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!

Note that in order to create a so called "feature module", you need to import CommonModule inside it. So, your module initialization code will look like this:

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { TaskCardComponent } from './task-card/task-card.component';
import { MdCardModule } from '@angular2-material/card';

@NgModule({
  imports: [
    CommonModule,
    MdCardModule 
  ],
  declarations: [
    TaskCardComponent
  ],
  exports: [
    TaskCardComponent
  ]
})
export class TaskModule { }

The latest as of release of API 23 is

One solution would be to pipe your command from PowerShell to CMD. Running the following command will pipe the notepad.exe command over to CMD, which will then open the Notepad application.

PS C:\> "notepad.exe" | cmd

Once the command has run in CMD, you will be returned to a PowerShell prompt, and can continue running your PowerShell script.

CMD's Startup Message is Shown

As mklement0 points out, this method shows CMD's startup message. If you were to copy the output using the method above into another terminal, the startup message will be copied along with it.

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);

I was facing the same issue and in my case compiler compliance level was selected as 14 in my eclipse settings. In order to fix it, I changed it to the version of JDK on my machine i.e 1.8 and recompiled the project.

As per the SLF4J Error Codes

Failed to load class org.slf4j.impl.StaticLoggerBinder This warning message is reported when the org.slf4j.impl.StaticLoggerBinder class could not be loaded into memory. This happens when no appropriate SLF4J binding could be found on the class path. Placing one (and only one) of slf4j-nop.jar slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem.

Note that slf4j-api versions 2.0.x and later use the ServiceLoader mechanism. Backends such as logback 1.3 and later which target slf4j-api 2.x, do not ship with org.slf4j.impl.StaticLoggerBinder. If you place a logging backend which targets slf4j-api 2.0.x, you need slf4j-api-2.x.jar on the classpath. See also relevant faq entry.

SINCE 1.6.0 As of SLF4J version 1.6, in the absence of a binding, SLF4J will default to a no-operation (NOP) logger implementation.

If you are responsible for packaging an application and do not care about logging, then placing slf4j-nop.jar on the class path of your application will get rid of this warning message. Note that embedded components such as libraries or frameworks should not declare a dependency on any SLF4J binding but only depend on slf4j-api. When a library declares a compile-time dependency on a SLF4J binding, it imposes that binding on the end-user, thus negating SLF4J's purpose.

I've been using this in an Xcode JNI project to recursively build my test classes:

find ${PROJECT_DIR} -name "*.java" -print | xargs javac -g -classpath ${BUILT_PRODUCTS_DIR} -d ${BUILT_PRODUCTS_DIR}

I couldn't figure out how to use the API using the first Google results. Fortunately a thread somewhere pointed me to this link: http://access.mvps.org/access/api/api0049.htm

Which works nicely. :)

I found an following official matplotlib example that uses host_subplot to display multiple y-axes and all the different labels in one legend. No workaround necessary. Best solution I found so far. http://matplotlib.org/examples/axes_grid/demo_parasite_axes2.html

from mpl_toolkits.axes_grid1 import host_subplot
import mpl_toolkits.axisartist as AA
import matplotlib.pyplot as plt

host = host_subplot(111, axes_class=AA.Axes)
plt.subplots_adjust(right=0.75)

par1 = host.twinx()
par2 = host.twinx()

offset = 60
new_fixed_axis = par2.get_grid_helper().new_fixed_axis
par2.axis["right"] = new_fixed_axis(loc="right",
                                    axes=par2,
                                    offset=(offset, 0))

par2.axis["right"].toggle(all=True)

host.set_xlim(0, 2)
host.set_ylim(0, 2)

host.set_xlabel("Distance")
host.set_ylabel("Density")
par1.set_ylabel("Temperature")
par2.set_ylabel("Velocity")

p1, = host.plot([0, 1, 2], [0, 1, 2], label="Density")
p2, = par1.plot([0, 1, 2], [0, 3, 2], label="Temperature")
p3, = par2.plot([0, 1, 2], [50, 30, 15], label="Velocity")

par1.set_ylim(0, 4)
par2.set_ylim(1, 65)

host.legend()

plt.draw()
plt.show()

Some more explanations to the solution Rachel already gave:

"WPF Apps With The Model-View-ViewModel Design Pattern"

by Josh Smith

http://msdn.microsoft.com/en-us/magazine/dd419663.aspx

The solution seems to be to add multiple @font-face rules, for example:

@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans.ttf");
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Bold.ttf");
    font-weight: bold;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: italic, oblique;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic, oblique;
}

By the way, it would seem Google Chrome doesn't know about the format("ttf") argument, so you might want to skip that.

(This answer was correct for the CSS 2 specification. CSS3 only allows for one font-style rather than a comma-separated list.)

For C++, I suggest Accelerated C++ by Koenig and Moo as a beginning text, though I don't know how it would be for an absolute novice. It focuses on using the STL right away, which makes getting things done much easier.

Intersection Observer can be the best thing IMO, without any external library it does a really good job.

const options = {
            root: null,
            threshold: 0.25, // 0 - 1 this work as a trigger. 
            rootMargin: '150px'
        };

        const target = document.querySelector('h1#scroll-to');
        const observer = new IntersectionObserver(
           entries => { // each entry checks if the element is the view or not and if yes trigger the function accordingly
            entries.forEach(() => {
                alert('you have scrolled to the h1!')
            });
        }, options);
        observer.observe(target);

If your error event handler takes the three arguments (xmlhttprequest, textstatus, and message) when a timeout happens, the status arg will be 'timeout'.

Per the jQuery documentation:

Possible values for the second argument (besides null) are "timeout", "error", "notmodified" and "parsererror".

You can handle your error accordingly then.

I created this fiddle that demonstrates this.

$.ajax({
    url: "/ajax_json_echo/",
    type: "GET",
    dataType: "json",
    timeout: 1000,
    success: function(response) { alert(response); },
    error: function(xmlhttprequest, textstatus, message) {
        if(textstatus==="timeout") {
            alert("got timeout");
        } else {
            alert(textstatus);
        }
    }
});?

With jsFiddle, you can test ajax calls -- it will wait 2 seconds before responding. I put the timeout setting at 1 second, so it should error out and pass back a textstatus of 'timeout' to the error handler.

Hope this helps!

set -e stops the execution of a script if a command or pipeline has an error - which is the opposite of the default shell behaviour, which is to ignore errors in scripts. Type help set in a terminal to see the documentation for this built-in command.

Had the same issue that the client_max_body_size directive was ignored.

My silly error was, that I put a file inside /etc/nginx/conf.d which did not end with .conf. Nginx will not load these by default.

To anyone else who finds this older question, you can now download all old versions.

Xcode -> Preferences -> Components (Click on Simulators tab).

Install all the versions you want/need.

To show all installed simulators:

Target -> In dropdown "deployment target" choose the installed version with lowest version nr.

You should now see all your available simulators in the dropdown.

See The Bash Manual under 3.4.2 Special Parameters:

? - Expands to the exit status of the most recently executed foreground pipeline.

It is a little hard to find because it is not listed as $? (the variable name is "just" ?). Also see the exit status section, of course ;-)

Happy coding.

We show up two functions that prints a SINGLE character to binary.

void printbinchar(char character)
{
    char output[9];
    itoa(character, output, 2);
    printf("%s\n", output);
}

printbinchar(10) will write into the console

    1010

itoa is a library function that converts a single integer value to a string with the specified base. For example... itoa(1341, output, 10) will write in output string "1341". And of course itoa(9, output, 2) will write in the output string "1001".

The next function will print into the standard output the full binary representation of a character, that is, it will print all 8 bits, also if the higher bits are zero.

void printbincharpad(char c)
{
    for (int i = 7; i >= 0; --i)
    {
        putchar( (c & (1 << i)) ? '1' : '0' );
    }
    putchar('\n');
}

printbincharpad(10) will write into the console

    00001010

Now i present a function that prints out an entire string (without last null character).

void printstringasbinary(char* s)
{
    // A small 9 characters buffer we use to perform the conversion
    char output[9];

    // Until the first character pointed by s is not a null character
    // that indicates end of string...
    while (*s)
    {
        // Convert the first character of the string to binary using itoa.
        // Characters in c are just 8 bit integers, at least, in noawdays computers.
        itoa(*s, output, 2);

        // print out our string and let's write a new line.
        puts(output);

        // we advance our string by one character,
        // If our original string was "ABC" now we are pointing at "BC".
        ++s;
    }
}

Consider however that itoa don't adds padding zeroes, so printstringasbinary("AB1") will print something like:

1000001
1000010
110001

//prompts for input in javascript
test=prompt("Enter a value?","some string");

//passes javascript to a hidden field.
document.getElementById('myField').value = test;

//prompts for input in javascript
test2=prompt("Enter a value?","some string2");

//passes javascript to a hidden field
document.getElementById('myField').value = test2;

//prints output
document.write("hello, "+test+test2;

now this is confusing but this should work...

There are basically two most popular answers. The first one basically says

Optimistic needs a three-tier architectures where you do not necessarily maintain a connection to the database for your session whereas Pessimistic Locking is when you lock the record for your exclusive use until you have finished with it. It has much better integrity than optimistic locking you need either a direct connection to the database.

Another answer is

optimistic (versioning) is faster because of no locking but (pessimistic) locking performs better when contention is high and it is better to prevent the work rather than discard it and start over.

or

Optimistic locking works best when you have rare collisions

As it is put on this page.

I created my answer to explain how "keep connection" is related to "low collisions".

To understand which strategy is best for you, think not about the Transactions Per Second your DB has but the duration of a single transaction. Normally, you open trasnaction, performa operation and close the transaction. This is a short, classical transaction ANSI had in mind and fine to get away with locking. But, how do you implement a ticket reservation system where many clients reserve the same rooms/seats at the same time?

You browse the offers, fill in the form with lots of available options and current prices. It takes a lot of time and options can become obsolete, all the prices invalid between you started to fill the form and press "I agree" button because there was no lock on the data you have accessed and somebody else, more agile, has intefered changing all the prices and you need to restart with new prices.

You could lock all the options as you read them, instead. This is pessimistic scenario. You see why it sucks. Your system can be brought down by a single clown who simply starts a reservation and goes smoking. Nobody can reserve anything before he finishes. Your cash flow drops to zero. That is why, optimistic reservations are used in reality. Those who dawdle too long have to restart their reservation at higher prices.

In this optimistic approach you have to record all the data that you read (as in mine Repeated Read) and come to the commit point with your version of data (I want to buy shares at the price you displayed in this quote, not current price). At this point, ANSI transaction is created, which locks the DB, checks if nothing is changed and commits/aborts your operation. IMO, this is effective emulation of MVCC, which is also associated with Optimistic CC and also assumes that your transaction restarts in case of abort, that is you will make a new reservation. A transaction here involves a human user decisions.

I am far from understanding how to implement the MVCC manually but I think that long-running transactions with option of restart is the key to understanding the subject. Correct me if I am wrong anywhere. My answer was motivated by this Alex Kuznecov chapter.

UPDATE

If you don't need the exact look of a tab (bordered appropriately on the left or right as each tab is activated), you can simple use nav-stacked, along with Bootstrap col-* to float the tabs to the left or right...

nav-stacked demo: http://codeply.com/go/rv3Cvr0lZ4

<ul class="nav nav-pills nav-stacked col-md-3">
    <li><a href="#a" data-toggle="tab">1</a></li>
    <li><a href="#b" data-toggle="tab">2</a></li>
    <li><a href="#c" data-toggle="tab">3</a></li>
</ul>

Remove display: block; in the div #tfl style property

<div id="tfl" style="display: block; width: 187px; height: 260px;

Inline style take priority then css file

When you set keys (primary or foreign) you are setting constraints on how they can be used, which in turn limits what you can do with them. If you really want to alter the column, you could re-create the table without the constraints, although I'd recommend against it. Generally speaking, if you have a situation in which you want to do something, but it is blocked by a constraint, it's best resolved by changing what you want to do rather than the constraint.

Great article i found what worked best for me was to add a % to the size

.wrap {
margin-top:5%;
margin-bottom:5%;
height:100%;
display:block;}

It is very simple, in order to deactivate your virtual env

• If using Anaconda - use conda deactivate
• If not using Anaconda - use source deactivate

At times the error code 409 occurs when you name you folder or files a reserved or blocked name. These could be names like register, contact

In my case I named a folder contact, turns out the name was blocked from being used as folder names.

When testing my script on postman, I was getting this error:

<script>
    document.cookie = "humans_21909=1"; document.location.reload(true)
</script>

I changed the folder name from contact to contacts and it worked. The error was gone.

The best solution, imho, is the one posted here: https://stackoverflow.com/a/3373298/9724628.

It does require python to work, but it seems to cover all or most of the edge cases and be very portable solution.

1. With resolving symlinks:

python -c "import os,sys; print(os.path.realpath(sys.argv[1]))" path/to/file

2. or without it:

python -c "import os,sys; print(os.path.abspath(sys.argv[1]))" path/to/file

Simplified example (with counter):

With Me.lstbox
    .ColumnCount = 2
    .ColumnWidths = "60;60"
    .AddItem
    .List(i, 0) = Company_ID
    .List(i, 1) = Company_name 
    i = i + 1

end with

Make sure to start the counter with 0, not 1 to fill up a listbox.

Necromancing.

In this example, the table name is dbo.T_SYS_Language_Forms, and the column name is LANG_UID

-- First, chech if the table exists...
IF 0 < (
    SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE = 'BASE TABLE'
    AND TABLE_SCHEMA = 'dbo'
    AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
    -- Check for NULL values in the primary-key column
    IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
    BEGIN
        ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL 

        -- No, don't drop, FK references might already exist...
        -- Drop PK if exists 
        -- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name 
        --DECLARE @pkDropCommand nvarchar(1000) 
        --SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
        --WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
        --AND TABLE_SCHEMA = 'dbo' 
        --AND TABLE_NAME = 'T_SYS_Language_Forms' 
        ----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
        --))
        ---- PRINT @pkDropCommand 
        --EXECUTE(@pkDropCommand) 

        -- Instead do
        -- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';


        -- Check if they keys are unique (it is very possible they might not be) 
        IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
        BEGIN

            -- If no Primary key for this table
            IF 0 =  
            (
                SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
                WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
                AND TABLE_SCHEMA = 'dbo' 
                AND TABLE_NAME = 'T_SYS_Language_Forms' 
                -- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
            )
                ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
            ;

            -- Adding foreign key
            IF 0 = (SELECT COUNT(*) FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_NAME = 'FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms') 
                ALTER TABLE T_ZO_SYS_Language_Forms WITH NOCHECK ADD CONSTRAINT FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms FOREIGN KEY(ZOLANG_LANG_UID) REFERENCES T_SYS_Language_Forms(LANG_UID); 
        END -- End uniqueness check
        ELSE
            PRINT 'FSCK, this column has duplicate keys, and can thus not be changed to primary key...' 
    END -- End NULL check
    ELSE
        PRINT 'FSCK, need to figure out how to update NULL value(s)...' 
END 

Perl 5.10+ contains the 'smart-match' operator ~~, which returns true if a certain element is contained in an array or hash, and false if it doesn't (see perlfaq4):

The nice thing is that it also supports regexes, meaning that your case-insensitive requirement can easily be taken care of:

use strict;
use warnings;
use 5.010;

my @array  = qw/aaa bbb/;
my $wanted = 'aAa';

say "'$wanted' matches!" if /$wanted/i ~~ @array;   # Prints "'aAa' matches!"

background-size: 200px 50px change it to 100% 100% and it will scale on the needs of the content tag like ul li or div... tried it

You can make a class for each label and inside it put:

display: inline-block;

And width the value that you need.

Use Sum()

 List<string> foo = new List<string>();
 foo.Add("1");
 foo.Add("2");
 foo.Add("3");
 foo.Add("4");

 Console.Write(foo.Sum(x => Convert.ToInt32(x)));

Prints:

10

Python strings are immutable, you change them by making a copy.
The easiest way to do what you want is probably:

text = "Z" + text[1:]

The text[1:] returns the string in text from position 1 to the end, positions count from 0 so '1' is the second character.

edit: You can use the same string slicing technique for any part of the string

text = text[:1] + "Z" + text[2:]

Or if the letter only appears once you can use the search and replace technique suggested below

Using CSS you can just set display:none for the element in a CSS file or in a style attribute

#div { display:none; }
<div id="div"></div>



<div style="display:none"></div>

or having the js just after the div might be fast enough too, but not as clean

If I'm not wrong, you can start your application using command line and thus also using a batch file. In that case it is not a very hard task to start it with Windows login.

You just create a batch file with the following content:

node C:\myapp.js

and save it with .bat extention. Here myapp.js is your app, which in this example is located in C: drive (spcify the path).

Now you can just throw the batch file in your startup folder which is located at C:\Users\%username%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

Just open it using %appdata% in run dailog box and locate to >Roaming>Microsoft>Windows>Start Menu>Programs>Startup

The batch file will be executed at login time and start your node application from cmd.

import os, sys, re, glob

pattern = re.compile(r"\<\[\d\>")
replacementStringMatchesPattern = "<[1>"

for infile in glob.glob(os.path.join(os.getcwd(), '*.txt')):
   for line in reader: 
      retline =  pattern.sub(replacementStringMatchesPattern, "", line)         
      sys.stdout.write(retline)
      print (retline)

you will need to use window.open(url);

http://uk3.php.net/manual/en/language.basic-syntax.phpmode.php has plenty of advice, including:

while some people find short tags and ASP style tags convenient, they are less portable, and generally not recommended.

and

note that if you are embedding PHP within XML or XHTML you will need to use the <?php ?> tags to remain compliant with standards.

and

Using short tags should be avoided when developing applications or libraries that are meant for redistribution, or deployment on PHP servers which are not under your control, because short tags may not be supported on the target server. For portable, redistributable code, be sure not to use short tags.

What's FAT?

FAT may sound like a strange name for a file system, but it's actually an acronym for File Allocation Table. Introduced in 1981, FAT is ancient in computer terms. Because of its age, most operating systems, including Microsoft Windows NT®, Windows 98, the Macintosh OS, and some versions of UNIX, offer support for FAT.

The FAT file system limits filenames to the 8.3 naming convention, meaning that a filename can have no more than eight characters before the period and no more than three after. Filenames in a FAT file system must also begin with a letter or number, and they can't contain spaces. Filenames aren't case sensitive.

What About VFAT?

Perhaps you've also heard of a file system called VFAT. VFAT is an extension of the FAT file system and was introduced with Windows 95. VFAT maintains backward compatibility with FAT but relaxes the rules. For example, VFAT filenames can contain up to 255 characters, spaces, and multiple periods. Although VFAT preserves the case of filenames, it's not considered case sensitive.

When you create a long filename (longer than 8.3) with VFAT, the file system actually creates two different filenames. One is the actual long filename. This name is visible to Windows 95, Windows 98, and Windows NT (4.0 and later). The second filename is called an MS-DOS® alias. An MS-DOS alias is an abbreviated form of the long filename. The file system creates the MS-DOS alias by taking the first six characters of the long filename (not counting spaces), followed by the tilde [~] and a numeric trailer. For example, the filename Brien's Document.txt would have an alias of BRIEN'~1.txt.

An interesting side effect results from the way VFAT stores its long filenames. When you create a long filename with VFAT, it uses one directory entry for the MS-DOS alias and another entry for every 13 characters of the long filename. In theory, a single long filename could occupy up to 21 directory entries. The root directory has a limit of 512 files, but if you were to use the maximum length long filenames in the root directory, you could cut this limit to a mere 24 files. Therefore, you should use long filenames very sparingly in the root directory. Other directories aren't affected by this limit.

You may be wondering why we're discussing VFAT. The reason is it's becoming more common than FAT, but aside from the differences I mentioned above, VFAT has the same limitations. When you tell Windows NT to format a partition as FAT, it actually formats the partition as VFAT. The only time you'll have a true FAT partition under Windows NT 4.0 is when you use another operating system, such as MS-DOS, to format the partition.

FAT32

FAT32 is actually an extension of FAT and VFAT, first introduced with Windows 95 OEM Service Release 2 (OSR2). FAT32 greatly enhances the VFAT file system but it does have its drawbacks.

The greatest advantage to FAT32 is that it dramatically increases the amount of free hard disk space. To illustrate this point, consider that a FAT partition (also known as a FAT16 partition) allows only a certain number of clusters per partition. Therefore, as your partition size increases, the cluster size must also increase. For example, a 512-MB FAT partition has a cluster size of 8K, while a 2-GB partition has a cluster size of 32K.

This may not sound like a big deal until you consider that the FAT file system only works in single cluster increments. For example, on a 2-GB partition, a 1-byte file will occupy the entire cluster, thereby consuming 32K, or roughly 32,000 times the amount of space that the file should consume. This rule applies to every file on your hard disk, so you can see how much space can be wasted.

Converting a partition to FAT32 reduces the cluster size (and overcomes the 2-GB partition size limit). For partitions 8 GB and smaller, the cluster size is reduced to a mere 4K. As you can imagine, it's not uncommon to gain back hundreds of megabytes by converting a partition to FAT32, especially if the partition contains a lot of small files.

Note: This section of the quote/ article (1999) is out of date. Updated info quote below.

As I mentioned, FAT32 does have limitations. Unfortunately, it isn't compatible with any operating system other than Windows 98 and the OSR2 version of Windows 95. However, Windows 2000 will be able to read FAT32 partitions.

The other disadvantage is that your disk utilities and antivirus software must be FAT32-aware. Otherwise, they could interpret the new file structure as an error and try to correct it, thus destroying data in the process.

Finally, I should mention that converting to FAT32 is a one-way process. Once you've converted to FAT32, you can't convert the partition back to FAT16. Therefore, before converting to FAT32, you need to consider whether the computer will ever be used in a dual-boot environment. I should also point out that although other operating systems such as Windows NT can't directly read a FAT32 partition, they can read it across the network. Therefore, it's no problem to share information stored on a FAT32 partition with other computers on a network that run older operating systems.

Updated mentioned in comment by Doktor-J (assimilated to update out of date answer in case comment is ever lost):

I'd just like to point out that most modern operating systems (WinXP/Vista/7/8, MacOS X, most if not all Linux variants) can read FAT32, contrary to what the second-to-last paragraph suggests.

The original article was written in 1999, and being posted on a Microsoft website, probably wasn't concerned with non-Microsoft operating systems anyways.

The operating systems "excluded" by that paragraph are probably the original Windows 95, Windows NT 4.0, Windows 3.1, DOS, etc.

Why not use Html.RenderAction()?

Then you could put the following into any controller (even creating a new controller for it):

[ChildActionOnly]
public ActionResult MyActionThatGeneratesAPartial(string parameter1)
{
    var model = repository.GetThingByParameter(parameter1);
    var partialViewModel = new PartialViewModel(model);
    return PartialView(partialViewModel); 
}

Then you could create a new partial view and have your PartialViewModel be what it inherits from.

For Razor, the code block in the view would look like this:

@{ Html.RenderAction("Index", "Home"); }

For the WebFormsViewEngine, it would look like this:

<% Html.RenderAction("Index", "Home"); %>

One thing to think about is: Do you have your WCF completely uncoupled from the WindowsService (WS)? A WS is painful because you don't have a lot of control or visibility to them. I try to mitigate this by having all of my non-WS stuff in their own classes so they can be tested independently of the host WS. Using this approach might help you eliminate anything that is happening with the WS runtime vs. your service in particular.

John is likely correct that it is a .config file problem. WCF will always look for the execution context .config. So if you are hosting your WCF in different execution contexts (that is, test with a console application, and deploy with a WS), you need to make sure you have WCF configuration data moved over to the proper .config file. But the underlying issue to me is that you don't know what the problem is because the WS goo gets in the way. If you haven't refactored to that yet so that you can run your service in any context (that is, unit test or console), then I'd sugget doing so. If you spun your service up in a unit test, it would likely fail the same way that you are seeing with the WS which is much easier to debug rather than attempting to do so with the yucky WS plumbing.

List is just an interface. The question is: is your actual List implementation serializable? Speaking about the standard List implementations (ArrayList, LinkedList) from the Java run-time, most of them actually are already.

1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math

2: Yes: But you already know it:

`^`(x,y)
#[1] 1024

In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math.

Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply and sapply:

> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )
[1] 1 4

TLDR - In addition to the previous responses. There might be a problem with the version of the fastboot command. Try to download the newest one via Android SDK Manager instead of default one available in the OS repository.

There is one more thing you can do to fix this issue. I had the similar problem when trying to flash Nexus Player. All the adb commands we working fine while in normal boot mode. However, after switching to fastboot mode I wasn't able to execute fastboot commands. My device was not visible in the output of the fastboot devices command. I've set the right rules in /etc/udev/rules.d/11-android.rules file. The lsusb command showed that the device has been pluged in.

The soultion was quite simple. I've downloaded the the fastboot via Android Studio's SDK Manager instead of using the default one available in Ubuntu packages.

All you need is sdkmanager. Download the Android SDK Platform Tools and replace the default /usr/bin/fastboot with the new one.

I know this is an old question.

Here's another option - attending to different platform requirements - Source

<link rel='shortcut icon' type='image/vnd.microsoft.icon' href='/favicon.ico'> <!-- IE -->
<link rel='apple-touch-icon' type='image/png' href='/icon.57.png'> <!-- iPhone -->
<link rel='apple-touch-icon' type='image/png' sizes='72x72' href='/icon.72.png'> <!-- iPad -->
<link rel='apple-touch-icon' type='image/png' sizes='114x114' href='/icon.114.png'> <!-- iPhone4 -->
<link rel='icon' type='image/png' href='/icon.114.png'> <!-- Opera Speed Dial, at least 144×114 px -->

This is the broadest approach I have found so far.

Ultimately the decision depends on your own needs. Ask yourself, who is your target audience?

UPDATE May 27, 2018: As expected, time goes by and things change. But there's good news too. I found a tool called Real Favicon Generator that generates all the required lines for the icon to work on all modern browsers and platforms. It doesn't handle backwards compatibility though.

It means that somewhere a function which should return a image just returned None and therefore has no shape attribute. Try "print img" to check if your image is None or an actual numpy object.

Try this:

Sub GetColumns()

Dim lnRow As Long, lnCol As Long

lnRow = 3 'For testing

lnCol = Sheet1.Cells(lnRow, 1).EntireRow.Find(What:="sds", LookIn:=xlValues, LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlNext, MatchCase:=False).Column

End Sub

Probably best not to use colIndex and rowIndex as variable names as they are already mentioned in the Excel Object Library.

Here is a python3 method using str.translate and str.maketrans:

s = "abc&def#ghi"
print(s.translate(str.maketrans({'&': '\&', '#': '\#'})))

The printed string is abc\&def\#ghi.

SELECT 
   UserID, FirstName, MiddleInitial, LastName
FROM Users
ORDER BY LastName

You can use the function ginv() (Moore-Penrose generalized inverse) in the MASS package

Normal arithmetic is base-10, so decimals represent tenths, hundredths, etc. When you try to represent a floating-point number in binary base-2 arithmetic, you are dealing with halves, fourths, eighths, etc.

In the hardware, floating points are stored as integer mantissas and exponents. Mantissa represents the significant digits. Exponent is like scientific notation but it uses a base of 2 instead of 10. For example 64.0 would be represented with a mantissa of 1 and exponent of 6. 0.125 would be represented with a mantissa of 1 and an exponent of -3.

Floating point decimals have to add up negative powers of 2

0.1b = 0.5d
0.01b = 0.25d
0.001b = 0.125d
0.0001b = 0.0625d
0.00001b = 0.03125d

and so on.

It is common to use a error delta instead of using equality operators when dealing with floating point arithmetic. Instead of

if(a==b) ...

you would use

delta = 0.0001; // or some arbitrarily small amount
if(a - b > -delta && a - b < delta) ...

That is an HTTP header. You would configure your webserver or webapp to send this header ideally. Perhaps in htaccess or PHP.

Alternatively you might be able to use

<head>...<meta http-equiv="Access-Control-Allow-Origin" content="*">...</head>

I do not know if that would work. Not all HTTP headers can be configured directly in the HTML.

This works as an alternative to many HTTP headers, but see @EricLaw's comment below. This particular header is different.

Caveat

This answer is strictly about how to set headers. I do not know anything about allowing cross domain requests.

About HTTP Headers

Every request and response has headers. The browser sends this to the webserver

GET /index.htm HTTP/1.1

Then the headers

Host: www.example.com
User-Agent: (Browser/OS name and version information)
.. Additional headers indicating supported compression types and content types and other info

Then the server sends a response

Content-type: text/html
Content-length: (number of bytes in file (optional))
Date: (server clock)
Server: (Webserver name and version information)

Additional headers can be configured for example Cache-Control, it all depends on your language (PHP, CGI, Java, htaccess) and webserver (Apache, etc).

You can use clip-path, as Stewartside and Sviatoslav Oleksiv mentioned. To make things easy, I created a sass mixin:

@mixin cut-corners ($left-top, $right-top: 0px, $right-bottom: 0px, $left-bottom: 0px) {
  clip-path: polygon($left-top 0%, calc(100% - #{$right-top}) 0%, 100% $right-top, 100% calc(100% - #{$right-bottom}), calc(100% - #{$right-bottom}) 100%, $left-bottom 100%, 0% calc(100% - #{$left-bottom}), 0% $left-top);
}

.cut-corners {
  @include cut-corners(10px, 0, 25px, 50px);
}

days, years, etc., are part of Active Support, So this won't work in irb, but it should work in rails console.

Just to make someone's life easier, the linq query with lambda expression

(from x in Items where x.Id == 123 select x).FirstOrDefault();

does result in an SQL query with a select top (1) in it.

To get the currently logged in user:

System.getProperty("user.name"); //platform independent 

and the hostname of the machine:

java.net.InetAddress localMachine = java.net.InetAddress.getLocalHost();
System.out.println("Hostname of local machine: " + localMachine.getHostName());

I needed to replace the \r\n with an actual carriage return and line feed and replace \t with an actual tab. So I came up with the following:

public string Transform(string data)
{
    string result = data;
    char cr = (char)13;
    char lf = (char)10;
    char tab = (char)9;

    result = result.Replace("\\r", cr.ToString());
    result = result.Replace("\\n", lf.ToString());
    result = result.Replace("\\t", tab.ToString());

    return result;
}

Git now has this functionality built in

git check-ignore *

Of course you can change the glob to something like **/*.dll in your case

Git Reference

You can also use Url.Action for the path instead like so:

$.ajax({
        url: "@Url.Action("Holiday", "Calendar", new { area = "", year= (val * 1) + 1 })",                
        type: "GET",           
        success: function (partialViewResult) {            
            $("#refTable").html(partialViewResult);
        }
    });

I had the same problem and got it resolved by deleting .m2 maven repo (C:\Users\user\ .m2)

If you want to use jQuery you can use .replaceAll()

I had to set

C:\ProgramData\MySQL\MySQL Server 8.0/my.ini  secure-file-priv=""

When I commented line with secure-file-priv, secure-file-priv was null and I couldn't download data.

Do you have a smart phone? Is there one big app or lots of little ones? Does one app reply upon another? Can you use one app while installing, updating, and/or uninstalling another? That each app is self-contained is high cohesion. That each app is independent of the others is low coupling. DevOps favours this architecture because it means you can do discrete continuous deployment without disrupting the system entire.

As commented by Thomas W. - I almost missed this comment but I had the same issues so it's worth rewriting as an answer I think.

The main issue being that after the first assignment of webBrowser1.DocumentText to some html, subsequent assignments had no effect.

The solution as linked by Thomas can be found in detail at http://weblogs.asp.net/gunnarpeipman/archive/2009/08/15/displaying-custom-html-in-webbrowser-control.aspx however I will summarize below in case this page becomes unavailable in the future.

In short, due to the way the webBrowser control works, you must navigate to a new page each time you wish to change the content. Therefore the author proposes a method to update the control as:

private void DisplayHtml(string html)
{
    webBrowser1.Navigate("about:blank");
    if (webBrowser1.Document != null)
    {
        webBrowser1.Document.Write(string.Empty);
    }
    webBrowser1.DocumentText = html;
}

I have however found that in my current application I get a CastException from the line if(webBrowser1.Document != null). I'm not sure why this is, but I've found that if I wrap the whole if block in a try catch the desired effect still works. See:

private void DisplayHtml(string html)
{
    webBrowser1.Navigate("about:blank");
    try
    {
        if (webBrowser1.Document != null)
        {
            webBrowser1.Document.Write(string.Empty);
        }
    }
    catch (CastException e)
    { } // do nothing with this
    webBrowser1.DocumentText = html;
}

So every time the function to DisplayHtml is executed I receive a CastException from the if statement, so the contents of the if statement are never reached. However if I comment out the if statement so as not to receive the CastException, then the browser control doesn't get updated. I suspect there is another side effect of the code behind the Document property which causes this effect despite the fact that it also throws an exception.

Anyway I hope this helps people.

Document.ready (a jQuery event) will fire when all the elements are in place, and they can be referenced in the JavaScript code, but the content is not necessarily loaded. Document.ready executes when the HTML document is loaded.

$(document).ready(function() {

    // Code to be executed
    alert("Document is ready");
});

The window.load however will wait for the page to be fully loaded. This includes inner frames, images, etc.

$(window).load(function() {

    //Fires when the page is loaded completely
    alert("window is loaded");
});

Using Chrome 15.0.865.0 dev. There's an "Event Listeners" section on the Elements panel:

And an "Event Listeners Breakpoints" on the Scripts panel. Use a Mouse -> click breakpoint and then "step into next function call" while keeping an eye on the call stack to see what userland function handles the event. Ideally, you'd replace the minified version of jQuery with an unminified one so that you don't have to step in all the time, and use step over when possible.

In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.

In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.

The /me/friendlists endpoint and user_friendlists permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.

If you want to access a list of non-app-using friends, there are two options:

1. If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.

2. If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.

In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission).

For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

import java.io.File
import kotlin.math.log2
import kotlin.math.pow

/**
 * @author aminography
 */

val File.formatSize: String
    get() = length().formatAsFileSize

val Int.formatAsFileSize: String
    get() = toLong().formatAsFileSize

val Long.formatAsFileSize: String
    get() = log2(if (this != 0L) toDouble() else 1.0).toInt().div(10).let {
        val precision = when (it) {
            0 -> 0; 1 -> 1; else -> 2
        }
        val prefix = arrayOf("", "K", "M", "G", "T", "P", "E", "Z", "Y")
        String.format("%.${precision}f ${prefix[it]}B", toDouble() / 2.0.pow(it * 10.0))
    }

Usage:

println("0:          " + 0.formatAsFileSize)
println("170:        " + 170.formatAsFileSize)
println("14356:      " + 14356.formatAsFileSize)
println("968542985:  " + 968542985.formatAsFileSize)
println("8729842496: " + 8729842496.formatAsFileSize)

println("file: " + file.formatSize)

Result:

0:          0 B
170:        170 B
14356:      14.0 KB
968542985:  923.67 MB
8729842496: 8.13 GB

file: 6.15 MB

Here's a variant of the solution from @JoshuaUlrich that uses the correct size instead of a hard-coded size:

fileName <- 'foo.txt'
readChar(fileName, file.info(fileName)$size)

Note that readChar allocates space for the number of bytes you specify, so readChar(fileName, .Machine$integer.max) does not work well...

I thought I was bright ;-)

In CSS:

option:disabled {display:none;}

In Firefox and Chrome, a select with only the enabled options were created. Nice.

In IE, the enabled options were shown, the disabled where just blank lines, in their original location. Bad.

In Edge, the enabled options shown at top, followed by blank lines for disabled options. Acceptable.

An updated version of Rails/ActiveRecord may support this syntax natively. It would look similar to:

Foo.where(foo: 'bar').or.where(bar: 'bar')

As noted in this pull request https://github.com/rails/rails/pull/9052

For now, simply sticking with the following works great:

Foo.where('foo= ? OR bar= ?', 'bar', 'bar')

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

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

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

Here's a one-liner to swap the values of two variables.
Given variables a and b:

b = [a, a = b][0];

Demonstration below:

var a=1,_x000D_
    b=2,_x000D_
    output=document.getElementById('output');_x000D_
_x000D_
output.innerHTML="<p>Original: "+a+", "+b+"</p>";_x000D_
_x000D_
b = [a, a = b][0];_x000D_
_x000D_
output.innerHTML+="<p>Swapped: "+a+", "+b+"</p>";

<div id="output"></div>

sp_MSforeachdb 'select db_name(), * From ?..sysobjects where xtype in (''U'', ''P'') And name = ''ObjectName'''

Instead of 'ObjectName' insert object you are looking for. First column will display name of database where object is located at.

HTML:

<div class="container">
    <div class="box">
        <img src="http://lorempixel.com/1600/1200/" alt="">
    </div>
</div>

CSS:

.container {
  display: flex;
  flex-direction: row;
  justify-content: center;
  align-items: stretch;

  width: 100%;
  height: 100%;

  border-radius: 4px;
  background-color: hsl(0, 0%, 96%);
}

.box {
  border-radius: 4px;
  display: flex;
}

.box img {
  width: 100%;
  object-fit: contain;
  border-radius: 4px;
}

If you have the disk space, you could use SELECT INTO and create a new table. It's minimally logged, so it would go much faster

select t.*, int_field = CAST(-1 as int)
into mytable_new 
from mytable t

-- create your indexes and constraints

GO

exec sp_rename mytable, mytable_old
exec sp_rename mytable_new, mytable

drop table mytable_old

If you want to interpolate in console.log output, then just

console.log("Eruption 1: %s", eruption1);
                         ^^

Here, %s is what is called a "format specifier". console.log has this sort of interpolation support built-in.

session.query().with_entities(SomeModel.col1)

is the same as

session.query(SomeModel.col1)

for alias, we can use .label()

session.query(SomeModel.col1.label('some alias name'))

The angular2-moment library has pipes like {{myDate | amTimeAgo}} to use in .html files.

Those same pipes can also be accessed as Typescript functions within a component class (.ts) file. First install the library as instructed:

npm install --save angular2-moment

In the node_modules/angular2-moment will now be ".pipe.d.ts" files like calendar.pipe.d.ts, date-format.pipe.d.ts and many more.

Each of those contains the Typescript function name for the equivalent pipe, for example, DateFormatPipe() is the function for amDateFormatPipe.

To use DateFormatPipe in your project, import and add it to your global providers in app.module.ts:

import { DateFormatPipe } from "angular2-moment";
.....
providers: [{provide: ErrorHandler, useClass: IonicErrorHandler}, ...., DateFormatPipe]

Then in any component where you want to use the function, import it on top, inject into the constructor and use:

import { DateFormatPipe } from "angular2-moment";
....
constructor(.......,  public dfp: DateFormatPipe) {
    let raw = new Date(2015, 1, 12);
    this.formattedDate = dfp.transform(raw, 'D MMM YYYY');
}

To use any of the functions follow this process. It would be nice if there was one way to gain access to all the functions, but none of the above solutions worked for me.

It sounds like some of your styles are being reset.

By default in most browsers, uls and ols have margin and padding added to them.

You can override this (and many do) by adding a line to your css like so

ul, ol {  //THERE MAY BE OTHER ELEMENTS IN THE LIST
    margin:0;
    padding:0;
}

In this case, you would remove the element from this list or add a margin/padding back, like so

ul{
    margin:1em;
}

Example: http://jsfiddle.net/jasongennaro/vbMbQ/1/

Make sure to select "All" to find the enable bitcode build settings:

This scope https://www.googleapis.com/auth/userinfo.profile has been deprecated now. Please look at https://developers.google.com/+/api/auth-migration#timetable.

New scope you will be using to get profile info is: profile or https://www.googleapis.com/auth/plus.login

and the endpoint is - https://www.googleapis.com/plus/v1/people/{userId} - userId can be just 'me' for currently logged in user.

This should disconnect everyone else, and leave you as the only user:

alter database YourDb set single_user with rollback immediate

Note: Don't forget

alter database YourDb set MULTI_USER

after you're done!

Why not rewrite it to be

for element in somelist: 
   do_action(element)  

if check(element): 
    remove_element_from_list

See this question for how to remove from the list, though it looks like you've already seen that Remove items from a list while iterating

Another option is to do this if you really want to keep this the same

newlist = [] 
for element in somelist: 
   do_action(element)  

   if not check(element): 
      newlst.append(element)

In case you have a multi-module project :

let us say your module structure is

root-module
 -> a-module
 -> b-module

and the test(testToRun) you are looking to run is in b-module, with full path : com.xyz.b.module.TestClass.testToRun

As here you are interested to run the test in b-module, so you should see the tasks available for b-module.

./gradlew :b-module:tasks

The above command will list all tasks in b-module with description. And in ideal case, you will have a task named test to run the unit tests in that module.

./gradlew :b-module:test

Now, you have reached the point for running all the tests in b-module, finally you can pass a parameter to the above task to run tests which matches the certain path pattern

./gradlew :b-module:test --tests "com.xyz.b.module.TestClass.testToRun"

Now, instead of this if you run

./gradlew test --tests "com.xyz.b.module.TestClass.testToRun"

It will run the test task for both module a and b, which might result in failure as there is nothing matching the above pattern in a-module.

Click is an event that fires immediately after you release the mouse button. So if you want to check in the handler for button2.Click if button1 was clicked before, all you could do is have a handler for button1.Click which sets a bool flag of your own making to true.

private bool button1WasClicked = false;

private void button1_Click(object sender, EventArgs e)
{
    button1WasClicked = true;
}

private void button2_Click(object sender, EventArgs e)
{
    if (textBox2.Text == textBox3.Text && button1WasClicked)
    { 
        StreamWriter myWriter = File.CreateText(@"c:\Program Files\text.txt");
        myWriter.WriteLine(textBox1.Text);
        myWriter.WriteLine(textBox2.Text);
        button1WasClicked = false;
    }
}

There could be many reasons for this. A few that come up quickly to my mind:

1. Did you call this routine AFTER InitializeComponent()?
2. Is the path syntax you are using correct? Does it work if you try it in the debugger? Try using backslash (\) instead of Slash (/) and see.
3. This may be due to side-effects of some other code in your form. Try using the same code in a blank Form (with just the constructor and this function) and check.

This should help. Its CSS3 :first-child where you should say that the first tr of the table you would like to style. http://reference.sitepoint.com/css/pseudoclass-firstchild

This error comes when you only have JRE installed instead of JDK in your JAVA_HOME variable. Unfortunately, you cannot have both of them installed in the same variable so you just need to overwrite the variable with new JDK installation path.

The process should be the same as the way you had JRE installed

The correct way to use max in the having clause is by performing a self join first:

select t1.a, t1.b, t1.c
from table1 t1
join table1 t1_max
  on t1.id = t1_max.id
group by t1.a, t1.b, t1.c
having t1.date = max(t1_max.date)

The following is how you would join with a subquery:

select t1.a, t1.b, t1.c
from table1 t1
where t1.date = (select max(t1_max.date)
                 from table1 t1_max
                 where t1.id = t1_max.id)

Be sure to create a single dataset before using an aggregate when dealing with a multi-table join:

select t1.id, t1.date, t1.a, t1.b, t1.c
into #dataset
from table1 t1
join table2 t2
  on t1.id = t2.id
join table2 t3
  on t1.id = t3.id


select a, b, c
from #dataset d
join #dataset d_max
  on d.id = d_max.id
having d.date = max(d_max.date)
group by a, b, c

Sub query version:

select t1.id, t1.date, t1.a, t1.b, t1.c
into #dataset
from table1 t1
join table2 t2
  on t1.id = t2.id
join table2 t3
  on t1.id = t3.id


select a, b, c
from #dataset d
where d.date = (select max(d_max.date)
                from #dataset d_max
                where d.id = d_max.id)

Here's my one liner for positive integers, based on this answer:

usage:

(-7).Mod(3); // returns 2

implementation:

static int Mod(this int a, int n) => (((a %= n) < 0) ? n : 0) + a;

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

import javax.swing.*;
import javax.swing.table.*;

public class TableCheckBox extends JFrame {

    private static final long serialVersionUID = 1L;
    private JTable table;

    public TableCheckBox() {
        Object[] columnNames = {"Type", "Company", "Shares", "Price", "Boolean"};
        Object[][] data = {
            {"Buy", "IBM", new Integer(1000), new Double(80.50), false},
            {"Sell", "MicroSoft", new Integer(2000), new Double(6.25), true},
            {"Sell", "Apple", new Integer(3000), new Double(7.35), true},
            {"Buy", "Nortel", new Integer(4000), new Double(20.00), false}
        };
        DefaultTableModel model = new DefaultTableModel(data, columnNames);
        table = new JTable(model) {

            private static final long serialVersionUID = 1L;

            /*@Override
            public Class getColumnClass(int column) {
            return getValueAt(0, column).getClass();

            @Override

                switch (column) {

                        return String.class;
                    case 1:

                    case 3:
                        return Double.class;
                    default:
                        return Boolean.class;
                }
            }
        };
        table.setPreferredScrollableViewportSize(table.getPreferredSize());
        JScrollPane scrollPane = new JScrollPane(table);
        getContentPane().add(scrollPane);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                TableCheckBox frame = new TableCheckBox();
                frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
                frame.pack();
                frame.setLocation(150, 150);
                frame.setVisible(true);
            }
        });
    }
}

Using mysqli i've created following function. Asuming you have an mysqli instance called $con.

function table_exist($table){
    global $con;
    $table = $con->real_escape_string($table);
    $sql = "show tables like '".$table."'";
    $res = $con->query($sql);
    return ($res->num_rows > 0);
}

Hope it helps.

Warning: as sugested by @jcaron this function could be vulnerable to sqlinjection attacs, so make sure your $table var is clean or even better use parameterised queries.

Maybe you can simply

$ sudo bash -c "echo vm.overcommit_memory=1 >> /etc/sysctl.conf"
$ sudo sysctl -p

It works for my case.

Adding this answer here since it provides ability to set non-blocking pipes on Windows and Unix.

All the ctypes details are thanks to @techtonik's answer.

There is a slightly modified version to be used both on Unix and Windows systems.

• Python3 compatible (only minor change needed).
• Includes posix version, and defines exception to use for either.

This way you can use the same function and exception for Unix and Windows code.

I had problems with collations as I had most of the tables with Modern_Spanish_CI_AS, but a few, which I had inherited or copied from another Database, had SQL_Latin1_General_CP1_CI_AS collation.

In my case, the easiest way to solve the problem has been as follows:

1. I've created a copy of the tables which were 'Latin American, using script table as...
2. The new tables have obviously acquired the 'Modern Spanish' collation of my database
3. I've copied the data of my 'Latin American' table into the new one, deleted the old one and renamed the new one.

I hope this helps other users.

As mentioned by @no?????z??? and @phoenix - You can indeed use it in stub files. e.g.

class Foo:
    bar: Any = ...
    def __init__(self, name: str=...) -> None: ...

More information and examples of how to use this ellipsis can be discovered here https://www.python.org/dev/peps/pep-0484/#stub-files

But this is obviously performing a 'string' comparison

No. The string will be automatically cast into a DATETIME value.

See 11.2. Type Conversion in Expression Evaluation.

When an operator is used with operands of different types, type conversion occurs to make the operands compatible. Some conversions occur implicitly. For example, MySQL automatically converts numbers to strings as necessary, and vice versa.

I had this error in code that looked like this:

int A = 1;
int B = A;

The fix is to change it to this

int A = 1;
#define B A

The compiler assigns a location in memory to a variable. The second is trying a assign a second variable to the same location as the first - which makes no sense. Using the macro preprocessor solves the problem.

You may consider FluentFTP, previously known as System.Net.FtpClient.

It is released under The MIT License and available on NuGet (FluentFTP).

I've personally always found the csv module kind of annoying. I expect someone else will show you how to do this slickly with it, but my quick and dirty solution is:

with open('dict.csv', 'w') as f:  # This creates the file object for the context 
                                  # below it and closes the file automatically
    l = []
    for k, v in mydict.iteritems(): # Iterate over items returning key, value tuples
        l.append('%s: %s' % (str(k), str(v))) # Build a nice list of strings
    f.write(', '.join(l))                     # Join that list of strings and write out

However, if you want to read it back in, you'll need to do some irritating parsing, especially if it's all on one line. Here's an example using your proposed file format.

with open('dict.csv', 'r') as f: # Again temporary file for reading
    d = {}
    l = f.read().split(',')      # Split using commas
    for i in l:
        values = i.split(': ')   # Split using ': '
        d[values[0]] = values[1] # Any type conversion will need to happen here

That's just the usual ternary operator. If the part before the question mark is true, it evaluates and returns the part before the colon, otherwise it evaluates and returns the part after the colon.

a?b:c

is like

if(a)
    b;
else
    c;

By value, what worked for me with jQuery 1.7 was the below code, try this:

$('#id option[value=theOptionValue]').prop('selected', 'selected').change();

FYI...if you use TortoiseSVN and you want to create a simple batch file to xcopy (or directory mirror) entire repositories into a "safe" location on a periodic basis, then this is the specific code that you might want to use. It copies over the hidden directories/files, maintains read-only attributes, and all subdirectories and best of all, doesn't prompt for input. Just make sure that you assign folder1 (safe repo) and folder2 (usable repo) correctly.

@echo off
echo "Setting variables..."
set folder1="Z:\Path\To\Backup\Repo\Directory"
set folder2="\\Path\To\Usable\Repo\Directory"
echo "Removing sandbox version..."
IF EXIST %folder1% (
    rmdir %folder1% /s /q
)
echo "Copying official repository into backup location..."
xcopy /e /i /v /h /k %folder2% %folder1%

And, that's it folks!

Add to your scheduled tasks and never look back.

First of all we open the file and as datafile then we apply .read() method reads the file contents and then we split the data which returns something like: ['5', '10', '6', '6', '20', '1', '7', '30', '4', '8', '40', '3', '9', '23', '1', '4', '13', '6'] and the we applied list slicing on this list to start from the element at index position 1 and skip next 3 elements untill it hits the end of the loop.

with open("sample.txt", "r") as datafile:
    print datafile.read().split()[1::3]

Output:

['10', '20', '30', '40', '23', '13']

The most compatible command I've found for gcc and clang on Linux (thanks to armando.sano):

$ gcc -m64 -Xlinker --verbose  2>/dev/null | grep SEARCH | sed 's/SEARCH_DIR("=\?\([^"]\+\)"); */\1\n/g'  | grep -vE '^$'

if you give -m32, it will output the correct library directories.

Examples on my machine:

for g++ -m64:

/usr/x86_64-linux-gnu/lib64
/usr/i686-linux-gnu/lib64
/usr/local/lib/x86_64-linux-gnu
/usr/local/lib64
/lib/x86_64-linux-gnu
/lib64
/usr/lib/x86_64-linux-gnu
/usr/lib64
/usr/local/lib
/lib
/usr/lib

for g++ -m32:

/usr/i686-linux-gnu/lib32
/usr/local/lib32
/lib32
/usr/lib32
/usr/local/lib/i386-linux-gnu
/usr/local/lib

You can use google-gson. Details:

Object Examples

class BagOfPrimitives {
  private int value1 = 1;
  private String value2 = "abc";
  private transient int value3 = 3;
  BagOfPrimitives() {
    // no-args constructor
  }
}

(Serialization)

BagOfPrimitives obj = new BagOfPrimitives();
Gson gson = new Gson();
String json = gson.toJson(obj); 
==> json is {"value1":1,"value2":"abc"}

Note that you can not serialize objects with circular references since that will result in infinite recursion.

(Deserialization)

BagOfPrimitives obj2 = gson.fromJson(json, BagOfPrimitives.class);  
==> obj2 is just like obj

Another example for Gson:

Gson is easy to learn and implement, you need to know is the following two methods:

-> toJson() – convert java object to JSON format

-> fromJson() – convert JSON into java object

import com.google.gson.Gson;

public class TestObjectToJson {
  private int data1 = 100;
  private String data2 = "hello";

  public static void main(String[] args) {
      TestObjectToJson obj = new TestObjectToJson();
      Gson gson = new Gson();

      //convert java object to JSON format
      String json = gson.toJson(obj);

      System.out.println(json);
  }

}

Output

{"data1":100,"data2":"hello"}

No one mentioned this but it helped me out and not many places on the net mention it.

Make sure your php.ini sets the following key:

    upload_tmp_dir="/path/to/some/tmp/folder"

You'll need to check with your webhost if they want you to use an absolute server file path. You should be able to see other directory examples in your php.ini file to determine this. As soon as I set it I got values in my _FILES object.

Finally make sure that your tmp folder and wherever you are moving files to have the correct permissions so that they can be read and written to.

There are different ways. If you just want to check if one list contains any element from the other list, you can do this..

not set(list1).isdisjoint(list2)

I believe using isdisjoint is better than intersection for Python 2.6 and above.

First up let me start by saying why we need a database.

We need a database to help organise information in such a manner that we can retrieve that data stored in a efficient manner.

Examples of relational database management systems(SQL):

1)Oracle Database

2)SQLite

3)PostgreSQL

4)MySQL

5)Microsoft SQL Server

6)IBM DB2

Examples of non relational database management systems(NoSQL)

1)MongoDB

2)Cassandra

3)Redis

4)Couchbase

5)HBase

6)DocumentDB

7)Neo4j

Relational databases have normalized data, as in information is stored in tables in forms of rows and columns, and normally when data is in normalized form, it helps to reduce data redundancy, and the data in tables are normally related to each other, so when we want to retrieve the data, we can query the data by using join statements and retrieve data as per our need.This is suited when we want to have more writes, less reads, and not much data involved, also its really easy relatively to update data in tables than in non relational databases. Horizontal scaling not possible, vertical scaling possible to some extent.CAP(Consistency, Availability, Partition Tolerant), and ACID (Atomicity, Consistency, Isolation, Duration)compliance.

Let me show entering data to a relational database using PostgreSQL as an example.

First create a product table as follows:

CREATE TABLE products (
    product_no integer,
    name text,
    price numeric
);

then insert the data

INSERT INTO products (product_no, name, price) VALUES (1, 'Cheese', 9.99);

Let's look at another different example:

Here in a relational database, we can link the student table and subject table using relationships, via foreign key, subject ID, but in a non relational database no need to have two documents, as no relationships, so we store all the subject details and student details in one document say student document, then data is getting duplicated, which makes updating records troublesome.

In non relational databases, there is no fixed schema, data is not normalized. no relationships between data is created, all data mostly put in one document. Well suited when handling lots of data, and can transfer lots of data at once, best where high amounts of reads and less writes, and less updates, bit difficult to query data, as no fixed schema. Horizontal and vertical scaling is possible.CAP (Consistency, Availability, Partition Tolerant)and BASE (Basically Available, soft state, Eventually consistent)compliance.

Let me show an example to enter data to a non relational database using Mongodb

db.users.insertOne({name: ‘Mary’, age: 28 , occupation: ‘writer’ })
db.users.insertOne({name: ‘Ben’ , age: 21})

Hence you can understand that to the database called db, and there is a collections called users, and document called insertOne to which we add data, and there is no fixed schema as our first record has 3 attributes, and second attribute has 2 attributes only, this is no problem in non relational databases, but this cannot be done in relational databases, as relational databases have a fixed schema.

Let's look at another different example

({Studname: ‘Ash’, Subname: ‘Mathematics’, LecturerName: ‘Mr. Oak’})

Hence we can see in non relational database we can enter both student details and subject details into one document, as no relationships defined in non relational databases, but here this way can lead to data duplication, and hence errors in updating can occur therefore.

Hope this explains everything

You should be checking the root directory and not the app directory.

Look in $ROOT/storage/laravel.log not app/storage/laravel.log, where root is the top directory of the project.

If you are having very narrow and specific use-case like replacing a particular parameter of given name that have alpha-numeric values with certain special characters capped upto certain length limit, you could try this approach:

urlValue.replace(/\bsrc=[0-9a-zA-Z_@.#+-]{1,50}\b/, 'src=' + newValue);

Example:

let urlValue = 'www.example.com?a=b&src=test-value&p=q';
const newValue = 'sucess';
console.log(urlValue.replace(/\bsrc=[0-9a-zA-Z_@.#+-]{1,50}\b/, 'src=' + newValue));
// output - www.example.com?a=b&src=sucess&p=q

try creating connection string this way:

MySqlConnectionStringBuilder conn_string = new MySqlConnectionStringBuilder();
conn_string.Server = "mysql7.000webhost.com";
conn_string.UserID = "a455555_test";
conn_string.Password = "a455555_me";
conn_string.Database = "xxxxxxxx";

using (MySqlConnection conn = new MySqlConnection(conn_string.ToString()))
using (MySqlCommand cmd = conn.CreateCommand())
{    //watch out for this SQL injection vulnerability below
     cmd.CommandText = string.Format("INSERT Test (lat, long) VALUES ({0},{1})",
                                    OSGconv.deciLat, OSGconv.deciLon);
     conn.Open();
     cmd.ExecuteNonQuery();
}

Check this out,

body {
    background-color: black;
    background: url(img/bg.jpg) no-repeat center center fixed; 
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
}

import difflib
f=open('a.txt','r')  #open a file
f1=open('b.txt','r') #open another file to compare
str1=f.read()
str2=f1.read()
str1=str1.split()  #split the words in file by default through the spce
str2=str2.split()
d=difflib.Differ()     # compare and just print
diff=list(d.compare(str2,str1))
print '\n'.join(diff)

You can check your g++ by command:

which g++
g++ --version

this will tell you which complier is currently it is pointing.

To switch to g++ 4.7 (assuming that you have installed it in your machine),run:

sudo update-alternatives --config gcc

There are 2 choices for the alternative gcc (providing /usr/bin/gcc).

  Selection    Path              Priority   Status
------------------------------------------------------------
  0            /usr/bin/gcc-4.6   60        auto mode
  1            /usr/bin/gcc-4.6   60        manual mode
* 2            /usr/bin/gcc-4.7   40        manual mode

Then select 2 as selection(My machine already pointing to g++ 4.7,so the *)

Once you switch the complier then again run g++ --version to check the switching has happened correctly.

Now compile your program with

g++ -std=c++11 your_file.cpp -o main

The ability to search commits has recently been added to GitHub.

To search for a hash, just enter at least the first 7 characters in the search box. Then on the results page, click the "Commits" tab to see matching commits (but only on the default branch, usually master), or the "Issues" tab to see pull requests containing the commit.

To be more explicit you can add the hash: prefix to the search, but it's not really necessary.

There is also a REST API (at the time of writing it is still in preview).

As of PHP 5.3, you can use openssl_random_pseudo_bytes():

$hex_string = bin2hex(openssl_random_pseudo_bytes(3));

With the addition of Python 3, here is an updated code that works:

import numpy as n
import scipy as s
import matplotlib.pylab as p #pylab is part of matplotlib

xa=0.252
xb=1.99

C=n.linspace(xa,xb,100)
print(C)
iter=1000
Y = n.ones(len(C))

for x in range(iter):
    Y = Y**2 - C   #get rid of early transients

for x in range(iter): 
    Y = Y**2 - C
    p.plot(C,Y, '.', color = 'k', markersize = 2)

p.show()

Uploading on Instagram is possible. Their API provides a media upload endpoint, even if it's not documented.

POST https://instagram.com/api/v1/media/upload/

Check this code for example https://code.google.com/p/twitubas/source/browse/common/instagram.php

There are two types in this parsing.

1. Parsing data from a file from a system path
2. Parsing JSON from remote URL.

From a file, you can use the following

import json
json = json.loads(open('/path/to/file.json').read())
value = json['key']
print json['value']

This arcticle explains the full parsing and getting values using two scenarios.Parsing JSON using Python

Just as an alternative, you can use ancestor.

//*[title="50"]/ancestor::store

It's more powerful than parent since it can get even the grandparent or great great grandparent

Had the same problem with base64. For anyone in the future with the same problem:

url = "data:image/png;base64,iVBORw0KGgoAAAAAAAAyCAYAAAAUYybjAAAgAElE...";

This would work executed from console, but not from within a script:

$img.css("background-image", "url('" + url + "')");

But after playing with it a bit, I came up with this:

var img = new Image();
img.src = url;
$img.css("background-image", "url('" + img.src + "')");

No idea why it works with a proxy image, but it does. Tested on Firefox Dev 37 and Chrome 40.

Hope it helps someone.

EDIT

Investigated a little bit further. It appears that sometimes base64 encoding (at least in my case) breaks with CSS because of line breaks present in the encoded value (in my case value was generated dynamically by ActionScript).

Simply using e.g.:

$img.css("background-image", "url('" + url.replace(/(\r\n|\n|\r)/gm, "") + "')");

works too, and even seems to be faster by a few ms than using a proxy image.

Don't forget the awesome

git fetch -p

which fetches and prunes all origins.

As of 1.10.5, simply include

'orderable: false'

in columnDefs and target your column with

'targets: [0,1]'

Table should like like:

var table = $('#data-tables').DataTable({
    columnDefs: [{
        targets: [0],
        orderable: false
    }]
});

Auto reload with target of your choice. In this case target is _self set to every 5 minutes.

300000 milliseconds = 300 seconds = 5 minutes

as 60000 milliseconds = 60 seconds = 1 minute.

This is how you do it:

<script type="text/javascript">
function load()
{
setTimeout("window.open('http://YourPage.com', '_self');", 300000);
}
</script>
<body onload="load()">

Or this if it is the same page to reload itself:

<script type="text/javascript">
function load()
{
setTimeout("window.open(self.location, '_self');", 300000);
}
</script>
<body onload="load()">

You can do this from ECMAScript 6 onwards using arrays and "destructuring assignments". Note that these are not available in older Javascript versions (meaning — neither with ECMAScript 3rd nor 5th editions).

It allows you to assign to 1+ variables simultaneously:

var [x, y] = [1, 2];
x; // 1
y; // 2

// or

[x, y] = (function(){ return [3, 4]; })();
x; // 3
y; // 4

You can also use object destructuring combined with property value shorthand to name the return values in an object and pick out the ones you want:

let {baz, foo} = (function(){ return {foo: 3, bar: 500, baz: 40} })();
baz; // 40
foo; // 3

And by the way, don't be fooled by the fact that ECMAScript allows you to return 1, 2, .... What really happens there is not what might seem. An expression in return statement — 1, 2, 3 — is nothing but a comma operator applied to numeric literals (1 , 2, and 3) sequentially, which eventually evaluates to the value of its last expression — 3. That's why return 1, 2, 3 is functionally identical to nothing more but return 3.

return 1, 2, 3;
// becomes
return 2, 3;
// becomes
return 3;

For me the solution was just replace unsigned with index

This is the full code:

    Schema::create('champions_overview',function (Blueprint $table){
        $table->engine = 'InnoDB';
        $table->increments('id');
        $table->integer('cid')->index();
        $table->longText('name');
    });


    Schema::create('champions_stats',function (Blueprint $table){
        $table->engine = 'InnoDB';
        $table->increments('id');
        $table->integer('championd_id')->index();
        $table->foreign('championd_id', 'ch_id')->references('cid')->on('champions_overview');
    });

CtrlK for comment (Visual Mode):

vnoremap <silent> <C-k> :s#^#\##<cr>:noh<cr>

CtrlU for uncomment (Visual Mode):

vnoremap <silent> <C-u> :s#^\###<cr>:noh<cr>

From GC Performance Tuning training documents of Oracle:

-Xmn[size]: Size of young generation heap space.

Applications with emphasis on performance tend to use -Xmn to size the young generation, because it combines the use of -XX:MaxNewSize and -XX:NewSize and almost always explicitly sets -XX:PermSize and -XX:MaxPermSize to the same value.

In short, it sets the NewSize and MaxNewSize values of New generation to the same value.

I keep thinking there must be a better idiom, but for subtraction of columns by name, I tend to do the following:

df <- data.frame(a=1:10, b=1:10, c=1:10, d=1:10)

# return everything except a and c
df <- df[,-match(c("a","c"),names(df))]
df

You should set default values in migrations:

$table->tinyInteger('role')->default(1);

You can use this:

select count(customer) as count, pets
from table
group by pets

Try this:

1. Create a placeholder base class (%base-class) with the common properties
2. Extend your class (.my-base-class) with this placeholder.

3. Now you can extend %base-class in any of your classes (e.g. .my-class).

   %base-class {
      width: 80%;
      margin-left: 10%;
      margin-right: 10%;
   }
   
   .my-base-class {
       @extend %base-class;
   }
   
   .my-class {
       @extend %base-class;
       margin-bottom: 40px;
   }
   

You can use Class.isArray()

public static boolean isArray(Object obj)
{
    return obj!=null && obj.getClass().isArray();
}

This works for both object and primitive type arrays.

For toString take a look at Arrays.toString. You'll have to check the array type and call the appropriate toString method.

You can do something like this

import React from 'react';

class Header extends React.Component {

constructor() {
    super();
}

checkClick(e, notyId) {
    alert(notyId);
}

render() {
    return (
        <PopupOver func ={this.checkClick } />
    )
}
};

class PopupOver extends React.Component {

constructor(props) {
    super(props);
    this.props.func(this, 1234);
}

render() {
    return (
        <div className="displayinline col-md-12 ">
            Hello
        </div>
    );
}
}

export default Header;

Using statics

var MyComponent = React.createClass({
 statics: {
 customMethod: function(foo) {
  return foo === 'bar';
  }
 },
   render: function() {
 }
});

MyComponent.customMethod('bar');  // true

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

You can do it by setting the aspect of the image manually (or by letting it auto-scale to fill up the extent of the figure).

By default, imshow sets the aspect of the plot to 1, as this is often what people want for image data.

In your case, you can do something like:

import matplotlib.pyplot as plt
import numpy as np

grid = np.random.random((10,10))

fig, (ax1, ax2, ax3) = plt.subplots(nrows=3, figsize=(6,10))

ax1.imshow(grid, extent=[0,100,0,1])
ax1.set_title('Default')

ax2.imshow(grid, extent=[0,100,0,1], aspect='auto')
ax2.set_title('Auto-scaled Aspect')

ax3.imshow(grid, extent=[0,100,0,1], aspect=100)
ax3.set_title('Manually Set Aspect')

plt.tight_layout()

If you are calling regasm rarely, or calling it from a batch file, you may find it is simpler to just invoke regasm via the fully-qualified pathname on the exe, eg:

c:\Windows\Microsoft.NET\Framework\v2.0.50727\regasm.exe   MyAssembly.dll

Try following query to format datetime in sql server

FORMAT (frr.valid_from , 'dd/MM/yyyy hh:mm:ss')

I have a new solution hide the column on client side using css or javascript or jquery.

.col0
{
  display: none;
}

And in the aspx file where you add the column you should specify the CSS properties:

<asp:BoundField HeaderText="Address Key" DataField="Address_Id" ItemStyle-CssClass="col0" HeaderStyle-CssClass="col0" > </asp:BoundField>

And, how about this ...

string[] sizes = new string[] { "105", "101", "102", "103", "90" };

var size = from x in sizes
           orderby x.Length, x
           select x;

foreach (var p in size)
{
    Console.WriteLine(p);
}

For starters,

mysql_connect() should not have a $ accompanying it; it is not a variable, it is a predefined function. Remove the $ to properly connect to the database.

Why do you have an XML tag at the top of this document? This is HTML/PHP - a HTML doctype should suffice.

From line 215, update:

if (isset($_POST)) {
    $Name = $_POST['Name'];
    $Surname = $_POST['Surname'];

    $Username = $_POST['Username'];

    $Email = $_POST['Email'];
    $C_Email = $_POST['C_Email'];

    $Password = $_POST['password'];
    $C_Password = $_POST['c_password'];

    $SecQ = $_POST['SecQ'];
    $SecA = $_POST['SecA'];
}

POST variables are coming from your form, and you have to check whether they exist or not, else PHP will give you a NOTICE error. You can disable these notices by placing error_reporting(0); at the top of your document. It's best to keep these visible for development purposes.

You should only be interacting with the database (inserting, checking) under the condition that the form has been submitted. If you do not, PHP will run all of these operations without any input from the user. Its best to use an IF statement, like so:

if (isset($_POST['submit']) {
// blah blah
// check if user exists, check if fields are blank
// insert the user if all of this stuff checks out..
} else {
// just display the form
}

Android Design Support Library can be used to show/hide toolbar.

See this. http://android-developers.blogspot.kr/2015/05/android-design-support-library.html

And there are detail samples here. http://inthecheesefactory.com/blog/android-design-support-library-codelab/en

or you can do like

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        new Thread( SampleFunction ).Start();
    }

    void SampleFunction()
    {
        // Gets executed on a seperate thread and 
        // doesn't block the UI while sleeping
        for ( int i = 0; i < 5; i++ )
        {
            this.Invoke( ( MethodInvoker )delegate()
            {
                textBox1.Text += "hi";
            } );
            Thread.Sleep( 1000 );
        }
    }
}

Well, the "-a" mail and mailx in Centos7 is "attach file" not "append header." My shortest path to a solution on Centos7 from here: stackexchange.com

Basically:

yum install mutt
mutt -e 'set content_type=text/html' -s 'My subject' [email protected] < msg.html

Pattern class is the entry point of the regex engine.You can use it through Pattern.matches() and Pattern.comiple(). #Difference between these two. matches()- for quickly check if a text (String) matches a given regular expression comiple()- create the reference of Pattern. So can use multiple times to match the regular expression against multiple texts.

For reference:

public static void main(String[] args) {
     //single time uses
     String text="The Moon is far away from the Earth";
     String pattern = ".*is.*";
     boolean matches=Pattern.matches(pattern,text);
     System.out.println("Matches::"+matches);

    //multiple time uses
     Pattern p= Pattern.compile("ab");
     Matcher  m=p.matcher("abaaaba");
     while(m.find()) {
         System.out.println(m.start()+ " ");
     }
}

You can simply press Ctrl+F5 instead of F5 to run the built code. Then it will prompt you to press any key to continue. Or you can use this line -> system("pause"); at the end of the code to make it wait until you press any key.

However, if you use the above line, system("pause"); and press Ctrl+F5 to run, it will prompt you twice!

Just Remove the type="text/javascript"

<script src="JavaScript/jquery.js" />
<script src="JavaScript/bootstrap-min.js" />

Here is the update - http://jsfiddle.net/andieje/kRX6n/

One that worked for me was:

.+(\\.+)$

Try it online!

Explanation:

.+     - any character except newline
(      - create a group
 \\.+   - match a backslash, and any characters after it
)      - end group
$      - this all has to happen at the end of the string

On Windows Server 2016 Standard, which is what I develop on, I just had to open the Credential Manager Control Panel and clear out the cached proxy settings for Visual Studio which were no longer valid and then restart Visual Studio. The next time I opened the Nuget Package Manager I was prompted for proxy credentials, which got me working again.

See: https://support.microsoft.com/en-us/help/4026814/windows-accessing-credential-manager

This problem i had in my code. I will paste some example code i have over came below error. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.

 String query = "insert into STATION2(ID,CITY,STATE,LAT_N,LONG_W) values('" + a1 + "','" + b1 + "','" + c1 + "','" + d1 + "','" + f1 + "')";
    //,'" + d1 + "','" + f1 + "','" + g1 + "'

    SqlConnection con = new SqlConnection(mycon);
    con.Open();
    SqlCommand cmd = new SqlCommand();
    cmd.CommandText = query;
    cmd.Connection = con;
    cmd.ExecuteNonQuery();
    **con.Close();**

You want to close the connection each and every time. Before that i didn't us the close connect due to this i got error. After adding close statement i have over came this error

Try use the library : https://imapx.codeplex.com/

That library free, open source and have example at this : https://imapx.codeplex.com/wikipage?title=Sample%20code%20for%20get%20messages%20from%20your%20inbox

Your XML is slightly wrong, you need to add any class exclusions within an excludes parent field, so your above configuration should look like the following as per the Jacoco docs

<configuration>
    <excludes>
        <exclude>**/*Config.*</exclude>
        <exclude>**/*Dev.*</exclude>
    </excludes>
</configuration>

The values of the exclude fields should be class paths (not package names) of the compiled classes relative to the directory target/classes/ using the standard wildcard syntax

*   Match zero or more characters
**  Match zero or more directories
?   Match a single character

You may also exclude a package and all of its children/subpackages this way:

<exclude>some/package/**/*</exclude>

This will exclude every class in some.package, as well as any children. For example, some.package.child wouldn't be included in the reports either.

I have tested and my report goal reports on a reduced number of classes using the above.

If you are then pushing this report into Sonar, you will then need to tell Sonar to exclude these classes in the display which can be done in the Sonar settings

Settings > General Settings > Exclusions > Code Coverage

Sonar Docs explains it a bit more

Running your command above

mvn clean verify

Will show the classes have been excluded

No exclusions

[INFO] --- jacoco-maven-plugin:0.7.4.201502262128:report (post-test) @ ** ---

With exclusions

Hope this helps

The root cause of IllegalStateException exception is a java servlet is attempting to write to the output stream (response) after the response has been committed.

It is always better to ensure that no content is added to the response after the forward or redirect is done to avoid IllegalStateException. It can be done by including a ‘return’ statement immediately next to the forward or redirect statement.

In Python, curly braces are used to define a dictionary.

a={'one':1, 'two':2, 'three':3}
a['one']=1
a['three']=3

In other languages, { } are used as part of the flow control. Python however used indentation as its flow control because of its focus on readable code.

The best option is to use jax-ws-catalog.xml

When you compile the local WSDL file , override the WSDL location and set it to something like

http://localhost/wsdl/SOAService.wsdl

Don't worry this is only a URI and not a URL , meaning you don't have to have the WSDL available at that address.
You can do this by passing the wsdllocation option to the wsdl to java compiler.

Doing so will change your proxy code from

static {
    URL url = null;
    try {
        URL baseUrl;
        baseUrl = com.ibm.eci.soaservice.SOAService.class.getResource(".");
        url = new URL(baseUrl, "file:/C:/local/path/to/wsdl/SOAService.wsdl");
    } catch (MalformedURLException e) {
        logger.warning("Failed to create URL for the wsdl Location: 'file:/C:/local/path/to/wsdl/SOAService.wsdl', retrying as a local file");
        logger.warning(e.getMessage());
    }
    SOASERVICE_WSDL_LOCATION = url;
}

to

static {
    URL url = null;
    try {
        URL baseUrl;
        baseUrl = com.ibm.eci.soaservice.SOAService.class.getResource(".");
        url = new URL(baseUrl, "http://localhost/wsdl/SOAService.wsdl");
    } catch (MalformedURLException e) {
        logger.warning("Failed to create URL for the wsdl Location: 'http://localhost/wsdl/SOAService.wsdl', retrying as a local file");
        logger.warning(e.getMessage());
    }
    SOASERVICE_WSDL_LOCATION = url;
}

Notice file:// changed to http:// in the URL constructor.

Now comes in jax-ws-catalog.xml. Without jax-ws-catalog.xml jax-ws will indeed try to load the WSDL from the location

http://localhost/wsdl/SOAService.wsdl

But with jax-ws-catalog.xml you can redirect jax-ws to a locally packaged WSDL whenever it tries to access the WSDL @

http://localhost/wsdl/SOAService.wsdl

Here's jax-ws-catalog.xml

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="system">
        <system systemId="http://localhost/wsdl/SOAService.wsdl"
                uri="wsdl/SOAService.wsdl"/>
    </catalog>

What you are doing is telling jax-ws that when ever it needs to load WSDL from

http://localhost/wsdl/SOAService.wsdl

Now where should you put wsdl/SOAService.wsdl and jax-ws-catalog.xml ? That's the million dollar question isn't it ?
It should be in the META-INF directory of your application jar.

so something like this

ABCD.jar  
|__ META-INF    
    |__ jax-ws-catalog.xml  
    |__ wsdl  
        |__ SOAService.wsdl  

This way you don't even have to override the URL in your client that access the proxy. The WSDL is picked up from within your JAR, and you avoid having to have hard-coded filesystem paths in your code.

More info on jax-ws-catalog.xml http://jax-ws.java.net/nonav/2.1.2m1/docs/catalog-support.html

Hope that helps

addition to the previous answer add file path directory for the write operation

 fs.writeFile(path.join(__dirname,jsonPath), JSON.stringify(newFileData), function (err) {}

>>> keys = ('name', 'age', 'food')
>>> values = ('Monty', 42, 'spam')
>>> dict(zip(keys, values))
{'food': 'spam', 'age': 42, 'name': 'Monty'}

Please be noted, we need to add google maven to use support library starting from revision 25.4.0. As in the release note says:

Important: The support libraries are now available through Google's Maven repository. You do not need to download the support repository from the SDK Manager. For more information, see Support Library Setup.

Read more at Support Library Setup.

Play services and Firebase dependencies since version 11.2.0 are also need google maven. Read Some Updates to Apps Using Google Play services and Google APIs Android August 2017 - version 11.2.0 Release note.

So you need to add the google maven to your root build.gradle like this:

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

For Gradle build tools plugin version 3.0.0, you can use google() repository (more at Migrate to Android Plugin for Gradle 3.0.0):

allprojects {
    repositories {
        jcenter()
        google()
    }
}

UPDATE:

From Google's Maven repository:

The most recent versions of the following Android libraries are available from Google's Maven repository:

• Android Support Library
• Architecture Components Library
• Constraint Layout Library
• Android Test Support Library
• Databinding Library
• Android Instant App Library
• Google Play services
• Firebase

To add them to your build, you need to first include Google's Maven repository in your top-level / root build.gradle file:

allprojects {
    repositories {
        google()

        // If you're using a version of Gradle lower than 4.1, you must instead use:
        // maven {
        //     url 'https://maven.google.com'
        // }
        // An alternative URL is 'https://dl.google.com/dl/android/maven2/'
    }
}

Then add the desired library to your module's dependencies block. For example, the appcompat library looks like this:

dependencies {
    compile 'com.android.support:appcompat-v7:26.1.0'
}

However, if you're trying to use an older version of the above libraries and your dependency fails, then it's not available in the Maven repository and you must instead get the library from the offline repository.

Although my emphatic advice to you is to structure your sql so as to not attempt duplicate inserts (Philip Kelley's snippet is probably what you need), I want to mention that an error on a statement doesn't necessarily cause a rollback.

Unless XACT_ABORT is ON, a transaction will not automatically rollback if an error is encountered unless it's severe enough to kill the connection. XACT_ABORT defaults to OFF.

For example, the following sql successfully inserts three values into the table:

create table x ( y int not null primary key )

begin transaction
insert into x(y)
values(1)
insert into x(y)
values(2)
insert into x(y)
values(2)
insert into x(y)
values(3)
commit

Unless you're setting XACT_ABORT, an error is being raised on the client and causing the rollback. If for some horrible reason you can't avoid inserting duplicates, you ought to be able to trap the error on the client and ignore it.

Class2 class2 = new Class2();

Instead of calling the main, perhaps you should call individual methods where and when you need them.

When you zip() together three lists containing 20 elements each, the result has twenty elements. Each element is a three-tuple.

See for yourself:

In [1]: a = b = c = range(20)

In [2]: zip(a, b, c)
Out[2]: 
[(0, 0, 0),
 (1, 1, 1),
 ...
 (17, 17, 17),
 (18, 18, 18),
 (19, 19, 19)]

To find out how many elements each tuple contains, you could examine the length of the first element:

In [3]: result = zip(a, b, c)

In [4]: len(result[0])
Out[4]: 3

Of course, this won't work if the lists were empty to start with.

In your Case you can write the following jquery code:

$(document).ready(function(){

   $('.staff_on_site').click(function(){

     var rBtnVal = $(this).val();

     if(rBtnVal == "yes"){
         $("#no_of_staff").attr("readonly", false); 
     }
     else{ 
         $("#no_of_staff").attr("readonly", true); 
     }
   });
});

Here is the Fiddle: http://jsfiddle.net/P4QWx/3/

Neither <iostream> nor <iostream.h> are standard C header files. Your code is meant to be C++, where <iostream> is a valid header. Use g++ (and a .cpp file extension) for C++ code.

Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream> and using namespace std;, and replace cout << endl; with putchar('\n');... I advise compiling using C99 (eg. gcc -std=c99)

Keeping it simple:

use master
select DB.name, F.physical_name from sys.databases DB join sys.master_files F on DB.database_id=F.database_id

this will return all databases with associated files

There is no "standard place" for a sqlite database. The file's location is specified to the library, and may be in your home directory, in the invoking program's folder, or any other place.

If it helps, sqlite databases are, by convention, named with a .db file extension.

Just adding to all the fine answers, my version with decoration:

from __future__ import print_function
import six

def classrep(rep):
    def decorate(cls):
        class RepMetaclass(type):
            def __repr__(self):
                return rep

        class Decorated(six.with_metaclass(RepMetaclass, cls)):
            pass

        return Decorated
    return decorate


@classrep("Wahaha!")
class C(object):
    pass

print(C)

stdout:

Wahaha!

The down sides:

1. You can't declare C without a super class (no class C:)
2. C instances will be instances of some strange derivation, so it's probably a good idea to add a __repr__ for the instances as well.

If you're like me and no so into C++ purism, here's an old skool hybrid. There's some advantage when strings are more than a handful of characters, as most memcmp implementations compare machine words when possible.

You need to be in control of the character set. For example, if this approach is used with utf-8 or wchar type, there's some disadvantage as it won't support character mapping - e.g., when two or more characters are logically identical.

bool starts_with(std::string const & value, std::string const & prefix)
{
    size_t valueSize = value.size();
    size_t prefixSize = prefix.size();

    if (prefixSize > valueSize)
    {
        return false;
    }

    return memcmp(value.data(), prefix.data(), prefixSize) == 0;
}


bool ends_with(std::string const & value, std::string const & suffix)
{
    size_t valueSize = value.size();
    size_t suffixSize = suffix.size();

    if (suffixSize > valueSize)
    {
        return false;
    }

    const char * valuePtr = value.data() + valueSize - suffixSize;

    return memcmp(valuePtr, suffix.data(), suffixSize) == 0;
}

It's perfectly safe as long as you always access the values through the struct via the . (dot) or -> notation.

What's not safe is taking the pointer of unaligned data and then accessing it without taking that into account.

Also, even though each item in the struct is known to be unaligned, it's known to be unaligned in a particular way, so the struct as a whole must be aligned as the compiler expects or there'll be trouble (on some platforms, or in future if a new way is invented to optimise unaligned accesses).

I have just taken the Schwartzian transform depicted above and made as function. It takes an array, the sorting function and a boolean as input:

      array[i] = [].concat(f.call(o,o,i),o);

    array.sort(function(a,b){
      for (var i=0,len=a.length;i<len;++i){
        if (a[i]!=b[i]) return a[i]<b[i]?asc?-1:1:1;
      }
      return 0;
    });
    for (var i=array.length;i;){
      array[--i]=array[i][array[i].length-1];

    return array;

I think there is a simpler way to make excel wait till the refresh is done, without having to set the Background Query property to False. Why mess with people's preferences right?

Excel 2010 (and later) has this method called CalculateUntilAsyncQueriesDone and all you have to do it call it after you have called the RefreshAll method. Excel will wait till the calculation is complete.

ThisWorkbook.RefreshAll
Application.CalculateUntilAsyncQueriesDone

I usually put these things together to do a master full calculate without interruption, before sending my models to others. Something like this:

ThisWorkbook.RefreshAll
Application.CalculateUntilAsyncQueriesDone
Application.CalculateFullRebuild
Application.CalculateUntilAsyncQueriesDone

SELECT CONCAT (zipcode, ' - ', city, ', ', state) AS COMBINED FROM TABLE

It's possible but not all that easy, to create a hybrid native/managed assembly in C#. Were you using C++ instead it'd be a lot easier, as the Visual C++ compiler can create hybrid assemblies as easily as anything else.

Unless you have a strict requirement to produce a hybrid assembly, I'd agree with MusiGenesis that this isn't really worth the trouble to do with C#. If you need to do it, perhaps look at moving to C++/CLI instead.

A method i often use to scroll a container to its contents.

/**
@param {HTMLElement} container : element scrolled.
@param {HTMLElement} target : element where to scroll.
@param {number} [offset] : scroll back by offset
*/
var scrollAt=function(container,target,offset){
    if(container.contains(target)){
        var ofs=[0,0];
        var tmp=target;
        while (tmp!==container) {
            ofs[0]+=tmp.offsetWidth;
            ofs[1]+=tmp.offsetHeight;
            tmp=tmp.parentNode;
        }
        container.scrollTop = Math.max(0,ofs[1]-(typeof(offset)==='number'?offset:0));
    }else{
        throw('scrollAt Error: target not found in container');
    }
};

if your whish to override globally, you could also do :

HTMLElement.prototype.scrollAt=function(target,offset){
    if(this.contains(target)){
        var ofs=[0,0];
        var tmp=target;
        while (tmp!==this) {
            ofs[0]+=tmp.offsetWidth;
            ofs[1]+=tmp.offsetHeight;
            tmp=tmp.parentNode;
        }
        container.scrollTop = Math.max(0,ofs[1]-(typeof(offset)==='number'?offset:0));
    }else{
        throw('scrollAt Error: target not found in container');
    }
};

The maven dependency plugin can potentially solve your problem.

If you have a pom with all your project dependencies specified, all you would need to do is run

mvn dependency:copy-dependencies

and you will find the target/dependencies folder filled with all the dependencies, including transitive.

Adding Gustavo's answer from below: To download the dependency sources, you can use

mvn dependency:copy-dependencies -Dclassifier=sources

I'm using Android Studio 3.0.1 and if the above answer doesn't work for you, try to change the icon type into Legacy and select Shape to None, the default one is Adaptive and Legacy.

Note: Some device has installed a launcher with automatically adding white background in icon, that's normal.

Although the provided answers do work for a specific module, they won't reload submodules, as noted in This answer:

If a module imports objects from another module using from ... import ..., calling reload() for the other module does not redefine the objects imported from it — one way around this is to re-execute the from statement, another is to use import and qualified names (module.*name*) instead.

However, if using the __all__ variable to define the public API, it is possible to automatically reload all publicly available modules:

# Python >= 3.5
import importlib
import types


def walk_reload(module: types.ModuleType) -> None:
    if hasattr(module, "__all__"):
        for submodule_name in module.__all__:
            walk_reload(getattr(module, submodule_name))
    importlib.reload(module)


walk_reload(my_module)

The caveats noted in the previous answer are still valid though. Notably, modifying a submodule that is not part of the public API as described by the __all__ variable won't be affected by a reload using this function. Similarly, removing an element of a submodule won't be reflected by a reload.

I know this is 8 years old, but no one seems to have actually read and answered the question.

You can call .values() on a dict to get a list of the inner dicts and thus access them by index.

>>> mydict = {
...  'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
...  'Grapes':{'Arabian':'25','Indian':'20'} }

>>>mylist = list(mydict.values())
>>>mylist[0]
{'American':'16', 'Mexican':10, 'Chinese':5},
>>>mylist[1]
{'Arabian':'25','Indian':'20'}

>>>myInnerList1 = list(mylist[0].values())
>>>myInnerList1
['16', 10, 5]
>>>myInnerList2 = list(mylist[1].values())
>>>myInnerList2
['25', '20']

In Netbeans you can right click on the project and run it, but in IntelliJ IDEA you have to select the index.jsp file or the welcome file to run the project.

this is because Netbeans generate the following tag in web.xml and IntelliJ do not.

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

I upload expansion code to show photo by android camera on html as normal on some img tag with right rotaion, especially for img tag whose width is wider than height. I know this code is ugly but you don't need to install any other packages. (I used above code to obtain exif rotation value, Thank you.)

function getOrientation(file, callback) {
  var reader = new FileReader();
  reader.onload = function(e) {

    var view = new DataView(e.target.result);
    if (view.getUint16(0, false) != 0xFFD8) return callback(-2);
    var length = view.byteLength, offset = 2;
    while (offset < length) {
      var marker = view.getUint16(offset, false);
      offset += 2;
      if (marker == 0xFFE1) {
        if (view.getUint32(offset += 2, false) != 0x45786966) return callback(-1);
        var little = view.getUint16(offset += 6, false) == 0x4949;
        offset += view.getUint32(offset + 4, little);
        var tags = view.getUint16(offset, little);
        offset += 2;
        for (var i = 0; i < tags; i++)
          if (view.getUint16(offset + (i * 12), little) == 0x0112)
            return callback(view.getUint16(offset + (i * 12) + 8, little));
      }
      else if ((marker & 0xFF00) != 0xFF00) break;
      else offset += view.getUint16(offset, false);
    }
    return callback(-1);
  };
  reader.readAsArrayBuffer(file);
}

    }
}


function changeWidthAndHeight(elem){
    var e = $(elem)
    var width = e.css('width')
    var height = e.css('height')
    e.css('width', height)
    e.css('height', width)
    e.css('margin-top', ((getPxInt(height) - getPxInt(width))/2).toString() + 'px')
    e.css('margin-left', ((getPxInt(width) - getPxInt(height))/2).toString() + 'px')
}

function changeWidthAndHeightWithOutMargin(elem){
    var e = $(elem)
    var width = e.css('width')
    var height = e.css('height')
    e.css('width', height)
    e.css('height', width)

function getPxInt(pxValue) {
    return parseInt(pxValue.trim("px"))
}

function isIPhone(){
    return (
        (navigator.platform.indexOf("iPhone") != -1) ||
        (navigator.platform.indexOf("iPod") != -1)
    );
}

and then use such as

$("#banner-img").change(function () {
    var reader = new FileReader();
    getOrientation(this.files[0], function(orientation) {
        rotate($('#banner-img-preview'), orientation, 1)
    });

    reader.onload = function (e) {
        $('#banner-img-preview').attr('src', e.target.result)
        $('#banner-img-preview').css('display', 'inherit')

    };

    // read the image file as a data URL.
    reader.readAsDataURL(this.files[0]);

});

Here's another way to do this:

- name: my command
  command: echo stuff
  when: "'groupname' not in group_names"

group_names is a magic variable as documented here: https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#accessing-information-about-other-hosts-with-magic-variables :

group_names is a list (array) of all the groups the current host is in.

parag-chauhan and devrim answers are perfect, but i change the onActivityResult without cursor, and it makes the code much more better.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && data != null) {
        Uri selectedImage = data.getData();
        try {
           ImageView imageView = (ImageView) findViewById(R.id.imgView);
           imageView.setImageBitmap(getScaledBitmap(selectedImage,800,800));
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}

private Bitmap getScaledBitmap(Uri selectedImage, int width, int height) throws FileNotFoundException {
    BitmapFactory.Options sizeOptions = new BitmapFactory.Options();
    sizeOptions.inJustDecodeBounds = true;
    BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, sizeOptions);

    int inSampleSize = calculateInSampleSize(sizeOptions, width, height);

    sizeOptions.inJustDecodeBounds = false;
    sizeOptions.inSampleSize = inSampleSize;

    return BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, sizeOptions);
}

private int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) {
    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {
        // Calculate ratios of height and width to requested one
        final int heightRatio = Math.round((float) height / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
    }
    return inSampleSize;
}

Just adding to this that in ES6 because of arrow functions you shouldn't need to do this because they capture the this value.

I found too simple hack just do this add new element in AndroidManifest as:-

<activity android:name=".activityName"
          android:label="@string/app_name"
          android:noHistory="true"/>

the android:noHistory will clear your unwanted activity from Stack.

Not tested, but something like this:

var now = new Date();
var str = now.getUTCFullYear().toString() + "/" +
          (now.getUTCMonth() + 1).toString() +
          "/" + now.getUTCDate() + " " + now.getUTCHours() +
          ":" + now.getUTCMinutes() + ":" + now.getUTCSeconds();

Of course, you'll need to pad the hours, minutes, and seconds to two digits or you'll sometimes get weird looking times like "2011/12/2 19:2:8."

I had this problem on Windows 8, but I solved the problem by updating all of Android Studio's plugins with the SDK Manager, then restarting the computer.

Sticking to the method you are using to insert it, use

list[:0] = ['foo']

http://docs.python.org/release/2.6.6/library/stdtypes.html#mutable-sequence-types

data-interval="false"

Add this to the corresponding div ...

As Lattyware said, there is a difference between Python2 & Python3 that leads to this error:

With Python2, int(str(5/2)) gives you 2. With Python3, the same gives you: ValueError: invalid literal for int() with base 10: '2.5'

If you need to convert some string that could contain float instead of int, you should always use the following ugly formula:

int(float(myStr))

As float('3.0') and float('3') give you 3.0, but int('3.0') gives you the error.

Content Editable, HTML or any other DOM element Selections

If you are trying to insert at caret on a <div contenteditable="true">, this becomes much more difficult, especially if there are children within the editable container.

I have had really great luck using the Rangy library:

• GIT: https://github.com/timdown/rangy
• NPM: https://www.npmjs.com/package/rangy

It has a ton of great features such as:

• Save Position or Selection
• Then later, Restore the Position or Selection
• Get selection HTML or Plaintext
• Among many others

The online demo was not working last I checked, however the repo has working demos. To get started, simple download the Repo from Git or NPM, then open ./rangy/demos/index.html

It makes working with caret pos and text selection a breeze!

I dont think anyone has answered the question correctly.So, for anyone else who has the same question, this should help :

Step 1 Go to Build>Generate Signed APK>Next (module selected would be your module , most often called "app")

Step 2 Click on create new

Step 3 Basically, fill in the form with the required details. The confusing bit it is where it asks for a Key Store Path. Click on the icon on the right with the 3 dots ("..."), which will open up a navigator window asking you to navigate and select a .jks file.Navigate to a folder where you want your keystore file saved and then at the File Name box at the bottom of that window, simply enter a name of your liking and the OK button will be clickable now. What is happening is that the window isnt really asking you chose a .jks file but rather it wants you to give it the location and name that you want it to have.

Step 4 Click on Next and then select Release and Voila ! you are done.

you just provide one <folder> argument to npm install, argument should point toward the local folder instead of the package name:

npm install /path

Try something like this

select Cast((SPGI09_EARLY_OVER_T – (SPGI09_OVER_WK_EARLY_ADJUST_T) / (SPGI09_EARLY_OVER_T + SPGR99_LATE_CM_T  + SPGR99_ON_TIME_Q)) as varchar(20) + '%' as percentageAmount
from CSPGI09_OVERSHIPMENT

I presume the value is a representation in percentage - if not convert it to a valid percentage total, then add the % sign and convert the column to varchar.

There is no command to do it (like you would do it with MySQL for instance). The number of Redis databases is fixed, and set in the configuration file. By default, you have 16 databases. Each database is identified by a number (not a name).

You can use the following command to know the number of databases:

CONFIG GET databases
1) "databases"
2) "16"

You can use the following command to list the databases for which some keys are defined:

INFO keyspace
# Keyspace
db0:keys=10,expires=0
db1:keys=1,expires=0
db3:keys=1,expires=0

Please note that you are supposed to use the "redis-cli" client to run these commands, not telnet. If you want to use telnet, then you need to run these commands formatted using the Redis protocol.

For instance:

*2
$4
INFO
$8
keyspace

$79
# Keyspace
db0:keys=10,expires=0
db1:keys=1,expires=0
db3:keys=1,expires=0

You can find the description of the Redis protocol here: http://redis.io/topics/protocol

If any one want it in Java, Here is my Answer, For this you have to call Another Thread.

If it is all a list of lists, you could modify sir @Raymond's answer

L = [ [None], [123], [None], [151] ] no_none_val = list(filter(None.__ne__, [x[0] for x in L] ) ) for python 2 however

no_none_val = [x[0] for x in L if x[0] is not None] """ Both returns [123, 151]"""

<< list_indice[0] for variable in List if variable is not None >>

Alternate form of the answer by @rumpel

with open(filename, 'w'): pass

public List<String> getAllData(String email)
{

    db = this.getReadableDatabase();
    String[] projection={email};

    List<String> list=new ArrayList<>();

    Cursor cursor = db.query(TABLE_USER, //Table to query
            null,    //columns to return
            "user_email=?",        //columns for the WHERE clause
            projection,        //The values for the WHERE clause
            null,       //group the rows
            null,       //filter by row groups
            null);
    //  cursor.moveToFirst();

    if (cursor.moveToFirst()) {
        do {

            list.add(cursor.getString(cursor.getColumnIndex("user_id")));
            list.add(cursor.getString(cursor.getColumnIndex("user_name")));
            list.add(cursor.getString(cursor.getColumnIndex("user_email")));
            list.add(cursor.getString(cursor.getColumnIndex("user_password")));
            // cursor.moveToNext();

        } while (cursor.moveToNext());
    }
    return list;
}

Perhaps replace is what you are looking for:

> x = c(3, 2, 1, 0, 4, 0)
> replace(x, x==0, 1)
[1] 3 2 1 1 4 1

Or, if you don't have x (any specific reason why not?):

replace(c(3, 2, 1, 0, 4, 0), c(3, 2, 1, 0, 4, 0)==0, 1)

Many people are familiar with gsub, so you can also try either of the following:

as.numeric(gsub(0, 1, x))
as.numeric(gsub(0, 1, c(3, 2, 1, 0, 4, 0)))

Update

After reading the comments, perhaps with is an option:

with(data.frame(x = c(3, 2, 1, 0, 4, 0)), replace(x, x == 0, 1))

You can do something like this.

 List<Map<String, Object>> mapList = jdbctemplate.queryForList(query));
    return mapList.stream().collect(Collectors.toMap(k -> (Long) k.get("userid"), k -> (String) k.get("username")));

Output:

 {
  1: "abc",
  2: "def",
  3: "ghi"
}
