You need to set useaccessibleheader attribute of the gridview to true and also then also specify a TableSection to be a header after calling the DataBind() method on you GridView object. So if your grid view is mygv

mygv.UseAccessibleHeader = True
mygv.HeaderRow.TableSection = TableRowSection.TableHeader

This should result in a proper formatted grid with thead and tbody tags

Here is another simple answer

gsub("^.*:","", string)

DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);

assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.

The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.

As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.

If you need to parse other formats, you can check out the Standard DateTime Format Strings.

I think pi has ssh server enabled by default. Mine have always worked out of the box. Depends which operating system version maybe.

Most of the time when it fails for me it is because the ip address has been changed. Perhaps you are pinging something else now? Also sometimes they just refuse to connect and need a restart.

If you go to the Flat file connection manager under Advanced and Look at the "OutputColumnWidth" description's ToolTip It will tell you that Composit characters may use more spaces. So the "é" in "Société" most likely occupies more than one character.

EDIT: Here's something about it: http://en.wikipedia.org/wiki/Precomposed_character

To match either / or end of content, use (/|\z)

This only applies if you are not using multi-line matching (i.e. you're matching a single URL, not a newline-delimited list of URLs).

To put that with an updated version of what you had:

/(\S+?)/(\d{4}-\d{2}-\d{2})-(\d+)(/|\z)

Note that I've changed the start to be a non-greedy match for non-whitespace ( \S+? ) rather than matching anything and everything ( .* )

If you really need to use sys.path.insert, consider leaving sys.path[0] as it is:

sys.path.insert(1, path_to_dev_pyworkbooks)

This could be important since 3rd party code may rely on sys.path documentation conformance:

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter.

Database Input - How to prevent SQL Injection

1. Check to make sure data of type integer, for example, is valid by ensuring it actually is an integer
   • In the case of non-strings you need to ensure that the data actually is the correct type
   • In the case of strings you need to make sure the string is surrounded by quotes in the query (obviously, otherwise it wouldn't even work)
2. Enter the value into the database while avoiding SQL injection (mysql_real_escape_string or parameterized queries)
3. When Retrieving the value from the database be sure to avoid Cross Site Scripting attacks by making sure HTML can't be injected into the page (htmlspecialchars)

You need to escape user input before inserting or updating it into the database. Here is an older way to do it. You would want to use parameterized queries now (probably from the PDO class).

$mysql['username'] = mysql_real_escape_string($clean['username']);
$sql = "SELECT * FROM userlist WHERE username = '{$mysql['username']}'";
$result = mysql_query($sql);

Output from database - How to prevent XSS (Cross Site Scripting)

Use htmlspecialchars() only when outputting data from the database. The same applies for HTML Purifier. Example:

$html['username'] = htmlspecialchars($clean['username'])

• Buy this book if you can: Essential PHP Security
• Also read this article: Why mysql_real_escape_string is important and some gotchas

And Finally... what you requested

I must point out that if you use PDO objects with parameterized queries (the proper way to do it) then there really is no easy way to achieve this easily. But if you use the old 'mysql' way then this is what you would need.

function filterThis($string) {
    return mysql_real_escape_string($string);
}

var temp="/yourapp/";
$(location).attr('href','http://abcd.com'+temp);

Try this... used as an alternative

I had the same problem, but it's solved now. Finally, Putty does work with Cigwin-X, and Xming is not an obligatory app for MS-Windows X-server.

Nowadays it's xlaunch, who controls the run of X-window. Certainly, xlaunch.exe must be installed in Cigwin. When run in interactive mode it asks for "extra settings". You should add "-listen tcp" to additional param field, since Cigwin-X does not listen TCP by default.

In order to not repeat these steps, you may save settings to the file. And run xlaunch.exe via its shortcut with modified CLI inside. Something like

C:\cygwin64\bin\xlaunch.exe -run C:\cygwin64\config.xlaunch

I do get the same information while debugging. Though not while I am checking the stacktrace. Most probably you would have used the optimization flag I think. Check this link - something related.

Try compiling with -g3 remove any optimization flag. Then it might work. HTH!

When using merged columns, I got it centered by using PHPExcel_Style_Alignment::HORIZONTAL_CENTER_CONTINUOUS instead of PHPExcel_Style_Alignment::HORIZONTAL_CENTER

The return value def __unicode __ should be similar to the return value of the related models (tables) for correct viewing of "some_field" in django admin panel. You can also use:

def __str__(self):
    return self.some_field

Here's why I like the 80-character with: at work I use Vim and work on two files at a time on a monitor running at, I think, 1680x1040 (I can never remember). If the lines are any longer, I have trouble reading the files, even when using word wrap. Needless to say, I hate dealing with other people's code as they love long lines.

Cloning a specific tag, might return 'detached HEAD' state.

As a workaround, try to clone the repo first, and then checkout a specific tag. For example:

repo_url=https://github.com/owner/project.git
repo_dir=$(basename $repo_url .git)
repo_tag=0.5

git clone --single-branch $repo_url # using --depth 1 can show no tags
git --work-tree=$repo_dir --git-dir=$repo_dir/.git checkout tags/$repo_tag

Note: Since Git 1.8.5, you can use -C <path>, instead of --work-tree and --git-dir.

Just ignore parameter passing as a false in java script functions

Ex:

function getCities(stateId,locationId=false){    

    // Avoid writting locationId= false kind of statements
   /*your code comes here*/

 }

Avoid writting locationId= false kind of statements, As this will give the error in chrome and IE

You do not include a <scope> tag in your dependency. If you add it, your dependency becomes something like:

<dependency>
     <groupId>org.openrdf.sesame</groupId>
     <artifactId>sesame-runtime</artifactId>
     <version>2.7.2</version>
     <scope> ... </scope>
</dependency>

The "scope" tag tells maven at which stage of the build your dependency is needed. Examples for the values to put inside are "test", "provided" or "runtime" (omit the quotes in your pom). I do not know your dependency so I cannot tell you what value to choose. Please consult the Maven documentation and the documentation of your dependency.

Assuming a is a string. The Slice notation in python has the syntax -

list[<start>:<stop>:<step>]

So, when you do a[::-1], it starts from the end towards the first taking each element. So it reverses a. This is applicable for lists/tuples as well.

Example -

>>> a = '1234'
>>> a[::-1]
'4321'

Then you convert it to int and then back to string (Though not sure why you do that) , that just gives you back the string.

Looking at posted answers I think this code would be also an alternative for someone. Nobody above used .Shapes.AddPicture in their code, only .Pictures.Insert()

Dim myPic As Object
Dim picpath As String

picpath = "C:\Users\photo.jpg" 'example photo path

Set myPic = ws.Shapes.AddPicture(picpath, False, True, 20, 20, -1, -1)

With myPic
    .Width = 25
    .Height = 25
    .Top = xlApp.Cells(i, 20).Top 'according to variables from correct answer
    .Left = xlApp.Cells(i, 20).Left
    .LockAspectRatio = msoFalse
End With

I'm working in Excel 2013. Also realized that You need to fill all the parameters in .AddPicture, because of error "Argument not optional". Looking at this You may ask why I set Height and Width as -1, but that doesn't matter cause of those parameters are set underneath between With brackets.

Hope it may be also useful for someone :)

Use the Format function.

Format(Date, "yyyy-mm-dd hh:MM:ss")

Yes by using spring-boot with hibernate configuration files we can persist the data to the database. keep hibernating .cfg.xml in your src/main/resources folder for reading the configurations related to database.

I found the ioctl solution problematic on os x (which is POSIX compliant so should be similiar to linux). However getifaddress() will let you do the same thing easily, it works fine for me on os x 10.5 and should be the same below.

I've done a quick example below which will print all of the machine's IPv4 address, (you should also check the getifaddrs was successful ie returns 0).

I've updated it show IPv6 addresses too.

#include <stdio.h>      
#include <sys/types.h>
#include <ifaddrs.h>
#include <netinet/in.h> 
#include <string.h> 
#include <arpa/inet.h>

int main (int argc, const char * argv[]) {
    struct ifaddrs * ifAddrStruct=NULL;
    struct ifaddrs * ifa=NULL;
    void * tmpAddrPtr=NULL;

    getifaddrs(&ifAddrStruct);

    for (ifa = ifAddrStruct; ifa != NULL; ifa = ifa->ifa_next) {
        if (!ifa->ifa_addr) {
            continue;
        }
        if (ifa->ifa_addr->sa_family == AF_INET) { // check it is IP4
            // is a valid IP4 Address
            tmpAddrPtr=&((struct sockaddr_in *)ifa->ifa_addr)->sin_addr;
            char addressBuffer[INET_ADDRSTRLEN];
            inet_ntop(AF_INET, tmpAddrPtr, addressBuffer, INET_ADDRSTRLEN);
            printf("%s IP Address %s\n", ifa->ifa_name, addressBuffer); 
        } else if (ifa->ifa_addr->sa_family == AF_INET6) { // check it is IP6
            // is a valid IP6 Address
            tmpAddrPtr=&((struct sockaddr_in6 *)ifa->ifa_addr)->sin6_addr;
            char addressBuffer[INET6_ADDRSTRLEN];
            inet_ntop(AF_INET6, tmpAddrPtr, addressBuffer, INET6_ADDRSTRLEN);
            printf("%s IP Address %s\n", ifa->ifa_name, addressBuffer); 
        } 
    }
    if (ifAddrStruct!=NULL) freeifaddrs(ifAddrStruct);
    return 0;
}

Get-Content -Encoding UTF8 FILE-UTF8.TXT | Out-File -Encoding UTF7 FILE-UTF7.TXT

The shortest version, if you can assume that the input BOM is correct:

gc FILE.TXT | Out-File -en utf7 file-utf7.txt

Math.Floor(123456.646 * 100) / 100 Would return 123456.64

From react docs Passing arguments to event handlers

<button onClick={(e) => this.deleteRow(id, e)}>Delete Row</button>
<button onClick={this.deleteRow.bind(this, id)}>Delete Row</button>

Syntax is Shown below:

"your condition"? "step if true":"step if condition fails"

The default is the first one in the definition. For example:

public enum MyEnum{His,Hers,Mine,Theirs}

Enum.GetValues(typeOf(MyEnum)).GetValue(0);

This will return His

you can try this, I would do it with CSS, but i think you want it with tables without CSS.

Here is another simple way.

var es, log, logFile;

es = require('event-stream');

log = require('gulp-util').log;

logFile = function(es) {
  return es.map(function(file, cb) {
    log(file.path);

In an SQL query, if the inner query executes for every row of the outer query. If the inner query is executed for once and the result is consumed by the outer query, then it is called as non co-related query.

Correlated sub-queries usually correspond to normal join queries, i.e. join queries that have no sub-queries, and can usually be expressed as such. It is sometimes recommended that they are translated into such join queries, because most SQL DBMSs will execute them .....

MSSQL requires that variables within procedures be DECLAREd and folks use the @Variable syntax (DECLARE @TEXT VARCHAR(25) = 'text'). Also, MS allows for declares within any block in the procedure, unlike mySQL which requires all the DECLAREs at the top.

While good on the command line, I feel using the "set = @variable" within stored procedures in mySQL is risky. There is no scope and variables live across scope boundaries. This is similar to variables in JavaScript being declared without the "var" prefix, which are then the global namespace and create unexpected collisions and overwrites.

I am hoping that the good folks at mySQL will allow DECLARE @Variable at various block levels within a stored procedure. Notice the @ (at sign). The @ sign prefix helps to separate variable names from table column names - as they are often the same. Of course, one can always add an "v" or "l_" prefix, but the @ sign is a handy and succinct way to have the variable name match the column you might be extracting the data from without clobbering it.

MySQL is new to stored procedures and they have done a good job for their first version. It will be a pleaure to see where they take it form here and to watch the server side aspects of the language mature.

Your array.xml is not right. change it to like this

Here is array.xml file

<?xml version="1.0" encoding="utf-8"?>  
<resources>  
    <string-array name="testArray">  
        <item>first</item>  
        <item>second</item>  
        <item>third</item>  
        <item>fourth</item>  
        <item>fifth</item>  
   </string-array>
</resources>

You can get the maximum like this:

>>> import pandas as pd
>>> df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
>>> df
   A  B
0  1 -2
1  2  8
2  3  1
>>> df[["A", "B"]]
   A  B
0  1 -2
1  2  8
2  3  1
>>> df[["A", "B"]].max(axis=1)
0    1
1    8
2    3

and so:

>>> df["C"] = df[["A", "B"]].max(axis=1)
>>> df
   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3

If you know that "A" and "B" are the only columns, you could even get away with

>>> df["C"] = df.max(axis=1)

And you could use .apply(max, axis=1) too, I guess.

Agree with 2nd most vote answer that it will make big difference when using LEFT JOIN or RIGHT JOIN. Actually, the two statements below are equivalent. So you can see that AND clause is doing a filter before JOIN while the WHERE clause is doing a filter after JOIN.

SELECT *
FROM dbo.Customers AS CUS 
LEFT JOIN dbo.Orders AS ORD 
ON CUS.CustomerID = ORD.CustomerID
AND ORD.OrderDate >'20090515'

SELECT *
FROM dbo.Customers AS CUS 
LEFT JOIN (SELECT * FROM dbo.Orders WHERE OrderDate >'20090515') AS ORD 
ON CUS.CustomerID = ORD.CustomerID

#pragma pack instructs the compiler to pack structure members with particular alignment. Most compilers, when you declare a struct, will insert padding between members to ensure that they are aligned to appropriate addresses in memory (usually a multiple of the type's size). This avoids the performance penalty (or outright error) on some architectures associated with accessing variables that are not aligned properly. For example, given 4-byte integers and the following struct:

struct Test
{
   char AA;
   int BB;
   char CC;
};

The compiler could choose to lay the struct out in memory like this:

|   1   |   2   |   3   |   4   |  

| AA(1) | pad.................. |
| BB(1) | BB(2) | BB(3) | BB(4) | 
| CC(1) | pad.................. |

and sizeof(Test) would be 4 × 3 = 12, even though it only contains 6 bytes of data. The most common use case for the #pragma (to my knowledge) is when working with hardware devices where you need to ensure that the compiler does not insert padding into the data and each member follows the previous one. With #pragma pack(1), the struct above would be laid out like this:

|   1   |

| AA(1) |
| BB(1) |
| BB(2) |
| BB(3) |
| BB(4) |
| CC(1) |

And sizeof(Test) would be 1 × 6 = 6.

With #pragma pack(2), the struct above would be laid out like this:

|   1   |   2   | 

| AA(1) | pad.. |
| BB(1) | BB(2) |
| BB(3) | BB(4) |
| CC(1) | pad.. |

And sizeof(Test) would be 2 × 4 = 8.

Order of variables in struct is also important. With variables ordered like following:

struct Test
{
   char AA;
   char CC;
   int BB;
};

and with #pragma pack(2), the struct would be laid out like this:

|   1   |   2   | 

| AA(1) | CC(1) |
| BB(1) | BB(2) |
| BB(3) | BB(4) |

and sizeOf(Test) would be 3 × 2 = 6.

The simplest answer to the meaning of deprecated when used to describe software APIs is:

• Stop using APIs marked as deprecated!
• They will go away in a future release!!
• Start using the new versions ASAP!!!

You can put an <a> element inside the <div> and set it to display: block and height: 100%.

DataRow's are nice in the way that they have their underlying table linked to them. With the underlying table you can verify that a specific row has a specific column in it.

DELIMITER ;

and call by, mysql_connection specification and

$loginCheck="call sp_user_login('".$username."','".$password."');";

it will return the result from the procedure.

For Windows user, please note to use " instead of ' Also added -f to force the command if another backup is already there.

its worked for me new Random().nextInt(100); // MAX = number

it will give 0 to 99 random number

Eample::

If Node install script doesn't work for you (it didn't for me), here's the solution to update Node Js in Debian Jessie, taken from the reply from Thomas Ward at askubuntu.com (Thanks, buddy!).

1.- Create a new file: /etc/apt/sources.list.d/nodesource.list

You'll need to create this file with sudo, but when you create the file, put this inside it:

deb https://deb.nodesource.com/node_9.x jessie main
deb-src https://deb.nodesource.com/node_9.x jessie main

Then, save the file. (replace node_9.x with the desired version)

2.- Download the GPG Signing Key from Nodesource for the repository. Otherwise, you may get NO_PUBKEY errors with apt-get update:

curl -s https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -

3.- Manually run sudo apt-get update.

This refreshes the data from the nodesource repo so apt knows a newer version exists.

If you get a NO_PUBKEY GPG error, then go back to Step 2

4.- Check apt-cache policy nodejs output.

This is not done by the script, but you want to make sure you see an entry that says something like this in the output:

Version table:
 *** 9.2.0-1nodesource1 0
        500 https://deb.nodesource.com/node_9.x/ jessie/main amd64 Packages
        100 /var/lib/dpkg/status
     0.10.29~dfsg-2 0
        500 http://ftp.debian.org/debian/ jessie/main amd64 Packages

If you do not see entries like this, and only see 0.10.29, start over. Otherwise, proceed.

5.- Install the nodejs binary. Now that you have confirmed 9.x is available on your system, you can install it: sudo apt-get install nodejs

nodejs -v should now show v9.2 or similar on output (as long as it starts with v9. you're on version 9 then).

Yep, Oracle has temporary tables. Here is a link to an AskTom article describing them and here is the official oracle CREATE TABLE documentation.

However, in Oracle, only the data in a temporary table is temporary. The table is a regular object visible to other sessions. It is a bad practice to frequently create and drop temporary tables in Oracle.

CREATE GLOBAL TEMPORARY TABLE today_sales(order_id NUMBER)
ON COMMIT PRESERVE ROWS;

Oracle 18c added private temporary tables, which are single-session in-memory objects. See the documentation for more details. Private temporary tables can be dynamically created and dropped.

CREATE PRIVATE TEMPORARY TABLE ora$ptt_today_sales AS
SELECT * FROM orders WHERE order_date = SYSDATE;

Temporary tables can be useful but they are commonly abused in Oracle. They can often be avoided by combining multiple steps into a single SQL statement using inline views.

$("#list li").click(function() {
        var selected = $(this).html();
        alert(selected);
});

Try dtIngest, it's developed on top of Apache Apex platform. This tool copies data from different sources like HDFS, shared drive, NFS, FTP, Kafka to different destinations. Copying data from remote HDFS cluster to local HDFS cluster is supported by dtIngest. dtIngest runs yarn jobs to copy data in parallel fashion, so it's very fast. It takes care of failure handling, recovery etc. and supports polling directories periodically to do continious copy.

Usage: dtingest [OPTION]... SOURCEURL... DESTINATIONURL example: dtingest hdfs://nn1:8020/source hdfs://nn2:8020/dest

If you are using SQL Server 2005 or above use this:

SELECT *
  FROM (
                SELECT  ID, 
                        Email, 
                        ProductName, 
                        ProductModel,
                        ROW_NUMBER() OVER(PARTITION BY Email ORDER BY ID DESC) rn
                    FROM Products
              ) a
WHERE rn = 1

EDIT: Example using a where clause:

SELECT *
  FROM (
                SELECT  ID, 
                        Email, 
                        ProductName, 
                        ProductModel,
                        ROW_NUMBER() OVER(PARTITION BY Email ORDER BY ID DESC) rn
                    FROM Products
                   WHERE ProductModel = 2
                     AND ProductName LIKE 'CYBER%'

              ) a
WHERE rn = 1

TLDR: You can first filter your array and then perform your map but this would require two passes on the array (filter returns an array to map). Since this array is small, it is a very small performance cost. You can also do a simple reduce. However if you want to re-imagine how this can be done with a single pass over the array (or any datatype), you can use an idea called "transducers" made popular by Rich Hickey.

Answer:

We should not require increasing dot chaining and operating on the array [].map(fn1).filter(f2)... since this approach creates intermediate arrays in memory on every reducing function.

The best approach operates on the actual reducing function so there is only one pass of data and no extra arrays.

The reducing function is the function passed into reduce and takes an accumulator and input from the source and returns something that looks like the accumulator

// 1. create a concat reducing function that can be passed into `reduce`
const concat = (acc, input) => acc.concat([input])

// note that [1,2,3].reduce(concat, []) would return [1,2,3]

// transforming your reducing function by mapping
// 2. create a generic mapping function that can take a reducing function and return another reducing function
const mapping = (changeInput) => (reducing) => (acc, input) => reducing(acc, changeInput(input))

// 3. create your map function that operates on an input
const getSrc = (x) => x.src
const mappingSrc = mapping(getSrc)

// 4. now we can use our `mapSrc` function to transform our original function `concat` to get another reducing function
const inputSources = [{src:'one.html'}, {src:'two.txt'}, {src:'three.json'}]
inputSources.reduce(mappingSrc(concat), [])
// -> ['one.html', 'two.txt', 'three.json']

// remember this is really essentially just
// inputSources.reduce((acc, x) => acc.concat([x.src]), [])


// transforming your reducing function by filtering
// 5. create a generic filtering function that can take a reducing function and return another reducing function
const filtering = (predicate) => (reducing) => (acc, input) => (predicate(input) ? reducing(acc, input): acc)

// 6. create your filter function that operate on an input
const filterJsonAndLoad = (img) => {
  console.log(img)
  if(img.src.split('.').pop() === 'json') {
    // game.loadSprite(...);
    return false;
  } else {
    return true;
  }
}
const filteringJson = filtering(filterJsonAndLoad)

// 7. notice the type of input and output of these functions
// concat is a reducing function,
// mapSrc transforms and returns a reducing function
// filterJsonAndLoad transforms and returns a reducing function
// these functions that transform reducing functions are "transducers", termed by Rich Hickey
// source: http://clojure.com/blog/2012/05/15/anatomy-of-reducer.html
// we can pass this all into reduce! and without any intermediate arrays

const sources = inputSources.reduce(filteringJson(mappingSrc(concat)), []);
// [ 'one.html', 'two.txt' ]

// ==================================
// 8. BONUS: compose all the functions
// You can decide to create a composing function which takes an infinite number of transducers to
// operate on your reducing function to compose a computed accumulator without ever creating that
// intermediate array
const composeAll = (...args) => (x) => {
  const fns = args
  var i = fns.length
  while (i--) {
    x = fns[i].call(this, x);
  }
  return x
}

const doABunchOfStuff = composeAll(
    filtering((x) => x.src.split('.').pop() !== 'json'),
    mapping((x) => x.src),
    mapping((x) => x.toUpperCase()),
    mapping((x) => x + '!!!')
)

const sources2 = inputSources.reduce(doABunchOfStuff(concat), [])
// ['ONE.HTML!!!', 'TWO.TXT!!!']

Since none of you mentioned nothing about the const keyword...

The const keyword modifies the type of a type declaration or the type of a function parameter, preventing the value from varying. (Source: MS)

In other words: passing a parameter by reference exposes it to modification by the callee. Using the const keyword prevents the modification.

I got same error in my application.I am loading many controls in single page.In button click event i am clearing the controls.clearing the controls doesnot release the controls from memory.So dispose the controls from memory. I just commented controls.clear() method and include few lines of code to dispose the controls. Something like this

Try character 10. It won't work in Firefox though. :(

The text is displayed (if at all) in a browser dependent manner. Small tooltips work on most browsers. Long tooltips and line breaking work in IE and Safari (use 
 or 
 for a new newline). Firefox and Opera do not support newlines. Firefox does not support long tooltips.

http://modp.com/wiki/htmltitletooltips

Update:

As of January 2015 Firefox does support using 
 to insert a line break in an HTML title attribute. See the snippet example below.

<a href="#" title="Line 1&#13;Line 2&#13;Line 3">Hover for multi-line title</a>

final indicates that the value of the variable won't change - in other words, a constant whose value can't be modified after it is declared.

Use public final static String when you want to create a String that:

1. belongs to the class (static: no instance necessary to use it), and that
2. won't change (final), for instance when you want to define a String constant that will be available to all instances of the class, and to other objects using the class.

Example:

public final static String MY_CONSTANT = "SomeValue";

// ... in some other code, possibly in another object, use the constant:
if (input.equals(MyClass.MY_CONSTANT)

Similarly:

public static final int ERROR_CODE = 127;

It isn't required to use final, but it keeps a constant from being changed inadvertently during program execution, and serves as an indicator that the variable is a constant.

Even if the constant will only be used - read - in the current class and/or in only one place, it's good practice to declare all constants as final: it's clearer, and during the lifetime of the code the constant may end up being used in more than one place.

Furthermore using final may allow the implementation to perform some optimization, e.g. by inlining an actual value where the constant is used.

This is an servlet code which contain a string variable a. the value for a is getting from an html page with form. then set the variable into the request object. then pass it to jsp using forward and requestdispatcher methods.

String a=req.getParameter("username");
req.setAttribute("name", a);
RequestDispatcher rd=req.getRequestDispatcher("/login.jsp");
rd.forward(req, resp);

in jsp follow these steps shown below in the program

<%String name=(String)request.getAttribute("name");
out.print("your name"+name);%>

InnoDB works slightly different that MyISAM and they both are viable options. You should use what you think it fits the project.

Some keypoints will be:

1. InnoDB does ACID-compliant transaction. http://en.wikipedia.org/wiki/ACID
2. InnoDB does Referential Integrity (foreign key relations) http://www.w3resource.com/sql/joins/joining-tables-through-referential-integrity.php
3. MyIsam does full text search, InnoDB doesn't
4. I have been told InnoDB is faster on executing writes but slower than MyISAM doing reads (I cannot back this up and could not find any article that analyses this, I do however have the guy that told me this in high regard), feel free to ignore this point or do your own research.
5. Default configuration does not work very well for InnoDB needs to be tweaked accordingly, run a tool like http://mysqltuner.pl/mysqltuner.pl to help you.

Notes:

• In my opinion the second point is probably the one were InnoDB has a huge advantage over MyISAM.
• Full text search not working with InnoDB is a bit of a pain, You can mix different storage engines but be careful when doing so.

Notes2: - I am reading this book "High performance MySQL", the author says "InnoDB loads data and creates indexes slower than MyISAM", this could also be a very important factor when deciding what to use.

Without more details as to what the question is exactly asking, I am going to answer the title of the question,

Create an Array:

String[] myArray = new String[2];
int[] intArray = new int[2];

// or can be declared as follows
String[] myArray = {"this", "is", "my", "array"};
int[] intArray = {1,2,3,4};

Create an ArrayList:

ArrayList<String> myList = new ArrayList<String>();
myList.add("Hello");
myList.add("World");

ArrayList<Integer> myNum = new ArrayList<Integer>();
myNum.add(1);
myNum.add(2);

This means, create an ArrayList of String and Integer objects. You cannot use int because thats a primitive data types, see the link for a list of primitive data types.

Create a Stack:

Stack myStack = new Stack();
// add any type of elements (String, int, etc..)
myStack.push("Hello");
myStack.push(1);

Create an Queue: (using LinkedList)

Queue<String> myQueue = new LinkedList<String>();
Queue<Integer> myNumbers = new LinkedList<Integer>();
myQueue.add("Hello");
myQueue.add("World");
myNumbers.add(1);
myNumbers.add(2);

Same thing as an ArrayList, this declaration means create an Queue of String and Integer objects.

Update:

In response to your comment from the other given answer,

i am pretty confused now, why are using string. and what does <String> means

We are using String only as a pure example, but you can add any other object, but the main point is that you use an object not a primitive type. Each primitive data type has their own primitive wrapper class, see link for list of primitive data type's wrapper class.

I have posted some links to explain the difference between the two, but here are a list of primitive types

• byte
• short
• char
• int
• long
• boolean
• double
• float

Which means, you are not allowed to make an ArrayList of integer's like so:

ArrayList<int> numbers = new ArrayList<int>(); 
           ^ should be an object, int is not an object, but Integer is!
ArrayList<Integer> numbers = new ArrayList<Integer>();
            ^ perfectly valid

Also, you can use your own objects, here is my Monster object I created,

public class Monster {
   String name = null;
   String location = null;
   int age = 0;

public Monster(String name, String loc, int age) { 
   this.name = name;
   this.loc = location;
   this.age = age;
 }

public void printDetails() {
   System.out.println(name + " is from " + location +
                                     " and is " + age + " old.");
 }
} 

Here we have a Monster object, but now in our Main.java class we want to keep a record of all our Monster's that we create, so let's add them to an ArrayList

public class Main {
    ArrayList<Monster> myMonsters = new ArrayList<Monster>();

public Main() {
    Monster yetti = new Monster("Yetti", "The Mountains", 77);
    Monster lochness = new Monster("Lochness Monster", "Scotland", 20);

    myMonsters.add(yetti); // <-- added Yetti to our list
    myMonsters.add(lochness); // <--added Lochness to our list
  
    for (Monster m : myMonsters) {
        m.printDetails();
     }
   }

public static void main(String[] args) {
    new Main();
 }
}

(I helped my girlfriend's brother with a Java game, and he had to do something along those lines as well, but I hope the example was well demonstrated)

For both hardware device back button and soft home (back) button e.g. " <- " this is what works for me. (*Note I have an app bar / toolbar in the activity)

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            //finish();
            onBackPressed();
            break;
    }
    return true;
}



@Override
public void onBackPressed() {
   //Execute your code here
   finish();

}

Cheers!

Expanding on @JetLaggy:

After trying again and again to modify .bash_profile with the MAMP directory, I changed the file permissions for the MAMP php directory and was able to get 'which php' to show the proper directory. Trouble was that other functions didn't work, such as 'php -v'.

So I updated MAMP. http://documentation.mamp.info/en/mamp/installation/updating-mamp

This did the trick for my particular setup. I had to adjust my PATH to reflect the updated version of PHP, but once I did, everything worked!

There are a number of ways to go about this. One way would be to enter the date 8/1/2013 manually in the first cell (say A1 for example's sake) and then in B1 type the following formula (and then drag it across):

=DATE(YEAR(A1),MONTH(A1)+1,1)

Since you only want to see month and year, you can format accordingly using the different custom date formats available.

The format you're looking for is YY-Mmm.

It happens when $ret hasn't been defined. The solution is simple. Right above $tags = get_tags();, add the following line:

$ret = array();

Using the Schwartzian transform from Perl,

py = [{'name':'Homer', 'age':39}, {'name':'Bart', 'age':10}]

do

sort_on = "name"
decorated = [(dict_[sort_on], dict_) for dict_ in py]
decorated.sort()
result = [dict_ for (key, dict_) in decorated]

gives

>>> result
[{'age': 10, 'name': 'Bart'}, {'age': 39, 'name': 'Homer'}]

More on the Perl Schwartzian transform:

In computer science, the Schwartzian transform is a Perl programming idiom used to improve the efficiency of sorting a list of items. This idiom is appropriate for comparison-based sorting when the ordering is actually based on the ordering of a certain property (the key) of the elements, where computing that property is an intensive operation that should be performed a minimal number of times. The Schwartzian Transform is notable in that it does not use named temporary arrays.

You can use the inbuilt function max() with multiple arguments:

print max(1, 2, 3)

or a list:

list = [1, 2, 3]
print max(list)

or in fact anything iterable.

I use such code, if I have list of strings:

((IList<string>)Table).Count

Windows + Apache 2.4, for example:

1. uncomment ssl_module in your httpd.conf file.

   LoadModule ssl_module modules/mod_ssl.so
   

2. listen 443 port just like 80 port in your httpd.conf file.

   Listen 80
   Listen 443
   

3. uncomment Include Virtual hosts in your httpd.conf file.

   # Virtual hosts
   Include conf/extra/httpd-vhosts.conf
   

4. add VirtualHost in your conf/extra/httpd-vhosts.conf

   <VirtualHost _default_:443>
       DocumentRoot "D:/www"  #your site directory path
       ServerName localhost
       #ServerAlias localhost.com localhost2.com
       SSLEngine on
       SSLCertificateFile "${SRVROOT}/conf/ssl/server.crt"
       SSLCertificateKeyFile "${SRVROOT}/conf/ssl/server.key"
       <Directory "D:/www">
           Options -Indexes +FollowSymLinks +ExecCGI
           AllowOverride All
           Require all granted
       </Directory>
   </VirtualHost>
   

only the port number 443 and SSL...... lines are different from normal http config.

save you config file and restart apache service. then you can visit https://localhost/

The web browser will warn you that it's unsafe at the first time, just choose go on.

You can store the old innerHTML of the div in a variable. Set an interval to check if the old content matches the current content. When this isn't true do something.

Well (a long one) ... if you insist to have $scope access inside a service, you can:

Create a getter/setter service

ngapp.factory('Scopes', function (){
  var mem = {};
  return {
    store: function (key, value) { mem[key] = value; },
    get: function (key) { return mem[key]; }
  };
});

Inject it and store the controller scope in it

ngapp.controller('myCtrl', ['$scope', 'Scopes', function($scope, Scopes) {
  Scopes.store('myCtrl', $scope);
}]);

Now, get the scope inside another service

ngapp.factory('getRoute', ['Scopes', '$http', function(Scopes, $http){
  // there you are
  var $scope = Scopes.get('myCtrl');
}]);

The most widely compatible way of doing this is likely going to be creating a second div under your auto-suggest box the same size as the box itself, nudged a few pixels down and to the right. You can use JS to create and position it, which shouldn't be terribly difficult if you're using a fairly modern framework.

There are a lot of questions here about client side redirect, and I can't spout off on most of them…this one is an exception.

Redirection is not supposed to come from the client…it is supposed to come from the server. If you have no control over the server, you can certainly use Javascript to choose another URL to go to, but…that is not redirection. Redirection is done with 300 status codes at the server, or by plying the META tag in HTML.

You can do date arithmetic by using NSDateComponents. For example:

import Foundation

let comps = NSDateComponents()

comps.minute = 5

let cal = NSCalendar.currentCalendar()

let r = cal.dateByAddingComponents(comps, toDate: NSDate(), options: nil)

It is what you see when you try it in playground

I believe this is controlled by the css color property applied to the element.

As an explanation to Jonathan Fingland's answer:

• multiple conditions in the same predicate ([position()=1 and @location='US']) must be true as a whole
• multiple conditions in consecutive predicates ([position()=1][@location='US']) must be true one after another
• this implies that [position()=1][@location='US'] != [@location='US'][position()=1]
  while [position()=1 and @location='US'] == [@location='US' and position()=1]
• hint: a lone [position()=1] can be abbreviated to [1]

You can build complex expressions in predicates with the Boolean operators "and" and "or", and with the Boolean XPath functions not(), true() and false(). Plus you can wrap sub-expressions in parentheses.

When you say adding antMatchers doesnt help - what do you mean? antMatchers is exactly how you do it. Something like the following should work (obviously changing your URL appropriately):

@Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/authFailure").permitAll()
                .antMatchers("/resources/**").permitAll()
                .anyRequest().authenticated()

If you are still not having any joy, then you will need to provide more details/stacktrace etc.

The documentation for templating is partial, I watched the source.

The _.template function has 3 arguments:

1. String text : the template string
2. Object data : the evaluation data
3. Object settings : local settings, the _.templateSettings is the global settings object

If no data (or null) given, than a render function will be returned. It has 1 argument:

1. Object data : same as the data above

There are 3 regex patterns and 1 static parameter in the settings:

1. RegExp evaluate : "<%code%>" in template string
2. RegExp interpolate : "<%=code%>" in template string
3. RegExp escape : "<%-code%>"
4. String variable : optional, the name of the data parameter in the template string

The code in an evaluate section will be simply evaluated. You can add string from this section with the __p+="mystring" command to the evaluated template, but this is not recommended (not part of the templating interface), use the interpolate section instead of that. This type of section is for adding blocks like if or for to the template.

The result of the code in the interpolate section will added to the evaluated template. If null given back, then empty string will added.

The escape section escapes html with _.escape on the return value of the given code. So its similar than an _.escape(code) in an interpolate section, but it escapes with \ the whitespace characters like \n before it passes the code to the _.escape. I don't know why is that important, it's in the code, but it works well with the interpolate and _.escape - which doesn't escape the white-space characters - too.

By default the data parameter is passed by a with(data){...} statement, but this kind of evaluating is much slower than the evaluating with named variable. So naming the data with the variable parameter is something good...

For example:

var html = _.template(
    "<pre>The \"<% __p+=_.escape(o.text) %>\" is the same<br />" +
        "as the  \"<%= _.escape(o.text) %>\" and the same<br />" +
        "as the \"<%- o.text %>\"</pre>",
    {
        text: "<b>some text</b> and \n it's a line break"
    },
    {
        variable: "o"
    }
);

$("body").html(html);

results

The "<b>some text</b> and 
 it's a line break" is the same
as the "<b>some text</b> and 
 it's a line break" and the same
as the "<b>some text</b> and 
 it's a line break"

You can find here more examples how to use the template and override the default settings: http://underscorejs.org/#template

By template loading you have many options, but at the end you always have to convert the template into string. You can give it as normal string like the example above, or you can load it from a script tag, and use the .html() function of jquery, or you can load it from a separate file with the tpl plugin of require.js.

Another option to build the dom tree with laconic instead of templating.

An HTTP message may have a body of data sent after the header lines. In a response, this is where the requested resource is returned to the client (the most common use of the message body), or perhaps explanatory text if there's an error. In a request, this is where user-entered data or uploaded files are sent to the server.

http://www.tutorialspoint.com/http/http_messages.htm

It helps to trace the exception. For example you are writing some methods in your program and one of your methods causes bug. Then printstack will help you to identify which method causes the bug. Stack will help like this:

First your main method will be called and inserted to stack, then the second method will be called and inserted to the stack in LIFO order and if any error occurs somewhere inside any method then this stack will help to identify that method.

Here is an example of SIGSEGV.

root@pierr-desktop:/opt/playGround# cat test.c
int main()
{
     int * p ;
     * p = 0x1234;
     return 0 ;
}
root@pierr-desktop:/opt/playGround# g++ -o test test.c  
root@pierr-desktop:/opt/playGround# ./test 
Segmentation fault

And here is the detail.

How to handle it?

1. Avoid it as much as possible in the first place.

   Program defensively: use assert(), check for NULL pointer , check for buffer overflow.

   Use static analysis tools to examine your code.

   compile your code with -Werror -Wall.

   Has somebody review your code.

2. When that actually happened.

   Examine you code carefully.

   Check what you have changed since the last time you code run successfully without crash.

   Hopefully, gdb will give you a call stack so that you know where the crash happened.

EDIT : sorry for a rush. It should be *p = 0x1234; instead of p = 0x1234;

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

It sounds like you want an out of source build. There are a couple of ways you can create an out of source build.

1. Do what you were doing, run

   cd /path/to/my/build/folder
   cmake /path/to/my/source/folder
   

   which will cause cmake to generate a build tree in /path/to/my/build/folder for the source tree in /path/to/my/source/folder.

   Once you've created it, cmake remembers where the source folder is - so you can rerun cmake on the build tree with

   cmake /path/to/my/build/folder
   

   or even

   cmake .
   

   if your current directory is already the build folder.

2. For CMake 3.13 or later, use these options to set the source and build folders

   cmake -B/path/to/my/build/folder -S/path/to/my/source/folder
   

3. For older CMake, use some undocumented options to set the source and build folders:

   cmake -B/path/to/my/build/folder -H/path/to/my/source/folder
   

   which will do exactly the same thing as (1), but without the reliance on the current working directory.

CMake puts all of its outputs in the build tree by default, so unless you are liberally using ${CMAKE_SOURCE_DIR} or ${CMAKE_CURRENT_SOURCE_DIR} in your cmake files, it shouldn't touch your source tree.

The biggest thing that can go wrong is if you have previously generated a build tree in your source tree (i.e. you have an in source build). Once you've done this the second part of (1) above kicks in, and cmake doesn't make any changes to the source or build locations. Thus, you cannot create an out-of-source build for a source directory with an in-source build. You can fix this fairly easily by removing (at a minimum) CMakeCache.txt from the source directory. There are a few other files (mostly in the CMakeFiles directory) that CMake generates that you should remove as well, but these won't cause cmake to treat the source tree as a build tree.

Since out-of-source builds are often more desirable than in-source builds, you might want to modify your cmake to require out of source builds:

# Ensures that we do an out of source build

MACRO(MACRO_ENSURE_OUT_OF_SOURCE_BUILD MSG)
     STRING(COMPARE EQUAL "${CMAKE_SOURCE_DIR}"
     "${CMAKE_BINARY_DIR}" insource)
     GET_FILENAME_COMPONENT(PARENTDIR ${CMAKE_SOURCE_DIR} PATH)
     STRING(COMPARE EQUAL "${CMAKE_SOURCE_DIR}"
     "${PARENTDIR}" insourcesubdir)
    IF(insource OR insourcesubdir)
        MESSAGE(FATAL_ERROR "${MSG}")
    ENDIF(insource OR insourcesubdir)
ENDMACRO(MACRO_ENSURE_OUT_OF_SOURCE_BUILD)

MACRO_ENSURE_OUT_OF_SOURCE_BUILD(
    "${CMAKE_PROJECT_NAME} requires an out of source build."
)

The above macro comes from a commonly used module called MacroOutOfSourceBuild. There are numerous sources for MacroOutOfSourceBuild.cmake on google but I can't seem to find the original and it's short enough to include here in full.

Unfortunately cmake has usually written a few files by the time the macro is invoked, so although it will stop you from actually performing the build you will still need to delete CMakeCache.txt and CMakeFiles.

You may find it useful to set the paths that binaries, shared and static libraries are written to - in which case see how do I make cmake output into a 'bin' dir? (disclaimer, I have the top voted answer on that question...but that's how I know about it).

It does work in Firefox (including 2.0.0.20). See http://jsbin.com/akili (add /edit to the url to edit):

<p id="one">One</p>
<a href="#" onclick="document.getElementById('one').id = 'two'; return false">Link2</a>

The first click changes the id to "two", the second click errors because the element with id="one" now can't be found!

Perhaps you have another element already with id="two" (FYI you can't have more than one element with the same id).

Are you trying to submit a form?

Listen to the submit event instead.

This will handle click and enter.

If you must use enter key...

document.querySelector('#txtSearch').addEventListener('keypress', function (e) {
    if (e.key === 'Enter') {
      // code for enter
    }
});

Just set these in php.ini:

upload_max_filesize = 1000M;
post_max_size = 1000M;

You should move it:

Directory.Move(source, destination);

Yes:

RelativeLayout.LayoutParams params= new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT); 
params.addRule(RelativeLayout.BELOW, R.id.below_id);
viewToLayout.setLayoutParams(params);

First, the code creates a new layout params by specifying the height and width. The addRule method adds the equivalent of the xml properly android:layout_below. Then you just call View#setLayoutParams on the view you want to have those params.

There are 2 ways in which you can get the values:-

1. Access the property of the object using dot notation (obj.property) .
2. Access the property of the object by passing in key value for example obj["property"]

I prefer a css only scheme based on horizontal scroll, like tabs on android. This's my solution, just wrap with a class nav-tabs-responsive:

<div class="nav-tabs-responsive">
  <ul class="nav nav-tabs" role="tablist">
    <li>...</li>
  </ul>
</div>

And two css lines:

.nav-tabs { min-width: 600px; }
.nav-tabs-responsive { overflow: auto; }

600px is the point over you will be responsive (you can set it using bootstrap variables)

I understand the accepted answer, and have up-voted it but thought I'd dump my laymen's answer here...

Creating a hash

1. The salt is randomly generated using the function Rfc2898DeriveBytes which generates a hash and a salt. Inputs to Rfc2898DeriveBytes are the password, the size of the salt to generate and the number of hashing iterations to perform. https://msdn.microsoft.com/en-us/library/h83s4e12(v=vs.110).aspx
2. The salt and the hash are then mashed together(salt first followed by the hash) and encoded as a string (so the salt is encoded in the hash). This encoded hash (which contains the salt and hash) is then stored (typically) in the database against the user.

Checking a password against a hash

To check a password that a user inputs.

1. The salt is extracted from the stored hashed password.
2. The salt is used to hash the users input password using an overload of Rfc2898DeriveBytes which takes a salt instead of generating one. https://msdn.microsoft.com/en-us/library/yx129kfs(v=vs.110).aspx
3. The stored hash and the test hash are then compared.

The Hash

Under the covers the hash is generated using the SHA1 hash function (https://en.wikipedia.org/wiki/SHA-1). This function is iteratively called 1000 times (In the default Identity implementation)

Why is this secure

• Random salts means that an attacker can’t use a pre-generated table of hashs to try and break passwords. They would need to generate a hash table for every salt. (Assuming here that the hacker has also compromised your salt)
• If 2 passwords are identical they will have different hashes. (meaning attackers can’t infer ‘common’ passwords)
• Iteratively calling SHA1 1000 times means that the attacker also needs to do this. The idea being that unless they have time on a supercomputer they won’t have enough resource to brute force the password from the hash. It would massively slow down the time to generate a hash table for a given salt.

its super easy.

You'll need each machine to have it's own copy of ElasticSearch (simply copy the one you have now) -- the reason is that each machine / node whatever is going to keep it's own files that are sharded accross the cluster.

The only thing you really need to do is edit the config file to include the name of the cluster.

If all machines have the same cluster name elasticsearch will do the rest automatically (as long as the machines are all on the same network)

Read here to get you started: https://www.elastic.co/guide/en/elasticsearch/guide/current/deploy.html

When you create indexes (where the data goes) you define at that time how many replicas you want (they'll be distributed around the cluster)

I got into this mess twice and after searching long and hard and following what others did absolutely nothing worked for me but to uninstall and install IIS back once on Windows 7 machine and then on Windows server 2012 R2.

If you want to update branch that is not currently checked out you can do:

git fetch -f origin rbranch:lbranch

At first you must consider that if your activity which I called A extends another activity (B) and in both of

them you want to use onbackpressed function then every code you have in B runs in A too. So if you want to separate these you should separate them. It means that A should not extend B , then you can have onbackpressed separately for each of them.

If you don't want to reinvent the wheel you may try plupload.com

Above answers are pretty sufficient. Additional to the onChange, if you upload a file using drag and drop events, you can get the file in drop event by accessing eventArgs.dataTransfer.files.

wrong code:$("#myParagraph").css({"backgroundColor":"black","color":"white");

its missing "}" after white"

change it to this

 $("#myParagraph").css({"background-color":"black","color":"white"});

I discovered that you can also do Device Manager -> Update Driver Software -> Browse my computer for driver software -> Let me pick from a list of device drivers on my computer -> Android Phone -> [ADB driver version 6 near top of list... sorry, I can't remember exact name]

As soon as I did that, it connected, and I was able to sideload version 4.2 on Windows 7 64 bit.

The error I had in XCode was "iOS version lower than deployment target", which I didn't know how to fix. The error was displayed where the iPhone should have been indicated as a Device (upper left). I selected the project in Project Navigator and noticed that the iOS Deployment Target was set to 11.3 but when I checked my iPhone it was set to 11.2.1 (or something lower than 11.3). So I opened Settings on the phone, scrolled down to General and tapped Software Update. Since the update said it was scheduled but didn't start, I decided to take the SIM card out of my other phone and put it in the iPhone I was using for testing. Then the upgrade started quickly. After the Update finished on the phone, however, XCode still didn't recognize the phone. I unplugged the USB cable but didn't hear any sound, so I plugged it into another USB port on the computer and then heard a sound. Then XCode noticed the phone. So the problems were that the iPhone didn't inform me that I had an Update (or I ignored it and forgot about it) and it may have needed the SIM card, and I had a bad USB connection.

Sorry for resurrecting an old thread, but I was with the same problem today. The simplest way that I have found is the following:

# Expand right side of clipping rect to make room for the legend
par(xpd=T, mar=par()$mar+c(0,0,0,6))

# Plot graph normally
plot(1:3, rnorm(3), pch = 1, lty = 1, type = "o", ylim=c(-2,2))
lines(1:3, rnorm(3), pch = 2, lty = 2, type="o")

# Plot legend where you want
legend(3.2,1,c("group A", "group B"), pch = c(1,2), lty = c(1,2))

# Restore default clipping rect
par(mar=c(5, 4, 4, 2) + 0.1)

If numpy >= 1.5, you can do:

# note that the filename is enclosed with double quotes,
# example "filename.txt"

numpy.savetxt("filename", a, newline=" ")

Edit

several 1D arrays with same length

a = numpy.array([1,2,3])
b = numpy.array([4,5,6])
numpy.savetxt(filename, (a,b), fmt="%d")

# gives:
# 1 2 3
# 4 5 6

several 1D arrays with variable length

a = numpy.array([1,2,3])
b = numpy.array([4,5])

with open(filename,"w") as f:
    f.write("\n".join(" ".join(map(str, x)) for x in (a,b)))

# gives:
# 1 2 3
# 4 5

here's a simpler way to go about it. this solution doesn't use a config dictionary and uses a rotation file handler, like so:

import logging
from logging.handlers import RotatingFileHandler

logging.basicConfig(handlers=[RotatingFileHandler(filename=logpath+filename,
                     mode='w', maxBytes=512000, backupCount=4)], level=debug_level,
                     format='%(levelname)s %(asctime)s %(message)s', 
                    datefmt='%m/%d/%Y%I:%M:%S %p')

logger = logging.getLogger('my_logger')

or like so:

import logging
from logging.handlers import RotatingFileHandler

handlers = [
            RotatingFileHandler(filename=logpath+filename, mode='w', maxBytes=512000, 
                                backupCount=4)
           ]
logging.basicConfig(handlers=handlers, level=debug_level, 
                    format='%(levelname)s %(asctime)s %(message)s', 
                    datefmt='%m/%d/%Y%I:%M:%S %p')

logger = logging.getLogger('my_logger')

the handlers variable needs to be an iterable. logpath+filename and debug_level are just variables holding the respective info. of course, the values for the function params are up to you.

the first time i was using the logging module i made the mistake of writing the following, which generates an OS file lock error (the above is the solution to that):

import logging
from logging.handlers import RotatingFileHandler

logging.basicConfig(filename=logpath+filename, level=debug_level, format='%(levelname)s %(asctime)s %(message)s', datefmt='%m/%d/%Y
 %I:%M:%S %p')

logger = logging.getLogger('my_logger')
logger.addHandler(RotatingFileHandler(filename=logpath+filename, mode='w', 
                  maxBytes=512000, backupCount=4))

and Bob's your uncle!

Best way that you should go every time for creating json in php is to first convert values in ASSOCIATIVE array.

After that just simply encode using json_encode($associativeArray). I think it is the best way to create json in php because whenever we are fetching result form sql query in php most of the time we got values using fetch_assoc function, which also return one associative array.

$associativeArray = array();
$associativeArray ['FirstValue'] = 'FirstValue';

... etc.

After that.

json_encode($associativeArray);

ProcessLifecycleOwner seems to be a promising solution also.

ProcessLifecycleOwner will dispatch ON_START, ON_RESUME events, as a first activity moves through these events. ON_PAUSE, ON_STOP, events will be dispatched with a delay after a last activity passed through them. This delay is long enough to guarantee that ProcessLifecycleOwner won't send any events if activities are destroyed and recreated due to a configuration change.

An implementation can be as simple as

class AppLifecycleListener : LifecycleObserver {

    @OnLifecycleEvent(Lifecycle.Event.ON_START)
    fun onMoveToForeground() { // app moved to foreground
    }

    @OnLifecycleEvent(Lifecycle.Event.ON_STOP)
    fun onMoveToBackground() { // app moved to background
    }
}

// register observer
ProcessLifecycleOwner.get().lifecycle.addObserver(AppLifecycleListener())

According to source code, current delay value is 700ms.

Also using this feature requires the dependencies:

implementation "androidx.lifecycle:lifecycle-extensions:$lifecycleVersion"

try this

animals = ['bear' , 'python' , 'peacock', 'kangaroo' , 'whale' , 'platypus']

# print "The first (1st) animal is at 0 and is a bear." 

for i in range(len(animals)):
    print "The %d animal is at %d and is a %s" % (i+1 ,i, animals[i])

# "The animal at 0 is the 1st animal and is a bear."

for i in range(len(animals)):
    print "The animal at %d is the %d and is a %s " % (i, i+1, animals[i])

Fot people who have tried EVERYTHING and just CANNOT get the error details to show, like me, it's a good idea to check the different levels of configuration. I have a config file on Website level and on Application level (inside the website) check both. Also, as it turned out, I had Detailed Errors disabled on the highest node in IIS (just underneath Start Page, it has the name that is the same as the webservers computername). Check the Error Pages there.

        // no default cookie, so we need to redirect to top level and set
        $url = $_SERVER['REQUEST_URI'];
        if (strpos($url,"?") === false) $url .= "?";
        else $url .= "&";
        $url .= "setdefaultcookie=1";
        echo "<html>\n<body>\n<script>\ntop.location.href='".$url."';\n</script></body></html>";

You'll need to deal with File System Object. See this OpenTextFile method sample.

We don't commit the binary file (*.suo), but we commit the .user file. The .user file contains for example the start options for debugging the project. You can find the start options in the properties of the project in the tab "Debug". We used NUnit in some projects and configured the nunit-gui.exe as the start option for the project. Without the .user file, each team member would have to configure it separately.

Hope this helps.

When you use position:fixed CSS rule and try to apply top/left/right/bottom it position the element relative to window.

A workaround is to use margin properties instead of top/left/right/bottom

Boxing and Unboxing are specifically used to treat value-type objects as reference-type; moving their actual value to the managed heap and accessing their value by reference.

Without boxing and unboxing you could never pass value-types by reference; and that means you could not pass value-types as instances of Object.

As discussed above these are the venn diagrams of all the joins.

I have created a function to store URL of previous page

//functions.php

function set_previous_page_url(){

    $current_url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}"; 
    $previous_url = $_SERVER['HTTP_REFERER'];
    if (!($current_url === $previous_url)){
        $_SESSION['redirect_url'] = $previous_url;
    }
    if(isset($_SESSION['redirect_url'])){
        $url = $_SESSION['redirect_url'];
        return $url;

    } else {
        $url = "index.php";
        return $url;
    }
}

And call this function in login.php

// login.php

<?php
// set previous page url to redirect after login
$url = set_previous_page_url();

if(ifItIsMethod('post')){
    if(isset($_POST['username']) && isset($_POST['password'])){
        if (login_user($_POST['username'], $_POST['password'])) {
            redirect($url);
            //unset session defined in set_previous_page_url() function
            if(isset($_SESSION['redirect_url'])){
                unset($_SESSION['redirect_url']);
            }

        } 
    }
}
?>

How I was doing it until now:

php artisan make:model Customer
php artisan make:controller CustomersController --resource

Apparently, there’s a quicker way:

php artisan make:controller CustomersController --model=Customer

Commands may be abbreviated, so long as they are unambiguous.
e.g. 'gem i rake' is short for 'gem install rake'.
kirti@kirti-Aspire-5733Z:~$ 

Now from the above I can see the command environment is helpful. So I would do:

kirti@kirti-Aspire-5733Z:~$ gem help environment
Usage: gem environment [arg] [options]


  Common Options:
    -h, --help                       Get help on this command
    -V, --[no-]verbose               Set the verbose level of output
    -q, --quiet                      Silence commands
        --config-file FILE           Use this config file instead of default
        --backtrace                  Show stack backtrace on errors
        --debug                      Turn on Ruby debugging


  Arguments:
    packageversion  display the package version
    gemdir          display the path where gems are installed
    gempath         display path used to search for gems
    version         display the gem format version
    remotesources   display the remote gem servers
    platform        display the supported gem platforms
    <omitted>       display everything

  Summary:
    Display information about the RubyGems environment

  Description:
    The RubyGems environment can be controlled through command line arguments,
    gemrc files, environment variables and built-in defaults.

    Command line argument defaults and some RubyGems defaults can be set in a
    ~/.gemrc file for individual users and a /etc/gemrc for all users. These
    files are YAML files with the following YAML keys:

      :sources: A YAML array of remote gem repositories to install gems from
      :verbose: Verbosity of the gem command. false, true, and :really are the
                levels
      :update_sources: Enable/disable automatic updating of repository metadata
      :backtrace: Print backtrace when RubyGems encounters an error
      :gempath: The paths in which to look for gems
      :disable_default_gem_server: Force specification of gem server host on
    push
      <gem_command>: A string containing arguments for the specified gem command

    Example:

      :verbose: false
      install: --no-wrappers
      update: --no-wrappers
      :disable_default_gem_server: true

    RubyGems' default local repository can be overridden with the GEM_PATH and
    GEM_HOME environment variables. GEM_HOME sets the default repository to
    install into. GEM_PATH allows multiple local repositories to be searched for
    gems.

    If you are behind a proxy server, RubyGems uses the HTTP_PROXY,
    HTTP_PROXY_USER and HTTP_PROXY_PASS environment variables to discover the
    proxy server.

    If you would like to push gems to a private gem server the RUBYGEMS_HOST
    environment variable can be set to the URI for that server.

    If you are packaging RubyGems all of RubyGems' defaults are in
    lib/rubygems/defaults.rb.  You may override these in
    lib/rubygems/defaults/operating_system.rb
kirti@kirti-Aspire-5733Z:~$ 

Finally to show you what you asked, I would do:

kirti@kirti-Aspire-5733Z:~$ gem environment gemdir
/home/kirti/.rvm/gems/ruby-2.0.0-p0
kirti@kirti-Aspire-5733Z:~$ gem environment gempath
/home/kirti/.rvm/gems/ruby-2.0.0-p0:/home/kirti/.rvm/gems/ruby-2.0.0-p0@global
kirti@kirti-Aspire-5733Z:~$ 

Put the jquery js link before the bootstrap js link like so:

<script type="text/javascript" src="Scripts/jquery-2.1.1.min.js"></script>
<script type="text/javascript" src="Scripts/bootstrap.min.js"></script>

instead of:

<script type="text/javascript" src="Scripts/bootstrap.min.js"></script>
<script type="text/javascript" src="Scripts/jquery-2.1.1.min.js"></script>

I believe, by default, boto picks the region which is set in aws cli. You can run command #aws configure and press enter (it shows what creds you have set in aws cli with region)twice to confirm your region.

Alternatively, you can pass an empty tick position and label as

# for matplotlib.pyplot
# ---------------------
plt.xticks([], [])
# for axis object
# ---------------
# from Anakhand May 5 at 13:08
# for major ticks
ax.set_xticks([])
# for minor ticks
ax.set_xticks([], minor=True)

I just found the answer here

It says: It is possible to retrieve the location of a view by invoking the methods getLeft() and getTop(). The former returns the left, or X, coordinate of the rectangle representing the view. The latter returns the top, or Y, coordinate of the rectangle representing the view. These methods both return the location of the view relative to its parent. For instance, when getLeft() returns 20, that means the view is located 20 pixels to the right of the left edge of its direct parent.

so use:

view.getLeft(); // to get the location of X from left to right
view.getRight()+; // to get the location of Y from right to left

Make it simple-
At the end of the day when you are confused choosing containers in C++ use this flow chart image ( Say thanks to me ) :-

Vector-

1. vector is based on contagious memory
2. vector is way to go for small data-set
3. vector perform fastest while traversing on data-set
4. vector insertion deletion is slow on huge data-set but fast for very small

List-

1. list is based on heap memory
2. list is way to go for very huge data-set
3. list is comparatively slow on traversing small data-set but fast at huge data-set
4. list insertion deletion is fast on huge data-set but slow on smaller ones

No need to install 3rd party extensions!

There exists the javascript-snippet, which you can add as browser-bookmark and then activate on any site to track & modify the requests. It looks like:

For further instructions, review the github page.

You code is correct. replace items with .items as below

<script>
  var n = $(".items").css("left");
  if(n == -900){
    $(".items span").fadeOut("slow");
  }
</script>

Before reconfiguring the global excludes file, you might want to check what it's currently configured to, using this command:

git config --get core.excludesfile

In my case, when I ran it I saw my global excludes file was configured to

~/.gitignore_global

Be sure to fully qualify your sheets with which workbook they are referencing!

 mainWB.Sheets.Add(After:=mainWB.Sheets(mainWB.Sheets.Count)).Name = new_sheet_name

First, install the URL Rewrite from a download or from the Web Platform Installer. Second, restart IIS. And, finally, close IIS and open again. The last step worked for me.

As already mentioned, the only way is to use a plugin that replaces <select> functionality.

A list of jQuery plugins: http://plugins.jquery.com/tag/select/

Take a look at the example using Select2 plugin: http://jsfiddle.net/swsLokfj/23/

Well 12 and 12.00 have exactly the same representation as double values. Are you trying to end up with a double or something else? (For example, you could cast to int, if you were convinced the value would be in the right range, and if the truncation effect is what you want.)

You might want to look at these methods too:

• Math.Floor
• Math.Ceiling
• Math.Round (with variations for how to handle midpoints)
• Math.Truncate

Run this command in terminal to remove simulators that can't be accessed from the current version of Xcode in use.

xcrun simctl delete unavailable

Also if you're looking to reclaim simulator related space Michael Tsai found that deleting sim logs saved him 30 GB.

Don't forget that the wrap can be done with Function.prototype.bind, giving you an "all-native" function.

var aMax = Math.max.apply.bind(Math.max, Math);
aMax([1, 2, 3, 4, 5]); // 5

for classes you can use:

div[class^="jander"]

I think this should work. It might be off on the slashes. Not sure if they are needed or not.

string url = Request.ApplicationPath + "/" + photosLocation + "/" + files[0];

I'm guessing Laravel can't determine the plural form of the word you used for your table name.

Just specify your table in the model as such:

class Cotizacion extends Model{
    public $table = "cotizacion";

They don't do the same thing. The first one works if obj is of type ClassA or of some subclass of ClassA. The second one will only match objects of type ClassA. The second one will be faster since it doesn't have to check the class hierarchy.

For those who want to know the reason, but don't want to read the article referenced in is vs typeof.

A message has a header part and a message body separated by a blank line. The blank line is ALWAYS needed even if there is no message body. The header starts with a command and has additional lines of key value pairs separated by a colon and a space. If there is a message body, it can be anything you want it to be.

Lines in the header and the blank line at the end of the header must end with a carraige return and linefeed pair (see HTTP header line break style) so that's why those lines have \r\n at the end.

A URL has the form of http://host:port/path?query_string

There are two main ways of submitting a request to a website:

• GET: The query string is optional but, if specified, must be reasonably short. Because of this the header could just be the GET command and nothing else. A sample message could be:

  GET /path?query_string HTTP/1.0\r\n
  \r\n
  

• POST: What would normally be in the query string is in the body of the message instead. Because of this the header needs to include the Content-Type: and Content-Length: attributes as well as the POST command. A sample message could be:

  POST /path HTTP/1.0\r\n
  Content-Type: text/plain\r\n
  Content-Length: 12\r\n
  \r\n
  query_string
  

So, to answer your question: if the URL you are interested in POSTing to is http://api.somesite.com/apikey=ARG1&command=ARG2 then there is no body or query string and, consequently, no reason to POST because there is nothing to put in the body of the message and so nothing to put in the Content-Type: and Content-Length:

I guess you could POST if you really wanted to. In that case your message would look like:

POST /apikey=ARG1&command=ARG2 HTTP/1.0\r\n
\r\n

So to send the message the C program needs to:

• create a socket
• lookup the IP address
• open the socket
• send the request
• wait for the response
• close the socket

The send and receive calls won't necessarily send/receive ALL the data you give them - they will return the number of bytes actually sent/received. It is up to you to call them in a loop and send/receive the remainder of the message.

What I did not do in this sample is any sort of real error checking - when something fails I just exit the program. Let me know if it works for you:

#include <stdio.h> /* printf, sprintf */
#include <stdlib.h> /* exit */
#include <unistd.h> /* read, write, close */
#include <string.h> /* memcpy, memset */
#include <sys/socket.h> /* socket, connect */
#include <netinet/in.h> /* struct sockaddr_in, struct sockaddr */
#include <netdb.h> /* struct hostent, gethostbyname */

void error(const char *msg) { perror(msg); exit(0); }

int main(int argc,char *argv[])
{
    /* first what are we going to send and where are we going to send it? */
    int portno =        80;
    char *host =        "api.somesite.com";
    char *message_fmt = "POST /apikey=%s&command=%s HTTP/1.0\r\n\r\n";

    struct hostent *server;
    struct sockaddr_in serv_addr;
    int sockfd, bytes, sent, received, total;
    char message[1024],response[4096];

    if (argc < 3) { puts("Parameters: <apikey> <command>"); exit(0); }

    /* fill in the parameters */
    sprintf(message,message_fmt,argv[1],argv[2]);
    printf("Request:\n%s\n",message);

    /* create the socket */
    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    if (sockfd < 0) error("ERROR opening socket");

    /* lookup the ip address */
    server = gethostbyname(host);
    if (server == NULL) error("ERROR, no such host");

    /* fill in the structure */
    memset(&serv_addr,0,sizeof(serv_addr));
    serv_addr.sin_family = AF_INET;
    serv_addr.sin_port = htons(portno);
    memcpy(&serv_addr.sin_addr.s_addr,server->h_addr,server->h_length);

    /* connect the socket */
    if (connect(sockfd,(struct sockaddr *)&serv_addr,sizeof(serv_addr)) < 0)
        error("ERROR connecting");

    /* send the request */
    total = strlen(message);
    sent = 0;
    do {
        bytes = write(sockfd,message+sent,total-sent);
        if (bytes < 0)
            error("ERROR writing message to socket");
        if (bytes == 0)
            break;
        sent+=bytes;
    } while (sent < total);

    /* receive the response */
    memset(response,0,sizeof(response));
    total = sizeof(response)-1;
    received = 0;
    do {
        bytes = read(sockfd,response+received,total-received);
        if (bytes < 0)
            error("ERROR reading response from socket");
        if (bytes == 0)
            break;
        received+=bytes;
    } while (received < total);

    if (received == total)
        error("ERROR storing complete response from socket");

    /* close the socket */
    close(sockfd);

    /* process response */
    printf("Response:\n%s\n",response);

    return 0;
}

Like the other answer pointed out, 4096 bytes is not a very big response. I picked that number at random assuming that the response to your request would be short. If it can be big you have two choices:

• read the Content-Length: header from the response and then dynamically allocate enough memory to hold the whole response.
• write the response to a file as the pieces arrive

Additional information to answer the question asked in the comments:

What if you want to POST data in the body of the message? Then you do need to include the Content-Type: and Content-Length: headers. The Content-Length: is the actual length of everything after the blank line that separates the header from the body.

Here is a sample that takes the following command line arguments:

• host
• port
• command (GET or POST)
• path (not including the query data)
• query data (put into the query string for GET and into the body for POST)
• list of headers (Content-Length: is automatic if using POST)

So, for the original question you would run:

a.out api.somesite.com 80 GET "/apikey=ARG1&command=ARG2"

And for the question asked in the comments you would run:

a.out api.somesite.com 80 POST / "name=ARG1&value=ARG2" "Content-Type: application/x-www-form-urlencoded"

defaultMember already is an alias - it doesn't need to be the name of the exported function/thing. Just do

import alias from 'my-module';

Alternatively you can do

import {default as alias} from 'my-module';

but that's rather esoteric.

You can extract the different parts out quite neatly using a regex pattern:

In [11]: df.row.str.extract('(?P<fips>\d{5})((?P<state>[A-Z ]*$)|(?P<county>.*?), (?P<state_code>[A-Z]{2}$))')
Out[11]: 
    fips                    1           state           county state_code
0  00000        UNITED STATES   UNITED STATES              NaN        NaN
1  01000              ALABAMA         ALABAMA              NaN        NaN
2  01001   Autauga County, AL             NaN   Autauga County         AL
3  01003   Baldwin County, AL             NaN   Baldwin County         AL
4  01005   Barbour County, AL             NaN   Barbour County         AL

[5 rows x 5 columns]

To explain the somewhat long regex:

(?P<fips>\d{5})

• Matches the five digits (\d) and names them "fips".

The next part:

((?P<state>[A-Z ]*$)|(?P<county>.*?), (?P<state_code>[A-Z]{2}$))

Does either (|) one of two things:

(?P<state>[A-Z ]*$)

• Matches any number (*) of capital letters or spaces ([A-Z ]) and names this "state" before the end of the string ($),

or

(?P<county>.*?), (?P<state_code>[A-Z]{2}$))

• matches anything else (.*) then
• a comma and a space then
• matches the two digit state_code before the end of the string ($).

In the example:
Note that the first two rows hit the "state" (leaving NaN in the county and state_code columns), whilst the last three hit the county, state_code (leaving NaN in the state column).

Here's a good tutorial on Powershell params:

PowerShell ABC's - P is for Parameters

Basically, you should use a param statement on the first line of the script

param([type]$p1 = , [type]$p2 = , ...)

or use the $args built-in variable, which is auto-populated with all of the args.

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

string type is a reference type, therefore it is nullable by default. You can only use Nullable<T> with value types.

public struct Nullable<T> where T : struct

Which means that whatever type is replaced for the generic parameter, it must be a value type.

syntax of date_format:

SELECT date_format(date_born, '%m/%d/%Y' ) as my_date FROM date_tbl

    '%W %D %M %Y %T'    -> Wednesday 5th May 2004 23:56:25
    '%a %b %e %Y %H:%i' -> Wed May 5 2004 23:56
    '%m/%d/%Y %T'       -> 05/05/2004 23:56:25
    '%d/%m/%Y'          -> 05/05/2004
    '%m-%d-%y'          -> 04-08-13

You use new to perform dynamic allocation. It returns a pointer that points to the dynamically allocated object.

You have no reason to use new, since A is an automatic variable. You can simply initialise A using its constructor:

vector<vector<int> > A(dimension, vector<int>(dimension));

x=[1,2,3,4,5]
sum=0
for s in range(0,len(x)):
   sum=sum+x[s]
print sum

Build.SERIAL can be empty or sometimes return a different value (proof 1, proof 2) than what you can see in your device's settings.

If you want a more complete and robust solution, I've compiled every possible solution I could found in a single gist. Here's a simplified version of it :

public static String getSerialNumber() {
    String serialNumber;

    try {
        Class<?> c = Class.forName("android.os.SystemProperties");
        Method get = c.getMethod("get", String.class);

        serialNumber = (String) get.invoke(c, "gsm.sn1");
        if (serialNumber.equals(""))
            serialNumber = (String) get.invoke(c, "ril.serialnumber");
        if (serialNumber.equals(""))
            serialNumber = (String) get.invoke(c, "ro.serialno");
        if (serialNumber.equals(""))
            serialNumber = (String) get.invoke(c, "sys.serialnumber");
        if (serialNumber.equals(""))
            serialNumber = Build.SERIAL;

        // If none of the methods above worked
        if (serialNumber.equals(""))
            serialNumber = null;
    } catch (Exception e) {
        e.printStackTrace();
        serialNumber = null;
    }

    return serialNumber;
}

I try to update the gist regularly whenever I can test on a new device or Android version. Contributions are welcome too.

For those who are still looking for an answer. Here is a recursive approach to get the paths in a dictionary.

import os


def list_files(startpath):
    for root, dirs, files in os.walk(startpath):
        dir_content = []
        for dir in dirs:
            go_inside = os.path.join(startpath, dir)
            dir_content.append(list_files(go_inside))
        files_lst = []
        for f in files:
            files_lst.append(f)
        return {'name': root, 'files': files_lst, 'dirs': dir_content}

Update: From now on, I use .collapse and $('.collapse').show().

For Bootstrap 4 Alpha 6

For Bootstrap 4 you have to use .hidden-xs-up.

https://v4-alpha.getbootstrap.com/layout/responsive-utilities/#available-classes

The .hidden-*-up classes hide the element when the viewport is at the given breakpoint or wider. For example, .hidden-md-up hides an element on medium, large, and extra-large viewports.

There is also hidden HTML5 attribute.

https://v4-alpha.getbootstrap.com/content/reboot/#html5-hidden-attribute

HTML5 adds a new global attribute named [hidden], which is styled as display: none by default. Borrowing an idea from PureCSS, we improve upon this default by making [hidden] { display: none !important; } to help prevent its display from getting accidentally overridden. While [hidden] isn’t natively supported by IE10, the explicit declaration in our CSS gets around that problem.

<input type="text" hidden>

There is also .invisible which does affect the layout.

https://v4-alpha.getbootstrap.com/utilities/invisible-content/

The .invisible class can be used to toggle only the visibility of an element, meaning its display is not modified and the element can still affect the flow of the document.

You can use gcc/clang's unused attribute, however I use these macros in a header to avoid having gcc specific attributes all over the source, also having __attribute__ everywhere is a bit verbose/ugly.

#ifdef __GNUC__
#  define UNUSED(x) UNUSED_ ## x __attribute__((__unused__))
#else
#  define UNUSED(x) UNUSED_ ## x
#endif

#ifdef __GNUC__
#  define UNUSED_FUNCTION(x) __attribute__((__unused__)) UNUSED_ ## x
#else
#  define UNUSED_FUNCTION(x) UNUSED_ ## x
#endif

Then you can do...

void foo(int UNUSED(bar)) { ... }

I prefer this because you get an error if you try use bar in the code anywhere so you can't leave the attribute in by mistake.

and for functions...

static void UNUSED_FUNCTION(foo)(int bar) { ... }

Note 1):
As far as I know, MSVC doesn't have an equivalent to __attribute__((__unused__)).

Note 2):
The UNUSED macro won't work for arguments which contain parenthesis,
so if you have an argument like float (*coords)[3] you can't do,
float UNUSED((*coords)[3]) or float (*UNUSED(coords))[3], This is the only downside to the UNUSED macro I found so far, in these cases I fall back to (void)coords;

import numpy as np 

... ## other code

some list comprehension

t=[nodel[ nodenext[i][j] ] for j in idx]
            #for each link, find the node lables 
            #t is the list of node labels 

Convert the list to a numpy array using the array method specified in the numpy library.

t=np.array(t)

You might want to create static class which will contain all the fonts. That way, you won't create the font multiple times which might impact badly on performance. Just make sure that you create a sub-folder called "fonts" under "assets" folder.

Do something like:

public class CustomFontsLoader {

public static final int FONT_NAME_1 =   0;
public static final int FONT_NAME_2 =   1;
public static final int FONT_NAME_3 =   2;

private static final int NUM_OF_CUSTOM_FONTS = 3;

private static boolean fontsLoaded = false;

private static Typeface[] fonts = new Typeface[3];

private static String[] fontPath = {
    "fonts/FONT_NAME_1.ttf",
    "fonts/FONT_NAME_2.ttf",
    "fonts/FONT_NAME_3.ttf"
};


/**
 * Returns a loaded custom font based on it's identifier. 
 * 
 * @param context - the current context
 * @param fontIdentifier = the identifier of the requested font
 * 
 * @return Typeface object of the requested font.
 */
public static Typeface getTypeface(Context context, int fontIdentifier) {
    if (!fontsLoaded) {
        loadFonts(context);
    }
    return fonts[fontIdentifier];
}


private static void loadFonts(Context context) {
    for (int i = 0; i < NUM_OF_CUSTOM_FONTS; i++) {
        fonts[i] = Typeface.createFromAsset(context.getAssets(), fontPath[i]);
    }
    fontsLoaded = true;

}
}

This way, you can get the font from everywhere in your application.

To answer the updated part of your question: to style the drawer icon/arrow, you have two options:

Style the arrow itself

To do this, override drawerArrowStyle in your theme like so:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="drawerArrowStyle">@style/MyTheme.DrawerArrowToggle</item>
</style>
<style name="MyTheme.DrawerArrowToggle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="color">@android:color/holo_purple</item>
    <!-- ^ this will make the icon purple -->
</style>

This is probably not what you want, because the ActionBar itself should have consistent styling with the arrow, so, most probably, you want the option two:

Theme the ActionBar/Toolbar

Override the android:actionBarTheme (actionBarTheme for appcompat) attribute of the global application theme with your own theme (which you probably should derive from ThemeOverlay.Material.ActionBar/ThemeOverlay.AppCompat.ActionBar) like so:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="actionBarTheme">@style/MyTheme.ActionBar</item>
</style>
<style name="MyTheme.ActionBar" parent="ThemeOverlay.AppCompat.ActionBar">
    <item name="android:textColorPrimary">@android:color/white</item>
    <!-- ^ this will make text and arrow white -->
    <!-- you can also override drawerArrowStyle here -->
</style>

An important note here is that when using a custom layout with a Toolbar instead of stock ActionBar implementation (e.g. if you're using the DrawerLayout-NavigationView-Toolbar combo to achieve the Material-style drawer effect where it's visible under translucent statusbar), the actionBarTheme attribute is obviosly not picked up automatically (because it's meant to be taken care of by the AppCompatActivity for the default ActionBar), so for your custom Toolbar don't forget to apply your theme manually:

<!--inside your custom layout with DrawerLayout
and NavigationView or whatever -->
<android.support.v7.widget.Toolbar
        ...
        app:theme="?actionBarTheme">

-- this will resolve to either AppCompat's default ThemeOverlay.AppCompat.ActionBar or your override if you set the attribute in your derived theme.

PS a little comment about the drawerArrowStyle override and the spinBars attribute -- which a lot of sources suggest should be set to true to get the drawer/arrow animation. Thing is, spinBars it is true by default in AppCompat (check out the Base.Widget.AppCompat.DrawerArrowToggle.Common style), you don't have to override actionBarTheme at all to get the animation working. You get the animation even if you do override it and set the attribute to false, it's just a different, less twirly animation. The important thing here is to use ActionBarDrawerToggle, it's what pulls in the fancy animated drawable.

1. You must set Protected Mode settings for each zone to be the same value.
2. Enhanced Protected Mode for all zones must be same. (I prefer it to be disabled as this is the requirement for IE 10 and higher.)

Additionally, "Enhanced Protected Mode" must be disabled for IE 10 and higher. This option is found in the Advanced tab of the Internet Options dialog.

How to do above steps???

Have look at this video: http://screencast.com/t/5nlxsrje4I . I have showed the steps.

I had to re-run ng update @angular/cli for angular-cli.json to be changed to angular.json

As many mentioned in comments to @DMTinter's post, the OP was asking about the number ("amount") of characters changing. He was also asking about CSS, but as @Alexander indicated, "it is not possible with only CSS". As far as I can tell, that seems to be true at this time, so it also seems logical that people would want to know the next best thing.

I'm not particularly proud of this, but it does work. Seems like an excessive amount of code to accomplish it. This is the core:

function fitText(el){
  var text = el.text();
  var fsize = parseInt(el.css('font-size'));
  var measured = measureText(text, fsize);

  if (measured.width > el.width()){
    console.log('reducing');
    while(true){
      fsize = parseInt(el.css('font-size'));
      var m = measureText(text, fsize );
      if(m.width > el.width()){
        el.css('font-size', --fsize + 'px');
      }
      else{
        break;
      }
    }
  }
  else if (measured.width < el.width()){
    console.log('increasing');
    while(true){
      fsize = parseInt(el.css('font-size'));
      var m = measureText(text, fsize);
      if(m.width < el.width()-4){ // not sure why -4 is needed (often)
        el.css('font-size', ++fsize + 'px');
      }
      else{
        break;
      }
    }
  }
}

Here's a JS Bin: http://jsbin.com/pidavon/edit?html,css,js,console,output
Please suggest possible improvements to it (I'm not really interested in using canvas to measure the text...seems like too much overhead(?)).

Thanks to @Pete for measureText function: https://stackoverflow.com/a/4032497/442665

We were using a static SystemTime object, but ran into problems running parallel unit tests. I attempted to use Henk van Boeijen's solution but had problems across spawned asynchronous threads, ended up using using AsyncLocal in a manner similar to this below:

public static class Clock
{
    private static Func<DateTime> _utcNow = () => DateTime.UtcNow;

    static AsyncLocal<Func<DateTime>> _override = new AsyncLocal<Func<DateTime>>();

    public static DateTime UtcNow => (_override.Value ?? _utcNow)();

    public static void Set(Func<DateTime> func)
    {
        _override.Value = func;
    }

    public static void Reset()
    {
        _override.Value = null;
    }
}

You are implementing LocationListener in your activity MainActivity. The call for concurrent location updates will therefor be like this:

mLocationClient.requestLocationUpdates(mLocationRequest, this);

Be sure that the LocationListener you're implementing is from the google api, that is import this:

import com.google.android.gms.location.LocationListener;

and not this:

import android.location.LocationListener;

and it should work just fine.

It's also important that the LocationClient really is connected before you do this. I suggest you don't call it in the onCreate or onStart methods, but in onResume. It is all explained quite well in the tutorial for Google Location Api: https://developer.android.com/training/location/index.html

Use the -s option BEFORE the command to specify the device, for example:

adb -s 7f1c864e shell

See also http://developer.android.com/tools/help/adb.html#directingcommands

First of all, they both are the non-scalar objects (also known as a compound objects) in Python.

• Tuples, ordered sequence of elements (which can contain any object with no aliasing issue)
  • Immutable (tuple, int, float, str)
  • Concatenation using + (brand new tuple will be created of course)
  • Indexing
  • Slicing
  • Singleton (3,) # -> (3) instead of (3) # -> 3
• List (Array in other languages), ordered sequence of values
  • Mutable
  • Singleton [3]
  • Cloning new_array = origin_array[:]
  • List comprehension [x**2 for x in range(1,7)] gives you [1,4,9,16,25,36] (Not readable)

Using list may also cause an aliasing bug (two distinct paths pointing to the same object).

First use this Namespace:

using System.Drawing;

Add this anywhere on your form:

listBox.DrawMode = DrawMode.OwnerDrawFixed;
listBox.DrawItem += listBox_DrawItem;

Here is the Event Handler:

private void listBox_DrawItem(object sender, DrawItemEventArgs e)
{
     e.DrawBackground();

     Graphics g = e.Graphics;
     g.FillRectangle(new SolidBrush(Color.White), e.Bounds);
     ListBox lb = (ListBox)sender;
     g.DrawString(lb.Items[e.Index].ToString(), e.Font, new SolidBrush(Color.Black), new PointF(e.Bounds.X, e.Bounds.Y));

     e.DrawFocusRectangle();
}

try

var lst= (from char c in source select c.ToString()).ToList();

There's a property that enables/disables in line media playback in the iOS web browser (if you were writing a native app, it would be the allowsInlineMediaPlayback property of a UIWebView). By default on iPhone this is set to NO, but on iPad it's set to YES.

Fortunately for you, you can also adjust this behaviour in HTML as follows:

<video id="myVideo" width="280" height="140" webkit-playsinline>

...that should hopefully sort it out for you. I don't know if it will work on your Android devices. It's a webkit property, so it might. Worth a go, anyway.

You have to store the timer id of the interval when you start it, you will use this value later to stop it, using the clearInterval function:

$(function () {
  var timerId = 0;

  $('textarea').focus(function () {
    timerId = setInterval(function () {
      // interval function body
    }, 1000);
  });

  $('textarea').blur(function () {
    clearInterval(timerId);
  });

});

The user-agents on iOS devices say iPhone or iPad in them. I just filter based on those keywords.

In Bootstrap, the .btn class has a white-space: nowrap; property, making it so that the button text won't wrap. So, after setting that to normal, and giving the button a width, the text should wrap to the next line if the text would exceed the set width.

#new-board-btn {
    white-space: normal;
}

http://jsfiddle.net/ADewB/

<form action="javascript:completeAndRedirect();">
    <input type="text" id="Edit1" 
    style="width:280; height:50; font-family:'Lucida Sans Unicode', 'Lucida Grande', sans-serif; font-size:22px">
</form>

Changing action to point at your function would solve the problem, in a different way.

Among all the valid points made on both sides I haven't found my main reason to avoid the wildcard: I like to be able to read the code and know directly what every class is, or if it's definition isn't in the language or the file, where to find it. If more than one package is imported with * I have to go search every one of them to find a class I don't recognize. Readability is supreme, and I agree code should not require an IDE for reading it.

Hibernate is ignorant of time zone stuff in Dates (because there isn't any), but it's actually the JDBC layer that's causing problems. ResultSet.getTimestamp and PreparedStatement.setTimestamp both say in their docs that they transform dates to/from the current JVM timezone by default when reading and writing from/to the database.

I came up with a solution to this in Hibernate 3.5 by subclassing org.hibernate.type.TimestampType that forces these JDBC methods to use UTC instead of the local time zone:

public class UtcTimestampType extends TimestampType {

    private static final long serialVersionUID = 8088663383676984635L;

    private static final TimeZone UTC = TimeZone.getTimeZone("UTC");

    @Override
    public Object get(ResultSet rs, String name) throws SQLException {
        return rs.getTimestamp(name, Calendar.getInstance(UTC));
    }

    @Override
    public void set(PreparedStatement st, Object value, int index) throws SQLException {
        Timestamp ts;
        if(value instanceof Timestamp) {
            ts = (Timestamp) value;
        } else {
            ts = new Timestamp(((java.util.Date) value).getTime());
        }
        st.setTimestamp(index, ts, Calendar.getInstance(UTC));
    }
}

The same thing should be done to fix TimeType and DateType if you use those types. The downside is you'll have to manually specify that these types are to be used instead of the defaults on every Date field in your POJOs (and also breaks pure JPA compatibility), unless someone knows of a more general override method.

UPDATE: Hibernate 3.6 has changed the types API. In 3.6, I wrote a class UtcTimestampTypeDescriptor to implement this.

public class UtcTimestampTypeDescriptor extends TimestampTypeDescriptor {
    public static final UtcTimestampTypeDescriptor INSTANCE = new UtcTimestampTypeDescriptor();

    private static final TimeZone UTC = TimeZone.getTimeZone("UTC");

    public <X> ValueBinder<X> getBinder(final JavaTypeDescriptor<X> javaTypeDescriptor) {
        return new BasicBinder<X>( javaTypeDescriptor, this ) {
            @Override
            protected void doBind(PreparedStatement st, X value, int index, WrapperOptions options) throws SQLException {
                st.setTimestamp( index, javaTypeDescriptor.unwrap( value, Timestamp.class, options ), Calendar.getInstance(UTC) );
            }
        };
    }

    public <X> ValueExtractor<X> getExtractor(final JavaTypeDescriptor<X> javaTypeDescriptor) {
        return new BasicExtractor<X>( javaTypeDescriptor, this ) {
            @Override
            protected X doExtract(ResultSet rs, String name, WrapperOptions options) throws SQLException {
                return javaTypeDescriptor.wrap( rs.getTimestamp( name, Calendar.getInstance(UTC) ), options );
            }
        };
    }
}

Now when the app starts, if you set TimestampTypeDescriptor.INSTANCE to an instance of UtcTimestampTypeDescriptor, all timestamps will be stored and treated as being in UTC without having to change the annotations on POJOs. [I haven't tested this yet]

Not least important is why these symbols occur in url. See https://www.php.net/manual/en/function.parse-str.php#76792, specifically:

parse_str('foo[]=1&foo[]=2&foo[]=3', $bar);

the above produces:

$bar = ['foo' => ['1', '2', '3'] ];

and what is THE method to separate query vars in arrays (in php, at least).

If you already know the process then this will be useful:

PID=`ps -eaf | grep <process> | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
echo "killing $PID"
kill -9 $PID
fi

Bonus Tip

You can't directly register an IUrlHelper in the DI container. Resolving an instance of IUrlHelper requires you to use the IUrlHelperFactory and IActionContextAccessor. However, you can do the following as a shortcut:

services
    .AddSingleton<IActionContextAccessor, ActionContextAccessor>()
    .AddScoped<IUrlHelper>(x => x
        .GetRequiredService<IUrlHelperFactory>()
        .GetUrlHelper(x.GetRequiredService<IActionContextAccessor>().ActionContext));

ASP.NET Core Backlog

UPDATE: This won't make ASP.NET Core 5

There are indications that you will be able to use LinkGenerator to create absolute URL's without the need to provide a HttpContext (This was the biggest downside of LinkGenerator and why IUrlHelper although more complex to setup using the solution below was easier to use) See "Make it easy to configure a host/scheme for absolute URLs with LinkGenerator".

You can do this in jquery by setting the attribute disabled to 'disabled'.

$(this).prop('disabled', true);

I was not sure about the tests in OP. I decided to experiment a little and ended up busting some of the myths.

Synchronous <script src...> will block downloading of the resources below it until it is downloaded and executed

This is no longer true. Have a look at the waterfall generated by Chrome 63:

<head>
<script src="//alias-0.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=1"></script>
<script src="//alias-1.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=2"></script>
<script src="//alias-2.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=3"></script>
</head>

<link rel=stylesheet> will not block download and execution of scripts below it

This is incorrect. The stylesheet will not block download but it will block execution of the script (little explanation here). Have a look at performance chart generated by Chrome 63:

<link href="//alias-0.redacted.com/payload.php?type=css&amp;delay=666" rel="stylesheet">
<script src="//alias-1.redacted.com/payload.php?type=js&amp;delay=333&amp;block=1000"></script>

Keeping the above in mind, the results in OP can be explained as follows:

Me Too

How about using some beautiful markup with Kotlin and Anko -

import org.jetbrains.anko.*
override fun onCreate(savedInstanceState: Bundle?) {
    title = "Created with Beautiful Markup"
    super.onCreate(savedInstanceState)

    verticalLayout {
        editText {
            hint = buildSpanned {
                append("Italic, ", Italic)
                append("highlighted", backgroundColor(0xFFFFFF00.toInt()))
                append(", Bold", Bold)
            }
        }
    }
}

The famous Moodle "replace.php" script can generate this situation too. For me it was taking ages to run and then failed with a 500 message in the browser and also with the above error message in my apache error log file.

I followed up on @james-wise answer: FcgidBusy is readably described in the Apache documentation. I tried this: doubled the amount of time which apache would give my script to run, by inserting the following line in /etc/apache2/mods-available/fcgid.conf

FcgidBusyTimeout 600

Then I restarted Apache and tried to run my replace.php script again.

Fortunately this time the script instance ran to completion, so for my purposes this served as a solution.

You are trying to index into a scalar (non-iterable) value:

[y[1] for y in y_test]
#  ^ this is the problem

When you call [y for y in test] you are iterating over the values already, so you get a single value in y.

Your code is the same as trying to do the following:

y_test = [1, 2, 3]
y = y_test[0] # y = 1
print(y[0]) # this line will fail

I'm not sure what you're trying to get into your results array, but you need to get rid of [y[1] for y in y_test].

If you want to append each y in y_test to results, you'll need to expand your list comprehension out further to something like this:

[results.append(..., y) for y in y_test]

Or just use a for loop:

for y in y_test:
    results.append(..., y)

I have the same problem with a class. I tried composer dump-autoload and php artisan config:clear but it did not solve my problem.

Then I decided to read my code to find the problem and I found the problem. The problem in my case was a missing comma in my class. See my Model code:

{
    protected
    $fillable = ['agente_id', 'matter_id', 'amendment_id', 'tipo_id'];

    public
    $rules = [
        'agente_id' => 'required', // <= See the comma
        'tipo_id' => 'required'
    ];

    public
    $niceNames = [
        'agente_id' => 'Membro', // <= This comma is missing on my code
        'tipo_id' => 'Membro'
    ];
}

Ok I think I have solves the problem below is a working code

//
package xmlhttp;

import org.jdesktop.http.Response;

import org.jdesktop.http.Session;

import org.jdesktop.http.State;



public class GetXmlHttp{


    public static void main(String[] args) {

        getResponse();

    }

    public static void getResponse()
    {

        final Session session = new Session();

        try {
            String url="http://192.172.2.23:8080/geoserver/wfs?request=GetFeature&version=1.1.0&outputFormat=GML2&typeName=topp:networkcoverage,topp:tehsil&bbox=73.07846689124875,33.67929015631999,73.07946689124876,33.68029015632,EPSG:4326";
            final Response res=session.get(url);
            boolean notDone=true;
            do
            {
                System.out.print(session.getState().toString());

                if(session.getState()==State.DONE)
                {
                    String xml=res.toString();
                    System.out.println(xml);
                    notDone=false;


                }

            }while(notDone);

        } catch (Exception e1) {

            e1.printStackTrace();
        }


    }

}
