In my case I didn't have an OracleService (OracleServiceORCL) in Windows Services.msc as described in Bharathi's answer.

I executed this command:

C:\> ORADIM -NEW -SID ORCL

and then the OracleService called OracleServiceORCL just showed up and got started in Services.msc. Really nice.

SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE')

The column STATUS tells you whether the object is VALID or INVALID. If it is invalid, you have to try a recompile, ORACLE can't tell you if it will work before.

Sample programs as follows and provided on link also https://oracle-concepts-learning.blogspot.com/

            name VARCHAR2(20);

I found how to run the query without error, but I hesitate to call it a "solution" without really understanding the underlying cause.

This more closely resembles the beginning of my actual query:

-- Comment
-- More comment
SELECT rf.flowrow, rf.stage, rf.process,
rf.instr instnum, rf.procedure_id, rtd_history.runtime, rtd_history.waittime
FROM
(
    -- Comment at beginning of subquery
    -- These two comment lines are the problem
    SELECT sub2.flowrow, sub2.stage, sub2.process, sub2.instr, sub2.pid
    FROM ( ...

The second set of comments above, at the beginning of the subquery, were the problem. When removed, the query executes. Other comments are fine. This is not a matter of some rogue or missing newline causing the following line to be commented, because the following line is a SELECT. A missing select would yield a different error than "not all variables bound."

I asked around and found one co-worker who has run into this -- comments causing query failures -- several times. Does anyone know how this can be the cause? It is my understanding that the very first thing a DBMS would do with comments is see if they contain hints, and if not, remove them during parsing. How can an ordinary comment containing no unusual characters (just letters and a period) cause an error? Bizarre.

I also had the similar problem recently with Oracle 12c. It got resolved after I changed the version of the ojdbc jar used. Replaced ojdbc14 with ojdbc6 jar.

I found this "solution" hidden in one of the comments. Since I was looking it up for a while, I'd like to highlight it a bit (can't yet comment or do such stuff...), so this is what I used:

SELECT * FROM (SELECT [Column] FROM [Table] ORDER BY [Date] DESC) WHERE ROWNUM = 1

This will print me the desired [Column] entry from the newest entry in the table, assuming that [Date] is always inserted via SYSDATE.

A very simple solution is to add the database name with your table name like if your DB name is DBMS and table is info then it will be DBMS.info for any query.

If your query is

select * from STUDENTREC where ROLL_NO=1;

it might show an error but

select * from DBMS.STUDENTREC where ROLL_NO=1; 

it doesn't because now actually your table is found.

You need to have your DBA modify the init.ora file, adding the directory you want to access to the 'utl_file_dir' parameter. Your database instance will then need to be stopped and restarted because init.ora is only read when the database is brought up.

You can view (but not change) this parameter by running the following query:

SELECT *
  FROM V$PARAMETER
  WHERE NAME = 'utl_file_dir'

Share and enjoy.

In my case, I was able to use a simple insert statement to bulk insert many rows into TABLE_A using just one column from TABLE_B and getting the other data elsewhere (sequence and a hardcoded value) :

INSERT INTO table_a (
    id,
    column_a,
    column_b
)
    SELECT
        table_a_seq.NEXTVAL,
        b.name,
        123
    FROM
        table_b b;

Result:

ID: NAME: CODE:
1, JOHN, 123
2, SAM, 123
3, JESS, 123

etc

An issue with the answer from Michal Foksa is that it adds the query parameters first, and then expands the path variables. If query parameter contains parenthesis, e.g. {foobar}, this will cause an exception.

The safe way is to expand the path variables first, and then add the query parameters:

String url = "http://test.com/Services/rest/{id}/Identifier";
Map<String, String> params = new HashMap<String, String>();
params.put("id", "1234");
URI uri = UriComponentsBuilder.fromUriString(url)
        .buildAndExpand(params)
        .toUri();
uri = UriComponentsBuilder
        .fromUri(uri)
        .queryParam("name", "myName")
        .build()
        .toUri();
restTemplate.exchange(uri , HttpMethod.PUT, requestEntity, class_p);

I tried this and it works without any issues to validate if the field is empty. I have answered your question partially as I haven't personally tried to add default values to attributes

if(field.getText()!= null && !field.getText().isEmpty())

Hope it helps

I found this plain JavaScript code very handy!

#<script type="text/javascript">
    function toggle_visibility(id) 
    {
        var e = document.getElementById(id);
        if ( e.style.display == 'block' )
            e.style.display = 'none';
        else
            e.style.display = 'block';
    }
</script>

bool is just a macro that expands to _Bool. You can use _Bool with no #include very much like you can use int or double; it is a C99 keyword.

The macro is defined in <stdbool.h> along with 3 other macros.

The macros defined are

• bool: macro expands to _Bool
• false: macro expands to 0
• true: macro expands to 1
• __bool_true_false_are_defined: macro expands to 1

You can solve this issue be adding max-width:

#element {
   width: 100vw;
   height: 100vw;
   max-width: 100%;
}

When you using CSS to make the wrapper full width using the code width: 100vw; then you will notice a horizontal scroll in the page, and that happened because the padding and margin of html and body tags added to the wrapper size, so the solution is to add max-width: 100%

To fix this issue you would have to download the file locally and run a cron job to keep updating. Note: this doesn't make your website any faster at all so its best to just ignore it.

For demonstration purposes however, follow this guide: http://diywpblog.com/leverage-browser-cache-optimize-google-analytics/

I think you cannot speak of a "conversion" here. That will be a whole project. To "convert" it i think you have to write it again for the iphone.

Have a look at this question:

Is there a multiplatform framework for developing iPhone / Android applications?

As you can see from the answers there, there is no good way of developing applications for both platforms at the same time (except if you're developing games where flash makes it easy to be portable).

$foo = 5;

$foo = $foo . "";

Now $foo is a string.

But, you may want to get used to casting. As casting is the proper way to accomplish something of that sort:

$foo = 5;
$foo = (string)$foo;

Another way is to encapsulate in quotes:

$foo = 5;
$foo = "$foo"

difference is that int the inner(equi/default)join and natural join that in the natuarl join common column win will be display in single time but inner/equi/default/simple join the common column will be display double time.

You could also use this:

$(this)[0].parentNode.remove();

Your regex ^[0-9] matches anything beginning with a digit, including strings like "1A". To avoid a partial match, append a $ to the end:

^[0-9]*$

This accepts any number of digits, including none. To accept one or more digits, change the * to +. To accept exactly one digit, just remove the *.

UPDATE: You mixed up the arguments to IsMatch. The pattern should be the second argument, not the first:

if (!System.Text.RegularExpressions.Regex.IsMatch(textbox.Text, "^[0-9]*$"))

CAUTION: In JavaScript, \d is equivalent to [0-9], but in .NET, \d by default matches any Unicode decimal digit, including exotic fare like ? (Myanmar 2) and ? (N'Ko 9). Unless your app is prepared to deal with these characters, stick with [0-9] (or supply the RegexOptions.ECMAScript flag).

I have made some researches on this subject recently. The way to implement it has to be different if the field is a TEXT field, a non unique field.

I have made some tests with a TEXT field. Considering the fact that we have a table with 1M entries. 37 entries are equal to 'something':

• SELECT * FROM test WHERE text LIKE '%something%' LIMIT 1 with mysql_num_rows() : 0.039061069488525s. (FASTER)
• SELECT count(*) as count FROM test WHERE text LIKE '%something% : 16.028197050095s.
• SELECT EXISTS(SELECT 1 FROM test WHERE text LIKE '%something%') : 0.87045907974243s.
• SELECT EXISTS(SELECT 1 FROM test WHERE text LIKE '%something%' LIMIT 1) : 0.044898986816406s.

But now, with a BIGINT PK field, only one entry is equal to '321321' :

• SELECT * FROM test2 WHERE id ='321321' LIMIT 1 with mysql_num_rows() : 0.0089840888977051s.
• SELECT count(*) as count FROM test2 WHERE id ='321321' : 0.00033879280090332s.
• SELECT EXISTS(SELECT 1 FROM test2 WHERE id ='321321') : 0.00023889541625977s.
• SELECT EXISTS(SELECT 1 FROM test2 WHERE id ='321321' LIMIT 1) : 0.00020313262939453s. (FASTER)

You have also a very good testing frameworks to create such a stub. One of my preferrable is Mockito There is also EasyMock and others... But Mockito is great you should read it - very elegant and powerfull package

Here are some steps for finding Time for your zone:

Date now = new Date();

 DateFormat df = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");  
 df.setTimeZone(TimeZone.getTimeZone("Europe/London"));  

 System.out.println("timeZone.......-->>>>>>"+df.format(now));  

The simplest option is to use a global variable. Then create a function that gets the current word.

current_word = ''
def oneFunction(lists):
    global current_word
    word=random.choice(lists[category])
    current_word = word

def anotherFunction():
    for letter in get_word():              
          print("_",end=" ")

 def get_word():
      return current_word

The advantage of this is that maybe your functions are in different modules and need to access the variable.

Adding label tags around the radio buttons using regular HTML will fix the 'labelfor' issue as well:

<label><%= Html.RadioButton("blah", !Model.blah) %> Yes</label>
<label><%= Html.RadioButton("blah", Model.blah) %> No</label>

Clicking on the text now selects the appropriate radio button.

First congrats that managed to figure out lambda. In my opinion this is really powerful construct to act with. The trend these days towards functional programming languages is surely an indicator that it neither should be avoided nor it will be redefined in the near future.

You just have to think a little bit different. I'm sure soon you will love it. But be careful if you deal only with python. Because the lambda is not a real closure, it is "broken" somehow: pythons lambda is broken

An object technically is a dictionary.

var myMappings = {
    mykey1: 'myValue',
    mykey2: 'myValue'
};

var myVal = myMappings['myKey1'];

alert(myVal); // myValue

You can even loop through one.

for(var key in myMappings) {
    var myVal = myMappings[key];
    alert(myVal);
}

There is no reason whatsoever to reinvent the wheel. And of course, assignment goes like:

myMappings['mykey3'] = 'my value';

And ContainsKey:

if (myMappings.hasOwnProperty('myKey3')) {
    alert('key already exists!');
}

A reminder that the .SaveAs function contains all optional arguments.I recommend removing CreatBackup:= False as it is not necessary.

The most interesting way I think is to create an object of the workbook and access the .SaveAs property that way. I have not tested it but you are never using Workbooks.Open rendering Application.AutomationSecurity inapplicable. Possibly saving resources and time as well.

" Pass by VALUE The value of a variable is passed along to the function If the function modifies that value, the modifications stay within the scope of that function.

Pass by REFERENCE A reference to the variable is passed along to the function If the function modifies that value, the modifications appear also within the scope of the calling function.

   Intent intentSMS = new Intent(Intent.ACTION_SENDTO, uriSms);   
   intentSMS.putExtra("sms_body", "The SMS text");   
   startActivity(intentSMS); 

See answer from Gary Makin. And you need change the format or data. Because the data that you have do not fit under the chosen format. For example this code works correct:

let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
let dateObj = dateFormatter.dateFromString("10 10 2001")
print("Dateobj: \(dateObj)")

First of all stop the server and image the disc. There's no point only having one shot at this. Then take a look here.

Solution using pagination with offset & limit:

public int collectionCount(String collection) {
        Integer page = 0;
        List<QueryDocumentSnapshot> snaps = new ArrayList<>();
        findDocsByPage(collection, page, snaps);
        return snaps.size();
    }

public void findDocsByPage(String collection, Integer page, 
                           List<QueryDocumentSnapshot> snaps) {
    try {
        Integer limit = 26000;
        FieldPath[] selectedFields = new FieldPath[] { FieldPath.of("id") };
        List<QueryDocumentSnapshot> snapshotPage;
        snapshotPage = fireStore()
                        .collection(collection)
                        .select(selectedFields)
                        .offset(page * limit)
                        .limit(limit)
                        .get().get().getDocuments();    
        if (snapshotPage.size() > 0) {
            snaps.addAll(snapshotPage);
            page++;
            findDocsByPage(collection, page, snaps);
        }
    } catch (InterruptedException | ExecutionException e) {
        e.printStackTrace();
    }
}

• findDocsPage it's a recursive method to find all pages of collection

• selectedFields for otimize query and get only id field instead full body of document

• limit max size of each query page

• page define inicial page for pagination

From the tests I did it worked well for collections with up to approximately 120k records!

A factory method a method that abstracts away the instantiation of an object. Generally factories are useful when you know that you need a new instance of a class that implements some interface but you don't know the implementing class.

This is useful when working with hierarchies of related classes, a good example of this would be a GUI toolkit. You could simply hard-code calls to the constructors for concrete implementations of each widget but if you ever wanted to swap one toolkit for another you'd have a lot of places to change. By using a factory you reduce the amount of code you would need to change.

If it's still of interest, here is an answer to a similar question: Convert HTTP Proxy to HTTPS Proxy in Twisted

To answer the second part of the question:

If yes, what kind of proxy server allows this?

Out of the box, most proxy servers will be configured to allow HTTPS connections only to port 443, so https URIs with custom ports wouldn't work. This is generally configurable, depending on the proxy server. Squid and TinyProxy support this, for example.

Go into yourForm.Designer.cs Scroll down to your textbox. Example below is for textBox2 object. Add this

this.textBox2.AutoSize = false;

and set its size to whatever you want

this.textBox2.Size = new System.Drawing.Size(142, 27);

Will work like a charm - without setting multiline to true, but only until you change any option in designer itself (you will have to set these 2 lines again). I think, this method is still better than multilining. I had a textbox for nickname in my app and with multiline, people sometimes accidentially wrote their names twice, like Thomas\nThomas (you saw only one in actual textbox line). With this solution, text is simply hiding to the left after each char too long for width, so its much safer for users, to put inputs.

As per @Nitsew's answer, Create your personal access token and use your token as your username and enter with blank password.

Later you won't need any credentials to access all your private repo(s).

No, don't do it that way.

From your Eclipse workspace, right click your project on the left pane -> Properties -> Java Build Path -> Add Jars -> add your jars here.

Tadaa!! :)

I didnt know about css3pie.com, a very useful site after seeing this post:

But what after testing it out it didnt work for me either. However I found that wrapping it in the .PHP file worked fine. So instead of:

behavior: url(PIE.htc);

use this:

behavior: url(PIE.php);

I put mine in a folder called jquery, so mine was:

 behavior: url(jquery/PIE.php);

So goto their downloads or get it here:

http://css3pie.com/download-latest

And use their PHP file. Inside the PHP file it explains that some servers are not configured for proper .HTC usage. And that was the problem I had.

Try it! I did, it works. Hope this helps others out too.

Try to Use JSON.stringify

Here is a great way to build dynamic fields for a pivot query:

--summarize values to a tmp table

declare @STR varchar(1000)
SELECT  @STr =  COALESCE(@STr +', ', '') 
+ QUOTENAME(DateRange) 
from (select distinct DateRange, ID from ##pivot)d order by ID

---see the fields generated

print @STr

exec('  .... pivot code ...
pivot (avg(SalesAmt) for DateRange IN (' + @Str +')) AS P
order by Decile')

First, disabling the index during the deletion would be helpful.

Try with a MERGE INTO statement :
1) create a temp table with IDs and an additional column from TABLE1 and test with the following

MERGE INTO table1 src
USING (SELECT id,col1
         FROM test_merge_delete) tgt
ON (src.id = tgt.id)
WHEN MATCHED THEN
  UPDATE
     SET src.col1 = tgt.col1
  DELETE
   WHERE src.id = tgt.id

You might want to push the object into the array

enter code here

var AssocArray = new Array();

AssocArray.push( "The letter A");

console.log("a = " + AssocArray[0]);

// result: "a = The letter A"

console.log( AssocArray[0]);

JSON.stringify(AssocArray);

After some googling, I found the advice to do the following, and it worked:

SQL> startup mount

ORACLE Instance started

SQL> recover database 

Media recovery complete

SQL> alter database open;

Database altered

Banging my usual drum solo of JUST TRY IT, here's how you can answer questions like that in the future:

$ cat junk.c
#include <stdio.h>

char* string = "Hello\0";

int main(int argv, char** argc)
{
    printf("-->%s<--\n", string);
}
$ gcc -S junk.c
$ cat junk.s

... eliding the unnecessary parts ...

.LC0:
    .string "Hello"
    .string ""

...

.LC1:
    .string "-->%s<--\n"

...

Note here how the string I used for printf is just "-->%s<---\n" while the global string is in two parts: "Hello" and "". The GNU assembler also terminates strings with an implicit NUL character, so the fact that the first string (.LC0) is in those two parts indicates that there are two NULs. The string is thus 7 bytes long. Generally if you really want to know what your compiler is doing with a certain hunk of code, isolate it in a dummy example like this and see what it's doing using -S (for GNU -- MSVC has a flag too for assembler output but I don't know it off-hand). You'll learn a lot about how your code works (or fails to work as the case may be) and you'll get an answer quickly that is 100% guaranteed to match the tools and environment you're working in.

Use the affix component included with Bootstrap. Start with a 'navbar-static-top' and this will change it to fixed when the height of your header (content above the navbar) is reached...

$('#nav').affix({
      offset: {
        top: $('header').height()
      }
});

No more than this IMHO - you can add the upper or lower methods

def count_letter_in_str(string,letter):
    return string.count(letter)

To have in Visual Studio Code what you can do in Sublime Text ( CTRL+K CTRL+U and CTRL+K CTRL+L ) you could do this:

• Open "Keyboard Shortcuts" with click on "File -> Preferences -> Keyboard Shortcuts"
• Click on "keybindings.json" link which appears under "Search keybindings" field

• Between the [] brackets add:

  {
      "key": "ctrl+k ctrl+u",
      "command": "editor.action.transformToUppercase",
      "when": "editorTextFocus"
  },
  {
      "key": "ctrl+k ctrl+l",
      "command": "editor.action.transformToLowercase",
      "when": "editorTextFocus"
  }
  

• Save and close "keybindings.json"

I was searching a solution to get height and width of an image using JavaScript. I found many, but all those solutions only worked when the image was present in browser cache.

Finally I found a solution to get the image height and width even if the image does not exist in the browser cache:

<script type="text/javascript">

  var imgHeight;
  var imgWidth;

  function findHHandWW() {
    imgHeight = this.height;
    imgWidth = this.width;
    return true;
  }

  function showImage(imgPath) {
    var myImage = new Image();
    myImage.name = imgPath;
    myImage.onload = findHHandWW;
    myImage.src = imgPath;
  }
</script>

break breaks out of a loop, not an if statement, as others have pointed out. The motivation for this isn't too hard to see; think about code like

for item in some_iterable:
    ...
    if break_condition():
        break 

The break would be pretty useless if it terminated the if block rather than terminated the loop -- terminating a loop conditionally is the exact thing break is used for.

I know rather old question but....came across looking other thing so I give my shot:

[each*2 for each in [1,2,3,4,5] if each % 10 == 0])

I suggest a more dynamic approach, without html coding into the page, keep it strictly JS:

$("a.AS-POST").on('click', e => {
  e.preventDefault()
  let frm = document.createElement('FORM')
  frm.id='frm_'+Math.random()
  frm.method='POST'
  frm.action=e.target.href
  document.body.appendChild(frm)
  frm.submit()
})

If you are using C#3 a good tip is to create an extension method to make this even simpler. Just create a static method (preferably in a static class) like so:

public static class Extensions
{
    public static string HtmlEncode(this string s)
    {
        return HttpUtility.HtmlEncode(s);
    }
}

You can then do neat stuff like this:

string encoded = "<div>I need encoding</div>".HtmlEncode();

Another solution is to actually create or login the user automatically if you already have the credentials handy. Here is how I do it using Plain JS.

function loginToFirebase(callback)
{
    let email = '[email protected]';
    let password = 'xxxxxxxxxxxxxx';
    let config =
    {
        apiKey: "xxx",
        authDomain: "xxxxx.firebaseapp.com",
        projectId: "xxx-xxx",
        databaseURL: "https://xxx-xxx.firebaseio.com",
        storageBucket: "gs://xx-xx.appspot.com",
    };

    if (!firebase.apps.length)
    {
        firebase.initializeApp(config);
    }

    let database = firebase.database();
    let storage = firebase.storage();

    loginFirebaseUser(email, password, callback);
}

function loginFirebaseUser(email, password, callback)
{
    console.log('Logging in Firebase User');

    firebase.auth().signInWithEmailAndPassword(email, password)
        .then(function ()
        {
            if (callback)
            {
                callback();
            }
        })
        .catch(function(login_error)
        {
            let loginErrorCode = login_error.code;
            let loginErrorMessage = login_error.message;

            console.log(loginErrorCode);
            console.log(loginErrorMessage);

            if (loginErrorCode === 'auth/user-not-found')
            {
                createFirebaseUser(email, password, callback)
            }
        });
}

function createFirebaseUser(email, password, callback)
{
    console.log('Creating Firebase User');

    firebase.auth().createUserWithEmailAndPassword(email, password)
        .then(function ()
        {
            if (callback)
            {
                callback();
            }
        })
        .catch(function(create_error)
        {
            let createErrorCode = create_error.code;
            let createErrorMessage = create_error.message;

            console.log(createErrorCode);
            console.log(createErrorMessage);
        });
}

Fixed the code for you:

ArrayList<Class> myArray= new ArrayList<Class>();

# Switch delimiter to //, so phpMyAdmin will not execute it line by line.
DELIMITER //
CREATE PROCEDURE usp_rateChapter12

(IN numRating_Chapter INT(11) UNSIGNED, 

 IN txtRating_Chapter VARCHAR(250),

 IN chapterName VARCHAR(250),

 IN addedBy VARCHAR(250)

)

BEGIN
DECLARE numRating_Chapter INT;

DECLARE txtRating_Chapter VARCHAR(250);

DECLARE chapterName1 VARCHAR(250);

DECLARE addedBy1 VARCHAR(250);

DECLARE chapterId INT;

DECLARE studentId INT;

SET chapterName1 = chapterName;
SET addedBy1 = addedBy;

SET chapterId = (SELECT chapterId 
                   FROM chapters 
                   WHERE chaptername = chapterName1);

SET studentId = (SELECT Id 
                   FROM students 
                   WHERE email = addedBy1);

SELECT chapterId;
SELECT studentId;

INSERT INTO ratechapter (rateBy, rateText, rateLevel, chapterRated)
VALUES (studentId, txtRating_Chapter, numRating_Chapter,chapterId);

END //

//DELIMITER;

This can be archived by adding code on the onchange event of the select control.

For Example:

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
    <option value="http://gmail.com">Gmail</option>
    <option value="http://youtube.com">Youtube</option>
</select>

Actually by this symbol we can call a class method that is static and not be dependent on other initialization...

class Test {

    public $name;

    public function __construct() {
        $this->name = 'Mrinmoy Ghoshal';
    }

    public static function doWrite($name) {
        print 'Hello '.$name;
    }

    public function write() {
        print $this->name;
    }
}

Here the doWrite() function is not dependent on any other method or variable, and it is a static method. That's why we can call this method by this operator without initializing the object of this class.

Test::doWrite('Mrinmoy'); // Output: Hello Mrinmoy.

But if you want to call the write method in this way, it will generate an error because it is dependent on initialization.

It seems that the most common method of achieving this is to draw a GPolygon with enough points to simulate a circle. The example you referenced uses this method. This page has a good example - look for the function drawCircle in the source code.

You can use set the layout_width or layout_width to 0dp (By the orientation you want to fill remaining space). Then use the layout_weight to make it fill remaining space.

This code works fine:

import os


def readFile(filename):
    filehandle = open(filename)
    print filehandle.read()
    filehandle.close()



fileDir = os.path.dirname(os.path.realpath('__file__'))
print fileDir

#For accessing the file in the same folder
filename = "same.txt"
readFile(filename)

#For accessing the file in a folder contained in the current folder
filename = os.path.join(fileDir, 'Folder1.1/same.txt')
readFile(filename)

#For accessing the file in the parent folder of the current folder
filename = os.path.join(fileDir, '../same.txt')
readFile(filename)

#For accessing the file inside a sibling folder.
filename = os.path.join(fileDir, '../Folder2/same.txt')
filename = os.path.abspath(os.path.realpath(filename))
print filename
readFile(filename)

If you want to change the format for all dates you can add a builder customizer. Here is an example of a bean that converts dates to ISO 8601:

@Bean
public Jackson2ObjectMapperBuilderCustomizer jsonCustomizer() {
    return new Jackson2ObjectMapperBuilderCustomizer() {
        @Override
        public void customize(Jackson2ObjectMapperBuilder builder) {
            builder.dateFormat(new ISO8601DateFormat());        
        }           
    };
}

Font Squirrel has a wonderful web font generator.

I think you should find what you need here to generate OTF fonts and the needed CSS to use them. It will even support older IE versions.

Follow the below steps to avoid (cannot convert between unicode and non-unicode string data types) this error

i) Add the Data conversion Transformation tool to your DataFlow.
ii) To open the DataFlow Conversion and select [string DT_STR] datatype.
iii) Then go to Destination flow, select Mapping.
iv) change your i/p name to copy of the name.

Here's an answer for 2017 on, where you probably only care about distinguishing <=IE11 from >IE11 ("Edge"):

@supports not (old: ie) { /* code for not old IE here */ }

More demonstrative example:

body:before { content: 'old ie'; }
/**/@supports not (old: ie) {
body:before { content: 'not old ie'; }
/**/}

This works because IE11 doesn't actually even support @supports, and all other relevant browser/version combinations do.

This is how it works for me (selecting control by ID and option by text):

protected void clickOptionInList(string listControlId, string optionText)
{
     driver.FindElement(By.XPath("//select[@id='"+ listControlId + "']/option[contains(.,'"+ optionText +"')]")).Click();
}

use:

clickOptionInList("ctl00_ContentPlaceHolder_lbxAllRoles", "Tester");

The Snack Sound Toolkit can play wav, au and mp3 files.

s = Sound() 
s.read('sound.wav') 
s.play()

I recently had the exact same issue and benefitted from the following post as well (in addition to Rohit5k2's solution above):

https://bsgconsultancy.wordpress.com/2015/09/13/convert-any-website-into-android-application-by-using-android-studio/

In Step 3, MainActivity extends Activity instead of ActionBarActivity (as Rohit5k2 mentioned). Putting the NoTitleBar and Fullscreen theme elements into the correct places in the AndroidManifest.xml file is also very important (take a look at Step 4).

Object Model is concerned with the following three concepts Data Abstraction Encapsulation Inheritance The relational model used the basic concept of a relation or table. Object-relational mapping (OR mapping) products integrate object programming language capabilities with relational databases.

I'm using Xcode 6 GM. I encountered the same issue. What I did was to go to Build Settings -> Build Options (you can search "compiler"), and then changed the option of the "Compiler for C/C++/Objective-C" to Default Compiler.

I found that by setting value field (not just what is given below) time input will be internally converted into the 24hr format.

Instead of a button, put a link and navigate it to another page

<a href="logout.php">Logout</a>

Then in logout.php page, use

session_start();
session_destroy();
header('Location: login.php');
exit;

Just looking for the right place to put this piece of code.

let's say you have the following property:

[Display(Name = "Solar Radiation (Average)", ShortName = "SolarRadiationAvg")]
public int SolarRadiationAvgSensorId { get; set; }

And you want to get the ShortName value. You can do:

((DisplayAttribute)(typeof(SensorsModel).GetProperty(SolarRadiationAvgSensorId).GetCustomAttribute(typeof(DisplayAttribute)))).ShortName;

Or to make it general:

internal static string GetPropertyAttributeShortName(string propertyName)
{
    return ((DisplayAttribute)(typeof(SensorsModel).GetProperty(propertyName).GetCustomAttribute(typeof(DisplayAttribute)))).ShortName;
}

Just to extend on the previous answer, if you are linking two requests together and want to send the cookies returned from the first one to the second one (for example, maintaining a session alive across requests) you can do:

import requests
r1 = requests.post('http://www.yourapp.com/login')
r2 = requests.post('http://www.yourapp.com/somepage',cookies=r1.cookies)

To summarize what was mentioned by Breno above

Say you have a variable with a path to a file

path = '/home/User/Desktop/myfile.py'

os.path.basename(path) returns the string 'myfile.py'

and

os.path.dirname(path) returns the string '/home/User/Desktop' (without a trailing slash '/')

These functions are used when you have to get the filename/directory name given a full path name.

In case the file path is just the file name (e.g. instead of path = '/home/User/Desktop/myfile.py' you just have myfile.py), os.path.dirname(path) returns an empty string.

Use git show, which also shows you the commit message, and defaults to the current commit when given no arguments.

Reading a CSV file in very simple and common in Java. You actually don't require to load any extra third party library to do this for you. CSV (comma separated value) file is just a normal plain-text file, store data in column by column, and split it by a separator (e.g comma ",").

In order to read specific columns from the CSV file, there are several ways. Simplest of all is as below:

Code to read CSV without any 3rd party library

BufferedReader br = new BufferedReader(new FileReader(csvFile));
while ((line = br.readLine()) != null) {
    // use comma as separator
    String[] cols = line.split(cvsSplitBy);
    System.out.println("Coulmn 4= " + cols[4] + " , Column 5=" + cols[5]);
}

If you notice, nothing special is performed here. It is just reading a text file, and spitting it by a separator – ",".

Consider an extract from legacy country CSV data at GeoLite Free Downloadable Databases

"1.0.0.0","1.0.0.255","16777216","16777471","AU","Australia"
"1.0.1.0","1.0.3.255","16777472","16778239","CN","China"
"1.0.4.0","1.0.7.255","16778240","16779263","AU","Australia"
"1.0.8.0","1.0.15.255","16779264","16781311","CN","China"
"1.0.16.0","1.0.31.255","16781312","16785407","JP","Japan"
"1.0.32.0","1.0.63.255","16785408","16793599","CN","China"
"1.0.64.0","1.0.127.255","16793600","16809983","JP","Japan"
"1.0.128.0","1.0.255.255","16809984","16842751","TH","Thailand"

Above code will output as below:

Column 4= "AU" , Column 5="Australia"
Column 4= "CN" , Column 5="China"
Column 4= "AU" , Column 5="Australia"
Column 4= "CN" , Column 5="China"
Column 4= "JP" , Column 5="Japan"
Column 4= "CN" , Column 5="China"
Column 4= "JP" , Column 5="Japan"
Column 4= "TH" , Column 5="Thailand"

You can, in fact, put the columns in a Map and then get the values simply by using the key.

You must assign it, like this:-

df['id']= df['id'].astype(str)

Those seem to be MySQL data types.

According to the documentation they take:

1. tinyint = 1 byte
2. smallint = 2 bytes
3. mediumint = 3 bytes
4. int = 4 bytes
5. bigint = 8 bytes

And, naturally, accept increasingly larger ranges of numbers.

Unless the role was made dbo, db_owner or db_datawriter, it won't have permission to edit any data. If you want to grant full edit permissions to a single table, do this:

GRANT ALL ON table1 TO doctor 

Users in that role will have no permissions whatsoever to other tables (not even read).

print df.sort_index(by='Frequency',ascending=False)

where by is the name of the column,if you want to sort the dataset based on column

Get Username and password

I had a similar problem, when I wanted to create a command, \dx, to abbreviate \;\mathrm{d}x (i.e. put an extra space before the differential of the integral and have the "d" upright as well). But then I also wanted to make it flexible enough to include the variable of integration as an optional argument. I put the following code in the preamble.

\usepackage{ifthen}

\newcommand{\dx}[1][]{%
   \ifthenelse{ \equal{#1}{} }
      {\ensuremath{\;\mathrm{d}x}}
      {\ensuremath{\;\mathrm{d}#1}}
}

Then

\begin{document}
   $$\int x\dx$$
   $$\int t\dx[t]$$
\end{document}

gives \dx with optional argument

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming

Update March 2013

Git 1.8.2 added the possibility to track branches.

"git submodule" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).

# add submodule to track master branch
git submodule add -b master [URL to Git repo];

# update your submodule
git submodule update --remote 

If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".

Also see Vogella's tutorial on submodules for general information on submodules.

Note:

git submodule add -b . [URL to Git repo];
                    ^^^

See git submodule man page:

A special value of . is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.

See commit b928922727d6691a3bdc28160f93f25712c565f6:

submodule add: If --branch is given, record it in .gitmodules

This allows you to easily record a submodule.<name>.branch option in .gitmodules when you add a new submodule. With this patch,

$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>

reduces to

$ git submodule add -b <branch> <repository> [<path>]

This means that future calls to

$ git submodule update --remote ...

will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):

A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log within that submodule.

So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:

• cd in the submodule
• git fetch/pull to make sure it has the latest commits on the right branch
• cd back in the parent repo
• add and commit in order to record the new commit of the submodule.

gitslave (that you already looked at) seems to be the best fit, including for the commit operation.

It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).

Other alternatives are detailed here.

In the particular case of repeating a single character, you can use std::string(size_type count, CharT ch):

std::string(5, '.') + "lolcat"

NB. This can't be used to repeat multi-character strings.

You can do it a number of ways, depending on the type of quotes you use:

• echo "<a href='http://www.whatever.com/$param'>Click here</a>";
• echo "<a href='http://www.whatever.com/{$param}'>Click here</a>";
• echo '<a href="http://www.whatever.com/' . $param . '">Click here</a>';
• echo "<a href=\"http://www.whatever.com/$param\">Click here</a>";

Double quotes allow for variables in the middle of the string, where as single quotes are string literals and, as such, interpret everything as a string of characters -- nothing more -- not even \n will be expanded to mean the new line character, it will just be the characters \ and n in sequence.

You need to be careful about your use of whichever type of quoting you decide. You can't use double quotes inside a double quoted string (as in your example) as you'll be ending the string early, which isn't what you want. You can escape the inner double quotes, however, by adding a backslash.

On a separate note, you might need to be careful about XSS attacks when printing unsafe variables (populated by the user) out to the browser.

class First(object):
  def __init__(self, a):
    print "first", a
    super(First, self).__init__(20)

class Second(object):
  def __init__(self, a):
    print "second", a
    super(Second, self).__init__()

class Third(First, Second):
  def __init__(self):
    super(Third, self).__init__(10)
    print "that's it"

t = Third()

Output is

first 10
second 20
that's it

Call to Third() locates the init defined in Third. And call to super in that routine invokes init defined in First. MRO=[First, Second]. Now call to super in init defined in First will continue searching MRO and find init defined in Second, and any call to super will hit the default object init. I hope this example clarifies the concept.

If you don't call super from First. The chain stops and you will get the following output.

first 10
that's it

Here's a way I've used in the past. Please note that you have to add a reference to the Microsoft Scripting Runtime so you can use the Dictionary object - if you don't want to add that reference you can do this with Collections but they're slower and there's no elegant way to check .Exists (you have to trap the error).

Dim OldVals As New Dictionary
Private Sub Worksheet_Change(ByVal Target As Range)
Dim cell As Range
    For Each cell In Target
        If OldVals.Exists(cell.Address) Then
            Debug.Print "New value of " & cell.Address & " is " & cell.Value & "; old value was " & OldVals(cell.Address)
        Else
            Debug.Print "No old value for " + cell.Address
        End If
        OldVals(cell.Address) = cell.Value
    Next
End Sub

Like any similar method, this has its problems - first off, it won't know the "old" value until the value has actually been changed. To fix this you'd need to trap the Open event on the workbook and go through Sheet.UsedRange populating OldVals. Also, it will lose all its data if you reset the VBA project by stopping the debugger or some such.

We used the following mod_rewrite rule:

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/test/
RewriteCond %{REQUEST_URI} !^/my-folder/
RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]

This redirects (permanently with a 301 redirect) all traffic to the site to http://www.newdomain.com, except requests to resources in the /test and /my-folder directories. We transfer the user to the exact resource they requested by using the (.*) capture group and then including $1 in the new URL. Mind the spaces.

You should first pull the changes from the develop branch and only then merge them to your branch:

git checkout develop 
git pull 
git checkout branch-x
git rebase develop

Or, when on branch-x:

git fetch && git rebase origin/develop

I have an alias that saves me a lot of time. Add to your ~/.gitconfig:

[alias]
    fr = "!f() { git fetch && git rebase origin/"$1"; }; f"

Now, all that you have to do is:

git fr develop

Additional pitfalls to watch out for when doing case insensitive compares:

Comparing as lower or as upper case? (common enough issue)

Both below will return 0 with strcicmpL("A", "a") and strcicmpU("A", "a").
Yet strcicmpL("A", "_") and strcicmpU("A", "_") can return different signed results as '_' is often between the upper and lower case letters.

This affects the sort order when used with qsort(..., ..., ..., strcicmp). Non-standard library C functions like the commonly available stricmp() or strcasecmp() tend to be well defined and favor comparing via lowercase. Yet variations exist.

int strcicmpL(char const *a, char const *b) {
  while (*b) {
    int d = tolower(*a) - tolower(*b);
    if (d) {
        return d;
    } 
    a++;
    b++;
  } 
  return tolower(*a);
}

int strcicmpU(char const *a, char const *b) {
  while (*b) {
    int d = toupper(*a) - toupper(*b);
    if (d) {
        return d;
    } 
    a++;
    b++;
  } 
  return toupper(*a);
}

char can have a negative value. (not rare)

touppper(int) and tolower(int) are specified for unsigned char values and the negative EOF. Further, strcmp() returns results as if each char was converted to unsigned char, regardless if char is signed or unsigned.

tolower(*a); // Potential UB
tolower((unsigned char) *a); // Correct (Almost - see following)

char can have a negative value and not 2's complement. (rare)

The above does not handle -0 nor other negative values properly as the bit pattern should be interpreted as unsigned char. To properly handle all integer encodings, change the pointer type first.

// tolower((unsigned char) *a);
tolower(*(const unsigned char *)a); // Correct

Locale (less common)

Although character sets using ASCII code (0-127) are ubiquitous, the remainder codes tend to have locale specific issues. So strcasecmp("\xE4", "a") might return a 0 on one system and non-zero on another.

Unicode (the way of the future)

If a solution needs to handle more than ASCII consider a unicode_strcicmp(). As C lib does not provide such a function, a pre-coded function from some alternate library is recommended. Writing your own unicode_strcicmp() is a daunting task.

Do all letters map one lower to one upper? (pedantic)

[A-Z] maps one-to-one with [a-z], yet various locales map various lower case chracters to one upper and visa-versa. Further, some uppercase characters may lack a lower case equivalent and again, visa-versa.

This obliges code to covert through both tolower() and tolower().

int d = tolower(toupper(*a)) - tolower(toupper(*b));

Again, potential different results for sorting if code did tolower(toupper(*a)) vs. toupper(tolower(*a)).

Portability

@B. Nadolson recommends to avoid rolling your own strcicmp() and this is reasonable, except when code needs high equivalent portable functionality.

Below is an approach that even performed faster than some system provided functions. It does a single compare per loop rather than two by using 2 different tables that differ with '\0'. Your results may vary.

static unsigned char low1[UCHAR_MAX + 1] = {
  0, 1, 2, 3, ...
  '@', 'a', 'b', 'c', ... 'z', `[`, ...  // @ABC... Z[...
  '`', 'a', 'b', 'c', ... 'z', `{`, ...  // `abc... z{...
}
static unsigned char low2[UCHAR_MAX + 1] = {
// v--- Not zero, but A which matches none in `low1[]`
  'A', 1, 2, 3, ...
  '@', 'a', 'b', 'c', ... 'z', `[`, ...
  '`', 'a', 'b', 'c', ... 'z', `{`, ...
}

int strcicmp_ch(char const *a, char const *b) {
  // compare using tables that differ slightly.
  while (low1[*(const unsigned char *)a] == low2[*(const unsigned char *)b]) {
    a++;
    b++;
  }
  // Either strings differ or null character detected.
  // Perform subtraction using same table.
  return (low1[*(const unsigned char *)a] - low1[*(const unsigned char *)b]);
}

What browser are you using? I entered your example and tried in both IE8 and Chrome and it validated fine when I typed in the value Sam's

 public class IndexViewModel
 {
    [Required(ErrorMessage="Required")]
    [RegularExpression("^([a-zA-Z0-9 .&'-]+)$", ErrorMessage = "Invalid First Name")]
    public string Name { get; set; }
 }

When I inspect the DOM using IE Developer toolbar and Chrome Developer mode it does not show any special characters.

Another way of simply telling if an element exists is to check the count()

if (myset.count(x)) {
   // x is in the set, count is 1
} else {
   // count zero, i.e. x not in the set
}

Most of the times, however, I find myself needing access to the element wherever I check for its existence.

So I'd have to find the iterator anyway. Then, of course, it's better to simply compare it to end too.

set< X >::iterator it = myset.find(x);
if (it != myset.end()) {
   // do something with *it
}

C++ 20

In C++20 set gets a contains function, so the following becomes possible as mentioned at: https://stackoverflow.com/a/54197839/895245

if (myset.contains(x)) {
  // x is in the set
} else {
  // no x 
}

\d means 'digit'. + means, '1 or more times'. So \d+ means one or more digit. It will match 12 and 1.

2018 10 25. Update.

Notepad++ 7.5.8 does not have plugin manager by default. You have to download plugins manually.

Keep in mind, if you use 64 bit version of Notepad++, you should also use 64 bit version of plugin. I had a similar issue here.

You can directly access the year and month attributes, or request a datetime.datetime:

In [15]: t = pandas.tslib.Timestamp.now()

In [16]: t
Out[16]: Timestamp('2014-08-05 14:49:39.643701', tz=None)

In [17]: t.to_pydatetime() #datetime method is deprecated
Out[17]: datetime.datetime(2014, 8, 5, 14, 49, 39, 643701)

In [18]: t.day
Out[18]: 5

In [19]: t.month
Out[19]: 8

In [20]: t.year
Out[20]: 2014

One way to combine year and month is to make an integer encoding them, such as: 201408 for August, 2014. Along a whole column, you could do this as:

df['YearMonth'] = df['ArrivalDate'].map(lambda x: 100*x.year + x.month)

or many variants thereof.

I'm not a big fan of doing this, though, since it makes date alignment and arithmetic painful later and especially painful for others who come upon your code or data without this same convention. A better way is to choose a day-of-month convention, such as final non-US-holiday weekday, or first day, etc., and leave the data in a date/time format with the chosen date convention.

The calendar module is useful for obtaining the number value of certain days such as the final weekday. Then you could do something like:

import calendar
import datetime
df['AdjustedDateToEndOfMonth'] = df['ArrivalDate'].map(
    lambda x: datetime.datetime(
        x.year,
        x.month,
        max(calendar.monthcalendar(x.year, x.month)[-1][:5])
    )
)

If you happen to be looking for a way to solve the simpler problem of just formatting the datetime column into some stringified representation, for that you can just make use of the strftime function from the datetime.datetime class, like this:

In [5]: df
Out[5]: 
            date_time
0 2014-10-17 22:00:03

In [6]: df.date_time
Out[6]: 
0   2014-10-17 22:00:03
Name: date_time, dtype: datetime64[ns]

In [7]: df.date_time.map(lambda x: x.strftime('%Y-%m-%d'))
Out[7]: 
0    2014-10-17
Name: date_time, dtype: object

Since you did not mention which version of Turbo C this method below will cover both v2 and v3.

My Swift code for change Navigation Bar title:

let attributes = [NSFontAttributeName : UIFont(name: "Roboto-Medium", size: 16)!, NSForegroundColorAttributeName : UIColor.whiteColor()]
self.navigationController.navigationBar.titleTextAttributes = attributes

And if you want to change background font too then I have this in my AppDelegate:

let attributes = [NSFontAttributeName : UIFont(name: "Roboto-Medium", size: 16)!, NSForegroundColorAttributeName : UIColor.whiteColor()]
UIBarButtonItem.appearance().setTitleTextAttributes(attributes, forState: UIControlState.Normal)

When you execute a program the child program inherits its environment variables from the parent. For instance if $HOME is set to /root in the parent then the child's $HOME variable is also set to /root.

This only applies to environment variable that are marked for export. If you set a variable at the command-line like

$ FOO="bar"

That variable will not be visible in child processes. Not unless you export it:

$ export FOO

You can combine these two statements into a single one in bash (but not in old-school sh):

$ export FOO="bar"

Here's a quick example showing the difference between exported and non-exported variables. To understand what's happening know that sh -c creates a child shell process which inherits the parent shell's environment.

$ FOO=bar
$ sh -c 'echo $FOO'

$ export FOO
$ sh -c 'echo $FOO'
bar

Note: To get help on shell built-in commands use help export. Shell built-ins are commands that are part of your shell rather than independent executables like /bin/ls.

Wget currently only supports x-www-form-urlencoded data. --post-file is not for transmitting files as form attachments, it expects data with the form: key=value&otherkey=example.

--post-data and --post-file work the same way: the only difference is that --post-data allows you to specify the data in the command line, while --post-file allows you to specify the path of the file that contain the data to send.

Here's the documentation:

 --post-data=string
       --post-file=file
           Use POST as the method for all HTTP requests and send the specified data
           in the request body.  --post-data sends string as data, whereas
           --post-file sends the contents of file.  Other than that, they work in
           exactly the same way. In particular, they both expect content of the
           form "key1=value1&key2=value2", with percent-encoding for special
           characters; the only difference is that one expects its content as a
           command-line parameter and the other accepts its content from a file. In
           particular, --post-file is not for transmitting files as form
           attachments: those must appear as "key=value" data (with appropriate
           percent-coding) just like everything else. Wget does not currently
           support "multipart/form-data" for transmitting POST data; only
           "application/x-www-form-urlencoded". Only one of --post-data and
           --post-file should be specified.

Regarding your authentication token, it should either be provided in the header, in the path of the url, or in the data itself. This must be indicated somewhere in the documentation of the service you use. In a POST request, as in a GET request, you must specify the data using keys and values. This way the server will be able to receive multiple information with specific names. It's similar with variables.

Hence, you can't just send a magic token to the server, you also need to specify the name of the key. If the key is "token", then it should be token=YOUR_TOKEN.

wget --post-data 'user=foo&password=bar' http://example.com/auth.php

Also, you should consider using curl if you can because it is easier to send files using it. There are many examples on the Internet for that.

I had a problem like this! I was able to fix it following

Step 1>>from Abraar Arique post, I went into the console>> Went under Style Editor and found Firefox wasn't loading the updated copy of my css file.

I cleared all history and reload the page then my problem was fixed.

The latest as of release of API 23 is

compile 'com.android.support:design:23.2.1'

We encountered this issue when trying to add a UNIQUE index to a VARCHAR(255) field using utf8mb4. While the problem is outlined well here already, I wanted to add some practical advice for how we figured this out and solved it.

When using utf8mb4, characters count as 4 bytes, whereas under utf8, they could as 3 bytes. InnoDB databases have a limit that indexes can only contain 767 bytes. So when using utf8, you can store 255 characters (767/3 = 255), but using utf8mb4, you can only store 191 characters (767/4 = 191).

You're absolutely able to add regular indexes for VARCHAR(255) fields using utf8mb4, but what happens is the index size is truncated at 191 characters automatically - like unique_key here:

This is fine, because regular indexes are just used to help MySQL search through your data more quickly. The whole field doesn't need to be indexed.

So, why does MySQL truncate the index automatically for regular indexes, but throw an explicit error when trying to do it for unique indexes? Well, for MySQL to be able to figure out if the value being inserted or updated already exists, it needs to actually index the whole value and not just part of it.

At the end of the day, if you want to have a unique index on a field, the entire contents of the field must fit into the index. For utf8mb4, this means reducing your VARCHAR field lengths to 191 characters or less. If you don't need utf8mb4 for that table or field, you can drop it back to utf8 and be able to keep your 255 length fields.

There are multiple meanings of "lock" in SVN and some of these answers that talk about "break lock" or a teammate holding a lock are not using the relevant meaning for the original question. This question is dealing with "working copy locks" (i.e. they are entirely local to the working copy on your computer and have nothing to do with you or teammates holding a lock/check-out on a file). The accepted answer by MicroEyes is referring to the correct usage and is your best option when this happens.

If a cleanup doesn't work you may need to check out a fresh working copy of the project. If you have any modified, un-commited files you will need to copy them over to the fresh working copy so you don't lose your changes.

See this page in the Tortoise SVN docs for a description of the three usages of "lock": http://tortoisesvn.net/docs/nightly/TortoiseSVN_en/tsvn-dug-locking.html

Excerpt (emphasis added):

The Three Meanings of “Lock”

In this section, and almost everywhere in this book, the words “lock” and “locking” describe a mechanism for mutual exclusion between users to avoid clashing commits. Unfortunately, there are two other sorts of “lock” with which Subversion, and therefore this book, sometimes needs to be concerned.

The second is working copy locks, used internally by Subversion to prevent clashes between multiple Subversion clients operating on the same working copy. Usually you get these locks whenever a command like update/commit/... is interrupted due to an error. These locks can be removed by running the cleanup command on the working copy, as described in the section called “Cleanup”.

...

I have solved it as follow.

import $ from 'jquery';

(function () {
    // ... code let script = $(..)
})();

Treat function as variable in your program so you can just pass them to other functions easily:

def test ():
   print "test was invoked"

def invoker(func):
   func()

invoker(test)  # prints test was invoked

You could also use INDEX MATCH, which is more "powerful" than vlookup. This would give you exactly what you are looking for:

okay, you can do this in one line of code. you'll need json2.js for this (you probably already have.). the two json objects here are unparsed strings.

json1 = '[{"foo":"bar"},{"bar":"foo"},{"name":"craig"}]';

json2 = '[{"foo":"baz"},{"bar":"fob"},{"name":"george"}]';

concattedjson = JSON.stringify(JSON.parse(json1).concat(JSON.parse(json2)));

Max heap Usage for the application is is 1024 MB

Maybe you could do it like this:

Don't use the model in first controller. Store data in some other shared object which could be then retrieved by second controller.

Look at this and this post. It's about the similar issue.

P.S.

You could probabbly use session scoped bean for that shared data...

If you are using Docker, you may try an image that has Ubuntu with System D already active with this command:

docker run -d --name redis --privileged -v /sys/fs/cgroup:/sys/fs/cgroup:ro jrei/systemd-ubuntu:18.04

Then you just need to run:

docker exec -it redis /bin/bash

and there you can just install Redis, start it, restart it or whatever you need.

Your problem looks like you are mixing DML & DDL operations. See this URL which explains this issue:

I had this problem when I reopened a project (which was developed on XCode 3.something on Leopard) after upgrading to Snow Leopard and XCode 3.2. Curious enough, it only affected some kinds of builds (emulator builds went fine, device ones gave me the error). And I have libxml2 at /usr/include, and it indeed contains libxml/tree.h.

Even the magic "Clean" did not work, but "Empty Caches..." under the "XCode" menu (between the Apple logo and File) did the trick (was that menu there in previous versions?). Beats me the reason, but after a clean there were no more complaints regarding libxml/tree.h

As Edan Maor explained, the quick and dirty way to do it (for [utc-16] encoded .xml files), which you should not do for the resons Edam Maor explained, can done with the following python 2.7 code in case time constraints do not allow you to learn (propper) XML parses.

Assuming you want to:

1. Delete the last line in the original xml file.
2. Add a line
3. substitute a line
4. Close the root tag.

It worked in python 2.7 modifying an .xml file named "b.xml" located in folder "a", where "a" was located in the "working folder" of python. It outputs the new modified file as "c.xml" in folder "a", without yielding encoding errors (for me) in further use outside of python 2.7.

pattern = '<Author>'
subst = '    <Author>' + domain + '\\' + user_name + '</Author>'
line_index =0 #set line count to 0 before starting
file = io.open('a/b.xml', 'r', encoding='utf-16')
lines = file.readlines()
outFile = open('a/c.xml', 'w')
for line in lines[0:len(lines)]:
    line_index =line_index +1
    if line_index == len(lines):
        #1. & 2. delete last line and adding another line in its place not writing it
        outFile.writelines("Write extra line here" + '\n')
        # 4. Close root tag:
        outFile.writelines("</phonebook>") # as in:
        #http://tizag.com/xmlTutorial/xmldocument.php
    else:
        #3. Substitue a line if it finds the following substring in a line:
        pattern = '<Author>'
        subst = '    <Author>' + domain + '\\' + user_name + '</Author>'
        if pattern in line:
            line = subst
            print line
        outFile.writelines(line)#just writing/copying all the lines from the original xml except for the last.

This was extremely helpful for me when trying to automate Cisco SIP phone configuration using an Excel spreadsheet as the source. My only issue was when I tried to make an array and populate it using $array | Add-Member ... as I needed to use it later on to generate the config file. Just defining an array and making it the for loop allowed it to store correctly.

$lastCell = 11 
$startRow, $model, $mac, $nOF, $ext = 1, 1, 5, 6, 7

$excel = New-Object -ComObject excel.application
$wb = $excel.workbooks.open("H:\Strike Network\Phones\phones.xlsx")
$sh = $wb.Sheets.Item(1)
$endRow = $sh.UsedRange.SpecialCells($lastCell).Row

$phoneData = for ($i=1; $i -le $endRow; $i++)
            {
                $pModel = $sh.Cells.Item($startRow,$model).Value2
                $pMAC = $sh.Cells.Item($startRow,$mac).Value2
                $nameOnPhone = $sh.Cells.Item($startRow,$nOF).Value2
                $extension = $sh.Cells.Item($startRow,$ext).Value2
                New-Object PSObject -Property @{ Model = $pModel; MAC = $pMAC; NameOnPhone = $nameOnPhone; Extension = $extension }
                $startRow++
            }

I used to have no issues adding information to an array with Add-Member but that was back in PSv2/3, and I've been away from it a while. Though the simple solution saved me manually configuring 100+ phones and extensions - which nobody wants to do.

IF you have tables A and B, both with colum C, here are the records, which are present in table A but not in B:

SELECT A.*
FROM A
    LEFT JOIN B ON (A.C = B.C)
WHERE B.C IS NULL

To get all the differences with a single query, a full join must be used, like this:

SELECT A.*, B.*
FROM A
    FULL JOIN B ON (A.C = B.C)
WHERE A.C IS NULL OR B.C IS NULL

What you need to know in this case is, that when a record can be found in A, but not in B, than the columns which come from B will be NULL, and similarly for those, which are present in B and not in A, the columns from A will be null.

go to package control by pressing Ctrl + Shift + p

type "remove package"

and type your package/plugin to uninstall and remove it

you can try to get it in a lot of ways :

1.Using media="bogus" and a <link> at the foot

<head>
    <!-- unimportant nonsense -->
    <link rel="stylesheet" href="style.css" media="bogus">
</head>
<body>
    <!-- other unimportant nonsense, such as content -->
    <link rel="stylesheet" href="style.css">
</body>

2.Inserting DOM in the old way

<script type="text/javascript">
(function(){
  var bsa = document.createElement('script');
     bsa.type = 'text/javascript';
     bsa.async = true;
     bsa.src = 'https://s3.buysellads.com/ac/bsa.js';
  (document.getElementsByTagName('head')[0]||document.getElementsByTagName('body')[0]).appendChild(bsa);
})();
</script>

3.if you can try plugins you could try loadCSS

<script>
  // include loadCSS here...
  function loadCSS( href, before, media ){ ... }
  // load a file
  loadCSS( "path/to/mystylesheet.css" );
</script>

I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)

public static bool IsStringType(object data)
    {
        return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
    }

In order to check the maximum allowed connections, you can run the following query:

SHOW VARIABLES LIKE "max_connections";

To check the number of active connections, you can run the following query:

SHOW VARIABLES LIKE "max_used_connections";

Hope it helps.

You don't really have to close it - Python will do it automatically either during garbage collection or at program exit. But as @delnan noted, it's better practice to explicitly close it for various reasons.

So, what you can do to keep it short, simple and explicit:

with open('pagehead.section.htm','r') as f:
    output = f.read()

Now it's just two lines and pretty readable, I think.

In Swift:

    // Save it to the camera roll / saved photo album
    // UIImageWriteToSavedPhotosAlbum(self.myUIImageView.image, nil, nil, nil) or 
    UIImageWriteToSavedPhotosAlbum(self.myUIImageView.image, self, "image:didFinishSavingWithError:contextInfo:", nil)

    func image(image: UIImage!, didFinishSavingWithError error: NSError!, contextInfo: AnyObject!) {
            if (error != nil) {
                // Something wrong happened.
            } else {
                // Everything is alright.
            }
    }

Test if your variable is an instance of numbers.Number:

>>> import numbers
>>> import decimal
>>> [isinstance(x, numbers.Number) for x in (0, 0.0, 0j, decimal.Decimal(0))]
[True, True, True, True]

This uses ABCs and will work for all built-in number-like classes, and also for all third-party classes if they are worth their salt (registered as subclasses of the Number ABC).

However, in many cases you shouldn't worry about checking types manually - Python is duck typed and mixing somewhat compatible types usually works, yet it will barf an error message when some operation doesn't make sense (4 - "1"), so manually checking this is rarely really needed. It's just a bonus. You can add it when finishing a module to avoid pestering others with implementation details.

This works starting with Python 2.6. On older versions you're pretty much limited to checking for a few hardcoded types.

I now found solution by using mysqli instead of mysql.

<?php 

// enable error reporting
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
//connect to database
$connection = mysqli_connect("hostname", "user", "password", "db", "port");

//run the store proc
$result = mysqli_query($connection, "CALL StoreProcName");

//loop the result set
while ($row = mysqli_fetch_array($result)){     
  echo $row[0] . " - " . + $row[1]; 
}

I found that many people seem to have a problem with using mysql_connect, mysql_query and mysql_fetch_array.

I had the same issue, the easiest way i found to insert the current date into a prepared statement is this one:

preparedStatement.setDate(1, new java.sql.Date(new java.util.Date().getTime()));

For me I had natualSort() and angularFileSort() in pipe which was reordering the files. I removed it and now it works fine for me

$.inject( // app/**/*.js files
    gulp.src(paths.jsFiles)
      .pipe($.plumber()), // use plumber so watch can start despite js errors
      //.pipe($.naturalSort())
      //.pipe($.angularFilesort()),
    {relative: true}))

Here's a working example for Nullable Enum return values:

public static TEnum? ParseOptional<TEnum>(this string value) where TEnum : struct
{
    return value == null ? (TEnum?)null : (TEnum) Enum.Parse(typeof(TEnum), value);
}

If you are in a domain environment, you can also use:

winrs -r:PCNAME cmd

This will open a remote command shell.

You can use Newtonsoft.Json, it's a dependency of Microsoft.AspNet.Mvc.ModelBinding which is a dependency of Microsoft.AspNet.Mvc. So, you don't need to add a dependency in your project.json.

#using Newtonsoft.Json
....
JsonConvert.DeserializeObject(json);

Note, using a WebAPI controller you don't need to deal with JSON.

UPDATE ASP.Net Core 3.0

Json.NET has been removed from the ASP.NET Core 3.0 shared framework.

You can use the new JSON serializer layers on top of the high-performance Utf8JsonReader and Utf8JsonWriter. It deserializes objects from JSON and serializes objects to JSON. Memory allocations are kept minimal and includes support for reading and writing JSON with Stream asynchronously.

To get started, use the JsonSerializer class in the System.Text.Json.Serialization namespace. See the documentation for information and samples.

To use Json.NET in an ASP.NET Core 3.0 project:

• Add a package reference to Microsoft.AspNetCore.Mvc.NewtonsoftJson
• Update ConfigureServices to call AddNewtonsoftJson().

    services.AddMvc()
        .AddNewtonsoftJson();

Read Json.NET support in Migrate from ASP.NET Core 2.2 to 3.0 Preview 2 for more information.

You can disable them altogether by

(setq make-backup-files nil)

as prior ans remove the height attrib. if u want your expansion along with its min height then use min-height: 102px instead of height: 102px.

note ie 6 and min-height http://www.dustindiaz.com/min-height-fast-hack/

I know the answer is in reply to a question asked 6 years ago ...

But I was looking for something similar for a few hours and then found out that: cut -c does exactly that, with an added bonus that you could also specify an offset.

cut -c 1-5 will return Hello and cut -c 7-11 will return world. No need for any other command

To disable a single rule for the rest of the file below:

/* eslint no-undef: "off"*/
const uploadData = new FormData();

There are three issues here that need to be fixed:

First is that you are expecting synchronous behavior while using stdout asynchronously. All of the calls in your run_cmd function are asynchronous, so it will spawn the child process and return immediately regardless of whether some, all, or none of the data has been read off of stdout. As such, when you run

console.log(foo.stdout);

you get whatever happens to be stored in foo.stdout at the moment, and there's no guarantee what that will be because your child process might still be running.

Second is that stdout is a readable stream, so 1) the data event can be called multiple times, and 2) the callback is given a buffer, not a string. Easy to remedy; just change

foo = new run_cmd(
    'netstat.exe', ['-an'], function (me, data){me.stdout=data;}
);

into

foo = new run_cmd(
    'netstat.exe', ['-an'], function (me, buffer){me.stdout+=buffer.toString();}
);

so that we convert our buffer into a string and append that string to our stdout variable.

Third is that you can only know you've received all output when you get the 'end' event, which means we need another listener and callback:

function run_cmd(cmd, args, cb, end) {
    // ...
    child.stdout.on('end', end);
}

So, your final result is this:

function run_cmd(cmd, args, cb, end) {
    var spawn = require('child_process').spawn,
        child = spawn(cmd, args),
        me = this;
    child.stdout.on('data', function (buffer) { cb(me, buffer) });
    child.stdout.on('end', end);
}

// Run C:\Windows\System32\netstat.exe -an
var foo = new run_cmd(
    'netstat.exe', ['-an'],
    function (me, buffer) { me.stdout += buffer.toString() },
    function () { console.log(foo.stdout) }
);

Change for Android 4.4+

Apps are not allowed to write (delete, modify ...) to external storage except to their package-specific directories.

As Android documentation states:

"Apps must not be allowed to write to secondary external storage devices, except in their package-specific directories as allowed by synthesized permissions."

However nasty workaround exists (see code below). Tested on Samsung Galaxy S4, but this fix does't work on all devices. Also I wouldn’t count on this workaround being available in future versions of Android.

There is a great article explaining (4.4+) external storage permissions change.

You can read more about workaround here. Workaround source code is from this site.

public class MediaFileFunctions 
{
    @TargetApi(Build.VERSION_CODES.HONEYCOMB)
    public static boolean deleteViaContentProvider(Context context, String fullname)

      Uri uri=getFileUri(context,fullname); 

      if (uri==null) 
      {
         return false;
      }

      try 
      { 
         ContentResolver resolver=context.getContentResolver();

         ContentValues contentValues = new ContentValues(); 
         int media_type = 1; 
         contentValues.put("media_type", media_type); 
         resolver.update(uri, contentValues, null, null); 

         return resolver.delete(uri, null, null) > 0; 
      } 
      catch (Throwable e) 
      { 
         return false;

      try
      { 
         contentResolver=context.getContentResolver(); 
         if (contentResolver == null)
            return null;

         uri=MediaStore.Files.getContentUri("external"); 
         String[] projection = new String[2]; 
         projection[0] = "_id"; 
         projection[1] = "_data";

                  String s = cursor.getString(dataColumn);

               }

                  uri = MediaStore.Files.getContentUri("external"); 
                  uri = contentResolver.insert(uri,contentValues); 
               } 
            } 
            catch (Throwable e) 
            { 
               uri = null; 
            }
            finally
            {
                cursor.close();
            }
         } 
      } 
      catch (Throwable e) 
      { 
         uri=null; 
      } 
      return uri; 
   } 
}

Use forward declarations where you can. If a class declaration only uses a pointer or reference to a type, you can just forward declare it and include the header for the type in the implementation file.

For example:

// T.h
class Class2; // Forward declaration

class T {
public:
    void doSomething(Class2 &c2);
private:
    Class2 *m_Class2Ptr;
};

// T.cpp
#include "Class2.h"
void Class2::doSomething(Class2 &c2) {
    // Whatever you want here
}

Fewer includes means far less work for the preprocessor if you do it enough.

Another possibility is to use bit sets, for which there is at least one package or you can use the built-in big package. In this case, basically you need to define a way to convert your object to an index.

The example you copied from is using data in the form of an array holding arrays, you are using data in the form of an array holding objects. Objects and arrays are not the same, and because of this they use different syntaxes for accessing data.

If you don't know the variable names, just do a var_dump($blog); within the loop to see them.

The simplest method - access $blog as an object directly:

Try (assuming those variables are correct):

<?php 
    foreach ($blogs as $blog) {
        $id         = $blog->id;
        $title      = $blog->title;
        $content    = $blog->content;
?>

<h1> <?php echo $title; ?></h1>
<h1> <?php echo $content; ?> </h1>

<?php } ?>

The alternative method - access $blog as an array:

Alternatively, you may be able to turn $blog into an array with get_object_vars (documentation):

<?php
    foreach($blogs as &$blog) {
        $blog     = get_object_vars($blog);
        $id       = $blog['id'];
        $title    = $blog['title'];
        $content  = $blog['content'];
?>

<h1> <?php echo $title; ?></h1>
<h1> <?php echo $content; ?> </h1>

<?php } ?> 

It's worth mentioning that this isn't necessarily going to work with nested objects so its viability entirely depends on the structure of your $blog object.

Better than either of the above - Inline PHP Syntax

Having said all that, if you want to use PHP in the most readable way, neither of the above are right. When using PHP intermixed with HTML, it's considered best practice by many to use PHP's alternative syntax, this would reduce your whole code from nine to four lines:

<?php foreach($blogs as $blog): ?>
    <h1><?php echo $blog->title; ?></h1>
    <p><?php echo $blog->content; ?></p>
<?php endforeach; ?>

Hope this helped.

I think, you haven't selected device or emulator , on which running your application,

In eclipse go to DDMS Perspective and select device or emulator on which you are running your application.

(Note: No need to restart the Eclipse)

The simplest way would be to use https://github.com/mitchellh/mapstructure

import "github.com/mitchellh/mapstructure"

mapstructure.Decode(myData, &result)

If you want to do it yourself, you could do something like this:

http://play.golang.org/p/tN8mxT_V9h

func SetField(obj interface{}, name string, value interface{}) error {
    structValue := reflect.ValueOf(obj).Elem()
    structFieldValue := structValue.FieldByName(name)

    if !structFieldValue.IsValid() {
        return fmt.Errorf("No such field: %s in obj", name)
    }

    if !structFieldValue.CanSet() {
        return fmt.Errorf("Cannot set %s field value", name)
    }

    structFieldType := structFieldValue.Type()
    val := reflect.ValueOf(value)
    if structFieldType != val.Type() {
        return errors.New("Provided value type didn't match obj field type")
    }

    structFieldValue.Set(val)
    return nil
}

type MyStruct struct {
    Name string
    Age  int64
}

func (s *MyStruct) FillStruct(m map[string]interface{}) error {
    for k, v := range m {
        err := SetField(s, k, v)
        if err != nil {
            return err
        }
    }
    return nil
}

func main() {
    myData := make(map[string]interface{})
    myData["Name"] = "Tony"
    myData["Age"] = int64(23)

    result := &MyStruct{}
    err := result.FillStruct(myData)
    if err != nil {
        fmt.Println(err)
    }
    fmt.Println(result)
}

There is no ENDIF in SQL.

The statement directly followig an IF is execute only when the if expression is true.

The BEGIN ... END construct is separate from the IF. It binds multiple statements together as a block that can be treated as if they were a single statement. Hence BEGIN ... END can be used directly after an IF and thus the whole block of code in the BEGIN .... END sequence will be either executed or skipped.

In your case I suspect the "(more code)" following FROM XXXXX is where your problem is.

If you're on macOS and installed postgres via homebrew, try restarting it with

brew services restart postgresql

If you're on Ubuntu, you can restart it with either one of these commands

sudo service postgresql restart

sudo /etc/init.d/postgresql restart

For reference, cursor.rowcount will only return on CREATE, UPDATE and DELETE statements:

 |  rowcount
 |      This read-only attribute specifies the number of rows the last DML statement
 |      (INSERT, UPDATE, DELETE) affected.  This is set to -1 for SELECT statements.

Without Using Arrays, you can store the Characters and concatenate them in reverse order.

public static String reverseString(String inpt) {

    String sb = "";
    for(int i = inpt.length()-1; i>=0; i--) {

        sb = sb.concat(""+inpt.charAt(i));
    }

    return sb;
}

The solutions given here (renaming the branch in 'master') don't insist on the consequences for the remote (GitHub) repo:

• if you hadn't push anything since making that branch, you can rename it and push it without any problem.
• if you had push master on GitHub, you will need to 'git push -f' the new branch: you can no longer push in a fast forward mode.

    -f
    --force

Usually, the command refuses to update a remote ref that is not an ancestor of the local ref used to overwrite it. This flag disables the check. This can cause the remote repository to lose commits; use it with care.

If others have already pulled your repo, they won't be able to pull that new master history without replacing their own master with that new GitHub master branch (or dealing with lots of merges).
There are alternatives to a git push --force for public repos.
Jefromi's answer (merging the right changes back to the original master) is one of them.

You can't update with a number greater than 1 for datatype number(2,2) is because, the first parameter is the total number of digits in the number and the second one (.i.e 2 here) is the number of digits in decimal part. I guess you can insert or update data < 1. i.e. 0.12, 0.95 etc.

Please check NUMBER DATATYPE in NUMBER Datatype.

something like this:

List<string> test1 = new List<string> { "@bob.com", "@tom.com" };
List<string> test2 = new List<string> { "[email protected]", "[email protected]" };

var res = test2.Where(f => test1.Count(z => f.Contains(z)) == 0)

Live example: here

REST is using the various HTTP methods (mainly GET/PUT/DELETE) to manipulate data.

Rather than using a specific URL to delete a method (say, /user/123/delete), you would send a DELETE request to the /user/[id] URL, to edit a user, to retrieve info on a user you send a GET request to /user/[id]

For example, instead a set of URLs which might look like some of the following..

GET /delete_user.x?id=123
GET /user/delete
GET /new_user.x
GET /user/new
GET /user?id=1
GET /user/id/1

You use the HTTP "verbs" and have..

GET /user/2
DELETE /user/2
PUT /user

One-to-many and Many-to-one relationship is talking about the same logical relationship, eg an Owner may have many Homes, but a Home can only have one Owner.

So in this example Owner is the One, and Homes are the Many. Each Home always has an owner_id (eg the Foreign Key) as an extra column.

The difference in implementation between these two, is which table defines the relationship. In One-to-Many, the Owner is where the relationship is defined. Eg, owner1.homes lists all the homes with owner1's owner_id In Many-to-One, the Home is where the relationship is defined. Eg, home1.owner lists owner1's owner_id.

I dont actually know in what instance you would implement the many-to-one arrangement, because it seems a bit redundant as you already know the owner_id. Perhaps its related to cleanness of deletions and changes.

I have found it satisfactory to use ls and cd within ipython notebook to find the file. Then type cat your_file_name into the cell, and you'll get back the contents of the file, which you can then paste into the cell as code.

This is not ideal as it removes all, but might work for your needs:

z = document.querySelector('video');
z.parentNode.replaceChild(z.cloneNode(1), z);

Cloning a node copies all of its attributes and their values, including intrinsic (in–line) listeners. It does not copy event listeners added using addEventListener()

Node.cloneNode()

@RobinL as mentioned in previous comments, you can use chart.series[n].setData(). First you need to make sure you’ve assigned a chart instance to the chart variable, that way it adopts all the properties and methods you need to access and manipulate the chart.

I’ve also used the second parameter of setData() and had it false, to prevent automatic rendering of the chart. This was because I have multiple data series, so I’ll rather update each of them, with render=false, and then running chart.redraw(). This multiplied performance (I’m having 10,000-100,000 data points and refreshing the data set every 50 milliseconds).

If you inherit from Exception, you have to provide a constructor that takes a String as a parameter (it will contain the error message).

ls whateveryouwant | xargs -n 1 basename

Does that work for you?

Otherwise you can (cd /the/directory && ls) (yes, parentheses intended)

I wanted to bind a particular data to dropdown and it should be distinct. I did the following:

List<ClassDetails> classDetails;

ddlData.Databind();

Both answers to this questions are correct, but I was still missing a complete, short solution to backup a Github repository into a local file. The gist is available here, feel free to fork or adapt to your needs.

backup.sh:

#!/bin/bash
# Backup the repositories indicated in the command line
# Example:
# bin/backup user1/repo1 user1/repo2
set -e
for i in $@; do
  FILENAME=$(echo $i | sed 's/\//-/g')
  echo "== Backing up $i to $FILENAME.bak"
  git clone [email protected]:$i $FILENAME.git --mirror
  cd "$FILENAME.git"
  git bundle create ../$FILENAME.bak --all
  cd ..
  rm -rf $i.git
  echo "== Repository saved as $FILENAME.bak"
done

restore.sh:

#!/bin/bash
# Restore the repository indicated in the command line
# Example:
# bin/restore filename.bak
set -e

FOLDER_NAME=$(echo $1 | sed 's/.bak//')
git clone --bare $1 $FOLDER_NAME.git

You can do it without dealing with encoding by using BlockCopy:

char[] chars = new char[bytes.Length / sizeof(char)];
System.Buffer.BlockCopy(bytes, 0, chars, 0, bytes.Length);
string str = new string(chars);

var validator = $("#myForm").validate();
validator.destroy();

This will destroy all the validation errors

window.location.href = "webpage.htm";

Make sure that you're using the same Servlet API specification that your Web container supports. Refer to this chart if you're using Tomcat: http://tomcat.apache.org/whichversion.html

The Web container that you use will definitely have the API jars you require.

Tomcat 6 for example has it in apache-tomcat-6.0.26/lib/servlet-api.jar

    int fd;
    struct ifreq ifr;
    char *iface = "enp0s3";
    unsigned char *mac = NULL;

    memset(&ifr, 0, sizeof(ifr));

    fd = socket(AF_INET, SOCK_DGRAM, 0);

    ifr.ifr_addr.sa_family = AF_INET;
    strncpy(ifr.ifr_name , iface , IFNAMSIZ-1);

    if (0 == ioctl(fd, SIOCGIFHWADDR, &ifr)) {
        mac = (unsigned char *)ifr.ifr_hwaddr.sa_data;

        //display mac address
        printf("Mac : %.2X:%.2X:%.2X:%.2X:%.2X:%.2X\n" , mac[0], mac[1], mac[2], mac[3], mac[4], mac[5]);
    }

    close(fd);

    return 0;
}

The first thing you need to decide is whether the data structure needs to be mutable or not. As has been mentioned, lists are mutable, tuples are not. This also means that tuples can be used for dictionary keys, wheres lists cannot.

In my experience, tuples are generally used where order and position is meaningful and consistant. For example, in creating a data structure for a choose your own adventure game, I chose to use tuples instead of lists because the position in the tuple was meaningful. Here is one example from that data structure:

pages = {'foyer': {'text' : "some text", 
          'choices' : [('open the door', 'rainbow'),
                     ('go left into the kitchen', 'bottomless pit'),
                     ('stay put','foyer2')]},}

The first position in the tuple is the choice displayed to the user when they play the game and the second position is the key of the page that choice goes to and this is consistent for all pages.

Tuples are also more memory efficient than lists, though I'm not sure when that benefit becomes apparent.

Also check out the chapters on lists and tuples in Think Python.

In the most simple terms extends is used to inherit from a class and implements is used to apply an interface in your class

extends:

public class Bicycle {
    //properties and methods
}
public class MountainBike extends Bicycle {
    //new properties and methods
}

implements:

public interface Relatable {
    //stuff you want to put
}
public class RectanglePlus implements Relatable {
    //your class code
}

if you still have confusion read this: https://docs.oracle.com/javase/tutorial/java/IandI/subclasses.html https://docs.oracle.com/javase/tutorial/java/IandI/usinginterface.html

Try this simple LINQ:

//For a file list/array
var files = Directory.GetFiles(folderPath, "*.*", SearchOption.AllDirectories);

//simply use Where ! x.Contains
var notContain = files.Where(x => ! x.Contains(@"\$RECYCLE.BIN\")).ToList();

//Or use Except()
var containing = files.Where(x => x.Contains(@"\$RECYCLE.BIN\")).ToList();
    notContain = files.Except(containing).ToList();

As per the other posting here, the best solution is to use the CSS entry of

style="border:0;"

Sure you can create an html template and I would recommend also a text template. In the template you can just put [BODY] in the place where the body would be placed and then you can just read in the template and replace the body with the new content. You can send the email using .Nets Mail Class. You just have to loop through the sending of the email to all recipients after you create the email initially. Worked like a charm for me.

using System.Net.Mail;

// Email content
string HTMLTemplatePath = @"path";
string TextTemplatePath = @"path";
string HTMLBody = "";
string TextBody = "";

HTMLBody = File.ReadAllText(HTMLTemplatePath);
TextBody = File.ReadAllText(TextTemplatePath);

HTMLBody = HTMLBody.Replace(["[BODY]", content);
TextBody = HTMLBody.Replace(["[BODY]", content);

// Create email code
MailMessage m = new MailMessage();

m.From = new MailAddress("[email protected]", "display name");
m.To.Add("[email protected]");
m.Subject = "subject";

AlternateView plain = AlternateView.CreateAlternateViewFromString(_EmailBody + text, new System.Net.Mime.ContentType("text/plain"));
AlternateView html = AlternateView.CreateAlternateViewFromString(_EmailBody + body, new System.Net.Mime.ContentType("text/html"));
mail.AlternateViews.Add(plain);
mail.AlternateViews.Add(html);

SmtpClient smtp = new SmtpClient("server");
smtp.Send(m);

You can add and retrieve a numpy array from dataframe using this:

import numpy as np
import pandas as pd

df = pd.DataFrame({'b':range(10)}) # target dataframe
a = np.random.normal(size=(10,2)) # numpy array
df['a']=a.tolist() # save array
np.array(df['a'].tolist()) # retrieve array

This builds on the previous answer that confused me because of the sparse part and this works well for a non-sparse numpy arrray.

If I use exit() in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing. See here

But sys.exit() is better in this case. It closes the program and doesn't create any dialogue box.

when I send only one object from the client to server all works well.

when I attempt to send several objects one after another on the same stream I get StreamCorruptedException.

Actually, your client code is writing one object to the server and reading multiple objects from the server. And there is nothing on the server side that is writing the objects that the client is trying to read.

You want has_key?:

if(params.has_key?(:one) && params.has_key?(:two))

Just checking if(params[:one]) will get fooled by a "there but nil" and "there but false" value and you're asking about existence. You might need to differentiate:

• Not there at all.
• There but nil.
• There but false.
• There but an empty string.

as well. Hard to say without more details of your precise situation.

You were on the right track with your "ng-keydown" attribute on the input, but you missed a simple step. Just because you put the ng-keydown attribute there, doesn't mean angular knows what to do with it. That's where "directives" come into play. You used the attribute correctly, but you now need to write a directive that will tell angular what to do when it sees that attribute on an html element.

The following is an example of how you would do that. We'll rename the directive from ng-keydown to on-keydown (to avoid breaking the "best practice" found here):

var mod = angular.module('mydirectives');
mod.directive('onKeydown', function() {
    return {
        restrict: 'A',
        link: function(scope, elem, attrs) {
             // this next line will convert the string
             // function name into an actual function
             var functionToCall = scope.$eval(attrs.ngKeydown);
             elem.on('keydown', function(e){
                  // on the keydown event, call my function
                  // and pass it the keycode of the key
                  // that was pressed
                  // ex: if ENTER was pressed, e.which == 13
                  functionToCall(e.which);
             });
        }
    };
});

The directive simple tells angular that when it sees an HTML attribute called "ng-keydown", it should listen to the element that has that attribute and call whatever function is passed to it. In the html you would have the following:

<input type="text" on-keydown="onKeydown">

And then in your controller (just like you already had), you would add a function to your controller's scope that is called "onKeydown", like so:

$scope.onKeydown = function(keycode){
    // do something with the keycode
}

Hopefully that helps either you or someone else who wants to know

This query will return details about foreign keys in a table, it supports multiple column keys.

    SELECT *
    FROM
    (
    SELECT 
    T1.constraint_name ConstraintName,
    T2.COLUMN_NAME ColumnName,
    T3.TABLE_NAME RefTableName, 
    T3.COLUMN_NAME RefColumnName,
    T1.MATCH_OPTION MatchOption, 
    T1.UPDATE_RULE UpdateRule, 
    T1.DELETE_RULE DeleteRule
    FROM 
    INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS T1
    INNER JOIN
    INFORMATION_SCHEMA.KEY_COLUMN_USAGE T2 
    ON T1.CONSTRAINT_NAME = T2.CONSTRAINT_NAME
    INNER JOIN
    INFORMATION_SCHEMA.KEY_COLUMN_USAGE T3 
    ON T1.UNIQUE_CONSTRAINT_NAME = T3.CONSTRAINT_NAME 
    AND T2.ORDINAL_POSITION = T3.ORDINAL_POSITION) A
    WHERE A.ConstraintName = 'table_name'

Use the code below it worked for me.

MediaPlayer mp = new MediaPlayer();
mp.setDataSource("/mnt/sdcard/yourdirectory/youraudiofile.mp3");
mp.prepare();
mp.start();

Afterall, you could edit the .vimrc,then add the conf

set tabstop=4

Or exec the command

I know this post is old but I just wanted to add my answer!

You said to log a user out WITHOUT directing... this method DOES redirect but it returns the user to the page they were on! here's my implementation:

// every page with logout button
<?php
        // get the full url of current page
        $page = $_SERVER['PHP_SELF'];
        // find position of the last '/'
        $file_name_begin_pos = strripos($page, "/");
        // get substring from position to end 
        $file_name = substr($page, ++$fileNamePos);
    }
?>

// the logout link in your html
<a href="logout.php?redirect_to=<?=$file_name?>">Log Out</a>

// logout.php page
<?php
    session_start();
    $_SESSION = array();
    session_destroy();
    $page = "index.php";
    if(isset($_GET["redirect_to"])){
        $file = $_GET["redirect_to"];
        if ($file == "user.php"){
            // if redirect to is a restricted page, redirect to index
            $file = "index.php";
        }
    }
    header("Location: $file");
?>

and there we go!

the code that gets the file name from the full url isn't bug proof. for example if query strings are involved with un-escaped '/' in them, it will fail.

However there are many scripts out there to get the filename from url!

Happy Coding!

What you are trying to do is very dangerous. Think about this carefully. There is a very good reason for the default behaviour of auto increment.

Consider this:

A record is deleted in one table that has a relationship with another table. The corresponding record in the second table cannot be deleted for auditing reasons. This record becomes orphaned from the first table. If a new record is inserted into the first table, and a sequential primary key is used, this record is now linked to the orphan. Obviously, this is bad. By using an auto incremented PK, an id that has never been used before is always guaranteed. This means that orphans remain orphans, which is correct.

Simplest way, get a launchpad account and use: ssh-import-id

I am quite late but any user searching for this can get help from it. Inside the options you can pass a new parameter called chartArea.

        var options = {
        chartArea:{left:10,top:20,width:"100%",height:"100%"}
    };

Left and top options will define the amount of padding from left and top. Hope this will help.

I had a similar problem. I am posting my solution here because I believe it might help one of the commenters.

For me, the obstacle was that the page required a login and then gave me a new URL through javascript. Here is what I had to do:

curl -c cookiejar -g -O -J -L -F "j_username=username" -F "j_password=password" <URL>

Note that j_username and j_password is the name of the fields for my website's login form. You will have to open the source of the webpage to see what the 'name' of the username field and the 'name' of the password field is in your case. After that I go an html file with java script in which the new URL was embedded. After parsing this out just resubmit with the new URL:

curl -c cookiejar -g -O -J -L -F "j_username=username" -F "j_password=password" <NEWURL>

The first 2 examples act very differently if you are REPLACING them by something. If you match on this:

str = str.replace(/^(7|8|9)/ig,''); 

you would replace 7 or 8 or 9 by the empty string.

If you match on this

str = str.replace(/^[7|8|9]/ig,''); 

you will replace 7 or 8 or 9 OR THE VERTICAL BAR!!!! by the empty string.

I just found this out the hard way.

If you want to add item to the beginning of the collection you can use prepend:

$item->prepend($product, 'key');

You have 2 choices:

1) Either specify the column name list (without the identity column).

2) SET IDENTITY_INSERT tablename ON, followed by insert statements that provide explicit values for the identity column, followed by SET IDENTITY_INSERT tablename OFF.

If you are avoiding a column name list, perhaps this 'trick' might help?:

-- Get a comma separated list of a table's column names
SELECT STUFF(
(SELECT 
',' + COLUMN_NAME AS [text()]
FROM 
INFORMATION_SCHEMA.COLUMNS
WHERE 
TABLE_NAME = 'TableName'
Order By Ordinal_position
FOR XML PATH('')
), 1,1, '')

Great Thanks to @Massimo Cafaro and Shaybc I was able achieve below tasks

in iOS 8 :

Record audio & Save

Play Saved Recording

1.Add "AVFoundation.framework" to your project

in .h file

2.Add below import statement 'AVFoundation/AVFoundation.h'.

3.Define "AVAudioRecorderDelegate"

4.Create a layout with Record, Play buttons and their action methids

5.Define Recorder and Player etc.

Here is the complete example code which may help you.

ViewController.h

#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>

@interface ViewController : UIViewController <AVAudioRecorderDelegate>

@property(nonatomic,strong) AVAudioRecorder *recorder;
@property(nonatomic,strong) NSMutableDictionary *recorderSettings;
@property(nonatomic,strong) NSString *recorderFilePath;
@property(nonatomic,strong) AVAudioPlayer *audioPlayer;
@property(nonatomic,strong) NSString *audioFileName;

- (IBAction)startRecording:(id)sender;
- (IBAction)stopRecording:(id)sender;

- (IBAction)startPlaying:(id)sender;
- (IBAction)stopPlaying:(id)sender;

@end

Then do the job in

ViewController.m

#import "ViewController.h"

#define DOCUMENTS_FOLDER [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]

@interface ViewController ()
@end

@implementation ViewController

@synthesize recorder,recorderSettings,recorderFilePath;
@synthesize audioPlayer,audioFileName;

More general sorted, where the key keyword defines the sorting method, minus before numerical type indicates descending:

>>> x = Counter({'a':5, 'b':3, 'c':7})
>>> sorted(x.items(), key=lambda k: -k[1])  # Ascending
[('c', 7), ('a', 5), ('b', 3)]

If your str() or list() objects might end up being empty as so: astr = '' or alist = [], then you might want to use alist[-1:] instead of alist[-1] for object "sameness".

The significance of this is:

alist = []
alist[-1]   # will generate an IndexError exception whereas 
alist[-1:]  # will return an empty list
astr = ''
astr[-1]    # will generate an IndexError exception whereas
astr[-1:]   # will return an empty str

Where the distinction being made is that returning an empty list object or empty str object is more "last element"-like then an exception object.

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

If you want to inspect html, css or maybe you need js console in your mobile browser . You can use excelent tool eruda Using it you have the same Developer Tools on your mobile browser like in your desctop device. Dont forget to upvote :) Here is a link https://github.com/liriliri/eruda
