I don't think you need a case statement. You just need to update your where clause and make sure you have correct parentheses to group the clauses.

SELECT Sum(CAMount) as PaymentAmount 
from TableOrderPayment 
where (CStatus = 'Active' AND CPaymentType = 'Cash') 
OR (CStatus = 'Active' and CPaymentType = 'Check' and CDate<=SYSDATETIME())

The answers posted before mine assume that CDate<=SYSDATETIME() is also appropriate for Cash payment type as well. I think I split mine out so it only looks for that clause for check payments.

Null refers to an absence of data. Null is formally defined as a value that is unavailable, unassigned, unknown or inapplicable (OCA Oracle Database 12c, SQL Fundamentals I Exam Guide, p87). So, you may not see records with columns containing null values when said columns are restricted using an "in" or "not in" clauses.

I arrived here from a google search, since my other code is 'tidy' so leaving the 'tidy' way for anyone who else who may find it useful

library(dplyr)
iris %>% 
  mutate(Species = ifelse(as.character(Species) == "virginica", "newValue", as.character(Species)))

The case statement operator is like switch in the other languages.

This is the syntax of switch...case in C:

switch (expression)
?{
    case constant1:
      // statements
      break;
    case constant2:
      // statements
      break;
    .
    .
    .
    default:
      // default statements
}

This is the syntax of case...when in Ruby:

case expression
  when constant1, constant2 #Each when statement can have multiple candidate values, separated by commas.
     # statements 
     next # is like continue in other languages
  when constant3
     # statements 
     exit # exit is like break in other languages
  .
  .
  .
  else
     # statements
end

For example:

x = 10
case x
when 1,2,3
  puts "1, 2, or 3"
  exit
when 10
  puts "10" # it will stop here and execute that line
  exit # then it'll exit
else
  puts "Some other number"
end

For more information see the case documentation.

That's a case where you should use if clauses.

Multiple statements are to be separated by a new line:

If SkyIsBlue Then
  StartEngines
  Pollute
ElseIf SkyIsRed Then
  StopAttack
  Vent
ElseIf SkyIsYellow Then
  If Sunset Then
    Sleep
  ElseIf Sunrise or IsMorning Then
    Smoke
    GetCoffee
  Else
    Error
  End If
Else
  Joke
  Laugh
End If

Might be a bit odd or bad practice but this is one way of going about it.

(arg1, arg2, arg3) = (1, 2, 3)

if (arg1 == 1)*(arg2 == 2)*(arg3 == 3):
    print('Example.')

Anything multiplied by 0 == 0. If any of these conditions fail then it evaluates to false.

Yet another option (based on whether you want that if statement to be dynamically evaluated or not) is to use the C preprocessor, as described here.

IIF is not a standard SQL construct, but if it's supported by your database, you can achieve a more elegant statement producing the same result:

SELECT JobId, JobName,

COUNT(IIF (Priority=1, 1, NULL)) AS Priority1,
COUNT(IIF (Priority=2, 1, NULL)) AS Priority2,
COUNT(IIF (Priority=3, 1, NULL)) AS Priority3,
COUNT(IIF (Priority=4, 1, NULL)) AS Priority4,
COUNT(IIF (Priority=5, 1, NULL)) AS Priority5

FROM TableName
GROUP BY JobId, JobName

Think of ! (negation operator) as "not", || (boolean-or operator) as "or" and && (boolean-and operator) as "and". See Operators and Operator Precedence.

Thus:

if(!(a || b)) {
  // means neither a nor b
}

However, using De Morgan's Law, it could be written as:

if(!a && !b) {
  // is not a and is not b
}

a and b above can be any expression (such as test == 'B' or whatever it needs to be).

Once again, if test == 'A' and test == 'B', are the expressions, note the expansion of the 1st form:

// if(!(a || b)) 
if(!((test == 'A') || (test == 'B')))
// or more simply, removing the inner parenthesis as
// || and && have a lower precedence than comparison and negation operators
if(!(test == 'A' || test == 'B'))
// and using DeMorgan's, we can turn this into
// this is the same as substituting into if(!a && !b)
if(!(test == 'A') && !(test == 'B'))
// and this can be simplified as !(x == y) is the same as (x != y)
if(test != 'A' && test != 'B')

If $AccountNumber or $Balance is a node-set, then this behavior could easily happen. It's not because and is being treated as or.

For example, if $AccountNumber referred to nodes with the values 12345 and 66 and $Balance referred to nodes with the values 55 and 0, then $AccountNumber != '12345' would be true (because 66 is not equal to 12345) and $Balance != '0' would be true (because 55 is not equal to 0).

I'd suggest trying this instead:

<xsl:when test="not($AccountNumber = '12345' or $Balance = '0')">

$AccountNumber = '12345' or $Balance = '0' will be true any time there is an $AccountNumber with the value 12345 or there is a $Balance with the value 0, and if you apply not() to that, you will get a false result.

proceed = "y", "Y"
if answer in proceed:

Also, you don't want

answer = str(input("Is the information correct? Enter Y for yes or N for no"))

You want

answer = raw_input("Is the information correct? Enter Y for yes or N for no")

input() evaluates whatever is entered as a Python expression, raw_input() returns a string.

Edit: That is only true on Python 2. On Python 3, input is fine, although str() wrapping is still redundant.

Sorry, I wasn't sure which SQL platform you're talking about:

In MySQL:

$query = ("SELECT * FROM $db WHERE conditions AND LENGTH(col_name) = 3");

in MSSQL

$query = ("SELECT * FROM $db WHERE conditions AND LEN(col_name) = 3");

The LENGTH() (MySQL) or LEN() (MSSQL) function will return the length of a string in a column that you can use as a condition in your WHERE clause.

Edit

I know this is really old but thought I'd expand my answer because, as Paulo Bueno rightly pointed out, you're most likely wanting the number of characters as opposed to the number of bytes. Thanks Paulo.

So, for MySQL there's the CHAR_LENGTH(). The following example highlights the difference between LENGTH() an CHAR_LENGTH():

CREATE TABLE words (
    word VARCHAR(100)
) ENGINE INNODB DEFAULT CHARSET utf8mb4 COLLATE utf8mb4_unicode_ci;

INSERT INTO words(word) VALUES('??'), ('happy'), ('hayir');

SELECT word, LENGTH(word) as num_bytes, CHAR_LENGTH(word) AS num_characters FROM words;

+--------+-----------+----------------+
| word   | num_bytes | num_characters |
+--------+-----------+----------------+
| ??    |         6 |              2 |
| happy  |         5 |              5 |
| hayir  |         6 |              5 |
+--------+-----------+----------------+

Be careful if you're dealing with multi-byte characters.

Use CONCAT_WS().

SELECT CONCAT_WS(' ',firstname,lastname) as firstlast FROM users 
WHERE firstlast = "Bob Michael Jones";

The first argument is the separator for the rest of the arguments.

For others that stumble on this, you can also use ejs params/props in conditional statements:

recipes.js File:

app.get("/recipes", function(req, res) {
    res.render("recipes.ejs", {
        recipes: recipes
    });
});

recipes.ejs File:

<%if (recipes.length > 0) { %>
// Do something with more than 1 recipe
<% } %>

1. Select cell B3 and click the Conditional Formatting button in the ribbon and choose "New Rule".
2. Select "Use a formula to determine which cells to format"
3. Enter the formula: =IF(B2="X",IF(B3="Y", TRUE, FALSE),FALSE), and choose to fill green when this is true
4. Create another rule and enter the formula =IF(B2="X",IF(B3="W", TRUE, FALSE),FALSE) and choose to fill red when this is true.

More details - conditional formatting with a formula applies the format when the formula evaluates to TRUE. You can use a compound IF formula to return true or false based on the values of any cells.

Lets us assume you have a numpy array that has contains the value from 0 all the way up to 20 and you want to replace numbers greater than 10 with 0

import numpy as np

my_arr = np.arange(0,21) # creates an array
my_arr[my_arr > 10] = 0 # modifies the value

Note this will however modify the original array to avoid overwriting the original array try using arr.copy() to create a new detached copy of the original array and modify that instead.

import numpy as np

my_arr = np.arange(0,21)
my_arr_copy = my_arr.copy() # creates copy of the orignal array

my_arr_copy[my_arr_copy > 10] = 0 

Some basic regex would do the trick nicely for $some_variable !== 'uk' && $some_variable !== 'in':

if(!preg_match('/^uk|in$/', $some_variable)) {
    // Do something
}

Use empty(). It checks for both empty strings and null.

if (!empty($_POST['user'])) {
  // do stuff
}

From the manual:

The following things are considered to be empty:

"" (an empty string)  
0 (0 as an integer)  
0.0 (0 as a float)  
"0" (0 as a string)    
NULL  
FALSE  
array() (an empty array)  
var $var; (a variable declared, but without a value in a class)  

Try negation operator ! before $(this):

if (!$(this).parent().next().is('ul')){

You could just add a few COUNTIF statements together:

=COUNTIF(A1:A196,"yes")+COUNTIF(A1:A196,"no")+COUNTIF(J1:J196,"agree")

This will give you the result you need.

EDIT

Sorry, misread the question. Nicholas is right that the above will double count. I wasn't thinking of the AND condition the right way. Here's an alternative that should give you the correct results, which you were pretty close to in the first place:

=SUM(COUNTIFS(A1:A196,{"yes","no"},J1:J196,"agree"))

You could just compare your string to the empty string:

if variable != "":
    etc.

But you can abbreviate that as follows:

if variable:
    etc.

Explanation: An if actually works by computing a value for the logical expression you give it: True or False. If you simply use a variable name (or a literal string like "hello") instead of a logical test, the rule is: An empty string counts as False, all other strings count as True. Empty lists and the number zero also count as false, and most other things count as true.

{ } -->

defines scope, so if(a==1) { int b = 10; } says, you are defining int b, for {}- this scope. For

if(a==1)
  int b =10;

there is no scope. And you will not be able to use b anywhere.

My Code Is Very Easy To Understand

var year = 2015;
var LeapYear = year % 4;

if (LeapYear==0) {
    alert("This is Leap Year");
} else {
    alert("This is not leap year");
}

A pretty simple solution I came up with: (Python 3)

def only_letters(tested_string):
    for letter in tested_string:
        if letter not in "abcdefghijklmnopqrstuvwxyz":
            return False
    return True

You can add a space in the string you are checking against if you want spaces to be allowed.

I would use lambda function on a Series of a DataFrame like this:

f = lambda x: 0 if x>100 else 1
df['my_column'] = df['my_column'].map(f)

I do not assert that this is an efficient way, but it works fine.

try this

mysql_query("
SELECT * FROM Drinks WHERE
    email='$Email'
    AND date='$Date_Today'
    OR date='$Date_Yesterday', '$Date_TwoDaysAgo', '$Date_ThreeDaysAgo', '$Date_FourDaysAgo', '$Date_FiveDaysAgo', '$Date_SixDaysAgo', '$Date_SevenDaysAgo'"     
   );

my be like this

 OR date='$Date_Yesterday' oR '$Date_TwoDaysAgo'.........

Yeah, it's typically because it starts out as 'where 1 = 0', to force the statement to fail.

It's a more naive way of wrapping it up in a transaction and not committing it at the end, to test your query. (This is the preferred method).

A small note about the efficiency of abovementioned methods:

 library(microbenchmark)

  microbenchmark(
    which("Feb" == month.abb)[[1]],
    which(month.abb %in% "Feb"))

  Unit: nanoseconds
   min     lq    mean median     uq  max neval
   891  979.0 1098.00   1031 1135.5 3693   100
   1052 1175.5 1339.74   1235 1390.0 7399  100

So, the best one is

    which("Feb" == month.abb)[[1]]

Assume you were:

1. Reading a network file and got disconnected.
2. Reading a local file that was no longer available.
3. Using some stream to read data and some other process closed the stream.
4. Trying to read/write a file, but don't have permission.
5. Trying to write to a file, but disk space was no longer available.

There are many more examples, but these are the most common, in my experience.

There are 2 options to find matching text; string.match or string.find.

Both of these perform a regex search on the string to find matches.

string.find()

string.find(subject string, pattern string, optional start position, optional plain flag)

Returns the startIndex & endIndex of the substring found.

The plain flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger) being interpreted as a regex capture group matching for tiger, it instead looks for (tiger) within a string.

Going the other way, if you want to regex match but still want literal special characters (such as .()[]+- etc.), you can escape them with a percentage; %(tiger%).

You will likely use this in combination with string.sub

Example

str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

string.match()

string.match(s, pattern, optional index)

Returns the capture groups found.

Example

str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

I searched for help on this topic as I came across the same issue.

Although the following may not be the Answer to the question asked originally in 2012 it may be a solution for those who come across this thread.

A way to solve this is to check where your project is within the solution. It turns out for my instance (I was trying to install a NuGet package but it wouldn't and the listed error came up) that my project file was not included within the solution directory although showing in the solution explorer. I deleted the project from the directory out of scope and re-added the project but this time within the correct location.

There is a major gotcha associated with getting an ASCII code of a char value.

In the proper sense, it can't be done.

It's because char has a range of 65535 whereas ASCII is restricted to 128. There is a huge amount of characters that have no ASCII representation at all.

The proper way would be to use a Unicode code point which is the standard numerical equivalent of a character in the Java universe.

Thankfully, Unicode is a complete superset of ASCII. That means Unicode numbers for Latin characters are equal to their ASCII counterparts. For example, A in Unicode is U+0041 or 65 in decimal. In contrast, ASCII has no mapping for 99% of char-s. Long story short:

char ch = 'A';
int cp = String.valueOf(ch).codePointAt(0);

Furthermore, a 16-bit primitive char actually represents a code unit, not a character and is thus restricted to Basic Multilingual Plane, for historical reasons. Entities beyond it require Character objects which deal away with the fixed bit-length limitation.

Personally, I ran these exact steps:

* Install Interop Assemblies: you can install from Microsoft's website https://www.microsoft.com/en-us/download/details.aspx?id=3508&tduid=(09cd06700e5e2553aa540650ec905f71)(256380)(2459594)(TnL5HPStwNw-yuTjfb1FeDiXvvZxhh.R.Q)()

* Check assemblies version: check the version of the assemblies on development and production machines. The assemblies will be in the GAC, in widows 7 this folder is %windir%\assembly.

* Create a Desktop folder: the service uses the desktop folder under systemprofile so you will need to create this folder if not there, here is the location of the folder: For 64 bit applications : C:\Windows\SysWOW64\config\systemprofile\Desktop For 32 bit applications : C:\Windows\System32\config\systemprofile\Desktop

* Add DCOM user permissions:
---start the run window and type 'dcomcnfg'.
---Expand Component Services –> Computers –> My Computer –> DCOM Config.
---Look for Microsoft Excel Application. Right click on it and select properties, then select the Security tab.
---Select the Customize radio button under 'Launch and Activation Permissions' and 'Access Permission' and click the Edit button for both to add users as follows.
---------Click the Add button and users 'IIS_IUSRS' and 'NETWORK SERVICE' and give them full privileges.
---Go to the Identity tab and select "The interactive user" option.
---Click Apply and OK.

setx FOOBAR ""

just causes the value of FOOBAR to be a null string. (Although, it shows with the set command with the "" so maybe double-quotes is the string.)

I used:

set FOOBAR=

and then FOOBAR was no longer listed in the set command. (Log-off was not required.)

Windows 7 32 bit, using the command prompt, non-administrator is what I used. (Not cmd or Windows + R, which might be different.)

BTW, I did not see the variable I created anywhere in the registry after I created it. I'm using RegEdit not as administrator.

Use for, something along the lines of:

set content=
for /f "delims=" %%i in ('filename') do set content=%content% %%i

Maybe you’ll have to do setlocal enabledelayedexpansion and/or use !content! rather than %content%. I can’t test, as I don’t have any MS Windows nearby (and I wish you the same :-).

The best batch-file-black-magic-reference I know of is at http://www.rsdn.ru/article/winshell/batanyca.xml. If you don’t know Russian, you still could make some use of the code snippets provided.

Remove Windows Service via Registry

Its very easy to remove a service from registry if you know the right path. Here is how I did that:

1. Run Regedit or Regedt32

2. Go to the registry entry "HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services"

3. Look for the service that you want delete and delete it. You can look at the keys to know what files the service was using and delete them as well (if necessary).

Delete Windows Service via Command Window

Alternatively, you can also use command prompt and delete a service using following command:

sc delete

You can also create service by using following command

sc create "MorganTechService" binpath= "C:\Program Files\MorganTechSPace\myservice.exe"

Note: You may have to reboot the system to get the list updated in service manager.

You could also use wp_list_categories();

wp_list_categories( array('taxonomy' => 'product_cat', 'title_li'  => '') );

See "Can I Use" for the full list of IE11 Flexbox bugs and more

There are numerous Flexbox bugs in IE11 and other browsers - see flexbox on Can I Use -> Known Issues, where the following are listed under IE11:

• IE 11 requires a unit to be added to the third argument, the flex-basis property
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property
• IE 11 does not vertically align items correctly when min-height is used

Also see Philip Walton's Flexbugs list of issues and workarounds.

There isn't a magic bullet solution for what you're looking for, unfortunately. Here's what you can do:

• create an Interface class using this command in the Visual Studio Command Prompt window:

  wsdl.exe yourFile.wsdl /l:CS /serverInterface
  Use VB or CS for your language of choice. This will create a new .cs or .vb file.

• Create a new .NET Web Service project. Import Existing File into your project - the file that was created in the step above.

• In your .asmx.cs file in Code-View, modify your class as such:

 public class MyWebService : System.Web.Services.WebService, IMyWsdlInterface
 {    
     [WebMethod]
     public string GetSomeString()
     {
         //you'll have to write your own business logic 
         return "Hello SOAP World";
     }
 }

Here's a simple way

for (i in 1:10) {
  
  skip_to_next <- FALSE
  
  # Note that print(b) fails since b doesn't exist
  
  tryCatch(print(b), error = function(e) { skip_to_next <<- TRUE})
  
  if(skip_to_next) { next }     
}

Note that the loop completes all 10 iterations, despite errors. You can obviously replace print(b) with any code you want. You can also wrap many lines of code in { and } if you have more than one line of code inside the tryCatch

use the HorizontalContentAlignment property.

Sample

<Label HorizontalContentAlignment="Center"/>

You can use flexbox for this.

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

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

I know it has been a long time since the original question was posted. But i think for slow ones like me a bit of explanation of @Heisenberg's answer would help.

Declare two variable in the adapter class as

private int mExpandedPosition= -1;
private RecyclerView recyclerView = null;

Then in onBindViewHolder following as given in the original answer.

      // This line checks if the item displayed on screen 
      // was expanded or not (Remembering the fact that Recycler View )
      // reuses views so onBindViewHolder will be called for all
      // items visible on screen.
    final boolean isExpanded = position==mExpandedPosition;

        //This line hides or shows the layout in question
        holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);

        // I do not know what the heck this is :)
        holder.itemView.setActivated(isExpanded);

        // Click event for each item (itemView is an in-built variable of holder class)
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

 // if the clicked item is already expaned then return -1 
//else return the position (this works with notifyDatasetchanged )
                mExpandedPosition = isExpanded ? -1:position;
    // fancy animations can skip if like
                TransitionManager.beginDelayedTransition(recyclerView);
    //This will call the onBindViewHolder for all the itemViews on Screen
                notifyDataSetChanged();
            }
        });

And lastly to get the recyclerView object in the adapter override

@Override
public void onAttachedToRecyclerView(@NonNull RecyclerView recyclerView) {
    super.onAttachedToRecyclerView(recyclerView);

    this.recyclerView = recyclerView;
}

Hope this Helps.

Android documentation is clear on this.Go to the below page.Underneath,there are two columns with names "OLD BUILD ARTIFACT" and "AndroidX build artifact"

https://developer.android.com/jetpack/androidx/migrate

Now you have many dependencies in gradle.Just match those with Androidx build artifacts and replace them in the gradle.

That won't be enough.

Go to your MainActivity (repeat this for all activities) and remove the word AppCompact Activity in the statement "public class MainActivity extends AppCompatActivity " and write the same word again.But this time androidx library gets imported.Until now appcompact support file got imported and used (also, remove that appcompact import statement).

Also,go to your layout file. Suppose you have a constraint layout,then you can notice that the first line constraint layout in xml file have something related to appcompact.So just delete it and write Constraint layout again.But now androidx related constraint layout gets added.

repeat this for as many activities and as many xml layout files..

But don't worry: Android Studio displays all such possible errors while compiling.

Something as simple as this will work

awk 'BEGIN{system("echo hello")}'

and

awk 'BEGIN { system("date"); close("date")}'

Switch value must have an Integral type. Also, since you know that differenciating character is in position 7, you could switch on a.at(7). But you are not sure the user entered 8 characters. He may as well have done some typing mistake. So you are to surround your switch statement within a Try Catch. Something with this flavour

#include<iostream>
using namespace std;
int main() {
    string a;
    cin>>a;

    try
    {
    switch (a.at(7)) {
    case '1':
        cout<<"It pressed number 1"<<endl;
        break;
    case '2':
        cout<<"It pressed number 2"<<endl;
        break;
    case '3':
        cout<<"It pressed number 3"<<endl;
        break;
    default:
        cout<<"She put no choice"<<endl;
        break;
    }
    catch(...)
    {

    }
    }
    return 0;
}

The default clause in switch statement captures cases when users input is at least 8 characters, but not in {1,2,3}.

Alternatively, you can switch on values in an enum.

EDIT

Fetching 7th character with operator[]() does not perform bounds check, so that behavior would be undefined. we use at() from std::string, which is bounds-checked, as explained here.

Where ever you need to text in one line put this code

white-space:nowrap

You have several techniques to do it.

This post - read the part about the revert will explain in details what we want to do and how to do it.

Here is the most simple solution to your problem:

# Checkout the desired branch
git checkout <branch>

# Undo the desired commit
git revert <commit>

# Update the remote with the undo of the code
git push origin <branch>

The revert command will create a new commit with the undo of the original commit.

Insert mode has no such command, unfortunately. In VIM, to delete the whole word under the cursor you may type viwd in NORMAL mode. Which means "Visual-block Inner Word Delete". Use an upper case W to include punctuation.

So the answer to your question is, it depends on whether you want it in installed into your local repo. Install will also run package because it's higher up in the goal phase stack.

Try pytest -s -v test_login.py for more info in console.

-v it's a short --verbose

-s means 'disable all capturing'

With me I have a UIViewcontroller, and into it I have a tableview with a custom cell on it. I map my outlet of UILabel into UItableviewcell to the UIViewController then got the error.

Hi you can use URLSearchParams, you can read more about it here.

import:

import {URLSearchParams} from "@angular/http";

and function:

getParam(){
  let params = new URLSearchParams(window.location.search);
  let someParam = params.get('someParam');
  return someParam;
}

Notice: It's not supported by all platforms and seems to be in "EXPERIMENTAL" state by angular docs

use res.json, ajax, and promises, with a nice twist of localStorage to use it anywhere, added with tokens for that rare arcade love. PS, you could use cookies, but cookies can bite on https.

webpage.js

function (idToken) {
    $.ajax({
        url: '/main',
        headers: {
            Authorization: 'Bearer ' + idToken
        },
        processData: false,
    }).done(function (data) {
        localStorage.setItem('name', data.name);
        //or whatever you want done.
    }).fail(function (jqXHR, textStatus) {
        var msg = 'Unable to fetch protected resource';
        msg += '<br>' + jqXHR.status + ' ' + jqXHR.responseText;
        if (jqXHR.status === 401) {
            msg += '<br>Your token may be expired'
        }
        displayError(msg);
    });

server.js, using express()

app.get('/main',
passport.authenticate('oauth2-jwt-bearer', { session: false }),
function (req, res) {
    getUserInfo(req) //get your information to use it.
        .then(function (userinfo) {  //return your promise
            res.json({ "name": userinfo.Name});
            //you can declare/return more vars in this res.json.
            //res.cookie('name', name); //https trouble
        })
    .error(function (e) {console.log("Error handler " + e)})
    .catch(function (e) {console.log("Catch handler " + e)});
});

You can use command

svn add * force--

or

svn add <directory/file name>

If your files/directories are not adding recursively. Then check this.

Recursive adding is default property. You can see in SVN book.

Issue can be in your ignore list or global properties.

I got solution google issue tracker

Check global properties for ignoring star(*)

• Right click in your repo in window. Select TortoiseSVN > Properties.
• See if you don't have a property svn:global-ignores with a value of *
• If you have property with star(*) then it will ignore recursive adding. So remove this property.

Check global ignore pattern for ignoring star(*)

• Right click in your repo in window. Select TortoiseSVN > Settings > General.
• See in Global Ignore Pattern, if you don't have set star(*) there.
• If you found star(*), remove this property.

This guy also explained why this property added in my project.

The most like way that it got there is that someone right-clicked a file without any extension and selected TortoiseSVN -> SVN Ignore -> * (recursively), and then committed this.

You can check the log to see who committed that property change, find out what they were actually trying to do, and ask them to be more careful in future. :)

Someone's going to post a much better answer than this, but just wanted to make the point that personally I would never store a phone number in any kind of integer field, mainly because:

1. You don't need to do any kind of arithmetic with it, and
2. Sooner or later someone's going to try to (do something like) put brackets around their area code.

In general though, I seem to almost exclusively use:

• INT(11) for anything that is either an ID or references another ID
• DATETIME for time stamps
• VARCHAR(255) for anything guaranteed to be under 255 characters (page titles, names, etc)
• TEXT for pretty much everything else.

Of course there are exceptions, but I find that covers most eventualities.

First, don't use * in select, affects their performance and hinder the use of the group by and order by. Try this query:

SELECT wp_posts.post_author, wp_posts.post_date as pdate FROM wp_posts
WHERE wp_posts.post_status='publish'
AND wp_posts.post_type='post'
GROUP BY wp_posts.post_author           
ORDER BY pdate DESC

When you don't specifies the table in ORDER BY, just the alias, they will order the result of the select.

Your'e almost there, you just need to get the properties from the type, rather than expect the properties to be accessible in the form of a collection or property bag:

var property in obj.GetType().GetProperties()

From there you can access like so:

property.Name
property.GetValue(obj, null)

With GetValue the second parameter will allow you to specify index values, which will work with properties returning collections - since a string is a collection of chars, you can also specify an index to return a character if needs be.

The following is a solution for MySQL (not SQL Server), i couldn't easily find a solution to this on stackoverflow for mysql, so i figured maybe this could help someone...

GLHF!

If your table is separated by others than tabs, you should specify it like...

LOAD DATA LOCAL 
    INFILE '/tmp/mydata.txt' INTO TABLE PerformanceReport 
    COLUMNS TERMINATED BY '\t'  ## This should be your delimiter
    OPTIONALLY ENCLOSED BY '"'; ## ...and if text is enclosed, specify here

string left = "411329_SOFT_MAC_GREEN";
string right= "SOFT_MAC_GREEN";

string[] l = left.Split('_');
string[] r = right.Split('_');

string[] distinctLeft = l.Distinct().ToArray();
string[] distinctRight = r.Distinct().ToArray();

var commonWord = l.Except(r, StringComparer.OrdinalIgnoreCase)
string result = String.Join("_",commonWord);
result = "411329"

As an alternative to writing to a file, how about writing to a table? Instead of calling DBMS_OUTPUT.PUT_LINE you could call your own DEBUG.OUTPUT procedure something like:

procedure output (p_text varchar2) is
   pragma autonomous_transaction;
begin
   if g_debugging then
      insert into debug_messages (username, datetime, text)
      values (user, sysdate, p_text);
      commit;
   end if;
end;

The use of an autonomous transaction allows you to retain debug messages produced from transactions that get rolled back (e.g. after an exception is raised), as would happen if you were using a file.

The g_debugging boolean variable is a package variable that can be defaulted to false and set to true when debug output is required.

Of course, you need to manage that table so that it doesn't grow forever! One way would be a job that runs nightly/weekly and deletes any debug messages that are "old".

Write this code

<?php
    if(isset($_POST['submit'])){
        echo 'Hello World';
    } 
?>

<html>
     <body>
         <form method="post">
             <input type="text" name="studentname">
             <input type="submit" name="submit" value="click">
         </form>
     </body>
</html>

All have explained in great detail and nothing I could add further. Though I would like to explain it in Layman's Terms or plain ENGLISH

1.9 is less precise than 1.99
1.99 is less precise than 1.999
1.999 is less precise than 1.9999

.....

A variable, able to store or represent "1.9" provides less precision than the one able to hold or represent 1.9999. These Fraction can amount to a huge difference in large calculations.

Use the "not" selector.

For example, instead of:

$(".thumbs").hover()

try:

$(".thumbs:not(.selected)").hover()

You must need to specify columns name which you want to insert if there is an Identity column. So the command will be like this below:

SET IDENTITY_INSERT DuplicateTable ON

INSERT Into DuplicateTable ([IdentityColumn], [Column2], [Column3], [Column4] ) 
SELECT [IdentityColumn], [Column2], [Column3], [Column4] FROM MainTable

SET IDENTITY_INSERT DuplicateTable OFF

If your table has many columns then get those columns name by using this command.

SELECT column_name + ','
FROM   information_schema.columns 
WHERE  table_name = 'TableName'
for xml path('')

(after removing the last comma(',')) Just copy past columns name.

Compare the length using lengthB and length function in oracle.

SELECT * FROM test WHERE length(sampletext) <> lengthb(sampletext)

include dirname(__FILE__).'/../../index.php';

is your best bet here, and it will avoid most of the relative path bugs you can encounter with other solutions.

Indeed, it will force the include to always be relative to the position of the current script where this code is placed (which location is most likely stable, since you define the architecture of your application). This is different from just doing include '../../index.php' which will include relatively to the executing (also named "calling") script and then relatively to the current working directory, which will point to the parent script that includes your script, instead of resolving from your included script's path.

From the PHP documentation:

Files are included based on the file path given or, if none is given, the include_path specified. If the file isn't found in the include_path, include will finally check in the calling script's own directory and the current working directory before failing.

And the oldest post I've found citing this trick dates back to 2003, by Tapken.

You can test with the following setup:

Create a layout like this:

htdocs
¦   parent.php
¦   goal.php
¦
+---sub
    ¦   included.php
    ¦   goal.php

In parent.php, put:

<?php
include dirname(__FILE__).'/sub/included.php';
?>

In sub/included.php, put:

<?php
print("WRONG : " . realpath('goal.php'));
print("GOOD : " . realpath(dirname(__FILE__).'/goal.php'));
?>

Result when accessing parent.php:

WRONG : X:\htdocs\goal.php
GOOD : X:\htdocs\sub\goal.php

As we can see, in the first case, the path is resolved from the calling script parent.php, while by using the dirname(__FILE__).'/path' trick, the include is done from the script included.php where the code is placed in.

Beware, the following NOT equivalent to the trick above contrary to what can be read elsewhere:

include '/../../index.php';

Indeed, prepending / will work, but it will resolve just like include ../../index.php from the calling script (the difference is that include_path won't be looked afterwards if it fails). From PHP doc:

If a path is defined — whether absolute (starting with a drive letter or \ on Windows, or / on Unix/Linux systems) or relative to the current directory (starting with . or ..) — the include_path will be ignored altogether.

It's due to you sending one object, and you're expecting two parameters.

Try this and you'll see:

public class UserDetails
{
   public string username { get; set; }
   public string password { get; set; }
}

public JsonResult Login(UserDetails data)
{
   string error = "";
   //the rest of your code
}

Just use the formula

120 = (HOUR(A8)*3600+MINUTE(A8)*60+SECOND(A8))/60

i.e we need to take multiple email addresses separated by comma, spaces or newline as below.

    var emails = EmailText.replace(","," ").replace("\n"," ").replace(" ","").split(" ");
    for(var i in emails)
        emails[i] = emails[i].replace(/(\r\n|\n|\r)/gm,"");

    emails.filter(Boolean);
    console.log(emails);

This is quite useful question. I think that my solution on Windows 10 PHP7 is rather useful for people who have yet some UTF-8 conversion trouble.

Here are my steps. The PHP script calling the following function, here named utfsave.php must have UTF-8 encoding itself, this can be easily done by conversion on UltraEdit.

In utfsave.php, we define a function calling PHP fopen($filename, "wb"), ie, it's opened in both w write mode, and especially with b in binary mode.

<?php
//
//  UTF-8 ??:
//
// fnc001: save string as a file in UTF-8:
// The resulting file is UTF-8 only if $strContent is,
// with French accents, chinese ideograms, etc..
//
function entSaveAsUtf8($strContent, $filename) {
  $fp = fopen($filename, "wb"); 
  fwrite($fp, $strContent);
  fclose($fp);
  return True;
}

//
// 0. write UTF-8 string in fly into UTF-8 file:
//
$strContent = "My string contains UTF-8 chars ie ???? for un été en France";

$filename = "utf8text.txt";

entSaveAsUtf8($strContent, $filename);


//
// 2. convert CP936 ANSI/OEM - chinese simplified GBK file into UTF-8 file:
//
$strContent = file_get_contents("cp936gbktext.txt");
$strContent = mb_convert_encoding($strContent, "UTF-8", "CP936");


$filename = "utf8text2.txt";

entSaveAsUtf8($strContent, $filename);

?>

The source file cp936gbktext.txt file content:

>>Get-Content cp936gbktext.txt
My string contains UTF-8 chars ie ???? for un été en France 936 (ANSI/OEM - chinois simplifié GBK)

Running utf8save.php on Windows 10 PHP, thus created utf8text.txt, utf8text2.txt files will be automatically saved in UTF-8 format.

With this method, BOM char is not required. BOM solution is bad because it causes troubles when we do sourcing an sql file for MySQL for example.

It's worth noting that I failed making work file_put_contents($filename, utf8_encode($mystring)); for this purpose.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

If you cannot guess, you try one by one, as mb_detect_encoding() cannot do the job easily.

"Unicode" is unfortunately used in various different ways, depending on the context. Its most correct use (IMO) is as a coded character set - i.e. a set of characters and a mapping between the characters and integer code points representing them.

UTF-8 is a character encoding - a way of converting from sequences of bytes to sequences of characters and vice versa. It covers the whole of the Unicode character set. ASCII is encoded as a single byte per character, and other characters take more bytes depending on their exact code point (up to 4 bytes for all currently defined code points, i.e. up to U-0010FFFF, and indeed 4 bytes could cope with up to U-001FFFFF).

When "Unicode" is used as the name of a character encoding (e.g. as the .NET Encoding.Unicode property) it usually means UTF-16, which encodes most common characters as two bytes. Some platforms (notably .NET and Java) use UTF-16 as their "native" character encoding. This leads to hairy problems if you need to worry about characters which can't be encoded in a single UTF-16 value (they're encoded as "surrogate pairs") - but most developers never worry about this, IME.

Some references on Unicode:

• The Unicode consortium web site and in particular the tutorials section
• Joel's article
• My own article (.NET-oriented)

Simply:

/^([^0-9]*)$/

That pattern matches any number of characters that is not 0 through 9.

I know as for Appium Mobile Automation you need .app file to run ios app on Simulator.So as like me many of you face this problem. So I explain how to create that .app file and where it is located.

1.Open Xcode.

2.Click on your sample project.(If you don't have then click on create new xcode project)

3.In left panel inside screen you will see products folder then click and expand that, you will see the list.

4. Then right click on .app file and click on Show in Finder and thats your .app file. Now you can copy or use that path in capabilities for appium desktop or in framework.

JSX tags (<Component/>) are clearly not standard javascript and have no special meaning if you put them inside a naked <script> tag for example. Hence all React files that contain them are JSX and not JS.

By convention, the entry point of a React application is usually .js instead of .jsx even though it contains React components. It could as well be .jsx. Any other JSX files usually have the .jsx extension.

In any case, the reason there is ambiguity is because ultimately the extension does not matter much since the transpiler happily munches any kinds of files as long as they are actually JSX.

My advice would be: don't worry about it.

4) Build Path

5) Select Configure Build Path

6) Click on Add external JARs...

7) C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib

8) Here you will get ojdbc14.jar

9) select here

10) open

11) ok

save and run the program you will get output.

You should always try to use a composite object with concrete types (using composite design pattern) rather than a list of object types. Who would remember what the heck each of those objects is? Think about maintenance of your code later on... Instead, try something like this:

Public (Class or Structure) MyPerson
                public string FirstName { get; set; }
                public string LastName { get; set; }
                public string Address { get; set; }
                public int ZipCode { get; set; }
End Class

And then:

Dim person as new MyPerson With { .FirstName = “Joe”,
                                  .LastName = "Smith”,
                                  ...
                                 }
backgroundWorker1.RunWorkerAsync(person)

and then:

private void backgroundWorker1_DoWork (object sender, DoWorkEventArgs e)
{
        MyPerson person = e.Argument as MyPerson
        string firstname = person.FirstName;
        string lastname = person.LastName;
        int zipcode = person.ZipCode;                                 
}

It is important to note that each jQuery() call must actually return. If an exception is thrown in one, subsequent (unrelated) calls will never be executed.

This applies regardless of syntax. You can use jQuery(), jQuery(function() {}), $(document).ready(), whatever you like, the behavior is the same. If an early one fails, subsequent blocks will never be run.

This was a problem for me when using 3rd-party libraries. One library was throwing an exception, and subsequent libraries never initialized anything.

Beside all the above hints like track by and smaller loops, this one also helped me a lot

<span ng-bind="::stock.name"></span>

this piece of code would print the name once it has been loaded, and stop watching it after that. Similarly, for ng-repeats, it could be used as

<div ng-repeat="stock in ::ctrl.stocks">{{::stock.name}}</div>

however it only works for AngularJS version 1.3 and higher. From http://www.befundoo.com/blog/optimizing-ng-repeat-in-angularjs/

Thanks to unutbu for the explanation. By default numpy.cov calculates the sample covariance. To obtain the population covariance you can specify normalisation by the total N samples like this:

Covariance = numpy.cov(a, b, bias=True)[0][1]
print(Covariance)

or like this:

Covariance = numpy.cov(a, b, ddof=0)[0][1]
print(Covariance)

Code is

public class TranslateNumberToWord {

/**
 * Translate
 * 
 * @param ctryCd
 * @param lang
 * @param reqStr
 * @param fractionUnitName
 * @return
 */
public static String translate(String ctryCd, String lang, String reqStr, String fractionUnitName) {
    StringBuffer result = new StringBuffer();

    Locale locale = new Locale(lang, ctryCd);
    Currency crncy = Currency.getInstance(locale);

    String inputArr[] = StringUtils.split(new BigDecimal(reqStr).abs().toPlainString(), ".");
    RuleBasedNumberFormat rule = new RuleBasedNumberFormat(locale, RuleBasedNumberFormat.SPELLOUT);

    int i = 0;
    for (String input : inputArr) {
        CurrencyAmount crncyAmt = new CurrencyAmount(new BigDecimal(input), crncy);
        if (i++ == 0) {
            result.append(rule.format(crncyAmt)).append(" " + crncy.getDisplayName() + " and ");
        } else {
            result.append(rule.format(crncyAmt)).append(" " + fractionUnitName + " ");
        }
    }
    return result.toString();
}

public static void main(String[] args) {
    String ctryCd = "US";
    String lang = "en";
    String input = "95.17";

    String result = translate(ctryCd, lang, input, "Cents");
    System.out.println("Input: " + input + " result: " + result);
}}

Tested with quite a big number and output would be

Input: 95.17 result: ninety-five US Dollar and seventeen Cents
Input: 999999999999999999.99 result: nine hundred ninety-nine quadrillion nine hundred ninety-nine trillion nine hundred ninety-nine billion nine hundred ninety-nine million nine hundred ninety-nine thousand nine hundred ninety-nine US Dollar and ninety-nine Cents 

If i understand you correctly then in c# the yield return compiler magic is all you need i think.

e.g.

IEnumerable<string> myMethod(IEnumerable<string> sequence)
{
    foreach(string item in sequence)
    {
         yield return item + "roxxors";
    }
}

From your local machine:

rsync -chavzP --stats [email protected]:/path/to/copy /path/to/local/storage

From your local machine with a non standard ssh port:

rsync -chavzP -e "ssh -p $portNumber" [email protected]:/path/to/copy /local/path

Or from the remote host, assuming you really want to work this way and your local machine is listening on SSH:

rsync -chavzP --stats /path/to/copy [email protected]:/path/to/local/storage

See man rsync for an explanation of my usual switches.

%u prints unsigned integer

%d prints signed integer

to get a pointer address use %p

Other List of Formatting Escapes:

Here are the full list of formatting escapes. I am just giving a screen shot from this page

Use the following css:

* {
    font: Verdana, Arial, 'sans-serif' !important;/* <-- fonts */
}

The *-selector means any/all elements, but will obviously be on the bottom of the food chain when it comes to overriding more specific selectors.

Note that the !important-flag will render the font-style for * to be absolute, even if other selectors have been used to set the text (for example, the body or maybe a p).

I came across this, tot it would be nice to share...

What do you guys think?

$(document).ready(function() {
  window.mousemove = function(e) {
    p = $(e).position();  //remember $(e) - could be any html tag also.. 
    left = e.left;        //retrieving the left position of the div... 
    top = e.top;          //get the top position of the div... 
  }
});

and boom, there we have it..

List<String> l = new ArrayList<String>(listOfTopicAuthors);

My solution is to get complete log the first time the application start, like:

heroku logs -n 1500 > log

then add fgrep -vf to keep it up to date, like:

heroku logs -n 1500 > newlog ; fgrep -vf log newlog >> log

for continuous logging, just iterate it using watch for every x minutes (or seconds).

Here's a lambda solution not as user-friendly as @Paul Croarkin's in one way (the level is effectively passed twice). But I think (a) the user should pass the Logger; and (b) AFAIU the original question was not asking for a convenient way for everywhere in the application, only a situation with few usages inside a library.

package test.lambda;
import java.util.function.*;
import org.slf4j.*;

public class LoggerLambda {
    private static final Logger LOG = LoggerFactory.getLogger(LoggerLambda.class);

    private LoggerLambda() {}

    public static void log(BiConsumer<? super String, ? super Object[]> logFunc, Supplier<Boolean> logEnabledPredicate, 
            String format, Object... args) {
        if (logEnabledPredicate.get()) {
            logFunc.accept(format, args);
        }
    }

    public static void main(String[] args) {
        int a = 1, b = 2, c = 3;
        Throwable e = new Exception("something went wrong", new IllegalArgumentException());
        log(LOG::info, LOG::isInfoEnabled, "a = {}, b = {}, c = {}", a, b, c);

        // warn(String, Object...) instead of warn(String, Throwable), but prints stacktrace nevertheless
        log(LOG::warn, LOG::isWarnEnabled, "error doing something: {}", e, e);
    }
}

Since slf4j allows a Throwable (whose stack trace should be logged) inside the varargs param, I think there is no need for overloading the log helper method for other consumers than (String, Object[]).

You can use arrows:

arrows(x,y-sd,x,y+sd, code=3, length=0.02, angle = 90)

This will select all rows where some_col is NULL or '' (empty string)

SELECT * FROM table WHERE some_col IS NULL OR some_col = '';

import json

array = '{"fruits": ["apple", "banana", "orange"]}'
data  = json.loads(array)
print data['fruits']
# the print displays:
# [u'apple', u'banana', u'orange']

You had everything you needed. data will be a dict, and data['fruits'] will be a list

As others have said it depends on the encoding of the values in the byte array. Despite this you need to be very careful with this sort of thing or you may try to convert bytes that are not handled by the chosen encoding.

Jon Skeet has a good article about encoding and unicode in .NET. Recommended reading.

Slight improvement to Astander's answer. I like to put my criteria at top, and make it easier to reuse day to day:

In attribute inspector give the identifier for that view controller and the below code works for me

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
DetailViewController *detailViewController = [storyboard instantiateViewControllerWithIdentifier:@"DetailViewController"];
[self.navigationController pushViewController:detailViewController animated:YES];

Driver manager logs can be used to get console logs from browser and it will help to identify errors appears in console.

   import org.openqa.selenium.logging.LogEntries;
   import org.openqa.selenium.logging.LogEntry;

    public List<LogEntry> getBrowserConsoleLogs()
    {
    LogEntries log= driver.manage().logs().get("browser")
    List<LogEntry> logs=log.getAll();
    return logs;
    }

There is no need to use an ObjectIndexer<T>, or change the interface of the original object (like suggested in most of the other answers). You can simply narrow the options for key to the ones that are of type string using the following:

type KeysMatching<T, V> = { [K in keyof T]: T[K] extends V ? K : never }[keyof T];

This great solution comes from an answer to a related question here.

Like that you narrow to keys inside T that hold V values. So in your case to to limit to string you would do:

type KeysMatching<ISomeObject, string>;

In your example:

interface ISomeObject {
    firstKey:   string;
    secondKey:  string;
    thirdKey:   string;
}

let someObject: ISomeObject = {
    firstKey:   'firstValue',
    secondKey:  'secondValue',
    thirdKey:   'thirdValue'
};

let key: KeysMatching<SomeObject, string> = 'secondKey';

// secondValue narrowed to string    
let secondValue = someObject[key];

The advantage is that your ISomeObject could now even hold mixed types, and you can anyway narrow the key to string values only, keys of other value types will be considered invalid. To illustrate:

interface ISomeObject {
    firstKey:   string;
    secondKey:  string;
    thirdKey:   string;
    fourthKey:  boolean;
}

let someObject: ISomeObject = {
    firstKey:   'firstValue',
    secondKey:  'secondValue',
    thirdKey:   'thirdValue'
    fourthKey:   true
};


// Type '"fourthKey"' is not assignable to type 'KeysMatching<ISomeObject, string>'.(2322)
let otherKey: KeysMatching<SomeOtherObject, string> = 'fourthKey';

let fourthValue = someOtherObject[otherKey];

You find this example in this playground.

To call external file you can use :

load ("path\file")

Exemple: if your file.js file is on your "Documents" file (on windows OS), you can type:

load ("C:\users\user_name\Documents\file.js")

IIS_IUSRS group has prominence only if you are using ApplicationPool Identity. Even though you have this group looks empty at run time IIS adds to this group to run a worker process according to microsoft literature.

I wanna Disable an Input Field on a form and when i submit the form the values from the disabled form is not submitted.

Use Case: i am trying to get Lat Lng from Google Map and wanna Display it.. but dont want the user to edit it.

You can use the readonly property in your input field

<input type="text" readonly="readonly" />

You should only have one <system.web> in your Web.Config Configuration File.

<?xml version="1.0"?>
<configuration>
  <system.web>
    <customErrors mode="Off"/>
    <compilation debug="true"/>
    <authentication mode="None"/>
  </system.web>
</configuration>

input type="submit" is the best way to have a submit button in a form. The downside of this is that you cannot put anything other than text as its value. The button element can contain other HTML elements and content.

Try putting type="submit" instead of type="button" in your button element (source).

Pay particular attention however to the following from that page:

If you use the button element in an HTML form, different browsers will submit different values. Internet Explorer will submit the text between the <button> and </button> tags, while other browsers will submit the content of the value attribute. Use the input element to create buttons in an HTML form.

Solution based on @Elnoor answer, but working with multiple file upload form input and without the "fakepath hack":

HTML:

<div class="custom-file">
    <input id="logo" type="file" class="custom-file-input" multiple>
    <label for="logo" class="custom-file-label text-truncate">Choose file...</label>
</div>

JS:

$('input[type="file"]').on('change', function () {
    let filenames = [];
    let files = document.getElementById('health_claim_file_form_files').files;

    for (let i in files) {
        if (files.hasOwnProperty(i)) {
            filenames.push(files[i].name);
        }
    }

    $(this).next('.custom-file-label').addClass("selected").html(filenames.join(',    '));
});

To produce the output in your comment to your post, this will do it:

use strict;
use warnings;

my @other_array = (0,0,0,1,2,2,3,3,3,4);
my @array;
my %uniqs;

$uniqs{$_}++ for @other_array;

foreach (keys %uniqs) { $array[$_]=$uniqs{$_} }

print "array[$_] = $array[$_]\n" for (0..$#array);

Output:

   array[0] = 3
   array[1] = 1
   array[2] = 2
   array[3] = 3
   array[4] = 1

This is different than your stated algorithm of producing a parallel array with zero values, but it is a more Perly way of doing it...

If you must have a parallel array that is the same size as your first array with the elements initialized to 0, this statement will dynamically do it: @array=(0) x scalar(@other_array); but really, you don't need to do that.

In Python 3, map returns an iterable object of type map, and not a subscriptible list, which would allow you to write map[i]. To force a list result, write

payIntList = list(map(int,payList))

However, in many cases, you can write out your code way nicer by not using indices. For example, with list comprehensions:

payIntList = [pi + 1000 for pi in payList]
for pi in payIntList:
    print(pi)

if you want to use only arraylist then I am worried there is no better way which will create a huge performance benefit. But by only using arraylist i would check before adding into the list like following

void addToList(String s){
  if(!yourList.contains(s))
       yourList.add(s);
}

In this cases using a Set is suitable.

Sine you've mentioned you're using Eclipse... Eclipse can create the JARs for you, so long as you've run each class that has a main once. Right-click the project and click Export, then select "Runnable JAR file" under the Java folder. Select the class name in the launch configuration, choose a place to save the jar, and make a decision how to handle libraries if necessary. Click finish, wipe hands on pants.

or //div[@id='id-74385'][@class='guest clearfix']

After you initialize your MediaPlayer and SeekBar, you can do this :

 Timer timer = new Timer();
    timer.scheduleAtFixedRate(new TimerTask() {
        @Override
        public void run() {
            mSeekBar.setProgress(mMediaPlayer.getCurrentPosition());
        }
    },0,1000);

This updates SeekBar every second(1000ms)

And for updating MediaPlayer, if user drag SeekBar, you must add OnSeekBarChangeListener to your SeekBar :

mSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        @Override
        public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
            mMediaPlayer.seekTo(i);
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }
    });

If you're ready for the 4.0 .NET Framework, there's a new Enum.TryParse() function that's very useful and plays well with the [Flags] attribute. See Enum.TryParse Method (String, TEnum%)

Upgrade Automapper to version 6.2.2. It helped me

Now in ES6 you can create lazy cached properties. On first use the property evaluates once to become a normal static property. Result: The second time the math function overhead is skipped.

The magic is in the getter.

const foo = {
    a: 5,
    b: 6,
    get c() {
        delete this.c;
        return this.c = this.a + this.b
    }
};

In the arrow getter this picks up the surrounding lexical scope.

foo     // {a: 5, b: 6}
foo.c   // 11
foo     // {a: 5, b: 6 , c: 11}  

I ran into this same issue when using anchors for an angular bootstrap drop down. The only solution I found that avoided unwanted side effects (ie. the drop down not closing because of using preventDefault()) was to use the following:

If you are using Sass:

$card-column-sizes: (
    xs: 2,
    sm: 3,
    md: 4,
    lg: 5,
);

@each $breakpoint-size, $column-count in $card-column-sizes {
    @include media-breakpoint-up($breakpoint-size) {
      .card-columns {
        column-count: $column-count;
        column-gap: 1.25rem;

        .card {
          display: inline-block;
          width: 100%; // Don't let them exceed the column width
        }
      }
    }
}

You cannot just put in a function to pause Javascript unfortunately.

You have to use setTimeout()

Example:

function startTimer () {
    timer.start();
    setTimeout(stopTimer,5000);
}

function stopTimer () {
    timer.stop();
}

EDIT:

For your user generated countdown, it is just as simple.

HTML:

<input type="number" id="delay" min="1" max="5">

JS:

var delayInSeconds = parseInt(delay.value);
var delayInMilliseconds = delayInSeconds*1000;

function startTimer () {
    timer.start();
    setTimeout(stopTimer,delayInMilliseconds);
}

function stopTimer () {
    timer.stop;
}

Now you simply need to add a trigger for startTimer(), such as onchange.

I saw this problem before, when the (sub)folder I was trying to add had its name begin with "_Something_"

I removed the underscores and it worked. Check to see if your folder has characters which may be causing problems.

Try this:

re.compile(r"^(.+)\n((?:\n.+)+)", re.MULTILINE)

I think your biggest problem is that you're expecting the ^ and $ anchors to match linefeeds, but they don't. In multiline mode, ^ matches the position immediately following a newline and $ matches the position immediately preceding a newline.

Be aware, too, that a newline can consist of a linefeed (\n), a carriage-return (\r), or a carriage-return+linefeed (\r\n). If you aren't certain that your target text uses only linefeeds, you should use this more inclusive version of the regex:

re.compile(r"^(.+)(?:\n|\r\n?)((?:(?:\n|\r\n?).+)+)", re.MULTILINE)

BTW, you don't want to use the DOTALL modifier here; you're relying on the fact that the dot matches everything except newlines.

Actually, the simplest thing (in GNU sed, at least) is to use a different separator for the sed substitution (s) command. So, instead of s/pattern/'$mypath'/ being expanded to s/pattern//my/path/, which will of course confuse the s command, use s!pattern!'$mypath'!, which will be expanded to s!pattern!/my/path!. I’ve used the bang (!) character (or use anything you like) which avoids the usual, but-by-no-means-your-only-choice forward slash as the separator.

I always use DATETIME fields for anything other than row metadata (date created or modified).

As mentioned in the MySQL documentation:

The DATETIME type is used when you need values that contain both date and time information. MySQL retrieves and displays DATETIME values in 'YYYY-MM-DD HH:MM:SS' format. The supported range is '1000-01-01 00:00:00' to '9999-12-31 23:59:59'.

...

The TIMESTAMP data type has a range of '1970-01-01 00:00:01' UTC to '2038-01-09 03:14:07' UTC. It has varying properties, depending on the MySQL version and the SQL mode the server is running in.

You're quite likely to hit the lower limit on TIMESTAMPs in general use -- e.g. storing birthdate.

I benchmarked two approaches for this over 63 bit numbers (the long long type on gcc x86_64), staying away from the sign bit.

(I happen to need this "find highest bit" for something, you see.)

I implemented the data-driven binary search (closely based on one of the above answers). I also implemented a completely unrolled decision tree by hand, which is just code with immediate operands. No loops, no tables.

The decision tree (highest_bit_unrolled) benchmarked to be 69% faster, except for the n = 0 case for which the binary search has an explicit test.

The binary-search's special test for 0 case is only 48% faster than the decision tree, which does not have a special test.

int highest_bit(long long n)
{

  };
  int hi = 64;
  int lo = 0;
  int i = 0;

  if (n == 0)
    return 0;

  for (i = 0; i < sizeof mask / sizeof mask[0]; i++) {
    int mi = lo + (hi - lo) / 2;

    if ((n >> mi) != 0)
      lo = mi;
    else if ((n & (mask[i] << lo)) != 0)
      hi = mi;
  }

  return lo + 1;
}

Quick and dirty test program:

#include <stdio.h>
#include <time.h>
#include <stdlib.h>

int highest_bit_unrolled(long long n);
int highest_bit(long long n);

main(int argc, char **argv)
{
  long long n = strtoull(argv[1], NULL, 0);
  int b1, b2;
  long i;
  clock_t start = clock(), mid, end;

  for (i = 0; i < 1000000000; i++)
    b1 = highest_bit_unrolled(n);

  mid = clock();

  for (i = 0; i < 1000000000; i++)
    b2 = highest_bit(n);

  end = clock();

  printf("highest bit of 0x%llx/%lld = %d, %d\n", n, n, b1, b2);

  printf("time1 = %d\n", (int) (mid - start));
  printf("time2 = %d\n", (int) (end - mid));
  return 0;
}

Using only -O2, the difference becomes greater. The decision tree is almost four times faster.

I also benchmarked against the naive bit shifting code:

int highest_bit_shift(long long n)
{
  int i = 0;
  for (; n; n >>= 1, i++)
    ; /* empty */
  return i;
}

This is only fast for small numbers, as one would expect. In determining that the highest bit is 1 for n == 1, it benchmarked more than 80% faster. However, half of randomly chosen numbers in the 63 bit space have the 63rd bit set!

On the input 0x3FFFFFFFFFFFFFFF, the decision tree version is quite a bit faster than it is on 1, and shows to be 1120% faster (12.2 times) than the bit shifter.

I will also benchmark the decision tree against the GCC builtins, and also try a mixture of inputs rather than repeating against the same number. There may be some sticking branch prediction going on and perhaps some unrealistic caching scenarios which makes it artificially faster on repetitions.

There are a lot of good answers here, but since I independently arrived at my own before reading this, I figured I'd toss mine up here anyway...

Here's a method that I'm using for this which will work universally across compilers and platforms:

Create a struct or class as a container for your collection of objects. Define an operator overload function for <<.

class MyObject;

struct MyObjectList
{
    std::list<MyObject> objects;
    MyObjectList& operator<<( const MyObject o )
    { 
        objects.push_back( o );
        return *this; 
    }
};

You can create functions which take your struct as a parameter, e.g.:

someFunc( MyObjectList &objects );

Then, you can call that function, like this:

someFunc( MyObjectList() << MyObject(1) <<  MyObject(2) <<  MyObject(3) );

That way, you can build and pass a dynamically sized collection of objects to a function in one single clean line!

openFileInput() doesn't accept paths, only a file name if you want to access a path, use File file = new File(path) and corresponding FileInputStream

clang++ 3.5 even warns on it:

/tmp/a.C:3:7: warning: reference cannot be bound to dereferenced null pointer in well-defined C++ code; comparison may be assumed to
      always evaluate to false [-Wtautological-undefined-compare]
if( & nullReference == 0 ) // null reference
      ^~~~~~~~~~~~~    ~

If you are given this format it takes like a link to another page or another link.partial view majorly used for renduring the html files from one place to another.

? .exe and dll are the compiled version of c# code which are also called as assemblies.

? .exe is a stand alone executable file, which means it can executed directly.

? .dll is a reusable component which cannot be executed directly and it requires other programs to execute it.

The 1. usecase which comes into my mind, is an api call, which should't go into the render, because it will run for each state change. And the API call should be only performed on special state change, and not on every render.

changeSearchParams = (params) => {
  this.setState({ params }, this.performSearch)
} 

performSearch = () => {
  API.search(this.state.params, (result) => {
    this.setState({ result })
  });
}

Hence for any state change, an action can be performed in the render methods body.

Very bad practice, because the render-method should be pure, it means no actions, state changes, api calls, should be performed, just composite your view and return it. Actions should be performed on some events only. Render is not an event, but componentDidMount for example.

The closest you say... Let me think... This must be fork() I guess :)

For details see Does Interix implement fork()?

There are 4 main factors into why you would want to use synchronized or java.util.concurrent.Lock.

Note: Synchronized locking is what I mean when I say intrinsic locking.

1. When Java 5 came out with ReentrantLocks, they proved to have quite a noticeble throughput difference then intrinsic locking. If youre looking for faster locking mechanism and are running 1.5 consider j.u.c.ReentrantLock. Java 6's intrinsic locking is now comparable.

2. j.u.c.Lock has different mechanisms for locking. Lock interruptable - attempt to lock until the locking thread is interrupted; timed lock - attempt to lock for a certain amount of time and give up if you do not succeed; tryLock - attempt to lock, if some other thread is holding the lock give up. This all is included aside from the simple lock. Intrinsic locking only offers simple locking

3. Style. If both 1 and 2 do not fall into categories of what you are concerned with most people, including myself, would find the intrinsic locking semenatics easier to read and less verbose then j.u.c.Lock locking.
4. Multiple Conditions. An object you lock on can only be notified and waited for a single case. Lock's newCondition method allows for a single Lock to have mutliple reasons to await or signal. I have yet to actually need this functionality in practice, but is a nice feature for those who need it.

Logging options are provider-specific. You need to know which JPA implementation do you use.

• Hibernate (see here):

  <property name = "hibernate.show_sql" value = "true" />
  

• EclipseLink (see here):

  <property name="eclipselink.logging.level" value="FINE"/>
  

• OpenJPA (see here):

  <property name="openjpa.Log" value="DefaultLevel=WARN,Runtime=INFO,Tool=INFO,SQL=TRACE"/>
  

• DataNucleus (see here):

  Set the log category DataNucleus.Datastore.Native to a level, like DEBUG.

You can increase the capacity of the stack by the following :

import sys
sys.setrecursionlimit(10000)

Add this to your project-level build.gradle file:

repositories {
    maven {
        url "https://maven.google.com"
    }
}

It worked for me

I had this problem on production with Heroku and locally while debugging on my macbook pro this morning.

After an hour of debugging, this resolved on its own both locally and on production. I'm not sure what fixed it, so that's a bit annoying. It happened right when I thought I did something, but reverting my supposed fix didn't bring the problem back :(

Interestingly enough, it appears my database service, MongoDb has been having server problems since this morning, so there's a good chance this was related to it.

If you're using Spring you can simply call HtmlUtils.htmlEscape(String input) which will handle the '&' to '&' translation.

What we ended up doing is stopped using the class components and created Functional Components, using useEffect() from the Hooks API for lifecycle methods. This allows you to still use makeStyles() with Lifecycle Methods without adding the complication of making Higher-Order Components. Which is much simpler.

Example:

import React, { useEffect, useState } from 'react';
import axios from 'axios';
import { Redirect } from 'react-router-dom';

import { Container, makeStyles } from '@material-ui/core';

import LogoButtonCard from '../molecules/Cards/LogoButtonCard';

const useStyles = makeStyles(theme => ({
  root: {
    display: 'flex',
    alignItems: 'center',
    justifyContent: 'center',
    margin: theme.spacing(1)
  },
  highlight: {
    backgroundColor: 'red',
  }
}));

// Highlight is a bool
const Welcome = ({highlight}) => { 
  const [userName, setUserName] = useState('');
  const [isAuthenticated, setIsAuthenticated] = useState(true);
  const classes = useStyles();

  useEffect(() => {
    axios.get('example.com/api/username/12')
         .then(res => setUserName(res.userName));
  }, []);

  if (!isAuthenticated()) {
    return <Redirect to="/" />;
  }
  return (
    <Container maxWidth={false} className={highlight ? classes.highlight : classes.root}>
      <LogoButtonCard
        buttonText="Enter"
        headerText={isAuthenticated && `Welcome, ${userName}`}
        buttonAction={login}
      />
   </Container>
   );
  }
}

export default Welcome;

The problem is that you are using getSystemResourceAsStream. Use simply getResourceAsStream. System resources load from the system classloader, which is almost certainly not the class loader that your jar is loaded into when run as a webapp.

It works in Eclipse because when launching an application, the system classloader is configured with your jar as part of its classpath. (E.g. java -jar my.jar will load my.jar in the system class loader.) This is not the case with web applications - application servers use complex class loading to isolate webapplications from each other and from the internals of the application server. For example, see the tomcat classloader how-to, and the diagram of the classloader hierarchy used.

EDIT: Normally, you would call getClass().getResourceAsStream() to retrieve a resource in the classpath, but as you are fetching the resource in a static initializer, you will need to explicitly name a class that is in the classloader you want to load from. The simplest approach is to use the class containing the static initializer, e.g.

[public] class MyClass {
  static
  {
    ...
    props.load(MyClass.class.getResourceAsStream("/someProps.properties"));
  }
}

Just right click the Project -- Properties and select Resource on the left side menu.

You can now change the Text-file encoding to whatever you wish.

Convert CString to string (VC6)

I have tested this and it works fine.

std::string Utils::CString2String(const CString& cString) 
{
    std::string strStd;

    for (int i = 0;  i < cString.GetLength();  ++i)
    {
        if (cString[i] <= 0x7f)
            strStd.append(1, static_cast<char>(cString[i]));
        else
            strStd.append(1, '?');
    }

    return strStd;
}

You missed some breaks there:

switch (searchType)
{
    case "SearchBooks":
        Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
        Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
        break;

    case "SearchAuthors":
        Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
        Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
        break;
}

Without them, the compiler thinks you're trying to execute the lines below case "SearchAuthors": immediately after the lines under case "SearchBooks": have been executed, which isn't allowed in C#.

By adding the break statements at the end of each case, the program exits each case after it's done, for whichever value of searchType.

I use this one to run a shell script on a remote machine (tested on /bin/bash):

ssh deploy@host . /home/deploy/path/to/script.sh

Error checking and handling is the programmer's friend. Check the return values of the initializing and executing cURL functions. curl_error() and curl_errno() will contain further information in case of failure:

try {
    $ch = curl_init();

    // Check if initialization had gone wrong*    
    if ($ch === false) {
        throw new Exception('failed to initialize');
    }

    curl_setopt($ch, CURLOPT_URL, 'http://example.com/');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt(/* ... */);

    $content = curl_exec($ch);

    // Check the return value of curl_exec(), too
    if ($content === false) {
        throw new Exception(curl_error($ch), curl_errno($ch));
    }

    /* Process $content here */

    // Close curl handle
    curl_close($ch);
} catch(Exception $e) {

    trigger_error(sprintf(
        'Curl failed with error #%d: %s',
        $e->getCode(), $e->getMessage()),
        E_USER_ERROR);

}

^* The curl_init() manual states:

Returns a cURL handle on success, FALSE on errors.

I've observed the function to return FALSE when you're using its $url parameter and the domain could not be resolved. If the parameter is unused, the function might never return FALSE. Always check it anyways, though, since the manual doesn't clearly state what "errors" actually are.

I went through the Android Device Monitor

1. Click on device
2. Select Android Device Monitor's File Explorer tab
3. Select Pictures folder (path: data -> media -> 0 -> Pictures)
4. Click "Push folders on to device" icon
5. Select pic from computer and ok.

Use this style to change only the nested lists:

ol ol > li:before {

}

Here s what I suggest without using any other dependency , just node and express, use app.locals, here s an example :

    app.get("/", function(req, res) {
        var context = req.app.locals.specialContext;
        req.app.locals.specialContext = null;
        res.render("home.jade", context); 
        // or if you are using ejs
        res.render("home", {context: context}); 
    });

    function middleware(req, res, next) {
        req.app.locals.specialContext = * your context goes here *
        res.redirect("/");
    }

In a latest Jenkins (1.639 and above) you can:

1. just specify name of tag in a field 'Branches to build'.
2. in a parametrized build you can use parameter as variable in a same field 'Branches to build' i.e. ${Branch_to_build}.
3. you can install Git Parameter Plugin which will provide to you functionality by listing of all available branches and tags.

I am not writing anything same here. Just a changelog note from PHP manual.

Changelog for continue

Version Description

7.0.0 - continue outside of a loop or switch control structure is now detected at compile-time instead of run-time as before, and triggers an E_COMPILE_ERROR.

5.4.0   continue 0; is no longer valid. In previous versions it was interpreted the same as continue 1;.

5.4.0   Removed the ability to pass in variables (e.g., $num = 2; continue $num;) as the numerical argument.

Changelog for break

Version Description

7.0.0   break outside of a loop or switch control structure is now detected at compile-time instead of run-time as before, and triggers an E_COMPILE_ERROR.

5.4.0   break 0; is no longer valid. In previous versions it was interpreted the same as break 1;.

5.4.0   Removed the ability to pass in variables (e.g., $num = 2; break $num;) as the numerical argument.

I had the same problem (with a version of git-recent) and discovered it was to do with color escape codes used by git. I wonder whether this could explain why this problem is occurring so commonly.

This is demonstrates what could be happening, though color is normally set in git configuration rather than the command line (otherwise it's effect would be obvious):

~/dev/trunk (master)$ git checkout `git branch -l  --color=always  | grep django-1.11`
error: pathspec 'django-1.11' did not match any file(s) known to git.
~/dev/trunk (master)$ git branch -l  --color=always  | grep django-1.11
  django-1.11
~/dev/trunk (master)$ git checkout `git branch -l  | grep django-1.11`
Switched to branch 'django-1.11'
Your branch is up-to-date with 'gerrit/django-1.11'.
~/dev/trunk (django-1.11)$ 

I figure a git config that doesn't play with the color settings should work color=auto should do the right thing. My particular issue was because the git recent I was using was defined as an alias with hard coded colors, and I was trying to build commands on top of that

It's between the Z and the C on your keyboard.

I think you have an issue with your server certificate, is not a valid certificate (I think this is what "handshake_failure" means in this case):

Import your server certificate into your trustcacerts keystore on client's JRE. This is easily done with keytool:

keytool
    -import
    -alias <provide_an_alias>
    -file <certificate_file>
    -keystore <your_path_to_jre>/lib/security/cacerts

class Outer(object):
    outer_var = 1

    class Inner(object):
        @property
        def inner_var(self):
            return Outer.outer_var

This isn't quite the same as similar things work in other languages, and uses global lookup instead of scoping the access to outer_var. (If you change what object the name Outer is bound to, then this code will use that object the next time it is executed.)

If you instead want all Inner objects to have a reference to an Outer because outer_var is really an instance attribute:

class Outer(object):
    def __init__(self):
        self.outer_var = 1

    def get_inner(self):
        return self.Inner(self)
        # "self.Inner" is because Inner is a class attribute of this class
        # "Outer.Inner" would also work, or move Inner to global scope
        # and then just use "Inner"

    class Inner(object):
        def __init__(self, outer):
            self.outer = outer

        @property
        def inner_var(self):
            return self.outer.outer_var

Note that nesting classes is somewhat uncommon in Python, and doesn't automatically imply any sort of special relationship between the classes. You're better off not nesting. (You can still set a class attribute on Outer to Inner, if you want.)

They are all the same in the work they do. You can do the same things using any of them. But for readability, usability, convenience etc., they differ.

window.location = mypage.href is a direct command for the browser to dump it's contents and start loading up some more. So for better clarification, here's what's happening in your PHP script:

echo '<script type="text/javascript">'; 
echo 'alert("review your answer");'; 
echo 'window.location = "index.php";';
echo '</script>';

1) prepare to accept a modification or addition to the current Javascript cache. 2) show the alert 3) dump everything in browser memory and get ready for some more (albeit an older method of loading a new URL (AND NOTICE that there are no "\n" (new line) indicators between the lines and is therefore causing some havoc in the JS decoder.

Let me suggest that you do this another way..

echo '<script type="text/javascript">\n'; 
echo 'alert("review your answer");\n'; 
echo 'document.location.href = "index.php";\n';
echo '</script>\n';

1) prepare to accept a modification or addition to the current Javascript cache. 2) show the alert 3) dump everything in browser memory and get ready for some more (in a better fashion than before) And WOW - it all works because the JS decoder can see that each command is anow a new line.

Best of luck!

Simply:

x <- vector(mode="numeric", length=0)

Here there are two issues we have to concentrate on:

1. HAX device failed to open,

   For this problem, you have to run the HAX device setup file from the HAX addon folder. Follow Speed Up Android Emulator to know clearly how.

2. If you created the AVD through AVD manager then you can change the RAM size in AVD Manager and device edit option.

If you created the AVD through command line, then you should start the AVD from command line will work,

emulator -memory 512 -avd gtv_avd

The way that the language manages lexical scope creates issues with including both goto and continue. For example,

local a=0
repeat 
    if f() then
        a=1 --change outer a
    end
    local a=f() -- inner a
until a==0 -- test inner a

The declaration of local a inside the loop body masks the outer variable named a, and the scope of that local extends across the condition of the until statement so the condition is testing the innermost a.

If continue existed, it would have to be restricted semantically to be only valid after all of the variables used in the condition have come into scope. This is a difficult condition to document to the user and enforce in the compiler. Various proposals around this issue have been discussed, including the simple answer of disallowing continue with the repeat ... until style of loop. So far, none have had a sufficiently compelling use case to get them included in the language.

The work around is generally to invert the condition that would cause a continue to be executed, and collect the rest of the loop body under that condition. So, the following loop

-- not valid Lua 5.1 (or 5.2)
for k,v in pairs(t) do
  if isstring(k) then continue end
  -- do something to t[k] when k is not a string
end

could be written

-- valid Lua 5.1 (or 5.2)
for k,v in pairs(t) do
  if not isstring(k) then 
    -- do something to t[k] when k is not a string
  end
end

It is clear enough, and usually not a burden unless you have a series of elaborate culls that control the loop operation.

Q1) Here are couple things to read or google more :

Main differences between SOAP and RESTful web services in java http://www.ajaxonomy.com/2008/xml/web-services-part-1-soap-vs-rest

It's up to you what do you want to learn first. I'd recommend you take a look at the CXF framework. You can build both rest/soap services.

Q2) Here are couple of good tutorials for soap (I had them bookmarked) :

http://united-coders.com/phillip-steffensen/developing-a-simple-soap-webservice-using-spring-301-and-apache-cxf-226

http://www.benmccann.com/blog/web-services-tutorial-with-apache-cxf/

http://www.mastertheboss.com/web-interfaces/337-apache-cxf-interceptors.html

Best way to learn is not just reading tutorials. But you would first go trough tutorials to get a basic idea so you can see that you're able to produce something(or not) and that would get you motivated.

SO is great way to learn particular technology (or more), people ask lot of wierd questions, and there are ever weirder answers. But overall you'll learn about ways to solve issues on other way. Maybe you didn't know of that way, maybe you couldn't thought of it by yourself.

Subscribe to couple of tags that are interesting to you and be persistent, ask good questions and try to give good answers and I guarantee you that you'll learn this as time passes (if you're persistent that is).

Q3) You will have to answer this one yourself. First by deciding what you're going to build, after all you will need to think of some mini project or something and take it from there.

If you decide to use CXF as your framework for building either REST/SOAP services I'd recommend you look up this book Apache CXF Web Service Development. It's fantastic, not hard to read and not too big either (win win).

you can try

"str".charCodeAt(0)

You have Numpy Data Type, Just change to normal int() or float() data type. it will work fine.

Let's say you want to pass a prop to a child component and that prop is a boolean that will determine if the checkbox is checked or not, then you have to pass the boolean value to the v-bind:checked="booleanValue" or the shorter way :checked="booleanValue", for example:

<input
    id="checkbox"
    type="checkbox"
    :value="checkboxVal"
    :checked="booleanValue"
    v-on:input="checkboxVal = $event.target.value"
/>

That should work and the checkbox will display the checkbox with it's current boolean state (if true checked, if not unchecked).

Not unless you make all variables "public", i.e. make them members of the Function either directly or through the prototype property.

var C = function( ) {
    this.x = 10 , this.y = 20 ;
    this.modify = function( ) {
        this.x = 30 , this.y = 40 ;
        console.log("(!) C >> " + (this.x + this.y) ) ;
    } ;
} ;

var A = function( ) {
    this.modify = function( ) {
       this.x = 300 , this.y = 400 ;
       console.log("(!) A >> " + (this.x + this.y) ) ;
    } ;
} ;
    A.prototype = new C ;

var B = function( ) {
    this.modify = function( ) {
       this.x = 3000 , this.y = 4000 ;
       console.log("(!) B >> " + (this.x + this.y) ) ;
    } ;
} ;


new C( ).modify( ) ;
new A( ).modify( ) ;
new B( ).modify( ) ; 

• test it here

You will notice a few changes.

Most importantly the call to the supposed "super-classes" constructor is now implicit within this line:

<name>.prototype = new C ;

Both A and B will now have individually modifiable members x and y which would not be the case if we would have written ... = C instead.

Then, x, y and modify are all "public" members so that assigning a different Function to them

 <name>.prototype.modify = function( ) { /* ... */ }

will "override" the original Function by that name.

Lastly, the call to modify cannot be done in the Function declaration because the implicit call to the "super-class" would then be executed again when we set the supposed "super-class" to the prototype property of the supposed "sub-classes".

But well, this is more or less how you would do this kind of thing in JavaScript.

HTH,

FK

You could use a "variable" inside the output filename, for example:

/tmp/FetchBlock-${current_date}.txt

current_date:

Returns the current system time formatted as yyyyMMdd_HHmm. An optional argument can be used to provide alternative formatting. The argument must be valid pattern for java.util.SimpleDateFormat.

Or you can also use a system_property or an env_var to specify something dynamic (either one needs to be specified as arguments)

If you don't call the favicon, favicon.ico, you can use that tag to specify the actual path (incase you have it in an images/ directory). The browser/webpage looks for favicon.ico in the root directory by default.

thisTag = _tags.FirstOrDefault(t => t.Key == tag);

is an inefficient and a little bit strange way to find something by key in a dictionary. Looking things up for a Key is the basic function of a Dictionary.

The basic solution would be:

if (_tags.Containskey(tag)) { string myValue = _tags[tag]; ... }

But that requires 2 lookups.

TryGetValue(key, out value) is more concise and efficient, it only does 1 lookup. And that answers the last part of your question, the best way to do a lookup is:

string myValue;
if (_tags.TryGetValue(tag, out myValue)) { /* use myValue */ }

VS 2017 update, for C# 7 and beyond we can declare the result variable inline:

if (_tags.TryGetValue(tag, out string myValue))
{
    // use myValue;
}
// use myValue, still in scope, null if not found

$result = mysql_query($query) or die("Data not found."); 
$rows=array(); 
while($r=mysql_fetch_assoc($result))
{ 
$rows[]=$r;
}
header("Content-type:application/json"); 
echo json_encode($rows);

To understand this peculiar behavior of hibernate, it is important to understand a few hibernate concepts -

Hibernate Object States

Transient - An object is in transient status if it has been instantiated and is still not associated with a Hibernate session.

Persistent - A persistent instance has a representation in the database and an identifier value. It might just have been saved or loaded, however, it is by definition in the scope of a Session.

Detached - A detached instance is an object that has been persistent, but its Session has been closed.

http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/objectstate.html#objectstate-overview

Transaction Write-Behind

The next thing to understand is 'Transaction Write behind'. When objects attached to a hibernate session are modified they are not immediately propagated to the database. Hibernate does this for at least two different reasons.

• To perform batch inserts and updates.
• To propagate only the last change. If an object is updated more than once, it still fires only one update statement.

http://learningviacode.blogspot.com/2012/02/write-behind-technique-in-hibernate.html

First Level Cache

Hibernate has something called 'First Level Cache'. Whenever you pass an object to save(), update() or saveOrUpdate(), and whenever you retrieve an object using load(), get(), list(), iterate() or scroll(), that object is added to the internal cache of the Session. This is where it tracks changes to various objects.

Hibernate Intercepters and Object Lifecycle Listeners -

The Interceptor interface and listener callbacks from the session to the application, allow the application to inspect and/or manipulate properties of a persistent object before it is saved, updated, deleted or loaded. http://docs.jboss.org/hibernate/orm/4.0/hem/en-US/html/listeners.html#d0e3069

This section Updated

Cascading

Hibernate allows applications to define cascade relationships between associations. For example, 'cascade-delete' from parent to child association will result in deletion of all children when a parent is deleted.

So, why are these important.

To be able to do transaction write-behind, to be able to track multiple changes to objects (object graphs) and to be able to execute lifecycle callbacks hibernate needs to know whether the object is transient/detached and it needs to have the object in it's first level cache before it makes any changes to the underlying object and associated relationships.

That's why hibernate (sometimes) issues a 'SELECT' statement to load the object (if it's not already loaded) in to it's first level cache before it makes changes to it.

Why does hibernate issue the 'SELECT' statement only sometimes?

Hibernate issues a 'SELECT' statement to determine what state the object is in. If the select statement returns an object, the object is in detached state and if it does not return an object, the object is in transient state.

Coming to your scenario -

Delete - The 'Delete' issued a SELECT statement because hibernate needs to know if the object exists in the database or not. If the object exists in the database, hibernate considers it as detached and then re-attches it to the session and processes delete lifecycle.

Update - Since you are explicitly calling 'Update' instead of 'SaveOrUpdate', hibernate blindly assumes that the object is in detached state, re-attaches the given object to the session first level cache and processes the update lifecycle. If it turns out that the object does not exist in the database contrary to hibernate's assumption, an exception is thrown when session flushes.

SaveOrUpdate - If you call 'SaveOrUpdate', hibernate has to determine the state of the object, so it uses a SELECT statement to determine if the object is in Transient/Detached state. If the object is in transient state, it processes the 'insert' lifecycle and if the object is in detached state, it processes the 'Update' lifecycle.

If you don't want to use the libraries and want simple answer then the code is given below:

  def swap_alpha(test_string):
      new_string = ""
      for i in test_string:
          if i.upper() in test_string:
              new_string += i.lower()

          elif i.lower():
                new_string += i.upper()

          else:
              return "invalid "

      return new_string


user_string = input("enter the string:")
updated = swap_alpha(user_string)
print(updated)

No-one has mentioned cpio which is easy to type, creates hard links and handles spaces in filenames:

git diff --name-only $from..$to  | cpio -pld outdir

integrity - defines the hash value of a resource (like a checksum) that has to be matched to make the browser execute it. The hash ensures that the file was unmodified and contains expected data. This way browser will not load different (e.g. malicious) resources. Imagine a situation in which your JavaScript files were hacked on the CDN, and there was no way of knowing it. The integrity attribute prevents loading content that does not match.

Invalid SRI will be blocked (Chrome developer-tools), regardless of cross-origin. Below NON-CORS case when integrity attribute does not match:

Integrity can be calculated using: https://www.srihash.org/ Or typing into console (link):

openssl dgst -sha384 -binary FILENAME.js | openssl base64 -A

crossorigin - defines options used when the resource is loaded from a server on a different origin. (See CORS (Cross-Origin Resource Sharing) here: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS). It effectively changes HTTP requests sent by the browser. If the “crossorigin” attribute is added - it will result in adding origin: <ORIGIN> key-value pair into HTTP request as shown below.

crossorigin can be set to either “anonymous” or “use-credentials”. Both will result in adding origin: into the request. The latter however will ensure that credentials are checked. No crossorigin attribute in the tag will result in sending a request without origin: key-value pair.

Here is a case when requesting “use-credentials” from CDN:

<script 
        src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/js/bootstrap.min.js"
        integrity="sha384-vBWWzlZJ8ea9aCX4pEW3rVHjgjt7zpkNpZk+02D9phzyeVkE+jo0ieGizqPLForn" 
        crossorigin="use-credentials"></script>

A browser can cancel the request if crossorigin incorrectly set.

Maybe it helps someone who comes across the question: All the Conditional Renderings in React It's an article about all the different options for conditional rendering in React.

Key takeaways of when to use which conditional rendering:

** if-else

• is the most basic conditional rendering
• beginner friendly
• use if to opt-out early from a render method by returning null

** ternary operator

• use it over an if-else statement
• it is more concise than if-else

** logical && operator

• use it when one side of the ternary operation would return null

** switch case

• verbose
• can only be inlined with self invoking function
• avoid it, use enums instead

** enums

• perfect to map different states
• perfect to map more than one condition

** multi-level/nested conditional renderings

• avoid them for the sake of readability
• split up components into more lightweight components with their own simple conditional rendering
• use HOCs

** HOCs

• use them to shield away conditional rendering
• components can focus on their main purpose

** external templating components

• avoid them and be comfortable with JSX and JavaScript

If none of this did not help, then try to swap ^ in "^version" to ~ "~version".

Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.

From Git documentation starting from version 2.0:

To add content for the whole tree, run:

git add --all :/

or

git add -A :/

To restrict the command to the current directory, run:

git add --all .

or

git add -A .

This option comes in curl 7.73.0:

curl --create-dirs -O --output-dir /tmp/receipes https://example.com/pancakes.jpg

In your configurations, specify the port number your database is on. You can find the port number at the top left corner of phpMyAdmin. It would look something like this

const DB_HOST = 'localhost:3308';

Same @regular 's accepted solution, but Fish shell flavour

if not contains (npm bin) $PATH
    set PATH (npm bin) $PATH
end

What's the first part of your Subversion repository URL?

• If your URL looks like: http://subversion/repos/, then you're probably going over Port 80.
• If your URL looks like: https://subversion/repos/, then you're probably going over Port 443.
• If your URL looks like: svn://subversion/, then you're probably going over Port 3690.
• If your URL looks like: svn+ssh://subversion/repos/, then you're probably going over Port 22.
• If your URL contains a port number like: http://subversion/repos:8080, then you're using that port.

I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.

If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.

The only way around that is to log into a local machine over the VPN, and then do everything from that system.

in spring boot project we can write logging.level.root=WARN but here problem is, we have to restart again even we added devtools dependency, in property file if we are modified any value will not autodetectable, for this limitation i came to know the solution i,e we can add actuator in pom.xml and pass the logger level as below shown in postman client in url bar http://localhost:8080/loggers/ROOT or http://localhost:8080/loggers/com.mycompany and in the body you can pass the json format like below

{
  "configuredLevel": "WARN"
}

Since you're looking for the ability to shoehorn binary data into a strictly text-based and very limited format, I think Base64's overhead is minimal compared to the convenience you're expecting to maintain with JSON. If processing power and throughput is a concern, then you'd probably need to reconsider your file formats.

Use strstr(const char *s , const char *t) and include<string.h>

You can write your own function which behaves same as strstr and you can modify according to your requirement also

char * str_str(const char *s, const char *t)
{
int i, j, k;
for (i = 0; s[i] != '\0'; i++) 
{
for (j=i, k=0; t[k]!='\0' && s[j]==t[k]; j++, k++);
if (k > 0 && t[k] == '\0')
return (&s[i]);
}
return NULL;
}

I assume this was added to Windows cmd.exe at some point.

Maven or Ant? is a very similar question to this one, which should help you answer your questions.

What is Maven? on the official site.

edit: For a new/greenfield project, I'd recommend using Maven: "convention over configuration" will save you a decent chunk of time in writing and setting up build and deployment scripts. When you use ant, the build script tends to grow over time in length and complexity. For existing projects, it can be hard to shoehorn their configuration/layout into the Maven system.

You can use cut:

cut -c N- file.txt > new_file.txt

-c: characters

file.txt: input file

new_file.txt: output file

N-: Characters from N to end to be cut and output to the new file.

Can also have other args like: 'N' , 'N-M', '-M' meaning nth character, nth to mth character, first to mth character respectively.

This will perform the operation to each line of the input file.

Since SensorListener is deprecated so use the following code:

/* put this into your activity class */
private SensorManager mSensorManager;
private float mAccel; // acceleration apart from gravity
private float mAccelCurrent; // current acceleration including gravity
private float mAccelLast; // last acceleration including gravity

private final SensorEventListener mSensorListener = new SensorEventListener() {

  public void onSensorChanged(SensorEvent se) {
    float x = se.values[0];
    float y = se.values[1];
    float z = se.values[2];
    mAccelLast = mAccelCurrent;
    mAccelCurrent = (float) Math.sqrt((double) (x*x + y*y + z*z));
    float delta = mAccelCurrent - mAccelLast;
    mAccel = mAccel * 0.9f + delta; // perform low-cut filter
  }

  public void onAccuracyChanged(Sensor sensor, int accuracy) {
  }
};

@Override
protected void onResume() {
  super.onResume();
  mSensorManager.registerListener(mSensorListener, mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
}

@Override
protected void onPause() {
  mSensorManager.unregisterListener(mSensorListener);
  super.onPause();
}

Then:

/* do this in onCreate */
mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
mSensorManager.registerListener(mSensorListener, mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
mAccel = 0.00f;
mAccelCurrent = SensorManager.GRAVITY_EARTH;
mAccelLast = SensorManager.GRAVITY_EARTH;

Android: I want to shake it

My answer comes quite late because I'm a pretty new developer. This is what you can do:

Location.select(:name, :website, :city).find(row.id)

Btw, this is Rails 4

1.THE USE OF {}:

It initialize the array with the values { }

2.The difference between String array=new String[]; and String array=new String[]{};

String array=new String[]; and String array=new String[]{}; both are invalid statement in java.

It will gives you an error that you are trying to assign String array to String datatype. More specifically error is like this Type mismatch: cannot convert from String[] to String

3.String array=new String[10]{}; got error why?

Wrong because you are defining an array of length 10 ([10]), then defining an array of length String[10]{} 0

I think the first way (multiple variables) is best, as you can otherwise end up with this (from an application that uses KnockoutJS), which is difficult to read in my opinion:

    var categories = ko.observableArray(),
        keywordFilter = ko.observableArray(),
        omniFilter = ko.observable('').extend({ throttle: 300 }),
        filteredCategories = ko.computed(function () {
            var underlyingArray = categories();
            return ko.utils.arrayFilter(underlyingArray, function (n) {
                return n.FilteredSportCount() > 0;
            });
        }),
        favoriteSports = ko.computed(function () {
            var sports = ko.observableArray();
            ko.utils.arrayForEach(categories(), function (c) {
                ko.utils.arrayForEach(c.Sports(), function (a) {
                    if (a.IsFavorite()) {
                        sports.push(a);
                    }
                });
            });
            return sports;
        }),
        toggleFavorite = function (sport, userId) {
            var isFavorite = sport.IsFavorite();

            var url = setfavouritesurl;

            var data = {
                userId: userId,
                sportId: sport.Id(),
                isFavourite: !isFavorite
            };

            var callback = function () {
                sport.IsFavorite(!isFavorite);
            };

            jQuery.support.cors = true;
            jQuery.ajax({
                url: url,
                type: "GET",
                data: data,
                success: callback
            });
        },
        hasfavoriteSports = ko.computed(function () {
            var result = false;
            ko.utils.arrayForEach(categories(), function (c) {
                ko.utils.arrayForEach(c.Sports(), function (a) {
                    if (a.IsFavorite()) {
                        result = true;
                    }
                });
            });
            return result;
        });

Try to fill only the HTTP schema

It appears you're missing an important point here: JavaScript is a single-threaded execution environment. Let's look again at your code, note I've added alert("Here"):

var isPaused = false;

function firstFunction(){
    isPaused = true;
    for(i=0;i<x;i++){
        // do something
    }
    isPaused = false;
};

function secondFunction(){
    firstFunction()

    alert("Here");

    function waitForIt(){
        if (isPaused) {
            setTimeout(function(){waitForIt()},100);
        } else {
            // go do that thing
        };
    }
};

You don't have to wait for isPaused. When you see the "Here" alert, isPaused will be false already, and firstFunction will have returned. That's because you cannot "yield" from inside the for loop (// do something), the loop may not be interrupted and will have to fully complete first (more details: Javascript thread-handling and race-conditions).

That said, you still can make the code flow inside firstFunction to be asynchronous and use either callback or promise to notify the caller. You'd have to give up upon for loop and simulate it with if instead (JSFiddle):

function firstFunction()
{
    var deferred = $.Deferred();

    var i = 0;
    var nextStep = function() {
        if (i<10) {
            // Do something
            printOutput("Step: " + i);
            i++;
            setTimeout(nextStep, 500); 
        }
        else {
            deferred.resolve(i);
        }
    }
    nextStep();
    return deferred.promise();
}

function secondFunction()
{
    var promise = firstFunction();
    promise.then(function(result) { 
        printOutput("Result: " + result);
    });
}

On a side note, JavaScript 1.7 has introduced yield keyword as a part of generators. That will allow to "punch" asynchronous holes in otherwise synchronous JavaScript code flow (more details and an example). However, the browser support for generators is currently limited to Firefox and Chrome, AFAIK.

Change the Aux.js to another name, like Sig.js.

The source tree still shows it as a binary file, but you can stage(add) it and commit.

Calculate the difference between latest date in column A with the date in cell A2.

The USAGE-privilege in mysql simply means that there are no privileges for the user 'phpadmin'@'localhost' defined on global level *.*. Additionally the same user has ALL-privilege on database phpmyadmin phpadmin.*.

So if you want to remove all the privileges and start totally from scratch do the following:

• Revoke all privileges on database level:

  REVOKE ALL PRIVILEGES ON phpmyadmin.* FROM 'phpmyadmin'@'localhost';

• Drop the user 'phpmyadmin'@'localhost'

  DROP USER 'phpmyadmin'@'localhost';

Above procedure will entirely remove the user from your instance, this means you can recreate him from scratch.

To give you a bit background on what described above: as soon as you create a user the mysql.user table will be populated. If you look on a record in it, you will see the user and all privileges set to 'N'. If you do a show grants for 'phpmyadmin'@'localhost'; you will see, the allready familliar, output above. Simply translated to "no privileges on global level for the user". Now your grant ALL to this user on database level, this will be stored in the table mysql.db. If you do a SELECT * FROM mysql.db WHERE db = 'nameofdb'; you will see a 'Y' on every priv.

Above described shows the scenario you have on your db at the present. So having a user that only has USAGE privilege means, that this user can connect, but besides of SHOW GLOBAL VARIABLES; SHOW GLOBAL STATUS; he has no other privileges.

I think you should make a subquery to do grouping. In this case inner subquery returns few rows and you don't need a CASE statement. So I think this is going to be faster:

select Detail.ReceiptDate AS 'DATE',
       SUM(TotalMailed),
       SUM(TotalReturnMail),
       SUM(TraceReturnedMail)

from
(

select SentDate AS 'ReceiptDate', 
       count('TotalMailed') AS TotalMailed, 
       0 as TotalReturnMail, 
       0 as TraceReturnedMail
from MailDataExtract
where sentdate is not null
GROUP BY SentDate

UNION ALL
select MDE.ReturnMailDate AS 'ReceiptDate', 
       0 AS TotalMailed, 
       count(TotalReturnMail) as TotalReturnMail, 
       0 as TraceReturnedMail
from MailDataExtract MDE
where MDE.ReturnMailDate is not null
GROUP BY  MDE.ReturnMailDate

UNION ALL

select MDE.ReturnMailDate AS 'ReceiptDate', 
       0 AS TotalMailed, 
       0 as TotalReturnMail, 
       count(TraceReturnedMail) as TraceReturnedMail

from MailDataExtract MDE
    inner join DTSharedData.dbo.ScanData SD 
        ON SD.ScanDataID = MDE.ReturnScanDataID
   where MDE.ReturnMailDate is not null AND SD.ReturnMailTypeID = 1
GROUP BY MDE.ReturnMailDate

) as Detail
GROUP BY Detail.ReceiptDate
ORDER BY 1

You want to apply a custom formatting rule. The "Applies to" field should be your entire row (If you want to format row 5, put in =$5:$5. The custom formula should be =IF($B$5="X", TRUE, FALSE), shown in the example below.

You should use & / | operators and be careful about operator precedence (== has lower precedence than bitwise AND and OR):

df1 = sqlContext.createDataFrame(
    [(1, "a", 2.0), (2, "b", 3.0), (3, "c", 3.0)],
    ("x1", "x2", "x3"))

df2 = sqlContext.createDataFrame(
    [(1, "f", -1.0), (2, "b", 0.0)], ("x1", "x2", "x3"))

df = df1.join(df2, (df1.x1 == df2.x1) & (df1.x2 == df2.x2))
df.show()

## +---+---+---+---+---+---+
## | x1| x2| x3| x1| x2| x3|
## +---+---+---+---+---+---+
## |  2|  b|3.0|  2|  b|0.0|
## +---+---+---+---+---+---+

You can use virtualenv --clear. which won't install any packages, then install the ones you want.

In my view the perfect answer you must required is

var reader = new FileReader();

//Read the contents of Image File.
reader.readAsDataURL(fileUpload.files[0]);
reader.onload = function (e) {

  //Initiate the JavaScript Image object.
  var image = new Image();

  //Set the Base64 string return from FileReader as source.
  image.src = e.target.result;

  //Validate the File Height and Width.
  image.onload = function () {
    var height = this.height;
    var width = this.width;
    if (height > 100 || width > 100) {
      alert("Height and Width must not exceed 100px.");
      return false;
    }
    alert("Uploaded image has valid Height and Width.");
    return true;
  };
};

Here's possibly the simplest way:

IO.copy_stream(URI.open("https://i.pinimg.com/originals/24/17/d6/2417d6b3f3dc236b0b5b80fb00b3a791.png"), 'destination.png')

Although stretching to elements with position: absolute is not possible, there are often solutions where you can avoid the absolute positioning while obtaining the same effect. Look at this fiddle that solves the problem in your particular case http://jsfiddle.net/gS9q7/

The trick is to reverse element order by floating both elements, the first to the right, the second to the left, so the second appears first.

.child1 {
    width: calc(100% - 160px);
    float: right;
}
.child2 {
    width: 145px;
    float: left;
}

Finally, add a clearfix to the parent and you're done (see the fiddle for the complete solution).

Generally, as long as the element with absolute position is positioned at the top of the parent element, chances are good that you find a workaround by floating the element.

HTTP header names are case-insensitive, according to RFC 2616:

4.2:

Each header field consists of a name followed by a colon (":") and the field value. Field names are case-insensitive.

(Field values may or may not be case-sensitive.)

If you trust the major browsers to abide by this, you're all set.

BTW, unlike most of HTTP, methods (verbs) are case sensitive:

5.1.1 Method

The Method token indicates the method to be performed on the
resource identified by the Request-URI. The method is case-sensitive.

   Method         = "OPTIONS"                ; Section 9.2
                  | "GET"                    ; Section 9.3
                  | "HEAD"                   ; Section 9.4
                  | "POST"                   ; Section 9.5
                  | "PUT"                    ; Section 9.6
                  | "DELETE"                 ; Section 9.7
                  | "TRACE"                  ; Section 9.8
                  | "CONNECT"                ; Section 9.9
                  | extension-method
   extension-method = token

First installed

sudo apt-get install php5-gd

then

sudo apt-get install php5-intl

and last one was

sudo apt-get install php5-xsl

After that, it is installing as it should.

Instagram deprecated their legacy APIs in support for Basic Display API during the late 2019

In Basic Display API you are supposed to use the following API endpoint to get the media id. You will need to supply a valid access token.

https://graph.instagram.com/me/media?fields=id,caption&access_token={access-token}

You can read here on how to configure test account and generate access token on Facebook developer portal.

Here is another article which also describes about how to get access token.

You can use below code

$.when( Typer() ).done(function() {
       playBGM();
});

Your first CSS selector—social.h2—is looking for the "social" element in the "h2", class, e.g.:

<social class="h2">

Class selectors are proceeded with a dot (.). Also, use a space () to indicate that one element is inside of another. To find an <h2> descendant of an element in the social class, try something like:

.social h2 {
  color: pink;
  font-size: 14px;
}

To get a better understanding of CSS selectors and how they are used to reference your HTML, I suggest going through the interactive HTML and CSS tutorials from CodeAcademy. I hope that this helps point you in the right direction.

This is something to do with user permissions. Giving proper grants will solve this issue.

Step [1]: Open terminal and run this command

$ mysql -uroot -p

Output [1]: This should give you mysql prompt shown below

Step [2]:

mysql> CREATE USER 'parsa'@'localhost' IDENTIFIED BY 'your_password';
mysql> grant all privileges on *.* to 'parsa'@'localhost';

Syntax:

mysql> grant all privileges on `database_name`.`table_name` to 'user_name'@'hostname';

Note:

• hostname can be IP address, localhost, 127.0.0.1
• In database_name/table_name, * means all databases
• In hostname, to specify all hosts use '%'

Step [3]: Get out of current mysql prompt by either entering quit / exit command or press Ctrl+D.

Step [4]: Login to your new user

$ mysql -uparsa -pyour_password

Step [5]: Create the database

mysql> create database `database_name`;

For those of you who use SnapKit, just like me, the solution is anchoring your constraints to view.safeAreaLayoutGuide like so:

yourView.snp.makeConstraints { (make) in
    if #available(iOS 11.0, *) {
        //Bottom guide
        make.bottom.equalTo(view.safeAreaLayoutGuide.snp.bottomMargin)
        //Top guide
        make.top.equalTo(view.safeAreaLayoutGuide.snp.topMargin)
        //Leading guide
        make.leading.equalTo(view.safeAreaLayoutGuide.snp.leadingMargin)
        //Trailing guide
        make.trailing.equalTo(view.safeAreaLayoutGuide.snp.trailingMargin)

     } else {
        make.edges.equalToSuperview()
     }
}

Read the data:

foo <- read.table(text="1 349
  1 393
  1 392
  4 459
  3 49
  3 32
  2 94")

And sort:

foo[order(foo$V1),]

This relies on the fact that order keeps ties in their original order. See ?order.

Do C-b, :show which will show you all your current settings. /green, nnn will find you which properties have been set to green, the default. Do C-b, :set window-status-bg cyan and the bottom bar should change colour.

List available colours for tmux

You can tell more easily by the titles and the colours as they're actually set in your live session :show, than by searching through the man page, in my opinion. It is a very well-written man page when you have the time though.

If you don't like one of your changes and you can't remember how it was originally set, you can open do a new tmux session. To change settings for good edit ~/.tmux.conf with a line like set window-status-bg -g cyan. Here's mine: https://gist.github.com/9083598

Either of the latter two, since val could potentially be of a type that defines __eq__() to return true when passed None.
