@Adam Just add a function using onClick="getId()"

function getId(){console.log(this.event.target.id)}

Pandas is based on NumPy arrays. The key to speed with NumPy arrays is to perform your operations on the whole array at once, never row-by-row or item-by-item.

For example, if close is a 1-d array, and you want the day-over-day percent change,

pct_change = close[1:]/close[:-1]

This computes the entire array of percent changes as one statement, instead of

pct_change = []
for row in close:
    pct_change.append(...)

So try to avoid the Python loop for i, row in enumerate(...) entirely, and think about how to perform your calculations with operations on the entire array (or dataframe) as a whole, rather than row-by-row.

I think the simplest way is to turn each array into a string like you tried, and compare the strings.

To convert the arrays into string, just put this string of methods onto the arrays. These are the arrays:

var arr1 = [1, 2, "foo", 3, "bar", 3.14]
var arr2 = [1, 2, "foo", 3, "bar", 3.14]

Now, you have to convert them into the strings. The list of methods are:

arr1.toString().replace(/,/gi, "")
arr2.toString().replace(/,/gi, "")

The methods do:

**.toString()** -

Turns array into a string, concatenating the elements of the array.

Ex. ["tree", "black hole"] -> "tree,black hole"

Sadly, it includes the commas. That is why we have to do:

***.replace(a, b)***

It finds and replaces the first argument (a) with the second argument (b) in the string you are doing it on.

Ex.

"0000010000010000000".replace("1", "2")

will return: "0000020000010000000"

It only replaces the first instance of parameter 1, so we can do regex instead.

Ex.

"0000010000010000000".replace(/1/gi, "2")

will return: "0000020000020000000"

You wrap what you want to replace with /. Say what you want to replace is 1. You make it: /1/. But then you have to add the gi at the end so that it selects every instance. So, you have to put /1/gi with a comma at the end, and then you can put what you want to replace it with.

Now, your two arrays are:

arr1: "12foo3bar3.14" arr2: "12foo3bar3.14"

Now you say this:

if(arr1 === arr2) {
  // Now the code you put inside of this if statement will only run if arr1 and arr2 have the same contents.
} else {
  // This code will run if arr1 and arr2 have any differences.
}

If you want to check if arr1 CONTAINS arr2 instead of having the same exact contents, you do this.

if(arr1.indexOf(arr2) !== -1) {
    //This code will happen if arr2 is inside of arr1. If there is one extra array 
    //item in arr1, it doesn't matter. But, if arr2 has an extra array item, nothing in 
    //this if will run. If you want arr2 to contain arr1, just make arr1 in the 
    //condition of this if arr2, and make arr2 arr1.
}

Basically, if you want the arrays to be the EXACT SAME, do this:

if(arr1.toString().replace(/,/gi, "") === arr2.toString().replace(/,/gi, "")) {
    //arrays are the same
} else {
    //arrays are different
}

And if you want to know if an array contains another, just do this:

arrayThatWillHoldAnotherArray = arrayThatWillHoldAnotherArray.toString().replace(/,/gi)
arrayThatWillBeInsideAnotherArray = arrayThatWillBeInsideAnotherArray.toString().replace(/,/gi)


if(arrayThatWillHoldAnotherArray.indexOf(arrayThatWillBeInsideAnotherArray) !== -1) {
    //arrayThatWillHoldAnotherArray has arrayThatWillBeInsideAnotherArray inside of it
} else {
    //it doesn't
}

console.log("Read the code to understand this.")
var arr1 = [1,2,"foo",3,"bar",3.14]
var arr2 = [1,2,"foo",3,"bar",3.14]
function checkIfArraysAreTheSame(a,b) {
  if(a.toString().replace(/,/gi,"") === b.toString().replace(/,/gi,"")) {
    console.log("A and B are the same!")
    return true;
  }
  console.log("A and B are NOT the same!")
  return false
}
checkIfArraysAreTheSame(arr1,arr2)
//expected output: A and B are the same!
//Now, let's add another item to arr2.
arr2.push("Lorem")
checkIfArraysAreTheSame(arr1,arr2)
//expected output: A and B are NOT the same!

function checkIfArrayIsNestedInsideAnother(a,b) {
  //If this returns true, b is nested inside a.
  if (a.toString().replace(/,/gi,"").indexOf(b.toString().replace(/,/gi,"")) > -1) {
    console.log("B is nested inside of A!")
  } else if(b.toString().replace(/,/gi,"").indexOf(a.toString().replace(/,/gi,"")) > -1) {
    console.log("A is nested inside of B!")
  }
}

checkIfArrayIsNestedInsideAnother(arr1, arr2)
//expected output: A is nested inside of B! because:
//arr1 (a): [1,2,"foo",3,"bar",3.14]
//arr2 (b): [1,2,"foo",3,"bar",3.14, "Lorem"]
//We added Lorem at line 15.

//Now, let's check if arr2 is nested inside arr1, which it is not.
checkIfArrayIsNestedInsideAnother(arr2, arr1)
//expected output: B is nested inside of A!

This also happens if you're missing an empty public constructor for the Entity (could be for JSON, XML etc)..

PowerShell features a Restart-Service cmdlet, which either starts or restarts the service as appropriate.

The Restart-Service cmdlet sends a stop message and then a start message to the Windows Service Controller for a specified service. If a service was already stopped, it is started without notifying you of an error.

You can specify the services by their service names or display names, or you can use the InputObject parameter to pass an object that represents each service that you want to restart.

It is a little more foolproof than running two separate commands.

The easiest way to use it just pass either the service name or the display name directly:

Restart-Service 'Service Name'

It can be used directly from the standard cmd prompt with a command like:

powershell -command "Restart-Service 'Service Name'"

You can use sqlite3 and pep-249

import sqlite3
connection = sqlite3.connect('~/foo.sqlite')
cursor = connection.execute('select * from bar')

cursor.description is description of columns

names = list(map(lambda x: x[0], cursor.description))

Alternatively you could use a list comprehension:

names = [description[0] for description in cursor.description]

This can be easily done by using rd command with two parameters:

rd <folder> /Q /S

• /Q - Quiet mode, do not ask if ok to remove a directory tree with /S

• /S - Removes all directories and files in the specified directory in addition to the directory itself. Used to remove a directory tree.

There should also be a YEAR().

As for comparing, you could compare dates that are the first days of those years and months, or you could convert the year/month pair into a number suitable for comparison (i.e. bigger = later). (Exercise left to the reader. For hints, read about the ISO date format.)

Or you could use multiple comparisons (i.e. years first, then months).

You most likely want to examine the documentation for T-SQL's CAST and CONVERT functions, located in the documentation here: http://msdn.microsoft.com/en-US/library/ms187928(v=SQL.90).aspx

You will then use one of those functions in your T-SQL query to convert the [idate] column from the database into the datetime format of your liking in the output.

int days = (int) (milliseconds / 86 400 000 )

Well, timing to the rescue again. It seems switch is generally faster than if statements. So that, and the fact that the code is shorter/neater with a switch statement leans in favor of switch:

# Simplified to only measure the overhead of switch vs if

test1 <- function(type) {
 switch(type,
        mean = 1,
        median = 2,
        trimmed = 3)
}

test2 <- function(type) {
 if (type == "mean") 1
 else if (type == "median") 2
 else if (type == "trimmed") 3
}

system.time( for(i in 1:1e6) test1('mean') ) # 0.89 secs
system.time( for(i in 1:1e6) test2('mean') ) # 1.13 secs
system.time( for(i in 1:1e6) test1('trimmed') ) # 0.89 secs
system.time( for(i in 1:1e6) test2('trimmed') ) # 2.28 secs

Update With Joshua's comment in mind, I tried other ways to benchmark. The microbenchmark seems the best. ...and it shows similar timings:

> library(microbenchmark)
> microbenchmark(test1('mean'), test2('mean'), times=1e6)
Unit: nanoseconds
           expr  min   lq median   uq      max
1 test1("mean")  709  771    864  951 16122411
2 test2("mean") 1007 1073   1147 1223  8012202

> microbenchmark(test1('trimmed'), test2('trimmed'), times=1e6)
Unit: nanoseconds
              expr  min   lq median   uq      max
1 test1("trimmed")  733  792    843  944 60440833
2 test2("trimmed") 2022 2133   2203 2309 60814430

Final Update Here's showing how versatile switch is:

switch(type, case1=1, case2=, case3=2.5, 99)

This maps case2 and case3 to 2.5 and the (unnamed) default to 99. For more information, try ?switch

Well, why this exists in general is probably different than why it exists in your example.

It all started half a century ago with repurposing hardcopy communication terminals as computer user interfaces. In the initial Unix and C era that was the ASR-33 Teletype.

This device was slow (10 cps) and noisy and ugly and its view of the ASCII character set ended at 0x5f, so it had (look closely at the pic) none of the keys:

{ | } ~ 

The trigraphs were defined to fix a specific problem. The idea was that C programs could use the ASCII subset found on the ASR-33 and in other environments missing the high ASCII values.

Your example is actually two of ??!, each meaning |, so the result is ||.

However, people writing C code almost by definition had modern equipment,¹ so my guess is: someone showing off or amusing themself, leaving a kind of Easter egg in the code for you to find.

It sure worked, it led to a wildly popular SO question.

• A worker process runs as an executables file named W3wp.exe

• A Worker Process is user mode code whose role is to process requests, such as processing requests to return a static page.

• The worker process is controlled by the www service.

• worker processes also run application code, Such as ASP .NET applications and XML web Services.

• When Application pool receive the request, it simply pass the request to worker process (w3wp.exe) . The worker process“w3wp.exe” looks up the URL of the request in order to load the correct ISAPI extension. ISAPI extensions are the IIS way to handle requests for different resources. Once ASP.NET is installed, it installs its own ISAPI extension (aspnet_isapi.dll)and adds the mapping into IIS.

• When Worker process loads the aspnet_isapi.dll, it start an HTTPRuntime, which is the entry point of an application. HTTPRuntime is a class which calls the ProcessRequest method to start Processing.

The following works for me when disabling Findbugs in a child POM:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>findbugs-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>ID_AS_IN_PARENT</id> <!-- id is necessary sometimes -->
            <phase>none</phase>
        </execution>
    </executions>
</plugin>

Note: the full definition of the Findbugs plugin is in our parent/super POM, so it'll inherit the version and so-on.

In Maven 3, you'll need to use:

 <configuration>
      <skip>true</skip>
 </configuration>

for the plugin.

Imho the best solution is:

fooBar | 0

This is used in asm.js to force integer type.

 DATE_ADD(FROM_DATE_HERE, INTERVAL INTERVAL_TIME_HERE DAY) 

will give the Date after adjusting the INTERVAL

eg.

DATE_ADD(NOW(), INTERVAL -1 DAY) for deducting 1 DAY from current Day
DATE_ADD(NOW(), INTERVAL 2 DAY)  for adding 2 Days

You can use like

UPDATE classes WHERE date=(DATE_ADD(date, INTERVAL 1 DAY)) WHERE id=161

Here is what official SQLite documentation has to say on the subject (bold & italic are mine):

1. The AUTOINCREMENT keyword imposes extra CPU, memory, disk space, and disk I/O overhead and should be avoided if not strictly needed. It is usually not needed.

2. In SQLite, a column with type INTEGER PRIMARY KEY is an alias for the ROWID (except in WITHOUT ROWID tables) which is always a 64-bit signed integer.

3. On an INSERT, if the ROWID or INTEGER PRIMARY KEY column is not explicitly given a value, then it will be filled automatically with an unused integer, usually one more than the largest ROWID currently in use. This is true regardless of whether or not the AUTOINCREMENT keyword is used.

4. If the AUTOINCREMENT keyword appears after INTEGER PRIMARY KEY, that changes the automatic ROWID assignment algorithm to prevent the reuse of ROWIDs over the lifetime of the database. In other words, the purpose of AUTOINCREMENT is to prevent the reuse of ROWIDs from previously deleted rows.

One place where it's useful is for UI activities, like setting a spinner before a lengthy operation:

- (void) handleDoSomethingButton{

    [mySpinner startAnimating];

    (do something lengthy)
    [mySpinner stopAnimating];
}

will not work, because you are blocking the main thread during your lengthy thing and not letting UIKit actually start the spinner.

- (void) handleDoSomethingButton{
     [mySpinner startAnimating];

     dispatch_async (dispatch_get_main_queue(), ^{
          (do something lengthy)
          [mySpinner stopAnimating];
    });
}

will return control to the run loop, which will schedule UI updating, starting the spinner, then will get the next thing off the dispatch queue, which is your actual processing. When your processing is done, the animation stop is called, and you return to the run loop, where the UI then gets updated with the stop.

I assume you install gems into vendor/bundle? If so, why not just delete all the gems and do a clean bundle install?

I've just replied to the related question given by Vanuan (Eclipse CDT: Unresolved inclusion of stl header), and this is my answer :

You could also try use "CDT GCC Built-in Compiler Settings". Go to the project properties > C/C++ General > Preprocessor Include Path > Providers tab then check "CDT GCC Built-in Compiler Settings" if it is not.

None of the other solutions (play with include path, etc) worked for me for the type 'string', but this one fixed it.

jQuery is simply supporting the way CSS is written.

Also, it ensures that no matter how a browser returns a value, it will be understood

jQuery can equally interpret the CSS and DOM formatting of multiple-word properties. For example, jQuery understands and returns the correct value for both .css('background-color') and .css('backgroundColor').

It means the CPU attempted to execute an instruction it didn't understand. This could be caused by corruption I guess, or maybe it's been compiled for the wrong architecture (in which case I would have thought the O/S would refuse to run the executable). Not entirely sure what the root issue is.

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

Try this:

your_command 2>stderr.log 1>stdout.log

The numerals 0 through 9 are file descriptors in bash. 0 stands for standard input, 1 stands for standard output, 2 stands for standard error. 3 through 9 are spare for any other temporary usage.

Any file descriptor can be redirected to a file or to another file descriptor using the operator >. You can instead use the operator >> to appends to a file instead of creating an empty one.

Usage:

file_descriptor > filename

file_descriptor > &file_descriptor

Strings in c# are immutable. When in your code you do strgroupids.TrimEnd(','); or strgroupids.TrimEnd(new char[] { ',' }); the strgroupids string is not modified.

You need to do something like strgroupids = strgroupids.TrimEnd(','); instead.

To quote from here:

Strings are immutable--the contents of a string object cannot be changed after the object is created, although the syntax makes it appear as if you can do this. For example, when you write this code, the compiler actually creates a new string object to hold the new sequence of characters, and that new object is assigned to b. The string "h" is then eligible for garbage collection.

Here's the answer to all your questions: http://wiki.python.org/moin/PythonEditors

Simple to Spit String by Space

    String CurrentString = "First Second Last";
    String[] separated = CurrentString.split(" ");

    for (int i = 0; i < separated.length; i++) {

         if (i == 0) {
             Log.d("FName ** ", "" + separated[0].trim() + "\n ");
         } else if (i == 1) {
             Log.d("MName ** ", "" + separated[1].trim() + "\n ");
         } else if (i == 2) {
             Log.d("LName ** ", "" + separated[2].trim());
         }
     }

Consistency is the key to any naming standard. As long as it's logical and consistent, you're 99% there.

The standard itself is very much personal preference - so if you like your standard, then run with it.

To answer your question outright - no, MySQL doesn't have a preferred naming convention/standard, so rolling your own is fine (and yours seems logical).

The pixels array is stored in the "data" attribute of cv::Mat. Let's suppose that we have a Mat matrix where each pixel has 3 bytes (CV_8UC3).

For this example, let's draw a RED pixel at position 100x50.

Mat foo;
int x=100, y=50;

Solution 1:

Create a macro function that obtains the pixel from the array.

#define PIXEL(frame, W, x, y) (frame+(y)*3*(W)+(x)*3)
//...
unsigned char * p = PIXEL(foo.data, foo.rols, x, y);
p[0] = 0;   // B
p[1] = 0;   // G
p[2] = 255; // R

Solution 2:

Get's the pixel using the method ptr.

unsigned char * p = foo.ptr(y, x); // Y first, X after
p[0] = 0;   // B
p[1] = 0;   // G
p[2] = 255; // R

You seem to be using grep() like the Unix grep utility, which is wrong.

Perl's grep() in scalar context evaluates the expression for each element of a list and returns the number of times the expression was true. So when $match contains any "true" value, grep($match, @array) in scalar context will always return the number of elements in @array.

Instead, try using the pattern matching operator:

if (grep /$match/, @array) {
    print "found it\n";
}

you can use:

Stopwatch.GetTimestamp();

Short, portable and declared in stdio.h

stdin = freopen(NULL,"r",stdin);

Doesn't get hung in an infinite loop when there is nothing on stdin to flush like the following well know line:

while ((c = getchar()) != '\n' && c != EOF) { }

A little expensive so don't use it in a program that needs to repeatedly clear the buffer.

Stole from a coworker :)

Try using another temporary pair:

pair<string,double> temp;
vector<pair<string,double>> revenue;

// Inside the loop
temp.first = "string";
temp.second = map[i].second;
revenue.push_back(temp);

Building on the solution provided I thought it might be helpful to show an example passing your own custom data object (which I've referenced here as 'message' as per question).

Class A (sender):

YourDataObject *message = [[YourDataObject alloc] init];
// set your message properties
NSDictionary *dict = [NSDictionary dictionaryWithObject:message forKey:@"message"];
[[NSNotificationCenter defaultCenter] postNotificationName:@"NotificationMessageEvent" object:nil userInfo:dict];

Class B (receiver):

- (void)viewDidLoad

If you want to ignore lines with only whitespace:

if not line.strip():
    ... do something

The empty string is a False value.

Or if you really want only empty lines:

if line in ['\n', '\r\n']:
    ... do  something

This worked for me with inline text. It was tested in Firefox, Safari, Chrome, and Opera.

<p>Lorem ipsum dolor sit amet, consectetur <span>Some Text</span> adipiscing elit.</p>

span {
    visibility: hidden;
    word-spacing: -999px;
    letter-spacing: -999px;
}

span:after {
    content: "goodbye";
    visibility: visible;
    word-spacing: normal;
    letter-spacing: normal;
}

I believe VS2010 to be right this time, and I'd check if I had the standard handy, but currently I don't.

Now, it's exactly like the error message says: You can't capture stuff outside of the enclosing scope of the lambda.^† grid is not in the enclosing scope, but this is (every access to grid actually happens as this->grid in member functions). For your usecase, capturing this works, since you'll use it right away and you don't want to copy the grid

auto lambda = [this](){ std::cout << grid[0][0] << "\n"; }

If however, you want to store the grid and copy it for later access, where your puzzle object might already be destroyed, you'll need to make an intermediate, local copy:

vector<vector<int> > tmp(grid);
auto lambda = [tmp](){}; // capture the local copy per copy

† I'm simplifying - Google for "reaching scope" or see §5.1.2 for all the gory details.

Newtonsoft.JSON is a good solution for these kind of situations. Also Newtonsof.JSON is faster than others, such as JavaScriptSerializer, DataContractJsonSerializer.

In this sample, you can the following:

var jsonData = JObject.Parse("your JSON data here");

Then you can cast jsonData to JArray, and you can use a for loop to get data at each iteration.

Also, I want to add something:

for (int i = 0; (JArray)jsonData["data"].Count; i++)
{
    var data = jsonData[i - 1];
}

Working with dynamic object and using Newtonsoft serialize is a good choice.

A tricky way:

If you develop under Lunux, you can use all the power of sed:

from subprocess import check_call, CalledProcessError

PATH_TO_FILE = '/home/user/some/path/to/file.csv'

try:
    check_call("sed -i -e 's|\\x0||g' {}".format(PATH_TO_FILE), shell=True)
except CalledProcessError as err:
    print(err)    

The most efficient solution for huge files.

Checked for Python3, Kubuntu

Check out the split function of String Here, and use it something like this String[] results = input.split("\\s+");. The regular expresion bit spilts on whitespaces, it should do the trick

The best solution is toString (as stated above):

function getRealObjectType(obj: {}): string {
    return Object.prototype.toString.call(obj).match(/\[\w+ (\w+)\]/)[1].toLowerCase();
}

FAIR WARNING: toString considers NaN a number so you must manually safeguard later with Number.isNaN(value).

The other solution suggested, using Object.getPrototypeOf fails with null and undefined

I found that when I made my binding more specific, it began to work on iOS. I had:

$(document).on('click tap', 'span.clickable', function(e){ ... });

When I changed it to:

$("div.content").on('click tap', 'span.clickable', function(e){ ... });

iOS began responding.

Here is another method: using SQL Server Management Studio, in Object Explorer, go to your database and select Tables

Then open the Object Explorer Details (either by pressing F7 or going to View->Object Explorer Details). In the object explorer details page, right click on the column header and enable the columns that you would like to see in the page. You can sort the data by any column too.

Tag helpers:

<a asp-controller="OtherController" asp-action="Index" class="btn btn-primary"> Back to Other Controller View </a>

In the controller.cs have a method:

public async Task<IActionResult> Index()
{
    ViewBag.Title = "Titles";
    return View(await Your_Model or Service method);
}

Try this:

SELECT user.userID, edge.TailUser, edge.Weight 
FROM user
LEFT JOIN edge ON edge.HeadUser = User.UserID
WHERE edge.HeadUser=5043

OR

AND edge.HeadUser=5043

instead of WHERE clausule.

You might want to check HTML frames, which can do pretty much exactly what you are looking for. They are considered outdated however.

You can use the list length. The last index will be the length of the list minus one.

len(list1)-1 == 3

I created this test case: http://jsfiddle.net/ccQnK/1/ , I used the Javascript replace function with regular expressions to get the results that you want.

$(document).ready(function() {
    var myContent = '<div id="test">Hello <span>world!</span></div>';
    alert(myContent.replace(/(<([^>]+)>)/ig,""));
});

There is a big difference. Tasks are scheduled on the ThreadPool and could even be executed synchronous if appropiate.

If you have a long running background work you should specify this by using the correct Task Option.

You should prefer Task Parallel Library over explicit thread handling, as it is more optimized. Also you have more features like Continuation.

assuming certain column names...

INSERT one

newToner = Toner(toner_id = 1,
                    toner_color = 'blue',
                    toner_hex = '#0F85FF')

dbsession.add(newToner)   
dbsession.commit()

INSERT multiple

newToner1 = Toner(toner_id = 1,
                    toner_color = 'blue',
                    toner_hex = '#0F85FF')

newToner2 = Toner(toner_id = 2,
                    toner_color = 'red',
                    toner_hex = '#F01731')

dbsession.add_all([newToner1, newToner2])   
dbsession.commit()

UPDATE

q = dbsession.query(Toner)
q = q.filter(Toner.toner_id==1)
record = q.one()
record.toner_color = 'Azure Radiance'

dbsession.commit()

or using a fancy one-liner using MERGE

record = dbsession.merge(Toner( **kwargs))

Not spectacular different than the answers already given, but more generic is :

sortArrayOfObjects = (arr, key) => {
    return arr.sort((a, b) => {
        return a[key] - b[key];
    });
};

sortArrayOfObjects(yourArray, "distance");

I consider a modern IDE to be critical for understanding large scala projects. Since these operators are also methods, in intellij idea I just control-click or control-b into the definitions.

You can control-click right into a cons operator (::) and end up at the scala javadoc saying "Adds an element at the beginning of this list." In user-defined operators, this becomes even more critical, since they could be defined in hard-to-find implicits... your IDE knows where the implicit was defined.

step 1:

Download dex2jar here. Create a java project and paste (dex2jar-0.0.7.11-SNAPSHOT/lib ) jar files .

Copy apk file into java project

Run it and after refresh the project ,you get jar file .Using java decompiler you can view all java class files

step 2: Download java decompiler here

SQL Developer seems to only output the DBMS_OUTPUT text when you have explicitly turned on the DBMS_OUTPUT window pane.

Go to (Menu) VIEW -> Dbms_output to invoke the pane.

Click on the Green Plus sign to enable output for your connection and then run the code.

EDIT: Don't forget to set the buffer size according to the amount of output you are expecting.

Have seen so many that don't really work. when a temp table is created it must be deleted from the tempdb!

The only code that works is:

IF OBJECT_ID('tempdb..#tempdbname') IS NOT NULL     --Remove dbo here 
    DROP TABLE #tempdbname   -- Remoeve "tempdb.dbo"

If you have table and storing the ID as primary and auto increment then this will work

You are giving the span a 100% width resulting in it expanding to the size of the parent. This means you can’t center-align it, as there is no room to move it.

You could give the span a set width, then add the margin:0 auto again. This would center-align it.

.left 
{
   background-color: #999999;
   height: 50px;
   width: 24.5%;
}
span.panelTitleTxt 
{
   display:block;
   width:100px;
   height: 100%;
   margin: 0 auto;
}

The event attribute of <f:ajax> can hold at least all supported DOM events of the HTML element which is been generated by the JSF component in question. An easy way to find them all out is to check all on* attribues of the JSF input component of interest in the JSF tag library documentation and then remove the "on" prefix. For example, the <h:inputText> component which renders <input type="text"> lists the following on* attributes (of which I've already removed the "on" prefix so that it ultimately becomes the DOM event type name):

• blur
• change
• click
• dblclick
• focus
• keydown
• keypress
• keyup
• mousedown
• mousemove
• mouseout
• mouseover
• mouseup
• select

Additionally, JSF has two more special event names for EditableValueHolder and ActionSource components, the real HTML DOM event being rendered depends on the component type:

• valueChange (will render as change on text/select inputs and as click on radio/checkbox inputs)
• action (will render as click on command links/buttons)

The above two are the default events for the components in question.

Some JSF component libraries have additional customized event names which are generally more specialized kinds of valueChange or action events, such as PrimeFaces <p:ajax> which supports among others tabChange, itemSelect, itemUnselect, dateSelect, page, sort, filter, close, etc depending on the parent <p:xxx> component. You can find them all in the "Ajax Behavior Events" subsection of each component's chapter in PrimeFaces Users Guide.

I had the same problem. I called a method inside viewDidLoad inside my first UIViewController

- (void)viewDidLoad{
    [super viewDidLoad];

    [self performSelector:@selector(loadingView)
               withObject:nil afterDelay:0.5];
}

- (void)loadingView{

    [self performSegueWithIdentifier:@"loadedData" sender:self];
}

Inside the second UIViewController I did the same also with 0.5 seconds delay. After changing the delay to a higher value, it worked fine. It's like the segue can't be performed too fast after another segue.

It turns out there is more complexity here: I needed to provide many more details to get this rolling. I think its something to do with the fact that its a connection that needs client authentication, and the hankshake needed more info to continue to the stage where the certificates were dumped.

Here is my working command:

openssl s_client -connect host:port -key our_private_key.pem -showcerts \
                 -cert our_server-signed_cert.pem

Hopefully this is a nudge in the right direction for anyone who could do with some more info.

I don't have enough rep to put this under comments to the existing answers:

unescape is only deprecated for working with URIs (or any encoded utf-8) which is probably the case for most people's needs. encodeURIComponent converts a js string to escaped UTF-8 and decodeURIComponent only works on escaped UTF-8 bytes. It throws an error for something like decodeURIComponent('%a9'); // error because extended ascii isn't valid utf-8 (even though that's still a unicode value), whereas unescape('%a9'); // © So you need to know your data when using decodeURIComponent.

decodeURIComponent won't work on "%C2" or any lone byte over 0x7f because in utf-8 that indicates part of a surrogate. However decodeURIComponent("%C2%A9") //gives you © Unescape wouldn't work properly on that // © AND it wouldn't throw an error, so unescape can lead to buggy code if you don't know your data.

JavaScript doesn't have a built-in init() function, that is, it's not a part of the language. But it's not uncommon (in a lot of languages) for individual programmers to create their own init() function for initialisation stuff.

A particular init() function may be used to initialise the whole webpage, in which case it would probably be called from document.ready or onload processing, or it may be to initialise a particular type of object, or...well, you name it.

What any given init() does specifically is really up to whatever the person who wrote it needed it to do. Some types of code don't need any initialisation.

function init() {
  // initialisation stuff here
}

// elsewhere in code
init();

The computer "name" is resolved from the IP address by the underlying DNS (Domain Name System) library of the OS. There's no universal concept of a computer name across OSes, but DNS is generally available. If the computer name hasn't been configured so DNS can resolve it, it isn't available.

import java.net.InetAddress;
import java.net.UnknownHostException;

String hostname = "Unknown";

try
{
    InetAddress addr;
    addr = InetAddress.getLocalHost();
    hostname = addr.getHostName();
}
catch (UnknownHostException ex)
{
    System.out.println("Hostname can not be resolved");
}

Jar class/package is for specific Jar file mechanisms where there is a manifest that is used by the Jar files in some cases.

The Zip file class/package handles any compressed files that include Jar files, which is a type of compressed file.

The Jar classes thus extend the Zip package classes.

Today i have this issue because i have implemented "bootstrap menu" that uses a jQuery version along with "fancybox image gallery". Of course one plugin works and the other not due to jQuery conflict but i have overcome it as follow:

First i have added the "bootstrap menu" Js in the script footer as the menu is presented allover the website pages:

<!-- Top Menu Javascript -->
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>
<script type="text/javascript">
var jq171 = jQuery.noConflict(true);
</script>

And in the "fancybox" image gallery page as follow:

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
    <script>window.jQuery || document.write('<script src="fancybox/js/libs/jquery-1.7.1.min.js"><\/script>')</script>

And the good thing is both working like a charm :)

Give it a try :)

Use JQuery, its easy.

Include the JQuery library into your html file in the head as such:

<head>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>

(Make sure that this script tag goes before your other script tags in your html file)

Target your id in your JavaScript file as such:

<script>
var youtubeimcsrc = $('#youtubeimg').attr('src');

//your var will be the src string that you're looking for

</script>

String start_dt = "2011-01-31";

DateFormat parser = new SimpleDateFormat("yyyy-MM-dd"); 
Date date = (Date) parser.parse(start_dt);

DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy"); 
System.out.println(formatter.format(date));

Prints: 01-31-2011

This is what matplotlib.pyplot.scatter is for.

As a quick example:

import matplotlib.pyplot as plt
import numpy as np

# Generate data...
t = np.linspace(0, 2 * np.pi, 20)
x = np.sin(t)
y = np.cos(t)

plt.scatter(t,x,c=y)
plt.show()

" 1- Go to the web.config of your application "

" 2- Add a new entry under < system.web > "

3- Also Find the pages tag and set validateRequest=False

Only this works for me. !!

Instruction from AWS EC2 support:

1. Change pem login
2. go to your EC2 Console
3. Under NETWORK & SECURITY, click on Key Pair Click on Create Key Pair
4. Give your new key pair a name, save the .pem file. The name of the key pair will be used to connect to your instance
5. Create SSH connection to your instance and keep it open
6. in PuttyGen, click "Load" to load your .pem file
7. Keep the SSH-2 RSA radio button checked. Click on "Save private key" You'll get pop-up window warning, click "Yes”
8. click on "Save public key" as well, so to generate the public key. This is the public key that we're going to copy across to your current instance
9. Save the public key with the new key pair name and with the extension .pub
10. Open the public key content in a notepad
11. copy the content below "Comment: "imported-openssh-key" and before "---- END SSH2 PUBLIC KEY ----
    Note - you need to copy the content as one line - delete all new lines
12. on your connected instance, open your authorized_keys file using the tool vi. Run the following command: vi .ssh/authorized_keys you should see the original public key in the file also
13. move your cursor on the file to the end of your first public key content :type "i" for insert
14. on the new line, type "ssh-rsa" and add a space before you paste the content of the public key , space, and the name of the .pem file (without the .pem) Note - you should get a line with the same format as the previous line
15. press the Esc key, and then type :wq!

this will save the updated authorized_keys file

now try open a new SSH session to your instance using your new key pai

When you've confirmed you're able to SSH into the instance using the new key pair, u can vi .ssh/authorized_key and delete the old key.

Answer to Shaggie remark:

If you are unable to connect to the instance (e.g. key is corrupted) than use the AWS console to detach the volume (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-detaching-volume.html) and reattach it to working instance, than change the key on the volume and reattach it back to the previous instance.

use this Reload page

success: function(data){
   if(data.success == true){ // if true (1)
      setTimeout(function(){// wait for 5 secs(2)
           location.reload(); // then reload the page.(3)
      }, 5000); 
   }
}

http://api.jquery.com/jQuery.inArray/

if ($.inArray('example', myArray) != -1)
{
  // found it
}

one of the easy way to do that is use landa function without any problem like

userControl_Material1.simpleButton4.Click += (s, ee) =>
            {
                Save_mat(mat_global);
            };

For this to make sense, you have to understand the basics of paging: How does x86 paging work? and in particular that the OS can allocate virtual memory via page tables / its internal memory book keeping (VSZ virtual memory) before it actually has a backing storage on RAM or disk (RSS resident memory).

Now to observe this in action, let's create a program that:

• allocates more RAM than our physical memory with mmap
• writes one byte on each page to ensure that each of those pages goes from virtual only memory (VSZ) to actually used memory (RSS)
• checks the memory usage of the process with one of the methods mentioned at: Memory usage of current process in C

Killed

Exit status:

137

which by the 128 + signal number rule means we got signal number 9, which man 7 signal says is SIGKILL, which is sent by the Linux out-of-memory killer.

Output interpretation:

• VSZ virtual memory remains constant at printf '0x%X\n' 0x40009A4 KiB ~= 64GiB (ps values are in KiB) after the mmap.
• RSS "real memory usage" increases lazily only as we touch the pages. For example:
  • on the first print, we have extra_memory_committed 0, which means we haven't yet touched any pages. RSS is a small 1648 KiB which has been allocated for normal program startup like text area, globals, etc.
  • on the second print, we have written to 8388608 KiB == 8GiB worth of pages. As a result, RSS increased by exactly 8GIB to 8390256 KiB == 8388608 KiB + 1648 KiB
  • RSS continues to increase in 8GiB increments. The last print shows about 24 GiB of memory, and before 32 GiB could be printed, the OOM killer killed the process

OOM killer logs

Our dmesg commands have shown the OOM killer logs.

An exact interpretation of those has been asked at:

• Understanding the Linux oom-killer's logs but let's have a quick look here.
• https://serverfault.com/questions/548736/how-to-read-oom-killer-syslog-messages

The very first line of the log was:

[ 7283.479087] mongod invoked oom-killer: gfp_mask=0x6200ca(GFP_HIGHUSER_MOVABLE), order=0, oom_score_adj=0

So we see that interestingly it was the MongoDB daemon that always runs in my laptop on the background that first triggered the OOM killer, presumably when the poor thing was trying to allocate some memory.

However, the OOM killer does not necessarily kill the one who awoke it.

After the invocation, the kernel prints a table or processes including the oom_score:

[ 7283.479292] [  pid  ]   uid  tgid total_vm      rss pgtables_bytes swapents oom_score_adj name
[ 7283.479303] [    496]     0   496    16126        6   172032      484             0 systemd-journal
[ 7283.479306] [    505]     0   505     1309        0    45056       52             0 blkmapd
[ 7283.479309] [    513]     0   513    19757        0    57344       55             0 lvmetad
[ 7283.479312] [    516]     0   516     4681        1    61440      444         -1000 systemd-udevd

and further ahead we see that our own little main.out actually got killed on the previous invocation:

[ 7283.479871] Out of memory: Kill process 15665 (main.out) score 865 or sacrifice child
[ 7283.479879] Killed process 15665 (main.out) total-vm:67111332kB, anon-rss:92kB, file-rss:4kB, shmem-rss:30080832kB
[ 7283.479951] oom_reaper: reaped process 15665 (main.out), now anon-rss:0kB, file-rss:0kB, shmem-rss:30080832kB

This log mentions the score 865 which that process had, presumably the highest (worst) OOM killer score as mentioned at: https://unix.stackexchange.com/questions/153585/how-does-the-oom-killer-decide-which-process-to-kill-first

Also interestingly, everything apparently happened so fast that before the freed memory was accounted, the oom was awoken again by the DeadlineMonitor process:

[ 7283.481043] DeadlineMonitor invoked oom-killer: gfp_mask=0x6200ca(GFP_HIGHUSER_MOVABLE), order=0, oom_score_adj=0

and this time that killed some Chromium process, which is usually my computers normal memory hog:

[ 7283.481773] Out of memory: Kill process 11786 (chromium-browse) score 306 or sacrifice child
[ 7283.481833] Killed process 11786 (chromium-browse) total-vm:1813576kB, anon-rss:208804kB, file-rss:0kB, shmem-rss:8380kB
[ 7283.497847] oom_reaper: reaped process 11786 (chromium-browse), now anon-rss:0kB, file-rss:0kB, shmem-rss:8044kB

Tested in Ubuntu 19.04, Linux kernel 5.0.0.

Change the names of your inputs:

<input name="xyz[]" value="Lorem" />
<input name="xyz[]" value="ipsum"  />
<input name="xyz[]" value="dolor" />
<input name="xyz[]" value="sit" />
<input name="xyz[]" value="amet" />

Then:

$_POST['xyz'][0] == 'Lorem'
$_POST['xyz'][4] == 'amet'

If so, that would make my life ten times easier, as I could send an indefinite amount of information through a form and get it processed by the server simply by looping through the array of items with the name "xyz".

Note that this is probably the wrong solution. Obviously, it depends on the data you are sending.

Try the following:

LD_LIBRARY_PATH=/usr/local/lib /usr/local/bin/python

Replace /usr/local/lib with the folder where you have installed libpython2.7.so.1.0 if it is not in /usr/local/lib.

If this works and you want to make the changes permanent, you have two options:

1. Add export LD_LIBRARY_PATH=/usr/local/lib to your .profile in your home directory (this works only if you are using a shell which loads this file when a new shell instance is started). This setting will affect your user only.

2. Add /usr/local/lib to /etc/ld.so.conf and run ldconfig. This is a system-wide setting of course.

Arrays must have zero based integer indexes in JavaScript. So:

var valueToPush = new Array();
valueToPush[0] = productID;
valueToPush[1] = itemColorTitle;
valueToPush[2] = itemColorPath;
cookie_value_add.push(valueToPush);

Or maybe you want to use objects (which are associative arrays):

var valueToPush = { }; // or "var valueToPush = new Object();" which is the same
valueToPush["productID"] = productID;
valueToPush["itemColorTitle"] = itemColorTitle;
valueToPush["itemColorPath"] = itemColorPath;
cookie_value_add.push(valueToPush);

which is equivalent to:

var valueToPush = { };
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;
cookie_value_add.push(valueToPush);

It's a really fundamental and crucial difference between JavaScript arrays and JavaScript objects (which are associative arrays) that every JavaScript developer must understand.

1) When to use include directive ?

To prevent duplication of same output logic across multiple jsp's of the web app ,include mechanism is used ie.,to promote the re-usability of presentation logic include directive is used

  <%@ include file="abc.jsp" %>

when the above instruction is received by the jsp engine,it retrieves the source code of the abc.jsp and copy's the same inline in the current jsp. After copying translation is performed for the current page

Simply saying it is static instruction to jsp engine ie., whole source code of "abc.jsp" is copied into the current page

2) When to use include action ?

include tag doesn't include the source code of the included page into the current page instead the output generated at run time by the included page is included into the current page response

include tag functionality is similar to that of include mechanism of request dispatcher of servlet programming

include tag is run-time instruction to jsp engine ie., rather copying whole code into current page a method call is made to "abc.jsp" from current page

The code snippet in the linked proposed duplicate reads user input.

ECHO A current build of Test Harness exists.
set /p delBuild=Delete preexisting build [y/n]?: 

The user can type as many letters as they want, and it will go into the delBuild variable.

Niche Answer:

If you have a zfs pool on that device, at least when it's a file-based pool, lsof will not show the usage. But you can simply run

sudo zpool export mypoo

and then unmount.
