Information | Android developers

As you could see there is an interface OpenableColumns that contains only two fields: DISPLAY_NAME and SIZE.

In my case I was need to retrieve EXIF information about a JPEG image and rotate it if needed before sending to a server. To do that I copied a file content into a temporary file using ContentResolver and openInputStream()

I think you called getActivity().startActivityForResult(intent,111);. You should call startActivityForResult(intent,111);.

Go to Reference and add a new reference of your dll file which is causing the problem and make sure that all your dlls are compiled against the same version. It works for me I hope it works for you also.

A1: Business Logic goes to Model part in MVC. Role of Model is to contain data and business logic. Controller on the other hand is responsible to receive user input and decide what to do.

A2: A Business Rule is part of Business Logic. They have a has a relationship. Business Logic has Business Rules.

Take a look at Wikipedia entry for MVC. Go to Overview where it mentions the flow of MVC pattern.

Also look at Wikipedia entry for Business Logic. It is mentioned that Business Logic is comprised of Business Rules and Workflow.

You don't need to set name , just giving an id is enough.

<input type="hidden" id="testId" />

and than with jquery you can use 'val()' method like below:

 $('#testId').val("work");

I used @jensgram solution to hide a div that contains a disabled input. So I hide the entire parent of the input.

Here is the code :

div:has(>input[disabled=disabled]) {
    display: none;
}

Maybe it could help some of you.

For example :

In MainActivity :

Intent intent = new Intent(this, OtherActivity.class);
intent.putExtra(OtherActivity.KEY_EXTRA, yourDataObject);
startActivity(intent);

In OtherActivity :

public static final String KEY_EXTRA = "com.example.yourapp.KEY_BOOK";

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  String yourDataObject = null;

  if (getIntent().hasExtra(KEY_EXTRA)) {
      yourDataObject = getIntent().getStringExtra(KEY_EXTRA);
  } else {
      throw new IllegalArgumentException("Activity cannot find  extras " + KEY_EXTRA);
  }
  // do stuff
}

You can use a split on a filename:

f_extns = filename.split(".")
print ("The extension of the file is : " + repr(f_extns[-1]))

This does not require additional library

Lot of good examples have been given. I'd like to add one:

Misapply them. You don't need to do that intentionally, it will happen when you try to apply them in your initial Design-Pattern-fit. During that time every single problem that you'll see will seem to fit exactly one design pattern. Often the problems all seem to fit the same design pattern for some reason (Singelton is a primary candidate for that).

And you'll apply the pattern and it will be good. And some months later you will need to change something in the code and see that using that particular pattern wasn't that smart, because you coded yourself into a corner and you need to refactor again.

Granted, that's not really a do-that-and-you'll-learn-it-in-21-days answer, but in my experience it's the most likely to give you a good insight into the matter.

$(document).ready(function(){

    $('.container').each(function(){  
        var highestBox = 0;

        $(this).find('.column').each(function(){
            if($(this).height() > highestBox){  
                highestBox = $(this).height();  
            }
        })

        $(this).find('.column').height(highestBox);
    });    


});

http://dev.mysql.com/doc/refman/5.0/en/case-sensitivity.html

The default character set and collation are latin1 and latin1_swedish_ci, so nonbinary string comparisons are case insensitive by default. This means that if you search with col_name LIKE 'a%', you get all column values that start with A or a. To make this search case sensitive, make sure that one of the operands has a case sensitive or binary collation. For example, if you are comparing a column and a string that both have the latin1 character set, you can use the COLLATE operator to cause either operand to have the latin1_general_cs or latin1_bin collation:

col_name COLLATE latin1_general_cs LIKE 'a%'
col_name LIKE 'a%' COLLATE latin1_general_cs
col_name COLLATE latin1_bin LIKE 'a%'
col_name LIKE 'a%' COLLATE latin1_bin

If you want a column always to be treated in case-sensitive fashion, declare it with a case sensitive or binary collation.

If you have a date object:

let date = new Date()_x000D_
let result = date.toISOString().split`T`[0]_x000D_
_x000D_
console.log(result)

or

let date = new Date()_x000D_
let result = date.toISOString().slice(0, 10)_x000D_
_x000D_
console.log(result)

Issue can be solved by adding CRT of msvcrtd.lib in the linker library. Because cryptlib.lib used CRT version of debug.

You could use background-size, as its supported by most browsers (but not all http://caniuse.com/#search=background-size)

background-size : 150% 150%;

Or

You can use a combo of zoom for webkit/ie and transform:scale for Firefox(-moz-) and Opera(-o-) for cross-browser desktop & mobile

[class^="icon-"]{
    display: inline-block;
    background: url('../img/icons/icons.png') no-repeat;
    width: 64px;
    height: 51px;
    overflow: hidden;
    zoom:0.5;
    -moz-transform:scale(0.5);
    -moz-transform-origin: 0 0;
}

.icon-huge{
    zoom:1;
    -moz-transform:scale(1);
    -moz-transform-origin: 0 0;
}

.icon-big{
    zoom:0.60;
    -moz-transform:scale(0.60);
    -moz-transform-origin: 0 0;
}

.icon-small{
    zoom:0.29;
    -moz-transform:scale(0.29);
    -moz-transform-origin: 0 0;

For anyone using Lodash, since v3.0.0 a _.escapeRegExp function is built-in:

_.escapeRegExp('[lodash](https://lodash.com/)');
// ? '\[lodash\]\(https:\/\/lodash\.com\/\)'

And, in the event that you don't want to require the full Lodash library, you may require just that function!

@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

You can negate an expression with "!":

#!/bin/bash
FILE=$1

if [ ! -f "$FILE" ]
then
    echo "File $FILE does not exist"
fi

The relevant man page is man test or, equivalently, man [ -- or help test or help [ for the built-in bash command.

why don't you use simple approach

    SELECT distinct *
    FROM 
    SUPPLIER full join 
    CUSTOMER on (
        CUSTOMER.OID = SUPPLIER.OID
    )

It gives you all columns from both tables and returns all records from customer and supplier if Customer has 3 records and supplier has 2 then supplier'll show NULL in all columns

I've installed Virutal PC according to Donavon's tutorial but it seems that my laptop's BIOS doesn't support Hardware Virtualization, and it's required to run Virtual PC. So, make sure your equipment supports that before you go any further wirh Virtual PC.

You can force IE10 to render in IE9 mode by adding:

<meta http-equiv="X-UA-Compatible" content="IE=9">

in your <head> tag.

After some limited testing with Spring 3.2, it seems one can use a SpEL list: {..., ..., ...}. This can also include null values. Spring passes the list as the key to the actual cache implementation. When using Ehcache, such will at some point invoke List#hashCode(), which takes all its items into account. (I am not sure if Ehcache only relies on the hash code.)

I use this for a shared cache, in which I include the method name in the key as well, which the Spring default key generator does not include. This way I can easily wipe the (single) cache, without (too much...) risking matching keys for different methods. Like:

@Cacheable(value="bookCache", 
  key="{ #root.methodName, #isbn?.id, #checkWarehouse }")
public Book findBook(ISBN isbn, boolean checkWarehouse) 
...

@Cacheable(value="bookCache", 
  key="{ #root.methodName, #asin, #checkWarehouse }")
public Book findBookByAmazonId(String asin, boolean checkWarehouse)
...

Of course, if many methods need this and you're always using all parameters for your key, then one can also define a custom key generator that includes the class and method name:

<cache:annotation-driven mode="..." key-generator="cacheKeyGenerator" />
<bean id="cacheKeyGenerator" class="net.example.cache.CacheKeyGenerator" />

...with:

public class CacheKeyGenerator 
  implements org.springframework.cache.interceptor.KeyGenerator {

    @Override
    public Object generate(final Object target, final Method method, 
      final Object... params) {

        final List<Object> key = new ArrayList<>();
        key.add(method.getDeclaringClass().getName());
        key.add(method.getName());

        for (final Object o : params) {
            key.add(o);
        }
        return key;
    }
}

Here is another way, by rotating element with the scrollbar for 180deg, wrapping it's content into another element, and rotating that wrapper for -180deg. Check the snippet below

div {_x000D_
  display: inline-block;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 2px solid black;_x000D_
  margin: 15px;_x000D_
}_x000D_
#vertical {_x000D_
  direction: rtl;_x000D_
  overflow-y: scroll;_x000D_
  overflow-x: hidden;_x000D_
  background: gold;_x000D_
}_x000D_
#vertical p {_x000D_
  direction: ltr;_x000D_
  margin-bottom: 0;_x000D_
}_x000D_
#horizontal {_x000D_
  direction: rtl;_x000D_
  transform: rotate(180deg);_x000D_
  overflow-y: hidden;_x000D_
  overflow-x: scroll;_x000D_
  background: tomato;_x000D_
  padding-top: 30px;_x000D_
}_x000D_
#horizontal span {_x000D_
  direction: ltr;_x000D_
  display: inline-block;_x000D_
  transform: rotate(-180deg);_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id=vertical>_x000D_
  <p>content_x000D_

Method 1:

With marquee tag.

HTML

<marquee behavior="scroll" bgcolor="yellow" loop="-1" width="30%">
   <i>
      <font color="blue">
        Today's date is : 
        <strong>
         <span id="time"></span>
        </strong>           
      </font>
   </i>
</marquee> 

JS

var today = new Date();
document.getElementById('time').innerHTML=today;

Fiddle demo here

Method 2:

Without marquee tag and with CSS.

HTML

<p class="marquee">
    <span id="dtText"></span>
</p>

CSS

.marquee {
   width: 350px;
   margin: 0 auto;
   background:yellow;
   white-space: nowrap;
   overflow: hidden;
   box-sizing: border-box;
   color:blue;
   font-size:18px;
}

.marquee span {
   display: inline-block;
   padding-left: 100%;
   text-indent: 0;
   animation: marquee 15s linear infinite;
}

.marquee span:hover {
    animation-play-state: paused
}

@keyframes marquee {
    0%   { transform: translate(0, 0); }
    100% { transform: translate(-100%, 0); }
}

JS

var today = new Date();
document.getElementById('dtText').innerHTML=today;

[[UIDevice currentDevice] uniqueIdentifier]

Returns the Unique ID of your iPhone.

EDIT: -[UIDevice uniqueIdentifier] is now deprecated and apps are being rejected from the App Store for using it. The method below is now the preferred approach.

If you need to create several UUID, just use this method (with ARC):

+ (NSString *)GetUUID
{
  CFUUIDRef theUUID = CFUUIDCreate(NULL);
  CFStringRef string = CFUUIDCreateString(NULL, theUUID);
  CFRelease(theUUID);
  return (__bridge NSString *)string;
}

EDIT: Jan, 29 2014: If you're targeting iOS 6 or later, you can now use the much simpler method:

NSString *UUID = [[NSUUID UUID] UUIDString];

DAYS360 does not calculate what you want, i.e. the number of days passed between the two dates. Use simple subtraction (-) or MINUS(). I made an updated copy of @DrCord’s sample spreadsheet to illustrate this.

Are you SURE you want DAYS360? That is a specialized function used in the financial sector to simplify calculations for bonds. It assumes a 360 day year, with 12 months of 30 days each. If you really want actual days, you'll lose 6 days each year. [source]

Try this regex:

/^[\w&.-]+$/

Also you can use test.

if ( pattern.test( qry ) ) {
  // valid
}

You can use extension method:

namespace extension
{
    public class ext
    {
        public static List<double> clone(this List<double> t)
        {
            List<double> kop = new List<double>();
            int x;
            for (x = 0; x < t.Count; x++)
            {
                kop.Add(t[x]);
            }
            return kop;
        }
   };

}

You can clone all objects by using their value type members for example, consider this class:

public class matrix
{
    public List<List<double>> mat;
    public int rows,cols;
    public matrix clone()
    { 
        // create new object
        matrix copy = new matrix();
        // firstly I can directly copy rows and cols because they are value types
        copy.rows = this.rows;  
        copy.cols = this.cols;
        // but now I can no t directly copy mat because it is not value type so
        int x;
        // I assume I have clone method for List<double>
        for(x=0;x<this.mat.count;x++)
        {
            copy.mat.Add(this.mat[x].clone());
        }
        // then mat is cloned
        return copy; // and copy of original is returned 
    }
};

Note: if you do any change on copy (or clone) it will not affect the original object.

If you are using jQuery 1.7:

alert($(this).prop("class"));

or:

alert($(event.target).prop("class"));

If you want to check if a string is empty:

if (str[0] == '\0')
{
    // your code here
}

If you have Java 6 (You should have, btw) or higher, then simply do this :

 Console console = System.console();
 String str = console.readLine("Please enter the xxxx : ");

Please remember to do :

 import java.io.Console;

Thats it!

scp -r C:/site user@server_ip:path

path is the place, where site will be copied into the remote server

EDIT: As I said in my comment, try pscp, as you want to use scp using PuTTY.

The other option is WinSCP

Start with Firebug and IE Debugger.

Be careful with debuggers in JavaScript though. Every once in a while they will affect the environment just enough to cause some of the errors you are trying to debug.

Examples:

For Internet Explorer, it's generally a gradual slowdown and is some kind of memory leak type deal. After a half hour or so I need to restart. It seems to be fairly regular.

For Firebug, it's probably been more than a year so it may have been an older version. As a result, I don't remember the specifics, but basically the code was not running correctly and after trying to debug it for a while I disabled Firebug and the code worked fine.

socket.gethostname() could do

if result is None:
    print "error parsing stream"
elif result:
    print "result pass"
else:
    print "result fail"

keep it simple and explicit. You can of course pre-define a dictionary.

messages = {None: 'error', True: 'pass', False: 'fail'}
print messages[result]

If you plan on modifying your simulate function to include more return codes, maintaining this code might become a bit of an issue.

The simulate might also raise an exception on the parsing error, in which case you'd either would catch it here or let it propagate a level up and the printing bit would be reduced to a one-line if-else statement.

I came across the same problem and found that somehow the file 'applicationhost.config' (in ..\Documents\IISExpress\config) had a different localhost port number (in the 'sites' section) to the one specified in project\properties\web. Changed them to the same number and the problem went away

I'm not sure if you want to find duplicate files or just compare two single files. If the latter, the above approach (filecmp) is better, if the former, the following approach is better.

There are lots of duplicate files detection questions here. Assuming they are not very small and that performance is important, you can

• Compare file sizes first, discarding all which doesn't match
• If file sizes match, compare using the biggest hash you can handle, hashing chunks of files to avoid reading the whole big file

Here's is an answer with Python implementations (I prefer the one by nosklo, BTW)

To find distinct in field_1 in collection but we want some WHERE condition too than we can do like following :

db.your_collection_name.distinct('field_1', {WHERE condition here and it should return a document})

So, find number distinct names from a collection where age > 25 will be like :

db.your_collection_name.distinct('names', {'age': {"$gt": 25}})

Hope it helps!

An array is a structure with a certain size. You can use dynamic arrays in vba that you can shrink or grow using ReDim but you can't remove elements in the middle. It's not clear from your sample how your array functionally works or how you determine the index position (eachHdr) but you basically have 3 options

(A) Write a custom 'delete' function for your array like (untested)

Public Sub DeleteElementAt(Byval index As Integer, Byref prLst as Variant)
       Dim i As Integer

        ' Move all element back one position
        For i = index + 1 To UBound(prLst)
            prLst(i - 1) = prLst(i)
        Next

        ' Shrink the array by one, removing the last one
        ReDim Preserve prLst(Len(prLst) - 1)
End Sub

(B) Simply set a 'dummy' value as the value instead of actually deleting the element

If prLst(eachHdr) = "0" Then        
   prLst(eachHdr) = "n/a"
End If

(C) Stop using an array and change it into a VBA.Collection. A collection is a (unique)key/value pair structure where you can freely add or delete elements from

Dim prLst As New Collection

In Bootstrap 4, there is a new utility known as .mx-auto. You just need to specify the width of the centered element.

Ref: http://v4-alpha.getbootstrap.com/utilities/spacing/#horizontal-centering

Diffferent from Bass Jobsen's answer, which is a relative center to the elements on both ends, the following example is absolute centered.

And CSS:

.navbar-logo {
  width: 90px;
}

Personally i'm against using culture specific code, i suggest doing:

@String.Format(CultureInfo.CurrentCulture, "{0:C}", @price)

and in your web.config do:

<system.web>
    <globalization culture="en-GB" uiCulture="en-US" />
</system.web>

@Pradip Kharbuja

In Cordova-2.6.0.js (l. 4032) :

exitApp:function() {
  console.log("Device.exitApp() is deprecated. Use App.exitApp().");
  app.exitApp();
}

Applying

    <item name="android:statusBarColor">@color/color_primary_dark</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>

in Theme.AppCompat.Light.DarkActionBar didn't worked for me. What did the trick is , giving colorPrimaryDark as usual along with android:colorPrimary in styles.xml

<item name="android:colorAccent">@color/color_primary</item>
<item name="android:colorPrimary">@color/color_primary</item>
<item name="android:colorPrimaryDark">@color/color_primary_dark</item>

and in setting

if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop)
                {
                    Window window = this.Window;
                    Window.AddFlags(WindowManagerFlags.DrawsSystemBarBackgrounds);
                }

didn't had to set statusbar color in code .

From String to Date

String dtStart = "2010-10-15T09:27:37Z";  
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");  
try {  
    Date date = format.parse(dtStart);  
    System.out.println(date);  
} catch (ParseException e) {
    e.printStackTrace();  
}

From Date to String

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");  
try {  
    Date date = new Date();  
    String dateTime = dateFormat.format(date);
    System.out.println("Current Date Time : " + dateTime); 
} catch (ParseException e) {
    e.printStackTrace();  
}

You probably have a list containing one unicode string. The repr of this is [u'String'].

You can convert this to a list of byte strings using any variation of the following:

# Functional style.
print map(lambda x: x.encode('ascii'), my_list)

# List comprehension.
print [x.encode('ascii') for x in my_list]

# Interesting if my_list may be a tuple or a string.
print type(my_list)(x.encode('ascii') for x in my_list)

# What do I care about the brackets anyway?
print ', '.join(repr(x.encode('ascii')) for x in my_list)

# That's actually not a good way of doing it.
print ' '.join(repr(x).lstrip('u')[1:-1] for x in my_list)

Handy oneliner:

$csv = array_map('str_getcsv', file('data.csv'));

1. Add float:left; property in both divs.

2. Add display:inline-block; property.

3. Add display:flex; property in parent div.

If you want to build Java EE applications, it's best to use Eclipse IDE for Java EE. It has editors from HTML to JSP/JSF, Javascript. It's rich for webapps development, and provide plugins and tools to develop Java EE applications easily (all bundled).

Eclipse Classic is basically the full featured Eclipse without the Java EE part.

This will get your buttons and labels next to each other, at least. I believe the second part can't be done in css alone, and will need javascript. I found a page that might help you with that part as well, but I don't have time right now to try it out: http://www.webmasterworld.com/forum83/6942.htm

<style type="text/css">
.input input {
  float: left;
}
.input label {
  margin: 5px;
}
</style>
<div class="input radio">
    <fieldset>
        <legend>What color is the sky?</legend>
        <input type="hidden" name="data[Submit][question]" value="" id="SubmitQuestion" />

        <input type="radio" name="data[Submit][question]" id="SubmitQuestion1" value="1"  />
        <label for="SubmitQuestion1">A strange radient green.</label>

        <input type="radio" name="data[Submit][question]" id="SubmitQuestion2" value="2"  />
        <label for="SubmitQuestion2">A dark gloomy orange</label>
        <input type="radio" name="data[Submit][question]" id="SubmitQuestion3" value="3"  />
        <label for="SubmitQuestion3">A perfect glittering blue</label>
    </fieldset>
</div>

I had a similar issue with Pandas, you need to use the iterrows() function to iterate through a Pandas dataset Pandas documentation for iterrows

data = pd.read_csv('foo.csv')
for index,item in data.iterrows():
    print('{} {}'.format(item["gravatar_id"], item["position"]))

note that you need to handle the index in the dataset that is also returned by the function.

Create a function to move it:

function move_file($file, $to){
    $path_parts = pathinfo($file);
    $newplace   = "$to/{$path_parts['basename']}";
    if(rename($file, $newplace))
        return $newplace;
    return null;
}

     String s = "having Community Portal|Help Desk|Local Embassy|Reference Desk|Site News";
     StringTokenizer st = new StringTokenizer(s, "|");
        String community = st.nextToken();
        String helpDesk = st.nextToken(); 
        String localEmbassy = st.nextToken();
        String referenceDesk = st.nextToken();
        String siteNews = st.nextToken();

Not at all an ideal solution, I just wanted to add this for future reference for anyone seeing this page:

I was having this issue trying to connect to a remote SQL Server instance using my domain account, trying the same thing on an instance hosted on a different machine worked fine.

So if you have the option to just use a different instance it may help, but this doesn't actually address whatever the issue is.

position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
margin: auto;

Apparently, the SSH server on Raspbian is now disabled by default. If there is no server listening for connections, it will not accept them. You can manually enable the SSH server according to this raspberrypi.org tutorial :

As of the November 2016 release, Raspbian has the SSH server disabled by default.

There are now multiple ways to enable it. Choose one:

From the desktop

1. Launch Raspberry Pi Configuration from the Preferences menu
2. Navigate to the Interfaces tab
3. Select Enabled next to SSH
4. Click OK

From the terminal with raspi-config

1. Enter sudo raspi-config in a terminal window
2. Select Interfacing Options
3. Navigate to and select SSH
4. Choose Yes
5. Select Ok
6. Choose Finish

Start the SSH service with systemctl

sudo systemctl enable ssh
sudo systemctl start ssh

On a headless Raspberry Pi

For headless setup, SSH can be enabled by placing a file named ssh, without any extension, onto the boot partition of the SD card. When the Pi boots, it looks for the ssh file. If it is found, SSH is enabled, and the file is deleted. The content of the file does not matter: it could contain text, or nothing at all.

Bottom line, the easiest way to append to a tuple is to enclose the element being added with parentheses and a comma.

t = ('a', 4, 'string')
t = t + (5.0,)
print(t)

out: ('a', 4, 'string', 5.0)

Step-by-step:

• let's say you are working on a project use-gulp which uses(requires) node_modules like gulp and gulp-util.
• Now you want to make some modifications to gulp-util lib and test it locally with your use-gulp project...
• Fork gulp-util project on github\bitbucket etc.
• Switch to your project: cd use-gulp/node_modules
• Clone gulp-util as gulp-util-dev : git clone https://.../gulp-util.git gulp-util-dev
• Run npm install to ensure dependencies of gulp-util-dev are available.
• Now you have a mirror of gulp-util as gulp-util-dev. In your use-gulp project, you can now replace: require('gulp-util')...; call with : require('gulp-util-dev') to test your changes you made to gulp-util-dev

If you receive "MMMM" as a response, probably you are getting the month and then converting it to a string of defined format.

DateTime.Now.Month.ToString("MMMM") 

will output "MMMM"

DateTime.Now.ToString("MMMM") 

will output the month name

Place this in the ~/.m2/settings.xml or custom file to be run with $ mvn -s custom-settings.xml install

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0

And for yet another option, I'd go with awk!

echo "foo bar <foo> bla 1 2 3.4" | awk '{ print $(NF-1), $NF; }'

This will split the input (I'm using STDIN here, but your input could easily be a file) on spaces, and then print out the last-but-one field, and then the last field. The $NF variables hold the number of fields found after exploding on spaces.

The benefit of this is that it doesn't matter if what precedes the last two fields changes, as long as you only ever want the last two it'll continue to work.

If class has only one empty constructor (like Activity or Fragment etc, android classes):

Class<?> myClass = Class.forName("com.example.MyClass");    
Constructor<?> constructor = myClass.getConstructors()[0];

1. Don't use quotation in a field name or table name inside the query.

2. After fetching an object you need to access object attributes/properties (in your case id) by attributes/properties name.

One note: please use mysqli_* or PDO since mysql_* deprecated. Here it is using mysqli:

session_start();
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = new mysqli('localhost', 'username', 'password', 'db_name');
$link->set_charset('utf8mb4'); // always set the charset
$name = $_GET["username"];
$stmt = $link->prepare("SELECT id FROM Users WHERE username=? limit 1");
$stmt->bind_param('s', $name);
$stmt->execute();
$result = $stmt->get_result();
$value = $result->fetch_object();
$_SESSION['myid'] = $value->id;

Bonus tips: Use limit 1 for this type of scenario, it will save execution time :)

Here's my little class that can reprint blocks of text. It properly clears the previous text so you can overwrite your old text with shorter new text without creating a mess.

import re, sys

class Reprinter:
    def __init__(self):
        self.text = ''

    def moveup(self, lines):
        for _ in range(lines):
            sys.stdout.write("\x1b[A")

    def reprint(self, text):
        # Clear previous text by overwritig non-spaces with spaces
        self.moveup(self.text.count("\n"))
        sys.stdout.write(re.sub(r"[^\s]", " ", self.text))

        # Print new text
        lines = min(self.text.count("\n"), text.count("\n"))
        self.moveup(lines)
        sys.stdout.write(text)
        self.text = text

reprinter = Reprinter()

reprinter.reprint("Foobar\nBazbar")
reprinter.reprint("Foo\nbar")

All you need to do for that is a simple loop.
This doesn't handle testing for lower case, upper-case mismatch. If this isn't exactly what you are looking for, comment, and I can revise.

If you are planning to learn VBA. This is a great start.

TESTED:

Sub MatchAndColor()

Dim lastRow As Long
Dim sheetName As String

    sheetName = "Sheet1"            'Insert your sheet name here
    lastRow = Sheets(sheetName).Range("A" & Rows.Count).End(xlUp).Row

    For lRow = 2 To lastRow         'Loop through all rows

        If Sheets(sheetName).Cells(lRow, "A") = Sheets(sheetName).Cells(lRow, "B") Then
            Sheets(sheetName).Cells(lRow, "A").Interior.ColorIndex = 3  'Set Color to RED
        End If

    Next lRow

End Sub

For anyone else who wants to set Eclipse style goto definition, you need to create .sublime-mousemap file in Sublime User folder.

Windows - create Default (Windows).sublime-mousemap in %appdata%\Sublime Text 3\Packages\User

Linux - create Default (Linux).sublime-mousemap in ~/.config/sublime-text-3/Packages/User

Mac - create Default (OSX).sublime-mousemap in ~/Library/Application Support/Sublime Text 3/Packages/User

Now open that file and put the following configuration inside

[
    {
        "button": "button1", 
        "count": 1, 
        "modifiers": ["ctrl"],
        "press_command": "drag_select",
        "command": "goto_definition"
    }
]

You can change modifiers key as you like.

Since Ctrl-button1 on Windows and Linux is used for multiple selections, adding a second modifier key like Alt might be a good idea if you want to use both features:

[
    {
        "button": "button1", 
        "count": 1, 
        "modifiers": ["ctrl", "alt"],
        "press_command": "drag_select",
        "command": "goto_definition"
    }
]

Alternatively, you could use the right mouse button (button2) with Ctrl alone, and not interfere with any built-in functions.

It depends on your file path. For me, the current directory was [project]\bin\Debug, so I had to move to the parent folder twice.

Image image = Image.FromFile(@"..\..\Pictures\"+text+".png");
this.pictureBox1.Image = image;

To find your current directory, you can make a dummy label called label2 and write this:

this.label2.Text = System.IO.Directory.GetCurrentDirectory();

If you dont want the outline for button with all the status, you can override the css with below code

.btn.active.focus, .btn.active:focus, 
.btn.focus, .btn:active.focus, 
.btn:active:focus, .btn:focus{
  outline: none;
}

Go to the page from where you want to access the App_code class, and then add the namespace of the app_code class. You need to provide a using statement, as follows:

using WebApplication3.App_Code;

After that, you will need to go to the app_code class property and set the 'Build Action' to 'Compile'.

You've mentioned that they each have their own machines, but if they need to log onto a co-workers machine, and then use the file, saving it through "C:\Users\Public\Desktop\" will make it available to different usernames.

Public Sub SaveToDesktop()
    ThisWorkbook.SaveAs Filename:="C:\Users\Public\Desktop\" & ThisWorkbook.Name & "_copy", _ 
    FileFormat:=xlOpenXMLWorkbookMacroEnabled
End Sub

I'm not sure whether this would be a requirement, but may help!

Have a max int and set it to the first value in the array. Then in a for loop iterate through the whole array and see if the max int is larger than the int at the current index.

int max = array.get(0);

for (int i = 1; i < array.length; i++) {
    if (array.get(i) > max) {
      max = array.get(i);
    }
}

use spawn

import os
os.spawnlp(os.P_WAIT, 'cp', 'cp', 'index.html', '/dev/null')

Instead of using

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

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

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

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

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

You didn't create your project as "Dynamic Web Project", so Eclipse doesn't recognize it like a web project. Create a new "Dynamic Web Project" or go to Properties ? Projects Facets and check Dynamic Web Module.

Built a tiny, confirm-like vanilla js yes / no dialog.
https://www.npmjs.com/package/yesno-dialog

Ruby unfortunately is a bit different. PS: My memory is a bit hazy on this so apologies if I'm wrong

instead of break/continue, it has break/next, which behave the same in terms of loops

Loops (like everything else) are expressions, and "return" the last thing that they did. Most of the time, getting the return value from a loop is pointless, so everyone just does this

a = 5
while a < 10
    a + 1
end

You can however do this

a = 5
b = while a < 10
    a + 1
end # b is now 10

HOWEVER, a lot of ruby code 'emulates' a loop by using a block. The canonical example is

10.times do |x|
    puts x
end

As it is much more common for people to want to do things with the result of a block, this is where it gets messy. break/next mean different things in the context of a block.

break will jump out of the code that called the block

next will skip the rest of the code in the block, and 'return' what you specify to the caller of the block. This doesn't make any sense without examples.

def timesten
    10.times{ |t| puts yield t }
end


timesten do |x|
   x * 2
end
# will print
2
4
6
8 ... and so on


timesten do |x|
    break
    x * 2
end
# won't print anything. The break jumps out of the timesten function entirely, and the call to `puts` inside it gets skipped

timesten do |x|
    break 5
    x * 2
end
# This is the same as above. it's "returning" 5, but nobody is catching it. If you did a = timesten... then a would get assigned to 5

timesten do |x|
    next 5
    x * 2
end 
# this would print
5
5
5 ... and so on, because 'next 5' skips the 'x * 2' and 'returns' 5.

So yeah. Ruby is awesome, but it has some awful corner-cases. This is the second worst one I've seen in my years of using it :-)

npm install will install all the packages from npm-shrinkwrap.json, but might ignore packages in package.json, if they're not preset in the former.

If you're project has a npm-shrinkwrap.json, make sure you run npm shrinkwrap to regenerate it, each time you add add/remove/change package.json.

Simple solution:

Hit this Simple command in project Folder(it won't remove your original changes) ...it will only remove changes that had been done while you changed project folder permission

command is below:

git config core.fileMode false

Why this all unnecessary file get modified: because you have changed the project folder permissions with commend sudo chmod -R 777 ./yourProjectFolder

when will you check changes what not you did? you found like below while using git diff filename

old mode 100644
new mode 100755

in api 26 with build.gradle 3.0.0 and higher you can create a font directory in res and use this line in your style

<item name="android:fontFamily">@font/your_font</item>

for change build.gradle use this in your build.gradle dependecies

classpath 'com.android.tools.build:gradle:3.0.0'

I just want to add an alternative solution for the problem by using only Java code. No extra library

public String Capitalize(String str) {

            String tt = "";
            String tempString = "";
            String tempName = str.trim().toLowerCase();
            String[] tempNameArr = tempName.split(" ");
            System.out.println("The size is " + tempNameArr.length);
            if (tempNameArr.length > 1) {
                for (String t : tempNameArr) {
                    tt += Capitalize(t);
                    tt += " ";
                }
                tempString  = tt;
            } else {
                tempString = tempName.replaceFirst(String.valueOf(tempName.charAt(0)), String.valueOf(tempName.charAt(0)).toUpperCase());
            }
            return tempString.trim();
        }

std::vector<CustomClass *> whatever(20000);

or:

std::vector<CustomClass *> whatever;
whatever.reserve(20000);

The former sets the actual size of the array -- i.e., makes it a vector of 20000 pointers. The latter leaves the vector empty, but reserves space for 20000 pointers, so you can insert (up to) that many without it having to reallocate.

At least in my experience, it's fairly unusual for either of these to make a huge difference in performance--but either can affect correctness under some circumstances. In particular, as long as no reallocation takes place, iterators into the vector are guaranteed to remain valid, and once you've set the size/reserved space, you're guaranteed there won't be any reallocations as long as you don't increase the size beyond that.

I just came across the same issue while trying to query a MySQL Database from Pentaho.

Error connecting to database [Local MySQL DB] : org.pentaho.di.core.exception.KettleDatabaseException: Error occured while trying to connect to the database

Exception while loading class org.gjt.mm.mysql.Driver

Expanding post by @user979331 the solution is:

1. Download the MySQL Java Connector / Driver that is compatible with your kettle version
2. Unzip the zip file (in my case it was mysql-connector-java-5.1.31.zip)

3. copy the .jar file (mysql-connector-java-5.1.31-bin.jar) and paste it in your Lib folder:

   PC: C:\Program Files\pentaho\design-tools\data-integration\lib

   Mac: /Applications/data-integration/lib

Restart Pentaho (Data Integration) and re-test the MySQL Connection.

Additional interesting replies from others that could also help:

• think to download the good JDBC driver version, compatible with your PDI version: https://help.pentaho.com/Documentation/8.1/Setup/JDBC_Drivers_Reference#MY_SQL
• take the zip version ("platform independant") to extract the jar file
• take into lib folder
• see also proper way to handle it proposed by Ryan Tuck

Here is a one liner that does this, just replace username with the username you want to kill things for. Don't even think on putting root there!

pkill -9 -u `id -u username`

Note: if you want to be nice remove -9, but it will not kill all kinds of processes.

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

File object docs (for Python 2) here.

select T.TABLE_NAME, T.TABLESPACE_NAME, t.avg_row_len*t.num_rows from dba_tables t
order by T.TABLE_NAME asc

See e.g. http://www.dba-oracle.com/t_script_oracle_table_size.htm for more options

This will work fast:

Case 1 - File2 = File1 + extra text appended.

grep -Fxvf File2.txt File1.txt >> File3.txt

File 1: 80 Lines File 2: 100 Lines File 3: 20 Lines

if you are using windows os and believe that skype is not the suspect, then you might want to check the task manager and check the "Show processes from all users" and make sure that there is NO entry for httpd.exe. Otherwise, end its process. That solves my problem.

This can be achieved through LINQ with grouping, here a list of items pointed as a data source to the actual grid view. Sample pseudo code which could help coding the actual.

var tabelDetails =(from li in dc.My_table
    join m in dc.Table_One on li.ID equals m.ID
    join c in dc.Table_two on li.OtherID equals c.ID
    where //Condition
group new { m, li, c } by new
{
    m.ID,
    m.Name
} into g
select new
{
    g.Key.ID,
    Name = g.Key.FullName,
    sponsorBonus= g.Where(s => s.c.Name == "sponsorBonus").Count(),
    pairingBonus = g.Where(s => s.c.Name == "pairingBonus").Count(),
    staticBonus = g.Where(s => s.c.Name == "staticBonus").Count(),   
    leftBonus = g.Where(s => s.c.Name == "leftBonus").Count(),  
    rightBonus = g.Where(s => s.c.Name == "rightBonus").Count(),  
    Total = g.Count()  //Row wise Total
}).OrderBy(t => t.Name).ToList();

tabelDetails.Insert(tabelDetails.Count(), new  //This data will be the last row of the grid
{
    Name = "Total",  //Column wise total
    sponsorBonus = tabelDetails.Sum(s => s.sponsorBonus),
    pairingBonus = tabelDetails.Sum(s => s.pairingBonus),
    staticBonus = tabelDetails.Sum(s => s.staticBonus),
    leftBonus = tabelDetails.Sum(s => s.leftBonus),
    rightBonus = tabelDetails.Sum(s => s.rightBonus ),
    Total = tabelDetails.Sum(s => s.Total)
});

You should be able to simply do this:

Context context = new InitialContext();
dataSource = (javax.sql.DataSource) context.lookup("jdbc/myDataSource");

If you are looking it up from a remote destination you need to use the WL initial context factory like this:

Hashtable<String, String> h = new Hashtable<String, String>(7);
h.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
h.put(Context.PROVIDER_URL, pURL); //For example "t3://127.0.0.1:7001"
h.put(Context.SECURITY_PRINCIPAL, pUsername);
h.put(Context.SECURITY_CREDENTIALS, pPassword);

InitialContext context = new InitialContext(h);
dataSource = (javax.sql.DataSource) context.lookup("jdbc/myDataSource");

weblogic.jndi.WLInitialContextFactory

If you want to set through xml using android's default color codes, then you need to do as below:

android:background="@android:color/white"

If you have colors specified in your project's colors.xml, then use:

android:background="@color/white"

If you want to do programmatically, then do:

linearlayout.setBackgroundColor(Color.WHITE);

Try:

$('li.current_sub').prevAll("li.par_cat:first");

Tested it with your markup:

$('li.current_sub').prevAll("li.par_cat:first").text("woohoo");

will fill up the closest previous li.par_cat with "woohoo".

SQL Server Express doesn't include SQL Server Agent, so it's not possible to just create SQL Agent jobs.

What you can do is:
You can create jobs "manually" by creating batch files and SQL script files, and running them via Windows Task Scheduler.
For example, you can backup your database with two files like this:

backup.bat:

sqlcmd -i backup.sql

backup.sql:

backup database TeamCity to disk = 'c:\backups\MyBackup.bak'

Just put both files into the same folder and exeute the batch file via Windows Task Scheduler.

The first file is just a Windows batch file which calls the sqlcmd utility and passes a SQL script file.
The SQL script file contains T-SQL. In my example, it's just one line to backup a database, but you can put any T-SQL inside. For example, you could do some UPDATE queries instead.

If the jobs you want to create are for backups, index maintenance or integrity checks, you could also use the excellent Maintenance Solution by Ola Hallengren.

It consists of a bunch of stored procedures (and SQL Agent jobs for non-Express editions of SQL Server), and in the FAQ there’s a section about how to run the jobs on SQL Server Express:

How do I get started with the SQL Server Maintenance Solution on SQL Server Express?

SQL Server Express has no SQL Server Agent. Therefore, the execution of the stored procedures must be scheduled by using cmd files and Windows Scheduled Tasks. Follow these steps.

SQL Server Express has no SQL Server Agent. Therefore, the execution of the stored procedures must be scheduled by using cmd files and Windows Scheduled Tasks. Follow these steps.

1. Download MaintenanceSolution.sql.

2. Execute MaintenanceSolution.sql. This script creates the stored procedures that you need.

3. Create cmd files to execute the stored procedures; for example:
   sqlcmd -E -S .\SQLEXPRESS -d master -Q "EXECUTE dbo.DatabaseBackup @Databases = 'USER_DATABASES', @Directory = N'C:\Backup', @BackupType = 'FULL'" -b -o C:\Log\DatabaseBackup.txt

4. In Windows Scheduled Tasks, create tasks to call the cmd files.

5. Schedule the tasks.

6. Start the tasks and verify that they are completing successfully.

If you simply want to initialise a member field or property with the constructor parameter, in C# >= 3 you can do it very easier:

public static string GetAllItems<T>(...) where T : InterfaceOrBaseClass, new() 
{ 
   ... 
   List<T> tabListItems = new List<T>(); 
   foreach (ListItem listItem in listCollection)  
   { 
       tabListItems.Add(new T{ BaseMemberItem = listItem }); // No error, BaseMemberItem owns to InterfaceOrBaseClass. 
   }  
   ... 
} 

This is the same thing Garry Shutler said, but I'd like to put an aditional note.

Of course you can use a property trick to do more stuff than just setting a field value. A property "set()" can trigger any processing needed to setup its related fields and any other need for the object itself, including a check to see if a full initialization is to take place before the object is used, simulating a full contruction (yes, it is an ugly workaround, but it overcomes M$'s new() limitation).

I can't be assure if it is a planned hole or an accidental side effect, but it works.

It is very funny how MS people adds new features to the language and seems to not do a full side effects analysis. The entire generic thing is a good evidence of this...

You can use the get_group method:

In [21]: gb.get_group('foo')
Out[21]: 
     A         B   C
0  foo  1.624345   5
2  foo -0.528172  11
4  foo  0.865408  14

Note: This doesn't require creating an intermediary dictionary / copy of every subdataframe for every group, so will be much more memory-efficient than creating the naive dictionary with dict(iter(gb)). This is because it uses data-structures already available in the groupby object.

You can select different columns using the groupby slicing:

In [22]: gb[["A", "B"]].get_group("foo")
Out[22]:
     A         B
0  foo  1.624345
2  foo -0.528172
4  foo  0.865408

In [23]: gb["C"].get_group("foo")
Out[23]:
0     5
2    11
4    14
Name: C, dtype: int64

You can't directly, enum in C++ are not like Java enums.

The usual approach is to create a std::map<WeekEnum,std::string>.

std::map<WeekEnum,std::string> m;
m[Mon] = "Monday";
//...
m[Sun] = "Sunday";

Almost 2 years later....
This github project readme has a some clarity of configuration of the maven plugin and it seems, according to this apache github project, the plugin itself will materialise soon enough.

Just revisiting this, I've made it a little bit tidier (though someone who is full bottle on Prototype/JavaScript could suggest improvements?).

var TextAreaResize = Class.create();
TextAreaResize.prototype = {
  initialize: function(element, options) {
    element = $(element);
    this.element = element;

    this.options = Object.extend(
      {},
      options || {});

    Event.observe(this.element, 'keyup',
      this.onKeyUp.bindAsEventListener(this));
    this.onKeyUp();
  },

  onKeyUp: function() {
    // We need this variable because "this" changes in the scope of the
    // function below.
    var cols = this.element.cols;

    var linecount = 0;
    $A(this.element.value.split("\n")).each(function(l) {
      // We take long lines into account via the cols divide.
      linecount += 1 + Math.floor(l.length / cols);
    })

    this.element.rows = linecount;
  }
}

Just it call with:

new TextAreaResize('textarea_id_name_here');

Solution using Decorators that survives minification/uglification

We use code generation to decorate our Entity classes with metadata like so:

@name('Customer')
export class Customer {
  public custId: string;
  public name: string;
}

Then consume with the following helper:

export const nameKey = Symbol('name');

/**
 * To perserve class name though mangling.
 * @example
 * @name('Customer')
 * class Customer {}
 * @param className
 */
export function name(className: string): ClassDecorator {
  return (Reflect as any).metadata(nameKey, className);
}

/**
 * @example
 * const type = Customer;
 * getName(type); // 'Customer'
 * @param type
 */
export function getName(type: Function): string {
  return (Reflect as any).getMetadata(nameKey, type);
}

/**
 * @example
 * const instance = new Customer();
 * getInstanceName(instance); // 'Customer'
 * @param instance
 */
export function getInstanceName(instance: Object): string {
  return (Reflect as any).getMetadata(nameKey, instance.constructor);
}

Extra info:

• You may need to install reflect-metadata
• reflect-metadata is pollyfill written by members ot TypeScript for the proposed ES7 Reflection API
• The proposal for decorators in JS can be tracked here

Google has released a new API to deal with onBackPressed in Fragment:

activity?.onBackPressedDispatcher?.addCallback(viewLifecycleOwner, object : OnBackPressedCallback(true) {
            override fun handleOnBackPressed() {

            }
        })

If CURLOPT_FAILONERROR is false, http errors will not trigger curl errors.

<?php
if (@$_GET['curl']=="yes") {
  header('HTTP/1.1 503 Service Temporarily Unavailable');
} else {
  $ch=curl_init($url = "http://".$_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF']."?curl=yes");
  curl_setopt($ch, CURLOPT_FAILONERROR, true);
  $response=curl_exec($ch);
  $http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  $curl_errno= curl_errno($ch);
  if ($http_status==503)
    echo "HTTP Status == 503 <br/>";
  echo "Curl Errno returned $curl_errno <br/>";
}

I have got a answer for Hibernate Query Language to use Distinct fields. You can use *SELECT DISTINCT(TO_CITY) FROM FLIGHT_ROUTE*. If you use SQL query, it return String List. You can't use it return value by Entity Class. So the Answer to solve that type of Problem is use HQL with SQL.

FROM FLIGHT_ROUTE F WHERE F.ROUTE_ID IN (SELECT SF.ROUTE_ID FROM FLIGHT_ROUTE SF GROUP BY SF.TO_CITY);

From SQL query statement it got DISTINCT ROUTE_ID and input as a List. And IN query filter the distinct TO_CITY from IN (List).

Return type is Entity Bean type. So you can it in AJAX such as AutoComplement.

May all be OK

Swift 5: Here is a cool and easy extension to remove elements in an array, without filtering :

   extension Array where Element: Equatable {

    // Remove first collection element that is equal to the given `object`:
    mutating func remove(object: Element) {
        guard let index = firstIndex(of: object) else {return}
        remove(at: index)
    }

}

Usage :

var myArray = ["cat", "barbecue", "pancake", "frog"]
let objectToRemove = "cat"

myArray.remove(object: objectToRemove) // ["barbecue", "pancake", "frog"]

Also works with other types, such as Int since Element is a generic type:

var myArray = [4, 8, 17, 6, 2]
let objectToRemove = 17

myArray.remove(object: objectToRemove) // [4, 8, 6, 2]

If you are looking inside dockerfile while creating image, add this line:

RUN apk add --update yourPackageName

You could do this using SUMIF. This allows you to SUM a value in a cell IF a value in another cell meets the specified criteria. Here's an example:

 -   A         B
 1   100       YES
 2   100       YES
 3   100       NO

Using the formula: =SUMIF(B1:B3, "YES", A1:A3), you will get the result of 200.

Here's a screenshot of a working example I just did in Excel:

You can use form-inline class for each form-group :)

<form>                      
    <div class="form-group form-inline">                            
        <label for="exampleInputEmail1">Email address</label>
            <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Email">
    </div>
</form>

You don't need to escape the ' character in a String (wrapped in "), and you don't have to escape a " character in a char (wrapped in ').

you can use overflow property to the container div if you don't have any div to show over the container eg:

<div class="cointainer">
    <div class="one">Content One</div>
    <div class="two">Content Two</div>
</div>

Here is the following css:

.container{
    width:100%;/* As per your requirment */
    height:auto;
    float:left;
    overflow:hidden;
}
.one{
    width:200px;/* As per your requirment */
    height:auto;
    float:left;
}

.two{
    width:200px;/* As per your requirment */
    height:auto;
    float:left;
}

-----------------------OR------------------------------

    <div class="cointainer">
        <div class="one">Content One</div>
        <div class="two">Content Two</div>
        <div class="clearfix"></div>
    </div>

Here is the following css:

    .container{
        width:100%;/* As per your requirment */
        height:auto;
        float:left;
        overflow:hidden;
    }
    .one{
        width:200px;/* As per your requirment */
        height:auto;
        float:left;
    }

    .two{
        width:200px;/* As per your requirment */
        height:auto;
        float:left;
    }
    .clearfix:before,
    .clearfix:after{
        display: table;
        content: " ";
    }
    .clearfix:after{
        clear: both;
    }

As other have stated, you can use microtime() to get millisecond precision on timestamps.

From your comments, you seem to want it as a high-precision UNIX Timestamp. Something like DateTime.Now.Ticks in the .NET world.

You may use the following function to do so:

function millitime() {
  $microtime = microtime();
  $comps = explode(' ', $microtime);

  // Note: Using a string here to prevent loss of precision
  // in case of "overflow" (PHP converts it to a double)
  return sprintf('%d%03d', $comps[1], $comps[0] * 1000);
}

If you want to change Status Bar Style from the launch screen, You should take this way.

1. Go to Project -> Target,

2. Set Status Bar Style to Light

3. Set View controller-based status bar appearance to NO in Info.plist.

Here is what made the error disappear for me:

Close eclipse, open up a terminal window and run:

$ mvn clean eclipse:clean eclipse:eclipse

Are you using Maven? If so,

1. Right-click on the project, Build Path and go to Configure Build Path
2. Click the libraries tab. If Maven dependencies are not in the list, you need to add it.
3. Close the dialog.

To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.

And then clean

Edit 1:

If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.

Edit 2:

You can also try going into the folder where you have all your projects and delete the .metadata for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.

<h2>Image Modal</h2>
<p>In this example, we use CSS to create a modal (dialog box) that is hidden by default.</p>
<p>We use JavaScript to trigger the modal and to display the current image inside the modal when it is clicked on. Also note that we use the value from the image's "alt" attribute as an image caption text inside the modal.</p>

<img id="myImg" src="img_snow.jpg" alt="Snow" style="width:100%;max-width:300px">

<!-- The Modal -->
<div id="myModal" class="modal">
  <span class="close">&times;</span>
  <img class="modal-content" id="img01">
  <div id="caption"></div>
</div>

<script>
// Get the modal
var modal = document.getElementById("myModal");

// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById("myImg");
var modalImg = document.getElementById("img01");

Here is an alternate solution for version 4.x of Select2. You can use listeners to catch the focus event and then open the select.

$('#test').select2({
    // Initialisation here
}).data('select2').listeners['*'].push(function(name, target) { 
    if(name == 'focus') {
        $(this.$element).select2("open");
    }
});

I have just completed a android App about wsdl,i have some tips to append:

1.the most important resource is www.wsdl2code.com

2.you can take you username and password with header, which encoded with Base64,such as :

        String USERNAME = "yourUsername";
    String PASSWORD = "yourPassWord";
    StringBuffer auth = new StringBuffer(USERNAME);
    auth.append(':').append(PASSWORD);
    byte[] raw = auth.toString().getBytes();
    auth.setLength(0);
    auth.append("Basic ");
    org.kobjects.base64.Base64.encode(raw, 0, raw.length, auth);
    List<HeaderProperty> headers = new ArrayList<HeaderProperty>();
    headers.add(new HeaderProperty("Authorization", auth.toString())); // "Basic V1M6"));

    Vectordianzhan response = bydWs.getDianzhans(headers);

3.somethimes,you are not sure either ANDROID code or webserver is wrong, then debug is important.in the sample , catching "XmlPullParserException" ,log "requestDump" and "responseDump"in the exception.additionally, you should catch the IP package with adb.

    try {
    Logg.i(TAG, "2  ");
    Object response = androidHttpTransport.call(SOAP_ACTION, envelope, headers); 
    Logg.i(TAG, "requestDump: " + androidHttpTransport.requestDump);
    Logg.i(TAG, "responseDump: "+ androidHttpTransport.responseDump);
    Logg.i(TAG, "3");
} catch (IOException e) {
    Logg.i(TAG, "IOException");
} 
catch (XmlPullParserException e) {
     Logg.i(TAG, "requestDump: " + androidHttpTransport.requestDump);
     Logg.i(TAG, "responseDump: "+ androidHttpTransport.responseDump);
     Logg.i(TAG, "XmlPullParserException");
     e.printStackTrace();
}

Your __init__.py should have a docstring.

Although all the functionality is implemented in modules and subpackages, your package docstring is the place to document where to start. For example, consider the python email package. The package documentation is an introduction describing the purpose, background, and how the various components within the package work together. If you automatically generate documentation from docstrings using sphinx or another package, the package docstring is exactly the right place to describe such an introduction.

For any other content, see the excellent answers by firecrow and Alex Martelli.

Starting with .NET Core 2.1 there is a new way to reverse a string using the string.Create method.

Note that this solution does not handle Unicode combining characters etc. correctly, as "Les Mise\u0301rables" would be converted to "selbarésiM seL". The the other answers for a better solution.

public static string Reverse(string input)
{
    return string.Create<string>(input.Length, input, (chars, state) =>
    {
        state.AsSpan().CopyTo(chars);
        chars.Reverse();
    });
}

This essentially copies the characters of input to a new string and reverses the new string in-place.

Why is string.Create useful?

When we create a string from an existing array, a new internal array is allocated and the values are copied. Otherwise, it would be possible to mutate a string after its creation (in a safe environment). That is, in the following snippet we have to allocate an array of length 10 twice, one as the buffer and one as the string's internal array.

var chars = new char[10];
// set array values
var str = new string(chars);

string.Create essentially allows us to manipulate the internal array during creation time of the string. This is, we do not need a buffer anymore and can therefore avoid allocating that one char array.

Steve Gordon has written about it in more detail here. There is also an article on MSDN.

How to use string.Create?

public static string Create<TState>(int length, TState state, SpanAction<char, TState> action);

The method takes three parameters:

1. The length of the string to create,
2. the data you want to use to dynamically create the new string,
3. and a delegate that creates the final string from the data, where the first parameter points to the internal char array of the new string and the second is the data (state) you passed to string.Create.

Inside the delegate we can specify how the new string is created from the data. In our case, we just copy the characters of the input string to the Span used by the new string. Then we reverse the Span and hence the whole string is reversed.

Benchmarks

To compare my proposed way of reversing a string with the accepted answer, I have written two benchmarks using BenchmarkDotNet.

public class StringExtensions
{
    public static string ReverseWithArray(string input)
    {
        var charArray = input.ToCharArray();
        Array.Reverse(charArray);
        return new string(charArray);
    }

    public static string ReverseWithStringCreate(string input)
    {
        return string.Create(input.Length, input, (chars, state) =>
        {
            state.AsSpan().CopyTo(chars);
            chars.Reverse();
        });
    }
}

[MemoryDiagnoser]
public class StringReverseBenchmarks
{
    private string input;

    [Params(10, 100, 1000)]
    public int InputLength { get; set; }


    [GlobalSetup]
    public void SetInput()
    {
        // Creates a random string of the given length
        this.input = RandomStringGenerator.GetString(InputLength);
    }

    [Benchmark(Baseline = true)]
    public string WithReverseArray() => StringExtensions.ReverseWithArray(input);

    [Benchmark]
    public string WithStringCreate() => StringExtensions.ReverseWithStringCreate(input);
}

Here are the results on my machine:

As you can see, with ReverseWithStringCreate we allocate only half of the memory used by the ReverseWithArray method.

You could try in this way.

SOAPMessage msg = messageContext.getMessage();
ByteArrayOutputStream out = new ByteArrayOutputStream();
msg.writeTo(out);
String strMsg = new String(out.toByteArray());

This is from exercise 3.28 from the book Introduction to Java Programming- Comprehensive Edition. The code tests whether the two rectangles are indenticle, whether one is inside the other and whether one is outside the other. If none of these condition are met then the two overlap.

**3.28 (Geometry: two rectangles) Write a program that prompts the user to enter the center x-, y-coordinates, width, and height of two rectangles and determines whether the second rectangle is inside the first or overlaps with the first, as shown in Figure 3.9. Test your program to cover all cases. Here are the sample runs:

Enter r1's center x-, y-coordinates, width, and height: 2.5 4 2.5 43 Enter r2's center x-, y-coordinates, width, and height: 1.5 5 0.5 3 r2 is inside r1

Enter r1's center x-, y-coordinates, width, and height: 1 2 3 5.5 Enter r2's center x-, y-coordinates, width, and height: 3 4 4.5 5 r2 overlaps r1

Enter r1's center x-, y-coordinates, width, and height: 1 2 3 3 Enter r2's center x-, y-coordinates, width, and height: 40 45 3 2 r2 does not overlap r1

import java.util.Scanner;

    Scanner input = new Scanner(System.in);

    System.out
            .print("Enter r1's center x-, y-coordinates, width, and height:");
    double x1 = input.nextDouble();
    double y1 = input.nextDouble();
    double w1 = input.nextDouble();
    double h1 = input.nextDouble();
    w1 = w1 / 2;
    h1 = h1 / 2;
    System.out

A cool trick is to use "1p to paste the last delete/change (, and then use . to repeatedly to paste the subsequent deletes. In other words, "1p... is basically equivalent to "1p"2p"3p"4p.

You can use this to reverse-order a handful of lines: dddddddddd"1p....

I would would wrap the <ul> with a <div ng-cloak>

You might not have the ability to install Expect on the target server. This is often the case when one writes, say, a Jenkins job.

If so, I would consider something like the answer to the following on askubuntu.com:

https://askubuntu.com/questions/338857/automatically-enter-input-in-command-line

printf 'y\nyes\nno\nmaybe\n' | ./script_that_needs_user_input

Note that in some rare cases the command does not require the user to press enter after the character. in that case leave the newlines out:

printf 'yyy' | ./script_that_needs_user_input

For sake of completeness you can also use a here document:

./script_that_needs_user_input << EOF
y
y
y
EOF

Or if your shell supports it a here string:

./script <<< "y
y
y
"

Or you can create a file with one input per line:

./script < inputfile

Again, all credit for this answer goes to the author of the answer on askubuntu.com, lesmana.

Add .* to s in your first line.

Try:

DELETE s.* FROM spawnlist s
INNER JOIN npc n ON s.npc_templateid = n.idTemplate
WHERE (n.type = "monster");

Please, modern is easier, and faster. On Linux, (pick one)

truncate -s 10G foo
fallocate -l 5G bar

It needs to be stated that truncate on a file system supporting sparse files will create a sparse file and fallocate will not. A sparse file is one where the allocation units that make up the file are not actually allocated until used. The meta-data for the file will however take up some considerable space but likely no where near the actual size of the file. You should consult resources about sparse files for more information as there are advantages and disadvantages to this type of file. A non-sparse file has its blocks (allocation units) allocated ahead of time which means the space is reserved as far as the file system sees it. Also fallocate nor truncate will not set the contents of the file to a specified value like dd, instead the contents of a file allocated with fallocate or truncate may be any trash value that existed in the allocated units during creation and this behavior may or may not be desired. The dd is the slowest because it actually writes the value or chunk of data to the entire file stream as specified with it's command line options.

This behavior could potentially be different - depending on file system used and conformance of that file system to any standard or specification. Therefore it is advised that proper research is done to ensure that the appropriate method is used.

Catch the base exception 'Exception'

   try { 
         //some code
   } catch (Exception e) {
        //catches exception and all subclasses 
   }

In short, they are exactly the same. If you notice the end of the URL, sometimes you'll see .htm and other times you'll see .html. It still refers to the Hyper-Text Markup Language.

If you want to access both the key and value, use the following:

Python 2:

for key, value in my_dict.iteritems():
    print(key, value)

Python 3:

for key, value in my_dict.items():
    print(key, value)

Thanks to https://stackoverflow.com/users/1652962/cimmanon that gave me the answer.

The solution is setting a height to the vertical scrollable element. For example:

#container article {
    flex: 1 1 auto;
    overflow-y: auto;
    height: 0px;
}

The element will have height because flexbox recalculates it unless you want a min-height so you can use height: 100px; that it is exactly the same as: min-height: 100px;

#container article {
    flex: 1 1 auto;
    overflow-y: auto;
    height: 100px; /* == min-height: 100px*/
}

So the best solution if you want a min-height in the vertical scroll:

#container article {
    flex: 1 1 auto;
    overflow-y: auto;
    min-height: 100px;
}

If you just want full vertical scroll in case there is no enough space to see the article:

#container article {
    flex: 1 1 auto;
    overflow-y: auto;
    min-height: 0px;
}

The final code: http://jsfiddle.net/ch7n6/867/

With your private key and public certificate, you need to create a PKCS12 keystore first, then convert it into a JKS.

# Create PKCS12 keystore from private key and public certificate.
openssl pkcs12 -export -name myservercert -in selfsigned.crt -inkey server.key -out keystore.p12

# Convert PKCS12 keystore into a JKS keystore
keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert

To verify the contents of the JKS, you can use this command:

keytool -list -v -keystore mykeystore.jks

If this was not a self-signed certificate, you would probably want to follow this step with importing the certificate chain leading up to the trusted CA cert.

As far as I know, display: inline-block is what you probably need. That will make it seem like it's sort of inline but still allow you to use things like margins and such.

Practice safe computing. Simply go up one level in the hierarchy and don't use a wildcard expression:

cd ..; rm -rf -- <dir-to-remove>

The two dashes -- tell rm that <dir-to-remove> is not a command-line option, even when it begins with a dash.

when you use postfix it instantiates on more object in memory. Some people say that it is better to use suffix operator in for loop

Using NewRequest just to create an URL is an overkill. Use the net/url package:

package main

import (
    "fmt"
    "net/url"
)

func main() {
    base, err := url.Parse("http://www.example.com")
    if err != nil {
        return
    }

    // Path params
    base.Path += "this will get automatically encoded"

    // Query params
    params := url.Values{}
    params.Add("q", "this will get encoded as well")
    base.RawQuery = params.Encode() 

    fmt.Printf("Encoded URL is %q\n", base.String())
}

Playground: https://play.golang.org/p/YCTvdluws-r

class expression can be used for simplicity.

 // Foo.js
'use strict';

// export default class Foo {}
module.exports = class Foo {}

-

// main.js
'use strict';

const Foo = require('./Foo.js');

let Bar = new class extends Foo {
  constructor() {
    super();
    this.name = 'bar';
  }
}

console.log(Bar.name);

For folks searching for solution to set spacing between N divs, here is another approach using pseudo selectors:

div:not(:last-child) {
  margin-right: 40px;
}

You can also combine child pseudo selectors:

div:not(:first-child):not(:last-child) {
  margin-left: 20px;
  margin-right: 20px;
}

1. From the Home screen, press the Menu key.
2. List item
3. Touch Settings.
4. Touch Applications.
5. Touch Manage Applications.
6. Touch All.
7. Select the application that is having issues.
8. Touch Clear data and Clear cache if they are available. This resets the app as if it was new, and may delete personal data stored in the app.

You can try this:

df['2nd'] = pd.to_numeric(df['2nd'].str.replace(',', ''))
df['CTR'] = pd.to_numeric(df['CTR'].str.replace('%', ''))

The problem with iframes not getting 100% height is not because they're unwieldy. The problem is that for them to get 100% height they need their parents to have 100% height. If one of the iframe's parents is not 100% tall the iframe won't be able to go beyond that parent's height.

So the best possible solution would be:

html, body, iframe { height: 100%; }

…given the iframe is directly under body. If the iframe has a parent between itself and the body, the iframe will still get the height of its parent. One must explicitly set the height of every parent to 100% as well (if that's what one wants).

Tested in:

Chrome 30, Firefox 24, Safari 6.0.5, Opera 16, IE 7, 8, 9 and 10

PS: I don't mean to be picky but the solution marked as correct doesn't work on Firefox 24 at the time of this writing, but worked on Chrome 30. Haven't tested on other browsers though. I came across the error on Firefox because the page I was testing had very little content... It could be it's my meager markup or the CSS reset altering the output, but if I experienced this error I guess the accepted answer doesn't work in every situation.

Update 2021

@Zeni suggested this in 2015:

iframe { height: 100vh }

...and indeed it does the trick!

Careful with positioning as it can potentially break the effect. Test thoroughly, you might not need positioning depending of what you're trying to achieve.

The highest voted answer (MishieMoo) is correct but it doesn't explain how to open Podfile.lock. Everytime I tried I kept getting:

You open it in terminal by going to the folder it's in and running:

vim Podfile.lock

I got the answer from here: how to open Podfile.lock

You close it by pressing the colon and typing quit or by pressing the colon and the letter q then enter

:quit // then return key
:q // then return key

Another way is in terminal, you can also cd to the folder that your Xcode project is in and enter

$ open Podfile.lock -a Xcode

Doing it the second way, after it opens just press the red X button in the upper left hand corner to close.

This is a little C program that illustrates how you could use color codes:

#include <stdio.h>

#define KNRM  "\x1B[0m"
#define KRED  "\x1B[31m"
#define KGRN  "\x1B[32m"
#define KYEL  "\x1B[33m"
#define KBLU  "\x1B[34m"
#define KMAG  "\x1B[35m"
#define KCYN  "\x1B[36m"
#define KWHT  "\x1B[37m"

int main()
{
    printf("%sred\n", KRED);
    printf("%sgreen\n", KGRN);
    printf("%syellow\n", KYEL);
    printf("%sblue\n", KBLU);
    printf("%smagenta\n", KMAG);
    printf("%scyan\n", KCYN);
    printf("%swhite\n", KWHT);
    printf("%snormal\n", KNRM);

    return 0;
}

You can use the following code snippet :

java -XX:+PrintFlagsFinal -Xms512m -Xmx1024m -Xss512k -XX:PermSize=64m -XX:MaxPermSize=128m
    -version | grep -iE 'HeapSize|PermSize|ThreadStackSize'

In my pc I am getting following output :

    uintx InitialHeapSize                          := 536870912       {product}
    uintx MaxHeapSize                              := 1073741824      {product}
    uintx PermSize                                 := 67108864        {pd product}
    uintx MaxPermSize                              := 134217728       {pd product}
     intx ThreadStackSize                          := 512             {pd product}

Well, you are having a valid access token to access your information and not others( this is because you got logged in and you have given permission to access your information). But the picture owner has not done the same (logged in + permission ) and so you are getting a violation error.

To obtain permission see this link and decide what kind of informations you want from any user and decide the permissions. Later on embed this in your code. (In the login function call)

Thanks

You can use this;

String.format("%1$s %2$s %2$s %3$s", "a", "b", "c");

Output:

a b b c

The inverse, as the name says, but sometimes "close enough" is "close enough"; an interesting read anyway.

I would suggest the use of exists instead of in because in some scenarios that implies null values the behavior is different, so

CREATE TRIGGER sampleTrigger
    ON database1.dbo.table1
    FOR DELETE
AS
    DELETE FROM database2.dbo.table2 childTable
    WHERE bar = 4 AND exists (SELECT id FROM deleted where deleted.id = childTable.id)
GO

Jupyter is base on ipython, a permanent solution could be changing the ipython config options.

Create a config file

$ ipython profile create
$ ipython locate
/Users/username/.ipython

Edit the config file

$ cd /Users/username/.ipython
$ vi profile_default/ipython_config.py

The following lines allow you to add your module path to sys.path

c.InteractiveShellApp.exec_lines = [
    'import sys; sys.path.append("/path/to/your/module")'
]

At the jupyter startup the previous line will be executed

Here you can find more details about ipython config https://www.lucypark.kr/blog/2013/02/10/when-python-imports-and-ipython-does-not/

after reading StackOverflow answers the simple solution I got is

.profilePosts div {

background: url("xyz");
background-size: contain;
background-repeat: no-repeat;
width: x;
height: y;

}

I think it is better to copy files from your local computer, because if files number or file size is very big, copying process could be interrupted if your current ssh session would be lost (broken pipe or whatever).

If you have configured ssh key to connect to your remote server, you could use the following command:

rsync -avP -e "ssh -i /home/local_user/ssh/key_to_access_remote_server.pem" remote_user@remote_host.ip:/home/remote_user/file.gz /home/local_user/Downloads/

Where v option is --verbose, a option is --archive - archive mode, P option same as --partial - keep partially transferred files, e option is --rsh=COMMAND - specifying the remote shell to use.

rsync man page

As mentioned previously you really can't do this. You can do a modal dialog inside the window using a UI framework, or you can have a popup window, with a script that auto-closes after a timeout... each has a negative aspect. The modal window inside the browser won't create any notification if the window is minimized, and a programmatic (timer based) popup is likely to be blocked by modern browsers, and popup blockers.

Try below code if you want to use php loop to display

<span>
  <select name="birth_month">
    <?php for( $m=1; $m<=12; ++$m ) { 
      $month_label = date('F', mktime(0, 0, 0, $m, 1));
    ?>
      <option value="<?php echo $month_label; ?>"><?php echo $month_label; ?></option>
    <?php } ?>
  </select> 
</span>
<span>
  <select name="birth_day">
    <?php 
      $start_date = 1;
      $end_date   = 31;
      for( $j=$start_date; $j<=$end_date; $j++ ) {
        echo '<option value='.$j.'>'.$j.'</option>';
      }
    ?>
  </select>
</span>
<span>
  <select name="birth_year">
    <?php 
      $year = date('Y');
      $min = $year - 60;
      $max = $year;
      for( $i=$max; $i>=$min; $i-- ) {
        echo '<option value='.$i.'>'.$i.'</option>';
      }
    ?>
  </select>
</span>

if you want to split the plot into two columns (2 plots next to each other), you can do it like this:

par(mfrow=c(1,2))

plot(x)

plot(y)

The REST camp have some guiding principles that we can use to standardize the way we use HTTP verbs. This is helpful when building RESTful API's as you are doing.

In a nutshell: GET should be Read Only i.e. have no effect on server state. POST is used to create a resource on the server. PUT is used to update or create a resource. DELETE is used to delete a resource.

In other words, if your API action changes the server state, REST advises us to use POST/PUT/DELETE, but not GET.

User agents usually understand that doing multiple POSTs is bad and will warn against it, because the intent of POST is to alter server state (eg. pay for goods at checkout), and you probably don't want to do that twice!

Compare to a GET which you can do an often as you like (idempotent).

I had issue with the solutions mentioned above as specifying the string key would give me javax.el.PropertyNotFoundException. The code shown below worked for me. In this I used status to count the index of for each loop and displayed the value of index I am interested on

<c:forEach items="${requestScope.key}"  var="map" varStatus="status" >
    <c:if test="${status.index eq 1}">
        <option><c:out value=${map.value}/></option>
    </c:if>

I favor the dplyr approach.

group_by(id) followed by either

• filter(row_number()==1) or
• slice(1) or
• slice_head(1) #(dplyr => 1.0)
• top_n(n = -1)
  • top_n() internally uses the rank function. Negative selects from the bottom of rank.

In some instances arranging the ids after the group_by can be necessary.

library(dplyr)

# using filter(), top_n() or slice()

m1 <-
test %>% 
  group_by(id) %>% 
  filter(row_number()==1)

m2 <-
test %>% 
  group_by(id) %>% 
  slice(1)

m3 <-
test %>% 
  group_by(id) %>% 
  top_n(n = -1)

All three methods return the same result

# A tibble: 5 x 2
# Groups:   id [5]
     id string
  <int> <fct> 
1     1 A     
2     2 B     
3     3 C     
4     4 D     
5     5 E

array_push — Push one or more elements onto the end of array

Take note of the words "one or more elements onto the end" to do that using $arr[] you would have to get the max size of the array

Create a HttpRequestMessage, set the Method to GET, set your headers and then use SendAsync instead of GetAsync.

var client = new HttpClient();
var request = new HttpRequestMessage() {
    RequestUri = new Uri("http://www.someURI.com"),
    Method = HttpMethod.Get,
};
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("text/plain"));
var task = client.SendAsync(request)
    .ContinueWith((taskwithmsg) =>
    {
        var response = taskwithmsg.Result;

        var jsonTask = response.Content.ReadAsAsync<JsonObject>();
        jsonTask.Wait();
        var jsonObject = jsonTask.Result;
    });
task.Wait();

I have Notepad++ v6.8.8

Find: [([a-zA-Z])]

Replace: [\'\1\']

Will produce: $array[XYZ] => $array['XYZ']

This works for me, in MVC5:

@Html.TextBoxFor(m => m.Name, new { @class = "form-control", id = "theID" , @Value="test" })

One of the most used tool in the scientific community to that purpose is DummyNet. Once you have installed the ipfw kernel module, in order to introduce 50ms propagation delay between 2 machines simply run these commands:

./ipfw pipe 1 config delay 50ms
./ipfw add 1000 pipe 1 ip from $IP_MACHINE_1 to $IP_MACHINE_2

In order to also introduce 50% of packet losses you have to run:

./ipfw pipe 1 config plr 0.5

GIMP tool is exactly what you need to create the images for different pixel resolution devices.

Follow these steps:

1. Open the existing image in GIMP tool.
2. Go to "Image" menu, and select "Scale Image..."

3. Use below pixel dimension that you need:

   xxxhdpi: 1280x1920 px

   xxhdpi: 960x1600 px

   xhdpi: 640x960 px

   hdpi: 480x800 px

   mdpi: 320x480 px

   ldpi: 240x320 px

4. Then "Export" the image from "File" menu.

You can wrap the inputs in col-* classes

<form name="registration_form" id="registration_form" class="form-horizontal">
     <div class="form-group">
           <div class="col-sm-6">
             <label for="firstname" class="sr-only"></label>
             <input id="firstname" class="form-control input-group-lg reg_name" type="text" name="firstname" title="Enter first name" placeholder="First name">
           </div>       
           <div class="col-sm-6">
             <label for="lastname" class="sr-only"></label>
             <input id="lastname" class="form-control input-group-lg reg_name" type="text" name="lastname" title="Enter last name" placeholder="Last name">
           </div>
    </div><!--/form-group-->

    <div class="form-group">
        <div class="col-sm-12">
          <label for="username" class="sr-only"></label>
          <input id="username" class="form-control input-group-lg" type="text" autocapitalize="off" name="username" title="Enter username" placeholder="Username">
        </div>
    </div><!--/form-group-->

    <div class="form-group">
        <div class="col-sm-12">
        <label for="password" class="sr-only"></label>
        <input id="password" class="form-control input-group-lg" type="password" name="password" title="Enter password" placeholder="Password">

You should do something like this:

1) create directory object what would point to server-side accessible folder

CREATE DIRECTORY image_files AS '/data/images'
/

2) Place your file into OS folder directory object points to

3) Give required access privileges to Oracle schema what will load data from file into table:

GRANT READ ON DIRECTORY image_files TO scott
/

4) Use BFILENAME, EMPTY_BLOB functions and DBMS_LOB package (example NOT tested - be care) like in below:

DECLARE
  l_blob BLOB; 
  v_src_loc  BFILE := BFILENAME('IMAGE_FILES', 'myimage.png');
  v_amount   INTEGER;
BEGIN
  INSERT INTO esignatures  
  VALUES (100, 'BOB', empty_blob()) RETURN iblob INTO l_blob; 
  DBMS_LOB.OPEN(v_src_loc, DBMS_LOB.LOB_READONLY);
  v_amount := DBMS_LOB.GETLENGTH(v_src_loc);
  DBMS_LOB.LOADFROMFILE(l_blob, v_src_loc, v_amount);
  DBMS_LOB.CLOSE(v_src_loc);
  COMMIT;
END;
/

After this you get the content of your file in BLOB column and can get it back using Java for example.

edit: One letter left missing: it should be LOADFROMFILE.

„line 23. Is this div right? or must this be a section?“

Neither – there is a main tag for that purpose, which is only allowed once per page and should be used as a wrapper for the main content (in contrast to a sidebar or a site-wide header).

<main>
    <!-- The main content -->
</main>

http://www.w3.org/html/wg/drafts/html/master/grouping-content.html#the-main-element

You can set TextBox properties for setting negative number display and decimal places settings.

1. Right-click the cell and then click Text Box Properties.
2. Select Number, and in the Category field, click Currency.

$("#display").load("?control=msgs", {}, function() { 
  $('#header').focus();
});

i tried it but it doesn't work, please give me more advice to resolve this problem. thanks for your help

This command will apply the patch not resolving it leaving bad files as *.rej:

git apply --reject --whitespace=fix mypath.patch

You just have to resolve them. Once resolved run:

git -am resolved

An unwanted single quote was my problem. Checking the connection string from the location of the index mentioned in the error string helped me spot the issue.

I was facing the same issue as below.

npm ERR! errno -4058 npm ERR! syscall open npm ERR! enoent ENOENT: no such file or directory, open 'D:\SVenu\FullStackDevelopment\Angular\Angular2_Splitter_CodeSkeleton\CodeSke leton\run\package.json' npm ERR! enoent This is related to npm not being able to find a file. npm ERR! enoent

The problem I made was, I was running the command npm build run instead of running npm run build.

Just sharing to help someone who does small mistakes like me.

$_FILES["file"]["name"] - the name of the uploaded file

from http://www.w3schools.com/php/php_file_upload.asp

I would just create a separate CSS class:

.ButtonClicked {
    background-color:red;
}

And then add the class on click:

$('#ButtonId').on('click',function(){
    !$(this).hasClass('ButtonClicked') ? addClass('ButtonClicked') : '';
});

This should do what you're looking for, showing by this jsFiddle. If you're curious about the logic with the ? and such, its called ternary (or conditional) operators, and its just a concise way to do the simple if logic to check if the class has already been added.

You can also create the ability to have an "on/off" switch feel by toggling the class:

$('#ButtonId').on('click',function(){
    $(this).toggleClass('ButtonClicked');
});

Shown by this jsFiddle. Just food for thought.

Handle SIGPIPE Locally

It's usually best to handle the error locally rather than in a global signal event handler since locally you will have more context as to what's going on and what recourse to take.

I have a communication layer in one of my apps that allows my app to communicate with an external accessory. When a write error occurs I throw and exception in the communication layer and let it bubble up to a try catch block to handle it there.

Code:

The code to ignore a SIGPIPE signal so that you can handle it locally is:

// We expect write failures to occur but we want to handle them where 
// the error occurs rather than in a SIGPIPE handler.
signal(SIGPIPE, SIG_IGN);

This code will prevent the SIGPIPE signal from being raised, but you will get a read / write error when trying to use the socket, so you will need to check for that.

what is the type of the field EventDate, since the ordering isn't correct i assume you don't have it set to some Date/Time representing type, but a string. And then the american way of writing dates is nasty to sort

Yes, It is possible. I've separated the code in two files:

index.php

<?php

    $time = time()+(60*60*24*10);
    $timeMemo = (string)$time;
    setcookie("cookie", "" . $timeMemo . "", $time);

?>
<html>
    <head>
        <title>
            Get cookie expiration date from JS
        </title>
        <script type="text/javascript">

            function cookieExpirationDate(){

                var infodiv = document.getElementById("info");

                var xmlhttp;
                if (window.XMLHttpRequest){ 
                    xmlhttp = new XMLHttpRequest;
                }else{
                    xmlhttp = new ActiveXObject(Microsoft.XMLHTTP);
                }

                xmlhttp.onreadystatechange = function (){
                    if(xmlhttp.readyState == 4 && xmlhttp.status == 200){
                        infodiv.innerHTML = xmlhttp.responseText;
                    }
                }

                xmlhttp.open("GET", "cookie.php", true);
                xmlhttp.send();

            }

        </script>
    </head>
    <body>
        <input type="button" onclick="javascript:cookieExpirationDate();" value="Get Cookie expire date" />
        <hr />
        <div id="info">
        </div>
    </body>
</html>

cookie.php

<?php

    function secToDays($sec){
        return ($sec / 60 / 60 / 24);
    }

    if(isset($_COOKIE['cookie'])){

        if(round(secToDays((intval($_COOKIE['cookie']) - time())),1) < 1){
            echo "Cookie will expire today";
        }else{
            echo "Cookie will expire in " . round(secToDays((intval($_COOKIE['cookie']) - time())),1) . " day(s)";
        }
    }else{
        echo "Cookie not set...";
    }

?>

Now, index.php must be loaded once. The button "Get Cookie expire date", thru an AJAX request, will always get you an updated "time left" for cookie expiration, in this case in days.

I found very nice solution. Microsoft released a beta version of Entity Framework Power Tools: Entity Framework Power Tools Beta 2

There you can generate POCO classes, derived DbContext and Code First mapping for an existing database in some clicks. It is very nice!

After installation some context menu options would be added to your Visual Studio.

Right-click on a C# project. Choose Entity Framework-> Reverse Engineer Code First (Generates POCO classes, derived DbContext and Code First mapping for an existing database):

Then choose your database and click OK. That's all! It is very easy.

You can do this by subsetting the data you pass into your merge:

merge(x = DF1, y = DF2[ , c("Client", "LO")], by = "Client", all.x=TRUE)

Or you can simply delete the column after your current merge :)

        ll = f.read().splitlines()
    d = {}
    for l in ll:
        k, v = re.split(r'==|>=', l)
        d[k] = v
    return d

def packageInfo():
    try:
        from pip._internal.operations import freeze
    except ImportError:
        from pip.operations import freeze

    d = {}
    for kv in freeze.freeze():
        k, v = re.split(r'==|>=', kv)
        d[k] = v
    return d

req = getpackver('requirements.txt')
pkginfo = packageInfo()

for k, v in req.items():
    print(f'{k:<16}: {v:<6} -> {pkginfo[k]}')

Here is my attempt to measure time difference in batch.

It respects the regional format of %TIME% without taking any assumptions on type of characters for time and decimal separators.

The code is commented but I will also describe it here.

It is flexible so it can also be used to normalize non-standard time values as well

The main function :timediff

:: timediff
:: Input and output format is the same format as %TIME%
:: If EndTime is less than StartTime then:
::   EndTime will be treated as a time in the next day
::   in that case, function measures time difference between a maximum distance of 24 hours minus 1 centisecond
::   time elements can have values greater than their standard maximum value ex: 12:247:853.5214
::   provided than the total represented time does not exceed 24*360000 centiseconds
::   otherwise the result will not be meaningful.
:: If EndTime is greater than or equals to StartTime then:
::   No formal limitation applies to the value of elements,
::   except that total represented time can not exceed 2147483647 centiseconds.

:timediff <outDiff> <inStartTime> <inEndTime>
(
    setlocal EnableDelayedExpansion
    set "Input=!%~2! !%~3!"
    for /F "tokens=1,3 delims=0123456789 " %%A in ("!Input!") do set "time.delims=%%A%%B "
)
for /F "tokens=1-8 delims=%time.delims%" %%a in ("%Input%") do (
    for %%A in ("@h1=%%a" "@m1=%%b" "@s1=%%c" "@c1=%%d" "@h2=%%e" "@m2=%%f" "@s2=%%g" "@c2=%%h") do (
        for /F "tokens=1,2 delims==" %%A in ("%%~A") do (
            for /F "tokens=* delims=0" %%B in ("%%B") do set "%%A=%%B"
        )
    )
    set /a "@d=(@h2-@h1)*360000+(@m2-@m1)*6000+(@s2-@s1)*100+(@c2-@c1), @sign=(@d>>31)&1, @d+=(@sign*24*360000), @h=(@d/360000), @d%%=360000, @m=@d/6000, @d%%=6000, @s=@d/100, @c=@d%%100"
)
(
    if %@h% LEQ 9 set "@h=0%@h%"
    if %@m% LEQ 9 set "@m=0%@m%"
    if %@s% LEQ 9 set "@s=0%@s%"
    if %@c% LEQ 9 set "@c=0%@c%"
)
(
    endlocal
    set "%~1=%@h%%time.delims:~0,1%%@m%%time.delims:~0,1%%@s%%time.delims:~1,1%%@c%"
    exit /b
)

Example:

@echo off
setlocal EnableExtensions
set "TIME="

set "Start=%TIME%"
REM Do some stuff here...
set "End=%TIME%"

call :timediff Elapsed Start End
echo Elapsed Time: %Elapsed%

pause
exit /b

:: put the :timediff function here

function prototype  :timediff <outDiff> <inStartTime> <inEndTime>

Input and output format is the same format as %TIME%

It takes 3 parameters from left to right:

Param1: Name of the environment variable to save the result to.
Param2: Name of the environment variable to be passed to the function containing StartTime string
Param3: Name of the environment variable to be passed to the function containing EndTime string

If EndTime is less than StartTime then:

EndTime will be treated as a time in the next day
in that case, the function measures time difference between a maximum distance of 24 hours minus 1 centisecond
time elements can have values greater than their standard maximum value ex: 12:247:853.5214
provided than the total represented time does not exceed 24*360000 centiseconds or (24:00:00.00) otherwise the result will not be meaningful.

No formal limitation applies to the value of elements,
except that total represented time can not exceed 2147483647 centiseconds.

Literal example with EndTime less than StartTime:

@echo off
setlocal EnableExtensions

set "start=23:57:33,12"
set "end=00:02:19,41"

call :timediff dif start end

echo Start Time: %start%
echo End Time:   %end%
echo,
echo Difference: %dif%
echo,

pause
exit /b

:: put the :timediff function here

Output:

Start Time: 23:57:33,12
End Time:   00:02:19,41

Difference: 00:04:46,29

Normalize non-standard time:

@echo off
setlocal EnableExtensions

set "start=00:00:00.00"
set "end=27:2457:433.85935"

call :timediff normalized start end

echo,
echo %end% is equivalent to %normalized%
echo,

pause
exit /b

:: put the :timediff function here

Output:

27:2457:433.85935 is equivalent to 68:18:32.35

Last bonus example:

@echo off
setlocal EnableExtensions

set "start=00:00:00.00"
set "end=00:00:00.2147483647"

call :timediff normalized start end

echo,
echo 2147483647 centiseconds equals to %normalized%
echo,

pause
exit /b

:: put the :timediff function here

Output:

2147483647 centiseconds equals to 5965:13:56.47

believe there should be a way in accessing file system.

Include node.d.ts using npm i @types/node. And then create a new tsconfig.json file (npx tsc --init) and create a .ts file as followed:

import fs from 'fs';
fs.readFileSync('foo.txt','utf8');

You can use other functions in fs as well : https://nodejs.org/api/fs.html

It is a Generic Type Parameter.

A generic type parameter allows you to specify an arbitrary type T to a method at compile-time, without specifying a concrete type in the method or class declaration.

For example:

public T[] Reverse<T>(T[] array)
{
    var result = new T[array.Length];
    int j=0;
    for(int i=array.Length - 1; i>= 0; i--)
    {
        result[j] = array[i];
        j++;
    }
    return result;
}

reverses the elements in an array. The key point here is that the array elements can be of any type, and the function will still work. You specify the type in the method call; type safety is still guaranteed.

So, to reverse an array of strings:

string[] array = new string[] { "1", "2", "3", "4", "5" };
var result = reverse(array);

Will produce a string array in result of { "5", "4", "3", "2", "1" }

This has the same effect as if you had called an ordinary (non-generic) method that looks like this:

public string[] Reverse(string[] array)
{
    var result = new string[array.Length];
    int j=0;
    for(int i=array.Length - 1; i >= 0; i--)
    {
        result[j] = array[i];
        j++;
    }
    return result;
}

The compiler sees that array contains strings, so it returns an array of strings. Type string is substituted for the T type parameter.

Generic type parameters can also be used to create generic classes. In the example you gave of a SampleCollection<T>, the T is a placeholder for an arbitrary type; it means that SampleCollection can represent a collection of objects, the type of which you specify when you create the collection.

So:

var collection = new SampleCollection<string>();

creates a collection that can hold strings. The Reverse method illustrated above, in a somewhat different form, can be used to reverse the collection's members.

Just get rid of the display: none; from your CSS. AngularJS is in control of showing/hiding that div.

If you want to hide it by default, just set the value of scope.myvalue to false initially - which you're already doing.

You should be able to rely on os.name.

import os
if os.name == 'nt':
    # ...

edit: Now I'd say the clearest way to do this is via the platform module, as per the other answer.

1. In the value or values you want to separate, enter the =NA() formula. This will appear that the value is skipped but the preceding and following data points will be joined by the series line.
2. Enter the data you want to skip in the same location as the original (row or column) but add it as a new series. Add the new series to your chart.
3. Format the new data point to match the original series format (color, shape, etc.). It will appear as though the data point was just skipped in the original series but will still show on your chart if you want to label it or add a callout.

One possible reason is that you have multiple python executables in your environment, for example 2.6.x, 2.7.x or virtaulenv. You might install the package into one of them and run your script with another.

Type python in the prompt, and press the tab key to see what versions of Python in your environment.

One issue I've had, and it was horribly tricky, was that the OCI call to describe a column attributes behaves diffrently depending on Oracle versions. Describing a simple NUMBER column created without any prec or scale returns differenlty on 9i, 1Og and 11g

A cookie is basically just an item in a dictionary. Each item has a key and a value. For authentication, the key could be something like 'username' and the value would be the username. Each time you make a request to a website, your browser will include the cookies in the request, and the host server will check the cookies. So authentication can be done automatically like that.

To set a cookie, you just have to add it to the response the server sends back after requests. The browser will then add the cookie upon receiving the response.

There are different options you can configure for the cookie server side, like expiration times or encryption. An encrypted cookie is often referred to as a signed cookie. Basically the server encrypts the key and value in the dictionary item, so only the server can make use of the information. So then cookie would be secure.

A browser will save the cookies set by the server. In the HTTP header of every request the browser makes to that server, it will add the cookies. It will only add cookies for the domains that set them. Example.com can set a cookie and also add options in the HTTP header for the browsers to send the cookie back to subdomains, like sub.example.com. It would be unacceptable for a browser to ever sends cookies to a different domain.

I like to share the code i'm using to transpose a splited text based on +bluefeet answer. In this aproach i'm implemented as a procedure in MS SQL 2005

    CREATE TABLE #tempSplitedTable (

    SET @query = 'select name, rowid, ' + @colsPivot + '

        (
          select ' + @columnToPivot + ' , name, value, ROW_NUMBER() over (partition by ' + @columnToPivot + ' order by ' + @columnToPivot + ') as rowid

        ) piv
        order by rowid'

    EXEC (@query)

    DROP TABLE #tempSplitedTable
END
GO

I'm mixing this solution with the information about howto order rows without order by (SQLAuthority.com) and the split function on MSDN (social.msdn.microsoft.com)

When you execute the prodecure

DECLARE @RC int
DECLARE @InputToSplit varchar(MAX)
DECLARE @Delimeter varchar(1)

set @InputToSplit = 'hello|beautiful|world'
set @Delimeter = '|'

EXECUTE @RC = [TransposeSplit] 
   @InputToSplit
  ,@Delimeter
GO

you obtaint the next result

  name       rowid  1      2          3
  col_value  1      hello  beautiful  world

I am running tests for my Angular app and encountered error Can't bind to 'routerLink' since it isn't a known property of 'a' as well.

I thought it might be useful to show my Angular dependencies:

    "@angular/animations": "^8.2.14",
    "@angular/common": "^8.2.14",
    "@angular/compiler": "^8.2.14",
    "@angular/core": "^8.2.14",
    "@angular/forms": "^8.2.14",
    "@angular/router": "^8.2.14",

The issue was in my spec file. I compared to another similar component spec file and found that I was missing RouterTestingModule in imports, e.g.

    TestBed.configureTestingModule({
      declarations: [
        ...
      ],
      imports: [ReactiveFormsModule, HttpClientTestingModule, RouterTestingModule],
      providers: [...]
    });
  });

Usually this happens if something is wrong with the byte array.

File.WriteAllBytes("filename.PDF", Byte[]);

This creates a new file, writes the specified byte array to the file, and then closes the file. If the target file already exists, it is overwritten.

Asynchronous implementation of this is also available.

public static System.Threading.Tasks.Task WriteAllBytesAsync 
(string path, byte[] bytes, System.Threading.CancellationToken cancellationToken = null);

If you are using AngularJS, and you are using Angular Bootstrap : https://angular-ui.github.io/bootstrap/

You can do this so nice like this :

HTML:

<nav id="header-navbar" class="navbar navbar-default" ng-class="{'navbar-fixed-top':scrollDown}" role="navigation" scroll-nav>
    <div class="container-fluid top-header">
        <!--- Rest of code --->
    </div>
</nav>

CSS: (Note here I use padding as bigger nav to shrink without padding you can modify as you want)

nav.navbar {
  -webkit-transition: all 0.4s ease;
  transition: all 0.4s ease;

  background-color: white;
  margin-bottom: 0;
  padding: 25px;
}

.navbar-fixed-top {
  padding: 0;
}

And then add your directive

Directive: (Note you may need to change this.pageYOffset >= 50 from 50 to more or less to fulfill your needs)

angular.module('app')
.directive('scrollNav', function ($window) {
  return function(scope, element, attrs) {
    angular.element($window).bind("scroll", function() {
      if (this.pageYOffset >= 50) {
        scope.scrollDown = true;
      } else {
        scope.scrollDown = false;
      }
      scope.$apply();
    });
  };
});

This will do the job nicely, animated and cool way.
