For me the easiest way is to take all the values returned by image.shape:

height, width, channels = img.shape

if you don't want the number of channels (useful to determine if the image is bgr or grayscale) just drop the value:

height, width, _ = img.shape

Actually, I have tried the above answer, but it did not seem to work.

To get my containers to acknowledge the ulimit change, I had to update the docker.conf file before starting them:

$ sudo service docker stop
$ sudo bash -c "echo \"limit nofile 262144 262144\" >> /etc/init/docker.conf"
$ sudo service docker start

There's a similar post here: http://techpad.co.uk/content.php?sid=137 which explains how to do it.

function file_get_contents_proxy($url,$proxy){

    // Create context stream
    $context_array = array('http'=>array('proxy'=>$proxy,'request_fulluri'=>true));
    $context = stream_context_create($context_array);

    // Use context stream with file_get_contents
    $data = file_get_contents($url,false,$context);

    // Return data via proxy
    return $data;

}

git instaweb --httpd=webrick

from the git scm book

combine it with something like the approach described here for distributed development (credit to datagrok for the well described concept)

Launch a one-off git server from any local repository.

I tweeted this already but I thought it could use some expansion:

Enable decentralized git workflow: git config alias.serve "daemon --verbose --export-all --base-path=.git --reuseaddr --strict-paths .git/"

Say you use a git workflow that involves working with a core "official" repository that you pull and push your changes from and into. I'm sure many companies do this, as do many users of git hosting services like Github.

Say that server, or Github, goes down for a bit.

No worries, after all, one of the reasons you use git is so you have a copy of the entire project history in your local clone.

You can keep right on coding and committing, while you wait for the operations team to bring the server back to life. Note to self: buy doughnuts for operations team.

But what if, during this downtime, you want to collaborate with another person, who may not be a git expert, on the same repository?

Or, instead of downtime, what if you and your collaborator are in the field, and for some reason you can't get your VPN to let you connect to your official repo?

Or, what if you and your collaborator are spiking out a bunch of experimental changes, and even though you have access, you don't want to push your unfinished mess into the official central repository? (Not even as feature branches.) Maybe you're in the middle of cleaning up a disastrous rebase or merge and the branches are all over the place.

Well, git, as you are probably aware, is a "distributed" version control system.

Even though you might use a central "official" git repository in your workflow, you still have the ability to use git in a peer-to-peer manner, where you and your collaborator simply build and share commits with each other, and the central server never even has to know.

So, how do you get your branches and commits over to them, or vice versa?

• You could use git's facilities for e-mailing patches. But that's a bit inelegant and requires some knowledge on their end of how to apply e-mailed patches.
• You could create an account on your own machine for your collaborator to ssh into. But maybe you don't have local root access, or maybe you don't trust them with SSH access to your box.
• You could clone your repo onto a thumbdrive and pass it back and forth. But that's rather tedious, especially if you happen to be on the same local network, and requires a thumb drive.

You can probably think of other methods, too. But there's a super easy way: if you can see each other on the network, you can launch a one-off git server that they can use as their remote to clone, fetch, and pull your changes, and kill it when you're done with it.

The tool that enables this is git daemon, which has a lot of options and functionality, but for the purpose of enabling this easy one-off "just serve up the repo I'm in," the way to use it is to create an alias. I like to call it git serve. Run:

git config --global alias.serve "daemon --verbose --export-all --base-path=.git --reuseaddr --strict-paths .git/"

Using an alias is actually crucial, because git aliases are executed in the base directory of your working tree. So the path '.git' will always point to the right place, no matter where you are within the directory tree of your repository.

Use your new git serve like so:

1. Run git serve. "Ready to rumble," it will report. Git is bad-ass.
2. Find out your IP address. Say it's 192.168.1.123.
3. Say "hey Jane, I'm not ready/able to push these commits up to origin, but you can fetch my commits into your clone by running git fetch git://192.168.1.123/"
4. Press ctrl+c when you don't want to serve that repo any longer.

You could also tell Jane to git clone git://192.168.1.123/ local-repo-name if she does not yet have a clone of the repository. Or, use git pull git://192.168.1.123/ branchname to do a fetch and merge at once, useful if you are working together on a feature branch.

Note however that you shouldn't do this on hostile networks if you keep secrets in your repository, because there's no authentication. It doesn't advertise its existence, but anybody with a a port scanner can find it, connect to it, and clone your repo.

But it's not super dangerous because it is read-only by default. Read the git daemon man page carefully if you think that you want to enable write access. In the case where you want to obtain your collaborator's commits, it's much safer to leave it read-only, and ask your collaborator to also run this command, so you can pull from them.

Tangentially related: on the subject of one-off servers, if you want to temporarily share a bunch of static files over HTTP: python -m SimpleHTTPServer

(cd /path/to/your/special/place;/bin/your-special-command ARGS)

you can use 'use' in function like bellow example

function page_properties($objPortal) use($objPage){    
    $objPage->set_page_title($myrow['title']);
}

int

It is a primitive data type defined in C#.

It is mapped to Int32 of FCL type.

It is a value type and represent System.Int32 struct.

It is signed and takes 32 bits.

It has minimum -2147483648 and maximum +2147483647 value.

Int16

It is a FCL type.

In C#, short is mapped to Int16.

It is a value type and represent System.Int16 struct.

It is signed and takes 16 bits.

It has minimum -32768 and maximum +32767 value.

Int32

It is a FCL type.

In C#, int is mapped to Int32.

It is a value type and represent System.Int32 struct.

It is signed and takes 32 bits.

It has minimum -2147483648 and maximum +2147483647 value.

Int64

It is a FCL type.

In C#, long is mapped to Int64.

It is a value type and represent System.Int64 struct.

It is signed and takes 64 bits.

It has minimum –9,223,372,036,854,775,808 and maximum 9,223,372,036,854,775,807 value.

Also with dict

a = []
b = {1:'one'}

a.append(dict(b))
print a
b[1]='iuqsdgf'
print a

result

[{1: 'one'}]
[{1: 'one'}]

This is how I would go about it.

$posts = $this->post->orderBy('id', 'DESC')->get();

Your use of @PathParam is incorrect. It does not follow these requirements as documented in the javadoc here. I believe you just want to POST the JSON entity. You can fix this in your resource method to accept JSON entity.

@Path("/hello")
public class Hello {

  @POST
  @Produces(MediaType.APPLICATION_JSON)
  @Consumes(MediaType.APPLICATION_JSON)
  public JSONObject sayPlainTextHello(JSONObject inputJsonObj) throws Exception {

    String input = (String) inputJsonObj.get("input");
    String output = "The input you sent is :" + input;
    JSONObject outputJsonObj = new JSONObject();
    outputJsonObj.put("output", output);

    return outputJsonObj;
  }
}

And, your client code should look like this:

  ClientConfig config = new DefaultClientConfig();
  Client client = Client.create(config);
  client.addFilter(new LoggingFilter());
  WebResource service = client.resource(getBaseURI());
  JSONObject inputJsonObj = new JSONObject();
  inputJsonObj.put("input", "Value");
  System.out.println(service.path("rest").path("hello").accept(MediaType.APPLICATION_JSON).post(JSONObject.class, inputJsonObj));

I think you're just looking for the overload which takes another Collector to specify what to do with each group... and then Collectors.counting() to do the counting:

import java.util.*;
import java.util.stream.*;

class Test {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>();

        list.add("Hello");
        list.add("Hello");
        list.add("World");

        Map<String, Long> counted = list.stream()
            .collect(Collectors.groupingBy(Function.identity(), Collectors.counting()));

        System.out.println(counted);
    }
}

Result:

{Hello=2, World=1}

(There's also the possibility of using groupingByConcurrent for more efficiency. Something to bear in mind for your real code, if it would be safe in your context.)

Here's another way of doing the code above using the openpyxl module that's compatible with xlsx. From what I've seen so far, it also keeps formatting.

from openpyxl import load_workbook
wb = load_workbook('names.xlsx')
ws = wb['SheetName']
ws['A1'] = 'A1'
wb.save('names.xlsx')

How did you upload those images; via FTP or through WP uploader? You have to upload images THROUGH WP uploader in order to show them in the image library.

You can update all outdated packages like so:

brew install `brew outdated`

or

brew outdated | xargs brew install

or

brew upgrade

This is from the brew site..

for upgrading individual formula:

brew install formula-name && brew cleanup formula-name

Your data variable contains an object, not an array, and objects do not have the push function as the error states. To do what you need you can do this:

data.country = 'IN';

Or

data['country'] = 'IN';

in component:

formData.form.controls['email'].setErrors({'incorrect': true});

and in HTML:

<input mdInput placeholder="Email" type="email" name="email" required [(ngModel)]="email"  #email="ngModel">
<div *ngIf="!email.valid">{{email.errors| json}}</div>

To answer a more generic case, this error is noticed when you pick a function name which is already used in some built in library. For e.g., select.

A simple method to know about it is while compiling the file, the compiler will indicate the previous declaration.

You don't want to lose the user scaling option if you can help it. I like this JS solution from here.

<script type="text/javascript">
(function(doc) {

    var addEvent = 'addEventListener',
        type = 'gesturestart',
        qsa = 'querySelectorAll',
        scales = [1, 1],
        meta = qsa in doc ? doc[qsa]('meta[name=viewport]') : [];

    function fix() {
        meta.content = 'width=device-width,minimum-scale=' + scales[0] + ',maximum-scale=' + scales[1];
        doc.removeEventListener(type, fix, true);
    }

    if ((meta = meta[meta.length - 1]) && addEvent in doc) {
        fix();
        scales = [.25, 1.6];
        doc[addEvent](type, fix, true);
    }

}(document));
</script>

Simply restarting Visual Studio worked for me.

parameter?: type is a shorthand for parameter: type | undefined

Server side:

if (mysql_query($query)) {
    // ...
}
else {
    ajaxError(); 
}

Client side:

error: function() {
    alert("There was an error. Try again please!");
},
success: function(){
    alert("Thank you for subscribing!");
}

substring(int startIndex, int endIndex)

If you don't specify endIndex, the method will return all the characters from startIndex.

startIndex : starting index is inclusive

endIndex : ending index is exclusive

Example:

String str = "abcdefgh"

str.substring(0, 4) => abcd

str.substring(4, 6) => ef

str.substring(6) => gh

If there are multiple certificates in a pfx file (key + corresponding certificate and a CA certificate) then this command worked well for me:

certutil -importpfx c:\somepfx.pfx this works but still a password is needed to be typed in manually for private key. Including -p and "password" cause error too many arguments for certutil on XP

There's a really simple way to do this.

The problem is that .delay only effects animations, so what you need to do is make .hide() act like an animation by giving it a duration.

$("#whatever").delay().hide(1);

By giving it a nice short duration, it appears to be instant just like the regular .hide function.

This is the jQuery method. Looks like overkill but it calculates the offset.

You can use mysql_errno() for this too.

$result = mysql_query($query);

if(mysql_errno()){
    echo "MySQL error ".mysql_errno().": "
         .mysql_error()."\n<br>When executing <br>\n$query\n<br>";
}

You are casting ClientID to char* causing the function to assume its a null terinated char array, which it is not.

from cplusplus.com :

string& append ( const char * s ); Appends a copy of the string formed by the null-terminated character sequence (C string) pointed by s. The length of this character sequence is determined by the first ocurrence of a null character (as determined by traits.length(s)).

you can go to config\config.php file and remove index.php value from this variable

$config['index_page'] = 'index.php'; // delete index.php

create .htaccess file and paste this code in it.

<IfModule mod_rewrite.c>

 Options +FollowSymLinks

 RewriteEngine On
 #Send request via index.php
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d

Here is function which replaces url param with paramVal

function updateURLParameter(url, param, paramVal){
        if(!url.includes('?')){
            return url += '?' + param + '=' + paramVal;
        }else if(!url.includes(param)){
            return url += '&' + param + '=' + paramVal;
        }else {
            let paramStartIndex = url.search(param);
            let paramEndIndex = url.indexOf('&', paramStartIndex);
            if (paramEndIndex == -1){
                paramEndIndex = url.length;
            }
            let brands = url.substring(paramStartIndex, paramEndIndex);
    
            return url.replace(brands, param + '=' + paramVal);
        }
    }

You could do it like this:

The site at http://www.HTML-5.com/index.html does have the X-UA-Compatible meta tag but still goes into Compatibility View as indicated by the "torn page" icon in the address bar. How do you get the menu option to force IE 9 (Final Version 9.0.8112.16421) to render a page in Standards Mode? I tried right clicking that torn page icon as well as the "Alt" key trick to display the additional menu options mentioned by Rene Geuze, but those didn't work.

As the message have stated, you need to allow the adb access on your phone.

You need to first connect the phone to your PC with USB cables, then the authorization message will pop out on the screen. Tick remember your choice, then allow it.

IF your device doesnt shows any messages when connected to the PC.Just do this.

Remove /data/misc/adb/adb_key, reboot your phone and try connect again. The message should come up.

Here is a rough but more declarative solution. I haven't been able to get it down to a single annotation, but this seems to work well. Also not sure about performance on large data sets.

Given this JSON:

{
    "list": [
        {
            "wrapper": {
                "name": "Jack"
            }
        },
        {
            "wrapper": {
                "name": "Jane"
            }
        }
    ]
}

And these model objects:

public class RootObject {
    @JsonProperty("list")
    @JsonDeserialize(contentUsing = SkipWrapperObjectDeserializer.class)
    @SkipWrapperObject("wrapper")
    public InnerObject[] innerObjects;
}

and

public class InnerObject {
    @JsonProperty("name")
    public String name;
}

Where the Jackson voodoo is implemented like:

@Retention(RetentionPolicy.RUNTIME)
@JacksonAnnotation
public @interface SkipWrapperObject {
    String value();
}

and

public class SkipWrapperObjectDeserializer extends JsonDeserializer<Object> implements
        ContextualDeserializer {
    private Class<?> wrappedType;
    private String wrapperKey;

    public JsonDeserializer<?> createContextual(DeserializationContext ctxt,
            BeanProperty property) throws JsonMappingException {
        SkipWrapperObject skipWrapperObject = property
                .getAnnotation(SkipWrapperObject.class);
        wrapperKey = skipWrapperObject.value();
        JavaType collectionType = property.getType();
        JavaType collectedType = collectionType.containedType(0);
        wrappedType = collectedType.getRawClass();
        return this;
    }

    @Override
    public Object deserialize(JsonParser parser, DeserializationContext ctxt)
            throws IOException, JsonProcessingException {
        ObjectMapper mapper = new ObjectMapper();
        ObjectNode objectNode = mapper.readTree(parser);
        JsonNode wrapped = objectNode.get(wrapperKey);
        Object mapped = mapIntoObject(wrapped);
        return mapped;
    }

    private Object mapIntoObject(JsonNode node) throws IOException,
            JsonProcessingException {
        JsonParser parser = node.traverse();
        ObjectMapper mapper = new ObjectMapper();
        return mapper.readValue(parser, wrappedType);
    }
}

Hope this is useful to someone!

Circular imports cause problems, but Python has ways to mitigate it built-in.

The problem is when you run python a.py, it runs a.py but not mark it imported as a module. So in turn a.py -> imports module b -> imports module a -> imports module b. The last import a no-op since b is currently being imported and Python guards against that. And b is an empty module for now. So when it executes b.hi(), it can't find anything.

Note that the b.hi() that got executed is during a.py -> module b -> module a, not in a.py directly.

In your specific example, you can just run python -c 'import a' at top-level, so the first execution of a.py is registered as importing a module.

try {
    LdapContext ctx = new InitialLdapContext(env, null);
    ctx.setRequestControls(null);

    while (namingEnum.hasMore ()) {
        SearchResult result = (SearchResult) namingEnum.next ();    
        Attributes attrs = result.getAttributes ();
        System.out.println(attrs.get("cn"));

    } 
    namingEnum.close();
} catch (Exception e) {
    e.printStackTrace();
}

private SearchControls getSimpleSearchControls() {
    SearchControls searchControls = new SearchControls();
    searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE);
    searchControls.setTimeLimit(30000);
    //String[] attrIDs = {"objectGUID"};
    //searchControls.setReturningAttributes(attrIDs);
    return searchControls;
}

You could actually put a line .gitignore into your .gitignore file. This would cause the .gitignore file to be ignored by git. I do not actually think this is a good idea. I think the ignore file should be version controlled and tracked. I'm just putting this out there for completeness.

That's no problem.

@Html.Partial("../Controller/View", model)

or

@Html.Partial("~/Views/Controller/View.cshtml", model)

Should do the trick.

If you want to pass through the (other) controller, you can use:

@Html.Action("action", "controller", parameters)

or any of the other overloads

try this

 $("#vinanghinguyen_images_bbocde").attr("value", ""); 

There is a actually a setting in the VPC called "DNS Hostnames". You can modify the VPC in which the EC2 instance exists, and change this to "Yes". That should do the trick.

I ran into this issue yesterday and tried the above answer from Manny, which did not work. The VPC setting, however, did work for me.

Ultimately I added an EIP and I use that to connect.

In case anyone needs to try and merge two dataframes together on the index (instead of another column), this also works!

T1 and T2 are dataframes that have the same indices

import pandas as pd
T1 = pd.merge(T1, T2, on=T1.index, how='outer')

P.S. I had to use merge because append would fill NaNs in unnecessarily.

if ($done)
{
    header("Location: /url/to/the/other/page");
    exit;
}

break exits the loop you are in, continue starts with the next cycle of the loop immediatly.

Example:

$i = 10;
while (--$i)
{
    if ($i == 8)
    {
        continue;
    }
    if ($i == 5)
    {
        break;
    }
    echo $i . "\n";
}

will output:

9
7
6

You need to consider that GROUP BY happens after the WHERE clause conditions have been evaluated. And the WHERE clause always considers only one row, meaning that in your query, the meta_key conditions will always prevent any records from being selected, since one column cannot have multiple values for one row.

And what about the redundant meta_value checks? If a value is allowed to be both smaller and greater than a given value, then its actual value doesn't matter at all - the check can be omitted.

According to one of your comments you want to check for places less than a certain distance from a given location. To get correct distances, you'd actually have to use some kind of proper distance function (see e.g. this question for details). But this SQL should give you an idea how to start:

SELECT items.* FROM items i, meta_data m1, meta_data m2
    WHERE i.item_id = m1.item_id and i.item_id = m2.item_id
    AND m1.meta_key = 'lat' AND m1.meta_value >= 55 AND m1.meta_value <= 65
    AND m2.meta_key = 'lng' AND m2.meta_value >= 20 AND m2.meta_value <= 30

Too late for you, but for anyone else with the same question...

//a[contains(text(), 'programming')]/@href

Of course, 'programming' can be any text fragment.

You can concat many kind of expression by sorrounding your simple/complex expression between || characters:

This solution is using the official Microsoft.VisualBasic assembly to parse CSV.

Advantages:

• delimiter escaping
• ignores Header
• trim spaces
• ignore comments

Code:

    using Microsoft.VisualBasic.FileIO;

    public static List<List<string>> ParseCSV (string csv)
    {
        List<List<string>> result = new List<List<string>>();


        // To use the TextFieldParser a reference to the Microsoft.VisualBasic assembly has to be added to the project. 
        using (TextFieldParser parser = new TextFieldParser(new StringReader(csv))) 
        {
            parser.CommentTokens = new string[] { "#" };
            parser.SetDelimiters(new string[] { ";" });
            parser.HasFieldsEnclosedInQuotes = true;

            // Skip over header line.
            //parser.ReadLine();

            while (!parser.EndOfData)
            {
                var values = new List<string>();

                var readFields = parser.ReadFields();
                if (readFields != null)
                    values.AddRange(readFields);
                result.Add(values);
            }
        }

        return result;
    }

If you are using npm and browserify:

// es6 imports
import tether from 'tether';
global.Tether = tether;

// require
global.Tether = require('tether');

I think your question ultimately can be boiled down to this:

Where can I set a long-lived value that is accessible globally in my application?

The obvious answer is that it depends. What it depends on are a couple of factors:

• Will the value ever be different, or is it going to be the same for everybody?
• How long exactly is long-lived? (Forever? A Day? One browsing 'session'?)

Config

If the value is the same for everyone and will seldom change, the best place to probably put it is in a configuration file somewhere underneath app/config, e.g. app/config/companyname.php:

<?php
return [
    'somevalue' => 10,
];

You could access this value from anywhere in your application via Config::get('companyname.somevalue')

Session

If the value you are intending to store is going to be different for each user, the most logical place to put it is in Session. This is what you allude to in your question, but you are using incorrect syntax. The correct syntax to store a variable in Session is:

Session::put('somekey', 'somevalue');

The correct syntax to retrieve it back out later is:

Session::get('somekey');

As far as when to perform these operations, that's a little up to you. I would probably choose a route filter if on Laravel 4.x or Middleware if using Laravel 5. Below is an example of using a route filter that leverages another class to actually come up with the value:

// File: ValueMaker.php (saved in some folder that can be autoloaded)
class ValueMaker
{
    public function makeValue()
    {
        return 42;
    }
}

// File: app/filters.php is probably the best place
Route::filter('set_value', function() {
    $valueMaker = app()->make('ValueMaker');
    Session::put('somevalue', $valueMaker->makeValue());
});

// File: app/routes.php
Route::group(['before' => 'set_value'], function() {
   // Value has already been 'made' by this point. 
   return View::make('view')
       ->with('value', Session::get('somevalue'))
   ;
});

You can use BCEL by the Apache Software Foundation. With this tool you can generate assembler-like code, but it's Java with the BCEL API. You can learn how you can generate intermediate language code (in this case byte code).

Simple example

1. Create a Java class with this function:

   public String maxAsString(int a, int b) {
       if (a > b) {
           return Integer.valueOf(a).toString();
       } else if (a < b) {
           return Integer.valueOf(b).toString();
       } else {
           return "equals";
       }
   }
   

Now run BCELifier with this class

BCELifier bcelifier = new BCELifier("MyClass", System.out);
bcelifier.start();

You can see the result on the console for the whole class (how to build byte code MyClass.java). The code for the function is this:

private void createMethod_1() {
  InstructionList il = new InstructionList();
  MethodGen method = new MethodGen(ACC_PUBLIC, Type.STRING, new Type[] { Type.INT, Type.INT }, new String[] { "arg0", "arg1" }, "maxAsString", "MyClass", il, _cp);

  il.append(InstructionFactory.createLoad(Type.INT, 1)); // Load first parameter to address 1
  il.append(InstructionFactory.createLoad(Type.INT, 2)); // Load second parameter to adress 2
    BranchInstruction if_icmple_2 = InstructionFactory.createBranchInstruction(Constants.IF_ICMPLE, null); // Do if condition (compare a > b)
  il.append(if_icmple_2);
  il.append(InstructionFactory.createLoad(Type.INT, 1)); // Load value from address 1 into the stack
  il.append(_factory.createInvoke("java.lang.Integer", "valueOf", new ObjectType("java.lang.Integer"), new Type[] { Type.INT }, Constants.INVOKESTATIC));
  il.append(_factory.createInvoke("java.lang.Integer", "toString", Type.STRING, Type.NO_ARGS, Constants.INVOKEVIRTUAL));
  il.append(InstructionFactory.createReturn(Type.OBJECT));
  InstructionHandle ih_13 = il.append(InstructionFactory.createLoad(Type.INT, 1));
  il.append(InstructionFactory.createLoad(Type.INT, 2));
    BranchInstruction if_icmpge_15 = InstructionFactory.createBranchInstruction(Constants.IF_ICMPGE, null); // Do if condition (compare a < b)
  il.append(if_icmpge_15);
  il.append(InstructionFactory.createLoad(Type.INT, 2));
  il.append(_factory.createInvoke("java.lang.Integer", "valueOf", new ObjectType("java.lang.Integer"), new Type[] { Type.INT }, Constants.INVOKESTATIC));
  il.append(_factory.createInvoke("java.lang.Integer", "toString", Type.STRING, Type.NO_ARGS, Constants.INVOKEVIRTUAL));
  il.append(InstructionFactory.createReturn(Type.OBJECT));
  InstructionHandle ih_26 = il.append(new PUSH(_cp, "equals")); // Return "equals" string
  il.append(InstructionFactory.createReturn(Type.OBJECT));
  if_icmple_2.setTarget(ih_13);
  if_icmpge_15.setTarget(ih_26);
  method.setMaxStack();
  method.setMaxLocals();
  _cg.addMethod(method.getMethod());
  il.dispose();
}

I've always liked the BlockUI plugin: http://jquery.malsup.com/block/

It allows you to block certain elements of a page, or the entire page while an ajax request is running.

I know this is old, but it still comes up when you search for the comparison. We were using Mongo, have moved almost entirely to Dynamo, which is our first choice now. Not because it has more features, it doesn't. Mongo has a better query language, you can index within a structure, there's lots of little things. The superiority of Dynamo is in what the OP stated in his comment: it's easy. You don't have to take care of any servers. When you start to set up a Mongo sharded solution, it gets complicated. You can go to one of the hosting companies, but that's not cheap either. With Dynamo, if you need more throughput, you just click a button. You can write scripts to scale automatically. When it's time to upgrade Dynamo, it's done for you. That is all a lot of precious stress and time not spent. If you don't have dedicated ops people, Dynamo is excellent.

So we are now going on Dynamo by default. Mongo maybe, if the data structure is complicated enough to warrant it, but then we'd probably go back to a SQL database. Dynamo is obtuse, you really need to think about how you're going to build it, and likely you'll use Redis in Elasticcache to make it work for complex stuff. But it sure is nice to not have to take care of it. You code. That's it.

After careful consideration this dillema has a few different solutions:

Aggregate Everything Use an aggregate on each column to get the biggest or smallest field value. This is what I am doing since it takes 2 partially filled out records and "merges" the data.

http://sqlfiddle.com/#!3/59cde/1

SELECT
  UPPER(IDNo) AS user_id
, MAX(FirstName) AS name_first
, MAX(LastName) AS name_last
, MAX(entry) AS row_num
FROM people P
GROUP BY 
  IDNo

Get First (or Last record)

http://sqlfiddle.com/#!3/59cde/23

-- ------------------------------------------------------
-- Notes
-- entry: Auto-Number primary key some sort of unique PK is required for this method
-- IDNo:  Should be primary key in feed, but is not, we are making an upper case version
-- This gets the first entry to get last entry, change MIN() to MAX()
-- ------------------------------------------------------

SELECT 
   PC.user_id
  ,PData.FirstName
  ,PData.LastName
  ,PData.entry
FROM (
  SELECT 
      P2.user_id
     ,MIN(P2.entry) AS rownum
  FROM (
    SELECT
        UPPER(P.IDNo) AS user_id 
      , P.entry 
    FROM people P
  ) AS P2
  GROUP BY 
    P2.user_id
) AS PC
LEFT JOIN people PData
ON PData.entry = PC.rownum
ORDER BY 
   PData.entry

I like using StringBuilder with Aggregate(). The "trick" is that Append() returns the StringBuilder instance itself:

var sb = arr.Aggregate( new StringBuilder(), ( s, i ) => s.Append( i ) );
var result = sb.ToString();     

Two fixes:

1. overflow:scroll -- this makes sure your content can be seen at the cost of design (scrollbars are ugly)
2. overflow:hidden -- just cuts off any overflow. It means people can't read the content though.

If (in the SO example) you want to stop it overlapping the padding, you'd probably have to create another div, inside the padding, to hold your content.

Edit: As the other answers state, there are a variety of methods for truncating the words, be that working out the render width on the client side (never attempt to do this server-side as it will never work reliably, cross platform) through JS and inserting break-characters, or using non-standard and/or wildly incompatible CSS tags (word-wrap: break-word doesn't appear to work in Firefox).

You will always need an overflow descriptor though. If your div contains another too-wide block-type piece of content (image, table, etc), you'll need overflow to make it not destroy the layout/design.

So by all means use another method (or a combination of them) but remember to add overflow too so you cover all browsers.

Edit 2 (to address your comment below):

Start off using the CSS overflow property isn't perfect but it stops designs breaking. Apply overflow:hidden first. Remember that overflow might not break on padding so either nest divs or use a border (whatever works best for you).

This will hide overflowing content and therefore you might lose meaning. You could use a scrollbar (using overflow:auto or overflow:scroll instead of overflow:hidden) but depending on the dimensions of the div, and your design, this might not look or work great.

To fix it, we can use JS to pull things back and do some form of automated truncation. I was half-way through writing out some pseudo code for you but it gets seriously complicated about half-way through. If you need to show as much as possible, give hyphenator a look in (as mentioned below).

Just be aware that this comes at the cost of user's CPUs. It could result in pages taking a long time to load and/or resize.

The simplest way to log out and redirect back to the login or index:

<?php
    if (!isset($_SESSION)) { session_start(); }
    $_SESSION = array(); 
    session_destroy(); 
    header("Location: login.php"); // Or wherever you want to redirect
    exit();
?>

You could also do this

#include <comdef.h>

BSTR bs = SysAllocString("Hello");
std::wstring myString = _bstr_t(bs, false); // will take over ownership, so no need to free

or std::string if you prefer

EDIT: if your original string contains multiple embedded \0 this approach will not work.

Math has static method where you can call directly like Math.abs() while Date has static method like Date.now() and also instance method where you need to create new instance first var time = new Date() to call time.getHours().

// The instance method of Date can be found on `Date.prototype` so you can just call:
var keys = Object.getOwnPropertyNames(Date.prototype);

// And for the static method
var keys = Object.getOwnPropertyNames(Date);

// But if the instance already created you need to
// pass its constructor
var time = new Date();
var staticKeys = Object.getOwnPropertyNames(time.constructor);
var instanceKeys = Object.getOwnPropertyNames(time.constructor.prototype);

Of course you will need to filter the obtained keys for the static method to get actual method names, because you can also get length, name that aren't a function on the list.

But how if we want to obtain all available method from class that extend another class?
Of course you will need to scan through the root of prototype like using __proto__. For saving your time you can use script below to get static method and deep method instance.

// var keys = new Set();_x000D_
function getStaticMethods(keys, clas){_x000D_
    var keys2 = Object.getOwnPropertyNames(clas);_x000D_
_x000D_
    for(var i = 0; i < keys2.length; i++){_x000D_
        if(clas[keys2[i]].constructor === Function)_x000D_
            keys.add(keys2[i]);_x000D_
    }_x000D_
}_x000D_
_x000D_
function getPrototypeMethods(keys, clas){_x000D_
    if(clas.prototype === void 0)_x000D_
        return;_x000D_
_x000D_
    var keys2 = Object.getOwnPropertyNames(clas.prototype);_x000D_
    for (var i = keys2.length - 1; i >= 0; i--) {_x000D_
        if(keys2[i] !== 'constructor')_x000D_
            keys.add(keys2[i]);_x000D_
    }_x000D_
_x000D_
    var deep = Object.getPrototypeOf(clas);_x000D_
    if(deep.prototype !== void 0)_x000D_
        getPrototypeMethods(keys, deep);_x000D_
}_x000D_
_x000D_
// ====== Usage example ======_x000D_
// To avoid duplicate on deeper prototype we use `Set`_x000D_
var keys = new Set();_x000D_
getStaticMethods(keys, Date);_x000D_
getPrototypeMethods(keys, Date);_x000D_
_x000D_
console.log(Array.from(keys));

If you want to obtain methods from created instance, don't forget to pass the constructor of it.

I want to know the time to brute force for when the password is a dictionary word and also when it is not a dictionary word.

Dictionary password

Ballpark figure: there are about 1,000,000 English words, and if a hacker can compute about 10,000 SHA-512 hashes a second (update: see comment by CodesInChaos, this estimate is very low), 1,000,000 / 10,000 = 100 seconds. So it would take just over a minute to crack a single-word dictionary password for a single user. If the user concatenates two dictionary words, you're in the area of a few days, but still very possible if the attacker is cares enough. More than that and it starts getting tough.

Random password

If the password is a truly random sequence of alpha-numeric characters, upper and lower case, then the number of possible passwords of length N is 60^N (there are 60 possible characters). We'll do the calculation the other direction this time; we'll ask: What length of password could we crack given a specific length of time? Just use this formula:

N = Log60(t * 10,000) where t is the time spent calculating hashes in seconds (again assuming 10,000 hashes a second).

1 minute:    3.2
5 minute:    3.6
30 minutes:  4.1
2 hours:     4.4
3 days:      5.2

So given a 3 days we'd be able to crack the password if it's 5 characters long.

This is all very ball-park, but you get the idea. Update: see comment below, it's actually possible to crack much longer passwords than this.

What's going on here?

Let's clear up some misconceptions:

• The salt doesn't make it slower to calculate hashes, it just means they have to crack each user's password individually, and pre-computed hash tables (buzz-word: rainbow tables) are made completely useless. If you don't have a precomputed hash-table, and you're only cracking one password hash, salting doesn't make any difference.

• SHA-512 isn't designed to be hard to brute-force. Better hashing algorithms like BCrypt, PBKDF2 or SCrypt can be configured to take much longer to compute, and an average computer might only be able to compute 10-20 hashes a second. Read This excellent answer about password hashing if you haven't already.

• update: As written in the comment by CodesInChaos, even high entropy passwords (around 10 characters) could be bruteforced if using the right hardware to calculate SHA-512 hashes.

Notes on accepted answer:

The accepted answer as of September 2014 is incorrect and dangerously wrong:

In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don't need to find the password itself (which would be a preimage attack)... Finding a collision using a birthday attack takes O(2^n/2) time, where n is the output length of the hash function in bits.

The birthday attack is completely irrelevant to cracking a given hash. And this is in fact a perfect example of a preimage attack. That formula and the next couple of paragraphs result in dangerously high and completely meaningless values for an attack time. As demonstrated above it's perfectly possible to crack salted dictionary passwords in minutes.

The low entropy of typical passwords makes it possible that there is a relatively high chance of one of your users using a password from a relatively small database of common passwords...

That's why generally hashing and salting alone is not enough, you need to install other safety mechanisms as well. You should use an artificially slowed down entropy-enducing method such as PBKDF2 described in PKCS#5...

Yes, please use an algorithm that is slow to compute, but what is "entropy-enducing"? Putting a low entropy password through a hash doesn't increase entropy. It should preserve entropy, but you can't make a rubbish password better with a hash, it doesn't work like that. A weak password put through PBKDF2 is still a weak password.

This generator yields bytes from a file, reading the file in chunks:

def bytes_from_file(filename, chunksize=8192):
    with open(filename, "rb") as f:
        while True:
            chunk = f.read(chunksize)
            if chunk:
                for b in chunk:
                    yield b
            else:
                break

# example:
for b in bytes_from_file('filename'):
    do_stuff_with(b)

See the Python documentation for information on iterators and generators.

I tried @Aaron's solution and it didn't quite work for me, because it would re-add my keys every time I opened a new tab in my terminal. So I modified it a bit(note that most of my keys are also password-protected so I can't just send the output to /dev/null):

added_keys=`ssh-add -l`

if [ ! $(echo $added_keys | grep -o -e my_key) ]; then
    ssh-add "$HOME/.ssh/my_key"
fi

What this does is that it checks the output of ssh-add -l(which lists all keys that have been added) for a specific key and if it doesn't find it, then it adds it with ssh-add.

Now the first time I open my terminal I'm asked for the passwords for my private keys and I'm not asked again until I reboot(or logout - I haven't checked) my computer.

Since I have a bunch of keys I store the output of ssh-add -l in a variable to improve performance(at least I guess it improves performance :) )

PS: I'm on linux and this code went to my ~/.bashrc file - if you are on Mac OS X, then I assume you should add it to .zshrc or .profile

EDIT: As pointed out by @Aaron in the comments, the .zshrc file is used from the zsh shell - so if you're not using that(if you're not sure, then most likely, you're using bash instead), this code should go to your .bashrc file.

Another way to deal with this kind of problem is to use Exception().

for ii in range(200):
    try:
        for jj in range(200, 400):
            ...block0...
            if something:
                raise Exception()
    except Exception:
        continue
    ...block1...

For example:

for n in range(1,4):
    for m in range(1,4):
        print n,'-',m

result:

    1-1
    1-2
    1-3
    2-1
    2-2
    2-3
    3-1
    3-2
    3-3

Assuming we want to jump to the outer n loop from m loop if m =3:

for n in range(1,4):
    try:
        for m in range(1,4):
            if m == 3:
                raise Exception()            
            print n,'-',m
    except Exception:
        continue

result:

    1-1
    1-2
    2-1
    2-2
    3-1
    3-2

Please try window.onbeforeunload instead for window.onunload for chrome. You can also try calling onbeforeunload from the body> tag which might work in chrome.

However, we do have a problem with unload function in chrome browser. please check

location.href does not work in chrome when called through the body/window unload event

Remember if you want to give Text a backgroundcolor and then also borderRadius in that case also write overflow:'hidden' your text having a background colour will also get the radius otherwise it's impossible to achieve until unless you wrap it with View and give backgroundcolor and radius to it.

<Text style={{ backgroundColor: 'black', color:'white', borderRadius:10, overflow:'hidden'}}>Dummy</Text>

The -H 'Cache-Control: no-cache' argument is not guaranteed to work because the remote server or any proxy layers in between can ignore it. If it doesn't work, you can do it the old-fashioned way, by adding a unique querystring parameter. Usually, the servers/proxies will think it's a unique URL and not use the cache.

curl "http://www.example.com?foo123"

You have to use a different querystring value every time, though. Otherwise, the server/proxies will match the cache again. To automatically generate a different querystring parameter every time, you can use date +%s, which will return the seconds since epoch.

curl "http://www.example.com?$(date +%s)"

This is bit tricky

Now a days most of website new techniques to save websites from scraping

1st Technique

Ctrl+U this will show you Page Source

2nd Technique

This one is small hack if the website has ajax like functionality.

Just Hover the mouse key on inspect element untill whole screen becomes just right click then and copy element

That's it you are good to go.

If you are experienced with SQL Server, I would recommend ASP.NET.

ADO.NET gives you good access to SQL Server, and with SMO, you will also have just about the best access to SQL Server features. You can access SQL Server from other environments, but nothing is quite as integrated or predictable.

You can call your stored procs with SqlCommand and process the results the SqlDataReader and you'll be in business.

The best way to do this is with the sample function from the random module,

import numpy as np
import pandas as pd
from random import sample

# given data frame df

# create random index
rindex =  np.array(sample(xrange(len(df)), 10))

# get 10 random rows from df
dfr = df.ix[rindex]

You might do it this way:

function asoccArrayValueWithNumKey(&$arr, $key) {
   if (!(count($arr) > $key)) return false;
   reset($array);
   $aux   = -1;
   $found = false;
   while (($auxKey = key($array)) && !$found) {
      $aux++;
      $found = ($aux == $key);
   }
   if ($found) return $array[$auxKey];
   else return false;
}

$val = asoccArrayValueWithNumKey($array, 0);
$val = asoccArrayValueWithNumKey($array, 1);
etc...

Haven't tryed the code, but i'm pretty sure it will work.

Good luck!

I'm running SQL Server 2014 64 bit on Windows 10. I tried everything, the thing that made it work was:

EXEC sp_MSset_oledb_prop N'Microsoft.ACE.OLEDB.12.0', N'AllowInProcess', 0

I don't know why the AllowInProcess turned off makes it work but that was the key in my case. Thank you for the suggestion of turning all the options off on the linkserver.

This feature has been added in dplyr v0.3. You can now pass a named character vector to the by argument in left_join (and other joining functions) to specify which columns to join on in each data frame. With the example given in the original question, the code would be:

left_join(test_data, kantrowitz, by = c("first_name" = "name"))

also you can use "AND" instead of "OR" if you want both attributes to be applied.

select * from tickets where (assigned_to='1') and (status='open') order by created_at desc;

<input [ngModel]="item.value | currency" (ngModelChange)="item.value=$event"
name="name" type="text" />

I would like to add one more point to the accepted answer.

If the type of your input control is not text the pipe will not work.

Keep it in mind and save your time.

I had a similar issue. I've been bouncing between XCode 7 and 8 for a variety of reasons. Once you use 8 to build, you will need to use 8. I simply used Xcode 8 and applied some of the changes suggested above and it worked.

The method argument specifies the parameter of the smooth statistic. You can see stat_smooth for the list of all possible arguments to the method argument.

I think its already been answered before, but just a correction if you are populating an unordered list, the *ngFor will come in the element which you want to repeat. So it should be insdide <li>. Also, Angular2 now uses let to declare a variable.

<ul>
    <li *ngFor="let item of items; let i = index" [attr.data-index]="i">     
               {{item}}
    </li>
</ul>

use this link http://datatables.net/ref#bSortable

$(document).ready( function() {
   $('#example').dataTable( {
      "aoColumnDefs": [{ "bSortable": false, "aTargets": [ 0 ] }]
    } );
} );

The form tag needs some attributes set:

1. action: The URL that the form data is sent to on submit. Generate it with url_for. It can be omitted if the same URL handles showing the form and processing the data.
2. method="post": Submits the data as form data with the POST method. If not given, or explicitly set to get, the data is submitted in the query string (request.args) with the GET method instead.
3. enctype="multipart/form-data": When the form contains file inputs, it must have this encoding set, otherwise the files will not be uploaded and Flask won't see them.

The input tag needs a name parameter.

Add a view to handle the submitted data, which is in request.form under the same key as the input's name. Any file inputs will be in request.files.

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # your code
    # return a response

Set the form's action to that view's URL using url_for:

<form action="{{ url_for('handle_data') }}" method="post">
    <input type="text" name="projectFilepath">
    <input type="submit">
</form>

I would like to make a little bit more emphasis on some key differences between res.end() & res.send() with respect to response headers and why they are important.

1. res.send() will check the structure of your output and set header information accordingly.

    app.get('/',(req,res)=>{
       res.send('<b>hello</b>');
    });

     app.get('/',(req,res)=>{
         res.send({msg:'hello'});
     });

Where with res.end() you can only respond with text and it will not set "Content-Type"

      app.get('/',(req,res)=>{
           res.end('<b>hello</b>');
      }); 

2. res.send() will set "ETag" attribute in the response header

      app.get('/',(req,res)=>{
            res.send('<b>hello</b>');
      });

¿Why is this tag important?
The ETag HTTP response header is an identifier for a specific version of a resource. It allows caches to be more efficient, and saves bandwidth, as a web server does not need to send a full response if the content has not changed.

res.end() will NOT set this header attribute

I used CustomLayoutManager to disable RecyclerView Scrolling. Also don't use Recycler View as WrapContent, use it as 0dp, Weight=1

public class CustomLayoutManager extends LinearLayoutManager {
    private boolean isScrollEnabled;

    // orientation should be LinearLayoutManager.VERTICAL or HORIZONTAL
    public CustomLayoutManager(Context context, int orientation, boolean isScrollEnabled) {
        super(context, orientation, false);
        this.isScrollEnabled = isScrollEnabled;
    }

    @Override
    public boolean canScrollVertically() {
        //Similarly you can customize "canScrollHorizontally()" for managing horizontal scroll
        return isScrollEnabled && super.canScrollVertically();
    }
}

Use CustomLayoutManager in RecyclerView:

CustomLayoutManager mLayoutManager = new CustomLayoutManager(getBaseActivity(), CustomLayoutManager.VERTICAL, false);
        recyclerView.setLayoutManager(mLayoutManager);
        ((DefaultItemAnimator) recyclerView.getItemAnimator()).setSupportsChangeAnimations(false); 
        recyclerView.setAdapter(statsAdapter);

I use a batch file:

@ECHO OFF
SET /p comment=Comment:
git add *
git commit -a -m "%comment%"
git push

This article explains in detail how to find the reason for last startup/shutdown. In my case, this was due to windows SCCM pushing updates even though I had it disabled locally. Visit the article for full details with pictures. For reference, here are the steps copy/pasted from the website:

1. Press the Windows + R keys to open the Run dialog, type eventvwr.msc, and press Enter.

2. If prompted by UAC, then click/tap on Yes (Windows 7/8) or Continue (Vista).

3. In the left pane of Event Viewer, double click/tap on Windows Logs to expand it, click on System to select it, then right click on System, and click/tap on Filter Current Log.

4. Do either step 5 or 6 below for what shutdown events you would like to see.

5. To See the Dates and Times of All User Shut Downs of the Computer

   A) In Event sources, click/tap on the drop down arrow and check the USER32 box.

   B) In the All Event IDs field, type 1074, then click/tap on OK.

   C) This will give you a list of power off (shutdown) and restart Shutdown Type of events at the top of the middle pane in Event Viewer.

   D) You can scroll through these listed events to find the events with power off as the Shutdown Type. You will notice the date and time, and what user was responsible for shutting down the computer per power off event listed.

   E) Go to step 7.

6. To See the Dates and Times of All Unexpected Shut Downs of the Computer

   A) In the All Event IDs field, type 6008, then click/tap on OK.

   B) This will give you a list of unexpected shutdown events at the top of the middle pane in Event Viewer. You can scroll through these listed events to see the date and time of each one.

Cloning the objects before adding them. For example, instead of newList.addAll(oldList);

for(Person p : oldList) {
    newList.add(p.clone());
}

Assuming clone is correctly overriden inPerson.

Here is a comparison table:

You can view examples here.

I have created my personal batch file for this, mine is a little different but feel free to modify as you see fit. I created this a little while ago because I was bored and wanted to make a simple way for people to be able to input ending, starting, stopping, or setting to auto. This BAT file simply requests that you input the service name and it will do the rest for you. I didn't realize that he was looking for something that stated any error, I must have misread that part. Though typically this can be done by inputting >> output.txt on the end of the line.

The %var% is just a way for the user to be able to input their own service into this, instead of having to go modify the bat file every time that you want to start/stop a different service.

If I am wrong, anyone can feel free to correct me on this.

@echo off
set /p c= Would you like to start a service [Y/N]?
  if /I "%c%" EQU "Y" goto :1
  if /I "%c%" EQU "N" goto :2
    :1  
    set /p var= Service name: 
:2 
set /p c= Would you like to stop a service [Y/N]?
  if /I "%c%" EQU "Y" goto :3
  if /I "%c%" EQU "N" goto :4
    :3  
    set /p var1= Service name:
:4
set /p c= Would you like to disable a service [Y/N]?
  if /I "%c%" EQU "Y" goto :5
  if /I "%c%" EQU "N" goto :6
    :5  
    set /p var2= Service name:
:6 
set /p c= Would you like to set a service to auto [Y/N]?
  if /I "%c%" EQU "Y" goto :7
  if /I "%c%" EQU "N" goto :10
    :7  
    set /p var3= Service name:
:10
sc start %var%
sc stop %var1%
sc config %var2% start=disabled
sc config %var3% start=auto

For ordinary table markup, here's a short solution that works on all devices/browsers on BrowserStack, except IE 7 and below:

table { border-collapse: collapse; }

td + td,
th + th { border-left: 1px solid; }
tr + tr { border-top: 1px solid; }

For IE 7 support, add this:

tr + tr > td,
tr + tr > th { border-top: 1px solid; }

A test case can be seen here: http://codepen.io/dalgard/pen/wmcdE

Trying to "transfer an amount larger than my bitcoin balance" is not an unexpected error. You could use Popen.communicate() directly instead of check_output() to avoid raising an exception unnecessarily:

from subprocess import Popen, PIPE

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

variable=$(ps -ef | awk '/[p]ort 10/ {print $12}')

The [p] is a neat trick to remove the search from showing from ps

@Jeremy If you post the output of ps -ef | grep "port 10", and what you need from the line, it would be more easy to help you getting correct syntax

Year back i also faced same problem on mysql5.7 version and ibdata1 occupied 150 Gb. so i added undo tablespaces

Take Mysqldump backup
Stop mysql service
Remove all data from data dir
Add below undo tablespace parameter in current my.cnf

 #undo tablespace
  innodb_undo_directory =  /var/lib/mysql/
  innodb_rollback_segments = 128 
  innodb_undo_tablespaces = 3
  innodb_undo_logs = 128  
  innodb_max_undo_log_size=1G
  innodb_undo_log_truncate = ON

Start mysql service
store mysqldump backup

Problem resolved !!

Simply add the following:

from sys import *
path_to_current_file = sys.argv[0]
print(path_to_current_file)

Or:

from sys import *
print(sys.argv[0])

Python has support for CSV files in the eponymous csv module. It is relatively misnamed since it support much more that just comma separated values.

If you need to go beyond basic word splitting you should take a look. Say, for example, because you are in need to deal with quoted values...

To temporarily work around this problem, I found the following to be the quickest way:

export JAVA_TOOL_OPTIONS="-Xmx1024m -Xms1024m"

What I do is give each one of my reusable component a unique custom element name and then create a CSS file for that component, specifically, with all styling options for that component (and only for that component).

var MyDiv = React.createClass({
  render: function() {
    return <custom-component style={style}> Have a good and productive day! </custom-component>;
  }
});

And in file 'custom-component.css', every entry will start with the custom-component tag:

custom-component { 
   display: block; /* have it work as a div */
   color: 'white'; 
   fontSize: 200; 
} 
custom-component h1 { 
  font-size: 1.4em; 
}

That means you don't lose the critical notion of separating of concern. View vs style. If you share your component, it is easier for others to theme it to match the rest of their web page.

If you by writing "non letters and numbers" exclude more than [A-Za-z0-9] (ie. considering letters like åäö to be letters to) and want to be able to accurately handle UTF-8 strings \p{L} and \p{N} will be of aid.

1. \p{N} will match any "Number"
2. \p{L} will match any "Letter Character", which includes
   • Lower case letter
   • Modifier letter
   • Other letter
   • Title case letter
   • Upper case letter

Documentation PHP: Unicode Character Properties

$data = "Thäre!wouldn't%bé#äny";

$new_data = str_replace  ("'", "", $data);
$new_data = preg_replace ('/[^\p{L}\p{N}]/u', '_', $new_data);

var_dump (
  $new_data
);

output

string(23) "Thäre_wouldnt_bé_äny"

You may have a try for https://github.com/cls1991/pef. It will remove package with its all dependencies.

An application can read 3 types of value from the application.properties file.

application.properties

     my.name=kelly

my.dbConnection ={connection_srting:'http://localhost:...',username:'benz',password:'pwd'}

class file

@Value("${my.name}")
private String name;

@Value("#{${my.dbConnection}}")
private Map<String,String> dbValues;

If you don't have a property in application.properties then you can use default value

        @Value("${your_name : default value}")
         private String msg; 

It help to reduce lot of codes. It is occasionally used in RGB values which consist of 8bits.

where 0xff means 24(0's ) and 8(1's) like 00000000 00000000 00000000 11111111

It effectively masks the variable so it leaves only the value in the last 8 bits, and ignores all the rest of the bits

It’s seen most in cases like when trying to transform color values from a special format to standard RGB values (which is 8 bits long).

Great Explanation See here

Another GCD alternative is a barrier:

dispatch_queue_t queue = dispatch_queue_create("com.company.app.queue", DISPATCH_QUEUE_CONCURRENT);

dispatch_async(queue, ^{ 
    NSLog(@"start one!\n");  
    sleep(4);  
    NSLog(@"end one!\n");
});

dispatch_async(queue, ^{  
    NSLog(@"start two!\n");  
    sleep(2);  
    NSLog(@"end two!\n"); 
});

dispatch_barrier_async(queue, ^{  
    NSLog(@"Hi, I'm the final block!\n");  
});

Just create a concurrent queue, dispatch your two blocks, and then dispatch the final block with barrier, which will make it wait for the other two to finish.

If time_created is a unix timestamp (int), you should be able to use something like this:

DELETE FROM locks WHERE time_created < (UNIX_TIMESTAMP() - 600);

(600 seconds = 10 minutes - obviously)

Otherwise (if time_created is mysql timestamp), you could try this:

DELETE FROM locks WHERE time_created < (NOW() - INTERVAL 10 MINUTE)

Add a default constraint with the GETDATE() function as value.

ALTER TABLE myTable 
  ADD CONSTRAINT CONSTRAINT_NAME
    DEFAULT GETDATE() FOR myColumn

Doxygen or Sandcastle help file builder are the primary tools that will extract XML documentation into HTML (and other forms) of external documentation.

Note that you can combine these documentation exporters with documentation generators - as you've discovered, Resharper has some rudimentary helpers, but there are also much more advanced tools to do this specific task, such as GhostDoc (for C#/VB code with XML documentation) or my addin Atomineer Pro Documentation (for C#, C++/CLI, C++, C, VB, Java, JavaScript, TypeScript, JScript, PHP, Unrealscript code containing XML, Doxygen, JavaDoc or Qt documentation).

I feed a 514 dimensional real-valued input to a Sequential model in Keras. My model is constructed in following way :

    predictivemodel = Sequential()
    predictivemodel.add(Dense(514, input_dim=514, W_regularizer=WeightRegularizer(l1=0.000001,l2=0.000001), init='normal'))
    predictivemodel.add(Dense(257, W_regularizer=WeightRegularizer(l1=0.000001,l2=0.000001), init='normal'))
    predictivemodel.compile(loss='mean_squared_error', optimizer='adam', metrics=['accuracy'])

When I print model.summary() I get following result:

Layer (type)    Output Shape  Param #     Connected to                   
================================================================
dense_1 (Dense) (None, 514)   264710      dense_input_1[0][0]              
________________________________________________________________
activation_1    (None, 514)   0           dense_1[0][0]                    
________________________________________________________________
dense_2 (Dense) (None, 257)   132355      activation_1[0][0]               
================================================================
Total params: 397065
________________________________________________________________ 

For the dense_1 layer , number of params is 264710. This is obtained as : 514 (input values) * 514 (neurons in the first layer) + 514 (bias values)

For dense_2 layer, number of params is 132355. This is obtained as : 514 (input values) * 257 (neurons in the second layer) + 257 (bias values for neurons in the second layer)

In short, the original purpose was to make a field which will be submitted with form's submit. Sometimes, there were need to store some information in hidden field(for example, id of user) and submit it with form's submit.

From HTML September 22, 1995 specification

An INPUT element with `TYPE=HIDDEN' represents a hidden field.The user does not interact with this field; instead, the VALUE attribute specifies the value of the field. The NAME and VALUE attributes are required.

Or.. Pattern#quote:

String[] value_split = rat_values.split(Pattern.quote("|"));

This is happening because String#split accepts a regex:

| has a special meaning in regex.

quote will return a String representation for the regex.

There is no real need to create a war to run it from Tomcat. You can follow these steps

1. Create a folder in webapps folder e.g. MyApp

2. Put your html and css in that folder and name the html file, which you want to be the starting page for your application, index.html

3. Start tomcat and point your browser to url "http://localhost:8080/MyApp". Your index.html page will pop up in the browser

DataFrames and Series always have an index. Although it displays alongside the column(s), it is not a column, which is why del df['index'] did not work.

If you want to replace the index with simple sequential numbers, use df.reset_index().

To get a sense for why the index is there and how it is used, see e.g. 10 minutes to Pandas.

Simple-read but precise solution would be:

func nowAsUnixMilliseconds(){
    return time.Now().Round(time.Millisecond).UnixNano() / 1e6
}

This function:

1. Correctly rounds the value to the nearest millisecond (compare with integer division: it just discards decimal part of the resulting value);
2. Does not dive into Go-specifics of time.Duration coercion — since it uses a numerical constant that represents absolute millisecond/nanosecond divider.

P.S. I've run benchmarks with constant and composite dividers, they showed almost no difference, so feel free to use more readable or more language-strict solution.

virtualenvwrapper now lets you specify the python executable without the path.

So (on OSX at least)mkvirtualenv --python=python3 nameOfEnvironment will suffice.

If you use JSON properly, you can have nested object without any issue :

var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance 
var theUrl = "/json-handler";
xmlhttp.open("POST", theUrl);
xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
xmlhttp.send(JSON.stringify({ "email": "[email protected]", "response": { "name": "Tester" } }));

I havent tried this scenario yet - I was scared off by the (unanswered) comments below the GA announcement blog post:

https://blogs.msdn.microsoft.com/ssdt/2017/04/19/announcing-the-general-availability-ga-release-of-ssdt-17-0-april-2017/

I'll be staying on VS15 for a while ...

You can also use Uploadify, which is a great jQuery upload plugin, it let's you upload multiple files, and also style the file fields easily. http://www.uploadify.com

var reader = cmd.ExecuteReader();

var columns = new List<string>();

for(int i=0;i<reader.FieldCount;i++)
{
   columns.Add(reader.GetName(i));
}

or

var columns = Enumerable.Range(0, reader.FieldCount).Select(reader.GetName).ToList();

maybe:

import numpy as np
a=[[1,1],[2,2]]
b=np.asarray(a)
print(type(b))

output:

<class 'numpy.ndarray'>

Basically , For example :

public class Kerem
{
    public static void main(String[] args)
    {
        short x = 10;
        short y = 3;
        Object o = y;
        System.out.println(o.getClass()); // java.lang.Short
    }

}

After Xcode 6.1 Beta the code below works, slight edit on Tom S code that stopped working with the 6.1 beta (worked with previous beta):

   if UIApplication.sharedApplication().respondsToSelector("registerUserNotificationSettings:") {
        // It's iOS 8
        var types = UIUserNotificationType.Badge | UIUserNotificationType.Sound | UIUserNotificationType.Alert
       var settings = UIUserNotificationSettings(forTypes: types, categories: nil)
       UIApplication.sharedApplication().registerUserNotificationSettings(settings)
    } else {
        // It's older
        var types = UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound | UIRemoteNotificationType.Alert
        UIApplication.sharedApplication().registerForRemoteNotificationTypes(types)
    }

To sort file in place, try:

echo "$(sort your_file)" > your_file

As explained in other answers, you cannot directly redirect the output back to the input file. But you can evaluate the sort command first and then redirect it back to the original file. In this way you can implement in-place sort.

Similarly, you can also apply this trick to other command like paste to implement row-wise appending.

These are two different modes in which your computer can operate. Prior to this, when computers were like a big room, if something crashes – it halts the whole computer. So computer architects decide to change it. Modern microprocessors implement in hardware at least 2 different states.

User mode:

• mode where all user programs execute. It does not have access to RAM and hardware. The reason for this is because if all programs ran in kernel mode, they would be able to overwrite each other’s memory. If it needs to access any of these features – it makes a call to the underlying API. Each process started by windows except of system process runs in user mode.

Kernel mode:

• mode where all kernel programs execute (different drivers). It has access to every resource and underlying hardware. Any CPU instruction can be executed and every memory address can be accessed. This mode is reserved for drivers which operate on the lowest level

How the switch occurs.

The switch from user mode to kernel mode is not done automatically by CPU. CPU is interrupted by interrupts (timers, keyboard, I/O). When interrupt occurs, CPU stops executing the current running program, switch to kernel mode, executes interrupt handler. This handler saves the state of CPU, performs its operations, restore the state and returns to user mode.

Not really. GUID is more Microsoft-centric whereas UUID is used more widely (e.g., as in the urn:uuid: URN scheme, and in CORBA).

Try this:

grep -i -A 10 "my_regex"

-A 10 means, print ten lines after match to "my_regex"

android:gravity handles the alignment of its children,

android:layout_gravity handles the alignment of itself.

So use one of these.

We had a MVC application moved to a new server. .NET 4 and MVC 3 was installed, but we still got “Error 403.14". In this case, this meant that IIS did not understand that it was dealing with a MVC application, it was looking for the default page.

The solution was simple: HTTP Redirection was not installed on the server.

Server Manager – Roles – Web Server (IIS) – Roles Services – HTTP Redirection: Not installed. Installed it, problem solved.

You use:

yourcommand  > /dev/null 2>&1

If it should run in the Background add an &

yourcommand > /dev/null 2>&1 &

>/dev/null 2>&1 means redirect stdout to /dev/null AND stderr to the place where stdout points at that time

If you want stderr to occur on console and only stdout going to /dev/null you can use:

yourcommand 2>&1 > /dev/null

In this case stderr is redirected to stdout (e.g. your console) and afterwards the original stdout is redirected to /dev/null

If the program should not terminate you can use:

nohup yourcommand &

Without any parameter all output lands in nohup.out

If the second observable is hot, there is another way to do pause/resume:

var pauser = new Rx.Subject();
var source1 = Rx.Observable.interval(1000).take(1);
/* create source and pause */
var source2 = Rx.Observable.interval(1000).pausable(pauser);

source1.doOnCompleted(function () { 
  /* resume paused source2 */ 
  pauser.onNext(true);
}).subscribe(function(){
  // do something
});

source2.subscribe(function(){
  // start to recieve data 
});

Also you can use buffered version pausableBuffered to keep data during pause is on.

void htod(String hexadecimal)
{
    int h = hexadecimal.length() - 1;
    int d = 0;
    int n = 0;

    for(int i = 0; i<hexadecimal.length(); i++)
    {
        char ch = hexadecimal.charAt(i);
        boolean flag = false;
        switch(ch)
        {
            case '1': n = 1; break;
            case '2': n = 2; break;
            case '3': n = 3; break;
            case '4': n = 4; break;
            case '5': n = 5; break;
            case '6': n = 6; break;
            case '7': n = 7; break;
            case '8': n = 8; break;
            case '9': n = 9; break;
            case 'A': n = 10; break;
            case 'B': n = 11; break;
            case 'C': n = 12; break;
            case 'D': n = 13; break;
            case 'E': n = 14; break;
            case 'F': n = 15; break;
            default : flag = true;
        }
        if(flag)
        {
            System.out.println("Wrong Entry"); 
            break;
        }
        d = (int)(n*(Math.pow(16,h))) + (int)d;
        h--;
    }
    System.out.println("The decimal form of hexadecimal number "+hexadecimal+" is " + d);
}

I just wrote a parser that I called Yay! (Yaml ain't Yamlesque!) which parses Yamlesque, a small subset of YAML. So, if you're looking for a 100% compliant YAML parser for Bash then this isn't it. However, to quote the OP, if you want a structured configuration file which is as easy as possible for a non-technical user to edit that is YAML-like, this may be of interest.

It's inspred by the earlier answer but writes associative arrays (yes, it requires Bash 4.x) instead of basic variables. It does so in a way that allows the data to be parsed without prior knowledge of the keys so that data-driven code can be written.

As well as the key/value array elements, each array has a keys array containing a list of key names, a children array containing names of child arrays and a parent key that refers to its parent.

This is an example of Yamlesque:

root_key1: this is value one
root_key2: "this is value two"

drink:
  state: liquid
  coffee:
    best_served: hot
    colour: brown
  orange_juice:
    best_served: cold
    colour: orange

food:
  state: solid
  apple_pie:
    best_served: warm

root_key_3: this is value three

Here is an example showing how to use it:

#!/bin/bash
# An example showing how to use Yay

. /usr/lib/yay

# helper to get array value at key
value() { eval echo \${$1[$2]}; }

# print a data collection
print_collection() {
  for k in $(value $1 keys)
  do
    echo "$2$k = $(value $1 $k)"
  done

  for c in $(value $1 children)
  do
    echo -e "$2$c\n$2{"
    print_collection $c "  $2"
    echo "$2}"
  done
}

yay example
print_collection example

which outputs:

root_key1 = this is value one
root_key2 = this is value two
root_key_3 = this is value three
example_drink
{
  state = liquid
  example_coffee
  {
    best_served = hot
    colour = brown
  }
  example_orange_juice
  {
    best_served = cold
    colour = orange
  }
}
example_food
{
  state = solid
  example_apple_pie
  {
    best_served = warm
  }
}

And here is the parser:

yay_parse() {

   # find input file
   for f in "$1" "$1.yay" "$1.yml"
   do
     [[ -f "$f" ]] && input="$f" && break
   done
   [[ -z "$input" ]] && exit 1

   # use given dataset prefix or imply from file name
   [[ -n "$2" ]] && local prefix="$2" || {
     local prefix=$(basename "$input"); prefix=${prefix%.*}
   }

   echo "declare -g -A $prefix;"

   local s='[[:space:]]*' w='[a-zA-Z0-9_]*' fs=$(echo @|tr @ '\034')
   sed -n -e "s|^\($s\)\($w\)$s:$s\"\(.*\)\"$s\$|\1$fs\2$fs\3|p" \
          -e "s|^\($s\)\($w\)$s:$s\(.*\)$s\$|\1$fs\2$fs\3|p" "$input" |
   awk -F$fs '{
      indent       = length($1)/2;
      key          = $2;
      value        = $3;

      # No prefix or parent for the top level (indent zero)
      root_prefix  = "'$prefix'_";
      if (indent ==0 ) {
        prefix = "";          parent_key = "'$prefix'";
      } else {
        prefix = root_prefix; parent_key = keys[indent-1];
      }

      keys[indent] = key;

      # remove keys left behind if prior row was indented more than this row
      for (i in keys) {if (i > indent) {delete keys[i]}}

      if (length(value) > 0) {
         # value
         printf("%s%s[%s]=\"%s\";\n", prefix, parent_key , key, value);
         printf("%s%s[keys]+=\" %s\";\n", prefix, parent_key , key);
      } else {
         # collection
         printf("%s%s[children]+=\" %s%s\";\n", prefix, parent_key , root_prefix, key);
         printf("declare -g -A %s%s;\n", root_prefix, key);
         printf("%s%s[parent]=\"%s%s\";\n", root_prefix, key, prefix, parent_key);
      }
   }'
}

# helper to load yay data file
yay() { eval $(yay_parse "$@"); }

There is some documentation in the linked source file and below is a short explanation of what the code does.

The yay_parse function first locates the input file or exits with an exit status of 1. Next, it determines the dataset prefix, either explicitly specified or derived from the file name.

It writes valid bash commands to its standard output that, if executed, define arrays representing the contents of the input data file. The first of these defines the top-level array:

echo "declare -g -A $prefix;"

Note that array declarations are associative (-A) which is a feature of Bash version 4. Declarations are also global (-g) so they can be executed in a function but be available to the global scope like the yay helper:

yay() { eval $(yay_parse "$@"); }

The input data is initially processed with sed. It drops lines that don't match the Yamlesque format specification before delimiting the valid Yamlesque fields with an ASCII File Separator character and removing any double-quotes surrounding the value field.

 local s='[[:space:]]*' w='[a-zA-Z0-9_]*' fs=$(echo @|tr @ '\034')
 sed -n -e "s|^\($s\)\($w\)$s:$s\"\(.*\)\"$s\$|\1$fs\2$fs\3|p" \
        -e "s|^\($s\)\($w\)$s:$s\(.*\)$s\$|\1$fs\2$fs\3|p" "$input" |

The two expressions are similar; they differ only because the first one picks out quoted values where as the second one picks out unquoted ones.

The File Separator (28/hex 12/octal 034) is used because, as a non-printable character, it is unlikely to be in the input data.

The result is piped into awk which processes its input one line at a time. It uses the FS character to assign each field to a variable:

indent       = length($1)/2;
key          = $2;
value        = $3;

All lines have an indent (possibly zero) and a key but they don't all have a value. It computes an indent level for the line dividing the length of the first field, which contains the leading whitespace, by two. The top level items without any indent are at indent level zero.

Next, it works out what prefix to use for the current item. This is what gets added to a key name to make an array name. There's a root_prefix for the top-level array which is defined as the data set name and an underscore:

root_prefix  = "'$prefix'_";
if (indent ==0 ) {
  prefix = "";          parent_key = "'$prefix'";
} else {
  prefix = root_prefix; parent_key = keys[indent-1];
}

The parent_key is the key at the indent level above the current line's indent level and represents the collection that the current line is part of. The collection's key/value pairs will be stored in an array with its name defined as the concatenation of the prefix and parent_key.

For the top level (indent level zero) the data set prefix is used as the parent key so it has no prefix (it's set to ""). All other arrays are prefixed with the root prefix.

Next, the current key is inserted into an (awk-internal) array containing the keys. This array persists throughout the whole awk session and therefore contains keys inserted by prior lines. The key is inserted into the array using its indent as the array index.

keys[indent] = key;

Because this array contains keys from previous lines, any keys with an indent level grater than the current line's indent level are removed:

 for (i in keys) {if (i > indent) {delete keys[i]}}

This leaves the keys array containing the key-chain from the root at indent level 0 to the current line. It removes stale keys that remain when the prior line was indented deeper than the current line.

The final section outputs the bash commands: an input line without a value starts a new indent level (a collection in YAML parlance) and an input line with a value adds a key to the current collection.

The collection's name is the concatenation of the current line's prefix and parent_key.

When a key has a value, a key with that value is assigned to the current collection like this:

printf("%s%s[%s]=\"%s\";\n", prefix, parent_key , key, value);
printf("%s%s[keys]+=\" %s\";\n", prefix, parent_key , key);

The first statement outputs the command to assign the value to an associative array element named after the key and the second one outputs the command to add the key to the collection's space-delimited keys list:

<current_collection>[<key>]="<value>";
<current_collection>[keys]+=" <key>";

When a key doesn't have a value, a new collection is started like this:

printf("%s%s[children]+=\" %s%s\";\n", prefix, parent_key , root_prefix, key);
printf("declare -g -A %s%s;\n", root_prefix, key);

The first statement outputs the command to add the new collection to the current's collection's space-delimited children list and the second one outputs the command to declare a new associative array for the new collection:

<current_collection>[children]+=" <new_collection>"
declare -g -A <new_collection>;

All of the output from yay_parse can be parsed as bash commands by the bash eval or source built-in commands.

I'd suggest using such extension method:

public static class DataColumnCollectionExtensions
{
    public static IEnumerable<DataColumn> AsEnumerable(this DataColumnCollection source)
    {
        return source.Cast<DataColumn>();
    }
}

And therefore:

string[] columnNames = dataTable.Columns.AsEnumerable().Select(column => column.Name).ToArray();

You may also implement one more extension method for DataTable class to reduce code:

public static class DataTableExtensions
{
    public static IEnumerable<DataColumn> GetColumns(this DataTable source)
    {
        return source.Columns.AsEnumerable();
    }
}

And use it as follows:

string[] columnNames = dataTable.GetColumns().Select(column => column.Name).ToArray();

Uninstall all existing node packages. Update node and npm.As it is given in documentation as at least node v5.x.x and npm 3.x.x else it will cause errors .

Do npm clean. Then do npm install, npm start.

This solved the issue for me.

This is expected. Refer to Javadocs for split.

Splits this string around matches of the given regular expression.

This method works as if by invoking the two-argument split(java.lang.String,int) method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.

I was having the same problem with 3 of 4 inline svgs I was using, and they only disappeared (in one case, partially) on IE11.

I had <meta http-equiv="x-ua-compatible" content="ie=edge"> on the page.

In the end, the problem was extra clipping paths on the svg file. I opened the files on Illustrator, removed the clipping path (normally at the bottom of the layers) and now they're all working.

Simple! Throw this at the like, bottom of your CSS file and this part of the CSS will be modified within a phone: -

/* ON A PHONE */
@media only screen and (max-width: 600px) { /* CSS HERE ONLY ON PHONE */ }

And voila!

In Java 8, there is a new Date/Time API JSR 310 that is more sane. The spec lead is the same as the primary author of JodaTime and they share many similar concepts and patterns.

To tackle this with vanilla CSS look for patterns in the ancestors of the h1..h6 elements:

<section class="row">
  <header>
    <h1>AMD RX Series</h1>
    <small>These come in different brands and types</small>
  </header>
</header>

<div class="row">
  <h3>Sapphire RX460 OC 2/4GB</h3>
  <small>Available in 2GB and 4GB models</small>
</div>

If you can spot patterns you may be able to write a selector which targets what you want. Given the above example all h1..h6 elements may be targeted by combining the :first-child and :not pseudo-classes from CSS3, available in all modern browsers, like so:

.row :first-child:not(header) { /* ... */ }

In the future advanced pseudo-class selectors like :has(), and subsequent-sibling combinators (~), will provide even more control as Web standards continue to evolve over time.

The error can be caused by mixing together debug builds and release builds in same executable or dll.

1. in the vs configuration manager, are some of your projects in debug mode and some in release mode?
2. is one of your release projects has the preprocessor symbol DEBUG or _DEBUG defined?
3. is one of your debug projects has the preprocessor symbol NDEBUG defined?

The iterator_facade documentation from Boost.Iterator provides what looks like a nice tutorial on implementing iterators for a linked list. Could you use that as a starting point for building a random-access iterator over your container?

If nothing else, you can take a look at the member functions and typedefs provided by iterator_facade and use it as a starting point for building your own.

The trick is to read the declaration backwards (right-to-left):

const int a = 1; // read as "a is an integer which is constant"
int const a = 1; // read as "a is a constant integer"

Both are the same thing. Therefore:

a = 2; // Can't do because a is constant

The reading backwards trick especially comes in handy when you're dealing with more complex declarations such as:

const char *s;      // read as "s is a pointer to a char that is constant"
char c;
char *const t = &c; // read as "t is a constant pointer to a char"

*s = 'A'; // Can't do because the char is constant
s++;      // Can do because the pointer isn't constant
*t = 'A'; // Can do because the char isn't constant
t++;      // Can't do because the pointer is constant

Print lines where the third field is either snow or snowman only:

awk '$3~/^snow(man)?$/' file

The linked list holds operations on the shared data structure.

For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).

In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.

In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.

I tried this code, to retrieve shared preferences from an activity, and could not get it to work:

        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
    sharedPreferences.getAll();
    Log.d("AddNewRecord", "getAll: " + sharedPreferences.getAll());
    Log.d("AddNewRecord", "Size: " + sharedPreferences.getAll().size());

Every time I tried, my preferences returned 0, even though I have 14 preferences saved by the preference activity. I finally found the answer. I added this to the preferences in the onCreate section.

getPreferenceManager().setSharedPreferencesName("defaultPreferences");

After I added this statement, my saved preferences returned as expected. I hope that this helps someone else who may experience the same issue that I did.

To avoid this problem you can use native method Bitmap.recycle() before null-ing Bitmap object (or setting another value). Example:

public final void setMyBitmap(Bitmap bitmap) {
  if (this.myBitmap != null) {
    this.myBitmap.recycle();
  }
  this.myBitmap = bitmap;
}

And next you can change myBitmap w/o calling System.gc() like:

setMyBitmap(null);    
setMyBitmap(anotherBitmap);

java.util.Date date = ...
DateTime dateTime = new DateTime(date);

Make sure date isn't null, though, otherwise it acts like new DateTime() - I really don't like that.

This boils down to a difference between definitions and declarations.

• You can declare functions and variables multiple times, in different translation units, or in the same translation unit. Once you declare a function or a variable, you can use it from that point on.
• You can define a non-static function or a variable only once in all of your translation units. Defining non-static items more than once causes linker errors.

Headers generally contain declarations; cpp files contain definitions. When you include a file with definitions more than once, you get duplicates during linking.

In your situation one defintion comes from foo.cpp, and the other definition comes from main.cpp, which includes foo.cpp.

Note: if you change foo to be static, you would have no linking errors. Despite the lack of errors, this is not a good thing to do.

.item:hover img 
{
 -moz-transform: scale(1.3);
 -webkit-transform: scale(1.3);
 transform: scale(1.3);
}

this way you can zoom any image with simple animation. If you need a complete tutorial here is a official tutorial: http://talkerscode.com/webtricks/image-zoom-in-on-hover-using-css3.php

To change working directory in GitMSYS's Git Bash you can just use cd

cd /path/do/directory

Note that:

• Directory separators use the forward-slash (/) instead of backslash.
• Drives are specified with a lower case letter and no colon, e.g. "C:\stuff" should be represented with "/c/stuff".
• Spaces can be escaped with a backslash (\)
• Command line completion is your friend. Press TAB at anytime to expand stuff, including Git options, branches, tags, and directories.

Also, you can right click in Windows Explorer on a directory and "Git Bash here".

Use Select-Object (whose alias is select) with the -Unique switch; e.g.:

$a = @(1,2,3,4,5,5,6,7,8,9,0,0)
$a = $a | select -Unique

The best and easy way for image resize using Java Swing is:

jLabel.setIcon(new ImageIcon(new javax.swing.ImageIcon(getClass().getResource("/res/image.png")).getImage().getScaledInstance(200, 50, Image.SCALE_SMOOTH)));

For better display, identify the actual height & width of image and resize based on width/height percentage

There are, in my opinion, three great python testing frameworks that are good to check out.
unittest - module comes standard with all python distributions
nose - can run unittest tests, and has less boilerplate.
pytest - also runs unittest tests, has less boilerplate, better reporting, lots of cool extra features

To get a good comparison of all of these, read through the introductions to each at http://pythontesting.net/start-here.
There's also extended articles on fixtures, and more there.

I have also faced this issue when my window service started throwing the exception

System.UnauthorizedAccessException: Access to the path "C:\\Order\\Media
44aa4857-3bac-4a18-a307-820450361662.mp4" is denied.

So as a solution, I checked the user account associated with my service, as shown in below screen capture

So in my case it was NETWORK SERVICE

And then went to the folder properties to check if the associated user account also exists under their permission tab. It was missing in my case and when I added it and it fixed my issue.

For more information please check the below screen capture

you should try this

npm forever

https://www.npmjs.com/package/forever

Depending on your definition of shortly, you could use one of the following options:

• try: int(your_input); except ValueError: # ...
• your_input.isdigit()
• use a regex
• use parse which is kind of the opposite of format

I had given permissions I shouldn't have to write in some folders (especially /usr/bin/), and that caused the problem. I fixed it by opening Disk Utility and running 'Repair Disk Permissions' on the Macintosh HD disk.

Why answer a 6 year old question ?
One the most fundamental concepts working with any programming language is how to navigate from one (window, form or page) to another. Also while doing this navigation the developer often wants to pass data from one (window, form or page) and display or use the data passed
While most of the answers here provide good to excellent examples how to accomplish this we thought we would kick it up a notch or two or three
We said three because we will navigate between three (window, form or page) and use the concept of static variables to pass data around the (window, form or page)
We will also include some decision making code while we navigate

To compare entire revisions, it's simply:

svn diff -r 8979:11390

If you want to compare the last committed state against your currently saved working files, you can use convenience keywords:

svn diff -r PREV:HEAD

(Note, without anything specified afterwards, all files in the specified revisions are compared.)

You can compare a specific file if you add the file path afterwards:

svn diff -r 8979:HEAD /path/to/my/file.php

Here is an example showing some text in circles with data from a json file: http://bl.ocks.org/4474971. Which gives the following:

The main idea behind this is to encapsulate the text and the circle in the same "div" as you would do in html to have the logo and the name of the company in the same div in a page header.

The main code is:

var width = 960,
    height = 500;

var svg = d3.select("body").append("svg")
    .attr("width", width)
    .attr("height", height)

d3.json("data.json", function(json) {
    /* Define the data for the circles */
    var elem = svg.selectAll("g")
        .data(json.nodes)

    /*Create and place the "blocks" containing the circle and the text */  
    var elemEnter = elem.enter()
        .append("g")
        .attr("transform", function(d){return "translate("+d.x+",80)"})

    /*Create the circle for each block */
    var circle = elemEnter.append("circle")
        .attr("r", function(d){return d.r} )
        .attr("stroke","black")
        .attr("fill", "white")

    /* Create the text for each block */
    elemEnter.append("text")
        .attr("dx", function(d){return -20})
        .text(function(d){return d.label})
})

and the json file is:

{"nodes":[
  {"x":80, "r":40, "label":"Node 1"}, 
  {"x":200, "r":60, "label":"Node 2"}, 
  {"x":380, "r":80, "label":"Node 3"}
]}

The resulting html code shows the encapsulation you want:

<svg width="960" height="500">
    <g transform="translate(80,80)">
        <circle r="40" stroke="black" fill="white"></circle>
        <text dx="-20">Node 1</text>
    </g>
    <g transform="translate(200,80)">
        <circle r="60" stroke="black" fill="white"></circle>
        <text dx="-20">Node 2</text>
    </g>
    <g transform="translate(380,80)">
        <circle r="80" stroke="black" fill="white"></circle>
        <text dx="-20">Node 3</text>
    </g>
</svg>

There's not always an updater between versions, depending on the version you're starting from and what you're updating to. If that happens, download the full installer and reinstall Android Studio.

Could you not have simply added:

align-items:center;

to a new class in your row div. Essentially:

<div class="row align_center">

.align_center { align-items:center; }

A standard-lib version (no pandas)

This assumes that the first row of the csv is the headers

import csv

# open the file in universal line ending mode 
with open('test.csv', 'rU') as infile:
  # read the file as a dictionary for each row ({header : value})
  reader = csv.DictReader(infile)
  data = {}
  for row in reader:
    for header, value in row.items():
      try:
        data[header].append(value)
      except KeyError:
        data[header] = [value]

# extract the variables you want
names = data['name']
latitude = data['latitude']
longitude = data['longitude']

For pipeline:

pipeline {
  environment {
     BRANCH_NAME = "${GIT_BRANCH.split("/")[1]}"
  }
}

[updating in response to more details in the edited question]

The problem you're running into is that, once a page is modified by ajax requests, the current HTML exists only inside the browser's DOM-- there's no longer any independent source HTML that you can validate other than what you can pull out of the DOM.

As you've observed, IE's DOM stores tags in upper case, fixes up unclosed tags, and makes lots of other alterations to the HTML it got originally. This is because browsers are generally very good at taking HTML with problems (e.g. unclosed tags) and fixing up those problems to display something useful to the user. Once the HTML has been canonicalized by IE, the original source HTML is essentially lost from the DOM's perspective, as far as I know.

Firefox most likley makes fewer of these changes, so Firebug is probably your better bet.

A final (and more labor-intensive) option may work for pages with simple ajax alterations, e.g. fetching some HTML from the server and importing this into the page inside a particular element. In that case, you can use fiddler or similar tool to manually stitch together the original HTML with the Ajax HTML. This is probably more trouble than it's worth, and is error prone, but it's one more possibility.

[Original response here to the original question]

Fiddler (http://www.fiddlertool.com/) is a free, browser-independent tool which works very well to fetch the exact HTML received by a browser. It shows you exact bytes on the wire as well as decoded/unzipped/etc content which you can feed into any HTML analysis tool. It also shows headers, timings, HTTP status, and lots of other good stuff.

You can also use fiddler to copy and rebuild requests if you want to test how a server responds to slightly different headers.

Fiddler works as a proxy server, sitting in between your browser and the website, and logs traffic going both ways.

You are most likely pushing a string 'NULL' to the table, rather then an actual NULL, but other things may be going on as well, an illustration:

mysql> CREATE TABLE date_test (pdd DATE NOT NULL);
Query OK, 0 rows affected (0.11 sec)

mysql> INSERT INTO date_test VALUES (NULL);

https://docs.oracle.com/javase/tutorial/reflect/class/classMembers.html also has charts for locating methods and constructors.

In a nutshell, the syntax for Bower version numbers (and NPM's) is called SemVer, which is short for 'Semantic Versioning'. You can find documentation for the detailed syntax of SemVer as used in Bower and NPM on the API for the semver parser within Node/npm. You can learn more about the underlying spec (which does not mention ~ or other syntax details) at semver.org.

There's a super-handy visual semver calculator you can play with, making all of this much easier to grok and test.

SemVer isn't just a syntax! It has some pretty interesting things to say about the right ways to publish API's, which will help to understand what the syntax means. Crucially:

Once you identify your public API, you communicate changes to it with specific increments to your version number. Consider a version format of X.Y.Z (Major.Minor.Patch). Bug fixes not affecting the API increment the patch version, backwards compatible API additions/changes increment the minor version, and backwards incompatible API changes increment the major version.

So, your specific question about ~ relates to that Major.Minor.Patch schema. (As does the related caret operator ^.) You can use ~ to narrow the range of versions you're willing to accept to either:

• subsequent patch-level changes to the same minor version ("bug fixes not affecting the API"), or:
• subsequent minor-level changes to the same major version ("backwards compatible API additions/changes")

For example: to indicate you'll take any subsequent patch-level changes on the 1.2.x tree, starting with 1.2.0, but less than 1.3.0, you could use:

"angular": "~1.2"
  or:
"angular": "~1.2.0"

This also gets you the same results as using the .x syntax:

"angular": "1.2.x"

But, you can use the tilde/~ syntax to be even more specific: if you're only willing to accept patch-level changes starting with 1.2.4, but still less than 1.3.0, you'd use:

"angular": "~1.2.4"

Moving left, towards the major version, if you use...

"angular": "~1"

... it's the same as...

"angular": "1.x"
  or:
"angular": "^1.0.0"

...and matches any minor- or patch-level changes above 1.0.0, and less than 2.0:

Note that last variation above: it's called a 'caret range'. The caret looks an awful lot like a >, so you'd be excused for thinking it means "any version greater than 1.0.0". (I've certainly slipped on that.) Nope!

Caret ranges are basically used to say that you care only about the left-most significant digit - usually the major version - and that you'll permit any minor- or patch-level changes that don't affect that left-most digit. Yet, unlike a tilde range that specifies a major version, caret ranges let you specify a precise minor/patch starting point. So, while ^1.0.0 === ~1, a caret range such as ^1.2.3 lets you say you'll take any changes >=1.2.3 && <2.0.0. You couldn't do that with a tilde range.

That all seems confusing at first, when you look at it up-close. But zoom out for a sec, and think about it this way: the caret simply lets you say that you're most concerned about whatever significant digit is left-most. The tilde lets you say you're most concerned about whichever digit is right-most. The rest is detail.

It's the expressive power of the tilde and the caret that explains why people use them much more than the simpler .x syntax: they simply let you do more. That's why you'll see the tilde used often even where .x would serve. As an example, see npm itself: its own package.json file includes lots of dependencies in ~2.4.0 format, rather than the 2.4.x format it could use. By sticking to ~, the syntax is consistent all the way down a list of 70+ versioned dependencies, regardless of which beginning patch number is acceptable.

Anyway, there's still more to SemVer, but I won't try to detail it all here. Check it out on the node semver package's readme. And be sure to use the semantic versioning calculator while you're practicing and trying to get your head around how SemVer works.

RE: Non-Consecutive Version Numbers: OP's final question seems to be about specifying non-consecutive version numbers/ranges (if I have edited it fairly). Yes, you can do that, using the common double-pipe "or" operator: ||. Like so:

"angular": "1.2 <= 1.2.9 || >2.0.0"

To have newline in code you use _

Example:

Dim a As Integer
a = 500 _
  + 80 _
  + 90

MsgBox a

There are two ways. the first is to completely refresh the page using typical form submission

//your_page.php

<?php 

$saveSuccess = null;
$saveMessage = null;

if($_SERVER['REQUEST_METHOD'] == 'POST') {
  // if form has been posted process data

  // you dont need the addContact function you jsut need to put it in a new array
  // and it doesnt make sense in this context so jsut do it here
  // then used json_decode and json_decode to read/save your json in
  // saveContact()
  $data = array(
    'fullname' = $_POST['fullname'],
    'email' => $_POST['email'],
    'phone' => $_POST['phone']
  );

  // always return true if you save the contact data ok or false if it fails
  if(($saveSuccess = saveContact($data)) {
     $saveMessage = 'Your submission has been saved!';     
  } else {
     $saveMessage = 'There was a problem saving your submission.';
  } 
}
?>

<!-- your other html -->

<?php if($saveSuccess !== null): ?>
   <p class="flash_message"><?php echo $saveMessage ?></p>
<?php endif; ?>

<form action="your_page.php" method="post">
    <fieldset>
        <legend>Add New Contact</legend>
        <input type="text" name="fullname" placeholder="First name and last name" required /> <br />
        <input type="email" name="email" placeholder="[email protected]" required /> <br />
        <input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /> <br />
        <input type="submit" name="submit" class="button" value="Add Contact" onClick="" />
        <input type="button" name="cancel" class="button" value="Reset" />
    </fieldset>
</form>

<!-- the rest of your HTML -->

The second way would be to use AJAX. to do that youll want to completely seprate the form processing into a separate file:

// process.php

$response = array();

if($_SERVER['REQUEST_METHOD'] == 'POST') {
  // if form has been posted process data

  // you dont need the addContact function you jsut need to put it in a new array
  // and it doesnt make sense in this context so jsut do it here
  // then used json_decode and json_decode to read/save your json in
  // saveContact()
  $data = array(
    'fullname' => $_POST['fullname'],
    'email' => $_POST['email'],
    'phone' => $_POST['phone']
  );

  // always return true if you save the contact data ok or false if it fails
  $response['status'] = saveContact($data) ? 'success' : 'error';
  $response['message'] = $response['status']
      ? 'Your submission has been saved!'
      : 'There was a problem saving your submission.';

  header('Content-type: application/json');
  echo json_encode($response);
  exit;
}
?>

And then in your html/js

<form id="add_contact" action="process.php" method="post">
        <fieldset>
            <legend>Add New Contact</legend>
            <input type="text" name="fullname" placeholder="First name and last name" required /> <br />
            <input type="email" name="email" placeholder="[email protected]" required /> <br />
            <input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /> <br />
            <input id="add_contact_submit" type="submit" name="submit" class="button" value="Add Contact" onClick="" />
            <input type="button" name="cancel" class="button" value="Reset" />
        </fieldset>
    </form>
    <script type="text/javascript">
     $(function(){
         $('#add_contact_submit').click(function(e){
            e.preventDefault();  
            $form = $(this).closest('form');

            // if you need to then wrap this ajax call in conditional logic

            $.ajax({
              url: $form.attr('action'),
              type: $form.attr('method'),
              dataType: 'json',
              success: function(responseJson) {
                 $form.before("<p>"+responseJson.message+"</p>");
              },
              error: function() {
                 $form.before("<p>There was an error processing your request.</p>");
              }
            });
         });         
     });
    </script>

I did not find where the .rnd file is so I ran the cmd as administrator and it worked like a charm.

Try this in the console:

JSON.parse(undefined)

Here is what you will get:

Uncaught SyntaxError: Unexpected token u in JSON at position 0
    at JSON.parse (<anonymous>)
    at <anonymous>:1:6

In other words, your app is attempting to parse undefined, which is not valid JSON.

There are two common causes for this. The first is that you may be referencing a non-existent property (or even a non-existent variable if not in strict mode).

window.foobar = '{"some":"data"}';
JSON.parse(window.foobarn)  // oops, misspelled!

The second common cause is failure to receive the JSON in the first place, which could be caused by client side scripts that ignore errors and send a request when they shouldn't.

Make sure both your server-side and client-side scripts are running in strict mode and lint them using ESLint. This will give you pretty good confidence that there are no typos.

Referencing Steven Penny's answer, it's best to create a test branch and test the PR. So here's what you would do.

1. Create a test branch to merge the PR into locally. Assuming you're on the master branch:

git checkout -b test

2. Get the PR changes into the test branch

git pull origin pull/939/head:test

Now, you can safely test the changes on this local test branch (in this case, named test) and once you're satisfied, can merge it as usual from GitHub.

You can manually force disconnection by a Thread sleep. This is an example:

URLConnection con = url.openConnection();
con.setConnectTimeout(5000);
con.setReadTimeout(5000);
new Thread(new InterruptThread(con)).start();

then

public class InterruptThread implements Runnable {

    HttpURLConnection con;
    public InterruptThread(HttpURLConnection con) {
        this.con = con;
    }

    public void run() {
        try {
            Thread.sleep(5000); // or Thread.sleep(con.getConnectTimeout())
        } catch (InterruptedException e) {

        }
        con.disconnect();
        System.out.println("Timer thread forcing to quit connection");
    }
}

dt = dt.AsEnumerable().GroupBy(r => r.Field<int>("ID")).Select(g => g.First()).CopyToDataTable();

You can fix this easily with jQuery - and a little ugly hack :-)

I have a asp.net page with a ReportViewer user control.

 <rsweb:ReportViewer ID="ReportViewer1" runat="server"...

In the document ready event I then start a timer and look for the element which needs the overflow fix (as previous posts):

 <script type="text/javascript">
    $(function () {
        // Bug-fix on Chrome and Safari etc (webkit)
        if ($.browser.webkit) {
            // Start timer to make sure overflow is set to visible
             setInterval(function () {
                var div = $('#<%=ReportViewer1.ClientID %>_fixedTable > tbody > tr:last > td:last > div')
                div.css('overflow', 'visible');
            }, 1000);
        }
    });
</script>

Better than assuming it has a certain id. You can adjust the timer to whatever you like. I set it to 1000 ms here.

Check with your bean class. Column data type and bean datatype must be same.

Execute the GetEventIdsByEventDate() method and save the results in a variable, and then you can use the .Contains() method

The font sizes in your question are an example of what ratio each header should be in comparison to each other, rather than what size they should be themselves (in pixels).

So in response to your question "Is there a 'best practice' for these for mobile phones? - say iphone screen size?", yes there probably is - but you might find what someone says is "best practice" does not work for your layout.

However, to help get you on the right track, this article about building responsive layouts provides a good example of how to calculate the base font-size in pixels in relation to device screen sizes.

The suggested font-sizes for screen resolutions suggested from that article are as follows:

@media (min-width: 858px) {
    html {
        font-size: 12px;
    }
}

@media (min-width: 780px) {
    html {
        font-size: 11px;
    }
}

@media (min-width: 702px) {
    html {
        font-size: 10px;
    }
}

@media (min-width: 724px) {
    html {
        font-size: 9px;
    }
}

@media (max-width: 623px) {
    html {
        font-size: 8px;
    }
}

Padding by definition is a positive integer (including 0).

Negative padding would cause the border to collapse into the content (see the box-model page on w3) - this would make the content area smaller than the content, which doesn't make sense.

Run the following commands in guest machine/VM:

wget https://raw.githubusercontent.com/mitchellh/vagrant/master/keys/vagrant.pub -O ~/.ssh/authorized_keys
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
chown -R vagrant:vagrant ~/.ssh

Then do vagrant halt. This will remove and regenerate your private keys.

(These steps assume you have already created or already have the ~/.ssh/ and ~/.ssh/authorized_keys directories under your home folder.)

Want to put out there that there is not much to worry about if someone provides an answer as an extension method because an extension method is just a cool way to call an instance method. I understand that you want the answer without using an extension method. Regardless if the method is defined as static, instance or extension - the result is the same.

The code below uses the code from the accepted answer to define an extension method and an instance method and creates a unit test to show the output is the same.

public static class Extensions
{
    public static void Each<T>(this IEnumerable<T> items, Action<T> action)
    {
        foreach (var item in items)
        {
            action(item);
        }
    }
}

[TestFixture]
public class ForEachTests
{
    public void Each<T>(IEnumerable<T> items, Action<T> action)
    {
        foreach (var item in items)
        {
            action(item);
        }
    }

    private string _extensionOutput;

    private void SaveExtensionOutput(string value)
    {
        _extensionOutput += value;
    }

    private string _instanceOutput;

    private void SaveInstanceOutput(string value)
    {
        _instanceOutput += value;
    }

    [Test]
    public void Test1()
    {
        string[] teams = new string[] {"cowboys", "falcons", "browns", "chargers", "rams", "seahawks", "lions", "heat", "blackhawks", "penguins", "pirates"};

        Each(teams, SaveInstanceOutput);

        teams.Each(SaveExtensionOutput);

        Assert.AreEqual(_extensionOutput, _instanceOutput);
    }
}

Quite literally, the only thing you need to do to convert an extension method to an instance method is remove the static modifier and the first parameter of the method.

This method

public static void Each<T>(this IEnumerable<T> items, Action<T> action)
{
    foreach (var item in items)
    {
        action(item);
    }
 }

becomes

public void Each<T>(Action<T> action)
{
    foreach (var item in items)
    {
        action(item);
    }
 }

I was initially running:

sudo scp

Once I ran just scp, without sudo, it copied everything fine:

scp

It seems to me that sudo scp command wasn't reading my current user's SSH public key at ~/.ssh/id_rsa.pub.

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

Here is a bash script for newer Maven copy and paste it...

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

TL;DR

Summary; if you have binary (non-alphanumeric) data (or a significantly sized payload) to transmit, use multipart/form-data. Otherwise, use application/x-www-form-urlencoded.

The MIME types you mention are the two Content-Type headers for HTTP POST requests that user-agents (browsers) must support. The purpose of both of those types of requests is to send a list of name/value pairs to the server. Depending on the type and amount of data being transmitted, one of the methods will be more efficient than the other. To understand why, you have to look at what each is doing under the covers.

For application/x-www-form-urlencoded, the body of the HTTP message sent to the server is essentially one giant query string -- name/value pairs are separated by the ampersand (&), and names are separated from values by the equals symbol (=). An example of this would be: 

MyVariableOne=ValueOne&MyVariableTwo=ValueTwo

According to the specification:

[Reserved and] non-alphanumeric characters are replaced by `%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character

That means that for each non-alphanumeric byte that exists in one of our values, it's going to take three bytes to represent it. For large binary files, tripling the payload is going to be highly inefficient.

That's where multipart/form-data comes in. With this method of transmitting name/value pairs, each pair is represented as a "part" in a MIME message (as described by other answers). Parts are separated by a particular string boundary (chosen specifically so that this boundary string does not occur in any of the "value" payloads). Each part has its own set of MIME headers like Content-Type, and particularly Content-Disposition, which can give each part its "name." The value piece of each name/value pair is the payload of each part of the MIME message. The MIME spec gives us more options when representing the value payload -- we can choose a more efficient encoding of binary data to save bandwidth (e.g. base 64 or even raw binary).

Why not use multipart/form-data all the time? For short alphanumeric values (like most web forms), the overhead of adding all of the MIME headers is going to significantly outweigh any savings from more efficient binary encoding.
