Programs & Examples On #Programming languages

Adding the correct link here Kebab Case

which is All lowercase with - separating words.

I have read or heard that Mac OS X is written mostly in Objective-C with some of the lower level parts, such as the kernel, and hardware device drivers written in C. I believe that Apple "eat(s) its own dog food", meaning that they write Mac OS X using their own Xcode Developer Tools. The GCC(GNU Compiler Collection) compiler-linker is the unix command line tool that xCode used for most of its compiling and/or linking of executables. Among other possible languages, I know GCC compiles source code from the C, Objective-C, C++ and Objective-C++ languages.

imagine an excel page. With columns populated with formulas to calculate you tax return.

All the logic is done declared in the cells, the order of the calculation is by determine by formula itself rather than procedurally.

That is sort of what declarative programming is all about. You declare the problem space and the solution rather than the flow of the program.

Prolog is the only declarative language I've use. It requires a different kind of thinking but it's good to learn if just to expose you to something other than the typical procedural programming language.

Because it's always that way: time pass and good things pass away too :(

But when you write asm code it's totally different feeling than when you code high-level langs, though you know it's much less productive. It's like you're a painter: you are free to draw anything you like the way you like with absolutely no restrictions(well, only by CPU features)... That is why I love it. It's a pity this language goes away. But while somebody still remembers it and codes it, it will never die!

How about alias gcc99= gcc -std=c99?

I second Kristopher's recommendation of K&R for C.

I've found the "Essential Actionscript 2.0" book quite useful for AS coding (there's an AS3 version out now I believe).

I've found that having real books to thumb through is more helpful than an online reference in some cases. Not really sure why though.

Scala is supported. See example.

Support for other languages is problematic:

7) Something like the dx tool can be forced into the phone, so that Java code could in principle continue to generate bytecodes, yet have them be translated into a VM-runnable form. But, at present, Java code cannot be generated on the fly. This means Dalvik cannot run dynamic languages (JRuby, Jython, Groovy). Yet. (Perhaps the dex format needs a detuned variant which can be easily generated from bytecodes.)

Perhaps the single biggest "benefit" of dynamic typing is the shallower learning curve. There is no type system to learn and no non-trivial syntax for corner cases such as type constraints. That makes dynamic typing accessible to a lot more people and feasible for many people for whom sophisticated static type systems are out of reach. Consequently, dynamic typing has caught on in the contexts of education (e.g. Scheme/Python at MIT) and domain-specific languages for non-programmers (e.g. Mathematica). Dynamic languages have also caught on in niches where they have little or no competition (e.g. Javascript).

The most concise dynamically-typed languages (e.g. Perl, APL, J, K, Mathematica) are domain specific and can be significantly more concise than the most concise general-purpose statically-typed languages (e.g. OCaml) in the niches they were designed for.

The main disadvantages of dynamic typing are:

• Run-time type errors.

• Can be very difficult or even practically impossible to achieve the same level of correctness and requires vastly more testing.

• No compiler-verified documentation.

• Poor performance (usually at run-time but sometimes at compile time instead, e.g. Stalin Scheme) and unpredictable performance due to dependence upon sophisticated optimizations.

Personally, I grew up on dynamic languages but wouldn't touch them with a 40' pole as a professional unless there were no other viable options.

Apart from the difference that Scripting language is Interpreted and Programming language is Compiled, there is another difference as below, which I guess has been missed..

A scripting language is a programming language that is used to manipulate, customize, and automate the facilities of an existing system. In such systems, useful functionality is already available through a user interface, and the scripting language is a mechanism for exposing that functionality to program control.

Whereas a Programming Language generally is used to code the system from Scratch.

src ECMA

A compiler, in general, reads higher level language computer code and converts it to either p-code or native machine code. An interpreter runs directly from p-code or an interpreted code such as Basic or Lisp. Typically, compiled code runs much faster, is more compact, and has already found all of the syntax errors and many of the illegal reference errors. Interpreted code only finds such errors after the application attempts to interpret the affected code. Interpreted code is often good for simple applications that will only be used once or at most a couple times, or maybe even for prototyping. Compiled code is better for serious applications. A compiler first takes in the entire program, checks for errors, compiles it and then executes it. Whereas, an interpreter does this line by line, so it takes one line, checks it for errors, and then executes it.

If you need more information, just Google for "difference between compiler and interpreter".

Since nobody has mentioned it, I'd like to add that Facebook chat is written in Erlang.

Type safety is not just a compile time constraint, but a run time constraint. I feel even after all this time, we can add further clarity to this.

There are 2 main issues related to type safety. Memory** and data type (with its corresponding operations).

Memory**

A char typically requires 1 byte per character, or 8 bits (depends on language, Java and C# store unicode chars which require 16 bits). An int requires 4 bytes, or 32 bits (usually).

Visually:

char: |-|-|-|-|-|-|-|-|

int : |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-|

A type safe language does not allow an int to be inserted into a char at run-time (this should throw some kind of class cast or out of memory exception). However, in a type unsafe language, you would overwrite existing data in 3 more adjacent bytes of memory.

int >> char:

|-|-|-|-|-|-|-|-| |?|?|?|?|?|?|?|?| |?|?|?|?|?|?|?|?| |?|?|?|?|?|?|?|?|

In the above case, the 3 bytes to the right are overwritten, so any pointers to that memory (say 3 consecutive chars) which expect to get a predictable char value will now have garbage. This causes undefined behavior in your program (or worse, possibly in other programs depending on how the OS allocates memory - very unlikely these days).

** While this first issue is not technically about data type, type safe languages address it inherently and it visually describes the issue to those unaware of how memory allocation "looks".

Data Type

The more subtle and direct type issue is where two data types use the same memory allocation. Take a int vs an unsigned int. Both are 32 bits. (Just as easily could be a char[4] and an int, but the more common issue is uint vs. int).

|-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-|

|-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-|

A type unsafe language allows the programmer to reference a properly allocated span of 32 bits, but when the value of a unsigned int is read into the space of an int (or vice versa), we again have undefined behavior. Imagine the problems this could cause in a banking program:

"Dude! I overdrafted $30 and now I have $65,506 left!!"

...'course, banking programs use much larger data types. ;) LOL!

As others have already pointed out, the next issue is computational operations on types. That has already been sufficiently covered.

Speed vs Safety

Most programmers today never need to worry about such things unless they are using something like C or C++. Both of these languages allow programmers to easily violate type safety at run time (direct memory referencing) despite the compilers' best efforts to minimize the risk. HOWEVER, this is not all bad.

One reason these languages are so computationally fast is they are not burdened by verifying type compatibility during run time operations like, for example, Java. They assume the developer is a good rational being who won't add a string and an int together and for that, the developer is rewarded with speed/efficiency.

• In a statically typed language, a variable is associated with a type which is known at compile time, and that type remains unchanged throughout the execution of a program. Equivalently, the variable can only be assigned a value which is an instance of the known/specified type.
• In a dynamically typed language, a variable has no type, and its value during execution can be anything of any shape and form.

Enqueue means to add an element, dequeue to remove an element.

var stackInput= []; // First stack
var stackOutput= []; // Second stack

// For enqueue, just push the item into the first stack
function enqueue(stackInput, item) {
  return stackInput.push(item);
}

function dequeue(stackInput, stackOutput) {
  // Reverse the stack such that the first element of the output stack is the
  // last element of the input stack. After that, pop the top of the output to
  // get the first element that was ever pushed into the input stack
  if (stackOutput.length <= 0) {
    while(stackInput.length > 0) {
      var elementToOutput = stackInput.pop();
      stackOutput.push(elementToOutput);
    }
  }

  return stackOutput.pop();
}

IT baffles me sometimes to why a software company would develop its own scripting language to interface with their software, rather than building a strong API that can interface with your scripting language of choice. My vote goes to TransCAD's scripting language.

Encapsulation is a way to achieve "information hiding" so, following your example, you don't "need to know the internal working of the mobile phone to operate" with it. You have an interface to use the device behaviour without knowing implementation details.

Abstraction on the other side, can be explained as the capability to use the same interface for different objects. Different implementations of the same interface can exist. Details are hidden by encapsulation.

Looking at the language itself may help; it often helps me (I'm not a native English speaker).

In duck typing:

1) the word typing does not mean typing on a keyboard (as was the persistent image in my mind), it means determining "what type of a thing is that thing?"

2) the word duck expresses how is that determining done; it's kind of a 'loose' determining, as in: "if it walks like a duck ... then it's a duck". It's 'loose' because the thing may be a duck or may not, but whether it actually is a duck doesn't matter; what matters is that I can do with it what I can do with ducks and expect behaviors exhibited by ducks. I can feed it bread crumbs and the thing may go towards me or charge at me or back off ... but it will not devour me like a grizzly would.

Looking for a function? Why not a language?

I love PHP but it always seems to be built like this "Oh s***t! I forgot this! Let's just add another argument to the function" which result in this :

str_replace($search, $replace, $subject, ...)
strstr($subject, $search, ...)

Notice the extra underscore and the different order for the arguments.

Here is something else

$a = array( 'a', 'b', 'c', 'd');

print_r($a); //Prints array( 0 => 'a', 1 => 'b',    2 => 'c', 3 => 'd');
unset($a[2]); //Destroys the element 2 of the list
print_r($a); //Prints array( 0 => 'a', 1 => 'b',    3 => 'd');

Start thinking in terms of a: blast from the past

Once upon a time, long long ago, there lived in the land of computing interpreters and compilers. All kinds of fuss ensued over the merits of one over the other. The general opinion at that time was something along the lines of:

• Interpreter: Fast to develop (edit and run). Slow to execute because each statement had to be interpreted into machine code every time it was executed (think of what this meant for a loop executed thousands of times).
• Compiler: Slow to develop (edit, compile, link and run. The compile/link steps could take serious time). Fast to execute. The whole program was already in native machine code.

A one or two order of magnitude difference in the runtime performance existed between an interpreted program and a compiled program. Other distinguishing points, run-time mutability of the code for example, were also of some interest but the major distinction revolved around the run-time performance issues.

Today the landscape has evolved to such an extent that the compiled/interpreted distinction is pretty much irrelevant. Many compiled languages call upon run-time services that are not completely machine code based. Also, most interpreted languages are "compiled" into byte-code before execution. Byte-code interpreters can be very efficient and rival some compiler generated code from an execution speed point of view.

The classic difference is that compilers generated native machine code, interpreters read source code and generated machine code on the fly using some sort of run-time system. Today there are very few classic interpreters left - almost all of them compile into byte-code (or some other semi-compiled state) which then runs on a virtual "machine".

Functional programming has been around for a long time, since LISP was one of the earliest languages to have a compiler, and since MIT's LISP machines. It's not a new paradigm (OO is much newer) but the dominant software platforms have tended to be written in languages that translate easily to assembly language, and their APIs heavily favor imperative code (UNIX with C, Windows with C, and Macintosh with Pascal and later C).

I think the new innovation in the last few years is for a diversity of APIs to catch on, particularly for things like web development where the platform APIs are irrelevant. Since you're not coding directly to the Win32 API or the POSIX API, that gives people the freedom to try out functional languages.

If you google for sort order windows explorer you will find out that Windows Explorer (since Windows XP) obviously uses the function StrCmpLogicalW in the sort order "by name". I did not find information about the treatment of the underscore character. I was amused by the following note in the documentation:

Behavior of this function, and therefore the results it returns, can change from release to release. ...

You have to replace the values one by one such as in a for-loop or copying another array over another such as using memcpy(..) or std::copy

e.g.

for (int i = 0; i < arrayLength; i++) {
    array[i] = newValue[i];
}

Take care to ensure proper bounds-checking and any other checking that needs to occur to prevent an out of bounds problem.

I think people in this post are missing the most important point for anyone who has never used a functional programming language: expanding your mind. If you are new to functional programming then Haskell will make you think in ways you've never thought before. As a result your programming in other areas and other languages will improve. How much? Hard to quantify.

The definition of "scripting language" is pretty fuzzy. I'd base it on the following considerations:

1. Scripting languages don't usually have user-visible compile steps. Typically the user can just run programs in one easy command.

2. Programs in scripting languages are normally passed around in source form.

3. Scripting languages normally have runtimes that are present on a large number of systems, and the runtimes can be installed easily on most systems.

4. Scripting languages tend to be cross-platform and not machine-specific.

5. Scripting languages make it easy to call other programs and interface with the operating system.

6. Scripting languages are usually easily embeddable into larger systems written in more conventional programming languages.

7. Scripting languages are normally designed for ease of programming, and with much less regard for execution speed. (If you want fast execution, the usual advice is to code the time-consuming parts in something like C, and either embed the language into C or call C bits from the language.)

Some of the characteristics I listed above are true of implementations, in which case I'm referring to the more common implementations. There have been C interpreters, with (AFAIK) no obvious compile step, but that's not true of most C implementations. You could certainly compile a Perl program to native code, but that's not how it's normally used. Some other characteristics are social in nature. Some of the above criteria overlap somewhat. As I said, the definition is fuzzy.

Don't confuse thread safety with determinism. Thread-safe code can also be non-deterministic. Given the difficulty of debugging problems with threaded code, this is probably the normal case. :-)

Thread safety simply ensures that when a thread is modifying or reading shared data, no other thread can access it in a way that changes the data. If your code depends on a certain order for execution for correctness, then you need other synchronization mechanisms beyond those required for thread safety to ensure this.

Wikipedia has the answer. Read syntax (programming languages) & semantics (computer science) wikipages.

Or think about the work of any compiler or interpreter. The first step is lexical analysis where tokens are generated by dividing string into lexemes then parsing, which build some abstract syntax tree (which is a representation of syntax). The next steps involves transforming or evaluating these AST (semantics).

Also, observe that if you defined a variant of C where every keyword was transformed into its French equivalent (so if becoming si, do becoming faire, else becoming sinon etc etc...) you would definitely change the syntax of your language, but you won't change much the semantics: programming in that French-C won't be easier!

Sudo is a Unix specific command designed to allow a user to carry out administrative tasks with the appropriate permissions.

Windows does not have (need?) this.

Run the command with the sudo removed from the start.

A simple solution that works for pages without any query parameters, is browser back / forward, router and deep-linking compliant.

<a (click)="jumpToId('anchor1')">Go To Anchor 1</a>


ngOnInit() {

    // If your page is dynamic
    this.yourService.getWhatever()
        .then(
            data => {
            this.componentData = data;
            setTimeout(() => this.jumpToId( window.location.hash.substr(1) ), 100);
        }
    );

    // If your page is static
    // this.jumpToId( window.location.hash.substr(1) )
}

jumpToId( fragment ) {

    // Use the browser to navigate
    window.location.hash = fragment;

    // But also scroll when routing / deep-linking to dynamic page
    // or re-clicking same anchor
    if (fragment) {
        const element = document.querySelector('#' + fragment);
        if (element) element.scrollIntoView();
    }
}

The timeout is simply to allow the page to load any dynamic data "protected" by an *ngIf. This can also be used to scroll to the top of the page when changing route - just provide a default top anchor tag.

You can aliasing both query and Selecting them in the select query

Roman Samoylenko's answer was correct except the function has changed. The correct answer is

Glide.with(context)
                .load(yourImage)
                .apply(RequestOptions.circleCropTransform())
                .into(imageView);

Choosing the location to save the file before creating it is not possible. But it is possible, at least in Chrome, to generate files using just JavaScript. Here is an old example of mine of creating a CSV file. The user will be prompted to download it. This, unfortunately, does not work well in other browsers, especially IE.

<!DOCTYPE html>
<html>
<head>
    <title>JS CSV</title>
</head>
<body>
    <button id="b">export to CSV</button>
    <script type="text/javascript">
        function exportToCsv() {
            var myCsv = "Col1,Col2,Col3\nval1,val2,val3";

            window.open('data:text/csv;charset=utf-8,' + escape(myCsv));
        }

        var button = document.getElementById('b');
        button.addEventListener('click', exportToCsv);
    </script>
</body>
</html>

I will soon released a new version of my app to support to galaxy ace.

You can download here: https://play.google.com/store/apps/details?id=droid.pr.coolflashlightfree

In order to solve your problem you should do this:

this._camera = Camera.open();     
this._camera.startPreview();
this._camera.autoFocus(new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera camera) {
}
});

Parameters params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_ON);
this._camera.setParameters(params);

params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
this._camera.setParameters(params);

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera

For applications such as games and embedded systems where memory and performance are both critical, float is usually the numeric type of choice as it is faster and half the size of a double. Integers used to be the weapon of choice, but floating point performance has overtaken integer in modern processors. Decimal is right out!

First, we're talking about packaging a Node.js app for workshops, demos, etc. where it can be handy to have an app "just running" without the need for the end user to care about installation and dependencies.

You can try the following setup:

1. Get your apps source code
2. npm install all dependencies (via package.json) to the local node_modules directory. It is important to perform this step on each platform you want to support separately, in case of binary dependencies.
3. Copy the Node.js binary – node.exe on Windows, (probably) /usr/local/bin/node on OS X/Linux to your project's root folder. On OS X/Linux you can find the location of the Node.js binary with which node.

For Windows:
Create a self extracting archive, 7zip_extra supports a way to execute a command right after extraction, see: http://www.msfn.org/board/topic/39048-how-to-make-a-7-zip-switchless-installer/.

For OS X/Linux:
You can use tools like makeself or unzipsfx (I don't know if this is compiled with CHEAP_SFX_AUTORUN defined by default).

These tools will extract the archive to a temporary directory, execute the given command (e.g. node app.js) and remove all files when finished.

To append a new data element,just do this...

Document doc = docBuilder.parse(is);        
Node root=doc.getFirstChild();
Element newserver=doc.createElement("new_server");
root.appendChild(newserver);

easy.... 'is' is an InputStream object. rest is similar to your code....tried it just now...

Try this:

var array = [1, 55, 77, 88, 76, 59];
var array_last_five;
array_last_five = array.slice(-5);
if (array.length < 6) {
     array_last_five.shift();
}

In Oracle 12c and above, we have two types of databases:

1. Container DataBase (CDB), and
2. Pluggable DataBase (PDB).

If you want to create an user, you have two possibilities:

1. You can create a "container user" aka "common user".
   Common users belong to CBDs as well as to current and future PDBs. It means they can perform operations in Container DBs or Pluggable DBs according to assigned privileges.

   create user c##username identified by password;

2. You can create a "pluggable user" aka "local user".
   Local users belong only to a single PDB. These users may be given administrative privileges, but only for that PDB inside which they exist. For that, you should connect to pluggable datable like that:

   alter session set container = nameofyourpluggabledatabase;

   and there, you can create user like usually:

   create user username identified by password;

Don't forget to specify the tablespace(s) to use, it can be useful during import/export of your DBs. See this for more information about it https://docs.oracle.com/database/121/SQLRF/statements_8003.htm#SQLRF01503

There is one common answer I haven't see here yet, which is the Window Function. It is an alternative to the correlated sub-query, if your DB supports it.

SELECT sensorID,timestamp,sensorField1,sensorField2 
FROM (
    SELECT sensorID,timestamp,sensorField1,sensorField2
        , ROW_NUMBER() OVER(
            PARTITION BY sensorID
            ORDER BY timestamp
        ) AS rn
    FROM sensorTable s1
WHERE rn = 1
ORDER BY sensorID, timestamp;

I acually use this more than correlated sub-queries. Feel free to bust me in the comments over effeciancy, I'm not too sure how it stacks up in that regard.

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

Specify the column's type as type: 'date':

{title: 'Expiration Date', data: 'ExpirationDate', type: 'date'}

I've got one more additional option to get value by id:

var idElement = document.getElementById("idName");
var selectedValue = idElement.options[idElement.selectedIndex].value;

It's a simple JavaScript solution.

You can use following formulas.

For Excel 2007 or later:

=IFERROR(VLOOKUP(D3,List!A:C,3,FALSE),"No Match")

For Excel 2003:

=IF(ISERROR(MATCH(D3,List!A:A, 0)), "No Match", VLOOKUP(D3,List!A:C,3,FALSE))

Note, that

• I'm using List!A:C in VLOOKUP and returns value from column ? 3
• I'm using 4th argument for VLOOKUP equals to FALSE, in that case VLOOKUP will only find an exact match, and the values in the first column of List!A:C do not need to be sorted (opposite to case when you're using TRUE).

As solution could be also considering encoding to a format which doesn't contain symbol., as base64.

In js should be added

btoa(parameter); 

In controller

byte[] bytes = Convert.FromBase64String(parameter);
string parameter= Encoding.UTF8.GetString(bytes);

Like R. Bemrose suggested, if you are doing Windows 7 specific features, you should look at the Windows® API Code Pack for Microsoft® .NET Framework.

It contains a CoreHelpers class that let you determine the OS you are currently on (XP and above only, its a requirement for .NET nowaday)

It also provide multiple helper methods. For example, suppose that you want to use the jump list of Windows 7, there is a class TaskbarManager that provide a property called IsPlatformSupported and it will return true if you are on Windows 7 and above.

https://firebase.google.com/docs/auth/web/manage-users

You have to add an auth state change observer.

firebase.auth().onAuthStateChanged(function(user) {
  if (user) {
    // User is signed in.
  } else {
    // No user is signed in.
  }
});

How's this for a work around (using an actual table)?

table {
    border-collapse: collapse;
}

tr.row {
    border-bottom: solid white 30px; /* change "white" to your background color */
}

It's not as dynamic, since you have to explicitly set the color of the border (unless there's a way around that too), but this is something I'm experimenting with on a project of my own.

Edit to include comments regarding transparent:

tr.row {
    border-bottom: 30px solid transparent;
}

If without '0x' prefix:

'{0:x}'.format(int(dec))

else use built-in hex() funtion.

I would like to give an example which I tried by understanding above documentation and works correctly. If you wish to apply 25% padding on left and right sides medium screen size then please use px-md-1. It works as desired and can similarly follow for other screen sizes. :)

IMHO, the key for understanding recursion-related actions is:

1. First, we dive into stack recursively, and with every call we somehow modify a value (e.g. n-1 in func(n-1);) which determines whether the recursion should go deeper and deeper.
2. Once recursionStopCondition is met (e.g. n == 0), the recursions stops, and methods do actual work and return values to the caller method in upper stacks, thus bubbling to the top of the stack.
3. It is important to catch the value returned from deeper stack, somehow modify it (multiplying by n in your case), and then return this modified value topwards the stack. The common mistake is that the value from the deepest stack frame is returned straight to the top of the stack, so that all method invocations are ignored.

Surely, methods can do useful work before they dive into recursion (from the top to the bottom of the stack), or on the way back.

Here is a simple web crawler, i used BeautifulSoup and we will search for all the links(anchors) who's class name is _3NFO0d. I used Flipkar.com, it is an online retailing store.

import requests
from bs4 import BeautifulSoup
def crawl_flipkart():
    url = 'https://www.flipkart.com/'
    source_code = requests.get(url)
    plain_text = source_code.text
    soup = BeautifulSoup(plain_text, "lxml")
    for link in soup.findAll('a', {'class': '_3NFO0d'}):
        href = link.get('href')
        print(href)

crawl_flipkart()

You don't need the "eval" even. Just put a dollar sign in front of the string:

cmd="ls"
$cmd

Just go to web.config file and add following

<system.webServer>
    <defaultDocument>
      <files>
        <clear />
        <add value="Path of your Page" />
      </files>
    </defaultDocument>
</system.webServer>

int is a C# keyword and is unambiguous.

Most of the time it doesn't matter but two things that go against Int32:

• You need to have a "using System;" statement. using "int" requires no using statement.
• It is possible to define your own class called Int32 (which would be silly and confusing). int always means int.

You could try

DF <- data.frame("a" = as.character(0:5),
                 "b" = paste(0:5, ".1", sep = ""),
                 "c" = letters[1:6],
                 stringsAsFactors = FALSE)

# Check columns classes
sapply(DF, class)

#           a           b           c 
# "character" "character" "character" 

cols.num <- c("a","b")
DF[cols.num] <- sapply(DF[cols.num],as.numeric)
sapply(DF, class)

#          a           b           c 
#  "numeric"   "numeric" "character"

This is what I used to accomplish to this:

System.IO.Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, System.AppDomain.CurrentDomain.RelativeSearchPath ?? "");

Why not do a where IN a sub-select...

then...

There is now a plugin (since end of 2012) that can take care of this: gensth/ProjectLocationUpdater on GitHub.

This cannot be done with pure HTML. You must rely on JavaScript for this trick.

However, if you place two forms on the HTML page you can do this.

Form1 would have the previous button.

Form2 would have any user inputs + the next button.

When the user presses Enter in Form2, the Next submit button would fire.

1 - remove the margin from your BODY CSS.

2 - wrap all of your html in a wrapper <div id="wrapper"> ... all your body content </div>

3 - Define the CSS for the wrapper:

This will hold everything together, centered on the page.

#wrapper {
    margin-left:auto;
    margin-right:auto;
    width:960px;
}

There's more than one way to skin this problem so here's my solution:

1. Use Select() to convert the key-value pair to a string;
2. Convert to a list of strings;
3. Write out to the console using ForEach().

dict.Select(i => $"{i.Key}: {i.Value}").ToList().ForEach(Console.WriteLine);

the best solution here

class Category(var Id: Int,var Name: String)
arrayList is Category list
val selectedPositon=arrayList.map { x->x.Id }.indexOf(Category_Id)
spinner_update_categories.setSelection(selectedPositon)

help('nonlocal') The nonlocal statement

---

    nonlocal_stmt ::= "nonlocal" identifier ("," identifier)*

The nonlocal statement causes the listed identifiers to refer to previously bound variables in the nearest enclosing scope. This is important because the default behavior for binding is to search the local namespace first. The statement allows encapsulated code to rebind variables outside of the local scope besides the global (module) scope.

Names listed in a nonlocal statement, unlike to those listed in a global statement, must refer to pre-existing bindings in an enclosing scope (the scope in which a new binding should be created cannot be determined unambiguously).

Names listed in a nonlocal statement must not collide with pre- existing bindings in the local scope.

However, I got curious to what each class contained and when I try to open one of the classes in the jar file, it tells me that I need a source file.

A jar file is basically a zip file containing .class files and potentially other resources (and metadata about the jar itself). It's hard to compare C to Java really, as Java byte code maintains a lot more metadata than most binary formats - but the class file is compiled code instead of source code.

If you either open the jar file with a zip utility or run jar xf foo.jar you can extract the files from it, and have a look at them. Note that you don't need a jar file to run Java code - classloaders can load class data directly from the file system, or from URLs, as well as from jar files.

The java.util.logging.Level documentation does a good job of defining when to use a log level and the target audience of that log level.

Most of the confusion with java.util.logging is in the tracing methods. It should be in the class level documentation but instead the Level.FINE field provides a good overview:

FINE is a message level providing tracing information. All of FINE, FINER, and FINEST are intended for relatively detailed tracing. The exact meaning of the three levels will vary between subsystems, but in general, FINEST should be used for the most voluminous detailed output, FINER for somewhat less detailed output, and FINE for the lowest volume (and most important) messages. In general the FINE level should be used for information that will be broadly interesting to developers who do not have a specialized interest in the specific subsystem. FINE messages might include things like minor (recoverable) failures. Issues indicating potential performance problems are also worth logging as FINE.

One important thing to understand which is not mentioned in the level documentation is that call-site tracing information is logged at FINER.

• Logger#entering A LogRecord with message "ENTRY", log level FINER, ...
• Logger#throwing The logging is done using the FINER level...The LogRecord's message is set to "THROW"
• Logger#exiting A LogRecord with message "RETURN", log level FINER...

If you log a message as FINE you will be able to configure logging system to see the log output with or without tracing log records surrounding the log message. So use FINE only when tracing log records are not required as context to understand the log message.

FINER indicates a fairly detailed tracing message. By default logging calls for entering, returning, or throwing an exception are traced at this level.

In general, most use of FINER should be left to call of entering, exiting, and throwing. That will for the most part reserve FINER for call-site tracing when verbose logging is turned on. When swallowing an expected exception it makes sense to use FINER in some cases as the alternative to calling trace throwing method since the exception is not actually thrown. This makes it look like a trace when it isn't a throw or an actual error that would be logged at a higher level.

FINEST indicates a highly detailed tracing message.

Use FINEST when the tracing log message you are about to write requires context information about program control flow. You should also use FINEST for tracing messages that produce large amounts of output data.

CONFIG messages are intended to provide a variety of static configuration information, to assist in debugging problems that may be associated with particular configurations. For example, CONFIG message might include the CPU type, the graphics depth, the GUI look-and-feel, etc.

The CONFIG works well for assisting system admins with the items listed above.

Typically INFO messages will be written to the console or its equivalent. So the INFO level should only be used for reasonably significant messages that will make sense to end users and system administrators.

Examples of this are tracing program startup and shutdown.

In general WARNING messages should describe events that will be of interest to end users or system managers, or which indicate potential problems.

An example use case could be exceptions thrown from AutoCloseable.close implementations.

In general SEVERE messages should describe events that are of considerable importance and which will prevent normal program execution. They should be reasonably intelligible to end users and to system administrators.

For example, if you have transaction in your program where if any one of the steps fail then all of the steps voided then SEVERE would be appropriate to use as the log level.

With Homebrew already installed on your Mac, you can easily install ngrok from the terminal, using this command:

$ brew cask install ngrok

Then run it from the shell using this command:

$ ngrok http 8000

With this command, you're telling ngrok to basically create a tunnel to your localhost 8000 and assign an internet name host for it. And thats it. You should be good to go.

To change or remove the passphrase, I often find it simplest to pass in only the p and f flags, then let the system prompt me to supply the passphrases:

ssh-keygen -p -f <name-of-private-key>

For instance:

ssh-keygen -p -f id_rsa

Enter an empty password if you want to remove the passphrase.

A sample run to remove or change a password looks something like this:

ssh-keygen -p -f id_rsa
Enter old passphrase: 
Key has comment 'bcuser@pl1909'
Enter new passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved with the new passphrase.

When adding a passphrase to a key that has no passphrase, the run looks something like this:

ssh-keygen -p -f id_rsa
Key has comment 'charlie@elf-path'
Enter new passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved with the new passphrase.

Personally I would suggest this is an error as opposed to a setting that needs adjusting. In my code it was because I had a class that had the same name as a library within one of my controllers and it seemed to trip it up.

A lot of other answers are focusing on a pattern that does work, but their explanations aren't really very thorough as to why your current code doesn't work.

Your code, for reference:

function funcName() {
    alert("test");
}

var func = funcName();
var run = setInterval("func",10000)

Let's break this up into chunks. Your function funcName is fine. Note that when you call funcName (in other words, you run it) you will be alerting "test". But notice that funcName() -- the parentheses mean to "call" or "run" the function -- doesn't actually return a value. When a function doesn't have a return value, it defaults to a value known as undefined.

When you call a function, you append its argument list to the end in parentheses. When you don't have any arguments to pass the function, you just add empty parentheses, like funcName(). But when you want to refer to the function itself, and not call it, you don't need the parentheses because the parentheses indicate to run it.

So, when you say:

var func = funcName();

You are actually declaring a variable func that has a value of funcName(). But notice the parentheses. funcName() is actually the return value of funcName. As I said above, since funcName doesn't actually return any value, it defaults to undefined. So, in other words, your variable func actually will have the value undefined.

Then you have this line:

var run = setInterval("func",10000)

The function setInterval takes two arguments. The first is the function to be ran every so often, and the second is the number of milliseconds between each time the function is ran.

However, the first argument really should be a function, not a string. If it is a string, then the JavaScript engine will use eval on that string instead. So, in other words, your setInterval is running the following JavaScript code:

func
// 10 seconds later....
func
// and so on

However, func is just a variable (with the value undefined, but that's sort of irrelevant). So every ten seconds, the JS engine evaluates the variable func and returns undefined. But this doesn't really do anything. I mean, it technically is being evaluated every 10 seconds, but you're not going to see any effects from that.

The solution is to give setInterval a function to run instead of a string. So, in this case:

var run = setInterval(funcName, 10000);

Notice that I didn't give it func. This is because func is not a function in your code; it's the value undefined, because you assigned it funcName(). Like I said above, funcName() will call the function funcName and return the return value of the function. Since funcName doesn't return anything, this defaults to undefined. I know I've said that several times now, but it really is a very important concept: when you see funcName(), you should think "the return value of funcName". When you want to refer to a function itself, like a separate entity, you should leave off the parentheses so you don't call it: funcName.

So, another solution for your code would be:

var func = funcName;
var run = setInterval(func, 10000);

However, that's a bit redundant: why use func instead of funcName?

Or you can stay as true as possible to the original code by modifying two bits:

var func = funcName;
var run = setInterval("func()", 10000);

In this case, the JS engine will evaluate func() every ten seconds. In other words, it will alert "test" every ten seconds. However, as the famous phrase goes, eval is evil, so you should try to avoid it whenever possible.

Another twist on this code is to use an anonymous function. In other words, a function that doesn't have a name -- you just drop it in the code because you don't care what it's called.

setInterval(function () {
    alert("test");
}, 10000);

In this case, since I don't care what the function is called, I just leave a generic, unnamed (anonymous) function there.

Angular 2, 4 and Angular 5 compatible!

You have provided so few details, so I'll try to answer your question without them.

You can use Interpolation:

<img src={{imagePath}} />

Or you can use a template expression:

<img [src]="imagePath" />

In a ngFor loop it might look like this:

<div *ngFor="let student of students">
   <img src={{student.ImagePath}} />
</div>

You may use the following functions which I wrote in one of my helper class in a project.

just call

showShareActivity(msg:"message", image: nil, url: nil, sourceRect: nil) 

and it will work for both iPhone and iPad. If you pass any view's CGRect value by sourceRect it will also shows a little arrow in iPad.

func topViewController()-> UIViewController{
    var topViewController:UIViewController = UIApplication.shared.keyWindow!.rootViewController!

    while ((topViewController.presentedViewController) != nil) {
        topViewController = topViewController.presentedViewController!;
    }

    return topViewController
}

func showShareActivity(msg:String?, image:UIImage?, url:String?, sourceRect:CGRect?){
    var objectsToShare = [AnyObject]()

    if let url = url {
        objectsToShare = [url as AnyObject]
    }

    if let image = image {
        objectsToShare = [image as AnyObject]
    }

    if let msg = msg {
        objectsToShare = [msg as AnyObject]
    }

    let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
    activityVC.modalPresentationStyle = .popover
    activityVC.popoverPresentationController?.sourceView = topViewController().view
    if let sourceRect = sourceRect {
        activityVC.popoverPresentationController?.sourceRect = sourceRect
    }

    topViewController().present(activityVC, animated: true, completion: nil)
}

Step 1: Open an elevated Task Scheduler (ie. right-click on the Task Scheduler icon and choose Run as administrator)

Step 2: In the Actions pane (right pane, not the actions tab), click Enable All Tasks History

That's it. Not sure why this isn't on by default, but it isn't.

In the first two cases, you simply forgot to actually call the member function (!, it's not a value) std::vector<int>::size like this:

#include <vector>

int main () {
    std::vector<int> v;
    auto size = v.size();
}

Your third call

int size = v.size();

triggers a warning, as not every return value of that function (usually a 64 bit unsigned int) can be represented as a 32 bit signed int.

int size = static_cast<int>(v.size());

would always compile cleanly and also explicitly states that your conversion from std::vector::size_type to int was intended.

Note that if the size of the vector is greater than the biggest number an int can represent, size will contain an implementation defined (de facto garbage) value.

Going back to the original question (4 years later), rather than rebuilding your own section header, iOS can simply call you (with willDisplayHeaderView:forSection:) right after it's built the default one. For example, I wanted to add a graph button on right edge of section header:

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
    UITableViewHeaderFooterView * header = (UITableViewHeaderFooterView *) view;
    if (header.contentView.subviews.count >  0) return; //in case of reuse
    CGFloat rightEdge = CGRectGetMaxX(header.contentView.bounds);
    UIButton * button = [[UIButton alloc] initWithFrame:CGRectMake(rightEdge - 44, 0, 44, CGRectGetMaxY(header.contentView.bounds))];
    [button setBackgroundImage:[UIImage imageNamed:@"graphIcon"] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(graphButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
    [view addSubview:button];
}

You don't want to delete if you're wanting to leave the row itself intact. You want to update the row, and change the column value.

The general form for this would be an UPDATE statement:

UPDATE <table name>
SET
    ColumnA = <NULL, or '', or whatever else is suitable for the new value for the column>
WHERE
    ColumnA = <bad value> /* or any other search conditions */

Here is what fixed the problem for me. I did not have to convert to Excel. Just modified the DataType when choosing the data source to "text stream" (Figure 1). You can also check the "Edit Mappings" dialog to verify the change to the size (Figure 2).

I tried many ways but this works.

One way to do it if tagID values are known upfront is to use conditional aggregation

SELECT TimeSeconds,
       COALESCE(MAX(CASE WHEN TagID = 'A1' THEN Value END), 'n/a') A1,
       COALESCE(MAX(CASE WHEN TagID = 'A2' THEN Value END), 'n/a') A2,
       COALESCE(MAX(CASE WHEN TagID = 'A3' THEN Value END), 'n/a') A3,
       COALESCE(MAX(CASE WHEN TagID = 'A4' THEN Value END), 'n/a') A4
  FROM table1
 GROUP BY TimeSeconds

or if you're OK with NULL values instead of 'n/a'

SELECT TimeSeconds,
       MAX(CASE WHEN TagID = 'A1' THEN Value END) A1,
       MAX(CASE WHEN TagID = 'A2' THEN Value END) A2,
       MAX(CASE WHEN TagID = 'A3' THEN Value END) A3,
       MAX(CASE WHEN TagID = 'A4' THEN Value END) A4
  FROM table1
 GROUP BY TimeSeconds

or with PIVOT

SELECT TimeSeconds, A1, A2, A3, A4
  FROM
(
  SELECT TimeSeconds, TagID, Value
    FROM table1
) s
PIVOT
(
  MAX(Value) FOR TagID IN (A1, A2, A3, A4)
) p

Output (with NULLs):

TimeSeconds A1      A2     A3    A4
----------- ------- ------ ----- -----
1378700244  3.75    NULL   NULL  NULL
1378700245  30.00   NULL   NULL  NULL
1378700304  1.20    NULL   NULL  NULL
1378700305  NULL    56.00  NULL  NULL
1378700344  NULL    11.00  NULL  NULL
1378700345  NULL    NULL   0.53  NULL
1378700364  4.00    NULL   NULL  NULL
1378700365  14.50   NULL   NULL  NULL
1378700384  144.00  NULL   NULL  10.00

If you have to figure TagID values out dynamically then use dynamic SQL

DECLARE @cols NVARCHAR(MAX), @sql NVARCHAR(MAX)

SET @cols = STUFF((SELECT DISTINCT ',' + QUOTENAME(TagID)
            FROM Table1
            ORDER BY 1
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)'),1,1,'')

SET @sql = 'SELECT TimeSeconds, ' + @cols + '
              FROM
            (
              SELECT TimeSeconds, TagID, Value
                FROM table1
            ) s
            PIVOT
            (
              MAX(Value) FOR TagID IN (' + @cols + ')
            ) p'

EXECUTE(@sql)

McGarnagle has a great answer, and you'll want to be accepting his, but I thought I'd mention (since you asked) how databinding works.

It's generally implemented by firing events whenever a change is made to the data, which then causes listeners (e.g. the UI) to be updated.

Two-way binding works by doing this twice, with a bit of care taken to ensure that you don't wind up stuck in an event loop (where the update from the event causes another event to be fired).

I was gonna put this in a comment, but it was getting pretty long...

AFAIK, you cannot, without actually deep-counting the size of each member in bytes. But again, does the size of a member (like elements inside a collection) count towards the size of the object, or a pointer to that member count towards the size of the object? Depends on how you define it.

I have run into this situation before where I wanted to limit the objects in my cache based on the memory they consumed.

Well, if there is some trick to do that, I'd be delighted to know about it!

Use @ViewChildren from @angular/core to get a reference to the components

template

<div *ngFor="let v of views">
    <customcomponent #cmp></customcomponent>
</div>

component

import { ViewChildren, QueryList } from '@angular/core';

/** Get handle on cmp tags in the template */
@ViewChildren('cmp') components:QueryList<CustomComponent>;

ngAfterViewInit(){
    // print array of CustomComponent objects
    console.log(this.components.toArray());
}

l?i?v?e? ?d?e?m?o?

Using Date object guarantees that. For eg if you try to create April 31st :

new Date(2014,3,31)        // Thu May 01 2014 00:00:00

Please note that it's zero indexed, so Jan. is 0, Feb. is 1 etc.

In python3, there is a bytes() method that is in the same format as encode().

str1 = b'hello world'
str2 = bytes("hello world", encoding="UTF-8")
print(str1 == str2) # Returns True

I didn't read anything about this in the docs, but perhaps I wasn't looking in the right place. This way you can explicitly turn strings into byte streams and have it more readable than using encode and decode, and without having to prefex b in front of quotes.

The answers above point out how the block size can impact performance and suggest a common heuristic for its choice based on occupancy maximization. Without wanting to provide the criterion to choose the block size, it would be worth mentioning that CUDA 6.5 (now in Release Candidate version) includes several new runtime functions to aid in occupancy calculations and launch configuration, see

CUDA Pro Tip: Occupancy API Simplifies Launch Configuration

One of the useful functions is cudaOccupancyMaxPotentialBlockSize which heuristically calculates a block size that achieves the maximum occupancy. The values provided by that function could be then used as the starting point of a manual optimization of the launch parameters. Below is a little example.

    size_t  dynamicSMemSize = 0,
    int     blockSizeLimit = 0)
{
    return cudaOccupancyMaxPotentialBlockSizeVariableSMem(minGridSize, blockSize, func, __cudaOccupancyB2DHelper(dynamicSMemSize), blockSizeLimit);
}

The meanings for the parameters is the following

minGridSize     = Suggested min grid size to achieve a full machine launch.
blockSize       = Suggested block size to achieve maximum occupancy.
func            = Kernel function.
dynamicSMemSize = Size of dynamically allocated shared memory. Of course, it is known at runtime before any kernel launch. The size of the statically allocated shared memory is not needed as it is inferred by the properties of func.
blockSizeLimit  = Maximum size for each block. In the case of 1D kernels, it can coincide with the number of input elements.

Note that, as of CUDA 6.5, one needs to compute one's own 2D/3D block dimensions from the 1D block size suggested by the API.

Note also that the CUDA driver API contains functionally equivalent APIs for occupancy calculation, so it is possible to use cuOccupancyMaxPotentialBlockSize in driver API code in the same way shown for the runtime API in the example above.

I needed to reuse the same iframe and replace the content each time. I've tried a few ways and this worked for me:

// Set the iframe's src to about:blank so that it conforms to the same-origin policy 
iframeElement.src = "about:blank";

// Set the iframe's new HTML
iframeElement.contentWindow.document.open();
iframeElement.contentWindow.document.write(newHTML);
iframeElementcontentWindow.document.close();

Here it is as a function:

function replaceIframeContent(iframeElement, newHTML)
{
    iframeElement.src = "about:blank";
    iframeElement.contentWindow.document.open();
    iframeElement.contentWindow.document.write(newHTML);
    iframeElement.contentWindow.document.close();
}

Once you have downloaded the Flutter SDK for your specific OS.

Unzip the file. Copy it to a better place. Your Flutter SDK path should be a_better_place/flutter. These would be used in tools such as VSCode or Android Studio.

For command line, you would add a_better_place/flutter/bin. Such as export PATH=a_better_place/flutter/bin:$PATH

I have found this to be really useful:

df = pd.DataFrame({'A' : range(0,10) * 2, 'B' : np.random.randint(20,30,20)})

# A ascending, B descending
df.sort(**skw(columns=['A','-B']))

# A descending, B ascending
df.sort(**skw(columns=['-A','+B']))

Note that unlike the standard columns=,ascending= arguments, here column names and their sort order are in the same place. As a result your code gets a lot easier to read and maintain.

Note the actual call to .sort is unchanged, skw (sortkwargs) is just a small helper function that parses the columns and returns the usual columns= and ascending= parameters for you. Pass it any other sort kwargs as you usually would. Copy/paste the following code into e.g. your local utils.py then forget about it and just use it as above.

# utils.py (or anywhere else convenient to import)
def skw(columns=None, **kwargs):
    """ get sort kwargs by parsing sort order given in column name """
    # set default order as ascending (+)
    sort_cols = ['+' + col if col[0] != '-' else col for col in columns]
    # get sort kwargs
    columns, ascending = zip(*[(col.replace('+', '').replace('-', ''), 
                                False if col[0] == '-' else True) 
                               for col in sort_cols])
    kwargs.update(dict(columns=list(columns), ascending=ascending))
    return kwargs

In my case after downgrading from .NET 4.5 to .NET 4.0 project was working fine on a local machine, but was failing on server after publishing.

Turns out that destination had some old assemblies, which were still referencing .NET 4.5.

Fixed it by enabling publishing option "Delete all existing files prior to publish"

I have just had all the script variations tested by Pui Cdm, included answers above and many others using php, htaccess, server configuration, and Javascript, the results are that the script

<script type="text/javascript">        
function showProtocall() {
        if (window.location.protocol != "https") {
            window.location = "https://" + window.location.href.substring(window.location.protocol.length, window.location.href.length);
            window.location.reload();
        }
    }
    showProtocall();
</script> 

provided by vivek-srivastava works best and you can add further security in java script.

I had this problem too but preferred to prevent negative margins hacks, so I put a

<div class="supercontainer"></div>

around it all which has paddings instead of margins. Of course this means more divitis but it's probably the cleanest way to do get this done properly.

I ran across the same issue this morning. It turned out to be a simple issue. I had a query window open that was set to the single user database in the object explorer. The sp_who2 stored procedure did not show then connection. Once I closed it, I was able to set it to

This might be a bit of a hack, but I avoided the issue and converted the json into PHP's POST array on the server side:

$_POST = json_decode(file_get_contents('php://input'), true);

You should implement the IEnumerable interface (CarBootSaleList should impl it in your case).

http://msdn.microsoft.com/en-us/library/system.collections.ienumerable.getenumerator.aspx

But it is usually easier to subclass System.Collections.ObjectModel.Collection and friends

http://msdn.microsoft.com/en-us/library/system.collections.objectmodel.aspx

Your code also seems a bit strange, like you are nesting lists?

Import the Support Libraries, In your project's build.gradle file, add the following lines in the project's dependencies:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    compile 'com.android.support:design:22.2.0'
    compile 'com.android.support:appcompat-v7:22.2.0'
}

Use following TextInputLayout in your UI Layout:

<android.support.design.widget.TextInputLayout
    android:id="@+id/usernameWrapper"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <EditText
        android:id="@+id/username"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textEmailAddress"
        android:hint="Username"/>

</android.support.design.widget.TextInputLayout>

Than, call setHint on TextInputLayout just after setContentView call because, to animate the floating label, you just need to set a hint, using the setHint method.

final TextInputLayout usernameWrapper = (TextInputLayout) findViewById(R.id.usernameWrapper);
usernameWrapper.setHint("Username");

For example if you have image in folder res/image.png you can write:

try
{
    ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
    InputStream input = classLoader.getResourceAsStream("image.png");
    // URL input = classLoader.getResource("image.png"); // <-- You can use URL class too.
    BufferedImage image = ImageIO.read(input);

    button.setIcon(new ImageIcon(image));
}
catch(IOException e)
{
    e.printStackTrace();
}

In one line:

try
{
    button.setIcon(new ImageIcon(ImageIO.read(Thread.currentThread().getContextClassLoader().getResourceAsStream("image.png"))));
}
catch(IOException e)
{
    e.printStackTrace();
}

If the image is bigger than button then it will not shown.

You can do this with JQueryUI:

$('a').mouseenter(function(){
  $(this).animate({
    color: '#ff0000'
  }, 1000);
}).mouseout(function(){
  $(this).animate({
    color: '#000000'
  }, 1000);
});

The basic difference is that container is scales responsively, while container-fluid is always width:100%. Therefore in the root CSS definitions, they appear the same, but if you look further you'll see that .container is bound to media queries.

Bootstrap 4

The container has 5 widths...

.container {
  width: 100%;
}

@media (min-width: 576px) {
  .container {
    max-width: 540px;
  }
}

@media (min-width: 768px) {
  .container {
    max-width: 720px;
  }
}

@media (min-width: 992px) {
  .container {
    max-width: 960px;
  }
}

@media (min-width: 1200px) {
  .container {
    max-width: 1140px;
  }
}

Bootstrap 3

The container has 4 sizes. Full width on xs screens, and then it's width varies based on the following media queries..

    @media (min-width: 1200px) {
        .container {
            width: 1170px;
        }
    }
    @media (min-width: 992px) {
        .container {
            width: 970px;
        }
    }
    @media (min-width: 768px) {
        .container {
            width: 750px;
        }
    }

container vs. container-fluid demo

Use __time function:

• ${__time(dd/MM/yyyy,)}

• ${__time(hh:mm a,)}

Since JMeter 3.3, there are two new functions that let you compute a time:

__timeShift

  "The timeShift function returns a date in the given format with the specified amount of seconds, minutes, hours, days or months added" and 

__RandomDate

  "The RandomDate function returns a random date that lies between the given start date and end date values." 

Since JMeter 4.0:

dateTimeConvert

Convert a date or time from source to target format

If you're looking to learn jmeter correctly, this book will help you.

Start with this:

Set fso = CreateObject("Scripting.FileSystemObject")
If (fso.FileExists(path)) Then
   msg = path & " exists."
Else
   msg = path & " doesn't exist."
End If

Taken from the documentation.

You have to escape the backslash, so try this:

str = "Hello\\nWorld";

Here are more escaped characters in Javascript.

You have to manage client session on the client side. This means that you have to send authentication data with every request, and you probably, but not necessary have an in-memory cache on the server, which pairs auth data to user information like identity, permissions, etc...

This REST statelessness constraint is very important. Without applying this constraint, your server side application won't scale well, because maintaining every single client session will be its Achilles' heel.

var array = string.split(',');

MDN reference, mostly helpful for the possibly unexpected behavior of the limit parameter. (Hint: "a,b,c".split(",", 2) comes out to ["a", "b"], not ["a", "b,c"].)

Yes, this can be scripted with VBScript. For example the following code can create a zip from a directory:

Dim fso, winShell, MyTarget, MySource, file
Set fso = CreateObject("Scripting.FileSystemObject")
Set winShell = createObject("shell.application")


MyTarget = Wscript.Arguments.Item(0)
MySource = Wscript.Arguments.Item(1)

Wscript.Echo "Adding " & MySource & " to " & MyTarget

'create a new clean zip archive
Set file = fso.CreateTextFile(MyTarget, True)
file.write("PK" & chr(5) & chr(6) & string(18,chr(0)))
file.close

winShell.NameSpace(MyTarget).CopyHere winShell.NameSpace(MySource).Items

do until winShell.namespace(MyTarget).items.count = winShell.namespace(MySource).items.count
    wscript.sleep 1000 
loop

Set winShell = Nothing
Set fso = Nothing

You may also find http://www.naterice.com/blog/template_permalink.asp?id=64 helpful as it includes a full Unzip/Zip implementation in VBScript.

If you do a size check every 500 ms rather than a item count it works better for large files. Win 7 writes the file instantly although it's not finished compressing:

set fso=createobject("scripting.filesystemobject")
Set h=fso.getFile(DestZip)
do
    wscript.sleep 500
    max = h.size
loop while h.size > max 

Works great for huge amounts of log files.

This works for me, I only need first numbers in string:

TO_NUMBER(regexp_substr(h.HIST_OBSE, '\.*[[:digit:]]+\.*[[:digit:]]*'))

the field had the following string: "(43 Paginas) REGLAS DE PARTICIPACION".

result field: 43

Try to concatenate the event charCode to the value you get. Here is a sample of my code:

<input type="text" name="price" onkeypress="return (cnum(event,this))" maxlength="10">
<p id="demo"></p>

js:

function cnum(event, str) {
    var a = event.charCode;
    var ab = str.value + String.fromCharCode(a);
    document.getElementById('demo').innerHTML = ab;
}

The value in ab will get the latest value in the input field.

here is my In Place implementation in C

void rotateRight(int matrix[][SIZE], int length) {

    int layer = 0;

    for (int layer = 0; layer < length / 2; ++layer) {

        int first = layer;
        int last = length - 1 - layer;

        for (int i = first; i < last; ++i) {

            int topline = matrix[first][i];
            int rightcol = matrix[i][last];
            int bottomline = matrix[last][length - layer - 1 - i];
            int leftcol = matrix[length - layer - 1 - i][first];

            matrix[first][i] = leftcol;
            matrix[i][last] = topline;
            matrix[last][length - layer - 1 - i] = rightcol;
            matrix[length - layer - 1 - i][first] = bottomline;
        }
    }
}

Please see if following solution works for you. The trick is to define a base processor interface which takes a base type of message.

interface IMessage
{
}

class LoginMessage : IMessage
{
}

class LogoutMessage : IMessage
{
}

class UnknownMessage : IMessage
{
}

interface IMessageProcessor
{
    void PrcessMessageBase(IMessage msg);
}

abstract class MessageProcessor<T> : IMessageProcessor where T : IMessage
{
    public void PrcessMessageBase(IMessage msg)
    {
        ProcessMessage((T)msg);
    }

    public abstract void ProcessMessage(T msg);

}

class LoginMessageProcessor : MessageProcessor<LoginMessage>
{
    public override void ProcessMessage(LoginMessage msg)
    {
        System.Console.WriteLine("Handled by LoginMsgProcessor");
    }
}

class LogoutMessageProcessor : MessageProcessor<LogoutMessage>
{
    public override void ProcessMessage(LogoutMessage msg)
    {
        System.Console.WriteLine("Handled by LogoutMsgProcessor");
    }
}

class MessageProcessorTest
{
    /// <summary>
    /// IMessage Type and the IMessageProcessor which would process that type.
    /// It can be further optimized by keeping IMessage type hashcode
    /// </summary>
    private Dictionary<Type, IMessageProcessor> msgProcessors = 
                                new Dictionary<Type, IMessageProcessor>();
    bool processorsLoaded = false;

    public void EnsureProcessorsLoaded()
    {
        if(!processorsLoaded)
        {
            var processors =
                from processorType in Assembly.GetExecutingAssembly().GetTypes()
                where processorType.IsClass && !processorType.IsAbstract &&
                      processorType.GetInterface(typeof(IMessageProcessor).Name) != null
                select Activator.CreateInstance(processorType);

            foreach (IMessageProcessor msgProcessor in processors)
            {
                MethodInfo processMethod = msgProcessor.GetType().GetMethod("ProcessMessage");
                msgProcessors.Add(processMethod.GetParameters()[0].ParameterType, msgProcessor);
            }

            processorsLoaded = true;
        }
    }

    public void ProcessMessages()
    {
        List<IMessage> msgList = new List<IMessage>();
        msgList.Add(new LoginMessage());
        msgList.Add(new LogoutMessage());
        msgList.Add(new UnknownMessage());

        foreach (IMessage msg in msgList)
        {
            ProcessMessage(msg);
        }
    }

    public void ProcessMessage(IMessage msg)
    {
        EnsureProcessorsLoaded();
        IMessageProcessor msgProcessor = null;
        if(msgProcessors.TryGetValue(msg.GetType(), out msgProcessor))
        {
            msgProcessor.PrcessMessageBase(msg);
        }
        else
        {
            System.Console.WriteLine("Processor not found");
        }
    }

    public static void Test()
    {
        new MessageProcessorTest().ProcessMessages();
    }
}

Thanx to @androidbloke,
I have added some library that I know for multiple image picker in swift.
Will update list as I find new ones.
Thank You.

partition() may be better then split() for this purpose as it has the better predicable results for situations you have no delimiter or more delimiters.

I used the Debug "app" button
and my problem was solved

You could just use index on the list to find where somevalue is and then get the previous and next as needed:

def find_prev_next(elem, elements):
    previous, next = None, None
    index = elements.index(elem)
    if index > 0:
        previous = elements[index -1]
    if index < (len(elements)-1):
        next = elements[index +1]
    return previous, next


foo = 'three'
list = ['one','two','three', 'four', 'five']

previous, next = find_prev_next(foo, list)

print previous # should print 'two'
print next # should print 'four'

The iPhone SDK agreement is also rather vague about whether you're even allowed to run scripting languages (outside of a WebView's Javascript). My reading is that it is OK - as long as none of the scripts you execute are downloaded from the network (so pre-installed and user-edited scripts seem to be OK).

IANAL etc etc.

If you want to have access to the id attribute of the button in angular 6 follow this code

`@Component({
  selector: 'my-app',
  template: `
    <button (click)="clicked($event)" id="myId">Click Me</button>
  `
})
export class AppComponent {
  clicked(event) {
    const target = event.target || event.srcElement || event.currentTarget;
    const idAttr = target.attributes.id;
    const value = idAttr.nodeValue;
  }
}`

your id in the value,

the value of value is myId.

Presumably, since you're not providing a value for the DB_ID column, that value is being populated by a row-level before insert trigger defined on the table. That trigger, presumably, is selecting the value from a sequence.

Since the data was moved (presumably recently) from the production database, my wager would be that when the data was copied, the sequence was not modified as well. I would guess that the sequence is generating values that are much lower than the largest DB_ID that is currently in the table leading to the error.

You could confirm this suspicion by looking at the trigger to determine which sequence is being used and doing a

SELECT <<sequence name>>.nextval
  FROM dual

and comparing that to

SELECT MAX(db_id)
  FROM cmdb_db

If, as I suspect, the sequence is generating values that already exist in the database, you could increment the sequence until it was generating unused values or you could alter it to set the INCREMENT to something very large, get the nextval once, and set the INCREMENT back to 1.

This should work. I would trim the whitespace from the input field first of all:

if($('#Field').val() != "") {
    var value = $('#Field').val().replace(/^\s\s*/, '').replace(/\s\s*$/, '');
    var intRegex = /^\d+$/;
    if(!intRegex.test(value)) {
        errors += "Field must be numeric.<br/>";
        success = false;
    }
} else {
    errors += "Field is blank.</br />";
    success = false;
}

If you don't want to reference Forms you can use interop to get the cursor position:

using System.Runtime.InteropServices;
using System.Windows; // Or use whatever point class you like for the implicit cast operator

/// <summary>
/// Struct representing a point.
/// </summary>
[StructLayout(LayoutKind.Sequential)]
public struct POINT
{
    public int X;
    public int Y;

    public static implicit operator Point(POINT point)
    {
        return new Point(point.X, point.Y);
    }
}

/// <summary>
/// Retrieves the cursor's position, in screen coordinates.
/// </summary>
/// <see>See MSDN documentation for further information.</see>
[DllImport("user32.dll")]
public static extern bool GetCursorPos(out POINT lpPoint);

public static Point GetCursorPosition()
{
    POINT lpPoint;
    GetCursorPos(out lpPoint);
    // NOTE: If you need error handling
    // bool success = GetCursorPos(out lpPoint);
    // if (!success)
        
    return lpPoint;
}

You could try using a Bloom Filter. Insert each number in the bag into the bloom, then iterate over the complete 1-k set until reporting each one not found. This may not find the answer in all scenarios, but might be a good enough solution.

It works for me to check single quote in Prettier as well tslint.autoFixOnSave as true

I would write GetValue as below

public static T GetValue<T>(this JToken jToken, string key, T defaultValue = default(T))
{
    dynamic ret = jToken[key];
    if (ret == null) return defaultValue;
    if (ret is JObject) return JsonConvert.DeserializeObject<T>(ret.ToString());
    return (T)ret;
}

This way you can get the value of not only the basic types but also complex objects. Here is a sample

public class ClassA
{
    public int I;
    public double D;
    public ClassB ClassB;
}
public class ClassB
{
    public int I;
    public string S;
}

var jt = JToken.Parse("{ I:1, D:3.5, ClassB:{I:2, S:'test'} }");

int i1 = jt.GetValue<int>("I");
double d1 = jt.GetValue<double>("D");
ClassB b = jt.GetValue<ClassB>("ClassB");

To run your app on a real device, you need to have an Apple ID, and have registered your device with that ID. That is why you are getting this error.

Here's how you do it.

1. Go to the project Navigator. Cmd-1 if you can't find it.

2. Click the project target dropdown and pick Target.

3. Click on the Team dropdown and pick add an account.

4. Sign in with your Apple ID that is linked to your developer account, or just your Apple if you don't have a dev account.

5. If you haven't registered your device with that account yet, a button will appear, something like 'Register device'. Click that and Apple will register the device and do the certificates and code signing. (Oh my unicorns certificates and signing is so much easier than it used to be)

Pick your physical device and hit run and it should load onto your device without error.

exec 'print "hello";' * 2

should work, but I'm kind of ashamed that I thought of it.

Update: Just thought of another one:

for _ in " "*10: print "hello"

None of these answers was satisfactory for my situation. I'm on subversion 1.8 and I had a working copy that only had a single .svn folder at the very first folder, root. However, I wanted to remove some branches from working copy.

No matter what I did, whenever I ran an 'update' it would restore those files and bring them all back. I didn't want to remove them from the repository, just from my computer -- but I needed to keep the rest of the working copy in tact (thus couldn't just remove the .svn folder).

Solution? svn update --set-depth exclude <dir>

This is a client-side "update" that excludes a specific directory. It can be found in the manuals at svnbook.com. In short, it describes this as:

Beginning with Subversion 1.6, you can take a different approach. First, check out the directory in full. Then run svn update --set-depth exclude on the one subdirectory you don't care about.

For TortoiseSVN, you can also do the same thing by right-clicking the folder you don't want, click on Update to revision..., and then set the 'Update Depth' to Exclude, as seen in this screen shot:

This worked for me...

    double num = 10025000;
    new DecimalFormat("#,###.##");
    DecimalFormat df = (DecimalFormat) DecimalFormat.getInstance(Locale.GERMAN);
    System.out.println(df.format(num));

Since Java 11 you can do:

FileWriter fw = new FileWriter("filename.txt", Charset.forName("utf-8"));

For any Solaris users (am using 5.10, may apply to newer versions too, as well as other unix systems):

dos2unix doesn't default to overwriting the file, it will just print the updated version to stdout, so you will have to specify the source and target, i.e. the same name twice:

find . -type f -exec dos2unix {} {} \;

The "normal" way is to:

• Go to the Beautiful Soup web site, http://www.crummy.com/software/BeautifulSoup/
• Download the package
• Unpack it
• In a Terminal window, cd to the resulting directory
• Type python setup.py install

Another solution is to use easy_install. Go to http://peak.telecommunity.com/DevCenter/EasyInstall), install the package using the instructions on that page, and then type, in a Terminal window:

easy_install BeautifulSoup4
# for older v3:
# easy_install BeautifulSoup

easy_install will take care of downloading, unpacking, building, and installing the package. The advantage to using easy_install is that it knows how to search for many different Python packages, because it queries the PyPI registry. Thus, once you have easy_install on your machine, you install many, many different third-party packages simply by one command at a shell.

If you don't wish to compile bootstrap, copy the following and insert it in your custom css file. It's not recommended to change the original bootstrap css file. Also, you won't be able to modify the bootstrap original css if you are loading it from a cdn.

Paste this in your custom css file:

@media (min-width:992px)
    {
        .container{width:960px}
    }
@media (min-width:1200px)
    {
        .container{width:960px}
    }

I am here setting my container to 960px for anything that can accommodate it, and keeping the rest media sizes to default values. You can set it to 940px for this problem.

ax.axis('off'), will as Joe Kington pointed out, remove everything except the plotted line.

For those wanting to only remove the frame (border), and keep labels, tickers etc, one can do that by accessing the spines object on the axis. Given an axis object ax, the following should remove borders on all four sides:

ax.spines['top'].set_visible(False)
ax.spines['right'].set_visible(False)
ax.spines['bottom'].set_visible(False)
ax.spines['left'].set_visible(False)

And, in case of removing x and y ticks from the plot:

 ax.get_xaxis().set_ticks([])
 ax.get_yaxis().set_ticks([])

You cannot store arrays in a vector or any other container. The type of the elements to be stored in a container (called the container's value type) must be both copy constructible and assignable. Arrays are neither.

You can, however, use an array class template, like the one provided by Boost, TR1, and C++0x:

std::vector<std::array<double, 4> >

(You'll want to replace std::array with std::tr1::array to use the template included in C++ TR1, or boost::array to use the template from the Boost libraries. Alternatively, you can write your own; it's quite straightforward.)

Above answers are helpful, I'd just like to add an example that I think is demonstrating clearly what happens when we pass parameter without the ref keyword, even when that parameter is a reference type:

MyClass c = new MyClass(); c.MyProperty = "foo";

CNull(c); // only a copy of the reference is sent 
Console.WriteLine(c.MyProperty); // still foo, we only made the copy null
CPropertyChange(c); 
Console.WriteLine(c.MyProperty); // bar


private void CNull(MyClass c2)
        {          
            c2 = null;
        }
private void CPropertyChange(MyClass c2) 
        {
            c2.MyProperty = "bar"; // c2 is a copy, but it refers to the same object that c does (on heap) and modified property would appear on c.MyProperty as well.
        }

The Math.round method returns a long (or an int if you pass in a float), and Java's integer division is the culprit. Cast it back to a double, or use a double literal when dividing by 10. Either:

double total = (double) Math.round((num / sum * 100) * 10) / 10;

or

double total = Math.round((num / sum * 100) * 10) / 10.0;

Then you should get

27.3

  $original_str="this . is . to . find";
  echo "<br/> Position: ". $pos=strrpos($original_str, ".");
  $len=strlen($original_str);
  if($pos >= 0)
  {
    echo "<br/> Extension: ".   substr($original_str,$pos+1,$len-$pos) ;
   } 

You can use a replace regular expression.

s/[;,\t\r ]|[\n]{2}/\n/g

• s/ at the beginning means a search
• The characters between [ and ] are the characters to search for (in any order)
• The second / delimits the search-for text and the replace text

In English, this reads:

"Search for ; or , or \t or \r or (space) or exactly two sequential \n and replace it with \n"

In C#, you could do the following: (after importing System.Text.RegularExpressions)

Regex pattern = new Regex("[;,\t\r ]|[\n]{2}");
pattern.Replace(myString, "\n");

In my memory, excel (versions >= 2007) limits the power 2 of 20: 1.048.576 lines.

Csv is over to this boundary, like ordinary text file. So you will be care of the transfer between two formats.

color="white" is not a known attribute to Angular Material.

color attribute can changed to primary, accent, and warn. as said in this doc

your icon inside button works because its parent class button has css class of color:white, or may be your color="accent" is white. check the developer tools to find it.

By default, icons will use the current font color

As per the latest bootstrap v3.3.7 xs-offseting is allowed. See the documentation here bootstrap offseting. So you can use

<div class="col-xs-2 col-xs-offset-1">.col-xs-2 .col-xs-offset-1</div>

radian can also be converted to degree by using numpy

print(np.rad2deg(1))
57.29577951308232

if needed to roundoff ( I did with 6 digits after decimal below), then

print(np.round(np.rad2deg(1), 6)

57.29578

Check if you actually have installed the buildVersionTools you are using. In my case I tried 25.0.1 whilst I only had 25.0.2.

To check it go to the SDK Manager, clicking the icon:

Then click Launch Standalone SDK Manager at the bottom:

Now check whatever you need and install packages.

It is possible. You can have the download started from inside an ajax function, for example, just after the .csv file is created.

I have an ajax function that exports a database of contacts to a .csv file, and just after it finishes, it automatically starts the .csv file download. So, after I get the responseText and everything is Ok, I redirect browser like this:

window.location="download.php?filename=export.csv";

My download.php file looks like this:

<?php

    $file = $_GET['filename'];

    header("Cache-Control: public");
    header("Content-Description: File Transfer");
    header("Content-Disposition: attachment; filename=".$file."");
    header("Content-Transfer-Encoding: binary");
    header("Content-Type: binary/octet-stream");
    readfile($file);

?>

There is no page refresh whatsoever and the file automatically starts downloading.

NOTE - Tested in the following browsers:

Chrome v37.0.2062.120 
Firefox v32.0.1
Opera v12.17
Internet Explorer v11

You could remove the name attribute of this input, so it won't be submited.

To access the value of this controll:

$("div#someID").datepicker( "getDate" )

and your may have a look at the document in http://jqueryui.com/demos/datepicker/

The properties on the style object are only the styles applied directly to the element (e.g., via a style attribute or in code). So .style.marginTop will only have something in it if you have something specifically assigned to that element (not assigned via a style sheet, etc.).

To get the current calculated style of the object, you use either the currentStyle property (Microsoft) or the getComputedStyle function (pretty much everyone else).

Example:

var p = document.getElementById("target");
var style = p.currentStyle || window.getComputedStyle(p);

display("Current marginTop: " + style.marginTop);

Fair warning: What you get back may not be in pixels. For instance, if I run the above on a p element in IE9, I get back "1em".

There were several problems in your code. Here you have a functional version you can analyze (Lets set 'hello' as the target word):

word = 'hello'
so_far = "-" * len(word)       # Create variable so_far to contain the current guess

while word != so_far:          # if still not complete
    print(so_far)
    guess = input('>> ')       # get a char guess

    if guess in word:
        print("\nYes!", guess, "is in the word!")

        new = ""
        for i in range(len(word)):  
            if guess == word[i]:
                new += guess        # fill the position with new value
            else:
                new += so_far[i]    # same value as before
        so_far = new
    else:
        print("try_again")

print('finish')

I tried to write it for py3k with a py2k ide, be careful with errors.

Another way to do it in the for loop

void rm_nl(string &s) {
    for (int p = s.find("\n"); p != (int) string::npos; p = s.find("\n"))
    s.erase(p,1);
}

Usage:

string data = "\naaa\nbbb\nccc\nddd\n";
rm_nl(data); 
cout << data; // data = aaabbbcccddd

Senguttuvan: your solution was the only thing that worked for me.

Unfortunately, the best thing I have seen is the jquery.combobox, but it doesn't really look like something I'd really want to use in my web applications. I think there are some usability issues with this control, but as a user I don't think I'd know to start typing for the dropdownlist to turn into a textbox.

I much prefer the Combo Dropdown Box, but it still has some features that I'd want and it's still in alpha. The only think I don't like about this other than its being alpha... is that once I type in the combobox, the original dropdownlist items disappear. However, maybe there is a setting for this... or maybe it could be added fairly easily.

Those are the only two options that I know of. Good luck in your search. I'd love to hear if you find one or if the second option works out for you.

Okay I just realized the answer is to remove the first float left from the first DIV. Don't know why I didn't see that before.

enum types are called "enumeration types" not because they are containers that "enumerate" values (which they aren't), but because they are defined by enumerating the possible values for a variable of that type.

(Actually, that's a bit more complicated than that - enum types are considered to have an "underlying" integer type, which means each enum value corresponds to an integer value (this is typically implicit, but can be manually specified). C# was designed in a way so that you could stuff any integer of that type into the enum variable, even if it isn't a "named" value.)

The System.Enum.GetNames method can be used to retrieve an array of strings which are the names of the enum values, as the name suggests.

EDIT: Should have suggested the System.Enum.GetValues method instead. Oops.

   optionsFG: FormGroup;
   this.optionsFG = this.fb.group({
       optionValue: [null, Validators.required]

HTML

   <div class="text-right" [formGroup]="optionsFG">
     <mat-form-field>
         <mat-select placeholder="Category" formControlName="optionValue">
           <mat-option *ngFor="let option of options;let i =index" [value]="option">
            {{option.Value}}
          </mat-option>
        </mat-select>
      </mat-form-field>
  </div>

Use explicit injection. No other approach will allow you for instance to run tests in parallel in the same JVM.

Patterns that use anything classloader wide like static log binder or messing with environmental thinks like logback.XML are bust when it comes to testing.

Consider the parallelized tests I mention , or consider the case where you want to intercept logging of component A whose construction is hidden behind api B. This latter case is easy to deal with if you are using a dependency injected loggerfactory from the top, but not if you inject Logger as there no seam in this assembly at ILoggerFactory.getLogger.

And its not all about unit testing either. Sometimes we want integration tests to emit logging. Sometimes we don't. Someone's we want some of the integration testing logging to be selectively suppressed, eg for expected errors that would otherwise clutter the CI console and confuse. All easy if you inject ILoggerFactory from the top of your mainline (or whatever di framework you might use)

So...

Either inject a reporter as suggested or adopt a pattern of injecting the ILoggerFactory. By explicit ILoggerFactory injection rather than Logger you can support many access/intercept patterns and parallelization.

[function.fopen]: failed to open stream

If you have access to your php.ini file, try enabling Fopen. Find the respective line and set it to be "on": & if in wp e.g localhost/wordpress/function.fopen in the php.ini :

allow_url_fopen = off
should bee this 
allow_url_fopen = On

And add this line below it:
allow_url_include = off
should bee this 
allow_url_include = on

Follow the path /etc/php5(your php version)/apache2/php.ini.

Open it and set the value of max_execution_time to a desired one.

If you're concerned about server performance then look at capping the number of running sox processes. If the cap has been hit you can always cache the request and inform the user when it's finished in whichever way suits your application.

Alternatively, have the n worker scripts on other machines that pull requests from the db and call sox, and then push the resulting output file to where it needs to be.

Note that %in% returns a logical vector of TRUE and FALSE. To negate it, you can use ! in front of the logical statement:

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
 !where_case_travelled_1 %in% 
   c('Outside Canada','Outside province/territory of residence but within Canada'))

Regarding your original approach with -c(...), - is a unary operator that "performs arithmetic on numeric or complex vectors (or objects which can be coerced to them)" (from help("-")). Since you are dealing with a character vector that cannot be coerced to numeric or complex, you cannot use -.

This is what I use in my application:

static void Main()
{
  bool mutexCreated = false;
  System.Threading.Mutex mutex = new System.Threading.Mutex( true, @"Local\slimCODE.slimKEYS.exe", out mutexCreated );

  if( !mutexCreated )
  {
    if( MessageBox.Show(
      "slimKEYS is already running. Hotkeys cannot be shared between different instances. Are you sure you wish to run this second instance?",
      "slimKEYS already running",
      MessageBoxButtons.YesNo,
      MessageBoxIcon.Question ) != DialogResult.Yes )
    {
      mutex.Close();
      return;
    }
  }

  // The usual stuff with Application.Run()

  mutex.Close();
}

If you really need then you can use i.e.   entity to do that, but remember that fonts used to render your page are usually proportional, so "aligning" with spaces does not really work and looks ugly.

Additionally, you can change the keys view window -> preferences then type: 'keys' and when the key preference page opens you can type 'toggle block selection' and voila!

Ctrl-/ will insert // style commenting, for javascript, etc
Ctrl-/ will insert <!-- --> comments for HTML,
Ctrl-/ will insert # comments for Ruby,

But does not work perfectly on HTML <script> tags.

HTML <script> ..blah.. </script> tags:
Ctrl-/ twice (ie Ctrl-/Ctrl-/) will effectively comment out the line:

• The first Ctrl-/ adds // to the beginning of the line,
  which comments out the script tag, but adds "//" text to your webpage.
• The second Ctrl-/ then surrounds that in <!-- --> style comments, which accomplishes the task.

Ctrl--Shift-/ does not produce multi-line comments on HTML (or even single line comments), but does
add /* */ style multi-line comments in Javascript, text, and other file formats.

I included this info because this is the info I was looking for, and this is the only related StackOverflow page from my search results.

Short Answer

If the goal is to create a grid with equal height rows, where the tallest cell in the grid sets the height for all rows, here's a quick and simple solution:

• Set the container to grid-auto-rows: 1fr

How it works

Grid Layout provides a unit for establishing flexible lengths in a grid container. This is the fr unit. It is designed to distribute free space in the container and is somewhat analogous to the flex-grow property in flexbox.

If you set all rows in a grid container to 1fr, let's say like this:

grid-auto-rows: 1fr;

... then all rows will be equal height.

It doesn't really make sense off-the-bat because fr is supposed to distribute free space. And if several rows have content with different heights, then when the space is distributed, some rows would be proportionally smaller and taller.

Except, buried deep in the grid spec is this little nugget:

7.2.3. Flexible Lengths: the fr unit

...

When the available space is infinite (which happens when the grid container’s width or height is indefinite), flex-sized (fr) grid tracks are sized to their contents while retaining their respective proportions.

The used size of each flex-sized grid track is computed by determining the max-content size of each flex-sized grid track and dividing that size by the respective flex factor to determine a “hypothetical 1fr size”.

The maximum of those is used as the resolved 1fr length (the flex fraction), which is then multiplied by each grid track’s flex factor to determine its final size.

So, if I'm reading this correctly, when dealing with a dynamically-sized grid (e.g., the height is indefinite), grid tracks (rows, in this case) are sized to their contents.

The height of each row is determined by the tallest (max-content) grid item.

The maximum height of those rows becomes the length of 1fr.

That's how 1fr creates equal height rows in a grid container.

Why flexbox isn't an option

As noted in the question, equal height rows are not possible with flexbox.

Flex items can be equal height on the same row, but not across multiple rows.

This behavior is defined in the flexbox spec:

6. Flex Lines

In a multi-line flex container, the cross size of each line is the minimum size necessary to contain the flex items on the line.

In other words, when there are multiple lines in a row-based flex container, the height of each line (the "cross size") is the minimum height necessary to contain the flex items on the line.

Without reading your code but just your scenario, I would solve by using localStorage. Here's an example, I'll use prompt() for short.

On page1:

window.onload = function() {
   var getInput = prompt("Hey type something here: ");
   localStorage.setItem("storageName",getInput);
}

On page2:

window.onload = alert(localStorage.getItem("storageName"));

You can also use cookies but localStorage allows much more spaces, and they aren't sent back to servers when you request pages.

git log -n 1 [branch_name]

branch_name (may be remote or local branch) is optional. Without branch_name, it will show the latest commit on the current branch.

For example:

git log -n 1
git log -n 1 origin/master
git log -n 1 some_local_branch

git log -n 1 --pretty=format:"%H"  #To get only hash value of commit

float is the closest equivalent.

SqlDbType Enumeration

For Lat/Long as OP mentioned.

A metre is 1/40,000,000 of the latitude, 1 second is around 30 metres. Float/double give you 15 significant figures. With some quick and dodgy mental arithmetic... the rounding/approximation errors would be the about the length of this fill stop -> "."

Add this to webpack.config.js:

devServer: {
    historyApiFallback: true
}

There is also a compact form for that, if you do not want to rely on strlen. Assuming that the character array you are considering is "msg":

  unsigned int len=0;
  while(*(msg+len) ) len++;

You can add or increase the day of week for the following example and hope this will helpful for you.Lets see....

        //Current date
        var currentDate = new Date();
        //to set Bangladeshi date need to add hour 6           

        currentDate.setUTCHours(6);            
        //here 2 is day increament for the date and you can use -2 for decreament day
        currentDate.setDate(currentDate.getDate() +parseInt(2));

        //formatting date by mm/dd/yyyy
        var dateInmmddyyyy = currentDate.getMonth() + 1 + '/' + currentDate.getDate() + '/' + currentDate.getFullYear();           

What you could do is use ng-repeat passing in the value of whatever you're iterating on to the ng-checked and from there utilising ng-class to apply your styles depending on the result.

I did something similar recently and it worked for me.

Solutions that did not work

No: The - create a shortcut [ -> Compatibility -> "run this program as an administrator" ] solution does not work.

This option is greyed out in Windows 7. Even with UAC disabled

No: The runas /env /user:domain\Administrator <program.exe/command you want to execute> is also not sufficient because it will prompt the user for the admin password.

Solution that worked

Yes: Disable UAC -> Create a job using task scheduler, this worked for me.

• Create a job under task scheduler and make it run as a user with administrator permissions.
• Explicitly mark: "Run with highest privileges"
• Disable UAC so there will be no prompt to run this task

You can let the script enable UAC afterwards by editing the registry if you would want. In my case this script is ran only once by creation of a windows virtual machine, where UAC is disabled in the image.

Still looking forward for the best approach for a script run as admin without too much hassle.

You can also do:

alist.pop()

It depends on what you want to do with your list because the pop() method will delete the last element.

Yet another non-bash-4 (i.e., bash 3, Mac-compatible) way:

val_of_key() {
    case $1 in
        'A1') echo 'aaa';;
        'B2') echo 'bbb';;
        'C3') echo 'ccc';;
        *) echo 'zzz';;
    esac
}

for x in 'A1' 'B2' 'C3' 'D4'; do
    y=$(val_of_key "$x")
    echo "$x => $y"
done

Prints:

A1 => aaa
B2 => bbb
C3 => ccc
D4 => zzz

The function with the case acts like an associative array. Unfortunately it cannot use return, so it has to echo its output, but this is not a problem, unless you are a purist that shuns forking subshells.

I started using the 'prefix-free' Script available at http://leaverou.github.io/prefixfree so I don't have to take care about the vendor prefixes. It neatly takes care of setting the correct vendor prefix behind the scenes for you. Plus a jQuery Plugin is available as well so one can still use jQuery's .css() method without code changes, so the suggested line in combination with prefix-free would be all you need:

$('.user-text').css('transform', 'scale(' + ui.value + ')');

This is called the "shape" in NumPy, and can be requested via the .shape attribute:

>>> a = zeros((2, 5))
>>> a.shape
(2, 5)

If you prefer a function, you could also use numpy.shape(a).

There is no best way, it depends on your use case.

• Use way 1 if you want to create several similar objects. In your example, Person (you should start the name with a capital letter) is called the constructor function. This is similar to classes in other OO languages.
• Use way 2 if you only need one object of a kind (like a singleton). If you want this object to inherit from another one, then you have to use a constructor function though.
• Use way 3 if you want to initialize properties of the object depending on other properties of it or if you have dynamic property names.

Update: As requested examples for the third way.

Dependent properties:

The following does not work as this does not refer to book. There is no way to initialize a property with values of other properties in a object literal:

var book = {
    price: somePrice * discount,
    pages: 500,
    pricePerPage: this.price / this.pages
};

instead, you could do:

var book = {
    price: somePrice * discount,
    pages: 500
};
book.pricePerPage = book.price / book.pages;
// or book['pricePerPage'] = book.price / book.pages;

Dynamic property names:

If the property name is stored in some variable or created through some expression, then you have to use bracket notation:

var name = 'propertyName';

// the property will be `name`, not `propertyName`
var obj = {
    name: 42
}; 

// same here
obj.name = 42;

// this works, it will set `propertyName`
obj[name] = 42;

This worked for me like a charm for downloading PNG and PDF.

PostgreSQL DLL to add an FK column:

ALTER TABLE one
ADD two_id INTEGER REFERENCES two;

I found that a combination of the other answers works:

interface ApiInterface {
    @GET("/someurl")
    Call<ResponseBody> getdata()
}

apiService.getdata().enqueue(object : Callback {
    override fun onResponse(call: Call, response: Response) {
        val rawJsonString = response.body()?.string()
    }
})

The important part are that the response type should be ResponseBody and use response.body()?.string() to get the raw string.

robocopy c:\logs\SoManyDirectoriesToDelete\ c:\temp\OldDirectoriesGoHere\ /move /minage:7
rmdir /s /q c:\temp\OldDirectoriesGoHere

Here's another dodge that I came up with for my base repository class where I needed to order by an arbitrary number of columns:

public function findAll(array $where = [], array $with = [], array $orderBy = [], int $limit = 10)
{
    $result = $this->model->with($with);
    $dataSet = $result->where($where)
        // Conditionally use $orderBy if not empty
        ->when(!empty($orderBy), function ($query) use ($orderBy) {
            // Break $orderBy into pairs
            $pairs = array_chunk($orderBy, 2);
            // Iterate over the pairs
            foreach ($pairs as $pair) {
                // Use the 'splat' to turn the pair into two arguments
                $query->orderBy(...$pair);
            }
        })
        ->paginate($limit)
        ->appends(Input::except('page'));

    return $dataSet;
}

Now, you can make your call like this:

$allUsers = $userRepository->findAll([], [], ['name', 'DESC', 'email', 'ASC'], 100);

@Balamanigandan your Original Post :- PHP Notice: Trying to get property of non-object error

Your are trying to access the Null Object. From AngularJS your are not passing any Objects instead you are passing the $_GET element. Try by using $_GET['uid'] instead of $objData->token

For one-dimensional arrays:

$array = (array)$class; 

For multi-dimensional array:

function stdToArray($obj){
  $reaged = (array)$obj;
  foreach($reaged as $key => &$field){
    if(is_object($field))$field = stdToArray($field);
  }
  return $reaged;
}

Use strpos():

if (strpos($string2, 'http') === 0) {
   // It starts with 'http'
}

Remember the three equals signs (===). It will not work properly if you only use two. This is because strpos() will return false if the needle cannot be found in the haystack.

Two issues:

1. You're passing the jQuery wrapper of the element into parseInt, which isn't what you want, as parseInt will call toString on it and get back "[object Object]". You need to use val or text or something (depending on what the element is) to get the string you want.

2. You're not telling parseInt what radix (number base) it should use, which puts you at risk of odd input giving you odd results when parseInt guesses which radix to use.

Fix if the element is a form field:

//                               vvvvv-- use val to get the value
var test = parseInt($("#testid").val(), 10);
//                                    ^^^^-- tell parseInt to use decimal (base 10)

Fix if the element is something else and you want to use the text within it:

//                               vvvvvv-- use text to get the text
var test = parseInt($("#testid").text(), 10);
//                                     ^^^^-- tell parseInt to use decimal (base 10)

Try the code below. e.preventDefault() was added. This removes the default event action for the form.

 $(document).ready(function () {
    $("form").submit(function (e) {
       $.ajax({
            url: '@Url.Action("HasJobInProgress", "ClientChoices")/',
            data: { id: '@Model.ClientId' },
            success: function (data) {
                showMsg(data, e);
            },
            cache: false
        });
        e.preventDefault();
    });
});

Also, you mentioned you wanted the form to not submit under the premise of validation, but I see no code validation here?

Here is an example of some added validation

 $(document).ready(function () {
    $("form").submit(function (e) {
      /* put your form field(s) you want to validate here, this checks if your input field of choice is blank */
    if(!$('#inputID').val()){ 
       e.preventDefault(); // This will prevent the form submission
     } else{
        // In the event all validations pass. THEN process AJAX request.
       $.ajax({
            url: '@Url.Action("HasJobInProgress", "ClientChoices")/',
            data: { id: '@Model.ClientId' },
            success: function (data) {
                showMsg(data, e);
            },
            cache: false
       });
     }


    });
 });

Simple example based off of @Tuan Zaidi's example above which seemed the easiest. Didn't know you can do the filter on the outside of OPENQUERY... so much easier!

However in my case I needed to stuff it in a variable so I created an additional Sub Query Level to return a single value.

SET @SFID = (SELECT T.Id FROM (SELECT Id,  Contact_ID_SQL__c  FROM OPENQUERY([TR-SF-PROD], 'SELECT Id,  Contact_ID_SQL__c FROM Contact') WHERE Contact_ID_SQL__c = @ContactID) T)

You can create a C# like extension/helper method by (RE) implementing the Collections interface and adding- example for Java Collection:

public class RockCollection<T extends Comparable<T>> implements Collection<T> {
private Collection<T> _list = new ArrayList<T>();

//###########Custom extension methods###########

public T doSomething() {
    //do some stuff
    return _list  
}

//proper examples
public T find(Predicate<T> predicate) {
    return _list.stream()
            .filter(predicate)
            .findFirst()
            .get();
}

public List<T> findAll(Predicate<T> predicate) {
    return _list.stream()
            .filter(predicate)
            .collect(Collectors.<T>toList());
}

public String join(String joiner) {
    StringBuilder aggregate = new StringBuilder("");
    _list.forEach( item ->
        aggregate.append(item.toString() + joiner)
    );
    return aggregate.toString().substring(0, aggregate.length() - 1);
}

public List<T> reverse() {
    List<T> listToReverse = (List<T>)_list;
    Collections.reverse(listToReverse);
    return listToReverse;
}

public List<T> sort(Comparator<T> sortComparer) {
    List<T> listToReverse = (List<T>)_list;
    Collections.sort(listToReverse, sortComparer);
    return listToReverse;
}

public int sum() {
    List<T> list = (List<T>)_list;
    int total = 0;
    for (T aList : list) {
        total += Integer.parseInt(aList.toString());
    }
    return total;
}

public List<T> minus(RockCollection<T> listToMinus) {
    List<T> list = (List<T>)_list;
    int total = 0;
    listToMinus.forEach(list::remove);
    return list;
}

public Double average() {
    List<T> list = (List<T>)_list;
    Double total = 0.0;
    for (T aList : list) {
        total += Double.parseDouble(aList.toString());
    }
    return total / list.size();
}

public T first() {
    return _list.stream().findFirst().get();
            //.collect(Collectors.<T>toList());
}
public T last() {
    List<T> list = (List<T>)_list;
    return list.get(_list.size() - 1);
}
//##############################################
//Re-implement existing methods
@Override
public int size() {
    return _list.size();
}

@Override
public boolean isEmpty() {
    return _list == null || _list.size() == 0;
}

you can do like follows. Remember, IsNull is a function which returns TRUE if the parameter passed to it is null, and false otherwise.

Not IsNull(Fields!W_O_Count.Value)

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

For the GUI minded people, you can:

• Right click the Database in Management Studio.
• Choose Properties
• Select Permissions
• If your user does not show up in the list, choose Search and type their name
• Select the user in the Users or Roles list
• In the lower window frame, Check the Select permission under the Grant column

pg_ctl is a command line (Windows) program not a SQL statement. You need to do that from a cmd.exe. Or use net start postgresql-9.5

If you have installed Postgres through the installer, you should start the Windows service instead of running pg_ctl manually, e.g. using:

net start postgresql-9.5

Note that the name of the service might be different in your installation. Another option is to start the service through the Windows control panel

I have used the pgAdmin II tool to create a database called company

Which means that Postgres is already running, so I don't understand why you think you need to do that again. Especially because the installer typically sets the service to start automatically when Windows is started.

The reason you are not seeing any result is that psql requires every SQL command to be terminated with ; in your case it's simply waiting for you to finish the statement.

See here for more details: In psql, why do some commands have no effect?

This error, as you can read on the question linked in comments above, results to be:

"[...] a problem with loading {some} hardware module. This could be something to do with GPU support, sdcard handling, basically anything."

The step 1 below should resolve this problem. Also as I can see, you have some strange package names inside your manifest:

• package="com.example.hive" in <manifest> tag,
• android:name="com.sit.gems.app.GemsApplication" for <application>
• and android:name="com.sit.gems.activity" in <activity>

As you know, these things do not prevent your app to be displayed. But I think:

the Couldn't load memtrack module error could occur because of emulators configurations problems and, because your project contains many organization problems, it might help to give a fresh redesign.

For better using and with few things, this can be resolved by following these tips:

1. Try an other emulator...

And even a real device! The memtrack module error seems related to your emulator. So change it into Run configuration, don't forget to change the API too.

2. OpenGL error logs

For OpenGl errors, as called unimplemented OpenGL ES API, it's not an error but a statement! You should enable it in your manifest (you can read this answer if you're using GLSurfaceView inside HomeActivity.java, it might help you):

<uses-feature android:glEsVersion="0x00020000"></uses-feature>  
// or
<uses-feature android:glEsVersion="0x00010001" android:required="true" />

3. Use the same package

Don't declare different package names to all the tags in Manifest. You should have the same for Manifest, Activities, etc. Something like this looks right:

<!-- set the general package -->
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.sit.gems.activity"
    android:versionCode="1"
    android:versionName="1.0" >

    <!-- don't set a package name in <application> -->
    <application ... >

        <!-- then, declare the activities -->
        <activity
            android:name="com.sit.gems.activity.SplashActivity" ... >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <!-- same package here -->
        <activity
            android:name="com.sit.gems.activity.HomeActivity" ... >
        </activity>
    </application>
</manifest>  

4. Don't get lost with layouts:

You should set another layout for SplashScreenActivity.java because you're not using the TabHost for the splash screen and this is not a safe resource way. Declare a specific layout with something different, like the app name and the logo:

// inside SplashScreen class
setContentView(R.layout.splash_screen);

// layout splash_screen.xml
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="match_parent" 
     android:gravity="center"
     android:text="@string/appname" />  

Avoid using a layout in activities which don't use it.

5. Splash Screen?

Finally, I don't understand clearly the purpose of your SplashScreenActivity. It sets a content view and directly finish. This is useless.

As its name is Splash Screen, I assume that you want to display a screen before launching your HomeActivity. Therefore, you should do this and don't use the TabHost layout ;):

// FragmentActivity is also useless here! You don't use a Fragment into it, so, use traditional Activity
public class SplashActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // set your splash_screen layout
        setContentView(R.layout.splash_screen);

        // create a new Thread
        new Thread(new Runnable() {
            public void run() {
                try {
                    // sleep during 800ms
                    Thread.sleep(800);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                // start HomeActivity
                startActivity(new Intent(SplashActivity.this, HomeActivity.class));
                SplashActivity.this.finish();
            }
        }).start();
    }
}  

I hope this kind of tips help you to achieve what you want.
If it's not the case, let me know how can I help you.

Try this code :

 <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center_horizontal">

            <ImageView
                android:id="@+id/imgBusiness"
                android:layout_width="40dp"
                android:layout_height="40dp"
                android:src="@drawable/back_detail" />
</LinearLayout>

I know I'm very late but now you can use the "min-height" style attribute to achieve your purpose.

Perhaps the whole column full of random numbers is not the best way to do it, but it seems like probably the most practical as @mariusnn mentioned.

On that note, this stomped me for a while with Office 2010, and while generally answers like the one in lifehacker work,I just wanted to share an extra step required for the numbers to be unique:

1. Create a new column next to the list that you're going to randomize
2. Type in =rand() in the first cell of the new column - this will generate a random number between 0 and 1

3. Fill the column with that formula. The easiest way to do this may be to:

   • go down along the new column up until the last cell that you want to randomize
   • hold down Shift and click on the last cell
   • press Ctrl+D

4. Now you should have a column of identical numbers, even though they are all generated randomly.

   

   The trick here is to recalculate them! Go to the Formulas tab and then click on Calculate Now (or press F9).

   

   Now all the numbers in the column will be actually generated randomly.

5. Go to the Home tab and click on Sort & Filter. Choose whichever order you want (Smallest to Largest or Largest to Smallest) - whichever one will give you a random order with respect to the original order. Then click OK when the Sort Warning prompts you to Expand the selection.

6. Your list should be randomized now! You can get rid of the column of random numbers if you want.

For the case that you wish to revert a recently installed package that made several changes to dependencies (such as tensorflow), you can "roll back" to an earlier installation state via the following method:

conda list --revisions
conda install --revision [revision number]

The first command shows previous installation revisions (with dependencies) and the second reverts to whichever revision number you specify.

Note that if you wish to (re)install a later revision, you may have to sequentially reinstall all intermediate versions. If you had been at revision 23, reinstalled revision 20 and wish to return, you may have to run each:

conda install --revision 21
conda install --revision 22
conda install --revision 23

If the array contains both positive and negative data, I'd go with:

import numpy as np

a = np.random.rand(3,2)

# Normalised [0,1]
b = (a - np.min(a))/np.ptp(a)

# Normalised [0,255] as integer: don't forget the parenthesis before astype(int)
c = (255*(a - np.min(a))/np.ptp(a)).astype(int)        

# Normalised [-1,1]
d = 2.*(a - np.min(a))/np.ptp(a)-1

If the array contains nan, one solution could be to just remove them as:

def nan_ptp(a):
    return np.ptp(a[np.isfinite(a)])

b = (a - np.nanmin(a))/nan_ptp(a)

However, depending on the context you might want to treat nan differently. E.g. interpolate the value, replacing in with e.g. 0, or raise an error.

Finally, worth mentioning even if it's not OP's question, standardization:

e = (a - np.mean(a)) / np.std(a)

Since GDB 7.5 you can use these native Convenience Functions:

$_memeq(buf1, buf2, length)
$_regex(str, regex)
$_streq(str1, str2)
$_strlen(str)

Seems quite less problematic than having to execute a "foreign" strcmp() on the process' stack each time the breakpoint is hit. This is especially true for debugging multithreaded processes.

Note your GDB needs to be compiled with Python support, which is not an issue with current linux distros. To be sure, you can check it by running show configuration inside GDB and searching for --with-python. This little oneliner does the trick, too:

$ gdb -n -quiet -batch -ex 'show configuration' | grep 'with-python'
             --with-python=/usr (relocatable)

For your demo case, the usage would be

break <where> if $_streq(x, "hello")

or, if your breakpoint already exists and you just want to add the condition to it

condition <breakpoint number> $_streq(x, "hello")

$_streq only matches the whole string, so if you want something more cunning you should use $_regex, which supports the Python regular expression syntax.

On Linux when write()ing into a socket which the other side, unknown to you, closed will provoke a SIGPIPE signal/exception however you want to call it. However if you don't want to be caught out by the SIGPIPE you can use send() with the flag MSG_NOSIGNAL. The send() call will return with -1 and in this case you can check errno which will tell you that you tried to write a broken pipe (in this case a socket) with the value EPIPE which according to errno.h is equivalent to 32. As a reaction to the EPIPE you could double back and try to reopen the socket and try to send your information again.

If you want to access to base class data you must use "this" keyword or you use this keyword as reference for class.

namespace thiskeyword
{
    class Program
    {
        static void Main(string[] args)
        {
            I i = new I();
            int res = i.m1();
            Console.WriteLine(res);
            Console.ReadLine();
        }
    }

    public class E
    {
        new public int x = 3;
    }

    public class F:E
    {
        new public int x = 5;
    }

    public class G:F
    {
        new public int x = 50;
    }

    public class H:G
    {
        new public int x = 20;
    }

    public class I:H
    {
        new public int x = 30;

        public int m1()
        {
           // (this as <classname >) will use for accessing data to base class

            int z = (this as I).x + base.x + (this as G).x + (this as F).x + (this as E).x; // base.x refer to H
            return z;
        }
    }
}

For those still having this issue, my issue was resolved in the AndroidManifest.xml file. Where it says <activity android:name=".MainActivity" android:theme="@style/AppTheme.NoActionBar">, you need to remove NoActionBar, making it <activity android:name=".MainActivity" android:theme="@style/AppTheme">, because with NoActionBar set the app doesnt know whether or not it wants an action bar when you call one up inside of MainActivity.java

Simplest way is to use dimensions in % or em. Just change the base font size everything will change.

Less

@media (max-width: @screen-xs) {
    body{font-size: 10px;}
}

@media (max-width: @screen-sm) {
    body{font-size: 14px;}
}


h5{
    font-size: 1.4rem;
}       

Look at all the ways at https://stackoverflow.com/a/21981859/406659

You could use viewport units (vh,vw...) but they dont work on Android < 4.4

Suppose you need to pass an arraylist of following class from current activity to next activity // class of the objects those in the arraylist // remember to implement the class from Serializable interface // Serializable means it converts the object into stream of bytes and helps to transfer that object

public class Question implements Serializable {
... 
... 
...
}

in your current activity you probably have an ArrayList as follows

ArrayList<Question> qsList = new ArrayList<>();
qsList.add(new Question(1));
qsList.add(new Question(2));
qsList.add(new Question(3));

// intialize Bundle instance
Bundle b = new Bundle();
// putting questions list into the bundle .. as key value pair.
// so you can retrieve the arrayList with this key
b.putSerializable("questions", (Serializable) qsList);
Intent i = new Intent(CurrentActivity.this, NextActivity.class);
i.putExtras(b);
startActivity(i);

in order to get the arraylist within the next activity

//get the bundle
Bundle b = getIntent().getExtras();
//getting the arraylist from the key
ArrayList<Question> q = (ArrayList<Question>) b.getSerializable("questions");

You have to put div with single quotation around it. ' ' the Div must be in the middle of single quotation . i'm gonna clear it with one example :

<?php
        echo '<div id="output">'."Identify".'<br>'.'<br>';
        echo 'Welcome '."$name";
        echo "<br>";
        echo 'Web Mail: '."$email";
        echo "<br>";
        echo 'Department of '."$dep";
        echo "<br>";
        echo "$maj";
        '</div>'
?>

hope be useful.

You can choose the url where the form must be posted (and thus, the invoked action) in different ways, depending on the browser support:

• for newer browsers that support HTML5, you can use formaction attribute of a submit button
• for older browsers that don't support this, you need to use some JavaScript that changes the form's action attribute, when the button is clicked, and before submitting

In this way you don't need to do anything special on the server side.

Of course, you can use Url extensions methods in your Razor to specify the form action.

For browsers supporting HMTL5: simply define your submit buttons like this:

<input type='submit' value='...' formaction='@Url.Action(...)' />

For older browsers I recommend using an unobtrusive script like this (include it in your "master layout"):

$(document).on('click', '[type="submit"][data-form-action]', function (event) {
  var $this = $(this);
  var formAction = $this.attr('data-form-action');
  $this.closest('form').attr('action', formAction);
});

NOTE: This script will handle the click for any element in the page that has type=submit and data-form-action attributes. When this happens, it takes the value of data-form-action attribute and set the containing form's action to the value of this attribute. As it's a delegated event, it will work even for HTML loaded using AJAX, without taking extra steps.

Then you simply have to add a data-form-action attribute with the desired action URL to your button, like this:

<input type='submit' data-form-action='@Url.Action(...)' value='...'/>

Note that clicking the button changes the form's action, and, right after that, the browser posts the form to the desired action.

As you can see, this requires no custom routing, you can use the standard Url extension methods, and you have nothing special to do in modern browsers.

Try adding 2 spaces (or a backslash \) after the first line:

[Name of link](url)
My line of text\

Visually:

[Name of link](url)<space><space>
My line of text\

Output:

<p><a href="url">Name of link</a><br>
My line of text<br></p>

Try Clink. It's awesome, especially if you are used to bash keybindings and features.

(As already pointed out - there is a similar question: Is there a better Windows Console Window?)

The setup:

public interface Predicate<T> {
  public boolean filter(T t);
}

void filterCollection(Collection<T> col, Predicate<T> predicate) {
  for (Iterator i = col.iterator(); i.hasNext();) {
    T obj = i.next();
    if (predicate.filter(obj)) {
      i.remove();
    }
  }
}

The usage:

List<MyObject> myList = ...;
filterCollection(myList, new Predicate<MyObject>() {
  public boolean filter(MyObject obj) {
    return obj.shouldFilter();
  }
});

When your are trying to apply prod on string type of value like:

['-214' '-153' '-58' ..., '36' '191' '-37']

you will get the error.

Solution: Append only integer value like [1,2,3], and you will get your expected output.

If the value is in string format before appending then, in the array you can convert the type into int type and store it in a list.

EPOCH TIME DIFFERENCE USING MOMENTJS:

To Get Difference between two epoch times:

Syntax: moment.duration(moment(moment(date1).diff(moment(date2)))).asHours()

Difference in Hours: moment.duration(moment(moment(1590597744551).diff(moment(1590597909877)))).asHours()

Difference in minutes: moment.duration(moment(moment(1590597744551).diff(moment(1590597909877)))).asMinutes().toFixed()

Note: You could remove .toFixed() if you need precise values.

Code:

const moment = require('moment')

console.log('Date 1',moment(1590597909877).toISOString())
console.log('Date 2',moment(1590597744551).toISOString())
console.log('Date1 - Date 2 time diffrence is : ',moment.duration(moment(moment(1590597909877).diff(moment(1590597744551)))).asMinutes().toFixed()+' minutes')

This is an example for converting a CSV file in Python 3:

try:
    inputReader = csv.reader(open(argv[1], encoding='ISO-8859-1'), delimiter=',',quotechar='"')
except IOError:
    pass

As per keras tutorial, you can simply use the same tf.device scope as in regular tensorflow:

with tf.device('/gpu:0'):
    x = tf.placeholder(tf.float32, shape=(None, 20, 64))
    y = LSTM(32)(x)  # all ops in the LSTM layer will live on GPU:0

with tf.device('/cpu:0'):
    x = tf.placeholder(tf.float32, shape=(None, 20, 64))
    y = LSTM(32)(x)  # all ops in the LSTM layer will live on CPU:0

ALTER TABLE tablename AUTO_INCREMENT = 1

If you are using PHP 5.6, the command is:
