If you're using V4.1, and according to their docs, don't assign .table-responsive directly to the table. The table should be .table and if you want it to be horizontally scrollable (responsive) add it inside a .table-responsive container (a <div>, for instance).

Responsive tables allow tables to be scrolled horizontally with ease. Make any table responsive across all viewports by wrapping a .table with .table-responsive.

<div class="table-responsive">
  <table class="table">
  ...
  </table>
</div>

doing that, no extra css is needed.

In the OP's code, .table-responsive can be used alongside with the .col-md-12 on the outside .

You don't need jQuery to do this. Here's an ES2015 solution:

// Get all input fields
const inputs = document.querySelectorAll('#register input');

// Get only the required ones
const requiredFields = Array.from(inputs).filter(input => input.required);

// Do your stuff with the required fields
requiredFields.forEach(field => /* do what you want */);

Or you could just use the :required selector:

Array.from(document.querySelectorAll('#register input:required'))
    .forEach(field => /* do what you want */);

Procedure to get Python Working in XCode 7

Step 1: Setup your Project with a External Build System

Step 1.1: Edit the Project Scheme

Step 2: Specify Python as the executable for the project (shift-command-g) the path should be /usr/bin/python

Step 3: Specify your custom working directory

Step 4: Specify your command line arguments to be the name of your python file. (in this example "test.py")

Step 5: Thankfully thats it!

(debugging can't be added until OSX supports a python debugger?)

Multiply the input by Math.PI/180 to convert from degrees to radians before calling the system trig functions.

You could also define your own functions:

function sinDegrees(angleDegrees) {
    return Math.sin(angleDegrees*Math.PI/180);
};

and so on.

In this post I described possible solution for Solaris case when neither SO_NOSIGPIPE nor MSG_NOSIGNAL is available.

Instead, we have to temporarily suppress SIGPIPE in the current thread that executes library code. Here's how to do this: to suppress SIGPIPE we first check if it is pending. If it does, this means that it is blocked in this thread, and we have to do nothing. If the library generates additional SIGPIPE, it will be merged with the pending one, and that's a no-op. If SIGPIPE is not pending then we block it in this thread, and also check whether it was already blocked. Then we are free to execute our writes. When we are to restore SIGPIPE to its original state, we do the following: if SIGPIPE was pending originally, we do nothing. Otherwise we check if it is pending now. If it does (which means that out actions have generated one or more SIGPIPEs), then we wait for it in this thread, thus clearing its pending status (to do this we use sigtimedwait() with zero timeout; this is to avoid blocking in a scenario where malicious user sent SIGPIPE manually to a whole process: in this case we will see it pending, but other thread may handle it before we had a change to wait for it). After clearing pending status we unblock SIGPIPE in this thread, but only if it wasn't blocked originally.

Example code at https://github.com/kroki/XProbes/blob/1447f3d93b6dbf273919af15e59f35cca58fcc23/src/libxprobes.c#L156

Unlike many of the other answers, this solution uses completely free software.

Firstly, create a file called Resources.rc like this:

VS_VERSION_INFO VERSIONINFO
    FILEVERSION    1,0,0,0
    PRODUCTVERSION 1,0,0,0
{
    BLOCK "StringFileInfo"
    {
        BLOCK "040904b0"
        {
            VALUE "CompanyName",        "ACME Inc.\0"
            VALUE "FileDescription",    "MyProg\0"
            VALUE "FileVersion",        "1.0.0.0\0"
            VALUE "LegalCopyright",     "© 2013 ACME Inc. All Rights Reserved\0"
            VALUE "OriginalFilename",   "MyProg.exe\0"
            VALUE "ProductName",        "My Program\0"
            VALUE "ProductVersion",     "1.0.0.0\0"
        }
    }
    BLOCK "VarFileInfo"
    {
        VALUE "Translation", 0x409, 1200
    }
}

Next, use GoRC to compile it to a .res file using:

GoRC /fo Resources.res Resources.rc

^{(see my comment below for a mirror of GoRC.exe)}

Then use Resource Hacker in CLI mode to add it to an existing .exe:

ResHacker -add MyProg.exe, MyProg.exe, Resources.res,,,

That's it!

Can you set the ActionBar before you set the Contient View? This order would be better:

 @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ActionBar actionBar =getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);            
  }

Running the following experiment the pythonic way:

[s + mystring for s in mylist]

seems to be ~35% faster than the obvious use of a for loop like this:

i = 0
for s in mylist:
    mylist[i] = s+mystring
    i = i + 1

Experiment

import random
import string
import time

mystring = '/test/'

l = []
ref_list = []

for i in xrange( 10**6 ):
    ref_list.append( ''.join(random.choice(string.ascii_lowercase) for i in range(10)) )

for numOfElements in [5, 10, 15 ]:

    l = ref_list*numOfElements
    print 'Number of elements:', len(l)

    l1 = list( l )
    l2 = list( l )

    # Method A
    start_time = time.time()
    l2 = [s + mystring for s in l2]
    stop_time = time.time()
    dt1 = stop_time - start_time
    del l2
    #~ print "Method A: %s seconds" % (dt1)

    # Method B
    start_time = time.time()
    i = 0
    for s in l1:
        l1[i] = s+mystring
        i = i + 1
    stop_time = time.time()
    dt0 = stop_time - start_time
    del l1
    del l
    #~ print "Method B: %s seconds" % (dt0)

    print 'Method A is %.1f%% faster than Method B' % ((1 - dt1/dt0)*100)

Results

Number of elements: 5000000
Method A is 38.4% faster than Method B
Number of elements: 10000000
Method A is 33.8% faster than Method B
Number of elements: 15000000
Method A is 35.5% faster than Method B

hope it's worked for you:

File yourFile = new File(Environment.getExternalStorageDirectory(), "textarabics.txt");

This will give u sdcard path:

File path = Environment.getExternalStorageDirectory();

Try this:

String pathName = "/mnt/";

or try this:

String pathName = "/storage/";

As you read through the examples below, just keep in mind this difference

true === true // true
"string" === true // false
1 === true // false
{} === true // false

But

Boolean("string") === true // true
Boolean(1) === true // true
Boolean({}) === true // true

1. expect(statement).toBe(true)

Assertion passes when the statement passed to expect() evaluates to true

expect(true).toBe(true) // pass
expect("123" === "123").toBe(true) // pass

In all other cases cases it would fail

expect("string").toBe(true) // fail
expect(1).toBe(true); // fail
expect({}).toBe(true) // fail

Even though all of these statements would evaluate to true when doing Boolean():

So you can think of it as 'strict' comparison

2. expect(statement).toBeTrue()

This one does exactly the same type of comparison as .toBe(true), but was introduced in Jasmine recently in version 3.5.0 on Sep 20, 2019

3. expect(statement).toBeTruthy()

toBeTruthy on the other hand, evaluates the output of the statement into boolean first and then does comparison

expect(false).toBeTruthy() // fail
expect(null).toBeTruthy() // fail
expect(undefined).toBeTruthy() // fail
expect(NaN).toBeTruthy() // fail
expect("").toBeTruthy() // fail
expect(0).toBeTruthy() // fail

And IN ALL OTHER CASES it would pass, for example

expect("string").toBeTruthy() // pass
expect(1).toBeTruthy() // pass
expect({}).toBeTruthy() // pass

Based on @DCDC's answer

Here is an answer coming right from the libc6! Taking a look at /usr/include/x86_64-linux-gnu/bits/byteswap.h, I found the trick you were looking for.

A few critics of previous solutions:

• Kip's solution does not permit evaluating to an expression, which is in the end often needed.
• coppro's solution does not permit assigning a variable as the expressions are separate, but can evaluate to an expression.
• Steve Jessop's solution uses the C++11 auto keyword, that's fine, but feel free to use the known/expected type instead.

The trick is to use both the (expr,expr) construct and a {} scope:

#define MACRO(X,Y) \
  ( \
    { \
      register int __x = static_cast<int>(X), __y = static_cast<int>(Y); \
      std::cout << "1st arg is:" << __x << std::endl; \
      std::cout << "2nd arg is:" << __y << std::endl; \
      std::cout << "Sum is:" << (__x + __y) << std::endl; \
      __x + __y; \
    } \
  )

Note the use of the register keyword, it's only a hint to the compiler. The X and Y macro parameters are (already) surrounded in parenthesis and casted to an expected type. This solution works properly with pre- and post-increment as parameters are evaluated only once.

For the example purpose, even though not requested, I added the __x + __y; statement, which is the way to make the whole bloc to be evaluated as that precise expression.

It's safer to use void(); if you want to make sure the macro won't evaluate to an expression, thus being illegal where an rvalue is expected.

However, the solution is not ISO C++ compliant as will complain g++ -pedantic:

warning: ISO C++ forbids braced-groups within expressions [-pedantic]

In order to give some rest to g++, use (__extension__ OLD_WHOLE_MACRO_CONTENT_HERE) so that the new definition reads:

#define MACRO(X,Y) \
  (__extension__ ( \
    { \
      register int __x = static_cast<int>(X), __y = static_cast<int>(Y); \
      std::cout << "1st arg is:" << __x << std::endl; \
      std::cout << "2nd arg is:" << __y << std::endl; \
      std::cout << "Sum is:" << (__x + __y) << std::endl; \
      __x + __y; \
    } \
  ))

In order to improve my solution even a bit more, let's use the __typeof__ keyword, as seen in MIN and MAX in C:

#define MACRO(X,Y) \
  (__extension__ ( \
    { \
      __typeof__(X) __x = (X); \
      __typeof__(Y) __y = (Y); \
      std::cout << "1st arg is:" << __x << std::endl; \
      std::cout << "2nd arg is:" << __y << std::endl; \
      std::cout << "Sum is:" << (__x + __y) << std::endl; \
      __x + __y; \
    } \
  ))

Now the compiler will determine the appropriate type. This too is a gcc extension.

Note the removal of the register keyword, as it would the following warning when used with a class type:

warning: address requested for ‘__x’, which is declared ‘register’ [-Wextra]

target="_blank" attribute will do the job. Just don't forget to add rel="noopener noreferrer" to solve the potential vulnerability. More on that here: https://dev.to/ben/the-targetblank-vulnerability-by-example

<a href="https://www.google.com/" target="_blank" rel="noopener noreferrer">Searcher</a>

property_exists( mixed $class , string $property )

if (property_exists($ob, 'a')) 

isset( mixed $var [, mixed $... ] )

if (isset($ob->a))

isset() will return false if property is null

Example 1:

$ob->a = null
var_dump(isset($ob->a)); // false

Example 2:

class Foo
{
   public $bar = null;
}

$foo = new Foo();

var_dump(property_exists($foo, 'bar')); // true
var_dump(isset($foo->bar)); // false

Take a look at this forum http://htmlcoderhelper.com/why-is-using-a-wild-card-with-a-java-import-statement-bad/. Theres a discussion on how using wildcards can lead to conflicts if you add new classes to the packages and if there are two classes with the same name in different packages where only one of them will be imported.

Update

List<Integer> i = new ArrayList<Integer>(Arrays.asList(0,1,2,3,4,5,6,7,8,9,10));
List<Integer> j = new ArrayList<Integer>();

You need to specify the type for array list or the compiler will give that warning because it cannot identify that you are using the list in a type safe way.

For me the most elegant and faster way to achieve it is:

function hasClass(el,cl){
   return !!el.className && !!el.className.match(new RegExp('\\b('+cl+')\\b'));
}

JSON is a format that encodes objects in a string. Serialization means to convert an object into that string, and deserialization is its inverse operation (convert string -> object).

When transmitting data or storing them in a file, the data are required to be byte strings, but complex objects are seldom in this format. Serialization can convert these complex objects into byte strings for such use. After the byte strings are transmitted, the receiver will have to recover the original object from the byte string. This is known as deserialization.

Say, you have an object:

{foo: [1, 4, 7, 10], bar: "baz"}

serializing into JSON will convert it into a string:

'{"foo":[1,4,7,10],"bar":"baz"}'

which can be stored or sent through wire to anywhere. The receiver can then deserialize this string to get back the original object. {foo: [1, 4, 7, 10], bar: "baz"}.

If you want to access referrer and user-agent, those are available to client-side Javascript, but not by accessing the headers directly.

To retrieve the referrer, use document.referrer.
To access the user-agent, use navigator.userAgent.

As others have indicated, the HTTP headers are not available, but you specifically asked about the referer and user-agent, which are available via Javascript.

From the looks of it you could do the following on your docker-compose.yml

volumes:
    - ./:/app

Where ./ is the host directory, and /app is the target directory for the containers.

Below code worked for me:

<input #fileInput type="file" id="avatar" accept="application/pdf,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document" />

SQLDataReaders are forward-only. You're essentially doing this:

count++;  // initially 1
.DataBind(); //consuming all the records

//next iteration on
.Read()
//we've now come to end of resultset, thanks to the DataBind()
//count is still 1 

You could do this instead:

if (reader.HasRows)
{
    rep.DataSource = reader;
    rep.DataBind();
}
int count = rep.Items.Count; //somehow count the num rows/items `rep` has.

If you're already using the tidyverse, there are a few solution depending on the exact situation.

Basic if you know it's all numbers and doesn't have NAs

library(dplyr)

# solution
dataset %>% mutate_if(is.character,as.numeric)

Test cases

df <- data.frame(
  x1 = c('1','2','3'),
  x2 = c('4','5','6'),
  x3 = c('1','a','x'), # vector with alpha characters
  x4 = c('1',NA,'6'), # numeric and NA
  x5 = c('1',NA,'x'), # alpha and NA
  stringsAsFactors = F)

# display starting structure
df %>% str()

Convert all character vectors to numeric (could fail if not numeric)

df %>%
  select(-x3) %>% # this removes the alpha column if all your character columns need converted to numeric
  mutate_if(is.character,as.numeric) %>%
  str()

Check if each column can be converted. This can be an anonymous function. It returns FALSE if there is a non-numeric or non-NA character somewhere. It also checks if it's a character vector to ignore factors. na.omit removes original NAs before creating "bad" NAs.

is_all_numeric <- function(x) {
  !any(is.na(suppressWarnings(as.numeric(na.omit(x))))) & is.character(x)
}
df %>% 
  mutate_if(is_all_numeric,as.numeric) %>%
  str()

If you want to convert specific named columns, then mutate_at is better.

df %>% mutate_at('x1', as.numeric) %>% str()

The @ symbol allows you to use reserved word. For example:

int @class = 15;

The above works, when the below wouldn't:

int class = 15;

For CMD one line LF-only:

powershell -NoProfile -command "((Get-Content 'prueba1.txt') -join \"`n\") + \"`n\" | Set-Content -NoNewline 'prueba1.txt'"

so you can create a .bat

http://msdn.microsoft.com/en-us/library/bb507946:

"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
    <sheets>
        <sheet name="MySheet1" sheetId="1" r:id="rId1" /> 
        <sheet name="MySheet2" sheetId="2" r:id="rId2" /> 
    </sheets>
</workbook>

The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" ?> 
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
    <sheetData>
        <row r="1">

Another alternative is to use ssh-ident, to manage your ssh identities.

It automatically loads and uses different keys based on your current working directory, ssh options, and so on... which means you can easily have a work/ directory and private/ directory that transparently end up using different keys and identities with ssh.

Just rename the .war into .jar and unzip it using Winrar (or any other archive manager).

Another easy solution to disable swiping at specific page (in this example, page 2):

int PAGE = 2;
viewPager.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
        if (viewPager.getCurrentItem() == PAGE) {
                viewPager.setCurrentItem(PAGE-1, false);
                viewPager.setCurrentItem(PAGE, false);
                return  true;
        }
        return false;

An IDE which supports Android development is Processing for Android: http://wiki.processing.org/w/Android. Processing is its own language but it's easy to learn. Processing for Android requires the JDK and Android SDK to be installed but runs on its own. It runs on Linux, Mac OSX and Windows (on a side note: one can develop a desktop app in Processing and then compile it to target any of these operating systems). Its development is ongoing but it works. It's especially good for quickly sketching up an idea and running it on your Android phone (even if you plan to develop it further in another IDE).

There is an active support forum here: http://forum.processing.org/android-processing.

Use a Backbone.js or AngularJS-like JavaScript framework for UI design and fetch the data using a REST API. This will remove the Java dependency from the UI completely.

Generally, this will be dependent on the interface the connection is using. You can probably use an ioctl() to get the MTU, and if it is ethernet, you can usually get the maximum packet size by subtracting the size of the hardware header from that, which is 14 for ethernet with no VLAN.

This is only the case if the MTU is at least that large across the network. TCP may use path MTU discovery to reduce your effective MTU.

The question is, why do you care?

W3Schools have a nice article on this subject.

Scripts in <head>

Scripts to be executed when they are called, or when an event is triggered, are placed in functions.

Put your functions in the head section, this way they are all in one place, and they do not interfere with page content.

Scripts in <body>

If you don't want your script to be placed inside a function, or if your script should write page content, it should be placed in the body section.

You may want to have a look at https://isocpp.org/wiki/faq/pointers-to-members#fnptr-vs-memfnptr-types, especially [33.1] Is the type of "pointer-to-member-function" different from "pointer-to-function"?

One way you can perform this operation for all the values 1 through 7 at once is to use the function ACCUMARRAY:

>> M = randi(7,1500,1);  %# Some random sample data with the values 1 through 7
>> dayCounts = accumarray(M,1)  %# Will return a 7-by-1 vector

dayCounts =

   218       %# Number of Sundays
   200       %# Number of Mondays
   213       %# Number of Tuesdays
   220       %# Number of Wednesdays
   234       %# Number of Thursdays
   219       %# Number of Fridays
   196       %# Number of Saturdays

In .NET Core I played with all upper answers - but without any success. I made changes a lot in DB structure and every time added new migration attempting to update-database, but received the same error.

Then I started to remove-migration one by one until Package Manager Console threw me exception:

The migration '20170827183131_***' has already been applied to the database

After that, I added new migration (add-migration) and update-database successfully

So my suggestion would be: clear out all your temp migrations, until your current DB state.

Use regular expression:

String s="your1string2contain3with4number";
int i=Integer.parseInt(s.replaceAll("[\\D]", ""));

output: i=1234;

If you need first number combination then you should try below code:

String s="abc123xyz456";
int i=NumberFormat.getInstance().parse(s).intValue();

output: i=123;

Here's a flexible method, written in vanilla JS, that allows you to run a CSS selector query over only the direct children of an element:

var count = 0;
function queryChildren(element, selector) {
  var id = element.id,
      guid = element.id = id || 'query_children_' + count++,
      attr = '#' + guid + ' > ',
      selector = attr + (selector + '').replace(',', ',' + attr, 'g');
  var result = element.parentNode.querySelectorAll(selector);
  if (!id) element.removeAttribute('id');
  return result;
}

Try this:

> HISTTIMEFORMAT="%d/%m/%y %T "

> history

You can adjust the format to your liking, of course.

$('form[name="frmSave"]') is correct. You mentioned you thought this would get all children with the name frmsave inside the form; this would only happen if there was a space or other combinator between the form and the selector, eg: $('form [name="frmSave"]');

$('form[name="frmSave"]') literally means find all forms with the name frmSave, because there is no combinator involved.

The better way I found here:

Dream.In.Code

action="javascript: void(0)" or action="return false;" (doesn't work on me)

see the Matlab GEOMETRY toolbox in the following website: http://people.sc.fsu.edu/~jburkardt/m_src/geometry/geometry.html

ctrl+f and type "segment" to find line segment related functions. the functions "segment_point_dist_2d.m" and "segment_point_dist_3d.m" are what you need.

The GEOMETRY codes are available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version.

You normally use a tool like pip to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.

For this to work, you do need to install the wheel package:

pip install wheel

You can then tell pip to install the project (and it'll download the wheel if available), or the wheel file directly:

pip install project_name  # discover, download and install
pip install wheel_file.whl  # directly install the wheel

The wheel module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:

python -m wheel install wheel_file.whl

Also see the wheel project documentation.

See some of the answers to my similar question why-cant-i-push-from-a-shallow-clone and the link to the recent thread on the git list.

Ultimately, the 'depth' measurement isn't consistent between repos, because they measure from their individual HEADs, rather than (a) your Head, or (b) the commit(s) you cloned/fetched, or (c) something else you had in mind.

The hard bit is getting one's Use Case right (i.e. self-consistent), so that distributed, and therefore probably divergent repos will still work happily together.

It does look like the checkout --orphan is the right 'set-up' stage, but still lacks clean (i.e. a simple understandable one line command) guidance on the "clone" step. Rather it looks like you have to init a repo, set up a remote tracking branch (you do want the one branch only?), and then fetch that single branch, which feels long winded with more opportunity for mistakes.

Edit: For the 'clone' step see this answer

I take a different view.

A "script" is code that acts upon some system in an external or independent manner and can be removed or disabled without disabling the system itself.

A "program" is code that constitutes a system. The program's code may be written in a modular manner, with good separation of concerns, but the code is fundamentally internal to, and a dependency of, the system itself.

Scripts are often interpreted, but not always. Programs are often compiled, but not always.

You should normally be able to run a php file (after a successful installation) just by running this command:

$ /path/to/php myfile.php // unix way
C:\php\php.exe myfile.php // windows way

You can read more about running PHP in CLI mode here.

It's worth adding that PHP from version 5.4 onwards is able to run a web server on its own. You can do it by running this code in a folder which you want to serve the pages from:

$ php -S localhost:8000

You can read more about running a PHP in a Web Server mode here.

This one-liner works:

var currentDirectory = window.location.pathname.split('/').slice(0, -1).join('/')

My way to do it

$('#table_1').DataTable({
    processing: true,
    serverSide: true,
    ajax: 'customer/data',
    columns: [
        { data: 'id', name: 'id' , width: '50px', class: 'text-right' },
        { data: 'name', name: 'name' width: '50px', class: 'text-right' }
    ]
});

Excel Method

This method is different than many you will see. Others use a loop to write each cell and write the cells with text data type.

This method creates an object array from a DataTable or DataGridView and then writes the array to Excel. This means I can write to Excel without a loop and retain data types.

I extracted this from my library and I think I changed it enough to work with this code only, but more minor tweaking might be necessary. If you get errors just let me know and I'll correct them for you. Normally, I create an instance of my class and call these methods. If you would like to use my library then use this link to download it and if you need help just let me know.

After copying the code to your solution you will use it like this.

In your button code add this and change the names to your controls.

WriteDataGrid("Sheet1", grid)

To open your file after exporting use this line

System.Diagnostics.Process.Start("The location and filename of your file")

In the WriteArray method you'll want to change the line that saves the workbook to where you want to save it. Probably makes sense to add this as a parameter.

I actually don't use this method in my Database program because it's a slow method when you have a lot of rows/columns. I instead create a CSV from the DataGridView. Writing to Excel with Excel Automation is only useful if you need to format the data and cells otherwise you should use CSV. You can use the code after the image for CSV export.

        Dim i As Integer = 1

            If i = 1 Then

Alpine docker image doesn't have bash installed by default. You will need to add following commands to get bash:

RUN apk update && apk add bash

If youre using Alpine 3.3+ then you can just do

RUN apk add --no-cache bash

to keep docker image size small. (Thanks to comment from @sprkysnrky)

Using KeyGenerator would be the preferred method. As Duncan indicated, I would certainly give the key size during initialization. KeyFactory is a method that should be used for pre-existing keys.

OK, so lets get to the nitty-gritty of this. In principle AES keys can have any value. There are no "weak keys" as in (3)DES. Nor are there any bits that have a specific meaning as in (3)DES parity bits. So generating a key can be as simple as generating a byte array with random values, and creating a SecretKeySpec around it.

But there are still advantages to the method you are using: the KeyGenerator is specifically created to generate keys. This means that the code may be optimized for this generation. This could have efficiency and security benefits. It might be programmed to avoid a timing side channel attacks that would expose the key, for instance. Note that it may already be a good idea to clear any byte[] that hold key information as they may be leaked into a swap file (this may be the case anyway though).

Furthermore, as said, not all algorithms are using fully random keys. So using KeyGenerator would make it easier to switch to other algorithms. More modern ciphers will only accept fully random keys though; this is seen as a major benefit over e.g. DES.

Finally, and in my case the most important reason, it that the KeyGenerator method is the only valid way of handling AES keys within a secure token (smart card, TPM, USB token or HSM). If you create the byte[] with the SecretKeySpec then the key must come from memory. That means that the key may be put in the secure token, but that the key is exposed in memory regardless. Normally, secure tokens only work with keys that are either generated in the secure token or are injected by e.g. a smart card or a key ceremony. A KeyGenerator can be supplied with a provider so that the key is directly generated within the secure token.

As indicated in Duncan's answer: always specify the key size (and any other parameters) explicitly. Do not rely on provider defaults as this will make it unclear what your application is doing, and each provider may have its own defaults.

It took me a while to combine everything, make it a bit secure, and have it work with Gmail. I hope this answer saves someone some time.

Create a file with the encrypted server password:

In Powershell, enter the following command (replace myPassword with your actual password):

"myPassword" | ConvertTo-SecureString -AsPlainText -Force | ConvertFrom-SecureString | Out-File "C:\EmailPassword.txt"

Create a powershell script (Ex. sendEmail.ps1):

$User = "[email protected]"
$File = "C:\EmailPassword.txt"
$cred=New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, (Get-Content $File | ConvertTo-SecureString)
$EmailTo = "[email protected]"
$EmailFrom = "[email protected]"
$Subject = "Email Subject" 
$Body = "Email body text" 
$SMTPServer = "smtp.gmail.com" 
$filenameAndPath = "C:\fileIwantToSend.csv"
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom,$EmailTo,$Subject,$Body)
$attachment = New-Object System.Net.Mail.Attachment($filenameAndPath)
$SMTPMessage.Attachments.Add($attachment)
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587) 
$SMTPClient.EnableSsl = $true 
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($cred.UserName, $cred.Password); 
$SMTPClient.Send($SMTPMessage)

Automate with Task Scheduler:

Create a batch file (Ex. emailFile.bat) with the following:

powershell -ExecutionPolicy ByPass -File C:\sendEmail.ps1

Create a task to run the batch file. Note: you must have the task run with the same user account that you used to encrypted the password! (Aka, probably the logged in user)

That's all; you now have a way to automate and schedule sending an email and an attachment with Windows Task Scheduler and Powershell. No 3rd party software and the password is not stored as plain text (though granted, not terribly secure either).

You can also read this article on the level of security this provides for your email password.

Those algorithms are both incorrect because of the comparison:

for( int i = 0; i < elements.length - 1; i++)

or

for(int i = 0; i + 1 < elements.length; i++) {

It's true that the array elements range from 0 to length - 1, but the comparison in that case should be less than or equal to. Those should be:

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

or

for(int i = 0; i <= elements.length - 1; i++) {

or

for(int i = 0; i + 1 <= elements.length; i++) {

The array ["a", "b"] would iterate as:

i = 0 is < 2: elements[0] yields "a"

i = 1 is < 2: elements[1] yields "b"

then exit the loop because 2 is not < 2.

The incorrect examples both exit the loop prematurely and only execute with the first element in this simple case of two elements.

I think you can create a simple SQL query:

$sql="select username from user where id in (select id from idtables)";
$query=$this->db->query($sql);

and then you can use it normally.

Use a custom Listview.

You can also customize how row looks by having a custom background. activity_main.xml

Inflate a custom layout. Use a view holder for smooth scrolling and performance.

http://developer.android.com/training/improving-layouts/smooth-scrolling.html

http://www.youtube.com/watch?v=wDBM6wVEO70. The talk is about listview performance by android developers.

Here is an example of a simple Two-column class:

.two-col {
       -moz-column-count: 2;
       -moz-column-gap: 20px;
       -webkit-column-count: 2;
       -webkit-column-gap: 20px;
}

Of which you would apply to a block of text like so:

<p class="two-col">Text</p>

Not relevant to your example, but you can also get the Bad substitution error in Bash for any substitution syntax that Bash does not recognize. This could be:

• Stray whitespace. E.g. bash -c '${x }'
• A typo. E.g. bash -c '${x;-}'
• A feature that was added in a later Bash version. E.g. bash -c '${x@Q}' before Bash 4.4.

If you have multiple substitutions in the same expression, Bash may not be very helpful in pinpointing the problematic expression. E.g.:

$ bash -c '"${x } multiline string
$y"'
bash: line 1: ${x } multiline string
$y: bad substitution

What is the difference between creating cookies on the server and on the client?

What you are referring to are the 2 ways in which cookies can be directed to be set on the client, which are:

• By server
• By client ( browser in most cases )

By server: The Set-cookie response header from the server directs the client to set a cookie on that particular domain. The implementation to actually create and store the cookie lies in the browser. For subsequent requests to the same domain, the browser automatically sets the Cookie request header for each request, thereby letting the server have some state to an otherwise stateless HTTP protocol. The Domain and Path cookie attributes are used by the browser to determine which cookies are to be sent to a server. The server only receives name=value pairs, and nothing more.

By Client: One can create a cookie on the browser using document.cookie = cookiename=cookievalue. However, if the server does not intend to respond to any random cookie a user creates, then such a cookie serves no purpose.

Are these called server side cookies and client side cookies?

Cookies always belong to the client. There is no such thing as server side cookie.

Is there a way to create cookies that can only be read on the server or on the client?

Since reading cookie values are upto the server and client, it depends if either one needs to read the cookie at all. On the client side, by setting the HttpOnly attribute of the cookie, it is possible to prevent scripts ( mostly Javscript ) from reading your cookies , thereby acting as a defence mechanism against Cookie theft through XSS, but sends the cookie to the intended server only.

Therefore, in most of the cases since cookies are used to bring 'state' ( memory of past user events ), creating cookies on client side does not add much value, unless one is aware of the cookies the server uses / responds to.

Then you can get the register name you are interested in -- very useful for finding platform-specific registers (like NEON Q... on ARM).

Pandas 0.21 now has an axis parameter

The rename method has gained an axis parameter to match most of the rest of the pandas API.

So, in addition to this:

df.rename(columns = {'two':'new_name'})

You can do:

df.rename({'two':'new_name'}, axis=1)

or

df.rename({'two':'new_name'}, axis='columns')

i am very new to this website. I am an undergraduate student, doing my Bachelor Of Computer Application. I am doing a simple program in Visual Studio using C# and I came across the same problem, how to check whether a button is clicked? I wanted to do this,

if(-button1 is clicked-) then
{
this should happen;
}
if(-button2 is clicked-) then
{
this should happen;
}

I didn't know what to do, so I tried searching for the solution in the internet. I got many solutions which didn't help me. So, I tried something on my own and did this,

int i;
private void button1_Click(object sender, EventArgs e)
        {
            i = 1;
            label3.Text = "Principle";
            label4.Text = "Rate";
            label5.Text = "Time";
            label6.Text = "Simple Interest";
        }


private void button2_Click(object sender, EventArgs e)
        {
            i = 2;
            label3.Text = "SI";
            label4.Text = "Rate";
            label5.Text = "Time";
            label6.Text = "Principle";
        }
private void button5_Click(object sender, EventArgs e)
        {

            try
            {
                if (i == 1)
                {
                    si = (Convert.ToInt32(textBox1.Text) * Convert.ToInt32(textBox2.Text) * Convert.ToInt32(textBox3.Text)) / 100;
                    textBox4.Text = Convert.ToString(si);
                }
                if (i == 2)
                {
                    p = (Convert.ToInt32(textBox1.Text) * 100) / (Convert.ToInt32(textBox2.Text) * Convert.ToInt32(textBox3.Text));
                    textBox4.Text = Convert.ToString(p);
                }

I declared a variable "i" and assigned it with different values in different buttons and checked the value of i in the if function. It worked. Give your suggestions if any. Thank you.

i did this:

list = [1,2,3,4,5]
tuple = (list)

and to change, just do

list[0]=6

and u can change a tuple :D

here is it copied exactly from IDLE

>>> list=[1,2,3,4,5,6,7,8,9]

>>> tuple=(list)

>>> print(tuple)

[1, 2, 3, 4, 5, 6, 7, 8, 9]

>>> list[0]=6

>>> print(tuple)

[6, 2, 3, 4, 5, 6, 7, 8, 9]

You could use JavaScriptSerializer.

Here you can find a nice tutorial for calling a NuSOAP-based web-service from a .NET client application. But IMO, you should also consider the WSO2 Web Services Framework for PHP (WSO2 WSF/PHP) for servicing. See WSO2 Web Services Framework for PHP 2.0 Significantly Enhances Industry’s Only PHP Library for Creating Both SOAP and REST Services. There is also a webminar about it.

Now, in .NET world I also encourage the use of WCF, taking into account the interoperability issues. An interoperability example can be found here, but this example uses a PHP-client + WCF-service instead of the opposite. Feel free to implement the PHP-service & WFC-client.

There are some WCF's related open source projects on codeplex.com that I found very productive. These projects are very useful to design & implement Win Forms and Windows Presentation Foundation applications: Smart Client, Web Client and Mobile Client. They can be used in combination with WCF to wisely call any kind of Web services.

Generally speaking, the patterns & practices team summarize good practices & designs in various open source projects that dealing with the .NET platform, specially for the web. So I think it's a good starting point for any design decision related to .NET clients.

Reason for error:

1. The query from p in dc.BlogPosts where p.BlogPostID == ID select p returns a sequence.

2. Single() tries to retrieve an element from the sequence returned in step1.

3. As per the exception - The sequence returned in step1 contains no elements.

4. Single() tries to retrieve an element from the sequence returned in step1 which contains no elements.

5. Since Single() is not able to fetch a single element from the sequence returned in step1, it throws an error.

Fix:

Make sure the query (from p in dc.BlogPosts where p.BlogPostID == ID select p)

returns a sequence with at least one element.

Of course using private attributes, and getters and setters would be the recommended thing to do, but I tested the following, and it works... See the comment in the code

class Dad
{
    protected static String me = "dad";

    public void printMe()
    {
        System.out.println(me);
    }
}

class Son extends Dad
{
    protected static String me = "son";

    /* 
    Adding Method printMe() to this class, outputs son 
    even though Attribute me from class Dad can apparently not be overridden
    */

    public void printMe()
    {
        System.out.println(me);
    }
}

class Tester
{
    public static void main(String[] arg)
    {
        new Son().printMe();
    }
}

Sooo ... did I just redefine the rules of inheritance or did I put Oracle into a tricky situation ? To me, protected static String me is clearly overridden, as you can see when you execute this program. Also, it does not make any sense to me why attributes should not be overridable.

In man hostname there is even more easier way which automatically excluding loopback IP and showing only space separated list of all assigned to host ip addresses:

root@srv:~# hostname --all-ip-addresses
11.12.13.14 192.168.15.19 

root@srv:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
   inet 127.0.0.1/8 scope host lo
   inet6 ::1/128 scope host 
   valid_lft forever preferred_lft forever
2: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
  link/void 
  inet 11.12.13.14/32 scope global venet0:0
  inet 192.168.15.19/32 scope global venet0:1

With the new angular class Renderer2

constructor(private renderer:Renderer2) {}

  @ViewChild('one', { static: false }) d1: ElementRef;

  ngAfterViewInit() {
    const d2 = this.renderer.createElement('div');
    const text = this.renderer.createText('two');
    this.renderer.appendChild(d2, text);
    this.renderer.appendChild(this.d1.nativeElement, d2);
  }

You're interested in the collation. You could build something based on this snippet:

SELECT DATABASEPROPERTYEX('master', 'Collation');

Update
Based on your edit — If @test and @TEST can ever refer to two different variables, it's not SQL Server. If you see problems where the same variable is not equal to itself, check if that variable is NULL, because NULL = NULL returns `false.

you make the use of the HTML Helper and have

    @using(Html.BeginForm())
    {
        Username: <input type="text" name="username" /> <br />
        Password: <input type="text" name="password" /> <br />
        <input type="submit" value="Login">
        <input type="submit" value="Create Account"/>
    }

or use the Url helper

<form method="post" action="@Url.Action("MyAction", "MyController")" >

Html.BeginForm has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:

@using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
    < ... >
}

If you don't specify any arguments, the Html.BeginForm() will create a POST form that points to your current controller and current action. As an example, let's say you have a controller called Posts and an action called Delete

public ActionResult Delete(int id)
{
   var model = db.GetPostById(id);
   return View(model);
}

[HttpPost]
public ActionResult Delete(int id)
{
    var model = db.GetPostById(id);
    if(model != null) 
        db.DeletePost(id);

    return RedirectToView("Index");
}

and your html page would be something like:

<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>@Model.Title</strong> will be deleted.</p>

@using(Html.BeginForm())
{
    <input type="submit" class="btn btn-danger" value="Delete Post"/>
    <text>or</text>
    @Url.ActionLink("go to list", "Index")
}

You can run MSSQL and .NET Core on Linux, and hence inside Linux containers, nowadays.

See: https://hub.docker.com/r/microsoft/mssql-server-linux/

Also: https://hub.docker.com/r/microsoft/dotnet/

The direct question to your answer, is of course, unless there is a version compiled especially for Linux, no.

plt.axis('scaled')

works well for me.

Thanks to Novocaine88's answer to use a try catch loop I have successfully received an error message when I caused one.

    <?php
    $dbhost = "localhost";
    $dbname = "pdo";
    $dbusername = "root";
    $dbpassword = "845625";

    $link = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbusername, $dbpassword);
    $link->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    try {
        $statement = $link->prepare("INERT INTO testtable(name, lastname, age)
            VALUES(?,?,?)");

        $statement->execute(array("Bob","Desaunois",18));
    } catch(PDOException $e) {
        echo $e->getMessage();
    }
    ?>

In the following code instead of INSERT INTO it says INERT.

this is the error I got.

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'INERT INTO testtable(name, lastname, age) VALUES('Bob','Desaunoi' at line 1

When I "fix" the issue, it works as it should. Thanks alot everyone!

Just add the directory on the command line:

svn checkout svn://192.168.1.1/projectname/ target-directory/

On Windows and Linux, press Ctrl+K, then release the keys and press O (the letter O, not Zero).

On macOS, press command+K, then O (without holding command).

This will open the active file tab in a new window/instance.

Since you mentioned that you're working on a NFS system, do you have access to those semaphores and shared memory? I think you misunderstood what they are, they are an API code that enables processes to communicate with each other, semaphores are a solution for preventing race conditions and for threads to communicate with each other, in simple answer, they do not leave any residue on any filesystem.

Unless you are using an socket or a pipe? Do you have the necessary permissions to remove them, why are they on an NFS system?

Hope this helps, Best regards, Tom.

this worked perfectly for me:

for(a in array)console.log(array[a])

you can extract any array created in console for find/replace cleanup and posterior usage of this data extracted

If you remove or replace with a single character the invalid characters, you can have collisions:

<abc -> abc
>abc -> abc

Here is a simple method to avoid this:

public static string ReplaceInvalidFileNameChars(string s)
{
    char[] invalidFileNameChars = System.IO.Path.GetInvalidFileNameChars();
    foreach (char c in invalidFileNameChars)
        s = s.Replace(c.ToString(), "[" + Array.IndexOf(invalidFileNameChars, c) + "]");
    return s;
}

The result:

 <abc -> [1]abc
 >abc -> [2]abc

Mark gravell suggested this if you have .NET Core 3, System.Runtime.Intrinsics.X86.Popcnt.PopCount

public bool IsPowerOfTwo(uint i)
{
    return Popcnt.PopCount(i) == 1
}

Single instruction, faster than (x != 0) && ((x & (x - 1)) == 0) but less portable.

It looks like you were on the right track - get_FOO_display() is most certainly what you want:

In templates, you don't include () in the name of a method. Do the following:

{{ person.get_gender_display }}

As of AngularJS 1.1.3, you can now do exactly what you want using the new catch-all parameter.

https://github.com/angular/angular.js/commit/7eafbb98c64c0dc079d7d3ec589f1270b7f6fea5

From the commit:

This allows routeProvider to accept parameters that matches substrings even when they contain slashes if they are prefixed with an asterisk instead of a colon. For example, routes like edit/color/:color/largecode/*largecode will match with something like this http://appdomain.com/edit/color/brown/largecode/code/with/slashs.

I have tested it out myself (using 1.1.5) and it works great. Just keep in mind that each new URL will reload your controller, so to keep any kind of state, you may need to use a custom service.

The best way is to store native JavaScript Date objects, which map onto BSON native Date objects.

> db.test.insert({date: ISODate()})
> db.test.insert({date: new Date()})
> db.test.find()
{ "_id" : ObjectId("..."), "date" : ISODate("2014-02-10T10:50:42.389Z") }
{ "_id" : ObjectId("..."), "date" : ISODate("2014-02-10T10:50:57.240Z") }

The native type supports a whole range of useful methods out of the box, which you can use in your map-reduce jobs, for example.

If you need to, you can easily convert Date objects to and from Unix timestamps¹⁾, using the getTime() method and Date(milliseconds) constructor, respectively.

¹⁾ Strictly speaking, the Unix timestamp is measured in seconds. The JavaScript Date object measures in milliseconds since the Unix epoch.

Assuming that your current primary key constraint is called pk_history, you can replace the following lines:

ALTER TABLE history ADD PRIMARY KEY (id)

ALTER TABLE history
DROP CONSTRAINT userId
DROP CONSTRAINT name

with these:

ALTER TABLE history DROP CONSTRAINT pk_history

ALTER TABLE history ADD CONSTRAINT pk_history PRIMARY KEY (id)

If you don't know what the name of the PK is, you can find it with the following query:

SELECT * 
  FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
 WHERE TABLE_NAME = 'history'

Opera also has some support.

Generally however, it is too early to test out. You'll probably have to wait a year or 2 before any browser will have enough realistic support to test against.

EDIT Wikipedia has a good article on how much of HTML 5 various layout engines have implemented. It includes specific aspects of HTML 5.

• input = numpy_image
• np.unit8 -> converts to integers
• convert('RGB') -> converts to RGB

• Image.fromarray -> returns an image object

  from PIL import Image
  import numpy as np
  
  PIL_image = Image.fromarray(np.uint8(numpy_image)).convert('RGB')
  
  PIL_image = Image.fromarray(numpy_image.astype('uint8'), 'RGB')
  

Try this :

from __future__ import division

raw = [0.07, 0.14, 0.07]  

def norm(input_list):
    norm_list = list()

    if isinstance(input_list, list):
        sum_list = sum(input_list)

        for value in input_list:
            tmp = value  /sum_list
            norm_list.append(tmp) 

    return norm_list

print norm(raw)

This will do what you asked. But I will suggest to try Min-Max normalization.

min-max normalization :

def min_max_norm(dataset):
    if isinstance(dataset, list):
        norm_list = list()
        min_value = min(dataset)
        max_value = max(dataset)

        for value in dataset:
            tmp = (value - min_value) / (max_value - min_value)
            norm_list.append(tmp)

    return norm_list

Not totally sure what you mean by "automatically" - you can create a container object that holds both objects:

public class FileImageHolder { String fileName; String imageName; //TODO: insert stuff here }

And then put that in an array list and randomize that array list.

Otherwise, you would need to keep track of where each element moved in one list, and move it in the other one as well.

 $('mainCheckBox').click(function(){
    if($(this).prop('checked')){
        $('Id or Class of checkbox').prop('checked', true);
    }else{
        $('Id or Class of checkbox').prop('checked', false);
    }
});

I had hit the same problem and learnt the following-

Even though database has a default character set of utf-8, it's possible for database columns to have a different character set in MySQL. Modified dB and the problematic column to UTF-8:

mysql> ALTER DATABASE MyDB CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci'

mysql> ALTER TABLE database.table MODIFY COLUMN column_name VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL;

Now creating new tables with:

> CREATE TABLE My_Table_Name (
    twitter_id_str VARCHAR(255) NOT NULL UNIQUE,
    twitter_screen_name VARCHAR(512) CHARACTER SET utf8 COLLATE utf8_unicode_ci,
    .....
  ) CHARACTER SET utf8 COLLATE utf8_unicode_ci;

The following example show you how to define a function in jQuery. You will see a button “Click here”, when you click on it, we call our function “myFunction()”.

  $(document).ready(function(){
    $.myFunction = function(){ 
      alert('You have successfully defined the function!'); 
    }
    $(".btn").click(function(){
      $.myFunction();
    });
  });

You can see an example here: How to define a function in jQuery?

• Basically, a client-side stub is a procedure that looks to the client as if it were a callable server procedure.
• A server-side stub looks to the server as if it's a calling client.
• The client program thinks it is calling the server; in fact, it's calling the client stub.
• The server program thinks it's called by the client; in fact, it's called by the server stub.
• The stubs send messages to each other to make the RPC happen.

I had a similar issue, and following previous answers (thanks!), I was able to search and find how to handle correctly the ThreadPoolExecutor terminaison.

In my case, that just fix my progressive increase of similar blocked threads:

• I've used ExecutorService::awaitTermination(x, TimeUnit) and ExecutorService::shutdownNow() (if necessary) in my finally clause.

• For information, I've used the following commands to detect thread count & list locked threads:

  ps -u javaAppuser -L|wc -l

  jcmd `ps -C java -o pid=` Thread.print >> threadPrintDayA.log

  jcmd `ps -C java -o pid=` Thread.print >> threadPrintDayAPlusOne.log

  cat threadPrint*.log |grep "pool-"|wc -l

In my use case, I parameterized some fields in an HTML document, and once I load these fields I match and replace them using the str_replace method.

<?php echo str_replace(array("{{client_name}}", "{{client_testing}}"), array('client_company_name', 'test'), 'html_document'); ?>

All you need is:

    ActiveSheet.AutoFilter.ShowAllData

Why? Like the worksheet, AutoFilter also has a ShowAllData method, but it doesn't throw an error even when auto filter is enabled without an active filter.

• right-click the project and go to "Properties"
• C/C++ Build -> Settings -> Tool Settings -> GCC C++ Compiler -> Miscellaneous -> Other Flags. Put -lm at the end of other flags text box and OK.

Looking at the example HTML for radio buttons on the Twitter Bootstrap page (http://twitter.github.com/bootstrap/base-css.html#forms), you can see that each input has a unique ID attribute, i.e. optionsRadios1 and optionsRadios2.

The relevant HTML example snippet is included here for completeness:

<div class="controls">
  <label class="radio">
    <input type="radio" checked="" value="option1" id="optionsRadios1" name="optionsRadios">
    Option one is this and that—be sure to include why it's great
  </label>
  <label class="radio">
    <input type="radio" value="option2" id="optionsRadios2" name="optionsRadios">
    Option two can is something else and selecting it will deselect option one
  </label>
</div>

So you can use a jQuery click event, and then use the this reference to look at the id of the HTML element that was clicked.

$('.controls').find('input').bind('click',function(event){
  if($(this).attr('id')==='optionsRadios1'){
    alert($(this).attr('id'));
  } else {
    //... call some other function
  }
});

double d = 1.234567;
DecimalFormat df = new DecimalFormat("#.##");
System.out.print(df.format(d));

You can also add float:left; inside this class #User_Apps_Content .DLD_App a

Another method utilizing the dplyr package:

library(dplyr)
df <- mtcars %>%
        filter(mpg > 25)

Without the chain (%>%) operator:

library(dplyr)
df <- filter(mtcars, mpg > 25)

I would suggest to read up a bit on the syntax. See here.

if (dsnt<0.05) {
  wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE) 
} else if (dst<0.05) {
    wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else 
  t.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)

pls try this,

$('#select_id option[value="'+value+'"]').attr("disabled", true);

First, stop running containers before attempting to remove them

Remove running containers

docker rm $(docker stop -t=1 $(docker ps -q))

You could use kill instead of stop. In my case I prefer stop since I tend to rerun them vs. creating a new one every time so I try to shut them down nicely.

Note: Trying to stop a container will give you an error:

Error: Impossible to remove a running container, please stop it first

Remove all containers

docker rm $(docker ps -a -q)

The easiest way to do that is like below:

//Skip First Iteration

foreach ( int number in numbers.Skip(1))

//Skip any other like 5th iteration

foreach ( int number in numbers.Skip(5))

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut or via an instance e.g. shape.lolwut but be careful while setting it as it will set an instance level attribute not class attribute

class Shape(object):
    lolwut = 1

shape = Shape()

print Shape.lolwut,  # 1
print shape.lolwut,  # 1

# setting shape.lolwut would not change class attribute lolwut 
# but will create it in the instance
shape.lolwut = 2

print Shape.lolwut,  # 1
print shape.lolwut,  # 2

# to change class attribute access it via class
Shape.lolwut = 3

print Shape.lolwut,  # 3
print shape.lolwut   # 2 

output:

1 1 1 2 3 2

Somebody may expect output to be 1 1 2 2 3 3 but it would be incorrect

I would use it like this, its way shorter and it won't give any problems

        dynamic result = null;
        if (methodInfo != null)
        {
            ParameterInfo[] parameters = methodInfo.GetParameters();
            object classInstance = Activator.CreateInstance(type, null);
            result = methodInfo.Invoke(classInstance, parameters.Length == 0 ? null : parametersArray);
        }

np.save('data.npy', num_arr) # save
new_num_arr = np.load('data.npy') # load

Here is how to to that:

The header and footer are 30px height.

The footer is stuck to the bottom of the page.

HTML:

<div id="header">
</div>
<div id="content">
</div>
<div id="footer">
</div>

CSS:

#header {
    height: 30px;
}
#footer {
    height: 30px;
    position: absolute;
    bottom: 0;
}
body {
    height: 100%;
    margin-bottom: 30px;
}

This works for me.

order by cast(columnname as int) asc

Any way to do this without manually re-installing the packages in a new virtualenv to get their dependencies ? This would be error-prone and I'd like to automate the process of cleaning the virtualenv from no-longer-needed old dependencies.

That's what pip-tools package is for (from https://github.com/jazzband/pip-tools):

Installation

$ pip install --upgrade pip  # pip-tools needs pip==6.1 or higher (!)
$ pip install pip-tools

Example usage for pip-compile

Suppose you have a Flask project, and want to pin it for production. Write the following line to a file:

# requirements.in
Flask

Now, run pip-compile requirements.in:

$ pip-compile requirements.in
#
# This file is autogenerated by pip-compile
# Make changes in requirements.in, then run this to update:
#
#    pip-compile requirements.in
#
flask==0.10.1
itsdangerous==0.24        # via flask
jinja2==2.7.3             # via flask
markupsafe==0.23          # via jinja2
werkzeug==0.10.4          # via flask

And it will produce your requirements.txt, with all the Flask dependencies (and all underlying dependencies) pinned. Put this file under version control as well and periodically re-run pip-compile to update the packages.

Example usage for pip-sync

Now that you have a requirements.txt, you can use pip-sync to update your virtual env to reflect exactly what's in there. Note: this will install/upgrade/uninstall everything necessary to match the requirements.txt contents.

$ pip-sync

we all know generally that for sending the data according to the http standards we generally use POST request. But if you really want to use Get for sending the data in your scenario I would suggest you to use the query-string or query-parameters.

1.GET use of Query string as. {{url}}admin/recordings/some_id

here the some_id is mendatory parameter to send and can be used and req.params.some_id at server side.

2.GET use of query string as{{url}}admin/recordings?durationExact=34&isFavourite=true

here the durationExact ,isFavourite is optional strings to send and can be used and req.query.durationExact and req.query.isFavourite at server side.

3.GET Sending arrays {{url}}admin/recordings/sessions/?os["Windows","Linux","Macintosh"]

and you can access those array values at server side like this

let osValues = JSON.parse(req.query.os);
        if(osValues.length > 0)
        {
            for (let i=0; i<osValues.length; i++)
            {
                console.log(osValues[i])
                //do whatever you want to do here
            }
        }

It's important to write full class path in the xml. I got 'Error inflating class' when only subclass's name was written in.

Mine was putting the schema on the table Alias by mistake:

SELECT * FROM schema.CustomerOrders co
WHERE schema.co.ID = 1  -- oops!

I know it is kind an old post, but I've had the same problem and couldn't understand why your code didn't work. After a LOT of tests I've found out why.

It seems like fpm receives the full path from nginx and tries to find the files in the fpm container, so it must be the exactly the same as server.root in the nginx config, even if it doesn't exist in the nginx container.

To demonstrate:

docker-compose.yml

nginx:
    build: .
    ports:
        - "80:80"
    links:
        - fpm
fpm:
    image: php:fpm
    ports:
        - ":9000"

    # seems like fpm receives the full path from nginx
    # and tries to find the files in this dock, so it must
    # be the same as nginx.root
    volumes:
        - ./:/complex/path/to/files/

/etc/nginx/conf.d/default.conf

server {
    listen  80;

    # this path MUST be exactly as docker-compose.fpm.volumes,
    # even if it doesn't exist in this dock.
    root /complex/path/to/files;

    location / {
        try_files $uri /index.php$is_args$args;
    }

    location ~ ^/.+\.php(/|$) {
        fastcgi_pass fpm:9000;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

Dockerfile

FROM nginx:latest
COPY ./default.conf /etc/nginx/conf.d/

Just one more way to do this. Brettdj's answer made me think of this, but if you use this method you don't have to use a variant array, you can go directly to a string.

ColLtr = Cells(1, ColNum).Address(True, False)
ColLtr = Replace(ColLtr, "$1", "")

or can make it a little more compact with this

ColLtr = Replace(Cells(1, ColNum).Address(True, False), "$1", "")

Notice this does depend on you referencing row 1 in the cells object.

You can use the -f operator

$a = "{0:D}" -f (get-date)
$a = "{0:dddd}" -f (get-date)

The previous answers are now deprecated, you need to use ContextCompat.getColor to retrieve the color properly:

root.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.white));

Here is what worked for me.

I found that sometimes the controller was nil on the key window, as the keyWindow is some OS thing like an alert, etc.

 + (UIViewController*)topMostController
 {
     UIWindow *topWndow = [UIApplication sharedApplication].keyWindow;
     UIViewController *topController = topWndow.rootViewController;

     if (topController == nil)
     {
         // The windows in the array are ordered from back to front by window level; thus,
         // the last window in the array is on top of all other app windows.
         for (UIWindow *aWndow in [[UIApplication sharedApplication].windows reverseObjectEnumerator])
         {
             topController = aWndow.rootViewController;
             if (topController)
                 break;
         }
     }

     while (topController.presentedViewController) {
         topController = topController.presentedViewController;
     }

     return topController;
 }

I do something similar in one of my blog postings. A simple C++ example is shown.

The aim was to use the open source cvBlobsLib library for the detection of spot samples printed to microarray slides, but the images have to be converted from colour -> grayscale -> black + white as you mentioned, in order to achieve this.

There are some nice regexes for replacing HTML with BBCode here. For all you nay-sayers, note that he's not trying to fully parse HTML, just to sanitize it. He can probably afford to kill off tags that his simple "parser" can't understand.

Flutter is designed to use the latest Android version installed. So if you have an incomplete download of the latest Android, Flutter will try to use that.

Some things seem appeared to have changed in batch scripts on Windows 8, and the solution above by DGG now causes the Command Prompt to crash.

The following solution worked for me:

@echo off
set /a n=0
:repeat
set /a n+=1
echo 192.168.1.%n%
ping -n 1 -w 500 192.168.1.%n% | FIND /i "Reply">>ipaddresses.txt
if %n% lss 254 goto repeat
type ipaddresses.txt

Using a combination of SUBSTR, INSTR, and NVL (for strings without an underscore) will return what you want:

SELECT NVL(SUBSTR('ABC_blah', 0, INSTR('ABC_blah', '_')-1), 'ABC_blah') AS output
  FROM DUAL

Result:

output
------
ABC

Use:

SELECT NVL(SUBSTR(t.column, 0, INSTR(t.column, '_')-1), t.column) AS output
  FROM YOUR_TABLE t

Reference:

• SUBSTR
• INSTR

Addendum

If using Oracle10g+, you can use regex via REGEXP_SUBSTR.

Is there a prize for being lazy and using the transpose function of NumPy arrays? ;)

import numpy as np

a = np.array([(1,2,3), (4,5,6)])

b = a.transpose()

I had to change my values/styles.xml to

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

Before that change, it was without 'Base'.

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

PHP runs on the server and Javascript runs on the client, so you can't set a PHP variable to equal a Javascript variable without sending the value to the server. You can, however, set a Javascript variable to equal a PHP variable:

<script type="text/javascript">
  var foo = '<?php echo $foo ?>';
</script>

To send a Javascript value to PHP you'd need to use AJAX. With jQuery, it would look something like this (most basic example possible):

var variableToSend = 'foo';
$.post('file.php', {variable: variableToSend});

On your server, you would need to receive the variable sent in the post:

$variable = $_POST['variable'];

I did it with:

python3 -m pip install --upgrade tensorflow

I was hanging out on Google, then I found your question and it's very simple to parse JSON response into normal HTML. Just use this little JavaScript code:

<script>

var obj = JSON.parse('{ "name":"John", "age":30, "city":"New York"}');
document.getElementById("demo").innerHTML = obj.name + ", " + obj.age;

</script>

        }

        private void button1_Click(object sender, EventArgs e)
        {
            run_cmd();
        }

        private void run_cmd()
        {

            string fileName = @"C:\sample_script.py";

            Process p = new Process();
            p.StartInfo = new ProcessStartInfo(@"C:\Python27\python.exe", fileName)
            {
                RedirectStandardOutput = true,
                UseShellExecute = false,
                CreateNoWindow = true
            };
            p.Start();

            string output = p.StandardOutput.ReadToEnd();
            p.WaitForExit();

            Console.WriteLine(output);

            Console.ReadLine();

        }
    }
}

Python sample_script

print "Python C# Test"

You will see the 'Python C# Test' in the console of C#.

Add these methods to your Activity:

private MyService myServiceBinder;
public ServiceConnection myConnection = new ServiceConnection() {

    public void onServiceConnected(ComponentName className, IBinder binder) {
        myServiceBinder = ((MyService.MyBinder) binder).getService();
        Log.d("ServiceConnection","connected");
        showServiceData();
    }

    public void onServiceDisconnected(ComponentName className) {
        Log.d("ServiceConnection","disconnected");
        myService = null;
    }
};

public Handler myHandler = new Handler() {
    public void handleMessage(Message message) {
        Bundle data = message.getData();
    }
};

public void doBindService() {
    Intent intent = null;
    intent = new Intent(this, BTService.class);
    // Create a new Messenger for the communication back
    // From the Service to the Activity
    Messenger messenger = new Messenger(myHandler);
    intent.putExtra("MESSENGER", messenger);

    bindService(intent, myConnection, Context.BIND_AUTO_CREATE);
}

And you can bind to service by ovverriding onResume(), and onPause() at your Activity class.

@Override
protected void onResume() {

    Log.d("activity", "onResume");
    if (myService == null) {
        doBindService();
    }
    super.onResume();
}

@Override
protected void onPause() {
    //FIXME put back

    Log.d("activity", "onPause");
    if (myService != null) {
        unbindService(myConnection);
        myService = null;
    }
    super.onPause();
}

Note, that when binding to a service only the onCreate() method is called in the service class. In your Service class you need to define the myBinder method:

private final IBinder mBinder = new MyBinder();
private Messenger outMessenger;

@Override
public IBinder onBind(Intent arg0) {
    Bundle extras = arg0.getExtras();
    Log.d("service","onBind");
    // Get messager from the Activity
    if (extras != null) {
        Log.d("service","onBind with extra");
        outMessenger = (Messenger) extras.get("MESSENGER");
    }
    return mBinder;
}

public class MyBinder extends Binder {
    MyService getService() {
        return MyService.this;
    }
}

After you defined these methods you can reach the methods of your service at your Activity:

private void showServiceData() {  
    myServiceBinder.myMethod();
}

and finally you can start your service when some event occurs like _BOOT_COMPLETED_

public class MyReciever  extends BroadcastReceiver {
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals("android.intent.action.BOOT_COMPLETED")) {
            Intent service = new Intent(context, myService.class);
            context.startService(service);
        }
    }
}

note that when starting a service the onCreate() and onStartCommand() is called in service class and you can stop your service when another event occurs by stopService() note that your event listener should be registerd in your Android manifest file:

<receiver android:name="MyReciever" android:enabled="true" android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
</receiver>

you can do it with pd.date_range() and Timestamp. Let's say you have read a csv file with a date column using parse_dates option:

df = pd.read_csv('my_file.csv', parse_dates=['my_date_col'])

Then you can define a date range index :

rge = pd.date_range(end='15/6/2020', periods=2)

and then filter your values by date thanks to a map:

df.loc[df['my_date_col'].map(lambda row: row.date() in rge)]

In most cases the slug should not change, so you really only want to calculate it on first save:

class Test(models.Model):
    q = models.CharField(max_length=30)
    s = models.SlugField(editable=False) # hide from admin

    def save(self):
        if not self.id:
            self.s = slugify(self.q)

        super(Test, self).save()

I can't find a single reference that state that it's possible without involving the serverside.

MSDN on:

• navigator.browserLanguage
• navigator.systemLanguage
• navigator.userLanguage

From browserLanguage:

In Microsoft Internet Explorer 4.0 and earlier, the browserLanguage property reflects the language of the installed browser's user interface. For example, if you install a Japanese version of Windows Internet Explorer on an English operating system, browserLanguage would be ja.

In Internet Explorer 5 and later, however, the browserLanguage property reflects the language of the operating system regardless of the installed language version of Internet Explorer. However, if Microsoft Windows 2000 MultiLanguage version is installed, the browserLanguage property indicates the language set in the operating system's current menus and dialogs, as found in the Regional Options of the Control Panel. For example, if you install a Japanese version of Internet Explorer 5 on an English (United Kingdom) operating system, browserLanguage would be en-gb. If you install Windows 2000 MultiLanguage version and set the language of the menus and dialogs to French, browserLanguage would be fr, even though you have a Japanese version of Internet Explorer.

Note This property does not indicate the language or languages set by the user in Language Preferences, located in the Internet Options dialog box.

Furthermore, it looks like browserLanguage is deprecated cause IE8 doesn't list it

Another way that skips even numbers after 2 is handled:

def prime_factors(n):
   factors = []
   d    = 2
   step = 1
   while d*d <= n:
      while n>1:
         while n%d == 0:
            factors.append(d)
            n = n/d
        d += step
        step = 2

  return factors

If you are only concerned with 8 bit characters (which all other answers except Milan Babuškov assume as well) you can get the fastest speed by generating a look-up table at compile time using metaprogramming. On ideone.com this runs 7x faster than the library function and 3x faster than a hand written version (http://ideone.com/sb1Rup). It is also customizeable through traits with no slow down.

template<int ...Is>
struct IntVector{
using Type = IntVector<Is...>;
};

template<typename T_Vector, int I_New>
struct PushFront;
template<int ...Is, int I_New>
struct PushFront<IntVector<Is...>,I_New> : IntVector<I_New,Is...>{};

template<int I_Size, typename T_Vector = IntVector<>>
struct Iota : Iota< I_Size-1, typename PushFront<T_Vector,I_Size-1>::Type> {};
template<typename T_Vector>
struct Iota<0,T_Vector> : T_Vector{};

template<char C_In>
struct ToUpperTraits {
    enum { value = (C_In >= 'a' && C_In <='z') ? C_In - ('a'-'A'):C_In };
};

template<typename T>
struct TableToUpper;
template<int ...Is>
struct TableToUpper<IntVector<Is...>>{
    static char at(const char in){
        static const char table[] = {ToUpperTraits<Is>::value...};
        return table[in];
    }
};

int tableToUpper(const char c){
    using Table = TableToUpper<typename Iota<256>::Type>;
    return Table::at(c);
}

with use case:

std::transform(in.begin(),in.end(),out.begin(),tableToUpper);

For an in depth (many page) decription of how it works allow me to shamelessly plug my blog: http://metaporky.blogspot.de/2014/07/part-4-generating-look-up-tables-at.html

Works that way as well, a bit more tidy. getQuery() just returns the underlying builder, which already contains the table reference.

$browser_total_raw = DB::raw('count(*) as total');
$user_info = Usermeta::getQuery()
                     ->select('browser', $browser_total_raw)
                     ->groupBy('browser')
                     ->pluck('total','browser');

I know I am 3 years late on this thread, however still providing my 2 cents for similar cases in future.

I recently faced the same issue/error in my cluster. The JOB would always get to some 80%+ reduction and fail with the same error, with nothing to go on in the execution logs either. Upon multiple iterations and research I found that among the plethora of files getting loaded some were non-compliant with the structure provided for the base table(table being used to insert data into partitioned table).

Point to be noted here is whenever I executed a select query for a particular value in the partitioning column or created a static partition it worked fine as in that case error records were being skipped.

TL;DR: Check the incoming data/files for inconsistency in the structuring as HIVE follows Schema-On-Read philosophy.

Pure javascript solution with scrollIntoView() function:

document.getElementById('title1').scrollIntoView({block: 'start', behavior: 'smooth'});

<h2 id="title1">Some title</h2>

P.S. 'smooth' parameter now works from Chrome 61 as julien_c mentioned in the comments.

The following is the sort of syntax I use for major upgrades:

<Product Id="*" UpgradeCode="PUT-GUID-HERE" Version="$(var.ProductVersion)">
 <Upgrade Id="PUT-GUID-HERE">
    <UpgradeVersion OnlyDetect="yes" Minimum="$(var.ProductVersion)" Property="NEWERVERSIONDETECTED" IncludeMinimum="no" />
    <UpgradeVersion OnlyDetect="no" Maximum="$(var.ProductVersion)" Property="OLDERVERSIONBEINGUPGRADED" IncludeMaximum="no" />
</Upgrade>

<InstallExecuteSequence>
    <RemoveExistingProducts After="InstallInitialize" />
</InstallExecuteSequence>

As @Brian Gillespie noted there are other places to schedule the RemoveExistingProducts depending on desired optimizations. Note the PUT-GUID-HERE must be identical.

Since I cant comment yet im gonna post as an answer the link.. I have found a simple, well organized tutorial on recyclerview http://www.androiddeft.com/2017/10/01/recyclerview-android/

Apart from that when you are going to add a recycler view into you activity what you want to do is as below and how you should do this has been described on the link

• add RecyclerView component into your layout file
• make a class which you are going to display as list rows
• make a layout file which is the layout of a row of you list
• now we need a custom adapter so create a custom adapter by extending from the parent class RecyclerView.Adapter
• add recyclerview into your mainActivity oncreate
• adding separators
• adding Touch listeners

Assuming your php install has the CURL extension, it is probably the easiest way (and most complete, if you wish).

Sample snippet:

//set POST variables
$url = 'http://domain.com/get-post.php';
$fields = array(
                      'lname'=>urlencode($last_name),
                      'fname'=>urlencode($first_name),
                      'email'=>urlencode($email)
               );

//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string,'&');

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);

I would think of one more case when pessimistic locking would be a better choice.

For optimistic locking every participant in data modification must agree in using this kind of locking. But if someone modifies the data without taking care about the version column, this will spoil the whole idea of the optimistic locking.

get current activity from parent, then using this code

getActivity().getSupportFragmentManager()

For folks that have programmed in nodeJs before, particularly using expressJS. I think of .ashx as a middleware that calls the next function. While .aspx will be the controller that actually responds to the request either around res.redirect, res.send or whatever.

I had the same problem with Spring Boot, Spring Cloud (microservices) and a self-signed SSL certificate. Keystore worked out of the box from application properties, and Truststore didn't.

I ended up keeping both keystore and trustore configuration in application.properties, and adding a separate configuration bean for configuring truststore properties with the System.

@Configuration
public class SSLConfig {
    @Autowired
    private Environment env;

    @PostConstruct
    private void configureSSL() {
      //set to TLSv1.1 or TLSv1.2
      System.setProperty("https.protocols", "TLSv1.1");

      //load the 'javax.net.ssl.trustStore' and
      //'javax.net.ssl.trustStorePassword' from application.properties
      System.setProperty("javax.net.ssl.trustStore", env.getProperty("server.ssl.trust-store")); 
      System.setProperty("javax.net.ssl.trustStorePassword",env.getProperty("server.ssl.trust-store-password"));
    }
}

DAO and Repository pattern are ways of implementing Data Access Layer (DAL). So, let's start with DAL, first.

Object-oriented applications that access a database, must have some logic to handle database access. In order to keep the code clean and modular, it is recommended that database access logic should be isolated into a separate module. In layered architecture, this module is DAL.

So far, we haven't talked about any particular implementation: only a general principle that putting database access logic in a separate module.

Now, how we can implement this principle? Well, one know way of implementing this, in particular with frameworks like Hibernate, is the DAO pattern.

DAO pattern is a way of generating DAL, where typically, each domain entity has its own DAO. For example, User and UserDao, Appointment and AppointmentDao, etc. An example of DAO with Hibernate: http://gochev.blogspot.ca/2009/08/hibernate-generic-dao.html.

Then what is Repository pattern? Like DAO, Repository pattern is also a way achieving DAL. The main point in Repository pattern is that, from the client/user perspective, it should look or behave as a collection. What is meant by behaving like a collection is not that it has to be instantiated like Collection collection = new SomeCollection(). Instead, it means that it should support operations such as add, remove, contains, etc. This is the essence of Repository pattern.

In practice, for example in the case of using Hibernate, Repository pattern is realized with DAO. That is an instance of DAL can be both at the same an instance of DAO pattern and Repository pattern.

Repository pattern is not necessarily something that one builds on top of DAO (as some may suggest). If DAOs are designed with an interface that supports the above-mentioned operations, then it is an instance of Repository pattern. Think about it, If DAOs already provide a collection-like set of operations, then what is the need for an extra layer on top of it?

I think it's a better way to bind on the service itself instead of the attributes on it.

Here's why:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.7/angular.min.js"></script>
<body ng-app="BindToService">

  <div ng-controller="BindToServiceCtrl as ctrl">
    ArrService.arrOne: <span ng-repeat="v in ArrService.arrOne">{{v}}</span>
    <br />
    ArrService.arrTwo: <span ng-repeat="v in ArrService.arrTwo">{{v}}</span>
    <br />
    <br />
    <!-- This is empty since $scope.arrOne never changes -->
    arrOne: <span ng-repeat="v in arrOne">{{v}}</span>
    <br />
    <!-- This is not empty since $scope.arrTwo === ArrService.arrTwo -->
    <!-- Both of them point the memory space modified by the `push` function below -->
    arrTwo: <span ng-repeat="v in arrTwo">{{v}}</span>
  </div>

  <script type="text/javascript">
    var app = angular.module("BindToService", []);

    app.controller("BindToServiceCtrl", function ($scope, ArrService) {
      $scope.ArrService = ArrService;
      $scope.arrOne = ArrService.arrOne;
      $scope.arrTwo = ArrService.arrTwo;
    });

    app.service("ArrService", function ($interval) {
      var that = this,
          i = 0;
      this.arrOne = [];
      that.arrTwo = [];

      $interval(function () {
        // This will change arrOne (the pointer).
        // However, $scope.arrOne is still same as the original arrOne.
        that.arrOne = that.arrOne.concat([i]);

        // This line changes the memory block pointed by arrTwo.
        // And arrTwo (the pointer) itself never changes.
        that.arrTwo.push(i);
        i += 1;
      }, 1000);

    });
  </script>
</body> 

You can play it on this plunker.

I typically use triggers to handle timestamps but I think this may work.

$data = array(
    'name' => $name,
    'email' => $email
);

$this->db->set('time', 'NOW()', FALSE);
$this->db->insert('mytable', $data);

You can Use below code to call the web service and get response .Make sure that your Web Service return the response in Data Table Format..This code help you if you using data from SQL Server database .If you you using MYSQL you need to change one thing just replace word NewDataSet from sentence obj2=(SoapObject) obj1.getProperty("NewDataSet"); by DocumentElement

private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://localhost/Web_Service.asmx?"; // you can use   IP address instead of localhost
private static final String METHOD_NAME = "Function_Name";
private static final String SOAP_ACTION = NAMESPACE + METHOD_NAME;

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("parm_name", prm_value); // Parameter for Method
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

try {
    androidHttpTransport.call(SOAP_ACTION, envelope); //call the eb service Method
} catch (Exception e) {
    e.printStackTrace();
} //Next task is to get Response and format that response

SoapObject obj, obj1, obj2, obj3;
obj = (SoapObject) envelope.getResponse();
obj1 = (SoapObject) obj.getProperty("diffgram");
obj2 = (SoapObject) obj1.getProperty("NewDataSet");

for (int i = 0; i < obj2.getPropertyCount(); i++) //the method getPropertyCount() return the number of rows
{
    obj3 = (SoapObject) obj2.getProperty(i);
    obj3.getProperty(0).toString(); //value of column 1
    obj3.getProperty(1).toString(); //value of column 2
    //like that you will get value from each column
}

If you have any problem regarding this you can write me..

From Stack Overflow question What is the Python 3 equivalent of "python -m SimpleHTTPServer":

The following works for me:

python -m http.server [<portNo>]

Because I am using Python 3 the module SimpleHTTPServer has been replaced by http.server, at least in Windows.

I had an idea about using a RAM drive. It turned out that for my projects it doesn't make that much of a difference after all. But then they are pretty small still. Try it! I'd be interested in hearing how much it helped.

Issue the following command,the way to run specified logrotate:

logrotate -vf /etc/logrotate.d/custom

Options:

-v :show the process

-f :forcing run

custom :user-defined log setting

eg: mongodb-log

# mongodb-log rotate

/data/var/log/mongodb/mongod.log {
    daily
    dateext
    rotate 30
    copytruncate
    missingok
}

Make sure your project defines a module and you have given a name to the module. Then rebuild, and Xcode will create the -Swift.h header file and you will be able to import.

You can set module definition and module name in your project settings.

This query works for me:

SELECT DISTINCT 
    local_tcp_port 
FROM sys.dm_exec_connections 
WHERE local_tcp_port IS NOT NULL 

In case if you want to change multiple columns of a specific type to another without specifying individual column names

/* Get names of all columns that you want to change type. 
In this example I want to change all columns of type Array to String*/
    val arrColsNames = originalDataFrame.schema.fields.filter(f => f.dataType.isInstanceOf[ArrayType]).map(_.name)

//iterate columns you want to change type and cast to the required type
val updatedDataFrame = arrColsNames.foldLeft(originalDataFrame){(tempDF, colName) => tempDF.withColumn(colName, tempDF.col(colName).cast(DataTypes.StringType))}

//display

updatedDataFrame.show(truncate = false)

I created a class structure for collections in general that would meet this requirement. and it looks like this:

class Collection {

    constructor() {
        this.collection = [];
        this.index = 0;
    }

    log() {
        return console.log(this.collection);
    }

    push(value) {
        return this.collection.push(value);
    }

    pushAll(...values) {
        return this.collection.push(...values);
    }

    pop() {
        return this.collection.pop();
    }

    shift() {
        return this.collection.shift();
    }

    unshift(value) {
        return this.collection.unshift(value);
    }

    unshiftAll(...values) {
        return this.collection.unshift(...values);
    }

    remove(index) {
        return this.collection.splice(index, 1);
    }

    add(index, value) {
        return this.collection.splice(index, 0, value);
    }

    replace(index, value) {
        return this.collection.splice(index, 1, value);
    }

    clear() {
        this.collection.length = 0;
    }

    isEmpty() {
        return this.collection.length === 0;
    }

    viewFirst() {
        return this.collection[0];
    }

    viewLast() {
        return this.collection[this.collection.length - 1];
    }

    current(){
        if((this.index <= this.collection.length - 1) && (this.index >= 0)){
            return this.collection[this.index];
        }
        else{
            return `Object index exceeds collection range.`;
        }
    }

    next() {
        this.index++;
        this.index > this.collection.length - 1 ? this.index = 0 : this.index;
        return this.collection[this.index];
    }

    previous(){
        this.index--;
        this.index < 0 ? (this.index = this.collection.length-1) : this.index;
        return this.collection[this.index];
    }
}

...and essentially what you would do is have a collection of arrays of whatever length for your pages pushed into the class object, and then use the next() and previous() functions to display whatever 'page' (index) you wanted to display. Would essentially look like this:

let books = new Collection();
let firstPage - [['dummyData'], ['dummyData'], ['dummyData'], ['dummyData'], ['dummyData'],];
let secondPage - [['dumberData'], ['dumberData'], ['dumberData'], ['dumberData'], ['dumberData'],];
books.pushAll(firstPage, secondPage); // loads each array individually
books.current() // display firstPage
books.next() // display secondPage

If you're worried about performance, check out the Boost::lexical_cast library.

Use DATE(NOW()) to compare dates

DATE(NOW()) will give you the date part of current date and DATE(duedate) will give you the date part of the due date. then you can easily compare the dates

So you can compare it like

DATE(NOW()) = DATE(duedate)

OR

DATE(duedate) = CURDATE() 

See here

It is important to note that 'undefined' is a perfectly valid value for a variable to hold. If you want to check if the variable exists at all,

if (window.variableName)

is a more complete check, since it is verifying that the variable has actually been defined. However, this is only useful if the variable is guaranteed to be an object! In addition, as others have pointed out, this could also return false if the value of variableName is false, 0, '', or null.

That said, that is usually not enough for our everyday purposes, since we often don't want to have an undefined value. As such, you should first check to see that the variable is defined, and then assert that it is not undefined using the typeof operator which, as Adam has pointed out, will not return undefined unless the variable truly is undefined.

if ( variableName  && typeof variableName !== 'undefined' )

This is very simple you need to keep different names of every radio input group.

      <input type="radio" name="price">Thousand<br>_x000D_
      <input type="radio" name="price">Lakh<br>_x000D_
      <input type="radio" name="price">Crore_x000D_
      _x000D_
      </br><hr>_x000D_
_x000D_
      <input type="radio" name="gender">Male<br>_x000D_
      <input type="radio" name="gender">Female<br>_x000D_
      <input type="radio" name="gender">Other

Another option is to do it via CSS ...

E.g. 1

<span style="font-weight: bold;">Hello stackoverflow!</span>

E.g. 2

<style type="text/css">
    #text

I don't believe this is possible. The dialog box that gets displayed allows the user to select a printer to print to. So, let's say it would be possible for your application to just click and print, and a user clicks your print button, but has two printers connected to the computer. Or, more likely, that user is working in an office building with 25 printers. Without that dialog box, how would the computer know to which printer to print?

almost a decade passed but the issue still valid with Asp.Net Core 2.2 as well.

I managed it by adding data-val-number to the input field the use localization on the message:

<input asp-for="Age" data-val-number="@_localize["Please enter a valid number."]"/>

You have to set a reference to the workbook you're opening. Then you can do anything you want with that workbook by using its reference.

Dim wkb As Workbook
Set wkb = Workbooks.Open("Tire.xls") ' open workbook and set reference!

wkb.Sheets("Sheet1").Activate
wkb.Sheets("Sheet1").Cells(2, 1).Value = 123

Could even set a reference to the sheet, which will make life easier later:

Dim wkb As Workbook
Dim sht As Worksheet

Set wkb = Workbooks.Open("Tire.xls")
Set sht = wkb.Sheets("Sheet2")

sht.Activate
sht.Cells(2, 1) = 123

Others have pointed out that .Activate may be superfluous in your case. You don't strictly need to activate a sheet before editing its cells. But, if that's what you want to do, it does no harm to activate -- except for a small hit to performance which should not be noticeable as long as you do it only once or a few times. However, if you activate many times e.g. in a loop, it will slow things down significantly, so activate should be avoided.

I see you already have a answer but here is another answer, maybe even faster A simple class to pass in a List of objects and retrieve either a csv or excel or password protected zip csv or excel. https://github.com/ernst223/spread-sheet-exporter

SpreadSheetExporter spreadSheetExporter = new SpreadSheetExporter(List<Object>, "Filename");
File fileCSV = spreadSheetExporter.getCSV();

Use the flex-grow property to make a flex item consume free space on the main axis.

This property will expand the item as much as possible, adjusting the length to dynamic environments, such as screen re-sizing or the addition / removal of other items.

A common example is flex-grow: 1 or, using the shorthand property, flex: 1.

Hence, instead of width: 96% on your div, use flex: 1.

You wrote:

So at the moment, it's set to 96% which looks OK until you really squash the screen - then the right hand div gets a bit starved of the space it needs.

The squashing of the fixed-width div is related to another flex property: flex-shrink

By default, flex items are set to flex-shrink: 1 which enables them to shrink in order to prevent overflow of the container.

To disable this feature use flex-shrink: 0.

For more details see The flex-shrink factor section in the answer here:

• What are the differences between flex-basis and width?

A couple of issues

• You're not limiting it to files, so when it finds a matching directory it will list every file within it.
• You can't use > in -exec without something like bash -c '... > ...'. Though the > will overwrite the file, so you want to redirect the entire find anyway rather than each -exec.
• +30 is older than 30 days, -30 would be modified in last 30 days.
• -exec really isn't needed, you could list everything with various -printf options.

Something like below should work

find . -type f -mtime -30 -exec ls -l {} \; > last30days.txt

Example with -printf

find . -type f -mtime -30 -printf "%M %u %g %TR %TD %p\n" > last30days.txt

This will list files in format "permissions owner group time date filename". -printf is generally preferable to -exec in cases where you don't have to do anything complicated. This is because it will run faster as a result of not having to execute subshells for each -exec. Depending on the version of find, you may also be able to use -ls, which has a similar format to above.

raw_data['Mycol'] =  pd.to_datetime(raw_data['Mycol'], format='%d%b%Y:%H:%M:%S.%f')

works, however it results in a Python warning of A value is trying to be set on a copy of a slice from a DataFrame. Try using .loc[row_indexer,col_indexer] = value instead

I would guess this is due to some chaining indexing.

Best way to solve this until a fix is available (if a fix comes) is to force IE compatibility mode on the user.

Use <META http-equiv="X-UA-Compatible" content="IE=9"> ideally in the masterpage so all pages in your site get the workaround.

This would be better approach as I have implemented :)

@model ObjectUser
@using System.Web.Script.Serialization
@{ 
    var javaScriptSearilizer = new JavaScriptSerializer();
    var searializedObject = javaScriptSearilizer.Serialize(Model);
 }

<script>
    var searializedObject = @Html.Raw(searializedObject )
    console.log(searializedObject);
    alert(searializedObject);
</script>

Hope this will help you to prevent you from iterating model ( happy coding )

This might help

def digit_sum(n):
    num_str = str(n)
    sum = 0
    for i in range(0, len(num_str)):
        sum += int(num_str[i])
    return sum

One way of doing this is to do add junit.jar to your $CLASSPATH as an external dependency.

So to do that, go to project structure, and then add JUnit as one of the libraries as shown in the gif.

In the 'Choose Modules' prompt choose only the modules that you'd need JUnit for.

Or in your SQL query wrap that field with IsNull or Coalesce (SQL Server).

Either way works, I like to put that logic in the query so the report has to do less.

It is not possible to directly make a 3d surface using your data. I would recommend you to build an interpolation model using some tools like pykridge. The process will include three steps:

1. Train an interpolation model using pykridge
2. Build a grid from X and Y using meshgrid
3. Interpolate values for Z

Having created your grid and the corresponding Z values, now you're ready to go with plot_surface. Note that depending on the size of your data, the meshgrid function can run for a while. The workaround is to create evenly spaced samples using np.linspace for X and Y axes, then apply interpolation to infer the necessary Z values. If so, the interpolated values might different from the original Z because X and Y have changed.

If you want to display 24 hours format use:

SELECT FORMAT(GETDATE(),'HH:mm')

and to display 12 hours format use:

SELECT FORMAT(GETDATE(),'hh:mm')

If you want a list of columns of a certain type, you can use groupby:

>>> df = pd.DataFrame([[1, 2.3456, 'c', 'd', 78]], columns=list("ABCDE"))
>>> df
   A       B  C  D   E
0  1  2.3456  c  d  78

[1 rows x 5 columns]
>>> df.dtypes
A      int64
B    float64
C     object
D     object
E      int64
dtype: object
>>> g = df.columns.to_series().groupby(df.dtypes).groups
>>> g
{dtype('int64'): ['A', 'E'], dtype('float64'): ['B'], dtype('O'): ['C', 'D']}
>>> {k.name: v for k, v in g.items()}
{'object': ['C', 'D'], 'int64': ['A', 'E'], 'float64': ['B']}

You can use button classes btn-link and btn-xs with type submit, which will make a small invisible button with an icon inside of it. Example:

<button class="btn btn-link btn-xs" type="submit" name="action" value="delete">
    <i class="fa fa-times text-danger"></i>
</button>

If you get this sort of thing appearing suddenly, it usually means the project is missing some frameworks it needs. Libraries and dependent projects can require frameworks, so if you've added one recently then that can cause this error.

To add frameworks, right click on the project name in the project view, select Add, then select Existing frameworks... from the list. Then find the framework with the symbols you're missing.

As to how you find which frameworks you need, I've found using google the easiest, though you could probably use the Xcode help search too. Search for one of the symbols, doing your best to work out the unmangled name (e.g., SCNetworkReachabilityGetFlags), and then the first documentation link you find at developer.apple.com is often the right one. You usually don't have to hunt very far. In this case, that's this page:

https://developer.apple.com/documentation/systemconfiguration/scnetworkreachability-g7d

Then at the top of the page, it tells you which framework to use, SystemConfiguration in this case. So add that to the project, and compile again.

Then just keep doing this until it works...

Edit: I've never used the simulator, but this is what you do on the device - I assume it's the same...

Both the size attribute in HTML and the width property in CSS will set the width of an <input>. If you want to set the width to something closer to the width of each character use the **ch** unit as in:

input {
    width: 10ch;
}
