to be super duper ))

 fun rnd_int(min: Int, max: Int): Int {
        var max = max
        max -= min
        return (Math.random() * ++max).toInt() + min
    }

Just an addition to the previous answers. Let's not forget that when dealing with real data there might be null values, so it's useful to also include those in the counting by using the option dropna=False (default is True)

An example:

>>> df['Embarked'].value_counts(dropna=False)
S      644
C      168
Q       77
NaN      2

Here comes the improved and recursive version of AgileJon's solution (demo):

function loopThrough(obj){
  for(var key in obj){
    // skip loop if the property is from prototype
    if(!obj.hasOwnProperty(key)) continue;

    if(typeof obj[key] !== 'object'){
      //your code
      console.log(key+" = "+obj[key]);
    } else {
      loopThrough(obj[key]);
    }
  }
}
loopThrough(validation_messages);

This solution works for all kinds of different depths.

You can enable pretty-printing by setting the SerializationFeature.INDENT_OUTPUT on your ObjectMapper like so:

mapper.enable(SerializationFeature.INDENT_OUTPUT);

One interesting way is by using array_keys():

foreach (array_keys($messages, 401, true) as $key) {
    unset($messages[$key]);
}

The array_keys() function takes two additional parameters to return only keys for a particular value and whether strict checking is required (i.e. using === for comparison).

This can also remove multiple array items with the same value (e.g. [1, 2, 3, 3, 4]).

I use this to get the Parent, similarly for child

$( this ).children( 'li.target' ).css("border", "3px double red");

Good Luck

After :

sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0) 
    error("ERROR opening socket");

You can add (with standard C99 compound literal support) :

if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &(int){1}, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

Or :

int enable = 1;
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &enable, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

As I understand it, "request timeout" means the ICMP packet reached from one host to the other host but the reply could not reach the requesting host. There may be more packet loss or some physical issue. "destination host unreachable" means there is no proper route defined between two hosts.

My suggestion:

$http({
    method: 'DELETE',
    url: '/roles/' + roleid,
    data: {
        user: userId
    },
    headers: {
        'Content-type': 'application/json;charset=utf-8'
    }
})
.then(function(response) {
    console.log(response.data);
}, function(rejection) {
    console.log(rejection.data);
});

((DefaultTableModel)jTable3.getModel()).setNumRows(0); // delet all table row

Try This:

var img = new Image();

$(img).load(function(){

  $('.container').append($(this));

}).attr({

  src: someRemoteImage

}).error(function(){
  //do something if image cannot load
});

If you give your table a unique id, its easier:

<div id="ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a"
    onmouseup="checkMultipleSelection(this,event);">
       <table id="ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a_table" 
              cellpadding="0" cellspacing="0" border="0" width="100%">
           <tr>
              <td style="width:50px; text-align:left;">09:15 AM</td>
              <td style="width:50px; text-align:left;">Item001</td>
              <td style="width:50px; text-align:left;">10</td>
              <td style="width:50px; text-align:left;">Address1</td>
              <td style="width:50px; text-align:left;">46545465</td>
              <td style="width:50px; text-align:left;">ref1</td>
           </tr>
       </table>
</div>


var multiselect = 
    document.getElementById(
               'ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a_table'
            ).rows[0].cells,
    timeXaddr = [multiselect[0].innerHTML, multiselect[2].innerHTML];

//=> timeXaddr now an array containing ['09:15 AM', 'Address1'];

Answer (Basic is advance!):

Error: 10060 Adding a timeout parameter to request solved the issue for me.

Example 1

import urllib
import urllib2
g = "http://www.google.com/"
read = urllib2.urlopen(g, timeout=20)

Example 2

A similar error also occurred while I was making a GET request. Again, passing a timeout parameter solved the 10060 Error.

response = requests.get(param_url, timeout=20)

This is a bit of an old thread, but since I got here, I figured I'd post my findings so that they might help others.

First, I had the same issue, where I wanted to get the Request.Body and do something with that (logging/auditing). But otherwise I wanted the endpoint to look the same.

So, it seemed like the EnableBuffering() call might do the trick. Then you can do a Seek(0,xxx) on the body and re-read the contents, etc.

However, this led to my next issue. I'd get "Synchornous operations are disallowed" exceptions when accessing the endpoint. So, the workaround there is to set the property AllowSynchronousIO = true, in the options. There are a number of ways to do accomplish this (but not important to detail here..)

THEN, the next issue is that when I go to read the Request.Body it has already been disposed. Ugh. So, what gives?

I am using the Newtonsoft.JSON as my [FromBody] parser in the endpiont call. That is what is responsible for the synchronous reads and it also closes the stream when it's done. Solution? Read the stream before it get's to the JSON parsing? Sure, that works and I ended up with this:

 /// <summary>
/// quick and dirty middleware that enables buffering the request body
/// </summary>
/// <remarks>
/// this allows us to re-read the request body's inputstream so that we can capture the original request as is
/// </remarks>
public class ReadRequestBodyIntoItemsAttribute : AuthorizeAttribute, IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationFilterContext context)
    {
        if (context == null) return;

        // NEW! enable sync IO beacuse the JSON reader apparently doesn't use async and it throws an exception otherwise
        var syncIOFeature = context.HttpContext.Features.Get<IHttpBodyControlFeature>();
        if (syncIOFeature != null)
        {
            syncIOFeature.AllowSynchronousIO = true;

            var req = context.HttpContext.Request;

            req.EnableBuffering();

            // read the body here as a workarond for the JSON parser disposing the stream
            if (req.Body.CanSeek)
            {
                req.Body.Seek(0, SeekOrigin.Begin);

                // if body (stream) can seek, we can read the body to a string for logging purposes
                using (var reader = new StreamReader(
                     req.Body,
                     encoding: Encoding.UTF8,
                     detectEncodingFromByteOrderMarks: false,
                     bufferSize: 8192,
                     leaveOpen: true))
                {
                    var jsonString = reader.ReadToEnd();

                    // store into the HTTP context Items["request_body"]
                    context.HttpContext.Items.Add("request_body", jsonString);
                }

                // go back to beginning so json reader get's the whole thing
                req.Body.Seek(0, SeekOrigin.Begin);
            }
        }
    }
}

So now, I can access the body using the HttpContext.Items["request_body"] in the endpoints that have the [ReadRequestBodyIntoItems] attribute.

But man, this seems like way too many hoops to jump through. So here's where I ended, and I'm really happy with it.

My endpoint started as something like:

[HttpPost("")]
[ReadRequestBodyIntoItems]
[Consumes("application/json")]
public async Task<IActionResult> ReceiveSomeData([FromBody] MyJsonObjectType value)
{
    val bodyString = HttpContext.Items["request_body"];
    // use the body, process the stuff...
}

But it is much more straightforward to just change the signature, like so:

[HttpPost("")]
[Consumes("application/json")]
public async Task<IActionResult> ReceiveSomeData()
{
    using (var reader = new StreamReader(
           Request.Body,
           encoding: Encoding.UTF8,
           detectEncodingFromByteOrderMarks: false
    ))
    {
        var bodyString = await reader.ReadToEndAsync();

        var value = JsonConvert.DeserializeObject<MyJsonObjectType>(bodyString);

        // use the body, process the stuff...
    }
}

I really liked this because it only reads the body stream once, and I have have control of the deserialization. Sure, it's nice if ASP.NET core does this magic for me, but here I don't waste time reading the stream twice (perhaps buffering each time), and the code is quite clear and clean.

If you need this functionality on lots of endpoints, perhaps the middleware approaches might be cleaner, or you can at least encapsulate the body extraction into an extension function to make the code more concise.

Anyways, I did not find any source that touched on all 3 aspects of this issue, hence this post. Hopefully this helps someone!

BTW: This was using ASP .NET Core 3.1.

Okay, I was blind:

e.which

will contain the ASCII code of the key.

See https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/which

according to JAVA documentation, the JDK should be installed in this path:

/Library/Java/JavaVirtualMachines/jdkmajor.minor.macro[_update].jdk

See the uninstall JDK part at https://docs.oracle.com/javase/8/docs/technotes/guides/install/mac_jdk.html

So if you can find such folder then the JDK is installed

If you hit problems where column names are ambiguous, you can do:

date_field = Note.arel_table[:date]
Note.where(user_id: current_user.id, notetype: p[:note_type]).
     where(date_field.gt(p[:date])).
     order(date_field.asc(), Note.arel_table[:created_at].asc())

No.

If the user is sophisticated or determined enough to:

1. Open the Excel VBA editor
2. Use the object browser to see the list of all sheets, including VERYHIDDEN ones
3. Change the property of the sheet to VISIBLE or just HIDDEN

then they are probably sophisticated or determined enough to:

1. Search the internet for "remove Excel 2007 project password"
2. Apply the instructions they find.

So what's on this hidden sheet? Proprietary information like price formulas, or client names, or employee salaries? Putting that info in even an hidden tab probably isn't the greatest idea to begin with.

This cannot be emphasized enough:

Keys only make sense in the context of the surrounding array.

"For example, if you extract a ListItem component, you should keep the key on the <ListItem /> elements in the array rather than on the <li> element in the ListItem itself." -- https://reactjs.org/docs/lists-and-keys.html#extracting-components-with-keys

This worked for me for cardView and will work the same for listview inside adapter calss, within onBindViewHolder() function

holder.cardView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                return false;
            }
        });

Just use crontab -e and follow the tutorial here.

Look at point 3 for a guide on how to specify the frequency.

Based on your requirement, it should effectively be:

*/10 * * * * /usr/bin/python script.py

This is same as the previous solution but I have defined the function in df.apply itself:

df['Value'] = df.apply(lambda row: row['a']%row['c'], axis=1)

For anyone using Ubuntu and receiving this error when loading the page locally, but not on a web hosting service,

I just fixed this by opening up nautilus (sudo nautilus) and right click on the file you're trying to open, click properties > Settings > and give read write to 'everyone else'

Using jQuery throttle / debounce

jQuery debounce is a nice one for problems like this. jsFidlle

$(window).scroll($.debounce( 250, true, function(){
    $('#scrollMsg').html('SCROLLING!');
}));
$(window).scroll($.debounce( 250, function(){
    $('#scrollMsg').html('DONE!');
}));

The second parameter is the "at_begin" flag. Here I've shown how to execute code both at "scroll start" and "scroll finish".

Using Lodash

As suggested by Barry P, jsFiddle, underscore or lodash also have a debounce, each with slightly different apis.

$(window).scroll(_.debounce(function(){
    $('#scrollMsg').html('SCROLLING!');
}, 150, { 'leading': true, 'trailing': false }));

$(window).scroll(_.debounce(function(){
    $('#scrollMsg').html('STOPPED!');
}, 150));

I think these both blog post should help you solving your problem.

http://blog.the-dargans.co.uk/2007/04/programmatically-adding-items-to.html http://asadewa.wordpress.com/2007/11/19/adding-a-custom-content-type-specific-item-on-a-sharepoint-list/

Short walk through:

1. Get a instance of the list you want to add the item to.

2. Add a new item to the list:

   SPListItem newItem = list.AddItem();
   

3. To bind you new item to a content type you have to set the content type id for the new item:

   newItem["ContentTypeId"] = <Id of the content type>;
   

4. Set the fields specified within your content type.

5. Commit your changes:

   newItem.Update();
   

As of Angular Material v9, it now has a clipboard CDK

Just put two inputs inside a div with class form-group and set display flex on the div style

<form method="post">
<div class="form-group" style="display: flex;"><input type="text" class="form-control" name="nome" placeholder="Nome e sobrenome" style="margin-right: 4px;" /><input type="text" class="form-control" style="margin-left: 4px;" name="cpf" placeholder="CPF" /></div>
<div class="form-group" style="display: flex;"><input type="email" class="form-control" name="email" placeholder="Email" style="margin-right: 4px;" /><input type="tel" class="form-control" style="margin-left: 4px;" name="telephone" placeholder="Telefone" /></div>
<div class="form-group"><input type="password" class="form-control" name="password" placeholder="Password" /></div>
<div class="form-group"><input type="password" class="form-control" name="password-repeat" placeholder="Password (repeat)" /></div>
<div class="form-group">
    <div class="form-check"><label class="form-check-label"><input type="checkbox" class="form-check-input" />I agree to the license terms.</label></div>
</div>
<div class="form-group"><button class="btn btn-primary btn-block" type="submit">Sign Up</button></div><a class="already" href="#">You already have an account? Login here.</a></form>

Replace this:

NSDate* now = [NSDate date];
int hour = 23 - [[now dateWithCalendarFormat:nil timeZone:nil] hourOfDay];
int min = 59 - [[now dateWithCalendarFormat:nil timeZone:nil] minuteOfHour];
int sec = 59 - [[now dateWithCalendarFormat:nil timeZone:nil] secondOfMinute];
countdownLabel.text = [NSString stringWithFormat:@"%02d:%02d:%02d", hour, min,sec];

With this:

NSDate* now = [NSDate date];
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *dateComponents = [gregorian components:(NSHourCalendarUnit  | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:now];
NSInteger hour = [dateComponents hour];
NSInteger minute = [dateComponents minute];
NSInteger second = [dateComponents second];
[gregorian release];
countdownLabel.text = [NSString stringWithFormat:@"%02d:%02d:%02d", hour, minute, second];

I installed docker from snap repository. So I also had to start from snap (running Ubuntu).

sudo snap start docker

Otherwise you can also install it from their repositories.

"unblocking" the file fixes the problem. Screenshot:

You can use both Kotlin and Java files in your application.

To switch between the two files, make sure you give them unique < action android:name="" in AndroidManifest.xml, like so:

            <activity android:name=".MainActivityKotlin">
                <intent-filter>
                    <action android:name="com.genechuang.basicfirebaseproject.KotlinActivity"/>
                    <category android:name="android.intent.category.DEFAULT" />
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
            <activity
                android:name="com.genechuang.basicfirebaseproject.MainActivityJava"
                android:label="MainActivityJava" >
                <intent-filter>
                    <action android:name="com.genechuang.basicfirebaseproject.JavaActivity" />
                    <category android:name="android.intent.category.DEFAULT" />
                </intent-filter>
            </activity>

Then in your MainActivity.kt (Kotlin file), to start an Activity written in Java, do this:

       val intent = Intent("com.genechuang.basicfirebaseproject.JavaActivity")
        startActivity(intent)

In your MainActivityJava.java (Java file), to start an Activity written in Kotlin, do this:

       Intent mIntent = new Intent("com.genechuang.basicfirebaseproject.KotlinActivity");
        startActivity(mIntent);

For the links which contains common url have to console in a variable. Then attempt it sequentially.

int linkCount=allLinks.length();
for(int i=0; <linkCount;i++)
{
    driver.findelement(allLinks[i]).click();
}

FIRST, if you want to be able to access man1.py from man1test.py AND manModules.py from man1.py, you need to properly setup your files as packages and modules.

Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module name A.B designates a submodule named B in a package named A.

...

When importing the package, Python searches through the directories on sys.path looking for the package subdirectory.

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path.

You need to set it up to something like this:

man
|- __init__.py
|- Mans
   |- __init__.py
   |- man1.py
|- MansTest
   |- __init.__.py
   |- SoftLib
      |- Soft
         |- __init__.py
         |- SoftWork
            |- __init__.py
            |- manModules.py
      |- Unittests
         |- __init__.py
         |- man1test.py

SECOND, for the "ModuleNotFoundError: No module named 'Soft'" error caused by from ...Mans import man1 in man1test.py, the documented solution to that is to add man1.py to sys.path since Mans is outside the MansTest package. See The Module Search Path from the Python documentation. But if you don't want to modify sys.path directly, you can also modify PYTHONPATH:

sys.path is initialized from these locations:

• The directory containing the input script (or the current directory when no file is specified).
• PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
• The installation-dependent default.

THIRD, for from ...MansTest.SoftLib import Soft which you said "was to facilitate the aforementioned import statement in man1.py", that's now how imports work. If you want to import Soft.SoftLib in man1.py, you have to setup man1.py to find Soft.SoftLib and import it there directly.

With that said, here's how I got it to work.

man1.py:

from Soft.SoftWork.manModules import *
# no change to import statement but need to add Soft to PYTHONPATH

def foo():
    print("called foo in man1.py")
    print("foo call module1 from manModules: " + module1())

man1test.py

# no need for "from ...MansTest.SoftLib import Soft" to facilitate importing..
from ...Mans import man1

man1.foo()

manModules.py

def module1():
    return "module1 in manModules"

Terminal output:

$ python3 -m man.MansTest.Unittests.man1test
Traceback (most recent call last):
  ...
    from ...Mans import man1
  File "/temp/man/Mans/man1.py", line 2, in <module>
    from Soft.SoftWork.manModules import *
ModuleNotFoundError: No module named 'Soft'

$ PYTHONPATH=$PYTHONPATH:/temp/man/MansTest/SoftLib
$ export PYTHONPATH
$ echo $PYTHONPATH
:/temp/man/MansTest/SoftLib
$ python3 -m man.MansTest.Unittests.man1test
called foo in man1.py
foo called module1 from manModules: module1 in manModules 

As a suggestion, maybe re-think the purpose of those SoftLib files. Is it some sort of "bridge" between man1.py and man1test.py? The way your files are setup right now, I don't think it's going to work as you expect it to be. Also, it's a bit confusing for the code-under-test (man1.py) to be importing stuff from under the test folder (MansTest).

OCR can be pretty CPU intensive, you might want to reconsider doing it on a smart phone.

That aside, to my knowledge the popular OCR libraries are Aspire and Tesseract. Neither are straight up Java, so you're not going to get a drop-in Android OCR library.

However, Tesseract is open source (GitHub hosted infact); so you can throw some time at porting the subset you need to Java. My understanding is its not insane C++, so depending on how badly you need OCR it might be worth the time.

So short answer: No.

Long answer: if you're willing to work for it.

This builds on Jon Willis's answer that relies upon assert, which only gets executed in Debug compilations:

func Log(_ str: String) { 
    assert(DebugLog(str)) 
}
func DebugLog(_ str: String) -> Bool { 
    print(str) 
    return true
}

My use case is for logging print statements. Here is a benchmark for Release version on iPhone X:

let iterations = 100_000_000
let time1 = CFAbsoluteTimeGetCurrent()
for i in 0 ..< iterations {
    Log ("? unarchiveArray:\(fileName) memoryTime:\(memoryTime) count:\(array.count)")
}
var time2 = CFAbsoluteTimeGetCurrent()
print ("Log: \(time2-time1)" )

prints:

Log: 0.0

Looks like Swift 4 completely eliminates the function call.

You might not be able to change npm registry using .bat file as Gntem pointed out. But I understand that you need the ability to automate changing registries. You can do so by having your .npmrc configs in separate files (say npmrc_jfrog & npmrc_default) and have your .bat files do the copying task.

For example (in Windows): Your default_registry.bat will have

xcopy /y npmrc_default .npmrc

and your jfrog_registry.bat will have

xcopy /y npmrc_jfrog .npmrc

Note: /y suppresses prompting to confirm that you want to overwrite an existing destination file.

This will make sure that all the config properties (registry, proxy, apiKeys, etc.) get copied over to .npmrc.

You can read more about xcopy here.

As said, numpy.empty() is the way to go. However, for objects, fill() might not do exactly what you think it does:

In[36]: a = numpy.empty(5,dtype=object)
In[37]: a.fill([])
In[38]: a
Out[38]: array([[], [], [], [], []], dtype=object)
In[39]: a[0].append(4)
In[40]: a
Out[40]: array([[4], [4], [4], [4], [4]], dtype=object)

One way around can be e.g.:

In[41]: a = numpy.empty(5,dtype=object)
In[42]: a[:]= [ [] for x in range(5)]
In[43]: a[0].append(4)
In[44]: a
Out[44]: array([[4], [], [], [], []], dtype=object)

You shouldn't use CascadeType.ALL on @ManyToOne since entity state transitions should propagate from parent entities to child ones, not the other way around.

The @ManyToOne side is always the Child association since it maps the underlying Foreign Key column.

Therefore, you should move the CascadeType.ALL from the @ManyToOne association to the @OneToMany side, which should also use the mappedBy attribute since it's the most efficient one-to-many table relationship mapping.

Adding to jelovirt's answer, you can use number() to convert the value to a number, then round(), floor(), or ceiling() to get a whole integer.

Example

<xsl:variable name="MyValAsText" select="'5.14'"/>
<xsl:value-of select="number($MyValAsText) * 2"/> <!-- This outputs 10.28 -->
<xsl:value-of select="floor($MyValAsText)"/> <!-- outputs 5 -->
<xsl:value-of select="ceiling($MyValAsText)"/> <!-- outputs 6 -->
<xsl:value-of select="round($MyValAsText)"/> <!-- outputs 5 -->

If checkout master was the last thing you did, then the reflog entry HEAD@{1} will contain your commits (otherwise use git reflog or git log -p to find them). Use git merge HEAD@{1} to fast forward them into master.

EDIT:

As noted in the comments, Git Ready has a great article on this.

git reflog and git reflog --all will give you the commit hashes of the mis-placed commits.

I strongly recommend: iTextSharp

There is U+1F50D LEFT-POINTING MAGNIFYING GLASS () and U+1F50E RIGHT-POINTING MAGNIFYING GLASS ().

You should use (in HTML) 🔍 or 🔎

They are, however not supported by many fonts (fileformat.info only lists a few fonts as supporting the Codepoint with a proper glyph).

Also note that they are outside of the BMP, so some Unicode-capable software might have problems rendering them, even if they have fonts that support them.

Generally Unicode Glyphs can be searched using a site such as fileformat.info. This searches "only" in the names and properties of the Unicode glyphs, but they usually contain enough metadata to allow for good search results (for this answer I searched for "glass" and browsed the resulting list, for example)

The api is fairly easy to use.

// Lookup the dns, if the ip exists.
 if (!ip.isEmpty()) {
     InetAddress inetAddress = InetAddress.getByName(ip);
     dns = inetAddress.getCanonicalHostName(); 
 }

Beautiful Soup 4 allows you to set a formatter to your output

If you pass in formatter=None, Beautiful Soup will not modify strings at all on output. This is the fastest option, but it may lead to Beautiful Soup generating invalid HTML/XML, as in these examples:

print(soup.prettify(formatter=None))
# <html>
#  <body>
#   <p>
#    Il a dit <<Sacré bleu!>>
#   </p>
#  </body>
# </html>

link_soup = BeautifulSoup('<a href="http://example.com/?foo=val1&bar=val2">A link</a>')
print(link_soup.a.encode(formatter=None))
# <a href="http://example.com/?foo=val1&bar=val2">A link</a>

For those stumbling upon this from MySQL or Oracle background - MySQL supports the LIMIT clause to select a limited number of records, while Oracle uses ROWNUM.

Set the connection string in your config file:

<connectionStrings>
    <add name="ConnString"
         connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\gadgetDatabase.mdf;Integrated Security=True" />
</connectionStrings>

You can also run ->select('DISTINCT `field`', FALSE) and the second parameter tells CI not to escape the first argument.

With the second parameter as false, the output would be SELECT DISTINCT `field` instead of without the second parameter, SELECT `DISTINCT` `field`

You could also use Hex Color Code,

Name    Hex Color Code  RGB Color Code
Red     #FF0000         rgb(255, 0, 0)
Maroon  #800000         rgb(128, 0, 0)
Yellow  #FFFF00         rgb(255, 255, 0)
Olive   #808000         rgb(128, 128, 0)

For example

import matplotlib.pyplot as plt
import random

number_of_colors = 8

color = ["#"+''.join([random.choice('0123456789ABCDEF') for j in range(6)])
             for i in range(number_of_colors)]
print(color)

['#C7980A', '#F4651F', '#82D8A7', '#CC3A05', '#575E76', '#156943', '#0BD055', '#ACD338']

Lets try plotting them in a scatter plot

for i in range(number_of_colors):
    plt.scatter(random.randint(0, 10), random.randint(0,10), c=color[i], s=200)

plt.show()

I think is not possible to do that. It would be a huge security risk if a browser access to that kind of personal information

you can test a color by writing the CSS inline like <div style="color:red";>...</div>

I was having a similar issue like yours, except that I wanted a specific subset of 'ancestry'. Hong Ning's query was a good start, except it will return combined records containing duplicates and/or extra ancestries (e.g. it would also return someone with ancestries ('England', 'France', 'Germany', 'Netherlands') and ('England', 'France', 'England'). Supposing you'd want just the three and only the three, you'd need the following query:

SELECT Src.user_id
FROM yourtable Src
WHERE ancestry in ('England', 'France', 'Germany')
    AND EXISTS (
        SELECT user_id
        FROM dbo.yourtable
        WHERE user_id = Src.user_id
        GROUP BY user_id
        HAVING COUNT(DISTINCT ancestry) = 3
        )
GROUP BY user_id
HAVING COUNT(DISTINCT ancestry) = 3

The same issue i was facing couple of months back and that is because end of free google map usage effective from i think June 11, 2018. Google does not provide free google maps now. You need to have a valid API key and valid billing used, which may give you 200$ of free usage.

Refer link for more details: Google map pricing

Follow the process here to get your api key.

If you are upto using only maps with specific user, you can try other map tools.

x="Alpha_beta_Gamma"
is_uppercase_letter = True in map(lambda l: l.isupper(), x)
print is_uppercase_letter
>>>>True

So you can write it in 1 string

I am just sharing my experience here, I used angular.copy() for comparing two objects properties. I was working on a number of inputs without form element, I was wondering how to compare two objects properties and based on result I have to enable and disable the save button. So I used as below.

I assigned an original server object user values to my dummy object to say userCopy and used watch to check changes to the user object.

My server API which gets me data from the server:

var req = {
    method: 'GET',
    url: 'user/profile/' + id,
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}
$http(req).success(function(data) {
    $scope.user = data;
    $scope.userCopy = angular.copy($scope.user);
    $scope.btnSts=true;
}).error(function(data) {
    $ionicLoading.hide();
});

//initially my save button is disabled because objects are same, once something 
//changes I am activating save button

$scope.btnSts = true;
$scope.$watch('user', function(newVal, oldVal) {
    console.log($scope.userCopy.name);

    if ($scope.userCopy.name !== $scope.user.name || $scope.userCopy.email !== $scope.user.email) {
        console.log('Changed');
        $scope.btnSts = false;
    } else {
        console.log('Unchanged');
        $scope.btnSts = true;
    }    
}, true);

I am not sure but comparing two objects was really headache for me always but with angular.copy() it went smoothly.

I didnt try Sumama Waheed's answer but what worked for me was replacing the bin/catalina.jar with a working jar (I disposed of an older tomcat) and after adding in NetBeans, I put the original catalina.jar again.

As others have mentioned, you are probably not implementing equals() correctly.

However, you should also note that this code is considered quite inefficient, since the runtime could be the number of elements squared.

You might want to consider using a Set structure instead of a List instead, or building a Set first and then turning it into a list.

try to put below html in head tag.It worked for me.

 <title>ABC</title>
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> 
 <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">

OK, now I feel stupid. The first two definitely do not work but the second two do. Not sure how I convinced my self that I had tried them. Sorry for wasting everyone's time.

In case this helps anyone else, this can occur when you are trying to make a new file in a directory that does not exist.

If you are using the grid or alike component: In XAML, make sure that the elements in the grid have Grid.Row and Grid.Column defined, and ensure tha they don't have margins. If you used designer mode, or Expression Blend, it could have assigned margins relative to the whole grid instead of to particular cells. As for cell sizing, I add an extra cell that fills up the rest of the space:

    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>

Don't know what you are doing (helpful to show what you tried that didn't work), but your claim that cex.axis only affects the x-axis is not true:

set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data = foo, cex.axis = 3)

at least for me with:

Also, cex.axis affects the labelling of tick marks. cex.lab is used to control what R call the axis labels.

plot(Y ~ X, data = foo, cex.lab = 3)

but even that works for both the x- and y-axis.

Following up Jens' comment about using barplot(). Check out the cex.names argument to barplot(), which allows you to control the bar labels:

dat <- rpois(10, 3) names(dat) <- LETTERS[1:10] barplot(dat, cex.names = 3, cex.axis = 2)

As you mention that cex.axis was only affecting the x-axis I presume you had horiz = TRUE in your barplot() call as well? As the bar labels are not drawn with an axis() call, applying Joris' (otherwise very useful) answer with individual axis() calls won't help in this situation with you using barplot()

This is due to a bug in Webkit.

You can work around the Webkit bug using createEvent('Event') rather than createEvent('KeyboardEvent'), and then assigning the keyCode property. See this answer and this example.

I check length.

if (str.length == 0) {
}

look at this

using CsvFramework;

using System.Collections.Generic;

namespace CvsParser {

public class Customer
{
    public int Id { get; set; }
    public string Name { get; set; }
    public List<Order> Orders { get; set; }        
}

public class Order
{
    public int Id { get; set; }

    public int CustomerId { get; set; }
    public int Quantity { get; set; }

    public int Amount { get; set; }

    public List<OrderItem> OrderItems { get; set; }

}

public class Address
{
    public int Id { get; set; }
    public int CustomerId { get; set; }

    public string Name { get; set; }
}

public class OrderItem
{
    public int Id { get; set; }
    public int OrderId { get; set; }

    public string ProductName { get; set; }
}

class Program
{
    static void Main(string[] args)
    {

        var customerLines = System.IO.File.ReadAllLines(@"Customers.csv");
        var orderLines = System.IO.File.ReadAllLines(@"Orders.csv");
        var orderItemLines = System.IO.File.ReadAllLines(@"OrderItemLines.csv");

        CsvFactory.Register<Customer>(builder =>

            builder.Add(a => a.Id).Type(typeof(int)).Index(0).IsKey(true);
            builder.Add(a => a.Name).Type(typeof(string)).Index(1);
            builder.AddNavigation(n => n.Orders).RelationKey<Order, int>(k => k.CustomerId);

        }, false, ',', customerLines);

        CsvFactory.Register<Order>(builder =>
        {
            builder.Add(a => a.Id).Type(typeof(int)).Index(0).IsKey(true);

        }, false, ',', orderItemLines);



        var customers = CsvFactory.Parse<Customer>();


    }
}

}

@blytung Has a nice function to replace that function

<?php
$url = "http://www.example.org/";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$contents = curl_exec($ch);
if (curl_errno($ch)) {
  echo curl_error($ch);
  echo "\n<br />";
  $contents = '';
} else {
  curl_close($ch);
}

if (!is_string($contents) || !strlen($contents)) {
echo "Failed to get contents.";
$contents = '';
}

echo $contents;
?>    

You can check it by compiling,and running this small C++ program.

#include <iostream>
#include <conio.h>
#include <cstdlib>

int show;
int main()
{    
while(true)
    {
    int show = getch();
    std::cout << show;
    }
getch(); // Just to keep the console open after program execution  
}

Let me expand a bit on a VonC's very comprehensive answer:

First, if I remember it correctly, the fact that Git by default doesn't create merge commits in the fast-forward case has come from considering single-branch "equal repositories", where mutual pull is used to sync those two repositories (a workflow you can find as first example in most user's documentation, including "The Git User's Manual" and "Version Control by Example"). In this case you don't use pull to merge fully realized branch, you use it to keep up with other work. You don't want to have ephemeral and unimportant fact when you happen to do a sync saved and stored in repository, saved for the future.

Note that usefulness of feature branches and of having multiple branches in single repository came only later, with more widespread usage of VCS with good merging support, and with trying various merge-based workflows. That is why for example Mercurial originally supported only one branch per repository (plus anonymous tips for tracking remote branches), as seen in older revisions of "Mercurial: The Definitive Guide".

Second, when following best practices of using feature branches, namely that feature branches should all start from stable version (usually from last release), to be able to cherry-pick and select which features to include by selecting which feature branches to merge, you are usually not in fast-forward situation... which makes this issue moot. You need to worry about creating a true merge and not fast-forward when merging a very first branch (assuming that you don't put single-commit changes directly on 'master'); all other later merges are of course in non fast-forward situation.

As aditional information on @Quentin answer, and as he rightly says, background CSS property itself, is a shorthand for:

background-color
background-image
background-repeat
background-attachment
background-position

That's mean, you can group all styles in one, like:

background: red url(../img.jpg) 0 0 no-repeat fixed;

This would be (in this example):

background-color: red;
background-image: url(../img.jpg);
background-repeat: no-repeat;
background-attachment: fixed;
background-position: 0 0;

So... when you set: background:none;
you are saying that all the background properties are set to none...
You are saying that background-image: none; and all the others to the initial state (as they are not being declared).
So, background:none; is:

background-color: initial;
background-image: none;
background-repeat: initial;
background-attachment: initial;
background-position: initial;

Now, when you define only the color (in your case transparent) then you are basically saying:

background-color: transparent;
background-image: initial;
background-repeat: initial;
background-attachment: initial;
background-position: initial;

I repeat, as @Quentin rightly says the default transparent and none values in this case are the same, so in your example and for your original question, No, there's no difference between them.

But!.. if you say background:none Vs background:red then yes... there's a big diference, as I say, the first would set all properties to none/default and the second one, will only change the color and remains the rest in his default state.

So in brief:

Short answer: No, there's no difference at all (in your example and orginal question)
Long answer: Yes, there's a big difference, but depends directly on the properties granted to attribute.

Upd1: Initial value (aka default)

Initial value the concatenation of the initial values of its longhand properties:

background-image: none
background-position: 0% 0%
background-size: auto auto
background-repeat: repeat
background-origin: padding-box
background-style: is itself a shorthand, its initial value is the concatenation of its own longhand properties
background-clip: border-box
background-color: transparent

See more background descriptions here

Upd2: Clarify better the background:none; specification.

Just for the sake of completeness, I would suggest using the InnerHTML way as well - even though I would not call it the best way...

document.getElementById("image-holder").innerHTML = "<img src='image.png' alt='The Image' />";

By the way, innerHTML is not that bad

You can use it to raise errors as part of error-checking:

if (a < b):
    raise ValueError()

Or handle some errors, and then pass them on as part of error-handling:

try:
    f = open('file.txt', 'r')
except IOError:
    # do some processing here
    # and then pass the error on
    raise

Type g++(or make) on terminal.

This will prompt for you to install the developer tools, if they are missing.

Also the size will be very less when compared to xcode

I did it in this simple way, with Web API 2.0. You can remove UseDefaultCredentials. I used it for my own use cases.

List<YourObject> listObjects = new List<YourObject>();

string response = "";
using (var client = new WebClient() { UseDefaultCredentials = true })
{
     response = client.DownloadString(apiUrl);
}

listObjects = JsonConvert.DeserializeObject<List<YourObject>>(response);
return listObjects;

  
import re

ab = re.compile("^([A-Z]{1}[0-9]{1})+$")
ab.match(string)
  

I believe that should work for an uppercase, number pattern.

From an efficiency perspective, you're not going to beat

s.translate(None, string.punctuation)

For higher versions of Python use the following code:

s.translate(str.maketrans('', '', string.punctuation))

It's performing raw string operations in C with a lookup table - there's not much that will beat that but writing your own C code.

If speed isn't a worry, another option though is:

exclude = set(string.punctuation)
s = ''.join(ch for ch in s if ch not in exclude)

This is faster than s.replace with each char, but won't perform as well as non-pure python approaches such as regexes or string.translate, as you can see from the below timings. For this type of problem, doing it at as low a level as possible pays off.

Timing code:

import re, string, timeit

s = "string. With. Punctuation"
exclude = set(string.punctuation)
table = string.maketrans("","")
regex = re.compile('[%s]' % re.escape(string.punctuation))

def test_set(s):
    return ''.join(ch for ch in s if ch not in exclude)

def test_re(s):  # From Vinko's solution, with fix.
    return regex.sub('', s)

def test_trans(s):
    return s.translate(table, string.punctuation)

def test_repl(s):  # From S.Lott's solution
    for c in string.punctuation:
        s=s.replace(c,"")
    return s

print "sets      :",timeit.Timer('f(s)', 'from __main__ import s,test_set as f').timeit(1000000)
print "regex     :",timeit.Timer('f(s)', 'from __main__ import s,test_re as f').timeit(1000000)
print "translate :",timeit.Timer('f(s)', 'from __main__ import s,test_trans as f').timeit(1000000)
print "replace   :",timeit.Timer('f(s)', 'from __main__ import s,test_repl as f').timeit(1000000)

This gives the following results:

sets      : 19.8566138744
regex     : 6.86155414581
translate : 2.12455511093
replace   : 28.4436721802

If still help, verify the name of archive, it must be exact "log4j.properties" or "log4j.xml" (case sensitive), and follow the hint by "Alain O'Dea". I was geting the same error, but after make these changes everthing works fine. just like a charm :-). hope this helps.

The pip wheel contains the python version in its name (cp34-cp34m). If you download the whl file and rename it to say py3-none or instead, it should work. Can you try that?

The installation won't work for anaconda users that choose python 3 support because the installation procedure is asking to create a python 3.5 environment and the file is currently called cp34-cp34m. So renaming it would do the job for now.

sudo pip3 install --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.7.0-cp34-cp34m-linux_x86_64.whl

This will produced the exact error message you got above. However, when you will downloaded the file yourself and rename it to "tensorflow-0.7.0-py3-none-linux_x86_64.whl", then execute the command again with changed filename, it should work fine.

Java has Reflection (java.reflection.*), but I would suggest looking into a library like Apache Beanutils, it will make the process much less hairy than using reflection directly.

Try this:

update table YourTable
set YourField = substring(YourField, 5, len(YourField)-3);

Add extra columns as null for the table having less columns like

Select Col1, Col2, Col3, Col4, Col5 from Table1
Union
Select Col1, Col2, Col3, Null as Col4, Null as Col5 from Table2

With the commit introduced today (Nov 25), you can now specify a port number right after the run or start sbt commands.

For instance

play run 8080 or play start 8080

Play defaults to port 9000

 #alertlist li:hover:after,#alertlist li.selected:after
{
    position:absolute;
    top: 0;
    right:-10px;
    bottom:0;

    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;
    border-left: 10px solid #303030;
    content: "";
}?

Another Note: z-index must be considered when looking at children objects relative to other objects.

For example

<div class="container">
    <div class="branch_1">
        <div class="branch_1__child"></div>
    </div>
    <div class="branch_2">
        <div class="branch_2__child"></div>
    </div>
</div>

If you gave branch_1__child a z-index of 99 and you gave branch_2__child a z-index of 1, but you also gave your branch_2 a z-index of 10 and your branch_1 a z-index of 1, your branch_1__child still will not show up in front of your branch_2__child

Anyways, what I'm trying to say is; if a parent of an element you'd like to be placed in front has a lower z-index than its relative, that element will not be placed higher.

The z-index is relative to its containers. A z-index placed on a container farther up in the hierarchy basically starts a new "layer"

Incep[inception]tion

Here's a fiddle to play around:

https://jsfiddle.net/orkLx6o8/

After hours of struggling with this problem, I stumbled upon a solution that worked for me:

In SSDT (2012), I had originally had my Page Setup/Page units set to Centimeters. When I changed this to Inches, strangely enough, I was able to export my report to PDF without having every other page be blank.

instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0; once your window has scrolled pass a certain height:

jQuery

  $(window).scroll(function(){
      if ($(this).scrollTop() > 135) {
          $('#task_flyout').addClass('fixed');
      } else {
          $('#task_flyout').removeClass('fixed');
      }
  });

css

.fixed {position:fixed; top:0; left:0;}

Example

Tensorflow is now supported on Python 3.6. Just make sure that the Python installation is 64 bit on a 64 bit machine and that pip is the latest (pip install --upgrade pip).

After that (pip install --upgrade tensorflow) works like a charm.

Taking reference of ThiefMaster? sometimes we get an error with value given as '\n' or null and perform for that required to handle ValueError:

Handling the exception is the way to go

try:
    gotdata = dlist[1]
except (IndexError, ValueError):
    gotdata = 'null'

plt.figure(figsize=(15,10))
graph = sns.barplot(x='name_column_x_axis', y="name_column_x_axis", data = dataframe_name ,  color="salmon")
for p in graph.patches:
        graph.annotate('{:.0f}'.format(p.get_height()), (p.get_x()+0.3, p.get_height()),
                    ha='center', va='bottom',
                    color= 'black')

I got this error after change a loop in my program, let`s see:

for ...
  for ... 
     x_batch.append(one_hot(int_word, vocab_size))
     y_batch.append(one_hot(int_nb, vocab_size, value))
  ...
  ...
  if ...
        x_batch = np.asarray(x_batch)
        y_batch = np.asarray(y_batch)
...

In fact, I was reusing the variable and forgot to reset them inside the external loop, like the comment of John Lyon:

for ...
  x_batch = []
  y_batch = []
  for ... 
     x_batch.append(one_hot(int_word, vocab_size))
     y_batch.append(one_hot(int_nb, vocab_size, value))
  ...
  ...
  if ...
        x_batch = np.asarray(x_batch)
        y_batch = np.asarray(y_batch)
...

Then, check if you are using np.asarray() or something like that.

For MYSQL

ALTER TABLE myTable MODIFY myColumn {DataType} NULL

for rational numbers use this one: (([0-9]+.[0-9]*)|([0-9]*.[0-9]+)|([0-9]+))

Id advice you to use a bit simplier method -

$.post('edit.php', {title: $('input[name="title"]').val() }, function(resp){
    alert(resp);
});

try this one, I just feels its syntax is simplier than the $.ajax's one...

I use ciso8601, which is 62x faster than datetime's strptime.

t = "01/12/2011"
ts = ciso8601.parse_datetime(t)
# to get time in seconds:
time.mktime(ts.timetuple())

You can learn more here.

Here is what i have done to find the version: just write SELECT @@version and it will give you the version.

I got the following:

jQuery('#tableId').find('tr').index();

I want to return odd numbers of an array

If i read that correctly, you want something like this?

List<Integer> getOddNumbers(int[] integers) {
  List<Integer> oddNumbers = new ArrayList<Integer>();
  for (int i : integers)
    if (i % 2 != 0)
      oddNumbers.add(i);
  return oddNumbers;
}

This is nice:

myArrayOfMatrices = zeros(unknown,500,800);

If you're running out of memory throw more RAM in your system, and make sure you're running a 64 bit OS. Also try reducing your precision (do you really need doubles or can you get by with singles?):

myArrayOfMatrices = zeros(unknown,500,800,'single');

To append to that array try:

myArrayOfMatrices(unknown+1,:,:) = zeros(500,800);

Perhaps the best way to explain it is with an example:

1. Alice creates topic branch A, and works on it
2. Bob creates unrelated topic branch B, and works on it
3. Alice does git checkout master && git pull. Master is already up to date.
4. Bob does git checkout master && git pull. Master is already up to date.
5. Alice does git merge topic-branch-A
6. Bob does git merge topic-branch-B
7. Bob does git push origin master before Alice
8. Alice does git push origin master, which is rejected because it's not a fast-forward merge.
9. Alice looks at origin/master's log, and sees that the commit is unrelated to hers.
10. Alice does git pull --rebase origin master
11. Alice's merge commit is unwound, Bob's commit is pulled, and Alice's commit is applied after Bob's commit.
12. Alice does git push origin master, and everyone is happy they don't have to read a useless merge commit when they look at the logs in the future.

Note that the specific branch being merged into is irrelevant to the example. Master in this example could just as easily be a release branch or dev branch. The key point is that Alice & Bob are simultaneously merging their local branches to a shared remote branch.

You could use the random.sample function from the standard library to select k elements from a population:

import random
random.sample(range(low, high), n)

In case of a rather large range of possible numbers, you could use itertools.islice with an infinite random generator:

import itertools
import random

def random_gen(low, high):
    while True:
        yield random.randrange(low, high)

gen = random_gen(1, 100)
items = list(itertools.islice(gen, 10))  # Take first 10 random elements

After the question update it is now clear that you need n distinct (unique) numbers.

import itertools
import random

def random_gen(low, high):
    while True:
        yield random.randrange(low, high)

gen = random_gen(1, 100)

items = set()

# Try to add elem to set until set length is less than 10
for x in itertools.takewhile(lambda x: len(items) < 10, gen):
    items.add(x)

du -sk * | sort -n will sort the folders by size. Helpful when looking to clear space..

$('#3').remove();

What you could do is have the selected attribute on the <select> tag be an attribute of this.state that you set in the constructor. That way, the initial value you set (the default) and when the dropdown changes you need to change your state.

constructor(){
  this.state = {
    selectedId: selectedOptionId
  }
}

dropdownChanged(e){
  this.setState({selectedId: e.target.value});
}

render(){
  return(
    <select value={this.selectedId} onChange={this.dropdownChanged.bind(this)}>
      {option_id.map(id =>
        <option key={id} value={id}>{options[id].name}</option>
      )}
    </select>
  );
}

To accomplish what you're describing will take two steps...

• The file needs to be added to the source tarball
• setup.py needs to be modified to install the data file to the source path

Step 1: To add the file to the source tarball, include it in the MANIFEST

Create a MANIFEST template in the folder that contains setup.py

The MANIFEST is basically a text file with a list of all the files that will be included in the source tarball.

Here's what the MANIFEST for my project look like:

• CHANGELOG.txt
• INSTALL.txt
• LICENSE.txt
• pypreprocessor.py
• README.txt
• setup.py
• test.py
• TODO.txt

Note: While sdist does add some files automatically, I prefer to explicitly specify them to be sure instead of predicting what it does and doesn't.

Step 2: To install the data file to the source folder, modify setup.py

Since you're looking to add a data file (LICENSE.txt) to the source install folder you need to modify the data install path to match the source install path. This is necessary because, by default, data files are installed to a different location than source files.

To modify the data install dir to match the source install dir...

Pull the install dir info from distutils with:

from distutils.command.install import INSTALL_SCHEMES

Modify the data install dir to match the source install dir:

for scheme in INSTALL_SCHEMES.values():
    scheme['data'] = scheme['purelib']

And, add the data file and location to setup():

data_files=[('', ['LICENSE.txt'])]

Note: The steps above should accomplish exactly what you described in a standard manner without requiring any extension libraries.

There are several different ways you can handle this. You could add a RequiredFieldValidator as well as a RangeValidator (if that works for your case) or you could add a CustomFieldValidator.

Link to the CustomFieldValidator: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.customvalidator%28VS.71%29.aspx

Link to MSDN Article on ASP.NET Validation: http://msdn.microsoft.com/en-us/library/aa479045.aspx

I see two problems:

DOUBLE(10) precision definitions need a total number of digits, as well as a total number of digits after the decimal:

DOUBLE(10,8) would make be ten total digits, with 8 allowed after the decimal.

Also, you'll need to specify your id column as a key :

CREATE TABLE transactions( 
id int NOT NULL AUTO_INCREMENT, 
location varchar(50) NOT NULL, 
description varchar(50) NOT NULL, 
category varchar(50) NOT NULL, 
amount double(10,9) NOT NULL, 
type varchar(6) NOT NULL,  
notes varchar(512), 
receipt int(10), 
PRIMARY KEY(id) );

If you have a Tensor t, calling t.eval() is equivalent to calling tf.get_default_session().run(t).

You can make a session the default as follows:

t = tf.constant(42.0)
sess = tf.Session()
with sess.as_default():   # or `with sess:` to close on exit
    assert sess is tf.get_default_session()
    assert t.eval() == sess.run(t)

The most important difference is that you can use sess.run() to fetch the values of many tensors in the same step:

t = tf.constant(42.0)
u = tf.constant(37.0)
tu = tf.mul(t, u)
ut = tf.mul(u, t)
with sess.as_default():
   tu.eval()  # runs one step
   ut.eval()  # runs one step
   sess.run([tu, ut])  # evaluates both tensors in a single step

Note that each call to eval and run will execute the whole graph from scratch. To cache the result of a computation, assign it to a tf.Variable.

Recently I ran into update_attribute vs. update_attributes and validation issue, so similar names, so different behavior, so confusing.

In order to pass hash to update_attribute and bypass validation you can do:

object = Object.new
object.attributes = {
  field1: 'value',
  field2: 'value2',
  field3: 'value3'
}
object.save!(validate: false)

First of all, you can't pass to alert second argument, use concatenation instead

alert("Input is " + inputValue);

Example

However in order to get values from input better to use states like this

var MyComponent = React.createClass({_x000D_
  getInitialState: function () {_x000D_
    return { input: '' };_x000D_
  },_x000D_
_x000D_
  handleChange: function(e) {_x000D_
    this.setState({ input: e.target.value });_x000D_
  },_x000D_
_x000D_
  handleClick: function() {_x000D_
    console.log(this.state.input);_x000D_
  },_x000D_
_x000D_
  render: function() {_x000D_
    return (_x000D_
      <div>_x000D_
        <input type="text" onChange={ this.handleChange } />_x000D_
        <input_x000D_
          type="button"_x000D_
          value="Alert the text input"_x000D_
          onClick={this.handleClick}_x000D_
        />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
});_x000D_
_x000D_
ReactDOM.render(_x000D_
  <MyComponent />,_x000D_
  document.getElementById('container')_x000D_
);

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_

<div id="container"></div>

For those who do not have 4.5, Here is my library function that reads json. It requires a project reference to System.Web.Extensions.

using System.Web.Script.Serialization;

public object DeserializeJson<T>(string Json)
{
    JavaScriptSerializer JavaScriptSerializer = new JavaScriptSerializer();
    return JavaScriptSerializer.Deserialize<T>(Json);
}

Usually, json is written out based on a contract. That contract can and usually will be codified in a class (T). Sometimes you can take a word from the json and search the object browser to find that type.

Example usage:

Given the json

{"logEntries":[],"value":"My Code","text":"My Text","enabled":true,"checkedIndices":[],"checkedItemsTextOverflows":false}

You could parse it into a RadComboBoxClientState object like this:

string ClientStateJson = Page.Request.Form("ReportGrid1_cboReportType_ClientState");
RadComboBoxClientState RadComboBoxClientState = DeserializeJson<RadComboBoxClientState>(ClientStateJson);
return RadComboBoxClientState.Value;

Other solutions are good enough to answer your query. However, if you are looking for just one command to do that for you -

Create a file name "run", in directory where your Java files are. And save this in your file -

javac "$1.java"
if [ $? -eq 0 ]; then
  echo "--------Run output-------"
  java "$1"
fi

give this file run permission by running -

chmod 777 

Now you can run any of your files by merely running -

./run <yourfilename> (don't add .java in filename)

If you're getting this error through a service account like Visual Studio TFS Build controller service or any other background service, make sure you restart the service after installing npm as the new PATH environment settings will not be picked up by those already running processes. I was getting same error through my build service but I had npm installed and running in the console.

Here are a few simple examples to see the difference in action:

See the list of numbers here:

nums = [1, 9, -3, 4, 8, 5, 7, 14]

When calling sorted on this list, sorted will make a copy of the list. (Meaning your original list will remain unchanged.)

Let's see.

sorted(nums)

returns

[-3, 1, 4, 5, 7, 8, 9, 14]

Looking at the nums again

nums

We see the original list (unaltered and NOT sorted.). sorted did not change the original list

[1, 2, -3, 4, 8, 5, 7, 14]

Taking the same nums list and applying the sort function on it, will change the actual list.

Let's see.

Starting with our nums list to make sure, the content is still the same.

nums

[-3, 1, 4, 5, 7, 8, 9, 14]

nums.sort()

Now the original nums list is changed and looking at nums we see our original list has changed and is now sorted.

nums
[-3, 1, 2, 4, 5, 7, 8, 14]

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

select InitialPayment * MonthlyRate as MultiplyingCalculation, InitialPayment - MonthlyRate as SubtractingCalculation from Payment

I think it will work

for (int i = 1; i <= broj_ds; i++ ) 
  { 

     QuantityInIssueUnit_value = dr_art_line_2[i]["Column"];
     QuantityInIssueUnit_uom  = dr_art_line_2[i]["Column"];

  }

When you visited https://localhost previously at some point it not only visited this over a secure channel (https rather than http), it also told your browser, using a special HTTP header: Strict-Transport-Security (often abbreviated to HSTS), that it should ONLY use https for all future visits.

This is a security feature web servers can use to prevent people being downgraded to http (either intentionally or by some evil party).

However if you then then turn off your https server, and just want to browse http you can't (by design - that's the point of this security feature).

HSTS also does prevents you from accepting and skipping past certificate errors.

To reset this, so HSTS is no longer set for localhost, type the following in your Chrome address bar:

chrome://net-internals/#hsts

Where you will be able to delete this setting for "localhost".

You might also want to find out what was setting this to avoid this problem in future!

Note that for other sites (e.g. www.google.com) these are "preloaded" into the Chrome code and so cannot be removed. When you query them at chrome://net-internals/#hsts you will see them listed as static HSTS entries.

And finally note that Google has started preloading HSTS for the entire .dev domain: https://ma.ttias.be/chrome-force-dev-domains-https-via-preloaded-hsts/

Simple fix that works in old browsers (but does use tables, and requires a height to be set):

<div style="width:100%;height:40px;position:absolute;top:50%;margin-top:-20px;">
  <table style="width:100%"><tr><td align="center">
    In the middle
  </td></tr></table>
</div>

This will spool the output from the anonymous block into a file called output_<YYYYMMDD>.txt located in the root of the local PC C: drive where <YYYYMMDD> is the current date:

SET SERVEROUTPUT ON FORMAT WRAPPED
SET VERIFY OFF

SET FEEDBACK OFF
SET TERMOUT OFF

EDIT:

After your comment to output a value for every iteration of a cursor (I realise each value will be the same in this example but you should get the gist of what i'm doing):

BEGIN

   --
   FOR i IN 1 .. 10
   LOOP
      c := a+10;
      -- Output the value of C

END; 

A segfault is accessing memory that you're not allowed to access. It's read-only, you don't have permission, etc...

A bus error is trying to access memory that can't possibly be there. You've used an address that's meaningless to the system, or the wrong kind of address for that operation.

This is (of course) totally VM-dependent.

Browsing through the source code of OpenJDK 7 and 8 java.util.ArrayList, .Hashtable, .AbstractCollection, .PriorityQueue, and .Vector, you can see this claim being repeated:

/**
 * Some VMs reserve some header words in an array.
 * Attempts to allocate larger arrays may result in
 * OutOfMemoryError: Requested array size exceeds VM limit
 */
private static final int MAX_ARRAY_SIZE = Integer.MAX_VALUE - 8;

which is added by Martin Buchholz (Google) on 2010-05-09; reviewed by Chris Hegarty (Oracle).

So, probably we can say that the maximum "safe" number would be 2 147 483 639 (Integer.MAX_VALUE - 8) and "attempts to allocate larger arrays may result in OutOfMemoryError".

(Yes, Buchholz's standalone claim does not include backing evidence, so this is a calculated appeal to authority. Even within OpenJDK itself, we can see code like return (minCapacity > MAX_ARRAY_SIZE) ? Integer.MAX_VALUE : MAX_ARRAY_SIZE; which shows that MAX_ARRAY_SIZE does not yet have a real use.)

The simplest solution I found for simply limiting the string length was {{ modal.title | slice:0:20 }}, and then borrowing from @Govan above you can use {{ modal.title.length > 20 ? '...' : ''}} to add the suspension points if the string is longer than 20, so the final result is simply:

{{ modal.title | slice:0:20 }}{{ modal.title.length > 20 ? '...' : ''}}

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.

Option 1: Using Maven

If your project uses Maven you can simply include UCanAccess via the following coordinates:

groupId: net.sf.ucanaccess
artifactId: ucanaccess

The following is an excerpt from pom.xml, you may need to update the <version> to get the most recent release:

  <dependencies>
    <dependency>
        <groupId>net.sf.ucanaccess</groupId>
        <artifactId>ucanaccess</artifactId>
        <version>4.0.4</version>
    </dependency>
  </dependencies>

Option 2: Manually adding the JARs to your project

As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:

UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)

Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like

ucanaccess-4.0.1.jar  
  /lib/
    commons-lang-2.6.jar  
    commons-logging-1.1.1.jar  
    hsqldb.jar  
    jackcess-2.1.6.jar

All you need to do is add all five (5) JARs to your project.

NOTE: Do not add loader/ucanload.jar to your build path if you are adding the other five (5) JAR files. The UcanloadDriver class is only used in special circumstances and requires a different setup. See the related answer here for details.

Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path.... Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this

NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.

After adding all five (5) JAR files the "Libraries" folder should look something like this:

IntelliJ IDEA: Choose File > Project Structure... from the main menu. In the "Libraries" pane click the "Add" (+) button and add the five (5) JAR files. Once that is done the project should look something like this:

That's it!

Now "U Can Access" data in .accdb and .mdb files using code like this

// assumes...
//     import java.sql.*;
Connection conn=DriverManager.getConnection(
        "jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
    System.out.println(rs.getString(1));
}

Disclosure

At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.

Convert the List in to String and check whether the Strings are same or not

import java.util.ArrayList;
import java.util.List;

public class ListCompare {

    public static boolean compareList(List ls1,List ls2){
        return ls1.toString().contentEquals(ls2.toString())?true:false;
    }
    public static void main(String[] args) {

        ArrayList<String> one  = new ArrayList<String>();
        ArrayList<String> two  = new ArrayList<String>();

        one.add("one");
        one.add("two");
        one.add("six");

        two.add("ten");

        System.out.println("Output2 :: "+compareList(one,two));
    }
}

In case you have space in your path, wrap it in double quotes:

$ git clone "//serverName/New Folder/Target" f1/

Before installing libgtk2.0-dev and pkg-config or libqt4-dev. Make sure that you have uninstalled opencv. You can confirm this by running import cv2 on your python shell. If it fails, then install the needed packages and re-run cmake .

This problem arrive when you are proxy issue or slow network. You can go with the depth solution or

git fetch --all  or git clone 

    

If this give error of curl 56 Recv failure then download the file via zip or spicify the name of branch instead of --all

git fetch origin BranchName 

The WHERE clause is misplaced, it has to follow the table references and JOIN operations.

Something like this:

 FROM tartikel p1 
 JOIN tartikelpict p2 
   ON p1.kArtikel = p2.kArtikel 
  AND p2.nNr = 1
WHERE p1.dErstellt >= DATE(NOW()) - INTERVAL 7 DAY
ORDER BY p1.kArtikel DESC

EDIT (three plus years later)

The above essentially answers the question "I tried to add a WHERE clause to my query and now the query is returning an error, how do I fix it?"

As to a question about writing a condition that checks a date range of "last 7 days"...

That really depends on interpreting the specification, what the datatype of the column in the table is (DATE or DATETIME) and what data is available... what should be returned.

To summarize: the general approach is to identify a "start" for the date/datetime range, and "end" of that range, and reference those in a query. Let's consider something easier... all rows for "yesterday".

If our column is DATE type. Before we incorporate an expression into a query, we can test it in a simple SELECT

 SELECT DATE(NOW()) + INTERVAL -1 DAY 

and verify the result returned is what we expect. Then we can use that same expression in a WHERE clause, comparing it to a DATE column like this:

 WHERE datecol = DATE(NOW()) + INTERVAL -1 DAY

For a DATETIME or TIMESTAMP column, we can use >= and < inequality comparisons to specify a range

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -1 DAY
   AND datetimecol <  DATE(NOW()) + INTERVAL  0 DAY

For "last 7 days" we need to know if that mean from this point right now, back 7 days ... e.g. the last 7*24 hours , including the time component in the comparison, ...

 WHERE datetimecol >= NOW() + INTERVAL -7 DAY
   AND datetimecol <  NOW() + INTERVAL  0 DAY

the last seven complete days, not including today

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -7 DAY
   AND datetimecol <  DATE(NOW()) + INTERVAL  0 DAY

or past six complete days plus so far today ...

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -6 DAY
   AND datetimecol <  NOW()       + INTERVAL  0 DAY

I recommend testing the expressions on the right side in a SELECT statement, we can use a user-defined variable in place of NOW() for testing, not being tied to what NOW() returns so we can test borders, across week/month/year boundaries, and so on.

SET @clock = '2017-11-17 11:47:47' ;

SELECT DATE(@clock)
     , DATE(@clock) + INTERVAL -7 DAY 
     , @clock + INTERVAL -6 DAY 

Once we have expressions that return values that work for "start" and "end" for our particular use case, what we mean by "last 7 days", we can use those expressions in range comparisons in the WHERE clause.

(Some developers prefer to use the DATE_ADD and DATE_SUB functions in place of the + INTERVAL val DAY/HOUR/MINUTE/MONTH/YEAR syntax.

And MySQL provides some convenient functions for working with DATE, DATETIME and TIMESTAMP datatypes... DATE, LAST_DAY,

Some developers prefer to calculate the start and end in other code, and supply string literals in the SQL query, such that the query submitted to the database is

  WHERE datetimecol >= '2017-11-10 00:00'
    AND datetimecol <  '2017-11-17 00:00'

And that approach works too. (My preference would be to explicitly cast those string literals into DATETIME, either with CAST, CONVERT or just the + INTERVAL trick...

  WHERE datetimecol >= '2017-11-10 00:00' + INTERVAL 0 SECOND
    AND datetimecol <  '2017-11-17 00:00' + INTERVAL 0 SECOND

The above all assumes we are storing "dates" in appropriate DATE, DATETIME and/or TIMESTAMP datatypes, and not storing them as strings in variety of formats e.g. 'dd/mm/yyyy', m/d/yyyy, julian dates, or in sporadically non-canonical formats, or as a number of seconds since the beginning of the epoch, this answer would need to be much longer.

This is one option: http://www.uofr.net/~greg/java/get-resource-listing.html

no problem doing it with asp.... it's most natural to do so with MVC, but can be done with standard asp as well.

The MVC framework has all sorts of helper classes for JSON, if you can, I'd suggest sussing in some MVC-love, if not, you can probably easily just get the JSON helper classes used by MVC in and use them in the context of asp.net.

edit:

here's an example of how to return JSON data with MVC. This would be in your controller class. This is out of the box functionality with MVC--when you crate a new MVC project this stuff gets auto-created so it's nothing special. The only thing that I"m doing is returning an actionResult that is JSON. The JSON method I'm calling is a method on the Controller class. This is all very basic, default MVC stuff:

public ActionResult GetData()
{
    var data = new { Name="kevin", Age=40 };
    return Json(data, JsonRequestBehavior.AllowGet);
}

This return data could be called via JQuery as an ajax call thusly:

$.get("/Reader/GetData/", function(data) { someJavacriptMethodOnData(data); });

CURDATE() will give current date while NOW() will give full date time.

Run the queries, and you will find out whats the difference between them.

SELECT NOW();     -- You will get 2010-12-09 17:10:18
SELECT CURDATE(); -- You will get 2010-12-09

The parseInt function has a "radix" parameter which defines the numeral system used on the conversion, so calling parseInt(jQuery('#something').css('margin-left'), 10); returns the left margin as an Integer.

This is what JSizes use.

For plain ASP.NET MVC Controllers

Create a new attribute

public class AllowCrossSiteJsonAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        filterContext.RequestContext.HttpContext.Response.AddHeader("Access-Control-Allow-Origin", "*");
        base.OnActionExecuting(filterContext);
    }
}

Tag your action:

[AllowCrossSiteJson]
public ActionResult YourMethod()
{
    return Json("Works better?");
}

For ASP.NET Web API

using System;
using System.Web.Http.Filters;

public class AllowCrossSiteJsonAttribute : ActionFilterAttribute
{
    public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
    {
        if (actionExecutedContext.Response != null)
            actionExecutedContext.Response.Headers.Add("Access-Control-Allow-Origin", "*");

        base.OnActionExecuted(actionExecutedContext);
    }
}

Tag a whole API controller:

[AllowCrossSiteJson]
public class ValuesController : ApiController
{

Or individual API calls:

[AllowCrossSiteJson]
public IEnumerable<PartViewModel> Get()
{
    ...
}

For Internet Explorer <= v9

IE <= 9 doesn't support CORS. I've written a javascript that will automatically route those requests through a proxy. It's all 100% transparent (you just have to include my proxy and the script).

Download it using nuget corsproxy and follow the included instructions.

Also you can do like this:

<select class="form-control postType" ng-model="selectedProd">
    <option ng-repeat="product in productList" value="{{product}}">{{product.name}}</option>
</select>

where "selectedProd" will be selected product.

In addition to @Bruno's answer, you need to supply the -name for alias, otherwise Tomcat will throw Alias name tomcat does not identify a key entry error

Sample Command: openssl pkcs12 -export -in localhost.crt -inkey localhost.key -out localhost.p12 -name localhost

function news_get_by_id ( $news_id )
{

    $this->db->select('*');
    $this->db->select("DATE_FORMAT( date, '%d.%m.%Y' ) as date_human",  FALSE );
    $this->db->select("DATE_FORMAT( date, '%H:%i') as time_human",      FALSE );


    $this->db->from('news');

    $this->db->where('news_id', $news_id );


    $query = $this->db->get();

    if ( $query->num_rows() > 0 )
    {
        $row = $query->row_array();
        return $row;
    }

}   
This 

As others have said, you can/should prepend the string with @ (though you could also just escape the backslashes), but what they glossed over (that is, didn't bring it up despite making a change related to it) was the fact that, as I recently discovered, using \ at the beginning of a pathname, without . to represent the current directory, refers to the root of the current directory tree.

C:\foo\bar>cd \
C:\>

versus

C:\foo\bar>cd .\
C:\foo\bar>

(Using . by itself has the same effect as using .\ by itself, from my experience. I don't know if there are any specific cases where they somehow would not mean the same thing.)

You could also just leave off the leading .\ , if you want.

C:\foo>cd bar
C:\foo\bar>

In fact, if you really wanted to, you don't even need to use backslashes. Forwardslashes work perfectly well! (Though a single / doesn't alias to the current drive root as \ does.)

C:\>cd foo/bar
C:\foo\bar>

You could even alternate them.

C:\>cd foo/bar\baz
C:\foo\bar\baz>

...I've really gone off-topic here, though, so feel free to ignore all this if you aren't interested.

You should never assume register_global_variables is turned on. Even if it is, it's deprecated and you should never use it that way.

Refer directly to the $_POST or $_GET variables. Most likely your form is POSTing, so you'd want your code to look something along the lines of this:

<input type="hidden" name="date" id="hiddenField" value="<?php echo $_POST['date'] ?>" />

If this doesn't work for you right away, print out the $_POST or $_GET variable on the page that would have the hidden form field and determine exactly what you want and refer to it.

echo "<pre>";
print_r($_POST);
echo "</pre>";

I have the same problem as @KTCheek in that I need it to execute sequentially. However I figured I would try using IAsyncEnumerable (introduced in .NET Core 3) and await foreach (introduced in C# 8). Here's what I have come up with:

public static class IEnumerableExtensions {
    public static async IAsyncEnumerable<TResult> SelectAsync<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, Task<TResult>> selector) {
        foreach (var item in source) {
            yield return await selector(item);
        }
    }
}

public static class IAsyncEnumerableExtensions {
    public static async Task<List<TSource>> ToListAsync<TSource>(this IAsyncEnumerable<TSource> source) {
        var list = new List<TSource>();

        await foreach (var item in source) {
            list.Add(item);
        }

        return list;
    }
}

This can be consumed by saying:

var inputs = await events.SelectAsync(ev => ProcessEventAsync(ev)).ToListAsync();

Update: Alternatively you can add a reference to "System.Linq.Async" and then you can say:

var inputs = await events
    .ToAsyncEnumerable()
    .SelectAwait(async ev => await ProcessEventAsync(ev))
    .ToListAsync();

The other answers are valid, but the Official Symfony Best Practices guide suggests using the web/ folder to store all assets, instead of different bundles.

Scattering your web assets across tens of different bundles makes it more difficult to manage them. Your designers' lives will be much easier if all the application assets are in one location.

Templates also benefit from centralizing your assets, because the links are much more concise[...]

I'd add to this by suggesting that you only put micro-assets within micro-bundles, such as a few lines of styles only required for a button in a button bundle, for example.

If you want statically make columns not sortable. You can do this way

1. Open the EditColumns window of the DataGridView control.
2. Select the column you want to make not sortable on the left side pane.
3. In the right side properties pane, select the Sort Mode property and select "Not Sortable" in that.

Java doesn't have the concept of a "count" of the used elements in an array.

To get this, Java uses an ArrayList. The List is implemented on top of an array which gets resized whenever the JVM decides it's not big enough (or sometimes when it is too big).

To get the count, you use mylist.size() to ensure a capacity (the underlying array backing) you use mylist.ensureCapacity(20). To get rid of the extra capacity, you use mylist.trimToSize().

Based on official documentation https://developer.android.com/studio/command-line/variables.html you should change ANDROID_AVD_HOME environment var:

Emulator Environment Variables

By default, the emulator stores configuration files under $HOME/.android/ and AVD data under $HOME/.android/avd/. You can override the defaults by setting the following environment variables. The emulator -avd command searches the avd directory in the order of the values in $ANDROID_AVD_HOME, $ANDROID_SDK_HOME/.android/avd/, and $HOME/.android/avd/. For emulator environment variable help, type emulator -help-environment at the command line. For information about emulator command-line options, see Control the Emulator from the Command Line.

• ANDROID_EMULATOR_HOME: Sets the path to the user-specific emulator configuration directory. The default location is
  $ANDROID_SDK_HOME/.android/.
• ANDROID_AVD_HOME: Sets the path to the directory that contains all AVD-specific files, which mostly consist of very large disk images. The default location is $ANDROID_EMULATOR_HOME/avd/. You might want to specify a new location if the default location is low on disk space.

After change or set ANDROID_AVD_HOME you will have to move all content inside ~user/.android/avd/ to your new location and change path into ini file of each emulator, just replace it with your new path

Just in case someone still facing an error after trying to import CommonModule, try to restart the server. It surprisingly work

You have two options here, 1. Use for instead for foreach for iteration.But in your case the collection is IEnumerable and the upper limit of the collection is unknown so foreach will be the best option. so i prefer to use another integer variable to hold the iteration count: here is the code for that:

int i = 0; // for index
foreach (var row in list)
{
    bool IsChecked;// assign value to this variable
    if (IsChecked)
    {    
       // use i value here                
    }
    i++; // will increment i in each iteration
}

A closure occurs when a function has access to a local variable from an enclosing scope that has finished its execution.

def make_printer(msg):
    def printer():
        print msg
    return printer

printer = make_printer('Foo!')
printer()

When make_printer is called, a new frame is put on the stack with the compiled code for the printer function as a constant and the value of msg as a local. It then creates and returns the function. Because the function printer references the msg variable, it is kept alive after the make_printer function has returned.

So, if your nested functions don't

1. access variables that are local to enclosing scopes,
2. do so when they are executed outside of that scope,

then they are not closures.

Here's an example of a nested function which is not a closure.

def make_printer(msg):
    def printer(msg=msg):
        print msg
    return printer

printer = make_printer("Foo!")
printer()  #Output: Foo!

Here, we are binding the value to the default value of a parameter. This occurs when the function printer is created and so no reference to the value of msg external to printer needs to be maintained after make_printer returns. msg is just a normal local variable of the function printer in this context.

I was just wondering how the random number generator in C# works.

That's implementation-specific, but the wikipedia entry for pseudo-random number generators should give you some ideas.

I was also curious how I could make a program that generates random WHOLE INTEGER numbers from 1-100.

You can use Random.Next(int, int):

Random rng = new Random();
for (int i = 0; i < 10; i++)
{
    Console.WriteLine(rng.Next(1, 101));
}

Note that the upper bound is exclusive - which is why I've used 101 here.

You should also be aware of some of the "gotchas" associated with Random - in particular, you should not create a new instance every time you want to generate a random number, as otherwise if you generate lots of random numbers in a short space of time, you'll see a lot of repeats. See my article on this topic for more details.

Small hint which other people didn't talk about: git doesn't record changes if you add empty folders in your project folder. That's it, I was adding empty folders with random names to check wether it was recording changes, it wasn't. But it started to do it as soon as I began adding files in them. Cheers.

Either one of the below three options gets rid of the message (but for different reasons and with different side-effects I suppose):

1. exclude the node_modules directory or explicitly include the directory where your app resides (which presumably does not contain files in excess of 100KB)
2. set the Babel option compact to true (actually any value other than "auto")
3. set the Babel option compact to false (see above)

#1 in the above list can be achieved by either excluding the node_modules directory or be explicitly including the directory where your app resides.

E.g. in webpack.config.js:

let path = require('path');
....
module: {
     loaders: [
          ...
          loader: 'babel',
          exclude: path.resolve(__dirname, 'node_modules/')

... or by using include: path.resolve(__dirname, 'app/') (again in webpack.config.js).

#2 and #3 in the above list can be accomplished by the method suggested in this answer or (my preference) by editing the .babelrc file. E.g.:

$ cat .babelrc 
{
    "presets": ["es2015", "react"],
    "compact" : true
}

Tested with the following setup:

$ npm ls --depth 0 | grep babel

    try:
        letter = word.popleft()
        out = trie_recursion(trie_ds.get(letter, {}), word)
    except IndexError:
        # End of the word
        return {}

    # Dont update if letter already present
    if not trie_ds.has_key(letter):
        trie_ds[letter] = out

    return trie_ds

for word in words:
    # Go through each word
    trie = trie_recursion(trie, deque(word))

pprint.pprint(trie)

Output:

I have found a good work-around for continue (love the break sample above). Here I do not want to list "agency". In PHP I'd "continue" but in twig, I came up with alternative:

{% for basename, perms in permsByBasenames %} 
    {% if basename == 'agency' %}
        {# do nothing #}
    {% else %}
        <a class="scrollLink" onclick='scrollToSpot("#{{ basename }}")'>{{ basename }}</a>
    {% endif %}
{% endfor %}

OR I simply skip it if it doesn't meet my criteria:

{% for tr in time_reports %}
    {% if not tr.isApproved %}
        .....
    {% endif %}
{% endfor %}

Here is a Java 8 solution based on streams.

    public String generateString(String alphabet, int length) {
        return generateString(alphabet, length, new SecureRandom()::nextInt);
    }

    // nextInt = bound -> n in [0, bound)
    public String generateString(String source, int length, IntFunction<Integer> nextInt) {
        StringBuilder sb = new StringBuilder();
        IntStream.generate(source::length)
                .boxed()
                .limit(length)
                .map(nextInt::apply)
                .map(source::charAt)
                .forEach(sb::append);

        return sb.toString();
    }

Use it like

String alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
int length = 12;
String generated = generateString(alphabet, length);
System.out.println(generated);

The function nextInt should accept an int bound and return a random number between 0 and bound - 1.

This works for me, see the example below.

import {Component, ViewChild, ElementRef} from 'angular2/core';_x000D_
_x000D_
@Component({_x000D_
    selector: 'app',_x000D_
    template:  `_x000D_
        <a (click)="toggle($event)">Toggle</a>_x000D_
        <div *ngIf="visible">_x000D_
          <input #control name="value" [(ngModel)]="value" type="text" />_x000D_
        </div>_x000D_
    `,_x000D_
})_x000D_
_x000D_
export class AppComponent {_x000D_
_x000D_
    private elementRef: ElementRef;_x000D_
    @ViewChild('control') set controlElRef(elementRef: ElementRef) {_x000D_
      this.elementRef = elementRef;_x000D_
    }_x000D_
_x000D_
    visible:boolean;_x000D_
_x000D_
    toggle($event: Event) {_x000D_
      this.visible = !this.visible;_x000D_
      if(this.visible) {_x000D_
        setTimeout(() => { this.elementRef.nativeElement.focus(); });_x000D_
      }_x000D_
    }_x000D_
_x000D_
}

I believe that you will have to drop the foreign key constraints first. Then update all of the appropriate tables and remap them as they were.

ALTER TABLE [dbo.Details_tbl] DROP CONSTRAINT [FK_Details_tbl_User_tbl];
-- Perform more appropriate alters
ALTER TABLE [dbo.Details_tbl] ADD FOREIGN KEY (FK_Details_tbl_User_tbl) 
    REFERENCES User_tbl(appId);
-- Perform all appropriate alters to bring the key constraints back

However, unless memory is a really big issue, I would keep the identity as an INT. Unless you are 100% positive that your keys will never grow past the TINYINT restraints. Just a word of caution :)

We can also use Kotlin lambda

editText.setOnKeyListener { _, keyCode, keyEvent ->
        if (keyEvent.action == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_ENTER) {
            Log.d("Android view component", "Enter button was pressed")
            return@setOnKeyListener true
        }
        return@setOnKeyListener false
    }

If you're struggling to get text width with multiline support, so you can use the next code (Swift 5):

func width(text: String, height: CGFloat) -> CGFloat {
    let attributes: [NSAttributedString.Key: Any] = [
        .font: UIFont.systemFont(ofSize: 17)
    ]
    let attributedText = NSAttributedString(string: text, attributes: attributes)
    let constraintBox = CGSize(width: .greatestFiniteMagnitude, height: height)
    let textWidth = attributedText.boundingRect(with: constraintBox, options: [.usesLineFragmentOrigin, .usesFontLeading], context: nil).width.rounded(.up)

    return textWidth
}

And the same way you could find text height if you need to (just switch the constraintBox implementation):

let constraintBox = CGSize(width: maxWidth, height: .greatestFiniteMagnitude)

Or here's a unified function to get text size with multiline support:

func labelSize(for text: String, maxWidth: CGFloat, maxHeight: CGFloat) -> CGSize {
    let attributes: [NSAttributedString.Key: Any] = [
        .font: UIFont.systemFont(ofSize: 17)
    ]

    let attributedText = NSAttributedString(string: text, attributes: attributes)

    let constraintBox = CGSize(width: maxWidth, height: maxHeight)
    let rect = attributedText.boundingRect(with: constraintBox, options: [.usesLineFragmentOrigin, .usesFontLeading], context: nil).integral

    return rect.size
}

Usage:

let textSize = labelSize(for: "SomeText", maxWidth: contentView.bounds.width, maxHeight: .greatestFiniteMagnitude)
let textHeight = textSize.height.rounded(.up)
let textWidth = textSize.width.rounded(.up)

You can use is_uploaded_file():

if(!file_exists($_FILES['myfile']['tmp_name']) || !is_uploaded_file($_FILES['myfile']['tmp_name'])) {
    echo 'No upload';
}

From the docs:

Returns TRUE if the file named by filename was uploaded via HTTP POST. This is useful to help ensure that a malicious user hasn't tried to trick the script into working on files upon which it should not be working--for instance, /etc/passwd.

This sort of check is especially important if there is any chance that anything done with uploaded files could reveal their contents to the user, or even to other users on the same system.

EDIT: I'm using this in my FileUpload class, in case it helps:

public function fileUploaded()
{
    if(empty($_FILES)) {
        return false;       
    } 
    $this->file = $_FILES[$this->formField];
    if(!file_exists($this->file['tmp_name']) || !is_uploaded_file($this->file['tmp_name'])){
        $this->errors['FileNotExists'] = true;
        return false;
    }   
    return true;
}

Changed function for deep casting (using recursion)

/**
 * Translates type
 * @param $destination Object destination
 * @param stdClass $source Source
 */
private static function Cast(&$destination, stdClass $source)
{
    $sourceReflection = new \ReflectionObject($source);
    $sourceProperties = $sourceReflection->getProperties();
    foreach ($sourceProperties as $sourceProperty) {
        $name = $sourceProperty->getName();
        if (gettype($destination->{$name}) == "object") {
            self::Cast($destination->{$name}, $source->$name);
        } else {
            $destination->{$name} = $source->$name;
        }
    }
}

As the recent developed Web Applications are using JavaScript, jQuery, AngularJS, ReactJS etc there is a possibility that to retrieve an attribute of an element through Selenium you have to induce WebDriverWait to synchronize the WebDriver instance with the lagging Web Client i.e. the Web Browser before trying to retrieve any of the attributes.

Some examples:

• Python:

  • To retrieve any attribute form a visible element (e.g. <h1> tag) you need to use the expected_conditions as visibility_of_element_located(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "org"))).get_attribute("attribute_name")
    

  • To retrieve any attribute form an interactive element (e.g. <input> tag) you need to use the expected_conditions as element_to_be_clickable(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "org"))).get_attribute("attribute_name")
    

HTML Attributes

Below is a list of some attributes often used in HTML

Note: A complete list of all attributes for each HTML element, is listed in: HTML Attribute Reference

ECMAScript 2015 (or ES6) came with built-in Reflect object. It is possible to delete object property by calling Reflect.deleteProperty() function with target object and property key as parameters:

Reflect.deleteProperty(myJSONObject, 'regex');

which is equivalent to:

delete myJSONObject['regex'];

But if the property of the object is not configurable it cannot be deleted neither with deleteProperty function nor delete operator:

let obj = Object.freeze({ prop: "value" });
let success = Reflect.deleteProperty(obj, "prop");
console.log(success); // false
console.log(obj.prop); // value

Object.freeze() makes all properties of object not configurable (besides other things). deleteProperty function (as well as delete operator) returns false when tries to delete any of it's properties. If property is configurable it returns true, even if property does not exist.

The difference between delete and deleteProperty is when using strict mode:

"use strict";

let obj = Object.freeze({ prop: "value" });
Reflect.deleteProperty(obj, "prop"); // false
delete obj["prop"];
// TypeError: property "prop" is non-configurable and can't be deleted

$(document).ready(function () {
    $('#tags').on('change', function () {
        $('#tagsname').html('You selected: ' + this.value);
    }).change();
    $('#tags').on('blur', function (e, ui) {
        $('#tagsname').html('You selected: ' + ui.item.value);
    });
});

DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);

assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.

The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.

As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.

If you need to parse other formats, you can check out the Standard DateTime Format Strings.

I came up with my own solution. Use this method, pass any document (dict,list, ObjectId etc) to serialize.

def getSerializable(doc):
    # check if it's a list
    if isinstance(doc, list):
        for i, val in enumerate(doc):
            doc[i] = getSerializable(doc[i])
        return doc

    # check if it's a dict
    if isinstance(doc, dict):
        for key in doc.keys():
            doc[key] = getSerializable(doc[key])
        return doc

    # Process ObjectId
    if isinstance(doc, ObjectId):
        doc = str(doc)
        return doc

    # Use any other custom serializting stuff here...

    # For the rest of stuff
    return doc

**Echocan accept multiple expressions while print cannot. The Print_r () PHP function is used to return an array in a human readable form. It is simply written as

![Print_r ($your_array)][1]

I did three things:

• Put the HTML page in {project.basedir}/resources/static/myPage.html;
• Switch @RestController to @Controller;
• This is my controller:

@RequestMapping(method = RequestMethod.GET, value = "/")
public String aName() {
    return "myPage.html";
}

No particular dependency is needed.

   let concurrentQueue = dispatch_queue_create("com.swift3.imageQueue", DISPATCH_QUEUE_CONCURRENT) //Swift 2 version

   let concurrentQueue = DispatchQueue(label:"com.swift3.imageQueue", attributes: .concurrent) //Swift 3 version

I re-worked your code in Xcode 8, Swift 3 and the changes are marked in contrast to your Swift 2 version.

lst = [("aaaa8"),("bb8"),("ccc8"),("dddddd8")...]

msg = filter(lambda x : x != "8", lst)

print msg

EDIT: For anyone who came across this post, just for understanding the above removes any elements from the list which are equal to 8.

Supposing we use the above example the first element ("aaaaa8") would not be equal to 8 and so it would be dropped.

To make this (kinda work?) with how the intent of the question was we could perform something similar to this

msg = filter(lambda x: x != "8", map(lambda y: list(y), lst))

• I am not in an interpreter at the moment so of course mileage may vary, we may have to index so we do list(y[0]) would be the only modification to the above for this explanation purposes.

What this does is split each element of list up into an array of characters so ("aaaa8") would become ["a", "a", "a", "a", "8"].

This would result in a data type that looks like this

msg = [["a", "a", "a", "a"], ["b", "b"]...]

So finally to wrap that up we would have to map it to bring them all back into the same type roughly

msg = list(map(lambda q: ''.join(q), filter(lambda x: x != "8", map(lambda y: list(y[0]), lst))))

I would absolutely not recommend it, but if you were really wanting to play with map and filter, that would be how I think you could do it with a single line.

You can do this way, providing Json or Any other variable:

1) For exemple, in the controller, you can use Json.NET to provide Json to the ViewBag:

ViewBag.Number = 10;
ViewBag.FooObj = JsonConvert.SerializeObject(new Foo { Text = "Im a foo." });

2) In the View, put the script like this at the bottom of the page.

<script type="text/javascript">
    var number = parseInt(@ViewBag.Number); //Accessing the number from the ViewBag
    alert("Number is: " + number);
    var model = @Html.Raw(@ViewBag.FooObj); //Accessing the Json Object from ViewBag
    alert("Text is: " + model.Text);
</script> 

The problem was that you attempted to modify the list you were referencing within the loop that used the list len(). When you remove the item from the list, then the new len() is calculated on the next loop.

For example, after the first run, when you removed (i) using l.pop(i), that happened successfully but on the next loop the length of the list has changed so all index numbers have been shifted. To a certain point the loop attempts to run over a shorted list throwing the error.

Doing this outside the loop works, however it would be better to build and new list by first declaring and empty list before the loop, and later within the loop append everything you want to keep to the new list.

For those of you who may have come to the same problem.

I had the same problem. I installed Eclipse 3.7 into a new folder, and created a new workspace. I launch Eclipse with a -data argument to reference the new workspace.

When I attempt to connect to the marketplace to get the SVN and Maven plugins, I get the same issues described in OP.

After a few more tries, I cleared the proxy settings for SOCKS protocol, and I was able to connect to the marketplace.

So the solution for me was to configure the manual settings for HTTP and HTTPS proxy, clear the settings for SOCKS, and restart Eclipse.

It is not possible directly. You may as well write some preprocessor which can handle that.

If I understand it correctly then below are the things that can be helpful to achieve that:

• Use a pre-processor which will run through your JS files for example looking for patterns like "@import somefile.js" and replace them with the content of the actual file. Nicholas Zakas(Yahoo) wrote one such library in Java which you can use (http://www.nczonline.net/blog/2009/09/22/introducing-combiner-a-javascriptcss-concatenation-tool/)

• If you are using Ruby on Rails then you can give Jammit asset packaging a try, it uses assets.yml configuration file where you can define your packages which can contain multiple files and then refer them in your actual webpage by the package name.

• Try using a module loader like RequireJS or a script loader like LabJs with the ability to control the loading sequence as well as taking advantage of parallel downloading.

JavaScript currently does not provide a "native" way of including a JavaScript file into another like CSS ( @import ), but all the above mentioned tools/ways can be helpful to achieve the DRY principle you mentioned. I can understand that it may not feel intuitive if you are from a Server-side background but this is the way things are. For front-end developers this problem is typically a "deployment and packaging issue".

Hope it helps.

For Mac OS X Yosemite I was able to use the open command.

Usage: open [-e] [-t] [-f] [-W] [-R] [-n] [-g] [-h] [-b <bundle identifier>] [-a <application>] [filenames] [--args arguments]
Help: Open opens files from a shell.
      By default, opens each file using the default application for that file.  
      If the file is in the form of a URL, the file will be opened as a URL.
Options: 
      -a                Opens with the specified application.
      -b                Opens with the specified application bundle identifier.
      -e                Opens with TextEdit.
      -t                Opens with default text editor.
      -f                Reads input from standard input and opens with TextEdit.
      -F  --fresh       Launches the app fresh, that is, without restoring windows. Saved persistent state is lost, excluding Untitled documents.
      -R, --reveal      Selects in the Finder instead of opening.
      -W, --wait-apps   Blocks until the used applications are closed (even if they were already running).
          --args        All remaining arguments are passed in argv to the application's main() function instead of opened.
      -n, --new         Open a new instance of the application even if one is already running.
      -j, --hide        Launches the app hidden.
      -g, --background  Does not bring the application to the foreground.
      -h, --header      Searches header file locations for headers matching the given filenames, and opens them.

This worked for me:

open eclipse.app --args clean

Try this

@RequestMapping(value = "proffessional", method = RequestMethod.POST)
    public @ResponseBody
    String forgotPassword(@ModelAttribute("PROFESSIONAL") UserProfessionalForm professionalForm,
            BindingResult result, Model model) {

        UserProfileVO userProfileVO = new UserProfileVO();
        userProfileVO.setUser(sessionData.getUser());
        userService.saveUserProfile(userProfileVO);
        model.addAttribute("professional", professionalForm);
        return "Your Professional Details Updated";
    }

I think I got there in the end.

The task is like this:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default({}) | combine( {item.item.name: item.stdout} ) }}"
  with_items: "{{ people.results }}"

It loops through each of the dicts (item) in the people.results array, each time creating a new dict like {Bob: "male"}, and combine()s that new dict in the genders array, which ends up like:

{
    "Bob": "male",
    "Thelma": "female"
}

It assumes the keys (the name in this case) will be unique.

I then realised I actually wanted a list of dictionaries, as it seems much easier to loop through using with_items:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default([]) + [ {'name': item.item.name, 'gender': item.stdout} ] }}"
  with_items: "{{ people.results }}"

This keeps combining the existing list with a list containing a single dict. We end up with a genders array like this:

[
    {'name': 'Bob', 'gender': 'male'},
    {'name': 'Thelma', 'gender': 'female'}
]

in my case, only height: 100vh fix the problem with the expected behavior

You can use new C# 6.0 Language Features:

• replace delegate (s) => { return Convert.ToInt32(s); } with corresponding method group Convert.ToInt32
• replace redundant constructor call: new Converter<string, int>(Convert.ToInt32) with: Convert.ToInt32

The result will be:

var intList = new List<int>(Array.ConvertAll(sNumbers.Split(','), Convert.ToInt32));

If you're going to use compile-time recursion, then you probably also want to use divide & conquer to avoid hitting template depth limits:

#include <iostream>

template<int L, int U>
struct range
{
    enum {H = (L + U) / 2};
    static inline void f ()
    {
        range<L, H>::f ();
        range<H+1, U>::f ();
    }
};

template<int L>
struct range<L, L>
{
    static inline void f ()
    {
        std::cout << L << '\n';
    }
};

int main (int argc, char* argv[])
{
    range<1, 1000>::f ();
    return 0;
}

I've tried a some of the solutions in this thread, and unfortunately, I found some of them to be cumbersome (i.e. requiring excessive effort when doing something non-trivial) and inelegant. Consequently, I thought I'd throw my preferred solution, web2py HTML helper objects, into the mix.

First, install the the standalone web2py module:

pip install web2py

Unfortunately, the above installs an extremely antiquated version of web2py, but it'll be good enough for this example. The updated source is here.

Import web2py HTML helper objects documented here.

from gluon.html import *

Now, you can use web2py helpers to generate XML/HTML.

words = ['this', 'is', 'my', 'item', 'list']
# helper function
create_item = lambda idx, word: LI(word, _id = 'item_%s' % idx, _class = 'item')
# create the HTML
items = [create_item(idx, word) for idx,word in enumerate(words)]
ul = UL(items, _id = 'my_item_list', _class = 'item_list')
my_div = DIV(ul, _class = 'container')

>>> my_div

<gluon.html.DIV object at 0x00000000039DEAC8>

>>> my_div.xml()
# I added the line breaks for clarity
<div class="container">
   <ul class="item_list" id="my_item_list">
      <li class="item" id="item_0">this</li>
      <li class="item" id="item_1">is</li>
      <li class="item" id="item_2">my</li>
      <li class="item" id="item_3">item</li>
      <li class="item" id="item_4">list</li>
   </ul>
</div>

Here is example code what I did for an asynchronous method

@RequestMapping(value = "/import", method = RequestMethod.POST)
@ResponseStatus(value = HttpStatus.OK)
public void importDataFromFile(@RequestParam("file") MultipartFile file) 
{
    accountingSystemHandler.importData(file, assignChargeCodes);
}

You do not need to return any thing from your method all you need to use this annotation so that your method should return OK in every case

@ResponseStatus(value = HttpStatus.OK)

Here's a handy site to test out your headers. You can see your browser headers and also use cURL to reflect back whatever headers you send.

For example, you can validate the content negotiation like this.

This Accept header prefers plain text so returns in that format:-

$ curl -H "Accept: application/json;q=0.9,text/plain" http://gethttp.info/Accept
application/json;q=0.9,text/plain

Whereas this one prefers JSON and so returns in that format:-

$ curl -H "Accept: application/json,text/*;q=0.99" http://gethttp.info/Accept
{
   "Accept": "application/json,text/*;q=0.99"
}

When you start using ECMAScript 6 this error thrown by your IDE.

There are two options available:

if you have only one file and want to use the es6 then simply add below line at the top of the file.

/*jshint esversion: 6 */

Or if you have number of js file or you are using any framework(like nodejs express)you can create a new file named .jshintrc in your root directory and add code below in the file:

{
    "esversion": 6
}

If you want to use the es6 version onward for each project you can configure your IDE.

Tab as Enter: create a user control which inherits textbox, override the KeyPress method. If the user presses enter you can either call SendKeys.Send("{TAB}") or System.Windows.Forms.Control.SelectNextControl(). Note you can achieve the same using the KeyPress event.

Focus Entire text: Again, via override or events, target the GotFocus event and then call TextBox.Select method.

To answer your question directly: while the loop condition is True. Which it always is, in this particular bit of code.

For the carousel, I believe all images have to be exactly the same height and width.

Also, when you refer back to the scaffolding page from bootstrap, I'm pretty sure that span16 = 940px. With this in mind, I think we can assume that if you have a

<div class="row">
     <div class="span4"> 
        <!--left content div guessing around 235px in width -->
     </div>
     <div class="span8">
        <!--right content div guessing around 470px in width -->
     </div>
</div>

So yes, you have to be careful when setting the spans space within a row because if the image width is to large, it will send your div over into the next "row" and that is no fun :P

Link 1

Try to use createChild() method of DOM or insertRow() and insertCell() method of table object in script tag.

If your using Node.js or writing JavaScript with browserify, consider the "once" npm module:

var once = require('once')

function load (file, cb) {
  cb = once(cb)
  loader.load('file')
  loader.once('load', cb)
  loader.once('error', cb)
}

When you initialize unsigned int a to -1; it means that you are storing the 2's complement of -1 into the memory of a.
Which is nothing but 0xffffffff or 4294967295.

Hence when you print it using %x or %u format specifier you get that output.

By specifying signedness of a variable to decide on the minimum and maximum limit of value that can be stored.

Like with unsigned int: the range is from 0 to 4,294,967,295 and int: the range is from -2,147,483,648 to 2,147,483,647

For more info on signedness refer this

For Linux or OSX, you can use ipfw.

From Quora (http://www.quora.com/What-is-the-best-tool-to-simulate-a-slow-internet-connection-on-a-Mac)

Essentially using a firewall to throttle all network data:

Define a rule that uses a pipe to reroute all traffic from any source address to any destination address, execute the following command (as root, or using sudo):

$ ipfw add pipe 1 all from any to any

To configure this rule to limit bandwidth to 300Kbit/s and impose 200ms of latency each way:

$ ipfw pipe 1 config bw 300Kbit/s delay 200ms

To remove all rules and recover your original network connection:

$ ipfw flush

{ title: "One", key: "1" }

Is not what you think. As an expression, it's an Object literal, but as a statement, it's:

{                // new block
    title:       // define a label called 'title' for goto statements
        "One",   // statement: the start of an expression which will be ignored
        key:     // ...er, what? you can't have a goto label in the middle of an expression
                 // ERROR

Unfortunately eval() does not give you a way to specify whether you are giving it a statement or an expression, and it tends to guess wrong.

The usual solution is indeed to wrap anything in parentheses before sending it to the eval() function. You say you've tried that on the server... clearly somehow that isn't getting through. It should be waterproof to say on the client end, whatever is receiving the XMLHttpRequest response:

eval('('+responseText+')');

instead of:

eval(responseText);

as long as the response is really an expression not a statement. (eg. it doesn't have multiple, semicolon-or-newline-separated clauses.)

make the checkbox non-focusable, and on list-item click do this, here codevalue is the position.

    Arraylist<Integer> selectedschools=new Arraylist<Integer>();

    lvPickSchool.setOnItemClickListener(new AdapterView.OnItemClickListener() 
  {

   @Override
        public void onItemClick(AdapterView<?> parent, View view, int codevalue, long id)
   {
                      CheckBox cb = (CheckBox) view.findViewById(R.id.cbVisitingStatus);

            cb.setChecked(!cb.isChecked());
            if(cb.isChecked())
            {

                if(!selectedschool.contains(codevaule))
                {
                    selectedschool.add(codevaule);
                }
            }
            else
            {
                if(selectedschool.contains(codevaule))
                {
                    selectedschool.remove(codevaule);
                }
            }
        }
    });

LESS has guard expressions for mixins, not individual attributes.

So you'd create a mixin like this:

.debug(@debug) when (@debug = true) {
    header {
      background-color: yellow;
      #title {
          background-color: orange;
      }
    }

    article {
      background-color: red;
    }
}

And turn it on or off by calling .debug(true); or .debug(false) (or not calling it at all).

Old answer:

First, in your AppDelegate .h file:

#import <AVFoundation/AVFoundation.h>

@interface AppDelegate : NSObject <UIApplicationDelegate> {

    AVCaptureSession *torchSession;

}

@property (nonatomic, retain) AVCaptureSession * torchSession;

@end

Then in your AppDelegate .m file:

@implementation AppDelegate

@synthesize torchSession;

- (void)dealloc {
    [torchSession release];

    [super dealloc];
}

- (id) init {
    if ((self = [super init])) {

    // initialize flashlight
    // test if this class even exists to ensure flashlight is turned on ONLY for iOS 4 and above
        Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
        if (captureDeviceClass != nil) {

            AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];

            if ([device hasTorch] && [device hasFlash]){

                if (device.torchMode == AVCaptureTorchModeOff) {

                NSLog(@"Setting up flashlight for later use...");

                    AVCaptureDeviceInput *flashInput = [AVCaptureDeviceInput deviceInputWithDevice:device error: nil];
                    AVCaptureVideoDataOutput *output = [[AVCaptureVideoDataOutput alloc] init];

                    AVCaptureSession *session = [[AVCaptureSession alloc] init];

                [session beginConfiguration];
                    [device lockForConfiguration:nil];

                    [session addInput:flashInput];
                    [session addOutput:output];

                    [device unlockForConfiguration];

                    [output release];

                [session commitConfiguration];
                [session startRunning];

                [self setTorchSession:session];
                [session release];
                    }

            }

        }
    } 
    return self;
}

Then anytime you want to turn it on, just do something like this:

// test if this class even exists to ensure flashlight is turned on ONLY for iOS 4 and above
Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
if (captureDeviceClass != nil) {

    AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];

    [device lockForConfiguration:nil];

    [device setTorchMode:AVCaptureTorchModeOn];
    [device setFlashMode:AVCaptureFlashModeOn];

    [device unlockForConfiguration];

}

And similar for turning it off:

// test if this class even exists to ensure flashlight is turned on ONLY for iOS 4 and above
Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
if (captureDeviceClass != nil) {

    AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];

    [device lockForConfiguration:nil];

    [device setTorchMode:AVCaptureTorchModeOff];
    [device setFlashMode:AVCaptureFlashModeOff];

    [device unlockForConfiguration];
}

No, you will have to use OR to combine your LIKE statements:

SELECT 
   * 
FROM 
   table
WHERE 
   column LIKE 'Text%' OR 
   column LIKE 'Link%' OR 
   column LIKE 'Hello%' OR
   column LIKE '%World%'

Have you looked at Full-Text Search?

I started with @jhoff's solution, but rewrote it to use width/height parameters, and using arcTo makes it quite a bit more terse:

CanvasRenderingContext2D.prototype.roundRect = function (x, y, w, h, r) {
  if (w < 2 * r) r = w / 2;
  if (h < 2 * r) r = h / 2;
  this.beginPath();
  this.moveTo(x+r, y);
  this.arcTo(x+w, y,   x+w, y+h, r);
  this.arcTo(x+w, y+h, x,   y+h, r);
  this.arcTo(x,   y+h, x,   y,   r);
  this.arcTo(x,   y,   x+w, y,   r);
  this.closePath();
  return this;
}

Also returning the context so you can chain a little. E.g.:

ctx.roundRect(35, 10, 225, 110, 20).stroke(); //or .fill() for a filled rect

Solved using JavaScript + jQuery! I just need similar solution to my project but current solution with HTML and CSS is not ok for me because there is issue with column height + I need more then one column to be fixed. So I create simple javascript solution using jQuery

You can try it here https://jsfiddle.net/kindrosker/ffwqvntj/

All you need is setup home many columsn will be fixed in data-count-fixed-columns parameter

<table class="table" data-count-fixed-columns="2" cellpadding="0" cellspacing="0">

and run js function

app_handle_listing_horisontal_scroll($('#table-listing'))

As of Java 8 and Stream API you can use Arrays.stream and Collectors.toList:

String[] array = new String[]{"a", "b", "c"};
List<String> list = Arrays.stream(array).collect(Collectors.toList());

This is practical especially if you intend to perform further operations on the list.

String[] array = new String[]{"a", "bb", "ccc"};
List<String> list = Arrays.stream(array)
                          .filter(str -> str.length() > 1)
                          .map(str -> str + "!")
                          .collect(Collectors.toList());
