You can use

TF_FORCE_GPU_ALLOW_GROWTH=true

in your environment variables.

In tensorflow code:

bool GPUBFCAllocator::GetAllowGrowthValue(const GPUOptions& gpu_options) {
  const char* force_allow_growth_string =
      std::getenv("TF_FORCE_GPU_ALLOW_GROWTH");
  if (force_allow_growth_string == nullptr) {
    return gpu_options.allow_growth();
}

simple:

var promiseResolve, promiseReject;

var promise = new Promise(function(resolve, reject){
  promiseResolve = resolve;
  promiseReject = reject;
});

promiseResolve();

With the recent release of bootstrap 3, and the glyphicons being merged back to the main Bootstrap repo, Bootstrap CDN is now serving the complete Bootstrap 3.0 css including Glyphicons. The Bootstrap css reference is all you need to include: Glyphicons and its dependencies are on relative paths on the CDN site and are referenced in bootstrap.min.css.

In html:

<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet">

In css:

 @import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css");

Here is a working demo.

Note that you have to use .glyphicon classes instead of .icon:

Example:

<span class="glyphicon glyphicon-heart"></span>

Also note that you would still need to include bootstrap.min.js for usage of Bootstrap JavaScript components, see Bootstrap CDN for url.

If you want to use the Glyphicons separately, you can do that by directly referencing the Glyphicons css on Bootstrap CDN.

In html:

<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css" rel="stylesheet">

In css:

@import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css");

Since the css file already includes all the needed Glyphicons dependencies (which are in a relative path on the Bootstrap CDN site), adding the css file is all there is to do to start using Glyphicons.

Here is a working demo of the Glyphicons without Bootstrap.

You could also create an ssh tunnel.

docker-compose.yml:

---

version: '2'

services:
  kibana:
    image: "kibana:4.5.1"
    links:
      - elasticsearch
    volumes:
      - ./config/kibana:/opt/kibana/config:ro

  elasticsearch:
    build:
      context: .
      dockerfile: ./docker/Dockerfile.tunnel
    entrypoint: ssh
    command: "-N elasticsearch -L 0.0.0.0:9200:localhost:9200"

docker/Dockerfile.tunnel:

FROM buildpack-deps:jessie

RUN apt-get update && \
    DEBIAN_FRONTEND=noninteractive \
    apt-get -y install ssh && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/*

COPY ./config/ssh/id_rsa /root/.ssh/id_rsa
COPY ./config/ssh/config /root/.ssh/config
COPY ./config/ssh/known_hosts /root/.ssh/known_hosts
RUN chmod 600 /root/.ssh/id_rsa && \
    chmod 600 /root/.ssh/config && \
    chown $USER:$USER -R /root/.ssh

config/ssh/config:

# Elasticsearch Server
Host elasticsearch
    HostName jump.host.czerasz.com
    User czerasz
    ForwardAgent yes
    IdentityFile ~/.ssh/id_rsa

This way the elasticsearch has a tunnel to the server with the running service (Elasticsearch, MongoDB, PostgreSQL) and exposes port 9200 with that service.

Here's the fiddle.

Put this at the top of your .py file (for python 2.x)

#!/usr/bin/env python 

or for python 3.x

#!/usr/bin/env python3

This should look up the python environment, without it, it will execute the code as if it were not python code, but straight to the CLI. If you need to specify a manual location of python environment put

#!/#path/#to/#python

Thought I would chip in here with when I have found ON to be more useful than USING. It is when OUTER joins are introduced into queries.

ON benefits from allowing the results set of the table that a query is OUTER joining onto to be restricted while maintaining the OUTER join. Attempting to restrict the results set through specifying a WHERE clause will, effectively, change the OUTER join into an INNER join.

Granted this may be a relative corner case. Worth putting out there though.....

For example:

CREATE TABLE country (
   countryId int(10) unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT,
   country varchar(50) not null,
  UNIQUE KEY countryUIdx1 (country)
) ENGINE=InnoDB;

insert into country(country) values ("France");
insert into country(country) values ("China");
insert into country(country) values ("USA");
insert into country(country) values ("Italy");
insert into country(country) values ("UK");
insert into country(country) values ("Monaco");


CREATE TABLE city (
  cityId int(10) unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT,
  countryId int(10) unsigned not null,
  city varchar(50) not null,
  hasAirport boolean not null default true,
  UNIQUE KEY cityUIdx1 (countryId,city),
  CONSTRAINT city_country_fk1 FOREIGN KEY (countryId) REFERENCES country (countryId)
) ENGINE=InnoDB;


insert into city (countryId,city,hasAirport) values (1,"Paris",true);
insert into city (countryId,city,hasAirport) values (2,"Bejing",true);
insert into city (countryId,city,hasAirport) values (3,"New York",true);
insert into city (countryId,city,hasAirport) values (4,"Napoli",true);
insert into city (countryId,city,hasAirport) values (5,"Manchester",true);
insert into city (countryId,city,hasAirport) values (5,"Birmingham",false);
insert into city (countryId,city,hasAirport) values (3,"Cincinatti",false);
insert into city (countryId,city,hasAirport) values (6,"Monaco",false);

-- Gah. Left outer join is now effectively an inner join 
-- because of the where predicate
select *
from country left join city using (countryId)
where hasAirport
; 

-- Hooray! I can see Monaco again thanks to 
-- moving my predicate into the ON
select *
from country co left join city ci on (co.countryId=ci.countryId and ci.hasAirport)
; 

-split outputs an array, and you can save it to a variable like this:

$a = -split 'Once  upon    a     time'
$a[0]

Once

Another cute thing, you can have arrays on both sides of an assignment statement:

$a,$b,$c = -split 'Once  upon    a'
$c

a

In your own answer, you effectively do this:

Dim SrcRange As Range ' you should always declare things explicitly
Set SrcRange = Sheets("Src").Range("A2:A9")
SrcRange.Copy Destination:=Sheets("Dest").Range("A2")

You're not really "extracting" the range to a variable, you're setting a reference to the range.

In many situations, this can be more efficient as well as more flexible:

Dim Src As Variant
Src= Sheets("Src").Range("A2:A9").Value 'Read range to array
'Here you can add code to manipulate your Src array
'...
Sheets("Dest").Range("A2:A9").Value = Src 'Write array back to another range

There is also another way:

Fragment.instantiate(context, MyFragment.class.getName(), myBundle)

For Visual Studio 2015 the steps in the above answers apply but the applicationhost.config file is in a new location. In your "solution" folder follow the path, this is confusing if you upgraded and would have TWO versions of applicationhost.config on your machine.

\.vs\config

Within that folder you will see your applicationhost.config file

Alternatively you could just search your solution folder for the .config file and find it that way.

I personally used the following configuration:

With the following in my hosts file:

127.0.0.1       jam.net
127.0.0.1       www.jam.net

And the following in my applicationhost.config file:

<site name="JBN.Site" id="2">
    <application path="/" applicationPool="Clr4IntegratedAppPool">
        <virtualDirectory path="/" physicalPath="C:\Dev\Jam\shoppingcart\src\Web\JBN.Site" />
    </application>
    <bindings>
        <binding protocol="http" bindingInformation="*:49707:" />
            <binding protocol="http" bindingInformation="*:49707:localhost" /> 
    </bindings>
</site>

Remember to run your instance of visual studio 2015 as an administrator! If you don't want to do this every time I recomend this:

I hope this helps somebody, I had issues when trying to upgrade to visual studio 2015 and realized that none of my configurations were being carried over.

You can do this pretty easily with tagalog (https://github.com/dorkitude/tagalog)

For instance, while the standard python module writes to a file object opened in append mode, the App Engine module (https://github.com/dorkitude/tagalog/blob/master/tagalog_appengine.py) overrides this behavior and instead uses logging.INFO.

To get this behavior in an App Engine project, one could simply do:

import tagalog.tagalog_appengine as tagalog
tagalog.log('whatever message', ['whatever','tags'])

You could extend the module yourself and overwrite the log function without much difficulty.

In Oracle RBDMS you can achieve this behavior using REGEXP_LIKE function.

The following code will test if the string three is present in the list expression one|two|three|four|five (in which the pipe "|" symbol means OR logic operation).

SELECT 'Success !!!' result
FROM dual
WHERE REGEXP_LIKE('three', 'one|two|three|four|five');

RESULT
---------------------------------
Success !!!

1 row selected.

Preceding expression is equivalent to:

three=one OR three=two OR three=three OR three=four OR three=five

So it will succeed.

On the other hand, the following test will fail.

SELECT 'Success !!!' result
FROM dual
WHERE REGEXP_LIKE('ten', 'one|two|three|four|five');

no rows selected

There are several functions related to regular expressions (REGEXP_*) available in Oracle since 10g version. If you are an Oracle developer and interested this topic this should be a good beginning Using Regular Expressions with Oracle Database.

LINQ-to-SQL is a remarkable piece of technology that is very simple to use, and by and large generates very good queries to the back end. LINQ-to-EF was slated to supplant it, but historically has been extremely clunky to use and generated far inferior SQL. I don't know the current state of affairs, but Microsoft promised to migrate all the goodness of L2S into L2EF, so maybe it's all better now.

Personally, I have a passionate dislike of ORM tools (see my diatribe here for the details), and so I see no reason to favour L2EF, since L2S gives me all I ever expect to need from a data access layer. In fact, I even think that L2S features such as hand-crafted mappings and inheritance modeling add completely unnecessary complexity. But that's just me. ;-)

I will side with nategood's answer as it is complete and it seemed to have please your needs. Though, I would like to add a comment on identifying multiple (1 or more) resource that way:

http://our.api.com/Product/101404,7267261

In doing so, you:

Complexify the clients by forcing them to interpret your response as an array, which to me is counter intuitive if I make the following request: http://our.api.com/Product/101404

Create redundant APIs with one API for getting all products and the one above for getting 1 or many. Since you shouldn't show more than 1 page of details to a user for the sake of UX, I believe having more than 1 ID would be useless and purely used for filtering the products.

It might not be that problematic, but you will either have to handle this yourself server side by returning a single entity (by verifying if your response contains one or more) or let clients manage it.

Example

I want to order a book from Amazing. I know exactly which book it is and I see it in the listing when navigating for Horror books:

1. 10 000 amazing lines, 0 amazing test
2. The return of the amazing monster
3. Let's duplicate amazing code
4. The amazing beginning of the end

After selecting the second book, I am redirected to a page detailing the book part of a list:

--------------------------------------------
Book #1
--------------------------------------------
    Title: The return of the amazing monster
    Summary:
    Pages:
    Publisher:
--------------------------------------------

Or in a page giving me the full details of that book only?

---------------------------------
The return of the amazing monster
---------------------------------
Summary:
Pages:
Publisher:
---------------------------------

My Opinion

I would suggest using the ID in the path variable when unicity is guarantied when getting this resource's details. For example, the APIs below suggest multiple ways to get the details for a specific resource (assuming a product has a unique ID and a spec for that product has a unique name and you can navigate top down):

/products/{id}
/products/{id}/specs/{name}

The moment you need more than 1 resource, I would suggest filtering from a larger collection. For the same example:

/products?ids=

Of course, this is my opinion as it is not imposed.

You can do it, but it's not pretty:

#include <iostream>

class A {
    int mvalue;
public:
    A(int value) : mvalue(value) {}
    int value() { return mvalue; }
};

class B {
    // TODO: hack that respects alignment of A.. maybe C++14's alignof?
    char _hack[sizeof(A[3])];
    A* marr;
public:
    B() : marr(reinterpret_cast<A*>(_hack)) {
        new (&marr[0]) A(5);
        new (&marr[1]) A(6);
        new (&marr[2]) A(7);
    }

    A* arr() { return marr; }
};

int main(int argc, char** argv) {
    B b;
    A* arr = b.arr();
    std::cout << arr[0].value() << " " << arr[1].value() << " " << arr[2].value() << "\n";
    return 0;
}

If you put this in your code, I hope you have a VERY good reason.

In JUnit 4, another option for you may be to create an annotation to denote that the test needs to meet your custom criteria, then extend the default runner with your own and using reflection, base your decision on the custom criteria. It may look something like this:

public class CustomRunner extends BlockJUnit4ClassRunner {
    public CTRunner(Class<?> klass) throws initializationError {
        super(klass);
    }

    @Override
    protected boolean isIgnored(FrameworkMethod child) {
        if(shouldIgnore()) {
            return true;
        }
        return super.isIgnored(child);
    }

    private boolean shouldIgnore(class) {
        /* some custom criteria */
    }
}

There is an important difference between std::min, std::max and fmin and fmax.

std::min(-0.0,0.0) = -0.0
std::max(-0.0,0.0) = -0.0

whereas

fmin(-0.0, 0.0) = -0.0
fmax(-0.0, 0.0) =  0.0

So std::min is not a 1-1 substitute for fmin. The functions std::min and std::max are not commutative. To get the same result with doubles with fmin and fmax one should swap the arguments

fmin(-0.0, 0.0) = std::min(-0.0,  0.0)
fmax(-0.0, 0.0) = std::max( 0.0, -0.0)

But as far as I can tell all these functions are implementation defined anyway in this case so to be 100% sure you have to test how they are implemented.

There is another important difference. For x ! = NaN:

std::max(Nan,x) = NaN
std::max(x,NaN) = x
std::min(Nan,x) = NaN
std::min(x,NaN) = x

whereas

fmax(Nan,x) = x
fmax(x,NaN) = x
fmin(Nan,x) = x
fmin(x,NaN) = x

fmax can be emulated with the following code

double myfmax(double x, double y)
{
   // z > nan for z != nan is required by C the standard
   int xnan = isnan(x), ynan = isnan(y);
   if(xnan || ynan) {
        if(xnan && !ynan) return y;
        if(!xnan && ynan) return x;
        return x;
   }
   // +0 > -0 is preferred by C the standard 
   if(x==0 && y==0) {
       int xs = signbit(x), ys = signbit(y);
       if(xs && !ys) return y;
       if(!xs && ys) return x;
       return x;
   }
   return std::max(x,y);
}

This shows that std::max is a subset of fmax.

Looking at the assembly shows that Clang uses builtin code for fmax and fmin whereas GCC calls them from a math library. The assembly for clang for fmax with -O3 is

movapd  xmm2, xmm0
cmpunordsd      xmm2, xmm2
movapd  xmm3, xmm2
andpd   xmm3, xmm1
maxsd   xmm1, xmm0
andnpd  xmm2, xmm1
orpd    xmm2, xmm3
movapd  xmm0, xmm2

whereas for std::max(double, double) it is simply

maxsd   xmm0, xmm1

However, for GCC and Clang using -Ofast fmax becomes simply

maxsd   xmm0, xmm1

So this shows once again that std::max is a subset of fmax and that when you use a looser floating point model which does not have nan or signed zero then fmax and std::max are the same. The same argument obviously applies to fmin and std::min.

Named pipes and sockets are not functionally equivalent; sockets provide more features (they are bidirectional, for a start).

We cannot tell you which will perform better, but I strongly suspect it doesn't matter.

Unix domain sockets will do pretty much what tcp sockets will, but only on the local machine and with (perhaps a bit) lower overhead.

If a Unix socket isn't fast enough and you're transferring a lot of data, consider using shared memory between your client and server (which is a LOT more complicated to set up).

Unix and NT both have "Named pipes" but they are totally different in feature set.

CNAME'ing a root record is technically not against RFC, but does have limitations meaning it is a practice that is not recommended.

Normally your root record will have multiple entries. Say, 3 for your name servers and then one for an IP address.

Per RFC:

If a CNAME RR is present at a node, no other data should be present;

And Per IETF 'Common DNS Operational and Configuration Errors' Document:

This is often attempted by inexperienced administrators as an obvious way to allow your domain name to also be a host. However, DNS servers like BIND will see the CNAME and refuse to add any other resources for that name. Since no other records are allowed to coexist with a CNAME, the NS entries are ignored. Therefore all the hosts in the podunk.xx domain are ignored as well!

References:

• http://tools.ietf.org/html/rfc1912 section '2.4 CNAME Records'
• http://www.faqs.org/rfcs/rfc1034.html section '3.6.2. Aliases and canonical names'

SVN seems to handle binary deltas more efficiently than Git.

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

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

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

Initializing the contents of a list like that isn't really what lists are for. Lists are designed to hold objects. If you want to map particular numbers to particular objects, consider using a key-value pair structure like a hash table or dictionary instead of a list.

if you are just getting a single value out of either (not in a loop) then both do bounds checking (you're in managed code remember) it's just the list does it twice. See the notes later for why this is likely not a big deal.

If you are using your own for(int int i = 0; i < x.[Length/Count];i++) then the key difference is as follows:

• Array:
  • bounds checking is removed
• Lists
  • bounds checking is performed

If you are using foreach then the key difference is as follows:

• Array:
  • no object is allocated to manage the iteration
  • bounds checking is removed
• List via a variable known to be List.
  • the iteration management variable is stack allocated
  • bounds checking is performed
• List via a variable known to be IList.
  • the iteration management variable is heap allocated
  • bounds checking is performed also Lists values may not be altered during the foreach whereas the array's can be.

The bounds checking is often no big deal (especially if you are on a cpu with a deep pipeline and branch prediction - the norm for most these days) but only your own profiling can tell you if that is an issue. If you are in parts of your code where you are avoiding heap allocations (good examples are libraries or in hashcode implementations) then ensuring the variable is typed as List not IList will avoid that pitfall. As always profile if it matters.

You could just use normal Python argument passing syntax to specify your crontab. For example, suppose we define an Event class as below:

from datetime import datetime, timedelta
import time

# Some utility classes / functions first
class AllMatch(set):
    """Universal set - match everything"""
    def __contains__(self, item): return True

allMatch = AllMatch()

def conv_to_set(obj):  # Allow single integer to be provided
    if isinstance(obj, (int,long)):
        return set([obj])  # Single item
    if not isinstance(obj, set):
        obj = set(obj)
    return obj

# The actual Event class
class Event(object):
    def __init__(self, action, min=allMatch, hour=allMatch, 
                       day=allMatch, month=allMatch, dow=allMatch, 
                       args=(), kwargs={}):
        self.mins = conv_to_set(min)
        self.hours= conv_to_set(hour)
        self.days = conv_to_set(day)
        self.months = conv_to_set(month)
        self.dow = conv_to_set(dow)
        self.action = action
        self.args = args
        self.kwargs = kwargs

    def matchtime(self, t):
        """Return True if this event should trigger at the specified datetime"""
        return ((t.minute     in self.mins) and
                (t.hour       in self.hours) and
                (t.day        in self.days) and
                (t.month      in self.months) and
                (t.weekday()  in self.dow))

    def check(self, t):
        if self.matchtime(t):
            self.action(*self.args, **self.kwargs)

(Note: Not thoroughly tested)

Then your CronTab can be specified in normal python syntax as:

c = CronTab(
  Event(perform_backup, 0, 2, dow=6 ),
  Event(purge_temps, 0, range(9,18,2), dow=range(0,5))
)

This way you get the full power of Python's argument mechanics (mixing positional and keyword args, and can use symbolic names for names of weeks and months)

The CronTab class would be defined as simply sleeping in minute increments, and calling check() on each event. (There are probably some subtleties with daylight savings time / timezones to be wary of though). Here's a quick implementation:

class CronTab(object):
    def __init__(self, *events):
        self.events = events

    def run(self):
        t=datetime(*datetime.now().timetuple()[:5])
        while 1:
            for e in self.events:
                e.check(t)

            t += timedelta(minutes=1)
            while datetime.now() < t:
                time.sleep((t - datetime.now()).seconds)

A few things to note: Python's weekdays / months are zero indexed (unlike cron), and that range excludes the last element, hence syntax like "1-5" becomes range(0,5) - ie [0,1,2,3,4]. If you prefer cron syntax, parsing it shouldn't be too difficult however.

AlgoKit

I wrote an open source library called AlgoKit, available via NuGet. It contains:

• Implicit d-ary heaps (ArrayHeap),
• Binomial heaps,
• Pairing heaps.

The code has been extensively tested. I definitely recommend you to give it a try.

Example

var comparer = Comparer<int>.Default;
var heap = new PairingHeap<int, string>(comparer);

heap.Add(3, "your");
heap.Add(5, "of");
heap.Add(7, "disturbing.");
heap.Add(2, "find");
heap.Add(1, "I");
heap.Add(6, "faith");
heap.Add(4, "lack");

while (!heap.IsEmpty)
    Console.WriteLine(heap.Pop().Value);

Why those three heaps?

The optimal choice of implementation is strongly input-dependent — as Larkin, Sen, and Tarjan show in A back-to-basics empirical study of priority queues, arXiv:1403.0252v1 [cs.DS]. They tested implicit d-ary heaps, pairing heaps, Fibonacci heaps, binomial heaps, explicit d-ary heaps, rank-pairing heaps, quake heaps, violation heaps, rank-relaxed weak heaps, and strict Fibonacci heaps.

AlgoKit features three types of heaps that appeared to be most efficient among those tested.

Hint on choice

For a relatively small number of elements, you would likely be interested in using implicit heaps, especially quaternary heaps (implicit 4-ary). In case of operating on larger heap sizes, amortized structures like binomial heaps and pairing heaps should perform better.

Just had a similar problem, except i needed a NodeList and not a Document, here's what I came up with. It's mostly the same solution as before, augmented to get the root element down as a NodeList and using erickson's suggestion of using an InputSource instead for character encoding issues.

private String DOC_ROOT="root";
String xml=getXmlString();
Document xmlDoc=loadXMLFrom(xml);
Element template=xmlDoc.getDocumentElement();
NodeList nodes=xmlDoc.getElementsByTagName(DOC_ROOT);

public static Document loadXMLFrom(String xml) throws Exception {
        InputSource is= new InputSource(new StringReader(xml));
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setNamespaceAware(true);
        DocumentBuilder builder = null;
        builder = factory.newDocumentBuilder();
        Document doc = builder.parse(is);
        return doc;
    }

to select records for the last 7 days

WHERE Created_Date >= DATEADD(day, -7, GETDATE())

to select records for the current week

SET DATEFIRST 1 -- Define beginning of week as Monday
SELECT * FROM
WHERE CreatedDate >= DATEADD(day, 1 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE())) 
  AND CreatedDate <  DATEADD(day, 8 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE()))

if you want to select records for last week instead of the last 7 days

SET DATEFIRST 1 -- Define beginning of week as Monday
SELECT * FROM  
WHERE CreatedDate >= DATEADD(day, -(DATEPART(dw, GETDATE()) + 6), CONVERT(DATE, GETDATE())) 
  AND CreatedDate <  DATEADD(day, 1 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE()))

From MDN by setAttribute():

To set the value of a Boolean attribute, such as disabled, you can specify any value. An empty string or the name of the attribute are recommended values. All that matters is that if the attribute is present at all, regardless of its actual value, its value is considered to be true. The absence of the attribute means its value is false. By setting the value of the disabled attribute to the empty string (""), we are setting disabled to true, which results in the button being disabled.

Link to MDN

Solution

• I mean that in XHTML Strict is right disabled="disabled",
• and in HTML5 is only disabled, like <input name="myinput" disabled>
• In javascript, I set the value to true via e.disabled = true;
  or to "" via setAttribute( "disabled", "" );

Test in Chrome

var f = document.querySelectorAll( "label.disabled input" );
for( var i = 0; i < f.length; i++ )
{
    // Reference
    var e = f[ i ];

    // Actions
    e.setAttribute( "disabled", false|null|undefined|""|0|"disabled" );
    /*
        <input disabled="false"|"null"|"undefined"|empty|"0"|"disabled">
        e.getAttribute( "disabled" ) === "false"|"null"|"undefined"|""|"0"|"disabled"
        e.disabled === true
    */
    
    e.removeAttribute( "disabled" );
    /*
        <input>
        e.getAttribute( "disabled" ) === null
        e.disabled === false
    */

    e.disabled = false|null|undefined|""|0;
    /*
        <input>
        e.getAttribute( "disabled" ) === null|null|null|null|null
        e.disabled === false
    */

    e.disabled = true|" "|"disabled"|1;
    /*
        <input disabled>
        e.getAttribute( "disabled" ) === ""|""|""|""
        e.disabled === true
    */
}

I had this problem and couldn't solve it in Java code. The problem was with my xml.

I was trying to add a textView to a container, but had wrapped the textView inside a LinearLayout.

This was the original xml file:

<?xml version="1.0" encoding="utf-8"?>_x000D_
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"_x000D_
    android:orientation="vertical"_x000D_
    android:layout_width="match_parent"_x000D_
    android:layout_height="match_parent">_x000D_
    _x000D_
    <TextView xmlns:android="http://schemas.android.com/apk/res/android"_x000D_
        android:id="@android:id/text1"_x000D_
        android:layout_width="match_parent"_x000D_
        android:layout_height="wrap_content"_x000D_
        android:textAppearance="?android:attr/textAppearanceListItemSmall"_x000D_
        android:gravity="center_vertical"_x000D_
        android:paddingLeft="16dp"_x000D_
        android:paddingRight="16dp"_x000D_
        android:textColor="#fff"_x000D_
        android:background="?android:attr/activatedBackgroundIndicator"_x000D_
        android:minHeight="?android:attr/listPreferredItemHeightSmall"/>_x000D_
_x000D_
</LinearLayout>

Now with the LinearLayout removed:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"_x000D_
        android:id="@android:id/text1"_x000D_
        android:layout_width="match_parent"_x000D_
        android:layout_height="wrap_content"_x000D_
        android:textAppearance="?android:attr/textAppearanceListItemSmall"_x000D_
        android:gravity="center_vertical"_x000D_
        android:paddingLeft="16dp"_x000D_
        android:paddingRight="16dp"_x000D_
        android:textColor="#fff"_x000D_
        android:background="?android:attr/activatedBackgroundIndicator"_x000D_
        android:minHeight="?android:attr/listPreferredItemHeightSmall"/>

This didn't seem like much to me but it did the trick, and I didn't change my Java code at all. It was all in the xml.

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

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

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

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

As far as I know, can't you just make it abstract?

class parent {
public:
  virtual void handle_event(int something) const = 0 {
    // boring default code
  }
};

I thought I read on www.parashift.com that you can actually implement an abstract method. Which makes sense to me personally, the only thing it does is force subclasses to implement it, no one said anything about it not being allowed to have an implementation itself.

This is an old question. Not sure when support became more broad, but getAllResponseHeaders() and getResponseHeader() appear to now be fairly standard: http://www.w3schools.com/xml/dom_http.asp

I was facing this similiar problem and did not want to use header() to redirect to another page.

Solution:

Use $_POST = array(); to reset the $_POST array at the top of the form, along with the code used to process the form.

The error or success messages can be conditionally added after the form. Hope this helps :)

Currently the method to add the listener to the map would be

map.addListener('click', function(e) {
    placeMarker(e.latLng, map);
});

And not

google.maps.event.addListener(map, 'click', function(e) {
    placeMarker(e.latLng, map);
});

Reference

For Oracle, John's solution using instr() function works. Here's slightly different solution that worked - SELECT id FROM table1 WHERE id IN (1, 20, 45, 60) ORDER BY instr('1, 20, 45, 60', id)

its possible using syntax:

RUNAS [/profile] [/env] [/netonly] /user:user Program

Key :
/profile Option to load the user's profile (registry)
/env Use current environment instead of user's.
/netonly Use the credentials specified only for remote connections.
/user Username in form USER@DOMAIN or DOMAIN\USER
(USER@DOMAIN is not compatible with /netonly)
Program The command to execute

example :

runas /env /user:domain\Administrator <program.exe/command you want to execute>

Use the java.lang.reflect.Method object and call invoke

Just write

System.Diagnostics.Process.Start(@"file path");

example

System.Diagnostics.Process.Start(@"C:\foo.jpg");
System.Diagnostics.Process.Start(@"C:\foo.doc");
System.Diagnostics.Process.Start(@"C:\foo.dxf");
...

And shell will run associated program reading it from the registry, like usual double click does.

If you're making a dictionary only to make a list of tuples, as creating dicts like you are may be a pain, you might look into using zip()

Its especialy useful if you've got one heading, and multiple rows. For instance if I assume that you want Olympics stats for countries:

headers = ['Capital', 'Food', 'Year']
countries = [
    ['London', 'Fish & Chips', '2012'],
    ['Beijing', 'Noodles', '2008'],
]

for olympics in countries:
    print zip(headers, olympics)

gives

[('Capital', 'London'), ('Food', 'Fish & Chips'), ('Year', '2012')]
[('Capital', 'Beijing'), ('Food', 'Noodles'), ('Year', '2008')]

Don't know if thats the end goal, and my be off topic, but it could be something to keep in mind.

Works on all browsers, this is all you need.

  function commaSeparateNumber(val){
    while (/(\d+)(\d{3})/.test(val.toString())){
      val = val.toString().replace(/(\d+)(\d{3})/, '$1'+','+'$2');
    }
    return val;
  }

Wrote this to be compact, and to the point, thanks to regex. This is straight JS, but you can use it in your jQuery like so:

$('#elementID').html(commaSeparateNumber(1234567890));

or

$('#inputID').val(commaSeparateNumber(1234567890));

Another option is to use an array, e.g. void method(SomeClass[] v) { v[0] = ...; } but 1) the array must be initialized before method invoked, 2) still one cannot implement e.g. swap method in this way... This way is used in JDK, e.g. in java.util.concurrent.atomic.AtomicMarkableReference.get(boolean[]).

Preconditions: adb and wireshark is installed on your computer and you have a rooted android device.

1. Download tcpdump to ~/Downloads
2. adb push ~/Downloads/tcpdump /sdcard/
3. adb shell
4. su root
5. mv /sdcard/tcpdump /data/local/
6. cd /data/local/
7. chmod +x tcpdump
8. ./tcpdump -vv -i any -s 0 -w /sdcard/dump.pcap
9. CTRL+C after you've captured enough packets.
10. exit
11. exit
12. adb pull /sdcard/dump.pcap ~/Downloads/

Now you can open the pcap file using Wireshark.

Ok so here's how I figured this out. It all has to do with CORS policy. Before the POST request, Chrome was doing a preflight OPTIONS request, which should be handled and acknowledged by the server prior to the actual request. Now this is really not what I wanted for such a simple server. Hence, resetting the headers client side prevents the preflight:

app.config(function ($httpProvider) {
  $httpProvider.defaults.headers.common = {};
  $httpProvider.defaults.headers.post = {};
  $httpProvider.defaults.headers.put = {};
  $httpProvider.defaults.headers.patch = {};
});

The browser will now send a POST directly. Hope this helps a lot of folks out there... My real problem was not understanding CORS enough.

Link to a great explanation: http://www.html5rocks.com/en/tutorials/cors/

Kudos to this answer for showing me the way.

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// saving an NSString
[prefs setObject:@"TextToSave" forKey:@"keyToLookupString"];

// saving an NSInteger
[prefs setInteger:42 forKey:@"integerKey"];

// saving a Double
[prefs setDouble:3.1415 forKey:@"doubleKey"];

// saving a Float
[prefs setFloat:1.2345678 forKey:@"floatKey"];

// This is suggested to synch prefs, but is not needed (I didn't put it in my tut)
[prefs synchronize];

Retrieving

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// getting an NSString
NSString *myString = [prefs stringForKey:@"keyToLookupString"];

// getting an NSInteger
NSInteger myInt = [prefs integerForKey:@"integerKey"];

// getting an Float
float myFloat = [prefs floatForKey:@"floatKey"];

ok just so you know there is a program out there that's called DroidDraw. It can help you draw objects and try them one on top of the other. I tried your solution but I had animation under the smaller image so that didn't work. But then I tried to place one image in a relative layout that's suppose to be under first and then on top of that I drew the other image that is suppose to overlay and everything worked great. So RelativeLayout, DroidDraw and you are good to go :) Simple, no any kind of jiggery pockery :) and here is a bit of code for ya:

The logo is going to be on top of shazam background image.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="@+id/widget30"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<ImageView
android:id="@+id/widget39"
android:layout_width="219px"
android:layout_height="225px"
android:src="@drawable/shazam_bkgd"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
>
</ImageView>
<ImageView
android:id="@+id/widget37"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/shazam_logo"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
>
</ImageView>
</RelativeLayout>

If there is space between the letters of the font, you need to use quote.

font-family:"Calibri (Body)";

JLS

JLS 7 3.10.5 defines it and gives a practical example:

Moreover, a string literal always refers to the same instance of class String. This is because string literals - or, more generally, strings that are the values of constant expressions (§15.28) - are "interned" so as to share unique instances, using the method String.intern.

Example 3.10.5-1. String Literals

The program consisting of the compilation unit (§7.3):

package testPackage;
class Test {
    public static void main(String[] args) {
        String hello = "Hello", lo = "lo";
        System.out.print((hello == "Hello") + " ");
        System.out.print((Other.hello == hello) + " ");
        System.out.print((other.Other.hello == hello) + " ");
        System.out.print((hello == ("Hel"+"lo")) + " ");
        System.out.print((hello == ("Hel"+lo)) + " ");
        System.out.println(hello == ("Hel"+lo).intern());
    }
}
class Other { static String hello = "Hello"; }

and the compilation unit:

package other;
public class Other { public static String hello = "Hello"; }

produces the output:

true true true true false true

JVMS

JVMS 7 5.1 says says that interning is implemented magically and efficiently with a dedicated CONSTANT_String_info struct (unlike most other objects which have more generic representations):

A string literal is a reference to an instance of class String, and is derived from a CONSTANT_String_info structure (§4.4.3) in the binary representation of a class or interface. The CONSTANT_String_info structure gives the sequence of Unicode code points constituting the string literal.

The Java programming language requires that identical string literals (that is, literals that contain the same sequence of code points) must refer to the same instance of class String (JLS §3.10.5). In addition, if the method String.intern is called on any string, the result is a reference to the same class instance that would be returned if that string appeared as a literal. Thus, the following expression must have the value true:

("a" + "b" + "c").intern() == "abc"

To derive a string literal, the Java Virtual Machine examines the sequence of code points given by the CONSTANT_String_info structure.

• If the method String.intern has previously been called on an instance of class String containing a sequence of Unicode code points identical to that given by the CONSTANT_String_info structure, then the result of string literal derivation is a reference to that same instance of class String.

• Otherwise, a new instance of class String is created containing the sequence of Unicode code points given by the CONSTANT_String_info structure; a reference to that class instance is the result of string literal derivation. Finally, the intern method of the new String instance is invoked.

Bytecode

Let's decompile some OpenJDK 7 bytecode to see interning in action.

If we decompile:

public class StringPool {
    public static void main(String[] args) {
        String a = "abc";
        String b = "abc";
        String c = new String("abc");
        System.out.println(a);
        System.out.println(b);
        System.out.println(a == c);
    }
}

we have on the constant pool:

#2 = String             #32   // abc
[...]
#32 = Utf8               abc

and main:

 0: ldc           #2          // String abc
 2: astore_1
 3: ldc           #2          // String abc
 5: astore_2
 6: new           #3          // class java/lang/String
 9: dup
10: ldc           #2          // String abc
12: invokespecial #4          // Method java/lang/String."<init>":(Ljava/lang/String;)V
15: astore_3
16: getstatic     #5          // Field java/lang/System.out:Ljava/io/PrintStream;
19: aload_1
20: invokevirtual #6          // Method java/io/PrintStream.println:(Ljava/lang/String;)V
23: getstatic     #5          // Field java/lang/System.out:Ljava/io/PrintStream;
26: aload_2
27: invokevirtual #6          // Method java/io/PrintStream.println:(Ljava/lang/String;)V
30: getstatic     #5          // Field java/lang/System.out:Ljava/io/PrintStream;
33: aload_1
34: aload_3
35: if_acmpne     42
38: iconst_1
39: goto          43
42: iconst_0
43: invokevirtual #7          // Method java/io/PrintStream.println:(Z)V

Note how:

• 0 and 3: the same ldc #2 constant is loaded (the literals)
• 12: a new string instance is created (with #2 as argument)
• 35: a and c are compared as regular objects with if_acmpne

The representation of constant strings is quite magic on the bytecode:

• it has a dedicated CONSTANT_String_info structure, unlike regular objects (e.g. new String)
• the struct points to a CONSTANT_Utf8_info Structure that contains the data. That is the only necessary data to represent the string.

and the JVMS quote above seems to say that whenever the Utf8 pointed to is the same, then identical instances are loaded by ldc.

I have done similar tests for fields, and:

• static final String s = "abc" points to the constant table through the ConstantValue Attribute
• non-final fields don't have that attribute, but can still be initialized with ldc

Conclusion: there is direct bytecode support for the string pool, and the memory representation is efficient.

Bonus: compare that to the Integer pool, which does not have direct bytecode support (i.e. no CONSTANT_String_info analogue).

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

You can see the working version here.

Try this, replacing .myClassName with the actual name of the class (but keep the period at the beginning).

$('.myClassName').each(function() {
    alert( this.id );
});

So if the class is "test", you'd do $('.test').each(func....

This is the specific form of .each() that iterates over a jQuery object.

The form you were using iterates over any type of collection. So you were essentially iterating over an array of characters t,e,s,t.

Using that form of $.each(), you would need to do it like this:

$.each($('.myClassName'), function() {
    alert( this.id );
});

...which will have the same result as the example above.

Default-Values are only considered for parameters NOT given to the function.

So given a function

procedure foo( bar1 IN number DEFAULT 3,
     bar2 IN number DEFAULT 5,
     bar3 IN number DEFAULT 8 );

if you call this procedure with no arguments then it will behave as if called with

foo( bar1 => 3,
     bar2 => 5,
     bar3 => 8 );

but 'NULL' is still a parameter.

foo( 4,
     bar3 => NULL );

This will then act like

foo( bar1 => 4,
     bar2 => 5,
     bar3 => Null );

( oracle allows you to either give the parameter in order they are specified in the procedure, specified by name, or first in order and then by name )

one way to treat NULL the same as a default value would be to default the value to NULL

procedure foo( bar1 IN number DEFAULT NULL,
     bar2 IN number DEFAULT NULL,
     bar3 IN number DEFAULT NULL );

and using a variable with the desired value then

procedure foo( bar1 IN number DEFAULT NULL,
     bar2 IN number DEFAULT NULL,
     bar3 IN number DEFAULT NULL )
AS
     v_bar1    number := NVL( bar1, 3);
     v_bar2    number := NVL( bar2, 5);
     v_bar3    number := NVL( bar3, 8);

Here's a simple scraper I created in c# to get streaming quote data printed out to a console. It should be easily converted to java. Based on the following post:

I prefer this solution using the csv module from the standard library and the with statement to avoid leaving the file open.

The key point is using 'a' for appending when you open the file.

import csv   
fields=['first','second','third']
with open(r'name', 'a') as f:
    writer = csv.writer(f)
    writer.writerow(fields)

If you are using Python 2.7 you may experience superfluous new lines in Windows. You can try to avoid them using 'ab' instead of 'a' this will, however, cause you TypeError: a bytes-like object is required, not 'str' in python and CSV in Python 3.6. Adding the newline='', as Natacha suggests, will cause you a backward incompatibility between Python 2 and 3.

Actually this is not really the answer of the question, but this is a better way to do it.

I suggest you to use connect/express as http server, since they save you a lot of time. You obviously don't want to reinvent the wheel. In your case session management is much easier with connect/express.

Beside that for authentication I suggest you to use everyauth. Which supports a lot of authentication strategies. Awesome for rapid development.

All this can be easily down with some copy pasting from their documentation!

If you have a pd.Series object x with index named 'Gene', you can use reset_index and supply the name argument:

df = x.reset_index(name='count')

Here's a demo:

x = pd.Series([2, 7, 1], index=['Ezh2', 'Hmgb', 'Irf1'])
x.index.name = 'Gene'

df = x.reset_index(name='count')

print(df)

   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

update table_name set (col1,col2,col3) values(col1,col2,col);

Is not standard SQL and not working you got to use this as Gordon Linoff said:

update table
    set col1 = expr1,
        col2 = expr2,
        . . .
        coln = exprn
    where some condition

For relative imports you have to:

• a) use relative name

• b) provide anchor explicitly

  importlib.import_module('.c', 'a.b')
  

Of course, you could also just do absolute import instead:

importlib.import_module('a.b.c')

You can do this with the following:

int counter = 0;
String sql = "SELECT projectName,Owner " + "FROM Project WHERE Owner= ?";
PreparedStatement prep = conn.prepareStatement(sql);
prep.setString(1, "");
ResultSet rs = prep.executeQuery();
while (rs.next()) {
    counter++;
}
System.out.println(counter);

This will give you the no of rows where the column value is null or blank.

You won't be able to make an ajax call to http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml from a file deployed at http://run.jsbin.com due to the same-origin policy.

As the source (aka origin) page and the target URL are at different domains (run.jsbin.com and www.ecb.europa.eu), your code is actually attempting to make a Cross-domain (CORS) request, not an ordinary GET.

In a few words, the same-origin policy says that browsers should only allow ajax calls to services at the same domain of the HTML page.

Example:

A page at http://www.example.com/myPage.html can only directly request services that are at http://www.example.com, like http://www.example.com/api/myService. If the service is hosted at another domain (say http://www.ok.com/api/myService), the browser won't make the call directly (as you'd expect). Instead, it will try to make a CORS request.

To put it shortly, to perform a (CORS) request* across different domains, your browser:

• Will include an Origin header in the original request (with the page's domain as value) and perform it as usual; and then
• Only if the server response to that request contains the adequate headers (Access-Control-Allow-Origin is one of them) allowing the CORS request, the browse will complete the call (almost** exactly the way it would if the HTML page was at the same domain).
  • If the expected headers don't come, the browser simply gives up (like it did to you).

_{* The above depicts the steps in a simple request, such as a regular GET with no fancy headers. If the request is not simple (like a POST with application/json as content type), the browser will hold it a moment, and, before fulfilling it, will first send an OPTIONS request to the target URL. Like above, it only will continue if the response to this OPTIONS request contains the CORS headers. This OPTIONS call is known as preflight request.
** I'm saying almost because there are other differences between regular calls and CORS calls. An important one is that some headers, even if present in the response, will not be picked up by the browser if they aren't included in the Access-Control-Expose-Headers header.}

How to fix it?

Was it just a typo? Sometimes the JavaScript code has just a typo in the target domain. Have you checked? If the page is at www.example.com it will only make regular calls to www.example.com! Other URLs, such as api.example.com or even example.com or www.example.com:8080 are considered different domains by the browser! Yes, if the port is different, then it is a different domain!

Add the headers. The simplest way to enable CORS is by adding the necessary headers (as Access-Control-Allow-Origin) to the server's responses. (Each server/language has a way to do that - check some solutions here.)

Last resort: If you don't have server-side access to the service, you can also mirror it (through tools such as reverse proxies), and include all the necessary headers there.

The root cause of this problem has to do with user authentication versions. For each database user, multiple password verifiers are kept in the database. Typically when you upgrade your database, a new password verifier will be added to the list, a stronger one. The following query shows the password verifier versions that are available for each user. For example:

SQL> SELECT PASSWORD_VERSIONS FROM DBA_USERS WHERE USERNAME='SCOTT';

PASSWORD_VERSIONS
-----------------
11G 12C

When upgrading to a newer driver you can use a newer version of the verifier because the driver and server negotiate the strongest possible verifier to to be used. This newer version of the verifier will be more secure and will involve generating larger random numbers or using more complex hashing functions which can explain why you see issues while establishing JDBC connections. As mentioned by other responses using /dev/urandom normally resolves these issues. You can also decide to downgrade your password verifier and make the newer driver use the same older password verifier that your previous driver was using. For example if you want to use the 10G password verifier (for testing purposes only), first you need to make sure it's available for your user. Set SQLNET.ALLOWED_LOGON_VERSION_SERVER=8 in sqlnet.ora on the server. Then:

SQL> alter user scott identified by "tiger";

User altered.

SQL> SELECT PASSWORD_VERSIONS FROM DBA_USERS WHERE USERNAME='SCOTT';
PASSWORD_VERSIONS
-----------------
10G 11G 12C

Then you can force the JDBC thin driver to use the 10G verifier by setting this JDBC property oracle.jdbc.thinLogonCapability="o3". If you run into the error "ORA-28040: No matching authentication protocol" then that means your server is not allowing the 10G verifier to be used. If that's the case then you need to check your configuration again.

With ctypes, you can achieve the same thing with

>>> import ctypes
>>> a = (1,2,3)
>>> ctypes.addressof(a)
3077760748L

Documentation:

addressof(C instance) -> integer
Return the address of the C instance internal buffer

Note that in CPython, currently id(a) == ctypes.addressof(a), but ctypes.addressof should return the real address for each Python implementation, if

• ctypes is supported
• memory pointers are a valid notion.

Edit: added information about interpreter-independence of ctypes

It's called Hiding Fields

From the link above

Within a class, a field that has the same name as a field in the superclass hides the superclass's field, even if their types are different. Within the subclass, the field in the superclass cannot be referenced by its simple name. Instead, the field must be accessed through super, which is covered in the next section. Generally speaking, we don't recommend hiding fields as it makes code difficult to read.

In your situation, you can extract the desired data with:

a[:, -z]

"-z" is the logical negation of the boolean array "z". This is the same as:

a[:, logical_not(z)]

"pull-right" class may not be the right way because in uses "float: right" instead of text-align.

Checking the bootstrap 3 css file i found "text-right" class on line 457. This class should be the right way to align the text to the right.

Some code:

<div class="row">
    <div class="col-xs-12">
        <div class="text-right">
            <button type="button" class="btn btn-default">Default</button>
        </div>
    </div>
</div>

I was going through some details related to tuple and list, and what I understood is:

• Tuples are Heterogeneous collection data type
• Tuple has Fixed length (per tuple type)
• Tuple are Always finite

So for appending new item to a tuple, need to cast it to list, and do append() operation on it, then again cast it back to tuple.

But personally what I felt about the Question is, if Tuples are supposed to be finite, fixed length items and if we are using those data types in our application logics then there should not be a scenario to appending new items OR updating an item value in it. So instead of list of tuples it should be list of list itself, Am I right on this?

This could also be done using display: flex with only a few lines of code. Here is an example:

.container {
  width: 100px;
  height: 100px;
  display: flex;
  align-items: center;
}

Live Demo

Redis supports 5 data types. You need to know what type of value that a key maps to, as for each data type, the command to retrieve it is different.

Here are the commands to retrieve key value:

• if value is of type string -> GET <key>
• if value is of type hash -> HGETALL <key>
• if value is of type lists -> lrange <key> <start> <end>
• if value is of type sets -> smembers <key>
• if value is of type sorted sets -> ZRANGEBYSCORE <key> <min> <max>

Use the TYPE command to check the type of value a key is mapping to:

• type <key>

In my case I had deleted a class called "viewController" not realising it was selected with the storyboard's identity inspector (under 'Custom Class' up the top).

You just have to simply select the correct class for the view controller in your identity inspector's Custom Class field or add a new class to your project and select that one as your Custom Class.

Worked for me!

You can simply convert it in a comment..

Or you can do this:

br {
display: none;
}

But if you do not want it why are you puting that there?

Macbook: ?J or fnF1 does the same.
Also, use the one from the editor definition as explained above.

One way is that In case of Session Expire, in every action you have to check its session and if it is null then redirect to Login page.

But this is very hectic method To over come this you need to create your own ActionFilterAttribute which will do this, you just need to add this attribute in every action method.

Here is the Class which overrides ActionFilterAttribute.

public class SessionExpireFilterAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpContext ctx = HttpContext.Current;

            // check if session is supported
            CurrentCustomer objCurrentCustomer = new CurrentCustomer();
            objCurrentCustomer = ((CurrentCustomer)SessionStore.GetSessionValue(SessionStore.Customer));
            if (objCurrentCustomer == null)
            {
                // check if a new session id was generated
                filterContext.Result = new RedirectResult("~/Users/Login");
                return;
            }

            base.OnActionExecuting(filterContext);
        }
    }

Then in action just add this attribute like so:

[SessionExpire]
public ActionResult Index()
{
     return Index();
}

This will do you work.

I really wanted to comment, not answer. But just to be precise, OSX is not based on BSD, it is an evolution of NeXTStep. The NeXTStep OS utilizes the Mach kernel developed by CMU. It was originally designed as a MicroKernel, but due to performance constraints, they eventually decided they needed to include the Unix portion of the API into the kernel itself and so a BSD-compatible "server" (originally intended to process requests for BSD-compatible kernel messages) was moved into the kernel, making it a Monolithic kernel. It may be BSD compatible in the programming API, but it is NOT BSD.

The rest of the OS involved ObjectiveC (under arrangements between Stepstone and Richard Stallman of GNU/GCC) with a GUI based on a technology called "Display Postscript" ... sort of like an X Server, but with postscript commands. OS X changed Display Postscript to Display PDF, and increased the general hardware requirements 1000 fold (NeXT could run in 8-16MB, now you need GB).

Due to the close marriage of GCC and Objective C and NeXT, your best bet at running XCode natively under Linux would be to do a port (if you can get ahold of the source - good luck) utilizing the GNUStep libraries. Originally designed for NextStep and then OpenStep compatibility, I've heard they are now more-or-less Cocoa compatible, but I've not played with any of it in almost 2 decades. Of course that only gets you as far as ObjC, not Swift, and I don't know if Apple is going to OpenSource it.

I suggest you use http-request, so that even redirects are managed.

var http = require('http-request');
var options = {url: 'http://localhost/foo.pdf'};
http.get(options, '/path/to/foo.pdf', function (error, result) {
    if (error) {
        console.error(error);
    } else {
        console.log('File downloaded at: ' + result.file);
    }
});

Declare the a element as display: inline-block and drop the width and height from the li element.

Alternatively, apply a float: left to the li element and use display: block on the a element. This is a bit more cross browser compatible, as display: inline-block is not supported in Firefox <= 2 for example.

The first method allows you to have a dynamically centered list if you give the ul element a width of 100% (so that it spans from left to right edge) and then apply text-align: center.

Use line-height to control the text's Y-position inside the element.

enum builder class

public class XEnum
{
    private EnumBuilder enumBuilder;
    private int index;
    private AssemblyBuilder _ab;
    private AssemblyName _name;
    public XEnum(string enumname)
    {
        AppDomain currentDomain = AppDomain.CurrentDomain;
        _name = new AssemblyName("MyAssembly");
        _ab = currentDomain.DefineDynamicAssembly(
            _name, AssemblyBuilderAccess.RunAndSave);

        ModuleBuilder mb = _ab.DefineDynamicModule("MyModule");

        enumBuilder = mb.DefineEnum(enumname, TypeAttributes.Public, typeof(int));


    }
    /// <summary>

        return o1;

        return o1;
    }
}

create an object

string[] types = { "String", "Boolean", "Int32", "Enum", "Point", "Thickness", "long", "float" };
XEnum xe = new XEnum("Enum");
        xe.addRange(types);
        return xe.getEnum();

These will also redirect both:

yourcommand  &> /dev/null

yourcommand  >& /dev/null

though the bash manual says the first is preferred.

cat table |
  perl -ne '/\d+\s+(\d+)\s+(\S+)/ && print "".**int**(log($1)/log(2))."\t$2\n";' 

Not a big fan of the solutions provided (ie: multiple variables, helper classes, looping through 'possibly existing variables'). Below is a solution that instead uses an array as opposed to two separate variables. It's also easily extendable to handle multiple errors should you wish but for simplicity, I've kept it to one flash message:

Redirect with flash message array:

    return redirect('/admin/permissions')->with('flash_message', ['success','Updated Successfully','Permission "'. $permission->name .'" updated successfully!']);

Output based on array content:

@if(Session::has('flash_message'))
    <script type="text/javascript">
        jQuery(document).ready(function(){
            bootstrapNotify('{{session('flash_message')[0]}}','{{session('flash_message')[1]}}','{{session('flash_message')[2]}}');
        });
    </script>
@endif

Unrelated since you might have your own notification method/plugin - but just for clarity - bootstrapNotify is just to initiate bootstrap-notify from http://bootstrap-notify.remabledesigns.com/:

function bootstrapNotify(type,title = 'Notification',message) {
    switch (type) {
        case 'success':
            icon = "la-check-circle";
            break;
        case 'danger':
            icon = "la-times-circle";
            break;
        case 'warning':
            icon = "la-exclamation-circle";
    }

    $.notify({message: message, title : title, icon : "icon la "+ icon}, {type: type,allow_dismiss: true,newest_on_top: false,mouse_over: true,showProgressbar: false,spacing: 10,timer: 4000,placement: {from: "top",align: "right"},offset: {x: 30,y: 30},delay: 1000,z_index: 10000,animate: {enter: "animated bounce",exit: "animated fadeOut"}});
}

.cmd and .bat file execution is different because in a .cmd errorlevel variable it can change on a command that is affected by command extensions. That's about it really.

You can use an event listener to close the clip after it is played

import java.io.File;
import javax.sound.sampled.*;

public void play(File file) 
{
    try
    {
        final Clip clip = (Clip)AudioSystem.getLine(new Line.Info(Clip.class));

        clip.addLineListener(new LineListener()
        {
            @Override
            public void update(LineEvent event)
            {
                if (event.getType() == LineEvent.Type.STOP)
                    clip.close();
            }
        });

        clip.open(AudioSystem.getAudioInputStream(file));
        clip.start();
    }
    catch (Exception exc)
    {
        exc.printStackTrace(System.out);
    }
}

I'm afraid that you've put constraints on the set of solutions that, well, leave you with the null set.

Using :set textwidth=80 will fix all of the problems you mentioned except that you can't easily see the line limit coming up. If you :set ruler, you'll enable the x,y position display on the status bar, which you can use to see which column you're in.

Aside from that, I'm not sure what to tell you. It's a shame to lose the number column, fold column and splits just because you have to :set columns=80.

The dynamic SQL is a different scope to the outer, calling SQL: so @siteid is not recognised

You'll have to use a temp table/table variable outside of the dynamic SQL:

DECLARE @dbName nvarchar(128) = 'myDb'
DECLARE @siteId TABLE (siteid int)

INSERT @siteId
exec ('SELECT TOP 1 Id FROM ' + @dbName + '..myTbl')  

select * FROM @siteId

Note: TOP without an ORDER BY is meaningless. There is no natural, implied or intrinsic ordering to a table. Any order is only guaranteed by the outermost ORDER BY

While I commiserate with your concern about lacking this language feature, you're probably just going to want to use a normal for loop. And you'll probably be more okay with that than you think as you write more Go code.

I wrote this iter package — which is backed by a simple, idiomatic for loop that returns values over a chan int — in an attempt to improve on the design found in https://github.com/bradfitz/iter, which has been pointed out to have caching and performance issues, as well as a clever, but strange and unintuitive implementation. My own version operates the same way:

package main

import (
    "fmt"
    "github.com/drgrib/iter"
)

func main() {
    for i := range iter.N(10) {
        fmt.Println(i)
    }
}

However, benchmarking revealed that the use of a channel was a very expensive option. The comparison of the 3 methods, which can be run from iter_test.go in my package using

go test -bench=. -run=.

quantifies just how poor its performance is

BenchmarkForMany-4                   5000       329956 ns/op           0 B/op          0 allocs/op
BenchmarkDrgribIterMany-4               5    229904527 ns/op         195 B/op          1 allocs/op
BenchmarkBradfitzIterMany-4          5000       337952 ns/op           0 B/op          0 allocs/op

BenchmarkFor10-4                500000000         3.27 ns/op           0 B/op          0 allocs/op
BenchmarkDrgribIter10-4            500000      2907 ns/op             96 B/op          1 allocs/op
BenchmarkBradfitzIter10-4       100000000        12.1 ns/op            0 B/op          0 allocs/op

In the process, this benchmark also shows how the bradfitz solution underperforms in comparison to the built-in for clause for a loop size of 10.

In short, there appears to be no way discovered so far to duplicate the performance of the built-in for clause while providing a simple syntax for [0,n) like the one found in Python and Ruby.

Which is a shame because it would probably be easy for the Go team to add a simple rule to the compiler to change a line like

for i := range 10 {
    fmt.Println(i)
}

to the same machine code as for i := 0; i < 10; i++.

However, to be fair, after writing my own iter.N (but before benchmarking it), I went back through a recently written program to see all the places I could use it. There actually weren't many. There was only one spot, in a non-vital section of my code, where I could get by without the more complete, default for clause.

So while it may look like this is a huge disappointment for the language in principle, you may find — like I did — that you actually don't really need it in practice. Like Rob Pike is known to say for generics, you might not actually miss this feature as much as you think you will.

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

According to the w3 spec section 4.6.3 for XMLHttpRequest a user agent should honor the Set-Cookie header. So the answer is yes you should be able to.

Quotation:

If the user agent supports HTTP State Management it should persist, discard and send cookies (as received in the Set-Cookie response header, and sent in the Cookie header) as applicable.

You can create a custom JSONObjectReuqest and override the getParams method, or you can provide them in the constructor as a JSONObject to be put in the body of the request.

Like this (I edited your code):

JSONObject obj = new JSONObject();
obj.put("id", "1");
obj.put("name", "myname");

RequestQueue queue = MyVolley.getRequestQueue();
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST,SPHERE_URL,obj,
    new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
             System.out.println(response);
             hideProgressDialog();
        }
    },
    new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
             hideProgressDialog();
        }
    });
queue.add(jsObjRequest);

You can do it in a hackish way. Careful using the sqlcmd hack. If the data has double quotes or commas you will run into trouble.

You can use a simple script to do it properly:

Just in case someone encounters this on a QNAP system or any other system with OPKG as package manager:

You need to install git-http along with git. Like:

opkg install git-http

One should ask why you would want a public getter method for the password. Hibernate, or any other ORM framework, will do with a private getter method. For checking whether the password is correct, you can use

public boolean checkPassword(String password){
  return this.password.equals(anyHashingMethod(password));
}

just use a label tag, that way you can hide the input, and make it work through its related label https://developer.mozilla.org/fr/docs/Web/HTML/Element/Label

Use

item.Attributes["Name"].Value;

to get the value.

If you're using .NET, put Console.ReadLine() before the end of the program.

It will wait for <ENTER>.

You can use the Bean Comparator to sort on any property in your custom class.

}

I've been working on some Instagram extension for chrome last few days and I got this to workout:

First, you need to know that this can work if the user profile is public or you are logged in and you are following that user.

I am not sure why does it work like this, but probably some cookies are set when you log in that are checked on the backend while fetching private profiles.

Now I will share with you an ajax example but you can find other ones that suit you better if you are not using jquery.

Also, you can notice that we have two query_hash values for followers and followings and for other queries different ones.

let config = {
  followers: {
    hash: 'c76146de99bb02f6415203be841dd25a',
    path: 'edge_followed_by'
  },
  followings: {
    hash: 'd04b0a864b4b54837c0d870b0e77e076',
    path: 'edge_follow'
  }
};

The user ID you can get from https://www.instagram.com/user_name/?__a=1 as response.graphql.user.id

After is just response from first part of users that u are getting since the limit is 50 users per request:

let after = response.data.user[list].page_info.end_cursor

let data = {followers: [], followings: []};

function getFollows (user, list = 'followers', after = null) {
  $.get(`https://www.instagram.com/graphql/query/?query_hash=${config[list].hash}&variables=${encodeURIComponent(JSON.stringify({
    "id": user.id,
    "include_reel": true,
    "fetch_mutual": true,
    "first": 50,
    "after": after
  }))}`, function (response) {
    data[list].push(...response.data.user[config[list].path].edges);
    if (response.data.user[config[list].path].page_info.has_next_page) {
      setTimeout(function () {
        getFollows(user, list, response.data.user[config[list].path].page_info.end_cursor);
      }, 1000);
    } else if (list === 'followers') {
      getFollows(user, 'followings');
    } else {
      alert('DONE!');
      console.log(followers);
      console.log(followings);
    }
  });
}

You could probably use this off instagram website but I did not try, you would probably need some headers to match those from instagram page.

And if you need for those headers some additional data you could maybe find that within window._sharedData JSON that comes from backend with csrf token etc.

You can catch this by using:

let $script = JSON.parse(document.body.innerHTML.match(/<script type="text\/javascript">window\._sharedData = (.*)<\/script>/)[1].slice(0, -1));

Thats all from me!

Hope it helps you out!

    listen       80;
    server_name www.domain2.com;
    root /var/www/domain2;
}

Note, I have only included the relevant lines. Everything else looked okay but I just deleted it for clarity. To test it you might want to try serving a text file from each server first before actually serving php. That's why I left the 'root' directive in there.

TL:DR; return promises from you actions only when necessary, but DRY chaining the same actions.

For a long time I also though that returning actions contradicts the Vuex cycle of uni-directional data flow.

But, there are EDGE CASES where returning a promise from your actions might be "necessary".

Imagine a situation where an action can be triggered from 2 different components, and each handles the failure case differently. In that case, one would need to pass the caller component as a parameter to set different flags in the store.

Dumb example

Page where the user can edit the username in navbar and in /profile page (which contains the navbar). Both trigger an action "change username", which is asynchronous. If the promise fails, the page should only display an error in the component the user was trying to change the username from.

Of course it is a dumb example, but I don't see a way to solve this issue without duplicating code and making the same call in 2 different actions.

Here is a Plunker handling any situation above proposition do not handle.
By using $formatters and $parsers pipeline and avoiding type="number"

And here is the explanation of problems/solutions (also available in the Plunker) :

/*
 *
 * Limit input text for floating numbers.
 * It does not display characters and can limit the Float value to X numbers of integers and X numbers of decimals.
 * min and max attributes can be added. They can be Integers as well as Floating values.
 *
 * value needed    |    directive
 * ------------------------------------
 * 55              |    max-integer="2"
 * 55.55           |    max-integer="4" decimal="2" (decimals are substracted from total length. Same logic as database NUMBER type)
 *
 *
 * Input type="number" (HTML5)
 *
 * Browser compatibility for input type="number" :
 * Chrome : - if first letter is a String : allows everything
 *          - if first letter is a Integer : allows [0-9] and "." and "e" (exponential)
 * Firefox : allows everything
 * Internet Explorer : allows everything
 *
 * Why you should not use input type="number" :
 * When using input type="number" the $parser pipeline of ngModel controller won't be able to access NaN values.
 * For example : viewValue = '1e'  -> $parsers parameter value = "".
 * This is because undefined values are not allowes by default (which can be changed, but better not do it)
 * This makes it impossible to modify the view and model value; to get the view value, pop last character, apply to the view and return to the model.
 *
 * About the ngModel controller pipelines :
 * view value -> $parsers -> model value
 * model value -> $formatters -> view value
 *
 * About the $parsers pipeline :
 * It is an array of functions executed in ascending order.
 * When used with input type="number" :
 * This array has 2 default functions, one of them transforms the datatype of the value from String to Number.
 * To be able to change the value easier (substring), it is better to have access to a String rather than a Number.
 * To access a String, the custom function added to the $parsers pipeline should be unshifted rather than pushed.
 * Unshift gives the closest access to the view.
 *
 * About the $formatters pipeline :
 * It is executed in descending order
 * When used with input type="number"
 * Default function transforms the value datatype from Number to String.
 * To access a String, push to this pipeline. (push brings the function closest to the view value)
 *
 * The flow :
 * When changing ngModel where the directive stands : (In this case only the view has to be changed. $parsers returns the changed model)
 *     -When the value do not has to be modified :
 *     $parsers -> $render();
 *     -When the value has to be modified :
 *     $parsers(view value) --(does view needs to be changed?) -> $render();
 *       |                                  |
 *       |                     $setViewValue(changedViewValue)
 *       |                                  |
 *       --<-------<---------<--------<------
 *
 * When changing ngModel where the directive does not stand :
 *     - When the value does not has to be modified :
 *       -$formatters(model value)-->-- view value
 *     -When the value has to be changed
 *       -$formatters(model vale)-->--(does the value has to be modified) -- (when loop $parsers loop is finished, return modified value)-->view value
 *                                              |
 *                                  $setViewValue(notChangedValue) giving back the non changed value allows the $parsers handle the 'bad' value
 *                                               |                  and avoids it to think the value did not changed
 *                Changed the model <----(the above $parsers loop occurs)
 *

For those having a portable SDK edition on windows, simply add the 2 following path to your system.

F:\ADT_SDK\sdk\platforms
F:\ADT_SDK\sdk\platform-tools

This worked for me.

XMPP is a good solution. I have used it for a push enabled, realtime, Android application. XMPP is powerful, highly extensible and easy to integrate and use.

There are loads of free XMPP servers (though out of courtesy you shouldn't abuse them) and there are open source servers you can run on one of your own boxes. OpenFire is an excellent choice.

The library you want isn't Smack as noted above, it's aSmack. But note, this is a build environment - you will have to build the library.

This is a calculation I did on battery life impact of an XMPP solution:

The Android client must maintain a persistent TCP connection by waking up periodically to send a heartbeat to the XMPP server.
This clearly imposes a cost in terms of power usage. An estimate of this cost is provided below:

• Using a 1400mAh battery (as supplied in the Nexus One and HTC Desire)
• An idle device, connected to an 3G network, uses approximately 5mA
• The wake-up, heartbeat, sleep cycle occurs every 5 minutes, takes three seconds to complete and uses 300mA
• The cost in battery usage per hour is therefore:
  • 36 seconds 300mA = 3mAh sending heartbeat
  • 3600 seconds 5mA = 5mAh at idle
  • 4:95 + 3 = 7:95mAh combined
• A 1400mAh battery lasts approximately 11.6 days at idle and 7.3 days when running the application, which represents an approximate 37% reduction in battery life.
• However, a reduction in battery life of 37% represents the absolute worst case in practice given that devices are rarely completely idle.

If you want to apply to all columns you can use:

df.apply(pd.value_counts)

This will apply a column based aggregation function (in this case value_counts) to each of the columns.

Lets say your company makes 4 different products, your client has another 3 different products from another 3 different companies.

Someday the client thought, why don't we integrate all our systems into one huge system. Ten minutes later their IT department said that will take 2 years.

You (the wise developer) said, why don't we just integrate all the different systems and make them work together in a homogeneous environment? The client manager staring at you... You continued, we will use a Middleware, we will study the Inputs/Outputs of all different systems, the resources they use and then choose an appropriate Middleware framework.

Still explaining to the non tech manager
With Middleware framework in the middle, the first system will produce X stuff, the system Y and Z would consume those outputs and so on.

1NF is the most basic of normal forms - each cell in a table must contain only one piece of information, and there can be no duplicate rows.

2NF and 3NF are all about being dependent on the primary key. Recall that a primary key can be made up of multiple columns. As Chris said in his response:

The data depends on the key [1NF], the whole key [2NF] and nothing but the key [3NF] (so help me Codd).

2NF

Say you have a table containing courses that are taken in a certain semester, and you have the following data:

|-----Primary Key----|               uh oh |
                                           V
CourseID | SemesterID | #Places  | Course Name  |
------------------------------------------------|
IT101    |   2009-1   | 100      | Programming  |
IT101    |   2009-2   | 100      | Programming  |
IT102    |   2009-1   | 200      | Databases    |
IT102    |   2010-1   | 150      | Databases    |
IT103    |   2009-2   | 120      | Web Design   |

This is not in 2NF, because the fourth column does not rely upon the entire key - but only a part of it. The course name is dependent on the Course's ID, but has nothing to do with which semester it's taken in. Thus, as you can see, we have duplicate information - several rows telling us that IT101 is programming, and IT102 is Databases. So we fix that by moving the course name into another table, where CourseID is the ENTIRE key.

Primary Key |

CourseID    |  Course Name |
---------------------------|
IT101       | Programming  |
IT102       | Databases    |
IT103       | Web Design   |

No redundancy!

3NF

Okay, so let's say we also add the name of the teacher of the course, and some details about them, into the RDBMS:

|-----Primary Key----|                           uh oh |
                                                       V
Course  |  Semester  |  #Places   |  TeacherID  | TeacherName  |
---------------------------------------------------------------|
IT101   |   2009-1   |  100       |  332        |  Mr Jones    |
IT101   |   2009-2   |  100       |  332        |  Mr Jones    |
IT102   |   2009-1   |  200       |  495        |  Mr Bentley  |
IT102   |   2010-1   |  150       |  332        |  Mr Jones    |
IT103   |   2009-2   |  120       |  242        |  Mrs Smith   |

Now hopefully it should be obvious that TeacherName is dependent on TeacherID - so this is not in 3NF. To fix this, we do much the same as we did in 2NF - take the TeacherName field out of this table, and put it in its own, which has TeacherID as the key.

 Primary Key |

 TeacherID   | TeacherName  |
 ---------------------------|
 332         |  Mr Jones    |
 495         |  Mr Bentley  |
 242         |  Mrs Smith   |

No redundancy!!

One important thing to remember is that if something is not in 1NF, it is not in 2NF or 3NF either. So each additional Normal Form requires everything that the lower normal forms had, plus some extra conditions, which must all be fulfilled.

SYSDATE returns the system date, of the system on which the database resides

CURRENT_TIMESTAMP returns the current date and time in the session time zone, in a value of datatype TIMESTAMP WITH TIME ZONE

execute this comman

    ALTER SESSION SET TIME_ZONE = '+3:0';

and it will provide you the same result.

I was trying to use the React-Native Expo app with create-react-native-app but for some reason it would launch my simulator and just hang without loading the app. The above answer by ipinak above reset the Xcode CLI tools because attempting to update to most recent Xcode CLI was not working. the two commands are:

rm -rf /Library/Developer/CommandLineTools
xcode-select --install

This process take time because of the download. I am leaving this here for any other would be searches for this specific React-Native Expo fix.

This is because in line

graph(x**3+2*x-4, range(-10, 11))

x is not defined.

The easiest way is to pass the function you want to plot as a string and use eval to evaluate it as an expression.

So your code with minimal modifications will be

import numpy as np  
import matplotlib.pyplot as plt  
def graph(formula, x_range):  
    x = np.array(x_range)  
    y = eval(formula)
    plt.plot(x, y)  
    plt.show()

and you can call it as

graph('x**3+2*x-4', range(-10, 11))

var userPasswordString = new Buffer(baseAuth, 'base64').toString('ascii');

Change this line from your code to this -

var userPasswordString = Buffer.from(baseAuth, 'base64').toString('ascii');

or in my case, I gave the encoding in reverse order

var userPasswordString = Buffer.from(baseAuth, 'utf-8').toString('base64');

ALL YOU HAVE TO DO:

HTML:

<table id="my-table"><tr>
<td> CELL 1 With a lot of text in it</td>
<td> CELL 2 </td>
<td> CELL 3 </td>
<td> CELL 4 With a lot of text in it </td>
<td> CELL 5 </td>
</tr></table>

CSS:

#my-table{width:100%;} /*or whatever width you want*/
#my-table td{width:2000px;} /*something big*/

if you have th you need to set it too like this:

#my-table th{width:2000px;}

body {
  position: fixed;
  height: 100%;
}

Joel's answer is good for reasons you might have to use C, though there are a few others:

• You must meet industry guidelines, which are easier to prove and test for in C
• You have tools to work with C, but not C++ (think not just about the compiler, but all the support tools, coverage, analysis, etc)
• Your target developers are C gurus
• You're writing drivers, kernels, or other low-level code
• You know the C++ compiler isn't good at optimizing the kind of code you need to write
• Your app not only doesn't lend itself to be object-oriented but would be harder to write in that form

In some cases, though, you might want to use C rather than C++:

• You want the performance of assembler without the trouble of coding in assembler (C++ is, in theory, capable of 'perfect' performance, but the compilers aren't as good at seeing optimizations a good C programmer will see)

• The software you're writing is trivial, or nearly so - whip out the tiny C compiler, write a few lines of code, compile and you're all set - no need to open a huge editor with helpers, no need to write practically empty and useless classes, deal with namespaces, etc. You can do nearly the same thing with a C++ compiler and simply use the C subset, but the C++ compiler is slower, even for tiny programs.

• You need extreme performance or small code size and know the C++ compiler will actually make it harder to accomplish due to the size and performance of the libraries.

You contend that you could just use the C subset and compile with a C++ compiler, but you'll find that if you do that you'll get slightly different results depending on the compiler.

Regardless, if you're doing that, you're using C. Is your question really "Why don't C programmers use C++ compilers?" If it is, then you either don't understand the language differences, or you don't understand the compiler theory.

Those classes are common extension points for Java UI designs. First off, realize that they don't necessarily have much to do with each other directly, so trying to find a relationship between them might be counterproductive.

JApplet - A base class that let's you write code that will run within the context of a browser, like for an interactive web page. This is cool and all but it brings limitations which is the price for it playing nice in the real world. Normally JApplet is used when you want to have your own UI in a web page. I've always wondered why people don't take advantage of applets to store state for a session so no database or cookies are needed.

JComponent - A base class for objects which intend to interact with Swing.

JFrame - Used to represent the stuff a window should have. This includes borders (resizeable y/n?), titlebar (App name or other message), controls (minimize/maximize allowed?), and event handlers for various system events like 'window close' (permit app to exit yet?).

JPanel - Generic class used to gather other elements together. This is more important with working with the visual layout or one of the provided layout managers e.g. gridbaglayout, etc. For example, you have a textbox that is bigger then the area you have reserved. Put the textbox in a scrolling pane and put that pane into a JPanel. Then when you place the JPanel, it will be more manageable in terms of layout.

Use the FrameWork version 4.5 and above for your project then problem solved.Because this namespace is under 4.5 and above.

You can use Integer.parseInt() or Integer.valueOf() to get the integer from the string, and catch the exception if it is not a parsable int. You want to be sure to catch the NumberFormatException it can throw.

It may be helpful to note that valueOf() will return an Integer object, not the primitive int.

Swift 5.0

func makeTransform(horizontalDegree: CGFloat, verticalDegree: CGFloat, maxVertical: CGFloat,rotateDegree: CGFloat, maxHorizontal: CGFloat) -> CATransform3D {
    var transform = CATransform3DIdentity
           
    transform.m34 = 1 / -500
    
    let xAnchor = (horizontalDegree / (2 * maxHorizontal)) + 0.5
    let yAnchor = (verticalDegree / (-2 * maxVertical)) + 0.5
    let anchor = CGPoint(x: xAnchor, y: yAnchor)
    
    setAnchorPoint(anchorPoint: anchor, forView: self.imgView)
    let hDegree  = (CGFloat(horizontalDegree) * .pi)  / 180
    let vDegree  = (CGFloat(verticalDegree) * .pi)  / 180
    let rDegree  = (CGFloat(rotateDegree) * .pi)  / 180
    transform = CATransform3DRotate(transform, vDegree , 1, 0, 0)
    transform = CATransform3DRotate(transform, hDegree , 0, 1, 0)
    transform = CATransform3DRotate(transform, rDegree , 0, 0, 1)
    
    return transform
}

func setAnchorPoint(anchorPoint: CGPoint, forView view: UIView) {
    var newPoint = CGPoint(x: view.bounds.size.width * anchorPoint.x, y: view.bounds.size.height * anchorPoint.y)
    var oldPoint = CGPoint(x: view.bounds.size.width * view.layer.anchorPoint.x, y: view.bounds.size.height * view.layer.anchorPoint.y)
    
    newPoint = newPoint.applying(view.transform)
    oldPoint = oldPoint.applying(view.transform)
    
    var position = view.layer.position
    position.x -= oldPoint.x
    position.x += newPoint.x
    
    position.y -= oldPoint.y
    position.y += newPoint.y
    
    print("Anchor: \(anchorPoint)")
    
    view.layer.position = position
    view.layer.anchorPoint = anchorPoint
}

you only need to call the function with your degree. for example:

var transform = makeTransform(horizontalDegree: 20.0 , verticalDegree: 25.0, maxVertical: 25, rotateDegree: 20, maxHorizontal: 25)
imgView.layer.transform = transform

Example:

select Table_name as [Table] , column_name as [Column] , Table_catalog as [Database], table_schema as [Schema]  from information_schema.columns
where table_schema = 'dbo'
order by Table_name,COLUMN_NAME

Just my code

Seed() can be used for later use ---

Example:
>>> import numpy as np
>>> np.random.seed(12)
>>> np.random.rand(4)
array([0.15416284, 0.7400497 , 0.26331502, 0.53373939])
>>>
>>>
>>> np.random.seed(10)
>>> np.random.rand(4)
array([0.77132064, 0.02075195, 0.63364823, 0.74880388])
>>>
>>>
>>> np.random.seed(12) # When you use same seed as before you will get same random output as before
>>> np.random.rand(4)
array([0.15416284, 0.7400497 , 0.26331502, 0.53373939])
>>>
>>>
>>> np.random.seed(10)
>>> np.random.rand(4)
array([0.77132064, 0.02075195, 0.63364823, 0.74880388])
>>>

I do not agree with the rules given in the original post. Here are my rules:

1) You use structs for performance when stored in arrays. (see also When are structs the answer?)

2) You need them in code passing structured data to/from C/C++

3) Do not use structs unless you need them:

• They behave different from "normal objects" (reference types) under assignment and when passing as arguments, which can lead to unexpected behavior; this is particularly dangerous if the person looking at the code does not know they are dealing with a struct.
• They cannot be inherited.
• Passing structs as arguments is more expensive than classes.

Go to Eclipse, Click on Window from Menu bar then "Open Perspective -> other -> SVN Repository Exploring -> Click OK"

Now, after performing "Click OK" you need to go to truck (or place where your project is saved in SVN) then select project(which you want to Delete) then right click -> Delete.

This Will Delete project from subversion.

I guess this has been solved by now but still the best thing to do here is to send the token with your form

{!! csrf_field() !!}

and then in your ajax

$("#try").click(function(){
var url = $(this).attr("data-link");
$.ajax({
    url: "test",
    type:"POST",
    data: { '_token': token, 'someOtherData': someOtherData },
    success:function(data){
        alert(data);
    },error:function(){ 
        alert("error!!!!");
    }
}); //end of ajax
});

The interpretation of the backspace and carriage return characters is left to the software you use for display. A terminal emulator, when displaying \b would move the cursor one step back, and when displaying \r to the beginning of the line. If you print these characters somewhere else, like a text file, the software may choose. to do something else.

When using merged columns, I got it centered by using PHPExcel_Style_Alignment::HORIZONTAL_CENTER_CONTINUOUS instead of PHPExcel_Style_Alignment::HORIZONTAL_CENTER

you are doing several things wrong. The explanation follows the corrected code:

<label id="LblTextCount"></label>
<textarea name="text" onKeyPress="checkLength(this, 512, 'LblTextCount')">
</textarea>

Note the quotes around the id.

function checkLength(object, maxlength, label) {
    charsleft = (maxlength - object.value.length);

    // never allow to exceed the specified limit
    if( charsleft < 0 ) {
        object.value = object.value.substring(0, maxlength-1);
    }

    // set the value of charsleft into the label
    document.getElementById(label).innerHTML = charsleft;
}

First, on your key press event you need to send the label id as a string for it to read correctly. Second, InnerHTML has a lowercase i. Lastly, because you sent the function the string id you can get the element by that id.

Let me know how that works out for you

EDIT Not that by not declaring charsleft as a var, you are implicitly creating a global variable. a better way would be to do the following when declaring it in the function:

var charsleft = ....

I'm able to do one of the following to successfully use a selector - without annotating anything with @objc:

NSNotificationCenter.defaultCenter().addObserver(self,
    selector:"batteryLevelChanged:" as Selector,
    name:"UIDeviceBatteryLevelDidChangeNotification",
    object:nil)    

OR

let notificationSelector: Selector = "batteryLevelChanged:"

NSNotificationCenter.defaultCenter().addObserver(self,
    selector: notificationSelector,
    name:"UIDeviceBatteryLevelDidChangeNotification",
    object:nil)    

My xcrun version shows Swift 1.2, and this works on Xcode 6.4 and Xcode 7 beta 2 (which I thought would be using Swift 2.0):

$xcrun swift --version

Apple Swift version 1.2 (swiftlang-602.0.53.1 clang-602.0.53)

For those who are using Xamarin and don't have access to the GeoCoordinate class, you can use the Android Location class instead:

public static double GetDistanceBetweenCoordinates (double lat1, double lng1, double lat2, double lng2) {
            var coords1 = new Location ("");
            coords1.Latitude = lat1;
            coords1.Longitude = lng1;
            var coords2 = new Location ("");
            coords2.Latitude = lat2;
            coords2.Longitude = lng2;
            return coords1.DistanceTo (coords2);
        }

You are sending a post type with data implemented for a get. your form must be the following:

$.ajax({
url: url,
method: "POST",
data: {data1:"data1",data2:"data2"},
...

Sorry EMS, but I actually just got another response from the matplotlib mailling list (Thanks goes out to Benjamin Root).

The code I am looking for is adjusting the savefig call to:

fig.savefig('samplefigure', bbox_extra_artists=(lgd,), bbox_inches='tight')
#Note that the bbox_extra_artists must be an iterable

This is apparently similar to calling tight_layout, but instead you allow savefig to consider extra artists in the calculation. This did in fact resize the figure box as desired.

import matplotlib.pyplot as plt
import numpy as np

plt.gcf().clear()
x = np.arange(-2*np.pi, 2*np.pi, 0.1)
fig = plt.figure(1)
ax = fig.add_subplot(111)
ax.plot(x, np.sin(x), label='Sine')
ax.plot(x, np.cos(x), label='Cosine')
ax.plot(x, np.arctan(x), label='Inverse tan')
handles, labels = ax.get_legend_handles_labels()
lgd = ax.legend(handles, labels, loc='upper center', bbox_to_anchor=(0.5,-0.1))
text = ax.text(-0.2,1.05, "Aribitrary text", transform=ax.transAxes)
ax.set_title("Trigonometry")
ax.grid('on')
fig.savefig('samplefigure', bbox_extra_artists=(lgd,text), bbox_inches='tight')

This produces:

[edit] The intent of this question was to completely avoid the use of arbitrary coordinate placements of arbitrary text as was the traditional solution to these problems. Despite this, numerous edits recently have insisted on putting these in, often in ways that led to the code raising an error. I have now fixed the issues and tidied the arbitrary text to show how these are also considered within the bbox_extra_artists algorithm.

You can use bcp utility.

To copy the result set from a Transact-SQL statement to a data file, use the queryout option. The following example copies the result of a query into the Contacts.txt data file. The example assumes that you are using Windows Authentication and have a trusted connection to the server instance on which you are running the bcp command. At the Windows command prompt, enter:

bcp "<your query here>" queryout Contacts.txt -c -T

You can use BCP by directly calling as operating sytstem command in SQL Agent job.

Finding Object by reference without, strings, Note make sure the object you pass in is cloned , i use cloneDeep from lodash for that

if object looks like

const obj = {data: ['an Object',{person: {name: {first:'nick', last:'gray'} }]

path looks like

const objectPath = ['data',1,'person',name','last']

then call below method and it will return the sub object by path given

const child = findObjectByPath(obj, objectPath)
alert( child) // alerts "last"


const findObjectByPath = (objectIn: any, path: any[]) => {
    let obj = objectIn
    for (let i = 0; i <= path.length - 1; i++) {
        const item = path[i]
        // keep going up to the next parent
        obj = obj[item] // this is by reference
    }
    return obj
}

How to get the first date of the current month correctly?

LocalDate.now()
         .with( TemporalAdjusters.firstDayOfMonth() )

Or…

YearMonth.now().atDay( 1 )

Or…

LocalDate.now().with ( ChronoField.DAY_OF_MONTH , 1 )

java.time

The java.time framework in Java 8 and later supplants the old java.util.Date/.Calendar classes. The old classes have proven to be troublesome, confusing, and flawed. Avoid them.

The java.time framework is inspired by the highly-successful Joda-Time library, defined by JSR 310, extended by the ThreeTen-Extra project, and explained in the Tutorial.

LocalDate

For a date-only value, without time-of-day, use the LocalDate class. While LocalDate has no assigned time zone, we must specify a time zone in order to determine a date such as “today”. For example, a new day dawns earlier in Paris than in Montréal.

Time zone is crucial in determining today's date. For any given moment, the date varies around the world by zone. Omitting the time zone means the JVM’s current time zone is automatically applied in determining the current date. Any code in the JVM can change the default at runtime, so you are walking on shifting sands. Better to specify your desired/expected time zone explicitly than rely implicitly on the current default.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId zoneId = ZoneId.of ( "America/Montreal" );
LocalDate today = LocalDate.now ( zoneId );
LocalDate firstOfCurrentMonth = today.with ( ChronoField.DAY_OF_MONTH , 1 );

Dump to console.

System.out.println ( "For zoneId: " + zoneId + " today is: " + today + " and first of this month is " + firstOfCurrentMonth );

For zoneId: America/Montreal today is: 2015-11-08 and first of this month is 2015-11-01

Alternatively, use a TemporalAdjuster. For your purpose, you will find handy implementations in the TemporalAdjusters class (note plural s), specifically firstDayOfMonth.

LocalDate firstOfCurrentMonth = today.with( TemporalAdjusters.firstDayOfMonth() ) ;

ZonedDateTime

If you need a time of day, remember that 00:00:00.000 is not always the first moment of the day because of Daylight Saving Time (DST) and perhaps other anomalies. So let java.time determine the correct time of the first moment of the day.

ZonedDateTime zdt = firstOfCurrentMonth.atStartOfDay ( zoneId );

2015-11-01T00:00-04:00[America/Montreal]

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

GET Parent Directory Path and make New directory (name new_dir)

Get Parent Directory Path

os.path.abspath('..')
os.pardir

Example 1

import os
print os.makedirs(os.path.join(os.path.dirname(__file__), os.pardir, 'new_dir'))

Example 2

import os
print os.makedirs(os.path.join(os.path.dirname(__file__), os.path.abspath('..'), 'new_dir'))

The best place to write your JavaScript code is at the end of the document after or right before the </body> tag to load the document first and then execute js code.

<script> ... your code here ... </script>
</body>

And if you write in JQuery the following can be in the head document and it will execute after the document loads:

<script>
$(document).ready(function(){
   //your code here...
});
</script>

Assuming your row number is in B1, you can use INDIRECT:

=INDIRECT("A" & B1)

This takes a cell reference as a string (in this case, the concatenation of A and the value of B1 - 5), and returns the value at that cell.

.register a:link{
    color:#FFFFFF;
}

The SQLite command line utility has a .schema TABLENAME command that shows you the create statements.

Its because the AddDays() method returns a new DateTime, that you are not assigning or using anywhere.

Example of use:

DateTime newDate = endDate.AddDays(2);

To sum it up, #pragma tells the compiler to do stuff. Here are a couple of ways I use it:

• #pragma can be used to ignore compiler warnings. For example, to make GCC shut up about implicit function declarations, you can write:

  #pragma GCC diagnostic ignored "-Wimplicit-function-declaration"
  

  An older version of libportable does this portably.

• #pragma once, when written at the top of a header file, will cause said header file to be included once. libportable checks for pragma once support.

I am not sure but as per my knowledge I share my views. I always accept best answer if I am wrong .

Alarm Manager

The Alarm Manager holds a CPU wake lock as long as the alarm receiver's onReceive() method is executing. This guarantees that the phone will not sleep until you have finished handling the broadcast. Once onReceive() returns, the Alarm Manager releases this wake lock. This means that the phone will in some cases sleep as soon as your onReceive() method completes. If your alarm receiver called Context.startService(), it is possible that the phone will sleep before the requested service is launched. To prevent this, your BroadcastReceiver and Service will need to implement a separate wake lock policy to ensure that the phone continues running until the service becomes available.

Note: The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running. For normal timing operations (ticks, timeouts, etc) it is easier and much more efficient to use Handler.

Timer

timer = new Timer();

    timer.scheduleAtFixedRate(new TimerTask() {

        synchronized public void run() {

            \\ here your todo;
            }

        }, TimeUnit.MINUTES.toMillis(1), TimeUnit.MINUTES.toMillis(1));

Timer has some drawbacks that are solved by ScheduledThreadPoolExecutor. So it's not the best choice

ScheduledThreadPoolExecutor.

You can use java.util.Timer or ScheduledThreadPoolExecutor (preferred) to schedule an action to occur at regular intervals on a background thread.

Here is a sample using the latter:

ScheduledExecutorService scheduler =
    Executors.newSingleThreadScheduledExecutor();

scheduler.scheduleAtFixedRate
      (new Runnable() {
         public void run() {
            // call service
         }
      }, 0, 10, TimeUnit.MINUTES);

So I preferred ScheduledExecutorService

But Also think about that if the updates will occur while your application is running, you can use a Timer, as suggested in other answers, or the newer ScheduledThreadPoolExecutor. If your application will update even when it is not running, you should go with the AlarmManager.

The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running.

Take note that if you plan on updating when your application is turned off, once every ten minutes is quite frequent, and thus possibly a bit too power consuming.

You can use ImportRow method to copy Row from DataTable to DataTable with the same schema:

var row = SourceTable.Rows[RowNum];
DestinationTable.ImportRow(row);

Update:

With your new Edit, I believe:

var desRow = dataTable.NewRow();
var sourceRow = dataTable.Rows[rowNum];
desRow.ItemArray = sourceRow.ItemArray.Clone() as object[];

will work

It is as simple as that ... C++ is providing you a function in STL (Standard Template Library) called sort which runs 20% to 50% faster than the hand-coded quick-sort.

Here is the sample code for it's usage:

std::sort(arr, arr + size);

Use the btoa() function to encode:

console.log(btoa("password")); // cGFzc3dvcmQ=

To decode, you can use the atob() function:

console.log(atob("cGFzc3dvcmQ=")); // password

just an example that uses collection.breakOut

scala> val a : List[Int] = (for( x <- 1 to 10 ) yield x * 3)(collection.breakOut)
a: List[Int] = List(3, 6, 9, 12, 15, 18, 21, 24, 27, 30)

scala> val b : List[Int] = (1 to 10).map(_ * 3)(collection.breakOut)
b: List[Int] = List(3, 6, 9, 12, 15, 18, 21, 24, 27, 30)

Since the POSIX/BusyBox question is closed without providing the right answer (IMHO), I'll post an answer here.

The shortest possible answer is:

[ ${_string_##*$_substring_*} ] || echo Substring found!

or

[ "${_string_##*$_substring_*}" ] || echo 'Substring found!'

Note that the double hash is obligatory with some shells (ash). Above will evaluate [ stringvalue ] when the substring is not found. It returns no error. When the substring is found the result is empty and it evaluates [ ]. This will throw error code 1 since the string is completely substituted (due to *).

The shortest more common syntax:

[ -z "${_string_##*$_substring_*}" ] && echo 'Substring found!'

or

[ -n "${_string_##*$_substring_*}" ] || echo 'Substring found!'

Another one:

[ "${_string_##$_substring_}" != "$_string_" ] && echo 'Substring found!'

or

[ "${_string_##$_substring_}" = "$_string_" ] || echo 'Substring found!'

Note the single equal sign!

Internet E-mail address format (RFC 822)

(,)comma separated sequence of addresses

javax.mail - 1.4.7 parse( String[] ) is not allowed. So we have to give comma separated sequence of addresses into InternetAddress objects. Addresses must follow RFC822 syntax.

String toAddress = "[email protected],[email protected]";
InternetAddress.parse( toAddress );

(;) semi-colon separated sequence of addresses « If group of address list is provided with delimeter as ";" then convert to String array using split method to use the following function.

String[] addressList = { "[email protected]", "[email protected]" };

String toGroup = "[email protected];[email protected]";
String[] addressList2 = toGroup.split(";");

setRecipients(message, addressList);

public static void setRecipients(Message message, Object addresslist) throws AddressException, MessagingException {
    if ( addresslist instanceof String ) { // CharSequence
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse( (String) addresslist  ));
    } else if ( addresslist instanceof String[] ) { // String[] « Array with collection of Strings/
        String[] toAddressList = (String[]) addresslist;
        InternetAddress[] mailAddress_TO = new InternetAddress[ toAddressList.length ];
        for (int i = 0; i < toAddressList.length; i++) {
            mailAddress_TO[i] = new InternetAddress( toAddressList[i] );
        }
        message.setRecipients(Message.RecipientType.TO, mailAddress_TO);
    }
}

Full Example:

public static Properties getMailProperties( boolean addExteraProps ) {
    Properties props = new Properties();
    props.put("mail.transport.protocol", MAIL_TRNSPORT_PROTOCOL);
    props.put("mail.smtp.host", MAIL_SERVER_NAME);
    props.put("mail.smtp.port", MAIL_PORT);

    // Sending Email to the GMail SMTP server requires authentication and SSL.
    props.put("mail.smtp.auth", true);
    if( ENCRYPTION_METHOD.equals("STARTTLS") ) {
        props.put("mail.smtp.starttls.enable", true);
        props.put("mail.smtp.socketFactory.port", SMTP_STARTTLS_PORT); // 587
    } else {
        props.put("mail.smtps.ssl.enable", true);
        props.put("mail.smtp.socketFactory.port", SMTP_SSL_PORT); // 465
    }
    props.put("mail.smtp.socketFactory", SOCKETFACTORY_CLASS);
    return props;
}

public static boolean sendMail(String subject, String contentType, String msg, Object recipients) throws Exception {

    Properties props = getMailProperties( false );
    Session mailSession = Session.getInstance(props, null);
    mailSession.setDebug(true);

    Message message = new MimeMessage( mailSession );
    message.setFrom( new InternetAddress( USER_NAME ) );

    setRecipients(message, recipients);

    message.setSubject( subject );

    String htmlData = "<h1>This is actual message embedded in HTML tags</h1>";
    message.setContent( htmlData, "text/html");

    Transport transport = mailSession.getTransport( MAIL_TRNSPORT_PROTOCOL );
    transport.connect(MAIL_SERVER_NAME, Integer.valueOf(MAIL_PORT), USER_NAME, PASSWORD);
    message.saveChanges(); // don't forget this

    transport.sendMessage(message, message.getAllRecipients());
    transport.close();
}

Using Appache SimpleEmail - commons-email-1.3.1

Example: email.addTo( addressList );

public static void sendSimpleMail() throws Exception {
    Email email = new SimpleEmail();
    email.setSmtpPort(587);

    DefaultAuthenticator defaultAuthenticator = new DefaultAuthenticator( USER_NAME, PASSWORD );

    email.setAuthenticator( defaultAuthenticator );
    email.setDebug(false);
    email.setHostName( MAIL_SERVER_NAME );
    email.setFrom( USER_NAME );
    email.setSubject("Hi");
    email.setMsg("This is a test mail ... :-)");

    //email.addTo( "[email protected]", "Yash" );
    String[] toAddressList = { "[email protected]", "[email protected]" }
    email.addTo( addressList );

    email.setTLS(true);
    email.setStartTLSEnabled( true );
    email.send();
    System.out.println("Mail sent!");
}

Try __weak if you get any warning regarding retain cycle else use __block

Person *strongPerson = [Person new];
__weak Person *weakPerson = person;

Now you can refer weakPerson object inside block.

If you go to the Flat file connection manager under Advanced and Look at the "OutputColumnWidth" description's ToolTip It will tell you that Composit characters may use more spaces. So the "é" in "Société" most likely occupies more than one character.

EDIT: Here's something about it: http://en.wikipedia.org/wiki/Precomposed_character

When is lexing enough, when do you need EBNF?

EBNF really doesn't add much to the power of grammars. It's just a convenience / shortcut notation / "syntactic sugar" over the standard Chomsky's Normal Form (CNF) grammar rules. For example, the EBNF alternative:

S --> A | B

you can achieve in CNF by just listing each alternative production separately:

S --> A      // `S` can be `A`,
S --> B      // or it can be `B`.

The optional element from EBNF:

S --> X?

you can achieve in CNF by using a nullable production, that is, the one which can be replaced by an empty string (denoted by just empty production here; others use epsilon or lambda or crossed circle):

S --> B       // `S` can be `B`,
B --> X       // and `B` can be just `X`,
B -->         // or it can be empty.

A production in a form like the last one B above is called "erasure", because it can erase whatever it stands for in other productions (product an empty string instead of something else).

Zero-or-more repetiton from EBNF:

S --> A*

you can obtan by using recursive production, that is, one which embeds itself somewhere in it. It can be done in two ways. First one is left recursion (which usually should be avoided, because Top-Down Recursive Descent parsers cannot parse it):

S --> S A    // `S` is just itself ended with `A` (which can be done many times),
S -->        // or it can begin with empty-string, which stops the recursion.

Knowing that it generates just an empty string (ultimately) followed by zero or more As, the same string (but not the same language!) can be expressed using right-recursion:

S --> A S    // `S` can be `A` followed by itself (which can be done many times),
S -->        // or it can be just empty-string end, which stops the recursion.

And when it comes to + for one-or-more repetition from EBNF:

S --> A+

it can be done by factoring out one A and using * as before:

S --> A A*

which you can express in CNF as such (I use right recursion here; try to figure out the other one yourself as an exercise):

S --> A S   // `S` can be one `A` followed by `S` (which stands for more `A`s),
S --> A     // or it could be just one single `A`.

Knowing that, you can now probably recognize a grammar for a regular expression (that is, regular grammar) as one which can be expressed in a single EBNF production consisting only from terminal symbols. More generally, you can recognize regular grammars when you see productions similar to these:

A -->        // Empty (nullable) production (AKA erasure).
B --> x      // Single terminal symbol.
C --> y D    // Simple state change from `C` to `D` when seeing input `y`.
E --> F z    // Simple state change from `E` to `F` when seeing input `z`.
G --> G u    // Left recursion.
H --> v H    // Right recursion.

That is, using only empty strings, terminal symbols, simple non-terminals for substitutions and state changes, and using recursion only to achieve repetition (iteration, which is just linear recursion - the one which doesn't branch tree-like). Nothing more advanced above these, then you're sure it's a regular syntax and you can go with just lexer for that.

But when your syntax uses recursion in a non-trivial way, to produce tree-like, self-similar, nested structures, like the following one:

S --> a S b    // `S` can be itself "parenthesized" by `a` and `b` on both sides.
S -->          // or it could be (ultimately) empty, which ends recursion.

then you can easily see that this cannot be done with regular expression, because you cannot resolve it into one single EBNF production in any way; you'll end up with substituting for S indefinitely, which will always add another as and bs on both sides. Lexers (more specifically: Finite State Automata used by lexers) cannot count to arbitrary number (they are finite, remember?), so they don't know how many as were there to match them evenly with so many bs. Grammars like this are called context-free grammars (at the very least), and they require a parser.

Context-free grammars are well-known to parse, so they are widely used for describing programming languages' syntax. But there's more. Sometimes a more general grammar is needed -- when you have more things to count at the same time, independently. For example, when you want to describe a language where one can use round parentheses and square braces interleaved, but they have to be paired up correctly with each other (braces with braces, round with round). This kind of grammar is called context-sensitive. You can recognize it by that it has more than one symbol on the left (before the arrow). For example:

A R B --> A S B

You can think of these additional symbols on the left as a "context" for applying the rule. There could be some preconditions, postconditions etc. For example, the above rule will substitute R into S, but only when it's in between A and B, leaving those A and B themselves unchanged. This kind of syntax is really hard to parse, because it needs a full-blown Turing machine. It's a whole another story, so I'll end here.

Simply use this query, I have tried it as per my scenario and it works well

ALTER TABLE katalog ADD FOREIGN KEY (`Sprache`) REFERENCES Sprache(`ID`);

You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.

So if you want to use your code, you could do:

df = DataFrame(eval(data))

But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:

data = []
for row in result_set:
    data.append({'value': row["tag_expression"], 'key': row["tag_name"]})

But probably even this is not needed, as depending on what is exactly in your result_set you could probably:

• provide this directly to a DataFrame: DataFrame(result_set)
• or use the pandas read_sql_query function to do this for you (see docs on this)

This was an issue for me because I already had the SDK installed under a different directory. In order to tell Android Studio to where the SDK is you need to get to the settings, but the "SDK tools directory is missing" dialog always exits the whole program when you click "Finish". Here's how I "solved" it:

1. Delete your ~/.Android* folders (losing all of your settings :/).
2. Run Android Studio. It will show you a welcome wizard where it tries to download the SDK again (and fails due to my rubbish internet).
3. Click the X on the wizard window. That will enable you to get to the normal welcome dialog.
4. Go to Settings->Project Defaults->Project Structure and change the Android SDK location to the correct one.

Deleting the .Android Studio folders may be unnecessary - I never tried pressing the X on the original error dialog - I only tried "Finish" which exits Android Studio. It is possible if you click the X you can get to settings but unfortunately I can't go back and check now.

trick that is working here is the id that I have assigned to ImageView "imgView.setId(v)" and after that applying onClickListener to that I am again fetching the id of the view....I have also commented inside the code so that its easy to understand, I hope this may be very useful... Happy Coding... :)

    //best way to deal with this is sqlbulkcopy 
    //but if you dont like it you can do it like this
    //read current sql table in an adapter
    //add rows of datatable , I have mentioned a simple way of it
    //and finally updating changes

    Dim cnn As New SqlConnection("connection string")        
    cnn.Open()
    Dim cmd As New SqlCommand("select * from  sql_server_table", cnn)
    Dim da As New SqlDataAdapter(cmd)       
    Dim ds As New DataSet()
    da.Fill(ds, "sql_server_table")
    Dim cb As New SqlCommandBuilder(da)        

    //for each datatable row
    ds.Tables("sql_server_table").Rows.Add(COl1, COl2)

    da.Update(ds, "sql_server_table")

Create a reverse dictionary using the calendar module (which, like any module, you will need to import):

{month: index for index, month in enumerate(calendar.month_abbr) if month}

In Python versions before 2.7, due to dict comprehension syntax not being supported in the language, you would have to do

dict((month, index) for index, month in enumerate(calendar.month_abbr) if month)

Based on this solution from bluefeet here is a stored procedure that uses dynamic sql to generate the transposed table. It requires that all the fields are numeric except for the transposed column (the column that will be the header in the resulting table):

You can test it with the table provided with this command:

exec SQLTranspose 'yourTable', 'color'

You just need to overwrite what you're deleting with the next value in the array, propagate that change, and then keep in mind where the new end is:

int array[] = {1, 2, 3, 4, 5, 6, 7, 8, 9};

// delete 3 (index 2)
for (int i = 2; i < 8; ++i)
    array[i] = array[i + 1]; // copy next element left

Now your array is {1, 2, 4, 5, 6, 7, 8, 9, 9}. You cannot delete the extra 9 since this is a statically-sized array, you just have to ignore it. This can be done with std::copy:

std::copy(array + 3, // copy everything starting here
          array + 9, // and ending here, not including it,
          array + 2) // to this destination

In C++11, use can use std::move (the algorithm overload, not the utility overload) instead.

More generally, use std::remove to remove elements matching a value:

// remove *all* 3's, return new ending (remaining elements unspecified)
auto arrayEnd = std::remove(std::begin(array), std::end(array), 3);

Even more generally, there is std::remove_if.

Note that the use of std::vector<int> may be more appropriate here, as its a "true" dynamically-allocated resizing array. (In the sense that asking for its size() reflects removed elements.)

String.split() can also accept a regular expression:

input.split(/[ ,]+/);

This particular regex splits on a sequence of one or more commas or spaces, so that e.g. multiple consecutive spaces or a comma+space sequence do not produce empty elements in the results.

For any special characters you should use '\'. So, for matching parentheses - /\(/

An old question with lots of answers, so another one won't be an issue. Some general functions to get the start and end of all sorts of time units.

For startOf and endOf week, the start day of the week defaults to Sunday (0) but any day can be passed (Monday - 1, Tuesday - 2, etc.). Only uses Gregorian calendar though.

The functions don't mutate the source date, so to see if a date is in the same week as some other date (week starting on Monday):

if (d >= startOf('week', d1, 1) && d <= endOf('week', d1, 1)) {
  // d is in same week as d1
}

or in the current week starting on Sunday:

if (d >= startOf('week') && d <= endOf('week')) {
  // d is in the current week
}

// Returns a new Date object set to start of given unit_x000D_

Use int(@array) as it threats the argument as scalar.

Individual TLD's can place their own rules & restrictions on domains names as they see fit, such as to accomodate local languages.

For example, according to the CIRA, Canada's .ca domain names are allowed:

• Letters a through z, and the following accented characters: é ë ê è â à æ ô œ ù û ü ç î ï ÿ. Note that Domain Names are not case sensitive. This means there will be no distinction made between upper case letters and lower case letters (A = a);

• The numbers 0123456789, and

• The hyphen character ("-) (although it cannot be used to start or end a Domain Name).

The maximum length is 63 characters, except each accented character reduces that limit by 4 characters.

(Source)

_{Incidentally, this allows for around 4 Quadragintillion domain name possibilities (not counting sub-domains) for dot-ca domains.}

You don't need to go level up and use .. since all buttons are on the same level:

//button[contains(.,'Arcade Reader')]/preceding-sibling::button[@name='settings']

Add this toolbar.getBackground().setAlpha(0); to inside OnCreate method. The add this: android:elevation="0dp" android:background="@android:color/transparent to your toolbar xml file.

I'm new to SQL, but came across this issue in a course I was taking and found that assigning the query to the project specifically helped to eliminate the multi-part error. For example the project I created was CTU SQL Project so I made sure I started my script with USE [CTU SQL Project] as my first line like below.

USE [CTU SQL Project]
SELECT Advisors.First_Name, Advisors.Last_Name...and so on.

json.dumps() returns the JSON string representation of the python dict. See the docs

You can't do r['rating'] because r is a string, not a dict anymore

Perhaps you meant something like

r = {'is_claimed': 'True', 'rating': 3.5}
json = json.dumps(r) # note i gave it a different name
file.write(str(r['rating']))

In case you want to use bootstrap radio to check one of them depends on the result of your checked var in the .ts file.

component.html

<h1>Radio Group #1</h1>
<div class="btn-group btn-group-toggle" data-toggle="buttons" >
   <label [ngClass]="checked ? 'active' : ''" class="btn btn-outline-secondary">
     <input name="radio" id="radio1" value="option1" type="radio"> TRUE
   </label>
   <label [ngClass]="!checked ? 'active' : ''" class="btn btn-outline-secondary">
     <input name="radio" id="radio2" value="option2" type="radio"> FALSE
   </label>
</div>

component.ts file

@Component({
  selector: '',
  templateUrl: './.component.html',
  styleUrls: ['./.component.css']
})
export class radioComponent implements OnInit {
  checked = true;
}

You can use the FindByValue method to search the DropDownList for an Item with a Value matching the parameter.

dropdownlist.ClearSelection();
dropdownlist.Items.FindByValue(value).Selected = true;

Alternatively you can use the FindByText method to search the DropDownList for an Item with Text matching the parameter.

Before using the FindByValue method, don't forget to reset the DropDownList so that no items are selected by using the ClearSelection() method. It clears out the list selection and sets the Selected property of all items to false. Otherwise you will get the following exception.

"Cannot have multiple items selected in a DropDownList"

I'm using the following trick:

I select the declaration of the class with the data-members and press:

Ctrl+C, Shift+Ctrl+C, Ctrl+V.

• The first command copies the declaration to the clipboard,
• The second command is a shortcut that invokes the PROGRAM
• The last command overwrites the selection by text from the clipboard.

The PROGRAM gets the declaration from the clipboard, finds the name of the class, finds all members and their types, generates constructor and copies it all back into the clipboard.

We are doing it with freshmen on my "Programming-I" practice (Charles University, Prague) and most of students gets it done till the end of the hour.

If you want to see the source code, let me know.

A handle is a sort of pointer in that it is typically a way of referencing some entity.

It would be more accurate to say that a pointer is one type of handle, but not all handles are pointers.

For example, a handle may also be some index into an in memory table, which corresponds to an entry that itself contains a pointer to some object.

The key thing is that when you have a "handle", you neither know nor care how that handle actually ends up identifying the thing that it identifies, all you need to know is that it does.

It should also be obvious that there is no single answer to "what exactly is a handle", because handles to different things, even in the same system, may be implemented in different ways "under the hood". But you shouldn't need to be concerned with those differences.

You can use the Chrome DevTools Utilities API copy() command for copying the string representation of the specified object to the clipboard.

If you have lots of objects then you can actually JSON.stringify() all your objects and keep on appending them to a string. Now use copy() method to copy the complete string to clipboard.

Without reading you can't do this. But you can use a work around like below.

You can use mark() and reset() methods to do this.

mark(int readlimit) method marks the current position in this input stream.

reset() method repositions this stream to the position at the time the mark method was last called on this input stream.

Before you can use the mark and reset, you need to test out whether these operations are supported on the inputstream you’re reading off. You can do that with markSupported.

The mark method accepts an limit (integer), which denotes the maximum number of bytes that are to be read ahead. If you read more than this limit, you cannot return to this mark.

To apply this functionalities for this use case, we need to mark the position as 0 and then read the input stream. There after we need to reset the input stream and the input stream will be reverted to the original one.

    if (inputStream.markSupported()) {
          inputStream.mark(0);
          if (inputStream.read() != -1) {
               inputStream.reset();
          } else {
               //Inputstream is empty
          }
    }

Here if the input stream is empty then read() method will return -1.

Looking at most of the replies, they seem overly complicated. Angular has built in mechanisms to unregister.

Use the deregistration function returned by $on :

// Register and get a handle to the listener
var listener = $scope.$on('someMessage', function () {
    $log.log("Message received");
});

// Unregister
$scope.$on('$destroy', function () {
    $log.log("Unregistering listener");
    listener();
});

very old question, i know. but with the new f-strings (starting from python 3.6) there are fresh options. so here for completeness:

from datetime import datetime

dt = datetime.now()

# str.format
strg = '{:%B %d, %Y}'.format(dt)
print(strg)  # July 22, 2017

# datetime.strftime
strg = dt.strftime('%B %d, %Y')
print(strg)  # July 22, 2017

# f-strings in python >= 3.6
strg = f'{dt:%B %d, %Y}'
print(strg)  # July 22, 2017

strftime() and strptime() Behavior explains what the format specifiers mean.

If you just want to store the dict in a single file, use pickle like that

import pickle

a = {'hello': 'world'}

with open('filename.pickle', 'wb') as handle:
    pickle.dump(a, handle)

with open('filename.pickle', 'rb') as handle:
    b = pickle.load(handle)

If you want to save and restore multiple dictionaries in multiple files for caching and store more complex data, use anycache. It does all the other stuff you need around pickle

from anycache import anycache

@anycache(cachedir='path/to/files')
def myfunc(hello):
    return {'hello', hello}

Anycache stores the different myfunc results depending on the arguments to different files in cachedir and reloads them.

See the documentation for any further details.

In Java, by default AES supports a 128 Bit key, if you plans to use 192 Bit or 256 Bit key, java complier will throw Illegal key size Exception, which you are getting.

The solution is as victor & James suggested, you will need to download JCE (Java Cryptography Extension) as per your JRE version,(java6, java7 or java8).

The JCE zip contains following JAR:

1. local_policy.jar
2. US_export_policy.jar

You need to replace these jar form your <JAVA_HOME>/jre/lib/security. if you are on a unix system the will probably refer to /home/urs/usr/lib/jvm/java-<version>-oracle/

Sometimes just replacing local_policy.jar, US_export_policy.jar in security folder doesn't work on unix, so I suggest to copy security folder to your desktop first, replace the jar's @Desktop/security folder, delete the security folder from /jre/lib/ & move the Desktop security folder to /jre/lib/.

eg :: sudo mv security /usr/lib/jvm/java-7-oracle/jre/lib

The concept of creating or dropping a database is not meaningful for an embedded database engine like SQLite. It only has meaning with a client-sever database system, such as used by MySQL or Postgres.

To create a new database, just do sqlite_open() or from the command line sqlite3 databasefilename.

To drop a database, delete the file.

Reference: sqlite - Unsupported SQL

I presume SELECT user FROM dual; should give you the current user

and SELECT sys_context('userenv','instance_name') FROM dual; the name of the instance

I believe you can get SID as SELECT sys_context('USERENV', 'SID') FROM DUAL;

This was alluded to in another comment, but you could try something like this.

Sub FilterAndDelete()

Application.DisplayAlerts = False 

     With Sheet1 'Change this to your sheet name

         .AutoFilterMode = False   
         .Range("A3:K3").AutoFilter
         .Range("A3:K3").AutoFilter Field:=5, Criteria1:="none"
         .UsedRange.Offset(1, 0).Resize(ActiveSheet.UsedRange.Rows.Count - 1).Rows.Delete 

     End With

Application.DisplayAlerts = True

I haven't tested this and it is from memory, so it may require some tweaking but it should get the job done without looping through thousands of rows. You'll need to remove the 11-Jul so that UsedRange is correct or change the offset to 2 rows instead of 1 in the .Offset(1,0).

Generally, before I do .Delete I will run the macro with .Select instead of the Delete that way I can be sure the correct range will be deleted, that may be worth doing to check to ensure the appropriate range is being deleted.

Unfortunately, Xcode doesn't have anything nearly as extensive as VS or Jalopy for Eclipse available. There are SOME disparate features, such as Structure > Re-Indent as well as the auto-formatting used when you paste code into your source file. I am totally with you, though; there definitely should be something in there to help with formatting issues.

The reason is that the data doesn't match the datatype. I have come across the same issues that I forgot to make the fields match. Though my case is not same as yours, but it shows the similar error message.

The situation is that I copy a table, but accidently I misspell one field, so I change it using the ALTER after creating the database. And the order of fields in both table is not identical. so when I use the INSERT INTO TableName SELECT * FROM TableName, the result showed the similar errors: Operand type clash: datetime is incompatible with uniqueidentifier

This is a simiple example:

use example
go
create table Test1 (
    id int primary key,
    item uniqueidentifier,
    inserted_at datetime
    )
go
create table Test2 (
    id int primary key,
    inserted_at datetime
    )
go
alter table Test2 add item uniqueidentifier;
go

--insert into Test1 (id, item, inserted_at) values (1, newid(), getdate()), (2, newid(), getdate());


insert into Test2 select * from Test1;

select * from Test1;
select * from Test2;

The error message is:

Msg 206, Level 16, State 2, Line 24
Operand type clash: uniqueidentifier is incompatible with datetime

    IF CHARINDEX('TextToSearch',@TextWhereISearch, 0) > 0 => TEXT EXISTS

    IF PATINDEX('TextToSearch', @TextWhereISearch) > 0 => TEXT EXISTS

    Additionally we can also use LIKE but I usually don't use LIKE.

In order to check if your variable is something you could go like:

s='Hello World'
if isinstance(s,str):
#do something here,

The output of isistance will give you a boolean True or False value so you can adjust accordingly. You can check the expected acronym of your value by initially using: type(s) This will return you type 'str' so you can use it in the isistance function.

You can delete IDEA configuration directory to reset everything to the defaults. If you want to reset the editor Colors&Fonts, then just switch the scheme to Default.

If the values are related, why not encapsulate them in a class and just use the plain old Dictionary?

A mutable object has to have at least a method able to mutate the object. For example, the list object has the append method, which will actually mutate the object:

>>> a = [1,2,3]
>>> a.append('hello') # `a` has mutated but is still the same object
>>> a
[1, 2, 3, 'hello']

but the class float has no method to mutate a float object. You can do:

>>> b = 5.0 
>>> b = b + 0.1
>>> b
5.1

but the = operand is not a method. It just make a bind between the variable and whatever is to the right of it, nothing else. It never changes or creates objects. It is a declaration of what the variable will point to, since now on.

When you do b = b + 0.1 the = operand binds the variable to a new float, wich is created with te result of 5 + 0.1.

When you assign a variable to an existent object, mutable or not, the = operand binds the variable to that object. And nothing more happens

In either case, the = just make the bind. It doesn't change or create objects.

When you do a = 1.0, the = operand is not wich create the float, but the 1.0 part of the line. Actually when you write 1.0 it is a shorthand for float(1.0) a constructor call returning a float object. (That is the reason why if you type 1.0 and press enter you get the "echo" 1.0 printed below; that is the return value of the constructor function you called)

Now, if b is a float and you assign a = b, both variables are pointing to the same object, but actually the variables can't comunicate betweem themselves, because the object is inmutable, and if you do b += 1, now b point to a new object, and a is still pointing to the oldone and cannot know what b is pointing to.

but if c is, let's say, a list, and you assign a = c, now a and c can "comunicate", because list is mutable, and if you do c.append('msg'), then just checking a you get the message.

(By the way, every object has an unique id number asociated to, wich you can get with id(x). So you can check if an object is the same or not checking if its unique id has changed.)

Stream API

FloatingActionButton extends ImageView. So, it's simple as like introducing an ImageView in your layout. Here is an XML sample.

<android.support.design.widget.FloatingActionButton   xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/somedrawable"
    android:layout_gravity="right|bottom"
    app:borderWidth="0dp"
    app:rippleColor="#ffffff"/>

app:borderWidth="0dp" is added as a workaround for elevation issues.

On Google'e Gson library, for having a JsonObject, or more abstract a JsonElement:

import com.google.gson.JsonElement;
import com.google.gson.JsonParser;

JsonElement json = JsonParser.parseReader( new InputStreamReader(new FileInputStream("/someDir/someFile.json"), "UTF-8") );

This is not demanding a given Object structure for receiving/reading the json string.

You have indented part of your code in settings.py:

# Uncomment the next line to enable the admin:
     'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    #'django.contrib.admindocs',
     'tinymce',
     'sorl.thumbnail',
     'south',
     'django_facebook',
     'djcelery',
     'devserver',
     'main',

Therefore, it is giving you an error.

If you use JDK version from 9+, you should select

Run > Edit Configurations... > Select JUnit template.

Then, select @argfile (Java 9+) as in the image below. Please try it. Good luck friends.

My solution in Header parameters with example is user="test" is:

@RequestMapping(value = "/restURL")
  public String serveRest(@RequestBody String body, @RequestHeader HttpHeaders headers){

System.out.println(headers.get("user"));
}

Converting a JKS KeyStore to a single PEM file can easily be accomplished using the following command:

keytool -list -rfc -keystore "myKeystore.jks" | sed -e "/-*BEGIN [A-Z]*-*/,/-*END [A-Z]-*/!d" >> "myKeystore.pem"

Explanation:

1. keytool -list -rfc -keystore "myKeystore.jks" lists everything in the 'myKeyStore.jks' KeyStore in PEM format. However, it also prints extra information.
2. | sed -e "/-*BEGIN [A-Z]*-*/,/-*END [A-Z]-*/!d" filters out everything we don't need. We are left with only the PEMs of everything in the KeyStore.
3. >> "myKeystore.pem" write the PEMs to the file 'myKeyStore.pem'.

How to break out in java??

Ans: Best way: System.exit(0);

Java language provides three jump statemnts that allow you to interrupt the normal flow of program.

These include break , continue ,return ,labelled break statement for e.g

import java.util.Scanner;
class demo
{   
    public static void main(String args[])
    {
            outerLoop://Label
            for(int i=1;i<=10;i++)
            {
                    for(int j=1;j<=i;j++)
                    {   
                        for(int k=1;k<=j;k++)
                        {
                            System.out.print(k+"\t");
                            break outerLoop;
                        }
                     System.out.println();                  
                    }
             System.out.println();
            }
    }   
}

Output: 1

Now Note below Program:

import java.util.Scanner;
class demo
{   
    public static void main(String args[])
    {
            for(int i=1;i<=10;i++)
            {
                    for(int j=1;j<=i;j++)
                    {   
                        for(int k=1;k<=j;k++)
                        {
                            System.out.print(k+"\t");
                            break ;
                        }                   
                    }
             System.out.println();
            }
    }   
}

output:

1
11
111
1111

and so on upto

1111111111

Similarly you can use continue statement just replace break with continue in above example.

Things to Remember :

A case label cannot contain a runtime expressions involving variable or method calls

outerLoop:
Scanner s1=new Scanner(System.in);
int ans=s1.nextInt();
// Error s1 cannot be resolved

private static String getMessageDigest(String message, String algorithm) {
 MessageDigest digest;
 try {
  digest = MessageDigest.getInstance(algorithm);
  byte data[] = digest.digest(message.getBytes("UTF-8"));
  return convertByteArrayToHexString(data);
 } catch (NoSuchAlgorithmException | UnsupportedEncodingException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
 return null;
}

You can call above method with different algorithms like below.

getMessageDigest(message, "MD5");
getMessageDigest(message, "SHA-256");
getMessageDigest(message, "SHA-1");

You can refer this link for complete application.

You can use this as well:

String uri = "tel:" + posted_by.replaceAll("[^0-9|\\+]", "");

A scrolling comes from a box with class pre-scrollable

<div class="pre-scrollable"></div>

Wish it helps.

You need to put the JavaScript at the end of the body tag.

It doesn't find it because it's not in the DOM yet!

You can also wrap it in the onload event handler like this:

window.onload = function() {
var refButton = document.getElementById( 'btnButton' );
refButton.onclick = function() {
   alert( 'I am clicked!' );
}
}

If you do all of things above and still get stuck, just try reopening your Android Studio.

Your formula is wrong. You probably meant something like:

=IF(AND(NOT(ISBLANK(Q2));NOT(ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Another equivalent:

=IF(NOT(OR(ISBLANK(Q2);ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Or even shorter:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";IF(Q2<=R2;"1";"0"))

OR EVEN SHORTER:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";--(Q2<=R2))

Methods can only declare local variables. That is why the compiler reports an error when you try to declare it as public.

In the case of local variables you can not use any kind of accessor (public, protected or private).

You should also know what the static keyword means. In method checkYourself, you use the Integer array locations.

The static keyword distinct the elements that are accessible with object creation. Therefore they are not part of the object itself.

public class Test { //Capitalized name for classes are used in Java
   private final init[] locations; //key final mean that, is must be assigned before object is constructed and can not be changed later. 

   public Test(int[] locations) {
      this.locations = locations;//To access to class member, when method argument has the same name use `this` key word. 
   }

   public boolean checkYourSelf(int value) { //This method is accessed only from a object.
      for(int location : locations) {
         if(location == value) {
            return true; //When you use key word return insied of loop you exit from it. In this case you exit also from whole method.
         }
      }
      return false; //Method should be simple and perform one task. So you can get more flexibility. 
   }
   public static int[] locations = {1,2,3};//This is static array that is not part of object, but can be used in it. 

   public static void main(String[] args) { //This is declaration of public method that is not part of create object. It can be accessed from every place.
      Test test = new Test(Test.locations); //We declare variable test, and create new instance (object) of class Test.  
      String result;
      if(test.checkYourSelf(2)) {//We moved outside the string
        result = "Hurray";        
      } else {
        result = "Try again"
      }
      System.out.println(result); //We have only one place where write is done. Easy to change in future.
   } 
}

The npm module anyid provides flexible API to generate various kinds of string ID / code.

To generate random string in A-Za-z0-9 using 48 random bytes:

const id = anyid().encode('Aa0').bits(48 * 8).random().id();
// G4NtiI9OYbSgVl3EAkkoxHKyxBAWzcTI7aH13yIUNggIaNqPQoSS7SpcalIqX0qGZ

To generate fixed length alphabet only string filled by random bytes:

const id = anyid().encode('Aa').length(20).random().id();
// qgQBBtDwGMuFHXeoVLpt

Internally it uses crypto.randomBytes() to generate random.

One Additional point:

When you are converting from tsql to plsql you have to worry about no_data_found exception

DECLARE
   v_var NUMBER;
BEGIN
   SELECT clmn INTO v_var FROM tbl;
Exception when no_data_found then v_var := null; --what ever handle the exception.
END;

In tsql if no data found then the variable will be null but no exception

If you have a list and you want to know where within the list an element exists that matches a given criteria, you can use the FindIndex instance method. Such as

int index = list.FindIndex(f => f.Bar == 17);

Where f => f.Bar == 17 is a predicate with the matching criteria.

In your case you might write

int index = pricePublicList.FindIndex(item => item.Size == 200);
if (index >= 0) 
{
    // element exists, do what you need
}

Simplest way - just put in the Eclipse plugins folder. You can start Eclipse with the -clean option to make sure Eclipse cleans its' plugins cache and sees the new plugin.

In general, it is far more recommended to install plugins using proper update sites.

It looks like someone might have revoked the permissions on sys.configurations for the public role. Or denied access to this view to this particular user. Or the user has been created after the public role was removed from the sys.configurations tables.

Provide SELECT permission to public user sys.configurations object.

Although you can gzip using a reverse proxy such as nginx, lighttpd or in varnish. It can be beneficial to have most http optimisations such as gzipping at the application level so that you can have a much granular approach on what asset's to gzip.

I have actually created my own gzip module for expressjs / connect called gzippo https://github.com/tomgco/gzippo although new it does do the job. Plus it uses node-compress instead of spawning the unix gzip command.

You can add the following to your pom.xml:

<build>
<defaultGoal>install</defaultGoal>
<plugins>
  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
      <source>1.6</source>
      <target>1.6</target>
    </configuration>
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.3.1</version>
    <configuration>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
          <mainClass>com.mycompany.package.MainClass</mainClass>
        </manifest>
      </archive>
    </configuration>
  </plugin>
  <plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
      <archive>
        <manifest>
          <mainClass>com.mycompany.package.MainClass</mainClass>
        </manifest>
      </archive>
    </configuration>
    <executions>
      <execution>
        <id>make-my-jar-with-dependencies</id>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
  </plugin>
</plugins>
</build>

Afterwards you have to switch via the console to the directory, where the pom.xml is located. Then you have to execute mvn assembly:single and then your executable JAR file with dependencies will be hopefully build. You can check it when switching to the output (target) directory with cd ./target and starting your jar with a command similiar to java -jar mavenproject1-1.0-SNAPSHOT-jar-with-dependencies.jar.

I tested this with Apache Maven 3.0.3.

Try using this command : (this will stop tomcat servlet this really helps)

sudo service tomcat7 stop

or

sudo tomcat7 restart (if you need a restart)

While the accepted answer will work most of the times, I have encountered (still do not know why) some cases that is does not. A slight modification of the query by using the WITH OVERRIDE in RECONFIGURE gives the solution

Use Master
GO

EXEC master.dbo.sp_configure 'show advanced options', 1
RECONFIGURE WITH OVERRIDE
GO

EXEC master.dbo.sp_configure 'xp_cmdshell', 1
RECONFIGURE WITH OVERRIDE
GO

The expected output is

Configuration option 'show advanced options' changed from 0 to 1. Run the RECONFIGURE statement to install.
Configuration option 'xp_cmdshell' changed from 0 to 1. Run the RECONFIGURE statement to install.

There is a len method:

>>> a = 'a string of some length'
>>> a.__len__()
23
>>> a.__len__
<method-wrapper '__len__' of str object at 0x02005650>

TAXI ANALOGY

Intent

Intents are typically used for starting Services. For example:

Intent intent = new Intent(CurrentClass.this, ServiceClass.class);
startService(intent);

This is like when you call for a taxi:

Myself = CurrentClass
Taxi Driver = ServiceClass

Pending Intent

You will need to use something like this:

Intent intent = new Intent(CurrentClass.this, ServiceClass.class);
PendingIntent pi = PendingIntent.getService(parameter, parameter, intent, parameter);
getDataFromThirdParty(parameter, parameter, pi, parameter);

Now this Third party will start the service acting on your behalf. A real life analogy is Uber or Lyft who are both taxi companies.

You send a request for a ride to Uber/Lyft. They will then go ahead and call one of their drivers on your behalf.

Therefore:

Uber/Lyft ------ ThirdParty which receives PendingIntent
Myself --------- Class calling PendingIntent
Taxi Driver ---- ServiceClass

This index size limit seems to be larger on 64 bit builds of MySQL.

I was hitting this limitation trying to dump our dev database and load it on a local VMWare virt. Finally I realized that the remote dev server was 64 bit and I had created a 32 bit virt. I just created a 64 bit virt and I was able to load the database locally.

Call the pd.DataFrame constructor directly:

df = pd.DataFrame(table, columns=headers)
df

   Heading1  Heading2
0         1         2
1         3         4

This is a method that uses a FileUpload control in asp.net:

byte[] buffer = new byte[fu.FileContent.Length];
Stream s = fu.FileContent;
s.Read(buffer, 0, buffer.Length);
//Then save 'buffer' to the varbinary column in your db where you want to store the image.

Here is what I would recommend.

It should conform to C89, and be completely portable. In particular, it works also on pipes and sockets on POSIXy systems.

The idea is that we read the input in large-ish chunks (READALL_CHUNK), dynamically reallocating the buffer as we need it. We only use realloc(), fread(), ferror(), and free():

#include <stdlib.h>
#include <stdio.h>
#include <errno.h>

/* Size of each input chunk to be
   read and allocate for. */
#ifndef  READALL_CHUNK
#define  READALL_CHUNK  262144
#endif

#define  READALL_OK          0  /* Success */
#define  READALL_INVALID    -1  /* Invalid parameters */
#define  READALL_ERROR      -2  /* Stream error */
#define  READALL_TOOMUCH    -3  /* Too much input */
#define  READALL_NOMEM      -4  /* Out of memory */

/* This function returns one of the READALL_ constants above.
   If the return value is zero == READALL_OK, then:
     (*dataptr) points to a dynamically allocated buffer, with
     (*sizeptr) chars read from the file.
     The buffer is allocated for one extra char, which is NUL,
     and automatically appended after the data.
   Initial values of (*dataptr) and (*sizeptr) are ignored.
*/
int readall(FILE *in, char **dataptr, size_t *sizeptr)
{
    char  *data = NULL, *temp;
    size_t size = 0;
    size_t used = 0;
    size_t n;

    /* None of the parameters can be NULL. */
    if (in == NULL || dataptr == NULL || sizeptr == NULL)
        return READALL_INVALID;

    /* A read error already occurred? */
    if (ferror(in))
        return READALL_ERROR;

    while (1) {

        if (used + READALL_CHUNK + 1 > size) {
            size = used + READALL_CHUNK + 1;

            /* Overflow check. Some ANSI C compilers
               may optimize this away, though. */
            if (size <= used) {
                free(data);
                return READALL_TOOMUCH;
            }

            temp = realloc(data, size);
            if (temp == NULL) {
                free(data);
                return READALL_NOMEM;
            }
            data = temp;
        }

        n = fread(data + used, 1, READALL_CHUNK, in);
        if (n == 0)
            break;

        used += n;
    }

    if (ferror(in)) {
        free(data);
        return READALL_ERROR;
    }

    temp = realloc(data, used + 1);
    if (temp == NULL) {
        free(data);
        return READALL_NOMEM;
    }
    data = temp;
    data[used] = '\0';

    *dataptr = data;
    *sizeptr = used;

    return READALL_OK;
}

Above, I've used a constant chunk size, READALL_CHUNK == 262144 (256*1024). This means that in the worst case, up to 262145 chars are wasted (allocated but not used), but only temporarily. At the end, the function reallocates the buffer to the optimal size. Also, this means that we do four reallocations per megabyte of data read.

The 262144-byte default in the code above is a conservative value; it works well for even old minilaptops and Raspberry Pis and most embedded devices with at least a few megabytes of RAM available for the process. Yet, it is not so small that it slows down the operation (due to many read calls, and many buffer reallocations) on most systems.

For desktop machines at this time (2017), I recommend a much larger READALL_CHUNK, perhaps #define READALL_CHUNK 2097152 (2 MiB).

Because the definition of READALL_CHUNK is guarded (i.e., it is defined only if it is at that point in the code still undefined), you can override the default value at compile time, by using (in most C compilers) -DREADALL_CHUNK=2097152 command-line option -- but do check your compiler options for defining a preprocessor macro using command-line options.
