In may case it was just a typo which corrupts and prevents parsing of JSON settings file

Try to apply the following settings shown below:

1) Give the necessary permission to the IIS_IUSRS user on IIS Server (Right click on the web site then Edit Permissions > Security).

2) If you use .NET Framework 4, be sure that .NET Framework version is v4.0 on the Application Pool that your web site uses.

3) Open Commanp Prompt as administrator and run iisreset command in order to restart IIS Server.

Hope this helps...

It looks like the answer is at least 12 million if you have a beefy server, your server software is optimized for it, you have enough clients. If you test from one client to one server, the number of port numbers on the client will be one of the obvious resource limits (Each TCP connection is defined by the unique combination of IP and port number at the source and destination).

(You need to run multiple clients as otherwise you hit the 64K limit on port numbers first)

When it comes down to it, this is a classic example of the witticism that "the difference between theory and practise is much larger in practise than in theory" - in practise achieving the higher numbers seems to be a cycle of a. propose specific configuration/architecture/code changes, b. test it till you hit a limit, c. Have I finished? If not then d. work out what was the limiting factor, e. go back to step a (rinse and repeat).

Here is an example with 2 million TCP connections onto a beefy box (128GB RAM and 40 cores) running Phoenix http://www.phoenixframework.org/blog/the-road-to-2-million-websocket-connections - they ended up needing 50 or so reasonably significant servers just to provide the client load (their initial smaller clients maxed out to early, eg "maxed our 4core/15gb box @ 450k clients").

Here is another reference for go this time at 10 million: http://goroutines.com/10m.

This appears to be java based and 12 million connections: https://mrotaru.wordpress.com/2013/06/20/12-million-concurrent-connections-with-migratorydata-websocket-server/

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

UPDATE - I do not have Total DNS enabled at GoDaddy because the domain is hosted at DiscountASP. As such, I could not add an A Record and that is why GoDaddy was only offering to forward my subdomain to a different site. I finally realized that I had to go to DiscountASP to add the A Record to point to DreamHost. Now waiting to see if it all works!

Of course, use the stinkin' IP! I'm not sure why that wasn't registering for me. I guess their helper text example of pointing to another url was throwing me off.

Thanks for both of the replies. I 'got it' as soon as I read Bryant's response which was first but Saif kicked it up a notch and added a little more detail.

Thanks!

Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "] with array("title" => "Welcome ")

Using pgadmin4 :

1. Select roles in side menu
2. Select properties in dashboard.
3. Click Edit and select privileges

Now there you can enable or disable login, roles and other options

1) If the object is created via a pointer and that pointer is later deleted or given a new address to point to, does the object that it was pointing to call its destructor (assuming nothing else is pointing to it)?

It depends on the type of pointers. For example, smart pointers often delete their objects when they are deleted. Ordinary pointers do not. The same is true when a pointer is made to point to a different object. Some smart pointers will destroy the old object, or will destroy it if it has no more references. Ordinary pointers have no such smarts. They just hold an address and allow you to perform operations on the objects they point to by specifically doing so.

2) Following up on question 1, what defines when an object goes out of scope (not regarding to when an object leaves a given {block}). So, in other words, when is a destructor called on an object in a linked list?

That's up to the implementation of the linked list. Typical collections destroy all their contained objects when they are destroyed.

So, a linked list of pointers would typically destroy the pointers but not the objects they point to. (Which may be correct. They may be references by other pointers.) A linked list specifically designed to contain pointers, however, might delete the objects on its own destruction.

A linked list of smart pointers could automatically delete the objects when the pointers are deleted, or do so if they had no more references. It's all up to you to pick the pieces that do what you want.

3) Would you ever want to call a destructor manually?

Sure. One example would be if you want to replace an object with another object of the same type but don't want to free memory just to allocate it again. You can destroy the old object in place and construct a new one in place. (However, generally this is a bad idea.)

// pointer is destroyed because it goes out of scope,
// but not the object it pointed to. memory leak
if (1) {
 Foo *myfoo = new Foo("foo");
}


// pointer is destroyed because it goes out of scope,
// object it points to is deleted. no memory leak
if(1) {
 Foo *myfoo = new Foo("foo");
 delete myfoo;
}

// no memory leak, object goes out of scope
if(1) {
 Foo myfoo("foo");
}

If you want to nuke all tables anyway, you can dispense with niceties such as CASCADE by putting all tables into a single statement. This also makes execution quicker.

SELECT 'TRUNCATE TABLE ' || string_agg('"' || tablename || '"', ', ') || ';' 
FROM pg_tables WHERE schemaname = 'public';

Executing it directly:

DO $$
DECLARE tablenames text;
BEGIN    
    tablenames := string_agg('"' || tablename || '"', ', ') 
        FROM pg_tables WHERE schemaname = 'public';
    EXECUTE 'TRUNCATE TABLE ' || tablenames;
END; $$

Replace TRUNCATE with DROP as applicable.

If you change your time column into row names, then you can use as.data.frame(as.table(mat)) for simple cases like this.

Example:

data <- c(0.1, 0.2, 0.3, 0.3, 0.4, 0.5)
dimnames <- list(time=c(0, 0.5, 1), name=c("C_0", "C_1"))
mat <- matrix(data, ncol=2, nrow=3, dimnames=dimnames)
as.data.frame(as.table(mat))
  time name Freq
1    0  C_0  0.1
2  0.5  C_0  0.2
3    1  C_0  0.3
4    0  C_1  0.3
5  0.5  C_1  0.4
6    1  C_1  0.5

In this case time and name are both factors. You may want to convert time back to numeric, or it may not matter.

CAUTION:

The begin <code> end while <condition> is rejected by Ruby's author Matz. Instead he suggests using Kernel#loop, e.g.

loop do 
  # some code here
  break if <condition>
end 

Here's an email exchange in 23 Nov 2005 where Matz states:

|> Don't use it please.  I'm regretting this feature, and I'd like to
|> remove it in the future if it's possible.
|
|I'm surprised.  What do you regret about it?

Because it's hard for users to tell

  begin <code> end while <cond>

works differently from

  <code> while <cond>

RosettaCode wiki has a similar story:

During November 2005, Yukihiro Matsumoto, the creator of Ruby, regretted this loop feature and suggested using Kernel#loop.

I fixed such a problem by putting a div down the nav link

 <div [ngClass]="{'nav-div': tab['active']}"></div>

and giving this css to it.

.nav-div {
    width: inherit;
    position: relative;
    height: 8px;
    background: white;
    top: 4px
  }

and nav link css as

 .nav-link {
    position: relative;
    top: 8px;

    &.active {
      box-shadow: rgba(0, 0, 0, 0.3) 0 1px 4px -1px;
    }
  }

Hope this helps!

As the thread mentioned in the comment, get-command in powershell can also work it out. For example, you can type get-command npm and the output is as below:

Another way of doing this would be using Aggregation. You should be able to achieve a similar result using a single query. Such as this:

Item.objects.values("contest").annotate(Count("id"))

I did not test this specific query, but this should output a count of the items for each value in contests as a dictionary.

I use Apache server, so I've used mod_proxy module. Enable modules:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Then add:

ProxyPass /your-proxy-url/ http://service-url:serviceport/

Finally, pass proxy-url to your script.

In .Net 4.5+ use WebUtility

Just for formatting I'm submitting this as an answer.

Couldn't find any good examples comparing them so:

string testString = "http://test# space 123/text?var=val&another=two";
Console.WriteLine("UrlEncode:         " + System.Web.HttpUtility.UrlEncode(testString));
Console.WriteLine("EscapeUriString:   " + Uri.EscapeUriString(testString));
Console.WriteLine("EscapeDataString:  " + Uri.EscapeDataString(testString));
Console.WriteLine("EscapeDataReplace: " + Uri.EscapeDataString(testString).Replace("%20", "+"));

Console.WriteLine("HtmlEncode:        " + System.Web.HttpUtility.HtmlEncode(testString));
Console.WriteLine("UrlPathEncode:     " + System.Web.HttpUtility.UrlPathEncode(testString));

//.Net 4.0+
Console.WriteLine("WebUtility.HtmlEncode: " + WebUtility.HtmlEncode(testString));
//.Net 4.5+
Console.WriteLine("WebUtility.UrlEncode:  " + WebUtility.UrlEncode(testString));

Outputs:

UrlEncode:             http%3a%2f%2ftest%23+space+123%2ftext%3fvar%3dval%26another%3dtwo
EscapeUriString:       http://test#%20space%20123/text?var=val&another=two
EscapeDataString:      http%3A%2F%2Ftest%23%20space%20123%2Ftext%3Fvar%3Dval%26another%3Dtwo
EscapeDataReplace:     http%3A%2F%2Ftest%23+space+123%2Ftext%3Fvar%3Dval%26another%3Dtwo

HtmlEncode:            http://test# space 123/text?var=val&another=two
UrlPathEncode:         http://test#%20space%20123/text?var=val&another=two

//.Net 4.0+
WebUtility.HtmlEncode: http://test# space 123/text?var=val&another=two
//.Net 4.5+
WebUtility.UrlEncode:  http%3A%2F%2Ftest%23+space+123%2Ftext%3Fvar%3Dval%26another%3Dtwo

In .Net 4.5+ use WebUtility.UrlEncode

This appears to replicate HttpUtility.UrlEncode (pre-v4.0) for the more common characters:
Uri.EscapeDataString(testString).Replace("%20", "+").Replace("'", "%27").Replace("~", "%7E")
Note: EscapeUriString will keep a valid uri string, which causes it to use as many plaintext characters as possible.

See this answer for a Table Comparing the various Encodings:
https://stackoverflow.com/a/11236038/555798

Line Breaks All of them listed here (other than HttpUtility.HtmlEncode) will convert "\n\r" into %0a%0d or %0A%0D

Please feel free to edit this and add new characters to my test string, or leave them in the comments and I'll edit it.

CMake is actually pretty good for this. The key part was everyone on the Windows side has to remember to run CMake before loading in the solution, and everyone on our Mac side would have to remember to run it before make.

The hardest part was as a Windows developer making sure your structural changes were in the cmakelist.txt file and not in the solution or project files as those changes would probably get lost and even if not lost would not get transferred over to the Mac side who also needed them, and the Mac guys would need to remember not to modify the make file for the same reasons.

It just requires a little thought and patience, but there will be mistakes at first. But if you are using continuous integration on both sides then these will get shook out early, and people will eventually get in the habit.

The quick one-liner, inline way

 await new Promise(resolve => setTimeout(resolve, 1000));

You need to execute this as a dynamic sp like

DECLARE @ExcludedList VARCHAR(MAX)

SET @ExcludedList = '3,4,22,6014'
declare @sql nvarchar(Max)

Set @sql='SELECT * FROM [A] WHERE Id NOT IN ('+@ExcludedList+')'

exec sp_executesql @sql

To achieve what you want and have a better organisation through your files, you can create a index.js to export your helper files.

Let's say you have a folder called /helpers. Inside this folder you can create your functions divided by content, actions, or anything you like.

Example:

/* Utils.js */
/* This file contains functions you can use anywhere in your application */

function formatName(label) {
   // your logic
}

function formatDate(date) {
   // your logic
}

// Now you have to export each function you want
export {
   formatName,
   formatDate,
};

Let's create another file which has functions to help you with tables:

/* Table.js */
/* Table file contains functions to help you when working with tables */

function getColumnsFromData(data) {
   // your logic
}

function formatCell(data) {
   // your logic
}

// Export each function
export {
   getColumnsFromData,
   formatCell,
};

Now the trick is to have a index.js inside the helpers folder:

/* Index.js */
/* Inside this file you will import your other helper files */

// Import each file using the * notation
// This will import automatically every function exported by these files
import * as Utils from './Utils.js';
import * as Table from './Table.js';

// Export again
export {
   Utils,
   Table,
};

Now you can import then separately to use each function:

import { Table, Utils } from 'helpers';

const columns = Table.getColumnsFromData(data);
Table.formatCell(cell);

const myName = Utils.formatName(someNameVariable);

Hope it can help to organise your files in a better way.

Yes, the list type is a good approximation. You can use names() on your list to set and retrieve the 'keys':

> foo <- vector(mode="list", length=3)
> names(foo) <- c("tic", "tac", "toe")
> foo[[1]] <- 12; foo[[2]] <- 22; foo[[3]] <- 33
> foo
$tic
[1] 12

$tac
[1] 22

$toe
[1] 33

> names(foo)
[1] "tic" "tac" "toe"
> 

To expand on Peter's answer - you could make Search a first-class resource:

POST    /searches          # create a new search
GET     /searches          # list all searches (admin)
GET     /searches/{id}     # show the results of a previously-run search
DELETE  /searches/{id}     # delete a search (admin)

The Search resource would have fields for color, make model, garaged status, etc and could be specified in XML, JSON, or any other format. Like the Car and Garage resource, you could restrict access to Searches based on authentication. Users who frequently run the same Searches can store them in their profiles so that they don't need to be re-created. The URLs will be short enough that in many cases they can be easily traded via email. These stored Searches can be the basis of custom RSS feeds, and so on.

There are many possibilities for using Searches when you think of them as resources.

The idea is explained in more detail in this Railscast.

Full version:

<? echo date('F Y'); ?>

Short version:

<? echo date('M Y'); ?>

Here is a good reference for the different date options.

update

To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp parameter for the date() function. Like this:

echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));

This will also work (it's typically used to get the last day of the previous month):

echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));

Hope that helps.

if anyone needs this for NGINX configuration file here is the snippet:

}

Just for completeness, you can get a list of kernels with jupyter kernelspec list, but I ran into a case where one of the kernels did not show up in this list. You can find all kernel names by opening a Jupyter notebook and selecting Kernel -> Change kernel. If you do not see everything in this list when you run jupyter kernelspec list, try looking in common Jupyter folders:

ls ~/.local/share/jupyter/kernels  # usually where local kernels go
ls /usr/local/share/jupyter/kernels  # usually where system-wide kernels go
ls /usr/share/jupyter/kernels  # also where system-wide kernels can go

Also, you can delete a kernel with jupyter kernelspec remove or jupyter kernelspec uninstall. The latter is an alias for remove. From the in-line help text for the command:

uninstall
    Alias for remove
remove
    Remove one or more Jupyter kernelspecs by name.

There is two ways: regular expressions and string (str) methods.

String methods are usually faster ( ~2x ).

import re, timeit
p = re.compile('.*(.mp3|.avi)$', re.IGNORECASE)
file_name = 'test.mp3'
print(bool(t.match(file_name))
%timeit bool(t.match(file_name)

792 ns ± 1.83 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

file_name = 'test.mp3'
extensions = ('.mp3','.avi')
print(file_name.lower().endswith(extensions))
%timeit file_name.lower().endswith(extensions)

274 ns ± 4.22 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

In the endpoint tag you need to include the property address=""

<endpoint address="" binding="webHttpBinding" bindingConfiguration="SecureBasicRest" behaviorConfiguration="svcEndpoint" name="webHttp" contract="SvcContract.Authenticate" />

From here and d5e5's comment:

You'll have to switch the output to csv-mode and switch to file output.

sqlite> .mode csv
sqlite> .output test.csv
sqlite> select * from tbl1;
sqlite> .output stdout

Well, a string is an IEnumerable and also implements an indexer, so you can iterate through it or reference each character in the string by index.

The fastest way to get what you want is probably the ToCharArray() method of a String:

var myString = "12345";

var charArray = myString.ToCharArray(); //{'1','2','3','4','5'}

You can then convert each Char to a string, or parse them into bytes or integers. Here's a Linq-y way to do that:

byte[] byteArray = myString.ToCharArray().Select(c=>byte.Parse(c.ToString())).ToArray();

A little more performant if you're using ASCII/Unicode strings:

byte[] byteArray = myString.ToCharArray().Select(c=>(byte)c - 30).ToArray();

That code will only work if you're SURE that each element is a number; otherisw the parsing will throw an exception. A simple Regex that will verify this is true is "^\d+$" (matches a full string consisting of one or more digit characters), used in the Regex.IsMatch() static method.

:sav newfile | !rm #

Note that it does not remove the old file from the buffer list. If that's important to you, you can use the following instead:

:sav newfile | bd# | !rm #

Java is strongly typed. 0 and 1 are numbers, which is a different type than a boolean. A number will never be equal to a boolean.

You're missing an ending anchor.

if(Regex.IsMatch(myString, "^[A-Za-z]{2}[0-9]{2}\z")) {
    // ...
}

Here's a demo.

EDIT: If you can have anything between an initial 2 letters and a final 2 numbers:

if(Regex.IsMatch(myString, @"^[A-Za-z]{2}.*\d{2}\z")) {
    // ...
}

Here's a demo.

I would like to offer the way I do this:

<form action="/route" method="POST">
<input type="hidden" name="_method" value="DELETE"> 
<input type="hidden" name="_token" value="the_token">
<button type="submit" class="btn btn-link" onclick="if (!confirm('Are you sure?')) { return false }"><span>Delete</span></button>
</form>

Component 2, the directive component can define a input property (@input annotation in Typescript). And Component 1 can pass that property to the directive component from template.

See this SO answer How to do inter communication between a master and detail component in Angular2?

and how input is being passed to child components. In your case it is directive.

Here a first attempt at the top of my head.

$configFiles = Get-ChildItem . *.config -rec
foreach ($file in $configFiles)
{
    (Get-Content $file.PSPath) |
    Foreach-Object { $_ -replace "Dev", "Demo" } |
    Set-Content $file.PSPath
}

You could use the add-on module for Jackson which handles Hibernate lazy-loading.

More info on https://github.com/FasterXML/jackson-datatype-hibernate wich support hibernate 3 and 4 separately.

To expand on runeh's answer:

>>> def foo(a):
...    x = 2
...    return x + a

>>> import inspect

>>> inspect.getsource(foo)
u'def foo(a):\n    x = 2\n    return x + a\n'

print inspect.getsource(foo)
def foo(a):
   x = 2
   return x + a

EDIT: As pointed out by @0sh this example works using ipython but not plain python. It should be fine in both, however, when importing code from source files.

("0" + this.getDate()).slice(-2)

for the date, and similar:

("0" + (this.getMonth() + 1)).slice(-2)

There are many articles about writing code to import an excel file, but this is a manual/shortcut version:

If you don't need to import your Excel file programmatically using code you can do it very quickly using the menu in SQL Management Studio.

The quickest way to get your Excel file into SQL is by using the import wizard:

1. Open SSMS (Sql Server Management Studio) and connect to the database where you want to import your file into.
2. Import Data: in SSMS in Object Explorer under 'Databases' right-click the destination database, select Tasks, Import Data. An import wizard will pop up (you can usually just click 'Next' on the first screen).

3. The next window is 'Choose a Data Source', select Excel:

   • In the 'Data Source' dropdown list select Microsoft Excel (this option should appear automatically if you have excel installed).

   • Click the 'Browse' button to select the path to the Excel file you want to import.

   • Select the version of the excel file (97-2003 is usually fine for files with a .XLS extension, or use 2007 for newer files with a .XLSX extension)
   • Tick the 'First Row has headers' checkbox if your excel file contains headers.
   • Click next.

4. On the 'Choose a Destination' screen, select destination database:
   • Select the 'Server name', Authentication (typically your sql username & password) and select a Database as destination. Click Next.

5. On the 'Specify Table Copy or Query' window:

   • For simplicity just select 'Copy data from one or more tables or views', click Next.

6. 'Select Source Tables:' choose the worksheet(s) from your Excel file and specify a destination table for each worksheet. If you don't have a table yet the wizard will very kindly create a new table that matches all the columns from your spreadsheet. Click Next.

7. Click Finish.

If you are thinking of running a server and trying to decide how many connections can be served from one machine, you may want to read about the C10k problem and the potential problems involved in serving lots of clients simultaneously.

df$Gene <- as.factor(df$Gene)
do.call(rbind, lapply(split(df,df$Gene), function(x) {return(x[which.max(x$Value),])}))

Just using base R

You can do the following:

echo '<div class="my_class">';
echo ($cart->count_product > 0) ? $cart->count_product : '';
echo '</div>';

If you want to have it inside your statement, do this:

if($cart->count_product > 0) 
{
    echo '<div class="my_class">'.$cart->count_product.'</div>';
}

You don't need the else statement, since you're only going to output the above when it's truthy anyway.

Use DecimalFormat

  double answer = 5.0;
   DecimalFormat df = new DecimalFormat("###.#");
  System.out.println(df.format(answer));

Another option - to convert to C++ besides Shed Skin - is Pythran.

To quote High Performance Python by Micha Gorelick and Ian Ozsvald:

Pythran is a Python-to-C++ compiler for a subset of Python that includes partial numpy support. It acts a little like Numba and Cython—you annotate a function’s arguments, and then it takes over with further type annotation and code specialization. It takes advantage of vectorization possibilities and of OpenMP-based parallelization possibilities. It runs using Python 2.7 only.

One very interesting feature of Pythran is that it will attempt to automatically spot parallelization opportunities (e.g., if you’re using a map), and turn this into parallel code without requiring extra effort from you. You can also specify parallel sections using pragma omp > directives; in this respect, it feels very similar to Cython’s OpenMP support.

Behind the scenes, Pythran will take both normal Python and numpy code and attempt to aggressively compile them into very fast C++—even faster than the results of Cython.

You should note that this project is young, and you may encounter bugs; you should also note that the development team are very friendly and tend to fix bugs in a matter of hours.

Use apply().

It writes the changes to the RAM immediately and waits and writes it to the internal storage(the actual preference file) after. Commit writes the changes synchronously and directly to the file.

span { display: table-cell; height: (your-height + px); vertical-align: middle; }

For spans to work like a table-cell (or any other element, for that matter), height must be specified. I've given spans a height, and they work just fine--but you must add height to get them to do what you want.

Try creating a handler for select event on those elements and in the handler you can clear the selection.

Take a look at this:

Clear Text Selection with JavaScript

It's an example of clearing the selection. You'd only need to modify it to work only on the specific element that you need.

There may be other potential solutions out there (I am still looking) but thus far in my search for the same functionality, I have only found http://www.maxivista.com/ . As far as I can tell through, it only supports a dual monitor, not multiple.

I tried both the 32-bit and 64-bit installers of both Oracle and IBM Java on Windows, and the presence of C:\Windows\SysWOW64\java.exe seems to be a reliable way to determine that 32-bit Java is available. I haven't tested older versions of these installers, but this at least looks like it should be a reliable way to test, for the most recent versions of Java.

 <td rowspan="2" style="text-align:left;vertical-align:top;padding:0">Save a lot</td>

That should do it.

I've face this problem so I create my projetc in a different path, then move to the location where the other projects are, after looking to gradle files, I've notice that my newer project have this:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

The classpath of my newest project's gradle is 1.5.0, and the other projects ar 1.2.3, Than I've made the changes and so far so good, everthing is working fine until now.

This is how its working for me. The redirection used will redirect all the normal http as well.

const bodyParser = require('body-parser');
const path = require('path');
const http = require('http');
const app = express();
var request = require('request');
//For https

var fs = require('fs');
var options = {
  key: fs.readFileSync('certificates/private.key'),
  cert: fs.readFileSync('certificates/certificate.crt'),
  ca: fs.readFileSync('certificates/ca_bundle.crt')
};

// API file for interacting with MongoDB
const api = require('./server/routes/api');

// Parsers
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

// Angular DIST output folder
app.use(express.static(path.join(__dirname, 'dist')));

// API location
app.use('/api', api);

// Send all other requests to the Angular app
app.get('*', (req, res) => {
  res.sendFile(path.join(__dirname, 'dist/index.html'));
});
app.use(function(req,resp,next){
  if (req.headers['x-forwarded-proto'] == 'http') {
      return resp.redirect(301, 'https://' + req.headers.host + '/');
  } else {
      return next();
  }
});

jQuery: How to capture the TAB keypress within a Textbox

How to handle <tab> in textarea?

This is the default code given to save a video captured by camera

import numpy as np
import cv2

cap = cv2.VideoCapture(0)

# Define the codec and create VideoWriter object
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('output.avi',fourcc, 20.0, (640,480))

while(cap.isOpened()):
    ret, frame = cap.read()
    if ret==True:
        frame = cv2.flip(frame,0)

        # write the flipped frame
        out.write(frame)

        cv2.imshow('frame',frame)
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
    else:
        break

# Release everything if job is finished
cap.release()
out.release()
cv2.destroyAllWindows()

For about two minutes of a clip captured that FULL HD

Using

cap = cv2.VideoCapture(0,cv2.CAP_DSHOW)
cap.set(3,1920)
cap.set(4,1080)
out = cv2.VideoWriter('output.avi',fourcc, 20.0, (1920,1080))

The file saved was more than 150MB

Then had to use ffmpeg to reduce the size of the file saved, between 30MB to 60MB based on the quality of the video that is required changed using crf lower the crf better the quality of the video and larger the file size generated. You can also change the format avi,mp4,mkv,etc

Then i found ffmpeg-python

Here a code to save numpy array of each frame as video using ffmpeg-python

import numpy as np
import cv2
import ffmpeg

def save_video(cap,saving_file_name,fps=33.0):

    while cap.isOpened():
        ret, frame = cap.read()
        if ret:
            i_width,i_height = frame.shape[1],frame.shape[0]
            break

    process = (
    ffmpeg
        .input('pipe:',format='rawvideo', pix_fmt='rgb24',s='{}x{}'.format(i_width,i_height))
        .output(saved_video_file_name,pix_fmt='yuv420p',vcodec='libx264',r=fps,crf=37)
        .overwrite_output()
        .run_async(pipe_stdin=True)
    )

    return process

if __name__=='__main__':

    cap = cv2.VideoCapture(0,cv2.CAP_DSHOW)
    cap.set(3,1920)
    cap.set(4,1080)
    saved_video_file_name = 'output.avi'
    process = save_video(cap,saved_video_file_name)

    while(cap.isOpened()):
        ret, frame = cap.read()
        if ret==True:
            frame = cv2.flip(frame,0)
            process.stdin.write(
                cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
                    .astype(np.uint8)
                    .tobytes()
                    )

            cv2.imshow('frame',frame)
            if cv2.waitKey(1) & 0xFF == ord('q'):
                process.stdin.close()
                process.wait()
                cap.release()
                cv2.destroyAllWindows()
                break
        else:
            process.stdin.close()
            process.wait()

            cv2.destroyAllWindows()
            break

ObservableCollection Caveat

Mentioned above (Said Roohullah Allem)

What makes the ObservableCollection class unique is that this class supports an event named CollectionChanged.

Keep this in mind...If you adding a large number of items to an ObservableCollection the UI will also update that many times. This can really gum up or freeze your UI. A work around would be to create a new list, add all the items then set your property to the new list. This hits the UI once. Again...this is for adding a large number of items.

When i analyzed your code. I have also faced the same problem but my problem is if i give value for both first and last name means it is working fine. but when i give only one value means it says 400. anyway use the .andDo(print()) method to find out the error

public void testGetUserByName() throws Exception {
    String firstName = "Jack";
    String lastName = "s";       
    this.userClientObject = client.createClient();
    mockMvc.perform(get("/byName")
            .sessionAttr("userClientObject", this.userClientObject)
            .param("firstName", firstName)
            .param("lastName", lastName)               
    ).andDo(print())
     .andExpect(status().isOk())
            .andExpect(content().contentType("application/json"))
            .andExpect(jsonPath("$[0].id").exists())
            .andExpect(jsonPath("$[0].fn").value("Marge"));
}

If your problem is org.springframework.web.bind.missingservletrequestparameterexception you have to change your code to

@RequestMapping(value = "/byName", method = RequestMethod.GET)
    @ResponseStatus(HttpStatus.OK)
    public
    @ResponseBody
    String getUserByName(
        @RequestParam( value="firstName",required = false) String firstName,
        @RequestParam(value="lastName",required = false) String lastName, 
        @ModelAttribute("userClientObject") UserClient userClient)
    {

        return client.getUserByName(userClient, firstName, lastName);
    }

Here is my solution, without overdoing it.

    private static string AppendAtPosition(string baseString, int position, string character)
    {
        var sb = new StringBuilder(baseString);
        for (int i = position; i < sb.Length; i += (position + character.Length))
            sb.Insert(i, character);
        return sb.ToString();
    }


    Console.WriteLine(AppendAtPosition("abcdefghijklmnopqrstuvwxyz", 5, "-"));

This is best solution : https://developer.android.com/studio/write/tool-attributes

This is design attributes we can set activty context in xml like

tools:context=".activity.ActivityName"

Adapter:

tools:context="com.PackegaName.AdapterName"

You can navigate to java class when clicking on the marked icon and tools have more features like

tools:text=""
tools:visibility:""
tools:listItems=""//for recycler view 

etx

$url = 'http://legis.senado.leg.br/dadosabertos/materia/tramitando';
$xml = file_get_contents("xml->{$url}");
$xml = simplexml_load_file($url);

Suppose you have:

var j = {0: "1", 1: "2", 2: "3", 3: "4"};

You could get the values with (supported in practically all browser versions):

Object.keys(j).map(function(_) { return j[_]; })

or simply:

Object.values(j)

Output:

["1", "2", "3", "4"]

I'm able to execute your exact query by just making sure there is a semicolon at the end of my select statement. (Output is actual, connection params removed.)

echo "select 1 from dual;" | sqlplus -s username/password@host:1521/service 

Output:

         1
----------
         1

Note that is should matter but this is running on Mac OS X Snow Leopard and Oracle 11g.

I think it would make more sense to use "Find" function in Excel instead of For Each loop. It works much much faster and it's designed for such actions. Try this:

 Sub FindSomeCells(strSearchQuery As String)   

    Set SearchRange = Worksheets("Sheet1").Range("A1:A100")
    FindWhat = strSearchQuery
    Set FoundCells = FindAll(SearchRange:=SearchRange, _
                            FindWhat:=FindWhat, _
                            LookIn:=xlValues, _
                            LookAt:=xlWhole, _
                            SearchOrder:=xlByColumns, _
                            MatchCase:=False, _
                            BeginsWith:=vbNullString, _
                            EndsWith:=vbNullString, _
                            BeginEndCompare:=vbTextCompare)
    If FoundCells Is Nothing Then
        Debug.Print "Value Not Found"
    Else
        For Each FoundCell In FoundCells
            FoundCell.Interior.Color = XlRgbColor.rgbLightGreen
        Next FoundCell
    End If

End Sub

That subroutine searches for some string and returns a collections of cells fullfilling your search criteria. Then you can do whatever you want with the cells in that collection. Forgot to add the FindAll function definition:

Function FindAll(SearchRange As Range, _
                FindWhat As Variant, _
               Optional LookIn As XlFindLookIn = xlValues, _
                Optional LookAt As XlLookAt = xlWhole, _
                Optional SearchOrder As XlSearchOrder = xlByRows, _
                Optional MatchCase As Boolean = False, _
                Optional BeginsWith As String = vbNullString, _
                Optional EndsWith As String = vbNullString, _
                Optional BeginEndCompare As VbCompareMethod = vbTextCompare) As Range
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' FindAll
' This searches the range specified by SearchRange and returns a Range object
' that contains all the cells in which FindWhat was found. The search parameters to
' this function have the same meaning and effect as they do with the
' Range.Find method. If the value was not found, the function return Nothing. If
' BeginsWith is not an empty string, only those cells that begin with BeginWith
' are included in the result. If EndsWith is not an empty string, only those cells
' that end with EndsWith are included in the result. Note that if a cell contains
' a single word that matches either BeginsWith or EndsWith, it is included in the
' result.  If BeginsWith or EndsWith is not an empty string, the LookAt parameter
' is automatically changed to xlPart. The tests for BeginsWith and EndsWith may be
' case-sensitive by setting BeginEndCompare to vbBinaryCompare. For case-insensitive
' comparisons, set BeginEndCompare to vbTextCompare. If this parameter is omitted,
' it defaults to vbTextCompare. The comparisons for BeginsWith and EndsWith are
' in an OR relationship. That is, if both BeginsWith and EndsWith are provided,
' a match if found if the text begins with BeginsWith OR the text ends with EndsWith.

How to bring back “Browser mode” in IE11?

Easy way to bring back is just go to Emulation (ctrl +8)

and do change user agent string. (see attached image)

char ch = Character.MIN_VALUE;

The code above will initialize the variable ch with the minimum value that a char can have (i.e. \u0000).

Another thing that people may find useful when using the develop method is the --user option to install without sudo. Ex:

python setup.py develop --user

instead of

sudo python setup.py develop

upstream in the github example is just the name they've chosen to refer to that repository. You may choose any that you like when using git remote add. Depending on what you select for this name, your git pull usage will change. For example, if you use:

git remote add upstream git://github.com/somename/original-project.git

then you would use this to pull changes:

git pull upstream master

But, if you choose origin for the name of the remote repo, your commands would be:

To name the remote repo in your local config: git remote add origin git://github.com/somename/original-project.git

And to pull: git pull origin master

A simple solution is to install jshon library :

jshon -l < /tmp/test.json

You can also use a spline. Feed in the values you have and interpolate points between your known points. Linking this with a least-squares fit, moving average or kalman filter (as mentioned in other answers) gives you the ability to calculate the points inbetween your "known" points.

Being able to interpolate the values between your knowns gives you a nice smooth transition and a /reasonable/ approximation of what data would be present if you had a higher-fidelity. http://en.wikipedia.org/wiki/Spline_interpolation

Different splines have different characteristics. The one's I've seen most commonly used are Akima and Cubic splines.

Another algorithm to consider is the Ramer-Douglas-Peucker line simplification algorithm, it is quite commonly used in the simplification of GPS data. (http://en.wikipedia.org/wiki/Ramer-Douglas-Peucker_algorithm)

I agree with the other answerers that in most cases (almost always) it is necessary to sanitize Your input.

But consider such code (it is for a REST controller):

$method = $_SERVER['REQUEST_METHOD'];

switch ($method) {
            case 'GET':
                return $this->doGet($request, $object);
            case 'POST':
                return $this->doPost($request, $object);
            case 'PUT':
                return $this->doPut($request, $object);
            case 'DELETE':
                return $this->doDelete($request, $object);
            default:
                return $this->onBadRequest();
}

It would not be very useful to apply sanitizing here (although it would not break anything, either).

So, follow recommendations, but not blindly - rather understand why they are for :)

Update Java 8 usage of default keyword: As many others have noted The default visibility (no keyword)

the field will be accessible from inside the same package to which the class belongs.

Not to be confused with the new Java 8 feature (Default Methods) that allows an interface to provide an implementation when its labeled with the default keyword.

See: Access modifiers

Ctrl + Shift + O (<-- an 'O' not a zero)

Note: This shortcut also removes unused imports.

also this should work (not tested):

SELECT u.* FROM room u JOIN facilities_r fu ON fu.id_uc = u.id_uc AND u.id_fu IN(4,3) WHERE 1 AND vizibility = 1 GROUP BY id_uc ORDER BY u_premium desc , id_uc desc

If u.id_fu is a numeric field then you can remove the ' around them. The same for vizibility. Only if the field is a text field (data type char, varchar or one of the text-datatype e.g. longtext) then the value has to be enclosed by ' or even ".

Also I and Oracle too recommend to enclose table and field names in backticks. So you won't get into trouble if a field name contains a keyword.

The simplest solution is: Create a CSS file and type this:

.btn:focus, .btn:active:focus, .btn.active:focus {
    box-shadow: none !important;
}

One way to do this would be to pass the instance of ParentClass to the ChildClass on construction

public ChildClass
{
    private ParentClass parent;

    public ChildClass(ParentClass parent)
    {
        this.parent = parent;
    }

    public void LoadData(DateTable dt)
    {
       // do something
       parent.CurrentRow++; // or whatever.
       parent.UpdateProgressBar(); // Call the method
    }
}

Make sure to pass the reference to this when constructing ChildClass inside parent:

if(loadData){

     ChildClass childClass = new ChildClass(this); // here

     childClass.LoadData(this.Datatable);

}

Caveat: This is probably not the best way to organise your classes, but it directly answers your question.

EDIT: In the comments you mention that more than 1 parent class wants to use ChildClass. This is possible with the introduction of an interface, eg:

public interface IParentClass
{
    void UpdateProgressBar();
    int CurrentRow{get; set;}
}

Now, make sure to implement that interface on both (all?) Parent Classes and change child class to this:

public ChildClass
{
    private IParentClass parent;

    public ChildClass(IParentClass parent)
    {
        this.parent = parent;
    }

    public void LoadData(DateTable dt)
    {
       // do something
       parent.CurrentRow++; // or whatever.
       parent.UpdateProgressBar(); // Call the method
    }
}

Now anything that implements IParentClass can construct an instance of ChildClass and pass this to its constructor.

Some of the other answers return an actual string whereas I had more need to know the actual index int. And the answers that do that seem to over-complicate things. Using some of the other answers as inspiration, I did the following...

First, I created a function:

CREATE FUNCTION [dbo].[LastIndexOf] (@stringToFind varchar(max), @stringToSearch varchar(max))
RETURNS INT
AS
BEGIN
    RETURN (LEN(@stringToSearch) - CHARINDEX(@stringToFind,REVERSE(@stringToSearch))) + 1
END
GO

Then, in your query you can simply do this:

declare @stringToSearch varchar(max) = 'SomeText: SomeMoreText: SomeLastText'

select dbo.LastIndexOf(':', @stringToSearch)

The above should return 23 (the last index of ':')

Hope this made it a little easier for someone!

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

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

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

As others have noted, getting the hostname based on DNS resolution is unreliable.

Since this question is unfortunately still relevant in 2018, I'd like to share with you my network-independent solution, with some test runs on different systems.

The following code tries to do the following:

• On Windows

  1. Read the COMPUTERNAME environment variable through System.getenv().

  2. Execute hostname.exe and read the response

• On Linux

  1. Read the HOSTNAME environment variable through System.getenv()

  2. Execute hostname and read the response

  3. Read /etc/hostname (to do this I'm executing cat since the snippet already contains code to execute and read. Simply reading the file would be better, though).

The code:

public static void main(String[] args) throws IOException {
    String os = System.getProperty("os.name").toLowerCase();

    if (os.contains("win")) {
        System.out.println("Windows computer name through env:\"" + System.getenv("COMPUTERNAME") + "\"");
        System.out.println("Windows computer name through exec:\"" + execReadToString("hostname") + "\"");
    } else if (os.contains("nix") || os.contains("nux") || os.contains("mac os x")) {
        System.out.println("Unix-like computer name through env:\"" + System.getenv("HOSTNAME") + "\"");
        System.out.println("Unix-like computer name through exec:\"" + execReadToString("hostname") + "\"");
        System.out.println("Unix-like computer name through /etc/hostname:\"" + execReadToString("cat /etc/hostname") + "\"");
    }
}

public static String execReadToString(String execCommand) throws IOException {
    try (Scanner s = new Scanner(Runtime.getRuntime().exec(execCommand).getInputStream()).useDelimiter("\\A")) {
        return s.hasNext() ? s.next() : "";
    }
}

Results for different operating systems:

macOS 10.13.2

Unix-like computer name through env:"null"
Unix-like computer name through exec:"machinename
"
Unix-like computer name through /etc/hostname:""

OpenSuse 13.1

Unix-like computer name through env:"machinename"
Unix-like computer name through exec:"machinename
"
Unix-like computer name through /etc/hostname:""

Ubuntu 14.04 LTS This one is kinda strange since echo $HOSTNAME returns the correct hostname, but System.getenv("HOSTNAME") does not:

Unix-like computer name through env:"null"
Unix-like computer name through exec:"machinename
"
Unix-like computer name through /etc/hostname:"machinename
"

EDIT: According to legolas108, System.getenv("HOSTNAME") works on Ubuntu 14.04 if you run export HOSTNAME before executing the Java code.

Windows 7

Windows computer name through env:"MACHINENAME"
Windows computer name through exec:"machinename
"

Windows 10

Windows computer name through env:"MACHINENAME"
Windows computer name through exec:"machinename
"

The machine names have been replaced but I kept the capitalization and structure. Note the extra newline when executing hostname, you might have to take it into account in some cases.

I had this error because I wrote a wrong Class-Path in my MANIFEST.MF

As per documentation:

If you are accessing scoped beans within Spring Web MVC, i.e. within a request that is processed by the Spring DispatcherServlet, or DispatcherPortlet, then no special setup is necessary: DispatcherServlet and DispatcherPortlet already expose all relevant state.

If you are runnning outside of Spring MVC ( Not processed by DispatchServlet) you have to use the RequestContextListener Not just ContextLoaderListener .

Add the following in your web.xml

   <listener>
            <listener-class>
                    org.springframework.web.context.request.RequestContextListener 
            </listener-class>
    </listener>        

That will provide session to Spring in order to maintain the beans in that scope

Update : As per other answers , the @Controller only sensible when you are with in Spring MVC Context, So the @Controller is not serving actual purpose in your code. Still you can inject your beans into any where with session scope / request scope ( you don't need Spring MVC / Controller to just inject beans in particular scope) .

Update : RequestContextListener exposes the request to the current Thread only.
You have autowired ReportBuilder in two places

1. ReportPage - You can see Spring injected the Report builder properly here, because we are still in Same web Thread. i did changed the order of your code to make sure the ReportBuilder injected in ReportPage like this.

log.info("ReportBuilder name: {}", reportBuilder.getName());
reportController.getReportData();

i knew the log should go after as per your logic , just for debug purpose i added .

2. UselessTasklet - We got exception , here because this is different thread created by Spring Batch , where the Request is not exposed by RequestContextListener.

You should have different logic to create and inject ReportBuilder instance to Spring Batch ( May Spring Batch Parameters and using Future<ReportBuilder> you can return for future reference)

Objective c

This only works in Xcode 7

Go to .h file and import AVKit/AVKit.h and AVFoundation/AVFoundation.h. Then go .m file and add this code:

NSURL *url=[[NSBundle mainBundle]URLForResource:@"arreg" withExtension:@"mp4"];
AVPlayer *video=[AVPlayer playerWithURL:url];
AVPlayerViewController *controller=[[AVPlayerViewController alloc]init];
controller.player=video;
[self.view addSubview:controller.view];
controller.view.frame=self.view.frame;
[self addChildViewController:controller];
[video play];

YML definition:

dir:
  default: /home/data/in/
  proj1: ${dir.default}p1
  proj2: ${dir.default}p2
  proj3: ${dir.default}p3 

Somewhere in thymeleaf

<p th:utext='${@environment.getProperty("dir.default")}' />
<p th:utext='${@environment.getProperty("dir.proj1")}' /> 

Output: /home/data/in/ /home/data/in/p1

Here's a ES6 using Await / Async example:

    async deleteProduct(id) {

        if (!id) {
            return {msg: 'No Id specified..', payload: 1};
        }

        try {
            return !!await products.destroy({
                where: {
                    id: id
                }
            });
        } catch (e) {
            return false;
        }

    }

Please note that I'm using the !! Bang Bang Operator on the result of the await which will change the result into a Boolean.

You should be able to use \n inside a Swift string, and it should work as expected, creating a newline character. You will want to remove the space after the \n for proper formatting like so:

var example: String = "Hello World \nThis is a new line"

Which, if printed to the console, should become:

Hello World
This is a new line

However, there are some other considerations to make depending on how you will be using this string, such as:

• If you are setting it to a UILabel's text property, make sure that the UILabel's numberOfLines = 0, which allows for infinite lines.
• In some networking use cases, use \r\n instead, which is the Windows newline.

Edit: You said you're using a UITextField, but it does not support multiple lines. You must use a UITextView.

You can use the row_number() function for this.

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
            row_number() over (order by (select NULL))
    FROM PM_Ingrediants 
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

If you want to start with the maximum already in the table then do:

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
           coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
    FROM PM_Ingrediants cross join
         (select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

Finally, you can just make the sequence column an auto-incrementing identity column. This saves the need to increment it each time:

create table PM_Ingrediants_Arrangement_Temp ( . . .
    sequence int identity(1, 1) -- and might consider making this a primary key too
    . . .
)

You can create an ExpandoObject like this:

IDictionary<string,object> expando = new ExpandoObject();
expando["Name"] = value;

And after casting it to dynamic, those values will look like properties:

dynamic d = expando;
Console.WriteLine(d.Name);

However, they are not actual properties and cannot be accessed using Reflection. So the following statement will return a null:

d.GetType().GetProperty("Name") 

I used the above command line as follow: update TABLE-NAME set FIELD = replace(FIELD, 'And', 'and'); the purpose was to replace And with and ("A" should be lowercase). The problem is it cannot find the "And" in database, but if I use like "%And%" then it can find it along with many other ands that are part of a word or even the ones that are already lowercase.

On Ubuntu you can enable a cron.log file to contain just the CRON entries.

Uncomment the line that mentions cron in /etc/rsyslog.d/50-default.conf file:

#  Default rules for rsyslog.
#

#                       For more information see rsyslog.conf(5) and /etc/rsyslog.conf

#
# First some standard log files.  Log by facility.
#
auth,authpriv.*                 /var/log/auth.log
*.*;auth,authpriv.none          -/var/log/syslog
#cron.*                          /var/log/cron.log

Save and close the file and then restart the rsyslog service:

sudo systemctl restart rsyslog

You can now see cron log entries in its own file:

sudo tail -f /var/log/cron.log

Sample outputs:

Jul 18 07:05:01 machine-host-name CRON[13638]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1)

However, you will not see more information about what scripts were actually run inside /etc/cron.daily or /etc/cron.hourly, unless those scripts direct output to the cron.log (or perhaps to some other log file).

If you want to verify if a crontab is running and not have to search for it in cron.log or syslog, create a crontab that redirects output to a log file of your choice - something like:

# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
30 2 * * 1 /usr/local/sbin/certbot-auto renew >> /var/log/le-renew.log 2>&1

What moves origin/HEAD "organically"?

• git clone sets it once to the spot where HEAD is on origin
  • it serves as the default branch to checkout after cloning with git clone

What does HEAD on origin represent?

• on bare repositories (often repositories “on servers”) it serves as a marker for the default branch, because git clone uses it in such a way
• on non-bare repositories (local or remote), it reflects the repository’s current checkout

What sets origin/HEAD?

• git clone fetches and sets it
• it would make sense if git fetch updates it like any other reference, but it doesn’t
• git remote set-head origin -a fetches and sets it
  • useful to update the local knowledge of what remote considers the “default branch”

Trivia

• origin/HEAD can also be set to any other value without contacting the remote: git remote set-head origin <branch>
  • I see no use-case for this, except for testing
• unfortunately nothing is able to set HEAD on the remote
• older versions of git did not know which branch HEAD points to on the remote, only which commit hash it finally has: so it just hopefully picked a branch name pointing to the same hash

An accessed dictionary value (a list in this case) is the original value, separate from the dictionary which is used to access it. You would increment the values in the list the same way whether it's in a dictionary or not:

l = dictionary.get('C1')
for i in range(len(l)):
    l[i] += 10

I always use:

__location__ = os.path.realpath(
    os.path.join(os.getcwd(), os.path.dirname(__file__)))

The join() call prepends the current working directory, but the documentation says that if some path is absolute, all other paths left of it are dropped. Therefore, getcwd() is dropped when dirname(__file__) returns an absolute path.

Also, the realpath call resolves symbolic links if any are found. This avoids troubles when deploying with setuptools on Linux systems (scripts are symlinked to /usr/bin/ -- at least on Debian).

You may the use the following to open up files in the same folder:

f = open(os.path.join(__location__, 'bundled-resource.jpg'))
# ...

I use this to bundle resources with several Django application on both Windows and Linux and it works like a charm!

java -DLOG_DIR=${LOG_DIR} -jar myjar.jar "param1" "param2" ==> in cmd line if you have "value="${LOG_DIR}/log/clientProject/project-error.log" in xml

npm ls

npm list is just an alias for npm ls

For the extended info use

npm la    
npm ll

You can always set --depth=0 at the end to get the first level deep.

npm ls --depth=0

You can check development and production packages.

npm ls --only=dev
npm ls --only=prod

To show the info in json format

npm ls --json=true

The default is false

npm ls --json=false

You can insist on long format to show extended information.

npm ls --long=true

You can show parseable output instead of tree view.

npm ls --parseable=true

You can list packages in the global install prefix instead of in the current project.

npm ls --global=true
npm ls -g // shorthand

Full documentation you can find here.

If, like me, you want to make a function pack or something that people can download then it's very simple. Just write your function in a python file and save it as the name you want IN YOUR PYTHON DIRECTORY. Now, in your script where you want to use this, you type:

from FILE NAME import FUNCTION NAME

Note - the parts in capital letters are where you type the file name and function name.

Now you just use your function however it was meant to be.

Example:

FUNCTION SCRIPT - saved at C:\Python27 as function_choose.py

def choose(a):
  from random import randint
  b = randint(0, len(a) - 1)
  c = a[b]
  return(c)

SCRIPT USING FUNCTION - saved wherever

from function_choose import choose
list_a = ["dog", "cat", "chicken"]
print(choose(list_a))

OUTPUT WILL BE DOG, CAT, OR CHICKEN

Hoped this helped, now you can create function packs for download!

JSON in Java has some great resources.

Maven dependency:

<dependency>
  <groupId>org.json</groupId>
  <artifactId>json</artifactId>
  <version>20180813</version>
</dependency>

XML.java is the class you're looking for:

import org.json.JSONObject;
import org.json.XML;
import org.json.JSONException;

public class Main {

    public static int PRETTY_PRINT_INDENT_FACTOR = 4;
    public static String TEST_XML_STRING =
        "<?xml version=\"1.0\" ?><test attrib=\"moretest\">Turn this to JSON</test>";

    public static void main(String[] args) {
        try {
            JSONObject xmlJSONObj = XML.toJSONObject(TEST_XML_STRING);
            String jsonPrettyPrintString = xmlJSONObj.toString(PRETTY_PRINT_INDENT_FACTOR);
            System.out.println(jsonPrettyPrintString);
        } catch (JSONException je) {
            System.out.println(je.toString());
        }
    }
}

Output is:

{"test": {
    "attrib": "moretest",
    "content": "Turn this to JSON"
}}

Code to avoid returning an empty string ( when input is like "00000").

string myStr = "00012345";
myStr = myStr.TrimStart('0');
myStr = myStr.Length > 0 ? myStr : "0";

If you mean to change default directory for "Node.js command prompt", when you launch it, then (Windows case)

1. go the directory where NodeJS was installed
2. find file nodevars.bat
3. open it with editor as administrator

4. change the default path in the row which looks like

   if "%CD%\"=="%~dp0" cd /d "%HOMEDRIVE%%HOMEPATH%"
   

with your path. It could be for example

    if "%CD%\"=="%~dp0" cd /d "c://MyDirectory/"

if you mean to change directory once when you launched "Node.js command prompt", then execute the following command in the Node.js command prompt:

     cd c:/MyDirectory/

Another option you can go with here:

df.loc["Total", "MyColumn"] = df.MyColumn.sum()

#         X  MyColumn      Y       Z
#0        A     84.0    13.0    69.0
#1        B     76.0    77.0   127.0
#2        C     28.0    69.0    16.0
#3        D     28.0    28.0    31.0
#4        E     19.0    20.0    85.0
#5        F     84.0   193.0    70.0
#Total  NaN    319.0     NaN     NaN

You can also use append() method:

df.append(pd.DataFrame(df.MyColumn.sum(), index = ["Total"], columns=["MyColumn"]))

Update:

In case you need to append sum for all numeric columns, you can do one of the followings:

Use append to do this in a functional manner (doesn't change the original data frame):

# select numeric columns and calculate the sums
sums = df.select_dtypes(pd.np.number).sum().rename('total')

# append sums to the data frame
df.append(sums)
#         X  MyColumn      Y      Z
#0        A      84.0   13.0   69.0
#1        B      76.0   77.0  127.0
#2        C      28.0   69.0   16.0
#3        D      28.0   28.0   31.0
#4        E      19.0   20.0   85.0
#5        F      84.0  193.0   70.0
#total  NaN     319.0  400.0  398.0

Use loc to mutate data frame in place:

df.loc['total'] = df.select_dtypes(pd.np.number).sum()
df
#         X  MyColumn      Y      Z
#0        A      84.0   13.0   69.0
#1        B      76.0   77.0  127.0
#2        C      28.0   69.0   16.0
#3        D      28.0   28.0   31.0
#4        E      19.0   20.0   85.0
#5        F      84.0  193.0   70.0
#total  NaN     638.0  800.0  796.0

Wrap the text in a span and set visibility:hidden; Visibility hidden will hide the element but it will still take up the same space on the page (conversely display: none removes it from the page as well).

as i also wanted that same thing in a project u can do something like

HTML

<div class="col-md-6"></div>
<div class="divider-vertical"></div>
<div class="col-md-5"></div>

CSS

.divider-vertical {
    height: 100px;                   /* any height */
    border-left: 1px solid gray;     /* right or left is the same */
    float: left;                     /* so BS grid doesn't break */
    opacity: 0.5;                    /* optional */
    margin: 0 15px;                  /* optional */
}

LESS

.divider-vertical(@h:100, @opa:1, @mar:15) {
    height: unit(@h,px);             /* change it to rem,em,etc.. */
    border-left: 1px solid gray;
    float: left;
    opacity: @opa;
    margin: 0 unit(@mar,px);         /* change it to rem,em,etc.. */
}

The AAR file consists of a JAR file and some resource files (it is basically a standard zip file with a custom file extension). Here are the steps to convert:

1. Extract the AAR file using standard zip extract (rename it to *.zip to make it easier)
2. Find the classes.jar file in the extracted files
3. Rename it as you like and use that jar file in your project

Inside a module

Option Explicit
dim objExcelApp as Excel.Application
dim wb as Excel.Workbook

sub Initialize()
   set objExcelApp = new Excel.Application
end sub

sub ProcessDataWorkbook()
    dim ws as Worksheet
    set wb = objExcelApp.Workbooks.Open("path to my workbook")
    set ws = wb.Sheets(1)

    ws.Cells(1,1).Value = "Hello"
    ws.Cells(1,2).Value = "World"

    'Close the workbook
    wb.Close
    set wb = Nothing
end sub

sub Release()
   set objExcelApp = Nothing
end sub

recyclerView.removeAllViewsInLayout();

The above line would help you remove all views from the layout.

For you:

@Override
protected void onRestart() {
    super.onRestart();

    recyclerView.removeAllViewsInLayout(); //removes all the views

    //then reload the data
    PostCall doPostCall = new PostCall(); //my AsyncTask... 
    doPostCall.execute();
}

If you do have a legitimate need to run some js from a partial, here's how you could do it, jQuery is required:

<script type="text/javascript">        
    function scriptToExecute()
    {
        //The script you want to execute when page is ready.           
    }

    function runWhenReady()
    {
        if (window.$)
            scriptToExecute();                                   
        else
            setTimeout(runWhenReady, 100);
    }
    runWhenReady();
</script>

Here's a general procedure for producing a random number in a specified range:

int randInRange(int min, int max)
{
  return min + (int) (rand() / (double) (RAND_MAX + 1) * (max - min + 1));
}

Depending on the PRNG algorithm being used, the % operator may result in a very non-random sequence of numbers.

What you have is a parse error. Those are thrown before any code is executed. A PHP file needs to be parsed in its entirety before any code in it can be executed. If there's a parse error in the file where you're setting your error levels, they won't have taken effect by the time the error is thrown.

Either break your files up into smaller parts, like setting the error levels in one file and then includeing another file which contains the actual code (and errors), or set the error levels outside PHP using php.ini or .htaccess directives.

This problem also arise when we don't give the single or double quotes to the database value.

Wrong way:

$query ="INSERT INTO tabel_name VALUE ($value1,$value2)";

As database inserting values must be in quotes ' '/" "

Right way:

$query ="INSERT INTO STUDENT VALUE ('$roll_no','$name','$class')";

Overwriting console.log is the way to go. But for it to work in required modules, you also need to export it.

module.exports = console;

To save yourself the trouble of writing log files, rotating and stuff, you might consider using a simple logger module like winston:

// Include the logger module
var winston = require('winston');
// Set up log file. (you can also define size, rotation etc.)
winston.add(winston.transports.File, { filename: 'somefile.log' });
// Overwrite some of the build-in console functions
console.error = winston.error;
console.log = winston.info;
console.info = winston.info;
console.debug = winston.debug;
console.warn = winston.warn;
module.exports = console;

You can do that in this way:

ORDER BY `products`.`product_category_id` DESC ,`naam` ASC

Have a look at ORDER BY Optimization

.g-recaptcha{
    -moz-transform:scale(1.1);
    -ms-transform:scale(1.1); 
    -o-transform:scale(1.1); 
    -moz-transform-origin:0; 
    -ms-transform-origin:0;
    -o-transform-origin:0;

    transform:scale(1.1);

    filter: progid:DXImageTransform.Microsoft.Matrix(M11=1.1,M12=0,M21=0,M22=1.1,SizingMethod='auto expand');
}

Another option is the SimpleXML extension (I believe it comes standard with most php installs.)

http://php.net/manual/en/book.simplexml.php

The syntax looks something like this for your example

$xml = new SimpleXMLElement($xmlString);
echo $xml->bbb->cccc->dddd['Id'];
echo $xml->bbb->cccc->eeee['name'];
// or...........
foreach ($xml->bbb->cccc as $element) {
  foreach($element as $key => $val) {
   echo "{$key}: {$val}";
  }
}

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

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

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

From my experience, I used GridLayout.

    thePanel.setLayout(new GridLayout(a,b,c,d));

a = row number, b = column number, c = horizontal gap, d = vertical gap.

For example, if I want to create panel with:

• unlimited row (set a = 0)
• 1 column (set b = 1)
• vertical gap= 3 (set d = 3)

The code is below:

    thePanel.setLayout(new GridLayout(0,1,0,3));

This method is useful when you want to add JScrollPane to your JPanel. Size of the JPanel inside JScrollPane will automatically changes when you add some components on it, so the JScrollPane will automatically reset the scroll bar.

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note the point density in proportional to inverse square of the radius, hence instead of picking r from [0, r_max], pick from [0, r_max^2], then compute your coordinates as:

x = sqrt(r) * cos(angle)
y = sqrt(r) * sin(angle)

This will give you uniform point distribution on a disk.

Here is a detailed information on setting up Java and its paths on CentOS6.

Below steps are for the installation of latest Java version 8:

1. Download java rpm package from Oracle site. (jdk-8-linux-x64.rpm)
2. Install from the rpm. (rpm -Uvh jdk-8-linux-x64.rpm)
3. Open /etc/profile, and set the java paths, save it.
4. Check the java installation path, and java version, with the commands: which java, java -version

Now you can test the installation with a sample java program

I found easier to do it like this:

export GOROOT=$HOME/go
export GOPATH=$GOROOT/bin
export PATH=$PATH:$GOPATH

Try this:

SCRIPT:

function winOpen()
{
    window.open("yourpage.jsp");
}

HTML:

<a href="javascript:;" onclick="winOpen()">Pop Up</a>

Read https://developer.mozilla.org/en/docs/DOM/window.open for window.open

Define a class for key definition in your group.

class KeyObj {

    ArrayList<Object> keys;

    public KeyObj( Object... objs ) {
        keys = new ArrayList<Object>();

        for (int i = 0; i < objs.length; i++) {
            keys.add( objs[i] );
        }
    }

    // Add appropriate isEqual() ... you IDE should generate this

}

Now in your code,

peopleByManyParams = people
            .collect(Collectors.groupingBy(p -> new KeyObj( p.age, p.other1, p.other2 ), Collectors.mapping((Person p) -> p, toList())));

Try this when your application still demands $parse, $eval, $watch like behavior in Angular

https://github.com/vinayk406/angular-expression-parser

Optional parameters are kind of like a macro substitution from what I understand. They are not really optional from the method's point of view. An artifact of that is the behavior you see where you get different results if you cast to an interface.

am not sure if I fully understand the issue, but guess it's related to the one I had, am using Qt with TCP socket communication, all non-blocking, both Windows and Linux..

wanted to get a quick notification when an already connected client failed or completely disappeared, and not waiting the default 900+ seconds until the disconnect signal got raised. The trick to get this working was to set the TCP_USER_TIMEOUT socket option of the SOL_TCP layer to the required value, given in milliseconds.

this is a comparably new option, pls see http://tools.ietf.org/html/rfc5482, but apparently it's working fine, tried it with WinXP, Win7/x64 and Kubuntu 12.04/x64, my choice of 10 s turned out to be a bit longer, but much better than anything else I've tried before ;-)

the only issue I came across was to find the proper includes, as apparently this isn't added to the standard socket includes (yet..), so finally I defined them myself as follows:

#ifdef WIN32
    #include <winsock2.h>
#else
    #include <sys/socket.h>
#endif

#ifndef SOL_TCP
    #define SOL_TCP 6  // socket options TCP level
#endif
#ifndef TCP_USER_TIMEOUT
    #define TCP_USER_TIMEOUT 18  // how long for loss retry before timeout [ms]
#endif

setting this socket option only works when the client is already connected, the lines of code look like:

int timeout = 10000;  // user timeout in milliseconds [ms]
setsockopt (fd, SOL_TCP, TCP_USER_TIMEOUT, (char*) &timeout, sizeof (timeout));

and the failure of an initial connect is caught by a timer started when calling connect(), as there will be no signal of Qt for this, the connect signal will no be raised, as there will be no connection, and the disconnect signal will also not be raised, as there hasn't been a connection yet..

I am using a regex to make sure that I only allow letters, number and a space

Then it is as simple as adding a space to what you've already got:

$newtag = preg_replace("/[^a-zA-Z0-9 ]/", "", $tag);

(note, I removed the s| which seemed unintentional? Certainly the s was redundant; you can restore the | if you need it)

If you specifically want *a* space, as in only a single one, you will need a more complex expression than this, and might want to consider a separate non-regex piece of logic.

The PHPMailer help docs on this specific error helped to get me on the right path.

What we found is that php.ini did not have the sendmail_path defined, so I added that with sendmail_path = /usr/sbin/sendmail -t -i;

I got that error, when sometimes I type in Chinese language. When it comes to punctuation marks, you do not notice that you are actually typing the Chinese version, instead of the English version.

The interpreter will give you an error message, but for human eyes, it is hard to notice the difference.

For example, "," in Chinese; and "," in English. So be careful with your language setting.

If you want to keep using the Array.prototype.include() in javascript you can use this script: github-script-ie-include That converts automatically the include() to the match() function if it detects IE.

Other option is using always thestring.match(Regex(expression))

You can set background color to All Scaffolds in application at once.

just set scaffoldBackgroundColor: in ThemeData

 MaterialApp(
      title: 'Flutter Demo',
      theme: new ThemeData(scaffoldBackgroundColor: const Color(0xFFEFEFEF)),
      home: new MyHomePage(title: 'Flutter Demo Home Page'),
    );

Check that you closed your class.

For example, if you have controller class with methods, and by accident you delete the final bracket, which close whole class, you will get this error.

class someControler{
private $varr;
public $varu;
..
public function method {
..
} 
..
}// if you forget to close the controller, you will get the error

about theutz answer , there is no need to specify the IMapper mapper parrameter at the controllers constructor.

you can use the Mapper as it is a static member at any place of the code.

public class UserController : Controller {
   public someMethod()
   {
      Mapper.Map<User, UserDto>(user);
   }
}

You need to move the pointer to the first row, before asking for data:

result.beforeFirst();
result.next();
String foundType = result.getString(1);

I faced the same problem and now found a way to solve it. First you have to delete the database of the user that you wish to drop. Then the user can be easily deleted.

I created an user named "msf" and struggled a while to delete the user and recreate it. I followed the below steps and Got succeeded.

1) Drop the database

dropdb msf

2) drop the user

dropuser msf

Now I got the user successfully dropped.

For Xcode 6.3:

 cell.selectionStyle = UITableViewCellSelectionStyle.None;

You can use id(name) to check if two names represent the same object:

>>> a = b = c = [0, 3, 5]
>>> print(id(a), id(b), id(c))
46268488 46268488 46268488

Lists are mutable; it means you can change the value in place without creating a new object. However, it depends on how you change the value:

>>> a[0] = 1
>>> print(id(a), id(b), id(c))
46268488 46268488 46268488
>>> print(a, b, c)
[1, 3, 5] [1, 3, 5] [1, 3, 5]

If you assign a new list to a, then its id will change, so it won't affect b and c's values:

>>> a = [1, 8, 5]
>>> print(id(a), id(b), id(c))
139423880 46268488 46268488
>>> print(a, b, c)
[1, 8, 5] [1, 3, 5] [1, 3, 5]

Integers are immutable, so you cannot change the value without creating a new object:

>>> x = y = z = 1
>>> print(id(x), id(y), id(z))
507081216 507081216 507081216
>>> x = 2
>>> print(id(x), id(y), id(z))
507081248 507081216 507081216
>>> print(x, y, z)
2 1 1

You can actually chain multiple $lookup stages. Based on the names of the collections shared by profesor79, you can do this :

db.sivaUserInfo.aggregate([
    {
        $lookup: {
           from: "sivaUserRole",
           localField: "userId",
           foreignField: "userId",
           as: "userRole"
        }
    },
    {
        $unwind: "$userRole"
    },
    {
        $lookup: {
            from: "sivaUserInfo",
            localField: "userId",
            foreignField: "userId",
            as: "userInfo"
        }
    },
    {
        $unwind: "$userInfo"
    }
])

This will return the following structure :

{
    "_id" : ObjectId("56d82612b63f1c31cf906003"),
    "userId" : "AD",
    "phone" : "0000000000",
    "userRole" : {
        "_id" : ObjectId("56d82612b63f1c31cf906003"),
        "userId" : "AD",
        "role" : "admin"
    },
    "userInfo" : {
        "_id" : ObjectId("56d82612b63f1c31cf906003"),
        "userId" : "AD",
        "phone" : "0000000000"
    }
}

Maybe this could be considered an anti-pattern because MongoDB wasn't meant to be relational but it is useful.

Clearly you aren't sending the data with ObjectOutputStream: you are just writing the bytes.

• If you read with readObject() you must write with writeObject().
• If you read with readUTF() you must write with writeUTF().
• If you read with readXXX() you must write with writeXXX(), for most values of XXX.

As Geoff says, what Crockford says is good.

The only exception I follow (and have seen widely used) is to use $varname to indicate a jQuery (or whatever library) object. E.g.

var footer = document.getElementById('footer');

var $footer = $('#footer');

In MonoTouch:

To get the Major version use:

UIDevice.CurrentDevice.SystemVersion.Split('.')[0]

For minor version use:

UIDevice.CurrentDevice.SystemVersion.Split('.')[1]

If you need to clear the NuGet cache for your build server/agent you can find the cache for NuGet packages here:

%windir%/ServiceProfiles/[account under build service runs]\AppData\Local\NuGet\Cache

Example:

C:\Windows\ServiceProfiles\NetworkService\AppData\Local\NuGet\Cache

In case it helps others, the option I prefer, which is not listed here, uses Guava's Maps functionality:

public enum Vebosity {
    BRIEF("BRIEF"),
    NORMAL("NORMAL"),
    FULL("FULL");

    private String value;
    private Verbosity(final String value) {
        this.value = value;
    }

    public String getValue() {
        return this.value;
    }

    private static ImmutableMap<String, Verbosity> reverseLookup = 
            Maps.uniqueIndex(Arrays.asList(Verbosity.values()), Verbosity::getValue);

    public static Verbosity fromString(final String id) {
        return reverseLookup.getOrDefault(id, NORMAL);
    }
}

With the default you can use null, you can throw IllegalArgumentException or your fromString could return an Optional, whatever behavior you prefer.

you would have to write down some method to create a temporary array and then copy it like

public String[] increaseArray(String[] theArray, int increaseBy)  
{  
    int i = theArray.length;  
    int n = ++i;  
    String[] newArray = new String[n];  
    for(int cnt=0;cnt<theArray.length;cnt++)
    {  
        newArray[cnt] = theArray[cnt];  
    }  
    return newArray;  
}  

or The ArrayList would be helpful to resolve your problem.

&& == logical AND

& = bitwise AND

In both: Anaconda prompt and the old cmd.exe, you change your directory by first changing to the drive you want, by simply writing its name followed by a ':', exe: F: , which will take you to the drive named 'F' on your machine. Then using the command cd to navigate your way inside that drive as you normally would.

Try this:

string filename = @"C:/folder1/folder2/file.txt";
string FolderName = new DirectoryInfo(System.IO.Path.GetDirectoryName(filename)).Name;

if you just scrollheight it will make a problem when user will want to see his previous message. so you need to make something that when new message come only then the code. use jquery latest version. 1.here I checked the height before message loaded. 2. again check the new height. 3. if the height is different only that time it will scroll otherwise it will not scroll. 4. not in the if condition you can put any ringtone or any other feature that you need. that will play when new message will come. thanks

var oldscrollHeight = $("#messages").prop("scrollHeight");
$.get('msg_show.php', function(data) {
    div.html(data);
    var newscrollHeight = $("#messages").prop("scrollHeight"); //Scroll height after the request
    if (newscrollHeight > oldscrollHeight) {
        $("#messages").animate({
            scrollTop: newscrollHeight
        }, 'normal'); //Autoscroll to bottom of div
    }

Boost has a macro that will do this for you.

http://www.boost.org/doc/libs/1_44_0/doc/html/foreach.html

If you used read.table() (or one of it's ilk, e.g. read.csv()) then the easy fix is to change the call to:

read.table(file = "foo.txt", row.names = 1, ....)

where .... are the other arguments you needed/used. The row.names argument takes the column number of the data file from which to take the row names. It need not be the first column. See ?read.table for details/info.

If you already have the data in R and can't be bothered to re-read it, or it came from another route, just set the rownames attribute and remove the first variable from the object (assuming obj is your object)

rownames(obj) <- obj[, 1]  ## set rownames
obj <- obj[, -1]           ## remove the first variable

If you are using a webkit browser you can change the color of the caret by following the next CSS snippet. I'm not sure if It's possible to change the format with CSS.

input,
textarea {
    font-size: 24px;
    padding: 10px;
    
    color: red;
    text-shadow: 0px 0px 0px #000;
    -webkit-text-fill-color: transparent;
}

input::-webkit-input-placeholder,
textarea::-webkit-input-placeholder {
    color:
    text-shadow: none;
    -webkit-text-fill-color: initial;
}

As Sagiv b.g. pointed out, the npm start command is a shortcut for npm run start. I just wanted to add a real-life example to clarify it a bit more.

The setup below comes from the create-react-app github repo. The package.json defines a bunch of scripts which define the actual flow.

"scripts": {
  "start": "npm-run-all -p watch-css start-js",
  "build": "npm run build-css && react-scripts build",
  "watch-css": "npm run build-css && node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/ --watch --recursive",
  "build-css": "node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/",
  "start-js": "react-scripts start"
},

For clarity, I added a diagram.

The blue boxes are references to scripts, all of which you could executed directly with an npm run <script-name> command. But as you can see, actually there are only 2 practical flows:

• npm run start
• npm run build

The grey boxes are commands which can be executed from the command line.

So, for instance, if you run npm start (or npm run start) that actually translate to the npm-run-all -p watch-css start-js command, which is executed from the commandline.

In my case, I have this special npm-run-all command, which is a popular plugin that searches for scripts that start with "build:", and executes all of those. I actually don't have any that match that pattern. But it can also be used to run multiple commands in parallel, which it does here, using the -p <command1> <command2> switch. So, here it executes 2 scripts, i.e. watch-css and start-js. (Those last mentioned scripts are watchers which monitor file changes, and will only finish when killed.)

• The watch-css makes sure that the *.scss files are translated to *.cssfiles, and looks for future updates.

• The start-js points to the react-scripts start which hosts the website in a development mode.

In conclusion, the npm start command is configurable. If you want to know what it does, then you have to check the package.json file. (and you may want to make a little diagram when things get complicated).

enter image description here The XPath text() function locates elements within a text node while dot (.) locate elements inside or outside a text node. In the image description screenshot, the XPath text() function will only locate Success in DOM Example 2. It will not find success in DOM Example 1 because it's located between the tags.

In addition, the text() function will not find success in DOM Example 3 because success does not have a direct relationship to the element . Here's a video demo explaining the difference between text() and dot (.) https://youtu.be/oi2Q7-0ZIBg

jQuery now supports .data();, so if you have

<div id='author' data-content='stuff!'>

use

var author = $('#author').data("content"); // author = 'stuff!'

When converting SVG to transparent PNG, don't forget to put this BEFORE $imagick->readImageBlob():

$imagick->setBackgroundColor(new ImagickPixel('transparent'));

If a remote URL is provided, content will be loaded one time via jQuery's load method and injected into the .modal-content div. If you're using the data-api, you may alternatively use the href attribute to specify the remote source. An example of this is shown below

$.ajaxSetup ({
    // Disable caching of AJAX responses
    cache: false
});

Try this, you will know the difference between change and modify,

ALTER TABLE table_name CHANGE curr_column_name new_column_name new_column_datatype [constraints]

ALTER TABLE table_name MODIFY column_name new_column_datatype [constraints]

• You can change name and datatype of the particular column using CHANGE.
• You can modify the particular column datatype using MODIFY. You cannot change the name of the column using this statement.

Hope, I explained well in detail.

The solution given by luschn and pillravi works fine unless you receive a Strict-Transport-Security header in the response.

Adding withCredentials: true will solve that issue.

  axios.post(session_url, {
    withCredentials: true,
    headers: {
      "Accept": "application/json",
      "Content-Type": "application/json"
    }
  },{
    auth: {
      username: "USERNAME",
      password: "PASSWORD"
  }}).then(function(response) {
    console.log('Authenticated');
  }).catch(function(error) {
    console.log('Error on Authentication');
  });

VISITOR count should be available under your dashboard > Traffic (or stats or insights):

I believe this occurs when you are trying to checkout a remote branch that your local git repo is not aware of yet. Try:

git remote show origin

If the remote branch you want to checkout is under "New remote branches" and not "Tracked remote branches" then you need to fetch them first:

git remote update
git fetch

Now it should work:

git checkout -b local-name origin/remote-name

The problem is that you are using SingleOrDefault. This method will only succeed when the collections contains exactly 0 or 1 element. I believe you are looking for FirstOrDefault which will succeed no matter how many elements are in the collection.

In my case - In storyboard i had a two labels as in image below, both labels was having desired width values been set before i made it equal. once you unselect, it will change to automatic, and as usual having below things should work like charm.

1.rowHeight = UITableView.automaticDimension, and
2.estimatedRowHeight = 100(In my case).
3.make sure label number of lines is zero.

If you can avoid the need for concurrent writes to a single file, it sounds like you do not need a database to store the chat messages.

Just append the conversation to a text file (1 file per user\conversation). and have a directory/ file structure

Here's a simplified view of the file structure:

chat-1-bob.txt
        201101011029, hi
        201101011030, fine thanks.

chat-1-jen.txt
        201101011030, how are you?
        201101011035, have you spoken to bill recently?

chat-2-bob.txt
        201101021200, hi
        201101021222, about 12:22
chat-2-bill.txt
        201101021201, Hey Bob,
        201101021203, what time do you call this?

You would then only need to store the userid, conversation id (guid ?) & a reference to the file name.

I think you will find it hard to get a more simple scaleable solution.

You can use LOAD_FILE to get the data too see: http://dev.mysql.com/doc/refman/5.0/en/string-functions.html

If you have a requirement to rebuild a conversation you will need to put a value (date time) alongside your sent chat message (in the file) to allow you to merge & sort the files, but at this point it is probably a good idea to consider using a database.

A non-jQuery way to get the available screen dimension. window.screen.width/height has already been put up, but for responsive webdesign and completeness sake I think its worth to mention those attributes:

alert(window.screen.availWidth);
alert(window.screen.availHeight);

http://www.quirksmode.org/dom/w3c_cssom.html#t10 :

availWidth and availHeight - The available width and height on the screen (excluding OS taskbars and such).

Remove Space

I know this is old. I just wanted to dump this here for anyone that was looking for an answer to getting a domain name. This is in coordination with Peter's answer. There "is" a bug as stated by Rich. But, you can always make a simple workaround for that. The way I can tell if they are still on the domain or not is by pinging the domain name. If it responds, continue on with whatever it was that I needed the domain for. If it fails, I drop out and go into "offline" mode. Simple string method.

 string GetDomainName()
    {
        string _domain = IPGlobalProperties.GetIPGlobalProperties().DomainName;

        Ping ping = new Ping();

        try
        {
            PingReply reply = ping.Send(_domain);

            if (reply.Status == IPStatus.Success)
            {
                return _domain;
            }
            else
            {
                return reply.Status.ToString();
            }
        }
        catch (PingException pExp)
        {
            if (pExp.InnerException.ToString() == "No such host is known")
            {
                return "Network not detected!";
            }

            return "Ping Exception";
        }
    }

Just change Product Name in your project's build settings. This will change the bundle identifier with no need to manually touch xcode configuration files.

You can also use sprintf:

char str[1024];
sprintf(str, "somtext %s sometext %s", somevar, somevar);

In our case, the problem was a clone that wrote a .git/config file which contained a url entry that was a read only access method. Changing the url from the :// method to the @ method fixed the problem.

Running git remote -v illuminated the issue some.

Not very hidden, but functions have attributes:

def doNothing():
    pass

doNothing.monkeys = 4
print doNothing.monkeys

I've seen this error a few times now. So often that I wrote a small project, called "Simple" with a Netbeans Maven FXML application template just to go back to as a kind of 'reference model' when things go askew. For testing, I use something like this:

    String sceneFile = "/fxml/main.fxml";
    Parent root = null;
    URL    url  = null;
    try
    {
        url  = getClass().getResource( sceneFile );
        root = FXMLLoader.load( url );
        System.out.println( "  fxmlResource = " + sceneFile );
    }
    catch ( Exception ex )
    {
        System.out.println( "Exception on FXMLLoader.load()" );
        System.out.println( "  * url: " + url );
        System.out.println( "  * " + ex );
        System.out.println( "    ----------------------------------------\n" );
        throw ex;
    }

When you run that snippet and the load fails, you should see a reason, or at least a message from the FXMLLoader. Since it's a test, I throw the exception. You don't want to continue.

Things to note. This is a maven project so the resources will be relative to the resources folder, hence:

• "/fxml/main.fxml".
• The leading slash is required.

• The resource passed to the FXMLLoader is case-sensitive:

  // If you load "main.fxml" and your file is called: "Main.fxml"
  // You will will see the message ...
  
  java.lang.NullPointerException: Location is required.
  

• If you get past that "location is required" issue, then you may have a problem in the FXML

  // Something like this: // javafx.fxml.LoadException: file:/D:/sandbox/javafx/app_examples/person/target/person-00.00.01-SNAPSHOT.jar!/fxml/tableWithDetails.fxml:13

Will mean that there's a problem on Line 13, in the file, per:

• tableWithDetails.fxml :13

In the message. At this point you need to read the FXML and see if you can spot the problem. You could try some of the tips in the related question.

For this problem, my opinion is that the file name was proper case: "Main.fxml". When the file was moved the name was probably changed or the string retyped. Good luck.

If you just want to check string equality, use the == operator. Determining whether two strings are equal is simpler than finding an ordering (which is what compare() gives,) so it might be better performance-wise in your case to use the equality operator.

Longer answer: The API provides a method to check for string equality and a method to check string ordering. You want string equality, so use the equality operator (so that your expectations and those of the library implementors align.) If performance is important then you might like to test both methods and find the fastest.

The approach I use is to start the "Visual Studio Command Prompt" which can be found in the Start menu. E.g. my visual studio 2010 Express install has a shortcute Visual Studio Command Prompt (2010) at Start Menu\Programs\Microsoft Visual Studio 2010\Visual Studio Tools.

This shortcut prepares an environment by calling a script vcvarsall.bat where the compiler, linker, etc. are setup from the right Visual Studio installation.

Alternatively, if you already have a prompt open, you can prepare the environment by calling a similar script:

:: For x86 (using the VS100COMNTOOLS env-var)
call "%VS100COMNTOOLS%"\..\..\VC\bin\vcvars32.bat

or

:: For amd64 (using the full path)
call C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\amd64\vcvars64.bat

However:

Your output (with the '$' prompt) suggests that you are attempting to run CMake from a MSys shell. In that case it might be better to run CMake for MSys or MinGW, by explicitly specifying a makefile generator:

cmake -G"MSYS Makefiles"
cmake -G"MinGW Makefiles"

Run cmake --help to get a list of all possible generators.

In my understanding, the way Android handles the MVC pattern is like:

You have an Activity, which serves as the controller. You have a class which responsibility is to get the data - the model, and then you have the View class which is the view.

When talking about the view most people think only for its visual part defined in the xml. Let's not forget that the View also has a program part with its constructors, methods and etc, defined in the java class.

100 characters.

This is the var (variable) in varchar: you only store what you enter (and an extra 2 bytes to store length upto 65535)

If it was char(200) then you'd always store 200 characters, padded with 100 spaces

See the docs: "The CHAR and VARCHAR Types"

2. install or upgrade openssl package: sudo port install openssl or sudo port upgrade openssl

On Windows you must edit the file daemon.json or windows-daemon-options.json, the default location of the configuration file on Windows is %programdata%\docker\config\daemon.json or %programdata%\docker\resources\windows-daemon-options.json

The optional field features on the json file, allows users to enable or disable specific daemon features. Example: {"features":{"buildkit": true}} enables buildkit as the default docker image builder.

var d = new Date();

var today = d.getFullYear() + '/' + ('0'+(d.getMonth()+1)).slice(-2) + '/' + ('0'+d.getDate()).slice(-2);

Remove numbers, underscore, white-spaces and special characters from the string sentence.

str.replace(/[0-9`~!@#$%^&*()_|+\-=?;:'",.<>\{\}\[\]\\\/]/gi,'');

Demo

Use the @RequestParam to pass a parameter to the controller handler method. In the jsp your form should have an input field with name = "id" like the following:

<input type="text" name="id" />
<input type="submit" />

Then in your controller, your handler method should be like the following:

@RequestMapping("listNotes")
public String listNotes(@RequestParam("id") int id) {
    Person person = personService.getCurrentlyAuthenticatedUser();
    model.addAttribute("person", new Person());
    model.addAttribute("listPersons", this.personService.listPersons());
    model.addAttribute("listNotes", this.notesService.listNotesBySectionId(id, person));
    return "note";
}

For me, it is not about a "common aggregation problem", but just about an incorrect SQL query. The single correct answer for "select the maximum avg for each cname..." is

SELECT cname, MAX(avg) FROM makerar GROUP BY cname;

The result will be:

 cname  |      MAX(avg)
--------+---------------------
 canada | 2.0000000000000000
 spain  | 5.0000000000000000

This result in general answers the question "What is the best result for each group?". We see that the best result for spain is 5 and for canada the best result is 2. It is true, and there is no error. If we need to display wmname also, we have to answer the question: "What is the RULE to choose wmname from resulting set?" Let's change the input data a bit to clarify the mistake:

  cname | wmname |        avg           
--------+--------+-----------------------
 spain  | zoro   |  1.0000000000000000
 spain  | luffy  |  5.0000000000000000
 spain  | usopp  |  5.0000000000000000

Which result do you expect on runnig this query: SELECT cname, wmname, MAX(avg) FROM makerar GROUP BY cname;? Should it be spain+luffy or spain+usopp? Why? It is not determined in the query how to choose "better" wmname if several are suitable, so the result is also not determined. That's why SQL interpreter returns an error - the query is not correct.

In the other word, there is no correct answer to the question "Who is the best in spain group?". Luffy is not better than usopp, because usopp has the same "score".

Here is a simple Windows bat file to split incoming file into 50 parts. Each part has length 1 minute. Sorry for such dumb script. I hope it is better to have a dumb windows script instead of do not have it at all. Perhaps it help someone. (Based on "bat file for loop" from this site.)

You can create an empty array by specifying the Element type of your array in the declaration.

For example:

// Shortened forms are preferred
var emptyDoubles: [Double] = []

// The full type name is also allowed
var emptyFloats: Array<Float> = Array()

solution one: Change the version of apache tomcat (latest one is preferred) (manual process).

solution two: Install latest eclipse IDE and configure the apache tomcat server (internally automatic process i,e eclipse handles the configuration part).

After successful procedure of automatic process, manual process shall be working good.

Run multiple sleeps and commands

sleep 5 && cd /var/www/html && git pull && sleep 3 && cd ..

This will wait for 5 seconds before executing the first script, then will sleep again for 3 seconds before it changes directory again.

It's not ideal, but you could disable Jackson's auto-discovery of JSON properties, using @JsonAutoDetect at the class level. This would prevent it from trying to handle the Javassist stuff (and failing).

This means that you then have to annotate each getter manually (with @JsonProperty), but that's not necessarily a bad thing, since it keeps things explicit.

<textarea style="resize:none" name="name" cols="num" rows="num"></textarea>

Just an example

In Python:

• Instance methods: require the self argument.
• Class methods: take the class as a first argument.
• Static methods: do not require either the instance (self) or the class (cls) argument.

__init__ is a special function and without overriding __new__ it will always be given the instance of the class as its first argument.

An example using the builtin classmethod and staticmethod decorators:

import sys

class Num:
    max = sys.maxint

    def __init__(self,num):
        self.n = num

    def getn(self):
        return self.n

    @staticmethod
    def getone():
        return 1

    @classmethod
    def getmax(cls):
        return cls.max

myObj = Num(3)
# with the appropriate decorator these should work fine
myObj.getone()
myObj.getmax()
myObj.getn()

That said, I would try to use @classmethod/@staticmethod sparingly. If you find yourself creating objects that consist of nothing but staticmethods the more pythonic thing to do would be to create a new module of related functions.

In my python interpreter exit is actually a string and not a function -- 'Use Ctrl-D (i.e. EOF) to exit.'. You can check on your interpreter by entering type(exit)

In active python what is happening is that exit is a function. If you do not call the function it will print out the string representation of the object. This is the default behaviour for any object returned. It's just that the designers thought people might try to type exit to exit the interpreter, so they made the string representation of the exit function a helpful message. You can check this behaviour by typing str(exit) or even print exit.

if($(this).attr("name"))

There's no hasAttr but hitting an attribute by name will just return undefined if it doesn't exist.

This is why the below works. If you remove the name attribute from #heading the second alert will fire.

Update: As per the comments, the below will ONLY work if the attribute is present AND is set to something not if the attribute is there but empty

<script type="text/javascript">
$(document).ready(function()
{
    if ($("#heading").attr("name"))
      alert('Look, this is showing because it\'s not undefined');
    else
      alert('This would be called if it were undefined or is there but empty');
});
</script>

There is a program "OpenFiles", seems to be part of windows 7. Seems that it can do what you want. It can list files opened by remote users (through file share) and, after calling "openfiles /Local on" and a system restart, it should be able to show files opened locally. The latter is said to have performance penalties.
