You will need to put the try/except inside the most innerloop where the error may occur, i.e.

for i in something:
    for j in somethingelse:
        for k in whatever:
            try:
                something_complex(i, j, k)
            except Exception, e:
                print e
        try:
            something_less_complex(i, j)
        except Exception, e:
            print e

... and so on

In other words, you will need to wrap statements that may fail in try/except as specific as possible, in the most inner-loop as possible.

import sys, os

try:
    raise NotImplementedError("No error")
except Exception as e:
    exc_type, exc_obj, exc_tb = sys.exc_info()
    fname = os.path.split(exc_tb.tb_frame.f_code.co_filename)[1]
    print(exc_type, fname, exc_tb.tb_lineno)

It's worth looking at Pydb, "an expanded version of the Python debugger loosely based on the gdb command set". It includes signal managers which can take care of starting the debugger when a specified signal is sent.

A 2006 Summer of Code project looked at adding remote-debugging features to pydb in a module called mpdb.

What about

import sys
....
....
....
sys.exit("I am getting the heck out of here!")

No traceback and somehow more explicit.

import inspect

def foo():
   print(inspect.stack()[0][3])
   print(inspect.stack()[1][3]) #will give the caller of foos name, if something called foo

Add PresentationCore.dll to your references. This dll url in my pc - C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\PresentationCore.dll

I had this problem with a Silverlight 5 upgraded from a previous version.

Even re-adding the service reference still gave me an empty Reference.cs

I ended up having to create a brand new project and re-creating the service reference. This is something to try if you've spent more than about half an hour on this. Even if you're determined to fix the original project you may want to try this just to see what happens and then work backwards to try to fix the problem.

I never did figure out exactly what the problem was - but possibly something in the .csproj file wasn't upgraded or some setting went wrong.

I hit this issue. This architecture (from Lain's answer) worked for me. Here is the solution in Python.

  • alternative
    • text
    • related
      • html

Thanks @davy-landmann for https://stackoverflow.com/a/638064/417153. That's what I was looking for! Same effect with LESS code:

For Django3.0+, use models.TextChoices (see docs-v3.0 for enumeration types)

from django.db import models

class MyModel(models.Model):
    class Month(models.TextChoices):
        JAN = '1', "JANUARY"
        FEB = '2', "FEBRUARY"
        MAR = '3', "MAR"
        # (...)

    month = models.CharField(
        max_length=2,
        choices=Month.choices,
        default=Month.JAN
    )

Usage::

>>> obj = MyModel.objects.create(month='1')
>>> assert obj.month == obj.Month.JAN
>>> assert MyModel.Month(obj.month).label == 'JANUARY'
>>> assert MyModel.objects.filter(month=MyModel.Month.JAN).count() >= 1

>>> obj2 = MyModel(month=MyModel.Month.FEB)
>>> assert obj2.get_month_display() == obj2.Month(obj2.month).label

I have used winston logger earlier.

Nowadays I am using below simpler code from experience:

1. Set the environment variable from cmd/ command line (on Windows):

   cmd
   setx LOG_LEVEL info
   

Or, you could have a variable in your code if you like, but above is better.

2. Restart cmd/ command line, or, IDE/ editor like Netbeans

3. Have below like code:

   console.debug = console.log;   // define debug function
   console.silly = console.log;   // define silly function
   
   switch (process.env.LOG_LEVEL) {
       case 'debug':
       case 'silly':
           // print everything
           break;
   
       case 'dir':
       case 'log':
           console.debug = function () {};
           console.silly = function () {};
           break;
   
       case 'info':
           console.debug = function () {};
           console.silly = function () {};
           console.dir = function () {};
           console.log = function () {};
           break;
   
       case 'trace':   // similar to error, both may print stack trace/ frames
       case 'warn':    // since warn() function is an alias for error()
       case 'error':
           console.debug = function () {};
           console.silly = function () {};
           console.dir = function () {};
           console.log = function () {};
           console.info = function () {};
           break;
   }
   

4. Now use all console.* as below:

   console.error(' this is a error message '); // will print
   console.warn(' this is a warn message '); // will print
   console.trace(' this is a trace message '); // will print
   console.info(' this is a info message '); // will print, LOG_LEVEL is set to this
   
   console.log(' this is a log message '); // will NOT print
   console.dir(' this is a dir message '); // will NOT print
   console.silly(' this is a silly message '); // will NOT print
   console.debug(' this is a debug message '); // will NOT print
   

Now, based on your LOG_LEVEL settings made in the point 1 (like, setx LOG_LEVEL log and restart command line), some of the above will print, others won't print

Hope that helped.

Java 8...

String joined = String.join("+", list);

If you removed the make all line from your "fresh" target:

fresh :
    rm -f *.o $(EXEC)
    clear

You could simply run the command make fresh all, which will execute as make fresh; make all.

Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.

Have a look at this excellent brief post on how to do this properly.

Essentially: catch the InterruptedException. Remember that you must add this catch-block. The post explains this a bit further.

By default reference types have reference equality (i.e. two instances are only equal if they are the same object).

You need to override Object.Equals (and Object.GetHashCode to match) to implement your own equality. (And it is then good practice to implement an equality, ==, operator.)

Interesting question - I don't think there's any Oracle function that does this (almost like a "which" command in Unix), but you can get the resolution order for the name by:

select * from 
(
 select  object_name objname, object_type, 'my object' details, 1 resolveOrder 
  from user_objects
  where object_type not like 'SYNONYM'
 union all
 select synonym_name obj , 'my synonym', table_owner||'.'||table_name, 2 resolveOrder
  from user_synonyms
 union all
 select  synonym_name obj , 'public synonym', table_owner||'.'||table_name, 3 resolveOrder
  from all_synonyms where owner = 'PUBLIC'
)
where objname like upper('&objOfInterest')

I would go for aspect-ratio, it offers way more possibilities.

/* Exact aspect ratio */
@media (aspect-ratio: 2/1) {
    ...
}

/* Minimum aspect ratio */
@media (min-aspect-ratio: 16/9) {
    ...
}

/* Maximum aspect ratio */
@media (max-aspect-ratio: 8/5) {
    ...
}

Both, orientation and aspect-ratio depend on the actual size of the viewport and have nothing todo with the device orientation itself.

After making the id unique across the document ,You have to use event delegation

$("#container").on("click", "buttonid", function () {
  alert("Hi");
});

Create a div that is the line with the code like this:

CSS

div#lineHorizontal {
    background-color: #000;
    width: //the width of the line or how far it goes sidewards;
    height: 2px;
    display: inline-block;
    margin: 0px;
 }
div#block {
    background-color: #777;
    display: inline-block;
    margin: 0px;
}

HTML

<div id="block">
</div>
<div id="lineHorizontal">
</div>
<div id="block">
</div>

This will display a block with a horizontal line to another block.

On mobile devices you could use (caniuse.com/transforms2d)

You can also invoke cmake itself to do this in a cross-platform way:

cmake -E env EnvironmentVariableName="Hello World" cmake ..

env [--unset=NAME]... [NAME=VALUE]... COMMAND [ARG]...

Run command in a modified environment.

Just be aware that this may only work the first time. If CMake re-configures with one of the consecutive builds (you just call e.g. make, one CMakeLists.txt was changed and CMake runs through the generation process again), the user defined environment variable may not be there anymore (in comparison to system wide environment variables).

So I transfer those user defined environment variables in my projects into a CMake cached variable:

cmake_minimum_required(VERSION 2.6)

project(PrintEnv NONE)

if (NOT "$ENV{EnvironmentVariableName}" STREQUAL "")
    set(EnvironmentVariableName "$ENV{EnvironmentVariableName}" CACHE INTERNAL "Copied from environment variable")
endif()

message("EnvironmentVariableName = ${EnvironmentVariableName}")

• CMake - Command Line Tool Mode

When we have to use inbuilt procedures or packages we have to use "EXECUTE" command then it will work.

EX:

EXECUTE exec DBMS_MVIEW.REFRESH('v_materialized_foo_tbl');

As in the docs, if you are on windows you can use hyperv drivers.

Docker for Windows - You can use docker-machine create with the hyperv driver to create additional local machines.

Using various cheats from the web, I came to this solution:

int[] count = new int[1];
final int CHUNK_SIZE = 500;
Map<Integer, List<Long>> chunkedUsers = users.stream().collect( Collectors.groupingBy( 
    user -> {
        count[0]++;
        return Math.floorDiv( count[0], CHUNK_SIZE );
    } )
);

We use count to mimic a normal collection index.
Then, we group the collection elements in buckets, using the algebraic quotient as bucket number.
The final map contains as key the bucket number, as value the bucket itself.

You can then easily do an operation on each of the buckets with:

chunkedUsers.values().forEach( ... );

In a single-byte ASCII-compatible encoding (e.g. Latin-1), ASCII characters are simply bytes in the range 0 to 127. So you can use something like [\x80-\xFF] to detect non-ASCII characters.

For .net 4.0

Add a reference to System.net.dll to the project with using System.Net; then use the following extensions

// Html encode/decode
    public static string HtmDecode(this string htmlEncodedString)
    {
        if(htmlEncodedString.Length > 0)
        {
            return System.Net.WebUtility.HtmlDecode(htmlEncodedString);
        }
        else
        {
            return htmlEncodedString;
        }
    }

    public static string HtmEncode(this string htmlDecodedString)
    {
        if(htmlDecodedString.Length > 0)
        {
            return System.Net.WebUtility.HtmlEncode(htmlDecodedString);
        }
        else
        {
            return htmlDecodedString;
        }
    }

I had the same problem and solved it by using the default woocommerce hook to display the product image.

while ( $loop->have_posts() ) : $loop->the_post();
   echo woocommerce_get_product_thumbnail('woocommerce_full_size');
endwhile;

Available parameters:

• woocommerce_thumbnail
• woocommerce_full_size

Similar problem with an embarrassingly simple solution - make sure your API methods are public. Leaving off any method access modifier will return an HTTP 404 too.

Will return 404:

Will execute as expected:

I like to place all my sql connections in using statements. I think they look cleaner, and they clean up after themselves when your done with them. I also recommend parameterizing every query, not only is it much safer but it is easier to maintain if you need to come back and make changes.

// create/open connection
using (SqlConnection conn = new SqlConnection("Data Source=Si-6\\SQLSERVER2005;Initial Catalog=rags;Integrated Security=SSPI")
{
    try
    {
        conn.Open();

        // initialize command
        using (SqlCommand cmd = conn.CreateCommand())
        {

            // generate query with parameters
            with cmd
            {
                .CommandType = CommandType.Text;
                .CommandText = "insert into time(project,iteration) values(@name, @iteration)";
                .Parameters.Add(new SqlParameter("@name", this.name1.SelectedValue));
                .Parameters.Add(new SqlParameter("@iteration", this.iteration.SelectedValue));
                .ExecuteNonQuery();
            }
        }
    }
    catch (Exception)
    {
        //throw;
    }
    finally
    {
        if (conn != null && conn.State == ConnectionState.Open)
        {
            conn.Close;
        }
    }
}

There is a jquery plugin for this. It scrolls document to a specific element, so that it would be perfectly in the middle of viewport. It also supports animation easings so that the scroll effect would look super smooth. Check out AnimatedScroll.js.

Have you tried using Form.ShowDialog() instead of Form.Show()?

ShowDialog shows your window as modal, which means you cannot interact with the parent form until it closes.

Now you can use the aggregate. Example:

db.users.aggregate(
   [ { $sample: { size: 3 } } ]
)

See the doc.

Try the following:

POJO pojo = mapper.convertValue(singleObject, POJO.class);

or:

List<POJO> pojos = mapper.convertValue(
    listOfObjects,
    new TypeReference<List<POJO>>() { });

See conversion of LinkedHashMap for more information.

node-dev

node-dev is great alternative to both nodemon and supervisor for developers who like to get growl (or libnotify) notifications on their desktop whenever the server restarts or when there is an error or change occur in file.

Installation:

npm install -g node-dev

Use node-dev, instead of node:

node-dev app.js

Notification on Changing file so server start automatically

I found "The art of Prolog" a very good read.

This can happen if you forget to return a value from a function: it then returns None. Look at all places where you are assigning to that variable, and see if one of them is a function call where the function lacks a return statement.

https://golang.org/ref/mem#tmp_4

Program initialization runs in a single goroutine, but that goroutine may create other goroutines, which run concurrently.

If a package p imports package q, the completion of q's init functions happens before the start of any of p's.

The start of the function main.main happens after all init functions have finished.

Currently the best documentation is the source. You can take a look at it here (attrs.xml).

You can define attributes in the top <resources> element or inside of a <declare-styleable> element. If I'm going to use an attr in more than one place I put it in the root element. Note, all attributes share the same global namespace. That means that even if you create a new attribute inside of a <declare-styleable> element it can be used outside of it and you cannot create another attribute with the same name of a different type.

An <attr> element has two xml attributes name and format. name lets you call it something and this is how you end up referring to it in code, e.g., R.attr.my_attribute. The format attribute can have different values depending on the 'type' of attribute you want.

• reference - if it references another resource id (e.g, "@color/my_color", "@layout/my_layout")
• color
• boolean
• dimension
• float
• integer
• string
• fraction
• enum - normally implicitly defined
• flag - normally implicitly defined

You can set the format to multiple types by using |, e.g., format="reference|color".

enum attributes can be defined as follows:

<attr name="my_enum_attr">
  <enum name="value1" value="1" />
  <enum name="value2" value="2" />
</attr>

flag attributes are similar except the values need to be defined so they can be bit ored together:

<attr name="my_flag_attr">
  <flag name="fuzzy" value="0x01" />
  <flag name="cold" value="0x02" />
</attr>

In addition to attributes there is the <declare-styleable> element. This allows you to define attributes a custom view can use. You do this by specifying an <attr> element, if it was previously defined you do not specify the format. If you wish to reuse an android attr, for example, android:gravity, then you can do that in the name, as follows.

An example of a custom view <declare-styleable>:

<declare-styleable name="MyCustomView">
  <attr name="my_custom_attribute" />
  <attr name="android:gravity" />
</declare-styleable>

When defining your custom attributes in XML on your custom view you need to do a few things. First you must declare a namespace to find your attributes. You do this on the root layout element. Normally there is only xmlns:android="http://schemas.android.com/apk/res/android". You must now also add xmlns:whatever="http://schemas.android.com/apk/res-auto".

Example:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:whatever="http://schemas.android.com/apk/res-auto"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">

    <org.example.mypackage.MyCustomView
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:gravity="center"
      whatever:my_custom_attribute="Hello, world!" />
</LinearLayout>

Finally, to access that custom attribute you normally do so in the constructor of your custom view as follows.

public MyCustomView(Context context, AttributeSet attrs, int defStyle) {
  super(context, attrs, defStyle);

  TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.MyCustomView, defStyle, 0);

  String str = a.getString(R.styleable.MyCustomView_my_custom_attribute);

  //do something with str

  a.recycle();
}

The end. :)

You can totally avoid disabling, it is painful since html form format won't send anything related to <p> or some other label.

So you can instead put regular

<input text tag just before you have `/>

add this readonly="readonly"

It wouldn't disable your text but wouldn't change by user so it work like <p> and will send value through form. Just remove border if you would like to make it more like <p> tag

Had this happen to me when committing from Xcode 6, after I had added a directory of files and subdirectories to the project folder. The problem was that, in the Commit sheet, in the left sidebar, I had checkmarked not only the root directory that I had added, but all of its descendants too. To solve the problem, I checkmarked only the root directory. This also committed all of the descendants, as desired, with no error.

If, like me, you find you want essentially the same sorting code in more than one place, or just want to keep the code complexity down, you can abstract away the sorting itself to a separate function, to which you pass the function that does the actual work you want (which would be different at each call site, of course).

Given a map with key type K and value type V, represented as <K> and <V> below, the common sort function might look something like this Go-code template (which Go version 1 does not support as-is):

/* Go apparently doesn't support/allow 'interface{}' as the value (or
/* key) of a map such that any arbitrary type can be substituted at
/* run time, so several of these nearly-identical functions might be
/* needed for different key/value type combinations. */
func sortedMap<K><T>(m map[<K>]<V>, f func(k <K>, v <V>)) {
    var keys []<K>
    for k, _ := range m {
        keys = append(keys, k)
    }
    sort.Strings(keys)  # or sort.Ints(keys), sort.Sort(...), etc., per <K>
    for _, k := range keys {
        v := m[k]
        f(k, v)
    }
}

Then call it with the input map and a function (taking (k <K>, v <V>) as its input arguments) that is called over the map elements in sorted-key order.

So, a version of the code in the answer posted by Mingu might look like:

package main

import (
    "fmt"
    "sort"
)

func sortedMapIntString(m map[int]string, f func(k int, v string)) {
    var keys []int
    for k, _ := range m {
        keys = append(keys, k)
    }
    sort.Ints(keys)
    for _, k := range keys {
        f(k, m[k])
    }
}

func main() {
    // Create a map for processing
    m := make(map[int]string)
    m[1] = "a"
    m[2] = "c"
    m[0] = "b"

    sortedMapIntString(m,
        func(k int, v string) { fmt.Println("Key:", k, "Value:", v) })
}

The sortedMapIntString() function can be re-used for any map[int]string (assuming the same sort order is desired), keeping each use to just two lines of code.

Downsides include:

• It's harder to read for people unaccustomed to using functions as first-class
• It might be slower (I haven't done performance comparisons)

Other languages have various solutions:

• If the use of <K> and <V> (to denote types for the key and value) looks a bit familiar, that code template is not terribly unlike C++ templates.
• Clojure and other languages support sorted maps as fundamental data types.
• While I don't know of any way Go makes range a first-class type such that it could be substituted with a custom ordered-range (in place of range in the original code), I think some other languages provide iterators that are powerful enough to accomplish the same thing.

public void ChangePassword(int userId, string password)
{
  var user = new User{ Id = userId, Password = password };
  using (var db = new DbContextName())
  {
    db.Entry(user).State = EntityState.Added;
    db.SaveChanges();
  }
}

Thats not possible. PHP is a Server side language and JavaScript client side and they don't really know a lot about each other. You would need a Server sided JavaScript Interpreter (like Aptanas Jaxer). Maybe what you actually want to do is to use an Ajax like Architecture (JavaScript function calls PHP script asynchronously and does something with the result).

<td onClick= loadxml()><i>Click for Details</i></td>

function loadxml()
{
    result = loadScriptWithAjax("/script.php?event=button_clicked");
    alert(result);
}

// script.php
<?php
    if($_GET['event'] == 'button_clicked')
        echo "\"You clicked a button\"";
?>

You can pass input as ["apple","orange"]if you want to leave the method as it is.

It worked for me with a similar method signature.

I know this is an oldish post but I made this answer for another site so I thought I'd post it up here:

UPPER -> lower: use python:

b=`echo "print '$a'.lower()" | python`

Or Ruby:

b=`echo "print '$a'.downcase" | ruby`

Or Perl:

b=`perl -e "print lc('$a');"`

Or PHP:

b=`php -r "print strtolower('$a');"`

Or Awk:

b=`echo "$a" | awk '{ print tolower($1) }'`

Or Sed:

b=`echo "$a" | sed 's/./\L&/g'`

Or Bash 4:

b=${a,,}

Or NodeJS:

b=`node -p "\"$a\".toLowerCase()"`

You could also use dd:

b=`echo "$a" | dd  conv=lcase 2> /dev/null`

lower -> UPPER:

use python:

b=`echo "print '$a'.upper()" | python`

Or Ruby:

b=`echo "print '$a'.upcase" | ruby`

Or Perl:

b=`perl -e "print uc('$a');"`

Or PHP:

b=`php -r "print strtoupper('$a');"`

Or Awk:

b=`echo "$a" | awk '{ print toupper($1) }'`

Or Sed:

b=`echo "$a" | sed 's/./\U&/g'`

Or Bash 4:

b=${a^^}

Or NodeJS:

b=`node -p "\"$a\".toUpperCase()"`

You could also use dd:

b=`echo "$a" | dd  conv=ucase 2> /dev/null`

Also when you say 'shell' I'm assuming you mean bash but if you can use zsh it's as easy as

b=$a:l

for lower case and

b=$a:u

for upper case.

I would do it like this:

Worksheets("EmployeeCosts").Range("B" & var1a).Formula = _
Replace("=SUM(H5:H{SOME_VAR})","{SOME_VAR}",var1a)

In case you have some more complex formula it will be handy

I just do this and call it a day

Model.Id > -1 ? Html.EnumDropDownListFor(m => m.Property, new { disabled = "disabled" }) : Html.EnumDropDownListFor(m => m.Property)

An analytic solution with only one nested query:

SELECT * FROM
(
   SELECT t.*, Row_Number() OVER (ORDER BY name) MyRow FROM sometable t
) 
WHERE MyRow BETWEEN 10 AND 20;

Rank() could be substituted for Row_Number() but might return more records than you are expecting if there are duplicate values for name.

Open up terminal first and then go to directory of web server

cd /Library/WebServer/Documents

and then type this and what you will do is you will give read and write permission

sudo chmod -R o+w /Library/WebServer/Documents

This will surely work!

EJS seems to behave differently depending on whether you use { } notation or not:

I have checked and the following condition is evaluated as you would expect:

<%if (3==3) {%>  TEXT PRINTED  <%}%>
<%if (3==4) {%>  TEXT NOT PRINTED  <%}%>

while this one doesn't:

<%if (3==3) %>  TEXT PRINTED  <% %>
<%if (3==4) %>  TEXT PRINTED  <% %>  

Sorry for necroposting but faced this problem just today. For everybody also facing with this problem - one of he possible reasons - you don't call super at the first line of method. Second, third and other lines fire this error. Call of super should be very first call in your method. In this case everything is well.

Use localStorage for that. It's persistent over sessions.

Writing :

localStorage['myKey'] = 'somestring'; // only strings

Reading :

var myVar = localStorage['myKey'] || 'defaultValue';

If you need to store complex structures, you might serialize them in JSON. For example :

Reading :

var stored = localStorage['myKey'];
if (stored) myVar = JSON.parse(stored);
else myVar = {a:'test', b: [1, 2, 3]};

Writing :

localStorage['myKey'] = JSON.stringify(myVar);

Note that you may use more than one key. They'll all be retrieved by all pages on the same domain.

Unless you want to be compatible with IE7, you have no reason to use the obsolete and small cookies.

Although this question specifically asks about IntelliJ, this was the first result I received on Google, so I believe that many Eclipse users may have the same problem using Buildship.

You can set your Gradle JVM in Eclipse by going to Gradle Tasks (in the default view, down at the bottom near the console), right-clicking on the specific task you are trying to run, clicking "Open Gradle Run Configuration..." and moving to the Java Home tab and picking the correct JVM for your project.

You could set the corresponding value in the ViewData/ViewBag:

ViewData["hdnFlag"] = "some value";

But a much better approach is to of course use a view model:

model.hdnFlag = "some value";
return View(model);

and use a strongly typed helper in your view:

@Html.HiddenFor(x => x.hdnFlag, new { id = "hdnFlag" })

You're pretty much on the ball. The only difference is I'd separate out the JavaScript code so the majority was in an external static file. Then you just define variables or call a function from the actual PHP page:

<script type="text/javascript>
    function_in_other_file(<?php echo my_php_var; ?>);
</script>

The read(1) utility along with output redirection of the ls(1) command will do what you want.

As far as I can see dependencies have changed between 2.26-b03 and 2.26-b04 (HK2 was moved to from compile to testCompile)... there might be some change in the jersey dependencies that has not been completed yet (or which lead to a bug).

However, right now the simple solution is to stick to an older version :-)

Remove your nCount altogether (as there are some roots that this algorithm will take many iterations for).

double SqrtNumber(double num)
{
    double lower_bound=0; 
    double upper_bound=num;
    double temp=0;

    while(fabs(num - (temp * temp)) > SOME_SMALL_VALUE)
    {
           temp = (lower_bound+upper_bound)/2;
           if (temp*temp >= num)
           {
                   upper_bound = temp;
           }
           else
           {
                   lower_bound = temp;
           }
    }
    return temp;
 }

.hover() function accepts two function arguments, one for mouseenter event and one for mouseleave event.

Map is an interface; HashMap is a particular implementation of that interface.

HashMap uses a collection of hashed key values to do its lookup. TreeMap will use a red-black tree as its underlying data store.

Here is an alternative for that experiment (Swift 3.0). This tells you exactly which kind of number was the largest.

let interestingNumbers = [
"Prime": [2, 3, 5, 7, 11, 13],
"Fibonacci": [1, 1, 2, 3, 5, 8],
"Square": [1, 4, 9, 16, 25],
]

var largest = 0
var whichKind: String? = nil

for (kind, numbers) in interestingNumbers {
    for number in numbers {
    if number > largest {
        whichKind = kind
        largest = number
    }
  }
}

print(whichKind)
print(largest)

OUTPUT:
Optional("Square")
25

A keystore needs a keystore file. The KeyStore class needs a FileInputStream. But if you supply null (instead of FileInputStream instance) an empty keystore will be loaded. Once you create a keystore, you can verify its integrity using keytool.

Following code creates an empty keystore with empty password

  KeyStore ks2 = KeyStore.getInstance("jks");
  ks2.load(null,"".toCharArray());
  FileOutputStream out = new FileOutputStream("C:\\mykeytore.keystore");
  ks2.store(out, "".toCharArray());

Once you have the keystore, importing certificate is very easy. Checkout this link for the sample code.

This code snippet is working properly

Url.Action() will get you the bare URL for most overloads of Html.ActionLink, but I think that the URL-from-lambda functionality is only available through Html.ActionLink so far. Hopefully they'll add a similar overload to Url.Action at some point.

The initial post mentioned buttons. You can also replace the input tags with buttons.

<button type="submit" name="product" value="Tea">Tea</button>
<button type="submit" name="product" value="Coffee">Coffee</button>

The name and value attributes are required to submit the value when the form is submitted (the id attribute is not necessary in this case). The attribute type=submit specifies that clicking on this button causes the form to be submitted.

When the server is handling the submitted form, $_POST['product'] will contain the value "Tea" or "Coffee" depending on which button was clicked.

If you want you can also require the user to confirm before submitting the form (useful when you are implementing a delete button for example).

<button type="submit" name="product" value="Tea" onclick="return confirm('Are you sure you want tea?');">Tea</button>
<button type="submit" name="product" value="Coffee" onclick="return confirm('Are you sure you want coffee?');">Coffee</button>

Alright.. Try this: http://www.devshed.com/c/a/MySQL/Delving-Deeper-into-MySQL-50/
http://dev.mysql.com/doc/refman/5.0/en/loop-statement.html
http://www.roseindia.net/sql/mysql-example/mysql-loop.shtml

Use that to, say, generate a temp table, and then do a select * on the temp table. Or output the results one at a time.
What you say you want to do can't be done with a SELECT statement, but it might be doable with things specific to MySQL.
Then again, maybe you need cursors: http://dev.mysql.com/doc/refman/5.0/en/cursors.html

Make sure that the comma is directly after the fully qualified name

typeof(namespace.a.b.ClassName, AssemblyName)

As this wont work

typeof(namespace.a.b.ClassName ,AssemblyName)

If you are using Angular UI Bootstrap, you can use tooltip with html syntax: tooltip-html-unsafe

I found this question as I had a similar problem. While data-backdrop does "solve" the issue; I found another problem in my markup.

I had the button which launched this modal and the modal dialog itself was in the footer. The problem is that the footer was defined as navbar_fixed_bottom, and that contained position:fixed.

After I moved the dialog outside of the fixed section, everything worked as expected.

You just need to use single quotes:

$ echo "$TEST"
test
$ echo '$TEST'
$TEST

Inside single quotes special characters are not special any more, they are just normal characters.

Try using in like this:

>>> x = 'hello'
>>> y = 'll'
>>> y in x
True

Please try my pre-commit hooks, it can auto detect trailing-whitespace and remove it. Thank you!

it can work under GitBash(windows), Mac OS X and Linux!

Snapshot:

$ git commit -am "test"
auto remove trailing whitespace in foobar/main.m!
auto remove trailing whitespace in foobar/AppDelegate.m!

With regard to LittleBobbyTable's answer - NET SEND does not work on Vista or Windows 7. It has been replaced by MSG.EXE

There is a crude solution that works on all versions of Windows - A crude popup message can be sent by STARTing a new cmd.exe window that closes once a key is pressed.

start "" cmd /c "echo Hello world!&echo(&pause"

If you want your script to pause until the message box is dismissed, then you can add the /WAIT option.

start "" /wait cmd /c "echo Hello world!&echo(&pause"

Essentially it means you don't have the index you are trying to reference. For example:

df = pd.DataFrame()
df['this']=np.nan
df['my']=np.nan
df['data']=np.nan
df['data'][0]=5 #I haven't yet assigned how long df[data] should be!
print(df)

will give me the error you are referring to, because I haven't told Pandas how long my dataframe is. Whereas if I do the exact same code but I DO assign an index length, I don't get an error:

df = pd.DataFrame(index=[0,1,2,3,4])
df['this']=np.nan
df['is']=np.nan
df['my']=np.nan
df['data']=np.nan
df['data'][0]=5 #since I've properly labelled my index, I don't run into this problem!
print(df)

Hope that answers your question!

You can use ObjectMapper.convertValue(), either value by value or even for the whole list. But you need to know the type to convert to:

POJO pojo = mapper.convertValue(singleObject, POJO.class);
// or:
List<POJO> pojos = mapper.convertValue(listOfObjects, new TypeReference<List<POJO>>() { });

this is functionally same as if you did:

byte[] json = mapper.writeValueAsBytes(singleObject);
POJO pojo = mapper.readValue(json, POJO.class);

but avoids actual serialization of data as JSON, instead using an in-memory event sequence as the intermediate step.

If you are feeling particularly clever and don't want to use Regex:

char[] separators = new char[]{' ',';',',','\r','\t','\n'};

string s = "this;is,\ra\t\n\n\ntest";
string[] temp = s.Split(separators, StringSplitOptions.RemoveEmptyEntries);
s = String.Join("\n", temp);

You could wrap this in an extension method with little effort as well.

Edit: Or just wait 2 minutes and I'll end up writing it anyway :)

public static class ExtensionMethods
{
   public static string Replace(this string s, char[] separators, string newVal)
   {
       string[] temp;

       temp = s.Split(separators, StringSplitOptions.RemoveEmptyEntries);
       return String.Join( newVal, temp );
   }
}

And voila...

char[] separators = new char[]{' ',';',',','\r','\t','\n'};
string s = "this;is,\ra\t\n\n\ntest";

s = s.Replace(separators, "\n");

I have acheived this in JQuery by putting a zero width strut element above the float right, then sizing the strut (or pipe) according to parent height minus floated child's height.

Before js kicks in I am using the position absolute approach, which works but allows text flow behind. Therefore I switch to position static to enable the strut approach. (header is the parent element, cutout is the one i want bottom right, and pipe is my strut)

$("header .pipe").each(function(){
    $(this).next(".cutout").css("position","static");       
    $(this).height($(this).parent().height()-$(this).next(".cutout").height());                                                 
});

CSS

header{
    position: relative; 
}

header img.cutout{
    float:right;
    position:absolute;
    bottom:0;
    right:0;
    clear:right
}
header .pipe{
    width:0px; 
    float:right

}

The pipe must come 1st, then the cutout, then the text in the HTML order.

Follow the instructions in this Answer to format the EditText mask.

And after that, you can catch the original numbers from the masked string with:

String phoneNumbers = maskedString.replaceAll("[^\\d]", "");

In ASP.NET Core, there are configuration providers for reading configurations from almost anywhere such as files e.g. JSON, INI or XML, environment variables, Azure key vault, command-line arguments, etc. and many more sources. I have written a step by step guide to show you how can you configure your application settings in various files such as JSON, INI or XML and how can you read those settings from your application code. I will also demonstrate how can you read application settings as custom .NET types (classes) and how can you use the built-in ASP.NET Core dependency injection to read your configuration settings in multiple classes, services or even projects available in your solution.

JSESSIONID cookie is created/sent when session is created. Session is created when your code calls request.getSession() or request.getSession(true) for the first time. If you just want to get the session, but not create it if it doesn't exist, use request.getSession(false) -- this will return you a session or null. In this case, new session is not created, and JSESSIONID cookie is not sent. (This also means that session isn't necessarily created on first request... you and your code are in control when the session is created)

Sessions are per-context:

SRV.7.3 Session Scope

HttpSession objects must be scoped at the application (or servlet context) level. The underlying mechanism, such as the cookie used to establish the session, can be the same for different contexts, but the object referenced, including the attributes in that object, must never be shared between contexts by the container.

(Servlet 2.4 specification)

Update: Every call to JSP page implicitly creates a new session if there is no session yet. This can be turned off with the session='false' page directive, in which case session variable is not available on JSP page at all.

In late 2017 Proxool, BoneCP, C3P0, DBCP are mostly defunct at this time. HikariCP (created in 2012) seems promising, blows the doors off anything else I know of. http://www.baeldung.com/hikaricp

Proxool has a number of issues:
- Under heavy load can exceed max number of connections and not return below max
- Can manage to not return to min connections even after connections expire
- Can lock up the entire pool (and all server/client threads) if it has trouble connecting to the database during HouseKeeper thread (does not use .setQueryTimeout)
- HouseKeeper thread, while having connection pool lock for its process, requests the Prototyper thread to recreate connections (sweep) which can result in race condition/lockup. In these method calls the last parameter should always be sweep:false during the loop, only sweep:true below it.
- HouseKeeper only needs the single PrototypeController sweep at the end and has more [mentioned above]
- HouseKeeper thread checks for testing of connections before seeing what connections may be expired [some risk of testing expired connection that may be broken/terminated through other timeouts to DB in firewall, etc.]
- The project has unfinished code (properties that are defined but not acted upon)
- The Default max connection life if not defined is 4 hours (excessive)
- HouseKeeper thread runs every five seconds per pool (excessive)

You can modify the code and make these improvements. But as it was created in 2003, and updated in 2008, its lacking nearly 10 years of java improvements that solutions like hikaricp utilize.

Use the filename property like this:

uriContent = "data:application/octet-stream;filename=filename.txt," + 
              encodeURIComponent(codeMirror.getValue());
newWindow=window.open(uriContent, 'filename.txt');

EDIT:

Apparently, there is no reliable way to do this. See: Is there any way to specify a suggested filename when using data: URI?

Perhaps not in the context that you have it, but you could use

SELECT DISTINCT col1,
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1),
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1, col3),
FROM TableA

You would use this to return different levels of aggregation returned in a single row. The use case would be for when a single grouping would not suffice all of the aggregates needed.

I know this is an old thread, but thought I'd put my two cents in. Ternary operators are able to be nested in the following fashion:

var variable = conditionA ? valueA : (conditionB ? valueB: (conditionC ? valueC : valueD));

Example:

var answer = value === 'foo' ? 1 :
    (value === 'bar' ? 2 : 
        (value === 'foobar' ? 3 : 0));

This started as a comment on RGB's solution but I could not fit it in so have converted it to an answer. The inspiration for which is entirely RGB's.

RGB's solution worked for me. However, I wished to note a couple of points which may help others arriving at this post (like me) who are not that familiar which SVG and who may very well have generated their SVG file from a graphics package (as I had).

So to apply RGB's solutions I used:

The CSS

 <style>
    rect.btn {
        stroke:#fff;
        fill:#fff;
        fill-opacity:0;
        stroke-opacity:0;
    }
</style>

The jquery script

<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>   
<script type="text/javascript">
   $("document").ready(function(){
       $(".btn").bind("click", function(event){alert("clicked svg")});
   });
</script>

The HTML to code the inclusion of your pre-existing SVG file in the group tag inside the SVG code.

<div>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
  <g>
     <image x="0" y="0" width="10" height="10"
     xlink:href="../_public/_icons/booked.svg" width="10px"/>
    <rect class="btn" x="0" y="0" width="10" height="10"/>

  </g>
</svg>
</div>

However, in my case I have several SVG icons which I wish to be clickable and incorporating each of these into the SVG tag was starting to become cumbersome.

So as an alternative approach where I could employ Classes I used jquery.svg. This is probably a shameful application of this plugin which can do all sorts of stuff with SVG's. But it worked using the following code:

        } 
    });

where HTML

<div class="svgload" style="width: 10px; height: 10px;"></div>

The advantage to my thinking is that I can use the appropriate class where ever the icons are needed and avoid quite a lot of code in the body of the HTML which aids readability. And I only need to incorporate the pre-existing SVG file once.

Edit: Here is a neater version of the script courtesy of Keith Wood: using .svg's load URL setting.

<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>       
<script type="text/javascript" src="jquery.svg.min.js"></script>
<script type="text/javascript">
    $("document").ready(function(){

      $('.svgload').on('click', function() {
          alert('clicked svg new');
      }).svg({loadURL: '../_public/_icons/booked.svg'});

    });
</script>

Here's a quick sample using the DecimalFormat class mentioned by Nick.

float f = 12.345f;
DecimalFormat df = new DecimalFormat("#.00");
System.out.println(df.format(f));

The output of the print statement will be 12.35. Notice that it will round it for you.

There is at least one way, but it's not a very good one. You could just poll the element for changes like this:

var previous_style,
    poll = window.setInterval(function()
{
    var current_style = document.getElementById('target').style.display;
    if (previous_style != current_style) {
        alert('style changed');
        window.clearInterval(poll);
    } else {
        previous_style = current_style;
    }
}, 100);

The DOM standard also specifies mutation events, but I've never had the chance to use them, and I'm not sure how well they're supported. You'd use them like this:

target.addEventListener('DOMAttrModified', function()
{
    if (e.attrName == 'style') {
        alert('style changed');
    }
}, false);

This code is off the top of my head, so I'm not sure if it'd work.

The best and easiest solution would be to have a callback in the function displaying your target.

Why javascript?

<meta http-equiv="REFRESH" content="0;url=http://www.URL2.com">

Unless I'm missunderstanding...

Had the same kind of problem and in fact the problem was not the function nor the function call, but what I passed as arguments to the function.

The function was called from the body of the script - the 'main' - so I passed "st1 a b" "st2 c d" "st3 e f" from the command line and passed it over to the function using myFunction $*

The $* causes the problem as it expands into a set of characters which will be interpreted in the call to the function using whitespace as a delimiter.

The solution was to change the call to the function in explicit argument handling from the 'main' towards the function : the call would then be myFunction "$1" "$2" "$3" which will preserve the whitespace inside strings as the quotes will delimit the arguments ... So if a parameter can contain spaces, it should be handled explicitly throughout all calls of functions.

As this may be the reason for long searches to problems, it may be wise never to use $* to pass arguments ...

Hope this helps someone, someday, somewhere ... Jan.

If you are using PHP you can use this, and I'm sure it's almost similar in other languages as well

$WebsiteURL = "https://api.telegram.org/bot".$BotToken;
$text = "<b>This</b> <i>is some Text</i>";
$Update = file_get_contents($WebsiteURL."/sendMessage?chat_id=$chat_id&text=$text&parse_mode=html);

echo $Update;

Here is the list of all tags that you can use

<b>bold</b>, <strong>bold</strong>
<i>italic</i>, <em>italic</em>
<a href="http://www.example.com/">inline URL</a>
<code>inline fixed-width code</code>
<pre>pre-formatted fixed-width code block</pre>

Really the ideal way to do this is to not use pull at all, but instead fetch and reset:

git fetch origin master
git reset --hard FETCH_HEAD
git clean -df

(Altering master to whatever branch you want to be following.)

pull is designed around merging changes together in some way, whereas reset is designed around simply making your local copy match a specific commit.

You may want to consider slightly different options to clean depending on your system's needs.

Easiest way

The most trivial way to upload a binary file to an FTP server using PowerShell is using WebClient.UploadFile:

$client = New-Object System.Net.WebClient
$client.Credentials = New-Object System.Net.NetworkCredential("username", "password")
$client.UploadFile("ftp://ftp.example.com/remote/path/file.zip", "C:\local\path\file.zip")

Advanced options

If you need a greater control, that WebClient does not offer (like TLS/SSL encryption, etc), use FtpWebRequest. Easy way is to just copy a FileStream to FTP stream using Stream.CopyTo:

$request = [Net.WebRequest]::Create("ftp://ftp.example.com/remote/path/file.zip")
$request.Credentials = New-Object System.Net.NetworkCredential("username", "password")
$request.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile 

$fileStream = [System.IO.File]::OpenRead("C:\local\path\file.zip")
$ftpStream = $request.GetRequestStream()

$fileStream.CopyTo($ftpStream)

$ftpStream.Dispose()
$fileStream.Dispose()

Progress monitoring

If you need to monitor an upload progress, you have to copy the contents by chunks yourself:

$request = [Net.WebRequest]::Create("ftp://ftp.example.com/remote/path/file.zip")
$request.Credentials = New-Object System.Net.NetworkCredential("username", "password")
$request.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile 

$fileStream = [System.IO.File]::OpenRead("C:\local\path\file.zip")
$ftpStream = $request.GetRequestStream()

$buffer = New-Object Byte[] 10240
while (($read = $fileStream.Read($buffer, 0, $buffer.Length)) -gt 0)
{
    $ftpStream.Write($buffer, 0, $read)
    $pct = ($fileStream.Position / $fileStream.Length)
    Write-Progress `
        -Activity "Uploading" -Status ("{0:P0} complete:" -f $pct) `
        -PercentComplete ($pct * 100)
}

$ftpStream.Dispose()
$fileStream.Dispose()

Uploading folder

If you want to upload all files from a folder, see
PowerShell Script to upload an entire folder to FTP

Because the SCHEDULER_ADMIN role is a powerful role allowing a grantee to execute code as any user, you should consider granting individual Scheduler system privileges instead. Object and system privileges are granted using regular SQL grant syntax. An example is if the database administrator issues the following statement:

GRANT CREATE JOB TO scott;

After this statement is executed, scott can create jobs, schedules, or programs in his schema.

copied from http://docs.oracle.com/cd/B19306_01/server.102/b14231/schedadmin.htm#i1006239

I would rather use the Date valueOf method instead of === or !==

Seems like === is comparing internal Object's references and nothing concerning date.

You don't need a regex for this. Use tr:

"some text\nandsomemore".tr("\n","")

Here is a more complete example using a fieldset for accessibility reasons and specifying the first button as the default. Without a fieldset, what the radio buttons are for as a whole can not be programmatically determined.

Model

public class MyModel
{
    public bool IsMarried { get; set; }
}

View

<fieldset>
    <legend>Married</legend>

    @Html.RadioButtonFor(e => e.IsMarried, true, new { id = "married-true" })
    @Html.Label("married-true", "Yes")

    @Html.RadioButtonFor(e => e.IsMarried, false, new { id = "married-false" })
    @Html.Label("married-false", "No")
</fieldset>

You can add a @checked argument to the anonymous object to set the radio button as the default:

new { id = "married-true", @checked = 'checked' }

Note that you can bind to a string by replacing true and false with the string values.

Infinitive progress bar using pure Javascript

<div id="container" style="width:100%; height:5px; border:1px solid black;">
  <div id="progress-bar" style="width:10%;background-color: green; height:5px;"></div>
</div>

<script>
  var width = 0;
  window.onload = function(e){ 
    setInterval(function () {
        width = width >= 100 ? 0 : width+5;  
        document.getElementById('progress-bar').style.width = width + '%'; }, 200);            
  }
</script>

Why not to try this?

Swift code to call inside class:

self.mainFrame.reload()

or external call

myWebV.mainFrame.reload()

Both methods achieve the same purpose, to forego unnecessary db queries. But they use different approaches for efficiency.

The only reason to use either of these methods is when a single large query is preferable to many small queries. Django uses the large query to create models in memory preemptively rather than performing on demand queries against the database.

select_related performs a join with each lookup, but extends the select to include the columns of all joined tables. However this approach has a caveat.

Joins have the potential to multiply the number of rows in a query. When you perform a join over a foreign key or one-to-one field, the number of rows won't increase. However, many-to-many joins do not have this guarantee. So, Django restricts select_related to relations that won't unexpectedly result in a massive join.

The "join in python" for prefetch_related is a little more alarming then it should be. It creates a separate query for each table to be joined. It filters each of these table with a WHERE IN clause, like:

SELECT "credential"."id",
       "credential"."uuid",
       "credential"."identity_id"
FROM   "credential"
WHERE  "credential"."identity_id" IN
    (84706, 48746, 871441, 84713, 76492, 84621, 51472);

Rather than performing a single join with potentially too many rows, each table is split into a separate query.

The ideal solution would be as below. You won't miss the values from 0 to n.

$len=count($data);
for($i=0;$i<$len;$i++)
     echo $data[$i]. "<br>";

The lazy-init="default" setting on a bean only refers to what is set by the default-lazy-init attribute of the enclosing beans element. The implicit default value of default-lazy-init is false.

If there is no lazy-init attribute specified on a bean, it's always eagerly instantiated.

As mentioned by few users, below code can help find all the fields in a given class.

TestClass testObject= new TestClass().getClass();
Method[] methods = testObject.getMethods();
for (Method method:methods)
{
    String name=method.getName();
    if(name.startsWith("get"))
    {
        System.out.println(name.substring(3));
    }else if(name.startsWith("is"))
    {
        System.out.println(name.substring(2));
    }
}

However a more interesting approach is below:

With the help of Jackson library, I was able to find all class properties of type String/integer/double, and respective values in a Map class. (without using reflections api!)

TestClass testObject = new TestClass();
com.fasterxml.jackson.databind.ObjectMapper m = new com.fasterxml.jackson.databind.ObjectMapper();

Map<String,Object> props = m.convertValue(testObject, Map.class);

for(Map.Entry<String, Object> entry : props.entrySet()){
    if(entry.getValue() instanceof String || entry.getValue() instanceof Integer || entry.getValue() instanceof Double){
        System.out.println(entry.getKey() + "-->" + entry.getValue());
    }
}

If you want to add a dictionary within a dictionary you can do it this way.

Example: Add a new entry to your dictionary & sub dictionary

dictionary = {}
dictionary["new key"] = "some new entry" # add new dictionary entry
dictionary["dictionary_within_a_dictionary"] = {} # this is required by python
dictionary["dictionary_within_a_dictionary"]["sub_dict"] = {"other" : "dictionary"}
print (dictionary)

Output:

{'new key': 'some new entry', 'dictionary_within_a_dictionary': {'sub_dict': {'other': 'dictionarly'}}}

NOTE: Python requires that you first add a sub

dictionary["dictionary_within_a_dictionary"] = {}

before adding entries.

Do you even need MSDTC? The escalation you're experiencing is often caused by creating multiple connections within a single TransactionScope.

If you do need it then you need to enable it as outlined in the error message. On XP:

• Go to Administrative Tools -> Component Services
• Expand Component Services -> Computers ->
• Right-click -> Properties -> MSDTC tab
• Hit the Security Configuration button

Had the same exception. In my case, I had to run Command Prompt with Administrator Rights.

From the Start Menu, right click on Command Prompt, select "Run as administrator".

Code for WebTestPlugIn

public class Protocols : WebTestPlugin
{

    public override void PreRequest(object sender, PreRequestEventArgs e)
    {
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

    }

}

It turns out I was just missing DECIMAL on the CAST() description:

DECIMAL[(M[,D])]

Converts a value to DECIMAL data type. The optional arguments M and D specify the precision (M specifies the total number of digits) and the scale (D specifies the number of digits after the decimal point) of the decimal value. The default precision is two digits after the decimal point.

Thus, the following query worked:

UPDATE table SET
latitude = CAST(old_latitude AS DECIMAL(10,6)),
longitude = CAST(old_longitude AS DECIMAL(10,6));

It'll be good to see the csv file itself, but this might work for you, give it a try, replace:

file_read = csv.reader(self.file)

with:

file_read = csv.reader(self.file, dialect=csv.excel_tab)

Or, open a file with universal newline mode and pass it to csv.reader, like:

reader = csv.reader(open(self.file, 'rU'), dialect=csv.excel_tab)

Or, use splitlines(), like this:

def read_file(self):
    with open(self.file, 'r') as f:
        data = [row for row in csv.reader(f.read().splitlines())]
    return data

just add on table

style="overflow-x:auto;"

<table border=1 id="qandatbl" align="center" style="overflow-x:auto;">_x000D_
    <tr>_x000D_
    <th class="col1">Question No</th>_x000D_
    <th class="col2">Option Type</th>_x000D_
    <th class="col1">Duration</th>_x000D_
    </tr>_x000D_
_x000D_
   <tbody>_x000D_
    <tr>_x000D_
    <td class='qid'></td>_x000D_
    <td class="options"></td>_x000D_
    <td class="duration"></td>_x000D_
    </tr>_x000D_
    </tbody>_x000D_
</table>

style="overflow-x:auto;"`

Alternatively (just for comparison), if you have Rails installed (actually just ActiveSupport):

require 'activesupport'
array.sum

Nice way to do this with LINQ...

var data = new byte[] { 1, 2, 4, 8, 16, 32 }; 
var hexString = data.Aggregate(new StringBuilder(), 
                               (sb,v)=>sb.Append(v.ToString("X2"))
                              ).ToString();

Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.

This worked fine for me:

else if(requestCode == GALLERY_ACTIVITY_NEW && resultCode == Activity.RESULT_OK)
{
    Uri uri = data.getData();
    Log.i(TAG, "old uri =  " + uri);
    dumpImageMetaData(uri);

    try {
        ParcelFileDescriptor parcelFileDescriptor =
                getContentResolver().openFileDescriptor(uri, "r");
        FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
        Log.i(TAG, "File descriptor " + fileDescriptor.toString());

        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFileDescriptor(fileDescriptor, null, options);

        options.inSampleSize =
           BitmapHelper.calculateInSampleSize(options,
                                              User.PICTURE_MAX_WIDTH_IN_PIXELS,
                                              User.PICTURE_MAX_HEIGHT_IN_PIXELS);
        options.inJustDecodeBounds = false;

        Bitmap bitmap = BitmapFactory.decodeFileDescriptor(fileDescriptor, null, options);
        imageViewPic.setImageBitmap(bitmap);

        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
        // get byte array here
        byte[] picData = stream.toByteArray();
        ParseFile picFile = new ParseFile(picData);
        user.setProfilePicture(picFile);
    }
    catch(FileNotFoundException exc)
    {
        Log.i(TAG, "File not found: " + exc.toString());
    }
}

I hope, this short code is useful for You,

Old thread, but it's worth mentioning that Apple introduced NSRegularExpression in iOS 4.0. (Taking the regular expression from Peter's response)

// Look for 0-n digits from start to finish
NSRegularExpression *noFunnyStuff = [NSRegularExpression regularExpressionWithPattern:@"^(?:|0|[1-9]\\d*)(?:\\.\\d*)?$" options:0 error:nil];

// There should be just one match
if ([noFunnyStuff numberOfMatchesInString:<#theString#> options:0 range:NSMakeRange(0, <#theString#>.length)] == 1)
{
    // Yay, digits!
}

I suggest storing the NSRegularExpression instance somewhere.

The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts

• Talk to the server developer for more info. You can't get more info directly.
• Verify your arguments into the call (values). Look for anything you might think could cause a problem for the server process. The process should not die and should return you a better code, but bugs happen there also.
• Could be intermittent, like if the server database goes down. May be worth trying at another time.

You can easily do this using node-fetch if you are pulling from http(s) URIs.

fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png')
    .then(res => res.buffer())
    .then(buffer => console.log)

If you need your SVGs to be fully styleable with CSS they have to be inline in the DOM. This can be achieved through SVG injection, which uses Javascript to replace a HTML element (usually an <img> element) with the contents of an SVG file after the page has loaded.

Here is a minimal example using SVGInject:

<html>
<head>
  <script src="svg-inject.min.js"></script>
</head>
<body>
  <img src="image.svg" onload="SVGInject(this)" />
</body>
</html>

After the image is loaded the onload="SVGInject(this) will trigger the injection and the <img> element will be replaced by the contents of the file provided in the src attribute. This works with all browsers that support SVG.

Disclaimer: I am the co-author of SVGInject

Because tuple(3, 4) is not the correct syntax to create a tuple. The correct syntax is -

tuple([3, 4])

or

(3, 4)

You can see it from here - https://docs.python.org/2/library/functions.html#tuple

My solution was to make all the parents 100% and set a specific percentage for each row:

html, body,div[class^="container"] ,.column {
    height: 100%;
}

.row0 {height: 10%;}
.row1 {height: 40%;}
.row2 {height: 50%;}

exec is for statement and does not return anything. eval is for expression and returns value of expression.

expression means "something" while statement means "do something".

To dynamically change the color of a text box goto properties, goto font/Color and set the following expression

=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)

Same way for tolerance

=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")

To avoid this sort of trouble, you can use replace (which takes a plain string) instead of replaceAll (which takes a regular expression). You will still need to escape backslashes, but not in the wild ways required with regular expressions.

Here is what I ended up doing and it worked great.

First I moved the file input outside of the form so that it is not submitted:

<input name="imagefile[]" type="file" id="takePictureField" accept="image/*" onchange="uploadPhotos(\'#{imageUploadUrl}\')" />
<form id="uploadImageForm" enctype="multipart/form-data">
    <input id="name" value="#{name}" />
    ... a few more inputs ... 
</form>

Then I changed the uploadPhotos function to handle only the resizing:

window.uploadPhotos = function(url){
    // Read in file
    var file = event.target.files[0];

    // Ensure it's an image
    if(file.type.match(/image.*/)) {
        console.log('An image has been loaded');

        // Load the image
        var reader = new FileReader();
        reader.onload = function (readerEvent) {
            var image = new Image();
            image.onload = function (imageEvent) {

                // Resize the image
                var canvas = document.createElement('canvas'),
                    max_size = 544,// TODO : pull max size from a site config
                    width = image.width,
                    height = image.height;
                if (width > height) {
                    if (width > max_size) {
                        height *= max_size / width;
                        width = max_size;
                    }
                } else {
                    if (height > max_size) {
                        width *= max_size / height;
                        height = max_size;
                    }
                }
                canvas.width = width;
                canvas.height = height;
                canvas.getContext('2d').drawImage(image, 0, 0, width, height);
                var dataUrl = canvas.toDataURL('image/jpeg');
                var resizedImage = dataURLToBlob(dataUrl);
                $.event.trigger({
                    type: "imageResized",
                    blob: resizedImage,
                    url: dataUrl
                });
            }
            image.src = readerEvent.target.result;
        }
        reader.readAsDataURL(file);
    }
};

As you can see I'm using canvas.toDataURL('image/jpeg'); to change the resized image into a dataUrl adn then I call the function dataURLToBlob(dataUrl); to turn the dataUrl into a blob that I can then append to the form. When the blob is created, I trigger a custom event. Here is the function to create the blob:

/* Utility function to convert a canvas to a BLOB */
var dataURLToBlob = function(dataURL) {
    var BASE64_MARKER = ';base64,';
    if (dataURL.indexOf(BASE64_MARKER) == -1) {
        var parts = dataURL.split(',');
        var contentType = parts[0].split(':')[1];
        var raw = parts[1];

        return new Blob([raw], {type: contentType});
    }

    var parts = dataURL.split(BASE64_MARKER);
    var contentType = parts[0].split(':')[1];
    var raw = window.atob(parts[1]);
    var rawLength = raw.length;

    var uInt8Array = new Uint8Array(rawLength);

    for (var i = 0; i < rawLength; ++i) {
        uInt8Array[i] = raw.charCodeAt(i);
    }

    return new Blob([uInt8Array], {type: contentType});
}
/* End Utility function to convert a canvas to a BLOB      */

Finally, here is my event handler that takes the blob from the custom event, appends the form and then submits it.

/* Handle image resized events */
$(document).on("imageResized", function (event) {
    var data = new FormData($("form[id*='uploadImageForm']")[0]);
    if (event.blob && event.url) {
        data.append('image_data', event.blob);

        $.ajax({
            url: event.url,
            data: data,
            cache: false,
            contentType: false,
            processData: false,
            type: 'POST',
            success: function(data){
               //handle errors...
            }
        });
    }
});

var filtered = Directory.GetFiles(path)
    .Where(file => file.EndsWith("aspx", StringComparison.InvariantCultureIgnoreCase) || file.EndsWith("ascx", StringComparison.InvariantCultureIgnoreCase))
    .ToList();

Use the dimension type of resources like you use string resources (DOCS).

In your dimens.xml file, declare your dimension variables:

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <dimen name="textview_height">25dp</dimen>
  <dimen name="textview_width">150dp</dimen>
  <dimen name="ball_radius">30dp</dimen>
  <dimen name="font_size">16sp</dimen>
</resources>

Then you can use these values like this:

<TextView
   android:layout_height="@dimen/textview_height"
   android:layout_width="@dimen/textview_width"
   android:textSize="@dimen/font_size"/>

You can declare different dimens.xml files for different types of screens. Doing this will guarantee the desired look of your app on different devices.

When you don't specify android:textSize the system uses the default values.

Use the join method from the Array type.

a.value = [a, b, c, d, e, f];
var stringValueYouWant = a.join();

The join method will return a string that is the concatenation of all the array elements. It will use the first parameter you pass as a separator - if you don't use one, it will use the default separator, which is the comma.

There is an api in Express.

res.sendFile

app.get('/report/:chart_id/:user_id', function (req, res) {
    // res.sendFile(filepath);
});

http://expressjs.com/en/api.html#res.sendFile

This is easily achieved in ES6;

You can convert strings to Arrays with Array.from('string');

Array.from("01")

will console.log

['0', '1']

Which is exactly what you're looking for.

Instead of building a single file and bind Ctrl+S to trigger that build I would recommend to start tsc in watch mode using the following tasks.json file:

{
    "version": "0.1.0",
    "command": "tsc",
    "isShellCommand": true,
    "args": ["-w", "-p", "."],
    "showOutput": "silent",
    "isWatching": true,
    "problemMatcher": "$tsc-watch"
}

This will once build the whole project and then rebuild the files that get saved independent of how they get saved (Ctrl+S, auto save, ...)

RMDIR or RD if you are using the classic Command Prompt (cmd.exe):

rd /s /q "path"

RMDIR [/S] [/Q] [drive:]path

RD [/S] [/Q] [drive:]path

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

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

If you are using PowerShell you can use Remove-Item (which is aliased to del, erase, rd, ri, rm and rmdir) and takes a -Recurse argument that can be shorted to -r

rd -r "path"

By far the simplest (works for python) is '123-(apple|banana)-?456'.

I highly recommend Loopj.

I have successfully used it to upload multiple files at once, including different mime types. Simply do this:

File myVideo = new File("/path/to/myvideo.mp4");
File myPic = new File("/path/to/mypic.jpg");
RequestParams params = new RequestParams();
try {
  params.put("profile_picture", myPic);
  params.put("my_video", myVideo);
} catch(FileNotFoundException e) {}

For large or many files you might have to increase the timeout amount else the default timeout is used which might be too short:

client.setTimeout(500000) //make this the appropriate timeout in milliseconds

Please see this links for a full description of loopj and how to use it, by far the easiest async http library I have come across:

http://loopj.com/android-async-http/ http://loopj.com/android-async-http/doc/com/loopj/android/http/AsyncHttpClient.html

bool point2Dtriangle(double e,double f, double a,double b,double c, double g,double h,double i, double v, double w){
    /* inputs: e=point.x, f=point.y
               a=triangle.Ax, b=triangle.Bx, c=triangle.Cx 
               g=triangle.Ay, h=triangle.By, i=triangle.Cy */
    v = 1 - (f * (b - c) + h * (c - e) + i * (e - b)) / (g * (b - c) + h * (c - a) + i * (a - b));
    w = (f * (a - b) + g * (b - e) + h * (e - a)) / (g * (b - c) + h * (c - a) + i * (a - b));
    if (*v > -0.0 && *v < 1.0000001 && *w > -0.0 && *w < *v) return true;//is inside
    else return false;//is outside
    return 0;
} 

almost perfect Cartesian coordinates converted from barycentric are exported within *v (x) and *w (y) doubles. Both export doubles should have a * char before in every case, likely: *v and *w Code can be used for the other triangle of a quadrangle too. Hereby signed wrote only triangle abc from the clockwise abcd quad.

A---B
|..\\.o|  
|....\\.| 
D---C 

the o point is inside ABC triangle for testing with with second triangle call this function CDA direction, and results should be correct after *v=1-*v; and *w=1-*w; for the quadrangle

Following document published by W3C also describes the differences between SOAP 1.1 and 1.2:

• From SOAP/1.1 to SOAP Version 1.2 in 9 points

By using the merge function and its optional parameters:

Inner join: merge(df1, df2) will work for these examples because R automatically joins the frames by common variable names, but you would most likely want to specify merge(df1, df2, by = "CustomerId") to make sure that you were matching on only the fields you desired. You can also use the by.x and by.y parameters if the matching variables have different names in the different data frames.

Outer join: merge(x = df1, y = df2, by = "CustomerId", all = TRUE)

Left outer: merge(x = df1, y = df2, by = "CustomerId", all.x = TRUE)

Right outer: merge(x = df1, y = df2, by = "CustomerId", all.y = TRUE)

Cross join: merge(x = df1, y = df2, by = NULL)

Just as with the inner join, you would probably want to explicitly pass "CustomerId" to R as the matching variable. I think it's almost always best to explicitly state the identifiers on which you want to merge; it's safer if the input data.frames change unexpectedly and easier to read later on.

You can merge on multiple columns by giving by a vector, e.g., by = c("CustomerId", "OrderId").

If the column names to merge on are not the same, you can specify, e.g., by.x = "CustomerId_in_df1", by.y = "CustomerId_in_df2" where CustomerId_in_df1 is the name of the column in the first data frame and CustomerId_in_df2 is the name of the column in the second data frame. (These can also be vectors if you need to merge on multiple columns.)

The reason is because a FileStream is returned from your method to create a file. You should return the FileStream into a variable or call the close method directly from it after the File.Create.

It is a best practice to let the using block help you implement the IDispose pattern for a task like this. Perhaps what might work better would be:

if(!File.Exists(myPath)){
   using(FileStream fs = File.Create(myPath))
   using(StreamWriter writer = new StreamWriter(fs)){
      // do your work here
   }
}

Try to see, if the service "SQL Server (MSSQLSERVER)" it's started, this solved my problem.

You can avoid the loop and cut etc by using:

awk -F ':' '{system("ping " $1);}' config.txt

However it would be better if you post a snippet of your config.txt

It appears that a button that is used as the OK or CANCEL button for a ModalPopupExtender cannot have a click event. I tested this out by removing the

OkControlID="ModalOKButton"

from the ModalPopupExtender tag, and the button click fires. I'll need to figure out another way to send the data to the server.

It is good that you've found your solution. But it is an interesting problem. I tried it out myself directly with sqlite3 (not going through rails) and did not get the same result, for me the order came out as expected.

What I suggest you to do if you want to continue digging in this problem is to start the sqlite3 command-line application and check the schema and the queries there:

This shows you the schema: .schema

And then just run the select statement as it showed up in the log files: SELECT * FROM "shows" ORDER BY date ASC, attending DESC

That way you see if:

1. The schema looks as you want it (that date is actually a date for instance)
2. That the date column actually contains a date, and not a timestamp (that is, that you don't have a time of the day that messes up the sort)

Addition to above great answers, if you want some range of IPs to be authorized, you could edit /var/lib/pgsql/{VERSION}/data file and put something like

host all all 172.0.0.0/8 trust

It will accept incoming connections from any host of the above range. Source: http://www.linuxtopia.org/online_books/database_guides/Practical_PostgreSQL_database/c15679_002.htm

In my case it is Asp.Net Core 3.1 API.

If you have a good reason to set aside culture-dependent formatting and get explicit control over whether or not there's a space between the value and the "%", and whether the "%" is leading or trailing, you can use NumberFormatInfo's PercentPositivePattern and PercentNegativePattern properties.

For example, to get a decimal value with a trailing "%" and no space between the value and the "%":

myValue.ToString("P2", new NumberFormatInfo { PercentPositivePattern = 1, PercentNegativePattern = 1 });

More complete example:

using System.Globalization; 

...

decimal myValue = -0.123m;
NumberFormatInfo percentageFormat = new NumberFormatInfo { PercentPositivePattern = 1, PercentNegativePattern = 1 };
string formattedValue = myValue.ToString("P2", percentageFormat); // "-12.30%" (in en-us)

The python seaborn module is based on matplotlib, and produces a very nice heatmap.

Below is an implementation with seaborn, designed for the ipython/jupyter notebook.

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
%matplotlib inline
# import the data directly into a pandas dataframe
nba = pd.read_csv("http://datasets.flowingdata.com/ppg2008.csv", index_col='Name  ')
# remove index title
nba.index.name = ""
# normalize data columns
nba_norm = (nba - nba.mean()) / (nba.max() - nba.min())
# relabel columns
labels = ['Games', 'Minutes', 'Points', 'Field goals made', 'Field goal attempts', 'Field goal percentage', 'Free throws made', 
          'Free throws attempts', 'Free throws percentage','Three-pointers made', 'Three-point attempt', 'Three-point percentage', 
          'Offensive rebounds', 'Defensive rebounds', 'Total rebounds', 'Assists', 'Steals', 'Blocks', 'Turnover', 'Personal foul']
nba_norm.columns = labels
# set appropriate font and dpi
sns.set(font_scale=1.2)
sns.set_style({"savefig.dpi": 100})
# plot it out
ax = sns.heatmap(nba_norm, cmap=plt.cm.Blues, linewidths=.1)
# set the x-axis labels on the top
ax.xaxis.tick_top()
# rotate the x-axis labels
plt.xticks(rotation=90)
# get figure (usually obtained via "fig,ax=plt.subplots()" with matplotlib)
fig = ax.get_figure()
# specify dimensions and save
fig.set_size_inches(15, 20)
fig.savefig("nba.png")

The output looks like this: I used the matplotlib Blues color map, but personally find the default colors quite beautiful. I used matplotlib to rotate the x-axis labels, as I couldn't find the seaborn syntax. As noted by grexor, it was necessary to specify the dimensions (fig.set_size_inches) by trial and error, which I found a bit frustrating.

As noted by Paul H, you can easily add the values to heat maps (annot=True), but in this case I didn't think it improved the figure. Several code snippets were taken from the excellent answer by joelotz.

• You can use WebClient.

• Or (if you need more fine-grained control over the request) HttpWebRequest

• Or, HttpClient in System.Net.Http.dll.

Here's a "translation" to HttpWebRequest (needed rather than WebClient in order to set the referrer). (Uses System.Net and System.IO):

    HttpWebRequest http = (HttpWebRequest)HttpWebRequest.Create(requestUrl))
    http.Referer = referrer;
    HttpWebResponse response = (HttpWebResponse )http.GetResponse();
    using (StreamReader sr = new StreamReader(response.GetResponseStream()))
    {
        string responseJson = sr.ReadToEnd();
        // more stuff
    }

This works really well:

<td><div style = "width:80px; word-wrap: break-word"> your text </div></td> 

You can use the same width for all your <div's, or adjust the width in each case to break your text wherever you like.

This way you do not have to fool around with fixed table widths, or complex css.

You need to have your DBA modify the init.ora file, adding the directory you want to access to the 'utl_file_dir' parameter. Your database instance will then need to be stopped and restarted because init.ora is only read when the database is brought up.

You can view (but not change) this parameter by running the following query:

SELECT *
  FROM V$PARAMETER
  WHERE NAME = 'utl_file_dir'

Share and enjoy.

This is quite an old question so I've updated this answer to take the HTML 5 email type into account.

You don't actually need JavaScript for this at all with HTML 5; just use the email input type:

<input type="email" />

• If you want to make it mandatory, you can add the required parameter.

• If you want to add additional RegEx validation (limit to @foo.com email addresses for example), you can use the pattern parameter, e.g.:

  <input type="email" pattern="[email protected]" />
  

There's more information available on MozDev.

Original answer follows

First off - I'd recommend the email validator RegEx from Hexillion: http://hexillion.com/samples/

It's pretty comprehensive - :

^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\]))$

I think you want a function in your JavaScript like:

function validateEmail(sEmail) {
  var reEmail = /^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\]))$/;

  if(!sEmail.match(reEmail)) {
    alert("Invalid email address");
    return false;
  }

  return true;

}

In the HTML input you need to trigger the event with an onblur - the easy way to do this is to simply add something like:

<input type="text" name="email" onblur="validateEmail(this.value);" />

Of course that's lacking some sanity checks and won't do domain verification (that has to be done server side) - but it should give you a pretty solid JS email format verifier.

Note: I tend to use the match() string method rather than the test() RegExp method but it shouldn't make any difference.

I'd make a third suggestion, Google Closure Compiler (and also the Closure Linter). You can try it out online here.

The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls.

debris = string.split("_") //explode string into array of strings indexed by "_"

debris.pop(); //pop last element off the array (which you didn't want)

result = debris.join("_"); //fuse the remainng items together like the sun

select CONCAT(Name, '(',substr(occupation, 1, 1), ')') AS f1
from OCCUPATIONS
union
select temp.str AS f1 from 
(select count(occupation) AS counts, occupation, concat('There are a total of ' ,count(occupation) ,' ', lower(occupation),'s.') As str  from OCCUPATIONS group by occupation order by counts ASC, occupation ASC
 ) As temp
 order by f1

In Bootstrap 3 they do not have separate classes for different styles of labels.

http://getbootstrap.com/components/

However, you can customize bootstrap classes that way. In your css file

.lb-sm {
  font-size: 12px;
}

.lb-md {
  font-size: 16px;
}

.lb-lg {
  font-size: 20px;
}

Alternatively, you can use header tags to change the sizes. For example, here is a medium sized label and a small-sized label

<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<h3>Example heading <span class="label label-default">New</span></h3>_x000D_
<h6>Example heading <span class="label label-default">New</span></h6>

They might add size classes for labels in future Bootstrap versions.

def is_type(df, baseType):
    import numpy as np
    import pandas as pd
    test = [issubclass(np.dtype(d).type, baseType) for d in df.dtypes]
    return pd.DataFrame(data = test, index = df.columns, columns = ["test"])
def is_float(df):
    import numpy as np
    return is_type(df, np.float)
def is_number(df):
    import numpy as np
    return is_type(df, np.number)
def is_integer(df):
    import numpy as np
    return is_type(df, np.integer)

Now, after I was pointed in the right direction, here's my complete solution:

This is the middleware class which is executed on every incoming request and checks if the request has the correct credentials. If no credentials are present or if they are wrong, the service responds with a 401 Unauthorized error immediately.

public class AuthenticationMiddleware
{
    private readonly RequestDelegate _next;

    public AuthenticationMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task Invoke(HttpContext context)
    {
        string authHeader = context.Request.Headers["Authorization"];
        if (authHeader != null && authHeader.StartsWith("Basic"))
        {
            //Extract credentials
            string encodedUsernamePassword = authHeader.Substring("Basic ".Length).Trim();
            Encoding encoding = Encoding.GetEncoding("iso-8859-1");
            string usernamePassword = encoding.GetString(Convert.FromBase64String(encodedUsernamePassword));

            int seperatorIndex = usernamePassword.IndexOf(':');

            var username = usernamePassword.Substring(0, seperatorIndex);
            var password = usernamePassword.Substring(seperatorIndex + 1);

            if(username == "test" && password == "test" )
            {
                await _next.Invoke(context);
            }
            else
            {
                context.Response.StatusCode = 401; //Unauthorized
                return;
            }
        }
        else
        {
            // no authorization header
            context.Response.StatusCode = 401; //Unauthorized
            return;
        }
    }
}

The middleware extension needs to be called in the Configure method of the service Startup class

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    app.UseMiddleware<AuthenticationMiddleware>();

    app.UseMvc();
}

And that's all! :)

Things seem to have gotten better/easier since Android 5.0 (API level 21).

I think what you're looking for is something like this:

<style name="AppTheme" parent="AppBaseTheme">
    <!-- Top-top notification/status bar color: -->
    <!--<item name="colorPrimaryDark">#000000</item>-->
    <!-- App bar color: -->
    <item name="colorPrimary">#0000FF</item>
</style>

See here for reference:

https://developer.android.com/training/material/theme.html#ColorPalette

Provide the source image (img) size as the first rectangle:

ctx.drawImage(img, 0, 0, img.width,    img.height,     // source rectangle
                   0, 0, canvas.width, canvas.height); // destination rectangle

The second rectangle will be the destination size (what source rectangle will be scaled to).

I'm going to expand your question a bit and also include the compile function.

• compile function - use for template DOM manipulation (i.e., manipulation of tElement = template element), hence manipulations that apply to all DOM clones of the template associated with the directive. (If you also need a link function (or pre and post link functions), and you defined a compile function, the compile function must return the link function(s) because the 'link' attribute is ignored if the 'compile' attribute is defined.)

• link function - normally use for registering listener callbacks (i.e., $watch expressions on the scope) as well as updating the DOM (i.e., manipulation of iElement = individual instance element). It is executed after the template has been cloned. E.g., inside an <li ng-repeat...>, the link function is executed after the <li> template (tElement) has been cloned (into an iElement) for that particular <li> element. A $watch allows a directive to be notified of scope property changes (a scope is associated with each instance), which allows the directive to render an updated instance value to the DOM.

• controller function - must be used when another directive needs to interact with this directive. E.g., on the AngularJS home page, the pane directive needs to add itself to the scope maintained by the tabs directive, hence the tabs directive needs to define a controller method (think API) that the pane directive can access/call.
  
  For a more in-depth explanation of the tabs and pane directives, and why the tabs directive creates a function on its controller using this (rather than on $scope), please see 'this' vs $scope in AngularJS controllers.

In general, you can put methods, $watches, etc. into either the directive's controller or link function. The controller will run first, which sometimes matters (see this fiddle which logs when the ctrl and link functions run with two nested directives). As Josh mentioned in a comment, you may want to put scope-manipulation functions inside a controller just for consistency with the rest of the framework.

I ended up with two changes to the original reply.

1. As of jQuery 1.8, ajaxStart and ajaxStop should only be attached to document. This makes it harder to filter only a some of the ajax requests. Soo...
2. Switching to ajaxSend and ajaxComplete makes it possible to interspect the current ajax request before showing the spinner.

This is the code after these changes:

$(document)
    .hide()  // hide it initially
    .ajaxSend(function(event, jqxhr, settings) {
        if (settings.url !== "ajax/request.php") return;
        $(".spinner").show();
    })
    .ajaxComplete(function(event, jqxhr, settings) {
        if (settings.url !== "ajax/request.php") return;
        $(".spinner").hide();
    })

Before you call setContentView(), call setTheme(android.R.style...) and just replace the ... with the theme that you want(Theme, Theme_NoTitleBar, etc.).

Or if your theme is a custom theme, then replace the entire thing, so you get setTheme(yourThemesResouceId)

Try adding this to the .htaccess file in that directory.

I've read all answers, something very important is missing here, I'll KISS. There are 2 main reasons, why I need Self-Executing Anonymous Functions, or better said "Immediately-Invoked Function Expression (IIFE)":

1. Better namespace management (Avoiding Namespace Pollution -> JS Module)
2. Closures (Simulating Private Class Members, as known from OOP)

The first one has been explained very well. For the second one, please study following example:

var MyClosureObject = (function (){
  var MyName = 'Michael Jackson RIP';
  return {
    getMyName: function () { return MyName;},
    setMyName: function (name) { MyName = name}
  }
}());

Attention 1: We are not assigning a function to MyClosureObject, further more the result of invoking that function. Be aware of () in the last line.

Attention 2: What do you additionally have to know about functions in Javascript is that the inner functions get access to the parameters and variables of the functions, they are defined within.

Let us try some experiments:

I can get MyName using getMyName and it works:

 console.log(MyClosureObject.getMyName()); 
 // Michael Jackson RIP

The following ingenuous approach would not work:

console.log(MyClosureObject.MyName); 
// undefined

But I can set an another name and get the expected result:

MyClosureObject.setMyName('George Michael RIP');
console.log(MyClosureObject.getMyName()); 
// George Michael RIP

Edit: In the example above MyClosureObject is designed to be used without the newprefix, therefore by convention it should not be capitalized.

If you have a list of lists (tracked_output_sheet in my case), where you want to delete last element from each list, you can use the following code:

interim = []
for x in tracked_output_sheet:interim.append(x[:-1])
tracked_output_sheet= interim

I was struggling with this for a while and finally found a solution on Windows 10.

Steps:

Network and Sharing Center > Change Adapter Settings > Right Click on VirtualBox Host-Only Network ( If you have multiple do the following to all of them ) > Properties > Check the VirtualBox NDUS6 Bridged Networking Driver

Imperative programming style was practiced in web development from 2005 all the way to 2013.

With imperative programming, we wrote out code that listed exactly what our application should do, step by step.

The functional programming style produces abstraction through clever ways of combining functions.

There is mention of declarative programming in the answers and regarding that I will say that declarative programming lists out some rules that we are to follow. We then provide what we refer to as some initial state to our application and we let those rules kind of define how the application behaves.

Now, these quick descriptions probably don’t make a lot of sense, so lets walk through the differences between imperative and declarative programming by walking through an analogy.

Imagine that we are not building software, but instead we bake pies for a living. Perhaps we are bad bakers and don’t know how to bake a delicious pie the way we should.

So our boss gives us a list of directions, what we know as a recipe.

The recipe will tell us how to make a pie. One recipe is written in an imperative style like so:

1. Mix 1 cup of flour
2. Add 1 egg
3. Add 1 cup of sugar
4. Pour the mixture into a pan
5. Put the pan in the oven for 30 minutes and 350 degrees F.

The declarative recipe would do the following:

1 cup of flour, 1 egg, 1 cup of sugar - initial State

Rules

1. If everything mixed, place in pan.
2. If everything unmixed, place in bowl.
3. If everything in pan, place in oven.

So imperative approaches are characterized by step by step approaches. You start with step one and go to step 2 and so on.

You eventually end up with some end product. So making this pie, we take these ingredients mix them, put it in a pan and in the oven and you got your end product.

In a declarative world, its different.In the declarative recipe we would separate our recipe into two separate parts, start with one part that lists the initial state of the recipe, like the variables. So our variables here are the quantities of our ingredients and their type.

We take the initial state or initial ingredients and apply some rules to them.

So we take the initial state and pass them through these rules over and over again until we get a ready to eat rhubarb strawberry pie or whatever.

So in a declarative approach, we have to know how to properly structure these rules.

So the rules we might want to examine our ingredients or state, if mixed, put them in a pan.

With our initial state, that doesn’t match because we haven’t yet mixed our ingredients.

So rule 2 says, if they not mixed then mix them in a bowl. Okay yeah this rule applies.

Now we have a bowl of mixed ingredients as our state.

Now we apply that new state to our rules again.

So rule 1 says if ingredients are mixed place them in a pan, okay yeah now rule 1 does apply, lets do it.

Now we have this new state where the ingredients are mixed and in a pan. Rule 1 is no longer relevant, rule 2 does not apply.

Rule 3 says if the ingredients are in a pan, place them in the oven, great that rule is what applies to this new state, lets do it.

And we end up with a delicious hot apple pie or whatever.

Now, if you are like me, you may be thinking, why are we not still doing imperative programming. This makes sense.

Well, for simple flows yes, but most web applications have more complex flows that cannot be properly captured by imperative programming design.

In a declarative approach, we may have some initial ingredients or initial state like textInput=“”, a single variable.

Maybe text input starts off as an empty string.

We take this initial state and apply it to a set of rules defined in your application.

1. If a user enters text, update text input. Well, right now that doesn’t apply.

2. If template is rendered, calculate the widget.

3. If textInput is updated, re render the template.

Well, none of this applies so the program will just wait around for an event to happen.

So at some point a user updates the text input and then we might apply rule number 1.

We may update that to “abcd”

So we just updated our text and textInput updates, rule number 2 does not apply, rule number 3 says if text input is update, which just occurred, then re render the template and then we go back to rule 2 thats says if template is rendered, calculate the widget, okay lets calculate the widget.

In general, as programmers, we want to strive for more declarative programming designs.

Imperative seems more clear and obvious, but a declarative approach scales very nicely for larger applications.

This is similar to the answer I posted on: Preview a Git push

Drop these functions into your Bash profile:

• gbout - git branch outgoing
• gbin - git branch incoming

You can use this like:

• If on master: gbin branch1 <-- this will show you what's in branch1 and not in master
• If on master: gbout branch1 <-- this will show you what's in master that's not in branch 1

This will work with any branch.

function parse_git_branch {
  git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'
}

function gbin {
    echo branch \($1\) has these commits and \($(parse_git_branch)\) does not
    git log ..$1 --no-merges --format='%h | Author:%an | Date:%ad | %s' --date=local
}

function gbout {
    echo branch \($(parse_git_branch)\) has these commits and \($1\) does not
    git log $1.. --no-merges --format='%h | Author:%an | Date:%ad | %s' --date=local
}

In general, there is no way to know when something on another site has been changed. If the site offers an RSS feed, you should try that. If the site does not offer an RSS feed (or if the RSS feed doesn't include the information you're looking for), then you have to scrape and compare.

I just wanted to share my experience

For me,

$('#selectorId').val()

returned null.

I had to use

$('#selectorId option:selected').val()

I like the SQLite2009 Pro Enterprise Manager suggested by Jfly. However:

• The MySQL datatype INT is not converted to SQlite datatype INTEGER (works with DBeaver )

• It does not import foreign key constaints from MySQL (I could not find any tool that supports the transfer of foreign key constraints from MySQL to SQlite.)

Sorry, but I have to chime in. I have been through several of the suggested solutions, before finding the Prism.Wpf.Interactivity namespace in the Prism project. You can use interaction requests and popup window action to either roll a custom window or for simpler needs there are built in Notification and Confirmation popups. These create true windows and are managed as such. you can pass a context object with any dependencies you need in the dialog. We use this solution at my work since I found it. We have numerous senior devs here and noone has come up with anything better. Our previous solution was the dialog service into an overlay and using a presenter class to make it happen, but you had to have factories for all of the dialog viewmodels, etc.

This isn't trivial but it also isn't super complicated. And it is built in to Prism and is therefore best (or better) practice IMHO.

My 2 cents!

The answer I would provide is that a keystore file is to authenticate yourself to anyone who is asking. It isn't restricted to just signing .apk files, you can use it to store personal certificates, sign data to be transmitted and a whole variety of authentication.

In terms of what you do with it for Android and probably what you're looking for since you mention signing apk's, it is your certificate. You are branding your application with your credentials. You can brand multiple applications with the same key, in fact, it is recommended that you use one certificate to brand multiple applications that you write. It easier to keep track of what applications belong to you.

I'm not sure what you mean by implications. I suppose it means that no one but the holder of your certificate can update your application. That means that if you release it into the wild, lose the cert you used to sign the application, then you cannot release updates so keep that cert safe and backed up if need be.

But apart from signing apks to release into the wild, you can use it to authenticate your device to a server over SSL if you so desire, (also Android related) among other functions.

Introduction

You should use doGet() when you want to intercept on HTTP GET requests. You should use doPost() when you want to intercept on HTTP POST requests. That's all. Do not port the one to the other or vice versa (such as in Netbeans' unfortunate auto-generated processRequest() method). This makes no utter sense.

GET

Usually, HTTP GET requests are idempotent. I.e. you get exactly the same result everytime you execute the request (leaving authorization/authentication and the time-sensitive nature of the page —search results, last news, etc— outside consideration). We can talk about a bookmarkable request. Clicking a link, clicking a bookmark, entering raw URL in browser address bar, etcetera will all fire a HTTP GET request. If a Servlet is listening on the URL in question, then its doGet() method will be called. It's usually used to preprocess a request. I.e. doing some business stuff before presenting the HTML output from a JSP, such as gathering data for display in a table.

@WebServlet("/products")
public class ProductsServlet extends HttpServlet {

    @EJB
    private ProductService productService;

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        List<Product> products = productService.list();
        request.setAttribute("products", products); // Will be available as ${products} in JSP
        request.getRequestDispatcher("/WEB-INF/products.jsp").forward(request, response);
    }

}

Note that the JSP file is explicitly placed in /WEB-INF folder in order to prevent endusers being able to access it directly without invoking the preprocessing servlet (and thus end up getting confused by seeing an empty table).

<table>
    <c:forEach items="${products}" var="product">
        <tr>
            <td>${product.name}</td>
            <td><a href="product?id=${product.id}">detail</a></td>
        </tr>
    </c:forEach>
</table>

Also view/edit detail links as shown in last column above are usually idempotent.

@WebServlet("/product")
public class ProductServlet extends HttpServlet {

    @EJB
    private ProductService productService;

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        Product product = productService.find(request.getParameter("id"));
        request.setAttribute("product", product); // Will be available as ${product} in JSP
        request.getRequestDispatcher("/WEB-INF/product.jsp").forward(request, response);
    }

}

<dl>
    <dt>ID</dt>
    <dd>${product.id}</dd>
    <dt>Name</dt>
    <dd>${product.name}</dd>
    <dt>Description</dt>
    <dd>${product.description}</dd>
    <dt>Price</dt>
    <dd>${product.price}</dd>
    <dt>Image</dt>
    <dd><img src="productImage?id=${product.id}" /></dd>
</dl>

POST

HTTP POST requests are not idempotent. If the enduser has submitted a POST form on an URL beforehand, which hasn't performed a redirect, then the URL is not necessarily bookmarkable. The submitted form data is not reflected in the URL. Copypasting the URL into a new browser window/tab may not necessarily yield exactly the same result as after the form submit. Such an URL is then not bookmarkable. If a Servlet is listening on the URL in question, then its doPost() will be called. It's usually used to postprocess a request. I.e. gathering data from a submitted HTML form and doing some business stuff with it (conversion, validation, saving in DB, etcetera). Finally usually the result is presented as HTML from the forwarded JSP page.

<form action="login" method="post">
    <input type="text" name="username">
    <input type="password" name="password">
    <input type="submit" value="login">
    <span class="error">${error}</span>
</form>

...which can be used in combination with this piece of Servlet:

@WebServlet("/login")
public class LoginServlet extends HttpServlet {

    @EJB
    private UserService userService;

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String username = request.getParameter("username");
        String password = request.getParameter("password");
        User user = userService.find(username, password);

        if (user != null) {
            request.getSession().setAttribute("user", user);
            response.sendRedirect("home");
        }
        else {
            request.setAttribute("error", "Unknown user, please try again");
            request.getRequestDispatcher("/login.jsp").forward(request, response);
        }
    }

}

You see, if the User is found in DB (i.e. username and password are valid), then the User will be put in session scope (i.e. "logged in") and the servlet will redirect to some main page (this example goes to http://example.com/contextname/home), else it will set an error message and forward the request back to the same JSP page so that the message get displayed by ${error}.

You can if necessary also "hide" the login.jsp in /WEB-INF/login.jsp so that the users can only access it by the servlet. This keeps the URL clean http://example.com/contextname/login. All you need to do is to add a doGet() to the servlet like this:

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    request.getRequestDispatcher("/WEB-INF/login.jsp").forward(request, response);
}

(and update the same line in doPost() accordingly)

That said, I am not sure if it is just playing around and shooting in the dark, but the code which you posted doesn't look good (such as using compareTo() instead of equals() and digging in the parameternames instead of just using getParameter() and the id and password seems to be declared as servlet instance variables — which is NOT threadsafe). So I would strongly recommend to learn a bit more about basic Java SE API using the Oracle tutorials (check the chapter "Trails Covering the Basics") and how to use JSP/Servlets the right way using those tutorials.

Update: as per the update of your question (which is pretty major, you should not remove parts of your original question, this would make the answers worthless .. rather add the information in a new block) , it turns out that you're unnecessarily setting form's encoding type to multipart/form-data. This will send the request parameters in a different composition than the (default) application/x-www-form-urlencoded which sends the request parameters as a query string (e.g. name1=value1&name2=value2&name3=value3). You only need multipart/form-data whenever you have a <input type="file"> element in the form to upload files which may be non-character data (binary data). This is not the case in your case, so just remove it and it will work as expected. If you ever need to upload files, then you'll have to set the encoding type so and parse the request body yourself. Usually you use the Apache Commons FileUpload there for, but if you're already on fresh new Servlet 3.0 API, then you can just use builtin facilities starting with HttpServletRequest#getPart(). See also this answer for a concrete example: How to upload files to server using JSP/Servlet?

Similar to what Richard Detsch but with a bit easier to follow (works with packages as well)

Step 1: Unwrap the War file.

jar -xvf MyWar.war

Step 2: move into the directory

cd WEB-INF

Step 3: Run your main with all dependendecies

java -classpath "lib/*:classes/." my.packages.destination.FileToRun

From release version 2.7.9/3.4.3 on, Python by default attempts to perform certificate validation.

This has been proposed in PEP 467, which is worth a read: https://www.python.org/dev/peps/pep-0476/

The changes affect all relevant stdlib modules (urllib/urllib2, http, httplib).

Relevant documentation:

https://docs.python.org/2/library/httplib.html#httplib.HTTPSConnection

This class now performs all the necessary certificate and hostname checks by default. To revert to the previous, unverified, behavior ssl._create_unverified_context() can be passed to the context parameter.

https://docs.python.org/3/library/http.client.html#http.client.HTTPSConnection

Changed in version 3.4.3: This class now performs all the necessary certificate and hostname checks by default. To revert to the previous, unverified, behavior ssl._create_unverified_context() can be passed to the context parameter.

Note that the new built-in verification is based on the system-provided certificate database. Opposed to that, the requests package ships its own certificate bundle. Pros and cons of both approaches are discussed in the Trust database section of PEP 476.

Yes , you can have but its not good idea.

Instead install all these jars to maven repos

There should be no further calls to an object's methods after Dispose has been called on it (although an object should tolerate further calls to Dispose). Therefore the example in the question is silly. If Dispose is called, then the object itself can be discarded. So the user should just discard all references to that whole object (set them to null) and all the related objects internal to it will automatically get cleaned up.

As for the general question about managed/unmanaged and the discussion in other answers, I think any answer to this question has to start with a definition of an unmanaged resource.

What it boils down to is that there is a function you can call to put the system into a state, and there's another function you can call to bring it back out of that state. Now, in the typical example, the first one might be a function that returns a file handle, and the second one might be a call to CloseHandle.

But - and this is the key - they could be any matching pair of functions. One builds up a state, the other tears it down. If the state has been built but not torn down yet, then an instance of the resource exists. You have to arrange for the teardown to happen at the right time - the resource is not managed by the CLR. The only automatically managed resource type is memory. There are two kinds: the GC, and the stack. Value types are managed by the stack (or by hitching a ride inside reference types), and reference types are managed by the GC.

These functions may cause state changes that can be freely interleaved, or may need to be perfectly nested. The state changes may be threadsafe, or they might not.

Look at the example in Justice's question. Changes to the Log file's indentation must be perfectly nested, or it all goes wrong. Also they are unlikely to be threadsafe.

It is possible to hitch a ride with the garbage collector to get your unmanaged resources cleaned up. But only if the state change functions are threadsafe and two states can have lifetimes that overlap in any way. So Justice's example of a resource must NOT have a finalizer! It just wouldn't help anyone.

For those kinds of resources, you can just implement IDisposable, without a finalizer. The finalizer is absolutely optional - it has to be. This is glossed over or not even mentioned in many books.

You then have to use the using statement to have any chance of ensuring that Dispose is called. This is essentially like hitching a ride with the stack (so as finalizer is to the GC, using is to the stack).

The missing part is that you have to manually write Dispose and make it call onto your fields and your base class. C++/CLI programmers don't have to do that. The compiler writes it for them in most cases.

There is an alternative, which I prefer for states that nest perfectly and are not threadsafe (apart from anything else, avoiding IDisposable spares you the problem of having an argument with someone who can't resist adding a finalizer to every class that implements IDisposable).

Instead of writing a class, you write a function. The function accepts a delegate to call back to:

public static void Indented(this Log log, Action action)
{
    log.Indent();
    try
    {
        action();
    }
    finally
    {
        log.Outdent();
    }
}

And then a simple example would be:

Log.Write("Message at the top");
Log.Indented(() =>
{
    Log.Write("And this is indented");

    Log.Indented(() =>
    {
        Log.Write("This is even more indented");
    });
});
Log.Write("Back at the outermost level again");

The lambda being passed in serves as a code block, so it's like you make your own control structure to serve the same purpose as using, except that you no longer have any danger of the caller abusing it. There's no way they can fail to clean up the resource.

This technique is less useful if the resource is the kind that may have overlapping lifetimes, because then you want to be able to build resource A, then resource B, then kill resource A and then later kill resource B. You can't do that if you've forced the user to perfectly nest like this. But then you need to use IDisposable (but still without a finalizer, unless you have implemented threadsafety, which isn't free).

SVN seems to handle binary deltas more efficiently than Git.

I had to decide on a versioning system for documentation (JPEG files, PDF files, and .odt files). I just tested adding a JPEG file and rotating it 90 degrees four times (to check effectiveness of binary deltas). Git's repository grew 400%. SVN's repository grew by only 11%.

So it looks like SVN is much more efficient with binary files.

So my choice is Git for source code and SVN for binary files like documentation.

Since I could not find this answer nowhere:

ES6 way (Modern Browsers)

el.classList.add("foo", "bar", "baz");

you can return void, then you have to mark the method with @ResponseStatus(value = HttpStatus.OK) you don't need @ResponseBody

@RequestMapping(value = "/updateSomeData" method = RequestMethod.POST)
@ResponseStatus(value = HttpStatus.OK)
public void updateDataThatDoesntRequireClientToBeNotified(...) {
    ...
}

Only get methods return a 200 status code implicity, all others you have do one of three things:

• Return void and mark the method with @ResponseStatus(value = HttpStatus.OK)
• Return An object and mark it with @ResponseBody
• Return an HttpEntity instance

You can import a csv file to this website(https://www.tablesgenerator.com/latex_tables) and click copy to clipboard.

Based on your comment to Haim, is this a file on your own server? If so, you need to use the file system path, not url (e.g. file_exists( '/path/to/images/thumbnail.jpg' )).

Here I have written a few steps for How to Get RegID and Notification starting from scratch

1. Create/Register App on Google Cloud
2. Setup Cloud SDK with Development
3. Configure project for GCM
4. Get Device Registration ID
5. Send Push Notifications
6. Receive Push Notifications

You can find a complete tutorial here:

Getting Started with Android Push Notification : Latest Google Cloud Messaging (GCM) - step by step complete tutorial

Code snippet to get Registration ID (Device Token for Push Notification).

Configure project for GCM

Update AndroidManifest file

To enable GCM in our project we need to add a few permissions to our manifest file. Go to AndroidManifest.xml and add this code: Add Permissions

<uses-permission android:name="android.permission.INTERNET”/>
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

<uses-permission android:name="android.permission.VIBRATE" />

<uses-permission android:name=“.permission.RECEIVE" />
<uses-permission android:name=“<your_package_name_here>.permission.C2D_MESSAGE" />
<permission android:name=“<your_package_name_here>.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />

Add GCM Broadcast Receiver declaration in your application tag:

<application
        <receiver
            android:name=".GcmBroadcastReceiver"
            android:permission="com.google.android.c2dm.permission.SEND" ]]>
            <intent-filter]]>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />

Note : please store REGISTRATION_KEY, it is important for sending PN Message to GCM. Also keep in mind: this key will be unique for all devices and GCM will send Push Notifications by REGISTRATION_KEY only.

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

1. PDO stands for PHP Data Object.
2. PDO_MYSQL is the driver that will implement the interface between the dataobject(database) and the user input (a layer under the user interface called "code behind") accessing your data object, the MySQL database.

The purpose of using this is to implement an additional layer of security between the user interface and the database. By using this layer, data can be normalized before being inserted into your data structure. (Capitals are Capitals, no leading or trailing spaces, all dates at properly formed.)

But there are a few nuances to this which you might not be aware of.

First of all, up until now, you've probably written all your queries in something similar to the URL, and you pass the parameters using the URL itself. Using the PDO, all of this is done under the user interface level. User interface hands off the ball to the PDO which carries it down field and plants it into the database for a 7-point TOUCHDOWN.. he gets seven points, because he got it there and did so much more securely than passing information through the URL.

You can also harden your site to SQL injection by using a data-layer. By using this intermediary layer that is the ONLY 'player' who talks to the database itself, I'm sure you can see how this could be much more secure. Interface to datalayer to database, datalayer to database to datalayer to interface.

And:

By implementing best practices while writing your code you will be much happier with the outcome.

If you already have your SSH keys set up and are still getting the password prompt, make sure your repo URL is in the form

git+ssh://[email protected]/username/reponame.git

as opposed to

https://github.com/username/reponame.git

To see your repo URL, run:

git remote show origin

You can change the URL with git remote set-url like so:

git remote set-url origin git+ssh://[email protected]/username/reponame.git

can you try it once...

String dob="your date String";
String dobis=null;
final DateFormat df = new SimpleDateFormat("yyyy-MMM-dd");
final Calendar c = Calendar.getInstance();
try {
    if(dob!=null && !dob.isEmpty() && dob != "")
    {
    c.setTime(df.parse(dob));
    int month=c.get(Calendar.MONTH);
    month=month+1;
    dobis=c.get(Calendar.YEAR)+"-"+month+"-"+c.get(Calendar.DAY_OF_MONTH);
    }

}

You need to use the Thread.sleep() call.

You have a couple of questions here, so I'll address them separately:

I need to store a number of selected items in one field in a database

My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).

You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:

Base table (what you have now):

| id primary_key sequence
| -- other columns here.

Items table:

| id primary_key sequence
| descript VARCHAR(30) UNIQUE

Map table:

| base_id  bigint
| items_id bigint

Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.

And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.

What format should I use store the data?

If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.

What column type should I use store the data?

Personally, I would use TEXT. It does not sound like you'd gain much by making this a BLOB, and TEXT, in my experience, is easier to read if you're using some form of IDE.

I was trying to work on an automated deployment system that runs npm install, so a lot of these solutions wouldn't work for me in an automated fasion. I wasn't in a position to go deleting/re-creating node_modules/ nor could I easily change Node.js versions.

So I ended up running npm shrinkwrap - adding the npm-shrinkwrap.json file to my deployment bundle, and running installs from there. That fixed the problem for me; with the shrinkwrap file as a 'helper', npm seemed to be able to find the right packages and get them installed for me. (Shrinkwrap has other features as well, but this was what I needed it for in this particular case).

Unfortunately none of the answers above worked for me.

I was looking to convert currency numbers from strings like $123,232,122.11 (1232332122.11) or USD 123,122.892 (123122.892) or any currency like ? 98,79,112.50 (9879112.5) to give me a number output including the decimal pointer.

Had to make my own regex which looks something like this:

str = str.match(/\d|\./g).join('');

Add new folder with name of Images in your project. Put some images into Images folder. Then it will work fine.

<input type="image" src="~/Images/Desert.jpg" alt="Submit" width="48" height="48">

I see that there is already an answer about the @return tag, but I want to give more details about it.

First of all, the official JSDoc 3 documentation doesn't give us any examples about the @return for a custom object. Please see https://jsdoc.app/tags-returns.html. Now, let's see what we can do until some standard will appear.

• Function returns object where keys are dynamically generated. Example: {1: 'Pete', 2: 'Mary', 3: 'John'}. Usually, we iterate over this object with the help of for(var key in obj){...}.

  Possible JSDoc according to https://google.github.io/styleguide/javascriptguide.xml#JsTypes

  /**
   * @return {Object.<number, string>}
   */
  function getTmpObject() {
      var result = {}
      for (var i = 10; i >= 0; i--) {
          result[i * 3] = 'someValue' + i;
      }
      return result
  }
  

• Function returns object where keys are known constants. Example: {id: 1, title: 'Hello world', type: 'LEARN', children: {...}}. We can easily access properties of this object: object.id.

  Possible JSDoc according to https://groups.google.com/forum/#!topic/jsdoc-users/TMvUedK9tC4

  • Fake It.

    /**
     * Generate a point.
     *
     * @returns {Object} point - The point generated by the factory.
     * @returns {number} point.x - The x coordinate.
     * @returns {number} point.y - The y coordinate.
     */
    var pointFactory = function (x, y) {
        return {
            x:x,
            y:y
        }
    }
    

  • The Full Monty.

    /**
     @class generatedPoint
     @private
     @type {Object}
     @property {number} x The x coordinate.
     @property {number} y The y coordinate.
     */
    function generatedPoint(x, y) {
        return {
            x:x,
            y:y
        };
    }
    
    /**
     * Generate a point.
     *
     * @returns {generatedPoint} The point generated by the factory.
     */
    
    var pointFactory = function (x, y) {
        return new generatedPoint(x, y);
    }
    

  • Define a type.

    /**
     @typedef generatedPoint
     @type {Object}
     @property {number} x The x coordinate.
     @property {number} y The y coordinate.
     */
    
    
    /**
     * Generate a point.
     *
     * @returns {generatedPoint} The point generated by the factory.
     */
    
    var pointFactory = function (x, y) {
        return {
            x:x,
            y:y
        }
    }
    

  According to https://google.github.io/styleguide/javascriptguide.xml#JsTypes

  • The record type.

    /**
     * @return {{myNum: number, myObject}}
     * An anonymous type with the given type members.
     */
    function getTmpObject() {
        return {
            myNum: 2,
            myObject: 0 || undefined || {}
        }
    }
