Programs & Examples On #App startup

I encountered a similar problem and to overcome it, I implemented the code below in styles, i.e res->values->styles->resource tag 
<item name="android:windowDisablePreview">true</item>

Here is the whole code:

<style name="SplashTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowDisablePreview">true</item>
</style>

I am placing JLBorges's excellent response to a similar question verbatim from cplusplus.com, as it is the most succinct explanation I've read on the subject.

In a template that we write, there are two kinds of names that could be used - dependant names and non- dependant names. A dependant name is a name that depends on a template parameter; a non-dependant name has the same meaning irrespective of what the template parameters are.

For example:

template< typename T > void foo( T& x, std::string str, int count )
{
    // these names are looked up during the second phase
    // when foo is instantiated and the type T is known
    x.size(); // dependant name (non-type)
    T::instance_count ; // dependant name (non-type)
    typename T::iterator i ; // dependant name (type)
      
    // during the first phase, 
    // T::instance_count is treated as a non-type (this is the default)
    // the typename keyword specifies that T::iterator is to be treated as a type.

    // these names are looked up during the first phase
    std::string::size_type s ; // non-dependant name (type)
    std::string::npos ; // non-dependant name (non-type)
    str.empty() ; // non-dependant name (non-type)
    count ; // non-dependant name (non-type)
}

What a dependant name refers to could be something different for each different instantiation of the template. As a consequence, C++ templates are subject to "two-phase name lookup". When a template is initially parsed (before any instantiation takes place) the compiler looks up the non-dependent names. When a particular instantiation of the template takes place, the template parameters are known by then, and the compiler looks up dependent names.

During the first phase, the parser needs to know if a dependant name is the name of a type or the name of a non-type. By default, a dependant name is assumed to be the name of a non-type. The typename keyword before a dependant name specifies that it is the name of a type.

Summary

Use the keyword typename only in template declarations and definitions provided you have a qualified name that refers to a type and depends on a template parameter.

I just ran into the same problem, but I manage to have my query working in SQLite like this:

@shows = Show.order("datetime(date) ASC, attending DESC")

I hope this might help someone save some time

Sorry to revive an old thread, but how about this:

static IEnumerable<T> Merge<T>(params T[][] arrays)
{
    var merged = arrays.SelectMany(arr => arr);

    foreach (var t in merged)
        yield return t;
}

Then in your code:

int[] x={1, 2, 3};
int[] y={4, 5, 6};

var z=Merge(x, y);  // 'z' is IEnumerable<T>

var za=z.ToArray(); // 'za' is int[]

Until you call .ToArray(), .ToList(), or .ToDictionary(...), the memory is not allocated, you are free to "build your query" and either call one of those three to execute it or simply go through them all by using foreach (var i in z){...} clause which returns an item at a time from the yield return t; above...

The above function can be made into an extension as follows:

static IEnumerable<T> Merge<T>(this T[] array1, T[] array2)
{
    var merged = array1.Concat(array2);

    foreach (var t in merged)
        yield return t;
}

So in the code, you can do something like:

int[] x1={1, 2, 3};
int[] x2={4, 5, 6};
int[] x3={7, 8};

var z=x1.Merge(x2).Merge(x3);   // 'z' is IEnumerable<T>

var za=z.ToArray(); // 'za' is int[]

The rest is the same as before.

One other improvement to this would be changing T[] into IEnumerable<T> (so the params T[][] would become params IEnumerable<T>[]) to make these functions accept more than just arrays.

Hope this helps.

Modify your class definition to read like this:

exports.User = function (socket) {
  ...
};

Then rename the file to user.js. Assuming it's in the root directory of your main script, you can include it like this:

var user = require('./user');
var someUser = new user.User();

That's the quick and dirty version. Read about CommonJS Modules if you'd like to learn more.

With literal syntax you can check as follows

static const NSString* kKeyToCheck = @"yourKey"
if (xyz[kKeyToCheck])
  NSLog(@"Key: %@, has Value: %@", kKeyToCheck, xyz[kKeyToCheck]);
else
 NSLog(@"Key pair do not exits for key: %@", kKeyToCheck); 

if you use cast, that is, (int)SomeDouble you will truncate the fractional part. That is, if SomeDouble were 4.9999 the result would be 4, not 5. Converting to int doesn't round the number. If you want rounding use Math.Round

Making Hadley's comment to an answer (hope to make it better visible). Use of apply family without printing is possible with use of the plyr package

x <- 1:2
lapply(x, function(x) x + 1)
#> [[1]]
#> [1] 2
#> 
#> [[2]]
#> [1] 3

plyr::l_ply(x, function(x) x + 1)

This code will work on Calender buttons. size of numbers will increase by using "line-height".

/* Change Size */
<style>
    .ui-datepicker{
        font-size:16px;
        line-height: 1.3;
    }
</style>

If you want to replace a fragment with another, you should have added them dynamically, first of all. Fragments that are hard coded in XML, cannot be replaced.

// Create new fragment and transaction
Fragment newFragment = new ExampleFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();

// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);

// Commit the transaction
transaction.commit();

Refer this post: Replacing a fragment with another fragment inside activity group

Refer1: Replace a fragment programmatically

To do this:

1. open terminal

2. type in the terminal: nano ; which is a text editor available for the terminal. when you do this. something like this would appear.

3. here you can type in your C program

4. type in control(^) + x -> which means to exit.

5. save the file by typing in y to save the file

6. write the file name; e.g. helloStack.c (don't forget to add .c)

7. when this appears, type in gcc helloStack.c

8. then ./a.out: this should give you your result!!

Rather than giving background-size:100%;
We can give background-size:contain;
Check out this for different options avaliable: http://www.css3.info/preview/background-size/

Its as simple as:

var blah = {}; // make a new dictionary (empty)

or

var blah = {key: value, key2: value2}; // make a new dictionary with two pairs 

then

blah.key3 = value3; // add a new key/value pair
blah.key2; // returns value2
blah['key2']; // also returns value2

Angular

var formData = new FormData();
formData.append('key1', 'value1');
formData.append('key2', 'value2');

formData.forEach((value,key) => {
  console.log(key+" "+value)
});

Not: When I am working on Angular 5 (with TypeScript 2.4.2), I tried as above and it works except a static checking error but also for(var pair of formData.entries()) is not working.

var formData = new FormData();
formData.append('key1', 'value1');
formData.append('key2', 'value2');

formData.forEach((value,key) => {
  console.log(key+" "+value)
});

You can simply use:

read.table wants to return a data.frame, which must have an element in each column. Therefore R expects each row to have the same number of elements and it doesn't fill in empty spaces by default. Try read.table("/PathTo/file.csv" , fill = TRUE ) to fill in the blanks.

e.g.

read.table( text= "Element1 Element2
Element5 Element6 Element7" , fill = TRUE , header = FALSE )
#        V1       V2       V3
#1 Element1 Element2         
#2 Element5 Element6 Element7

A note on whether or not to set header = FALSE... read.table tries to automatically determine if you have a header row thus:

header is set to TRUE if and only if the first row contains one fewer field than the number of columns

These are all close to the right answer, but I wouldn't say any solve the problem while remaining most readable to others reading your code. I'd say that answer is a combination of BrenBarn's Answer and tuomasttik's comment below that answer. BrenBarn's answer utilizes isspace builtin, but does not support removing empty strings, as OP requested, and I would tend to attribute that as the standard use case of replacing strings with null.

I rewrote it with .apply, so you can call it on a pd.Series or pd.DataFrame.

Python 3:

To replace empty strings or strings of entirely spaces:

df = df.apply(lambda x: np.nan if isinstance(x, str) and (x.isspace() or not x) else x)

To replace strings of entirely spaces:

df = df.apply(lambda x: np.nan if isinstance(x, str) and x.isspace() else x)

To use this in Python 2, you'll need to replace str with basestring.

Python 2:

To replace empty strings or strings of entirely spaces:

df = df.apply(lambda x: np.nan if isinstance(x, basestring) and (x.isspace() or not x) else x)

To replace strings of entirely spaces:

df = df.apply(lambda x: np.nan if isinstance(x, basestring) and x.isspace() else x)

Convert each character to its ASCII code, subtract the ASCII code for "a" and add 1. I'm deliberately leaving the code as an exercise.

This sounds like homework. If so, please tag it as such.

Also, this won't deal with upper case letters, since you didn't state any requirement to handle them, but if you need to then just lowercase the string before you start.

Oh, and this will only deal with the latin "a" through "z" characters without any accents, etc.

I had a similar use case during testing hibernate event listeners which are only called on commit.

The solution was to wrap the code to be persistent into another method annotated with REQUIRES_NEW. (In another class) This way a new transaction is spawned and a flush/commit is issued once the method returns.

Keep in mind that this might influence all the other tests! So write them accordingly or you need to ensure that you can clean up after the test ran.

You can do it using pandas only:

In [235]:
dfTest = pd.DataFrame({'A':[14.00,90.20,90.95,96.27,91.21],'B':[103.02,107.26,110.35,114.23,114.68], 'C':['big','small','big','small','small']})
df = dfTest[['A', 'B']]
df_norm = (df - df.min()) / (df.max() - df.min())
print df_norm
print pd.concat((df_norm, dfTest.C),1)

          A         B
0  0.000000  0.000000
1  0.926219  0.363636
2  0.935335  0.628645
3  1.000000  0.961407
4  0.938495  1.000000
          A         B      C
0  0.000000  0.000000    big
1  0.926219  0.363636  small
2  0.935335  0.628645    big
3  1.000000  0.961407  small
4  0.938495  1.000000  small

I think using the STL method 'remove_if' from could help to prevent some weird issue when trying to attempt to delete the object that is wrapped by the iterator.

This solution may be less efficient.

Let's say we have some kind of container, like vector or a list called m_bullets:

Bullet::Ptr is a shared_pr<Bullet>

'it' is the iterator that 'remove_if' returns, the third argument is a lambda function that is executed on every element of the container. Because the container contains Bullet::Ptr, the lambda function needs to get that type(or a reference to that type) passed as an argument.

 auto it = std::remove_if(m_bullets.begin(), m_bullets.end(), [](Bullet::Ptr bullet){
    // dead bullets need to be removed from the container
    if (!bullet->isAlive()) {
        // lambda function returns true, thus this element is 'removed'
        return true;
    }
    else{
        // in the other case, that the bullet is still alive and we can do
        // stuff with it, like rendering and what not.
        bullet->render(); // while checking, we do render work at the same time
        // then we could either do another check or directly say that we don't
        // want the bullet to be removed.
        return false;
    }
});
// The interesting part is, that all of those objects were not really
// completely removed, as the space of the deleted objects does still 
// exist and needs to be removed if you do not want to manually fill it later 
// on with any other objects.
// erase dead bullets
m_bullets.erase(it, m_bullets.end());

'remove_if' removes the container where the lambda function returned true and shifts that content to the beginning of the container. The 'it' points to an undefined object that can be considered garbage. Objects from 'it' to m_bullets.end() can be erased, as they occupy memory, but contain garbage, thus the 'erase' method is called on that range.

You can put your custom postgresql.conf in a temporary file inside the container, and overwrite the default configuration at runtime.

To do that :

• Copy your custom postgresql.conf inside your container
• Copy the updateConfig.sh file in /docker-entrypoint-initdb.d/

Dockerfile

FROM postgres:9.6

COPY postgresql.conf      /tmp/postgresql.conf
COPY updateConfig.sh      /docker-entrypoint-initdb.d/_updateConfig.sh

updateConfig.sh

#!/usr/bin/env bash

cat /tmp/postgresql.conf > /var/lib/postgresql/data/postgresql.conf

At runtime, the container will execute the script inside /docker-entrypoint-initdb.d/ and overwrite the default configuration with yout custom one.

If you only want to have glyphicons icons without any additional css you can create a css file and put the code below and include it into main css file.

I have to create this extra file as link below was messing with my site styles too.

//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css

Instead to using it directly I created a css file bootstrap-glyphicons.css

@font-face{font-family:'Glyphicons Halflings';src:url('http://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.eot');src:url('http://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'),url('http://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.woff') format('woff'),url('http://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.ttf') format('truetype'),url('http://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');}.glyphicon{position:relative;top:1px;display:inline-block;font-family:'Glyphicons Halflings';font-style:normal;font-weight:normal;line-height:1;-webkit-font-smoothing:antialiased;}_x000D_

REST

I understand the main idea of REST is extremely simple. We have used web browsers for years and we have seen how easy, flexible, performing, etc web sites are. HTML sites use hyperlinks and forms as the primary means of user interaction. Their main goal is to allow us, clients, to know only those links that we can use in the current state. And REST simply says 'why not use the same principles to drive computer rather than human clients through our application?' Combine this with the power of the WWW infrastructure and you'll get a killer tool for building great distributed applications.

Another possible explanation is for mathematically thinking people. Each application is basically a state machine with business logic actions being state transitions. The idea of REST is to map each transition onto some request to a resource and provide clients with links representing transitions available in the current state. Thus it models the state machine via representations and links. This is why it's called REpresentational State Transfer.

It's quite surprising that all answers seem to focus either on message format, or on HTTP verbs usage. In fact, the message format doesn't matter at all, REST can use any one provided that the service developer documents it. HTTP verbs only make a service a CRUD service, but not yet RESTful. What really turns a service into a REST service are hyperlinks (aka hypermedia controls) embedded into server responses together with data, and their amount must be enough for any client to choose the next action from those links.

Unfortunately, it's rather difficult to find correct info on REST on the Web, except for the Roy Fielding's thesis. (He's the one who derived REST). I would recommend the 'REST in Practice' book as it gives a comprehensive step-by-step tutorial on how to evolve from SOAP to REST.

SOAP

This is one of the possible forms of RPC (remote procedure call) architecture style. In essence, it's just a technology that allows clients call methods of server via service boundaries (network, processes, etc) as if they were calling local methods. Of course, it actually differs from calling local methods in speed, reliability and so on, but the idea is that simple.

Compared

The details like transport protocols, message formats, xsd, wsdl, etc. don't matter when comparing any form of RPC to REST. The main difference is that an RPC service reinvents bicycle by designing it's own application protocol in the RPC API with the semantics that only it knows. Therefore, all clients have to understand this protocol prior to using the service, and no generic infrastructure like caches can be built because of proprietary semantics of all requests. Furthermore, RPC APIs do not suggest what actions are allowed in the current state, this has to be derived from additional documentation. REST on the other hand implies using uniform interfaces to allow various clients to have some understanding of API semantics, and hypermedia controls (links) to highlight available options in each state. Thus, it allows for caching responses to scale services and making correct API usage easily discoverable without additional documentation.

In a way, SOAP (as any other RPC) is an attempt to tunnel through a service boundary treating the connecting media as a black box capable of transmitting messages only. REST is a decision to acknowledge that the Web is a huge distributed information system, to accept the world as is and learn to master it instead of fighting against it.

SOAP seems to be great for internal network APIs, when you control both the server and the clients, and while the interactions are not too complex. It's more natural for developers to use it. However, for a public API that is used by many independent parties, is complex and big, REST should fit better. But this last comparison is very fuzzy.

Update

My experience has unexpectedly shown REST development to be more difficult than SOAP. At least for .NET. While there are great frameworks like ASP.NET Web API, there's no tooling that would automatically generate client-side proxy. Nothing like 'Add Web Service Reference' or 'Add WCF Service Reference'. One has to write all serialization and service querying code by hand. And man, that's lots of boilerplate code. I think REST development needs something similar to WSDL and tooling implementation for each development platform. In fact, there seems to be a good ground: WADL or WSDL 2.0, but neither of the standards seems to be well-supported.

Update (Jan 2016)

Turns out there is now a wide variety of tools for REST API definition. My personal preference is currently RAML.

How Web Services work

Well, this is a too broad question, because it depends on the architecture and technology used in the specific web service. But in general, a web service is simply some application in the Web that can accept requests from clients and return responses. It's exposed to the Web, thus it's a web service, and it's typically available 24/7, that's why it's a service. Of course, it solves some problem (otherwise why would someone ever use a web service) for its clients.

I will like to answer this with numpy, great powerful array computation module in python.

Here is code snippet:

import numpy
a = ['Jellicle', 'Cats', 'are', 'black', 'and', 'white,', 'Jellicle', 'Cats', 
 'are', 'rather', 'small;', 'Jellicle', 'Cats', 'are', 'merry', 'and', 
 'bright,', 'And', 'pleasant', 'to', 'hear', 'when', 'they', 'caterwaul.', 
 'Jellicle', 'Cats', 'have', 'cheerful', 'faces,', 'Jellicle', 'Cats', 
 'have', 'bright', 'black', 'eyes;', 'They', 'like', 'to', 'practise', 
 'their', 'airs', 'and', 'graces', 'And', 'wait', 'for', 'the', 'Jellicle', 
 'Moon', 'to', 'rise.', '']
dict(zip(*numpy.unique(a, return_counts=True)))

Output

{'': 1, 'And': 2, 'Cats': 5, 'Jellicle': 6, 'Moon': 1, 'They': 1, 'airs': 1, 'and': 3, 'are': 3, 'black': 2, 'bright': 1, 'bright,': 1, 'caterwaul.': 1, 'cheerful': 1, 'eyes;': 1, 'faces,': 1, 'for': 1, 'graces': 1, 'have': 2, 'hear': 1, 'like': 1, 'merry': 1, 'pleasant': 1, 'practise': 1, 'rather': 1, 'rise.': 1, 'small;': 1, 'the': 1, 'their': 1, 'they': 1, 'to': 3, 'wait': 1, 'when': 1, 'white,': 1}

Output is in dictionary object in format of (key, value) pairs, where value is count of particular word

This answer is inspire by another answer on stackoverflow, you can view it here

Python boolean keywords are True and False, notice the capital letters. So like this:

a = True;
b = True;
match_var = True if a == b else False
print match_var;

When compiled and run, this prints:

True

i would recommend Modern UI for WPF .

It has a very active maintainer it is awesome and free!

I'm currently porting some projects to MUI, first (and meanwhile second) impression is just wow!

To see MUI in action you could download XAML Spy which is based on MUI.

EDIT: Using Modern UI for WPF a few months and i'm loving it!

Put into a script I like something like that:

#!/bin/bash
set -o xtrace # remove me after debug
TABLE=some_table_name
DB_NAME=prod_database

BASE_DIR=/var/backups/someDir
LOCATION="${BASE_DIR}/myApp_$(date +%Y%m%d_%H%M%S)"
FNAME="${LOCATION}_${DB_NAME}_${TABLE}.sql"

# Create backups directory if not exists
if [[ ! -e $BASE_DIR ]];then
       mkdir $BASE_DIR
       chown -R postgres:postgres $BASE_DIR
fi

sudo -H -u postgres pg_dump --column-inserts --data-only --table=$TABLE $DB_NAME > $FNAME
sudo gzip $FNAME

A few practical facts that might be useful to decide which event to handle (run the script below and focus on the input box):

$('input').on('keyup keydown keypress',e=>console.log(e.type, e.keyCode, e.which, e.key))

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<input/>

Pressing:

• non inserting/typing keys (e.g. Shift, Ctrl) will not trigger a keypress. Press Ctrl and release it:

  keydown 17 17 Control

  keyup 17 17 Control

• keys from keyboards that apply characters transformations to other characters may lead to Dead and duplicate "keys" (e.g. ~, ´) on keydown. Press ´ and release it in order to display a double ´´:

  keydown 192 192 Dead

  keydown 192 192 ´´

  keypress 180 180 ´

  keypress 180 180 ´

  keyup 192 192 Dead

Additionally, non typing inputs (e.g. ranged <input type="range">) will still trigger all keyup, keydown and keypress events according to the pressed keys.

You can just use:

> names(LIST)
[1] "A" "B"

Obviously the names of the first element is just

> names(LIST)[1]
[1] "A"

In MS Windows the temporary directory is set by the environment variable TEMP. In XP, the temporary directory was set per-user as Local Settings\Temp.

If you change your TEMP environment variable to C:\temp, then you get the same when you run :

System.out.println(System.getProperty("java.io.tmpdir"));

Which version of bootstrap are you using? The early versions of Bootstrap 3 (3.0, 3.0.1) didn't work with this functionality.

col-md-offset-0 should be working as seen in this bootstrap example found here (http://getbootstrap.com/css/#grid-responsive-resets):

<div class="row">
   <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
   <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

You want to apply the fixed property to the position style of the element.

position: fixed;

What browser are you working with? Not all browsers support the fixed property. Read more about who supports it, who doesn't and some work around here

http://webreflection.blogspot.com/2009/09/css-position-fixed-solution.html

I don't really understand the meaning of "last version".

As the previous commit can be accessed with HEAD^, I think that you are looking for something like:

git diff HEAD^ HEAD

As of Git 1.8.5, @ is an alias for HEAD, so you can use:

git diff @~..@

The following will also work:

git show

If you want to know the diff between head and any commit you can use:

git diff commit_id HEAD

And this will launch your visual diff tool (if configured):

git difftool HEAD^ HEAD

Since comparison to HEAD is default you can omit it (as pointed out by Orient):

git diff @^
git diff HEAD^
git diff commit_id

Warnings

• @ScottF and @Panzercrisis explain in the comments that on Windows the ~ character must be used instead of ^.

Starting Python 3.8, a .prod function has been included to the math module in the standard library:

math.prod(iterable, *, start=1)

The method returns the product of a start value (default: 1) times an iterable of numbers:

import math
math.prod([1, 2, 3, 4, 5, 6])

>>> 720

If the iterable is empty, this will produce 1 (or the start value, if provided).

Remove the width:100%; declarations.

Block elements should take up the whole available width by default.

Everything in MySQL seems to be done closer to the metal than in MSSQL, And the documentation treats it that way. Especially for optimization, you'll need to understand how indexes, system configuration, and the optimizer interact under various circumstances.

The "optimizer" is more a parser. In MSSQL your query plan is often a surprise (usually good, sometimes not). In MySQL, it pretty much does what you asked it to do, the way you expected it to. Which means you yourself need to have a deep understanding of the various ways it might be done.

Not built around a good TRANSACTION model (default MyISAM engine).

File-system setup is your problem.

All the database configuration is your problem - especially various cache sizes.

Sometimes it seems best to think of it as an ad-hoc, glorified isam. Codd and Date don't carry much weight here. They would say it with no embarrassment.

You can either do 1 of the following:

Change:

SET @UserId = 0 to SELECT @UserId

This will return the value in the same way your 2nd part of the IF statement is.

Or, seeing as @UserId is set as an Output, change:

SELECT SCOPE_IDENTITY() to SET @UserId = SCOPE_IDENTITY()

It depends on how you want to access the data afterwards. If you want the value to be in your result set, use SELECT. If you want to access the new value of the @UserId parameter afterwards, then use SET @UserId

Seeing as you're accepting the 2nd condition as correct, the query you could write (without having to change anything outside of this query) is:

@EmailAddress varchar(200),
@NickName varchar(100),
@Password varchar(150),
@Sex varchar(50),
@Age int,
@EmailUpdates int,
@UserId int OUTPUT
IF 
    (SELECT COUNT(UserId) FROM RegUsers WHERE EmailAddress = @EmailAddress) > 0
    BEGIN
        SELECT 0
    END
ELSE
    BEGIN
        INSERT INTO RegUsers (EmailAddress,NickName,PassWord,Sex,Age,EmailUpdates) VALUES (@EmailAddress,@NickName,@Password,@Sex,@Age,@EmailUpdates)
        SELECT SCOPE_IDENTITY()
    END

END

John's answer won't produce .txt files as the OP wants. Use:

Not an actual answer but more as a reference.

If you are using the jaxws Maven plugin and you get the same error message, add the mentioned property to the plugin configuration:

...
<plugin>
  <groupId>org.jvnet.jax-ws-commons</groupId>
  <artifactId>jaxws-maven-plugin</artifactId>
  <version>2.3</version>
  <configuration>
    <!-- Needed with JAXP 1.5 -->
    <vmArgs>
        <vmArg>-Djavax.xml.accessExternalSchema=all</vmArg>
    </vmArgs>
  </configuration>
</plugin>

Something like this..

 RelativeLayout linearLayout = (RelativeLayout) findViewById(R.id.widget43);
                // ListView listView = (ListView) findViewById(R.id.ListView01);

                LayoutInflater inflater = (LayoutInflater) this
                        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                // View footer = inflater.inflate(R.layout.footer, null);
                View footer = LayoutInflater.from(this).inflate(R.layout.footer,
                        null);
                final RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
                        RelativeLayout.LayoutParams.FILL_PARENT,
                        RelativeLayout.LayoutParams.FILL_PARENT);
                layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 1);
footer.setLayoutParams(layoutParams);

Use "$@" (works for all POSIX compatibles).

[...] , bash features the "$@" variable, which expands to all command-line parameters separated by spaces.

From Bash by example.

As of Bootstrap 3.x, there's an example of this in the docs here: http://getbootstrap.com/components/#input-groups-buttons-dropdowns

<div class="input-group">
  <input type="text" class="form-control" aria-label="...">
  <div class="input-group-btn">
    <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Action <span class="caret"></span></button>
    <ul class="dropdown-menu dropdown-menu-right" role="menu">
      <li><a href="#">Action</a></li>
      <li><a href="#">Another action</a></li>
      <li><a href="#">Something else here</a></li>
      <li class="divider"></li>
      <li><a href="#">Separated link</a></li>
    </ul>
  </div><!-- /btn-group -->
</div><!-- /input-group -->

If date and col_date are the same columns you should simply do:

SELECT A, MAX(date) FROM t GROUP BY A

Why not use:

WITH x AS ( SELECT A, MAX(col_date) m FROM TABLENAME )
SELECT A, date FROM TABLENAME t JOIN x ON x.A = t.A AND x.m = t.col_date

Otherwise:

SELECT A, FIRST_VALUE(date) KEEP(dense_rank FIRST ORDER BY col_date DESC)
  FROM TABLENAME
 GROUP BY A

We can do this using data() method. C++11 provides this method.

Code Snippet

#include<bits/stdc++.h>
using namespace std;


int main()
{
  ios::sync_with_stdio(false);

  vector<int>v = {7, 8, 9, 10, 11};
  int *arr = v.data();

  for(int i=0; i<v.size(); i++)
  {
    cout<<arr[i]<<" ";
  }

  return 0;
}

Alternatively you can write the same like

{
    test: /\.(svg|png|jpg|jpeg|gif)$/,
    include: 'path of input image directory',
    use: {
        loader: 'file-loader',
        options: {
            name: '[path][name].[ext]',
            outputPath: 'path of output image directory'
        }
    }
}

and then use simple import

import varName from 'relative path';

and in jsx write like <img src={varName} ..../>

.... are for other image attributes

I recommend against using the jQuery code that was accepted as the answer. While it does not insert the string to decode into the page, it does cause things such as scripts and HTML elements to get created. This is way more code than we need. Instead, I suggest using a safer, more optimized function.

var decodeEntities = (function() {
  // this prevents any overhead from creating the object each time
  var element = document.createElement('div');

  function decodeHTMLEntities (str) {
    if(str && typeof str === 'string') {
      // strip script/html tags
      str = str.replace(/<script[^>]*>([\S\s]*?)<\/script>/gmi, '');
      str = str.replace(/<\/?\w(?:[^"'>]|"[^"]*"|'[^']*')*>/gmi, '');
      element.innerHTML = str;
      str = element.textContent;
      element.textContent = '';
    }

    return str;
  }

  return decodeHTMLEntities;
})();

http://jsfiddle.net/LYteC/4/

To use this function, just call decodeEntities("&") and it will use the same underlying techniques as the jQuery version will—but without jQuery's overhead, and after sanitizing the HTML tags in the input. See Mike Samuel's comment on the accepted answer for how to filter out HTML tags.

This function can be easily used as a jQuery plugin by adding the following line in your project.

jQuery.decodeEntities = decodeEntities;

Yes, but the syntax is different than what you have

SELECT
    <fields>
FROM
    <table1>
    LEFT JOIN <table2>
        ON <criteria for join>
        AND <other criteria for join>
    LEFT JOIN <table3> 
        ON <criteria for join>
        AND <other criteria for join>

(1) SQLite has a built in rowid pseudo-column so this works:

sqldf("select min(rowid) rowid, id, string 
               from test 
               group by id")

giving:

  rowid id string
1     1  1      A
2     3  2      B
3     5  3      C
4     7  4      D
5     9  5      E

(2) Also sqldf itself has a row.names= argument:

sqldf("select min(cast(row_names as real)) row_names, id, string 
              from test 
              group by id", row.names = TRUE)

giving:

  id string
1  1      A
3  2      B
5  3      C
7  4      D
9  5      E

(3) A third alternative which mixes the elements of the above two might be even better:

sqldf("select min(rowid) row_names, id, string 
               from test 
               group by id", row.names = TRUE)

giving:

  id string
1  1      A
3  2      B
5  3      C
7  4      D
9  5      E

Note that all three of these rely on a SQLite extension to SQL where the use of min or max is guaranteed to result in the other columns being chosen from the same row. (In other SQL-based databases that may not be guaranteed.)

No, those are nested dictionaries, so that is the only real way (you could use get() but it's the same thing in essence). However, there is an alternative. Instead of having nested dictionaries, you can use a tuple as a key instead:

tempDict = {("ONE", "TWO", "THREE"): 10}
tempDict["ONE", "TWO", "THREE"]

This does have a disadvantage, there is no (easy and fast) way of getting all of the elements of "TWO" for example, but if that doesn't matter, this could be a good solution.

To make the client code (from tolomea) work on Solaris you need to pass the ttl value for the IP_MULTICAST_TTL socket option as an unsigned char. Otherwise you will get an error. This worked for me on Solaris 10 and 11:

import socket
import struct

MCAST_GRP = '224.1.1.1'
MCAST_PORT = 5007
ttl = struct.pack('B', 2)

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)

For those using Xamarin, I had to add the key NSLocationWhenInUseUsageDescription to the info.plist manually since it was not available in the dropdowns in either Xamarin 5.5.3 Build 6 or XCode 6.1 - only NSLocationUsageDescription was in the list, and that caused the CLLocationManager to continue to fail silently.

Use the SingleOrDefault() instead of FirstOrDefault().

This is the shortest version I could find,saving/hiding an extra conversion:

pil_image = PIL.Image.open('image.jpg')
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)

If reading a file from a URL:

import cStringIO
import urllib
file = cStringIO.StringIO(urllib.urlopen(r'http://stackoverflow.com/a_nice_image.jpg').read())
pil_image = PIL.Image.open(file)
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)

this.dataSource = new MatTableDataSource<Element>(this.elements);

Add this line below your action of add or delete the particular row.

refresh() {
  this.authService.getAuthenticatedUser().subscribe((res) => {
    this.user = new MatTableDataSource<Element>(res);   
  });
}

You want to use:

git checkout --ours foo/bar.java
git add foo/bar.java

If you rebase a branch feature_x against main (i.e. running git rebase main while on branch feature_x), during rebasing ours refers to main and theirs to feature_x.

As pointed out in the git-rebase docs:

Note that a rebase merge works by replaying each commit from the working branch on top of the branch. Because of this, when a merge conflict happens, the side reported as ours is the so-far rebased series, starting with <upstream>, and theirs is the working branch. In other words, the sides are swapped.

For further details read this thread.

This might be like resurrecting a dead horse. But just so it's out there, the reason why the answer to these types of questions to simply put dll's into the system32 folder is because that folder is in the os's system path.

It's actually best practice to provide the os with a path link.

With windows 10

1. open up file explorer
2. right click on "this pc" and select "properties"
3. Now in the "Control Panel\System and Security\System" window that comes up, click on "Advanced System Settings" from the left hand panel.
4. At the bottom of the next window, click on the "Environment Variables" button.
5. On the next window, there are two panels, the top one is for modifying variables to the current user, and the bottom panel is for modifying variables to the system. On the bottom panel, find the variable "Path" and click it to select it, then click on the "edit" button.
6. Here you can then create, edit, delete, or update the different paths for the system. For example, to add mingw32-make to the system so you can access that command via command prompt, click new, then paste in the path to the bin. Example path, "D:\Qt\Tools\mingw730_64\bin", no quotation marks nor additional whitespaces.
7. Click ok on all the windows so that the changes are saved, then reboot your computer for the changes to be loaded.

As a follow on, you could select "all nodes with a particular attribute" like this:

//*[@id='4']

try this:

         TextView calloutContent = new TextView(getApplicationContext());
         calloutContent.setTextColor(Color.BLACK);
         calloutContent.setSingleLine(false);
         calloutContent.setLines(2);
         calloutContent.setText(" line 1" + System.getProperty ("line.separator")+"  line2" );

My test string for the following:

testing='12345,abc,123,54321,ab15234,123456,52341';

If I understand your question, you'd want ["12345", "54321", "15234", "52341"].

If JS engines supported regexp lookbehinds, you could do:

testing.match(/(?<!\d)\d{5}(?!\d)/g)

Since it doesn't currently, you could:

testing.match(/(?:^|\D)(\d{5})(?!\d)/g)

and remove the leading non-digit from appropriate results, or:

pentadigit=/(?:^|\D)(\d{5})(?!\d)/g;
result = [];
while (( match = pentadigit.exec(testing) )) {
    result.push(match[1]);
}

Note that for IE, it seems you need to use a RegExp stored in a variable rather than a literal regexp in the while loop, otherwise you'll get an infinite loop.

I came across with the same issue. But I believe , handling null in the sql is not a good option. such things should be handled in java program for better performance. secondly , rs.getString("column") != NULL is also not a good option as you are comparing string's reference not value. better to use .equals() method while checking null or isEmpty() method. Again, with this you can use null check, that is fine.

Just call comboBox.updateUI() after doing comboBox.setSelectedItem or comboBox.setSelectedIndex or comboModel.setSelectedItem

The example for switch statement shows that you can't stack non-empty cases, but should use gotos:

// statements_switch.cs
using System;
class SwitchTest 
{
   public static void Main()  
   {
      Console.WriteLine("Coffee sizes: 1=Small 2=Medium 3=Large"); 
      Console.Write("Please enter your selection: "); 
      string s = Console.ReadLine(); 
      int n = int.Parse(s);
      int cost = 0;
      switch(n)       
      {         
         case 1:   
            cost += 25;
            break;                  
         case 2:            
            cost += 25;
            goto case 1;           
         case 3:            
            cost += 50;
            goto case 1;             
         default:            
            Console.WriteLine("Invalid selection. Please select 1, 2, or3.");            
            break;      
       }
       if (cost != 0)
          Console.WriteLine("Please insert {0} cents.", cost);
       Console.WriteLine("Thank you for your business.");
   }
}

dont do this

number = (number < 0 ? -number : number);

or

if (number < 0) number = -number;

this will be an bug when you run find bug on your code it will report it as RV_NEGATING_RESULT_OF

You can use DDC (Domain Directory Controller). It is a new, easy to use, Java SDK. You don't even need to know LDAP to use it. It exposes an object-oriented API instead.

You can find it here.

You get the cursor position by calling GetCursorPos.

POINT p;
if (GetCursorPos(&p))
{
    //cursor position now in p.x and p.y
}

This returns the cursor position relative to screen coordinates. Call ScreenToClient to map to window coordinates.

if (ScreenToClient(hwnd, &p))
{
    //p.x and p.y are now relative to hwnd's client area
}

You hide and show the cursor with ShowCursor.

ShowCursor(FALSE);//hides the cursor
ShowCursor(TRUE);//shows it again

You must ensure that every call to hide the cursor is matched by one that shows it again.

I have a little generic "no keyboard" script - works for me with Android and iPhone:

  $('.readonlyJim').on('focus', function () {
      $(this).trigger('blur')
  })

Simply attach add class readonlyJim to the input tag and voila.

(*Sorry too much StarTrek here)

This is because the inner div has 100% of the opacity of the div it is nested in (which has 40% opacity).

In order to circumvent it, there are a few things you could do.

You could create two separate divs like so:

<div id="background"></div>
<div id="bContent"></div>

Set your desired CSS opacity and other properties for the background and use the z-index property (z-index) to style and position the bContent div. With this you can place the div overtope of the background div without having it's opacity mucked with.

Another option is to RGBa. This will allow you to nest your divs and still achieve div specific opacity.

The last option is to simply make a semi transparent .png image of the color you want in your desired image editor of choice, set the background-image property to the URL of the image and then you won't have to worry about mucking about with the CSS and losing the capability and organization of a nested div structure.

We did it like this:

from p in Products                         
join bp in BaseProducts on p.BaseProductId equals bp.Id                    
where !string.IsNullOrEmpty(p.SomeId) && p.LastPublished >= lastDate                         
group new { p, bp } by new { p.SomeId } into pg    
let firstproductgroup = pg.FirstOrDefault()
let product = firstproductgroup.p
let baseproduct = firstproductgroup.bp
let minprice = pg.Min(m => m.p.Price)
let maxprice = pg.Max(m => m.p.Price)
select new ProductPriceMinMax
{
SomeId = product.SomeId,
BaseProductName = baseproduct.Name,
CountryCode = product.CountryCode,
MinPrice = minprice, 
MaxPrice = maxprice
};

EDIT: we used the version of AakashM, because it has better performance

The "delete module-info.java at your Project Explorer tab" answer is the easiest and most straightforward answer, but

for those who would want a little more understanding or control of what's happening, the following alternate methods may be desirable;

• make an ever so slightly more realistic application; com.YourCompany.etc or just com.HelloWorld (Project name: com.HelloWorld and class name: HelloWorld)

or

• when creating the java project; when in the Create Java Project dialog, don't choose Finish but Next, and deselect Create module-info.java file

Yes, just add multiple FileAppenders to your logger. For example:

<log4net>
    <appender name="File1Appender" type="log4net.Appender.FileAppender">
        <file value="log-file-1.txt" />
        <appendToFile value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date %message%newline" />
        </layout>
    </appender>
    <appender name="File2Appender" type="log4net.Appender.FileAppender">
        <file value="log-file-2.txt" />
        <appendToFile value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date %message%newline" />
        </layout>
    </appender>

    <root>
        <level value="DEBUG" />
        <appender-ref ref="File1Appender" />
        <appender-ref ref="File2Appender" />
    </root>
</log4net>

@Transactional annotation on controller is missing

If you want work on currencies, you have to use BigDecimal class. The problem is, there's no way to store some float numbers in memory (eg. you can store 5.3456, but not 5.3455), which can effects in bad calculations.

There's an nice article how to cooperate with BigDecimal and currencies:

http://www.javaworld.com/javaworld/jw-06-2001/jw-0601-cents.html

You can also try this to determine the current global sql_mode value:

SELECT @@GLOBAL.sql_mode;

or session sql_mode value:

SELECT @@SESSION.sql_mode;

I also had the feeling that the SQL mode was indeed empty.

If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40).

If you use pyplot programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40) or afterwards with ax.yaxis.label.set_size(40).

There is packaging package available, which will allow you to compare versions as per PEP-440, as well as legacy versions.

>>> from packaging.version import Version, LegacyVersion
>>> Version('1.1') < Version('1.2')
True
>>> Version('1.2.dev4+deadbeef') < Version('1.2')
True
>>> Version('1.2.8.5') <= Version('1.2')
False
>>> Version('1.2.8.5') <= Version('1.2.8.6')
True

Legacy version support:

>>> LegacyVersion('1.2.8.5-5-gdeadbeef')
<LegacyVersion('1.2.8.5-5-gdeadbeef')>

Comparing legacy version with PEP-440 version.

>>> LegacyVersion('1.2.8.5-5-gdeadbeef') < Version('1.2.8.6')
True

You can use Pandas library to read the first few lines from the huge dataset.

import pandas as pd

data = pd.read_csv("names.csv", nrows=1)

You can mention the number of lines to be read in the nrows parameter.

A server socket listens on a single port. All established client connections on that server are associated with that same listening port on the server side of the connection. An established connection is uniquely identified by the combination of client-side and server-side IP/Port pairs. Multiple connections on the same server can share the same server-side IP/Port pair as long as they are associated with different client-side IP/Port pairs, and the server would be able to handle as many clients as available system resources allow it to.

On the client-side, it is common practice for new outbound connections to use a random client-side port, in which case it is possible to run out of available ports if you make a lot of connections in a short amount of time.

I use Angular and i set the default option by

HTML Template

<select #selectConnection [(ngModel)]="selectedVal" class="form-control  col-sm-6 "  max-width="100px"   title="Select" 
      data-size="10"> 
        <option  >test1</option>
        <option >test2</option>      
      </select>

Script:

sselectedVal:any="test1";

Date is best for storing a date object. It is the persisted one, the Serialized one ...

Calendar is best for manipulating Dates.

Note: we also sometimes favor java.lang.Long over Date, because Date is mutable and therefore not thread-safe. On a Date object, use setTime() and getTime() to switch between the two. For example, a constant Date in the application (examples: the zero 1970/01/01, or an applicative END_OF_TIME that you set to 2099/12/31 ; those are very useful to replace null values as start time and end time, especially when you persist them in the database, as SQL is so peculiar with nulls).

If you want to find the first day and last day from the specified date variable then you can do this like below:

$date    =    '2012-02-12';//your given date

$first_date_find = strtotime(date("Y-m-d", strtotime($date)) . ", first day of this month");
echo $first_date = date("Y-m-d",$first_date_find);

$last_date_find = strtotime(date("Y-m-d", strtotime($date)) . ", last day of this month");
echo $last_date = date("Y-m-d",$last_date_find);

For the current date just simple use this

$first_date = date('Y-m-d',strtotime('first day of this month'));
$last_date = date('Y-m-d',strtotime('last day of this month'));

You can use negated character classes to exclude certain characters: for example [^abcde] will match anything but a,b,c,d,e characters.

Instead of specifying all the characters literally, you can use shorthands inside character classes: [\w] (lowercase) will match any "word character" (letter, numbers and underscore), [\W] (uppercase) will match anything but word characters; similarly, [\d] will match the 0-9 digits while [\D] matches anything but the 0-9 digits, and so on.

If you use PHP you can take a look at the regex character classes documentation.

In this code, for permanent and intense search , have memory or process for use, and I select memory, with converter array as index. I hope it's helpful

public enum Test{ 
VALUE_ONE(101, "Im value one"),
VALUE_TWO(215, "Im value two");
private final int number;
private final byte[] desc;

private final static int[] converter = new int[216];
static{
    Test[] st = values();
    for(int i=0;i<st.length;i++){
        cv[st[i].number]=i;
    }
}

Test(int value, byte[] description) {
    this.number = value;
    this.desc = description;
}   
public int value() {
    return this.number;
}
public byte[] description(){
    return this.desc;
}

public static String description(int value) {
    return values()[converter[rps]].desc;
}

public static Test fromValue(int value){
return values()[converter[rps]];
}
}

So I figured out what is wrong with this statement:

Import-Csv H:\Programs\scripts\SomeText.csv |`

(Original)

Import-Csv H:\Programs\scripts\SomeText.csv -Delimiter "|"

(Proposed, You must use quotations; otherwise, it will not work and ISE will give you an error)

It requires the -Delimiter "|", in order for the variable to be populated with an array of items. Otherwise, Powershell ISE does not display the list of items.

I cannot say that I would recommend the | operator, since it is used to pipe cmdlets into one another.

I still cannot get the if statement to return true and output the values entered via the prompt.

If anyone else can help, it would be great. I still appreciate the post, it has been very helpful!

Configuring JDKs

1. Windows -> Preferences -> Installed JREs, to configured the installed JDKs
2. Project Properties, Java Compiler, Enable project specific settings (or configure Workspace settings), JDK Compliance
3. Project Properties, Java Build Path, Libraries, Add Library, JRE system library, Workspace default or Alternate JRE (one of the JREs configured in

Maven

BUT IF you are using maven, provided that you have your latest JRE (Windows/Preferences/Installed JREs) -for example JDK 1.8

You can select the level 1.6, 1.7, 1.8 by configuring the maven-compiler-plugin source and target attributes, like this

            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.3</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>

And ideally, if you have a parent pom, you can do it for all the modules (Eclipse projects) in the parent pom, in one single place.

Source and Target If we want to use the Java 8 language features the –source should be set to 1.8. Also, for the compiled classes to be compatible with JVM 1.8, the –target value should be 1.8.

Updating JRE library that is broken in many projects at once (with Maven)

Rather than updating one by one the JRE library, let Maven do it for you.

Selecting the projects and right-clicking for Maven -> Update Project, will set the system library to the path of the installed JDK, in case the paths are broken (because you installed a new JDK or imported from another computer, etc.) and set the JDK compliance according to the maven source and target setting in the pom.

CARL LANGE also showed how to get hidden, autoplaying audio in html5 on a iOS device. Works for me.

In HTML,

<div id="hideme">
    <audio id="audioTag" controls>
        <source src="/path/to/audio.mp3">
    </audio>
</div>

with JS

<script type="text/javascript">
window.onload = function() {
    var audioEl = document.getElementById("audioTag");
    audioEl.load();
    audioEl.play();
};
</script>

In CSS,

#hideme {display: none;}

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none): << enter root here >>

i enter root as current password

OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

and do the rest

You can fix this issue without opening the storyboard as a source. This warning is triggered by UILabels if numberOfLines !=1 and deployment target is < 8.0

HOW TO FIND IT?

1. Go to Issue Navigator (CMD+8) and Select latest built with the warning
2. Locate the warning(s) (search for "Automatic Preferred Max Layout") and press expand button on the right
   
3. Find the Object ID of the UILabel
4. Open the Storyboard and SEARCH (CMD+f) for the object. It will SELECT AND HIGHLIGHT the UILabel
5. Set Preferred Width = 0 "Explicit" as others suggested

If the types of the parameters are all the same (varchar2 for example), you can have a package like this which will do the following:

CREATE OR REPLACE PACKAGE testuser.test_pkg IS

   TYPE assoc_array_varchar2_t IS TABLE OF VARCHAR2(4000) INDEX BY BINARY_INTEGER;

   PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t);

END test_pkg;

CREATE OR REPLACE PACKAGE BODY testuser.test_pkg IS

   PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t) AS
   BEGIN
      FOR i IN p_parm.first .. p_parm.last
      LOOP
         dbms_output.put_line(p_parm(i));
      END LOOP;

   END;

END test_pkg;

Then, to call it you'd need to set up the array and pass it:

DECLARE
  l_array testuser.test_pkg.assoc_array_varchar2_t;
BEGIN
  l_array(0) := 'hello';
  l_array(1) := 'there';  

  testuser.test_pkg.your_proc(l_array);
END;
/

You need to install the Visual C++ libraries: http://www.microsoft.com/en-us/download/details.aspx?id=30679

I would like to share my way of starting chrome - specificaly youtube tv - in full screen mode automatically, without the need of pressing F11. kiosk/fullscreen options doesn't seem to work (Version 41.0.2272.89). It has some steps though...

• Start chrome and navigate to page (www.youtube.com/tv)
• Drag the address from the address bar (the lock icon) to the desktop. It will create a shortcut.
• From chrome, open Apps (the icon with the multiple coloured dots)
• From desktop, drag the shortcut into the Apps space
• Right click on the new icon in Apps and select "Open fullscreen"
• Right click again on the icon in Apps and select "Create shortcuts..."
• Select for example Desktop and Create. A new shortcut will be created on desktop.

Now, whenever you click on this shortcut, chrome will start in fullscreen and at the page you defined. I guess you can put this shortcut in startup folder to run when windows starts, but I haven't tried it.

SELECT * FROM table ORDER BY id DESC LIMIT 50

save resources make one query, there is no need to make nested queries

You can use the dynamic object ViewBag to pass data from Controllers to Views.

Add the following to your controller:

ViewBag.MyList = myList;

Then you can acces it from your view:

@ViewBag.MyList

// e.g.
@foreach (var item in ViewBag.MyList) { ... }

we can simply use:

public void animStart(View view) {
    if(count==0){
        Log.d("count", String.valueOf(count));
        i1.animate().alpha(0f).setDuration(2000);
        i2.animate().alpha(1f).setDuration(2000);
        count =1;
    }
    else if(count==1){
        Log.d("count", String.valueOf(count));
        count =0;
        i2.animate().alpha(0f).setDuration(2000);
        i1.animate().alpha(1f).setDuration(2000);
    }
}

where i1 and i2 are defined in the onCreateView() as:

    i1 = (ImageView)findViewById(R.id.firstImage);
    i2 = (ImageView)findViewById(R.id.secondImage);

count is a class variable initilaized to 0.

The XML file is :

@drawable/first and @drawable/second are the images in the drawable folder in res.

For anyone who is searching for a solution about posting to Instagram using AWS lambda and puppeteer (chrome-aws-lambda). Noted that this solution allow you to post 1 photo for each post only. If you are not using lambda, just replace chrome-aws-lambda with puppeteer.

For the first launch of lambda, it is normal that will not work because instagram detects “Suspicious login attempt”. Just goto instagram page using your PC and approve it, everything should be fine.

Here's my code, feel free to optimize it:

// instagram.js
const chromium = require('chrome-aws-lambda');

const username = process.env.IG_USERNAME;
const password = process.env.IG_PASSWORD;

module.exports.post = async function(fileToUpload, caption){
    const browser = await chromium.puppeteer.launch({
        args: [...chromium.args, '--window-size=520,700'],
        defaultViewport: chromium.defaultViewport,
        executablePath: await chromium.executablePath,
        headless: false,
        ignoreHTTPSErrors: true,

Just ps -o etime= -p "<your_process_pid>"

Truncating .TotalSeconds is important since it's defined as the value of the current System.TimeSpan structure expressed in whole fractional seconds.

And how about an extension for DateTime? The second one is probably more confusing that it's worth until property extensions exist.

/// <summary>
/// Converts a given DateTime into a Unix timestamp
/// </summary>
/// <param name="value">Any DateTime</param>
/// <returns>The given DateTime in Unix timestamp format</returns>
public static int ToUnixTimestamp(this DateTime value)
{
    return (int)Math.Truncate((value.ToUniversalTime().Subtract(new DateTime(1970, 1, 1))).TotalSeconds);
}

/// <summary>
/// Gets a Unix timestamp representing the current moment
/// </summary>
/// <param name="ignored">Parameter ignored</param>
/// <returns>Now expressed as a Unix timestamp</returns>
public static int UnixTimestamp(this DateTime ignored)
{
    return (int)Math.Truncate((DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds);
}

I don't think there's any one right answer to this question, but my advice would be to stick with SWT unless you are encountering severe limitations that require such a massive overhaul.

Also, SWT is actually newer and more actively maintained than Swing. (It was originally developed as a replacement for Swing using native components).

At my work, we have a very big system that runs on many PCs at the same time, with very big tables with hundreds of thousands of rows, and sometimes many millions of rows.

When you make a SELECT on a very big table, let's say you want to know every transaction a user has made in the past 10 years, and the primary key of the table is not built in an efficient way, the query might take several minutes to run.

Then, our application might me running on many user's PCs at the same time, accessing the same database. So if someone tries to insert into the table that the other SELECT is reading (in pages that SQL is trying to read), then a LOCK can occur and the two transactions block each other.

We had to add a "NO LOCK" to our SELECT statement, because it was a huge SELECT on a table that is used a lot by a lot of users at the same time and we had LOCKS all the time.

I don't know if my example is clear enough? This is a real life example.

This is a small program that will keep asking an input until required input is given.

we should keep the required number as a string, otherwise it may not work. input is taken as string by default

required_number = '18'

while True:
    number = input("Enter the number\n")
    if number == required_number:
        print ("GOT IT")
        break
    else:
        print ("Wrong number try again")

or you can use eval(input()) method

required_number = 18

while True:
    number = eval(input("Enter the number\n"))
    if number == required_number:
        print ("GOT IT")
        break
    else:
        print ("Wrong number try again")

there is another technique

use

background-size:cover

That is it full set of css is

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

Latest browsers support the default property.

In my case it a simple issue. I have uploaded an app in the console before so i try re uploading it after resolving some issues All i do is delete the previous APK from the Artifact Library

For SQL Server

sp_help tablename

A more generic answer that would have saved me time, and hopefully others:

Does not work (returns count of all rows):

DB::table('users')
            ->select('first_name')
            ->distinct()
            ->count();

The fix:

DB::table('users')
            ->distinct()
            ->count('first_name');

You can use a StringWriter to write values to a string. It provides a stream-like syntax (though does not derive from Stream) which works with an underlying StringBuilder.

A simple solution is to search in all files. Type in "*" while using wildcards. Which would match all lines. At the end of the find results window you should see a line of the sort:

Matching lines: 563 Matching files: 17 Total files searched: 17

Of course this is not very good for large projects, since all lines are mached and loaded into memory to be dispayed at the find results window.

Reference:

• Advanced Example

Best practice: one form per product is definitely the way to go.

Benefits:

• It will save you the hassle of having to parse the data to figure out which product was clicked
• It will reduce the size of data being posted

In your specific situation

If you only ever intend to have one form element, in this case a submit button, one form for all should work just fine.

My recommendation Do one form per product, and change your markup to something like:

<form method="post" action="">
    <input type="hidden" name="product_id" value="123">
    <button type="submit" name="action" value="add_to_cart">Add to Cart</button>
</form>

This will give you a much cleaner and usable POST. No parsing. And it will allow you to add more parameters in the future (size, color, quantity, etc).

Note: There's no technical benefit to using <button> vs. <input>, but as a programmer I find it cooler to work with action=='add_to_cart' than action=='Add to Cart'. Besides, I hate mixing presentation with logic. If one day you decide that it makes more sense for the button to say "Add" or if you want to use different languages, you could do so freely without having to worry about your back-end code.

def nested1(num1): 
    print "nested1 has",num1
    def nested2(num2):
        print "nested2 has",num2,"and it can reach to",num1
        return num1+num2    #num1 referenced for reading here
    return nested2

Gives:

In [17]: my_func=nested1(8)
nested1 has 8

In [21]: my_func(5)
nested2 has 5 and it can reach to 8
Out[21]: 13

This is an example of what a closure is and how it can be used.

To start the PostgreSQL server:

pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

To end the PostgreSQL server:

pg_ctl -D /usr/local/var/postgres stop -s -m fast

You can also create an alias via CLI to make it easier:

alias pg-start='pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start'
alias pg-stop='pg_ctl -D /usr/local/var/postgres stop -s -m fast'

With these you can just type "pg-start" to start PostgreSQL and "pg-stop" to shut it down.

Use the random module: http://docs.python.org/library/random.html

import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)

This samples the two values without replacement (so the two values are different).

The default generator for Windows seems to be set to NMAKE. Try to use:

cmake -G "MinGW Makefiles"

Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.

Shortest form (without having to install random libraries) ?

public static void play(String filename)
{
    try
    {
        Clip clip = AudioSystem.getClip();
        clip.open(AudioSystem.getAudioInputStream(new File(filename)));
        clip.start();
    }
    catch (Exception exc)
    {
        exc.printStackTrace(System.out);
    }
}

The only problem is there is no good way to make this method blocking to close and dispose the data after *.wav finishes. clip.drain() says it's blocking but it's not. The clip isn't running RIGHT AFTER start(). The only working but UGLY way I found is:

// ...
clip.start();
while (!clip.isRunning())
    Thread.sleep(10);
while (clip.isRunning())
    Thread.sleep(10);
clip.close();

%x is a format specifier that format and output the hex value. If you are providing int or long value, it will convert it to hex value.

%02x means if your provided value is less than two digits then 0 will be prepended.

You provided value 16843009 and it has been converted to 1010101 which a hex value.

$data = file_get_contents('php://input');
echo $data;

This worked for me.

You can do something like this:

public class Example
{
    public String name;
    public String location;

    public String[] getExample()
    {
        String ar[] = new String[2];
        ar[0]= name;
        ar[1] =  location;
        return ar; //returning two values at once
    }
}

I was trying to install nginx from here - http://nginx.org/en/docs/windows.html

Going to http://localhost/ will show something, at least a proper "not found" message
This is because 80 is the default port, and it was taken by other processes.

Now run below command:

net stop http

    // Above command stopped below services  
    // - SSDP Discovery  
    // - Print Spooler  
    // - BranchCache  
    // - Function Discovery Resource Publication  
    // - Function Discovery Provider Host  

Now, going to http://localhost/ will fail with a broken link page message.

Main process was BranchCache
This process, after stopped, will restart in a few seconds.
So we need to run other commands we need soon, an example below:

// this will stop
net stop http

// immeidately run other command you want to
start nginx

Now, going to http://localhost/ gave me:

Welcome to nginx!

Hope that helps.

You can create a function like this:

CREATE FUNCTION [dbo].[f_convert_int_to_2_digits](@input int)
RETURNS varchar(10)
AS
BEGIN
    --return value
    DECLARE @return varchar(10)

    if @input < 10
    begin
    set @return = '0' + convert(varchar(1), @valor)
end
    else
    begin
        set @return = convert(varchar(10), @input)
    end

    -- return result
    RETURN @return

END

and then use it everywhere:
select [dbo].[f_convert_int_to_2_digits](<some int>)

The answers presented so far fail to check that the Base64 string has all pad bits set to 0, as required for it to be the canonical representation of Base64 (which is important in some environments, see https://tools.ietf.org/html/rfc4648#section-3.5) and therefore, they allow aliases that are different encodings for the same binary string. This could be a security problem in some applications.

Here is the regexp that verifies that the given string is not just valid base64, but also the canonical base64 string for the binary data:

^(?:[A-Za-z0-9+/]{4})*(?:[A-Za-z0-9+/][AQgw]==|[A-Za-z0-9+/]{2}[AEIMQUYcgkosw048]=)?$

The cited RFC considers the empty string as valid (see https://tools.ietf.org/html/rfc4648#section-10) therefore the above regex also does.

The equivalent regular expression for base64url (again, refer to the above RFC) is:

^(?:[A-Za-z0-9_-]{4})*(?:[A-Za-z0-9_-][AQgw]==|[A-Za-z0-9_-]{2}[AEIMQUYcgkosw048]=)?$

For completeness, I would add that, if you wanted to copy an entire directory full of controlled AND uncontrolled files, you could use the following:

git mv old new
git checkout HEAD old

The uncontrolled files will be copied over, so you should clean them up:

git clean -fdx new

As gratitude to the timely help I got from here - a minor update to above.

$query = "UPDATE `db`.`table` SET `fieldname`=  str_to_date(  fieldname, '%d/%m/%Y')";

If you cannot see the "Scripts" tab, make sure you are launching Chrome with the right arguments. I had this problem when I launched Chrome for debugging server-side JavaScript with the argument --remote-shell-port=9222. I have no problem if I launch Chrome with no argument.

You can use Simple JSON for PHP. It sends the headers help you to forge the JSON.

It looks like :

<?php
// Include the json class
include('includes/json.php');

// Then create the PHP-Json Object to suits your needs

// Set a variable ; var name = {}
$Json = new json('var', 'name'); 
// Fire a callback ; callback({});
$Json = new json('callback', 'name'); 
// Just send a raw JSON ; {}
$Json = new json();

// Build data
$object = new stdClass();
$object->test = 'OK';
$arraytest = array('1','2','3');
$jsonOnly = '{"Hello" : "darling"}';

// Add some content
$Json->add('width', '565px');
$Json->add('You are logged IN');
$Json->add('An_Object', $object);
$Json->add("An_Array",$arraytest);
$Json->add("A_Json",$jsonOnly);

// Finally, send the JSON.

$Json->send();
?>

I think I found the answer:

In the .service file, I needed to add /bin/bash before the path to the script.

For example, for backup.service:

ExecStart=/bin/bash /home/user/.scripts/backup.sh

As opposed to:

ExecStart=/home/user/.scripts/backup.sh

I'm not sure why. Perhaps fish. On the other hand, I have another script running for my email, and the service file seems to run fine without /bin/bash. It does use default.target instead multi-user.target, though.

Most of the tutorials I came across don't prepend /bin/bash, but I then saw this SO answer which had it, and figured it was worth a try.

The service file executes the script, and the timer is listed in systemctl --user list-timers, so hopefully this will work.

Update: I can confirm that everything is working now.

Use the array list which is actually implement array. It takes initially array of size 4 and when it gets full, a new array is created with its double size and the data of first array get copied into second array, now the new item is inserted into new array. Also the name of second array creates an alias of first so that it can be accessed by the same name as previous and the first array gets disposed

Are you using .NET 3.5? You could use the ZipPackage class and related classes. Its more than just zipping up a file list because it wants a MIME type for each file you add. It might do what you want.

I'm currently using these classes for a similar problem to archive several related files into a single file for download. We use a file extension to associate the download file with our desktop app. One small problem we ran into was that its not possible to just use a third-party tool like 7-zip to create the zip files because the client side code can't open it -- ZipPackage adds a hidden file describing the content type of each component file and cannot open a zip file if that content type file is missing.

Both answers are correct. If you user .TO -method then the semicolumn is OK - but not for the addrecipients-method. There you need to split, e.g. :

                Dim Splitter() As String
                Splitter = Split(AddrMail, ";")
                For Each Dest In Splitter
                    .Recipients.Add (Trim(Dest))
                Next

There is an ordered set (possible new link) recipe for this which is referred to from the Python 2 Documentation. This runs on Py2.6 or later and 3.0 or later without any modifications. The interface is almost exactly the same as a normal set, except that initialisation should be done with a list.

OrderedSet([1, 2, 3])

This is a MutableSet, so the signature for .union doesn't match that of set, but since it includes __or__ something similar can easily be added:

@staticmethod
def union(*sets):
    union = OrderedSet()
    union.union(*sets)
    return union

def union(self, *sets):
    for set in sets:
        self |= set

In the simplest form, I think a dimension table is something like a 'Master' table - that keeps a list of all 'items', so to say.

A fact table is a transaction table which describes all the transactions. In addition, aggregated (grouped) data like total sales by sales person, total sales by branch - such kinds of tables also might exist as independent fact tables.

I had the problem that the browser doesn't use ES6.

I have fix it with:

 <script type="module" src="index.js"></script>

The type module tells the browser to use ES6.

export const bla = [1,2,3];

import {bla} from './example.js';

Then it should work.

You probably shouldn't rely on textual output of a command to decide this, especially when the ping command gives you a perfectly good return value:

The ping utility returns an exit status of zero if at least one response was heard from the specified host; a status of two if the transmission was successful but no responses were received; or another value from <sysexits.h> if an error occurred.

In other words, use something like:

((count = 100))                            # Maximum number to try.
while [[ $count -ne 0 ]] ; do
    ping -c 1 8.8.8.8                      # Try once.
    rc=$?
    if [[ $rc -eq 0 ]] ; then
        ((count = 1))                      # If okay, flag to exit loop.
    fi
    ((count = count - 1))                  # So we don't go forever.
done

if [[ $rc -eq 0 ]] ; then                  # Make final determination.
    echo `say The internet is back up.`
else
    echo `say Timeout.`
fi

Just use the entity code 
 for a linebreak in a title attribute.

<a title="First Line &#xA;Second Line">Hover Me </a>

Here is a TypeScript version of @meseern's answer that avoids unnecessary assignments on re-render:

import React, { useState, useEffect } from 'react';

export function useContainerDimensions(myRef: React.RefObject<any>) {
  const [dimensions, setDimensions] = useState({ width: 0, height: 0 });

  useEffect(() => {
    const getDimensions = () => ({
      width: (myRef && myRef.current.offsetWidth) || 0,
      height: (myRef && myRef.current.offsetHeight) || 0,
    });

    const handleResize = () => {
      setDimensions(getDimensions());
    };

    if (myRef.current) {
      setDimensions(getDimensions());
    }

    window.addEventListener('resize', handleResize);

    return () => {
      window.removeEventListener('resize', handleResize);
    };
  }, [myRef]);

  return dimensions;
}

I saw another question on just this topic recently (streaming pdf into iframe using dataurl only works in chrome).

I've constructed pdfs in the ast and streamed them to the browser. I was creating them first with fdf, then with a pdf class I wrote myself - in each case the pdf was created from data retrieved from a COM object based on a couple of of GET params passed in via the url.

From looking at your data sent recieved in the ajax call, it looks like you're nearly there. I haven't played with the code for a couple of years now and didn't document it as well as I'd have cared to, but - I think all you need to do is set the target of an iframe to be the url you get the pdf from. Though this may not work - the file that oututs the pdf may also have to outut a html response header first.

In a nutshell, this is the output code I used:

//We send to a browser
header('Content-Type: application/pdf');
if(headers_sent())
    $this->Error('Some data has already been output, can\'t send PDF file');
header('Content-Length: '.strlen($this->buffer));
header('Content-Disposition: inline; filename="'.$name.'"');
header('Cache-Control: private, max-age=0, must-revalidate');
header('Pragma: public');
ini_set('zlib.output_compression','0');
echo $this->buffer;

So, without seeing the full response text fro the ajax call I can't really be certain what it is, though I'm inclined to think that the code that outputs the pdf you're requesting may only be doig the equivalent of the last line in the above code. If it's code you have control over, I'd try setting the headers - then this way the browser can just deal with the response text - you don't have to bother doing a thing to it.

I simply constructed a url for the pdf I wanted (a timetable) then created a string that represented the html for an iframe of the desired sie, id etc that used the constructed url as it's src. As soon as I set the inner html of a div to the constructed html string, the browser asked for the pdf and then displayed it when it was received.

function  showPdfTt(studentId)
{
    var url, tgt;
    title = byId("popupTitle");
    title.innerHTML = "Timetable for " + studentId;
    tgt = byId("popupContent");
    url = "pdftimetable.php?";
    url += "id="+studentId;
    url += "&type=Student";
    tgt.innerHTML = "<iframe onload=\"centerElem(byId('box'))\" src='"+url+"' width=\"700px\" height=\"500px\"></iframe>";
}

EDIT: forgot to mention - you can send binary pdf's in this manner. The streams they contain don't need to be ascii85 or hex encoded. I used flate on all the streams in the pdf and it worked fine.

Problem: root@localhost is unable to connect to a fresh installation of mysql-community-server on openSUSE 42.2-1.150.x86_64. Mysql refuses connections - period.

Solution:

$ ls -l /var/lib/mysql/mysql/user.*
-rw-rw---- 1 mysql mysql     0 Apr 29 19:44 /var/lib/mysql/mysql/user.MYD
-rw-rw---- 1 mysql mysql  1024 Apr 29 19:44 /var/lib/mysql/mysql/user.MYI
-rw-rw---- 1 mysql mysql 10684 Apr 29 19:44 /var/lib/mysql/mysql/user.frm

File user.MYD has 0 size (really ?!). I copied all 3 files from another working system.

$ /usr/sbin/rcmysql stop
$ cd /var/lib/mysql/mysql/
$ scp root@othersytem:/var/lib/mysql/mysql/user.* ./
$ /usr/sbin/rcmysql start
$ cd -
$ mysql -u root -p

I was able to log in. Then, it was just a matter of re-applying all schema privileges. Also, if you disabled IPv6, re-enable it temporary so that root@::1 account can also work.

Had the same problem and the solution was to reauthorize the user. Check it here:

<?php

 require_once("src/facebook.php");

  $config = array(
      'appId' => '1424980371051918',
      'secret' => '2ed5c1260daa4c44673ba6fbc348c67d',
      'fileUpload' => false // optional
  );

  $facebook = new Facebook($config);

//Authorizing app:

?>
<a href="<?php echo $facebook->getLoginUrl(); ?>">Login con fb</a>

Saved project and opened on my test enviroment and it worked again. As I did, you can comment your previous code and try.

https://anzeljg.github.io/rin2/book2/2405/docs/tkinter/universal.html

w.winfo_children()
Returns a list of all w's children, in their stacking order from lowest (bottom) to highest (top).

for widget in frame.winfo_children():
    widget.destroy()

Will destroy all the widget in your frame. No need for a second frame.

First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.

If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
  If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
    'do something
  End If
End If

You can do like this:

SELECT convert(datetime, convert(date, '27-09-2013', 103), 103) 

You were close with

Contact.update({phone:request.phone}, contact, {upsert: true}, function(err){...})

but your second parameter should be an object with a modification operator for example

Contact.update({phone:request.phone}, {$set: { phone: request.phone }}, {upsert: true}, function(err){...})

You've already got it: A if test else B is a valid Python expression. The only problem with your dict comprehension as shown is that the place for an expression in a dict comprehension must have two expressions, separated by a colon:

{ (some_key if condition else default_key):(something_if_true if condition
          else something_if_false) for key, value in dict_.items() }

The final if clause acts as a filter, which is different from having the conditional expression.

It's simple-

SELECT empname,
       empid,
       (SELECT COUNT (profileid)
          FROM profile
         WHERE profile.empid = employee.empid)
           AS number_of_profiles
  FROM employee;

It is even simpler when you use a table join like this:

  SELECT e.empname, e.empid, COUNT (p.profileid) AS number_of_profiles
    FROM employee e LEFT JOIN profile p ON e.empid = p.empid
GROUP BY e.empname, e.empid;

Explanation for the subquery:

Essentially, a subquery in a select gets a scalar value and passes it to the main query. A subquery in select is not allowed to pass more than one row and more than one column, which is a restriction. Here, we are passing a count to the main query, which, as we know, would always be only a number- a scalar value. If a value is not found, the subquery returns null to the main query. Moreover, a subquery can access columns from the from clause of the main query, as shown in my query where employee.empid is passed from the outer query to the inner query.

Edit:

When you use a subquery in a select clause, Oracle essentially treats it as a left join (you can see this in the explain plan for your query), with the cardinality of the rows being just one on the right for every row in the left.

Explanation for the left join

A left join is very handy, especially when you want to replace the select subquery due to its restrictions. There are no restrictions here on the number of rows of the tables in either side of the LEFT JOIN keyword.

For more information read Oracle Docs on subqueries and left join or left outer join.

You can't do window.history.back(); and location.reload(); in the same function.

window.history.back() breaks the javascript flow and redirects to previous page, location.reload() is never processed.

location.reload() has to be called on the page you redirect to when using window.history.back().

I would used an url to redirect instead of history.back, that gives you both a redirect and refresh.

Omkar's answer is quite comprehensive.

But some part of the Global config part has changed.

According to the spring boot 2.0.2.RELEASE reference

As of version 4.2, Spring MVC supports CORS. Using controller method CORS configuration with @CrossOrigin annotations in your Spring Boot application does not require any specific configuration. Global CORS configuration can be defined by registering a WebMvcConfigurer bean with a customized addCorsMappings(CorsRegistry) method, as shown in the following example:

@Configuration
public class MyConfiguration {

    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/api/**");
            }
        };
    }
}

Most answer in this post using WebMvcConfigurerAdapter, however

The type WebMvcConfigurerAdapter is deprecated

Since Spring 5 you just need to implement the interface WebMvcConfigurer:

public class MvcConfig implements WebMvcConfigurer {

This is because Java 8 introduced default methods on interfaces which cover the functionality of the WebMvcConfigurerAdapter class

Hi I've blogged about writing a sudoku solver from scratch in Python and currently writing a whole series about writing a constraint programming solver in Julia (another high level but faster language) You can read the sudoku problem from a file which seems to be easier more handy than a gui or cli way. The general idea it uses is constraint programming. I use the all different / unique constraint but I coded it myself instead of using a constraint programming solver.

If someone is interested:

• The old Python version: https://opensourc.es/blog/sudoku
• The new Julia series: https://opensourc.es/blog/constraint-solver-1

It wants the full time in DD-MM-YYYY_HH-MM-SS.TT where TT is the ticks. The exception says it all.

First off, Daniel's answer is the correct, safe option.

For the specific case of changing from SQL_ASCII to something else, you can cheat and simply poke the pg_database catalogue to reassign the database encoding. This assumes you've already stored any non-ASCII characters in the expected encoding (or that you simply haven't used any non-ASCII characters).

Then you can do:

update pg_database set encoding = pg_char_to_encoding('UTF8') where datname = 'thedb'

This will not change the collation of the database, just how the encoded bytes are converted into characters (so now length('£123') will return 4 instead of 5). If the database uses 'C' collation, there should be no change to ordering for ASCII strings. You'll likely need to rebuild any indices containing non-ASCII characters though.

Caveat emptor. Dumping and reloading provides a way to check your database content is actually in the encoding you expect, and this doesn't. And if it turns out you did have some wrongly-encoded data in the database, rescuing is going to be difficult. So if you possibly can, dump and reinitialise.

The C# struct is a lightweight alternative to a class. It can do almost the same as a class, but it's less "expensive" to use a struct rather than a class. The reason for this is a bit technical, but to sum up, new instances of a class is placed on the heap, where newly instantiated structs are placed on the stack. Furthermore, you are not dealing with references to structs, like with classes, but instead you are working directly with the struct instance. This also means that when you pass a struct to a function, it is by value, instead of as a reference. There is more about this in the chapter about function parameters.

So, you should use structs when you wish to represent more simple data structures, and especially if you know that you will be instantiating lots of them. There are lots of examples in the .NET framework, where Microsoft has used structs instead of classes, for instance the Point, Rectangle and Color struct.

Here is the complete code

#include <bits/stdc++.h>

using namespace std;

typedef unsigned char BYTE;

int main() {
  //method 1;
  std::vector<BYTE> data = {'H','E','L','L','O','1','2','3'};
  //string constructor accepts only const char
  std::string s((const char*)&(data[0]), data.size());
  std::cout << s << std::endl;

  //method 2
  std::string s2(data.begin(),data.end());
  std::cout << s2 << std::endl;

  //method 3
  std::string s3(reinterpret_cast<char const*>(&data[0]), data.size()) ;
  std::cout << s3 << std::endl;
 
  return 0;
}

Use toString when you need to display the name to the user.

Use name when you need the name for your program itself, e.g. to identify and differentiate between different enum values.

avoid the memcpy, I say. No reason to mess with pointer operations unless you really have to. Also, it will only work for POD types (like int) but would fail if you're dealing with types that require construction.

My solution on Ubuntu 10.04 using java-sun 1.6.0_24 having all jars in "lib" directory:

java -cp .:lib/* my.main.Class

If this fails, the following command should work (prints out all *.jars in lib directory to the classpath param)

java -cp $(for i in lib/*.jar ; do echo -n $i: ; done). my.main.Class

I don't know if this is Ruby intention or if this is a bug but try this code below. This code was run on Ruby version 2.5.1 and was on a Linux system.

puts 1 > -1 and 257 < 256
# => false

puts 1 > -1 && 257 < 256
# => true

You can use Cell.Interior.Color, I've used it to count the number of cells in a range that have a given background color (ie. matching my legend).

If You have jar file then create bat file with:

java -jar NameOfJar.jar

add this before exporting class

@Injectable({
  providedIn: 'root'
})  

Return as a tuple, e.g.

def foo (a):
    x=a
    y=a*2
    return (x,y)

If you deal with dates it is a good idea to look at the joda time library for a more sane Date manipulation model.

http://joda-time.sourceforge.net/

For those who like me could not solve this problem with the solutions above, I sugest verifying if you initialize the $(element).datetimepicker(...) in different locations at the same time.

In my case, after a long time, I found a global.js interfering with another datetimepicker initialization.

If you need for some reason maintain work with different initializations, in different files, remember to remove the datetimepicker before each one with:

$(element).datetimepicker('remove')

Reference: https://www.malot.fr/bootstrap-datetimepicker/index.php#methods

Edit: This solution still needs to import the language files correctly, right after the bootstrap-datetimepicker.js.

I hope this helps!

Well, Bootstrap Carousel has various parameters to control.

i.e.

Interval: Specifies the delay (in milliseconds) between each slide.

pause: Pauses the carousel from going through the next slide when the mouse pointer enters the carousel, and resumes the sliding when the mouse pointer leaves the carousel.

wrap: Specifies whether the carousel should go through all slides continuously, or stop at the last slide

Note: This is for the further help.. I mean how can you customise or change default behaviour once carousel is loaded.

int is a primitive type and not an object. That means that there are no methods associated with it. Integer is an object with methods (such as parseInt).

With newer java there is functionality for auto boxing (and unboxing). That means that the compiler will insert Integer.valueOf(int) or integer.intValue() where needed. That means that it is actually possible to write

Integer n = 9;

which is interpreted as

Integer n = Integer.valueOf(9);

For anyone checking this question recently, Rails 5.2+ now has ActiveStorage by default & I highly recommend checking it out.

Since it is part of the core Rails 5.2+ now, it is very well integrated & has excellent capabilities out of the box (still all other well-known gems like Carrierwave, Shrine, paperclip,... are great but this one offers very good features that we can consider for any new Rails project)

Paperclip team deprecated the gem in favor of the Rails ActiveStorage.

Here is the github page for the ActiveStorage & plenty of resources are available everywhere

Also I found this video to be very helpful to understand the features of Activestorage

Starting Xcode 9, in Objective-C:

if (@available(iOS 11, *)) {
    // iOS 11 (or newer) ObjC code
} else {
    // iOS 10 or older code
}

Starting Xcode 7, in Swift:

if #available(iOS 11, *) {
    // iOS 11 (or newer) Swift code
} else {
    // iOS 10 or older code
}

For the version, you can specify the MAJOR, the MINOR or the PATCH (see http://semver.org/ for definitions). Examples:

• iOS 11 and iOS 11.0 are the same minimal version
• iOS 10, iOS 10.3, iOS 10.3.1 are different minimal versions

You can input values for any of those systems:

• iOS, macOS, watchOS, tvOS

Real case example taken from one of my pods:

if #available(iOS 10.0, tvOS 10.0, *) {
    // iOS 10+ and tvOS 10+ Swift code
} else {
    // iOS 9 and tvOS 9 older code

I didn't manage to understand what np.reshape() does until I read this article.

Mechanically it is clear what reshape() does. But how do we interpret the data before and after reshape?

The missing piece for me was:

When we train a machine learning model, the nesting levels of arrays have precisely defined meaning.

This means that the reshape operation has to be keenly aware both points below before the operation has any meaning:

• the data it operates on (how the reshape intput looks like)
• how the algorithm/model expects the reshaped data to be (how the reshape output looks like)

For example:

The external array contains observations/rows. The inner array contains columns/features. This causes two special cases when we have either an array of multiple observations of only one feature or a single observation of multiple features.

For more advanced example: See this stackoverflow question

If you need to see the output of the execute, use CALL together with or instead of START.

Example:

CALL "C:\Program Files\Certain Directory\file.exe" -param PAUSE

This will run the file.exe and print back whatever it outputs, in the same command window. Remember the PAUSE after the call or else the window may close instantly.

You can use java System.properties, for using them from eclipse you could:

1. Add -Dlabel="label_value" in the VM arguments of the test Run Configuration like this:

2. Then run the test:

   import org.junit.Test;
   import static org.junit.Assert.assertEquals;
   
   public class Main {
       @Test
       public void test(){
           System.out.println(System.getProperty("label"));
           assertEquals("label_value", System.getProperty("label"));
       }
   }
   

3. Finally it should pass the test and output this in the console:

   label_value

    }

    var i = document.styleSheets.length-1;
    var ss = document.styleSheets[i];

    var l=0;

      l = ss.cssRules.length;
    } else if (ss.rules) {

It looks like you want to define Truck as a Class with properties NumberOfAxles, AxleWeights & AxleSpacings.

This can be defined in a CLASS MODULE (here named clsTrucks)

Option Explicit

Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double


Public Property Get truckID() As String
    truckID = tID
End Property

Public Property Let truckID(value As String)
    tID = value
End Property

Public Property Get truckNumberOfAxles() As Double
    truckNumberOfAxles = tNumberOfAxles
End Property

Public Property Let truckNumberOfAxles(value As Double)
    tNumberOfAxles = value
End Property

Public Property Get truckAxleSpacings() As Double
    truckAxleSpacings = tAxleSpacings
End Property

Public Property Let truckAxleSpacings(value As Double)
    tAxleSpacings = value
End Property

then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.

Option Explicit

Public TruckCollection As New Collection

Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long

    'Add 5 trucks
    For i = 1 To 5
        Set tempTruck = New clsTrucks
        'Random data
        tempTruck.truckID = "Truck" & i
        tempTruck.truckAxleSpacings = 13.5 + i
        tempTruck.truckNumberOfAxles = 20.5 + i

        'tempTruck.truckID is the collection key
        TruckCollection.Add tempTruck, tempTruck.truckID
    Next i

    'retrieve 5 trucks
    For i = 1 To 5
        'retrieve by collection index
        Debug.Print TruckCollection(i).truckAxleSpacings
        'retrieve by key
        Debug.Print TruckCollection("Truck" & i).truckAxleSpacings

    Next i

End Sub

There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.

EDIT:

If you don't need to support IE10, you can simply use: document.location.origin

Original answer, if you need legacy support

You can get all this and more by inspecting the location object:

location = {
  host: "stackoverflow.com",
  hostname: "stackoverflow.com",
  href: "http://stackoverflow.com/questions/2300771/jquery-domain-get-url",
  pathname: "/questions/2300771/jquery-domain-get-url",
  port: "",
  protocol: "http:"
}

so:

location.host 

would be the domain, in this case stackoverflow.com. For the complete first part of the url, you can use:

location.protocol + "//" + location.host

which in this case would be http://stackoverflow.com

No jQuery required.

You can try the following:

theAnchorText = "I'm home";

OR

theAnchorText = 'I\'m home';

IO manipulators are what you need. setw, in particular. Here's an example from the reference page:

// setw example
#include <iostream>
#include <iomanip>
using namespace std;

int main () {
  cout << setw (10);
  cout << 77 << endl;
  return 0;
}

Justifying the field to the left and right is done with the left and right manipulators.

Also take a look at setfill. Here's a more complete tutorial on formatting C++ output with io manipulators.

What about having a live validation on the textbox, and once it goes over 2000 (or whatever the maximum threshold is) then display 'This email is too long to be completed in the browser, please <span class="launchEmailClientLink">launch what you have in your email client</span>'

To which I'd have

.launchEmailClientLink {
cursor: pointer;
color: #00F;
}

and jQuery this into your onDomReady

$('.launchEmailClientLink').bind('click',sendMail);

For use in a /etc/hosts file as a simple ad blocking technique to cause a domain to fail to resolve, the 0.0.0.0 address has been widely used because it causes the request to immediately fail without even trying, because it's not a valid or routable address. This is in comparison to using 127.0.0.1 in that place, where it will at least check to see if your own computer is listening on the requested port 80 before failing with 'connection refused.' Either of those addresses being used in the hosts file for the domain will stop any requests from being attempted over the actual network, but 0.0.0.0 has gained favor because it's more 'optimal' for the above reason. "127" IPs will attempt to hit your own computer, and any other IP will cause a request to be sent to the router to try to route it, but for 0.0.0.0 there's nowhere to even send a request to.

All that being said, having any IP listed in your hosts file for the domain to be blocked is sufficient, and you wouldn't need or want to also put an ipv6 address in your hosts file unless -- possibly -- you don't have ipv4 enabled at all. I'd be really surprised if that was the case, though. And still though, I think having the host appear in /etc/hosts with a bad ipv4 address when you don't have ipv4 enabled would still give you the result you are looking for which is for it to fail, instead of looking up the real DNS of say, adserver-example.com and getting back either a v4 or v6 IP.

For page object model -

 @FindBy(xpath="//foo")
   public WebElement textBox;

now in your function

 public void clearExistingText(String newText){
    textBox.clear();
    textBox.sendKeys(newText);
  }

for general selenium architecture -

driver.findElement(By.xpath("//yourxpath")).clear();
driver.findElement(By.xpath("//yourxpath")).sendKeys("newText");

well here is common usage of getter setter in actual use case,

public class OrderItem 
{
public int Id {get;set;}
public int quantity {get;set;}
public int Price {get;set;}
public int TotalAmount {get {return this.quantity *this.Price;}set;}
}

UIAlertView is deprecated on iOS 8. Therefore, to create an alert on iOS 8 and above, it is recommended to use UIAlertController:

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Title" message:@"Alert Message" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *defaultAction = [UIAlertAction actionWithTitle:@"Ok" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

    // Enter code here
}];
[alert addAction:defaultAction];

// Present action where needed
[self presentViewController:alert animated:YES completion:nil];

This is how I have implemented it.

Instead of using np.hist2d, which in general produces quite ugly histograms, I would like to recycle py-sphviewer, a python package for rendering particle simulations using an adaptive smoothing kernel and that can be easily installed from pip (see webpage documentation). Consider the following code, which is based on the example:

import numpy as np
import numpy.random
import matplotlib.pyplot as plt
import sphviewer as sph

def myplot(x, y, nb=32, xsize=500, ysize=500):   
    xmin = np.min(x)
    xmax = np.max(x)
    ymin = np.min(y)
    ymax = np.max(y)

    x0 = (xmin+xmax)/2.
    y0 = (ymin+ymax)/2.

    pos = np.zeros([len(x),3])
    pos[:,0] = x
    pos[:,1] = y
    w = np.ones(len(x))

    P = sph.Particles(pos, w, nb=nb)
    S = sph.Scene(P)
    S.update_camera(r='infinity', x=x0, y=y0, z=0, 
                    xsize=xsize, ysize=ysize)
    R = sph.Render(S)
    R.set_logscale()
    img = R.get_image()
    extent = R.get_extent()
    for i, j in zip(xrange(4), [x0,x0,y0,y0]):
        extent[i] += j
    print extent
    return img, extent
    
fig = plt.figure(1, figsize=(10,10))
ax1 = fig.add_subplot(221)
ax2 = fig.add_subplot(222)
ax3 = fig.add_subplot(223)
ax4 = fig.add_subplot(224)


# Generate some test data
x = np.random.randn(1000)
y = np.random.randn(1000)

#Plotting a regular scatter plot
ax1.plot(x,y,'k.', markersize=5)
ax1.set_xlim(-3,3)
ax1.set_ylim(-3,3)

heatmap_16, extent_16 = myplot(x,y, nb=16)
heatmap_32, extent_32 = myplot(x,y, nb=32)
heatmap_64, extent_64 = myplot(x,y, nb=64)

ax2.imshow(heatmap_16, extent=extent_16, origin='lower', aspect='auto')
ax2.set_title("Smoothing over 16 neighbors")

ax3.imshow(heatmap_32, extent=extent_32, origin='lower', aspect='auto')
ax3.set_title("Smoothing over 32 neighbors")

#Make the heatmap using a smoothing over 64 neighbors
ax4.imshow(heatmap_64, extent=extent_64, origin='lower', aspect='auto')
ax4.set_title("Smoothing over 64 neighbors")

plt.show()

which produces the following image:

As you see, the images look pretty nice, and we are able to identify different substructures on it. These images are constructed spreading a given weight for every point within a certain domain, defined by the smoothing length, which in turns is given by the distance to the closer nb neighbor (I've chosen 16, 32 and 64 for the examples). So, higher density regions typically are spread over smaller regions compared to lower density regions.

The function myplot is just a very simple function that I've written in order to give the x,y data to py-sphviewer to do the magic.

I made a script to solve this which is here. You don't need any extra software for this. Installation:
brew install akashaggarwal7/tools/tsay
Usage:
sleep 5; tsay

Using Acrobat reader is not a good solution, especially command line attributes are not documented. Additionally Acrobat reader's window stays open after printing process. PDF files are well known by printer drivers, so you may find better tools, like 2Printer.exe or RawFilePrinter.exe. In my opinion RawFilePrinter has better support and clear licencing process (you pay donation once and you can redistribute RawFilePrinter in many project you like - even new versions work with previously purchased license)

RawFilePrinter.exe -p "c:\Users\Me\Desktop\mypdffile.pdf" "Canon Printer" 
IF %ERRORLEVEL% 1(
    echo "Error!"
)

just to extend Shankars and amals answers with simple unit testing:

/**
 *
 * workaround HTTPS problems with file_get_contents
 *
 * @param $url
 * @return boolean|string
 */
function curl_get_contents($url)
{
    $data = FALSE;
    if (filter_var($url, FILTER_VALIDATE_URL))
    {
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        $data = curl_exec($ch);
        curl_close($ch);
    }
    return $data;
}
// then in the unit tests:
public function test_curl_get_contents()
{
    $this->assertFalse(curl_get_contents(NULL));
    $this->assertFalse(curl_get_contents('foo'));
    $this->assertTrue(strlen(curl_get_contents('https://www.google.com')) > 0);
}

Log in the Keycloak admin console website, select the realm and its client, then make sure all URIs of the client are prefixed with the protocol, that is, with http:// for example. An example would be http://localhost:8082/*

Another way to solve the issue, is to view the Keycloak server console output, locate the line stating the request was refused, copy from it the redirect_uri displayed value and paste it in the * Valid Redirect URIs field of the client in the Keycloak admin console website. The requested URI is then one of the acceptables.

This should work. You may save the following in a batch file:

TASKKILL /F /IM chrome.exe
start chrome.exe --args --disable-web-security
pause

What about just using a global variable within your library, like so?

single.dart:

library singleton;

var Singleton = new Impl();

class Impl {
  int i;
}

main.dart:

import 'single.dart';

void main() {
  var a = Singleton;
  var b = Singleton;
  a.i = 2;
  print(b.i);
}

Or is this frowned upon?

The singleton pattern is necessary in Java where the concept of globals doesn't exist, but it seems like you shouldn't need to go the long way around in Dart.
