Whilst I know that this question is fairly old, but it's a commonly occurring question...

There is both a reason and a distinct need for profanity filters (see Wikipedia entry here), but they often fall short of being 100% accurate for very distinct reasons; Context and accuracy.

It depends (wholly) on what you're trying to achieve - at it's most basic, you're probably trying to cover the "seven dirty words" and then some... Some businesses need to filter the most basic of profanity: basic swear words, URLs or even personal information and so on, but others need to prevent illicit account naming (Xbox live is an example) or far more...

User generated content doesn't just contain potential swear words, it can also contain offensive references to:

• Sexual acts
• Sexual orientation
• Religion
• Ethnicity
• Etc...

And potentially, in multiple languages. Shutterstock has developed basic dirty-words lists in 10 languages to date, but it's still basic and very much oriented towards their 'tagging' needs. There are a number of other lists available on the web.

I agree with the accepted answer that it's not a defined science and as language is a continually evolving challenge but one where a 90% catch rate is better than 0%. It depends purely on your goals - what you're trying to achieve, the level of support you have and how important it is to remove profanities of different types.

In building a filter, you need to consider the following elements and how they relate to your project:

• Words/phrases
• Acronyms (FOAD/LMFAO etc)
• False positives (words, places and names like 'mishit', 'scunthorpe' and 'titsworth')
• URLs (porn sites are an obvious target)
• Personal information (email, address, phone etc - if applicable)
• Language choice (usually English by default)
• Moderation (how, if at all, you can interact with user generated content and what you can do with it)

You can easily build a profanity filter that captures 90%+ of profanities, but you'll never hit 100%. It's just not possible. The closer you want to get to 100%, the harder it becomes... Having built a complex profanity engine in the past that dealt with more than 500K realtime messages per day, I'd offer the following advice:

A basic filter would involve:

• Building a list of applicable profanities
• Developing a method of dealing with derivations of profanities

A moderately complex filer would involve, (In addition to a basic filter):

• Using complex pattern matching to deal with extended derivations (using advanced regex)
• Dealing with Leetspeak (l33t)
• Dealing with false positives

A complex filter would involve a number of the following (In addition to a moderate filter):

• Whitelists and blacklists
• Naive bayesian inference filtering of phrases/terms
• Soundex functions (where a word sounds like another)
• Levenshtein distance
• Stemming
• Human moderators to help guide a filtering engine to learn by example or where matches aren't accurate enough without guidance (a self/continually-improving system)
• Perhaps some form of AI engine

If you rename your Database, MS SQL Server does not rename the underlying files.

Following query gives you the current name of the database and the Logical file name (which might be the original name of the Database when it was created) and also corresponding physical file names.

Note: Un-comment the last line to see only the actual data files

select  db.database_id, 
        db.name "Database Name", 
        files.name "Logical File Name",
        files.physical_name
from    sys.master_files files 
        join sys.databases db on db.database_id = files.database_id 
--                           and files.type_desc = 'ROWS'

I also got the following error when I run a command with PHP, I did the solution like that:

1. From the desktop, right-click the Computer icon.
2. Choose Properties from the context menu.
3. Click the Advanced system settings link.
4. Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New.
5. In the Edit System Variable window, Add C:\xampp\php to your PATH Environment Variable.

Very important note: restart command prompt

Use the length() method in the File class. From the javadocs:

Returns the length of the file denoted by this abstract pathname. The return value is unspecified if this pathname denotes a directory.

UPDATED Nowadays we should use the Files.size() method:

Paths path = Paths.get("/path/to/file");
long size = Files.size(path);

For the second part of the question, straight from File's javadocs:

• getUsableSpace() Returns the number of bytes available to this virtual machine on the partition named by this abstract pathname

• getTotalSpace() Returns the size of the partition named by this abstract pathname

• getFreeSpace() Returns the number of unallocated bytes in the partition named by this abstract path name

I faced the same error, when tried to add colspan to last th

<table>
  <thead>
    <tr>    
      <th>&nbsp;</th> <!-- column 1 -->
      <th colspan="2">&nbsp;</th> <!-- column 2&3 -->
    </tr>
  </thead>

  <tbody>
    <tr>
      <td>&nbsp;</td>
      <td>&nbsp;</td>
      <td>&nbsp;</td>
    </tr>
  </tbody>
</table>

and solved it by adding hidden column to the end of tr

<thead>
  <tr>    
    <th>&nbsp;</th> <!-- column 1 -->
    <th colspan="2">&nbsp;</th> <!-- column 2&3 -->

    <!-- hidden column 4 for proper DataTable applying -->
    <th style="display: none"></th> 
  </tr>
</thead>

<tbody>
  <tr>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>

    <!-- hidden column 4 for proper DataTable applying -->
    <td style="display: none"></td>
  </tr>
</tbody>

Explanaition to that is that for some reason DataTable can't be applied to table with colspan in the last th, but can be applied, if colspan used in any middle th.

This solution is a bit hacky, but simpler and shorter than any other solution I found.

I hope that will help someone.

Recently ran into the same problem, struggled for a bit, found this topic but no answers were correct for me.

My issue was that when I removed main window from my WPF project (it does not have a main window), I forgot to remove StartupUri from App.xaml. I guess this exception can happen if you have a mistake in StartupUri, so in case if anybody is struggling with this - check your StartupUri in App.xaml.

A Step Back

First and foremost, REST describes a URI as a universally unique ID. Far too many people get caught up on the structure of URIs and which URIs are more "restful" than others. This argument is as ludicrous as saying naming someone "Bob" is better than naming him "Joe" – both names get the job of "identifying a person" done. A URI is nothing more than a universally unique name.

So in REST's eyes arguing about whether ?id=["101404","7267261"] is more restful than ?id=101404,7267261 or \Product\101404,7267261 is somewhat futile.

Now, having said that, many times how URIs are constructed can usually serve as a good indicator for other issues in a RESTful service. There are a couple of red flags in your URIs and question in general.

Suggestions

1. Multiple URIs for the same resource and Content-Location

   We may want to accept both styles but does that flexibility actually cause more confusion and head aches (maintainability, documentation, etc.)?

   URIs identify resources. Each resource should have one canonical URI. This does not mean that you can't have two URIs point to the same resource but there are well defined ways to go about doing it. If you do decide to use both the JSON and list based formats (or any other format) you need to decide which of these formats is the main canonical URI. All responses to other URIs that point to the same "resource" should include the Content-Location header.

   Sticking with the name analogy, having multiple URIs is like having nicknames for people. It is perfectly acceptable and often times quite handy, however if I'm using a nickname I still probably want to know their full name – the "official" way to refer to that person. This way when someone mentions someone by their full name, "Nichloas Telsa", I know they are talking about the same person I refer to as "Nick".

2. "Search" in your URI

   A more complex case is when we want to offer more complex inputs. For example, if we want to allow multiple filters on search...

   A general rule of thumb of mine is, if your URI contains a verb, it may be an indication that something is off. URI's identify a resource, however they should not indicate what we're doing to that resource. That's the job of HTTP or in restful terms, our "uniform interface".

   To beat the name analogy dead, using a verb in a URI is like changing someone's name when you want to interact with them. If I'm interacting with Bob, Bob's name doesn't become "BobHi" when I want to say Hi to him. Similarly, when we want to "search" Products, our URI structure shouldn't change from "/Product/..." to "/Search/...".

Answering Your Initial Question

1. Regarding ["101404","7267261"] vs 101404,7267261: My suggestion here is to avoid the JSON syntax for simplicity's sake (i.e. don't require your users do URL encoding when you don't really have to). It will make your API a tad more usable. Better yet, as others have recommended, go with the standard application/x-www-form-urlencoded format as it will probably be most familiar to your end users (e.g. ?id[]=101404&id[]=7267261). It may not be "pretty", but Pretty URIs does not necessary mean Usable URIs. However, to reiterate my initial point though, ultimately when speaking about REST, it doesn't matter. Don't dwell too heavily on it.

2. Your complex search URI example can be solved in very much the same way as your product example. I would recommend going the application/x-www-form-urlencoded format again as it is already a standard that many are familiar with. Also, I would recommend merging the two.

Your URI...

/Search?term=pumas&filters={"productType":["Clothing","Bags"],"color":["Black","Red"]}    

Your URI after being URI encoded...

/Search?term=pumas&filters=%7B%22productType%22%3A%5B%22Clothing%22%2C%22Bags%22%5D%2C%22color%22%3A%5B%22Black%22%2C%22Red%22%5D%7D

Can be transformed to...

/Product?term=pumas&productType[]=Clothing&productType[]=Bags&color[]=Black&color[]=Red

Aside from avoiding the requirement of URL encoding and making things look a bit more standard, it now homogenizes the API a bit. The user knows that if they want to retrieve a Product or List of Products (both are considered a single "resource" in RESTful terms), they are interested in /Product/... URIs.

Adding this just as an addition to @jimt's excellent answer:

one common way to define it all at initialization time is using an anonymous struct:

var opts = []struct {
    shortnm      byte
    longnm, help string
    needArg      bool
}{
    {'a', "multiple", "Usage for a", false},
    {
        shortnm: 'b',
        longnm:  "b-option",
        needArg: false,
        help:    "Usage for b",
    },
}

This is commonly used for testing as well to define few test cases and loop through them.

You need to append your variables to the echoed string. For example:

echo 'This is a string '.$PHPvariable.' and this is more string'; 

From RFC 2616:

HTTP communication usually takes place over TCP/IP connections. The default port is TCP 80, but other ports can be used. This does not preclude HTTP from being implemented on top of any other protocol on the Internet, or on other networks. HTTP only presumes a reliable transport; any protocol that provides such guarantees can be used; the mapping of the HTTP/1.1 request and response structures onto the transport data units of the protocol in question is outside the scope of this specification.

So although it doesn't explicitly say so, UDP is not used because it is not a "reliable transport".

EDIT - more recently, the QUIC protocol (which is more strictly a pseudo-transport or a session layer protocol) does use UDP for carrying HTTP/2.0 traffic and much of Google's traffic already uses this protocol. It's currently progressing towards standardisation as HTTP/3.

You can alter a foreign key constraint with delete cascade option as shown below. This will delete chind table rows related to master table rows when deleted.

ALTER TABLE MasterTable
ADD CONSTRAINT fk_xyz 
FOREIGN KEY (xyz) 
REFERENCES ChildTable (xyz) ON DELETE CASCADE 

if you use general java script and you need to assign string to text area value then

 document.getElementById("textareaid").value='texthere\\\ntexttext'.

you need to replace \n or < br > to \\\n

otherwise it gives Uncaught SyntaxError: Unexpected token ILLEGAL on all browsers.

If you want to filter the models by applicationname and the remaining models by surname:

List<Model> newList = list.Where(m => m.application == "applicationname")
    .Select(m => new Model { 
        application = m.application, 
        users = m.users.Where(u => u.surname == "surname").ToList() 
    }).ToList();

As you can see, it needs to create new models and user-lists, hence it is not the most efficient way.

If you instead don't want to filter the list of users but filter the models by users with at least one user with a given username, use Any:

List<Model> newList = list
    .Where(m => m.application == "applicationname"
            &&  m.users.Any(u => u.surname == "surname"))
    .ToList();

If you still get this error when sending email: "Failed to authenticate on SMTP server with username "[email protected]" using 3 possible authenticators"

You may try one of these methods:

Go to https://accounts.google.com/UnlockCaptcha, click continue and unlock your account for access through other media/sites.

Use double quote for your password: like - "Abc@%$67eSDu"

If the bson extension wasn't the reason, I guessed the other reason for "failed to connect" would be the user id's. So I created a new database and added a user for the database, with a password for that user (note: not mongolab account password). I updated those on my code and voila! It worked. Duh right? :D

Yes there is a major difference between the two methods Use delete_all if you want records to be deleted quickly without model callbacks being called

If you care about your models callbacks then use destroy_all

From the official docs

http://apidock.com/rails/ActiveRecord/Base/destroy_all/class

destroy_all(conditions = nil) public

Destroys the records matching conditions by instantiating each record and calling its destroy method. Each object’s callbacks are executed (including :dependent association options and before_destroy/after_destroy Observer methods). Returns the collection of objects that were destroyed; each will be frozen, to reflect that no changes should be made (since they can’t be persisted).

Note: Instantiation, callback execution, and deletion of each record can be time consuming when you’re removing many records at once. It generates at least one SQL DELETE query per record (or possibly more, to enforce your callbacks). If you want to delete many rows quickly, without concern for their associations or callbacks, use delete_all instead.

and a shortcut:

C:\Windows\System32\cmd.exe /c start shell:AppsFolder\Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge http://localhost:6516

Suppose your "Don't Check" list is on Sheet2 in cells A1:A100, say, and your current client IDs are in Sheet1 in Column A.

What you would do is:

1. Select the whole data table you want conditionally formatted in Sheet1
2. Click Conditional Formatting > New Rule > Use a Formula to determine which cells to format
3. In the formula bar, type in =ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0)) and select how you want those rows formatted

And that should do the trick.

The selected answer would work for as long as you know the key itself that you want to delete but if it should be truly dynamic you would need to use the [] notation instead of the dot notation.

For example:

var keyToDelete = "key1";
var myObj = {"test": {"key1": "value", "key2": "value"}}

//that will not work.
delete myObj.test.keyToDelete 

instead you would need to use:

delete myObj.test[keyToDelete];

Substitute the dot notation with [] notation for those values that you want evaluated before being deleted.

I think this will help : In Controller get the list items and selected value

public ActionResult Edit(int id)
{
    ItemsStore item = itemStoreRepository.FindById(id);
    ViewBag.CategoryId = new SelectList(categoryRepository.Query().Get(), 
                                        "Id", "Name",item.CategoryId);

    // ViewBag to pass values to View and SelectList
    //(get list of items,valuefield,textfield,selectedValue)

    return View(item);
}

and in View

@Html.DropDownList("CategoryId",String.Empty)

You may have more than one org.springframework.beans.factory.config.PropertyPlaceholderConfigurer in your application. Try setting a breakpoint on the setLocations method of the superclass and see if it's called more than once at application startup. If there is more than one org.springframework.beans.factory.config.PropertyPlaceholderConfigurer, you might need to look at configuring the ignoreUnresolvablePlaceholders property so that your application will start up cleanly.

Best way to compare undefined or null or 0 with ES5 and ES6 standards

 if ((Boolean(some_variable_1) && Boolean(some_variable_2)) === false) {
    // do something
    }

you can use WMI in .net too but you're then dependent on the wmi service running etc. Sometimes it works locally, but then fail when the same code is run on servers. I believe that's a namespace issue, related to the "names" whose values you're reading.

This will test if strings are made up of some combination or digits, the dollar sign, and a commas. Is that what you're looking for?

import re

s1 = 'Testing string'
s2 = '1234,12345$'

regex = re.compile('[0-9,$]+$')

if ( regex.match(s1) ):
   print "s1 matched"
else:
   print "s1 didn't match"

if ( regex.match(s2) ):
   print "s2 matched"
else:
   print "s2 didn't match"

--- Shameless plug ---
I have added this function to a library I created vanillajs-browser-helpers: https://github.com/Tokimon/vanillajs-browser-helpers/blob/master/inView.js
-------------------------------

Well BenM stated, you need to detect the height of the viewport + the scroll position to match up with your top position. The function you are using is ok and does the job, though its a bit more complex than it needs to be.

If you don't use jQuery then the script would be something like this:

function posY(elm) {
    var test = elm, top = 0;

    while(!!test && test.tagName.toLowerCase() !== "body") {
        top += test.offsetTop;
        test = test.offsetParent;
    }

    return top;
}

function viewPortHeight() {
    var de = document.documentElement;

    if(!!window.innerWidth)
    { return window.innerHeight; }
    else if( de && !isNaN(de.clientHeight) )
    { return de.clientHeight; }
    
    return 0;
}

function scrollY() {
    if( window.pageYOffset ) { return window.pageYOffset; }
    return Math.max(document.documentElement.scrollTop, document.body.scrollTop);
}

function checkvisible( elm ) {
    var vpH = viewPortHeight(), // Viewport Height
        st = scrollY(), // Scroll Top
        y = posY(elm);
    
    return (y > (vpH + st));
}

Using jQuery is a lot easier:

function checkVisible( elm, evalType ) {
    evalType = evalType || "visible";

    var vpH = $(window).height(), // Viewport Height
        st = $(window).scrollTop(), // Scroll Top
        y = $(elm).offset().top,
        elementHeight = $(elm).height();

    if (evalType === "visible") return ((y < (vpH + st)) && (y > (st - elementHeight)));
    if (evalType === "above") return ((y < (vpH + st)));
}

This even offers a second parameter. With "visible" (or no second parameter) it strictly checks whether an element is on screen. If it is set to "above" it will return true when the element in question is on or above the screen.

See in action: http://jsfiddle.net/RJX5N/2/

I hope this answers your question.

-- IMPROVED VERSION--

This is a lot shorter and should do it as well:

function checkVisible(elm) {
  var rect = elm.getBoundingClientRect();
  var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
  return !(rect.bottom < 0 || rect.top - viewHeight >= 0);
}

with a fiddle to prove it: http://jsfiddle.net/t2L274ty/1/

And a version with threshold and mode included:

function checkVisible(elm, threshold, mode) {
  threshold = threshold || 0;
  mode = mode || 'visible';

  var rect = elm.getBoundingClientRect();
  var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
  var above = rect.bottom - threshold < 0;
  var below = rect.top - viewHeight + threshold >= 0;

  return mode === 'above' ? above : (mode === 'below' ? below : !above && !below);
}

and with a fiddle to prove it: http://jsfiddle.net/t2L274ty/2/

Every Set has an iterator(). A normal HashSet's iterator is quite random, a TreeSet does it by sort order, a LinkedHashSet iterator iterates by insert order.

You can't replace an element in a LinkedHashSet, however. You can remove one and add another, but the new element will not be in the place of the original. In a LinkedHashMap, you can replace a value for an existing key, and then the values will still be in the original order.

Also, you can't insert at a certain position.

Maybe you'd better use an ArrayList with an explicit check to avoid inserting duplicates.

You can solve your issue by using the 'contains' function within your Xpath query, as below:

var allElementsWithClassFloat = 
   _doc.DocumentNode.SelectNodes("//*[contains(@class,'float')]")

To reuse this in a function do something similar to the following:

string classToFind = "float";    
var allElementsWithClassFloat = 
   _doc.DocumentNode.SelectNodes(string.Format("//*[contains(@class,'{0}')]", classToFind));

Another way to write text to file using cat would be something like this

cat >file.txt <<< Write something here

Here what i did and it worked for me i use firebase and when user is logIn i wanted to refresh current Fragment first you will need to requer context from activity because fragment dont have a way to get context unless you set it from Activity or context here is the code i used and worked in kotlin language i think you could use the same in java class

   override fun setUserVisibleHint(isVisibleToUser: Boolean) {
    super.setUserVisibleHint(isVisibleToUser)
    val context = requireActivity()
    if (auth.currentUser != null) {
        if (isVisibleToUser){
            context.supportFragmentManager.beginTransaction().detach(this).attach(this).commit()
        }
    }

}

The other answers are not wrong, but I found this to be the fastest way.

1. Download the zip file from Google fonts and unzip it.
2. Upload the font files 3 at a time to http://www.fontsquirrel.com/tools/webfont-generator
3. Download the results.

Results contain all font formats: woff, svg, ttf, eot.

AND as an added bonus they generate the css file for you too!

A string is a collection of char's (16bit unsigned). So if you are going to convert negative numbers into a string, they'll be lost in translation.

The Sortable JS library is compatible with touch screens and does not require jQuery.

The way it handles touch screens it that you need to touch the screen for about 1 second to start dragging an item.

Also, they present a video test showing that this library is running faster than JQuery UI Sortable.

I just want to build upon Serpens answer and add the line:

logger.setLevel('DEBUG')

This will allow you to chose what level of message gets logged.

For example in Serpens example,

logger.info('Info message')

Will not get recorded as it defaults to only recording Warnings and above.

More about levels used can be read about here

Use int(your non integer number) will nail it.

print int(2.3) # "2"
print int(math.sqrt(5)) # "2"

After digging into hibernate source code and Below configuration goes to Oracle db for the next value after 50 inserts. So make your INST_PK_SEQ increment 50 each time it is called.

Hibernate 5 is used for below strategy

Check also below http://docs.jboss.org/hibernate/orm/5.1/userguide/html_single/Hibernate_User_Guide.html#identifiers-generators-sequence

@Id
@Column(name = "ID")
@GenericGenerator(name = "INST_PK_SEQ", 
strategy = "org.hibernate.id.enhanced.SequenceStyleGenerator",
parameters = {
        @org.hibernate.annotations.Parameter(
                name = "optimizer", value = "pooled-lo"),
        @org.hibernate.annotations.Parameter(
                name = "initial_value", value = "1"),
        @org.hibernate.annotations.Parameter(
                name = "increment_size", value = "50"),
        @org.hibernate.annotations.Parameter(
                name = SequenceStyleGenerator.SEQUENCE_PARAM, value = "INST_PK_SEQ"),
    }
)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "INST_PK_SEQ")
private Long id;

You can use Message box to show success message. This works great for me.

MessageBox.Show("Data inserted successfully");

On Windows 10 - this is a workaround and does not fix the root issue however, if you just need to install something and move on; Execute the following at the command prompt, powershell or dockerfile:

pip config set global.trusted_host "pypi.org files.pythonhosted.org"

You could create a List<Object>, but you really don't want to do this. Mixed lists that abstract to Object are not very useful and are a potential source of bugs. In fact the fact that your code requires such a construct gives your code a bad code smell and suggests that its design may be off. Consider redesigning your program so you aren't forced to collect oranges with orangutans.

Instead -- do what G V recommends and I was about to recommend, create a custom class that holds both int and String and create an ArrayList of it. 1+ to his answer!

h() is also useful for escaping quotes.

For example, I have a view that generates a link using a text field result[r].thtitle. The text could include single quotes. If I didn't escape result[r].thtitle in the confirm method, the Javascript would break:

<%= link_to_remote "#{result[r].thtitle}", :url=>{ :controller=>:resource,
:action         =>:delete_resourced,
:id     => result[r].id,
:th     => thread,                                                                                                      
:html       =>{:title=> "<= Remove"},

If you don't want to stretch the image, fit it into div container without overflow and center it by adjusting it's margin if needed.

1. The image will not get cropped
   
2. The aspect ratio will also remain the same.

HTML:

<div id="app">
    <div id="container">
      <img src="#" alt="something">
    </div>
    <div id="container">
      <img src="#" alt="something">
    </div>
    <div id="container">
      <img src="#" alt="something">
    </div>
</div>

CSS:

div#container {
    height: 200px;
    width: 200px;
    border: 1px solid black;
    margin: 4px;
}
img {
    max-width: 100%;
    max-height: 100%;
    display: block;
    margin: 0 auto;
}

FOR XLSX USE

SET IN $xlsName name from XLSX with extension. Example: $xlsName = 'teste.xlsx';

$objPHPExcel = new PHPExcel();

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$xlsName.'"');
header('Cache-Control: max-age=0');
$objWriter->save('php://output');

FOR XLS USE

SET IN $xlsName name from XLS with extension. Example: $xlsName = 'teste.xls';

$objPHPExcel = new PHPExcel();

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$xlsName.'"');
header('Cache-Control: max-age=0');
$objWriter->save('php://output');

There are a few possible ways to do this:

• Set the environment variable PYTHONPATH to a colon-separated list of directories to search for imported modules.
• In your program, use sys.path.append('/path/to/search') to add the names of directories you want Python to search for imported modules. sys.path is just the list of directories Python searches every time it gets asked to import a module, and you can alter it as needed (although I wouldn't recommend removing any of the standard directories!). Any directories you put in the environment variable PYTHONPATH will be inserted into sys.path when Python starts up.
• Use site.addsitedir to add a directory to sys.path. The difference between this and just plain appending is that when you use addsitedir, it also looks for .pth files within that directory and uses them to possibly add additional directories to sys.path based on the contents of the files. See the documentation for more detail.

Which one of these you want to use depends on your situation. Remember that when you distribute your project to other users, they typically install it in such a manner that the Python code files will be automatically detected by Python's importer (i.e. packages are usually installed in the site-packages directory), so if you mess with sys.path in your code, that may be unnecessary and might even have adverse effects when that code runs on another computer. For development, I would venture a guess that setting PYTHONPATH is usually the best way to go.

However, when you're using something that just runs on your own computer (or when you have nonstandard setups, e.g. sometimes in web app frameworks), it's not entirely uncommon to do something like

import sys
from os.path import dirname
sys.path.append(dirname(__file__))

I suggest to use jQuery:

$('#mydiv')
  .css('cursor', 'pointer')
  .click(
    function(){
     alert('Click event is fired');
    }
  )
  .hover(
    function(){
      $(this).css('background', '#ff00ff');
    },
    function(){
      $(this).css('background', '');
    }
  );

As said in previous answers the 'normal' way is to add it to a JScrollPane, but sometimes you don't want it to scroll (don't ask me when:)). Then you can add the TableHeader yourself. Like this:

JPanel tablePanel = new JPanel(new BorderLayout());
JTable table = new JTable();
tablePanel.add(table, BorderLayout.CENTER);
tablePanel.add(table.getTableHeader(), BorderLayout.NORTH);

I agree with all other posters that say "don't do that" or "SQL isn't good at that". If you want to sort by some facet of comments then add another integer column to one of your tables to hold your sort criteria and sort by that value. eg "ORDER BY comments.sort DESC " If you want to sort these in a different order every time then... SQL won't be for you in this case.

ORA-12560: TNS:erro de adaptador de protocolo

1. set Environment Variables: ORACLE_BASE, ORACLE_HOME, ORACLE_SID
2. make sure your user is part of ORACLE_GROUP_NAME (Windows)
3. make sure the file ORACLE_HOME/network/admin/sqlnet.ora is: SQLNET.AUTHENTICATION_SERVICES = (NTS)
4. (Windows) Be carefull when you add a new Oracle client: adding a new path to the PATH env. variable can mess things up. The first entry in this variable makes a difference: certify that the sqlplus executable in the ORACLE_HOME (ORACLE_HOME/bin) comes first in the PATH env. variable.

From my experience the only (very) slight advantage of the first form is code readability, the second form adds "noise".

But with modern IDEs and code autogeneration (or autocompletion) I strongly recommend using the second form, you won't spend extra time typing curly braces and you'll avoid some of the most frequent bugs.

There are enough energy consuming bugs, people just shoudn't open doors for big wastes of time.

One of the most important rule to remember when writing code is consistency. Every line of code should be written the same way, no matter who wrote it. Being rigorous prevents bugs from "happening" ;)

This is the same with naming clearly & explicitly your variables, methods, files or with correctly indenting them...

When my students accept this fact, they stop fighting against their own sourcecode and they start to see coding as a really interesting, stimulating and creative activity. They challenge their minds, not their nerves !

I found this worked for me.

$username = 'user'
$password = 'password'

$securePassword = ConvertTo-SecureString $password -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential $username, $securePassword
Start-Process Notepad.exe -Credential $credential

Updated: changed to using single quotes to avoid special character issues noted by Paddy.

I've a way and work like this:

<'a href="FOLDER_PATH" target="_explorer.exe">Link Text<'/a>

Something like this:

$.getJSON("http://mywebsite.com/json/get.php?cid=15",
        function(data){
          $.each(data.products, function(i,product){
            content = '<p>' + product.product_title + '</p>';
            content += '<p>' + product.product_short_description + '</p>';
            content += '<img src="' + product.product_thumbnail_src + '"/>';
            content += '<br/>';
            $(content).appendTo("#product_list");
          });
        });

Would take a json object made from a PHP array returned with the key of products. e.g:

Array('products' => Array(0 => Array('product_title' => 'Product 1',
                                     'product_short_description' => 'Product 1 is a useful product',
                                     'product_thumbnail_src' => '/images/15/1.jpg'
                                    )
                          1 => Array('product_title' => 'Product 2',
                                     'product_short_description' => 'Product 2 is a not so useful product',
                                     'product_thumbnail_src' => '/images/15/2.jpg'
                                    )
                         )
     )

To reload the list you would simply do:

$("#product_list").empty();

And then call getJSON again with new parameters.

Since I don't see it mentioned here I thought I'd also point out that the jQuery when statement can be very useful for this purpose.

Their example looks like this:

$.when( $.ajax( "test.aspx" ) ).then(function( data, textStatus, jqXHR ) {
  alert( jqXHR.status ); // Alerts 200
});

The "then" part won't execute until the "when" part finishes.

I have used $env:username in the past, but a colleague pointed out it's an environment variable and can be changed by the user and therefore, if you really want to get the current user's username, you shouldn't trust it.

I'd upvote Mark Seemann's answer: [System.Security.Principal.WindowsIdentity]::GetCurrent().Name

But I'm not allowed to. With Mark's answer, if you need just the username, you may have to parse it out since on my system, it returns hostname\username and on domain joined machines with domain accounts it will return domain\username.

I would not use whoami.exe since it's not present on all versions of Windows, and it's a call out to another binary and may give some security teams fits.

Basically, it's a shortcut of:

class Genre{
    private string genre;
    public string getGenre() {
        return this.genre;
    }
    public void setGenre(string theGenre) {
        this.genre = theGenre;
    }
}
//In Main method
genre g1 = new Genre();
g1.setGenre("Female");
g1.getGenre(); //Female

After speaking with an LDAP expert, it's not possible this way. One query can't search more than one DC or OU.

Your options are:

1. Run more then 1 query and parse the result.
2. Use a filter to find the desired users/objects based off a different attribute like an AD group or by name.

You can use the builtin sorted function to sort the strings however you want. Based on what you describe,

sorted(os.listdir(whatever_directory))

Alternatively, you can use the .sort method of a list:

lst = os.listdir(whatever_directory)
lst.sort()

I think should do the trick.

Note that the order that os.listdir gets the filenames is probably completely dependent on your filesystem.

The first thing that we need to do is install NVM.

1. Uninstall existing version of node since we won’t be using it anymore
2. Delete any existing nodejs installation directories. e.g. “C:\Program Files\nodejs”) that might remain. NVM’s generated symlink will not overwrite an existing (even empty) installation directory.
3. Delete the npm install directory at C:\Users[Your User]\AppData\Roaming\npm We are now ready to install nvm. Download the installer from https://github.com/coreybutler/nvm/releases

To upgrade, run the new installer. It will safely overwrite the files it needs to update without touching your node.js installations. Make sure you use the same installation and symlink folder. If you originally installed to the default locations, you just need to click “next” on each window until it finishes.

From API level 17 and above, you can call: View.generateViewId()

Then use View.setId(int).

If your app is targeted lower than API level 17, use ViewCompat.generateViewId()

Simple example that you probably have seen many times before

int main(int argc, char **argv)

In the second parameter you have it: pointer to pointer to char.

Note that the pointer notation (char* c) and the array notation (char c[]) are interchangeable in function arguments. So you could also write char *argv[]. In other words char *argv[] and char **argv are interchangeable.

What the above represents is in fact an array of character sequences (the command line arguments that are given to a program at startup).

See also this answer for more details about the above function signature.

My problem was that I needed to have the "" outside the expression since I have a dynamic variable inside the sed expression itself. So than the actual solution is that one from lenn jackman that you replace the " inside the sed regex with [\"].

So my complete bash is:

RELEASE_VERSION="0.6.6"

sed -i -e "s#value=[\"]trunk[\"]#value=\"tags/$RELEASE_VERSION\"#g" myfile.xml

Here is:

# is the sed separator

[\"] = " in regex

value = \"tags/$RELEASE_VERSION\" = my replacement string, important it has just the \" for the quotes

Try this:

$("button").click(function () {
    $(this).parents("div:first").html(...);
});

Yes. But place your "test" after the comma if you want the column...

> A <- matrix(sample(1:12,12,T),ncol=4)

> rownames(A) <- letters[1:3]

> colnames(A) <- letters[11:14]
> A[,"l"]
 a  b  c

Great advice on which to use for the makefile and other tools, considering non-compiler tools while deciding on which extension to use is a great approach to help find an answer that works for you.

I just wanted to add the following to help with some .cc vs .cpp info that I found. The following are extensions broken down by different environments (from the "C++ Primer Plus" book):

Unix uses: .C, .cc, .cxx, .c

GNU C++ uses: .C, .cc, .cxx, .cpp, .c++

Digital Mars uses: .cpp, .cxx

Borland C++ uses: .cpp

Watcom uses: .cpp

Microsoft Visual C++ uses: .cpp, .cxx, .cc

Metrowerks CodeWarrior uses: .cpp, .cp, .cc, .cxx, .c++

The different environments support different extensions. I too was looking to answer this question and found this post. Based on this post I think I might go with .hpp and .cpp for ease of cross-platform/cross-tool recognition.

(WHEN .wsdl is referring to .xsd/schemas using import) If you're using the WMB Tooklit (v8.0.0.4 WMB) then you can find .xsd using following steps :

Create library (optional) > Right Click , New Message Model File > Select SOAP XML > Choose Option 'I already have WSDL for my data' > 'Select file outside workspace' > 'Select the WSDL bindings to Import' (if there are multiple) > Finish.

This will give you the .xsd and .wsdl files in your Workspace (Application Perspective).

Personally, I've set up a "rule" attached to the insert statement. Say you had a "dns" table that recorded dns hits per customer on a per-time basis:

CREATE TABLE dns (
    "time" timestamp without time zone NOT NULL,
    customer_id integer NOT NULL,
    hits integer
);

You wanted to be able to re-insert rows with updated values, or create them if they didn't exist already. Keyed on the customer_id and the time. Something like this:

CREATE RULE replace_dns AS 
    ON INSERT TO dns 
    WHERE (EXISTS (SELECT 1 FROM dns WHERE ((dns."time" = new."time") 
            AND (dns.customer_id = new.customer_id)))) 
    DO INSTEAD UPDATE dns 
        SET hits = new.hits 
        WHERE ((dns."time" = new."time") AND (dns.customer_id = new.customer_id));

Update: This has the potential to fail if simultaneous inserts are happening, as it will generate unique_violation exceptions. However, the non-terminated transaction will continue and succeed, and you just need to repeat the terminated transaction.

However, if there are tons of inserts happening all the time, you will want to put a table lock around the insert statements: SHARE ROW EXCLUSIVE locking will prevent any operations that could insert, delete or update rows in your target table. However, updates that do not update the unique key are safe, so if you no operation will do this, use advisory locks instead.

Also, the COPY command does not use RULES, so if you're inserting with COPY, you'll need to use triggers instead.

    <select name="select_box"  multiple>
        <option>123</option>
        <option>456</option>
        <option>789</option>
     </select>

this worked for me.

Here's a simple small function that can be applied anywhere as long as you're using jQuery.

var redirect = 'http://www.website.com/page?id=23231';
$.redirectPost(redirect, {x: 'example', y: 'abc'});

// jquery extend function
$.extend(

        });
        $('<form action="' + location + '" method="POST">' + form + '</form>').appendTo($(document.body)).submit();
    }
});

For implementing the timeout on the function, this stackoverflow thread has answers on that.

Anytime you have a question about a particular function in PHP, the easiest way to get quick answers is by visiting php.net, which has great documentation on all of the language's capabilities.

Looking up a function is easy, just visit http://php.net/<function name> and it will forward you to the appropriate place. For the date function, we'll visit http://php.net/date.

We immediately learn a couple things about this function by examining its signature:

string date ( string $format [, int $timestamp = time() ] )

First, it returns a string. That's what the first string in the above code means. Secondly, the first parameter is expected to be a string containing the format. There is an optional second parameter for passing in your own timestamp (to construct strings from some time other than now).

date("d-m-Y") // produces something like 03-12-2012

In this code, d represents the day of the month (with a leading 0 is necessary). m represents the month, again with a leading zero if necessary. And Y represents the full 4-digit year. All of these are documented in the aforementioned link.

To satisfy your request of getting the hours, minutes, and seconds, we need to give a quick look at the documentation to see which characters represents those particular units of time. When we do that, we find the following:

h   12-hour format of an hour with leading zeros    01 through 12
i   Minutes with leading zeros                      00 to 59
s   Seconds, with leading zeros                     00 through 59

With this in mind, we can no create a new format string:

date("d-m-Y h:i:s"); // produces something like 03-12-2012 03:29:13

Hope this is helpful, and I hope you find the documentation has benefiting to your development as I have to mine.

I believe it's most commonly called the "splat operator." Unpacking arguments is what it does.

Flushing the output buffers:

printf("Buffered, will be flushed");
fflush(stdout); // Prints to screen or whatever your standard out is

or

fprintf(fd, "Buffered, will be flushed");
fflush(fd);  //Prints to a file

Can be a very helpful technique. Why would you want to flush an output buffer? Usually when I do it, it's because the code is crashing and I'm trying to debug something. The standard buffer will not print everytime you call printf() it waits until it's full then dumps a bunch at once. So if you're trying to check if you're making it to a function call before a crash, it's helpful to printf something like "got here!", and sometimes the buffer hasn't been flushed before the crash happens and you can't tell how far you've really gotten.

Another time that it's helpful, is in multi-process or multi-thread code. Again, the buffer doesn't always flush on a call to a printf(), so if you want to know the true order of execution of multiple processes you should fflush the buffer after every print.

I make a habit to do it, it saves me a lot of headache in debugging. The only downside I can think of to doing so is that printf() is an expensive operation (which is why it doesn't by default flush the buffer).

As far as flushing the input buffer (stdin), you should not do that. Flushing stdin is undefined behavior according to the C11 standard §7.21.5.2 part 2:

If stream points to an output stream ... the fflush function causes any unwritten data for that stream ... to be written to the file; otherwise, the behavior is undefined.

On some systems, Linux being one as you can see in the man page for fflush(), there's a defined behavior but it's system dependent so your code will not be portable.

Now if you're worried about garbage "stuck" in the input buffer you can use fpurge() on that. See here for more on fflush() and fpurge()

You can do this with a single grep instruction, using Perl mode and \K to reset the match buffer, so you get only the branch name.

$ git branch | grep -oP "^\*\s+\K\S+$"
master

I doubt that Subclipse and then SVN can use your Eclipse proxy settings. You'll probably need to set the proxy for your SVN program itself. Trying to check out the files using SVN from the command line should tell you if that works.

If SVN can't connect either then put the proxy settings in your servers file in your Subversion settings folder (in your home folder).

If it can't do it even with the proxy settings set, then your firewall is probably blocking the methods and protocols that Subversion needs to use to download the files.

I know it's a bit late and maybe you already, indirectly, said it, but again, Kafka is not a queue at all, it's a log (as someone said above, poll based).

To make it simple, the most obvious use case when you should prefer RabbitMQ (or any queue techno) over Kafka is the following one :

You have multiple consumers consuming from a queue and whenever there is a new message in the queue and an available consumer, you want this message to be processed. If you look closely at how Kafka works, you'll notice it does not know how to do that, because of partition scaling, you'll have a consumer dedicated to a partition and you'll get into starvation issue. Issue that is easily avoided by using simple queue techno. You can think of using a thread that will dispatch the different messages from same partition, but again, Kafka does not have any selective acknowledgment mechanisms.

The most you could do is doing as those guys and try to transform Kafka as a queue : https://github.com/softwaremill/kmq

For a production system, you can use this configuration :

--ACCESS DB
REVOKE CONNECT ON DATABASE nova FROM PUBLIC;
GRANT  CONNECT ON DATABASE nova  TO user;

--ACCESS SCHEMA
REVOKE ALL     ON SCHEMA public FROM PUBLIC;
GRANT  USAGE   ON SCHEMA public  TO user;

--ACCESS TABLES
REVOKE ALL ON ALL TABLES IN SCHEMA public FROM PUBLIC ;
GRANT SELECT                         ON ALL TABLES IN SCHEMA public TO read_only ;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO read_write ;
GRANT ALL                            ON ALL TABLES IN SCHEMA public TO admin ;

var pattern = /[0-9!"£$%^&*()_+-=]/;

This tries to avoid some scenarios, just in case:

Overflowing any buffers the original string might get passed to. Slowness or oddities caused by denormal numbers like 1E-323. Passing Infinity when a finite number is expected (try 1E309 or -1E309).

This is a bug in pycharm. PyCharm seems to be expecting the referenced module to be included in an __all__ = [] statement.

For proper coding etiquette, should you include the __all__ statement from your modules? ..this is actually the question we hear young Spock answering while he was being tested, to which he responded: "It is morally praiseworthy but not morally obligatory."

To get around it, you can simply disable that (extremely non-critical) (highly useful) inspection globally, or suppress it for the specific function or statement.

To do so:

• put the caret over the erroring text ('choice', from your example above)
• Bring up the intention menu (alt-enter by default, mine is set to alt-backspace)
• hit the right arrow to open the submenu, and select the relevant action

PyCharm has its share of small bugs like this, but in my opinion its benefits far outweigh its drawbacks. If you'd like to try another good IDE, there's also Spyder/Spyderlib.

I know this is quite a bit after you asked your question, but I hope this helps (you, or someone else).

Edited: Originally, I thought that this was specific to checking __all__, but it looks like it's the more general 'Unresolved References' check, which can be very useful. It's probably best to use statement-level disabling of the feature, either by using the menu as mentioned above, or by specifying # noinspection PyUnresolvedReferences on the line preceding the statement.

Use setDate

.datepicker( "setDate" , date )

Sets the current date for the datepicker. The new date may be a Date object or a string in the current date format (e.g. '01/26/2009'), a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null to clear the selected date.

I successfully used

diff "${file1}" "${file2}" | grep "<" | sed 's/^<//g' > "${diff_file}"

Outputting the difference to a file.

As the original question does not state which NuGet frontend should be used, I would like to mention that NuGet 3.5 adds support for updating to a specific version via the command line client (which works for downgrades, too):

NuGet.exe update Common.Logging -Version 1.2.0

Parse the string into date, then compare using compareTo, before or after

Date d = new Date();
d.compareTo(anotherDate)

i.e

Date date1 = new SimpleDateFormat("MM/dd/yyyy").parse(date1string)
Date date2 = new SimpleDateFormat("MM/dd/yyyy").parse(date2string)

date1.compareTo(date2);

Copying the comment provided below by @MuhammadSaqib to complete this answer.

Returns the value 0 if the argument Date is equal to this Date; a value less than 0 if this Date is before the Date argument, and a value greater than 0 if this Date is after the Date argument. and NullPointerException - if anotherDate is null.

javadoc for compareTo http://docs.oracle.com/javase/6/docs/api/java/util/Date.html#compareTo(java.util.Date)

A simple solution to the problem is nano index.html and git or any other terminal will open the file right on the terminal, then you edit from there.

My tests with git-2.0.0 today indicate that the --mirror option does not copy hooks, the config file, the description file, the info/exclude file, and at least in my test case a few refs (which I don't understand.)

Spring cleverly treats http error codes as exceptions, and assumes that your exception handling code has the context to handle the error. To get exchange to function as you would expect it, do this:

    try {
        return restTemplate.exchange(url, httpMethod, httpEntity, String.class);
    } catch(HttpStatusCodeException e) {
        return ResponseEntity.status(e.getRawStatusCode()).headers(e.getResponseHeaders())
                .body(e.getResponseBodyAsString());
    }

This will return all the expected results from the response.

Here is the code and demo for how to check multiple check boxes...

http://jsfiddle.net/tamilmani/z8TTt/

$("#check").on("click", function () {

    var chk = document.getElementById('check').checked;
    var arr = document.getElementsByTagName("input");

    if (chk) {
        for (var i in arr) {
            if (arr[i].name == 'check') arr[i].checked = true;
        }
    } else {
        for (var i in arr) {
            if (arr[i].name == 'check') arr[i].checked = false;
        }
    }
});

I had same problem in eclipse windows that I couldn't added dependant .class files from the JNI. In order resolve the same, I ported all the code to NetBeans IDE.

Can not add all the classes files from the JNI/JNA folder in Eclipse (JAVA, Windows 7)

1. Generate a random number using your favourite random-number generator
2. Multiply and divide it to get a number matching the number of characters in your code alphabet
3. Get the item at that index in your code alphabet.
4. Repeat from 1) until you have the length you want

e.g (in pseudo code)

int myInt = random(0, numcharacters)
char[] codealphabet = 'ABCDEF12345'
char random = codealphabet[i]
repeat until long enough

If you are running Windows Server 2012 R2 then make sure to get rid of Work Folders: http://blogs.technet.com/b/filecab/archive/2013/10/15/windows-server-2012-r2-resolving-port-conflict-with-iis-websites-and-work-folders.aspx Removing Work Folders feature under File Server worked for me.

The properties that can be set for a figure is referenced here.

You could then use:

figure_number = 1;
x      = 0;   % Screen position
y      = 0;   % Screen position
width  = 600; % Width of figure
height = 400; % Height of figure (by default in pixels)

figure(figure_number, 'Position', [x y width height]);

I have a case scenario and I tried all the answers from above, but always new image was created on top of the old one. The solution that worked for me is:

imageView.setImageResource(R.drawable.image);

in my exchange the cmd-let you presented did not work, the answer was null, so I had to make a little correction and worked fine for me:

@(get-transportservice | get-messagetrackinglog -Resultsize unlimited -Start "MM/DD/AAAA HH:MM" -End "MM/DD/AAAA HH:MM" -recipients "[email protected]" | where {$_.Event
ID -eq "DELIVER"}).count

In MySQL, this works if there are multiple '=' characters in the string

SUBSTRING(supplier_reference FROM (LOCATE('=',supplier_reference)+1))

It returns the substring after(+1) having found the the first =

To put it a different way "id()" is not what you care about. You want to know if the variable name can be modified without harming the source variable name.

If you're used to C, then these are like pointer variables except you can't de-reference them to modify what they point at, but id() will tell you where they currently point.

The problem for python programmers comes when you consider deeper structures like lists or dicts:

>>> o={'a': 10}

Here o and x refer to the same dict o['a'] and x['a'], and that dict is "mutable" in the sense that you can change the value for key 'a'. That's why "y" needs to be a copy and y['a'] can refer to something else.

It the element has two xpath. Then you can write two xpaths like below:

xpath1 | xpath2

Eg:

//input[@name="username"] | //input[@id="wm_login-username"]

package main

type    Proxy struct {
        Address string
        Port    string
    }

type Configuration struct {
    Proxy
    Val   string

}

func main() {

    c := &Configuration{
        Val: "test",
        Proxy: Proxy {
            Address: "addr",
            Port:    "80",
        },
    }

}

maybe not as stylish, but easier:

#!/bin/bash
log="/var/log/yourlog"
/path/to/your/script.py 2>&1 | (while read; do echo "$REPLY" >> $log; done)

use SimpleDateFormat to first parse() String to Date and then format() Date to String

You can use the for..in TypeScript operator to access the index when dealing with collections.

var test = [7,8,9];
for (var i in test) {
   console.log(i + ': ' + test[i]);
} 

Output:

 0: 7
 1: 8
 2: 9

For i = 1 To X
    Controls("Label" & i).Caption =  MySheet.Cells(i + 1, i).Value
Next

You don't have to do anything, alias does this automatically.

For example, if i want to make git pull origin master parameterized, i can simply create an alias as follows:

alias gpull = 'git pull origin '

and when actually calling it, you can pass 'master' (the branch name) as a parameter, like this:

gpull master
//or any other branch
gpull mybranch

For anyone looking for a Xamarin implementation (since events are done differently in C#), I simply created this NavClickHandler class as follows:

public class NavClickHandler : Java.Lang.Object, View.IOnClickListener
{
    private Activity mActivity;
    public NavClickHandler(Activity activity)
    {
        this.mActivity = activity;
    }
    public void OnClick(View v)
    {
        DrawerLayout drawer = (DrawerLayout)mActivity.FindViewById(Resource.Id.drawer_layout);
        if (drawer.IsDrawerOpen(GravityCompat.Start))
        {
            drawer.CloseDrawer(GravityCompat.Start);
        }
        else
        {
            drawer.OpenDrawer(GravityCompat.Start);
        }
    }
}

Then, assigned a custom hamburger menu button like this:

        SupportActionBar.SetDisplayHomeAsUpEnabled(true);
        SupportActionBar.SetDefaultDisplayHomeAsUpEnabled(false);
        this.drawerToggle.DrawerIndicatorEnabled = false;
        this.drawerToggle.SetHomeAsUpIndicator(Resource.Drawable.MenuButton);

And finally, assigned the drawer menu toggler a ToolbarNavigationClickListener of the class type I created earlier:

        this.drawerToggle.ToolbarNavigationClickListener = new NavClickHandler(this);

And then you've got a custom menu button, with click events handled.

Process QProc = new Process();
QProc.StartInfo.FileName = "cmd";
QProc.StartInfo.Arguments ="/c InstallUtil "+ "\""+ filefullPath +"\"";
QProc.StartInfo.WorkingDirectory = Environment.GetEnvironmentVariable("windir") + @"\Microsoft.NET\Framework\v2.0.50727\";
QProc.StartInfo.UseShellExecute = false;
// QProc.StartInfo.CreateNoWindow = true;
QProc.StartInfo.RedirectStandardOutput = true;
QProc.Start();
// QProc.WaitForExit();
QProc.Close();

You can use PostBackUrl="~/Confirm.aspx"

For example:

In your .aspx file

<asp:Button ID="btnConfirm" runat="server" Text="Confirm" PostBackUrl="~/Confirm.aspx" />

or in your .cs file

btnConfirm.PostBackUrl="~/Confirm.aspx"

var inputs = events.Select(async ev => await ProcessEventAsync(ev))
                   .Select(t => t.Result)
                   .Where(i => i != null)
                   .ToList();

But this seems very weird to me, first of all the use of async and await in the select. According to this answer by Stephen Cleary I should be able to drop those.

The call to Select is valid. These two lines are essentially identical:

events.Select(async ev => await ProcessEventAsync(ev))
events.Select(ev => ProcessEventAsync(ev))

(There's a minor difference regarding how a synchronous exception would be thrown from ProcessEventAsync, but in the context of this code it doesn't matter at all.)

Then the second Select which selects the result. Doesn't this mean the task isn't async at all and is performed synchronously (so much effort for nothing), or will the task be performed asynchronously and when it's done the rest of the query is executed?

It means that the query is blocking. So it is not really asynchronous.

Breaking it down:

var inputs = events.Select(async ev => await ProcessEventAsync(ev))

will first start an asynchronous operation for each event. Then this line:

                   .Select(t => t.Result)

will wait for those operations to complete one at a time (first it waits for the first event's operation, then the next, then the next, etc).

This is the part I don't care for, because it blocks and also would wrap any exceptions in AggregateException.

and is it completely the same like this?

var tasks = await Task.WhenAll(events.Select(ev => ProcessEventAsync(ev)));
var inputs = tasks.Where(result => result != null).ToList();

var inputs = (await Task.WhenAll(events.Select(ev => ProcessEventAsync(ev))))
                                       .Where(result => result != null).ToList();

Yes, those two examples are equivalent. They both start all asynchronous operations (events.Select(...)), then asynchronously wait for all the operations to complete in any order (await Task.WhenAll(...)), then proceed with the rest of the work (Where...).

Both of these examples are different from the original code. The original code is blocking and will wrap exceptions in AggregateException.

I have written myself a function that converts most of the stuff one may want to send via AJAX to GET of POST query.
Following part of the function might be of interest:

  if(data.tagName!=null&&data.tagName.toUpperCase()=="FORM") {
    //Get all the input elements in form
    var elem = data.elements;
    //Loop through the element array
    for(var i = 0; i < elem.length; i++) {
      //Ignore elements that are not supposed to be sent
      if(elem[i].disabled!=null&&elem[i].disabled!=false||elem[i].type=="button"||elem[i].name==null||(elem[i].type=="checkbox"&&elem[i].checked==false))
        continue; 
      //Add & to any subsequent entries (that means every iteration except the first one) 
      if(data_string.length>0)
        data_string+="&";
      //Get data for selectbox
      if (elem[i].tagName.toUpperCase() == "SELECT")
      {
        data_string += elem[i].name + "=" + encodeURIComponent(elem[i].options[elem[i].selectedIndex].value) ;
      }
      //Get data from checkbox
      else if(elem[i].type=="checkbox")
      {
        data_string += elem[i].name + "="+(elem[i].value==null?"on":elem[i].value);
      }
      //Get data from textfield
      else
      {
        data_string += elem[i].name + (elem[i].value!=""?"=" + encodeURIComponent(elem[i].value):"=");
      }
    }
    return data_string; 
  }

It does not need jQuery since I don't use it. But I'm sure jquery's $.post accepts string as seconf argument.

Here is the whole function, other parts are not commented though. I can't promise there are no bugs in it:

function ajax_create_request_string(data, recursion) {
  var data_string = '';
  //Zpracovani formulare
  if(data.tagName!=null&&data.tagName.toUpperCase()=="FORM") {
    //Get all the input elements in form
    var elem = data.elements;
    //Loop through the element array
    for(var i = 0; i < elem.length; i++) {
      //Ignore elements that are not supposed to be sent
      if(elem[i].disabled!=null&&elem[i].disabled!=false||elem[i].type=="button"||elem[i].name==null||(elem[i].type=="checkbox"&&elem[i].checked==false))
        continue; 
      //Add & to any subsequent entries (that means every iteration except the first one) 
      if(data_string.length>0)
        data_string+="&";
      //Get data for selectbox
      if (elem[i].tagName.toUpperCase() == "SELECT")
      {
        data_string += elem[i].name + "=" + encodeURIComponent(elem[i].options[elem[i].selectedIndex].value) ;
      }
      //Get data from checkbox
      else if(elem[i].type=="checkbox")
      {
        data_string += elem[i].name + "="+(elem[i].value==null?"on":elem[i].value);
      }
      //Get data from textfield
      else
      {
        if(elem[i].className.indexOf("autoempty")!=-1) {
          data_string += elem[i].name+"=";
        }
        else
          data_string += elem[i].name + (elem[i].value!=""?"=" + encodeURIComponent(elem[i].value):"=");
      }
    }
    return data_string; 
  }
  //Loop through array
  if(data instanceof Array) {
    for(var i=0; i<data.length; i++) {
      if(data_string!="")
        data_string+="&";
      data_string+=recursion+"["+i+"]="+data[i];
    }
    return data_string;
  }
  //Loop through object (like foreach)
  for(var i in data) {
    if(data_string!="")
      data_string+="&";
    if(typeof data[i]=="object") {
      if(recursion==null)
        data_string+= ajax_create_request_string(data[i], i);
      else
        data_string+= ajax_create_request_string(data[i], recursion+"["+i+"]");
    }
    else if(recursion==null)
      data_string+=i+"="+data[i];
    else 
      data_string+=recursion+"["+i+"]="+data[i];
  }
  return data_string;
}

Put this bean in your configuration class.

 @Bean
  public Validator localValidatorFactoryBean() {
    return new LocalValidatorFactoryBean();
  }

and then You can use

 <T> BindingResult validate(T t) {
    DataBinder binder = new DataBinder(t);
    binder.setValidator(validator);
    binder.validate();
    return binder.getBindingResult();
}

for validating a bean manually. Then You will get all result in BindingResult and you can retrieve from there.

You are mixing a lot of things, which makes it hard to answer your question. The short answer is: As far as I know, what you want to do is just not possible in Python - for good reason!

The longer answer is that you should make yourself more comfortable with Python, if you want to develop in Python. Comprehensions are not hard to read. You might not be used to reading them, but you have to get used to it if you want to be a Python developer. If there is a language that fits your needs better, choose that one. If you choose Python, be prepared to solve problems in a pythonic way. Of course you are free to fight against Python, But it will not be fun! ;-)

And if you would tell us what your real problem is, you might even get a pythonic answer. "Getting something in one line" us usually not a programming problem.

Use this code

<?xml version="1.0" encoding="utf-8"?>

You can get some inspiration by reading an entrypoint.sh script written by the contributors from MySQL that checks whether the specified variables were set.

As the script shows, you can pipe them with -a, e.g.:

if [ -z "$MYSQL_ROOT_PASSWORD" -a -z "$MYSQL_ALLOW_EMPTY_PASSWORD" -a -z "$MYSQL_RANDOM_ROOT_PASSWORD" ]; then
    ...
fi

So, $HOME is what I need to modify.

However I have been unable to find where this mythical $HOME variable is set so I assumed it was a Linux system version of PATH or something.

Git 2.23 (Q3 2019) is quite explicit on how HOME is set.

See commit e12a955 (04 Jul 2019) by Karsten Blees (kblees).
^{(Merged by Junio C Hamano -- gitster -- in commit fc613d2, 19 Jul 2019)}

mingw: initialize HOME on startup

HOME initialization was historically duplicated in many different places, including /etc/profile, launch scripts such as git-bash.vbs and gitk.cmd, and (although slightly broken) in the git-wrapper.

Even unrelated projects such as GitExtensions and TortoiseGit need to implement the same logic to be able to call git directly.

Initialize HOME in Git's own startup code so that we can eventually retire all the duplicate initialization code.

Now, mingw.c includes the following code:

/* calculate HOME if not set */
if (!getenv("HOME")) {
    /*
     * try $HOMEDRIVE$HOMEPATH - the home share may be a network
     * location, thus also check if the path exists (i.e. is not
     * disconnected)
     */
    if ((tmp = getenv("HOMEDRIVE"))) {
        struct strbuf buf = STRBUF_INIT;
        strbuf_addstr(&buf, tmp);
        if ((tmp = getenv("HOMEPATH"))) {
            strbuf_addstr(&buf, tmp);
            if (is_directory(buf.buf))
                setenv("HOME", buf.buf, 1);
            else
                tmp = NULL; /* use $USERPROFILE */
        }
        strbuf_release(&buf);
    }
    /* use $USERPROFILE if the home share is not available */
    if (!tmp && (tmp = getenv("USERPROFILE")))
        setenv("HOME", tmp, 1);
}

There is no "quick-and-dirty" way of doing this. I usually do:

mystring= string.Concat(mystring.Take(mystring.Length-1));

Another quicker option to call things (like DialogBoxes and MessageBoxes and creating separate threads for not-thread safe methods) would be to use the Lamba Expression

  new Thread(() -> {
                      "code here"
            }).start();

this works too.

df = NULL
for (k in 1:10)
    {
       x = 1
       y = 2
       z = 3
       df = rbind(df, data.frame(x,y,z))
     }

output will look like this

df #enter

x y z #col names
1 2 3

Choosing the right file format is important to building performant data applications. The concepts outlined in this post carry over to Pandas, Dask, Spark, and Presto / AWS Athena.

Column pruning

Column pruning is a big performance improvement that's possible for column-based file formats (Parquet, ORC) and not possible for row-based file formats (CSV, Avro).

Suppose you have a dataset with 100 columns and want to read two of them into a DataFrame. Here's how you can perform this with Pandas if the data is stored in a Parquet file.

import pandas as pd

pd.read_parquet('some_file.parquet', columns = ['id', 'firstname'])

Parquet is a columnar file format, so Pandas can grab the columns relevant for the query and can skip the other columns. This is a massive performance improvement.

If the data is stored in a CSV file, you can read it like this:

import pandas as pd

pd.read_csv('some_file.csv', usecols = ['id', 'firstname'])

usecols can't skip over entire columns because of the row nature of the CSV file format.

Spark doesn't require users to explicitly list the columns that'll be used in a query. Spark builds up an execution plan and will automatically leverage column pruning whenever possible. Of course, column pruning is only possible when the underlying file format is column oriented.

Popularity

Spark and Pandas have built-in readers writers for CSV, JSON, ORC, Parquet, and text files. They don't have built-in readers for Avro.

Avro is popular within the Hadoop ecosystem. Parquet has gained significant traction outside of the Hadoop ecosystem. For example, the Delta Lake project is being built on Parquet files.

Arrow is an important project that makes it easy to work with Parquet files with a variety of different languages (C, C++, Go, Java, JavaScript, MATLAB, Python, R, Ruby, Rust), but doesn't support Avro. Parquet files are easier to work with because they are supported by so many different projects.

Schema

Parquet stores the file schema in the file metadata. CSV files don't store file metadata, so readers need to either be supplied with the schema or the schema needs to be inferred. Supplying a schema is tedious and inferring a schema is error prone / expensive.

Avro also stores the data schema in the file itself. Having schema in the files is a huge advantage and is one of the reasons why a modern data project should not rely on JSON or CSV.

Column metadata

Parquet stores metadata statistics for each column and lets users add their own column metadata as well.

The min / max column value metadata allows for Parquet predicate pushdown filtering that's supported by the Dask & Spark cluster computing frameworks.

Here's how to fetch the column statistics with PyArrow.

import pyarrow.parquet as pq

parquet_file = pq.ParquetFile('some_file.parquet')
print(parquet_file.metadata.row_group(0).column(1).statistics)

<pyarrow._parquet.Statistics object at 0x11ac17eb0>
  has_min_max: True
  min: 1
  max: 9
  null_count: 0
  distinct_count: 0
  num_values: 3
  physical_type: INT64
  logical_type: None
  converted_type (legacy): NONE

Complex column types

Parquet allows for complex column types like arrays, dictionaries, and nested schemas. There isn't a reliable method to store complex types in simple file formats like CSVs.

Compression

Columnar file formats store related types in rows, so they're easier to compress. This CSV file is relatively hard to compress.

first_name,age
ken,30
felicia,36
mia,2

This data is easier to compress when the related types are stored in the same row:

ken,felicia,mia
30,36,2

Parquet files are most commonly compressed with the Snappy compression algorithm. Snappy compressed files are splittable and quick to inflate. Big data systems want to reduce file size on disk, but also want to make it quick to inflate the flies and run analytical queries.

Mutable nature of file

Parquet files are immutable, as described here. CSV files are mutable.

Adding a row to a CSV file is easy. You can't easily add a row to a Parquet file.

Data lakes

In a big data environment, you'll be working with hundreds or thousands of Parquet files. Disk partitioning of the files, avoiding big files, and compacting small files is important. The optimal disk layout of data depends on your query patterns.

I'd like to recommend var_export($array) - it doesn't show types, but it generates syntax you can use in your code :)

At the moment this doesn't really exist (although you can of course write your own). There is an open connect bug for it: https://connect.microsoft.com/SQLServer/Feedback/Details/3130221, which as of this writing has just 1 vote.

I was facing the similar problem in OSx. My stacktrace was saying

raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: setuptools>=11.3

Then I did the following

sudo pip install --upgrade setuptools

This solved the problem for me. Hope someone will find this useful.

If you want rounded corner of UI objects like (UILabel, UIView, UIButton, UIImageView) by storyboard then set clip to bounds true and set User Defined Runtime Attributes Key path as layer.cornerRadius, type = Number and value = 9 (as your requirement)

To escape %, you will need to double it up: %%.

You can do something like:

module.exports = {
    method: function() {},
    otherMethod: function() {},
};

Or just:

exports.method = function() {};
exports.otherMethod = function() {};

Then in the calling script:

const myModule = require('./myModule.js');
const method = myModule.method;
const otherMethod = myModule.otherMethod;
// OR:
const {method, otherMethod} = require('./myModule.js');

There is only DateTime type in C# and it consist of both the date and time portion. If you don't care about the Date portion of DateTime, set it to default value like this:

DateTime myTime = default(DateTime).Add(myDateTime.TimeOfDay)

This way you can be consistent across all versions of .NET, even if Microsoft decides to change the base date to something else than 1/1/0001.

One might consider using MessagePack which is endorsed by redis.

import msgpack

data = {
    'one': 'one',
    'two': 2,
    'three': [1, 2, 3]
}

await redis.set('my-key', msgpack.packb(data))
val = await redis.get('my-key')
print(msgpack.unpackb(val))

# {'one': 'one', 'two': 2, 'three': [1, 2, 3]}

Using msgpack-python and aioredis

Gulp will do the job for watching your sass files and also adding paths of other file with includePaths. example:

gulp.task('sass', function() {
  return gulp.src('scss/app.scss')
    .pipe($.sass({
      includePaths: sassPaths
    })
    .pipe(gulp.dest('css'));
});

In your controller, you are using an http scheme, but I think you should be using a ws scheme, as you are using websockets. Try to use ws://localhost:3000 in your connect function.

For static import select the field and press Ctrl+Shift+M

Follow these steps:

1. Add path to gitignore file

2. Run this command

   git rm -r --cached foldername
   

3. commit changes as usually.

Use android:scaleType="centerCrop".

SELECT * FROM table ORDER BY id DESC,datechat desc LIMIT 50

If you have a date field that is storing the date(and time) on which the chat was sent or any field that is filled with incrementally(order by DESC) or desinscrementally( order by ASC) data per row put it as second column on which the data should be order.

That's what worked for me!!!! hope it will help!!!!

my sample code

wv = (WebView) findViewById(R.id.mywebview);
wv.getLayoutParams().height = LayoutParams.MATCH_PARENT; // LayoutParams: android.view.ViewGroup.LayoutParams
// wv.getLayoutParams().height = LayoutParams.WRAP_CONTENT;
wv.requestLayout();//It is necesary to refresh the screen

If you have ERROR 1064 (42000) or ERROR 1046 (3D000): No database selected in Mysql 5.7, you must specify the location of the user table, the location is mysql.table_name Then the code will work.

sudo mysql -u root -p

UPDATE mysql.user SET authentication_string=password('elephant7') WHERE user='root';

SERIOUS DISCLAIMER

This solution has a serious security flaw. Please use at your own risk.
Have a look at the comments on this post, and look at all the answers to this question.

OK, I had to go to the customer premises and found a solution. I:

• Exported the keystore that holds the signing keys in PKCS #12 format
• Opened control panel Java -> Security tab
• Clicked Manage certificates
• Imported this new keystore as a secure site CA

Then I opened the JAWS application without any warning. This is a little bit cumbersome, but much cheaper than buying a signed certificate!

SELECT * INTO requires that the destination table not exist.

Try this.

INSERT INTO db1.dbo.TempTable
 (List of columns here)
SELECT (Same list of columns here)
FROM db2.dbo.TempTable

I wanted a profile picture of size 96x96 with data from api. The following solution worked for me in project Angular 7.

.ts:

  @Input() profile;

.html:

 <span class="avatar" [ngStyle]="{'background-image': 'url('+ profile?.public_picture +')'}"></span>

.scss:

 .avatar {
      border-radius: 100%;
      background-size: cover;
      background-position: center center;
      background-repeat: no-repeat;
      width: 96px;
      height: 96px;
    }

Please note that if you write background instead of 'background-image' in [ngStyle], the styles you write (even in style of element) for other background properties like background-position/size, etc. won't work. Because you will already fix it's properties with background: 'url(+ property +) (no providers for size, position, etc. !)'. The [ngStyle] priority is higher than style of element. In background here, only url() property will work. Be sure to use 'background-image' instead of 'background'in case you want to write more properties to background image.

This should sort alphanumeric field like: 1/ Number only, order by 1,2,3,4,5,6,7,8,9,10,11 etc... 2/ Then field with text like: 1foo, 2bar, aaa11aa, aaa22aa, b5452 etc...

SELECT  MyField
FROM MyTable
order by 
    IF( MyField REGEXP '^-?[0-9]+$' = 0, 
    9999999999 ,  
    CAST(MyField AS DECIMAL) 
    ), MyField

The query check if the data is a number, if not put it to 9999999999 , then order first on this column, then order on data with text

Good luck!

You can try this.

func convertToJSONString(value: AnyObject) -> String? {
        if JSONSerialization.isValidJSONObject(value) {
            do{
                let data = try JSONSerialization.data(withJSONObject: value, options: [])
                if let string = NSString(data: data, encoding: String.Encoding.utf8.rawValue) {
                    return string as String
                }
            }catch{
            }
        }
        return nil
    }

If you are using Netbeans older version, you have to make changes in maven to use https over http

Open C:\Program Files\NetBeans8.0.2\java\maven\conf\settings.xml and paste below code in between mirrors tag

<mirror>
<id>maven-mirror</id>
<name>Maven Mirror</name>
<url>https://repo.maven.apache.org/maven2</url>
<mirrorOf>central</mirrorOf>
</mirror>

It will force maven to use https://repo.maven.apache.org/maven2 url.

Use underscore (or loDash :)):

var randomArray = [
   '#cc0000','#00cc00', '#0000cc'
];

// use _.sample
var randomElement = _.sample(randomArray);

// manually use _.random
var randomElement = randomArray[_.random(randomArray.length-1)];

Or to shuffle an entire array:

// use underscore's shuffle function
var firstRandomElement = _.shuffle(randomArray)[0];

Maybe this can help you also. It's from the website:

http://nathanael.hevenet.com/android-dev-changing-the-title-bar-background/

First things first you need to have a custom theme declared for your application (or activity, depending on your needs). Something like…

<!-- Somewhere in AndroidManifest.xml -->
<application ... android:theme="@style/ThemeSelector">

Then, declare your custom theme for two cases, API versions with and without the Holo Themes. For the old themes we’ll customize the windowTitleBackgroundStyle attribute, and for the newer ones the ActionBarStyle.

<!-- res/values/styles.xml -->
<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="ThemeSelector" parent="android:Theme.Light">
        <item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground</item>
    </style>

    <style name="WindowTitleBackground">     
        <item name="android:background">@color/title_background</item>
    </style>

</resources>

<!-- res/values-v11/styles.xml -->
<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="ThemeSelector" parent="android:Theme.Holo.Light">
        <item name="android:actionBarStyle">@style/ActionBar</item>
    </style>

    <style name="ActionBar" parent="android:style/Widget.Holo.ActionBar">     
        <item name="android:background">@color/title_background</item>
    </style>

</resources>

That’s it!

The selected answer doesn't have an iterator; it is more basic, but perhaps not as useful.

Here is one with an iterator/enumerator. My implementation is based on Sedgewick's bag; see http://algs4.cs.princeton.edu/13stacks/Bag.java.html

void Main()
{
    var b = new Bag<string>();
    b.Add("bike");
    b.Add("erasmus");
    b.Add("kumquat");
    b.Add("beaver");
    b.Add("racecar");
    b.Add("barnacle");

    foreach (var thing in b)
    {
        Console.WriteLine(thing);
    }
}

// Define other methods and classes here

public class Bag<T> : IEnumerable<T>
{
    public Node<T> first;// first node in list

    public class Node<T>
    {
        public T item;
        public Node<T> next;

        public Node(T item)
        {
            this.item = item;
        }
    }


    public void Add(T item)
    {
        Node<T> oldFirst = first;
        first = new Node<T>(item);
        first.next = oldFirst;
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return GetEnumerator();
    }

    public IEnumerator<T> GetEnumerator()
    {
        return new BagEnumerator<T>(this);
    }

    public class BagEnumerator<V> : IEnumerator<T>
    {
        private Node<T> _head;
        private Bag<T> _bag;
        private Node<T> _curNode;


        public BagEnumerator(Bag<T> bag)
        {

            _bag = bag;
            _head = bag.first;
            _curNode = default(Node<T>);

        }

        public T Current
        {
            get { return _curNode.item; }
        }


        object IEnumerator.Current
        {
            get { return Current; }
        }

        public bool MoveNext()
        {
            if (_curNode == null)
            {
                _curNode = _head;
                if (_curNode == null)
                return false;
                return true;
            }
            if (_curNode.next == null)
            return false;
            else
            {
                _curNode = _curNode.next;
                return true;
            }

        }

        public void Reset()
        {
            _curNode = default(Node<T>); ;
        }


        public void Dispose()
        {
        }
    }
}

Often this question is asked in the context of Ron de Bruin's RangeToHTML function, which creates an HTML PublishObject from an Excel.Range, extracts that via FSO, and inserts the resulting stream HTML in to the email's HTMLBody. In doing so, this removes the default signature (the RangeToHTML function has a helper function GetBoiler which attempts to insert the default signature).

Unfortunately, the poorly-documented Application.CommandBars method is not available via Outlook:

wdDoc.Application.CommandBars.ExecuteMso "PasteExcelTableSourceFormatting"

It will raise a runtime 6158:

But we can still leverage the Word.Document which is accessible via the MailItem.GetInspector method, we can do something like this to copy & paste the selection from Excel to the Outlook email body, preserving your default signature (if there is one).

Dim rng as Range
Set rng = Range("A1:F10") 'Modify as needed

With OutMail
    .To = "[email protected]"
    .BCC = ""
    .Subject = "Subject"
    .Display
    Dim wdDoc As Object     '## Word.Document
    Dim wdRange As Object   '## Word.Range
    Set wdDoc = OutMail.GetInspector.WordEditor
    Set wdRange = wdDoc.Range(0, 0)
    wdRange.InsertAfter vbCrLf & vbCrLf
    'Copy the range in-place
    rng.Copy
    wdRange.Paste
End With

Note that in some cases this may not perfectly preserve the column widths or in some instances the row heights, and while it will also copy shapes and other objects in the Excel range, this may also cause some funky alignment issues, but for simple tables and Excel ranges, it is very good:

You could also take a look at a past sample project of mine, written for this purpose. I saves locally a name and retrieves it either upon a user's request or when the app starts.

But, at this time, it would be better to use commit (instead of apply) for persisting the data. More info here.

I think you can use loc if you need update two columns to same value:

df1.loc[df1['stream'] == 2, ['feat','another_feat']] = 'aaaa'
print df1
   stream        feat another_feat
a       1  some_value   some_value
b       2        aaaa         aaaa
c       2        aaaa         aaaa
d       3  some_value   some_value

If you need update separate, one option is use:

df1.loc[df1['stream'] == 2, 'feat'] = 10
print df1
   stream        feat another_feat
a       1  some_value   some_value
b       2          10   some_value
c       2          10   some_value
d       3  some_value   some_value

Another common option is use numpy.where:

df1['feat'] = np.where(df1['stream'] == 2, 10,20)
print df1
   stream  feat another_feat
a       1    20   some_value
b       2    10   some_value
c       2    10   some_value
d       3    20   some_value

EDIT: If you need divide all columns without stream where condition is True, use:

print df1
   stream  feat  another_feat
a       1     4             5
b       2     4             5
c       2     2             9
d       3     1             7

#filter columns all without stream
cols = [col for col in df1.columns if col != 'stream']
print cols
['feat', 'another_feat']

df1.loc[df1['stream'] == 2, cols ] = df1 / 2
print df1
   stream  feat  another_feat
a       1   4.0           5.0
b       2   2.0           2.5
c       2   1.0           4.5
d       3   1.0           7.0

If working with multiple conditions is possible use multiple numpy.where or numpy.select:

df0 = pd.DataFrame({'Col':[5,0,-6]})

df0['New Col1'] = np.where((df0['Col'] > 0), 'Increasing', 
                          np.where((df0['Col'] < 0), 'Decreasing', 'No Change'))

df0['New Col2'] = np.select([df0['Col'] > 0, df0['Col'] < 0],
                            ['Increasing',  'Decreasing'], 
                            default='No Change')

print (df0)
   Col    New Col1    New Col2
0    5  Increasing  Increasing
1    0   No Change   No Change
2   -6  Decreasing  Decreasing

Race conditions occur in multi-threaded applications or multi-process systems. A race condition, at its most basic, is anything that makes the assumption that two things not in the same thread or process will happen in a particular order, without taking steps to ensure that they do. This happens commonly when two threads are passing messages by setting and checking member variables of a class both can access. There's almost always a race condition when one thread calls sleep to give another thread time to finish a task (unless that sleep is in a loop, with some checking mechanism).

Tools for preventing race conditions are dependent on the language and OS, but some comon ones are mutexes, critical sections, and signals. Mutexes are good when you want to make sure you're the only one doing something. Signals are good when you want to make sure someone else has finished doing something. Minimizing shared resources can also help prevent unexpected behaviors

Detecting race conditions can be difficult, but there are a couple signs. Code which relies heavily on sleeps is prone to race conditions, so first check for calls to sleep in the affected code. Adding particularly long sleeps can also be used for debugging to try and force a particular order of events. This can be useful for reproducing the behavior, seeing if you can make it disappear by changing the timing of things, and for testing solutions put in place. The sleeps should be removed after debugging.

The signature sign that one has a race condition though, is if there's an issue that only occurs intermittently on some machines. Common bugs would be crashes and deadlocks. With logging, you should be able to find the affected area and work back from there.

In the file you put in /etc/init.d/ you have to set it executable with:

chmod +x /etc/init.d/start_my_app

Thanks to @meetamit, if this does not run you have to create a symlink to /etc/rc.d/

ln -s /etc/init.d/start_my_app /etc/rc.d/

Please note that on latest Debian, this will not work as your script have to be LSB compliant (provide, at least, the following actions: start, stop, restart, force-reload, and status): https://wiki.debian.org/LSBInitScripts

As a note, you should put the absolute path of your script instead of a relative one, it may solves unexpected issues:

/var/myscripts/start_my_app

And don't forget to add on top of that file:

#!/bin/sh

Export the SELECT result

• After you run a SELECT: Query > Export Results...

  

Export table data

• In the Navigator, right click on the table > Table Data Export Wizard

  

• All columns and rows are included by default, so click on Next.

• Select File Path, type, Field Separator (by default it is ;, not ,!!!) and click on Next.

  

• Click Next > Next > Finish and the file is created in the specified location

I'm sure git subtree is all fine and wonderful, but my subdirectories of git managed code that I wanted to move was all in eclipse. So if you're using egit, it's painfully easy. Take the project you want to move and team->disconnect it, and then team->share it to the new location. It will default to trying to use the old repo location, but you can uncheck the use-existing selection and pick the new place to move it. All hail egit.

you can use skimage.img_as_ubyte(yourdata) it will make you numpy array ranges from 0->255

from skimage import img_as_ubyte

img = img_as_ubyte(data)
cv2.imshow("Window", img)

I know this is an old question, but I came across it today searching for a pre-packaged solution to this problem, and found nothing that really met my needs.

Here is a solution (English only) that correctly supports Upper Case (shifted), Lower Case, punctuation, number keypad, etc.

It also allows for simple and straight-forward identification of - and reaction to - non-printable keys, like ESC, Arrows, Function keys, etc.

keyboardCharMap and keyboardNameMap are the key to making this work

Thanks to DaveAlger for saving me some typing - and much discovery! - by providing the Named Key Array.

For Linux

Debian based distros:

sudo apt-get install python3-tk

RPM based distros:

sudo yum install python3-tkinter

For windows:

For Windows, I think the problem is you didn't install complete Python package. Since Tkinter should be shipped with Python out of box. See: http://www.tkdocs.com/tutorial/install.html . Good python distributions for Windows can be found by the companies Anaconda or ActiveState.

Test the python module

python -c "import tkinter"

p.s. I suggest installing ipython, which provides powerful shell and necessary packages as well.

The problem is that PHP mail() function has a very limited functionality. There are several ways to send mail from PHP.

1. mail() uses SMTP server on your system. There are at least two servers you can use on Windows: hMailServer and xmail. I spent several hours configuring and getting them up. First one is simpler in my opinion. Right now, hMailServer is working on Windows 7 x64.
2. mail() uses SMTP server on remote or virtual machine with Linux. Of course, real mail service like Gmail doesn't allow direct connection without any credentials or keys. You can set up virtual machine or use one located in your LAN. Most linux distros have mail server out of the box. Configure it and have fun. I use default exim4 on Debian 7 that listens its LAN interface.
3. Mailing libraries use direct connections. Libs are easier to set up. I used SwiftMailer and it perfectly sends mail from Gmail account. I think that PHPMailer is pretty good too.

No matter what choice is your, I recommend you use some abstraction layer. You can use PHP library on your development machine running Windows and simply mail() function on production machine with Linux. Abstraction layer allows you to interchange mail drivers depending on system which your application is running on. Create abstract MyMailer class or interface with abstract send() method. Inherit two classes MyPhpMailer and MySwiftMailer. Implement send() method in appropriate ways.

For the replacement portion, Python uses \1 the way sed and vi do, not $1 the way Perl, Java, and Javascript (amongst others) do. Furthermore, because \1 interpolates in regular strings as the character U+0001, you need to use a raw string or \escape it.

A fast way to convert strings to an integer is to use a bitwise or, like so:

x | 0

While it depends on how it is implemented, in theory it should be relatively fast (at least as fast as +x) since it will first cast x to a number and then perform a very efficient or.

By combining PIPESTATUS[0] and the result of executing the exit command in a subshell, you can directly access the return value of your initial command:

command | tee ; ( exit ${PIPESTATUS[0]} )

Here's an example:

# the "false" shell built-in command returns 1
false | tee ; ( exit ${PIPESTATUS[0]} )
echo "return value: $?"

will give you:

return value: 1

In case anyone needed the above in swift :

SWIFT 3.0 and above :

this will capitalize your string, make the first letter capital :

viewNoteDateMonth.text  = yourString.capitalized

this will uppercase your string, make all the string upper case :

viewNoteDateMonth.text  = yourString.uppercased()

You need to check for the parameter being blank: if "%~1"=="" goto blank

Once you've done that, then do an if/else switch on -b: if "%~1"=="-b" (goto specific) else goto unknown

Surrounding the parameters with quotes makes checking for things like blank/empty/missing parameters easier. "~" ensures double quotes are stripped if they were on the command line argument.

Extending Raufio's answer, add a __repr__ to return the value.

class const(object):
    def __init__(self, val):
        super(const, self).__setattr__("value", val)
    def __setattr__(self, name, val):
        raise ValueError("Trying to change a constant value", self)
    def __repr__(self):
        return ('{0}'.format(self.value))

dt = const(float(0.01))
print dt

then the object behaves a little more like you might expect, you can access it directly rather then '.value'

As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.

It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.

library(grid)
library(gridExtra)
library(plyr)

# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))

# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") + 
  xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category)) 
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") + 
  labs(title = "Proportion of total Frequency accounted by each Category in given Year")

# bring them together
grid.arrange(totals,proportion)

This will give you a 2 panel display like this:

If you want to add Frequency values a table is the best format.

var path = require("path");
var filepath = "C:\\Python27\\ArcGIS10.2\\python.exe";
var name = path.parse(filepath).name;
// returns
'python'

Above code returns the name of the file without extension, if you need the name with extention use

var path = require("path");
var filepath = "C:\\Python27\\ArcGIS10.2\\python.exe";
var name = path.basename(filepath);
// returns
'python.exe'

void inPlaceStrTrim(char* str) {
    int k = 0;
    int i = 0;
    for (i=0; str[i] != '\0';) {
        if (isspace(str[i])) {
            // we have got a space...
            k = i;
            for (int j=i; j<strlen(str)-1; j++) {
                str[j] = str[j+1];
            }
            str[strlen(str)-1] = '\0';
            i = k; // start the loop again where we ended..
        } else {
            i++;
        }
    }
}

Try following code

$('#ddlCodes').change(function() {
  $('#txtEntry2').val(  $('#ddlCodes :selected').text() );
});

One more way can be to use com.google.gdata.util.common.html.HtmlToText class like

MyWriter.toConsole(HtmlToText.htmlToPlainText(htmlResponse));

This is not bullet proof code though and when I run it on wikipedia entries I am getting style info also. However I believe for small/simple jobs this would be effective.

What you are looking for is probably this:

ImageView myImageView;
myImageView = mDialog.findViewById(R.id.image_id);
String src = "imageFileName"

int drawableId = this.getResources().getIdentifier(src, "drawable", context.getPackageName())
popupImageView.setImageResource(drawableId);

Let me know if this was helpful :)

You can't do it without a full CSV parser.

Please don't use any library for this effect instead use the recommended way of doing it according to Google I/O. In your recyclerView's onBindViewHolder method do this:

final boolean isExpanded = position==mExpandedPosition;
holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);
holder.itemView.setActivated(isExpanded);
holder.itemView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mExpandedPosition = isExpanded ? -1:position;
        TransitionManager.beginDelayedTransition(recyclerView);
        notifyDataSetChanged();
    }
});

• Where details is my view that will be displayed on touch (call details in your case. Default Visibility.GONE).
• mExpandedPosition is an int variable initialized to -1

And for the cool effects that you wanted, use these as your list_item attributes:

android:background="@drawable/comment_background"
android:stateListAnimator="@animator/comment_selection"

where comment_background is:

<selector
xmlns:android="http://schemas.android.com/apk/res/android"
android:constantSize="true"
android:enterFadeDuration="@android:integer/config_shortAnimTime"
android:exitFadeDuration="@android:integer/config_shortAnimTime">

<item android:state_activated="true" android:drawable="@color/selected_comment_background" />
<item android:drawable="@color/comment_background" />
</selector>

and comment_selection is:

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

<item android:state_activated="true">
    <objectAnimator
        android:propertyName="translationZ"
        android:valueTo="@dimen/z_card"
        android:duration="2000"
        android:interpolator="@android:interpolator/fast_out_slow_in" />
</item>

<item>
    <objectAnimator
        android:propertyName="translationZ"
        android:valueTo="0dp"
        android:duration="2000"
        android:interpolator="@android:interpolator/fast_out_slow_in" />
</item>
</selector>

Why not do it simply by picking eight different numbers from 0 to Horse.count and use that to get your horses?

offsets = (0...Horse.count).to_a.sample(8)
@suggested_horses = offsets.map{|i| Horse.first(:offset => i) }

This has the added advantage that it won't cause an infinite loop if you happen to have less than 8 horses in your database.

Note: Array#sample is new to 1.9 (and coming in 1.8.8), so either upgrade your Ruby, require 'backports' or use something like shuffle.first(n).

This constructor was deprecated in API level 26.1.0. use NotificationCompat.Builder(Context, String) instead. All posted Notifications must specify a NotificationChannel Id.

We should also use 'use strict' in the scope function to make sure that the code should be executed in "strict mode". Sample code shown below

(function() {
    'use strict';

    //Your code from here
})();

env: django 2.1.7

view:

dict_objs[query_obj.id] = {'obj': query_obj, 'tag': str_tag}
return render(request, 'obj.html', {'dict_objs': dict_objs})

template:

{% for obj_id,dict_obj in dict_objs.items %}
<td>{{ dict_obj.obj.obj_name }}</td>
<td style="display:none">{{ obj_id }}</td>
<td>{{ forloop.counter }}</td>
<td>{{ dict_obj.obj.update_timestamp|date:"Y-m-d H:i:s"}}</td>

If they are unsorted, you can't do much but look at each one, which is O(N), and when you're done you'll know the minimum.

Pseudo-code:

small = <biggest value> // such as std::numerical_limits<int>::max
for each element in array:
    if (element < small)
        small = element

A better way reminded by Ben to me was to just initialize small with the first element:

small = element[0]
for each element in array, starting from 1 (not 0):
    if (element < small)
        small = element

The above is wrapped in the algorithm header as std::min_element.

If you can keep your array sorted as items are added, then finding it will be O(1), since you can keep the smallest at front.

That's as good as it gets with arrays.

Prevent browser cache is not a good idea depending on the case. Looking for a solution I found solutions like this:

<link rel="stylesheet" type="text/css" href="meu.css?v=<?=filemtime($file);?>">

the problem here is that if the file is overwritten during an update on the server, which is my scenario, the cache is ignored because timestamp is modified even the content of the file is the same.

I use this solution to force browser to download assets only if its content is modified:

<link rel="stylesheet" type="text/css" href="meu.css?v=<?=hash_file('md5', $file);?>">

You can use matching groups:

p = re.compile('name (.*) is valid')

e.g.

>>> import re
>>> p = re.compile('name (.*) is valid')
>>> s = """
... someline abc
... someother line
... name my_user_name is valid
... some more lines"""
>>> p.findall(s)
['my_user_name']

Here I use re.findall rather than re.search to get all instances of my_user_name. Using re.search, you'd need to get the data from the group on the match object:

>>> p.search(s)   #gives a match object or None if no match is found
<_sre.SRE_Match object at 0xf5c60>
>>> p.search(s).group() #entire string that matched
'name my_user_name is valid'
>>> p.search(s).group(1) #first group that match in the string that matched
'my_user_name'

As mentioned in the comments, you might want to make your regex non-greedy:

p = re.compile('name (.*?) is valid')

to only pick up the stuff between 'name ' and the next ' is valid' (rather than allowing your regex to pick up other ' is valid' in your group.

pch=20 returns a symbol sized between "." and 19.

It's a filled symbol (which is probably what you want).

Aside from that, even the base graphics system in R allows a user fine-grained control over symbol size, color, and shape. E.g.,

dfx = data.frame(ev1=1:10, ev2=sample(10:99, 10), ev3=10:1)

with(dfx, symbols(x=ev1, y=ev2, circles=ev3, inches=1/3,
                  ann=F, bg="steelblue2", fg=NULL))

Adding to the above answers. Had to do one more step on Windows for git to be able to use ssh-agent.

Had to run the following command in powershell to update the environment variable:

PS> [Environment]::SetEnvironmentVariable("GIT_SSH", "$((Get-Command ssh).Source)", [System.EnvironmentVariableTarget]::User)

Restart VSCode, Powershell or whatever terminal you are using to activate the env variable.

Complete instructions can be found [here] (https://snowdrift.tech/cli/ssh/git/tutorials/2019/01/31/using-ssh-agent-git-windows.html).

Easiest way:

$(".element").fadeTo(250, 0).fadeTo(250,1).fadeTo(250,0).fadeTo(250,1);

You can repeat this as much as you want or you can use it inside a loop. the first parameter of the fadeTo() is the duration for the fade to take effect, and the second parameter is the opacity.

We can do this by setting out variable of System class in the following way

System.setOut(new PrintStream(new FileOutputStream("Path to output file"))). Also You need to close or flush 'out'(System.out.close() or System.out.flush()) variable so that you don't end up missing some output.

Guava's CharMatcher provides a concise solution:

output = CharMatcher.javaLetterOrDigit().retainFrom(input);

You can also get the 405 error if say your method is expecting a parameter and you are not passing it.

This does NOT work ( 405 error)

HTML View/Javascript

$.ajax({
         url: '/api/News',
         //.....

Web Api:

public HttpResponseMessage GetNews(int id)

Thus if the method signature is like the above then you must do:

HTML View/Javascript

$.ajax({
         url: '/api/News/5',

All answers do not work perfectly. So I created one. Below class would request layout when a new page was selected to make viewPager 's height is the current child view's height.

class WrapContentViewPager : ViewPager {
    constructor(context: Context) : super(context)
    constructor(context: Context, attrs: AttributeSet?) : super(context, attrs)

    private var curPos = 0

    init {
        addOnPageChangeListener(object : ViewPager.OnPageChangeListener {
            override fun onPageScrollStateChanged(state: Int) {}

            override fun onPageScrolled(
                position: Int,
                positionOffset: Float,
                positionOffsetPixels: Int
            ) {}

            override fun onPageSelected(position: Int) {
                curPos = position
                requestLayout()
            }
        })
    }

    override fun onMeasure(widthMeasureSpec: Int, heightMeasureSpec: Int) {
        if (childCount == 0) {
            super.onMeasure(widthMeasureSpec, heightMeasureSpec)
            return
        }
        measureChildren(widthMeasureSpec, heightMeasureSpec)
        setMeasuredDimension(measuredWidth, getChildAt(curPos).measuredHeight)
    }
}

CPU usage isn't straightforward -- java.lang.management via com.sun.management.OperatingSystemMXBean.getProcessCpuTime comes close (see Patrick's excellent code snippet above) but note that it only gives access to time the CPU spent in your process. it won't tell you about CPU time spent in other processes, or even CPU time spent doing system activities related to your process.

for instance i have a network-intensive java process -- it's the only thing running and the CPU is at 99% but only 55% of that is reported as "processor CPU".

don't even get me started on "load average" as it's next to useless, despite being the only cpu-related item on the MX bean. if only sun in their occasional wisdom exposed something like "getTotalCpuTime"...

for serious CPU monitoring SIGAR mentioned by Matt seems the best bet.

This is more a workaround than a real solution. You can create a new object test_data with another column name:

left_join("names<-"(test_data, "name"), kantrowitz, by = "name")

     name gender
1    john      M
2    bill either
3 madison      M
4    abby either
5     zzz   <NA>

To make use of regular expressions directly in Excel formulas the following UDF (user defined function) can be of help. It more or less directly exposes regular expression functionality as an excel function.

How it works

It takes 2-3 parameters.

1. A text to use the regular expression on.
2. A regular expression.
3. A format string specifying how the result should look. It can contain $0, $1, $2, and so on. $0 is the entire match, $1 and up correspond to the respective match groups in the regular expression. Defaults to $0.

Some examples

Extracting an email address:

=regex("Peter Gordon: [email protected], 47", "\w+@\w+\.\w+")
=regex("Peter Gordon: [email protected], 47", "\w+@\w+\.\w+", "$0")

Results in: [email protected]

Extracting several substrings:

=regex("Peter Gordon: [email protected], 47", "^(.+): (.+), (\d+)$", "E-Mail: $2, Name: $1")

Results in: E-Mail: [email protected], Name: Peter Gordon

To take apart a combined string in a single cell into its components in multiple cells:

=regex("Peter Gordon: [email protected], 47", "^(.+): (.+), (\d+)$", "$" & 1)
=regex("Peter Gordon: [email protected], 47", "^(.+): (.+), (\d+)$", "$" & 2)

Results in: Peter Gordon [email protected] ...

How to use

To use this UDF do the following (roughly based on this Microsoft page. They have some good additional info there!):

1. In Excel in a Macro enabled file ('.xlsm') push ALT+F11 to open the Microsoft Visual Basic for Applications Editor.
2. Add VBA reference to the Regular Expressions library (shamelessly copied from Portland Runners++ answer):
   1. Click on Tools -> References (please excuse the german screenshot)
   2. Find Microsoft VBScript Regular Expressions 5.5 in the list and tick the checkbox next to it.
   3. Click OK.

3. Click on Insert Module. If you give your module a different name make sure the Module does not have the same name as the UDF below (e.g. naming the Module Regex and the function regex causes #NAME! errors).

   

4. In the big text window in the middle insert the following:

   Function regex(strInput As String, matchPattern As String, Optional ByVal outputPattern As String = "$0") As Variant
       Dim inputRegexObj As New VBScript_RegExp_55.RegExp, outputRegexObj As New VBScript_RegExp_55.RegExp, outReplaceRegexObj As New VBScript_RegExp_55.RegExp
       Dim inputMatches As Object, replaceMatches As Object, replaceMatch As Object
       Dim replaceNumber As Integer
   
       With inputRegexObj
           .Global = True
           .MultiLine = True
           .IgnoreCase = False
           .Pattern = matchPattern
       End With
       With outputRegexObj
           .Global = True
           .MultiLine = True
           .IgnoreCase = False
           .Pattern = "\$(\d+)"
       End With
       With outReplaceRegexObj
           .Global = True
           .MultiLine = True
           .IgnoreCase = False
       End With
   
       Set inputMatches = inputRegexObj.Execute(strInput)
       If inputMatches.Count = 0 Then
           regex = False
       Else
           Set replaceMatches = outputRegexObj.Execute(outputPattern)
           For Each replaceMatch In replaceMatches
               replaceNumber = replaceMatch.SubMatches(0)
               outReplaceRegexObj.Pattern = "\$" & replaceNumber
   
               If replaceNumber = 0 Then
                   outputPattern = outReplaceRegexObj.Replace(outputPattern, inputMatches(0).Value)
               Else
                   If replaceNumber > inputMatches(0).SubMatches.Count Then
                       'regex = "A to high $ tag found. Largest allowed is $" & inputMatches(0).SubMatches.Count & "."
                       regex = CVErr(xlErrValue)
                       Exit Function
                   Else
                       outputPattern = outReplaceRegexObj.Replace(outputPattern, inputMatches(0).SubMatches(replaceNumber - 1))
                   End If
               End If
           Next
           regex = outputPattern
       End If
   End Function
   

5. Save and close the Microsoft Visual Basic for Applications Editor window.

First of all you should stop using mysql_*. MySQL supports multiple inserting like

INSERT INTO example
VALUES
  (100, 'Name 1', 'Value 1', 'Other 1'),
  (101, 'Name 2', 'Value 2', 'Other 2'),
  (102, 'Name 3', 'Value 3', 'Other 3'),
  (103, 'Name 4', 'Value 4', 'Other 4');

You just have to build one string in your foreach loop which looks like that

$values = "(100, 'Name 1', 'Value 1', 'Other 1'), (100, 'Name 1', 'Value 1', 'Other 1'), (100, 'Name 1', 'Value 1', 'Other 1')";

and then insert it after the loop

$sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) VALUES ".$values;

Another way would be Prepared Statements, which are even more suited for your situation.

This isn't quite what you're looking for, but I've found it useful in similar circumstances.

I recently added the following to my $HOME/.bashrc (something similar should be possible with shells other than bash):

if [ -f $HOME/.add-screen-to-history ] ; then
    history -s 'screen -dr'
fi

I keep a screen session running on one particular machine, and I've had problems with ssh connections to that machine being dropped, requiring me to re-run screen -dr every time I reconnect.

With that addition, and after creating that (empty) file in my home directory, I automatically have the screen -dr command in my history when my shell starts. After reconnecting, I can just type Control-P Enter and I'm back in my screen session -- or I can ignore it. It's flexible, but not quite automatic, and in your case it's easier than typing tmux list-sessions.

You might want to make the history -s command unconditional.

This does require updating your $HOME/.bashrc on each of the target systems, which might or might not make it unsuitable for your purposes.

JAVA Fax Api documentation

You could download the mac 2.2 preview release from here and unzip it.

http://www.oracle.com/technetwork/java/javafx/downloads/devpreview-1429449.html

The javadoc won't quite match 2.1, but it will be close and if you use the preview instead, it will match exactly.

I think this would help you :)

Yes, ConfigurationManager.AppSettings is available in .NET Core 2.0 after referencing NuGet package System.Configuration.ConfigurationManager.

Credits goes to @JeroenMostert for giving me the solution.

Objective-C:

NSString to NSData:

NSString* str= @"string";
NSData* data=[str dataUsingEncoding:NSUTF8StringEncoding];

NSData to NSString:

NSString* newStr = [[NSString alloc] initWithData:theData encoding:NSUTF8StringEncoding];

Swift:

String to Data:

var testString = "string"
var somedata = testString.data(using: String.Encoding.utf8)

Data to String:

var backToString = String(data: somedata!, encoding: String.Encoding.utf8) as String!
