Regarding the question 'can R help me find the best fitting model', there is probably a function to do this, assuming you can state the set of models to test, but this would be a good first approach for the set of n-1 degree polynomials:

polyfit <- function(i) x <- AIC(lm(y~poly(x,i)))
as.integer(optimize(polyfit,interval = c(1,length(x)-1))$minimum)

Notes

• The validity of this approach will depend on your objectives, the assumptions of optimize() and AIC() and if AIC is the criterion that you want to use,

• polyfit() may not have a single minimum. check this with something like:

  for (i in 2:length(x)-1) print(polyfit(i))
  

• I used the as.integer() function because it is not clear to me how I would interpret a non-integer polynomial.

• for testing an arbitrary set of mathematical equations, consider the 'Eureqa' program reviewed by Andrew Gelman here

Update

Also see the stepAIC function (in the MASS package) to automate model selection.

In my case the nullable variables/elements were all String type. So, I simply performed a check and assigned them string.Empty in case of NULL. This way I got rid of the unnecessary nil and xmlns attributes (p3:nil="true" xmlns:p3="http://www.w3.org/2001/XMLSchema-instance)

// Example:

myNullableStringElement = varCarryingValue ?? string.Empty

// OR

myNullableStringElement = myNullableStringElement ?? string.Empty

This function isn't just for headers. You can do a lot of interesting stuff with this. Example: You could split your page into sections and use it like this:

$someTemplate->selectSection('header');
echo 'This is the header.';

$someTemplate->selectSection('content');
echo 'This is some content.';

You can capture the output that is generated here and add it at two totally different places in your layout.

Worth noting that the code you see is sent to the database as is, the queries are sent separately to prevent SQL injection. AFAIK The ? marks are placeholders that are replaced by the number params by the database, not by hibernate.

I just wrote this and it looks more clean to me:

const fs = require('fs');
const util = require('util');

const readdir = util.promisify(fs.readdir);
const readFile = util.promisify(fs.readFile);

const readFiles = async dirname => {
    try {
        const filenames = await readdir(dirname);
        console.log({ filenames });
        const files_promise = filenames.map(filename => {
            return readFile(dirname + filename, 'utf-8');
        });
        const response = await Promise.all(files_promise);
        //console.log({ response })
        //return response
        return filenames.reduce((accumlater, filename, currentIndex) => {
            const content = response[currentIndex];
            accumlater[filename] = {
                content,
            };
            return accumlater;
        }, {});
    } catch (error) {
        console.error(error);
    }
};

const main = async () => {

    const response = await readFiles(
        './folder-name',
    );
    console.log({ response });
};

You can modify the response format according to your need. The response format from this code will look like:

{
   "filename-01":{
      "content":"This is the sample content of the file"
   },
   "filename-02":{
      "content":"This is the sample content of the file"
   }
}

char arr[50];
gets(arr);
int c=0,i,l;
l=strlen(arr);

    for(i=0;i<l;i++){
        if(arr[i]==32){
            printf("\n");
        }
        else
        printf("%c",arr[i]);
    }

An Alternative Solution to the above

Card(
  shape: RoundedRectangleBorder(
     borderRadius: BorderRadius.only(topLeft: Radius.circular(20), topRight: Radius.circular(20))),
  color: Colors.white,
  child: ...
)

You can use BorderRadius.only() to customize the corners you wish to manage.

Branches are made of wood and grow from the trunk of the tree. Tags are made of paper (derivative of wood) and hang like Christmas Ornaments from various places in the tree.

Your project is the tree, and your feature that will be added to the project will grow on a branch. The answer is branch.

If you write HTML into javascript anywhere, it will think the HTML is written in javascript. The best way to include HTML in JavaScript is to write the HTML code on the page. The browser can't display HTML tags, so the browser will recognize the HTML and write this code in HTML.

document.write("<p>Hello World!</p>");

Though if you would like to write HTML on a function, GetElementById is the best:

function functionName() {
   document.getElementById(" the id of the HTML element to be written in ").innerHTML = "whatever you want to say"
}

Hope this helps!

Another easy way is to use the WC_Product_Factory class and then call function get_product(ID)

http://docs.woothemes.com/wc-apidocs/source-class-WC_Product_Factory.html#16-63

sample:

// assuming the list of product IDs is are stored in an array called IDs;
$_pf = new WC_Product_Factory();  
foreach ($IDs as $id) {

    $_product = $_pf->get_product($id);

    // from here $_product will be a fully functional WC Product object, 
    // you can use all functions as listed in their api
}

You can then use all the function calls as listed in their api: http://docs.woothemes.com/wc-apidocs/class-WC_Product.html

A character in Java is a Unicode code-unit which is treated as an unsigned number. So if you perform c = (char)b the value you get is 2^16 - 56 or 65536 - 56.

Or more precisely, the byte is first converted to a signed integer with the value 0xFFFFFFC8 using sign extension in a widening conversion. This in turn is then narrowed down to 0xFFC8 when casting to a char, which translates to the positive number 65480.

From the language specification:

5.1.4. Widening and Narrowing Primitive Conversion

First, the byte is converted to an int via widening primitive conversion (§5.1.2), and then the resulting int is converted to a char by narrowing primitive conversion (§5.1.3).

To get the right point use char c = (char) (b & 0xFF) which first converts the byte value of b to the positive integer 200 by using a mask, zeroing the top 24 bits after conversion: 0xFFFFFFC8 becomes 0x000000C8 or the positive number 200 in decimals.

Above is a direct explanation of what happens during conversion between the byte, int and char primitive types.

If you want to encode/decode characters from bytes, use Charset, CharsetEncoder, CharsetDecoder or one of the convenience methods such as new String(byte[] bytes, Charset charset) or String#toBytes(Charset charset). You can get the character set (such as UTF-8 or Windows-1252) from StandardCharsets.

Or you can use JQuery - just add your input field to the class "phone" and put this in your script section:

$(".phone").keyup(function () {
        $(this).val($(this).val().replace(/^(\d{3})(\d{3})(\d)+$/, "($1)$2-$3"));

There is no error message but you can see that the phone number is not correctly formatted until you have entered all ten digits.

If you can use bootstrap3 then you can use css "navbar-fixed-top" also you need to add below css to push your page content down

body{

   margin-top:100px;
}

With CSS 2 you can do this:

input[type='checkbox'] { ... }

This should be pretty widely supported by now. See support for browsers

If you are using Ubuntu 14.04 ffmpeg is not available. You can install it by using the instructions directly from https://www.ffmpeg.org/download.html.

In short you will have to:

sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install ffmpeg gstreamer0.10-ffmpeg

If this does not work maybe try using sudo apt-get dist-upgrade but this may broke things in your system.

try:

%matplotlib notebook

see jakevdp reply here

EDIT for JupyterLab users:

Follow the instructions to install jupyter-matplotlib

Then the magic command above is no longer needed, as in the example:

# Enabling the `widget` backend.
# This requires jupyter-matplotlib a.k.a. ipympl.
# ipympl can be install via pip or conda.
%matplotlib widget
# aka import ipympl

import matplotlib.pyplot as plt

plt.plot([0, 1, 2, 2])
plt.show()

Finally, note Maarten Breddels' reply; IMHO ipyvolume is indeed very impressive (and useful!).

You can also use this approach in case you want to pass some http parameters and send a json request:

(note: I have added in some extra code just incase it helps any other future readers)

public void postJsonWithHttpParams() throws URISyntaxException, UnsupportedEncodingException, IOException {

    //add the http parameters you wish to pass
    List<NameValuePair> postParameters = new ArrayList<>();
    postParameters.add(new BasicNameValuePair("param1", "param1_value"));
    postParameters.add(new BasicNameValuePair("param2", "param2_value"));

    //Build the server URI together with the parameters you wish to pass
    URIBuilder uriBuilder = new URIBuilder("http://google.ug");
    uriBuilder.addParameters(postParameters);

    HttpPost postRequest = new HttpPost(uriBuilder.build());
    postRequest.setHeader("Content-Type", "application/json");

    //this is your JSON string you are sending as a request
    String yourJsonString = "{\"str1\":\"a value\",\"str2\":\"another value\"} ";

    //pass the json string request in the entity
    HttpEntity entity = new ByteArrayEntity(yourJsonString.getBytes("UTF-8"));
    postRequest.setEntity(entity);

    //create a socketfactory in order to use an http connection manager
    PlainConnectionSocketFactory plainSocketFactory = PlainConnectionSocketFactory.getSocketFactory();
    Registry<ConnectionSocketFactory> connSocketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
            .register("http", plainSocketFactory)
            .build();

    PoolingHttpClientConnectionManager connManager = new PoolingHttpClientConnectionManager(connSocketFactoryRegistry);

    connManager.setMaxTotal(20);
    connManager.setDefaultMaxPerRoute(20);

    RequestConfig defaultRequestConfig = RequestConfig.custom()
            .setSocketTimeout(HttpClientPool.connTimeout)
            .setConnectTimeout(HttpClientPool.connTimeout)
            .setConnectionRequestTimeout(HttpClientPool.readTimeout)
            .build();

    // Build the http client.
    CloseableHttpClient httpclient = HttpClients.custom()
            .setConnectionManager(connManager)
            .setDefaultRequestConfig(defaultRequestConfig)
            .build();

    CloseableHttpResponse response = httpclient.execute(postRequest);

    //Read the response
    String responseString = "";

    int statusCode = response.getStatusLine().getStatusCode();
    String message = response.getStatusLine().getReasonPhrase();

    HttpEntity responseHttpEntity = response.getEntity();

    InputStream content = responseHttpEntity.getContent();

    BufferedReader buffer = new BufferedReader(new InputStreamReader(content));
    String line;

    while ((line = buffer.readLine()) != null) {
        responseString += line;
    }

    //release all resources held by the responseHttpEntity
    EntityUtils.consume(responseHttpEntity);

    //close the stream
    response.close();

    // Close the connection manager.
    connManager.close();
}

Specify the ax argument to matplotlib.pyplot.colorbar(), e.g.

import numpy as np
import matplotlib.pyplot as plt

fig, ax = plt.subplots(2, 2)
for i in range(2):
    for j in range(2):
         data = np.array([[i, j], [i+0.5, j+0.5]])
         im = ax[i, j].imshow(data)
         plt.colorbar(im, ax=ax[i, j])

plt.show()

IF you want to install Maven in Eclipse(Java EE) Indigo Then follow these Steps :

1. Eclipse -> Help -> Install New Software.

2. Type " http://download.eclipse.org/releases/indigo/ " & Hit Enter.

3. Expand " Collaboration " tag.

4. Select Maven plugin from there.

5. Click on next .

6. Accept the agreement & click finish.

After installing the maven it will ask for restarting the Eclipse,So restart the eclipse again to see the changes.

The easiest way to get rid of this is to:

1. Dont use document.open().
2. Instead use this.document.location.href = location; where location is the url to be loaded

Ex :

<script>
function loadUrl(location)
{
this.document.location.href = location;
}</script>

<div onclick="loadUrl('company_page.jsp')">Abc</div>

This worked very well for me. Cheers

In my case, a script was running command while redirecting both stdout and stderr to a file, something like:

cmd > log 2>&1

I needed to update it such that when there is a failure, take some actions based on the error messages. I could of course remove the dup 2>&1 and capture the stderr from the script, but then the error messages won't go into the log file for reference. While the accepted answer from @lhunath is supposed to do the same, it redirects stdout and stderr to different files, which is not what I want, but it helped me to come up with the exact solution that I need:

(cmd 2> >(tee /dev/stderr)) > log

With the above, log will have a copy of both stdout and stderr and I can capture stderr from my script without having to worry about stdout.

I know this post is closed but I think my way could help some people. So there it is :

My dataset is very similar but is a bit more complex. It has numbers, alphanumeric data :

1
2
Chair 
3
0
4
5
-
Table
10
13
19
Windows
99
102
Dog

I would like to have the '-' symbol at first, then the numbers, then the text.

So I go like this :

SELECT name, (name = '-') boolDash, (name = '0') boolZero, (name+0 > 0) boolNum 
FROM table 
ORDER BY boolDash DESC, boolZero DESC, boolNum DESC, (name+0), name

The result should be something :

-
0    
1
2
3
4
5
10
13
99
102
Chair
Dog
Table
Windows

The whole idea is doing some simple check into the SELECT and sorting with the result.

You can search "slashdot effect analysis" for graphs of what you would see if some aspect of the site suddenly became popular in the news, e.g. this graph on wiki.

Web-applications that survive tend to be the ones which can generate static pages instead of putting every request through a processing language.

There was an excellent video (I think it might have been on ted.com? I think it might have been by flickr web team? Does someone know the link?) with ideas on how to scale websites beyond the single server, e.g. how to allocate connections amongst the mix of read-only and read-write servers to get best effect for various types of users.

Every answer here is so complicated...

What about this to "stash":

git diff /dir/to/file/file_to_stash > /tmp/stash.patch
git checkout -- /dir/to/file/file_to_stash

This to pop the file change back:

git apply /tmp/stash.patch

Exact same behavior as stashing one file and popping it back in.

You had a unescaped " in the onclick handler, escape it with \"

$('#contentData').append("<div class='media'><div class='media-body'><h4 class='media-heading'>" + v.Name + "</h4><p>" + v.Description + "</p><a class='btn' href='" + type + "'  onclick=\"(canLaunch('" + v.LibraryItemId + " '))\">View &raquo;</a></div></div>")

To avoid this warning, do not use:

async: false

in any of your $.ajax() calls. This is the only feature of XMLHttpRequest that's deprecated.

The default is async: true, so if you never use this option at all, your code should be safe if the feature is ever really removed.

However, it probably won't be -- it may be removed from the standards, but I'll bet browsers will continue to support it for many years. So if you really need synchronous AJAX for some reason, you can use async: false and just ignore the warnings. But there are good reasons why synchronous AJAX is considered poor style, so you should probably try to find a way to avoid it. And the people who wrote Flash applications probably never thought it would go away, either, but it's in the process of being phased out now.

Notice that the Fetch API that's replacing XMLHttpRequest does not even offer a synchronous option.

It uses the slice method arrays have and calls it with its this being the arguments object. This means it calls it as if you did arguments.slice() assuming arguments had such a method.

Creating a slice without any arguments will simply take all elements - so it simply copies the elements from arguments to an array.

This is not an example use or an explanation of how to use FLAG_ACTIVITY_NO_ANIMATION, however it does answer how to disable the Activity switching animation, as asked in the question title:

I can close it with:

adb shell reboot -p

needs name of string and its length will zero all characters other methods might stop at the first zero they encounter

    void strClear(char p[],u8 len){u8 i=0; 
        if(len){while(i<len){p[i]=0;i++;}}

I had a very similar problem with davfs. In the man page of umount.davfs, I found that the -f -l -n -r -v options are ignored by umount.davfs. To force-unmount my davfs mount, I had to use umount -i -f -l /media/davmount.

You may come across this message/error, after installing epel-release. The quick fix is to update your SSL certificates:

yum -y upgrade ca-certificates

Chances are the above error may also occur while certificate update, if so, just disable the epel repo i.e. use the following command:

yum -y upgrade ca-certificates --disablerepo=epel 

Once the certificates will be updated, you'll be able to use yum normally, even the epel repo will work fine. In case you're getting this same error for a different repo, just put it's name against the --disablerepo=<repo-name> flag.

Note: use sudo if you're not the root user.

There are two ways that you can achieve this. Concatenation, and shift/rotate functions.

• Concatenation is the "manual" way of doing things. You specify what part of the original signal that you want to "keep" and then concatenate on data to one end or the other. For example: tmp <= tmp(14 downto 0) & '0';

• Shift functions (logical, arithmetic): These are generic functions that allow you to shift or rotate a vector in many ways. The functions are: sll (shift left logical), srl (shift right logical). A logical shift inserts zeros. Arithmetric shifts (sra/sla) insert the left most or right most bit, but work in the same way as logical shift. Note that for all of these operations you specify what you want to shift (tmp), and how many times you want to perform the shift (n bits)

• Rotate functions: rol (rotate left), ror (rotate right). Rotating does just that, the MSB ends up in the LSB and everything shifts left (rol) or the other way around for ror.

Here is a handy reference I found (see the first page).

byte[] b = IOUtils.toByteArray((new URL( )).openStream()); //idiom

Note however, that stream is not closed in the above example.

if you want a (76-character) chunk (using commons codec)...

byte[] b = Base64.encodeBase64(IOUtils.toByteArray((new URL( )).openStream()), true);

'pywin32' is its canonical name.

When working with buckets that have 1000+ objects its necessary to implement a solution that uses the NextContinuationToken on sequential sets of, at most, 1000 keys. This solution first compiles a list of objects then iteratively creates the specified directories and downloads the existing objects.

import boto3
import os

s3_client = boto3.client('s3')

def download_dir(prefix, local, bucket, client=s3_client):
    """
    params:
    - prefix: pattern to match in s3
    - local: local path to folder in which to place files

    """
    keys = []
    dirs = []
    next_token = ''
    base_kwargs = {
        'Bucket':bucket,
        'Prefix':prefix,
    }
    while next_token is not None:
        kwargs = base_kwargs.copy()
        if next_token != '':
            kwargs.update({'ContinuationToken': next_token})
        results = client.list_objects_v2(**kwargs)
        contents = results.get('Contents')
        for i in contents:
            k = i.get('Key')

Actually the answer by ƒernando Valle doesn't seem to be correct. Then again, your question is overly vague because you fail to mention what is wrong or isn't working.

Looking at your code I am assuming the Notification simply isn't showing.

Your notification is not showing, because you didn't provide an icon. Even though the SDK documentation doesn't mention it being required, it is in fact very much so and your Notification will not show without one.

addAction is only available since 4.1. Prior to that you would use the PendingIntent to launch an Activity. You seem to specify a PendingIntent, so your problem lies elsewhere. Logically, one must conclude it's the missing icon.

For me was a declaration incomplete. For example:

var isInverted: Bool

Instead the correct way:

var isInverted: Bool = false

@prateek thank you for your help. I rewrote the function with comments for use in a program. Increase 8 for more bits (up to 32 for an integer).

std::vector <bool> bits_from_int (int integer)    // discern which bits of PLC codes are true
{
    std::vector <bool> bool_bits;

    // continously divide the integer by 2, if there is no remainder, the bit is 1, else it's 0
    for (int i = 0; i < 8; i++)
    {
        bool_bits.push_back (integer%2);    // remainder of dividing by 2
        integer /= 2;    // integer equals itself divided by 2
    }

    return bool_bits;
}

It is a unicode char \u003C = <

Please have a look at http://jsfiddle.net/2dJAN/59/

$("#submit").click(function () {
var url = $(location).attr('href');
$('#spn_url').html('<strong>' + url + '</strong>');
});

Or even more simple if you don't want to use a lot of linq and for some reason don't want to use a for loop.

int i = 0;
foreach(var x in arr)
{
   //Do some stuff
   i++;
}

First of all go to the /home directorty then open invisible shell script with some text editor, ~/.bash_profile (macOS) or ~/.bashrc (linux) go to the bottom, you would see something like this,

export LD_LIBRARY_PATH = /usr/local/lib

change this like that( remove blank point around the = ),

export LD_LIBRARY_PATH=/usr/local/lib

it should be useful.

To execute a python script in a bash script you need to call the same command that you would within a terminal. For instance

> python python_script.py var1 var2

To access these variables within python you will need

import sys
print sys.argv[0] # prints python_script.py
print sys.argv[1] # prints var1
print sys.argv[2] # prints var2

If you are in a web application which already uses Spring and if you do not want to include Apache Commons IO for simple file copying, you can use FileCopyUtils of the Spring framework.

Safe navigation operator or Existential Operator or Null Propagation Operator is supported in Angular Template. Suppose you have Component class

  myObj:any = {
    doSomething: function () { console.log('doing something'); return 'doing something'; },
  };
  myArray:any;
  constructor() { }

  ngOnInit() {
    this.myArray = [this.myObj];
  }

You can use it in template html file as following:

<div>test-1: {{  myObj?.doSomething()}}</div>
<div>test-2: {{  myArray[0].doSomething()}}</div>
<div>test-3: {{  myArray[2]?.doSomething()}}</div>

Starting from Spring Boot version 1.2.0.RELEASE , there is a property you can add to your application.properties to set a default date format to all of your classes spring.jackson.date-format.

For your date format example, you would add this line to your properties file:

spring.jackson.date-format=yyyy-MM-dd

It's as the error message says "The value violated the integrity constraints for the column" for column "Copy of F2"

Make it so it doesn't violate the value in the target table. What the allowable values are, data types, etc are not provided in your question so we cannot be more specific in answering.

To address the downvote, No, really it's as it says: you are putting something into a column that is not allowed. It could be Faizan points out, that you're putting a NULL into a NOT NULLable column, but it could be a whole host of other things and as the original poster never provided any update, we're left to guess. Was there a foreign key constraint that the insert violated? Maybe there's a check constraint that got blown? Maybe the source column in Excel has a valid date value for Excel that is not valid for the target column's date/time data type.

Thus, baring concrete information, the best possible answer is "don't do the thing that breaks it" In this case, something about "Copy of F2" is bad for the target column. Give us table definitions, supplied values, etc, then you can specific answers.

Telling people to make a NOT NULLable column into a NULLable one might be the right answer. It might also be the most horrific answer known to mankind. If an existing process expects there to always be a value in column "Copy of F2" changing the constraint to NULL can wreak havoc on existing queries. For example

SELECT * FROM ArbitraryTable AS T WHERE T.[Copy of F2] = '';

Currently, that query retrieves everything that was freshly imported because Copy of F2 is a poorly named status indicator. That data needs to get fed into the next system so... bills can get paid. As soon as you make it such that unprocessed rows can have a NULL value, the above query no longer satisfies that. Bills don't get paid, collections repos your building and now you're out of a job, all because you didn't do impact analysis, etc, etc.

In general, this is a really bad way of doing things due to multipath interference. This is definitely more of an RF engineering question than a coding one.

Tl;dr, the wifi RF energy gets scattered in different directions after bouncing off walls, people, the floor etc. There's no way of telling where you are by trianglation alone, unless you're in an empty room with the wifi beacons placed in exactly the right place.

Google is able to get away with this because they essentially can map where every wifi SSID is to a GPS location when any android user (who opts in to their service) walks into range. That way, the next time a user walks by there, even without a perfect GPS signal, the google mothership can tell where you are. Typically, they'll use that in conjunction with a crappy GPS signal.

What I have seen done is a grid of Zigbee or BTLE devices. If you know where these are laid out, you can used the combined RSS to figure out relatively which ones you're closest to, and go from there.

Not sure if this is the fastest way, but this is something I stumbled upon (long time ago in high-school) when I was bored and playing with my calculator during math class. At that time, I was really amazed this was working...

public static boolean isIntRoot(int number) {
    return isIntRootHelper(number, 1);
}

private static boolean isIntRootHelper(int number, int index) {
    if (number == index) {
        return true;
    }
    if (number < index) {
        return false;
    }
    else {
        return isIntRootHelper(number - 2 * index, index + 1);
    }
}

We used jquery trigger to onload have a script hit the button for us

$(".class_name").trigger('click');

If you install MySQL via homebrew on MacOS, you might need to delete your old data directory /usr/local/var/mysql. Otherwise, it will fail during the initialization process with the following error:

The reason for "permission denied" is because your Android machine has not been correctly rooted. Did you see $ after you started adb shell? If you correctly rooted your machine, you would have seen # instead.

If you see the $, try entering Super User mode by typing su. If Root is enabled, you will see the # - without asking for password.

Starting with TypeScript 2.2 using dot notation to access indexed properties is allowed. You won't get error TS2339 on your example.

See Dotted property for types with string index signatures in TypeScript 2.2 release note.

If you are utilizing underscore, you can use this nice short one-liner:

_.indexOf(arr, _.max(arr))

It will first find the value of the largest item in the array, in this case 22. Then it will return the index of where 22 is within the array, in this case 2.

you may try the TO_CHAR function to convert the result

e.g.

SELECT TO_CHAR(92, '99.99') AS RES FROM DUAL

SELECT TO_CHAR(92.258, '99.99') AS RES FROM DUAL

Hope it helps

I am using the code formatter of the IDE I use. That might differ, but it can be setup in the Preferences/Options.

I like this one:

if (statement)
{
    // comment to denote in words the case
    do this;
    // keep this block simple, if more than 10-15 lines needed, I add a function for it
}
else
{
    do this;
}

Adding Path Variables to OS X Lion

This was pretty straight forward and worked for me, in terminal:

$echo "export PATH=$PATH:/path/to/whatever" >> .bash_profile #replace "/path/to/whatever" with the location of what you want to add to your bash profile, i.e: $ echo "export PATH=$PATH:/usr/local/Cellar/nginx/1.0.12/sbin" >> .bash_profile 
$. .bash_profile #restart your bash shell

The correct answer is to create an orphan branch. I explain how to do this in detail on my blog._{(Archived link)}

...

Before starting, upgrade to the latest version of GIT. To make sure you’re running the latest version, run

which git

If it spits out an old version, you may need to augment your PATH with the folder containing the version you just installed.

Ok, we’re ready. After doing a cd into the folder containing your git checkout, create an orphan branch. For this example, I’ll name the branch “mybranch”.

git checkout --orphan mybranch

Delete everything in the orphan branch

git rm -rf .

Make some changes

vi README.txt

Add and commit the changes

git add README.txt
git commit -m "Adding readme file"

That’s it. If you run

git log

you’ll notice that the commit history starts from scratch. To switch back to your master branch, just run

git checkout master

You can return to the orphan branch by running

git checkout mybranch

If you don't use conda, just use :

pip install openpyxl

If you use conda, I'd recommend :

conda install -c anaconda openpyxl

instead of simply conda install openpyxl

Because there are issues right now with conda updating (see GitHub Issue #8842) ; this is being fixed and it should work again after the next release (conda 4.7.6)

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

In addition to checking your table setup to confirm that the field is set to NOT NULL with a default of CURRENT_TIMESTAMP, you can insert date/time values from PHP by writing them in a string format compatible with MySQL.

 $timestamp = date("Y-m-d H:i:s");

This will give you the current date and time in a string format that you can insert into MySQL.

    //exit();
    $count++;                                      // add this line

    if($count>1){                                  // add this line
      $sql = "INSERT into prod_list_1(p_bench,p_name,p_price,p_reason) values ('$emapData[0]','$emapData[1]','$emapData[2]','$emapData[3]')";
      mysql_query($sql);
    }                                              // add this line

Try this, it should solve your issue

1. In your config.php, add www pre in your domain.com. For example:

   HTTP define('HTTP_SERVER', 'http://domain name with www/');
   HTTPS define('HTTPS_SERVER', 'http://domain name with www/');
   

2. Add this to your .htaccess file

   RewriteCond %{REQUEST_METHOD} OPTIONS RewriteRule ^(.*)$ $1 [R=200,L]
   

I also enable the 'u' option on every bash script I write in order to do some extra checking:

set -u 

This will report the usage of uninitialized variables, like in the following script 'check_init.sh'

#!/bin/sh
set -u
message=hello
echo $mesage

Running the script :

$ check_init.sh

Will report the following :

./check_init.sh[4]: mesage: Parameter not set.

Very useful to catch typos

In some ways, your question seems very legitimate, but I still might label it an XY problem. I'm guessing the end result is that you want to display the sorted values in some way? As Bergi said in the comments, you can never quite rely on Javascript objects ( {i_am: "an_object"} ) to show their properties in any particular order.

For the displaying order, I might suggest you take each key of the object (ie, i_am) and sort them into an ordered array. Then, use that array when retrieving elements of your object to display. Pseudocode:

var keys = [...]
var sortedKeys = [...]
for (var i = 0; i < sortedKeys.length; i++) {
  var key = sortedKeys[i];
  addObjectToTable(json[key]);
}

I have now tried your suggestions and found that it kinda works,

1. The dialog div is alsways written out in plaintext
2. With the $.post version it actually works in terms that the controller gets called and actually cancels the booking, but the dialog stays open and page doesn't refresh. With the get version window.location = h.ref works great.

Se my "new" script below:

$('a.cancel').click(function() {
        var a = this;               
        $("#dialog").dialog({
            autoOpen: false,
            buttons: {
                "Ja": function() {
                    $.post(a.href);                     
                },
                "Nej": function() { $(this).dialog("close"); }
            },
            modal: true,
            overlay: {
                opacity: 0.5,

            background: "black"
        }
    });
    $("#dialog").dialog('open');
    return false;
});

});

Any clues?

oh and my Action link now looks like this:

<%= Html.ActionLink("Cancel", "Cancel", new { id = v.BookingId }, new  { @class = "cancel" })%>

You'll need to couple the event listener to $rootScope in Angular 1.x, but you should probably future proof your code a bit by not storing the value of the previous location on $rootScope. A better place to store the value would be a service:

var app = angular.module('myApp', [])
.service('locationHistoryService', function(){
    return {
        previousLocation: null,

        store: function(location){
            this.previousLocation = location;
        },

        get: function(){
            return this.previousLocation;
        }
})
.run(['$rootScope', 'locationHistoryService', function($location, locationHistoryService){
    $rootScope.$on('$locationChangeSuccess', function(e, newLocation, oldLocation){
        locationHistoryService.store(oldLocation);
    });
}]);

Either two different IP addresses (like recommended) or one web server is reverse-proxying the other (which is listening on a port <>80).

For instance: Apache listens on port 80, IIS on port 8080. Every http request goes to Apache first (of course). You can then decide to forward every request to a particular (named virtual) domain or every request that contains a particular directory (e.g. http://www.example.com/winapp/) to the IIS.

Advantage of this concept is that you have only one server listening to the public instead of two, you are more flexible as with two distinct servers.

Drawbacks: some webapps are crappily designed and a real pain in the ass to integrate into a reverse-proxy infrastructure. A working IIS webapp is dependent on a working Apache, so we have some inter-dependencies.

String is a special class in Java. It is Thread Safe which means "Once a String instance is created, the content of the String instance will never changed ".

Here is what is going on for

 zText += "foo";

First, Java compiler will get the value of zText String instance, then create a new String instance whose value is zText appending "foo". So you know why the instance that zText point to does not changed. It is totally a new instance. In fact, even String "foo" is a new String instance. So, for this statement, Java will create two String instance, one is "foo", another is the value of zText append "foo". The rule is simple: The value of String instance will never be changed.

For method fillString, you can use a StringBuffer as parameter, or you can change it like this:

String fillString(String zText) {
    return zText += "foo";
}

Proper Swift 3.0 for iOS 10+ solution: Using ImageRenderer and closure syntax:

func imageWith(newSize: CGSize) -> UIImage {
    let renderer = UIGraphicsImageRenderer(size: newSize)
    let image = renderer.image { _ in
        self.draw(in: CGRect.init(origin: CGPoint.zero, size: newSize))
    }

    return image.withRenderingMode(self.renderingMode)
}

And here's the Objective-C version:

@implementation UIImage (ResizeCategory)
- (UIImage *)imageWithSize:(CGSize)newSize
{
    UIGraphicsImageRenderer *renderer = [[UIGraphicsImageRenderer alloc] initWithSize:newSize];
    UIImage *image = [renderer imageWithActions:^(UIGraphicsImageRendererContext*_Nonnull myContext) {
        [self drawInRect:(CGRect) {.origin = CGPointZero, .size = newSize}];
    }];
    return [image imageWithRenderingMode:self.renderingMode];
}
@end

or

   /etc/init.d/mongodb status     # for MongoDB version < 2.6

   /etc/init.d/mongod status      # for MongoDB version >= 2.6

or

   service mongod status

to see if mongod is running (you need to be root to do this, or prefix everything with sudo). Please note that the 'grep' command will always also show up as a separate process.

Facebook uses what's called the Open Graph Protocol to decide what things to display when you share a link. The OGP looks at your page and tries to decide what content to show. We can lend a hand and actually tell Facebook what to take from our page.

The way we do that is with og:meta tags.

The tags look something like this -

  <meta property="og:title" content="Stuffed Cookies" />
  <meta property="og:image" content="http://fbwerks.com:8000/zhen/cookie.jpg" />
  <meta property="og:description" content="The Turducken of Cookies" />
  <meta property="og:url" content="http://fbwerks.com:8000/zhen/cookie.html">

You'll need to place these or similar meta tags in the <head> of your HTML file. Don't forget to substitute the values for your own!

For more information you can read all about how Facebook uses these meta tags in their documentation. Here is one of the tutorials from there - https://developers.facebook.com/docs/opengraph/tutorial/

Facebook gives us a great little tool to help us when dealing with these meta tags - you can use the Debugger to see how Facebook sees your URL, and it'll even tell you if there are problems with it.

One thing to note here is that every time you make a change to the meta tags, you'll need to feed the URL through the Debugger again so that Facebook will clear all the data that is cached on their servers about your URL.

My approach to the problem is similar to the way datayeah did it. I had a lot of hardcoded width and height values and the app looked fine on a specific device. So I got the screen height of the device and just created a factor to scale the hardcoded values.

double heightFactor = MediaQuery.of(context).size.height/708

where 708 is the height of the specific device.

Here is my solution:

<!-- jquery smooth scroll to id's -->   
<script>
$(function() {
  $('a[href*=\\#]:not([href=\\#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 500);
        return false;
      }
    }
  });
});
</script>

With just this snippet you can use an unlimited number of hash-links and corresponding ids without having to execute a new script for each.

I already explained how it works in another thread here: https://stackoverflow.com/a/28631803/4566435 (or here's a direct link to my blog post)

For clarifications, let me know. Hope it helps!

Something like this should remove it

document.getElementById('x').style.visibility='hidden';

If you are going to do alot of this dom manipulation might be worth looking at jquery

$.each(result, function(key, value) {
  console.log(key+ ':' + value);
});

Yes Exactly, the only distinction is the fact it returns a value.

Simplification (not using expressions):

List<T>.ForEach Takes an action, it doesn't expect a return result.

So an Action<T> delegate would suffice.. say:

List<T>.ForEach(param => Console.WriteLine(param));

is the same as saying:

List<T>.ForEach(delegate(T param) { Console.WriteLine(param); });

the difference is that the param type and delegate decleration are inferred by usage and the braces aren't required on a simple inline method.

Where as

List<T>.Where Takes a function, expecting a result.

So an Function<T, bool> would be expected:

List<T>.Where(param => param.Value == SomeExpectedComparison);

which is the same as:

List<T>.Where(delegate(T param) { return param.Value == SomeExpectedComparison; });

You can also declare these methods inline and asign them to variables IE:

Action myAction = () => Console.WriteLine("I'm doing something Nifty!");

myAction();

or

Function<object, string> myFunction = theObject => theObject.ToString();

string myString = myFunction(someObject);

I hope this helps.

The right and standard way to do it is using classList. It is now widely supported in the latest version of most modern browsers:

ELEMENT.classList.remove("CLASS_NAME");

remove.onclick = () => {_x000D_
  const el = document.querySelector('#el');_x000D_
  if (el.classList.contains("red")) {_x000D_
    el.classList.remove("red");_x000D_
_x000D_
  }_x000D_
}

.red {_x000D_
  background: red_x000D_
}

<div id='el' class="red"> Test</div>_x000D_
<button id='remove'>Remove Class</button>

Documentation: https://developer.mozilla.org/en/DOM/element.classList

jQuery("[name='test']") 

Although you should avoid it and if possible select by ID (e.g. #myId) as this has better performance because it invokes the native getElementById.

In case you need to nest more than one null coalescing operation such as:

model?.data()?.first()

This is not a problem easily solved with or. It also cannot be solved with .get() which requires a dictionary type or similar (and cannot be nested anyway) or getattr() which will throw an exception when NoneType doesn't have the attribute.

The relevant pip considering adding null coalescing to the language is PEP 505 and the discussion relevant to the document is in the python-ideas thread.

Ajax (also AJAX) an acronym for Asynchronous JavaScript and XML) is a group of interrelated web development techniques used on the client-side to create asynchronous web applications. With Ajax, web applications can send data to, and retrieve data from, a server asynchronously Below is example code:

Jsp page java script function to submit data to servlet with two variable firstName and lastName:

function onChangeSubmitCallWebServiceAJAX()
    {
      createXmlHttpRequest();
      var firstName=document.getElementById("firstName").value;
      var lastName=document.getElementById("lastName").value;
      xmlHttp.open("GET","/AJAXServletCallSample/AjaxServlet?firstName="
      +firstName+"&lastName="+lastName,true)
      xmlHttp.onreadystatechange=handleStateChange;
      xmlHttp.send(null);

    }

Servlet to read data send back to jsp in xml format ( You could use text as well. Just you need to change response content to text and render data on javascript function.)

/**
 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
 */
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    String firstName = request.getParameter("firstName");
    String lastName = request.getParameter("lastName");

    response.setContentType("text/xml");
    response.setHeader("Cache-Control", "no-cache");
    response.getWriter().write("<details>");
    response.getWriter().write("<firstName>"+firstName+"</firstName>");
    response.getWriter().write("<lastName>"+lastName+"</lastName>");
    response.getWriter().write("</details>");
}

Finally, I solved it. Even though the solution is a bit lengthy, I think its the simplest. The solution is as follows:

1. Install Visual Studio 2008
2. Install the service Package 1 (SP1)
3. Install SQL Server 2008 r2

There is a better way that is safer and will not slow down your application. How Excel is set up, a cell can have either a value or a formula; the formula can not refer to its own cell. You end up with an infinite loop, since the new value would cause another calculation... . Use a helper column to calculate the value based on what you put in the other cell. For Example:

Column A is a True or False, Column B contains a monetary value, Column C contains the folowing formula: =B1

Now, to calculate that column B will be highlighted yellow in a conditional format only if Column A is True and Column B is greater than Zero...

=AND(A1=True,C1>0)

You can then choose to hide column C

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

Though this question already has sufficient answers, I thought somebody would want to know why this flag works in this peculiar manner, This is what I found in Android documentation

The currently running instance of activity B in the above example will either receive the new intent you are starting here in its onNewIntent() method, or be itself finished and restarted with the new intent.

If it has declared its launch mode to be "multiple" (the default) and you have not set FLAG_ACTIVITY_SINGLE_TOP in the same intent, then it will be finished and re-created; for all other launch modes or if FLAG_ACTIVITY_SINGLE_TOP is set then this Intent will be delivered to the current instance's onNewIntent().

So, Either,
1. Change the launchMode of the Activity A to something else from standard (ie. singleTask or something). Then your flag FLAG_ACTIVITY_CLEAR_TOP will not restart your Activity A.

or,

2. Use Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP as your flag. Then it will work the way you desire.

Don't build it if you can buy it.

I heard this quote recently, and it really seems fitting as a guide line. Ask yourself this... How much time was spent working on the file handling portion of your app? I suspect a fair amount of time was spent optimizing this code for performance. If you had been using a relational database all along, you would have spent considerably less time handling this portion of your application. You would have had more time for the true "business" aspect of your app.

Java - its independence is not only from the operating system, but also from the vendor.

Therefore, you should be able to deploy your application on different application servers. JPA is implemented in any Java EE- compliant application server and it allows to swap application servers, but then the implementation is also changing. A Hibernate application may be easier to deploy on a different application server.

Here is a jquery function that returns an object of any class or id on the page

var elementPosition = function(idClass) {
            var element = $(idClass);
            var offset = element.offset();

            return {
                'top': offset.top,
                'right': offset.left + element.outerWidth(),
                'bottom': offset.top + element.outerHeight(),
                'left': offset.left,
            };
        };


        console.log(elementPosition('#my-class-or-id'));

Use the continue keyword. Read here.

The continue statement skips the current iteration of a for, while , or do-while loop.

The statement you're executing is valid. The error seems to mean that Toad is including the trailing semicolon as part of the command, which does cause an ORA-00911 when it's included as part of a statement - since it is a statement separator in the client, not part of the statement itself.

It may be the following commented-out line that is confusing Toad (as described here); or it might be because you're trying to run everything as a single statement, in which case you can try to use the run script command (F9) instead of run statement (F5).

Just removing the commented-out line makes the problem go away, but if you also saw this with an actual commit then it's likely to be that you're using the wrong method to run the statements.

There is a bit more information about how Toad parses the semicolons in a comment on this related question, but I'm not familiar enough with Toad to go into more detail.

I used this to check if all the text boxes had numeric values:

if(!$.isNumeric($('input:text').val())) {
        alert("All the text boxes must have numeric values!");
        return false;
    }

or for one:

$.isNumeric($("txtBox").val());

Available with jQuery 1.7.

I did test your code and the only problem I could see was the lack of permission given to the directory you try to write the file in to.

Give "write" permission to the directory you need to put the file. In your case it is the current directory.

Use "chmod" in linux.

Add "Everyone" with "write" enabled to the security tab of the directory if you are in Windows.

I ran into this problem with templated classes. Here's a more general solution I had to use:

template class <T>
class myClass
{
    int myField;

    // Helper function accessing my fields
    void toString(std::ostream&) const;

    // Friend means operator<< can use private variables
    // It needs to be declared as a template, but T is taken
    template <class U>
    friend std::ostream& operator<<(std::ostream&, const myClass<U> &);
}

// Operator is a non-member and global, so it's not myClass<U>::operator<<()
// Because of how C++ implements templates the function must be
// fully declared in the header for the linker to resolve it :(
template <class U>
std::ostream& operator<<(std::ostream& os, const myClass<U> & obj)
{
  obj.toString(os);
  return os;
}

Now: * My toString() function can't be inline if it is going to be tucked away in cpp. * You're stuck with some code in the header, I couldn't get rid of it. * The operator will call the toString() method, it's not inlined.

The body of operator<< can be declared in the friend clause or outside the class. Both options are ugly. :(

Maybe I'm misunderstanding or missing something, but just forward-declaring the operator template doesn't link in gcc.

This works too:

template class <T>
class myClass
{
    int myField;

    // Helper function accessing my fields
    void toString(std::ostream&) const;

    // For some reason this requires using T, and not U as above
    friend std::ostream& operator<<(std::ostream&, const myClass<T> &)
    {
        obj.toString(os);
        return os;
    }
}

I think you can also avoid the templating issues forcing declarations in headers, if you use a parent class that is not templated to implement operator<<, and use a virtual toString() method.

If you are developing on Netbeans, you will not get the Third-Party add-ons. You can download the Skins directly from Samsung here: http://developer.samsung.com/android/tools-sdks

After download, unzip to ...\Android\android-sdk\add-ons[name of device]

Restart the Android SDK Manager, and the new device should be there under Extras.

It would be better to add the download site directly to the SDK...if anyone knows it, please post it.

I have always found the distinction between unsupervised and supervised learning to be arbitrary and a little confusing. There is no real distinction between the two cases, instead there is a range of situations in which an algorithm can have more or less 'supervision'. The existence of semi-supervised learning is an obvious examples where the line is blurred.

I tend to think of supervision as giving feedback to the algorithm about what solutions should be preferred. For a traditional supervised setting, such as spam detection, you tell the algorithm "don't make any mistakes on the training set"; for a traditional unsupervised setting, such as clustering, you tell the algorithm "points that are close to each other should be in the same cluster". It just so happens that, the first form of feedback is a lot more specific than the latter.

In short, when someone says 'supervised', think classification, when they say 'unsupervised' think clustering and try not to worry too much about it beyond that.

Here a case insensitive function since all those solutions above are case sensitive.

def Palindrome(string): 

  return (string.upper() == string.upper()[::-1]) 

This function will return a boolean value.

michael's suggestions works like a charm for me :) If you replace $http.post with $http.get, remember that the .get method accepts 2 parameters instead of 3... this is where is wasted my time... ;)

controller:

$http.get('/getdoc/' + $stateParams.id,     
{responseType:'arraybuffer'})
  .success(function (response) {
     var file = new Blob([(response)], {type: 'application/pdf'});
     var fileURL = URL.createObjectURL(file);
     $scope.content = $sce.trustAsResourceUrl(fileURL);
});

view:

<object ng-show="content" data="{{content}}" type="application/pdf" style="width: 100%; height: 400px;"></object>

You can hide StackNavigator header like this:

const Stack = createStackNavigator();
function StackScreen() {
    return (
        <Stack.Navigator
            screenOptions={{ headerShown: false }}>
            <Stack.Screen name="Login" component={Login} />
            <Stack.Screen name="Training" component={Training} />
            <Stack.Screen name="Course" component={Course} />
            <Stack.Screen name="Signup" component={Signup} />
        </Stack.Navigator>
    );
}

One should NEVER call System.exit(0) for these reasons:

1. It is a hidden "goto" and "gotos" break the control flow. Relying on hooks in this context is a mental mapping every developer in the team has to be aware of.

2. Quitting the program "normally" provides the same exit code to the operating system as System.exit(0) so it is redundant.

   If your program cannot quit "normally" you have lost control of your development [design]. You should have always full control of the system state.

3. Programming problems such as running threads that are not stopped normally become hidden.
4. You may encounter an inconsistent application state interrupting threads abnormally. (Refer to #3)

By the way: Returning other return codes than 0 does make sense if you want to indicate abnormal program termination.

You can use purrr as well, which is similar to apply family functions:

as.data.frame(purrr::map_chr(mtcars, class))
purrr::map_df(mtcars, class)

To add bold, italic and underline, just add the following to the font argument:

font=("Arial", 8, 'normal', 'bold', 'italic', 'underline')

Check if the Driver Connector jar matches the SQL version.

I was also getting the same error as I was using the

mySQl-connector-java-5.1.30.jar

I wanted to provide with a solution inspired by physics.

Imagine a force applied along the line and you are measuring the torque of the force about the point. If the torque is positive (counterclockwise) then the point is to the "left" of the line, but if the torque is negative the point is the "right" of the line.

So if the force vector equals the span of the two points defining the line

fx = x_2 - x_1
fy = y_2 - y_1

you test for the side of a point (px,py) based on the sign of the following test

var torque = fx*(py-y_1)-fy*(px-x_1)
if  torque>0  then
     "point on left side"
else if torque <0 then
     "point on right side"  
else
     "point on line"
end if

The Why

java.util.logging has a root logger that defaults to Level.INFO, and a ConsoleHandler attached to it that also defaults to Level.INFO. FINE is lower than INFO, so fine messages are not displayed by default.

Solution 1

Create a logger for your whole application, e.g. from your package name or use Logger.getGlobal(), and hook your own ConsoleLogger to it. Then either ask root logger to shut up (to avoid duplicate output of higher level messages), or ask your logger to not forward logs to root.

public static final Logger applog = Logger.getGlobal();
...

// Create and set handler
Handler systemOut = new ConsoleHandler();
systemOut.setLevel( Level.ALL );
applog.addHandler( systemOut );
applog.setLevel( Level.ALL );

// Prevent logs from processed by default Console handler.
applog.setUseParentHandlers( false ); // Solution 1
Logger.getLogger("").setLevel( Level.OFF ); // Solution 2

Solution 2

Alternatively, you may lower the root logger's bar.

You can set them by code:

Logger rootLog = Logger.getLogger("");
rootLog.setLevel( Level.FINE );
rootLog.getHandlers()[0].setLevel( Level.FINE ); // Default console handler

Or with logging configuration file, if you are using it:

.level = FINE
java.util.logging.ConsoleHandler.level = FINE

By lowering the global level, you may start seeing messages from core libraries, such as from some Swing or JavaFX components. In this case you may set a Filter on the root logger to filter out messages not from your program.

If you can look ahead but back, you could reverse the string first and then do a lookahead. Some more work will need to be done, of course.

To add a new file in SVN

svn add file_name
svn commit -m "text about changes..."

To add a new file in a directory in SVN

svn add directory_name/file_name
svn commit -m "text about changes"

To add all new files in a directory with some targets (files) are already versioned (added):

svn add directory_name/*
svn commit -m "text about changes"

Just use Date.parse() which returns a Number, then use new Date() to parse it:

var thedate = new Date(Date.parse("2011-07-14 11:23:00"));

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

The problem is with slashes: your variable contains them and the final command will be something like sed "s/string/path/to/something/g", containing way too many slashes.

Since sed can take any char as delimiter (without having to declare the new delimiter), you can try using another one that doesn't appear in your replacement string:

replacement="/my/path"
sed --expression "s@pattern@$replacement@"

Note that this is not bullet proof: if the replacement string later contains @ it will break for the same reason, and any backslash sequences like \1 will still be interpreted according to sed rules. Using | as a delimiter is also a nice option as it is similar in readability to /.

Answers

Q: What is a lambda expression in C++11?

A: Under the hood, it is the object of an autogenerated class with overloading operator() const. Such object is called closure and created by compiler. This 'closure' concept is near with the bind concept from C++11. But lambdas typically generate better code. And calls through closures allow full inlining.

Q: When would I use one?

A: To define "simple and small logic" and ask compiler perform generation from previous question. You give a compiler some expressions which you want to be inside operator(). All other stuff compiler will generate to you.

Q: What class of problem do they solve that wasn't possible prior to their introduction?

A: It is some kind of syntax sugar like operators overloading instead of functions for custom add, subrtact operations...But it save more lines of unneeded code to wrap 1-3 lines of real logic to some classes, and etc.! Some engineers think that if the number of lines is smaller then there is a less chance to make errors in it (I'm also think so)

Example of usage

auto x = [=](int arg1){printf("%i", arg1); };
void(*f)(int) = x;
f(1);
x(1);

Extras about lambdas, not covered by question. Ignore this section if you're not interest

1. Captured values. What you can to capture

1.1. You can reference to a variable with static storage duration in lambdas. They all are captured.

1.2. You can use lambda for capture values "by value". In such case captured vars will be copied to the function object (closure).

[captureVar1,captureVar2](int arg1){}

1.3. You can capture be reference. & -- in this context mean reference, not pointers.

   [&captureVar1,&captureVar2](int arg1){}

1.4. It exists notation to capture all non-static vars by value, or by reference

  [=](int arg1){} // capture all not-static vars by value

  [&](int arg1){} // capture all not-static vars by reference

1.5. It exists notation to capture all non-static vars by value, or by reference and specify smth. more. Examples: Capture all not-static vars by value, but by reference capture Param2

[=,&Param2](int arg1){} 

Capture all not-static vars by reference, but by value capture Param2

[&,Param2](int arg1){} 

2. Return type deduction

2.1. Lambda return type can be deduced if lambda is one expression. Or you can explicitly specify it.

[=](int arg1)->trailing_return_type{return trailing_return_type();}

If lambda has more then one expression, then return type must be specified via trailing return type. Also, similar syntax can be applied to auto functions and member-functions

3. Captured values. What you can not capture

3.1. You can capture only local vars, not member variable of the object.

4. ?onversions

4.1 !! Lambda is not a function pointer and it is not an anonymous function, but capture-less lambdas can be implicitly converted to a function pointer.

p.s.

1. More about lambda grammar information can be found in Working draft for Programming Language C++ #337, 2012-01-16, 5.1.2. Lambda Expressions, p.88

2. In C++14 the extra feature which has named as "init capture" have been added. It allow to perform arbitarily declaration of closure data members:

   auto toFloat = [](int value) { return float(value);};
   auto interpolate = [min = toFloat(0), max = toFloat(255)](int value)->float { return (value - min) / (max - min);};
   

You can do something like this:

 rspec/spec/features/controller/spec_file_name.rb
 rspec/spec/features/controller_name.rb         #run all the specs in this controller

Pickle uses different protocols to convert your data to a binary stream.

• In python 2 there are 3 different protocols (0, 1, 2) and the default is 0.

• In python 3 there are 5 different protocols (0, 1, 2, 3, 4) and the default is 3.

You must specify in python 3 a protocol lower than 3 in order to be able to load the data in python 2. You can specify the protocol parameter when invoking pickle.dump.

Everybody jumped on this one!!! I too made a fiddle:

RobAgar gets a point for pointing out white-space:nowrap first.

Couple of things here, you need overflow: hidden if you don't want to see the extra characters poking out into your layout.

Also, as mentioned, you could use white-space: pre (see EnderMB) keeping in mind that pre will not collapse white space whereas white-space: nowrap will.

By default any files you add to src/main/resources will be included in the jar.

If you need to change that behavior for whatever reason, you can do so by configuring sourceSets.

This part of the documentation has all the details

SevenZipSharp is another solution. Creates 7-zip archives...

If you use "hg remove b" against a file with "A" status, which means it has been added but not commited, Mercurial will respond:

  not removing b: file has been marked for add (use forget to undo)

This response is a very clear explication of the difference between remove and forget.

My understanding is that "hg forget" is for undoing an added but not committed file so that it is not tracked by version control; while "hg remove" is for taking out a committed file from version control.

This thread has a example for using hg remove against files of 7 different types of status.

On your click function, just add:

window.location.href = "The URL where you want to redirect";
$('#id').click(function(){
    window.location.href = "http://www.google.com";
});

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

I'm using WAS ND 7.0

My JVM need all the following arguments to be monitored in JConsole

    -Djavax.management.builder.initial= 
    -Dcom.sun.management.jmxremote 
    -Dcom.sun.management.jmxremote.port=8855 
    -Dcom.sun.management.jmxremote.authenticate=false 
    -Dcom.sun.management.jmxremote.ssl=false

All the remove commands didn't work for me what I did was to navigate there using the path provided in git and then deleting it manually.

Using Post call, worked for me.

RestClient restClient = new RestClient();

request.AddQueryParameter("refresh_token", "value");

restClient.BaseUrl = new System.Uri("https://oauth2.googleapis.com/token");

This is another late answer but i figured out a fairly simple way of placing the "bar" text in between the four squares. Here are the changes i made; In the bar section i wrapped the "bar" text within a center and div tags.

<header><center><div class="bar">bar</div></center></header>

And in the CSS section i created a "bar" class which is used in the div tag above. After adding this the bar text was centered between the four colored blocks.

.bar{
    position: relative;
}

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

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

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

Update 2016/6: For aspect ratio and positioning (ala CSS' "cover" method), check out:
Simulation background-size: cover in canvas

For those browsers that do support "position: fixed" you can simply use javascript (jQuery) to change the position to "fixed" when scrolling. This eliminates the jumpiness when scrolling with the $(window).scroll(function()) solutions listed here.

Ben Nadel demonstrates this in his tutorial: Creating A Sometimes-Fixed-Position Element With jQuery

i used the following method & it worked fine for me

$('#mybutton').click(function(){
        clearForm($('#mybutton').closest("form"));
    });

$('#mybutton').closest("form") did the trick for me.

In case you want to run a PowerShell script with Windows Task Scheduler, please follow the steps below:

1. Create a task

2. Set Program/Script to Powershell.exe

3. Set Arguments to -File "C:\xxx.ps1"

It's from another answer, How do I execute a PowerShell script automatically using Windows task scheduler?.

How about this (in you don't want an one liner) ?

for row in df.collect():
    d = row.asDict()
    s = "%d\t%s\t%s\n" % (d["int_column"], d["string_column"], d["string_column"])
    f.write(s)

f is a opened file descriptor. Also the separator is a TAB char, but it's easy to change to whatever you want.

categories_posts and categories_news start with substring 'categories_' then it is enough to check that developer_configurations_cms.cfg_name_unique starts with 'categories' instead of check if it contains the given substring. Translating all that into a query:

SELECT *
    FROM developer_configurations_cms

    WHERE developer_configurations_cms.cat_id = '1'
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%'
    AND developer_configurations_cms.cfg_name_unique NOT LIKE 'categories%'

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

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

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

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

You wrote:

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

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

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

To disable this feature use flex-shrink: 0.

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

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

I've a problem with H2 version 1.4.190 remote connection to inMemory (as well as in file) with Connection is broken: "unexpected status 16843008" until do not downgrade to 1.3.176. See Grails accessing H2 TCP server hangs

Figured this out. Pretty simple:

 new PDO("sqlsrv:server=[sqlservername];Database=[sqlserverdbname]",  "[username]", "[password]");

For me, getattr is easiest to explain this way:

It allows you to call methods based on the contents of a string instead of typing the method name.

For example, you cannot do this:

obj = MyObject()
for x in ['foo', 'bar']:
    obj.x()

because x is not of the type builtin, but str. However, you CAN do this:

obj = MyObject()
for x in ['foo', 'bar']:
    getattr(obj, x)()

It allows you to dynamically connect with objects based on your input. I've found it useful when dealing with custom objects and modules.

You don't have to save and restore the state by yourself anymore. If you set unique ID in xml and recyclerView.setSaveEnabled(true) (true by default) system will automatically do it. Here is more about this: http://trickyandroid.com/saving-android-view-state-correctly/

Assume the new file is "/home/satya/app/app_specific_env" and the file contents are as follows

#!bin/bash

export FAV_NUMBER="2211"

Append this file reference to ~/.bashrc file

source /home/satya/app/app_specific_env

When ever you restart the machine or relogin, try echo $FAV_NUMBER in the terminal. It will output the value.

Just in case if you want to see the effect right away, source ~/.bashrc in the command line.

As rule-of-thumb there are two kinds of members:

• public surface: visible from an external assembly (public, protected, and internal protected): caller is not trusted, so parameter validation, method documentation, etc. is needed.
• private surface: not visible from an external assembly (private and internal, or internal classes): caller is generally trusted, so parameter validation, method documentation, etc. may be omitted.

I found that when you create an input filter to avoid entry of unwanted characters, pasting such characters into the edit text is having no effect. So this sort of solves my problem as well.

It took me some time to figure this out: My php-file was encoded in UTF-8. And the BOM prevented header location to work properly. In Notepad++ I set the file encoding to "UTF-8 without BOM" and the problem was gone.

When you use prototype, the function will only be loaded only once into memory (independently on the amount of objects you create) and you can override the function whenever you want.

I tried to use more than two windows using the Rushy Panchal example above. The intent was to have the change to call more windows with different widgets in them. The butnew function creates different buttons to open different windows. You pass as argument the name of the class containing the window (the second argument is nt necessary, I put it there just to test a possible use. It could be interesting to inherit from another window the widgets in common.

Open the new window only once

To avoid having the chance to press multiple times the button having multiple windows... that are the same window, I made this script (take a look at this page too)

import tkinter as tk


def new_window1():
    global win1
    try:
        if win1.state() == "normal": win1.focus()
    except:
        win1 = tk.Toplevel()
        win1.geometry("300x300+500+200")
        win1["bg"] = "navy"
        lb = tk.Label(win1, text="Hello")
        lb.pack()


win = tk.Tk()
win.geometry("200x200+200+100")
button = tk.Button(win, text="Open new Window")
button['command'] = new_window1
button.pack()
win.mainloop()

mkdir [-switch] foldername

-p is a switch which is optional, it will create subfolder and parent folder as well even parent folder doesn't exist.

From the man page:

-p, --parents no error if existing, make parent directories as needed

Example:

mkdir -p storage/framework/{sessions,views,cache}

This will create subfolder sessions,views,cache inside framework folder irrespective of 'framework' was available earlier or not.

Its not right to set default value in View. The View should perform display work, not more. This action breaks ideology of MVC pattern. So the right place to set defaults - create method of controller class.

Starting Mongo 4.4, we can achieve this join within an aggregation pipeline by coupling the new $unionWith aggregation stage with $group's new $accumulator operator:

// > db.books.find()
//   [{ user: 1, book: "a" }, { user: 1, book: "b" }, { user: 2, book: "c" }]
// > db.movies.find()
//   [{ user: 1, movie: "g" }, { user: 2, movie: "h" }, { user: 2, movie: "i" }]
db.users.aggregate([
  { $unionWith: "books"  },
  { $unionWith: "movies" },
  { $group: {
    _id: "$user",
    user: {
      $accumulator: {
        accumulateArgs: ["$name", "$book", "$movie"],
        init: function() { return { books: [], movies: [] } },
        accumulate: function(user, name, book, movie) {
          if (name) user.name = name;
          if (book) user.books.push(book);
          if (movie) user.movies.push(movie);
          return user;
        },
        merge: function(userV1, userV2) {
          if (userV2.name) userV1.name = userV2.name;
          userV1.books.concat(userV2.books);
          userV1.movies.concat(userV2.movies);
          return userV1;
        },
        lang: "js"
      }
    }
  }}
])
// { _id: 1, user: { books: ["a", "b"], movies: ["g"], name: "x" } }
// { _id: 2, user: { books: ["c"], movies: ["h", "i"], name: "y" } }

• $unionWith combines records from the given collection within documents already in the aggregation pipeline. After the 2 union stages, we thus have all users, books and movies records within the pipeline.

• We then $group records by $user and accumulate items using the $accumulator operator allowing custom accumulations of documents as they get grouped:

  • the fields we're interested in accumulating are defined with accumulateArgs.
  • init defines the state that will be accumulated as we group elements.
  • the accumulate function allows performing a custom action with a record being grouped in order to build the accumulated state. For instance, if the item being grouped has the book field defined, then we update the books part of the state.
  • merge is used to merge two internal states. It's only used for aggregations running on sharded clusters or when the operation exceeds memory limits.

Path changes appear to be persistent if you set the SHELL variable in your makefile first:

SHELL := /bin/bash
PATH := bin:$(PATH)

test all:
    x

I don't know if this is desired behavior or not.

Flexbox-based tables can easily be sorted by using flexbox property "order".

Here's an example:

function sortTable() {_x000D_
  let table = document.querySelector("#table")_x000D_
  let children = [...table.children]_x000D_
  let sortedArr = children.map(e => e.innerText).sort((a, b) => a.localeCompare(b));_x000D_
_x000D_
  children.forEach(child => {_x000D_
    child.style.order = sortedArr.indexOf(child.innerText)_x000D_
  })_x000D_
}_x000D_
_x000D_
document.querySelector("#sort").addEventListener("click", sortTable)

#table {_x000D_
  display: flex;_x000D_
  flex-direction: column_x000D_
}

<div id="table">_x000D_
  <div>Melissa</div>_x000D_
  <div>Justin</div>_x000D_
  <div>Judy</div>_x000D_
  <div>Skipper</div>_x000D_
  <div>Alex</div>_x000D_
</div>_x000D_
<button id="sort"> sort </button>

Explanation

The sortTable function extracts the data of the table into an array, which is then sorted in alphabetic order. After that we loop through the table items and assign the CSS property order equal to index of an item's data in our sorted array.

This example shows how to use a list of multiprocessing.Pipe instances to return strings from an arbitrary number of processes:

import multiprocessing

def worker(procnum, send_end):
    '''worker function'''
    result = str(procnum) + ' represent!'
    print result
    send_end.send(result)

def main():
    jobs = []
    pipe_list = []
    for i in range(5):
        recv_end, send_end = multiprocessing.Pipe(False)
        p = multiprocessing.Process(target=worker, args=(i, send_end))
        jobs.append(p)
        pipe_list.append(recv_end)
        p.start()

    for proc in jobs:
        proc.join()
    result_list = [x.recv() for x in pipe_list]
    print result_list

if __name__ == '__main__':
    main()

Output:

0 represent!
1 represent!
2 represent!
3 represent!
4 represent!
['0 represent!', '1 represent!', '2 represent!', '3 represent!', '4 represent!']

This solution uses fewer resources than a multiprocessing.Queue which uses

• a Pipe
• at least one Lock
• a buffer
• a thread

or a multiprocessing.SimpleQueue which uses

• a Pipe
• at least one Lock

It is very instructive to look at the source for each of these types.

request.getRequestURI().substring(request.getContextPath().length())

Yes, it is legal to have a primary key being a foreign key. This is a rare construct, but it applies for:

• a 1:1 relation. The two tables cannot be merged in one because of different permissions and privileges only apply at table level (as of 2017, such a database would be odd).

• a 1:0..1 relation. Profile may or may not exist, depending on the user type.

• performance is an issue, and the design acts as a partition: the profile table is rarely accessed, hosted on a separate disk or has a different sharding policy as compared to the users table. Would not make sense if the underlining storage is columnar.

What is the difference between <init-param> and <context-param> !?

Single servlet versus multiple servlets.

Other Answers give details, but here is the summary:

A web app, that is, a “context”, is made up of one or more servlets.

• <init-param> defines a value available to a single specific servlet within a context.
• <context-param> defines a value available to all the servlets within a context.

You need to access the matches in order to get at the SDI number. Here is a function that will do it (assuming there is only 1 SDI number per cell).

For the regex, I used "sdi followed by a space and one or more numbers". You had "sdi followed by a space and zero or more numbers". You can simply change the + to * in my pattern to go back to what you had.

Function ExtractSDI(ByVal text As String) As String

Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")

RE.pattern = "(sdi \d+)"
RE.Global = True
RE.IgnoreCase = True
Set allMatches = RE.Execute(text)

If allMatches.count <> 0 Then
    result = allMatches.Item(0).submatches.Item(0)
End If

ExtractSDI = result

End Function

If a cell may have more than one SDI number you want to extract, here is my RegexExtract function. You can pass in a third paramter to seperate each match (like comma-seperate them), and you manually enter the pattern in the actual function call:

Ex) =RegexExtract(A1, "(sdi \d+)", ", ")

Here is:

Function RegexExtract(ByVal text As String, _
                      ByVal extract_what As String, _
                      Optional seperator As String = "") As String

Dim i As Long, j As Long
Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")

RE.pattern = extract_what
RE.Global = True
Set allMatches = RE.Execute(text)

For i = 0 To allMatches.count - 1
    For j = 0 To allMatches.Item(i).submatches.count - 1
        result = result & seperator & allMatches.Item(i).submatches.Item(j)
    Next
Next

If Len(result) <> 0 Then
    result = Right(result, Len(result) - Len(seperator))
End If

RegexExtract = result

End Function

*Please note that I have taken "RE.IgnoreCase = True" out of my RegexExtract, but you could add it back in, or even add it as an optional 4th parameter if you like.

A very simple way to have a cygwin shell and corresponding subshells to operate with administrator privileges is to change the properties of the link which opens the initial shell.

The following is valid for Windows 7+ (perhaps for previous versions too, but I've not checked)

I usually start the cygwin shell from a cygwin-link in the start button (or desktop). Then, I changed the properties of the cygwin-link in the tabs

/Compatibility/Privilege Level/

and checked the box,

"Run this program as an administrator"

This allows the cygwin shell to open with administrator privileges and the corresponding subshells too.

team! For execute SQL-query from your Servlet you should add JDBC jar library in folder

WEB-INF/lib

After this you could call driver, example :

Class.forName("oracle.jdbc.OracleDriver");

Now Y can use connection to DB-server

==> 73!

Whenever you're confused, I would suggest consulting the Javadoc as the first place for your clarification.

From the javadoc about System, here's what the doc says:

public final class System
extends Object

The System class contains several useful class fields and methods. It cannot be instantiated.
Among the facilities provided by the System class are standard input, standard output, and error output streams; access to externally defined properties and environment variables; a means of loading files and libraries; and a utility method for quickly copying a portion of an array.

Since:
JDK1.0

Regarding System.out

public static final PrintStream out
The "standard" output stream. This stream is already open and ready to accept output data. Typically this stream corresponds to display output or another output destination specified by the host environment or user.
For simple stand-alone Java applications, a typical way to write a line of output data is:

     System.out.println(data)

For the more unusual charts: http://thejit.org/

d <- 5
for(i in 1:10) { 
 nam <- paste("A", i, sep = "")
 assign(nam, rnorm(3)+d)
}

More info here or even here!

You can use cut with a delimiter like this:

with space delim:

cut -d " " -f1-100,1000-1005 infile.csv > outfile.csv

with tab delim:

cut -d$'\t' -f1-100,1000-1005 infile.csv > outfile.csv

I gave you the version of cut in which you can extract a list of intervals...

Hope it helps!

After installing macos mojave, had to wipe mysql folder under /usr/local/var/mysql and then reinstall via brew install mysql otherwise permission related things would come up all over the place.

You need to return your promise to the calling function.

islogged:function(){
    var cUid=sessionService.get('uid');
    alert("in loginServce, cuid is "+cUid);
    var $checkSessionServer=$http.post('data/check_session.php?cUid='+cUid);
    $checkSessionServer.then(function(){
        alert("session check returned!");
        console.log("checkSessionServer is "+$checkSessionServer);
    });
    return $checkSessionServer; // <-- return your promise to the calling function
}

Step1 Check your jdk is installed. and variable path is setted. Step2 unistall your eclipes and reinstall it. other wise It will continue to be a problem

For .Net core i had many problems using SSH.net and also its deprecated. I tried a few other libraries, even for other programming languages. But i found a very good alternative. https://stackoverflow.com/a/64443701/8529170

There is HTML and URI encodings. & is & encoded in HTML while %26 is & in URI encoding.

So before URI encoding your string you might want to HTML decode and then URI encode it :)

var div = document.createElement('div');
div.innerHTML = '&AndOtherHTMLEncodedStuff';
var htmlDecoded = div.firstChild.nodeValue;
var urlEncoded = encodeURIComponent(htmlDecoded);

result %26AndOtherHTMLEncodedStuff

Hope this saves you some time

You are using getData() method as void.

You can not return values from void.

This is how I do it:

>>> import traceback
>>> try:
...   int('k')
... except:
...   var = traceback.format_exc()
... 
>>> print var
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
ValueError: invalid literal for int() with base 10: 'k'

You should however take a look at the traceback documentation, as you might find there more suitable methods, depending to how you want to process your variable afterwards...

the best way to calculate the equation is simplified. That is, find the maximum divisor between two numbers and divide:

ex.

1920:1080 maximum common divisor 120 = 16:9
1024:768  maximum common divisor 256 = 4:3
1280:768  maximum common divisor 256 = 5:3

may happen also some approaches

<ui:include>

Most basic way is <ui:include>. The included content must be placed inside <ui:composition>.

Kickoff example of the master page /page.xhtml:

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h:head>
        <title>Include demo</title>
    </h:head>
    <h:body>
        <h1>Master page</h1>
        <p>Master page blah blah lorem ipsum</p>
        <ui:include src="/WEB-INF/include.xhtml" />
    </h:body>
</html>

The include page /WEB-INF/include.xhtml (yes, this is the file in its entirety, any tags outside <ui:composition> are unnecessary as they are ignored by Facelets anyway):

<ui:composition 
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h2>Include page</h2>
    <p>Include page blah blah lorem ipsum</p>
</ui:composition>
  

This needs to be opened by /page.xhtml. Do note that you don't need to repeat <html>, <h:head> and <h:body> inside the include file as that would otherwise result in invalid HTML.

You can use a dynamic EL expression in <ui:include src>. See also How to ajax-refresh dynamic include content by navigation menu? (JSF SPA).

<ui:define>/<ui:insert>

A more advanced way of including is templating. This includes basically the other way round. The master template page should use <ui:insert> to declare places to insert defined template content. The template client page which is using the master template page should use <ui:define> to define the template content which is to be inserted.

Master template page /WEB-INF/template.xhtml (as a design hint: the header, menu and footer can in turn even be <ui:include> files):

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h:head>
        <title><ui:insert name="title">Default title</ui:insert></title>
    </h:head>
    <h:body>
        <div id="header">Header</div>
        <div id="menu">Menu</div>
        <div id="content"><ui:insert name="content">Default content</ui:insert></div>
        <div id="footer">Footer</div>
    </h:body>
</html>

Template client page /page.xhtml (note the template attribute; also here, this is the file in its entirety):

<ui:composition template="/WEB-INF/template.xhtml"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">

    <ui:define name="title">
        New page title here
    </ui:define>

    <ui:define name="content">
        <h1>New content here</h1>
        <p>Blah blah</p>
    </ui:define>
</ui:composition>

This needs to be opened by /page.xhtml. If there is no <ui:define>, then the default content inside <ui:insert> will be displayed instead, if any.

<ui:param>

You can pass parameters to <ui:include> or <ui:composition template> by <ui:param>.

<ui:include ...>
    <ui:param name="foo" value="#{bean.foo}" />
</ui:include>

<ui:composition template="...">
    <ui:param name="foo" value="#{bean.foo}" />
    ...
</ui:composition >

Inside the include/template file, it'll be available as #{foo}. In case you need to pass "many" parameters to <ui:include>, then you'd better consider registering the include file as a tagfile, so that you can ultimately use it like so <my:tagname foo="#{bean.foo}">. See also When to use <ui:include>, tag files, composite components and/or custom components?

You can even pass whole beans, methods and parameters via <ui:param>. See also JSF 2: how to pass an action including an argument to be invoked to a Facelets sub view (using ui:include and ui:param)?

Design hints

The files which aren't supposed to be publicly accessible by just entering/guessing its URL, need to be placed in /WEB-INF folder, like as the include file and the template file in above example. See also Which XHTML files do I need to put in /WEB-INF and which not?

There doesn't need to be any markup (HTML code) outside <ui:composition> and <ui:define>. You can put any, but they will be ignored by Facelets. Putting markup in there is only useful for web designers. See also Is there a way to run a JSF page without building the whole project?

The HTML5 doctype is the recommended doctype these days, "in spite of" that it's a XHTML file. You should see XHTML as a language which allows you to produce HTML output using a XML based tool. See also Is it possible to use JSF+Facelets with HTML 4/5? and JavaServer Faces 2.2 and HTML5 support, why is XHTML still being used.

CSS/JS/image files can be included as dynamically relocatable/localized/versioned resources. See also How to reference CSS / JS / image resource in Facelets template?

You can put Facelets files in a reusable JAR file. See also Structure for multiple JSF projects with shared code.

For real world examples of advanced Facelets templating, check the src/main/webapp folder of Java EE Kickoff App source code and OmniFaces showcase site source code.

XCODE 9 AND ABOVE

You need to modify the method GetData() and add your "experimental" code there, and return t1.

Well then: welcome to the R world ;-)

Here you go

Setting up the code

urls <- c(
    "http://stat.ethz.ch/R-manual/R-devel/library/base/html/connections.html",
    "http://en.wikipedia.org/wiki/Xz",
    "xxxxx"
)
readUrl <- function(url) {
    out <- tryCatch(
        {
            # Just to highlight: if you want to use more than one 
            # R expression in the "try" part then you'll have to 
            # use curly brackets.
            # 'tryCatch()' will return the last evaluated expression 
            # in case the "try" part was completed successfully

            message("This is the 'try' part")

            readLines(con=url, warn=FALSE) 
            # The return value of `readLines()` is the actual value 
            # that will be returned in case there is no condition 
            # (e.g. warning or error). 
            # You don't need to state the return value via `return()` as code 
            # in the "try" part is not wrapped inside a function (unlike that
            # for the condition handlers for warnings and error below)
        },
        error=function(cond) {
            message(paste("URL does not seem to exist:", url))
            message("Here's the original error message:")
            message(cond)
            # Choose a return value in case of error
            return(NA)
        },
        warning=function(cond) {
            message(paste("URL caused a warning:", url))
            message("Here's the original warning message:")
            message(cond)
            # Choose a return value in case of warning
            return(NULL)
        },
        finally={
        # NOTE:
        # Here goes everything that should be executed at the end,
        # regardless of success or error.
        # If you want more than one expression to be executed, then you 
        # need to wrap them in curly brackets ({...}); otherwise you could
        # just have written 'finally=<expression>' 
            message(paste("Processed URL:", url))
            message("Some other message at the end")
        }
    )    
    return(out)
}

Applying the code

Additional remarks

tryCatch

tryCatch returns the value associated to executing expr unless there's an error or a warning. In this case, specific return values (see return(NA) above) can be specified by supplying a respective handler function (see arguments error and warning in ?tryCatch). These can be functions that already exist, but you can also define them within tryCatch() (as I did above).

The implications of choosing specific return values of the handler functions

As we've specified that NA should be returned in case of error, the third element in y is NA. If we'd have chosen NULL to be the return value, the length of y would just have been 2 instead of 3 as lapply() will simply "ignore" return values that are NULL. Also note that if you don't specify an explicit return value via return(), the handler functions will return NULL (i.e. in case of an error or a warning condition).

"Undesired" warning message

As warn=FALSE doesn't seem to have any effect, an alternative way to suppress the warning (which in this case isn't really of interest) is to use

suppressWarnings(readLines(con=url))

instead of

readLines(con=url, warn=FALSE)

Multiple expressions

Note that you can also place multiple expressions in the "actual expressions part" (argument expr of tryCatch()) if you wrap them in curly brackets (just like I illustrated in the finally part).

SELECT Id   'PatientId',
       ISNULL(CONVERT(varchar(50),ParentId),'')  'ParentId'
FROM Patients

ISNULL always tries to return a result that has the same data type as the type of its first argument. So, if you want the result to be a string (varchar), you'd best make sure that's the type of the first argument.

COALESCE is usually a better function to use than ISNULL, since it considers all argument data types and applies appropriate precedence rules to determine the final resulting data type. Unfortunately, in this case, uniqueidentifier has higher precedence than varchar, so that doesn't help.

(It's also generally preferred because it extends to more than two arguments)

Go into your css and add that to it then will automatically block the submission of your formular as long as you have submit input if you no longer want it you can delete it or type activate and deactivate instead

 input:disabled {
        background: gainsboro;
      }
      input[value]:disabled {
        color: whitesmoke;
      }

This way worked for me:

adding the path that you like:

export PYTHONPATH=$PYTHONPATH:/path/you/want/to/add

checking: you can run 'export' cmd and check the output or you can check it using this cmd:

python -c "import sys; print(sys.path)"

This sort of thing is one of the logistical reasons why Abort is deprecated. First and foremost, do not use Thread.Abort() to cancel or stop a thread if at all possible. Abort() should only be used to forcefully kill a thread that is not responding to more peaceful requests to stop in a timely fashion.

That being said, you need to provide a shared cancellation indicator that one thread sets and waits while the other thread periodically checks and gracefully exits. .NET 4 includes a structure designed specifically for this purpose, the CancellationToken.

Well I couldn't find a Django way, but I did find a python way from inside my model:

def format_price(self):
    import locale
    locale.setlocale(locale.LC_ALL, '')
    return locale.format('%d', self.price, True)

rsubmit;
options missing=0;
ods listing close;
ods csv file='\\FILE_PATH_and_Name_of_report.csv';

proc sql;
SELECT *
FROM `YOUR_FINAL_TABLE_NAME';
quit;
ods csv close;

endrsubmit;

Add rich comparison operators to the object class, then use sort() method of the list.
See rich comparison in python.

Update: Although this method would work, I think solution from Triptych is better suited to your case because way simpler.

No such thing, probably just a macro for int

You need a root node

There IS A POINT in introducing MAX_FILE_SIZE client side hidden form field.

php.ini can limit uploaded file size. So, while your script honors the limit imposed by php.ini, different HTML forms can further limit an uploaded file size. So, when uploading video, form may limit* maximum size to 10MB, and while uploading photos, forms may put a limit of just 1mb. And at the same time, the maximum limit can be set in php.ini to suppose 10mb to allow all this.

Although this is not a fool proof way of telling the server what to do, yet it can be helpful.

• HTML does'nt limit anything. It just forwards the server all form variable including MAX_FILE_SIZE and its value.

Hope it helped someone.

TypeScript supports structural typing (also called duck typing), meaning that types are compatible when they share the same members. Your problem is that Apple and Pear don't share all their members, which means that they are not compatible. They are however compatible to another type that has only the isDecayed: boolean member. Because of structural typing, you don' need to inherit Apple and Pear from such an interface.

There are different ways to assign such a compatible type:

Assign type during variable declaration

This statement is implicitly typed to Apple[] | Pear[]:

const fruits = fruitBasket[key];

You can simply use a compatible type explicitly in in your variable declaration:

const fruits: { isDecayed: boolean }[] = fruitBasket[key];

For additional reusability, you can also define the type first and then use it in your declaration (note that the Apple and Pear interfaces don't need to be changed):

type Fruit = { isDecayed: boolean };
const fruits: Fruit[] = fruitBasket[key];

Cast to compatible type for the operation

The problem with the given solution is that it changes the type of the fruits variable. This might not be what you want. To avoid this, you can narrow the array down to a compatible type before the operation and then set the type back to the same type as fruits:

const fruits: fruitBasket[key];
const freshFruits = (fruits as { isDecayed: boolean }[]).filter(fruit => !fruit.isDecayed) as typeof fruits;

Or with the reusable Fruit type:

type Fruit = { isDecayed: boolean };
const fruits: fruitBasket[key];
const freshFruits = (fruits as Fruit[]).filter(fruit => !fruit.isDecayed) as typeof fruits;

The advantage of this solution is that both, fruits and freshFruits will be of type Apple[] | Pear[].

I don't think the accepted solution handles the case where the error text is reported on stderr. From my testing the exception's output attribute did not contain the results from stderr and the docs warn against using stderr=PIPE in check_output(). Instead, I would suggest one small improvement to J.F Sebastian's solution by adding stderr support. We are, after all, trying to handle errors and stderr is where they are often reported.

from subprocess import Popen, PIPE

p = Popen(['bitcoin', 'sendtoaddress', ..], stdout=PIPE, stderr=PIPE)
output, error = p.communicate()
if p.returncode != 0: 
   print("bitcoin failed %d %s %s" % (p.returncode, output, error))

Incase anyone needs it for multiple parent. Refer id 2 which has multiple parents
