On a rather unrelated note: more performance hacks!

• [the first «conjecture» has been finally debunked by @ShreevatsaR; removed]

• When traversing the sequence, we can only get 3 possible cases in the 2-neighborhood of the current element N (shown first):

  1. [even] [odd]
  2. [odd] [even]
  3. [even] [even]

  To leap past these 2 elements means to compute (N >> 1) + N + 1, ((N << 1) + N + 1) >> 1 and N >> 2, respectively.

  Let`s prove that for both cases (1) and (2) it is possible to use the first formula, (N >> 1) + N + 1.

  Case (1) is obvious. Case (2) implies (N & 1) == 1, so if we assume (without loss of generality) that N is 2-bit long and its bits are ba from most- to least-significant, then a = 1, and the following holds:

  (N << 1) + N + 1:     (N >> 1) + N + 1:
  
          b10                    b1
           b1                     b
         +  1                   + 1
         ----                   ---
         bBb0                   bBb
  

  where B = !b. Right-shifting the first result gives us exactly what we want.

  Q.E.D.: (N & 1) == 1 ? (N >> 1) + N + 1 == ((N << 1) + N + 1) >> 1.

  As proven, we can traverse the sequence 2 elements at a time, using a single ternary operation. Another 2× time reduction.

The resulting algorithm looks like this:

uint64_t sequence(uint64_t size, uint64_t *path) {
    uint64_t n, i, c, maxi = 0, maxc = 0;

    for (n = i = (size - 1) | 1; i > 2; n = i -= 2) {
        c = 2;
        while ((n = ((n & 3)? (n >> 1) + n + 1 : (n >> 2))) > 2)
            c += 2;
        if (n == 2)
            c++;
        if (c > maxc) {
            maxi = i;
            maxc = c;
        }
    }
    *path = maxc;
    return maxi;
}

int main() {
    uint64_t maxi, maxc;

    maxi = sequence(1000000, &maxc);
    printf("%llu, %llu\n", maxi, maxc);
    return 0;
}

Here we compare n > 2 because the process may stop at 2 instead of 1 if the total length of the sequence is odd.

[EDIT:]

Let`s translate this into assembly!

MOV RCX, 1000000;



DEC RCX;
AND RCX, -2;
XOR RAX, RAX;
MOV RBX, RAX;

@main:
  XOR RSI, RSI;
  LEA RDI, [RCX + 1];

  @loop:
    ADD RSI, 2;
    LEA RDX, [RDI + RDI*2 + 2];
    SHR RDX, 1;
    SHRD RDI, RDI, 2;    ror rdi,2   would do the same thing
    CMOVL RDI, RDX;      Note that SHRD leaves OF = undefined with count>1, and this doesn't work on all CPUs.
    CMOVS RDI, RDX;
    CMP RDI, 2;
  JA @loop;

  LEA RDX, [RSI + 1];
  CMOVE RSI, RDX;

  CMP RAX, RSI;
  CMOVB RAX, RSI;
  CMOVB RBX, RCX;

  SUB RCX, 2;
JA @main;



MOV RDI, RCX;
ADD RCX, 10;
PUSH RDI;
PUSH RCX;

@itoa:
  XOR RDX, RDX;
  DIV RCX;
  ADD RDX, '0';
  PUSH RDX;
  TEST RAX, RAX;
JNE @itoa;

  PUSH RCX;
  LEA RAX, [RBX + 1];
  TEST RBX, RBX;
  MOV RBX, RDI;
JNE @itoa;

POP RCX;
INC RDI;
MOV RDX, RDI;

@outp:
  MOV RSI, RSP;
  MOV RAX, RDI;
  SYSCALL;
  POP RAX;
  TEST RAX, RAX;
JNE @outp;

LEA RAX, [RDI + 59];
DEC RDI;
SYSCALL;

Use these commands to compile:

nasm -f elf64 file.asm
ld -o file file.o

See the C and an improved/bugfixed version of the asm by Peter Cordes on Godbolt. (editor's note: Sorry for putting my stuff in your answer, but my answer hit the 30k char limit from Godbolt links + text!)

This is possible if the browser supports the download property in anchor elements.

var sampleBytes = new Int8Array(4096);

var saveByteArray = (function () {
    var a = document.createElement("a");
    document.body.appendChild(a);
    a.style = "display: none";
    return function (data, name) {
        var blob = new Blob(data, {type: "octet/stream"}),
            url = window.URL.createObjectURL(blob);
        a.href = url;
        a.download = name;
        a.click();
        window.URL.revokeObjectURL(url);
    };
}());

saveByteArray([sampleBytes], 'example.txt');

base64.b64decode(your_string)

Well first of all you need to assign the finished product to a variable to be able to be printed out:

code_string = base64.b64decode(your_string)

Then like any beginner programmer would know, you would print the results out: Python 2.7x:

print code_string

Python 3.x:

print(code_string)

After the successful decoding, you will get a string about the size of the not yet decoded string. I hope this helps you!

You can use IDR it is a great program to decompile Delphi, it is updated to the current Delphi versions and it has a lot of features.

You could pass the messages as explicit URL parameter (appropriately encoded), or store the messages into session (cookie) variable before redirecting and then get the variable before rendering the template. For example:

from flask import session, url_for

def do_baz():
    messages = json.dumps({"main":"Condition failed on page baz"})
    session['messages'] = messages
    return redirect(url_for('.do_foo', messages=messages))

@app.route('/foo')
def do_foo():
    messages = request.args['messages']  # counterpart for url_for()
    messages = session['messages']       # counterpart for session
    return render_template("foo.html", messages=json.loads(messages))

(encoding the session variable might not be necessary, flask may be handling it for you, but can't recall the details)

Or you could probably just use Flask Message Flashing if you just need to show simple messages.

this is my revisit to this topic, gathering all the information here, plus from other relevant stack overflow questions. It returns images from some provider, while handling out-of-memory conditions and image rotation. It supports gallery, picasa and file managers, like drop box. Usage is simple: as input, the constructor receives the content resolver and the uri. The output is the final bitmap.

/**
 * Creates resized images without exploding memory. Uses the method described in android
 * documentation concerning bitmap allocation, which is to subsample the image to a smaller size,
 * close to some expected size. This is required because the android standard library is unable to
 * create a reduced size image from an image file using memory comparable to the final size (and
 * loading a full sized multi-megapixel picture for processing may exceed application memory budget).

For anyone running into a problem where build automatically is unchecked but the project is still building. Make sure your project isn't deployed to the server in the server tab and told to stay synchronous.

Just thought i'd share this with anyone who needs more clarity on how to achieve this:

myCanvas is a Canvas control and Parent to all other controllers. This code works to neatly resize to any resolution from 1366 x 768 upward. Tested up to 4k resolution 4096 x 2160

Take note of all the MainWindow property settings (WindowStartupLocation, SizeToContent and WindowState) - important for this to work correctly - WindowState for my user case requirement was Maximized

Strings always evaluate to boolean true unless they have a value that's considered "empty" by PHP (taken from the documentation for empty):

1. "" (an empty string);
2. "0" (0 as a string)

If you need to set a boolean based on the text value of a string, then you'll need to check for the presence or otherwise of that value.

$test_mode_mail = $string === 'true'? true: false;

EDIT: the above code is intended for clarity of understanding. In actual use the following code may be more appropriate:

$test_mode_mail = ($string === 'true');

or maybe use of the filter_var function may cover more boolean values:

filter_var($string, FILTER_VALIDATE_BOOLEAN);

filter_var covers a whole range of values, including the truthy values "true", "1", "yes" and "on". See here for more details.

As Filburt says; but also note that it's usually better to write

test="not(Count = 'N/A')"

If there's exactly one Count element they mean the same thing, but if there's no Count, or if there are several, then the meanings are different.

6 YEARS LATER

Since this answer seems to have become popular, but may be a little cryptic to some readers, let me expand it.

The "=" and "!=" operator in XPath can compare two sets of values. In general, if A and B are sets of values, then "=" returns true if there is any pair of values from A and B that are equal, while "!=" returns true if there is any pair that are unequal.

In the common case where A selects zero-or-one nodes, and B is a constant (say "NA"), this means that not(A = "NA") returns true if A is either absent, or has a value not equal to "NA". By contrast, A != "NA" returns true if A is present and not equal to "NA". Usually you want the "absent" case to be treated as "not equal", which means that not(A = "NA") is the appropriate formulation.

WAY-1 : Updated for the shortest and easy way

Below command will give you the path, But it will only work if java command is working in other words if java path is configured.

readlink -f $(which java) 

Read more at Where can I find the Java SDK in Linux?

WAY-2 (Better than WAY-1) : Below answer is still working and try it if above command is not working for you.

You need to dig into symbolic links. Below is steps to get Java directory

Step 1:

$ whereis java
java: /usr/bin/java /etc/java /usr/share/java

That tells the command java resides in /usr/bin/java.

Dig again:

Step 2:

$ ls -l /usr/bin/java
lrwxrwxrwx 1 root root 22 2009-01-15 18:34 /usr/bin/java -> /etc/alternatives/java

So, now we know that /usr/bin/java is actually a symbolic link to /etc/alternatives/java.

Dig deeper using the same method above:

Step 3:

$ ls -l /etc/alternatives/java
lrwxrwxrwx 1 root root 31 2009-01-15 18:34 /etc/alternatives/java -> /usr/local/jre1.6.0_07/bin/java

So, thats the actual location of java: /usr/local/jre.....

You could still dig deeper to find other symbolic links.

Reference : where is java's home dir?

The short answer would be:

CommonJS and AMD are specifications (or formats) on how modules and their dependencies should be declared in javascript applications.

RequireJS is a script loader library that is AMD compliant, curljs being another example.

CommonJS compliant:

Taken from Addy Osmani's book.

// package/lib is a dependency we require
var lib = require( "package/lib" );

// behavior for our module
function foo(){
    lib.log( "hello world!" );
}

// export (expose) foo to other modules as foobar
exports.foobar = foo;

AMD compliant:

// package/lib is a dependency we require
define(["package/lib"], function (lib) {

    // behavior for our module
    function foo() {
        lib.log( "hello world!" );
    }

    // export (expose) foo to other modules as foobar
    return {
        foobar: foo
    }
});

Somewhere else the module can be used with:

require(["package/myModule"], function(myModule) {
    myModule.foobar();
});

Some background:

Actually, CommonJS is much more than an API declaration and only a part of it deals with that. AMD started as a draft specification for the module format on the CommonJS list, but full consensus wasn't reached and further development of the format moved to the amdjs group. Arguments around which format is better state that CommonJS attempts to cover a broader set of concerns and that it's better suited for server side development given its synchronous nature, and that AMD is better suited for client side (browser) development given its asynchronous nature and the fact that it has its roots in Dojo's module declaration implementation.

Sources:

• RequireJS - Why AMD?
• Addy Osmani - Learning JavaScript Design Patterns - Modern Modular JavaScript Design Patterns

Take a look at http://dev.mysql.com/doc/refman/5.0/en/declare-handler.html

Basically you declare error handler which will call rollback

START TRANSACTION;

DECLARE EXIT HANDLER FOR SQLEXCEPTION 
    BEGIN
        ROLLBACK;
        EXIT PROCEDURE;
    END;
COMMIT;

I have used the exact steps from here and it worked flawlessly : https://docs.microsoft.com/en-us/visualstudio/install/install-vs-inconsistent-quality-network

In 3 simple steps:

Step 1 : Download the respective Visual Studio 2017 version from the download page (https://www.visualstudio.com/downloads/)

Step 2: Open your command prompt as Administarator, point to where your Visual studio download exe is and execute the following command (this command is specifically for Web & Desktop development) :

vs_community.exe --layout c:\vs2017layout --add Microsoft.VisualStudio.Workload.ManagedDesktop --add Microsoft.VisualStudio.Workload.NetWeb --add Component.GitHub.VisualStudio --includeOptional --lang en-US

Step 3 : Traverse to the path c:\vs2017layout in your command prompt and then run the following command (this command is specifically for Web & Desktop development)

vs_community.exe --add Microsoft.VisualStudio.Workload.ManagedDesktop --add Microsoft.VisualStudio.Workload.NetWeb --add Component.GitHub.VisualStudio --includeOptional

String path ="AnyDirectory/subFolder/last.htm";
int pos = path.lastIndexOf("/") + 1;

path.substring(pos, path.length()-pos) ;

Now you have the last.htm in the path string.

Even I had also observed the similar problem. I had closed my eclipse project because of some reason and on restart some of my file added were not visible in explorer even though corresponding file were existing.

Following solution worked for me: Select whole workspace (Ctrl+A) ==> Righ click and press Refresh.

I suggest you to start with simple polynomial fit, scipy.optimize.curve_fit tries to fit a function f that you must know to a set of points.

This is a simple 3 degree polynomial fit using numpy.polyfit and poly1d, the first performs a least squares polynomial fit and the second calculates the new points:

import numpy as np
import matplotlib.pyplot as plt

points = np.array([(1, 1), (2, 4), (3, 1), (9, 3)])
# get x and y vectors
x = points[:,0]
y = points[:,1]

# calculate polynomial
z = np.polyfit(x, y, 3)
f = np.poly1d(z)

# calculate new x's and y's
x_new = np.linspace(x[0], x[-1], 50)
y_new = f(x_new)

plt.plot(x,y,'o', x_new, y_new)
plt.xlim([x[0]-1, x[-1] + 1 ])
plt.show()

I wouldn't use a Regex for this, but rather just split the string and check that the date is valid:

list($year, $month, $day, $hour, $minute, $second) = preg_split('%( |-|:)%', $mydatestring);
if(!checkdate($month, $day, $year)) {
     /* print error */
} 
/* check $hour, $minute and $second etc */

I made an extension method based on this MSDN article. This is how you can determine whether a socket is still connected.

public static bool IsConnected(this Socket client)
{
    bool blockingState = client.Blocking;

    try
    {
        byte[] tmp = new byte[1];

        client.Blocking = false;
        client.Send(tmp, 0, 0);
        return true;
    }
    catch (SocketException e)
    {
        // 10035 == WSAEWOULDBLOCK
        if (e.NativeErrorCode.Equals(10035))
        {
            return true;
        }
        else
        {
            return false;
        }
    }
    finally
    {
        client.Blocking = blockingState;
    }
}

The main differences between github and gists are in terms of number of features and user interface:

One is designed with a great number of features and flexibility in mind, which is a good fit for both small and very big projects, while gists are only a good fit for very small projects.

For example, gists do support multi-files, but the interface is very simple, and they're limited in features, so they don't even have a file browser, nor issues, pull requests or wiki. If you dont need to have that, gists are very nice and more discrete. Like the comments, instead of answers, in SO.

Is there a command that does?

thread apply all where

You can use the ThenBy and ThenByDescending extension methods:

foobarList.OrderBy(x => x.Foo).ThenBy( x => x.Bar)

It's a logic bomb, it keeps recreating itself and takes up all your CPU resources. It overloads your computer with too many processes and it forces it to shut down. If you make a batch file with this in it and start it you can end it using taskmgr. You have to do this pretty quickly or your computer will be too slow to do anything.

The typical way is with scanf:

int input_value;

scanf("%d", &input_value);

In most cases, however, you want to check whether your attempt at reading input succeeded. scanf returns the number of items it successfully converted, so you typically want to compare the return value against the number of items you expected to read. In this case you're expecting to read one item, so:

if (scanf("%d", &input_value) == 1)
    // it succeeded
else
    // it failed

Of course, the same is true of all the scanf family (sscanf, fscanf and so on).

The solution consists in a regex pattern matching open and closing parenthesis

String str = "Your(String)";
// parameter inside split method is the pattern that matches opened and closed parenthesis, 
// that means all characters inside "[ ]" escaping parenthesis with "\\" -> "[\\(\\)]"
String[] parts = str.split("[\\(\\)]");
for (String part : parts) {
   // I print first "Your", in the second round trip "String"
   System.out.println(part);
}

Writing in Java 8's style, this can be solved in this way:

Arrays.asList("Your(String)".split("[\\(\\)]"))
    .forEach(System.out::println);

I hope it is clear.

Thanks, @jowett, I have solved my same problem, doing these steps

Step 1: CTRL+Shift+Esc to open the task manager, which has adb.exe process and end (kill) that process

Step 2: Now, close the eclipse, which is currently running on my computer.

Step 3: Again, restart eclipse then solved that problem.

For those using OS X

killall adb

For those using Windows

adb kill-server

should do the trick.

if (x.equals(y))

This looks like an expensive operation. Are there any hash codes calculated this way?

It is not an expensive operation and no hash codes are calculated. Java does not magically calculate hash codes, equals(...) is just a method call, not different from any other method call.

The JVM will most likely even optimize the method call away (inlining the comparison that takes place inside the method), so this call is not much more expensive than using == on two primitive int values.

Note: Don't prematurely apply micro-optimizations; your assumptions like "this must be slow" are most likely wrong or don't matter, because the code isn't a performance bottleneck.

Just add

xAxis: {
   ...  
   lineWidth: 0,
   minorGridLineWidth: 0,
   lineColor: 'transparent',
   ...          
   labels: {
       enabled: false
   },
   minorTickLength: 0,
   tickLength: 0
}

to the xAxis definition.

Since Version 4.1.9 you can simply use the axis attribute visible:

xAxis: {
    visible: false,
}

You can't put a div directly inside a table but you can put div inside td or th element.

For that you need to do is make sure the div is inside an actual table cell, a td or th element, so do that:

HTML:-

<tr>
  <td>
    <div>
      <p>I'm text in a div.</p>
    </div>
  </td>
</tr>

For more information :-

If you truly want to confirm that a variable is not null and not an empty string specifically, you would write:

if(data !== null && data !== '') {
   // do something
}

Notice that I changed your code to check for type equality (!==|===).

If, however you just want to make sure, that a code will run only for "reasonable" values, then you can, as others have stated already, write:

if (data) {
  // do something
}

Since, in javascript, both null values, and empty strings, equals to false (i.e. null == false).

The difference between those 2 parts of code is that, for the first one, every value that is not specifically null or an empty string, will enter the if. But, on the second one, every true-ish value will enter the if: false, 0, null, undefined and empty strings, would not.

4 years late on the topic, but this might be helpful to someone.

If you forgot to create a new branch before committing and committed all on master, no matter how many commits you did, the following approach is easier:

git stash                       # skip if all changes are committed
git branch my_feature
git reset --hard origin/master
git checkout my_feature
git stash pop                   # skip if all changes were committed

Now you have your master branch equals to origin/master and all new commits are on my_feature. Note that my_feature is a local branch, not a remote one.

You can restart the database on RDS Admin.

to handle undefined, null, and NaN: Null behaves like 0, NaN and undefined goes to end.

array = [3, 5, -1, 1, NaN, 6, undefined, 2, null]
array.sort((a,b) => isNaN(a) || a-b)
// [-1, null, 1, 2, 3, 5, 6, NaN, undefined]

How about trying:

select * from 'test_table'
where end_date < CAST('2009-12-15' AS DATE)
or start_date > CAST('2010-01-02' AS DATE)

which will return all date ranges which do not overlap your date range at all.

Pass address of a function as parameter to another function as shown below

#include <stdio.h>

void print();
void execute(void());

int main()
{
    execute(print); // sends address of print
    return 0;
}

void print()
{
    printf("Hello!");
}

void execute(void f()) // receive address of print
{
    f();
}

Also we can pass function as parameter using function pointer

#include <stdio.h>

void print();
void execute(void (*f)());

int main()
{
    execute(&print); // sends address of print
    return 0;
}

void print()
{
    printf("Hello!");
}

void execute(void (*f)()) // receive address of print
{
    f();
}

To create an option that needs no value, set the action ^[docs] of it to 'store_const', 'store_true' or 'store_false'.

Example:

parser.add_argument('-s', '--simulate', action='store_true')

I did like this-

$("#drpServices").select2().val("0").trigger("change");

You can use the excellent pandas, which has a built in clipboard support, but you need to pass through a DataFrame.

import pandas as pd
df=pd.DataFrame(['Text to copy'])
df.to_clipboard(index=False,header=False)

Just assuming this is for a regular expression, use re.escape.

public boolean isAlertPresent()

    catch (NoAlertPresentException Ex) 
    { 
        return false; 
    }   // catch

In python you can do this very eaisly

start=0
end=10
arr=list(range(start,end+1))
output: arr=[0,1,2,3,4,5,6,7,8,9,10]

or you can create a recursive function that returns an array upto a given number:

ar=[]
def diff(start,end):
    if start==end:
        d.append(end)
        return ar
    else:
        ar.append(end)
        return diff(start-1,end) 

output: ar=[10,9,8,7,6,5,4,3,2,1,0]

Does your cacerts.pem file hold a single certificate? Since it is a PEM, have a look at it (with a text editor), it should start with

-----BEGIN CERTIFICATE-----

and end with

-----END CERTIFICATE-----

Finally, to check it is not corrupted, get hold of openssl and print its details using

openssl x509 -in cacerts.pem -text

Here is my solution that doesn't have any dependencies:

return value
  .replace(/[^\d\-.,]/g, "")   // Basic sanitization. Allows '-' for negative numbers
  .replace(/,/g, ".")          // Change all commas to periods
  .replace(/\.(?=.*\.)/g, ""); // Remove all periods except the last one

(I left out the conversion to a number - that's probably just a parseFloat call if you don't care about JavaScript's precision problems with floats.)

The code assumes that:

• Only commas and periods are used as decimal separators. (I'm not sure if locales exist that use other ones.)
• The decimal part of the string does not use any separators.

I ran into the same problem, and here is how I fixed it:

private final class UIHandler extends Handler
{
    public static final int DISPLAY_UI_TOAST = 0;
    public static final int DISPLAY_UI_DIALOG = 1;

    public UIHandler(Looper looper)
    {
        super(looper);
    }

    @Override
    public void handleMessage(Message msg)
    {
        switch(msg.what)
        {
        case UIHandler.DISPLAY_UI_TOAST:
        {
            Context context = getApplicationContext();
            Toast t = Toast.makeText(context, (String)msg.obj, Toast.LENGTH_LONG);
            t.show();
        }
        case UIHandler.DISPLAY_UI_DIALOG:
            //TBD
        default:
            break;
        }
    }
}

protected void handleUIRequest(String message)
{
    Message msg = uiHandler.obtainMessage(UIHandler.DISPLAY_UI_TOAST);
    msg.obj = message;
    uiHandler.sendMessage(msg);
}

To create the UIHandler, you'll need to perform the following:

    HandlerThread uiThread = new HandlerThread("UIHandler");
    uiThread.start();
    uiHandler = new UIHandler((HandlerThread) uiThread.getLooper());

Hope this helps.

The SQL Server Maximums are disclosed http://msdn.microsoft.com/en-us/library/ms143432.aspx (this is the 2008 version)

A SQL Query can be a varchar(max) but is shown as limited to 65,536 * Network Packet size, but even then what is most likely to trip you up is the 2100 parameters per query. If SQL chooses to parameterize the literal values in the in clause, I would think you would hit that limit first, but I havn't tested it.

Edit : Test it, even under forced parameteriztion it survived - I knocked up a quick test and had it executing with 30k items within the In clause. (SQL Server 2005)

At 100k items, it took some time then dropped with:

Msg 8623, Level 16, State 1, Line 1 The query processor ran out of internal resources and could not produce a query plan. This is a rare event and only expected for extremely complex queries or queries that reference a very large number of tables or partitions. Please simplify the query. If you believe you have received this message in error, contact Customer Support Services for more information.

So 30k is possible, but just because you can do it - does not mean you should :)

Edit : Continued due to additional question.

50k worked, but 60k dropped out, so somewhere in there on my test rig btw.

In terms of how to do that join of the values without using a large in clause, personally I would create a temp table, insert the values into that temp table, index it and then use it in a join, giving it the best opportunities to optimse the joins. (Generating the index on the temp table will create stats for it, which will help the optimiser as a general rule, although 1000 GUIDs will not exactly find stats too useful.)

How I would write it:

var left: Node? = null

fun show() {
     val left = left ?: return
     queue.add(left) // no error because we return if it is null
}

Even more simple, pass the $event object to ng-click to access the event properties. As an example:

<a ng-click="clickEvent($event)" class="exampleClass" id="exampleID" data="exampleData" href="">Click Me</a>

Within your clickEvent() = function(obj) {} function you can access the data value like this:

var dataValue = obj.target.attributes.data.value;

Which would return exampleData.

Here's a full jsFiddle.

When you pass a pointer by a non-const reference, you are telling the compiler that you are going to modify that pointer's value. Your code does not do that, but the compiler thinks that it does, or plans to do it in the future.

To fix this error, either declare x constant

// This tells the compiler that you are not planning to modify the pointer
// passed by reference
void test(float * const &x){
    *x = 1000;
}

or make a variable to which you assign a pointer to nKByte before calling test:

float nKByte = 100.0;
// If "test()" decides to modify `x`, the modification will be reflected in nKBytePtr
float *nKBytePtr = &nKByte;
test(nKBytePtr);

To me the best way is -

1. Create an new issue with that repository on github and then upload the file in gif format.To convert video files into gif format you can use this website http://www.online-convert.com/

I'll try to answer several key points: this is from long Hibernate/ persistence experience including several major applications.

Entity Class: implement Serializable?

Keys needs to implement Serializable. Stuff that's going to go in the HttpSession, or be sent over the wire by RPC/Java EE, needs to implement Serializable. Other stuff: not so much. Spend your time on what's important.

Constructors: create a constructor with all required fields of the entity?

Constructor(s) for application logic, should have only a few critical "foreign key" or "type/kind" fields which will always be known when creating the entity. The rest should be set by calling the setter methods -- that's what they're for.

Avoid putting too many fields into constructors. Constructors should be convenient, and give basic sanity to the object. Name, Type and/or Parents are all typically useful.

OTOH if application rules (today) require a Customer to have an Address, leave that to a setter. That is an example of a "weak rule". Maybe next week, you want to create a Customer object before going to the Enter Details screen? Don't trip yourself up, leave possibility for unknown, incomplete or "partially entered" data.

Constructors: also, package private default constructor?

Yes, but use 'protected' rather than package private. Subclassing stuff is a real pain when the necessary internals are not visible.

Fields/Properties

Use 'property' field access for Hibernate, and from outside the instance. Within the instance, use the fields directly. Reason: allows standard reflection, the simplest & most basic method for Hibernate, to work.

As for fields 'immutable' to the application -- Hibernate still needs to be able to load these. You could try making these methods 'private', and/or put an annotation on them, to prevent application code making unwanted access.

Note: when writing an equals() function, use getters for values on the 'other' instance! Otherwise, you'll hit uninitialized/ empty fields on proxy instances.

Protected is better for (Hibernate) performance?

Unlikely.

Equals/HashCode?

This is relevant to working with entities, before they've been saved -- which is a thorny issue. Hashing/comparing on immutable values? In most business applications, there aren't any.

A customer can change address, change the name of their business, etc etc -- not common, but it happens. Corrections also need to be possible to make, when the data was not entered correctly.

The few things that are normally kept immutable, are Parenting and perhaps Type/Kind -- normally the user recreates the record, rather than changing these. But these do not uniquely identify the entity!

So, long and short, the claimed "immutable" data isn't really. Primary Key/ ID fields are generated for the precise purpose, of providing such guaranteed stability & immutability.

You need to plan & consider your need for comparison & hashing & request-processing work phases when A) working with "changed/ bound data" from the UI if you compare/hash on "infrequently changed fields", or B) working with "unsaved data", if you compare/hash on ID.

Equals/HashCode -- if a unique Business Key is not available, use a non-transient UUID which is created when the entity is initialized

Yes, this is a good strategy when required. Be aware that UUIDs are not free, performance-wise though -- and clustering complicates things.

Equals/HashCode -- never refer to related entities

"If related entity (like a parent entity) needs to be part of the Business Key then add a non insertable, non updatable field to store the parent id (with the same name as the ManytoOne JoinColumn) and use this id in the equality check"

Sounds like good advice.

Hope this helps!

I had the same problem, I changed the FXML name to the FXML file in the controller class and the problem was solved.

Use std::bitset

#include <bitset>
#include <iostream>

int main()
{
    int temp = 0x5E;
    std::bitset<sizeof(int)*CHAR_BITS>   bits(temp);

    // 0 -> bit 1
    // 2 -> bit 3
    std::cout << bits[2] << std::endl;
}

I know this is an old thread, but I landed here when my row deletes were blocked by foreign key constraints. In my case, my table design permitted "NULL" values in the constrained column. In the rows to be deleted, I changed the constrained column value to "NULL" (which does not violate the Foreign Key Constraint) and then deleted all the rows.

You can use std::make_pair

revenue.push_back(std::make_pair("string",map[i].second));

In my tests, Enum.GetName was faster and by decent margin. Internally ToString calls Enum.GetName. From source for .NET 4.0, the essentials:

public override String ToString()
{
     return Enum.InternalFormat((RuntimeType)GetType(), GetValue());
}

private static String InternalFormat(RuntimeType eT, Object value)
{
    if (!eT.IsDefined(typeof(System.FlagsAttribute), false))
    {
        String retval = GetName(eT, value); //<== the one
        if (retval == null)
            return value.ToString();
        else
            return retval;
    }
    else
    {
        return InternalFlagsFormat(eT, value);
    }
}

I cant say that is the reason for sure, but tests state one is faster than the other. Both the calls involve boxing (in fact they are reflection calls, you're essentially retrieving field names) and can be slow for your liking.

Test setup: enum with 8 values, no. of iterations = 1000000

Result: Enum.GetName => 700 ms, ToString => 2000 ms

If speed isn't noticeable, I wouldn't care and use ToString since it offers a much cleaner call. Contrast

Enum.GetName(typeof(Bla), value)

with

value.ToString()

Since you seem to be on windows you can do this so python <filename.py>. Check that python's bin folder is in your PATH, or you can do c:\python23\bin\python <filename.py>. Python is an interpretive language and so you need the interpretor to run your file, much like you need java runtime to run a jar file.

Also check if you have installed the Mongo as a windows service and if its running. That's also important. There might port conflict because of that.

You don't need to create a button. The facility exists by default.

Just right click on the arrow buttons on the bottom left hand corner of the Excel window. These are the arrow buttons which if you left click move left or right one worksheet.

If you right-click on these arrows Excel will pop up a dialogue with a list of worksheets from which you can click to set your chosen sheet active.

If you are using Notepad++ editor (like the tag of the question suggests), you can use the great "Find in Files" functionality.

Go to Search > Find in Files (Ctrl+Shift+F for the keyboard addicted) and enter:

• Find What = (test1|test2)
• Filters = *.txt
• Directory = enter the path of the directory you want to search in. You can check Follow current doc. to have the path of the current file to be filled.
• Search mode = Regular Expression

I needed to do the same and had to query a query to get the result

I set my first query up to bring in all IDs from the table and all other information needed to filter:

SELECT tMAIN.tLOTS.NoContract, tMAIN.ID
FROM tMAIN INNER JOIN tLOTS ON tMAIN.ID = tLOTS.id
WHERE (((tLOTS.NoContract)=False));

Save this as Q04_1 -0 this returned 1229 results (there are 63 unique records to query - soime with multiple LOTs)

SELECT DISTINCT ID
FROM q04_1;

Saved that as q04_2

I then wrote another query which brought in the required information linked to the ID

SELECT q04_2.ID, tMAIN.Customer, tMAIN.Category
FROM q04_2 INNER JOIN tMAIN ON q04_2.ID = tMAIN.ID;

Worked a treat and got me exactly what I needed - 63 unique records returned with customer and category details.

This is how I worked around it as I couldn't get the Group By working at all - although I am rather "wet behind the ears" weith SQL (so please be gentle and constructive with feedback)

let suppose you are using xampp and phpmyadmin

you have file name 'ratings.txt' table name 'ratings' and database name 'movies'

if your xampp is installed in "C:\xampp\"

copy your "ratings.txt" file in "C:\xampp\mysql\data\movies" folder

LOAD DATA INFILE 'ratings.txt' INTO TABLE ratings FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES;

Hope this can help you to omit your error if you are doing this on localhost

I had similar kind of problem and decided to write a script that removes dependencies for me. Using that I got over half of the dependencies away rather easily.

http://samulisiivonen.blogspot.com/2012/01/cleanin-up-maven-dependencies.html

A simple link to the file is the obvious solution here. You just have to make shure that the link is valid and that it really points to a file ...

I just used =COUNTIF(Range, "<>") and it counted non-empty cells for me.

I entered: [C:\Users\user\].gradle\caches\1.8\scripts directory and deleted its content. I didn't had to restart anything, just removed scripts content any rerun it.

In the end I found this to be the best solution considering the requirements:

// Expand/Collapse all
$('.accordion-expand-collapse a').click(function() {
    $('.accordion .ui-accordion-header:not(.ui-state-active)').next().slideToggle();
    $(this).text($(this).text() == 'Expand all' ? 'Collapse all' : 'Expand all');
    $(this).toggleClass('collapse');
    return false;
});

Updated JSFiddle Link: http://jsfiddle.net/ccollins1544/r8j105de/4/

Is this what you are looking for?

Option Explicit

Public Sub addDataToTable(ByVal strTableName As String, ByVal strData As String, ByVal col As Integer)
    Dim lLastRow As Long
    Dim iHeader As Integer

    With ActiveSheet.ListObjects(strTableName)
        'find the last row of the list
        lLastRow = ActiveSheet.ListObjects(strTableName).ListRows.Count
        'shift from an extra row if list has header
        If .Sort.Header = xlYes Then
            iHeader = 1
        Else
            iHeader = 0
        End If
    End With
    'add the data a row after the end of the list
    ActiveSheet.Cells(lLastRow + 1 + iHeader, col).Value = strData
End Sub

It handles both cases whether you have header or not.

You can just use wildcards in the predicate (after IF, WHERE or ON):

@mainstring LIKE '%' + @substring + '%'

or in this specific case

' ' + @mainstring + ' ' LIKE '% ME[., ]%'

(Put the spaces in the quoted string if you're looking for the whole word, or leave them out if ME can be part of a bigger word).

You didn't hear it from me, the PM for Razor, but in Razor 2 (Web Pages 2 and MVC 4) we'll have conditional attributes built into Razor(as of MVC 4 RC tested successfully), so you can just say things like this...

<input type="text" id="@strElementID" class="@strCSSClass" />

If strCSSClass is null then the class attribute won't render at all.

SSSHHH...don't tell. :)

In Kotlin simply use KTX extension function: (It uses TextWatcher)

yourEditText.doOnTextChanged { text, start, count, after -> 
        // action which will be invoked when the text is changing
    }

import core-KTX:

implementation "androidx.core:core-ktx:1.2.0"

replace:

input, select, textarea{
    color: #000;
}

with:

input, select, textarea{
    color: #f00;
}

or color: #ff0000;

Here is a small example how to do it with powermock

public class Hello {
    private Hello obj;
    private Integer method1(Long id) {
        return id + 10;
    }
} 

To test method1 use code:

Hello testObj = new Hello();
Integer result = Whitebox.invokeMethod(testObj, "method1", new Long(10L));

To set private object obj use this:

Hello testObj = new Hello();
Hello newObject = new Hello();
Whitebox.setInternalState(testObj, "obj", newObject);

I have resolved the same problem using the below code:

String query = "SELECT violationDate, COUNT(*) as date " +
            "FROM challan " +
            "WHERE challanType = '" + type + "' GROUP BY violationDate";
    

Here violationDate and date are two columns of the result table. date column will return occurrence.

cr.getInt(1)

Use:

sb.AppendLine();
sb.Append("\t");

for better portability. Environment.NewLine may not necessarily be \n; Windows uses \r\n, for example.

After uncommenting disable_overscan=1 follow my lead. In the link, http://elinux.org/RPiconfig when you search for Video options, you'll also get hdmi_group and hdmi_mode. For, hdmi_group choose 1 if you're using you TV as an video output or choose 2 for monitors. Then in hdmi_mode, you can select the resolution you want from the list. I chose :- hdmi_group=2 hdmi_mode=23 And it worked.

This is not a shell script, but it is the cli tool I'm using to convert numbers among bin/oct/dec/hex:

    #!/usr/bin/perl

    if (@ARGV < 2) {
      printf("Convert numbers among bin/oct/dec/hex\n");
      printf("\nUsage: base b/o/d/x num num2 ... \n");
      exit;
    }

    for ($i=1; $i<@ARGV; $i++) {
      if ($ARGV[0] eq "b") {
                    $num = oct("0b$ARGV[$i]");
      } elsif ($ARGV[0] eq "o") {
                    $num = oct($ARGV[$i]);
      } elsif ($ARGV[0] eq "d") {
                    $num = $ARGV[$i];
      } elsif ($ARGV[0] eq "h") {
                    $num = hex($ARGV[$i]);
      } else {
                    printf("Usage: base b/o/d/x num num2 ... \n");
                    exit;
      }
      printf("0x%x = 0d%d = 0%o = 0b%b\n", $num, $num, $num, $num);

Since mysql_* are deprecated, so here is the solution using mysqli.

$mysqli = new mysqli('host', 'username', 'password', 'database');
if($mysqli->connect_errno>0)
{
  die("Connection to MySQL-server failed!");

$resultArr = array();//to store results
//to execute query
$executingFetchQuery = $mysqli->query("SELECT `name` FROM customers WHERE 1");
if($executingFetchQuery)
{
   while($arr = $executingFetchQuery->fetch_assoc())
   {
        $resultArr[] = $arr['name'];//storing values into an array
   }
}
print_r($resultArr);//print the rows returned by query, containing specified columns

There is another way to do this using PDO

  $db = new PDO('mysql:host=host_name;dbname=db_name', 'username', 'password'); //to establish a connection
  //to fetch records
  $fetchD = $db->prepare("SELECT `name` FROM customers WHERE 1");
  $fetchD->execute();//executing the query
  $resultArr = array();//to store results
  while($row = $fetchD->fetch())
  {
     $resultArr[] = $row['name'];
  }
  print_r($resultArr);

<span ng-if="verifyName.indicator == 1"><i class="fa fa-check"></i></span>
<span ng-if="verifyName.indicator == 0"><i class="fa fa-times"></i></span>

try this code. here verifyName.indicator value is coming from controller. this works for me.

enter as root (sudo su) and try this:

unset DOCKER_HOST
docker run --name mynginx1 -P -d nginx

I've the same problem here, and the docker command only worked running as root, and also with this DOCKER_HOST empty

PS: also beware that the correct and official way to install on Ubuntu is to use their apt repositories (even on 15.10), not with that "wget" thing.

As previously mentioned - in case of a project, Makefile or otherwise, this is a project configuration issue, where you'll likely need to specify other flags too.

But what about one-off programs, where you would normally just write g++ file.cpp && ./a.out?

Well, I would much like to have some #pragma to turn in on at source level, or maybe a default extension - say .cxx or .C11 or whatever, trigger it by default. But as of today, there is no such feature.

But, as you probably are working in a manual environment (i.e. shell), you can just have an alias in you .bashrc (or whatever):

alias g++11="g++ -std=c++0x"

or, for newer G++ (and when you want to feel "real C++11")

alias g++11="g++ -std=c++11"

You can even alias to g++ itself, if you hate C++03 that much ;)

This seems to do what you want (I found it on http://huddledmasses.org/powershell-find-path/):

Function Find-Path($Path, [switch]$All = $false, [Microsoft.PowerShell.Commands.TestPathType]$type = "Any")
## You could comment out the function stuff and use it as a script instead, with this line:
#param($Path, [switch]$All = $false, [Microsoft.PowerShell.Commands.TestPathType]$type = "Any")
   if($(Test-Path $Path -Type $type)) {
      return $path
   } else {
      [string[]]$paths = @($pwd);
      $paths += "$pwd;$env:path".split(";")

      $paths = Join-Path $paths $(Split-Path $Path -leaf) | ? { Test-Path $_ -Type $type }
      if($paths.Length -gt 0) {
         if($All) {
            return $paths;
         } else {
            return $paths[0]
         }
      }
   }
   throw "Couldn't find a matching path of type $type"
}
Set-Alias find Find-Path

In summary, two ways were introduced

1) using order by DBMS_RANDOM.VALUE clause
2) using sample([%]) function

The first way has advantage in 'CORRECTNESS' which means you will never fail get result if it actually exists, while in the second way you may get no result even though it has cases satisfying the query condition since information is reduced during sampling.

The second way has advantage in 'EFFICIENT' which mean you will get result faster and give light load to your database. I was given an warning from DBA that my query using the first way gives loads to the database

You can choose one of two ways according to your interest!

I faced a similar issue where XML was containing control characters. After looking into the code, I found that a deprecated class,StringBufferInputStream, was used for reading string content.

http://docs.oracle.com/javase/7/docs/api/java/io/StringBufferInputStream.html

This class does not properly convert characters into bytes. As of JDK 1.1, the preferred way to create a stream from a string is via the StringReader class.

I changed it to ByteArrayInputStream and it worked fine.

Yes, you can store and view images in Firebase. You can use a filepicker to get the image file. Then you can host the image however you want, I prefer Amazon s3. Once the image is hosted you can display the image using the URL generated for the image.

Hope this helps.

It really depends on the filesystem used, and also some flags.

For example, ext3 can have many thousands of files; but after a couple of thousands, it used to be very slow. Mostly when listing a directory, but also when opening a single file. A few years ago, it gained the 'htree' option, that dramatically shortened the time needed to get an inode given a filename.

Personally, I use subdirectories to keep most levels under a thousand or so items. In your case, I'd create 256 directories, with the two last hex digits of the ID. Use the last and not the first digits, so you get the load balanced.

To view the months of the current year, and only the months, use this format - it only takes the months of that year. It can also be restricted so that a certain number of months is displayed.

<input class="form-control" id="txtDateMMyyyy"  autocomplete="off" required readonly/>

<script>
('#txtDateMMyyyy').datetimepicker({
    format: "mm/yyyy",
    startView: "year",
    minView: "year"
}).datetimepicker("setDate", new Date());
</script>

Short answer is that you don't 'decrypt' the password (because it's not encrypted - it's hashed).

The long answer is that you shouldn't send the user their password by email, or any other way. If the user has forgotten their password, you should send them a password reset email, and allow them to change their password on your website.

Laravel has most of this functionality built in (see the Laravel documentation - I'm not going to replicate it all here. Also available for versions 4.2 and 5.0 of Laravel).

For further reading, check out this 'blogoverflow' post: Why passwords should be hashed.

Session State may be broken if you have the following in Web.Config:

<httpModules>
  <clear/>
</httpModules>

If this is the case, you may want to comment out such section, and you won't need any other changes to fix this issue.

Try

$ awk 'NF>1{print $NF}' file
example.
line.
file.

To get the result in one line as in your example, try:

{
    sub(/\./, ",", $NF)
    str = str$NF
}
END { print str }

output:

$ awk -f script.awk file
example, line, file, 

Pure bash:

$ while read line; do [ -z "$line" ] && continue ;echo ${line##* }; done < file
example.
line.
file.

Actually MySQL provide a lot of easy to use function in daily life without more effort from user side-

NOW() it produce date and time both in current scenario whereas CURDATE() produce date only, CURTIME() display time only, we can use one of them according to our need with CAST or merge other calculation it, MySQL rich in these type of function.

NOTE:- You can see the difference using query select NOW() as NOWDATETIME, CURDATE() as NOWDATE, CURTIME() as NOWTIME ;

In my case I had to make a POST request, which had information sent through the header, and also a file sent using a FormData object.

I made it work using a combination of some of the answers here, so basically what ended up working was having this five lines in my Ajax request:

 contentType: "application/octet-stream",
 enctype: 'multipart/form-data',
 contentType: false,
 processData: false,
 data: formData,

Where formData was a variable created like this:

 var file = document.getElementById('uploadedFile').files[0];
 var form = $('form')[0];
 var formData = new FormData(form);
 formData.append("File", file);

Using Hadley Wickham's purrr package this is quite simple. Use split to split the passed data_frame into groups, then use map to apply the summary function to each group.

library(purrr)

df %>% split(.$group) %>% map(summary)

I tried to use onGlobalLayout() to do some custom formatting of a TextView, but as @George Bailey noticed, onGlobalLayout() is indeed called twice: once on the initial layout path, and second time after modifying the text.

View.onSizeChanged() works better for me because if I modify the text there, the method is called only once (during the layout pass). This required sub-classing of TextView, but on API Level 11+ View. addOnLayoutChangeListener() can be used to avoid sub-classing.

One more thing, in order to get correct width of the view in View.onSizeChanged(), the layout_width should be set to match_parent, not wrap_content.

According to the specification, http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-404.pdf:

A string is a sequence of Unicode code points wrapped with quotation marks (U+0022). All characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark (U+0022), reverse solidus (U+005C), and the control characters U+0000 to U+001F. There are two-character escape sequence representations of some characters.

So you can't pass 0x0A or 0x0C codes directly. It is forbidden! The specification suggests to use escape sequences for some well-defined codes from U+0000 to U+001F:

• \f represents the form feed character (U+000C).
• \n represents the line feed character (U+000A).

As most of programming languages uses \ for quoting, you should escape the escape syntax (double-escape - once for language/platform, once for JSON itself):

jsonStr = "{ \"name\": \"Multi\\nline.\" }";

preg_match('/'.preg_quote('^\'£$%^&*()}{@#~?><,@|-=-_+-¬', '/').'/', $string);

For example in GNU/Linux you can use:

Pid=$(pidof `process_name`)

if [ $Pid > 0 ]; then

   do something
else

   do something
fi 

Or something like

Pin=$(ps -A | grep name | awk 'print $4}')
echo $PIN

and that shows you the name of the app, just the name without ID.

I use very minimal, one page class implementation inspired by code from this blog post:

#import <mach/mach_time.h>

@interface DBGStopwatch : NSObject

+ (void)start:(NSString *)name;
+ (void)stop:(NSString *)name;

@end

@implementation DBGStopwatch

+ (NSMutableDictionary *)watches {
    static NSMutableDictionary *Watches = nil;
    static dispatch_once_t OnceToken;
    dispatch_once(&OnceToken, ^{
        Watches = @{}.mutableCopy;
    });
    return Watches;
}

+ (double)secondsFromMachTime:(uint64_t)time {
    mach_timebase_info_data_t timebase;
    mach_timebase_info(&timebase);
    return (double)time * (double)timebase.numer /
        (double)timebase.denom / 1e9;
}

+ (void)start:(NSString *)name {
    uint64_t begin = mach_absolute_time();
    self.watches[name] = @(begin);
}

+ (void)stop:(NSString *)name {
    uint64_t end = mach_absolute_time();
    uint64_t begin = [self.watches[name] unsignedLongLongValue];
    DDLogInfo(@"Time taken for %@ %g s",
              name, [self secondsFromMachTime:(end - begin)]);
    [self.watches removeObjectForKey:name];
}

@end

The usage of it is very simple:

• just call [DBGStopwatch start:@"slow-operation"]; at the beginning
• and then [DBGStopwatch stop:@"slow-operation"]; after the finish, to get the time

with open(destPath+'\\'+csvXML, 'a+') as csvFile:
    writer = csv.writer(csvFile, delimiter=';', lineterminator='\r')
    writer.writerows(xmlList)

The "lineterminator='\r'" permit to pass to next row, without empty row between two.

Hmm, I actually think I'm onto something (this is like the most interesting question ever - so it'd be a shame not to continue trying to find the "perfect" answer, even though an acceptable one has been found)...

Once you find the logo, your troubles are half done. Then you only have to figure out the differences between what's around the logo. Additionally, we want to do as little extra as possible. I think this is actually this easy part...

What is around the logo? For a can, we can see metal, which despite the effects of lighting, does not change whatsoever in its basic colour. As long as we know the angle of the label, we can tell what's directly above it, so we're looking at the difference between these:

Here, what's above and below the logo is completely dark, consistent in colour. Relatively easy in that respect.

Here, what's above and below is light, but still consistent in colour. It's all-silver, and all-silver metal actually seems pretty rare, as well as silver colours in general. Additionally, it's in a thin slither and close enough to the red that has already been identified so you could trace its shape for its entire length to calculate a percentage of what can be considered the metal ring of the can. Really, you only need a small fraction of that anywhere along the can to tell it is part of it, but you still need to find a balance that ensures it's not just an empty bottle with something metal behind it.

And finally, the tricky one. But not so tricky, once we're only going by what we can see directly above (and below) the red wrapper. Its transparent, which means it will show whatever is behind it. That's good, because things that are behind it aren't likely to be as consistent in colour as the silver circular metal of the can. There could be many different things behind it, which would tell us that it's an empty (or filled with clear liquid) bottle, or a consistent colour, which could either mean that it's filled with liquid or that the bottle is simply in front of a solid colour. We're working with what's closest to the top and bottom, and the chances of the right colours being in the right place are relatively slim. We know it's a bottle, because it hasn't got that key visual element of the can, which is relatively simplistic compared to what could be behind a bottle.

(that last one was the best I could find of an empty large coca cola bottle - interestingly the cap AND ring are yellow, indicating that the redness of the cap probably shouldn't be relied upon)

In the rare circumstance that a similar shade of silver is behind the bottle, even after the abstraction of the plastic, or the bottle is somehow filled with the same shade of silver liquid, we can fall back on what we can roughly estimate as being the shape of the silver - which as I mentioned, is circular and follows the shape of the can. But even though I lack any certain knowledge in image processing, that sounds slow. Better yet, why not deduce this by for once checking around the sides of the logo to ensure there is nothing of the same silver colour there? Ah, but what if there's the same shade of silver behind a can? Then, we do indeed have to pay more attention to shapes, looking at the top and bottom of the can again.

Depending on how flawless this all needs to be, it could be very slow, but I guess my basic concept is to check the easiest and closest things first. Go by colour differences around the already matched shape (which seems the most trivial part of this anyway) before going to the effort of working out the shape of the other elements. To list it, it goes:

• Find the main attraction (red logo background, and possibly the logo itself for orientation, though in case the can is turned away, you need to concentrate on the red alone)
• Verify the shape and orientation, yet again via the very distinctive redness
• Check colours around the shape (since it's quick and painless)
• Finally, if needed, verify the shape of those colours around the main attraction for the right roundness.

In the event you can't do this, it probably means the top and bottom of the can are covered, and the only possible things that a human could have used to reliably make a distinction between the can and the bottle is the occlusion and reflection of the can, which would be a much harder battle to process. However, to go even further, you could follow the angle of the can/bottle to check for more bottle-like traits, using the semi-transparent scanning techniques mentioned in the other answers.

Interesting additional nightmares might include a can conveniently sitting behind the bottle at such a distance that the metal of it just so happens to show above and below the label, which would still fail as long as you're scanning along the entire length of the red label - which is actually more of a problem because you're not detecting a can where you could have, as opposed to considering that you're actually detecting a bottle, including the can by accident. The glass is half empty, in that case!

As a disclaimer, I have no experience in nor have ever thought about image processing outside of this question, but it is so interesting that it got me thinking pretty deeply about it, and after reading all the other answers, I consider this to possibly be the easiest and most efficient way to get it done. Personally, I'm just glad I don't actually have to think about programming this!

EDIT

Additionally, look at this drawing I did in MS Paint... It's absolutely awful and quite incomplete, but based on the shape and colours alone, you can guess what it's probably going to be. In essence, these are the only things that one needs to bother scanning for. When you look at that very distinctive shape and combination of colours so close, what else could it possibly be? The bit I didn't paint, the white background, should be considered "anything inconsistent". If it had a transparent background, it could go over almost any other image and you could still see it.

Official FAQ ( https://reactjs.org/docs/hooks-faq.html#is-there-something-like-forceupdate ) now recommends this way if you really need to do it:

  const [ignored, forceUpdate] = useReducer(x => x + 1, 0);

  function handleClick() {
    forceUpdate();
  }

You can also do like this:

private void button2_Click(object sender, EventArgs e)
{
    System.Windows.Forms.Application.ExitThread();
}

As a learning exercise for myself, I created a class to be able to create several stopwatch timer instances that you might find useful (I'm sure there are better/simpler versions around in the time modules or similar)

import time as tm

    count = 0
    description = "Stopwatch class object (default description)"

        self.mode = 'init'
        self.starttime = 0.
        self.created = tm.strftime("%Y-%m-%d %H:%M:%S", tm.gmtime())
        Watch.count += 1

    def __call__(self):
        if self.mode == 'running':
            return tm.time() - self.starttime
        elif self.mode == 'stopped':
            return self.elapsed
        else:
            return 0.

    def display(self):

SQL-Server follows the principle of "Least Privilege" -- you must (explicitly) grant permissions.

'does it mean that they wont be able to update 4 and 5 ?'

If your users in the doctor role are only in the doctor role, then yes.

However, if those users are also in other roles (namely, other roles that do have access to 4 & 5), then no.

Might sound silly but I simply called npm i node-fetch --save in the wrong project. Make sure you are in the correct directory.

You can use routerLink in the following manner,

<input type="button" value="Add Bulk Enquiry" [routerLink]="['../addBulkEnquiry']" class="btn">

or use <button [routerLink]="['./url']"> in your case, for more info you could read the entire stacktrace on github https://github.com/angular/angular/issues/9471

the other methods are also correct but they create a dependency on the component file.

Hope your concern is resolved.

_bitmapScaled.compress() should do the trick. Check out the docs: http://developer.android.com/reference/android/graphics/Bitmap.html#compress(android.graphics.Bitmap.CompressFormat, int, java.io.OutputStream)

Yes you can.

You don't have to download both Anaconda.

Only you need to download one of the version of Anaconda and need activate other version of Anaconda python.

If you have Python 3, you can set up a Python 2 kernel like this;

python2 -m pip install ipykernel

python2 -m ipykernel install --user

If you have Python 2,

python3 -m pip install ipykernel

python3 -m ipykernel install --user

Then you will be able to see both version of Python!

If you are using Anaconda Spyder then you should swap version here:

If you are using Jupiter then check here:

Note: If your Jupiter or Anaconda already open after installation you need to restart again. Then you will be able to see.

If you are using jQuery you can do this:

$(function() {_x000D_
_x000D_
  var $list = $("#list");_x000D_
_x000D_
  $list.children().detach().sort(function(a, b) {_x000D_
    return $(a).text().localeCompare($(b).text());_x000D_
  }).appendTo($list);_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
_x000D_
<ul id="list">_x000D_
  <li>delta</li>_x000D_
  <li>cat</li>_x000D_
  <li>alpha</li>_x000D_
  <li>cat</li>_x000D_
  <li>beta</li>_x000D_
  <li>gamma</li>_x000D_
  <li>gamma</li>_x000D_
  <li>alpha</li>_x000D_
  <li>cat</li>_x000D_
  <li>delta</li>_x000D_
  <li>bat</li>_x000D_
  <li>cat</li>_x000D_
</ul>

Note that returning 1 and -1 (or 0 and 1) from the compare function is absolutely wrong.

As mentioned in the React documentation, there is no guarantee of setState being fired synchronously, so your console.log may return the state prior to it updating.

Michael Parker mentions passing a callback within the setState. Another way to handle the logic after state change is via the componentDidUpdate lifecycle method, which is the method recommended in React docs.

Generally we recommend using componentDidUpdate() for such logic instead.

This is particularly useful when there may be successive setStates fired, and you would like to fire the same function after every state change. Rather than adding a callback to each setState, you could place the function inside of the componentDidUpdate, with specific logic inside if necessary.

// example
componentDidUpdate(prevProps, prevState) {
  if (this.state.value > prevState.value) {
    this.foo();  
  }
}

If you want a histogram, you don't need to attach any 'names' to x-values, as on x-axis you would have data bins:

import matplotlib.pyplot as plt
import numpy as np
%matplotlib inline

np.random.seed(42)
x = np.random.normal(size=1000)

plt.hist(x, density=True, bins=30)  # density=False would make counts
plt.ylabel('Probability')
plt.xlabel('Data');

Note, the number of bins=30 was chosen arbitrarily, and there is Freedman–Diaconis rule to be more scientific in choosing the "right" bin width:

, where IQR is Interquartile range and n is total number of datapoints to plot

So, according to this rule one may calculate number of bins as:

q25, q75 = np.percentile(x,[.25,.75])
bin_width = 2*(q75 - q25)*len(x)**(-1/3)
bins = round((x.max() - x.min())/bin_width)
print("Freedman–Diaconis number of bins:", bins)
plt.hist(x, bins = bins);

Freedman–Diaconis number of bins: 82

And finally you can make your histogram a bit fancier with PDF line, titles, and legend:

import scipy.stats as st

plt.hist(x, density=True, bins=82, label="Data")
mn, mx = plt.xlim()
plt.xlim(mn, mx)
kde_xs = np.linspace(mn, mx, 300)
kde = st.gaussian_kde(x)
plt.plot(kde_xs, kde.pdf(kde_xs), label="PDF")
plt.legend(loc="upper left")
plt.ylabel('Probability')
plt.xlabel('Data')
plt.title("Histogram");

However, if you have limited number of data points, like in OP, a bar plot would make more sense to represent your data. Then you may attach labels to x-axis:

x = np.arange(3)
plt.bar(x, height=[1,2,3])
plt.xticks(x, ['a','b','c'])

This works for stdlib on Python 3.2 onwards (assuming all the timestamps are UTC):

from datetime import datetime, timezone, timedelta
datetime.strptime(timestamp, "%Y-%m-%dT%H:%M:%S.%fZ").replace(
    tzinfo=timezone(timedelta(0)))

For example,

>>> datetime.utcnow().replace(tzinfo=timezone(timedelta(0)))
... datetime.datetime(2015, 3, 11, 6, 2, 47, 879129, tzinfo=datetime.timezone.utc)

I've used HttpClient in .NET 4.0 applications on numerous occasions. If you are familiar with NuGet, you can do an Install-Package Microsoft.Net.Http to add it to your project. See the link below for further details.

http://nuget.org/packages/Microsoft.Net.Http

Multiple generic constraints can't be combined in an OR fashion (less restrictive), only in an AND fashion (more restrictive). Meaning that one method can't handle both scenarios. The generic constraints also cannot be used to make a unique signature for the method, so you'd have to use 2 separate method names.

However, you can use the generic constraints to make sure that the methods are used correctly.

In my case, I specifically wanted null to be returned, and never the default value of any possible value types. GetValueOrDefault = bad. GetValueOrNull = good.

I used the words "Null" and "Nullable" to distinguish between reference types and value types. And here is an example of a couple extension methods I wrote that compliments the FirstOrDefault method in System.Linq.Enumerable class.

    public static TSource FirstOrNull<TSource>(this IEnumerable<TSource> source)
        where TSource: class
    {
        if (source == null) return null;
        var result = source.FirstOrDefault();   // Default for a class is null
        return result;
    }

    public static TSource? FirstOrNullable<TSource>(this IEnumerable<TSource?> source)
        where TSource : struct
    {
        if (source == null) return null;
        var result = source.FirstOrDefault();   // Default for a nullable is null
        return result;
    }

Like this:

var str = 'Hello, World, etc';
var myarray = str.split(',');

for(var i = 0; i < myarray.length; i++)
{
   console.log(myarray[i]);
}

I've taken the OP's sproc and made it reusable and schema independent. Obviously it still requires MySQL 5.

When constructing a BigInteger with a string, the string must be formatted as a decimal number. You cannot use letters, unless you specify a radix in the second argument, you can specify up to 36 in the radix. 36 will give you alphanumeric characters only [0-9,a-z], so if you use this, you will have no formatting. You can create: new BigInteger("ihavenospaces", 36) Then to convert back, use a .toString(36)

BUT TO KEEP FORMATTING: Use the byte[] method that a couple people mentioned. That will pack the data with formatting into the smallest size, and allow you to keep track of number of bytes easily

That should be perfect for an RSA public key crypto system example program, assuming you keep the number of bytes in the message smaller than the number of bytes of PQ

_{This is now a multiple-year old question, but being very popular, it's worth mentioning a fantastic resource for learning about the C++11 memory model. I see no point in summing up his talk in order to make this yet another full answer, but given this is the guy who actually wrote the standard, I think it's well worth watching the talk.}

Herb Sutter has a three hour long talk about the C++11 memory model titled "atomic<> Weapons", available on the Channel9 site - part 1 and part 2. The talk is pretty technical, and covers the following topics:

1. Optimizations, Races, and the Memory Model
2. Ordering – What: Acquire and Release
3. Ordering – How: Mutexes, Atomics, and/or Fences
4. Other Restrictions on Compilers and Hardware
5. Code Gen & Performance: x86/x64, IA64, POWER, ARM
6. Relaxed Atomics

The talk doesn't elaborate on the API, but rather on the reasoning, background, under the hood and behind the scenes (did you know relaxed semantics were added to the standard only because POWER and ARM do not support synchronized load efficiently?).

I'm using AS 3.2.1, and was about to try some of the plugins, but was hesitant realizing the plugins are able to monitor any data..

It's actually really simple doing it via the Terminal tab in AS:

1. Turn on debugging over WiFi in your phone
   • Go to developer options and turn on "ADB over network"
   • You'll see the exact address and port to use when connecting
2. Go to the Terminal tab in Android Studio
3. Type adb tcpip 5555
4. Type your ip address as seen in developer options i.e. adb connect 192.168.1.101
5. Now you'll see your device in AS "Select deployment target" dialog

Found the answer, use android.support.design:hintTextAppearance attribute to set your own floating label appearance.

Example:

<android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:hintTextAppearance="@style/TextAppearance.AppCompat">

    <EditText
        android:id="@+id/password"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/prompt_password"/>
</android.support.design.widget.TextInputLayout>

You can directly import github projects into Android Studio. File -> New -> Project from Version Control -> GitHub. Then enter your github username and password.Select the repository and hit clone.

The github repo will be created as a new project in android studio.

These lines in your makefile,

INC_DIR = ../StdCUtil
CFLAGS=-c -Wall -I$(INC_DIR)
DEPS = split.h

and this line in your .cpp file,

#include "StdCUtil/split.h"

are in conflict.

With your makefile in your source directory and with that -I option you should be using #include "split.h" in your source file, and your dependency should be ../StdCUtil/split.h.

Another option:

INC_DIR = ../StdCUtil
CFLAGS=-c -Wall -I$(INC_DIR)/..  # Ugly!
DEPS = $(INC_DIR)/split.h

With this your #include directive would remain as #include "StdCUtil/split.h".

Yet another option is to place your makefile in the parent directory:

root
  |____Makefile
  |
  |___Core
  |     |____DBC.cpp
  |     |____Lock.cpp
  |     |____Trace.cpp
  |
  |___StdCUtil
        |___split.h

With this layout it is common to put the object files (and possibly the executable) in a subdirectory that is parallel to your Core and StdCUtil directories. Object, for example. With this, your makefile becomes:

INC_DIR = StdCUtil
SRC_DIR = Core
OBJ_DIR = Object
CFLAGS  = -c -Wall -I.
SRCS = $(SRC_DIR)/Lock.cpp $(SRC_DIR)/DBC.cpp $(SRC_DIR)/Trace.cpp
OBJS = $(OBJ_DIR)/Lock.o $(OBJ_DIR)/DBC.o $(OBJ_DIR)/Trace.o
# Note: The above will soon get unwieldy.
# The wildcard and patsubt commands will come to your rescue.

DEPS = $(INC_DIR)/split.h
# Note: The above will soon get unwieldy.
# You will soon want to use an automatic dependency generator.


all: $(OBJS)

$(OBJ_DIR)/%.o: $(SRC_DIR)/%.cpp
  $(CC) $(CFLAGS) -c $< -o $@

$(OBJ_DIR)/Trace.o: $(DEPS)

In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic about following the C++ standard), you can do:

int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++

If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:

int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!

Or, better yet, use a standard container:

int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>

If you still want a proper array, you can use a constant, not a variable, when creating it:

const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)

Similarly, if you want to get the size from a function in C++11, you can use a constexpr:

constexpr int n()
{
    return 10;
}

double a[n()]; // n() is a compile time constant expression

Seems like you just forgot the comma to separate the classes. So based on your configuration the following will work:

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration,\
    org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,\
    org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration,\
    org.springframework.boot.autoconfigure.data.web.SpringDataWebAutoConfiguration

Alternatively you could also define it as follow:

spring.autoconfigure.exclude[0]=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration
spring.autoconfigure.exclude[1]=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
spring.autoconfigure.exclude[2]=org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration
spring.autoconfigure.exclude[3]=org.springframework.boot.autoconfigure.data.web.SpringDataWebAutoConfiguration

Well, in Java an int is a primitive while an Integer is an Object. Meaning, if you made a new Integer:

Integer i = new Integer(6);

You could call some method on i:

String s = i.toString();//sets s the string representation of i

Whereas with an int:

int i = 6;

You cannot call any methods on it, because it is simply a primitive. So:

String s = i.toString();//will not work!!!

would produce an error, because int is not an object.

int is one of the few primitives in Java (along with char and some others). I'm not 100% sure, but I'm thinking that the Integer object more or less just has an int property and a whole bunch of methods to interact with that property (like the toString() method for example). So Integer is a fancy way to work with an int (Just as perhaps String is a fancy way to work with a group of chars).

I know that Java isn't C, but since I've never programmed in C this is the closest I could come to the answer. Hope this helps!

Setting JAVA_HOME directory from command line worked for me!

First:

JAVA_HOME="C:\Program Files\Java\jdk1.8.0"

Or :

export JAVA_HOME="C:\Program Files\Java\jdk1.8.0"

Then try:

mvn -version

to make sure you do not get the same error. :)

You should check for permissions in the following way (as described here Android permissions):

int result = ContextCompat.checkSelfPermission(getContext(), Manifest.permission.READ_PHONE_STATE);

then, compare your result to either:

result == PackageManager.PERMISSION_DENIED

or:

result == PackageManager.PERMISSION_GRANTED

None of these solutions seem to work if you increase the amount of text so it is larger than the width of the parent container, the element to the right still gets moved below the one to the left instead of remaining next to it. To fix this, you can apply this style to the left element:

position: absolute;
width: 50px;

And apply this style to the right element:

margin-left: 50px;

Just make sure that the margin-left for the right element is greater than or equal to the width of the left element. No floating or other attributes are necessary. I would suggest wrapping these elements in a div with the style:

display: inline-block;

Applying this style may not be necessary depending on surrounding elements

Fiddle: http://jsfiddle.net/2b0bqqse/

You can see the text to the right is taller than the element to the left outlined in black. If you remove the absolute positioning and margin and instead use float as others have suggested, the text to the right will drop down below the element to the left

Fiddle: http://jsfiddle.net/qrx78u20/

If you have two columns with the same name. One simple way is to manually rename the columns like this:-

df.columns = ['column1', 'column2', 'column3']

Then you can drop via column index as you requested, like this:-

df.drop(df.columns[1], axis=1, inplace=True)

df.column[1] will drop index 1.

Remember axis 1 = columns and axis 0 = rows.

Use mongoexport/mongoimport to dump/restore a collection:

Export JSON File:

mongoexport --db <database-name> --collection <collection-name> --out output.json

Import JSON File:

mongoimport --db <database-name> --collection <collection-name> --file input.json

WARNING mongoimport and mongoexport do not reliably preserve all rich BSON data types because JSON can only represent a subset of the types supported by BSON. As a result, data exported or imported with these tools may lose some measure of fidelity.

Also, http://bsonspec.org/

BSON is designed to be fast to encode and decode. For example, integers are stored as 32 (or 64) bit integers, so they don't need to be parsed to and from text. This uses more space than JSON for small integers, but is much faster to parse.

In addition to compactness, BSON adds additional data types unavailable in JSON, notably the BinData and Date data types.

It would help if you provided the error you are seeing. Look at http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html and you will see that max only returns the max between two numbers, so likely you code is not even compiling.

Solve all your compilation errors first.

Then your homework will consist of finding the max of three numbers by comparing the first two together, and comparing that max result with the third value. You should have enough to find your answer now.

In .net core 3.1 (and other more recent versions), you can use:

private readonly UserManager<IdentityUser> _userManager;

public ExampleController(UserManager<IdentityUser> userManager)
{
    _userManager = userManager;
}

Then:

string userId = _userManager.GetUserId(User);

Or async:

var user = await _userManager.GetUserAsync(User);
var userId = user.Id;

At this point, I'm trying to figure out why you'd use one over the other. I know the general benefits of async, but see both of these used frequently. Please post some comments if anyone knows.

I'm on macOS Catalina 10.15.3, and I had a similar error: ExecutableNotFound: failed to execute ['dot', '-Tsvg'], make sure the Graphviz executables are on your systems' PATH

Fixed it with:

pip3 install graphviz AND brew install graphviz

Note the pip3 install will only return the success message Successfully installed graphviz-0.13.2 so we still need to run brew install to get graphviz 2.42.3 (as of 10 Mar 2020, 6PM).

Try new_list = a[0:2] + [a[4]] + a[6:].

Or more generally, something like this:

from itertools import chain
new_list = list(chain(a[0:2], [a[4]], a[6:]))

This works with other sequences as well, and is likely to be faster.

Or you could do this:

def chain_elements_or_slices(*elements_or_slices):
    new_list = []
    for i in elements_or_slices:
        if isinstance(i, list):
            new_list.extend(i)
        else:
            new_list.append(i)
    return new_list

new_list = chain_elements_or_slices(a[0:2], a[4], a[6:])

But beware, this would lead to problems if some of the elements in your list were themselves lists. To solve this, either use one of the previous solutions, or replace a[4] with a[4:5] (or more generally a[n] with a[n:n+1]).

Solution 3

This is for using a single directory for multiple projects. I use this technique for some closely related projects where I often need to pull changes from one project into another. It's similar to the orphaned branches idea but the branches don't need to be orphaned. Simply start all the projects from the same empty directory state.

Start all projects from one committed empty directory

Don't expect wonders from this solution. As I see it, you are always going to have annoyances with untracked files. Git doesn't really have a clue what to do with them and so if there are intermediate files generated by a compiler and ignored by your .gitignore file, it is likely that they will be left hanging some of the time if you try rapidly swapping between - for example - your software project and a PH.D thesis project.

However here is the plan. Start as you ought to start any git projects, by committing the empty repository, and then start all your projects from the same empty directory state. That way you are certain that the two lots of files are fairly independent. Also, give your branches a proper name and don't lazily just use "master". Your projects need to be separate so give them appropriate names.

Git commits (and hence tags and branches) basically store the state of a directory and its subdirectories and Git has no idea whether these are parts of the same or different projects so really there is no problem for git storing different projects in the same repository. The problem is then for you clearing up the untracked files from one project when using another, or separating the projects later.

Create an empty repository

cd some_empty_directory
git init
touch .gitignore
git add .gitignore
git commit -m empty
git tag EMPTY

Start your projects from empty.

Work on one project.

git branch software EMPTY
git checkout software
echo "array board[8,8] of piece" > chess.prog

git add chess.prog 
git commit -m "chess program"

Start another project

whenever you like.

git branch thesis EMPTY
git checkout thesis
echo "the meaning of meaning" > philosophy_doctorate.txt
git add philosophy_doctorate.txt 
git commit -m "Ph.D"

Switch back and forth

Go back and forwards between projects whenever you like. This example goes back to the chess software project.

git checkout software
echo "while not end_of_game do make_move()" >> chess.prog
git add chess.prog 
git commit -m "improved chess program"

Untracked files are annoying

You will however be annoyed by untracked files when swapping between projects/branches.

touch untracked_software_file.prog
git checkout thesis 
ls
    philosophy_doctorate.txt  untracked_software_file.prog

It's not an insurmountable problem

Sort of by definition, git doesn't really know what to do with untracked files and it's up to you to deal with them. You can stop untracked files from being carried around from one branch to another as follows.

git checkout EMPTY 
ls
    untracked_software_file.prog
rm -r *
    (directory is now really empty, apart from the repository stuff!)
git checkout thesis
ls
    philosophy_doctorate.txt

By ensuring that the directory was empty before checking out our new project we made sure there were no hanging untracked files from another project.

A refinement

$ GIT_AUTHOR_DATE='2001-01-01:T01:01:01' GIT_COMMITTER_DATE='2001-01-01T01:01:01' git commit -m empty

If the same dates are specified whenever committing an empty repository, then independently created empty repository commits can have the same SHA1 code. This allows two repositories to be created independently and then merged together into a single tree with a common root in one repository later.

Example

# Create thesis repository. 
# Merge existing chess repository branch into it

mkdir single_repo_for_thesis_and_chess
cd single_repo_for_thesis_and_chess
git init
touch .gitignore
git add .gitignore
GIT_AUTHOR_DATE='2001-01-01:T01:01:01' GIT_COMMITTER_DATE='2001-01-01:T01:01:01' git commit -m empty
git tag EMPTY
echo "the meaning of meaning" > thesis.txt
git add thesis.txt
git commit -m "Wrote my PH.D"
git branch -m master thesis

# It's as simple as this ...
git remote add chess ../chessrepository/.git
git fetch chess chess:chess

Result

Use subdirectories per project?

It may also help if you keep your projects in subdirectories where possible, e.g. instead of having files

chess.prog
philosophy_doctorate.txt 

have

chess/chess.prog
thesis/philosophy_doctorate.txt 

In this case your untracked software file will be chess/untracked_software_file.prog. When working in the thesis directory you should not be disturbed by untracked chess program files, and you may find occasions when you can work happily without deleting untracked files from other projects.

Also, if you want to remove untracked files from other projects, it will be quicker (and less prone to error) to dump an unwanted directory than to remove unwanted files by selecting each of them.

Branch names can include '/' characters

So you might want to name your branches something like

project1/master
project1/featureABC
project2/master
project2/featureXYZ

You can do something like this:

.flex {_x000D_
  display: flex;_x000D_
  flex-direction: row;_x000D_
  flex-wrap: wrap;_x000D_
}_x000D_
_x000D_
.flex>div {_x000D_
  flex: 1 0 50%;_x000D_
}_x000D_
_x000D_
.flex>div:first-child {_x000D_
  flex: 0 1 100%;_x000D_
}

<div class="flex">_x000D_
  <div>Hi</div>_x000D_
  <div>Hello</div>_x000D_
  <div>Hello 2</div>_x000D_
</div>

Here is a demo: http://jsfiddle.net/73574emn/1/

This model relies on the line-wrap after one "row" is full. Since we set the first item's flex-basis to be 100% it fills the first row completely. Special attention on the flex-wrap: wrap;

import datetime
import pytz

# datetime object with timezone awareness:
datetime.datetime.now(tz=pytz.utc)

# seconds from epoch:
datetime.datetime.now(tz=pytz.utc).timestamp() 

# ms from epoch:
int(datetime.datetime.now(tz=pytz.utc).timestamp() * 1000) 

In PHP DateTime (PHP >= 5.3)

$dt = new DateTime();
$dt->setTimezone(new DateTimeZone('UTC'));
echo $dt->getTimestamp();

public class SomeClass
{
    public void SomeMethod()
    {
        StackFrame frame = new StackFrame(1);
        var method = frame.GetMethod();
        var type = method.DeclaringType;
        var name = method.Name;
    }
}

Now let's say you have another class like this:

public class Caller
{
   public void Call()
   {
      SomeClass s = new SomeClass();
      s.SomeMethod();
   }
}

name will be "Call" and type will be "Caller"

UPDATE Two years later since I'm still getting upvotes on this

In .Net 4.5 there is now a much easier way to do this. You can take advantage of the CallerMemberNameAttribute

Going with the previous example:

public class SomeClass
{
    public void SomeMethod([CallerMemberName]string memberName = "")
    {
        Console.WriteLine(memberName); //output will be name of calling method
    }
}

What you are looking to do is get the position using the LocationManager.NETWORK_PROVIDER instead of LocationManager.GPS_PROVIDER. The NETWORK_PROVIDER will resolve on the GSM or wifi, which ever available. Obviously with wifi off, GSM will be used. Keep in mind that using the cell network is accurate to basically 500m.

http://developer.android.com/guide/topics/location/obtaining-user-location.html has some really great information and sample code.

After you get done with most of the code in OnCreate(), add this:

// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
      // Called when a new location is found by the network location provider.
      makeUseOfNewLocation(location);
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {}

    public void onProviderEnabled(String provider) {}

    public void onProviderDisabled(String provider) {}
  };

// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

You could also have your activity implement the LocationListener class and thus implement onLocationChanged() in your activity.

regex: /^[a-zA-Z0-9_.]$/i

This works

business = Business.where(:user_id => current_user.id).first
if business.nil?
# no business found
else
# business.ceo = "me"
end

I found your article on the following page, which contains a number of references for PHP date time calculations.

Calculate the difference between two Dates (and time) using PHP. The following page provides a range of different methods (7 in total) for performing date / time calculations using PHP, to determine the difference in time (hours, munites), days, months or years between two dates.

See PHP Date Time – 7 Methods to Calculate the Difference between 2 dates.

Here's my bash implementation (with bits taken from other SO ;-)

function countTimeDiff() {
    timeA=$1 # 09:59:35

Not tested, may be buggy.

Just add like this in case 1: like this

 case 0:
     list = DBAdpter.requestUserData(assosiatetoken);
     Collections.sort(list, byDate);
     for (int i = 0; i < list.size(); i++) {
         if (list.get(i).lastModifiedDate != null) {
             lv.setAdapter(new MyListAdapter(
                     getApplicationContext(), list));
         }
     }
     break;

and put this method at end of the your class

static final Comparator<All_Request_data_dto> byDate = new Comparator<All_Request_data_dto>() {
    SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss a");

    public int compare(All_Request_data_dto ord1, All_Request_data_dto ord2) {
        Date d1 = null;
        Date d2 = null;
        try {
            d1 = sdf.parse(ord1.lastModifiedDate);
            d2 = sdf.parse(ord2.lastModifiedDate);
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


        return (d1.getTime() > d2.getTime() ? -1 : 1);     //descending
    //  return (d1.getTime() > d2.getTime() ? 1 : -1);     //ascending
    }
};

You could use a regular expression validator on the upload control:

  <asp:RegularExpressionValidator id="FileUpLoadValidator" runat="server" ErrorMessage="Upload Excel files only." ValidationExpression="^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))(.xls|.XLS|.xlsx|.XLSX)$" ControlToValidate="fileUpload"> </asp:RegularExpressionValidator>

There is also the accept attribute of the input tag:

<input type="file" accept="application/msexcel" id="fileUpload" runat="server">

but I did not have much success when I tried this (with FF3 and IE7)

if you open localhost/phpmyadmin you will find a tab called "User accounts". There you can define all your users that can access the mysql database, set their rights and even limit from where they can connect.

I'm working with zip files which Java's ZipFile class isn't able to handle. Java 8 apparently can't handle compression method 12 (bzip2 I believe). After trying a number of methods including zip4j (which also fails with these particular files due to another issue), I had success with Apache's commons-compress which supports additional compression methods as mentioned here.

Note that the ZipFile class below is not the one from java.util.zip.

It's actually org.apache.commons.compress.archivers.zip.ZipFile so be careful with the imports.

try (ZipFile zipFile = new ZipFile(archiveFile)) {
    Enumeration<ZipArchiveEntry> entries = zipFile.getEntries();
    while (entries.hasMoreElements()) {
        ZipArchiveEntry entry = entries.nextElement();
        File entryDestination = new File(destination, entry.getName());
        if (entry.isDirectory()) {
            entryDestination.mkdirs();
        } else {
            entryDestination.getParentFile().mkdirs();
            try (InputStream in = zipFile.getInputStream(entry); OutputStream out = new FileOutputStream(entryDestination)) {
                IOUtils.copy(in, out);
            }
        }
    }
} catch (IOException ex) {
    log.debug("Error unzipping archive file: " + archiveFile, ex);
}

For Gradle:

compile 'org.apache.commons:commons-compress:1.18'

This worked for me

FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        if(tag.equalsIgnoreCase("dashboard")){

            DashboardFragment dashboardFragment = (DashboardFragment)
                    fragmentManager.findFragmentByTag("dashboard");
            if(dashboardFragment!=null) ft.show(dashboardFragment);

            ShowcaseFragment showcaseFragment = (ShowcaseFragment)
                    fragmentManager.findFragmentByTag("showcase");
            if(showcaseFragment!=null) ft.hide(showcaseFragment);

        } else if(tag.equalsIgnoreCase("showcase")){
            DashboardFragment dashboardFragment = (DashboardFragment)
                    fragmentManager.findFragmentByTag("dashboard");
            if(dashboardFragment!=null) ft.hide(dashboardFragment);

            ShowcaseFragment showcaseFragment = (ShowcaseFragment)
                    fragmentManager.findFragmentByTag("showcase");
            if(showcaseFragment!=null) ft.show(showcaseFragment);
        }

        ft.commit();

net stop <your service> && net start <your service>

No net restart, unfortunately.

You can use FindIndex

 var index = Array.FindIndex(myArray, row => row.Author == "xyz");

Edit: I see you have an array of string, you can use any code to match, here an example with a simple contains:

 var index = Array.FindIndex(myArray, row => row.Contains("Author='xyz'"));

Maybe you need to match using a regular expression?

    import os
    os.mkdir('directory name') #### this command for creating directory
    os.mknod('file name') #### this for creating files
    os.system('touch filename') ###this is another method for creating file by using unix commands in os modules 

MySQL says:

All integer types can have an optional (nonstandard) attribute UNSIGNED. Unsigned type can be used to permit only nonnegative numbers in a column or when you need a larger upper numeric range for the column. For example, if an INT column is UNSIGNED, the size of the column's range is the same but its endpoints shift from -2147483648 and 2147483647 up to 0 and 4294967295.

When do I use it ?

Ask yourself this question: Will this field ever contain a negative value?
If the answer is no, then you want an UNSIGNED data type.

A common mistake is to use a primary key that is an auto-increment INT starting at zero, yet the type is SIGNED, in that case you’ll never touch any of the negative numbers and you are reducing the range of possible id's to half.

You would naturally use Integer#to_s(2), String#to_i(2) or "%b" in a real program, but, if you're interested in how the translation works, this method calculates the binary representation of a given integer using basic operators:

def int_to_binary(x)
  p = 0
  two_p = 0
  output = ""

  while two_p * 2 <= x do
    two_p = 2 ** p
    output << ((two_p & x == two_p) ? "1" : "0")
    p += 1
  end

  #Reverse output to match the endianness of %b
  output.reverse
end

To check it works:

1.upto(1000) do |n|
  built_in, custom = ("%b" % n), int_to_binary(n)
  if built_in != custom
    puts "I expected #{built_in} but got #{custom}!"
    exit 1
  end
  puts custom
end

Better still (or shorter anyway):

SUM(ccc_news_comments.id = 'approved')

This works since the Boolean type in MySQL is represented as INT 0 and 1, just like in C. (May not be portable across DB systems though.)

As for COALESCE() as mentioned in other answers, many language APIs automatically convert NULL to '' when fetching the value. For example with PHP's mysqli interface it would be safe to run your query without COALESCE().

Not exactly a packaging of the Python code, but there is now also Grumpy from Google, which transpiles the code to Go.

It doesn't support the Python C API, so it may not work for all projects.

To compare two lists with the order preserved use,

assertThat(actualList, contains("item1","item2"));

If your query consists only of the $where operator, you can pass in just the JavaScript expression:

db.T.find("this.Grade1 > this.Grade2");

For greater performance, run an aggregate operation that has a $redact pipeline to filter the documents which satisfy the given condition.

The $redact pipeline incorporates the functionality of $project and $match to implement field level redaction where it will return all documents matching the condition using $$KEEP and removes from the pipeline results those that don't match using the $$PRUNE variable.

Running the following aggregate operation filter the documents more efficiently than using $where for large collections as this uses a single pipeline and native MongoDB operators, rather than JavaScript evaluations with $where, which can slow down the query:

db.T.aggregate([
    {
        "$redact": {
            "$cond": [
                { "$gt": [ "$Grade1", "$Grade2" ] },
                "$$KEEP",
                "$$PRUNE"
            ]
        }
    }
])

which is a more simplified version of incorporating the two pipelines $project and $match:

db.T.aggregate([
    {
        "$project": {
            "isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] },
            "Grade1": 1,
            "Grade2": 1,
            "OtherFields": 1,
            ...
        }
    },
    { "$match": { "isGrade1Greater": 1 } }
])

With MongoDB 3.4 and newer:

db.T.aggregate([
    {
        "$addFields": {
            "isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] }
        }
    },
    { "$match": { "isGrade1Greater": 1 } }
])

If you happen to be using a mac keyboard on linux (ubuntu), Insert is actually fn + return. You can also click on the zero of the number pad to switch between the cursor types.

Took me a while to figure that out. :-P

Some counterpoints from the author:

You are stuck if you need to make the class not single in the future Not at all - I was in this situation with a single database connection singleton that I wanted to turn into a connection pool. Remember that every singleton is accessed through a standard method:

MyClass.instance

This is similar to the signature of a factory method. All I did was update the instance method to return the next connection from the pool - no other changes required. That would have been far harder if we had NOT been using a singleton.

Singletons are just fancy globals Can't argue with that but so are all static fields and methods - anything that is accessed from the class rather than an instance is essentially global and I dont see so much pushback on the use of static fields?

Not saying that Singletons are good, just pushing back at some of the 'conventional wisdom' here.

#FACTS.

application because .js-Files aren't something a user wants to read but something that should get executed.

This thread seems to answer your question : simultaneous-read-write-a-file

Basically, what you need is to declare two FileStream, one for read operations, the other for write operations. Writer Filestream needs to open your file in 'Append' mode.

you could try this:

I have these two columns (column "A" and column "B"). I want to color them when the values between cells in the same row mismatch.

Follow these steps:

1. Select the elements in column "A" (excluding A1);

2. Click on "Conditional formatting -> New Rule -> Use a formula to determine which cells to format";

3. Insert the following formula: =IF(A2<>B2;1;0);

4. Select the format options and click "OK";

5. Select the elements in column "B" (excluding B1) and repeat the steps from 2 to 4.

They mean different things. If you use var the variable is declared within the scope you are in (e.g. of the function). If you don't use var, the variable bubbles up through the layers of scope until it encounters a variable by the given name or the global object (window, if you are doing it in the browser), where it then attaches. It is then very similar to a global variable. However, it can still be deleted with delete (most likely by someone else's code who also failed to use var). If you use var in the global scope, the variable is truly global and cannot be deleted.

This is, in my opinion, one of the most dangerous issues with javascript, and should be deprecated, or at least raise warnings over warnings. The reason is, it's easy to forget var and have by accident a common variable name bound to the global object. This produces weird and difficult to debug behavior.

This is something I'd use the LAG function for:

SELECT eh.gc_staff_number,
       eh.start_date,
       LAG(eh.end_date) OVER (PARTITION BY eh.gc_staff_number
                                  ORDER BY eh.end_date) AS prev_end_date
  FROM EMPLOYMENT_HISTORY eh
 WHERE eh.current_flag = 'Y'

If you wanted to peek a row ahead, you'd use the LEAD function.

Compatibility:

To my knowledge, this is supported 9i+ but I haven't confirmed that 8i is supported like the documentation claims.

LEAD and LAG are finally ANSI, but only Oracle and PostgreSQL v8.4+ support them currently.

When you free that handle, the garbage collector is free to move the memory that was pinned. If you have a pointer to memory that's supposed to be pinned, and you un-pin that memory, then all bets are off. That this worked at all in 3.5 was probably just by luck. The JIT compiler and the runtime for 4.0 probably do a better job of object lifetime analysis.

If you really want to do this, you can use a try/finally to prevent the object from being un-pinned until after you've used it:

public static string Get(object a)
{
    GCHandle handle = GCHandle.Alloc(a, GCHandleType.Pinned);
    try
    {
        IntPtr pointer = GCHandle.ToIntPtr(handle);
        return "0x" + pointer.ToString("X");
    }
    finally
    {
        handle.Free();
    }
}

Here's an old discussion thread where I listed the main differences and the conditions in which you should use each of these methods. I think you may find it useful to go through the discussion.

To explain the differences as relevant to your posted example:

a. When you use RegisterStartupScript, it will render your script after all the elements in the page (right before the form's end tag). This enables the script to call or reference page elements without the possibility of it not finding them in the Page's DOM.

Here is the rendered source of the page when you invoke the RegisterStartupScript method:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
    <form name="form1" method="post" action="StartupScript.aspx" id="form1">
        <div>
            <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
        </div>
        <div> <span id="lblDisplayDate">Label</span>
            <br />
            <input type="submit" name="btnPostback" value="Register Startup Script" id="btnPostback" />
            <br />
            <input type="submit" name="btnPostBack2" value="Register" id="btnPostBack2" />
        </div>
        <div>
            <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="someViewstategibberish" />
        </div>
        <!-- Note this part -->
        <script language='javascript'>
            var lbl = document.getElementById('lblDisplayDate');
            lbl.style.color = 'red';
        </script>
    </form>
    <!-- Note this part -->
</body>
</html>

b. When you use RegisterClientScriptBlock, the script is rendered right after the Viewstate tag, but before any of the page elements. Since this is a direct script (not a function that can be called, it will immediately be executed by the browser. But the browser does not find the label in the Page's DOM at this stage and hence you should receive an "Object not found" error.

Here is the rendered source of the page when you invoke the RegisterClientScriptBlock method:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
    <form name="form1" method="post" action="StartupScript.aspx" id="form1">
        <div>
            <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
        </div>
        <script language='javascript'>
            var lbl = document.getElementById('lblDisplayDate');
            // Error is thrown in the next line because lbl is null.
            lbl.style.color = 'green';

Therefore, to summarize, you should call the latter method if you intend to render a function definition. You can then render the call to that function using the former method (or add a client side attribute).

Edit after comments:

For instance, the following function would work:

protected void btnPostBack2_Click(object sender, EventArgs e) 
{ 
  System.Text.StringBuilder sb = new System.Text.StringBuilder(); 
  sb.Append("<script language='javascript'>function ChangeColor() {"); 
  sb.Append("var lbl = document.getElementById('lblDisplayDate');"); 
  sb.Append("lbl.style.color='green';"); 
  sb.Append("}</script>"); 

  //Render the function definition. 
  if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock")) 
  {
    ClientScript.RegisterClientScriptBlock(this.GetType(), "JSScriptBlock", sb.ToString()); 
  }

  //Render the function invocation. 
  string funcCall = "<script language='javascript'>ChangeColor();</script>"; 

  if (!ClientScript.IsStartupScriptRegistered("JSScript"))
  { 
    ClientScript.RegisterStartupScript(this.GetType(), "JSScript", funcCall); 
  } 
} 

I had the same problem. Wound up just writing a custom highlight and unhighlight function for the validator. Adding this to the validaton options should add the error class to the element and its respective label:

        'highlight': function (element, errorClass, validClass) {
            if($(element).attr('type') == 'radio'){
                $(element.form).find("input[type=radio]").each(function(which){
                    $(element.form).find("label[for=" + this.id + "]").addClass(errorClass);
                    $(this).addClass(errorClass);
                });
            } else {
                $(element.form).find("label[for=" + element.id + "]").addClass(errorClass);
                $(element).addClass(errorClass);
            }
        },
        'unhighlight': function (element, errorClass, validClass) {
            if($(element).attr('type') == 'radio'){
                $(element.form).find("input[type=radio]").each(function(which){
                    $(element.form).find("label[for=" + this.id + "]").removeClass(errorClass);
                    $(this).removeClass(errorClass);
                });
            }else {
                $(element.form).find("label[for=" + element.id + "]").removeClass(errorClass);
                $(element).removeClass(errorClass);
            }
        },

you can use mongo query like this yearMonthDayhms: { $dateToString: { format: "%Y-%m-%d-%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}

HourMinute: { $dateToString: { format: "%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}

.SILENT:

You have to pass the arguments in the terminal in order to store them in 'argv'. This variable holds the arguments you pass to your Python script when you run it. It later unpacks the arguments and store them in different variables you specify in the program e.g.

script, first, second = argv
print "Your file is:", script
print "Your first entry is:", first
print "Your second entry is:" second

Then in your command line you have to run your code like this,

$python ex14.py Hamburger Pizza

Your output will look like this:

Your file is: ex14.py
Your first entry is: Hamburger
Your second entry is: Pizza

More importantly, the 2013 versions of Visual Studio Express have all the languages that comes with the commercial versions. You can use the Windows desktop versions not only to program using Windows Forms, it is possible to write those windowed applications with any language that comes with the software, may it be C++ using the windows.h header if you want to actually learn how to create windows applications from scratch, or use Windows form to create windows in C# or visual Basic.

In the past, you had to download one version for each language or type of content. Or just download an all-in-one that still installed separate versions of the software for different languages. Now with 2013 you get all the languages needed in each content oriented version of the 2013 express.

You pick what matters the most to you.

Besides, it might be a good way to learn using notepad and the command line to write and compile, but I find that a bit tedious to use. While using an IDE might be overwhelming at first, you start small, learning how to create a project, write code, compile your code. They have gone way over their heads to ease up your day when you take it for the first time.

While it isn't optimal for all operations, if you are making map tiles or working with large numbers of markers (dots) with only one projection (e.g. Mercator, like Google Maps and many other slippy maps frameworks expect), I have found what I call "Vast Coordinate System" to be really, really handy. Basically, you store x and y pixel coordinates at some way-zoomed-in -- I use zoom level 23. This has several benefits:

• You do the expensive lat/lng to mercator pixel transformation once instead of every time you handle the point
• Getting the tile coordinate from a record given a zoom level takes one right shift.
• Getting the pixel coordinate from a record takes one right shift and one bitwise AND.
• The shifts are so lightweight that it is practical to do them in SQL, which means you can do a DISTINCT to return only one record per pixel location, which will cut down on the number records returned by the backend, which means less processing on the front end.

I talked about all this in a recent blog post: http://blog.webfoot.com/2013/03/12/optimizing-map-tile-generation/

You can consider using numpy.putmask:

np.putmask(arr, arr>=T, 255.0)

Here is a performance comparison with the Numpy's builtin indexing:

In [1]: import numpy as np
In [2]: A = np.random.rand(500, 500)

In [3]: timeit np.putmask(A, A>0.5, 5)
1000 loops, best of 3: 1.34 ms per loop

In [4]: timeit A[A > 0.5] = 5
1000 loops, best of 3: 1.82 ms per loop

    header("Content-Disposition: attachment; filename=\"".basename($fullPath)."\";" );
    header("Content-Transfer-Encoding: binary");
    header("Content-Length: ".$fsize);
    ob_clean();
    flush();
    readfile( $fullPath );

  } else
    die('File Not Found');

}

Note :

From API Level 26, you also don't need to specifically cast the result of findViewById as it uses inference for its return type.

So now you can simply do,

public View onCreateView(LayoutInflater inflater, 
                         ViewGroup container, 
                         Bundle savedInstanceState) {
     View view = inflater.inflate(R.layout.testclassfragment, container, false);
     ImageView imageView =  view.findViewById(R.id.my_image); //without casting the return type
     return view;
}

With Swift 5, according to your needs, you may choose one of the four following Playground code examples in order to solve your problem.

#1. Using ClosedRange reversed() method

ClosedRange has a method called reversed(). reversed() method has the following declaration:

func reversed() -> ReversedCollection<ClosedRange<Bound>>

Returns a view presenting the elements of the collection in reverse order.

Usage:

let reversedCollection = (0 ... 5).reversed()

for index in reversedCollection {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

As an alternative, you can use Range reversed() method:

let reversedCollection = (0 ..< 6).reversed()

for index in reversedCollection {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

#2. Using sequence(first:next:) function

Swift Standard Library provides a function called sequence(first:next:). sequence(first:next:) has the following declaration:

func sequence<T>(first: T, next: @escaping (T) -> T?) -> UnfoldFirstSequence<T>

Returns a sequence formed from first and repeated lazy applications of next.

Usage:

let unfoldSequence = sequence(first: 5, next: {
    $0 > 0 ? $0 - 1 : nil
})

for index in unfoldSequence {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

#3. Using stride(from:through:by:) function

Swift Standard Library provides a function called stride(from:through:by:). stride(from:through:by:) has the following declaration:

func stride<T>(from start: T, through end: T, by stride: T.Stride) -> StrideThrough<T> where T : Strideable

Returns a sequence from a starting value toward, and possibly including, an end value, stepping by the specified amount.

Usage:

let sequence = stride(from: 5, through: 0, by: -1)

for index in sequence {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

As an alternative, you can use stride(from:to:by:):

let sequence = stride(from: 5, to: -1, by: -1)

for index in sequence {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

#4. Using AnyIterator init(_:) initializer

AnyIterator has an initializer called init(_:). init(_:) has the following declaration:

init(_ body: @escaping () -> AnyIterator<Element>.Element?)

Creates an iterator that wraps the given closure in its next() method.

Usage:

var index = 5

guard index >= 0 else { fatalError("index must be positive or equal to zero") }

let iterator = AnyIterator({ () -> Int? in
    defer { index = index - 1 }
    return index >= 0 ? index : nil
})

for index in iterator {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

If needed, you can refactor the previous code by creating an extension method for Int and wrapping your iterator in it:

extension Int {

    func iterateDownTo(_ endIndex: Int) -> AnyIterator<Int> {
        var index = self
        guard index >= endIndex else { fatalError("self must be greater than or equal to endIndex") }

        let iterator = AnyIterator { () -> Int? in
            defer { index = index - 1 }
            return index >= endIndex ? index : nil
        }
        return iterator
    }

}

let iterator = 5.iterateDownTo(0)

for index in iterator {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

flask.redirect(location, code=302)

Use "which searchstr". Returns either the path of the binary or the alias setup if it's an alias

Edit: If you're looking for a list of aliases, you can use:

alias -p | cut -d= -f1 | cut -d' ' -f2

Add that in to whichever PATH searching answer you like. Assumes you're using bash..

Adding disply:flex property to the label will get the job done!

UPDATE databaseName.tableName
SET columnName = replace(columnName, '?', '''')
WHERE columnName LIKE '%?%'

The other solution proposed on this page are useful some versions of Cmake < 3.3.2. Here the solution for the version I am using (i.e., 3.3.2). Check the version of your Cmake by using $ cmake --version and pick the solution that fits with your needs. The cmake documentation can be found on the official page.

With CMake version 3.3.2, in order to create

#define foo

I needed to use:

add_definitions(-Dfoo)   # <--------HERE THE NEW CMAKE LINE inside CMakeLists.txt
add_executable( ....)
target_link_libraries(....)

and, in order to have a preprocessor macro definition like this other one:

#define foo=5

the line is so modified:

add_definitions(-Dfoo=5)   # <--------HERE THE NEW CMAKE LINE inside CMakeLists.txt
add_executable( ....)
target_link_libraries(....)

if you have Firebug installed on Firefox, just open the url. In the network panel, right-click and select Copy as cURL. You can see all curl parameters for this web call.

You can use serialize() like this:

$.ajax({
  cache: false,
  url: 'test.php',
  data: $('form').serialize(),
  datatype: 'json',
  success: function(data) {

  }
});

Use mount (--mount) instead volume (-v)

More info: https://docs.docker.com/storage/bind-mounts/

Example:

Ensure /tmp/a.txt exists on docker host

docker run -it --mount type=bind,source=/tmp/a.txt,target=/root/a.txt alpine sh

This one $("#yourDiv").load(" #yourDiv > *"); is the best if you are planning to just reload a <div>

Make sure to use an id and not a class. Also, remember to paste <script src="https://code.jquery.com/jquery-3.5.1.js"></script> in the <head> section of the html file, if you haven't already. In opposite case it won't work.

Otherwise, you have function alpha in package scales in which you can directly input your vector of colors (even if they are factors as in your example):

library(scales)
cols <- cut(z, 6, labels = c("pink", "red", "yellow", "blue", "green", "purple"))
plot(x, y, main= "Fragment recruitment plot - FR-HIT", 
     ylab = "Percent identity", xlab = "Base pair position", 
     col = alpha(cols, 0.4), pch=16) 
# For an alpha of 0.4, i. e. an opacity of 40%.
