For this I have created an "WinHttp.WinHttpRequest.5.1" object.

Send a post request with some data from Excel using VBA:

Dim LoginRequest As Object
Set LoginRequest = CreateObject("WinHttp.WinHttpRequest.5.1")
LoginRequest.Open "POST", "http://...", False
LoginRequest.setRequestHeader "Content-type", "application/x-www-form-urlencoded"
LoginRequest.send ("key1=value1&key2=value2")

Send a get request with token authentication from Excel using VBA:

Dim TCRequestItem As Object
Set TCRequestItem = CreateObject("WinHttp.WinHttpRequest.5.1")
TCRequestItem.Open "GET", "http://...", False
TCRequestItem.setRequestHeader "Content-Type", "application/xml"
TCRequestItem.setRequestHeader "Accept", "application/xml"
TCRequestItem.setRequestHeader "Authorization", "Bearer " & token
TCRequestItem.send

Don't forget to seed the RNG with srand() first.

For a non-angular general answer for those who land on this question from Google:

Every time you face this error its probably because of a memory leak or difference between how Node <= 10 and Node > 10 manage memory. Usually just increasing the memory allocated to Node will allow your program to run but may not actually solve the real problem and the memory used by the node process could still exceed the new memory you allocate. I'd advise profiling memory usage in your node process when it starts running or updating to node > 10.

I had a memory leak. Here is a great article on debugging memory leaks in node.

That said, to increase the memory, in the terminal where you run your Node process:

export NODE_OPTIONS="--max-old-space-size=8192"

where values of max-old-space-size can be: [2048, 4096, 8192, 16384] etc

[UPDATE] More examples for further clarity:

export NODE_OPTIONS="--max-old-space-size=5120" #increase to 5gb
export NODE_OPTIONS="--max-old-space-size=6144" #increase to 6gb
export NODE_OPTIONS="--max-old-space-size=7168" #increase to 7gb
export NODE_OPTIONS="--max-old-space-size=8192" #increase to 8gb

# and so on...

# formula:
export NODE_OPTIONS="--max-old-space-size=(X * 1024)" #increase to Xgb

# Note: it doesn't have to be multiples of 1024. 
# max-old-space-size can be any number of memory megabytes(MB) you have available.

Update 2020: I have a new answer that replaces this, now 8-years-old, one: https://stackoverflow.com/a/61177330/278976

On Linux, I tried cpp-netlib, libcurl, curlpp, urdl, boost::asio and considered Qt (but turned it down based on the license). All of these were either incomplete for this use, had sloppy interfaces, had poor documentation, were unmaintained or didn't support https.

Then, at the suggestion of https://stackoverflow.com/a/1012577/278976, I tried POCO. Wow, I wish I had seen this years ago. Here's an example of making an HTTP GET request with POCO:

https://stackoverflow.com/a/26026828/2817595

POCO is free, open source (boost license). And no, I don't have any affiliation with the company; I just really like their interfaces. Great job guys (and gals).

Hope this helps someone... it took me three days to try all of these libraries out.

Chrome 52+ supports alpha hex:

background: #56ff0077;

There is also read_csv in Pandas, which is fast and supports non-comma column separators and automatic typing by column:

import pandas as pd
df = pd.read_csv('your_file',sep='\t')

It can be converted to a NumPy array if you prefer that type with:

import numpy as np
arr = np.array(df)

This is by far the easiest and most mature text import approach I've come across.

When I use my Debian vim that is not integrated with Gnome (vim --version | grep clip # shows no clipboard support), I can copy to the clipboard after holding the Shift key and selecting the text with the mouse, just like with any other curses program. As I figured from a comment by @Conner, it's the terminal (gnome-terminal in my case) that turns off its mouse event reporting when it senses my Shift press. I guess curses-based programs can receive mouse events after sending a certain Escape sequence to the terminal.

The :not negation pseudo class

The negation CSS pseudo-class, :not(X), is a functional notation taking a simple selector X as an argument. It matches an element that is not represented by the argument. X must not contain another negation selector.

You can use :not to exclude any subset of matched elements, ordered as you would normal CSS selectors.

Simple example: excluding by class

div:not(.class)

Would select all div elements without the class .class

div:not(.class) {_x000D_
  color: red;_x000D_
}

<div>Make me red!</div>_x000D_
<div class="class">...but not me...</div>

Complex example: excluding by type / hierarchy

:not(div) > div

Would select all div elements which arent children of another div

div {_x000D_
  color: black_x000D_
}_x000D_
:not(div) > div {_x000D_
  color: red;_x000D_
}

<div>Make me red!</div>_x000D_
<div>_x000D_
  <div>...but not me...</div>_x000D_
</div>

Complex example: chaining pseudo selectors

With the notable exception of not being able to chain/nest :not selectors and pseudo elements, you can use in conjunction with other pseudo selectors.

div {_x000D_
  color: black_x000D_
}_x000D_
:not(:nth-child(2)){_x000D_
  color: red;_x000D_
}

<div>_x000D_
  <div>Make me red!</div>_x000D_
  <div>...but not me...</div>_x000D_
</div>

Browser Support, etc.

:not is a CSS3 level selector, the main exception in terms of support is that it is IE9+

The spec also makes an interesting point:

the :not() pseudo allows useless selectors to be written. For instance :not(*|*), which represents no element at all, or foo:not(bar), which is equivalent to foo but with a higher specificity.

Or try to check your mainActivity.xml you make sure that this one
xmlns:app="http://schemas.android.com/apk/res-auto"hereis included

Since 2.3 version of Gson library the JsonArray class have a 'set' method.

Here's an simple example:

JsonArray array = new JsonArray();
array.add(new JsonPrimitive("Red"));
array.add(new JsonPrimitive("Green"));
array.add(new JsonPrimitive("Blue"));

array.remove(2);
array.set(0, new JsonPrimitive("Yelow"));

For another as Latin languages for example Cyrillic you can use something like this:

FileReader fr = new FileReader("src/text.txt", StandardCharsets.UTF_8);

and be sure that your .txt file is saved with UTF-8 (but not as default ANSI) format. Cheers!

one of the approach if you want to get all user_id that satisfies all conditions is:

SELECT DISTINCT user_id FROM table WHERE ancestry IN ('England', '...', '...') GROUP BY user_id HAVING count(*) = <number of conditions that has to be satisfied> 

etc. If you need to take all user_ids that satisfies at least one condition, then you can do

SELECT DISTINCT user_id from table where ancestry IN ('England', 'France', ... , '...')

I am not aware if there is something similar to IN but that joins conditions with AND instead of OR

If you want to get stdout and stderr back (including extracting it from the CalledProcessError in the event that one occurs), use the following:

import subprocess

command = ["ls", "-l"]
try:
    output = subprocess.check_output(command, stderr=subprocess.STDOUT).decode()
    success = True 
except subprocess.CalledProcessError as e:
    output = e.output.decode()
    success = False

print(output)

This is Python 2 and 3 compatible.

If your command is a string rather than an array, prefix this with:

import shlex
command = shlex.split(command)

Your method signature makes no sense, are you sure it isn't a typo? I'm not clear how it's even compiling, though perhaps you're getting warnings that you're ignoring?

How many parameters do you expect this method to take?

Try this

For red color,

<string name="hello_worldRed"><![CDATA[<b><font color=#FF0000>Hello world!</font></b>]]></string>

For blue,

<string name="hello_worldBlue"><![CDATA[<b><font color=#0000FF>Hello world!</font></b>]]></string>

In java code,

//red color text
TextView redColorTextView = (TextView)findViewById(R.id.redText);
String redString = getResources().getString(R.string.hello_worldRed)
redColorTextView.setText(Html.fromHtml(redString));

//Blue color text
TextView blueColorTextView = (TextView)findViewById(R.id.blueText);
String blueString = getResources().getString(R.string.hello_worldBlue)
blueColorTextView.setText(Html.fromHtml(blueString));

Daniel Imms answer is excellent in regards to applying your CSS rotation to an inner element. However, it is possible to accomplish the end goal in a way that does not require JavaScript and works with longer strings of text.

Typically the whole reason to have vertical text in the first table column is to fit a long line of text in a short horizontal space and to go alongside tall rows of content (as in your example) or multiple rows of content (which I'll use in this example).

By using the ".rotate" class on the parent TD tag, we can not only rotate the inner DIV, but we can also set a few CSS properties on the parent TD tag that will force all of the text to stay on one line and keep the width to 1.5em. Then we can use some negative margins on the inner DIV to make sure that it centers nicely.

td {_x000D_
    border: 1px black solid;_x000D_
    padding: 5px;_x000D_
}_x000D_

  text-align: center;_x000D_
  white-space: nowrap;_x000D_

One thing to keep in mind with this solution is that it does not work well if the height of the row (or spanned rows) is shorter than the vertical text in the first column. It works best if you're spanning multiple rows or you have a lot of content creating tall rows.

Have fun playing around with this on jsFiddle.

You can pass a string with your list and use a prepared statements to run a query, e.g. -

DELIMITER $$

CREATE PROCEDURE GetFruits(IN fruitArray VARCHAR(255))
BEGIN

  SET @sql = CONCAT('SELECT * FROM Fruits WHERE Name IN (', fruitArray, ')');
  PREPARE stmt FROM @sql;
  EXECUTE stmt;
  DEALLOCATE PREPARE stmt;

END
$$

DELIMITER ;

How to use:

SET @fruitArray = '\'apple\',\'banana\'';
CALL GetFruits(@fruitArray);

UPDATE: 2019-12-30

It seem that this tool is no longer working! [Request for update!]

UPDATE 2019-01-06: You can bypass X-Frame-Options in an <iframe> using my X-Frame-Bypass Web Component. It extends the IFrame element by using multiple CORS proxies and it was tested in the latest Firefox and Chrome.

You can use it as follows:

1. (Optional) Include the Custom Elements with Built-in Extends polyfill for Safari:

   <script src="https://unpkg.com/@ungap/custom-elements-builtin"></script>
   

2. Include the X-Frame-Bypass JS module:

   <script type="module" src="x-frame-bypass.js"></script>
   

3. Insert the X-Frame-Bypass Custom Element:

   <iframe is="x-frame-bypass" src="https://example.org/"></iframe>
   

You could use AJAX to call this controller action. For example if you are using jQuery you might use the $.ajax() method:

<script type="text/javascript">
    $.ajax({
        url: '@Url.Action("NameOfYourAction")',
        type: 'GET',
        cache: false,
        success: function(result) {
            // you could use the result.values dictionary here
        }
    });
</script>

Had a similar problem, actually I ended up in probing the existence of some file within my web.

probePath would be the relative URL to the file you want to check for (kind of a marker if you're now at the correct location), e.g. 'assets/images/thisImageAlwaysExists.png'

<script type='text/javascript'>
  function configExists(url) {
    var req = new XMLHttpRequest();
    req.open('GET', url, false); 
    req.send();
    return req.status==200;
  }

  var probePath = '...(some file that must exist)...';
  var origin = document.location.origin;
  var pathSegments = document.location.pathname.split('/');

  var basePath = '/'
  var configFound = false;
  for (var i = 0; i < pathSegments.length; i++) {
    var segment = pathSegments[i];
    if (segment.length > 0) {
      basePath = basePath + segment + '/';
    }
    var fullPath = origin + basePath + probePath;
    configFound = configExists(fullPath);
    if (configFound) {
      break;
    }
  }

  document.write("<base href='" + (configFound ? basePath : '/') + "' />");
</script>

I just faced the same issue and these are the steps that I follow in order to provide Python version. I wanted to run my PySpark jobs with Python 2.7 instead of 2.6.

1. Go to the folder where $SPARK_HOME is pointing to (in my case is /home/cloudera/spark-2.1.0-bin-hadoop2.7/)

2. Under folder conf, there is a file called spark-env.sh. In case you have a file called spark-env.sh.template you will need to copy the file to a new file called spark-env.sh.

3. Edit the file and write the next three lines

   export PYSPARK_PYTHON=/usr/local/bin/python2.7

   export PYSPARK_DRIVER_PYTHON=/usr/local/bin/python2.7

   export SPARK_YARN_USER_ENV="PYSPARK_PYTHON=/usr/local/bin/python2.7"

4. Save it and launch your application again :)

In that way, if you download a new Spark standalone version, you can set the Python version which you want to run PySpark to.

Use the keyword and, not & because & is a bit operator.

Be careful with this... just so you know, in Java and C++, the & operator is ALSO a bit operator. The correct way to do a boolean comparison in those languages is &&. Similarly | is a bit operator, and || is a boolean operator. In Python and and or are used for boolean comparisons.

The alert() dialog is not rendered in HTML, and thus the HTML you have embedded is meaningless.

You'd need to use a custom modal to achieve that.

Here is an example that shows the differences, which will help with the explanation.

var s1 = new String("Avoid newing things where possible");
var s2 = "A string, in TypeScript of type 'string'";
var s3: string;

String is the JavaScript String type, which you could use to create new strings. Nobody does this as in JavaScript the literals are considered better, so s2 in the example above creates a new string without the use of the new keyword and without explicitly using the String object.

string is the TypeScript string type, which you can use to type variables, parameters and return values.

Additional notes...

Currently (Feb 2013) Both s1 and s2 are valid JavaScript. s3 is valid TypeScript.

Use of String. You probably never need to use it, string literals are universally accepted as being the correct way to initialise a string. In JavaScript, it is also considered better to use object literals and array literals too:

var arr = []; // not var arr = new Array();
var obj = {}; // not var obj = new Object();

If you really had a penchant for the string, you could use it in TypeScript in one of two ways...

var str: String = new String("Hello world"); // Uses the JavaScript String object
var str: string = String("Hello World"); // Uses the TypeScript string type

You have to loop over the input array and add rules for each input as described here: Loop Over Rules

Here is a some code for ya:

$input = Request::all();
$rules = [];

foreach($input['name'] as $key => $val)
{
    $rules['name.'.$key] = 'required|distinct|min:3';
}

$rules['amount'] = 'required|integer|min:1';
$rules['description'] = 'required|string';

$validator = Validator::make($input, $rules);

//Now check validation:
if ($validator->fails()) 
{ 
  /* do something */ 
}

Its faster with MUTT command

echo "Body Of the Email"  | mutt -a "File_Attachment.csv" -s "Daily Report for $(date)"  -c [email protected] [email protected] -y

1. -c email cc list
2. -s subject list
3. -y to send the mail

Your error is in UpdaterServiceManager in onCreate and showNotification method.

You are trying to show notification from Service using Activity Context. Whereas Every Service has its own Context, just use the that. You don't need to pass a Service an Activity's Context.I don't see why you need a specific Activity's Context to show Notification.

Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.

You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

Try the following:

foo(*values)

This can be found in the Python docs as Unpacking Argument Lists.

For reference (this is the correct answer):

Inside a .d.ts definition file

type MyGlobalFunctionType = (name: string) => void

If you work in the browser, you add members to the browser's window context by reopening Window's interface:

interface Window {
  myGlobalFunction: MyGlobalFunctionType
}

Same idea for NodeJS:

declare module NodeJS {
  interface Global {
    myGlobalFunction: MyGlobalFunctionType
  }
}

Now you declare the root variable (that will actually live on window or global)

declare const myGlobalFunction: MyGlobalFunctionType;

Then in a regular .ts file, but imported as side-effect, you actually implement it:

global/* or window */.myGlobalFunction = function (name: string) {
  console.log("Hey !", name);
};

And finally use it elsewhere in the codebase, with either:

global/* or window */.myGlobalFunction("Kevin");

myGlobalFunction("Kevin");

funny, that in the most answer you create a box with the text (or object), instead of it create the text (or object) div and under that a box with 100% width (or at least what it should) and with height what equal with your "border" px... So, i think this is the most simple and perfect answer:

<h3>Your Text</h3><div class="border-shadow"></div>

and the css:

    .shadow {
        width:100%;
        height:1px; // = "border height (without the shadow)!"
        background:#000; // = "border color!"
        -webkit-box-shadow: 0px 1px 8px 1px rgba(0,0,0,1); // rbg = "border shadow color!"
        -moz-box-shadow: 0px 1px 8px 1px rgba(0,0,0,1); // rbg = "border shadow color!"
        box-shadow: 0px 1px 8px 1px rgba(0,0,0,1); // rbg = "border shadow color!"

}

Here you can experiment with the radius, etc. easy: https://www.cssmatic.com/box-shadow

You just need to escape the period:

a <- c("NM_020506.1","NM_020519.1","NM_001030297.2","NM_010281.2","NM_011419.3", "NM_053155.2")

The short answer to this question is that none of these values are a reliable indicator of how much memory an executable is actually using, and none of them are really appropriate for debugging a memory leak.

Private Bytes refer to the amount of memory that the process executable has asked for - not necessarily the amount it is actually using. They are "private" because they (usually) exclude memory-mapped files (i.e. shared DLLs). But - here's the catch - they don't necessarily exclude memory allocated by those files. There is no way to tell whether a change in private bytes was due to the executable itself, or due to a linked library. Private bytes are also not exclusively physical memory; they can be paged to disk or in the standby page list (i.e. no longer in use, but not paged yet either).

Working Set refers to the total physical memory (RAM) used by the process. However, unlike private bytes, this also includes memory-mapped files and various other resources, so it's an even less accurate measurement than the private bytes. This is the same value that gets reported in Task Manager's "Mem Usage" and has been the source of endless amounts of confusion in recent years. Memory in the Working Set is "physical" in the sense that it can be addressed without a page fault; however, the standby page list is also still physically in memory but not reported in the Working Set, and this is why you might see the "Mem Usage" suddenly drop when you minimize an application.

Virtual Bytes are the total virtual address space occupied by the entire process. This is like the working set, in the sense that it includes memory-mapped files (shared DLLs), but it also includes data in the standby list and data that has already been paged out and is sitting in a pagefile on disk somewhere. The total virtual bytes used by every process on a system under heavy load will add up to significantly more memory than the machine actually has.

So the relationships are:

• Private Bytes are what your app has actually allocated, but include pagefile usage;
• Working Set is the non-paged Private Bytes plus memory-mapped files;
• Virtual Bytes are the Working Set plus paged Private Bytes and standby list.

There's another problem here; just as shared libraries can allocate memory inside your application module, leading to potential false positives reported in your app's Private Bytes, your application may also end up allocating memory inside the shared modules, leading to false negatives. That means it's actually possible for your application to have a memory leak that never manifests itself in the Private Bytes at all. Unlikely, but possible.

Private Bytes are a reasonable approximation of the amount of memory your executable is using and can be used to help narrow down a list of potential candidates for a memory leak; if you see the number growing and growing constantly and endlessly, you would want to check that process for a leak. This cannot, however, prove that there is or is not a leak.

One of the most effective tools for detecting/correcting memory leaks in Windows is actually Visual Studio (link goes to page on using VS for memory leaks, not the product page). Rational Purify is another possibility. Microsoft also has a more general best practices document on this subject. There are more tools listed in this previous question.

I hope this clears a few things up! Tracking down memory leaks is one of the most difficult things to do in debugging. Good luck.

I work a lot with CSS panel and it's too slow in Safari Web Inspector. Apple knows about this problem and promise to fix this bug with freezes, except this thing web tools is much more powerful and convenient than firebug in mozilla, so waiting for fix.

Do as Rabbott says, or if you refuse jQuery:

<script type="text/javascript">
function get_action() { // inside script tags
  return form_action;
}
</script>

<form action="" onsubmit="this.action=get_action();">
...
</form>

The problem with taking IEnumerable as a parameter is that it tells callers "I wish to enumerate this". It doesn't tell them how many times you wish to enumerate.

I can change the objects parameter to be List and then avoid the possible multiple enumeration but then I don't get the highest object that I can handle.

The goal of taking the highest object is noble, but it leaves room for too many assumptions. Do you really want someone to pass a LINQ to SQL query to this method, only for you to enumerate it twice (getting potentially different results each time?)

The semantic missing here is that a caller, who perhaps doesn't take time to read the details of the method, may assume you only iterate once - so they pass you an expensive object. Your method signature doesn't indicate either way.

By changing the method signature to IList/ICollection, you will at least make it clearer to the caller what your expectations are, and they can avoid costly mistakes.

Otherwise, most developers looking at the method might assume you only iterate once. If taking an IEnumerable is so important, you should consider doing the .ToList() at the start of the method.

It's a shame .NET doesn't have an interface that is IEnumerable + Count + Indexer, without Add/Remove etc. methods, which is what I suspect would solve this problem.

This might work:

git checkout 56e05f
echo ref: refs/heads/master > .git/HEAD
git commit

validChars can be any construct, but I decided to select based on ascii code ranges removing control chars. In this example, it is a 12 character string.

string validChars = String.Join("", Enumerable.Range(33, (126 - 33)).Where(i => !(new int[] { 34, 38, 39, 44, 60, 62, 96 }).Contains(i)).Select(i => { return (char)i; }));
string.Join("", Enumerable.Range(1, 12).Select(i => { return validChars[(new Random(Guid.NewGuid().GetHashCode())).Next(0, validChars.Length - 1)]; }))

Can't you originally get the data as a JSONObject?

Perhaps parse the string as both a JSONObject and a JSONArray in the first place? Where is the JSON string coming from?

I'm not sure that it is possible to convert a JsonArray into a JsonObject.

I presume you are using the following from json.org

• JSONObject.java
  A JSONObject is an unordered collection of name/value pairs. Its external form is a string wrapped in curly braces with colons between the names and values, and commas between the values and names. The internal form is an object having get() and opt() methods for accessing the values by name, and put() methods for adding or replacing values by name. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.

• JSONArray.java
  A JSONArray is an ordered sequence of values. Its external form is a string wrapped in square brackets with commas between the values. The internal form is an object having get() and opt() methods for accessing the values by index, and put() methods for adding or replacing values. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.

I think you should try this

For my issue, I had to zero out the log:

sudo bash -c ' > /Applications/XAMPP/xamppfiles/logs/php_error_log '

Since swift 3.0 there is more convenient way: #imageLiterals here is text example. And below animated example from here:

Find out two pieces of information

• Whats the hostname or IP of the target ssh server
• What port is the ssh daemon listening on (default is port 22)

$> telnet <hostname or ip> <port>

Assuming the daemon is up and running and listening on that port it should etablish a telnet session. Likely causes:

• The ssh daemon is not running
• The host is blocking the target port with its software firewall
• Some intermediate network device is blocking or filtering the target port
• The ssh daemon is listening on a non standard port
• A TCP wrapper is configured and is filtering out your source host

Numpy matrices are strictly 2-dimensional, while numpy arrays (ndarrays) are N-dimensional. Matrix objects are a subclass of ndarray, so they inherit all the attributes and methods of ndarrays.

The main advantage of numpy matrices is that they provide a convenient notation for matrix multiplication: if a and b are matrices, then a*b is their matrix product.

import numpy as np

a = np.mat('4 3; 2 1')
b = np.mat('1 2; 3 4')
print(a)
# [[4 3]
#  [2 1]]
print(b)
# [[1 2]
#  [3 4]]
print(a*b)
# [[13 20]
#  [ 5  8]]

On the other hand, as of Python 3.5, NumPy supports infix matrix multiplication using the @ operator, so you can achieve the same convenience of matrix multiplication with ndarrays in Python >= 3.5.

import numpy as np

a = np.array([[4, 3], [2, 1]])
b = np.array([[1, 2], [3, 4]])
print(a@b)
# [[13 20]
#  [ 5  8]]

Both matrix objects and ndarrays have .T to return the transpose, but matrix objects also have .H for the conjugate transpose, and .I for the inverse.

In contrast, numpy arrays consistently abide by the rule that operations are applied element-wise (except for the new @ operator). Thus, if a and b are numpy arrays, then a*b is the array formed by multiplying the components element-wise:

c = np.array([[4, 3], [2, 1]])
d = np.array([[1, 2], [3, 4]])
print(c*d)
# [[4 6]
#  [6 4]]

To obtain the result of matrix multiplication, you use np.dot (or @ in Python >= 3.5, as shown above):

print(np.dot(c,d))
# [[13 20]
#  [ 5  8]]

The ** operator also behaves differently:

print(a**2)
# [[22 15]
#  [10  7]]
print(c**2)
# [[16  9]
#  [ 4  1]]

Since a is a matrix, a**2 returns the matrix product a*a. Since c is an ndarray, c**2 returns an ndarray with each component squared element-wise.

There are other technical differences between matrix objects and ndarrays (having to do with np.ravel, item selection and sequence behavior).

The main advantage of numpy arrays is that they are more general than 2-dimensional matrices. What happens when you want a 3-dimensional array? Then you have to use an ndarray, not a matrix object. Thus, learning to use matrix objects is more work -- you have to learn matrix object operations, and ndarray operations.

Writing a program that mixes both matrices and arrays makes your life difficult because you have to keep track of what type of object your variables are, lest multiplication return something you don't expect.

In contrast, if you stick solely with ndarrays, then you can do everything matrix objects can do, and more, except with slightly different functions/notation.

If you are willing to give up the visual appeal of NumPy matrix product notation (which can be achieved almost as elegantly with ndarrays in Python >= 3.5), then I think NumPy arrays are definitely the way to go.

PS. Of course, you really don't have to choose one at the expense of the other, since np.asmatrix and np.asarray allow you to convert one to the other (as long as the array is 2-dimensional).

There is a synopsis of the differences between NumPy arrays vs NumPy matrixes here.

Yet another example for the A.B.C approach is the Eclipse Bundle Versioning. Eclipse bundles rather have a fourth segment:

In Eclipse, version numbers are composed of four (4) segments: 3 integers and a string respectively named major.minor.service.qualifier. Each segment captures a different intent:

• the major segment indicates breakage in the API
• the minor segment indicates "externally visible" changes
• the service segment indicates bug fixes and the change of development stream
• the qualifier segment indicates a particular build

I am using CDN for my project and as part of fallback handling, i was using below code,

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script type="text/javascript">
                if ((typeof jQuery == 'undefined')) {
                    document.write(unescape("%3Cscript src='/Responsive/Scripts/jquery-1.9.1.min.js' type='text/javascript'%3E%3C/script%3E"));   
                }
</script>

Just to verify, i removed CDN reference and execute the code. Its broken and it's never entered into if loop as typeof jQuery is coming as function instead of undefined .

This is because of cached older version of jquery 1.6.1 which return function and break my code because i am using jquery 1.9.1. As i need exact version of jquery, i modified code as below,

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript">
            if ((typeof jQuery == 'undefined') || (jQuery.fn.jquery != "1.9.1")) {
                document.write(unescape("%3Cscript src='/Responsive/Scripts/jquery-1.9.1.min.js' type='text/javascript'%3E%3C/script%3E"));   
            }
</script>

I needed to search for usernames that are similar to each other, and what Ned Batchelder said was incredibly helpful. However, I found I had cleaner output when I used re.compile to create my re search term:

pattern = re.compile(r"("+username+".*):(.*?):(.*?):(.*?):(.*)"
matches = re.findall(pattern, lines)

Output can be printed using the following:

print(matches[1]) # prints one whole matching line (in this case, the first line)
print(matches[1][3]) # prints the fourth character group (established with the parentheses in the regex statement) of the first line.

Well I am running into the same problem and couldn't get any perfect solution. It's just a workaround. I am wondering how Google didn't think about flavors...? And i hope they will propose soon a better solution.

What I am doing:

I have two flavors, in each one I put the corresponding google-services.json : src/flavor1/google-services.json and src/flavor2/google-services.json .

Then in build gradle I copy the file depending on the flavor to the app/ directory:

android {

// set build flavor here to get the right gcm configuration.
//def myFlavor = "flavor1"
def myFlavor = "flavor2"

if (myFlavor.equals("flavor1")) {
    println "--> flavor1 copy!"
    copy {
        from 'src/flavor1/'
        include '*.json'
        into '.'
    }
} else {
    println "--> flavor2 copy!"
    copy {
        from 'src/flavor2/'
        include '*.json'
        into '.'
    }
}

// other stuff
}

Limitation: you will have to change myFlavor manually in gradle each time you want to run for a different flavor (because it's hardcoded).

I tried many ways to get the current build flavor like afterEvaluate close... couldn't get any better solution until now.

Update, Another solution: one google-services.json for all the flavors:

You can also, have different package names for each flavor and then in the google developer console you don't have to create two different apps for each flavor, but just two different clients in the same app. Then you will have only one google-services.json that contains your both clients. Of course, this depends on how you're implementing the backend of your flavors. If they're not separated then this solution will not help you.

For anyone reading this in 2015: if you happened to install the package ruby2.0, you need to install the matching ruby2.0-dev to get the appropriate Ruby headers. The same goes for ruby2.1 and ruby2.2, etc. For example:

$ sudo apt-get install ruby2.2-dev

Generally RuntimeExceptions are exceptions that can be prevented programmatically. E.g NullPointerException, ArrayIndexOutOfBoundException. If you check for null before calling any method, NullPointerException would never occur. Similarly ArrayIndexOutOfBoundException would never occur if you check the index first. RuntimeException are not checked by the compiler, so it is clean code.

EDIT : These days people favor RuntimeException because the clean code it produces. It is totally a personal choice.

It sounds to me like you want to be able to easily pass a string created using printf-style formatting to the function you already have that takes a simple string. You can create a wrapper function using stdarg.h facilities and vsnprintf() (which may not be readily available, depending on your compiler/platform):

#include <stdarg.h>
#include <stdio.h>

// a function that accepts a string:

void foo( char* s);

// You'd like to call a function that takes a format string 
//  and then calls foo():

void foofmt( char* fmt, ...)
{
    char buf[100];     // this should really be sized appropriately
                       // possibly in response to a call to vsnprintf()
    va_list vl;
    va_start(vl, fmt);

    vsnprintf( buf, sizeof( buf), fmt, vl);

    va_end( vl);

    foo( buf);
}



int main()
{
    int val = 42;

    foofmt( "Some value: %d\n", val);
    return 0;
}

For platforms that don't provide a good implementation (or any implementation) of the snprintf() family of routines, I've successfully used a nearly public domain snprintf() from Holger Weiss.

Try remove scrollChildLayout from its parent view first?

scrollview.removeView(scrollChildLayout)

Or remove all the child from the parent view, and add them again.

scrollview.removeAllViews()

I found this works:

window = Tk()
window.title('Window')

Maybe this helps?

As already mentioned this can't be done with floats, they can't inherit heights, they're unaware of their siblings so for example the side two floats don't know the height of the centre content, so they can't inherit from anything.

Usually inherited height has to come from either an element which has an explicit height or if height: 100%; has been passed down through the display tree to it.. The only thing I'm aware of that passes on height which hasn't come from top of the "tree" is an absolutely positioned element - so you could for example absolutely position all the top right bottom left sides and corners (you know the height and width of the corners anyway) And as you seem to know the widths (of left/right borders) and heights of top/bottom) borders, and the widths of the top/bottom centers, are easy at 100% - the only thing that needs calculating is the height of the right/left sides if the content grows -

This you can do, even without using all four positioning co-ordinates which IE6 /7 doesn't support

I've put up an example based on what you gave, it does rely on a fixed width (your frame), but I think it could work with a flexible width too? the uses of this could be cool for those fancy image borders we can't get support for until multiple background images or image borders become fully available.. who knows, I was playing, so just sticking it out there!

proof of concept example is here

I know this is a little old, but this but here is a concise function for counting regex patterns.

def regex_cnt(string, pattern):
    return len(re.findall(pattern, string))

string = 'abc123'

regex_cnt(string, '[0-9]')

Here is what i am trying to do in my projects:

• separate data and schema and default data.

The database configuration is stored in configuration file that is not under version control (.gitignore)

The database defaults (for setting up new Projects) is a simple SQL file under version control.

For the database schema create a database schema dump under the version control.

The most common way is to have update scripts that contains SQL Statements, (ALTER Table.. or UPDATE). You also need to have a place in your database where you save the current version of you schema)

Take a look at other big open source database projects (piwik,or your favorite cms system), they all use updatescripts (1.sql,2.sql,3.sh,4.php.5.sql)

But this a very time intensive job, you have to create, and test the updatescripts and you need to run a common updatescript that compares the version and run all necessary update scripts.

So theoretically (and thats what i am looking for) you could dumped the the database schema after each change (manually, conjob, git hooks (maybe before commit)) (and only in some very special cases create updatescripts)

After that in your common updatescript (run the normal updatescripts, for the special cases) and then compare the schemas (the dump and current database) and then automatically generate the nessesary ALTER Statements. There some tools that can do this already, but haven't found yet a good one.

This is how can you have automatic & flexible createDate/lastModified fields using triggers:

First define them like this:

CREATE TABLE `entity` (
  `entityid` int(11) NOT NULL AUTO_INCREMENT,
  `createDate` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
  `lastModified` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
  `name` varchar(255) DEFAULT NULL,
  `comment` text,
  PRIMARY KEY (`entityid`),
)

Then add these triggers:

DELIMITER ;;
CREATE trigger entityinsert BEFORE INSERT ON entity FOR EACH ROW BEGIN SET NEW.createDate=IF(ISNULL(NEW.createDate) OR NEW.createDate='0000-00-00 00:00:00', CURRENT_TIMESTAMP, IF(NEW.createDate<CURRENT_TIMESTAMP, NEW.createDate, CURRENT_TIMESTAMP));SET NEW.lastModified=NEW.createDate; END;;
DELIMITER ;
CREATE trigger entityupdate BEFORE UPDATE ON entity FOR EACH ROW SET NEW.lastModified=IF(NEW.lastModified<OLD.lastModified, OLD.lastModified, CURRENT_TIMESTAMP);

• If you insert without specifying createDate or lastModified, they will be equal and set to the current timestamp.
• If you update them without specifying createDate or lastModified, the lastModified will be set to the current timestamp.

But here's the nice part:

• If you insert, you can specify a createDate older than the current timestamp, allowing imports from older times to work well (lastModified will be equal to createDate).
• If you update, you can specify a lastModified older than the previous value ('0000-00-00 00:00:00' works well), allowing to update an entry if you're doing cosmetic changes (fixing a typo in a comment) and you want to keep the old lastModified date. This will not modify the lastModified date.

There seem to be differences between the two ways to access a git repository i.e. using either SSH or HTTPS. For me, I encountered the error because I was trying to push my local repository using SSH.

The problem can simply be solved by clicking the clone button on the landing page of your project and the copying the HTTPS link and replacing it to the SSH link appearing with the format "git@gitlab...".

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

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

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

For clarity, I added a diagram.

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

• npm run start
• npm run build

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

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

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

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

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

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

It may well be that you're running WordPress core tests, and have recently upgraded your PhpUnit to version 6. If that's the case, then the recent change to namespacing in PhpUnit will have broken your code.

Fortunately, there's a patch to the core tests at https://core.trac.wordpress.org/changeset/40547 which will work around the problem. It also includes changes to travis.yml, which you may not have in your setup; if that's the case then you'll need to edit the .diff file to ignore the Travis patch.

1. Download the "Unified Diff" patch from the bottom of https://core.trac.wordpress.org/changeset/40547

2. Edit the patch file to remove the Travis part of the patch if you don't need that. Delete from the top of the file to just above this line:

   Index: /branches/4.7/tests/phpunit/includes/bootstrap.php
   

3. Save the diff in the directory above your /includes/ directory - in my case this was the Wordpress directory itself

4. Use the Unix patch tool to patch the files. You'll also need to strip the first few slashes to move from an absolute to a relative directory structure. As you can see from point 3 above, there are five slashes before the include directory, which a -p5 flag will get rid of for you.

   $ cd [WORDPRESS DIRECTORY]
   $ patch -p5 < changeset_40547.diff 
   

After I did this my tests ran correctly again.

Say your table is called t1 and your primary-key is called id
First, create the sequence:

create sequence t1_seq start with 1 increment by 1 nomaxvalue; 

Then create a trigger that increments upon insert:

create trigger t1_trigger
before insert on t1
for each row
   begin
     select t1_seq.nextval into :new.id from dual;
   end;

I just found an interesting solution to this issue. I was creating spans which contain information based on the return from a web service. I thought about trying to put a link around the span so that if I clicked on it, the "a" would capture the click.

But I was trying to capture the click with the span... so I thought why not do this when I created the span.

var span = $('<span id="something" data-href="'+url+'" />');

I then bound a click handler to the span which created a link based on the 'data-href' attribute:

span.click(function(e) {
    e.stopPropagation();
    var href = $(this).attr('data-href');
    var link = $('<a href="http://' + href + '" />');
    link.attr('target', '_blank');
    window.open(link.attr('href'));
});

This successfully allowed me to click on a span and open a new window with a proper url.

You can also use the info provided by a php exception, it's an elegant solution:

function GetCallingMethodName(){
    $e = new Exception();
    $trace = $e->getTrace();
    //position 0 would be the line that called this function so we ignore it
    $last_call = $trace[1];
    print_r($last_call);
}

function firstCall($a, $b){
    theCall($a, $b);
}

function theCall($a, $b){
    GetCallingMethodName();
}

firstCall('lucia', 'php');

And you get this... (voilà!)

Array
(
    [file] => /home/lufigueroa/Desktop/test.php
    [line] => 12
    [function] => theCall
    [args] => Array
        (
            [0] => lucia
            [1] => php
        )

)

The easiest option is to start a windows forms project, then change the output-type to Console Application. Alternatively, just add a reference to System.Windows.Forms.dll, and start coding:

using System.Windows.Forms;

[STAThread]
static void Main() {
    Application.EnableVisualStyles();
    Application.Run(new Form()); // or whatever
}

The important bit is the [STAThread] on your Main() method, required for full COM support.

I have been using python requests for async calls against github's gist API for some time.

For an example, see the code here:

https://github.com/davidthewatson/flasgist/blob/master/views.py#L60-72

This style of python may not be the clearest example, but I can assure you that the code works. Let me know if this is confusing to you and I will document it.

if you set the onclick via html you need to removeAttr ($(this).removeAttr('onclick'))

if you set it via jquery (as the after the first click in my examples above) then you need to unbind($(this).unbind('click'))

assert is a debugging tool that will cause the program to throw an AssertionFailed exception if the condition is not true. In this case, the program will throw an exception if either of the two conditions following it evaluate to false. Generally speaking, assert should not be used in production code

<script>
    setTimeout(function(){
        window.location.href = 'form2.html';
    }, 5000);
</script>

And for home page add only '/'

<script>
    setTimeout(function(){
        window.location.href = '/';

You cannot directly change a form's validity. If all the descendant inputs are valid, the form is valid, if not, then it is not.

What you should do is to set the validity of the input element. Like so;

addItem.capabilities.$setValidity("youAreFat", false);

Now the input (and so the form) is invalid. You can also see which error causes invalidation.

addItem.capabilities.errors.youAreFat == true;

Another way to identify the correct SDK is to install Android Studio, create a new project, go to project structure, SDK Location and find where the SDK was installed.

I found using the default installation process on a mac that the SDK home folder was in the /Users/'yourUser'/Library/Android/sdk folder. Make sure you have enabled your Mac to view the Library folder.

Above, you mean OR not AND. Example of AND: 110 & 011 == 010 which is neither of the things you're looking for.

For OR, just have 2 cases without the break on the 1st. Eg:

case 'a':
case 'A':
  // do stuff
  break;

What if the incoming changes are the ones you want? I'm unable to run svn resolve --accept theirs-full

What parsers and lexers have in common:

1. They read symbols of some alphabet from their input.

   • Hint: The alphabet doesn't necessarily have to be of letters. But it has to be of symbols which are atomic for the language understood by parser/lexer.
   • Symbols for the lexer: ASCII characters.
   • Symbols for the parser: the particular tokens, which are terminal symbols of their grammar.

2. They analyse these symbols and try to match them with the grammar of the language they understood.
   

   • Here's where the real difference usually lies. See below for more.
   • Grammar understood by lexers: regular grammar (Chomsky's level 3).
   • Grammar understood by parsers: context-free grammar (Chomsky's level 2).

3. They attach semantics (meaning) to the language pieces they find.

   • Lexers attach meaning by classifying lexemes (strings of symbols from the input) as the particular tokens. E.g. All these lexemes: *, ==, <=, ^ will be classified as "operator" token by the C/C++ lexer.
   • Parsers attach meaning by classifying strings of tokens from the input (sentences) as the particular nonterminals and building the parse tree. E.g. all these token strings: [number][operator][number], [id][operator][id], [id][operator][number][operator][number] will be classified as "expression" nonterminal by the C/C++ parser.

4. They can attach some additional meaning (data) to the recognized elements.

   • When a lexer recognizes a character sequence constituting a proper number, it can convert it to its binary value and store with the "number" token.
   • Similarly, when a parser recognize an expression, it can compute its value and store with the "expression" node of the syntax tree.

5. They all produce on their output a proper sentences of the language they recognize.

   • Lexers produce tokens, which are sentences of the regular language they recognize. Each token can have an inner syntax (though level 3, not level 2), but that doesn't matter for the output data and for the one which reads them.
   • Parsers produce syntax trees, which are representations of sentences of the context-free language they recognize. Usually it's only one big tree for the whole document/source file, because the whole document/source file is a proper sentence for them. But there aren't any reasons why parser couldn't produce a series of syntax trees on its output. E.g. it could be a parser which recognizes SGML tags sticked into plain-text. So it'll tokenize the SGML document into a series of tokens: [TXT][TAG][TAG][TXT][TAG][TXT]....

As you can see, parsers and tokenizers have much in common. One parser can be a tokenizer for other parser, which reads its input tokens as symbols from its own alphabet (tokens are simply symbols of some alphabet) in the same way as sentences from one language can be alphabetic symbols of some other, higher-level language. For example, if * and - are the symbols of the alphabet M (as "Morse code symbols"), then you can build a parser which recognizes strings of these dots and lines as letters encoded in the Morse code. The sentences in the language "Morse Code" could be tokens for some other parser, for which these tokens are atomic symbols of its language (e.g. "English Words" language). And these "English Words" could be tokens (symbols of the alphabet) for some higher-level parser which understands "English Sentences" language. And all these languages differ only in the complexity of the grammar. Nothing more.

So what's all about these "Chomsky's grammar levels"? Well, Noam Chomsky classified grammars into four levels depending on their complexity:

• Level 3: Regular grammars

  They use regular expressions, that is, they can consist only of the symbols of alphabet (a,b), their concatenations (ab,aba,bbb etd.), or alternatives (e.g. a|b).
  They can be implemented as finite state automata (FSA), like NFA (Nondeterministic Finite Automaton) or better DFA (Deterministic Finite Automaton).
  Regular grammars can't handle with nested syntax, e.g. properly nested/matched parentheses (()()(()())), nested HTML/BBcode tags, nested blocks etc. It's because state automata to deal with it should have to have infinitely many states to handle infinitely many nesting levels.

• Level 2: Context-free grammars

  They can have nested, recursive, self-similar branches in their syntax trees, so they can handle with nested structures well.
  They can be implemented as state automaton with stack. This stack is used to represent the nesting level of the syntax. In practice, they're usually implemented as a top-down, recursive-descent parser which uses machine's procedure call stack to track the nesting level, and use recursively called procedures/functions for every non-terminal symbol in their syntax.
  But they can't handle with a context-sensitive syntax. E.g. when you have an expression x+3 and in one context this x could be a name of a variable, and in other context it could be a name of a function etc.

• Level 1: Context-sensitive grammars

• Level 0: Unrestricted grammars
  Also called recursively enumerable grammars.

The only way I can get this to work is to manually instantiate the section handler type, pass the raw XML to it, and cast the resulting object.

Seems pretty inefficient, but there you go.

I wrote an extension method to encapsulate this:

public static class ConfigurationSectionExtensions
{
    public static T GetAs<T>(this ConfigurationSection section)
    {
        var sectionInformation = section.SectionInformation;

        var sectionHandlerType = Type.GetType(sectionInformation.Type);
        if (sectionHandlerType == null)
        {
            throw new InvalidOperationException(string.Format("Unable to find section handler type '{0}'.", sectionInformation.Type));
        }

        IConfigurationSectionHandler sectionHandler;
        try
        {
            sectionHandler = (IConfigurationSectionHandler)Activator.CreateInstance(sectionHandlerType);
        }
        catch (InvalidCastException ex)
        {
            throw new InvalidOperationException(string.Format("Section handler type '{0}' does not implement IConfigurationSectionHandler.", sectionInformation.Type), ex);
        }

        var rawXml = sectionInformation.GetRawXml();
        if (rawXml == null)
        {
            return default(T);
        }

        var xmlDocument = new XmlDocument();
        xmlDocument.LoadXml(rawXml);

        return (T)sectionHandler.Create(null, null, xmlDocument.DocumentElement);
    }
}

The way you would call it in your example is:

var map = new ExeConfigurationFileMap
{
    ExeConfigFilename = @"c:\\foo.config"
};
var configuration = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None);
var myParamsSection = configuration.GetSection("MyParams");
var myParamsCollection = myParamsSection.GetAs<NameValueCollection>();

You are using a wrong url for youtube auto play http://www.youtube.com/embed/JW5meKfy3fY&autoplay=1 this url display youtube id as wholeJW5meKfy3fY&autoplay=1 which youtube rejects to play. we have to pass autoplay variable to youtube, therefore you have to use ? instead of & so your url will be http://www.youtube.com/embed/JW5meKfy3fY?autoplay=1 and your final iframe will be like that.

<iframe src="http://www.youtube.com/embed/xzvScRnF6MU?autoplay=1" width="960" height="447" frameborder="0" allowfullscreen></iframe>

I was also having the same problem. I tried the following and it's working for me now:
Please try the following steps:

Go to..

File > Settings > Appearance & Behavior > System Settings > HTTP Proxy [Under IDE Settings] Enable following option Auto-detect proxy settings

On Mac it's under:

Android Studio > Preferences > Appearance & Behaviour... etc

you can also use the test connection button and check with google.com to see if it works or not.

Warning: untested code.

$dailyData = DB::table('page_views')
    ->select('created_at', DB::raw('count(*) as views'))
    ->groupBy('created_at')
    ->get();

If you want to use position: absolute; on the div with position: relative; on the td you will run into issues. FF, safari, and chrome (mac, not PC though) will not position the div relative to the td (like you would expect) this is also true for divs with display: table-whatever; so if you want to do that you need two divs, one for the container width: 100%; height: 100%; and no border so it fills the td without any visual impact. and then the absolute one.

other than that why not just split the cell?

There is a super() in python also.

Example for how a super class method is called from a sub class method

class Dog(object):
    name = ''
    moves = []

    def __init__(self, name):
        self.name = name

    def moves_setup(self,x):
        self.moves.append('walk')
        self.moves.append('run')
        self.moves.append(x)
    def get_moves(self):
        return self.moves

class Superdog(Dog):

    #Let's try to append new fly ability to our Superdog
    def moves_setup(self):
        #Set default moves by calling method of parent class
        super().moves_setup("hello world")
        self.moves.append('fly')
dog = Superdog('Freddy')
print (dog.name)
dog.moves_setup()
print (dog.get_moves()) 

This example is similar to the one explained above.However there is one difference that super doesn't have any arguments passed to it.This above code is executable in python 3.4 version.

Suppose you have

<body>
  <div id="root" />
</body>

With normal CSS, you can do the following. See a working app https://github.com/onmyway133/Lyrics/blob/master/index.html

#root {
  position: absolute;
  top: 0;
  left: 0;
  height: 100%;
  width: 100%;
}

With flexbox, you can

html, body {
  height: 100%
}
body {
  display: flex;
  align-items: stretch;
}

#root {
  width: 100%
}

First of all, you need to check that the IIS is installed in your machine, for that you can go to:

Control Panel --> Add or Remove Programs --> Windows Features --> And Check if Internet Information Services is installed with at least the 'Web Administration Tools' Enabled and The 'World Wide Web Service'

If not, check it, and Press Accept to install it.

Once that is done, you need to go to Administrative Tools in Control Panel and the IIS Will be there. Or simply run inetmgr (after Win+R).

Edit: You should have something like this:

I developed these 3 useful functions:

def loadModule(moduleName):
    module = None
    try:
        import sys
        del sys.modules[moduleName]
    except BaseException as err:
        pass
    try:
        import importlib
        module = importlib.import_module(moduleName)
    except BaseException as err:
        serr = str(err)
        print("Error to load the module '" + moduleName + "': " + serr)
    return module

def reloadModule(moduleName):
    module = loadModule(moduleName)
    moduleName, modulePath = str(module).replace("' from '", "||").replace("<module '", '').replace("'>", '').split("||")
    if (modulePath.endswith(".pyc")):
        import os
        os.remove(modulePath)
        module = loadModule(moduleName)
    return module

def getInstance(moduleName, param1, param2, param3):
    module = reloadModule(moduleName)
    instance = eval("module." + moduleName + "(param1, param2, param3)")
    return instance

And everytime I want to reload a new instance I just have to call getInstance() like this:

myInstance = getInstance("MyModule", myParam1, myParam2, myParam3)

Finally I can call all the functions inside the new Instance:

myInstance.aFunction()

The only specificity here is to customize the params list (param1, param2, param3) of your instance.

A cleanup of the answer pointed out by David Santamaria:

/**
 * Check to see if a port is available.
 *
 * @param port
 *            the port to check for availability.
 */
public static boolean isPortAvailable(int port) {
    try (var ss = new ServerSocket(port); var ds = new DatagramSocket(port)) {
        return true;
    } catch (IOException e) {
        return false;
    }
}

This is still subject to a race condition pointed out by user207421 in the comments to David Santamaria's answer (something could grab the port after this method closes the ServerSocket and DatagramSocket and returns).

As a newbie in React world, I came across a similar issues where I could not edit the textarea and struggled with binding. It's worth knowing about controlled and uncontrolled elements when it comes to react.

The value of the following uncontrolled textarea cannot be changed because of value

 <textarea type="text" value="some value"
    onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following uncontrolled textarea can be changed because of use of defaultValue or no value attribute

<textarea type="text" defaultValue="sample" 
    onChange={(event) => this.handleOnChange(event)}></textarea>

<textarea type="text" 
   onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following controlled textarea can be changed because of how value is mapped to a state as well as the onChange event listener

<textarea value={this.state.textareaValue} 
onChange={(event) => this.handleOnChange(event)}></textarea>

Here is my solution using different syntax. I prefer the auto-bind than manual binding however, if I were to not use {(event) => this.onXXXX(event)} then that would cause the content of textarea to be not editable OR the event.preventDefault() does not work as expected. Still a lot to learn I suppose.

class Editor extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      textareaValue: ''
    }
  }
  handleOnChange(event) {
    this.setState({
      textareaValue: event.target.value
    })
  }
  handleOnSubmit(event) {
    event.preventDefault();
    this.setState({
      textareaValue: this.state.textareaValue + ' [Saved on ' + (new Date()).toLocaleString() + ']'
    })
  }
  render() {
    return <div>
        <form onSubmit={(event) => this.handleOnSubmit(event)}>
          <textarea rows={10} cols={30} value={this.state.textareaValue} 
            onChange={(event) => this.handleOnChange(event)}></textarea>
          <br/>
          <input type="submit" value="Save"/>
        </form>
      </div>
  }
}
ReactDOM.render(<Editor />, document.getElementById("content"));

The versions of libraries are

"babel-cli": "6.24.1",
"babel-preset-react": "6.24.1"
"React & ReactDOM v15.5.4" 

Without loop:

document.getElementsByName('gender').reduce(function(value, checkable) {
    if(checkable.checked == true) 
        value = checkable.value; 
    return value;
}, '');

reduce is just a function that will feed sequentially array elements to second argument of callback, and previously returned function to value, while for the first run, it will use value of second argument.

The only minus of this approach is that reduce will traverse every element returned by getElementsByName even after it have found selected radio button.

While technically valid, all these jumps obscure control flow -- especially the continue statement.

I would use such a trick as a last resort, not first one.

How about

while (something = get_something())
{
    switch (something)
    {
    case A:
    case B:
        do_something();
    }        
}

It's shorter and perform its stuff in a more clear way.

We have working implementation of Least Common Multiple on Calculla which works for any number of inputs also displaying the steps.

What we do is:

0: Assume we got inputs[] array, filled with integers. So, for example:
   inputsArray = [6, 15, 25, ...]
   lcm = 1

1: Find minimal prime factor for each input.
   Minimal means for 6 it's 2, for 25 it's 5, for 34 it's 17
   minFactorsArray = []

2: Find lowest from minFactors:
   minFactor = MIN(minFactorsArray)

3: lcm *= minFactor

4: Iterate minFactorsArray and if the factor for given input equals minFactor, then divide the input by it:
  for (inIdx in minFactorsArray)
    if minFactorsArray[inIdx] == minFactor
      inputsArray[inIdx] \= minFactor

5: repeat steps 1-4 until there is nothing to factorize anymore. 
   So, until inputsArray contains only 1-s.

And that's it - you got your lcm.

Summary:

• Array need to use:

  • So often as possible. It's fast and takes smallest RAM range for same amount information.
  • If you know exact count of cells needed
  • If data saved in array < 85000 b (85000/32 = 2656 elements for integer data)
  • If needed high Random Access speed

• List need to use:

  • If needed to add cells to the end of list (often)
  • If needed to add cells in the beginning/middle of the list (NOT OFTEN)
  • If data saved in array < 85000 b (85000/32 = 2656 elements for integer data)
  • If needed high Random Access speed

• LinkedList need to use:

  • If needed to add cells in the beginning/middle/end of the list (often)

  • If needed only sequential access (forward/backward)

  • If you need to save LARGE items, but items count is low.

  • Better do not use for large amount of items, as it's use additional memory for links.

    If you not sure that you need LinkedList -- YOU DON'T NEED IT.

On Windows, just check in the windows task manager if there are any other adb processes running.

Or run adb kill-server

If yes, just kill it & then perform the adb start-server command.

I hope, it should solve the problem.

I recently had to do this in R:

inversionNumber <- function(x){
    mergeSort <- function(x){
        if(length(x) == 1){
            inv <- 0
        } else {
            n <- length(x)
            n1 <- ceiling(n/2)
            n2 <- n-n1
            y1 <- mergeSort(x[1:n1])
            y2 <- mergeSort(x[n1+1:n2])
            inv <- y1$inversions + y2$inversions
            x1 <- y1$sortedVector
            x2 <- y2$sortedVector
            i1 <- 1
            i2 <- 1
            while(i1+i2 <= n1+n2+1){
                if(i2 > n2 || i1 <= n1 && x1[i1] <= x2[i2]){
                    x[i1+i2-1] <- x1[i1]
                    i1 <- i1 + 1
                } else {
                    inv <- inv + n1 + 1 - i1
                    x[i1+i2-1] <- x2[i2]
                    i2 <- i2 + 1
                }
            }
        }
        return (list(inversions=inv,sortedVector=x))
    }
    r <- mergeSort(x)
    return (r$inversions)
}

Interesting little problem. It is a bit tricky, since real numbers, not always represent exact integers, even if they are meant to, so it's important to allow a tolerance.

For instance tolerance could be 1E-6, in the unit tests, I kept a rather coarse tolerance to have shorter numbers.

None of the answers that I can read now works in this way, so here is my solution:

public boolean isInteger(double n, double tolerance) {
    double absN = Math.abs(n);
    return Math.abs(absN - Math.round(absN)) <= tolerance;
}

And the unit test, to make sure it works:

@Test
public void checkIsInteger() {
    final double TOLERANCE = 1E-2;
    assertThat(solver.isInteger(1, TOLERANCE), is(true));

    assertThat(solver.isInteger(0.999, TOLERANCE), is(true));
    assertThat(solver.isInteger(0.9, TOLERANCE), is(false));

    assertThat(solver.isInteger(1.001, TOLERANCE), is(true));
    assertThat(solver.isInteger(1.1, TOLERANCE), is(false));

    assertThat(solver.isInteger(-1, TOLERANCE), is(true));

    assertThat(solver.isInteger(-0.999, TOLERANCE), is(true));
    assertThat(solver.isInteger(-0.9, TOLERANCE), is(false));

    assertThat(solver.isInteger(-1.001, TOLERANCE), is(true));        
    assertThat(solver.isInteger(-1.1, TOLERANCE), is(false));
}

To select a value from the dropdown use the index like this:

if we have the

<asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="true"></asp:DropDownList>

you would use :

DropDownList1.Items[DropDownList1.SelectedIndex].Value

this would return the value for the selected index.

I recommend you take a look at the list of editors on Python's wiki, as well as these related questions:

• What IDE to use for Python?
• Which editor/IDE should I use for Python?

From PEP 8 - Style Guide for Python Code:

The preferred way of wrapping long lines is by using Python's implied line continuation inside parentheses, brackets and braces. If necessary, you can add an extra pair of parentheses around an expression, but sometimes using a backslash looks better. Make sure to indent the continued line appropriately.

Example of implicit line continuation:

a = some_function(
    '1' + '2' + '3' - '4')

On the topic of line-breaks around a binary operator, it goes on to say:-

For decades the recommended style was to break after binary operators. But this can hurt readability in two ways: the operators tend to get scattered across different columns on the screen, and each operator is moved away from its operand and onto the previous line.

In Python code, it is permissible to break before or after a binary operator, as long as the convention is consistent locally. For new code Knuth's style (line breaks before the operator) is suggested.

Example of explicit line continuation:

a = '1'   \
    + '2' \
    + '3' \
    - '4'

I would highly recommend that you at least take the time to skim the documentation on any objects you use from the .net framework. While the documentation can be pretty poor at some times it is still invaluable especially when you run into situations like this.

But as James Atkinson said it's simply a matter of adding subitems to a listviewitem like so:

ListViewItem i = new ListViewItem("column1");
i.SubItems.Add("column2");
i.SubItems.Add("column3");

Here's an ES6 version, conversion to vanilla JS shouldn't be too hard but I already have jQuery anyways:

function select(options, selected) {_x000D_
  return Object.entries(options).reduce((r, [k, v]) => r.append($('<option>').val(k).text(v)), $('<select>')).val(selected);_x000D_
}_x000D_
$('body').append(select({'option1': 'label 1', 'option2': 'label 2'}, 'option2'));

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>

Here's a small example to demonstrate this (which only applied to DataFrames, not Series, until Pandas 0.19 where it applies to both):

In [1]: df1 = pd.DataFrame([[1, 2], [3, 4]])

In [2]: df2 = pd.DataFrame([[3, 4], [1, 2]], index=[1, 0])

In [3]: df1 == df2
Exception: Can only compare identically-labeled DataFrame objects

One solution is to sort the index first (Note: some functions require sorted indexes):

In [4]: df2.sort_index(inplace=True)

In [5]: df1 == df2
Out[5]: 
      0     1
0  True  True
1  True  True

Note: == is also sensitive to the order of columns, so you may have to use sort_index(axis=1):

In [11]: df1.sort_index().sort_index(axis=1) == df2.sort_index().sort_index(axis=1)
Out[11]: 
      0     1
0  True  True
1  True  True

Note: This can still raise (if the index/columns aren't identically labelled after sorting).

you can join both tables even on UPDATE statements,

UPDATE  a
SET     a.marks = b.marks
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

• SQLFiddle Demo

for faster performance, define an INDEX on column marks on both tables.

using SUBQUERY

UPDATE  tempDataView 
SET     marks = 
        (
          SELECT marks 
          FROM tempData b 
          WHERE tempDataView.Name = b.Name
        )

You can do the following:

  public class Numbers {
    private int number1 = 50;
    private int number2 = 100;
    private List<Integer> list;

    public Numbers() {
      list = new ArrayList<Integer>();
      list.add(number1);
      list.add(number2);
    }

    int getNumber(int pos)
    {
      return list.get(pos);
    }
  }

  public class Test {
    private Numbers numbers;

    public Test(){
      numbers = new Numbers();
      int number1 = numbers.getNumber(0);
      int number2 = numbers.getNumber(1);
    }
  }

You can use the multi-argument constructors of the URI class. From the URI javadoc:

The multi-argument constructors quote illegal characters as required by the components in which they appear. The percent character ('%') is always quoted by these constructors. Any other characters are preserved.

So if you use

URI uri = new URI("http", "www.google.com?q=a b");

Then you get http:www.google.com?q=a%20b which isn't quite right, but it's a little closer.

If you know that your string will not have URL fragments (e.g. http://example.com/page#anchor), then you can use the following code to get what you want:

String s = "http://www.google.com?q=a b";
String[] parts = s.split(":",2);
URI uri = new URI(parts[0], parts[1], null);

To be safe, you should scan the string for # characters, but this should get you started.

On which point does HTTPURLConnection try to establish a connection to the given URL?

It's worth clarifying, there's the 'UrlConnection' instance and then there's the underlying Tcp/Ip/SSL socket connection, 2 different concepts. The 'UrlConnection' or 'HttpUrlConnection' instance is synonymous with a single HTTP page request, and is created when you call url.openConnection(). But if you do multiple url.openConnection()'s from the one 'url' instance then if you're lucky, they'll reuse the same Tcp/Ip socket and SSL handshaking stuff...which is good if you're doing lots of page requests to the same server, especially good if you're using SSL where the overhead of establishing the socket is very high.

See: HttpURLConnection implementation

You can use COALESCE:

SELECT  orderhed.ordernum, 
    orderhed.orderdate, 
    currrate.currencycode,  
    coalesce(currrate.currentrate, 1) as currentrate
FROM orderhed 
LEFT OUTER JOIN currrate 
    ON orderhed.company = currrate.company 
    AND orderhed.orderdate = currrate.effectivedate

Or even IsNull():

SELECT  orderhed.ordernum, 
    orderhed.orderdate, 
    currrate.currencycode,  
    IsNull(currrate.currentrate, 1) as currentrate
FROM orderhed 
LEFT OUTER JOIN currrate 
    ON orderhed.company = currrate.company 
    AND orderhed.orderdate = currrate.effectivedate

Here is an article to help decide between COALESCE and IsNull:

http://www.mssqltips.com/sqlservertip/2689/deciding-between-coalesce-and-isnull-in-sql-server/

Add this to you PageLoad and it will solve your problem:

ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);
scriptManager.RegisterPostBackControl(this.lblbtndoc1);

To resolve external dependencies within project. below things are important..
1. The compiler should know that where are header '.h' files located in workspace.
2. The linker able to find all specified  all '.lib' files & there names for current project.

So, Developer has to specify external dependencies for Project as below..

1. Select Project in Solution explorer.

2 . Project Properties -> Configuration Properties -> C/C++ -> General
specify all header files in "Additional Include Directories".

3.  Project Properties -> Configuration Properties -> Linker -> General
specify relative path for all lib files in "Additional Library Directories".

you can use

^[\w.-]+$

the + is to make sure it has at least 1 character. Need the ^ and $ to denote the begin and end, otherwise if the string has a match in the middle, such as @@@@xyz%%%% then it is still a match.

\w already includes alphabets (upper and lower case), numbers, and underscore. So the rest ., -, are just put into the "class" to match. The + means 1 occurrence or more.

P.S. thanks for the note in the comment

nobody answered the question about whether you should implement IDisposable even though you dont need it.

Short answer : No

Long answer:

This would allow a consumer of your class to use 'using'. The question I would ask is - why would they do it? Most devs will not use 'using' unless they know that they must - and how do they know. Either

• its obviuos the them from experience (a socket class for example)
• its documented
• they are cautious and can see that the class implements IDisposable

So by implementing IDisposable you are telling devs (at least some) that this class wraps up something that must be released. They will use 'using' - but there are other cases where using is not possible (the scope of object is not local); and they will have to start worrying about the lifetime of the objects in those other cases - I would worry for sure. But this is not necessary

You implement Idisposable to enable them to use using, but they wont use using unless you tell them to.

So dont do it

To provide POST parameter send your parameter as JSONObject in to the JsonObjectRequest constructor. 3rd parameter accepts a JSONObject that is used in Request body.

JSONObject paramJson = new JSONObject();

paramJson.put("key1", "value1");
paramJson.put("key2", "value2");


JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST,url,paramJson,
    new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {

        }
    },
    new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    });
requestQueue.add(jsonObjectRequest);

You may like to try something like this which covers all the bases, including not relying on whitespace after the number:

>>> import re
>>> numeric_const_pattern = r"""
...     [-+]? # optional sign
...     (?:
...         (?: \d* \. \d+ ) # .1 .12 .123 etc 9.1 etc 98.1 etc
...         |
...         (?: \d+ \.? ) # 1. 12. 123. etc 1 12 123 etc
...     )
...     # followed by optional exponent part if desired
...     (?: [Ee] [+-]? \d+ ) ?
...     """
>>> rx = re.compile(numeric_const_pattern, re.VERBOSE)
>>> rx.findall(".1 .12 9.1 98.1 1. 12. 1 12")
['.1', '.12', '9.1', '98.1', '1.', '12.', '1', '12']
>>> rx.findall("-1 +1 2e9 +2E+09 -2e-9")
['-1', '+1', '2e9', '+2E+09', '-2e-9']
>>> rx.findall("current level: -2.03e+99db")
['-2.03e+99']
>>>

For easy copy-pasting:

numeric_const_pattern = '[-+]? (?: (?: \d* \. \d+ ) | (?: \d+ \.? ) )(?: [Ee] [+-]? \d+ ) ?'
rx = re.compile(numeric_const_pattern, re.VERBOSE)
rx.findall("Some example: Jr. it. was .23 between 2.3 and 42.31 seconds")

I literally deleted every file from c:\xampp\mysql\data\ except my.ini and it works

Put very simply, request timeout means there was no response whereas destination unreachable may mean the address specified does not exist i.e. you typed in the wrong IP address.

This is an older post, but I do have a better solution. Create a form containing all of your post values as hidden fields and give the form a name such as:

<form name="RefreshForm" method="post" action="http://yoursite/yourscript">
    <input type="hidden" name="postVariable" value="PostData">
</form>

Then all you need to do in your setTimeout is RefreshForm.submit();

Cheers!

This is an interesting question and since it isn't explained very explicitly in the documentation I'll answer this by going through the sourcecode of mod_rewrite; demonstrating a big benefit of open-source.

In the top section you'll quickly spot the defines used to name these flags:

#define CONDFLAG_NONE               1<<0
#define CONDFLAG_NOCASE             1<<1
#define CONDFLAG_NOTMATCH           1<<2
#define CONDFLAG_ORNEXT             1<<3
#define CONDFLAG_NOVARY             1<<4

and searching for CONDFLAG_ORNEXT confirms that it is used based on the existence of the [OR] flag:

else if (   strcasecmp(key, "ornext") == 0
         || strcasecmp(key, "OR") == 0    ) {
    cfg->flags |= CONDFLAG_ORNEXT;
}

The next occurrence of the flag is the actual implementation where you'll find the loop that goes through all the RewriteConditions a RewriteRule has, and what it basically does is (stripped, comments added for clarity):

# loop through all Conditions that precede this Rule
for (i = 0; i < rewriteconds->nelts; ++i) {
    rewritecond_entry *c = &conds[i];

    # execute the current Condition, see if it matches
    rc = apply_rewrite_cond(c, ctx);

    # does this Condition have an 'OR' flag?
    if (c->flags & CONDFLAG_ORNEXT) {
        if (!rc) {
            /* One condition is false, but another can be still true. */
            continue;
        }
        else {
            /* skip the rest of the chained OR conditions */
            while (   i < rewriteconds->nelts
                   && c->flags & CONDFLAG_ORNEXT) {
                c = &conds[++i];
            }
        }
    }
    else if (!rc) {
        return 0;
    }
}

You should be able to interpret this; it means that OR has a higher precedence, and your example indeed leads to if ( (A OR B) AND (C OR D) ). If you would, for example, have these Conditions:

RewriteCond A [or]
RewriteCond B [or]
RewriteCond C
RewriteCond D

it would be interpreted as if ( (A OR B OR C) and D ).

if you want that not contains any of a-z and A-Z:

SELECT * FROM mytable WHERE NOT REGEXP_LIKE(column_1, '[A-Za-z]')

something like:

"98763045098" or "!%436%$7%$*#"

or other languages like persian, arabic and ... like this:

"???? ????"

static String  string_swap(String str, int x, int y)
{

    if( x < 0 || x >= str.length() || y < 0 || y >= str.length())
    return "Invalid index";

    char arr[] = str.toCharArray();
    char tmp = arr[x];
    arr[x] = arr[y];
    arr[y] = tmp;

    return new String(arr);
}

Although os.rename() and shutil.move() will both rename files, the command that is closest to the Unix mv command is shutil.move(). The difference is that os.rename() doesn't work if the source and destination are on different disks, while shutil.move() doesn't care what disk the files are on.

Okay, I have refined my regular expression based on the solution you came up with (which erroneously matches strings that start with 'test').

^((?!foo).)*$

This regular expression will match only strings that do not contain foo. The first lookahead will deny strings beginning with 'foo', and the second will make sure that foo isn't found elsewhere in the string.

You will probably get an UAC prompt when importing the reg file. If you accept that, you have more rights.

Since you are writing to the 'policies' key, you need to have elevated rights. This part of the registry protected, because it contains settings that are administered by your system administrator.

Alternatively, you may try to run regedit.exe from the command prompt.

regedit.exe /S yourfile.reg

.. should silently import the reg file. See RegEdit Command Line Options Syntax for more command line options.

A bin file is just the bits and bytes that go into the rom or a particular address from which you will run the program. You can take this data and load it directly as is, you need to know what the base address is though as that is normally not in there.

An elf file contains the bin information but it is surrounded by lots of other information, possible debug info, symbols, can distinguish code from data within the binary. Allows for more than one chunk of binary data (when you dump one of these to a bin you get one big bin file with fill data to pad it to the next block). Tells you how much binary you have and how much bss data is there that wants to be initialised to zeros (gnu tools have problems creating bin files correctly).

The elf file format is a standard, arm publishes its enhancements/variations on the standard. I recommend everyone writes an elf parsing program to understand what is in there, dont bother with a library, it is quite simple to just use the information and structures in the spec. Helps to overcome gnu problems in general creating .bin files as well as debugging linker scripts and other things that can help to mess up your bin or elf output.

And to add on to the already solved problem, I had installed Portable Scientific Python on my flash drive E: which on another computer changed to D:, I would get the error "The system cannot find the file specified". So I used parent directory to define the path, like this:

From this:

{
    "cmd": ["E:/WPy64-3720/python-3.7.2.amd64/python.exe", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

To this:

{
    "cmd": ["../../../../WPy64-3720/python-3.7.2.amd64/python.exe","$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

You can modify depending on where your python is installed your python.

I fixed this by adding another div in the one that overflows. Then you compare the heights of the 2 divs.

<div class="AAAA overflow-hidden" style="height: 20px;" >
    <div class="BBBB" >
        Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
    </div>
</div>

and the js

    if ($('.AAAA').height() < $('.BBBB').height()) {
        console.log('we have overflow')
    } else {
        console.log('NO overflow')
    }

This looks easier...

Another variant here we have circular range connecting head to toe and accepts only min value to given input. This had helped me get char code values for one of the encryption algorithm.

function closestNumberInCircularRange(codes, charCode) {
  return codes.reduce((p_code, c_code)=>{
    if(((Math.abs(p_code-charCode) > Math.abs(c_code-charCode)) || p_code > charCode) && c_code < charCode){
      return c_code;
    }else if(p_code < charCode){
      return p_code;
    }else if(p_code > charCode && c_code > charCode){
      return Math.max.apply(Math, [p_code, c_code]);
    }
    return p_code;
  });
}

As an alternative, if you don't want to create config files, do the unattended upload with curl instead of ftp:

curl -u user:password -T file ftp://server/dir/file

You can have just one ng-view.

You can change its content in several ways: ng-include, ng-switch or mapping different controllers and templates through the routeProvider.

There should not be a space after name.

After beating my head on this for at least an hour, I offer this answer to try to expand on the comments some others have made. To ignore a folder/directory, do the following: if you don't have a .gitignore file in the root of your project (that name exactly ".gitignore"), create a dummy text file in the folder you want to exclude. Inside of Source Tree, right click on it and select Ignore. You'll get a popup that looks like this.

Select "Everything underneath" and select the folder you want to ignore from the drop-down list. This will create a .gitignore file in your root directory and put the folder specification in it.

If you do have a .gitignore folder already in your root folder, you could follow the same approach above, or you can just edit the .gitignore file and add the folder you want to exclude. It's just a text file. Note that it uses forward slashes in path names rather than backslashes, as we Windows users are accustomed to. I tried creating a .gitignore text file by hand in Windows Explorer, but it didn't let me create a file without a name (i.e. with only the extension).

Note that adding the .gitignore and the file specification will have no effect on files that are already being tracked. If you're already tracking these, you'll have to stop tracking them. (Right-click on the folder or file and select Stop Tracking.) You'll then see them change from having a green/clean or amber/changed icon to a red/removed icon. On your next commit the files will be removed from the repository and thereafter appear with a blue/ignored icon. Another contributor asked why Ignore was disabled for particular files and I believe it was because he was trying to ignore a file that was already being tracked. You can only ignore a file that has a blue question mark icon.

Add this in your CSS code and change the red background-color with a color of your choice:

.dropdown-menu>.active>a {color:black; background-color:red;}
.dropdown-menu>.active>a:focus {color:black; background-color:red;}
.dropdown-menu>.active>a:hover {color:black; background-color:red;}

I asked the same question to Xamarin support team, they replied with following:

You can develop an app with Xamarin for commercial usage - there is no extra charge! We only require you to comply with Visual Studio's licensing terms,

which means that in companies of less than 250 employees with less than $1million USD annual revenue, you may use Visual Studio completely free (including Xamarin) for up to 5 developers.

However after you pass those barriers, you would need a Visual Studio license (which includes Xamarin).

Refer the screenshot below.

With Java 8+, you can use the new Java time API:

• to parse the time:

  LocalTime time = LocalTime.parse("11:22")
  

• to do date comparisons, you have LocalTime::isBefore and LocalTime::isAfter - note that these methods are strict

So you problem would be as simple as:

public static void main(String[] args) {
  LocalTime time = LocalTime.parse("11:22");
  System.out.println(isBetween(time, LocalTime.of(10, 0), LocalTime.of(18, 0)));
}

public static boolean isBetween(LocalTime candidate, LocalTime start, LocalTime end) {
  return !candidate.isBefore(start) && !candidate.isAfter(end);  // Inclusive.
}

For inclusive beginning but exclusive ending (half-open), use this line.

return !candidate.isBefore(start) && candidate.isBefore(end);  // Exclusive of end.

I had the same issue. turns out that Capitalizing the "A" in "App" was the issue. Also, if you do export: export default App; make sure you export the same name "App" as well.

As you have found out there is no such thing as a single "local IP address". Here's how to find out the local address that can be sent out to a specific host.

1. Create a UDP socket
2. Connect the socket to an outside address (the host that will eventually receive the local address)
3. Use getsockname to get the local address

Because the join() method is in the string class, instead of the list class?

I agree it looks funny.

See http://www.faqs.org/docs/diveintopython/odbchelper_join.html:

Historical note. When I first learned Python, I expected join to be a method of a list, which would take the delimiter as an argument. Lots of people feel the same way, and there’s a story behind the join method. Prior to Python 1.6, strings didn’t have all these useful methods. There was a separate string module which contained all the string functions; each function took a string as its first argument. The functions were deemed important enough to put onto the strings themselves, which made sense for functions like lower, upper, and split. But many hard-core Python programmers objected to the new join method, arguing that it should be a method of the list instead, or that it shouldn’t move at all but simply stay a part of the old string module (which still has lots of useful stuff in it). I use the new join method exclusively, but you will see code written either way, and if it really bothers you, you can use the old string.join function instead.

Haven't used it yet, but looks good though.

I have used the following:

 int index = vpPager.getCurrentItem();
 MyPagerAdapter adapter = ((MyPagerAdapter)vpPager.getAdapter());
 MyFragment suraVersesFragment = (MyFragment)adapter.getRegisteredFragment(index);

select add_months(trunc(sysdate,'MM'),1) -  trunc(sysdate,'MM') from dual;

Note however:

If you issue SET TRANSACTION ISOLATION LEVEL in a stored procedure or trigger, when the object returns control the isolation level is reset to the level in effect when the object was invoked. For example, if you set REPEATABLE READ in a batch, and the batch then calls a stored procedure that sets the isolation level to SERIALIZABLE, the isolation level setting reverts to REPEATABLE READ when the stored procedure returns control to the batch.

Just getting the name from scm.branches is not enough if you've used a build parameter as a branch specifier, e.g. ${BRANCH}. You need to expand that string into a real name:

scm.branches.first().getExpandedName(env.getEnvironment())

Note that getEnvironment() must be an explicit getter otherwise env will look up for an environment variable called environment.

Don't forget that you need to approve those methods to make them accessible from the sandbox.

What happened for me when this was an issue, was that the site had used too much memory, so I'm guessing that it couldn't write to an error log or displayed the error. For clarity, it was a Wordpress site that did this. Upping the memory limit on the server showed the site again.

Use where with a != operator in combination with whereNull

Code::where('to_be_used_by_user_id', '!=' , 2)->orWhereNull('to_be_used_by_user_id')->get()

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

import java.lang.String;

This is an unnecessary import. java.lang classes are always implicitly imported. This means that you do not have to import them manually (explicitly).

protected void onCreate(Bundle savedInstanceState) { /* * Your OnCreate */ Intent intent = getIntent(); String action = intent.getAction(); String type = intent.getType();

//VIEW"
if (Intent.ACTION_VIEW.equals(action) && type != null) {viewhekper(intent);//Handle text being sent}

You don't have to repeat those format identifiers . For yyyy you just need to have Y, etc.

gmdate('Y-m-d h:i:s \G\M\T', time());

In fact you don't even need to give it a default time if you want current time

gmdate('Y-m-d h:i:s \G\M\T');  // This is fine for your purpose

Manual

You can get that list of identifiers Here

As recommended by W3.org, you can use the rel attribute to achieve this.

Example:

<head>
<link rel="icon" 
      type="image/png" 
      href="http://example.com/myicon.png">
...

If your trying to do this with text in a select box or if those two arent working try this one instead:

$.fn.textWidth = function(){
 var calc = '<span style="display:none">' + $(this).text() + '</span>';
 $('body').append(calc);
 var width = $('body').find('span:last').width();
 $('body').find('span:last').remove();
 return width;
};

or

function textWidth(text){
 var calc = '<span style="display:none">' + text + '</span>';
 $('body').append(calc);
 var width = $('body').find('span:last').width();
 $('body').find('span:last').remove();
 return width;
};

if you want to grab the text first

Or see cut_number from the ggplot2 package, e.g.

das$wt_2 <- as.numeric(cut_number(das$wt,3))

Note that cut(...,3) divides the range of the original data into three ranges of equal lengths; it doesn't necessarily result in the same number of observations per group if the data are unevenly distributed (you can replicate what cut_number does by using quantile appropriately, but it's a nice convenience function). On the other hand, Hmisc::cut2() using the g= argument does split by quantiles, so is more or less equivalent to ggplot2::cut_number. I might have thought that something like cut_number would have made its way into dplyr by so far, but as far as I can tell it hasn't.

SET IDENTITY_INSERT tableA ON

You have to make a column list for your INSERT statement:

INSERT Into tableA ([id], [c2], [c3], [c4], [c5] ) 
SELECT [id], [c2], [c3], [c4], [c5] FROM tableB

not like "INSERT Into tableA SELECT ........"

SET IDENTITY_INSERT tableA OFF

Here's the Scalatest page on using the runner and the extended discussion on the -t and -z options.

This post shows what commands work for a test file that uses FunSpec.

Here's the test file:

package com.github.mrpowers.scalatest.example

import org.scalatest.FunSpec

class CardiBSpec extends FunSpec {

  describe("realName") {

    it("returns her birth name") {
      assert(CardiB.realName() === "Belcalis Almanzar")
    }

  }

  describe("iLike") {

    it("works with a single argument") {
      assert(CardiB.iLike("dollars") === "I like dollars")
    }

    it("works with multiple arguments") {
      assert(CardiB.iLike("dollars", "diamonds") === "I like dollars, diamonds")
    }

    it("throws an error if an integer argument is supplied") {
      assertThrows[java.lang.IllegalArgumentException]{
        CardiB.iLike()
      }
    }

    it("does not compile with integer arguments") {
      assertDoesNotCompile("""CardiB.iLike(1, 2, 3)""")
    }

  }

}

This command runs the four tests in the iLike describe block (from the SBT command line):

testOnly *CardiBSpec -- -z iLike

You can also use quotation marks, so this will also work:

testOnly *CardiBSpec -- -z "iLike"

This will run a single test:

testOnly *CardiBSpec -- -z "works with multiple arguments"

This will run the two tests that start with "works with":

testOnly *CardiBSpec -- -z "works with"

I can't get the -t option to run any tests in the CardiBSpec file. This command doesn't run any tests:

testOnly *CardiBSpec -- -t "works with multiple arguments"

Looks like the -t option works when tests aren't nested in describe blocks. Let's take a look at another test file:

class CalculatorSpec extends FunSpec {
  it("adds two numbers") {
    assert(Calculator.addNumbers(3, 4) === 7)
  }
}

-t can be used to run the single test:

testOnly *CalculatorSpec -- -t "adds two numbers"

-z can also be used to run the single test:

testOnly *CalculatorSpec -- -z "adds two numbers"

See this repo if you'd like to run these examples. You can find more info on running tests here.

C language leaves compiler some freedom about the location of the structural elements in the memory:

• memory holes may appear between any two components, and after the last component. It was due to the fact that certain types of objects on the target computer may be limited by the boundaries of addressing
• "memory holes" size included in the result of sizeof operator. The sizeof only doesn't include size of the flexible array, which is available in C/C++
• Some implementations of the language allow you to control the memory layout of structures through the pragma and compiler options

The C language provides some assurance to the programmer of the elements layout in the structure:

• compilers required to assign a sequence of components increasing memory addresses
• Address of the first component coincides with the start address of the structure
• unnamed bit fields may be included in the structure to the required address alignments of adjacent elements

Problems related to the elements alignment:

• Different computers line the edges of objects in different ways
• Different restrictions on the width of the bit field
• Computers differ on how to store the bytes in a word (Intel 80x86 and Motorola 68000)

How alignment works:

• The volume occupied by the structure is calculated as the size of the aligned single element of an array of such structures. The structure should end so that the first element of the next following structure does not the violate requirements of alignment

p.s More detailed info are available here: "Samuel P.Harbison, Guy L.Steele C A Reference, (5.6.2 - 5.6.7)"

Most likely as others have said you want to attach it to your Intent with putExtra. But I want to throw out there that depending on what your use case is, it may be better to have one activity that switches between two fragments. The data is stored in the activity and never has to be passed.

If when running react-native run-android command the second line of the trace is

JS server not recognized, continuing with build...

it means packager for the app cannot be started and the app will fail to load without some extra steps. Note that the end of the trace still reports success:

BUILD SUCCESSFUL

The problem is probably some port conflict (in my case it was the default IIS site that I completely forgot about). Another manifestation of the problem would be a failure to open http://localhost:8081/debugger-ui URL in Chrome.

Once the port conflict is resolved the trace will report

Starting JS server...

then an additional Node window will open (node ...cli.js start) and the app will load/reload successfully.

After that you should be able to open debug console in Chrome with http://localhost:8081/debugger-ui.

There Are 2 ways to return a string from the controller to the view:

First

You could return only the string, but it will not be included in your .cshtml file. it will be just a string appearing in your browser.

Second

You could return a string as the Model object of View Result.

Here is the code sample to do this:

public class HomeController : Controller
{
    // GET: Home
    // this will return just a string, not html
    public string index()
    {
        return "URL to show";
    }

    public ViewResult AutoProperty()
    {   
        string s = "this is a string ";
        // name of view , object you will pass
        return View("Result", s);

    }
}

In the view file to run AutoProperty, It will redirect you to the Result view and will send s
code to the view

<!--this will make this file accept string as it's model-->
@model string

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Result</title>
</head>
<body>
    <!--this will represent the string -->
    @Model
</body>
</html>

I run this at http://localhost:60227/Home/AutoProperty.

You can create a hidden textbox with a value of 0. Put the onLoad() code in a if block that checks to make sure the hidden text box value is 0. if it is execute the code and set the textbox value to 1.

DateTime.Today as it implies is todays date and you need to get the Date a day before so you subtract one day using AddDays(-1);

There are sufficient options available in DateTime to get the formatting like ToShortDateString depending on your culture and you have no need to concatenate them individually.

Also you can have a desirable format in the .ToString() version of the DateTime instance

This simple thing worked for me!

If it says it can't do 2 things at same time, separate them.

git branch branch_name origin/branch_name 

git checkout branch_name

Before actually answering your question:

Parameters in a URL (e.g. key=listOfUsers/user1) are GET parameters and you shouldn't be using them for POST requests. A quick explanation of the difference between GET and POST can be found here.

In your case, to make use of REST principles, you should probably have:

http://ip:5000/users
http://ip:5000/users/<user_id>

Then, on each URL, you can define the behaviour of different HTTP methods (GET, POST, PUT, DELETE). For example, on /users/<user_id>, you want the following:

GET /users/<user_id> - return the information for <user_id>
POST /users/<user_id> - modify/update the information for <user_id> by providing the data
PUT - I will omit this for now as it is similar enough to `POST` at this level of depth
DELETE /users/<user_id> - delete user with ID <user_id> 

So, in your example, you want do a POST to /users/user_1 with the POST data being "John". Then the XPath expression or whatever other way you want to access your data should be hidden from the user and not tightly couple to the URL. This way, if you decide to change the way you store and access data, instead of all your URL's changing, you will simply have to change the code on the server-side.

Now, the answer to your question: Below is a basic semi-pseudocode of how you can achieve what I mentioned above:

from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE'])
def user(user_id):
    if request.method == 'GET':
        """return the information for <user_id>"""
        .
        .
        .
    if request.method == 'POST':
        """modify/update the information for <user_id>"""
        # you can use <user_id>, which is a str but could
        # changed to be int or whatever you want, along
        # with your lxml knowledge to make the required
        # changes
        data = request.form # a multidict containing POST data
        .
        .
        .
    if request.method == 'DELETE':
        """delete user with ID <user_id>"""
        .
        .
        .
    else:
        # POST Error 405 Method Not Allowed
        .
        .
        .

There are a lot of other things to consider like the POST request content-type but I think what I've said so far should be a reasonable starting point. I know I haven't directly answered the exact question you were asking but I hope this helps you. I will make some edits/additions later as well.

Thanks and I hope this is helpful. Please do let me know if I have gotten something wrong.

I had this other answer but this one, based on Jack's answer, is significantly faster might be preferred since it works asynchronously, although slightly slower.

public static class StringExtensionMethods
{
    public static IEnumerable<string> GetLines(this string str, bool removeEmptyLines = false)
    {
        using (var sr = new StringReader(str))
        {
            string line;
            while ((line = sr.ReadLine()) != null)
            {
                if (removeEmptyLines && String.IsNullOrWhiteSpace(line))
                {
                    continue;
                }
                yield return line;
            }
        }
    }
}

Usage:

input.GetLines()      // keeps empty lines

input.GetLines(true)  // removes empty lines

Test:

Action<Action> measure = (Action func) =>
{
    var start = DateTime.Now;
    for (int i = 0; i < 100000; i++)
    {
        func();
    }
    var duration = DateTime.Now - start;
    Console.WriteLine(duration);
};

var input = "";
for (int i = 0; i < 100; i++)
{
    input += "1 \r2\r\n3\n4\n\r5 \r\n\r\n 6\r7\r 8\r\n";
}

measure(() =>
    input.Split(new[] { "\r\n", "\r", "\n" }, StringSplitOptions.None)
);

measure(() =>
    input.GetLines()
);

measure(() =>
    input.GetLines().ToList()
);

Output:

00:00:00.0029996

00:00:04.8221971

Either use the style attribute to add CSS inline on your divs, e.g.:

<div style="color:red"> ... </div>

... or create your own style sheet and reference it after the existing stylesheet then your style sheet should take precedence.

... or add a <style> element in the <head> of your HTML with the CSS you need, this will take precedence over an external style sheet.

You can also add !important after your style values to override other styles on the same element.

Update

Use one of my suggestions above and target the span of class style21, rather than the containing div. The style you are applying on the containing div will not be inherited by the span as it's color is set in the style sheet.

You need to download the java-openjfx package from the official Arch Linux repos. (Also, make sure you have the openjdk8-openjdk package). After doing that, open your project in Intellij and go to Project-Structure -> SDKs -> 1.8 -> Classpath and try removing the old JDK you had and clicking on the directory for the new JDK that will now contain jfxrt.jar.

This is a simple one line way to do it:

    try {
        URL url = new URL("http://....");
        Bitmap image = BitmapFactory.decodeStream(url.openConnection().getInputStream());
    } catch(IOException e) {
        System.out.println(e);
    }

The changed value will be in event.target.value

const app = new Vue({_x000D_
  el: "#app",_x000D_
  data: function() {_x000D_
    return {_x000D_
      message: "Vue"_x000D_
    }_x000D_
  },_x000D_
  methods: {_x000D_
    onChange(event) {_x000D_
      console.log(event.target.value);_x000D_
    }_x000D_
  }_x000D_
})

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue.js"></script>_x000D_
<div id="app">_x000D_
  <select name="LeaveType" @change="onChange" class="form-control">_x000D_
   <option value="1">Annual Leave/ Off-Day</option>_x000D_
   <option value="2">On Demand Leave</option>_x000D_
</select>_x000D_
</div>

I would suggest to use ExpectedConditions and alertIsPresent(). ExpectedConditions is a wrapper class that implements useful conditions defined in ExpectedCondition interface.

public boolean isAlertPresent(){
    boolean foundAlert = false;
    WebDriverWait wait = new WebDriverWait(driver, 0 /*timeout in seconds*/);
    try {
        wait.until(ExpectedConditions.alertIsPresent());
        foundAlert = true;
    } catch (TimeoutException eTO) {
        foundAlert = false;
    }
    return foundAlert;
}

Note: this is based on the answer by nilesh, but adapted to catch the TimeoutException which is thrown by the wait.until() method.

You do

printf ("Hi %s,</br />", $name);

before setting the cookies, which isn't allowed. You can't send any output before the headers, not even a blank line.

I would suggest editing the /etc/default/jenkins

vi /etc/default/jenkins

And changing the $JENKINS_HOME variable (around line 23) to

JENKINS_HOME=/home/jenkins

Then restart the Jenkins with usual

/etc/init.d/jenkins start

Cheers!

Below command will list the content of a jar file.

command :- unzip -l jarfilename.jar.

sample o/p :-

Archive: hello-world.jar Length Date Time Name --------- ---------- ----- ---- 43161 10-18-2017 15:44 hello-world/com/ami/so/search/So.class 20531 10-18-2017 15:44 hello-world/com/ami/so/util/SoUtil.class --------- ------- 63692 2 files

According to manual of unzip

-l list archive files (short format). The names, uncompressed file sizes and modification dates and times of the specified files are printed, along with totals for all files specified. If UnZip was compiled with OS2_EAS defined, the -l option also lists columns for the sizes of stored OS/2 extended attributes (EAs) and OS/2 access control lists (ACLs). In addition, the zipfile comment and individual file comments (if any) are displayed. If a file was archived from a single-case file system (for example, the old MS-DOS FAT file system) and the -L option was given, the filename is converted to lowercase and is prefixed with a caret (^).

I hit this error calling:

dict(my_data)

I fixed this with:

import json

json.loads(my_data)

In a browser like Chrome etc.:

1. Inspect the code (for e.g. in Chrome press ctrl + shift + c);
2. Set overflow: visible on body element (for e.g., <body style="overflow: visible">)
3. Find/Remove any JavaScripts that may routinely be checking for removal of the overflow property:
   • To find such JavaScript code, you could for example, go through the code, or click on different JavaScript code in the code debugger console and hit backspace on your keyboard to remove it.
   • If you're having trouble finding it, you can simply try removing a couple of JavaScripts (you can of course simply press ctrl + z to undo whatever code you delete, or hit refresh to start over).

Good luck!

@Martijn your order of function calls is slightly off. Try this instead:

x=-3:0.1:3;
y = x.^3;
plot(x,y), hold on
plot([-3 3], [0 0], 'k:')
hold off

Open file CSV by Notepad++ . Choose menu Encoding \ Encoding in UTF-8, then fix few cell manuallly.

Then try import again.

Your resource methods won't get hit, so their headers will never get set. The reason is that there is what's called a preflight request before the actual request, which is an OPTIONS request. So the error comes from the fact that the preflight request doesn't produce the necessary headers.

For RESTeasy, you should use CorsFilter. You can see here for some example how to configure it. This filter will handle the preflight request. So you can remove all those headers you have in your resource methods.

here is what you need to install the SQL profiler http://msdn.microsoft.com/en-us/library/bb500441.aspx. However, i would suggest you to read through this one http://blog.sqlauthority.com/2009/08/03/sql-server-introduction-to-sql-server-2008-profiler-2/ if you are looking to do it on your Production Environment. There is another better way to look at the queries watch this one and see if it helps http://www.youtube.com/watch?v=vvziPI5OQyE

If all you are doing is replacing the existing data, then you can do this

std::vector<int> data; // evil global :)

void CopyData(int *newData, size_t count)
{
   data.assign(newData, newData + count);
}

Instead of above way u can achieve the solution simply by following method..

public static void main(String args[]) {
    String ini = "Hi there";
    for (int i = 0; i < ini.length(); i++) {
        System.out.print(" " + ini.charAt(i));
    }
}

List is an interface. Interfaces cannot be instantiated. Only concrete types can be instantiated. You probably want to use an ArrayList, which is an implementation of the List interface.

List<Product> products = new ArrayList<Product>();

Run this command

dotnet --list-sdks

To create a read-only user, you have to setup a different user than the one owning the tables you want to access.

If you just create the user and grant SELECT permission to the read-only user, you'll need to prepend the schema name to each table name. To avoid this, you have basically two options:

1. Set the current schema in your session:

ALTER SESSION SET CURRENT_SCHEMA=XYZ

2. Create synonyms for all tables:

CREATE SYNONYM READER_USER.TABLE1 FOR XYZ.TABLE1

So if you haven't been told the name of the owner schema, you basically have three options. The last one should always work:

1. Query the current schema setting:

SELECT SYS_CONTEXT('USERENV','CURRENT_SCHEMA') FROM DUAL

2. List your synonyms:

SELECT * FROM ALL_SYNONYMS WHERE OWNER = USER

3. Investigate all tables (with the exception of the some well-known standard schemas):

SELECT * FROM ALL_TABLES WHERE OWNER NOT IN ('SYS', 'SYSTEM', 'CTXSYS', 'MDSYS');

In-App Keyboard

This answer tells how to make a custom keyboard to use exclusively within your app. If you want to make a system keyboard that can be used in any app, then see my other answer.

The example will look like this. You can modify it for any keyboard layout.

1. Start a new Android project

I named my project InAppKeyboard. Call yours whatever you want.

2. Add the layout files

Keyboard layout

Add a layout file to res/layout folder. I called mine keyboard. The keyboard will be a custom compound view that we will inflate from this xml layout file. You can use whatever layout you like to arrange the keys, but I am using a LinearLayout. Note the merge tags.

res/layout/keyboard.xml

<merge xmlns:android="http://schemas.android.com/apk/res/android">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

Activity layout

For demonstration purposes our activity has a single EditText and the keyboard is at the bottom. I called my custom keyboard view MyKeyboard. (We will add this code soon so ignore the error for now.) The benefit of putting all of our keyboard code into a single view is that it makes it easy to reuse in another activity or app.

res/layout/activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.inappkeyboard.MainActivity">

    <EditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#c9c9f1"
        android:layout_margin="50dp"
        android:padding="5dp"
        android:layout_alignParentTop="true"/>

    <com.example.inappkeyboard.MyKeyboard
        android:id="@+id/keyboard"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:layout_alignParentBottom="true"/>

</RelativeLayout>

3. Add the Keyboard Java file

Add a new Java file. I called mine MyKeyboard.

The most important thing to note here is that there is no hard link to any EditText or Activity. This makes it easy to plug it into any app or activity that needs it. This custom keyboard view also uses an InputConnection, which mimics the way a system keyboard communicates with an EditText. This is how we avoid the hard links.

MyKeyboard is a compound view that inflates the view layout we defined above.

MyKeyboard.java

public class MyKeyboard extends LinearLayout implements View.OnClickListener {

    // constructors
    public MyKeyboard(Context context) {
        this(context, null, 0);
    }

    public MyKeyboard(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public MyKeyboard(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init(context, attrs);
    }

    // keyboard keys (buttons)
    private Button mButton1;
    private Button mButton2;
    private Button mButton3;
    private Button mButton4;
    private Button mButton5;
    private Button mButton6;
    private Button mButton7;
    private Button mButton8;
    private Button mButton9;
    private Button mButton0;
    private Button mButtonDelete;
    private Button mButtonEnter;

    // This will map the button resource id to the String value that we want to 
    // input when that button is clicked.
    SparseArray<String> keyValues = new SparseArray<>();

    // Our communication link to the EditText
    InputConnection inputConnection;

    private void init(Context context, AttributeSet attrs) {

        // initialize buttons
        LayoutInflater.from(context).inflate(R.layout.keyboard, this, true);
        mButton1 = (Button) findViewById(R.id.button_1);
        mButton2 = (Button) findViewById(R.id.button_2);
        mButton3 = (Button) findViewById(R.id.button_3);
        mButton4 = (Button) findViewById(R.id.button_4);
        mButton5 = (Button) findViewById(R.id.button_5);
        mButton6 = (Button) findViewById(R.id.button_6);
        mButton7 = (Button) findViewById(R.id.button_7);
        mButton8 = (Button) findViewById(R.id.button_8);
        mButton9 = (Button) findViewById(R.id.button_9);
        mButton0 = (Button) findViewById(R.id.button_0);
        mButtonDelete = (Button) findViewById(R.id.button_delete);
        mButtonEnter = (Button) findViewById(R.id.button_enter);

        // set button click listeners
        mButton1.setOnClickListener(this);
        mButton2.setOnClickListener(this);
        mButton3.setOnClickListener(this);
        mButton4.setOnClickListener(this);
        mButton5.setOnClickListener(this);
        mButton6.setOnClickListener(this);
        mButton7.setOnClickListener(this);
        mButton8.setOnClickListener(this);
        mButton9.setOnClickListener(this);
        mButton0.setOnClickListener(this);
        mButtonDelete.setOnClickListener(this);
        mButtonEnter.setOnClickListener(this);

        // map buttons IDs to input strings
        keyValues.put(R.id.button_1, "1");
        keyValues.put(R.id.button_2, "2");
        keyValues.put(R.id.button_3, "3");
        keyValues.put(R.id.button_4, "4");
        keyValues.put(R.id.button_5, "5");
        keyValues.put(R.id.button_6, "6");
        keyValues.put(R.id.button_7, "7");
        keyValues.put(R.id.button_8, "8");
        keyValues.put(R.id.button_9, "9");
        keyValues.put(R.id.button_0, "0");
        keyValues.put(R.id.button_enter, "\n");
    }

    @Override
    public void onClick(View v) {

        // do nothing if the InputConnection has not been set yet
        if (inputConnection == null) return;

        // Delete text or input key value
        // All communication goes through the InputConnection
        if (v.getId() == R.id.button_delete) {
            CharSequence selectedText = inputConnection.getSelectedText(0);
            if (TextUtils.isEmpty(selectedText)) {
                // no selection, so delete previous character
                inputConnection.deleteSurroundingText(1, 0);
            } else {
                // delete the selection
                inputConnection.commitText("", 1);
            }
        } else {
            String value = keyValues.get(v.getId());
            inputConnection.commitText(value, 1);
        }
    }

    // The activity (or some parent or controller) must give us 
    // a reference to the current EditText's InputConnection
    public void setInputConnection(InputConnection ic) {
        this.inputConnection = ic;
    }
}

4. Point the keyboard to the EditText

For system keyboards, Android uses an InputMethodManager to point the keyboard to the focused EditText. In this example, the activity will take its place by providing the link from the EditText to our custom keyboard to.

Since we aren't using the system keyboard, we need to disable it to keep it from popping up when we touch the EditText. Second, we need to get the InputConnection from the EditText and give it to our keyboard.

MainActivity.java

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        EditText editText = (EditText) findViewById(R.id.editText);
        MyKeyboard keyboard = (MyKeyboard) findViewById(R.id.keyboard);

        // prevent system keyboard from appearing when EditText is tapped
        editText.setRawInputType(InputType.TYPE_CLASS_TEXT);
        editText.setTextIsSelectable(true);

        // pass the InputConnection from the EditText to the keyboard
        InputConnection ic = editText.onCreateInputConnection(new EditorInfo());
        keyboard.setInputConnection(ic);
    }
}

If your Activity has multiple EditTexts, then you will need to write code to pass the right EditText's InputConnection to the keyboard. (You can do this by adding an OnFocusChangeListener and OnClickListener to the EditTexts. See this article for a discussion of that.) You may also want to hide or show your keyboard at appropriate times.

Finished

That's it. You should be able to run the example app now and input or delete text as desired. Your next step is to modify everything to fit your own needs. For example, in some of my keyboards I've used TextViews rather than Buttons because it is easier to customize them.

Notes

• In the xml layout file, you could also use a TextView rather a Button if you want to make the keys look better. Then just make the background be a drawable that changes the appearance state when pressed.
• Advanced custom keyboards: For more flexibility in keyboard appearance and keyboard switching, I am now making custom key views that subclass View and custom keyboards that subclass ViewGroup. The keyboard lays out all the keys programmatically. The keys use an interface to communicate with the keyboard (similar to how fragments communicate with an activity). This is not necessary if you only need a single keyboard layout since the xml layout works fine for that. But if you want to see an example of what I have been working on, check out all the Key* and Keyboard* classes here. Note that I also use a container view there whose function it is to swap keyboards in and out.

Instead of trying to serve the node modules folder, you can also use Gulp to copy what you need to wwwroot.

How to do floating point calculations in bash:

Instead of using "here strings" (<<<) with the bc command, like one of the most-upvoted examples does, here's my favorite bc floating point example, right from the EXAMPLES section of the bc man pages (see man bc for the manual pages).

Before we begin, know that an equation for pi is: pi = 4*atan(1). a() below is the bc math function for atan().

1. This is how to store the result of a floating point calculation into a bash variable--in this case into a variable called pi. Note that scale=10 sets the number of decimal digits of precision to 10 in this case. Any decimal digits after this place are truncated.

    pi=$(echo "scale=10; 4*a(1)" | bc -l)
   

2. Now, to have a single line of code that also prints out the value of this variable, simply add the echo command to the end as a follow-up command, as follows. Note the truncation at 10 decimal places, as commanded:

    pi=$(echo "scale=10; 4*a(1)" | bc -l); echo $pi
    3.1415926532
   

3. Finally, let's throw in some rounding. Here we will use the printf function to round to 4 decimal places. Note that the 3.14159... rounds now to 3.1416. Since we are rounding, we no longer need to use scale=10 to truncate to 10 decimal places, so we'll just remove that part. Here's the end solution:

    pi=$(printf %.4f $(echo "4*a(1)" | bc -l)); echo $pi
    3.1416
   

Here's another really great application and demo of the above techniques: measuring and printing run-time.

(See also my other answer here).

Note that dt_min gets rounded from 0.01666666666... to 0.017:

start=$SECONDS; sleep 1; end=$SECONDS; dt_sec=$(( end - start )); dt_min=$(printf %.3f $(echo "$dt_sec/60" | bc -l)); echo "dt_sec = $dt_sec; dt_min = $dt_min"
dt_sec = 1; dt_min = 0.017

You actually don't have access to filesystem (for example reading and writing local files), however, due to HTML5 File Api specification, there are some file properties that you do have access to, and the file size is one of them.

For the HTML below

<input type="file" id="myFile" />

try the following:

//binds to onchange event of your input field
$('#myFile').bind('change', function() {

  //this.files[0].size gets the size of your file.
  alert(this.files[0].size);

});

As it is a part of the HTML5 specification, it will only work for modern browsers (v10 required for IE) and I added here more details and links about other file information you should know: http://felipe.sabino.me/javascript/2012/01/30/javascipt-checking-the-file-size/

Old browsers support

Be aware that old browsers will return a null value for the previous this.files call, so accessing this.files[0] will raise an exception and you should check for File API support before using it

Use the std::vector class from the standard library.

I'm on Ubuntu 20.04 and I kept getting the message that soon I wouldn't be able to login from console. I was terribly confused. Finally, I got to the URL below which will work. But you need to know how to create a PAT (Personal Access Token) which you are going to have to keep in a file on your computer.

Here's what the final URL will look like:

git push https://[email protected]/user-name/repo.git

long PAT (Personal Access Token) value -- The entire long value between the // and the @ sign in the url is your PAT.

user-name will be your exact username

repo.git will be your exact repo name

You need to generate a PAT following the steps at: https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token

That will give you the PAT value that you will place in your URL.

When you create the PAT make sure you choose the following options so it has the ability to allow you to manage your REPOs.

Save Your PAT Or Lose It

Once you have your PAT. You're going to need to save it in a file locally so you can use it again. If you don't save it somewhere there is no way to ever see it again and you'll be forced to create a new PAT

Now you're going to need at the very least :

1. a way to display it in your console so you can see it again.
2. or, A way to copy it to your clipboard automatically.

For 1, just use :

$ cat ~/files/myPatFile.txt

Where the path is a real path to the location and file where you stored your PAT value.

For 2

$ xclip -selection clipboard < ~/files/myPatFile.txt

That'll copy the contents of the file to the clipboard so you can use your PAT more easily.

FYI - if you don't have xclip do the following:

$ sudo apt-get install xclip

Downloads and installs xclip. If you don't have apt-get, you might need to use another installer (like yum)

This is one way to do it:

SQL> set serveroutput on
SQL> CREATE OR REPLACE TYPE MyType AS VARRAY(200) OF VARCHAR2(50);
  2  /

Type created

SQL> CREATE OR REPLACE PROCEDURE testing (t_in MyType) IS
  2  BEGIN
  3    FOR i IN 1..t_in.count LOOP
  4      dbms_output.put_line(t_in(i));
  5    END LOOP;
  6  END;
  7  /

Procedure created

SQL> DECLARE
  2    v_t MyType;
  3  BEGIN
  4    v_t := MyType();
  5    v_t.EXTEND(10);
  6    v_t(1) := 'this is a test';
  7    v_t(2) := 'A second test line';
  8    testing(v_t);
  9  END;
 10  /

this is a test
A second test line

To expand on my comment to @dcp's answer, here's how you could implement the solution proposed there if you wanted to use an associative array:

SQL> CREATE OR REPLACE PACKAGE p IS
  2    TYPE p_type IS TABLE OF VARCHAR2(50) INDEX BY BINARY_INTEGER;
  3  
  4    PROCEDURE pp (inp p_type);
  5  END p;
  6  /

Package created
SQL> CREATE OR REPLACE PACKAGE BODY p IS
  2    PROCEDURE pp (inp p_type) IS
  3    BEGIN
  4      FOR i IN 1..inp.count LOOP
  5        dbms_output.put_line(inp(i));
  6      END LOOP;
  7    END pp;
  8  END p;
  9  /

Package body created
SQL> DECLARE
  2    v_t p.p_type;
  3  BEGIN
  4    v_t(1) := 'this is a test of p';
  5    v_t(2) := 'A second test line for p';
  6    p.pp(v_t);
  7  END;
  8  /

this is a test of p
A second test line for p

PL/SQL procedure successfully completed

SQL> 

This trades creating a standalone Oracle TYPE (which cannot be an associative array) with requiring the definition of a package that can be seen by all in order that the TYPE it defines there can be used by all.

Working with POST in webapi can be tricky! Would like to add to the already correct answer..

Will focus specifically on POST as dealing with GET is trivial. I don't think many would be searching around for resolving an issue with GET with webapis. Anyways..

If your question is - In MVC Web Api, how to- - Use custom action method names other than the generic HTTP verbs? - Perform multiple posts? - Post multiple simple types? - Post complex types via jQuery?

Then the following solutions may help:

First, to use Custom Action Methods in Web API, add a web api route as:

public static void Register(HttpConfiguration config)
{
    config.Routes.MapHttpRoute(
        name: "ActionApi",
        routeTemplate: "api/{controller}/{action}");
}

And then you may create action methods like:

[HttpPost]
public string TestMethod([FromBody]string value)
{
    return "Hello from http post web api controller: " + value;
}

Now, fire the following jQuery from your browser console

$.ajax({
    type: 'POST',
    url: 'http://localhost:33649/api/TestApi/TestMethod',
    data: {'':'hello'},
    contentType: 'application/x-www-form-urlencoded',
    dataType: 'json',
    success: function(data){ console.log(data) }
});

Second, to perform multiple posts, It is simple, create multiple action methods and decorate with the [HttpPost] attrib. Use the [ActionName("MyAction")] to assign custom names, etc. Will come to jQuery in the fourth point below

Third, First of all, posting multiple SIMPLE types in a single action is not possible. Moreover, there is a special format to post even a single simple type (apart from passing the parameter in the query string or REST style). This was the point that had me banging my head with Rest Clients (like Fiddler and Chrome's Advanced REST client extension) and hunting around the web for almost 5 hours when eventually, the following URL proved to be of help. Will quote the relevant content for the link might turn dead!

Content-Type: application/x-www-form-urlencoded
in the request header and add a = before the JSON statement:
={"Name":"Turbo Tina","Email":"[email protected]"}

PS: Noticed the peculiar syntax?

http://forums.asp.net/t/1883467.aspx?The+received+value+is+null+when+I+try+to+Post+to+my+Web+Api

Anyways, let us get over that story. Moving on:

Fourth, posting complex types via jQuery, ofcourse, $.ajax() is going to promptly come in the role:

Let us say the action method accepts a Person object which has an id and a name. So, from javascript:

var person = { PersonId:1, Name:"James" }
$.ajax({
    type: 'POST',
    url: 'http://mydomain/api/TestApi/TestMethod',
    data: JSON.stringify(person),
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    success: function(data){ console.log(data) }
});

And the action will look like:

[HttpPost]
public string TestMethod(Person person)
{
    return "Hello from http post web api controller: " + person.Name;
}

All of the above, worked for me!! Cheers!

A simple solution "workaround" still is to create a class of virtual functions "interface" and inherit it in the caller class. Then pass it as a parameter "could be in the constructor" of the other class that you want to call your caller class back.

DEFINE Interface:

class CallBack 
{
   virtual callMeBack () {};
};

This is the class that you want to call you back:

class AnotherClass ()
{
     public void RegisterMe(CallBack *callback)
     {
         m_callback = callback;
     }

     public void DoSomething ()
     {
        // DO STUFF
        // .....
        // then call
        if (m_callback) m_callback->callMeBack();
     }
     private CallBack *m_callback = NULL;
};

And this is the class that will be called back.

class Caller : public CallBack
{
    void DoSomthing ()
    {
    }

    void callMeBack()
    {
       std::cout << "I got your message" << std::endl;
    }
};

Add & Remove Classes (tested on IE8+)

Add trim() to IE (taken from: .trim() in JavaScript not working in IE)

if(typeof String.prototype.trim !== 'function') {
  String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, ''); 
  }
}

Add and Remove Classes:

function addClass(element,className) {
  var currentClassName = element.getAttribute("class");
  if (typeof currentClassName!== "undefined" && currentClassName) {
    element.setAttribute("class",currentClassName + " "+ className);
  }
  else {
    element.setAttribute("class",className); 
  }
}
function removeClass(element,className) {
  var currentClassName = element.getAttribute("class");
  if (typeof currentClassName!== "undefined" && currentClassName) {

    var class2RemoveIndex = currentClassName.indexOf(className);
    if (class2RemoveIndex != -1) {
        var class2Remove = currentClassName.substr(class2RemoveIndex, className.length);
        var updatedClassName = currentClassName.replace(class2Remove,"").trim();
        element.setAttribute("class",updatedClassName);
    }
  }
  else {
    element.removeAttribute("class");   
  } 
}

Usage:

var targetElement = document.getElementById("myElement");

addClass(targetElement,"someClass");

removeClass(targetElement,"someClass");

A working JSFIDDLE: http://jsfiddle.net/fixit/bac2vuzh/1/

It depends on what runs cron on your system, but all you have to do to run a php script from cron is to do call the location of the php installation followed by the script location. An example with crontab running every hour:

# crontab -e
00 * * * * /usr/local/bin/php /home/path/script.php

On my system, I don't even have to put the path to the php installation:

00 * * * * php /home/path/script.php

On another note, you should not be using mysql extension because it is deprecated, unless you are using an older installation of php. Read here for a comparison.
