The most effective debugging tool is still careful thought, coupled with judiciously placed print statements.

I am posting my solution too, used for an ASP.NET FileUpload control. Perhaps someone will find it useful.

    $(function () {        
    $('<%= fileUploadCV.ClientID %>').change(function () {

        //because this is single file upload I use only first index
        var f = this.files[0]

        //here I CHECK if the FILE SIZE is bigger than 8 MB (numbers below are in bytes)
        if (f.size > 8388608 || f.fileSize > 8388608)
        {
           //show an alert to the user
           alert("Allowed file size exceeded. (Max. 8 MB)")

           //reset file upload control
           this.value = null;
        }
    })
});

In C++ the stack memory is where local variables get stored/constructed. The stack is also used to hold parameters passed to functions.

The stack is very much like the std::stack class: you push parameters onto it and then call a function. The function then knows that the parameters it expects can be found on the end of the stack. Likewise, the function can push locals onto the stack and pop them off it before returning from the function. (caveat - compiler optimizations and calling conventions all mean things aren't this simple)

The stack is really best understood from a low level and I'd recommend Art of Assembly - Passing Parameters on the Stack. Rarely, if ever, would you consider any sort of manual stack manipulation from C++.

Generally speaking, the stack is preferred as it is usually in the CPU cache, so operations involving objects stored on it tend to be faster. However the stack is a limited resource, and shouldn't be used for anything large. Running out of stack memory is called a Stack buffer overflow. It's a serious thing to encounter, but you really shouldn't come across one unless you have a crazy recursive function or something similar.

Heap memory is much as rskar says. In general, C++ objects allocated with new, or blocks of memory allocated with the likes of malloc end up on the heap. Heap memory almost always must be manually freed, though you should really use a smart pointer class or similar to avoid needing to remember to do so. Running out of heap memory can (will?) result in a std::bad_alloc.

splattne,

@VonC solution partly works but there is some issue if the tag had a mixed of unquoted and quoted

This one works with mixed attributes

$pat_attributes = "(\S+)=(\"|'| |)(.*)(\"|'| |>)"

to test it out

<?php
$pat_attributes = "(\S+)=(\"|'| |)(.*)(\"|'| |>)"

$code = '    <IMG title=09.jpg alt=09.jpg src="http://example.com.jpg?v=185579" border=0 mce_src="example.com.jpg?v=185579"
    ';

preg_match_all( "@$pat_attributes@isU", $code, $ms);
var_dump( $ms );

$code = '
<a href=test.html class=xyz>
<a href="test.html" class="xyz">
<a href=\'test.html\' class="xyz">
<img src="http://"/>      ';

preg_match_all( "@$pat_attributes@isU", $code, $ms);

var_dump( $ms );

$ms would then contain keys and values on the 2nd and 3rd element.

$keys = $ms[1];
$values = $ms[2];

I got same error while running JAVA command. To resolve this, I moved the java path as the first entry in the path, and it resolved the issue. Please have look at this screenshot for reference:

You're missing a FROM and you need to give the subquery an alias.

SELECT COUNT(*) FROM 
(
  SELECT DISTINCT a.my_id, a.last_name, a.first_name, b.temp_val
   FROM dbo.Table_A AS a 
   INNER JOIN dbo.Table_B AS b 
   ON a.a_id = b.a_id
) AS subquery;

You could store the data in an array of strings of some large fixed size. It should be efficient to access any particular character in that array of strings, and to treat that character as a byte.

It would be interesting to see the operations you want to support, perhaps expressed as an interface, to make the question more concrete.

You can use DESCRIBE:

DESCRIBE my_table;

Or in newer versions you can use INFORMATION_SCHEMA:

SELECT COLUMN_NAME
  FROM INFORMATION_SCHEMA.COLUMNS
  WHERE TABLE_SCHEMA = 'my_database' AND TABLE_NAME = 'my_table';

Or you can use SHOW COLUMNS:

SHOW COLUMNS FROM my_table;

Or to get column names with comma in a line:

SELECT group_concat(COLUMN_NAME)
  FROM INFORMATION_SCHEMA.COLUMNS
  WHERE TABLE_SCHEMA = 'my_database' AND TABLE_NAME = 'my_table';

For selecting all in visual: Type Esc to be sure yor are in normal mode

:0 

type ENTER to go to the beginning of file

This isn't published on Arduino.cc but you can in fact exit from the loop routine with a simple exit(0);

This will compile on pretty much any board you have in your board list. I'm using IDE 1.0.6. I've tested it with Uno, Mega, Micro Pro and even the Adafruit Trinket

void loop() {
// All of your code here

/* Note you should clean up any of your I/O here as on exit, 
all 'ON'outputs remain HIGH */

// Exit the loop 
exit(0);  //The 0 is required to prevent compile error.
}

I use this in projects where I wire in a button to the reset pin. Basically your loop runs until exit(0); and then just persists in the last state. I've made some robots for my kids, and each time the press a button (reset) the code starts from the start of the loop() function.

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

SOAP is an ill-suited technology for use on Android (or mobile devices in general) because of the processing/parsing overhead that's required. A REST services is a lighter weight solution and that's what I would suggest. Android comes with a SAX parser, and it's fairly trivial to use. If you are absolutely required to handle/parse SOAP on a mobile device then I feel sorry for you, the best advice I can offer is just not to use SOAP.

Shahar's answer was really helpful, but I found it quite tedious to do this all myself, so I made a nifty little Python program:

import re
import urllib2
import string
url1 = raw_input("Please enter a URL from Tunein Radio: ");
open_file = urllib2.urlopen(url1);
raw_file = open_file.read();
API_key = re.findall(r"StreamUrl\":\"(.*?),",raw_file);
#print API_key;
#print "The API key is: " + API_key[0];
use_key = urllib2.urlopen(str(API_key[0]));
key_content = use_key.read();
raw_stream_url = re.findall(r"Url\": \"(.*?)\"",key_content);
bandwidth = re.findall(r"Bandwidth\":(.*?),", key_content);
reliability = re.findall(r"lity\":(.*?),", key_content);
isPlaylist = re.findall(r"HasPlaylist\":(.*?),",key_content);
codec = re.findall(r"MediaType\": \"(.*?)\",", key_content);
tipe = re.findall(r"Type\": \"(.*?)\"", key_content);
total = 0
for element in raw_stream_url:
    total = total + 1
i = 0
print "I found " + str(total) + " streams.";
for element in raw_stream_url:
    print "Stream #" + str(i + 1);
    print "Stream stats:";
    print "Bandwidth: " + str(bandwidth[i]) + " kilobytes per second."
    print "Reliability: " + str(reliability[i]) + "%"
    print "HasPlaylist: " + str(isPlaylist[i]) + "."
    print "Stream codec: " + str(codec[i]) + "."
    print "This audio stream is " + tipe[i].lower() + "."
    print "Pure streaming URL: " + str(raw_stream_url[i]) + ".";
    i = i + 1
raw_input("Press enter to close TMUS.")

It's basically Shahar's solution automated.

Posting it from my project.

<select name="parent" id="parent"><option value="0">None</option>
<?php
 $select="select=selected";
 $allparent=mysql_query("select * from tbl_page_content where parent='0'");
 while($parent=mysql_fetch_array($allparent))
   {?>
   <option value="<?= $parent['id']; ?>" <?php if( $pageDetail['parent']==$parent['id'] ) { echo($select); }?>><?= $parent['name']; ?></option>
  <?php 
   }
  ?></select>

None of these options show up for me. The way to paste data from Excel is as follows:

• Add an extra column to the left of your spreadsheet data (if you don't have row numbers showing in PL/SQL Developer you may not have to have an extra empty column to the left).

• Copy the rows of data from your spreadsheet including the empty column.

• In PL/SQL Developer, open your table in edit mode. You can right-click the table name in the object browser and select Edit Data or write your own select statement that includes the rowid and click the lock icon. Be sure your columns are ordered the same as in your spreadsheet.

• Here's the part that took me forever to figure out: click on the left side of the first empty row to highlight it. It will not work if you don't have the first empty row highlighted.

• Paste as usual using Ctrl+V or right-click Paste.

I couldn't find this info anywhere when I needed it, so I wanted to be sure to post it.

In my opinion you should not load and use plugins you don't have to. This particular jQuery plugin doesn't give you anything since directly using the JavaScript sessionStorage object is exactly the same level of complexity. Nor, does the plugin provide some easier way to interact with other jQuery functionality. In addition the practice of using a plugin discourages a deep understanding of how something works. sessionStorage should be used only if its understood. If its understood, then using the jQuery plugin is actually MORE effort.

Consider using sessionStorage directly: https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#sessionStorage

This a variant of Igor Ostroumov's answer:

If you would like to use it as a default value for a parameter, you need to consider a second level call to 'caller':

function getFunctionsNameThatCalledThisFunction()
{
  return getFunctionsNameThatCalledThisFunction.caller.caller.name;
}

This would dynamically allow for a reusable implementation in multiple functions.

function getFunctionsNameThatCalledThisFunction()_x000D_
{_x000D_
  return getFunctionsNameThatCalledThisFunction.caller.caller.name;_x000D_
}_x000D_
_x000D_
function bar(myFunctionName = getFunctionsNameThatCalledThisFunction())_x000D_
{ _x000D_
  alert(myFunctionName);_x000D_
}_x000D_
_x000D_
// pops-up "foo"_x000D_
function foo()_x000D_
{_x000D_
  bar();_x000D_
}_x000D_
_x000D_
function crow()_x000D_
{_x000D_
  bar();_x000D_
}_x000D_
_x000D_
foo();_x000D_
crow();

If you want the file name too, here is that solution using the answer from F-3000 on another question:

function getCurrentFileName()
{
  let currentFilePath = document.scripts[document.scripts.length-1].src 
  let fileName = currentFilePath.split('/').pop() // formatted to the OP's preference

  return fileName 
}

function bar(fileName = getCurrentFileName(),  myFunctionName = getFunctionsNameThatCalledThisFunction())
{
  alert(fileName + ' : ' + myFunctionName);
}

// or even better: "myfile.js : foo"
function foo()
{
  bar();
}

If you really want to dive into it and even need to distinguish between -0 and 0, here's a way to do it.

function negative(number) {
  return !Object.is(Math.abs(number), +number);
}

console.log(negative(-1));  // true
console.log(negative(1));   // false
console.log(negative(0));   // false
console.log(negative(-0));  // true

You can try :

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" >

Just like you tried before, but caution:

It seems like the X-UA-Compatible tag has to be the first tag in the < head > section

If this conclusion is correct, then I believe it is undocumented in Microsoft’s blogs/msdn (and if it is documented, then it isn’t sticking out well enough from the docs). Ensuring that this was the first meta tag in the forced IE9 to switch to IE8 mode successfully

For prototyping, using curl from the shell with the -m parameter allow to pass milliseconds, and will work in both cases, either the connection didn't initiate, error 404, 500, bad url, or the whole data wasn't retrieved in full in the allowed time range, the timeout is always effective. Php won't ever hang out.

Simply don't pass unsanitized user data in the shell call.

system("curl -m 50 -X GET 'https://api.kraken.com/0/public/OHLC?pair=LTCUSDT&interval=60' -H  'accept: application/json' > data.json");
// This data had been refreshed in less than 50ms
var_dump(json_decode(file_get_contents("data.json"),true));

I would recommend the read_csv function from the pandas library:

import pandas as pd
df=pd.read_csv('myfile.csv', sep=',',header=None)
df.values
array([[ 1. ,  2. ,  3. ],
       [ 4. ,  5.5,  6. ]])

This gives a pandas DataFrame - allowing many useful data manipulation functions which are not directly available with numpy record arrays.

DataFrame is a 2-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or SQL table...

I would also recommend genfromtxt. However, since the question asks for a record array, as opposed to a normal array, the dtype=None parameter needs to be added to the genfromtxt call:

Given an input file, myfile.csv:

1.0, 2, 3
4, 5.5, 6

import numpy as np
np.genfromtxt('myfile.csv',delimiter=',')

gives an array:

array([[ 1. ,  2. ,  3. ],
       [ 4. ,  5.5,  6. ]])

and

np.genfromtxt('myfile.csv',delimiter=',',dtype=None)

gives a record array:

array([(1.0, 2.0, 3), (4.0, 5.5, 6)], 
      dtype=[('f0', '<f8'), ('f1', '<f8'), ('f2', '<i4')])

This has the advantage that file with multiple data types (including strings) can be easily imported.

Tried several different commands until I came across:

source venv/Scripts/activate

This did it for me. Setup: Win 10, python 3.7, gitbash. Gitbash might be the culprit for not playing nice with other activate commands.

Here is the solution , follow the below link Step by Step :

In my case following code was a problem:

entityManager.detach(topicById);
topicById.getComments() // exception thrown

Because it detached from the database and Hibernate no longer retrieved list from the field when it was needed. So I initialize it before detaching:

Hibernate.initialize(topicById.getComments());
entityManager.detach(topicById);
topicById.getComments() // works like a charm

The Invalidate() Method will cause a repaint.

It worked for me, but the exe4j can leave a signature when you double click the .exe application

<input name='id[]' type='checkbox' value='".$shopnumb."\'>
<input name='id[]' type='checkbox' value='".$shopnumb."\'>
<input name='id[]' type='checkbox' value='".$shopnumb."\'>


$id = implode(',',$_POST['id']);
echo $id

you cannot echo an array because it will just print out Array. If you wanna print out an array use print_r.

print_r($_POST['id']);

In my config/application.yml I have changed this

redis:
    url: "redis://redis:6379/0"

to this

redis:

...We don't have a newer version of MySQL yet, so I was able to do this (works only on UNIX):

 host=maindb

 echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Locked

The above will query for all locked sessions, and return the information and SQL that is involved.

...So- assuming you wanted to query for sessions that were sleeping:

  host=maindb

  echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Sleep

Or, assuming you needed to provide additional connection parameters for MySQL:

  host=maindb

  user=me

  echo "show full processlist\G" | mysql -h$host -u$user -p$password | grep -B 6 -A 1 Locked

With a couple of tweaks, I'm sure a shell script could be easily created to query the processlist the way you want it.

Flask-Sqlalchemy

Delete All Records

#for all records
db.session.query(Model).delete()
db.session.commit()

Deleted Single Row

here DB is the object Flask-SQLAlchemy class. It will delete all records from it and if you want to delete specific records then try filter clause in the query. ex.

#for specific value
db.session.query(Model).filter(Model.id==123).delete()
db.session.commit()

Delete Single Record by Object

record_obj = db.session.query(Model).filter(Model.id==123).first()
db.session.delete(record_obj)
db.session.commit()

The maximum value that a Java Integer can handle is 2147483657, or 2^31-1. The hexadecimal number AA0F245C is 2853119068 as a decimal number, and is far too large, so you need to use

Long.parseLong("AA0F245C", 16);

to make it work.

This is how I've "handled" it if you use pluck to get an identifier for each of the records, join the arrays together and then finally do a query for those joined ids:

  transaction_ids = @club.type_a_trans.pluck(:id) + @club.type_b_transactions.pluck(:id) + @club.type_c_transactions.pluck(:id)
  @transactions = Transaction.where(id: transaction_ids).limit(100)

Since it's a long time and people keep suggesting to use Scanner#nextLine(), there's another chance that Scanner can take spaces included in input.

Class Scanner

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.

You can use Scanner#useDelimiter() to change the delimiter of Scanner to another pattern such as a line feed or something else.

Scanner in = new Scanner(System.in);
in.useDelimiter("\n"); // use LF as the delimiter
String question;

System.out.println("Please input question:");
question = in.next();

// TODO do something with your input such as removing spaces...

if (question.equalsIgnoreCase("howdoyoulikeschool?") )
    /* it seems strings do not allow for spaces */
    System.out.println("CLOSED!!");
else
    System.out.println("Que?");

Cern's ROOT produces some pretty nice stuff, I use it to display Neural Network data a lot.

I had the same problem. If you try to upload an image that is too large on some low resolution devices, the app will collapse. You can make several images of different sizes (hdpi, xxdpi and more) or simply use an external library to load images that solve the problem quickly and efficiently. I used Glide library (you can use another library like Picasso).

    panel_IMG_back = (ImageView) findViewById(R.id.panel_IMG_back);
    Glide
            .with(this)
            .load(MyViewUtils.getImage(R.drawable.wallpaper)
            .into(panel_IMG_back);

I actually wouldn't recommend using a2enmod for php 5 or 7. I would use update-alternatives. You can do sudo update-alternatives --config php to set which system wide version of PHP you want to use. This makes your command line and apache versions work the same. You can read more about update-alternatives on the man page.

To export db rather it is SQLITE or ROOM:

Firstly, add this permission in AndroidManifest.xml file:

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

Secondly, we drive to code the db functions:

private void exportDB() {
    try {
        File dbFile = new File(this.getDatabasePath(DATABASE_NAME).getAbsolutePath());
        FileInputStream fis = new FileInputStream(dbFile);

        String outFileName = DirectoryName + File.separator +
                DATABASE_NAME + ".db";

        // Open the empty db as the output stream
        OutputStream output = new FileOutputStream(outFileName);

        // Transfer bytes from the inputfile to the outputfile
        byte[] buffer = new byte[1024];
        int length;
        while ((length = fis.read(buffer)) > 0) {
            output.write(buffer, 0, length);
        }
        // Close the streams
        output.flush();
        output.close();
        fis.close();


    } catch (IOException e) {
        Log.e("dbBackup:", e.getMessage());
    }
}

    boolean success = true;
    if (!folder.exists()) {

wininet.dll returns both standard and non-standard status codes that are listed below.

401 - Unauthorized file
403 - Forbidden file
404 - File Not Found
500 - some inclusion or functions may missed
200 - Completed

12002 - Server timeout
12029,12030, 12031 - dropped connections (either web server or DB server)
12152 - Connection closed by server.
13030 - StatusText properties are unavailable, and a query attempt throws an exception

For the status code "zero" are you trying to do a request on a local webpage running on a webserver or without a webserver?

XMLHttpRequest status = 0 and XMLHttpRequest statusText = unknown can help you if you are not running your script on a webserver.

Our DMS Software Reengineering Toolkit has static control/dataflow/points-to/call graph analysis that has been applied to huge systems (~~25 million lines) of C code, and produced such call graphs, including functions called via function pointers.

Since search engines ignore most javascript, you will need to make it so that search engines can crawl using the tabs without using Ajax. Make each tab a link with an href that loads the entire page with that tab selected. Then the page can have that title in the tag.

The onclick event handler can still load the pages via ajax for human viewers.

To see the pages as most search engines see them, turn off Javascript in your browser, and try to make it so that clicking the tabs will load the page with that tab selected and the correct title.

If you are loading via ajax and you want to dynamically change the page title with just Javascript, then do:

document.title = 'Put the new title here';

However, search engines will not see this change made in javascript.

Hibernate does not allow for specifying time zones by annotation or any other means. If you use Calendar instead of date, you can implement a workaround using HIbernate property AccessType and implementing the mapping yourself. The more advanced solution is to implement a custom UserType to map your Date or Calendar. Both solutions are explained in my blog post here: http://www.joobik.com/2010/11/mapping-dates-and-time-zones-with.html

One way to get this error is trying to add a usercontrol to a form while the project is set to compile as x64. Visual Studio throws the unhelpful: "Failed to load toolbox item . It will be removed from the toolbox."

Workaround is to design with "Any CPU" and compile to x64 as necessary.

System.out.println("Element "+i+list.get(0));}

Should be

System.out.println("Element "+i+list.get(i));}

To use the JSF tags, you give the dataList value attribute a reference to your list of elements, and the var attribute is a local name for each element of that list in turn. Inside the dataList, you use properties of the object (getters) to output the information about that individual object:

<t:dataList id="myDataList" value="#{houseControlList}" var="element" rows="3" >
...
<t:outputText id="houseId" value="#{element.houseId}"/>
...
</t:dataList>

I had Java 1.8 but had to downgrade to Java 1.6 for some reason. When I uninstalled java 1.8 and ran the command "Java -Version" from the command prompt, I got the error -

Error: Registry key 'Software\JavaSoft\Java Runtime Environment'\CurrentVersion'

has value '1.6', but '1.8' is required. Error: could not find java.dll Error: Could not find Java SE Runtime Environment.

Uninstalling 1.6 and then reinstalling 1.6 fixed the issue for me :-)

If using eclipse to deploy your application . We can use this maven plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-eclipse-plugin</artifactId>
    <version>2.10</version>
    <configuration>
        <wtpversion>2.0</wtpversion>
        <wtpContextName>newContextroot</wtpContextName>
    </configuration>
</plugin>

now go to your project root folder and open cmd prompt at that location type this command :

mvn eclipse:eclipse -Dwtpversion=2.0

You may need to restart eclipse , or in server view delete server and create agian to see affect. I wonder this exercise make sense in real life but works.

In Linux Mint 18 Cinnamon be sure to check /etc/profile.d/jdk_home.sh I renamed this file to jdk_home.sh.old and now my path does not keep getting overridden and I can call java -version and see Java 9 as expected. Even though I correctly selected Java 9 in update-aternatives --config java this jdk_home.sh file kept overriding the $PATH on boot-up.

Quick answer: change int testlib() to int testlib(void) to specify that the function takes no arguments.

A prototype is by definition a function declaration that specifies the type(s) of the function's argument(s).

A non-prototype function declaration like

int foo();

is an old-style declaration that does not specify the number or types of arguments. (Prior to the 1989 ANSI C standard, this was the only kind of function declaration available in the language.) You can call such a function with any arbitrary number of arguments, and the compiler isn't required to complain -- but if the call is inconsistent with the definition, your program has undefined behavior.

For a function that takes one or more arguments, you can specify the type of each argument in the declaration:

int bar(int x, double y);

Functions with no arguments are a special case. Logically, empty parentheses would have been a good way to specify that an argument but that syntax was already in use for old-style function declarations, so the ANSI C committee invented a new syntax using the void keyword:

int foo(void); /* foo takes no arguments */

A function definition (which includes code for what the function actually does) also provides a declaration. In your case, you have something similar to:

int testlib()
{
    /* code that implements testlib */
}

This provides a non-prototype declaration for testlib. As a definition, this tells the compiler that testlib has no parameters, but as a declaration, it only tells the compiler that testlib takes some unspecified but fixed number and type(s) of arguments.

If you change () to (void) the declaration becomes a prototype.

The advantage of a prototype is that if you accidentally call testlib with one or more arguments, the compiler will diagnose the error.

(C++ has slightly different rules. C++ doesn't have old-style function declarations, and empty parentheses specifically mean that a function takes no arguments. C++ supports the (void) syntax for consistency with C. But unless you specifically need your code to compile both as C and as C++, you should probably use the () in C++ and the (void) syntax in C.)

You don't need a regex for this one. Use the isNAN() JavaScript function.

The isNaN() function determines whether a value is an illegal number (Not-a-Number). This function returns true if the value is NaN, and false if not.

if (isNaN($('#Field').val()) == false) {

    // It's a number
}

You can use the .position() for this

var link = $(element);
var position = link.position(); //cache the position
var right = $(window).width() - position.left - link.width();
var bottom = $(window).height() - position.top - link.height();

The viewBox isn't the height of the container, it's the size of your drawing. Define your viewBox to be 100 units in width, then define your rect to be 10 units. After that, however large you scale the SVG, the rect will be 10% the width of the image.

I have some problem when there are two lists and second one is inside DIV Second list should start at 1. not 2.1

EDIT: I solved the problem by this http://jsfiddle.net/hy5f6161/

if(view instanceof B)

This will return true if view is an instance of B or the subclass A (or any subclass of B for that matter).

private void fillTextView (int id, String text) {
    TextView tv = (TextView) findViewById(id);
    tv.setText(text);
}

If this is where you're getting the null pointer exception, there was no view found for the id that you passed into findViewById(), and the actual exception is thrown when you try to call a function setText() on null. You should post your XML for R.layout.activity_main, as it's hard to tell where things went wrong just by looking at your code.

More reading on null pointers: What is a NullPointerException, and how do I fix it?

You can use:

set content=
for /f "delims=" %%i in ('type text.txt') do set content=!content! %%i

You can write your own equals function:

• dicts are equal if: 1) all keys are equal, 2) all values are equal
• lists are equal if: all items are equal and in the same order
• primitives are equal if a == b

Because you're dealing with json, you'll have standard python types: dict, list, etc., so you can do hard type checking if type(obj) == 'dict':, etc.

Rough example (not tested):

def json_equals(jsonA, jsonB):
    if type(jsonA) != type(jsonB):
        # not equal
        return False
    if type(jsonA) == dict:
        if len(jsonA) != len(jsonB):
            return False
        for keyA in jsonA:
            if keyA not in jsonB or not json_equal(jsonA[keyA], jsonB[keyA]):
                return False
    elif type(jsonA) == list:
        if len(jsonA) != len(jsonB):
            return False
        for itemA, itemB in zip(jsonA, jsonB):
            if not json_equal(itemA, itemB):
                return False
    else:
        return jsonA == jsonB

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

There's no built-in way, you'll have to loop over all of them:

function setAll(a, v) {
    var i, n = a.length;
    for (i = 0; i < n; ++i) {
        a[i] = v;
    }
}

http://jsfiddle.net/alnitak/xG88A/

If you really want, do this:

Array.prototype.setAll = function(v) {
    var i, n = this.length;
    for (i = 0; i < n; ++i) {
        this[i] = v;
    }
};

and then you could actually do cool.setAll(42) (see http://jsfiddle.net/alnitak/ee3hb/).

Some people frown upon extending the prototype of built-in types, though.

EDIT ES5 introduced a way to safely extend both Object.prototype and Array.prototype without breaking for ... in ... enumeration:

Object.defineProperty(Array.prototype, 'setAll', {
    value: function(v) {
        ...
    }
});

EDIT 2 In ES6 draft there's also now Array.prototype.fill, usage cool.fill(42)

You can also extract the event code from the HTML, like this :

<input type="checkbox" id="check_all_1" name="check_all_1" title="Select All" />
<label for="check_all_1">Select All</label>

<script>
function selectAll(frmElement, chkElement) {

document.getElementById("check_all_1").onclick = function() {
    selectAll(document.wizard_form, this);
}
</script>

I was experiencing this error on Android 5.1.1 devices sending network requests using okhttp/4.0.0-RC1. Setting header Content-Length: <sizeof response> on the server side resolved the issue.

Try this:

String yourVal = "20.5";
float a = (Float.valueOf(yourVal)).floatValue(); 
System.out.println(a);

So, the trick here is to use absolute positioning calc like this:

top: calc(50% - XYpx);
left: calc(50% - XYpx);

where XYpx is half the size of your image, in my case, the image was a square. Of course, in this now obsolete case, the image must also change its size proportionally in response to window resize to be able to remain at the center without looking out of proportion.

Add the MessageUI.Framework and use the following code

#import <MessageUI/MessageUI.h> 

And then:

if ([MFMessageComposeViewController canSendText]) {
  MFMessageComposeViewController *messageComposer =
  [[MFMessageComposeViewController alloc] init];
  NSString *message = @"Your Message here";
  [messageComposer setBody:message];
  messageComposer.messageComposeDelegate = self;
  [self presentViewController:messageComposer animated:YES completion:nil];
}

and the delegate method -

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller
             didFinishWithResult:(MessageComposeResult)result {
      [self dismissViewControllerAnimated:YES completion:nil];
 }

Since iOS 8, you can't, it doesn't work because Apple changed internal implementation of UIActionSheet. Please refer to Apple Documentation:

Subclassing Notes

UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.

Try with below code.

Like GridView in LinkButton, Label, HtmlAnchor and HtmlInputControl.

    <Columns>
        <asp:TemplateField HeaderText="HeaderName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
            <ItemTemplate>
                <asp:Label runat="server" ID="lblName" Text=' <%# Eval("LabelName") %>'></asp:Label>
                <asp:LinkButton ID="btnLink" runat="server">ButtonName</asp:LinkButton>
                <a href="javascript:void(0);" id="btnAnchor" runat="server">ButtonName</a>
                <input type="hidden" runat="server" id="hdnBtnInput" value='<%#Eval("ID") %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Handling RowDataBound event,

protected void mainGrid_RowDataBound(object sender, GridViewRowEventArgs e)

    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Label lblName = (Label)e.Row.FindControl("lblName");
        LinkButton btnLink = (LinkButton)e.Row.FindControl("btnLink");
        HtmlAnchor btnAnchor = (HtmlAnchor)e.Row.FindControl("btnAnchor");
        HtmlInputControl hdnBtnInput = (HtmlInputControl)e.Row.FindControl("hdnBtnInput");
    }
}

worked for me:

AVG(CASE WHEN SecurityW <> 0 THEN SecurityW ELSE NULL END)

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

I use RegexBuddy for debbuging my regexes it has almost all languages very usefull. Than copy/paste for the targeted language. Terrific tool and not very expensive.

So I copy/pasted your regex and your issue is that [,] are special characters in regex, so you need to escape them. So the regex should be : /!@#$^&%*()+=-[\x5B\x5D]\/{}|:<>?,./im

Tried all the solutions above but none of them worked for me. What did work was I uninstalling .NET versions > 4.5, including all its multilingual versions; Eventually I added newer (English only) versions piece by piece. Right now versions installed on my system is this:

• 2.0
• 3.0
• 3.5 4
• 4.5
• 4.5.1
• 4.5.2
• 4.6
• 4.6.1

And its still working at this point. I'm afraid to install 4.6.2 because it might mess everything up.

So I could only speculate that either 4.6.2 or all those non-English versions were messing up my configuration.

If you want the display dimensions in pixels you can use getSize:

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;

If you're not in an Activity you can get the default Display via WINDOW_SERVICE:

WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();

If you are in a fragment and want to acomplish this just use Activity.WindowManager (in Xamarin.Android) or getActivity().getWindowManager() (in java).

Before getSize was introduced (in API level 13), you could use the getWidth and getHeight methods that are now deprecated:

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();  // deprecated
int height = display.getHeight();  // deprecated

For the use case you're describing however, a margin/padding in the layout seems more appropriate.

Another way is: DisplayMetrics

A structure describing general information about a display, such as its size, density, and font scaling. To access the DisplayMetrics members, initialize an object like this:

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);

We can use widthPixels to get information for:

"The absolute width of the display in pixels."

Example:

Log.d("ApplicationTagName", "Display width in px is " + metrics.widthPixels);

Api level 30 update

final WindowMetrics metrics = windowManager.getCurrentWindowMetrics();
 // Gets all excluding insets
 final WindowInsets windowInsets = metrics.getWindowInsets();
 Insets insets = windowInsets.getInsetsIgnoreVisibility(WindowInsets.Type.navigationBars()
         | WindowInsets.Type.displayCutout());

 int insetsWidth = insets.right + insets.left;
 int insetsHeight = insets.top + insets.bottom;

 // Legacy size that Display#getSize reports
 final Rect bounds = metrics.getBounds();
 final Size legacySize = new Size(bounds.width() - insetsWidth,
         bounds.height() - insetsHeight);

Does it have to be String.Format?

This looks like a job for String.Padleft

myString=myString.PadLeft(3, '0');

Or, if you are converting direct from an int:

myInt.toString("D3");

Using sindresorhus's fkill tool, you can do this:

$ fkill :3000

Based on dominic Rodger's solution, here is what I use (it uses wc if available, otherwise fallbacks to dominic Rodger's solution).

class FileTool

        $linecount = 0;

        $m = exec('which wc');
        if ('' !== $m) {
            $cmd = 'wc -l < "' . str_replace('"', '\\"', $file) . '"';

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

Use named parameters for readability and to avoid confusions.

@Html.ActionLink(
            linkText: "Click Here",
            actionName: "Action",
            controllerName: "Home",
            routeValues: new { Identity = 2577 },
            htmlAttributes: null)

Would something like this work:

In [7]: df.groupby('dummy').returns.agg({'func1' : lambda x: x.sum(), 'func2' : lambda x: x.prod()})
Out[7]: 
              func2     func1
dummy                        
1     -4.263768e-16 -0.188565

Since 2011a, the recommended way is:

booleanIndex = strcmp('KU', strs)

If you want to get the integer index (which you often don't need), you can use:

integerIndex = find(booleanIndex);

strfind is deprecated, so try not to use it.

I think easiest way to see final query text when you use pdo is to make special error and look error message. I don't know how to do that, but when i make sql error in yii framework that use pdo i could see query text

I kept receiving the same message no matter what i did.

To fix this, i removed .gitignore and i am not getting the Github changes not staged for commit message anymore. Before it would allow me to commit once when i ran git add . and then after it would bring up the same message.

Im not sure why the .gitignore file was causing a problem but i added on my local machine and most likely didn't sync it up properly.

It's look like you are using an old version of slim(2.x). You can just add following lines to .htaccess and don't need to do anything in PHP scripts.

# Enable cross domain access control
SetEnvIf Origin "^http(s)?://(.+\.)?(domain_one\.com|domain_two\.net)$" REQUEST_ORIGIN=$0
Header always set Access-Control-Allow-Origin %{REQUEST_ORIGIN}e env=REQUEST_ORIGIN
Header always set Access-Control-Allow-Methods "GET, POST, PUT, DELETE"
Header always set Access-Control-Allow-Headers: Authorization

# Force to request 200 for options
RewriteEngine On
RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule .* / [R=200,L]

lines is a list of strings, re.findall doesn't work with that. try:

import re, sys

f = open('findallEX.txt', 'r')
lines = f.read()
match = re.findall('[A-Z]+', lines)
print match

The SQL Server Management Studio has implicit commit turned on, so all statements that are executed are implicitly commited.

This might be a scary thing if you come from an Oracle background where the default is to not have commands commited automatically, but it's not that much of a problem.

If you still want to use ad-hoc transactions, you can always execute

BEGIN TRANSACTION

within SSMS, and than the system waits for you to commit the data.

If you want to replicate the Oracle behaviour, and start an implicit transaction, whenever some DML/DDL is issued, you can set the SET IMPLICIT_TRANSACTIONS checkbox in

Tools -> Options -> Query Execution -> SQL Server -> ANSI

Seems like only real solutions today revolve around scaling out or sharding. All modern databases (NoSQLs as well as NewSQLs) support horizontal scaling right out of the box, at the database layer, without the need for the application to have sharding code or something.

Unfortunately enough, for the trusted good-old MySQL, sharding is not provided "out of the box". ScaleBase (disclaimer: I work there) is a maker of a complete scale-out solution an "automatic sharding machine" if you like. ScaleBae analyzes your data and SQL stream, splits the data across DB nodes, and aggregates in runtime – so you won’t have to! And it's free download.

Don't get me wrong, NoSQLs are great, they're new, new is more choice and choice is always good!! But choosing NoSQL comes with a price, make sure you can pay it...

You can see here some more data about MySQL, NoSQL...: http://www.scalebase.com/extreme-scalability-with-mongodb-and-mysql-part-1-auto-sharding

Hope that helped.

also you can try in your servce to set headers like for example:

...
import { Injectable } from "@angular/core";
import { HttpClient, HttpHeaders, HttpParams } from "@angular/common/http";
...
 @Injectable()
export class MyService {

    private headers: HttpHeaders;


    constructor(private http: HttpClient..) 
    {


        this.headers = new HttpHeaders()
                    .append("Content-Type", "application/json")
                    .append("Accept", "application/json")
                    .append("LanguageCulture", this.headersLanguage)
                    .append("Cache-Control", "no-cache")
                    .append("Pragma", "no-cache")                   
    }
}
....

For windows, unix, or Mac? On the Mac or *nix you can use command line or GUI versions of emacs or vim.

For the Mac: TextWrangler to handle big files well. I'm not versed enough on the Windows landscape to help out there.

In Bootstrap 3 they do not have separate classes for different styles of labels.

http://getbootstrap.com/components/

However, you can customize bootstrap classes that way. In your css file

.lb-sm {
  font-size: 12px;
}

.lb-md {
  font-size: 16px;
}

.lb-lg {
  font-size: 20px;
}

Alternatively, you can use header tags to change the sizes. For example, here is a medium sized label and a small-sized label

<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<h3>Example heading <span class="label label-default">New</span></h3>_x000D_
<h6>Example heading <span class="label label-default">New</span></h6>

They might add size classes for labels in future Bootstrap versions.

Minted, whether from GitHub or CTAN, the Comprehensive TeX Archive Network, works in Overleaf, TeX Live and MiKTeX.

It requires the installation of the Python package Pygments; this is explained in the documentation in either source above. Although Pygments brands itself as a Python syntax highlighter, Minted guarantees the coverage of hundreds of other languages.

Example:

\documentclass{article}
\usepackage{minted}
\begin{document}

\begin{minted}[mathescape, linenos]{python}

# Note: $\pi=\lim_{n\to\infty}\frac{P_n}{d}$
title = "Hello World"

sum = 0
for i in range(10):
 sum += i

\end{minted}

\end{document}

Output:

Many algorithms will specify that duplicates are excluded. For example, the example algorithms in the MIT Algorithms book usually present examples without duplicates. It is fairly trivial to implement duplicates (either as a list at the node, or in one particular direction.)

Most (that I've seen) specify left children as <= and right children as >. Practically speaking, a BST which allows either of the right or left children to be equal to the root node, will require extra computational steps to finish a search where duplicate nodes are allowed.

It is best to utilize a list at the node to store duplicates, as inserting an '=' value to one side of a node requires rewriting the tree on that side to place the node as the child, or the node is placed as a grand-child, at some point below, which eliminates some of the search efficiency.

You have to remember, most of the classroom examples are simplified to portray and deliver the concept. They aren't worth squat in many real-world situations. But the statement, "every element has a key and no two elements have the same key", is not violated by the use of a list at the element node.

So go with what your data structures book said!

Edit:

Universal Definition of a Binary Search Tree involves storing and search for a key based on traversing a data structure in one of two directions. In the pragmatic sense, that means if the value is <>, you traverse the data structure in one of two 'directions'. So, in that sense, duplicate values don't make any sense at all.

This is different from BSP, or binary search partition, but not all that different. The algorithm to search has one of two directions for 'travel', or it is done (successfully or not.) So I apologize that my original answer didn't address the concept of a 'universal definition', as duplicates are really a distinct topic (something you deal with after a successful search, not as part of the binary search.)

You could do this:

library(dplyr)

cols <- paste0("a", 1:10)
tab <- matrix(1:1000, nrow = 100) %>% as.tibble() %>% set_names(cols)
tab

Above I just made a dataframe with 10 columns and 100 rows, ok?

Now you can sample it with sample_n:

sample_n(tab, size = 800, replace = T)

I had similar issues and below is how i fixed it:

• Restart your PC, when booting up press f10 key to select or open BIOS Settings.
• Locate and check / enable Virtual Technology-x option under Device Configuration Settings
• Save changes, system restart.
• All should be working fine now

You could put your text in a select statement such as...

SELECT 'Querying Table1' FROM dual;

1)A primary key is a set of one or more attributes that uniquely identifies tuple within relation.

2)A foreign key is a set of attributes from a relation scheme which can be uniquely identify tuples fron another relation scheme.

Remove element should clear out such errors. The reason behind this is the inherited settings. Your application will inherit some settings from its parent's config file and machine's (server) config files.
You can either remove such duplicates with the remove tag before adding them or make these tags non-inheritable in the upper level config files.

public List<Student> findStudentByReports(Date startDate, Date endDate) {
    System.out.println("call findStudentMethd******************with this pattern"
                    + startDate
                    + endDate
                    + "*********************************************");

    return em
            .createQuery(
                    "' select attendence from Attendence attendence where attendence.admissionDate BETWEEN : startDate '' AND endDate ''"
                            + "'")
            .setParameter("startDate", startDate, TemporalType.DATE)
            .setParameter("endDate", endDate, TemporalType.DATE)
            .getResultList();

}

For me the error was resolved by stopping a virtual Ubuntu instance that'd been running in Hyper-V:

The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.

Once Ubuntu instance had been stopped, and Docker Desktop had been restarted, my usual docker commands ran just fine.

PS: I had the idea to try this because of an Error Log that Docker Desktop had helpfully compiled and offered to send to Docker Hub as user feedback... the log appeared to indicate that my machine was short on RAM, and Docker was failing for this very simple reason. Killing the Ubuntu instance solved that.

having dignosed the problem I was able to use the existing system default CA file, on debian6 this is:

/etc/ssl/certs/ca-certificates.crt

as root this can be done like:

echo curl.cainfo=/etc/ssl/certs/ca-certificates.crt >> /etc/php5/mods-available/curl.ini

then re-start the web-server.

If your button does not require a transparent background, then you can create an illusion of a border using a Frame Layout. Just adjust the FrameLayout's "padding" attribute to change the thickness of the border.

<FrameLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="1sp"
        android:background="#000000">
        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Your text goes here"
            android:background="@color/white"
            android:textColor="@color/black"
            android:padding="10sp"
            />
</FrameLayout>

I'm not sure if the shape xml files have dynamically-editable border colors. But I do know that with this solution, you can dynamically change the color of the border by setting the FrameLayout background.

Thanks to Maarten (Query a collection using PropertyInfo object in LINQ) I got this solution:

myList.OrderByDescending(x => myPropertyInfo.GetValue(x, null)).ToList();

In my case I was working on a "ColumnHeaderMouseClick" (WindowsForm) so just found the specific Column pressed and its correspondent PropertyInfo:

foreach (PropertyInfo column in (new Process()).GetType().GetProperties())
{
    if (column.Name == dgvProcessList.Columns[e.ColumnIndex].Name)
    {}
}

OR

PropertyInfo column = (new Process()).GetType().GetProperties().Where(x => x.Name == dgvProcessList.Columns[e.ColumnIndex].Name).First();

(be sure to have your column Names matching the object Properties)

Cheers

Be careful with the slash, change "\" for "/" , like this: adb.exe push SuperSU-v2.79-20161205182033.apk /storage

You should return json always, but change its status, or in following example the ResponseCode property:

if(callbackResults.ResponseCode!="200"){
    /* Some error, you can add a message too */
} else {
    /* All fine, proceed with code */
};

def import_class(cl):
    d = cl.rfind(".")
    classname = cl[d+1:len(cl)]
    m = __import__(cl[0:d], globals(), locals(), [classname])
    return getattr(m, classname)

This should do what you need

http://jsfiddle.net/7Ud6B/

As long as there are no identity columns you can just

INSERT INTO TableNew
SELECT * FROM TableOld
WHERE [Conditions]

I think that all the answers missed a crucial point:

If you use the Ajax form so that it needs to update itself (and NOT another div outside of the form) then you need to put the containing div OUTSIDE of the form. For example:

 <div id="target">
 @using (Ajax.BeginForm("MyAction", "MyController",
            new AjaxOptions
            {
                HttpMethod = "POST",
                InsertionMode = InsertionMode.Replace,
                UpdateTargetId = "target"
            }))
 {
      <!-- whatever -->
 }
 </div>

Otherwise you will end like @David where the result is displayed in a new page.

I had a domain account with a strong password, but it didn´t work, then I used Network Service account. I tried to change it on SQL Server Configuration Manager after installation and it worked.

you may use this - https://github.com/chanakyachatterjee/JSLightGrid ..JSLightGrid. have a look.. I found this one really very useful. Good performance, very light weight, all important browser friendly and fluid in itself, so you don't really need bootstrap for the grid.

I am also facing this kind of requirement.

From this discussion I got another Idea,

Obj.GetType().GetProperties()[0].Name

This is also showing the property name.

Obj.GetType().GetProperties().Count();

this showing number of properties.

Thanks to all. This is nice discussion.

It's an old question, but here are some comments...

1. In SQL, the DELETE command accepts a parameter "CASCADE", which allows you to specify that dependent objects should also be deleted. This is an example of a DELETE parameter that makes sense, but 'man rm' could provide others. How would these cases possibly be implemented in REST/HTTP without a parameter?
2. @Jan, it seems to be a well-established convention that the path part of the URL identifies a resource, whereas the querystring does not (at least not necessarily). Examples abound: getting the same resource but in a different format, getting specific fields of a resource, etc. If we consider the querystring as part of the resource identifier, it is impossible to have a concept of "different views of the same resource" without turning to non-RESTful mechanisms such as HTTP content negotiation (which can be undesirable for many reasons).

1) The reason not to prefer a shape of (R, 1) over (R,) is that it unnecessarily complicates things. Besides, why would it be preferable to have shape (R, 1) by default for a length-R vector instead of (1, R)? It's better to keep it simple and be explicit when you require additional dimensions.

2) For your example, you are computing an outer product so you can do this without a reshape call by using np.outer:

np.outer(M[:,0], numpy.ones((1, R)))

SELECT DATEADD(minute, -15, '2000-01-01 08:30:00'); 

The second value (-15 in this case) must be numeric (i.e. not a string like '00:15'). If you need to subtract hours and minutes I would recommend splitting the string on the : to get the hours and minutes and subtracting using something like

SELECT DATEADD(minute, -60 * @h - @m, '2000-01-01 08:30:00'); 

where @h is the hour part of your string and @m is the minute part of your string

EDIT:

Here is a better way:

SELECT CAST('2000-01-01 08:30:00' as datetime) - CAST('00:15' AS datetime)

Expanding on Nathans post. The following will do the job lot in one batch file.

@echo off

if %1.==Sub. goto %2

for %%f in (*.in) do call %0 Sub action %%~nf
goto end

:action
echo The file is %3
copy %3.in %3.out
ren %3.out monkeys_are_cool.txt

:end

int* arr[8]; // An array of int pointers.
int (*arr)[8]; // A pointer to an array of integers

The third one is same as the first.

The general rule is operator precedence. It can get even much more complex as function pointers come into the picture.

The ORA-01722 error is pretty straightforward. According to Tom Kyte:

We've attempted to either explicity or implicity convert a character string to a number and it is failing.

However, where the problem is is often not apparent at first. This page helped me to troubleshoot, find, and fix my problem. Hint: look for places where you are explicitly or implicitly converting a string to a number. (I had NVL(number_field, 'string') in my code.)

Add this at the start of main

ApplicationContext context = new ClassPathXmlApplicationContext("path/to/applicationContext.xml");

JobLauncher launcher=(JobLauncher)context.getBean("launcher");
Job job=(Job)context.getBean("job");

//Get as many beans you want
//Now do the thing you were doing inside test method
StopWatch sw = new StopWatch();
sw.start();
launcher.run(job, jobParameters);
sw.stop();
//initialize the log same way inside main
logger.info(">>> TIME ELAPSED:" + sw.prettyPrint());

I use for enter su mode in abd shell

adb shell "su"

Other answers are over complicating things. This question is simply logic question. Just get your statement right.

$boolString = 'false';
$result = 'true' === $boolString;

Now your answer will be either

• false, if the string was 'false',
• or true, if your string was 'true'.

I have to note that filter_var( $boolString, FILTER_VALIDATE_BOOLEAN ); still will be a better option if you need to have strings like on/yes/1 as alias for true.

There is a toJSON() method in javascript returns a string representation of the Date object. toJSON() is IE8+ and toISOString() is IE9+. Both results in YYYY-MM-DDTHH:mm:ss.sssZ format.

var date = new Date();    
    $.ajax(
       {
           type: "POST",
           url: "/Group/Refresh",
           contentType: "application/json; charset=utf-8",
           data: "{ 'MyDate': " + date.toJSON() + " }",
           success: function (result) {
               //do something
           },
           error: function (req, status, error) {
               //error                        
           }
       });

a null string is null, an empty string is ""

isNullOrEmpty requires an intimate understanding about the implementation of a string. If you want one, you can write one yourself for your object, but you have to make your own definition for whether your object is "empty" or not.

ask yourself: What does it mean for an object to be empty?

Using Now() is not a good idea. It only save the current time and date. It will not update the the current date and time, when you update your data. If you want to add the time once, The default value =Now() is best option. If you want to use timestamp. and want to update the this value, each time that row is updated. Then, trigger is best option to use.

2. http://www.tutorialspoint.com/plsql/plsql_triggers.htm

These two toturial will help to implement the trigger.

Try:

There are three ways to fetch multiple rows returned by PDO statement.

The simplest one is just to iterate over PDOStatement itself:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// iterating over a statement
foreach($stmt as $row) {
    echo $row['name'];
}

another one is to fetch rows using fetch() method inside a familiar while statement:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// using while
while($row = $stmt->fetch()) {
    echo $row['name'];
}

but for the modern web application we should have our datbase iteractions separated from output and thus the most convenient method would be to fetch all rows at once using fetchAll() method:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// fetching rows into array
$data = $stmt->fetchAll();

or, if you need to preprocess some data first, use the while loop and collect the data into array manually

$result = [];
$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// using while
while($row = $stmt->fetch()) {
    $result[] = [
        'newname' => $row['oldname'],
        // etc
    ];
}

and then output them in a template:

<ul>
<?php foreach($data as $row): ?>
    <li><?=$row['name']?></li>
<?php endforeach ?>
</ul>

Note that PDO supports many sophisticated fetch modes, allowing fetchAll() to return data in many different formats.

The answer given by Nico O is correct. However this doesn't get the desired result on Internet Explorer 10 to 11 and Firefox.

For IE, I found that changing

.flex > div
{
   flex: 1 0 50%;
}

to

.flex > div
{
   flex: 1 0 45%;
}

seems to do the trick. Don't ask me why, I haven't gone any further into this but it might have something to do with how IE renders the border-box or something.

In the case of Firefox I solved it by adding

display: inline-block;

to the items.

Like that

var purchCount = (from purchase in myBlaContext.purchases select purchase).Count();

or even easier

var purchCount = myBlaContext.purchases.Count()

You should try it like this:

var result =
        from priceLog in PriceLogList
        group priceLog by priceLog.LogDateTime.ToString("MMM yyyy") into dateGroup
        select new {
            LogDateTime = dateGroup.Key,
            AvgPrice = dateGroup.Average(priceLog => priceLog.Price)
        };

For a more detailed explanation, check out this post:

http://www.viget.com/inspire/webkit-transform-kill-the-flash/

I would definitely avoid applying it to the entire body. The key is to make sure whatever specific element you plan on transforming in the future starts out rendered in 3d so the browsers doesn't have to switch in and out of rendering modes. Adding

-webkit-transform: translateZ(0) 

(or either of the options already mentioned) to the animated element will accomplish this.

json.dumps() converts a dictionary to str object, not a json(dict) object! So you have to load your str into a dict to use it by using json.loads() method

See json.dumps() as a save method and json.loads() as a retrieve method.

This is the code sample which might help you understand it more:

import json

r = {'is_claimed': 'True', 'rating': 3.5}
r = json.dumps(r)
loaded_r = json.loads(r)
loaded_r['rating'] #Output 3.5
type(r) #Output str
type(loaded_r) #Output dict

Make's substitutions feature is nice and helped me to write

%.i: src/%.c $(INCLUDE)
        gcc -E $(CPPFLAGS) $(INCLUDE:%=-I %) $< > $@

You might find this useful, because it asks make to check for changes in include folders too

a recursive try for this

function t(k){ 
    if (k[0]==' ') {
        return t(k.substr(1,k.length));
    } else if (k[k.length-1]==' ') {
        return t(k.substr(0,k.length-1));
    } else {
        return k;
    }
}

call like this:

t("      mehmet       "); //=>"mehmet"

if you want to filter spesific chars you can define a list string basically:

function t(k){
    var l="\r\n\t "; //you can add more chars here.
    if (l.indexOf(k[0])>-1) {
        return t(k.substr(1,k.length));
    } else if (l.indexOf(k[k.length-1])>-1) {
        return t(k.substr(0,k.length-1));
    } else {
        return k;
    }
}

const object1 = {
  a: 'something',
  b: 'something',
  c: 'something'
};

const key = 's';

// Object.keys(object1) will return array of the object keys ['a', 'b', 'c']

Object.keys(object1).indexOf(key) === -1 ? 'the key is not there' : 'yep the key is exist';

You don't put a component in directives

You register it in @NgModule declarations:

@NgModule({
  imports: [ BrowserModule ],
  declarations: [ App , MyChildComponent ],
  bootstrap: [ App ]
})

and then You just put it in the Parent's Template HTML as : <my-child></my-child>

That's it.

UPDATE: Keep in mind, at the time the answer was initially written in 2010, the bellow function toFixed() worked slightly different. toFixed() seems to do some rounding now, but not in the strictly mathematical manner. So be careful with it. Do your tests... The method described bellow will do rounding well, as mathematician would expect.

• toFixed() - method converts a number into a string, keeping a specified number of decimals. It does not actually rounds up a number, it truncates the number.
• Math.round(n) - rounds a number to the nearest integer. Thus turning:

0.5 -> 1; 0.05 -> 0

so if you want to round, say number 0.55555, only to the second decimal place; you can do the following(this is step-by-step concept):

• 0.55555 * 100 = 55.555
• Math.Round(55.555) -> 56.000
• 56.000 / 100 = 0.56000
• (0.56000).toFixed(2) -> 0.56

and this is the code:

(Math.round(number * 100)/100).toFixed(2);

If you have error INSTALL_FAIL_DEXOPT, see in manifest android:targetSdkVersion. Set version < 21 sample:

android:targetSdkVersion="19"

This worked for me.

If you're on some Linux system, imagemagick is perfect. I.e

convert somefile.png somefile.svg

This works with heaps of different formats.

For other media such as videos and audio use (ffmpeg) I know you clearly stated png to svg, however; It's still media related.

ffmpeg -i somefile.mp3 somefile.ogg

Just a tip for if you wish to go through lots of files; a loop using basic shell tricks..

for f in *.jpg; do convert $f ${f%jpg}png; done

That removes the jpg and adds png which tells convert what you want.

This approach works well:

gci C:\Projects *.config -recurse | ForEach {
  (Get-Content $_ | ForEach {$_ -replace "old", "new"}) | Set-Content $_ 
}

• Change "old" and "new" to their corresponding values (or use variables).
• Don't forget the parenthesis -- without which you will receive an access error.

Angular Cli 8 support Node Js 10.9+. After update Node.js to 10.16 works fine.

1. Do a right click->properties on the file in Visual Studio.
2. Set the Copy to Output Directory to Copy always.

Then you will be able to reference your files by using a path such as @".\my_html.html"

Copy to Output Directory will put the file in the same folder as your binary dlls when the project is built. This works with any content file, even if its in a sub folder.

If you use a sub folder, that too will be copied in to the bin folder so your path would then be @".\my_subfolder\my_html.html"

In order to create a URI you can use locally (instead of served via the web), you'll need to use the file protocol, using the base directory of your binary - note: this will only work if you set the Copy to Ouptut Directory as above or the path will not be correct.

This is what you need:

string curDir = Directory.GetCurrentDirectory();
this.webBrowser1.Url = new Uri(String.Format("file:///{0}/my_html.html", curDir));

You'll have to change the variables and names of course.

Just an FYI, clearer, more readable syntax IMHO

"use strict";
String.prototype.pad = function( len, c, left ) {
    var s = '',
        c = ( c || ' ' ),
        len = Math.max( len, 0 ) - this.length,
        left = ( left || false );
    while( s.length < len ) { s += c };
    return ( left ? ( s + this ) : ( this + s ) );
}
Number.prototype.pad = function( len, c, left ) {
    return String( this ).pad( len, c, left );
}
Number.prototype.lZpad = function( len ) {
    return this.pad( len, '0', true );
}

This also results in less visual and readability glitches of the results than some of the other solutions, which enforce '0' as a character; answering my questions what do I do if I want to pad other characters, or on the other direction (right padding), whilst remaining easy to type, and clear to read. Pretty sure it's also the DRY'est example, with the least code for the actual leading-zero-padding function body (as the other dependent functions are largely irrelevant to the question).

The code is available for comment via gist from this github user (original source of the code) https://gist.github.com/Lewiscowles1986/86ed44f428a376eaa67f

A note on console & script testing, numeric literals seem to need parenthesis, or a variable in order to call methods, so 2.pad(...) will cause an error, whilst (2).pad(0,'#') will not. This is the same for all numbers it seems

How to delete a database in phpMyAdmin?

From the Operations tab of the database, look for (and click) the text Drop the database (DROP).

The simplest method (inline, assuming a and b are two given arrays):

byte[] c = (new String(a, cch) + new String(b, cch)).getBytes(cch);

This, of course, works with more than two summands and uses a concatenation charset, defined somewhere in your code:

static final java.nio.charset.Charset cch = java.nio.charset.StandardCharsets.ISO_8859_1;

Or, in more simple form, without this charset:

byte[] c = (new String(a, "l1") + new String(b, "l1")).getBytes("l1");

But you need to suppress UnsupportedEncodingException which is unlikely to be thrown.

The fastest method:

public static byte[] concat(byte[] a, byte[] b) {
    int lenA = a.length;
    int lenB = b.length;
    byte[] c = Arrays.copyOf(a, lenA + lenB);
    System.arraycopy(b, 0, c, lenA, lenB);
    return c;
}

If it helps, I was using centrifuge with my reactjs app, and, after checking some comments below, I looked at the centrifuge.js library file, which in my version, had the following code snippet:

if ('withCredentials' in xhr) {
 xhr.withCredentials = true;
}

After I removed these three lines, the app worked fine, as expected.

Hope it helps!

@Alistair pointed out in this answer that sometimes users will return to the browser after opening the app. A commenter to that answer indicated that the times values used had to be changed depending on iOS version. When our team had to deal with this, we found that the time values for the initial timeout and telling whether we had returned to the browser had to be tuned, and often didn't work for all users and devices.

Rather than using an arbitrary time difference threshold to determine whether we had returned to the browser, it made sense to detect the "pagehide" and "pageshow" events.

I developed the following web page to help diagnose what was going on. It adds HTML diagnostics as the events unfold, mainly because using techniques like console logging, alerts, or Web Inspector, jsfiddle.net etc all had their drawbacks in this work flow. Rather than using a time threshold, the Javascript counts the number of "pagehide" and "pageshow" events to see whether they have occurred. And I found that the most robust strategy was to use an initial timeout of 1000 (rather than the 25, 50, or 100 reported/suggested by others).

This can be served on a local server, e.g. python -m SimpleHTTPServer and viewed on iOS Safari.

To play with it, press either the "Open an installed app" or "App not installed" links. These links should cause respectively the Maps app or the App Store to open. You can then return to Safari to see the sequence and timing of the events.

(Note: this will work for Safari only. For other browsers (like Chrome) you'd have to install handlers for the pagehide/show-equivalent events).

Update: As @Mikko has pointed out in the comments, the pageshow/pagehide events we are using are apparently no longer supported in iOS8.

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

an edited version of what Alejandro García Iglesias put.

This allows you to pick a specific location of the string you want to get based on the number of times the result is found.

function get_string_between_pos($string, $start, $end, $pos){
    $cPos = 0;
    $ini = 0;
    $result = '';
    for($i = 0; $i < $pos; $i++){
      $ini = strpos($string, $start, $cPos);
      if ($ini == 0) return '';
      $ini += strlen($start);
      $len = strpos($string, $end, $ini) - $ini;
      $result = substr($string, $ini, $len);
      $cPos = $ini + $len;
    }
    return $result;
  }

usage:

$text = 'string has start test 1 end and start test 2 end and start test 3 end to print';

//get $result = "test 1"
$result = $this->get_string_between_pos($text, 'start', 'end', 1);

//get $result = "test 2"
$result = $this->get_string_between_pos($text, 'start', 'end', 2);

//get $result = "test 3"
$result = $this->get_string_between_pos($text, 'start', 'end', 3);

strpos has an additional optional input to start its search at a specific point. so I store the previous position in $cPos so when the for loop checks again, it starts at the end of where it left off.

Method 1:

txtNext.setOnClickListener {
        //Code statements
    }

Method 2:

class FirstActivity : AppCompatActivity(), View.OnClickListener {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_first)
    txtNext.setOnClickListener(this)
}

override fun onClick(v: View) {
    when (v.id) {
        R.id.txtNext -> {
            //Code statements
        }
        else -> {
            // else condition
        }
    }
  }
}

So with Angular 1.5.1 ( had existing app dependency on some other MEAN stack dependencies is why I'm not currently using 1.6.4 )

This works for me like the OP saying {{myVar === "two" ? "it's true" : "it's false"}}

For my Mac, extensions were here:

~/Library/Application Support/Google/Chrome/Default/Extensions/

if you go to chrome://extensions you'll find the "ID" of each extension. That is going to be a directory within Extensions directory. It is there you'll find all of the extension's files.

Using Carbon:

$dt = Carbon::now();
echo $dt->addYears(5); 

Splits an array in multiple arrays with a fixed maximum size.

public static <T extends Object> List<T[]> splitArray(T[] array, int max){

  int x = array.length / max;
  int r = (array.length % max); // remainder

  int lower = 0;
  int upper = 0;

  List<T[]> list = new ArrayList<T[]>();

  int i=0;

  for(i=0; i<x; i++){

    upper += max;

    list.add(Arrays.copyOfRange(array, lower, upper));

    lower = upper;
  }

  if(r > 0){

    list.add(Arrays.copyOfRange(array, lower, (lower + r)));

  }

  return list;
}

Example - an Array of 11 shall be splitted into multiple Arrays not exceeding a size of 5:

// create and populate an array
Integer[] arr = new Integer[11];

for(int i=0; i<arr.length; i++){
  arr[i] = i;
}

// split into pieces with a max. size of 5
List<Integer[]> list = ArrayUtil.splitArray(arr, 5);

// check
for(int i=0; i<list.size(); i++){

  System.out.println("Array " + i);

  for(int j=0; j<list.get(i).length; j++){
    System.out.println("  " + list.get(i)[j]);
  }
}

Output:

Array 0
  0
  1
  2
  3
  4
Array 1
  5
  6
  7
  8

Generally speaking, no. Views are primarily used for convenience and security, and won't (by themselves) produce any speed benefit.

That said, SQL Server 2000 and above do have a feature called Indexed Views that can greatly improve performance, with a few caveats:

1. Not every view can be made into an indexed view; they have to follow a specific set of guidelines, which (among other restrictions) means you can't include common query elements like COUNT, MIN, MAX, or TOP.
2. Indexed views use physical space in the database, just like indexes on a table.

This article describes additional benefits and limitations of indexed views:

You Can…

• The view definition can reference one or more tables in the same database.
• Once the unique clustered index is created, additional nonclustered indexes can be created against the view.
• You can update the data in the underlying tables – including inserts, updates, deletes, and even truncates.

You Can’t…

• The view definition can’t reference other views, or tables in other databases.
• It can’t contain COUNT, MIN, MAX, TOP, outer joins, or a few other keywords or elements.
• You can’t modify the underlying tables and columns. The view is created with the WITH SCHEMABINDING option.
• You can’t always predict what the query optimizer will do. If you’re using Enterprise Edition, it will automatically consider the unique clustered index as an option for a query – but if it finds a “better” index, that will be used. You could force the optimizer to use the index through the WITH NOEXPAND hint – but be cautious when using any hint.

I do it using the following :-

package main

import (
    "fmt"
    "strings"
)

func main (){
    concatenation:= strings.Join([]string{"a","b","c"},"") //where second parameter is a separator. 
    fmt.Println(concatenation) //abc
}

UPDATE or DELETE a record isn't allowed in Hive, but INSERT INTO is acceptable.
A snippet from Hadoop: The Definitive Guide(3rd edition):

Updates, transactions, and indexes are mainstays of traditional databases. Yet, until recently, these features have not been considered a part of Hive's feature set. This is because Hive was built to operate over HDFS data using MapReduce, where full-table scans are the norm and a table update is achieved by transforming the data into a new table. For a data warehousing application that runs over large portions of the dataset, this works well.

Hive doesn't support updates (or deletes), but it does support INSERT INTO, so it is possible to add new rows to an existing table.

In this case I would use a definition list as so:

<dl>
  <dt>Fruits I like:</dt>
  <dd>Apples</dd>
  <dd>Bananas</dd>
  <dd>Oranges</dd>
</dl>

del my_dict[key] is slightly faster than my_dict.pop(key) for removing a key from a dictionary when the key exists

>>> import timeit
>>> setup = "d = {i: i for i in range(100000)}"

>>> timeit.timeit("del d[3]", setup=setup, number=1)
1.79e-06
>>> timeit.timeit("d.pop(3)", setup=setup, number=1)
2.09e-06
>>> timeit.timeit("d2 = {key: val for key, val in d.items() if key != 3}", setup=setup, number=1)
0.00786

But when the key doesn't exist if key in my_dict: del my_dict[key] is slightly faster than my_dict.pop(key, None). Both are at least three times faster than del in a try/except statement:

>>> timeit.timeit("if 'missing key' in d: del d['missing key']", setup=setup)
0.0229
>>> timeit.timeit("d.pop('missing key', None)", setup=setup)
0.0426
>>> try_except = """
... try:
...     del d['missing key']
... except KeyError:
...     pass
... """
>>> timeit.timeit(try_except, setup=setup)
0.133

You can save some homemade factorial functions on a separate module, utils.py, and then import them and compare the performance with the predefinite one, in scipy, numpy and math using timeit. In this case I used as external method the last proposed by Stefan Gruenwald:

import numpy as np


def factorial(n):
    return reduce((lambda x,y: x*y),range(1,n+1))

Main code (I used a framework proposed by JoshAdel in another post, look for how-can-i-get-an-array-of-alternating-values-in-python):

from timeit import Timer
from utils import factorial
import scipy

    n = 100

    # test the time for the factorial function obtained in different ways:

    if __name__ == '__main__':

        setupstr="""
    import scipy, numpy, math
    from utils import factorial
    n = 100
    """

        method1="""
    factorial(n)
    """

        method2="""
    scipy.math.factorial(n)  # same algo as numpy.math.factorial, math.factorial
    """

        nl = 1000
        t1 = Timer(method1, setupstr).timeit(nl)
        t2 = Timer(method2, setupstr).timeit(nl)

        print 'method1', t1
        print 'method2', t2

        print factorial(n)
        print scipy.math.factorial(n)

Which provides:

method1 0.0195569992065
method2 0.00638914108276

If it's just for display purposes, you can render the text as upper or lower case in pure CSS, without any Javascript using the text-transform property:

.myclass {
    text-transform: lowercase;
}

See https://developer.mozilla.org/en/CSS/text-transform for more info.

However, note that this doesn't actually change the value to lower case; it just displays it that way. This means that if you examine the contents of the element (ie using Javascript), it will still be in its original format.

I think this is because you are using client software and not the server.

• mysql is client
• mysqld is the server

Try: sudo service mysqld start

To check that service is running use: ps -ef | grep mysql | grep -v grep.

Uninstalling:

sudo apt-get purge mysql-server
sudo apt-get autoremove
sudo apt-get autoclean

Re-Installing:

sudo apt-get update
sudo apt-get install mysql-server

Backup entire folder before doing this:

sudo rm /etc/apt/apt.conf.d/50unattended-upgrades*
sudo apt-get update
sudo apt-get upgrade

Functionality: A set of contracts which affect the compiler, assembly writers, the linker, and the operating system. The contracts specify how functions are laid out, where parameters are passed, how parameters are passed, how function returns work. These are generally specific to a (processor architecture, operating system) tuple.

Existing entities: parameter layout, function semantics, register allocation. For instance, the ARM architectures has numerous ABIs (APCS, EABI, GNU-EABI, never mind a bunch of historical cases) - using the a mixed ABI will result in your code simply not working when calling across boundaries.

Consumer: The compiler, assembly writers, operating system, CPU specific architecture.

Who needs these details? The compiler, assembly writers, linkers which do code generation (or alignment requirements), operating system (interrupt handling, syscall interface). If you did assembly programming, you were conforming to an ABI!

C++ name mangling is a special case - its a linker and dynamic linker centered issue - if name mangling is not standardized, then dynamic linking will not work. Henceforth, the C++ ABI is called just that, the C++ ABI. It is not a linker level issue, but instead a code generation issue. Once you have a C++ binary, it is not possible to make it compatible with another C++ ABI (name mangling, exception handling) without recompiling from source.

ELF is a file format for the use of a loader and dynamic linker. ELF is a container format for binary code and data, and as such specifies the ABI of a piece of code. I would not consider ELF to be an ABI in the strict sense, as PE executables are not an ABI.

All ABIs are instruction set specific. An ARM ABI will not make sense on an MSP430 or x86_64 processor.

Windows has several ABIs - for instance, fastcall and stdcall are two common use ABIs. The syscall ABI is different again.

When a module is loaded from a file in Python, __file__ is set to its path. You can then use that with other functions to find the directory that the file is located in.

Taking your examples one at a time:

A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.

B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.

C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.

You can see the various values returned from these here:

import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))

and make sure you run it from different locations (such as ./text.py, ~/python/text.py and so forth) to see what difference that makes.

I just want to address some confusion first. __file__ is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.

http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.

In this case __file__ is an attribute of a module (a module object). In Python a .py file is a module. So import amodule will have an attribute of __file__ which means different things under difference circumstances.

Taken from the docs:

__file__ is the pathname of the file from which the module was loaded, if it was loaded from a file. The __file__ attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.

In your case the module is accessing it's own __file__ attribute in the global namespace.

To see this in action try:

# file: test.py

print globals()
print __file__

And run:

python test.py

{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
 'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py

You can overwrite the classes in your own css using !important, e.g. if you want to get rid of the rounded corners.

.ui-corner-all
{
border-radius: 0px !important;
}

It is better to create new environment with new name ($newenv):conda create -n $newenv tensorflow

Then by using anaconda navigator under environment tab you can find newenv in the middle column.

By clicking on the play button open terminal and type: activate tensorflow

Then install tensorflow inside the newenv by typing: pip install tensorflow

Now you have tensorflow inside the new environment so then install jupyter by typing: pip install jupyter notebook

Then just simply type: jupyter notebook to run the jupyter notebook.

Inside of the jupyter notebook type: import tensorflow as tf

To test the the tf you can use THIS LINK

This has a more elegant explanation and more than one possible solutions. http://kasunh.wordpress.com/2011/10/11/preserving-remote-iphost-while-proxying/

The post describes how to use one popular and one lesser known Apache modules to preserve host/ip while in a setup involving proxying.

Use mod_rpaf module, install and enable it in the backend server and add following directives in the module’s configuration. RPAFenable On
RPAFsethostname On
RPAFproxy_ips 127.0.0.1

(2017 edit) Current location of mod_rpaf: https://github.com/gnif/mod_rpaf

#issubclass(child,parent)

class a:
    pass
class b(a):
    pass
class c(b):
    pass

print(issubclass(c,b))#it returns true

foreach (DataGridViewRow row in dgvWebData.Rows)
{
    if (Convert.ToString(row.Cells["IssuerName"].Value) != Convert.ToString(row.Cells["SearchTermUsed"].Value))
    {
        row.DefaultCellStyle.BackColor = Color.Yellow;
    }
    else
    {
        row.DefaultCellStyle.BackColor = Color.White;
    }
}

This Perfectly worked for me . even if a row is changed, same event takes care.

I'll assume you are not referring to literally the same objects

Object1 == Object2

You might be thinking about doing a memory comparison between the two

memcmp(Object1, Object2, sizeof(Object.GetType())

But that's not even real code in c# :). Because all of your data is probably created on the heap, the memory is not contiguous and you can't just compare the equality of two objects in an agnostic manner. You're going to have to compare each value, one at a time, in a custom way.

Consider adding the IEquatable<T> interface to your class, and define a custom Equals method for your type. Then, in that method, manual test each value. Add IEquatable<T> again on enclosed types if you can and repeat the process.

class Foo : IEquatable<Foo>
{
  public bool Equals(Foo other)
  {
    /* check all the values */
    return false;
  }
}

Here is another tidyverse approach using the modify_at() function from the purrr package.

library(purrr)

# Data frame with only integer columns
data <- data.frame(matrix(sample(1:40), 4, 10, dimnames = list(1:4, LETTERS[1:10])))

# Modify specified columns to a factor class
data_with_factors <- data %>%
    purrr::modify_at(c("A", "C", "E"), factor)


# Check the results:
str(data_with_factors)
# 'data.frame':   4 obs. of  10 variables:
#  $ A: Factor w/ 4 levels "8","12","33",..: 1 3 4 2
#  $ B: int  25 32 2 19
#  $ C: Factor w/ 4 levels "5","15","35",..: 1 3 4 2
#  $ D: int  11 7 27 6
#  $ E: Factor w/ 4 levels "1","4","16","20": 2 3 1 4
#  $ F: int  21 23 39 18
#  $ G: int  31 14 38 26
#  $ H: int  17 24 34 10
#  $ I: int  13 28 30 29
#  $ J: int  3 22 37 9

A really simple way is to:

git describe --always

You can look at the HEAD pointer (stored in .git/HEAD) to see the sha1 of the currently checked-out commit, or it will be of the format ref: refs/heads/foo for example if you have a local ref foo checked out.

EDIT: If you'd like to do this from a shell, git symbolic-ref HEAD will give you the same information.

Have you googled about it - insert update delete access vb.net, there are lots of reference about this.

Insert Update Delete Navigation & Searching In Access Database Using VB.NET

• Create Visual Basic 2010 Project: VB-Access
• Assume that, we have a database file named data.mdb
• Place the data.mdb file into ..\bin\Debug\ folder (Where the project executable file (.exe) is placed)

what could be the easier way to connect and manipulate the DB?
Use OleDBConnection class to make connection with DB

is it by using MS ACCESS 2003 or MS ACCESS 2007?
you can use any you want to use or your client will use on their machine.

it seems that you want to find some example of opereations fo the database. Here is an example of Access 2010 for your reference:

Example code snippet:

    # Dependencies
    import numpy as np
    import matplotlib.pyplot as plt

    #Set Axes
    # Set x axis to numerical value for month
    x_axis_data = np.arange(1,13,1)
    x_axis_data

    # Average weather temp
    points = [39, 42, 51, 62, 72, 82, 86, 84, 77, 65, 55, 44]

    # Plot the line
    plt.plot(x_axis_data, points)
    plt.show()

    # Convert to Celsius C = (F-32) * 0.56
    points_C = [round((x-32) * 0.56,2) for x in points]
    points_C

    # Plot using Celsius
    plt.plot(x_axis_data, points_C)
    plt.show()

    # Plot both on the same chart
    plt.plot(x_axis_data, points)
    plt.plot(x_axis_data, points_C)

    #Line colors
    plt.plot(x_axis_data, points, "-b", label="F")
    plt.plot(x_axis_data, points_C, "-r", label="C")

    #locate legend
    plt.legend(loc="upper left")
    plt.show()

let's say you want a pointer to point at the address 0x28ff4402, the usual way is

uint32_t *ptr;
ptr = (uint32_t*) 0x28ff4402 //type-casting the address value to uint32_t pointer
*ptr |= (1<<13) | (1<<10); //access the address how ever you want

So the short way is to use a MACRO,

#define ptr *(uint32_t *) (0x28ff4402)

For a single file, you could do:

svn export -r <REV> svn://host/path/to/file/on/repos file.ext

You could do svn revert <file> but that will only restore the last working copy.

You should try using quotes.

cmd /C "C:\Program Files (x86)\WinRar\Rar.exe" a "D:\Hello 2\File.rar" "D:\Hello 2\*.*"

Remember to install AccessDatabaseEngine on server for web application.

I felt like replying as well, explaining the same thing as the others a bit differently. I am sure you know most of this, but it might help someone else.

<a href="#" class="view">

The

href="#"

part is a commonly used way to make sure the link doesn't lead anywhere on it's own. the #-attribute is used to create a link to some other section in the same document. For example clicking a link of this kind:

<a href="#news">Go to news</a>

will take you to wherever you have the

<a name="news"></a>

code. So if you specify # without any name like in your case, the link leads nowhere.

The

class="view"

part gives it an identifier that CSS or javascript can use. Inside the CSS-files (if you have any) you will find specific styling procedures on all the elements tagged with the "view"-class.

To find out where the URL is specified I would look in the javascript code. It is either written directly in the same document or included from another file.

Search your source code for something like:

<script type="text/javascript"> bla bla bla </script>

or

<script> bla bla bla </script>

and then search for any reference to your "view"-class. An included javascript file can look something like this:

<script type="text/javascript" src="include/javascript.js"></script>

In that case, open javascript.js under the "include" folder and search in that file. Most commonly the includes are placed between <head> and </head> or close to the </body>-tag.

A faster way to find the link is to search for the actual link it goes to. For example, if you are directed to http://www.google.com/search?q=html when you click it, search for "google.com" or something in all the files you have in your web project, just remember the included files.

In many text editors you can open all the files at once, and then search in them all for something.

$ find proj

proj
proj/src
proj/src/index.js

$ cat proj/src/index.js

console.log("process.cwd() = " + process.cwd());
console.log("__dirname = " + __dirname);

$ cd proj; node src/index.js

process.cwd() = /tmp/proj
__dirname = /tmp/proj/src

Some may want to simply suppress the warning:

class SupressSettingWithCopyWarning:
    def __enter__(self):
        pd.options.mode.chained_assignment = None

    def __exit__(self, *args):
        pd.options.mode.chained_assignment = 'warn'

with SupressSettingWithCopyWarning():
    #code that produces warning

You can also use EXIT_SUCCESS instead of return 0;. The macro EXIT_SUCCESS is actually defined as zero, but makes your program more readable.

The Node.js package is available in the LTS release and the current release. It’s your choice to select which version you want to install on the system as per your requirements.

Use Current Release: At the last update of this tutorial, Node.js 13 is the current Node.js release available.

sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_13.x | sudo -E bash -

Use LTS Release: At the last update of this tutorial, Node.js 12.x is the LTS release available.

sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -

You can successfully add Node.js PPA to the Ubuntu system. Now execute the below command to install Node.js on and Ubuntu using apt-get. This will also install NPM with Node.js. This command also installs many other dependent packages on your system.

sudo apt-get install nodejs

After installing Node.js, verify and check the installed version. You can find more details about the current version on the Node.js official website.

node -v

v13.0.1

Also, check the npm version:

npm -v

6.12.0

I don't know why but for me the solution proposed by Marius Stanescu is breaking the specificity of col (a col-md-3 followed by a col-md-4 will take all of the twelve row)

I found another working solution :

.bottom-column 
{
   display: inline-block;
   vertical-align: middle;
   float: none;
}

If you used...

$(function(){
    function myFunc() {
        // ... do something ...
    };
    $('#saveBtn').click(myFunc);
});

... then it will be easier to unbind later.

In ionic 4.6 I use the following technique and it works. I am adding this answer so that if anybody is facing similar issues in newer ionic version app, it may help them.

i) Open app.module.ts and add the following code block to import HttpModule and HttpClientModule

import { HttpModule } from '@angular/http';
import {   HttpClientModule } from '@angular/common/http';

ii) In @NgModule import sections add below lines:

HttpModule,
HttpClientModule,

So, in my case @NgModule, looks like this:

@NgModule({
  declarations: [AppComponent ],
  entryComponents: [ ],
  imports: [
    BrowserModule,
    HttpModule,
    HttpClientModule,
    IonicModule.forRoot(),
    AppRoutingModule, 
  ],
  providers: [
    StatusBar,
    SplashScreen,
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
  ],
  bootstrap: [AppComponent]
})

That's it!
